              Pfizer Remains On Track to Submit an Industry-Record
                  20 Major U.S. Regulatory Filings in 2001-2006

        NEW YORK, April 19 /PRNewswire-FirstCall/ -- Pfizer today reported
financial results for the first quarter of 2005.

        "Pfizer continues to deliver steady performance," said Hank McKinnell,
chairman and chief executive officer.

        "Pfizer's revenue growth of 5 percent in the first quarter was the
product of two underlying forces. One Pfizer markets the broadest array of
in-line and new products in the industry. Excluding the U.S. revenues of
Neurontin, Diflucan, and Accupril -- products that faced generic competition
beginning in 2004 -- and total revenues of Celebrex and Bextra, Pfizer revenues
for the first quarter of 2005 achieved strong double-digit growth. The other
Pfizer is a business going through the natural process of reinventing itself. We
are addressing the loss of exclusivity of a number of products, a situation that
we have long planned for, by advancing a number of internally developed,
in-licensed, and co-promoted product candidates.

        "As the leader of the worldwide pharmaceutical industry, Pfizer has
important competitive advantages that will serve us well and distinguish us from
others in our industry. The unparalleled breadth and depth of our product
portfolio and pipeline clearly demonstrate the unique benefits of Pfizer's scale
and our skill at leveraging the opportunities it provides us. Scale also
enhances our status as 'partner of choice' with other companies who have
promising product candidates and technologies, as well as giving us influence as
a global purchaser of goods and services.

        "Our strategic and operating flexibility allows us to marshal and focus
resources when and where they are needed, to change with a changing environment,
and to recognize and seize emerging opportunities. And our will to succeed in
the important work of improving human health remains as strong as ever," Dr.
McKinnell continued.

        Pfizer revenues for the first quarter of 2005 grew 5 percent to $13.091
billion, compared to the first quarter of 2004, reflecting strong performances
by Lipitor, Zithromax, and other product lines. Revenue growth was also due to
three additional days in our fiscal calendar in the quarter as well as the
weakening of the U.S. dollar relative to a number of foreign currencies, offset
in part by sales declines for Celebrex and Bextra and recent generic competition
in the U.S. against Neurontin, Diflucan, and Accupril.



        The Company's Human Health business generated revenues of $11.440
billion, up 4 percent, in the first quarter compared to the same period in 2004.
Quarterly revenues of Pfizer's Consumer Healthcare business were $945 million,
up 17 percent. Pfizer's Animal Health revenues increased 16 percent in the
quarter to $496 million.

        Reported first-quarter net income of $301 million and reported diluted
earnings per share of $.04 included $622 million ($.08 per share) of significant
impacts of purchase accounting for acquisitions (primarily non-cash charges
attributable to the acquisition of Pharmacia); merger-related costs of $151
million ($.02 per share); certain significant items of $2.955 billion ($.40 per
share), which included $2.189 billion of tax expense related to the planned
repatriation of $28.3 billion in overseas cash later in 2005 and $766 million of
charges attributable to the suspension of sales of Bextra; and income from
discontinued operations of $29 million, all on an after-tax basis. Excluding
these items, adjusted income* in the first quarter of 2005 grew 1 percent
relative to the prior year to $4.000 billion, and adjusted diluted EPS* in the
quarter increased 4 percent to $.54, compared to the same period in 2004.

           Human Health Continues Industry-Leading Revenue Performance

        "While 2005 will be a transitional year for Pfizer, the underlying
strengths that will sustain us through this period and extend our growth into
the future were clearly evident in the solid first-quarter performance of the
Human Health business," said Karen Katen, vice chairman and president, Pfizer
Human Health. "These strengths are founded in the continued growth of many of
our major in-line medicines, along with the growing contributions of our newer
introductions -- growth that is driven by clinical data, continued investment in
new science and clinical trials, and operational execution."

        First-quarter Human Health revenue growth of 4 percent, compared to the
same period in 2004, was led by Lipitor (+23 percent), Aromasin (+134 percent),
Camptosar (+132 percent), Detrol/Detrol LA (+22 percent), Xalatan/Xalacom (+19
percent), Zithromax (+71 percent), Zoloft (+4 percent), Zyrtec (+14 percent),
and Zyvox (+47 percent), as well as newer introductions including Geodon (+56
percent), Relpax (+77 percent), Vfend (+38 percent), and Caduet (+10 percent).
This solid performance across the in-line portfolio more than offset sales
declines, particularly in the U.S., for Celebrex and Bextra, as well as declines
for Neurontin, Diflucan, and Accupril due to generic competition.

        Ms. Katen continued, "Beyond the performance of our current portfolio,
we continue to make significant progress in our longstanding efforts to address
important health needs. Some notable achievements during the first quarter
include the successful introduction in the U.S. of Macugen, a major new medicine
to treat a leading cause of blindness, with the product's discoverer Eyetech
Pharmaceuticals, Inc.; the approval of Vfend in Japan; the acceptance by the FDA
of the filing for Exubera, potentially an important new treatment option for
diabetes under co-development with sanofi-aventis and Nektar Therapeutics;
significant progress in building a flow of new products to replenish and grow
our portfolio, with a pipeline that now spans 149 new molecular entities and 78
product enhancement projects; the evolution of our Human Health organization to
better respond to market needs and become more efficient and productive, which
will also help achieve Pfizer's targeted $4 billion in annualized cost savings
by 2008; and piloting new business approaches that represent solutions to some
of the most urgent problems affecting current healthcare systems in the U.S. and
around the world."

        Response to COX-2 Developments. Following the FDA decision to require
boxed warnings of potential cardiovascular and gastrointestinal risk for all
COX-2-specific pain relievers and all non-steroidal anti-inflammatory drugs
(NSAIDs), including older non-specific drugs such as ibuprofen and naproxen,
Pfizer will work with the FDA to add expanded risk information in the Celebrex
label. Pfizer has accumulated extensive Celebrex clinical data over the past 10
years involving more than 40,000 patients, and we remain committed to conducting
additional long-term clinical studies evaluating the benefits and risks of
Celebrex. Pfizer will also work closely with the FDA to develop a guide to
assist patients and their healthcare professionals in making the best decisions
for treating their arthritis pain.

        Regarding Bextra, Pfizer has suspended its sales in the U.S. in
accordance with the FDA's request. The FDA view is that Bextra's cardiovascular
risk could not be differentiated from other NSAIDs. However, the agency has
concluded that the additional, increased risk of rare but serious skin reactions
associated with Bextra, already described in its label, warrants its withdrawal
from the market. Pfizer respectfully disagrees with the FDA position regarding
the overall risk/benefit profile of Bextra. However, in deference to the
regulatory agency's views, the company has suspended sales of the medicine
pending further discussions with the FDA. For now, patients should stop taking
Bextra and contact their physicians about appropriate treatment options. In
addition, at the request of European and other regulators, Pfizer has also
suspended sales of Bextra in the European Union, Canada, Hong Kong, Singapore,
Malaysia, South Africa, the Philippines, and Mexico. We will explore options
with the regulatory agencies under which the company might be permitted to
resume making Bextra available to physicians and patients. The company is in
contact with other regulatory agencies around the world and will take
appropriate measures based on those discussions.



        Strong Core Business. "While a reduced outlook for the COX-2-specific
medicines and the loss of exclusivity for a number of important products will
make 2005 a transition year for Pfizer, the strong performance across our broad
portfolio of patent-protected medicines during the first quarter indicates that
our core Human Health business remains fundamentally sound. Our portfolio of
medicines is strong, with five of the world's 25 best-selling medicines, and
with 11 medicines that lead their therapeutic areas," Ms. Katen continued. "We
anticipate continued growth for many of our major in-line and recently launched
medicines based on four major drivers: favorable demographic trends as people
live longer; the outstanding need to improve quality of life as people live
longer; epidemiological trends showing enormous unmet medical needs in major
disease areas; and a continual stream of new clinical data demonstrating the
efficacy and therapeutic value of our medicines."

        The ongoing strength of our major in-line medicines, many of which are
fully patent-protected through 2005 and beyond, is most apparent in the
performance of Lipitor. After eight years on the market, it continues
double-digit growth off the largest base of any pharmaceutical medicine ever.
Lipitor had first-quarter revenue of $3.075 billion, ahead 23 percent compared
to the same period in 2004, and showed strong growth in market share and
prescription volume worldwide. Its ongoing success is based on ever-expanding
clinical evidence reinforcing unmatched efficacy and safety. This includes the
most recent results from the Treating to New Targets (TNT) study. TNT found that
intensive therapy with Lipitor 80 mg can reduce cholesterol and cardiovascular
events to among the lowest levels ever achieved in the history of statin trials,
with a safety profile comparable to that of lower-dose Lipitor therapy. These
results take the treatment of cholesterol to new frontiers, while also
reinforcing data from the ASCOT, CARDS, and PROVE-IT studies -- which have all
demonstrated early and significant improvement in cardiovascular outcomes.

        Norvasc first-quarter revenue reached $1.175 billion and is ahead 3
percent compared to the same period in 2004 -- a reduced rate of growth that is
attributable in part to loss of exclusivity in several E.U. countries. Its
performance in the U.S. continues to be strong, with 11 percent growth in the
first quarter, and its new-prescription growth in the U.S. continues to exceed
that of the cardiovascular market. The longstanding leadership of Norvasc in the
antihypertensive market, based on its excellent safety and efficacy, has been
reinforced by recent clinical trials, such as ASCOT, that demonstrate and extend
evidence regarding the outstanding effectiveness of Norvasc.

        Zithromax performance was strong in the first quarter of 2005, based on
its clear benefits as well as an active flu season. It achieved $797 million in
first-quarter revenue, ahead 71 percent compared to the same period in 2004.
Pfizer has filed with the FDA a single-dose Zmax formulation, which would
represent a valuable extension of this important medicine. It offers a one-time
antibiotic course of therapy that will improve compliance by allowing directly
observed therapy in the presence of a healthcare provider.

        With $438 million in first-quarter revenue, ahead 5 percent compared to
the same period in 2004, Viagra is maintaining its market leadership in the face
of competition due to its unique functional and emotional benefits. Additional
growth opportunities for this medicine are expected to result from new clinical
data and sales and marketing efforts that encourage more men to see their
healthcare provider. In December, Pfizer submitted a regulatory filing for
Revatio, which has the same active ingredient (sildenafil) as Viagra, for
treatment for pulmonary arterial hypertension in the U.S., E.U., and other
markets. The FDA accepted the Revatio application for priority review.

        The strong performance of Camptosar during the first quarter, with
revenue of $212 million, ahead 132 percent compared to the same period in 2004,
is due to clear clinical evidence that using Camptosar as standard first-line
treatment in advanced colorectal cancer results in improved survival for
patients, as well as Pfizer's acquisition of rights to this gold-standard
medicine in Europe and Asia (except Japan) in 2004. In the U.S., which
represents approximately half of total Camptosar worldwide sales, revenue was
ahead 30 percent in the first quarter. Camptosar continues to show strong growth
as second- and third-line advanced colorectal cancer therapy, and we anticipate
that new clinical data establishing its efficacy in the first-line setting will
accelerate its growth there as well.

        Among other major in-line medicines, Xalatan/Xalacom achieved
first-quarter revenue of $333 million, ahead 19 percent compared to the same
period in 2004, as well as strong market performance in both new and total
prescriptions. Xalatan is the most-prescribed branded glaucoma medicine in the
world. Clinical data showing its advantages in treating intra-ocular pressure
compared with beta blockers should support the continued growth of this
important medicine.



        Zyrtec revenue reached $342 million, ahead 14 percent compared to the
same period in 2004, and it continues to be the most-prescribed antihistamine
agent in the U.S. in a challenging market. Zyrtec has the broadest range of
formulations and treats patients as young as six months old. Zyrtec received a
warning letter from the FDA on April 13, 2005, addressing three print consumer
advertisements. Pfizer will respond to the FDA in the requested timeframe.

        Worldwide Zoloft sales reached $845 million, ahead 4 percent compared to
the same period in 2004. It has been the number-one prescribed antidepressant in
the U.S. since 2000. A large body of clinical data supports the safety and
effectiveness of Zoloft.

        In addition, recently launched medicines are increasing their revenue
contributions, with additional growth anticipated based on new clinical data and
increasing market acceptance. Lyrica, one of Pfizer's newly launched medicines
in the U.K., Germany, and Mexico, is showing strong performance in its first
year on the market. It is experiencing rapid uptake, with more than an 8 percent
revenue share of the total anti-epileptic market in Germany, and more than a 5
percent share in the U.K, after just five months on the market. This early
success indicates the clear benefits offered by Lyrica, including its efficacy,
with rapid, robust, and sustained pain reduction across the entire dosing range;
its tolerability; and its ease of use. New clinical data from studies presented
at the American Pain Society meeting last month further support the efficacy of
Lyrica in easing neuropathic pain in difficult-to-treat patients, such as those
with spinal-cord injury, and those who have not received adequate relief from
other therapeutic agents. In the U.S., Lyrica is approved for the two most
common forms of neuropathic pain -- diabetic peripheral neuropathy and
post-herpetic neuralgia -- and it is expected to be launched later in 2005.

