                                     PART I

ITEM 1. BUSINESS

INTRODUCTION

    DynaGen,  Inc. ("DynaGen" or the "Company") develops and markets proprietary
and generic therapeutic and diagnostic products for the human healthcare market.
During 1996, DynaGen began expanding its business focus from being a development
and licensing  company to building a diversified  healthcare  company focused on
the  manufacture  and  distribution  of  generic  drug  products  and  specialty
pharmaceuticals,  as  well  as the  continued  development  of  therapeutic  and
diagnostic products.  The Company intends to implement this strategy through the
acquisition of businesses,  technologies  and products that the Company believes
are undervalued,  as well as through continued internal product development.  In
August 1996, the Company acquired the tablet business of Able Laboratories, Inc.
("Able"), a generic pharmaceutical product subsidiary of Alpharma, Inc.

    Prior to the Able acquisition,  DynaGen's  business  consisted of developing
proprietary  diagnostic  products and  proprietary  therapeutic  and  diagnostic
product   candidates.   The  Company's  lead  therapeutic   product   candidate,
NicErase(r)-SL, is intended as an aid in smoking cessation and to provide relief
from  nicotine  withdrawal  symptoms.  The  Company is  currently  conducting  a
multi-center  pivotal Phase 3 clinical trial of  NicErase-SL.  Results from this
trial are  anticipated to be available in the second quarter of 1997.  There can
be no assurance that the results of the Company's ongoing Phase 3 clinical trial
of NicErase-SL  will be favorable for the Company.  In addition,  the Company is
also considering  alternative  delivery formats for its lobeline-based  NicErase
technology and intends to seek strategic  partners to further develop and market
these  delivery  formats.  In December 1996,  the  Company  licensed  worldwide,
exclusive  rights to  develop a lobeline  sulfate  nasal  delivery  formulation,
NicErase-NS, to Nastech Pharmaceutical Company, Inc. ("Nastech").

    DynaGen is also developing  OrthoDyn(r),  a bioresorbable bone cement system
for bone and joint  repair which is  currently  in the  preclinical  development
stage. In April 1997, the Company entered into an agreement with Smith & Nephew,
plc ("Smith & Nephew") providing Smith & Nephew an exclusive period of 12 months
to evaluate the OrthoDyn product's human orthopaedic applications. Additionally,
the Company expanded its resorbable  polymer technology patent base by obtaining
a patent for its Sleeper(tm)  vaccine  technology  which enables  vaccines to be
delivered in a single administration rather than in multiple vaccinations over a
period of time.

    In  December  1996,  the  Company  obtained  United  States  Food  and  Drug
Administration  (the "FDA")  clearance to market its  proprietary  NicCheck(r) I
product for detection of nicotine  and/or its  metabolites in urine as an aid in
indicating  smoking status of  individuals.  The Company has recently  commenced
marketing  NicCheck  to  physicians,   smoking  cessation  programs,  HMOs,  and
insurance companies.

    In  December  1996,  the  Company  licensed  technology  from  BioLoc,  Inc.
("BioLoc") that is intended to improve the accuracy and  efficiency,  and reduce
the overall cost of,  breast  surgical  biopsy  procedures.  The Company is also
conducting  early stage  research  on a  proprietary  bacterial  extract for the
treatment of infectious diseases.

    The Company  changed its year end from June 30 to December 31.  Accordingly,
the Company  began a new 12 month fiscal year on January 1, 1997.  The six month
period  resulting from this change,  July 1, 1996 through  December 31, 1996, is
referred to as the "Transition Period."

 MULTISOURCE BUSINESS

    The U.S.  multisource  or  generic  pharmaceutical  market  approximates  $8
billion  in annual  sales.  This  sector  has  grown due to a number of  factors
including  the large number of drugs coming off patent,  the growing  importance
and impact of managed care  organizations  which  prefer lower cost  generics to
brand products, and the increasing physician, pharmacist and consumer acceptance
of generic drugs. Generic drugs are the chemical and therapeutic  equivalents of
brand-name drugs.  They are required to meet the same governmental  standards as
the  brand-name  drugs and must receive FDA approval  prior to  manufacture  and
sale.  Generic drugs may be manufactured  and marketed only if relevant  patents
(and  any  additional   government-mandated  market  exclusivity  periods)  have
expired.  These drugs are typically  sold under their generic  chemical names at
prices significantly below those of their brand-name equivalents.


                                       1


    To successfully participate in the multisource business,  DynaGen intends to
compete  with  other  generic  companies  through  vertical  integration  of key
elements of the  multisource  business  including  manufacturing,  packaging and
distribution.  In August 1996,  the Company  acquired Able, a 46,000 square foot
tablet and suppository manufacturing facility. As part of this acquisition,  the
Company  obtained  rights to eleven approved  Abbreviated New Drug  Applications
("ANDAs") as well as other generic formulations.  Since the acquisition, DynaGen
has updated and expanded the manufacturing capability,  validated several of the
acquired products,  retrained employees in quality assurance procedures, and has
successfully met FDA requirements and guidelines to manufacture  these products.
The Company is  increasing  sales of its current  generic  products  through the
expansion of its distribution  networks and by providing contract  manufacturing
services to various pharmaceutical companies. The following is a list of generic
products that the Company obtained in the Able acquisition:

    In April 1997, the Company signed an agreement with Kali  Laboratories  Inc.
("Kali"),  a privately-held  company  specializing in the development of generic
drugs.  The agreement  provides for Kali to assist  DynaGen in developing  seven
specific  generic drugs and obtaining FDA approval for these drugs.  The patents
on these targeted drugs have expired or will expire over the next five years and
provide an  opportunity  for DynaGen to introduce  generic  equivalents.  Kali's
management and its scientific  staff have  significant  experience in developing
and obtaining  approvals on generic drugs.  DynaGen believes that by outsourcing
the development and approval activities it will benefit from the experience of a
highly  seasoned  team of scientists  while  reducing the  requirement  of major
investment in personnel and laboratory equipment.

    To complement the acquisition of Able and pursue vertical  integration,  the
Company  recently  entered into an  agreement to acquire all of the  outstanding
shares  of  Superior  Pharmaceutical  Company  ("Superior"),   a  privately-held
distributor  of  generic  pharmaceutical  products.  Superior  has  its  primary
operations in Cincinnati,  Ohio, where it employs  approximately 65 people,  and
has 40,000 square feet of office,  warehouse and  distribution  space.  Superior
reported 1996 sales of approximately  $32 million with pre-tax income of over $3
million.  Under  the  terms  of  the  agreement,  DynaGen  will  pay  Superior's
shareholders a total of $16.5 million,  consisting of cash, three-year notes and
shares of DynaGen Common Stock.  The  shareholders may also receive certain cash
incentive  payments  based on  Superior's  performance  during  the three  years
following the close of the transaction. The aquisition of Superior is subject to
customary  closing  conditions and the Company intends to close this acquisition
during the second  quarter of 1997.  There can be no assurance that the Superior
aquisition will close in the second quarter of 1997, or at all.


                                       2



    The  Company  plans  to raise  capital  in order  to  finance  the  proposed
acquisition  of  Superior  through the sale of its  securities.  There can be no
assurance  that the Company  will be able to secure this  financing or that such
financing  will be  available on  favorable  terms.  If the Company is unable to
obtain  such  financing,  it will be unable to close the  Superior  acquisition.
Concurrently with the completion of the proposed Superior acquisition,  Superior
and the Company  intend to enter into a line of credit to provide  financing for
Superior.  The Company and Superior are currently  engaged in discussions with a
commercial  bank regarding  such line of credit.  There can be no assurance that
the Company will be able to secure the line of credit or that the line of credit
will be available on favorable  terms. If the Company is unable to obtain a line
of credit for Superior, it will be unable to close the Superior acquisition. The
Company  intends  to fund  Superior's  operations  with the line of  credit  and
Superior's cash generated from operations.

 SPECIALTY PHARMACEUTICAL BUSINESS

    DynaGen's  specialty  or  emerging  pharmaceutical  business  strategy is to
create a business based on branded generic products and multi-drug  combinations
in convenient  packaging for specific  indications  and  treatments.  Physicians
routinely  prescribe  two or more  separate  drugs for the  treatment of several
common medical problems. These drugs are separately prescribed and dispensed but
are taken at  various  times  during the  course of the day as  directed  by the
physician. A major problem in such multi-drug therapies is lack of compliance by
the patient and therefore less than  desirable  therapeutic  efficacy.  For this
reason, the  Company  initially  intends  to focus its  efforts  in this area on
compliance enhancement packaging. DynaGen has identified near-term opportunities
in  compliance  enhancement  packaging  in the areas of women's  healthcare  and
respiratory infection.  The Company is developing convenience packaging which it
believes   will  provide   ease  of   prescription,   dispensing,   storage  and
self-administration.  Convenience packaging also provides cost advantages to the
consumer since there is only a single "co-pay" instead of multiple co-payments.

    The Company's  proposed  specialty  pharmaceutical  products are in an early
stage of  development  and  therefore  are subject to the risks of  unsuccessful
development,  marketing  and  commercialization.  These  proposed  products will
require  substantial  further  development  which may include clinical  testing,
bio-equivalency  studies and regulatory  approval,  all at a substantial cost to
the Company. The use of specialty pharmaceuticals will require the acceptance of
a new way of prescribing  medication and there can be no assurance a market will
develop   for  such   products.   Additional   investment   by  the  Company  in
manufacturing,  marketing and sales  infrastructures will also be required prior
to  commercialization.  No assurance can be given that these development efforts
will be  successfully  completed or that the products,  if  introduced,  will be
successfully  marketed.  See "Management's  Discussion and Analysis of Financial
Condition and Results of  Operations  -- Certain  Factors That May Affect Future
Results."

THERAPEUTIC PRODUCTS

 OVERVIEW OF SMOKING CESSATION THERAPY

    The rationale behind  currently  marketed  nicotine based smoking  cessation
products is that by gradually  decreasing the  concentration and daily dosage of
nicotine, one can overcome nicotine  dependency without experiencing  withdrawal
problems.   Nicorette(r),   a  nicotine-containing  gum  currently  marketed  by
SmithKline  Beecham  Consumer  Health Care, was the first  prescription  product
approved  by  the  FDA  as an  aid  to  smoking  cessation.  Nicotine-containing
transdermal  patches and nasal  sprays have also been  developed  and  initially
approved by the FDA for prescription use and marketed as such by  pharmaceutical
companies.  Beginning in 1996,  the FDA granted  approval  for several  nicotine
patch and gum products,  including some of the products  mentioned  above, to be
sold over-the-counter  ("OTC"),  without  prescription.  The FDA approval of OTC
products  has  caused  a  shift  in  the  smoking  cessation   marketplace  from
prescription to OTC use.

    Until   December   1993,   there  was  a   variety   of   non-FDA   approved
over-the-counter smoking cessation products. Several of these products contained
lobeline as their active ingredient  because it was believed that lobeline could
temporarily  replace  nicotine  and help to  overcome  nicotine  dependency  and
withdrawal  problems.  The majority of the lobeline  products  were taken orally
assuming  that a  sufficient  quantity  of lobeline  would be absorbed  from the
gastrointestinal ("GI") tract into the bloodstream.  These formulations have not
been proven to be effective and they have not received FDA approval.


                                       3


    DynaGen's  research is consistent with the hypothesis that lobeline relieves
nicotine  withdrawal  symptoms  by binding to  nicotine  receptors  in the brain
without activating the addiction mechanisms. Based on the belief that a lobeline
formulation  which does not depend on  absorption  from the GI tract might be an
effective  tobacco  substitute,   DynaGen  has  developed  alternative  delivery
formulations, focusing primarily on the sublingual tablet, NicErase-SL.

    NICERASE-SL.  DynaGen is developing NicErase-SL, a sublingual tablet that is
held under the tongue where it  dissolves  in one to three  minutes and releases
lobeline,  the active  ingredient of the tablet.  As the tablet  dissolves,  the
lobeline enters the bloodstream  directly through blood vessels under the tongue
and in the mouth.  NicErase-SL  is designed for use by  individuals  who want to
stop smoking. It is expected that NicErase-SL will be used in a six-week program
that  includes  smoking  cessation  counseling,  as is the  case for  other  FDA
approved prescription smoking cessation products.

    DynaGen has shown in clinical studies that  NicErase-SL  reduces symptoms of
tobacco  withdrawal and is now evaluating its effectiveness as an aid in smoking
cessation in a 750 subject  multi-center pivotal Phase 3 clinical trial. Results
from this first trial are  anticipated  to be available in the second quarter of
1997. At a minimum,  a second  similar trial would also be necessary  before the
Company could file with the FDA a New Drug Application to market  NicErase-SL as
a  prescription  product.  The FDA  currently  requires  that smoking  cessation
products be initially  marketed for  prescription  use with a possible switch to
OTC only after a positive  history of prescription  use has been established and
demonstrated to the FDA's satisfaction.

    In light of the shift in the smoking  cessation market from  prescription to
OTC products and of the expanding  availability  of different  dosage formats of
nicotine-based  smoking cessation products such as the nicotine nasal spray, the
Company is refocusing its traditional  development  strategy by concentrating on
outlicensing  its  technology  to one or more  strategic  partners.  The Company
intends to minimize research and development expenditures on products which have
a long development and approval process. Since alternative drug delivery formats
have proven successful in the nicotine  replacement  therapy market, the Company
is considering the development of additional delivery formats for NicErase, such
as a transdermal  patch and adhesive buccal wafer.  The Company  believes that a
product  available in multiple  delivery  dosage formats may create more diverse
marketing opportunities.

    In December 1996, DynaGen  licensed its technology for the  development of a
lobeline-containing  nasal spray to Nastech.  Under the terms of this agreement,
Nastech  will  be  responsible  for  all  remaining   preclinical  and  clinical
development  of the product.  DynaGen and Nastech will divide equally all future
license and sales royalty revenues.

    To date,  the Company has not entered  into any  collaborative  arrangements
with any third party with respect to the  development and  commercialization  of
NicErase,  except for the agreement with Nastech.  The Company's future NicErase
development and commercialization  activities will depend on a number of factors
including the results of the Company's  current  pivotal Phase 3 clinical  trial
for NicErase-SL,  the changing  demands of the smoking  cessation market and the
Company's ability to secure a suitable marketing and development partner.  There
can be no  assurance  that the results of the current  pivotal  Phase 3 clinical
trial will be sufficient to support further clinical  development of NicErase-SL
or a second pivotal Phase 3 clinical trial.  Even if such results are promising,
there can be no assurance that such results will be repeated in future  clinical
trials, or that the Company will receive the necessary  regulatory  approvals to
commercialize  NicErase-SL  or any  other  NicErase  format.  See  "Management's
Discussion  and Analysis of Financial  Condition  and Results of  Operations  --
Certain Factors That May Affect Future Results."

 ORTHODYN BIORESORBABLE BONE CEMENT

    The global orthopaedics market continues to expand, and the Company believes
that  resorbable  materials are one of the most rapidly  growing  sectors.  With
significant growth projected in the elderly population comes an increased demand
for orthopaedic  materials.  Advances continue to be made in the design of total
joint  prostheses and other fixation  devices.  The area of  bioresorbable  bone
substitutes is of prime interest to the major orthopaedics  manufacturers,  with
most having the goal of adding such materials to their product line.


                                       4



    OrthoDyn  is based on a family of  bioresorbable,  biocompatible  polyesters
derived  from  compounds  naturally  occurring  in the body.  It is a  composite
polymer/filler  system and has strength and stiffness more similar to human bone
than fully ceramic systems.  It is initially  moldable,  forming a very cohesive
dough,  cures fast (10 to 30 minutes) with little or no heat evolution,  and has
strength,  stiffness and toughness  similar to human bone.  Preclinical  studies
have  demonstrated  acceptable  specifications  with regard to degradation time,
biocompatibility   and  strength.   These  studies  also  have  provided   early
indications  that new bone effectively  grows into and replaces the cement.  The
polymer   component   also  has   potential   use  for  formation  of  preformed
bioresorbable pins, plates and screws.

    In line with DynaGen's goal to minimize development expenditures on products
which have long-term development and clinical approval programs, the Company and
Smith & Nephew have recently entered into an agreement  providing Smith & Nephew
with an exclusive  period of 12 months to evaluate the OrthoDyn  product's human
orthopaedic applications.  There can be no assurance that the Company will enter
into a definitive  agreement  with Smith & Nephew or that such an agreement will
prove  successful  for  DynaGen.  Furthermore,  no  assurance  can be given that
continued  preclinical  development  of OrthoDyn  will be  successful,  that the
necessary  regulatory  approvals will be obtained or that the OrthoDyn  products
will be  successfully  marketed.  See  "Management's  Discussion and Analysis of
Financial Condition and Results of Operations -- Certain Factors That May Affect
Future Results."

 ADDITIONAL BIORESORBABLE POLYMER TECHNOLOGIES

    Vaccine  delivery  represents a potential  area for the  application  of the
Company's  controlled  release delivery  systems.  DynaGen's patent  application
covering  its  Sleeper(tm)  technology  has  recently  been  granted  notice  of
allowance from the U.S. Patent and Trademark Office.  This technology involves a
unique  combination  of a  bioresorbable  polymer and a vaccine such that,  upon
injection,  the Sleeper delivery system immediately  releases the initial amount
of  vaccine  corresponding  to the first  shot and then,  after a  predetermined
period  of  time,  will  release  in  a  "burst"  the  second  load  of  vaccine
representing the "booster" shot.

    DynaGen  also has  developed  a polymer  system  that can be  applied to the
controlled,  sustained  release  of a wide  variety  of drugs.  The  Company  is
pursuing  both  corporate  alliances  and  outlicensing  approaches  for further
development of these resorbable polymer technologies.  There can be no assurance
that the Company will be able to find a suitable  development  partner for these
bioresorbable   polymer   technologies,   that  development  efforts  for  these
technologies will be successfully completed or that the products, if introduced,
will be  successfully  marketed.  See  "Management's  Discussion and Analysis of
Financial Condition and Results of Operations -- Certain Factors That May Affect
Future Results."

 OTHER THERAPEUTIC PRODUCTS

    The  Company  is also  conducting  early  stage  research  on a  proprietary
bacterial  extract for the  treatment  of  infectious  diseases and is currently
engaged in the characterization and partial purification of the extract prior to
filing an  investigational  new drug application.  Management is also evaluating
potential clinical applications for this technology. These types of therapeutics
have  been  studied  in the past and have had  mixed  results.  There  can be no
assurance that the Company can  successfully  develop,  test and market products
based on this technology. See "Management's Discussion and Analysis of Financial
Condition and Results of  Operations  -- Certain  Factors That May Affect Future
Results."

DIAGNOSTIC PRODUCTS

    The health  care  industry  has  shifted to a managed  care  approach  which
integrates prevention,  diagnostic, therapeutic and compliance technologies into
a panel of products for specific disease management. In light of this structural
shift,  the  Company is  developing  diagnostic  products  which may help in the
prevention and diagnosis of disease and in the  determination of compliance with
smoking cessation programs.

 BREAST BIOPSY TECHNOLOGY

    DynaGen  recently  licensed  technology  that is  intended  to  improve  the
accuracy and efficiency,  and reduce the overall cost, of breast surgical biopsy
procedures from BioLoc, a privately held Boston-based  company.  The acquisition
of the BioLoc  technology  fits  DynaGen's  strategy of  developing  distinctive
healthcare  products based on technologies  acquired by the Company from outside
sources.

    Core needle  biopsy,  the most  commonly  used  non-surgical  procedure  for
diagnosis of suspicious lesions in breasts, is limited in its ability due to the
difficulty in capturing the targeted  tissue and the need for multiple  attempts
to obtain  accurate  and  sufficient  samples,  resulting in  unnecessary  pain,
scarring  and  anxiety.  The BioLoc  technology  is  intended  to  overcome  the
shortcomings  of the core needle  biopsy  procedure  by  accurately  guiding the
surgical biopsy  instruments  directly to the suspected tissue lesion identified
during mammography  examination.  Imaging and location tracking technologies are
combined  to provide a  three-dimensional  view of the breast  tissue  which the
Company  believes  will allow the accurate  depiction  of the biopsy  target and
guidance  for its surgical  removal.  The Company is now  completing  its patent
application covering this technology and developing a prototype system.

    The BioLoc  technology is in an early stage of development  and therefore is
subject   to   the   risks   of   unsuccessful   development,    marketing   and
commercialization.  This  proposed  product  will  require  substantial  further
development and preclinical and clinical testing and regulatory  approval,  at a
substantial  cost  to the  Company.  Additional  investment  by the  Company  in
manufacturing,  marketing and sales  infrastructures will also be required prior
to  commercialization.  No assurance can be given that these development efforts
will be  successfully  completed or that the products,  if  introduced,  will be
successfully  marketed.  See "Management's  Discussion and Analysis of Financial
Condition and Results of  Operations  -- Certain  Factors That May Affect Future
Results."

 SMOKING CESSATION AND RELATED DIAGNOSTIC PRODUCTS

    NICCHECK I.  NicCheck I is a simple  colorometric  test for the detection of
nicotine and/or its metabolites in urine. The test distinguishes between smokers
and nonsmokers  with 97% accuracy and is also able to  distinguish  between high
and low  consumers  of  nicotine.  NicCheck  I can be used  both as a  companion
product for NicErase-SL or independently for clinical evaluation. The NicCheck I
result may be used to determine the  appropriate  level of nicotine  replacement
therapy during  smoking  cessation  efforts.  Smokers who are trying to quit may
become more motivated by observing a decrease in color intensity of the NicCheck
I results as they reduce nicotine consumption. NicCheck I may also prove to be a
cost-effective  means for  insurance  companies  to employ risk  assessment/risk
management strategies.  The FDA recently granted the Company clearance to market
NicCheck I in the United  States and the Company is now  attempting to establish
multilevel sales and marketing approaches.

    NICCHECK II. The Company is  initiating  preclinical  studies for  detecting
exposure to secondhand  smoke.  Secondhand smoke causes and exacerbates a number
of respiratory  problems in  nonsmokers.  The Company  believes that  physicians
could use NicCheck II to promote early intervention.

 TUBERCULOSIS DIAGNOSTIC PRODUCTS

    DynaGen  has  also  developed  proprietary   diagnostic  tests  for  certain
infectious  diseases  including  tuberculosis  ("TB").  The Company is currently
selling MycoDot(r), a product to detect antibodies against mycobacteria in blood
or  serum,  through  distributors  primarily  in  Southeast  Asia,  Pacific  Rim
countries,  China, India, and Japan.  DynaGen has received clearance under three
premarket  notification 510(k)s from the FDA to market its MycoAKT(r) diagnostic
tests that  identify  three  mycobacterial  species in culture.  The Company has
granted exclusive U.S.  manufacturing and distribution rights and semi-exclusive
worldwide rights for MycoAKT to a third party.  The Company  continues to pursue
licensing arrangements for the promotion and distribution of these products, but
does not expect to  generate  material  amounts  of revenue  from sales of these
products.



                                       6


SALES AND MARKETING

    The Company's  generic  therapeutic  products are sold through private label
arrangements  primarily  through  direct  sales  efforts  to  drug  wholesalers,
distributors and retail drug chains and other pharmaceutical  companies.  In the
near future, the Company also intends to market its generic therapeutic products
under its own "Able  Laboratories"  name.  The Company  markets  its  diagnostic
products under its own name primarily through distributors.

    The  Company has  relatively  limited  experience  in sales,  marketing  and
distribution.  There  can be no  assurance  that the  Company  can  successfully
implement its sales and marketing strategy or that it can successfully market or
sell any of its products or proposed products. See "Management's  Discussion and
Analysis of Financial  Condition and Results of  Operations  -- Certain  Factors
That May Affect Future Results."

MAJOR CUSTOMERS

    During the  Transition  Period,  approximately  85% of total  revenues  were
derived from three major  customers:  Schein  Pharmaceutical  ("Schein")  (53%),
Genelabs Diagnostic Pte LTD ("Genelabs") (18%) and Alpharma, Inc. (14%). For the
fiscal  year ended  June 30,  1996,  approximately  79% of total  revenues  were
derived from three major customers: Bristol-Myers Products ("BMP") (45%), Hainan
OSROC Bio-Tech Co. Ltd.  ("OSROC") (23%) and Remel LP ("Remel")  (11%).  For the
fiscal  year ended  June 30,  1995,  approximately  77% of total  revenues  were
derived  from two major  customers:  BMP (50%) and Genelabs  (27%).  There is no
assurance  that the revenues  from Schein and Genelabs  will recur.  The revenue
from BMP  represents  the  recognition  over two years of a one-time  payment of
$500,000 and will not recur.  In addition,  the revenue from Alpharma,  Inc. was
derived from a temporary  supply  agreement  which ended in February 1997 and is
not expected to recur.  The loss of any key  customer  and the  inability of the
Company to replace  revenues  provided by a key  customer  could have a material
adverse  effect on the Company's  business,  financial  condition and results of
operations.

INDUSTRY SEGMENTS AND SALES BY GEOGRAPHIC AREA

    Financial  information with respect to the Company's  business  segments and
product  sales  by  geographic  area  is  presented  in  Note  11 of  "Notes  to
Consolidated Financial Statements."

BACKLOG

    The  dollar  amount of  backlog  orders  for the  Company's  products  as of
December 31, 1996 was  approximately  $300,000.  Although  orders are subject to
cancellation  without penalty,  management  expects to fill substantially all of
them in the near future.

MANUFACTURING AND SUPPLIERS

    DynaGen's  generic  products  are  manufactured  at  its  Able  Laboratories
facility in South Plainfield,  New Jersey. The principal  components used in the
Company's  generic products are active and inactive  pharmaceutical  ingredients
and certain packaging materials. Sources for certain materials for the Company's
products must be approved by the FDA, and in many  instances only one source has
been  approved.  Active raw material  ingredients  are purchased  primarily from
United States  distributors  of bulk  pharmaceutical  materials  manufactured by
foreign  companies.   To  date,  the  Company  has  experienced  no  significant
difficulty  in  obtaining  raw  materials.  However,  if  raw  materials  from a
specified supplier were to become unavailable,  the Company would be required to
file a supplement to its ANDA and revalidate the manufacturing process using the
new  supplier's  materials.  If unexpected  delays in obtaining new materials do
occur,  it could  result in the loss of  revenues  and have a  material  adverse
effect on the Company's business, financial condition and results of operations.
See "Management's  Discussion and Analysis of Financial Condition and Results of
Operations -- Certain Factors That May Affect Future Results."

    The Company's strategy is to license its diagnostic products for manufacture
and  distribution  by third  parties.  The  Company  has  entered  into  license
agreements  for the  manufacture  and  distribution  of its  MycoAKT and MycoDot
products.  MycoDot  is  produced  by a single  licensed  manufacturer  in India.
Nicheck I is  produced  by a contract  manufacturer  in the United  States.  The
Company's  dependence upon third parties for the manufacture and distribution of
its diagnostic  products could have a material  adverse effect on its ability to
deliver its products on a timely basis.


                                       7


    Clinical supplies of the Company's proprietary NicErase-SL product candidate
are manufactured by a third-party contract manufacturer.

    The Company's  Cambridge,  Massachusetts  and South  Plainfield,  New Jersey
facilities are registered with the FDA and subject to current Good Manufacturing
Practices ("cGMP") as prescribed by the FDA.

COMPETITION

    The  Company   competes  with  other  generic   manufacturers,   specialized
biotechnology  companies  and  major  pharmaceutical  companies.  Many of  these
competitors possess substantially greater financial and other resources, such as
expertise in clinical trials, FDA submissions and marketing,  that are needed to
commercialize a pharmaceutical product.

