assets, to borrow money, to execute, deliver and perform each of the Loan Documents to
which it is a party and all other documents, certificates and instruments delivered in
connection therewith, and to effect and carry out the transactions contemplated herein

law, order, rule or regulation or determination of an arbitrator, court, or other
governmental agency, applicable upon the Borrower or any of the Borrowers property or
as to which the Borrower or any of the Borrowers property is subject, or (ii) any
provision of any agreement, instrument, or undertaking to which the Borrower is a
party or by which the Borrower or any of the Borrowers property is bound and will not
result in the creation or imposition of any lien upon any of the property of the
Borrower other than those in favor of the Lender pursuant to the Loan Documents. No
consents, approvals or other authorizations or notices, other than those which have
been obtained and are in full force and effect, are required in connection with the

contemplated thereby.2.2
