Note 1. Summary of Significant Accounting Policies
------------------------------------------

The following policies are required interim updates to those disclosed
in Footnote 1 of the 2002 Annual Report on Form 10-K:

Stock-Based Compensation: The Company has five Stock Incentive Plans
which it accounts for using the intrinsic value method in accordance
with APB Opinion No. 25, Accounting for Stock Issued to Employees. No
stock-based employee compensation cost is reflected in net income, as
all options granted under those plans had an exercise price equal to
the market value of the underlying common stock on the date of grant.
The following table illustrates the effect on net income and earnings
per share if the Company had applied the fair value recognition
provisions of SFAS No. 123, Accounting for Stock-Based Compensation,
to stock-based employee compensation:

Goodwill and Other Intangibles: On January 1, 2002, the Company
adopted SFAS No. 142, Goodwill and Other Intangible Assets. With the
adoption of SFAS No. 142, goodwill is no longer being amortized but is
subject to at least an annual assessment for impairment by applying a
fair value-based test. The same applies to other intangibles that have
been determined to have indefinite useful lives. However, other
intangibles with finite lives will continue to be amortized. The
Company's other intangibles, which all have finite lives, are being
amortized over their estimated useful lives ranging from three to 10
years.

Note 2. Issuance of Notes and Credit Facilities
---------------------------------------

Issuance of $1,800.0 Million of Notes:

On February 11, 2003, the Company issued $1,800.0 million of Notes.
The issuance consisted of two tranches of Notes, each of which pays
interest semiannually, as follows:

o $300.0 million 4.125% Notes due March 1, 2008 with interest
payments due on March 1 and September 1

o $1,500.0 million 5.25% Notes due March 15, 2013 with
interest payments due on March 15 and September 15

The interest rate payable on each of these tranches of Notes is
subject to an increase of 0.25 percentage points per level of
downgrade in the Company's credit rating by Moody's or S&P. There is
no adjustment to the interest rate payable on either series of Notes
for the first single-level downgrade in the Company's credit rating by
S&P. If Moody's or S&P subsequently were to increase the Company's
credit rating, the interest rate payable on each series of Notes is
subject to a decrease of 0.25 percentage points for each level of
credit rating increase. The interest rate payable for both series of
Notes cannot be reduced below the original coupon rate of either
series of Notes. However, the total adjustment to the interest rate
for either series of Notes cannot exceed two percentage points and the
interest rate in effect on March 15, 2006, for both series of Notes,
will become the effective interest rate until maturity. The Company
would incur a total of approximately $4.5 million of additional annual
interest expense for every 0.25 percentage point increase in the
interest rate.

The Company entered into two interest rate swaps with an aggregate
notional amount of $300.0 million relating to the $300.0 million
4.125% Notes and two interest rate swaps with an aggregate notional
amount of $1,500.0 million relating to the $1,500.0 million 5.25%
Notes whereby the Company effectively converted the fixed rate of
interest on these Notes to a floating rate, which is based on LIBOR.

New Credit Facility:

In March 2003, the Company's $3,000.0 million credit facility matured.
Concurrent with this maturity, the Company entered into new credit
facilities totaling $2,700.0 million. These credit facilities are
composed of a $1,350.0 million, 364-day facility and a $1,350.0
million three-year facility. The maturity date of any borrowings under
the $1,350.0 million, 364-day credit facility that are outstanding
upon its termination in February 2004 is extendible by the Company for
an additional year. The credit facilities contain substantially
identical financial and other covenants, representations, warranties,
conditions and default provisions as the maturing facility.

At March 31, 2003, the Company had commercial paper outstanding of
$557.7 million which is supported by the credit facilities identified
above and was classified as long-term debt.


Note 3. Contingencies and Commitments
-----------------------------

The Company is involved in various legal proceedings, including
product liability and environmental matters of a nature considered
normal to its business. It is the Company's policy to accrue for
amounts related to these legal matters if it is probable that a
liability has been incurred and an amount is reasonably estimable.