    In the generic  pharmaceutical  market, the Company competes with off-patent
drug  manufacturers,   brand-name   pharmaceutical  companies  that  manufacture
off-patent   drugs,   the  original   manufacturers   of  brand-name  drugs  and
manufacturers  of new  drugs  that may be used for the same  indications  as the
Company's   products.   Revenues   and  gross   profit   derived   from  generic
pharmaceutical  products  tend to  follow  a  pattern  based on  regulatory  and
competitive factors unique to the generic  pharmaceutical  industry.  As patents
for brand name products and related  exclusivity  periods mandated by regulatory
authorities  expire,  the  first  generic  manufacturer  to  receive  regulatory
approval  for generic  equivalents  of such  products is usually able to achieve
relatively  high  revenues  and gross  profit.  As other  generic  manufacturers
receive  regulatory  approvals  on  competing  products,   prices  and  revenues
typically  decline.   Accordingly,  the  level  of  revenues  and  gross  profit
attributable to generic  products  developed and  manufactured by the Company is
dependent,  in part,  on its  ability  to  develop  and  introduce  new  generic
products, the timing of regulatory approval of such products, and the number and
timing of regulatory approvals of competing products.  In addition,  competition
in the United States generic pharmaceutical market continues to intensify as the
pharmaceutical  market  continues to intensify  as the  pharmaceutical  industry
adjusts  to  increased  pressures  to  contain  health  care  costs.  Brand name
companies  are  increasingly  selling  their  products  into the generic  market
directly by acquiring or forming strategic alliances with generic pharmaceutical
companies. No regulatory approvals are required for a brand name manufacturer to
sell  directly  or  through a third  party to the  generic  market,  nor do such
manufacturers  face any other  significant  barriers to entry into such  market.
These  competitive  factors may have a material  adverse effect on the Company's
ability to sell its generic products.

    In the field of nicotine  addiction,  the NicErase-SL product candidate will
compete with both  prescription  and OTC  products.  In  particular,  management
believes that the principal drug  competition for its proposed  NicErase product
is nicotine  chewing  gum,  nicotine  nasal spray and the  nicotine  patch which
several  pharmaceutical  companies,  such as SmithKline Beecham,  Hoechst Marion
Roussel,  McNeil Consumer Products Co. and Ciba  Self-Medication  have developed
and are  marketing  in the United  States and  elsewhere.  Competition  has been
increasing due to the FDA approval of several nicotine patch and gum products to
be sold OTC, without prescription (see "Overview of Smoking Cessation Therapy").
These FDA  approvals  have caused a shift in the smoking  cessation  marketplace
from  prescription  to  OTC  use.  Other  programs  that  emphasize   behavioral
modification approaches, such as hypnosis, will create additional competition in
the smoking  cessation  market.  There can be no  assurance  that the results of
pivotal  Phase 3  clinical  trials  will  prove  successful  for  the  Company's
NicErase-SL  product candidate or that it will receive the necessary  regulatory
approvals and even if such  approvals  are  obtained,  that such product will be
commercially successful.

    OrthoDyn,  the Company's  orthopedic  product  candidate,  will compete with
products  from a number of much  larger  companies  in the bone  repair  market,
including,  but not limited to, Johnson & Johnson Co.,  Pfizer  (Howmedica)  and
Bristol-Myers Squibb Co. (Zimmer).  There can be no assurance that the Company's
OrthoDyn product candidate will receive the necessary  regulatory  approvals and
even if such  approvals  are obtained  that such  product  will be  commercially
successful.

    Management  believes  that the  Company's  current and  proposed  diagnostic
products  will  compete  on the basis of price,  performance  and  technological
features such as speed of detection, absence of radioactive substance,  accuracy
and reliability.  Management believes that Gen-Probe, Inc. and Becton-Dickinson,
among  others,  are its  immediate  competitors  and that  other  companies  may
introduce competing products. There can be no assurance that the Company will be
able to successfully  market any of its diagnostic  products.  See "Management's
Discussion  and Analysis of Financial  Condition  and Results of  Operations  --
Certain Factors That May Affect Future Results."


                                       8


GOVERNMENT REGULATION

    The  Company's  therapeutic  and  diagnostic  products  will be  subject  to
significant  government  regulation in the United States principally by the FDA,
and  to  a  lesser  extent,  by  the  Drug  Enforcement  Administration,   state
governments  and other  countries.  Federal and state  regulations  and statutes
impose certain  requirements  on the testing,  manufacture,  labeling,  storage,
recordkeeping,  approval,  advertising and promotion of the Company's  products.
Noncompliance  with  applicable   requirements  can  result  in  judicially  and
administratively   imposed  sanctions   including  seizures  of  adulterated  or
misbranded  products,  injunction  actions,  fines  and  criminal  prosecutions.
Administrative  enforcement  measures can also involve  product  recalls and the
refusal of the government to approve new drug applications ("NDAs") or ANDAs. In
order  to  conduct  clinical  tests and produce  and  market  products for human
diagnostic  and  therapeutic   use,  the  Company  must  comply  with  mandatory
procedures and safety standards  established by the FDA and comparable state and
foreign regulatory agencies.  Typically, such standards require that products be
approved by the FDA as safe and effective for their  intended use prior to being
marketed for human applications.

    To obtain FDA approval for a new drug or generic  equivalent,  a prospective
manufacturer  must, among other things,  comply with the FDA's cGMP regulations.
The FDA may  inspect the  manufacturer's  facilities  to assure such  compliance
prior to approval or at any other  reasonable  time, and the Company must follow
cGMP  regulations at all times during the  manufacture  and other  processing of
drugs.  To comply  with the  requirements  set forth in these  regulations,  the
Company must continue to expend  significant time to provide adequate  resources
in the areas of development, production, quality control and quality assurance.

    FDA  approval  is  required  before  the  Company  can  market any new drug,
including a generic equivalent of a previously approved drug or a new indication
or delivery  method for a previously  approved drug.  There are three  principal
ways to obtain FDA approval of a new drug:

       1) New Drug Application  (NDA) -- A prospective  manufacturer must submit
    to the  FDA full reports of  well-controlled clinical studies and other data
    to prove that a drug is safe and effective and meets other  requirements for
    approval.

       2)  "Paper"  NDAs -- Under  certain  circumstances,  the FDA will  permit
    safety and efficacy to be demonstrated by submission of published literature
    and journal articles.

       3) Abbreviated New Drug  Applications  (ANDA) -- The  Waxman-Hatch Act of
    1984 established a statutory procedure for the submission and FDA review and
    approval of ANDAs for generic versions of drugs  previously  approved by the
    FDA. Under the ANDA procedure,  the FDA waives the requirement of conducting
    complete  clinical  studies of safety and  efficacy,  and instead  typically
    requires  the  applicant to submit data  illustrating  that the generic drug
    formulation is bioequivalent to a previously approved drug. "Bioequivalence"
    means  that the rate of  absorption  and the  levels of  concentration  of a
    generic  drug in the  body  needed  to  produce  a  therapeutic  effect  are
    substantially  equivalent to those of the previously approved drug. For some
    drugs,  the FDA may require  other means of  demonstrating  that the generic
    drug is  bioequivalent  to the  original  drug.  The NDA and  ANDA  approval
    process  generally  takes a number of years and involves the expenditure  of
    substantial resources.

    FDA  approval  of an NDA dealing  with a new  pharmaceutical  or  biological
product  for human use is a multistep  process.  Generally,  preclinical  animal
testing first must be conducted to establish  the safety and potential  efficacy
of the experimental product for treatment of a given disease or condition.  Once
the product has been found to be  reasonably  safe in animals,  suggesting  that
human  testing  would  be  appropriate,  an  investigational  new  drug  ("IND")
application  is submitted to the FDA. FDA acceptance of the IND allows a company
to initiate  clinical  testing on human subjects.  The initial phase of clinical
testing (Phase 1) is conducted to evaluate the safety and, if possible,  to gain
early  evidence  of  effectiveness  of the  experimental  product in humans.  If
acceptable  product safety is  demonstrated,  then Phase 2 trials are initiated.
The Phase 2 trials  involve  studies in a small  sample of the  actual  intended
patient   population  to  assess  the  efficacy  of  the  drug  for  a  specific
application,  to  determine  dose  tolerance  and the optimal  dose range and to
gather  additional  information  relating to safety and  potential  adverse side
effects.  Phase 2 studies are also utilized to evaluate combinations of products
for therapeutic  activity.  Once an  investigational  drug is found to have some
efficacy and an acceptable  safety profile in the targeted  patient  population,
Phase 3 trials may be initiated. Phase 3 trials are

                                       9


expanded  controlled trials that are intended to gather  additional  information
about safety and  effectiveness  in order to evaluate  the overall  risk-benefit
relationship  of the  experimental  product and to provide an adequate basis for
product  labeling.  These trials also may compare the safety and activity of the
experimental  product with currently available  products.  It is not possible to
estimate  the time in which  Phase 1, 2 and 3  studies  will be  completed  with
respect to a given  product,  although the time period can be as long as several
years.

    Upon completion of clinical testing,  which demonstrates that the product is
safe and  effective  for a  specific  indication,  an NDA or a  Product  License
Application  ("PLA") for a biological  product may be submitted to the FDA. This
application includes details of the manufacturing procedures, testing processes,
preclinical  studies and clinical trials. FDA first determines whether to accept
the application for filing. If it does, FDA's review commences;  if it does not,
the  Company  may  need  to  obtain  additional  data  before  resubmitting  the
application.  FDA approval of the  application is required  before the applicant
may market the new product.  In addition,  the FDA may impose  conditions on the
approval,  such as post-marketing testing and surveillance programs to monitor a
product's safety and effectiveness.

    The  Waxman-Hatch  Act  establishes   certain   statutory   protections  for
FDA-approved  drugs,  which protections  could preclude  submission or delay the
approval of a  competing  ANDA.  One such  provision  allows a five-year  market
exclusivity  period for NDAs  involving new chemical  compounds and a three-year
market exclusivity period for NDAs (including different dosage forms) containing
data  from  new  clinical  investigations  essential  to  the  approval  of  the
application.  Both patented and non-patented  drug products are subject to these
market exclusivity provisions.  Another provision of the act extends patents for
up to five years as compensation  for reduction of the effective  market life of
the patent  resulting  from the time involved in the federal  regulatory  review
process.

    The Orphan Drug Act also has market  exclusivity  provisions  of seven years
for the  first  approved  drug  for a rare  disease  or  condition.  A grant  of
exclusivity  under this act can preclude the approval of both NDAs and ANDAs for
the orphan indication.

    The  Prescription  Drug  User  Fee Act of 1992,  enacted  to  expedite  drug
approval  by  providing  the  FDA  with  resources  to hire  additional  medical
reviewers,  imposes three types of user fees on  manufacturers  of  NDA-approved
prescription drugs.  Applicants  submitting only ANDAs and most other off-patent
drug manufacturers,  including the Company,  are not currently subject to any of
the three user fees.  If the Company  submits  NDAs for non-ANDA  products,  the
Company will be subject to user fees.

    Penalties for wrongdoing in connection with the development or submission of
an  ANDA  were  established  by  the  Generic  Drug  Enforcement  Act  of  1992,
authorizing  the FDA to permanently or temporarily  bar companies or individuals
from  submitting  or  assisting  in the  submission  of an  ANDA.  They may also
temporarily deny approval and suspend  applications to market generic drugs. The
FDA may also  suspend the  distribution  of all drugs  approved or  developed in
connection  with  certain  wrongful  conduct and also has  authority to withdraw
approval of an ANDA under certain circumstances and to seek civil penalties. The
Company  does not  expect  the law to have a  material  impact on the  review or
approval of the Company's ANDAs.

    Reimbursement   legislation   such   as   Medicaid,    Medicare,    Veterans
Administration   and   other   programs   govern   reimbursement   levels.   All
pharmaceutical  manufacturers  rebate to individual states a percentage of their
revenues arising from Medicaid-reimbursed drug sales. Generic drug manufacturers
currently  rebate 11% of average net sales  price for  products  marketed  under
ANDAs. NDA  manufacturers are required to rebate the greater of 15.2% of average
net sales price or the difference between average net sales price and the lowest
net sales price during a specified period. The Company believes that the federal
and/or state  governments  may continue to enact measures in the future aimed at
reducing the cost of drugs and devices to the public. The Company cannot predict
the nature of such measures or their impact on the Company's profitability.

    The Company's manufacturing subsidiary, Able, currently manufactures several
products which are regulated as "old drugs" and subject to the  requirements  of
the Over-the-Counter Drug Review regulations  promulgated by the FDA. This class
of drugs requires no prior approval from FDA before marketing, but such products
must comply with  applicable  FDA  monographs  which specify, 


                                       10


among other things,  required  ingredients,  dosage  levels,  label contents and
permitted uses. These monographs may be changed from time to time, in which case
the Company may be required to change the formulation,  packaging or labeling of
any affected  product.  Changes to monographs  normally have a delayed effective
date,  so while the  Company  may have to incur  costs to  comply  with any such
changes, disruption of distribution is not likely.

    There are two principal  methods by which FDA  authorization may be obtained
to market medical device products,  such as the Company's  diagnostic test kits.
One method is to seek FDA  clearance  through a  premarket  notification  filing
under Section  510(k) of the Federal Food,  Drug,  and Cosmetic Act.  Applicants
under the 510(k)  procedure  must  prove  that the  device  for which  marketing
clearance is sought is substantially  equivalent to a device on the market prior
to the  Medical  Device  Amendments  of 1976  or a  device  marketed  thereafter
pursuant to the 510(k)  procedure.  The review period for a 510(k) submission is
generally shorter than that of a premarket approval ("PMA") procedure,  however,
it cannot be estimated with any degree of certainty.

    If the 510(k)  procedure is not applicable,  a PMA must be obtained from the
FDA. Under the PMA procedure,  the applicant must conduct  substantial  clinical
testing that is required to determine  the safety,  effectiveness  and potential
hazards of the  product.  Clinical  testing  requires  prior review of the study
protocol by an institutional review board ("IRB") and patients informed consent,
and may require submission of an investigational device exemption application to
the FDA (for significant risk devices).  Prior to human testing,  animal testing
may be required to determine the safety of the product.  The review period under
a PMA application is generally longer than review of a 510(k) and it may include
review of the  application  by an outside  advisory  committee of experts in the
field. In addition,  the preparation of a PMA application is significantly  more
complex, expensive and time consuming than the 510(k) procedure and no assurance
can be given  that the FDA will  grant  approval  for the sale of the  Company's
products  for  routine  clinical  applications  or that the  length  of time the
approval process will require will not be extensive.

    The FDA can also  significantly  delay the approval of a pending NDA,  ANDA,
510(k) or PMA under its "Fraud,  Untrue  Statements of Material Facts,  Bribery,
and Illegal  Gratuities  Policy."  Manufacturers  of drugs and devices must also
comply with the FDA's cGMP standards or risk sanctions such as the suspension of
manufacturing  or the seizure of drug  products and the FDA's refusal to approve
additional applications.

    In addition,  if the Company  elects to  manufacture  its drugs,  devices or
biological   products  itself,  it  will  be  necessary  to  meet  mandated  FDA
manufacturing   requirements  by  applying  for  appropriate  FDA  establishment
registration  such  as  an  Establishment  License  Application  for  biological
products,  Drug  Establishment  Registration  for its drug products and a Device
Establishment Registration for devices.

    There can be no assurance that the  appropriate  approvals from the FDA will
be granted as to any of the Company's  proposed products or processes,  that the
process to obtain such approvals  will not be excessively  expensive or lengthy,
or that the Company will have  sufficient  funds to pursue such  approvals.  The
failure to  receive  the  requisite  approvals  for the  Company's  products  or
processes,  when and if  developed,  or  significant  delays in  obtaining  such
approvals,  would  prevent  the Company  from  commercializing  its  products as
anticipated  and  would  have a  materially  adverse  effect  on  the  business,
financial condition and results of operations of the Company.  See "Management's
Discussion  and Analysis of Financial  Condition  and Results of  Operations  --
Certain Factors That May Affect Future Results."

    Able is subject to a consent decree entered by the court on April 9, 1992 in
United States v. Able Laboratories,  Inc., Civ. No. 91-4916 (D.N.J.) for failure
to comply with FDA cGMP and has been  operating  under this consent decree since
April 1992. The principals  involved in the issuance of that order are no longer
employed by Able,  DynaGen or any of its  affiliates.  Since the  acquisition by
DynaGen, Able has made substantial  commitments (both directed and financial) to
improve the plant, personnel, and equipment in order to effect an improvement in
its operations.  Key management changes have been made with individuals who have
knowledge and commitment for cGMP in order to ensure  continued cGMP compliance.
Ongoing cGMP  training on a regularly  scheduled  basis will also be provided to
Able's employees.

    Additionally, the latest Establishment Inspection, conducted on November 12,
13, 18, and 19, 1996 under the authority of an Order of Permanent Injunction did
not result in the issuance of an FDA Form 483, and the Establishment  Inspection
Report (EIR) classified the inspection as "NN" -- no official action  indicated.
The Company is in the process of initiating changes and plans to request the FDA
to join Able in a petition for relief from the consent decree.

PRODUCT LIABILITY AND INSURANCE COVERAGE

    The Company presently maintains product liability insurance in the amount of
$3,000,000  for its  products  presently  being  marketed.  The Company does not
presently maintain product liability  insurance on any of its proposed products.
Although, the Company intends to obtain product liability insurance prior to the
commercialization of certain products which are not presently insured, there can
be no assurance that the Company will obtain such  insurance at favorable  rates
or, even if obtained,  that any  insurance  will be adequate to cover  potential
liabilities.

    In the event of a  successful  suit against the  Company,  insufficiency  of
insurance  coverage  could have a  materially  adverse  impact on the  Company's
operations  and  financial  condition.  Furthermore,  the costs of  defending or
settling a product liability claim and any attendant negative publicity may have
a  materially  adverse  impact on the  Company,  even if the Company  ultimately
prevails.  Furthermore,  certain food and drug retailers require minimum product
liability  insurance  coverage as a  precondition  to  purchasing  or  accepting
products  for  commercial  distribution.  Failure  to  satisfy  these  insurance
requirements  could impede the  Company's  ability to achieve  broad  commercial
distribution  of its proposed  products,  which could have a materially  adverse
effect upon the business and financial condition of the Company.

RESEARCH AND DEVELOPMENT

    For the Transition Period,  the Company expended  $1,092,253 on research and
development activities. For the fiscal years ended June 30, 1996, 1995 and 1994,
the Company expended  $3,118,145,  $1,718,006 and $2,183,849,  respectively,  on
research and development activities.

PATENTS AND PROPRIETARY TECHNOLOGY

    As part of its initial  organization,  the Company  acquired several patents
related to the polymer technologies.  In addition, the Company has filed several
U.S. and foreign patent  applications for processes and products relating to its
controlled  release delivery  systems,  smoking cessation  technology,  nicotine
detection product,  bioresorbable bone cement product,  immunological  tests for
the diagnosis of mycobacterial disease, and other technologies. No assurance can
be given that existing patent  applications will be granted or that any patents,
if issued,  will provide the Company with  adequate  protection  relating to the
covered products, technology or processes.

    To date, the Company has received two U.S.  patents  related to its NicErase
smoking cessation technology  covering:  (i) the transdermal delivery system for
the  administration  of  lobeline  as an  aid  to  smoking  cessation  and  (ii)
sublingual tablet  formulations.  The Company has received a U.S. patent related
to a controlled release delivery system for drug dependency.  In April 1997, the
Company  received  a notice of  allowance  from the U.S.  patent  office for the
Company's pulsed release vaccine delivery technology. Competitors may have filed
applications  for,  or may have been  issued  patents or may  obtain  additional
patents and proprietary  rights  relating to, products or processes  competitive
with  those of the  Company.  Accordingly,  there can be no  assurance  that the
Company's  patent  applications  will result in patents being issued or that, if
issued,  the patents will afford  protection  against  competitors  with similar
technology;  nor can  there be any  assurance  that any  patents  issued  to the
Company will not be infringed or  circumvented by others or that others will not
obtain patents that the Company would need to license or  circumvent.  There can
be no assurance that licenses that might be required for the Company's processes
or products  would be available  on  reasonable  terms,  if at all. In addition,
there can be no assurance that the Company's patents,  if issued,  would be held
valid by a court.

    The Company's  generic and  specialty  pharmaceutical  businesses  rely upon
unpatented  trade  secrets  and  proprietary   technologies  and  processes.  No
assurance can be given that others will not independently  develop substantially
equivalent  proprietary  information  and techniques or otherwise

                                       12


gain access to the Company's trade secrets or disclose such technology,  or that
the Company can meaningfully  protect its right to unpatented trade secrets. The
Company  requires  its  employees,  consultants  and other  advisors  to execute
confidentiality agreements. However, there is no assurance that these agreements
will provide meaningful  protection or adequate remedies for the Company's trade
secrets in the event of unauthorized use or disclosure of such information.

    The manufacture and sale of certain  products  developed by the Company will
involve the use of processes,  products or information, the rights to certain of
which are owned by others.  Although  the Company  has  obtained  licenses  with
regard to the use of certain of such processes, products and information,  there
can be no assurance  that such  licenses will not be terminated or expire during
critical  periods,  that the Company  will be able to obtain  licenses for other
rights which may be important to it, or, if obtained, that such licenses will be
obtained on  commercially  reasonable  terms. If the Company is unable to obtain
such licenses,  the Company may have to develop alternatives to avoid infringing
patents of others,  potentially  causing  increased  costs and delays in product
development  and  introduction,  or  precluding  the  Company  from  developing,
manufacturing or selling its proposed  products.  Additionally,  there can be no
assurance   that  the  patents   underlying  any  licenses  will  be  valid  and
enforceable.  To the extent any  products  developed by the Company are based on
licensed technology,  royalty payments on the licenses will reduce the Company's
gross profit from such product  sales and may render the sales of such  products
uneconomical.

    MycoDot(R),   NicErase(R),   MycoAKT(R),  NicCheck(R)  and  OrthoDyn(R)  are
registered trademarks of the Company. Sleeper(tm) is a trademark of the Company.

EMPLOYEES

    As of April 24,  1997,  the  Company  and its  subsidiary  had 67  full-time
employees,  of whom 16 were  employed  in selling,  general  and  administrative
activities and 51 were employed in research and development and manufacturing of
its products. Six of the Company's employees hold doctoral degrees including one
who holds a Doctorate in Medicine  (M.D.).  None of the Company's  employees are
represented by a union. The Company believes its relationship with its employees
is good.

ITEM 2. PROPERTIES

    The  Company  maintains  its  principal  executive  offices  and  laboratory
facilities at 99 Erie Street in Cambridge,  Massachusetts.  The premises,  which
consist  of  approximately  27,000  square  feet of space,  are  leased  from an
unaffiliated party, for a term expiring on September 30, 1997.

    The Able  Laboratories  subsidiary is located at a 46,000 square foot leased
manufacturing facility in South Plainfield,  New Jersey. The premises are leased
from an unaffiliated party for a term expiring on March 31, 2000.

    The Company  believes that its present  facilities  are adequate to meet its
current needs. If new or additional space is required, the Company believes that
adequate   facilities  are  available  at  competitive  prices  in  the  Boston,
Massachusetts and South Plainfield, New Jersey metropolitan
areas.

ITEM 3. LEGAL PROCEEDINGS

    The Company is  involved  in certain  legal  proceedings  incidental  to its
normal business activities.  While the outcome of any such proceedings cannot be
accurately  predicted,  the Company does not believe the ultimate  resolution of
any existing  matters  should have a material  adverse  effect on its  financial
position or results of operations.

ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

    No matters were submitted to a vote of security holders, whether through the
solicitation of proxies or otherwise, during the Transition Period.

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

OVERVIEW

    The Company  develops and markets  proprietary  and generic  therapeutic and
diagnostic  products  for the human  healthcare  market.  The  Company has begun
expanding its business focus from being a development  and licensing  company to
building  a  diversified  healthcare  company  focused  on the  manufacture  and
distribution of generic drug products and specialty  pharmaceuticals  as well as
the continued  development of therapeutic and diagnostic  products.  The Company
intends to  implement  this  strategy  through the  acquisition  of  businesses,
technologies  and products that the Company  believes are undervalued as well as
through internal product  development.  In August 1996, the Company acquired the
tablet business of Able Laboratories,  Inc. ("Able"),  a generic  pharmaceutical
product  subsidiary  of Alpharma,  Inc. In  addition,  the Company has signed an
agreement  to purchase all of the  outstanding  shares  Superior  Pharmaceutical
Company ("Superior"), a distributor of generic pharmaceuticals.  

    The Company has financed its operations  primarily through the proceeds from
its public and private stock offerings,  a convertible note and limited revenues
from  product  sales  and  technology  license  fees and  royalties.  Management
anticipates  that revenues from product sales will not be sufficient to fund its
current operations or produce an operating profit until such


                                       15


time as the Company is able to  establish  acceptance  of its  products in their
respective  markets  and expand  its  distribution  channels.  The  Company  has
incurred  losses since  inception and expects to incur  additional  losses until
such  time as it is able  to  successfully  develop,  manufacture,  and  sell or
license its existing and proposed products and technologies.

RESULTS OF OPERATIONS

    TRANSITION PERIOD ENDED DECEMBER 31, 1996 COMPARED WITH THE SIX MONTH
    PERIOD ENDED DECEMBER 31, 1995

    REVENUES

    Revenues for the six month period ended  December 31, 1996 (the  "Transition
Period") were  $360,000  versus  $333,000 for the six months ended  December 31,
1995.  This increase of $27,000 is a result of an increase in Able product sales
partially  offset by a decrease  in fee revenue  which was due to one-time  fees
from Bristol-Meyers Products recognized during the six months ended December 31,
1995.  The increase in product sales resulted from the Company  realizing  sales
from its Able subsidiary since its acquisition on August 19, 1996. The Company's
product sales also increased due to improved diagnostic products sales.

    COST OF SALES

    Cost of sales was 99% of product sales for the  Transition  Period  compared
with 50% for the six months  ended  December 31,  1995.  Tablet and  suppository
production  at Able  during the  Transition  Period did not  support the minimum
level of fixed manufacturing costs required at the facility.  Management expects
that the cost of product sales, as a percentage of sales, will decrease as sales
orders and production volumes increase.

    RESEARCH AND DEVELOPMENT EXPENSES

    Research and development  expenses for the Transition Period were $1,092,000
versus  $1,037,000  for the six months ended  December 31, 1995,  an increase of
$55,000.  This increase is primarily  attributable to costs  associated with the
ongoing NicErase-SL Phase 3 clinical trial and the Company's efforts in filing a
510(k)  application  with  the  U.S.  Food  and  Drug   Administration  for  its
NicCheck(R)  product.  The Company is also conducting  early stage research on a
bacterial extract for the treatment of infectious diseases.

    SELLING, GENERAL AND ADMINISTRATIVE EXPENSES

    Selling,  general and administrative expenses for the Transition Period were
$3,239,000  versus  $1,189,000  for the six months ended  December 31, 1995,  an
increase of  $2,050,000.  The  increase in selling,  general and  administrative
expenses is primarily due to  additional  payroll and plant  operating  costs of
approximately  $793,000 resulting from the acquisition of Able. In addition, the
Company  incurred  additional  costs of  approximately  $865,000  for the use of
business  consultants to develop,  seek and obtain alliances for certain Company
products,  potential  products and financial  development.  The Company incurred
additional  costs of  approximately  $80,000  towards  patent  applications  for
several of its products.  Legal  expenses  increased by  approximately  $106,000
primarily related to assistance with technology licensing,  pending acquisitions
and  corporate  regulatory  filings.  The  remainder is due to a net increase in
other operating expenses.

    OTHER INCOME (EXPENSE)

    Investment  income  increased by $46,000  from  $112,000 to $158,000 for the
Transition  Period as compared to same  period  ended  December  31,  1995.  The
Company had greater funds available for investment  during the Transition Period
compared to the six months ended December 31, 1995.

    The  Company  incurred  interest  expense  of  $74,000  and  amortized  debt
financing  costs of $62,000 during the Transition  Period,  both associated with
the $2,000,000 convertible note issued in 1996.

                                       16


    INCOME TAXES

    There were no provisions for income taxes for the Transition  Period and the
six months  ended  December  31, 1995 due to  operating  losses  incurred by the
Company and  valuation  reserves  applied  against  deferred  tax assets.  As of
December  31, 1996 and  December  31,  1995,  for  Federal and state  income tax
reporting  purposes,  the  Company  had  net  operating  loss  carryforwards  of
approximately $23,460,000 and $19,270,000 respectively. In addition, the Company
had  Federal  and state  research  tax  credit  carryforwards  of  approximately
$583,000 and $120,000, respectively, available to reduce future tax liabilities.

