ITEM 1.  DESCRIPTION OF BUSINESS

GENERAL

         Sheffield  Medical  Technologies,  Inc. (the "Company") is a healthcare
company involved in the development of therapies,  delivery systems and devices.
The Company is in the development stage and as such has been principally engaged
in licensing and research and  development of certain  biomedical  technologies.
Under sponsored research agreements with independent companies, universities and
other  institutions   ("Sponsored  Research  Agreements"),   the  Company  funds
pharmaceutical, biomedical and medical research and clinical testing in exchange
for license rights to  commercialize  resulting  products and  technologies.  By
utilizing  third  party  development  and  distribution  resources,  the Company
believes that it can effectively avoid the substantial fixed costs traditionally
associated with in-house research, development, production and distribution.

         The  Company  does not intend to  manufacture  or market its  products.
Instead,  the Company intends to finance research  projects in consideration for
license rights. Thereafter, the Company will attempt to enter into manufacturing
and  marketing   agreements   with  one  or  more   established   biomedical  or
pharmaceutical companies for any products which are developed.

         The  Company  was  originally  formed  in 1986 as  Sheffield  Strategic
Metals,  Inc.,  a  Canadian  company,  to  engage  in  mineral  exploration  and
development.  It conducted no significant  business  activities  from 1986 until
late 1991. The Company commenced its biotechnology business in the United States
in  January  1992 under new  management  and  became  domesticated  as a Wyoming
Corporation in May 1992. The Company became a Delaware  corporation in June 1995
through  its merger with and into a  wholly-owned  Delaware  subsidiary.  U-Tech
Medical Corporation ("U-Tech") and Ion Pharmaceuticals, Inc. ("Ion") were formed
as wholly-owned  subsidiaries of the Company on January 13, 1992 and January 10,
1996,  respectively.  Unless the context requires  otherwise,  references to the
"Company" herein are references to Sheffield  Medical  Technologies Inc. and its
subsidiaries, Ion and U-Tech.

         The Company's  headquarters are located at 30 Rockefeller  Plaza, Suite
4515, New York, New York 10112, and its telephone number is (212) 957-6600.

BUSINESS STRATEGY

         COMMERCIALIZATION OF MEDICAL TECHNOLOGIES

         The  Company  acquires  the  rights to and  develops  technologies  for
commercialization.  The Company's strategy is to convert  intellectual  property
rights for  compounds  and devices into  marketable  products by  licensing  and
managing effective commercialization, rather than by replicating the development
laboratories and sales forces of the mainstream  industry.  The Company competes
in  three  of  the  leading   areas  of  potential   value   generation  in  the
pharmaceutical  industry today:  (i) supporting high  technology,  (ii) bringing
patient  satisfying  innovative drugs to market and (iii) developing medical and
diagnostic  devices to improve patient care. If  Company-sponsored  research and
clinical  testing are successful,  the Company intends to enter into sublicense,
joint venture or other collaborative agreements with one or more pharmaceutical,
biomedical  or medical  companies  to pursue  later phase  clinical  testing and
product  manufacturing  and marketing.  By utilizing third party development and
distribution  resources,  the Company believes that it can effectively avoid the
substantial  fixed  costs  traditionally   associated  with  in-house  research,
development, production and distribution.

         The Company is developing a group of  diversified  technologies  having
markedly  different  time horizons to potential  commercialization.  The Company
believes that this product  portfolio  approach  diminishes  some of the risk of
investing in single-product biotech,  pharmaceutical or device companies.  Since
the Company  neither invests in laboratory  facilities nor in salaried  research
workers,  it has reduced  vulnerability and increased  flexibility to enter into
technology development programs and exit such programs through a variety of exit
strategies.  By  investing  only in direct  development  costs,  the Company can
immediately  divest  itself of any program with reduced  financial  consequences
upon indications that such program is not meeting planned milestones.

<PAGE>
         IDENTIFICATION OF RESEARCH PROJECTS

         The Company identifies and conducts due diligence regarding new medical
technologies and thereafter assists in the management of research,  development,
marketing,   commercialization   and  patent  prosecution  of  technologies  and
products.  The Company's  management has substantial  experience in the areas of
technology transfer,  licensing,  product acquisition and intellectual  property
protection  and   management.   Additionally,   the  Company's   management  has
established  relationships with certain  pharmaceutical,  biomedical and medical
companies and universities and medical schools.

         RESEARCH AND DEVELOPMENT

         The Company  conducts  its  research and  development  under  Sponsored
Research  Agreements with  universities and other research  institutions.  Under
these  agreements,  the Company finances the research and development costs of a
project in return for a  percentage  of the  revenues  which may result from the
commercial  sale of resulting  products,  if any.  Through this  arrangement the
Company believes that it saves  significant fixed costs associated with research
and  development,  such as facilities  and full-time  personnel,  which it would
incur if it attempted to independently develop products. The Company manages the
preparation and submission of IND's  (Investigational New Drug Applications) and
NDA's  (New  Drug  Applications)  and  protocols  to  the  U.S.  Food  and  Drug
Administration  (the "FDA"),  monitors the approval process of such notification
and applications and conducts the initial  assessment of commercial  markets for
developed products.

         TECHNOLOGY TRANSFER

         The Company  believes that its  management  strength is in bridging the
gap between research and commercial markets for developed  products.  Therefore,
management's  principal  focus is on  technology  transfer  and  licensing.  The
Company  endeavors  to  identify  viable  research  projects  and  to  negotiate
financing at the appropriate  stage of such projects.  In addition,  the Company
will analyze and attempt to identify the appropriate stage to sell or sublicense
the technology related to such projects in order to maximize the economic return
to the Company.  The Company  does not intend to establish an in-house  research
staff or to  construct  or operate  manufacturing  or  distribution  facilities.
Instead,  the Company's  strategy is to finance  existing  research  projects in
return  for  a  license  agreement,   sublicense  agreement,  royalty  or  other
arrangement  whereby it  acquires  proprietary  rights to the  technologies  and
products  developed  in such  projects.  At an  appropriate  stage,  the Company
anticipates that it will sell, sublicense or enter into a joint venture or other
collaborative  agreement with a pharmaceutical  or other biomedical  company for
the manufacture and marketing of the Company's products.

         ALLOCATION OF RESOURCES

         The Company has utilized and will continue to utilize the proceeds from
the sales of its securities and, ultimately, will use its operating revenues, to
finance  research  and  development  of specific  projects.  If its  research is
successful,  the Company may continue to finance the project through  subsequent
stages or,  depending  on market,  financial  and other  considerations,  it may
attempt to enter into a collaborative  agreement with a third party. In the case
of unsuccessful  research projects or where  commercialization  is impossible or
impractical,  the  Company  may  terminate  such  projects  and  reallocate  its
resources to new projects. Revenues from commercialized projects will be used to
finance  additional  projects,  and the Company may attempt to raise  additional
debt or equity to finance existing or new projects.

RELATIONSHIP WITH RESEARCH INSTITUTIONS

         The Company's  success depends,  in part, on its ability to develop and
maintain  relationships  with leading research  institutions.  In addition,  the
Company  relies on principal  investigators  who are members of the faculties or
staff of  research  institutions.  Such  individuals  generally  are  subject to
policies established by their institutions regarding commercial activities.  The
Company is not aware of any conflicts  between the  activities of researchers it
sponsors and the present policies of the respective universities with which they
are associated.

PROJECTS UNDER DEVELOPMENT

RBC-CD4 ELECTROINSERTION TECHNOLOGY

         BACKGROUND. The Company is the worldwide licensee of certain technology
(the "RBC-CD4 Electroinsertion  Technology") relating to the electroinsertion of
full-length CD4 protein into red blood cells  ("RBC-CD4") for use as a potential
therapeutic in the treatment of human  immunodeficiency virus ("HIV") that leads
to Acquired Immune Deficiency Syndrome ("AIDS").  The  electroinsertion  process
inserts CD4, the protein that serves as the binding site of the HIV virus,  into
a red blood cell.  This  altered cell complex acts as a decoy and is designed to
cleanse the blood of  infection  by binding to and  removing  the HIV virus from
circulation before it can infect other cells in the human immune system.

         TECHNOLOGY.  A number of AIDS research projects have studied CD4, which
is a glycoprotein  found on the surface of T4  lymphocytes.  T4 lymphocytes  are
helper  cells  that  mediate  antigen  presentation  of the immune  system.  CD4
attaches to a glycoprotein  on the surface of HIV known as gp120.  HIV binds the
CD4  glycoprotein,  which  enables  it to  enter  the  T4  cells,  where  it can
replicate.  By this process, HIV attacks T4 cells and, as a result,  debilitates
the immune system by rendering the immune system incapable of neutralizing  HIV.
Eventually,  the number of T4 cells  decrease  and the level of HIV in the blood
increases.   This  typically   leads  to  the   development  of  AIDS  which  is
characterized  by the ultimate  collapse of the immune  system.  Once the immune
system  is  destroyed,   other  germs  and  viruses  that  ordinarily  would  be
successfully  neutralized by the immune system lead to  opportunistic  diseases.
These opportunistic diseases are ultimately the cause of death in AIDS patients.

         A number of approaches have been used in the search for a treatment for
AIDS.  Scientific  efforts have focused  principally  on the use of compounds or
vaccines with the ability to stop the  multiplication or replication of HIV. The
four  principal  compounds  that have been  approved by the FDA to date are AZT,
ddI, ddC and d4T.

         The use of CD4 as a potential  treatment for AIDS is not new.  Previous
research by many others  focused on the soluble form of CD4. This  technique has
proved ineffective because: (i) the half-life of soluble CD4 or hybrid molecules
such as CD4-IgG is short in blood  circulation;  (ii) the binding of soluble CD4
to HIV appears to tear some of the viral envelope  glycoprotein without reducing
infectivity;   and  (iii)  the  amounts  of  soluble  CD4  needed  to  establish
therapeutic concentrations are very large.

         The  Company's  RBC-CD4  Electroinsertion  Technology  differs from the
traditional focus on compounds and vaccines that inhibit the replication of HIV.
RBC-CD4 Electroinsertion  Technology has its basis in studies that indicate that
HIV will bind to red blood cells ("RBC") containing CD4 in its membrane and that
once so internalized  into the RBC, may  disintegrate.  In simplest  terms,  the
technology  focuses on incorporating  the full-length CD4 into the RBC membrane.
The  technology is intended to slow the spread of HIV in the body of an infected
patient and diminish or eliminate the  possibility of HIV infection being spread
to others by contact with the infected person,  and to help eliminate cells that
produce HIV from  circulation.  Because the technology may slow or eliminate the
advancement of HIV infection to AIDS, it is a potential therapeutic, but may not
be a cure.

         The Company's  RBC-CD4  Electroinsertion  Technology  was originated in
1987 by Dr. Y. Claude  Nicolau and other  scientists  then  associated  with The
Texas A&M University System ("TAMUS"). Dr. Nicolau is the principal investigator
for the RBC-CD4  Electroinsertion  Technology research sponsored by the Company.
RBC-CD4 Electroinsertion  Technology exposes RBC to a pulsed electric field that
allows the incorporation of certain proteins into the cell membrane.  Many types
of  proteins  can be used as  therapeutics.  Proteins  which  contain a sequence
called a "hydrophobic  membrane spanning sequence" can be attached to RBC by the
electroinsertion  technique.  The hydrophobic  membrane  spanning  sequence is a
portion of the protein that is not water soluble.  This is critical in order for
the protein to immerse  itself  into the  membrane  during the  electroinsertion
procedure.  The electroinsertion  process causes a temporary  disordering of the
cell membrane lipid bilayer. When this disordering of the membrane occurs in the
presence of a protein with a hydrophobic  sequence,  the hydrophobic  portion of
the  protein  immerses  itself into the  membrane  at the point of  disordering,
resulting in a cell with the protein inserted in the membrane.  One such protein
that  contains a  hydrophobic  sequence  is  "full-length"  CD4.  Significantly,
full-length CD4 consists of the hydrophobic portion and a soluble  extracellular
domain and a cytoplasmic domain. When the hydrophobic  sequence is deleted,  CD4
is secreted as a soluble protein which, as described  below, is the protein that
has been unsuccessful in research for the development of HIV/AIDS  therapeutics.
The  Company's  licensed  technology is for  insertion of the  potentially  more
effective  "full-length"  CD4 into red blood cells for use as a therapeutic  for
the treatment of HIV/AIDS.  In the research  funded by the Company,  Dr. Nicolau
has successfully  electroinserted  full- length CD4 into rabbit,  mouse, pig and
human red blood cell membranes to determine the affinity and binding

                                       -3-
<PAGE>
strength of the RBC-CD4 with the HIV virus.  These tests have shown that RBC-CD4
may overcome the problems  associated with soluble CD4,  including:  (i) RBC-CD4
has shown no immune  response in animals or humans;  (ii) RBC-CD4 remains in the
body for almost the normal half life span of a RBC,  which is 60 days; and (iii)
RBC-CD4 has shown a significantly  improved  binding  affinity and indicates the
capacity to inhibit HIV infection of susceptible cells.

         Because  infection  also  occurs in the lymph  nodes,  the  Company  is
developing a companion technology,  Liposome-CD4,  to address the elimination of
HIV in the  lymphatic  system.  In addition,  the Company is  developing an AIDS
Vaccine for preventing HIV infection.

         PROGRESS OF RESEARCH AND  DEVELOPMENT.  The IND and test protocols were
submitted in 1991 and were approved by the FDA in 1992.  Phase I Clinical Trials
with HIV-infected patients began in February 1992 on four patients.  Researchers
affiliated  with  TAMUS,  the  Center  for  Blood  Research  Laboratories,  Inc.
("CBRL"),  a wholly owned subsidiary of The Center for Blood Research,  Inc. (an
affiliate  of Harvard  Medical  School),  and Baylor  College  of  Medicine,  in
conjunction  with the Veterans  Affairs Medical Center,  completed these Phase I
Clinical  Trials in Houston,  Texas,  in April 1992.  The 60-day trial  included
meeting  three  criteria:  (i)  adequate  residence  time in the blood stream by
RBC-CD4 (the red blood cells into which the CD4 protein has been  inserted  that
act as the binding  site for HIV) to permit the HIV virus to bind with the cells
and  potentially be eliminated  from the  circulation;  (ii) no reduction in the
normal  functioning of the red blood cell; and (iii) no adverse immune  response
or toxicity.

         The completion of Phase I Clinical  Trials  essentially  confirmed that
there  are  no   significant   adverse   human   responses  to  the  process  at
sub-therapeutic  doses.  Results  indicated that (i) the red blood cell's normal
functioning is not altered by the electroinsertion procedure; (ii) the life span
of the  RBC-CD4 is equal to the life span of normal red blood  cells;  (iii) the
majority of the  electroinserted  CD4 remains on the red blood cell  surface for
the entire life span and little shedding of CD4 occurs, if any; and (iv) no side
effects or immune responses were observed.  The companion  studies  demonstrated
that RBC-CD4  reproducibly  inhibits the transmission of primary "wild type" HIV
strains cultured from HIV-infected patients, or cell-to-cell transmission of the
virus,  up to nearly  100  percent.  IN VITRO  studies  also have shown that the
RBC-CD4 loaded with HIV virus does not infect macrophages  during  phagocytosis,
the process of normally  removing foreign  particles and red cells at the end of
their  life span  (approximately  120  days).  Phase I  Clinical  Trials did not
confirm  anti-viral  activity  in humans,  which is the  purpose  of  additional
trials.

         The IND for Phase I/IIA Clinical Trials was submitted by the Company to
the FDA on August 18,  1994 for  approval to conduct  Phase I/II human  clinical
studies at Johns Hopkins to test the product's safety and anti-viral activity at
various doses,  and the Company  received  approval from the FDA to commence the
trial on July 17,  1995.  The Phase I/IIA  Clinical  Trial  consists of a safety
study with two  patients at the lowest dose of RBC-CD4 and a safety and activity
study with two  parts:  (1) five  patients  being  dosed  with a middle  dose of
RBC-CD4,  one of which receives placebo;  and (2) 12 patients being dosed at the
highest dose of RBC-CD4,  two of which receive placebo.  The first patient under
the Phase I/IIA  Clinical  Trials was dosed on August 8, 1995, the first patient
to be dosed with the middle dose of RBC-CD4 was dosed on November 16, 1995,  and
the  first  patient  to be dosed at the  highest  dose of  RBC-CD4  was dosed on
January 29, 1996.

         RECENT  DEVELOPMENTS  The last patient in the trial  completed the last
time point for clinical and laboratory assessment in late October 1996. All data
analyses and review has been completed and the medical and statistical report is
expected to be completed during the second quarter of 1997.

LIPOSOME-CD4 TECHNOLOGY

         BACKGROUND. The Company is the worldwide licensee of certain technology
(the  "Liposome-CD4  Technology")  relating to the incorporation of CD4 antigens
into  liposome  bilayers and their use as a potential  therapeutic  agent in the
treatment  of  HIV/AIDS.  While  RBC-CD4  Electroinsertion  Technology  is being
developed  by the  Company  to target HIV and  HIV-infected  cells in the blood,
Liposome-CD4  Technology is being developed by the Company to target  infections
in the human  lymphatic  system,  a major  reservoir  for infection not directly
reached by blood circulation.

         TECHNOLOGY.   CD4  is  a  glycoprotein  found  on  the  surface  of  T4
lymphocytes,  which are helper cells that mediate  antigen  presentation  of the
immune system.  CD4 also acts as the receptor for a glycoprotein  on the surface
of the HIV virus known as gp120. HIV binds to the CD4 glycoprotein which enables

                                       -4-
<PAGE>
the virus to enter the T4 cells where it can  replicate.  By this  process,  HIV
attacks T4 cells and debilitates the immune system, which typically leads to the
development  of AIDS.  Once the  immune  system is  destroyed,  other  germs and
viruses that would  ordinarily be successfully  neutralized by the immune system
lead to opportunistic diseases, which ultimately cause death to AIDS patients.

         Lipids  consist of two layers  (bilayers) of fatty acids  surrounded by
water;  such  bilayers are fluid and very  flexible.  Liposomes can be formed by
agitating  phospholipids  in water  suspensions  at high  frequencies  to form a
closed  vesicle  surrounded  by  a  continuous  lipid  bilayer.  Liposomes  have
properties  that are very  similar to those of natural  membranes  and have been
studied  for  carrying,  in their  interior,  specific  drugs for the purpose of
increasing  their potency and safety.  Liposomes are eventually  broken down and
metabolized by the body, or fuse with their target, at which time the content of
the liposome is  released.  The Company is  researching  the use of liposomes in
treating HIV/AIDS because the virus is not only found in the circulatory system,
but the lymphatic  system as well, which is an area that liposomes can reach. It
is believed that the lymph nodes, which are a reservoir of HIV infection,  could
be targeted for removal of HIV and HIV-infected  cells.  Liposomes inserted with
CD4  ("Liposome-CD4")  would be used in conjunction  with the Company's  RBC-CD4
Electroinsertion  Technology  which  targets  the  circulatory  system,  thereby
providing a treatment package for both the blood stream and the lymph nodes.

         The strategy of  Liposome-CD4  is to incorporate  CD4 in the bilayer of
the liposomes,  providing a specific target (I.E., HIV and  HIV-infected  cells)
for liposome fusion.  The Liposome-CD4 may also be loaded with cytotoxic agents,
or agents that will kill the target cell.  When the  free-floating  HIV comes in
contact with Liposome-CD4, the virus fuses with Liposome-CD4 and is inactivated.
The  remains of the killed  infected  T4 cell and  inactivated  virus fused with
Liposome-CD4  would then be removed by  macrophages  (white  blood  cells).  The
therapeutic  aim,  as with  RBC-CD4,  is to reduce HIV  infectivity  and slow or
eliminate the advancement of HIV infection to AIDS.

         PROGRESS  OF  RESEARCH  AND  DEVELOPMENT.  The first  milestone  of the
Liposome-CD4   research,   which  included  IN  VITRO  studies  of  Liposome-CD4
interaction  with HIV from patient (and simian  immunodeficiency  virus  ("SIV")
from M. Rhesus  monkeys)  isolate  studies  with  Liposome-CD4  encapsulating  a
cytotoxic  agent,  was  completed  in  August  1994  with the IN  VITRO  studies
demonstrating  promising anti-viral activity.  In vitro HIV inactivation results
have shown favorable  viral  inhibition  against HIV patient  isolates and a new
SHIV (hybrid virus of SIV containing the HIV envelope) isolate.

         RECENT  DEVELOPMENTS.  On July 17,  1996,  the Company  entered  into a
Sublicense  Agreement  with  SEQUUS  Pharmaceuticals,  Inc.  ("SEQUUS")  for the
continued  development and  commercialization  of the  Liposome-CD4  Technology.
Under development by SEQUUS, a clinical formulation prototype has been chosen, a
scaleable process to formulate Liposome-CD4 has been developed, CD4 from various
constructs are being produced,  and additional feasibility studies are currently
underway.

RBC-CD4  ELECTROINSERTION  AND LIPOSOME CD4  TECHNOLOGIES-COMMERCIALIZATION  AND
POTENTIAL MARKETS.

         The  World  Health  Organization  estimated  in 1996  that  there  were
approximately 26.6 million persons worldwide infected with HIV. The Pan American
Health  Organization  (the "PAHO") estimates that as of November 1996, the total
cases of AIDS reported  worldwide is 1,544,067,  the total  estimated  number of
AIDS  cases  (reported  and  not  reported)  worldwide  is 8.4  million  and the
estimated number of cases of HIV infection worldwide is 20.6 million.

         RBC-CD4  could be  administered  to HIV and AIDS  patients  either as a
typical   pharmaceutical   through  blood  transfusion   injections  or  through
autologous  transfusions  at licensed  treatment  centers.  In the first method,
recombinant   full-length   CD4  would  be   produced   on  a  large  scale  and
electroinserted  in a universal donor blood from public blood supplies.  RBC-CD4
could then be sold much like blood for  transfusions for treatment in a clinical
setting with periodic  infusions as required based on the level of viral burden.
In the second method,  the  distributor  could  decentralize  the production and
infusion through local treatment  centers.  The centers would most likely be set
up through a large medical outpatient or hospital management firm.

         Liposome-CD4  could  be  administered  to HIV  and  AIDS  patients  for
treatment in a clinical  setting with periodic  treatments as required  based on
the level of viral burden. An alternative  would be to administer  Liposome- CD4
through local treatment  centers,  perhaps at the same center that RBC-CD4 would
be administered. The centers would most likely be set up through a large medical
outpatient or hospital management firm.

HIV/AIDS VACCINE

         BACKGROUND.  The  Company  holds an  exclusive  worldwide  license to a
potential  HIV/AIDS  vaccine  (the  "HIV/AIDS  Vaccine")  and  diagnostic  under
development  at the French  Institute  of Health and Medicine  ("INSERM").  This
research  project  is  headed  by  Professor  Jean-Claude  Chermann,  one of the
original  Pasteur  Institute  discoverers of the HIV virus.  The vaccine concept
developed by Professor Chermann utilizes a portion of (beta)2 microglobulin (the
epitope),  a cellular antigen,  that is presented on the HIV viral coating after
the HIV virus has  reproduced in a human cell.  This  cellular  antigen does not
appear to vary across the various  strains of the virus and may provide a stable
target to develop  antibodies that can prevent  infection.  The Company believes
this approach may also protect against both  blood-born and sexual  transmission
of HIV. The Company's goal is to develop an oral formulation that would make the
vaccine potentially less costly and easier to distribute to a broad population.

         TECHNOLOGY.  When the HIV virus infects a cell, it replicates  and then
it buds from the  infected  cell's  surface.  A protein  which is present on the
cell's  surface then becomes  incorporated  in HIV's viral envelope as it leaves
the infected cell.  The classical  path of vaccine  development to date has been
one of raising  antibodies  against a viral  protein in an attempt to neutralize
the pathogen.  All these attempts have been largely  unsuccessful.  The HIV/AIDS
Vaccine  encompasses a new and different  approach directed toward  immunization
against HIV/AIDS. The HIV/AIDS Vaccine is designed to be different than previous
attempts  for two  basic  reasons:  (i) it would use a  cellular  versus a viral
antigenic  approach and is therefore,  common to all strains of HIV, and (ii) it
would  utilize  a  delivery   system  that  would  offer  both  humoral   (blood
transmission) and mucosal (sexual transmission)  protection, as opposed to other
vaccines now being  investigated  as  therapeutics  for preventing  cell to cell
transmission of the virus.

         PROGRESS OF RESEARCH AND DEVELOPMENT. Research has been directed toward
HIV/AIDS prevention  following isolation of the virus in 1983. Research began in
1988 in this  area  and in the use of a  cellular  antigenic  approach  directed
toward   conquering   the  disease.   Preclinical   research  has   demonstrated
neutralization  of HIV IN VITRO.  The peptide sequence that encodes this portion
of a cellular protein has been identified and sequenced and will be incorporated
in a vaccine to test for  production  of  antibodies  against the  epitope.  The
Company  plans to produce a vaccine for humans that will elicit  mucosal as well
as  humoral  immunity  and that can be  delivered  orally.  Upon the  successful
completion of pre-clinical  animal  studies,  the Company plans to submit an IND
for conducting Human Clinical Trials. The Company entered into an agreement with
an  unaffiliated  third  party  in  December  of 1995 to  develop  a  commercial
diagnostic  assay for  detection  of the  antibody.  This assay would be used in
animal and human clinical studies for the vaccine and could be sold for research
purposes  prior to receiving  approval from the FDA. Upon approval from the FDA,
the assay could be sold to physicians and clinical laboratories.  In April 1996,
researchers  published data on the isolation and  characterization  of the novel
binding  site of the  cellular  protein and  reported  that  antibodies  to this
binding site inhibited replication of several strains of HIV in VITRO studies.

