FORWARD-LOOKING STATEMENTS
 
  The description of the business of Boston Life Sciences, Inc. ("BLSI" or the
"Company") that follows contains certain forward-looking statements on the
Company's prospects for its pharmaceutical development activities and results
of operations based on current management expectations. For a description of
meaningful factors which could cause future results to differ materially from
such expectations, see "Business--Products under FDA Review", "Business--
Products in Clinical Trials", "Business--Preclinical Development Programs",
"Business--Licensing Agreements", "Business--Patents", "Business--Corporate
Alliances", "Business--Obtaining FDA and Other Governmental Approvals", and
"Other Business Risks" in Part I and "Management's Discussion and Analysis of
Financial Condition and Results of Operations" in Part II of this Annual
Report on Form 10-K for the fiscal year ended December 31, 1997.
 
OVERVIEW
 
  BLSI is a development stage biotechnology company engaged in the research
and development of novel therapeutic and diagnostic products to treat chronic
debilitating diseases such as cancer, central nervous system (CNS) disorders
and autoimmune diseases. The Company was incorporated in Delaware in 1972
under the name Greenwich Pharmaceuticals Incorporated ("Greenwich"). Effective
June 15, 1995, Greenwich merged with a privately-held company named Boston
Life Sciences, Inc. (the "Merger"). Greenwich survived the Merger and changed
its name to Boston Life Sciences, Inc. On June 6, 1997, the Company's
stockholders approved a one-for-ten reverse split of the common stock
effective as of June 9, 1997. The Company's principal executive offices are
located at 31 Newbury Street, Suite 300, Boston, Massachusetts, and its
telephone number is (617) 425-0200.
 
  In general, the Company's corporate strategy is to seek to (i) fund the
early development of its compounds in preclinical development and (ii) enter
into corporate partnering arrangements with established pharmaceutical or
biotechnology companies to support the continued development of its compounds
and the marketing of any products as and to the extent they receive government
approval. Additionally, since the Company does not currently own any
laboratory or manufacturing facilities, it contracts for such services and
intends to continue to do so.
 
  The Company currently is developing six technologies in its product
portfolio. Therafectin, a potential treatment for rheumatoid arthritis, was
acquired as a result of the Merger. The balance of the Company's technologies
currently under development were invented or discovered by researchers working
at Harvard University and its affiliated hospitals ("Harvard and its
Affiliates") and have been licensed to BLSI.
 
PRODUCTS UNDER FDA REVIEW
 
 1. Therafectin (R) (AMIPRILOSE HCL)
 
  Therafectin is a synthetic molecule developed for the treatment of
Rheumatoid Arthritis which affects approximately 2.5 million individuals in
the U.S. It has been estimated that the total U.S. market for Rheumatoid
Arthritis drug sales is approximately $2.0 billion per year. Therafectin has
undergone extensive preclinical and clinical testing in which the molecule has
been demonstrated to be safe and well-tolerated. A New Drug Application
("NDA") was initially filed with the Food and Drug Administration ("FDA") in
1993 by Greenwich.
 
  The Company's latest 20 week, double-blind, placebo-controlled Phase III
trial included approximately 220 patients, and was conducted at 25 centers
across the United States. The trial was designed to closely resemble
Greenwich's 200 patient Phase III RA-9 trial which demonstrated with
statistical significance that Therafectin was more effective than placebo. The
trial was completed in August 1997, and on September 30, 1997, the Company
announced preliminary results. The primary efficacy variable (similar to the
Greenwich RA-9 trial)
 
                                       1
<PAGE>
 
was "Therapeutic Success", defined as a return to baseline or better in the
number of painful joints, swollen joints, and global assessments at the final
visit. The secondary efficacy variables were the number of painful joints, the
number of swollen joints, the patient's global assessment, and the physician's
global assessment (among others). The results were analyzed on an Intent to
Treat (ITT), Last Observation Brought Forward (LOBF) basis.
 
  The preliminary analysis of the results did not demonstrate a statistically
significant difference between Therafectin and placebo in the percentage of
patients achieving "Therapeutic Success". These results indicated that 40% of
patients receiving Therafectin and 33% of patients receiving placebo achieved
"Therapeutic Success". However, in centers that enrolled at least ten patients
(about half of the patient population), 48% of Therafectin patients achieved
"Therapeutic Success" as compared to 29% of placebo patients. Further, among
the secondary efficacy variables, the improvement in the number of swollen
joints in patients receiving Therafectin was highly statistically
significantly better than in those patients receiving placebo (p<0.007).
Further, in a group of patients with higher levels of swollen joints
(approximately half of those completing the trial), there was a statistically
significant difference between Therafectin and placebo in achieving success as
measured by the primary efficacy variable (Therapeutic Success). Additionally,
utilizing the most recent MIRA ("Minocycline in Rheumatoid Arthritis")
criteria for "meaningful improvement", defined as at least a 50% improvement
in joint swelling compared to baseline, Therafectin showed a statistically
significant improvement compared to placebo. Consistent with the previously
established excellent safety profile of Therafectin, there were no significant
adverse events attributable to Therafectin during the course of the study. In
view of the excellent safety profile of Therafectin, and the previous
statistically significant successful trial combined with at least three
supportive trials (previously completed by Greenwich), the Company convened an
advisory panel of clinical rheumatologists to seek input and advice regarding
whether to proceed with the submission of an amendment to the pending NDA
seeking approval for the drug.
 
  In January 1998, the Company announced its intention to seek marketing
approval for Therafectin based upon the cumulative data obtained from the
trial and the input provided by its advisory panel of clinical
rheumatologists. The consensus of the advisory panel was that the cumulative
safety and efficacy data on Therafectin justified its use by clinicians
looking for a safe alternative to other more toxic drugs now being used to
treat Rheumatoid Arthritis. The Company also reported that further analysis of
the trial data strongly suggested the therapeutic efficacy of Therafectin.
Applying the widely-accepted "Paulus" criteria of therapeutic efficacy (at
least a 20% improvement in 4 of 6 measures: joint tenderness scores, joint
swelling scores, physician's and patient's global assessment, erythrocyte
sedimentation rate (ESR), and morning stiffness), there was a highly
statistically significant difference in the percentage of Therafectin patients
meeting the Paulus criteria for therapeutic efficacy as compared to the
percentage of placebo patients meeting the Paulus criteria (p<0.02). Among the
predefined secondary efficacy variables, the reduction in the number of
swollen joints, the ESR results, Functional Class scores, and the CLINHAQ (a
quality of life measurement) were statistically significant in favor of
Therafectin. In addition, after withdrawing non-steroidal medication, clinical
secondary variables returned to baseline or better in the Therafectin group,
while remaining statistically significantly worse than baseline in the placebo
group. Applying the American College of Rheumatology (ACR) "50% improvement"
criteria to the number of swollen joints, 36% of Therafectin patients
experienced at least a 50% decrease in the number of swollen joints compared
to 23% of placebo patients resulting in a statistically significant difference
(p<0.04). Finally, in the subgroup of patients (about half the total number)
entering the study with greater than the median number of swollen joints
(ten), the primary and secondary variables specified in the trial protocol
were statistically significant. The Company believes that statistically
significant improvement in the important clinical variables related to joint
swelling, functional class, and "quality of life" experienced by the
Therafectin patients demonstrates the clinical efficacy of Therafectin.
Because the beneficial effect is most obvious on joint swelling, the Company
believes that the other improvements are secondary to Therafectin's apparent
ability to favorably impact the underlying disease. A scientific manuscript
summarizing the data from the trial has been submitted to a premier peer-
review medical journal for consideration for publication.
 
  The Company believes that the efficacy and safety of Therafectin as
demonstrated in several clinical trials merit FDA approval. The Company plans
to file an amendment to the NDA for Therafectin in the second quarter
 
                                       2

of 1998 and hopes to meet with the FDA's Arthritis Advisory Committee in the
fourth quarter of 1998. The Company expects to receive a decision from the FDA
in late 1998 or early 1999, although there can be no assurance that a decision
will be rendered by such time. If approved, the Company expects to seek to
commence product sales within six months of receiving approval. The Company
also expects that after such approval, the Company would be able to enter into
a marketing, manufacturing, and distribution agreement with an established
pharmaceutical or biotechnology company to support the sale of Therafectin.
Under such an agreement, the Company would receive royalties based upon
product sales. There can be no assurance, however, that the FDA will approve
Therafectin, or if Therafectin is approved, that the Company will be able to
successfully manufacture, market, and distribute Therafectin, or to enter into
a licensing and strategic alliance on acceptable terms.
 
PRODUCTS IN CLINICAL TRIALS
 
 1. Altropane(TM)
 
  Parkinson's Disease is a chronic, irreversible, neurodegenerative disease
generally afflicting those over 50. It is caused by a marked decrease in the
number of dopamine terminals in specific areas of the brain. Inadequate
production of dopamine causes the classic PD symptoms of resting tremor,
muscle retardation, and rigidity. Altropane is a /123/I-based nuclear medicine
imaging agent that the Company believes may be useful in the diagnosis of PD
in its early stages. Since administration of currently available therapies at
an early stage of PD may delay the progression of the disease, early
definitive diagnosis may be of substantial benefit. PD afflicts about 250,000-
500,000 Americans and about 4 million individuals worldwide. The number of
individuals having PD is expected to grow substantially as life expectancy
grows worldwide.
 
  In July 1996, the Company completed a physician-sponsored Phase I/II study
of Altropane. In the Phase I portion of the study, Altropane was administered
to ten healthy normal volunteers in order to determine safety and brain image
quality. The Phase II portion of the study was designed to test Altropane's
ability to detect changes in the number of dopamine transporters in the brain
in nine patients with clinically diagnosed PD. The study was carried out at
the Massachusetts General Hospital ("MGH") under the guidance of Dr. Alan
Fischman, chief of nuclear medicine at the MGH.
 
  The Company believes that the results from this study provided substantial
evidence that Altropane is a safe, accurate, and convenient agent to image the
dopamine transporter system in the brain. Quantitative data from this study
also indicated that the number of dopamine transporters in the affected region
of the brain can be obtained within 90 minutes of injection. The use of
Altropane together with SPECT brain scanning appeared to demonstrate a greater
than 70% loss of dopamine transporters in patients with mild clinical disease
and an even greater loss in patients with more severe disease. In one patient
in whom the diagnosis of PD was in dispute, physicians using Altropane were
able to demonstrate that the patient did not in fact have PD.
 
  Based upon the results of the physician-sponsored Phase I/II study, the
Company filed an IND application in November 1996 seeking permission to
conduct full scale clinical trials of Altropane. In January 1997, the FDA
notified the Company that it could proceed with the trials. The Company
initiated its Phase I clinical trial in the second quarter of 1997 and
completed the Phase I trial in February 1998. The Company expects to commence
Phase II studies in April 1998 and to complete its Phase III trial by the end
of 1998, although there can be no assurance that this timing in fact will be
met.
 
  In June 1997, three separate scientific papers pertaining to the use of
Altropane in the diagnosis of Parkinson's Disease were presented by scientific
collaborators of the Company at the 44th Annual Meeting of the Society of
Nuclear Medicine in San Antonio, Texas. The first two papers presented,
"Clinical Evaluation of Parkinson's Disease by SPECT with I-123 Altropane,"
and "Rapid Detection of Parkinson's Disease by SPECT with Altropane: A
Selective Ligand for Dopamine Transporters," detailed the results of clinical
studies conducted with 15 subjects, seven of whom were healthy volunteers and
eight of whom suffered from Parkinson's Disease. In the healthy volunteers,
the studies demonstrated that Altropane accumulated rapidly and
 
                                       3
<PAGE>
 
selectively in the dopamine transporters in the brain and yielded high quality
images within an hour after injection. In patients suffering from Parkinson's
Disease, the studies showed that the accumulation of Altropane was markedly
reduced which is consistent with a diagnosis of the disease. The results of
these studies provide further evidence that I-123 Altropane is a highly useful
SPECT ligand for imaging dopamine receptors in the human brain. The results of
the studies also indicate that the high selectivity and rapid accumulation of
Altropane in the dopamine transporters appears to allow for the accurate
diagnosis of Parkinson's Disease in less than two hours after injection. The
third paper, "The SPECT Ligand Altropane Effectively Detects Parkinson's
Disease in Human Putamen," detailed scientists' work with Altropane in post
mortem human brains, evidencing its ability to bind to dopamine transporters.
Altropane binding sites were reduced by more than 80 percent in the putamen of
persons who had Parkinson's Disease thereby supporting the Company's belief in
the selectivity of Altropane for the dopamine transporter in the human brain.
 
  In October 1996, the Company acquired the rights to a technetium-based
imaging agent, Technepine, together with supporting technology, also for the
potential diagnosis of PD. The Company believes that such a technetium-based
agent could eventually supplement Altropane in the PD diagnostic market and
thus could potentially represent a "second generation" radioimaging agent for
the diagnosis of PD. Technepine is in the early stages of preclinical
development and substantial additional work needs to be completed prior to the
commencement of human clinical testing.
 
PRECLINICAL DEVELOPMENT PROGRAMS
 
 1. MHC Class II Expression
 
  Autoimmune diseases are characterized by the production of antibodies
directed against the body's own tissues, and the consequent destruction of
those tissues by the body's immune cells. Central to the pathogenesis of these
diseases is the expression of MHC (Major Histocompatibility Complex) class II
DR molecules on the surface of antigen-presenting cells that are found within
the tissues that are attacked in autoimmune disease. The cause of this
expression of the MHC DR molecules is not known but it appears that the
expression of these molecules plays a role in triggering the immune system to
attack these tissues. The Company is seeking to develop a means to
specifically inhibit MHC DR expression. Inhibition of DR expression might
provide a specific treatment for autoimmune diseases, and because of its
specificity, this treatment might be relatively free of side effects.
 
  Currently, the treatment of autoimmune disease consists of administering
nonspecific anti-inflammatory drugs, or in the most severe cases, nonspecific
immunosuppressives. These drugs, particularly steroids and the
immunosuppressives, are dangerous medications. The side effects of steroids
are particularly severe, and consist of bloating, muscle wasting,
osteoporosis, cataract formation, and psychosis. Therefore, there is a great
need for a specific treatment that addresses the underlying pathology in
autoimmune diseases.
 
  In June 1995, the Company entered into a research and development
collaboration agreement (the "Agreement") with the U.K. company, Zeneca
Pharmaceuticals, Inc. ("Zeneca"). Under the terms of the Agreement, which
originally would have expired in June 1997, Zeneca provided funds for a two
year period to support the research and development of this technology. In
addition to providing funding, Zeneca has been screening its molecule
collection, seeking to identify an inhibitor of the Company's transcription
factor. The Agreement enables Zeneca to acquire the product development rights
to the Company's technology. Zeneca requested, and was granted, an extension,
until May 1998, to complete the screening of its molecule collection before
deciding if it will exercise its product development rights. Zeneca has
indicated that it has identified a number of potential inhibitors from its
small molecule collection and expects to further narrow its selection of
potential lead compounds during the second quarter of 1998. If Zeneca elects
to continue product development following completion of screening, the Company
will receive additional milestone payments as well as royalties from the sale
of any products originating from the collaboration. There can be no assurance,
however, that Zeneca will exercise its product development option, or if
Zeneca does exercise its option, that the Company will receive any milestone
or royalty payments, or that any products will result from the collaboration.

 2. Troponin
 
  Troponin is a naturally occurring protein that appears to inhibit new blood
vessel formation. Angiogenesis (new blood vessel formation) plays a key role
in the growth and spread of solid tumors throughout the body because cancerous
tumors require new blood vessels in order to grow and metastasize. The Company
intends to develop Troponin for the treatment of solid tumors and other
diseases of neovascularization, including rheumatoid arthritis and numerous
eye diseases. BLSI's collaborating scientists at The Children's Hospital
Corporation of Boston ("Children's") have successfully purified and cloned
this protein.
 
  In January 1997, the Company reported that Troponin appears to significantly
inhibit tumor growth in mice. In the animal model laboratory experiment, human
prostate tumors were implanted subcutaneously into the backs of mice and
allowed to grow to a uniform size. Half the mice were then treated with
Troponin for 28 days during which time the growth of the tumors were measured.
The other half of the mice served as untreated controls. In the untreated
control mice, tumors continued to grow in a linear fashion, reaching
approximately four times their original volume after 28 days. In contrast,
treated mice exhibited a very significant inhibition in the growth of their
tumors. Furthermore, treated mice demonstrated no significant growth in their
tumors after approximately fourteen days of treatment, while the tumors in the
untreated mice continued to grow at a rapid rate throughout the 28-day period.
Additional experiments were completed in June 1997 with similar results. In
these studies, human breast cancer was implanted into nude mice and
recombinant Troponin was then administered subcutaneously over a 28-day
period. The results again indicated that tumor growth in the treated animals
was significantly inhibited compared to tumor growth in the control mice.
 
  In July 1997, the Company completed studies which also demonstrated
Troponin's effectiveness in animal models of corneal neovascularization. Based
on these results, the Company plans to expand its preclinical development
program to include potential ophthalmic indications for Troponin. The Company
plans to review additional animal models of corneal and retinal
neovascularization to work on clarifying dosing and formulation issues.
 
  The Company has completed a "scale-up" manufacturing process for Troponin
and, as a result, should be able to produce sufficient quantities of material
using the FDA-required "current good manufacturing processes" ("GMP") for
clinical trials of Troponin. The material will also be used for the final
preclinical studies necessary for the filing of an Investigational New Drug
(IND) application with the FDA. The Company's objective is to file an IND in
1998 and to initiate clinical trials as early as possible thereafter. A
scientific paper detailing the discovery of Troponin I as a native, cartilage-
derived, anti-angiogenic factor has been submitted for publication by the
Company's collaborating scientists in a leading peer-review journal.
 
 3. Axogenesis Factor 1 (AF-1)
 
  Axogenesis Factor 1 (AF-1) is a nerve growth factor that the Company
believes promotes axon outgrowth from central nervous system (CNS) cells. This
property is significant, since the zone of partial injury surrounding the
central necrotic zone contains live but damaged nerve cells that have lost
their axons. AF-1 would potentially salvage these partially injured cells,
thereby resulting in some recovery of function. The Company hopes that AF-1
could provide a "regenerative" treatment for stroke, spinal cord injury and
other CNS degenerative diseases. The rationale for pursuing these indications
is that AF-1 acts by promoting growth of nerve cell projections. These
projections are the most sensitive to injury and they regress if the nerve
cell is stressed but still alive. Thus the cells on the periphery of the
injury may still be alive but with axons that have regressed. The Company
expects that AF-1 might promote the regrowth of these axons and presumably
allow them to reestablish physiologic connections with neighboring cells.
 
  The annual incidence of stroke in the U.S. is approximately 500,000 with
more than 3,000,000 stroke survivors currently alive. The incidence of
traumatic brain injury is approximately 50,000 annually. The incidence of
spinal cord injury is approximately 10,000 cases annually. Treatment for these
conditions is presently limited to hemodynamic support, steroids to reduce
inflammation, and, in the case of stroke, the correction of predisposing
hematological abnormalities.
 
                                       5
<PAGE>
 
  Since the discovery of AF-1, the Company's collaborating scientists believe
that they have purified AF-1, and are in the process of sequencing the
molecule.
 
  In October 1997, the Company announced that in initial in vivo experiments,
AF-1 appeared to stimulate regeneration of the optic nerve in mice. In these
experiments, two weeks following surgical transection of the optic nerve, the
eyes were dissected and examined for optic nerve regeneration. In the group
treated with AF-1, all eyes showed evidence of optic nerve axon regeneration,
whereas in the control group, none of the eyes showed evidence of optic nerve
regeneration. These results, though preliminary, represent an extremely
important "Proof of Principle" milestone in confirming the potential of AF-1
to promote in vivo regeneration in the CNS. The Company believes that this is
the first time that a single, naturally-occurring nerve growth factor has been
reported to regenerate CNS axons in an animal model of CNS injury.
 
  In December 1997, the Company announced that its collaborating scientists
had discovered a second axonal growth factor in connection with its nerve
regeneration program. The Company believes that the discovery of this
naturally occuring molecule provides further evidence that neurons in the
central nervous system may be capable of regenerating axonal connections
between cells.
 
 4. C-MAF
 
  In June 1996, the Company acquired the rights to a transcription factor
called C-MAF which has been shown, in preclinical in vitro tests, to regulate
the switching of T helper 1 (Th1) cells into T helper 2 (Th2) cells. The
Company believes that the ability to switch Th1 cells into Th2 cells (and vice
versa) may be significant in the treatment of autoimmune diseases and
allergies.
 
