Supplemental schedule of noncash investing and financing activities:

During January 2002, the Company acquired 100% of the outstanding capital stock of Aviron through an exchange offer and merger
transaction. The Company exchanged approximately 34.0 million of its common shares for all of the outstanding shares of Aviron
common stock and assumed Aviron's outstanding options and warrants, for which approximately 7.0 million additional shares of the
Company's common stock are issuable. The estimated fair value of the net assets acquired was $1,636.4 million, including $1,179.3
million of acquired research and development assets that were charged to current period results at the date of acquisition.

General

The financial information presented as of March 31, 2002 is unaudited. In the opinion of the Company's management, the financial
information presented herein contains all adjustments (which consist only of normal recurring adjustments) necessary for a fair
presentation of results for the interim periods presented. Interim results are not necessarily indicative of results for an entire
year or for any subsequent interim period. These consolidated financial statements should be read in conjunction with the Company's
annual report on Form 10-K for the year ended December 31, 2001.

Organization

MedImmune, Inc., a Delaware corporation (together with its subsidiaries, the "Company"), is a biotechnology company headquartered
in Gaithersburg, Maryland.  The Company currently has five products on the market and maintains a diverse product portfolio.  The
Company is focused on using advances in immunology and other biological sciences to develop important new products that address
significant medical needs in areas such as infectious diseases, immune regulation and oncology.

During January 2002, the Company completed its acquisition of Aviron, a biopharmaceutical company headquartered in Mountain View,
California, through an exchange offer and merger transaction.  The acquisition was accounted for as a purchase, and the results
of operations of Aviron are included in the results of the Company effective January 10, 2002.

New Accounting Standard

Effective January 1, 2002, the Company adopted SFAS No. 142 ("SFAS 142"), "Goodwill and Other Intangible Assets".  SFAS 142
addresses financial accounting and reporting for acquired goodwill and other intangible assets and supersedes APB Opinion No. 17,
"Intangible Assets."  Under SFAS 142, goodwill and intangible assets with indefinite lives are no longer amortized but are
reviewed at least annually for impairment.  The amortization provisions of SFAS 142 apply to goodwill and intangible assets
acquired after June 30, 2001.  The adoption of  SFAS 142 did not have an impact on the Company's financial position, results of
operations, or cash flows.

Change in Accounting Method

For new contracts executed after January 1, 2002, the Company has changed its accounting method for contract revenues such that the
Company may recognize contract revenues associated with substantive at risk performance milestones when the milestone is achieved,
when no future service obligation is attendant to that milestone, and when the related revenue is due and payable under the
milestone payment method. The change in accounting principle was made to more closely reflect the essence of the contractual
obligations the Company enters into with collaborative partners. Specifically, milestone payments are often directly related to the
completed portion (an achieved milestone) of the arrangement and are therefore earned as the milestone is achieved. Also, the new
method is prevalent in the industry in which the Company operates. The effect on earnings and earnings per share for the three
months ended March 31, 2002 is not material. In circumstances where it is not appropriate to use the milestone payment method, the
Company will continue to use the contingency-adjusted performance model.

Significant Accounting Policies

Contract Revenues - For contracts executed prior to January 1, 2002, contract revenues are recognized over the fixed term of the
contract as the related expenses are incurred.  Upfront fees and milestone payments under collaborative agreements are recognized
when they are earned in accordance with the applicable performance requirements and contractual terms, using the
contingency-adjusted performance model for revenue recognition.  Under this method, payments received that are related to future
performance are deferred and recorded as revenues as they are earned over specified future performance periods.  The amount of
revenue recognized during each period is based on a percentage-of-completion model based on actual costs incurred relative to the
total projected costs.  Recognized revenues are subject to revisions as the collaboration efforts progress and estimated costs to
complete are revised.  For new contracts executed after January 1, 2002, contract revenues associated with substantive at-risk
performance milestones may be recognized when the milestone is achieved and the related revenue is due and payable under the
milestone payment method.  Under this method, milestone revenues may be recognized when the milestone is achieved, when no future
service obligation is attendant to that milestone, and when the related revenue is due and payable.  The milestone payment method
may not be applicable to all new contracts, in which case the Company would revert to the contigency-adjusted performance model
for revenue recognition.

Acquisition

On January 10, 2002, the Company completed its acquisition of Aviron through an exchange offer and merger transaction pursuant to
the definitive merger agreement between the two parties dated December 2, 2001.  Aviron is a biopharmaceutical company
headquartered in Mountain View, California, focused on prevention of disease through innovative vaccine technologies.  Aviron's
lead product candidate is FluMist, a live, attenuated virus vaccine delivered as a nasal mist for the prevention of influenza.
FluMist has not been approved by the FDA.

Under the terms of the agreement, the Company exchanged approximately 34.0 million of its common shares for 100% of the
outstanding common stock of Aviron.  Additionally, approximately 7.0 million shares are issuable upon the exercise of Aviron's
outstanding options and warrants.  Holders of Aviron's $200 million of 5 1/4% convertible subordinated notes due in 2008 may convert
the notes into a total of approximately 3.4 million shares of the Company's common stock.

The acquisition was accounted for as a purchase and, accordingly, the results of Aviron's operations have been included with the
Company's since the acquisition date.


The aggregate purchase consideration was approximately $1.6 billion, as follows (in thousands):

The value of common shares issued was $44.10 per share, based on the closing market price of the Company's common stock on
November 30, 2001, the last business day prior to the signing of the merger agreement.  The fair value of Aviron's options and
warrants assumed in the transaction was estimated using the Black-Scholes option pricing model.

The following table summarizes the estimated fair values (in thousands) of the assets acquired and liabilities assumed at the
date of acquisition.  The Company is in the process of determining the fair value of certain tangible assets and liabilities;
thus, the allocation of the purchase price is subject to refinement:

Of the $129.0 million of acquired intangible assets, $90.0 million was assigned to Aviron's worldwide collaborative agreement
with Wyeth for the development, manufacturing, distribution, marketing, promotion, and sale of FluMist, which is subject to
amortization over its estimated useful life of approximately 11 years.  The remaining $39.0 million was assigned to Aviron's
contract manufacturing agreement with Evans Vaccines Limited, which is subject to amortization over its estimated useful life of
approximately 4 years.

Approximately $1,179.3 million of the purchase price was allocated to acquired research and development assets that were written
off at the date of acquisition as a separate component of the Company's results  of operations in accordance with FASB
Interpretation No. 4, "Applicability of FASB Statement No. 2 to Business Combinations Accounted for by the Purchase Method."  The
amount represents the fair value of purchased in-process technology for projects that, as of the date of the acquisition, had not
yet reached technological feasibility and had no alternative future use, primarily Aviron's lead product candidate, FluMist,
which has not been approved by the FDA.