         RECENT  DEVELOPMENTS.  The Company is in the final stage of development
of a  commercial  diagnostic  assay for the  detection  of the  antibody  and is
expected to commence large-scale testing in the near future.

         COMMERCIALIZATION  AND POTENTIAL MARKET.  The Company  anticipates that
the vaccine would first be used to vaccinate healthy  individuals for preventing
HIV infection.  The Company also anticipates that, long-term,  the vaccine might
be used as a therapeutic vaccine for treating the HIV infected and AIDS patients
by preventing HIV strains that replicate in the body, or additional HIV strains,
from  additionally  infecting  cells.  A commercial  market may also exist for a
diagnostic assay for detecting the monoclonal  antibody in blood for purposes of
following  progressors  and  non-progressors  who are HIV  infected,  as well as
determining the activity and usefulness of the vaccine.

         PRINCIPAL INVESTIGATOR.  Professor Jean-Claude Chermann is the inventor
of the  HIV/AIDS  Vaccine  technology  and the  principal  investigator  for the
research  sponsored by the Company.  Professor  Chermann is Research Director of
INSERM's  Research  Unit  322  for  Retroviruses  and  Associated   Diseases  in
Marseilles,  France.  Professor Chermann was previously Chief of Research at the
Pasteur  Institute  in Paris  where he  spent  25 years in  research.  Professor
Chermann, in conjunction with two other scientists, first isolated the HIV virus
in 1983 at the  Pasteur  Institute  in Paris.  In 1987 he was  awarded the Louis
Pasteur Medal. A  retrovirologist  before embarking on AIDS research,  Professor
Chermann  originally  suspected  that  AIDS was  caused by a  retrovirus.  Since
discovering  the HIV virus,  Professor  Chermann  has  devoted  his  research to
discovering  a  preventive  to the  disease,  along with a  therapeutic  to help
restore  the immune  system in  HIV-infected  patients.  Professor  Chermann  is
published widely with over 200 publications in international journals, including
publications  specific  to the  research  sponsored  by the  Company.  Professor
Chermann is a member of the Company's Scientific Advisory Board.

UGIF TECHNOLOGY - PROSTATE CANCER

         BACKGROUND.  The  Company  holds an  exclusive  worldwide  license to a
growth  regulatory  factor,  termed  Urogenital Sinus Derived Growth  Inhibitory
Factor  ("UGIF/ps20"),  which could serve as a potential prostate cancer therapy
(the "UGIF Technology").

         TECHNOLOGY.  Based on studies at Baylor College of Medicine directed at
understanding  how one  particular  tissue  type  influences  the  growth  of an
adjacent  tissue  in  the  development  of the  prostate  gland,  UGIF/ps20  was
identified.  Specifically,  UGIF/ps20  has been  isolated and purified  from rat
fetal  urogenital  sinus tissue which  differentiates  into the mature  prostate
gland  as  a  result  of   tissue-tissue   interactions.   Since  UGIF/ps20  was
demonstrated  to be  active  in human  cells,  it was  believed  that  UGIF/ps20
isolated  from  the rat  would be  essentially  identical  to  human  UGIF/ps20.
Commercial  application  and economic  feasibility of UGIF/ps20 is not dependent
upon the availability of either rat or human fetal urogenital sinus tissue,  but
rather the successful cloning, expression and testing of recombinant UGIF/ps20.

         The discovery of UGIF/ps20  indicates that urogenital sinus tissue, and
more specifically UGIF/ps20, may possibly be effective in altering the phenotype
(state of cell  differentiation)  of cells that  affect the  secretion  of newly
synthesized   proteins.   UGIF/ps20  has  shown  inhibition  of  the  growth  of
transformed  cells and tumors in culture  including  human prostate cancer cells
with non-toxic and reversible  effects.  In addition to the treatment of cancer,
there exists a potential  use of UGIF/ps20 or its  analogues in the treatment of
other diseases or conditions  dealing with  abnormalities  of the  genitourinary
system.

         PROGRESS  OF  RESEARCH  AND  DEVELOPMENT.  A  method  for  successfully
purifying  UGIF/ps20  was  identified  in April 1992 by Dr.  David R. Rowley and
biological activity of the factor was demonstrated in mice in May 1992. Research
to date has shown that UGIF/ps20  inhibits the growth of  transformed  cells and
tumors in culture  including  human  prostate  cancer cells with  non-toxic  and
reversible  effects. In addition,  in preliminary animal studies,  UGIF/ps20 has
shown an  ability to  inhibit  DNA  synthesis  and cell  proliferation  of human
prostatic  carcinoma  cells.  Results  confirmed  that  there is a human form of
UGIF/ps20 and that it is a growth factor associated with the prostate gland. The
rat and human genes for UGIF/ps20  were sequenced in late 1995. The rat gene for
UGIF/ps20 has been  incorporated  into an expression  system and recombinant rat
UGIF/ps20 is currently  being  produced.  The human gene for  UGIF/ps20 has been
incorporated  into an  expression  system and  recombinant  human  UGIF/ps20  is
currently being produced.

         RECENT DEVELOPMENTS Recombinant UGIF/ps20 is currently being tested for
verification  of its  activity  in IN  VITRO  and IN VIVO  studies.  Studies  to
determine  the  protein's  mechanism  of  action  are also  currently  underway.
Additional  animal studies will be conducted  during 1997 to determine the modes
of delivery and biological  effects of recombinant  UGIF/ps20 on prostate cancer
in "nude"  mice.  In the event that  recombinant  UGIF/ps20 is verified in these
studies,  additional  preclinical  studies with a delivery system,  and toxicity
tests, will be conducted prior to commencement of human clinical trials.

         COMMERCIALIZATION  AND POTENTIAL  MARKET.  The American  Cancer Society
estimates that  approximately  317,000 new cases of prostate  cancer occurred in
the U.S. in 1996 and that  approximately  41,400 deaths  occurred in the U.S. in
1996 from prostate cancer. As a result of the population aging,  prostate cancer
is expected to increase  significantly  over the next 15 years. Risk factors for
prostate  cancer  increase with age.  More than 80% of all prostate  cancers are
diagnosed in men over the age of 65. In addition to age, other factors regarding
the incidence of prostate  cancer  occurrence  include a higher  incidence  rate
among black Americans, familial association and dietary fat intake.

         PRINCIPAL   INVESTIGATOR.   Dr.  David  R.  Rowley  is  the   principal
investigator for the UGIF Technology project.  Dr. Rowley is Associate Professor
in the Department of Cell Biology at Baylor College of Medicine.  Dr. Rowley has
studied growth inhibitory factors, mechanism of action in tissue differentiation
and neoplastic disease, and the mechanisms of steroid hormone action in relation
to the prostate gland for over 13 years.  Dr. Rowley  received a Bachelors and a
Doctorate of Philosophy degree in Anatomy from the University of Iowa and served
as a  National  Institutes of Health  Postdoctoral  Fellow at Baylor  College of
Medicine.  He has lectured and published  numerous articles on growth inhibitory
factors, cell differentiation and receptors in the prostate gland.

MEMBRANE ATTACK COMPLEX (MAC)/COMPLEMENT TECHNOLOGY

         BACKGROUND.  The Company holds exclusive  worldwide license rights to a
certain   membrane   attack   complex   ("MAC")   complement   technology   (the
"MAC/Complement  Technology").   Through  the  Company's  funding  of  Dr.  Jose
Halperin's laboratory, scientists in Dr. Halperin's lab made certain discoveries
with regard to complement  cascade,  which  consists of a number of proteins and
regulatory  polypeptides,  and discovered  that the MAC pore opens a pathway for
the entry of high molecular weight organic compounds into cells.

         TECHNOLOGY.  The MAC/Complement  Technology consists of five complement
proteins, C5-C9, which assemble in a lipid bilayer, such as a cell membrane or a
virus  membrane,  to form a pore or a channel of  sufficient  size to allow many
molecules  and growth  factors  to pass into the cell.  If enough  channels  are
formed in the cell membrane, the cell becomes disabled and is typically lysed or
broken down and  eliminated.  The size of the pore depends in part on the number
of one of the  complement  proteins,  C9,  that form the pore.  The number of C9
protein  molecules  that form the pore is limited or  regulated  by a complement
regulatory  protein called CD59. Dr.  Halperin's lab has  demonstrated  that the
formation of MAC pores by the addition of purified complement proteins creates a
pathway for the entry of molecules of various  sizes into various cell types and
that the MAC pore can be used to load target cells with drugs or other molecules
without affecting the viability of the cell. In addition,  concentrations of the
complement  proteins needed to efficiently  load molecules into the cell via the
MAC pore have been  demonstrated to be at levels that are not toxic to the cell,
i.e. at  concentrations  that would not cause lysis of the cell.  Therefore,  by
exposing  a target  cell to MAC  channel-forming  agents  and a  therapeutic  or
diagnostic  agent,  the desired agents could be  selectively  delivered into the
target cell or cells. Therapeutic agents such as polypeptides, oligonucleotides,
toxins, antibiotics,  antivirals,  antiparasitics,  antifungals  and anti-cancer
agents could be delivered  into target cells that  otherwise are not taken up by
the  cells  or  are  inefficiently  taken  up  by  cells.  This  technology,  if
successful,  could provide for the selective  delivery of such  therapeutics  or
diagnostic agents to target cells, for example, cancer cells or viruses, without
affecting the surrounding cells that are not meant to be targeted.

         As mentioned  above, if enough MAC pores are formed in a cell membrane,
the cell becomes disabled.  Experimental  evidence indicates that this mechanism
may be involved in ridding the body of viruses, bacteria and parasites. Viruses,
bacteria or parasites may become  resistant to cell lysing by producing  CD59 on
its surface to inhibit the  formation  of MAC pores.  Since CD59  regulates  the
number of C9 molecules  that form MAC pores,  such  activity  would result in an
insufficient  amount of MAC  pores  being  formed  to create  lysis of the cell.
Consequently,  it may be possible to treat such viruses,  bacteria and parasites
by inhibiting the formation of CD59.

         PROGRESS OF RESEARCH AND DEVELOPMENT. The MAC/Complement Technology was
added to the Company's technology portfolio in late 1996, therefore, research on
this project is in early stages.  To date, the  functional  size of the MAC pore
has been determined using purified complement proteins.  Dr. Halperin's lab will
be optimizing  the MAC pore size and  attempting to load in different cell types
different functional molecules for therapeutic and/or diagnostic purposes.

         The active site of CD59 is currently being identified. The role of CD59
in protecting  viruses form complement  lysis will then need to be confirmed and
the possible  protective effect of human CD59 against complement  mediated lysis
of virus needs to be analyzed. Once these experiments are completed, the Company
will  evaluate the  possibility  of  designing  molecules to block the effect of
CD59.

         COMMERCIALIZATION AND POTENTIAL MARKET.

         The potential market for the MAC/Complement  Technology, if successful,
is substantial and includes  therapies for bacterial  diseases,  viral diseases,
hormone  deficiency  diseases,   cancer,   artherosclerosis,   arteriosclerosis,
diabetes, organ transplants,  arthritis and other immune disorders. For example,
the American  Diabetics  Association  estimates  that  approximately  14 million
people in the U.S. have diabetes and more than 650,000 people are diagnosed each
year as having  diabetes.  According  to the  American  Heart  Association,  the
estimated prevalence of artherosclerosis in 1992 was 2.28 million.

         PRINCIPAL INVESTIGATORS.  Dr. Jose A. Halperin,  Associate Professor of
the  Department  of  Medicine  at  Harvard  Medical  School,  is  the  principal
investigator  for  the  MAC/Complement  Technology  research  sponsored  by  the
Company.   Dr.  Halperin's  major  research  interests  have  been  in  membrane
transport, red cell physiology and regulation of ion pumps as they relate to the
mitogenic  effect of membrane  in  proliferative  disorders.  Dr.  Halperin  was
educated in Buenos Aires, Argentina, receiving his medical degree (CUM LAUDE) in
1972 from the  University of Buenos  Aires.  In 1983 Dr.  Halperin  received the
Annual Prize for the best work in Medical Research from

                                       -8-

Venezuela's   National  Council  for  Scientific  and   Technological   Research
(CONICIT).   Dr.  Halperin's  postdoctoral  training  includes  internships  and
residencies  in Buenos  Aires and a clinical  fellowship  at Brigham and Women's
Hospital in Boston. He joined Harvard Medical School's  Department of Physiology
in 1984.  In 1988 he was named  Instructor  in  Medicine  and in 1994  Associate
Professor of  Medicine.  In 1985 he became  associated  with Brigham and Women's
Hospital in several  capacities and presently serves as Associate  Physician for
the hospital.

ION PHARMACEUTICALS, INC. TECHNOLOGIES

         BACKGROUND.  The Company,  through its  wholly-owned  subsidiary,  Ion,
holds exclusive worldwide license rights to certain compounds and their uses for
the treatment of conditions  characterized by unregulated cell  proliferation or
cell  growth and sickle  cell  anemia and holds an  exclusive  option to license
certain  compounds  and  their  uses  for  the  treatment  of   gastrointestinal
disorders,  such as secretory  diarrhea.  Ion's intellectual  property portfolio
consists of clotrimazole  ("CLT"), its metabolites   and a number of proprietary
new chemical  entities  co-owned by Ion termed the  Trifens(TM).  Such compounds
have demonstrated  promise in therapeutic  applications for treating a number of
conditions  characterized  by  unregulated  cell  proliferation,  such as cancer
(including   multiple   drug   resistance   cases)  and  certain   proliferative
dermatological conditions, as well as sickle cell anemia and secretory diarrhea.
Ion has an ongoing collaborative program with an unaffiliated company to develop
the  Trifens(TM).  Ion acquired the Company's  rights in the  anti-proliferative
technologies at the time of Ion's  organization as a wholly-owned  subsidiary of
the Company in January 1996.

         TECHNOLOGY.  CLT,  its  metabolites,  and the  Trifens(TM)  are  active
through ion transport  modulation and may be applicable for treating,  either by
topical,  oral,  or  intravenous  administration,   a  number  of  diseases  and
conditions.  CLT is a broad spectrum  antimycotic agent used to treat pathogenic
dermatophytes, yeast infections  and topical fungal infections. Through research
conducted by Dr. Jose Halperin at Harvard Medical School, new potential uses for
these compounds have been identified  based on inhibition of cell  proliferation
or the regulation of the growth of cancer cells and other cell types,  including
the use of such  compounds  in  treating  cancer,  proliferative  dermatological
conditions,  cardiovascular disorders, such as arteriosclerotic  conditions, and
diseases caused by neovascularization, such as diabetic retinopathy. In addition
to the compounds ability to inhibit cell proliferation,  the compounds have also
been shown to inhibit the  Ca++-activated K+ channel in the human red blood cell
membrane. Dr. Carlo Brugnara at Children's Hospital in Boston has studied and is
continuing  to study the effects of such  compounds in blocking  this channel to
prevent the  dehydration  of sickled  red blood  cells.  Such an approach  could
potentially be used in the treatment of sickle cell anemia. In addition, under a
sponsored  research  and license  option  agreement  between Ion and  Children's
Hospital in Boston, Dr. Wayne Lencer is studying the effects of the compounds in
inhibiting  intestinal chloride secretion,  which is the primary transport event
of secretory diarrhea in both humans and animals.

         It is  anticipated  that CLT, its  metabolites  and/or the  Trifens(TM)
would  be  formulated  in  three  new  formulations:  an  oral  formulation,  an
intravenous or injectable formulation   and a topical formulation.  The new oral
and/or  intravenous  formulation  could  be  used  in the  study  and  potential
treatment of cancers  including  multiple drug  resistant  cancers,  sickle cell
anemia,  diarrhea   and atherosclerotic  conditions,  including restenosis after
balloon  angioplasty.  The new  topical  formulation  will be used by Ion in the
study and potential treatment of proliferative  dermatological conditions,  such
as actinic keratosis, certain cancers, such as basal cell carcinoma and Kaposi's
sarcoma and, possibly, other dermatological conditions.

         PROGRESS OF RESEARCH AND  DEVELOPMENT.  An initial human efficacy study
with a preliminary  topical  formulation of one of the parent compounds at a low
concentration  in  comparison  with a placebo  was  conducted  by the Company in
Kaposi's sarcoma patients which led to inconclusive results. Results showed that
the topical formulation was not optimized. Ion entered into an agreement with an
unaffiliated  company  to develop an  optimal  topical  formulation  at a higher
concentration  of  drug  for  use in  additional  clinical  trials  for  actinic
keratosis and Kaposi's sarcoma.

         Dr. Halperin has demonstrated  that IN VITRO  proliferation of numerous
human cancer cell lines were strongly  inhibited by one of the parent  compounds
in a dose-dependent manner. Dr. Halperin's group has also studied the effects of
one of the parent  compounds  in  experimental  models for lung  metastasis  and
squamous cell carcinoma, both resulting in favorable results.

         For the sickle cell  application,  IN VITRO  studies  performed  by Dr.
Brugnara  have  demonstrated  that  one  of the  parent  compounds  blocked  ion
transport in homozygous  sickle cells,  and studies in a transgenic  mouse model
for sickle  cells have  demonstrated  that the compound  given  orally  produced
inhibition of the red cell Gardos channel,

                                       -9-
<PAGE>
increased red cell potassium content  and decreased mean corpuscular  hemoglobin
concentration.  A pilot Phase I clinical  trial has been completed in which four
normal  subjects were given the compound  orally and the peak  inhibition of the
Gardos channel was measured. Results from the first stage of a Phase II Clinical
Trial  supported by the National  Institutes of Health and the FDA were reported
in March 1996 in which five sickle cell  anemia  patients  were given one of the
parent  compounds  orally.  The  administration  of the  compound  resulted in a
reduction of the  dehydration  and sickling of red blood cells  associated  with
sickle cell anemia.  The next phase of the ongoing Phase II clinical  trial will
assess the survival of red blood cells and hemoglobin  levels over a longer-term
period.  Ion plans to initiate  additional  laboratory  and clinical  studies to
assess the use of the Trifens(TM) in the treatment of sickle cell anemia.

         A topical formulation of one of the parent compounds has been developed
for Ion pursuant to an agreement with an  unaffiliated  company.  Clinical trial
material  has been  manufactured  under  Good  Manufacturing  Practices  ("GMP")
conditions  for use in Ion's  Phase I/II  Clinical  Trial for the  treatment  of
actinic  keratosis.  The Phase I/II Clinical Trial was initiated in July 1996 at
two clinical sites in Israel.

         RECENT DEVELOPMENTS. The actinic keratosis Phase I/II Clinical Trial is
currently  ongoing and  enrollment  was  completed  in  December  of 1996.  Upon
successful  results of this study,  Ion plans to either file an IND  application
with the FDA for  conducting a clinical  trial in the U.S. for the  treatment of
actinic  keratosis or sublicense  the  technology  for further  development  and
commercialization.

         Additional IN VITRO and animal tumor model  studies are underway,  some
of which are being conducted under contract with an unaffiliated third party, to
test the effects of the Trifens(TM) in the treatment of certain  cancers,  alone
and in combination with currently used anti-cancer drugs.

         The Company is  currently  participating  in  discussions  with certain
third  parties  regarding  the  possibility  of  partnering  or  licensing  this
technology.

         COMMERCIALIZATION  AND  MARKET  POTENTIAL.   The  American  Academy  of
Dermatology   reports  that  approximately  5  million  Americans  have  actinic
keratosis.  The American Cancer Society  estimates that there were 1,359,150 new
cases of cancer in the U.S. in 1996 and 554,740 deaths due to cancer in the U.S.
in 1996. Reuters (09-12-96)  reported that drug resistant tumors account for 40%
of all cancer cases and 90% of drug treated  cancer  patients who have undergone
chemotherapy.  The U.S.  Department of Health and Human Services  estimates that
there are over 50,000  sickle cell anemia  patients in the U.S. and according to
NDTI, the national audit source, 246,000 physician visits for sickle cell anemia
were recorded in 1995.  In addition to the market for  traveller's  diarrhea,  a
substantial market exists for treatment of infectious  diarrhea and AIDS-related
diarrhea.  The National  Institute of Diabetes and Digestive and Kidney Diseases
reports that in 1980, there were 99 million new cases of infectious  diarrhea in
the U.S.  and, in 1985,  there were 8-12  million  physician  office  visits for
infectious  diarrhea.  AIDS-related  diarrhea  occurs  in the  majority  of AIDS
patients and may be caused by drugs, viruses or bacteria.

         PRINCIPAL INVESTIGATORS.  Dr. Jose A. Halperin,  Associate Professor of
the  Department  of  Medicine  at  Harvard  Medical  School,  is  the  principal
investigator for the anti-proliferative/growth  regulatory research sponsored by
the Company.

         Dr. Carlo Brugnara, Associate Professor of Pathology at Harvard Medical
School and  Director of the  Hematology  Laboratory  at  Children's  Hospital in
Boston,  is the principal  investigator  for research related to the sickle cell
anemia  application  sponsored by the Company.  Dr.  Brugnara's  major  research
interests have been in the  determinants of cell sickling in sickle cell anemia,
membrane  transport in red blood cells, and clinical and laboratory  hematology.
Dr.  Brugnara was educated in Italy,  receiving  his medical  degree  (MAGNA CUM
LAUDE IN MEDICINE AND SURGERY) in 1979 from the  University  of Padue in Verona,
Italy. Dr. Brugnara's postdoctoral training includes internships and residencies
in Italy and with Brigham and Women's  Hospital in Boston.  He joined  Harvard's
Department of Physiology in 1983 and was named Associate Professor in 1993.

         Dr.  Wayne I. Lencer,  Assistant  Professor  of  Pediatrics  at Harvard
Medical School and Assistant  Pediatrician at Massachusetts General Hospital and
Children's Hospital in Boston, is the principal  investigator for the intestinal
diseases  research  sponsored  by  the  Company.  Dr.  Lencer's  major  research
interests  have been in the  mechanism  of vesicular  traffic in the  intestinal
epithelia,  the  mechanism  and  regulation  of salt,  water and  macromolecular
transport in the intestine, and host and pathogen interactions in the intestine.
Dr.  Lencer  received a Bachelors  degree from the  University of Michigan and a
medical degree from Boston  University  School of Medicine.  Dr. Lencer received
the Miles and  Shirley  Fitterman/American  Digestive  Health  Foundation  Basic

local  regulations.  These  regulations  and  statutes  govern the  development,
testing,  formulation,  manufacture,  labeling, storage, record keeping, quality
control,  advertising,  promotion,  sale,  distribution  and  approval  of  such
pharmaceutical  products.  Failure to comply with  applicable  requirements  can
result in fines,  recall or seizure of products,  total or partial suspension of
production,  refusal by the  government to approve  marketing of the product and
criminal prosecution.

         A new drug may not be legally marketed for commercial use in the United
States  without FDA approval.  In addition,  upon  approval,  a drug may only be
marketed  for the  indications,  in the  formulations  and at the dosage  levels
approved by the FDA.  The FDA also has the  authority  to  withdraw  approval of
drugs in accordance  with  applicable laws and  regulations.  Analogous  foreign
regulators impose similar approval requirements relating to commercial marketing
of a drug in their respective  countries and may impose similar restrictions and
limitations after approval.

         In order to obtain FDA approval of a new  product,  the Company and its
strategic partners must submit proof of safety, efficacy,  purity and stability,
and the Company must demonstrate  validation of its manufacturing  process.  The
testing and application  process is expensive and time  consuming,  often taking
several years to complete. There is no assurance that the FDA will act favorably
or quickly in reviewing such  applications.  With respect to patented  products,
processes or technologies, delays imposed or caused by the governmental approval
process may materially  reduce the period during which the Company will have the
exclusive  right to exploit them.  Such delays could also affect the  commercial
advantages  derived from proprietary  processes.  There is no assurance that the
regulatory agencies will find these submissions to be adequate.

         As part of the approval  process,  the FDA reviews the Drug Master File
(the "DMF") for a description of product chemistry and characteristics, detailed
operational  procedures for product  production,  quality  control,  process and
methods validation,  and quality assurance.  As process development continues to
mature, updates and modifications of the DMF are submitted.