The nationwide class action settlement to resolve litigation brought
against the Company regarding use of the diet drugs PONDIMIN (which in
combination with phentermine, a product that was not manufactured,
distributed or sold by the Company, was commonly referred to as
"fen-phen") or REDUX received final judicial approval effective
January 3, 2002. In connection with the REDUX and PONDIMIN diet drug
matter, the Company has recorded litigation charges totaling $14,600.0
million. These charges are intended to cover the total amount required
to resolve all diet drug litigation, including anticipated funding
requirements for the nationwide class action settlement, anticipated
costs to resolve the claims of any members of the settlement class who
in the future may exercise an intermediate or back-end opt out right,
costs to resolve the claims of primary pulmonary hypertension (PPH)
claimants and initial opt out claimants, and administrative and
litigation expenses.

During the 2003 first three months, individual settlement payments,
legal fees and other costs totaling $134.6 million were paid and
applied against the litigation accrual. At March 31, 2003, $1,816.1
million of the litigation accrual remained.

In December 2002, following a joint motion by the Company and
plaintiffs' counsel, the Court approved an amendment to the settlement
agreement which provided for the merger of Funds A and B into a
combined fund which will now cover all expenses and injury claims in
connection with the settlement. The effect of the merger is to
accelerate the spillover of the expected remainder in Fund A, which
will now be available to pay


9


WYETH
NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS
(Unaudited)

Fund B claims. The merger of the two funds took place in January 2003.
In February 2003, as required by the amendment to the settlement
agreement merging the two settlement funds, an additional $535.2
million was added by the Company to the security fund. The Company
established the security fund as collateral for the Company's
financial obligations under the settlement. The amounts in the
security fund are owned by the Company and will earn interest income
for the Company while residing in the security fund.

The Company continuously reviews its diet drug litigation reserve as
additional information becomes available with respect to claims both
inside and outside of the nationwide class action settlement. Within
the settlement, the number of individuals who have filed claims that
allege significant heart valve disease (known as matrix claims) has
been higher than had been anticipated. While the Company does not have
precise current information, the settlement trust has recorded in
excess of 61,000 matrix-level claim forms to date and it is likely
that a substantial number of forms have been received but not yet
logged in. Only half of these forms have been processed to date, and
only a very small percentage of that half have been found valid and
been paid. In addition, in light of substantial questions that have
been raised concerning the validity of many of these matrix claims,
the federal court overseeing the nationwide settlement has ordered
that 100% of the matrix claims be audited for eligibility for awards
under the settlement. That 100% audit process is just now beginning
and the Company expects that, as a result of the audit process, only a
fraction of the actual claim forms submitted will result in a payment.

With respect to claims outside of the settlement, the Company has
resolved the claims of all but a small percentage of the "initial" opt
outs (i.e., those individuals who exercised their right to opt out of
the settlement class) and continues to work toward resolving the rest.
In regard to those class members who seek to exercise a "downstream"
opt out right provided by the settlement, based on preliminary
estimates, approximately 70,000 intermediate opt out forms were
submitted by May 3, 2003, the applicable deadline for most class
members (other than qualified class members receiving echocardiograms
through the settlement trust after January 3, 2003, who may exercise
intermediate opt out rights within 120 days after the date of their
echocardiogram). The number of class members who have purported to
exercise a back-end opt out right is estimated to be 20,000 and
certain additional class members will be entitled to exercise back-end
opt out rights in the future. However, the Company expects that the
number of valid opt outs will be substantially less than the number of
forms submitted. First, there is no estimate at this time of the
percentage of those purported exercise forms that are valid, i.e.,
forms that are not duplicative of other filings, that are not filed on
behalf of individuals who have already either received payments from
the settlement trust or settlements from the Company, and are
otherwise not invalid on their face. Second, there is no estimate at
this time of the percentage of the purported opt outs that satisfy the
settlement's medical eligibility requirements. The Company is
vigorously challenging all intermediate and back-end opt out claims of
disputed validity or questionable medical eligibility and the number
of such claims that meet the settlement criteria will not be known for
some time.