    YEAR ENDED JUNE 30, 1996 COMPARED TO YEAR ENDED JUNE 30, 1995

    REVENUES

    Revenues  for the year ended June 30, 1996  ("Fiscal  1996")  were  $556,000
versus $498,000 for the year ended June 30, 1995 ("Fiscal 1995").  This increase
of $58,000 is a result of an  increase  in license  fees of $85,000  offset by a
$27,000  decrease  in product  sales.  The  increase  in license  fee revenue is
attributable to one-time license fees received under  distribution  arrangements
for the  Company's  MycoAKT and  MycoDot  products.  MycoDot and MycoDyn  Uritec
product  sales  remained  consistent  between  Fiscal 1996 and Fiscal 1995.  The
decrease in total product sales resulted from lower  shipments of other products
in Fiscal 1996.

    COST OF SALES

    Cost of product  sales was 44% of net product  sales in Fiscal 1996 compared
to 54% in  Fiscal  1995.  This  decrease  in the  cost of  sales  percentage  is
primarily  attributable  to a  reallocation  of certain  manufacturing  staff to
product marketing and support roles.

    RESEARCH AND DEVELOPMENT EXPENSES

    Research and  development  expenses were  $3,118,000  for Fiscal 1996 versus
$1,718,000  for Fiscal  1995,  an  increase  of  $1,400,000.  This  increase  is
primarily due to  approximately  $1,200,000 in  additional  therapeutic  product
development  costs and $285,000 in  compensation  expense  resulting  from stock
grants.  The increase in therapeutic  development is mainly  attributable to the
initiation of the first of two planned  pivotal Phase 3 clinical  trials for the
Company's NicErase-SL smoking cessation product.

    The increase in research and development  expenses was partially offset by a
decrease in diagnostic  product  development  costs of $74,000.  The Company has
limited diagnostic product development  primarily to NicCheck,  a test to detect
the presence of nicotine.

    SELLING, GENERAL AND ADMINISTRATIVE EXPENSES

    Selling, general and administrative expenses for Fiscal 1996 were $2,685,000
versus $1,984,000 for Fiscal 1995, an increase of $701,000. Selling, general and
administrative  expenses increased in the following areas:  staffing - $355,000,
investor  relations - $165,000,  consulting - $111,000 and legal - $62,000.  The
increase  in  investor  relations  expenses  is  attributable  to a new  program
designed to inform  investors  on corporate  developments  and  strategy.  Legal
expenses increased primarily for assistance with certain licensing arrangements,
regulatory issues,  stock grants and options.  The increase in staffing expenses
is primarily due to the award of stock grants and options.  Consulting  expenses
relate to  assistance  provided  towards  developing  a  strategy  for  business
alliances for certain Company products.

    OTHER INCOME (EXPENSE)

    The  increase  in  investment  income  is  primarily  due to  greater  funds
available for investment  during Fiscal 1996. The increases in interest  expense
and  debt  financing  cost  amortization  are  attributable  to  the  $2,000,000
convertible note issued in 1996.

    INCOME TAXES

    There were no  provisions  for income  taxes for Fiscal 1996 and Fiscal 1995
due to operating  losses incurred by the Company and valuation  reserves applied
against deferred tax assets.


                                       17


    YEAR ENDED JUNE 30, 1995 COMPARED TO YEAR ENDED JUNE 30, 1994

    REVENUES

    Revenues for Fiscal 1995 were  $498,000  versus  $437,000 for the year ended
June 30, 1994 ("Fiscal 1994").  This increase of $61,000, or 14%, is a result of
an  increase in  diagnostic  product  sales of $248,000  offset by a decrease in
contract  service  revenue  of  $138,000  and a  decrease  in  license  fees and
royalties  of  $49,000.  Product  sales were  realized  primarily  from sales of
MycoDot, a tuberculosis  antibody  detection product,  to a distributor in Asia.
The Company also recognized fee revenue of $250,000 from Bristol-Myers  Products
("BMP").  The Company  granted BMP the right to evaluate  its smoking  cessation
technology for which the Company received a $500,000 payment,  of which $250,000
was  deferred as revenue  until  Fiscal  1996.  In July 1995,  BMP  informed the
Company that it decided not to exercise its option to license the  technology as
BMP's strategic interest was in developing an over-the-counter smoking cessation
product. The Company's  NicErase-SL smoking cessation product is being developed
for prescription use. In Fiscal 1994,  royalties were attributable to a one-time
payment  under  an  agreement  to  license   certain   tuberculosis   diagnostic
technology.  Contract  service revenues for Fiscal 1994 related to the Company's
development of a vaccine delivery system under a U.S. Army contract completed in
Fiscal 1994. The Company is no longer performing any contract development work.

    COST OF SALES

    Cost of product sales for Fiscal 1995 was 54% of net product sales.

    RESEARCH AND DEVELOPMENT EXPENSES

    Research and  development  expenses were  $1,718,000  for Fiscal 1995 versus
$2,184,000  for Fiscal 1994, a decrease of $466,000 or 21%. In Fiscal 1995,  the
Company  expended  $1,476,000 on therapeutic  product  development  and $242,000
towards  diagnostic  product  development,  compared to $1,500,000 and $684,000,
respectively,  in Fiscal 1994.  This is  reflective  of the  Company's  strategy
whereby  resources were directed  towards  NicErase-SL  development with limited
expenditures  towards other  therapeutic  and  diagnostic  product  development.
During  Fiscal  1995,  therapeutic  product  development  focused  primarily  on
NicErase-SL,  as the  Company  completed a  multi-center  pilot Phase 3 clinical
trial.

    Diagnostic product development  included limited development efforts for the
Company's  NicCheck and MycoAKT  products.  In March 1995, the Company  received
clearance from the FDA to market the MycoAKT  products and is currently  seeking
and evaluating  strategic alliances with third parties.  MycoAKT diagnostic test
kits are used to identify three mycobacterial species. The Company continued its
manufacturing  development scale-up and regulatory approval efforts with respect
to NicCheck, a nicotine detection product.

    SELLING, GENERAL, AND ADMINISTRATIVE EXPENSES

    Selling, general and administrative expenses for Fiscal 1995 were $1,984,000
versus $1,997,000 for Fiscal 1994, a decrease of $13,000.  Comparing Fiscal 1995
to Fiscal  1994,  savings  realized  from  decreases  in  salaries  and  related
benefits, public relations expenditures, use of outside business consultants and
travel expenses were offset by increases in product  marketing and support costs
and business insurance.  Product marketing and support efforts focused primarily
on  the  implementation  of  distribution   arrangements  (including  sales  and
marketing  support in connection with such  distribution  arrangements)  for the
Company's  tuberculosis  related  diagnostic  products and business  development
efforts for NicCheck.

    OTHER INCOME (EXPENSE)

    Investment  income  increased  by $113,000  from  $183,000 to $296,000  when
comparing  Fiscal 1994 to Fiscal 1995.  The Company had greater funds  available
for investment during Fiscal 1995 as a result of the Company's March 1994 public
offering.

    INCOME TAXES

    There were no  provisions  for income  taxes for Fiscal 1995 and 1994 due to
operating losses incurred by the Company.

                                       18



    DISCONTINUED OPERATIONS

    In May 1994,  the Company sold certain  assets of its contract  research and
development  business  that related to the Company's  fluid  systems  consulting
services  ("FSD").  The Company sold  accounts  receivable,  work in process and
certain  furniture and equipment for $165,000,  and assigned to the buyer all of
the outstanding  consulting  projects.  In addition,  the Company entered into a
sub-lease  agreement  whereby  the  buyer  occupies  the  space  used by the FSD
business.  This  transaction  resulted  in a loss on  disposal  of  $13,000.  In
management's opinion,  these services did not fit the strategic direction of the
Company's core  therapeutic and diagnostic  business.  Moreover,  these services
were not expected to be a significant source of revenues, profit or cash flow to
the Company in the future.

LIQUIDITY AND CAPITAL RESOURCES

    As of December  31,  1996,  the Company  had working  capital of  $5,502,000
versus  working  capital of  $10,204,000  at June 30, 1996.  Cash and investment
securities  were  $5,117,000 at December 31, 1996 as compared to  $10,464,000 at
June 30, 1996.  Working  capital was used primarily for research and development
and to fund  the  purchase  of Able and its  operations  during  the  Transition
Period.

    As  discussed in Note 2 to the  financial  statements,  in August 1996,  the
Company  acquired  certain  assets of Able,  a generic  pharmaceutical  products
subsidiary  of Alpharma  Inc.,  for  $550,000 in cash and  acquisition  costs of
$150,000.  Able  manufactures  and  markets  prescription  and  over-the-counter
pharmaceuticals from a 46,000 square foot leased manufacturing facility in South
Plainfield,  New Jersey.  DynaGen  obtained the rights to several  approved ANDA
products  through this purchase.  DynaGen plans to increase sales of its generic
product  portfolio by expanding Able's  distribution  network,  by reintroducing
discontinued  products and by developing new ANDA products.  The acquisition has
increased revenues,  costs and expenses,  capital expenditures and net cash used
for operating  activities.  DynaGen intends to fund Able's  operations  until it
becomes  self-supporting.  There can be no  assurance  that the Company  will be
successful  in  assimilating  this or any future  acquisition  or that Able will
generate sufficient revenues to become self-supporting.

    Management anticipates that the available working capital will be sufficient
to fund the current level of operations,  including the Able  business,  through
June 1997, but that the available working capital will not be sufficient to fund
the  acquisition  of Superior.  The Company has realized  limited  revenues from
license fees and the sale of its diagnostic  products.  Its future prospects and
revenue  potential from product sales cannot be determined with any certainty at
this time.

    The  Company  plans  to raise  capital  in order  to  finance  the  proposed
acquisition  of  Superior  through the sale of its  securities.  There can be no
assurance  that the Company  will be able to secure this  financing or that such
financing  will be  available on  favorable  terms.  If the Company is unable to
obtain  such  financing,  it will be unable to close the  Superior  acquisition.
Concurrently with the completion of the proposed Superior acquisition,  Superior
and the Company  intend to enter into a line of credit to provide  financing for
Superior.  The  Company  and  Superior  are  currently  in  discussions  with  a
commercial  bank regarding  such line of credit.  There can be no assurance that
the Company will be able to secure the line of credit or that the line of credit
will be available on favorable  terms. If the Company is unable to obtain a line
of credit for Superior, it will be unable to close the Superior acquisition. The
Company  intends  to fund  Superior's  operations  with the line of  credit  and
Superior's cash generated from operations.

    The Company also continues to pursue additional  sources of capital in order
to fund the growth of the Able generic drug business and its product development
efforts.  The Able  financing may take the form of a line of credit or equipment
notes or leases.  There can be no  assurance  that the  Company  will be able to
secure  additional  financing  for the Able  business or its  continued  product
development  efforts or that financing will be available on favorable  terms. If
the Company is unable to obtain such additional financing, the Company's ability
to maintain its current  level of operations  would be materially  and adversely
affected  and the  Company will be  required  to  reduce  or  eliminate  certain
expenditures,  including its research and  development  activity with respect to
certain proposed products.

ENVIRONMENTAL LIABILITY

    The Company has no known material environmental violations or assessments.


                                       19


RECENT ACCOUNTING PRONOUNCEMENTS

    The Company adopted Statement of Financial Accounting Standards ("SFAS") No.
121,  "Accounting  for the  Impairment of Long-Lived  Assets and for  Long-Lived
Assets  to Be  Disposed  Of" and  SFAS  No.  123,  "Accounting  for  Stock-Based
Compensation" in the Transition  Period. As discussed in Note 1 to the financial
statements,  the  adoption  of SFAS No.  121 and No. 123 did not have a material
effect on the  Company's  financial  position,  results of  operations  and cash
flows.

    The Financial  Accounting Standards Board issued SFAS No. 128, "Earnings per
Share," in February 1997. SFAS No. 128  establishes  standards for computing and
presenting earnings per share, and is effective for financial  statements issued
for  periods  ending  after  December  15,  1997.  Earlier  application  is  not
permitted.  SFAS No. 128 requires the restatement of all  prior-period  earnings
per share data presented.

CERTAIN FACTORS THAT MAY AFFECT FUTURE RESULTS

    The Company does not provide forecasts of its future financial  performance.
However,  from time to time,  information  provided by the Company or statements
made by its employees may contain  "forward  looking"  information that involves
risks and uncertainties.  In particular,  statements contained in this Form 10-K
that  are not  historical  facts  (including,  but not  limited  to,  statements
contained in "Item 1. Business"  relating to the Company's strategy with respect
to the  development  and marketing of the  Company's  products and to statements
contained  in  "Item  7.  Management's  Discussion  and  Analysis  of  Financial
Condition  and  Results  of  Operations"   relating  to  liquidity  and  capital
resources)  constitute  forward  looking  statements and are made under the safe
harbor provisions of the Private  Securities  Litigation Reform Act of 1995. The
Company's  actual results of operations and financial  condition have varied and
may in the future vary  significantly  from those stated in any forward  looking
statements. Factors that may cause such differences include, without limitation,
the risks,  uncertainties and other information discussed within this Form 10-K,
as well as the  accuracy  of the  Company's  internal  estimates  of revenue and
operating expense levels.

    The following  discussion of the  Company's  risk factors  should be read in
conjunction  with the  financial  statements  and  related  notes  thereto.  The
following factors, among others, could cause actual results to differ materially
from those contained in forward looking statements  contained or incorporated by
reference in this report and  presented by  management  from time to time.  Such
factors,  among others,  may have a material  adverse  effect upon the Company's
business, results of operations and financial condition.

    History of Losses;  Anticipation of Future Losses.  The Company has incurred
operating  losses  since  its  inception  and  has  an  accumulated  deficit  of
$24,315,191  as of  December  31,  1996.  The  Company  incurred  a net  loss of
$4,306,140 for the Transition Period ended December 31, 1996, as compared with a
net loss of $1,809,816  for the same period ended December 31, 1995. The Company
incurred  a net loss of  $5,097,419  for the fiscal  year  ended June 30,  1996,
compared with a net loss of $3,042,383  for the fiscal year ended June 30, 1995.
Such losses have resulted  principally  from  expenses  incurred in research and
development  and from  general  and  administrative  costs  associated  with the
Company's  development  efforts.  The  continued  development  of the  Company's
products will require the commitment of substantial resources to conduct further
development and preclinical and clinical trials, and to establish manufacturing,
sales, marketing,  regulatory and administrative capabilities.  In addition, the
Company's recently acquired subsidiary,  Able, has incurred net operating losses
in the past.  The Company  expects to provide its Able  subsidiary  with working
capital during the foreseeable future until Able can become self-supporting. The
Company  expects to incur  substantial  operating  losses over the next  several
years as its product  programs  expand,  various  clinical  trials  commence and
marketing  efforts are launched.  The amount of net losses and the time required
by the Company to reach  sustained  profitability  are highly  uncertain  and to
achieve  profitability,  the  Company  must,  among other  things,  successfully
complete development of its products, obtain regulatory approvals, and establish
manufacturing and marketing  capabilities by itself or with third parties. There
is no assurance  that the Company  will ever  generate  substantial  revenues or
achieve profitability.


                                       20



    Future Capital Needs;  Uncertainty of Additional  Funding. It is anticipated
that the Company will continue to expend significant  amounts of capital to fund
its  research  and  development,  clinical  trials  and  generic  pharmaceutical
business  and the proposed  acquisition  of Superior.  The  Company's  available
working  capital is  inadequate  for  completion  of the  Company's  development
programs,  and additional  financing will be necessary for the continued support
of the Company's  proposed products and operations,  including the establishment
of  manufacturing,  marketing  and  distribution  capabilities  for its proposed
products and the continued  operations of Able.  There can be no assurance  that
the Company will be able to secure  additional  financing or that such financing
will be available on  favorable  terms.  If the Company is unable to obtain such
additional  financing,  the  Company's  ability to maintain its current level of
operations  would be materially  and adversely  affected and the Company will be
required  to  reduce  its  overall  expenditures   including  its  research  and
development activity with respect to certain proposed products.

    In  addition,  the Company  will  require  additional  financing to fund the
proposed  Superior   acquisition  and  a  line  of  credit  to  fund  Superior's
operations.  There can be no  assurance  that the Company will be able to secure
such  financing or line of credit or that such  financing or line of credit will
be  available  on  favorable  terms.  If the  Company is unable to  obtain  such
financing  or  line  of  credit,  it  will  be  unable  to  close  the  Superior
acquisition.

    Uncertainties Related to NicErase-SL. Under applicable law, the Company will
not be permitted  to sell  NicErase-SL,  and thus  generate any revenue from its
development of NicErase-SL, unless it obtains the necessary regulatory approvals
from the FDA for the commercial sale of that product.  To obtain such regulatory
approvals,  the Company must demonstrate to the satisfaction of the FDA, through
preclinical studies and clinical trials, that NicErase-SL is safe and effective.
Although  the  results  of the  Company's  pilot  Phase 3 clinical  trials  were
encouraging,  they do not necessarily indicate, and they do not guarantee,  that
the results of the ongoing multi-center Phase 3 clinical trial will be favorable
to the  Company.  Nor do the  results  obtained in the  small-scale  pilot tests
completed  by the Company to date  necessarily  indicate  that the Company  will
ultimately  succeed  in  obtaining  FDA  approval  for  the  commercial  sale of
NicErase-SL.  The results from preclinical studies and early clinical trials may
not be predictive of results that will be obtained in large-scale  testing,  and
there can be no assurance that the Company's  clinical  trials will  demonstrate
sufficient safety and efficacy to obtain the requisite  regulatory  approvals or
will result in marketable  products. A number of companies in the pharmaceutical
industry have suffered  significant  setbacks in advanced clinical trials,  even
after  promising  results in earlier  trials.  If NicErase-SL is not shown to be
safe and effective in either current ongoing, or any future clinical trials, and
if the  Company  is thus  unable to  commercialize  NicErase-SL  it would have a
material  adverse  effect on the  Company's  business,  financial  condition and
results of operations.

    Integration of Able and Superior  Acquisitions.  In August 1996, the Company
acquired  certain  assets of Able,  and in March  1997,  the  Company  signed an
agreement to purchase all of the outstanding shares of Superior. There can be no
assurance  that  the  anticipated  benefits  from the  Able  acquisition  or the
proposed Superior  acquisition will be realized.  Additionally,  there can be no
assurance that the Company will be able to effectively  market the existing Able
products, that it will obtain FDA approval to market additional generic drugs or
that it will be successful in managing the combined operations.  The integration
of Able and Superior  requires  substantial  attention from management,  many of
whom have limited  experience  in  integrating  acquisitions.  The  diversion of
management's  attention,  the  process of  integrating  the  businesses  and any
difficulties  encountered in the transition  process could cause an interruption
of  business,  and  could  have a  material  adverse  effect  on  the  Company's
operations and financial performance.

    Risks Associated with Managing a Changing Business. The Company has begun to
expand its business  focus from being a  development  and  licensing  company to
building  a  diversified  healthcare  company  focused  on the  manufacture  and
distribution  of generic drug products as well as the continued  development  of
therapeutic and diagnostic  products.  In order to achieve this  expansion,  the
Company  must  undergo  substantial   changes  in  its  operations,   which  may
significantly  strain the  Company's  limited  administrative,  operational  and
financial  resources.  The  ability  of the  Company  to  achieve  its  business
objectives  will  depend in large  part on its  ability  to build and expand its
manufacturing  operations  and sales and  marketing  capabilities,  to generally
expand its operational capabilities and its


                                       21


financial and management  information  systems, to develop the management skills
of its  managers  and  supervisors  and to train,  motivate  and manage both its
existing  employees and the  additional  employees  that will be required if the
Company is to expand its  business.  There can be no assurance  that the Company
will succeed in developing all or any of these capabilities,  and any failure to
do so would have a material adverse effect on the Company's business,  financial
condition and results of operations.

    Future  Acquisitions.  Management  may  from  time  to time  consider  other
acquisitions of assets,  businesses or technologies that will enable the Company
to acquire complementary skills and capabilities, offer new products, expand its
customer base or obtain other competitive advantages.  There can be no assurance
that the Company  will be able to  successfully  identify  suitable  acquisition
candidates,  obtain  financing on  satisfactory  terms,  complete  acquisitions,
integrate  acquired  operations into its existing  operations or expand into new
markets.  Acquisitions  may result in potentially  dilutive  issuances of equity
securities, the incurrence of debt and contingent liabilities,  and amortization
expense related to intangible  assets  acquired,  any of which could  materially
adversely affect the Company's business and results of operations. Acquisitions,
including the Company's recent  acquisition of Able and the proposed purchase of
Superior,  involve a number of potential  risks,  including  difficulties in the
assimilation  of the acquired  company's  operations and products,  diversion of
management's resources,  uncertainties  associated with operating in new markets
and working with new employees  and  customers,  and the  potential  loss of the
acquired  company's key employees.  There can also be no assurance that the Able
acquisition, the proposed Superior acquisition and future acquisitions,  if any,
will not have a material adverse effect upon the Company's  business and results
of operations.  Once integrated,  acquired  operations may not achieve levels of
revenues,  profitability  or  productivity  comparable to those  achieved by the
Company's existing operations, or otherwise perform as expected.

    Limited  Manufacturing  Capability and Experience.  The Company's  NicCheck,
MycoDot and MycoAKT products are currently made by licensed  manufacturers.  The
Company intends to enter into licenses,  joint venture and similar collaborative
arrangements  with  third  parties  for the  manufacture  of  other  proprietary
products and proposed products. There are no other such agreements and there can
be no assurance  that the Company will be successful  in securing  manufacturing
agreements  for its products or that such  agreements  will prove to be on terms
favorable  to the Company.  In addition,  the  Company's  dependence  upon third
parties for the manufacture of its products and proposed  products could have an
adverse  effect on the  Company's  profitability  and its ability to deliver its
proposed  products  on a timely and  competitive  basis.  To the extent that the
Company  attempts to manufacture any of its products,  there can be no assurance
that the  Company  will be able to attract  and retain  qualified  manufacturing
personnel, or build or rent manufacturing facilities.

    The Company's  generic  therapeutic  products are  manufactured  at its Able
Laboratories  facility in South  Plainfield,  New  Jersey.  In order to maintain
compliance  with FDA GMP  standards,  the Company will have to make  significant
investments in its infrastructure  and plant facility.  The Company will need to
raise capital to finance these  investments  and there can be no assurance  that
the Company will be able to obtain such financing or that such financing will be
available  on  favorable  terms.  There can be no  assurance  that such  capital
expenditures  and  overhead  costs  will not  have a  material  effect  upon the
Company's ability to achieve  profitability.  There can be no assurance that the
Company will retain the key employees it acquired in the Able acquisition.

    Limited   Commercialization  of  Proprietary   Products.   The  Company  has
commercially introduced and is currently marketing through distributors only two
of its proprietary  products,  yielding  limited revenues from the sale of these
products.  Historically,  substantially  all of the Company's  revenues had been
generated  from  research  and  development  contracts  and  license  fees.  The
Company's ability to achieve profitability will depend on its ability to develop
and introduce  commercially  viable products,  obtain  regulatory  approvals for
these products and either successfully  manufacture,  market and distribute such
products  on  its  own  or  enter  into  collaborative  agreements  for  product
manufacturing,  marketing  and  distribution.  Many  of the  Company's  proposed
therapeutic   and   diagnostic   products  will  require   substantial   further
development,  preclinical and clinical testing, and investment by the Company or
third party  licensees in  manufacturing,  marketing  and sales  infrastructures
prior to their  commercialization.  No assurance can be given that the Company's
development efforts will be successfully  completed,  that regulatory  approvals
will be obtained, or that these products, once introduced,  will be successfully
marketed.


                                       22


    Early  Stage of  Product  Development.  Several  of the  Company's  proposed
products,  including its specialty pharmeceuticals,  OrthoDyn, the breast biopsy
technology being licensed from BioLoc and the bacterial extract for treatment of
infectious diseases, are at an early stage of development.  The Company does not
expect that its early stage products will be available for a significant  number
of years, if at all. The early stage products will require significant  research
and  development,  and  potential  products that appear to be promising at early
stages  of  development  may not  reach  the  market  for a number  of  reasons.
Potential products may be found ineffective or cause harmful side effects during
preclinical  testing or clinical trials,  fail to receive  necessary  regulatory
approvals,  be difficult to manufacture  on a large scale,  be  uneconomical  to
produce,   fail   to   achieve   market   acceptance   or  be   precluded   from
commercialization  by  proprietary  rights  of third  parties.  There  can be no
assurance that the Company's or its collaborative  partners' product development
efforts will be successfully completed,  that required regulatory approvals will
be obtained or that any products,  if introduced,  will be successfully marketed
or achieve customer acceptance.

    Lack of Marketing Experience.  The Company currently does not plan to market
its  proprietary  products  directly  and does not have  adequate  resources  or
expertise to develop a substantial  marketing  organization  and internal  sales
force for these products. Since the Company does not have the financial or other
resources  to  undertake  extensive  direct  marketing  activities,  the Company
intends to enter into  marketing  arrangements  with  third  parties,  including
possible joint venture, license or distribution arrangements.  While the Company
intends to license its products for manufacture  and sale to established  health
care or pharmaceutical companies, it has had very limited success in its efforts
to enter  into  such  agreements  to date.  There can be no  assurance  that the
Company will be able to locate  collaborative  partners or that these  strategic
alliances, if consummated, will prove successful.

    With respect to the Company's generic therapeutic products,  there can be no
assurance  that  present and  potential  customers of Able will  continue  their
recent  buying  patterns  without  regard  to  the  Able  acquisition,  and  any
significant delay or reduction in orders could have a material adverse effect on
the Company's near-term business and results of operations.

    Regulation  by Government  Agencies.  The  Company's  research,  preclinical
development,  clinical  trials,  manufacturing  and  marketing  of its  proposed
products  are  subject  to  extensive   regulation   by  numerous   governmental
authorities  in the United  States  (including  the FDA),  and other  equivalent
foreign regulatory authorities.  The process of obtaining FDA and other required
regulatory  approvals is lengthy and  expensive.  There can be no assurance that
the Company will be able to obtain the necessary  approvals for clinical testing
or for  the  manufacturing  or  marketing  of its  proposed  products.  Further,
additional  governmental  regulation may be  established  which could prevent or
delay regulatory approval of the Company's products.  The regulatory process may
delay for long periods,  and  ultimately  prevent,  marketing of new products or
impose  costly  procedures  that  would have a  material  adverse  effect on the
Company's   business.   Failure  to  comply  with  the   applicable   regulatory
requirements can, among other things, result in fines, suspensions of regulatory
approvals, product recalls, operating restrictions and criminal prosecution.

    The Company's  success in the generic drug market  depends,  in part, on its
ability to obtain FDA  approval  of ANDAs for its new  products,  as well as its
ability to procure a  continuous  supply of raw  materials  and to validate  the
manufacturing  processes  used  to  produce  consistent  test  batches  for  FDA
approval.  Sources for certain  materials  for the  Company's  products  must be
approved by the FDA, and in many instances only one source has been approved. If
raw materials from a specified supplier were to become unavailable,  the Company
would  be  required  to  file  a  supplement  to its  ANDA  and  revalidate  the
manufacturing process using a new supplier's materials. This could cause a delay
of several  months in the  manufacture  of the drug involved and the  consequent
loss of potential revenue and market share. Additionally,  there is often a time
lag, sometimes significant,  between the receipt of ANDA approval and the actual
marketing of the approved product due to this validation process.

    The Able Laboratories facility is subject to plant inspections by the FDA to
determine  compliance with GMP standards.  The Company could be subject to fines
and sanctions  such as the  suspension of  manufacturing  or the seizure of drug
products if it were found to be in non-compliance with GMP standards.


