                              Item 1.  Business

MedImmune ("the Company") is a biotechnology company focused on developing
and marketing products for the prevention and treatment of infectious disease
and for use in 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.

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 filed a Biologic License Application ("BLA") requesting marketing
clearance in the United States for a third product, Synagis (palivizumab,
formerly known as MEDI-493). Additionally, the Company has five products
undergoing clinical trials and a number of product candidates and
technologies in the pipeline.
                                  <PAGE 1>
Products on the Market.
RespiGam
RespiGam was cleared by the United States Food and Drug Administration
("FDA") for marketing in the United States in January 1996.  RespiGam is
indicated for the prevention of serious respiratory syncytial virus ("RSV")
disease in children under 24 months of age with a chronic 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 an intravenous specialty immune globulin purified from donor
plasma screened for 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 in the Northern Hemisphere.  Certain populations of
infants, children and adults are at increased risk for developing severe RSV
disease.  Of the more than 300,000 infants at risk, there are approximately
100,000 at extreme risk who are the most common end-users of RespiGam.  These
include severely premature infants (i.e., less than or equal to 32 weeks
gestation) and infants with BPD.

The Company directly markets RespiGam to 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
received marketing clearance for RespiGam in Canada during 1997., however as
of December 31 the Canadian Blood Agency has not yet notified the Company as
to whether RespiGam will be reimbursed by the agency.
                                  <PAGE 2>
During 1997, RespiGam sales were $45.0 million.  The majority of these sales
occurred in fourth quarter 1997 because of inherent seasonality of demand.
Sales in 1997 were limited by supply.

The Company is aware of one potential direct competitor to RespiGam, the
Company's own product candidate, Synagis.  Sales of Synagis, if and when
cleared for marketing by the FDA, would largely replace RespiGam sales.
Consequently, if and when Synagis is cleared for marketing, the Company may
be compelled to record a reserve against RespiGam inventory.  The magnitude
of this inventory reserve, if any, would be determined by a number of
factors, including but not limited to, the anticipated timing of Synagis
marketing clearance, the extent of RespiGam inventory on hand at that time,
the assessed market potential of Synagis and the assessed market potential of
RespiGam.

CytoGam
CytoGam is an intravenous specialty immune globulin product enriched in
antibodies against CMV and 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 has been shown
to reduce the incidence of severe CMV disease and opportunistic infections
associated with kidney transplantation.  CytoGam was cleared for marketing by
the FDA in 1991 and was initially sold through an exclusive distribution
agreement with Connaught Laboratories. 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 25% since 1993 to $20.3
million in 1997.
                                  <PAGE 3>
The Company continues to expand the opportunities for CytoGam outside the
United States.  During 1997, the Company received marketing clearance for
CytoGam in Canada, Mexico and Poland and product was sold by distributors in
Turkey, the Czech Republic, Poland and Canada and on a named-patient basis in
Japan, Australia, Trinidad and Bolivia.  The Company expects to submit over
the next 12 to 18 months new applications requesting marketing clearance in
certain European, Latin American and Middle Eastern countries.

The Company's orphan drug status expired in 1997 and there can be no
assurance that additional CMV intravenous specialty immune globulin products
will not be successfully commercialized by other companies.  The Company is
aware of one other CMV immune globulin in development by NABI, Inc.

Products In Development
Synagis
Synagis (palivizumab; formerly known as MEDI-493) is a humanized monoclonal
antibody which has been evaluated by the Company in a number of clinical
trials and currently is being reviewed by the FDA for the prevention of
serious RSV disease in certain high-risk infants (for description of RSV
disease, see "RespiGam" above). Synagis is administered by intramuscular
injection, while RespiGam is administered by the more complex and time-
consuming process of intravenous infusion. Consequently, the Company believes
that Synagis has the potential to enhance patient care, reduce costs
associated with drug administration and improve convenience for parents,
physicians and nurses, as compared with RespiGam.  Taken together, the
Company believes these benefits may provide the potential for Synagis to
reach a broader population of children than RespiGam.  While RespiGam is
primarily a hospital-based drug, the Company believes a significant portion
of expanded Synagis use
                                  <PAGE 4>
will occur in pediatricians' offices.

During 1997, the Company announced the preliminary results of a double-blind
placebo-controlled Phase 3 clinical trial ("IMpact-RSV") conducted at 139
medical centers in 1,502 high-risk infants and children in the United States,
Canada and the United Kingdom. Initial analysis of these results suggested
that Synagis reduced the incidence of RSV-associated hospitalizations by 55
percent (p=0.00004; Fisher's exact test). The study included infants and
children who were either less than six months of age with a history of
prematurity (i.e., less than or equal to 35 weeks gestation) or less than
twenty-four months of age with BPD. Patients received a dose of either 15
mg/kg of Synagis (n = 1002) or placebo (n = 500) by intramuscular injection
each month for up to five doses during the RSV season, November 1996 through
April 1997.  Patients were followed for one month after their last dose for
safety and efficacy endpoints.  Analyses were conducted using the all-
randomized patient population.  In the Company's preliminary analysis,
certain of the secondary endpoints also reached statistical significance,
including RSV hospital days, RSV ICU admissions and RSV hospital days with
increased supplemental oxygen.

The profile of adverse events and serious adverse events was similar between
the Synagis and placebo groups.  Likewise, fatalities were balanced between
the treatment and placebo groups (0.4 percent (4/1002) in the group that
received Synagis and 1.0 percent (5/500) in the group that received placebo).
The fatality rates observed were consistent with those expected in these
children as a result of their severe underlying disease, and none of the
fatalities was attributed by the investigators to Synagis.

Based on these results and earlier pre-clinical and clinical studies,
                                  <PAGE 5>
the Company submitted in fourth quarter 1997 a BLA to the FDA requesting
marketing clearance of Synagis.  This application was submitted with required
product manufacturing data from the Company's Gaithersburg, Maryland pilot
plant.  The pilot plant is subject to FDA inspection and approval. The
Company cannot market Synagis in the United States unless and until licensed
to do so by the FDA. There can be no assurance that the FDA will grant such
clearance.

During fourth quarter 1997, the Company executed strategic agreements with
Abbott Laboratories ("Abbott") and Boehringer Ingelheim Pharma KG ("BI"),
related to the potential commercialization of Synagis. In December, the
Company and Abbott formed an exclusive worldwide marketing alliance
consisting of two separate agreements: a distribution agreement outside the
United States and a threshold-based co-promotion agreement within the United
States.  Abbott is a global, diversified health care company with $11 billion
in sales in 130 countries and a strong presence in pediatrics.  Outside the
United States, Abbott's international division will have the exclusive right
to market and distribute Synagis if and when cleared for marketing by
regulatory authorities.  The Company and Abbott expect to submit regulatory
applications to Canadian and European authorities during 1998.  Under terms
of the agreement, MedImmune received a $15 million payment in December 1997,
would receive an additional $30 million if and when Synagis receives United
States and European marketing approvals and would receive an additional $15
million upon the achievement of certain sales levels by Abbott.  For sales
outside the United States, MedImmune would manufacture and sell Synagis to
Abbott at a price based on end-user sales.  Within the United States,
Abbott's Ross Products division will co-promote Synagis with the Company.
The Company will be credited with all U.S. sales and Abbott will receive a
commission on sales above pre-determined thresholds.  Each company is
                                  <PAGE 6>
responsible for its own selling expenses.

Additionally in December, the Company and BI, a world-leading manufacturer of
biopharmaceutical products for therapeutic use, signed an agreement to
supplement MedImmune's own production capacity for Synagis.  During 1998, the
Company and BI expect to file a supplement to the Company's BLA for
additional manufacturing capacity utilizing the BI facility in Biberach,
Germany.  Product manufactured at the BI facility will be required to launch
Synagis, if it is approved by regulatory authorities.

While the Company believes it has established a comprehensive development
program for Synagis and an extensive commercialization plan if cleared for
marketing, substantial risk remains: 1) no assurances can be given that the
FDA will grant Synagis marketing clearance based on the data supplied, 2) no
assurances can be given that such marketing clearance, if forthcoming, would
be granted in a timely manner, 3) no assurances can be given that BI will
successfully be able to manufacture Synagis with adequate production yields,
appropriate timeliness and lasting economic feasibility, 4) no assurances can
be given that the Company's pilot plant will be licensed by the FDA for the
manufacture of Synagis in a timely manner, 5) no assurances can be given that
the quantity of such product, if successfully manufactured, would be
appropriately matched to its demand if and when cleared for marketing, and 6)
no assurances can be given that Synagis, if cleared for marketing, would be
successfully sold in the markets targeted by the Company and Abbott.

Human Papillomavirus Vaccine
Human papillomaviruses ("HPVs") are responsible for the development of
genital warts and cervical cancer.  There are currently no vaccines to
                                  <PAGE 7>
prevent these common sexually transmitted diseases that affect 24 to 40
million men and women 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 three HPV vaccine candidates, MEDI-501 (HPV-11), MEDI-503
(HPV-16) and MEDI-504 (HPV-18), each are composed of the HPV 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 first demonstrated the
effectiveness of a VLP vaccine candidate using a dog model for papillomavirus
infection. These data, first published in "The Proceedings of the National
Academy of Sciences" in December 1995, provided the scientific rationale for
developing an analogous vaccine for humans.

The Company began a Phase 1 clinical trial with MEDI-501 in January 1997 to
evaluate its safety, tolerance, and immunogenicity.  Initial data from the
trial suggested that MEDI-501 was safe and immunogenic. The Company also
expects to file Investigational New Drug (IND) applications during 1998 to
request clearance to begin clinical trials with MEDI-504 and MEDI-503. The
Company believes two or more HPV types would be necessary for a vaccine
capable of broadly preventing HPV disease of the genital tract.

In December 1997, the Company announced a strategic alliance with
                                  <PAGE 8>
SmithKline Beecham ("SB") to develop and commercialize the Company's HPV
vaccines.  Under terms of the agreement, SB receives exclusive worldwide
rights to the Company's HPV vaccine technology and both companies will
collaborate on research and development activities.  In January 1998, the
Company received an up-front payment of $15 million and an equity investment
of $5.0 million.  Pursuant to the agreement, the Company will also receive
research funding beginning in 1998, potential developmental and sales
milestones, as well as royalties on any product sales.  Total funding and
payments to the Company could total over $85 million.

Under terms of the agreement, the Company will conduct Phase 1 and Phase 2
clinical trials, manufacture clinical material for those studies and receive
funding from SB for these activities.  SB is responsible for the final
development of the product, as well as regulatory, manufacturing, and
marketing activities.

MEDI-507
MEDI-507 is a humanized monoclonal antibody being developed by the Company in
collaboration with BioTransplant, Incorporated.  The companies believe this
molecule has unique properties which may make it useful in one or more
applications where modulating an immune response may be desirable.  These
applications may include treatment of graft-versus-host disease("GvHD"),
prevention of organ transplant rejection or in treating autoimmune diseases
such as psoriasis.  MEDI-507 was derived from a rat monoclonal antibody
called BTI-322.

Both MEDI-507 and BTI-322 bind specifically to the CD2 antigen receptor found
on T cells and natural killer (NK) cells. Laboratory studies have suggested
that BTI-322 and MEDI-507 primarily inhibit the response of T cells directed
at transplant antigens while subsequently allowing
                                  <PAGE 9>
immune cells to respond normally to other antigens.  The selectivity
and long lasting effects of this inhibition suggest that these molecules may
have potential utility in applications such as transplantation and autoimmune
diseases.

During 1997, the companies began the first human MEDI-507 clinical trial, a
Phase 1 open-label, dose-escalating, transplantation induction trial to
evaluate the safety and tolerance of MEDI-507 in patients receiving kidney
transplants. Also during late 1997, the Company submitted to the FDA two INDs
requesting clearance to begin a Phase 1/2 study evaluating MEDI-507 in GvHD
and to begin a Phase 1 study in psoriasis patients.

BTI-322 has been evaluated in over 60 patients in the United States and
Europe for its potential to prevent and treat organ graft rejection and GvHD.
BTI-322 was evaluated in a multi-center Phase 2 trial for treatment of acute
GvHD. Initial analysis of data from this trial suggested that BTI-322 was
well-tolerated.  The average grade of GvHD improved during treatment with BTI-
322 (p=0.0005), however many patients relapsed after treatment was stopped.
In addition, preliminary analyses of data from two Phase 1/2 clinical studies
were presented in August 1996 at the XVI International Congress of the
Transplantation Society in Barcelona, Spain.  BTI-322 in these studies also
appeared well-tolerated and showed initial promise in preventing and treating
kidney transplant rejection.  A Phase 1/2 clinical trial evaluating BTI-322
in the treatment of acute kidney rejection is underway at the Massachusetts
General Hospital under an IND application submitted to the FDA by
BioTransplant.  In initial studies, both MEDI-507 and BTI-322 appear to
possess similar biological properties.  The companies expect to replace
development of BTI-322 with that of MEDI-
                                  <PAGE 10>
507 because of the potentially improved immunogenicity of a humanized
antibody such as MEDI-507 compared with a murine antibody such as BTI-322.

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 GvHD and organ rejection remain serious medical
problems. GvHD is the most common complication of bone marrow or stem cell
transplantation.  Approximately 50 percent of bone marrow transplants result
in GvHD which occurs when immune cells of the foreign graft, i.e., the donor
bone marrow, initiate an inflammatory reaction against the tissues of the
recipient. Typically, the disease is treated with steroids although
approximately 50 percent of patients fail to respond to steroid therapy.
Patients who develop moderate or severe GvHD have over a 70 percent chance of
death despite diverse treatments.  Lack of understanding of the physiologic
mechanism of disease has been a major impediment to the development of more
effective treatments. Both T cells and natural killer (NK) cells may play a
role in development of GvHD.  MEDI-507 which specifically inhibits both types
of cells may provide certain advantages over current therapies.  The Company
is aware of a number of companies developing products to prevent and treat
GvHD.

Autoimmune diseases are of major medical importance worldwide and include
common afflictions like rheumatoid arthritis, multiple sclerosis, Crohn's
disease and psoriasis.  The Company is aware of a number of companies
developing products to treat psoriasis and other autoimmune diseases.

Lyme Disease Vaccine
Lyme disease is the most common insect-borne disease in the United States.
Virtually every state within the United States has reported cases of Lyme
disease, with an annual nationwide reported incidence of 16,455 new cases in
1996, a 41 percent 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 is developing a B. burgdorferi protein called decorin binding
protein ("DbpA") which initial animal studies suggest may provide protection
against B. burgdorferi infection.  Unlike antibodies to vaccines in
development by other companies, DbpA antibodies can be given to mice four
days after infections 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 that DbpA is the only
protein identified form B. burgdorferi to date for which this effect has been
demonstrated.  In addition, antibodies from animals immunized with DbpA
inhibited growth of many strains of the Lyme disease-causing bacteria not
inhibited by antibodies to another vaccine candidate in development by the
Company, including some species of Lyme bacteria commonly found outside the
United States.  These results suggest that DbpA may provide an improved Lyme
disease vaccine candidate or, alternately, a supplement to the vaccine
candidates currently in development.

The Company is aware of two companies, SmithKline Beecham and Pasteur Merieux
Connaught, that have submitted BLAs to the FDA for Lyme disease vaccines
based on a protein known as OspA.   The Company is also aware of at least one
other company developing a Lyme disease vaccine based
                                  <PAGE 12>

on a protein known as OspC.  The Company believes that given the clinical
success of OspA, it is likely that DbpA would need to be combined with OspA
to result in a vaccine that is acceptable to the marketplace.

Urinary Tract Infection Vaccine
UTIs are a significant medical problem and one of the most common disorders
prompting medical attention in otherwise healthy women and children. UTIs,
caused by the bacterium Escherichia coli (E. coli), result in 7-8 million
physician and hospital visits per year at a cost of greater than $1 billion.
It is estimated that by age 30, roughly 50 percent of women have had at least
one infection and 2-10 percent are affected by recurrent infections. Females
are generally more prone to UTIs simply because of their anatomy.  Recent
studies have shown that, on average, women who are 18-40 years old get 1-2
infections over a two year period.  Older adults are also at risk with the
incidence as high as 33 out of 100 people.

Currently, there are no vaccines to prevent UTIs.  Most infections can be
treated with antibiotics, however, recurrence is common and emerging
antibiotic resistant bacteria create an additional threat.  Earlier attempts
to use pili, the hair-like protein appendages on the surface of bacteria, as
vaccine targets were not successful in protecting against a broad range of
pathogenic bacteria, including E. coli, because of the variation in the major
component of the pili.  The identification of specific proteins, or
"adhesins", at the end of pili which facilitate the attachment of E. coli to
human tissue, provided a novel target for vaccine development. The Company's
vaccine strategy is based on blocking these adhesins, preventing the disease-
causing bacteria from binding and accumulating in the bladder.  The novel
                                  <PAGE 13>
target of the Company's vaccine candidate is the FimH adhesin.  FimH does not
vary widely among the different strains of E. coli which cause UTIs.  The
Company believes this is a requisite quality for development of a broadly
effective UTI vaccine.

During 1997, the Company published in the journal "Science" the results of
experiments which suggested that a FimH-based vaccine was able to prevent
UTIs in mice.  In these studies, mice vaccinated with the Company's FimH
vaccine showed a greater than 99 percent reduction of bladder bacteria
compared to control animals.  The effect persisted for 29 weeks, the entire
length of the study.  Additionally, FimH antibodies were able to block the
ability of a broad range (94 percent) of E. coli strains to bind to bladder
cells in vitro.

The Company and its collaborators are currently conducting animal and primate
vaccination studies and designing clinical 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
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 two 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.
                                  <PAGE 14>
The Company has established a research collaboration with St. Jude Children's
Research Hospital("St. Jude") to develop products for the prevention and
treatment of Streptococcus pneumoniae infection.  The Company has been
granted a worldwide exclusive license from the Rockefeller University to
commercialize product candidates developed from a novel set of genes
discovered by scientists at St. Jude, formerly at Rockefeller University.  In
addition, research efforts are underway by scientists at the Company and St.
Jude to identify novel conserved surface proteins for potential vaccine
applications.  During 1998, promising candidate proteins are expected to be
characterized further in a number of in vitro and in vivo models to determine
their potential as vaccine candidates.

MEDI-491, B19 Parvovirus Vaccine
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.  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
                                  <PAGE 15>
immunization programs to reduce the prevalence of this virus.

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:

Abbott Laboratories
In December 1997, the Company entered into two agreements with Abbott
Laboratories ("Abbott").  The first agreement calls for Abbott to co-promote
Synagis in the United States, if and when licensed for marketing
                                  <PAGE 18>
by the FDA.  The second agreement allows Abbott to distribute Synagis outside
the United States, if and when licensed for marketing by the appropriate
regulatory authorities.  Outside the U.S., the Company would manufacture and
sell Synagis to Abbott at a price based on end user sales and could receive
additional milestone payments based on meeting certain milestones and sales
thresholds.  In the U.S., Abbott would receive a percentage of net sales in
excess of annual sales thresholds. Each company is responsible for its own
selling expenses.

American Home Products Corporation
The Company's strategic alliance with American Home Products ("AHP") calls
for the two companies to co-develop and co-promote RespiGam.  The agreement
provided for AHP to fund a portion of the cost of the development of RespiGam
and potentially co-promote the product in the United States.  AHP shares in
the profits and losses of RespiGam in the U.S.  The alliance provides for the
Company to receive royalties on any sales of AHP's RSV vaccine product,
currently in Phase 2 clinical development and for AHP to receive royalties on
any sales of Synagis.

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.  Concurrent with the execution of the license
agreement, Baxter also purchased 826,536 shares of Common Stock for $9.5
million.  Following the results from the Company's Phase 3 clinical trial of
Synagis, sales of which, if cleared for marketing, are expected to
substantially replace RespiGam, Baxter terminated this agreement and returned
to the Company all rights to commercialize RespiGam outside North America.
Baxter has no rights to Synagis.
                                  <PAGE 19>

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 (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 $4.5  million in license fees and research support
through December 31, 1997.  The Company has assumed responsibility for
clinical testing and commercialization of any resulting products. BTI maywill
receive research support and milestone payments which could total up to an
additional $11.0    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 have collaborative research
efforts underway to develop vaccines for non-typeable Haemophilus influenzae
and Streptococcus pneumoniae.  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. 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
                                  <PAGE 20>
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 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, then a
division of the Massachusetts Department of Public Health ("The State Lab"),
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
$13.3 million in 1997, $11.8 million in 1996 and $5.8 million in 1995, for
royalties, process development and manufacturing.  MHRI has rights to receive
royalties on any future sales of Synagis, if and when approved by the FDA.
See Note 13 of Notes to Financial Statements.

SmithKline Beecham
In December 1997, the Company entered into a strategic alliance with
SmithKline Beecham PLC ("SB") to research, develop, manufacture and
commercialize therapeutic and prophylactic HPV vaccines.  In exchange for
exclusive worldwide rights to the Company's HPV technology, SB has agreed to
provide the Company with an up-front payment of $15 million, future funding
and potential developmental and sales milestones which together could total
over $85 million, as well as royalties on any product sales. Under the terms
of the agreement, the companies will collaborate on research and development
activities.  MedImmune will conduct Phase 1 and Phase 2 clinical trials and
manufacture clinical material for those studies.  SB is responsible for the
final development of the product, as
                                  <PAGE 21>
well as regulatory, manufacturing, and marketing activities.  In January
1998, the Company received the $15 million payment from SB and completed the
sale of 83,410 shares of common stock to SB resulting in net proceeds to the
Company of $5.0 million.

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) Scientists at St. JudeRockefeller University
for the discovery and commercialization of products to treat and prevent
Streptococcus pneumoniae. In addition, the Company has license agreements
with third parties foron CytoGam, RespiGam, Synagis and substantially all of
its other potential products. Under such license agreements the Company is
obligated to pay royalties on any sales of these products.

