  NEW CHIEF FINANCIAL OFFICER AND HEAD OF HUMAN RESOURCES**

NEW YORK, February 24 - Pfizer Inc today announced that three senior
  leaders - Karen Katen, Jeff Kindler and David Shedlarz – will each become
  a vice chairman of Pfizer Inc and join Chairman and Chief Executive Officer
  Hank McKinnell on the newly formed Pfizer Executive Committee. 
  The appointments, effective March 3, were approved today by the Board of Directors.
  The three executives will continue to report to Dr. McKinnell. The Pfizer Executive
  Committee will be responsible for the strategic direction and operations of
  the company.
  “Today’s promotions reflect both the outstanding capabilities of
  these Pfizer leaders and our commitment to move quickly to streamline decision-making,”
  said Dr. McKinnell. “Responding to the challenges in our operating environment
  demands that we leverage our competitive strengths, execute flawlessly and sustain
  the values that have made this company a world leader in health. Karen, Jeff
  and David personify the best of Pfizer, and I join with their colleagues in
  congratulating them on their well-deserved promotions.”
  Ms. Katen, formerly president of Pfizer Global Pharmaceuticals, was named president
  of Pfizer Human Health, the global operating group encompassing drug discovery
  and development, manufacturing, distribution and commercialization. Ms. Katen
  joined Pfizer in 1974 in marketing after receiving her M.B.A. from the University
  of Chicago.
  John LaMattina, Ph.D., senior vice president and president of Pfizer Global
  Research and Development; Peter Corr, Ph.D., senior vice president, Science
  and Technology; and Nat Ricciardi, senior vice president and president, Pfizer
  Global Manufacturing, will now report to Ms. Katen. Joe Feczko, MD, president,
  Worldwide Development, who currently reports to both Ms. Katen and Dr. LaMattina,
  will serve as Pfizer’s chief medical officer.
  Mr. Kindler, who oversees the company’s legal affairs worldwide and serves
  as general counsel, will also assume management responsibility for Corporate
  Affairs, the division charged with government relations, communications, corporate
  citizenship, philanthropy, policy analysis and related activities. Members of
  this division work to ensure that the value of medicines and importance of biomedical
  innovation are communicated to the public, policymakers and other key audiences.
  Mr. Kindler joined Pfizer in 2002 from McDonald’s Corporation, where he
  was president of Partner Brands. At McDonald’s, he also served as executive
  vice president, Corporate Relations, and general counsel. Mr. Kindler graduated
  in 1980 from Harvard Law School. 
  Chuck Hardwick, senior vice president, Corporate Affairs, had previously announced
  his intention to retire. Mr. Hardwick, who is in his 40th year at Pfizer, was
  instrumental in building Pfizer’s state and federal government relations
  team, as well as managing the company’s global philanthropy and communications
  functions.

Mr. Shedlarz, who oversees operations including finance, strategic planning,
  global sourcing and information systems, will also take on responsibility for
  Pfizer Human Resources. 
  Pfizer Human Resources is charged with sustaining Pfizer as a globally respected
  employer, implementing global HR initiatives that improve business competitiveness,
  and ensuring the ongoing development of Pfizer’s talent. Mr. Shedlarz
  joined Pfizer in 1976 as a financial analyst and holds an M.B.A. from New York
  University.
  With his promotion to Vice Chairman, Mr. Shedlarz will end his tenure as chief
  financial officer, a position he has held since 1995. Alan Levin has been appointed
  a Pfizer Inc senior vice president and named chief financial officer, reporting
  to Mr. Shedlarz. Mr. Levin, a CPA, joined Pfizer in 1987 after earning his MS
  in accounting from NYU.

  the company, has been appointed as Pfizer’s senior vice president, Human
  Resources, reporting to Mr. Shedlarz.