                                       23


    Rapid Technological Advances and Competition. The therapeutic and diagnostic
markets in which the  Company  competes  have  undergone  and can be expected to
continue to undergo rapid and significant  technological advances.  There can be
no assurance that the  technological  developments of others will not render the
Company's   technology  or  products   incorporating   such  technology   either
uneconomical  or obsolete.  The Company  competes  with a number of  specialized
biotechnology  companies  and  major  pharmaceutical  companies.  Most of  these
companies have substantially  greater  financial,  technical and human resources
and research and  development  staffs and facilities,  as well as  substantially
greater  experience  in  conducting   clinical  trials,   obtaining   regulatory
approvals, and manufacturing and marketing products than does the Company. There
can be no assurance  that the  Company's  products or proposed  products will be
able to compete successfully.

    In addition,  with its newly acquired  generic  product line, the Company is
now competing in a new market with  off-patent  drug  manufacturers,  brand-name
pharmaceutical   companies  that  manufacture  off-patent  drugs,  the  original
manufacturers  of brand-name  drugs and  manufacturers  of new drugs that may be
used for the same indications as the Company's  products.  There is no assurance
that the Company will compete  successfully  in this market.  Revenues and gross
profit  derived from generic  pharmaceutical  products  tend to follow a pattern
based on regulatory and competitive factors unique to the generic pharmaceutical
industry.  As patents for brand name  products and related  exclusivity  periods
mandated by regulatory  authorities  expire,  the first generic  manufacturer to
receive regulatory  approval for generic equivalents of such products is usually
able to achieve  relatively  high  revenues and gross  profit.  As other generic
manufacturers  receive regulatory  approvals on competing  products,  prices and
revenues typically decline.  Accordingly, the level of revenues and gross profit
attributable to generic  products  developed and  manufactured by the Company is
dependent,  in part,  on its  ability  to  develop  and  introduce  new  generic
products, the timing of regulatory approval of such products, and the number and
timing of regulatory approvals of competing products.  In addition,  competition
in the United States generic pharmaceutical market continues to intensify as the
pharmaceutical  industry  adjusts to increased  pressures to contain health care
costs.  Brand name  companies are  increasingly  selling their products into the
generic market directly by acquiring or forming strategic alliances with generic
pharmaceutical  companies. No regulatory approvals are required for a brand name
manufacturer  to sell  directly or through a third party to the generic  market,
nor do such manufacturers face any other significant barriers to entry into such
market.  These  competitive  factors may have a material  adverse  effect on the
Company's ability to sell its generic products.

    Dependence on Patents and Proprietary  Technology.  The Company owns certain
patents  and has  applied  for other  patents  relating  to its  technology  and
proposed products.  No assurance can be given,  however,  whether pending patent
applications  will be granted or whether any patents granted will be enforceable
or provide the Company with meaningful  protection from  competitors.  Even if a
competitor  were to infringe the Company's  patents,  the costs of enforcing its
patent rights may be substantial or even prohibitive.  In addition, there can be
no assurance that the Company's  proposed  products will not infringe the patent
rights of others. The Company may be forced to expend  substantial  resources if
the Company is required to defend  against  any such  infringement  claims.  The
Company also may desire or be required to obtain  licenses  from others in order
to further develop, produce and market commercially viable products effectively.
There can be no assurance that such licenses will be obtainable on  commercially
reasonable  terms, if at all, that the patents  underlying such licenses will be
valid  and  enforceable  or  that  the  proprietary  nature  of  the  unpatented
technology  underlying such licenses will remain  proprietary.  The Company also
relies on unpatented proprietary know-how and trade secrets, and employs various
methods  including  confidentiality  agreements  with  employees,   consultants,
manufacturing and marketing  partners to protect its trade secrets and know-how.
However,  such methods may not afford  complete  protection  and there can be no
assurance  that others will not  independently  develop  such trade  secrets and
know-how or obtain access thereto.

    The manufacture and sale of certain  products  developed by the Company will
involve the use of processes,  products or information, the rights to certain of
which are owned by others.  Although  the Company  has  obtained  licenses  with
regard to the use of certain such processes, products and information, there can
be no assurance  that such  licenses  will not be  terminated  or expire  during
critical  periods,  that the Company  will be able to obtain  licenses for other
rights which may be important to it, or, if obtained, that such licenses will be
obtained on  commercially  reasonable  terms. If the Company is unable to obtain
such licenses,  the Company may have to develop


                                       24



alternatives  to  avoid  infringing  patents  of  others,   potentially  causing
increased  costs  and  delays  in  product  development  and  introduction,   or
precluding the Company from  developing,  manufacturing  or selling its proposed
products.  Additionally,  there can be no assurance that the patents  underlying
any licenses will be valid and enforceable. To the extent any products developed
by the  Company  are  based on  licensed  technology,  royalty  payments  on the
licenses will reduce the Company's  gross profit from such product sales and may
render the sales of such products uneconomical.

                          INDEPENDENT AUDITORS' REPORT

The Board of Directors and Stockholders
 DYNAGEN, INC.
 Cambridge, Massachusetts

    We have audited the  accompanying  consolidated  balance  sheets of DynaGen,
Inc. and  subsidiary  as of December 31, 1996 and June 30, 1996 and 1995 and the
related  consolidated  statements of loss,  changes in stockholders'  equity and
cash flows for the six months ended  December 31, 1996 and for each of the years
in the  three-year  period ended June 30,  1996.  These  consolidated  financial
statements   are  the   responsibility   of  the   Company's   management.   Our
responsibility  is  to  express  an  opinion  on  these  consolidated  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 includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the  accounting  principles  used and  significant  estimates  made by
management,  as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

    In our opinion,  the  consolidated  financial  statements  referred to above
present fairly,  in all material  respects,  the financial  position of DynaGen,
Inc. and  subsidiary as of December 31, 1996 and June 30, 1996 and 1995, and the
results  of their  operations  and their  cash  flows for the six  months  ended
December 31, 1996 and for each of the years in the three-year  period ended June
30, 1996 in conformity with generally accepted accounting principles.

    As indicated in Note 1 to the consolidated financial statements, the Company
needs  additional  capital to fund its  operations,  its acquisition of Superior
Pharmaceutical Company and the continued support of its proposed products.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                   SIX MONTHS ENDED DECEMBER 31, 1996 AND 1995
                  AND YEARS ENDED JUNE 30, 1996, 1995 AND 1994
      (INFORMATION FOR THE SIX MONTHS ENDED DECEMBER 31, 1995 IS UNAUDITED)

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

 Business and Basis of Presentation

    The consolidated  financial statements include the accounts of DynaGen, Inc.
(the  "Company")  which is developing and marketing  therapeutic  and diagnostic
products for the human health care market and its wholly-owned subsidiary,  Able
Laboratories,  Inc.  ("Able"),  which is engaged in the  manufacture  of generic
pharmaceuticals.  (See  Note  2.)  All  significant  intercompany  balances  and
transactions have been eliminated in consolidation.

 Future Capital Needs; Uncertainty of Additional Funding

    It is  anticipated  that the Company  will  continue  to expend  significant
amounts of capital to fund its research and development,  clinical  trials,  its
generic pharmaceutical  business and the proposed acquisition of Superior.  (See
Note 14.) The Company's  available  working capital is inadequate for completion
of  the  Company's  development  programs,  and  additional  financing  will  be
necessary  for the  continued  support of the  Company's  proposed  products and
operations,   including  the  establishment  of  manufacturing,   marketing  and
distribution capabilities for its proposed products. The Company plans to secure
financing  for the Superior  acquisition  through the sale of equity and/or debt
securities.  In addition, the Company plans to obtain lines of credit, equipment
notes or leases from  financial  institutions  to support the operations of both
Superior and Able.  There can be no  assurance  that the Company will be able to
secure  additional  financing  or  that  such  financing  will be  available  on
favorable  terms. If the Company is unable to obtain such additional  financing,
the  Company's  ability to maintain  its current  level of  operations  would be
materially and adversely affected and the Company will be required to reduce its
overall  expenditures  including  its research  and  development  activity  with
respect to certain proposed products.

 Change in Year End

On January 30, 1997, the Company adopted December 31 as its fiscal year end. The
accompanying   consolidated   financial  statements  include  audited  financial
statements for the six month transition period ended December 31, 1996.  Audited
financial  statements  are also  presented for the three fiscal years ended June
30, 1996, 1995 and 1994.  Unaudited  financial  statements and the related notes
thereto are presented for the six months ended December 31, 1995 for comparative
purposes only. All adjustments, consisting of only normal recurring adjustments,
which in the opinion of management are necessary for a fair  presentation of the
unaudited financial information, have been made.

 Use of Estimates

    In preparing  consolidated financial statements in conformity with generally
accepted  accounting  principles,  management is required to make  estimates and
assumptions that affect the reported amounts of assets and liabilities as of the
balance  sheet date and reported  amounts of revenues  and  expenses  during the
reporting period. Actual results could differ from those estimates.

 Cash Equivalents

    Cash equivalents include interest-bearing  deposits with original maturities
of three months or less.

 Investment Securities

    Effective June 30, 1994, the Company  adopted the provisions of Statement of
Financial  Accounting  Standards  ("SFAS")  No.  115,  "Accounting  for  Certain
Investments  in Debt and Equity  Securities."  Accordingly,  investments in debt
securities  that  management  has the  positive  intent  and  ability to hold to
maturity are classified as "held to maturity" and
carried at amortized cost. Investments that are

                  AND YEARS ENDED JUNE 30, 1996, 1995 AND 1994

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES -- (Continued)

purchased and held  principally for the purpose of selling them in the near term
are  classified  as  "trading  securities"  and  carried  at  fair  value,  with
unrealized gains and losses included in earnings.  Investments not classified as
either of the above are  classified as "available  for sale" and carried at fair
value,  with  unrealized  gains and losses  reported as a separate  component of
stockholders'  equity.  The  cumulative  effect  of  the  change  in  accounting
principle  at June 30,  1994 was to  decrease  stockholders'  equity by $38,662.
There was no effect on the net loss for the year ended June 30, 1994.

    Prior to June 30, 1994, investment securities were carried at amortized cost
which  approximated  fair value.  Gains and losses on  disposition of investment
securities are computed by the specific identification method.

 Inventory

Inventory  is valued at the  lower of cost or  market  on a  first-in  first-out
(FIFO) method.

 Property and Equipment

    Property and equipment are stated at cost.  Depreciation expense is provided
over the estimated  useful lives of the assets using the  straight-line  method.
Leasehold  improvements  are  amortized  on the  straight-line  method  over the
shorter of the  estimated  useful  life of the asset or the life of the  related
lease term.

 Goodwill, Organization Expenses, Patents, Trademarks and Deferred Debt
Financing Costs

    Goodwill and organization expenses were amortized over a five-year period on
a straight-line  basis and were fully amortized as of June 30, 1994.  Patent and
trademark costs are amortized over a five-year  period on a straight-line  basis
commencing  on the  earlier of the date placed in service or the date the patent
or trademark is granted.  Deferred debt financing costs are being amortized on a
straight-line basis over the two-year term of the convertible note payable.  The
related amortization expense for the six months ended December 31, 1996 and 1995
was $73,107 and  $10,792,  respectively,  and for the years ended June 30, 1996,
1995 and 1994 was $79,660, $11,385 and $21,388, respectively.

 Deferred Offering Costs

    Deferred  offering costs represent costs incurred in connection with raising
capital.  Upon  completion  of an offering,  the amount  credited to  additional
paid-in capital is reduced by the deferred offering costs.

 Revenue Recognition

    Revenues  from  product  sales are  recognized  when  products  are shipped.
Revenues  from license fees and  royalties  are  recognized  as the terms of the
agreements are met.  Revenues  earned under  long-term  contracts are recognized
using the  percentage-of-completion  method.  Anticipated  losses on uncompleted
contracts are charged to operations when incurred.

 Income Taxes

    Deferred tax assets and liabilities  are recorded for temporary  differences
between the financial  statement and tax bases of assets and  liabilities  using
the currently  enacted  income tax rates expected to be in effect when the taxes
are actually  paid or  recovered.  A deferred tax asset is also recorded for net
operating loss,  capital loss and tax credit  carryforwards  to the extent their
realization  is more likely than not.  The  deferred  tax expense for the period
represents  the change in the deferred tax asset or liability from the beginning
to the end of the period.

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES -- (Continued)

Stock-Based Compensation

    In October 1995, the Financial  Accounting  Standards  Board ("FASB") issued
SFAS  No.  123,  "Accounting  for  Stock-Based   Compensation."  This  Statement
encourages  all  entities to adopt a fair value based method of  accounting  for
employee stock compensation plans,  whereby compensation cost is measured at the
grant date based on the value of the award and is  recognized  over the  service
period,  which is usually the vesting period.  However, it also allows an entity
to continue  to measure  compensation  cost for those plans using the  intrinsic
value based method of accounting  prescribed by APB Opinion No. 25,  "Accounting
for Stock Issued to Employees," whereby compensation cost is the excess, if any,
of the quoted market price of the stock at the grant date (or other  measurement
date) over the amount an employee  must pay to acquire the stock.  Stock options
issued under the Company's  stock option plans generally have no intrinsic value
at the grant date, and under Opinion No. 25 no  compensation  cost is recognized
for them.  The Company has elected to remain with the  accounting in Opinion No.
25 and, as a result,  must make pro forma disclosures of net income and earnings
per share and other disclosures, as if the fair value based method of accounting
had been applied.  The disclosure  requirements  of this Statement are effective
for the Company's  consolidated  financial  statements  for the six months ended
December 31, 1996. The pro forma  disclosures  include the effects of all awards
granted on or after July 1, 1995. (See Note 10.)

 Net Loss Per Share

    Net loss per share is  calculated  based on the weighted  average  number of
common  shares  outstanding  during the year.  The  effect of all  common  stock
equivalents has been excluded from the calculation  since its inclusion would be
anti-dilutive.

 New Accounting Pronouncements

    The FASB issued SFAS No. 121,  "Accounting  for the Impairment of Long-Lived
Assets and for Long-Lived  Assets to Be Disposed Of" in March 1995. SFAS No. 121
requires the Company to review for  impairment  of  long-lived  assets,  certain
identifiable intangibles and goodwill related to those assets whenever events or
changes in  circumstances  indicate that the carrying amount of an asset may not
be recoverable.  In certain situations,  an impairment loss would be recognized.
SFAS No. 121 is effective for the six months ended December 31, 1996. The impact
of adoption of the new  standard  was not  material to the  Company's  financial
position, results of operations and cash flows.

    The FASB issued SFAS No. 128,  "Earnings per Share," in February 1997.  SFAS
No. 128 establishes  standards for computing and presenting  earnings per share,
and is  effective  for  financial  statements  issued for periods  ending  after
December 15, 1997, earlier  application is not permitted.  SFAS No. 128 requires
the restatement of all prior period earnings per share data presented.

2. ACQUISITION OF ABLE LABORATORIES, INC.

    On August 19, 1996, the Company  acquired  certain assets of Able consisting
primarily  of  machinery  and  equipment,   raw  materials  and  finished  goods
inventory,  and other assets of the tablet business. The assets were transferred
by the  Company  to a  newly  formed  and  wholly-owned  subsidiary  named  Able
Laboratories,  Inc.  The  purchase  price  consisted  of  $550,000  in cash  and
acquisition  costs of $150,000.  The  acquisition  has been  accounted  for as a
purchase in  accordance  with  Accounting  Principles  Board Opinion No. 16. The
Company  allocated  $313,300 of the purchase  price to inventory and $386,700 to
property  and  equipment.  The results of  operations  related to Able have been
included with those of the Company since August 19, 1996.

1,  1993.  There was no  provision  for income  taxes for the six  months  ended
December 31, 1996 and 1995 and for the years ended June 30, 1996,  1995 and 1994
due to the Company's net operating losses.  The difference between the statutory
Federal income tax rate of 34% and the Company's effective tax rate is primarily
due to net operating  losses  incurred by the Company and the valuation  reserve
against the Company's deferred tax asset.

    The components of the net deferred tax asset are as follows:

purchase 20,000 shares of common stock at a price of $5.25 per share exercisable
through January 15, 1999.

    On November 20, 1995, the Company entered into a one-year investment banking
agreement  with the  underwriter  of the Company's  prior public  offerings.  As
compensation  for services,  the Company  granted a warrant to purchase  400,000
shares of common stock at an exercise  price of $2.50 per share.  The warrant is
exercisable  through  November 20, 2000. The shares  underlying the warrant were
registered on a Form S-3 registration  statement declared effective on March 29,
1996. In September 1996, the Company and the underwriter  amended the agreement,
and the Company paid the  underwriter  $500,000 in consulting  fees for services
rendered.

    On July 24, 1996,  the Company's  Board of Directors  granted  non-qualified
stock  options to two  directors  of the  Company to purchase  an  aggregate  of

exercise  price of $1.31 per share.  This option is  exercisable by the director
until  October 28,  2003.  The  weighted  average  fair value of these  options,
estimated using the Black-Scholes option-pricing model, on the date of grant was
$1.20 per share.

    On December 10, 1996, the Company granted  warrants to purchase an aggregate
of 100,000 shares of common stock at an exercise price of $1.44 per share. These
warrants are  exercisable  through  December 31,  2003.  The Company  valued the
warrants at $99,000 and is expensing  the warrants  over their  vesting  period.
Expense for the six months ended December 31, 1996 was $19,800.

 Stock-Based Compensation

    At December 31, 1996, the Company has two stock-based compensation plans and
stock  options  issued  outside of the plans,  which are  described  above.  The
Company applies APB Opinion No. 25 and related Interpretations in accounting for
stock options issued to employees and directors. Had

    Common stock  equivalents  have been excluded from all  calculations  of net
loss per share because the effect of including them would be anti-dilutive.

    The fair value of each option  grant under the 1991 Plan is estimated on the
date of grant using the  Black-Scholes  option-pricing  model with the following
weighted  average  assumptions  used for  grants  during  the six  months  ended
December 31, 1996 and the year ended June 30, 1996, respectively; dividend yield
of 0%; risk-free interest rates of 6.5% and 6.4%; expected volatility of 80% and
80% and expected lives of 3.8 and 3.9 years.

14. SUBSEQUENT EVENTS

    On January 13, 1997,  $1,065,000  of the  convertible  note (see Note 6) was
exchanged for 989,594 shares of common stock of the Company.

    On January  15,  1997 the Company  granted  warrants  to a public  relations
consultant  to purchase  50,000  shares of common stock at an exercise  price of
$1.97. These warrants are exercisable through January 15, 2002.

    On January 30, 1997, the stockholders  approved an increase in the number of
authorized  shares of common stock from  40,000,000  to 75,000,000  shares.  The
stockholders  also voted to amend the 1991 Stock Plan to increase  the number of
shares of common stock  authorized  for issuance  thereunder  from  1,200,000 to
2,600,000 shares.

    On March 7, 1997, the Company entered into an agreement to acquire the stock
of Superior Pharmaceutical Company ("Superior") of Cincinnati, Ohio. Superior, a
privately-held company,  markets and distributes generic pharmaceutical products
to independent,  retail chain and  institutional  pharmacies.  Superior reported
1996 sales of $32 million with pre-tax income of over $3.0 million.

    Under the terms of the agreement, DynaGen will pay Superior's shareholders a
total of $16.5  million,  consisting  of $6.5  million in cash to be paid at the
closing,  $5 million in three-year  notes and 1,666,666 shares of DynaGen common
stock.  The agreement  provides that the aggregate  value of the DynaGen  common
stock to be issued is to be equal to  $5,000,000.  If at the first  twelve-month
anniversary  of the  closing,  the value of the common stock issued is less than
$5,000,000,  then DynaGen shall deliver to the selling  stockholders  additional
shares  (and cash,  if average  closing bid price is less than $1.50) to satisfy
the deficiency.  The  shareholders may also receive certain  incentive  payments
based on Superior's  performance  during the three years  following the close of
the  transaction.  The successful  completion of the  transaction is subject to,
among  other  closing  conditions,   obtaining   satisfactory  equity  and  debt
financing.

15. FAIR VALUE OF FINANCIAL INSTRUMENTS

    At December 31, 1996 and June 30, 1996, the Company's financial  instruments
include  investment  securities  which are  carried  at fair value (see Note 3),
notes  receivable (see Note 8) and a convertible  note payable (see Note 6). The
carrying  value of the notes  receivable  approximate  their fair value as these
instruments  bear  interest and mature in less than one year.  The fair value of
the  outstanding  balance  of the  convertible  note  payable  is  approximately
$2,786,000 and $2,985,000 at December 31, 1996 and June 30, 1996,  respectively,
based on the fair value of the common stock issuable on conversion of the note.

    To  provide  scientific   guidance  to  the  Company's  product  development
programs,  as well as assistance in recruiting employees and collaborators,  the

consulting  agreements  typically  specify  the  compensation  to be paid to the
consultant  and require that all  information  about the Company's  products and
technology  be  kept  confidential.  Most of the  consultants  are  employed  by
employers  other than the Company and may have  commitments  to or consulting or
advisory agreements with other entities that may limit their availability to the
Company.  The consultants have agreed,  however,  not to provide any services to
any other  entities that might  conflict with the services that they provide the
Company.  Members of the Company's  Scientific Advisory Board offer consultation
on specific issues encountered by the Company.

                          AGREEMENT AND PLAN OF MERGER


         Agreement  and  Plan  of  Merger  dated  as  of  March  7,  1997  (this
"AGREEMENT")  by and among  DynaGen,  Inc., a Delaware  corporation  ("PARENT");
DynaGen  Acquisition  Corp., a Delaware  corporation and a direct,  wholly-owned
subsidiary  of  Parent  ("SUB");   Superior   Pharmaceutical  Company,  an  Ohio
corporation (the "COMPANY");  and Eric C.  Hagerstrand  ("HAGERSTRAND"),  Dennis
Smith ("SMITH") and Thomas Canning ("CANNING"), the stockholders of the Company.
Each of Hagerstrand,  Smith and Canning are hereinafter collectively referred to
as the "STOCKHOLDERS".

                                   WITNESSETH:

         WHEREAS,  the  respective  Boards of Directors  of Parent,  Sub and the
Company have each  determined  that it is advisable and in the best interests of
each company and its respective stockholders for Parent to enter into a business
combination  with the Company upon the terms and subject to the  conditions  set
forth herein; and

         WHEREAS,  in furtherance of such combination,  the respective Boards of
Directors  of Parent,  Sub and the Company  have each  approved  the merger (THE
"MERGER")  of Sub with and into the Company in  accordance  with the  applicable
provisions of the General  Corporation  Law of the State of Delaware  ("DELAWARE

conditions set forth herein.

         NOW,  THEREFORE,  in  consideration of the foregoing and the respective
representations,   warranties,  covenants  and  agreements  set  forth  in  this
Agreement, the parties hereto agree as follows:

                                    ARTICLE I

         SECTION 1.1. THE MERGER.  Upon the terms and subject to the  conditions
set forth in this  Agreement,  and in accordance with Delaware Law and Ohio Law,
at the Effective  Time (as defined in Section 1.2), Sub shall be merged with and

shall be Superior Pharmaceutical Company.

         SECTION 1.2.  EFFECTIVE TIME.  Unless this Agreement shall have earlier

pursuant to Section 9.1 hereof,  the closing of the Merger (the  "CLOSING") will
take place as  promptly as  practicable  (and in any event  within two  business
days) after the  satisfaction  or, if permissible,  waiver of the conditions set
forth in Article  VIII hereof,  at the offices of Taft,  Stettinius & Hollister,
1800 Star Bank Center, 425 Walnut Street, Cincinnati, Ohio 45202, unless another
date, time or place is agreed to in writing by the parties hereto. The date upon
which the Closing  occurs is herein  referred to as the  "CLOSING  DATE." On the
Closing Date,  the parties  hereto shall cause the Merger to be  consummated  by
filing a certificate of merger (the  "CERTIFICATE OF MERGER") with the Secretary
of State of the State of  Delaware  and the  Secretary  of State of the State of
Ohio,  in such form as required by Delaware  Law and Ohio Law (the date and time
of such filings being the "EFFECTIVE TIME").

discretion.  Effective  as of the Closing,  Hagerstrand  and Smith shall also be

right, title and possession to all assets, property, rights, privileges,  powers
and franchises of the Company and Sub, the officers and directors of the Company
and Sub immediately prior to the Effective Time are fully authorized in the name
of their  respective  corporations or otherwise to take, and will take, all such

                                   ARTICLE II

               CONVERSION OF SECURITIES; EXCHANGE OF CERTIFICATES

         SECTION 2.1.  DEFINITIONS.

                  "COMPANY  COMMON  STOCK" shall mean the Common  Stock,  no par
value, of the Company.

                  "MERGER CONSIDERATION" shall mean (i) $6,500,000 in cash, (ii)
Notes in the aggregate principal amount of $5,000,000 and (iii) 1,666,667 shares
of Parent Common Stock.

                  "OUTSTANDING SHARES" shall mean the aggregate number of shares
of Company Common Stock outstanding immediately prior to the Effective Time.

                  "PARENT  COMMON STOCK" shall mean the Common Stock,  par value
$.01 per share, of Parent.

         SECTION  2.2.  MERGER  CONSIDERATION;  CONVERSION  OR  CANCELLATION  OF
COMPANY  COMMON STOCK.  (a) At the  Effective  Time, by virtue of the Merger and
without any action on the part of Parent, Sub, the Company or the holders of any
shares  of  Company  Common  Stock,  each of the  Outstanding  Shares  shall  be
converted   into  the  right  to  receive  a  pro  rata  amount  of  the  Merger
Consideration, based on each Stockholder's equity interest in the Company.

                  (b) If between the date of this  Agreement  and the  Effective
Time, the outstanding shares of Parent Common Stock shall have been changed into
a different number of shares or a different class by reason of a stock dividend,
subdivision,  reclassification,  recapitalization,  split-up or combination, the
number of shares of Parent  Common  Stock  included in the Merger  Consideration
shall be appropriately adjusted.

                  (c) At the Effective  Time, each share of Company Common Stock
issued and outstanding and owned by Parent or any of its subsidiaries (including
Sub) or held in the treasury of the Company  immediately  prior to the Effective
Time  shall,  by virtue of the Merger and  without any action on the part of the
holder thereof, cease to be outstanding, be canceled and retired without payment
of any consideration therefor and cease to exist.

                  (d) At the Effective Time, each share of Sub Common Stock, par
value $.01 per share, issued and outstanding  immediately prior to the Effective
Time shall  thereupon be converted into and become one (1) share of Common Stock
of the Surviving Corporation.

         SECTION 2.3. EXCHANGE OF CERTIFICATES. (a) Prior to the Effective Time,
Parent will appoint its transfer agent (the "Exchange  Agent") to effectuate the
delivery of the consideration  provided for in Section 2.2 to holders of Company

Effective  Time  represented  all  Outstanding  Shares of Company  Common  Stock
("Certificates").






                     Agreement and Plan of Merger - Page 4


                  (b) Upon surrender of a Certificate to the Exchange Agent, the
holder of such Certificate shall be entitled to receive in exchange therefor the
Merger  Consideration  provided for in Section  2.2(a),  and the  Certificate so
surrendered shall forthwith be canceled.

                  (c)  Subject  to  Sections   2.4,  2.5  and  2.6,  all  Merger
Consideration  issued upon  conversion of the shares of Company  Common Stock in
accordance  with the terms  hereof  shall be deemed to have been  issued in full
satisfaction of all rights pertaining to such shares of Company Common Stock.

                  (d) Neither Parent, Sub nor the Company shall be liable to any
holder of shares of Company Common Stock for any Merger Consideration  delivered
to a public official pursuant to any abandoned property, escheat or similar law.
From and after the Effective Time, and until  surrendered in accordance with the
provisions  of Section 2.3, each  Certificate  representing  Outstanding  Shares
shall  represent,  for all  purposes,  only the  right  to  receive  the  Merger
Consideration.