        Among other recently introduced products with strong first-quarter
performance, Vfend revenue reached $88 million, ahead 38 percent compared to the
same period in 2004. Approval of the new candidemia indication in December 2004
will further strengthen its position in the high-risk market of patients at risk
for both mold and yeast infections, as Vfend is the only intravenous/oral
antifungal with first-line indications for both these infections. Vfend also
received approval in April 2005 in Japan, which is the world's second largest
antifungal market, for a broad first-line antifungal indication.

        Geodon continues to outperform the market, with revenue of $138 million
in the first quarter, ahead 56 percent compared to the same period in 2004. Its
recently launched bipolar mania indication has expanded the pool of patients who
can benefit from this important medicine. The market is accepting its very
distinct benefits, including its efficacy, dosing flexibility, and favorable
metabolic and weight-gain profile compared to older agents. Pfizer, along with
other manufacturers of atypical antipsychotics, recently received a request from
the FDA to add a black-box warning to the Geodon label regarding an increased
mortality risk in patients with dementia-related psychosis. The proposed new
labeling is based on data from 17 placebo-controlled clinical trials of other
atypical antipsychotic agents in patients with dementia-related psychosis.
Geodon is not approved for use in this patient population.

        Revenue for Relpax of $53 million in the first quarter was ahead 77
percent compared to the same period in 2004, and it continues to gain market
share in the $2.3 billion global oral triptan market. It is outperforming the
overall triptan market in the U.S., with the fastest rates of growth in both new
and total prescriptions (65 percent and 87 percent, respectively). Despite being
the sixth medicine to the market, the clear benefits Relpax offers have driven
its growth to be the number-one triptan in switch prescriptions and number-two
in new-to-market prescriptions, behind only Imitrex. The migraine market
continues to represent a large untapped growth opportunity for Relpax, with
diagnosis rates below 50 percent and treatment rates below 20 percent.

        A Promising Pipeline. Beyond the in-line portfolio, Pfizer has also
assembled a range of late-stage pipeline candidates through our internal R&D and
external product sourcing activities that have significant promise for
replenishing and expanding our future portfolio of medicines. Many of these
candidates target disease areas with significant unmet medical needs. For
example, indiplon is for the treatment of patients with insomnia -- a condition
that the National Sleep Association estimates affects at least 70 million
Americans, with potentially another 75 million coping with minor sleeping
disorders. Oporia (lasofoxifene) is for the treatment of osteoporosis, which
affects around 10 million Americans and results in an annual economic cost of
about $14 billion, not to mention the huge toll on health from 300,000 hip
fractures a year caused by untreated osteoporosis. Exubera is for the treatment
of patients with diabetes, the sixth-leading cause of death in the U.S. with
over 50,000 deaths annually.

        Ms. Katen noted, "These statistics are startling. They certainly
highlight the urgency of getting our new medicines to the market as important
new treatment options for patients and their caregivers. Our research and
development organization is well on its way to delivering these and many other
important new medicines from our labs to the market."



        "The first quarter of 2005 was again productive for Pfizer R&D," said
Dr. John LaMattina, President, Pfizer Global Research and Development. "Pfizer's
development pipeline continues to grow and now includes 149 new molecular
entities and 78 product enhancement projects. Our discovery research engine is
reliably generating new development substrate, advancing ten new candidates into
pre-clinical development during just the first quarter. Research and early
development output is augmented by an active licensing and technology alliance
effort that is completing deals at a pace of one every two weeks. The advanced
development pipeline, including key compounds such as Sutent, varenicline,
maraviroc (UK-427,857), asenapine, torcetrapib/ atorvastatin, and Daxas,
continues to progress. We expect to achieve our goal of filing 20 U.S.
regulatory filings in the five-year period ending in 2006, or about one new
filing per quarter.

        "Our productivity initiative to better utilize our wide-ranging R&D
capabilities is proceeding on schedule," Dr. LaMattina continued. "We are
maintaining a clear focus on key objectives -- increasing R&D productivity while
operating at ever higher levels of efficiency."

        Specific R&D highlights during the first quarter include the following:

        *   The FDA accepted the New Drug Application (NDA) filing for Exubera,
            or inhaled insulin. In Europe, review of the Marketing Authorization
            Application for Exubera is actively proceeding.

        *   A revised NDA for Lyrica for the treatment of add-on epilepsy was
            submitted to the FDA. Lyrica was approved by the FDA in 2004 for the
            treatment of diabetic peripheral neuropathy and post-herpetic
            neuralgia and will be launched in the U.S. for these indications,
            pending the completion of a scheduling designation by the U.S.
            Department of Health and Human Services and the U.S. Drug
            Enforcement Administration.

        *   A supplemental NDA was approved for Depo-subQ Provera for treatment
            of endometriosis pain.

        *   The development program for Sutent, a multi-targeted tyrosine kinase
            inhibitor for potential treatment of gastrointestinal stromal
            tumors, renal cell carcinoma, and breast cancer, was accelerated
            when an independent data safety monitoring board halted pivotal
            Phase 3 trials seven months early because a statistically
            significant efficacy endpoint was successfully achieved.

        Important new-product sourcing deals that have been completed in the
first quarter include the acquisition of Idun Pharmaceuticals, a
biopharmaceutical company that we agreed to acquire during February of this
year. Idun is focused on the discovery and development of therapies to control
caspase activity. Their lead compound, IDN-6556, is a first-in-class pan-caspase
inhibitor, currently in clinical trials to treat liver disease and hepatitis C
infection. In addition, Pfizer reached a collaborative research and license
agreement with Rigel Pharmaceuticals for the development of inhaled products for
treating allergic asthma and other respiratory diseases; entered an agreement
with LifeSpan Biosciences to develop an automated pathology system for rapid and
accurate evaluation of tissue specimens in preclinical studies; and gained an
exclusive license from Coley Pharmaceuticals to develop, manufacture, and
commercialize Coley's ProMune (CPG 7909), a toll-like receptor (TLR 9) agonist
delivered by subcutaneous injection for the potential treatment, control, and
prevention of cancers in humans.

        Streamlining Business to Improve Performance and Efficiency. Ms. Katen
continued, "Beyond extensive efforts in the Human Health organization to support
our business performance through growing our current portfolio and supporting
the medicines that will create our future portfolio, we are also focused on
targeting our resources toward activities that are most vital to ensuring the
continued success of our pharmaceutical operations. Various efforts are underway
across our Human Health organization to accomplish this, including the
realignment of our U.S. field force, already long recognized as the industry's
best in quality and productivity, in response to a changing promotional
environment."

        Other organizational changes include the continued implementation of
Pfizer Global Manufacturing's (PGM's) Plant Network Strategy, initiated after
the Pharmacia acquisition in 2003 to assure that our global manufacturing plant
network is in close alignment with Pfizer's current and future product supply
requirements. Recent announcements include the divestment of facilities in
Augusta, Georgia; Holland, Michigan; Angers and Val-de-Reuil, France; and
Morpeth, U.K.; and the restructuring of facilities in Arecibo, Caguas, and Cruce
Davila, Puerto Rico, and Sandwich, U.K.

        Pfizer is also working to better realize the strategic advantages and
meet the efficiency goals of our unmatched global research and development
organization, which, with an annual investment in 2005 of approximately $8
billion -- or more than $20 million a day -- make it one of the world's largest
research institutions. Some actions include concentrating certain operational
functions such as bio-imaging in selected "centers of emphasis"; considering the
potential benefits of sourcing certain tasks in lower-cost environments;
streamlining our wide-ranging sample and clinical supply network; implementing
more efficient clinical-study designs; and continuing to fully leverage our
scale advantage in procurement.



        New Approaches to Healthcare Delivery. "Beyond efforts to improve our
internal operational efficiencies, we are implementing a series of initiatives
that respond to the most urgent constraints on our continued vitality as a
pharmaceutical innovation business," Ms. Katen said. "These pressures are
grounded in concerns about the cost of, and access to, medicines; a deep-seated
mistrust of some industry practices; and strained healthcare systems that are
increasingly unable to finance quality care delivery.

        "We recognize the urgent need to expand how we provide value to
stakeholders beyond medicines. We are moving toward that goal by extending our
tradition of innovation to the entire process of getting new medicines to the
people who need them, effectively and efficiently. By doing so, we believe that
we will ultimately both enhance our leadership in health and protect our future
in pharmaceutical innovation."

        To that end, our efforts include:

        Expanding Easy Access to Affordable Medicines. Pfizer already has among
the industry's most comprehensive, generous, and easy-to-use access programs for
uninsured and low-income patients. We are now focused on expanding, and
enrolling more people in, these programs through community-based outreach
efforts and by participating in Partnership for Prescription Assistance, a new
industry-wide umbrella program created by the Pharmaceutical Research and
Manufacturers of America.

        Piloting New Models of Care. We are developing and implementing a series
of initiatives to address inefficiencies in healthcare, both in the U.S. and
around the world. These are all based on the fundamental premise that better
health at lower costs is possible through patient-centered and integrated care
delivery that is focused on prevention, early intervention, and appropriate use
of medicines. These initiatives include our first model, the Florida: A Healthy
State program; its expansion to several European markets; the redesign of
Pfizer's own employee healthcare program in the U.S. to be focused more on
health and well-being; and our new Green Ribbon Health program in partnership
with Humana to provide care-management services to approximately 20,000 Medicare
patients in Florida with congestive heart failure, diabetes, or both.

        "While it will undoubtedly take time for these efforts to deliver
results, we are confident in their ultimate success because they all have one
primary purpose: serving patients. Meeting the needs of patients and
establishing the value of health will also serve the best interests of the
public, of our communities, of our business, and ultimately of all our
stakeholders," Ms. Katen concluded.

             Pfizer Provides Revised Financial Guidance for 2005-07

        David Shedlarz, vice chairman, noted, "In the first quarter, Pfizer
performed well, and the company's long-term prospects remain strong.

        "We expect 2005 to be a transition year for Pfizer due to a number of
factors. Results in 2005 are being, and will continue to be, impacted by loss of
U.S. exclusivity of four major products -- Diflucan, Neurontin, and Accupril
during 2004 and Zithromax in 2005. Revenues also have been, and will continue to
be, impacted by publicity and regulatory actions regarding COX-2-selective
inhibitors. Full-year revenues are expected to be substantially unchanged from
2004, as growth from other product lines generally offsets these factors. The
suspension of sales of Bextra in the U.S., E.U., and other markets in early
April is expected to reduce our previously announced targeted full-year 2005
adjusted and reported diluted EPS* by approximately $.05 per share. Bextra asset
write-offs are expected to reduce our previously announced targeted full-year
2005 reported diluted EPS by an additional $.10 per share. However, 2005 results
are no longer expected to be impacted by the adoption of new accounting
regulations relating to the expensing of stock options, pursuant to a deferral
in the implementation date of the new regulations, as announced by the SEC last
week. These regulations had been expected to result in an after-tax expense
reducing 2005 adjusted and reported diluted EPS* by $.03 per share. Pfizer
expects to implement SFAS 123R regarding expensing of stock options as of
January 1, 2006. From an efficiency perspective, in 2005 we continue to
anticipate Pharmacia merger-related synergies of $4.2 billion this year, an
increase of $600 million over 2004 Pharmacia merger-related synergies. Pfizer
will also achieve modest cost savings during 2005 from its newly announced
productivity initiative. Given these and other factors, we expect 2005 adjusted
income* of approximately $14.7 billion, adjusted diluted EPS* of approximately
$1.98 per share, reported income of approximately $7.7 billion, and reported
diluted EPS of approximately $1.04 per share, subject to the Disclosure Notice
in this report.



        "The differences between targeted 2005 adjusted income* and adjusted
diluted EPS* and 2005 reported income and reported diluted EPS are attributable
to anticipated non-cash charges of $2.6 billion ($.36 per share) relating to
purchase accounting for the acquisition of Pharmacia and an in-process research
and development charge relating to our recently completed acquisition of Idun
Pharmaceuticals, Inc.; merger-related and restructuring costs of $1.4 billion
($.18 per share), which include both Pharmacia-related charges and charges
related to the recently announced planned productivity initiative; and charges
relating to the suspension of sales of Bextra of $.8 billion ($.10 per share),
all on an after-tax basis. In addition, reported net income for 2005 will
include a tax charge of $2.2 billion ($.30 per share) relating to the cash
repatriation of foreign earnings in 2005, with a possible subsequent reduction
of this charge by about $850 million, due to anticipated technical corrections
legislation. All of these estimates are subject to the variables cited in the
Disclosure Notice found in this report.

        "We will sustain both the capability and will to make those investments
necessary to support long-term growth. Pfizer's financial strength remains
unprecedented and will be enhanced by the cash repatriation of $28.3 billion in
foreign earnings during this year. With the current quarterly dividend of $.19
per share, which is 12 percent higher than last year, we are continuing the
company's commitment to strong growth in dividends, both today and in the
future. We will accelerate and complete our current share-purchase program in
the second quarter by purchasing approximately $2.4 billion of the company's
stock in this quarter, and early in the second half we will consider additional
opportunities to purchase the company's stock.

