12.4                        Independent Contractors.  The Parties each acknowledge that they shall be independent contractors and that the relationship among the Parties shall not constitute a partnership, joint venture, agency or any type of fiduciary relationship.  No Party shall have the authority to make any statements, representations or commitments of any kind, or to take any action, which shall be binding on any other Party, without the prior written consent of the other Parties to do so.

12.5                        Force Majeure. A Party shall be excused from the performance of its 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.  Such excuse shall be continued so long as the condition constituting force majeure continues and the nonperforming Party makes reasonable efforts to remove the condition.  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.  Notwithstanding the foregoing, a Party shall not be excused from making payments owed hereunder because of force majeure affecting such Party.

Pfizer shall have the right to permit an entity that is an Affiliate of Pfizer to perform any activity under this Agreement, including but not limited to the Packaging and Labeling, while such entity is an Affiliate of Pfizer, provided that the Affiliate shall perform such activities in compliance with the provisions of this Agreement, and provided further that such delegation shall not relieve Pfizer of its obligations under this Agreement.

12.7                        Severability.  Should one or more of the provisions of this Agreement become void or unenforceable as a matter of law, then such provision will be ineffective only to the extent of such prohibition or invalidity, without invalidating the remainder of this Agreement, and the Parties agree to substitute a valid and enforceable provision therefor which, as nearly as possible, achieves the desired economic effect and mutual understanding of the Parties under this Agreement.

12.8                        Waivers and Amendments.  The failure of any Party to assert a right hereunder or to insist upon compliance with any term or condition of this Agreement shall not constitute a waiver of that right or excuse a similar subsequent failure to perform any such term or condition by the other Party.  No waiver shall be effective unless it has been given in writing and signed by any Party giving such waiver.  No provision of this Agreement may be amended or modified other than by a written document signed by authorized representatives of each Party.

12.9                        Entire Agreement.  This Agreement and the Original Agreement, together with any schedules, exhibits or other attachments thereto, contain the entire agreement of the Parties with respect to the subject matter hereof, superseding all negotiations, prior discussions and preliminary agreements made prior to the date hereof.
