GENERAL

         Alkermes, Inc. (together with its subsidiaries, referred to as "we",
"us" or the "Registrant"), a Pennsylvania corporation organized in 1987, is
applying the tools of biotechnology to the development of sophisticated
proprietary drug delivery systems. We are developing product candidates based on
our independent drug delivery technologies: (i) controlled, sustained release of
injectable drugs lasting several days to several weeks, utilizing our
ProLease(R) and Medisorb(R) technologies; (ii) the delivery of drugs into the
brain past the blood-brain barrier, utilizing the Cereport(TM) technology; (iii)
oral delivery of drugs using our RingCap(TM) and dose sipping technologies
("DST"); and (iv) the development of pharmaceutical products based on
proprietary pulmonary drug delivery technologies utilizing our Advanced
Inhalation Research, Inc. ("AIR(TM)") technology. Utilizing these drug delivery
systems, we are currently in various stages of preclinical and clinical
development of several product candidates.

OVERVIEW OF DRUG DELIVERY

         Drug delivery companies apply proprietary technologies to create new
pharmaceutical products based on drugs developed by others. These products are
generally novel, cost-effective dosage forms that provide any of several
benefits including control of drug concentration in the blood, improved safety
and efficacy, improved patient compliance and ease of use and expanded
indications. Drug delivery technologies can provide pharmaceutical companies
with a means of developing new products, as well as expanding existing drug
franchises.

         The drug delivery industry emerged to address the opportunities for
improved delivery of traditional pharmaceutical compounds. These compounds are
generally stable, small molecules manufactured by conventional synthetic
methods, for which oral or transdermal (through the skin) delivery could be
enabled or enhanced by drug delivery technologies. Technologies such as passive
transdermal systems (patches) and improved tablets and capsules have been
developed and successfully applied to a range of pharmaceutical products. In
addition, certain traditional small molecule pharmaceuticals are delivered by
means of encapsulation in polymeric microspheres.

         With the advent of biotechnology, new opportunities in drug delivery
have arisen. Advances in biotechnology have facilitated the development of a new
generation of biopharmaceutical products based on proteins, peptides and nucleic
acids. At the same time, the scientific tools of biotechnology have enabled new
approaches to drug delivery based on exploiting particular biological phenomena,
for example utilizing natural properties of the blood-brain barrier to
facilitate drug delivery to the central nervous system.


                                       2
<PAGE>   3
         Proteins and peptides present drug delivery challenges because they are
often large molecules which degrade rapidly in the bloodstream, have limited
ability to cross cell membranes and generally cannot be delivered orally. As a
result, many biopharmaceuticals must be administered by injection, often
multiple times per day or per week. Consequently, the methods of administration
of biopharmaceuticals can limit their clinical applications to certain disease
states that warrant the expense and inconvenience of frequent injection.

         Drug delivery to the central nervous system is complicated by the
existence of the blood-brain barrier, the layer of tightly joined endothelial
cells which comprise the walls of the capillaries of the brain and limit the
free flow of many blood constituents into the brain. Many drugs cannot easily
cross the blood-brain barrier, and therefore must be administered in relatively
high doses that may result in systemic toxicity or high cost. Drugs with limited
ability to cross the blood-brain barrier include many water soluble
chemotherapeutic and anti-infective agents that are frequently used in the
treatment of diseases outside of the central nervous system.

         Delivery of drugs via the lungs or by oral administration also presents
challenges. The effectiveness of pulmonary dosage forms is often limited by the
poor efficiency of pulmonary devices and the difficulty of administering high
doses of certain drugs. In addition, drugs that act systemically require
deposition in the deep lung, which can lead to the use of complicated and
expensive devices. For certain oral medications, high doses of the drug are
often necessary, requiring patients to swallow numerous large pills. In
addition, many patients have difficulty swallowing pills. Often it is necessary
to take a number of doses per day, which lowers patient compliance and may
cause certain side effects associated with high drug concentrations in the
blood.

BUSINESS STRATEGY

         Our business strategy is to develop and acquire drug delivery systems
to address significant new drug delivery opportunities arising in the
pharmaceutical industry. There are four key elements to our strategy:

         Develop and Acquire Broadly Applicable Drug Delivery Systems and Apply
Them to Multiple Pharmaceutical Products. We develop or acquire drug delivery
systems that have the potential to be applied to multiple proteins, peptides and
small molecule pharmaceutical compounds to create new product opportunities. For
example, we have developed the Cereport technology independently and acquired
the ProLease, Medisorb, AIR, DST and RingCap technologies. We currently have
several product candidates utilizing these technologies in development.

         Collaborate to Develop and Finance Product Candidates. In addition to
conducting product development activities on our own, we have entered into
collaborations with pharmaceutical and biotechnology companies and others to
develop product candidates incorporating our technologies, to provide capital
for product development independent of capital markets and to share development
risk. Currently, we are collaborating with major pharmaceutical companies,
including ALZA Corporation ("ALZA"), Genentech, Inc. ("Genentech"), Johnson &
Johnson and Janssen Pharmaceutica International ("Janssen").

         Apply Drug Delivery Systems to Both Approved Drugs and Drugs in
Development. We are applying our drug delivery technologies to novel
applications and formulations of pharmaceutical products that have already been
approved by the Food and Drug Administration ("FDA") or other


                                       3
<PAGE>   4
regulatory authorities. In such cases, we and our partners can develop a novel
dosage form or application with the knowledge of a drug's safety and efficacy
profile and a body of clinical experience from which to draw information for the
design of clinical trials and for regulatory submissions. We are also applying
our technologies to pharmaceuticals that require a sustained release delivery
system for successful development.

         Establish Independent Product Development Capabilities. We have
assembled our own product development organization to enable us to develop
product candidates for ourselves and our collaborators based on our drug
delivery technologies. This capability gives us flexibility in structuring
development programs and the ability to conduct both feasibility studies and
clinical development programs for ourselves and our collaborators. For example,
we have developed Cereport independently and are conducting all of the clinical
trials of Nutropin Depot(TM) (ProLease recombinant human growth hormone
("rhGH")) for Genentech. In addition, we are developing two proprietary product
candidates utilizing our AIR technology.

DRUG DELIVERY TECHNOLOGY

         Our current focus is on the development of broadly applicable drug
delivery technologies addressing several important drug delivery opportunities,
including injectable sustained release of proteins, peptides and small molecule
pharmaceutical compounds, the pulmonary delivery of both small molecules and
proteins and peptides, drug delivery to the brain across the blood-brain
barrier, and oral drug delivery systems.

         ProLease: injectable sustained release of fragile proteins and peptides

         ProLease is our proprietary technology for the stabilization and
encapsulation of fragile proteins and peptides in microspheres made of common
medical polymers. Our proprietary expertise in this field lies in our ability to
preserve the biological activity of fragile drugs over an extended period of
time and to manufacture these formulations using components and processes
believed to be suitable for human pharmaceutical use. ProLease is designed to
enable novel formulations of proteins and peptides by replacing frequent
injections with controlled, sustained release over time. We believe ProLease
formulations have the potential to improve patient compliance and ease of use by
reducing the need for frequent self-injection, to lower costs by reducing the
need for frequent office visits and to improve safety and efficacy by reducing
both the variability in drug levels inherent in frequent injections and the
aggregate amount of drug given over the course of therapy. In addition, ProLease
may provide access to important new markets currently inaccessible to drugs that
require frequent injections or are administered orally.

         The ProLease formulation process has been designed to assure stability
of fragile compounds during the manufacturing process, during storage and
throughout the release phase in the body. The formulation and manufacturing
process consists of two basic steps. First, the drug is formulated with
stabilizing agents and dried to create a fine powder. Second, the powder is
microencapsulated at very low temperatures. Incorporation of the drug substance
as a stabilized solid under very low temperatures is critical to protecting
fragile molecules from degradation during the manufacturing process and is a key
element of the ProLease technology. The microspheres are suspended in a small
volume of liquid prior to administration to a patient by injection under the
skin or into a muscle. We believe drug release from the ProLease drug delivery
system can be controlled to last from a few days to several months.


                                       4
<PAGE>   5
         Drug release from the microsphere is controlled by diffusion of the
drug through the microsphere and by biodegradation of the polymer. These
processes can be modulated through a number of formulation and fabrication
variables, including drug substance and microsphere particle sizing and choice
of polymers and excipients.

         Our experience with the application of ProLease to a wide range of
proteins and peptides has shown that high incorporation efficiencies and high
drug loads can be achieved. Proteins and peptides incorporated into ProLease
microspheres have maintained their integrity, stability and biological activity
for up to 30 days in in vitro experiments conducted on formulations manufactured
at the preclinical, clinical trial and commercial scale.

         Medisorb: injectable sustained release of traditional small molecule
         pharmaceuticals

         Medisorb is a proprietary technology for encapsulating traditional
small molecule pharmaceuticals in microspheres made of common medical polymers.
Like ProLease, Medisorb is designed to enable novel formulations of
pharmaceuticals by providing controlled, sustained release over time. We believe
Medisorb is suitable for encapsulating stable, water soluble, small molecule
pharmaceuticals at a large scale. We believe that Medisorb formulations may have
superior features of safety, efficacy, compliance and ease of use for drugs
currently administered by frequent injection or administered orally. Drug
release from the microsphere is controlled by diffusion of the pharmaceutical
through the microsphere and by biodegradation of the polymer. These processes
can be modulated through a number of formulation and fabrication variables,
including drug substance and microsphere particle sizing and choice of polymers
and excipients.

         The Medisorb drug delivery system uses manufacturing processes
different from the ProLease manufacturing process. The formulation and
manufacturing process consists of three basic steps. First, the drug is combined
with a polymer solution. Second, the drug/polymer solution is mixed in water to
form liquid microspheres (an emulsion). Third, the liquid microspheres are dried
to produce finished product. The microspheres are suspended in a small volume of
liquid prior to administration to a patient by injection under the skin or into
a muscle. We believe drug release from the Medisorb system can be controlled to
last from a few days to several months.

         Cereport: drug delivery across the blood-brain barrier

         Cereport, a member of a family of Receptor-Mediated Permeabilizers(TM)
("RMPs(TM)"), is a nine amino acid peptide based on bradykinin, a compound
occurring naturally in the body and known to affect vascular permeability.
Cereport is a proprietary, synthetic analog of bradykinin developed by us to
increase transiently the permeability of the blood-brain barrier. Following
injection, Cereport increases permeability by triggering a brief relaxation of
the tight cellular junctions of the blood-brain barrier. During the time the
tight junctions are relaxed, permeability is increased and drug molecules in the
bloodstream can diffuse into the brain in concentrations greater than can
usually be achieved without Cereport. Preclinical and clinical data also suggest
that Cereport increases the uptake of pharmaceuticals in the region of brain
tumor and other pathology.

         Cereport exerts a pharmacologic effect on the vasculature of the brain
and does not itself bind to or serve as a carrier for the drug of which it is
facilitating delivery. We are developing Cereport to be manufactured, packaged
and dispensed as a standalone product. In the clinical setting, Cereport is
administered in conjunction with the therapeutic or diagnostic agent. Timing of
Cereport administration


                                       5
<PAGE>   6
relative to that of the therapeutic or diagnostic agent is determined on a
drug-by-drug basis to optimize barrier permeability during the time of peak drug
plasma concentrations.

         Cereport is intended to be marketed as an independent agent to increase
the utility of other therapeutic and diagnostic compounds given with it. We
believe Cereport may be administered along with cancer chemotherapeutic and
anti-infective agents not currently used in the treatment of central nervous
system disorders because of their limited ability to penetrate the blood-brain
barrier.

         AIR: pulmonary drug delivery

         The AIR technology is our proprietary pulmonary delivery system that
enables the delivery of both small molecules and macromolecules to the lungs.
Our proprietary technology allows us to formulate drugs into dry powders made up
of highly porous particles with low mass density. These particles can be
efficiently delivered to the deep lung by a small, simple inhaler. The AIR
technology is useful for small molecules, proteins or peptides and allows for
both local delivery to the lungs and systemic delivery via the lungs.

         AIR particles can be aerosolized and inhaled efficiently with simple
inhaler devices because low forces of cohesion allow the particles to
deaggregate easily. AIR is developing a family of relatively inexpensive,
compact, easy to use inhalers. The AIR devices are breath activated and made
from injection molded plastic. The powders are designed to quickly discharge
from the device over a range of inhalation flow rates, which may lead to low
patient-to-patient variability and high lung deposition of the inhaled dose. By
varying the ratio and type of excipients used in the formulation, we can deliver
a range of drugs from the device that may provide both immediate and sustained
release.

         DST (Dose Sipping Technology) and RingCap(TM): oral drug delivery
         systems

              Dose Sipping Technology

         DST provides a convenient, simple way to administer medication to
patients who have difficulty swallowing tablets or capsules, such as children
and the elderly. This proprietary system works by putting a granulated form of a
drug in a specially designed straw. As the patient draws fluid through the
disposable straw, the drug mixes with the fluid and the patient receives a
precise dose of the drug. The system can be used with a wide variety of drugs in
a granulated form. We manufacture the DST system using specially designed
machinery and granulated drug provided by our collaborative partners.

              RingCap

         RingCap is a controlled release tablet dosage form which is designed to
reduce the number of times per day that oral drugs must be taken. The RingCap
system is unlike currently available controlled release tablets, which generally
release decreasing amounts of a drug over time. Instead, RingCap is designed to
deliver the total dose evenly over an extended period. The system works by
imprinting the tablet with a series of insoluble rings made of polymers, which
then control the erosion rate of a drug tablet in the gastrointestinal tract. By
varying the number, width and placement of the bands on the tablets, we can
change the release profile of the drug. We believe RingCap may provide a
cost-effective way to manufacture controlled release tablets.

PROLEASE

         Product Development Strategy. Our strategy is to generate multiple
product opportunities by applying ProLease technology to the development of
superior formulations of proteins and peptides that we believe address
significant market opportunities. We believe these formulations have the
potential to expand the utilization of these products and improve the
competitive advantage of our collaborators in major markets.

         The product development plan for individual ProLease formulations is
expected to proceed in several stages. First, we, either on our own or pursuant
to a collaboration, conduct initial feasibility work to test various ProLease
formulations for a particular drug in vitro and in vivo. Second, following the
successful completion of the feasibility stage, preclinical development and
manufacturing scale-up activities directed toward the initiation of clinical
trials of the ProLease formulation would be conducted in collaboration with a
partner. See "Collaborative Arrangements."

         ProLease Recombinant Human Growth Hormone. We are developing a ProLease
formulation of Genentech's rhGH, known as Nutropin Depot, in collaboration with
Genentech. Growth hormone deficiency ("GHD") results in short stature and
potentially other developmental defects. Genentech is the leading supplier of
rhGH in the United States. rhGH is approved for use in the treatment of children
with growth hormone deficiency, Turner's syndrome, chronic renal insufficiency
and other indications and is being tested in additional indications in adults.
rhGH is currently administered frequently, often daily, by subcutaneous
injection.

         On June 28, 1999 our collaborator Genentech submitted an NDA to the
FDA for Nutropin Depot for the treatment of children with GHD. In September
1998, we completed a Phase III clinical trial of ProLease rhGH in 74 growth
hormone deficient children at 27 sites in the United States. The Phase III trial
was designed to test the efficacy, safety and tolerability of Nutropin Depot in
the treatment of children with GHD who had not received any previous treatment
with growth hormone. The study evaluated two dosing regimens of Nutropin Depot,
once a month and twice a month, with both groups receiving the same total dose.

         There can be no assurance that the FDA will accept the NDA for review
or that Nutropin Depot will be approved in a timely manner, if at all. Any
significant delay or non-approval of the NDA would have a material adverse
effect on our business and financial position.

         ProLease Erythropoietin. We are developing a ProLease formulation of
erythropoietin ("EPO") with Johnson & Johnson. EPO is a naturally occurring
protein that stimulates the production of red blood cells. In November 1998,
Johnson & Johnson completed a first probative human study of ProLease EPO.
Following this probative study in human volunteers, both parties agreed to
proceed with the development of an appropriate formulation of ProLease EPO. The
product development program was announced in January 1998 following the
completion of a feasibility study in September 1997. Johnson & Johnson is
conducting the clinical studies for the ProLease EPO program and will be
responsible for further clinical development, if any.

         Additional ProLease Formulations. We continue to develop Prolease
formulations of other unspecified compounds pursuant to feasibility agreements
with several pharmaceutical and biotechnology companies.

MEDISORB

         Product Development Strategy. Our strategy is to generate multiple
product opportunities by applying Medisorb technology to the development of
superior formulations of small molecule pharmaceutical products. We believe
these formulations have the potential to expand the utilization of these
products and improve the competitive advantage of our collaborators in major
markets.

         The product development plan for individual Medisorb formulations is
expected to proceed in several stages. First, we, either on our own or pursuant
to a collaboration, conduct initial feasibility work to test various Medisorb
formulations for a particular drug in vitro and in vivo. Following the
successful completion of the feasibility stage, preclinical development and
manufacturing scale-up activities directed toward the initiation of clinical
trials of the Medisorb formulation would be conducted in collaboration with a
partner. See "Collaborative Arrangements."

         RISPERDAL. We are developing and manufacturing a Medisorb formulation
of Janssen's anti-psychotic drug RISPERDAL. Janssen is an affiliate of Johnson &
Johnson. In April 1999, Janssen announced its intention to proceed with a Phase
III clinical trial of RISPERDAL, after completing Phase I and Phase II clinical
trials. In addition, we have completed scale-up and Phase III manufacturing
activities at the expected commercial scale. We will manufacture the Medisorb
formulation of RISPERDAL for both the clinical trials and commercial sales, if
any. Janssen is responsible for conducting all clinical trials.

CEREPORT

         Product Development Strategy. Our strategy to date has been to advance
Cereport through clinical trials while establishing its safety, permeability
effects in humans and efficacy when used in combination with other drugs. To
support the clinical development of Cereport, we formed and transferred
substantially all of our rights to Cereport technology to Alkermes Clinical
Partners, L.P. (the "Partnership"), which completed a $46 million unit offering
in April 1992. We have the option to purchase all of the limited partnership
interests in the Partnership. As of September 30, 1997, we entered into an
agreement with ALZA relating to the development and commercialization of
Cereport. Under the terms of the agreement, ALZA made an upfront payment of
$10.0 million to Alkermes to fund clinical development in return for an option
to obtain exclusive worldwide commercialization rights to Cereport, subject to
the rights of the Partnership. See "Collaborative Arrangements--Alkermes
Clinical Partners, L.P." and "Collaborative Arrangements--ALZA Corporation."

         Cereport has the potential to be used in combination with a variety of
agents in various disease settings. Our goal is to expand the applications of
Cereport through our own development activities and, when appropriate,
collaborations with pharmaceutical companies, subject to any commercialization
rights of ALZA. We may collaborate with companies having drugs whose uses could
be expanded to include central nervous system indications. In such cases, we and
our partner could collaborate in the clinical development of the combination
without any exchange of product rights.

         Newly-Diagnosed Brain Tumor. In April 1999, we announced our plans to
discontinue study ALK01-040, which was a Phase III clinical trial of Cereport
and carboplatin for the treatment of newly-diagnosed brain tumor patients. The
study began enrollment in March 1998, and was designed to enroll patients with
high grade primary brain tumors following surgical resection of the tumor and
prior to the initiation of radiotherapy. The discontinuation of the study was
not based on any issues related to the safety or potential efficacy of Cereport
in this indication, but, based on our experience with the trial, we determined
that elements of the study design were inappropriate and that the probability of
successful completion was low. We are not planning to initiate another clinical
trial in this indication in the near future.

         Metastatic Brain Tumors. We are conducting a Phase I/II clinical trial
of Cereport and carboplatin in patients with metastatic brain tumors, or tumors
that have spread to the brain from other sites in the body. The study also
includes a dose escalation component, in which progressively larger doses of
Cereport are being investigated in this patient population. The study is
ongoing, and is expected to be completed in 1999. The results are expected to
provide information useful for determining whether to proceed with further
clinical trials in this indication.

         Pediatric Brain Tumors. The Pediatric Branch of the National Cancer
Institute is conducting two separate studies of Cereport and carboplatin in
pediatric patients with primary brain tumors. The first study began in August
1996 and enrolled 25 patients. The study is a non-controlled, open label Phase
I/II clinical trial of intravenous Cereport and carboplatin in pediatric brain
tumor patients who have failed other therapies. The second study began in June
1998, and is a Phase II multi-center study, in pediatric brain tumor patients.
Ten centers will enroll up to a total of 146 children over two to four years.

AIR

         Product Development Strategy. Our strategy is to generate multiple
product opportunities by applying the AIR technology to the development of
superior pulmonary formulations of small molecules and proteins and peptides. We
believe these formulations have the potential to expand the utilization of these
products and improve the competitive advantage of our collaborators in major
markets.

         The product development plan for individual AIR formulations is
expected to proceed in several stages. First, we, either on our own or pursuant
to a collaboration, conduct initial feasibility work to test various AIR
formulations for a particular drug in vitro and in vivo. Following the
successful completion of the feasibility stage, preclinical development and
manufacturing scale-up activities directed toward the initiation of clinical
trials of the AIR formulation would be conducted in collaboration with a
partner.

         We are currently collaborating with undisclosed partners on the
development of certain pharmaceutical product candidates. In addition, we are
developing two product candidates on our own that are in clinical trials.

         AlbuLast. AIR has formulated and is conducting a Phase I clinical trial
for AlbuLast, its proprietary formulation of albuterol sulfate which is designed
to provide both immediate and long-term relief from asthma symptoms. An
undisclosed pharmaceutical company has an option to develop AlbuLast with AIR in
exchange for certain development funding as well as milestones and royalties.


                                       10
<PAGE>   11
         EstroLast. We are developing an AIR formulation of the generic drug
estradiol for estrogen replacement therapy. Probative human studies are ongoing.
We retain rights to commercialize all estradiol formulations.

ORAL TECHNOLOGIES

         The RingCap and DST technologies, licensed from ALZA in April 1998, are
both in the early stages of development.

COLLABORATIVE ARRANGEMENTS

         Our business strategy includes forming collaborations to provide
technological, financial, marketing, manufacturing and other resources. We have
entered into several corporate collaborations.

         Genentech, Inc.

         In November 1996, we announced the completion of a Phase I clinical
trial of a ProLease rhGH formulation in adults. Based in part on the successful
completion of the Phase I trial, Genentech exercised its option to enter into a
license agreement and obtained from us a license coexclusive in the United
States and exclusive in the rest of the world for a ProLease formulation of
rhGH. In April 1999, Alkermes and Genentech amended and restated the license
agreement to conduct expanded development activities, including clinical trials
in an additional indication, process and formulation development and
manufacturing. We will be responsible for conducting additional clinical trials
and manufacturing for Nutropin Depot and are to receive manufacturing revenues
and royalties on sales.

         Genentech has the right to terminate the agreement for any reason upon
90 days' written notice or, if we have begun manufacturing the ProLease product
for commercial sale, upon six months' written notice. In addition, either party
may terminate the agreement upon the other party's material default which is not
cured within 90 days of written notice, or upon the other party's insolvency or
bankruptcy.

         In connection with the expanded collaboration in April 1999, Genentech
purchased 3,500 shares of our 1999 Redeemable Convertible Exchangeable Preferred
Stock for an aggregate purchase price of $35 million. We will use the proceeds
from the preferred stock to fund the expanded rhGH program for calendar years
1999 and 2000. See "Market for Our Common Stock and Related Stockholder
Matters."

         To fund our activities during the initial phase of the collaboration,
Genentech loaned us the aggregate amount of $3.5 million pursuant to a
Convertible Promissory Note dated January 31, 1995 (the "Note"). The outstanding
principal amount of the Note accrues interest at the prime rate of interest as
reported by the Bank of America NT & SA from time to time and is convertible
into common stock based on the average closing price of the common stock for the
20 trading days ending the day before the conversion date. The outstanding
principal amount of the Note and accrued but unpaid interest thereon becomes due
and payable on January 31, 2000.

         Johnson & Johnson - Erythropoietin

         In January 1998, we entered into a development and license agreement
and a supply and license agreement with Ortho Pharmaceutical, an affiliate of
Johnson & Johnson, for the development of a


                                       11
<PAGE>   12
ProLease formulation of erythropoietin ("ProLease EPO"). We are developing a
sustained release formulation of EPO for the treatment of various types of
anemia.

         Pursuant to the development agreement, Johnson & Johnson obtained an
exclusive, worldwide, royalty-bearing license to make, use and sell products
resulting from such agreement. In exchange, Johnson & Johnson is to provide us
with research and development funding, milestone payments and royalty payments
based on sales, if any, of ProLease EPO. Johnson & Johnson will be responsible
for conducting clinical trials, if any, and securing regulatory approvals and,
together with its affiliates, will be responsible for the marketing of any
products that result from the collaboration. We will manufacture any such
products for commercial sale and are to receive manufacturing revenues and
royalties on sales.

         Johnson & Johnson may terminate the development agreement for any
reason, upon 90 days' written notice if such termination notice occurs prior to
filing an NDA with the FDA, or upon six months' written notice if such notice
occurs subsequent to such a filing. In addition, either party may terminate the
development agreement and the related supply agreement upon a material default
or breach by the other party of such agreement which is not cured within 60
days' notice, or upon the other party's insolvency or bankruptcy.

         Janssen Pharmaceutica International

         Pursuant to a development agreement, we are collaborating with Janssen,
an affiliate of Johnson & Johnson, in the development of a sustained release
formulation of RISPERDAL utilizing the Medisorb technology. In October 1996, we
announced the expansion of the development agreement. Under the development
agreement, we are responsible for production of RISPERDAL for clinical trials.
Janssen is responsible for conducting clinical trials of RISPERDAL and securing
all necessary regulatory approvals. Janssen provides development funding to us,
assuming RISPERDAL continues in clinical development. We will manufacture any
such products for commercial sale and are to receive manufacturing revenues and
royalties on sales.

         Under related license agreements, Janssen and an affiliate have
exclusive worldwide licenses from us to manufacture, use and sell the Medisorb
formulation of RISPERDAL. If Janssen decides to employ third-party suppliers of
RISPERDAL, we have a right of first refusal for the manufacture and supply of
such product and component bio-absorbable polymers thereof. Under the license
agreements, Janssen is required to pay us certain royalties with respect to all
Medisorb formulations of RISPERDAL sold to customers. Janssen can terminate the
development agreement or the license agreement upon 30 days' prior written
notice.

         Alkermes Clinical Partners, L.P.

         In April 1992, units consisting of limited partnership interests in the
Partnership and warrants to purchase our Common Stock were sold to investors in
a private placement (the "Private Placement"). The proceeds of the $46 million
Private Placement have been used to fund the further development and clinical
testing of Cereport for human pharmaceutical use in the United States, Canada
and Europe. Such funding was not sufficient to complete clinical trials and seek
regulatory approval of Cereport. Since the completion of funding from the
Partnership, which ended during the quarter ended June 30, 1996, we have used,
and intend to continue to use, our own resources to develop Cereport, but may
seek alternative sources of funding, including additional collaborators.


                                       12
<PAGE>   13
         Pursuant to a product development agreement, dated March 6, 1992, we
transferred substantially all of our rights to the RMP technology, including
Cereport, to the Partnership. We have an option to purchase all of the limited
partnership interests in the Partnership (the "Purchase Option") and thereby
reacquire the transferred technology. We are required to fund the development of
Cereport to maintain the Purchase Option.

         The Partnership may terminate the research program for any or all
products upon the affirmative vote of 75% of the directors of the general
partner of the Partnership, Alkermes Development Corporation II ("ADC II"), one
of our wholly owned subsidiaries, that such research is not feasible or is
uneconomic. The Partnership may terminate the marketing program for any or all
products upon the affirmative vote of 75% of the directors of ADC II based on
the directors' good faith business judgment. The Partnership may also terminate
the research or marketing program if we have materially breached the agreement
and not cured such breach within 30 days' written notice. Both parties may
terminate the research or marketing program upon mutual consent to terminate or
upon the insolvency or bankruptcy of the other party.

         The Partnership has granted us an exclusive interim license to
manufacture and market Cereport for human pharmaceutical use in the United
States and Canada. Upon the first marketing approval of Cereport by the FDA, we
are obligated to make a payment to the Partnership equal to 20% of the aggregate
capital contributions of all limited partners. Additionally, we will pay a 12%
royalty on revenues from any sales of Cereport in the United States and Canada
and, in certain circumstances, a 10% royalty on revenues from any sales of
Cereport in Europe. The interim license will terminate if we do not exercise the
Purchase Option. We can exercise the Purchase Option by making a payment to the
Partnership equal to 80% of the aggregate capital contributions of all limited
partners in addition to royalty payments in the same percentages as provided for
under the interim license agreement.

         The general partner of the Partnership is ADC II. Fifty percent of the
members of the board of directors of ADC II are persons not affiliated with us.
Such non-affiliated persons were nominated by the sales agent for the Private
Placement. The sales agent will continue to have the right to nominate at least
half of the members of ADC II's board of directors until ADC II or some other
affiliate of Alkermes ceases to be the general partner of the Partnership, the
Partnership terminates in accordance with the terms of the Limited Partnership
Agreement or the sales agent's venture capital investment partnership ceases to
be a limited partner of the Partnership.

         ALZA Corporation

         In October 1997, we, along with ALZA, announced that we had entered
into an agreement relating to the development and commercialization of Cereport.
Under the terms of the agreement, ALZA made a $10.0 million upfront payment to
us to fund clinical development; in return, ALZA has the option to acquire
exclusive, worldwide, commercialization rights to Cereport, subject to the
rights and obligations of the Partnership. If ALZA chooses to exercise its
option, ALZA will make additional payments to cover costs associated with
advanced clinical development. If Cereport is commercialized successfully by
ALZA, ALZA will pay us certain milestone payments. We would be responsible for
the manufacturing of Cereport and we would share approximately equally in
profits from sales of the product.


                                       13
<PAGE>   14
MANUFACTURING

         The manufacture of our product candidates for clinical trials and
commercial purposes is subject to current GMP and other federal regulations. We
have never operated an FDA-approved manufacturing facility, and there can be no
assurance that we will obtain necessary approvals for commercial manufacturing.

         If we are not able to develop manufacturing capacity and experience or
to continue to contract for manufacturing capabilities on acceptable terms, our
ability to conduct preclinical testing and clinical trials will be compromised.
In addition, delays in obtaining regulatory approvals might result, as well as
delays of commercial sales if approvals are not obtained on a timely basis. Such
delays could materially adversely affect our competitive position and our
business, financial condition and results of operations.

         Each of our drug delivery systems utilizes a distinct manufacturing
process.

         ProLease

         ProLease manufacturing involves microencapsulation of drug substances
provided to us by our collaborators in small polymeric microspheres using
extremely cold processing conditions suitable for fragile molecules. The
ProLease manufacturing process consists of two basic steps. First, the drug is
formulated with stabilizing agents and dried to create a fine powder. Second,
the powder is microencapsulated at very low temperatures. Pursuant to agreements
with certain of our collaborators, we have the right to manufacture ProLease
products for commercial sale.

         In October 1998, we completed the construction of a new commercial
scale ProLease manufacturing facility of approximately 32,000 square feet. The
facility includes two manufacturing suites, one of which we plan to dedicate to
the production of Nutropin Depot for commercial scale. We have validated the
facility and completed manufacturing of validation lots as part of the Nutropin
Depot NDA submission, but the facility has not yet been inspected by the FDA.

         We also have an in-house clinical production facility that we have
validated for manufacturing in accordance with GMP. The facility is being used
to manufacture product candidates incorporating our ProLease sustained release
delivery system for use in clinical trials.

         Medisorb

         The Medisorb manufacturing process is significantly different from the
ProLease process and is based on a method of encapsulating small molecule drugs,
provided by our collaborator(s), in polymers using a large-scale emulsification.
The Medisorb manufacturing process consists of three basic steps. First, the
drug is combined with a polymer solution. Second, the drug/polymer solution is
mixed in water to form liquid microspheres (an emulsion). Third, the liquid
microspheres are dried to produce finished product.

         In June 1998, we completed construction of a 20,000 square foot
addition to and modification of our GMP manufacturing facility for commercial
scale Medisorb manufacturing in Wilmington, Ohio. We are manufacturing the
Medisorb formulation of RISPERDAL for use by Janssen in clinical trials at this
facility. The facility has not been inspected by the FDA.


                                       14
<PAGE>   15
         Cereport

         Cereport is a small peptide manufactured using standard synthetic
techniques. We rely on an independent European pharmaceutical company for the
manufacture and supply of Cereport. Scale-up of the Cereport manufacturing
process to support international clinical trials and commercial launch has been
completed. Other companies have been identified which could manufacture and
supply our requirements for Cereport.

         AIR

         The AIR manufacturing process uses spray drying. We take drugs provided
by our partners or purchased from generic manufacturers, combine the drugs with
certain excipients commonly used in other aerosol formulations and spray dry
the solution in commercial spray dryers. During the manufacturing process,
solutions of drugs and excipients are spray dried to form a free flowing powder
and the powder is filled and packaged into final dosage units. AIR has a
manufacturing facility which is part of the 18,000 square foot facility AIR
leases in Cambridge, Massachusetts, where powders and final dosage units are
prepared under GMP for use in clinical trials. Our current manufacturing
facility and equipment have the capacity to produce commercial scale quantities
of certain product candidates. AIR's inhalation device is produced under GMP at
a contract manufacturer in the United States.

         DST and RingCap

         We currently manufacture DST in our facility in Blue Ash, Ohio. The DST
manufacturing process uses customized machinery which we have installed and
which we currently operate at a scale capable of producing products for
development and market research studies.

