In the past, conversations have taken place between representatives of American Commercial Terminals, Inc. (ACT, fomerly ACBL Western, Inc. (ACBL), Burlington Northern (BN), and the City of St. Louis (City). One topic of particular discussion has been the approximately 70 acres, the site of the coal transfer facility, owned by ACT. The City has indicated its interest in reserving for future development that part of the property which lies south of the extension of Adelaide Avenue and ACT is willing to do so in consideration of the granting of a lease on certain adjacent riverfront property to be used in conjunction with its bulk commodity transfer facility. ACT hereby grants onto the City of St. Louis the following interests in said property lying south of the extension of Adelaide: -2- (A) For a period of 10 years from the date hereof, the right to first refusal to acquire said property or to designate another party to acquire said property, provided that the purpose of acquisition is for industrial development on a firm basis. In such event, the party seeking to develop the property must have a firm construction contract acceptable to the City to permit completion and commencement of operation of the improvement within a reasonable time. ACT shall have the right to refuse to transfer the property for such purpose only if the proposed activity would compete with or would substantially interfere with ACT's operation of its bulk commodity transfer facility or with BN's rail common carrier activities. (B) The above mentioned right of first refusal shall lapse in the event that ACT shall indicate in writing to the City that ACT wishes to expand the capacity of its bulk commodity transfer facility by use of such property, or to otherwise develop such property, and if the City within 180 days thereafter does not exercise such right of first refusal. ACT may not, however, indicate such a desire to utilize such property until at least 3 years from date hereof. (C) In the event such right of first refusal is exercised, the transferee shall pay to ACT for such property the prorated per acre price paid By ACT for the entire tract plus an interest charge from the date July 1, 1975, until the date of transfer. The interest charge shall be calculated (1) by applying the prime interest rate charged by Chase Manhattan Bank on a monthly basis, plus 1/2 of it, or (2) at a rate of 10% per annum, whichever is less. 7. The following shall be added after the first sentence of Paragraph 5 of Appendix A hereto; "The term "cure" as used herein with respect to providing the Lessee ninety days of the notice of any default other than non-payment in which to cure such default, shall mean prompt institution of all proceedings and actions necessary to accomplish such -3- cure and the diligent pursuit thereof. The Lessor shall take no action to cancel such lease rights based upon such a default other than for non-payment so long as all proceedings and actions necessary to such a cure have been and are promptly instituted and diligently pursued; provided that in no event, other than due to an occurrence of an act of God or other event outside of the control of Lessee, shall such cure period be for longer than ??? days after such notice." 8. The following shall be added at the end of Paragraph 9 of Appendix A hereto: "In the event the Lessor should exercise its rights under Paragraphs 8 and 9 of Appendix A, it is the intent of the Lessor and the Lessor will make every effort to provide to Lessee or its approved successor, an appropriate and acceptable site for mooring vessels if desired by Lessee consistent with any leases or other agreements which may be in effect at that time. The Lessor recognizes the magnitude of the investment made by Lessee and the vital significance of Lessee's location hereunder as a part of its business." 9. The following shall be added at the end of Paragraph 13 of Appendix hereto: "Notwithstanding the foregoing, the Lessee is hereby authorized to assign the lease or sublease the property leased hereby to the Bi-State Development Agency of the Missouri-Illinois Metropolitan District ("Bi-State") and for Bi-State to assign or sublease said property back to Lessee, including pursuant to the lease between Lessee and Bi-State dated June 30, 1980 and the sublease agreement between Bi-State and Lessee dated as of june 30, 1980, all in connection with the $23,000,000 aggregate principal amount of district Terminal Facilities revenue Bonds (American Commercial Terminals, Inc., Project), Series 1980 of Bi-State issued on or about June 30, 1980 and any refunding bonds issued to pay off all or a portion of said bonds hereafter. Any approved assignee or sublease is granted rights of notice and cure of default in addition to, and to the same extent as, the Lessee hereunder." -4- 10. The second sub-paragraph of Paragraph 14 of Appendix A is hereby deleted and the following is substituted therefor: "Sale of all or substantially all of the assets of the Lessee other than to or by Bi-State or the trustee for the bondholder in connection with the bond issue or any refunding bond issue referred to in Paragraph 7 of this lease, or transfer of the lease by the Lessee, without Board of Public Service and Port Commission approval makes this lease subject to cancellation at the option of the Lessor." 11.