        "A number of factors are expected to drive a return to double-digit
adjusted earnings* growth in 2006. We are undertaking a new, broad-based,
multi-year productivity initiative to increase efficiency and effectiveness of
all operations company-wide. Annual savings are projected to total $4 billion by
2008. Improved revenue performance is also anticipated, as many of our in-line
products continue to grow, we experience renewed growth of Celebrex, and the
contribution of new products increases.

        "Revenue growth, enhanced by continuing productivity initiatives, is
expected to drive a strong 2007, when we anticipate accelerating double-digit
adjusted earnings* growth," Mr. Shedlarz concluded.

        "Several factors affected first-quarter results, including several
unique to the quarter," said Alan Levin, chief financial officer. "Revenue
growth benefited from strong performances of many major in-line medicines, as
well as three additional days in our fiscal calendar compared to the first
quarter of 2004. Cost of sales as a percentage of revenues in the first quarter
of 2005 was adversely impacted by changes in production volume, as well as
geographic, segment, and product mix, reflecting the loss of exclusivity of
certain major products in the U.S. and lower year-over-year sales of COX-2
products, compared to the first quarter of 2004, and charges for write-offs of
inventory related to the suspension of Bextra sales. Cost of sales as a
percentage of revenues will remain under pressure in 2005. R&D spending
increased 7 percent in the quarter, reflecting the advancement of our pipeline
products. Full-year R&D spending is expected to be approximately $8 billion.
Finally, the effective tax rate on adjusted income* increased to 23 percent,
reflecting changes in geographic and product mix.

        "In connection with the decision to suspend sales of Bextra, we recorded
certain charges totaling $1.213 billion ($766 million, net of tax) in the first
quarter of 2005. These pre-tax charges included $1.145 billion relating to the
impairment of Bextra's intangible assets for developed technology rights, $10
million related to the write-off of machinery and equipment, $56 million in
write-offs of inventory, and $2 million relating to the costs of administering
the suspension of sales. In addition, we recorded in the first quarter of 2005 a
net charge of $71 million, substantially against revenues, for estimated
customer returns of Bextra."

                          Pfizer Expands Patient-Access
                      And Corporate-Citizenship Initiatives

        During the first quarter of 2005, Pfizer continued its mission to expand
patient access to medicines and to demonstrate good corporate citizenship.

        In the aftermath of the tsunami disaster, Pfizer has donated
approximately $60 million (at wholesale price) of antibiotics, antifungal
medicines, and other health products to local and international relief
organizations operating in the Asian region. We are partnering with the United
Nations by sending Pfizer experts in supply-chain management to the affected
areas to support the U.N.-led relief efforts. We have also sent more colleagues
to lend support in areas of critical need, such as water purification.

        In February, Pfizer also convened a first-ever conference for healthcare
professionals from tsunami-affected countries in managing post-traumatic stress
disorder. The company also is working closely with medical associations and the
Ministry of Public Health in Thailand to build local mental-health treatment
capacity through programs to train local health professionals, including nurses,
social workers, and psychologists, and other community leaders. In Indonesia,
Pfizer has pledged more than $600,000 to establish a Public Health Laboratory to
monitor potential infectious-disease outbreaks in the disaster-affected region.
The laboratory will become a permanent component of the provincial health
infrastructure in Banda Aceh as services are re-established following the
emergency relief period.



        In addition to these activities, Pfizer employees have committed
personal funds totaling more than $2 million to non-profit organizations
assisting in the relief effort, with Pfizer and the Pfizer Foundation providing
matching support.

            Pfizer Has the Capabilities to Meet the Challenges Ahead

        "Pfizer today faces a paradox," Dr. McKinnell concluded. "On the one
hand, the opportunities for bringing innovative, life-saving medicines to the
world's patients have never been greater. On the other hand, the challenges for
innovative companies like Pfizer have also never been greater. But Pfizer has
faced important challenges before and has always addressed them with energy and
resolve and emerged a stronger company. Pfizer has a dynamic organization of
dedicated colleagues to navigate the challenges that lie ahead, and I appreciate
all their efforts. I am confident that Pfizer's people, equipped with our
innovative products and unsurpassed capabilities, will rise to the occasion once
again and propel our company to long-term success."

QUESTIONS:

PRODUCT PERFORMANCE / NEW PRODUCT DEVELOPMENT

CARDIOVASCULAR / METABOLIC / ENDOCRINE

Q1)     How is Lipitor performing?

A1)     Worldwide sales of Lipitor totaled $3.075 billion in the first quarter
        of 2005, reflecting growth of 23% compared to the same period in 2004.
        Lipitor is the best-selling pharmaceutical product of any kind in the
        world and the industry's first $10 billion product. Lipitor's full-year
        2004 growth outpaced the lipid- lowering market in both sales and unit
        volume worldwide. Lipitor's strong worldwide performance is supported by
        the continued strong performance in the U.S. market. Year-to-date U.S.
        new prescriptions for Lipitor grew 11%, setting the pace in a strong
        growth market.

        This impressive performance can be attributed to the safety and efficacy
        profiles of Lipitor, including demonstrated strong cholesterol
        reduction, a proven cardiovascular (CV) outcomes benefit, and safety for
        patients across the full dosing range in more than 400 ongoing and
        completed clinical trials involving more than 80,000 patients and in 100
        million patient years of experience. Also supporting this impressive
        performance are new groundbreaking clinical data, more aggressive
        treatment guidelines, and increased promotion within the category.
        Lipitor has a growing body of evidence demonstrating benefit to patients
        by impacting disease progression and by reducing heart attacks and
        strokes (the ASCOT, CARDS, REVERSAL, PROVE-IT, and ALLIANCE clinical
        trials).

        Emerging results from a new clinical study -- Treating to New Targets
        (TNT) -- were reported at the American College of Cardiology on March 8.
        These results take the treatment of high cholesterol to new frontiers,
        while also reinforcing data from the ASCOT, CARDS, and PROVE-IT studies,
        which all demonstrated early and significant improvement in
        cardiovascular outcomes. TNT is an innovative and important landmark
        outcomes study that investigated the CV benefit of lowering LDL
        cholesterol well below current guidelines in patients with coronary
        heart disease (CHD). It is the largest and longest clinical trial of its
        kind. TNT found that intensive lipid- lowering therapy with Lipitor 80
        mg in patients with stable CHD provides significant clinical benefit
        beyond that afforded by treatment with Lipitor 10 mg. This five-year
        trial builds on the well-established safety profile of Lipitor 80 mg,
        demonstrating musculoskeletal safety comparable to the 10 mg dose. The
        TNT results have been published online in the New England Journal of
        Medicine and will appear in its April print issue.



        There continues to be an opportunity for further growth of the
        cholesterol-lowering market. Of the tens of millions of people around
        the world who need medical therapy for high cholesterol, only about one
        third are actually receiving treatment. Worldwide, millions of people
        with high cholesterol are not diagnosed, are not treated, or are treated
        with a dose inadequate to achieve their cholesterol goals. Evolving
        treatment guidelines continue to encourage the broad use of statin
        therapy.

Q2)     How is Caduet performing?

A2)     Worldwide sales of Caduet totaled $31 million in the first quarter of
        2005, reflecting growth of 10% compared to the same period in 2004. The
        market performance of Caduet in the U.S. continues to improve. U.S.
        sales of Caduet doubled, and weekly new-prescription volume increased
        27%, in the first quarter of 2005 versus the fourth quarter of 2004.
        Momentum continues to grow behind Caduet due to increased product
        awareness and acceptance by physicians.

        The FDA approved Caduet in January 2004, and Pfizer launched the product
        in the U.S. in May. The first E.U. filing was submitted in France, the
        reference member state for Caduet, in the fourth quarter of 2003. We
        will be pursuing E.U. approvals through the mutual recognition process.
        Caduet has been launched in Mexico and has been approved in ten
        additional countries throughout Latin America and Asia.

        Caduet provides an opportunity to address simultaneously two of the most
        common risk factors of cardiovascular disease with the world's most
        prescribed branded blood-pressure medication -- Norvasc -- and
        lipid-lowering medication -- Lipitor -- in one pill. In September 2004,
        the FDA approved changes to the prescribing information for Lipitor and
        Caduet to include prevention of cardiovascular disease. The results of
        the Anglo-Scandinavian Cardiac Outcomes Trial-Lipid Lowering Arm
        (ASCOT-LLA) bring a critical new insight into the management of
        hypertensive patients -- that hypertensive patients benefit from Lipitor
        in addition to blood-pressure -- lowering therapy.

        In December 2004, Pfizer announced that the independent ASCOT steering
        committee had decided to stop the study in its entirety due to favorable
        benefits being seen in patients receiving the Norvasc- based treatment
        regimen. Preliminary results were presented at the American College of
        Cardiology (ACC) meeting on March 8, 2005. The fully analyzed ASCOT
        results are anticipated later in 2005. The clinical benefits of Caduet
        are reinforced by these positive results from Norvasc as well as those
        for Lipitor, including the results of the Treating to New Targets study
        that were also presented at the ACC meeting. These robust scientific
        data continue to reinforce Caduet's efficacy and safety in preventing
        cardiovascular events in hypertensive patients, with or without coronary
        heart disease.

        By current estimates, each year 9 million deaths around the world,
        equaling more than 75 million lost years of healthy life, may be
        attributed to suboptimal blood-pressure or cholesterol levels. Treatment
        guidelines advocate early and aggressive management of multiple risk
        factors for patients at increased cardiovascular risk.



Q3)     How is Norvasc performing?

A3)     Worldwide sales of Norvasc in the first quarter of 2005 totaled $1.175
        billion, reflecting growth of 3% compared to the same period in 2004.
        The reduced rate of growth is attributable in part to patent expirations
        throughout the E.U., except for Italy, France, Sweden, and Switzerland.
        Norvasc maintains exclusivity in many markets globally, including the
        U.S., Japan, Canada, and Australia. Norvasc's performance in the U.S.
        continues to be strong, with 11% growth in sales, and its
        new-prescription growth in the U.S. continues to exceed that of the
        cardiovascular market.

        Since its introduction in 1990, Norvasc has become the world's most-
        prescribed branded antihypertensive therapy. Overall, Norvasc has been
        studied in more than 400,000 patients and has been used in more than 30
        billion patient days of therapy worldwide. Its success has been driven
        by its outstanding efficacy, once-daily dosing, consistent 24-hour
        control of hypertension and angina, and excellent safety and
        tolerability. In addition, the results from the ALLHAT, VALUE, and
        CAMELOT/NORMALISE trials demonstrate the beneficial effects of Norvasc
        on multiple cardiovascular outcomes. An FDA advisory committee is
        anticipated later this year to review the ALLHAT filing for Norvasc.

        Hypertension affects about 50 million Americans and one billion people
        worldwide. Currently 69% of American adults diagnosed with hypertension
        are not at their blood-pressure goal. Recent guidelines call for early,
        aggressive blood-pressure management and make clear that the majority of
        patients may require two or more medications to reach their
        blood-pressure targets.

        In December 2004, Pfizer announced that early indications from the
        landmark Anglo-Scandinavian Cardiac Outcomes Trial (ASCOT) showed that
        patients receiving a treatment regimen based on Norvasc experienced
        favorable cardiovascular benefits. As a result of these findings, the
        independent ASCOT steering committee decided to stop the trial early so
        that investigators and patients in the trial could discuss their optimum
        hypertension treatment moving forward. Preliminary results were
        presented at the American College of Cardiology meeting on March 8,
        2005. These data showed that patients receiving the Norvasc-based
        regimen demonstrated a 25% reduction in cardiovascular death and a 15%
        reduction in total mortality. These patients experienced a 10% reduction
        in the primary endpoint (fatal coronary heart disease and non-fatal
        heart attack), which did not reach statistical significance. This is
        thought to be due to the widespread use of statins throughout the trial
        as well as its premature termination, which reduced the number of
        primary endpoints. Among the Norvasc-based regimen's other benefits were
        significant reductions in stroke, coronary events, and new-onset
        diabetes. The final results of this study are expected to be presented
        and published in a peer-review journal later in 2005.

Q4)     What is the status of Exubera?

A4)     Exubera(R) is a dry powder form of insulin that is inhaled into the
        lungs prior to eating using a specially designed inhalation device. The
        product candidate is under development through a collaboration between
        Pfizer and sanofi-aventis. Pfizer is also collaborating with Nektar
        Therapeutics, developer of the inhalation device and formulation process
        for Exubera. The product has been studied in more than 3,500 patients,
        some for more than seven years. As an effective alternative to insulin
        injections, Exubera has also been shown in clinical trials to be
        preferred by patients. This patient preference may encourage patient
        acceptance of, and compliance with, insulin therapy, thereby improving
        the health of diabetics and reducing the healthcare costs associated
        with the disease.

        On March 2, 2005, Pfizer and sanofi-aventis announced that the FDA had
        accepted for filing a New Drug Application for Exubera. The companies
        seek approval to market Exubera for adult patients with type 1 and type
        2 diabetes. A filing for Exubera is currently under review by the
        European Medicines Evaluation Agency.

