required in order to comply with deadlines under the law, it will not file
action or institute legal proceedings with respect to any dispute controversy
or claim arising out of, relating to, or in connection with, this Agreement,
until: (a) it has given the other Party written notice of its grievance; (b)

at any time performance by one or both of the other parties of the provisions
of this Agreement, will in no way be constructed to be a present or future
waiver of such provisions, nor in any way affect the ability of a party to
enforce each and every such provision thereafter.
