breached or defaulted in the performance of any of its material obligations
hereunder, the other Party may terminate this Agreement in accordance with this
Section 12.2.&#160; The non-breaching Party
shall provide written notice to the other Party of its material breach or
default in the performance of any of its material obligations.&#160; If the Party receiving such notice disputes
that the non-breaching Party is entitled to terminate this Agreement under this
Section 12.2.1 (including, without limitation, whether a breach or default
occurred or whether such breach or default was material), then the matter shall
be referred to binding arbitration pursuant to Section 12.2.2 below.&#160; Any permitted termination shall become
effective (a) if no arbitration occurs, ninety&nbsp;(90) days after the
effective date of such notice, (b) if arbitration is resolved in favor of the
non-breaching Party, ninety&nbsp;(90) days after the arbitrator&#146;s ruling,
unless, in either case, the breaching Party (or any other party on its behalf)
has cured any such breach or default prior to the expiration of the
ninety&nbsp;(90) day period.&#160;
Notwithstanding the foregoing, in the event of a failure to perform a
material obligation under this Agreement that is capable of being cured, but is
not reasonably capable of being cured within the ninety (90) day cure period,
provided that (i) the breaching Party proposes within such ninety (90) day
period a written plan to cure such non-performance within a defined time frame,
(ii) such written plan and timeframe are reasonably acceptable to the
non-breaching Party, and (iii) the breaching Party makes good faith efforts to
cure such default and to implement such written cure plan, then the
non-breaching Party may not terminate this Agreement for so long as the
breaching Party is diligently pursuing such cure; provided, however, that the
breaching Party shall lose its right to continue to cure pursuant to this
sentence if at any time such Party ceases to make a good faith effort to cure
such default for a period exceeding fourteen (14) days during the extended cure
period or if such Party fails to cure such default within the defined time
frame, and in such case the notifying Party shall have the right to terminate
immediately on written notice to the breaching Party.&#160; The right of either Party to terminate this
Agreement as herein above provided shall not be affected in any way by its
waiver of, or failure to take action with respect to, any previous default or
non-performance.</font></h3>