  The discovery of and potential role for this factor was the subject of a
lead article in the June 28, 1996 edition of Cell. When C-MAF was inserted
into Th1 cells, they transformed themselves into Th2 cells. The Company's
collaborating scientists have since accomplished the stable transfection of a
large proportion of T cells in culture, which is the first step in creating a
gene therapy product for clinical use. In a "Proof of Principle" experiment,
C-MAF was inserted into a fertilized mouse egg. The T cells of the fully
developed animal all appeared to be of the Th2 subtype, thereby providing
evidence that one can transform an animal's T cells in vivo. Animal
experiments are currently underway in an attempt to demonstrate that
autoimmune disease might be successfully treated using this approach. In
addition, the Company's scientists believe that they have identified the C-MAF
promoter, which could represent an ideal target for the development for small
molecule inhibition of the allergic/autoimmune response. A product based upon
a successful program in this area would potentially address a large cross-
section of autoimmune and allergic diseases.
 
  In addition to C-MAF, a second factor, called NIP-45, has been discovered
which appears to synergize with C-MAF and other factors to significantly boost
transcription of the IL4 gene in Th2 cells. Thus, a gene therapy strategy
focused on either inserting C-MAF alone, or C-MAF together with NIP-45, could
potentially yield a powerful therapeutic product for the treatment of severe
autoimmune diseases, although results to date are preliminary.
 
  The approach to the treatment for allergies requires the development of an
inhibitor to C-MAF, NIP-45, or both, in order to decrease the number of Th2
cells and to restore the proper balance between the numbers of Th1 and Th2
cells at the site of inflammation. In the case of asthma and hay fever, the
optimal formulation would be a small molecule that could be delivered via
aerosol to the lung where it would be incorporated into the Th2 cells
surrounding the bronchi. The Company expects to identify and collaborate with
a corporate partner in the development of such a small molecule inhibitor,
although there can be no assurances in that regard.
 
COLLABORATIVE RESEARCH AGREEMENTS
 
  Most of the Company's technologies currently under development were invented
or discovered by researchers working at Harvard and its Affiliates. With
respect to all of its technologies, the Company has funded the research and
development of these technologies through a variety of sponsored research and
licensing
 
                                       6
<PAGE>
 
agreements with the collaborating institution. The Company anticipates that,
to the extent funds are available, it will continue to fund its research and
development work in this manner by entering into sponsored research
agreements, licensing agreements, and contracts with certain contract research
organizations.
 
  Each of the Company's collaborative research agreements is managed by a
sponsoring scientist and/or researcher who has his or her own independent
affiliation with the collaborating institution, primarily Harvard and its
Affiliates. In addition, the Company may enter into consulting, advisory, and
related arrangements with other scientific, research and development
professionals whom the Company believes can assist the Company in the
development of its technologies. A summary of the principal scientific,
research and development professionals associated with the Company, and a
composite of their professional background and affiliations is as follows:
 
  LARRY I. BENOWITZ, PH.D., Director, Laboratories for Neuroscience Research
in Neurosurgery, Children's Hospital, Boston; Associate Professor of
Neuroscience, Department of Surgery, Harvard Medical School
 
  ALAN J. FISCHMAN, M.D., PH.D., Chief, Department of Nuclear Medicine,
Massachusetts General Hospital; Professor of Radiology, Harvard Medical School
 
  LAURIE H. GLIMCHER, M.D., Irene Heinz Given Professor of Immunology, Harvard
School of Public Health; Professor of Medicine, Harvard Medical School
 
  ALEXANDER M. KLIBANOV, PH.D., Professor of Chemistry, Massachusetts
Institute of Technology
 
  ROBERT S. LANGER, SC.D. Germeshausen Professor of Chemical and Biomedical
Engineering, Massachusetts Institute of Technology
 
  BERTHA K. MADRAS, PH.D., Associate Professor of Psychobiology, Harvard
Medical School
 
  PETER MELTZER, PH.D., President, Organix, Inc., Woburn, MA
 
  VLADIMIR TORCHILIN, PH.D., Head of the Chemistry Program, Center for Imaging
and Pharmaceutical Research and Associate Professor of Radiology, Harvard
Medical School
 
LICENSING AGREEMENTS
 
  The Company has entered into a number of exclusive worldwide licenses of
patent applications covering the technologies currently under development.
These licenses are secured through the collaborating institutions where such
technologies were invented or discovered (generally Harvard and its
Affiliates), and generally include the right to sublicense, to make, use or
sell, products or processes resulting from the development of these
technologies. The licensing agreements generally require the payment of an
initial licensing fee as well as additional payments upon the attainment of
development milestones, as defined in each respective agreement. The licensing
agreements also provide for the payment of a royalty to the collaborating
institution based upon the sales of any resulting products by the Company or
its sublicensees. The Company also usually has a first option to license
additional technologies invented or discovered during the course of related
research programs funded by the Company. There can be no assurance that such
research will lead to the discovery of new technologies or that the Company
will be able to obtain a license with respect to such newly discovered
technologies on acceptable terms, if at all.
 
PATENTS
 
  The Company's patent strategy has been to aggressively pursue patent
protection for compounds and technologies in the development pipeline. The
ultimate goal has been to obtain broad patent protection for the compounds and
technologies under development and the relating medical indications of those
technologies. BLSI has also aggressively pursued similar international patent
protection to the extent available for certain compounds
 
                                       7
<PAGE>
 
and technologies, and has filed patent applications covering these compounds
and technologies in most major industrialized countries.
 
  There can be no assurance that patent applications owned by, or licensed to,
the Company will be issued or that, if issued, the Company's patents will be
valid or that they will provide the Company with meaningful protection against
competitors or with a competitive advantage. There can be no assurance that
the Company will not need to acquire licenses under patents belonging to
others for technology potentially useful or necessary to the Company and there
can be no assurance that such licenses will be available to the Company on
acceptable terms, if at all. Moreover, there can be no assurance that any
patent issued to or licensed by the Company will not be infringed upon or
circumvented by others. In particular, if the Company is unable to obtain
issuance of a patent with broad claims, a competitor may be able to design an
alternative treatment that is covered by valid patent claims.
 
  Much of the Company's know-how and technology may not be patentable. To
protect its rights, the Company requires employees, consultants, advisors and
collaborators to enter into confidentiality agreements. There can be no
assurance, however, that these agreements will provide meaningful protection
for the Company's trade secrets, know-how or other proprietary information in
the event of any unauthorized use or disclosure. In addition, the Company's
business may be adversely affected by competitors who independently develop
competing technologies, especially if the Company obtains no, or only narrow,
patent protection.
 
CORPORATE ALLIANCES
 
  In June 1995, the Company entered into a research and development
collaboration agreement (the "Agreement") with the U.K. company, Zeneca
Pharmaceuticals, Inc. ("Zeneca"). Under the terms of the Agreement, which
originally would have expired in June 1997, Zeneca provided funds for a two
year period to support the research and development of this technology. In
addition to providing funding, Zeneca has been screening its molecule
collection, seeking to identify an inhibitor of the Company's transcription
factor. The Agreement enables Zeneca to acquire the product development rights
to the Company's technology. Zeneca requested, and was granted, until May
1998, an extension to complete the screening of its molecule collection before
deciding if it will exercise its product development rights. Zeneca has
indicated that it has identified a number of potential inhibitors from its
small molecule collection and expects to further narrow its selection of
potential lead compounds during the second quarter of 1998. If Zeneca elects
to continue product development following completion of screening, the Company
will receive additional milestone payments as well as royalties from the sale
of any products originating from the collaboration. There can be no assurance,
however, that Zeneca will exercise its product development option, or if
Zeneca does exercise its option, that the Company will receive any milestone
or royalty payments, or that any products will result from the collaboration.
 
SCIENTIFIC ADVISORY BOARD
 
  BLSI has organized a Scientific Advisory Board, which currently consists of
five members (the "Scientific Advisors"). The Scientific Advisors have
extensive experience in fields related to BLSI's fields of research. The
Scientific Advisors may be asked to review and evaluate the research programs
of the Company, to provide advice with respect to technical matters in fields
in which it is involved, and to recommend personnel to the Company.
 
  The Scientific Advisors are employed by or have consulting agreements with
other entities, some of which may conflict or compete with the Company, and
the Scientific Advisors are expected to devote only a minor portion of their
time to the Company. With the exception of the members of the Scientific
Advisory Board who are also consultants to the Company or its subsidiaries,
the Scientific Advisors are not expected to participate actively in the
Company's activities or in the development of its technologies. Certain of the
institutions with which the Scientific Advisors are affiliated may have
regulations or policies which limit the ability of such personnel to act as
consultants or in other capacities for a commercial enterprise. Regulations or
policies not in effect and adopted in the future might limit the ability of
the Scientific Advisors to consult with the Company.
 
                                       8
<PAGE>
 
  Furthermore, no inventions or processes discovered by the Scientific
Advisors will become the property of BLSI but will remain the property of such
persons' full-time employers, other than those inventions or processes that
may be covered by consulting agreements between the Company and such advisors.
In addition, the institutions with which the Scientific Advisors are
affiliated may make available the research services of their scientific and
other skilled personnel, including the Scientific Advisors, to entities other
than the Company pursuant to sponsored research agreements with others. Under
such sponsored research agreements, such institutions may be obligated to
assign or license patents and other proprietary information which may result
from research sponsored by an entity other than BLSI, including research
performed by a Scientific Advisor for a competitor of the Company.
 
  The members of the Scientific Advisory Board and a composite of their
professional background and affiliations is as follows:
 
  HENRY BREM, M.D. Dr. Brem is Professor of Neurosurgery, Ophthalmology, and
Oncology at Johns Hopkins University, and Director of Neurosurgical Oncology
at Johns Hopkins Hospital.
 
  JOSEPH P. VACANTI, M.D. Dr. Vacanti is Associate Professor of Surgery,
Harvard Medical School, and Director of the Laboratory for Transplantation and
Tissue Engineering at the Children's Hospital, Boston.
 
  ALEXANDER M. KLIBANOV, PH.D. Dr. Klibanov is Professor of Chemistry at
Massachusetts Institute of Technology.
 
  MICHAEL A. MOSKOWITZ, M.D. Dr. Moskowitz is Professor of Neurology, Harvard
Medical School, and Associate Neurologist at Massachusetts General Hospital.
 
  VLADIMIR TORCHILIN, PH.D. Dr. Torchilin is the Head of the Chemistry Program
at the Center for Imaging and Pharmaceutical Research, and Associate Professor
of Radiology at the Harvard Medical School.
 
MANUFACTURING
 
  The Company currently has no manufacturing facilities for either clinical
trial or commercial quantities of any of its products. To date, the Company
has obtained the limited amount of quantities required for clinical trials
from contract manufacturing companies. The Company intends to continue to
utilize contract manufacturing arrangements with experienced firms for the
supply of material for both clinical trials and commercial sale. As a result
of these contract manufacturing arrangements, the Company will depend upon
third parties to produce and deliver products in accordance with all
applicable FDA and other governmental regulations. There can be no assurance
that such parties will perform their obligations in a timely fashion and that
any failures by such third parties would not cause a delay in clinical trials,
commercialization of products, or the ability to supply the market.
 
OBTAINING FDA AND OTHER GOVERNMENTAL APPROVALS
 
  The Company's products and its manufacturing and research activities are and
will be subject to varying degrees of regulation by a number of government
authorities in the United States and other countries, including the FDA
pursuant to the Federal Food, Drug and Cosmetic Act. The FDA regulates
pharmaceutical products, including their manufacture and labeling. Prior to
marketing, any product developed by the Company must undergo an extensive
regulatory approval process which includes preclinical and clinical testing of
such product to demonstrate its safety and efficacy. This regulatory process
can require many years and the expenditure of substantial resources. Data
obtained from preclinical and clinical trials are subject to varying
interpretations, which can delay, limit or prevent FDA approval.
 
  None of the Company's product candidates, preclinical compounds or other
technologies have been approved for marketing by the FDA or its international
equivalent. The Company cannot predict all relevant regulatory requirements or
issues that may arise with respect to its current and future products. Changes
in
 
                                       9
<PAGE>
 
existing laws, regulations, policies or interpretations of prior events could
prevent the Company or its licensees, licensors or collaborators from, or
could affect the timing of, achieving compliance with regulatory requirements
including obtaining current and future regulatory clearances, where necessary.
Federal and state laws, regulations and policies are subject to change with
possible retroactive effect, and depend heavily on administrative policies and
interpretations. There can be no assurance that any changes with respect to
Federal and state laws, regulations and policies, and particularly, with
respect to FDA and other such regulatory bodies, will not have a material
adverse effect on the Company.
 
  The process of obtaining FDA clearances can be time-consuming and expensive,
and there is no assurance that such clearances will be granted or that the FDA
review process will not involve delays that materially and adversely affect
the testing, marketing and sale of the Company's products. Similar delays may
be encountered in foreign countries. Moreover, regulatory clearances for new
products, even if granted, may include significant limitations on the uses for
which such products may be marketed. In addition, even if regulatory approval
is obtained, any marketed product and its manufacturer are subject to
continual review and any discovery of previously unrecognized problems with a
product or manufacturer could result in the suspension or limitation of
approvals. There can be no assurance that any clearances that are required,
once obtained, will not be withdrawn or that compliance with other regulatory
requirements can be maintained to the degree that the Company may have already
complied.
 
COMPETITION
 
  The pharmaceutical industry is highly competitive and research on the causes
of, and possible treatments for, rheumatoid arthritis, cancer, Parkinson's
Disease, central nervous system disorders and autoimmune diseases are
developing rapidly. The Company competes with a number of pharmaceutical and
biotechnology companies which have financial, technical and marketing
resources significantly greater than those of the Company. Some companies with
established positions in the pharmaceutical industry may be better equipped
than the Company to develop and market products based on the application of
new technologies for the treatment of these diseases. A significant amount of
research in the field is also being carried out at universities and other not-
for-profit research organizations. These institutions are becoming
increasingly aware of the commercial value of their findings and are becoming
more active in seeking patent protection and licensing arrangements to collect
royalties for use of technology that they have developed. These institutions
may also market competitive commercial products on their own or through joint
ventures and may compete with the Company in recruiting highly qualified
scientific personnel.
 
  The Company is pursuing areas of product development in which there is a
potential for extensive technological innovation in relatively short periods
of time. The Company's competitors may succeed in developing products that are
more effective than those of the Company. Rapid technological change or
developments by others may result in the Company's potential products becoming
obsolete or non-competitive.
 
ADDITIONAL BUSINESS RISKS
 
 Early Stage of Development; History of Operating Losses; Anticipation of
Future Losses
 
  The Company is a development stage company. It has generated no revenues
from product sales, and it does not expect to generate revenue from product
sales. As of December 31, 1997, the Company's accumulated deficit was
approximately $33 million. To date, the Company has dedicated most of its
financial resources to the research and development of products, general and
administrative expenses, and the prosecution of patents and patent
applications. The Company expects to incur significant operating losses for at
least the next twelve months, and possibly longer, primarily due to the
expansion of its research and development programs, including preclinical
studies and clinical trials, and costs associated with the commercialization
of its products, if regulatory approvals are received. The Company's ability
to achieve profitability will depend, among other things, on successfully
completing development of its products, obtaining regulatory approvals,
establishing manufacturing, sales and marketing capabilities or collaborative
arrangements, and raising sufficient funds to finance its
 
                                      10
<PAGE>
 
activities. There can be no assurance that the Company will be able to achieve
profitability or that profitability, if achieved, can be sustained. See
"Selected Financial Data" and "Management's Discussion and Analysis of
Financial Condition and Results of Operations."
 
 Future Capital Needs; Uncertainty of Additional Funding
 
  The Company has experienced negative cash flows from operations since its
inception and has funded its activities to date primarily from equity
financings. The Company has expended, and will continue to require,
substantial funds to continue research and development, including preclinical
studies and clinical trials of its products, and to commence sales and
marketing efforts if FDA and other regulatory approvals are obtained. The
Company expects that its existing capital resources will be sufficient to fund
its capital requirements through at least the next twelve months, and possibly
longer. Thereafter, the Company may need to raise substantial additional
capital to fund its operations. The Company's capital requirements will depend
on many factors, including the problems, delays, expenses and complications
frequently encountered by development stage companies; the progress of the
Company's research, development and clinical trial programs; the Company's
ability to satisfy the extent and terms of any future collaborative research,
manufacturing, marketing or other funding arrangements; the costs and timing
of seeking regulatory approvals of the Company's products; the Company's
ability to obtain regulatory approvals; the success of the Company's sales and
marketing programs; costs of filing, prosecuting and defending and enforcing
any patent claims and other intellectual property rights; and changes in
economic, regulatory or competitive conditions of the Company's planned
business. Estimates about the adequacy of funding for the Company's activities
are based on certain assumptions, including the assumption that testing and
regulatory procedures relating to the Company's products can be conducted at
projected costs. There can be no assurance that changes in the Company's
research and development plans, acquisitions, or other events will not result
in accelerated or unexpected expenditures. To satisfy its capital
requirements, the Company may seek to raise additional funds in the public or
private capital markets. The Company's ability to raise additional funds in
the public or private markets will be adversely affected if the results of its
current or future clinical trials are not favorable. The Company may seek
additional funding through corporate collaborations and other financing
vehicles. There can be no assurance that any such funding will be available to
the Company on favorable terms, if at all. If adequate funds are not
available, the Company may be required to significantly curtail one or more of
its research or development programs, or it may be required to obtain funds
through arrangements with future collaborative partners or others that may
require the Company to relinquish rights to some or all of its technologies or
products. If the Company is successful in obtaining additional financing, the
terms of such financing may have the effect of diluting or adversely affecting
the holdings or the rights of the holders of the Company's Common Stock. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations--Liquidity and Capital Resources."
 
 Potential Product Liability; Availability of Insurance
 
  The Company risks exposure to product liability claims if the use of its
products is alleged to have an adverse effect on subjects or patients. This
risk exists for products tested in human clinical trials as well as products
that are sold commercially. There can be no assurance that product liability
claims, if made, would not result in a recall of the Company's products or a
change in the indications for which they may be used. The Company maintains
product liability insurance coverage for claims arising from the use of its
products in clinical trials. There can be no assurance that this coverage will
be adequate to cover claims. Product liability insurance is becoming
increasingly expensive, and no assurance can be given that the Company will be
able to maintain such insurance, obtain additional insurance, or obtain
insurance at a reasonable cost or in sufficient amounts to protect the Company
against losses that could have a material adverse effect on the Company.
 
 Dependence on Key Personnel
 
  The success of the Company depends in large part on the Company's ability to
attract and retain highly qualified scientific and management personnel. The
Company faces competition for such personnel from other companies, research
and academic institutions, government entities and other organizations. There
can be no assurance that the Company will be successful in hiring or retaining
key personnel.
 
                                      11
<PAGE>
 
 Year 2000 Compliance
 
  The Company does not use computers extensively in its operations. To the
extent that the Company uses software applications which contain source code
that is unable to interpret appropriately the upcoming calendar year "2000",
some level of modification or, more likely, the replacement of such
applications will be necessary. The Company is currently in the process of
completing the identification of software applications that are not "Year
2000" compliant and expects to make appropriate responses to address any issue
identified. Given the information known at this time about the Company's
systems, coupled with the Company's ongoing, normal course-of-business efforts
to upgrade or replace business critical systems as necessary, it is currently
not anticipated that these "Year 2000" costs will have any material adverse
effect on the Company's business, financial condition or results of
operations.
 
EMPLOYEES
 
  As of March 24, 1998, the Company employed 12 individuals full-time, of whom
four hold Ph.D. or M.D. degrees. None of the Company's employees is covered by
a collective bargaining agreement. The Company believes its employee relations
are good.
 
ITEM 2. PROPERTIES.
 
  The Company's administrative offices are located in Boston, Massachusetts.
The lease on this 3,500 square foot facility expires on June 30, 1999 and can
be renewed by the Company for additional three year periods. In addition, the
Company has 4,000 square feet of warehouse space in Horsham, Pennsylvania.
This lease will terminate on March 31, 1999. The Company believes that its
existing facilities are adequate for its present and anticipated purposes,
except that additional facilities will be needed if the Company builds its own
laboratory space or undertakes manufacturing operations. The Company, however,
has no present intention to develop such capabilities for its technologies.
 
ITEM 3. LEGAL PROCEEDINGS.
 
  The Company is not a party to any legal proceedings and is not aware of any
threatened litigation that could have a material adverse effect on the
Company's business, results of operations or financial position.
 
ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS.
 
  Not applicable.
 
                     EXECUTIVE OFFICERS OF THE REGISTRANT.
 
  The following is a list of the executive officers of the Company and their
principal positions with the Company. Except for S. David Hillson, Esq. and

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS.
 