Approximately $15.7 million in goodwill was recognized in the transaction, none of which is expected to be deductible for tax
purposes.  In accordance with SFAS 142, the goodwill recognized in the transaction is not amortized, but will be reviewed for
impairment on an annual basis.

Included in the allocation of acquisition cost is a restructuring liability of $16.0 million for estimated costs associated with the
Company's restructuring plan, which was formulated and announced to employees in December 2001, to consolidate and restructure
certain functions, including the involuntary termination of eight Aviron executives and 52 other Aviron employees from various
functions and levels. The restructuring liability primarily consisted of $5.4 million for contractual severance payments, $9.5
million for accelerated vesting of stock options to employees and executives, as dictated by their employment agreements and the
provisions of the various stock options plans, and approximately $1.1 million for estimated costs for vacant lease space which is
not expected to be used by the Company during the remaining term of the lease as a result of the Company's plan to consolidate
certain functions. Subsequent adjustments to the allocation of the acquisition cost related to the true-up of severance and other
restructuring costs are not expected to be significant. During the period from January 10, 2002 through March 31, 2002, there were
no subsequent adjustments to the restructuring liability, and actual severance payments of $4.7 million and compensation expense of
$8.9 million for the accelerated vesting of stock options for terminated executives and employees were charged against the
restructuring liability. As of March 31, 2002, the balance of the restructuring liability was $2.4 million.

Included in the allocation of acquisition cost are accrued transaction costs of $9.8 million, which primarily consist of
investment banking, accounting and legal fees incurred by the Company.  As of March 31, 2001, the balance of accrued transaction
costs was $1.7 million.

The following unaudited pro forma condensed combined supplemental data present the revenues, net earnings and earnings per share of
the combined entity as though the business combination had been completed as of January 1, 2002 and 2001, respectively. The
unaudited pro forma condensed combined supplemental data gives effect to actual operating results prior to the acquisition, adjusted
to include the pro forma effect of amortization of intangibles, deferred stock compensation costs, the elimination of the
non-recurring charge for acquired in-process research and development, the tax effects to the pro forma adjustments and the
recognition of the tax benefits arising from Aviron's net loss for the 2001 period. The unaudited pro forma condensed combined
supplemental data are not necessarily an indication of the results that would have been achieved had the transaction been
consummated as of the dates indicated or that may be achieved in the future.

(1)        Excludes a non-recurring charge of $1,179.3 million for acquired in-process research and development.


Long-term Debt

Following the Company's acquisition of Aviron, Aviron remains obligated for its outstanding indebtedness, which included $200.0
million aggregate principal amount of 5 1/4% Convertible Subordinated Notes (the "Notes") due 2008.  Approximately $211.4 million of
the acquisition cost was allocated to the Notes, which represents the fair value as of the acquisition date, based on quoted
market prices.  The Notes are convertible into an aggregate of 3.4 million shares of the Company's common stock, based on a
conversion price of $58.14, at any time on or before January 15, 2008.  Aviron may redeem the Notes beginning in January 2004, at
redemption prices declining from 103% of their principal amount in 2004 to 100% in 2008, plus accrued interest.  Interest is
payable semi-annually in arrears in cash on January 15 and July 15 each year.

Derivative Instruments and Hedging Activities

The Company adopted SFAS 133, "Accounting for Derivative Instruments and Hedging Activities", on January 1, 2001.

The Company purchases inventory from a foreign vendor and pays the vendor in a foreign currency.  This exposes the Company to
foreign currency exchange rate risk, which is monitored by the Company as part of its overall risk-management program.  The
Company uses foreign-currency forward-exchange contracts to hedge these risks.  SFAS 133 requires that all derivatives be
recorded on the balance sheet at fair value.  Changes in the value of foreign-currency forward-exchange contracts are recorded in
other comprehensive income and recognized in earnings when the hedged forecasted transaction occurs.

The Company accounts for its derivatives as foreign-currency cash-flow hedges and is required to recognize any ineffectiveness on
hedging transactions as interest income or expense in the statement of operations. For the quarter ended March 31, 2002, gains or
losses for ineffective hedges were insignificant. As of March 31, 2002, deferred losses on derivative instruments accumulated in
other comprehensive income are immaterial and are expected to be reclassified to earnings in the next 12 months in conjunction with
the sale of the related inventory. The maximum term over which the Company is hedging its exposures to the variability of cash flows
is 12 months.


Inventory

Inventory, net of reserves, is comprised of the following (in thousands):

Noncurrent inventory at March 31, 2002 and December 31, 2001 is comprised of some of the Company's raw plasma and certain CytoGam
production lots that are being tested for long-term stability which are not expected to be available for sale within the next 12
months.

Inventory balances are net of reserves for RespiGam inventory, for which minimal product sales are expected to result for the
foreseeable future.  RespiGam inventory and reserve balances were $4.8 million and $4.0 million, respectively, at March 31, 2002,
versus $4.9 million and $4.2 million, respectively, at December 31, 2001.

Earnings per Share

The Company computes earnings per share in accordance with Statement of Financial Accounting Standards No. 128, "Earnings Per
Share."  Basic earnings per share is computed based on the weighted average number of common shares outstanding during the
period. Diluted earnings per share is computed based on the weighted average shares outstanding adjusted for all dilutive
potential common shares.  The dilutive impact, if any, of common stock equivalents outstanding during the period, including
outstanding stock options and warrants, is measured by the treasury stock method.  The dilutive impact, if any, of the Notes is
measured using the if-converted method.  Common stock equivalents are not included in periods where there is a loss as they are
anti-dilutive.  The following is a reconciliation of the denominator of the diluted EPS computation for the periods reported.
There are no reconciling items to the numerator for the EPS computation for the periods reported.

                                                                             Three Months                  Three  Months

The Company incurred a net loss for the first quarter of 2002 and, accordingly, did not assume exercise or conversion of any of
the Company's outstanding stock options, warrants, or Notes because to do so would be anti-dilutive.  Options to purchase
6,710,375 shares of common stock with prices ranging from $45.00 to $83.25 per share that were outstanding in the first quarter
of 2001 were not included in the computation of diluted earnings per share because they were anti-dilutive.

Income Taxes

Income tax expense for the three months ended March 31, 2002 was $34.9 million.  Excluding the Company's write-off of purchased
in-process research and development, which is not tax deductible, income tax expense as a percentage of pre-tax income for the
three months ended March 31, 2002 was 35.9%.  During the quarter ended March 31, 2002, the Company recognized credits for
research and development expenditures and credits earned for Orphan Drug status of certain research and development expenses,
resulting in a reduction from the statutory rate of 37.0%.

Comprehensive (Loss) Income

Comprehensive (loss) income is comprised of net (loss) earnings and other comprehensive (loss) income. Other comprehensive (loss)
income includes certain changes in equity that are excluded from net (loss) earnings, such as translation adjustments, unrealized
holding gains and losses on available-for-sale marketable securities, and gains and losses on hedging instruments.

