The Company has  purchased  plasma and other raw materials for use in production
in the Company's Frederick manufacturing facility, which is subject to U.S. Food
and Drug Administration  ("FDA") licensure and approval.  Due to the uncertainty
surrounding  the likelihood  and timing of FDA approval, all inventory for
this facility has been  classified as  noncurrent  in the  accompanying  balance
sheet.

As a result of the June 1998 FDA approval of the Company's second generation RSV
product,  Synagis,  and the market  acceptance of Synagis,  the Company reserved
approximately  $9.2 million against its RespiGam inventory in the second quarter
of 1998,  as no further  significant  product  sales are expected to result from
this inventory in the foreseeable  future.  As of March 31, 1999,  approximately
$8.0 million of the reserve remains.  The remaining RespiGam plasma inventory of
$2.7 million has been  written down to the value the Company  expects to recover
upon sale to third  parties.  Should the Company be unable to sell the plasma at
its net  book  value,  a  further  adjustment  in a  subsequent  quarter  may be
necessary.

Finished  goods at March 31, 1999 and December  31, 1998  include  approximately
$1.6 million of  by-products  that result from the  production  of the Company's
principal products at one of its contract manufacturers and are held for resale.
The March 31,  1999 and  December  31,  1998  balances  are net of a reserve of
$1.6 million.

Construction  in progress  includes costs incurred in connection with the design
and   construction  of  the  Company's   manufacturing   facility  and  includes
capitalized  interest  costs of $6.0  million and $5.3 million at March 31, 1999
and December 31, 1998, respectively.

Buildings includes the purchase in December 1998 of a new facility in Frederick,
Maryland.  This  facility  is  expected  to  provide  additional  warehouse  and
administrative space. Buildings also includes costs associated with the portions
of  the  Company's   manufacturing  facility  placed  in  service  during  1998.
Construction  of the  manufacturing  facility is  complete  and  validation  and
start-up activities are ongoing.  The Company will continue to capitalize costs,
primarily capitalized interest, related to the facility until placed in service.
The portions of the facility that are subject to inspection  and approval by the
FDA will be placed in service and  depreciation  will  commence  upon receipt of
such approval.

Income Tax Provision
The income tax  provision  in the  current  quarter has been  computed  using an
effective  combined  federal and state tax rate of 38.6%. The cash obligation of
such provision has been offset by the utilization of deductions generated by the
exercise of stock  options and the  utilization  of  deferred  taxes,  comprised
mostly of net  operating  loss  carryforwards. As required,  the tax benefit of 
stock option exercise deductions has been recorded directly to stockholders'
equity.

Earnings per Share
The  Company  computes  earnings  per  share in  accordance  with  Statement  of
Financial  Accounting  Standards  ("SFAS") 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 and the dilutive common stock
equivalents  outstanding  during the period.  The dilutive effect of convertible
debt is measured using the "if converted"  method.  The dilutive effect of stock
options is measured  using the treasury stock 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 numerators and denominators of the diluted
EPS computation for the periods reported.

New Accounting Pronouncement
Derivative Instruments and Hedging Activities
In June  1998,  the  FASB  issued  SFAS  No.  133,  "Accounting  for  Derivative
Instruments and Hedging  Activities".  SFAS No. 133  establishes  accounting and
reporting  standards for derivative  instruments,  including certain  derivative
instruments embedded in other contracts and for hedging activities. SFAS No. 133
requires companies to recognize all derivatives as either assets or liabilities,
with the instruments  measured at fair value. The accounting for changes in fair
value,  gains or losses,  depends on the intended use of the  derivative and its
resulting  designation.  The statement is effective  for all fiscal  quarters of
fiscal years  beginning after June 15, 1999. The Company will adopt SFAS No. 133
by  January  1,  2000.  Because of the  Company's  minimal  use of  derivatives,
management  does not  anticipate  that the  adoption of SFAS No. 133 will have a
material effect on the earnings or financial position of the Company.