10


WYETH
NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS
(Unaudited)

Intermediate and back-end opt outs who meet the settlement's criteria
may pursue lawsuits against the Company, but must prove their cases
without relying on verdicts, judgments or factual findings made in
other lawsuits. They also may not seek or recover punitive, exemplary
or multiple damages and may sue only for the valvular condition giving
rise to their opt out right. The Company plans to vigorously defend
such lawsuits.

Based upon the information currently available, the Company believes
that there is no basis to change its reserves to cover the remaining
obligations relating to the diet drug litigation. However, in light of
the inherent uncertainty in estimating litigation exposure and the
fact that substantial additional information will become available in
the future, it is possible that additional reserves may be required.

In the opinion of the Company, although the outcome of any legal
proceedings cannot be predicted with certainty, the ultimate liability
of the Company in connection with its legal proceedings will not have
a material adverse effect on the Company's financial position but
could be material to the results of operations or cash flows in any
one accounting period.


Note 4. Restructuring Program
---------------------

In December 2002, the Company recorded a special charge for
restructuring and related asset impairments of $340.8 million to
recognize the costs of closing certain manufacturing facilities and
two research facilities, as well as the elimination of certain
positions at the Company's facilities. The Company recorded its asset
impairments in accordance with SFAS No. 144, Accounting for the
Impairment or Disposal of Long-Lived Assets and its restructuring
charges, including personnel and other costs, in accordance with EITF
No. 94-3, Liability Recognition for Certain Employee Termination
Benefits and Other Costs to Exit an Activity (including Certain Costs
Incurred in a Restructuring).

The restructuring will ultimately result in the elimination of
approximately 3,150 positions worldwide. The reductions in workforce
are permanent and affected all of the Company's segments, including
Corporate. As of March 31, 2003, the Company has initiated the process
of closing certain manufacturing facilities and had eliminated
approximately 2,565 positions.

The activity in the restructuring accruals was as follows:

Item 2. Results of Operations
---------------------

Worldwide net revenue for the 2003 first quarter was 1% higher
compared with prior year levels. The increase in worldwide net revenue
for the 2003 first quarter was due primarily to higher worldwide net
revenue of consumer healthcare. Excluding the impact of foreign
exchange, worldwide net revenue decreased 2% for the 2003 first
quarter.

The following table sets forth worldwide net revenue results by
operating segment together with the percentage changes from the

======== ======== ==========


Pharmaceuticals
---------------

Worldwide pharmaceutical net revenue was flat for the 2003 first
quarter. Excluding the impact of foreign exchange, worldwide
pharmaceutical net revenue decreased 3% for the 2003 first quarter.

Worldwide human pharmaceutical net revenue was flat as higher sales of
EFFEXOR XR (substantial global growth), PROTONIX (strong prescription
volume growth) and PREVNAR (reflecting consistent increased
manufacturing capability) were offset by lower sales of the PREMARIN
family of products and CORDARONE I.V. (market exclusivity ended
October 2002). Excluding the impact of foreign exchange, worldwide
human pharmaceutical net revenue decreased 3% for the 2003 first
quarter.

Worldwide animal health product net revenue increased 13% for the 2003
first quarter. The increase in sales of animal health products was due
primarily to higher U.S. sales of the Company's WEST NILE - INNOVATOR
biological vaccine for horses. Excluding the impact of foreign
exchange, worldwide animal health product net revenue increased 11%
for the 2003 first quarter.

