MedImmune ("the Company") is a biotechnology company focused on
developing and marketing products for infectious diseases and
transplantation medicine. Since commencing operations in 1988,
the Company has pursued a strategy of establishing an initial
commercial base using proven technologies and targeting
well-understood diseases to support longer-term product
development. This strategy has relied on the advancement of an
internally developed pipeline of product candidates and on
in-licensing products from third parties.

The Company is currently marketing two products, CytoGam
(Cytomegalovirus Immune Globulin Intravenous (Human), CMV-IGIV)
and RespiGam (Respiratory Syncytial Virus Immune Globulin
Intravenous (Human), RSV-IGIV).  The Company has established core
competencies in transplantation and infectious diseases and has a
research and development portfolio which includes six products
now

<PAGE>1

undergoing clinical trials, including two in Phase 3 studies and
a number of product candidates in preclinical development.

Products on the Market.
RespiGam
RespiGam is marketed for the prevention of serious respiratory
syncytial virus ("RSV") disease in children under 24 months of
age with a lung condition called bronchopulmonary dysplasia
("BPD") or a history of premature birth (i.e., born at 35 weeks
or less gestation). RespiGam is the only product demonstrated to
be safe and effective in reducing the incidence and duration of
RSV hospitalization and the severity of RSV illness in these high
risk infants.

RespiGam is a specialty immune globulin purified from donor
plasma screened to have high levels of neutralizing antibodies
against RSV. RSV is the leading cause of pneumonia and
bronchiolitis in children and results in an estimated 90,000
hospitalizations and 4,500 deaths annually in the United States.
RSV outbreaks occur worldwide, usually during the late fall,
winter and early spring. Certain populations of infants, children
and adults are at increased risk for developing severe RSV
disease. These include severely premature infants (i.e., less
than or equal to 32 weeks gestation) and infants with BPD. There
are approximately 100,000 children in this high-risk group in the
United States.

The Company directly markets RespiGam in the leading 420 neonatal
and pediatric hospitals in the United States. These hospitals
comprise approximately 70% of the total potential business for
RespiGam.  The Company's direct marketing efforts are
supplemented

<PAGE>2

by the Wyeth-Lederle Vaccines and Pediatrics sales force of Wyeth-
Ayerst Laboratories (a division of American Home Products
Corporation ("AHP")), one of the leading pharmaceutical companies
focused on pediatric medicine. AHP has focused on promoting
RespiGam to physicians in smaller hospitals and to office-based
pediatricians.  The Company submitted an application to Canadian
regulatory authorities during 1996 to request approval to market
RespiGam.  There can be no assurance that such a license will be
granted, or, if granted, that licensure will occur in a timely
manner.

The Company has established a collaboration with Baxter
Healthcare Corporation ("Baxter"), one of the leading producers
and marketers of immune globulins worldwide, to commercialize
RespiGam outside North America.  The Company has been advised
that Baxter expects to file regulatory applications in Europe
during 1997 seeking a license to market RespiGam throughout
Europe (see "Collaborative Agreements").  There can be no
assurances that such a license or licenses will be granted, or,
if granted, that licensure will occur in a timely manner.

After receiving approval from the United States Food & Drug
Administration ("FDA") for the marketing of RespiGam in January
1996, the Company launched RespiGam for its first full RSV season
during fourth quarter 1996.  Sales of RespiGam in the fourth
quarter were $13.9 million.  The Company was supply-constrained
in the fourth quarter and expects to be limited in its supply of
RespiGam in the first quarter 1997.  The Company has worked
closely with its contract manufacturers to increase product
supply for the 1997-1998 RSV season.  While the Company believes
it will

<PAGE>3

be successful in achieving this goal, there can be no assurances
that demand will not exceed supply during subsequent RSV seasons.

CytoGam
CytoGam is marketed for the attenuation of primary
cytomegalovirus ("CMV") disease associated with kidney
transplantation.  Approximately 75% of untreated donor-
positive/recipient-negative kidney transplant recipients are
expected to develop CMV disease. Infection of a transplant
recipient with CMV by a donor organ is associated with increased
mortality and substantial morbidity including pneumonia,
hepatitis, opportunistic infections and possibly graft rejection.
CytoGam is a specialty immune globulin product enriched in
antibodies against CMV.  CytoGam has been shown to reduce the
incidence of severe CMV disease and opportunistic infections
associated with kidney transplantation.  The Company began
marketing CytoGam through its own hospital-based sales force in
1993. Sales of CytoGam have grown at a compounded annual rate of
approximately 30% since 1993 to $18.4 million in 1996.  While
sales growth has been strong, the Company expects to continue to
face increasing pressure from cost containment efforts as well as
competition from other effective anti-viral therapies.

Products in Development
MEDI-493 RSV Monoclonal Antibody
MEDI-493 is a humanized monoclonal antibody being evaluated in
clinical studies for the prevention of RSV disease in high-risk
infants (see "RespiGam" above). MEDI-493 is administered by
intramuscular injection and consequently has the potential to
enhance patient care, reduce costs associated with drug
administration and improve convenience for parents, physicians
and

<PAGE>4

nurses.  Taken together, the Company believes these benefits may
provide the potential to reach a broader population of children
with MEDI-493 than with RespiGam.

The Company has tested MEDI-493 in Phase 1 and Phase 2 clinical
trials involving approximately 300 patients for both prevention
and treatment of RSV disease.  During the 1996-1997 RSV season,
the Company is evaluating MEDI-493 in a Phase 3 clinical trial,
IMpact-RSV, being conducted at 139 medical centers in 1,502 high-
risk infants and children in the United States, Canada and the
United Kingdom.  The Company expects to complete the trial in May
1997 and announce results during the third quarter.  While the
Company believes it has established a rapid and comprehensive
development program for MEDI-493, substantial risk remains,
including: 1) no assurances can be given that the clinical trial
will show with statistical significance that MEDI-493 is safe and
effective in preventing RSV-associated hospitalization; 2)no
assurances can be given that an observed effect, if any, will be
great enough to warrant commercialization; 3)no assurances can be
given that the FDA will license the drug for marketing; and 4)no
assurances can be given that if FDA licensure occurs, it would
occur in a timely manner.  To date, the Company has retained
exclusive worldwide marketing and manufacturing rights for MEDI-
493.

Human Papillomavirus Vaccine
Human papillomaviruses ("HPVs") are responsible for the
development of genital warts and cervical cancer.  There are
currently no vaccines to prevent these common sexually
transmitted diseases that affect 24 to 40 million men and women

<PAGE>5

in the United States.  There are over 75 different types of HPV
associated with a variety of clinical disorders ranging from
benign lesions to potentially lethal cancers.  Four types of HPV
cause the majority of genital warts and cervical cancer cases:
HPV-6, HPV-11, HPV-16 and HPV-18.

The Company's first HPV vaccine candidate, MEDI-501, is composed
of the HPV-11 L1 capsid protein which self assembles into virus-
like particles (VLPs).  The VLPs, which are produced in vitro
using recombinant DNA technology, imitate the structure of
natural papillomavirus, but are not infectious.  When presented
to the immune system, VLPs may be able to elicit a similar immune
response to that seen with naturally occurring HPV.  Scientists
at the Company, in collaboration with a team at Georgetown
University, have shown the potential effectiveness of a VLP
vaccine candidate using a dog model for papillomavirus infection.
The model involves a virus called canine oral papillomavirus
(COPV) which mimics HPV infection closely because it produces
both warts and tumors at a mucosal site.  In December 1995, The
Company and its collaborators published in "The Proceedings of
the National Academy of Sciences" the results of studies which
indicated that a COPV VLP vaccine preparation was able to protect
dogs against COPV warts.  That study provided the scientific
rationale for developing an analogous vaccine for humans.

The Company began a Phase 1 clinical trial with MEDI-501 in
February 1997 to evaluate its safety, tolerance, and
immunogenicity.  The trial, which is being conducted at the
University of Rochester Medical Center, is expected to conclude
in approximately 12 months.  The Company expects to begin testing

<PAGE>6

of vaccine candidates for other types of HPVs in the next 12 to
18 months including HPV-18, HPV-16 and HPV-6. The Company
believes a multi-component vaccine consisting of two or more HPV
types would be necessary to prevent HPV disease of the genital
tract.

Monoclonal Antibodies for Transplantation Medicine
The Company is developing several monoclonal antibodies for use
in transplantation medicine. There are approximately 19,000 solid
organ transplants and 11,000 bone marrow transplantation
procedures annually in the United States.  Despite significant
improvements in the transplantation arena, life-threatening
complications such as graft-vs.-host disease ("GvHD") and organ
rejection remain serious medical problems.

BTI-322 is a rat anti-CD2 monoclonal antibody being developed by
the Company in collaboration with BioTransplant, Incorporated for
various applications in transplantation medicine.  In studies
conducted to date, involving over 60 patients in the United
States and Europe, BTI-322 has shown initial promise in its
ability to prevent and treat organ graft rejection and to treat
GvHD.  BTI-322 is currently being evaluated in a multi-center
Phase 2 clinical trial for the treatment of acute GvHD.  Safety,
efficacy and pharmacokinetic parameters are being monitored
during the study which is expected to be completed within one
year.