  The Management's Discussion and Analysis of Financial Condition and Results
of Operations that follows contains forward looking statements based on
current management expectations. Meaningful factors which could cause future
results to differ materially from such expectations include, without
limitation, the following: (i) the results from the Phase II/III clinical
trials for Altropane, (ii) scientific data collected on the Company's
technologies currently in preclinical research and development, (iii)
decisions made by the Food and Drug Administration ("FDA") or other regulatory
bodies with respect to the initiation of human clinical trials, (iv) decisions
made by the FDA or other regulatory bodies with respect to approval of the
amendment to the NDA for Therafectin, and to the commercial sale of any of the
Company's proposed products, including Therafectin, (v) the commercial
acceptance of any products approved for sale and the ability of the Company to
manufacture, distribute and sell for a profit any products approved for sale,
(vi) the Company's ability to obtain the necessary patents and proprietary
rights to effectively protect its proposed products and technologies, and
(vii) the outcome of any collaborations or alliances currently entered into by
the Company or to be entered into by the Company in the future with
pharmaceutical or other biotechnology companies.
 
RESULTS OF OPERATIONS
 
 Overview
 
  On June 15, 1995, Greenwich Pharmaceuticals Incorporated ("Greenwich")
acquired all of the outstanding common stock of Boston Life Sciences, Inc.
("Old BLSI") and merged with and into Old BLSI. Effective June 15, 1995, the
merged company was renamed "Boston Life Sciences, Inc." (the "Company") and
the management and Board of Directors of Old BLSI assumed management of the
Company. The acquisition of Old
 
                                      15
<PAGE>
 
BLSI by Greenwich has been treated as a recapitalization of Old BLSI with Old
BLSI as the acquiror (reverse acquisition). The historical financial
statements prior to June 15, 1995 are those of Old BLSI.
 
  The Company is a biotechnology company engaged in the research and
development of novel therapeutic and diagnostic products to treat chronic
debilitating diseases such as rheumatoid arthritis, cancer, central nervous
system disorders and autoimmune diseases. The Company anticipates that its (i)
research and development and (ii) general and administrative costs will
continue to increase as the Company attempts to gain regulatory approval for
the commercial introduction of its proposed products. At December 31, 1997,
the Company is considered a development stage enterprise as defined in
Statement of Financial Accounting Standards No. 7.
 
 Year Ended December 31, 1997 and 1996
 
  The Company's net loss was $7,974,016 for the year ended December 31, 1997
as compared with $5,996,147, excluding preferred stock preferences of
$34,387,953, for the year ended December 31, 1996. Net loss per common share
totaled $.64 per share for 1997 as compared with $.61 per share, excluding the
effect of preferred stock preferences which equaled $3.48 per share, for 1996.
The higher loss in 1997 was primarily due to (i) lower revenues, (ii)
increased research and development expenses, and (iii) higher costs associated
with the completion of the Phase III clinical trial for Therafectin which
began in March 1996 and ended in August 1997. The effect of these items were
partially offset by (i) lower licensing fees, (ii) decreased general and
administrative expenses and (iii) a reduction in interest expense.
 
  The net loss available to common shareholders for the 1996 period, including
preferred stock preferences of $34,387,953, totaled $40,384,100. Net loss per
common share for 1996, including $3.48 attributable to preferred stock
preferences, totaled $4.09. In January and February 1996, the Company
completed a private placement of Series A Convertible Preferred Stock and
warrants. Based on the market price of the Company's stock on the date of
issuance, the preferred stock had a beneficial conversion feature of
$28,389,846 and the warrants had a fair value of $5,998,107.
 
  Revenue was $83,060 during the year ended December 31, 1997 as compared with
$200,000 during the year ended December 31, 1996. Revenue for both periods was
attributable to the Agreement entered into with Zeneca in 1995. Under the
terms of the Agreement, which originally would have expired in June 1997,
Zeneca provided funds to support the research and development of certain
technology. In addition to providing funding, Zeneca has been screening its
molecule collection, seeking to identify an inhibitor of the Company's
transcription factor. The Agreement enables Zeneca to acquire the product
development rights to the Company's technology. Zeneca requested, and was
granted, an extension until May 1998, to complete the screening of its
molecule collection before deciding if it will exercise its product
development rights. If Zeneca exercises its option and achieves certain
product development milestones, the Company will receive additional milestone
payments as well as royalties from the sale of any products originating from
the collaboration.
 
  Research and development expenses were $4,874,233 during the year ended
December 31, 1997 as compared with $2,408,734 during the year ended December
31, 1996. This increase was primarily due to the Company incurring a higher
level of research and development expenses for its existing technologies in
1997 as compared to 1996 related to the continued advancement of its clinical
efforts, and, to a lesser degree, to an increase in the number of personnel
supporting the Company's research and development activities. The majority of
the Company's research and development expenses were, and will continue to be
in 1998, sponsored research obligations paid to Harvard University and its
affiliated hospitals.
 
  Licensing fees were $20,000 during the year ended December 31, 1997 as
compared with $390,000 during the year ended December 31, 1996. The decrease
primarily related to a decrease in the number of new technologies licensed to
the Company in 1997 as compared to 1996, as well as lower costs to obtain such
licenses. During 1997, the Company paid $20,000 to license one new technology
as compared to $340,000 paid in 1996 for the rights to three new technologies.
In addition to an initial licensing fee payment, the Company is obligated to
pay additional amounts upon the attainment of development milestones, as
defined in each respective
 
                                      16
<PAGE>
 
licensing agreement, as well as royalties upon the sales of any resulting
products. During 1996, the Company made a milestone payment of $30,000 related
to the development of one of its technologies. The Company expects to pay
future licensing fees, the timing and amounts of which will depend upon the
progress attained in developing existing technologies and the terms of
agreements which may be executed for technologies currently being developed or
which may be developed in the future. There can be no assurance regarding the
likelihood or materiality of any such future licensing agreements.
 
  Therafectin related expenses were $2,190,040 during the year ended December
31, 1997 as compared with $1,546,791 during the year ended December 31, 1996.
The increased level of expenses in 1997 related to the higher average number
of patients enrolled in the Company's Phase III clinical trial for Therafectin
in 1997 as compared to 1996. The Company commenced its Phase III clinical
trial in March 1996 and completed the trial in August 1997. On September 30,
1997, the Company announced the preliminary results of the trial. An analysis
of the trial data indicated that a statistically significant difference
between Therafectin and placebo in the percentage of patients achieving the
overall composite efficacy index had not been realized. However, in an
important secondary efficacy variable, there was a highly statistically
significant difference between Therafectin and placebo in reducing the number
of swollen joints in patients. Further, in a group of patients with higher
levels of swollen joints (approximately half of those completing the trial),
there was a statistically significant difference between Therafectin and
placebo in achieving success as measured by the overall composite efficacy
index. Additionally, utilizing the most recent MIRA ("Minocycline in
Rheumatoid Arthritis") criteria for "meaningful improvement", defined as at
least a 50% improvement in joint swelling compared to baseline, Therafectin
showed a statistically significant improvement compared to placebo. Consistent
with the previously established excellent safety profile of Therafectin, there
were no significant adverse events attributable to Therafectin during the
course of the study. In view of the excellent safety profile of Therafectin,
and the previous statistically significant successful trial combined with at
least three supportive trials (previously completed by Greenwich), the Company
convened an advisory panel of rheumatologists to seek input and advice
regarding whether to proceed with the submission of an amendment to the
pending NDA seeking approval for the drug.
 
  In January 1998, the Company announced its intention to seek marketing
approval for Therafectin based upon the cumulative data obtained from the
trial and the input provided by its special panel of clinical rheumatologists.
The consensus of this special advisory panel was that the cumulative safety
and efficacy data on Therafectin justified its use by clinicians looking for a
safe alternative to other more toxic drugs now being used to treat Rheumatoid
Arthritis. The Company also reported that further analysis of the trial data
strongly suggested the therapeutic efficacy of Therafectin. Applying the
widely-accepted "Paulus" criteria of therapeutic efficacy (at least a 20%
improvement in 4 of 6 measures: joint tenderness scores, joint swelling
scores, physician's and patient's global assessment, erythrocyte sedimentation
rate (ESR), and morning stiffness), there was a highly statistically
significant difference in the percentage of Therafectin patients meeting the
Paulus criteria for therapeutic efficacy as compared to the percentage of
placebo patients meeting the Paulus criteria (p<0.02). Among the predefined
secondary efficacy variables, the reduction in the number of swollen joints,
the ESR results, Functional Class scores, and the CLINHAQ (a quality of life
measurement) were statistically significant in favor of Therafectin. In
addition, after withdrawing non-steroidal medication, clinical secondary
variables returned to baseline or better in the Therafectin group, while
remaining statistically significantly worse than baseline in the placebo
group. Applying the American College of Rheumatology (ACR) "50% improvement"
criteria to the number of swollen joints, 36% of Therafectin patients
experienced at least a 50% decrease in the number of swollen joints compared
to 23% of placebo patients resulting in a statistically significant difference
(p<0.04). Finally, in the subgroup of patients (about half the total number)
entering the study with greater than the median number of swollen joints
(ten), the primary and secondary variables specified in the trial protocol
were statistically significant. The Company believes that statistically
significant improvement in the important clinical variables related to joint
swelling, functional class, and "quality of life" experienced by the
Therafectin patients demonstrates the clinical efficacy of Therafectin.
Because the beneficial effect is most obvious on joint swelling, the Company
believes that the other improvements are secondary to Therafectin's apparent
ability to favorably impact the underlying disease.

  Before any commercially viable product from Therafectin may be developed,
and any revenue generated therefrom, the Company currently expects that
between $1.0 million and $2.0 million of additional future expense will be
necessary. There can be no assurance, however, that the expenditure of these
additional amounts will result in the regulatory approval of any compounds or
that such approval will ever be able to be obtained by the Company. Moreover,
if the Company is ultimately unsuccessful in obtaining regulatory approval for
Therafectin, the Company may be required to write off all or some portion of
the $3.5 million asset value attributable to Therafectin as reflected on the
Company's balance sheet.
 
  General and administrative expenses were $2,118,391 during the year ended
December 31, 1997 as compared with $2,701,874 during the year ended December
31, 1996. This decrease was primarily due to lower professional services
expenses.
 
  Interest income was $1,148,025 during the year ended December 31, 1997 as
compared with interest income of $1,151,810 during the year ended December 31,
1996. Average cash and investment balances during 1997 were comparable to
1996. The interest income realized during both periods related to the Company
raising net proceeds of approximately $25.6 million from two private
placements completed in 1996. Interest expense totaled $2,437 during the year
ended December 31, 1997 as compared to $300,558 during the year ended December
31, 1996. Interest expense incurred in 1996 included amounts related to (i)
$2.175 million of notes payable, which were fully repaid on April 1, 1996,
(ii) $1.0 million of convertible debentures, which were converted to common
stock in the first quarter of 1996, and (iii) the amortization of the discount
and debt issuance costs on both debt instruments during the period outstanding
in 1996.
 
  At December 31, 1997, the Company had net deferred tax assets of
approximately $19.5 million for which a full valuation allowance has been
established. As a result of its concentrated efforts on research and
development and Therafectin related expenses, the Company has a history of
incurring net operating losses and expects to incur additional net operating
losses for the foreseeable future. Accordingly, management believes that, at
the present time, it is appropriate to conclude that it is more likely than
not that the future benefits related to the deferred tax assets will not be
realized and, therefore, has provided a full valuation allowance for these
assets. In the event the Company achieves profitability, these deferred tax
assets may be available to offset future income tax liabilities and expense.
 
 Year Ended December 31, 1996 and 1995
 
  The Company's net loss was $5,996,147, excluding preferred stock preferences
of $34,387,953, for the year ended December 31, 1996 as compared with
$14,149,151 during the year ended December 31, 1995. Net loss per common share
totaled $.61 per share for 1996, excluding the effect of preferred stock
preferences which equaled $3.48 per share, for 1996, as compared with $2.23
per share for 1995. The Company's operating loss for the year ended December
31, 1995 totaled $13,045,382 which included approximately $10.4 million of
purchased research and development in-process which was expensed in
conjunction with the Company's Merger with Greenwich on June 15, 1995.
Exclusive of the purchased research and development in-process, the Company's
operating loss increased from $2,623,838 for the year ended December 31, 1995
to $6,847,399 for the year ended December 31, 1996. The higher operating loss
in 1996 was primarily due to (i) lower revenues, (ii) costs associated with
the preparation and initiation of the Phase III clinical trial for Therafectin
which began in March 1996, (iii) an increase in the number of technologies
licensed to the Company by its collaborative partners and the resulting
incurrence of licensing fees and research and development expenses, and (iv)
higher costs associated with being a publicly traded company during all of
1996 as compared to only a portion of 1995.
 
  The net loss available to common shareholders for the 1996 period, including
preferred stock preferences of $34,387,953, totaled $40,384,100. Net loss per
common share for 1996, including $3.48 attributable to preferred stock
preferences, totaled $4.09. In January and February 1996, the Company
completed a private placement of Series A Convertible Preferred Stock and
warrants. Based on the market price of the Company's stock on the date of
issuance, the preferred stock had a beneficial conversion feature of
$28,389,846 and the warrants had a fair value of $5,998,107.
 
                                      18
<PAGE>
 
  Revenue was $200,000 during the year ended December 31, 1996 as compared
with $416,940 during the year ended December 31, 1995. Revenue for both
periods includes approximately $200,000 and $167,000, respectively,
attributable to the Agreement with Zeneca. Revenue for 1995 also includes the
recognition of $250,000 of revenue which had previously been deferred until
the conclusion of negotiations regarding the treatment of such amounts with a
potential corporate partner.
 
  Research and development expenses were $2,408,734 during the year ended
December 31, 1996 as compared with $1,446,298 during the year ended December
31, 1995. This increase was primarily due to (i) the Company incurring a
higher level of research and development expenses for its existing
technologies in 1996 as compared to 1995 related to the continued advancement
of its clinical efforts, (ii) the initiation of new Company sponsored research
contracts with its collaborators for the development of technologies licensed
to the Company in 1996 by these partners, and (iii) an increase in the number
of personnel supporting the Company's research and development activities. The
majority of the Company's research and development expenses were sponsored
research obligations paid to Harvard University and its affiliated hospitals.
 
  Licensing fees were $390,000 during the year ended December 31, 1996 as
compared with $71,250 during the year ended December 31, 1995. The increase
primarily related to $340,000 of licensing fee payments for three new
technologies licensed to the Company in 1996 as compared to licensing fee
payments of $35,000 for two technologies initially licensed to the Company in
1995. In addition to an initial licensing fee payment, the Company is
obligated to pay additional amounts upon the attainment of development
milestones, as defined in each respective licensing agreement, as well as
royalties upon the sales of any resulting products. During 1996, the Company
made a milestone payment of $30,000 related to the development of one of its
technologies. The Company expects to pay future licensing fees, the timing and
amounts of which will depend upon the progress attained in developing existing
technologies and the terms of agreements which may be executed for
technologies currently being developed or which may be developed in the
future. There can be no assurance regarding the likelihood or materiality of
any such future licensing agreements.
 
  Therafectin related expenses were $1,546,791 during the year ended December
31, 1996 as compared with zero during the comparable 1995 period. The Company
commenced its Phase III clinical trial for Therafectin in March 1996.
 
  General and administrative expenses were $2,701,874 during the year ended
December 31, 1996 as compared with $1,523,230 during the year ended December
31, 1995. This increase was primarily due to the Company (i) expanding its
operations, including its headcount, and (ii) incurring higher costs,
primarily legal, public relations, and other professional services expenses,
associated with being a publicly traded company during all of 1996 as compared
with only a portion of 1995.
 
  Interest income was $1,151,810 during the year ended December 31, 1996 as
compared with interest income of $51,120 during the year ended December 31,
1995. The increase in 1996 related to higher average cash and investment
balances associated with the Company raising net proceeds of approximately
$25.6 million from two private placements completed in 1996. Interest expense
totaled $300,558 during 1996 as compared to $1,154,889 during 1995. Interest
expense incurred in 1995 included amounts related to (i) the issuance of
$2.175 million of notes payable during the first quarter of 1995, (ii) the
issuance of $1.0 million of convertible subordinated debentures in the fourth
quarter of 1995, and (iii) the amortization of the discount and debt issuance
costs associated with both debt instruments. Interest expense incurred in 1996
included amounts related to (i) the notes payable, which were fully repaid on
April 1, 1996, (ii) the convertible debentures, which were converted to common
stock in the first quarter of 1996, and (iii) the amortization of the discount
and debt issuance costs on both debt instruments during the period outstanding
in 1996.
 
  At December 31, 1996, the Company had net deferred tax assets of
approximately $15.6 million for which a full valuation allowance has been
established. As a result of its concentrated efforts on research and
development, and Therafectin related expenses, the Company has a history of
incurring net operating losses and expects to incur additional net operating
losses for the foreseeable future. Accordingly, management believed
 
                                      19
<PAGE>
 
that it was appropriate to conclude that it was more likely than not that the
future benefits related to the deferred tax assets would not be realized and,
therefore, provided a full valuation allowance for these assets. In the event
the Company achieves profitability, these deferred tax assets may be available
to offset future income tax liabilities and expense.

  Since its inception, the Company has primarily satisfied its working capital
requirements from the sale of the Company's securities through private
placements. In January and February 1996, the Company raised approximately
$20.6 million of net proceeds by completing a private placement of units
consisting of (i) shares of its Series A Convertible Preferred Stock and (ii)
warrants to purchase shares of the Company's common stock. In June 1996, the
Company raised approximately $5.0 million of net proceeds by completing a
private placement of 500,000 shares of common stock. For additional
information related to the private placements, see Notes 9 and 10 of the Notes
to the Consolidated Financial Statements included in this Form 10-K.
 
  In addition, the Company has raised working capital through the issuance of
notes payable and convertible debentures. In March 1995, Old BLSI issued
$2,175,000 of units consisting of notes payable, common stock and warrants to
purchase shares of Old BLSI's Series B Preferred Stock. The $2,175,000 of
notes payable became obligations of the Company and the warrants exercisable
for shares of Old BLSI Series B Preferred Stock were exchanged for warrants
exercisable for shares of the Company's common stock. In the second quarter of
1996, the Company repaid all accrued interest plus the remaining principal of
$1,525,000 of the notes payable. In December 1995, the Company also issued
$1,000,000 of convertible subordinated debentures. During the first quarter of
1996, the entire $1,000,000 of convertible subordinated debentures were
converted into 156,605 shares of common stock.
 
  In the future, the Company's working capital and capital requirements will
depend on numerous factors, including the progress of the Company's research
and development activities, the level of resources that the Company devotes to
the developmental, clinical, and regulatory aspects of its products, and the
extent to which the Company enters into collaborative relationships with
pharmaceutical and biotechnology companies.
 
  At December 31, 1997, the Company had available cash, cash equivalents, and
investments of approximately $14.1 million and working capital of
approximately $12.7 million. The Company believes that the level of financial
resources available at December 31, 1997 will provide sufficient working
capital to meet its anticipated expenditures for more than the next twelve
months. The Company may raise additional capital in the future through
collaboration agreements with other pharmaceutical or biotechnology companies,
debt financing and equity offerings. There can be no assurance, however, that
the Company will be successful or that additional funds will be available on
acceptable terms, if at all.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1. THE COMPANY AND ITS SIGNIFICANT ACCOUNTING POLICIES
 
  Boston Life Sciences, Inc. (the "Company"), founded in October 1992, is a
biotechnology company engaged in the research and development of novel
therapeutic and diagnostic products to treat chronic debilitating diseases
such as cancer, central nervous system disorders and autoimmune diseases. On
June 15, 1995, Greenwich Pharmaceutical Incorporated ("Greenwich") acquired
(the "Merger") all of the outstanding capital stock of Boston Life Sciences,
Inc. ("Old BLSI"). Effective June 15, 1995, the merged company was renamed
"Boston Life Sciences, Inc." (the "Company") and the management and Board of
Directors of Old BLSI assumed management of the Company (Note 2).
 
  During the period from inception through December 31, 1997, the Company has
devoted substantially all of its efforts to business planning, raising
financing, consummating the merger with Greenwich, the research and
development of its technologies, Therafectin related activities and corporate
partnering efforts. Accordingly, the Company is considered to be in the
development stage as defined in Statement of Financial Accounting Standards
No. 7.
 
  A summary of the Company's significant accounting policies is as follows:
 
 Basis of Consolidation
 
  The Company's consolidated financial statements include the accounts of its
six subsidiaries where a majority of the operations are conducted. Five of
these subsidiaries, Ara Pharmaceutical, Inc., Acumed Pharmaceutical, Inc.,
Boston Life Sciences International, Inc., Coda Pharmaceutical, Inc. and
NeuroBiologics, Inc., are wholly-owned. A minority shareholder owns 10% of the
sixth subsidiary, Procell Pharmaceutical, Inc. ("Procell"). For the period
from inception (October 16, 1992) through December 31, 1997, each subsidiary
has incurred losses, all of which are included in the Company's consolidated
statement of operations. All significant intercompany transactions and
balances have been eliminated.
 
