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. 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. 6 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.