         The FDA approval process for a  pharmaceutical  product includes review
of (i)  chemistry  and  formulations,  (ii)  preclinical  laboratory  and animal
studies to enable FDA approval of an IND application, (iii) initial IND clinical
studies to define safety and dose parameters,  (iv) well-controlled IND clinical
trials to demonstrate  product  efficacy and safety,  followed by submission and
FDA approval of an NDA.  Preclinical  studies involve  laboratory  evaluation of
product  characteristics and animal studies to assess the safety of the product.
Products must be formulated in accordance with GMP  requirements and preclinical
tests  must be  conducted  by  laboratories  that  comply  with FDA  regulations
governing the testing of drugs in animals.  The results of the preclinical tests
are submitted to the FDA as part of the IND  application and are reviewed by the
FDA prior to granting  the sponsor  permission  to conduct  clinical  studies in
human subjects.  Unless the FDA objects to an IND  application,  the application
will become  effective 30 days following its receipt by the FDA. There can be no
certainty that submission of an IND will result in FDA authorization to commence
clinical studies.

         Human  clinical  trials are  typically  conducted  in three  sequential
phases with some amount of overlap  allowed.  In the most basic terms, the three
phases are intended to answer the following  three questions with respect to the
product being tested:  Phase I - is it safe?;  Phase II - is it effective?;  and
Phase III - how effective is it? Phase I trials normally  consist of testing the
product in a small  number of patient  volunteers  for  establishing  safety and
pharmacokinetic  parameters using single and multiple dosing regiments. In Phase
II, the continued  safety and initial efficacy of the product are evaluated in a
somewhat larger patient population, and appropriate dosage amounts and

                                      -11-
<PAGE>
treatment  intervals are  determined.  Phase III trials  typically  involve more
definitive testing of the appropriate dose for safety ad clinical efficacy in an
expanded patient  population at multiple  clinical  testing centers.  A clinical
plan,  or   "protocol,"   accompanied   by  the  approval  of  the   institution
participating in the trials,  must be submitted to the FDA prior to commencement
of each clinical trial phase.  Each clinical  study must be conducted  under the
auspices of an Institutional Review Board ("IRB") at the institution  performing
the clinical study.  An IRB may require changes in a protocol,  and there can be
no  assurance  that an IRB  will  permit  any  given  study to be  initiated  or
completed.   In  addition,   the  FDA  may  order  the  temporary  or  permanent
discontinuation  of clinical  trials at any time. In light of this process,  the
Company  must  necessarily  rely on other  persons and  institutions  to conduct
studies.

         All  the  results  of  the  preclinical  and  clinical   studies  on  a
pharmaceutical  product  are  submitted  to the  FDA in the  form  of an NDA for
approval to commence commercial  distribution.  The information contained in the
DMF is also incorporated into the NDA.  Submission of an NDA does not assure FDA
approval for marketing. The application review process takes more than two years
on average to complete.  However,  the process may take substantially  longer if
the FDA has  questions  or  concerns  about a product or studies  regarding  the
product.  In general,  the FDA  requires at least two  adequate  and  controlled
clinical studies  demonstrating  efficacy with sufficient  levels of statistical
assurance. However, additional support may be required. The FDA also may request
additional  information  relating  to  safety  or  efficacy,  such as  long-term
toxicity studies. In responding to an NDA, the FDA may grant marketing approval,
require  additional  testing  and/or  information,   or  deny  the  application.
Accordingly,  there  can be no  assurance  about  any  specific  time  frame for
approval,  if any,  of  products  by the  FDA or  foreign  regulatory  agencies.
Continued  compliance with all FDA  requirements  and conditions  relative to an
approved application,  including product  specification,  manufacturing process,
labeling  and   promotional   material,   and  record   keeping  and   reporting
requirements,  is necessary  throughout  the life of the  product.  In addition,
failure to comply with FDA requirements, the occurrence of unanticipated adverse
effects during  commercial  marketing or the result of future studies could lead
to the need for product recall or other  FDA-initiated  actions that could delay
further marketing until the products or processes are brought into compliance.

         The facilities of each  pharmaceutical  manufacturer must be registered
with and  approved by the FDA as  compliant  with United  States GMP.  Continued
registration  requires  compliance  with  standards  for United  States  GMP. In
complying  with United States GMP,  manufacturers  must continue to expend time,
money and effort in  production,  record  keeping and quality  control to ensure
technical  compliance.  In addition,  manufacturers  must comply with the United
States  Department  of Health and Human  Services  and  similar  state and local
regulatory  authorities if they handle controlled  substances,  and they must be
registered with the United States  Environmental  Protection  Agency and similar
state and local regulatory authorities if they generate toxic or dangerous waste
streams.  Other regulatory  agencies such as the Occupational  Safety and Health
Administration  also monitor a manufacturing  facility for  compliance.  Each of
these  organizations  conducts  periodic  establishment  inspections  to confirm
continued  compliance with its regulations.  Failure to comply with any of these
regulations  could mean fines,  interruption  of  production  and even  criminal
prosecution.

         For foreign markets, a pharmaceutical  company is subject to regulatory
requirements,  review procedures and product approvals which, generally,  may be
as extensive, if not more extensive, as those in the United States. Although the
technical  descriptions  of  the  clinical  trials  are  different,  the  trials
themselves  are  often  substantially  the same as those in the  United  States.
Approval of a product by regulatory  authorities  of foreign  countries  must be
obtained prior to commencing  commercial  product  marketing in those countries,
regardless of whether FDA approval has been obtained. The time and cost required
to obtain  market  approvals in foreign  countries may be longer or shorter than
required for FDA approval and may be subject to delay. There can be no assurance
that  regulatory  authorities  of foreign  countries  will grant  approval.  The
Company has no experience in manufacturing or marketing in foreign countries nor
in matters such as currency regulations,  import-export  controls or other trade
laws.

COMPETITION

         The  biopharmaceutical  industry is  characterized  by rapidly evolving
technology and intense  competition.  Research on AIDS and cancer,  the areas in
which the Company  has  particular  interests,  is being  conducted  by numerous
highly skilled scientists at prestigious universities, research institutions and
governmental  agencies  throughout the world.  Accordingly,  the  competition to
develop and  commercialize  medical  products and processes  must be regarded as
intense. Further,  competition in the medical field is likely to intensify. Many
of the Company's  competitors  have  substantially  greater  financial and other
resources,  large in-house  research,  development,  manufacturing and marketing
staffs and significantly greater experience with regulatory approval procedures.
The Company  does not have such  resources  and does not intend to compete  with
major pharmaceutical companies in drug manufacturing or marketing.

         Colleges,  universities,  governmental  agencies  and other  public and
private  research  organizations  continue to conduct  research and are becoming
more active in seeking patent  protection and licensing  arrangements to collect
royalties for use of technology that they have  developed,  some of which may be
directly competitive with that of the Company. The Company expects technological
development  to occur at a rapid rate and expects  competition  to  intensify as
advances occur in the development of pharmaceutical products of biologic origin.
However, the

                                      -13-
<PAGE>
Company intends to obtain, in consideration for research funding, sublicenses or
other rights to  technologies  from such entities and to pay royalties  upon any
successful commercial development of products derived therefrom. To such extent,
such  entities  may be  considered  to be  assisting  the  Company  rather  than
competing with it.

         Although the principal  investigators  under the Company's existing and
proposed  Sponsored  Research  Agreements  are not  aware of  other  researchers
conducting substantially similar research to that encompassed by their projects,
no  assurance  can be given in this regard.  The  scientific  community  and the
medical  field of research  regarding  AIDS and  prostate  cancer is  relatively
small,  and the number of approaches and  scientific  theories may be narrowing.
Accordingly,  there can be no  assurance  that others are not  contemporaneously
conducting the same or similar research to that of the Company and, accordingly,
that others might not complete and  commercialize  their  research  prior to the
time that the Company does so. The Company would likely be adversely impacted if
competitors  complete and  commercialize  their research prior to the Company if
such   resulting   therapeutic  or  diagnostic   pharmaceutical   is  effective,
notwithstanding  that the product  may not  infringe  upon any of the  Company's
proprietary rights.

ITEM 6.  MANAGEMENT'S DISCUSSION AND ANALYSIS OR PLAN OF OPERATION.

OVERVIEW

         The  Company  was  originally  formed  in 1986 as  Sheffield  Strategic
Metals,  Inc.,  a  Canadian  company,  to  engage  in  mineral  exploration  and
development.  It conducted no significant  business  activities  from 1986 until
late 1991.  Between  December  1991 and  February  1992 the Company  changed its
strategic   direction   to   focus   on   the   acquisition,   development   and
commercialization  of promising  biomedical  technologies  and raised capital in
private  placements of its common stock.  In April 1992, the Company changed its
name to  Sheffield  Medical  Technologies  Inc. to reflect the nature of its new
business and listed its common stock on the NASDAQ Small Cap Market. In November
1993, the Company commenced trading of its Common Stock on the AMEX.

         Since its inception in 1986,  the Company has been a development  stage
enterprise.  The  Company  has  incurred a net loss in each of the fiscal  years
since its inception and has had to rely on outside  sources of funds to maintain
its liquidity.  Substantial operating losses are expected to be incurred for the
next several years as the Company expends its resources for product acquisition,
sponsored  research and development and  preclinical and clinical  testing.  The
Company has  financed  its  technology  development  activities  and  operations
primarily  through  public and private  offerings of  securities.  The Company's
operating  results have fluctuated  significantly  during each quarter since its
change of strategic  direction in 1992,  and the Company  anticipates  that such
fluctuations, largely attributable to varying sponsored research and development
commitments and expenditures, will continue into the foreseeable future.

                                      -15-

<PAGE>
FISCAL YEARS ENDED DECEMBER 31, 1996 AND 1995

         In 1996,  the Company  signed its first  sub-license  agreement for its
Liposome-CD4  technology  and earned a  sub-license  fee,  which is  included in
sub-license  fee  revenue.  Interest  income was $163,664 in 1996 and $80,610 in
1995,  and a total of  $396,913  since  the  Company's  inception  in 1986.  The
increase in 1996 interest income of $83,054, compared to 1995, was due primarily
to the increase in the amount of funds available for investment as the result of
the  completion of the Company's  warrant  discount  program  completed in 1996,
which raised total gross proceeds of $5.6 million.

         Research  and  product  development  expenses  for  1996  decreased  by
$582,336 to  $3,841,818  compared with 1995  expenses of  $4,424,154.  The lower
research and development  costs were  attributable to negotiating  extensions of
two major Sponsored  Research  Agreements signed in October 1996 and the winding
down of the RBC-CD4 Electroinsertion Technology project, partially offset by the
increased  development of the Ion  Anti-Proliferative  technology  projects.  In
1996,  the  Company  entered  into  five  (5)  major  research  and  development
agreements.  See Note 6 to the  consolidated  financial  statements.  The  funds
expended for these new projects totaled $892,694 in 1996.

         General  and  administrative  expenses  for 1996  were  $3,831,204,  an
increase of $851,767  compared with expenses of $2,979,437  for 1995,  primarily
resulting  from the  one-time  cashless  exercise of options  and  warrants by a
former  employee  of the  Company,  totaling  $562,912,  and  private  placement
professional fees relating to Ion.

         Interest  expense for 1996 was $9,531,  a decrease of $55,205  compared
with interest expense for 1995 of $64,736.  The decrease was due to satisfaction
in full of the Company's $550,000 loan from SMT Investment  Partnership in 1995.
See Notes 4 and 7 to the consolidated financial statements.

         As a result of the above,  net loss for 1996  decreased  by $378,828 to
$7,008,889 compared with a net loss of $7,387,717 for 1995.

LIQUIDITY AND CAPITAL RESOURCES

         Since its inception,  the Company has financed its operations primarily
through  the sale of  securities,  from  which it has  raised  an  aggregate  of
approximately $24.7 million through December 31, 1996. On February 28, 1997, the
Company closed a private offering of 35,000 shares of its 7% Series A Cumulative
Convertible  Redeemable  Preferred  Stock,  which raised total gross proceeds of
$3.5 million. See Note 9 to the consolidated financial statements.  The proceeds
of  this  offering  will  be  used to  fund  research  and  development,  patent
prosecution and for working capital and general  corporate  purposes,  including
the possible acquisition of rights in new technologies in the Company's ordinary
course of business.

         From inception  through  December 31, 1996, the Company earned $396,913
in interest on cash, cash  equivalents and short-term  investments.  The Company
invests excess cash in cash  equivalents  and  short-term  investments in a cash
management  account that invests in U.S.  government  securities  and high grade
corporate  investments.  In  addition,  in 1996,  the  Company  signed its first
sub-license  agreement for its Liposome-CD4  technology and earned a sub-license
fee that is included in sub-license fee revenue.

         Net  cash  used  in  development   stage   activities  was  $6,043,876,
$7,541,937 and $23,521,045 during 1996, 1995, and from inception in 1986 through
1996, respectively. Cash of $6,420,834,  $9,346,901 and $25,220,193 was provided
by the issuance of securities in 1996,  1995 and from  inception in 1986 through
1996, respectively.

         The Company's  total assets at December 31, 1996, were  $2,773,884,  an
increase  of $552,834  from the  previous  year's  total  assets of  $2,221,050,
principally  due to an  increase  in cash and cash  equivalents  and  marketable
securities,  reflecting the cash received from the warrant  discount program and
sub-license revenue. The Company's  liabilities at December 31, 1996, consisting
of accounts payable,  sponsored research and capital lease obligations,  totaled
$1,078,047 compared to $428,687 at December 31, 1995.

         The Company spent approximately $15.5 million through December 31, 1996
to fund  certain  ongoing  technology  research  projects  and  expects to incur
additional  costs  in the  future,  including  costs  relating  to  its  ongoing
sponsored research and development activities,  preclinical and clinical testing
of its product  candidates and the hiring of additional  personnel.  The Company
may  also  bear  considerable  costs in  connection  with  filing,  prosecuting,
defending  and/or enforcing its patent and other  intellectual  property claims.
Therefore,  the Company will need substantial  additional capital before it will
recognize significant cash flow from operations, which is contingent on

                                      -16-
<PAGE>
the successful  commercialization of the Company's technologies by third parties
through  licenses,  joint  ventures  or  other  arrangements.  There  can  be no
assurance that any of the technologies to which the Company currently has or may
acquire rights to can or will be commercialized  or that any revenues  generated
from such  commercialization  will be  sufficient  to fund  existing  and future
research and development activities.

         While the Company  does not believe that  inflation  has had a material
impact on its results of operations, there can be no assurance that inflation in
the future will not impact  financial  markets  which,  in turn,  may  adversely
affect the Company's valuation of its securities and, consequently,  its ability
to raise additional capital,  either through equity or debt instruments,  or any
off-balance sheet refinancing arrangements,  such as collaboration and licensing
agreements with other companies.

         The Company expects that its existing capital resources,  including the
current  private  placement  offering  noted  above,  will enable it to fund its
operations for at least the next 12 months.  Because the Company does not expect
to generate  significant  cash flows from operations for at least several years,
the Company believes it will require additional funds to meet future costs.

         The  Company   will   attempt  to  meet  the  balance  of  its  capital
requirements  with  existing  cash  balances  and through  additional  public or
private  offerings of its securities,  debt  financing,  and  collaboration  and
licensing arrangements with other companies.  There can be no assurance that the
Company  will be able to  obtain  such  additional  funds  or  enter  into  such
collaborative and licensing  arrangements on terms favorable to the Company,  if
at all. The Company's sponsored research and technology  development program may
be curtailed if future financings are not completed.

ITEM 8.  CHANGES  IN  AND  DISAGREEMENTS  WITH  ACCOUNTANTS  ON  ACCOUNTING  AND
         FINANCIAL DISCLOSURE

         On January  10,  1995,  KPMG Peat  Marwick  LLP  ("KPMG")  resigned  as
independent  accountants  to the  Company.  KPMG's  accountant's  report  on the
financial  statements  of the  Company for the past two years did not contain an
adverse  opinion or a disclaimer of opinion and was not qualified or modified as
to uncertainty, audit scope, or accounting principles, except that KPMG's report
dated  February 11, 1994 on the  consolidated  balance  sheet as of December 31,
1993, and the consolidated  statements of operations,  stockholders'  equity and
cash flows for the years  ended  December  31, 1993 and 1992 and the period from
October 17, 1986 (inception) to December 31, 1993 contained a separate paragraph
stating that the  Company's  "recurring  losses and net deficit  position  raise
substantial doubt about its ability to continue as a going concern. Management's
plans in  regard  to  these  matters  are  described  in Note 8.  The  financial
statements do not include any adjustments  that might result from the outcome of
this  uncertainty."  There were no  disagreements  on any  matter of  accounting
principles or practices,  financial  statement  disclosure or auditing  scope or
procedure,  which  disagreements,  if not resolved to the  satisfaction of KPMG,
would  have  caused  it  to  make   reference  to  the  subject  matter  of  the
disagreements  in connection with its reports.  On March 2, 1995,  Ernst & Young
LLP was engaged as the new independent accountants to the Company.

         sale  price of Common  Stock of $3.75 per  share  reported  by AMEX for

ITEM 12.  CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

SMT LOAN

         On January 23, 1995, SMT made a loan (the "SMT Loan") to the Company in
the principal  amount of $550,000  pursuant to a demand loan agreement (the "SMT
Loan  Agreement").  Under the terms of the SMT Loan Agreement,  SMT could demand
the  payment  in full of the SMT  Loan at any  time.  To  secure  the  Company's
obligations  under the SMT Loan  Agreement,  the Company  granted SMT a security
interest in substantially all of the Company's  assets,  which security interest
has since been  released.  The note  evidencing  the SMT Loan (the "Original SMT
Note") was exchanged  pursuant to the terms of the SMT Loan  Agreement for a new
note (the "SMT Convertible  Note") that permitted the holder to exchange the SMT
Convertible  Note (in  whole,  but not in part)  into  200,000  shares of Common
Stock. In addition, the SMT Loan Agreement required the Company upon issuance of
the SMT  Convertible  Note to issue to SMT  warrants  (the  "SMT  Warrants")  to
acquire  200,000  shares of Common Stock at any time within five years after the
date of issue for a price of $4.00 per share. The SMT Warrants are redeemable by
the Company for $4.00 per share at any time after the price of the Common  Stock
exceeds an  average of $6.00 per share for 20  business  days.  SMT was  granted
certain  registration  rights with respect to the Common  Stock  issuable to SMT
upon  conversion of the SMT  Convertible  Note and the SMT  Warrants.  By letter
dated June 1, 1995, SMT exercised its right to convert the SMT Convertible  Note
into 200,000 shares of Common Stock and subsequently  assigned the right to such
shares to an unaffiliated third party.

         As a  condition  to making  the SMT Loan,  the Board of  Directors  was
expanded by the election of John R. Lakian, George R. Begley, Andrew Monness and
Dr. Stephen Sohn, all nominees of SMT.  Messrs.  Lakian and Monness  resigned as
directors  of the  Company  as of May 24,  1995  and Mr.  Begley  resigned  as a
director as of July 6, 1995.

         All the time of the making of the SMT Loan,  Messrs.  Begley and Lakian
and Dr. Stephen Sohn were general partners of SMT. In addition,  Messrs.  Begley
and Lakian and Dr. Stephen Sohn were executive  officers of The Fort Hill Group,
Inc. ("Fort Hill"), a former financial adviser to the Company, at such time.

         Fort Hill served as financial advisor to the Company in connection with
the  Company's  private  placement  of units (each  consisting  of two shares of
Common Stock and one warrant to purchase an  additional  share of Common  Stock)
that was  consummated  in April 1995 (the "First 1995 Unit Private  Placement").
For its  financial  advisory  services,  Fort Hill was paid $177,470 in fees and
commissions.  In addition,  the Company  issued Fort Hill a five year warrant to
purchase  30,000  shares of Common  Stock  with an  exercise  price of $3.25 per
share.

         Global Equities, an investment firm headquartered in Paris, France, was
paid commissions  totalling $45,440 for services provided in connection with the
First 1995 Unit  Private  Placement.  In  addition,  the Company  issued  Global
Equities  units  consisting  of 25,000  shares of Common  Stock and  warrants to
purchase 12,500  additional shares of Common Stock at an exercise price of $5.00
per share.  Bernard  Laurent,  a Director of the Company,  and Patrick  Piard, a
former Director of the Company, are also principals of Global Equities.

CONSULTING ARRANGEMENTS

         Dr.  Stephen  Sohn and  Bernard  Laurent  received  fees of $16,667 and
$72,000,  respectively,  in 1996 from the Company in consideration of scientific
and financial consulting services rendered to the Company by them.

OTHER TRANSACTIONS

         In connection with Arthur M. Jenke's  resignation as Director and Chief
Financial  Officer of the Company in September  1994, the Company entered into a
consulting agreement with Mr. Jenke. Pursuant to the consulting  agreement,  Mr.
Jenke agreed to provide advice to the Company in connection with various Company
matters,  including  periodic  filings  and  registration  statements  with  the
Commission.  Mr. Jenke received  approximately $5,300 per month for his services
under the consulting agreement,  and was reimbursed for his related expenses. In
addition,  the consulting  agreement  provides that the Company shall permit Mr.
Jenke to effect a  "cashless"  exercise  of all of his  outstanding  options and
warrants.  Mr.  Jenke's  services to the Company as a  consultant  concluded  in
January 1995.  The Company  issued Mr. Jenke  162,877  shares of Common Stock in
September,  1996 in satisfaction of its obligation to effect a cashless exercise
of Mr. Jenke's outstanding options and warrants.

                         Report of Independent Auditors


To Board of Directors and Stockholders
Sheffield Medical Technologies Inc.


We have audited the accompanying consolidated balance sheet of Sheffield Medical
Technologies  Inc. and  subsidiaries  (a  development  stage  enterprise)  as of
December  31,  1996,  and the related  consolidated  statements  of  operations,
stockholders'  equity,  and cash flows for the years ended December 31, 1996 and
1995, and for the period October 17, 1986 (inception) through December 31, 1996.
These financial  statements are the responsibility of the Company's  management.
Our responsibility is to express an opinion on these financial  statements based
on our audits.  The consolidated  financial  statements as of December 31, 1993,
and for the period October 17, 1986 (inception)  through December 31, 1993, were
audited by other  auditors  whose  report dated  February 11, 1994  expressed an
unqualified  opinion on those  statements and included an explanatory  paragraph
that stated that the Company's  "recurring losses and net deficit position raise
substantial  doubt about its ability to  continue as a going  concern.  The 1993
financial  statements do not include any adjustments  that might result from the
outcome of this  uncertainty."  The  consolidated  financial  statements for the
period October 17, 1986 (inception) through December 31, 1993 include cumulative
net  losses  of  $5,872,416.  Our  opinion  on the  consolidated  statements  of
operations,  stockholders' equity and cash flows for the period October 17, 1986
(inception)  through  December  31,  1996,  insofar as it relates to amounts for
prior periods through  December 31, 1993, is based solely on the report of other
auditors.

We  conducted  our  audits  in  accordance  with  generally   accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the  accounting  principles  used and  significant  estimates  made by
management,  as well as evaluating the overall financial statement presentation.
We believe that our audits and the report of other auditors provide a reasonable
basis for our opinion.

In our  opinion,  based on our  audits,  and for the  period  October  17,  1986
(inception)  through  December  31,  1993,  the  report of other  auditors,  the
financial statements referred to above present fairly, in all material respects,
the consolidated  financial position of Sheffield Medical  Technologies Inc. and
subsidiaries  at  December  31,  1996,  and the  consolidated  results  of their
operations  and their cash flows for the years ended  December 31, 1996 and 1995
and the period from October 17, 1986  (inception)  through December 31, 1996, in
conformity with generally accepted accounting principles.

The accompanying  consolidated  financial statements have been prepared assuming
that Sheffield  Medical  Technologies  Inc. and subsidiaries  will continue as a
going concern. As more fully described in Note 1, the Company has generated only
minimal operating revenue,  has incurred recurring operating losses and requires
additional capital. These conditions raise substantial doubt about the Company's
ability to continue as a going concern. The consolidated financial statements do
not  include  any  adjustments  that  might  result  from  the  outcome  of this
uncertainty.

                          INDEPENDENT AUDITORS' REPORT



The Board of Directors and Stockholders
Sheffield Medical Technologies Inc.:


We  have  audited  the  accompanying   consolidated  statements  of  operations,
stockholders'  equity  (net  capital  deficiency)  and cash  flows of  Sheffield
Medical  Technologies  Inc. and subsidiary (a development  stage enterprise) for
the period from October 17, 1986  (inception) to December 31, 1993 (not included
separately  herein).  The financial  statements  are the  responsibility  of the
Company's  management.  Our  responsibility  is to  express  an opinion on these
financial statements based on our audits.

We  conducted  our  audits  in  accordance  with  generally   accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit also includes  assessing the accounting  principles used
and significant estimates made by management,  as well as evaluating the overall
financial  statement  presentation.   We  believe  that  our  audits  provide  a
reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above presents
fairly, in all material respects,  the results of Sheffield Medical Technologies
Inc. and subsidiary's  operations and cash flows for the period from October 17,
1986  (inception)  to December 31, 1993 in conformity  with  generally  accepted
accounting principles.

The accompanying  consolidated  financial statements have been prepared assuming
that  the  Company  will  continue  as a  going  concern.  As  reflected  in the
accompanying  consolidated financial statements,  the Company's recurring losses
raise  substantial  doubt  about its  ability to  continue  as a going  concern.
Management's  plans in regard to these  matters were  described in note 8 to the
December 31, 1993 financial  statements (not included  separately  herein).  The
consolidated  financial  statements  do not include any  adjustments  that might
result from the outcome of this uncertainty.

