Repayment Terms. NBI shall repay the Remaining Principal Amount --------------- in two installments: (a) on or before December 31, 1998, NBI shall pay the IRS the sum of $3,500,000.00, and (b) on or before December 31, 1999, NBI shall pay the IRS the remaining $1,778,000.00. Upon satisfying such payments, the Remaining Principal Amount shall be deemed satisfied in full. NBI may prepay all or any portion of the Remaining Principal Amount at any time without premium or penalty. NBI agrees to remit the $3,500,000.00 payment to the IRS as soon as practicable after such amount becomes available to NBI, but in no event later than December 31, 1998. 2. Collateral. NBI owns all the capital stock of American Glass, ---------- Inc. d/b/a L.E. Smith Glass Company, a glass products manufacturer located in Mount Pleasant, Pennsylvania ("American Glass"). NBI also owns all of the capital stock of NBI Properties, Inc. f/k/a Belle Vernon Motel Corporation which owns and operates the Belle Vernon Holiday Inn located in Belle Vernon, Pennsylvania ("NBI Properties"). Pursuant to a Pledge Agreement dated as of March 19, 1996 which was executed in connection with the Original Agreement, NBI granted the IRS a valid first security interest in all the capital stock of American Glass and NBI Properties to secure the obligations under the Original Agreement, as evidenced by the related physical stock certificates, which have previously been delivered to the IRS. The capital stock of American Glass and NBI Properties shall similarly secure the obligations of NBI to the IRS under this Agreement. Upon the full payment of the Remaining Principal Amount, the Pledge Agreement and the IRS security interest in the capital stock of American Glass and NBI Properties will terminate and such stock certificates shall be returned to NBI. 3. Default Provisions. In the event of a failure of NBI to make any ------------------ payment provided in paragraph 1. hereof, an event of default shall have occurred fifteen (15) days after written notice and demand from IRS to NBI in respect of such payment unless NBI has previously (a) cured the default by payment of the amount due, or (b) given written notice to IRS that it disputes the existence of the default with a recitation of the reasons why, with supporting documentation. In the event of a failure of NBI to take any other action required by this Agreement, an event of default shall have occurred thirty (30) days after written notice and demand from IRS to NBI in respect of such failure unless NBI had previously (a) cured the default, or (b) given written notice to IRS that it disputes the existence of the default with a recitation of the reasons why, with supporting documentation. In the event of a continuing event of default, IRS may by written notice to NBI declare the Remaining Principal Amount due and payable and interest thereon at the statutory rate provided under the Internal Revenue Code since the last interest payment made by NBI under the Original Agreement, and the IRS shall be entitled to pursue its remedies. Nothing herein shall limit the rights and remedies of the IRS or NBI with respect to post-effective date taxes. In the event of a dispute over the existence of an event of default and the inability of the parties to resolve such a dispute within twenty (20) days after NBI gives written notice that such dispute exists, the parties jointly or separately must submit the dispute to the United States Bankruptcy Court for the District of Colorado for adjudication within fifteen (15) days of the expiration of the twenty (20) day resolution period. Such submission will not relieve the parties of any continuing obligation under this Agreement which might arise following such submission unless such obligation is the subject of the dispute. Failure of the party disputing the existence of an event of default to make such submission to the court within the referenced time period will constitute an admission of default and trigger the remedies available. In the event NBI incurs undisputed post-petition Federal Tax Liabilities, an event of default under this Agreement shall have occurred fifteen (15) days after written notice and demand from IRS to NBI for payment of such undisputed liabilities unless NBI has previously (a) paid the undisputed liability, with undisputed interest and penalties, if any, or (b) given written notice to IRS that it disputes the existence of the default, with a recitation of the reasons why, with supporting documentation. In the case of an event of default or a dispute, the provisions of the preceding paragraph shall apply. 4.
