If an Event of Default shall have occurred, then, and in each and every such case, the full amount of this Note, including all accrued and unpaid interest hereon, shall be immediately due and payable (in the case of events described in clauses (a) and (b) above, upon declaration by the Holder), such amount becoming so due and payable without presentation, protest or further demand or notice of any kind, all of which are hereby expressly waived, and Holder shall be entitled to receive, to the extent lawful, reasonable attorneys' fees for the collection of such amount. In the event that, for any reason, Paul Mendez ceases to serve as the Chief Executive Officer of Maker, Maker covenants that, within 120 days from such cessation, it will select a new Chief Executive Officer and will notify Holder of such selection. If, in its discretion, Holder is dissatisfied with the selection of the new Chief Executive Officer made by Maker, Holder will have an option, exercisable for 180 days from the date such new Chief Executive Officer takes office, to require Maker to prepay this Note in full (including all unpaid principal and interest) six months from the time Holder notifies Maker in writing of Holder's exercise of such option. Maker hereby covenants that for such time as amounts are outstanding under this Note, Maker shall make any cash payments with respect to any shares of the Series A Preferred Stock, par value $1.00 per share, of Maker (the "Preferred Stock"), only in accordance with the following limitations (the "Cash Limitations"), subject, however, to the restrictions imposed by the terms of the Senior Debt: (a) Maker shall pay dividends on the Preferred Stock (including accrued but unpaid dividends and current dividends) in cash only from Available Net Income. For purposes of this Note, Available Net Income shall mean 100% of net income earned by Maker beginning February 1, 1997 and thereafter, less any amounts paid with ---- respect to the Preferred Stock (whether in the form of dividends, redemption payments or repurchase payments) from February 1, 1997 to the date of the payment for which the determination of Available Net Income is being made; and (b) Maker shall redeem or repurchase Preferred Stock with cash only from 50% of Available Net Income as of the date of such redemption or repurchase. Notwithstanding the foregoing Cash Limitations, Maker shall be permitted to make payments with respect to the Preferred Stock (whether in the form of dividends, redemptions or repurchases) in amounts in excess of Available Net Income at the time of such payment (an "Excess Payment"), subject, however, to the restrictions imposed by the terms of the Senior Debt and provided that: ------------- (a) any such Excess Payment is made through the issuance of notes subordinate in right of payment to this Note; and (b) such subordinated notes are serviced only to the extent of 50% of Available Net Income. The foregoing shall not preclude Maker from exchanging such Preferred Stock for Common Stock or for other classes or series of capital stock of Maker (provided, however, that the restrictions on dividends and redemptions shall apply to any stock for which such Preferred Stock is exchanged). As an inducement to Holder to accept this Note from Maker in accordance with the terms of the Purchase Agreement, Maker hereby covenants that for such time as amounts are outstanding under this Note, Maker will not, in connection with the incurrence of debt other than any debt obtained from the Senior Creditor, or its successors and/or assigns, agree with the lender of such debt to design events of default under such debt with a view to avoiding the payment of amounts due under this Note in accordance with its terms. Maker hereby covenants that if, at any time while this Note is outstanding, Maker ceases to be required under the Securities Exchange Act of 1934 (the "Exchange Act") to file periodic reports with the Securities and Exchange Commission, it will furnish to Holder (i) within 45 days from the end of each of the first three quarters of each fiscal year of Maker, financial statements of the nature required to be filed by Form 10-Q under the Exchange Act for each such fiscal quarter and (ii) within 90 days from the end of each fiscal year of Maker, audited financial statements for each such fiscal year. Any notice, presentation or demand to or upon Maker in respect of this Note may be given or made in writing to the address set forth above, and shall be deemed to be duly given if personally delivered with receipt acknowledged, if mailed by registered or certified mail, first class, postage prepaid, or if delivered by a nationally recognized overnight courier service to such address, or, if any other address shall at any time be designated for this purpose by Maker in writing to Holder, to such other address. The provisions of this Note shall be construed and interpreted, and all rights and obligations hereunder determined, in accordance with the laws of the State of New York, without reference to the conflict of laws principles thereof. This Note shall bind Maker and its successors and assigns, and shall inure to the benefit of Holder and its successors and assigns. IN WITNESS WHEREOF, Maker has duly executed this Note on the day and year first above written. FIRECOM, INC.