Laboratory studies have suggested that BTI-322 primarily inhibits
the response of T cells directed at transplant antigens while
subsequently allowing immune cells to respond normally to other

<PAGE>7

antigens.  The specificity and long lasting effects of this
inhibition suggest that BTI-322 could have potential utility in
applications other than transplantation, such as in autoimmune
diseases.  The Company is currently developing MEDI-507, a
humanized form of the product, which is expected to enter
clinical trials in 1997 for selected applications in
transplantation and autoimmune diseases.  Autoimmune diseases are
of major medical importance worldwide and include common
afflictions like rheumatoid arthritis, multiple sclerosis and
Crohn's disease.

In 1994, the Company in-licensed from the University of Kentucky
a murine monoclonal antibody known as T10B9 (now MEDI-500).  MEDI-
500 suppresses most T cells by binding to a protein (the alpha-
beta receptor) on the surface of the T cell.  MEDI-500 has been
evaluated in several transplantation clinical trials involving
approximately 400 individuals.  A Phase 2 clinical trial
comparing MEDI-500 with the only commercially available
monoclonal antibody for treatment of acute rejection suggested
that MEDI-500 may have a similar efficacy profile but with
reduced side effects.  A Phase 3 clinical trial, sponsored by the
National Heart, Lung, and Blood Institute ("NHLBI"), is currently
evaluating MEDI-500 for prevention of graft-versus-host disease
(GvHD).

Lyme Disease Vaccine
Lyme disease is the most common arthropod-borne disease in the
United States.  Virtually every state within the U.S. has
reported cases of Lyme disease, with an annual nationwide
reported incidence of nearly 14,000 new cases in 1996, a 30-40%

<PAGE>8

increase over 1995. Lyme disease is also reported in Europe,
Japan, China, Russia and Australia.  The disease is caused by a
bacterium know as Borrelia burgdorferi ("B. burgdorferi") and is
transmitted through a tick, Ixodes scapularis, which is most
commonly found on the white-footed mouse or deer.

The Company in-licensed a newly characterized B. burgdorferi
protein called decorin binding protein ("Dbp") from Texas A&M
University, which initial animal studies suggest may provide
protection against B. burgdorferi infection.  Unlike antibodies
to vaccines in development by other companies, Dbp antibodies can
be given to mice during the early phase of infection and still
clear the bacterium from animals.  This may allow a significantly
greater window of opportunity for a protective immune response to
clear infection.  The Company believes Dbp is the only protein
identified from B. burgdorferi to date for which this effect has
been demonstrated. In addition, antibodies from animals immunized
with Dbp inhibited growth of many strains of the Lyme disease-
causing bacteria not inhibited by antibodies to another vaccine
candidate in development, including some species of Lyme bacteria
commonly found outside the United States.  These results suggest
that Dbp may provide an improved Lyme disease vaccine candidate
or, alternatively, a supplement to the vaccine candidates
currently in development.

Urinary Tract Infection Vaccine
Urinary tract infections ("UTIs") commonly require medical
attention in women and children.  Escherichia coli ("E. coli")
strains are the main causative agents of UTIs. While many factors
contribute to the acquisition and progression of UTIs, it is

<PAGE>9

widely accepted that colonization of the urogenital tract by
pathogenic bacteria is a prerequisite for disease. A number of
studies have pointed to a role for pilus proteins, the long
filamentous protein appendages on the surface of E. coli, in
mediating attachment to host cells.  Certain proteins located at
the distal tip of the pilus, called "adhesins," have been
implicated in this attachment, providing an important novel
target for vaccine development.

The Company and its collaborators at Washington University in St.
Louis are developing antibacterial candidates based on the tip
adhesins on the E. coli pili.  The FimH adhesin which is at the
tip of UTI-associated pili, binds to mannose receptors
distributed throughout the human bladder.  In preliminary
experiments at the Company, the FimH adhesin protein elicited a
strong antibody response in mice.  These antibodies inhibited
attachment to human bladder cells in vitro in greater than 90% of
different E. coli clinical UTI isolates tested.  Furthermore,
anti-FimH antibodies reduced bladder colonization by UTI-
associated E. coli in a mouse model.  Taken together these data
suggested that the FimH adhesin could potentially serve as a
target for an anti-bacterial vaccine to combat UTIs.

The Company is currently conducting in vivo animal model studies
and designing large scale production and purification protocols
for its first UTI vaccine candidate.  Adhesin-based vaccines may
also be an effective strategy for other diseases caused by
bacteria.

Streptococcus pneumoniae Vaccine

<PAGE>10

Streptococcus pneumoniae is a major cause of pneumonia, middle-
ear infections and meningitis worldwide, especially in the very
young or elderly.  Pneumonia causes more than one million deaths
per year and is the most common cause of childhood death in
developing countries.  In  industrialized countries, pneumococcal
pneumonia is a serious problem among the elderly.  Middle-ear
infections affect almost every child at least once during the
first 2 years of life.  Vaccination against pneumococcal
infections has become more urgent in recent years due to the
emergence of antibiotic-resistant strains throughout the world.

The Company has recently established a collaboration with The
Rockefeller University ("Rockefeller") in New York to develop
products for the prevention and treatment of Streptococcus
pneumoniae infection.  The Company has been granted a worldwide
exclusive license to commercialize product candidates developed
from a novel set of genes discovered by scientists at
Rockefeller.  In addition, research efforts are underway by
scientists at the Company and Rockefeller to identify novel
conserved surface proteins for potential vaccine applications.
During 1997, promising candidate proteins are expected to be
evaluated in a number of in vitro and in vivo models to determine
their potential as vaccine candidates.

Other Infectious Disease Products
The Company has several additional efforts in place to develop
vaccines for common viral and bacterial infectious diseases
including B19 parvovirus, Haemophilus influenzae and
Staphylococcus aureus.

<PAGE>11

Discovered in 1975, B19 parvovirus has been linked to a number of
serious conditions including certain types of miscarriages in
pregnant women, life-threatening sudden reduction of red blood
cells in sickle cell anemia patients, chronic anemia in AIDS and
chemotherapy patients, and persistent arthritis in some adults.
MEDI-491 is a vaccine intended to prevent human B19 parvovirus
infection.  Like MEDI-501, MEDI-491 utilizes virus-like particle
("VLP") technology. By producing two natural B19 parvovirus
proteins in the correct proportions in an insect cell recombinant
protein production system, the Company and collaborators at the
National Heart, Lung, and Blood Institute ("NHLBI") are able to
generate VLPs which resemble the natural B19 parvovirus
particles, but are not infectious.  The Company has completed a
Phase 1 clinical trial to evaluate the safety of MEDI-491. The
Company believes that a successful B19 parvovirus vaccine could
be used to immunize women entering their child-bearing years to
protect them from experiencing risk of B19 parvovirus-induced
miscarriages.  Alternately, a successful B19 parvovirus vaccine
could be incorporated into routine childhood immunization
programs to reduce the prevalence of this virus.

Haemophilus influenza ("H. influenzae") causes otitis media or
middle ear infections in young children.  There are more than
700,000 cases in the United States each year and many infections
recur.  As part of MedImmune's ongoing collaboration with Human
Genome Sciences, Inc. ("HGS"), the genome of H. influenzae has
been sequenced and approximately 90 novel surface proteins have
been identified as potential vaccine candidates.  These candidate
proteins are currently being evaluated by MedImmune scientists.

<PAGE>12

Staphylococcus aureus ("S. aureus") is a bacterium which infects
over nine million individuals each year in the United States, and
is the most frequent cause of infections in the hospital.  A
significant percentage of all hospital-acquired S. aureus
infections are now resistant to most antibiotics. To date, 99% of
the genome has been sequenced and over 3,000 genes have been
identified as part of MedImmune's ongoing collaboration with HGS.
Novel candidates are being selected for evaluation.

(1)  "Phase  1" and "Phase  2" clinical trials generally involve
     administration of a product to a limited number of patients

 <PAGE>14

     to evaluate safety, dosage and, to some extent, efficacy.
     "Phase  3" clinical trials generally examine the efficacy
     and safety of a product in an expanded patient population at
     multiple clinical sites.

(2)  AHP co-promotes RespiGam in the United States. Baxter holds
     a license to commercialize RespiGam outside North America,
     and the Company would receive a royalty on any sales by
     Baxter.

(3)  This product is being developed by AHP. The Company is
     entitled to a royalty on any sales, if and when licensed for
     marketing by the FDA.

Marketing, Research, Development and Collaborative Agreements
The Company's internal research programs are augmented by
collaborative projects with its scientific partners.  As part of
its strategy, the Company has established alliances with
pharmaceutical and other biotechnology companies, academic
scientists and government laboratories. Currently, its principal
strategic alliances are the following:

American Home Products Corporation.
In November 1993, the Company entered into a strategic alliance
with American Cyanamid Company ("ACY") to co-develop and
co-promote products for the treatment and prevention of RSV and
to co-promote ZOSYN(1), an anti-infective developed by ACY. In 1994,
American Home Products Corporation ("AHP") acquired ACY and in
October 1995, AHP invested $15 million in the Company through the

(1) ZOSYN is a trademark of American Home Products Corporation.