Marketing and Sales
The Company has developed a sales and marketing organization which it
believes is responsive to the increased importance of managed care and the
need of the healthcare industry to provide lower costs and higher quality
care.
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 sales
force (then consisting of 14 people) focused on 250 leading transplantation
hospitals. Sales outside the United States are made through regional
distributors.
                                  <PAGE 22>
The Company now has approximately 75 people devoted to sales and marketing of
the Company's two approved products.  Approximately 48 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.

The Company has established a collaboration with Abbott, through its Ross
Pediatrics Division, to co-promote Synagis in the U.S., if and when Synagis
is cleared for marketing by the FDA.  In addition, Abbott has been selected
as the Company's exclusive distributor of Synagis outside of the U.S., if and
when Synagis is cleared for marketing by the appropriate regulatory
authorities. There can be no assurance that such approvals will be granted,
or, if granted, that approvals will occur in a timely manner.  See Footnote
10 in the Notes to Financial Statements for additional information related to
the agreements with Abbott.

Manufacturing and Supply The Company has agreements with the State Lab and
MHRI pursuant to which the Company agreed to license certain technology from
the Commonwealth of Massachusetts and to collaborate on the development of
the technology.  The technology relates to the two products currently being
marketed by the Company, RespiGam and CytoGam.
     At the end of 1996, the Inspector General of the Commonwealth of
Massachusetts publicly issued a report alleging, among other things, that
certain present and former employees of the State Lab or MHRI were personally
receiving from MHRI, in violation of state law, a portion of the royalties
the Company was paying to MHRI on sales of RespiGam.  The report also alleged
that the terms of the agreements were unfair to the Commonwealth and,
accordingly, the Commonwealth now has the right to rescind the agreements
notwithstanding the fact that the parties had operated under those agreements
for over seven years.  The Inspector General has no enforcement powers.
     The Company regards the allegations of the Inspector General, as they
relate to the Company, to be without merit.  The Company has denied those
allegations and in early 1997 provided the Commonwealth with a detailed
rebuttal of the claims of the Inspector General pertaining to the Company.
     The Company has been engaged with representatives of the Commonwealth in
negotiations to settle the matter on a mutually satisfactory basis.  While
the Company believes that substantial progress has been made toward resolving
this matter in a manner generally acceptable to the Company (with no loss of
the Company's rights to technology and no interruption of operations under
the agreements, but with increased royalties), there can be no assurance that
a final resolution will, in fact, be achieved. If no settlement is reached,
the Company may be forced to litigate with the Commonwealth, and there can be
no assurance that the outcome of such a litigation would be favorable to the
Company.  An unfavorable outcome could have a material adverse effect on the
Company.
     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
entered into an agreement with V.I. Technologies, Inc. in 1997 to supply
additional Fraction II+III paste.

The State Lab processes the Fraction II+III paste into bulk product. The
                                  <PAGE 23>
Company has an informal arrangement with the State Lab for planned
production of bulk product for CytoGam and RespiGam. The State Lab 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 the State Lab, 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. Recently, the Company has
experienced product shortages which have limited product sales without
reducing sales and marketing costs.  See Footnote 13 in the Notes to
Financial Statements for additional information related to the agreements
with the State Lab.

In 1997, the Company entered into a manufacturing and supply agreement with
BI to provide supplemental production capability for Synagis, a humanized
monoclonal antibody product for which a BLA was submitted to the FDA in
December 1997.  BI must scale up production to a level not previously
attempted.  No assurance can be given that BI will successfully be able to
manufacture Synagis at these levels, nor that it can achieve adequate
production yield, produce product with appropriate timeliness, or at an
acceptable cost.  Product manufactured at the BI facility will be required to
launch Synagis, if and when it is licensed for marketing by regulatory
authorities.  During 1998, the Company is expected to file a supplemental
amendment to its BLA for Synagis for additional manufacturing capacity
utilizing the BI facility. Should BI be unable to supply Synagis to the
Company for any reason, there can be no assurance that the Company would be
able to secure an alternate manufacturer in a timely basis or without
increased
                                  <PAGE 24>
cost.  Nor can there be any assurances that the Company or BI will be
licensed by the appropriate regulatory authorities to manufacture or market
the product.

The Company entered into an agreement with Chiron Corporation ("Chiron") in
1997, in which Chiron will fill and package Synagis produced at the
Gaithersburg pilot plant and Frederick manufacturing plant.  The term of the
agreement is for three years or until such earlier time as the Company is
able to fulfill all of its own requirements.  Filling and packaging of
Synagis at Chiron is subject to FDA approval.

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 located on a 27
acre site in Frederick, Maryland. The Company has spent $49.0 million through
December 31, 1997 on construction of the facility.  The facility,
construction of which is substantially complete,  is a multi-use biologics
facility intended to provide production capability for the manufacture of
immune globulins and by-products from human plasma. In addition, the facility
contains a cell culture production area for the manufacture of protein-based
products, such as Synagis, MEDI-501 and MEDI-507, if and when they are
cleared for marketing by the FDA. There can be no assurance that the facility
will receive regulatory approval for its intended purposes.  This facility is
subject to inspection and approval by the FDA and any resulting sales of
product from this facility would not commence for at least the next 18
months.  The Company has no experience in commercial manufacturing.
Accordingly, even if the necessary approvals were obtained, the Company would
encounter new risks associated with commercial manufacturing, including
potential scale-up issues, cost overruns, product defects and environmental
problems.
                                  <PAGE 25>

Furthermore, there can be no assurance that the Company will be able to
manufacture products at a cost that is competitive with third party
manufacturing operations.

The Company produces materials for clinical trials in its pilot plant
facility in Gaithersburg, Maryland. Materials currently being used in
clinical trials for MEDI-501, MEDI-507, and MEDI-491 have been produced at
the Company's pilot plant.  The Company completed an expansion of the pilot
plant facility in 1997 to support the production of materials for Phase 3
clinical trials and market entry production requirements, principally for
Synagis. There can be no assurance that 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 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.
     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
could adversely affect the Company's freedom to make, have made, use or sell
such products or use certain processes for their
                                  <PAGE 26>
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.
     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, biologics, 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, if approved, that the product would
be successfully commercialized or maintained in the marketplace.
Non-compliance with applicable requirements could 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.
                                  <PAGE 27>
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 seven year marketing
exclusivity period. CytoGam and RespiGam have been designated as Orphan Drugs
for certain indications by the FDA. Accordingly, RespiGam has market
exclusivity for its currently licensed indication through January 17, 2003.
Marketing exclusivity for CytoGam's currently licensed indication expired in
1997.

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 that required for FDA approval, and no
                                  <PAGE 28>

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.  In the prevention of CMV disease, the
Company's CytoGam competes with several other products including other
antiviral drugs, standard immune globulin preparations and intravenous and
oral ganciclovir, marketed 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.

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
                                  <PAGE 29>
indicated for the treatment of RSV disease.  Additionally, the Company's
Synagis is currently under review by the FDA.  Synagis has been evaluated in
a Phase 3 clinical trial for its ability to prevent RSV disease in a
population of infants and children similar to that for which RespiGam is
indicated.  If Synagis were to be cleared for marketing in the United States,
the Company believes sales of RespiGam would be substantially adversely
affected.  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.

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

         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 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.
Because of the seasonal nature of RSV, limited sales, if any, are expected
during the second and third quarters, causing results to vary significantly
from quarter to quarter.

RESULTS OF OPERATIONS
     1997 Compared to 1996
     Product sales increased 82% for the year ended December 31, 1997, over
the year ended December 31, 1996, due to increased demand for RespiGam in the
first half of the product's second full season of sales, as well as a 10%
increase in CytoGam sales. RespiGam sales were $45.0 million in 1997 versus
$17.3 million in 1996, a 159% increase,
                                  <PAGE 35>
reflecting an increase in vials sold.  Supply constraints limited 1997 and
1996 sales.  CytoGam product sales increased to $20.3 million from $18.4
million in 1996 due primarily  to a 4% increase in units sold, and two price
increases that took effect in mid-1996 and mid-1997.  In 1996 CytoGam product
sales were reduced by a $0.7 million reserve for trade receivables due from a
pharmaceutical wholesaler that filed Chapter 11 bankruptcy in August 1996;
$0.1 million was recovered against this loss in 1997 as a result of a sale of
the receivables to a third party.  Although the Company markets directly to
hospitals and physicians, the Company sells its products through a limited
number of pharmaceutical wholesalers. 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.  The Company submitted a Biologic
License Application to the FDA in December 1997 requesting marketing
clearance for its second generation RSV product, Synagis.  Marketing
clearance has not yet been obtained and there can be no assurance that such
approval will be obtained.  The Company believes that if Synagis were
licensed for marketing, it would significantly adversely affect sales of
RespiGam.
     Other revenues increased to $15.7 million in 1997 from $5.3 million in
1996. Other revenues in 1997 reflect primarily fees paid by Abbott
Laboratories for the right to market and distribute the Company's second
generation RSV drug, Synagis, outside the U.S.  The Company is also entitled
to receive an additional $30.0 million from Abbott upon receipt of a
marketing approval in the U.S. and other major markets.  Sales of Synagis are
dependent upon marketing clearance from the FDA and other regulatory
authorities and there can be no assurance that such clearance will be
obtained. Other revenues in 1996 reflect 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 share in the profits or losses of RespiGam; reimbursements or
payments under this arrangement are deducted from or added to operating
expenses and
                                  <PAGE 36>
are included in selling, administrative and general expenses.  Subsequent to
December 31, 1997, the Company received $15 million from SmithKline Beecham
pursuant to an agreement signed in December 1997 to develop and commercialize
human papillomavirus vaccines for prevention of cervical cancer and genital
warts.  This payment will be included in 1998 other revenues along with
research funding that will be due the Company under the terms of the
alliance.  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 75% to $34.4 million in 1997 from $19.7 million
in 1996, due to a 68% increase in vials sold.  Gross margins in 1997 improved
to 47% versus 45% in 1996,  reflecting the increased sales of RespiGam in the
product mix, which has a lower royalty rate than CytoGam.  1997 margins were
adversely impacted by a charge for an estimate of additional royalties due to
Massachusetts Health Research Institute as part of a possible settlement of
an ongoing inquiry by the Inspector General of the Commonwealth of
Massachusetts.  (See Note 13 of Notes to Financial Statements.)  If settled
as presently contemplated, the increased royalty rate would continue to apply
to future sales of RespiGam.  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 has substantially
completed construction of its own manufacturing facility intended for some
portion of the production of its two approved products as well as other
product candidates, including Synagis.  This facility is subject to
inspection and approval by the FDA and any resulting sales of product from
this facility would not commence for at least the next 18 months.  If Synagis
is licensed for marketing by the FDA, the Company may book a reserve against
RespiGam inventory.  The magnitude of this reserve, if any, would be
determined by factors including, but not limited to, the timing of Synagis
approval, the extent of RespiGam inventory on hand at the time, the assessed
market potential of Synagis and the assessed market potential of RespiGam.
Additionally, if Synagis is licensed for marketing by the FDA, its margin may
differ significantly from those of the Company's existing products; however,
because Synagis has never been produced in
                                  <PAGE 37>
commercial quantities, the impact, if any, on margins is not known.
     Research, development and clinical costs of $40.7 million were incurred
in 1997 compared to $32.2 million in 1996, an increase of 26%. Expenditures
in 1997 and 1996 include approximately $14.5 million and $10 million,
respectively, for the clinical studies performed for Synagis, including a
1,502-patient Phase 3 clinical trial that began in the fourth quarter of 1996
and was substantially completed by the end of the 1997 second quarter.  1997
expenses also include $1.3 million in license fees relating to Synagis and
MEDI-507, a monoclonal antibody that inhibits T cell responses.  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 to be significantly lower in 1998 than 1997.
     Selling, administrative and general expenses increased to $31.7 million
in 1997 from $22.2 million in 1996.  The increase in 1997 reflects primarily
AHP's share of RespiGam's profits, which resulted in a charge of $3.0 million
to selling expenses as calculated under the terms of the strategic alliance.
This compared to $4.3 million in reimbursement from AHP in 1996 for its share
of RespiGam product line loss, as calculated under the terms of the strategic
alliance.  Other selling and marketing expenses increased by $1.7 million,
reflecting increased commission and product distribution costs resulting from
the increased product sales.  This was offset by a $1.1 million decrease in
sales detailing costs to AHP as a result of the Company's decision to not use
AHP's sales force to detail RespiGam in the 1997/1998 RSV season.  General
and administrative expenses increased by $0.6 million reflecting increased
headcount, legal and other costs.  Selling, administrative and general
expenses are expected to increase in 1998 as the Company prepares for the
potential market launch of Synagis, if and when licensed by the FDA.
     Expenses in 1997 include $11.5 million of other operating expenses,
which include the costs of start-up of the Frederick manufacturing facility
and scale-up of production of Synagis at the Gaithersburg pilot plant and at
a third-party manufacturer, Boehringer Ingelheim Pharma KG ("BI") in
Biberach, Germany.  The Company expects
                                  <PAGE 38>
to incur significant start-up and scale-up costs throughout 1998 and into
1999.
     Interest income decreased to $4.0 million in 1997 compared to $5.7
million in 1996.  The decrease reflects lower cash balances available for
investment, partially offset by an increase in interest rates that increased
the overall portfolio yield.
     Interest expense increased to $3.5 million in 1997 from $2.3 million in
1996, reflecting primarily interest on the convertible subordinated notes of
the Company issued in July 1996 (net of amounts capitalized) and interest on
equipment financing, primarily in the second half of 1997.  Interest expense
in 1997 and 1996 is net of $2.2 and $0.3 million, respectively, of interest
capitalized against the manufacturing facility and the pilot plant expansion.
     The 1997 net loss of $36.9 million, or $1.59 basic and diluted per
common share, compared to a 1996 net loss of $29.5 million, or $1.41 basic
and diluted per common share.  Shares used in computing basic and diluted
loss per share were 23.1 million and 21.0 million, respectively, in 1997 and
1996.  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 that affected 1997 results may continue to affect near-
term future financial results.

     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, was 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 that filed Chapter 11
bankruptcy in August 1996.
     Other revenue decreased to $5.3 million in 1996 from $11.3 million in
1995, reflecting the completion of milestone and research funding
                                  <PAGE 39>
payments under the Company's strategic alliance with AHP.
     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.
     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 Synagis 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.
     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
were hired between September 1995 and March 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 its
share of product line loss on RespiGam for the year, calculated under the
terms of the strategic alliance.  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 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.
                                  <PAGE 40>
     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 of the
Company 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 basic and diluted per
common share, compared to a 1995 net loss of $22.7 million, or $1.41 basic
and diluted per common share.  Shares used in computing basic and diluted
loss per share were 21.0 million and 16.1 million, respectively, for 1996 and
1995.


LIQUIDITY AND CAPITAL RESOURCES
     Cash and marketable securities were $50.3 million at 1997 year end
compared to $114.8 million at 1996 year end. Working capital was $56.6
million at 1997 year end versus $113.3 million at 1996 year end.
     Net cash used in 1997 operating activities was $47.745.5 million
compared to $25.85 million used in 1996 and $15.9 million used in 1995. The
cash outflow from operations in 1997 reflected the net loss of $36.9 million
adjusted for depreciation and amortization and working capital changes.
Working capital changes included:  1) a $25.2 million increase in inventory
reflecting build-up of CytoGam and RespiGam to support increased sales;  2) a
$6.5 million increase in trade receivables as a result of the increased
fourth quarter sales, primarily RespiGam; and 3) a $17.4 million increase in
accounts payable and accrued expenses reflecting primarily accruals for
plasma inventories, contract manufacturing activities, amounts due to AHP for
its share of RespiGam product line profit and increased sales
                                  <PAGE 41>

commission accruals.  Most of the working capital increase in 1997
resulted from growth in accounts receivable, reflecting a 117% increase in
product sales in the fourth quarter 1997 versus the fourth quarter 1996 and
growth in inventory in anticipation of  increased first quarter 1998 sales
compared to first quarter 1997.  Inventory growth was also impacted by an
increase in plasma collections in 1997 as more plasmapheresis centers were
added to increase the volume of collections.  If Synagis is licensed for
marketing by the FDA, the Company may book a reserve against RespiGam
inventory for obsolescence as Synagis is expected to substantially replace
RespiGam in the market. The amount and timing of such a reserve, if any,
would depend on factors including, but not limited to, the anticipated timing
of Synagis marketing clearance, the extent of RespiGam inventory on hand at
that time, the assessed market potential of Synagis and the assessed market
potential of RespiGam.
AAdditionally, inventory is expected to increase significantly in 1998 as the
Company purchases Synagis inventory from BI and collects materials for use in
its new manufacturing facility to begin producing inventory for the potential
launch of Synagis.
     The cash outflow from operations in 1996 reflected the net loss adjusted
for depreciation and amortization and working capital changes. Working
capital changes included: 1) a $7.1 million increase in trade and contract
receivables due to significant fourth quarter 1996 sales of RespiGam; 2) a
$5.6 million increase in accounts payable and accrued expenses, reflecting
accrued costs associated with the Synagis 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.
     Cash flows from financing activities were $20.9 million in 1997
                                  <PAGE 42>
compared to $125.4 million in 1996.  In 1997, the Company drew down $14.4
million of $15.0 million of available equipment financing.  In addition, the
Company received the remaining $2.8 million of financing available from the
state and local government to fund the construction of the manufacturing
plant.  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 in 1996, the Company received $9
million of proceeds from state and local government loans in connection with
the financing of its manufacturing facility.
     Capital expenditures in 1997 were $36.738.9 million compared to $22.47
million in 1996 excluding capitalized interest of $2.2 million and $0.3
million, respectively.  The 1997 expenditures include $33.237.5 million (net
of capitalized interest) for the construction, equipment and validation of
the Company's manufacturing facility and the completion of its pilot plant
expansion at the Gaithersburg headquarters.  Additional expenditures were for
laboratory and office equipment.  The 1996 expenditures included $16.95
million (net of capitalized interest) for the design and construction of the
Company's manufacturing facility and the expansion of the pilot plant.
Additional expenditures were for land, laboratory equipment and
administrative expansion.
     Capital expenditures in 1998 are expected to approximate $7.0 million,
due mostly to expansion of the administrative area at the Gaithersburg
headquarters and the Frederick manufacturing facility to provide additional
capacity for the Company's cell culture product candidates.  Construction of
the manufacturing facility is substantially completed and initial process
qualification will commence during 1998.  There can be no assurance that
appropriate regulatory approvals will be obtained to enable the use of the
facility for production of the Company's products or product candidates.  Any
resulting sales of product from this facility would not commence for at least
the next 18 months, subject to regulatory approvals. Further production
capacity may be required to support future sales of MedImmune's product
candidates.  The Company is evaluating its

                                  <PAGE 43>
alternatives, including, but not limited to, significant expansion of
its existing facilities.  At this time, the Company is unable to determine
the potential cost or likelihood of this project.
     Subsequent to December 31, 1997, the Company received $15 million from
SmithKline Beecham ("SB") pursuant to an agreement signed with them in
December 1997 to develop and commercialize human papillomavirus vaccines for
prevention of cervical cancer and genital warts.  This payment will be
included in 1998 other revenues along with research funding of approximately
$5 million that will be due the Company under the terms of the alliance.  In
addition, in January 1998, the Company completed the sale of 83,410 shares of
common stock to SB for net proceeds to the Company of $5.0 million.  Also Iin
January 1998, the Company completed a private placement of 1.7 million shares
of common stock to three institutional investors for net proceeds to the
Company of $66.3 million.
     The Company is obligated in 1998 to provide $2.5 million in
funding for various clinical trials, research 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.

Year 2000 Compliance
   The Company has conducted a review of its internal and external systems for
year 2000 compliance and believes that the cost of completing any necessary
modifications will not be material.  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 are correct in their assertions that the
software is Year 2000 compliant, 3)that the Company's estimate of the cost of
systems preparation for Year 2000 compliance will prove ultimately to be
accurate.

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
                                  <PAGE 52>
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 determined
using a weighted-average approach that approximates the first-in, first-out
method.  Where the Company has a firm contract for their puchase, by-products
that result from production of the Company's principal products are accounted
for as a reduction of 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 that 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 $3,037 and $2,053 at December 31, 1997 and 1996,
respectively.  Product royalty expense is recognized concurrently with the
recognition of product revenue. Royalty expense, included in cost of sales,
was $8,504, $4,282 and $3,056 for the years ended December 31, 1997, 1996 and
1995, 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
                                  <PAGE 53>
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.
     Property and Equipment
     Property and equipment are stated at cost.  Interest cost incurred
during the period of construction of plant and equipment is capitalized.
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 $1,002, $537 and $540
for the years ended December 31, 1997, 1996 and 1995, respectively.