 Cash, Cash Equivalents and Investments
 
  The Company considers all highly liquid investments purchased with an
original maturity of three months or less to be cash equivalents. The Company
invests its cash equivalents primarily in overnight repurchase agreements,
money market funds, and United States treasury and agency obligations. At
December 31, 1997 and periodically throughout the year, the Company had cash
balances at certain financial institutions in excess of federally insured
limits. However, the Company does not believe that it is subject to any
unusual credit risk beyond the normal credit risk associated with commercial
banking relationships.
 
  Investments, which are classified as available-for-sale, are recorded at
fair value. Unrealized gains or losses are not immediately recognized but are
reflected as a component of stockholders' equity until realized. Investments
consist of United States treasury and agency bonds, and domestic and foreign
corporate bonds (Note 3). These investments are classified as a current asset
because they are highly liquid and are available, as required, to meet working
capital and other operating requirements.
 
  Other assets include approximately $160,000 of cash maintained in a
restricted escrow account. In April 1997, the Company's primary banking
institution loaned $150,000 to an officer of the Company (the "Loan"). As a
condition to and as security for the Loan, the Bank requested that the Company
pledge to the Bank a certificate of deposit. Such funds will be maintained in
the escrow account until the Loan is repaid.
 
 Financial Instruments
 
  At December 31, 1997 and 1996, the carrying amounts of cash equivalents and
short-term investments approximate fair value because of their high credit
quality, or the short maturity or holding period of these instruments.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
 
 Revenue Recognition and Concentration of Customers
 
  In June 1995, the Company entered into a research and development
collaboration agreement for a certain specified technology with a
pharmaceutical company. Under the terms of the agreement, which originally
would have expired in June 1997, the pharmaceutical company provided funds to
support the research and development of the specified technology. Payments
received were recognized as revenue ratably over the original term of the
agreement which the Company believes corresponded with the manner in which the
work was performed.
 
 Fixed Assets
 
  Furniture and equipment are stated at cost. Depreciation is provided using
the straight-line method based on the estimated useful lives of the assets.
Maintenance and repair expenditures are charged to expense as incurred.
 
 Licensing Fees, Research and Development Expenses, and Concentration of
Outside Researchers
 
  The Company has entered into licensing agreements with certain institutions
that provide the Company with the rights to certain patents and technologies,
and the right to market and distribute any products developed. Obligations
initially incurred to acquire these rights are recognized and expensed on the
date that the Company acquires the rights.
 
  The Company has entered into sponsored research agreements with certain
institutions for the research and development of its licensed technologies.
Payments made under these sponsored research agreements are expensed ratably
over the term of the agreement which the Company believes corresponds with the
manner in which the work is performed.
 
  The Company currently conducts a substantial portion of its research and
development through a certain University and its affiliates pursuant to
sponsored research agreements. The majority of the Company's technologies
currently under development were invented or discovered by researchers working
for this University and its affiliates. A substantial portion of the Company's
research is thus dependent upon a continuing business relationship with this
University.
 
  Research and development activities cease when developmental work is
substantially complete and when the Company believes appropriate efficacy has
been demonstrated. In connection with its merger with Greenwich, the Company
acquired technology related to Therafectin, a treatment for rheumatoid
arthritis. Greenwich had previously conducted clinical trials which management
believes demonstrated the efficacy of the technology. Accordingly, costs
related to Therafectin have been separately stated in the consolidated
statement of operations.
 
 Acquired Technology
 
  In connection with the Merger, $3,500,000 of the purchase price was ascribed
to acquired technology. The Company assesses whether there has been impairment
whenever events or changes in circumstances indicate that any portion of the
carrying amount of the technology may not be recoverable. The Company
evaluates potential impairment by comparing anticipated undiscounted future
cash flows from expected product sales of the technology with its carrying
value. The factors considered by management in performing this assessment
include the expected cost to obtain product approval as well as the effects on
expected product sales of competition, demand, and other economic factors. At
December 31, 1997, management believes that there has been no impairment in
the value of the technology.
 
 Income Taxes
 
  The Company uses the liability method of accounting for income taxes. Under
this method, deferred tax assets and liabilities are recorded for the expected
future tax consequences of temporary differences between the

financial statement and tax bases of assets and liabilities. A valuation
allowance is established to reduce net deferred tax assets to the amount
expected to be realized.
 
 Reverse Stock Split
 
  On June 6, 1997, the Company's stockholders approved a one-for-ten reverse
split of the common stock effective as of June 9, 1997. All share and per
share amounts have been retroactively restated to reflect the terms of the
split.
 
 Net Loss Per Share
 
  In February 1997, The Financial Accounting Standards Board issued Statements
of Financial Accounting Standards (FAS) No. 128, "Earnings per Share". FAS 128
specifies the computation, presentation and disclosure requirements for
earnings per share and is designed to improve earnings per share information
by simplifying the existing computational guidelines, revising the disclosure
requirements, and increasing the comparability of per share data on an
international basis. FAS 128 simplifies the existing computational guidelines
by replacing primary EPS with basic EPS, with the principal difference being
that common stock equivalents are not considered in computing basic EPS. As
long as the Company continues to experience net losses, there will be no
impact to its net loss per share computation since its common stock
equivalents are anti-dilutive and are excluded in computing loss per share, as
noted above. FAS 128 became effective for annual and interim financial
statements issued for periods ending after December 15, 1997 with prior period
EPS data required to be restated. Due to the losses recorded to date, there
was no impact on prior year financial statements as a result of the adoption
of FAS 128.
 
  Basic and diluted net loss per share available to common shareholders has
been calculated by dividing net loss, adjusted for preferred stock
preferences, by the weighted average number of common shares outstanding
during the period. All common stock equivalents have been excluded from the
calculation of weighted average common shares outstanding since their
inclusion would be antidilutive.
 
 Accounting for Stock-Based Compensation
 
  The Company applies APB Opinion No. 25 and related interpretations in
accounting for its stock-based compensation plans and related equity
issuances. Under these standards, no compensation expense is recognized for
stock options issued to employees and directors ("qualified employees")
provided the exercise price for one share of common stock equals the market
price of the Company's common stock at the date of grant. Non-qualified
options issued at less than the market price result in the recognition of
compensation expense equal to the intrinsic value (difference between market
price and exercise price). Options and warrants issued to non-employees are
subject to a fair value based method of accounting under which compensation
cost is generally measured at the vesting date based on the value of the
award. The value is determined using the Black-Scholes pricing model and the
resulting expense is recognized over the vesting period.
 
  In October 1995, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 123, "Accounting for Stock-Based
Compensation" ("FAS 123). The Company has elected to implement FAS 123 on a
disclosure basis only (Note 11).
 
 Use of Estimates
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities, the
disclosure of contingent assets and liabilities at the date of the financial
statements, and the reported amounts of revenues and expenses for the periods
presented. Actual results could differ from those estimates.

 Risks and Uncertainties
 
  The Company is subject to risks and uncertainties common to the
biotechnology industry. Such risks and uncertainties include, but are not
limited to: (i) results from current and planned clinical trials, (ii)
scientific data collected on technologies currently in preclinical research
and development, (iii) decisions made by the Food and Drug Administration
("FDA") or other regulatory bodies with respect to the initiation of human
clinical trials and the commercial sale of any proposed products, (iv) the
Company's ability to obtain the necessary patents and proprietary rights to
effectively protect its technologies, and (v) the outcome of any current or
future collaborations or alliances with pharmaceutical or other biotechnology
companies.
 
 Reclassifications
 
  Certain reclassifications have been made to the 1996 and 1995 financial
statements to conform to the 1997 presentation. These reclassifications had no
effect on net loss for 1996 and 1995.
 
2. ACQUISITION AND MERGER WITH GREENWICH
 
  The acquisition of Old BLSI by Greenwich (the "Merger") has been treated as
a recapitalization of Old BLSI with Old BLSI as the acquiror (reverse
acquisition). The historical financial statements prior to June 15, 1995 are
those of Old BLSI. Historical stockholders' equity of Old BLSI prior to the
Merger has been retroactively restated for the equivalent number of shares
received in the Merger after giving effect to any difference in par value of
Greenwich's and Old BLSI's common stock, with an offset to paid-in capital.
Under the terms of the Merger, the outstanding shares of common stock of BLSI
were exchanged for approximately 4.35 million shares of the Company's common
stock. The total purchase price, including approximately 3.52 million shares
of the Company's common stock (with a value of approximately $14.3 million),
transaction costs, and the value ascribed to outstanding Greenwich stock
options and warrants, was approximately $15.5 million. Under the purchase
method used to account for this transaction, the purchase price was allocated
based on the estimated fair value of the assets and liabilities acquired at
the date of acquisition. Based upon management's review and the results of an
independent appraisal, $3.5 million of the purchase price was ascribed to
acquired technology (Notes 1 and 5). In addition, approximately $10.4 million
of the purchase price was allocated to acquired research and development in-
process, whereby appropriate efficacy had not been demonstrated and no
alternative future use identified. Accordingly, such amount was expensed in
the 1995 statement of operations. The results of operations of Greenwich have
been consolidated with the Company's results from June 15, 1995.
 
  The following unaudited pro forma summary presents the consolidated results
of operations assuming that the merger of Greenwich and Old BLSI (the
"Merger") had occurred on January 1, 1995. No adjustments are required to
conform the accounting policies of Old BLSI and Greenwich. These pro forma
results have been prepared for comparative purposes only and do not purport to
be indicative of what would have occurred had the transaction been effected on
the date indicated above or of results which may occur in the future. In
addition, for purposes of preparing the pro forma information, the $10.4
million charge for in-process research and development resulting from the
acquisition has been excluded.

5. ACQUIRED TECHNOLOGY
 
  In connection with the Merger, a $3.5 million asset was established
representing the appraised value assigned to Therafectin technology acquired
from Greenwich Pharmaceuticals. The Company completed a Phase III clinical
trial for Therafectin in August 1997. On September 30, 1997, the Company
reported that a preliminary analysis of the results indicated that a
statistically significant difference between Therafectin(R) and placebo in the
percentage of patients achieving the overall composite efficacy index had not
been realized. However, further analysis of the trial data using more modern
measurement criteria supports the therapeutic efficacy of Therafectin. Based
upon evaluation of all of the trial data on Therafectin, including data from
previous Greenwich trials, and the advice obtained from a special panel of
clinical rheumatologists, the Company announced, in January 1998, its intent
to seek marketing approval for Therafectin. If the Company is ultimately
unsuccessful in obtaining regulatory approval for Therafectin, the Company may
be required to write off all or some portion of the $3.5 million asset value
attributable to Therafectin as reflected on the Company's balance sheet.

6. RESEARCH AND DEVELOPMENT AGREEMENT
 
  In June 1995, the Company entered into a research and development
collaboration agreement with a pharmaceutical company in the United Kingdom to
develop small molecule inhibitors of Major Histocompatibilty Complex (MHC)
Class II gene transcription to treat autoimmune diseases. Under the terms of
the agreement, which formally expired in June 1997, the pharmaceutical company
provided funds to support the research and development of the specified
technology. These funds were recognized as revenue ratably over the original
term of the Agreement, and totaled $83,060, $200,000 and $166,940 during 1997,
1996 and 1995, respectively. In addition to providing funding, the
pharmaceutical company has been screening its molecule collection, seeking to
identify an inhibitor of the Company's transcription factor. The
pharmaceutical company holds a product development option which it may
exercise, at a cost of $300,000, at any time prior to the expiration of the
agreement. The pharmaceutical company requested, and was granted, an extension
until May 1998, to complete the screening of its molecule collection before
deciding if it will exercise its product development rights. If the
pharmaceutical company exercises its product development option and attains
certain product development milestones, as defined, the Company will receive
milestone payments as defined. The Company is also entitled to receive
royalties from the sale of any products originating from the collaboration.

8. NOTES PAYABLE AND DEBT
 
 Notes Payable
 
  In July 1997, the Company made the final $9,900 monthly payment on a note
with an imputed annual interest rate of 13.26%.
 
 Senior Bridge Notes
 
  In March 1995, Old BLSI executed unit purchase agreements with certain
investors whereby Old BLSI raised an aggregate amount of $2,175,000 through a
bridge loan financing. The unit purchase agreements included 65,250 shares of
Old BLSI common stock and warrants to purchase 130,500 shares of Old BLSI
Series B Preferred Stock. In connection with the Merger, such warrants were
exchanged for warrants to purchase 783,761 shares of the Company's common
stock exercisable at prices ranging from $1.50 to $10.00 per share (Note 11).
 
  In connection with the financing, the placement agent, a related party (Note
14), received fees totaling approximately $320,000 and warrants currently
exercisable for 98,212 shares of common stock at prices ranging from $0.10 to
$11.00 per share (Note 11).

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
 
  In connection with the issuance of the notes, approximately $603,000 of the
issuance price was ascribed to the common stock and warrants included in the
unit purchase and was treated as a discount on the notes. In addition, the
warrants issued to the placement agent were ascribed a value of approximately
$53,000 and were included in deferred financing fees. The debt discount and
deferred financing fees were amortized over the term of the notes which were
repaid in full on March 31, 1996.
 
  In connection with the Company extending the maturity of certain of the
notes by approximately 60 days, the Company issued additional warrants to
purchase 23,175 shares of the Company's common stock with an exercise price of
$3.50 per share (Note 11). The ascribed value of approximately $143,000 for
these additional warrants was recorded as interest expense in 1995.
 
 7% Convertible Subordinated Debentures
 
  In December 1995, the Company issued, pursuant to an investment agreement
(the "Subscription Agreement") under Regulation S of the Securities Act of
1933, an aggregate of $1 million of 7% convertible subordinated debentures
maturing in December 1997. The debentures were convertible, at the option of
the holder, into shares of common stock at sixty-five percent of the market
price of the common stock at the time of conversion. In addition, the
Subscription Agreement contained certain restrictions on the sale of common
stock issued upon conversion of the debentures. Because of the significant
discount associated with the conversion feature, an estimated value of
approximately $411,000 was ascribed to such feature and was recorded as a debt
discount and additional paid-in capital. The debt discount was initially being
amortized over the period the debentures were expected to be outstanding. In
February 1996, the holder elected to convert all of the 7% convertible
debentures into 156,605 shares of common stock. Approximately $70,000 of the
debt discount was amortized and recognized as interest expense in 1996 prior
to the conversion. The remaining unamortized discount and related deferred
financing fees were included in the carrying amount of the debt upon
conversion.
 
9. COMMON STOCK
 
 Common Stock Subject to Redemption
 
  In September and November 1995, the Company sold, pursuant to investment
agreements (each, individually, the "September Investment Agreements" and the
"November Investment Agreements") under Regulation S of the Securities Act of
1933, an aggregate of approximately 320,000 shares of common stock resulting
in net proceeds of approximately $1.8 million. Both agreements provided that,
based upon the average price of the Company's common stock through June 1996
and July 1996 for the September Investment Agreements and the November
Investment Agreements, respectively, (i) the Company was contingently
obligated to issue additional shares of common stock to the investors, (ii)
such investors were contingently obligated to make additional payments to the
Company for shares purchased, and (iii) the Company was contingently obligated
to make repayment to such investors for certain amounts of the investment.
Until the circumstances providing for the possible repayment by the Company of
certain amounts of the equity investment no longer existed, the portion of the
net proceeds which the Company was contingently obligated to repay was
classified as common stock subject to redemption on the Company's balance
sheet. The portion of the equity investment that was no longer subject to
possible repayment was reclassified to stockholders' equity upon the
expiration of the valuation periods as defined in the investment agreements.
 
  In December 1995, $175,000 of the net proceeds subject to redemption was
reclassified to equity concurrent with the expiration of the first valuation
period. During 1997 and 1996, the Company received approximately $29,000 and
$135,000, respectively, in additional payments from the investors based upon
the average price of the Company's common stock for certain periods specified
in the agreements. Also in 1996, the amount of $1,630,000 previously
classified as common stock subject to redemption was reclassified to
stockholders' equity.

 Common Stock Issuance
 
  In June 1996, the Company completed a private placement of 500,000 shares of
common stock which raised approximately $5 million in net proceeds. In
connection with this financing, the Company issued to the placement agent, as
payment for its services, 47,274 shares of common stock and warrants to
purchase 54,727 shares at a price of $11.00 per share (Note 11).
 
10. PREFERRED STOCK
 
  The Company has authorized 1,000,000 shares of preferred stock of which
264,000 shares have been designated as Series A Convertible Preferred Stock.
The remaining authorized shares have not been designated.
 
  In January and February 1996, the Company raised, through a private
placement of its securities, net proceeds of approximately $20.6 million, net
of approximately $3.4 million of issuance costs. In connection with the
private placement, the Company issued (i) 239,910 shares of Series A
Convertible Preferred Stock and (ii) granted warrants to purchase 599,775
shares of common stock at $6.71 per share (Note 11). The warrants may be
redeemed at the election of the Company, in whole but not in part, under
certain conditions as defined in the warrant agreements. In connection with
this financing, the Company granted to the placement agent, a related party
(Note 14), options to acquire 23.991 units with each unit consisting of 1,000
shares of Series A Convertible Preferred stock and warrants to purchase 2,500
shares of common stock at a unit exercise price of $110,000. These options
expire in February 2006.
 
  Each share of the Series A Convertible Preferred Stock is convertible at any
time at the option of the holder into shares of common stock pursuant to a
ratio of 17.53771 shares of common stock for each share of Series A
Convertible Preferred Stock. The Company may, under certain conditions defined
in the preferred stock agreement, cause the conversion of the preferred stock,
in whole or in part, into common stock. The Company issued 1,845,634 and
1,864,276 shares of common stock during 1997 and 1996, respectively, related
to the conversion of 105,238 and 106,301 shares of preferred stock,
respectively.
 
  In a 1997 announcement, the staff of the Securities and Exchange Commission
("SEC") indicated that when preferred stock is convertible at a discount from
the then current common stock market price, the discounted amount reflects at
that time an incremental yield , e.g. a "beneficial conversion feature", which
should be recognized as a return to the preferred shareholders. Based on the
market price of the Company's common stock on the various dates of issuance,
the preferred stock had a beneficial conversion feature of $28,389,846 at such
point in time. In addition, the warrants had a fair value of $5,998,107. The
beneficial conversion feature and the value attributable to the warrants
totaled $34,387,953 which was included in calculating the net loss available
to common shareholders for the year ended December 31, 1996. These preferred
stock preferences represent a non-cash charge in the determination of net loss
available to common shareholders.
 
11. STOCK OPTIONS AND WARRANTS
 
 Stock Option Plans
 
  In connection with the Merger (Note 2), the restated and amended Greenwich
Omnibus Stock Option Plan was adopted on June 15, 1995 and renamed the BLSI
Amended and Restated Omnibus Stock Plan (the "Omnibus Plan"). In connection
with the Merger and in exchange for options to purchase Old BLSI common stock
held by certain employees, officers, consultants, directors and members of the
Scientific Board of Old BLSI which were outstanding on June 15, 1995, the
Omnibus Plan provided for a one-time grant to these individuals of options to
purchase, at an exercise price of $.80 per share, up to 399,770 shares of the
Company's common

stock. All options granted prior to the Merger under the Greenwich Omnibus
Stock Option Plan expired as of December 31, 1996. In addition, in connection
with the Merger, the amended and restated Greenwich 1990 Non-Employee
Directors' Non-Qualified Stock Option Plan was adopted on June 15, 1995 and
renamed the BLSI Amended and Restated 1990 Non-Employee Directors' Non-
Qualified Stock Option Plan (the "Director's Plan", and together with the
Omnibus Plan, the "Amended and Restated Option Plans"). As a result of the
adoption of the Amended and Restated Option Plans, all other stock option
plans of Greenwich and Old BLSI were terminated.
 
 Omnibus Plan
 
  The Omnibus Plan provides for the issuance of both nonqualified stock
options and incentive stock options to employees, officers, consultants and
scientific advisors of the Company. The Omnibus Plan allows for the issuance
of options to purchase up to 1,200,000 shares of the Company's common stock
through April 2005. The Company's Board of Directors determines the term of
each option, option price, number of shares for which each option is granted
and the rate at which each option is exercisable. The term of each option
cannot exceed ten years. The exercise price of incentive stock options shall
not be less than the fair market value of the Company's common stock on the
date of grant. Nonqualified stock options may be issued under the Omnibus Plan
at an option price determined by the Board of Directors which shall not be
less than 50% of the fair market value of the Company's common stock on the
date of grant.
 