          The RingCap system combines conventional matrix tablet technology and
capsule banding processes which permit large-scale production. We believe
RingCap can provide a cost-effective way to manufacture controlled release
tablets.

MARKETING

         In October 1997, we entered into an agreement with ALZA pursuant to
which ALZA made an upfront payment of $10.0 million to fund clinical development
in exchange for an exclusive option to enter into a worldwide exclusive
commercialization agreement for Cereport. If Cereport is successfully
commercialized by ALZA, ALZA will pay us certain milestone payments. Under the
terms of the agreement, we are responsible for the manufacture of Cereport, and
we will share approximately equally in profits from the sale of the product.

         We intend to market any ProLease, Medisorb, AIR, DST or RingCap
products through corporate partners. We have entered into development
agreements, which include sales and marketing arrangements, for ProLease product
candidates with Genentech and Johnson & Johnson, and for the Medisorb
formulation of RISPERDAL with Janssen. See "Collaborative Arrangements."

         We currently have no experience in marketing or selling pharmaceutical
products. In order to achieve commercial success for any product candidate
approved by the FDA, we must either develop a marketing and sales force or enter
into arrangements with third parties to market and sell our products. There can
be no assurance that we will successfully develop such experience or that we
will be able to


                                       15
<PAGE>   16
enter into marketing and sales agreements with others on acceptable terms, if at
all. If we develop our own marketing and sales capability, we will compete with
other companies that currently have experienced and well funded marketing and
sales operations. To the extent we enter into co-promotion or other sales and
marketing arrangements with other companies, any revenues received by us will be
dependent on the efforts of others, and there can be no assurance that such
efforts will be successful.

COMPETITION

         The biotechnology and pharmaceutical industries are subject to rapid
and substantial technological change. We face, and will continue to face,
intense competition in the development, manufacturing, marketing and
commercialization of our product candidates from academic institutions,
government agencies, research institutions, biotechnology and pharmaceutical
companies, including our collaborators, and drug delivery companies. There can
be no assurance that developments by others will not render our product
candidates or technologies obsolete or noncompetitive, or that our collaborators
will not choose to use competing drug delivery methods. At the present time, we
have no sales force or marketing or commercial manufacturing experience. In
addition, many of our competitors and potential competitors have substantially
greater capital resources, manufacturing and marketing experience, research and
development resources and production facilities than we do. Many of these
competitors also have significantly greater experience than we in undertaking
preclinical testing and clinical trials of new pharmaceutical products and
obtaining FDA and other regulatory approvals.

         With respect to Cereport, we believe that there are currently no
products approved by the FDA for increasing the permeability of the blood-brain
barrier. There are, however, many novel experimental therapies for the treatment
of brain tumors and central nervous system infections being tested in the United
States and Europe.

         With respect to ProLease and Medisorb, we are aware that there are
other companies developing sustained release delivery systems for pharmaceutical
products. With respect to AIR we are aware that there are other companies
marketing or developing pulmonary delivery systems for pharmaceutical products.
There are also numerous companies marketing or developing oral technologies
which will compete with DST and RingCap. In addition, other companies are
developing new chemical entities which, if developed successfully, could compete
against our formulations of the products of our collaborators. These chemical
entities are being designed to have different mechanisms of action or improved
safety and efficacy. In addition, our collaborators may develop, either alone or
with others, products that compete with the development and marketing of our
product candidates.

         There can be no assurance that we will be able to compete successfully
with such companies. The existence of products developed by our competitors, or
other products or treatments of which we are not aware, or products or
treatments that may be developed in the future, may adversely affect the
marketability of products developed by us.

PATENTS AND PROPRIETARY RIGHTS

         Our success will be dependent, in part, on our ability to obtain patent
protection for our product candidates and those of our collaborators,
maintaining trade secret protection and operating without infringing upon the
proprietary rights of others.


                                       16
<PAGE>   17
         We have a proprietary portfolio of patent rights and exclusive licenses
to patents and patent applications. We have filed numerous United States and
international patent applications directed to composition of matter as well as
processes of preparation and methods of use, including applications relating to
permeabilizers, certain rights to which have been licensed to the Partnership
and to each of our delivery technologies. We own a total of 42 issued patents.
In the future, we plan to file further United States and foreign patent
applications directed to new or improved products and processes. The United
States patents issued to us will expire between 2000 and 2016. We intend to file
additional patent applications when appropriate and intend to defend our patent
position aggressively.

         We have exclusive rights through licensing agreements with several
institutions to twelve issued United States patents, a number of United States
patent applications and corresponding foreign patents and patent applications in
many countries, subject in certain instances to the rights of the United States
government to use the technology covered by such patents and patent
applications. The United States patents that have been licensed to us will
expire between the years 2007 and 2016. Under certain licensing agreements, we
currently pay annual license fees and/or minimum annual royalties. During the
fiscal year ended March 31, 1999, such fees were $127,000. In addition, under
all licensing agreements, we are obligated to pay royalties on future sales of
products, if any, covered by the licensed patents.

         We know of several U.S. patents issued to other parties that relate to
our product candidates. One of those parties has asked us to compare our
Medisorb technology to that party's patented technology. The manufacture, use,
offer for sale, sale or importing of these product candidates might infringe on
the claims of these patents. A party might file an infringement action against
us. Our cost of defending such an action is likely to be high and we might not
receive a favorable ruling.

         We also know of patent applications filed by other parties in the
United States and various foreign countries that may relate to some of our
product candidates if issued in their present form. If patents are issued to any
of these applicants, we may not be able to manufacture, use, offer for sale, or
sell some of our product candidates without first getting a license from the
patent holder. The patent holder may not grant us a license on reasonable terms
or it may refuse to grant us a license at all. This could delay or prevent us
from developing, manufacturing or selling those of our product candidates that
would require the license.

         We try to protect our proprietary position by filing United States and
foreign patent applications related to our proprietary technology, inventions
and improvements that are important to the development of our business. Because
the patent position of biopharmaceutical companies involves complex legal and
factual questions, enforceability of patents cannot be predicted with certainty.
Patents, if issued, may be challenged, invalidated or circumvented. Thus, any
patents that we own or license from others may not provide any protection
against competitors. Our pending patent applications, those we may file in the
future, or those we may license from third parties, may not result in patents
being issued. And, if issued, they may not provide us with proprietary
protection or competitive advantages against competitors with similar
technology. Furthermore, others may independently develop similar technologies
or duplicate any technology that we have developed. The laws of certain foreign
countries do not protect our intellectual property rights to the same extent as
do the laws of the United States.


                                       17
<PAGE>   18
         We also rely on trade secrets, know-how and technology, which are not
protected by patents, to maintain our competitive position. We try to protect
this information by entering into confidentiality agreements with parties that
have access to it, such as our corporate partners, collaborators, employees and
consultants. Any of these parties may breach the agreement and disclose our
confidential information or our competitors might learn of the information in
some other way. If any trade secret, know-how or other technology not protected
by a patent were to be wrongly disclosed to a competitor, our business and
financial condition could be adversely affected.

GOVERNMENT REGULATION

         The manufacture and marketing of pharmaceutical products in the United
States require the approval of the FDA under the Federal Food, Drug and Cosmetic
Act. Similar approvals by comparable agencies are required in most foreign
countries. The FDA has established mandatory procedures and safety standards
which apply to the preclinical testing and clinical trials, manufacture and
marketing of pharmaceutical products. Pharmaceutical manufacturing facilities
are also regulated by state, local and other authorities.

         As an initial step in the FDA regulatory approval process, preclinical
studies are typically conducted in animal models to assess the drug's efficacy
and to identify potential safety problems. The results of these studies must be
submitted to the FDA as part of an Investigational New Drug application ("IND"),
which must be reviewed by the FDA before proposed clinical testing can begin.
Typically, clinical testing involves a three-phase process. Phase I trials are
conducted with a small number of subjects and are designed to provide
information about both product safety and the expected dose of the drug. Phase
II trials are designed to provide additional information on dosing and
preliminary evidence of product efficacy. Phase III trials are large scale
studies designed to provide statistical evidence of efficacy and safety in
humans. The results of the preclinical testing and clinical trials of a
pharmaceutical product are then submitted to the FDA in the form of a New Drug
Application ("NDA"), or for a biological product in the form of a Product
License Application ("PLA"), for approval to commence commercial sales.
Preparing such applications involves considerable data collection, verification,
analysis and expense. In responding to an NDA or PLA, the FDA may grant
marketing approval, request additional information or deny the application if it
determines that the application does not satisfy its regulatory approval
criteria.

         Prior to marketing, any product developed by us or our collaborators
must undergo an extensive regulatory approval process, which includes
preclinical testing and clinical trials of such product candidate to demonstrate
safety and efficacy. This regulatory process can require many years and the
expenditure of substantial resources. Data obtained from preclinical testing and
clinical trials are subject to varying interpretations, which can delay, limit
or prevent FDA approval. In addition, changes in FDA approval policies or
requirements may occur or new regulations may be promulgated which may result in
delay or failure to receive FDA approval. Similar delays or failures may be
encountered in foreign countries. Delays and costs in obtaining regulatory
approvals would have a material adverse effect on our business, financial
condition and results of operations.

         Among the conditions for NDA or PLA approval is the requirement that
the prospective manufacturer's quality control and manufacturing procedures
conform on an ongoing basis with GMP. Before approval of an NDA or PLA, the FDA
will perform a prelicensing inspection of the facility to determine its
compliance with GMP and other rules and regulations. In complying with GMP,
manufacturers must continue to expend time, money and effort in the area of
production and quality


                                       18
<PAGE>   19
control to ensure full technical compliance. After the establishment is
licensed, it is subject to periodic inspections by the FDA.

         The requirements which we must satisfy to obtain regulatory approval by
governmental agencies in other countries prior to commercialization of its
products in such countries can be as rigorous and costly as those described
above.

         We are also subject to various laws and regulations relating to safe
working conditions, laboratory and manufacturing practices, experimental use of
animals and use and disposal of hazardous or potentially hazardous substances,
including radioactive compounds and infectious disease agents, used in
connection with our research. Compliance with laws and regulations relating to
the protection of the environment has not had a material effect on capital
expenditures, earnings or our competitive position. However, the extent of
government regulation which might result from any legislative or administrative
action cannot be accurately predicted.

EMPLOYEES

         As of June 10, 1999, we had approximately 300 full-time employees. A
significant number of our management and professional employees have had prior
experience with pharmaceutical, biotechnology or medical product companies. We
believe that we have been highly successful in attracting skilled and
experienced scientific personnel; however, competition for such personnel is
intense. None of our employees are covered by a collective bargaining agreement.
We consider our relations with employees to be good.

                                  RISK FACTORS

         Any investment in our common stock offering is very risky. An investor
should carefully consider the following risk factors in addition to the
remainder of this annual report on form 10-K before purchasing any of our
securities.

OUR DELIVERY TECHNOLOGIES MAY NOT PRODUCE SAFE, EFFICACIOUS OR COMMERCIALLY
VIABLE PRODUCTS

         We do not yet have a product that we can sell commercially and we
cannot guarantee that we will have one in the future. All of our product
candidates, except Nutropin Depot, need significant additional research and
development. Nutropin Depot, like all of our product candidates, requires FDA
approval before it can be marketed. To be profitable, we must develop,
manufacture and market our products, either alone or by collaborating with
others. This could take several years and we may never be successful in bringing
our product candidates to the market. A new drug may appear promising at an
early stage of development or after clinical trials and never reach the market,
or it may reach the market and not sell, for a variety of reasons. The drug may:

         -        Be shown to be ineffective or to cause harmful side effects
                  during preclinical testing or clinical trials;

         -        Fail to receive regulatory approval on a timely basis or at
                  all;

         -        Be hard to manufacture on a large scale;

         -        Be uneconomical;

         -        Not be prescribed by doctors or accepted by patients; or

         -        Infringe on proprietary rights of another party.

         If our technology fails to generate product candidates that lead to the
successful development and commercialization of products, or if our partners
decide not to pursue one of our product candidates, our business and financial
condition will be materially adversely affected.

THE FDA MAY NOT APPROVE OUR PRODUCT CANDIDATES

         Approval from the FDA is required to manufacture and market
pharmaceutical products in the United States. Other countries have similar
requirements. The process that pharmaceutical products must undergo to get this
approval is extensive and includes preclinical testing and clinical trials to
demonstrate safety and efficacy and a review of the manufacturing process to
ensure compliance with good manufacturing practices. This process can last many
years and be very costly and still be unsuccessful. FDA approval can be delayed,
limited or not granted at all for many reasons, including:

         -        A product candidate may not be safe or effective;

         -        Data from preclinical testing and clinical trials can be
                  interpreted by FDA officials in different ways than we
                  interpret it;


                                       21
<PAGE>   22
         -        The FDA might not approve our manufacturing processes or
                  facilities;

         -        The FDA may change its approval policies or adopt new
                  regulations; and

         -        A product candidate may not be approved for all the
                  indications we requested.

The process of getting approvals in foreign countries is subject to delay and
failure for the same reasons. Any delay in, or failure to receive, approval will
have a material adverse effect on our business and financial condition.

         Our collaborator Genentech submitted a new drug application for
Nutropin Depot on June 28, 1999. This is the first new drug application
submitted on one of our products. We cannot guarantee that the FDA will accept
this application, that it will be approved in a timely manner, or that it will
be approved at all.

         Most of our product candidates are drug delivery systems combined with
a drug in a single formulation to treat a specific condition. In most cases, the
FDA has already approved the drug used in these product candidates for treating
the condition targeted by the product candidate. Cereport is a separate
formulation from the drug it is intended to be used with but must be tested with
that drug. We are conducting clinical trials on Cereport with carboplatin, which
is a chemotherapeutic agent, in patients with a certain type of brain tumor. If
the FDA approves Cereport based on these trials, it will be for its use in
conjunction with carboplatin for the treatment of that type of brain tumor.
Unlike the drugs used with many of our product candidates, the FDA has not
approved carboplatin for treating the type of tumor that we are targeting, and
this could result in the FDA requiring additional clinical trials. However, the
FDA has approved carboplatin for the treatment of other types of cancerous
tumors. Any delay in the approval process for any of our product candidates will
result in increased costs that could materially and adversely affect our
business and financial condition.

         Regulatory approval of a product candidate is limited to specific
therapeutic uses for which the product has demonstrated safety and efficacy in
clinical testing. Approval of a product candidate could also be contingent on
post-marketing studies. In addition, any marketed drug and its manufacturer
continue to be subject to strict regulation after approval. Any unforeseen
problems with an approved drug or any violation of regulations could result in
restrictions on the drug, including its withdrawal from the market.

CLINICAL TRIALS FOR OUR PRODUCT CANDIDATES ARE EXPENSIVE AND THEIR OUTCOME IS
UNCERTAIN

         Conducting clinical trials is a lengthy, time-consuming and expensive
process. Before obtaining regulatory approvals for the commercial sale of any
products, we or our partners must demonstrate through preclinical testing and
clinical trials that our product candidates are safe and effective for use in
humans. We have incurred and will continue to incur substantial expense for, and
devote a significant amount of time to, preclinical testing and clinical trials.

         Historically, the results from preclinical testing and early clinical
trials have often not predicted results of later clinical trials. A number of
new drugs have shown promising results in clinical trials, but subsequently
failed to establish sufficient safety and efficacy data to obtain necessary
regulatory approvals. Data obtained from preclinical and clinical activities are
susceptible to varying interpretations, which may delay, limit or prevent
regulatory approval. In addition, regulatory delays or


                                       22
<PAGE>   23
rejections may be encountered as a result of many factors, including changes in
regulatory policy during the period of product development.

         Clinical trials conducted by us, by our collaborators or by third
parties on our behalf may not demonstrate sufficient safety and efficacy to
obtain the requisite regulatory approvals for our product candidates. Regulatory
authorities may not permit us to undertake any additional clinical trials for
our product candidates.

         Clinical trials of each of our product candidates involve a drug
delivery technology and a drug, either as a single formulation or, as in the
case of Cereport, as two products administered in conjunction with each other.
This makes testing more complex because the outcome of the trials depends on the
performance of our technology in combination with a drug.

         We have other product candidates in preclinical development, and we
have not submitted investigational new drug applications or begun clinical
trials for these product candidates. Our preclinical and clinical development
efforts may not be successfully completed. We may not file further
investigational new drug applications. We or our collaborators may not begin
clinical trials as planned.

         Completion of clinical trials may take several years or more. The
length of time can vary substantially with the type, complexity, novelty and
intended use of the product candidate. Our commencement and rate of completion
of clinical trials may be delayed by many factors, including:

         -        Our inability to recruit patients at the expected rate;

         -        The failure of clinical trials to demonstrate a product
                  candidate's efficacy;

         -        Our inability to follow patients adequately after treatment;

         -        Our inability to predict unforeseen safety issues;

         -        Our inability to manufacture sufficient quantities of
                  materials used for clinical trials; and

         -        The potential for unforeseen governmental or regulatory
                  delays.

         If a product candidate fails to demonstrate safety and efficacy in
clinical trials, this failure may delay development of other product candidates
and hinder our ability to conduct related preclinical testing and clinical
trials. As a result of these failures, we may also be unable to find additional
collaborators or to obtain additional financing. Our business and financial
condition may be materially adversely affected by any delays in, or termination
of, our clinical trials.

WE ANTICIPATE WE WILL INCUR CONTINUED LOSSES FOR THE FORESEEABLE FUTURE

         We have had net operating losses since being founded in 1987. At March
31, 1999, our accumulated deficit was $180.9 million (after giving effect to our
acquisition of Advanced Inhalation Research on February 1, 1999 which was
accounted for as a pooling of interests). These losses principally consist of
the costs of research and development, the costs of acquiring rights to research
and development performed by others and general and administrative expenses. The
majority of revenues that we have received have come from collaboration and
development agreements, research grants and


                                       23
<PAGE>   24
interest income. We expect to incur substantial additional expenses over the
next several years as our research and development activities, including
clinical trials, accelerate and as we prepare to manufacture products for
commercial sale. Because we do not expect to generate significant revenues from
the sale of products, if any, for several years, we anticipate that additional
expenses will result in losses.

         Our future profitability depends, in part, on:

         -        Obtaining regulatory approval for our product candidates;

         -        Entering into agreements to develop and commercialize
                  products;

         -        Developing the capacity to manufacture and market products or
                  entering into agreements with others to do so;

         -        Market acceptance of our products;

         -        The ability to obtain additional research and development
                  funding from collaborative partners; and

         -        The ability to achieve certain product development milestones.

         We may not achieve any or all of these goals and, thus, cannot provide
assurances that we will ever achieve significant revenues or profits. Even if we
do receive regulatory approval of one or more of our products, we may not
achieve significant commercial success.

         Our recently completed manufacturing facilities in Cambridge and Ohio
require specialized personnel and are expensive to operate and maintain. Any
delay in the approval of product candidates to be manufactured in these
facilities will require us to continue to operate these expensive facilities and
retain the specialized personnel, which may increase our expected losses.

WE NEED TO SPEND SUBSTANTIAL FUNDS TO BECOME PROFITABLE

         We believe that our liquid assets, anticipated funding from our
collaborators and interest income will satisfy our capital and operating
requirements for the foreseeable future, but we cannot guarantee that this will
be the case. We will need to spend substantial amounts of money before we can be
profitable, if ever. The amount we will spend, and when we will spend it, will
depend, in part, on:

         -        How our research and development programs, including clinical
                  trials, progress;

         -        How much time and expense will be required to receive FDA
                  approval for our product candidates;

         -        The cost of building, operating and maintaining manufacturing
                  facilities;

         -        How many product candidates we pursue;

         -        How much time and money we need to prosecute and enforce
                  patent rights;


                                       24
<PAGE>   25
         -        How competing technological and market developments affect our
                  product candidates;

         -        The cost of possible acquisitions of drug delivery
                  technologies, products or companies;

         -        The cost of obtaining licenses to use technology owned by
                  others; and

         -        Whether and how we choose to exercise our option to purchase
                  the limited partnership interests in Alkermes Clinical
                  Partners.

         If we require additional funds to complete any of our programs, we may
seek funds through arrangements with collaborators, by issuing securities or
through debt financing. If we can only raise additional funds on terms that are
not favorable to us, we may have to cut back significantly on one or more of our
programs, give up some of our rights to our technologies or product candidates
or agree to reduced royalty rates from collaborators.

WE RELY HEAVILY ON COLLABORATORS

         Our arrangements with collaborators and licensors are critical to our
success in bringing our product candidates to the market. In some cases, we
depend on these parties to conduct preclinical testing and clinical trials and
to provide funding for our development programs. Some of our collaborators can
terminate their agreements with us for no reason and on limited notice. We
cannot guarantee that any of these relationships will continue. Failure to make
or maintain these arrangements or a delay in a collaborator's performance may
materially and adversely affect our business and financial condition.

         We cannot control our collaborators' performance or the resources they
devote to our programs. If a collaborator fails to perform, the research,
development or commercialization program on which it is working will be delayed.
If this happens, we may have to use funds, personnel, laboratories and other
resources that we have not budgeted, and may not have, to continue the program,
or we may have to stop the program entirely. The failure of a collaborator to
perform or a loss of a collaborator may materially adversely affect our business
and financial condition.

         Disputes may arise between us and a collaborator and may involve the
issue of which of us owns the technology that is developed during a
collaboration. Such a dispute could delay the program on which the collaborator
or we are working. It could also result in expensive arbitration or litigation,
which may not be resolved in our favor.

         A collaborator may choose to use its own or other technology to develop
a way to deliver its drug and withdraw its support of our product candidate.

         Our collaborators could merge with or be acquired by another company or
experience financial or other setbacks unrelated to our collaboration that
could, nevertheless, adversely affect us.

         None of our drug delivery systems can be commercialized as stand-alone
products but must be combined with a drug. To develop any new product candidate
using one of these drug delivery systems, we must obtain the drug from another
party. We cannot provide assurances that we will be able to negotiate any such
drugs on reasonable terms.


                                       25
<PAGE>   26
OUR MANUFACTURING EXPERIENCE IS LIMITED AND WE HAVE NEVER MANUFACTURED AN
APPROVED PRODUCT

         We currently manufacture each of our product candidates, except for
Cereport. The manufacture of drugs for clinical trials and for commercial sale
is subject to regulation by the FDA under good manufacturing practices (GMP)
regulations and by other regulators under other laws and regulations. We have
manufactured product candidates for use in clinical trials but otherwise have no
manufacturing experience. We cannot assure you that we can successfully
manufacture each of our product candidates in sufficient quantities for
commercial sale, or in a timely or economical manner.

         In October 1998, we completed construction of a new commercial
manufacturing plant for Nutropin Depot and future ProLease product candidates.
In June 1998, we completed an expansion of our existing Medisorb manufacturing
facility. Neither of these facilities nor any of our other manufacturing
facilities has been inspected or validated by the FDA, a process by which the
FDA approves a facility for the manufacture of products to be sold. We cannot
guarantee that the FDA will approve either of these facilities or find them to
be in compliance with good manufacturing practices.

         We rely on an unrelated party to manufacture Cereport for use in
clinical trials. We expect to rely on the same party to manufacture Cereport for
commercial sale if Cereport receives FDA approval. If we are unable to do so, or
the manufacturer fails to perform as required, we may be unable to secure an
alternative manufacturer on reasonable terms or in a timely manner.

         If more of our product candidates progress to late stage development,
we will incur significant expenses in the expansion or construction of
manufacturing facilities and increases in personnel in order to manufacture
product candidates. The development of commercial scale manufacturing processes
is complex and expensive. We can provide no assurances that we will be able to
develop this manufacturing capability in a timely way or at all.

         If we fail to develop manufacturing capacity and experience, fail to
continue to contract for manufacturing on acceptable terms, or fail to
manufacture our product candidates at a commercial scale our development
programs will be adversely affected. This may result in delays in receiving FDA
approval for one or more of our product candidates or delays in the commercial
production of a product that has already been approved. Any such delays could
materially and adversely affect our business and financial condition.

WE ARE SUBJECT TO EXTENSIVE GOVERNMENT REGULATIONS AND WE MAY NOT BE ABLE TO
OBTAIN REGULATORY APPROVALS

         Our product candidates are subject to extensive and rigorous domestic
government regulation. The FDA regulates, among other things, the development,
testing, manufacture, safety, efficacy, record-keeping, labeling, storage,
approval, advertising, promotion, sale and distribution of biopharmaceutical
products. If our products are marketed abroad, they will also be subject to
extensive regulation by foreign governments. Certain material changes to an
approved product, such as manufacturing changes or additional labeling claims,
are subject to further FDA review and approval. Any required approvals, once
obtained, may be withdrawn. Further, if we fail to comply with FDA and other
regulatory requirements at any stage during the regulatory process, we may be
subject to sanctions, including:


                                       26
<PAGE>   27
         -        Delays, warning letters and fines;

         -        Product recalls or seizures and injunctions on sales;

         -        Refusal of the FDA to review pending market approval
                  applications or supplements to approval applications;

         -        Total or partial suspension of production;

         -        Withdrawals of previously approved marketing applications; and

         -        Civil penalties and criminal prosecutions.

         We are also subject to federal, state and local government regulation
in the conduct of our business, including regulations on employee safety and our
handling and disposal of hazardous and radioactive materials. Any new regulation
or change to an existing regulation could require us to implement costly capital
or operating improvements for which we have not budgeted. We cannot assure you
that these regulations will remain the same or that we will maintain compliance
with these regulations.

         We and our contract manufacturer of Cereport also are required to
comply with the FDA current good manufacturing practice regulations. Good
manufacturing practice regulations include requirements relating to quality
control, quality assurance and maintenance of records and documentation.
Manufacturing facilities are subject to inspection by the FDA and must be
approved before we can use them in commercial manufacturing of our products. We
or our contract manufacturer may be unable to comply with the applicable good
manufacturing practice requirements and other FDA regulatory requirements. If
Alkermes or our contract manufacturer fail to comply, our business and financial
condition will be materially adversely affected.

WE HAVE ONLY LIMITED RIGHTS TO CEREPORT

         We transferred to Alkermes Clinical Partners substantially all of our
rights to certain technology that includes Cereport and then entered into an
agreement with Alkermes Clinical Partners under which we perform research and
development of Cereport. Alkermes Clinical Partners issued securities and used
the proceeds from the sale of those securities to fund our research and
development of Cereport. Funding provided by Alkermes Clinical Partners was
insufficient to complete clinical trials and apply for FDA approval. Since June
1996, we have used our own funds to develop Cereport. So long as we continue
this funding, we have an option to purchase the limited partnership interests in
Alkermes Clinical Partners for cash or our common stock. If this purchase option
terminates, we will have no rights to Cereport or the related technology in the
United States or Canada.

         If we exercise this purchase option, we must make a substantial cash
payment or issue a large number of shares of common stock. The exercise of the
option may require us to record significant charges to earnings for the
purchase of in-process research and development. If we acquire rights to the
Cereport technology under the option, we will still be obliged to pay royalties
to the limited partners.

COMPETITION IN THE BIOTECHNOLOGY INDUSTRY

         We can provide no assurance that we will be able to compete
successfully against the competitive forces discussed below in developing,
marketing or selling our products.

         WE FACE INTENSE COMPETITION

         We face intense competition from academic institutions, government
agencies, research institutions and biotechnology and pharmaceutical companies,
including other drug delivery companies. Some of these competitors are also our
collaborators. These competitors are working to develop and market other drug
delivery systems, vaccines and other methods of preventing or reducing disease,
and new small-molecule and other classes of drugs that can be used without a
drug delivery system.

         We know of no products approved by the FDA or foreign regulatory
authorities for increasing the permeability of the blood-brain barrier, which is
the intended use of Cereport. However, there are other companies developing
sustained release drug delivery systems, pulmonary delivery systems and oral
delivery systems. In addition, we know of new chemical entities that are being
developed that, if successful, could compete against our product candidates.
These chemical entities are being designed to work differently than our product
candidates and may turn out to be safer or to work better than our product
candidates. Among the many experimental therapies being tested in the United
States and Europe, there may be some that we do not now know of that may compete
with our drug delivery systems or product candidates. Our collaborators could
choose a competing drug delivery system to use with their drugs instead of one
of our drug delivery systems.

         Many of our competitors have much greater capital resources,
manufacturing and marketing experience, research and development resources and
production facilities than we do. Many of them also have much more experience
than we do in preclinical testing and clinical trials of new drugs and in
obtaining FDA and foreign approvals. In addition, they may succeed in obtaining
patents that would make it difficult or impossible for us to compete with their
products.

         RAPID TECHNOLOGICAL CHANGE COULD RENDER OUR DRUG DELIVERY SYSTEMS
         OBSOLETE OR NONCOMPETITIVE

         Major technological changes can happen quickly in the biotechnological
and pharmaceutical industries; and the development by competitors of
technologically improved or different products may make our product candidates
obsolete or noncompetitive.

         THE COMPETITIVE NATURE OF OUR INDUSTRY COULD ADVERSELY AFFECT MARKET
         ACCEPTANCE OF OUR PRODUCTS

         Our product candidates may not gain market acceptance among physicians,
patients, healthcare payors and the medical community. The degree of market
acceptance of any product candidates that we develop will depend on a number of
factors, including:

         -        Demonstration of their clinical efficacy and safety;

         -        Their cost-effectiveness;


                                       28
<PAGE>   29
         -        Their potential advantage over alternative treatment methods;

         -        The marketing and distribution support they receive; and

         -        Reimbursement policies of government and third-party payors.

         Our product candidates, if successfully developed, will compete with a
number of drugs and therapies currently manufactured and marketed by major
pharmaceutical and other biotechnology companies. Our products may also compete
with new products currently under development by others or with products which
may cost less than our products. Physicians, patients, third-party payors and
the medical community may not accept or utilize our products. If our products do
not achieve significant market acceptance, our business and financial condition
will be materially adversely affected.

PATENT PROTECTION FOR OUR PRODUCTS IS IMPORTANT AND UNCERTAIN

         The following factors are important to our success:

         -        Receiving patent protection for our product candidates and
                  those of our collaborators;

         -        Maintaining our trade secrets;

         -        Not infringing on the proprietary rights of others; and

         -        Preventing others from infringing our proprietary rights.

         We will be able to protect our proprietary rights from unauthorized use
by third parties only to the extent that our proprietary rights are covered by
valid and enforceable patents or are effectively maintained as trade secrets.

         We know of several U.S. patents issued to other parties that relate to
our product candidates. One of those parties has asked us to compare our
Medisorb technology to that party's patented technology. The manufacture, use,
offer for sale, sale or importing of these product candidates might infringe on
the claims of these patents. A party might file an infringement action against
us. Our cost of defending such an action is likely to be high and we might not
receive a favorable ruling.

         We also know of patent applications filed by other parties in the
United States and various foreign countries that may relate to some of our
product candidates if issued in their present form. If patents are issued to any
of these applicants, we may not be able to manufacture, use, offer for sale, or
sell some of our product candidates without first getting a license from the
patent holder. The patent holder may not grant us a license on reasonable terms
or it may refuse to grant us a license at all. This could delay or prevent us
from developing, manufacturing or selling those of our product candidates that
would require the license.

         We try to protect our proprietary position by filing United States and
foreign patent applications related to our proprietary technology, inventions
and improvements that are important to the development of our business. Because
the patent position of biopharmaceutical companies involves complex legal and
factual questions, enforceability of patents cannot be predicted with certainty.
Patents, if issued, may be challenged, invalidated or circumvented. Thus, any
patents that we own or


                                       29
<PAGE>   30
license from others may not provide any protection against competitors. Our
pending patent applications, those we may file in the future, or those we may
license from third parties, may not result in patents being issued. And, if
issued, they may not provide us with proprietary protection or competitive
advantages against competitors with similar technology. Furthermore, others may
independently develop similar technologies or duplicate any technology that we
have developed. The laws of certain foreign countries do not protect our
intellectual property rights to the same extent as do the laws of the United
States.

         We also rely on trade secrets, know-how and technology, which are not
protected by patents, to maintain our competitive position. We try to protect
this information by entering into confidentiality agreements with parties that
have access to it, such as our corporate partners, collaborators, employees and
consultants. Any of these parties may breach the agreement and disclose our
confidential information or our competitors might learn of the information in
some other way. If any trade secret, know-how or other technology not protected
by a patent were to be wrongly disclosed to a competitor, our business and
financial condition could be adversely affected.

EFFORTS TO KEEP DOWN THE COST OF HEALTHCARE MAY THREATEN OUR PROFITABILITY

         Third-party payors, which include governments and private health
insurers, are increasingly challenging the prices charged for medical products
and services. In their attempts to reduce healthcare costs, they have also been
limiting their coverage and reimbursement levels for new drugs. In some cases,
they are refusing to cover the costs of drugs that are not new but are being
used for newly approved purposes. Patients who use a product that we may develop
might not be reimbursed for its cost. If third-party payors do not provide
adequate coverage and reimbursement for our products, if and when they reach the
market, doctors may not prescribe them or patients may not use them.

         The federal government and various state governments have considered
proposals to regulate the prices of prescription drugs, as is done in certain
foreign countries. We expect that there will be more proposals like these. If
any of these proposals are enacted, we may receive a lower price for our
products, if and when they reach the market, than we currently estimate. Lack of
adequate reimbursement or the enactment of price controls would have a material
adverse effect on our business and financial condition.

WE HAVE NO MARKETING OR SALES EXPERIENCE

         We currently have no experience in marketing or selling pharmaceutical
products. To achieve commercial success for any product that may be approved by
the FDA, we must either develop a marketing and sales force or contract with
another party to perform these services for us. In either case, we will be
competing with companies that have experienced and well-funded marketing and
sales operations. We may not be successful in developing a marketing and sales
force or in contracting with a third party on acceptable terms in selling our
products at all.

