Purchase Agreement or to the extent that such representations and warranties expressly relate solely to an earlier date), unless the Borrowers are unable to remake and redate any such representation or warranty, in which case the Borrowers have
previously disclosed the same to the Agent and the Lenders in writing, and such inability does not constitute or give rise to an Event of Default; and (f) all schedules attached to the Note Purchase Agreement with respect to any particular
representation and warranty of the Borrowers set forth in the Note Purchase Agreement (as modified) remain true, accurate and complete, as updated in writing to the Agent as of the date of this First Amendment

be subject to, or an agreement by which the Borrowers are bound and which contains, a prohibition on further mortgaging or encumbering the same). The Borrowers hereby acknowledge and agree that the execution of this First Amendment by the Agent and
