China. The services described below are related to the provision of * screening services and include *. 
  

	2.	WuXi PharmaTech SERVICES 

 Both Pfizer and you
acknowledge that there are considerable uncertainties with respect to the duration, scope and operation of the * Pilot that may require the Pilot to be expanded, reduced, extended, terminated or otherwise adjusted. Accordingly, a Steering
Committee will be established with at least two representatives from each company to meet regularly (at least monthly) to review and discuss the progress of the Pilot and your services and make any adjustments that may be needed (including the start
and end dates, processes and procedures, capacity and pricing). 
 WuXi PharmaTech will perform the * screening for the *
Pilot. This * will require you to establish a * Assay and a * Assay as described below, dedicate certain FTEs and Bioanalytical equipment as described below, and screen the number of samples required by the protocols
referred to below for up to * compounds per week. Initially, Pfizer will direct to you all the compounds for * screening from a single Pfizer * project. Given inherent uncertainties in the conduct of * projects the number
of compounds directed to you for screening on week to week basis will vary. It is estimated that the weekly requirements for compounds screening will range from * compounds. 
 It is anticipated that your screening will commence by March 15, 2007 and that your support of the * Pilot will last 3 to 6 months. Before the
end of the first 3 months after your screening has commenced the Steering Committee will meet to conduct a detailed review of the Pilot and to determine whether the Pilot will be extended for an additional three months or such other period as the
parties agree. 
 If, on conclusion of the * Pilot, Pfizer decides to proceed with the sourcing of * services in China, Pfizer and you will negotiate in good faith to establish a longer term contract for the routine
supply of these services that will address capacity commitments and other operational matters to reflect the parties’ learnings from the Pilot. Longer term contract pricing will be set per Appendix B, Section 5.