                        (A DEVELOPMENT STAGE ENTERPRISE)
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

 1.   DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION

      Sheffield  Medical  Technologies  Inc.  ("Sheffield")  was incorporated on
      October  17,  1986,  under  the  Canada  Business  Corporations  Act.  The
      Company's wholly-owned  subsidiary,  U-Tech Medical Corporation ("U-Tech")
      was incorporated in the state of Texas on January 13, 1992 and is inactive
      at December 31, 1996. On January 10, 1996,  Ion  Pharmaceuticals,  Inc., a
      Delaware corporation  ("Ion"), was formed as a wholly-owned  subsidiary of
      the Company.  At that time, Ion acquired the Company's rights with respect
      to  the  anti-proliferative   technology.   Unless  the  context  requires
      otherwise, Sheffield, U-Tech and Ion are referred to as "the Company". The
      Company  commenced  its  biotechnology  operations in the United States in
      January 1992 under new management and Sheffield  became  domesticated as a
      Wyoming  corporation in May 1992. At the Annual Meeting of shareholders of
      the Company held on January 26, 1995, the Company's  shareholders approved
      the proposal to reincorporate the Company in Delaware,  which was effected
      on June 13, 1995. All significant intercompany transactions are eliminated
      in consolidation.

      The Company is in the development  stage and to date has been  principally
      engaged in research  and  licensing  efforts.  The  Company has  generated
      minimal  operating  revenue  and  requires  additional  capital  which the
      Company intends to obtain through equity and debt offerings to continue to
      operate its business.  The Company's  ability to meet its  obligations  as
      they become due and to continue as a going  concern must be  considered in
      light of the expenses,  difficulties and delays frequently  encountered in
      starting a new  business,  particularly  since the  Company  will focus on
      research,  development and unproven technology which may require a lengthy
      period  of time and  substantial  expenditures  to  complete.  Even if the
      Company is able to  successfully  develop new  products  or  technologies,
      there  can be no  assurance  that the  Company  will  generate  sufficient
      revenues from the sale or licensing of such products and  technologies  to
      be profitable.  Management believes that the Company's ability to meet its
      obligations as they become due and to continue as a going concern  through
      December 1997 are dependent upon obtaining additional financing.

      The accompanying consolidated financial statements have been prepared on a
      going  concern  basis which  contemplates  the  realization  of assets and
      satisfaction  of  liabilities  and  commitments  in the  normal  course of
      business. The Company has incurred net losses of $7,008,889 and $7,387,717
      during the years ended December 31, 1996, and 1995  respectively,  and has
      an accumulated  deficit of $26,588,652  from inception  (October 17, 1986)
      through December 31,1996.


2.    SIGNIFICANT ACCOUNTING POLICIES

      CASH EQUIVALENTS

      The  Company  considers  all  highly  liquid   instruments  with  original
      maturities of three months or less to be cash equivalents.

      MARKETABLE SECURITIES

      Marketable  securities  generally  consist  of  investments  which  can be
      readily  purchased  or  sold  using  established  markets.  The  Company's
      securities,  which are  classified as  available-for-sale,  are carried at
      market with unrealized  gains and losses reported as a separate  component
      of stockholders equity.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

      PROPERTY AND EQUIPMENT

      Property and  equipment is stated at cost.  Depreciation  is computed over
      three or five year periods using the straight-line method.

      Assets under capital leases,  consisting primarily of office equipment and
      improvements,  are  amortized  over the lesser of the  useful  life or the
      applicable  lease terms,  whichever is shorter,  which  approximate  three
      years.

      RESEARCH AND DEVELOPMENT COSTS

      Company-sponsored  research  and  development  costs ("R & D  costs")  are
      expensed as incurred,  except for fixed  assets,  to which the Company has
      title,  which are capitalized and depreciated  over their estimated useful
      lives. LOSS PER SHARE OF COMMON STOCK

      The computation of loss per common share is based on the  weighted-average
      number of outstanding  common  shares.  Common stock  equivalents  are not
      included because the effect would be antidilutive. USE OF ESTIMATES

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

      STOCK BASED COMPENSATION

      As  permitted  by FASB  Statement  No. 123,  "Accounting  for  Stock-Based
      Compensation"  (FASB 123),  the  Company has elected to follow  Accounting
      Principal Board Opinion No. 25,  "Accounting  for Stock Issued  Employees"
      (APB 25) and related  interpretations  in accounting  for its stock option
      plans.  Under APB 25, no expense is recognized at the time of option grant
      because the exercise  price of the Company's  employee stock option equals
      the fair market value of the underlying common stock on the date of grant.

3.    LEASES

      Included  in  property  and  equipment  are  capital  leases as follows at
      December 31, 1996:

      Office equipment                            $ 51,978

            There were no assets under capital leases at December 31, 1995.

      The company has sub-leases for office space in four locations which expire
      at various times between  April,  1997 and December 31, 1998.  The Company
      also leases certain office equipment under a capital lease that expires in

      officer of Sheffield, in September 1994.

      In March 1994, a total of  $3,121,164  was  received  from the exercise of

      and a warrant to purchase one share of common stock at a price of $5.00 at
      any time up until and  including  February  10,  2000.  The  warrants  are
      redeemable by the Company under certain circumstances.

      On January 23,  1995,  SMT made a 10% loan (the "SMT Loan") to the Company
      in the principal  amount of $550,000  pursuant to a demand loan  agreement
      (the SMT Loan Agreement").  Under the terms of the SMT Loan Agreement, SMT
      could  demand the  payment in full of the SMT Loan at any time or December
      31, 1996 whichever came first. To secure the Company's  obligations  under
      the SMT Loan  Agreement,  the Company  granted SMT a security  interest in
      substantially  all of the Company's  assets,  which security  interest has
      since been released.  The note  evidencing the SMT Loan (the "Original SMT
      Note") was exchanged pursuant to the terms of the SMT Loan Agreement for a
      new note  (the  "SMT  Convertible  Note")  that  permitted  the  holder to
      exchange  the SMT  Convertible  Note (in  whole or in part)  into  200,000
      shares of Common Stock. In addition,  the SMT Loan Agreement  required the
      Company upon issuance of the SMT Convertible Note to issue to SMT warrants
      (the "SMT Warrants") to acquire 200,000 shares of Common Stock at any time
      within  five years after the date of issue for a price of $4.00 per share.
      The SMT Warrants are  redeemable by the Company for $4.00 per share at any
      time after the price of the Common  Stock  exceeds an average of $6.00 per
      share for 20 business days. SMT was granted  certain  registration  rights
      with respect to the Common Stock  issuable to SMT upon  conversion  of the
      SMT convertible  Note and SMT Warrants.  By letter dated June 1, 1995, SMT
      exercised  its right to  convert  the SMT  Convertible  Note into  200,000
      shares of Common Stock and subsequently  assigned the right to such shares
      to an unaffiliated third party.

      In July 1995, the Company completed a private placement of 1,375,000 units
      to accredited investors at a price of $4.00 per unit for gross proceeds of
      $5,500,000.  Each such unit consists of one share of the Company's  Common
      Stock and a warrant to  purchase  one share of common  stock at a price of
      $4.50 at any time up until and including  February 10, 2000.  The warrants
      are redeemable by the Company under certain circumstances.

      On April 30, 1996,  the Company  completed  its warrant  discount  program
      through which the Company  offered  holders of warrants  issued in private
      placements  completed in 1995 the opportunity to exercise such warrants at
      up to a 121/2 % discount from the actual exercise prices of such warrants.
      A total of $5.6  million was received  from the exercise of such  warrants
      with the related issuance of 1,373,250 shares of common stock.

5.    STOCK OPTIONS AND WARRANTS

      The 1993 Stock Option Plan was adopted by the Board of Directors in August
      1992 and approved by the  shareholders  at the annual  meeting in December
      1993. An amendment to the Plan received  shareholder approval on March 15,
      1995. Under the Stock Option Plan, the maximum  aggregate number of shares
      which may be optioned and sold is 1,000,000  shares of common  stock.  The
      Stock  Option Plan  permits  the grant to  employees  and  officers of the
      Company of both incentive stock options and  non-statutory  stock options.
      The Stock  Option  Plan is  administered  by the Board of  Directors  or a
      committee of the Board,  which determines the persons to whom options will
      be granted and the terms thereof, including the exercise price, the number
      of shares subject to each option,  and the  exercisability of each option.
      The exercise price of all options for common stock granted under the Stock

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

      Plan must be at least equal to the fair market  value on the date of grant
      in the case of incentive stock options and 85% of the fair market value on
      the date of grant in the case of  incentive  stock  options and 85% of the
      fair market value on the date of grant in the case of non-statutory  stock
      options.  Options  generally  expire five years from the date of grant and
      vest upon  continuous  employment  by the Company for 12 months  after the
      date of grant.

      The 1993  Restricted  Stock Plan under  which  shares of the  Company  are
      reserved,  in such amounts as determined  by the Board of  Directors,  for
      issuance as part of the total shares  reserved under the Stock Option Plan
      described  above, was adopted by the Board of Directors in August 1992 and
      approved  by  the  shareholders  at the  annual  shareholders  meeting  in
      December 1993. The Restricted Stock Plan authorized the grant of a maximum
      of  150,000  shares  of  common  stock  to  key  employees,   consultants,
      researchers and members of the Company's  Scientific  Advisory Board.  The
      Restricted  Stock  Plan is  administered  by the Board of  Directors  or a
      committee of the Board, which determines the person to whom shares will be
      granted  and the terms of such share  grants.  As of the date  hereof,  no
      shares have been granted under the 1993 Restricted Stock Plan.

      The 1996 Directors Stock Option Plan was adopted by the Board of Directors
      and approved by the  shareholders on June 20, 1996. Under the Stock Option
      Plan,  the maximum  aggregate  number of shares  which may be optioned and
      sold is 500,000  shares of common stock.  The Directors  Stock Option Plan
      granted each eligible  director  15,000 stock options.  To the extent that
      shares remain  available,  any new directors shall receive the grant of an
      Option to  purchase  25,000  shares.  To the  extent  that  Shares  remain
      available under the plan, on January 1 of each year commencing  January 1,
      1997, each eligible director shall be granted an option to purchase 15,000
      shares.  The exercise  price of all options  granted  under the  Directors
      Stock Option Plan shall be the fair market value at the date of the grant.
      Options  generally  expire  five years  from the date of grant.  As of the
      December  31,  1996,  45,000  shares  have  been  granted  under  the 1996
      Directors Stock Option Plan.

      At the annual meeting of  stockholders  of the Company held on January 26,
      1995,  the  company's  shareholders  approved an increase in the number of
      shares of common stock  available  for issuance  pursuant to the Company's
      1993 Stock Option Plan from 250,000 shares to 500,000 shares.

      On January  23,  1995,  the Company  granted  stock  purchase  warrants to
      purchase  200,000  shares of the  Company's  common  stock  issuable  upon
      conversion of an exchangeable  demand note to a financial advisor. In June
      1995,  such  warrants were  exercised for 200,000  shares of the Company's
      Common Stock.

      On February 13, 1995, the Company  granted  options to purchase a total of
      200,000  shares of the  Company's  common stock to four new members of the
      Board of Directors at an exercise price of $4.00 which  approximated  fair
      market value.

      At the annual  meeting of  stockholders  of the  Company  held on June 20,
      1996,  the  Company's  shareholders  approved an increase in the number of
      shares available for issuance  pursuant to the Company's 1993 Stock Option
      Plan from 500,000 shares to 1,000,000 shares.

      FASB 123 requires pro forma information  regarding net income and earnings
      per  share as if the  Company  has  accounted  for its stock  options  and
      warrants  granted  subsequent  to December 31, 1994,  under the fair value
      method of FASB 123. The fair value of these stock  options and warrants is
      estimated at the date of grant using a Black-Scholes  option pricing model
      with the  following  weighted  average  assumptions  for  1996  and  1995:
      risk-free interest of 6.23%,  6.13%, 6.00% and 5.57%;  expected volatility
      of 0.60;  expected  option  life of one to four years from  vesting and an
      expected dividend yield of 0.0%.

      For purposes of pro forma  disclosures,  the  estimated  fair value of the
      stock  options and  warrants is  amortized  to expense  over the  options'
      vesting period. The Company's pro forma information is as follows:

                                                            1996        1995

      Because FASB 123 is applicable only to equity awards granted subsequent to
      December 31, 1994, its pro forma effect will not be fully  reflected until
      1998.

      the Research  Technology derived from the agreement.  Under this amendment
      and its previous  agreement,  the Company has funded $180,153 for the year
      ended December 31, 1996.

      In 1996,  the Company  entered  into  quarterly  Research  and  Consulting
      Agreements  with  Pharm-Eco  Laboratories,  Inc. for the  development  and
      synthesis  of  novel   compounds   related  to  the  Ion   Pharmaceuticals
      Technologies.  The  agreements  require the Company to pay  $175,000  plus
      expenses  each quarter for related  research and  consulting.  Under these
      agreements the Company has funded $773,522 for the year ended December 31,
      1996.

7.    RELATED PARTY TRANSACTIONS

      On January 23, 1995, SMT made a $550,000 loan to the Company pursuant to a
      demand loan  agreement.  In June 1995,  SMT exercised its right to convert
      the  SMT   convertible   note  to  200,000  shares  of  common  stock  and
      subsequently  assigned the right to such shares to an  unaffiliated  third
      party in exchange for repayment of the loan and interest. In addition, the
      Company,  as required under the Note,  issued  warrants to acquire 200,000
      shares of common  stock at any time  within  five years  after the date of
      issuance  at a price  equal to $4.00 per share (See Note 4).  Dr.  Stephen
      Sohn, a member of the Board of  Directors of the Company,  is also general
      partner of SMT.

8.    INCOME TAXES

      The Company  utilizes the  liability  method to account for income  taxes.
      Under this method,  deferred  tax assets and  liabilities  are  determined
      based on differences  between financial  reporting and tax bases of assets
      and  liabilities  and are measured  using  enacted tax rates and laws that
      will be in effect when the differences are expected to reverse.

      Deferred  income taxes  reflect the net effects of  temporary  differences
      between  the  carrying  amounts of assets and  liabilities  for  financial
      reporting   purposes  and  the  amounts  used  for  income  tax  purposes.
      Significant components of the Company's net deferred tax asset at December
      31, 1996 which is considered noncurrent, are as follows:

         Deferred tax assets:
              Net operating loss carryforwards                    $  8,800,000
              Capitalized start-up costs for tax purposes              578,000
              Deferred tax asset valuation allowance                (9,378,000)
                                                                  -------------
                  Net deferred tax asset                          $       -

      The  valuation  allowance for deferred tax assets as of December 31, 1995,
      was $6,678,000.  The net change in the total  valuation  allowance for the
      year ended December 31, 1996,  was an increase of $2,700,000.  At December
      31,  1996,   the  Company  has  net  operating   loss   carryforwards   of
      approximately  $24,400,000  for tax purposes which are available to offset
      federal taxable income, if any, through 2011. An ownership change pursuant
      to Section 382 of the

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

      Internal  Revenue  Code  occurred  in April  1995 as a result of a private
      placement  of  the  Company's  common  stock  and  warrants.  Accordingly,
      utilization of the Company's  pre-change  net operating loss  carryforward
      (approximately  $13,600,000) is restricted to approximately $2,220,000 per
      year, and the related deferred tax assets have been fully reserved.

9.    SUBSEQUENT EVENTS

      On February  28,  1997,  the Company  closed a private  offering of 35,000
      shares of 7% Series A Cumulative Convertible Redeemable Preferred Stock at
      a purchase  price of $100.00 per Share,  which raised total gross proceeds
      of $3.5  million.  Each  investor is also  entitled  to receive  five-year
      Warrants to purchase  Common Stock of the Company  equal to 1/3 the number
      of shares of Common Stock issuable upon conversion of the Preferred Stock.
      The Warrants  will be issued at 110% of the closing bid price per share of
      the common stock on the closing  date.  Proceeds  will be used for funding
      research and development,  patent prosecution, and for working capital and
      general corporate purposes,  including the possible  acquisition of rights
      in new technologies in the Company's ordinary course of business.

      On March 14, 1997, the Company  signed a letter of intent to acquire,  for
      stock, Camelot Pharmacal, L.L.C., a privately held emerging pharmaceutical
      company.  As part of the contemplated  transaction,  Camelot's  management
      team would join the  Company.  Camelot's  product  portfolio  consists  of
      late-stage  development  opportunities.  The acquisition is expected to be
      completed by the end of May,  1997.  As part of the business  combination,
      Camelot's principals will have the opportunity to invest in the Company by
      purchasing up to $5.0 million of common stock at current market prices.

                     shall be set forth in this Certificate of Incorporation.

                     3.  Whenever the  Corporation  shall be authorized to issue

                     entitle  the holder  thereof to notice of, and the right to
                     vote  at,  any  meeting  of   stockholders.   Whenever  the
                     Corporation  shall be  authorized  to issue  more  than one
                     class of stock, no outstanding  share of any class of stock
                     which is denied  voting power under the  provisions  of the
                     Certificate  of  Incorporation  shall  entitle  the  holder
                     thereof to the right to vote at any meeting of stockholders
                     except as the provisions of paragraph (2) of subsection (b)
                     of ss.242 of the  General  Corporation  Law of the State of
                     Delaware shall otherwise require;  provided,  that no share
                     of any such class which is  otherwise  denied  voting power
                     shall entitle the holder  thereof to vote upon the increase
                     or  decrease  in the  number of  authorized  shares of said
                     class.

         NINTH:  The personal  liability of the directors of the  Corporation is
hereby eliminated to the fullest extent permitted by paragraph (7) of subsection
(b) of ss.102 of the General  Corporation Law of the State of Delaware,  as same
may be amended and supplemented.

         TENTH: The Corporation shall, to the fullest extent permitted by ss.145

amended and supplemented, indemnify any and all persons whom it shall have power
to indemnify  under said  section from and against any and all of the  expenses,
liabilities or other matters referred to in or covered by said section,  and the
indemnification  provided for herein shall not be deemed  exclusive of any other
rights to which those  indemnified may be entitled under any By-Law,  agreement,
vote of stockholders or disinterested directors or otherwise,  both as to action
in his official capacity and as to action in another capacity while holding such
office,  and shall  continue  as to a person  who has  ceased to be a  director,
officer,  employee  or agent  and  shall  inure  to the  benefit  of the  heirs,
executors and administrators of such a person.

         ELEVENTH:  From time to time any of the provisions of this  Certificate
of  Incorporation  may be amended,  altered or  repealed,  and other  provisions
authorized  by the laws of the  State of  Delaware  at the time in force  may be
added or inserted in the

amended to increase the authorized  shares of common stock of the Corporation by

FOURTH the following new Article FOURTH:

                  "FOURTH:  The  total  number  of  shares  of  stock  that  the
                  Corporation  shall have the  authority  to issue is (i) thirty
                  million  (30,000,000)  shares of Common Stock,  $.01 par value
                  ("Common Stock"), and (ii) three million (3,000,000) shares of
                  Preferred Stock, $.01 par value ("Preferred Stock").

         COMMON STOCK.

                  GENERAL.  The voting,  dividend and liquidation  rights of the
holders  of Common  Stock are  subject  to and  qualified  by the  rights of the
holders of the  Preferred  Stock of any series as may be designated by the Board
of Directors upon any issuance of the Preferred Stock of any series.

                  VOTING.  The holders of Common  Stock are entitled to one vote
for each share held at all meetings of stockholders (and written actions in lieu
of meetings). There shall be no cumulative voting.

                  DIVIDENDS.  Dividends  may be declared  and paid on the Common

time to  time to  issue  the  Preferred  Stock  in one or  more  series,  and in
connection  with the creation of any such series,  by resolution or  resolutions

preferences,  as shall be stated and expressed in such  resolutions,  all to the
full  extent  now or  hereafter  permitted  by the  General  Corporation  Law of
Delaware.  Without  limiting the  generality of the foregoing,  the  resolutions
providing  for issuance of any series of  Preferred  Stock may provide that such
series shall be superior or rank equally or junior to the Preferred Stock of any
other  series to the  extent  permitted  by law.  Except as  expressly  provided
elsewhere in this Article  FOURTH no vote of the holders of the Preferred  Stock
or Common  Stock shall be required in  connection  with the  designation  or the
issuance of any shares of any series of any  Preferred  Stock  authorized by and
complying  with the  conditions  herein,  the  right  to have  such  vote  being
expressly  waived by all present and future  holders of the capital stock of the
Corporation."

                                       OF
                   SERIES A CUMULATIVE CONVERTIBLE REDEEMABLE
                                 PREFERRED STOCK
                                       OF
                       SHEFFIELD MEDICAL TECHNOLOGIES INC.

                         (Pursuant to Section 151 of the
                General Corporation Law of the State of Delaware)

                              ---------------------

         Sheffield  Medical  Technologies  Inc.,  a  corporation  organized  and
existing  under  the  General  Corporation  Law of the  State of  Delaware  (the
"Corporation"),  hereby  certifies that the following  resolution was adopted by
the Board of Directors of the Corporation:

         RESOLVED,  that  pursuant  to the  authority  expressly  granted to and
vested in the Board of Directors of the  Corporation  (the "Board of Directors")
by the provisions of the Certificate of  Incorporation  of the Corporation  (the
"Certificate of Incorporation"),  there hereby is created,  out of the 3,000,000
shares of preferred stock of the Corporation authorized in Article FOURTH of the
Certificate of  Incorporation  (the  "Preferred  Stock"),  a series of Preferred
Stock consisting of 40,800 shares, which series shall have the following powers,
designations, preferences and relative, participating, optional or other rights,
and the following  qualifications,  limitations and restrictions (in addition to
the powers, designations,  preferences and relative, participating,  optional or
other rights, and the qualifications, limitations and restrictions, set forth in
the Certificate of Incorporation which are applicable to the Preferred Stock).

         Section 1.  DESIGNATION AND AMOUNT.  The shares of such series shall be
designated as "Series A Cumulative  Convertible Redeemable Preferred Stock" (the
"Series A Preferred  Stock") and the  authorized  number of shares  constituting
such series shall be 40,800. The par value of the Series A Preferred Stock shall
be $.01 per share.

         Section 2. DIVIDENDS.

         Subject  to  Section  4(d),  the  holders  of  shares  of the  Series A
Preferred  Stock will be entitled to  receive,  when,  as and if declared by the
Board of  Directors,  cumulative  stock  dividends on the shares of the Series A
Preferred Stock,  payable in shares of the Corporation's  common stock, $.01 par
value per share ("Common Stock"), at the rate per share of 7.0% per annum

<PAGE>
of the  original  $100.00  purchase  price per share of the  Series A  Preferred
Stock,  and no more.  Such stock  dividends shall be cumulative from the date of
the initial  issuance of shares of Series A Preferred Stock (the "Closing Date")
or the most recent date on which the full amount of accrued stock dividends have
been  paid,  as the  case  may  be,  on the  Series  A  Preferred  Stock  by the
Corporation.  Subject to, and as provided in, Section 4, the  Corporation  shall
pay all  cumulative  stock  dividends on the shares of Series A Preferred  Stock
held by a holder on the  Conversion  Date (as defined  below) in respect of such
holder's  election to convert Series A Preferred  Stock. The number of shares of
Common Stock to be issued as cumulative  stock  dividends on any such Conversion
Date shall  equal the cash  value of such  cumulative  dividends  divided by the
current  market  price per share of Common  Stock  (determined  as  provided  in
Section 5) as of such Conversion Date. The cash value of stock dividends payable
on shares of Series A Preferred  Stock for any full annual dividend period shall
be computed by  multiplying  the original  $100.00  purchase  price per share by
7.0%.  The cash value of  dividends  payable on shares of the Series A Preferred
Stock for any period less than a full annual  dividend  period shall be computed
on the basis of a 360-day year of twelve  30-day months and the actual number of
days elapsed in the period for which payable.