Comprehensive (loss) income for the three months ended March 31, 2002 was $(1,126.1) million versus $74.8 million for the comparable
period in 2001. A significant component of other comprehensive loss for the three months ended March 31, 2002 relates to unrealized
holding losses on available-for-sale marketable securities of approximately $9.1 million, net of tax, versus unrealized holding
losses of $3.4 million, net of tax, for the three months ended March 31, 2001. In connection with its research and development
collaborations, the Company holds minority interests in companies having operations or technology in areas within its strategic
focus, some of which are publicly traded and have highly volatile share prices.

Property and Equipment

During March 2002, the Company paid approximately $13.4 million to acquire 25 acres of land in Gaithersburg, Maryland, which will
serve as the site of the Company's new corporate headquarters. The Company has contracted with a designer and general contractor for
the construction of the new facility over the next several years, at a total estimated cost of $85 million. Construction began
during March 2002. The Company expects to take occupancy of the first phase, which will feature a complex totaling 218,000 square
feet, in the fall of 2003.

Collaborative Arrangements

Wyeth
In January 1999, Aviron signed a worldwide collaborative agreement with Wyeth Lederle Vaccines, a subsidiary of Wyeth, for the
development, manufacturing, distribution, marketing, promotion, and sale of FluMist.  Under this agreement, Wyeth has exclusive
worldwide rights to market FluMist, excluding Korea, Australia, New Zealand and some South Pacific countries.  The two companies
will co-promote FluMist in the U.S.  Wyeth holds the marketing rights for an initial term of seven years from the first
commercial sale of FluMist in the U.S. and an initial term of eight years from the first commercial sale of FluMist outside the
U.S. Wyeth has the option to extend its rights both in the U.S. and internationally for an additional four years, which could
result in payments to the Company in excess of $140 million.

Under the terms of the agreement with Wyeth, the two companies are to collaborate on the regulatory, clinical and marketing programs
for FluMist. As a part of the collaboration, the Company is to receive certain payments related to the achievement of key milestones
and events for FluMist. In January 2001, Aviron received $15.5 million from Wyeth related to the acceptance by the FDA for the
filing of the BLA for FluMist on December 28, 2000. Potential milestone payments to the Company from Wyeth include: $20 million for
approval in the U.S.; $20 million for advisory body recommendations and expanded label claims; up to $17.5 million for FDA approval
of use in second and third target populations; $10 million for the submission of a license application in Europe; a $27.5 million
payment for the approval of a liquid formulation of FluMist, and up to $50 million upon licensure in international regions.
Compensation for achieving additional development, supply and regulatory milestones is also included in the collaboration agreement
and may total up to an additional $67.5 million. The total potential value for the license fees, milestones, financing support and
term extension options that the Company could receive from Wyeth could exceed $400 million.

Under the terms of the agreement, Wyeth will distribute FluMist and record all product sales. The Company will receive approximately
50% of FluMist revenues, paid in the form of product transfer payments and royalties. These payments are higher in the U.S. than
internationally. The Company incurs expenses to manufacture, supply and co-promote FluMist. Wyeth reimburses the Company for a
portion of the product's clinical development expenses and has agreed to spend up to $100 million for sales and marketing of FluMist
over the first three years of commercialization in the United States.

Evans Vaccines Limited
In July 1999, Aviron entered into an agreement with a division of Celltech Group Plc, which was later acquired by PowderJect
Pharmaceuticals Plc and is now called Evans Vaccines Limited ("Evans"), for the manufacture of key components of FluMist,
specifically the bulk manufacture of monovalents and diluent, as well as use of the manufacturing facilities.  During October
2000, Aviron restructured its agreement with Evans in order to gain direct control over FluMist manufacturing operations. Aviron
obtained responsibility for bulk manufacture of FluMist in Evans' Speke, U.K. facility, hired approximately 100 Evans employees
who had been working on FluMist, and entered into subleases through June 2006 for the FluMist manufacturing areas on the existing
site. In connection with the restructuring of the manufacturing agreement, Aviron made an initial payment of $15.0 million and
the Company is obligated to make four additional annual payments of $3.9 million through the term of the agreement, and other
additional payments totaling $19.0 million, which will be paid over the term of the agreement based on net sales of FluMist, if
and when approved for marketing.  Evans also received warrants for which 67,899 shares of the Company's common stock are issuable
at an exercise price of $44.19 per share. In addition, the Company is obligated to make payments during the term of the agreement
of $225,000 per year for the use of the Aviron unit in the Evans manufacturing plant, payments up to an aggregate of $3.0 million
for attaining specific milestones, and payments for other support services based on the costs of these services incurred. The
Company expenses rent and other support services as the costs are incurred and expenses milestones as they become due.

Legal Proceedings

In 1998, MediGene AG ("MediGene") initiated a legal action against Loyola University of Chicago ("Loyola") and the Company in the
U.S. District Court for the Northern District of Illinois alleging, among other things, breach of contract and tortious
interference by the Company with an alleged prospective business relationship between MediGene and Loyola. The claims relate to
human papillomavirus vaccine technology allegedly covered by contracts between MediGene and the Company and by a license
agreement from Loyola to the Company, under which the Company granted a sublicense to GlaxoSmithKline.  MediGene seeks damages
from the Company ranging from $31.3 million to $86.9 million based on the tortious interference claim, and/or damages ranging
from $10.2 million to $31.3 million based on the breach of contract claim.  MediGene also seeks ownership of the patents in
question, as well as recission of the Company's license agreement from Loyola or rights as a third-party beneficiary thereof.  On
December 22, 2000 and March 15, 2001, the District Court granted summary judgment motions in favor of the Company on all claims.
The District Court ordered entry of final judgment in favor of the Company on March 19, 2002.  On March 27, 2002 MediGene filed a
notice of appeal to the United States Court of Appeals for the Federal Circuit.

In October 2000, Celltech Chiroscience Limited ("Celltech") commenced a legal proceeding against the Company in the U.K. High
Court of Justice, Chancery Division, Patents Court.  Celltech alleges that the Company failed to pay royalties with respect to
its sales of Synagis as required by a license agreement dated January 19, 1998.  Under the agreement, the Company obtained from
Celltech a worldwide license to make, use and/or sell product under a patent (and related applications) pertaining to humanized
antibodies.  In the proceeding, Celltech seeks payment of a 2% royalty based on net sales of Synagis sold or manufactured in the
United States, with interest, and certain costs, including attorney's fees.  The Company has filed answering papers denying that
any royalties are due on the basis that Celltech's U.S. patent does not cover Synagis and has sought dismissal of the case on the
grounds that the legal doctrine of prosecution history estoppel prevents Celltech from claiming that its patent covers Synagis.
On July 20, 2001, the High Court of Justice ordered a hearing, which is expected to take place in late 2002 or early 2003, on
whether it will dismiss Celltech's case on this basis.  On November 29, 2001, the Company received a letter from counsel for
Celltech enclosing a copy of a patent granted by the European Patent Office on November 14, 2001.  That letter requested various
information concerning the manufacture and sale of Synagis in Europe and sought confirmation that the Company would pay royalties
on such sales pursuant to the license agreement dated January 19, 1998.  As of March 25, 2002, the Company had not made the
royalty payments that were the subject of Celltech's letter, and Celltech had not initiated any legal proceeding against the
Company based on its European patent.

