The Company shall default in the performance or observance of any term, covenant, condition or agreement contained in this Agreement (other than as specifically provided for otherwise in Section 6.4) or any other Purchase Documents and such default shall continue for a period of 30 days after written notice thereof has been given to the Company by the Majority Purchasers in the manner provided herein. 6.6 Debt Cross-Default. The Company shall (i) be in default in the payment of any Indebtedness (as defined below) due to any party other than the Purchasers, the aggregate outstanding amount of which Indebtedness is in excess of $1,000,000, beyond the period of grace, if any, provided in the instrument or agreement under which such Indebtedness was created, or (ii) default in the observance or performance of any other agreement or condition relating to any Indebtedness (other than the Indebtedness referred to in clause (i) above), the aggregate outstanding amount of which other Indebtedness is in excess of $1,000,000 or contained in any instrument or agreement evidencing, securing or relating thereto or any other default or event shall occur or condition exist, the effect of which default or other event or condition is to cause, or to permit the holder or holders of such other Indebtedness (or a trustee or agent on behalf of such holder or holders) to cause, with the giving of notice if required, any such other Indebtedness to become due prior to its stated maturity (any applicable grace period having expired). "Indebtedness," as applied to the Company, means without duplication: (a) all items (except items of capital stock, surplus or undivided profits) which in accordance with GAAP would be included in determining total liabilities as shown on the liability side of a balance sheet of the Company as at the date as of which Indebtedness is to be determined; (b) to the extent not included in the foregoing, all indebtedness, obligations, and liabilities secured by any mortgage, pledge, lien, conditional sale or other title retention agreement or other security interest to which any property or asset owned or held by the Company is subject, whether or not the indebtedness, obligations or liabilities secured thereby shall have been assumed by the Company; and (c) to the extent not included in the foregoing, all indebtedness, obligations and liabilities of others which the Company has directly or indirectly guaranteed, endorsed (other than for collection or deposit in the ordinary course of business), sold with recourse, or agreed (contingently or otherwise) to purchase or repurchase or otherwise acquire or in respect of which the Company has agreed to supply or advance funds (whether by way of loan, stock purchase, capital contribution or otherwise) or otherwise to become directly or indirectly liable. 6.7 Other Cross-Defaults. The Company shall default in the payment when due, or in the performance or observance, of any obligation or condition of any Material Contract (as defined below) unless, but only as long as, the existence of any such default is being contested by the Company in good faith by appropriate proceedings and 13 adequate reserves in respect thereof have been established on the books of the Company to the extent required by GAAP. "Material Contract" means any contract or agreement, written or oral, of the Company, the failure to comply with which could reasonably be expected to have a material adverse effect on the Company or its business. 6.8 Change in Control. Any person or group of persons (within the meaning of Section 13(d)(3) of the Securities Exchange Act of 1934, as amended) other than Inberdon Enterprises, Ltd. and its affiliates, shall obtain ownership or control in one or more series of transactions of more than 25% of the Common Stock or 25% of the voting power of the Company entitled to vote in the election of members of the board of directors of the Company, or there shall have occurred under any indenture or other instrument evidencing any Indebtedness in excess of $1,000,000 any "change in control" (as defined in such indenture or other evidence of Indebtedness) obligating the Company to repurchase, redeem or repay all or any part of the Indebtedness or capital stock provided for therein (any such event, a "Change in Control"). 6.9 Voluntary Bankruptcy Proceeding. The Company shall (i) commence a voluntary case under the Federal bankruptcy laws (as now or hereafter in effect), (ii) file a petition seeking to take advantage of any other laws, domestic or foreign, relating to bankruptcy, insolvency, reorganization, winding up or composition for adjustment of debts, (iii) consent to or fail to contest in a timely and appropriate manner any petition filed against it in an involuntary case under such bankruptcy laws or other laws, (iv) apply for or consent to, or fail to contest in a timely and appropriate manner, the appointment of, or the taking of possession by, a receiver, custodian, trustee, or liquidator of itself or of a substantial part of its property, domestic or foreign, (v) admit in writing its inability to pay its debts as they become due, (vi) make a general assignment for the benefit of creditors, or (vii) take any corporate action for the purpose of authorizing any of the foregoing. 6.10 Involuntary Bankruptcy Proceeding. A case or other proceeding shall be commenced against the Company in any court of competent jurisdiction seeking (i) relief under the Federal bankruptcy laws (as now or hereafter in effect) or under any other laws, domestic or foreign, relating to bankruptcy, insolvency, reorganization, winding-up or adjustment of debts, or (ii) the appointment of a trustee, receiver, custodian, liquidator or the like for the Company or for all or any substantial part of its assets, domestic or foreign, and such case or proceeding shall continue without dismissal or stay for a period of 60 consecutive days, or an order granting the relief requested in such case or proceeding (including without limitation an order for relief under such Federal bankruptcy laws) shall be entered. 6.11 Failure of Agreements. Any provision of this Agreement or of any other Purchase Document shall for any reason cease to be valid and binding on the Company. 6.12 Judgment. A judgment or order for the payment of money which causes the aggregate amount of all such judgments to exceed $1,000,000 in any fiscal year shall be entered against the Company by any court and such judgment or order shall continue without discharge or stay for a period of 30 days. 14 7.

EACH PURCHASER FURTHER WARRANTS AND REPRESENTS THAT SUCH PURCHASER HAS REVIEWED THIS WAIVER WITH SUCH PURCHASER'S LEGAL COUNSEL, AND THAT SUCH PURCHASER KNOWINGLY AND VOLUNTARILY WAIVES ITS JURY TRIAL RIGHTS FOLLOWING CONSULTATION WITH LEGAL COUNSEL. THIS WAIVER IS IRREVOCABLE, MEANING THAT IT MAY NOT BE MODIFIED EITHER ORALLY OR IN WRITING, AND THIS WAIVER SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS, RENEWALS, SUPPLEMENTS OR MODIFICATIONS TO THE PURCHASE DOCUMENTS.

Any such amendment of the Purchase Documents, or waiver of any term or provision of the Purchase Documents, made with such written consent of the Company and the Majority Purchasers shall be binding upon each Purchaser under this Agreement; provided, however, that, without the written consent of all of the Purchasers and the Company, no such amendment or waiver will be made which would (i) extend the time for payment of any principal or interest of any Note (ii) reduce the principal amount of or interest due under any Note, (iii) except as otherwise set forth in the Warrants, decrease the number of Warrant Shares that may be purchased under any Warrant, (iv) modify the Warrant Exercise Term (as defined in the Warrants), or (v) except as permitted by the terms of the Warrants, adjust the Exercise Price (as defined in the Warrants) set forth in the Warrants. 7.6 Notices.
