Arrangement (other than the Credit Documents and the Other NEG Guarantees) that contains a NEG Downgrade Event Provision that results in such Equity Funding Arrangement (taken as a whole with its related credit documents) being materially more favorable to the lenders and/or investors thereunder than this Guaranty and Agreement is to the Secured Parties.