        It is estimated that nearly 180 million people worldwide suffer from
        diabetes, and the number is expected to rise to 300 million people in
        the next 20 years. More than half of people with diabetes remain
        uncontrolled or poorly controlled and are at risk for common
        complications such as heart disease, stroke, kidney failure, nerve
        damage, and blindness. Annual costs associated with the disease are
        estimated at $186 billion worldwide.



Q5)     What is the status of Revatio?

A5)     Revatio(TM) (sildenafil citrate) was submitted to the FDA, the European
        Medicines Evaluation Agency, and Health Canada in December 2004 as a
        treatment for pulmonary arterial hypertension (PAH). PAH is a rare,
        progressive, and life-shortening vascular disease affecting
        approximately 100,000 people in North America and Europe. The FDA has
        accepted the Revatio application for priority review.

        If approved, Revatio is expected to offer an unprecedented combination
        of efficacy, safety, and cost effectiveness for a disease in need of new
        oral treatment options. In a large, multinational clinical trial
        (SUPER-1) presented at the 2004 American College of Chest Physicians
        annual meeting, Revatio 20mg taken three times daily was found to be
        effective, safe, and well tolerated over 12 weeks. One-year data from
        SUPER-1 showing the effects of Revatio on exercise capacity, survival,
        and disease severity (based on functional class) will be presented at
        the 2005 International Conference of the American Thoracic Society in
        May. Health-related quality-of-life data from SUPER-1 will also be
        presented at the conference. Sildenafil is the same active ingredient in
        Viagra(R), the world's leading erectile-dysfunction medication, used by
        more than 23 million men worldwide based on its excellent efficacy and
        safety.

Q6)     What is the status of the torcetrapib/atorvastatin program?

A6)     A combination product of torcetrapib, a cholesteryl ester transfer
        protein (CETP) inhibitor, and atorvastatin (Lipitor) is now in global
        Phase 3 clinical trials. The objective of this comprehensive
        12,000-patient subject program is to demonstrate improved efficacy and
        comparable safety of this novel product versus atorvastatin alone, other
        statins, and fibrates in a wide range of patients at cardiovascular
        risk. The program includes comparative atherosclerotic imaging trials
        involving coronary intravascular ultrasound and carotid ultrasound
        technology, as well as a full range of blood-lipid efficacy studies. The
        program is designed to provide substantive evidence of the vascular
        benefits of raising HDL cholesterol and further lowering LDL cholesterol
        over the established clinical benefits of atorvastatin's powerful LDL-
        cholesterol lowering. Although a high hurdle has been created,
        demonstration of such benefits would provide support for use of
        torcetrapib/atorvastatin in patients currently being treated with
        atorvastatin and other statins. Additional scientific and mechanistic
        studies are also underway to broaden our understanding of the effects of
        CETP inhibition on lipid metabolism and atherosclerosis. The development
        program is also enrolling 13,000 patients in a definitive mortality and
        morbidity trial. This program represents the major commitment by Pfizer
        to significantly advance our understanding of lipids and atherosclerosis
        to provide an important new tool for patients and prescribers in
        preventing and treating the global burden of cardiovascular disease.

        Data from Phase 2 studies assessing torcetrapib's impact on lipid levels
        in patients with low HDL cholesterol alone and on a background of
        atorvastatin treatment were reported at the recent American College of
        Cardiology meeting. Torcetrapib, both alone and on a background of
        atorvastatin, was found to substantially raise HDL cholesterol. However,
        consistent LDL-cholesterol lowering with torcetrapib was only seen in
        the patients taking background atorvastatin. Torcetrapib, both alone and
        in combination with atorvastatin, was well tolerated in these early
        Phase 2 studies.



        The rationale for initial development of a fixed-combination tablet of
        torcetrapib and atorvastatin, rather than of torcetrapib alone as a
        monotherapy or as add-on therapy to any statin, is to provide optimal
        lipid treatment for the majority of dyslipidemic patients. The basis for
        this decision includes the complementary pharmacologic actions of HMG
        Co-A reductase inhibition -- the mechanism of action of statins -- and
        CETP inhibition on modifying lipid metabolism, with supporting Phase 2
        clinical observations. The torcetrapib/atorvastatin combination also
        provides the mandatory LDL-cholesterol control that patients at risk for
        heart disease need. Current guidelines recommend intensive
        LDL-cholesterol reduction in patients with cardiovascular risk, using a
        dose of a statin that would provide at least a 30% reduction in LDL
        cholesterol. This is the case even for patients with "isolated" low HDL
        cholesterol, since current treatment guidelines recommend LDL-
        cholesterol reduction in these patients. Torcetrapib as a monotherapy
        did not adequately or consistently lower LDL cholesterol in the Phase 2
        studies described above and therefore would not be appropriate as a
        monotherapy. The choice of atorvastatin as the companion statin was
        based on its powerful LDL-cholesterol and triglyceride lowering, which
        has been proven to be safe and clinically effective across its full dose
        range. Atorvastatin is the best statin on the market, with a robust
        clinical-trial database. Therefore, we believe it was critically
        important to combine torcetrapib with the best available agent --
        atorvastatin. The combination of torcetrapib with atorvastatin has the
        potential as a novel therapy to extend the proven benefits of
        LDL-cholesterol lowering by adding substantial HDL-cholesterol elevation
        to further reduce atherosclerosis and cardiovascular events beyond what
        is currently achievable.

Q7)     What is the status of varenicline?

A7)     Varenicline is an innovative agent, in Phase 3 development, that was
        researched and developed specifically for smoking cessation. Data
        presented at the recent American College of Cardiology and Society for
        Research on Nicotine and Tobacco meetings showed that varenicline may
        offer an advance over existing prescription smoking- cessation
        treatments. In two Phase 2 trials evaluating the efficacy, safety, and
        tolerability of different doses of varenicline in healthy smokers, about
        half of smokers treated with varenicline 1mg twice daily stopped
        smoking. In 2000, it was estimated that there were 1.25 billion smokers
        worldwide and that nearly 5 million premature deaths per year globally
        were attributable to smoking. Seven out of ten smokers are contemplating
        quitting or actively want to quit; however, only 3-5% of patients can
        quit on their own. More-effective treatments are needed for smoking
        cessation than are provided by currently available products. In contrast
        to a nicotine derivative or an antidepressant, varenicline was designed
        to selectively target the alpha 4-beta 2 nicotine receptors in the brain
        and therefore to have the unique benefits of reducing craving and the
        related withdrawal symptoms of quitting and of blocking the rewards from
        smoking that perpetuate dependence. Varenicline illustrates Pfizer's
        leadership in providing innovative products to treat cardiovascular risk
        factors and the complications often associated with smoking.

RESPIRATORY

Q8)     How is Spiriva performing?

A8)     Spiriva is an anticholinergic medication and the first inhaled chronic
        obstructive pulmonary disease (COPD) treatment to provide significant
        and sustained improvements in lung function with once- daily dosing.
        Pfizer co-promotes Spiriva with the product's discoverer, Boehringer
        Ingelheim. With 136% year-over-year growth in full-year 2004 worldwide
        audited sales, Spiriva's performance continue to outpace the overall
        COPD market. The product is currently available in more than 50
        countries and is the best- selling COPD product in seven countries,
        including Germany and Australia. Recent launches in the U.S. (June
        2004), Italy (July 2004), and, most recently, Japan (December 2004)
        continue to go well.



        Clinical trials have shown that patients with all stages of COPD, from
        mild to severe, can benefit from taking Spiriva. Trials have also
        demonstrated that Spiriva provided superior and sustained improvements
        in lung function, breathlessness, health-related quality of life, and
        exercise tolerance in COPD patients. Spiriva also provides sustained and
        significant improvements in lung function compared to ipratropium, the
        currently recommended first- line therapy outlined in many treatment
        guidelines. Spiriva has also been shown to significantly reduce COPD
        exacerbations and related health-resource burden versus placebo on top
        of usual care, including inhaled corticosteroids and long-acting beta
        agonists.

        In a study recently published in Chest, Spiriva was shown to be the
        first product to consistently enhance the well-known exercise- training
        benefits of pulmonary rehabilitation in patients with COPD. This study
        builds upon previous studies with Spiriva, which have demonstrated
        significant improvement in exercise tolerance, shortness of breath, and
        quality of life when compared with placebo. In the study, Spiriva was
        associated with prolonged (24-hour) improvements in lung function as
        well as improvements in exercise- endurance time, further augmenting
        benefits of pulmonary rehabilitation. Spiriva may be an important tool
        for physicians to break the vicious downward spiral of dyspnea,
        inactivity, and subsequent deconditioning.

Q9)     How is Zyrtec performing?

A9)     Worldwide sales of Zyrtec totaled $342 million in the first quarter of
        2005, reflecting an increase of 14% compared to the same period in 2004.
        The product continues to be the most-prescribed antihistamine agent in
        the U.S. in a challenging market. Zyrtec continues to lead Allegra by a
        wide margin in prescriptions by key specialists -- allergists and
        pediatricians. The decline experienced in the prescription antihistamine
        market for the past two years has leveled off, as much of the impact of
        cheaper over-the-counter and private-label loratadine (Claritin)
        products has been realized and the majority of managed-care plans have
        completed their formulary tier changes in this category. Zyrtec is
        indicated for both seasonal and perennial allergic rhinitis. It has the
        broadest range of formulations and treats patients as young as six
        months old.

Q10)    What is the status of Daxas (roflumilast)?

A10)    Daxas is a phosphodiesterase-4 inhibitor, a class of compounds that
        provides anti-inflammatory action for respiratory diseases. The compound
        is currently being studied for both asthma and chronic obstructive
        pulmonary disease (COPD), two respiratory diseases associated with
        substantial morbidity and mortality. COPD affects 600 million people
        worldwide and kills more than 2.75 million people each year, according
        to estimates by the World Health Organization. The Global Burden of
        Disease Studies found that COPD was the sixth- most-common cause of
        death worldwide in 1990 and predicted that it would become the
        third-most-common cause of death by 2020. In the U.S., COPD is currently
        the fourth-leading cause of death (behind heart disease, cancer, and
        stroke), with death rates having increased 22% in the last decade.
        Asthma affects more than 300 million people worldwide and kills 180,000
        people each year. Pfizer and our co-promotion partner Altana Pharma
        filed Daxas in the E.U. for both asthma and COPD indications. For other
        markets, the product is in late-stage development.

UROLOGY

Q11)    How is Detrol/Detrol LA performing?

A11)    Worldwide sales of Detrol/Detrol LA totaled $252 million in the first
        quarter of 2005, reflecting growth of 22% compared to the same period in
        2004. The robust performance was due to Detrol LA's strong competitive
        positioning in the U.S. and E.U. and successful launches of the
        once-daily formulation in Asia and Latin America. For the first time,
        in-market sales of Detrol/Detrol LA, as reported by IMS, exceeded $1
        billion on an annualized basis. Recent competitive launches have
        stimulated overall growth of the overactive bladder (OAB) category, with
        minimal impact on Detrol/Detrol LA's leading position in the market.
        Detrol/Detrol LA remains the most-prescribed brand globally, with more
        than 8.5 million patients worldwide since launch and a 51% market share.



        OAB is a highly prevalent and bothersome condition, affecting 50-100
        million people worldwide, with an approximate 16% prevalence in adults
        in the U.S. and E.U. The market opportunity is significant, since OAB
        remains underdiagnosed and undertreated. Detrol/Detrol LA is the leading
        OAB therapy worldwide, delivering proven 24-hour efficacy across OAB
        symptoms of urge incontinence, urgency, and frequency, resulting in
        excellent patient-reported treatment outcomes.

        Further evidence of Detrol/Detrol LA's patient benefits was presented in
        March at the annual Congress of the European Association of Urology in
        Istanbul. Study results confirmed that Detrol LA reduces OAB symptoms in
        as little as five days. A systematic review of 56 clinical trials
        covering all antimuscarinics in widespread clinical use demonstrated
        very low total withdrawals from treatment for Detrol LA. In addition,
        new data were released demonstrating Detrol LA significantly reduced
        nighttime OAB voids with favorable tolerability, as well as long-term
        efficacy and safety.

Q12)    How is Viagra performing?

A12)    Worldwide sales of Viagra totaled $438 million in the first quarter of
        2005, a 5% increase compared to the same period in 2004, reflecting
        Viagra's stabilization after the introduction of competition. Viagra
        maintains a strong leadership position, with a 68% worldwide market
        share of audited sales of phosphodiesterase-5 inhibitors for the twelve
        months ending January 2005.

        More than 130 clinical trials worldwide and more than six years of
        real-world experience have shown that Viagra provides hard, long-
        lasting erections that instill confidence in men, while maximizing both
        patient and partner satisfaction. Studies have shown that Viagra
        improves erections in up to 82% of men with erectile dysfunction (ED).
        Men taking Viagra also report a 77% improvement in their confidence to
        get and maintain an erection, compared to only 18% taking placebo. After
        four years of treatment, 96% of Viagra users and 92% of their partners
        report being highly satisfied with the product, with 95% of partners
        expressing a desire for their men to continue with Viagra treatment. A
        recently published study demonstrates that men taking Viagra with
        constant visual sexual stimulation reported a hard erection lasting on
        average for 33 minutes, compared to seven minutes for men on placebo. No
        other ED therapy has been proven to work better or faster than Viagra.