ITEM 2.
                                 MEDIMMUNE, INC.
                  MANAGEMENT'S DISCUSSION AND ANALYSIS OF
               FINANCIAL CONDITION AND RESULTS OF OPERATIONS

RESULTS OF OPERATIONS
THREE MONTHS ENDED MARCH 31, 1999 AND 1998

Product sales  increased 196% to $127.0 million in first quarter 1999 from $42.9
million in first quarter  1998,  principally  due to sales of Synagis.  Sales of
Synagis  for the 1999  quarter  were  $116.2  million  and during the  1998/1999
respiratory  syncytial virus ("RSV") season totaled  $226.0  million.  Synagis
sales in the first quarter of 1999 included $1.5 million of international  sales
to  the  Company's  exclusive  international   distributor  of  Synagis,  Abbott
Laboratories. RespiGam sales of $0.3 million were recorded in first quarter 1999
versus $32.1  million in first quarter  1998,  reflecting  the shift in customer
demand from  RespiGam to Synagis for  prevention of RSV disease and adequate 
levels of  inventories of  RespiGgam at wholesalers  and  hospitals.  CytoGam  
sales decreased 10% to $9.7 million in the 1999  quarter from $10.8  million in 
first quarter 1998 reflecting a change in  the  sales  mix  of  domestic  versus
international  units,  (international  units have a lower selling  price) and an
increase in government rebate allowances, offset by a 9% increase in total units
sold.  Product sales in the 1999 quarter also include $0.8 million of by-product
sales.  Other  revenues  in the 1999  first  quarter of $1.7  million  primarily
reflect  payments from SmithKline  Beecham ("SKB") for development of a human
papillomavirus  vaccine  while the 1998 quarter  included a $15.0 million
payments from SKB upon signing of the collaborative alliance.

Gross  margins  improved  to 75% in the first  quarter of 1999 versus 48% in the
first quarter of 1998. Gross margins in 1999 were favorably  impacted by Synagis
sales,  which  carry a  significantly  lower  per-unit  cost than the  Company's
plasma-derived products.

Research, development and clinical spending increased 55% to $8.8 million in the
first quarter of 1999 from $5.7 million in the first  quarter of 1998.  Expenses
in 1999 include costs of the Company's  congenital  heart disease clinical trial
using Synagis and various clinical studies relating to MEDI-507, the Company's
anti-CD2 monoclonal antibody.  

Selling,  administrative and general expenses increased to $37.0 million in this
year's  quarter from $12.9  million in the 1998  quarter,  an increase of 187%.
Expenses in 1999 include  increased  marketing  and selling  expenses as well as
commission  charges and co-promotion  expenses to the Ross Products  Division of
Abbott  Laboratories,  all in connection with the launch and continued promotion
of  Synagis.  Marketing,  selling  and  co-promotion  expenses  for  Synagis are
expected to continue to be higher than those for RespiGam or CytoGam.

                                       8


Other operating  expenses of $5.9 million in the 1999 period increased from $5.8
million in the 1998 period.  Costs in 1998 include  scale-up of  production  for
Synagis at a  third-party  manufacturer  as well as start-up  activities  at the
Company's pilot plant and Frederick Manufacturing Center ("FMC"), while costs in
1999 include ongoing start-up and validation activities at the FMC.

Interest  income of $2.2 million was earned in the 1999 first quarter,  compared
to $1.7 million in the first  quarter of 1998  reflecting  higher cash  balances
available for investment, partially offset by a decrease in interest rates which
lowered the overall  portfolio yield.  Interest expense of $1.0 million and $1.2
million was  incurred in the 1999 and 1998  quarters,  respectively,  reflecting
primarily  interest due on the Company's  convertible  debt,  net of capitalized
interest.

An income tax  provision of $18.2  million was recorded for the first quarter of
1999. No income tax provision was recorded in the first quarter of 1998,  due to
the  existence  of net  operating  loss  carryforwards  as well  as  uncertainty
surrounding achievement of profitability for the entire year.

Net earnings in the 1999 first  quarter were $28.8  million,  or $0.52 basic and
$0.45  diluted  earnings per share.  Shares used in computing  basic and diluted
earnings per share in 1999 were 55.2 million and 65.5 million, respectively. Net
earnings  for the first  quarter  of 1998  were  $0.25  basic and $0.22  diluted
earnings  per share.  Shares used in  computing  basic and diluted  earnings per
share in 1998 were 51.9 million, and 63.2 million shares, respectively.

Quarterly financial results may vary significantly due to seasonality of Synagis
product sales as well as  fluctuations  in CytoGam  sales,  milestone  payments,
research  funding and  expenditures  for research,  development  and  marketing.
Synagis sales are expected to occur primarily  during,  and in proximity to, the
RSV  season,   which  typically  occurs  in  the  Northern Hemisphere  between
October and April. The Company believes that most of the Synagis needed for the 
1998/1999 RSV season in the U.S. was purchased prior to the end of the first
quarter 1999, and therefore, no further significant sales are expected for this
season.