                  (e) Parent shall be entitled to deduct and  withhold  from the
consideration  otherwise payable to any holder of shares of Company Common Stock
such  amounts as Parent is required to deduct and  withhold  with respect to the
making of any such payment  under the Internal  Revenue Code of 1986, as amended
(the "CODE"), or any provision of state, local or foreign tax law. To the extent
that amounts are so withheld by Parent,  such withheld  amounts shall be treated
for all  purposes  of this  Agreement  as having  been paid to the holder of the
shares  of  Company  Common  Stock  in  respect  of  which  such  deduction  and
withholding was made by Parent.

          SECTION 2.4 TANGIBLE NET WORTH REQUIREMENT

                  (a) As of the Closing  Date,  the Company  shall have Tangible
Net  Worth (as  defined  in this  Section  2.4) of at least  $2,750,000.  If the
Tangible Net Worth of the Company as set forth on the balance sheet contained in
the Closing  Financial  Statements (as defined in this Section 2.4) is less than
$2,750,000  as of the Closing  Date,  Parent  shall  withhold the amount of such
shortfall,  pro rata from the Stockholders,  from the first payment of principal
under the Notes.  If the  Tangible  Net Worth of the Company as set forth on the
balance  sheet  contained in the Closing  Financial  Statements  is greater than
$2,750,000 as of the Closing Date,  Parent shall  distribute  the amount of such
excess,  pro rata among the  Stockholders,  at the time of the first  payment of
principal under the Notes.

                  (b) For purposes  hereof,  the term "Tangible Net Worth" shall
mean the net worth of the Company as determined in the audited balance sheets of
the Company as of December 31, 1996 (under the caption "Stockholders'  Equity"),
as adjusted for transactions  through the Closing Date, in all cases of the type
which would be set forth on a balance  sheet of the Company in  accordance  with
generally accepted accounting principles consistently applied.

                  (c) As promptly as  practicable  after the Closing Date but in
no event later than  forty-five (45) days  thereafter,  Parent shall oversee and
cause  to be  prepared  by the  Company's  auditors  (Grant  Thornton  LLP)  and
delivered to Parent and the Stockholders a reviewed balance sheet of the Company
as at the close of  business  on the Closing  Date and a reviewed  statement  of
earnings and cash flows from January 1, 1997 to the Closing Date,  together with
the  review  report of the  Company's  auditors,  addressed  to  Parent  and the
Stockholders,  stating that its review of the Closing  Financial  Statements was
made in  accordance  with  statements  on standards  for  accounting  and review
services issued by the American Institute of Certified Public  Accountants.  The
reviewed  Closing  Statements  will be presented in  accordance  with  generally
accepted accounting  principles and applied on a basis consistent with such U.S.
generally  








                     Agreement and Plan of Merger - Page 5


accepted accounting  principles and the financial  statements of the Company for
the fiscal  years  December  31, 1994,  1995 and 1996,  previously  furnished to
Parent. Such financial statements, as so reviewed, are referred to herein as the
"Closing  Financial  Statements." The cost of such review and the preparation of
the Closing  Financial  Statements by the Company's  auditors  shall be borne by
Parent.

                  (d) The  calculation  of  Tangible  Net Worth set forth in the
balance sheet contained in the Closing  Financial  Statements shall be deemed to
be  conclusive  and binding  upon the  parties,  unless at or prior to the fifth
business day following the  completion of the Closing  Financial  Statements and
their delivery to Parent and the Stockholders,  Parent or the Stockholders shall
give written notice to the other that it objects to the valuation,  inclusion or
omission of any item.  Such notice shall specify  Parent's or the  Stockholders'
objections  to the  computation  of  Tangible  Net  Worth,  citing  the items or
principles disputed. In the event that Parent and the Stockholders are unable to
mutually  agree upon the  valuation or amount of any disputed  item set forth in
such  notice  within  twenty  (20)  days  after  the  receipt   thereof  by  the
non-objecting   party,   the  parties  shall  submit  the  unresolved  items  to
arbitration by a firm of independent  public  accountants to be selected jointly
by Parent and the  Stockholders.  Such  accounting  firm shall be  requested  to
consider the respective positions of the parties and render an opinion as to the
valuation or amount of the disputed  items.  The  determination  of such jointly
selected  accounting  firm shall be  conclusive  and  binding  upon the  parties
hereto.  The cost of such  accounting  firm shall be paid by the  non-prevailing
party. A party shall be deemed to have prevailed with regard to disputed matters
if its last offer or demand  immediately  prior to submission to such accounting
firm is closer to the final  resolution  of the disputed  matters than the other
party's offer or demand.

         SECTION  2.5.ADDITIONAL  CONSIDERATION.  If at the  first  twelve-month
anniversary of the Closing, the average closing bid price of Parent Common Stock
for the ten (10) trading days immediately  preceding such anniversary (the "FAIR
MARKET  VALUE")  multiplied by the  aggregate  number of shares of Parent Common
Stock  delivered  at the  Closing  equals an amount  less than  $5,000,000  (the
"DEFICIENCY"),  then Parent,  within  forty-five  (45) days of such  anniversary
shall deliver to the  Stockholders,  pro rata based on the  Outstanding  Shares,
that number of shares of Parent Common Stock equal to the Deficiency  divided by
the Fair Market  Value,  if the Fair Market Value is a trading price equal to or
greater  than $1.50 per share of DynaGen  Common  Stock.  To the extent the Fair
Market Value is less than $1.50 per share of DynaGen Common Stock,  Parent shall
also pay to the  Stockholders  in immediately  available funds the extent of the
additional  Deficiency below the $1.50 trading price. By way of illustration and
example:  (a) if the  Fair  Market  Value as  determined  above  is  $2.00,  the
aggregate  number of shares of DynaGen  Common  Stock to be issued  shall be the
product  obtained by dividing the  Deficiency  of  $1,666,666  [$5,000,000  less
1,666,667 x $2.00 (FMV) = $5,000,000 less $3,333,334 = $1,666,666 of Deficiency]
by the Fair Market Value of $2.00 ($1,666,666  (184) $2.00 = 833,333  additional
shares of DynaGen Common Stock); under such example,  Parent shall issue 833,333
additional shares of DynaGen Common Stock.

         (b) If the Fair Market Value is under $1.50 per share of DynaGen Common
Stock,  Parent  will  then  issue  (in the  aggregate  to all  Stockholders)  an
additional 1,666,667 shares of DynaGen Common Stock. The remaining amount of the
Deficiency, calculated following the issuance of the additional 1,666,667 shares
of DynaGen Common Stock,  shall be an amount equal to $5,000,000  less 3,333,334
shares of  DynaGen  Common  Stock  multiplied  by the Fair  Market  Value.  Such
remaining   Deficiency  amount  shall  be  then  paid  to  the  Stockholders  in
immediately available funds.

         The shares of Parent  Common Stock which may be issued  pursuant to the
foregoing provisions are referred to as the "ADJUSTMENT SHARES."






                     Agreement and Plan of Merger - Page 6


         SECTION 2.6. INCENTIVE  PAYMENTS.  (a) Subject to Section 2.6(b) below,
if the Surviving Corporation achieves Net Sales (as defined below) for the years
ending  December 31,  1997,  1998 and 1999 equal to or greater than $32 million,
$35 million, and $39 million respectively (the "NET SALES TARGETS"), then Parent
or the Surviving  Corporation shall pay to the  Stockholders,  pro rata based on
the Outstanding  Shares,  an aggregate of $550,000 for each such year that these
Net Sales Targets have been achieved ("TARGET PAYMENTS"). Any such payment shall
be  paid  to  the  Stockholders  within  forty-five  (45)  days  after  Parent's
independent  accountants  have  issued  their  report  on the  Parent's  audited
financial  statements  for such  period.  "NET SALES" means the net sales of the
Surviving   Corporation   determined  in  accordance  with  generally   accepted
accounting  principles  ("GAAP")  applied  on  the  basis  consistent  with  the
Company's  audited  statements of earnings for the year ended  December 31, 1996
attached hereto as part of Schedule 3.7.

                  (b) Upon a Change in Control (as  hereinafter  defined)  which
occurs prior to December 31, 1999, the Target Payments and all unpaid  principal
and interest on the Notes shall, immediately prior to consummation of the Change
in Control,  accelerate and become fully vested and payable to the Stockholders;
provided,  however,  that the  Parent  or  Surviving  Corporation  shall  not be
required to pay any Target  Payment with respect to any year which was completed
prior to the  Change in  Control  and for which the Net Sales  Targets  were not
achieved.  For  purposes of the  foregoing,  "CHANGE IN CONTROL"  shall mean the
acquisition  of the  Parent  or the  Surviving  Corporation  by  (i)  the  sale,
issuance,  exchange or transfer,  in a single transaction or a series of related
transactions,  of greater than fifty  percent (50%) of the  outstanding  capital
stock of the Parent or the Surviving  Corporation to a third party in connection
with any business combination or other acquisition and in which such third party
has the right to elect,  and does  elect,  a majority of the  Parent's  Board of
Directors, (ii) the sale of all or substantially all of the assets of the Parent
or the Surviving Corporation to a third party, or (iii) a merger,  consolidation
or other  reorganization  involving the Parent and one or more other entities in
which the shares of the Parent's or Surviving Corporation's  outstanding capital
stock immediately prior to such transaction are converted into, exchanged for or
represent less than a majority of the voting power of the surviving or resulting
entity.

         (c) In the  event any of  Hagerstrand  or Smith is  terminated  without
"cause"  under  such  Stockholder's  Employment  Agreement  (as  defined  in the
Stockholder's Employment Agreement), then the Target Payments shall, immediately
upon such  termination,  accelerate  and become  fully vested and payable to all
Stockholders;  provided, however, that the Parent or Surviving Corporation shall
not be required  to pay any Target  Payment  with  respect to any year which was
completed  prior to the date of termination  and for which the Net Sales Targets
were not achieved.  In the event of any  termination of Hagerstrand or Smith for
cause (as defined in such Stockholder's Employment Agreement),  such Stockholder
shall  continue  to be  entitled  to  receive  his pro rata  share of any Target
Payment  otherwise  payable in the  absence of any such  termination;  provided,
however,  that the Parent or Surviving  Corporation shall not be required to pay
any Target  Payment  with respect to any year which was  completed  prior to the
date of  termination  and for which the Net Sales Targets were not achieved.  In
the event of any voluntary  termination of employment by any  Stockholder,  such
Stockholder shall not receive his pro rata share of any Target Payment otherwise
payable in the absence of any such termination.

         SECTION  2.7.  NO  FRACTIONAL  SHARES.  No  certificates  or scrip  for
fractional  shares of Parent Common Stock will be issued,  no Parent stock split
or  dividend  shall  relate  to any  fractional  share  interest,  and  no  such
fractional  share  interest  shall  entitle the owner  thereof to vote or to any
rights of or as a  stockholder  of  Parent.  In lieu of such  fractional  shares
(after  taking into account all shares of Company  Common Stock then held by any
such holder), any holder of Company Common Stock who







                     Agreement and Plan of Merger - Page 7


would  otherwise be entitled to a fraction of a share of Parent Common Stock (or
any other Person who is the record holder of  certificates  for shares of Parent
Common Stock into which such shares of Company Common Stock have been converted)
will, upon surrender of his Certificate or Certificates,  be paid the cash value
of such fraction (without interest and rounded to the nearest cent), which shall
be equal to the fraction multiplied by the closing bid price per share of Parent
Common Stock on the day preceding the Closing.

         SECTION  2.8.CHECKS OR CERTIFICATES IN OTHER NAMES. If any check or any
certificate  evidencing  shares of Parent Common Stock is to be issued in a name
other than that in which the  Certificate  surrendered in exchange  therefore is
registered, it shall be a condition of the issuance thereof that the Certificate
so  surrendered  shall be properly  endorsed  and  otherwise  in proper form for
transfer  and  that  the  Person  requesting  such  exchange  establish  to  the
satisfaction  of the Exchange  Agent or of Parent acting solely in its corporate
capacity,  as the case may be,  that any  transfer  or other  taxes  required by
reason of the issuance of a check or a  certificate  for shares of Parent Common
Stock in any name other than that of the  registered  holder of the  Certificate
surrendered or otherwise required has been paid or is not payable.

         SECTION 2.9. DISTRIBUTIONS WITH RESPECT TO UNEXCHANGED SHARES OF PARENT
COMMON  STOCK.  No dividends or other  distributions  declared or made after the
Effective  Time with respect to Parent Common Stock with a record date after the
Effective Time shall be paid to the holder of any unsurrendered Certificate with
respect to the shares of Parent  Common Stock  evidenced  thereby,  and no other
part of the Merger  Consideration  shall be paid to any such  holder,  until the
holder of such  Certificate  shall  surrender such  Certificate.  Subject to the
effect of applicable laws,  following  surrender of any such Certificate,  there
shall be paid to the  holder  of the  certificates  evidencing  whole  shares of
Parent Common Stock issued in exchange therefor, without interest, (i) promptly,
the amount of any cash  payable  with  respect to a  fractional  share of Parent
Common  Stock to which such holder is  entitled  pursuant to Section 2.7 and the
amount  of  dividends  or other  distributions  with a  record  date  after  the
Effective  Time  theretofore  paid with  respect to such whole  shares of Parent
Common Stock, and (ii) at the appropriate  payment date, the amount of dividends
or other distributions, with a record date after the Effective Time but prior to
surrender and a payment date occurring after surrender,  payable with respect to
such whole share of Parent Common Stock.

         SECTION 2.10.  STOCK TRANSFER  BOOKS.  At the Effective Time, the stock
transfer  books of the  Company  shall be closed  and there  shall be no further
registration  of transfers of shares of Company  Common Stock  thereafter on the
records of the Company or the Surviving Company. On or after the Effective Time,
any Certificates  presented to the Exchange Agent or Parent for any reason shall
be converted into the Merger Consideration.

         SECTION 2.11. LOST, STOLEN OR DESTROYED CERTIFICATES.  In the event any
Certificates shall have been lost, stolen or destroyed, the Exchange Agent shall
make payment in exchange for such lost, stolen or destroyed  Certificates,  upon
the making of an affidavit of that fact by the holder thereof,  for the pro rata
amount of the Merger Consideration;  provided,  however, that Parent may, in its
discretion  and as a condition  precedent to the issuance  thereof,  require the
owner of any such lost, stolen or destroyed  Certificate or Certificates  having
an  aggregate  value of $100,000 or more to deliver a bond in such sum as Parent
may  reasonably  direct as indemnity  against any claim that may be made against
Parent or the Exchange  Agent with respect to the  Certificates  alleged to have
been lost, stolen or destroyed.

position of the Company for the periods  then ended.  Except as may be set forth
in the  Financial  Statements,  all of the  revenues and expenses of the Company
reflected in the Financial  Statements  were derived or incurred in the ordinary
course of business of the Company.  The account records underlying the Financial
Statements  accurately  and  fairly  reflect,  in  reasonable  detail and in all
material respects,  the transactions of the Company,  and the Company's books of
account have been  maintained  in  accordance  with GAAP applied on a consistent
basis.  All accounts,  notes and other  receivables of the Company are valid and
enforceable,  are not subject to any valid  defense,  set off,  counterclaim  or
claim for returns or refunds,  and are  collectible  in full in accordance  with
their terms in the  ordinary  course of business of the  Company,  except to the
extent of any reserves  therefor  reflected on the Balance Sheet or taken in the
ordinary  course  of  business  consistent  with  past  practice  which,  in the
aggregate, are not materially adverse to the Company.

         SECTION 3.8. ABSENCE OF UNDISCLOSED LIABILITIES.  To the best knowledge
of  the  Company  and  the  Stockholders,  the  Company  has no  liabilities  or
obligations  which are, or reasonably could be expected to be, in the aggregate,

condition of the Company,  except those liabilities or obligations which are (a)
fully  reflected  or  adequately  reserved  against in the  Balance  Sheet,  (b)
disclosed  in this  Agreement or in Schedule 3.8 or (c) incurred in the ordinary
course of business  consistent  with past practice  since December 31, 1996 (the

"LIABILITIES OR OBLIGATIONS" shall include any direct or indirect  indebtedness,
claim, loss, damage, deficiency (including deferred income tax and other net tax

secured or unsecured.

         SECTION 3.9.  TITLE AND CONDITION OF ASSETS.  The assets and properties
owned,  leased or subleased by the Company  constitute,  and on the Closing Date
will  constitute,  all of the assets and properties  used or held for use in the
conduct of the  business of the  Company,  and are, and on the Closing Date will
be,  generally  adequate  to conduct the  business  of the Company as  currently
conducted.  The  Company  has,  and on the  Closing  Date will have  record  and
marketable  title to, or valid  leasehold  interests  in,  all of its assets and

                           wrongful  termination  law may  limit  the  Company's
                           ability to terminate  such  agreements,  contracts or
                           commitments;

                           will be  increased,  or the  vesting of  benefits  of
                           which will be  accelerated,  by the occurrence of any
                           of the transactions contemplated by this Agreement or
                           the  value of any of the  benefits  of which  will be
                           calculated  on the  basis of any of the  transactions
                           contemplated by this Agreement;

                           engage in any line of  business  or compete  with any
                           Person;

                           in any  corporation,  partnership,  joint  venture or
                           other business enterprise;






                     Agreement and Plan of Merger - Page 14


                  (xii)    any   mortgages,    indentures,   loans   or   credit
                           agreements,  security  agreements or other agreements
                           or instruments  relating to the borrowing of money or
                           extension of credit, including guaranties referred to
                           in clause (viii) hereof;

                  (xiii)   any  purchase  order or contract  for the purchase of
                           raw  materials  or  acquisition  of assets  involving
                           $50,000 or more;

                  (xiv)    any   distribution,   joint   marketing,   supply  or
                           development agreement; or

                  (xv)     any other  agreement,  contract or  commitment  which
                           involves  payment  by the  Company of $25,000 or more
                           and is not cancelable  without  penalty within thirty
                           (30) days.

        The Company has not breached, or received in writing any claim or threat
that it has breached,  any of the terms or  conditions  of any other  agreement,
contract  or  commitment  in such a manner as would  permit  any other  party to
cancel or  terminate  the same or would  permit any other party to seek  damages
from the Company that could  reasonably  be expected to have a Material  Adverse
Effect. Each agreement, contract or commitment set forth in any of the Company's
schedules is in full force and effect and, except as otherwise disclosed in such
schedule,  to the  knowledge  of the  Company  and the  Stockholders,  each such
agreement,  contract  or  commitment  is not  subject  to any  material  default
thereunder by any party obligated to the Company pursuant  thereto.  The Company
has  obtained,  or will  obtain  prior  to the  Effective  Time,  all  necessary
consents,  waivers and approvals as are required in  connection  with the Merger
under any of the Company's material agreements.

                (b) There is no contract, agreement, commitment or obligation to
which the Company is a party or is bound that,  at the time it was entered  into
or made was, or is currently,  known or expected by the Company to result in any
material loss to the Company upon completion or performance thereof, or any bid,
offer or proposal which, if accepted would result in such a contract, agreement,
commitment or obligation.

                (c) Except as disclosed in Schedule  3.14,  the Company is not a
party to any agreement with any of its securityholders or optionholders,  or any
affiliate thereof, nor, to the knowledge of the Company,  without inquiry by the
Company,  is any  securityholder  or  optionholder of the Company a party to any
agreement with any other such  securityholder  or  optionholder  relating to the
Company or any of its securities.

        SECTION  3.15.  EMPLOYEES.  Schedule 3.15 sets forth a true and complete
list of (a) the names,  titles,  annual  salaries and other  compensation of all
employees  of the  Company  (the  "EMPLOYEES")  and the  location  at which such
Employees  regularly perform services for the Company and (b) the wage rates for
non-salaried  Employees  of the Company  (by  classification).  Any  agreements,
commitments or  understandings  between the Company and any Employee  concerning
such Employee's future salary, compensation or terms of employment are described
in Schedule 3.15.  Except as set forth on Schedule 3.15,  none of such Employees
has  indicated  to the  Company  that he or she intends to resign or retire as a
result of the  transactions  contemplated  by this  Agreement or otherwise.  The
Company  is  in  compliance  with  all  currently   applicable  laws  respecting
employment  and  employment  practices,  terms and  conditions of employment and
wages and hours,  and is not engaged in any unfair  labor  practice,  failure to
comply with which or engagement in which,  as the case may be, has had, or could
reasonably be expected to have, a Material Adverse Effect on the Company.  There
is no unfair  labor  practice 







                     Agreement and Plan of Merger - Page 15


complaint  pending or, to the knowledge of the Company,  threatened  against the
Company before the National Labor Relations Board.

         SECTION  3.16.  TRANSACTIONS  WITH  AFFILIATES.  Except as set forth in
Schedule 3.16,  since January 1, 1993,  there have been and are no agreements or
other  continuing  transactions  between the Company,  on the one hand,  and any
affiliate of the Company,  any of the stockholders of the Company, any affiliate
of any  stockholder  of the  Company,  or any  member of any such  stockholder's
family,  on the  other  hand.  Except  as set  forth in  Schedule  3.16,  to the
knowledge of the  Company,  none of the officers or directors of the Company (a)
has any material  direct or indirect  interest in any entity which does business
with the Company or any  property,  asset or right which is used by the Company;
or (b) has any contractual relationship with the Company.

         SECTION 3.17. INSURANCE COVERAGE. The Company has furnished to Parent a
list of, and true and complete  copies of, all  insurance  policies and fidelity
bonds  covering  the  assets,  business,  equipment,   properties,   operations,
employees,  officers and directors of the Company  (including without limitation
any policies pertaining to product liability).  There is no claim by the Company
pending  under  any of such  policies  or bonds as to  which  coverage  has been
questioned,  denied or disputed by the  underwriters  of such policies or bonds.
All premiums  payable  under all such  policies and bonds have been paid and the
Company is otherwise in compliance  in all material  respects with the terms and
conditions of all such policies and bonds.  Such policies of insurance and bonds
(or other policies and bonds providing substantially similar insurance coverage)
have been in effect since January 1, 1995 and remain in full force and effect.

         SECTION 3.18.  COMPLIANCE WITH LAWS. The Company is not in violation of
any applicable provisions of any law, statute, ordinance,  regulation, judgment,
order, injunction,  permit, license, certificate or other authorization,  or its
governing  instruments,  except for  violations  that have not had and could not
reasonably be expected to have a Material Adverse Effect on the Company.

         SECTION 3.19. ACCOUNTS RECEIVABLE; INVENTORIES. (a) Except as set forth
on Schedule  3.19(a),  the accounts  receivable  of the Company,  including  the
accounts  receivable  reflected  on the Balance  Sheet and  accounts  receivable
acquired by the Company between the Balance Sheet Date and the Closing Date, are
valid and existing and represent bona fide claims against  debtors for sales and
other  charges,  and were  acquired in the ordinary  course of business and have
been  collected,  or are  expected to be  collected  in the  ordinary  course of
business within a period not exceeding 90 days from invoice date, in full and in
accordance  with their  terms at their  recorded  amounts,  subject  only to the
reserve for  receivables  as  reflected  on the face of the Balance  Sheet,  and
(subject to the aforesaid reserves) are subject to no refunds, discounts (except
for normal cash and immaterial trade discounts) or other adjustments and, to the
best knowledge of the Company, to no defenses, rights of setoff,  counterclaims,
encumbrances or conditions  affecting any thereof.  The accounts receivable have
been  accrued on the books of the  Company in the  ordinary  course of  business
consistent  with past practices in accordance with GAAP, and the amount reserved
for doubtful  accounts and allowances  disclosed in the Balance Sheet or accrued
on such books is consistent with past practices.

              (b) Schedule  3.19(b) sets forth a detailed  list of all inventory
of the Company.  All of the inventories  that are reflected in Schedule  3.19(b)
(i) were purchased or acquired in the ordinary course of the Company's  business
and in a manner consistent with the regular inventory  practices of the Company,
(ii) have been or will be used or sold in the ordinary course of business and in
a manner  consistent  with its  regular  inventory  practices,  (iii) are not in
excess  of the  Company's  reasonable  requirements,  and  (iv)  are or  will be
reflected  in  the  Company's  financial  statements  in  accordance  with  GAAP

                     Agreement and Plan of Merger - Page 16


applied.  Since the Balance  Sheet Date,  due provision was made on the books of
the Company in the ordinary course of business consistent with past practices to
provide for all slow-moving, obsolete or unusable inventories to their estimated
useful or scrap values and such  inventory  reserves are adequate to provide for
such slow-moving, obsolete or unusable inventory and inventory shrinkage.

              (c) Except as disclosed on Schedule  3.19(b),  the inventory  does
not consist of any damaged or obsolete inventory or inventory not fit for use in
the ordinary course of business,  including without limitation (i) raw materials
or  work-in-process  that are not used in current  formulations of the Company's
products,  (ii) any raw  materials  or  work-in-process  that,  according to the
production schedule of the business, would not reasonably be expected to be used
within six months  after the Closing  Date or, if  earlier,  the end of such raw
material's  or  work-in-process'  useful  life,  (iii) any  finished  goods that
represent  products  returned prior to November 1, 1996, (iv) any finished goods
for which no sales are forecast in the  Company's  sales plan,  (v) any finished
goods not salable in the ordinary course of business at the Company's  published
prices without  additional  manufacturing  or packaging  cost, (vi) any finished
goods  that are  "remnant",  and (vii)  any raw  materials,  work-in-process  or
finished  goods that, as a result of any judgment,  order,  decree or settlement
relating to product  labeling or otherwise,  may not be used in current  product
formulation.  All  inventory has been stored,  shipped and otherwise  handled in
compliance in all material  respects with all applicable  federal and state law,
rules and regulations  (including,  without  limitation those promulgated by the
U.S. Food and Drug Administration ("FDA")).

         SECTION 3.20.  FINDERS' FEES.  There is no investment  banker,  broker,
finder or other  intermediary  that has been retained by or is authorized to act
on behalf of the Company who might be  entitled  to any fee or  commission  from
Parent or any of its subsidiaries or the Company upon consummation of the Merger
and the transactions contemplated by the Operative Documents.

         SECTION 3.21.  EMPLOYEE BENEFIT PLANS.  Except as set forth in Schedule
3.21 neither the Company nor any Person that  together with the Company would be
treated  as a  single  employer  under  Section  414  of  the  Code  (an  "ERISA
AFFILIATE") has  established or maintains or is obligated to make  contributions
to or under or otherwise participate in (a) any bonus or other type of incentive
compensation  plan,  program,   agreement,   policy,  commitment,   contract  or
arrangement  (whether or not set forth in a written document),  (b) any pension,
profit-sharing,  retirement or other plan,  program or  arrangement,  or (c) any
other employee  benefit plan,  fund or program,  including,  but not limited to,
those described in Section 3(3) of the Employment Retirement Income Security Act
of 1974,  as  amended  ("ERISA").  All such  plans  (individually,  a "PLAN" and
collectively,  the "PLANS") have been operated and  administered in all material
respects in accordance with, as applicable, ERISA, and the Code, and the related
rules and  regulations  adopted by those federal  agencies  responsible  for the
administration  of  such  laws.  No act or  failure  to act by the  Company  has
resulted in, nor does the Company have  knowledge of a "prohibited  transaction"
(as  defined  in ERISA)  with  respect  to the Plans  that is not  subject  to a
statutory or regulatory  exception.  No "reportable event" (as defined in ERISA)
has  occurred  with  respect to any of the Plans which is subject to Title IV of
ERISA.  At the Effective  Time,  the fair market value of the assets of any Plan
which is  subject  to Title IV of ERISA will  exceed  the  present  value of all
benefits  accrued under such Title IV Plan,  determined  on a termination  basis
using assumptions  established by the Pension Benefit Guaranty  Commission as in
effect on that date. Neither the Company nor any ERISA Affiliate has (i) engaged
in, or is a successor or parent  corporation to an entity that has engaged in, a
transaction  described in Section 4069 of ERISA, or (ii) incurred, or reasonably
expects to incur prior to the Effective  Time,  any liability  under Title IV of
ERISA  arising in  connection  with the  termination  of, or complete or partial
withdrawal  from,  any Plan covered or  previously  covered by Title IV or ERISA
that  could  become a  liability  of the  Parent  or Sub or any of  their  ERISA
Affiliates after the 






                     Agreement and Plan of Merger - Page 17


Effective  Time. The Company has not previously  made, is not currently  making,
and is not obligated in any way to make, any contributions to any multi-employer
plan within the meaning of the  Multi-Employer  Pension Plan  Amendments  Act of
1980.