  In 1995 and 1996, the Company granted, in recognition of services to be
performed by certain employees, consultants and scientific advisors, non-
qualified stock options under the Omnibus Plan. Options granted totaled 75,600
and 30,400 during 1996 and 1995, respectively. The total value (intrinsic and
fair value) of approximately $274,000 and $236,000 ascribed to the options
granted in 1996 and 1995, respectively, was recorded as deferred compensation
and is being charged to operations over the vesting period of the options
which management believes fairly approximates the service period. The charge
to operations for the years ended December 31, 1997, 1996 and 1995 totaled
approximately $182,000, $292,000 and $13,000, respectively.
 
 Directors' Plan
 
  The Directors' Plan allows for the issuance of up to 300,000 shares of the
Company's common stock through April 2005. The Director's Plan provides for an
automatic yearly grant of options to all non-employee directors of up to 2,500
options. Non-qualified stock options granted under the Directors' Plan
generally vest 75% six months from the grant date and the remaining 25% on the
later of six months from the date of grant or December 31st of the year of
grant, and have an exercise price equivalent to 20% of the quoted market price
of the Company's common stock on the date of grant. For new non-employee
Directors, the Directors' Plan also provides for the one-time issuance of
options to purchase 7,500 shares of the Company's common stock at fair market
value at the time of grant with such options vesting over a period of four
years. During 1996, the Directors' Plan was amended to provide for the
granting of additional options at the discretion of the Board of Directors.
All options granted under the Directors' Plan have a term of ten years.
Compensation expense related to the intrinsic value of options issued in 1997,
1996 and 1995 totaled approximately $18,000, $98,000 and $7,500, respectively.

dividend yield of zero percent; expected volatility of 80 percent; risk-free
interest rates, based on the date of grant, ranging from 5.38% to 6.46%; and
expected lives of 5 years.

 Stockholder Rights Plan
 
  On September 29, 1991, the Board of Directors of Greenwich adopted a
Stockholder Rights Plan (the "Rights Plan"), which was amended during 1994 and
1993 and adopted by the Company in connection with the Merger (Note 2). Under
the Rights Plan, stockholders received as a dividend, for each share of common
stock owned by them, one right (the "Right") to purchase a fractional share of
a new class of preferred stock. With certain exceptions, if a person or group
(the "Acquirer") acquires 15 percent (the "trigger point") or more of the
outstanding shares of the Company's common stock, the Rights will separate
from the shares of common stock and become exercisable. Once the Rights are
exercised, and in certain circumstances if additional conditions are met, the
Rights Plan allows holders of the Rights (other than the Acquirer) to buy
common stock of the Company or the Acquirer at a substantial discount. The
Rights dividend was issued to stockholders of record on October 7, 1991. The
Rights will expire in ten years unless exercised by the holders or redeemed or
exchanged by the Company.

  The Company has provided a full valuation allowance for its deferred tax
assets since realization of these future benefits is not sufficiently assured.
In the event the Company achieves profitability, these deferred tax assets
will be available to offset future income tax liabilities and expense.
Approximately $7 million of the valuation allowance at December 31, 1997
relates to deferred tax assets acquired in the merger with Greenwich (Note 2).
When the valuation allowance related to these assets is released, the credits
will first be recorded to reduce the carrying value, if any, of acquired
technology purchased in the Merger.

</TABLE>
 
  A portion of the net operating loss carryforwards totaling approximately
$864,000 relates to deductions for the exercise of non-qualified options and
will be credited to additional paid-in capital upon realization.
 
  In connection with the Merger (Note 2), the Company acquired approximately
$90 million of net operating loss carryforwards of which approximately $11.6
million can be utilized by the Company under the ownership change provisions
of the Internal Revenue Code. These net operating losses, which expire in 2009
and 2010, cannot offset the taxable income of any of the subsidiaries of the
Company. In addition, ownership changes resulting from the Company's issuance
of common stock may limit the amount of net operating loss and tax credit
carryforwards that can be utilized annually to offset future taxable income.
The amount of the annual limitation is determined based upon the Company's
value immediately prior to the ownership change. Subsequent significant
changes in ownership could further affect the limitation in future years.
 
13. COMMITMENTS AND CONTINGENCIES
 
 Operating Leases
 
  The Company leases certain office equipment and its office space and
warehouse facilities under noncancelable operating leases. Terms of the lease
for office space include a renewal option of three years.

14. RELATED PARTY TRANSACTIONS
 
 Placement Agent Fees
 
  The Chief Executive Officer and sole stockholder of the placement agent
("Principal Agent") involved with a significant portion of the Company's prior

During the three years ended December 31, 1997, compensation to the Principal

</TABLE>
 
  In addition, the Principal Agent received options to acquire 23.991 units in
connection with the Company's 1996 private placement of Series A Convertible
Preferred Stock (Note 10). Each unit consists of 1,000 shares of Series A
Convertible Preferred Stock and warrants to purchase 2,500 shares of common
stock at a unit exercise price of $110,000.
 
 Service Agreements with Placement Agent
 
  In August 1995, the Company entered into a two-year financial advisory
services agreement with the Principal Agent. In connection with the agreement,
the Company issued warrants to the Principal Agent for the purchase of 25,000
shares of the Company's common stock (Note 11).
 
  In February 1996, the Company entered into a two-year agreement under which
the Principal Agent receives a monthly retainer fee of $2,500 per month. The
Principal Agent will also receive standard success fees, on terms to be
determined, for corporate partners first introduced to the Company by the
Principal Agent.
 
  In April 1997, the Bank loaned $150,000 to Dr. Lanser, the Company's
Executive Vice President and Chief Scientific Officer (the "Loan"). The Loan
bears interest at prime and matures in its entirety on September 15, 1998. As
a condition to and as security for the Loan, the Bank requested that the
Company pledge to the Bank a

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
certificate of deposit in the amount of $155,000 (the "Company Pledge"). In
recognition of Dr. Lanser's past and expected future contributions to the
Company and as an additional motivation and incentive to Dr. Lanser, which the
Company's Board of Directors determined would reasonably benefit the Company,
the Company agreed to provide the Company Pledge. As security for the Company,
however, in the event Dr. Lanser defaults on the Loan and the Bank forecloses
on the Company Pledge, Dr. Lanser has executed and delivered to the Company
his contingent note in the amount of $150,000, bearing interest identical to
the Loan (the "Contingent Note") and a perfected pledge of 50,000 shares of
Common Stock of the Company which he beneficially owns. The Company will
demand payment of the Contingent Note only in the event that the Bank
forecloses on the Company Pledge as a result of Dr. Lanser's defaulting on his
payment of the Loan.

               AMENDED AND RESTATED CERTIFICATE OF INCORPORATION

                                      OF

                          BOSTON LIFE SCIENCES, INC.



          Boston Life Sciences, Inc. (the "Corporation), a corporation organized
and existing under and by virtue of the General Corporation Law of the State of
Delaware, DOES HEREBY CERTIFY:

          1.   The name of the Corporation is Boston Life Sciences, Inc. (the
"Corporation").  The Corporation is the entity resulting from the merger of
Boston Life Sciences, Inc., a Massachusetts corporation, with and into Greenwich
Pharmaceuticals Incorporation, a Delaware corporation, on June 15, 1995.  A
Certificate of Merger was filed with the Secretary of State of Delaware on that
date.  The Corporation was originally incorporated on May 18, 1972 under the
name "Strategic Medical Research Corp."

          2.   This Amended and Restated Certificate of Incorporation amends and
restates the Restated Certificate of Incorporation to restate the certificate of
incorporation of the Corporation in its entirety in a single document.

          3.   The text of the Restated Certificate of Incorporation is further
amended and restated hereby to read as herein set forth in full:

                         "FIRST:  The name of the corporation is Boston Life
               Sciences, Inc. (the "Corporation");

                    manufacture, use, apply, and generally to deal in and with

<PAGE>
 
                         (f) To engage in any and all business activities and

                    Corporation Law of Delaware, to engage in any lawful act or

                    General Corporation Law of Delaware.

                         FOURTH:    The aggregate number of shares which the
               Corporation shall have authority to issue is 176,000,000 to be
               divided into (a) 175,000,000 shares of Common Stock, par value
               $.01 per share, (b) 1,000,000 shares of Preferred Stock, par
               value $.01 per share, of which 264,000 shares are designated as
               Series A Convertible Preferred Stock, par value $.01 per share,
               with the powers, preferences and other rights as described on
               Exhibit A attached hereto and made a part hereof.

                         The Board of Directors is hereby empowered to cause the
               Preferred Stock to be issued from time to time for such
               consideration as it may from time to time fix, and to cause such
               Preferred Stock to be issued in series with such voting powers,
               designations, preferences and relative, participating, optional
               or other special rights, if any, or the qualifications,
               limitations or restrictions thereof, as designated by the Board
               of Directors in the resolution providing for the issue of such
               series.  Shares of Preferred Stock of any one series shall be
               identical in all respects.

                    FIFTH:    In furtherance and not in limitation of the power
          conferred by statute, the Board of Directors is expressly authorized
          to make, repeal, alter, amend and rescind the By-laws of the
          Corporation.

                    SIXTH:    No director of the Corporation shall be personally
          liable to the Corporation or any of its stockholders for monetary
          damages for breach of fiduciary duty as a director, except for
          liability (i) for any breach of the director's duty of loyalty to the
          Corporation or its stockholders, (ii) for acts or omissions not in
          good faith or which involve intentional misconduct or a knowing
          violation of law, (iii) under Section 174 of the Delaware General


                                       3
<PAGE>
 
          Corporation Law, as the same exists or hereafter may be amended, or
          (iv) for any transaction from which the director derived an improper
          personal benefit.  If the Delaware General Corporation Law hereafter
          is amended to authorize the further elimination or limitation of the
          liability of directors, then the liability of a director of the
          Corporation, in addition to the limitation on personal liability
          provided herein, shall be limited to the fullest extent permitted by
          the amended Delaware General Corporation Law.  Any repeal or
          modification of this paragraph by the stockholders of the Corporation
          shall be prospective only, and shall not adversely affect any
          limitation on the personal liability of a director of the Corporation
          existing at the time of such repeal or modification.

                    SEVENTH:  Any action required or permitted to be taken at
          any annual or special meeting of stockholders may be taken only upon
          the vote of the stockholders at an annual or special meeting duly
          called and may not be taken by written consent of the stockholders.
          Special meetings of the stockholders of the Corporation for any
          purpose or purposes may be called at any time by the Board of
          Directors, the Chairman of the Board of Directors or the President of
          the Corporation.  Special meetings of the stockholders of the
          Corporation may not be called by any other person or persons.

                    EIGHTH:   This Amended and Restated Certificate of
          Incorporation may be amended by the affirmative vote of the majority
          of the shares entitled to vote on each such amendment."

          4.   This Amended and Restated Certificate of Incorporation was duly
adopted by the board of directors and by the stockholders in accordance with the
provisions of Sections 242 and 245 of the Delaware General Corporation Law.

                                   EXHIBIT A
                                   ---------

                     Series A Convertible Preferred Stock
                     ------------------------------------


        1.  Designation and Amount.  There shall be a series of Preferred Stock 
            ----------------------
designated as "Series A Convertible Preferred Stock" and the number of shares 
constituting such series shall be 264,000.  Such series is referred to herein as
the "Series A Convertible Preferred Stock".  Such number of shares may be 
increased or decreased by resolution of the Board of Directors of the 
Corporation; provided, however, that no decrease shall reduce the number of 
shares of Series A Convertible Preferred Stock to less than the number of shares
then issued and outstanding.

        2.  Dividends.  Subject to the prior and superior rights of the holders 
            ---------
of any shares of any series of Preferred Stock ranking and superior to the 
shares of Series A Convertible Preferred Stock with respect to dividends and 
distributions, the holders of shares of Series A Convertible Preferred Stock, 
shall be entitled to receive dividends and distributions, when, as and if 
declared by the Board of Directors out of funds legally available for such 
purpose.  If the Corporation declares a dividend





                           [CONTINUED ON NEXT PAGE]


<PAGE>
 
or distribution on the common stock, par value $.01 per share (the "Common 
Stock"), of the Corporation, the holders of shares of Series A Convertible 
Preferred Stock shall be entitled to receive for each share of Series A 
Convertible Preferred Stock a dividend or distribution in the amount of the 
dividend or distribution that would be received by a holder of the Common Stock 
into which such share of Series A Convertible Preferred Stock is convertible on 
the record date for such dividend or distribution. If the Corporation declares a
dividend or distribution on any other class or series of preferred stock, the 
holders of shares of Series A Convertible Preferred Stock shall be entitled to 
receive a dividend or distribution in an amount per share in proportion to the 
dividend or distribution declared on a share of such other class or series based
upon the liquidation preference of a share of the Series A Convertible Preferred
Stock relative to that of a share of such other class or series, unless the 
holders of at least 66-2/3% of the outstanding shares of Series A Convertible 
Preferred Stock consent otherwise. In any such case, the Corporation shall 
declare a dividend or distribution on the Series A Convertible Preferred Stock 
at the same time that it declares a dividend or distribution on the Common Stock
or such other class or series of preferred stock and shall establish the same 
record date for the dividend or distribution on the Series A Convertible 
Preferred Stock as is established for such dividend or distribution on the 
Common Stock or such other class or series of preferred stock. Each such 
dividend or distribution will be payable to holders of record of the Series A 
Convertible Preferred Stock as they appeared on the records of the Corporation 
at the close of business on the record date declared for such dividend or 
distribution, as shall be fixed by the Board of Directors. If the corporation 
declares or pays a dividend or distribution on the Series A Convertible 
Preferred Stock as a result of the declaration or payment of a dividend or 
distribution on the Common Stock or any other class or series of preferred stock
as described above, the holders of the Series A Convertible Preferred Stock 
shall not be entitled to any additional dividend or distribution solely because 
such first dividend or distribution also required the declaration or payment of 
a dividend or distribution on any other class or series of preferred stock. Any 
reference to "distribution" contained in this Section 2 shall not be deemed to 
include any distribution made in connection with any liquidation, dissolution or
winding up of the Corporation, whether voluntary or involuntary.

     3.  Liquidation Preference.  (a)  In the event of a (i) liquidation, 
         ----------------------
dissolution or winding up of the Corporation, whether voluntary or involuntary 
or (ii) a sale or other disposition of all or substantially all of the assets of
the Corporation (a "Liquidation Event"), after payment or provision for payment 
of debts and other liabilities of the Corporation, the holders of the Series A 
Convertible Preferred Stock then outstanding shall be entitled to be paid out of
the assets of the Corporation available for distribution to its shareholders, 
whether such assets are capital, surplus, or earnings, before any payment or 
declaration and setting apart for payment of any amount shall be made in respect
of the stock junior to the Series A Convertible Preferred Stock, an amount equal
to $130.00 per share plus an amount equal to all declared and unpaid dividends 
thereon. If upon any Liquidation Event, whether voluntary or involuntary, the 
assets to be distributed to holders of the Series A Convertible Preferred Stock 
shall be insufficient to permit the payment to such shareholders of the full 
preferential amounts aforesaid, then all of the assets of the Corporation to be 
distributed shall be so distributed ratably to the holders of the Series A 
Convertible Preferred Stock on the basis of the number of shares of Series A 
Convertible Preferred Stock held. A consolidation or merger of the Corporation 
with or into another corporation shall not be considered a liquidation, 
dissolution or winding up of the Corporation or a sale or other disposition of 
all or substantially all of the assets of the Corporation. All shares of Series 
A Convertible Preferred Stock shall rank as to payment upon the occurrence of 
any of the events described in clauses (i) and (ii) above senior to the Common 
Stock as provided herein and, unless the terms of such series shall provide 
otherwise, senior to all other series of the Corporation's preferred stock.

                                       2
<PAGE>
 
          (b)  After the payment or distribution to the holders of the Series A 
Preferred Stock of the full preferential amounts aforesaid, the holders of 
shares of the Common Stock and any other shares of participating preferred stock
then outstanding will be entitled to receive, pro rata an amount per share equal
                                              --- ----
to $13 plus accrued but unpaid dividends, if any, paid to the holders of the 
Series A Convertible Preferred Stock. After the payment or distribution pursuant
to the immediately preceding sentence, the holders of shares of the Series A 
Convertible Preferred Stock, the Common Stock and any other shares of 
participating preferred stock then outstanding will share any remaining assets 
of the Corporation on a pari passu, as converted basis. 
                        ---- -----

          4.   Conversion.
               ----------
 
          (a) Right of Conversion. The shares of Series A Convertible Preferred
              ------------------- 
Stock shall be convertible, in whole or in part, at the option of the holder
thereof and upon notice to the Corporation as set forth in paragraph (b) below,
into fully paid and nonassessable shares of Common Stock and such other
securities and property as hereinafter provided. The shares of Series A
Convertible Preferred Stock shall be convertible initially at the rate of
175.3771 shares of Common Stock for each full share of Series A Convertible
Preferred Stock and shall be subject to adjustment as provided herein. The
initial conversion price per share of Common Stock is $.5702 and shall be
subject to adjustment as provided herein. For purposes of this resolution, the
"conversion rate" applicable to a share of Series A Convertible Preferred Stock
shall be the number of shares of Common Stock and number or amount of any other
securities and property as hereinafter provided into which a share of Series A
Convertible Preferred Stock is then convertible and shall be determined by
dividing the then existing conversion price into $100.00.

          Subject to adjustment pursuant to the provisions of paragraph (c) 
below, in the event that the conversion price in effect at the time of each 
Interim Closing Date (as defined below) and the Final Closing Date (as defined 
below) is greater than 85% of the average closing bid price of the Common Stock 
for the thirty consecutive trading days immediately preceding (x) any interim 
closing date of the issuance and sale of the Series A Convertible Preferred
Stock (each an "Interim Closing Date") or (y) the final closing date of the
issuance and sale of the Series A Convertible Preferred Stock (the "Final
Closing Date"), then the conversion price shall be adjusted to equal the lesser
of any such average closing bid price. If there is any change in the conversion
price as a result of the preceding sentence, then the conversion rate shall be
changed accordingly, and shall be determined by dividing the new conversion
price into $100.00. The Corporation shall prepare a certificate signed by the
principal financial officer of the Corporation setting forth the conversion rate
as of the Final Closing Date, showing in reasonable detail the facts upon which
such conversion rate is based, and such certificate shall forthwith be filed
with the transfer agent of the Series A Convertible Preferred Stock.
Notwithstanding the provisions of subparagraph (vi) of paragraph (c) below, a
notice stating that the conversion rate has been adjusted pursuant to this
paragraph, or that no adjustment is necessary, and setting forth the conversion
rate in effect as of the Final Closing Date shall be mailed as promptly as
practicable after the Final Closing Date by the Corporation to all record
holders of Series A Convertible Preferred Stock at their last addresses as they
shall appear in the stock transfer books of the Corporation.

          Subject to adjustment pursuant to the provisions of paragraph (c) 
below, the conversion price in effect immediately prior to the date that is 12 
months after the Final Closing Date of the issuance and sale of the Series A 
Convertible Preferred Stock (the "Reset Date") shall be adjusted and reset 
effective as of the Reset Date if the average closing bid price of the Common 
Stock for the 30

                                       3
<PAGE>
 
consecutive trading days immediately preceding the Reset Date (the "12-Month 
Trading Price") is less than 130% of the then applicable conversion price (a 
"Reset Event"). Upon the occurrence of a Reset Event, the conversion price shall
be reduced to be equal to the greater of (A) the 12-Month Trading Price divided 
by 1.3, (B) 50% of the then applicable conversion price and (C) $.375 (subject 
to a proportional adjustment in the event of an adjustment to the conversion 
price pursuant to paragraph 4(c) below). If there is any change in the 
conversion price as a result of the preceding sentence, then the conversion rate
shall be changed accordingly, and shall be determined by dividing the new 
conversion price into $100.00. The Corporation shall prepare a certificate 
signed by the principal financial officer of the Corporation setting forth the 
conversion rate as of the Reset Date, showing in reasonable detail the facts 
upon which such conversion rate is based, and such certificate shall forthwith 
be filed with the transfer agent of the Series A Convertible Preferred Stock. 
Notwithstanding the provisions of subparagraph (vi) of paragraph (c) below, a 
notice stating that the conversion rate has been adjusted pursuant to this 
paragraph, or that no adjustment is necessary, and setting forth the conversion 
rate in effect as of the Reset Date shall be mailed as promptly as practicable 
after the Reset Date by the Corporation to all record holders of the Series A 
Convertible Preferred Stock at their last addresses as they shall appear in the 
stock transfer books of the Corporation.

