Guarantor may terminate this Guaranty by providing written notice of such termination to ECT and upon the effectiveness of such termination, Guarantor shall have no further liability hereunder, except as provided in the last sentence of this paragraph. No such termination by Guarantor shall be effective until five (5) days after receipt by ECT of such termination notice. No termination of this Guaranty pursuant to the provisions of this paragraph shall affect Guarantor's liability with respect to any Transaction (as defined in the Contracts) entered into prior to the Termination Date, which Transaction shall remain guaranteed pursuant to the terms of this Guaranty."