<PAGE>15

purchase of 967,742 shares of Common Stock. The Company and AHP
collaborated on the development of RespiGam and AHP is
co-promoting the product. In connection with the October 1995
investment, the Company and AHP agreed to amend certain terms of
agreements entered into concurrently with the formation of their
1993 strategic alliance. Pursuant to these amendments, AHP's
funding obligations and co-promotion rights with respect to
MEDI-493 were terminated, and the Company returned its right to
co-promote ZOSYN. In addition, the Company's obligation to
co-fund and co-promote an RSV vaccine being developed by AHP was
converted into the right to receive royalties on any sales of
this vaccine, and AHP was granted the right to receive royalties
on any sales of MEDI-493.


Baxter Healthcare Corporation.
In June 1995, the Company entered into an exclusive,
royalty-bearing license agreement with Baxter Healthcare
Corporation ("Baxter") to commercialize RespiGam outside North
America. Within its territory, Baxter will be responsible for
funding clinical and regulatory activities and for manufacturing
and marketing RespiGam. Upon the achievement of certain sales
milestones, Baxter is obligated to reimburse the Company for
certain previously funded research and development activities.
Concurrent with the execution of the license agreement, Baxter
also purchased 826,536 shares of Common Stock for $9.5 million.

BioTransplant, Incorporated.
In October 1995, the Company and BioTransplant, Incorporated
("BTI") formed a strategic alliance for the development of

<PAGE>16

products to treat and prevent organ transplant rejection. The
alliance is based upon the development of products derived from
BTI's anti-CD2 antibody BTI-322, the Company's anti-T cell
receptor antibody MEDI-500 and future generations of products
derived from these two molecules (such as MEDI-507, or humanized
BTI-322). Pursuant to the alliance, the Company received an
exclusive worldwide license to develop and commercialize BTI-322
and any products based on BTI-322, with the exception of the use
of BTI-322 in kits for xenotransplantation or
allotransplantation. The Company has paid BTI $4 million in
license fees and research support to date.  The Company has
assumed responsibility for clinical testing and commercialization
of any resulting products. BTI will receive research support and
milestone payments which could total up to an additional $12
million, as well as royalties on any sales of BTI-322, MEDI-500,
MEDI-507 and future generations of these products, if any.

Human Genome Sciences, Inc.
In July 1995, the Company entered into a collaborative research
and development relationship with Human Genome Sciences, Inc.
("HGS") to create antibacterial vaccines and immunotherapeutic
products based upon the genomic sequences of bacteria. The
Company and HGS initiated collaborative research efforts with
programs to develop vaccines for non-typeable Haemophilus
influenzae and Staphylococcus aureus.  Rights to another genomic
sequence for vaccine development, Helicobacter pylori, were out-
licensed to Oravax, Inc. and Pasteur Merieux Connaught in
November 1996 for license payments as well as milestone and
royalty obligations. Additional research projects for the
development of vaccines and antibody-based products will be
determined as additional genomic

<PAGE>17

sequences are completed of other bacteria selected by the Company
and HGS. Pursuant to a collaboration and license agreement
between the Company and HGS, the Company will be solely
responsible for the commercialization of any products developed
through the collaboration, and HGS will be entitled to royalties
based upon the extent to which any products jointly developed are
covered by patents or license rights held by HGS.

Massachusetts Health Research Institute and Massachusetts Public
Health Biologics Laboratories.
In August 1989 and April 1990, the Company entered into a series
of research, supply and license agreements with Massachusetts
Health Research Institute ("MHRI") and Massachusetts Public
Health Biologics Laboratories ("MPHBL") covering products
intended for the prevention or treatment of CMV and RSV infection
and other respiratory virus infections by immune globulins or
monoclonal antibodies. The Company has agreed to pay royalties on
all sales using the licensed technology. Pursuant to the
agreements, the Company paid $11.8 million in 1996, $5.1 million
in 1995 and $4.9 million in 1994, for royalties, process
development and manufacturing.

Other Agreements.
The Company has a number of other collaborative and business
agreements with academic institutions and business corporations,
including agreements with 1) Washington University in St. Louis
covering development of pilus-based anti-bacterial vaccines, 2)
Georgetown University, the German Cancer Research Center and the
University of Rochester covering development of vaccines for
human papillomaviruses and 3) Rockefeller University for the
discovery

<PAGE>18

and commercialization of products to treat and prevent
Streptococcus pneumoniae. In addition, the Company has license
agreements with third parties on CytoGam, RespiGam, MEDI-493 and
substantially all of its other potential products. The Company is
obligated to pay royalties on any sales of these products.

Marketing and Sales
The Company is developing a sales and marketing organization
which it believes is responsive to the increased importance of
managed care, the need to lower costs and the necessity to
provide quality service to its customers.

The Company's first product, CytoGam, was originally marketed by
a third party as the Company's exclusive distributor. In
December 1992, the Company reacquired marketing rights to CytoGam
and in January 1993, the Company commenced marketing of CytoGam
in the United States through its own 14-person sales force
focused on 250 leading transplantation hospitals. Sales outside
the United States are made through regional distributors.

After the expansion of the sales and marketing teams in January
1996, the Company now has approximately 70 people in these
groups. The Company has five regional business directors, each
with 15 or more years of sales, marketing or managed care
experience, to manage the regional business units. Approximately
45 sales and managed care representatives cover approximately 500
hospitals and clinics in the United States which specialize in
transplantation and/or pediatric/neonatal care for the promotion
of CytoGam and RespiGam, respectively.  Each sales representative
is responsible for selling both CytoGam and RespiGam.

<PAGE>19

The Company's RespiGam sales effort is supplemented by the
approximately 300-person Wyeth-Lederle Vaccines and Pediatrics
sales force of the Wyeth-Ayerst Laboratories (a division of AHP).
While the Company focuses on the top 420 leading neonatal and
pediatric medical centers in the United States (accounting for
approximately 70% of potential RespiGam sales), AHP focuses on
smaller hospitals and pediatrician offices.  AHP is among the
leading pharmaceutical companies focused on pediatric medicine.

The Company has established a collaboration with Baxter, one of
the leading producers and marketers of immune globulins
worldwide, to commercialize RespiGam outside North America, if
and when licensed for marketing by foreign regulatory
authorities.  The Company has been advised that Baxter intends to
file European regulatory applications during 1997 to request a
license to market RespiGam in Europe.  There can be no assurance
that such a license will be granted, or, if granted, that
licensure will occur in a timely manner.

Manufacturing and Supply
The Company has entered into manufacturing, supply and purchase
agreements in order to provide a supply of human plasma and
production capability for CytoGam and RespiGam. CytoGam and
RespiGam are produced from human plasma collected from donors who
have been screened to have higher concentrations of antibodies
against CMV and RSV, respectively. Human plasma for CytoGam and
RespiGam is converted to an intermediate raw material (Fraction
II+III paste) under a supply agreement with Baxter.  The Company
has recently entered into an agreement with V.I. Technologies,

<PAGE>20

Inc. to supply additional Fraction II+III paste.

MPHBL processes the Fraction II+III paste into bulk product. The
Company has an informal arrangement with MPHBL for planned
production of bulk product for CytoGam and RespiGam. MPHBL holds
the sole product and establishment licenses for CytoGam and
RespiGam.  The Company also has an agreement with Connaught
Laboratories, Inc. ("Connaught") to fill and package CytoGam and
RespiGam.  If MPHBL, the suppliers of the Fraction II+III paste,
or Connaught is unable to satisfy the Company's product
requirements on a timely basis or is prevented for any reason
from manufacturing CytoGam or RespiGam, the Company may be unable
to secure an alternative supplier or manufacturer without undue
and materially adverse operational disruption and increased cost.
Currently, RespiGam finished product inventory is in short
supply, and no assurances can be given that an adequate supply
will be available to meet demand. Recently, the Company has
experienced product shortages which have limited product sales
without reducing sales and marketing costs.

In July 1996, the Company entered into an engineering,
procurement, construction and validation services agreement with
Fluor Daniel, Inc. ("Fluor") to design and construct a
manufacturing facility to be located on a 26 acre site in
Frederick, Maryland. The Company estimates the facility will cost
approximately $50 million to construct. The facility is planned
to be a multi-use biologics facility intended to provide
production capability for the manufacture of immune globulins
(CytoGam and RespiGam) and by-products from human plasma. In
addition, the facility is being designed to contain a cell
culture production

<PAGE>21

area for the manufacture of products, such as MEDI-493, MEDI-500
and BTI-322, if and when they are licensed for marketing by the
FDA. There can be no assurance that the facility will receive
regulatory approval for its intended purposes. Additionally,
construction and validation of manufacturing facilities can take
substantial time to complete. In order to produce RespiGam in the
manufacturing facility, the Company may need to obtain certain
rights from MPHBL.  No assurances can be given that such rights
can be obtained.  Additionally, no assurances can be given that
if the technology to manufacture CytoGam and/or RespiGam is
transferred to the Company from MPHBL, that the Company will
successfully be able to produce these products in the plant.

