This Note shall be pari passu and shall not be subordinated in right of payment to the notes issued by the Borrower to Mitchell P. Rales and Steven M. Rales, bearing the registration numbers R-1, R-2, R-3, R-5, and R-6. For purposes of this Section 2: "Insolvency or Liquidation Proceeding" means (i) any insolvency or bankruptcy case or proceeding, of any receivership, liquidation, reorganization or other similar case or proceeding in connection therewith, relating to the Borrower or its assets, or (ii) any liquidation, dissolution or other winding up of the Borrower, whether voluntary or involuntary or whether or not involving insolvency or bankruptcy, or (iii) any assignment for the benefit of creditors or any other marshaling of assets or liabilities of the Borrower. "Post-Petition Interest" means all interest accrued or accruing after the commencement of any Insolvency or Liquidation Proceeding (and interest that would accrue but for the commencement of any Insolvency or Liquidation Proceeding) in accordance with and at the contract rate (including, without limitation, any rate applicable upon default) specified in the agreement or instrument creating, evidencing or governing any indebtedness, whether or not, pursuant to applicable law or otherwise, the claim for such interest is allowed as a claim in such Insolvency or Liquidation Proceeding. (a) Liquidation; Dissolution; Bankruptcy. Upon any distribution or payment to creditors of the Borrower in a liquidation, dissolution, winding up or reorganization of the Borrower of any kind or character and whether voluntary or involuntary or in a bankruptcy, reorganization, insolvency, receivership or similar proceeding relating to the Borrower, its property or to its creditors as such or in an assignment for the benefit of creditors or any marshaling of the assets and liabilities of the Borrower: (i) the holder of the Senior Debt shall be entitled to receive indefeasible payment in full (where used in this Note, "in full" shall mean the indefeasible payment in cash in full of all amounts owing to the holders of Senior Debt) of all amounts owing with respect to the Senior Debt (including, without limitation, interest and expenses accrued after the occurrence of any such event or the commencement of any such proceeding at the rate specified in the Senior Debt regardless of whether or not such interest is allowable as a bankruptcy claim in such proceeding) before the registered holder shall be entitled to receive, 3 4 CONFORMED COPY directly or indirectly, any payment of or distribution with respect to principal, premium, if any, or interest on this Note; and (ii) until the Senior Debt is paid in full, any payment or distribution to which the registered holder would be entitled but for these subordination provisions shall be made to the holder of the Senior Debt, as its interest may appear, except that the registered holder may receive securities that are subordinated to at least the same extent as this Note to the Senior Debt. (b) Default on Senior Debt. So long as a default in the payment of any Senior Debt exists and is continuing, the Borrower may not pay principal of, premium, if any, or cash interest on this Note and may not repurchase, redeem or otherwise retire this Note (collectively, "pay this Note"), and the registered holder agrees that it shall not ask, demand or sue for, or take or receive from Borrower, directly or indirectly, in cash, securities or other property or by way of set-off, any payment of this Note, subject to the terms of the Senior Debt. (c) When Distribution Must Be Paid Over. In the event that a pay ment or distribution is made to the registered holder at a time when such payment or distribution is prohibited by paragraphs (a) and (b) hereof, the registered holder who receives the payment or distribution shall hold it in trust for the benefit of, and promptly pay it over (in the same form as received but with any necessary endorsements) to, the holder of the Senior Debt as its interest may appear, or its agent or representative or the trustee under the indenture or other agreement (if any) pursuant to which the Senior Debt may have been issued, as their respective interests may appear, for application to the payment of all obligations with respect to the Senior Debt remaining unpaid to the extent necessary to pay such obligations in full in accordance with their terms, after giving effect to any concurrent payment or distribution to or for the holder of the Senior Debt. (d) Notice by the Borrower. The Borrower shall promptly notify the registered holder in writing of any facts known to the Borrower that would cause a payment of any amounts with respect to this Note to violate the provisions hereof, but failure to give such notice shall not affect the subordination of this Note to the Senior Debt. (e) Subrogation. After all Senior Debt is indefeasibly paid in full in cash for a period of time in excess of all applicable preference or similar periods under applicable