Management's Discussion and Analysis of Financial Condition
and Results of Operations
Three Months Ended March 31, 2003

Cost of goods sold, as a percentage of net revenue, increased to 25.2%
for the 2003 first quarter compared with 22.0% for the 2002 first
quarter due primarily to higher manufacturing costs and a less
profitable product mix related to lower sales of higher margin
products. This increase was partially offset as a result of increased
alliance revenue recorded in the 2003 first quarter net revenue as
compared with the 2002 first quarter net revenue. There are no costs
of goods sold relating to alliance revenue, and therefore any net
revenue fluctuations impacted by alliance revenue will also impact
gross margins.

Selling, general and administrative expenses, as a percentage of net
revenue, remained flat for the 2003 first quarter as compared with the
same period in the prior year at approximately 35.0% due primarily to
lower selling and marketing expenditures offset by higher general
expenses associated with increased insurance and pension and other
employee benefit costs.

Research and development expenses increased 7% for the 2003 first
quarter due primarily to higher clinical grant spending, cost sharing
and licensing expenditures from pharmaceutical collaborations offset,
in part, by reduced spending for operating expenses, including lower
chemical and material costs.

Interest expense, net decreased 49% in the 2003 first quarter due
primarily to lower weighted average debt outstanding, as compared with
the 2002 first quarter. Weighted average debt outstanding during the
2003 and 2002 first quarters was $7,152.6 million and $9,932.2
million, respectively. The decrease in interest expense was also
affected by higher capitalized interest resulting from spending for
capital projects.

Other income, net decreased significantly for the 2003 first quarter
due in part to lower gains on sales of non-strategic assets and the
non-recurrence of income received in 2002 in connection with a class
action settlement gain relating to price fixing by certain vitamin
suppliers.

(*) Corporate for the 2003 first quarter included a gain of $860.6
relating to the sale of Amgen shares. Excluding the gain on the
sale of Amgen shares from the 2003 first quarter results,
Corporate expenses, net decreased 8%.


Worldwide pharmaceutical income before taxes decreased 12% for the
2003 first quarter due primarily to lower gross profit margins earned
on worldwide sales of human pharmaceuticals combined with higher
research and development expenses and lower other income, net
(primarily lower gains on sales of non-strategic assets and the
non-recurrence of equity income received in 2002) offset, in part, by
lower selling, general and administrative expenses.

Worldwide consumer healthcare income before taxes decreased 50% for
the 2003 first quarter while consumer healthcare sales increased 8%.
This difference is primarily attributable to the non-recurrence of
income received in 2002 in connection with a class action settlement
gain relating to price fixing by certain vitamin suppliers, lower
asset sale gains, and higher selling, general and administrative
expenses as a percentage of sales primarily due to increased marketing
and selling expenses associated with the launch of ALAVERT.

Corporate expenses, net, decreased 8% for the 2003 first quarter,
excluding the 2003 first quarter gain of $860.6 million from the sale
of the Company's remaining Amgen shares. The decrease in corporate
expenses, net is due primarily to lower interest expense resulting
from lower weighted average debt outstanding as compared with the 2002
first quarter and higher other income, net relating to gains on the
Company's foreign exchange hedging programs. These items were
partially offset by higher general expenses related to increased group
and general insurance expenses.

Excluding the 2003 first quarter gain on the sale of the Company's
remaining Amgen shares, the effective tax rate remained flat at 22.0%
for the 2003 first quarter compared with 22.3% for the 2002 first
quarter.


Consolidated Net Income and Diluted Earnings Per Share Results
--------------------------------------------------------------

Net income and diluted earnings per share for the 2003 first quarter
increased to $1,277.9 million and $0.96 compared with $871.9 million
and $0.65 in the prior year. The 2003 first quarter net income and
diluted earnings per share included a gain of $860.6 million ($558.7
million after-tax or $0.42 per share-diluted) related to the sale of
the remaining 31,235,958 shares of the Company's Amgen common stock
holdings. Excluding the gain on the sale of Amgen shares from the 2003
first quarter results, net income and diluted earnings per share for
the 2003 first quarter decreased 18% and 17%, respectively, to $719.2
million and $0.54 compared with the 2002 first quarter. The decreases
in net income and diluted earnings per share for the 2003 first
quarter were impacted by higher costs of goods sold as a percentage of
net revenue, higher research and development expenses and lower other
income.