The Company produces materials for clinical trials in its pilot
plant facility in Gaithersburg, Maryland. Materials currently
being used in clinical trials for MEDI-490, MEDI-493, MEDI-491
and MEDI-500 have been produced at the Company's pilot plant.
Completion is expected in 1997 of an expansion of the Company's
pilot plant facility to support the production of materials for
Phase 3 clinical trials and market entry production requirements.
The Company estimates the cost of expanding this facility to be
approximately $6 million. There can be no assurance that when the
facility is completed, appropriate regulatory approvals will be
obtained to use the facility for market entry manufacturing.

Patents, Licenses and Proprietary Rights
Products currently being developed or considered for development
by the Company are in the area of biotechnology, an area in which
there are extensive patent filings. The patent position of
biotechnology firms generally is highly uncertain and involves

<PAGE>22>

complex legal and factual questions. To date, no consistent
policy has emerged regarding the breadth of claims allowed in
biotechnology patents. Accordingly, there can be no assurance
that patent applications owned or licensed by the Company will
result in patents being issued or that, if issued, such patents
will afford protection against competitors with similar
technology. In addition, there can be no assurance that products
covered by such patents, or any other products developed by the
Company or subject to licenses acquired by the Company, will not
be covered by third party patents, in which case continued
development and marketing of such products would require a
license under such patents. There can be no assurance that such
required licenses will be available to the Company or its
licensees on acceptable terms.

The Company is aware of several patents and patent applications
which may affect the Company's ability to make, use and sell the
Company's products or product candidates, including the
following: (i) three United States patents, directed to
intravenous immune globulin containing high concentrations of
either CMV or RSV antibodies, which have been issued to a major
pharmaceutical company having substantially greater financial
resources than the Company and (ii) United States patents,
directed to murine monoclonal antibodies against T cells and the
use thereof, which have been issued to another major
pharmaceutical company having substantially greater financial
resources than the Company.  Although the Company believes that
neither its CytoGam and RespiGam technologies, which use
intravenous immune globulins containing high concentrations of
CMV or RSV antibodies, respectively, nor its MEDI-500 and BTI-322
technologies, which use monoclonal antibodies against T cells,
infringe any valid claims

<PAGE>23

of such patents, the Company can provide no assurances that if a
legal action based on such patents were brought against the
Company, such an action would be resolved in the Company's favor.
If such a dispute were resolved against the Company, in addition
to potential damages, the manufacturing and sale of such products
could be enjoined unless a license were obtained. There can be no
assurances that, if a license were required, such a license would
be made available on terms acceptable to the Company.
Additionally, the Company is aware of several patents covering
the composition of and process for making murine and humanized
monoclonal antibodies for which the Company may need a license or
licenses.  If such a license or licenses were required, there can
be no assurance that companies holding such licenses would make
them available to the Company on terms acceptable to the Company.

While the Company has several licenses to issued patents and owns
or has licenses to pending patent applications with respect to
certain of its products, the Company believes that there are
other patents issued to third parties and/or patent applications
filed by third parties which could have applicability to each of
the Company's products and product candidates and which could
adversely affect the Company's freedom to make, use or sell such
products or use certain processes for their manufacture. The
Company is unable to predict whether it will ultimately be
necessary to seek a license from such third parties or, if such a
license were necessary, whether such a license would be available
on terms acceptable to the Company. The necessity for such a
license could have a material adverse effect on the Company's
business.

<PAGE> 24

There has been substantial litigation regarding patent and other
intellectual property rights in the biotechnology industry.
Litigation may be necessary to enforce certain intellectual
property rights of the Company. Any such litigation could result
in substantial cost to and diversion of effort by the Company.

Government Regulation
The production and marketing of the Company's products and
research and development activities are subject to regulation for
safety and efficacy by numerous governmental authorities in the
United States and other countries. In the United States,
vaccines, drugs and certain diagnostic products are subject to
FDA review and licensure. The federal Food, Drug and Cosmetics
Act, the Public Health Service Act and other federal statutes and
regulations govern or influence the testing, manufacture, safety,
labeling, storage, record keeping, licensure, advertising and
promotion of such products. No assurances can be given that any
products under development will be licensed for marketing by the
FDA or once approved, that the product will be successfully
commercialized or maintained in the marketplace. Non-compliance
with applicable requirements can result in fines, recall or
seizure of products, total or partial suspension of production,
refusal of the government to approve product license
applications, restrictions on the Company's ability to enter into
supply contracts and criminal prosecution. The FDA also has the
authority to revoke product licenses and establishment licenses
previously granted.

The FDA may designate a drug as an Orphan Drug for a particular
use, in which event the developer of the drug may be entitled to a

<PAGE>25

seven year marketing exclusivity period. CytoGam and RespiGam
have been designated as Orphan Drugs for certain indications by
the FDA. Accordingly, CytoGam and RespiGam have market
exclusivity for their currently licensed indications through
April 17, 1997 and January 17, 2003, respectively.

The Company is also subject to regulation by the Occupational
Safety and Health Administration ("OSHA") and the Environmental
Protection Agency ("EPA") and to regulation under the Toxic
Substances Control Act, the Resources Conservation and Recovery
Act and other regulatory statutes, and may in the future be
subject to other federal, state or local regulations. OSHA and/or
the EPA may promulgate regulations concerning biotechnology that
may affect the Company's research and development programs. The
Company is unable to predict whether any agency will adopt any
regulation which would have a material adverse effect on the
Company's operations. The Company voluntarily attempts to comply
with guidelines of the National Institutes of Health regarding
research involving recombinant DNA molecules. Such guidelines,
among other things, restrict or prohibit certain recombinant DNA
experiments and establish levels of biological and physical
containment that must be met for various types of research.

Sales of pharmaceutical and biopharmaceutical products outside
the United States are subject to foreign regulatory requirements
that vary widely from country to country. Whether or not FDA
licensure has been obtained, licensure of a product by comparable
regulatory authorities of foreign countries must be obtained
prior to the commencement of marketing the product in those
countries. The time required to obtain such licensure may be
longer or shorter than

<PAGE>26

that required for FDA approval, and no assurances can be given
that such approval will be obtained.

Competition
The biotechnology and pharmaceutical industries are characterized
by rapidly evolving technology and intense competition. The
Company's competitors include pharmaceutical, chemical and
biotechnology companies, many of which have financial, technical
and marketing resources significantly greater than those of the
Company. In addition, many specialized biotechnology companies
have formed collaborations with large, established companies to
support research, development and commercialization of products
that may be competitive with those of the Company. Academic
institutions, governmental agencies and other public and private
research organizations are also conducting research activities
and seeking patent protection and may commercialize products on
their own or through joint ventures.

The Company is aware of certain products manufactured by
competitors that are used for the prevention or treatment of
certain diseases the Company has targeted for product
development, including CMV, RSV, Lyme disease, HPV infections and
organ graft rejection. For example, in the prevention of CMV
disease, the Company's CytoGam competes with several other
products including intravenous ganciclovir, manufactured by
Hoffmann-La Roche Inc. The Company is aware that a number of
physicians have prescribed CytoGam in combination with
ganciclovir for the prevention of CMV disease in certain
patients. Recently, three new drugs have been launched relating
to CMV prophylaxis and treatment: 1) Hoffmann-La Roche Inc.
received an FDA license to market a more convenient

<PAGE>27

oral formulation of ganciclovir for prevention of CMV disease in
solid organ transplant recipients and individuals with advanced
HIV infection at risk for developing CMV disease, 2)Chiron
Corporation received an FDA license to market an implant that
would deliver ganciclovir directly to the eye to treat AIDS
patients with CMV retinitis, and 3)Gilead Sciences, Inc. received
an FDA license to market intravenous cidofovir for the treatment
of CMV retinitis in AIDS patients. The Company believes that for
the prevention of RSV disease, the Company's RespiGam does not
compete directly with any product; however, the Company is aware
of one product in the U. S., ribivirin, which is indicated for
the treatment of RSV disease. The existence of these products, or
other products or treatments of which the Company is not aware,
or products or treatments that may be developed in the future,
may adversely affect the marketability of products developed by
the Company. In addition, the Company is aware of other
companies, such as OraVax, Inc., which are developing products
for the treatment and prevention of RSV. These products may
compete directly with RespiGam and may offer relative benefits,
such as ease of administration.

The Company expects its products to compete primarily on the
basis of product efficacy, safety, patient convenience,
reliability, price and patent position. In addition, the first
product to reach the market in a therapeutic or preventive area
is often at a significant competitive advantage relative to later
entrants to the market. The Company's competitive position will
also depend on its ability to attract and retain qualified
scientific and other personnel, develop effective proprietary
products, implement

<PAGE>28

product and marketing plans, obtain patent protection and secure
adequate capital resources.