WE ARE EXPOSED TO PRODUCT LIABILITY CLAIMS

         We may be exposed to liability claims arising from the use of our
product candidates in clinical trials and the commercial sale of any products.
These claims may be brought by consumers, our collaborators or parties selling
the products. We currently carry liability insurance for claims arising from the
use of our product candidates during clinical trials in the amount of up to $10
million per occurrence


                                       30
<PAGE>   31
and $10 million in the aggregate. However, we cannot provide any assurance that
this coverage will be sufficient to satisfy any liabilities that may arise. As
our development activities progress, this coverage will be inadequate; and we
may be unable to get adequate coverage at an acceptable cost or we may be unable
to get adequate coverage at all. This could prevent or limit our
commercialization of our product candidates. Even if we are able to continue to
carry insurance that we believe is adequate, our financial condition may be
materially and adversely affected by a product liability claim.

WE MUST MEET CERTAIN FINANCIAL TESTS OR WE WILL DEFAULT UNDER OUR LOAN
AGREEMENTS

         We must maintain minimum levels of working capital, net worth and
liquid assets under the terms of our loan agreements.

WE MAY NOT BE ABLE TO RETAIN OUR KEY EXECUTIVES AND RESEARCH AND DEVELOPMENT
PERSONNEL

         Our success depends on the services of key employees in executive and
research and development positions. The loss of the services of one or more of
these employees could have a material adverse effect on us.

WE DO NOT ANTICIPATE PAYING DIVIDENDS ON OUR COMMON STOCK

         We have not paid cash dividends on our common stock and do not expect
to do so in the foreseeable future. We currently have outstanding 2,303,500
shares of preferred stock in two separate series. We must pay cash dividends to
the holders of the preferred stock, and any dividends that we do not pay will
accrue and remain owing to the holders of the preferred stock but will not bear
interest. We must pay the accumulated, unpaid dividends on 2,300,000 shares of
the preferred stock before we can declare or pay cash dividends on the common
stock.

WE MAY ISSUE MORE COMMON STOCK

         As discussed above under "We Need to Spend Substantial Funds to Become
Profitable," we may issue additional equity securities to raise funds, thus
reducing the ownership share of the company of current holders of our common
stock which may adversely affect the market price of the common stock. In
addition, for consideration that we have already received, we must issue common
stock to certain security holders and other parties under the circumstances
described below. Any of these parties could sell all or a large number of its
shares, which could adversely affect the market price of our common stock. Even
if none of these sales happen, the perception by investors that sales might
occur could adversely affect the market price of our common stock.

         CONVERTIBLE PREFERRED STOCK

         We may exchange our $3.25 convertible exchangeable preferred stock in
whole for debentures, but have no current plans to do so. Any holder of this
series of preferred stock, or the debentures for which it may have been
exchanged, may convert its shares or debentures into shares of common stock. We
have already registered for resale shares of our common stock for this purpose.
Each share of this series of preferred stock is currently convertible into
1.6878 shares of common stock for a total of 3,881,940 shares of common stock.


                                       31
<PAGE>   32
         Any holder of our 1999 redeemable convertible exchangeable preferred
stock may convert its shares into common stock (and non-voting common stock
which is convertible into common stock) at any time after September 1, 1999 that
our common stock is trading above $45 per share for at least ten consecutive
trading days. In addition, we may redeem all or a portion of the shares of this
series of preferred stock for cash or common stock (and non-voting common stock
which is convertible into common stock). We are obligated to register for resale
all shares of common stock after conversion or redemption for common stock. Each
share of this series of preferred stock is convertible into shares of common
stock based on an average of the closing price of common stock over a ten-day
period.

         CONVERTIBLE NOTE HELD BY GENENTECH

         In January 1995, we issued a Convertible Promissory Note in the
principal amount of $3.5 million to Genentech, Inc. We have the option to pay in
cash or convert the amount due on this note to our common stock. Under certain
circumstances, Genentech can require us to convert the amount due to common
stock and to register that stock. This note is due in January 2000.

         CONVERTIBLE NOTE HELD BY SCHERING

         In October 1998, we issued a promissory note in the principal amount of
$6 million to Schering Corporation. We have the option to pay in cash or convert
the amount due on this note to our common stock. If we convert the amount due
into common stock, we must register the common stock. This note is due in
October 2001.

         STOCK OPTIONS AND AWARDS; WARRANTS

         At June 10, 1999, we were obligated to issue the following shares of
common stock under the circumstances described:

         -        3,231,804 shares upon the exercise of stock options and
                  vesting of awards; and

         -        832,738 shares upon the exercise of warrants.

We have already registered these shares.

         COMMON STOCK OWNED BY ALZA CORPORATION

         We issued and registered for resale 2 million shares of common stock to
ALZA Corporation, of which they held 1,750,000 shares as of June 8, 1999. ALZA
also has the right to include these shares in any underwritten public offering
of our common stock. ALZA may sell all or any portion of these shares at any
time.

OUR COMMON STOCK PRICE IS HIGHLY VOLATILE

         The realization of any of the risks described in these "Risk Factors"
or other unforeseen risks could have a dramatic and adverse effect on the market
price of our common stock. Additionally, market prices for securities of
biotechnology and pharmaceutical companies, including ours, have historically
been very volatile. The market for these securities has from time to time
experienced significant price and volume fluctuations for reasons that were
unrelated to the operating performance of


                                       32
<PAGE>   33
any one company. In particular and in addition to circumstances described
elsewhere under "Risk Factors," the following factors can adversely affect the
market price of our common stock:

         -        Announcements of technological innovations or new therapeutic
                  products by us or others;

         -        Public concern as to the safety of drugs developed by us or
                  others;

         -        General market conditions;

         -        Changes in government regulations or patent decisions; and

         -        Developments of our corporate partners.

ANTI-TAKEOVER PROVISIONS MAY NOT BENEFIT SHAREHOLDERS

         We are a Pennsylvania corporation. Anti-takeover provisions of
Pennsylvania law could make it more difficult for a person or group to acquire
control of us, even if the change in control would be beneficial to
shareholders. Our articles of incorporation and bylaws also contain certain
provisions that could have a similar effect. The articles provide that our board
of directors may issue, without shareholder approval, preferred stock having
such voting rights, preferences and special rights as the board of directors may
determine. The issuance of preferred stock could make it more difficult for a
third party to acquire us.

OUR SYSTEMS MAY NOT BE YEAR 2000 COMPLIANT

         The Year 2000 problem concerns the application of computer systems
written using six (e.g., 12/31/99) versus eight (e.g., 12/31/1999) digits to
define the applicable date. This could result, among other things, in computer
systems recognizing "00" as the year 1900 rather than the year 2000. Computer
hardware, software and embedded chip equipment are potentially affected, and, if
such systems and components are not remediated satisfactorily, could lead to
operational interruptions and business misinformation. We are addressing the
Year 2000 problem in these systems and continue our analysis of the Year 2000
readiness of key third parties. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations - Year 2000."

         Our computer systems are complex, highly interdependent and there are a
number of risks associated with the complexity and high degree of integration of
the systems. For example, an incorrect classification of the importance of a
system or systems, or the cumulative effect of a number of low priority systems
that have not been remediated, could result in an unpredicted failure or
shutdown in one or more of our business, processing or manufacturing systems,
which could have a material adverse effect on production or cost of operations.
Our current belief is that this has a relatively low probability of occurring.
To minimize these risks, we are utilizing our skilled and knowledgeable internal
resources and have employed contract personnel in our decision-making processes
and to perform integrated systems testing.

         If the Year 2000 problem causes suppliers and utility providers to fail
to deliver essential materials and services, multiple disruptions of our
operations, computer infrastructure or telecommunications systems could result.
Because of the inherent uncertainties associated with the Year 2000 problem,
including understanding the Year 2000 readiness of these key third parties, it
is not


                                       33
<PAGE>   34
possible to quantify the potential impact at this time. However, failure of key
suppliers, utility providers or us to address properly and timely the Year 2000
problem could have a material adverse effect on our financial condition, results
of operations or liquidity. Furthermore, there can be no guarantee that any
contingency plans developed by us will prevent such failures from having a
material adverse effect. We believe that there is a low probability that these
multiple failures are likely to occur.

ITEM 2.  PROPERTIES

         We lease and occupy approximately 120,000 square feet of laboratory,
manufacturing and office space in Cambridge, Massachusetts under nine leases
expiring in the years 2001 to 2008. Several of the leases contain provisions
permitting us to extend the term of such leases for up to ten years. We have a
GMP clinical suite at our Massachusetts facility, which is for the manufacture
of product candidates incorporating the ProLease delivery system. We completed
construction of a new 32,000 square foot commercial scale ProLease manufacturing
facility in Cambridge, Massachusetts in October 1998. We operate a GMP
manufacturing facility for our AIR technology at one of our Cambridge,
Massachusetts facilities. We believe that our Massachusetts facilities are
adequate for our preclinical, clinical and commercial operations.

         We do not manufacture and do not expect to manufacture Cereport for
clinical trials. We have engaged a third party to manufacture preclinical,
clinical and commercial supplies of Cereport.

         Alkermes Europe, Ltd., one of our wholly owned subsidiaries, leases and
occupies approximately 4,600 square feet of office space in Cambridge, England
under a lease expiring in the year 2002.

         We own and occupy approximately 35,000 square feet of manufacturing,
office and laboratory space in Wilmington, Ohio. The facility contains a
state-of-the-art GMP sterile production facility specifically designed for the
production of Medisorb microspheres. Construction of a 20,000 square foot
addition and renovation of this facility to support commercial scale manufacture
of Medisorb product candidates was completed in June of 1998. We believe that
our Wilmington facility is adequate for its preclinical, clinical and commercial
operations.

         We also lease and occupy approximately 30,000 square feet of laboratory
and office space in Blue Ash, Ohio under a lease expiring in 2001. We operate
clinical scale manufacturing for our DST and RingCap technologies at this
facility. We believe that the Blue Ash facility is adequate for our operations.

         The number of shareholders of record on June 10, 1999 was 512. No
dividends have been paid on the common stock to date and we do not expect to
pay cash dividends thereon in the foreseeable future.

1999 Preferred Stock

         On April 14, 1999, we issued and sold 3,500 shares of 1999 Redeemable
Convertible Exchangeable Preferred Stock, par value $.01 per share (the "1999
Preferred Stock"), to Genentech, Inc. for an aggregate purchase price of
$35,000,000.

         The 1999 Preferred Stock was issued and sold in a transaction exempt
from the registration requirements of the Securities Act of 1933, as amended
(the "Securities Act") pursuant to Rule 506 of Regulation D promulgated under
the Securities Act. We reasonably believed that Genentech, Inc. was and is an
accredited investor, based on representations made to us by Genentech and by our
review of Genentech's filings with the SEC under the Securities Exchange Act of
1934, as amended.

         Dividends on the 1999 Preferred Stock are cumulative from the date of
original issue and are payable quarterly each March 1, June 1, September 1 and
December 1, at the rate of the three-month London Interbank Offer Rate (LIBOR)
and commenced June 1, 1999. The 1999 Preferred Stock has a liquidation
preference of $10,000 per share, plus accrued and unpaid dividends.

         The 1999 Preferred Stock is redeemable at our option, in whole or in
part, at any time at the redemption price of $10,000 per share plus accrued and
unpaid dividends, if any (the "1999 Redemption Price"). There will be a
mandatory redemption of any outstanding shares of the 1999 Preferred Stock on
January 1, 2009 at the 1999 Redemption Price. The 1999 Redemption Price may be
paid in cash or shares of our common stock or non-voting common stock at our
option.

         The holders of 1999 Preferred Stock are entitled to convert their
shares of 1999 Preferred Stock into shares of common stock and non-voting common
stock during any period after September 1, 1999 that the closing price of the
common stock on The Nasdaq National Market is listed above $45 per share for at
least 10 consecutive trading days. We have the option to redeem the 1999
Preferred Stock for cash


                                       36
<PAGE>   37
prior to conversion. Each share of 1999 Preferred Stock would be converted into
that number of shares of common stock and non-voting common stock obtained by
dividing $10,000 plus accrued and unpaid dividends by the average closing price
of the common stock for the 10 consecutive trading days prior to notice of
conversion. Non-voting common stock is convertible into shares of common stock
at the option of the holder and automatically upon the sale by the holder to a
non-affiliate.

         In no event are we required to issue, for redemption for stock or on
conversion, greater than 4,976,220 shares of common stock and non-voting common
stock, unless we obtain the prior approval of our shareholders.

         We are obligated to register for resale any shares of common stock
issued upon conversion or redemption upon such issuance.

AIR Transaction

         As of February 1, 1999, we issued 3,680,508 shares of our common stock
(the "AIR Shares") to the stockholders of Advanced Inhalation Research, Inc.
("AIR") in connection with the merger of one of our wholly owned subsidiaries
with and into AIR. Each share of the common stock of AIR was converted into
1.1829754 shares of our common stock on the effective date of the merger. As of
March 31, 1999, approximately 1,341,000 of the AIR Shares are restricted under
various restricted stock purchase agreements and cannot be resold until such
shares vest over a four year period at different amounts for each shareholder.

         The AIR Shares were issued in a transaction exempt from the
registration requirements of the Securities Act pursuant to Rule 506 of
Regulation D promulgated under the Securities Act to persons reasonably believed
to be accredited investors or investors who, alone or with their purchaser
representatives had such knowledge and experience in financial and business
matters that he or she was capable of evaluating the merits and risks of the
investment. The AIR Shares were issued to 34 purchasers.

         On April 2, 1999, we filed a registration statement on Form S-3 to
register for resale the AIR Shares, which was declared effective on May 13,
1999.

         Also in February 1999 and in connection with the merger, we assumed
stock options previously granted to certain persons by AIR. On April 2, 1999, we
filed a registration statement on Form S-3 to register 119,454 shares of our
common stock issuable upon exercise of such stock options, which was declared
effective on May 13, 1999.

$3.25 Preferred Stock

         In March 1998, we issued and sold 2,300,000 shares of $3.25 Convertible
Exchangeable Preferred Stock, par value $.01 per share (the "$3.25 Preferred
Stock"), to certain initial purchasers (the "Initial Purchasers"). The aggregate
purchase price was $115,000,000, of which $4,025,000 constituted the
underwriting discounts and commissions. The Initial Purchasers were BancAmerica
Robertson Stephens, NationsBanc Montgomery Securities LLC, Cowen & Company,
Credit Suisse First Boston Corporation, Merrill Lynch, Pierce, Fenner & Smith
Incorporated, J. P. Morgan Securities Inc., PaineWebber Incorporated and Smith
Barney Inc.


                                       37
<PAGE>   38
         The $3.25 Preferred Stock was issued and sold in transactions exempt
from the registration requirements of the Securities Act to persons reasonably
believed by the managers who placed the $3.25 Preferred Stock, the Initial
Purchasers, to be "qualified institutional buyers" (as defined in Rule 144A
under the Securities Act) (each a "QIB") or institutional accredited investors
or sophisticated investors.

         Dividends on the 2,300,000 shares of the $3.25 Preferred Stock are
cumulative from the date of original issue and are payable quarterly each
March 1, June 1, September 1 and December 1, at the annual rate of $3.25 per
share of $3.25 Preferred Stock and commenced June 1, 1998. Prior to March 6,
2001, the $3.25 Preferred Stock is not redeemable at our option. Thereafter the
$3.25 Preferred Stock is redeemable at our option, in whole or in part, at
declining redemption prices, together with accrued dividends. The $3.25
Preferred Stock has a liquidation preference of $50 per share, plus accrued and
unpaid dividends.

         The $3.25 Preferred Stock is exchangeable, in whole but not in part, at
our option on any dividend payment date beginning March 1, 1999 (the "Exchange
Date") for its 6-1/2% Convertible Subordinated Debentures (the "Debentures") at
the rate of $50 principal amount of Debentures for each share of $3.25 Preferred
Stock. The Debentures, if issued, will mature on the tenth anniversary of the
Exchange Date. The Debentures, if issued, will contain conversion and optional
redemption provisions substantially identical to those of the $3.25 Preferred
Stock.

         Holders of the $3.25 Preferred Stock are entitled at any time, subject
to prior redemption or repurchase, to convert any of the $3.25 Preferred Stock
or portions thereof into common stock, at an initial conversion rate of 1.6878
shares of common stock for each share of $3.25 Preferred Stock, subject to
certain adjustments.

         On April 15, 1998, we filed a registration statement on Form S-3 to
register the 2,300,000 shares of the $3.25 Preferred Stock, the $115,000,000
Debentures and 3,881,940 shares of common stock, issuable upon conversion of the
$3.25 Preferred Stock or upon conversion of the Debentures, if the Preferred
Stock is exchanged for Debentures. The effective date of such registration
statement was April 29, 1998.

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

ALKERMES, INC. AND SUBSIDIARIES

INTRODUCTION

         Alkermes is developing innovative pharmaceutical products based on
sophisticated drug delivery systems. The Company has several areas of focus: (i)
controlled, sustained release of injectable drugs lasting several days to
several weeks, utilizing its ProLease(R) and Medisorb(R) technologies; (ii) the
delivery of drugs into the brain past the blood-brain barrier, utilizing the
Cereport(TM) technology; (iii) oral delivery of drugs using its RingCap(TM) and
dose sipping technologies ("DST"); and (iv) the development of pharmaceutical
products based on proprietary pulmonary drug delivery technologies utilizing its
Advanced Inhalation Research, Inc. ("AIR") technology. Since its inception in
1987, the Company has devoted substantially all of its resources to its research
and development programs. Alkermes has not received any revenue from the sale of
products. The Company has been unprofitable since inception and expects to incur
substantial additional operating losses over the next few years. At March 31,
1999, the Company had an accumulated deficit of $180.9 million.

         The consolidated financial statements give retroactive effect to the
acquisition of AIR on February 1, 1999 (see Note 3 to the Consolidated Financial
Statements), which has been accounted for as a pooling of interests.

         The Company has funded its operations primarily through public
offerings and private placements of equity securities, bank loans and payments
under research and development agreements with collaborators, including Alkermes
Clinical Partners, L.P. ("Clinical Partners"), a research and development
limited partnership whose operations commenced in April 1992. The Company
generally develops its product candidates in collaboration with others on whom
the Company will rely for funding, development, manufacturing and/or marketing.

FORWARD-LOOKING STATEMENTS

         Any statements set forth below or otherwise made in writing or orally
by the Company with regard to its expectations as to financial results and other
aspects of its business may constitute forward-looking statements within the
meaning of the Private Securities Litigation Reform Act of 1995. Although the
Company believes that its expectations are based on reasonable assumptions
within the bounds of its knowledge of its business and operations, the Company's
business is subject to significant risks and there can be no assurance that
actual results of the Company's development activities and its results of
operations will not differ materially from its expectations. Factors which could
cause actual results to differ from expectations include, among others: (i) the
Company and its collaborators could not be permitted by regulatory authorities
to undertake clinical trials for RingCap or DST or to undertake additional
clinical trials for ProLease, Cereport, Medisorb or AIR product candidates or
clinical trials could be delayed; (ii) product candidates could be


                                       40
<PAGE>   41
ineffective or unsafe during clinical trials; (iii) the Company's collaborators
could elect to terminate or delay development programs; (iv) even if product
candidates appear promising at an early stage of development, product candidates
could fail to receive necessary regulatory approvals, be difficult to
manufacture on a large scale, be uneconomical, fail to achieve market
acceptance, be precluded from commercialization by proprietary rights of third
parties or experience substantial competition in the marketplace; (v) the
Company could incur difficulties or set-backs in obtaining the substantial
additional funding required to continue research and development programs and
clinical trials; (vi) even if clinical trials are completed and the data is
submitted to the Food and Drug Administration ("FDA") as a New Drug Application
("NDA") for marketing approval and to other health authorities as a marketing
authorization application, the NDA or marketing authorization application could
fail to be accepted, or upon acceptance, could fail to receive approval on a
timely basis, if at all; (vii) technological change in the biotechnology or
pharmaceutical industries could render the Company's product candidates obsolete
or noncompetitive; (viii) disputes with collaborators, termination of
collaborations or failure to negotiate acceptable new collaborative arrangements
for ProLease, Medisorb, AIR, RingCap or DST technologies, which are not
generally developed independently, or for Cereport, could occur; (ix) disputes
with Clinical Partners over rights to Cereport and related technology could
occur; and (x) difficulties or set-backs in obtaining and enforcing Alkermes'
patents and difficulties with the patent rights of others could occur.

RESULTS OF OPERATIONS

         The Company's research and development revenue under collaborative
arrangements was $33,892,107, $25,585,058 and $15,968,317 for the fiscal years
ended in 1999, 1998 and 1997, respectively. The increase in such revenue for
fiscal 1999 as compared to fiscal 1998 was mainly a result of the increased
funding and milestones earned under collaborative agreements related to the
Company's ProLease technology. The increase in such revenue for fiscal 1998 as
compared to fiscal 1997 was mainly the result of the increased funding and
milestones achieved under new or expanded collaborative agreements related to
the Company's ProLease, Medisorb and Cereport technologies. The Company's
research and development revenue under collaborative arrangement with related
party ended during fiscal 1997. This revenue was received from Clinical Partners
under a product development agreement entered into in March 1992.

         Interest and other income was $9,823,479, $5,781,511 and $2,443,317 for
the fiscal years ended in 1999, 1998 and 1997, respectively. The increase in
such revenue for fiscal 1999 as compared to fiscal 1998 was primarily a result
of the interest income earned on the net proceeds of $110.5 million from the
sale of 2,300,000 shares of the Company's $3.25 convertible exchangeable
preferred stock (the "Preferred Stock") in March 1998. The increase in such
revenue for fiscal 1998 as compared to fiscal 1997 was primarily a result of the
interest income earned on $49.7 million of net proceeds from the sale of
2,000,000 shares of the Company's common stock to ALZA Corporation ("ALZA") in
March 1997.



                                       41
<PAGE>   42
         The Company's total operating expenses were $84,771,956 for the fiscal
year ended in 1999 as compared to $43,948,770 and $38,624,765 for the fiscal
years ended in 1998 and 1997, respectively. As part of total operating expenses
in fiscal 1999, the Company recorded a $3.2 million nonrecurring charge in
fiscal 1999 for RingCap and DST technologies licensed from ALZA which are not
yet commercially viable. The total operating expenses for the Company also
included noncash compensation expenses of $16,239,311, $2,183,373 and $173,094
during fiscal years ended 1999, 1998 and 1997, respectively. These noncash
compensation charges primarily relate to equity transactions in the Company's
subsidiary, AIR, with respect to common stock issued and stock options granted
to certain employees, consultants and others.

         The Company's research and development expenses were $48,456,824 for
the fiscal year ended in 1999 compared to $31,761,541 and $29,553,988 for the
fiscal years ended in 1998 and 1997, respectively. The increase for fiscal 1999
as compared to fiscal 1998 was mainly the result of expanded clinical and
manufacturing work performed by the Company and the increase in salary and
related benefits and other costs associated with an increase in personnel as the
Company advances its product candidates through development and clinical trials
and prepares for commercial scale manufacturing. In addition, the Company had an
increase in occupancy costs and depreciation and amortization expense related to
the expansion of its Medisorb manufacturing facility in Wilmington, Ohio and the
construction of its new ProLease manufacturing facility in Cambridge,
Massachusetts (see Liquidity and Capital Resources below). The increase for
fiscal 1998 as compared to fiscal 1997 was mainly as a result of an increase in
salary and related benefits and other costs as the Company advanced its product
candidates through development and clinical trials and prepared for process
development and commercial scale manufacturing.

         General and administrative expenses were $14,556,102, $8,374,931 and
$7,516,531 for the fiscal years ended in 1999, 1998 and 1997, respectively. The
increase for fiscal 1999 as compared to fiscal 1998 was mainly the result of an
increase in salary and related benefits and other costs relating primarily to an
increase in the number of employees of the Company, as well as an increase in
professional fees and consulting costs. In addition, the Company recorded
approximately $1.3 million in merger costs as a result of its acquisition of AIR
in February 1999. The increase for fiscal 1998 as compared to fiscal 1997 was
mainly the result of an increase in salary and related benefits and consulting
costs.

         The Company does not believe that inflation and changing prices have
had a material impact on its results of operations.


LIQUIDITY AND CAPITAL RESOURCES

         Cash and cash equivalents and short-term investments were approximately
$163.4 million at March 31, 1999 as compared to $194.3 million at March 31,
1998. The primary uses of cash and investments were to finance the Company's
operations, capital expenditures, the payment for the license from ALZA for the
RingCap and DST technologies and the payment of dividends on the Company's
Preferred Stock. In addition, Investments include $7 million principal amount of
high grade corporate notes with maturities ranging from 13 to 17 months. The
Company invests in cash equivalents, U.S. Government obligations, high grade
corporate notes and commercial paper. The Company's investment objectives taken
as a whole are, first, to assure conservation of capital and liquidity, and
second, to obtain investment income.



                                       42
<PAGE>   43
         During fiscal 1999, the Company amended its loan agreement with a bank
to increase the principal amount of the loan by an aggregate of $20 million and
to grant a security interest in certain building, equipment and leasehold
improvements as security for the entire principal of, and interest on, the loan.

         Subsequent to year end, the Company amended its license agreement with
Genentech, Inc. to expand their collaboration for Nutropin Depot(TM), an
injectable sustained release formulation of Genentech's human growth hormone
based on Alkermes' ProLease drug delivery system. The expanded agreement
includes potential milestone payments to the Company of approximately $40
million. The terms of the collaboration included the purchase by Genentech of
$35 million (3,500 shares) of redeemable convertible exchangeable preferred
stock of the Company (the "1999 Preferred Stock"). The 1999 Preferred Stock is
convertible at Genentech's option into shares of common stock during any period
after September 1, 1999 that the closing price of the Company's common stock is
above $45 per share for at least 10 consecutive trading days. The 1999 Preferred
Stock may be redeemed at any time by the Company at a liquidation preference of
$10,000 per share in cash, common stock or non-voting common stock, at the
Company's option. Dividends on the 1999 Preferred Stock are payable quarterly at
a floating three-month LIBOR rate.

         The Company's research and development costs to date have been financed
primarily by sales of equity securities and payments under research and
development collaborative arrangements. The Company expects to incur significant
additional research and development and other costs, including costs related to
preclinical studies, clinical trials and facilities expansion. Therefore, the
Company expects that its costs, including research and development costs for all
of its product candidates, will exceed revenues significantly for the next few
years, which will result in continuing losses from operations.

         Since the research and development revenue from Clinical Partners ended
during the quarter ended June 30, 1996, Alkermes has been using its own
resources to continue to develop Cereport. The Company is required to fund the
development of Cereport to maintain its option to purchase the limited
partnership interests in Clinical Partners. Effective September 30, 1997, the
Company entered into an agreement with ALZA relating to the development and
commercialization of Cereport. ALZA made a $10 million upfront payment to
Alkermes to fund clinical development of Cereport, of which $5.8 million has
been recorded as deferred revenue at March 31, 1999. In return, ALZA will have
the option to acquire exclusive worldwide commercialization rights to Cereport.
If ALZA exercises its option, ALZA will make additional payments to cover costs
associated with advanced clinical development. If Cereport is commercialized
successfully by ALZA, ALZA will pay the Company certain milestone payments.
Alkermes would be responsible for the manufacturing of Cereport, and the two
companies would share approximately equally in profits from sales of products.

         Capital expenditures were approximately $24.1 million for the year
ended March 31, 1999, principally reflecting the costs of the expansion of the
Wilmington, Ohio facility and related equipment purchases and the cost of
construction of the new commercial scale ProLease manufacturing facility in
Cambridge, Massachusetts, both of which properties were completed in fiscal
1999. The Company's capital expenditures for equipment, facilities and building
improvements have been financed to date primarily with proceeds from bank loans
and the sales of equity securities.


                                       43
<PAGE>   44
         The Company will continue to pursue opportunities to obtain additional
financing in the future. Such financing may be sought through various sources,
including equity offerings, bank borrowings, lease arrangements relating to
fixed assets or other financing methods. The source, timing and availability of
any financings will depend on market conditions, interest rates and other
factors. The Company's future capital requirements will depend on many factors,
including continued scientific progress in its research and development
programs, the magnitude of these programs, progress with preclinical testing and
clinical trials, the time and costs involved in obtaining regulatory approvals,
the costs involved in filing, prosecuting and enforcing patent claims, competing
technological and market developments, the establishment of additional
collaborative arrangements, the cost of manufacturing facilities and of
commercialization activities and arrangements and the cost of product
in-licensing and any possible acquisitions.

         The Company believes its current cash and cash equivalents and
short-term investments, combined with anticipated interest income and research
and development revenues under collaborative arrangements, will be sufficient to
meet its anticipated capital requirements through at least March 31, 2001.

         The Company may need to raise substantial additional funds for
longer-term product development, regulatory approvals and manufacturing or
marketing activities that it might undertake in the future. There can be no
assurance that additional funds will be available on favorable terms, if at all.
If adequate funds are not available, the Company may be required to curtail
significantly one or more of its research and development programs and/or obtain
funds through arrangements with collaborative partners or others that may
require the Company to relinquish rights to certain of its technologies, product
candidates or future products.

         As disclosed in Note 2 to the Consolidated Financial Statements, the
Company's adoption of Statement of Financial Accounting Standards ("SFAS") No.
133, "Accounting for Derivative Instruments and Hedging Activities," during
fiscal 2001 establishes accounting and reporting standards for derivative
instruments, including certain derivative instruments embedded in other
contracts and for hedging activities. The Company has not yet assessed the
impact of SFAS No. 133 on its financial position and results of operations.

YEAR 2000

         The Year 2000 problem concerns the application of computer systems
written using six (e.g., 12/31/99) versus eight (e.g., 12/31/1999) digits to
define the applicable date. This could result, among other things, in computer
systems recognizing "00" as the year 1900 rather than the year 2000. Computer
hardware, software and embedded chip equipment are potentially affected, and, if
such systems and components are not remediated satisfactorily, could lead to
operational interruptions and business misinformation.

         The Company has identified its mission critical and medium priority
internal systems which will require remediation to provide for the Company's
continuing business operations after January 1, 2000. The remaining systems are
considered to be of low priority because they are judged to have no direct
impact on safety or the business. The Company's Year 2000 Compliance Plan
provides for a four-phase process: inventory, assessment, remediation and
preparation of contingency plans.

                                       44
<PAGE>   45

         The initial inventory phase is essentially completed. The assessment
phase is substantially completed, except for information not yet received from
external suppliers, vendors and manufacturers. Progress continues to be made in
the remediation phase of the Company's plan in which systems that are not Year
2000 compliant are repaired, replaced or retired, and remediated systems are
tested and returned to active use. There has been a 50% response rate to the
Company's requests for information sent to vendors and manufacturers of
equipment, hardware and software. Based on the responses received as of June 16,
1999, the Company has confirmed that 4% of its mission critical systems are not
compliant. The Company has requested all suppliers of mission critical equipment
containing embedded chip technology to provide the Company with each supplier's
Year 2000 testing methodology and results and/or the Company has performed
in-house testing on such equipment. For the 4% of noncompliant mission critical
systems, the Company has determined what is required to make the system
compliant and is either in the process of remediation or will begin remediation
soon.

         The Company believes its mission critical and medium priority internal
computer systems will be Year 2000 compliant in a timely manner. However, the
Company's computer systems are complex, highly interdependent and there are a
number of risks associated with the complexity and high degree of integration of
the systems. For example, an incorrect classification of the importance of a
system or systems, or the cumulative effect of a number of low priority systems
that have not been remediated, could result in an unpredicted failure or
shutdown in one or more of the Company's business, processing or manufacturing
systems, which could have a material adverse effect on production or cost of
operations. The Company's current belief is that this has a relatively low
probability of occurring. To minimize these risks, the Company is utilizing its
skilled and knowledgeable internal resources and has employed contract personnel
in its decision-making processes and to perform integrated systems testing.

         The Company is continuing a process of requesting and assessing
compliance information from its key suppliers, including strategic partners and
organizations with which the Company does business. Certain of these suppliers
may refuse to respond to a readiness survey or request for information. It is
possible that these suppliers may, in fact, be prepared to address Year 2000
concerns, but simply refuse to respond. Conversely, various suppliers may
respond that they are Year 2000 ready, when, in fact, they are not ready. As of
June 16, 1999, approximately 83% of key supplier recipients have responded to
the survey. Approximately 80% of those surveyed have responded that they are or
will be Year 2000 compliant on a timely basis.

         If the Year 2000 problem causes suppliers and utility providers to fail
to deliver essential materials and services, multiple disruptions in the
Company's operations, computer infrastructure or telecommunications systems
could result. Because of the inherent uncertainties associated with the Year
2000 problem, including understanding the Year 2000 readiness of these key third
parties, it is not possible to quantify the potential impact at this time.
However, failure of key suppliers, utility providers or the Company to address
properly and timely the Year 2000 problem could have a material adverse effect
on the Company's financial condition, results of operations or liquidity.
Furthermore, there can be no guarantee that any contingency plans developed by
the Company will prevent such failures from having a material adverse effect.
The Company believes that there is a low probability that these multiple
failures are likely to occur.

         Contingency plans are being formulated by each of the Company's various
departments. The plans are to be completed by September 30, 1999 for each of the
Company's mission critical systems. These plans may be updated or revised during
the remainder of 1999. The Company currently expects total external expenditures
to become Year 2000 compliant to be less than $1 million. In addition, the
Company has dedicated significant internal resources, including staff and
equipment, to Year 2000 projects, but does not track such costs and therefore
cannot provide an estimate of the amount of such internal costs. The Company
will fund Year 2000 expenditures from cash and expects that total remediation
costs, including the reallocation of internal resources, will not have a
material adverse effect on the Company's financial condition, results of
operations or liquidity.