         If stock  dividends are not paid in full, or declared in full, upon the
shares of the Series A Preferred  Stock and shares of any other  preferred stock
ranking on a parity as to payment of stock dividends with the Series A Preferred
Stock,  all dividends  declared upon shares of the Series A Preferred  Stock and
any other  preferred  stock ranking on a parity as to payment of dividends  with
the Series A Preferred  Stock shall be paid or declared  PRO RATA so that in all
cases the  amount  of  dividends  paid or  declared  per  share on the  Series A
Preferred  Stock and such other shares of preferred stock ranking on a parity as
to payment of  dividends  with the Series A  Preferred  Stock shall bear to each
other the same ratio  that  accumulated  stock  dividends  per share,  including
dividends accrued or in arrears, if any, on the shares of the Series A Preferred
Stock and such other  shares of  preferred  stock bear to each other.  Except as
provided in the preceding  sentence,  unless full cumulative  stock dividends on
the shares of the Series A  Preferred  Stock have been paid or declared in full,
no dividends  (other than  dividends in shares of Common Stock,  or in shares of
any other  capital  stock of the  Corporation  ranking  junior  to the  Series A
Preferred  Stock as to payment of  dividends  and  distribution  of assets  upon
liquidation)  shall be paid or  declared  and set  aside  for  payment  or other
distribution  upon the Common Stock or, except as provided  above,  on any other
capital  stock of the  Corporation  ranking  junior  to or on a parity  with the
Series A Preferred  Stock as to dividends,  nor shall any shares of Common Stock
or shares of any other capital stock of the Corporation  ranking junior to or on
a parity  with the  Series  A  Preferred  Stock  as to  dividends  be  redeemed,
purchased or otherwise acquired for any consideration (or any payment made to or
available for a sinking fund for the redemption of any such

                                       -2-

<PAGE>
shares) by the  Corporation  or any  subsidiary  of the  Corporation  (except by
conversion  into or  exchange  for  shares of capital  stock of the  Corporation
ranking junior to the Series A Preferred Stock as to dividends and  distribution
of assets upon  liquidation).  Holders of shares of the Series A Preferred Stock
shall not be entitled to any dividends,  whether payable in capital stock,  cash
or property,  in excess of full accrued and cumulative stock dividends as herein
provided.  No interest  or sum of money in lieu of interest  shall be payable in
respect of any stock dividend  payment or payments on the shares of the Series A
Preferred  Stock  that may be in  arrears;  provided,  however,  that if,  on an
applicable Conversion Date (as defined herein),  stock dividends that would have
been  payable  on such  date  are not  paid  solely  due to the  failure  of the
Corporation's  Board of Directors to declare  such  dividends,  then the rate of
conversion  of the Series A Preferred  Stock to be converted on such  Conversion
Date shall be  adjusted  so that the  holders  would  receive the same amount of
shares of Common  Stock on such  Conversation  Date as such  holder  would  have
received if the Corporation's  Board of Directors had timely declared such stock
dividends.

         The terms "accrued  dividends,"  "dividends  accrued" and "dividends in
arrears," whenever used herein with reference to shares of preferred stock shall
be deemed to mean an amount  which  shall be equal to  dividends  thereon at the
applicable  annual  dividend rates per share for the  respective  series thereof
from the  date or  dates on which  such  dividends  commence  to  accrue  to the
applicable  payment date less the amount of all  dividends  paid, or declared in
full and sums set aside for the payment  thereof,  upon such shares of preferred
stock.

         Section 3. LIQUIDATION RIGHTS.

         (a) In the event of any  liquidation,  dissolution or winding up of the
affairs of the  Corporation,  whether  voluntary or otherwise,  after payment or
provision for payment of the debts and other liabilities of the Corporation, the
holders of shares of the Series A Preferred  Stock shall be entitled to receive,
in cash,  out of the  remaining  net  assets of the  Corporation  (whether  from
capital or from earnings available for distribution to shareholders), the amount
of One Hundred Dollars ($100.00) for each share of the Series A Preferred Stock,
plus the cash value  determined in accordance  with Section 2 above of all stock
dividends accrued and unpaid at the applicable rate on each such share up to the
date  fixed  for  distribution,  before  any  distribution  shall be made to the
holders of shares of Common Stock or any other capital stock of the  Corporation
ranking (as to any such distribution) junior to the Series A Preferred Stock. If
upon any liquidation,  dissolution or winding up of the Corporation,  the assets
distributable  among the holders of shares of the Series A  Preferred  Stock and
all  other  classes  and  series  of  preferred  stock  ranking  (as to any such
distribution)  on a parity with the Series A Preferred Stock are insufficient to
permit the payment in full to the holders of all such shares of

                                       -3-
<PAGE>
all preferential amounts payable to all such holders,  then the entire assets of
the  Corporation  thus  distributable  shall be  distributed  ratably  among the
holders of the shares of the Series A Preferred Stock and such other classes and
series of preferred stock ranking (as to any such distribution) on a parity with
the Series A Preferred Stock in proportion to the respective  amounts that would
be payable per share if such assets were sufficient to permit payment in full.

         (b) For  purposes of this  Section 3, a  distribution  of assets in any
dissolution,  winding up or liquidation  shall not include (i) any consolidation
or merger of the Corporation with or into any other corporation or other entity,
(ii)  any  dissolution,   liquidation,  winding  up  or  reorganization  of  the
Corporation  immediately  followed by reincorporation of another  corporation or
other entity or (iii) a sale or other disposition of all or substantially all of
the  Corporation's  assets to another  corporation  or other  entity;  PROVIDED,
HOWEVER,  that, in each case,  effective provision is made in the certificate of
incorporation  of the resulting and surviving  corporation  or otherwise for the
protection  of the  relative  rights of the  holders  of shares of the  Series A
Preferred Stock.

         (c) After the payment of the full  preferential  amounts  provided  for
herein  to the  holders  of  shares  of the  Series A  Preferred  Stock or funds
necessary for such payment have been set aside in trust for the holders thereof,
such  holders  shall be  entitled  to no other or further  participation  in the
distribution of the assets of the Corporation.

         Section 4. CONVERSION AND REDEMPTION OF SERIES A PREFERRED STOCK.

         (a) Each  holder of Series A  Preferred  Stock  shall  have the  right,
exercisable  at any time and from time to time during the period  commencing  on
the date that is ninety (90) days after the Closing  Date and ending on the date
that is two years after the Closing Date (the "Mandatory  Conversion  Date"), to
convert  any or all of the Series A  Preferred  Stock  owned by such  holder for
shares of Common  Stock,  at a conversion  rate  determined by  multiplying  the
number of shares of Series A Preferred Stock to be converted by a fraction,  the
numerator of which shall equal one hundred (100) and the denominator of which (a
"Denominator")  shall equal (i) the current market price per share of the Common
Stock (determined as provided in Section 5) as of the Closing Date (such current
market price being referred to herein as the "Closing Price"), if the applicable
Conversion  Date (as defined  below) occurs on or before the 119th day following
the Closing  Date,  (ii) the lessor of (A) 100% of the Closing  Price or (B) the
current  market  price per share of Common  Stock  (determined  as  provided  in
Section 5) as of the applicable  Conversion  Date, if the applicable  Conversion
Date  occurs on or after the 120th day after the  Closing  Date and on or before
the  179th day after  the  Closing  Date or (iii) the  lesser of (A) 100% of the
Closing Price

                                       -4-

<PAGE>
and (ii) 85% of the current  market price per share of Common Stock  (determined
as  provided  in  Section  5) as of  the  applicable  Conversion  Date  for  any
Conversion  Date  occurring  on or after the 180th day after the  Closing  Date,
subject to adjustment and the conditions described herein.

                  (b) (i) Any holder of shares of the Series A  Preferred  Stock
         electing to convert shares  thereof  pursuant to Section 4(a) shall (A)
         transmit by facsimile,  for receipt on the proposed date of conversion,
         a copy of a fully completed and executed notice of conversion  ("Notice
         of  Conversion") to the Corporation at the office of the Corporation or
         its  designated  transfer  agent (the  "Transfer  Agent"),  in the form
         attached as Exhibit A hereto, and (B) surrender to a common carrier for
         delivery to the office of the  Corporation or the Transfer  Agent,  the
         original  certificates  representing the Series A Preferred Stock being
         converted  (the  "Preferred  Stock  Certificates"),  duly  endorsed for
         cancellation. The Corporation shall, upon the timely written request of
         a holder of shares of the Series A Preferred Stock, promptly provide in
         writing to such holder,  via facsimile  transmission,  the  appropriate
         numbers for the Corporation and the Transfer Agent to be used to effect
         an election in accordance with this subparagraph (i).

                  (ii) Upon  receipt by the  Corporation  of  transmission  of a
         facsimile copy of such Notice of Conversion,  the Corporation  shall as
         soon as practicable  (but in no event later than 12:00 noon on the next
         business day after receipt thereof) send, via facsimile, a confirmation
         of receipt of such Notice of  Conversion  to such  holder,  which shall
         specify that the Notice of  Conversion  has been  received and the name
         and telephone  number of a contact person at the  Corporation  whom the
         holder should contact regarding information related to such conversion.
         Upon  receipt  by  the   Corporation  or  the  Transfer  Agent  of  the
         certificate(s)  representing  the shares of Series A Preferred Stock to
         be   converted   pursuant   to  such  Notice  of   Conversion   (or  an
         indemnification   undertaking   in  form   and   substance   reasonably
         satisfactory to the Corporation with respect to such shares in the case
         of their  loss,  theft or  destruction)  together  with the  originally
         executed  and  completed   Notice  of  Conversion  (such  date  of  the
         Corporation's receipt of all such documents being referred to herein as
         the "Final  Receipt  Date"),  the  Corporation  or  Transfer  Agent (as
         applicable) shall, as soon as possible on or after the applicable Final
         Receipt  Date,  but in any event within two (2) business days after the
         applicable  Final Receipt Date, issue and surrender to a common carrier
         for either  overnight  delivery  (if  delivery is to be made inside the
         United  States)  or two (2) day  delivery  (if  delivery  is to be made
         outside the United  States) to such holder at the address  specified in
         the Notice of  Conversion,  a  certificate  for the number of shares of
         Common  Stock to which such  holder  shall be entitled as in respect of
         the related conversion. In the

                                       -5-

<PAGE>



         event of a partial  conversion  of shares of Series A  Preferred  Stock
         represented by  certificate(s)  delivered to the Corporation in respect
         of any conversion, the Corporation will return to the applicable holder
         a certificate  representing such holder's  remaining shares of Series A
         Preferred Stock that were not so converted.  In the case of any dispute
         between the  Corporation  and such holder as to the  calculation of the
         applicable  Conversion  Price  evidenced  by a notice to such effect (a
         "Dispute Notice")  delivered to the Corporation by such holder prior to
         the Final Receipt Date,  the  Corporation  shall promptly issue to such
         holder the number of shares of Common  Stock that is not  disputed  and
         shall submit the disputed calculations to its outside accountant within
         two (2) business  days after the Final Receipt  Date.  The  Corporation
         shall cause such accountant to perform the  calculations and notify the
         Corporation  and the  holder  of the  results  no  later  than  two (2)
         business days after the date that such outside  accountant is delivered
         a copy of such holder's  Dispute Notice by the Corporation  pursuant to
         the preceding sentence.  Such accountant's  calculation shall be deemed
         conclusive  and  binding  on the  Corporation  and such  holder  absent
         manifest error.

                  (iii)  The  effective  date of a  particular  conversion  (the
         "Conversion  Date") other than pursuant to Section 4(c) shall be deemed
         to be the date on which  the  advance  copy of the  related  Notice  of
         Conversion  in respect of such  conversion  is  received  by either the
         Corporation or the Transfer Agent by facsimile transmission as provided
         in  paragraph  (ii) above,  provided  that (A) such advance copy of the
         Notice of Conversion is transmitted by facsimile to and received by the
         Corporation before 11:59 p.m., New York City time, on such date and (B)
         the original certificates  representing the Series A Preferred Stock to
         be converted (or an  indemnification  undertaking in form and substance
         reasonably  satisfactory to the Corporation with respect to such shares
         in the case of their loss,  theft or  destruction),  together  with the
         originally executed and completed Notice of Conversion, are surrendered
         by depositing such  certificates and Notice of Conversion with a common
         carrier,  as provided  above,  and received by the  Corporation  or the
         Transfer Agent on or before the second (2nd) business day following the
         date that the related  advance copy of the related Notice of Conversion
         is received by the Corporation or the Transfer Agent. In the event that
         all such documents are not received  within two (2) business days after
         such date, such Notice of Conversion  shall be deemed null and void and
         no conversion of Series A Preferred Stock shall be effected thereby.

                  (iv) As of any Conversion Date, the person or persons entitled
         to receive  the shares of the Common  Stock  issuable  upon the related
         conversion  of shares  of Series A  Preferred  Stock  pursuant  to this
         Section 4 shall be treated

                                       -6-
<PAGE>
         for all  purposes  as the  record  holder or  holders  of the shares of
         Common Stock issuable in respect of such  conversion on said date. From
         and after the  Conversion  Date in respect  of such  shares of Series A
         Preferred  Stock,  all such shares of Series A Preferred Stock shall be
         deemed  to have been  converted  into  shares  of  Common  Stock at the
         applicable  conversion  rate, all stock dividends on such shares of the
         Series A Preferred  Stock shall cease to accrue,  and all rights of the
         holders  thereof  as holders of Series A  Preferred  Stock,  except the
         right to  receive  all  accrued  and  unpaid  stock  dividends  to such
         Conversion  Date at the  applicable  rate for such  shares  of Series A
         Preferred  Stock and the  right to  receive  certificates  representing
         shares  of  Common  Stock  issuable  upon  conversion  of  such  shares
         (including,  without limitation, with respect to such stock dividends),
         shall cease and  terminate,  such  shares of Series A  Preferred  Stock
         shall not  thereafter  be  transferred  (except with the consent of the
         Corporation)  on the books of the Corporation and such shares shall not
         be deemed to be outstanding for any purpose whatsoever. The rights of a
         holder to elect to convert  shares of Series A  Preferred  Stock  under
         this Section 4(a) and 4(b) shall cease and terminate  immediately after
         the Mandatory Conversion Date.

         (c) Subject to Section  4(d), to the extent that any shares of Series A
Preferred  Stock held by a holder  thereof have not been  converted  pursuant to
Sections 4(a) and 4(b) as of the Mandatory Conversion Date, such holder shall be
deemed to have  elected to convert such  remaining  shares of Series A Preferred
Stock as of the Mandatory  Conversion  Date (without any action required by such
holder) and the  Corporation  shall issue  shares of Common Stock to such holder
and satisfy its other  obligations  under Section 4(a) and (b) as if such holder
had  elected  to  convert  such  remaining  shares of Series A  Preferred  Stock
pursuant to Sections 4(a) and 4(b) as of the Mandatory Conversion Date.

         (d) Notwithstanding  anything herein to the contrary, in the event that
(i) a holder of Series A Preferred  Stock elects (or is deemed to have  elected)
to convert shares of Series A Preferred Stock pursuant to Sections 4(a) and 4(b)
or  pursuant  to  Section  4(c) for  which a  Denominator  that is less than the
Closing Price is utilized in the  calculation  (pursuant to Section 4(a)) of the
number of shares of Common Stock to be issued in such  conversion  and (ii) such
conversion  would  result  in  such  holder  receiving,  as  a  result  of  such
conversion,  a number of shares of Common Stock that, together with other shares
of Common Stock  issued to such holder (or any  affiliate of such holder) in any
prior conversion(s) of Series A Preferred Stock that utilized a Denominator that
was less than the Closing Price in the calculation (pursuant to Section 4(a)) of
the  number of shares of  Common  Stock to be issued in such  conversion,  would
equal or exceed  twenty  percent  (20%) of the  shares  of  Common  Stock of the
Corporation  outstanding  on the  Closing  Date (the  "Threshold  Amount"),  the
Corporation shall (i) issue to such holder the

                                       -7-

<PAGE>
number of shares of Common Stock otherwise  required to be issued to such holder
as  a  result  of  such  conversion   (including  any  shares  of  Common  Stock
representing  cumulative  stock dividends  accrued to the applicable  Conversion
Date pursuant to Section 2) LESS the number of shares of Common Stock  otherwise
issuable to such holder  pursuant to such  conversion in excess of the Threshold
Amount (the "Excess Shares") and (ii) shall remit to such holder, in lieu of the
Excess Shares, an amount of cash equal to the number of Excess Shares multiplied
by the current market price per share of Common Stock (determined as provided in
Section 5) determined as of such  Conversion  Date. Upon such issuance of Common
Stock and payment of such cash to the holder in lieu of the Excess  Shares,  the
Corporation's  obligations to such holder arising as a result of such conversion
(including  the  Corporation's  obligation  to pay  cumulative  stock  dividends
through the applicable Conversion Date) shall be deemed fully satisfied.

         (e)  No  fractional  shares  of  Common  Stock  or  scrip  representing
fractional  shares  shall be issued  upon  conversion  of shares of the Series A
Preferred Stock pursuant to this Section 4. If more than one share of the Series
A Preferred  Stock shall be surrendered  for conversion by the same holder,  the
number of full shares of Common  Stock which shall be issuable  upon  conversion
thereof shall be computed on the basis of the aggregate  number of shares of the
Series A Preferred  Stock so  surrendered.  Instead of any fractional  shares of
Common Stock which would  otherwise be issuable upon conversion of any shares of
the Series A Preferred  Stock,  the  Corporation  shall pay a cash adjustment in
respect of such  fraction in an amount equal to the same fraction of the closing
bid price for Common Stock  determined as of the last business day preceding the
Conversion  Date in respect of such  shares.  The closing bid price for such day
shall be the last  reported  bid price on the  American  Stock  Exchange,  or if
Common  Stock is not listed or  admitted  to trading  on such  exchange,  on the
principal  national  securities  exchange  on which  Common  Stock is  listed or
admitted to trading  or, if not listed or  admitted  to trading on any  national
securities  exchange,  the  closing  bid price of Common  Stock on NASDAQ or any
comparable  system.  If Common  Stock is not quoted on NASDAQ or any  comparable
system,  the Board of Directors of the Corporation shall in good faith determine
the current market price on such basis as it considers appropriate.

         (f) When shares of Series A Preferred  Stock are  converted  (or deemed
converted) by a holder pursuant to this Section 4, the Corporation shall pay any
documentary,  stamp or similar  issue or transfer tax due on the issue of Common
Stock upon such conversion.

         (g) The Corporation shall reserve at all times out of the Corporation's
authorized but unissued shares of Common Stock a sufficient  number of shares of
Common  Stock to permit the  conversion  of the then  outstanding  shares of the
Series A Preferred Stock pursuant to this Section 4 and such reserved

                                       -8-
<PAGE>
shares shall not be used for any other purpose. All shares of Common Stock which
may be issued upon conversion of shares of the Series A Preferred Stock pursuant
to this  Section 4 shall be validly  issued,  fully paid and  nonassessable.  In
order that shares of Common Stock may be issued upon conversion of shares of the
Series A Preferred  Stock,  the  Corporation  shall  comply with all  applicable
Federal and State  securities  laws and use its best efforts to list such shares
of Common  Stock to be issued upon  conversion  on each  securities  exchange on
which Common Stock is listed.

         (h) The conversion  rate (and the components  thereof) in effect at any
time for  conversion of Series A Preferred  Stock into Common Stock  pursuant to
this Section 4 shall be subject to adjustment from time to time as follows:

                  (i) In the event that the Corporation shall (1) pay a dividend
         in shares of  Common  Stock to  holders  of  Common  Stock,  (2) make a
         distribution in shares of Common Stock to holders of Common Stock,  (3)
         subdivide the outstanding  shares of Common Stock into a greater number
         of shares of Common Stock, (4) combine the outstanding shares of Common
         Stock into a smaller  number of shares of Common Stock or (5) otherwise
         increase or decrease the number of  outstanding  shares of Common Stock
         through  reclassification  or any other  event  similar  to the  events
         described in clauses (1) through (4) above,  the  conversion  rate (and
         the  components   thereof)  in  effect   pursuant  to  this  Section  4
         immediately  prior to such  action  shall  be  adjusted  to the  extent
         required  to give  effect to the  impact of any such  event so that the
         holder  of any  shares  of the  Series  A  Preferred  Stock  thereafter
         surrendered for conversion pursuant to this Section 4 shall be entitled
         to  receive  the number of shares of Common  Stock  which he would have
         owned immediately following such action had such shares of the Series A
         Preferred  Stock  been  converted   immediately  prior  thereto.   Such
         adjustment  shall be made  whenever  any event listed above shall occur
         and shall become effective (A) immediately after the record date in the
         case of a dividend  or a  distribution  or other  applicable  event for
         which a record  date is used and (B)  immediately  after the  effective
         date in the case of a subdivision or  combination  or other  applicable
         event for which a record date is not used.

                  (ii) In case the Corporation  shall  distribute to all holders
         of the Common  Stock  shares of any class of capital  stock  other than
         Common  Stock,  evidences of  indebtedness  or other assets (other than
         non-extraordinary  cash dividends out of current or retained earnings),
         or shall distribute to substantially all holders of Common Stock rights
         or warrants to  subscribe  for  securities,  then in each such case the
         number of shares of the  Common  Stock  into  which  each  share of the
         Series A Preferred  Stock  shall be  converted  shall be adjusted  (and
         appropriate  adjustments  shall be made to the  component  parts of the
         applicable

                                       -9-

<PAGE>
         conversion rate) so that such number shall equal the number  determined
         by  multiplying  the  number of shares of Common  Stock into which such
         share of the Series A Preferred Stock was convertible immediately prior
         to the date of such  distribution  by a fraction of which the numerator
         shall be the  current  market  price of  Common  Stock  (determined  as
         provided in Section 5) on the record date mentioned below, and of which
         the  denominator  shall be such current  market price of Common  Stock,
         less the then fair  market  value (as  determined  in good faith by the
         Board of Directors of the  Corporation,  whose  determination  shall be
         conclusive  evidence of such fair  market  value) of the portion of the
         assets  so  distributed  or of such  subscription  rights  or  warrants
         applicable to one share of Common Stock.  Such adjustment  shall become
         effective  immediately  after the record date for the  determination of
         the holders of Common Stock entitled to receive such distribution.

                  (iii) The Corporation  shall provide at least 10 business days
         advance  notice to  holders of Series A  Preferred  Stock of any record
         date or other applicable date for determining  shareholders entitled to
         participate  in any of the events  described  in this  Section  4(h) or
         other  similar  events not  described  in this Section 4(h) which would
         have a dilutive  effect on the Series A  Preferred  Stock or the Common
         Stock into which the Series A Preferred Stock is convertible.

         (i) No adjustment in the conversion rate (or its component parts) under
this  Section  4 shall be  required  until  cumulative  adjustments  result in a
concomitant  change of 1% or more of the  conversion  rate as in effect prior to
the  last  adjustment  of the  conversion  rate;  PROVIDED,  HOWEVER,  that  any
adjustments  which by reason of this  Section  4(i) 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. No adjustment to the
conversion rate shall be made for non-extraordinary cash dividends.

         (j) In the event that,  as a result of an  adjustment  made pursuant to
Section 4(h), the holder of any share of the Series A Preferred Stock thereafter
surrendered  for  conversion  shall  become  entitled  to receive  any shares of
capital stock of the Corporation  other than shares of Common Stock,  thereafter
the number of such other shares so receivable  upon  conversion of any shares of
the Series A 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 with
respect to the Common Stock contained in this Section 4.

         (k) The Corporation may make such increases in the conversion  rate, in
addition to those  required by Sections  4(h)(i) and (ii), as it considers to be
advisable in order that any event  treated for Federal  income tax purposes as a
dividend

                                      -10-

<PAGE>
of stock or stock rights shall not be taxable to the recipients thereof.

         (l)  Whenever  the  conversion  rate  (or any  components  thereof)  is
adjusted  pursuant to this Section 4, the Corporation shall promptly mail to all
holders  of record of shares  of the  Series A  Preferred  Stock a notice of the
adjustment  and shall  cause to be  prepared a  certificate  signed by the chief
financial officer of the Corporation or, if requested in writing by holders of a
majority  of the  shares of  Series A  Preferred  Stock  then  outstanding,  the
Corporation's  outside  accountants  or  a  reputable  investment  banking  firm
selected by the Corporation  setting forth the adjusted conversion rate (and the
component  parts  thereof)  and a brief  statement of the facts  requiring  such
adjustment and the  computation  thereof.  Such  certificate  shall forthwith be
filed with each transfer agent for the shares of the Series A Preferred Stock.

         (m) If any of the following shall occur:  (i) any  reclassification  or
change of outstanding  shares of Common Stock issuable upon conversion of shares
of the Series A Preferred  Stock (other than a change in par value,  or from par
value to no par value,  or from no par value to par  value,  or as a result of a
subdivision  or  combination),  (ii) any  consolidation  or  merger to which the
Corporation  is a party  other  than a merger  in which the  Corporation  is the
continuing  corporation and which does not result in any reclassification of, or
change (other than a change in name,  or par value,  or from par value to no par
value,  or from no par value to par value,  or as a result of a  subdivision  or
combination)  in,  outstanding  shares  of  Common  Stock or  (iii)  any sale or
conveyance  of all or  substantially  all of the  property  or  business  of the
Corporation  as  an  entirety,  then  the  Corporation,  or  such  successor  or
purchasing  corporation,  as the case may be, shall, as a condition precedent to
such  reclassification,  change,  consolidation,  merger,  sale  or  conveyance,
provide in its certificate of  incorporation or other charter document that each
share of the Series A Preferred Stock shall be convertible  under this Section 4
into the kind and amount of shares of  capital  stock and other  securities  and
property  (including  cash)  receivable  upon  such  reclassification,   change,
consolidation, merger, sale or conveyance by a holder of the number of shares of
Common Stock deliverable upon conversion of such share of the Series A Preferred
Stock immediately prior to such reclassification, change, consolidation, merger,
sale or conveyance.  Such certificate of incorporation or other charter document
shall provide for adjustments and protection which shall be as nearly equivalent
as may be practicable to the adjustments  provided for in this Section 4. If, in
the case of any such  consolidation,  merger,  sale or conveyance,  the stock or
other securities and property (including cash) receivable  thereupon by a holder
of  Common  Stock  includes  shares of  capital  stock or other  securities  and
property of a corporation other than the successor  purchasing  corporation,  as
the case may be, in such  consolidation,  merger,  sale or conveyance,  then the
certificate of incorporation or other charter document of such other

                                      -11-

<PAGE>
corporation shall contain such additional provisions to protect the interests of
the holders of shares of the Series A Preferred  Stock as the Board of Directors
of  the  Corporation  shall  reasonably  consider  necessary  by  reason  of the
foregoing.  The  provision  of  this  Section  4(m)  shall  similarly  apply  to
successive consolidations, mergers, sales or conveyances.