On December 18, 2001, Genentech, Inc. ("Genentech") announced that it had been granted a patent relating to certain methods and
compositions used to produce antibodies by recombinant DNA technology.  In June 1997, in anticipation of any potential impact
the issuance of Genentech's patent could have on the production of Synagis, the Company obtained a license to this patent.  The
Company has received from Genentech a letter, dated January 7, 2002, stating that Genentech expects to receive from the Company
royalty payments pursuant to such license. The Company is in the process of evaluating whether any valid claim of Genentech's
patent, as recently issued, covers production of Synagis.  If so, the Company would pay royalties to Genentech on U.S. net sales
of Synagis commencing December 18, 2001. Pending resolution of this issue, the Company has made certain royalty payments to
Genentech under protest and with reservation of all of its rights.  The Company is also evaluating whether any of its other
antibody-based product candidates, if and when approved for marketing by the U.S. Food and Drug Administration, could require a
license under the Genentech patent.

On February 28, 1996, Ichthyol Gesellschaft Cordes, Hermanni & Co. ("Ichthyol Gesellschaft") filed a complaint for refrain,
information and damages with the Regional Court of Hamburg against MedImmune Oncology on the grounds of trademark infringement in
respect of the use of the trademark "Ethyol" in Germany.  No monetary amount is currently being sought in the litigation by
Ichthyol.  Ichthyol is seeking injunctive relief against the use of the trademark Ethyol in Germany.  The suit was dismissed on
January 29, 1997 by the Regional Court of Hamburg.  Ichthyol Gesellschaft filed an appeal and a  judgment was rendered in favor
of MedImmune Oncology in the appellate proceedings.  In January 1999, Ichthyol Gesellschaft filed an appeal on points of law with
the Federal Court of Justice, and in June 1999, Ichthyol Gesellschaft filed the grounds for the appeal on points of law.  By
judgment of May 3, 2001, the Federal Court of Justice reversed the judgment of the Higher Regional Court and remitted the case to
that court for another hearing.  By order of December l9, 2001, the Higher Regional Court ordered Ichthyol to make further
submissions concerning the relevant facts and legal questions.  Ichthyol recently filed its submissions.  Another hearing will
probably be held this summer.

After consultation with its counsel, the Company believes that it has meritorious defenses to the claims referred to above and is
determined to defend its position vigorously.  While it is impossible to predict with certainty the eventual outcome of these
proceedings, the Company believes they are unlikely to have a material adverse effect on its financial position but might have a
material adverse effect on its results of operations for a particular period.




ITEM 2.

                                              MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                                           FINANCIAL CONDITION AND RESULTS OF OPERATIONS


GENERAL

On January 9, 2002, we acquired Aviron, a biopharmaceutical company focused on prevention of disease through innovative vaccine
technologies. We accounted for the acquisition under the purchase method of accounting and have included Avirons operating
results in our consolidated operating results beginning on January 10, 2002.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

For a more detailed discussion of our critical accounting policies and estimates, please refer to Part II, Item 7, "Management's
Discussion and Analysis of Financial Condition Results of Operations" in our 2001 Annual Report on Form 10-K.

Contract Revenues - For contracts executed prior to January 1, 2002, we recognize revenue from upfront and milestone payments
under collaborative agreements using the contingency-adjusted performance model for revenue recognition.  Under this method,
payments received that are related to future performance are deferred and recorded as revenues as they are earned over specified
future performance periods.  The amount of revenue recognized during each period is based on a percentage-of-completion model of
actual costs incurred relative to the total projected costs to be incurred under the collaborative agreement.  When the
performance criteria for a non-refundable milestone payment are met, the cost of the effort that has been incurred to date is
divided by the total projected costs under the development arrangement (i.e., ratio of performance), and revenue is recognized
for that milestone to the extent of the ratio of performance to date.  We followed this method since reasonably dependable
estimates of the revenue and costs applicable to various stages of a collaboration agreement could be made. Recognized revenues
are subject to revisions as the collaboration efforts progress and estimated costs to complete are revised. Revisions in revenue
estimates are recorded to income in the period in which the facts that give rise to the revision become known.

For new contracts executed after January 1, 2002, we have adopted the milestone payment method to account for contract revenues
associated with substantive at-risk performance milestones.  Under this method, milestone revenues may be recognized when the
milestone is achieved, when no future service obligation is attendant to that milestone, and when the related revenue is due and
payable.  This constitutes a change in accounting principle and was made to more closely reflect the essence of the contractual
obligations the Company enters into with collaborative partners.  Specifically, milestone payments are often times directly
related to the completed portion (an achieved milestone) of the arrangement and are therefore earned as the milestone is
achieved.  Additionally, the new method is prevalent in our industry and is used by most other companies in our peer group.  The
effect on earnings and earnings per share for the three months ended March 31, 2002 is not material.  The milestone payment
method may not be applicable to all new contracts, in which case, the Company would revert to the contingency-adjusted
performance model for revenue recognition.



RESULTS OF OPERATIONS
THREE MONTHS ENDED MARCH 31, 2002 AND 2001

Product Sales -


          Product Sales (In  Millions)                      2002            2001
          ----------------------------                     ------          ------