          The "closing bid price" for each trading day shall be the reported 
closing bid price on the NASDAQ Small-Cap Market or the NASDAQ National Market 
System (collectively referred to as, "NASDAQ") or, if the Common Stock is not 
quoted on NASDAQ, on the principal national securities exchange on which the 
Common Stock is listed or admitted to trading (based on the aggregate dollar 
value of all securities listed or admitted to trading) or, if not listed or 
admitted to trading on any national securities exchange or quoted on NASDAQ, the
closing bid price in the over-the-counter market as furnished by any NASD member
firm selected from time to time by the Corporation for that purpose, or, if such
prices are not available, the fair market value set by, or in a manner 
established by, the Board of Directors of the Corporation in good faith. 
"Trading day" shall mean a day on which the national securities exchange or 
NASDAQ used to determine the closing bid price is open for the transaction of 
business or the reporting of trades or, if the closing bid price is not so 
determined, a day on which NASDAQ is open for the transaction of business.

          (b)   Conversion Procedures.  Any holder of shares of Series A 
                ---------------------
Convertible Preferred Stock desiring to convert such shares into Common Stock 
shall surrender the certificate or certificates evidencing such shares of Series
A Convertible Preferred Stock at the office of the transfer agent for the Series
A Convertible Preferred Stock, which certificate or certificates, if the 
Corporation shall so require, shall be duly endorsed to the Corporation or 
in blank, or accompanied by proper instruments of transfer to the Corporation or
in blank, accompanied by irrevocable written notice to the Corporation that the 
holder elects so to convert such shares of Series A Convertible Preferred Stock 
and specifying the name or names (with address) in which a certificate or 
certificates evidencing shares of Common Stock are to be issued. The Corporation
need not deem a notice of conversion to be received unless the holder complies 
with all the provisions hereof. The Corporation will instruct the transfer agent
(which may be the Corporation) to make a notation of the date that a notice of 
conversion is received, which date shall be deemed to be the date of receipt for
purposes hereof.

          The Corporation shall, as soon as practicable after such deposit of 
certificates evidencing shares of Series A Convertible Preferred Stock 
accompanied by the written notice and compliance with any other conditions
herein contained, deliver at such office of such transfer agent to the person
for whose account such share of Series A Convertible Preferred Stock were so
surrendered, or to the nominee or nominees of such person, certificates
evidencing the number of full shares of Common Stock to which such person shall
be entitled as aforesaid, together with a cash adjustment of any fraction of a

                                       4

share as hereinafter provided. Subject to the following provisions of this 
paragraph, such conversion shall be deemed to have been made as of the date of 
such surrender of the shares of Series A Convertible Preferred Stock to be 
converted, and the person or persons entitled to receive the Common Stock 
deliverable upon conversion of such Series A Convertible Preferred Stock shall 
be treated for all purposes as the record holder or holders of such Common 
Stock on such date; provided, however, that the Corporation shall not be 
required to convert any shares of Series A Convertible Preferred Stock while the
stock transfer books of the Corporation are closed for any purpose, but the 
surrender of Series A Convertible Preferred Stock for conversion during any 
period while such books are so closed shall become effective for conversion 
immediately upon the reopening of such books as if the surrender had been made 
on the date of such reopening, and the conversion shall be at the conversion 
rate in effect on such date. No adjustments in respect of any dividends on 
shares surrendered for conversion or any dividend on the Common Stock issued 
upon conversion shall be made upon the conversion of any shares of Series A 
Convertible Preferred Stock.

          All notices of conversion shall be irrevocable; provided, however, 
that if the Corporation has sent notice of an event pursuant to Section 4(g) 
hereof, a holder of Series A Convertible Preferred Stock may, at its election, 
provide in its notice of conversion that the conversion of its shares of Series 
A Convertible Preferred Stock shall be contingent upon the occurrence of the 
record date or effectiveness of such event (as specified by such holder), 
provided that such notice of conversion is received by the Corporation prior to 
such record date or effective date, as the case may be.

          (c)  Certain Adjustments of Conversion Rate. In addition to adjustment
               --------------------------------------
pursuant to paragraph (a) above, the conversion rate (and the corresponding 
conversion price) shall be subject to adjustment from time to time as follows:

          (i)  In case the Corporation shall (A) pay a dividend in Common Stock 
     or make a distribution in Common Stock, (B) subdivide its outstanding 
     Common Stock, (C) combine its outstanding Common Stock into a smaller 
     number of shares of Common Stock or (D) issue by reclassification of its 
     Common Stock other securities of the Corporation, then in each such case
     the conversion rate in effect immediately prior thereto shall be adjusted
     so that the holder of any shares of Series A Convertible Preferred Stock
     thereafter surrendered for conversion shall be entitled to receive the kind
     and number of shares of Common Stock or other securities of the Corporation
     which such holder would have owned or would have been entitled to receive
     immediately after the happening of any of the events described above had
     such shares of Series A Convertible Preferred Stock been converted
     immediately prior to the happening of such event or any record date with
     respect thereto. Any adjustment made pursuant to this subparagraph (i)
     shall become effective immediately after the effective date of such event
     retroactive to the record date, if any, for such event.

          (ii)  In case the Corporation shall issue or sell Common Stock or 
     rights, options, warrants or other securities convertible into Common 
     Stock, excluding those rights, options, warrants or other securities 
     convertible into Common Stock already outstanding and disclosed in the 
     Offering Memorandum, at a price per share which is lower than both (A) the 
     then effective conversion price and (B) the closing bid price (as defined 
     in Section 4) for the trading day immediately prior to such record date 
     (the "Current Market Price"), then the conversion rate shall be determined 
     by multiplying the conversion rate theretofore in effect by a fraction, of 
     which the numerator shall be the number of shares of Common Stock 
     outstanding immediately prior to the issuance of such shares, rights, 
     options, warrants or convertible securities plus the number of additional
     shares of Common Stock offered for subscription or purchase, and of which
     the

                                       5

<PAGE>
 
denominator shall be the number of shares of Common Stock outstanding 
immediately prior to the issuance of such rights, options, warrants or 
convertible securities plus the number of shares which the aggregate offering 
price of the total number of shares offered would purchase at the then effective
conversion price. Such adjustment shall be made whenever such rights, options, 
warrants or convertible securities are issued, and shall become effective 
immediately and retroactive to the record date for the determination of 
stockholders entitled to receive such rights, options, warrants or convertible 
securities.

     (iii)  In case the Corporation shall distribute to all or substantially all
holders of its Common Stock evidences of its indebtedness or assets (excluding 
cash dividends or distributions out of earnings) or rights, options, warrants or
convertible securities containing the right to subscribe for or purchase Common 
Stock (excluding those referred to in subparagraph (ii) above), then in each 
case the conversion rate shall be determined by multiplying the conversion rate 
theretofore in effect by a fraction, of which the numerator shall be the then 
fair value as determined in good faith by the Corporation's Board of Directors 
on the date of such distribution, and of which the denominator shall be such 
fair value on such date minus the then fair value (as so determined) of the 
portion of the assets or evidences of indebtedness so distributed or of such 
subscription rights, options, warrants or convertible securities applicable to 
one share. Such adjustment shall be made whenever any such distribution is made 
and shall become effective on the date of distribution retroactive to the record
date for the determination of stockholders entitled to receive such 
distribution.

     (iv)   Upon the expiration of any rights, options, warrants or conversion 
privileges, if such shall not have been exercised, the conversion rate shall, 
upon such expiration, be readjusted and shall thereafter be such as it would 
have been had it been originally adjusted (or had the original adjustment not 
been required, as the case may be) on the basis of (A) the fact that Common 
Stock, if any, actually issued or sold upon the exercise of such rights, 
options, warrants or conversion privileges, and (B) the fact that such shares of
Common Stock, if any, were issued or sold for the consideration actually 
received by the Corporation upon such exercise plus the consideration, if any, 
actually received by the Corporation for the issuance, sale or grant of all such
rights, options, warrants or conversion privileges whether or not exercised.

     (v)    No adjustment in the conversion rate shall be required unless such 
adjustment would require an increase or decrease of at least 1% in such rate; 
provided, however, that the Corporation may make any such adjustment at its 
election; and provided, further, that any adjustments which by reason of this 
subparagraph (v) are not required to be made shall be carried forward and taken 
into account in any subsequent adjustment. All calculations under this Section 4
shall be made to the nearest cent or to the nearest one-hundredth of a share, as
the case may be.

     (vi)   Whenever the conversion rate is adjusted as provided in any 
provision of this Section 4;

            (A)  the Corporation shall compute (or may retain a firm of
     independent public accountants of recognized national standing (which may
     be any such firm regularly employed by the Corporation) to compute) the
     adjusted conversion rate in accordance with this Section 4 and shall
     prepare a certificate signed by the principal financial officer of the
     Corporation (or cause any such independent public accountants to execute a
     certificate) setting forth the adjusted conversion rate and showing in
     reasonable detail the

                                       6
<PAGE>
 
           facts upon which each adjustment is based, and such certificate shall
           forthwith be filed with the transfer agent of the Series A
           Convertible Preferred Stock; and

                 (B)   a notice stating that the conversion rate has been 
           adjusted and setting forth the adjusted conversion rate shall
           forthwith be required, and as soon as practicable after it is
           required, such notice shall be mailed by the Corporation to all
           record holders of Series A Convertible Preferred Stock at their last
           addresses as they shall appear in the stock transfer books of the
           Corporation.

           (vii) In the event that at any time, as a result of any adjustment 
     made pursuant to this Section 4, the holder of any shares of Series A
     Convertible Preferred Stock thereafter surrendered for conversion shall
     become entitled to receive any shares of the Corporation other than shares
     of Common stock or to receive any other securities, the number of such
     other shares or securities so receivable upon conversion of any share of
     Series A Convertible Preferred Stock shall be subject to adjustment from
     time to time in a manner and on terms as nearly equivalent as practicable
     to the provisions contained in this Section 4 with respect to the Common
     Stock.

           (d)   No fractional Shares.  No fractional shares or scrip 
                 --------------------
representing fractional shares of Common stock shall be issued upon conversion 
of Series A Convertible Preferred Stock.  If more than one certificate 
evidencing shares of Series A Convertible Preferred Stock shall be surrendered 
for conversion at one time by the same holder, the number of full shares 
issuable upon conversion thereof shall be computed on the basis of the aggregate
number of shares of Series A Convertible Preferred Stock so surrendered.  
Instead of any fractional share of Common stock which would otherwise be 
issuable upon conversion of any shares of Series A Convertible Preferred Stock, 
the Corporation shall pay a cash adjustment in respect of such fractional 
interest in an amount equal to the same fraction of the market price per share 
of Common Stock (which shall be the closing price as defined in Section 5) at 
the close of business on the day of conversion.

           (e)   Consolidation; Merger; Etc.  If the Corporation shall enter 
                 --------------------------
into any consolidation, merger, combination or other transaction in which shares
of Common Stock constituting in excess of 50% of the voting power of the
Corporation are exchanged for or changed into other stock or securities, cash
and/or any other property (a "Merger Transaction"), then in any such case the
shares of Series A Convertible Preferred Stock shall at the same time be
similarly exchanged or changed in an amount per share equal to (i) the
conversion rate in effect at such time multiplied by (ii) the aggregate fair
market value, as determined in good faith by the Board of Directors of the
Corporation, of stock, securities, cash and/or any other property (payable in
kind), as the case may be, into which or for which each share of Common stock is
changed or exchanged (the "Per Share Merger Consideration"); provided, however,
                                                             --------  -------
that if any stock of securities received in the Merger Transaction are traded on
a securities exchange or quotation system, the fair market value of such stock
or securities shall be the closing sales price of such stock or securities as
reported by the principal exchange or quotation system for such stock or
securities the business day immediately preceding the execution of the merger
agreement or other transaction agreement for such Merger Transaction, and if no
such trading market exists for such stock or securities, the aggregate fair
market value shall be as determined in good faith by the Board of Directors of
the Corporation; provided, further, however, that if any such Merger Transaction
                 --------  -------  -------
is effected on or before the Reset Date, and if the Per Share Merger
Consideration (assuming conversion of all outstanding convertible stock,
including the Series A Convertible Preferred Stock, at the conversion rate for
such stock in effect at the time of the execution and delivery of the merger
agreement relating to such Merger Transaction) is less than 130% of the then
applicable conversion price relating to the Series A Convertible Preferred
Stock, then the conversion price will be reduced to equal the greater of (x) the
Per Share

                                       7
<PAGE>
 
Merger Consideration divided by 1.3, (y) 50% of the then applicable conversion 
price and (z) $.375 (subject to a proportional adjustment in the event of an 
adjustment to the conversion price pursuant to paragraph 4(c) above).

                (f)     Reservation of Shares; Transfer Taxes; Etc.  The 
                        ------------------------------------------
Corporation shall at all times reserve and keep available, out of its authorized
unissued stock, solely for the purpose of effecting the conversion of the Series
A Convertible Preferred Stock, such number of shares of its Common Stock free of
preemptive rights as shall from time to time be sufficient to effect the 
conversion of all shares of Series A Convertible Preferred Stock from time to 
time outstanding.  The Corporation shall use its best efforts from time to time,
in accordance with the laws of the State of Delaware, to increase the authorized
number of shares of Common Stock if at any time the number of shares of Common 
Stock not outstanding shall not be sufficient to permit the conversion of all 
the then-outstanding shares of Series A Convertible Preferred Stock.

                The Corporation shall pay any and all issue or other taxes that
may be payable in respect of any issue or delivery of shares of Common Stock on
conversion of the Series A Convertible Preferred Stock. The Corporation shall
not, however, be required to pay any tax which may be payable in respect of any
transfer involved in the issue or delivery of Common Stock (or other securities
or assets) in a name other than that in which the shares of Series A Convertible
Preferred Stock so converted were registered, and no such issue or delivery
shall be made unless and until the person requesting such issue has paid to the
Corporation the amount of such tax or has established, to the satisfaction of
the Corporation, that such tax has been paid.

                Notwithstanding anything to the contrary herein, before taking 
any action that would cause an adjustment reducing the conversion rate or before
any such adjustment is made as a result of a Reset Event, in either event, such 
that the effective conversion price (for all purposes an amount equal to $100.00
divided by the conversion rate as in effect at such time) would be below the 
then par value of the Common Stock, the Corporation shall take any corporate 
action which may, in the opinion of its counsel, be necessary in order that the 
Corporation may validly and legally issue fully paid and nonassessable shares of
Common Stock at the conversion rate as so adjusted.

                (g)     Prior Notice of Certain Events. In case:
                        ------------------------------

                (i)     the Corporation shall declare any dividend (or any other
distribution) on its Common Stock; or

                (ii)    the Corporation shall authorize the granting to the 
holders of Common Stock of rights or warrants to subscribe for or purchase any 
shares of stock of any class or of any other rights or warrants; or

                (iii)   of any reclassification of Common Stock (other than a 
subdivision or combination of the outstanding Common Stock, or a change in par 
value, or from par value to no par value, or from no par value to par value), or
of any consolidation or merger to which the Corporation is a party and for which
approval of any stockholders of the Corporation shall be required, or of the 
sale or transfer of all or substantially all of the assets of the Corporation or
of any compulsory share exchange whereby the Common Stock is converted into 
other securities, cash or other property; or



                                       8
<PAGE>
 
         (iv)   of the voluntary or involuntary dissolution, liquidation or
winding up of the Corporation;

then the Corporation shall cause to be filed with the transfer agent for the 
Series A Convertible Preferred Stock, and shall cause to be mailed to the 
holders of record of the Series A Convertible Preferred Stock, at their last 
addresses as they shall appear upon the stock transfer books of the Corporation,
at least 10 days prior to the applicable record date hereinafter specified, a 
notice stating (x) the date on which a record (if any) is to be taken for the 
purpose of such dividend, distribution or granting of rights or warrants or, if 
a record is not to be taken, the date as of which the holders of Common Stock of
record to be entitled to such dividend, distribution, rights or warrants are to 
be determined and a  description of the cash, securities or other property to be
received by such holders upon such dividend, distribution or granting of rights 
or warrants or (y) the date on which such reclassification, consolidation, 
merger, sale, transfer, share exchange, dissolution, liquidation or winding up 
is expected to become effective, the date as of which it is expected that 
holders of Common Stock of record shall be entitled to exchange their shares of 
Common Stock for securities or other property deliverable upon such exchange, 
dissolution, liquidation or winding up and the consideration, including 
securities or other property, to be received by such holders upon such exchange;
provided, however, that no failure to mail such notice or any defect therein or 
in the mailing thereof shall affect the validity of the corporate action 
required to be specified in such notice.

         (h)    Other Changes in Conversion Rate.  The Corporation from time to 
                --------------------------------
time may increase the conversion rate by any amount for any period of time if
the period is at least 20 days and if the increase is irrevocable during the
period. Whenever the conversion rate is so increased, the Corporation shall mail
to holders of record of the Series A Convertible Preferred Stock a notice of the
increase at least 10 days before the date the increased conversion rate takes
effect, and such notice shall state the increased conversion rate and the period
it will be in effect.

         The Corporation may make such increases in the conversion rate, in 
addition to those required or allowed by this Section 4, as shall be determined 
by it, as evidence by a resolution of the Board of Directors, to be advisable in
order to  avoid or diminish any income tax to holders of Common Stock resulting 
from any dividend or distribution of stock or issuance or rights or warrants to 
purchase or subscribe for stock or from any event treated as such for income tax
purposes.

         (i)    Ambiguities/Errors. The Board of Directors of the Corporation 
                ------------------
shall have the power to resolve any ambiguity or correct any error in the 
provisions relating to the convertibility of the Series A Convertible Preferred 
Stock, and its actions in so doing shall be final and conclusive.

         5.     Mandatory Conversion at Option of Corporation. At any time on or
                ---------------------------------------------
after the Reset Date, the Corporation, as its option, may cause the Series A 
Convertible Preferred Stock to be converted in whole, or in part, on a pro rata 
                                                                       --- ----
basis, into fully paid and nonassessable shares of Common Stock and such other 
securities and property as herein provided if the closing price of the Common 
Stock shall have exceeded 150% of the then applicable conversion price for at
least 20 trading days in any 30 consecutive trading day period. Any shares of
Series A Convertible Preferred Stock so converted shall be treated as having
been surrendered by the holder thereof for conversion pursuant to Section 4 on
the date of such mandatory conversion (unless previously converted at the option
of the holder).

         No more than 60 nor less than 10 days prior to the date of any such 
mandatory conversion, notice by first class mail, postage prepaid, shall be 
given to the holders of record of the Series A Convertible Preferred Stock to be
converted, addressed to such holders at their last addresses 

                                       9

<PAGE>
 
as shown on the stock transfer books of the Corporation.  Each such notice shall
specify the date fixed for conversion, the place or places for surrender of 
shares of Series A Convertible Preferred Stock, and the then effective 
conversion rate pursuant to Section 4.

               The "closing price" for each trading day shall be the reported 
last sales price regular way or, in case no such reported sale takes place on 
such day, the average of the reported closing bid and asked prices regular way, 
in either case on the NASDAQ Small-Cap Market or the NASDAQ National Market 
System (collectively referred to as, "NASDAQ") or, if the Common Stock is not 
quoted on NASDAQ, on the principal national securities exchange on which the 
Common Stock is listed or admitted to trading (based on the aggregate dollar 
value of all securities listed or admitted to trading) or, if not listed or 
admitted to trading on any national securities exchange or quoted on NASDAQ, the
average of the closing bid and asked prices in the over-the-counter market as 
furnished by any NASD member firm selected from time to time by the Corporation 
for that purpose, or, if such prices are not available, the fair market value 
set by, or in a manner established by, the Board of Directors of the Corporation
in good faith.  "Trading day" shall have the meaning given in Section 4 hereof.

               Any notice which is mailed as herein provided shall be 
conclusively presumed to have been duly given by the Corporation on the date 
deposited in the mail, whether or not the holder of the Series A Convertible 
Preferred Stock receives such notice; and failure properly to give such notice 
by mail, or any defect in such notice, to the holders of the shares to be 
converted shall not affect the validity of the proceedings for the conversion of
any other shares of Series A Convertible Preferred Stock. On or after the date 
fixed for conversion as stated in such notice, each holder of shares called to 
be converted shall surrender the certificate evidencing such shares to the 
Corporation at the place designated in such notice for conversion.  
Notwithstanding that the certificates evidencing any shares properly called for
conversion shall not have been surrendered, the shares shall no longer be deemed
outstanding and all rights whatsoever with respect to the shares so called for 
conversion (except the right of the holders to convert such shares upon 
surrender of their certificates therefor) shall terminate.

               6.    Voting Rights.
                     -------------

               (a)   General.  Except as otherwise provided herein, in the 
                     -------
Amended and Restated Certificate of Incorporation or by law, the holders of 
shares of Series A Convertible Preferred Stock, the holders of shares of Common 
Stock and the holders of any other class or series of shares entitled to vote 
with the Common Stock shall vote together as one class on all matters submitted 
to a vote of stockholders of the Corporation.  In any such vote, each share of 
Series A Convertible Preferred Stock shall entitle the holder thereof to cast 
the number of votes equal to the number of votes which could be cast in such 
vote by a holder of the Common Stock into which such share of Series A 
Convertible Preferred Stock is convertible on the record date for such vote, or 
if no record date has been established, on the date such vote is taken.  Any 
shares of Series A Convertible Preferred Stock held by the Corporation or any 
entity controlled by the Corporation shall not have voting rights hereunder and 
shall not be counted in determining the presence of a quorum.