     Long-Lived Assets
     The Company evaluates the recoverability of the carrying value of
property and equipment and intangible assets in accordance with the
provisions of SFAS No. 121, "Accounting for the Impairment of Long-Lived
Assets to be Disposed Of."  The Company considers historical performance and
anticipated future results in its evaluation of the potential impairment.
Accordingly, when the indicators of impairment are present, the Company
evaluates the carrying value of these assets in relation to the operating
performance of the business and future and undiscounted cash flows expected
to result from the use of these assets.  Impairment losses are recognized
when the sum of the expected future cash flows are less than the assets'
carrying value.
                                  <PAGE 54>
     Forward Exchange Contracts
     The Company is obligated to make certain payments to a foreign supplier
in its local currency.  To hedge the effect of fluctuating foreign currencies
in its financial statements, the Company may enter into foreign forward
exchange contracts.  Gains or losses associated with the forward contracts
are computed as the difference between the foreign currency contract amount
at the spot rate on the balance sheet date and the forward rate on the
contract date.  Unrealized gains or losses are deferred until the obligation
date and are then offset against the gains or losses on the foreign currency
transaction.  See Note 12 for information regarding the fair value of the
Company's foreign forward exchange contracts.
     Fair Value of Financial Instruments
     The carrying amount of financial instruments including cash and cash
equivalents, trade accounts and contracts receivable, other current assets,
accounts payable, and accrued expenses approximate fair value as of December
31, 1997 and 1996 due to the short maturities of these instruments.  See Note
7 for information regarding the fair value of the Company's long-term debt
and notes payable and Note 12 for information regarding the fair value of the
Company's foreign forward exchange contracts.
     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 55>
     Earnings (Loss) Per Common Share
     In 1997, the Company adopted SFAS No. 128, Earnings per Share.  Basic
earnings per share is computed by dividing the net loss available to common
shareholders by the weighted average number of common shares outstanding
during the period.  Diluted earnings per share is computed by dividing net
earnings available to common shareholders by the weighted average number of
common shares outstanding after giving effect to all dilutive potential
common shares that were outstanding during the period.  Potential common
shares are not included in the computation of diluted earnings per share if
they are antidilutive.  Net loss per share as reported was not adjusted for
potential common shares as they are antidilutive.  Net loss available to
common shareholders as reported was not adjusted.  Earnings per share for all
other periods presented conform to SFAS No. 128.
     New Accounting Standards
     The Financial Accounting Standards Board has issued two new standards
which become effective for reporting periods beginning after December 15,
1997.  SFAS No. 130, Reporting Comprehensive Income, requires additional
reporting with respect to certain changes in assets and liabilities that
previously were included in shareholders' equity. The Company will begin
complying with the reporting required by SFAS No. 130 in the first quarter of
1998.  SFAS No. 131, Disclosures about Segments of an Enterprise and Related
Information, requires financial and descriptive information with respect to
"operating segments" of an entity based on the way management disaggregates
the entity for making internal operating decisions.  The Company will begin
making the disclosures required by SFAS No. 131 with financial statements for
the period ending December 31, 1998.
     Use of Estimates
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make
                                  <PAGE 56>
estimates and assumptions that affect the reported amounts of assets and
liabilities, and disclosure of contingent assets and liabilities at the
financial statement date and the reported amounts of revenues and expenses
during the reporting period.  Actual results could differ from those
estimates.

3.  INVENTORY
     Inventory at December 31, is comprised of the following:
                                     1997     1996
                                   ------   ------

                                  $28,857   $6,060
                                =========    =====



     At December 31, 1997, raw materials for one of the Company's existing
products being collected for production at the Company's manufacturing plant
which has not been licensed by the FDA, are classified as non-current as they
are not expected to be consumed within the next year.  In addition, finished
goods at December 31, 1997 include by-products that result from the
production of the Company's principal products at one of its contract
manufacturers and are held for resale.  As of December 31, 1997To date, no
sales of these by-products have occurred.
                                    <PAGE 57>
     The Company submitted a Biologic License Application to the FDA in
December 1997 requesting marketing clearance for its second generation RSV
product, Synagis.  The Company believes that if Synagis were licensed for
marketing, it would largely replace sales of RespiGam.  Consequently, if and
when Synagis is cleared for marketing, the Company may be compelled to record
a reserve against RespiGam inventory.  The magnitude of this inventory
reserve, if any, would be determined by a number of factors, including but
not limited to, the anticipated timing of Synagis marketing clearance, the
extent of RespiGam inventory on hand at the time, the assessed market
potential of Synagis and the assessed market potential of RespiGam.

     The convertible subordinated notes were issued in July 1996 and are
convertible at the option of the holder into 3,048,780 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 and local loans, the Transamerica loans, and the loan from the
landlord. The 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 and local 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. The Company maintains a $400
compensating balance related to the notes which is included in the
accompanying balance sheets as of December 31, 1997 and 1996.  The notes are
collateralized by the land, buildings and building fixtures of the
manufacturing facility.  The agreements include a provision for early
retirement of the notes by the Company.
     Loans from Transamerica Business Credit Corporation issued in 1997 are
repayable over 6 years at rates ranging from 10.13% to 10.6%.  The
                                  <PAGE 61>
loans are collateralized by manufacturing, laboratory, and office equipment
of the Company.  The Company may borrow up to an additional $0.6 million
under this facility.  The agreements include a provision for early retirement
of the loans by the Company.
     Maturities of long term debt for the next five years are as follows:
1998, $2,286; 1999, $2,625; 2000, $2,878; 2001, $3,164; and 2002, $3,476.
Interest paid was $4,817, $304 and $250, for the years ended December 31,
1997, 1996 and 1995, respectively.
     The fair value of the Company's long term debt at December 31, 1997,
based on quoted market prices or discounted cash flows based on currently
available borrowing rates, was $153,253 compared to its carrying value of
$87,649.

87.  SHAREHOLDERS' EQUITY
      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.
     In connection with the closing of the Company's initial public offering
in 1991, the holders of the Series A Convertible Preferred Stock warrants
agreed that if such warrants were exercised, the holders thereof would
simultaneously exercise their right to convert the Series A Convertible
Preferred Stock received upon exercise of the warrants into 2,524,525 shares
of common stock. Pursuant to an amendment to the warrant agreement in which
the holders could 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, 2,108,652 and 415,873  of the Series A
Convertible Preferred Stock warrants were exercised and converted through a
cashless exercise into 1,993,353 and 392,142 shares of common stock in 1997
and 1996, respectively. As of December 31, 1997, all warrants were exercised
and converted.
                                  <PAGE 62>
     In July 1997, the Company's Board of Directors adopted a Stockholder
Rights Plan.  Pursuant to the terms of the Plan, common stock purchase Rights
were distributed as a dividend at the rate of one Right for each share of
common stock of the Company held by stockholders of record as of the close of
business on July 21, 1997.  The Rights will be exercisable only if a person
or group acquires beneficial ownership of 20 percent or more of the Company's
common stock or commences a tender or exchange offer upon consummation of
which such a person or group would beneficially own 20 percent or more of the
Company's stock. The Rights will expire on July 9, 2007.
     In January 1998, the Company closed the private placement of 1.7
million1,700,000 new shares of common stock to institutional investors for
net proceeds of $66.3 million., and sold 83,410 shares of common stock to
SmithKline Beecham for net proceeds of $5.0 million.

98.  COMMON STOCK OPTIONS
          In April 1991, the Board of Directors adopted the 1991 Plan,
amended in March 1992, March 1995 and February 1997, under which 5,500,000
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. The maximum term of each option granted is 10 years.  The option
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
                                  <PAGE 63>
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
5,623,101 shares of common stock for issuance under these plans as of
December 31, 1997.  Related stock option activity is as follows:

 There were 1,803,763 and 145,000 shares available for future option grants
at December 31, 1997 under the 1991 Plan and the Non-Employee Directors Plan,
respectively.
    The Company has adopted the disclosure-only provisions of SFAS No. 123 as
they pertain to financial statement recognition of compensation expense
attributable to option grants.  As such, no compensation cost has been
recognized for 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 No. 123, the Company's net loss and basic and
diluted loss per share on a pro forma basis would be:

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:

                                           1997        1996        1995

The weighted average fair value of options granted during 1997, 1996 and
19965 was $12.94and , $12.63 and $6.02, respectively.

10.  COLLABORATIVE ARRANGEMENTS
     American Home Products
     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
                                  <PAGE 66>
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 million 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 monoclonal
product developed by the Company were terminated, the Company returned its
right to co-promote ZOSYN to AHP and AHP received a right to receive a
royalty on any sales of the RSV monoclonal product.  In addition, the
Company's right to co-fund and to co-promote an RSV vaccine being developed
by AHP was converted into the right to receive royalties on any sales of the
vaccine.  Revenue of $4,791 and $10,744 in 1996 and 1995, respectively,
associated with these agreements is included as other revenue in the
accompanying statements of operations.  Additionally, $2,967 of expense and
$4,299 of reimbursement for co-promotion activity have been added to and
netted against selling, general and administrative expense for the years
ended December 31, 1997 and 1996, respectively.
     Abbott Laboratories
     In December 1997, the Company signed two agreements with Abbott
Laboratories ("Abbott").  The first agreement calls for Abbott to co-promote
Synagis in the U.S., if and when cleared for marketing by the FDA. The second
agreement allows Abbott to exclusively distribute Synagis outside the U.S.,
if and when cleared for marketing by the appropriate regulatory authorities.
Under the terms of the U.S. co-
                                  <PAGE 67>
promotion agreement, Abbott will receive a percentage of net U.S. sales
based on defined annual sales thresholds.  Each company is responsible for
its own selling expenses.  Under the terms of the distribution agreement, the
Company will manufacture and sell Synagis to Abbott at a price based on end
user sales.  The Company received a $15 million milestone payment as part of
this agreement in 1997, which is included in other revenue.  The Company
could receive up to an additional $45 million based on the achievement of
certain milestones, including U.S. and European marketing clearance of
Synagis.
     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 $4.5
million in license fees and research support through December 31, 1997.  The
Company has assumed responsibility for clinical testing and commercialization
of any resulting products.  BTI may receive additional research support and
milestone payments that could total up to an additional $11.0 million, as
well as royalties on any sales of BTI-322, MEDI-500, MEDI-507 and future
generations of these products, if any.
     Connaught Agreement
     In December 1995, the Company and Connaught amended the agreement
                                  <PAGE 68>
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.
     SmithKline Beecham
     In December 1997, the Company and SmithKline Beecham ("SB") entered into
a strategic alliance to develop and commercialize human papillomavirus (HPV)
vaccines for prevention of cervical cancer and genital warts.  In exchange
for exclusive worldwide rights to the Company's HPV technology, SB has agreed
to provide the Company with an up-front payment, future funding and potential
developmental and sales milestones which together could total over $85
million, as well as royalties on any product sales.  Under the terms of the
agreement, the companies will collaborate on research and development
activities.  MedImmune will conduct Phase 1 and Phase 2 clinical trials and
manufacture clinical material for those studies.  SB is responsible for the
final development of the product, as well as regulatory, manufacturing, and
marketing activities.  In January 1998, the Company received a $15 million
payment from SB and completed the sale of 83,410 shares of common stock to SB
resulting in net proceeds to the Company of $5.0 million.
     Other Agreements
                                  <PAGE 69>
   The Company has entered into research, development and license
agreements with various federal and academic laboratories and other
institutions to further develop its products and technology and to perform
clinical trials.  Under these agreements, the Company is obligated to provide
funding of approximately $2.5 million       and $0.8 million     in 1998 and
1999, respectively.  The Company has also agreed to make milestone payments
in the aggregate amount of $11.5 million       on the occurrence of certain
events such as the granting by the FDA of a license for product marketing in
the U.S. 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.

1110.  INCOME TAXES
     The tax effects of the temporary differences giving rise to the
Company's deferred tax assets at December 31, are as follows:

                                                1997        1996
                                              ------       -----
     Net operating loss carryforwards       $ 46,820    $ 35,562
     Other                                     8,426       4,377
                                             -------      ------
                                              55,246      39,939
     Valuation allowance                    (55,246)    (39,939)
                                             -------      ------
          Net deferred taxes                $     --    $     --
                                            ========    ========

     Realization of net deferred tax assets at the balance sheet date
                                  <PAGE 70>
is dependent on future earnings, which are uncertain.  Accordingly, a
full valuation allowance was recorded against the assets.  A reversal of the
valuation allowance will be considered when it is more likely than not that
the Company's deferred tax assets (comprised mostly of net operating loss
carryforwards and research credits) will be realized.
     As of December 31, 1997, the Company had net operating loss
carryforwards available for federal income tax reporting expiring in years
2003 through 2012, amounting to $158.6 million.  In addition, the Company has
$3.2 million of general business credit carryforwards expiring through 2012.
     The total regular tax net operating loss available of $158.6 million
includes $37.3 million that, 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.

121.  FORWARD EXCHANGE CONTRACTS
     Beginning in 1997, the Company entered into foreign forward exchange
contracts to hedge against foreign exchange rate fluctuations that may occur
on the Company's foreign currency denominated obligations. During 1997, the
Company entered into forward deutsche mark contracts in the amount of $21,535
, all expiring within one year. Through December 31, 1997, $2,495       of
these contracts have been paid, resulting in a remaining contract balance of
$19,040.  Fair value of the remaining balance at December 31, 1997 was
$18,625, resulting in an unrealized loss of $415.  Unrealized gains and
losses on foreign forward exchange forward contracts that
are designated and effective as hedges are deferred and recognized in
                                  <PAGE 71>
the same period that the hedged obligation is recognized.  The notional
principal amounts for off-balance sheet instruments provide one measure of
the transaction volume outstanding as of year end, and does not represent the
amount of the Company's exposure to credit or market loss.  The Company's
exposure to credit loss and market risk will vary over time as a function of
interest rates and currency rates.

132.  COMMITMENTS AND CONTINGENCIES
     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 located on a 27
acre site in Frederick, Maryland.  As of December 31, 1997, $42.4 million of
the $42.5 million contract has been paid. In addition, the Company is in
negotiations with Fluor to make payments in 1998 for additional expenditures
needed to complete the facility.  The facility will provide capacity for the
production of immune globulin products; cell culture for other product
candidates, including Synagis; filling and packaging; warehousing;
laboratories and administration.
     Manufacturing, Supply and Purchase Agreements
     In 1989 and 1990, the Company entered into a series of contracts with
the Massachusetts Public Health Biologic Laboratory, then a division of the
Massachusetts Department of Public Health (the "State Lab"), and the
Massachusetts Health Research Institute, Inc. ("MHRI") pursuant to which the
Company agreed to license certain technology from the Commonwealth of
Massachusetts and to collaborate on the development of the technology.  The
technology relates to the two products, RespiGam and CytoGam, currently being
marketed by the Company.
     At the end of 1996, the Inspector General of the Commonwealth of
                                  <PAGE 72>
Massachusetts publicly issued a report alleging, among other things, that
certain present and former employees of the State Lab or MHRI were personally
receiving from MHRI, in violation of state law, a portion of the royalties
the Company was paying to MHRI on sales of RespiGam.  The report also alleged
that the terms of the agreements were unfair to the Commonwealth and,
accordingly, the Commonwealth now has the right to rescind the agreements
notwithstanding the fact that the parties had operated under those agreements
for over seven years.  The Inspector General has no enforcement powers.
     The Company regards the allegations of the Inspector General, as they
relate to the Company, to be without merit.  The Company has denied those
allegations and in early 1997 provided the Commonwealth with a detailed
rebuttal of the claims of the Inspector General pertaining to the Company.
     The Company has been engaged with representatives of the Commonwealth in
negotiations to settle the matter on a mutually satisfactory basis.  While
the Company believes that substantial progress has been made toward resolving
this matter in a manner generally acceptable to the Company (with no loss of
the Company's rights to technology and no interruption of operations under
the agreements, but with increased royalties), there can be no assurance that
a final resolution will, in fact, be achieved. If no settlement is reached,
the Company may be forced to litigate with the Commonwealth, and there can be
no assurance that the outcome of such a litigation would be favorable to the
Company.  An unfavorable outcome could have a material adverse effect on the
Company.
     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
                                  <PAGE 73>
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 two supply agreements with two vendors.  This
intermediate material is then supplied to the manufacturer of the bulk
product, the State Lab. Pursuant to the agreements with the State Lab, the
Company paid $10.2 million in 1997, $9.7 million in 1996, and $5.2 million in
1995 for production and process development.  The Company has an informal
arrangement with the State Lab for planned production through June 1998 for
$7,820, subject to production level adjustments.  If the State Lab, 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.
     In December 1997, the Company entered into an agreement with Boehringer
Ingelheim Pharma KG, to provide supplemental manufacturing of the Company's
second generation RSV product, Synagis, for which a BLA was submitted to the
FDA in December 1997.  The Company expensed as other operating expenses
$5,403 in 1997 related to scale-up of production as part of this agreement.
The Company is obligated to pay approximately 34.2          million deutsche
marks, or about $19.4        million in 1998 for scale-up and market entry
quantities of Synagis.  There can be no assurances that should the
manufacturer be unable to supply Synagis to the Company for any reason, that
the Company will be able to secure an alternate manufacturer in a timely
basis or without increased cost. Nor can there be any assurances that the
Company or the supplemental
                                  <PAGE 74>
manufacturer will be licensed by the appropriate regulatory authorities
to manufacture or market the product.

14.  OTHER OPERATING EXPENSES
     Other operating expenses in 1997 include the costs of start-up of the
Frederick manufacturing facility and scale-up of production of Synagis at the
Gaithersburg pilot plant and at a third-party manufacturer, Boehringer
Ingelheim Pharma KG ("BI") in Biberach, Germany.  The Company expects to
incur significant start-up and scale-up costs throughout 1998 and into 1999.
     Other operating expenses in 1995 include charges to Connaught in
connection with an agreement to fill and package the Company's immune
globulin products.

135.  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 the maximum allowable under
federal tax regulations. Participants are always fully vested in their
contributions.  The Company began employer contributions as of April 1, 1997.
During 1997, the Company contributed $122 in cash to the plan.

Report of Independent Accountants
To the Board of Directors and Shareholders of MedImmune, Inc.
     We have audited the accompanying balance sheets of MedImmune, Inc. (the
Company) as of December 31, 1997 and 1996, 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, 1997.
These financial statements and the financial statement schedule 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, 1997 and 1996, and the results of its operations and its cash
flows for each of the three years in the period ended December 31, 1997 in
conformity with generally accepted accounting principles.  In addition, in
our opinion the financial statement schedule referred to above, when
considered in relation to the basic financial statements taken as a whole,
presents fairly, in all material respects, the information required to be
included therein.

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.

                                 (PAGE 6)
                              (iii)Calculation of NET SALES,

                              (iv) Total compensation payable to ABBOTT.

     (e)  Each PARTY shall keep complete and accurate records as are
     required to verify compliance with this Agreement.  Such records shall
     be retained and made available for reasonable review by an independent
     public accounting firm acceptable to both PARTIES upon reasonable
     notice, during normal business hours and no more than once each YEAR,
     and at the reviewing PARTY's expense, for the purposes of verifying
     the accuracy of the accounting.  Each document from which the reports
     and statements are prepared pursuant to this Agreement shall be
     retained for two (2) years, and the right of inspection and the right
     of audit hereunder shall terminate with respect thereto at the end of
     such two (2) year period.  In the event that such inspection shall
     indicate that in any calendar year that the payments which should have
     been paid by MEDIMMUNE are at least five percent (5%) greater than
     those which were actually paid by MEDIMMUNE, then MEDIMMUNE shall pay
     the cost of such inspection.  All underpayments are immediately due
     and payable.

2.6  (CONFIDENTIAL TREATMENT HAS BEEN REQUESTED)

2.7  Each PARTY shall promptly notify the other PARTY in writing of any
     facts relating to the advisability of the recall, destruction or
     withholding from the market of the PRODUCT anywhere in the world
     (collectively, "Recall").  If at any time (a) any governmental or
     regulatory authority in the TERRITORY issues a request, directive or
     order for a Recall; (b) a court of competent jurisdiction orders a
     Recall in the TERRITORY; or (c) MEDIMMUNE determines, following
     consultation with ABBOTT (except in emergency situations in which
     there is insufficient time for such consultation), that a Recall in
     the TERRITORY is necessary or advisable, MEDIMMUNE shall take all
     appropriate corrective actions, at MEDIMMUNE's expense, to effect the
     Recall and ABBOTT shall provide MEDIMMUNE with such cooperation in
     connection with the Recall as MEDIMMUNE may reasonably request.

3.   INDEMNITY

3.1  (a)  MEDIMMUNE shall defend, indemnify and hold harmless ABBOTT,
     AFFILIATES of ABBOTT and their respective directors, officers, agents
     and employees, from and against any and all liability, loss, damages
     and expenses (including attorneys' fees) as the result of THIRD PARTY
     claims, demands, costs or judgments which may be made or instituted
     against any of them arising out of (i) any negligent act or omission
     or willful misconduct of MEDIMMUNE, AFFILIATES of MEDIMMUNE or any of
     their respective officers, directors, agents or employees  with
     respect to PRODUCT, (ii) any violation of approved labeling or any
     applicable statute or regulation with respect to PRODUCT, or breach of
                                 (PAGE 7)
     this Agreement or any representation or warranty hereunder, by
     MEDIMMUNE, AFFILIATES of MEDIMMUNE or any of their respective
     officers, directors, agents or employees, (iii) the manufacture,
     possession, packaging, distribution (except for the distribution of
     PRODUCT samples by ABBOTT representatives), use, testing, sale or
     other disposition of the PRODUCT, or (iv) any claim against ABBOTT for
     patent or trademark infringement in connection with the manufacture,
     use or sale of the PRODUCT.   MEDIMMUNE shall not be obligated to
     indemnify an indemnified party to the extent that any claims against
     an indemnified party result from (i) any negligent act or omission or
     willful misconduct of ABBOTT, AFFILIATES of ABBOTT or any of their
     respective officers, directors, agents, or employees with respect to
     the PRODUCT, or (ii) any violation of approved labeling or any
     applicable statute or regulation with respect to PRODUCT (provided
     that ABBOTT shall not be deemed to be in violation of this provision
     by using promotional materials provided by MEDIMMUNE), or breach of
     this Agreement or any representation or warranty hereunder, by ABBOTT,
     AFFILIATES of ABBOTT or any of their respective officers, directors,
     agents, or employees with respect to the PRODUCT, or  (iii) marketing
     of the PRODUCT or any other action with respect to PRODUCT by ABBOTT,
     AFFILIATES of ABBOTT or any of their respective officers, directors,
     agents or employees, in each case which is not in compliance with
     applicable law, rules or regulation, (ABBOTT shall not be deemed to be
     in violation of this provision for using promotional materials
     provided by MEDIMMUNE) or (iv) any claim warranty or representation by
     ABBOTT, AFFILIATES of ABBOTT or any of their respective officers,
     directors, agents or employees with respect to PRODUCT which has not
     been approved in advance by MEDIMMUNE.  MEDIMMUNE shall have the
     exclusive right to control the defense of any action which is to be
     indemnified in whole by MEDIMMUNE hereunder, including the right to
     select counsel reasonably acceptable to ABBOTT to defend ABBOTT, and
     to settle any claim, provided that, without the written consent of
     ABBOTT (which shall not be unreasonably withheld or delayed),
     MEDIMMUNE shall not agree to settle any claim against ABBOTT.  The
     provisions of this paragraph shall survive and remain in full force
     and effect after any termination, expiration or cancellation of this
     Agreement and MEDIMMUNE'S obligation hereunder shall apply whether or
     not such claims are rightfully brought.