LIQUIDITY AND CAPITAL RESOURCES

Cash and marketable securities at March 31, 1999 were $194.1 million compared to
$134.9  million at 1998 year end. Net cash  provided by operating  activities in
the  three  months  ended  March  31,  1999 was  $61.0  million,  reflecting
primarily  the net  earnings  for the 1999  quarter  and an  increase in accrued
expenses and royalties  payable.  Capital  expenditures of $1.6 million,  net of
capitalized  interest,  for the quarter were  primarily  for lab  equipment  and
facilities   expansion   and   improvements   at  the   Company's   Gaithersburg
manufacturing facility. The Company's existing funds at March 31, 1999, together
with funds expected to be generated  from product sales and  investment  income,
are expected to provide  sufficient  liquidity to meet the anticipated  needs of
the business for the foreseeable future, absent the occurrence of any unforeseen
events.

                                       9


YEAR 2000 READINESS

The  Company  has   established   a  Year  2000   Project   Team   comprised  of
representatives  from key functional  areas to complete a review of its internal
and external systems for Year 2000 readiness. The Year 2000 issue is expected to
affect the systems of the Company  and various  entities  with which the Company
interacts,  including the Company's  marketing  partners,  suppliers and various
vendors.  The Year 2000 Project is designed to address  three major  areas:  (1)
information  technology systems,  (2) hardware,  equipment and  instrumentation,
including  embedded systems,  and (3) third party  relationships.  The Company's
plan involves  inventorying,  assessing and prioritizing  those items which have
Year  2000  implications;   remediating  (repairing,   replacing  or  upgrading)
non-compliant items; testing items with major exposure to ensure compliance; and
developing  contingency plans to minimize potential business  interruption.  The
inventory,  assessment and prioritization  phase of the project is substantially
complete.

With regard to the Company's information technology systems, hardware, equipment
and   instrumentation,   the  Company  has  identified   mission   critical  and
non-critical items and is in the process of updating and/or replacing items that
are non-compliant.  The Company believes that it should be able to substantially
complete  implementation  of critical aspects of its Year 2000 plan prior to the
commencement  of the year 2000.  Because  the Company  has relied  primarily  on
off-the-shelf  software for its information technology needs and because much of
the hardware,  equipment and instrumentation is currently compliant, the Company
does not  anticipate  that the costs for  internal  remediation  efforts will be
significant.  The Company does not  separately  track the internal  costs of its
Year 2000 compliance efforts and therefore these costs are unknown.  As of March
31,  1999,  the  Company  estimates  that  it has  spent  no more  than  $75,000
replacing,  upgrading  or  repairing  the  systems  and/or  equipment  that  are
non-compliant  and expects the cost to complete  these efforts should not exceed
$300,000. The Company presently anticipates that its remediation efforts will be
substantially  complete by June 1, 1999.  Testing of certain  business  critical
items is expected to be completed by the third quarter 1999.

In addition to the risks  associated with the Company's own computer systems and
equipment,  the  Company  has  relationships  with,  and is in  varying  degrees
dependent upon, a large number of third parties that provide information,  goods
and services to the Company.  These include, but are not limited to, third party
manufacturers,   suppliers,   customers,  and  distributors.   The  Company  has
identified and visited the facilities of third parties with whom the Company has
material relationships to assess their Year 2000 readiness. Critical systems and
Year 2000 plans were  reviewed.  The Company may also be affected by the failure
of other third parties to be Year 2000 compliant even if they do not do business
directly  with the  Company.  For  example,  the  failure of state,  federal and
private  payers or reimbursers to be Year 2000 compliant and thus unable to make
timely,  proper or  complete  payments  to  sellers  and users of the  Company's
products,  could have a material  adverse effect on the Company.

The Company does not currently have a Year 2000  contingency  plan  established.
The Company expects to have finalized a contingency  plan which will address the
most likely  worst case Year 2000  scenario by mid- 1999.  The Company  believes
that its most likely worst case  scenario  would be delays in product  shipments
due to a complete or partial manufacturing  shutdown. To mitigate this risk, the
Company plans, among other things, to stock extra inventory.

With  regard  to  the  Company's  Year  2000  readiness  plan,  there  can be no
assurances:  1) that the  Company  will be able to  identify  all aspects of its
business  that are  subject  to Year  2000  problems,  including  issues  of its
customers or suppliers,  2) that the Company's  software vendors,  third parties
and others will be correct in their assertions that they are Year 2000 ready, 3)
that the  Company's  estimate  of the cost of Year  2000  readiness  will  prove
ultimately  to be  accurate,  4) that the Company  will be able to  successfully
address its Year 2000 issues and that this could result in interruptions  in, or
failures of, certain normal  business  activities or operations  that may have a
material  adverse  effect on the Company's  business,  results of operations and
financial condition.
