(a) The Company for itself, its successors and assigns, covenants and agrees, and each Holder of this Note by its acceptance of this Note likewise covenants and agrees, that to the extent provided below the payment of the principal of and interest on this Note is hereby expressly subordinated and junior in right of payment, to the extent and in the manner hereinafter set forth, to all Senior Indebtedness. For purposes hereof, Senior Indebtedness is defined as: -2- (i) the principal of, premium, if any, any interest (including without limitation any interest on interest and post-petition interest) on, and all obligations of the Company for any costs and expenses with respect to, all liabilities of the Company, direct or contingent, joint, several or independent, now or hereafter existing, due or to become due, whether created directly or acquired by assignment or otherwise, under or in respect of that certain Amended and Restated Credit Agreement, dated as of April 12, 1995, among, the Company, The Bank of New York, Chemical Bank and the other parties referred to therein (as heretofore and as hereafter amended, modified and supplemented from time to time, the 'Bank Credit Agreement') and any of the other Loan Documents (as defined in the Bank Credit Agreement); and (ii) all extensions, renewals and refundings of any of the foregoing. (b) Upon the acceleration of any Senior Indebtedness or upon the maturity of the entire principal amount of any Senior Indebtedness by lapse of time, acceleration or otherwise, all such Senior Indebtedness which has been so accelerated or matured shall first indefeasibly be paid in full in cash before any payment is made by the Company or any Person acting on behalf of the Company on account of any obligations evidenced by this Note. (c) The Company shall not pay any obligations evidenced by this Note if there exists a Default or Event of Default (as such terms are defined in the instruments evidencing Senior Indebtedness including, without limitation, the Bank Credit Agreement) with respect to any Senior Indebtedness (hereinafter referred to as a 'Blockage Event'). The Company shall resume payment of this Note and a Blockage Event shall be deemed to have terminated: (i) when such Default or Event of Default on Senior Indebtedness, as applicable, is cured or waived; or (ii) when the Holder hereof shall have cured any such Default or Event of Default on Senior Indebtedness to the extent such Default or Event of Default can be cured by payment of money, which amount shall be added to the principal amount owing to the Holder pursuant to this Note; or (iii) 180 days after the occurrence of such Default or Event of Default, provided, that at the end of such 180 days, if any of the following events occurs, the Blockage Event shall continue: (A) a Default in payment of any amount with respect to the Senior Indebtedness; (B) an acceleration of the Senior Indebtedness; or (C) the occurrence of an event of the type described in Section 6 hereof, provided further, that a Blockage Event may be deemed to occur, with respect to any single specified Default or Event of Default, only once for each 360 day period. -3- (d) At any time there exists a Blockage Event, (i) the Company shall not, directly or indirectly, make any payment of any part of this Note, (ii) the Holder hereof shall not demand or accept from the Company or any other Person any such payment or cancel, set off or otherwise discharge any part of the indebtedness represented by this Note, and (iii) neither the Company nor the Holder hereof shall otherwise take or permit any action prejudicial to or inconsistent with the priority position of any holder of Senior Indebtedness over the Holder of this Note. (e) Any holder of Senior Indebtedness is hereby authorized to demand specific performance of this Note, whether or not the Company shall have complied with the provisions hereof applicable to it, at any time when the Holder hereof shall have failed to comply with any provision hereof applicable to him. The Holder hereby irrevocably waives any defense based on the adequacy of a remedy at law which might be asserted as a bar to the remedy of specific performance hereof in any action brought therefor by any holder of Senior Indebtedness. The Holder further (i) waives presentment, demand, notice and protest in connection with all negotiable instruments evidencing Senior Indebtedness, notice of any loan made, extension granted or other action taken in reliance hereon and all demands and notices of every kind in connection with this Note or Senior Indebtedness; and (ii) assents to any renewal, extension or postponement of the time of payment of Senior Indebtedness or any other indulgence with respect thereto, to any substitution, exchange or release of collateral therefor and to the addition or release of any Person primarily or secondarily liable thereon. (f) The Company and the Holder shall execute and deliver to any holder of Senior Indebtedness such further instruments and shall take such further action as such holder of Senior Indebtedness may at any time or times reasonably request in order to evidence the subordination of the obligations hereunder and to otherwise carry out the provisions and intent of this Note. (g) No right of any holder of Senior Indebtedness to enforce the subordination of the obligations shall be impaired by any act or failure to act by the Company or the Holder or by their failure to comply with this Note or any other agreement or document evidencing, related to or securing the obligations