     (b)  ABBOTT shall defend, indemnify and hold harmless MEDIMMUNE,
     AFFILIATES of MEDIMMUNE,  and their respective directors, officers,
     agents and employees, from and against any and all liability, loss,
     damages and expenses (including attorneys' fees) as the result of
     THIRD PARTY claims, demands, costs or judgments which may be made or
     instituted against any of them arising out of (i) any negligent act or
     omission or willful misconduct of ABBOTT, AFFILIATES or ABBOTT or any
     of their respective officers, directors, agents or employees, with
     respect to the Product or (ii) any violation of approved labeling or
     any applicable statute or regulation with respect to PRODUCT (ABBOTT
                                 (PAGE 8)
     shall not be deemed to be in violation of this provision by using
     promotional material provided by MEDIMMUNE), or breach of this
     Agreement or any representation or warranty hereunder, by ABBOTT,
     AFFILIATES of ABBOTT or any of their respective officers, directors,
     agents or employees,  or (iii) the marketing  of the PRODUCT, or any
     other action of ABBOTT, AFFILIATES of ABBOTT or any of their
     respective officers, directors, agents or employees, with respect to
     PRODUCT in each case which is not in compliance with applicable law,
     rules or regulation (provided that ABBOTT shall not be deemed to be in
     violation of this provision by using promotional materials provided by
     MEDIMMUNE), or (iv) from any claim, warranty or representation of
     ABBOTT, AFFILIATES of ABBOTT or any of their respective officers,
     directors, agents or employees, with respect to PRODUCT which has not
     been approved in  advance by MEDIMMUNE.  ABBOTT shall not be obligated
     to indemnify an indemnified party to the extent that any claims
     against an indemnified party result from (i) any negligent act or
     omission or willful misconduct of MEDIMMUNE, or Affiliates of
     MEDIMMUNE  or any of their respective officers, directors, agents or
     employees with respect to the PRODUCT, (ii) any violation of approved
     labeling or any applicable statute or regulation with respect to
     PRODUCT, or breach of this Agreement or any representation or warranty
     hereunder, by MEDIMMUNE, AFFILIATES of MEDIMMUNE or any of their
     respective officers, directors, agents or employees, (iii) the
     manufacture, possession, packaging, distribution (except for the
     distribution of PRODUCT samples by ABBOTT representatives), use,
     testing, sale or other disposition of the PRODUCT, or (iv) any claim
     against ABBOTT for patent or trademark infringement in connection with
     the manufacture, use or sale of the PRODUCT.  ABBOTT shall have the
     exclusive right to control the defense of any action which is to be
     indemnified in whole by ABBOTT hereunder, including the right to
     select counsel reasonably acceptable to MEDIMMUNE to defend MEDIMMUNE,
     and to settle any claim, provided that, without the written consent of
     MEDIMMUNE (which shall not be unreasonably withheld or delayed),
     ABBOTT shall not agree to settle any claim against MEDIMMUNE.  The
     provisions of this paragraph shall survive and remain in full force
     and effect after any termination, expiration or cancellation of this
     Agreement and ABBOTT'S obligation hereunder shall apply whether or not
     such claims are rightfully brought.

3.2  A person or entity  that intends to claim indemnification under this
     Article 6 (the "Indemnitee") shall promptly notify the other PARTY
     (the "Indemnitor") of any loss, claim, damage, liability or action in
     respect of which the Indemnitee intends to claim such indemnification,
     and the Indemnitor, after it determines that indemnification is
     required of it, shall assume the defense thereof with counsel mutually
     satisfactory to the PARTIES; provided, however, that an Indemnitee
     shall have the right to retain its own counsel, with the fees and
     expenses to be paid by the Indemnitor if Indemnitor does not assume
     the defense, or if representation of such Indemnitee by the counsel
                                 (PAGE 9)
     retained by the Indemnitor would be inappropriate due to actual or
     potential differing interests between such Indemnitee and any other
     person represented by such counsel in such proceedings.  The indemnity
     agreement in this Article shall not apply to amounts paid in
     settlement of any loss, claim, damage, liability or action if such
     settlement is effected without the consent of the Indemnitor, which
     consent shall not be withheld or delayed unreasonably.  The failure to
     deliver notice to the Indemnitor within a reasonable time after the
     commencement of any such action, if prejudicial to its ability to
     defend such action, shall relieve such Indemnitor of any liability to
     the Indemnitee under this Article, but the omission so to deliver
     notice to the Indemnitor will not relieve it of any liability that it
     may have to any Indemnitee otherwise than under this Article. The
     Indemnitee under this Article, its employees and agents, shall
     cooperate fully with the Indemnitor and its legal representatives in
     the investigations of any action, claim or liability covered by this
     indemnification.  In the event that each PARTY claims indemnity from
     the other and one PARTY is finally held liable to indemnify the other,
     the Indemnitor shall additionally be liable to pay the reasonable
     legal costs and attorneys' fees incurred by the Indemnitee in
     establishing its claim for indemnity.

4.   TERM AND TERMINATION

4.1  Except if sooner terminated as provided herein, this Agreement shall
     be effective as of the date hereof and shall continue for so long as
     MEDIMMUNE or its AFFILIATE is selling PRODUCT in the TERRITORY.

4.2  Expiration or termination of this Agreement shall not relieve the
     PARTIES of any obligation accruing prior to such expiration or
     termination nor preclude either PARTY from pursuing all rights and
     remedies it may have hereunder or at law or in equity with respect to
     any breach of this Agreement nor prejudice either PARTY's right to
     obtain performance of any obligation provided for in this Agreement
     which expressly survives expiration or termination.  The provisions of
     Article 3 and Sections 4.2, 4.5, 5.7, 5.11, 5.12, and 5.15 shall
     survive the expiration or termination of this Agreement as well as any
     other provision which by its intent is meant to survive expiration or
     termination of this Agreement.

4.3  Notwithstanding any other provision of this Agreement, either PARTY
     may terminate this Agreement by notice in writing to the other upon or
     at any time after the occurrence of any of the following events:

               (i)  if the other commits a material breach of this
          Agreement  which (a) in the case of a breach capable of a remedy,
          shall not have been remedied within sixty (60) days of the
          receipt by the other of written notice identifying the breach and
          requiring its remedy and (b) continues to exist at the time of
          notice of
                                 (PAGE 10)
               termination; or

               (ii) if the other is unable to pay its debts, becomes
          bankrupt or insolvent, or enters into liquidation whether
          compulsorily or voluntarily, or compound with or convenes a
          meeting of its creditors, or has a receiver appointed over all or
          part of its assets, or takes or suffers any similar action in
          consequence of a debt, or ceases for any reason to carry on
          business.

4.4  If the THRESHOLD set forth in Section 2.4 has not been or is not going
     to be achieved in a YEAR, after the first YEAR, either PARTY shall
     have the right to terminate this Agreement by written notice to the
     other PARTY no earlier than April 1 and no later than April 30th of
     the applicable YEAR effective at the end of such YEAR, provided,
     however, that by written notice to MEDIMMUNE given within twenty (20)
     days following ABBOTT's receipt of MEDIMMUNE's termination notice,
     ABBOTT may elect to pay MEDIMMUNE (CONFIDENTIAL TREATMENT HAS BEEN
     REQUESTED) of the difference between the THRESHOLD for the applicable
     YEAR and the NET SALES of PRODUCT for the applicable YEAR, in which
     case the Agreement shall not be terminated.  Such amount shall be paid
     within (CONFIDENTIAL TREATMENT HAS BEEN REQUESTED) days after the end
     of the subject YEAR.  The provisions of this Section 4.4 shall not be
     applicable if the failure by ABBOTT to reach the THRESHOLD results
     from an inability of MEDIMMUNE to timely deliver PRODUCT.

4.5  Upon termination of this Agreement, ABBOTT shall have no further
     rights whatsoever in the PRODUCT in the TERRITORY, including but not
     limited to any rights to co-promote the PRODUCT or to the payment set
     forth hereunder.

4.6  Notwithstanding any other provision of this Agreement, MEDIMMUNE may
     suspend or terminate sale of PRODUCT if the FDA takes any action the
     result of which is to prohibit or restrict the manufacture or sale or
     introduction into interstate commerce of the PRODUCT.  Such
     termination or suspension shall not be deemed a termination of this
     Agreement.  MEDIMMUNE shall promptly notify ABBOTT of any such action
     by the FDA.

4.7  Notwithstanding any other provision of this Agreement, upon six (6)
     months prior written notice to ABBOTT, MEDIMMUNE may terminate,
     manufacture, and/or use, and/or sale of PRODUCT in the TERRITORY,
     within its sole discretion and thereby terminate this Agreement.  Such
     termination shall not be deemed a breach of this Agreement.

5.   MISCELLANEOUS

5.1  Independent Contractor.  The relationship between MEDIMMUNE and ABBOTT
     is that of independent contractors.  MEDIMMUNE and ABBOTT  are not
     joint venturers, partners, principal and agent, master and servant,

     employer or employee, and have no relationship other than as
     independent contracting parties.  MEDIMMUNE shall have no power to
     bind or obligate ABBOTT in any manner.  Likewise, ABBOTT shall have no

     responsibility for the hiring, firing, compensation or employee's
     benefits of the other PARTY'S employees.

5.2  Nonassignability. This Agreement may not be assigned or otherwise
     transferred by either PARTY without the consent of the other PARTY;
     provided, however, that either PARTY may, without such consent, assign
     this Agreement and its rights and obligations hereunder to its
     AFFILIATES or in connection with the transfer or sale of all or
     substantially all of its business to which this Agreement relates, or
     in the event of its merger or consolidation or change in control or
     similar transaction.  Any purported assignment in violation of the
     preceding sentences shall be void.  Any permitted assignee shall
     assume all obligations of its assignor under this Agreement, provided
     that such assigning party shall remain primarily liable hereunder in
     the case of an assignment to an AFFILIATE.

5.3  Modification.  This Agreement constitutes the entire agreement among
     the PARTIES with respect to the subject matter hereof and supersedes
     all prior agreements, understandings, and discussions, whether oral or
     written of the PARTIES with respect to the subject matter hereof.  Any
     modification of this Agreement shall be effective only when in writing
     and signed by the PARTIES  and specifically states that it is an
     amendment to this Agreement.

5.5  Severability.  If any provision(s) of this Agreement are or become
     invalid, are ruled illegal by any court of competent jurisdiction or
     are deemed unenforceable under then current applicable law from time
     to time in effect during the term hereof, it is the intention of the
     PARTIES that the remainder of this Agreement shall not be affected
     thereby provided that a PARTY's rights under this Agreement are not
     materially affected.  It is further the intention of the PARTIES that
     in lieu of each such provision which is invalid, illegal, or
     unenforceable, there be substituted or added as part of this Agreement
     a provision which shall be as similar as possible in economic and
     business objectives as intended by the PARTIES to such invalid,
     illegal or unenforceable provision, but shall be valid, legal and
     enforceable.  In the event a party's rights are materially affected as
     a result of a change in this Agreement under this Section, such PARTY
     may terminate this Agreement.

5.6  Public Announcements.  MEDIMMUNE and ABBOTT each agrees not to
     disclose any terms or conditions of this Agreement to any third party
     or to make any public statement about this Agreement or wherein the
     name of the other PARTY is used without the prior written consent of
     the other PARTY (which shall not be unreasonably withheld or delayed),
     except as is required by applicable law, rule or regulation; provided
     (i) that if this Agreement is required to be filed as part of any
     public document the filing PARTY shall, to the fullest extent
     permitted under such law, rule or regulation, request that
     confidential treatment be afforded to this Agreement; or (ii) that
     either PARTY may allow a third party to review this Agreement as part
     of an overall due diligence examination of such PARTY in connection
     with any potential financing, acquisition, disposition or other
     business combination; provided that such third  party is under
     obligation of confidentiality.  In the event of a disclosure permitted
                                 (PAGE 13)
     under  this Section, the disclosing PARTY shall nonetheless provide
     the non-disclosing PARTY with notice of such disclosure prior to
     disclosure, and will, to the extent reasonably possible, provide the
     non-disclosing PARTY with an opportunity to correct same.  A PARTY
     shall not be required to provide the other PARTY with a disclosure
     which has been previously provided to a PARTY.

5.7  Applicable Law.  This Agreement shall be governed by and construed in
     accordance with the laws of the State of Maryland with regard to
     choice of law principles.

5.8  Force Majeure. Neither PARTY shall be held liable or responsible to
     the other PARTY nor be deemed to have defaulted under or breached this
     Agreement for failure or delay in fulfilling or performing any term of
     this Agreement other than a payment provision when such failure or
     delay is caused by or results from causes beyond the reasonable
     control of the affected PARTY including but not limited to fire,
     floods, embargoes, war, acts of war (whether war be declared or not),
     insurrections, riots, civil commotions, strikes, lockouts or other
     labor disturbances, acts of God or acts, omissions or delays in acting
     by any governmental authority or the other PARTY.  Upon the occurrence
     of such event, the affected PARTY shall give prompt written notice of
     such event to the other PARTY.

5.9  Waiver. Any delay in enforcing a PARTY's rights under this Agreement
     or any waiver as to a particular default or other matter shall not
     constitute a waiver of a PARTY's right to the future enforcement of
     its rights under this Agreement, excepting only as to an expressed
     written and signed waiver as to a particular matter for a particular
     period of time.

5.10 Counterparts.  This Agreement may be executed in two or more
     counterparts, each of which shall be deemed an original, but all of
     which together shall constitute one and the same instrument.

5.11 Nondisclosure Obligations.

     (a)  During the term of this Agreement, it is contemplated that a
     PARTY will disclose to the other PARTY proprietary and confidential
     technology, specifications, technical information and the like which
     are owned or controlled by a PARTY ("Confidential Information").  The
     receiving PARTY agrees to retain the disclosing PARTY's Confidential
     Information in confidence and not to disclose any such Confidential
     Information to a THIRD PARTY without the prior written consent of the
     disclosing PARTY and to use the disclosing PARTY's Confidential
     Information only for the purposes of this Agreement.  The obligations
     of confidentiality will not apply to Confidential Information which:
                                 (PAGE 14)

                    (i)  was known to the receiving PARTY or generally
               known to the public prior to its disclosure hereunder;
                                     
                    (ii) subsequently becomes known to the public by some
               means other than a breach of this Agreement;

                    (iii)is subsequently disclosed to the receiving PARTY
               by a third party having a lawful right to make such
               disclosure;

                    (iv) is required by law or bona fide legal process to
               be disclosed provided that the receiving PARTY takes all
               reasonable steps to restrict and maintain confidentiality of
               such disclosure and provides reasonable prior notice to the
               disclosing PARTY; or

       customary for such a manufacturing agreement.
       In particular, the parties hereby agree that the pricing from
       THOMAE for the manufactured Product under such manufacturing
       agreement shall be in accordance with a volume discount pricing
       matrix and basic production assumptions, both set forth in APPENDIX
       11 attached hereto, which pricing matrix will establish an absolute
       initial price ceiling for Product under the manufacturing agreement
       and will provide a framework to establish Product costs for
       variable length production campaigns.

       Moreover, such manufacturing agreement shall contain a "Rolling
       Forecast Planning System for Product (Commercial Manufacture)"
       attached hereto as APPENDIX 12.

       In APPENDIX 9 MEDIMMUNE has set forth its present forecast
       estimation of its latest requirements of the Product. This forecast
       is non-binding; however, THOMAE's capacity planning for commercial
       manufacture is based on and limited by MEDIMMUNE's forecast.

              THOMAE will be informed and must agree prior to filing of any 
              THOMAE confidential Information to regulatory authorities. In 
              these case where THOMAE restricts MEDIMMUNE's ability to file

       Confidential Information and THOMAE Confidential Information shall
       not apply to any information that is:
       
       (a)    known publicly or becomes known publicly through no fault of
              the recipient;
       
       (b)    learned by the recipient from a third party entitled to
              disclose it;
       
       (c)    developed by the recipient independently of information
              obtained from the disclosing party;
       
       (d)    already known to the recipient before receipt from the
              disclosing party, as shown by its prior written records;
       
       (e)    required to be disclosed by law, regulation or the order of
              a judicial or administrative authority; or
       
       (f)    released with the prior written consent of the disclosing
              party.

11.4   Except as granted under this Agreement, no right or license, either
       express or implied, under any patent or proprietary right is
       granted hereunder by virtue of the disclosure of MEDIMMUNE
       Confidential Information or THOMAE Confidential Information.

11.5   Either party shall be entitled to injunctive relief in the event of
       a breach of this Agreement by the other party. The obligations of
       both parties under this Article 11 shall survive the expiration or
       termination of this Agreement. Both MEDIMMUNE and THOMAE shall use
       reasonable and customary precautions to safeguard MEDIMMUNE
       Confidential Information and THOMAE Confidential Information,
       including ensuring that all employees or consultants who are pro
       vided access to such information are informed of the confidential
       and proprietary nature of such information and understand that all
       such information is required to be maintained confidential.

              purposes only and except as required to meet THOMAE's obligations
              under the manufacturing agreement. THOMAE's responsibility to keep
              and store the Cell line and any other materials shall terminate 6
              six months after expiration or termination of this Agreement, and

     PRODUCT in countries of the TERRITORY as to which ABBOTT maintains
     distribution rights under this AGREEMENT ; (ii) will only sell in the

     MEDIMMUNE for approval, which approval shall not unreasonably be

     labeling and packaging unless MEDIMMUNE provides ABBOTT written
     objection thereto within twenty (20) days after receipt thereof.

2.4  ABBOTT agrees not to sell PRODUCT through subdistributors without the
     written consent of MEDIMMUNE, which consent shall not be unreasonably
     withheld.  If such consent is granted, ABBOTT shall remain fully
     liable and responsible to MEDIMMUNE for the activities of a
     subdistributor appointed by ABBOTT.
3.   PURCHASE OF PRODUCTS

3.1  (a)  Subject to Section 3.4 hereof, MEDIMMUNE shall sell and ABBOTT
     shall purchase an amount of PRODUCT equal to ABBOTT's requirements in
     the TERRITORY.  ABBOTT shall pay the price for such PRODUCT as set
     forth in Section 3.2 according to the volume purchased.

     maintain sufficient inventories of PRODUCT to enable ABBOTT to

     SALES of PRODUCT sold by ABBOTT or its AFFILIATES:

               (i)  (CONFIDENTIAL TREATMENT HAS BEEN REQUESTED)

               (ii) (CONFIDENTIAL TREATMENT HAS BEEN REQUESTED)

     (b)  (CONFIDENTIAL TREATMENT HAS BEEN REQUESTED)

3.3  (a)  MEDIMMUNE will invoice ABBOTT for PRODUCT shipped and ABBOTT
     shall pay as follows:

               (i)  (CONFIDENTIAL TREATMENT HAS BEEN REQUESTED)

                      (A)  (CONFIDENTIAL TREATMENT HAS BEEN REQUESTED)

                      (B)  (CONFIDENTIAL TREATMENT HAS BEEN REQUESTED)

                      (C)  (CONFIDENTIAL TREATMENT HAS BEEN REQUESTED)

               (ii) The price set forth in Section 3.2 shall be calculated
          and paid quarterly within forty-five (45) days following the end
          of each CALENDAR QUARTER with the amount paid under Section
          3.3(a)(i) for PRODUCT sold in a CALENDAR QUARTER (on a first in
                                 (PAGE 4)
          first out basis) being credited against the actual amount due
          under this Section 3.3 (a)(ii) for such CALENDAR QUARTER.  In the
          event that the credit exceeds the amount due for a CALENDAR
          QUARTER, then such excess amount shall be credited until
          exhausted against amounts due under this Section 3.3(a)(ii) for
          subsequent CALENDAR QUARTERS, but only if such excess results
          from payments which are made based on UNIT SALE PRICE.  If at the
          end of a CONTRACT YEAR a carry over credit exists, then MEDIMMUNE
          shall promptly pay to ABBOTT an amount equal to such carry over
          credit.  Each such quarterly payment shall be supported by the
          accounting prescribed in Section  3.3(b).   Whenever for the
          purpose of calculating payment, conversion from any foreign
          currency shall be required, such conversion shall be completed
          for each month of the CALENDAR QUARTER as follows: (CONFIDENTIAL
          TREATMENT HAS BEEN REQUESTED), using central bank fixing rates in
          countries where available and open market rates otherwise.

               (iii) (CONFIDENTIAL TREATMENT HAS BEEN REQUESTED)

               (iv) An example using the formulas set forth in this Section
          3.3(a) is attached hereto as Schedule B.

     (b)  With each quarterly payment, ABBOTT shall deliver to MEDIMMUNE a
     full and accurate accounting to include at least the following
     information:

               (i)  Quantity of each PRODUCT sold and/or withdrawn by
          transaction type (by country) by ABBOTT, and its AFFILIATES and
          if applicable, it's subdistributors.

               (ii) Total amount invoiced for each PRODUCT (by country) in
          local currency.

          currency.

               (iv) Exchange rates for converting each local currency into
          U.S. Dollars for each month of the CALENDAR QUARTER.

               (v)  NET SALES in U.S. dollars in each country.

               (vi) Total compensation payable to MEDIMMUNE.

               (vii)Credits taken by ABBOTT pursuant to Section 3.3(a)(ii).

     (c)  Within forty five (45) days following each CONTRACT YEAR, ABBOTT
     shall provide MEDIMMUNE an inventory reconciliation for such CONTRACT
                                 (PAGE 5)
     YEAR.

     (d)  ABBOTT shall keep, and shall cause each of its AFFILIATES to
     keep, and if applicable, its subdistributors, full and accurate books
     of account containing all particulars that may be necessary for the
     purpose of calculating all payments payable to MEDIMMUNE.  Such books
     of account shall be kept at their principal place of business and,
     with all necessary supporting data shall, for the two (2) years next
     following the end of the calendar year to which each shall pertain be
     open for inspection by an independent certified accountant selected by
     MEDIMMUNE and reasonably acceptable to ABBOTT upon reasonable notice
     during normal business hours at MEDIMMUNE's expense for the sole
     purpose of verifying payments or compliance with this AGREEMENT, but
     in no event more than once in each calendar year.  All information and
     data offered shall be used only for the purpose of verifying payments.
     In the event that such inspection shall indicate that in any calendar
     year that the payments which should have been paid by ABBOTT are at
     least five percent (5%) greater than those which were actually paid by
     ABBOTT, then ABBOTT shall pay the cost of such inspection.  All
     underpayments are immediately due and payable.

