exercising any right will operate as a waiver of such right or any other right.

default by the other in the performance by the other of its obligations
hereunder will be deemed or construed to be a consent or waiver to or of any
other breach or default in the performance by such other party of the same or
any other obligations hereunder.

whether evidenced hereby, by any other document, or by law, will be cumulative
and may be exercised singularly or concurrently. Election by Secured Party to
pursue any remedy will not exclude pursuit of any other remedy, and an election
to make expenditures or take action to perform an obligation of Grantor under
this Agreement after Grantor's failure to perform will not affect Secured
Party's right to declare a default and exercise its remedies under Section 6
hereof or under any of the Loan Documents.

and inure to the benefit of the parties, their heirs, successors, and assigns.
