The Company will pay interest semi-annually on May 1 and November 1 of each year (each, an "Interest Payment Date"), commencing November 1, 1997. Interest on the Notes will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from May 20, 1997. Under certain circumstances, the Company shall be obligated to pay liquidated damages to the Holders, all as set forth in Section 2.18 of the Indenture. 2. Method of Payment. The Company shall pay interest on the Notes (except defaulted interest) to the Persons who are the registered Holders at the close of business on the Record Date immediately preceding the Interest Payment Date.

Except as provided below, the Company shall pay principal and interest in such coin or currency of the United States of America as at the time of payment shall be legal tender for payment of public and private debts ("U.S. Legal Tender"). However, the Company may pay principal and interest by wire transfer of Federal funds, or interest by its check payable in such U.S. Legal Tender. The Company may deliver any such interest payment to the Paying Agent or the Company may mail any such interest payment to a Holder at the Holder's registered address. 3. Paying Agent and Registrar. Initially, Fleet National Bank (the "Trustee") will act as Paying Agent and Registrar. The Company may change any Paying Agent, Registrar or co-Registrar without notice to the Holders. The Company or any of its Subsidiaries may, subject to certain exceptions, act as Paying Agent, Registrar or co-Registrar. 4. Indenture. The Company issued the Notes under an Indenture, dated as of May 20, 1997 (the "Indenture"), between the Company and the Trustee. Capitalized terms herein are used as defined in the Indenture unless otherwise defined herein. The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the TIA, as in effect on the date of the Indenture.

The Registrar need not register the transfer of or exchange any Notes selected for redemption. 8. Persons Deemed Owners. The registered Holder of a Note may be treated as the owner of it for all purposes. 9. Unclaimed Money. If money for the payment of principal or interest remains unclaimed for two years, the Trustee and the Paying Agent(s) will pay the money back to the Company at its written request. After that, all liability of the Trustee and such Paying Agent(s) with respect to such money shall cease. 10. Discharge Prior to Redemption or Maturity. If the Company at any time deposits into an irrevocable trust with the Trustee U.S. Legal Tender or Government Securities sufficient to pay the principal of and interest on the Notes to redemption or maturity and complies with the other provisions of the Indenture relating thereto, the Company will be discharged from certain provisions of the Indenture and the Notes (including the financial covenants, but excluding its obligation to pay the principal of and interest on the Notes). 11. Amendment; Supplement; Waiver.

Without notice to or consent of any Holder, the parties thereto may amend or supplement the Indenture or the Notes to, among other things, cure any ambiguity, defect or inconsistency, or make any other change that does not adversely affect the rights of any Holder of a Note. 12.

Change of Control. In the event there shall occur any Change of Control, each Holder of Notes shall have the right, at such Holder's option but subject to the limitations and conditions set forth in the Indenture, to require the Company to purchase on the Change of Control Payments Date in the manner specified in the Indenture, all or any part (in integral multiples of $1,000) of such Holder's Notes at a Change of Control Purchase Price equal to 101% of the principal amount thereof, together with accrued and unpaid interest, if any, to the Change of Control Payment Date. 14. Successors. When a successor assumes all the obligations of its predecessor under the Notes and the Indenture, the predecessor will be released from those obligations. 15. Defaults and Remedies.

Holders of Notes may not enforce the Indenture or the Notes except as provided in the Indenture. The Trustee may require indemnity satisfactory to it before it enforces the Indenture or the Notes. Subject to certain limitations, Holders of a majority in aggregate principal amount of the Notes then outstanding may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders of Notes notice of any continuing Default or Event of Default (except a Default in payment of principal, premium, if any, or interest, including a Default at any Maturity Date), if it determines that withholding notice is their interest. 16. No Recourse Against Others. No stockholder, director, officer, employee or incorporator, as such, past, present or future, of any obligor under the Notes or any successor corporation shall have any liability for any obligation of any obligor under the Notes or the Indenture or for any claim based on, in respect of or by reason of, such obligations or their creation.