                 AND RELATED SHAREHOLDER MATTERS

The Company's common stock trades on The Nasdaq Stock Market
under the symbol "MEDI".  At February 28, 1997, the Company had
382 common stockholders of record.  This figure does not
represent the actual number of beneficial owners of common stock
because shares are generally held in "street name" by securities
dealers and others for the benefit of individual owners who may
vote the shares.  The following table shows the range of high and
low closing prices and year end closing prices for the common
stock for the two most recent fiscal years.

   ITEM 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
               CONDITION AND RESULTS OF OPERATIONS

This review contains management's discussion of the Company's
operational results and financial condition and should be read in
conjunction with the accompanying financial statements.

OVERVIEW
     MedImmune commenced operations in April 1988 and, through
1990, revenue was generated solely from research and development
<PAGE>32
agreements and research grants.  In 1991, contract revenues rose
substantially and the Company began selling its first product,
CytoGam, to an exclusive distributor.  In December 1992, the
Company reacquired the CytoGam marketing rights from its
distributor and launched an expanded marketing program for this
product through its own sales force.
     On January 18, 1996, the Company's second product, RespiGam
was licensed for marketing by the U.S. Food and Drug
Administration ("FDA") for the prevention of serious lower
respiratory tract infection caused by RSV in children under 24
months of age with BPD or a history of prematurity. AHP's Wyeth-
Lederle Vaccines and Pediatrics sales force co-promotes RespiGam
in the United States. Because of the seasonal nature of RSV,
limited sales, if any, are expected during the second and third
quarters.
     To date, product sales have not produced sufficient revenues
to cover the Company's operating expenses.  Consequently, the
Company has experienced substantial operating losses.  While
results may vary significantly from quarter to quarter, the
Company does not expect to be profitable for the year at least
through 1998.

RESULTS OF OPERATIONS
     1996 Compared to 1995
     The increase in product sales for the year ended December
31, 1996 as compared to the year ended December 31, 1995 is due
to the commencement of sales of RespiGam in 1996 and a 14%
increase in CytoGam sales.  RespiGam sales were $17.3 million in
1996, of which $13.9 million were generated in the fourth
quarter.  CytoGam product sales increased to $18.4 million from
$16.2 million in 1995 due primarily to increased units sold.
CytoGam product sales were reduced by a $0.7 million reserve in
the 1996 third quarter for trade receivables due from a
pharmaceutical wholesaler which filed Chapter 11 bankruptcy in
August 1996.  Although the Company markets directly to hospitals
and physicians, the Company sells its products through a limited

<PAGE>33

number of pharmaceutical wholesalers and a similar event with
another wholesaler could adversely affect operating income.  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 the Company's products and product
candidates, availability of finished product inventory, approval
and commercialization of competitive products and the degree of
acceptance of the Company's products in the marketplace.
Currently, RespiGam finished product inventory is in short
supply, and no assurances can be given that an adequate supply
will be available to meet demand.
     Contract revenue decreased to $5.3 million in 1996 from
$11.3 million in 1995, reflecting the completion of milestone and
research funding payments under the Company's strategic alliance
with AHP, formerly American Cyanamid Company.  Under the terms of
the alliance, the Company and AHP will share in the profits or
losses of RespiGam; reimbursements or payments under this
arrangement are deducted from or added to operating expenses.
The level of contract revenues in future periods will depend
primarily upon the extent to which the Company enters into other
collaborative contractual arrangements, if any.
     Cost of sales increased to $19.7 million in 1996 from $10.7
million in 1995, due to the initiation of sales of RespiGam in
1996.  The gross margins for 1996 of 45% improved over 1995's
margins of 34% reflecting the addition of RespiGam as well as a
reduction in the royalty rate due to Connaught for CytoGam,
effective for the fourth quarter of 1995.  The Company's products
are manufactured by third parties and future per-unit cost of
sales could increase if the Company is unable to negotiate
favorable pricing.  The Company is currently constructing its own
manufacturing facility intended for some portion of the
production of its two approved products as well as other product
candidates.  This facility is not expected to be completed until
1998 and then is subject to inspection and approval by the FDA.
Cost of sales could be impacted by the potential production in
this facility.

<PAGE>34

     Research, development and clinical spending was $32.2
million in 1996 compared to $26.4 million in 1995, reflecting
increased expenditures of over $10 million for MEDI-493 RSV
Monoclonal Antibody clinical studies, including the start of a
1,502 patient Phase 3 clinical trial in the fourth quarter of
1996. This increase was offset by a decrease in clinical spending
for RespiGam, for which two Phase 3 trials were completed in mid-
1995 and licensing was received from the FDA in January 1996.
The level of the Company's total research and development
expenses in future periods will fluctuate depending on the extent
of clinical trial spending.  The Company expects clinical trial
expenses for MEDI-493 to remain high through the first half of
1997.
     Selling, administrative and general expenses increased to
$22.2 million in 1996 from $11.7 million in 1995, reflecting
primarily the launch of RespiGam in 1996.  Approximately 45
additional sales and marketing personnel have been hired since
September 30, 1995, primarily in 1996, to staff for the launch of
RespiGam, resulting in an increase of over $5 million in
salaries, commissions, recruiting, travel and related costs.  An
additional $5.2 million was spent on marketing and selling
programs for the launch of RespiGam in 1996.  Sales detailing
costs to the Company's corporate partner for RespiGam, AHP,
approximated $1.8 million in 1996 and none in 1995.  Offsetting
the increased costs in 1996 was a $4.3 million reimbursement from
AHP of their share of the product line loss on RespiGam for the
year, calculated under the terms of the strategic alliance.  In
1997 and future years, AHP's share of RespiGam's potential
profits will result in an increase to selling expenses. General
and administrative expenses increased by $0.7 million reflecting
increased headcount and legal and other costs associated with the
new manufacturing facility.
     In December 1995, the Company and Connaught entered into an
amendment to the agreement signed in 1992 in which the Company
reacquired the rights to market CytoGam.  In connection with this
amendment, the Company made a lump sum payment of $2.7 million to

<PAGE>35

Connaught in the first half of 1996 upon completion of certain
modifications to Connaught's filling and packaging facility.  The
$2.7 million charge was expensed as other operating expenses in
1995.
     Interest income increased to $5.7 million in 1996 compared
to $1.7 million in 1995.  The increase reflects the proceeds from
the Company's equity and convertible debt offerings in 1996,
resulting in higher cash balances available for investment,
partially offset by a decrease in interest rates which lowered
the overall portfolio yield.
     Interest expense increased to $2.3 million in 1996 from $0.3
million in 1995, reflecting interest on the convertible
subordinated notes issued in July 1996.  Interest expense in 1996
is net of $0.3 million of interest capitalized against the new
manufacturing facility and the pilot plant expansion.
     The 1996 net loss of $29.5 million, or $1.41 per common
share, compared to a 1995 net loss of $22.7 million, or $1.41 per
common share.  Shares used in computing loss per share were 21.0
million and 16.1 million, respectively. The Company does not
believe that inflation had a material effect on its financial
statements.
     These results were consistent with the Company's objectives
for the year and with the continued development of its
immunotherapeutic and vaccine products.  The factors affecting
1996 results may continue to affect near-term financial results.
     1995 COMPARED TO 1994
     Revenues in 1995 were $27.4 million compared to $18.9
million in 1994. Sales of CytoGam increased to $16.2 million in
1995 from $12.1 million in 1994, reflecting a 23% increase in
units sold as well as the impact of two price increases since
July 1, 1994.  Contract revenues increased to $11.3 million from
$6.8 million in 1994, primarily reflecting funding provided under
the Company's strategic alliance with AHP.
     Cost of sales for CytoGam rose to $10.7 million in 1995 from
$7.7 million in 1994, reflecting the increase in unit volume and

<PAGE>36

an increase in product unit costs, which include the addition of
a viral inactivation process, increased unit costs of plasma
paste and increased costs for finished product acquired from a
supplier.  Research, development and clinical spending was $26.4
million in 1995 compared to $21.9 million in 1994, reflecting a
research license payment of $2.0 million to BioTransplant,
Incorporated ("BTI") for BTI-322, and increased expenditures for
RespiGam and MEDI-493 RSV Monoclonal Antibody clinical studies.
Selling, administrative and general expenses increased to $11.7
million in 1995 from $9.2 million in 1994, reflecting increased
marketing expenditures for RespiGam, a $0.6 million charge
recorded in the fourth quarter in connection with the settlement
of the securities class action lawsuit that had been filed
against the Company, and a $0.5 million charge recorded in the
fourth quarter relating to certain expenditures associated with
preparations for the construction of a manufacturing facility.
     In December 1995, the Company entered into a Stipulation of
Settlement resolving a pending securities class action lawsuit
against the Company.  The Company recorded a charge of
approximately $0.6 million in 1995 in connection with the
settlement.  The Company's insurers contributed the remaining
$3.6 million in 1996, for a total settlement of $4.25 million.
     Other operating expenses include the charge for
restructuring of the Connaught agreement as discussed above.
     Interest income of $1.7 million was earned in the year ended
December 31, 1995 compared to $1.4 million in 1994, reflecting an
increase in interest rates which improved overall portfolio
yield.  Interest expense of $0.3 million was incurred in both
1995 and 1994.
     The 1995 net loss of $22.7 million, or $1.41 per common
share, compared to a 1994 net loss of $18.8 million, or $1.29 per
common share.  Shares used in computing loss per share were 16.1
million and 14.6 million, respectively.