     (e)  MEDIMMUNE shall forward all invoices for PRODUCT ordered
     hereunder to a U.S. location as designated by ABBOTT.

3.4  MEDIMMUNE shall use commercially reasonable efforts to satisfy
     ABBOTT's requirements for PRODUCT.  All PRODUCT shipped to ABBOTT
     shall be manufactured in accordance with the SPECIFICATIONS.
     MEDIMMUNE shall promptly advise ABBOTT of any proposed or required
     changes to the SPECIFICATIONS.  To the extent such changes require a
     new or amended Product Registration, as defined herein, MEDIMMUNE and
     ABBOTT shall cooperate and coordinate the adoption of such changes to
     the SPECIFICATIONS so as to minimize any disruption of the marketing,
     promotion and sale of PRODUCT in any country within the TERRITORY.
     However, MEDIMMUNE's obligation to supply PRODUCT under Section 3.1
     hereof shall at all times be subject to the condition that MEDIMMUNE
     is able to obtain or make a sufficient supply of such PRODUCT for sale
     both inside and outside of the TERRITORY.  In the event that PRODUCT
     available to MEDIMMUNE is in short supply, MEDIMMUNE shall notify
     ABBOTT of such shortage as soon as possible.  In the event there is a
     short supply of PRODUCT and MEDIMMUNE cannot supply PRODUCT to ABBOTT
     in an amount equal to ABBOTT's FIRM ORDER, then MEDIMMUNE shall
     allocate available PRODUCT to ABBOTT in each month that such a
     shortfall exists (and in each month thereafter until the shortfall to
     ABBOTT is remedied) in an amount equal to the product of (i) the
     amount of available PRODUCT for that month and (ii) a fraction the
     numerator of which is the aggregate quantity of FIRM ORDERS made by
     ABBOTT over the subsequent twelve (12) month period including the
                                 (PAGE 6)
     shortfall month and the denominator of which is the sum of (x) the
     aggregate quantity of FIRM ORDERS made by ABBOTT over the subsequent
     twelve (12) month period including the shortfall months and (y) the
     aggregate quantity of PRODUCT over the same twelve (12) month period
     required by MEDIMMUNE outside the TERRITORY by reference to FIRM
     ORDERS placed with THIRD PARTY manufacturers for MEDIMMUNE's
     requirements and the amount to be produced at a MEDIMMUNE facility for
     MEDIMMUNE's requirements, in each case outside the TERRITORY.

3.5  ABBOTT agrees to use and distribute the PRODUCT only in accordance
     with the terms, conditions and purposes of this AGREEMENT.

4.   DELIVERY, PAYMENT AND RISK OF LOSS

4.1  (a)  All payments under this AGREEMENT shall be remitted in
     immediately available funds.  Unless otherwise agreed between the
     parties all payments shall be in U.S. Dollars.

     (b)  In the event that any payment due hereunder is not made when due,
     the payment shall accrue interest beginning on the first day of the
     month following the date when such payment was due, calculated at the
     annual rate of the sum of (i) two percent (2%) plus (ii) the prime
     interest rate quoted by Citibank, N.A., New York, New York, on the
     date such payment is due, or on the date payment is made, whichever is
     higher, the interest being compounded on the last day of each calendar
     month; provided that in no event shall said annual rate exceed the
     maximum legal interest rate for corporations.  Such payment when made
     shall be accompanied by all interest accrued.  Said interest and the
     payment and acceptance thereof shall not negate or waive the right of
     MEDIMMUNE to any other remedy, legal or equitable, to which MEDIMMUNE
     may be entitled because of the delinquency of the payment.

4.2  Title to PRODUCT sold hereunder, and risk of loss with respect to such
     PRODUCT, shall pass to ABBOTT upon delivery of the PRODUCT to a
     carrier designated by ABBOTT at the place at which PRODUCT is
     manufactured.  ABBOTT shall be responsible for the cost of freight and
     insurance.  Upon the passage of title, MEDIMMUNE's liability with
     respect to risk of loss shall cease, and ABBOTT shall be the owner of
     such PRODUCT for all purposes, including, without limitation, the
     marketing, sale and setting of prices for the PRODUCT sold by ABBOTT
     to its customers.

4.3  No provision on ABBOTT's purchase order forms which may purport to
     impose different conditions upon the parties hereto shall modify the
     terms of this AGREEMENT.

                                 (PAGE 7)
4.4  After the sale of PRODUCT to ABBOTT, ABBOTT shall ship such PRODUCT
     outside the country in which ABBOTT takes title.

5.   FORECASTS AND ORDERS

5.1  (a)  ABBOTT shall provide MEDIMMUNE on the tenth of the last month of
     each quarter with a three-year product forecast planning horizon.  The
     rolling forecasts are to be broken down to single months.  The
     forecasts within the first year (month 1 through 12) are firm orders
     and cannot be changed.   The forecast for the second year (month 13
     through 24) is a partly binding forecast which means that the forecast
     can be changed within this period.  The forecast can be increased, but
     is limited to the following restrictions when decreased.

          Month 13 - 15 -- the forecast can be reduced by
          (CONFIDENTIAL TREATMENT HAS BEEN REQUESTED)
          Month 16 - 18 -- the forecast can be reduced by
          (CONFIDENTIAL TREATMENT HAS BEEN REQUESTED)
          Month 19 - 21 -- the forecast can be reduced by
          (CONFIDENTIAL TREATMENT HAS BEEN REQUESTED)
          Month 21 - 24 -- the forecast can be reduced by
          (CONFIDENTIAL TREATMENT HAS BEEN REQUESTED)
          The forecast for the third year (month 25 - 36) is
          a non-binding forecast.

     Notwithstanding the foregoing, MEDIMMUNE shall make every reasonable
     effort to comply with unplanned changes in FIRM ORDERS, but shall not
     be held liable for its inability to do so.  In each FIRM ORDER for any
     month, ABBOTT shall state, after consultation with MEDIMMUNE, a
     reasonable delivery schedule for PRODUCTS to be delivered in that
     month.  With respect to calendar year 1998, the parties shall agree on
     or before February 15, 1998, upon a FIRM ORDER for that calendar year
     and the partly binding and non-binding estimates for the following
     twenty four (24) months.

     (b)  Notwithstanding the foregoing, MEDIMMUNE reserves the right to
     spread the supply of PRODUCT throughout a CONTRACT YEAR
     
     (c)  PRODUCT shall be provided to ABBOTT by MEDIMMUNE and shall be
     ordered by ABBOTT in 50 mg or 100 mg vials; without labeling or
     packaging.  ABBOTT shall be responsible for the labeling and packaging
     of PRODUCT, at ABBOTT's sole cost and expense.

     (d)  In any month for which ABBOTT places an order, the order shall be
     no less than 1000 vials of PRODUCT, and MEDIMMUNE shall only be
     required to deliver PRODUCT to ABBOTT once in each month.
                                 (PAGE 8)
5.2  ABBOTT shall have sixty (60) days from receipt of any delivery of
     PRODUCT to examine such PRODUCT.  ABBOTT shall promptly notify
     MEDIMMUNE of any defective PRODUCT and shall return to or otherwise
     dispose of any defective shipments in accordance with MEDIMMUNE'S
     instructions at MEDIMMUNE'S cost and expense.  Subject to Section 3.4
     MEDIMMUNE shall provide for replacement delivery within one (1) month
     from existing production stock of the THIRD PARTY manufacturer, if
     available, and if not available, within twelve (12) months therefrom.
     Such replacement shall be ABBOTT's sole and exclusive remedy with
     respect to defective PRODUCT delivered by MEDIMMUNE hereunder.

6.   DILIGENCE

6.1  MEDIMMUNE shall, as soon as practical after execution of this
     AGREEMENT provide ABBOTT with all data and information which MEDIMMUNE
     has in its possession with respect to PRODUCT which is necessary for
     ABBOTT to obtain appropriate PRODUCT approvals in the TERRITORY, which
     data and information includes, but is not limited to, the PRODUCT BLA
     filing with the United States Food and Drug Administration.  MEDIMMUNE
     shall provide ABBOTT reasonable technical assistance and cooperation
     in connection with ABBOTT's efforts in obtaining regulatory approval
     of PRODUCT in each MAJOR MARKET.

6.2  At its sole cost and expense, ABBOTT shall exert best efforts to
     obtain in each MAJOR MARKET all approvals which are required to enable
     ABBOTT to sell and distribute PRODUCT in each MAJOR MARKET including
     but not limited to regulatory and pricing approvals.  In the event
     that clinical trial(s) is required to obtain or maintain such
     approvals in a country(ies) of the TERRITORY, then ABBOTT shall have
     the right to terminate this AGREEMENT in such country(ies) by written
     notice to MEDIMMUNE within the following time periods after ABBOTT is
     notified that clinical trial(s) for PRODUCT is required in such
     country:

               (i)  within thirty (30 ) days if ABBOTT's good faith
          estimate of the cost to complete such clinical trial is less than
          (CONFIDENTIAL TREATMENT HAS BEEN REQUESTED);

               (ii) within sixty (60 ) days if ABBOTT's good faith estimate
          of the cost to complete such clinical trial is greater than
          (CONFIDENTIAL TREATMENT HAS BEEN REQUESTED);

               (iii)within ninety (90 ) days if ABBOTT's good faith
          estimate of the cost to complete such clinical trial is greater
          than (CONFIDENTIAL TREATMENT HAS BEEN REQUESTED);
                                 (PAGE 9)
               (iv) within one hundred twenty (120 ) days if ABBOTT's good
          faith estimate of the cost to complete such clinical trial is
          greater than (CONFIDENTIAL TREATMENT HAS BEEN REQUESTED);

          With respect to a country(ies) in the TERRITORY in which this
          AGREEMENT is terminated pursuant to this Section 6.2, ABBOTT
          hereby grants to MEDIMMUNE a royalty free license to use any and
          all technical, clinical and regulatory information, filings and
          licenses of ABBOTT with respect to such PRODUCT in such
          country(ies) and ABBOTT shall effect prompt transfer thereof to
          MEDIMMUNE.

6.3  ABBOTT shall take any and all necessary steps to maintain regulatory
     and pricing approval for PRODUCT in each country of the TERRITORY in
     which it is obtained.

6.4  Prior to initiating a clinical trial with respect to PRODUCT, the
     PARTY who is to conduct such clinical trial shall provide the other
     PARTY with an opportunity to review the clinical trial proposal and
     such PARTY shall consider any advice and suggestions of the other
     PARTY with respect to such clinical trial.  In the case of a clinical
     trial to be conducted by or on behalf of ABBOTT with respect to
     PRODUCT, such clinical trial shall not be initiated without the
     written consent of MEDIMMUNE, which consent shall not be unreasonably
     withheld.

6.5  In the event that, notwithstanding ABBOTT's best efforts, ABBOTT does
     not achieve the following milestones in the TERRITORY, MEDIMMUNE may,
     in its sole discretion, convert the exclusive rights granted herein to
     non-exclusive rights:

               (i)  (CONFIDENTIAL TREATMENT HAS BEEN REQUESTED)

6.6  In the event that ABBOTT does not have a significant interest in
     obtaining regulatory approval of and marketing PRODUCT in any country
     of the TERRITORY, ABBOTT shall notify MEDIMMUNE.  If MEDIMMUNE
     requests in writing that ABBOTT indicate whether or not ABBOTT has an
     interest in marketing PRODUCT in a country(ies) of the TERRITORY,
     within thirty (30) days thereafter ABBOTT shall notify MEDIMMUNE as to
     whether or not ABBOTT has such an interest.  In the event that ABBOTT
     notifies MEDIMMUNE that it does not have a significant interest in
     marketing PRODUCT in any country(ies) of the TERRITORY, MEDIMMUNE may
     terminate ABBOTT's rights in such country(ies) of the TERRITORY,
     provided that the marketing in such country(ies) does not adversely
     affect marketing of PRODUCT in a country in which ABBOTT is seeking or
     has obtained regulatory approval.

                                 (PAGE 10)

               (i)  (CONFIDENTIAL TREATMENT HAS BEEN REQUESTED).

               (ii) (CONFIDENTIAL TREATMENT HAS BEEN REQUESTED).

               (iii)(CONFIDENTIAL TREATMENT HAS BEEN REQUESTED).

               (z)  (CONFIDENTIAL TREATMENT HAS BEEN REQUESTED).

     (b)  (CONFIDENTIAL TREATMENT HAS BEEN REQUESTED).

6.8  During the term of this AGREEMENT, ABBOTT shall exercise its best
     efforts to promote the use and sale of PRODUCT in the MAJOR MARKETS of
     the TERRITORY and in each country of the TERRITORY in which PRODUCT is
     approved for sale and shall maintain, at its own cost and expense, an
     adequate sales organization for this purpose.  ABBOTT shall keep
     MEDIMMUNE advised of general market, economic and regulatory
     developments that may affect the sale of PRODUCT.

7.   PAYMENTS

     In consideration for the clinical and other data provided by MEDIMMUNE
     in support of regulatory approvals in the TERRITORY, ABBOTT will make
     the following payments to MEDIMMUNE:

               (i)  (CONFIDENTIAL TREATMENT HAS BEEN REQUESTED);
               (ii) (CONFIDENTIAL TREATMENT HAS BEEN REQUESTED);
               (iii)(CONFIDENTIAL TREATMENT HAS BEEN REQUESTED);
               (iv) (CONFIDENTIAL TREATMENT HAS BEEN REQUESTED); and
               (v)  (CONFIDENTIAL TREATMENT HAS BEEN REQUESTED).

8.   OTHER RESPONSIBILITIES OF ABBOTT

8.1  In distributing the PRODUCT in the TERRITORY, ABBOTT will comply with
     all provisions of the laws, rules and regulations applicable in the
     TERRITORY.   ABBOTT shall promptly notify MEDIMMUNE of any changes in
     such provisions.
                                 (PAGE 11)
8.2  ABBOTT agrees not to export PRODUCT outside the TERRITORY without the
     express permission of MEDIMMUNE.

     CALENDAR QUARTER indicating the quantities of the PRODUCT in inventory
     and sales of the PRODUCT in each country of the TERRITORY.

8.4  The appointment of ABBOTT hereunder shall not create a joint venture,
     or any employer-employee relationship or principal-agency
     relationship, and nothing under this AGREEMENT shall be deemed to
     authorize ABBOTT to act for, represent, or bind MEDIMMUNE or any of
     its AFFILIATES.

8.5  (a)  During the term of this AGREEMENT, it is contemplated that a
     PARTY will disclose to the other PARTY proprietary and confidential
     technology, specifications, technical information and the like which
     are owned or controlled by a PARTY ("Confidential Information").  The
     receiving PARTY agrees to retain the disclosing PARTY's Confidential
     Information in confidence and not to disclose any such Confidential
     Information to a THIRD PARTY without the prior written consent of the
     disclosing PARTY and to use the disclosing PARTY's Confidential
     Information only for the purposes of this AGREEMENT.  The obligations
     of confidentiality will not apply to Confidential Information which:

               (i)  was known to the receiving PARTY or generally known to
          the public prior to its disclosure hereunder;

               (ii) subsequently becomes known to the public by some means
          other than a breach of this AGREEMENT;

               (iii)is subsequently disclosed to the receiving PARTY by a
          third party having a lawful right to make such disclosure;

               (iv) is required by law or bona fide legal process to be
          disclosed provided that the receiving PARTY takes all reasonable
          steps to restrict and maintain confidentiality of such disclosure
          and provides reasonable prior notice to the disclosing PARTY; or

               (v)  is approved for release by the PARTIES.

     (b)  Upon termination or expiration of this AGREEMENT, each PARTY
     shall return to the other PARTY all tangible forms of confidential
     information furnished by the other PARTY, including all copies thereof
     and all memoranda of oral disclosure, except that each PARTY may
     retain one copy in its files to ensure compliance with any legal
     obligations.
                                 (PAGE 12)
     (c)  This Section shall survive until the tenth anniversary of the
     termination or expiration of this AGREEMENT.

8.6  During the term of this AGREEMENT and for one year thereafter, ABBOTT
     agrees that neither ABBOTT nor an AFFILIATE of ABBOTT shall research,
     clinically develop, promote, market or sell directly or indirectly or
     assist another party in marketing or selling in the TERRITORY any
     immunoglobulin or antibody product (or antibody derivative) for
     prevention and/or treatment of respiratory syncytial virus disease.

8.7  ABBOTT agrees to provide MEDIMMUNE with ABBOTT's annual U.S. Dollar
     sales forecast for PRODUCT to be sold in the TERRITORY for the sole
     purpose of assisting MEDIMMUNE in its financial planning.

9.   TRADEMARKS, LOGOS AND PATENTS

9.1  ABBOTT shall propose to MEDIMMUNE trademarks for use with the PRODUCT
     in the TERRITORY, and with the written consent of MEDIMMUNE a proposed
     trademark(s) shall become the TRADEMARK for the PRODUCT in the
     TERRITORY.

9.2  The TRADEMARK shall be owned by ABBOTT.

9.3  In the event that ABBOTT's rights to PRODUCT under this AGREEMENT are
     terminated in any country(ies) of the TERRITORY or this AGREEMENT is
     terminated for reasons other than MEDIMMUNE's breach of the terms of
     this AGREEMENT, ABBOTT shall grant to MEDIMMUNE a non-cancellable
     royalty free exclusive license to use the     TRADEMARK with respect
     to PRODUCT in such country(ies) or to all countries of the TERRITORY,
     respectively, and shall perform all acts and sign and execute any and
     all papers required to effect such licensing all at no cost or expense
     to MEDIMMUNE.

9.4  ABBOTT agrees to use the TRADEMARK only with respect to PRODUCT
     purchased from MEDIMMUNE and only in those countries of the TERRITORY
     in which ABBOTT retains the right to distribute PRODUCT.

9.5  At its cost and expense, ABBOTT undertakes to comply with all legal
     requirements pertaining to the TRADEMARK to maintain the TRADEMARK in
     force at all times, in the TERRITORY in which ABBOTT retains the right
     to distribute PRODUCT.

9.6  If ABBOTT becomes aware of any infringement of the TRADEMARK within
     the TERRITORY, ABBOTT shall, at its expense, take such steps as ABBOTT
     may reasonably determine for the protection of its rights in the
     TRADEMARK.  The commencement, strategies, termination and settlement
     of any action relating to the validity and/or infringement of such
                                 (PAGE 13)
     TRADEMARK shall be finally decided by ABBOTT.

9.7  (a)  The patents in the TERRITORY relating to PRODUCT owned by or
     licensed to MEDIMMUNE are set forth in attached Schedule C.

     (b)  In the event that ABBOTT notifies MEDIMMUNE that ABBOTT believes
     that a THIRD PARTY is selling a monoclonal antibody against RSV in the
     TERRITORY which infringes a patent owned by or licensed to MEDIMMUNE
     and MEDIMMUNE has the right to bring suit under such patent then:

               (i)  MEDIMMUNE shall have the first right to bring an
          infringement action against such THIRD PARTY at its cost and
          expense and MEDIMMUNE shall retain all amounts recovered in such
          action; or

               (ii) if MEDIMMUNE does not initiate such action within
          thirty (30) days of written notice of such infringement from
          ABBOTT, at the request of ABBOTT, to the extent that MEDIMMUNE
          has the right to do so, MEDIMMUNE shall initiate an infringement
          action against such THIRD PARTY at the cost and expense of ABBOTT
          and ABBOTT shall retain all amounts recovered in such action.

     (c)  In any infringement suit instituted by MEDIMMUNE to enforce the
     patent rights pursuant to this AGREEMENT, ABBOTT shall cooperate fully
     with MEDIMMUNE.

10.  INDEMNITY

10.1 ABBOTT shall defend, indemnify and hold harmless MEDIMMUNE and its
     AFFILIATES and their licensors related to the PRODUCT and their
     respective employees, agents, officers, shareholders and directors and
     each of them (a "MEDIMMUNE Indemnified Party") from and against any
     and all THIRD PARTY claims, causes of action, losses, damages and
     costs (including reasonable attorney's fees) of any nature made or
     asserted against a MEDIMMUNE Indemnified Party or lawsuits or other
     proceedings filed or otherwise instituted against a MEDIMMUNE
     Indemnified Party, in each case by a THIRD PARTY (hereinafter
     individually and collectively a "Loss(es)") to the extent that such
     Loss results or arises from clinical trials, testing, sale or use of
     any PRODUCT which is used or sold by or on behalf of ABBOTT, provided,
     however, that the foregoing indemnification shall not be applicable to
     any Loss to a MEDIMMUNE Indemnified Party to the extent that such Loss
     arises or results from the negligence or willful misconduct of such
     MEDIMMUNE Indemnified Party or infringement of a patent of a THIRD
     PARTY as a result of manufacture, use or sale of PRODUCT in the
     TERRITORY.
                                 (PAGE 14)

10.2 Indemnification by MEDIMMUNE.

     MEDIMMUNE shall defend, indemnify and hold harmless ABBOTT and its
     AFFILIATES and their respective employees, agents, officers,
     shareholders and directors and each of them (a "ABBOTT Indemnified
     Party(ies)") from and against any and all THIRD PARTY claims, causes
     of action, losses, damages and costs (including reasonable attorney's
     fees) of any nature made or asserted against a ABBOTT Indemnified
     Party or lawsuits or other proceedings filed or otherwise instituted
     against a ABBOTT Indemnified Party, in each case by a THIRD PARTY
     (hereinafter individually or collectively a "Loss(es)") to the extent
     that such Loss results or arises from the negligence or willful
     misconduct of MEDIMMUNE or the infringement of a patent of a THIRD
     PARTY as a result of ABBOTT's use or sale of PRODUCT in the TERRITORY,
     except to the extent that such Loss arises from the negligence or
     willful misconduct of such ABBOTT Indemnified Party.