bankruptcy, insolvency or creditors' rights laws, and until this Note is paid in full, the registered holder shall be subrogated (equally and ratably with all other debt that 4 5 CONFORMED COPY is pari passu with this Note) to the rights of the holder of the Senior Debt to receive distributions applicable to the Senior Debt to the extent that distributions otherwise payable to the registered holder have been applied to the payment of Senior Debt. A distribution made under the subordination provisions of this Note to the holder of the Senior Debt which otherwise would have been made to the registered holder is not, as between the Borrower and the registered holder, a payment by the Borrower on this Note. (f) Relative Rights. This Note defines the relative rights of the registered holder and the holder of the Senior Debt. Nothing in this Note shall: (i) impair, as between the Borrower and the registered holder, the obligation of the Borrower, which is absolute and unconditional, to pay principal of and interest on this Note in accordance with its terms; (ii) affect the relative rights of the registered holder and creditors of the Borrower other than their rights in relation to the holder of the Senior Debt; or (iii) prevent the registered holder from exercising any available remedies, subject to the rights of the holder of the Senior Debt to receive distributions and payments otherwise payable to the registered holder. (g) Subordination May Not Be Impaired. No right of any present or future holder of Senior Debt to enforce the subordination of the obligations with respect to this Note shall be prejudiced or impaired by any act or failure to act by the Borrower or by any act or failure to act or waiver of any terms of this Note, by any such holder, or by any noncompliance by the Borrower with the terms of the subordination provisions of this Note, regardless of any knowledge thereof which any such holder may have or be otherwise charged with. The holder of the Senior Debt may extend, renew, modify or amend the terms of the Senior Debt or any security therefor and release, sell or exchange such security and otherwise deal freely with the Borrower, all without the consent of or notice to, and without affecting the liabilities and obligations of, the Borrower or the registered holder. No provision in any supplemental agreement or document which modifies the subordination provisions of this Note or otherwise affects the superior position of the holder of the Senior Debt shall be effective against the holder of the Senior Debt if such holder has not consented thereto in accordance with the provisions of the document governing such Senior Debt. 5 6 CONFORMED COPY (h) The Registered Holder Entitled to Rely. Upon any payment or distribution pursuant to these subordination provisions, the registered holder shall be entitled to rely (i) upon any order or decree of a court of competent jurisdiction in which any proceedings of the nature referred to in paragraph (a) above are pending, (ii) upon a certificate of the liquidating trustee or agent or other person making such payment or distribution to the registered holder or (iii) upon the representatives for the holder of the Senior Debt for the purpose of ascertaining the persons entitled to participate in such payment or distribution, the holder of the Senior Debt and other indebtedness of the Borrower, the amount thereof or payable thereon, the amount or amounts paid or distributed thereon and all other facts pertinent thereto or to the subordination provisions of this Note. (i) Reliance by the Holder of the Senior Debt on Subordination Provisions. The registered holder, by accepting this Note, acknowledges and agrees that the foregoing subordination provisions are, and are intended to be, an inducement and a consideration to the holder of the Senior Debt, whether such Senior Debt was created or acquired before or after the issuance of this Note, to acquire and continue to hold, or to continue to hold, such Senior Debt, and such holder of Senior Debt shall be deemed conclusively to have relied on such subordination provisions in acquiring and continuing to hold, or in continuing to hold, such Senior Debt. These subordination provisions are intended to be for the benefit of, and shall be enforceable directly by, the holder of the Senior Debt. The registered holder hereby waives to the fullest extent permitted by law any right to compel marshaling or to otherwise seek to compel the holder of the Senior Debt to follow any particular order of realization upon any collateral for or any particular order or manner of enforcement of remedies with respect to the Senior Debt. 3.

Each such new Note shall be payable to such Person as such holder may request and shall be substantially in the form of this Note. Each such new Note shall be dated and bear interest from the date to which interest shall have been paid on the surrendered Note or dated the date of the surrendered Note if no interest shall have been paid thereon.