         (n) No sooner than fifteen (15)  business  days nor later than five (5)
business days prior to the consummation of a transaction  referred to in clauses
(ii) or (iii) of  Section  4(m) (a  "Major  Transaction"),  but not prior to the
public  announcement of such Major  Transaction,  the Corporation  shall deliver
written  notice (a "Notice  of Major  Transaction")  to each  holder of Series A
Preferred Stock,  which Notice of Major Transaction shall be deemed to have been
delivered to the holder one (1) business day after the Corporation's  sending of
such notice (for overnight delivery) by a common carrier, if such delivery is to
be made in the United States,  or two (2) business days after the  Corporation's
sending of such notice (for two (2) day  delivery)  by common  carrier,  if such
notice is to be  delivered  outside  the  United  States.  Such  Notice of Major
Transaction  shall indicate the amount and type(s) of consideration  (the "Major
Transaction  Consideration")  the  holders  of Series A  Preferred  Stock  would
receive  for their  shares  of Series A  Preferred  Stock in the  related  Major
Transaction.  Such holder may elect to redeem all or a portion of such  holder's
shares of Series A Preferred Stock for an amount in cash equal to $125 per share
of Series A Preferred Stock held by such holder to be so redeemed in lieu of the
Major  Transaction  Consideration or other securities and/or property that would
otherwise  be payable to such  holder  pursuant  to Section  4(m).  A holder may
exercise  such  election by  delivering  written  notice of such election to the
Corporation,  together  with  certificates  for the shares of Series A Preferred
Stock to be redeemed in connection with such election,  within five (5) business
days of the holder's receipt of the related Notice of Major  Transaction,  which
notice  shall be deemed  given one (1)  business day after the holder sends such
notice  (together  with  such  certificates)  from the  United  States by common
carrier for  overnight  delivery or two (2) business days after the holder sends
such notice (together with such  certificates) from outside the United States by
common  carrier  for  two  (2)  day  delivery.  In the  event  that  such  Major
Transaction  is not  completed  within  fifteen  (15)  business  days  after the
Corporation is given a holder's related notice of election pursuant to the prior
sentence,  such  election  shall  be null and  void  and the  Corporation  shall
promptly  return the  certificate(s)  representing  the Series A Preferred Stock
delivered by such holder to such holder;  provided,  that the  Corporation  will
comply with the notice provisions of this Section 4(n) with respect to any later
consummation  of such Major  Transaction.  This  Section 4(n) shall not apply in
respect of any Major Transaction that occurs after the second anniversary of the
Closing Date.

         (o) (i) After the occurrence of a Change in Control (as defined below),
other than in connection with a Major

                                      -12-

<PAGE>
         Transaction,  each  holder of Series A  Preferred  Stock shall have the
         right,  at such holder's  option,  to require the Corporation to redeem
         all or a  portion  of such  holder's  Series A  Preferred  Stock for an
         amount per share in cash  equal to the  greater of (A) $125 and (B) the
         product of the aggregate  number of shares of Common Stock into which a
         share  of  Series  A  Preferred  Stock is  convertible  (assuming  such
         conversion  were to occur on the last day preceding the effective  date
         for the Change of Control)  multiplied by the current  market price per
         share of Common Stock  (determined  as provided in Section 5) as of the
         last date  preceding the effective  date of such Change of Control.  As
         used in this  Section  4(o),  a "Change in Control"  shall be deemed to
         have  occurred  at such  time as  either  Douglas  R. Eger or Thomas M.
         Fitzgerald cease to be either a director or officer of the Corporation.
         The rights of holders of Series A Preferred  Stock  under this  Section
         4(o) shall not apply in respect  of any Change of Control  that  occurs
         after the first anniversary of the Closing Date.

                  (ii) The  Corporation  shall  provide  each holder of Series A
         Preferred  Stock with written notice of the occurrence of any Change of
         Control (a "Change of Control  Notice")  within two (2)  business  days
         after the occurrence of such Change of Control. Each holder may require
         the  Corporation to redeem all or a portion of such holder's  shares of
         Series A Preferred  Stock  pursuant to this Section 4(o) by  delivering
         written  notice (a "Notice of  Redemption  at Option of Holder") to the
         Corporation  to such effect within ten (10) business days after receipt
         of the applicable Change of Control Notice,  which Notice of Redemption
         at  Option of Holder  shall be  deemed to have been  delivered  one (1)
         business day after such holder's sending, if such notice is sent within
         the United States for overnight  delivery by a common  carrier,  or two
         (2) business days after such holder's  sending,  if such notice is sent
         from  outside  the United  States by two (2) day  delivery  by a common
         carrier.  Each such  Notice  of  Redemption  at Option of Holder  shall
         indicate  the  number of shares of Series A  Preferred  Stock that have
         been selected by such holder for redemption.

                  (iii)  Each  holder  submitting  certificate(s)   representing
         shares of Series A Preferred Stock for redemption  under this Paragraph
         4(o)  shall  send such  holder's  Preferred  Stock  Certificates  to be
         redeemed to the  Corporation or its Transfer Agent and the  Corporation
         shall pay the applicable  redemption price to that holder within thirty
         (30)  business  days after the  Corporation's  receipt of such holder's
         Notice of Redemption  at Option of Holder;  provided that such holder's
         certificate(s)  representing  shares of Series A Preferred  Stock to be
         redeemed (or an indemnification undertaking with respect to such shares
         in the case of their  loss,  theft or  destruction)  shall have been so
         delivered to the Corporation or its Transfer Agent.

         Section 5.  CALCULATIONS  OF CURRENT MARKET PRICE OF COMMON STOCK.  For
purposes of calculations  relating to the Series A Preferred Stock that refer to
the current market price per share of Common Stock, the current market price per
share of Common  Stock on or as of any day shall be deemed to be the  average of
the closing bid prices for the ten (10) consecutive trading days ending the last
trading day before the day in question. The closing bid price for each day shall
be the last  reported bid price on the  American  Stock  Exchange,  or if Common
Stock is not listed or admitted to trading on such  exchange,  on the  principal
national  securities  exchange  on which  Common  Stock is listed or admitted to
trading  or, if not listed or  admitted  to trading on any  national  securities
exchange,  the  closing  bid price of Common  Stock on NASDAQ or any  comparable
system, or if Common Stock is not quoted on NASDAQ or any comparable system, the
closing bid price as furnished by any two members of the National Association of
Securities Dealers,  Inc. selected from time to time by the Corporation for that
purpose.  If Common Stock is not so quoted on NASDAQ or any  comparable  system,
the Board of Directors of the  Corporation  shall  reasonably  and in good faith
determine  the current  market price on such basis as it considers  appropriate.
For  example,  in the event that the  current  market  price per share of Common
Stock is to be determined as of a Conversion  Date, the current market price per
share of Common Stock shall equal the average of the last  reported bid price as
reported by the American  Stock  Exchange for the ten (10)  consecutive  trading
days ending the last trading day before such  Conversion Date (assuming that the
Common Stock is listed and admitted for trading on the American  Stock  Exchange
and a  reported  bid price for  Common  Stock is  placed on the  American  Stock
Exchange on each such trading day).

         Section 6. LIMITATIONS. (a) In addition to any other rights provided by
applicable  law,  so long as any  shares  of the  Series A  Preferred  Stock are
outstanding,  the Corporation  shall not,  without the affirmative  vote, or the
written consent as provided by law, of the holders of at least  two-thirds (2/3)
of the outstanding shares of the Series A Preferred Stock,  voting as a separate
class,

                  (i) create,  authorize or issue any class or series of capital
         stock,  or  rights  to  subscribe  to  or  acquire,   or  any  security
         convertible  into,  any class or series of capital  stock ranking as to

                  voting rights, prior to the Series A Preferred Stock;
                  or

                  (ii) amend, alter or appeal, whether by merger,  consolidation
         or otherwise, any of the provisions of the Certificate of Incorporation
         (including  this  Certificate  of  Designation)  that would  change the
         preferences,  rights or powers  with  respect to the Series A Preferred
         Stock so as to affect the Series A Preferred Stock adversely.

         (b) In addition to any other rights provided by applicable law, so long
as any shares of the Series A Preferred Stock are  outstanding,  the Corporation
shall not,  without the affirmative  vote, or the written consent as provided by
law, of the holders of at least  two-thirds  (2/3) of the outstanding  shares of
the Series A  Preferred  Stock,  voting as a separate  class,  issue or agree to
issue any Common Stock or any security  convertible  or otherwise  exchangeable,
directly or  indirectly,  for Common Stock if such shares of Common Stock are to
be issued,  or such  convertible  securities are to be converted to or exchanged
for shares of Common  Stock,  at a price per share less than the current  market
price for the Common Stock  (determined  as provided in Section 5) as of the day
immediately  preceding  the date of the  issuance of such  Common  Stock or such
convertible or exchangeable  security (as the case may be);  provided,  however,
that the restrictions contained in this paragraph (b) shall not apply (i) to the
issuance of any such convertible or exchangeable securities that are convertible
or  exchangeable  at a fixed price (and not a floating price) per share equal to
or greater than the current  market price for the Common  Stock  (determined  as
provided  in  Section  5) as of the  date of  issuance  of such  convertible  or
exchangeable security, (ii) to the issuance of Common Stock and other securities
of the Corporation issuable upon the exercise or conversion of options, warrants
on other rights to purchase securities of the Corporation  outstanding as of the
date hereof,  (iii) to the issuance of any securities to officers,  directors or
employees of the Corporation or any of its subsidiaries, (iv) to the issuance of
any securities of the Corporation in an  underwritten  public offering or (v) to
any other  issuance  of  securities  after  the date  that is 90 days  after the
Closing  Date if the holders of Series A Preferred  Stock are first  delivered a
written notice (a "Right of First Refusal Notice") from the Corporation offering
such  holders on a PRO RATA basis the right to purchase  all or a portion of the
related  securities  at the same price  (and on the same  terms and  conditions,
offered to other  proposed  investors  (which notice shall set forth such price,
terms and  conditions).  In the event that the  Corporation  delivers a Right of
First Refusal Notice to any holder of Series A Preferred  Stock,  the failure by
such holder to commit in writing to purchase  such  holder's pro rata portion of
the securities  identified in such Right of First Refusal Notice within five (5)
business days of delivery thereof may be deemed by the Corporation to constitute
such  holder's  determination  not  to  so  purchase  such  securities  and  the
Corporation shall then be

                                      -15-

<PAGE>
permitted  to sell such  securities  to other  investors at the price and on the
terms and conditions set forth in such notice. The rights of holders of Series A
Preferred   Stock  under  this  paragraph  (b)  shall  terminate  on  the  first
anniversary of the Closing Date.

         (c)  Notwithstanding  the  foregoing,  except as otherwise  required by
applicable law,  nothing herein contained shall require a vote or consent of the
holders of Series A Preferred Stock in connection with any increase in the total
number of authorized  shares of Common Stock.  The holders of Series A Preferred
Stock shall not be entitled to vote on any matter except (i) as provided in this
Section 6 and (ii) as required by law.

         Section  7.  LOST OR  STOLEN  CERTIFICATES.  Upon  (i)  receipt  by the
Corporation  from a holder of evidence  satisfactory  to the  Corporation of the
loss, theft,  destruction of any certificate(s)  representing shares of Series A
Preferred  Stock  and of an  indemnification  undertaking  by the  holder to the
Corporation  that is reasonably  satisfactory  to the  Corporation  or (ii) upon
surrender and  cancellation of  certificate(s)  representing  shares of Series A
Preferred  Stock that have been  mutilated,  the  Corporation  shall execute and
deliver  to such  holder  new  certificate(s)  representing  shares  of Series A
Preferred Stock of like tenor and date.  However,  the Corporation  shall not be
obligated to re-issue such lost, stolen,  destroyed or mutilated  certificate(s)
representing shares of Series A Preferred Stock if such holder contemporaneously
requests the Corporation to convert such shares of Series A Preferred Stock into
shares of Common  Stock or  otherwise  redeem such shares  pursuant to the terms
hereof.

                       SHEFFIELD MEDICAL TECHNOLOGIES INC.

                         (Pursuant to Section 151 of the
                General Corporation Law of the State of Delaware)

                              ---------------------

         Sheffield  Medical  Technologies  Inc.,  a  corporation  organized  and
existing  under  the  General  Corporation  Law of the  State of  Delaware  (the
"Corporation"),  hereby  certifies that the following  resolution was adopted by
the Board of Directors of the Corporation:

         RESOLVED,  that  pursuant  to the  authority  expressly  granted to and
vested in the Board of Directors of the  Corporation  (the "Board of Directors")
by the provisions of the Certificate of  Incorporation  of the Corporation  (the
"Certificate of Incorporation"),  there hereby is created,  out of the 3,000,000
shares of preferred stock of the Corporation authorized in Article FOURTH of the
Certificate of  Incorporation  (the  "Preferred  Stock"),  a series of Preferred
Stock consisting of 40,800 shares, which series shall have the following powers,
designations, preferences and relative, participating, optional or other rights,
and the following  qualifications,  limitations and restrictions (in addition to
the powers, designations,  preferences and relative, participating,  optional or
other rights, and the qualifications, limitations and restrictions, set forth in
the Certificate of Incorporation which are applicable to the Preferred Stock).

         Section 1.  DESIGNATION AND AMOUNT.  The shares of such series shall be
designated as "Series A Cumulative  Convertible Redeemable Preferred Stock" (the
"Series A Preferred  Stock") and the  authorized  number of shares  constituting
such series shall be 40,800. The par value of the Series A Preferred Stock shall
be $.01 per share.

<PAGE>

         Section 2. DIVIDENDS.

         Subject  to  Section  4(d),  the  holders  of  shares  of the  Series A
Preferred  Stock will be entitled to  receive,  when,  as and if declared by the
Board of  Directors,  cumulative  stock  dividends on the shares of the Series A
Preferred Stock,  payable in shares of the Corporation's  common stock, $.01 par
value per share ("Common Stock"), at the rate per share of 7.0% per annum of the
original  $100.00  purchase price per share of the Series A Preferred Stock, and
no more.  Such stock  dividends shall be cumulative from the date of the initial
issuance of shares of Series A Preferred  Stock (the "Closing Date") or the most
recent date on which the full amount of accrued stock  dividends have been paid,
as the case may be, on the Series A Preferred Stock by the Corporation.  Subject
to, and as provided  in,  Section 4, the  Corporation  shall pay all  cumulative
stock  dividends  on the shares of Series A Preferred  Stock held by a holder on
the Conversion  Date (as defined below) in respect of such holder's  election to
convert  Series A Preferred  Stock.  The number of shares of Common  Stock to be
issued as cumulative stock dividends on any such Conversion Date shall equal the
cash value of such cumulative  dividends divided by the current market price per
share  of  Common  Stock  (determined  as  provided  in  Section  5) as of  such
Conversion Date. The cash value of stock dividends payable on shares of Series A
Preferred  Stock  for any full  annual  dividend  period  shall be  computed  by
multiplying  the original  $100.00  purchase  price per share by 7.0%.  The cash
value of  dividends  payable on shares of the Series A  Preferred  Stock for any
period less than a full annual dividend period shall be computed on the basis of
a 360-day year of twelve  30-day months and the actual number of days elapsed in
the period for which payable.

         If stock  dividends are not paid in full, or declared in full, upon the
shares of the Series A Preferred  Stock and shares of any other  preferred stock
ranking on a parity as to payment of stock dividends with the Series A Preferred
Stock,  all dividends  declared upon shares of the Series A Preferred  Stock and
any other  preferred  stock ranking on a parity as to payment of dividends  with
the Series A Preferred  Stock shall be paid or declared  PRO RATA so that in all
cases the  amount  of  dividends  paid or  declared  per  share on the  Series A
Preferred  Stock and such other shares of preferred stock ranking on a parity as
to payment of  dividends  with the Series A  Preferred  Stock shall bear to each
other the same ratio  that  accumulated  stock  dividends  per share,  including
dividends accrued or in arrears, if any, on the shares of the Series A Preferred
Stock and such other  shares of  preferred  stock bear to each other.  Except as
provided in the preceding  sentence,  unless full cumulative  stock dividends on
the shares of the Series A  Preferred  Stock have been paid or declared in full,
no dividends  (other than  dividends in shares of Common Stock,  or in shares of
any other  capital  stock of the  Corporation

                                      -2-
<PAGE>
ranking  junior to the Series A Preferred  Stock as to payment of dividends  and
distribution of assets upon liquidation) shall be paid or declared and set aside
for payment or other  distribution  upon the Common Stock or, except as provided
above, on any other capital stock of the  Corporation  ranking junior to or on a
parity with the Series A Preferred  Stock as to dividends,  nor shall any shares
of Common Stock or shares of any other capital stock of the Corporation  ranking
junior to or on a parity with the Series A Preferred  Stock as to  dividends  be
redeemed,  purchased or otherwise acquired for any consideration (or any payment
made to or available  for a sinking fund for the  redemption of any such shares)
by the  Corporation or any subsidiary of the  Corporation  (except by conversion
into or exchange for shares of capital stock of the  Corporation  ranking junior
to the Series A Preferred Stock as to dividends and  distribution of assets upon
liquidation).  Holders of shares of the Series A  Preferred  Stock  shall not be
entitled to any dividends,  whether payable in capital stock,  cash or property,
in excess of full accrued and cumulative stock dividends as herein provided.  No
interest or sum of money in lieu of interest  shall be payable in respect of any
stock dividend payment or payments on the shares of the Series A Preferred Stock
that may be in arrears; provided,  however, that if, on an applicable Conversion
Date (as defined  herein),  stock dividends that would have been payable on such
date  are not paid  solely  due to the  failure  of the  Corporation's  Board of
Directors to declare such dividends, then the rate of conversion of the Series A
Preferred  Stock to be  converted on such  Conversion  Date shall be adjusted so
that the holders would receive the same amount of shares of Common Stock on such
Conversation Date as such holder would have received if the Corporation's  Board
of Directors had timely declared such stock dividends.

         The terms "accrued  dividends,"  "dividends  accrued" and "dividends in
arrears," whenever used herein with reference to shares of preferred stock shall
be deemed to mean an amount  which  shall be equal to  dividends  thereon at the
applicable  annual  dividend rates per share for the  respective  series thereof
from the  date or  dates on which  such  dividends  commence  to  accrue  to the
applicable  payment date less the amount of all  dividends  paid, or declared in
full and sums set aside for the payment  thereof,  upon such shares of preferred
stock.

         Section 3. LIQUIDATION RIGHTS.

         (a) In the event of any  liquidation,  dissolution or winding up of the
affairs of the  Corporation,  whether  voluntary or otherwise,  after payment or
provision for payment of the debts and other liabilities of the Corporation, the
holders of shares of the Series A Preferred  Stock shall be entitled to receive,
in cash,  out of the  remaining  net  assets of the  Corporation  (whether  from
capital or from earnings available for distribution to

                                      -3-
<PAGE>

shareholders), the amount of One Hundred Dollars ($100.00) for each share of the
Series A Preferred  Stock,  plus the cash value  determined in  accordance  with
Section 2 above of all stock dividends accrued and unpaid at the applicable rate
on  each  such  share  up  to  the  date  fixed  for  distribution,  before  any
distribution shall be made to the holders of shares of Common Stock or any other
capital stock of the Corporation ranking (as to any such distribution) junior to
the Series A Preferred Stock. If upon any liquidation, dissolution or winding up
of the Corporation,  the assets distributable among the holders of shares of the
Series A Preferred  Stock and all other  classes and series of  preferred  stock
ranking  (as to any such  distribution)  on a parity with the Series A Preferred
Stock are  insufficient to permit the payment in full to the holders of all such
shares of all preferential amounts payable to all such holders,  then the entire
assets of the Corporation thus distributable  shall be distributed ratably among
the holders of the shares of the Series A Preferred Stock and such other classes
and series of preferred stock ranking (as to any such  distribution) on a parity
with the Series A Preferred  Stock in proportion to the respective  amounts that
would be payable per share if such assets were  sufficient to permit  payment in
full.

         (b) For  purposes of this  Section 3, a  distribution  of assets in any
dissolution,  winding up or liquidation  shall not include (i) any consolidation
or merger of the Corporation with or into any other corporation or other entity,
(ii)  any  dissolution,   liquidation,  winding  up  or  reorganization  of  the
Corporation  immediately  followed by reincorporation of another  corporation or
other entity or (iii) a sale or other disposition of all or substantially all of
the  Corporation's  assets to another  corporation  or other  entity;  PROVIDED,
HOWEVER,  that, in each case,  effective provision is made in the certificate of
incorporation  of the resulting and surviving  corporation  or otherwise for the
protection  of the  relative  rights of the  holders  of shares of the  Series A
Preferred Stock.

         (c) After the payment of the full  preferential  amounts  provided  for
herein  to the  holders  of  shares  of the  Series A  Preferred  Stock or funds
necessary for such payment have been set aside in trust for the holders thereof,
such  holders  shall be  entitled  to no other or further  participation  in the
distribution of the assets of the Corporation.


         Section 4. CONVERSION AND REDEMPTION OF SERIES A PREFERRED STOCK.

         (a) Each  holder of Series A  Preferred  Stock  shall  have the  right,
exercisable  at any time and from time to time during the period  commencing  on
the date that is ninety (90) days after the Closing  Date and ending on the date
that is two years after

                                      -4-
<PAGE>


the Closing Date (the "Mandatory Conversion Date"), to convert any or all of the
Series A Preferred  Stock owned by such holder for shares of Common Stock,  at a
conversion  rate  determined  by  multiplying  the  number of shares of Series A
Preferred  Stock to be  converted  by a fraction,  the  numerator of which shall
equal one hundred (100) and the  denominator  of which (a  "Denominator")  shall
equal (i) the current market price per share of the Common Stock  (determined as
provided in Section 5) as of the Closing Date (such  current  market price being
referred to herein as the "Closing  Price"),  if the applicable  Conversion Date
(as defined below) occurs on or before the 119th day following the Closing Date,
(ii) the lessor of (A) 100% of the Closing Price or (B) the current market price
per share of Common  Stock  (determined  as  provided  in  Section  5) as of the
applicable Conversion Date, if the applicable Conversion Date occurs on or after
the 120th day after the  Closing  Date and on or before  the 179th day after the
Closing  Date or (iii) the lesser of (A) 100% of the Closing  Price and (ii) 85%
of the current market price per share of Common Stock (determined as provided in
Section  5) as of  the  applicable  Conversion  Date  for  any  Conversion  Date
occurring  on or after  the  180th  day  after  the  Closing  Date,  subject  to
adjustment and the conditions described herein.

                  (b) (i) Any holder of shares of the Series A  Preferred  Stock
         electing to convert shares  thereof  pursuant to Section 4(a) shall (A)
         transmit by facsimile,  for receipt on the proposed date of conversion,
         a copy of a fully completed and executed notice of conversion  ("Notice
         of  Conversion") to the Corporation at the office of the Corporation or
         its  designated  transfer  agent (the  "Transfer  Agent"),  in the form
         attached as Exhibit A hereto, and (B) surrender to a common carrier for
         delivery to the office of the  Corporation or the Transfer  Agent,  the
         original  certificates  representing the Series A Preferred Stock being
         converted  (the  "Preferred  Stock  Certificates"),  duly  endorsed for
         cancellation. The Corporation shall, upon the timely written request of
         a holder of shares of the Series A Preferred Stock, promptly provide in
         writing to such holder,  via facsimile  transmission,  the  appropriate
         numbers for the Corporation and the Transfer Agent to be used to effect
         an election in accordance with this subparagraph (i).

                  (ii) Upon  receipt by the  Corporation  of  transmission  of a
         facsimile copy of such Notice of Conversion,  the Corporation  shall as
         soon as practicable  (but in no event later than 12:00 noon on the next
         business day after receipt thereof) send, via facsimile, a confirmation
         of receipt of such Notice of  Conversion  to such  holder,  which shall
         specify that the Notice of  Conversion  has been  received and the name
         and telephone  number of a contact person at the  Corporation  whom the
         holder should contact regarding information related to such conversion.