hereunder. Without in any way limiting the generality of the preceding sentence, the holders of Senior Indebtedness may, at any time and from time to time, without the consent of or notice to the Holder, without incurring responsibility to the Holder and without impairing or releasing the subordination provided in this Note or the obligations of the holder hereof to the holders of Senior Indebtedness, do any one or more of the following: (i) change the manner, place or terms of payment of, or renew or alter, any Senior Indebtedness, or otherwise amend or supplement in any manner, any Senior Indebtedness or any instrument evidencing the same or any agreement under which Senior Indebtedness is outstanding; (ii) sell, exchange, release or otherwise deal with any property pledged, mortgaged or otherwise securing any Senior Indebtedness; (iii) release any Person or entity liable in any manner for the collection of any Senior Indebtedness; and (iv) exercise or refrain from exercising any rights against the Company or any other Person or entity. -4- (h) In the event that the Company shall make any payment or prepayment to the Holder on account of the obligations under this Note which is prohibited by this Section 5, 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 and priorities of Senior Indebtedness held by them) to the extent necessary to pay all Senior Indebtedness due to such holders in full in accordance with its terms (whether or not such Senior Indebtedness is due and owing), after giving effect to any concurrent payment or distribution to or for the holders of such Senior Indebtedness. (i) After all Senior Indebtedness indefeasibly is paid in full and until the obligations under this Note are paid in full, the Holder shall be subrogated to the rights of holders of Senior Indebtedness to the extent that distributions otherwise payable to the Holder have been applied to the payment of Senior Indebtedness. For purposes of such subrogation, no payments or distributions to holders of such Senior Indebtedness of any cash, property or securities to which the Holder would be entitled except for the provisions of this Section 5 and no payment over pursuant to the provisions of this Section 5 to holders of such Senior Indebtedness by the Holder, shall, as between the Company, its creditors, other than holders of such Senior Indebtedness, and the Holder, be deemed to be a payment by the Company to or on account of such Senior Indebtedness, it being understood that the provisions of this Section 5 are solely for the purpose of defining the relative rights of the holders of such Senior Indebtedness, on the one hand, and the Holder hereof, on the other hand. 6. Primacy of Senior Indebtedness Claims as Against the Holder. In any insolvency, receivership, bankruptcy, dissolution, liquidation or reorganization proceeding, or in any other proceeding, whether voluntary or involuntary, by or against the Company under any bankruptcy or insolvency law or laws relating to relief of debtors, to compositions, extensions, or readjustments of indebtedness: (a) the claims of any holders of Senior Indebtedness against the Company shall be paid indefeasibly in full in cash before any payment is made to the Holder of this Note; (b) until all Senior Indebtedness is indefeasibly paid in full any distribution to which the Holder would be entitled but for this Section 6 shall be made to holders of Senior Indebtedness; and (c) the holders of Senior Indebtedness shall have the right to enforce, collect and receive every such payment or distribution and give acquittance therefor. In furtherance of the foregoing, in the event that the Company shall file or have filed against it a petition under any chapter of Title 11 of the United States Code or any comparable statute, with the result that the Company is excused from the obligation to pay all or any part of the amount otherwise payable in respect of the Senior Indebtedness during the period subsequent to the commencement of such proceedings, the Holder agrees that all or such part of such amount shall be payable out of, and to that extent diminish and be at the expense of, the -5- Holder's reorganization dividends or other distributions in respect of any claim filed by it as a creditor or interest holder. In the event the holders of Senior Indebtedness receive amounts in excess of payment in full (in cash) of amounts outstanding in respect of Senior Indebtedness (without giving effect to whether claims in respect of the Senior Indebtedness are allowed in any insolvency proceeding), the holders of the Senior Indebtedness shall pay such excess amounts to the Holder. 7. Covenants. The Company covenants, so long as this Note shall be outstanding and unless the Holder shall otherwise consent in writing, that: (a) Financial Statements, Reports, etc. So long as this Convertible Note shall remain outstanding and the Company is subject to the filing requirements of Section 13(a), 13(c) or 15(d) of the Securities Exchange Act of 1934, as amended (the 'Exchange Act'), the Company will transmit or cause to be transmitted to Holder, promptly after the same are sent or become publicly available, copies of any and all financial statements and reports which are made available to its stockholders and all periodic and other reports, proxy statements, registration statements and other materials filed by it with the Securities and Exchange Commission, or any other governmental authority succeeding to any or all of the functions of said commission, or any national securities exchange, as the case may be.