     LIQUIDITY AND CAPITAL RESOURCES

<PAGE>37

     Cash and marketable securities were $114.8 million at 1996
year end compared to $38.0 million at 1995 year end. Working
capital was $113.3 million at 1996 year end versus $38.0 million
at 1995 year end.
     Net cash used in 1996 operating activities was $25.5 million
compared to $15.9 million used in 1995 and $20.3 million used in
1994.  The cash outflow from operations in 1996 reflected the net
loss adjusted for depreciation and amortization and working
capital changes.  Working capital changes include: 1) a $7.1
million increase in trade and contract receivables due to
significant fourth quarter sales of RespiGam; 2) a $5.6 million
increase in accounts payable and accrued expenses, reflecting
accrued costs associated with the MEDI-493 Phase 3 clinical
trial, accrued manufacturing costs for production of the
Company's two products, and accrued marketing and selling costs,
including commissions; and 3) a $2.1 million increase in accrued
interest reflecting interest due on the convertible subordinated
notes, paid January 1997.  The cash outflow from operations in
1995 reflected the net loss adjusted for depreciation and
amortization and working capital changes, including a $1.9
million decrease in trade and contract receivables and a $2.2
million increase in accrued expenses primarily related to the
amendment to the Connaught agreement.
     Cash flows from financing activities were $125.4 million in
1996 compared to $32.2 million in 1995.  In February 1996, the
Company completed a public offering of 3.45 million shares of
common stock resulting in net proceeds of $58 million and in July
1996, the Company completed a private placement of $60 million
aggregate principal amount of 7% convertible subordinated notes
due 2003 for net proceeds of $58 million.  Additionally, the
Company received $9 million of proceeds from state government
loans in connection with the financing of its new manufacturing
facility.  In 1995, the Company received $7.7 million from a
private placement of the Company's common stock with a group of
foreign institutional investors, $9.5 million from a sale of the
Company's common stock to Baxter in connection with an alliance
<PAGE>38
entered into in June 1995, and $15.0 million through a sale of
the Company's common stock to AHP.
     Capital expenditures in 1996 were $22.7 million compared to
$1.1 million in 1995.  The 1996 expenditures include $17.5
million for the design and construction of the Company's new
manufacturing facility located in Frederick, Maryland and the
expansion of the pilot plant at the Gaithersburg headquarters.
Additional expenditures were for land, laboratory equipment and
administrative expansion.  The 1995 expenditures included
expenditures for additional laboratory and office equipment as
well as initial design work for the new manufacturing facility.
     Capital expenditures in 1997 are expected to approximate $34
million, due mostly to the construction of the manufacturing
facility and the expansion of the development pilot plant.  These
two projects are anticipated to cost a total of $56 million and
are intended to be financed from the proceeds of the convertible
debt offering and state and local loans totaling $11.8 million.
The Company entered into an engineering, procurement,
construction and validation services agreement with Fluor Daniel
to design and construct the manufacturing facility in Frederick,
Maryland.  The agreement provides for an early completion bonus
to Fluor Daniel if the facility is completed ahead of schedule or
liquidated damages paid to the Company for certain delays.  The
facility, expected to employ 50 to 100 people, will provide
capacity for the Company's immune globulin products and
monoclonal antibody product candidates.  The facility is expected
to be completed and initial production commenced during 1998.
There can be no assurance that when the facility is constructed
appropriate regulatory approvals will be obtained to enable the
use of the facility for production of the Company's products or
product candidates.  The Company's pilot plant expansion is
intended to support the further production of materials for Phase
3 clinical trials and market entry requirements, if needed, for
MEDI-493.
     In addition, the Company is obligated in 1997 to provide
$14.5 million in funding for various clinical trials, research
<PAGE>39
and development and license agreements with certain institutions.
The Company's existing funds, together with funds contemplated to
be generated from product sales and investment income are
expected to provide sufficient liquidity to meet the anticipated
needs of the business for at least the next 18 months, absent the
occurrence of any unforeseen events.

                  NOTES TO FINANCIAL STATEMENTS
         (in thousands, except share and per share data)
                                
1.  ORGANIZATION
MedImmune, Inc. (the Company), a Delaware corporation, is a
biotechnology company focused on the development and marketing of
products for the prevention and treatment of infectious diseases
and for use in transplantation medicine.  The Company was
originally incorporated on June 29, 1987 and commenced operations
on April 22, 1988.
                                
2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Significant accounting policies applied in the preparation
of these financial statements are as follows:
                                
                                
                                
<PAGE>47
                               
Cash and Cash Equivalents
    The Company considers all highly liquid instruments
purchased with an original maturity of three months or less to be
cash equivalents.

Marketable Securities
     Marketable securities include investments with original
maturities of greater than three months having a remaining
maturity of less than 24 months.  The Company's securities are
held for an unspecified period of time and may be sold to meet
liquidity needs.  The securities included as marketable
securities are considered available-for-sale as defined by
Statement of Financial Accounting Standards No. 115, "Accounting
for Certain Investments in Debt and Equity Securities".
Amortized cost of marketable securities approximates market;
therefore, no adjustment has been made to shareholders' equity as
a result of changes in market value to these securities.
Interest income is accrued as earned.

Concentration of Credit Risk
     The Company has invested its excess cash generally in
securities of the U.S. Treasury, U.S. government agencies,
corporate debt securities, commercial paper and money market
funds with strong credit ratings and deposits with a major bank.
The Company has not experienced any significant losses on its
investments.  The Company sells its products primarily to a
limited number of pharmaceutical wholesalers without requiring
collateral.  The Company periodically assesses the financial
strength of these wholesalers and establishes allowances for
anticipated losses when necessary.

Inventory
     Inventory is stated at the lower of cost or market.  Cost is

<PAGE>48
determined using a weighted-average approach which approximates
the first-in, first-out method.  The Company receives revenues
from sales of a by-product that results from production of the
Company's principal products.  These sales are accounted for as a
reduction in the cost of the principal products.

Product Sales
     Product sales are recognized upon shipment of the product to
wholesalers.  Product sales are recorded net of reserves for
estimated chargebacks, returns, discounts, and Medicaid rebates.
The Company maintains reserves at a level which management
believes is sufficient to cover estimated future requirements.
Allowances for discounts, returns, bad debts, chargebacks and
Medicaid rebates, which are netted against accounts receivable,
totaled $2,170 and $330 at December 31, 1996 and 1995,
respectively.  Product royalty expense is recognized concurrently
with the recognition of product revenue. Royalty expense,
included in cost of sales, was $4,282, $3,056 and $2,416 for the
years ended December 31, 1996, 1995 and 1994, respectively.
                        
Contract Revenues
     Contract revenues are recognized over the fixed term of the
contract or, where appropriate, as the related expenses are
incurred.  Non-refundable fees or milestone payments in
connection with research and development or commercialization
agreements are recognized when they are earned in accordance with
the applicable performance requirements and contractual terms.
Payments received that are related to future performance are
deferred and recorded as revenues as they are earned over
specified future performance periods.
                                                                
<PAGE>49
Property and Equipment
     Property and equipment are stated at cost.  Depreciation of
laboratory and computer equipment is computed on the straight-
line method based upon estimated useful lives ranging from 3 to 7
years. Amortization of leasehold improvements is computed on the
straight-line method based on the shorter of the estimated useful
life of the improvement or the term of the lease.  Upon the
disposition of assets, the costs and related accumulated
depreciation are removed from the accounts and any resulting gain
or loss is included in the statements of operations.  Repairs and
maintenance costs are expensed as incurred and were $537, $540
and $350 for the years ended December 31, 1996, 1995 and 1994,
respectively.

Lease Expense
    Expense related to the facility lease is recognized on a
straight-line basis over the lease term.  The difference between
rent expense incurred and the amount of rent paid is recorded as
deferred rent and is included in other liabilities on the balance
sheet.

Income Taxes
    Deferred income taxes are recognized for the tax
consequences in future years of differences between the tax bases
of assets and liabilities and their financial reporting amounts
at each year end based on enacted tax laws and statutory tax
rates applicable to the periods in which the differences are
expected to affect taxable income.  Valuation allowances are
established when necessary to reduce deferred tax assets to the
amount expected to be realized.  Income tax expense is the tax
payable for the period and the change during the period in
deferred tax assets and liabilities.
                                