         Receipt  Date,  but in any event within two (2) business days after the
         applicable  Final Receipt Date, issue and surrender to a common carrier
         for either  overnight  delivery  (if  delivery is to be made inside the
         United  States)  or two (2) day  delivery  (if  delivery  is to be made
         outside the United  States) to such holder at the address  specified in
         the Notice of  Conversion,  a  certificate  for the number of shares of
         Common  Stock to which such  holder  shall be entitled as in respect of
         the related conversion.  In the event of a partial conversion of shares
         of Series A Preferred Stock represented by certificate(s)  delivered to
         the  Corporation in respect of any  conversion,  the  Corporation  will
         return  to  the  applicable  holder  a  certificate  representing  such
         holder's  remaining shares of Series A Preferred Stock that were not so
         converted.  In the case of any dispute between the Corporation and such
         holder  as to  the  calculation  of  the  applicable  Conversion  Price
         evidenced by a notice to such effect (a "Dispute Notice")  delivered to
         the  Corporation  by such holder prior to the Final Receipt  Date,  the
         Corporation shall promptly issue to such holder the number of shares of
         Common  Stock  that is not  disputed  and  shall  submit  the  disputed
         calculations  to its outside  accountant  within two (2) business  days
         after  the  Final  Receipt  Date.  The  Corporation  shall  cause  such
         accountant to perform the  calculations  and notify the Corporation and
         the holder of the results no later than two (2) business days after the
         date that such outside  accountant is delivered a copy of such holder's
         Dispute Notice by the Corporation  pursuant to the preceding  sentence.
         Such accountant's calculation shall be deemed conclusive and binding on
         the Corporation and such holder absent manifest error.

                  (iii)  The  effective  date of a  particular  conversion  (the
         "Conversion  Date") other than pursuant to Section 4(c) shall be deemed
         to be the date on which  the  advance  copy of the  related  Notice  of
         Conversion  in respect of such  conversion  is  received  by either the
         Corporation or the Transfer Agent by facsimile transmission as provided
         in  paragraph  (ii) above,  provided  that (A) such advance copy of the
         Notice of Conversion is transmitted by facsimile to and

                                      -6-
<PAGE>

         received by the  Corporation  before 11:59 p.m., New York City time, on
         such date and (B) the original  certificates  representing the Series A
         Preferred Stock to be converted (or an  indemnification  undertaking in
         form and substance  reasonably  satisfactory  to the  Corporation  with
         respect  to  such  shares  in  the  case  of  their   loss,   theft  or
         destruction),  together  with the  originally  executed  and  completed
         Notice of Conversion,  are surrendered by depositing such  certificates
         and Notice of Conversion with a common carrier,  as provided above, and
         received  by the  Corporation  or the  Transfer  Agent on or before the
         second (2nd)  business day following the date that the related  advance
         copy of the related Notice of Conversion is received by the Corporation
         or the Transfer  Agent.  In the event that all such  documents  are not
         received  within two (2) business days after such date,  such Notice of
         Conversion  shall be deemed null and void and no conversion of Series A
         Preferred Stock shall be effected thereby.

                  (iv) As of any Conversion Date, the person or persons entitled
         to receive  the shares of the Common  Stock  issuable  upon the related
         conversion  of shares  of Series A  Preferred  Stock  pursuant  to this
         Section 4 shall be treated  for all  purposes  as the record  holder or
         holders  of the  shares of Common  Stock  issuable  in  respect of such
         conversion on said date.  From and after the Conversion Date in respect
         of such shares of Series A Preferred Stock, all such shares of Series A
         Preferred  Stock shall be deemed to have been  converted into shares of
         Common Stock at the applicable  conversion rate, all stock dividends on
         such shares of the Series A Preferred Stock shall cease to accrue,  and
         all rights of the  holders  thereof  as  holders of Series A  Preferred
         Stock,  except  the right to  receive  all  accrued  and  unpaid  stock
         dividends  to such  Conversion  Date at the  applicable  rate  for such
         shares  of  Series  A   Preferred   Stock  and  the  right  to  receive
         certificates   representing   shares  of  Common  Stock  issuable  upon
         conversion of such shares (including,  without limitation, with respect
         to such stock  dividends),  shall cease and  terminate,  such shares of
         Series A Preferred  Stock shall not thereafter be  transferred  (except
         with the consent of the  Corporation)  on the books of the  Corporation
         and such shares shall not be deemed to be  outstanding  for any purpose
         whatsoever. The rights of a holder to elect to convert shares of Series
         A  Preferred  Stock  under this  Section  4(a) and 4(b) shall cease and
         terminate immediately after the Mandatory Conversion Date.

         (c) Subject to Section  4(d), to the extent that any shares of Series A
Preferred  Stock held by a holder  thereof have not been  converted  pursuant to
Sections 4(a) and 4(b) as of the Mandatory Conversion Date, such holder shall be
deemed to have elected to convert such remaining shares of Series A Preferred

                                      -7-
<PAGE>

Stock as of the Mandatory  Conversion  Date (without any action required by such
holder) and the  Corporation  shall issue  shares of Common Stock to such holder
and satisfy its other  obligations  under Section 4(a) and (b) as if such holder
had  elected  to  convert  such  remaining  shares of Series A  Preferred  Stock
pursuant to Sections 4(a) and 4(b) as of the Mandatory Conversion Date.

         (d) Notwithstanding  anything herein to the contrary, in the event that
(i) a holder of Series A Preferred  Stock elects (or is deemed to have  elected)
to convert shares of Series A Preferred Stock pursuant to Sections 4(a) and 4(b)
or  pursuant  to  Section  4(c) for  which a  Denominator  that is less than the
Closing Price is utilized in the  calculation  (pursuant to Section 4(a)) of the
number of shares of Common Stock to be issued in such  conversion  and (ii) such
conversion  would  result  in  such  holder  receiving,  as  a  result  of  such
conversion,  a number of shares of Common Stock that, together with other shares
of Common Stock  issued to such holder (or any  affiliate of such holder) in any
prior conversion(s) of Series A Preferred Stock that utilized a Denominator that
was less than the Closing Price in the calculation (pursuant to Section 4(a)) of
the  number of shares of  Common  Stock to be issued in such  conversion,  would
equal or exceed  twenty  percent  (20%) of the  shares  of  Common  Stock of the
Corporation  outstanding  on the  Closing  Date (the  "Threshold  Amount"),  the
Corporation  shall (i) issue to such holder the number of shares of Common Stock
otherwise  required to be issued to such  holder as a result of such  conversion
(including any shares of Common Stock  representing  cumulative  stock dividends
accrued to the applicable Conversion Date pursuant to Section 2) LESS the number
of shares of Common  Stock  otherwise  issuable to such holder  pursuant to such
conversion  in excess of the  Threshold  Amount (the  "Excess  Shares") and (ii)
shall  remit to such  holder,  in lieu of the Excess  Shares,  an amount of cash
equal to the number of Excess Shares  multiplied by the current market price per
share of Common Stock  (determined  as provided in Section 5)  determined  as of
such  Conversion  Date.  Upon such  issuance of Common Stock and payment of such
cash to the holder in lieu of the Excess Shares,  the Corporation's  obligations
to  such  holder  arising  as  a  result  of  such  conversion   (including  the
Corporation's   obligation  to  pay  cumulative  stock  dividends   through  the
applicable Conversion Date) shall be deemed fully satisfied.

         (e)  No  fractional  shares  of  Common  Stock  or  scrip  representing
fractional  shares  shall be issued  upon  conversion  of shares of the Series A
Preferred Stock pursuant to this Section 4. If more than one share of the Series
A Preferred  Stock shall be surrendered  for conversion by the same holder,  the
number of full shares of Common  Stock which shall be issuable  upon  conversion
thereof shall be computed on the basis of the aggregate  number of shares of the
Series A Preferred  Stock so

                                      -8-
<PAGE>

surrendered.  Instead  of any  fractional  shares of Common  Stock  which  would
otherwise be issuable  upon  conversion  of any shares of the Series A Preferred
Stock,  the Corporation  shall pay a cash adjustment in respect of such fraction
in an amount  equal to the same  fraction  of the  closing  bid price for Common
Stock  determined as of the last business day preceding the  Conversion  Date in
respect of such  shares.  The  closing  bid price for such day shall be the last
reported bid price on the  American  Stock  Exchange,  or if Common Stock is not
listed or  admitted  to  trading on such  exchange,  on the  principal  national
securities  exchange on which  Common Stock is listed or admitted to trading or,
if not listed or admitted to trading on any national  securities  exchange,  the
closing bid price of Common Stock on NASDAQ or any comparable  system. If Common
Stock is not quoted on NASDAQ or any comparable  system,  the Board of Directors
of the  Corporation  shall in good faith  determine the current  market price on
such basis as it considers appropriate.

         (f) When shares of Series A Preferred  Stock are  converted  (or deemed
converted) by a holder pursuant to this Section 4, the Corporation shall pay any
documentary,  stamp or similar  issue or transfer tax due on the issue of Common
Stock upon such conversion.

         (g) The Corporation shall reserve at all times out of the Corporation's
authorized but unissued shares of Common Stock a sufficient  number of shares of
Common  Stock to permit the  conversion  of the then  outstanding  shares of the
Series A Preferred  Stock  pursuant to this Section 4 and such  reserved  shares
shall not be used for any other purpose. All shares of Common Stock which may be
issued upon  conversion  of shares of the Series A Preferred  Stock  pursuant to
this Section 4 shall be validly issued,  fully paid and nonassessable.  In order
that  shares of Common  Stock may be  issued  upon  conversion  of shares of the
Series A Preferred  Stock,  the  Corporation  shall  comply with all  applicable
Federal and State  securities  laws and use its best efforts to list such shares
of Common  Stock to be issued upon  conversion  on each  securities  exchange on
which Common Stock is listed.

         (h) The conversion  rate (and the components  thereof) in effect at any
time for  conversion of Series A Preferred  Stock into Common Stock  pursuant to
this Section 4 shall be subject to adjustment from time to time as follows:

                  (i) In the event that the Corporation shall (1) pay a dividend
         in shares of  Common  Stock to  holders  of  Common  Stock,  (2) make a
         distribution in shares of Common Stock to holders of Common Stock,  (3)
         subdivide the outstanding  shares of Common Stock into a greater number
         of shares of Common Stock, (4) combine the outstanding shares of Common
         Stock into a smaller  number of shares of Common Stock or (5)

                                      -9-
<PAGE>
         otherwise  increase or  decrease  the number of  outstanding  shares of
         Common Stock through reclassification or any other event similar to the
         events  described in clauses (1) through (4) above, the conversion rate
         (and the  components  thereof)  in effect  pursuant  to this  Section 4
         immediately  prior to such  action  shall  be  adjusted  to the  extent
         required  to give  effect to the  impact of any such  event so that the
         holder  of any  shares  of the  Series  A  Preferred  Stock  thereafter
         surrendered for conversion pursuant to this Section 4 shall be entitled
         to  receive  the number of shares of Common  Stock  which he would have
         owned immediately following such action had such shares of the Series A
         Preferred  Stock  been  converted   immediately  prior  thereto.   Such
         adjustment  shall be made  whenever  any event listed above shall occur
         and shall become effective (A) immediately after the record date in the
         case of a dividend  or a  distribution  or other  applicable  event for
         which a record  date is used and (B)  immediately  after the  effective
         date in the case of a subdivision or  combination  or other  applicable
         event for which a record date is not used.

                  (ii) In case the Corporation  shall  distribute to all holders
         of the Common  Stock  shares of any class of capital  stock  other than
         Common  Stock,  evidences of  indebtedness  or other assets (other than
         non-extraordinary  cash dividends out of current or retained earnings),
         or shall distribute to substantially all holders of Common Stock rights
         or warrants to  subscribe  for  securities,  then in each such case the
         number of shares of the  Common  Stock  into  which  each  share of the
         Series A Preferred  Stock  shall be  converted  shall be adjusted  (and
         appropriate  adjustments  shall be made to the  component  parts of the
         applicable  conversion rate) so that such number shall equal the number
         determined  by  multiplying  the number of shares of Common  Stock into
         which  such  share of the  Series A  Preferred  Stock  was  convertible
         immediately  prior to the date of such  distribution  by a fraction  of
         which the numerator  shall be the current  market price of Common Stock
         (determined  as  provided  in Section 5) on the record  date  mentioned
         below, and of which the denominator  shall be such current market price
         of Common Stock, less the then fair market value (as determined in good
         faith by the Board of Directors of the Corporation, whose determination
         shall be conclusive  evidence of such fair market value) of the portion
         of the assets so distributed or of such subscription rights or warrants
         applicable to one share of Common Stock.  Such adjustment  shall become
         effective  immediately  after the record date for the  determination of
         the holders of Common Stock entitled to receive such distribution.

                  (iii) The Corporation  shall provide at least 10 business days
         advance notice to holders of Series A

                                      -10-
<PAGE>

         Preferred  Stock  of any  record  date or  other  applicable  date  for
         determining  shareholders  entitled to participate in any of the events
         described in this Section 4(h) or other similar events not described in
         this  Section  4(h) which would have a dilutive  effect on the Series A
         Preferred  Stock or the Common  Stock into which the Series A Preferred
         Stock is convertible.

         (i) No adjustment in the conversion rate (or its component parts) under
this  Section  4 shall be  required  until  cumulative  adjustments  result in a
concomitant  change of 1% or more of the  conversion  rate as in effect prior to
the  last  adjustment  of the  conversion  rate;  PROVIDED,  HOWEVER,  that  any
adjustments  which by reason of this  Section  4(i) 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. No adjustment to the
conversion rate shall be made for non-extraordinary cash dividends.

         (j) In the event that,  as a result of an  adjustment  made pursuant to
Section 4(h), the holder of any share of the Series A Preferred Stock thereafter
surrendered  for  conversion  shall  become  entitled  to receive  any shares of
capital stock of the Corporation  other than shares of Common Stock,  thereafter
the number of such other shares so receivable  upon  conversion of any shares of
the Series A 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 with
respect to the Common Stock contained in this Section 4.

         (k) The Corporation may make such increases in the conversion  rate, in
addition to those  required by Sections  4(h)(i) and (ii), as it considers to be
advisable in order that any event  treated for Federal  income tax purposes as a
dividend  of  stock or stock  rights  shall  not be  taxable  to the  recipients
thereof.

         (l)  Whenever  the  conversion  rate  (or any  components  thereof)  is
adjusted  pursuant to this Section 4, the Corporation shall promptly mail to all
holders  of record of shares  of the  Series A  Preferred  Stock a notice of the
adjustment  and shall  cause to be  prepared a  certificate  signed by the chief
financial officer of the Corporation or, if requested in writing by holders of a
majority  of the  shares of  Series A  Preferred  Stock  then  outstanding,  the
Corporation's  outside  accountants  or  a  reputable  investment  banking  firm
selected by the Corporation  setting forth the adjusted conversion rate (and the
component  parts  thereof)  and a brief  statement of the facts  requiring  such
adjustment and the  computation  thereof.  Such  certificate  shall forthwith be
filed with each transfer agent for the shares of the Series A Preferred Stock.

                                      -11-
<PAGE>
         (m) If any of the following shall occur:  (i) any  reclassification  or
change of outstanding  shares of Common Stock issuable upon conversion of shares
of the Series A Preferred  Stock (other than a change in par value,  or from par
value to no par value,  or from no par value to par  value,  or as a result of a
subdivision  or  combination),  (ii) any  consolidation  or  merger to which the
Corporation  is a party  other  than a merger  in which the  Corporation  is the
continuing  corporation and which does not result in any reclassification of, or
change (other than a change in name,  or par value,  or from par value to no par
value,  or from no par value to par value,  or as a result of a  subdivision  or
combination)  in,  outstanding  shares  of  Common  Stock or  (iii)  any sale or
conveyance  of all or  substantially  all of the  property  or  business  of the
Corporation  as  an  entirety,  then  the  Corporation,  or  such  successor  or
purchasing  corporation,  as the case may be, shall, as a condition precedent to
such  reclassification,  change,  consolidation,  merger,  sale  or  conveyance,
provide in its certificate of  incorporation or other charter document that each
share of the Series A Preferred Stock shall be convertible  under this Section 4
into the kind and amount of shares of  capital  stock and other  securities  and
property  (including  cash)  receivable  upon  such  reclassification,   change,
consolidation, merger, sale or conveyance by a holder of the number of shares of
Common Stock deliverable upon conversion of such share of the Series A Preferred
Stock immediately prior to such reclassification, change, consolidation, merger,
sale or conveyance.  Such certificate of incorporation or other charter document
shall provide for adjustments and protection which shall be as nearly equivalent
as may be practicable to the adjustments  provided for in this Section 4. If, in
the case of any such  consolidation,  merger,  sale or conveyance,  the stock or
other securities and property (including cash) receivable  thereupon by a holder
of  Common  Stock  includes  shares of  capital  stock or other  securities  and
property of a corporation other than the successor  purchasing  corporation,  as
the case may be, in such  consolidation,  merger,  sale or conveyance,  then the
certificate of incorporation or other charter document of such other corporation
shall contain such additional provisions to protect the interests of the holders
of shares of the  Series A  Preferred  Stock as the  Board of  Directors  of the
Corporation shall reasonably consider necessary by reason of the foregoing.  The
provision   of  this   Section  4(m)  shall   similarly   apply  to   successive
consolidations, mergers, sales or conveyances.

         (n) No sooner than fifteen (15)  business  days nor later than five (5)
business days prior to the consummation of a transaction  referred to in clauses
(ii) or (iii) of  Section  4(m) (a  "Major  Transaction"),  but not prior to the
public  announcement of such Major  Transaction,  the Corporation  shall deliver
written  notice (a "Notice  of Major  Transaction")  to each  holder of Series A
Preferred Stock,  which Notice of Major Transaction shall be deemed to have been
delivered to the holder one (1) business day

                                      -12-
<PAGE>


after the  Corporation's  sending of such notice (for  overnight  delivery) by a
common carrier,  if such delivery is to be made in the United States, or two (2)
business  days after the  Corporation's  sending of such notice (for two (2) day
delivery)  by common  carrier,  if such  notice is to be  delivered  outside the
United States.  Such Notice of Major  Transaction  shall indicate the amount and
type(s) of consideration (the "Major Transaction  Consideration") the holders of
Series A Preferred  Stock would  receive for their  shares of Series A Preferred
Stock in the related Major Transaction. Such holder may elect to redeem all or a
portion of such  holder's  shares of Series A  Preferred  Stock for an amount in
cash equal to $125 per share of Series A Preferred  Stock held by such holder to
be so  redeemed  in  lieu  of  the  Major  Transaction  Consideration  or  other
securities  and/or  property  that would  otherwise  be  payable to such  holder
pursuant to Section  4(m). A holder may  exercise  such  election by  delivering
written notice of such election to the Corporation,  together with  certificates
for the shares of Series A Preferred  Stock to be redeemed  in  connection  with
such  election,  within five (5) business  days of the  holder's  receipt of the
related Notice of Major Transaction,  which notice shall be deemed given one (1)
business   day  after  the  holder  sends  such  notice   (together   with  such
certificates) from the United States by common carrier for overnight delivery or
two (2)  business  days after the holder sends such notice  (together  with such
certificates)  from outside the United States by common  carrier for two (2) day
delivery.  In the event  that such Major  Transaction  is not  completed  within
fifteen (15) business  days after the  Corporation  is given a holder's  related
notice of election  pursuant to the prior sentence,  such election shall be null
and  void  and  the  Corporation   shall  promptly  return  the   certificate(s)
representing  the Series A  Preferred  Stock  delivered  by such  holder to such
holder; provided, that the Corporation will comply with the notice provisions of
this  Section  4(n)  with  respect  to any  later  consummation  of  such  Major
Transaction.  This  Section  4(n)  shall  not  apply  in  respect  of any  Major
Transaction that occurs after the second anniversary of the Closing Date.

                  (o) (i)  After  the  occurrence  of a Change  in  Control  (as
         defined below), other than in connection with a Major Transaction, each
         holder  of Series A  Preferred  Stock  shall  have the  right,  at such
         holder's option,  to require the Corporation to redeem all or a portion
         of such  holder's  Series A Preferred  Stock for an amount per share in
         cash  equal  to the  greater  of (A) $125  and (B) the  product  of the
         aggregate number of shares of Common Stock into which a share of Series
         A Preferred  Stock is  convertible  (assuming such  conversion  were to
         occur on the last day preceding  the  effective  date for the Change of
         Control)  multiplied  by the current  market  price per share of Common
         Stock  (determined  as  provided  in  Section  5) as of the  last  date
         preceding the effective date of such Change of Control. As used in this

                                      -13-
<PAGE>
         Section 4(o), a "Change in Control" shall be deemed to have occurred at
         such time as either Douglas R. Eger or Thomas M. Fitzgerald cease to be
         either a director or officer of the Corporation.  The rights of holders
         of Series A Preferred  Stock under this Section 4(o) shall not apply in
         respect  of  any  Change  of  Control   that  occurs  after  the  first
         anniversary of the Closing Date.

                  (ii) The  Corporation  shall  provide  each holder of Series A
         Preferred  Stock with written notice of the occurrence of any Change of
         Control (a "Change of Control  Notice")  within two (2)  business  days
         after the occurrence of such Change of Control. Each holder may require
         the  Corporation to redeem all or a portion of such holder's  shares of
         Series A Preferred  Stock  pursuant to this Section 4(o) by  delivering
         written  notice (a "Notice of  Redemption  at Option of Holder") to the
         Corporation  to such effect within ten (10) business days after receipt
         of the applicable Change of Control Notice,  which Notice of Redemption
         at  Option of Holder  shall be  deemed to have been  delivered  one (1)
         business day after such holder's sending, if such notice is sent within

         Section 5.  CALCULATIONS  OF CURRENT MARKET PRICE OF COMMON STOCK.  For
purposes of calculations  relating to the Series A Preferred Stock that refer to
the current market price per share of Common Stock, the current market price per
share of Common  Stock on or as of any day shall be deemed to be the  average of
the closing bid prices for the ten (10) consecutive trading days ending the last
trading day before the day in question. The closing bid price for each day shall
be the last  reported bid price on the  American  Stock  Exchange,  or if Common
Stock is not listed or admitted to trading on such  exchange,  on the  principal
national  securities  exchange  on which  Common  Stock is listed or admitted to
trading  or, if not listed or  admitted  to trading on any  national  securities
exchange,  the  closing  bid price of Common  Stock on NASDAQ or any  comparable
system, or if Common Stock is not quoted on NASDAQ or any comparable system, the
closing bid price as furnished by any two members of the National Association of
Securities Dealers,  Inc. selected from time to time by the Corporation for that
purpose.  If Common Stock is not so quoted on NASDAQ or any  comparable  system,
the Board of Directors of the  Corporation  shall  reasonably  and in good faith
determine  the current  market price on such basis as it considers  appropriate.
For  example,  in the event that the  current  market  price per share of Common
Stock is to be determined as of a Conversion  Date, the current market price per
share of Common Stock shall equal the average of the last  reported bid price as
reported by the American  Stock  Exchange for the ten (10)  consecutive  trading
days ending the last trading day before such  Conversion Date (assuming that the
Common Stock is listed and admitted for trading on the American  Stock  Exchange
and a  reported  bid price for  Common  Stock is  placed on the  American  Stock
Exchange on each such trading day).

         Section 6. LIMITATIONS. (a) In addition to any other rights provided by
applicable  law,  so long as any  shares  of the  Series A  Preferred  Stock are
outstanding,  the Corporation  shall not,  without the affirmative  vote, or the
written consent as provided by law, of the holders of at least  two-thirds (2/3)
of the outstanding shares of the Series A Preferred Stock,  voting as a separate
class,

                  (i) create,  authorize or issue any class or series of capital
         stock,  or  rights  to  subscribe  to  or  acquire,   or  any  security
         convertible  into,  any class or series of capital  stock ranking as to
         payment of dividends, distribution of assets upon liquidation or voting
         rights, prior to the Series A Preferred Stock; or

                  (ii) amend, alter or appeal, whether by merger,  consolidation
         or otherwise, any of the provisions of the Certificate of Incorporation
         (including this Certificate of Designation) that would change the

                                      -15-
<PAGE>
         preferences,  rights or powers  with  respect to the Series A Preferred
         Stock so as to affect the Series A Preferred Stock adversely.

         (b) In addition to any other rights provided by applicable law, so long
as any shares of the Series A Preferred Stock are  outstanding,  the Corporation
shall not,  without the affirmative  vote, or the written consent as provided by
law, of the holders of at least  two-thirds  (2/3) of the outstanding  shares of
the Series A  Preferred  Stock,  voting as a separate  class,  issue or agree to
issue any Common Stock or any security  convertible  or otherwise  exchangeable,
directly or  indirectly,  for Common Stock if such shares of Common Stock are to
be issued,  or such  convertible  securities are to be converted to or exchanged
for shares of Common  Stock,  at a price per share less than the current  market
price for the Common Stock  (determined  as provided in Section 5) as of the day
immediately  preceding  the date of the  issuance of such  Common  Stock or such
convertible or exchangeable  security (as the case may be);  provided,  however,
that the restrictions contained in this paragraph (b) shall not apply (i) to the
issuance of any such convertible or exchangeable securities that are convertible
or  exchangeable  at a fixed price (and not a floating price) per share equal to
or greater than the current  market price for the Common  Stock  (determined  as
provided  in  Section  5) as of the  date of  issuance  of such  convertible  or
exchangeable security, (ii) to the issuance of Common Stock and other securities
of the Corporation issuable upon the exercise or conversion of options, warrants
on other rights to purchase securities of the Corporation  outstanding as of the
date hereof,  (iii) to the issuance of any securities to officers,  directors or
employees of the Corporation or any of its subsidiaries, (iv) to the issuance of
any securities of the Corporation in an  underwritten  public offering or (v) to
any other  issuance  of  securities  after  the date  that is 90 days  after the
Closing  Date if the holders of Series A Preferred  Stock are first  delivered a
written notice (a "Right of First Refusal Notice") from the Corporation offering
such  holders on a PRO RATA basis the right to purchase  all or a portion of the
related  securities  at the same price  (and on the same  terms and  conditions,
offered to other  proposed  investors  (which notice shall set forth such price,
terms and  conditions).  In the event that the  Corporation  delivers a Right of
First Refusal Notice to any holder of Series A Preferred  Stock,  the failure by
such holder to commit in writing to purchase  such  holder's pro rata portion of
the securities  identified in such Right of First Refusal Notice within five (5)
business days of delivery thereof may be deemed by the Corporation to constitute
such  holder's  determination  not  to  so  purchase  such  securities  and  the
Corporation  shall then be permitted to sell such  securities to other investors
at the  price  and on the terms and  conditions  set forth in such  notice.  The
rights of holders of Series A  Preferred  Stock under this  paragraph  (b) shall
terminate on the first anniversary of the Closing Date.