10.3 Conditions to Indemnification.

     A person or entity that intends to claim indemnification under this
     Section 10 (the "Indemnitee") shall promptly notify the other party
     (the "Indemnitor") of any loss, claim, damage, liability or action in
     respect of which the Indemnitee intends to claim such indemnification,
     and the Indemnitor shall assume the defense thereof with counsel
     mutually satisfactory to the Indemnitee whether or not such claim is
     rightfully brought; provided, however, that an Indemnitee shall have
     the right to retain its own counsel, with the fees and expenses to be
     paid by the Indemnitor if Indemnitor does not assume the defense, or
     if representation of such Indemnitee by the counsel retained by the
     Indemnitor would be inappropriate due to actual or potential differing
     interests between such Indemnitee and any other person represented by
     such counsel in such proceedings.  The indemnity agreement in this
     Section 10 shall not apply to amounts paid in settlement of any loss,
     claim, damage, liability or action if such settlement is effected
     without the consent of the Indemnitor, which consent shall not be
     withheld or delayed unreasonably.  The failure to deliver notice to
     the Indemnitor within a reasonable time after the commencement of any
     such action, only if prejudicial to its ability to defend such action,
     shall relieve such Indemnitor of any liability to the Indemnitee under
     this Section 10, but the omission so to deliver notice to the
     Indemnitor will not relieve it of any liability that it may have to
     any Indemnitee otherwise than under this Section 10.  The Indemnitee
     under this Section 10, its employees and agents, shall cooperate fully
     with the Indemnitor and its legal representatives in the
     investigations of any action, claim or liability covered by this
     indemnification.
                                 (PAGE 15)

11.  CLINICAL TRIALS AND ADVERSE REACTION REPORTING

11.1 Each party hereto shall be responsible for the conduct of clinical
     trials, including drug monitoring with PRODUCT in its territory and
     the parties will keep each other informed and share data resulting
     from such clinical trials.

11.2 In order to guarantee that all applicable regulatory requirements as
     well as the PARTIES' interests regarding pharmacovigilance of the
     medicinal products concerned can be met, the PARTIES shall exchange
     appropriate information.  The PARTIES shall make sufficient efforts to
     promptly establish and adopt sufficient procedures concerning this
     exchange.  These procedures shall be documented in writing as Schedule
     D to this AGREEMENT.

11.3 Each PARTY agrees to notify the other PARTY as soon as possible of any
     information it may receive regarding any threatened or pending action
     by an AGENCY which may affect the safety or efficacy claims of PRODUCT
     or the continued marketing of such PRODUCT.

11.4 Each PARTY shall promptly notify the other PARTY in writing of any
     facts relating to the advisability of the recall, destruction or
     withholding from the market of the PRODUCT anywhere in the world
     (collectively, "Recall").  If at any time (a) any governmental or
     regulatory authority in the TERRITORY issues a request, directive or
     order for a Recall; (b) a court of competent jurisdiction orders a
     Recall in the TERRITORY; or (c) ABBOTT determines, following
     consultation with MEDIMMUNE (except in emergency situations in which
     there is insufficient time for such consultation), that a Recall in
     the TERRITORY is necessary or advisable, ABBOTT shall take all
     appropriate corrective actions, at ABBOTT's expense, to effect the
     Recall and MEDIMMUNE shall provide ABBOTT with such cooperation in
     connection with the Recall as ABBOTT may reasonably request.

12.  WARRANTIES

12.1 Each party warrants and represents that it has the full right and
     authority to enter into this AGREEMENT and that it is not aware of any
     impediment which would inhibit its ability to perform the terms and
     conditions imposed on it.

12.2 EXCEPT AS OTHERWISE EXPRESSLY SET FORTH IN THIS SECTION 12, NEITHER
     PARTY MAKES ANY REPRESENTATION OR EXTENDS ANY WARRANTIES OF ANY KIND
     EITHER EXPRESS OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, WARRANTIES
     OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, OR VALIDITY OF
     ANY PATENTS ISSUED OR PENDING.
                                 (PAGE 16)
13.  TERM AND TERMINATION

13.1 This AGREEMENT is effective as of the date first above written and,
     unless sooner terminated as provided herein, shall continue for as
     long as ABBOTT is distributing the PRODUCT in the TERRITORY.

13.2 This AGREEMENT may be terminated by either party if:

     (a)  (i) the other party fails to observe, perform or otherwise
     breaches any of its material covenants, agreements or obligations
     under this AGREEMENT in any material respect and (ii) such failure
     continues for a period of thirty (30) days after receipt by the other
     party of notice thereof from the electing party specifying such
     failure.  Following such period, the electing party has ninety (90)
     days to give notice to the other party of its election to terminate
     this AGREEMENT; or

     (b)  (i) the other party files or institutes bankruptcy,
     reorganization, liquidation, receivership or similar proceedings under
     any debt relief laws or fails for more than sixty (60) days to take
     steps to oppose the initiation of such actions against it.

13.3 Upon the termination of this AGREEMENT for any reason other than for
     breach of this AGREEMENT by ABBOTT, ABBOTT shall have the right to
     sell all PRODUCT in inventory at the time of termination.  All such
     sales of PRODUCT shall be subject to the terms of this AGREEMENT, as
     in effect immediately prior to termination.  If this AGREEMENT
     terminates for any breach by ABBOTT, then MEDIMMUNE may at its
     discretion buy back all or part of the PRODUCT that remain in the
     possession of ABBOTT and are in good condition with a reasonable
     remaining shelf life.  All PRODUCT which is not repurchased by
     MEDIMMUNE within four (4) weeks after termination shall be immediately
     destroyed by ABBOTT at ABBOTT's expense.  Upon termination, ABBOTT
     shall discontinue use of the TRADEMARK, except in connection with any
     sale of inventory as provided in this Section.

13.4 The termination of this AGREEMENT shall not affect any outstanding
     obligations of ABBOTT or MEDIMMUNE hereunder, including but not
     limited to any payments owed under the provisions of this AGREEMENT
     while it was in effect and payment for binding and partially binding
     orders under Section 5.1(a).  Any such amount owed to a party shall be
     paid within thirty (30) days of the termination of this AGREEMENT.
     The provisions of Sections 3.3, 4.1, 5.1(a), 8.5, 8.6, 9.2, 9.3, 9.4,
     Section 10, 13.3, 13.4 and 14.1 shall survive the termination of this
     AGREEMENT for the longest period permitted by applicable law.

                                 (PAGE 17)
13.5 ABBOTT may obtain PRODUCT registrations, licenses, permits, consents
     and other approvals required from time to time to distribute and sell
     the PRODUCTS in a country within the TERRITORY (the "Product
     Registrations").  Upon termination of this AGREEMENT and at the
     request of MEDIMMUNE, ABBOTT shall take all necessary or appropriate
     actions to transfer to MEDIMMUNE or its designee the Product
     Registrations which ABBOTT obtained in order to import, distribute or
     sell PRODUCT in a country(ies) within the TERRITORY, to the extent
     permitted by applicable law and regulation.

14.  MISCELLANEOUS PROVISIONS

14.1 This AGREEMENT shall be governed by and construed in accordance with
     the laws of State of Maryland without giving effect to its conflict of
     law rules and regulations.

14.2 The United Nations Convention on the International Sale of Goods shall
     not apply to this AGREEMENT, nor to any sale of PRODUCT made pursuant
     to this AGREEMENT.

14.3 This AGREEMENT sets forth the entire agreement and understanding
     between the parties as to the subject matter thereof and supersedes
     all prior agreements in this respect.  There shall be no amendments or
     modifications to this AGREEMENT, except by a written document which is
     signed by both parties.

14.4 The headings in this AGREEMENT have been inserted for the convenience
     of reference only and are not intended to limit or expand on the
     meaning of the language contained in the particular article or
     section.

14.5 Any delay in enforcing a party's rights under this AGREEMENT or any
     waiver as to a particular default or other matter shall not constitute
     a waiver of a party's right to the future enforcement of its rights
     under this AGREEMENT, excepting only as to an expressed written and
     signed waiver as to a particular matter for a particular period of
     time.

14.6 In the event any provision of this AGREEMENT should be held invalid,
     illegal or unenforceable, the remaining provisions shall not be
     affected or impaired and the parties will use all reasonable efforts
     to replace the applicable provision within a valid, legal and
     enforceable provision which insofar as practical implements the
     purposes hereof.

14.7 Unless agreed upon in writing in advance by the PARTIES, the PARTIES
     shall not discuss with THIRD PARTIES or originate any publicity, news
                                 (PAGE 18)
     release or other public announcement, written or oral, whether to the
     public press, stockholders or otherwise, any matters relating to the
     terms of this AGREEMENT without the prior written consent of the other
     PARTY except as may be required to obtain the Product Registrations.
     However, the PARTIES acknowledge and agree that MEDIMMUNE and ABBOTT
     shall be entitled to comply with the information obligations to the
     public as set out in the company laws or security laws of the U.S.

14.8 If a dispute or claim arising out of or in connection with this
     AGREEMENT develops between the PARTIES, the respective appropriate
     officers of the PARTIES shall negotiate in good faith in an effort to
     resolve the dispute for a period of thirty (30) days; provided,
     however, nothing in this Section 14.8 shall prevent either PARTY from
     seeking equitable relief.  The PARTIES may, but are not obligated to,
     agree to use the alternate dispute resolution procedure set forth in
     Schedule D.

15.  FORCE MAJEURE

     Neither party shall be liable to the other for any default hereunder,
     which is not a payment default, which is due to cause beyond the
     control of the party in default, including but not limited to the
     actions or inactions of any government agency or instrumentality;
     breakdown of plant or machinery or shortages of labor, fuel,
     transportation of materials, fires, floods, earthquakes, war, riots or
     insurrections.  If either party shall seek to rely on Force Majeure it
     shall give written notice to the other indicating the details of the
     act which it claims has put due performance of its obligations beyond
     its control.  In addition, the affected party shall exert all
     reasonable efforts to eliminate or cure any Force Majeure event and to
     resume performance with all possible speed.  In the event this cannot
     be done within six (6) months, the parties shall either resolve the
     matter by mutual agreement or terminate this AGREEMENT.

     successors and assigns.

     substantially all of its business or assets relating to this
     AGREEMENT.

EXHIBIT E
ALTRNATIVE DISPUTE RESOLUTION
                                                                           
     The parties recognize that a bona fide dispute as to certain matters
may arise from time to time during the term of this AGREEMENT which relates
to either party's rights and/or obligations.  To have such a dispute
resolved by this Alternative Dispute Resolution ("ADR") provision, a party
first must send written notice of the dispute to the other party for
attempted resolution by good faith negotiations between their respective
presidents (or their equivalents) of the affected subsidiaries, divisions,
or business units within twenty-eight (28) days after such notice is
received (all references to "days" in this ADR provision are to calendar
days).

     If the matter has not been resolved within twenty-eight (28) days of
the notice of dispute, or if the parties fail to meet within such
twenty-eight (28) days, either party may initiate an ADR proceeding as
provided herein.  The parties shall have the right to be represented by
                                 (PAGE 23)
counsel in such a proceeding.

1.  To begin an ADR proceeding, a party shall provide written notice to
    the other party of the issues to be resolved by ADR.  Within fourteen
    (14) days after its receipt of such notice, the other party may, by
    written notice to the party initiating the ADR, add additional issues
    to be resolved within the same ADR.

2.  Within twenty-one (21) days following receipt of the original ADR
    notice, the parties shall select a mutually acceptable neutral to
    preside in the resolution of any disputes in this ADR proceeding.  If
    the parties are unable to agree on a mutually acceptable neutral
    within such period, either party may request the President of the CPR
    Institute for Dispute Resolution ("CPR"), 366 Madison Avenue, 14th
    Floor, New York, New York  10017, to select a neutral pursuant to the
    following procedures:

        (a)    The CPR shall submit to the parties a list of not less than
        five (5) candidates within fourteen (14) days after receipt of the
        request, along with a Curriculum Vitae for each candidate.  No
        candidate shall be an employee, director, or shareholder of either
        party or any of their subsidiaries or affiliates.

        (b)    Such list shall include a statement of disclosure by each
        candidate of any circumstances likely to affect his or her
        impartiality.

        (c)    Each party shall number the candidates in order of
        preference (with the number one (1) signifying the greatest
        preference) and shall deliver the list to the CPR within seven (7)
        days following receipt of the list of candidates.  If a party
        believes a conflict of interest exists regarding any of the
        candidates, that party shall provide a written explanation of the
        conflict to the CPR along with its list showing its order of
        preference for the candidates.  Any party failing to return a list
        of preferences on time shall be deemed to have no order of
        preference.

        (d)    If the parties collectively have identified fewer than
        three (3) candidates deemed to have conflicts, the CPR immediately
        shall designate as the neutral the candidate for whom the parties
        collectively have indicated the greatest preference.  If a tie
        should result between two candidates, the CPR may designate either
        candidate.  If the parties collectively have identified three (3)
        or more candidates deemed to have conflicts, the CPR shall review
        the explanations regarding conflicts and, in its sole discretion,
        may either (i) immediately designate as the neutral the candidate
        for whom the parties collectively have indicated the greatest
                                 (PAGE 24)
               preference, or (ii) issue a new list of not less than five
        (5) candidates, in which case the procedures set forth in
        subparagraphs 2(a) - 2(d) shall be repeated.

3.  No earlier than twenty-eight (28) days or later than fifty-six (56)
    days after selection, the neutral shall hold a hearing to resolve each
    of the issues identified by the parties.  The ADR proceeding shall
    take place at a location agreed upon by the parties.  If the parties
    cannot agree, the neutral shall designate a location other than the
    principal place of business of either party or any of their
    subsidiaries or affiliates.

4.  At least seven (7) days prior to the hearing, each party shall submit
    the following to the other party and the neutral:

        (a)    a copy of all exhibits on which such party intends to rely
        in any oral or written presentation to the neutral;

        (b)    a list of any witnesses such party intends to call at the
        hearing, and a short summary of the anticipated testimony of each
        witness;

        (c)    a proposed ruling on each issue to be resolved, together
        with a request for a specific damage award or other remedy for
        each issue. The proposed rulings and remedies shall not contain
        any recitation of the facts or any legal arguments and shall not
        exceed one (1) page per issue.
    
        (d)    a brief in support of such party's proposed rulings and
        remedies, provided that the brief shall not exceed twenty (20)
        pages.  This page limitation shall apply regardless of the number
        of issues raised in the ADR proceeding.

    Except as expressly set forth in subparagraphs 4(a) - 4(d), no
    discovery shall be required or permitted by any means, including
    depositions, interrogatories, requests for admissions, or production
    of documents.

5.  The hearing shall be conducted on two (2) consecutive days and shall
    be governed by the following rules:

        (a)    Each party shall be entitled to five (5) hours of hearing
        time to present its case.  The neutral shall determine whether
        each party has had the five (5) hours to which it is entitled.

        (b)    Each party shall be entitled, but not required, to make an
        opening statement, to present regular and rebuttal testimony,
        documents or other evidence, to cross-examine witnesses, and to
        make a closing
                                 (PAGE 25)
               argument.  Cross-examination of witnesses shall occur
        immediately after their direct testimony, and cross-examination
        time shall be charged against the party conducting the
        cross-examination.

        (c)    The party initiating the ADR shall begin the hearing and,
        if it chooses to make an opening statement, shall address not only
        issues it raised but also any issues raised by the responding
        party.  The responding party, if it chooses to make an opening
        statement, also shall address all issues raised in the ADR.
        Thereafter, the presentation of regular and rebuttal testimony and
        documents, other evidence, and closing arguments shall proceed in
        the same sequence.

        (d)    Except when testifying, witnesses shall be excluded from
        the hearing until closing arguments.

        (e)    Settlement negotiations, including any statements made
        therein, shall not be admissible under any circumstances.
        Affidavits prepared for purposes of the ADR hearing also shall not
        be admissible.  As to all other matters, the neutral shall have
        sole discretion regarding the admissibility of any evidence.

6.  Within seven (7) days following completion of the hearing, each party
    may submit to the other party and the neutral a post-hearing brief in
    support of its proposed rulings and remedies, provided that such brief
    shall not contain or discuss any new evidence and shall not exceed ten
    (10) pages.  This page limitation shall apply regardless of the number
    of issues raised in the ADR proceeding.

7.  The neutral shall rule on each disputed issue within fourteen (14)
    days following completion of the hearing.  Such ruling shall adopt in
    its entirety the proposed ruling and remedy of one of the parties on
    each disputed issue but may adopt one party's proposed rulings and
    remedies on some issues and the other party's proposed rulings and
    remedies on other issues.  The neutral shall not issue any written
    opinion or otherwise explain the basis of the ruling.

8.  The neutral shall be paid a reasonable fee plus expenses.  These fees
    and expenses, along with the reasonable legal fees and expenses of the
    prevailing party (including all expert witness fees and expenses), the
    fees and expenses of a court reporter, and any expenses for a hearing
    room, shall be paid as follows:

        (a)    If the neutral rules in favor of one party on all disputed
        issues in the ADR, the losing party shall pay 100% of such fees
        and expenses.
                                 (PAGE 26)
        (b)    If the neutral rules in favor of one party on some issues
        and the other party on other issues, the neutral shall issue with
        the rulings a written determination as to how such fees and
        expenses shall be allocated between the parties.  The neutral
        shall allocate fees and expenses in a way that bears a reasonable
        relationship to the outcome of the ADR, with the party prevailing

          2.4    (a) Taking into account the complexity, and stage of
          development of the PRODUCT and the science related thereto,
          MEDIMMUNE shall select and use reasonable best efforts under the
          circumstances to research, develop and then commercialize a
          selected PRODUCT.  The efforts of a SUBLICENSEE, collaborator

         2.   Phase II clinical trials on any Product initiated by MEDIMMUNE an
            AFFILIATE, or a SUBLICENSEE anywhere in the World by the beginning 
            of the (CONFIDENTIAL TREATMENT HAS BEEN REQUESTED), or two years
            after Milestone 1, whichever is later.
         
         3.   Phase III clinical trials on any Product initiated by MEDIMMUNE an
            AFFILIATE, or a SUBLICENSEE anywhere in the World by the beginning 
            of (CONFIDENTIAL TREATMENT HAS BEEN REQUESTED), or two years after
            Milestone 2, whichever is later.
         
         4.   A product license application submitted by MEDIMMUNE an AFFILIATE,
            or a SUBLICENSEE in any territory of the world by beginning of

            year after Milestone 4, whichever is later.

                 (c) If MEDIMMUNE an AFFILIATE, or a SUBLICENSEE fails to
          achieve a Milestone by the Milestone date, then MEDIMMUNE may
          request a meeting with UNIVERSITY within ten (10) days of the
          Milestone date to discuss the reasons for the failure to meet the
          Milestone, and to propose corrective actions and a revised
          schedule for future milestones.  Within thirty (30) days of the
          Milestone date if the Milestone has not been achieved, as its
          sole and exclusive remedy,
                 UNIVERSITY may give notice that the license granted
          hereunder is no longer exclusive (but only if the failure to
          achieve the milestone was within the control of MEDIMMUNE) or
          agree to a revised schedule of future milestones.

                 reasonable steps to restrict and maintain the
                 confidentiality of the disclosure;

                      (v) is required by law, rule, regulation or bona

          RIGHT  licensed to LICENSEE hereunder in the country where sold;
          or (ii) a royalty of the lesser of (CONFIDENTIAL TREATMENT HAS
          BEEN REQUESTED) of the running royalty received by LICENSEE from
          its SUBLICENSEES for the sale of PRODUCTS or (CONFIDENTIAL
          TREATMENT HAS BEEN REQUESTED) of the NET SALES of PRODUCT sold by
          the SUBLICENSEE.

         (B)  In the event that MEDIMMUNE'S license is converted to a non-

            BEEN REQUESTED).
         
         (C)  In the event that a PRODUCT includes both component(s) covered by 
            a VALID CLAIM of a PATENT RIGHT ("Patented Component(s)") and a

            are also due to UNIVERSITY pursuant to Paragraph 5.1 (such royalties
            to such party are hereinafter "Other Royalties"), then the royalties
            to be paid to UNIVERSITY by MEDIMMUNE pursuant to Paragraph 5.1 (A)
            or (B) shall be reduced by (CONFIDENTIAL TREATMENT HAS BEEN 
            REQUESTED) of the amount of such Other Royalties, but in no event 
            shall any royalities payable under Paragraph 5.1 be reduced by more

         6.1.3.    If within three (3) months after having been notified of any
            alleged infringement, UNIVERSITY shall have been unsuccessful in 
            persuading the alleged infringer to desist and shall not have 
            brought and shall not be diligently prosecuting an infringement 
            action; or if UNIVERSITY shall notify MEDIMMUNE at any time prior 
            thereto of its intention not to bring suit against any alleged 
            infringer, then MEDIMMUNE in its sole discretion shall have the
            right, but shall not be obligated, to either:
         
                 (a)  settle the infringement dispute by sublicensing the 
                    alleged infringer or by other means; or
                 
                 (b)  prosecute at its own expense any infringement of the 
                    PATENT RIGHTS. In the event MEDIMMUNE prosecutes such 
                    infringement, MEDIMMUNE may, for such purposes, request to 
                    use the name of UNIVERSITY as party plaintiff.  Subject to
                    the approval of the Board of Trustees of Loyola University 
                    of Chicago, the UNIVERSITY may agree to become a party 
                    plaintiff.
                 