         The foregoing information reflects management's best estimates. These
estimates are based upon many assumptions, including: assumptions about cost,
availability and ability of resources to identify and classify systems properly;
properly identifying them as needing remediation; locating, remediating and
modifying affected systems; and making various assessments of Year 2000
readiness of key third parties. Based upon its activities to date, the Company
does not believe that these factors will cause its current cost and timetable
projections to differ significantly from those estimated. However, the Company
cannot reasonably estimate the potential impact on its financial condition,
results of operations or liquidity if critical third parties, including
suppliers and governments, do not become Year 2000 compliant on a timely basis.

ITEM 7A.  QUALITATIVE AND QUANTITATIVE DISCLOSURE ABOUT MARKET RISK

         Our Investments consist of U.S. Treasuries and other government
securities, commercial paper and corporate notes. Substantially all Investments
mature within one year, are not callable by the issuer and have fixed interest
rates. A 10% decline in the average yield of the Investments would not have a
material effect on our results of operations or cash flows. Our debt instruments
approximate fair value and generally have fixed interest rates. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations - Liquidity and Capital Resources."

INDEPENDENT AUDITORS' REPORT

The Board of Directors of Alkermes, Inc.:

We have audited the accompanying consolidated balance sheets of Alkermes, Inc.
and subsidiaries as of March 31, 1999 and 1998, and the related consolidated
statements of operations, comprehensive loss, shareholders' equity, and cash
flows for each of the three years in the period ended March 31, 1999. These
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits. The consolidated financial statements give retroactive effect to the
acquisition of Advanced Inhalation Research, Inc., which has been accounted for
as a pooling of interests as described in Note 3 of notes to the consolidated
financial statements.

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, such consolidated financial statements present fairly, in all
material respects, the financial position of Alkermes, Inc. and subsidiaries as
of March 31, 1999 and 1998, and the results of their operations and their cash
flows for each of the three years in the period ended March 31, 1999, in
conformity with generally accepted accounting principles.

ALKERMES, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
YEARS ENDED MARCH 31, 1999, 1998 AND 1997


1.    FORMATION OF THE COMPANY

      Alkermes, Inc. (the "Company") was incorporated in July 1987 and is a
      leader in the development of products based on sophisticated drug delivery
      technologies. The Company has several areas of focus: (i) controlled,
      sustained release of injectable drugs lasting several days to several
      weeks, utilizing its ProLease(R) and Medisorb(R) technologies; (ii) the
      delivery of drugs into the brain past the blood-brain barrier, utilizing
      the Cereport(TM) technology; (iii) oral delivery of drugs using its
      RingCap(TM) and dose sipping technologies ("DST"); and (iv) the
      development of pharmaceutical products based on proprietary pulmonary drug
      delivery technologies utilizing its Advanced Inhalation Research, Inc.
      ("AIR") technology.

2.    SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

      BASIS OF PRESENTATION - The consolidated financial statements give
      retroactive effect to the acquisition of AIR on February 1, 1999 (see Note
      3), which has been accounted for as a pooling of interests.

      PRINCIPLES OF CONSOLIDATION - The consolidated financial statements
      include the accounts of Alkermes, Inc. and its wholly owned subsidiaries,
      Alkermes Controlled Therapeutics, Inc. ("ACTI"), Alkermes Controlled
      Therapeutics Inc. II ("ACT II"), Alkermes Investments, Inc., Alkermes
      Development Corporation II ("ADC II"), Alkermes Europe, Ltd. and AIR. ADC
      II serves as the one percent general partner of Alkermes Clinical
      Partners, L.P. ("Clinical Partners"), a limited partnership engaged in a
      research and development project with the Company (see Note 8). ADC II's
      investment in Clinical Partners is accounted for under the equity method
      of accounting. Such carrying value was zero at March 31, 1999 and 1998
      (see Note 8). All significant intercompany balances and transactions have
      been eliminated.

      USE OF ESTIMATES - The preparation of the Company's consolidated financial
      statements in conformity with generally accepted accounting principles
      necessarily requires management to make estimates and assumptions that
      affect the reported amounts of assets and liabilities and disclosure of
      contingent assets and liabilities at the date of the consolidated
      financial statements and the reported amounts of revenues and expenses
      during the reporting period. Actual results could differ from those
      estimates.

      FAIR VALUE OF FINANCIAL INSTRUMENTS - Statement of Financial Accounting
      Standards ("SFAS") No. 107, "Disclosures About Fair Value of Financial
      Instruments," requires disclosure of the fair value of certain financial
      instruments. The carrying amounts of cash, cash equivalents, accounts
      payable and accrued expenses approximate fair value because of their
      short-term nature. Marketable equity securities are recorded in the
      consolidated financial statements at fair value. The carrying amounts of
      the Company's debt instruments approximate fair value.


                                       55
<PAGE>   56
2.    SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

      NET LOSS PER SHARE - Basic and diluted net loss per share are computed
      using the weighted average number of common shares outstanding during the
      period.

      The Company accounts for earnings per share in accordance with the
      provisions of SFAS No. 128, "Earnings per Share." Basic earnings per share
      exclude any dilutive effect from stock options, warrants and convertible
      exchangeable preferred stock. The Company continues to be in a net loss
      position and, therefore, diluted earnings per share is the same amount as
      basic earnings per share. Stock options and warrants (see Notes 8 and 11)
      were not included in the computation of diluted earnings per share because
      to do so would have been antidilutive for all periods presented.

      RESEARCH AND DEVELOPMENT REVENUES - Research and development revenues are
      recorded as services are performed. Revenue earned upon the achievement of
      research and development milestones is recorded when achieved.

      RESEARCH AND DEVELOPMENT EXPENSES - Research and development expenses are
      charged to operations as incurred.

      NONCASH COMPENSATION EXPENSE - Noncash compensation expense primarily
      relates to equity transactions in the Company's subsidiary, Advanced
      Inhalation Research, Inc., and has been recorded at the difference between
      fair market value at the measurement date and the issuance price for
      common stock issued and stock options granted to certain employees,
      consultants and others. In addition, the Company has also recorded noncash
      charges for stock options and stock awards granted to certain other
      employees, consultants and others for the difference between fair market
      value at the measurement date and the issuance price. The measurement date
      is generally the issuance date for employees and the vesting date for
      consultants. The noncash charge has been recorded in the statements of
      operations upon issuance or over the vesting period of the common stock,
      stock option or award.

      INCOME TAXES - The Company accounts for income taxes under SFAS No. 109,
      "Accounting for Income Taxes." SFAS No. 109 requires the recognition of
      deferred tax assets and liabilities relating to the expected future tax
      consequences of events that have been recognized in the Company's
      consolidated financial statements and tax returns (see Note 7).

      CASH EQUIVALENTS - Cash equivalents, with purchased maturities of three
      months or less, consist of money market accounts, mutual funds and an
      overnight repurchase agreement. The repurchase agreement is fully
      collateralized by U.S. Government securities.

      INVESTMENTS - Debt securities that the Company has the positive intent and
      ability to hold to maturity are reported at amortized cost and are
      classified as "held-to-maturity."

      All Short-Term Investments and Investments consist of U.S. Treasury and
      other government securities, commercial paper and corporate notes and are
      classified as "held-to-maturity" and reported at amortized cost.
      Short-Term Investments have maturity dates within one year of the balance
      sheet date. Investments classified as long-term have maturity dates up to
      sixteen months from March 31, 1999 and include securities held as
      collateral. The carrying value of all Short-Term Investments and
      Investments, individually and in the aggregate, approximated market value
      at March 31, 1999 and 1998.


                                       56
<PAGE>   57
2.    SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

      PROPERTY, PLANT AND EQUIPMENT - Property, plant and equipment are recorded
      at cost. Depreciation and amortization are provided using the
      straight-line method over the following estimated useful lives of the
      assets: buildings - 25 years; furniture, fixtures and equipment - 3 to 7
      years; or, in the case of leasehold improvements, over the lease terms - 2
      to 10 years.

      DEFERRED REVENUE - SHORT-TERM - During fiscal 1998, the Company received a
      $10,000,000 upfront payment from ALZA Corporation ("ALZA") to fund
      clinical development of Cereport. This amount has been recorded as
      deferred revenue and is being amortized based on actual costs incurred for
      the clinical development of Cereport. In addition, the Company received
      prepayments for research and development costs under other collaborative
      research projects which are being amortized over the minimum term of the
      agreements using the straight-line method.

      DEFERRED REVENUE - LONG-TERM - During fiscal 1996, the Company received a
      $5,000,000 prepayment of royalties under a collaborative agreement. This
      amount was recorded as deferred revenue at March 31, 1998 and accrued
      interest (included in other long-term liabilities) at a rate (6.16875% at
      March 31, 1998) equal to 0.20% above the one-year LIBOR rate. During
      fiscal 1999, the principal and accrued interest were converted to a note
      payable (see Note 6).

      PURCHASED PATENTS - Purchased patents, included in other assets, are
      amortized on a straight-line basis over a period of five years.

      DEFERRED COMPENSATION - Deferred compensation is related to awards under
      the Company's 1991 Restricted Common Stock Award Plan, compensatory stock
      options and common stock and is amortized over vesting periods ranging
      from one to five years.

      401(k) PLAN - The Company's 401(k) Retirement Savings Plan (the "401(k)
      Plan") covers substantially all of its employees. Eligible employees may
      contribute up to 17% of their eligible compensation, subject to certain
      Internal Revenue Service limitations. The Company began matching a portion
      of employee contributions on April 1, 1998. The match is equal to 50% of
      the first 6% of deferrals and is fully vested when made. During fiscal
      1999, the Company provided approximately $307,000 to match employee
      deferrals under the 401(k) Plan.

      RECLASSIFICATIONS - Certain reclassifications have been made in fiscal
      1998 and 1997 to conform to the presentation used in fiscal 1999.

      COMPREHENSIVE INCOME - The Company adopted SFAS No. 130, "Reporting
      Comprehensive Income," on April 1, 1998. SFAS No. 130 requires companies
      to display comprehensive income and its components as part of the
      Company's full set of consolidated financial statements. Comprehensive
      income is comprised of net income and other comprehensive income. The
      measurement and presentation of net loss did not change. Other
      comprehensive income includes certain changes in equity of the Company
      that are excluded from the net loss. Specifically, SFAS No. 130 requires
      unrealized holding gains and losses on the Company's available-for-sale
      securities and cumulative foreign currency translation adjustments, which
      are currently reported in shareholders' equity, to be included in other
      comprehensive income.

2.    SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

      SEGMENTS - The Company adopted SFAS No. 131, "Disclosures about Segments
      of an Enterprise and Related Information," on April 1, 1998. Under SFAS
      No. 131, the Company's operations are treated as one operating segment
      reporting to the chief operating decision-makers of the Company.
      Accordingly, the adoption of SFAS No. 131 did not have an effect on the
      Company's financial position or results of operations or its footnotes
      disclosures.

      NEW ACCOUNTING PRONOUNCEMENTS - In June 1998, the Financial Accounting
      Standards Board ("FASB") issued SFAS No. 133, "Accounting for Derivative
      Instruments and Hedging Activities," effective for fiscal years beginning
      after June 15, 1999. SFAS No. 133 establishes accounting and reporting
      standards for derivative instruments, including certain derivative
      instruments embedded in other contracts and for hedging activities. It
      requires companies to recognize all derivatives as either assets or
      liabilities on the balance sheet and to measure those instruments at fair
      value. Gains or losses resulting from changes in the values of those
      derivatives would be accounted for depending on the use of the derivative
      and whether it qualifies for hedge accounting under SFAS No. 133.
      Management has not yet assessed the impact of SFAS No. 133 on its
      financial position and results of operations.

3.    ACQUISITION OF ADVANCED INHALATION RESEARCH, INC. ("AIR")

      In February 1999 the Company acquired AIR, a private company focused on
      the development of pharmaceutical products based on proprietary pulmonary
      drug delivery technologies. The acquisition was accomplished by merging a
      newly formed, wholly owned subsidiary of the Company with and into AIR and
      has been accounted for as a tax-free pooling of interests. No adjustments
      to conform accounting policies of AIR were required. The Company has
      recorded merger costs of approximately $1,300,000 which have been charged
      to operations primarily in the quarter ended March 31, 1999. Pursuant to
      the merger agreement, the Company issued 3,680,508 shares of its common
      stock to the stockholders of AIR (see Note 5). An additional 119,474
      shares of common stock were reserved for issuance upon the exercise of
      unvested stock options granted to employees and consultants of AIR which
      were assumed by the Company.

      Revenues and net loss of AIR for the periods before the merger were
      approximately $40,000 and $2,811,000, respectively, for the period from
      May 7, 1997 (date of incorporation) through March 31, 1998 and were
      $1,286,000 and $16,033,000, respectively, for the period April 1, 1998 to
      February 1, 1999, the date the merger was consummated. For the same
      periods, the net loss included noncash compensation charges of
      approximately $2,100,000 and $13,115,000, respectively.

4.    ALZA AGREEMENT

      In April 1998, Alkermes entered into an exclusive license agreement with
      ALZA, a pharmaceutical and drug delivery company, for two of ALZA's oral
      drug delivery technologies: RingCap and DST. The Company also acquired
      equipment to be used in the development of the technologies. A
      nonrecurring charge of approximately $3,200,000 for technology licensed
      but not yet commercially viable was recorded by the Company at the
      acquisition date. This charge represents that portion of the acquisition
      price of the acquired technology that was allocated to in-process research
      and development.

5.    SHAREHOLDERS' EQUITY

      RESTRICTED STOCK PURCHASE AGREEMENTS/COMMON STOCK - During fiscal 1999,
      the Company issued 3,680,508 shares of its common stock in conjunction
      with its acquisition of AIR. Of these shares, 2,401,115 shares of common
      stock were issued to key employees and consultants of AIR and are subject
      to restricted stock purchase agreements. The Company assumed these
      restricted stock purchase agreements entered into by AIR. The agreements
      state that if the consulting or employment relationship terminates within
      four years of issuance, the Company shall have the right, but not the
      obligation, to repurchase the nonvested shares from the shareholder at the
      share price initially paid by the shareholder. The restricted stock vests
      quarterly over a four-year period at different amounts for each
      shareholder. At March 31, 1999 and 1998, approximately 1,060,000 and
      447,000 shares of restricted stock, respectively, had vested.

      In May 1996, the Company completed a direct public offering of 2,300,000
      shares of its common stock at $10.00 per share. Net proceeds to the
      Company were approximately $22,900,000.

      In March 1997, the Company completed a private placement of 2,000,000
      shares of its common stock at $25.00 per share. Net proceeds to the
      Company were approximately $49,700,000.

      PREFERRED STOCK - In March 1998, the Company completed a private placement
      of 2,300,000 shares of its convertible exchangeable preferred stock (the
      "Preferred Stock") at $50.00 per share. Net proceeds to the Company were
      approximately $110,500,000.

      The Preferred Stock is convertible at the option of the holder at any
      time, unless previously redeemed or exchanged, into the Company's common
      stock at an initial conversion rate of 1.6878 shares of common stock for
      each share of Preferred Stock. The initial conversion rate is subject to
      adjustment in certain events. The Company has reserved 3,881,940 shares of
      its common stock for issuance upon conversion.

      Dividends on the Preferred Stock will be cumulative from the date of
      original issue and have been paid quarterly, commencing June 1, 1998 and
      payable each September 1, December 1, March 1 and June 1 thereafter, at
      the annual rate of $3.25 per share of Preferred Stock. Prior to March 6,
      2001, the Preferred Stock is not redeemable at the option of the Company.
      Thereafter the Preferred Stock is redeemable at the option of the Company,
      in whole or in part, at declining redemption prices, together with accrued
      dividends. If redeemed during the 12-month period beginning March 1
      (beginning March 6, 2001 and ending on February 28, 2002, in the case of
      the first such period) the per share redemption prices are $52.275 in
      2001, $51.950 in 2002, $51.625 in 2003, $51.300 in 2004, $50.975 in 2005,
      $50.650 in 2006, $50.325 in 2007 and $50 at March 1, 2008 and thereafter.
      The Preferred Stock has a liquidation preference of $50 per share, plus
      accrued and unpaid dividends.

      The Preferred Stock is exchangeable, in whole but not in part, at the
      option of the Company on any dividend payment date beginning March 1, 1999
      (the "Exchange Date") for the Company's 6-1/2% Convertible Subordinated
      Debentures (the "Debentures") at the rate of $50 principal amount of
      Debentures for each share of Preferred Stock. The Debentures, if issued,
      will mature on the tenth anniversary of the Exchange Date and will contain
      conversion and optional redemption provisions substantially identical to
      those of the Preferred Stock.

</TABLE>

      The first bank note listed above is secured by a building and real
      property pursuant to a mortgage and certain of the Company's equipment
      pursuant to security agreements. One tranche of this bank loan totalling
      $11,000,000 is payable in seventeen equal quarterly installments of
      $275,000 and a balloon payment of $6,325,000 due on September 30, 2003.
      The loan is also secured by cash collateral (included in long-term
      investments at March 31, 1999) having a minimum market value of the lesser
      of $1,000,000 or the outstanding principal amount of the loan. Under the
      terms of the loan agreement, the Company is required to maintain a minimum
      unencumbered balance of cash and permitted investments and a minimum ratio
      of unencumbered cash and net quick assets to total liabilities as well as
      a minimum consolidated capital base.

      The second bank note listed above requires the Company to maintain a
      minimum net worth, a maximum ratio of total liabilities to net worth, a
      minimum current ratio and a minimum unencumbered balance of cash and
      permitted investments. Upon the breach of any of these financial covenants
      or the occurrence of any other event of default under the loan agreement,
      the Company would be required to deposit an amount equal to the then
      outstanding principal balance of the loan plus three months' interest into
      a restricted account at the bank. Under the terms of the loan agreement,
      the bank would have the right to liquidate such account and apply the
      proceeds to repayment of the loan if the Company's unencumbered cash and
      investment balance falls below $5,000,000.

6.    LONG-TERM OBLIGATIONS (CONTINUED)

      In January 1995, the Company borrowed $3,500,000 from a corporate partner.
      The principal amount of the loan, together with interest, is payable in
      the Company's common stock or cash, at the Company's option.

      In October 1998, the Company converted a prepayment of royalties from a
      former corporate partner, plus accrued interest, to a promissory note in
      the principal amount of $5,983,292 as a result of the discontinuation of a
      collaboration. The principal amount of the note, together with interest,
      is payable in the Company's common stock or cash, at the Company's option.

      At March 31, 1999, the maturities of the long-term obligations are as
      follows:

7.    INCOME TAXES

      At March 31, 1999, the Company has approximately $76,995,000 of net
      operating loss ("NOL") carryforwards for U.S. federal income tax purposes
      and approximately $7,884,000 of research and development tax credits
      available to offset future federal income tax, subject to limitations for
      alternative minimum tax. The NOL and research and development credit
      carryforwards are subject to examination by the tax authorities and expire
      in various years from 2002 through 2019.

      The components of the net deferred income tax assets at March 31 are as
      follows:

      The valuation allowance has been provided because of the uncertainty of
      realizing the future benefits of the net deferred income tax assets. The
      valuation allowance increased by $4,959,000 from March 31, 1997 to March
      31, 1998.

7.    INCOME TAXES (CONTINUED)

      The ACTI NOL and research and development credit carryforwards (included
      in the table above) of approximately $4,780,000 and $790,000,
      respectively, acquired from Enzytech, Inc. are only available to offset
      future taxable income of ACTI.

8.    RELATED-PARTY TRANSACTIONS

      On April 10, 1992, the Company and Clinical Partners, a limited
      partnership of which ADC II is the general partner, sold in a private
      placement (i) 920 Class A units, each unit (a "Class A Unit") consisting
      of one Class A limited partnership interest in Clinical Partners, a 1992
      warrant (a "Class A 1992 Warrant") to purchase 2,800 shares of the
      Company's common stock and a 1995 warrant (a "Class A 1995 Warrant") to
      purchase 300 shares of the Company's common stock; and (ii) one Class B
      unit (the "Class B Unit"), consisting of one Class B limited partnership
      interest in Clinical Partners, a 1992 warrant (the "Class B 1992 Warrant")
      to purchase 5,600 shares of the Company's common stock and a 1995 warrant
      (the "Class B 1995 Warrant") to purchase 600 shares of the Company's
      common stock. The purchase price was $50,000 for each Class A Unit and
      $100,000 for the Class B Unit.

      The Company completed an exchange offer on January 27, 1995 with respect
      to the warrants issued in 1992 in connection with the formation of
      Clinical Partners. Pursuant to the exchange offer, Class A limited
      partners had the option to exchange both their Class A 1992 Warrants and
      Class A 1995 Warrants for a new 1994 Class A Warrant to purchase, at $5.00
      per share, and during the period beginning on April 1, 1995 and ending on
      March 31, 2000, 1,700 shares of the Company's common stock for every 3,100
      shares of common stock issuable upon exercise of the Class A 1992 Warrant
      and Class A 1995 Warrant exchanged therefor. The Class B limited partner
      had the option to exchange both the Class B 1992 and Class B 1995 Warrants
      for a new 1994 Class B Warrant to purchase 3,400 shares of the Company's
      common stock at $5.00 per share. The 1994 Class B Warrant is exercisable
      during the same period as the 1994 Class A Warrants.

      The net proceeds of the offering were used primarily to fund the further
      development and clinical testing of a family of molecules designated by
      the Company as Receptor-Mediated Permeabilizers(TM) ("RMPs"(TM)),
      including Cereport, for human pharmaceutical use in the United States and
      Canada. Proprietary RMP(TM) molecules developed by the Company may enhance
      the passage of small drug molecules from the bloodstream into the brain.
      Pursuant to the Product Development Agreement entered into in March 1992,
      the Company licensed to Clinical Partners certain of its technology
      relating to RMPs. Research and development of RMPs is being conducted by
      the Company for Clinical Partners pursuant to the Product Development
      Agreement. The Company was reimbursed by Clinical Partners for its actual
      costs incurred in conducting such research and development and also
      received a management fee of 10% of such costs. Such funding ended during
      the quarter ended June 30, 1996. None of the partners of Clinical Partners
      is obligated to make any further capital contributions. Since the funding
      was not sufficient to complete clinical trials and seek regulatory
      approval of Cereport, Alkermes has used its own resources, and intends to
      continue to use its own resources, to develop Cereport. Alkermes has
      obtained and intends to continue to obtain such resources through equity
      offerings, bank borrowings and collaborative arrangements. The Company is
      required to fund the development of Cereport to maintain its Purchase
      Option, as defined below, with the limited partners.

      Clinical Partners has granted the Company an exclusive interim license to
      manufacture and market RMPs for human pharmaceutical use in the United
      States and Canada. Upon the first marketing approval of an RMP product by
      the United States Food and Drug Administration, the Company is obligated
      to make a payment (approximately $8,300,000) to Clinical Partners equal to
      20% of the aggregate capital contributions of all partners (the "milestone
      payment"). Additionally, the Company will make royalty payments to
      Clinical Partners equal to 12% of United States and Canadian revenues and
      10% of European revenues, in certain circumstances, from any sales of RMPs
      by the Company. The interim license will terminate if the Company does not
      exercise the Purchase Option.

      The 1992 Warrants, the 1995 Warrants (collectively, the "Class A
      Warrants"), the Class B 1992 Warrant and the Class B 1995 Warrant
      (collectively, the "Class B Warrants") were issued by the Company in
      consideration of the grant by each limited partner to the Company of an
      option to purchase (the "Purchase Option"), under certain circumstances,
      the limited partnership interests in Clinical Partners held by such
      limited partner. Upon exercise of such Purchase Option, each Class A
      limited partner will be entitled to receive an initial payment, at the
      Company's option, of $40,000 in cash or approximately $42,100 in the
      Company's common stock, as well as certain additional payments (which are
      subject to certain limitations) based on the Company's net revenues from
      sales of RMPs in the United States, Canada and Europe as follows:

      -    12% of net revenues to the Company on sales of RMPs in the United
           States and Canada and 10% of net revenues to the Company on sales of
           RMPs in Europe, until each Class A limited partner has received an
           aggregate of $400,000 per interest from the initial payment and the
           royalty stream; thereafter,

      -    9% of net revenues to the Company on sales of RMPs in the United
           States, Canada and Europe, until each Class A limited partner has
           received an aggregate of $500,000 per interest from the initial
           payment and the royalty stream; and thereafter,

      -    4% of net revenues to the Company on sales of RMPs in the United
           States, Canada and Europe.

      Royalties on sales of RMPs in Europe will be payable only to the extent
      necessary to pay projected distributions in any year. If royalties on
      sales of RMPs in the United States and Canada in any year equal or exceed
      the projected distributions for such year, no royalties on European sales
      will be paid in that year.

      At March 31, 1999, warrants to purchase shares of the Company's common
      stock were outstanding as follows:

9.    RESEARCH AND DEVELOPMENT ARRANGEMENTS

      The Company has entered into several collaborative agreements with
      corporate partners (the "Partners") to provide research and development
      activities relating to the partners' products. In connection with these
      agreements, the Company has granted certain licenses or the right to
      obtain certain licenses to technology developed by the Company. In return
      for such grants, the Company will receive certain payments upon the
      achievement of certain milestones and will receive royalties on sales of
      products developed under the terms of the agreements. Additionally, the
      Company has or may obtain the right to manufacture and supply products
      developed under certain of these agreements.

      During fiscal 1999, 1998 and 1997, research and development revenue under
      collaborative arrangements from Genentech, Inc. ("Genentech") amounted to
      33%, 30% and 28%, and Johnson & Johnson amounted to 28%, 36% and 47%,
      respectively, of total revenues.

10.   COMMITMENTS

      LEASE COMMITMENTS - The Company leases certain of its offices, research
      laboratories and manufacturing facilities under operating leases with
      initial terms of two to ten years expiring between 2001 and 2008. Several
      of the leases contain provisions for extensions for up to ten years. Total
      annual future minimum lease payments are as follows:

</TABLE>

      Rent expense charged to operations was approximately $4,237,000,
      $3,618,000 and $3,342,000 for the years ended March 31, 1999, 1998 and
      1997, respectively.

      Additionally, a U.S. Treasury Bill with a total principal amount of
      $250,000 is being held by a bank in the Company's name as a security
      deposit on the leases and, accordingly, has been classified as a long-term
      investment at March 31, 1999.

      LICENSE AND ROYALTY COMMITMENTS - The Company has entered into license
      agreements with certain corporations and universities which require the
      Company to pay annual license fees and royalties based on a percentage of
      revenues from sales of certain products and royalties from sublicenses
      granted by the Company. Amounts paid under these agreements were
      approximately $127,000, $112,000 and $92,000 for the years ended March 31,
      1999, 1998 and 1997, respectively.

11.   STOCK OPTIONS AND AWARDS

      The Company's Stock Option Plans (the "Plans") include the Amended and
      Restated 1989 Non-Qualified Stock Option Plan (the "1989 Plan"), the
      Amended and Restated 1990 Omnibus Stock Option Plan, as amended (the "1990
      Plan"), the 1992 Non-Qualified Stock Option Plan (the "1992 Plan") and the
      1998 Equity Incentive Plan (the "1998 Plan") which provide for the
      granting of stock options to employees, officers and directors of, and
      consultants to, the Company. In addition, the Stock Option Plan for
      Non-Employee Directors (the "Director Plan") provides for the granting of
      stock options to nonemployee directors of the Company. Nonqualified
      options to purchase up to 225,000 shares of the Company's common stock may
      be granted under the 1989 Plan, nonqualified and incentive options to
      purchase up to 3,250,000 shares of the Company's common stock may be
      granted under the 1990 Plan, nonqualified options to purchase up to
      1,000,000 shares of the Company's common stock may be granted under the
      1992 Plan, nonqualified and incentive stock options and restricted stock
      to purchase up to 591,487 shares may be granted under the 1998 Plan and
      nonqualified options to purchase up to 150,000 shares of the Company's
      common stock may be granted under the Director Plan. Unless sooner
      terminated, the 1989 Plan will terminate on July 18, 1999, the 1990 Plan
      will terminate on September 19, 2000, the 1992 Plan will terminate on
      November 11, 2002, the 1998 Plan will terminate on April 1, 2008 and the
      Director Plan will terminate on March 18, 2006. The Company has reserved a
      total of 4,211,033 shares of common stock for options outstanding and
      available for future grant under the six plans.

<PAGE>   66
11.   STOCK OPTIONS AND AWARDS (CONTINUED)

      The Compensation Committee of the Board of Directors administers the Plans
      and determines who is to receive options and the exercise price and terms
      of such options. The Compensation Committee has delegated its authority to
      the Compensation Sub-Committee to make grants and awards under the Plans
      to "officers." The Board of Directors administers the Director Plan. The
      option exercise price of stock options granted under the 1989 Plan, the
      1990 Plan, the 1998 Plan and the Director Plan may not be less than 100%
      of the fair market value of the common stock on the date of grant. Under
      the terms of the 1992 Plan, the option exercise price may be below the
      fair market value, but not below par value, of the underlying stock at the
      time the option is granted.

      The 1989 Plan, the 1990 Plan and the 1992 Plan also provide that the
      Compensation Committee may grant Limited Stock Appreciation Rights
      ("LSARs") with respect to all or any portion of the shares covered by
      stock options granted to directors and executive officers. LSARs may be
      granted with the grant of a nonqualified stock option or at any time
      during the term of such option but may only be granted with the grant of
      an incentive stock option. The grant of LSARs will not be effective until
      six months after their date of grant. Upon the occurrence of certain
      triggering events, including a change of control, the options with respect
      to which LSARs have been granted shall become immediately exercisable and
      the persons who have received LSARs will automatically receive a cash
      payment in lieu of shares. At March 31, 1999, there are 400,750 LSARS
      outstanding which have been granted under the 1990 Plan. No LSARS were
      granted during fiscal 1999, 1998 and 1997.

      The Company has also adopted the 1991 Restricted Common Stock Award Plan
      (the "Award Plan"). The Award Plan provides for the award to certain
      eligible employees, officers and directors of, and consultants to, the
      Company of up to a maximum of 250,000 shares of common stock. The Award
      Plan is administered by the Compensation Committee. Awards generally vest
      over five years. During fiscal 1999, 1998 and 1997, no shares of common
      stock were awarded under the Award Plan and 2,850, 2,400 and 2,400 shares,
      respectively, ceased to be subject to forfeiture and were issued. In
      addition, 2,000, 1,800 and zero shares were canceled during the years
      ended March 31, 1999, 1998 and 1997, respectively. At March 31, 1999, 1998
      and 1997 there were 30,400, 35,250 and 35,200 awards outstanding under the
      Award Plan, respectively. The Award Plan will terminate on November 15,
      2001, unless sooner terminated by the Board of Directors.

      The Company has elected to continue to follow Accounting Principles Board
      ("APB") No. 25 for accounting for its employee stock options. Under APB
      No. 25, no compensation expense is recognized with respect to the grant of
      any stock options to employees if the exercise price of the Company's
      employee stock options equals the fair market price of the underlying
      stock on the date the option is granted.

      Pro forma information regarding net loss and basic and diluted loss per
      common share in fiscal 1999, 1998 and 1997 has been determined as if the
      Company had accounted for its employee stock options under the fair value
      method prescribed by SFAS No. 123. The resulting effect on pro forma net
      loss and basic and diluted loss per common share is not necessarily likely
      to be representative of the effects on net loss and basic and diluted loss
      per common share on a pro forma basis in future years, due to (i) grants
      made prior to fiscal 1996 being excluded from the calculation and (ii) the
      uncertainty regarding the magnitude of future grants. The fair value of
      options was estimated at the date of grant using the Black-Scholes option
      pricing model with the following weighted average assumptions: risk-free
      interest rates ranging from 4.79% - 5.68% for fiscal 1999, 5.56% - 5.90%
      for fiscal 1998 and 6.60% - 6.84% for fiscal 1997; dividend yields of 0%
      in fiscal 1999, 1998 and 1997; volatility factors of the expected market
      price of the Company's common stock of 67% in fiscal 1999, 65% in fiscal
      1998 and 67% in fiscal 1997; and a weighted average expected life of 4
      years in fiscal 1999 and 5 years in fiscal years 1998 and 1997. Using the
      Black-Scholes option pricing model, the weighted average fair value of
      options granted in fiscal 1999, 1998 and 1997 was $7.90, $10.39 and $8.00,
      respectively.

12.   SUBSEQUENT EVENT

      GENENTECH AGREEMENT, 1999 PREFERRED STOCK - In April 1999, the Company
      amended its license agreement with Genentech to expand their collaboration
      for Nutropin Depot(TM), an injectable sustained release formulation of
      Genentech's human growth hormone based on Alkermes' ProLease drug delivery
      system. Under the agreement, the companies will conduct expanded
      development activities, including clinical trials in an additional
      indication, process and formulation development and manufacturing. The
      agreement includes potential milestone payments to the Company of
      approximately $40 million.

      The terms of the collaboration included the purchase by Genentech of $35
      million (3,500 shares) of newly issued redeemable convertible exchangeable
      preferred stock of the Company (the "1999 Preferred Stock"). The 1999
      Preferred Stock is convertible at Genentech's option into shares of common
      stock and non-voting common stock during any period after September 1,
      1999 that the closing price of the Company's common stock is above $45 per
      share for at least 10 consecutive trading days. The Company has the option
      to redeem the 1999 Preferred Stock, in whole or in part, at any time at
      the redemption price of $10,000 per share plus accrued and unpaid
      dividends (the "1999 Redemption Price"). There will be a mandatory
      redemption of any outstanding shares of the 1999 Preferred Stock on
      January 1, 2009 at the 1999 Redemption Price. The Company has the option
      to pay the 1999 Redemption Price in cash, common stock or non-voting
      common stock.