          Synagis                                          $293.0          $221.5

          Ethyol                                            $18.2            $3.3

          CytoGam                                            $7.2            $8.0

          Other Products                                     $2.3            $2.4

          TOTAL                                            $320.7          $235.2

We recorded product sales of $320.7 million in the first quarter of 2002, a 36% increase over 2001 levels of $235.2 million,
primarily due to increased sales of Synagis. Synagis, our largest product, accounted for approximately 91% and 94%, respectively, of
our 2002 and 2001 first quarter product sales. Sales of Synagis for the quarter ended March 31, 2002 increased 32% over the
comparable 2001 period. Contributing to the growth in 2002 sales was a 35% increase in domestic Synagis sales to $287.0 million in
2002 from $212.1 million in 2001. The growth was attributable to increased demand in the United States, resulting in a 32% increase
in domestic sales unit volumes, and a 3.1% price increase in June 2001. International sales of Synagis decreased to $6.1 million in
the 2002 quarter versus $9.4 million in the 2001 quarter. The Company's international sales volume decreased 86% during the 2002
quarter as compared to the 2001 quarter. The Company believes that the decrease is due to reductions in the inventory stocking
levels of our international distributor, Abbott International ("Abbott"), rather than reduced product demand by end users. The
decrease in unit volume was offset by an increase in the per unit sales price recognized upon delivery of product to Abbott under
the terms of our international distribution agreement. Effective May 1, 2001, the terms of the distribution agreement (a) mandated
an increase in the transfer price and (b) requires the entire purchase price to be payable upon delivery of product to Abbott. Under
the revised terms, the price earned by the Company is determinable at the time of delivery. Under the previous contract terms, the
Company invoiced Abbott and recognized revenue on sales to Abbott when Synagis was delivered based on a contractually stipulated
transfer price, which approximated 60 percent of the ultimate revenue value to us. Following the end of each quarter, Abbott
remitted a report to us detailing end-user sales for the quarter along with an additional amount due in excess of the transfer
price. We recognized revenue for the additional amount due in excess of the transfer price at that time. We have been working with
Abbott to expand the number of countries where we are licensed to sell Synagis. As of February 1, 2002, international registrations
have been filed in 58 countries for the approval of Synagis, for which approval in the United States and 46 foreign countries had
been obtained, the most recent of which was Japan in January 2002. There can be no assurance that approvals by the appropriate
regulatory authorities will continue to be granted. Additionally, we may not receive pricing and reimbursement approvals in
countries where we have received regulatory approval.

We have also achieved increases in Ethyol sales since we reacquired domestic marketing rights to Ethyol from ALZA in October
2001.  Ethyol accounted for approximately 6% and 1% of our first quarter product sales in 2002 and 2001, respectively.  Ethyol
revenues increased from $3.3 million in the first quarter of 2001 to $18.2 million in the first quarter of 2002.  Domestic Ethyol
sales were $16.8 million in the 2002 quarter, of which we believe a portion was wholesaler stocking in anticipation of an April
price increase.  As of October 1, 2001, we record all revenues from domestic sales of Ethyol and, beginning April 1, 2002, we
will pay ALZA a declining royalty for nine years thereafter based on sales of Ethyol in the U.S.  Prior to October 1, 2001, we
had recorded Ethyol domestic product sales based on a price of 25% to 35% of ALZA's net unit selling price.  Our international
sales of Ethyol to our distribution partner, Schering-Plough Corporation ("Schering"), of $1.4 million were consistent with the
prior year quarter.  We record Ethyol international product sales based on a percentage of Schering's end user sales.

CytoGam accounted for approximately 2% of our first quarter 2002 product sales, compared to 3% in 2001.  First quarter CytoGam
sales decreased to $7.2 million in 2002 from $8.0 million in 2001.  Domestic sales units decreased 5%, which was partially offset
by a domestic price increase of 10% which took effect during the first quarter of 2002.   We recorded no international sales of
CytoGam during first quarter 2002 versus $1.4 million in the 2001 quarter.  First quarter 2002 sales reflect CytoGam's use in
transplantation, our core business.  We expect that sales for the year 2002 will be flat versus the prior year.

Sales of other products in first quarter 2002, which include sales of NeuTrexin, RespiGam, and by-products that result from the
CytoGam manufacturing process, were comparable with the 2001 quarter's sales.

The level of future product sales will be dependent on several factors, including, but not limited to, the timing and extent of
future regulatory approvals of our products and product candidates, availability of finished product inventory, approval and
commercialization of competitive products and the degree of acceptance of our products in the marketplace.

Other Revenues - Other revenues for the quarter ended March 31, 2002 decreased to $9.0 million, from $10.0 million in the 2001
period.  Other revenues during both years include revenues under collaborative agreements.  We recognized revenue of $2.6 million
and $5.5 million for the first quarter of 2002 and 2001, respectively, related to upfront and milestone payments under these
agreements.  For up-front and milestone payments received prior to 2002, we recognized non-refundable fees and milestone payments
in connection with research and development and commercialization agreements as the contractual obligations and performance
requirements are fulfilled, using the contingency-adjusted performance model for revenue recognition.  Under this method, the
amount of revenue recognized during each period is based on a percentage of completion model of actual costs incurred relative to
the total projected costs.  The expected timing of annual revenues to be recognized through 2005 under the major collaborative
agreements for which we have deferred a portion of the upfront and milestone payments received, based on current estimates of
costs to complete, are as follows (in thousands):

                                                      2002          2003         2004         2005
                                                      ----          ----         ----         ----
Abbott Laboratories                                  $7,500        $2,700         $--          $--
GlaxoSmithKline                                         700            --          --           --

                                                     ------        ------       -----        -----
Total                                                $8,600        $3,100        $400         $400
                                                     ======        ======       =====        =====

Future changes in estimated total costs or differences between actual costs and projected costs in any one period could cause the
actual recorded amounts to differ from the projected amounts.  As discussed in the notes to the financial statements, we have
adopted the milestone payment method for new contracts entered into after January 1, 2002.  Since adopting the new method, we
have not entered into any new contracts in which we have received upfront or milestone payments.  Because we have adopted this
method prospectively, the table above assumes the revenues deferred will be recognized in accordance with the contingency
adjusted performance model.  The milestone payment method may not be applicable to all new contracts, in which case the Company
would revert to the contingency adjusted performance model for revenue recognition.

Other revenues in the 2002 period also include $2.9 million under an agreement entered into during 2001 to sell excess production
capacity to a third party, $1.7 million in reimbursement from Wyeth relating to our collaborative agreement for FluMist, and $1.2
million from MGI Pharma related to the agreement for the sale of our Hexalen business. Other revenues in the 2001 period also
include $1.2 million from MGI Pharma related to the agreement for the sale of our Hexalen business, $1.5 million in research
funding from GlaxoSmithKline ("GSK") for the development of an HPV vaccine, and revenues for royalty income from ALZA in
accordance with the terms of the Ethyol distribution agreement.  The level of contract revenues in future periods will depend
primarily upon the extent to which we enter into other collaborative contractual arrangements, if any, and the extent to which we
achieve certain milestones provided for in existing agreements.

Cost of Sales - Cost of sales for the first quarter of 2002 increased 51% to $79.9 million from $52.8 million in 2001 due to
increases in sales volumes.  Gross margins for the 2002 quarter decreased to 75% from 78% in the March 2001 quarter principally
as a result of additional royalties payable relating to Synagis.  The increase in royalties was offset slightly by improved
margins due to the implementation of an improved manufacturing process at the Frederick Manufacturing Center ("FMC") which
increases Synagis yields (the "enhanced yield process").  We expect that gross margins may vary significantly from quarter to
quarter, based on the product mix.  We expect that on an annual basis, our gross margin percentage for 2002 should be lower than
2001, as a result of the additional royalties owed for Synagis and expenses for manufacturing operations of Aviron subsequent to
possible FDA approval of FluMist, which may or may not be granted.