Liquidity, Financial Condition and Capital Resources
----------------------------------------------------

Cash flows provided by operating activities totaling $328.4 million
during the 2003 first quarter were generated primarily by earnings of
$1,277.9 million and proceeds of $213.4 million relating to improved
collections on outstanding accounts receivable. Driving the cash
outflows were payments of $134.6 million relating to the diet drug
litigation and a payment of $535.2 million to the security fund as
collateral for the Company's financial obligations under the diet drug
settlement (see Note 3 to the consolidated condensed financial
statements). Additionally, payments made on outstanding payables and
accrued expenses totaling $123.6 million and an increase in
inventories of $160.9 million due primarily to production planning
impacted cash outflows.

The Company generated $1,216.1 million of cash from investing
activities during the 2003 first quarter due primarily to proceeds
received of $1,579.9 million relating to the sale of the Company's
remaining 31,235,958 shares of Amgen common stock. The Company used
$547.9 million for investments in property, plant and equipment and
marketable securities. The capital expenditures made during the 2003
first quarter were consistent with the Company's commitment to expand
existing manufacturing and research and development facilities
worldwide, and build new biotechnology facilities.

The Company also used cash for financing activities relating to
repayments of net debt totaling $1,456.7 million and dividend payments
of $305.1 million.

At March 31, 2003, the Company had outstanding $6,923.2 million in
total debt. The Company's total debt consisted of commercial paper of
$557.7 million, and notes payable


20


Management's Discussion and Analysis of Financial Condition
and Results of Operations
Three Months Ended March 31, 2003

and other debt of $6,365.5 million. The Company offers its commercial
paper in a very liquid market commensurate with its short-term credit
ratings from Moody's (P2), S&P (A1) and Fitch (F1). Current debt at
March 31, 2003, classified as loans payable, consisted of $514.0
million of notes payable and other debt that is due within one year.
All of the commercial paper outstanding at March 31, 2003 was
supported by the Company's new credit facilities, totaling $2,700.0
million, and is classified as long-term debt.

Management remains confident that cash flows from operating activities
and existing and prospective financing resources will be adequate to
fund the Company's operations, pay opt out settlement payments and
fund the nationwide class action settlement relating to the REDUX and
PONDIMIN diet drug litigation, pay dividends, maintain the ongoing
programs of capital expenditures, and repay both the principal and
interest on its outstanding obligations, without requiring the
disposition of any significant strategic core assets or businesses.


Certain Factors that May Affect Future Results
----------------------------------------------

Prempro / Premarin - HRT Studies

Two subsets of the Women's Health Initiative (WHI) enrolled a total of
27,000 predominantly healthy postmenopausal women to assess the risks
and benefits of either long-term estrogen replacement therapy (ERT) or
long-term hormone replacement therapy (HRT). The primary endpoint of
the WHI study was coronary heart disease, with invasive breast cancer
as the primary adverse outcome studied. The HRT subset of the WHI
study, involving women who received a combination of conjugated
estrogens and medroxyprogesterone acetate (PREMPRO), was stopped early
(after the patients were followed in the study for an average of 5.2
years) because, according to the predefined stopping rule, increased
risks of breast cancer and cardiovascular events exceeded the
specified long-term benefits. The study observed an increased
incidence of cardiovascular disease and, over time, breast cancer
among women on HRT compared to those on placebo. The study also
observed a reduction in the incidence of hip, vertebral and other
osteoporotic fractures and of colon cancer among women on HRT compared
to those on placebo. The study did not evaluate the use of HRT for the
treatment of menopausal symptoms, the main indications of the product.
These findings provide additional information about the risks of
breast cancer and cardiovascular disease which were identified as
potential adverse events in the labeling for the Company's HRT
products. Additional analyses of data from the HRT subset of the WHI
study are expected to be released over the next several months.