NEUROSCIENCE

Q13)    How is Aricept performing?

A13)    Aricept, approved for the treatment of symptoms of mild-to-moderate
        Alzheimer's disease (AD), continues to lead the AD market with a 59%
        worldwide market share and more than one billion cumulative patient days
        of therapy. Aricept is co-promoted with Eisai, the company that
        discovered the product. Entering its ninth year on the U.S. market,
        Aricept is the most prescribed treatment for AD, with new prescriptions
        maintained at around 28,000-30,000 per week. Total prescriptions are up
        14% versus 2004.

        Aricept's strong market leadership has been built on a large body of
        clinical evidence supporting its excellent efficacy and tolerability and
        a keen customer focus. About 10% of people over 65 suffer from AD,
        including 4.5 million Americans. Cognition -- including thinking,
        memory, and judgment -- is typically the first area affected by AD. The
        benefits of early intervention with Aricept were confirmed in a study
        published in December 2004 in the Archives of Neurology. In this 24-week
        study of patients with early-stage or mild AD, Aricept significantly
        improved cognitive performance compared with placebo.



        In February 2005, the National Institute of Clinical Excellence (NICE)
        in the U.K., issued a preliminary recommendation against the use of
        cholinesterase inhibitors. Advocacy groups, professional associations,
        patients, and caregivers have publicly criticized this recommendation.
        Eisai and Pfizer strongly disagree with NICE's recommendation and
        formally submitted a response on March 22, 2005. NICE is expected to
        issue final guidance in October 2005.

Q14)    How is Geodon performing?

A14)    Worldwide sales for Geodon totaled $138 million in the first quarter of
        2005, reflecting growth of 56% compared to the same period in 2004.
        Available in both an oral capsule and rapid-acting intramuscular
        formulation, Geodon is now launched in 49 countries, where more than
        five million prescriptions have been written for more than one million
        patients worldwide. In the U.S., weekly new- and total-prescription
        shares for Geodon continue to grow, achieving a new share high of 6.2%
        for new prescriptions in March 2005. The current growth rates of both
        new- and total-prescriptions for Geodon are more than five times the
        growth rate of the overall U.S. antipsychotic market. In addition,
        Germany and Spain enjoyed strong double-digit sales growth of 30% and
        45%, respectively, in the first quarter compared to the same period in
        2004.

        Schizophrenia affects approximately one in every 100 people and is among
        the most disabling of chronic mental illnesses, presenting in early
        adults and often persisting throughout adult life. In the selection of
        antipsychotics for schizophrenia, there is an increasing appreciation of
        metabolic effects. In the treatment of schizophrenia, clinical trials
        have demonstrated Geodon to be as effective as risperidone (Risperdal)
        and olanzapine (Zyprexa) in controlling both positive and negative
        symptoms, with a lower incidence of extra-pyramidal side effects than
        risperidone, and significantly less weight gain and adverse changes in
        other metabolic indices than olanzapine. In a head-to-head study versus
        olanzapine published in the October 2004 issue of the American Journal
        of Psychiatry, Geodon demonstrated efficacy equivalent to olanzapine in
        treating schizophrenia, while being associated with a lower incidence of
        weight gain and more favorable effects on lipids, triglycerides, and
        low-density lipoproteins. A head-to-head study comparing Geodon to
        risperidone in patients with schizophrenia or schizoaffective disorder
        was published in the December 2004 issue of the Journal of Clinical
        Psychiatry. This study found that Geodon improved psychotic symptoms,
        was generally well tolerated, and demonstrated less effect on prolactin
        and weight than risperidone. A one-year extension study of stable
        completers of a six-week trial of outpatients demonstrated that patients
        who were switched from olanzapine to Geodon sustained their weight loss,
        recorded significant improvement in lipid parameters and triglycerides,
        and maintained long-term improvement in their clinical symptoms. These
        data were presented at major psychiatry congresses in 2004 and are soon
        to be submitted for publication.

        On April 11, 2005, the FDA issued a request to manufacturers of all
        atypical antipsychotics to add a black-box warning to product labeling
        regarding increased mortality in patients with dementia- related
        psychosis, an indication for which Geodon is not approved. The request
        for this label change was based on meta-analyses of 17
        placebo-controlled trials of aripiprazole (Abilify), olanzapine
        (Zyprexa), risperidone (Risperdal), and quetiapine (Seroquel) in
        patients with dementia-related psychosis. Data for Geodon (ziprasidone)
        were not included. The results of these analyses reveal the risk ratio
        for death in the drug-treated patients compared to the placebo-treated
        patients of 1.6 to 1.7. The majority of deaths appeared to be
        cardiovascular or infectious in nature. Product labeling changes and a
        Dear Health Care Practitioner letter are expected soon.



        Risperidone, olanzapine, and aripiprazole already had bolded warnings in
        their labels indicating the increased mortality risk in elderly patients
        with dementia-related psychosis. It is anticipated that the addition of
        the black-box warning for all atypical antipsychotics may slow the rate
        of growth in elderly patients with dementia-related psychosis, affecting
        all agents. Less than 4% of Geodon's current use is in the elderly (over
        age 65) group of patients, and less than .3% in dementia patients.
        Geodon does not currently have extensive data or broad usage in the
        elderly population. Geodon is growing quickly in the core adult
        population. As part of Geodon's lifecycle management, Pfizer is focused
        on new indications for the core adult population in schizophrenia and
        bipolar disorder. Pfizer does not anticipate this warning will have a
        significant impact on Geodon's performance, nor will it prevent
        clinicians from using antipsychotic agents for primary indications.

Q15)    How is Lyrica (pregabalin) performing?

A15)    Worldwide sales of Lyrica totaled $20 million in the first quarter of
        2005. Lyrica is currently approved for various forms of neuropathic pain
        and as adjunctive therapy for partial epilepsy in 36 countries,
        including the E.U., and has been launched in 11 countries. The launches
        in Germany, the U.K., and Mexico represent the most successful
        introductions of any neuropathic-pain or adjunctive-epilepsy product to
        date. Strong initial adoption is attributable to the significant unmet
        medical need in both conditions, the compelling clinical evidence
        compiled in the Lyrica clinical program -- the largest ever for a
        neuroscience compound, with more than 9,000 patients in clinical trials
        -- and the positive initial results experienced by patients and
        physicians.

        Lyrica offers outstanding efficacy -- demonstrated by rapid, robust, and
        sustained pain reduction across its entire dose range of 150-600 mg --
        and favorable tolerability. Two critical studies presented at the
        American Pain Society meeting in March 2005 further support Lyrica's
        neuropathic-pain profile. One of these studies is the first ever
        demonstrating Lyrica's efficacy and tolerability in patients suffering
        from central neuropathic pain caused by spinal- cord injury. The other
        is an analysis of an ongoing open-label trial demonstrating Lyrica's
        efficacy in highly refractory neuropathic-pain patients who did not
        respond to at least three different treatments, including Neurontin
        (gabapentin). Recent publications also highlight Lyrica's efficacy in
        epilepsy, generalized anxiety disorder, and fibromyalgia, as well as its
        potential to improve sleep quality in healthy volunteers.

        In the U.S., Lyrica was approved on December 30, 2004, and is the first
        FDA-approved product for the treatment of neuropathic pain associated
        with both diabetic peripheral neuropathy and post- herpetic neuralgia.
        Pending the completion of a scheduling designation by the U.S.
        Department of Health and Human Services and the U.S. Drug Enforcement
        Administration, Lyrica is expected to be launched in the U.S. for these
        indications later in 2005. In September 2004, Lyrica received an
        approvable letter for adjunctive treatment of partial seizures in
        adults. Pfizer recently submitted a revised regulatory filing to the FDA
        for Lyrica's use in epilepsy, and this filing is under review.

Q16)    How is Neurontin performing?

A16)    Worldwide sales for Neurontin (gabapentin) totaled $182 million in the
        first quarter of 2005, reflecting a decline of 74% compared to the same
        period in 2004. This decline in sales is due to the at- risk launches
        last year of generic gabapentin products by Ivax, Alpharma, and Teva in
        the U.S. Pfizer's Greenstone subsidiary followed suit by launching its
        own generic version of gabapentin. Pfizer has sued these and other
        companies for patent infringement, and if the court determines that
        these companies have infringed Pfizer's Neurontin patent, Pfizer will
        seek all appropriate remedies and damages, including damages based on
        Pfizer's lost profits.



        Neurontin continues to be available in more than 100 countries and has
        been prescribed to more than 12 million patients since its initial
        approval in 1994. It is approved for adjunctive therapy in epilepsy in
        more than 100 countries and for treatment of a range of neuropathic-pain
        conditions in more than 60 countries.

Q17)    How is Relpax performing?

A17)    Worldwide sales of Relpax totaled $53 million in the first quarter of
        2005, reflecting growth of 77% compared to the same period in 2004.
        Launched in more than 25 countries, the product continues to gain market
        share in the $2.3 billion global oral triptan market. In the U.S.,
        Relpax achieved a 12% new-prescription share year-to- date through
        March, representing share growth of 65%, compared to the same period in
        2004. Relpax was launched in Canada, the fifth- largest triptan market,
        in November 2004.

        Recent data presented at the European Federation of Neurological
        Societies and the Migraine Trust International Symposium show that
        treating a migraine attack early, when the pain is still mild, with
        Relpax provides greater efficacy for migraine sufferers than waiting
        until the pain becomes more severe. The highest two-hour pain-free rates
        were seen among patients with mild pain taking Relpax 40 mg within 30
        minutes of pain onset. Sustained pain-free rates were higher for
        patients treated with Relpax 40 mg when the pain was mild versus
        moderate-to-severe. Published data also demonstrate that Relpax 40 mg
        provides better and more sustained relief from the symptoms of migraine
        than the market leader, sumatriptan (Imitrex), even if patients wait to
        treat and the pain is more severe. Relpax 40 mg also provides
        significantly more sustained relief than zolmitriptan (Zomig) or
        naratriptan (Amerge) based on two comparator studies. In addition,
        Relpax 40 mg has demonstrated efficacy in patients who have previously
        failed to obtain adequate relief with other prescription products or
        with over-the-counter migraine medications, such as Imitrex, Maxalt,
        Excedrin Migraine, non- steroidal anti-inflammatory drugs, and
        Fiorinal/Fioricet.

        The migraine market still represents a large untapped opportunity and a
        significant opportunity for continued Relpax growth. The prevalence of
        migraine is estimated to be 12% globally, with fewer than 50% of these
        patients being diagnosed and fewer than 20% receiving prescription
        medicine.

Q18)    How is Zoloft performing?

A18)    Worldwide sales of Zoloft totaled $845 million in the first quarter of
        2005, reflecting growth of 4% compared to the same period in 2004. It
        has been the most-prescribed antidepressant in the U.S. since 2000.
        Physicians have written approximately 250 million Zoloft prescriptions
        for a variety of psychiatric disorders, accounting for more than 13
        billion patient days of therapy. A large body of clinical data supports
        the product's safety and effectiveness in its indicated uses. Zoloft, in
        the U.S., is approved for six mood and anxiety disorders -- major
        depression, panic disorder, obsessive-compulsive disorder (OCD) in
        adults and children, post-traumatic stress disorder, pre-menstrual
        dysphoric disorder (PMDD), and social anxiety disorder. For each of
        these indications except PMDD, Zoloft is approved for both acute and
        long- term use.

        In the E.U., the Committee for Human Medicinal Products (CHMP) is
        conducting a review of 12 antidepressants, including Zoloft, regarding
        their use in children and adolescents. In February 2005, Pfizer provided
        a response to the review, and an assessment report from the CHMP is
        expected in the second quarter of 2005.

        In the U.S., in February 2005, Pfizer implemented FDA instructions that
        require the makers of all currently marketed antidepressants, including
        tricyclic agents, MAO inhibitors, selective serotonin reuptake
        inhibitors such as Zoloft, selective norepinephrine reuptake inhibitors,
        and atypical antidepressants, to include a black-box warning that
        antidepressants increased the risk of



        suicidal thinking and behavior in children and adolescents in pooled,
        short-term studies. In the nine completed clinical trials of Zoloft in
        pediatric and adolescent patients, which included studies of Zoloft in
        children diagnosed with depression, OCD, or both, no suicides occurred.
        The trials found no statistically significant differences between
        Zoloft-treated patients and placebo controls in their rates of suicide
        attempts or ideation.

Q19)    What is the status of asenapine?

