(d) The execution, delivery and performance of this First Amendment and the First Allonges will not violate any applicable provision of law or judgment, order or regulation of any court or of any public or governmental agency or authority nor conflict with or constitute a breach of or a default under any instrument to which the Borrower is a party or by which the Borrower or the Borrower's properties are bound nor result in the creation of any lien, charge or encumbrance upon any assets of the Borrower. (e) No approval, consent or authorization of, or registration, declaration or filing with, any governmental or public body or authority is required in connection with the valid execution, delivery and performance by the Borrower of this First Amendment and the First Allonges. 5.