         SECTION  3.22.  TAXES.  (a) The term  "TAXES" as used herein  means all
federal,  state,  local,  foreign  and other net  income,  gross  income,  gross
receipts, sales, use, ad valorem, transfer,  franchise, profits, license, lease,
service,  service use,  withholding,  payroll,  employment,  excise,  severance,
stamp, occupation, premium, property, windfall profits, customs duties, or other
taxes,  fees,  assessments or other charges of any kind whatever,  together with
any interest and any  penalties,  additions  to tax or  additional  amounts with
respect  thereto.  The  term  "Returns"  as  used  herein,  means  all  returns,
declarations,  reports,  statements and other documents  required to be filed in
respect of Taxes,  and  "RETURN"  means any one of the  foregoing  returns.  All
citations to the Code, or the Treasury regulations promulgated thereunder, shall
include any amendments or any substitute or successor provisions thereto.

                  (b) The Company has filed all Returns required to be filed and
has  paid  all  Taxes  owed  (whether  or not  shown  as due on  such  Returns),
including,  without  limitation,  all Taxes  which the Company is  obligated  to
withhold for amounts owing to employees,  creditors and third parties.  All such
Returns  were  complete  and correct in all  material  respects.  All Taxes with
respect to which the Company has become  obligated  have been paid and  adequate
reserves  have  been  established  for all  Taxes  accrued  but not yet  payable
(including  any  Taxes  arising  out of the  transactions  contemplated  by this
Agreement). To the knowledge of the Company and the Stockholders, no issues have
been raised (and are  currently  pending) by any taxing  authority in connection
with any of the Returns.  No waivers of statutes of  limitation  with respect to
any of the  Returns  have  been  given by or  requested  from the  Company.  All
deficiencies  asserted or assessments made as a result of any examinations  have
been  fully  paid,  or are  fully  reflected  as a  liability  in the  financial
statements  of the  Company,  or are being  contested  and an  adequate  reserve
therefor has been established and is fully reflected in the financial statements
of the Company.  There are no liens for Taxes (other than for current  Taxes not
yet due and payable) upon the assets of the Company. All material elections with
respect to Taxes affecting the Company,  as of the date hereof, are set forth in
the financial statements of the Company, or are annexed hereto in Schedule 3.22.
The Company is not a party to any agreement,  contract, arrangement or plan that
has resulted or would result, separately or in the aggregate, (i) in the payment
of any "excess  parachute  payments"  within the meaning of Section  280G of the
Code (without  regard to the exception in Sections  280G(b)(4) and 280G(b)(5) of
the Code) or (ii) in any payment  which would not be deductible  under  Sections
162 and 404 of the Code. The Company has not agreed to make any adjustment under
Section 481(a) of the Code (or any similar  provision of law or  regulations) by
reason of a change in accounting  method or otherwise,  and the Company will not
be  required to make any such  adjustment  as a result of the  transactions  set
forth in this  Agreement.  The Company does not have and has not had a permanent
establishment in any foreign country, as defined in any applicable Tax treaty or
convention  between the United States of America and such foreign  country.  The
Company  does not own any  interest in any entity  which is  characterized  as a
partnership  for  federal,  state,  local,  foreign or other Tax  purposes.  The
Company  is not  and  has  not  been  a  United  States  real  property  holding
corporation during the applicable period specified in Section  897(c)(1)(A)(ii).
The  Company  has not  participated  in or  cooperated  with  any  international
boycott, within the meaning of Section 999 of the Code.

                  (c) Set forth on  Schedule  3.22 is a  complete  and  accurate
description  of the Company's (i) tax basis in its assets,  (ii) tax  elections,
(iii) methods of accounting, and (iv) agreements with respect to Taxes.





                     Agreement and Plan of Merger - Page 18


                  (d) The Company has never filed a consent  pursuant to Section
341(f) of the Code,  relating to collapsible  corporations.  The Company and its
stockholders  made (i) a valid  election  for the Company to be treated as an "S
corporation",  as that term is defined in Section 1361(a) of the Code and (ii) a
similar  valid  election  under  the  laws of the  State  of  Ohio or any  other
applicable governmental  authority,  and all of such elections will be in effect
at the Effective  Time. An election  under Section  1362(a) of the Code (and any
similar  election  under the laws of the  State of Ohio or any other  applicable
Governmental  Authority) has been in effect with respect to the Company (and any
predecessor  corporation)  for each of its taxable  years (within the meaning of
Section 1374(c) of the Code).  Schedule 3.22 lists each such election and a true
copy of each such  election  is attached  thereto;  there are no grounds for the
revocation   of  any  such  election  and  no  such  election  will  be  revoked
retroactively or otherwise except at the Effective Time by reason of the Merger.
The Company has not taken any action that would  cause,  or would result in, the
termination of the S corporation  status of the Company,  other than pursuant to
this Agreement.  Each of the Stockholders hereby individually represents that he
has not taken any action that has caused,  would cause,  or would result in, the
termination of the S Corporation status of the Company prior to the date hereof,
other than pursuant to this  Agreement.  Neither the Company nor any predecessor
has  ever  (i)  been a  party  to  any  merger  or  consolidation  nor  acquired
substantially  all  of the  assets  of  any  Person,  (ii)  adopted  a  plan  of
liquidation,  or (iii) made any election  under  Section 936 or 992 of the Code.
There will be no tax imposed by Section  1374 of the Code and any  corresponding
provisions of the laws of the State of Ohio or any other applicable Governmental
Authority in connection with the Merger.

                  (e) Each of the Stockholders  hereby  individually  represents
that he has timely filed all Returns  with respect to Taxes  required to be paid
by a Stockholder  attributable to items of income, gain, deductions,  losses and
credits of the Company, and has timely paid all such Taxes (whether or not shown
on such  Returns);  there  has not been any  audit of any  Return  filed by such
Stockholder,  or to the Company's  knowledge,  any previous  shareholder  of the
Company,  with  respect  to, or which may  relate  to,  items of  income,  gain,
deduction,  loss or credit of the Company; no such audit of any such Stockholder
is in progress and such  Stockholder  has not been notified by any  Governmental
Authority that any such audit is contemplated or pending.

                  (f)  In the  event  that  it is  determined,  either  (i) by a
finding  or order  in  connection  with  any  government  or  judicial  audit or
proceeding to which the Company or the  Stockholders  are a party or (ii) by the
Company's  independent  accountants,  that the Company's S election  pursuant to
Section 1362 of the Code (or any  corresponding  election  under the laws of the
State of Ohio or any other applicable governmental authority) was not validly in
effect for any  period  after  such  election  was  purportedly  made,  then the
Stockholders  of the Company shall  promptly  remit to the Company in cash,  any
foreign,  federal,  state and/or local Tax liability  (including  any penalties,
additions to Tax or interest  assessed  with respect  thereto) of the Company in
connection  with any Taxes  which may be imposed  on the  Company as a result of
such  invalid  election.  To the extent  Tax  deductions  or losses,  which were

      SECTION 3.27.  STOCKHOLDER  REPRESENTATIONS.  (a) Each Stockholder  hereby
individually  represents  and  warrants  that  (i) it is his  original,  present
intention  to acquire the Parent  Common  Stock for his own account and that the
Parent  Common Stock is being and will be acquired for the purpose of investment
and not with a view to  distribution or resale except as provided  herein;  (ii)
due to his business and financial  experience  and his status as an  "accredited
investor"  under  Regulation D of the  Securities  Act of 1933,  as amended (the
"SECURITIES ACT"), each Stockholder has the ability to protect his own interests
in  connection  with  the  transactions  contemplated  hereby  and is  generally
familiar with the business,  operations  and financial  condition of the Parent,
and (iii) he  understands  that the shares of Parent Common Stock being acquired
hereunder may only be resold in  compliance  with  applicable  federal and state
securities laws, including Rule 144 of the Securities Act.

              (b) Each  Stockholder  individually  understands  and agrees that,
until  registered  under  the  Securities  Act or  transferred  pursuant  to the
provisions of Rule 144 as promulgated by the Securities and Exchange Commission,
the Parent Common Stock issuable pursuant to this Agreement shall bear a legend,
prominently stamped or printed thereon, reading substantially as follows:

         "The  securities   represented  by  this   certificate  have  not  been
         registered  under the Securities  Act of 1933 and any applicable  state
         securities laws. These securities have been acquired for investment and
         not with a view to distribution or resale.  These securities may not be
         offered for sale,  sold,  delivered  after sale or  transferred  in the
         absence of an effective registration statement covering such securities
         under  the  Act  and  any  applicable  state  securities  laws,  or the
         availability,  in the opinion of counsel reasonably satisfactory to the
         Company, of an exemption from registration thereunder."

              (c) Each Stockholder,  in his individual capacity,  has had access
to  information  relative to the Parent's  business,  financial  condition,  and
results of operations  prior to the purchase of the Parent  Common  Stock.  Each
Stockholder,  in his individual  capacity,  has such knowledge and experience in
financial and business  matters that he is capable of evaluating  the merits and
risks of the acquisition of the Parent Common Stock.  Each  Stockholder,  in his
individual  capacity,  can bear the economic  risks of this  investment  and can
afford a complete loss of this investment.

              (d) Each  Stockholder,  in his  individual  capacity,  understands
that: the Parent Common Stock has not been  registered  under the Securities Act
and applicable state securities  laws, and,  therefore,  cannot be resold unless
they are  subsequently  registered under the Securities Act and applicable state
securities laws or unless an exemption from such registration is available;  and
no state  or  governmental  authority  has made  any  finding  or  determination
relating to the fairness of the terms of the  acquisition  of the Parent  Common
Stock. Each  Stockholder,  in his individual  capacity,  agrees not to resell or
otherwise  dispose of all or any part of the Parent  Common  Stock  purchased by
such Stockholder, except as permitted by law, including, without limitation, any
regulations  under the Securities Act and applicable







                     Agreement and Plan of Merger - Page 21


state  securities  laws.  Each  Stockholder,  in his individual  capacity,  also
understands  that any routine  sales of the Parent Common Stock in reliance upon
Rule 144 under the Act, if the  provisions  of Rule 144 should then be available
as to the  Parent  Common  Stock,  can be made  only  after the  holding  period
specified in Rule 144, in limited amounts,  and in accordance with all the terms
and conditions of Rule 144.

              (e) Each Stockholder hereby  individually  represents and warrants
that he has no present need for liquidity in connection with the purchase of the
Parent  Common  Stock.  The  acquisition  of the  Parent  Common  Stock  by each
Stockholder  is  consistent  with  the  general  investment  objectives  of each
Stockholder.  Each Stockholder hereby individually  represents and warrants that
he  understands  that the purchase of the Parent  Common  Stock  involves a high
degree of risk.

      SECTION  3.28.  TITLE.   Except  as  set  forth  on  Schedule  3.28,  each
Stockholder  hereby  individually  represents  and warrants  that he is the sole
record and beneficial owner of, and has good, valid and marketable title to, the
shares of Company  Common Stock to be sold by him, free and clear of any and all
liens, security interests, pledges,  encumbrances,  claims, equities, defects in
title, rights and other restrictions of any nature on transfer or voting held by
any third party  (collectively  "ENCUMBRANCES").  Each Stockholder  individually
represents and warrants that the performance by him of his obligations hereunder
will be effective to transfer good,  valid and marketable title to the shares to
be sold by him hereunder, free and clear of any and all Encumbrances, other than
those that may be imposed under federal or state  securities  laws, and that the
consummation of the transactions herein contemplated will not result in a breach
or default  of the terms and  provisions  of any  stockholder  agreement,  stock
pledge,  guaranty,  loan or other agreement to which the Stockholder is a party,
or  of  any  order,  rule  or  regulation  of  any  court,  regulation  body  or
administrative agency applicable to the Stockholder.

lease or operate its  properties  and assets and to carry on its business as now
being conducted.  Each of Parent and Sub is duly qualified to do business and is
in good standing in each jurisdiction  where the character of the property owned
or  leased  by it or the  nature  of its  activities  makes  such  qualification
necessary, other than in such jurisdictions where the failure to be so qualified
would not,  individually or in the aggregate,  have a Material Adverse Effect on
Parent. Each of Parent and Sub has heretofore made available to the Company true
and complete copies its Certificate of Incorporation and By-Laws,  as amended to
date and as currently in effect.

         SECTION  4.2.  CORPORATE  AUTHORIZATION.  The  execution,  delivery and
performance by Parent and Sub of this  Agreement and the Operative  Documents to

Documents  are within the  corporate  power and  authority of Parent and Sub and
have  been  duly  authorized  by all  necessary  corporate  action.  Each of the
Operative Documents has been duly authorized,  executed and delivered by each of
Parent  and Sub (to the  extent a party  thereto)

Common Stock to be issued in the Merger and filings with the NASD and the Nasdaq
SmallCap  Market in connection with listing the shares of Parent Common Stock to
be issued in the Merger on the Nasdaq SmallCap Market, and (iii) such filings or
notifications  which  would  not  prevent  or delay  consummation  of any of the

material respect.

         SECTION 4.4. NON-CONTRAVENTION. The execution, delivery and performance
by Parent and Sub of this Agreement and the Operative Documents (to the extent a

violation of any provision of any law, rule, regulation,  judgment,  injunction,
order or decree  currently in effect and binding upon or applicable to Parent or
any of its subsidiaries or any of their respective properties, (iii) require any
consent,  approval or other action by any Person, contravene or conflict with or
constitute  a  violation  of or a  default  under,  or give rise to any right of
termination,  cancellation  or acceleration of any right or obligation of Parent
or any of its subsidiaries or to a loss of any benefit to which Parent or any of
its subsidiaries is entitled,  under any material provision of (A) any agreement
binding upon Parent or any of its subsidiaries,  or (B) assuming compliance with

         SECTION  4.5.  CAPITALIZATION.  (a) (i) As of  January  31,  1997,  the
authorized  capital  stock of  Parent  consisted  of (i)  10,000,000  shares  of

or other proceeding  pending or, to the knowledge of Parent,  threatened against
or  relating  to Parent or any of its  subsidiaries  or any of their  respective

may be, and the rules and  regulations of the SEC thereunder  applicable to such
Parent  SEC  Documents,  and  none of the  Parent  SEC  Documents,  as of  their
respective  dates,  contained any untrue statement of a material fact or omitted

                                    ARTICLE V

                            COVENANTS OF ALL PARTIES

         Each of the parties  hereto hereby  covenants and agrees with the other
parties as follows:

         SECTION  5.1.  COOPERATION.  It shall  cooperate  fully  with the other
parties hereto in furnishing any information or performing any action reasonably
requested  by any such party,  which  information  or action is necessary to the
speedy and successful  consummation  of the  transactions  contemplated  by this
Agreement or is necessary, appropriate or desirable for the respective corporate
purposes of Parent, Sub and the Company.

         SECTION 5.2. OTHER REQUIRED INFORMATION.  It shall furnish to the other
parties hereto any  application  or statement,  and all  information  concerning
itself and its  Affiliates as is required to be set forth in any  application or
statement to be filed with any  Governmental  Authority in  connection  with the
transactions contemplated by this Agreement.  "AFFILIATE" means, with respect to
a specified Person, any Person that directly,  or indirectly through one or more
intermediaries, controls, is controlled by, or is under common control with, the
Person specified.

         SECTION  5.3.  CONFIDENTIALITY.  (a) All  information  furnished by one
party (the  "DISCLOSING  PARTY") to any other party (the  "RECEIVING  PARTY") in
connection with this Agreement and the Operative  Documents and the transactions
contemplated  hereby and thereby  shall be kept  confidential  by the  receiving
party (and shall be used by it only in  connection  with this  Agreement and the
transactions  







                     Agreement and Plan of Merger - Page 25


contemplated  hereby),  except to the  extent  that such  information  (i) is or
becomes  generally  available  to the public  other than as a direct or indirect
result of disclosure by the receiving party (or any of its directors,  officers,
employees,  agents, advisors or Affiliates (the "AGENTS")),  (ii) was within the
possession of the receiving  party prior to its being furnished to the receiving
party by or on behalf of the disclosing  party (provided that the source of such
information is not known by the receiving party to be bound by a confidentiality
agreement  with  or  other  contractual,   legal  or  fiduciary   obligation  of
confidentiality to the disclosing party or any other Person with respect to such
information),   (iii)   becomes   available   to  the   receiving   party  on  a
non-confidential  basis from a source other than the disclosing  party or any of
its Agents  (provided that such source is not known by the receiving party to be
bound  by a  confidentiality  agreement  with or  other  contractual,  legal  or
fiduciary  obligation of  confidentiality  to the disclosing  party or any other
Person with respect to such information), or (iv) is required to be disclosed in
any document filed with the SEC or any other Governmental Authority.

                  (b) If the  receiving  party or any of its Agents is requested
or required (by oral  questions,  interrogatories,  requests for  information or
documents in legal proceedings,  subpoena,  civil investigative  demand or other
similar process) to disclose any of the confidential information,  the receiving
party  shall use all  reasonable  efforts to provide the  disclosing  party with
prompt  written notice of any such request or requirement so that the disclosing
party may seek a  protective  order or other  appropriate  remedy  and/or  waive
compliance  with the  provisions  of this  Agreement.  If, in the  absence  of a
protective  order or other  remedy or the receipt of a waiver by the  disclosing
party,  the receiving party or any of its Agents are  nonetheless,  based on the
advice of counsel, required to disclose confidential information to any tribunal
or else stand  liable for  contempt  or suffer  other  censure or  penalty,  the
receiving party or its Agents may, without liability hereunder, disclose to such
tribunal only that portion of the  confidential  information  which such counsel
advises the receiving party is legally  required to be disclosed.  The receiving
party shall  exercise its best efforts to preserve  the  confidentiality  of the
confidential information,  including by cooperating with the disclosing party to
obtain  an  appropriate  protective  order  or  other  reliable  assurance  that
confidential  treatment  will be accorded the  confidential  information by such
tribunal.

                  (c) If the  transactions  contemplated by this Agreement shall
fail to be  consummated,  the receiving party shall promptly cause all copies of
documents  or  extracts  thereof  containing  information  and  data  as to  the
disclosing party to be returned to the disclosing party.

         SECTION 5.4. PUBLIC ANNOUNCEMENTS. Parent and Sub, on the one hand, and
the Company, on the other hand, will consult with each other before issuing, and
provide each other the opportunity to review and comment upon, any press release
or other public statements with respect to the transactions contemplated by this
Agreement,  and shall not issue any such press  release or make any such  public
statement  prior to such  consultation,  except upon the advice of counsel  that
such a release is required by or is appropriate  under applicable law, policy or
regulation of the SEC, court process or by  obligations  pursuant to any listing
agreement with any national securities exchange or national securities quotation
system.

terms and  conditions  provided  in this  Agreement,  each  party  shall use all
reasonable  efforts to take,  or cause to be taken,  all  action,  and to do, or
cause  to  be  done,  all  things  necessary,  appropriate  or  desirable  under
applicable laws and regulations to consummate the  transactions  contemplated by
this Agreement. Each party shall, and shall cause each of its Affiliates to, use

Governmental   Authorities   necessary,   appropriate   or  desirable   for  the
consummation of the transactions contemplated by this Agreement.






                     Agreement and Plan of Merger - Page 26


         SECTION 5.6. BOARD REPRESENTATION.  Effective as of the Closing, Parent
shall appoint to Parent's  board of directors one (1)  individual  designated by
the Stockholders and reasonably acceptable to Parent to hold office for one year
or until the next annual meeting of stockholders of Parent. Any appointments for
a  succeeding  term  for  the  designee  of the  Stockholders  shall  be made in
accordance with Parent's By-Laws.

         SECTION 5.7. BEST EFFORTS AND FURTHER  ASSURANCES.  Each of the parties
to this  Agreement  shall use its best efforts to  effectuate  the  transactions
contemplated  hereby and to fulfill and cause to be fulfilled the  conditions to
closing under this Agreement.  Each party hereto,  at the reasonable  request of
another party hereto,  shall execute and deliver such other  instruments  and do
and perform  such other acts and things as may be  necessary  or  desirable  for
effecting  completely the  consummation  of this Agreement and the  transactions
contemplated  hereby.  Subject to its further rights under this Agreement,  each
party  shall use all  reasonable  efforts  to cause the  Closing to occur at the
earliest practicable time.

         SECTION 5.8. OPERATIONS FOLLOWING CLOSING.  From and after the Closing,
Parent agrees to establish a separate working capital account for the benefit of
the  operations  of the Surviving  Corporation.  Such account will be managed by
Dennis  Smith  and Eric  Hagerstrand;  provided  such  individuals  will  inform
Parent's  management of the status of such working  capital account as requested
from time to time by Parent.  All cash flow from the operations of the Surviving
Corporation  will be used to finance the continuing  operations of the Surviving
Corporation,  including accounts  receivable,  accounts payable and payroll. Any
capital   expenditures  and  extraordinary   expenses  (excluding  purchases  of
inventory)  not already  budgeted for or approved by the board of the  Surviving
Corporation  shall require the prior written consent of the Parent,  which shall
not be unreasonably  withheld or delayed.  At the end of each calendar  quarter,
and subject in all  instances to  compliance at all times with the financial and
other required  covenants of any holder of indebtedness  for borrowed money, and
the prior payment of principal and interest on such indebtedness,  the Surviving
Corporation shall pay to the Stockholders all required payments of principal and
interest on the Notes then payable to the  Stockholders.  To the extent there is
surplus cash flow from operations  following  payment of all required  principal
and interest on outstanding indebtedness (including the Notes), the surplus cash
flow from operations shall, at Parent's option, be transferred to Parent. To the
extent there is any working  capital  deficit,  including any deficit  regarding
payments of  outstanding  indebtedness  for borrowed  money and the Notes of the
Stockholders,  Parent shall advance funds to the Surviving Corporation from time
to time necessary to fund such working capital deficit.


         SECTION 5.9.  GUARANTIES OF THE COMPANY.  The parties  hereto shall use
their best efforts to obtain  terminations,  signed by the respective lender, of
the Company's guaranties,  other than in connection with the Credit Facility, in
favor of The Huntington  National Bank and Hamilton County Development Co., Inc.
In addition,  the parties  shall use their best efforts to obtain  amendments to
the 504 Loan Documents (as defined in Schedule 3.3 to this Agreement) which will
provide  that the  Surviving  Corporation  shall have no  liability  to Hamilton
County  Development  Co.,  Inc.  as a result of such loan.  If the  parties  are
unsuccessful in obtaining such  terminations  and amendments,  the  Stockholders
shall cause SPC Properties  Limited ("SPC") to enter into an amendment as of the
Closing (the "Lease Amendment") to the Commercial Lease Agreement dated March 9,
1995 (the "Lease") regarding the payment of the Surviving  Corporation's monthly
rental  obligation.  The  Lease  Amendment  shall  provide  that  the  Surviving
Corporation  shall pay  directly to the  mortgagees  of the leased  property the
Surviving  Corporation's rental obligation.  To the extent the rental obligation
exceeds  the  monthly  obligations  of  SPC  to the  mortgagees,  the  Surviving
Corporation  shall pay such excess to SPC.  







                     Agreement and Plan of Merger - Page 27


Notwithstanding  the  foregoing,  SPC must  ensure that by March 31,  2000,  the
Surviving  Corporation shall have no obligation to the Huntington  National Bank
and  Hamilton  County  Development  Co.  in  connection  with  the  loans to SPC
regarding the land associated with the Lease.

instruments  as may be required so that the  transactions  contemplated  by this
Agreement  shall not  result  in any  default  with  respect  to any law,  rule,
regulation, order, decree, license, agreement or commitment to which the Company
is a party or its assets is bound.  Without limiting the foregoing,  the Company
shall  use its  commercially  reasonable  efforts  to assist  Parent  and Sub to
transfer  the  rights and  obligations  of the  Revolving  Line of Credit to the
Surviving  Corporation  and to assist Parent and Sub in securing any replacement
or  additional  line of credit which Parent and Sub believes is required to fund
adequately the business of the Surviving Corporation.

         SECTION 6.4. COMPANY  STOCKHOLDERS  MEETING. The Company shall, as soon

designees  may  reasonably  request.  The  Company  shall  cause its  respective

representatives  to cooperate  with Parent in its due  diligence  investigation.
From the date hereof  until the  Effective  Time,  Parent and the Company  shall

                                   ARTICLE IX

                                   TERMINATION

         SECTION 9.1.  Termination.  This  Agreement may be  terminated  and the
transactions  contemplated  hereby  abandoned at any time prior to the Effective
Time,  whether before or after  approval of the matters  presented in connection
with the Merger by the stockholders of the Company:

                  (a) by written  mutual  consent of Parent and the  Company for
any reason, or by mutual action of their respective Boards of Directors;

                  (b) at the option of Parent,  by written notice from Parent to
the Company if (i) a material  breach by the Company or the  Stockholders of any
of their respective representations,  warranties or agreements contained in this
Agreement  occurs,  (ii)  Parent  has  notified  the  Company  in writing of the
existence of such breach,  and (iii) the Company or the Stockholders have failed
to cure such  breach  within 10 days  after  receiving  such  notice (or if such
breach is not capable of being cured  within such 10 day period,  but is capable
of being cured within 30 days,  the breaching  party shall have  commenced  good
faith steps to promptly cure such breach);

                  (c) at the  option  of the  Company  or the  Stockholders,  by
written notice from the Company to Parent if (i) a material  breach by Parent or
Sub of any of their representations,  warranties or agreements contained in this
Agreement occurs, (ii) the Company has notified Parent and Sub in writing of the
existence  of such  breach,  and (iii)  Parent and Sub have  failed to cure such
breach  within 10 days after  receiving  such  notice (or if such  breach is not
capable of being cured within such 10 day period,  but is capable of being cured
within 30 days,  the breaching  party shall have  commenced  good faith steps to
promptly cure such breach);

                  (d) at the  option of  Parent,  by Parent if the  Stockholders
fail to approve any matter required to be approved by such Stockholders in order
to consummate the transactions contemplated by this Agreement by April 30, 1997;

                  (e) by either  Parent or the  Company if a court of  competent
jurisdiction or  governmental,  regulatory or  administrative  agency shall have
issued a non-appealable final order, decree or ruling or taken any other action,
in each  case  having  the  effect  of  permanently  restraining,  enjoining  or
otherwise prohibiting the Merger;

                  (f) at the  option of  Parent,  by Parent if there  shall have
occurred a Material Adverse Change with respect to the Company;

                  (g) by the Company if the Closing has not  occurred by May 30,
1997 if the sole reason for the failure to close is due to Parent  having failed
to satisfy either condition to Closing set forth in Section 8.2(g) or (h); or

                  (h) by  Parent,  if the  results  of  Parent's  due  diligence
investigation of the Company and its business (to be completed prior to February
28, 1997) prove unsatisfactory in any material respect.

      SECTION 9.2.  CERTAIN  REMEDIES  UPON  TERMINATION.  If this  Agreement is
terminated:  (i)  pursuant to Section  9.1(a) (due to the mutual  consent of the
parties),  no special expense 







                     Agreement and Plan of Merger - Page 35


reimbursement  shall apply and all expenses  will be paid as provided in Section
11.2;  (ii)  pursuant  to Section  9.1(b),  9.1(d) or 9.1(f) [due to a breach of
representations and warranties by the Company or the Stockholders,  a failure by
the Stockholders to approve the transactions  contemplated herein, or a Material
Adverse Change in the business of the Company],  the Company shall pay to Parent
within five days of such termination,  an amount in cash sufficient to reimburse
Parent  and  Sub  for  all  reasonable  expenses  incurred  in  connection  with
attempting  to  consummate  the Merger and the other  transactions  contemplated
hereby (including without limitation reasonable legal, accounting and investment
banking  expenses)  (the  "TRANSACTION  EXPENSES")  up to a  maximum  amount  of
$50,000;   provided  that  Parent  shall  provide  reasonable  evidence  of  the
incurrence of such expenses.

