TRANSITION TEAM LEADERS FROM PFIZER AND PHARMACIA GATHER FOR FIRST MEETING

x--------------------------------x     Pharmacia CFO Chris Coughlin (standing)
|                                |     participates in a breakout session at the
|                                |     first meeting of transition team leaders.
|                                |
|                                |     -----------------------
|                                |
|                                |     From the outset, top leaders from Pfizer
|                                |     and Pharmacia have said that the
|           [GRAPHIC]            |     transition planning process -- which will
|                                |     take place between now and the close of
|  Transition team hard at work  |     the deal -- and the subsequent
|                                |     integration of our two companies, will be
|                                |     largely driven by our businesses and
|                                |     divisions, rather than Corporate. Toward
|                                |     that end, two transition team leaders
|                                |     have been named for each of our major
|                                |     businesses and divisions -- one from
|                                |     Pfizer, one from Pharmacia. These
|                                |     colleagues are responsible for the
|                                |     day-to-day transition planning process
|                                |     and for ensuring that their
|                                |     business/division is ready for Day One.
|                                |     They met as a group for the first time
|                                |     Tuesday, August 13, at the Millennium
x--------------------------------x     Broadway Hotel in New York.

Pfizer's Chief Financial Officer David Shedlarz, who is leading the transition
process for Pfizer, opened the meeting by thanking the transition team leaders
for their participation and saying that he was "very favorably impressed with
how well the two companies were working together" since before the deal was even
announced.

"You have an awesome responsibility," Shedlarz told the transition team leaders.
"You are on the front lines of bringing together two large, complex, and
fast-growing companies."

Shedlarz shared a number of guiding principles for the transition: moving with
clarity and speed; adhering to the values and behaviors of both companies,
especially Respect for People; and ensuring alignment across both organizations,
and within each individual company.

Shedlarz expressed his concern that most colleagues currently view the
acquisition as being primarily driven by cost cutting opportunities. While the
deal will, indeed, yield significant synergies, Shedlarz emphasized a host of
other reasons why this is the right move for Pfizer:

     o    An unequaled pharmaceutical product portfolio
     o    A broader and deeper R&D pipeline
     o    Stronger animal health and consumer healthcare businesses
     o    Greater, more balanced geographic presence
     o    Enhanced scale, with less reliance on any one product
     o    Greater operating flexibility and ability to manage risk

Chris Coughlin, Pharmacia's CFO and the leader of the transition process for
Pharmacia, said that both companies have a wealth of experience with mergers and
acquisitions. Still, he cautioned, "we can't underestimate the size and
complexity of the task at hand."




Coughlin reminded the attendees to pay particularly close attention to how the
transition planning process is progressing in markets outside the United States,
which often get overlooked because the U.S. market is so large for both
companies.

Coughlin said that Pharmacia is "absolutely committed to ensuring the smoothest
and best transition possible." He stated clearly that all major decisions during
the transition planning process and beyond will ultimately be made by the Pfizer
Leadership Team, with input from Pharmacia. He added that Pfizer systems will be
used in the combined company, unless there is a clear and compelling reason to
do otherwise.

Like Shedlarz, Coughlin noted that the relationships between Pfizer and
Pharmacia colleagues have been excellent thus far, even through some "difficult
and intense times."

Coughlin also echoed Shedlarz's view that the transition team leaders are
shouldering a very significant responsibility. "You're going to have access to
sensitive information that no one else knows," he said. "And you're going to
have to keep it that way until final decisions have been made and communicated."

Coughlin emphasized that, while the overall goal is to complete the acquisition
as soon as possible, "different transition teams will move at different speeds."
In general, though, he said it is "OK to go a little too fast."

LESSONS LEARNED, CULTURES SHARED

Joe Bonito, vice president, Worldwide Organizational Effectiveness, PPG [Pfizer
Pharmaceuticals Group], and a member of the Program Office that has been
established as a central resource for the transition teams to call upon, shared
lessons learned from the Pfizer/Warner-Lambert combination, completed just over
two years ago. These include the need to focus on speed, to communicate rapidly,
to drive decisions through the line, and to ensure consistency between what
Pfizer says it is going to do and what it actually does. Many Pharmacia
participants shared lessons learned from their previous mergers and acquisitions
experiences. Shedlarz made it clear that Pfizer would take all of these lessons
learned into account during this current process and that Pfizer would place a
great premium on candor in all of its communications.