Research and Development Expenses - Research, development and clinical expenses for the first quarter increased $25.4 million, or
136% to $44.1 million in the 2002 quarter, from $18.7 million in the 2001 quarter.  The increase reflects a larger number of
active clinical trials and the inclusion of on-going Aviron research, development and clinical expenses in our results.  To
accommodate the additional activity, we expanded our workforce and facilities, resulting in increased wages and occupancy
expense.  Additionally, we incurred approximately $3.3 million in expense in the 2002 quarter relating to retention payments,
stock option acceleration and stock compensation for unvested stock options assumed in conjunction with the Aviron merger.
Currently, our clinical trial program includes eleven projects in various phases of clinical evaluation, a Phase 3 study of
Synagis in infants with congenital heart disease and a trial in adults using a liquid formulation of Synagis; one Phase 1 and
four Phase 2 trials with our human papillomavirus (HPV) cervical cancer vaccine; three Phase 2 trials with MEDI-507 in psoriasis
patients; two Phase 2 trials for our urinary tract infection (UTI) vaccine; and a Phase 1 trial with Vitaxin in cancer and
rheumatoid arthritis.

We expect clinical spending to increase significantly over 2001 levels in the coming quarters as more of our product candidates
move  into the clinic and we expand trials on products already in the clinic.   In February 2002, we entered into a research
collaboration with Panacea Pharmaceuticals, Inc. ("Panacea") to license technology relating to Human Aspartyl (Asparaginyl)
(beta)-Hydroxylase ("HAAH"), an enzyme that is over-expressed by many types of cancer.  In conjunction with the agreement, the
Company makes quarterly research and development funding payments to Panacea and is obligated to pay up to $34.1 million in
various milestone payments subject to the achievement of specified clinical and regulatory and sales milestones.

The development-stage efforts listed above and other research and development projects may never reach clinical trials, achieve
success in the clinic, be submitted to the appropriate regulatory authorities for approval, or be approved for marketing or
manufacturing by the appropriate regulatory authorities.  Further, we rely on numerous third parties to assist us in various
stages of the development process.  Should they be unable to meet our needs, we may incur substantial additional costs.  Any of
such uncertainties, if they should occur, could have a material adverse effect on our financial condition and results of
operations.

Selling, General, and Administrative Expense - Selling, general and administrative ("SG&A") expense increased $35.9 million, or
60% in the first quarter of 2002 to $95.6 million as compared to $59.7 million in the first quarter of 2001.  As a percentage of
product sales, SG&A expense increased to 30% in 2002 from 25% in 2001.  The increase in this ratio is largely reflective of
ongoing expenses relating to Aviron, which, to date, has no product sales.  Additionally, we incurred $1.6 million in expense in
the 2002 quarter relating to retention payments, stock option acceleration and stock compensation for unvested stock options
assumed and $1.7 million for amortization of intangibles in conjunction with the Aviron merger.  In 2002, we also incurred
increased salary and related expenses for the expansion of our Ethyol sales force by adding approximately 40 additional sales
representatives and increasing our marketing expenses for the relaunch of Ethyol during the second half of 2001.  SG&A expense
also increased due to costs for expanded Synagis marketing programs, sales commissions and increased co-promotion expense to the
Ross Products Division of Abbott Laboratories for the promotion of Synagis in the United States.  Co-promotion expense is based
on a percentage of net domestic sales of Synagis and thus increases as net domestic Synagis sales increase.  Additionally, we
experienced  increases in legal costs, as we are currently involved in several litigation matters (see further discussion in the
Legal Proceedings section of this report).  For 2002, we expect SG&A expenses to approximate 2001 as a percentage of total
revenues.

Other Operating Expenses - Other operating expenses, which reflect manufacturing start-up costs and other manufacturing related
costs, increased in the 2002 quarter to $21.8 million from $2.1 million in the 2001 quarter. The increase is principally
attributable to charges associated with Aviron's start-up manufacturing operations for FluMist.  These charges will continue to
be recorded to other operating expense until FDA approval of  FluMist, which may or may not be granted.  In addition, we incurred
$5.6 million in expense in the 2002 quarter relating to retention payments, stock option acceleration and stock compensation for
unvested stock options assumed and $2.0 million for amortization of intangibles relating to our merger with Aviron. Subsequent to
FDA approval of FluMist, if granted, Aviron's manufacturing costs will be expensed to cost of sales.  Also included in other
operating expense for both periods are costs associated with our Frederick manufacturing facility.  The plasma production section
of our Frederick manufacturing facility has excess capacity, which results in charges to other operating expenses.  These charges
are expected to continue for the foreseeable future until the plasma production section of the facility is fully utilized.

In-Process Research and Development - We incurred charges of $1,179.3 million during the first quarter of 2002 for the write-off
of purchased in-process research and development in conjunction with our acquisition of Aviron.  The write-off represents the
fair value of purchased in-process technologies at the acquisition date, calculated utilizing the income approach, of certain
in-process research and development projects, primarily FluMist.  FluMist is a live, attenuated vaccine delivered via a nasal
mist for the prevention of influenza.  We are currently seeking regulatory approval for the frozen formulation, which requires
freezer storage.  While there are other flu vaccines currently marketed by other companies, FluMist would be the only live virus
vaccine administered as a nasal mist available in the United States.  As of the date of the merger, Aviron had submitted a
biologic license application ("BLA") for FluMist (frozen) to the FDA seeking approval for licensure.  The BLA was submitted to
the FDA in October 2000.  Aviron received a Complete Response Letter from the FDA on August 31, 2001, and filed its response to
this letter on January 8, 2002.  We are working to achieve approval of the product for the 2002-2003 flu season; however, we
cannot guarantee that approval will be obtained for the 2002-2003 flu season, or at all.  The liquid formulation of FluMist,
which is better suited to international markets, is currently in Phase 3 clinical trials with our international partner, Wyeth.
The Company does not anticipate that there will be any alternative future use for the in-process technologies that were written
off.  In valuing the purchased in-process technologies, the Company used probability-of-success-adjusted cash flows and a
discount rate of 18.4%. Based on current information, management believes that the revenue projections underlying the analysis
are substantially accurate. As with all biotechnology products, the probability of commercial success for any one research and
development project is highly uncertain.  In addition, as of March 31, 2002, none of the existing manufacturing facilities
involved in the production of FluMist had been licensed by any regulatory agency and FluMist had not yet been manufactured at a
sustained commercial scale.  There can be no assurance that these facilities can achieve licensure by the FDA or any other
regulatory agency.  Nor can there be any assurances that if licensed, commercial scale production could be achieved or
sustained.  If we fail to obtain FDA approval for the marketing and manufacture of FluMist, we will absorb all of Aviron's
ongoing expenses while recording no corresponding revenue.