Sales of PREMPRO and other PREMARIN family products have been and will
continue to be adversely affected by the WHI results. Based on the
most recent available market data, average weekly prescriptions
written for PREMPRO and PREMARIN decreased approximately 67% and 33%,
respectively, compared to the average weekly


21

prescriptions written during the eight-week period preceding the
termination of the study subset. PREMPRO sales (including PREMPHASE)
for the three months ended March 31, 2003 represented approximately 4%
of consolidated net revenue. Set forth below are individual product
operating results for both PREMPRO/PREMPHASE and PREMARIN for the

Competition

The Company operates in the highly competitive pharmaceutical and
consumer health care industries. PREMARIN, the Company's principal
conjugated estrogens product manufactured from pregnant mare's urine,
and related products PREMPRO and PREMPHASE (which are single tablet
combinations of the conjugated estrogens in PREMARIN and the progestin
medroxyprogesterone acetate), are the leaders in their categories and
contribute significantly to the Company's net revenue and results of
operations. PREMARIN's natural composition is not subject to patent
protection (although PREMPRO has patent protection). The principal
indications of PREMARIN, PREMPRO and PREMPHASE are to manage the
symptoms of menopause and to prevent osteoporosis, a condition
involving a loss of bone mass in postmenopausal women.
Estrogen-containing products manufactured by other companies have been
marketed for many years for the treatment of menopausal symptoms.
During the past several years, other manufacturers have introduced
products for the treatment and/or prevention of osteoporosis. New
products containing different estrogens and/or different progestins
than those found in PREMPRO and PREMPHASE, utilizing various forms of
delivery and having one or more of the same indications have also been
introduced. Some companies have attempted to obtain approval for
generic versions of PREMARIN. These products, if approved, would be
routinely substitutable for PREMARIN and related products under many
state laws and third-party insurance payer plans. In May 1997, the FDA
announced that it would not approve certain synthetic estrogen
products


22


Management's Discussion and Analysis of Financial Condition
and Results of Operations
Three Months Ended March 31, 2003

as generic equivalents of PREMARIN given known compositional
differences between the active ingredient of these products and
PREMARIN. Although the FDA has not approved any generic equivalent to
PREMARIN to date, PREMARIN will continue to be subject to competition
from existing and new competing estrogen and other products for its
approved indications and may be subject to generic competition from
either synthetic or natural conjugated estrogens products in the
future. At least one other company has announced that it is in the
process of developing a generic version of PREMARIN from the same
natural source, and the Company currently cannot predict the timing or
outcome of these or any other efforts.


Product Supply

Market demand for ENBREL is strong; however the sales growth had been
constrained by limits on the existing source of supply. In December
2002, the retrofitted Rhode Island facility owned by Amgen was
completed, and manufacturing production was approved by the FDA.
Consequently, manufacturing capacity for ENBREL will significantly
increase in 2003. Market demand is expected to continue to grow, and
additional manufacturing supply is projected to be required. In April
2002, Immunex (prior to being acquired by Amgen) announced it entered
into a manufacturing agreement with Genentech, Inc. to produce ENBREL
beginning in 2004, subject to FDA approval. The current plan for the
longer term includes an additional manufacturing facility, which is
being constructed by the Company in Ireland and expansion of the Rhode
Island facility, both of which are expected to be completed during
2005.


