understandings between the Parties with respect to the subject matter hereof (including the Prior Agreement). There are no covenants, promises, agreements, warranties, representations, conditions or understandings, either oral or written, between the Parties other than as are set forth in this Agreement. For the avoidance of doubt, the Parties agree that neither has any obligations under the Prior Agreement, which is hereby terminated in its entirety and superseded by the terms and conditions hereof. After the Effective Date, neither Party shall make any claim or demand whatsoever against the other Party or any of its officers, directors, shareholders, agents, employees, subsidiaries and Affiliates (each a “Released Party” and together the “Released Parties”) with respect to the Prior Agreement, and each Party hereby irrevocably and forever releases all such Released Parties from any and all liabilities, demands, claims (including third Party claims), costs, losses, damages and expenses (including, without limitation, interest, penalties and attorney fees), known or unknown, contingent or otherwise, which such releasing Party may otherwise have against or recover from such Released Parties under the Prior Agreement, except as resulted from fraud, gross negligence or intentional misconduct by a Released Party. Amendments or changes to this Agreement shall be valid and binding only if in writing and signed by duly authorized representatives of the Parties.

14.2Force Majeure. Both Parties shall be excused from the performance of their obligations under this Agreement to the extent that such performance is prevented by force majeure and the nonperforming Party promptly provides notice of the prevention to the other Party.

For purposes of this Agreement, force majeure shall include conditions beyond the control of the Parties, including an act of God, war, civil commotion, terrorist act, labor strike or lock-out, epidemic, failure or default of public utilities or common carriers, destruction of production facilities or materials by fire, earthquake, storm or like catastrophe, and failure of plant or machinery (provided that such failure could not have been prevented by the exercise of skill, diligence, and prudence that would be reasonably and ordinarily expected from a skilled and experienced person engaged in the same type of undertaking under the same or similar circumstances). Notwithstanding the foregoing, a Party shall not be excused from making payments owed hereunder because of a force majeure affecting such Party. If a force majeure persists for more than [* * *], then the Parties shall discuss in good faith the modification of the Parties’ obligations under this Agreement in order to mitigate the delays caused by such force majeure.

14.8Severability. If any provision of this Agreement is found by a court of competent jurisdiction to be unenforceable, then such provision shall be construed, to the extent feasible, so as to render the provision enforceable, and if no feasible interpretation would save such provision, it shall be severed from the remainder of this Agreement. The remainder of this Agreement shall remain in full force and effect, unless the severed provision is essential and material to the rights or benefits received by either Party. In such event, the Parties shall negotiate, in good faith, and substitute a valid and enforceable provision or agreement that most nearly implements the Parties’ intent in entering into this Agreement.

14.9No Waiver. No provision of this Agreement can be waived except by the express written consent of the Party waiving compliance. Except as specifically provided for herein, the waiver from time to time by either Party of any of its rights or its failure to exercise any remedy shall not operate or be construed as a continuing waiver of same or of any other of such Party’s rights or remedies provided in this Agreement.