               (b)   Class Voting Rights.  In addition to any vote specified in
                     -------------------
paragraph (a) of this Section 6, so long as 50% of the shares of Series A 
Convertible Preferred Stock (including those shares of Series A Convertible 
Preferred Stock issued or issuable upon the exercise of the placement agent 
warrants issued in connection with the offer and sale of the Series A 
Convertible Preferred Stock) shall be outstanding, the Corporation shall not, 
without the affirmative vote or consent of the holders of at least 66-2/3% of 
all outstanding Series A Convertible Preferred Stock voting separately as a 
class, (i) amend, alter or repeal any provision of the Amended and Restated 
Certificate of Incorporation, as amended, or 

                                      10

the Bylaws of the Corporation so as adversely to affect the relative rights, 
preferences, qualifications, limitations or restrictions of the Series A 
Convertible Preferred Stock, (ii) declare any dividend or distribution on the 
Common Stock or any other class or series of preferred stock or authorize the 
repurchase of any securities of the Corporation or (iii) authorize or issue, or 
increase the authorized amount of, any additional class or series of stock, or 
any security convertible into stock of such class or series, (A) ranking prior 
to, or on a parity with, the Series A Convertible Preferred Stock upon 
liquidation, dissolution or winding up of the Corporation or a sale of all or 
substantially all of the assets of the Corporation or (B) providing for the 
payment of any dividends or distributions. A class vote on the part of the 
Series A Convertible Preferred Stock shall, without limitation, specifically not
be deemed to be required (except as otherwise required by law or resolution of 
the Corporation's Board of Directors) in connection with: (a) the authorization,
issuance or increase in the authorized amount of Common Stock or of any shares 
of any other class or series of stock ranking junior to the Series A Convertible
Preferred Stock in respect of distributions upon liquidation, dissolution or 
winding up of the Corporation; (b) the authorization, issuance or increase in 
the amount of the Series A Convertible Preferred Stock or any bonds, mortgages, 
debentures or other obligations of the Corporation (other than bonds, mortgages,
debentures or other obligations convertible into or exchangeable for or having 
option rights to purchase any shares of stock of the Corporation the 
authorization issuance or increase in amount of which would require the consent 
of the holders of the Series A Preferred Stock); or (c) any consolidation or 
merger of the Corporation with or into another corporation, a sale or transfer 
of all or part of the Corporation's assets for cash, securities or other 
property, or a compulsory share exchange.

          7.   Outstanding Shares.  For purposes of this Certificate of 
               ------------------
Designations, all shares of Series A Convertible Preferred Stock shall be deemed
outstanding except (i) from the date, or the deemed date, of surrender of 
certificates evidencing shares of Series A Convertible Preferred Stock, all 
shares of Series A Convertible Preferred Stock converted into Common Stock, (ii)
from the date of registration of transfer, all shares of Series A Convertible 
Preferred Stock held of record by the Corporation or any subsidiary of the 
Corporation and (iii) any and all shares of Series A Convertible Preferred Stock
held in escrow prior to delivery of such stock by the Corporation to the initial
beneficial owners thereof.

          8.   Status of Acquired Shares.  Shares of Series A Convertible 
               -------------------------
Preferred Stock received upon conversion pursuant to Section 4 or Section 5 or 
otherwise acquired by the Corporation will be restored to the status of 
authorized but unissued shares of Preferred Stock, without designation as to 
class, and may thereafter be issued, but not as shares of Series A Convertible 
Preferred Stock.

          9.   Preemptive Rights.  The Series A Convertible Preferred Stock is 
               -----------------
not entitled to any preemptive or subscription rights in respect of any 
securities of the Corporation.

          10.  Severability of Provisions.  Whenever possible, each provision 
               --------------------------
hereof shall be interpreted in a manner as to be effective and valid under 
applicable law, but if any provision hereof is held to be prohibited by or 
invalid under applicable law, such provision shall be ineffective only to the 
extent of such prohibition or invalidity, without invalidating or otherwise 
adversely affecting the remaining provisions hereof. If a court of competent 
jurisdiction should determine that a provision hereof would be valid or 
enforceable if a period of time were extended or shortened or a particular 
percentage were increased or decreased, then such court may make such change as 
shall be necessary to render the provision in question effective and valid under
applicable law.

                                      OF

          BOSTON LIFE SCIENCES, INC. (the "Corporation"), a corporation
organized and existing under and by virtue of the General Corporation Law of the
State of Delaware, DOES HEREBY CERTIFY:

          FIRST:  That at a meeting of the Board of Directors of the

          RESOLVED, that the Board of Directors hereby approves and recommends
     to the Company's stockholders that Article FOURTH of the Articles of

     approval at the Meeting, amended and restated in its entirety to read as
     follows:

                    "FOURTH:  The aggregate number of shares which the
          Corporation shall have authority to issue is 26,000,000 to be divided
          into (a) 25,000,000 shares of Common Stock, par value $.01 per share,

                    The Board of Directors is hereby empowered to cause the
          Preferred Stock to be issued from time to time for such consideration
          as it may from time to time fix, and to cause such Preferred Stock to

          and relative, participating, optional or other special rights, if any,
          or the qualifications, limitations or restrictions thereof, as
          designated by
<PAGE>
 
          the Board of Directors in the resolution providing for the issue of
          such series.  Shares of Preferred Stock of any one series shall be

               Effective as of 5:00 p.m., Eastern time, on June 9, 1997, all
          outstanding shares of Common Stock held by each holder of record on

          without any further action on the part of the holders thereof or this
          Corporation.  No fractional shares shall be issued.  All fractional
          shares for one-half share or more shall be increased to the next
          higher whole number of shares and all fractional shares less than one-
          half share shall be decreased to the next lower whole number of
          shares, respectively."

                                   EXHIBIT A
                                   ---------

                     Series A Convertible Preferred Stock
                     ------------------------------------


        1.  Designation and Amount.  There shall be a series of Preferred Stock 
            ----------------------
designated as "Series A Convertible Preferred Stock" and the number of shares 
constituting such series shall be 264,000.  Such series is referred to herein as
the "Series A Convertible Preferred Stock".  Such number of shares may be 
increased or decreased by resolution of the Board of Directors of the 
Corporation; provided, however, that no decrease shall reduce the number of 
shares of Series A Convertible Preferred Stock to less than the number of shares
then issued and outstanding.

        2.  Dividends.  Subject to the prior and superior rights of the holders 
            ---------
of any shares of any series of Preferred Stock ranking and superior to the 
shares of Series A Convertible Preferred Stock with respect to dividends and 
distributions, the holders of shares of Series A Convertible Preferred Stock, 
shall be entitled to receive dividends and distributions, when, as and if 
declared by the Board of Directors out of funds legally available for such 
purpose.  If the Corporation declares a dividend





                           [CONTINUED ON NEXT PAGE]

* Copy of Exhibit A to the certificate of amendment
<PAGE>
 
or distribution on the common stock, par value $.01 per share (the "Common 
Stock"), of the Corporation, the holders of shares of Series A Convertible 
Preferred Stock shall be entitled to receive for each share of Series A 
Convertible Preferred Stock a dividend or distribution in the amount of the 
dividend or distribution that would be received by a holder of the Common Stock 
into which such share of Series A Convertible Preferred Stock is convertible on 
the record date for such dividend or distribution. If the Corporation declares a
dividend or distribution on any other class or series of preferred stock, the 
holders of shares of Series A Convertible Preferred Stock shall be entitled to 
receive a dividend or distribution in an amount per share in proportion to the 
dividend or distribution declared on a share of such other class or series based
upon the liquidation preference of a share of the Series A Convertible Preferred
Stock relative to that of a share of such other class or series, unless the 
holders of at least 66-2/3% of the outstanding shares of Series A Convertible 
Preferred Stock consent otherwise. In any such case, the Corporation shall 
declare a dividend or distribution on the Series A Convertible Preferred Stock 
at the same time that it declares a dividend or distribution on the Common Stock
or such other class or series of preferred stock and shall establish the same 
record date for the dividend or distribution on the Series A Convertible 
Preferred Stock as is established for such dividend or distribution on the 
Common Stock or such other class or series of preferred stock. Each such 
dividend or distribution will be payable to holders of record of the Series A 
Convertible Preferred Stock as they appeared on the records of the Corporation 
at the close of business on the record date declared for such dividend or 
distribution, as shall be fixed by the Board of Directors. If the corporation 
declares or pays a dividend or distribution on the Series A Convertible 
Preferred Stock as a result of the declaration or payment of a dividend or 
distribution on the Common Stock or any other class or series of preferred stock
as described above, the holders of the Series A Convertible Preferred Stock 
shall not be entitled to any additional dividend or distribution solely because 
such first dividend or distribution also required the declaration or payment of 
a dividend or distribution on any other class or series of preferred stock. Any 
reference to "distribution" contained in this Section 2 shall not be deemed to 
include any distribution made in connection with any liquidation, dissolution or
winding up of the Corporation, whether voluntary or involuntary.

     3.  Liquidation Preference.  (a)  In the event of a (i) liquidation, 
         ----------------------
dissolution or winding up of the Corporation, whether voluntary or involuntary 
or (ii) a sale or other disposition of all or substantially all of the assets of
the Corporation (a "Liquidation Event"), after payment or provision for payment 
of debts and other liabilities of the Corporation, the holders of the Series A 
Convertible Preferred Stock then outstanding shall be entitled to be paid out of
the assets of the Corporation available for distribution to its shareholders, 
whether such assets are capital, surplus, or earnings, before any payment or 
declaration and setting apart for payment of any amount shall be made in respect
of the stock junior to the Series A Convertible Preferred Stock, an amount equal
to $130.00 per share plus an amount equal to all declared and unpaid dividends 
thereon. If upon any Liquidation Event, whether voluntary or involuntary, the 
assets to be distributed to holders of the Series A Convertible Preferred Stock 
shall be insufficient to permit the payment to such shareholders of the full 
preferential amounts aforesaid, then all of the assets of the Corporation to be 
distributed shall be so distributed ratably to the holders of the Series A 
Convertible Preferred Stock on the basis of the number of shares of Series A 
Convertible Preferred Stock held. A consolidation or merger of the Corporation 
with or into another corporation shall not be considered a liquidation, 
dissolution or winding up of the Corporation or a sale or other disposition of 
all or substantially all of the assets of the Corporation. All shares of Series 
A Convertible Preferred Stock shall rank as to payment upon the occurrence of 
any of the events described in clauses (i) and (ii) above senior to the Common 
Stock as provided herein and, unless the terms of such series shall provide 
otherwise, senior to all other series of the Corporation's preferred stock.

                                       2
<PAGE>
 
          (b)  After the payment or distribution to the holders of the Series A 
Preferred Stock of the full preferential amounts aforesaid, the holders of 
shares of the Common Stock and any other shares of participating preferred stock
then outstanding will be entitled to receive, pro rata an amount per share equal
                                              --- ----
to $13 plus accrued but unpaid dividends, if any, paid to the holders of the 
Series A Convertible Preferred Stock. After the payment or distribution pursuant
to the immediately preceding sentence, the holders of shares of the Series A 
Convertible Preferred Stock, the Common Stock and any other shares of 
participating preferred stock then outstanding will share any remaining assets 
of the Corporation on a pari passu, as converted basis. 
                        ---- -----

          4.   Conversion.
               ----------
 
          (a) Right of Conversion. The shares of Series A Convertible Preferred
              ------------------- 
Stock shall be convertible, in whole or in part, at the option of the holder
thereof and upon notice to the Corporation as set forth in paragraph (b) below,
into fully paid and nonassessable shares of Common Stock and such other
securities and property as hereinafter provided. The shares of Series A
Convertible Preferred Stock shall be convertible initially at the rate of
175.3771 shares of Common Stock for each full share of Series A Convertible
Preferred Stock and shall be subject to adjustment as provided herein. The
initial conversion price per share of Common Stock is $.5702 and shall be
subject to adjustment as provided herein. For purposes of this resolution, the
"conversion rate" applicable to a share of Series A Convertible Preferred Stock
shall be the number of shares of Common Stock and number or amount of any other
securities and property as hereinafter provided into which a share of Series A
Convertible Preferred Stock is then convertible and shall be determined by
dividing the then existing conversion price into $100.00.

          Subject to adjustment pursuant to the provisions of paragraph (c) 
below, in the event that the conversion price in effect at the time of each 
Interim Closing Date (as defined below) and the Final Closing Date (as defined 
below) is greater than 85% of the average closing bid price of the Common Stock 
for the thirty consecutive trading days immediately preceding (x) any interim 
closing date of the issuance and sale of the Series A Convertible Preferred
Stock (each an "Interim Closing Date") or (y) the final closing date of the
issuance and sale of the Series A Convertible Preferred Stock (the "Final
Closing Date"), then the conversion price shall be adjusted to equal the lesser
of any such average closing bid price. If there is any change in the conversion
price as a result of the preceding sentence, then the conversion rate shall be
changed accordingly, and shall be determined by dividing the new conversion
price into $100.00. The Corporation shall prepare a certificate signed by the
principal financial officer of the Corporation setting forth the conversion rate
as of the Final Closing Date, showing in reasonable detail the facts upon which
such conversion rate is based, and such certificate shall forthwith be filed
with the transfer agent of the Series A Convertible Preferred Stock.
Notwithstanding the provisions of subparagraph (vi) of paragraph (c) below, a
notice stating that the conversion rate has been adjusted pursuant to this
paragraph, or that no adjustment is necessary, and setting forth the conversion
rate in effect as of the Final Closing Date shall be mailed as promptly as
practicable after the Final Closing Date by the Corporation to all record
holders of Series A Convertible Preferred Stock at their last addresses as they
shall appear in the stock transfer books of the Corporation.

          Subject to adjustment pursuant to the provisions of paragraph (c) 
below, the conversion price in effect immediately prior to the date that is 12 
months after the Final Closing Date of the issuance and sale of the Series A 
Convertible Preferred Stock (the "Reset Date") shall be adjusted and reset 
effective as of the Reset Date if the average closing bid price of the Common 
Stock for the 30

                                       3
<PAGE>
 
consecutive trading days immediately preceding the Reset Date (the "12-Month 
Trading Price") is less than 130% of the then applicable conversion price (a 
"Reset Event"). Upon the occurrence of a Reset Event, the conversion price shall
be reduced to be equal to the greater of (A) the 12-Month Trading Price divided 
by 1.3, (B) 50% of the then applicable conversion price and (C) $.375 (subject 
to a proportional adjustment in the event of an adjustment to the conversion 
price pursuant to paragraph 4(c) below). If there is any change in the 
conversion price as a result of the preceding sentence, then the conversion rate
shall be changed accordingly, and shall be determined by dividing the new 
conversion price into $100.00. The Corporation shall prepare a certificate 
signed by the principal financial officer of the Corporation setting forth the 
conversion rate as of the Reset Date, showing in reasonable detail the facts 
upon which such conversion rate is based, and such certificate shall forthwith 
be filed with the transfer agent of the Series A Convertible Preferred Stock. 
Notwithstanding the provisions of subparagraph (vi) of paragraph (c) below, a 
notice stating that the conversion rate has been adjusted pursuant to this 
paragraph, or that no adjustment is necessary, and setting forth the conversion 
rate in effect as of the Reset Date shall be mailed as promptly as practicable 
after the Reset Date by the Corporation to all record holders of the Series A 
Convertible Preferred Stock at their last addresses as they shall appear in the 
stock transfer books of the Corporation.

          The "closing bid price" for each trading day shall be the reported 
closing bid price on the NASDAQ Small-Cap Market or the NASDAQ National Market 
System (collectively referred to as, "NASDAQ") or, if the Common Stock is not 
quoted on NASDAQ, on the principal national securities exchange on which the 
Common Stock is listed or admitted to trading (based on the aggregate dollar 
value of all securities listed or admitted to trading) or, if not listed or 
admitted to trading on any national securities exchange or quoted on NASDAQ, the
closing bid price in the over-the-counter market as furnished by any NASD member
firm selected from time to time by the Corporation for that purpose, or, if such
prices are not available, the fair market value set by, or in a manner 
established by, the Board of Directors of the Corporation in good faith. 
"Trading day" shall mean a day on which the national securities exchange or 
NASDAQ used to determine the closing bid price is open for the transaction of 
business or the reporting of trades or, if the closing bid price is not so 
determined, a day on which NASDAQ is open for the transaction of business.

          (b)   Conversion Procedures.  Any holder of shares of Series A 
                ---------------------
Convertible Preferred Stock desiring to convert such shares into Common Stock 
shall surrender the certificate or certificates evidencing such shares of Series
A Convertible Preferred Stock at the office of the transfer agent for the Series
A Convertible Preferred Stock, which certificate or certificates, if the 
Corporation shall so require, shall be duly endorsed to the Corporation or 
in blank, or accompanied by proper instruments of transfer to the Corporation or
in blank, accompanied by irrevocable written notice to the Corporation that the 
holder elects so to convert such shares of Series A Convertible Preferred Stock 
and specifying the name or names (with address) in which a certificate or 
certificates evidencing shares of Common Stock are to be issued. The Corporation
need not deem a notice of conversion to be received unless the holder complies 
with all the provisions hereof. The Corporation will instruct the transfer agent
(which may be the Corporation) to make a notation of the date that a notice of 
conversion is received, which date shall be deemed to be the date of receipt for
purposes hereof.

          The Corporation shall, as soon as practicable after such deposit of 
certificates evidencing shares of Series A Convertible Preferred Stock 
accompanied by the written notice and compliance with any other conditions
herein contained, deliver at such office of such transfer agent to the person
for whose account such share of Series A Convertible Preferred Stock were so
surrendered, or to the nominee or nominees of such person, certificates
evidencing the number of full shares of Common Stock to which such person shall
be entitled as aforesaid, together with a cash adjustment of any fraction of a

                                       4


         



<PAGE>
 
share as hereinafter provided. Subject to the following provisions of this 
paragraph, such conversion shall be deemed to have been made as of the date of 
such surrender of the shares of Series A Convertible Preferred Stock to be 
converted, and the person or persons entitled to receive the Common Stock 
deliverable upon conversion of such Series A Convertible Preferred Stock shall 
be treated for all purposes as the record holder or holders of such Common 
Stock on such date; provided, however, that the Corporation shall not be 
required to convert any shares of Series A Convertible Preferred Stock while the
stock transfer books of the Corporation are closed for any purpose, but the 
surrender of Series A Convertible Preferred Stock for conversion during any 
period while such books are so closed shall become effective for conversion 
immediately upon the reopening of such books as if the surrender had been made 
on the date of such reopening, and the conversion shall be at the conversion 
rate in effect on such date. No adjustments in respect of any dividends on 
shares surrendered for conversion or any dividend on the Common Stock issued 
upon conversion shall be made upon the conversion of any shares of Series A 
Convertible Preferred Stock.

          All notices of conversion shall be irrevocable; provided, however, 
that if the Corporation has sent notice of an event pursuant to Section 4(g) 
hereof, a holder of Series A Convertible Preferred Stock may, at its election, 
provide in its notice of conversion that the conversion of its shares of Series 
A Convertible Preferred Stock shall be contingent upon the occurrence of the 
record date or effectiveness of such event (as specified by such holder), 
provided that such notice of conversion is received by the Corporation prior to 
such record date or effective date, as the case may be.

          (c)  Certain Adjustments of Conversion Rate. In addition to adjustment
               --------------------------------------
pursuant to paragraph (a) above, the conversion rate (and the corresponding 
conversion price) shall be subject to adjustment from time to time as follows:

          (i)  In case the Corporation shall (A) pay a dividend in Common Stock 
     or make a distribution in Common Stock, (B) subdivide its outstanding 
     Common Stock, (C) combine its outstanding Common Stock into a smaller 
     number of shares of Common Stock or (D) issue by reclassification of its 
     Common Stock other securities of the Corporation, then in each such case
     the conversion rate in effect immediately prior thereto shall be adjusted
     so that the holder of any shares of Series A Convertible Preferred Stock
     thereafter surrendered for conversion shall be entitled to receive the kind
     and number of shares of Common Stock or other securities of the Corporation
     which such holder would have owned or would have been entitled to receive
     immediately after the happening of any of the events described above had
     such shares of Series A Convertible Preferred Stock been converted
     immediately prior to the happening of such event or any record date with
     respect thereto. Any adjustment made pursuant to this subparagraph (i)
     shall become effective immediately after the effective date of such event
     retroactive to the record date, if any, for such event.