Litigation and Contingent Liabilities

The Company is involved in various legal proceedings, including
product liability and environmental matters that arise from time to
time in the ordinary course of business, the most significant of which
are described in the Company's Annual Report on Form 10-K for the year
ended December 31, 2002 and this Quarterly Report on Form 10-Q. These
include allegations of injuries caused by drugs, vaccines and
over-the-counter products, including PONDIMIN (which in combination
with phentermine, a product that was not manufactured, distributed or
sold by the Company, was commonly referred to as "fen-phen"), REDUX,
DIMETAPP, ROBITUSSIN and PREMPRO. In addition, the Company has
responsibility for environmental, safety and cleanup obligations under
various local, state and federal laws, including the Comprehensive
Environmental Response, Compensation and Liability Act, commonly known
as Superfund.

The estimated costs that the Company expects to pay in these cases are
accrued when the liability is considered probable and the amount can
be reasonably estimated. In many cases, future environmental-related
expenditures cannot be quantified with a reasonable degree of
accuracy. As investigations and cleanups proceed,
environmental-related liabilities are reviewed and adjusted as
additional information becomes available. In


23


Management's Discussion and Analysis of Financial Condition
and Results of Operations
Three Months Ended March 31, 2003

addition, the Company is self-insured against ordinary product
liability risks and has liability coverage, in excess of certain
limits and subject to certain policy ceilings, from various insurance
carriers. It is the opinion of the Company that any potential
liability that might exceed amounts already accrued will not have a
material adverse effect on the Company's financial position but could
be material to the results of operations or cash flows in any one
accounting period.

Management's Discussion and Analysis of Financial Condition
and Results of Operations
Three Months Ended March 31, 2003

whether as a result of new information, future developments or
otherwise. Certain factors which could cause the Company's actual
results to differ materially from expected and historical results are
discussed herein and others have been identified by the Company in
Exhibit 99 to the Company's 2002 Annual Report on Form 10-K, which
exhibit is incorporated herein by reference.

Item 3. Quantitative and Qualitative Disclosures About Market Risk
----------------------------------------------------------

The market risk disclosures appearing on page 65 of the Company's 2002
Annual Report as incorporated by reference on Form 10-K have not
materially changed from December 31, 2002.

At March 31, 2003, the fair values of the Company's financial
instruments were as follows:

Carrying Fair
Notional/ Value Value
(In millions) Contract ----------------------
Description Amount Assets (Liabilities)
--------------------- ------------------------------------
Forward contracts (1) $826.3 $8.8 $8.8
Option contracts (1) 883.0 (22.1) (22.1)
Interest rate swaps 3,300.0 216.7 216.7
Outstanding debt (2) 6,721.9 (6,923.2) (7,194.7)


(1) If the value of the U.S. dollar were to increase or decrease by
10%, in relation to all hedged foreign currencies, the net
payable on the forward and option contracts would decrease or
increase by approximately $70.3.

(2) If the interest rates were to increase or decrease by one
percentage point, the fair value of the outstanding debt would
increase or decrease by approximately $325.1.

The estimated fair values approximate amounts at which these financial
instruments could be exchanged in a current transaction between
willing parties. Therefore, fair values are based on estimates using
present value and other valuation techniques that are significantly
affected by the assumptions used concerning the amount and timing of
estimated future cash flows and discount rates that reflect varying
degrees of risk. Specifically, the fair value of outstanding debt
instruments reflects a current yield valuation based on observed
market prices as of March 31, 2003; the fair value of interest rate
swaps and forward contracts reflects the present value of the future
potential gain or (loss) if settlement were to take place on March 31,
2003; and the fair value of option contracts reflects the present
value of future cash flows if the contracts were settled on March 31,
2003.


Item 4. Controls and Procedures
-----------------------

Within the 90 days prior to the date of filing this Quarterly Report
on Form 10-Q, the Company carried out an evaluation, under the
supervision and with the participation of the Company's management,
including the Chief Executive Officer and Chief Financial Officer, of
the effectiveness of the design and operation of the Company's
disclosure controls and procedures pursuant to Exchange Act Rule
13a-14. Based upon that evaluation, the Chief Executive Officer and
Chief Financial Officer concluded that the Company's disclosure
controls and procedures are reasonably effective in design and
practice to alert them, in a timely manner, to material information
relating to the Company (including its consolidated subsidiaries)
required to be included in the


26


Company's periodic SEC filings. Subsequent to the date of that
evaluation, there have been no significant changes in the Company's
internal controls or in other factors that could significantly affect
internal controls, nor were any corrective actions required with
regard to significant deficiencies or material weaknesses.