<PAGE>50
Earnings (Loss) Per Common Share
    Earnings (loss) per common share has been computed by
dividing net earnings (loss) by the weighted average number of
common shares and equivalents outstanding.  Common share
equivalents, representing shares issuable upon assumed exercise
of stock options and warrants and conversion of debt, are
included in the computation in periods where there are earnings
and when common share equivalents would have a dilutive effect.
Common share equivalents are not included in the computation in
periods with a loss because they are antidilutive.

Use of Estimates
    The preparation of financial statements in conformity with
generally accepted accounting principles requires management to
make estimates and assumptions that affect the amounts reported
in the financial statements and accompanying notes.  Actual
results could differ from those estimates.
                                
3.  INVENTORY

5.  FACILITIES LEASES
      The  Company  entered  into a 15-year  lease  beginning  in
November  1991,  as amended in 1993 and 1996, for  administrative
and  laboratory facilities in Gaithersburg, Maryland.  Under  the

<PAGE>52

lease, the Company is obligated to pay a basic monthly rent which
will  increase 3% each lease year and in 1996 totaled $855.   The
lease  also  requires the Company to pay for  utilities  and  its
proportionate   share  of  taxes,  assessments,   insurance   and
maintenance costs.  Rent expense for the years ended December 31,
1996, 1995 and 1994 was $1,113, $946 and $882, respectively.  The
1995  and  1994 expenses are net of sublease rental  receipts  of
approximately  $140  per  year from an affiliated  company.   The
sublease agreement was terminated in October 1995.

      The  Company's  future  minimum lease  payments  under  the

      The convertible subordinated notes were issued in July 1996
and  are  convertible at the option of the holder into  3,038,780
shares  of  the Company's common stock at a conversion  price  of
$19.68 per share, subject to adjustments in certain events.   The
notes  are not redeemable by the Company prior to July  7,  1999.
After that date, the notes are redeemable with 30 days notice  at
a  declining  premium until the due date, plus accrued  interest.
The  notes  are subordinated to all senior debts of  the  Company
including  the  state loans and the loans from the landlord.  The

<PAGE>54

Company may be required to redeem the notes at amounts up to 107%
of  the  principal amount in the event of a change in control  of
the Company.
      Principal and interest payments on the state notes begin in
1998.   Pursuant to the terms of the agreements, the  Company  is
required  to  meet certain financial and non-financial  covenants
including maintaining minimum cash balances and net worth ratios.
Cash  and  cash equivalents at December 31, 1996 include  a  $400
compensating  balance  related  to  the  notes.   The  notes  are
collateralized  by the land, buildings and building  fixtures  of
the new manufacturing facility.  Additional loans of $2.8 million
are  also  available  and  will be  drawn  down  in  1997.    The
agreements include a provision for early retirement of the  notes
by the Company.
      Maturities of long term debt for the next five years are as
follows: 1997, $118; 1998, $508; 1999, $678; 2000, $731 and 2001,
$789.  Interest paid was $304, $250 and $256, for the years ended
December  31, 1996, 1995 and 1994, respectively.  The fair  value
of  the  Company's long term debt at December 31, 1996, based  on
quoted  market prices or discounted cash flows based on currently
available  borrowing rates, was $74,040 compared to its  carrying
value of $70,992.

7.  EQUITY TRANSACTIONS
      In August 1996, the shareholders of the Company approved an
increase in the authorized number of shares of common stock  from
30 million shares to 60 million shares.
      The  holders  of  the Series A Convertible Preferred  Stock
warrants agreed that if such warrants are exercised, the  holders
thereof  will simultaneously exercise their right to convert  the

<PAGE>55

Series  A  Convertible Preferred Stock received upon exercise  of
the   warrants  into  2,524,525  shares  of  common  stock.   The
warrants,  which expire on January 12, 2000, are  exercisable  at
$1.00  per  share.   Pursuant  to an  amendment  to  the  warrant
agreement,  the  holders  may elect a cashless  exercise  of  the
warrants  for  a  reduced  number of common  shares  based  on  a
calculation of the fair market value of the common stock  on  the
exercise  date. During 1996, 415,873 of the Series A  Convertible
Preferred  Stock warrants were exercised and converted through  a
cashless  exercise  into 392,142 shares of common  stock.  As  of
December  31, 1996, the Company has reserved 2,108,652 shares  of
common  stock  for  issuance  upon conversion  of  the  Series  A
Convertible Preferred Stock.  The holders of common stock  issued
upon  conversion of the Convertible Preferred Stock have, subject
to certain limitations, piggyback and demand registration rights.

8.  Common Stock Options
    In April 1991, the Board of Directors adopted the 1991
Plan, amended in March 1992 and March 1995, under which 3,500,000
shares  of common stock were reserved for issuance upon  exercise
of  options granted to employees, consultants and advisors of the
Company.  In May 1993, a Non-Employee Directors Stock Option Plan
was  approved by the shareholders under which 250,000  shares  of
common  stock were reserved for issuance upon exercise of options
granted  to  non-employee directors.  The 1991 Plan provides  for
the grant of incentive and nonqualified stock options and the Non-
Employee  Directors Plan provides for the grant  of  nonqualified
stock  options.  Both Plans are administered by the  Compensation
and  Stock Committee of the Board of Directors. The maximum  term
of each option granted is 10 years.  The option

<PAGE>56

prices  under  the 1991 Plan and the Non-Employee Directors  Plan
are  equal  to the closing market price on the day prior  to  the
date of grant.
      Prior  to  the establishment of these plans, the  Board  of
Directors  granted  options and periodically set  option  prices.
The  Board of Directors established option prices, prior  to  the
Company's initial public offering on May 8, 1991, based  upon  an
evaluation  of  the  fair market value of  the  Company's  stock.
Options normally vest on the anniversary date of the grant over a
three  to five year period.  The Company has reserved a total  of
4,237,730  shares of common stock for issuance under these  plans
as  of  December 31, 1996.  Related stock option activity  is  as
follows:

     In February 1994, the Board of Directors authorized a Stock
Option Exchange Program which offered participants in the 1991
Plan holding stock options with exercise prices of $15.00 or
higher the choice to exchange their existing stock options for a
lesser number of new stock options having an exercise price of
$11.75, the fair market value on the date of grant, and a term of
8 1/2 years.  As a result of the exchange program, 813,800

<PAGE>58

options shares were exchanged for 564,478 new option shares which
resulted in the net cancellation of 249,322 option shares.
     Total option grants outstanding for all plans as of
December 31, 1996 were 3,582,420.  There were 490,310 and 165,000
shares available for future option grants at December 31, 1996
under the 1991 Plan and the Non-Employee Directors Plan,
respectively.
     The Company has adopted the disclosure-only provisions of
Statement of Financial Accounting Standards No. 123 (SFAS 123) as
they pertain to financial statement recognition of compensation
expense attributable to option grants.  As such, no compensation
cost has been recognized on the Company's option plans.  If the
Company had elected to recognize compensation cost for the 1991
Plan and the Non-Employee Directors Plan consistent with SFAS
123, the Company's net loss and loss per share on a pro forma
basis would be:
                                           1996      1995
                                          -----     -----
      Net loss - as reported            $29,544   $22,671
      Net loss - pro forma              $31,246   $23,850
      Loss per share - as reported        $1.41     $1.41
      Loss per share - pro forma          $1.49     $1.48

The pro forma expense related to the stock options is recognized
over the vesting period, generally five years.  The fair value of
each option grant was estimated using the Black-Scholes option
pricing model with the following weighted average assumptions for
each year:

<PAGE>59



                                               1996      1995
                                              -----     -----

       Expected life of options - years           7         7

       Expected dividend yield                  N/A       N/A

The weighted average fair value of options granted during 1996
and 1995 was $12.63 and $6.02 respectively.

9.  Co-Development and Co-Promotion Agreements
     On November 8, 1993, the Company signed definitive
agreements with American Cyanamid Company to form an alliance in
the United States for the development and marketing of three
generations of products to prevent and treat respiratory
syncytial virus (RSV) and for the marketing of a new anti-
infective product, ZOSYN, developed by American Cyanamid.   The
parties agreed to co-promote and share profits or losses on the
Company's RSV product, RespiGam, which was licensed for marketing
by the United States Food and Drug Administration on January 18,
1996.  In 1994, AHP acquired American Cyanamid and in October
1995, AHP invested $15,000 in the Company through the purchase of
967,742 shares of common stock.  In connection with this
investment, the Company and AHP agreed to amend certain terms of
agreements entered into concurrently with the formation of their
1993 alliance.  Pursuant to these amendments, AHP's funding
obligations and co-promotion rights with respect to the second
generation RSV product being developed by the Company were
terminated, and the Company returned its right to co-promote
ZOSYN to AHP.  In addition, the Company's obligation to co-fund

<PAGE>60

and to co-promote an RSV vaccine being developed by AHP was
converted into the right to receive royalties on any sales of
this vaccine, and AHP was granted the right to receive royalties
on any sales of the Company's second generation RSV product
currently under development.  The obligations undertaken by AHP
in 1993 to fund certain costs related to RespiGam, to make
certain milestone payments, including $4.5 million upon licensure
by the FDA, and to co-promote RespiGam are unchanged.  The $4.5
million milestone payment was received and recorded as contract
revenue in 1996.  Revenue of $4,791, $10,744, and $6,173 earned
in 1996, 1995 and 1994, respectively, associated with these
agreements is included as contract revenue in the accompanying
statements of operations.  Additionally, $4,299 of reimbursement
for co-promotion activity has been netted against selling,
general and administrative expense for the year ended
December 31, 1996.