         6.1.4     In the event that MEDIMMUNE shall undertake the enforcement
            and/or defense of the PATENT RIGHTS by litigation, including any
            declaratory judgment action, MEDIMMUNE may withhold an amount equal
            to up to (CONFIDENTIAL TREATMENT HAS BEEN REQUESTED) from future 
            royalties due under Section 5 of this Agreement for legal expenses,
            including reasonable attorneys' fees, in connection with such 
            litigation. Any recovery of damages by MEDIMMUNE for any such suit 
            shall be applied first to reimburse UNIVERSITY for any royalties due
            but withheld under this paragraph 6.1.4 and any unreimbursed legal
            expenses of UNIVERSITY, and second in satisfaction of any 
            unreimbursed expense and attorney's fees of MEDIMMUNE relating to 
            the suit. The balance remaining from any such recovery shall be
            distributed to MEDIMMUNE, provided that MEDIMMUNE shall pay to 
            UNIVERSITY such royalties as would otherwise be applicable under 
            Section 5 hereof for that portion of MEDIMMUNE's recovery 
            attributable to lost sales.  MEDIMMUNE shall be entitled to settle
            any such litigation by agreement, consent, judgment, voluntary
            dismissal, or otherwise.
         
         6.1.5     MEDIMMUNE shall have the right in accordance with the terms 
            and conditions herein to sublicense any alleged infringer under
                                  (PAGE 9)
         6.1.6     the PATENT RIGHTS for future infringements.
         
         6.1.6    In any infringement suit either party may institute to enforce
            the PATENT RIGHTS pursuant to this Agreement, the other party hereto
            shall, at the request of the party initiating such suit, cooperate 
            in all respects and, to the extent possible, have its employees 
            testify when requested and make available relevant records, papers,
            information, samples, specimens, and the like. All reasonable out-
            of-pocket costs incurred in connection with rendering cooperation
            requested hereunder shall be paid by the party requesting
            cooperation.
         
         6.1.7     Any of the foregoing notwithstanding, if at any time during 
            the term of this Agreement any of the PATENT RIGHTS are declared 
            invalid or unenforceable, by a court of competent jurisdiction or an
            administrative agency from which no appeal can be or is taken, 
            MEDIMMUNE, shall have no further obligation to UNIVERSITY with
            respect to its future use or sale of any product or process covered
            by such PATENT RIGHTS, including the obligation of paying royalties.
            Nevertheless, MEDIMMUNE shall not have a damage claim or a claim for
            refund or reimbursement against the UNIVERSITY.
         
     6.2  Alleged infringement of a third party's patent rights.
     
         6.2.1     In the event that litigation against MEDIMMUNE is initiated 
            by a third-party charging MEDIMMUNE with infringement of a patent of
            the third party as a result of the manufacture, use or sale by 
            MEDIMMUNE of PRODUCT covered by a PATENT RIGHT, MEDIMMUNE shall
            promptly notify UNIVERSITY in writing thereof. MEDIMMUNE's costs as
            to any such defense shall be creditable against any and all payments
            due and payable to UNIVERSITY under Section 5 of this Agreement but,
            no royalty payment after taking into consideration any such credit
            under this Section 6.2.1 shall be reduced by more than 
            (CONFIDENTIAL TREATMENT HAS BEEN REQUESTED) provided, however,
            that if said claim of infringement does not pertain to a PATENT 
            RIGHT of UNIVERSITY, but to other patent rights used in the 
            manufacture or sale of the PRODUCT, then this credit shall  not be 
            made against royalities due and payable to UNIVERSITY.
         
         6.2.2     In the event of a judgment in any suit in which a court of
            competent jurisdiction rules that the manufacture, use or sale by 
            MEDIMMUNE of PRODUCT covered by a PATENT RIGHT has infringed on a 
            third-party's patent requiring MEDIMMUNE to pay damages or a royalty
            to said third party, or in the event of a settlement of such suit
            requiring damages or royalty payments to be made, payments due to
            UNIVERSITY under Section 5 of this Agreement arising from the 
            applicable PRODUCT shall be correspondingly reduced by the amounts
            due under the requirement of such judgment or under the terms of 
            such settlement.  However, subject to Section 5.1(c), the royalty
            payment after taking into consideration any such reduction under
            this Section 6.2.2 shall not be reduced by more than (CONFIDENTIAL
            TREATMENT HAS BEEN REQUESTED);
                                  (PAGE 10)
         6.2.3     provided, however that if said judgment does not
            pertain to a PATENT RIGHT of UNIVERSITY, but to other patent rights
            used in the manufacture or sale of the PRODUCT, then this credit 
            shall not be made against royalties due and payable to the 
            UNIVERSITY.
         
         6.2.3  UNIVERSITY shall give MEDIMMUNE assistance in the defense
            of any such infringement charge or lawsuit, as may be
            reasonably required.

                      (i)  (CONFIDENTIAL TREATMENT HAS BEEN REQUESTED)

                      (ii) (CONFIDENTIAL TREATMENT HAS BEEN REQUESTED)

                      (iii)(CONFIDENTIAL TREATMENT HAS BEEN REQUESTED)

                      (iv) (CONFIDENTIAL TREATMENT HAS BEEN REQUESTED)

                      (v)  (CONFIDENTIAL TREATMENT HAS BEEN REQUESTED)

                      (vi) (CONFIDENTIAL TREATMENT HAS BEEN REQUESTED)

                      (vii)(CONFIDENTIAL TREATMENT HAS BEEN REQUESTED)

     5.3    Liability by SB.

            Except by reason of force majeure as provided in Section 13.1,
in the event that SB fails materially to satisfy its development and/or
marketing obligations under Sections 5.1 and 5.2 with respect to Vaccine
Product in any country of the Major Markets, MEDIMMUNE shall have at its
sole remedy the right and option to terminate this Agreement for the
concerned country of the Major Markets in its sole discretion in accordance
with Section 12.2(a).

     5.4    Reporting.

     SB shall provide to MEDIMMUNE an annual project status report
(including the status of regulatory approvals) of the development, and
registration of each Vaccine Product.  All such reports by SB shall be
treated as Confidential Information of SB and shall be subject to the
restrictions imposed under Section 11.2.

     5.5    MEDIMMUNE shall have the right to terminate this Agreement in
its entirety if

                      (i)  (CONFIDENTIAL TREATMENT HAS BEEN REQUESTED)


6.   FEE; MILESTONE PAYMENTS AND ROYALTIES.

     6.1    (a)  Fee by SB.  In partial consideration of MEDIMMUNE Patents
and MEDIMMUNE Technology resulting from the use of the research performed
by MEDIMMUNE prior to this Agreement and the right to use pre-clinical and
clinical information developed by MEDIMMUNE,  SB shall pay MEDIMMUNE a fee
of (CONFIDENTIAL TREATMENT HAS BEEN REQUESTED) on the Effective Date.  In
addition, SB shall purchase MEDIMMUNE Common Stock from MEDIMMUNE for a
purchase price of (CONFIDENTIAL TREATMENT HAS BEEN REQUESTED) according to
the terms of the Stock Purchase Agreement attached hereto as Schedule D.


                                 (PAGE 13)
            (b)  In further consideration of MEDIMMUNE Patents and
MEDIMMUNE Technology resulting from the use of the research performed by
MEDIMMUNE prior to this Agreement and the right to use preclinical and
clinical information developed by MEDIMMUNE prior to the Agreement and
rights to future developments of the Vaccine Product undertaken by
MEDIMMUNE during the term of the Agreement, SB agrees to provide a
Technology Access Fee to MEDIMMUNE.  Such Technology Access Fee  shall be
(CONFIDENTIAL TREATMENT HAS BEEN REQUESTED).

     (CONFIDENTIAL TREATMENT HAS BEEN REQUESTED).  Upon mutual agreement of
both parties, the above-mentioned payment schedule of the Technology Access
Fee may be accelerated.  In each calendar year, the fee for the year shall
be paid in equal quarterly installments in advance on the first day of
January, April, July and October of each calendar year except the first
payment shall be made on the Effective Date.  All payments shall be sent
via wire transfer to a bank account designated by MEDIMMUNE from time to
time.  In the event that SB has paid (CONFIDENTIAL TREATMENT HAS BEEN
REQUESTED) under this Section 6.1(b), SB will have met its  payment
obligation under this Section 6.1(b).  In the event any portion of this
Technology Access Fee is not timely made, all of the remaining fee shall
become due and payable immediately.

     6.2    Development Milestone Payments by SB.  In partial consideration
of the research performed by MEDIMMUNE prior to this Agreement and the
right to use pre-clinical and clinical information developed by MEDIMMUNE,
SB shall pay MEDIMMUNE the following milestone payments upon the first
occurrence of each event set forth below with respect to the first Vaccine
Product, whether achieved by SB or its Affiliates or its Sublicensees:

            (a)  (CONFIDENTIAL TREATMENT HAS BEEN REQUESTED)

            (b)  (CONFIDENTIAL TREATMENT HAS BEEN REQUESTED)

            (c)  (CONFIDENTIAL TREATMENT HAS BEEN REQUESTED)

            (d)  (CONFIDENTIAL TREATMENT HAS BEEN REQUESTED)

            (e)  (CONFIDENTIAL TREATMENT HAS BEEN REQUESTED)

            (f)  (CONFIDENTIAL TREATMENT HAS BEEN REQUESTED)

            (g)  (CONFIDENTIAL TREATMENT HAS BEEN REQUESTED)

            (i)  (CONFIDENTIAL TREATMENT HAS BEEN REQUESTED)

            (ii) (CONFIDENTIAL TREATMENT HAS BEEN REQUESTED)

            (iii) (CONFIDENTIAL TREATMENT HAS BEEN REQUESTED)

            (iv) (CONFIDENTIAL TREATMENT HAS BEEN REQUESTED)

            (v)  (CONFIDENTIAL TREATMENT HAS BEEN REQUESTED)

                                 (PAGE 14)
     (CONFIDENTIAL TREATMENT HAS BEEN REQUESTED)

     6.3    Royalties.  In partial consideration of the rights and licenses
granted by MEDIMMUNE to SB under this Agreement, during the Royalty Term,
on a country-by-country and Vaccine Product-by Vaccine Product basis, SB
shall pay to MEDIMMUNE a royalty on Net Sales of Vaccine Products in an
amount equal to the following percentages of the specified portions of the
aggregate annual Net Sales of all Vaccine Products sold by SB, its
Affiliates, distributors  and its Sublicensees throughout the Territory:

                     (i)  (CONFIDENTIAL TREATMENT HAS BEEN REQUESTED)

                     (ii) (CONFIDENTIAL TREATMENT HAS BEEN REQUESTED)

                     (iii)(CONFIDENTIAL TREATMENT HAS BEEN REQUESTED)

                     (iv) (CONFIDENTIAL TREATMENT HAS BEEN REQUESTED)

     In calculating the royalty due under this Section with respect to Net
Sales of Vaccine Products during any period of less than a calendar year,
the foregoing thresholds for a calendar year Net Sales shall be pro rated
in accordance with the duration of such period.

     6.4    Third Party Compensation.

            (a)  (CONFIDENTIAL TREATMENT HAS BEEN REQUESTED)

            (b) With respect to any possible future license Agreements
between SB and a Third Party with respect to (CONFIDENTIAL TREATMENT HAS
BEEN REQUESTED) HPV Vaccines, MEDIMMUNE shall notify SB, and SB shall
negotiate such Agreements and decide solely whether such technology is
required.  SB shall pay all royalties and other compensation under any such
Agreement and MEDIMMUNE will not enter into such an Agreement without the
consent of SB.

            (c) For the avoidance of doubt, SB shall not pay any
compensation or royalty for any Third Party Agreement pertaining to an HPV
Vaccine which (1) MEDIMMUNE enters during the Research Term without the
consent of the Steering Committee or (2) which MEDIMMUNE would enter into
after the Research Term.

            (d) In the event that a dispute arises with a Third Party with
respect to the compensation owed to a Third Party under a Third Party
Agreement which is to be paid by SB pursuant to this Section 6.4, the
parties agree to cooperate with each other to reach a fair and equitable
resolution to such dispute.

     6.5    Royalty Reduction.  The royalties payable to MEDIMMUNE by SB
can be reduced only as follows:

                If a Vaccine Product incorporates "Another Vaccine", which
            is not covered by a MEDIMMUNE Patent to form a combination
            product, then an adjusted royalty will be calculated based on
            multiplying the Net Sales of the combination Vaccine Product by
            the quotient 1/1+A, where A equals the total number of "Another
            Vaccine"
                                 (PAGE 15)
                included in the combined product.  In no event shall this
            adjustment cause the royalty to be applied to less than 50% of
            the Net Sales of the combined Vaccine Product.  "Another
            Vaccine" means a distinct proprietary product and does not
            include HPV antigens or adjuvants.

                (CONFIDENTIAL TREATMENT HAS BEEN REQUESTED)


     6.6    Obligation to Pay Royalties. The obligation to pay royalties to
MEDIMMUNE under this Section 6 is imposed only once with respect to the
same unit of Vaccine Product regardless of the number of Patents pertaining
thereto.  SB shall only be entitled to a credit against royalties or a
reduction of the royalty rate once with respect to any Vaccine Product in
any country pursuant to any provision in this Agreement.  There shall be no
obligation to pay royalties to MEDIMMUNE under this Section 6 on sales of
Vaccine Products  among SB and its Affiliates and its Sublicensees, but in
such instances the obligation to pay royalties shall arise upon the sale by
SB, its Affiliates or its Sublicensees to unrelated Third Parties.

     6.7    In addition to all other compensation payable to MEDIMMUNE
under this Section 6, SB shall make a non-creditable minimum annual payment
to MEDIMMUNE of (CONFIDENTIAL TREATMENT HAS BEEN REQUESTED) due and payable
on January 1st of each year after termination of the Research Program and
until filing for regulatory approval for a Vaccine Product at the FDA or
its equivalent in the EU.

7.  REPRESENTATIONS, WARRANTIES AND COVENANTS.

    7.1  Representations and Warranties of Both Parties.  Each Party
represents and warrants to the other Party that, as of the date of this
Agreement:

         (a)     Such Party is duly organized and validly existing under
the laws of the state of its incorporation and has full corporate power and
authority to enter into this Agreement and to carry out the provisions
hereof.

         (b)     The Third Party Agreements represent all rights and
licenses granted to MEDIMMUNE relating to HPV Vaccine which exist on the
Effective Date and MEDIMMUNE has provided SB with a true and  complete copy
of such Third Party Agreements;

         (c)     MEDIMMUNE has not granted rights under MEDIMMUNE
Technology and/or MEDIMMUNE Patents to any Third Party which is in conflict
with the rights granted to SB pursuant to this Agreement.

         (d)     MEDIMMUNE acknowledges that in entering into this
Agreement, SB may have relied upon the technical or clinical information
provided to SB by MEDIMMUNE with respect to an (CONFIDENTIAL TREATMENT HAS
BEEN REQUESTED) Vaccine Product.  MEDIMMUNE has no present knowledge that
any of the technical or clinical information provided to SB by MEDIMMUNE
with respect to an (CONFIDENTIAL TREATMENT HAS BEEN REQUESTED) Vaccine
Product is inaccurate in any material respect.

                                 (PAGE 16)
7.2 EXCEPT WITH RESPECT TO SECTION 2.4(b), MEDIMMUNE MAKES NO OTHER
REPRESENTATION OR WARRANTY HEREUNDER, INCLUDING, BUT NOT LIMITED TO,
WARRANTIES OF MERCHANTABILITY OR FITNESS FOR USE OR WITH RESPECT TO THE
VALIDITY, ENFORCEABILITY, NON-INFRINGEMENT OF MEDIMMUNE PATENTS.

8.   PAYMENTS AND REPORTS.

     8.1    Royalty Payments.  All royalty payments due hereunder shall be
paid quarterly within thirty (30) days of the end of each calendar quarter.
Each such payment shall be accompanied by a statement, Product-by-Product
and country-by-country, of the amount of Gross Sales, the calculation of
Net Sales and the units of Vaccine Product during such quarter, the amount
of royalties due on such Net Sales, the conversion rates used in converting
to United States Dollars and any other information reasonably requested by
MEDIMMUNE to enable MEDIMMUNE to determine amounts it is owed hereunder.
SB shall also provide MEDIMMUNE with a calculation and a report with
respect to royalties paid on behalf of MEDIMMUNE pursuant to Section 6.4.

     8.2    Mode of Payment.  All invoices and statements submitted by
MEDIMMUNE shall be stated in U.S. Dollars.  SB shall make all payments
required under this Agreement as directed by MEDIMMUNE from time to time in
United States Dollars.  Whenever for the purpose of calculating royalties
conversion from any foreign currency shall be required, such conversion
shall be at the average rate of exchange for the applicable calendar
quarter based on the daily rate of exchange  published in the Wall Street
Journal, New York edition, for the applicable calendar quarter.

     8.3    Records Retention.  SB and its Affiliates and its Sublicensees
shall keep complete and accurate records pertaining to the sale of Vaccine
Products in the Territory and covering all transactions from which Net
Sales are derived for a period of three calendar years after the year in
which such sales occurred, and in sufficient detail to permit MEDIMMUNE to
confirm the accuracy of royalty payments due hereunder.

     8.4    Audit Request.  At the request and expense (except as provided
below) of MEDIMMUNE, SB and its Affiliates and its Sublicensees shall
permit an independent, certified public accountant appointed by MEDIMMUNE
and reasonably acceptable to SB, at reasonable times and upon reasonable
notice, to examine those records and all other material documents relating
to or relevant to Net Sales in the possession or control of SB or its
Affiliates or its Sublicensees, for a period of three years after such
royalties have accrued.  Said accountant shall not disclose to MEDIMMUNE
any information other than information relating to said reports, royalties,
and payments.  Results of any such examination shall be made available to
both Parties.  If, as a result of any inspection of the books and records
of SB or its Affiliates or its Sublicensees, it is shown that SB's royalty
payments under this Agreement were less than the amount which should have
been paid, then SB shall make all payments required to be made to eliminate
any discrepancy revealed by said inspection within 45 days after
MEDIMMUNE's demand therefor.  Furthermore, if the royalty payments were
less than the amount which should have been paid by an amount in excess of
5% of the royalty payments actually made during the period in question, SB
shall also reimburse MEDIMMUNE for the cost of such inspection.


                                 (PAGE 17)
     8.5    Taxes.  It is understood that all payments required to be made
to MEDIMMUNE under this Agreement shall be paid by SB from the United
Kingdom and pursuant to the tax treaty, no taxes shall be withheld from any
such payment.  In the event of a change in the treaty or law and in the
event that SB is thereafter required to withhold any tax to the tax or
revenue authorities in any country in the Territory regarding any payment
to MEDIMMUNE due to the laws of such country, such amount shall be deducted
from the royalty or other payment to be made by SB, and SB shall notify
MEDIMMUNE and promptly furnish MEDIMMUNE with copies of any tax certificate
or other documentation evidencing such withholding.  Each Party agrees to
cooperate with the other Party in claiming exemptions from such deductions
or withholdings under any agreement or treaty from time to time in effect.

9.   PATENT PROSECUTION; ENFORCEMENT; INFRINGEMENT.

     9.1    Patent Filing, Maintenance and Prosecution.

            (a)  Representatives of MEDIMMUNE and SB shall discuss in which
countries Patents should be filed, prosecuted and/or maintained.  The
Parties acknowledge and agree that they intend to file, prosecute and
maintain Patents in all major commercial markets where viable patent
protection is available (such countries shall be referred to as "Patent
Countries").  If the laws affecting patent protection or maintenance costs
change in any Patent Country, the Parties shall reassess the need to
continue to file, prosecute and maintain Patents in such country.  If the
Parties determine to discontinue such filing, prosecution and maintenance
in any such country, such country shall no longer be deemed a Patent
Country.

            (b)  MEDIMMUNE or MEDIMMUNE licensors, in the case of MEDIMMUNE
Patents licensed to MEDIMMUNE, shall file, prosecute and maintain MEDIMMUNE
Patents in the Territory through patent counsel selected by MEDIMMUNE  and
MEDIMMUNE, shall consult with and keep SB advised with respect thereto.
MEDIMMUNE shall disclose to SB the complete texts of all such patents and
patent applications filed by MEDIMMUNE or its licensor, as well as all
information received concerning the institution or possible institution of
any interference, opposition, re-examination, reissue, revocation,
nullification or any official proceeding involving any patent licensed
herein anywhere in the Territory.  SB shall have the right to review such
pending applications and other proceedings and make recommendations to
MEDIMMUNE concerning them and their conduct.  MEDIMMUNE agrees to keep SB
promptly and fully informed of the course of patent prosecution or other
proceedings including by providing SB with copies of substantive
communications, search reports and Third Party observations submitted to or
received from patent offices throughout the Territory.  MEDIMMUNE shall
provide such patent consultation to SB at no cost to SB.

            In the event MEDIMMUNE intends to finally abandon any MEDIMMUNE
Patents licensed to SB under this Agreement, it shall notify SB and SB
shall have the right at its own expense to assume responsibility for any
such patent or part of patent.

            At SB's request, MEDIMMUNE and/or its licensors, as the case
may be, shall file an application for a Supplementary Protection
Certificate for MEDIMMUNE Patents.  SB shall provide relevant marketing
authorizations as appropriate.
                                 (PAGE 18)
            (c)  Notwithstanding anything in this Section 9.1, SB may, at
its discretion, elect to discontinue financial support of any MEDIMMUNE
Patent in any Patent Country, provided, however, that prior to taking such
action, SB will notify MEDIMMUNE of its intention at least 60 days prior to
the date on which any payment or action is due.  In any Patent Country in
which SB has elected to discontinue its support of any MEDIMMUNE Patent,
MEDIMMUNE, upon receiving notice, may elect at its own expense to assume
all financial responsibility for the prosecution or maintenance of such
MEDIMMUNE Patent in such Patent Country.  In such event, all SB's rights to
the MEDIMMUNE Patent will be deemed to have expired with respect to such
Patent Country upon MEDIMMUNE's receiving notice of SB's decision.

            (d)  Absent an election not to support the filing, prosecution
and/or maintenance of a Patent in any Patent Country, all costs and
expenses incurred under this Section 11.1 with respect to the filing,
prosecution and/or maintenance of Patents will be paid by SB.  Included in
such costs and expenses are all reasonable costs for the prosecution,
issuance, and maintenance of such patent applications and patents issuing
thereon, and any divisional, continuation-in-part, reissue applications or
patents, patents-in-addition, patents-of-revalidation or the registrations
of any patent or the like.