Bonito also noted the many similarities between the two companies' cultures. For
example, Pfizer's eight core values (Performance, Customer Focus, Integrity,
Teamwork, Respect for People, Community, Leadership, and Innovation) are similar
in spirit to Pharmacia's "4 C's" (Commitment, Competence, Consistency, and
Compassion). Likewise, Pfizer's leader behaviors -- such as "encouraging open
discussion and debate" and "developing people" -- match up quite well with many
of Pharmacia's best-managed behaviors, including "shared accountability and
transparency," "ongoing listening and learning," and "coaching and developing
other colleagues."

In addition to a strong cultural fit, the two companies also share nearly
identical corporate governance structures, which should prove quite helpful as
the transition planning process moves forward. Both companies, for example, have
top-level leadership teams consisting of a handful of senior executives -- the
Pfizer Leadership Team and the Pharmacia Management Committee -- and both have
management councils one level below these teams that include about 20 additional
leaders -- the Pfizer Management Council and the Pharmacia Operations Committee.




Here are some other topics that were discussed at the meeting:

DAY ONE

Shedlarz told the group that the acquisition was likely to close sometime
between November 15 and the end of 2002. He listed several expectations for Day
One:

     o    That one face will be presented to our customers, patients, business
          partners, and colleagues, with no disruptions.

     o    That all colleagues in both companies will know their role and to whom
          they report, even if that reporting relationship may ultimately
          change.

     o    That integration plans are in place to guide activities going forward.

COST SYNERGIES

Pfizer has committed to investors to delivering $2.5 billion in
acquisition-related cost savings through 2005. Meeting this target is extremely
important at a time when investors are severely punishing the stocks of
companies that miss their financial commitments. Shedlarz said that Pfizer
envisions exceeding the $2.5 billion synergy target, noting that any savings
above and beyond that number would be re-invested into areas of the business
that promise to yield the highest payoff. "We see many opportunities for growth
resulting from this combination," he said. "Lowering our cost structure will
give us the additional investment capital needed to aggressively pursue these
opportunities."

CONSULTANTS

Based on its Warner-Lambert experience, Pfizer is trying to minimize the amount
of work done by consultants on the Pharmacia deal, as well as the number of
different consulting firms involved. The Boston Consulting Group has already
been retained by PPG, PGRD [Pfizer Global Research & Development], and Pfizer
Global Manufacturing, as well as by the Program Office, which should help to
ensure consistency and enhance speed.

COMMUNICATIONS

One theme that emerged throughout the meeting was the need for consistent,
global, and timely communications, both internally and externally. Colleagues
will continue to receive a steady stream of information about the transaction
through existing communication vehicles such as the Pfizer World Cafe and
Pharmacia Today, as well as from managers, who will be armed with communications
tool kits.

A town hall meeting is scheduled for September 6 at Pharmacia headquarters in
Peapack, New Jersey. The meeting is expected to feature Pfizer CEO Hank
McKinnell, Shedlarz, PPG President Karen Katen, and Peter Corr, who heads PGRD.
The meeting will be made available live to as many Pharmacia colleagues as
possible using audio and videoconferencing capabilities. A similar meeting is
being planned for Pfizer colleagues, though no date has been finalized yet.




Monitoring "organizational health" -- colleagues' attitudes, opinions, and
concerns resulting from the transition planning process -- is also a top
priority. It was agreed that focus groups, spot polls, and more comprehensive
surveys would be conducted on a regular and ongoing basis at both companies and
in the combined company after Day One.

TALENT PLANNING

Don Nelson, vice president, Human Resources, PPG, and a Program Office member,
described a two-track talent planning process. The first track involves
identifying those Pharmacia colleagues who are absolutely essential to Pfizer's
ability to operate its business as of Day One -- for example, colleagues who
work in a business or therapeutic area that Pfizer does not currently
participate in.

The second track involves identifying key talent from Pharmacia that Pfizer is
interested in retaining regardless of specific business needs. These colleagues
will be identified through discussions between business/division heads from both
companies and by using data generated by Pharmacia's Talent Planning &
Performance Management Process.

Nelson said that Pfizer was committed to finding jobs for as many Pharmacia
colleagues as possible. In fact, Pfizer has instituted a hiring freeze, except
for those positions deemed absolutely critical to meeting the company's 2002
business objectives. This will give Pharmacia colleagues a chance to apply for
positions within Pfizer, though Nelson emphasized that this posting process
would likely not begin until very close to Day One.

NEXT STEPS

The transition team leaders plan to meet again early in the week of September 9
to finalize a number of deliverables they are responsible for providing to the
Pfizer Management Council, which is meeting on September 12-13.