      The 1999 Preferred Stock will be junior to the Company's outstanding $115
      million of convertible exchangeable preferred stock that was issued by the
      Company in March 1998. The 1999 Preferred Stock has a liquidation
      preference of $10,000 per share, plus accrued and unpaid dividends.
      Dividends on the 1999 Preferred Stock are payable quarterly at a floating
      three-month LIBOR rate.

                                   UNDERTAKING

         For the purposes of complying with the amendments to the rules
governing Form S-8 (effective July 13, 1990) under the Securities Act of 1933,
the undersigned Registrant hereby undertakes as follows, which undertaking shall
be incorporated by reference into Registrant's Registration Statements on Form
S-8, Nos. 33-44752, 33-58330, 33-97468, 333-13283, 333-50357 and 333-71011 and
on Form S-3, Nos. 333-75645, 333-75649, 333-50157, 333-19955 and 33-90736.

         Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the Registrant, the Registrant has been advised that in the opinion of the
Securities and Exchange Commission such indemnification is against public policy
as expressed in the Securities Act of 1933 and is, therefore, unenforceable. In
the event that a claim for indemnification against such liabilities (other than
the payment by the Registrant of expenses incurred or paid by a director,
officer or controlling person of the Registrant in the successful defense of any
action, suit or proceeding) is asserted by such director, officer or controlling
person in connection with the securities being registered, the Registrant will,
unless in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the Act and
will be governed by the final adjudication of such issue.

                                        3


<PAGE>   4
directors, whether at all times or only so long as no senior class of stock has
such voting power by reason of any contingency.

                  "TRADING DAY" shall mean (x) if the applicable security is
listed or admitted for trading on the New York Stock Exchange or another
national security exchange, a day on which the New York Stock Exchange or
another national security exchange is open for business or (y) if the applicable
security is quoted on The Nasdaq National Market, a day on which trades may be
made thereon or (z) if the applicable security is not so listed, admitted for
trading or quoted, any day other than a Saturday or Sunday or a day on which
banking institutions in the State of New York are authorized or obligated by law
or executive order to close.

                  "TRANSFER AGENT" means BankBoston, N.A. or such other agent or
agents of the Company as may be designated by the Board of Directors of the
Company as the transfer agent for the 1999 Preferred Stock.

         3.       DIVIDENDS.

                  (a)      Holders of 1999 Preferred Stock are entitled to
receive, when, as and if declared by the Board of Directors, out of the funds of
the Company legally available therefor, cash dividends per share of 1999
Preferred Stock at the LIBOR Rate, payable on March 1, June 1, September 1 and
December 1 (each a "Dividend Payment Date"), commencing June 1, 1999 (and, in
the case of any accrued but unpaid dividends, at such additional times and for
such interim periods, if any, as determined by the Board of Directors). If June
1, 1999 or any other Dividend Payment Date shall be on a day other than a
Business Day, then the Dividend Payment Date shall be on the next succeeding
Business Day. Dividends on the 1999 Preferred Stock will be cumulative from the
Issue Date, whether or not in any Dividend Period or Periods there shall be
funds of the Company legally available for the payment of such dividends and
whether or not such dividends are declared, and will be payable to holders of
record as they appear on the stock books of the Company on such record dates
(each such date, a "Dividend Payment Record Date"), which shall be not more than
60 days nor less than 10 days preceding the Dividend Payment Dates thereof, as
shall be fixed by the Board of Directors. Dividends on the 1999 Preferred Stock
shall accrue (whether or not declared) on a daily basis from the Issue Date, and
accrued dividends for each Dividend Period shall accumulate to the extent not
paid on the Dividend Payment Date first following the Dividend Period for which
they accrue. As used herein, the term "accrued" with respect to dividends
includes both accrued and accumulated dividends.

                  (b)      The amount of dividends payable for each Dividend
Period on the 1999 Preferred Stock shall be computed on the basis of actual days
elapsed. Holders of shares of 1999 Preferred Stock called for redemption on a
redemption date falling between the close of business on a Dividend Payment
Record Date and the opening of business on the corresponding Dividend Payment
Date shall, in lieu of receiving such dividend on the




                                        4


<PAGE>   5
Dividend Payment Date fixed therefor, receive such dividend payment together
with all other accrued and unpaid dividends on the date fixed for redemption
(unless such holders convert such shares in accordance with Section 7 hereof).
Holders of shares of 1999 Preferred Stock shall not be entitled to any
dividends, whether payable in cash, property or stock, in excess of cumulative
dividends, as herein provided. No interest, or sum of money in lieu of interest,
shall be payable in respect of any dividend payment or payments on the 1999
Preferred Stock which may be in arrears.

                  (c)      Notwithstanding the accumulation of dividends on the
1999 Preferred Stock, whether or not declared or paid, the Company may (i)
declare or pay or set apart for payment dividends, in cash or shares of capital
stock, on any class or series of stock of the Company; (ii) redeem, purchase or
otherwise acquire for any consideration (or any monies paid to or made available
for a sinking fund or otherwise for the purchase or redemption of any shares of
any such stock) any other capital stock of the Company.

         4.       LIQUIDATION PREFERENCE.

                  (a)      In the event of any voluntary or involuntary
dissolution, liquidation or winding up of the Company (for the purposes of this
Section 4, a "Liquidation"), before any distribution of assets shall be made to
the holders of Common Stock or the holders of any other stock of the Company
that ranks junior to the 1999 Preferred Stock upon Liquidation, the holder of
each share of 1999 Preferred Stock then outstanding shall be entitled to be paid
out of the assets of the Company available for distribution to its shareholders,
an amount equal to liquidation preference of $10,000 per share plus all
dividends accrued and unpaid on such share up to the date of distribution of the
assets of the Company to the holders of 1999 Preferred Stock, and the holders of
any class or series of preferred stock ranking on a parity with the 1999
Preferred Stock as to Liquidation shall be entitled to receive the full
respective liquidation preferences (including any premium) to which they are
entitled and shall receive all accrued and unpaid dividends with respect to
their respective shares through and including the date of distribution.

                  (b)      If upon any Liquidation of the Company, the assets
available for distribution to the holders of 1999 Preferred Stock and any other
stock of the Company ranking on a parity with the 1999 Preferred Stock upon
Liquidation which shall then be outstanding shall be insufficient to pay the
holders of all outstanding shares of 1999 Preferred Stock and all other such
parity stock the full amounts (including all dividends accrued and unpaid) of
the liquidating distribution to which they shall be entitled, then the holders
of each series of such stock will share ratably in any such distribution of
assets first in proportion to their respective liquidation preferences
(including accrued and unpaid dividends in the case of 1999 Preferred Stock)
until such preferences are paid in full, and then in proportion to their
respective amounts of accrued but unpaid dividends. After payment of any such
liquidating preference and accrued dividends, the holders of shares of 1999
Preferred Stock will not be entitled to any further participation in any
distribution of assets by the Company.



                                        5


<PAGE>   6
                  (c)      For purposes of this Section 4, a Liquidation shall
not include (i) any consolidation or merger of the Company with or into any
other corporation, (ii) any liquidation, dissolution, winding up or
reorganization of the Company immediately followed by reincorporation of another
corporation or (iii) a sale or other disposition of all or substantially all of
the Company's assets to another corporation unless in connection therewith the
Liquidation of the Company is specifically approved.

                  (d)      The holder of any shares of 1999 Preferred Stock
shall not be entitled to receive any payment owed for such shares under this
Section 4 until such holder shall cause to be delivered to the Company (i) the
certificate(s) representing such shares of 1999 Preferred Stock and (ii)
transfer instrument(s) satisfactory to the Company and sufficient to transfer
such shares of 1999 Preferred Stock to the Company free of any adverse interest.
No interest shall accrue on any payment upon Liquidation after the due date
thereof.

         5.       REDEMPTION.

                  (a)      OPTIONAL REDEMPTION. The Company, at its option, may
redeem the shares of 1999 Preferred Stock, in whole or in part, out of funds
legally available therefor, at any time or from time to time, subject to the
notice provisions and provisions for partial redemption described below at the
redemption price of $10,000 per share plus an amount equal to accrued and unpaid
dividends, if any, to (but excluding) the date fixed for redemption, whether or
not earned or declared in cash or by delivering fully paid and nonassessable
shares of Common Stock, and Non-Voting Common Stock, if any, on the terms and
conditions in this Section 5 and Section 8, or any combination thereof at the
sole option of the Company; PROVIDED that, if the applicable redemption date is
a Dividend Payment Date, the quarterly payment of dividends becoming due on such
date shall be payable to the holders of such shares of 1999 Preferred Stock
registered as such on the relevant record date subject to the terms and
provisions of Section 3.

                  If fewer than all the outstanding shares of the 1999 Preferred
Stock are to be redeemed, shares to be redeemed shall be selected by the Company
from outstanding shares of 1999 Preferred Stock not previously called for
redemption by lot or pro rata (as near as may be) or by any other equitable
method determined by the Company in its sole discretion. If fewer than all the
shares of 1999 Preferred Stock represented by any certificate are redeemed, a
new certificate shall be issued representing the unredeemed shares without cost
to the holder thereof. If a part of a share of 1999 Preferred Stock is redeemed,
then the Company will issue a certificate representing a fractional share of
1999 Preferred Stock evidencing the remaining interest of such holder.

                  (b)      MANDATORY REDEMPTION. On January 1, 2009, the Company
will redeem all of the outstanding shares of the 1999 Preferred Stock, out of
funds legally available therefor, at the redemption price of $10,000 per share
plus an amount equal to accrued and unpaid dividends, if any, to (but excluding)
the date fixed for redemption, whether or not





                                        6


<PAGE>   7
earned or declared, in cash or by delivering shares of Common Stock, and
Non-Voting Common Stock, if any, on the terms and conditions in this Section 5
and Section 8, or any combination thereof at the sole option of the Company.

                  (c)      No sinking fund or other similar provision shall
apply to the 1999 Preferred Stock.

                  (d)      In case the Company shall desire to exercise the
right to redeem the shares of 1999 Preferred Stock, in whole or in part,
pursuant to Section 5(a), it shall fix a date for redemption. In the case of any
redemption, the Company will notify, at least two (2) Business Days prior the
date fixed for redemption, the Transfer Agent and the holders of 1999 Preferred
Stock so to be redeemed at their last addresses and facsimile numbers as the
same appear on the Company's stock records. Such mailing shall be by facsimile
and by overnight courier. The notice if delivered in the manner herein provided
shall be conclusively presumed to have been duly given, whether or not the
holder receives such notice. In any case, failure to give such notice by courier
or any defect in the notice to the holder of any share of 1999 Preferred Stock
designated for redemption shall not affect the validity of the proceedings for
the redemption of any other share of 1999 Preferred Stock.

                  Each such notice of redemption shall specify the number of
shares of 1999 Preferred Stock to be redeemed, the date fixed for redemption,
the redemption price at which such shares of 1999 Preferred Stock are to be
redeemed, the place or places of payment, that payment will be made upon
presentation and surrender of certificate or certificates representing such
shares of 1999 Preferred Stock and in what form consideration will be paid, that
dividends accrued to (but excluding) the date fixed for redemption will be paid
as specified in said notice, and that on and after said date dividends thereon
or on the portion thereof to be redeemed will cease to accrue. If payment of the
redemption price shall be in shares of Common Stock, and Non-Voting Common
Stock, if any, such notice shall also state the Conversion Price applicable to
the redemption and the date on which the right to convert such shares of 1999
Preferred Stock into Common Stock, and Non-Voting Common Stock, if any, will
expire.

                  (e)      REDEMPTION IN CASH. If payment will be made in cash,
the following terms shall apply:

                  On or prior to the redemption date specified in the notice of
redemption given as provided in Section 5(d), the Company will deposit with the
Transfer Agent, or a bank or trust company acting as escrow agent for the
Company an amount of money sufficient to redeem on the redemption date all of
the shares of 1999 Preferred Stock so called for redemption at the appropriate
redemption price, together with accrued dividends (whether or not declared) to
(but excluding) the date fixed for redemption. The Company shall be entitled to
make any deposit of funds contemplated by this Section 5 under arrangements
designed to permit such funds to generate interest or other income for the
Company, and the Company




                                        7


<PAGE>   8
shall be entitled to receive all interest and other income earned by any funds
while they shall be deposited as contemplated by this Section 5.

                  (f)      REDEMPTION IN COMMON STOCK. If payment will be made
in shares of Common Stock, and Non-Voting Common Stock, if any, the following
terms shall apply:

                  On the redemption date specified in the notice of redemption
given as provided in Section 5(b), the Company will deliver to holders of 1999
Preferred Stock either (x) a certificate for Common Stock, and Non-Voting Common
Stock, if any, registered in the name(s) of each holder of 1999 Preferred Stock
or (y) a confirmation issued by the Transfer Agent to the effect that Common
Stock, and Non-Voting Common Stock, if any, in uncertificated form has been
registered in the name(s) of each holder of 1999 Preferred Stock on the books of
the Company, in either case evidencing or confirming the registration of that
full number of shares which, when multiplied by the Conversion Price, shall
equal the sum of the redemption price, together with accrued dividends (whether
or not declared) to (but excluding) the date fixed for redemption. No fractional
shares of Common Stock or NonVoting Common Stock shall be issued by the Company.
If any fractional share of Common Stock or Non-Voting Common Stock otherwise
would be issuable upon the redemption of the 1999 Preferred Stock, the Company
shall make an adjustment therefor in an amount of cash (without interest)
determined by multiplying such fraction by the Conversion Price of one share of
Common Stock.

                  (g)      TERMS APPLICABLE TO REDEMPTION IN CASH OR COMMON
STOCK. If notice of redemption has been given as above provided, on and after
the date fixed for redemption (unless the Company shall default in the payment
of the redemption price, together with accrued and unpaid dividends to (but
excluding) said date), dividends on such shares of 1999 Preferred Stock so
called for redemption shall cease to accrue and such shares of 1999 Preferred
Stock shall be deemed no longer outstanding and the holders thereof shall have
no right in respect of such shares of 1999 Preferred Stock except the right to
receive the redemption price thereof and accrued and unpaid dividends (whether
or not declared) to (but excluding) the date fixed for redemption, without
interest thereon. On presentation and surrender of certificate or certificates
representing such shares of 1999 Preferred Stock to the Transfer Agent or escrow
agent, which shall be specified in the notice to holders, such shares of 1999
Preferred Stock to be redeemed shall be redeemed by the Company at the
applicable redemption price, together with dividends accrued thereon (whether or
not declared) to (but excluding) the date fixed for redemption; PROVIDED that,
if the applicable redemption date is a Dividend Payment Date, the quarterly
payment of dividends becoming due on such date shall be payable to the holders
of such shares of 1999 Preferred Stock registered as such on the relevant record
date subject to the terms and provisions of Section 3.

         6.       SHARES TO BE RETIRED. Any share of 1999 Preferred Stock
converted, redeemed or otherwise acquired by the Company shall be retired and
canceled and shall upon cancellation be restored to the status of authorized but
unissued shares of 1999 Preferred


                                        8


<PAGE>   9
Stock, subject to reissuance by the Board of Directors as shares of 1999
Preferred Stock of one or more series.

         7.       CONVERSION. Holders of shares of 1999 Preferred Stock shall
have the right to convert all or a portion of such shares into shares of Common
Stock, and Non-Voting Common Stock, if any, as follows:

                  (a)      Subject to and upon compliance with the provisions of
this Section 7 and Section 8, a holder of shares of 1999 Preferred Stock shall
have the right, at his option, after September 1, 1999 and during any period
that the Closing Price of Common Stock on The Nasdaq National Market or a
national securities exchange registered as such pursuant to the Exchange Act and
on which the Common Stock is listed is above $45 per share for at least 10
consecutive Trading Days (except that, with respect to shares of 1999 Preferred
Stock which shall be called for redemption, such right shall terminate at the
close of business on the next succeeding Business Day after the date notice is
sent to the holders, unless the Company shall default in payment due upon
redemption thereof) to convert any share of 1999 Preferred Stock into that
number of fully paid and nonassessable shares of Common Stock, and Non-Voting
Common Stock, if any, (as such shares shall then be constituted) obtained by
dividing $10,000 plus any accrued dividends (whether or not declared) to (but
excluding) the date fixed for conversion by the Conversion Price, by surrender
of certificate or certificates representing such share of 1999 Preferred Stock
so to be converted in the manner provided in Section 7(b); PROVIDED that, in the
event that a third party, who is not an affiliate of the Company, acquires
greater than 49% of the voting stock of the Company and the holder could
otherwise convert his shares of 1999 Preferred Stock, the holder may convent
such shares of 1999 Preferred Stock prior to September 1, 1999. If a part of a
share of 1999 Preferred Stock is converted, then the Company shall convert such
share into the appropriate number of shares of Common Stock, and Non-Voting
Common Stock, if any, and issue a certificate representing a fractional share of
1999 Preferred Stock evidencing the remaining interest of such holder. A holder
of 1999 Preferred Stock is not entitled to any rights of a holder of Common
Stock or Non-Voting Common Stock until such holder has converted his 1999
Preferred Stock to Common Stock or Non-Voting Common Stock and only to the
extent such 1999 Preferred Stock is deemed to have been converted to Common
Stock or Non-Voting Common Stock under this Section 7.

                  (b)      In order to exercise the conversion right, the holder
of 1999 Preferred Stock who intends to convert shall send a written notice (the
"Conversion Notice"), at least thirty (30) Business Days prior to an intended
conversion, to the Company and the Transfer Agent of his, her or its election to
convert such number of shares of 1999 Preferred Stock specified in said notice.
The holder of the 1999 Preferred Stock to be converted shall surrender
certificate or certificates (with the Conversion Notice, the form of which is
set forth in Section 15(a), on the reverse of the certificate or certificates
duly completed) representing the number of shares to be so converted, duly
endorsed, to the Transfer Agent. The Conversion Notice shall also state the name
or names (with address) in which the certificate or certificates for shares of
Common Stock, and Non-Voting Common Stock, if any, issuable on



                                       9
<PAGE>   10

such conversion shall be issued, and shall be accompanied by transfer taxes, if
required pursuant to Section 8(b). Each such share of 1999 Preferred Stock
surrendered for conversion shall, unless the shares of Common Stock, and
Non-Voting Common Stock, if any, issuable on conversion are to be issued in the
same name in which such share of 1999 Preferred Stock is registered, be duly
endorsed by, or be accompanied by instruments of transfer in form satisfactory
to the Company duly executed by, the holder or his duly authorized attorney.

                  As promptly as practicable after satisfaction of the
requirements for conversion set forth above, the Company shall issue and shall
deliver to such holder or, if shares of Common Stock, and Non-Voting Common
Stock, if any, issuable on conversion are to be issued in a name other than that
in which such share of 1999 Preferred Stock to be converted is registered (as if
such transfer were a transfer of the share of 1999 Preferred Stock so
converted), to such other person, at the Transfer Agent, certificate or
certificates representing the number of shares of Common Stock, and Non-Voting
Common Stock, if any, issuable upon the conversion of such share of 1999
Preferred Stock or a portion thereof in accordance with the provisions of this
Section 7 and a check or cash in respect of any fractional interest in respect
of a share of Common Stock or Non-Voting Common Stock, if any, arising upon such
conversion, as provided in Section 7(c) (which payment, if any, shall be paid no
later than five Business Days after satisfaction of the requirements for
conversion set forth above).

                  Each conversion shall be deemed to have been effected on the
date on which the requirements set forth above in the first paragraph of this
Section 7(b) have been satisfied as to such share of 1999 Preferred Stock so
converted, and the person in whose name any certificate or certificates for the
shares of Common Stock, and Non-Voting Common Stock, if any, shall be issuable
upon such conversion shall be deemed to have become on said date the holder of
record of the shares represented thereby; PROVIDED, HOWEVER, that if any such
surrender occurs on any date when the stock transfer books of the Company shall
be closed, the conversion shall be effected on the next succeeding day on which
such stock transfer books are open, and the person in whose name the
certificates are to be issued shall be the record holder thereof for all
purposes, but such conversion shall be at the Conversion Price.

                  In the case of any share of 1999 Preferred Stock which is
converted after any Dividend Payment Record Date with respect to the payment of
a dividend on the 1999 Preferred Stock and prior to the close of business on the
Business Day prior to the next succeeding Dividend Payment Date, the dividend
due on such Dividend Payment Date shall be payable on such Dividend Payment Date
to the holder of record of such share as of such Dividend Payment Record Date
notwithstanding such conversion. Except as provided in this paragraph, no
payment or adjustment shall be made upon any conversion on account of any
dividends accrued on shares of 1999 Preferred Stock surrendered for conversion
or on account of any dividends on the Common Stock or Non-Voting Common Stock
issued upon conversion.




                                       10


<PAGE>   11
                  (c)      In connection with the conversion of any shares of
1999 Preferred Stock, a portion of such shares may be converted; however no
fractional shares of Common Stock or Non-Voting Common Stock or scrip
representing fractional shares shall be issued upon conversion of the 1999
Preferred Stock. If any fractional share of stock otherwise would be issuable
upon the conversion of the 1999 Preferred Stock, the Company shall make an
adjustment therefor in an amount of cash (without interest) determined by
multiplying such fraction by the Conversion Price of one share of Common Stock.
If more than one share shall be surrendered for conversion at one time by the
same holder, the number of full shares of Common Stock, and Non-Voting Common
Stock, if any, issuable upon conversion thereof shall be computed on the basis
of the aggregate number of shares of 1999 Preferred Stock so surrendered.

                  (d)      Upon receipt of a holder's notice of its intention to
convert (as provided in Section 7(b)), the Company shall have the option, in its
sole discretion, of redeeming the 1999 Preferred Stock to be converted into
Common Stock, and Non-Voting Common Stock, if any, for cash prior to such
conversion.

         8.       TERMS OF ISSUANCE OF COMMON STOCK, AND NON-VOTING COMMON
STOCK, IF ANY, ON REDEMPTION OR CONVERSION.

                  (a)      SHARE ISSUANCE LIMITATION. In no event shall the
Company issue or be required to issue, for redemption for stock or on
conversion, greater than 4,976,220 shares of Common Stock, and Non-Voting Common
Stock, if any, unless the Company has obtained the prior approval of a majority
of the holders of Common Stock (excluding any shares issued to holders of 1999
Preferred Stock hereunder), which approval the Company may seek in its sole
discretion at any time.

                  (b)      LIMITATION ON COMMON STOCK ISSUANCE; ISSUANCE OF
NON-VOTING COMMON STOCK. In the event of a redemption for stock or conversion,
whether in whole or in part, the Company shall issue only that number of shares
of Common Stock so that the holder of 1999 Preferred Stock shall beneficially
own, together with any other shares of the Company's stock entitled to vote for
the election of directors ("Voting Stock"), (a) no more than 49.99% of the
issued and outstanding shares of Voting Stock and (b) an amount of Voting Stock,
the aggregate value (as defined in the Hart-Scott-Rodino Antitrust Improvement
Act (16 C.F.R. Section 801.10)) of which, is no greater than $15 million. In the
event that the number of shares of Common Stock issued in accordance with the
foregoing limitation do not equal the full amount of shares of Common Stock
otherwise issuable to such holder upon such conversion or redemption, then the
Company shall issue that number of shares of Non-Voting Common Stock which makes
up the difference between the number of shares of Common Stock actually issued
and the number of shares issuable.

                  (c)      The issue of stock certificates representing the
shares of Common Stock, and Non-Voting Common Stock, if any, on conversions or
redemption of the 1999 Preferred




                                       11


<PAGE>   12

Stock shall be made without charge to the relevant holder of 1999 Preferred
Stock for any tax in respect of the issue thereof. The Company shall not,
however, be required to pay any tax which may be payable in respect of any
transfer involved in the issue and delivery of stock in any name other than the
name in which the shares of 1999 Preferred Stock with respect to which such
shares of Common Stock, and Non-Voting Common Stock, if any, are issued are
registered, and the Company shall not be required to issue or deliver any such
stock certificate unless and until the person or persons requesting the issue
thereof shall have paid to the Company the amount of such tax or shall have
established to the satisfaction of the Company that such tax has been paid.

                  (d)      The Company covenants that all shares of Common Stock
and NonVoting Common Stock which may be delivered upon conversion or redemption
of shares of 1999 Preferred Stock will upon delivery be duly and validly issued
and fully paid and non-assessable, free of all liens and charges and not subject
to any preemptive rights.

                  (e)      The Company covenants that it will at all times
reserve and keep available, free from preemptive rights, out of the aggregate of
its authorized but unissued shares of Common Stock and Non-Voting Common Stock
or its issued shares of Common Stock held in its treasury, or both, a sufficient
number of shares of Common Stock and NonVoting Common Stock for the purpose of
effecting conversions of shares of 1999 Preferred Stock not theretofore
converted into Common Stock or Non-Voting Common Stock. For purposes of this
reservation of Common Stock and Non-Voting Common Stock, the number of shares of
Common Stock and Non-Voting Common Stock which shall be deliverable upon the
conversion of all outstanding shares of 1999 Preferred Stock shall be computed
as if at the time of computation all outstanding shares of 1999 Preferred Stock
were held by a single holder. The issuance of shares of Common Stock, and
Non-Voting Common Stock, if any, upon conversion or redemption of shares of 1999
Preferred Stock is authorized in all respects. The Company shall from time to
time, in accordance with the laws of the Commonwealth of Pennsylvania, use its
best efforts to increase the authorized number of shares of Common Stock or
Non-Voting Common Stock if at any time the number of shares of authorized and
unissued Common Stock or Non-Voting Common Stock shall not be sufficient to
permit the conversion or redemption of all the then outstanding shares of 1999
Preferred Stock.

                  (f)      The Company further covenants that if at any time the
Common Stock shall be listed on The Nasdaq National Market or any other national
securities exchange or automated quotation system the Company will, if permitted
by the rules of such exchange or automated quotation system, list and keep
listed, so long as the Common Stock shall be so listed on such exchange or
automated quotation system, all Common Stock issuable upon conversion or
redemption upon such conversion into or redemption for Common Stock.

         9.       RANKING.

                  (a)      the 1999 Preferred Stock ranks junior to the $3.25
Convertible Exchangeable Preferred Stock and prior to the Common Stock and the
Non-Voting Common Stock as to dividends (except as provided in Section 3(c)
hereof) or as to distribution of assets upon liquidation, dissolution or winding
up;

                  (b)      As to any future classes of capital stock of the
Company, as to dividends or as to the distribution of assets upon liquidation,
dissolution or winding up, the 1999 Preferred Stock will rank prior to, on
parity with or junior to, such capital stock if the Second Amended and Restated
Articles of Incorporation, as amended from time to time, provide that the
holders of such capital stock are entitled to receipt of dividends or of amounts
distributable upon liquidation, dissolution or winding up, as the case may be,
in preference to, on a parity with, or junior to the holders of shares of 1999
Preferred Stock.

         10.      VOTING RIGHTS.

                  (a)      The holders of 1999 Preferred Stock will not have any
voting rights except as set forth below or as otherwise from time to time
required by law. In connection with any right to vote, each holder of 1999
Preferred Stock will have one vote for each share of 1999 Preferred Stock held.
Any shares of 1999 Preferred Stock held by the Company or any entity controlled
by the Company shall not have voting rights hereunder and shall not be counted
in determining the presence of a quorum.

                  (b)      So long as the 1999 Preferred Stock is outstanding,
the Company shall not, without the affirmative vote or consent of the holders of
at least a majority (unless a higher percentage shall then be required by
applicable law) of all outstanding shares of 1999 Preferred Stock voting
separately as a class, amend, alter or repeal any provision of the Articles of
Incorporation (including, without limitation, these resolutions) or the Bylaws
of the Company so as to affect adversely the relative rights, preferences,
qualifications, limitations or restrictions of the 1999 Preferred Stock;
PROVIDED, HOWEVER, that no such vote shall be required to create, authorize or
issue, or reclassify any authorized stock of the Company into, or increase the
authorized amount of, any class or series of the Company's capital stock ranking
senior to, on parity with, or junior to the 1999 Preferred Stock as to dividends
or as to distributions of assets upon liquidation, dissolution or winding up of
the Company, whether voluntary or involuntary, or any obligation or security
convertible into shares of such a class or series. In addition, so long as the
1999 Preferred Stock is outstanding, the Company shall not, without the
affirmative vote or consent of the holders of at least a majority (unless a
higher percentage shall then be required by applicable law) of all outstanding
shares of 1999 Preferred Stock voting separately as a class, enter into a share
exchange pursuant to which the 1999 Preferred Stock would be exchanged for any
other securities or merge or consolidate with or into any other person or permit
any other person to merge or consolidate with or into



                                       13


<PAGE>   14
the Company, unless in such case each share of 1999 Preferred Stock shall remain
outstanding or unaffected or shall be converted into or exchanged for redeemable
convertible exchangeable preferred stock of the surviving entity having voting
rights, preferences, limitations or special rights thereof substantially similar
(but no less favorable) to a share of 1999 Preferred Stock. A class vote on the
part of the 1999 Preferred Stock shall, without limitation, specifically not be
deemed to be required (except as otherwise required by law or resolution of the
Company's Board of Directors) in connection with the authorization, issuance or
increase in the amount of any bonds, mortgages, debentures or other obligations
of the Company.

         11.      EXCHANGE.

                  (a)      The 1999 Preferred Stock shall be exchangeable, in
whole but not in part, at the option of the Company on any Dividend Payment Date
beginning June 1, 1999, for the Debentures at the rate of $10,000 principal
amount of Debentures for each share of 1999 Preferred Stock outstanding at the
time of exchange; PROVIDED that the Debentures will be issuable in denominations
of $10,000 and integral multiples thereof. If the exchange results in an amount
of Debentures that is not an integral multiple of $10,000, the amount in excess
of the closest integral multiple of $10,000 will be paid in cash by the Company.

                  (b)      The Company will mail to each record holder of 1999
Preferred Stock written notice of its intention to exchange the 1999 Preferred
Stock for the Debentures no less than 60 days prior to the proposed date of the
exchange (the "Proposed Exchange Date"). The notice shall include the proposed
form of indenture which shall have terms substantially similar to the terms of
the 1999 Preferred Stock with such other terms as are reasonable or customary in
indentures for corporate debt and shall specify the Proposed Exchange Date, the
place or places where certificates for shares of 1999 Preferred Stock are to be
surrendered for Debentures and shall state that dividends on the 1999 Preferred
Stock will cease to accrue on and after the actual date of the exchange (the
"Exchange Date"). Upon receipt of the notice and the form of indenture, the
holders shall promptly and in good faith review and negotiate the indenture with
the understanding that time is of the essence. While the Company, the holders
and proposed trustee are negotiating the indenture, the Company may set a new
Proposed Exchange Date by notifying the holders.

                  (c)      If (i) the holders have agreed to the terms of the
indenture, which shall not be unreasonably withheld, (ii) the Company and a
reputable trustee have properly authorized and executed the indenture and (iii)
the Company has caused the Debentures to be authenticated on or prior to the
Exchange Date and has complied with the other provisions of this Section 11,
then, notwithstanding that any certificates for shares of 1999 Preferred Stock
have not been surrendered for exchange, on the Exchange Date dividends shall
cease to accrue on the 1999 Preferred Stock and at the close of business on the
Exchange Date the holders of 1999 Preferred Stock shall cease to be shareholders
with respect to the 1999 Preferred Stock and shall have no interest in or other
claims against the Company by virtue thereof and shall have no voting or other
rights with respect to the 1999 Preferred Stock, except the right to



                                       14


<PAGE>   15
receive the Debentures issuable upon such exchange and the right to accumulated
and unpaid dividends as of the Exchange Date, without interest thereon, upon
surrender (and endorsement, if required by the Company) of their certificates,
and the shares evidenced thereby shall no longer be deemed outstanding for any
purpose. The Company will cause the Debentures to be authenticated on or before
the Exchange Date, and the Company will pay interest on the Debentures at the
rate and on the dates specified in such Indenture from and after the Exchange
Date.

                  (d)      Notwithstanding the foregoing, if notice of exchange
has been given pursuant to this Section 11 and any holder of shares of 1999
Preferred Stock shall, prior to the close of business on the Exchange Date, give
written notice to the Company pursuant to Section 7 of the conversion of any or
all of the shares held by the holder (accompanied by a certificate or
certificates for such shares, duly endorsed or assigned to the Company), then
the exchange shall not become effective as to the shares to be converted and the
conversion shall become effective as provided in Section 7.

                  (e)      The Debentures will be delivered to the persons
entitled thereto upon surrender to the Company or its agent appointed for that
purpose of the certificates for the shares of 1999 Preferred Stock being
exchanged therefor.

                  (f)      Notwithstanding the other provisions of this Section
11, if on the Exchange Date the Company has not paid full cumulative dividends
on the 1999 Preferred Stock (or set aside a sum therefor) or an Event of Default
under the Indenture shall have occurred and be continuing, the Company may not
exchange the 1999 Preferred Stock for the Debentures and any notice previously
given pursuant to this Section 11 shall be of no effect.

                  (g)      Prior to the Exchange Date, the Company will comply
with any applicable securities and blue sky laws with respect to the exchange of
the 1999 Preferred Stock for the Debentures.

                  (h)      Dividends with respect to the shares of 1999
Preferred Stock to be exchanged which are due on the quarterly Dividend Payment
Date on which the exchange is effected will be mailed to holders in the regular
course.