Interest Income and Expense - We earned interest income of $11.9 million during the 2002 quarter versus $10.2 million in 2001
quarter, reflecting higher cash balances available for investment, partially offset by a decline in interest rates which lowered
our portfolio yield.  Interest expense for the first quarter of 2002 increased $2.6 million over first quarter 2001.  The
increase relates to interest expense on Aviron's convertible debt included in our operating results.

Taxes -  We recorded income tax expense of $34.9 million for the quarter ended March 31, 2002.  Excluding the write-off of
purchased in-process research and development, which is not deductible for tax purposes, income tax expense resulted in an
effective tax rate of 35.9%.  This compares to tax expense of $43.3 million recorded for the quarter ended March 31, 2001, based
on an effective tax rate of 35.5%.  The variation in the effective tax rate for 2002 versus 2001 results from differences in the
amount of credits taken for research and development activities and credits earned for orphan drug status of certain research and
development activities.  These credits will vary from year to year depending on the activities of the Company.  In addition, due
to state tax law changes that occurred during 2001, our statutory tax rate decreased to 37.0%.  We believe that our year-to-date
effective tax rate for 2002 will be slightly below our statutory rate of 37.0%.

Net earnings -  Net loss for the first quarter of 2002 was $1,116.9 million, or $4.54 per share, compared to earnings for the
2001 quarter of $78.7 million, or $0.37 basic and $0.36 diluted earnings per share.  Shares used in computing net loss per share
for the quarter ended March 31, 2002 were 245.8 million and shares used for computing basic and diluted earnings per share for
the quarter ended March 31, 2001 were 212.2 million and 219.8 million, respectively.

Our quarterly financial results may vary significantly due to seasonality of Synagis product sales, fluctuations in sales of
other products, milestone payments, research funding and expenditures for research, development, clinical and marketing
programs.  Synagis sales are expected to occur primarily during, and in proximity to, the RSV season, which typically occurs
between October and April in the United States.  No assurances can be given that adequate product supply will be available to
meet demand.

LIQUIDITY AND CAPITAL RESOURCES

Sources and uses of cash-  The Company's capital requirements have generally been funded from operations, cash and investments on
hand, and issuance of common stock.  Cash and marketable securities were $1,335.2 million at March 31, 2002 versus $787.7 million
December 31, 2001, an increase of 70%.  Increases in cash are due to cash generated by operations and cash acquired in
conjunction with the Aviron merger.  Working capital increased to $689.3 million at March 31, 2002, from $429.9 million at
December 31, 2001.

Operating Activities

Net cash provided by operating activities increased to $148.7 million in the three months ended March 31, 2002 as compared to
$130.6 million in the comparable 2001 period, primarily as the result of net earnings for the period (excluding the write-off of
in-process research and development and other non-cash items) and increases in accrued liabilities, net of increases in trade
accounts receivable.  The increase in accrued expenses primarily results from increased amounts due to Abbott Laboratories for
Synagis co-promotion expense, due to the increase in domestic Synagis sales.  The Company also expended cash for restructuring
payments relating to the Aviron acquisition.  The remaining restructuring liability of $2.4 million is expected to be settled by
2004.  Payments are expected to be made from cash generated from operations.

Investing Activities

Cash used for investing activities during the first quarter of 2002 amounted to $40.2 million, as compared to $26.5 million in
2001.  Cash used for investing activities in 2002 included net additions to our investment portfolio of $161.7 million, offset by
$146.9 in cash assumed as a result of our merger with Aviron.  We also invested $2.2 million in preferred equity securities of a
strategic partner, Panacea,  related to the in-licensing of the HAAH technology,  and $23.1 million for capital expenditures,
primarily for the construction of our new corporate headquarters, and for the continued expansion of our manufacturing facilities
in Frederick and the Aviron facilities in the U.K. and Philadelphia, Pennsylvania.

During March 2002, we paid approximately $13.4 million to acquire 25 acres of land in Gaithersburg, Maryland, which will serve as
the site of our new corporate headquarters.  We have contracted with a designer and general contractor for the construction of
the new facility over the next several years, at a total estimated cost of $85 million, to be funded from net cash from
operations and investments on hand.  Construction began during March 2002, and the Company expects to take occupancy of the first
phase, a complex of approximately 218,000 square feet, in the fall of 2003.  At that time, the Company expects to sublease its
existing space.

In conjunction with the research and development collaboration with Panacea, the Company is obligated to pay up to $34.1 million
in various milestone payments subject to the achievement of specified clinical, regulatory, and sales milestones and is obligated
to make quarterly research and development funding payments.  Payments due are expected to be funded from net cash from
operations and investments on hand.

Financing Activities

Financing activities generated $18.0 million in cash for the first quarter of 2002, as compared to $9.1 million in 2001.
Approximately $18.2 million was received upon the exercise of employee stock options in 2002, as compared to $9.3 million
received in 2001, reflecting the inclusion of option exercises of Aviron.  In 2002 and 2001, repayments on long-term debt were
$0.2 million.

ITEM 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Following the Company's acquisition of Aviron, Aviron remains obligated for its outstanding indebtedness, which included $200.0
million aggregate principal amount of 5 1/4% Convertible Subordinated Notes (the "Notes") due 2008.  The Notes were recorded at fair
value of $211.4 million as of the acquisition date, based on quoted market prices.  Interest is payable semi-annually in arrears
in cash on January 15 and July 15 each year.  Changes in interest rates do not affect interest expense incurred on the Notes,
because they bear interest at fixed rates.  The Notes are convertible into an aggregate of 3.4 million shares of the Company's
common stock, based on a conversion price of $58.14, at any time on or before January 15, 2008.  Aviron may redeem the Notes
beginning in January 2004, at the redemption prices declining from 103% of their principal amount in 2004 to 100% in 2008, plus
accrued interest.

The Company periodically enters into foreign exchange forward contracts which permit the Company to purchase Euros to fund a
portion of its inventory purchase obligations at a fixed exchange rate.  As of March 31, 2002, the Company had outstanding
forward Euro contracts in the amount of $8.0 million, all expiring within one year.  Fair value of the outstanding contracts at
March 31, 2002 was $(0.1) million.

Qualitative Disclosures About Market Risk" of the Company's Annual Report on Form 10-K for the year ended December 31, 2001.