         (c)  Notwithstanding  the  foregoing,  except as otherwise  required by
applicable law,  nothing herein contained shall require a vote or consent of the
holders of Series A Preferred Stock in connection with any increase in the total
number of authorized  shares of Common Stock.  The holders of Series A Preferred
Stock shall not be entitled to vote on any matter except (i) as provided in this
Section 6 and (ii) as required by law.

         Section  7.  LOST OR  STOLEN  CERTIFICATES.  Upon  (i)  receipt  by the
Corporation  from a holder of evidence  satisfactory  to the  Corporation of the
loss, theft,  destruction of any certificate(s)  representing shares of Series A
Preferred  Stock  and of an  indemnification  undertaking  by the  holder to the
Corporation  that is reasonably  satisfactory  to the  Corporation  or (ii) upon
surrender and  cancellation of  certificate(s)  representing  shares of Series A
Preferred  Stock that have been  mutilated,  the  Corporation  shall execute and
deliver  to such  holder  new  certificate(s)  representing  shares  of Series A
Preferred Stock of like tenor and date.  However,  the Corporation  shall not be
obligated to re-issue such lost, stolen,  destroyed or mutilated  certificate(s)
representing shares of Series A Preferred Stock if such holder contemporaneously
requests the Corporation to convert such shares of Series A Preferred Stock into
shares of Common  Stock or  otherwise  redeem such shares  pursuant to the terms
hereof.

Section 11 of the Plan,  the  maximum  aggregate  number of shares  which may be
optioned  and sold under the Plan is One  Million  (1,000,000)  Shares of Common
Stock. The Shares may be authorized,  but unissued,  or previously issued Shares
acquired by the Company and held in treasury.

                  If an Option  should  expire or become  unexercisable  for any
reason without having been exercised in full, the unpurchased  Shares covered by
such Option shall, unless the Plan shall have been terminated,  be available for
future grants of Options.

         4. ADMINISTRATION OF THE PLAN.

            (a) PROCEDURE.

                (i) The Plan shall be  administered  by the Board in  accordance
            with Rule 16b-3 under the  Exchange  Act ("Rule  16b-3");  provided,
            however,  that the Board may appoint a Committee to  administer  the
            Plan at any time or from time to time, and, provided  further,  that
            if the  Board is not  "disinterested"  within  the  meaning  of Rule
            16b-3,  the Plan shall be  administered by a Committee in accordance
            with Rule 16b-3.

                (ii) Once appointed, the Committee shall continue to serve until
            otherwise  directed  by the  Board.  From time to time the Board may
            increase the size of the  Committee and appoint  additional  members
            thereof, remove members (with or without cause), appoint new members
            in  substitution   therefor,  and  fill  vacancies  however  caused:
            provided,  however,  that at no time  may any  person  serve  on the
            Committee if that person's  membership would cause the Committee not
            to satisfy the "disinterested  administration"  requirements of Rule
            16b-3.

            (b) POWERS OF THE BOARD.  Subject to the provisions of the Plan, the
            Board  shall have the  authority,  in its  discretion:  (i) to grant
            Incentive  Stock Options and  Nonstatutory  Stock  Options;  (ii) to
            determine,  upon review of relevant  information  and in  accordance
            with Section 2 of the Plan, the Fair Market Value of the

                                       -3-

<PAGE>
            Common  Stock;  (iii) to determine  the exercise  price per Share of
            Options to be granted,  which  exercise price shall be determined in
            accordance  with  Section 8(a) of the Plan;  (iv) to  determine  the
            Employees to whom, and the time or times at which,  Options shall be
            granted and the number of Shares to be  represented  by each Option;
            (v) to  interpret  the Plan;  (vi) to  prescribe,  amend and rescind
            rules and regulations  relating to the Plan;  (vii) to determine the
            terms and  provisions  of each  Option  granted  (which  need not be
            identical) and, with the consent of the Optionee thereof,  modify or
            amend each Option;  (viii) to  accelerate or defer (with the consent
            of the Optionee) the exercise date of any Option;  (ix) to authorize
            any  person  to  execute  on behalf of the  Company  any  instrument
            required to effectuate the grant of an Option previously  granted by
            the Board;  (x) to accept or reject the election made by an Optionee
            pursuant  to  Section  17 of the  Plan;  and (xi) to make all  other
            determinations  deemed necessary or advisable for the administration
            of the Plan.

            (c) EFFECT OF BOARD'S DECISION.  All decisions,  determinations  and
            interpretations  of the  Board  shall be final  and  binding  on all
            Optionees  and any other  holders of any Options  granted  under the
            Plan.

         5. ELIGIBILITY.

            (a) Consistent with the Plan's purposes, Options may be granted only
to Employees of the Company as determined by the Board. An Employee who has been
granted an Option may, if he is  otherwise  eligible,  be granted an  additional
Option  or  Options.  Incentive  Stock  Options  may be  granted  only to  those
Employees who meet the requirements applicable under Section 422 of the Code.

            (b) All Options  granted to Employees of the Company  under the Plan
will be  subject  to  forfeiture  until  such  time  as the  Optionee  has  been
continuously employed by the Company for one year after the date of the grant of
the Options,  and may not be exercised  prior to such time.  At such time as the
Optionee  has been  continuously  employed  by the  Company  for one  year,  the
foregoing  restriction  shall lapse and the Optionee may exercise the Options at
any time otherwise consistent with the Plan.

            (c) With respect to Incentive  Stock  Options,  the  aggregate  Fair
Market Value  (determined at the time the Incentive  Stock Option is granted) of
the Common Stock with respect to which  Incentive  Stock Options are exercisable
for the first time by the employee  during any calendar year (under all employee
benefit  plans of the  Company)  shall not exceed One Hundred  Thousand  Dollars
($100,000).

                                       -4-
<PAGE>
         6. STOCKHOLDER  APPROVAL AND EFFECTIVE DATES. The Plan became effective
upon approval by the Board. No Option may be granted under the Plan after August
30, 2003 (ten years from the effective date of the Plan); provided, however that
the Plan and all  outstanding  Options shall remain in effect until such Options
have expired or until such Options are canceled.

         7. TERM OF  OPTION.  Unless  otherwise  provided  in the  Stock  Option
Agreement,  the term of each  Option  shall be five (5)  years  from the date of
grant  thereof.  In no case shall the term of any  Option  exceed ten (10) years
from the date of grant  thereof.  Notwithstanding  the above,  in the case of an
Incentive  Stock Option  granted to an Employee  who, at the time the  Incentive
Stock Option is granted,  owns ten percent  (10%) or more of the Common Stock as
such amount is  calculated  under  Section  422(b)(6) of the Code ("Ten  Percent
Stockholder"),  the term of the  Incentive  Stock Option shall be five (5) years
from the date of grant  thereof or such  shorter  time as may be provided in the
Stock Option Agreement.


         8. EXERCISE PRICE AND PAYMENT.

                  (a)  EXERCISE  PRICE.  The per  Share  exercise  price for the
            Shares to be  issued  pursuant  to  exercise  of an Option  shall be
            determined  by the  Board,  but in the  case of an  Incentive  Stock
            Option shall be no less than one hundred  percent (100%) of the Fair
            Market  Value per  share on the date of grant,  and in the case of a
            Nonstatutory Stock Option shall be no less than eighty-five  percent
            (85%) of the  Fair  Market  Value  per  share on the date of  grant.
            Notwithstanding  the  foregoing,  in the case of an Incentive  Stock
            Option  granted to an Employee who, at the time of the grant of such
            Incentive Stock Option, is a Ten Percent Stockholder,  the per Share
            exercise  price shall be no less than one hundred ten percent (110%)
            of the Fair Market Value per Share on the date of grant.

                  (b)  PAYMENT.  The  price  of  an  exercised  Option  and  the
            Employee's  portion of any taxes  attributable  to the  delivery  of
            Common Stock under the Plan, or portion thereof, shall be paid:

                       (i) In United  States  dollars in cash or by check,  bank
                  draft or money order payable to the order of the Company; or

                       (ii) At the discretion of the Board, through the delivery
                  of shares of Common Stock with an aggregate  Fair Market Value
                  equal to the option price and withholding taxes, if any; or

                                       -5-

<PAGE>
                       (iii) At the election of the Optionee pursuant to Section
                  17 and with the  consent  of the  Board  pursuant  to  Section
                  4(b)(x),  by the Company's  retention of such number of shares
                  of Common Stock subject to the exercised  Option which have an
                  aggregate  Fair Market Value on the exercise date equal to the
                  Employee's portion of the Company's aggregate federal,  state,
                  local  and   foreign  tax   withholding   and  FICA  and  FUTA
                  obligations  with respect to income  generated by the exercise
                  of the Option by Optionee;

                       (iv) By a combination of (i), (ii) and (iii) above; or

                       (v) In the manner provided in subsection (c) below.

                  The Board shall  determine  acceptable  methods for  tendering
Common  Stock  as  payment  upon  exercise  of an  Option  and may  impose  such
limitations and prohibitions on the use of Common Stock to exercise an Option as
it deems appropriate.

                  (c) FINANCIAL  ASSISTANCE  TO OPTIONEES.  The Board may assist
         Optionees in paying the exercise  price of Options  granted  under this
         Plan in the following manner:

                           (i) The  extension  of a loan to the  Optionee by the
                  Company; or

                           (ii) Payment by the Optionee of the exercise price in
                  installments; or

                           (iii) A guaranty by the Company of a loan obtained by
                  the Optionee from a third party.

                  The terms of any loans,  installment  payments or  guarantees,
including the interest rate and terms of repayment, and collateral requirements,
if any,  shall be determined by the Board,  in its sole  discretion.  Subject to
applicable margin  requirements,  any loans,  installment payments or guarantees
authorized by the Board  pursuant to the Plan may be granted  without  security,
but the maximum  credit  available  shall not exceed the exercise  price for the
Shares  for which the  Option is to be  exercised,  plus any  federal  and state
income tax liability incurred in connection with the exercise of the Option.

         9. EXERCISE OF OPTION.

            (a)  PROCEDURE  FOR EXERCISE;  RIGHTS AS A  STOCKHOLDER.  Any Option
granted  hereunder  shall be exercisable at such times and under such conditions
as determined by the Board,  including  performance criteria with respect to the
Company and/or the

                                       -6-
<PAGE>
Optionee,  and as shall be  permissible  under  the  terms of the  Plan.  Unless
otherwise  determined  by the  Board  at the time of  grant,  an  Option  may be
exercised in whole or in part.  An Option may not be exercised for a fraction of
a Share.

            An Option  shall be deemed to be exercised  when  written  notice of
such exercise has been given to the Company in accordance  with the terms of the
Option by the person  entitled to exercise  the Option and full  payment for the
Shares with  respect to which the Option is exercised  has been  received by the
company.  Full  payment  may,  as  authorized  by  the  Board,  consist  of  any
consideration  and method of payment  allowable  under Section 8(b) of the Plan.
Until the issuance (as  evidenced by the  appropriate  entry on the books of the
Company or of a duly  authorized  transfer  agent of the  Company)  of the stock
certificate evidencing such Shares, no right to vote or receive dividends or any
other rights as a  stockholder  shall exist with respect to the Optioned  Stock,
notwithstanding  the exercise of the Option.  No  adjustment  will be made for a
dividend or other right for which the record date is prior to the date the stock
certificate is issued, except as provided in Section 11 of the Plan.

            Exercise  of an Option in any manner  shall  result in a decrease in
the number of Shares which thereafter may be available, both for purposes of the
Plan and for sale under the Option,  by the number of Shares to which the Option
is exercised.

            (b)  TERMINATION  OF  STATUS  AS  AN  EMPLOYEE.   If  an  Employee's
employment by the Company is terminated  for cause,  then any Option held by the
Employee  shall be immediately  canceled upon  termination of employment and the
Employee  shall have no further  rights  with  respect  to such  Option.  Unless
otherwise  provided  in the Stock  Option  Agreement  (which  may reduce but not
increase the time period described  below),  if an Employee's  employment by the
Company is terminated  for reasons  other than cause,  and does not occur due to
death or disability,  then the Employee may, with the consent of the Board,  but
only  within  ninety (90) days after the date he ceases to be an Employee of the
Company,  exercise  his Option to the extent that he was entitled to exercise it
at the date of such  termination.  To the  extent  that he was not  entitled  to
exercise the Option at the date of such termination,  or if he does not exercise
such  Option  (which he was  entitled  to  exercise)  within the time  specified
herein, the Option shall terminate.

            (c)  DISABILITY.  Unless  otherwise  provided  in the  Stock  Option
Agreement (which may reduce but not increase the time period  described  below),
notwithstanding  the provisions of Section 9(b) above,  in the event an Employee
is  unable  to  continue  his  employment  with the  Company  as a result of his
permanent and total disability (as defined in Section 22(e)(3) of

                                       -7-

<PAGE>
the  Code),  he may,  but  only  within  twelve  (12)  months  from  the date of
termination, exercise his Option to the extent he was entitled to exercise it at
the date of such termination. To the extent that he was not entitled to exercise
the Option at the date of  termination,  or if he does not exercise  such Option
(which he was entitled to exercise) within the time specified herein, the Option
shall terminate.

            (d) DEATH.  Unless otherwise  provided in the Stock Option Agreement
(which may reduce but not  increase  the time  period  described  below),  if an
Employee  dies  during the term of the Option and is at the time of his death an
Employee of the Company who shall have been in continuous  status as an Employee
since the date of grant of the Option,  the Option may be  exercised at any time
within  twelve (12) months  following the date of death (or such other period of
time as is determined by the Board) by the Employee's  estate or by a person who
acquired the right to exercise the Option by bequest or inheritance, but only to
the extent that an Employee  was  entitled to exercise the Option on the date of
death. To the extent the Employee was not entitled to exercise the Option on the
date of death, or if the Employee's  estate, or person who acquired the right to
exercise the Option by bequest or  inheritance,  does not  exercise  such Option
(which he was entitled to exercise) within the time specified herein, the Option
shall terminate.

         10. NON-TRANSFERABILITY OF OPTIONS. An Option may not be sold, pledged,
assigned,  hypothecated,  transferred or disposed of in any manner other than by
will or by the laws of descent or  distribution,  or  pursuant  to a  "qualified
domestic relations order" under the Code and ERISA, and may be exercised, during
the lifetime of the Optionee, only by the Optionee.

         11.  ADJUSTMENTS UPON CHANGES IN CAPITALIZATION  OR MERGER.  Subject to
any required action by the stockholders of the Company,  the number of shares of
Common Stock  covered by each  outstanding  Option,  and the number of shares of
Common Stock which have been  authorized  for issuance  under the Plan but as to
which no Options have yet been  granted or which have been  returned to the Plan
upon  cancellation or expiration of an Option, as well as the price per share of
Common Stock covered by each such outstanding  Option,  shall be proportionately
adjusted for any  increase or decrease in the number of issued  shares of Common
Stock  resulting  from a stock  split,  reverse  stock  split,  stock  dividend,
combination or  reclassification  of the Common Stock,  or any other increase or
decrease in the number of issued shares of Common Stock effected without receipt
of  consideration  by the Company;  provided,  however,  that  conversion of any
convertible securities of the Company shall not be deemed to have been "effected
without receipt of  consideration."  Such adjustment shall be made by the Board,
whose  determination  in that respect  shall be final,  binding and  conclusive.
Except as expressly

                                       -8-

<PAGE>
provided herein,  no issuance by the company of shares of stock of any class, or
securities  convertible  into shares of stock of any class,  shall affect and no
adjustment by reason thereof,  shall be made with respect to the number or price
of shares of Common Stock subject to an Option.

                  In the event of the proposed dissolution or liquidation of the
Company, the Option will terminate immediately prior to the consummation of such
proposed action,  unless otherwise  provided by the Board. The Board may, in the
exercise of its sole discretion in such instances, declare that any Option shall
terminate  as of a date fixed by the Board and give each  Optionee  the right to
exercise  his  Option  as to all or any part of the  Optioned  Stock,  including
Shares as to which the Option would not otherwise be  exercisable.  In the event
of a proposed sale of all or substantially all of the assets of the Company,  or
the merger of the Company with or into another corporation,  the Option shall be
assumed  or  an  equivalent  option  shall  be  substituted  by  such  successor
corporation or a parent or subsidiary of such successor corporation,  unless the
Board  determines,  in the exercise of its sole  discretion  and in lieu of such
assumption or  substitution,  that the Optionee shall have the right to exercise
the option as to all of the  Optioned  Stock,  including  Shares as to which the
Option would not  otherwise be  exercisable.  If the Board makes an Option fully
exercisable  in lieu of  assumption  or  substitution  in the  event of a merger
of`sale of assets,  the Board shall notify the Optionee that the Option shall be
fully  exercisable  for a period of sixty (60) days from the date of such notice
(but not later than the  expiration  of the term of the Option  under the Option
Agreement), and the Option will terminate upon the expiration of such period.

         12. TIME OF GRANTING OPTIONS. The date of grant of an Option shall, for
all purposes,  be the date on which the Board makes the  determination  granting
such Option. Notice of the determination shall be given to each Employee to whom
an Option is so granted within a reasonable time after the date of such grant.

         13. AMENDMENT AND TERMINATION OF THE PLAN.

                  (a)  AMENDMENT  AND  TERMINATION.   The  Board  may  amend  or
         terminate  the Plan from time to time in such respects as the Board may
         deem  advisable;  provided,  however,  that the following  revisions or
         amendments  shall require  approval of the Stockholders of the Company,
         to the extent required by law, rule or regulation:

                       (i) Any material increase in the number of Shares subject
                  to the Plan, other than in connection with an adjustment under
                  Section 11 of the Plan;

                                       -9-

<PAGE>
                       (ii)  Any  material  change  in  the  designation  of the
                  Employees eligible to be granted Options; or

                       (iii) Any material  increase in the benefits  accruing to
                  participants under the Plan.

             (b) EFFECT OF  AMENDMENT  OR  TERMINATION.  Any such  amendment  or
         termination  of the Plan shall not affect Options  already  granted and
         such Options  shall remain in full force and effect as if this Plan had
         not been  amended  or  terminated,  unless  mutually  agreed  otherwise
         between the Optionee and the Board,  which agreement must be in writing
         and signed by the Optionee and the Company.

         14.  CONDITIONS  UPON  ISSUANCE OF SHARES.  Shares  shall not be issued
pursuant to the exercise of an Option unless the exercise of such Option and the
issuance  and  delivery of such Shares  pursuant  thereto  shall comply with all
relevant provisions of law, including, without limitation, the Securities Act of
1933,  as amended,  the  Exchange  Act,  the rules and  regulations  promulgated
thereunder, and the requirements of any stock exchange upon which the Shares may
then be listed,  and shall be further subject to the approval of counsel for the
Company with respect to such compliance.

                  As a condition to the  exercise of an Option,  the Company may
require the person  exercising  such Option to represent and warrant at the time
of any such exercise that the Shares are being purchased only for investment and
without  any  present  intention  to sell or  distribute  such Shares if, in the
opinion of counsel for the company,  such a representation is required by any of
the aforementioned relevant provisions of law.

                  Inability  of  the  Company  to  obtain   authority  from  any
regulatory body having jurisdiction,  which authority is deemed by the Company's
counsel to be necessary to the lawful issuance and sale of any Shares hereunder,
shall relieve the Company of any liability in respect of the failure to issue or
sell  such  Shares  as to which  such  requisite  authority  shall not have been
obtained.

                  In the case of an  Incentive  Stock  Option,  any Optionee who
disposes of Shares of Common  Stock  acquired  upon the exercise of an Option by
sale or exchange (a) either  within two (2) years after the date of the grant of
the Option  under which the Common Stock was acquired or (b) within one (1) year
after the acquisition of such Shares of Common Stock shall notify the Company of
such disposition and of the amount realized upon such disposition.

                                      -10-

<PAGE>
         15.  RESERVATION  OF SHARES.  The Company will at all times reserve and
keep  available  such  number of Shares as shall be  sufficient  to satisfy  the
requirements of the Plan.

         16.  OPTION  AGREEMENT.  Options  shall be  evidenced  by Stock  Option
Agreements in such form as the Board shall approve.

         17. WITHHOLDING TAXES. Subject to Section 4(b)(x) of the Plan and prior
to the Tax Date,  the  Optionee  may make an  irrevocable  election  to have the
Company  withhold  from those Shares that would  otherwise be received  upon the

         6.2 RESTRICTION ON EXERCISE.  Options shall be exercisable at such time
or times and subject to such terms and  conditions as shall be determined by the
Board at grant;  PROVIDED,  HOWEVER, that in the case of the Eligible Director's

exercisable, unless a longer vesting period is otherwise determined by the Board

whole or in part based on performance and/or such other factors as the Board may
determine in its sole  discretion;  PROVIDED,  HOWEVER,  that no Option shall be

and agrees,  for the Eligible Director and his permitted  transferees  hereunder

                                 WITHHOLDING TAX

         The Company may, in its discretion, require an Eligible Director to pay
to the Company,  at the time of exercise of an Option an amount that the Company
deems necessary to satisfy its obligations to withhold  federal,  state or local
income or other taxes (which for  purposes of this Article  includes an Eligible
Director's  FICA  obligation)  incurred  by  reason of such  exercise.  When the
exercise of an Option does not give rise to the  obligation to withhold  federal
income  taxes on the date of  exercise,  the  Company  may,  in its  discretion,
require an  Eligible  Director  to place  Shares  purchased  under the Option in
escrow for the  benefit  of the  Company  until such time as federal  income tax
withholding  is required on amounts  included in the Eligible  Director's  gross
income as a result of the exercise of an Option.  At such time, the Company,  in
its discretion, may require an Eligible Director to pay to the Company an amount
that the Company deems necessary to satisfy its obligation to withhold  federal,
state or local taxes incurred by reason of the exercise of the Option,  in which
case the Shares  will be released  from escrow upon such  payment by an Eligible
Director.

decreased,  changed into or exchanged into a different  number or kind of Shares
or  securities  of  the  Company   through   reorganization,   recapitalization,
reclassification,  stock  dividend,  stock split,  reverse  stock split or other
similar transaction,  an appropriate and proportionate  adjustment shall be made
to the  maximum  number  and kind of Shares as to which  Options  may be granted
under the Plan. A corresponding adjustment changing the number or kind of Shares
allocated  to  unexercised  Options or portions  thereof,  which shall have been
granted prior to any such change, shall likewise be made. Any such adjustment in
the  outstanding  Options  shall be made without  change in the  Purchase  Price
applicable  to the  unexercised  portion  of  the  Option  with a  corresponding
adjustment  in  the  Exercise  Price  of  the  Shares  covered  by  the  Option.
Notwithstanding the foregoing,  there shall be no adjustment for the issuance of
Shares on conversion of notes, preferred stock or exercise of warrants or Shares
issued by the Board for such consideration as the Board deems appropriate.

         9.2 DISSOLUTION OR LIQUIDATION.  Upon the dissolution or liquidation of
the Company,  or upon a  reorganization,  merger or consolidation of the Company
with one or more  corporations  as a  result  of which  the  Company  is not the
surviving  corporation,  or upon a sale of substantially  all of the property or
more  than  80%  of the  then  outstanding  Shares  of the  Company  to  another
corporation,  the Company  shall give to each  Eligible  Director at the time of
adoption of the plan for liquidation,  dissolution,  merger or sale either (1) a
reasonable  time  thereafter  within  which to exercise  the Option prior to the
effective date of such liquidation or

                                       -6-

The Board of Directors
Sheffield Medical Technologies Inc.:


We consent to incorporation by reference in the Registration Statement (Form S-3
No.  33-95732,  Form S-8 No. 33-95262 and Form S- 8  No.333-14867)  of Sheffield

Our report dated  February  11, 1994,  contains an  explanatory  paragraph  that
states  that the  Company's  recurring  losses and net  deficit  position  raise
substantial  doubt  about  its  ability  to  continue  as a going  concern.  The
consolidated  financial  statements  do not include any  adjustments  that might
result from the outcome of this uncertainty.