     9.2    Review of Patent Office Communications.  With respect to any
Patents, each patent application, office action, response to office action,
request for terminal disclaimer, and request for reissue or reexamination
of any patent issuing from any patent application made by either Party
shall be provided to the other Party sufficiently prior to the filing of
such application, response or request to allow for review and comment by
such other Party.  Each Party shall have the right to take any action that
in its judgment is necessary to preserve such Patents.

     9.3    Patent Enforcement.

            (a)  Each Party shall notify the other promptly after such
Party becomes aware of any alleged infringement of any Patent in any
country in the Territory.  If any of the Patents under which SB holds a
license hereunder is infringed by a Third Party, SB shall have the right
and option, but not the obligation, to bring an action for infringement, at
its sole expense, against such Third Party in the name of MEDIMMUNE and/or
in the name of SB, and to join MEDIMMUNE as a party plaintiff if required.
SB shall promptly notify MEDIMMUNE of any such infringement and shall keep
MEDIMMUNE informed as to the prosecution of any action for such
infringement.  SB shall have the full control over the conduct of the
litigation including settlement thereof provided, however, that SB shall
make no decision, including, but not limited to, settlement which adversely
affects the validity or enforceability of the MEDIMMUNE Patents without the
written consent of MEDIMMUNE.  It is understood that in the case of
MEDIMMUNE Patents sublicensed to SB, the rights of this Section 9.3(a) are
subject to the terms and restrictions of the Agreement(s) between MEDIMMUNE
and its licensors.

            (b)  In the event that SB does not institute an infringement
proceeding against an offending Third Party within 90 days after becoming
aware or receiving notice of any alleged infringement, then MEDIMMUNE shall
have the right and option, but not the obligation, to institute such an
                                 (PAGE 19)
action and to retain any recovered damages.

            (c)  In any infringement suit either Party may institute to
enforce any Patents pursuant to this Agreement, the other Party hereto
shall, at the request of the Party initiating such suit, cooperate in all
respects and, to the extent possible, have its employees testify when
requested and make available relevant records, papers, information,
samples, specimens, and the like.  All reasonable out-of-pocket costs
incurred in connection with rendering cooperation requested hereunder shall
be paid by the Party requesting cooperation.

            (d)  The costs and expenses of any action instituted pursuant
to this Section 9.3 (including reasonable fees of attorneys and other
professionals) shall be borne by the Party instituting the action, or, if
the Parties elect to cooperate in instituting and maintaining such action,
such costs and expenses shall be borne by the Parties in such proportions
as they may agree in writing.  Each Party shall execute all necessary and
proper documents and take such actions as shall be appropriate to allow the
other Party to institute and prosecute such infringement actions (if such
other Party has the right to institute and prosecute such infringement
actions pursuant to this Section 9.3).

            (e)  In the event that either Party shall undertake the
enforcement and/or defense of any Patent, any award or compensation
(including the fair market value of non-monetary compensation) paid by
Third Parties as a result of such an infringement action (whether by way of
settlement or otherwise) shall be applied as follows: (i) first, to
reimbursement of each Party for all expenses incurred by each in connection
with such action, on a pro rata basis, and (ii) second, any remaining
balance shall be allocated to the Party undertaking the action, except that
such amount shall be deemed to be Net Sales hereunder, for which MEDIMMUNE
shall be entitled to receive a royalty as provided in this Agreement.

            (f)  SB shall not have the right to settle or compromise any
such action in a manner which adversely affects MEDIMMUNE Patents without
the written consent of MEDIMMUNE.

            (g)  SB at its sole discretion may decide to enter into a
license agreement with any Third Party pertaining to HPV Vaccines in order
to avoid an (alleged) infringement of Third Party patents.  In case both
parties deem it necessary to acquire additional technology, the Steering
Committee will decide on entering into license agreements with Third
Parties.

     9.4    Infringement Actions by Third Parties.  In the event of the
institution of any suit by a Third Party against SB, its Affiliates or its
Sublicensees for patent infringement involving the use, sale, distribution
or marketing of any Vaccine Product in the Territory and such infringement
claim is a result of the use of the MEDIMMUNE Patents or MEDIMMUNE
Technology SB shall promptly notify MEDIMMUNE in writing of such suit.  In
the event of all such actions SB shall defend such action at its own
expense, and MEDIMMUNE hereby agrees to assist and cooperate with SB, at
its own expense, to the extent necessary in the defense of such suit.  SB
shall have the right to settle the suit or consent to an adverse judgment
thereto, in its sole discretion.  During the pendency of such action, all
royalties
                                 (PAGE 20)
due hereunder shall continue to be paid by SB.  SB shall assume full
responsibility for the payment of any award for damages, or any amount due
pursuant to any settlement entered into by SB with such Third Party,
subject to the provisions of this Agreement with respect to the reduction
of royalties.  Any and all damages and awards received by SB as a result
thereof  (i.e., as a result of a counterclaim) shall be allocated between
the Parties in the same manner as provided in Section 9.3.

10.  INDEMNIFICATION.

     10.1   By MEDIMMUNE.  MEDIMMUNE shall indemnify and hold SB, its
Affiliates and its Sublicensees, and each of their respective directors,
officers, employees, shareholders and agents, harmless from and against any
and all Third Party claims, suits or demands for liabilities, damages,
losses, costs and expenses (including the reasonable fees of attorneys and
other professionals) arising out of or resulting from:

                 any breach of a representation or warranty made by
            MEDIMMUNE or negligence, recklessness or wrongful intentional
            acts or omissions of MEDIMMUNE, or its Affiliates and their
            respective directors, officers, employees and agents, in
            connection with the work performed by MEDIMMUNE under the
            Research Program.

     10.2   By SB.  SB shall indemnify and hold MEDIMMUNE and licensors of
MEDIMMUNE to the extent that SB is sublicensed hereunder and its directors,
officers, employees,  shareholders and agents, harmless from and against
any and all Third Party claims, suits or demands for liabilities, damages,
losses, costs and expenses (including the reasonable fees of attorneys and
other professionals) arising out of or resulting from:

            the development manufacture, use, distribution or sale of any
Vaccine Product by SB, its Affiliates, distributors or Sublicensees except
those losses which arise out of the negligence or intentional misconduct of
MEDIMMUNE.

     10.3   Costs of Enforcement.  As the parties intend complete
indemnification, all costs and expenses of enforcing any provision of this
Section 10 shall also be reimbursed by the indemnifying Party.

     10.4   Conditions to Indemnification.  A person or entity that intends
to claim indemnification under this Section (the "Indemnitee") shall
promptly notify the other Party (the "Indemnitor") of any loss, claim,
damage, liability or action in respect of which the Indemnitee intends to
claim such indemnification, and the Indemnitor shall assume the defense
thereof with counsel mutually satisfactory to the Indemnitee whether or not
such claim is rightfully brought; provided, however, that an Indemnitee
shall have the right to retain its own counsel, with the fees and expenses
to be paid by the Indemnitor if Indemnitor does not assume the defense, or
if representation of such Indemnitee by the counsel retained by the
Indemnitor would be inappropriate due to actual or potential differing
interests between such Indemnitee and any other person represented by such
counsel in such proceedings.  The indemnity agreement in  this Section
shall not apply to amounts paid in settlement of any loss, claim, damage,
liability or action if such settlement is effected without the consent of
the Indemnitor, which consent shall not be withheld or delayed
unreasonably.
                                 (PAGE 21)
The failure to deliver notice to the Indemnitor within a reasonable time
after the commencement of any such action, only if prejudicial to its
ability to defend such action, shall relieve such Indemnitor of any
liability to the Indemnitee under this Section, but the omission so to
deliver notice to the Indemnitor will not relieve it of any liability that
it may have to any Indemnitee otherwise than under this Section.   The
Indemnitee under this Section, its employees and agents, shall cooperate
fully with the Indemnitor and its legal representatives in the
investigations of any action, claim or liability covered by this
indemnification.

     10.5   Any and all Sublicensees of SB shall agree to the same
indemnity as in Section 10.2 of this Agreement and MEDIMMUNE shall be made
a Third Party beneficiary therein.

11.  PUBLICATION; CONFIDENTIALITY.

     11.1   Publication.

            (a)  Both Parties recognize that each may wish to publish the
results of their work relating to the Research Program.  However, both
Parties also recognize the importance of acquiring patent protection on
inventions prior to publication.  Consequently, neither Party shall publish
or present the results of the Research Program with respect to any Vaccine
Product or of development studies without the permission of the Steering
Committee.  If the Steering Committee is not in existence, the Parties
shall appoint appropriate representatives for this function.  This Section
11.1(a) shall cease to apply with respect to any Vaccine Product upon the
commercial launch of such Vaccine Product.

            (b)  Each Party also agrees to delete from any such proposed
publication any technical or scientific Confidential Information of the
other Party upon such other Party's reasonable request.

            (c)  In any publication permitted under this Section 11.1, each
Party shall acknowledge its collaboration with the other Party under this
Agreement.

            (d)  Nothing in Section 11.1 shall prevent MEDIMMUNE: (i) in
connection with efforts to secure financing at any time during the term of
this Agreement, from issuing statements as to achievements made, and the
status of the work being done by the Parties, under this Agreement, so long
as such statements do not jeopardize the ability to obtain patent
protection on Inventions or disclose non-public technical or scientific
Confidential Information of SB; or (ii) from issuing statements that
MEDIMMUNE determines to be necessary, in the opinion of its external
counsel, to comply with applicable law (including the disclosure
requirements of the U.S. Securities and Exchange Commission, Nasdaq or any
other stock exchange on which securities issued by MEDIMMUNE are traded);
provided that MEDIMMUNE shall provide SB with a copy of the proposed text
of such statements sufficiently in advance of the scheduled release thereof
to afford SB a reasonable opportunity to review and comment upon the
proposed text.

     11.2   Confidentiality; Exceptions.

                                 (PAGE 22)
     Except to the extent expressly authorized by this Agreement or
otherwise agreed in writing, the Parties agree that, the receiving Party,
its Affiliates and its Sublicensees, if any, shall use reasonable efforts
to keep, and  to ensure that their officers and directors keep, completely
confidential and shall not publish or otherwise disclose and shall not use
for any purpose any information furnished to it by the other Party, its
Affiliates or its Sublicensees, if any, or developed under or in connection
with the Research Program pursuant to this Agreement, except to the extent
that it can be established by the receiving Party by competent proof that
such information: (i) is or hereafter becomes generally available to the
public other than by reason of any default by the receiving Party with
respect to its confidentiality obligations hereunder; (ii) was already
known to the recipient as evidenced by prior written documents in its
possession; (iii) is disclosed to the recipient by a Third Party who is not
in default of any confidentiality obligation to the disclosing Party; or
(iv) is independently developed by or for the receiving Party without
reference to or reliance upon the information furnished by the other Party
("Confidential Information").  Information disclosed by one Party to the
other shall remain the property of the disclosing Party.

     11.3   Exclusions to Confidentiality.  The restrictions contained in
Section 11.2 shall not apply to Confidential Information that (i) is
submitted by the recipient to governmental authorities to facilitate the
issuance of marketing approvals for a Vaccine Product, provided that
reasonable measures shall be taken to assure confidential treatment of such
information, if practicable; (ii) is provided by the recipient to Third
Parties under appropriate terms and conditions, including confidentiality
provisions equivalent to those in this Agreement, for consulting,
manufacturing, development, manufacturing, external testing, marketing
trials and sublicensing or potential sublicensing of Vaccine Product in
accordance with this Agreement; or (iii) is otherwise required to be
disclosed in compliance with applicable laws or regulations (including,
without limitation, to comply with SEC, Nasdaq or stock exchange disclosure
requirements) or order by a court or other regulatory body having competent
jurisdiction; provided that if a Party is required to make any such
disclosure of the other Party's Confidential Information it will, except
where impracticable for necessary disclosures, for example to physicians
conducting studies or to health authorities, give reasonable advance notice
to the other Party of such disclosure requirement and, except to the extent
inappropriate in the case of patent applications or otherwise, will use its
reasonable best efforts to secure confidential treatment of such
Confidential Information required to be disclosed.

     11.4   Injunctive Relief.  The Parties acknowledge that money damages
alone would not adequately compensate the disclosing Party in the event of
a breach by the receiving Party of this Section 11, and that, in addition
to all other remedies available to the disclosing Party at law or in
equity, it shall be entitled to seek injunctive relief for the enforcement
of its rights under this Section 11.

     11.5   The obligations of this Article 11 shall terminate
(CONFIDENTIAL TREATMENT HAS BEEN REQUESTED) years after the termination of
this Agreement.

12.  TERM; TERMINATION.

                                 (PAGE 23)
     12.1   Term.  This Agreement shall commence as of the Effective Date
and, unless sooner terminated as provided hereunder, shall expire as
follows:

            (a)  As to each Vaccine Product in each country in the
Territory, this Agreement shall expire upon the expiration of the Royalty
Term with respect to such Vaccine Product in such country.

            (b)  This Agreement shall expire in its entirety upon the
termination of the Royalty Term with respect to all Vaccine Products in all
countries in the Territory.

     12.2   Breach.

            (a)  Failure by either Party to comply with any of its material
obligations contained in this Agreement shall entitle the other Party to
give to the Party in default notice specifying the nature of the default
and requiring it to cure such default.  If such default is not cured within
60 days (30 days in the event of a default with respect to an obligation to
pay money) after the receipt of such notice (or, if such default cannot be
cured within such 60-day period, if the Party in default does not commence
and diligently continue actions to cure such default, the Parties agreeing
that all defaults with respect to obligations to pay money shall be curable
within the 30-day period provided above), subject to the provisions of
Sections 4.8 and 5.3, the notifying Party shall be entitled, without
prejudice to any of its other rights conferred on it by this Agreement, and
in addition to any other remedies available to it by law or in equity, to
terminate this Agreement in its entirety, by giving written notice to take
effect immediately upon delivery of such notice.  The right of either Party
to terminate this Agreement, as provided in this Section 12.2, shall not be
affected in any way by its waiver or failure to take action with respect to
any previous default.

            (b)  An election of remedy by a Party for a material breach of
this Agreement under this Section 12.2 on one occasion shall not constitute
a waiver as to any other remedy that may be available to such Party under
this Section 12.2 as to any material breach on another occasion.

            (c)  After Phase II is completed, , SB may terminate this
Agreement by giving sixty (60) days' written notice to MEDIMMUNE but only
if (i) further development and commercialization of Vaccine Product is not
economically feasible or (ii) the technical and clinical information
indicates that there are material concerns about the safety or efficacy of
the Vaccine Product.

            (c)  (CONFIDENTIAL TREATMENT HAS BEEN REQUESTED)

            (d)  (CONFIDENTIAL TREATMENT HAS BEEN REQUESTED)

     12.4   Either party may terminate this Agreement, if, at any time, the
other party shall file in any court or agency pursuant to any statute or
regulation of a country in the Territory a petition of bankruptcy or
insolvency or for reorganization or for an arrangement or for the
appointment of a receiver of trustee of the party or of its assets or if
the other party proposes a written agreement of composition or extension of
its debts or if the other party shall be served with an involuntary
petition against it, filed in any insolvency proceeding, and such petition
shall not be dismissed within 60 days after filing thereof, or if the other
party shall make an assignment for the benefit of its creditors.
Notwithstanding the bankruptcy of MEDIMMUNE or the impairment of
performance of MEDIMMUNE of its obligations under this section, SB shall be
entitled to retain the licenses granted herein, provided it continues to
comply with its obligations to MEDIMMUNE hereunder.

     12.5   Right to Sell Stock on Hand.  Upon the termination of any
rights granted hereunder, in whole or in part as to any Vaccine Product in
any country in the Territory, for any reason other than a failure to cure a
material breach of this Agreement by SB, SB shall have the right to dispose
of all Vaccine Product then on hand to which such termination applies, and
the royalties shall be paid to MEDIMMUNE with respect to such Vaccine
Product as though such rights had not terminated.

     12.6   Accrued Rights, Surviving Obligations.

            (a)  Termination, relinquishment or expiration of this
Agreement for any reason shall be without prejudice to any rights which
shall have accrued to the benefit of either Party prior to such
termination, relinquishment or expiration.  Such termination,
relinquishment or expiration shall not relieve either Party from
obligations which are expressly indicated to survive termination or
expiration of this Agreement.

            (b)  Termination, relinquishment or expiration of this
Agreement shall not terminate SB's obligation to pay all royalties and
milestone payments that shall have accrued prior to such termination.  All
of the Parties' rights and obligations under Sections 2.2(b), 8.4 10, 11,
12.3 12.4, 12.5, 12.6, 14.11 and 14.17 shall survive termination,
relinquishment or expiration hereof.

     12.7   Termination for Failure of Condition.   Either Party may
terminate this Agreement by providing written notice to the other in the
event that Effective Date has not occurred by June 30, 1998.

13.  FORCE MAJEURE.

     13.1   Events of Force Majeure.  Except for payments due under this
Agreement, neither Party shall be held liable or responsible to the other
Party nor be deemed to be in default under or in breach of any provision of
this Agreement for failure or delay in fulfilling or performing any
obligation of this Agreement when such failure or delay is due to force
majeure, and without the fault or negligence of the Party so failing or
                                 (PAGE 25)
delaying. For purposes of this Agreement, force majeure is defined as
causes beyond the control of the Party, including, without limitation, acts
of God; acts, regulations, or laws of any government; war; civil commotion;
destruction of production facilities or materials by fire, flood,
earthquake, explosion or storm; labor disturbances; epidemic; and failure
of pubic utilities or common carriers.  In such event SB or MEDIMMUNE, as
the case may be, shall immediately notify the other Party of such inability
and of the period for which such inability is expected to continue.  The
Party giving such notice shall thereupon be excused from such of its
obligations under this Agreement as it is thereby disabled from performing
for so long as it is so disabled and the 30 days thereafter.  To the extent
possible, each Party shall use reasonable efforts to minimize the duration
of any force majeure.

14.  MISCELLANEOUS.

     14.1   Relationship of Parties.  Nothing in this Agreement is intended
or shall be deemed to constitute a partnership, agency, employer-employee
or joint venture relationship between the Parties.  No Party shall incur
any debts or make any commitments for the other, except to the extent, if
at all, specifically provided herein.

     14.2   Assignment.  (CONFIDENTIAL TREATMENT HAS BEEN REQUESTED)

     14.3   Further Actions.  Each Party agrees to execute, acknowledge and
deliver such further instruments, and to do all such other acts, as may be
necessary or appropriate in order to carry out the purposes and intent of
this Agreement.

     14.4   Notice.  Any notice or request required or permitted to be
given under or in connection with this Agreement shall be deemed to have
been sufficiently given if in writing and personally delivered or sent by
certified mail (return receipt requested), facsimile transmission (receipt
verified), or overnight express courier service (signature required),
prepaid, to the Party for which such notice is intended, at the address set
forth for such Party below:
            (a)  In the case of SB, to:

or to such other address for such Party as it shall have specified by like
notice to the other Party, provided that notices of a change of address
shall be effective only upon receipt thereof.  If delivered personally or
by
                                 (PAGE 26)
facsimile transmission, the date of delivery shall be deemed to be the date

courier service, the date of delivery shall be deemed to be the next
business day after such notice or request was deposited with such service.
If sent by certified mail, the date of delivery shall be deemed to be the
third business day after such notice or request was deposited with the U.S.

name or other designation of the other Party or any other trade name or
trademark of the other Party for any purpose in connection with the

     14.6   Public Announcements.  Except as required by law (including,
without limitation, disclosure requirements of the U.S. Securities and
Exchange Commission, Nasdaq or any other stock exchange on which securities
issued by MEDIMMUNE are traded), neither Party shall make any public
announcement concerning this Agreement or the subject matter hereof without
the prior written consent of the other, which shall not be unreasonably
withheld.  It shall not be unreasonable for a Party to withhold consent
with respect to any public announcement containing any of such Party's
Confidential Information.  In the event of a required public announcement,
to the extent practicable under the circumstances, the Party making such
announcement shall provide the other Party with a copy of the proposed text
prior to such announcement sufficiently in advance of the scheduled release
of such announcement to afford such other Party a reasonable opportunity to
review and comment upon the proposed text.

     14.7   Waiver.  A waiver by either Party of any of the terms and
conditions of this Agreement in any instance shall not be deemed or
construed to be a waiver of such term or condition for the future, or of
any subsequent breach hereof.  All rights, remedies, undertakings,
obligations and agreements contained in this Agreement shall be cumulative
and none of them shall be in limitation of any other remedy, right,
undertaking, obligation or agreement of either Party.

     14.8   Compliance with Law.  Nothing in this Agreement shall be deemed
to permit a Party to export, reexport or otherwise transfer any Vaccine
Product sold under this Agreement without compliance with applicable laws.

     14.9   Severability.  When possible, each provision of this Agreement
will be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Agreement is held to be
prohibited by or invalid under applicable law, such provision will be
ineffective only to the extent of such prohibition or invalidity, without
invalidating the remainder of this Agreement and the parties shall
negotiate, in good faith, a new provision which will, as closely as
possible, carry out the intentions of the parties provided for in the
invalidated provision.

     14.10  Amendment.  No amendment, modification or supplement of any
provisions of this Agreement shall be valid or effective unless made in
writing and signed by a duly authorized officer of each Party.

     14.11  Governing Law.  This Agreement shall be governed by and
interpreted in accordance with the laws of the State of Maryland without
regard to its choice of law principles.  In the event that either Party
desires to initiate litigation with respect to this Agreement, such
litigation shall be conducted in an appropriate court in the State of
Maryland and each Party hereby submits to the jurisdiction of such court(s)
and agrees that venue is proper in such court(s).

     14.12  Entire Agreement.  This Agreement, together with the Exhibits
hereto and every Annual Research Plan approved by the Steering Committee,
sets forth the entire agreement and understanding between the Parties as to
the subject matter hereof and merges all prior discussions and negotiations
between them, and neither of the Parties shall be bound by any conditions,
definitions, warranties, understandings or representations with respect to
such subject matter other than as expressly provided herein or as duly set
forth on or subsequent to the date hereof in writing and signed by a proper
and duly authorized officer or representative of the Party to be bound
thereby.