         12.      RECORD HOLDERS. The Company and the Transfer Agent may deem
and treat the record holder of any shares of 1999 Preferred Stock as the true
and lawful owner thereof for all purposes and neither the Company nor the
Transfer Agent shall be affected by any notice to the contrary.

         13.      NOTICE. Except as may otherwise be provided for herein, all
notices referred to herein shall be in writing, and all notices hereunder shall
be deemed to have been given upon the earlier of receipt of such notice or three
Business Days after the mailing of such notice if sent by registered mail
(unless first-class mail shall be specifically permitted for such notice




                                       15

Company, to its offices at 64 Sidney Street, Cambridge, Massachusetts 02139-4136
(Attention: Chief Financial Officer) or to an agent of the Company designated as

such holder at the address of such holder of 1999 Preferred Stock as listed in
the Company's stock records or to such other address as the Company or holder,
as the case may be, shall have designated by notice similarly given.

         14.      RESTRICTIONS ON TRANSFER.

                  (a)      RESTRICTED SECURITIES. The shares of 1999 Preferred
Stock have not been registered under the Securities Act and therefore are
"restricted securities" under the federal securities laws. Under such laws and
applicable regulations, such shares may be resold without registration under the
Securities Act only in certain limited circumstances pursuant to the resale
limitations imposed thereby.

                  (b)      LIMITATIONS ON DISPOSITIONS. Under the Securities
Act, dispositions of all or any portion of the shares of 1999 Preferred Stock
cannot be made unless and until:

                           (i)      There is then in effect a registration
statement under the Securities Act covering such proposed disposition and such
disposition is made in accordance with such registration statement; or

                           (ii)     There exists an exemption under the
Securities Act so that such disposition will not require registration of such
shares under the Securities Act, including a disposition made in accordance with
Rule 144.

                  (d)      LEGEND. Certificates evidencing the shares of 1999
Preferred Stock may bear the following legend: "The Securities evidenced by this
certificate have not been registered under the Securities Act of 1933, as
amended (the "Act"), and are "restricted securities" as defined in Rule 144
promulgated under the Act. The securities may not be sold or offered for sale or
otherwise distributed except (i) pursuant to an effective registration statement
for the securities under the Act; (ii) in compliance with Rule 144; or (iii)
after receipt of an opinion of counsel reasonably satisfactory to Alkermes that
such registration or compliance is not required as to said sale, offer or
distribution."

                                 ALKERMES, INC.

                  EXHIBIT A TO STATEMENT WITH RESPECT TO SHARES

                RESOLUTIONS ESTABLISHING NON-VOTING COMMON STOCK
                                ($.01 Par Value)

                                   ----------

         RESOLVED, that pursuant to authority expressly granted to and vested in
the Board of Directors of Alkermes, Inc. (the "Company"), a Pennsylvania
corporation, by the provisions of the Second Amended and Restated Articles of
Incorporation, as amended, of the Company (the "Articles of Incorporation"),
there is hereby established a series of common stock, par value $.01 per share,
which shall consist of 450,000 of the 2,000,000 shares of the undesignated and
unissued capital stock of the Company, and which shall have the following
designation and voting rights, limitations and special rights:

         1.       NUMBER OF SHARES AND DESIGNATION. 450,000 shares of capital
stock, par value $.01 per share, of the Company are hereby constituted as a
series of the common stock designated as Non-Voting Common Stock (the
"Non-Voting Common Stock").

         2.       VOTING RIGHTS.

                  (a)      The holders of Non-Voting Common Stock will not have
any voting rights except as set forth below or as otherwise from time to time
required by law. In connection with any right to vote, each holder of Non-Voting
Common Stock will have one vote for each share of Non-Voting Common Stock held.
Any shares of Non-Voting Common Stock held by the Company or any entity
controlled by the Company shall not have voting rights hereunder and shall not
be counted in determining the presence of a quorum.

                  (b)      So long as the Non-Voting Common Stock is
outstanding, the Company shall not, without the affirmative vote or consent of
the holders of at least a majority (unless a higher percentage shall then be
required by applicable law) of all outstanding shares of Non-Voting Common Stock
voting separately as a class, amend, alter or repeal any provision of the
Articles of Incorporation (including, without limitation, these resolutions) or
the Bylaws of the Company so as to affect adversely the rights of the Non-Voting
Common Stock; PROVIDED, HOWEVER, that no such vote shall be required to create,
authorize or issue, or reclassify any authorized stock of the Company into, or
increase the authorized amount of, any class or series of the Company's capital
stock ranking senior to, or on parity with, the Non-Voting Common Stock as to
dividends or as to distributions of assets upon liquidation, dissolution or
winding up of the Company, whether voluntary or involuntary, or any obligation
or security convertible into shares of such a class or series.

         3.       DIVIDEND, LIQUIDATION AND OTHER RIGHTS; SUBDIVISION AND
COMBINATIONS. The holders of shares of Non-Voting Common Stock (a) shall be
entitled to receive the same





<PAGE>   2
dividends or distributions, in cash, shares of stock or other property, as the
holders of Common Stock receive; (b) shall be entitled to the same liquidation
rights as, and on a parity with, the holders of Common Stock; and (c) shall be
entitled to any other rights or privileges as, and on a parity with, the holders
of the Common Stock. If the outstanding shares of Common Stock shall be
subdivided into a greater number of shares of Common Stock, or shall be combined
into a smaller number of shares of Common Stock, the shares of Non-Voting Common
Stock shall be similarly subdivided or combined.

         4.       AUTOMATIC CONVERSION. Each share of Non-Voting Common Stock
shall automatically be converted into one share of Common Stock immediately upon
the transfer of ownership by the initial holder or an "affiliate" of the initial
holder to a third party which is not an "affiliate" of such holder. In the event
of such an automatic conversion, the outstanding shares of Non-Voting Common
Stock shall be converted automatically without any further action by the holder
of such shares and whether or not the certificates representing such shares are
surrendered to the Company or its transfer agent. The Company shall not be
obligated to issue certificates evidencing the shares of Common Stock issuable
upon such automatic conversion unless the certificates evidencing such shares of
Non-Voting Common Stock are delivered to the Company or its transfer agent. Such
conversion shall be deemed to have been made on the date of transfer to such
third party holder and the person(s) entitled to receive shares of Common Stock
issuable upon conversion shall be treated for all purposes as the record holder
or holders of such shares of Common Stock as of such date. For purposes of this
section 4, "affiliate" means a person or an entity that directly or indirectly
controls, is controlled by or is under common control with the holder, where
"control" means the direct or indirect ownership of fifty percent or more of the
stock having the right to vote for directors thereof or the ability to otherwise
control the management of the holder.

         5.       CONVERSION AT HOLDER'S OPTION. (a) Subject to the limitation
in Section 5(c) below, each share of Non-Voting Common Stock shall be
convertible, at the option of the holder of such share, into one share of Common
Stock, by surrender of certificate or certificates representing the share or
shares of Non-Voting Common Stock to be converted in the manner provided in
Section 5(b). A holder of Non-Voting Common Stock is not entitled to any rights
of a holder of Common Stock until such holder has converted his Non-Voting
Common Stock to Common Stock and only to the extent such Non-Voting Common Stock
is deemed to have been converted to Common Stock under this Section 5.

                  (b)      In order to exercise the conversion right, the holder
of Non-Voting Common Stock who intends to convert shall send a written notice
(the "Conversion Notice"), at least thirty (30) business days prior to an
intended conversion, to the Company and the Transfer Agent of his, her or its
election to convert such number of shares of Non-Voting Common Stock specified
in said notice. The holder of the Non-Voting Common Stock to be converted shall
surrender certificate or certificates (with the Conversion Notice) representing
the number of shares to be so converted, duly endorsed, to the Transfer Agent.
The Conversion Notice shall also state the name or names (with address) in which
the certificate or certificates for shares of Common Stock issuable on such
conversion shall be issued, and shall be accompanied by





<PAGE>   3
transfer taxes, if required. Each such share of Non-Voting Common Stock
surrendered for conversion shall, unless the shares of Common Stock issuable on
conversion are to be issued in the same name in which such share of Non-Voting
Common Stock is registered, be duly endorsed by, or be accompanied by
instruments of transfer in form satisfactory to the Company duly executed by,
the holder or his duly authorized attorney.

                  As promptly as practicable after satisfaction of the
requirements for conversion set forth above, the Company shall issue and shall
deliver to such holder or, if shares of Common Stock issuable on conversion are
to be issued in a name other than that in which such share of Non-Voting Common
Stock to be converted is registered (as if such transfer were a transfer of the
share of Non-Voting Common Stock so converted), to such other person, at the
Transfer Agent, certificate or certificates representing the number of shares of
Common Stock issuable upon the conversion of such share of Non-Voting Common
Stock in accordance with the provisions of this Section 5.

                  Each conversion shall be deemed to have been effected on the
date on which the requirements set forth above in the first paragraph of this
Section 5(b) have been satisfied as to such share of Non-Voting Common Stock so
converted, and the person in whose name any certificate or certificates for the
shares of Common Stock shall be issuable upon such conversion shall be deemed to
have become on said date the holder of record of the shares represented thereby;
PROVIDED, HOWEVER, that if any such surrender occurs on any date when the stock
transfer books of the Company shall be closed, the conversion shall be effected
on the next succeeding day on which such stock transfer books are open, and the
person in whose name the certificates are to be issued shall be the record
holder thereof for all purposes.

                  (c)      Any holder of Non-Voting Common Stock may only
convert into Common Stock that number of shares of Non-Voting Common Stock so
that such converting holder of Non-Voting Common Stock shall beneficially own,
together with any other shares of the Company's stock entitled to vote for the
election of directors ("Voting Stock"), (a) no more than 49.99% of the issued
and outstanding shares of Voting Stock and (b) an amount of Voting Stock, the
aggregate value (as defined in the Hart-Scott-Rodino Antitrust Improvement Act
(16 C.F.R. Section 801.10)) of which, is no greater than $15 million.

            INDEMNIFICATION OF DIRECTORS, OFFICERS, AND OTHER PERSONS
            ---------------------------------------------------------

         5.1      INDEMNIFICATION OF DIRECTORS, OFFICERS, AND OTHER PERSONS. The
Corporation shall indemnify any director, officer, employee or agent of the
Corporation or any of its subsidiaries who was or is an "authorized
representative" of the Corporation (which shall mean, for the purpose of this
Article, a director or officer of the Corporation, or a person serving at the
request of the Corporation as a director, officer, partner, fiduciary or trustee
of another corporation, partnership, joint venture, trust, employee benefit plan
or other enterprise) and who was or is a "party" (which shall include for
purposes of this Article the giving of testimony or similar involvement) or is
threatened to be made a party to any "proceeding" (which shall mean for purposes
of this Article any threatened, pending or completed action, suit, appeal or
other proceeding of any nature, whether civil, criminal, administrative or
investigative, whether formal or informal, and whether brought by or in the
right of the Corporation, its shareholders or otherwise) by reason of the fact
that such person was or is an authorized representative of the




                                       12


<PAGE>   13
Corporation to the fullest extent permitted by law, including without limitation
indemnification against expenses (which shall include for purposes of this
Article attorneys' fees and disbursements), damages, punitive damages,
judgments, penalties, fines and amounts paid in settlement actually and
reasonably incurred by such person in connection with such proceeding unless the
act or failure to act giving rise to the claim is finally determined by a court
to have constituted willful misconduct or recklessness. If an authorized
representative is not entitled to indemnification in respect of a portion of any
liabilities to which such person may be subject, the Corporation shall
nonetheless indemnify such person to the maximum extent for the remaining
portion of the liabilities.

         5.2      ADVANCEMENT OF EXPENSES. The Corporation shall pay the
expenses (including attorneys' fees and disbursements) actually and reasonably
incurred in defending a proceeding on behalf of any person entitled to
indemnification under Section 5.1 in advance of the final disposition of such
proceeding upon receipt of an undertaking by or on behalf of such person to
repay such amount if it shall ultimately be determined that such person is not
entitled to be indemnified by the Corporation as authorized in this Article and
may pay such expenses in advance on behalf of any employee or agent on receipt
of a similar undertaking. The financial ability of such authorized
representative to make such repayment shall not be prerequisite to the making of
an advance.



                                       13

<PAGE>   14

         5.3      EMPLOYEE BENEFIT PLANS. For purposes of this Article, the
Corporation shall be deemed to have requested an officer, director, employee or
agent to serve as fiduciary with respect to an employee benefit plan where the
performance by such person of duties to the Corporation also imposes duties on,
or otherwise involves services by, such person as a fiduciary with respect to
the plan; excise taxes assessed on an authorized representative with respect to
any transaction with an employee benefit plan shall be deemed "fines"; and
action taken or omitted by such person with respect to an employee benefit plan
in the performance of duties for a purpose reasonably believed to be in the
interest of the participants and beneficiaries of the plan shall be deemed to be
for a purpose which is not opposed to the best interests of the Corporation.

         5.4      SECURITY FOR INDEMNIFICATION OBLIGATIONS. To further effect,
satisfy or secure the indemnification obligations provided herein or otherwise,
the Corporation may maintain insurance, obtain a letter of credit, act as
self-insurer, create a reserve, trust, escrow, cash collateral or other fund or
account, enter into indemnification agreements, pledge or grant a security
interest in any assets or properties of the Corporation, or use any other
mechanism or arrangement whatsoever in such amounts, at such costs, and upon
such other terms and conditions as the Board of Directors shall deem
appropriate.

         5.5      RELIANCE UPON PROVISIONS. Each person who shall act as an
authorized representative of the Corporation shall be



                                       14


<PAGE>   15
deemed to be doing so in reliance upon the rights of indemnification provided by
this Article.

         5.6      AMENDMENT OR REPEAL. All rights of indemnification under this
Article shall be deemed a contract between the Corporation and the person
entitled to indemnification under this Article pursuant to which the Corporation
and each such person intend to be legally bound. Any repeal, amendment or
modification hereof shall be prospective only and shall not limit, but may
expand, any rights or obligations in respect of any proceeding whether commenced
prior to or after such change to the extent such proceeding pertains to actions
or failures to act occurring prior to such change.

         5.7      SCOPE OF ARTICLE. The indemnification, as authorized by this
Article, shall not be deemed exclusive of any other rights to which those
seeking indemnification or advancement of expenses may be entitled under any
statute, agreement, vote of shareholders or disinterested directors or
otherwise, both as to action in an official capacity and as to action in any
other capacity while holding such office. The indemnification and advancement of
expenses provided by, or granted pursuant to, this Article shall continue as to
a person who has ceased to be an officer, director, employee or agent in respect
of matters arising prior to such time, and shall inure to the benefit of the
heirs, executors and administrators of such person.

to time in its discretion, and will, so long as it is obligated under any
agreement or contract with its shareholders, cause the Company to send financial
statements to the shareholders. Such financial statements may be consolidated

may determine in its discretion. Except as otherwise provided by agreement with
its shareholders, such financial statements shall not be required to be prepared
on the basis of generally accepted accounting principles, shall not be required
to be audited or reviewed and shall not be required to be accompanied by either
a report of a public accountant engaged to audit or review such financial
statements or a statement of the person in charge of the financial records of
the Company.

printed. Where the certificates are signed by a transfer agent or a registrar,
the signature of any officer of the Corporation appearing thereon may be a
facsimile, engraved or printed. The fact that an officer whose signature, manual
or in facsimile, appears on any certificate shall cease to be an officer of the
Corporation, either before or after such certificate is issued, shall not
invalidate such certificate.

         7.2      LOSS OR DESTRUCTION OF CERTIFICATES. In case of loss or
destruction of a certificate, no new certificate shall be issued in lieu thereof
except upon satisfactory proof to the Board of Directors of such loss or
destruction and, in the discretion of the Board of Directors, upon the posting
of a bond or other indemnity in an amount satisfactory to the Board.

by-laws may be effectively waived by the person entitled thereto by written

                                                                    Exhibit 10.6


This Plan was initially approved on April 3, 1998 and, as assumed by the
Company, was approved by its Board of Directors on April 7, 1999.



                                 ALKERMES, INC.
                           1998 EQUITY INCENTIVE PLAN

1.       Purpose

         The purpose of the Alkermes, Inc. 1998 Equity Incentive Plan (the
"PLAN") is to attract and retain key employees and consultants of the Company
and its Affiliates, to provide an incentive for them to achieve long-range
performance goals, and to enable them to participate in the long-term growth of
the Company by granting Awards with respect to the Company's Common Stock.
Certain capitalized terms used herein are defined in Section 8 below.


2.       Administration

         The Plan shall be administered by the Committee. The Committee shall
select the Participants to receive Awards and shall determine the terms and
conditions of the Awards. The Committee shall have authority to adopt, alter and
repeal such administrative rules, guidelines and practices governing the
operation of the Plan as it shall from time to time consider advisable, and to
interpret the provisions of the Plan. The Committee's decisions shall be final
and binding. To the extent permitted by applicable law, the Committee may
delegate to one or more executive officers of the Company the power to make
Awards to Participants who are not Covered Employees.

3.       Eligibility

         All employees and consultants of the Company or any Affiliate capable
of contributing significantly to the successful performance of the Company,
other than a person who has irrevocably elected not to be eligible, are eligible
to be Participants in the Plan. Incentive Stock Options were granted only to
persons eligible to receive such Options under the Code.

4.       Stock Available for Awards

         (a)      Amount. Subject to adjustment under subsection (b), Awards may
be made under the Plan for up to 591,487 shares of Common Stock, of which shares
Options to purchase 119,474 shares of Common Stock and 53,327 shares of
Restricted Stock were awarded prior to the assumption of the Plan, leaving
418,686 shares of Common Stock available for Awards. If any Award expires or is
terminated unexercised or is forfeited or settled in a manner that results in
fewer shares outstanding than were awarded, the shares subject to such Award, to
the extent of such expiration, termination, forfeiture or decrease, shall again
be available for award under the Plan. Common Stock issued through the
assumption or substitution of outstanding grants from an acquired company shall
not reduce the shares available for Awards under the Plan. Shares issued under
the Plan may consist in whole or in part of authorized but unissued shares or
treasury shares.






<PAGE>   2
         (b)      Adjustment. In the event that the Committee determines that
any stock dividend, extraordinary cash dividend, recapitalization,
reorganization, merger, consolidation, split-up, spin-off, combination, exchange
of shares or other transaction affects the Common Stock such that an adjustment
is required in order to preserve the benefits intended to be provided by the
Plan, then the Committee (subject in the case of Incentive Stock Options to any
limitation required under the Code) shall equitably adjust any or all of (i) the
number and kind of shares in respect of which Awards may be made under the Plan,
(ii) the number and kind of shares subject to outstanding Awards, (iii) the
exercise price with respect to any of the foregoing, provided that the number of
shares subject to any Award shall always be a whole number, and (iv) if
considered appropriate, the Committee may make provision for a cash payment with
respect to an outstanding Award; provided that in the case (i) or (ii) above the
number of shares subject to any Award shall always be a whole number.

5.       Stock Options

         (a)      Grant of Options. Subject to the provisions of the Plan, after
the assumption of the Plan by the Company the Committee may grant options
("OPTIONS") to purchase shares of Common Stock not intended to comply with the
requirements of Section 422 of the Code or any successor provision and any
regulations thereunder ("NONSTATUTORY STOCK OPTIONS"). The Committee shall
determine the number of shares subject to each Option and the exercise price
therefor. Prior to the date of the assumption of the Plan by the Company,
Options to purchase shares of Common Stock complying with the requirements of
Section 422 of the Code or any successor provision and any regulations
thereunder ("INCENTIVE STOCK OPTIONS") were granted as authorized under the Plan
and such granted Incentive Stock Options remain in full force and effect.
Incentive Stock Options had or shall have an exercise price of at least
100% of the Fair Market Value of the Common Stock on the date of grant. No
Incentive Stock Option may be granted hereunder after the effective date of the
assumption of the Plan by the Company.

         (b)      Terms and Conditions. Each Option shall be exercisable at such
times and subject to such terms and conditions as the Committee may specify in
the applicable grant or thereafter. The Committee may impose such conditions
with respect to the exercise of Options, including conditions relating to
applicable federal or state securities laws, as it considers necessary or
advisable.

         (c)      Payment. No shares shall be delivered pursuant to any exercise
of an Option until payment in full of the exercise price therefor is received by
the Company. Such payment for shares to be delivered pursuant to any exercise of
an Option may be made in whole or in part in cash or, to the extent permitted by
the Committee at or after the grant of the Option, by delivery of a note or
other commitment satisfactory to the Committee or shares of Common Stock owned
by the optionee, including Restricted Stock, or by retaining shares otherwise
issuable pursuant to the Option, in each case valued at their Fair Market Value
on the date of delivery or retention, or such other lawful consideration,
including a payment commitment of a financial or brokerage institution, as the
Committee may determine.

6.       Restricted Stock

         (a)      Grant of Restricted Stock. Subject to the provisions of the
Plan, the Committee may grant shares of Common Stock subject to forfeiture
("RESTRICTED STOCK") and determine the duration of the period (the "RESTRICTED
PERIOD") during which, and the conditions under which, the shares may be
forfeited to the Company and the other terms and conditions of such Awards.
Shares of Restricted Stock may be issued for no cash consideration, such minimum
consideration as may be required by applicable law or such other consideration
as the Committee may determine.



                                        2


<PAGE>   3
         (b)      Restrictions. Shares of Restricted Stock (may not be sold,
assigned, transferred, pledged or otherwise encumbered, except as permitted by
the Committee, during the Restricted Period. Shares of Restricted Stock shall be
evidenced in such manner as the Committee may determine. Any certificates issued
in respect of shares of Restricted Stock shall be registered in the name of the
Participant and unless otherwise determined by the Committee, deposited by the
Participant, together with a stock power endorsed in blank, with the Company. At
the expiration of the Restricted Period, the Company shall deliver such
certificates to the Participant or if the Participant has died, to the
Participant's Designated Beneficiary.

7.       General Provisions Applicable to Awards

         (a)      Documentation. Each Award under the Plan shall be evidenced by
a writing, delivered to the Participant specifying the terms and conditions
thereof and containing such other terms and conditions not inconsistent with the
provisions of the Plan as the Committee considers necessary or advisable to
achieve the purposes of the Plan or to comply with applicable tax and regulatory
laws and accounting principles.

         (b)      Committee Discretion. Each type of Award may be made alone, in
addition to or in relation to any other Award. The terms of each type of Award
need not be identical, and the Committee need not treat Participants uniformly.
Except as otherwise provided by the Plan or a particular Award, any
determination with respect to an Award may be made by the Committee at the time
of grant or at any time thereafter.

         (c)      Dividends and Cash Awards. In the discretion of the Committee,
any Award under the Plan may provide the Participant with (i) dividends or
dividend equivalents payable (in cash or in the form of Awards under the Plan)
currently or deferred with or without interest and (ii) cash payments in lieu of
or in addition to an Award.

         (d)      Termination of Employment. The Committee shall determine the
effect on an Award of the disability, death, retirement or other termination of
employment of a Participant and the extent to which, and the period during
which, the Participant's legal representative, guardian or Designated
Beneficiary may receive payment of an Award or exercise rights thereunder.

         (e)      Change in Control. In order to preserve a Participant's rights
under an Award in the event of a "CHANGE IN CONTROL" (as defined by the
Committee) of the Company, the Committee in its discretion may, at the time an
Award is made or at any time thereafter, take one or more of the following
actions: (i) provide for the acceleration of any time period relating to the
exercise or payment of the Award, (ii) provide for payment to the Participant of
cash or other property with a Fair Market Value equal to the amount that would
have been received upon the exercise or payment of the Award had the Award been
exercised or paid upon the change in control, (iii) adjust the terms of the
Award in a manner determined by the Committee to reflect the change in control,
(iv) cause the Award to be assumed, or new rights substituted therefor, by
another entity, or (v) make such other provision as the Committee may consider
equitable to Participants and in the best interests of the Company.

         (f)      Loans. The Committee may authorize the making of loans or
cash payments to Participants in connection with the grant or exercise of any
Award under the Plan, which loans may be secured by any security, including
Common Stock, underlying or related to such Award (provided that the loan shall
not exceed the Fair Market Value of the security subject to such Award), and
which may be forgiven upon such terms and conditions as the Committee may
establish at the time of such loan or at any time thereafter.




                                        3


<PAGE>   4
         (g)      Transferability. In the discretion of the Committee, any Award
may be made transferable upon such terms and conditions and to such extent as
the Committee determines, provided that Incentive Stock Options may be
transferable only to the extent permitted by the Code. The Committee may in its
discretion waive any restriction on transferability.

         (h)      Withholding Taxes. The Participant shall pay to the Company,
or make provision satisfactory to the Committee for payment of, any taxes
required by law to be withheld in respect of Awards under the Plan no later than
the date of the event creating the tax liability. The Company and its Affiliates
may, to the extent permitted by law, deduct any such tax obligations from any
payment of any kind otherwise due to the Participant. In the Committee's
discretion, such tax obligations may be paid in whole or in part in shares of
Common Stock, including shares retained from the Award creating the tax
obligation, valued at their Fair Market Value on the date of delivery. The
Company and its Affiliates may, to the extent permitted by law, deduct any such
tax obligations from any payment of any kind otherwise due to the Participant.

         (i)      Foreign Nationals. Awards may be made to Participants who are
foreign nationals or employed outside the United States on such terms and
conditions different from those specified in the Plan as the Committee considers
necessary or advisable to achieve the purposes of the Plan or to comply with
applicable laws.

         (j)      Amendment of Award. The Committee may amend, modify or
terminate any outstanding Award, including substituting therefor another Award
of the same or a different type, changing the date of exercise or realization
and converting an Incentive Stock Option to a Nonstatutory Stock Option,
provided that the Participant's consent to such action shall be required unless
the Committee determines that the action, taking into account any related
action, would not materially and adversely affect the Participant.

                    ALKERMES, INC. 1998 EQUITY INCENTIVE PLAN

                   Incentive Stock Option Terms And Conditions

         1.       PLAN INCORPORATED BY REFERENCE . This option is issued
pursuant to the terms of the Plan and may be amended as provided in the Plan.
Capitalized terms used and not otherwise defined in this certificate have the
meanings given to them in the Plan. This certificate does not set forth all of
the terms and conditions of the Plan, which are incorporated herein by
reference. The Committee administers the Plan and its determinations regarding
the operation of the Plan are final and binding. Copies of the Plan may be
obtained upon written request without charge from the Company.

         2.       OPTION PRICE. The price to be paid for each share of Common
Stock issued upon exercise of the whole or any part of this Option is the Option
Price set forth on the face of this certificate.

         3.       EXERCISABILITY SCHEDULE. This Option may be exercised at any
time and from time to time for the number of shares and in accordance with the
exercisability schedule set forth on the face of this certificate, but only for
the purchase of whole shares. This Option may not be exercised as to any shares
after the Expiration Date.

         4.       METHOD OF EXERCISE. To exercise this Option. the Optionholder
shall deliver written notice of exercise to the Company specifying the number of
shares with respect to which the Option is being exercised accompanied by
payment of the Option Price for such shares in cash, by certified check or in
such other form, including shares of Common Stock of the Company valued at their
Fair Market Value on the date of delivery or a payment commitment of a financial
or brokerage institution. Promptly following such notice, the Company will
deliver to the Optionholder a certificate representing the number of shares with
respect to which the Option is being exercised.

         5.       RIGHTS AS A SHAREHOLDER OR EMPLOYEE. The Optionholder shall
not have any rights in respect of shares as to which the Option shall not have
been exercised and payment made as provided above. The Optionholder is an
employee-at-will unless, and only to the extent, provided in a separate written
agreement executed by the chief executive officer of the Company or his duly
authorized designee, and neither the Plan nor the grant of this Option shall be
deemed to give the Optionholder the right to continued employment or to limit
the right of the Company to discharge the Optionholder at any time.

         6.       RECAPITALIZATION, MERGERS, ETC. As provided in the Plan, in
the event of corporate transactions affecting the Company's outstanding Common
Stock, the Committee shall equitably adjust the number and kind of shares
subject to this Option and the exercise price hereunder or make provision for a
cash payment. If such transaction involves a consolidation or merger of the
Company with another entity, the sale, lease or exchange of all or substantially
all of the assets of the Company or a reorganization or liquidation of the
Company, then in lieu of the foregoing, the Committee may upon written notice to
the Optionholder provide that this Option may terminate on a date not less than
20 days after the date of such notice unless theretofore exercised. In
connection with such notice the Committee may accelerate or waive any deferred
exercise period.

         7.       OPTION NOT TRANSFERABLE. This Option is not transferable by
the Optionholder otherwise than by will or the laws of descent and distribution,
and is exercisable, during the Optionholder's lifetime, only by the
Optionholder. The naming of a Designated Beneficiary does not constitute a
transfer.

         8.       EXERCISE OF 0PTION AFTER TERMINATION OF EMPLOYMENT. If the
Optionholder's employment with (a) the Company, (b) an Affiliate, or (c) a
corporation (or parent or subsidiary corporation of such corporation) issuing or
assuming a stock option in a transaction to which section 424(a) of the Code
applies, is terminated for any reason other than by disability (within the
meaning of section 22(e)(3) of the Code) or death, the Optionholder may exercise
the rights which were available to the Optionholder at the time of such
termination only within three months from the date of termination. If the
Optionholder's employment is terminated as a result of disability, such rights
may be exercised within twelve months from the date of termination. Upon the
death of the Optionholder, his or her Designated Beneficiary shall have the
right, at any time within twelve months after the date of death, to exercise in
whole or in part any rights that were available to the Optionholder at the time

Company may, in its discretion, require (a) that the shares of Common Stock
reserved for issue upon the exercise of this Option shall have been duly listed,
upon official notice of issuance, upon any national securities exchange or
automated quotation system on which the Company's Common Stock may then be
listed or quoted, (b) that either (i) a registration statement under the
Securities Act of 1933 with respect to the shares shall be in effect, or (ii) in
the opinion of counsel for the Company, the proposed purchase shall be exempt
from registration under that Act and the Optionholder shall have made such
undertakings and agreements with the Company as the Company may reasonably
require, and (c) that such other steps, if any, as counsel for the Company shall
consider necessary to comply with any laws applicable to the issue of such
shares by the Company shall have been taken by the Company or the Optionholder,

consider necessary to comply with any law applicable to the issue of such shares
by the Company shall have been taken by the Company or the Optionholder, or
both. The certificates representing the shares purchased under this Option may
contain such legends as counsel for the Company shall consider necessary to
comply with any applicable law.

                                   ARTICLE VI

                             GRANT OF STOCK OPTIONS


         6.1      GRANTS. The Administrator shall have the authority to grant to
any person, to the extent eligible under Article V, one or more Incentive Stock
Options, Non-Qualified Stock Options, or both types of Stock Options. To the
extent that any Stock Option does not qualify as an Incentive Stock Option
(whether because of its provisions or the time or manner of its exercise or
otherwise), such Stock Option or the portion thereof which does not qualify as
an Incentive Stock Option shall constitute a separate Non-Qualified Stock
Option.

         6.2      INCENTIVE STOCK OPTIONS. Anything in the Plan to the contrary
notwithstanding, no term of this Plan relating to Incentive Stock Options shall
be interpreted, amended or altered, nor shall any discretion or authority
granted under the Plan be exercised, so as to disqualify the Plan under Section
422 of the Code, or, without the consent of the Participants affected, to
disqualify any Incentive Stock Option under such Section 422.

         6.3      TERMS OF OPTIONS. Options granted under the Plan shall be
subject to the following terms and conditions and shall contain such additional
terms and conditions, not inconsistent with the terms of the Plan, as the
Administrator shall deem desirable:

                  (a)      STOCK OPTION CERTIFICATE. Each Stock Option shall be
evidenced by, and subject to the terms of, a Stock Option Certificate executed
by the Company. The Stock Option Certificate shall specify whether the Option is
an Incentive Stock Option or a Non-Qualified Stock Option, the number of shares
of Common Stock subject to the Stock Option, the option price, the option term,
and the other terms and conditions applicable to the Stock Option.

                  (b)      OPTION PRICE. The option price per share of Common
Stock to be delivered upon exercise of a Stock Option shall be determined by the
Administrator at the time of grant, but shall not be less than 100% of the Fair
Market Value of a share of Common Stock on the date the Option is granted.

                  (c)      OPTION TERM. The term of each Stock Option shall be
fixed by the Administrator at the time of grant, but no Stock Option shall be
exercisable more than ten years after the date it is granted.

                  (d)      EXERCISABILITY. Stock Options shall be exercisable at
such time or times and subject to such terms and conditions as shall be
determined by the Administrator at the time of grant; provided, however, that
the Administrator may waive any installment




                                        5


<PAGE>   6
exercise or waiting period provisions, in whole or in part, at any time after
the date of grant, based on such factors as the Administrator shall deem
appropriate in its sole discretion.

                  (e)      METHOD OF EXERCISE. Subject to such installment
exercise and waiting period provisions as may be imposed by the Administrator,
Stock Options may be exercised in whole or in part at any time during the option
term by delivering to the Company written notice of exercise specifying the
number of shares of Common Stock to be purchased and the aggregate option price
therefor. The notice of exercise shall be accompanied by payment in full of the
option price and, if requested by the Company, by the representation described
in Section 9.2. Payment of the option price may be made (i) in cash or by check
payable to the Company, (ii) unless otherwise provided by the Administrator on
the date of grant, in shares of Common Stock duly owned by the Participant (and
for which the Participant has good title, free and clear of any liens and
encumbrances) or (iii) unless otherwise provided by the Administrator on the
date of grant, by reduction in the number of shares of Common Stock issuable
upon such exercise, based, in each case, on the Fair Market Value of the Common
Stock on the date of exercise. Upon payment in full of the option price and
satisfaction of the other conditions provided herein, a stock certificate
representing the number of shares of Common Stock to which the Participant is
entitled shall be issued and delivered to the Participant.