          (ii)  In case the Corporation shall issue or sell Common Stock or 
     rights, options, warrants or other securities convertible into Common 
     Stock, excluding those rights, options, warrants or other securities 
     convertible into Common Stock already outstanding and disclosed in the 
     Offering Memorandum, at a price per share which is lower than both (A) the 
     then effective conversion price and (B) the closing bid price (as defined 
     in Section 4) for the trading day immediately prior to such record date 
     (the "Current Market Price"), then the conversion rate shall be determined 
     by multiplying the conversion rate theretofore in effect by a fraction, of 
     which the numerator shall be the number of shares of Common Stock 
     outstanding immediately prior to the issuance of such shares, rights, 
     options, warrants or convertible securities plus the number of additional
     shares of Common Stock offered for subscription or purchase, and of which
     the

                                       5

<PAGE>
 
denominator shall be the number of shares of Common Stock outstanding 
immediately prior to the issuance of such rights, options, warrants or 
convertible securities plus the number of shares which the aggregate offering 
price of the total number of shares offered would purchase at the then effective
conversion price. Such adjustment shall be made whenever such rights, options, 
warrants or convertible securities are issued, and shall become effective 
immediately and retroactive to the record date for the determination of 
stockholders entitled to receive such rights, options, warrants or convertible 
securities.

     (iii)  In case the Corporation shall distribute to all or substantially all
holders of its Common Stock evidences of its indebtedness or assets (excluding 
cash dividends or distributions out of earnings) or rights, options, warrants or
convertible securities containing the right to subscribe for or purchase Common 
Stock (excluding those referred to in subparagraph (ii) above), then in each 
case the conversion rate shall be determined by multiplying the conversion rate 
theretofore in effect by a fraction, of which the numerator shall be the then 
fair value as determined in good faith by the Corporation's Board of Directors 
on the date of such distribution, and of which the denominator shall be such 
fair value on such date minus the then fair value (as so determined) of the 
portion of the assets or evidences of indebtedness so distributed or of such 
subscription rights, options, warrants or convertible securities applicable to 
one share. Such adjustment shall be made whenever any such distribution is made 
and shall become effective on the date of distribution retroactive to the record
date for the determination of stockholders entitled to receive such 
distribution.

     (iv)   Upon the expiration of any rights, options, warrants or conversion 
privileges, if such shall not have been exercised, the conversion rate shall, 
upon such expiration, be readjusted and shall thereafter be such as it would 
have been had it been originally adjusted (or had the original adjustment not 
been required, as the case may be) on the basis of (A) the fact that Common 
Stock, if any, actually issued or sold upon the exercise of such rights, 
options, warrants or conversion privileges, and (B) the fact that such shares of
Common Stock, if any, were issued or sold for the consideration actually 
received by the Corporation upon such exercise plus the consideration, if any, 
actually received by the Corporation for the issuance, sale or grant of all such
rights, options, warrants or conversion privileges whether or not exercised.

     (v)    No adjustment in the conversion rate shall be required unless such 
adjustment would require an increase or decrease of at least 1% in such rate; 
provided, however, that the Corporation may make any such adjustment at its 
election; and provided, further, that any adjustments which by reason of this 
subparagraph (v) are not required to be made shall be carried forward and taken 
into account in any subsequent adjustment. All calculations under this Section 4
shall be made to the nearest cent or to the nearest one-hundredth of a share, as
the case may be.

     (vi)   Whenever the conversion rate is adjusted as provided in any 
provision of this Section 4;

            (A)  the Corporation shall compute (or may retain a firm of
     independent public accountants of recognized national standing (which may
     be any such firm regularly employed by the Corporation) to compute) the
     adjusted conversion rate in accordance with this Section 4 and shall
     prepare a certificate signed by the principal financial officer of the
     Corporation (or cause any such independent public accountants to execute a
     certificate) setting forth the adjusted conversion rate and showing in
     reasonable detail the

                                       6
<PAGE>
 
           facts upon which each adjustment is based, and such certificate shall
           forthwith be filed with the transfer agent of the Series A
           Convertible Preferred Stock; and

                 (B)   a notice stating that the conversion rate has been 
           adjusted and setting forth the adjusted conversion rate shall
           forthwith be required, and as soon as practicable after it is
           required, such notice shall be mailed by the Corporation to all
           record holders of Series A Convertible Preferred Stock at their last
           addresses as they shall appear in the stock transfer books of the
           Corporation.

           (vii) In the event that at any time, as a result of any adjustment 
     made pursuant to this Section 4, the holder of any shares of Series A
     Convertible Preferred Stock thereafter surrendered for conversion shall
     become entitled to receive any shares of the Corporation other than shares
     of Common stock or to receive any other securities, the number of such
     other shares or securities so receivable upon conversion of any share of
     Series A Convertible Preferred Stock shall be subject to adjustment from
     time to time in a manner and on terms as nearly equivalent as practicable
     to the provisions contained in this Section 4 with respect to the Common
     Stock.

           (d)   No fractional Shares.  No fractional shares or scrip 
                 --------------------
representing fractional shares of Common stock shall be issued upon conversion 
of Series A Convertible Preferred Stock.  If more than one certificate 
evidencing shares of Series A Convertible Preferred Stock shall be surrendered 
for conversion at one time by the same holder, the number of full shares 
issuable upon conversion thereof shall be computed on the basis of the aggregate
number of shares of Series A Convertible Preferred Stock so surrendered.  
Instead of any fractional share of Common stock which would otherwise be 
issuable upon conversion of any shares of Series A Convertible Preferred Stock, 
the Corporation shall pay a cash adjustment in respect of such fractional 
interest in an amount equal to the same fraction of the market price per share 
of Common Stock (which shall be the closing price as defined in Section 5) at 
the close of business on the day of conversion.

           (e)   Consolidation; Merger; Etc.  If the Corporation shall enter 
                 --------------------------
into any consolidation, merger, combination or other transaction in which shares
of Common Stock constituting in excess of 50% of the voting power of the
Corporation are exchanged for or changed into other stock or securities, cash
and/or any other property (a "Merger Transaction"), then in any such case the
shares of Series A Convertible Preferred Stock shall at the same time be
similarly exchanged or changed in an amount per share equal to (i) the
conversion rate in effect at such time multiplied by (ii) the aggregate fair
market value, as determined in good faith by the Board of Directors of the
Corporation, of stock, securities, cash and/or any other property (payable in
kind), as the case may be, into which or for which each share of Common stock is
changed or exchanged (the "Per Share Merger Consideration"); provided, however,
                                                             --------  -------
that if any stock of securities received in the Merger Transaction are traded on
a securities exchange or quotation system, the fair market value of such stock
or securities shall be the closing sales price of such stock or securities as
reported by the principal exchange or quotation system for such stock or
securities the business day immediately preceding the execution of the merger
agreement or other transaction agreement for such Merger Transaction, and if no
such trading market exists for such stock or securities, the aggregate fair
market value shall be as determined in good faith by the Board of Directors of
the Corporation; provided, further, however, that if any such Merger Transaction
                 --------  -------  -------
is effected on or before the Reset Date, and if the Per Share Merger
Consideration (assuming conversion of all outstanding convertible stock,
including the Series A Convertible Preferred Stock, at the conversion rate for
such stock in effect at the time of the execution and delivery of the merger
agreement relating to such Merger Transaction) is less than 130% of the then
applicable conversion price relating to the Series A Convertible Preferred
Stock, then the conversion price will be reduced to equal the greater of (x) the
Per Share

                                       7
<PAGE>
 
Merger Consideration divided by 1.3, (y) 50% of the then applicable conversion 
price and (z) $.375 (subject to a proportional adjustment in the event of an 
adjustment to the conversion price pursuant to paragraph 4(c) above).

                (f)     Reservation of Shares; Transfer Taxes; Etc.  The 
                        ------------------------------------------
Corporation shall at all times reserve and keep available, out of its authorized
unissued stock, solely for the purpose of effecting the conversion of the Series
A Convertible Preferred Stock, such number of shares of its Common Stock free of
preemptive rights as shall from time to time be sufficient to effect the 
conversion of all shares of Series A Convertible Preferred Stock from time to 
time outstanding.  The Corporation shall use its best efforts from time to time,
in accordance with the laws of the State of Delaware, to increase the authorized
number of shares of Common Stock if at any time the number of shares of Common 
Stock not outstanding shall not be sufficient to permit the conversion of all 
the then-outstanding shares of Series A Convertible Preferred Stock.

                The Corporation shall pay any and all issue or other taxes that
may be payable in respect of any issue or delivery of shares of Common Stock on
conversion of the Series A Convertible Preferred Stock. The Corporation shall
not, however, be required to pay any tax which may be payable in respect of any
transfer involved in the issue or delivery of Common Stock (or other securities
or assets) in a name other than that in which the shares of Series A Convertible
Preferred Stock so converted were registered, and no such issue or delivery
shall be made unless and until the person requesting such issue has paid to the
Corporation the amount of such tax or has established, to the satisfaction of
the Corporation, that such tax has been paid.

                Notwithstanding anything to the contrary herein, before taking 
any action that would cause an adjustment reducing the conversion rate or before
any such adjustment is made as a result of a Reset Event, in either event, such 
that the effective conversion price (for all purposes an amount equal to $100.00
divided by the conversion rate as in effect at such time) would be below the 
then par value of the Common Stock, the Corporation shall take any corporate 
action which may, in the opinion of its counsel, be necessary in order that the 
Corporation may validly and legally issue fully paid and nonassessable shares of
Common Stock at the conversion rate as so adjusted.

                (g)     Prior Notice of Certain Events. In case:
                        ------------------------------

                (i)     the Corporation shall declare any dividend (or any other
distribution) on its Common Stock; or

                (ii)    the Corporation shall authorize the granting to the 
holders of Common Stock of rights or warrants to subscribe for or purchase any 
shares of stock of any class or of any other rights or warrants; or

                (iii)   of any reclassification of Common Stock (other than a 
subdivision or combination of the outstanding Common Stock, or a change in par 
value, or from par value to no par value, or from no par value to par value), or
of any consolidation or merger to which the Corporation is a party and for which
approval of any stockholders of the Corporation shall be required, or of the 
sale or transfer of all or substantially all of the assets of the Corporation or
of any compulsory share exchange whereby the Common Stock is converted into 
other securities, cash or other property; or



                                       8
<PAGE>
 
         (iv)   of the voluntary or involuntary dissolution, liquidation or
winding up of the Corporation;

then the Corporation shall cause to be filed with the transfer agent for the 
Series A Convertible Preferred Stock, and shall cause to be mailed to the 
holders of record of the Series A Convertible Preferred Stock, at their last 
addresses as they shall appear upon the stock transfer books of the Corporation,
at least 10 days prior to the applicable record date hereinafter specified, a 
notice stating (x) the date on which a record (if any) is to be taken for the 
purpose of such dividend, distribution or granting of rights or warrants or, if 
a record is not to be taken, the date as of which the holders of Common Stock of
record to be entitled to such dividend, distribution, rights or warrants are to 
be determined and a  description of the cash, securities or other property to be
received by such holders upon such dividend, distribution or granting of rights 
or warrants or (y) the date on which such reclassification, consolidation, 
merger, sale, transfer, share exchange, dissolution, liquidation or winding up 
is expected to become effective, the date as of which it is expected that 
holders of Common Stock of record shall be entitled to exchange their shares of 
Common Stock for securities or other property deliverable upon such exchange, 
dissolution, liquidation or winding up and the consideration, including 
securities or other property, to be received by such holders upon such exchange;
provided, however, that no failure to mail such notice or any defect therein or 
in the mailing thereof shall affect the validity of the corporate action 
required to be specified in such notice.

         (h)    Other Changes in Conversion Rate.  The Corporation from time to 
                --------------------------------
time may increase the conversion rate by any amount for any period of time if
the period is at least 20 days and if the increase is irrevocable during the
period. Whenever the conversion rate is so increased, the Corporation shall mail
to holders of record of the Series A Convertible Preferred Stock a notice of the
increase at least 10 days before the date the increased conversion rate takes
effect, and such notice shall state the increased conversion rate and the period
it will be in effect.

         The Corporation may make such increases in the conversion rate, in 
addition to those required or allowed by this Section 4, as shall be determined 
by it, as evidence by a resolution of the Board of Directors, to be advisable in
order to  avoid or diminish any income tax to holders of Common Stock resulting 
from any dividend or distribution of stock or issuance or rights or warrants to 
purchase or subscribe for stock or from any event treated as such for income tax
purposes.

         (i)    Ambiguities/Errors. The Board of Directors of the Corporation 
                ------------------
shall have the power to resolve any ambiguity or correct any error in the 
provisions relating to the convertibility of the Series A Convertible Preferred 
Stock, and its actions in so doing shall be final and conclusive.

         5.     Mandatory Conversion at Option of Corporation. At any time on or
                ---------------------------------------------
after the Reset Date, the Corporation, as its option, may cause the Series A 
Convertible Preferred Stock to be converted in whole, or in part, on a pro rata 
                                                                       --- ----
basis, into fully paid and nonassessable shares of Common Stock and such other 
securities and property as herein provided if the closing price of the Common 
Stock shall have exceeded 150% of the then applicable conversion price for at
least 20 trading days in any 30 consecutive trading day period. Any shares of
Series A Convertible Preferred Stock so converted shall be treated as having
been surrendered by the holder thereof for conversion pursuant to Section 4 on
the date of such mandatory conversion (unless previously converted at the option
of the holder).

         No more than 60 nor less than 10 days prior to the date of any such 
mandatory conversion, notice by first class mail, postage prepaid, shall be 
given to the holders of record of the Series A Convertible Preferred Stock to be
converted, addressed to such holders at their last addresses 

                                       9

<PAGE>
 
as shown on the stock transfer books of the Corporation.  Each such notice shall
specify the date fixed for conversion, the place or places for surrender of 
shares of Series A Convertible Preferred Stock, and the then effective 
conversion rate pursuant to Section 4.

               The "closing price" for each trading day shall be the reported 
last sales price regular way or, in case no such reported sale takes place on 
such day, the average of the reported closing bid and asked prices regular way, 
in either case on the NASDAQ Small-Cap Market or the NASDAQ National Market 
System (collectively referred to as, "NASDAQ") or, if the Common Stock is not 
quoted on NASDAQ, on the principal national securities exchange on which the 
Common Stock is listed or admitted to trading (based on the aggregate dollar 
value of all securities listed or admitted to trading) or, if not listed or 
admitted to trading on any national securities exchange or quoted on NASDAQ, the
average of the closing bid and asked prices in the over-the-counter market as 
furnished by any NASD member firm selected from time to time by the Corporation 
for that purpose, or, if such prices are not available, the fair market value 
set by, or in a manner established by, the Board of Directors of the Corporation
in good faith.  "Trading day" shall have the meaning given in Section 4 hereof.

               Any notice which is mailed as herein provided shall be 
conclusively presumed to have been duly given by the Corporation on the date 
deposited in the mail, whether or not the holder of the Series A Convertible 
Preferred Stock receives such notice; and failure properly to give such notice 
by mail, or any defect in such notice, to the holders of the shares to be 
converted shall not affect the validity of the proceedings for the conversion of
any other shares of Series A Convertible Preferred Stock. On or after the date 
fixed for conversion as stated in such notice, each holder of shares called to 
be converted shall surrender the certificate evidencing such shares to the 
Corporation at the place designated in such notice for conversion.  
Notwithstanding that the certificates evidencing any shares properly called for
conversion shall not have been surrendered, the shares shall no longer be deemed
outstanding and all rights whatsoever with respect to the shares so called for 
conversion (except the right of the holders to convert such shares upon 
surrender of their certificates therefor) shall terminate.

               6.    Voting Rights.
                     -------------

               (a)   General.  Except as otherwise provided herein, in the 
                     -------
Amended and Restated Certificate of Incorporation or by law, the holders of 
shares of Series A Convertible Preferred Stock, the holders of shares of Common 
Stock and the holders of any other class or series of shares entitled to vote 
with the Common Stock shall vote together as one class on all matters submitted 
to a vote of stockholders of the Corporation.  In any such vote, each share of 
Series A Convertible Preferred Stock shall entitle the holder thereof to cast 
the number of votes equal to the number of votes which could be cast in such 
vote by a holder of the Common Stock into which such share of Series A 
Convertible Preferred Stock is convertible on the record date for such vote, or 
if no record date has been established, on the date such vote is taken.  Any 
shares of Series A Convertible Preferred Stock held by the Corporation or any 
entity controlled by the Corporation shall not have voting rights hereunder and 
shall not be counted in determining the presence of a quorum.

               (b)   Class Voting Rights.  In addition to any vote specified in
                     -------------------
paragraph (a) of this Section 6, so long as 50% of the shares of Series A 
Convertible Preferred Stock (including those shares of Series A Convertible 
Preferred Stock issued or issuable upon the exercise of the placement agent 
warrants issued in connection with the offer and sale of the Series A 
Convertible Preferred Stock) shall be outstanding, the Corporation shall not, 
without the affirmative vote or consent of the holders of at least 66-2/3% of 
all outstanding Series A Convertible Preferred Stock voting separately as a 
class, (i) amend, alter or repeal any provision of the Amended and Restated 
Certificate of Incorporation, as amended, or 

                                      10

the Bylaws of the Corporation so as adversely to affect the relative rights, 
preferences, qualifications, limitations or restrictions of the Series A 
Convertible Preferred Stock, (ii) declare any dividend or distribution on the 
Common Stock or any other class or series of preferred stock or authorize the 
repurchase of any securities of the Corporation or (iii) authorize or issue, or 
increase the authorized amount of, any additional class or series of stock, or 
any security convertible into stock of such class or series, (A) ranking prior 
to, or on a parity with, the Series A Convertible Preferred Stock upon 
liquidation, dissolution or winding up of the Corporation or a sale of all or 
substantially all of the assets of the Corporation or (B) providing for the 
payment of any dividends or distributions. A class vote on the part of the 
Series A Convertible Preferred Stock shall, without limitation, specifically not
be deemed to be required (except as otherwise required by law or resolution of 
the Corporation's Board of Directors) in connection with: (a) the authorization,
issuance or increase in the authorized amount of Common Stock or of any shares 
of any other class or series of stock ranking junior to the Series A Convertible
Preferred Stock in respect of distributions upon liquidation, dissolution or 
winding up of the Corporation; (b) the authorization, issuance or increase in 
the amount of the Series A Convertible Preferred Stock or any bonds, mortgages, 
debentures or other obligations of the Corporation (other than bonds, mortgages,
debentures or other obligations convertible into or exchangeable for or having 
option rights to purchase any shares of stock of the Corporation the 
authorization issuance or increase in amount of which would require the consent 
of the holders of the Series A Preferred Stock); or (c) any consolidation or 
merger of the Corporation with or into another corporation, a sale or transfer 
of all or part of the Corporation's assets for cash, securities or other 
property, or a compulsory share exchange.

          7.   Outstanding Shares.  For purposes of this Certificate of 
               ------------------
Designations, all shares of Series A Convertible Preferred Stock shall be deemed
outstanding except (i) from the date, or the deemed date, of surrender of 
certificates evidencing shares of Series A Convertible Preferred Stock, all 
shares of Series A Convertible Preferred Stock converted into Common Stock, (ii)
from the date of registration of transfer, all shares of Series A Convertible 
Preferred Stock held of record by the Corporation or any subsidiary of the 
Corporation and (iii) any and all shares of Series A Convertible Preferred Stock
held in escrow prior to delivery of such stock by the Corporation to the initial
beneficial owners thereof.

          8.   Status of Acquired Shares.  Shares of Series A Convertible 
               -------------------------
Preferred Stock received upon conversion pursuant to Section 4 or Section 5 or 
otherwise acquired by the Corporation will be restored to the status of 
authorized but unissued shares of Preferred Stock, without designation as to 
class, and may thereafter be issued, but not as shares of Series A Convertible 
Preferred Stock.

          9.   Preemptive Rights.  The Series A Convertible Preferred Stock is 
               -----------------
not entitled to any preemptive or subscription rights in respect of any 
securities of the Corporation.

          10.  Severability of Provisions.  Whenever possible, each provision 
               --------------------------
hereof shall be interpreted in a manner as to be effective and valid under 
applicable law, but if any provision hereof is held to be prohibited by or 
invalid under applicable law, such provision shall be ineffective only to the 
extent of such prohibition or invalidity, without invalidating or otherwise 
adversely affecting the remaining provisions hereof. If a court of competent 
jurisdiction should determine that a provision hereof would be valid or 
enforceable if a period of time were extended or shortened or a particular 
percentage were increased or decreased, then such court may make such change as 
shall be necessary to render the provision in question effective and valid under
applicable law.