              (b) If the Agreement is terminated  pursuant to Section  9.1(c) or
(g) [due to a breach of  Parent's  representations  or  warranties,  or Parent's
failure  to obtain  financing  for this  transaction],  Parent  shall pay to the
Company within five days of such termination the Company's  Transaction Expenses
up to a maximum  amount of  $50,000;  provided  that the Company  shall  provide
reasonable evidence of the incurrence of such expenses.

              (c) If the Agreement is terminated pursuant to Section 9.1(e), the
party not  principally  the cause of any  order  decree or ruling  shall pay the
Transaction Expenses of the other party;  provided that such party shall provide
reasonable evidence of the incurrence of such expenses.

         SECTION  9.3.   SURVIVAL  UPON   TERMINATION.   If  this  Agreement  is
terminated,  the agreements of the Company and Parent contained in Sections 5.3,
5.4, 9.1, 9.2, 9.3 and 11.2 shall survive such termination.

         SECTION 9.4. EFFECT OF TERMINATION.  In the event of the termination of
this Agreement,  nothing shall relieve any party from liability for any material
breach by any party hereof.


                                    ARTICLE X

                            SURVIVAL; INDEMNIFICATION

         SECTION 10.1. SURVIVAL. The covenants, agreements,  representations and
warranties  of the  Parent,  Company  and  the  Stockholders  contained  in this
Agreement  shall  survive  the  Closing  until the  earlier  to occur of (i) the
fifteenth  calendar  month  anniversary  of the  Closing or (ii) the  release by
Parent of audited financial  statements that include the combined  operations of
the Surviving  Corporation  and the Parent for the year ended December 31, 1997;
provided,  however,  that the  representations and warranties of the Company and
the  Stockholders  set forth in Sections  3.22(d) and (e) and 3.28 shall survive
until  the third  anniversary  of the  Closing.  Notwithstanding  the  preceding
sentences, any covenant, agreement, claim, representation or warranty in respect
of which a claim of indemnity may be sought under Section 10.2 shall survive the
time at which it would otherwise terminate pursuant to the preceding  sentences,
if notice of the  inaccuracy  or breach  thereof  giving rise to such right to a
claim of  indemnity  shall  have  been  given to the  party  against  whom  such
indemnity  may be sought  prior to such time,  and any  obligation  of indemnity
shall survive until such claim of indemnity is resolved.

         SECTION 10.2.  MUTUAL  INDEMNIFICATION.  (a) By their  approval of this
Agreement, the Stockholders, severally (based on their ownership interest in the
Company), agree to indemnify, defend, protect, and hold harmless each of Parent,
Sub and the Surviving Corporation (each in its capacity as an indemnified party,
and for purposes of this paragraph,  an  "INDEMNITEE"),  and shall reimburse the







                     Agreement and Plan of Merger - Page 36


Indemnitee  for, at all times from and after the date of this Agreement from and
against all claims, damages, losses,  liabilities,  actions, suits, proceedings,
demands, assessments,  adjustments,  costs and expenses (including specifically,
but   without   limitation,   reasonable   attorneys'   fees  and   expenses  of
investigation)  (collectively "DAMAGES") incurred by such Indemnitee as a result
of or  incident  to (i) any  breach of any  representation  or  warranty  of the
Company or any of the  Stockholders  set forth herein,  or in any other document
delivered  in  connection  herewith  or  with  respect  to  which  a  claim  for
indemnification  is brought by an  Indemnitee  within  the  applicable  survival
period  described in Section 10.1 (including any accounts  receivable  reflected
(net of reserves) on the balance  sheet of the Company  dated  December 31, 1996
which  are  not  collected  prior  to  April  30,  1997),  (ii)  any  breach  or
nonfulfillment by the Company or any of the  Stockholders,  or any noncompliance
by the Company or any of the  Stockholders  with,  any covenant,  agreement,  or
obligation  contained herein or other document delivered in connection herewith,
except to the extent waived by Parent, or (iii) any claim by a current or former
stockholder  of the Company or any other person,  firm,  corporation  or entity,
seeking to assert,  or based upon:  (A)  ownership or rights of ownership to any
shares of capital stock of the Company; (B) any rights of the stockholder (other
than the right to receive the Merger consideration pursuant to this Agreement or
appraisal  rights under the  applicable  provisions of Ohio Law),  including any
option,  preemptive rights, or rights to notice or to vote; (C) any rights under
the charter or bylaws of the Company;  (D) any claim that his, her or its shares
were  wrongfully  repurchased  by the Company,  regardless of whether an action,
suit or proceeding  can or has been made against the Company;  or (E) any Excess
Expenses, as defined in Section 11.2 below.

                  (b)  Parent   agrees  to   indemnify   the   Company  and  the
Stockholders  (for  purposes  of  this  paragraph,  each in its  capacity  as an
indemnified  party, an "INDEMNITEE")  and shall reimburse the Indemnitee for all
Damages incurred by such Indemnitee as a result of or incident to (i) any breach
of any  representation  or warranty of Parent set forth herein,  or in any other
document  delivered in connection  herewith or with respect to which a claim for
indemnification  is brought by the Company or the  Stockholder  as an Indemnitee
within the  applicable  survival  period  described in Section 10.1, or (ii) any
breach  or  nonfulfillment  by Parent or any  noncompliance  by Parent  with any
covenant,  agreement or obligation  contained herein required to be performed or
other document delivered in connection herewith,  except to the extent waived by
the  Company or  Stockholders  holding a majority of the  outstanding  shares of
Company Common Stock.

         SECTION 10.3.  THIRD PERSON  CLAIMS.  Promptly  after an Indemnitee has
received notice of or has knowledge of any claim by a person not a party to this
Agreement  ("THIRD PERSON") or the commencement of any action or proceeding by a
Third Person,  the Indemnitee  shall,  as a condition  precedent to a claim with
respect thereto being made under this Agreement,  give the Stockholders  written
notice of such claim or the commencement of such action or proceeding; provided,
however  that the failure to give such  notice will not affect the  Indemnitee's
right to indemnification  hereunder,  except to the extent that the Stockholders
have been actually  prejudiced as a result of such failure.  If the Stockholders
notify the  Indemnitee  within 30 days from the receipt of the foregoing  notice
that the Stockholders wish to defend against the claim by the Third Person, then
the  Stockholders  shall have the right to assume and control the defense of the
claim by  appropriate  proceedings  with counsel  reasonably  acceptable  to the
Indemnitee.  The Indemnitee may participate in the defense, at its sole expense,
of any such claim for which the  Stockholders  shall have  assumed  the  defense
pursuant to the preceding  sentence,  provided that counsel for the Stockholders
shall act as lead counsel in all matters pertaining to the defense or settlement
of such claims, suit or proceedings;  provided,  however,  that Indemnitee shall
control the defense of any claim or proceeding that in  Indemnitee's  reasonable
judgment  could  reasonably be expected to have a material and adverse effect on
Indemnitee's  business apart from the payment of money  damages.  The Indemnitee
shall be entitled to indemnification for the reasonable fees








                     Agreement and Plan of Merger - Page 37


and expenses of its counsel for any period  during which the  Stockholders  have
not assumed the defense of any claim. Whether or not the Stockholders shall have
assumed the defense of any claim,  neither the Indemnitee  nor the  Stockholders
shall make any  settlement  with respect to any such claim,  suit or  proceeding
without the prior consent of the other,  which consent shall not be unreasonably
withheld or  delayed.  It is  understood  and agreed  that in  situations  where
failure to settle a claim  expeditiously would reasonably be expected to have an
adverse effect on the party wishing to settle, the failure of the other party to
act upon a request for consent to such settlement  within ten (10) business days
of  receipt  of notice  thereof  shall be deemed to  constitute  consent to such
settlement for purposes of this Article X.

         SECTION 10.4.  LIMITATIONS ON INDEMNIFICATION.  (a) No Indemnitee shall
be entitled to  indemnification  for Damages pursuant to Sections  10.2(a)(i) or
10.2(a)(ii) until the aggregate amount of Damages incurred exceeds $100,000 (the
"THRESHOLD"), and then shall be entitled only to the amount of Damages in excess
of the  Threshold.  All claims for  Damages  shall be net of, and offset by, any
insurance  proceeds,  reduction  of tax  liabilities  or receipt of tax  benefit
actually  received by Parent or the Surviving  Corporation that are attributable
to such Damages. Any liability for indemnification under this Article X shall be
reduced to the extent any Damages are reduced by such a recovery or reduction.

                  (b) The Stockholders'  maximum aggregate  liability for claims
made pursuant to Section  10.2(a)(i) and (ii) shall not exceed $4,000,000 in the
aggregate;  provided,  however,  that such maximum aggregate  liability shall be
increased,  to not more than $6,500,000 in the aggregate,  to the extent of each
claim representing a breach or non-fulfillment pursuant to Section 10.2(a)(i) or
10.2(a)(ii)  which the  Stockholders  had  knowledge of prior to the Closing (or
after reasonable inquiry and  investigation,  should have had knowledge of prior
to the  Closing).  The  Parent's  maximum  aggregate  liability  for claims made
pursuant to Section 10.2(b) shall not exceed $4,000,000 in the aggregate.

                  (c)  The  limitations  provided  in  Section  10.4(a)  on  the
Threshold and Section 10.4(b) regarding  maximum  aggregate  liability and on an
Indemnitee's  right to  indemnification  under this Article X shall not apply to
Damages  for any  matters  set forth in  Section  10.2(a)(iii)  or any claim for
Damages under Sections 3.20, 3.22 and 3.28, or for Excess Expenses under Section
11.2.

         SECTION  10.5.  METHOD OF PAYMENT.  Subject to the  limitations  on the
amount of Damages set forth in Section  10.4,  and subject to the  provisions of
Section 10.6, any claims for indemnification pursuant to this Article X shall be
satisfied  by  withholding  the amount of the claim from any  remaining  payment
obligation  on the then  outstanding  principal  amount of the Notes in  inverse
order of maturity; provided, however, that no Stockholder shall be liable for an
amount in excess of the  value of the sum of the  Merger  Consideration  and the
additional consideration,  if any, paid pursuant to Section 2.5 received by such
Stockholder in the Merger.

         SECTION  10.6.  RESOLUTIONS  OF CONFLICTS;  ARBITRATION.  The following
provisions  shall  apply  with  respect  to the  assertion  of  claims  and  the
indemnification provisions of this Article X.

                  (a) The  Stockholders and Parent shall attempt promptly and in
good faith to agree upon the rights of the parties  with respect to any disputed
claims. If the Stockholders and the Parent should so agree, a memorandum setting
forth  such  agreement  shall be  prepared  and signed by both  parties  and the
Stockholders shall satisfy the claim in accordance with the terms thereof.

                  (b)  Any  dispute  or  controversy  concerning  the  indemnity
obligations  of this Article X not agreed to by the parties  pursuant to Section
10.6(a) shall be resolved in good faith by mediation among the  Stockholders and
the senior executive  officers of Parent. If such dispute can not be 







                     Agreement and Plan of Merger - Page 38


resolved by mediation  within 30 days, then except for the right of either party
to apply to a court of competent jurisdiction for a temporary restraining order,
preliminary injunction,  or other equitable relief to preserve the status quo or
prevent   irreparable   harm  pending  the  selection  and  confirmation  of  an
arbitrator,  any  continuing  dispute,  controversy  or claim arising out of, in
connection with, or in relation to the indemnity  obligations under this Article
X shall be settled by arbitration in accordance with Section 10.6(c) below.

                  (c) If no agreement can be reached  after good faith  attempts
pursuant to Section 10.6(a) and 10.6(b) within 90 days from the  commencement of
any  dispute  or  controversy,  either  Parent or the  Stockholders  may  demand
arbitration of the matter unless the amount of the damage or loss is at issue in
pending  litigation with a third party, in which event  arbitration shall not be
commenced until such amount is ascertained or both parties agree to arbitration;
and in any such event the matter shall be settled by arbitration  conducted by a
single arbitrator mutually agreeable to the Stockholders and the Parent, or if a
single  arbitrator  cannot be agreed to by the parties  within thirty (30) days,
then by three  arbitrators.  In the event of three  arbitrators,  Parent and the
Stockholders  shall  each  select one  arbitrator,  and the two  arbitrators  so
elected  shall select a third  arbitrator.  The decision of the  arbitrators  so
selected as to the validity and amount of any claim in dispute  shall be binding
and conclusive upon the parties to this Agreement,  and the parties shall act in
accordance  with  such  decision  and  satisfy  any  such  claim  in  accordance
therewith. Judgment upon any award rendered by the arbitrators may be entered in
any court having  jurisdiction.  Any mediation or  arbitration  shall be held in
Cincinnati,  Ohio. Any  arbitration  shall be conducted  under the rules then in
effect  of the  American  Arbitration  Association,  and  shall  be based on the
provisions  and  limitations  of this  Article  X. The  arbitrators  shall  have
relevant  experience in the industry of the Company and, to the extent possible,
familiarity with  acquisitions and business  combinations.  The parties agree to
compel the  arbitrator(s)  to  resolve  the  arbitration  within 120 days of the
commencement of arbitration.

         Notwithstanding anything contained herein to the contrary, no claim for
Damages,  nor ability of Parent to settle any claim  against  the Parent  Common
Stock or payment  obligations on the Notes under Section 10.5, may be made until
such claim is finally resolved  pursuant to the process and procedures set forth
above in this Section.

         SECTION 10.7 REMEDIES. The indemnification provisions of this Article X
are the sole and exclusive remedy of any party to this Agreement for a breach of
any representation,  warranty or covenant contained herein,  except with respect
to any claim based on intentional misrepresentation, fraud in the inducement, or
a similar theory.  Notwithstanding  the preceding  sentence,  from and after the
execution  and delivery of this  Agreement  and until the  Closing,  each of the
parties  acknowledges  and agrees that the other parties hereto would be damaged
irreparably  in the  event  any of the  provisions  of  this  Agreement  are not
performed in  accordance  with their  specific  terms or otherwise are breached.
Accordingly, each of the parties hereto agrees the other parties hereto shall be
entitled to an injunction to prevent  breaches of the provisions of this Article
X and to enforce  specifically  this  Agreement and the terms and  provisions of
Article X in any  competent  court  having  jurisdiction  over the  parties,  in
addition to any other remedy to which they may be entitled at law or in equity.

                                   ARTICLE XI

                                  MISCELLANEOUS

         SECTION  11.1.  SPECIFIC  PERFORMANCE.  Each  of the  parties  to  this
Agreement  hereby  acknowledges  that the other  parties  will have no  adequate
remedy  at  law if it  fails  to  perform  any of  its  obligations  under  this
Agreement.  In such  event,  each of the parties  agrees that the other  parties
shall have the right,  in addition to any other  rights it may have  (whether at
law or in equity),  to specific  performance  of this  Agreement,  except as set
forth to the contrary herein.

         SECTION 11.2.  EXPENSES.  Except as set forth in Section 9.2, all costs
and expenses  incurred in connection  with this  Agreement and the  transactions
contemplated hereby shall be paid by the party incurring such expense; provided,
however that if this  Agreement is not  terminated  and the Closing shall occur,
all such costs and expenses incurred directly on behalf of the Company and which
are  customarily  incurred  by and on behalf of the Company  (including  without
limitation  accounting,  legal and other professional  services of a routine and
recurring  nature (for  example,  annual  auditing  expenses))  shall be paid or
reimbursed by the Parent.  The Parent will  reimburse the Company  following the
Closing  for all  reasonable  and  itemized  fees and  expenses  incurred by the
Company to Taft, Stettinius & Hollister relating to the resolution of tax issues
of this  transaction  beneficial to the  Stockholders  (including,  for example,
subchapter S distributions, depreciation recapture, Section 338(h)(10) Election,
401-K distributions and similar tax issues) if the transactions  contemplated by
this  Agreement are  consummated.  All other costs and expenses  incurred by the
Company  for  the  benefit  of  the  Stockholders  or  the  Company,  or by  the
Stockholders  directly (including without limitation legal and professional fees
incurred by the Company or the  Stockholders  in connection with the negotiation
of the transactions contemplated by this Agreement), shall be paid or reimbursed
by the  Stockholders  from the Merger  Consideration  to be delivered at Closing
(the "EXCESS EXPENSES").

         SECTION  11.3.  FURTHER  ASSURANCES.  If at any time after the Closing,
Parent  or  Sub  shall  consider  it  advisable  that  any  further  conveyance,
agreements,  documents  or  instruments  or any other  things are  necessary  or
desirable to vest, perfect, confirm or record in the Surviving Corporation,  the
title to any property, rights, privileges, powers and franchises of the Company,
the  officers of the Company last in office and such other  Persons,  if any, as
the Board of  Directors  of the  Company  last in office  may  authorize,  shall
execute  and  deliver,  upon  Parent's  reasonable  request,  any and all proper
conveyances,  agreements, documents and instruments, and do all things necessary
or proper to vest,  perfect,  confirm or record title to such property,  rights,
privileges, powers and franchises in the Surviving Corporation, and otherwise to
carry out the provisions of this Agreement.

         SECTION 11.4. PARTIES IN INTEREST. All the terms and provisions of this
Agreement  shall be binding  upon,  shall  inure to the  benefit of and shall be
enforceable  by the respective  successors and permitted  assigns of the parties
hereto.  Except as set forth in Section 7.8(e),  nothing expressed or implied in
this  Agreement  is  intended or shall be  construed  to confer upon or give any
Person other than the parties hereto, their permitted successors or assigns, and
their respective  stockholders any rights or remedies under or by reason of this
Agreement or any transaction contemplated hereby or thereby.

         SECTION 11.5. ENTIRE AGREEMENT.  This Agreement and the other Operative
Documents,  together  with  the  Exhibits  and  Schedules  hereto  and  thereto,
supersede any other agreement,  whether written or oral, that may have been made
or entered into by Parent,  Sub and the Company (or by any officers,  directors,
stockholders  or  partners  of any of  such  parties)  relating  to the  matters
contemplated hereby. This Agreement and the other Operative Documents,  together
with the  Exhibits  and  Schedules






                     Agreement and Plan of Merger - Page 40


hereto and thereto,  constitute the entire  agreement by the parties,  and there
are no agreements or commitments except as set forth herein or therein.

         SECTION 11.6 AMENDMENT OR  MODIFICATION.  This Agreement may be amended
only with the written consent of Parent, Sub, the Stockholders and the Company.

         SECTION  11.7.  WAIVER.  Any party to this  Agreement  may,  by written
notice to the other  parties  to this  Agreement,  (a)  extend  the time for the
performance of any of the  obligations or other actions of the other parties for
its  benefit  under  this   Agreement;   (b)  waive  any   inaccuracies  in  the
representations  or warranties of the other parties made to it contained in this
Agreement;  (c) waive  compliance with any of the conditions or covenants of the
other  parties  for its benefit  contained  in this  Agreement;  or (d) waive or
modify  performance  of any of the  obligations  of the  other  parties  for its
benefit under this Agreement.  Except as provided in the preceding sentence,  no
action taken pursuant to this  Agreement  including any  investigation  by or on
behalf of any party,  shall be deemed to constitute a waiver by the party taking
such  action of  compliance  with any  representations,  warranties,  covenants,
conditions or agreements  contained in this Agreement.  The failure of any party
hereto to enforce at any time any of the provisions of this  Agreement  shall in
no way be  construed  to be a waiver  of any such  provision,  nor in any way to
affect the validity of this Agreement or any part hereof or thereof or the right
of such party thereafter to enforce each and every such provision.  No waiver of
any breach of or non-compliance with this Agreement shall be held to be a waiver
of any other or subsequent breach or non-compliance.

         SECTION  11.8.  ASSIGNABILITY.  Neither this  Agreement  nor any rights
hereunder shall be assignable,  except (i) by the Company with the prior written
consent of Parent, or (ii) by Parent or by Sub with the prior written consent of
the Company.

and exercisable upon delivery of the Warrant,  40% will become  exercisable upon
filing a 510(k)  or other  application  for the  BioLoc  Technology  or  DynaGen
Technology  with the FDA, and the  remaining  40% will become  exercisable  upon
approval of such  application  by the FDA;  provided,  however,  that the holder
continues to work on the BioLoc Technology or DynaGen  Technology and is engaged
by the Company as a consultant at the times of each of the foregoing milestones.
If the






                                      -3-

services  of the  holder of the  warrant  as a  consultant  to the  Company  are
terminated  without  cause,  then this  Warrant  shall  become  fully vested and
immediately  exercisable  at  the  time  of  any  FDA  application.  The  BioLoc
Technology  and DynaGen  Technology  is defined in a certain  Exclusive  License
Agreement  between the Company  and BioLoc,  Inc.  dated as of December 6, 1996.
DynaGen shall use  commercially  reasonable  efforts to file and prosecute  such
application with the FDA.

                  1.4 CASHLESS EXERCISE FEATURE -- RIGHT TO CONVERT WARRANT INTO
COMMON  STOCK.  (a) In  addition  to and  without  limiting  the  rights  of the
Warrantholder under the terms of this Warrant,  the Warrantholder shall have the
right (the  "CONVERSION  RIGHT") to convert this Warrant or any portion  thereof
into shares of Common Stock as provided in this Section at any time or from time
to time  prior to its  expiration,  subject  to the  restrictions  set  forth in
paragraph (c) hereof.  In lieu of exercising  this warrant for cash,  the holder
may elect to surrender  this  warrant for  conversion  and to receive  shares of
Common Stock equal to the value of this Warrant (or the portion being cancelled,
surrendered and converted) by surrender of this Warrant to the Company  together
with notice of such  election.  Upon such event,  the Company shall issue to the
holder a number of shares of the  Company's  Common Stock  computed by using the
following formula:
                         X  MINUS Y (A MINUS B)
                                        A
Where:            X = The  number of shares of Common  Stock to be issued to the
                  holder;  
                  Y = The number of shares of Common Stock  purchasable
                      under this  Warrant;  
                  A = The "Fair Market Value" of one share of the Common Stock;
                      and 
                  B = The Exercise Price of the Warrant (as adjusted to the date
                      of the calculation).

         Upon  exercise of the  Conversion  Right with  respect to a  particular
number of shares  subject to this  Warrant,  the  Company  shall  deliver to the
Warrantholder, without payment by the Warrantholder of any exercise price or any
cash or other consideration,  that number of shares of Common Stock equal to the
number  computed  using  the above  formula.  Notwithstanding  anything  in this
Section to the contrary,  the Conversion  Right cannot be exercised with respect
to a number  of  Converted  Warrant  Shares  having  a value  below  $1,000.  No
fractional  shares shall be issuable upon exercised of the Conversion Right, and
if the number of shares to be issued in accordance with the foregoing formula is
other than a whole number,  the Company shall pay to the Warrantholder an amount
in cash equal to the Fair Market Value of the resulting fractional share.

         (b) The Conversion  Right may be exercised by the  Warrantholder by the
surrender of this Warrant at the principal office of the Company together with a
written statement specifying that the Warrantholder  thereby intends to exercise
the  Conversion  Right and  indicating  the number of shares of Common  Stock or
authorized  Common Stock subject to this Warrant which are being  surrendered in
exercise of the  Conversion  Right.  Such  conversion  shall be  effective  upon
receipt by the  Company of this  Warrant  together  with the  aforesaid  written
statement,  or on such  later  date as is  specified  therein  (the  "CONVERSION
DATE"), but not later than the expiration date of this Warrant.





                                      -4-

         (c) In the event the Conversion  Right would,  at any time this Warrant
remains  outstanding,  be deemed by the Company's  independent  certified public
accountants  to give rise to a charge to the  Company's  earnings for  financial
reporting purposes, then the Conversion Right shall automatically terminate upon
the Company's  written notice to the  Warrantholder  of such adverse  accounting
treatment.

         (d) For purposes of this Section, the "FAIR MARKET VALUE" of a share of
Common  Stock  or  authorized   Common  Stock  as  of  a  particular  date  (the
"DETERMINATION DATE") shall mean:

                  (i) if the  Company's  Common  Stock  is  then  traded  on any
nationally-recognized  stock  exchange or quoted on the NASDAQ  National  Market
System or  Small-Cap  Market,  the average of the closing sale prices for the 20
trading days preceding the  Determination  Date, as reported by such exchange or
system,  as  reported  in The Wall  Street  Journal  or any  other  publication,
including the NASD;

                  (ii) if the  Company's  Common  Stock  is then  traded  on the
over-the-counter market, the average of the closing bid and closing asked prices
for the 30 trading days  preceding  the  Determination  Date, as reported in The
Wall Street Journal or by any market maker; or

                  (iii)  if  quotations  for  the  Company's   Common  Stock  or
authorized  Common  Stock is not readily  available  as set forth in (i) or (ii)
above, then as determined in good faith by the Company's Board of Directors upon
a review of all relevant factors,  including,  without limitation,  the price at
which  shares of the  Company's  Common Stock or  authorized  Common Stock could
reasonably be expected to be sold in an arms-length transaction, for cash, other
than on an  installment  basis,  to a person not employed by,  controlled by, in
control of or under common control with the Company,  which determination by the
Board of Directors shall give due consideration to recent transactions involving
shares of the Common Stock or  authorized  Common  Stock,  if any,  revenues and
earnings of the Company to the date of such  determination  (if any),  projected
revenues and earnings of the Company, the effect of the transfer restrictions to
which the shares are subject  under law, the absence of a public  market for the
Common Stock or authorized  Common Stock, and such other matters as the Board of
Directors deems pertinent. Such determination by the Board of Directors shall be
conclusive and binding.

         2. DELIVERY OF STOCK  CERTIFICATES ON EXERCISE.  As soon as practicable
after the exercise of this  Warrant in full or in part,  and in any event within
thirty (30) days thereafter,  the Company at its expense  (including the payment
by it of any applicable  issue taxes) will cause to be issued in the name of and
delivered to the holder  hereof,  or as such holder (upon payment by such holder
of any applicable  transfer taxes) may direct, a certificate or certificates for
the number of fully  paid and  non-assessable  shares of Common  Stock (or Other
Securities)  to which such holder shall be entitled on such  exercise,  plus, in
lieu of any fractional  share to which such holder would  otherwise be entitled,
cash equal to such fraction  multiplied by the then current  market value of one
full share.





                                      -5-

         3.       ADJUSTMENT FOR REORGANIZATION, CONSOLIDATION OR MERGER.

                  3.1.  REORGANIZATION,  CONSOLIDATION OR MERGER. In case at any
time or from time to time,  the Company shall (a) effect a  reorganization,  (b)
consolidate  with or merge into any other person or entity,  or (c) transfer all
or  substantially  all of its capital  stock,  properties or assets to any other
person  under  any plan or  arrangement  contemplating  the  dissolution  of the
Company,  then, in each such case,  the holder of this Warrant,  on the exercise
hereof as  provided  in  Section 1 at any time  after the  consummation  of such
reorganization,   consolidation   or  merger  or  the  effective  date  of  such
dissolution,  as the case may be,  shall  receive,  upon the proper and rightful
exercise  of this  Warrant,  in lieu of the Common  Stock (or Other  Securities)
issuable on such exercise prior to such consummation or such effective date, the
stock and other  securities and property  (including  cash) to which such holder
would have been  entitled  upon such  consummation  or in  connection  with such
dissolution,  as the case may be, if such holder had so exercised  this Warrant,
immediately  prior  thereto,  all subject to further  adjustment  thereafter  as
provided in Sections 4 and 5.

                  3.2.  CONTINUATION OF TERMS. Upon any corporate event referred
to in this Section 3, this Warrant  shall  continue in full force and effect and
the terms hereof shall be applicable to the shares of stock and Other Securities
and property  receivable on the exercise of this Warrant after the  consummation
of such  reorganization,  consolidation or merger, as the case may be, and shall
be binding upon the issuer of any such stock or other securities.