                  (f)      DEATH. Unless otherwise determined by the
Administrator on or after the date of grant, in the event of a Participant's
Termination of Employment by reason of death, any Stock Option held by such
Participant which was exercisable on the date of death may thereafter be
exercised by the legal representative of the Participant's estate until the
earlier of one year after the date of death or the expiration of the stated term
of such Stock Option, and any Stock Option not exercisable on the date of death
shall be forfeited.

                  (g)      DISABILITY. Unless otherwise determined by the
Administrator on or after the date of grant, in the event of a Participant's
Termination of Employment by reason of Disability, any Stock Option held by such
Participant that was exercisable on the date of such Termination of Employment
may thereafter be exercised by the Participant until the earlier of one year
after such date or the expiration of the stated term of such Stock Option, and
any Stock Option not exercisable on the date of Termination of Employment shall
be forfeited. If the Participant dies during such one-year period, any
unexercised Stock Options held by the Participant at the time of death may
thereafter be exercised by the legal representative of the Participant's estate
until the earlier of one year after the date of the Participant's death or the
expiration of the stated term of such Stock Option. If an Incentive Stock Option
is exercised after the expiration of the exercise periods that apply for
purposes of Section 422 of the Code, such Stock Option will thereafter be
treated as a Non-Qualified Stock Option.

                  (h)      TERMINATION OF EMPLOYMENT. Unless otherwise
determined by the Administrator on or after the date of grant, in the event of a
Participant's Termination of




                                        6


<PAGE>   7
Employment by reason of retirement or for any reason other than death or
Disability, any Stock Option held by such Participant which was exercisable on
the date of such Termination of Employment may thereafter be exercised by the
Participant until the earlier of three months after such date or the expiration
of the stated term of such Stock Option, and any Stock Option not exercisable on
the date of Termination of Employment shall be forfeited.

                  (i)      CHANGE OF CONTROL. In the event of a Change of
Control, all outstanding Stock Options shall immediately become fully
exercisable, and upon payment by the Participant of the option price (and, if
requested, delivery of the representation described in Section 9.2), a stock
certificate representing the Common Stock covered thereby shall be issued and
delivered to the Participant; provided, however, that the exercisability of the
Stock Options shall not be accelerated if, in the opinion of the Board, such
acceleration would prevent pooling of interests accounting for the change of
control transaction and such accounting treatment is desired by the parties to
such transaction.

                  (j)      NON-TRANSFERABILITY OF OPTIONS. Unless otherwise
determined by the Administrator on or after the date of grant, Stock Options
shall not be transferrable by the Participant otherwise than by will or by the
laws of descent and distribution, and all Stock Options shall be exercisable,
during the Participant's lifetime, only by the Participant.

                  (k)      INCENTIVE STOCK OPTION LIMITATIONS. To the extent
that the aggregate Fair Market Value (determined as of the date of grant) of the
Common Stock with respect to which Incentive Stock Options are exercisable for
the first time by the Participant during any calendar year under the Plan and/or
any other stock option plan of the Company or any Subsidiary or parent
corporation (within the meaning of Section 424 of the Code) exceeds $100,000,
such Options shall be treated as Options which are not Incentive Stock Options.

                           Should any of the foregoing provisions not be
necessary in order for the Stock Options to qualify as Incentive Stock Options,
or should any additional provisions be required, the Board may amend the Plan
accordingly, without the necessity of obtaining the approval of the shareholders
of the Company.

                  (l)      TEN-PERCENT SHAREHOLDER RULE. Notwithstanding any
other provision of the Plan to the contrary, no Incentive Stock Option shall be
granted to any person who, immediately prior to the grant, owns stock possessing
more than ten percent of the total combined voting power of all classes of stock
of the Company or any Subsidiary or parent corporation (within the meaning of
Section 424 of the Code), unless the option price is at least 110% of the Fair
Market Value of the Common Stock on the date of grant and the Option, by its
terms, expires no later than five years after the date of grant.

         6.4      RIGHTS AS SHAREHOLDER. A Participant shall not be deemed to be
the holder of Common Stock, or to have any of the rights of a holder of Common
Stock, with




                                       7

respect to shares subject to an Option, unless and until the Option is exercised
and a stock certificate representing such shares of Common Stock is issued to
the Participant.


                                   ARTICLE VII

                            TERMINATION OR AMENDMENT

         7.1      TERMINATION OR AMENDMENT OF PLAN. The Board may at any time
amend, discontinue or terminate the Plan or any part thereof (including any
amendment deemed necessary to ensure that the Company may comply with any
regulatory requirement referred to in Article IX) or amend any Option previously
granted, prospectively or retroactively (subject to Article IV); provided,
however, that, in either case unless otherwise required by law, the rights of a
Participant with respect to Options granted prior to such amendment,
discontinuance or termination may not be impaired without the consent of such
Participant and, provided further, that the Company will seek the approval of
the Company's shareholders for any amendment if such approval is necessary to
comply with the Code, Federal or state securities laws or any other applicable
rules or regulations.



                                  ARTICLE VIII

                                  UNFUNDED PLAN

         8.1      UNFUNDED STATUS. The Plan is intended to constitute an
"unfunded" plan for incentive compensation. With respect to any payment not yet
made to a Participant by the Company, nothing contained herein shall give any
such Participant any rights that are greater than those of a general creditor of
the Company.


                                   ARTICLE IX

                               GENERAL PROVISIONS

         9.1      NONASSIGNMENT. Except as otherwise provided in the Plan, any
Option granted hereunder and the rights and privileges conferred thereby may not
be sold, transferred, assigned, pledged or hypothecated in any way (whether by
operation of law or otherwise), and shall not be subject to execution,
attachment or similar process. Upon any attempt to transfer, assign, pledge,
hypothecate or otherwise dispose of an Option, right or privilege contrary to
the provisions hereof, or upon the levy of any attachment or similar process
thereon, such Option and the rights and privileges conferred thereby shall
immediately terminate and the Option shall immediately be forfeited to the
Company.

         9.2      LEGEND. The Company may require each person acquiring shares
upon exercise of an Option to represent to the Company in writing that the
Participant is acquiring the shares for the Participant's own account and
without a view to the distribution thereof. The stock certificates representing
such shares may include any legend which the Company deems appropriate to
reflect any restrictions on transfer.

         All certificates representing shares of Common Stock delivered under
the Plan shall be subject to such stop transfer orders and other restrictions as
the Company may deem advisable under the rules, regulations and other
requirements of the Securities and Exchange Commission, any stock exchange or
stock market upon which the Common Stock is then listed or traded, any
applicable Federal or state securities law, and any applicable corporate law,
and the Company may cause a legend or legends to be put on any such certificates
to make appropriate reference to such restrictions.

         9.3      OTHER PLANS. Nothing contained in the Plan shall prevent the
Company from adopting other or additional compensation arrangements, and such
arrangements may be either generally applicable or applicable only in specific
cases.

         9.4      NO RIGHT TO EMPLOYMENT. Neither the Plan nor the grant of any
Option shall give any Participant or other officer, employee, consultant or
director any right with respect to continuance of office, employment, consulting
relationship or directorship, as the case may be, with the Company or any
Subsidiary, nor shall the Plan impose any limitation on the right of the Company
or any Subsidiary by which a Participant is employed to terminate a
Participant's office, employment or consulting relationship at any time. Neither
the Plan nor the grant of any Option shall give any director the right to
continue as a member of the Board or obligate the Company to nominate any
director for reelection by the Company's shareholders.

         9.5      WITHHOLDING OF TAXES. The Company shall have the right to
reduce the number of shares of Common Stock otherwise deliverable upon exercise
of an Option by an amount that would have a Fair Market Value equal to the
amount of all Federal, state and local taxes required to be withheld, or to
deduct the amount of such taxes from any cash payment otherwise to be made to
the Participant, pursuant to the Plan or otherwise. In connection with such
withholding, the Company may make such arrangements as are consistent with the
Plan as it may deem appropriate.

         9.6      LISTING AND OTHER CONDITIONS.

                  (a)      If the Common Stock is listed on a national
securities exchange or Nasdaq, the issuance of any shares of Common Stock upon

exchange or Nasdaq. The Company shall have no obligation to issue any shares of
Common Stock unless and until such shares are so

listing has been effected.

                  (b)      If at any time counsel to the Company shall be of the
opinion that any sale or delivery of shares of Common Stock upon exercise of an
Option is or may in the circumstances be unlawful or result in the imposition of
excise taxes under the statutes, rules or regulations of any applicable
jurisdiction, the Company shall have no obligation to make such sale or
delivery, or to make any application or to effect or to maintain any
qualification or registration under the Securities Act of 1933, as amended, or
otherwise with respect to shares of Common Stock or Options, and the right to
exercise any Option shall be suspended until, in the opinion of such counsel,
such sale or delivery shall be lawful or shall not result in the imposition of
excise taxes.

                  (c)      Upon termination of any period of suspension under
this Section 9.6, any Option affected by such suspension which shall not then
have expired or terminated shall be reinstated as to all shares available before
such suspension and as to shares which would otherwise have become available
during the period of such suspension, but no such suspension shall extend the
term of any Option.

         9.7      GOVERNING LAW. The Plan and actions taken in connection
herewith shall be governed and construed in accordance with the laws of the
Commonwealth of Pennsylvania without regard to the conflict of law principles
thereof.

         9.8      CONSTRUCTION. Wherever any words are used in the Plan in the

also used in the plural form in all cases where they would so apply.

         9.9      LIABILITY OF THE BOARD. No member of the Board nor any
employee of the Company or any of its Subsidiaries shall be liable for any act
or action hereunder, whether of omission or commission, by any other member of
the Board or officer or employee or by any agent to whom duties in connection
with the administration of the Plan have been delegated or, except in
circumstances involving bad faith, gross negligence or fraud, for anything done
or omitted to be done by himself or herself.

         9.10     COSTS. The Company shall bear all expenses incurred in
administering the Plan, including expenses related to the issuance of Common
Stock upon exercise of Options.

         9.11     SEVERABILITY. If any part of the Plan shall be determined to
be invalid or void in any respect, such determination shall not affect, impair,
invalidate or nullify the remaining provisions of the Plan which shall continue
in full force and effect.

(the "Effective Date") between ALKERMES CONTROLLED THERAPEUTICS, INC. a
Pennsylvania corporation ("Alkermes"), located at 64 Sidney Street, Cambridge,
Massachusetts 02139 and GENENTECH, INC., a Delaware corporation ("Genentech"),
located at 1 DNA Way, South San Francisco, California 94080.

         Alkermes and Genentech entered into a License Agreement, effective
November 13, 1996, and as amended June 16, 1997, December 29, 1998, and March

sustained release of such molecules when injected under the skin.

         Alkermes and Genentech wish to continue their collaboration to complete
the development of the 1st generation formulation and to incorporate Alkermes'
ProLease technology into a 2nd generation formulation of recombinant human

Product as specifically set forth in this Agreement. In order to provide
Alkermes with such funding, Genentech and Alkermes, Inc. a Pennsylvania
corporation and the parent corporation of Alkermes ("Alkermes Parent"), have
entered into that certain Stock Purchase Agreement of even date herewith (the
"Stock Purchase Agreement") pursuant to which Genentech agrees to buy and
Alkermes Parent agrees to sell shares of its Preferred Stock.

         Therefore, Alkermes and Genentech agree as follows:

identifiable.

reimbursement approvals), licenses, registrations or authorizations of any
federal, state or local regulatory agency, department, bureau or other
governmental entity, necessary for the manufacture and sale of a Licensed
Product in a regulatory jurisdiction.

         1.28 "TERRITORY" shall mean all of the countries in the world except

or certificates reasonably requested by Alkermes.

         3.2      ROYALTIES

                  (a) ROYALTIES PAYABLE BY GENENTECH. Genentech shall pay
royalties to Alkermes of XXXXXXXXXXXXXXXXX of Net Sales of Licensed Products
sold by Genentech or by Genentech's Distributors, in each country in the United
States and the Territory.

                  (b) OFFSETS FOR THIRD PARTY ROYALTIES. The royalties otherwise
payable by Genentech hereunder shall be reduced by XXXXXXXXXXXXXXXXXXXX of the
amounts that Genentech must pay to any third party due to manufacture, use, or
sale of Licensed Products and caused by the fact that the Licensed Product
incorporates the Alkermes Technology, on a country-by-country basis; provided,
however, that in no event shall the royalties payable hereunder be reduced by
more than XXXXXXXXXXXXXXXXXXX.

                  (c) MILESTONE CREDITS. XXXXXXXXXXXXXXXXXXX of the milestone
payments marked with an asterisk made with respect to the events described in
Section 3.1 shall be creditable by Genentech against future royalties to be paid
to Alkermes pursuant to this Section 3.2.

                  (d) ROYALTY REDUCTION. Until December 14, 2000, the royalties
otherwise payable by Genentech hereunder shall be reduced to XXXXXXXXXXXXXXX of
Net Sales of Licensed Products sold by Genentech or by Genentech's Distributors,
effective automatically if (and when) Alkermes commences development and
commercialization, outside of the scope of the collaboration with Genentech
pursuant to this Agreement, of any pharmaceutical formulation of human growth
hormone using any Alkermes Technology and any human growth hormone or analogues
thereof (or nucleic acids meant to be incorporated into cells, causing
production of human growth hormone or analogues thereof) not within the
Genentech Technology. Any such pharmaceutical formulation is referred to herein
as a "Competing Product". Such development and commercialization shall be deemed
to include commencement of any human clinical trial of any Competing Product,
and Alkermes shall be required to notify Genentech of the commencement of any
such trial not later than the date of enrollment of the first subject in such
trial. However, the automatic royalty reduction herein shall apply even if
Alkermes fails to provide such notice, and if Genentech continues to pay
royalties at the higher rate under Section 3.2(a) for any time period during
which it later learns that Alkermes had commenced development and
commercialization of a Competing Product, Genentech shall be entitled to offset
against any future payments owed under


                                       10

this Agreement the full amount of any excess royalties paid to Alkermes during
such time period that the reduced royalty rate herein should have applied (plus
interest thereon at a rate equal to XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX.


         3.3 MODE OF PAYMENT OF ROYALTIES. For purposes of determining when a
sale of a Licensed Product occurs, the sale shall be deemed to occur on the
earlier of: (i) the date the Licensed Product is shipped, or (ii) the date of
the invoice to the purchaser of the Licensed Product. All royalty payments shall
be made within ninety (90) days of the end of each calendar quarter in which the
sale was made. Such royalty payments shall be accompanied by a detailed
statement that shall include for each country in which sales of Licensed
Products occurred: the gross sales (if available) and Net Sales in each
country's currency or in the Euro, if applicable; the applicable royalty rate;
the royalties payable in each country's currency or the Euro, if applicable,
including an accounting of all deductions taken in the calculation of Net Sales
and a separate accounting for all Combination Products sold and the formulas
used in the calculation of royalties owed thereon; the applicable exchange rate
to convert from each country's currency or the Euro, if applicable, to United
States Dollars; and the royalties payable in United States Dollars. Royalty
payments shall first be calculated in the currency in which sales took place or
in the Euro, if applicable, and then converted to United States Dollars based on
the spot rate as reported by Reuters at the end of each calendar quarter in
which the sale was made. All royalty payments hereunder shall be made to
Alkermes in United States Dollars by bank wire transfer in immediately available
funds to such account designated by Alkermes. Genentech shall provide notice at
least five (5) days prior to the wire transfer date of the amount of payment,
the nature of the payment (with reference to the applicable section of this
Agreement) and the date of receipt of good funds. Such notice should be given to
the Treasurer of Alkermes at the address set forth in the Notices and Deliveries
Section of this Agreement or such other address directed by Alkermes. All
payments hereunder shall be made net of any withholding taxes, duties, levies,
fees or charges required to be withheld under the law, on behalf of the other
party. Genentech shall make any withholding payments due on behalf of Alkermes
and shall promptly provide Alkermes with written documentation of any such
payment sufficient to satisfy any requirements of the United States Internal
Revenue Service related to an application by Alkermes for a foreign tax credit
for such payment. Genentech agrees to take reasonable and lawful steps as
Alkermes may request to minimize the amount of tax to which payments to Alkermes
are subject, if such steps are not detrimental to Genentech.

         3.4 RESTRICTIONS ON PAYMENT. If by law, regulations or fiscal policy of
a particular country, remittance of royalties in United States Dollars is
restricted or


                                       11

forbidden, notice thereof will be promptly given to Alkermes, and payment of the
royalty shall be made by the deposit thereof in local currency to the credit of
Alkermes in a recognized banking institution designated by Alkermes. When in any
country the law or regulations prohibit both the transmittal and deposit of
royalties on sales in such a country, royalty payments shall be suspended for as
long as such prohibition is in effect and as soon as such prohibition ceases to
be in effect, all royalties that Genentech would have been under obligation to
transmit or deposit but for the prohibition, shall forthwith be deposited or
transmitted promptly to the extent allowable. Genentech will first obtain
written agreement from Alkermes before selling a Licensed Product in a country
known to Genentech to restrict or forbid remittance of royalties in United
States Dollars.

         3.5 RECORDS RETENTION. Genentech agrees to keep for at least three (3)
years, records of all sales of Licensed Products in sufficient detail to permit
Alkermes to confirm the accuracy of Genentech's royalty calculations. At the
request of, upon at least five (5) days' prior written notice, and at the
expense of Alkermes, Genentech shall permit a nationally recognized,
independent, certified public accountant appointed by Alkermes and reasonably
acceptable to Genentech to examine these records solely to the extent necessary
to verify such calculations, provided that such accountant has entered into a
confidentiality agreement with Genentech substantially similar to the
confidentiality provisions of this Agreement, limiting the use and disclosure of
such information to purposes germane to this Section 3.5. Results of any such
examination shall be made available to Alkermes and to Genentech. If such
examination reveals an underpayment of royalties by ten percent (10%) or more,
Genentech shall pay all costs of such examination. In the event such accountant
concludes that additional royalties are owed, the additional royalties shall be
paid within thirty (30) days of the date Alkermes delivers to Genentech the
accountant's written report reflecting such conclusion. This Section 3.5 shall
survive any termination of this Agreement for three (3) years.

         3.6 MILESTONE PAYMENTS FOR CLINICAL DEVELOPMENT AND PROCESS SCALE-UP.
Genentech shall pay Alkermes the amounts specified below if the listed events
are completed on or before the listed dates and Alkermes performs the clinical
development and process scale-up work necessary for the completion of the
particular event.

4.       DEVELOPMENT PLAN

         The Parties have established a Joint Development Committee ("JDC") to
provide oversight on all aspects of product development and to review the
progress of preclinical development, clinical development and regulatory
filings. The JDC will have three representatives appointed by each of Genentech
and Alkermes. Such representatives will have expertise in any of the areas of
clinical development, process sciences, manufacturing, marketing or regulatory
affairs; however, the JDC members will not be personally responsible for
implementing the Development Plans. Either Party may replace any or all of its
representatives at any time upon written notice to the other Party. The JDC will
meet at least once each calendar quarter or at such other times as directed by
Genentech. While the Alkermes representatives may comment on any development and
regulatory filing plans, Genentech shall have the final say and shall direct the
process, except that Alkermes shall make the final determination if there is a
disagreement on a matter that would lead to a substantial increase in the total
manpower committed by Alkermes or the scheduling of Alkermes critical facilities
when the scheduling is less than one year in advance.

         4.1 CLINICAL DEVELOPMENT OF 1ST GENERATION LICENSED PRODUCT BY
ALKERMES. Alkermes shall assemble all data and documentation and Genentech shall
file for Regulatory Approval with the FDA in the United States for the 1st
Generation Formulation of Licensed Product. The Parties agree that obtaining
Regulatory Approval in the United States for the 1st Generation Formulation is
the highest priority activity for both Parties under this Agreement. Exhibit C
sets forth the activities to be completed with respect to the NDA filing.
Changes in the project scope, timelines or costs shall be brought to the
attention of the JDC for review and the JDC shall make recommendations regarding
appropriate changes or additions to Exhibit C. Genentech shall make all final
decisions on any changes or additions to Exhibit C.

         4.2 PRECLINICAL DEVELOPMENT OF 2ND GENERATION LICENSED PRODUCT.
Alkermes shall perform Preclinical Research for the 2nd Generation Formulation
of the Licensed Product as set forth in Exhibit B attached hereto. Changes in
the project scope, timelines or costs shall be brought to the attention of the
JDC for review and the JDC shall make recommendations regarding appropriate
changes or additions to Exhibit B. Genentech shall make all final decisions on
any changes or additions to Exhibit B. Genentech shall file and hold the IND for
the 2nd Generation Formulation of Licensed Product as described in Exhibit B.

         4.3 CLINICAL DEVELOPMENT OF 2ND GENERATION LICENSED PRODUCT

REQUEST. REDACTED MATERIAL IS MARKED WITH "X" AND HAS BEEN FILED SEPARATELY WITH
THE SECURITIES AND EXCHANGE COMMISSION.



                  (a) Alkermes shall sponsor clinical trials for the 2nd
Generation Formulation as provided in Exhibit B (the "Clinical Trials").
Alkermes shall be solely responsible for and shall use its commercially
reasonable efforts to perform the Clinical Trials as described in Exhibit B. For
the purposes of this Agreement, "commercially reasonable" efforts shall mean
those efforts expended by Alkermes on its own high priority projects. Alkermes
shall prepare in collaboration with Genentech all documentation necessary for
associated filings with regulatory agencies and Genentech shall make all such
filings as described in Exhibit B. However, Genentech may, in its sole
discretion, determine to have Alkermes make filings for Regulatory Approval. The
JDC will oversee clinical development and regulatory filings and carry out plans
for clinical development and regulatory filings communicated to it by Genentech.
Exhibit B sets forth the Clinical Trials to be conducted, along with the
anticipated timeline, requirements and estimated costs for the Clinical Trials
and associated regulatory filings. If there are changes in project scope,
timelines or costs, the JDC shall be informed and shall review and suggest
necessary changes or additions. Genentech shall make all final decisions on any
changes or additions to Exhibit B.

                  (b) At any time, if, in Genentech's sole discretion, Genentech
believes that Alkermes is not using its commercially reasonable efforts to
complete or is not capable of completing any of the clinical development tasks
for which Alkermes is given responsibility, Genentech may so notify Alkermes and
complete such task itself.

         4.4 SUPPLY OF CLINICAL MATERIAL BY ALKERMES. Alkermes shall be
responsible for, and shall use its commercially reasonable efforts to, supply
all clinical needs and requirements of the 1st and 2nd Generation Formulations
of Licensed Product. Such Licensed Product shall be produced under GMP and all
other applicable laws and regulations. Exhibit B attached hereto sets forth
Alkermes' estimated timeline, requirements, and costs for supplying the 2nd
Generation Formulation of the Licensed Product for the Clinical Trials. Alkermes
will provide, and the Parties will agree upon, additions to Exhibit B for other
clinical trials of Licensed Products. Exhibit C attached hereto sets forth
Alkermes' estimated timeline, requirements, and costs for supplying the 1st
Generation Formulation of Licensed Products for ongoing clinical studies and
qualification lots for NDA submission.

         4.5 SCALE-UP OF THE MANUFACTURING PROCESS BY ALKERMES. Alkermes shall
be responsible for, and shall use its commercially reasonable efforts to, scale
up the process for producing the 1st and 2nd Generation Formulations of Licensed
Product for both clinical and (unless Genentech manufactures commercial Licensed
Product pursuant to Section 5) commercial requirements, provided that Genentech
supplies sufficient quantities of human growth hormone (at Genentech's expense)
to enable

Alkermes to do so. Exhibit B attached hereto sets forth the anticipated
timeline, requirements and costs for scaling-up the manufacturing process for
making the 2nd Generation Formulation of Licensed Product for clinical and
commercial use. Genentech shall not be responsible for any of Alkermes' capital
cost of its facilities except as otherwise set forth in Exhibit B or approved by
the JDC for the facility in which commercial Licensed Product(s) are to be
manufactured. The Parties will prepare and agree upon a separate document
setting forth the anticipated timeline, requirements and costs for scaling-up
the manufacturing process for other applications of the Licensed Product.

         4.6 FUNDING FOR PRECLINICAL DEVELOPMENT, CLINICAL DEVELOPMENT, SUPPLY
AND SCALE-UP OF LICENSED PRODUCTS.

                  (a) In connection with the development of the Licensed
Products, the 1999/2000 Budget is attached hereto as Exhibit D and the proposed
2001/2002 Development Budget is attached hereto as Exhibit E. The 2001/2002
Development Budget shall be reviewed by the JDC prior to the fourth calendar
quarter of the year 2000 and the JDC shall approve such budget or make
recommendations for changes or additions. Genentech shall make the final
decision regarding any changes or additions to the 2001/2002 Development Budget.

                  (b) Genentech shall fund XXXXXXXXXXXXXXXXXXXXXXXXXXXXX towards
activities related to the filing for Regulatory Approval with the FDA of the 1st
Generation Formulation of the Licensed Product and for the development of the
2nd Generation Formulation of the Licensed Product in accordance with the agreed
upon Development Plans and 1999/2000 Development Budget. This amount shall be
funded to Alkermes through the purchase of Preferred Stock under the Stock
Purchase Agreement and the payment of the Bonus Milestone Payment, if any. The
1999/2000 Budget shall be reviewed by the Parties on a quarterly basis to update
the budget forecast and to assess the need for additional funding. Any increase
in the amount of funding shall require the agreement of both Parties and such
funding shall be through the purchase of additional Preferred Stock. Alkermes
shall submit a detailed monthly report to Genentech within four (4) weeks after
the end of each month during which it expends Development Funds in 1999 and
2000. Such report shall set forth the activities completed, including
development and scale-up efforts and supply of 1st and 2nd Generation
Formulations for clinical use, the Full Time Equivalent (FTE) utilization rate
broken down by functional area and the costs for such activities, which shall be
reasonably in accordance with amounts previously agreed upon in the 1999/2000
Development Budget by the JDC for such activities. In the event of a change of
control as described in Section 9.9 herein, exercise of the rights described in
the Discontinuation Agreement prior to December 31, 2000 shall result in the
funding of the

Development Plans pursuant to paragraph (c) below rather than through this
paragraph (b).

                  (c) Genentech shall reimburse the costs incurred by Alkermes
in accordance with the Development Plans and the 2001/2002 Development Budget,
and for 1st and 2nd Generation Formulations of Licensed Product supplied for
clinical use in 2001 and 2002, at Alkermes' actual cost, as determined by
Alkermes in accordance with the FTE rate agreed upon for such years by the JDC
at the beginning of each Alkermes fiscal year, to be consistently applied
throughout such years, plus the external costs of performing any clinical trials
agreed upon by the JDC. In 2001 and 2002, Alkermes shall submit a detailed
monthly report to Genentech as described in Section 4.6 (b) above, together with
an invoice for the total amount to be reimbursed by Genentech, which shall be
reasonably in accordance with the amounts agreed upon by the JDC for the
2001/2002 Development Budget. Genentech shall reimburse Alkermes' costs within
thirty (30) days of receiving each invoice. With regard to supply of Licensed
Product for clinical use by Genentech, Alkermes will only ship to an invoice
Genentech for Licensed Product ordered by Genentech pursuant to binding purchase
orders.

                  (d) Alkermes will keep reasonably detailed records of its
costs of performing the obligations set forth in this Agreement, as determined
by Alkermes consistent with the FTE rate methods used by Alkermes in connection
with the prior research and development activities conducted in collaboration
with Genentech plus other external costs as agreed upon by the JDC.

         4.7 DEVELOPMENT DUE DILIGENCE. Alkermes shall use its commercially
reasonable efforts to meet the timelines set forth in the Development Plans.

5.       MANUFACTURE OF LICENSED PRODUCT

         5.1 MANUFACTURE BY ALKERMES. Alkermes shall be responsible for, and
shall use its commercially reasonable efforts to, supply all clinical and
commercial requirements of Licensed Product in either final vial form or bulk
form as agreed upon by the Parties. The provisions governing production of
material for clinical trials are set forth in Section 4.4. The provisions
governing the production of commercial material shall be set forth in a Supply
Agreement to be entered into by the Parties on or before June 30, 1999. The
price of supply of commercial material in the Supply Agreement will be a
purchase price per vial (or similar quantity) of XX of the gross invoiced sales
price per vial (or similar quantity) used in the calculation of Net Sales less
the deductions used in the calculation of Net Sales. Prior to Commercial
Introduction, the purchase price will be based on the expected gross invoiced
sales price and expected deductions

upon Commercial Introduction. If Alkermes supplies only bulk product in this
situation, Genentech shall be entitled to deduct its Fully Burdened
Manufacturing Cost of filling and finishing Licensed Product from the amount
otherwise payable to Alkermes. Genentech will supply the necessary amount of
growth hormone free-of-charge to enable Alkermes to fulfill its supply
obligations. Alkermes will permit Genentech representatives to review
periodically Alkermes' quality control procedures and records, and to visit
Alkermes' facilities, upon prior written notice to Alkermes and at reasonable
times for quality assurance purposes.

         5.2 MANUFACTURE BY GENENTECH. If in Genentech's reasonable opinion,
Alkermes is unable to manufacture all clinical and commercial quantities of any
Licensed Product, Alkermes shall transfer to and fully enable Genentech with the
then most current version of all materials, regulatory filings, knowhow,
reagents and expertise necessary for Genentech to undertake the manufacture of
Licensed Products. All transfers of materials and information to Genentech shall
be free of charge to Genentech if the transfer occurs due to a breach of this
Agreement by Alkermes. If the transfer occurs due to any other inability to
perform of Alkermes, Genentech shall reimburse Alkermes for all reasonable costs
of transfer of materials and information. Alkermes shall continue to manufacture
Licensed Product until, in Genentech's reasonable opinion, Genentech is fully
enabled to manufacture. Manufacture of Licensed Product may be done partially by
Alkermes and partially by Genentech in this situation. If that is the case, and
the situation is caused by a breach of this Agreement by Alkermes, the price
otherwise payable by Genentech to Alkermes under the provisions of Section 5.1
shall be reduced to XXXX of the gross invoiced sales price per vial (or similar
quantity) used in the calculation of Net Sales less the deductions used in the
calculation of Net Sales. Otherwise, the price otherwise payable will be
prorated based on the percentage of the total manufacture of Licensed Product
being done by each Party.

6. COMMERCIALIZATION. Genentech agrees to pursue a diligent sales and marketing
effort for a Licensed Product to be sold by Genentech relative to other products
of similar commercial potential that are being sold and marketed by Genentech. A
default by Genentech with respect to pursuing a diligent sales and marketing
effort for a Licensed Product in one country shall not constitute a default by
Genentech with respect to any other country.

7. REPRESENTATIONS AND WARRANTIES

         7.1 REPRESENTATIONS AND WARRANTIES OF ALKERMES. Alkermes hereby
represents and warrants that:

8.       CONFIDENTIALITY

         8.1 DISCLOSED CONFIDENTIAL INFORMATION. In the course of performance of
this Agreement, one Party may disclose to the other or receive written
information from the other relating to the subject matter of this Agreement
which information, if so


                                       18

THE SECURITIES AND EXCHANGE COMMISSION.



identified in writing either pursuant to this Section 8.1 or otherwise upon
disclosure, shall be considered the disclosing Party's "Disclosed Confidential
Information." Each Party agrees that it will take the same steps to protect the
confidentiality of the other Party's Disclosed Confidential Information as it
takes to protect its own proprietary and confidential information. Each Party
shall protect and keep confidential and shall not use, publish or otherwise
disclose to any third party, except as contemplated by this Agreement or with
the other Party's written consent, the other Party's Disclosed Confidential
Information for a period of five (5) years from the date of termination of this
Agreement.

         8.2 SHARED CONFIDENTIAL INFORMATION. In the course of performance of
this Agreement, the Parties may jointly develop, invent or discover information,
substances or processes, which shall be considered the "Shared Confidential
Information" except as otherwise set forth in Section 9.6. Each Party agrees
that it will take the same steps to protect the confidentiality of the Shared
Confidential Information as it takes to protect its own proprietary and
confidential information. Each Party shall protect and keep confidential and
shall not publish or otherwise disclose to any third party, except as
contemplated by this Agreement or with the other Party's written consent, the
Shared Confidential Information for a period of five (5) years from the date of
termination of this Agreement. Each Party may, however, use any Shared
Confidential Information for any purpose; provided that such use shall not be
deemed a license or a grant of any additional right or license other than or in
addition to the right and license granted in Section 2 of this Agreement.

         8.3 PERMITTED DISCLOSURE. In addition, each Party shall be entitled to
disclose, under a binder of confidentiality containing provisions as protective
as this Section 8, "Confidential Information," which shall include Disclosed
Confidential Information and Shared Confidential Information, to consultants and
other third parties for any purpose provided for in this Agreement. The Parties
shall consult prior to the submission of any manuscript for publication if the
publication will contain any Confidential Information of the other Party unless
the laws and regulations applicable to the third party submitting such
manuscript prohibit such consultation. Such consultation shall include providing
a copy of the proposed manuscript to the other Party at least sixty (60) days
prior to the proposed date of submission to a publisher, incorporating
appropriate changes proposed by the other Party into the manuscript submission
and deletion of all Confidential Information of which such Party does not agree
to the publication. The foregoing notwithstanding, Confidential Information may
be disclosed as a part of a patent application filed on inventions made under
this Agreement and during any official proceeding before a court or governmental
agency if reasonably related and necessary to that proceeding. For the purpose
of this Agreement, Confidential Information shall not include such information
that:

                  (i) was known to the receiving Party at the time of
disclosure; or

                  (ii) was generally available to the public or was otherwise
part of the public domain at the time of disclosure or became generally
available to the public or otherwise part of the public domain after disclosure
other than through any act or omission of the receiving Party in breach of this
Agreement; or

                  (iii) became known to the receiving Party after disclosure
from a source that had a lawful right to disclose such information to others; or

                  (iv) was independently developed by the receiving Party where
such independent development can be established by written documentation.