27


Part II - Other Information
---------------------------

Item 1. Legal Proceedings
-----------------

The Company and its subsidiaries are parties to numerous lawsuits and
claims arising out of the conduct of its business, including product
liability and other tort claims, the most significant of which are
described in the Company's Annual Report on Form 10-K for the year
ended December 31, 2002.

In the litigation involving PREMPRO, the Company's estrogen and
progestin replacement therapy, three additional putative class action
lawsuits have been filed. Brown, et al. v. Wyeth, No. CV03-0138S,
U.S.D.C., W.D. La; Slater, et al. v. Wyeth, No. 03-4016-CV-C-NKL,
U.S.D.C., W.D. Mo; and Phillips, et al. v. Wyeth, No. CV03-5, Cir.
Ct., Jefferson Cty., AL. Slater seeks to represent a nationwide class
of women who have ever ingested PREMPRO and seeks on behalf of the
putative class: 1) purchase price refunds; 2) personal injury damages;
3) medical monitoring expenses and 4) an order requiring the Company
to inform the public of the reported risks of PREMPRO. Brown and
Phillips seek similar relief on behalf of putative classes of
Louisiana and Alabama users of the product, respectively. In addition
to the 16 class actions, the Company is defending approximately 40
individual actions and 13 multi-plaintiff actions (with a total of
approximately 130 named plaintiffs) in various courts for personal
injuries including breast cancer, stroke and heart disease.

The Company intends to continue to defend all of the foregoing
litigation vigorously.

In the litigation involving allegations that the Company violated
federal and state antitrust laws through alleged exclusionary
practices regarding PREMARIN and the Company's contracts with managed
care organizations and pharmacy benefit managers, United States
District Judge Sandra S. Beckwith has granted the direct-purchasers'
motion for class certification. J.B.D.L. Corp. d/b/a/ Beckett
Apothecary, et al. v. Wyeth-Ayerst Laboratories, Inc., et al., No.
C-1-01-704, U.S.D.C., S.D. Oh. Three putative indirect-purchaser class
actions with allegations similar to those contained in the J.B.D.L.
complaint are presently pending against the Company. One putative
indirect-purchaser class action is pending in Ohio federal district
court, and two putative indirect-purchaser class actions are pending
in California state courts. The complaints seek injunctive relief,
damages, and disgorgement of profits. The Company believes that its
contracts involving PREMARIN do not violate state or federal laws.

On April 11, 2003, the U.K. Competition Commission report on its
investigation into the supply of prescription-only veterinary
medicines in the U.K. concluded that three monopoly situations exist
in the U.K. market for such medicines. According to the report, one
such monopoly situation arises from the failure of eight animal-health
manufacturers, including Fort Dodge Animal Health U.K., to enable
pharmacies to obtain supplies of prescription-only veterinary
medicines on terms that would enable them to compete with veterinary
surgeons. The report recommended two remedies for the situation,
applicable to all of the relevant manufacturers, which are designed to
allow the pharmacies to obtain prescription-only veterinary medicines
on competitive terms with the veterinary surgeons. The U.K. Office of
Fair Trading will consult with the relevant


28


parties on the terms of orders to implement the Commission's remedies
during the next three months.

In the opinion of the Company, although the outcome of any legal
proceedings cannot be predicted with certainty, the ultimate liability
of the Company in connection with its legal proceedings will not have
a material adverse effect on the Company's financial position but
could be material to the results of operations in any one accounting
period.