A19)    Pfizer, through its collaboration with Organon, continues to advance the
        clinical development of asenapine, a novel psychotropic agent discovered
        by Organon and currently in Phase 3 studies. Asenapine is being studied
        in more than 3,000 patients for the treatment of the acute symptoms and
        maintenance therapy of schizophrenia, as well as for treatment of the
        acute manic episodes associated with bipolar disorder. Results of Phase
        2 results are encouraging and indicate that asenapine has demonstrated
        strong efficacy and good tolerability, with no clinically significant
        side effects. If approved, Pfizer and Organon plan to co-promote
        asenapine, which would enter a global antipsychotic market currently
        valued at more than $14 billion in annual sales and growing about 12%
        per year.

Q20)    What is the status of indiplon?

A20)    Indiplon is a novel GABA-A receptor potentiator being developed by
        Pfizer and Neurocrine Biosciences for the treatment of multiple aspects
        of insomnia. Neurocrine Biosciences has announced that it will resubmit
        U.S. regulatory filings for indiplon capsules and tablets during the
        second quarter of 2005. The clinical development program has
        demonstrated a compelling profile for the product: consolidation of
        sleep via sleep maintenance, fast onset of action, increased sleep
        duration, improved sleep quality, and no next-day sedation, tolerance,
        or rebound insomnia.

        Insomnia is a prevalent condition. In the U.S. alone, approximately 40%
        of the adult population report having trouble sleeping a few nights per
        week or more, according to the National Sleep Foundation's Sleep in
        America Poll 2002. Approximately 35% of the adult population reports
        that they have experienced insomnia every night or almost every night
        within the past year. Insomnia remains a disorder with high unmet
        medical needs, including problems of frequent night-time awakenings and
        difficulty falling back to sleep, sometimes referred to as sleep
        fragmentation. Fewer than 10% of patients are treated in this market.

ANTI-INFECTIVES

Q21)    How is Vfend performing?

A21)    Sales of the antifungal Vfend increased 38% to $88 million in the first
        quarter of 2005, compared to the same period in 2004. Strong growth has
        resulted from sustained demand and continuing product launches. Vfend
        has been launched in 51 countries, including the U.S. and most major
        overseas markets. It is now the leading hospital antifungal product in
        France and Germany.

        Vfend is a new-generation azole antifungal with an extended spectrum of
        activity against both yeasts and molds. The risk of serious fungal
        infections in hospitalized patients grows as more patients undergo bone
        marrow/stem cell and solid organ transplants, as well as aggressive
        chemotherapy for cancer and treatment for AIDS. Fungal infections in
        these immunocompromised patients are associated with high morbidity and
        mortality and require prompt and effective treatment. Vfend can be an
        important tool for physicians fighting these infections. Approved
        indications in the U.S. include primary treatment of acute invasive
        aspergillosis, salvage therapy for rare but serious fungal infections
        caused by the pathogens Scedosporium apiospermum and Fusarium spp.,
        treatment of esophageal candidiasis, and candidemia in non-neutropenic
        patients and the following Candida infections: disseminated infections
        in skin and infections in abdomen, kidney, bladder wall, and wounds
        (approved in December 2004).



        In Europe, Vfend is also approved for the treatment of serious,
        invasive, fluconazole-resistant Candida infections (including C. krusei)
        and first-line treatment of candidemia in non- neutropenic patients
        (approved in January 2005). Vfend is available as oral tablets, powder
        for oral suspension, and in an intravenous form. The main competing
        medicines can only be administered intravenously. In both tablet form
        and liquid suspension, Vfend shows excellent bioavailability. As a
        result, some patients may be discharged from the hospital sooner, with
        orally administered therapy continuing at home.

        Data from Pfizer Global Comparative Aspergillosis Study presented at the
        American Society of Hematology meeting in December 2004 demonstrated
        that patients with invasive aspergillosis who were treated with Vfend as
        primary therapy required fewer days of intensive care compared to
        patients receiving standard treatment. Data from the same study
        published in the Journal of Antimicrobial Chemotherapy indicated that
        Vfend as primary therapy provided both total treatment cost savings,
        resulting from reduced consumption of hospital resources and fewer
        changes in antifungal therapy, and better medical outcomes in terms of
        survival and safety compared with amphotericin B.

        Data on the efficacy and safety of long-term Vfend treatment for
        invasive aspergillosis with bone involvement were published in Clinical
        Infectious Diseases in April. This report represents the largest study
        of cases (20 cases) of bone aspergillosis treated with the same
        antifungal agent. Patients, most of whom were experiencing treatment
        failure or did not tolerate other antifungals, had a global response
        rate to Vfend of 55%.

Q22)    How is Zithromax performing?

A22)    Worldwide sales of Zithromax increased 71% to $797 million in the first
        quarter of 2005, compared to the same period in 2004. The global
        antibiotic sales declined 3% over this time frame. In the U.S.,
        Zithromax remains the number-one branded product in all key
        respiratory-tract-infection (RTI) indications, with more than three
        times as many prescriptions written as the second-leading branded
        competitor. Through the first quarter of 2005, Zithromax's U.S.
        new-prescription growth of 38% was more than twice the market growth,
        leveraging strong positioning relative to the competition as well as a
        strong RTI season.

        Zithromax continues to be used as first-line therapy for a number of key
        indications, including acute exacerbations of chronic bronchitis (AECB),
        community-acquired pneumonia (CAP), and acute bacterial sinusitis (ABS).
        Zithromax has a proven track record of clinical efficacy across the
        spectrum for mild to moderate RTI, an unsurpassed safety profile, and a
        short therapeutic course that may improve patient compliance.

        The regulatory filing for the new, single-dose azithromycin microspheres
        product is currently under review at the FDA. The filing includes
        indications for adult AECB, ABS, and CAP. To date, this product has also
        been filed for regulatory approval in 10 other countries around the
        world. This innovative technology makes it possible to deliver a single
        2-gram dose.

Q23)    How is Zyvox performing?

A23)    Worldwide sales of Zyvox totaled $143 million in the first quarter of
        2005, reflecting growth of 47% compared to the same period in 2004.
        While days of therapy for all anti-staphylococcal products have
        increased 15% worldwide in the past year, days of Zyvox therapy have
        increased more than 50%. The product is now marketed in 62 countries.



        The clinical value of Zyvox is growing, due to the rising incidence of
        infections caused by methicillin-resistant Staphylococcus aureus (MRSA)
        and multi-drug-resistant enterococci and their associated morbidity and
        mortality. Zyvox has proven efficacy in the treatment of patients with
        pneumonia and skin and soft-tissue infections, including diabetic foot
        infections, often caused by MRSA. The product has a unique mechanism of
        action that stops the initial stage of bacterial protein production,
        without which bacteria cannot multiply. This results in no
        cross-resistance with other antibiotics. Zyvox is available in
        intravenous and oral formulations. This allows for earlier discharge for
        some patients, who can switch from the intravenous Zyvox in the hospital
        to the oral form at home and thereby reduce their hospital costs. Zyvox
        is also approved for pediatric use.

        Published literature showing advantages of Zyvox continue to emerge. A
        post-hoc analysis of MRSA patients with surgical-site infections was
        published in the American Journal of Surgery in December 2004. Patients
        treated with Zyvox had microbiologic success rates of 87% compared to
        48% for patients on vancomycin. In January 2005, the American Thoracic
        Society and Infectious Diseases Society of America published new
        recommendations in their evidence-based guidelines for the management of
        adults with hospital-acquired pneumonia, ventilator-associated pneumonia
        (VAP), and healthcare-associated pneumonia, positioning Zyvox as an
        alternative to the market volume leader, vancomycin, based on
        preliminary data suggesting Zyvox may have an advantage for proven VAP
        cases due to MRSA.

Q24)    What is the status of maraviroc (UK-427,857)?

A24)    Maraviroc is in Phase 3 clinical development for the treatment, in
        combination with other antiretroviral agents, of patients with HIV
        infection. A CCR-5 antagonist, maraviroc belongs to a new group of HIV
        antiretrovirals known as entry inhibitors that work extracellularly to
        block the HIV virus from gaining entry into the cell. It has been shown
        in vitro to be effective against HIV strains resistant to the current
        classes of HIV antiretroviral agents, potentially addressing a
        significant unmet medical need in HIV therapy. Phase 1 studies have
        shown maraviroc to be well tolerated across a range of potential doses,
        and efficacy and safety have been studied in Phase 2 monotherapy trials
        in HIV patients.

        The global HIV/AIDS epidemic killed more than 3 million people in 2003.
        An estimated 5 million people acquired HIV during the year, bringing to
        38 million the number of people living with the virus around the world
        (UNAIDS Report, July 2004). Worldwide sales of antiretroviral products
        in 2004 totaled just under $7.3 billion and are anticipated to grow to
        $10 billion by 2009.

OPHTHALMOLOGY

Q25)    How is Xalatan/Xalacom performing?

A25)    Sales of Xalatan/Xalacom totaled $333 million in the first quarter of
        2005, reflecting growth of 19% compared to the same period in 2004.
        Xalatan/Xalacom are the leading brands in sales in the glaucoma market
        and are outperforming all competitors in market- share gain.

        Worldwide, an estimated 67 million people suffer from glaucoma, a group
        of eye diseases characterized by damage to the optic nerve, visual-field
        loss, and elevated intraocular pressure (IOP). Each year, more than
        100,000 people in the U.S. are diagnosed with glaucoma. In the U.S.,
        approximately one third of the diagnosed glaucoma patients are
        untreated, and only 10-15% of the ocular hypertensive patients receive
        treatment. Xalatan, a prostaglandin analogue used to lower the
        intraocular pressure associated with glaucoma and ocular hypertension,
        continues to lead the worldwide anti-glaucoma market and has displaced
        beta blockers as the accepted gold standard. It provides comprehensive
        IOP management by combining the benefits of product efficacy,
        tolerability, patient persistency, and five-year safety data. Effective
        IOP management has been shown to prevent or delay optic-nerve damage
        from glaucoma that can lead to blindness. Xalacom, a combination of
        Xalatan and the beta blocker timolol, provides incremental efficacy for
        patients who have an insufficient response to monotherapy while
        maintaining the simplicity of a single daily dose.



        An article published in the September 2004 issue of the American Journal
        of Ophthalmology compared the nocturnal effects of the once- daily beta
        blocker timolol and Xalatan on IOP in a small number of patients with
        ocular hypertension or early glaucomatous changes. Both treatments were
        effective in lowering IOP during the day. Xalatan also reduced IOP at
        night. No statistically significant difference was found in the
        nocturnal IOP between timolol treatment and no medication. Raised IOP is
        a risk factor for glaucoma progression, and thus control of IOP, both
        day and night, is critical for the control of glaucoma.

        Publication of the European Glaucoma Prevention Study in Ophthalmology
        in March 2005 expands the evidence supporting the need for effective
        medical therapy to treat ocular hypertension and to delay progression to
        glaucoma. An article published in the September 2004 issue of the
        American Journal of Ophthalmology addresses physicians' decisions about
        when to treat an ocular- hypertensive patient. The article establishes
        the concept of global risk assessment and supports early initiation of
        treatment in ocular-hypertensive patients. As in cardiovascular disease,
        the concept of global risk assessment, when applied to glaucoma, may
        enable ophthalmologists to identify and treat glaucoma patients earlier.

Q26)    What is the status of Macugen?

A26)    In December 2004, the FDA approved Macugen for the treatment of
        neovascular (wet) age-related macular degeneration. Pfizer and Eyetech
        Pharmaceuticals, Inc., the discoverer of Macugen, launched the product
        in the U.S. in January 2005. Macugen has also been filed in the E.U.,
        Canada, Australia, Switzerland, and Brazil.

        Macugen is an aptamer that selectively binds to, and neutralizes,
        vascular endothelial growth factor (VEGF) for the treatment of age-
        related macular degeneration (AMD). AMD is the leading cause of
        irreversible vision loss among Americans over 55 and occurs in both wet
        and dry forms. In wet AMD, blood vessels grow abnormally into the area
        beneath the retina.

        Positive Phase 3 results from the VEGF Inhibition Study in the Ocular
        Neovascularization (VISION) trial were published in the December 30,
        2004, issue of the New England Journal of Medicine. This study
        demonstrated that Macugen is an effective and well- tolerated treatment
        for a broad group of wet AMD patients irrespective of lesion subtype or
        size, unlike existing therapies.

        Macugen is now reimbursed by Medicare carriers covering all 50 states in
        the U.S., all according to the broad FDA label without restrictions.
        Pfizer and Eyetech have also developed a Macugen Access Program(TM)
        (MAP), which is now available to physicians and patients for additional
        support in gaining access to, or reimbursement for, Macugen. MAP offers
        pre-treatment and post- treatment services such as insurance
        verification, authorization assistance, claims and reviews tracking,
        denials and appeal assistance, and patient assistance programs.

ARTHRITIS AND PAIN

Q27)    What recent regulatory actions have been taken concerning the safety of
        prescription and over-the-counter non-steroidal anti-inflammatory drugs
        (NSAIDs), including COX-2-specific medicines?

A27)    The FDA Arthritis and Drugs Safety Committee and the Risk Management
        Advisory Committee met jointly on February 16-18 to review COX-2-
        specific inhibitors and other non-steroidal anti-inflammatory drugs
        (NSAIDs). After evaluating a substantial body of clinical data regarding
        Celebrex and Bextra and weighing the benefits and risks of these
        products, the advisory committees recommended to the FDA that these
        medicines remain available to patients with revised labeling.