         8.4 INTEGRATION. This Section 8 supersedes any confidential disclosure
agreement between the Parties as to the subject matter hereof. Any confidential
information under any such agreement shall be treated as Confidential
Information hereunder.

9.       TERM; TERMINATION

         9.1 TERM; TERMINATION AT FULL TERM. This Agreement shall commence as of
the Effective Date and, except as provided in the next sentence or unless sooner
terminated as provided hereunder, shall terminate on a country-by-country basis
on the later of (i) 10 years after Commercial Introduction in that country, or
(ii) the expiration of the last Valid Claim of an Alkermes Patent in that
country. Notwithstanding any termination at the full term of this Agreement,
which shall occur upon termination as described in the preceding sentence in the
United States and each country in the Territory, or termination as otherwise
provided in this Section 9, the provisions of Sections 8, 10, 11 and 12 will not
terminate on said date but will continue in full effect. Upon termination of the
royalty obligations in any country, Genentech shall thereafter have in
perpetuity a fully paid up, royalty-free exclusive license in that country under
the Alkermes Technology to import, make, have made, use, offer for sale and sell
Licensed Products in the Field of Use without any accounting to Alkermes.

         9.2 UNILATERAL TERMINATION. Genentech shall have the right following
ninety (90) days written notice to Alkermes to terminate this Agreement at any
time for any reason except for material breach by Alkermes, which shall be
governed by Section 9.3 hereof. In the event that a Licensed Product has
received Regulatory Approval and Alkermes is manufacturing such Licensed Product
for commercial sale, Genentech may so terminate this Agreement only after
providing six (6) months written notice. In any


                                       20

REQUEST. REDACTED MATERIAL IS MARKED WITH "X" AND HAS BEEN FILED SEPARATELY WITH
THE SECURITIES AND EXCHANGE COMMISSION.



event, Alkermes shall be allowed to spend Development Funds or, if all
Development Funds have been expended, receive reimbursement from Genentech, for
any non-cancelable obligations it has incurred for which Genentech would
otherwise be obligated to support under the Development Budget(s) if this
Agreement had not been terminated. If manufacturing technology has been
transferred to Genentech by Alkermes other than by reason of a material breach
by Alkermes, then Genentech shall transfer all such technology back to Alkermes,
at Alkermes' expense. If Genentech terminates this Agreement pursuant to this
Section 9.2, all rights granted hereunder by Alkermes to Genentech shall
immediately revert to Alkermes and neither Party shall have any further
obligation to the other hereunder except to the extent otherwise accrued or
provided for under this Agreement. In the event Genentech terminates this
Agreement pursuant to this Section 9.2 prior to payment of the Bonus Milestone
Payment, Genentech shall make the Bonus Milestone Payment on the termination
date.


         9.3 BREACH. Failure by either Party to comply with any of the material
obligations contained in this Agreement shall entitle the other Party (the
"Non-Defaulting Party") to give to the Party (the "Defaulting Party") in default
written notice specifying the nature of the default and requiring it to make
good such default. If such default is not cured within ninety (90) days after
the receipt of such notice, the Non-Defaulting Party shall be entitled, without
prejudice to any of its other rights conferred on it by this Agreement, in
addition to any other remedies available to it by law or in equity, immediately
to terminate this Agreement by giving written notice to the Defaulting Party.
With respect to either party, a default with respect to its obligations in one
country shall not constitute a default with respect to its obligations in any
other country. The termination of this Agreement by Alkermes as a result of
Genentech's breach under this Section 9.3 shall terminate all rights granted to
it hereunder, except that Genentech shall pay the Bonus Milestone Payment. The
right of a Party to terminate this Agreement, as hereinafter provided, shall not
be affected in any way by its waiver or failure to take action with respect to
any previous default. Upon any termination by Genentech under this Section 9.3,
the Parties shall have the rights and obligations set forth in Section 9.7.

         9.4 INSOLVENCY OR BANKRUPTCY. Either Party may, in addition to any
other remedies available to it by law or in equity, terminate this Agreement, by
written notice to the other Party in the event the other Party shall have become
insolvent or bankrupt, or shall have made an assignment for the benefit of its
creditors, or there shall have been appointed a trustee or receiver of the other
Party or for all or a substantial part of its property, or any case or
proceeding shall have been commenced or other action taken by or against the
other Party in bankruptcy or seeking reorganization, liquidation, dissolution,
winding-up, arrangement, composition or readjustment of its debts or any


                                       21

REQUEST. REDACTED MATERIAL IS MARKED WITH "X" AND HAS BEEN FILED SEPARATELY WITH
THE SECURITIES AND EXCHANGE COMMISSION.



other relief under any bankruptcy, insolvency, reorganization or other similar
act or law of any jurisdiction now or hereafter in effect, or there shall have
been issued a warrant of attachment, execution, distraint or similar process
against any substantial part of the property of the other Party, and any such
event shall have continued for sixty (60) days undismissed, unbonded and
undischarged.

         9.5 ACCRUED RIGHTS. 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 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.

         9.6 OWNERSHIP OF CLINICAL DATA. All data produced as a result of
clinical trials conducted under this Agreement shall be owned by Genentech,
except to the extent in conflict with the requirements of any regulatory agency
from which the Parties have received, will apply to receive or have applied to
receive Regulatory Approval, and such ownership shall survive any expiration or
termination of this Agreement. Genentech shall be named as the applicant in any
regulatory submission to be made hereunder and shall be the holder of all
Regulatory Approvals. Alkermes may use such data for any purpose contemplated by
this Agreement. Such data shall be considered Disclosed Confidential
Information.

         9.7 RIGHTS AND OBLIGATIONS UPON TERMINATION. In the event of
termination by Genentech for a material breach by Alkermes or upon expiration of
this Agreement, if Alkermes was previously manufacturing Licensed Product for
Genentech, Alkermes shall remain responsible for its supply obligations
hereunder until Alkermes has fully transferred and enabled Genentech or its
designee to perform all of Alkermes' supply obligations. Such transfer shall
include making its personnel and other resources reasonably available to
Genentech as necessary to effect an orderly transition of manufacture of
Licensed Product, with the costs of providing such personnel and resources to be
borne by Genentech, in the event of expiration, and by Alkermes, in the event of
termination by Genentech for material breach. Such transfer will take place, at
Genentech's option, at any time after expiration in any of the Major Market
Countries or the United States until expiration in the last country, in the
event of transfer due to expiration. In addition, Genentech shall thereafter
have an exclusive license in all countries after termination by Genentech for a
material breach by Alkermes for which it shall pay a XXXXXXXXXXXXXXXX royalty on
Net Sales if Alkermes had previously completed a Phase I or Phase I/II clinical
trial with respect to such Licensed Product. In the event of a termination by
Genentech for a material breach by Alkermes or upon expiration of this
Agreement, Genentech shall reimburse Alkermes for Development Funds expended
through the date of termination, so long as such funds were spent in


                                       22

THE SECURITIES AND EXCHANGE COMMISSION.



accordance with the 1999/2000 Development Budget or 2001/2002 Development
Budget, as applicable.

         9.8 OPTION TO COMMERCIALIZE. If Genentech terminates this Agreement
pursuant to Section 9.2 or if Genentech does not make the Bonus Milestone
Payment by December 31, 2001, Alkermes will have the option to continue the
development and commercialization of the 1st and 2nd Generation Formulations of
the Licensed Products pursuant to a license and cost plus supply agreement to be
negotiated in good faith by the parties and with commercially reasonable terms.

         9.9 CHANGE OF CONTROL. In the event of a change of control of Alkermes
Parent, Alkermes Parent, its third party acquiror or its successor will have the
rights described in the Discontinuation Agreement between Genentech and Alkermes
Parent dated the date hereof (the "Discontinuation Agreement"). It is
acknowledged that any exercise by Alkermes Parent of its rights under the
Discontinuation agreement shall not in and of itself trigger a termination of
this Agreement.

10.      PATENT RIGHTS

         10.1 SOLE INVENTIONS. The Parties recognize that either Party may
independently and separately make inventions during the course of this Agreement
relating to human growth hormone, delivery systems for human growth hormone,
PLGA encapsulation of proteins or otherwise related to the scope of this
Agreement but not as a result of activities performed pursuant to this
Agreement. Each Party shall retain title to inventions and knowhow, whether or
not patentable, made or owned solely by it or on its behalf which do not arise
out of the activities performed by it or on its behalf under this Agreement
("Sole Knowhow"). In such event, the Party making the invention shall be the
sole owner of that invention and of any patent applications and patents thereon
(including inventor's certificates) and shall be solely responsible for the
filing, prosecution and maintenance of all such patent application and patents.
Except as provided in this Agreement, neither Party shall have any right to use
or license knowhow to which the other Party has sole title.

         10.2 JOINT PATENTS. All inventions conceived or first reduced to
practice as a result of activities performed pursuant to this Agreement shall be
jointly owned by Genentech and Alkermes. In addition, the event that it is
determined, in accordance with applicable law, that both: (i) employees or
agents of Genentech or any other persons obliged to assign such invention to
Genentech, and (ii) employees or agents of Alkermes or any other persons obliged
to assign such invention to Alkermes, are joint inventors of an invention, the
Parties shall jointly own patents, inventor's certificates and applications
therefor covering such invention. With respect to any sole or joint


                                       23
<PAGE>   24
THIS EXHIBIT HAS BEEN REDACTED AND IS THE SUBJECT OF A CONFIDENTIAL TREATMENT
REQUEST. REDACTED MATERIAL IS MARKED WITH "X" AND HAS BEEN FILED SEPARATELY WITH
THE SECURITIES AND EXCHANGE COMMISSION.



inventions arising as a result of activities performed under this Agreement,
Alkermes and Genentech shall require the Alkermes and/or Genentech inventors to
assign all such inventions to Genentech and Alkermes as joint owners; provided
however, that within thirty (30) days of the termination of the Agreement for
any of the reasons provided in Section 9 hereof, Alkermes and Genentech shall
assign all issued and pending United States and foreign patents and applications
covering inventions arising hereunder according to the following: (i) patent
applications or patents naming only Alkermes inventors shall be assigned to
Alkermes, (ii) patent applications or patents naming only Genentech inventors
shall be assigned to Genentech and (iii) patent applications and patents naming
both Alkermes and Genentech inventors shall remain jointly assigned to Alkermes
and Genentech. With respect to any joint invention or jointly owned invention,
Genentech shall prosecute all such patents relating to Genentech Technology and
Alkermes shall prosecute all such patents relating to the Alkermes Technology.
The party having such obligation to prosecute will be referred to herein as the
"Controlling Party". The Controlling Party shall have the right (but not the
obligation) to undertake such filings, prosecutions and maintenance at its sole
expense, provided that: (a) the Controlling Party notifies the non-Controlling
Party within one (1) month after the filing of any patent application by the
Controlling Party and (b) the Controlling Party provides the non-Controlling
Party, a reasonable time prior to taking or failing to take any action that
would substantially affect the scope or validity of rights under any patent
applications or patents (including but not limited to substantially narrowing or
canceling any claim without reserving the right to file a continuing or
divisional application (which shall not be unreasonably delayed), abandoning any
patent or not filing or perfecting the filing of any patent application), with
notice of such proposed action or inaction so that the non-Controlling Party has
a reasonable opportunity to review and assume the prosecution or maintenance
thereof. In the event that the Controlling Party fails to undertake the filing
of a patent application (or continuing or divisional application) within ninety
(90) days of being designated as the Controlling Party with respect to such
patent application, the non-Controlling Party may undertake such filing,
prosecution and maintenance at its sole expense. Notwithstanding the foregoing,
the Parties shall assist each other to the maximum extent reasonable in securing
intellectual property rights resulting from activities conducted hereunder. As
to enforcement of jointly owned patents, including actions against an infringer,
the Parties shall consult with each other in good faith as to the best manner in
which to proceed. The Parties agree as a basic principle that in the case of
such actions against infringers, the expenses incurred and damages awarded shall
be for the account of the Party or Parties which take such actions to the extent
of their financial participation therein.

         10.3 INFRINGEMENT CLAIMS RELATING TO GENENTECH TECHNOLOGY. Genentech
shall defend, at its sole cost and expense, any legal proceedings brought
against it or


                                       24

REQUEST. REDACTED MATERIAL IS MARKED WITH "X" AND HAS BEEN FILED SEPARATELY WITH
THE SECURITIES AND EXCHANGE COMMISSION.



Alkermes claiming that Alkermes' manufacture of any Licensed Product under this
Agreement constitutes an infringement of third party patent rights arising out
of the use of Genentech Knowhow or the practice of Genentech Patents, except to
the extent that any such proceedings shall arise from the gross negligence or
willful misconduct of Alkermes and shall indemnify and hold Alkermes harmless
from any damages or expenses incurred or awarded as the result of any settlement
related thereto agreed to by Genentech or judgment against Alkermes, provided
that Alkermes gives Genentech written notice of any such claim or the
institution of any suit or suits against it within thirty (30) days after
Alkermes has knowledge of any such claim or suit or suits, that Alkermes assist
Genentech, at Genentech's expense, in the investigation of, preparation for and
defense of any such claim or suit or suits, and that Alkermes not compromise or
settle any such claim or suit or suits without Genentech's written consent.
Alkermes' failure to notify Genentech of such claim or suit or suits within
thirty (30) days shall not obviate its right to receive indemnification
hereunder so long as such failure does not materially prejudice the defense of
such claim or suit or suits. Genentech shall promptly notify Alkermes in writing
of the institution of any suit by a third party against Genentech for patent
infringement involving the manufacture, use, sale, distribution or marketing of
Licensed Product arising out of the activities carried out pursuant to this
Agreement.

         10.4 INFRINGEMENT CLAIMS RELATING TO THE ALKERMES TECHNOLOGY. Alkermes
shall defend, at its sole cost and expense, any legal proceedings brought
against it or Genentech claiming that Alkermes' manufacture of any Licensed
Product or Genentech's manufacture, use, sale, distribution or marketing of
Licensed Product hereunder constitutes an infringement of third party patent
rights arising out of the use of Alkermes Knowhow or the practice of Alkermes
Patents, except to the extent that any such proceedings shall arise from the
gross negligence or willful misconduct of Genentech, and shall indemnify and
hold Genentech harmless from any damages or expenses incurred or awarded as the
result of any settlement related thereto agreed to by Alkermes or judgment
against Genentech, provided that Genentech gives Alkermes written notice of any
such claim or the institution of any suit or suits against it within thirty (30)
days after Genentech has knowledge of any such claim or suit or suits, that
Genentech assist Alkermes, at Alkermes' expense, in the investigation of,
preparation for and defense of any such claim or suit or suits, and that
Genentech not compromise or settle any such claim or suit or suits without
Alkermes' written consent. Genentech's failure to notify Alkermes of such claim
or suit or suits within thirty (30) days shall not obviate its right to receive
indemnification hereunder so long as such failure does not materially prejudice
the defense of such claim or suit or suits. Alkermes shall promptly notify
Genentech in writing of the institution of any suit by a third party against
Alkermes for patent infringement involving the manufacture, use, sale,
distribution or marketing of Licensed Product arising out of the activities
carried out pursuant to this Agreement.

         10.5 SURVIVAL. This Section 10 shall survive the termination or
expiration of this Agreement.

11.      INDEMNIFICATION

                  (a) Genentech hereby agrees to save, defend and hold Alkermes
and its agents and employees harmless from and against any and all suits,
claims, actions, demands, liabilities, expenses and/or loss, including
reasonable legal expense and attorneys' fees ("Losses") except for patent claims
handled under Section 10, resulting directly from the marketing, packaging,
testing, labeling, manufacture, use, or sale of Licensed Products in the United
States and the Territory by Genentech, except to the extent such Losses result
from the negligence or willful misconduct of Alkermes.

                  (b) Alkermes hereby agrees to save, defend and hold Genentech
and its agents and employees harmless from and against any and all Losses except
for patent claims handled under Section 10, resulting directly from the
manufacture of Licensed Products by Alkermes, except to the extent such Losses
result from the negligence or willful misconduct of Genentech.

                  (c) In the event that one Party is seeking indemnification
under this Section 11 (the "Indemnified Party"), it shall inform the other Party
(the "Indemnifying Party") of a claim as soon as reasonably practicable after
the Indemnified Party receives notice of the claim, shall permit the
Indemnifying Party to assume direction and control of the defense of the claim
(including the right to settle the claim solely for monetary consideration), and
shall cooperate as requested (at the expense of the Indemnifying Party) in the
defense of the claim.

                  (d) This Section 11 shall survive termination or expiration of
this Agreement.

12.      MISCELLANEOUS PROVISIONS

         12.1 NO PARTNERSHIP. Nothing in this Agreement is intended or shall be
deemed to constitute a partnership, agency, distributorship, 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.

         12.2 ASSIGNMENTS. Neither Party shall assign any of its rights or
obligations hereunder except: (i) as incident to the merger, consolidation,
reorganization or acquisition of stock or assets affecting substantially all of

the assigning Party; (ii) to any wholly-owned subsidiary if the assigning Party
remains liable and responsible for the performance and observance of all of the
subsidiary's duties and obligations hereunder; or (iii) with the consent of the
other Party. This Agreement shall be binding upon the successors and permitted
assigns of the Parties, and the name of a Party appearing herein shall be deemed
to include the names of such Party's successor's and permitted assigns to the
extent necessary to carry out the intent of this Agreement. Any assignment not
in accordance with this Section 12.2 shall be void.

         12.3 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.

         12.4 NO TRADEMARK RIGHTS. Except as otherwise provided herein, no
right, express or implied, is granted by this Agreement to use in any manner the
names "Alkermes" or "Genentech" or any other trade name or trademark of Alkermes
or Genentech in connection with the performance of this Agreement.

         12.5 PUBLIC ANNOUNCEMENTS. Except as may otherwise be required by law
or regulation, neither Party shall make any public announcement concerning this

                            DISCONTINUATION AGREEMENT


         THIS DISCONTINUATION AGREEMENT (the "Agreement") is entered into
effective as of April 4, 1999 (the "Effective Date") between ALKERMES, INC., a
Pennsylvania corporation ("Alkermes Parent"), located at 64 Sidney Street,
Cambridge, Massachusetts 02139 and GENENTECH, INC., a Delaware corporation
("Genentech"), located at 1 DNA Way, South San Francisco, California 94080.

         Alkermes Controlled Therapeutics, Inc., a Pennsylvania corporation and
a wholly owned subsidiary of Alkermes Parent ("Alkermes"), and Genentech have
entered into, on the date hereof, a License Agreement (the "License Agreement")
under which they will further collaborate on the development of formulations of
recombinant human growth hormone for use in human beings using Alkermes'
technology currently known as the ProLease(R) delivery system, consisting of
patents and know-how, that permits PLGA encapsulation of particular molecules
leading to sustained release of such molecules when injected under the skin.

         Genentech and Alkermes Parent have entered into, on the date hereof, a
Stock Purchase Agreement, pursuant to which Genentech agreed to buy and Alkermes
Parent agreed to sell shares of Alkermes Parent's 1999 Redeemable Convertible
Exchangeable Preferred Stock (the "Preferred Stock") to fund their further
collaborative efforts under the License Agreement through the year 2000.

         Genentech and Alkermes Parent desire to enter into this Agreement in
order to provide for the option by Alkermes Parent or its successor in interest
to discontinue the Preferred Stock funding mechanism described above in the
event of a change in control of Alkermes Parent.

         Therefore, Alkermes Parent and Genentech, intending to be legally bound
hereby, agree as follows:

         1.       Any capitalized term used herein and not defined shall have
                  the meaning set forth in the License Agreement.

         2.       So long as the Bonus Milestone Payment has not been paid
                  pursuant to Section 3.1 of the License Agreement, in the event
                  that a third party, who is not an affiliate of Alkermes
                  Parent, acquires greater than 49% of the voting stock of
                  Alkermes Parent, such acquiring third party, Alkermes Parent
                  or its successor may, in its sole discretion, elect to
                  discontinue the Preferred Stock funding mechanism. In such
                  case,

REQUEST. REDACTED MATERIAL IS MARKED WITH "X" AND HAS BEEN FILED SEPARATELY WITH
THE SECURITIES AND EXCHANGE COMMISSION.



                  (a)      Alkermes Parent or its successor shall redeem for
                           cash that amount of the Preferred Stock held by
                           Genentech equal to (i) the difference between the
                           proceeds from the sale of the Preferred Stock to
                           Genentech and (ii) the Development Funds expended by
                           Alkermes to the date of such redemption in accordance
                           with the 1999/2000 Development Budget;

                  (b)      There will not be a termination of the License
                           Agreement by virtue of the discontinuation of the
                           funding mechanism and the termination provisions in
                           Section 9 of the License Agreement shall control;

                  (c)      The Bonus Milestone Payment shall be adjusted to
                           equal the sum of XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
                           XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
                           XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
                           XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
                           XXXXX multiplied by a fraction, the numerator of
                           which is the Development Funds expended by Alkermes
                           as of the payment date and the denominator of which
                           is the proceeds from the sale of the Preferred Stock
                           to Genentech; and

                  (d)      Alkermes Parent shall redeem the remaining Preferred
                           Stock (or Debentures, if issued in exchange for the
                           Preferred Stock) according to its terms, if not
                           earlier converted into Common Stock or Non-Voting
                           Common Stock.

         3.       This Agreement, along with the License Agreement and the terms
                  of the Preferred Stock and the Non-Voting Common Stock in the
                  Second Amended and Restated Articles of Incorporation of
                  Alkermes, Inc., as amended, constitute and contain the entire
                  understanding and agreement of the parties and cancel and
                  supersede any and all prior negotiations, correspondence,
                  understandings and agreements, whether verbal or written,
                  between the parties respecting the subject matter hereof. No
                  waiver, modification or amendment of any provision of this
                  Agreement shall be valid or effective unless made in writing
                  and signed by a duly authorized officer of each of the

opportunities to advise M.I.T. and shall cooperate with M.I.T. in such filing,
prosecution and maintenance.

         M.I.T. shall instruct Patrea Pabst, or another attorney mutually
acceptable to M.I.T., PSRF, and LICENSEE, to copy LICENSEE on all patent

         6.2 Payment of all fees and costs relating to the filing, prosecution
and maintenance of the PATENT RIGHTS shall be the responsibility of LICENSEE,
whether such fees and costs were incurred before or after the EFFECTIVE DATE,
provided however, LICENSEE shall not be responsible for payment of any fees

                                7 - INFRINGEMENT

         7.1 LICENSEE shall inform M.I.T. promptly in writing of any alleged
infringement of the PATENT RIGHTS by a third party and of any available evidence
thereof.

         7.2 In the FIELD OF USE, LICENSEE shall have the right, but shall not
be obligated, to prosecute at its own expense all infringements of the PATENT
RIGHTS and, in furtherance of such right, M.I.T. hereby agrees that LICENSEE may
include M.I.T. as party plaintiff in any such suit, without expense to M.I.T.
The total cost of any such infringement action commenced or defended solely by
LICENSEE shall be borne by LICENSEE, and LICENSEE shall keep any recovery or
damages for past infringement derived therefrom. No settlement, consent judgment
or

other voluntary final disposition of the suit may be entered into without the
consent of M.I.T., which consent shall not unreasonably be withheld. LICENSEE
shall indemnify M.I.T. against any order for costs that may be made against
M.I.T. in such proceedings.

         7.3 If within six (6) months after having been notified of an alleged
infringement, LICENSEE 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 LICENSEE shall notify M.I.T. at any
time prior thereto of its intention not to bring suit against any alleged
infringer for the FIELD OF USE, then, and in those events only, M.I.T. shall
have the right, but shall not be obligated, to prosecute at its own expense any
infringement of the PATENT RIGHTS in the FIELD OF USE, and M.I.T. may, for such
purposes, use the name of LICENSEE as party plaintiff. The total cost of any
such infringement action commenced or defended solely by M.I.T. shall be borne
by M.I.T. and M.I.T. shall keep any recovery or damages for past infringement
derived therefrom.

         7.4 In the event that LICENSEE shall undertake litigation for the
enforcement of the PATENT RIGHTS, or the defense of the PATENT RIGHTS under this
Article 7, LICENSEE may withhold up to XXXXXXXXXXXXX of the payments otherwise
thereafter due M.I.T. under Article 4 hereunder and apply the same toward
reimbursement of up to half or LICENSEE's expenses, including reasonable
attorneys' fees, in connection therewith. Any recovery of damages by LICENSEE
for each such suit shall be applied first in satisfaction of any unreimbursed
expenses and legal fees of LICENSEE relating to such suit, and next toward
reimbursement of M.I.T. for any payments under Article 4 past due or withheld
and applied pursuant to this Article 7. If any M.I.T.

royalties have been withheld pursuant to this clause, the balance remaining from
any such recovery due to M.I.T. shall be calculated by creating a fraction, the
numerator of which is the amount of royalties withheld, and the denominator of
which is the cost of litigation paid by LICENSEE, and multiplying said fraction
by the balance remaining, but in no event shall such sum be less than
XXXXXXXXXXXXXXX of the balance remaining.

         7.5 In the event that (a) LICENSEE undertakes the enforcement and/or
defense of the PATENT RIGHTS by litigation, and (b) LICENSEE demonstrates by
competent proof that an infringer's activity is substantially affecting
LICENSEE's sales, and that LICENSEE's sales of LICENSED PRODUCTS and LICENSED
PROCESSES have declined by at least XXXXX XXXXXXXXXXXXXXX during the period of
infringement, then, for a period not to exceed two years, LICENSEE may withhold
up to XXXXXXXXXXXXXXX of the payments otherwise due M.I.T. under Article 4
hereunder and apply the same toward reimbursement of LICENSEE's expenses,
including reasonable attorney's fees in connection therewith. Any recovery of
damages by LICENSEE for each such suit shall be applied first in satisfaction of
any unreimbursed expenses and legal fees of LICENSEE relating to such suit, and
next toward reimbursement of M.I.T. for payments under article 4 past due or
withheld and applied pursuant to this Article 7. If any M.IT. royalties have
been withheld pursuant to this clause, the balance remaining from any such
recovery due to M.I.T. shall be calculated by creating a fraction, the numerator
of which is the amount of royalties withheld, and the denominator of which is
the cost of litigation paid by LICENSEE, and

multiplying said fraction by the balance remaining, but in no event shall such
sum be less than XXX XXXXXXXXXXXX of the balance remaining.

         7.6 In the event that a declaratory judgment action alleging invalidity
or noninfringement of any of the PATENT RIGHTS shall be brought against
LICENSEE, LICENSEE shall within ten (10) days after the commencement of such
action notify M.I.T. as to whether or not LICENSEE intends to defend such
action. In the event LICENSEE notifies M.I.T. that LICENSEE intends to defend
such action, LICENSEE shall take over the sole defense of the action at its own
expense. In the event LICENSEE notifies M.I.T. that it intends not to defend
such action, or that it intends to discontinue the defense of such action,
M.I.T. at its sole option, shall have the right, within thirty (30) days of such
notice, to intervene and take over the sole defense of the action at its own
expenses subject to Paragraph 7.4.

         7.7 In any infringement suit as either party may institute to enforce
the PATENT RIGHTS pursuant to this Agreement, the other party hereto shall, at
the request and expense 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.

         7.8 LICENSEE shall have the sole right in accordance with the terms and
conditions herein to sublicense any alleged infringer in the FIELD OF USE for
future use of the PATENT RIGHTS. Any fees as part of such a sublicense shall be
treated per Article 4.

ITS TRUSTEES, DIRECTORS, OFFICERS, EMPLOYEES, AND AFFILIATES, AND PSRF AND ITS
TRUSTEES, DIRECTORS, OFFICERS, EMPLOYEES, AND AFFILIATES, MAKE NO
REPRESENTATIONS AND EXTEND NO WARRANTIES OF ANY KIND, EITHER EXPRESS OR IMPLIED,
INCLUDING BUT NOT LIMITED TO WARRANTIES OF MERCHANTABILITY, FITNESS FOR A

SHALL NOT INFRINGE THE PATENT RIGHT'S OF ANY THIRD PARTY.

         8.4 IN NO EVENT SHALL M.I.T., ITS TRUSTEES, DIRECTORS, OFFICERS,
EMPLOYEES AND AFFILIATES, OR PSRF, ITS TRUSTEES, DIRECTORS, OFFICERS, EMPLOYEES

regulations controlling the export of technical data, computer software,
laboratory prototypes and other commodities (including the Arms Export Control
Act, as amended and the United States Department of Commerce Export
Administration Regulations). The transfer of such items may require a license
from the cognizant agency of the United States Government and/or written
assurances by LICENSEE that LICENSEE shall not export data or commodities to
certain foreign countries without prior approval of such agency. M.I.T. neither
represents that a license shall not be required nor that, if required, it shall
be issued.


                              10 - NON-USE OF NAMES

                                 11 - ASSIGNMENT

void; provided, however, LICENSEE may assign this Agreement in connection with
the sale or transfer of all or substantially all of LICENSEE's equity and assets
related to LICENSED PRODUCTS by merger, consolidation or otherwise, so long as
the assignee shall agree in writing to be bound by all the terms and conditions

grounds for termination by M.I.T. under paragraph 13.3.


                             12 - DISPUTE RESOLUTION

         12.1 Except for the right of either party to apply to a court of

patent validity or infringement, which the parties shall be unable to resolve
within sixty (60) days shall be mediated in good faith. The party raising such
dispute shall promptly advise the other party of such claim, dispute or
controversy in a writing which describes in reasonable detail the nature of such
dispute. By not later than five (5) business days after the recipient has

authority to bind such party, and shall additionally have advised the other
party in writing of the name and title of such representative. By not later than
ten (10) business days after the date of such notice of dispute, the party
against whom the dispute shall be raised shall select a mediation firm in the
Boston area and such representatives shall schedule a date with such firm for a
mediation hearing. The parties shall enter into good faith mediation and shall
share the costs equally. If the representatives of the parties have not been
able to resolve the dispute within fifteen (15) business days after such
mediation hearing, then any and all claims, disputes or controversies arising
under, out of, or in connection with this Agreement, including any dispute
relating to patent validity or infringement, shall be resolved by final and
binding arbitration in Boston, Massachusetts under the rules of the American
Arbitration Association, or the Patent Arbitration Rules if applicable, then
obtaining. The arbitrators shall have no power to add to, subtract from or
modify any of the terms or conditions of this Agreement, nor to award punitive
damages. Any award rendered in such arbitration may be enforced by either party
in either the courts of the Commonwealth of Massachusetts or in the United
States District Court for the District of Massachusetts, to whose jurisdiction
for such purposes M.I.T. and LICENSEE each hereby irrevocably consents and
submits.

         12.2 Notwithstanding the foregoing, nothing in this Article shall be
construed to waive any rights or timely performance of any obligations existing
under this Agreement.

shall terminate upon notice by M.I.T.

         13.2 Should LICENSEE fail to make any payment whatsoever due and

(including, but not limited to, breach or default under Paragraph 3.3), other

referred to in this Paragraph 13.3, M.I.T. shall have the right to terminate
this Agreement and the rights, privileges and license granted hereunder
effective on ninety (90) days' notice to LICENSEE. Such termination shall become

                        SUMMARY OF INCENTIVE LOAN PROGRAM


         In recognition of ongoing contributions and service to the Company, the
Compensation Committee of the Board of Directors of Alkermes has established an
Incentive Loan Program for certain of its employees. Alkermes will offer to lend
these employees a fixed amount (the "Loan") which offer will expire, if not
accepted by the employee, within thirty days of the offer. Any employee
accepting the offer (an "employee participant") will be required to sign an
Incentive Loan Note in the form presented by the Company.

         The general terms of the Loan are summarized as follows:

         1.  TERM.  The term will be two years.

         2.  INTEREST RATE. The interest rate will be equal to the prime rate on
             the commencement date of the Loan.

         3.  FORGIVENESS.
             a.     If, on the first anniversary of the Loan,
                    the employee participant remains an employee
                    of Alkermes, then 50% of the outstanding
                    principal balance of the Loan plus accrued
                    interest on such 50% of the principal will
                    be forgiven on the date of such anniversary.
             b.     If, on the second anniversary of the Loan,
                    the employee participant remains an employee
                    of Alkermes, then the remaining principal
                    balance plus all accrued interest will be
                    forgiven on the date of such anniversary.
             c.     In the event of the death or long-term
                    disability (as defined in the long-term
                    disability policy of the Company) of the
                    employee participant or a change in control
                    of Alkermes, the remaining principal balance
                    plus all accrued interest will be forgiven,
                    regardless of the timing of such event.

         4.  PAYMENT. If the employee participant ceases to be
             employed by Alkermes prior to the second anniversary
             of the Loan, then the employee participant must pay
             all of the outstanding principal balance (less any
             amount forgiven) plus all accrued interest thereon
             within 45 days of the employee participant's last day
             of employment at Alkermes.


         The amount of the principal and interest forgiven on the Loan will be
considered ordinary income by the Internal Revenue Service and will be reflected
as such by Alkermes at the time of the forgiveness (i.e., on the first and
second anniversaries of the Loan). Each employee who is considering
participating in this Loan Incentive Program is advised to consult independent
tax advisors with respect to the tax treatment of this Loan.