Landlord will not assert, and therefore waives, any liens, whether granted by the Lease, statute or otherwise (including, without limitation, rights of levy or distraint for rent), against the property of Tenant located on the Premises, including, without limitation, Tenant's machinery, improvements, equipment, furniture, fixtures, inventory and all additions, replacements or substitutions therefor (collectively, the "PERSONAL PROPERTY"). 8. If Tenant defaults on its obligations to NRG and, as a result, NRG exercises its rights under the Assignment, or otherwise undertakes to enforce its security interest in Tenant's assets, Landlord will permit NRG or its agent to enter and take possession of the Premises without terminating the Lease, and Landlord will recognize NRG (or other nominee thereof) as the tenant under the Lease, entitled to all of the benefits thereof, and responsible for the performance of all of Tenant's obligations arising thereunder from and after the date that NRG takes possession as aforesaid. NRG may cause the Premises to be assigned or sublet with the written consent of Landlord, which consent shall not be unreasonably withheld, provided, however, that Landlord agrees that it will consent to an assignment to any subsidiary or affiliate of NRG and that NRG has the right to transfer its interest in the Lease, with notice but without consent, to an entity controlled by, controlling or under common control with NRG, or to a business entity which acquires all or substantially all of the assets of NRG. It is understood and agreed that any consent by Landlord to any assignment or subletting by NRG shall not be considered or construed to be a consent to any subsequent assignment or subletting nor as a waiver of the right of Landlord to refuse to consent to any subsequent assignment or subletting. 9. In accordance with and subject to the terms of the Deed of Trust from Tenant to LG and NRG (the "DOT"), NRG may, at no expense to Landlord enter onto the Premises following a Trigger Event and take possession of, sever, or remove the Personal Property or any part thereof, and said Personal Property, upon severance and/or removal, may be sold, transferred or otherwise disposed of free and discharged of all liens, claims, demands, rights or interests of Landlord. If NRG and/or LG enters the Premises solely for the purposes of executing such party's rights with respect to the Personal Property under the DOT, (i) NRG shall not be deemed to have assumed any obligations or liabilities of Tenant under the Lease merely by reason of such limited purpose entrance, and (ii) NRG shall not have any duty or obligation to remove or dispose of any remaining Personal Property left on the Premises following such removal; provided that NRG agrees to repair any damage to the Premises caused by the removal of such Personal Property. 7 10. Landlord: (a) will use commercially reasonable efforts to give copies of all notices of default sent to Tenant under the Lease to NRG at: NRG New Roads Holdings LLC 112 Telly Street New Roads, LA 70760 or to such other address as NRG may designate from time to time by notice given to Landlord at the address set forth after its signature hereto, and (b) prior to exercising any of Landlord's rights and remedies under the Lease or at law or in equity, NRG shall have the right (but not the obligation) to cure or cause to be cured such default within the following time periods from and after receipt by NRG of notice of such default from Landlord: ten (10) days with respect to monetary defaults and thirty (30) days with respect to non-monetary defaults after the period of time granted to Tenant to cure such defaults under the terms of the Lease; provided, however, that if the nature of any non-monetary default is such that the same cannot be cured within said thirty (30) day period, NRG shall be given such additional period of time as may be necessary to cure the default provided that NRG commences the cure within said thirty (30) day period and proceeds diligently thereafter to complete such cure. 11. Landlord will not consent to any material amendment, supplement or other material modification of the Lease without NRG's prior written consent, which consent shall not be unreasonably withheld. 12. Landlord agrees to disclose this Landlord Consent to any purchaser or successor to Landlord's interest in the Premises. 13. The statements and agreements contained herein shall be binding upon, and shall inure to the benefit of, NRG, its affiliates, Tenant and its affiliates, successors and assigns, Landlord, mortgagees of the Premises and the successors and assigns of all of the foregoing. 14. Notwithstanding anything herein to the contrary, nothing in this Consent nor in the Assignment shall be deemed to enlarge Tenant's or NRG's rights or privileges under the Lease, or to diminish Tenant's or NRG's obligations or liabilities under the Lease.