        On April 7, 2005, the FDA announced its plans for changes to the
        warnings sections of labels of NSAIDs, including COX-2 medicines, sold
        either by prescription or over-the-counter. These labeling changes will
        include boxed warnings for prescription NSAIDs regarding potential
        cardiovascular, gastrointestinal, and skin- reaction risks. Pfizer will
        continue to work closely with the FDA to implement labeling revisions
        for Celebrex that ensure its appropriate prescribing and use.

        The FDA also requested the suspension of Bextra sales and marketing,
        based on its assessment of an unfavorable risk/benefit profile due to
        the additional increased risk of rare, serious skin reactions compared
        to other NSAIDs, including Celebrex. While Pfizer disagrees with this
        assessment of Bextra, it has respectfully complied with the FDA's
        request and began the process of suspending Bextra sales on April 7.
        Discussions between Pfizer and the EMEA, Health Canada, and several
        other regulatory agencies in early April have led to similar regulatory
        requests regarding Bextra. Pfizer, while disagreeing with these
        agencies, has complied with their requests for suspension of sales and
        marketing of Bextra.

Q28)    What is Pfizer's position on Celebrex?

A28)    In keeping with the FDA's position, Pfizer is advising physicians to
        consider the evolving information in evaluating the risks and benefits
        of all NSAIDs, including its COX-2-selective medicine Celebrex. While
        awaiting final labeling from the FDA, physicians should consider the
        available data on all these medicines when assessing individual patients
        to be treated for osteoarthritis, rheumatoid arthritis, or acute pain.
        Factors to be considered include information concerning the existing
        body of data, the risks of alternative treatments, and the individual
        patient's underlying cardiovascular and gastrointestinal risk status. As
        with all prescription NSAIDs, Celebrex should be used at the lowest
        effective dose for the shortest duration, consistent with individual
        patient treatment goals.

ONCOLOGY

Q29)    How is Aromasin performing?

A29)    Sales of Aromasin totaled $55 million in the first quarter of 2005,
        reflecting growth of 134% compared to the same period in 2004. This
        growth can be attributed primarily to data in the early breast- cancer
        setting for Aromasin and the increasing awareness of the utility of
        aromatase inhibitors, the class to which Aromasin belongs. In addition,
        updated efficacy data on Aromasin were presented in December 2004 at the
        San Antonio Breast Cancer Symposium, showing an improving trend toward
        overall survival for Aromasin-treated patients in the Intergroup
        Exemestane Study (IES). The American Society for Clinical Oncology and
        the National Comprehensive Cancer Network recently updated adjuvant
        treatment guidelines, endorsing the use of aromatase inhibitors,
        including Aromasin, in the treatment of early breast cancer.

        Pfizer submitted a supplemental regulatory filing in December 2004 in
        both the U.S. and the E.U. for an adjuvant indication for Aromasin.
        Based on the pivotal IES trial, this would allow Aromasin to be used in
        the estimated 500,000 breast-cancer patients currently on tamoxifen for
        two to three years. The study showed a 32% better probability of
        disease-free survival and a 37% better probability for
        breast-cancer-free survival for patients switched to Aromasin.
        Statistically significant risk reductions were also shown for
        distant-recurrence, contralateral breast cancer and serious events such
        as the development of non-breast primary cancers and thromboembolism.



Q30)    How is Campto/Camptosar performing?

A30)    Sales of Campto/Camptosar totaled $212 million in the first quarter of
        2005, reflecting growth of 132% compared to the same period in 2004.
        Sales growth was impacted in part by Pfizer's acquisition of marketing
        rights to Campto/ Camptosar in Europe and Asia (except Japan) in late
        2004. In the U.S., total metastatic colorectal- cancer (CRC) patient
        share totaled nearly 30% in January 2005, narrowing the share gap with
        Eloxatin to about five percentage points.

        The worldwide presence of Campto/Camptosar has driven the growth of this
        cytotoxic drug. Campto/Camptosar continues to be the backbone of
        metastatic CRC treatment. When used in combination with the newly
        introduced targeted agents like Avastin, Campto/Camptosar with
        5-fluorouracil (5FU) and leucovorin (LV) is the only regimen that has
        demonstrated a survival benefit for patients in first-line metastatic
        CRC. Campto/Camptosar and 5FU/LV are the only drugs approved to be used
        in combination with the other newly introduced targeted therapy Erbitux
        in second-line treatment. Campto/Camptosar has also demonstrated a
        survival benefit when compared with 5FU/LV alone. The overall survival
        rate for patients with metastatic CRC has almost doubled since the
        introduction of Campto/Camptosar in 1999.

Q31)    What is the status of Sutent (SU-11248)?

A31)    Sutent, or SU-11248, is a breakthrough oral anti-cancer product
        candidate that targets tumors both by cutting off blood supply to the
        tumor and by directly killing tumor cells. It has shown unprecedented
        activity in clinical trials involving patients with advanced
        gastrointestinal stromal tumors and renal cell carcinoma who did not
        respond to, or could not tolerate, standard treatment options. At the
        upcoming American Society of Clinical Oncology meeting in May, Pfizer
        anticipates presentation of exploratory clinical research involving
        Sutent in other major tumor types.

OSTEOPOROSIS

Q32)    What is the status of Oporia (lasofoxifene)?

A32)    Oporia (lasofoxifene) is a selective estrogen receptor modulator (SERM)
        under development for the prevention and treatment of osteoporosis and
        for the treatment of vaginal atrophy. The U.S. regulatory filing for
        osteoporosis prevention was submitted in August 2004, and a supplemental
        filing for the treatment of vaginal atrophy was submitted in December
        2004. Regulatory submissions in other markets are expected in 2005.
        Osteoporosis affects some 8 million American women. An additional 22
        million women are estimated to have low bone mass, placing them at
        increased risk of osteoporosis. In the U.S., osteoporosis is responsible
        for more than 1.5 million fractures per year. Vaginal dryness becomes
        increasingly more common throughout the menopausal transition. SERMs may
        offer benefits beyond just the bone effects provided by other treatment
        options, such as bisphosphonates.

ANIMAL HEALTH

Q33)    How did Pfizer's Animal Health business perform?

A33)    Sales of the Animal Health business totaled $496 million in the first
        quarter of 2005, reflecting growth of 16% compared to the same period in
        2004. These results were driven by solid growth of Draxxin, cattle
        biologicals, and other livestock products and by the companion-animal
        products Rimadyl and Revolution and small-animal biological products, as
        well as the favorable impact of a weaker U.S. dollar relative to the
        prior year. Pfizer Animal Health is the world leader in providing
        products to prevent and treat diseases in animals.



CONSUMER HEALTHCARE

Q34)    How did Pfizer's Consumer Healthcare business perform?

A34)    Sales of the Consumer Healthcare business totaled to $945 million in the
        first quarter of 2005, reflecting growth of 17% compared to the same
        period in 2004. These results reflect sustained sales strength for
        Listerine mouthwash, which benefited from the launch of Listerine
        Advanced in September 2004; growth from Sudafed and other
        upper-respiratory products, Zantac, and tobacco-dependence products; and
        a weaker U.S. dollar relative to the prior year.

FINANCIAL MATTERS

Q35)    How were first-quarter revenues impacted by Pfizer's accounting
        calendar?

A35)    Pfizer's U.S. fiscal year runs from January 1 through December 31, and
        its international fiscal year runs from December 1 to November 30. The
        start dates of the second, third, and fourth quarters and ending dates
        of the first, second, and third quarters can vary slightly from year to
        year because Pfizer's quarterly accounting calendar closes on the Sunday
        in closest proximity to the end of the calendar quarter, not the
        calendar quarter-end. This practice resulted in three additional
        business days in the first quarter relative to 2004. Pfizer's second and
        third fiscal quarters of 2005 have the same number of business days as
        the prior year. The fiscal fourth quarter of 2005, however, has four
        fewer business days than the prior year.

Q36)    What impact did foreign exchange have on revenues in the quarter?

A36)    The weakening of the U.S. dollar relative to other currencies,
        principally the euro, Japanese yen, British pound, and Canadian dollar,
        favorably impacted revenues in the first quarter of 2005 by $399 million
        and favorably impacted consolidated revenue growth by about three
        percentage points.

Q37)    What cost synergies from the Pharmacia acquisition were achieved in the
        first quarter? What costs to achieve these synergies are expected?

A37)    Cost synergies resulting from the acquisition of Pharmacia exceeded $1
        billion in the first quarter of 2005. Our estimate for full-year 2005
        synergies remains $4.2 billion. Synergies stem from a broad range of
        sources, including a streamlined organization, reduced operating
        expenses, and procurement savings. Merger-related expenditures (income
        statement and balance sheet) incurred during 2003-2005 to achieve these
        synergies continue to be expected at about $6 billion.

Q38)    What caused cost of sales to increase by 22% in the first quarter of
        2005, compared to the first quarter of 2004, given the revenue increase
        of 5%?

A38)    Cost of sales as a percentage of revenues in the first quarter of 2005
        was adversely impacted by changes in production volume, as well as
        geographic, segment, and product mix, reflecting the loss of exclusivity
        of certain major products in the U.S. and lower year- over-year sales of
        COX-2 products, compared to the first quarter of 2004 and charges for
        write-offs of inventory related to the suspension of Bextra sales. Cost
        of sales as a percentage of revenues will remain under pressure in 2005.

Q39)    What factors affected the 7% increase in research and development
        expenses in the first quarter of 2005?

A39)    During the transitional year of 2005, Pfizer will sustain both the
        capability and will to make those investments necessary to support
        long-term growth. R&D spending increased 7% in the quarter, reflecting
        this commitment to continued investment, the advancement of the
        portfolio, and the unfavorable impact of foreign exchange. Full-year
        2005 R&D spending is expected to be approximately $8 billion.



Q40)    What impact did the suspension of sales of Bextra, announced on April 7,
        2005, have on first-quarter results? What is the anticipated impact on
        Celebrex sales from the product's additional labeling information?

A40)    The suspension of sales of Bextra in the U.S., E.U., and other markets
        in early April is expected to reduce our previously announced targeted
        full-year 2005 adjusted and reported diluted EPS* by approximately $.05
        per share. Also in connection with the decision to suspend sales of
        Bextra, Pfizer recorded certain charges totaling $1.213 billion ($766
        million net of tax, or $.10 per share) in the first quarter of 2005.
        These pre-tax charges included $1.145 billion related to the impairment
        of Bextra's intangible assets for developed technology rights, $10
        million related to the write-off of machinery and equipment, $56 million
        in write-offs of inventory, and $2 million related to the costs of
        administering the suspension of sales. In addition, we recorded in the
        first quarter of 2005 a net charge of $71 million, substantially against
        revenues, for estimated customer returns of Bextra.

        The market for pain relievers has shown considerable change since the
        withdrawal of Vioxx in September 2004. Following the FDA and EMEA
        regulatory reviews of these medicines in February 2005, the market for
        prescription pain relievers, including Celebrex, indicated lower, but
        stabilizing, sales levels compared to pre-Vioxx withdrawal levels. We do
        not expect the additional labeling information for Celebrex to further
        impact 2005 revenues due to anticipated switching by patients among pain
        relievers, including those previously using Bextra.

Q41)    What were the principal factors affecting pre-tax other (income)/
        deductions-net?

A41)                                                           First Quarter

        Other (Income)/Deductions--Net                       $ 1,038    $   (43)

        In connection with the decision to suspend sales of Bextra, we recorded
        a charge of $1.145 billion relating to the impairment of Bextra's
        intangible assets for developed technology rights and the write-off of
        machinery and equipment of $10 million.

Q42)    What is Pfizer's projected effective tax rate for 2005?

A42)    Pfizer's effective tax rate in calculating adjusted income* from
        continuing operations for 2005 is projected to be 23%. This is the same
        rate recorded for the first quarter of 2004. The difference between the
        23% rate projected for 2005 and the 21.75% rate recorded for full-year
        2004 relates mainly to changes in geographic and product mix.

Q43)    What was the impact of Pfizer's decision to repatriate cash from foreign
        earnings?

A43)    In the first quarter of 2005, we decided to repatriate cash from foreign
        earnings totaling $28.3 billion during 2005 in accordance with the
        American Jobs Creation Act of 2004, and we recorded a related tax charge
        of $2.2 billion. This tax charge may be reduced by approximately $850
        million in future periods due to technical corrections legislation
        expected to be considered by Congress in 2005.



Q44)    What is the status of planned divestitures?

A44)    In the first quarter of 2004, Pfizer announced its intention to divest
        the legacy Pharmacia in-vitro allergy and autoimmune diagnostic testing
        business; the legacy Pharmacia surgical ophthalmology business, certain
        legacy Pfizer and Pharmacia non-core European over-the-counter and
        personal-care product lines; and three legacy Pharmacia European generic
        businesses. First-quarter net income from discontinued operations of $29
        million reflects the gain on the sale of one of the two remaining
        European generic businesses, less a loss from operations of these
        businesses prior to their sale.

