The definition of Manufacturing Facility Completion in Section 4.1(b) of the Agreement shall include issuance of all permits required for the installation of the Manufacturing Equipment.

3.4 Force Majeure

Section 19.5 of the Agreement is deleted and replaced by the following:

If either Party is rendered wholly or partially unable by Force Majeure to carry out its obligations under this Agreement, and if that Party gives prompt written notice, including a reasonable description of such Force Majeure, to the other Party, the notifying Party shall be excused from performance of its obligations hereunder during the continuance of any inability so caused, but for no longer period. Such cause shall be remedied by the notifying Party as far as possible with reasonable speed and effort, but neither Party shall have any obligation to settle any labor dispute. For the purposes of this Agreement, “Force Majeure” shall mean Acts of God, labor disputes, acts of public enemies or terrorists, war, other military conflicts, blockades, insurrections, riots, epidemics, quarantine restrictions, landslides, lightning, earthquake, fires, conflagration, storms, floods, washouts, arrests, civil disturbances, restraints by or actions of any governmental body (including export or security restrictions on information, material, personnel, equipment or other changes in laws), changes in federal, state or municipal regulation or policy that materially and adversely affect the business of SILEVO (collectively for this purpose with its parent corporation and affiliates) (including, without limitation, significant increases in tariffs or duties relating to components necessary for the operation of the Manufacturing Facility), industry-wide shortages, industry-wide unavailability, and any other acts or events whatsoever, whether or not similar to the foregoing, not within the control of the Party claiming excuse from performance, which by the exercise of the diligence and reasonable efforts that Party shall not have been able to overcome or

avoid. If the notifying Party cannot remedy the Force Majeure situation and resume satisfactory performance within ninety (90) days after delivery of the notice, the other Party may at their option immediately terminate this Agreement and such notifying Party will be treated as a Terminated Party under Section 11.4 hereof; provided such time limit shall not apply to SILEVO’s inability to perform its obligations under Section IV and Exhibit G.