                                                     --------------------

The statements in this quarterly report that are not descriptions of historical facts may be forward-looking statements.  Those
statements involve substantial risks and uncertainties.  You can identify those statements by the fact that they contain words
such as "anticipate," "believe," "estimate," "expect," "intend," "project" or other terms of similar meaning.  Those statements
reflect management's current beliefs, but are based on numerous assumptions which MedImmune cannot control and which may not
develop as MedImmune expects.  Consequently, actual results may differ materially from those projected in the forward - looking
statements.  Among the factors that could cause actual results to differ materially are:  seasonal demand for and continued
supply of the Company's principal product, Synagis; whether FluMist receives clearance by the Food and Drug Administration and,
if it does, whether it will be successfully launched; availability of competitive products in the market; availability of
third-party reimbursement for the cost of our products; effectiveness and safety of our products; exposure to product liability,
intellectual property or other types of litigation; foreign currency exchange rate fluctuations; changes in generally accepted
accounting principles; growth in costs and expenses; the impact of acquisitions, divestitures and other unusual items; and the
risks, uncertainties and other matters discussed in this quarterly report and in our periodic reports filed with the U.S.
Securities and Exchange Commission.  MedImmune cautions that RSV disease occurs primarily during the winter months; MedImmune
believes its operating results will reflect that seasonality for the foreseeable future.  MedImmune is also developing several
products (including FluMist) for potential future marketing.  There can be no assurance that such development efforts will
succeed, that such products will receive required regulatory clearance or that, even if such regulatory clearance were received,
such products would ultimately achieve commercial success.  Unless otherwise indicated, the information in this quarterly report
is as of March 31, 2002.  This quarterly report will not be updated as a result of new information or future events.


                                                                  PART II
                                                             OTHER INFORMATION

Item 1.           Legal Proceedings

In 1998, MediGene AG ("MediGene") initiated a legal action against Loyola University of Chicago ("Loyola") and the Company in the
U.S. District Court for the Northern District of Illinois alleging, among other things, breach of contract and tortious
interference by the Company with an alleged prospective business relationship between MediGene and Loyola. The claims relate to
human papillomavirus vaccine technology allegedly covered by contracts between MediGene and the Company and by a license
agreement from Loyola to the Company, under which the Company granted a sublicense to GlaxoSmithKline.  MediGene seeks damages
from the Company ranging from $31.3 million to $86.9 million based on the tortious interference claim, and/or damages ranging
from $10.2 million to $31.3 million based on the breach of contract claim.  MediGene also seeks ownership of the patents in
question, as well as rescission of the Company's license agreement from Loyola or rights as a third-party beneficiary thereof.
On December 22, 2000 and March 15, 2001, the District Court granted summary judgment motions in favor of the Company on all
claims.  The District Court ordered entry of final judgment in favor of the Company on March 19, 2002.  On March 27, 2002
MediGene filed a notice of appeal to the United States Court of Appeals for the Federal Circuit.

In October 2000, Celltech Chiroscience Limited ("Celltech") commenced a legal proceeding against the Company in the U.K. High
Court of Justice, Chancery Division, Patents Court.  Celltech alleges that the Company failed to pay royalties with respect to
its sales of Synagis as required by a license agreement dated January 19, 1998.  Under the agreement, the Company obtained from
Celltech a worldwide license to make, use and/or sell product under a patent (and related applications) pertaining to humanized
antibodies.  In the proceeding, Celltech seeks payment of a 2% royalty based on net sales of Synagis sold or manufactured in the
United States, with interest, and certain costs, including attorney's fees.  The Company has filed answering papers denying that
any royalties are due on the basis that Celltech's U.S. patent does not cover Synagis and has sought dismissal of the case on the
grounds that the legal doctrine of prosecution history estoppel prevents Celltech from claiming that its patent covers Synagis.
On July 20, 2001, the High Court of Justice ordered a hearing, which is expected to take place in late 2002 or early 2003, on
whether it will dismiss Celltech's case on this basis.  On November 29, 2001, the Company received a letter from counsel for
Celltech enclosing a copy of a patent granted by the European Patent Office on November 14, 2001.  That letter requested various
information concerning the manufacture and sale of Synagis in Europe and sought confirmation that the Company would pay royalties
on such sales pursuant to the license agreement dated January 19, 1998.  As of March 25, 2002, the Company had not made the
royalty payments that were the subject of Celltech's letter, and Celltech had not initiated any legal proceeding against the
Company based on its European patent.

On December 18, 2001, Genentech, Inc. ("Genentech") announced that it had been granted a patent relating to certain methods and
compositions used to produce antibodies by recombinant DNA technology.  In June 1997, in anticipation of any potential impact
the issuance of Genentech's patent could have on the production of Synagis, the Company obtained a license to this patent.  The
Company has received from Genentech a letter, dated January 7, 2002, stating that Genentech expects to receive from the Company
royalty payments pursuant to such license. The Company is in the process of evaluating whether any valid claim of Genentech's
patent, as recently issued, covers production of Synagis.  If so, the Company would pay royalties to Genentech on U.S. net sales
of Synagis commencing December 18, 2001. Pending resolution of this issue, the Company has made certain royalty payments to
Genentech under protest and with reservation of all of its rights.  The Company is also evaluating whether any of its other
antibody-based product candidates, if and when approved for marketing by the U.S. Food and Drug Administration, could require a
license under the Genentech patent.

On February 28, 1996, Ichthyol Gesellschaft Cordes, Hermanni & Co. ("Ichthyol Gesellschaft") filed a complaint for refrain,
information and damages with the Regional Court of Hamburg against MedImmune Oncology on the grounds of trademark infringement in
respect of the use of the trademark "Ethyol" in Germany.  No monetary amount is currently being sought in the litigation by
Ichthyol.  Ichthyol is seeking injunctive relief against the use of the trademark Ethyol in Germany.  The suit was dismissed on
January 29, 1997 by the Regional Court of Hamburg.  Ichthyol Gesellschaft filed an appeal and a  judgment was rendered in favor
of MedImmune Oncology in the appellate proceedings.  In January 1999, Ichthyol Gesellschaft filed an appeal on points of law with
the Federal Court of Justice, and in June 1999, Ichthyol Gesellschaft filed the grounds for the appeal on points of law.  By
judgment of May 3, 2001, the Federal Court of Justice reversed the judgment of the Higher Regional Court and remitted the case to
that court for another hearing.  By order of December l9, 2001, the Higher Regional Court ordered Ichthyol to make further
submissions concerning the relevant facts and legal questions.  Ichthyol recently filed its submissions.  Another hearing will
probably be held this summer.

After consultation with its counsel, the Company believes that it has meritorious defenses to the claims referred to above and is
determined to defend its position vigorously.  While it is impossible to predict with certainty the eventual outcome of these
proceedings, the Company believes they are unlikely to have a material adverse effect on its financial position but might have a
material adverse effect on its results of operations for a particular period.

On April 5, 2002, the Company filed a suit against Centocor, Inc. ("Centocor") in the United States District Court for the
District of Maryland.  The Company currently pays Centocor a royalty for sales of Synagis made or sold in the United States
pursuant to a patent Sublicense Agreement between the parties dated as of September 15, 2000 (the "Sublicense Agreement").  In
the litigation, the Company seeks a declaratory judgment that it has no obligation to continue paying royalties to Centocor on
the basis that the patent is invalid, unenforceable and does not cover Synagis.  Additionally, the Company seeks an injunction
preventing Centocor from enforcing this patent.  There can be no assurance that the Company will be successful in this litigation.