Q45)    What is the status of Pfizer's share-purchase program?

A45)    Pfizer's financial strength and flexibility have allowed the Company to
        purchase its stock over the past several years. We believe that purchase
        of our stock is an excellent investment opportunity. During the past six
        years, Pfizer has purchased more than $30 billion of its common stock.
        In October 2004, Pfizer announced a new authorization to purchase up to
        $5 billion of the company's common stock. During the first quarter of
        2005, the company purchased approximately 36 million shares at a total
        cost of about $919 million under this authorization. The company has
        purchased approximately 99 million shares at a total cost of about $2.6
        billion under this authorization. In light of Pfizer's financial
        strength and cash flow, we will accelerate and complete our current
        share-purchase program in the second quarter by purchasing approximately
        $2.4 billion of the company's stock in this quarter alone, and early in
        the second half we will consider additional opportunities to purchase
        the company's stock.

Q46)    Why does Pfizer disclose adjusted income* and adjusted diluted EPS*?

A46)    General Description of Adjusted Income Measure

        Adjusted Income is an alternative view of performance used by management
        and we believe that investors' understanding of our performance is
        enhanced by disclosing this performance measure. The company reports
        Adjusted Income in order to portray the results of our major operations
        -- the discovery, development, manufacture, marketing, and sale of
        prescription medicines for humans and animals, as well as our
        over-the-counter products, prior to considering certain income-statement
        elements. We have defined Adjusted Income as net income before
        discontinued operations, significant impacts of purchase accounting for
        acquisitions, merger- related costs, and certain significant items. The
        Adjusted Income measure is not, and should not be, viewed as a
        substitute for U.S. GAAP Net Income.

        The Adjusted Income measure is an important internal measurement for
        Pfizer. We measure performance of the overall company on this basis. The
        following are examples of how the Adjusted Income measure is utilized:

    *   Senior management receives a monthly analysis of the operating results
        of our company that is prepared on an Adjusted Income basis;

    *   The annual budgets of our company are prepared on an Adjusted Income
        basis; and

    *   Annual and long-term compensation, including annual cash bonuses,
        merit-based salary adjustments, and stock options, for various levels of
        management is based on financial measures that include Adjusted Income.
        The Adjusted Income measure currently represents a significant portion
        of target objectives that are utilized to determine the annual
        compensation for various levels of management, although the actual
        weighting of the objective may vary by level of management and job
        responsibility, and may be considered in the determination of certain
        long-term compensation plans. The portion of senior management's bonus,
        merit-based salary increase, and equity-compensation awards based on the
        Adjusted Income measure ranges from 10% to 30%.



        Despite the importance of this measure to management in goal setting and
        performance measurement, we stress that Adjusted Income is a non-GAAP
        financial measure that has no standardized meaning prescribed by U.S.
        GAAP and, therefore, has limits in its usefulness to investors. Because
        of its non-standardized definition, Adjusted Income (unlike U.S. GAAP
        Net Income) may not be comparable with the calculation of similar
        measures for other companies. Adjusted Income is presented solely to
        permit investors to more fully understand how management assesses the
        performance of our company.

        We also recognize that, as an internal measure of performance, the
        Adjusted Income measure has limitations and we do not restrict our
        performance-management process solely to this metric. A limitation of
        the Adjusted Income measure is that it provides a view of operations
        without including all events during a period, such as the effects of an
        acquisition, merger-related or other restructuring charges, or
        amortization of purchased intangibles, and does not provide a comparable
        view of our performance to other companies in the pharmaceutical
        industry. We also use other specifically tailored tools designed to
        ensure the highest levels of performance in the company. For example,
        our Research and Development organization has productivity targets, upon
        which its effectiveness is measured. In addition, for senior levels of
        management, a portion of their long-term compensation is based on U.S.
        GAAP net income.

        Purchase-Accounting Adjustments

        Adjusted Income is calculated prior to considering significant
        purchase-accounting impacts, such as those related to our acquisitions
        of Pharmacia and Esperion as well as net-asset acquisitions. These
        impacts can include charges for purchased in- process research and
        development, the incremental charge to cost of sales from the sale of
        acquired inventory that was written up to fair value, and the
        incremental charges related to the amortization of finite-lived
        intangible assets for the increase to fair value. Therefore, the
        Adjusted Income measure includes the revenues earned upon the sale of
        the acquired products without considering the aforementioned significant
        charges.

        Certain of the purchase-accounting adjustments associated with a
        business combination or a net-asset acquisition, such as the
        amortization of intangibles acquired in connection with our acquisition
        of Pharmacia, can occur for up to 40 years (these assets have a
        weighted-average useful life of approximately 10 years), but this
        presentation provides an alternative view of our performance that is
        used by management to internally assess business performance. We believe
        the elimination of amortization attributable to acquired intangible
        assets provides management and investors an alternative view of our
        business results by trying to provide a degree of parity to internally
        developed intangible assets for which research and development costs
        have been previously expensed.

        However, a completely accurate comparison of internally developed
        intangible assets and acquired intangible assets cannot be achieved
        through Adjusted Income. This component of Adjusted Income is derived
        solely with the impacts of the items listed in the first paragraph of
        this section. We have not factored in the impacts of any other
        differences in experience that might have occurred if Pfizer had
        discovered and developed those intangible assets on its own, and this
        approach does not intend to be representative of the results that would
        have occurred in those circumstances. For example, our research and
        development costs in total, and in the periods presented, may have been
        different; our speed to commercialization and resulting sales, if any,
        may have been different; or our costs to manufacture may have been
        different. In addition, our marketing efforts may have been received
        differently by our customers. As such, in total, there can be no
        assurance that our Adjusted Income amounts would have been the same as
        presented had Pfizer discovered and developed the acquired intangible
        assets.



        Merger-Related Costs

        Adjusted Income is calculated prior to considering integration and
        restructuring costs associated with business combinations because these
        costs are unique to each transaction and represent costs that were
        incurred to restructure and integrate two businesses as a result of the
        acquisition decision. For additional clarity, only restructuring and
        integration activities that are associated with a purchase business
        combination or a net-asset acquisition are included in merger-related
        costs. We have not factored in the impacts on synergies that would have
        resulted had these costs not been incurred.

        We believe that viewing income prior to considering these charges
        provides investors with a useful additional perspective because the
        significant costs incurred in a business combination or net-asset
        acquisition result primarily from the need to eliminate duplicate
        assets, activities, or employees-a natural result of acquiring a fully
        integrated set of activities. For this reason, we believe that the costs
        incurred to convert disparate systems, to close duplicative facilities,
        or to eliminate duplicate positions (for example, in the context of a
        business combination) can be viewed differently from those costs
        incurred in other, more normal business contexts.

        The integration and restructuring costs associated with a business
        combination may occur over several years with the most significant
        impacts ending within three years of the transaction. Because of the
        need for certain external approvals for some actions, the span of time
        needed to achieve certain restructuring and integration activities can
        be lengthy. For example, due to the highly regulated nature of the
        pharmaceutical business, the closure of excess facilities can take
        several years, as all manufacturing changes are subject to extensive
        validation and testing and must be approved by the FDA. In other
        situations, we may be required by local laws to obtain approvals prior
        to terminating certain employees. This approval process can delay the
        termination action.

        Discontinued Operations

        Adjusted Income is calculated prior to considering gains or losses on
        the sale of businesses and product lines included in discontinued
        operations as well as the related results of operations. We believe that
        this presentation is meaningful to investors because, while we review
        our businesses and product lines on an ongoing basis for strategic fit
        with our operations, we do not build or run our businesses with an
        intent to sell them.

        Certain Significant Items

        Adjusted Income is calculated prior to considering certain significant
        items. Certain significant items represent substantive, unusual items
        that are evaluated on an individual basis. Such evaluation considers
        both the quantitative and the qualitative aspect of their unusual
        nature. Unusual, in this context, may represent items that are not part
        of our ongoing business; items that, either as a result of their nature
        or size, we would not expect to occur as part of our normal business on
        a regular basis; items that would be non-recurring; or items that relate
        to products we no longer sell. While not all-inclusive, examples of
        items that could be included as certain significant items would be a
        major non- acquisition-related restructuring charge, if non-recurring in
        nature, such as those related to our recently announced productivity
        initiative; costs associated with a significant recall of one of our
        products, such as costs related to our suspension of sales of Bextra
        (such costs would not reflect customer returns); charges related to
        sales or disposals of products or facilities that do not qualify as
        discontinued operations as defined by U.S. GAAP; certain intangible-
        asset impairments; the impact of certain significant tax legislation,
        such as charges attributable to the repatriation of foreign earnings in
        accordance with the American Jobs Creation Act of 2004; or possible
        charges related to legal matters, such as those discussed in Legal
        Proceedings in our Form 10-K and in Part II: Other Information; Legal
        Proceedings included in our Form 10-Q filings. Normal, ongoing defense
        costs of the company or settlements and accruals on legal matters made
        in the normal course of our business would not be considered a certain
        significant item.



Q47)    What are Pfizer's financial expectations for 2005-07?

A47)    We expect 2005 to be a transition year for Pfizer due to a number of
        factors. Results in 2005 are being, and will continue to be, impacted by
        loss of U.S. exclusivity of four major products- Diflucan, Neurontin,
        and Accupril during 2004 and Zithromax in 2005. Revenues also have been,
        and will continue to be, impacted by publicity and regulatory actions
        regarding COX-2-selective inhibitors. Full-year revenues are expected to
        be substantially unchanged from 2004, as growth from other product lines
        generally offsets these factors. The suspension of sales of Bextra in
        the U.S., E.U., and other markets in early April is expected to reduce
        our previously announced targeted full-year 2005 adjusted and reported
        diluted EPS* by approximately $.05 per share. Bextra asset write-offs
        are expected to reduce our previously announced targeted full-year 2005
        reported diluted EPS by an additional $.10 per share. However, 2005
        results are no longer expected to be impacted by the adoption of new
        accounting regulations relating to the expensing of stock options,
        pursuant to a deferral in the implementation date of the new
        regulations, as announced by the SEC last week. These regulations had
        been expected to result in an after-tax expense reducing 2005 adjusted
        and reported diluted EPS* by $.03 per share. Pfizer expects to implement
        SFAS 123R regarding expensing of stock options as of January 1, 2006.
        From an efficiency perspective, in 2005 we continue to anticipate
        Pharmacia merger-related synergies of $4.2 billion this year, an
        increase of $600 million over 2004 Pharmacia merger-related synergies.
        Pfizer will also achieve modest cost savings during 2005 from its newly
        announced productivity initiative. Given these and other factors, we
        expect 2005 adjusted income* of approximately $14.7 billion, adjusted
        diluted EPS* of approximately $1.98 per share, reported income of $7.7
        billion, and reported diluted EPS of approximately $1.04 per share,
        subject to the Disclosure Notice in this report.

        The differences between targeted 2005 adjusted income* and adjusted
        diluted EPS* and 2005 reported income and reported diluted EPS are
        attributable to anticipated non-cash charges of $2.6 billion ($.36 per
        share) relating to purchase accounting for the acquisition of Pharmacia
        and an in-process research and development charge relating to our
        recently completed acquisition of Idun Pharmaceuticals, Inc.;
        merger-related and restructuring costs of $1.4 billion ($.18 per share),
        which include both Pharmacia-related charges and charges related to the
        recently announced planned productivity initiative; and charges relating
        to the suspension of sales of Bextra of $.8 billion ($.10 per share),
        all on an after-tax basis. In addition, reported net income for 2005
        will include a tax charge of $2.2 billion ($.30 per share) relating to
        the cash repatriation of foreign earnings in 2005, with a possible
        subsequent reduction of this charge by about $850 million, due to
        anticipated technical corrections legislation. All of these estimates
        are subject to the variables cited in the Disclosure Notice found in
        this report.

        We will sustain both the capability and will to make those investments
        necessary to support long-term growth. Pfizer's financial strength
        remains unprecedented and will be enhanced by the cash repatriation of
        $28.3 billion in foreign earnings during this year. With the current
        quarterly dividend of $.19 per share, which is 12% higher than last
        year, we are continuing the company's commitment to strong growth in
        dividends, both today and in the future. We will accelerate and complete
        our current share-purchase program in the second quarter by purchasing
        approximately $2.4 billion of the company's stock in this quarter, and
        early in the second half we will consider additional opportunities to
        purchase the company's stock.



        A number of factors are expected to drive a return to double-digit
        adjusted earnings* growth in 2006. We are undertaking a new, broad-
        based, multi-year productivity initiative to increase efficiency and
        effectiveness of all operations company-wide. Annual savings are
        projected to total $4 billion by 2008. Improved revenue performance is
        also anticipated, as many of our in-line products continue to grow, we
        experience renewed growth of Celebrex, and the contribution of new
        products increases.

        Revenue growth, enhanced by continuing productivity initiatives, is
        expected to drive a strong 2007, when we anticipate accelerating
        double-digit adjusted earnings* growth.