10.  Connaught Agreement
     In December 1995, the Company and Connaught amended the
agreement originally signed in 1992 under which the Company
reacquired the rights to market CytoGam.  The amendment provides
for a reduction in the royalty rate to be paid by the Company on
sales of CytoGam after September 30, 1995, and an agreement
pursuant to which Connaught will fill and package the Company's
immune globulin products through 1998.  In connection with this
amendment, the Company made a lump sum payment of $2.7 million in
1996 to Connaught upon completion of certain modifications to
Connaught's filling and packaging facility.  The $2.7 million
charge is included as other operating expense in the accompanying
statements of operations for the year ended December 31, 1995.

<PAGE>61

11.    INCOME TAXES
     The tax effects of the temporary differences giving rise to
the Company's deferred tax assets at December 31, are as follows:

                                                1996        1995
                                              ------       -----
     Net operating loss carryforwards       $ 35,562    $ 24,924
     Other                                     4,377       3,113
                                             -------      ------
                                              39,939      28,037
     Valuation allowance                     (39,939)    (28,037)
                                             -------      ------
          Net deferred taxes                $     --    $     --
                                            ========    ========

     Realization of net deferred tax assets at the balance sheet
date is dependent on future earnings which are uncertain.
Accordingly, a full valuation allowance was recorded against the
assets.
     As of December 31, 1996, the Company had net operating loss
carryforwards available for federal income tax reporting expiring
in years 2003 through 2011 amounting to $111.7 million.  In
addition, the Company has $2 million of general business credit
carryforwards expiring through 2011.
     The total regular tax net operating loss available of $111.7
million includes $19.6 million which, when realized, will not
affect financial statement income but will be recorded directly
to shareholders' equity.  The realization of net operating losses
may be limited by Internal Revenue Code, Section 382.

12.  COMMITMENTS AND CONTINGENCIES
     Research, Development and License Agreements
     Baxter Healthcare Corporation.  In June 1995 the Company
entered into an exclusive, royalty-bearing license agreement with
Baxter Healthcare Corporation ("Baxter") to commercialize
RespiGam outside North America.  Within its territory, Baxter
will be responsible for funding clinical and regulatory
activities and for manufacturing and marketing RespiGam.  Upon
the achievement of certain sales milestones, Baxter is obligated
to reimburse the Company for certain previously funded research
and development activities.  Concurrent with the execution of the
license agreement, Baxter also purchased 826,536 shares of common
stock for $9.5 million.
     BioTransplant, Incorporated.  In October 1995, the Company
and BioTransplant, Incorporated ("BTI") formed a strategic
alliance for the development of products to treat and prevent
organ transplant rejection.  The alliance is based upon the
development of products derived from BTI's anti-CD2 antibody BTI-
322, the Company's anti-T cell receptor antibody MEDI-500 and
future generations of products derived from these two molecules,
including, but not limited to, MEDI-507.  Pursuant to the
alliance, the Company received an exclusive worldwide license to
develop and commercialize BTI-322 and any products based on BTI-
322, with the exception of the use of BTI-322 in kits for
xenotransplantation or allotransplantation.  The Company has paid
BTI $4 million in license fees and research support through
December 31, 1996. The Company has assumed responsibility for
clinical testing and commercialization of any resulting products.

<PAGE>63

BTI will receive additional research support and milestone
payments which could total up to an additional $12 million, as
well as royalties on any sales of BTI-322, MEDI-500, MEDI-507 and
future generations of these products, if any.
     Other Agreements.  The Company has entered into research,
development and license agreements with various federal and
academic laboratories and other institutions to develop further
its products and technology and to perform clinical trials.
Under these agreements, the Company is obligated to provide
funding of approximately $14,530 and $406 in 1997 and 1998,
respectively.  The Company has also agreed to make milestone
payments in the aggregate amount of $3,020 on the occurrence of
certain events such as the granting by the FDA of a license for
product marketing in the United States for some of the product
candidates covered by these agreements.  In exchange for the
licensing rights for commercial development of proprietary
technology, the Company has agreed to pay royalties on sales
using such licensed technologies.

     Construction Agreements
     The Company entered into an engineering, procurement,
construction and validation services agreement with Fluor Daniel,
Inc. ("Fluor") in July 1996 to design and construct the Company's
manufacturing facility to be located on a 26 acre site in
Frederick, Maryland.  The $42.5 million contract price is being
paid over an 18 month period based on achievement of certain
milestones.  In addition, the contract provides for an early
completion bonus or liquidated damages if Fluor deviates from the
agreed upon schedule.  The facility will provide capacity for the
production of the Company's immune globulin products; cell

<PAGE>64

culture for other product candidates, including MEDI-493; filling
and packaging; warehousing; laboratories and administration.

     Manufacturing, Supply and Purchase Agreements
     The Company has entered into manufacturing, supply and
purchase agreements in order to provide production capability for
CytoGam and RespiGam, and to provide a supply of human plasma for
production of both products.  No assurances can be given that an
adequate supply of plasma will be available from the Company's
suppliers.  Human plasma for CytoGam and RespiGam is converted to
an intermediate raw material (Fraction II+III paste) under a
supply agreement.  This intermediate material is then supplied to
the manufacturer of the bulk product. The Company has an informal
arrangement with the bulk manufacturer for planned production
through June 1997 for $5,141, subject to production level
adjustments.  If the bulk manufacturer, which holds the sole
product and establishment licenses from the FDA for the
manufacture of CytoGam and RespiGam, is unable to satisfy the
Company's requirements for both products on a timely basis or is
prevented for any reason from manufacturing CytoGam and RespiGam,
the Company may be unable to secure an alternative manufacturer
without undue and materially adverse operational disruption and
increased cost.  The Company also has an agreement with Connaught
to fill and package the Company's immune globulin products
through 1998.

13.  PENSION PLAN
     The Company has a defined contribution 401(k) pension plan
available to all full time employees.  Employee contributions are
voluntary and are determined on an individual basis subject to

<PAGE>65

the maximum allowable under federal tax regulations. Participants
are always fully vested in their contributions.  There have been
no employer contributions under the plan.

Report of Independent Accountants
To the Board of Directors and Shareholders MedImmune, Inc.
     We have audited the accompanying balance sheets of
MedImmune, Inc. (the Company) as of December 31, 1996 and 1995,
and the related statements of operations, shareholders' equity
and cash flows and financial statement schedule for each of the
three years in the period ended December 31, 1996.  These
financial statements are the responsibility of the Company's
management.  Our responsibility is to express an opinion on these
financial statements and financial statement schedule based on
our audits.
     We conducted our audits in accordance with generally
accepted auditing standards.  Those standards require that we
plan and perform the audit to obtain reasonable assurance about
whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial
statements.  An audit also includes assessing the accounting
principles used and significant estimates made by management, as
well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our
opinion.
     In our opinion, the financial statements referred to above
present fairly, in all material respects, the financial position
of the Company as of December 31, 1996 and 1995, and the results
of its operations and its cash flows for each of the three years
in the period ended December 31, 1996 in conformity with
generally accepted accounting principles.  In addition, in our
opinion  the financial statement schedule referred to above, when

<PAGE>67

considered in relation to the basic financial statements taken as

Report of Management

     The management of the Company is responsible for the
preparation of the financial statements and related financial
information included in this annual report.  The statements were
prepared in conformity with generally accepted accounting
principles, and accordingly, include amounts that are based on
informed estimates and judgments.
     Management maintains a system of internal controls to
provide reasonable assurance that assets are safeguarded and that
transactions are properly authorized and accurately recorded.
The concept of reasonable assurance is based on the recognition
that there are inherent limitations in all systems of internal
accounting control and that the costs of such systems should not
exceed the benefits expected to be derived. The Company
continually reviews and modifies these systems, where
appropriate, to maintain such assurance.  The system of internal
controls includes careful selection, training and development of
operating and financial personnel, well defined organizational
responsibilities and communication of Company policies and
procedures throughout the organization.
     The selection of the Company's independent accountants,
Coopers & Lybrand L.L.P., has been approved by the Board of
Directors and ratified by the shareholders.  The Audit Committee
of the Board of Directors, composed solely of outside directors,
meets periodically with the Company's independent accountants and
management to review the financial statements and related
information and to confirm that they are properly discharging
their responsibilities.  In addition, the independent accountants
and the Company's legal counsel meet with the Audit Committee,
without the presence of management, to discuss their findings and

their observations on other relevant matters.  Recommendations
made by Coopers & Lybrand L.L.P. are considered and appropriate
action is taken to respond to these recommendations.