         4. ADJUSTMENTS FOR STOCK DIVIDENDS AND STOCK SPLITS.  In the event that
the Company shall (i) issue additional  shares of the Common Stock as a dividend
or  other   distribution  on  outstanding   Common  Stock,  (ii)  subdivide  its
outstanding  shares of Common Stock, or (iii) combine its outstanding  shares of
the Common Stock into a smaller  number of shares of the Common Stock,  then, in
each such event, the Exercise Price shall,  simultaneously with the happening of
such event, be adjusted by multiplying  the then prevailing  Exercise Price by a
fraction,  the  numerator of which shall be the number of shares of Common Stock
outstanding  immediately prior to such event (calculated assuming the conversion
or exchange of all outstanding shares of convertible or exchangeable  securities
of the Company which are convertible or exchangeable  into, or exercisable  for,
shares of Common  Stock)  and the  denominator  of which  shall be the number of
shares of Common  Stock  outstanding  immediately  after such event  (calculated
assuming the conversion or exchange of all outstanding  shares of convertible or
exchangeable  securities of the Company which are  convertible  or  exchangeable
into, or exercisable  for, shares of Common Stock),  and the product so obtained
shall thereafter be the Exercise Price then in effect. The Exercise Price, as so
adjusted,  shall be  readjusted  in the same  manner upon the  happening  of any
successive  event or events  described  herein in this  Section 4. The holder of
this Warrant shall thereafter,  on the exercise hereof as provided in Section 1,
be  entitled  to receive  that number of shares of Common  Stock  determined  by
multiplying  the number of shares of Common Stock which would otherwise (but for
the provisions of this Section 4) be issuable on such exercise, by a fraction of
which (i) the numerator is the Exercise Price which would otherwise (but for the
provisions  of this  Section 4) be in effect,  and (ii) the  denominator  is the
Exercise Price in effect on the date of such exercise.





                                      -6-

         5.   ADJUSTMENT   FOR   DIVIDENDS   IN  OTHER   STOCK,   PROPERTY   AND
RECLASSIFICATIONS.  In case at any time or from  time to time,  the  holders  of
Common  Stock (or Other  Securities)  shall have  received,  or (on or after the
record date fixed for the  determination  of  stockholders  eligible to receive)
shall have become entitled to receive, without payment therefor,

         (a) other or additional  stock or other  securities or property  (other
than cash) by way of dividend, or

         (b)  other  or  additional   stock  or  other  securities  or  property
(including   cash)   by   way   of   spin-off,    split-up,    reclassification,
recapitalization, combination of shares or similar corporate rearrangement,

other than additional shares of Common Stock (or Other  Securities)  issued as a
stock dividend or in a stock-split (adjustments in respect of which, in the case
of Common Stock,  are provided for in Section 4), then and in each such case the
holder of this Warrant,  on the exercise  hereof as provided in Section 1, shall
be  entitled  to  receive  the  amount  of other or  additional  stock and other
securities and property  (including cash in the cases referred to in subdivision
(b) of this Section 5) which such holder would hold on the date of such exercise
if on the  date of  distribution  of such  other  or  additional  stock or other
securities  and  property,  or on the  record  date  fixed for  determining  the
shareholders  entitled  to  receive  such  other  or  additional  stock or other
securities and property, such holder had been the holder of record of the number
of  shares  of  Common  Stock  called  for on the face of this  Warrant  and had
thereafter, during the period from the date thereof to and including the date of
such exercise,  retained such shares and all such other or additional  stock and
other  securities  and  property  (including  cash in the cases  referred  to in
subdivision (b) of this Section 5) receivable by such holder as aforesaid during
such period,  giving effect to all adjustments  called for during such period by
Sections 3 and 4.

         6.       NOTICES OF RECORD DATE.  In the event of

         (a) any taking by the  Company of a record of the  holders of any class
or  securities  for the  purpose of  determining  the  holders  thereof  who are
entitled  to  receive  any  dividend  or  other  distribution,  or any  right to
subscribe for, purchase or otherwise acquire any shares of stock of any class or
any other securities or property, or to receive any other right, or

         (b) any capital  reorganization of the Company, any reclassification or
recapitalization  of the capital  stock of the Company or any transfer of all or
substantially all the assets of the Company to or consolidation or merger of the
Company with or into any other person, or

         (c) any voluntary or involuntary dissolution, liquidation or winding-up
of the Company,

then and in each such event the  Company  will mail or cause to be mailed to the
holder of this Warrant a notice specifying (i) the date on which any such record
is to be taken for the  purpose of such  dividend,  distribution  or right,  and
stating the amount and character of such dividend,  distribution  or right,  and
(ii)   the   date  on   which   any   such   reorganization,   reclassification,





                                      -7-

recapitalization,  transfer, consolidation,  merger, dissolution, liquidation or
winding-up is to take place,  and the time,  if any is to be fixed,  as of which
the holders of record of Common Stock (or Other Securities) shall be entitled to
exchange  their shares of Common Stock (or Other  Securities)  for securities or
other   property   deliverable   on   such   reorganization,   reclassification,
recapitalization,  transfer, consolidation,  merger, dissolution, liquidation or
winding-up.  Such notice  shall be mailed at least twenty (20) days prior to the
date specified in such notice on which any such action is to be taken.

         7.  RESERVATION OF STOCK  ISSUABLE ON EXERCISE OF WARRANT.  The Company
will at all times reserve and keep  available,  solely for issuance and delivery
on the  exercise of the  Warrant,  all shares of Common  Stock from time to time
issuable on the  exercise of the  Warrant;  the shares of Common Stock which the
holder of this Warrant  shall  receive upon exercise of the Warrant will be duly
authorized, validly issued, fully paid and non-assessable.

         8.  EXCHANGE OF WARRANT.  On surrender  for  exchange of this  Warrant,
properly  endorsed,  to the  Company,  the Company at its expense will issue and
deliver to or on the order of the holder  thereof a new  Warrant or  Warrants of
like  tenor,  in the name of such  holder or as such  holder (on payment by such
holder of any applicable transfer taxes) may direct, calling in the aggregate on
the face or faces thereof for the number of shares of Common Stock called for on
the face or faces of the Warrant or Warrants so surrendered.

         9.   REPLACEMENT  OF  WARRANT.   On  receipt  of  evidence   reasonably
satisfactory  to the Company of the loss,  theft,  destruction  or mutilation of
this Warrant  and, in the case of any such loss,  theft or  destruction  of this
Warrant,   on  delivery  of  an  indemnity   agreement  or  security  reasonably
satisfactory  in form and  amount  to the  Company  or,  in the case of any such
mutilation,  on surrender and  cancellation of such Warrant,  the Company at its
expense will execute and deliver, in lieu thereof, a new Warrant of like tenor.

         10.  WARRANTHOLDER  NOT DEEMED  STOCKHOLDER;  RESTRICTIONS ON TRANSFER.
This Warrant is issued upon the following  terms, to all of which each holder or
owner hereof by the taking hereof consents and agrees:

         (a) No holder of this Warrant  shall,  as such, be deemed the holder of
      Common  Stock  that  may at any time be  issuable  upon  exercise  of this
      Warrant for any purpose whatsoever, nor shall anything contained herein be
      construed  to confer  upon such  holder,  as such,  any of the rights of a
      stockholder of the Company until such holder shall have  delivered  formal
      notice to the Company of an intention to exercise this  Warrant,  tendered
      promptly  the  consideration   required  for  exercise  (whether  cash  or
      securities), exercised the Warrant, and been issued shares of Common Stock
      in accordance with the provisions hereof.

         (b)  Neither  this  Warrant  nor any shares of Common  Stock  purchased
      pursuant to this Warrant shall be registered  under the  Securities Act of
      1933  (the  "SECURITIES   ACT")  and  applicable  state  securities  laws.
      Therefore,  the  Company may  require,  as a  condition  of  allowing  the
      transfer or exchange of this  Warrant or such  shares,  that the holder or
      transferee of this Warrant or such shares,  as the case may be, furnish to
      the Company an opinion of





                                      -8-

      counsel  acceptable  to the  Company to the effect  that such  transfer or
      exchange may be made without  registration  under the  Securities  Act and
      applicable state  securities laws. The certificates  evidencing the shares
      of Common Stock issued on the exercise of the Warrant  shall bear a legend
      to the effect that the shares evidenced by such certificates have not been
      registered under the Securities Act and applicable state securities laws.

         (c) This Warrant is not transferable or assignable to any party without
      the prior written consent of the Company, and accompanied by an opinion of
      counsel  satisfactory  to the Company  that such  transfer is  permissible
      under applicable law.

         11. NOTICES.  All notices and other  communications from the Company to
the holder of this  Warrant  shall be mailed by (i) first  class  mail,  postage
prepaid,  (ii) electronic  facsimile  transmission,  or (iii) express  overnight
courier  service,  at such address as may have been  furnished to the Company in
writing by such  holder or,  until any such holder  furnishes  to the Company an
address, then to, and at the address of, the last holder of this Warrant who has
so furnished an address to the Company.

         12.  MISCELLANEOUS.  This  Warrant  and any term hereof may be changed,
waived,  discharged or terminated only by an instrument in writing signed by the
party against which enforcement of such change, waiver, discharge or termination
is sought.  This Warrant and the shares of Common Stock  underlying this Warrant
shall be construed and enforced in  accordance  with and governed by the laws of
the State of Delaware.  The  invalidity  or  unenforceability  of any  provision
hereof  shall in no way  affect  the  validity  or  enforceability  of any other
provision.

         13.      REGISTRATION RIGHTS.

                  13.1 SHORT-FORM REGISTRATIONS ON FORM S-3. At such time when a
510(k) or other  application has been filed for the BioLoc Technology or DynaGen
Technology and this Warrant is at least sixty percent (60%) vested in accordance
with  Section  1.3, at the request of the  holders of at least  seventy  percent
(70%) of the shares of Common Stock  underlying  this Warrant (the  "REGISTRABLE
SHARES"),  the  Company  shall  use its  best  efforts  to  file a  registration
statement  on Form S-3 (to the extent  such form is  available  to the  Company)
covering the resale of the Shares  underlying  this  Warrant  (the  "REGISTRABLE
SHARES").  The  Company  will so  notify  each  holder  of  Registrable  Shares,
including each holder who has a right to acquire  Registrable  Shares,  and then
shall, as expeditiously  as possible (using  commercially  reasonable  efforts),
effect  qualification  and registration  under the Securities Act on Form S-3 of
all or such  portion of the  Registrable  Shares as the holder or holders  shall
specify,  and shall thereafter  maintain the  effectiveness of such Registration
Statement until such shares have been sold or until the registration  obligation
terminates under Section 13.3.

         The  Company  shall  not be  required  to  effect  more  than  one  (1)
registration  on Form S-3. The  Company's  obligations  under this Section shall
expire  three (3) years after the  issuance  date of this  Warrant.  The Company
agrees to qualify or register the Shares under  applicable  state law,  list the
shares wherever the Common Stock is then listed and supplement the prospectus as
necessary from time to time to keep it current.





                                      -9-


                  13.2  EXPENSES.  In the case of a  registration  under Section
13.1,  the Company  shall bear the  expenses of any filing of any  registration,
including but not limited to printing legal and accounting expenses,  Securities
and Exchange Commission and NASD filing fees and all related "Blue Sky" fees and
expenses; provided, however, that the Company shall have no obligation to pay or
otherwise  bear  any  portion  of the  underwriters'  commissions  or  discounts
attributable  to the  securities  being  offered  and sold by the holder of this
Warrant,  or the fees and  expenses of any  counsel,  tax advisor or  accountant
selected by such holder in connection with the registration of the securities.

                  13.3 EXPIRATION OF REGISTRATION RIGHTS. The obligations of the
Company  under this  Section 13 to  register  the  securities  shall  expire and
terminate  at such  time as the  holder of this  Warrant  shall be  entitled  or
eligible to sell the shares of Common  Stock  underlying  this  Warrant  without
restriction and without a need for the filing of a registration  statement under
the Securities Act of 1933,  including  without  limitation,  for any resales of
restricted securities made pursuant to Rule 144 as promulgated by the Securities
and Exchange Commission.

                  13.4  DELAY OF  REGISTRATION.  For a period  not to exceed 120
days,  the Company  shall not be obligated to prepare and file,  or be prevented
from delaying or abandoning,  a registration  statement pursuant to this Section
13 at any time when the Company, in its good faith judgment by the management of
the Company, with the advice of counsel, reasonably believes:

                           (I) that the filing thereof at the time requested, or
the offering of  Registrable  Shares  pursuant  thereto,  would  materially  and
adversely affect (a) a pending or scheduled public offering or private placement
of the  Company's  securities,  (b) an  acquisition,  merger,  consolidation  or
similar  transaction  by or of the  Company,  (c)  pre-existing  and  continuing
negotiations,  discussions  or  pending  proposals  with  respect  to any of the
foregoing transactions, or (d) the financial condition of the Company in view of
the  disclosure of any pending or threatened  litigation,  claim,  assessment or
governmental investigation which may be required thereby; and

                           (II)  that  the  failure  to  disclose  any  material
information  with  respect  to the  foregoing  would  cause a  violation  of the
Securities Act or the Securities Exchange Act of 1934.

                  13.5  INDEMNIFICATION OF HOLDERS OF REGISTRABLE SHARES. In the
event  that the  Company  registers  any of the  Registrable  Shares  under  the
Securities  Act, the Company will  indemnify  and hold  harmless each holder and
each underwriter of the Registrable Shares (including their officers, directors,
affiliates  and partners) so registered  (including any broker or dealer through
whom such shares may be sold) and each person,  if any, who controls such holder
or any such  underwriter  within the meaning of Section 15 of the Securities Act
from and against any and all losses, claims,  damages,  expenses or liabilities,
joint  or  several,  to  which  they or any of them  become  subject  under  the
Securities Act,  applicable  state securities laws or under any other statute or
at common law or otherwise,  as incurred,  and, except as hereinafter  provided,
will reimburse each such holder, each such underwriter and each such controlling
person, if any, 







                                      -10-


for any legal or other  expenses  reasonably  incurred by them or any of them in
connection with  investigating or defending any actions whether or not resulting
in any liability, insofar as such losses, claims, damages, expenses, liabilities
or actions arise out of or are based upon any untrue statement or alleged untrue
statement of a material fact contained in the registration statement under which
such Securities were registered under the Securities Act, in any filing with any
state securities commission in any preliminary or amended preliminary prospectus
or in the final prospectus (or the registration  statement or prospectus as from
time to time amended or  supplemented  by the  Company),  or arise out of or are
based upon the  omission or alleged  omission to state  therein a material  fact
required  to be stated  therein  or  necessary  in order to make the  statements
therein,  in the  light  of the  circumstances  in which  they  were  made,  not
misleading,  or  any  violation  by  the  Company  of  any  rule  or  regulation
promulgated  under the Securities Act or any state securities laws applicable to
the  Company  and  relating  to action or  inaction  required  of the Company in
connection with such registration.

         Notwithstanding the foregoing,  the Company shall have no obligation to
indemnify  any holder,  underwriter  or  controlling  person if: (i) such untrue
statement or omission was made in such  registration  statement,  preliminary or
amended  preliminary  prospectus  or final  prospectus  in reliance  upon and in
conformity  with  information  furnished in writing to the Company in connection
therewith by such holder of Registrable  Shares (in the case of  indemnification
of such  holder),  such  underwriter  (in the  case of  indemnification  of such
underwriter) or such controlling  person (in the case of indemnification of such
controlling  person)  expressly  for use therein,  or (ii) in the case of a sale
directly  by  such  holder  of  Registrable  Shares  (including  a sale  of such
Registrable   Shares  through  any  underwriter   retained  by  such  holder  of

                          COMMON STOCK PURCHASE WARRANT


         DYNAGEN, INC., a Delaware corporation (the "COMPANY"), hereby certifies
that,  in  consideration  of the  payment  of $100  (receipt  of which is hereby
acknowledged), RICH THERIAULT is entitled, subject to the terms set forth below,
to purchase from the Company,  commencing December 10, 1996, at any time or from

December 31, 2003, 41,000 fully paid and non-assessable  shares of Common Stock,
$.01 par value,  of the Company,  at an exercise price per share equal to $1.44.
Such exercise  price per share as adjusted from time to time as herein  provided
is referred to herein as the "EXERCISE PRICE".  The number and character of such
shares of Common  Stock and the  Exercise  Price are  subject to  adjustment  as
provided  herein.  THIS WARRANT IS EXERCISABLE IN  INSTALLMENTS,  SUBJECT TO THE
SATISFACTION OF CERTAIN CONDITIONS AS SET FORTH IN SECTION 1.3 BELOW. NO PORTION
OF THIS WARRANT MAY BE EXERCISED UNLESS SUCH CONDITIONS HAVE BEEN SATISFIED WITH
RESPECT TO THE CONDITIONS REGARDING EXERCISABILITY.

         As used  herein  the  following  terms,  unless the  context  otherwise
requires, have the following respective meanings:

         (a)  The  term  "COMPANY"  shall  include  DynaGen,  Inc.,  a  Delaware
corporation,  and any corporation  which shall succeed or assume the obligations
of the Company hereunder.

         (b) The term "COMMON  STOCK"  includes (a) the Company's  Common Stock,
$.01 par value per share,  as  authorized,  (b) any other  capital  stock of any
class or classes  (however  designated)  of the Company,  authorized on or after
such date, the holders of which shall have the





                                      -2-

right,  without  limitation  as to  amount,  either  to all or to a share of the
balance of current  dividends  and  liquidating  dividends  after the payment of
dividends  and  distributions  on any shares  entitled  to  preference,  and the
holders of which shall ordinarily, in the absence of contingencies,  be entitled
to vote for the election of a majority of directors of the Company  (even though
the right so to vote has been suspended by the happening of such a contingency),
(c) any other securities into which or for which any of the securities described
in  (a)  or  (b)  may  be  converted   or  exchanged   pursuant  to  a  plan  of
recapitalization,  reorganization,  merger, sale of assets or otherwise,  or the
conversion of promissory notes or other obligations of the Company.

         (c) The term "OTHER  SECURITIES" refers to any stock (other than Common
Stock) and other  securities  of the Company or any other person  (corporate  or
otherwise)  which the holder of this  Warrant at any time shall be  entitled  to
receive,  or shall have received,  on the exercise of the Warrant, in lieu of or
in  addition  to Common  Stock,  or which at any time shall be issuable or shall
have been  issued in exchange  for or in  replacement  of Common  Stock or Other
Securities pursuant to Sections 3 or 4 or otherwise.

         1.       EXERCISE OF WARRANT.

                  1.1. FULL  EXERCISE.  This Warrant may be exercised in full by
the holder hereof by surrender of this Warrant, with the form of subscription at
the end hereof duly  executed by such  holder,  to the Company at its  principal
office,  accompanied by payment,  in cash or by certified or official bank check
payable to the order of the Company,  in the amount  obtained by multiplying the
number of shares of Common Stock for which this Warrant is then  exercisable  by
the Exercise Price then in effect.

                  1.2. PARTIAL  EXERCISE.  This Warrant may be exercised in part
by surrender of this Warrant in the manner and at the place  provided in Section
1.1 except that the amount payable by the holder on such partial  exercise shall
be the amount  obtained by multiplying  (a) the number of shares of Common Stock
designated  by the  holder  in the  subscription  at the end  hereof  by (b) the
Exercise Price then in effect.  On any such partial  exercise the Company at its
expense  will  forthwith  issue and  deliver  to or upon the order of the holder
hereof a new Warrant or Warrants of like tenor, in the name of the holder hereof
or as such holder (upon payment by such holder of any applicable transfer taxes)
may  request,  calling in the  aggregate  on the face or faces  thereof  for the
number of shares of Common Stock for which such Warrant or Warrants may still be
exercised.

                  1.3  CONDITIONS  REGARDING  EXERCISABILITY.  Portions  of this
Warrant are exercisable  only upon the satisfaction of certain  conditions,  and
unlesss such  conditions  are  satisfied,  only that portion of this Warrant for
which the  conditions  have been  previously  satisfied  may be exercised at any
time.   The  Warrant  will  vest  and  become   exercisable   in  the  following
installments:  20% of the shares of Common  Stock under this  Warrant are vested
and exercisable upon delivery of the Warrant,  40% will become  exercisable upon
filing a 510(k)  or other  application  for the  BioLoc  Technology  or  DynaGen
Technology  with the FDA, and the  remaining  40% will become  exercisable  upon
approval of such  application  by the FDA;  provided,  however,  that the holder
continues to work on the BioLoc Technology or DynaGen  Technology and is engaged
by the Company as a consultant at the times of each of the foregoing milestones.
If the






                                      -3-

services  of the  holder of the  warrant  as a  consultant  to the  Company  are
terminated  without  cause,  then this  Warrant  shall  become  fully vested and
immediately  exercisable  at  the  time  of  any  FDA  application.  The  BioLoc
Technology  and DynaGen  Technology  is defined in a certain  Exclusive  License
Agreement  between the Company  and BioLoc,  Inc.  dated as of December 6, 1996.
DynaGen shall use  commercially  reasonable  efforts to file and prosecute  such
application with the FDA.

                  1.4 CASHLESS EXERCISE FEATURE -- RIGHT TO CONVERT WARRANT INTO
COMMON  STOCK.  (a) In  addition  to and  without  limiting  the  rights  of the
Warrantholder under the terms of this Warrant,  the Warrantholder shall have the
right (the  "CONVERSION  RIGHT") to convert this Warrant or any portion  thereof
into shares of Common Stock as provided in this Section at any time or from time
to time  prior to its  expiration,  subject  to the  restrictions  set  forth in
paragraph (c) hereof.  In lieu of exercising  this warrant for cash,  the holder
may elect to surrender  this  warrant for  conversion  and to receive  shares of
Common Stock equal to the value of this Warrant (or the portion being cancelled,
surrendered and converted) by surrender of this Warrant to the Company  together
with notice of such  election.  Upon such event,  the Company shall issue to the
holder a number of shares of the  Company's  Common Stock  computed by using the
following formula:
                         X  MINUS Y (A MINUS B)
                                        A
Where:            X = The  number of shares of Common  Stock to be issued to the
                      holder; 
                  Y = The number of shares of Common Stock  purchasable  under 
                      this  Warrant;  
                  A = The "Fair Market Value" of one share of the Common Stock;
                      and 
                  B = The Exercise Price of the Warrant (as adjusted to the date
                      of the calculation).

         Upon  exercise of the  Conversion  Right with  respect to a  particular
number of shares  subject to this  Warrant,  the  Company  shall  deliver to the
Warrantholder, without payment by the Warrantholder of any exercise price or any
cash or other consideration,  that number of shares of Common Stock equal to the
number  computed  using  the above  formula.  Notwithstanding  anything  in this
Section to the contrary,  the Conversion  Right cannot be exercised with respect
to a number  of  Converted  Warrant  Shares  having  a value  below  $1,000.  No
fractional  shares shall be issuable upon exercised of the Conversion Right, and
if the number of shares to be issued in accordance with the foregoing formula is
other than a whole number,  the Company shall pay to the Warrantholder an amount
in cash equal to the Fair Market Value of the resulting fractional share.

         (b) The Conversion  Right may be exercised by the  Warrantholder by the
surrender of this Warrant at the principal office of the Company together with a
written statement specifying that the Warrantholder  thereby intends to exercise
the  Conversion  Right and  indicating  the number of shares of Common  Stock or
authorized  Common Stock subject to this Warrant which are being  surrendered in
exercise of the  Conversion  Right.  Such  conversion  shall be  effective  upon
receipt by the  Company of this  Warrant  together  with the  aforesaid  written
statement,  or on such  later  date as is  specified  therein  (the  "CONVERSION
DATE"), but not later than the expiration date of this Warrant.





                                      -4-

         (c) In the event the Conversion  Right would,  at any time this Warrant
remains  outstanding,  be deemed by the Company's  independent  certified public
accountants  to give rise to a charge to the  Company's  earnings for  financial
reporting purposes, then the Conversion Right shall automatically terminate upon
the Company's  written notice to the  Warrantholder  of such adverse  accounting
treatment.

         (d) For purposes of this Section, the "FAIR MARKET VALUE" of a share of
Common  Stock  or  authorized   Common  Stock  as  of  a  particular  date  (the
"DETERMINATION DATE") shall mean:

                  (i) if the  Company's  Common  Stock  is  then  traded  on any
nationally-recognized  stock  exchange or quoted on the NASDAQ  National  Market
System or  Small-Cap  Market,  the average of the closing sale prices for the 20
trading days preceding the  Determination  Date, as reported by such exchange or
system,  as  reported  in The Wall  Street  Journal  or any  other  publication,
including the NASD;

                  (ii) if the  Company's  Common  Stock  is then  traded  on the
over-the-counter market, the average of the closing bid and closing asked prices
for the 30 trading days  preceding  the  Determination  Date, as reported in The
Wall Street Journal or by any market maker; or

                  (iii)  if  quotations  for  the  Company's   Common  Stock  or
authorized  Common  Stock is not readily  available  as set forth in (i) or (ii)
above, then as determined in good faith by the Company's Board of Directors upon
a review of all relevant factors,  including,  without limitation,  the price at
which  shares of the  Company's  Common Stock or  authorized  Common Stock could
reasonably be expected to be sold in an arms-length transaction, for cash, other
than on an  installment  basis,  to a person not employed by,  controlled by, in
control of or under common control with the Company,  which determination by the
Board of Directors shall give due consideration to recent transactions involving
shares of the Common Stock or  authorized  Common  Stock,  if any,  revenues and
earnings of the Company to the date of such  determination  (if any),  projected
revenues and earnings of the Company, the effect of the transfer restrictions to
which the shares are subject  under law, the absence of a public  market for the
Common Stock or authorized  Common Stock, and such other matters as the Board of
Directors deems pertinent. Such determination by the Board of Directors shall be
conclusive and binding.

         2. DELIVERY OF STOCK  CERTIFICATES ON EXERCISE.  As soon as practicable
after the exercise of this  Warrant in full or in part,  and in any event within
thirty (30) days thereafter,  the Company at its expense  (including the payment
by it of any applicable  issue taxes) will cause to be issued in the name of and
delivered to the holder  hereof,  or as such holder (upon payment by such holder
of any applicable  transfer taxes) may direct, a certificate or certificates for
the number of fully  paid and  non-assessable  shares of Common  Stock (or Other
Securities)  to which such holder shall be entitled on such  exercise,  plus, in
lieu of any fractional  share to which such holder would  otherwise be entitled,
cash equal to such fraction  multiplied by the then current  market value of one
full share.






                                      -5-

         3.       ADJUSTMENT FOR REORGANIZATION, CONSOLIDATION OR MERGER.

                  3.1.  REORGANIZATION,  CONSOLIDATION OR MERGER. In case at any
time or from time to time,  the Company shall (a) effect a  reorganization,  (b)
consolidate  with or merge into any other person or entity,  or (c) transfer all
or  substantially  all of its capital  stock,  properties or assets to any other
person  under  any plan or  arrangement  contemplating  the  dissolution  of the
Company,  then, in each such case,  the holder of this Warrant,  on the exercise
hereof as  provided  in  Section 1 at any time  after the  consummation  of such
reorganization,   consolidation   or  merger  or  the  effective  date  of  such
dissolution,  as the case may be,  shall  receive,  upon the proper and rightful
exercise  of this  Warrant,  in lieu of the Common  Stock (or Other  Securities)
issuable on such exercise prior to such consummation or such effective date, the
stock and other  securities and property  (including  cash) to which such holder
would have been  entitled  upon such  consummation  or in  connection  with such
dissolution,  as the case may be, if such holder had so exercised  this Warrant,
immediately  prior  thereto,  all subject to further  adjustment  thereafter  as
provided in Sections 4 and 5.

                  3.2.  CONTINUATION OF TERMS. Upon any corporate event referred
to in this Section 3, this Warrant  shall  continue in full force and effect and
the terms hereof shall be applicable to the shares of stock and Other Securities
and property  receivable on the exercise of this Warrant after the  consummation
of such  reorganization,  consolidation or merger, as the case may be, and shall
be binding upon the issuer of any such stock or other securities.

         4. ADJUSTMENTS FOR STOCK DIVIDENDS AND STOCK SPLITS.  In the event that
the Company shall (i) issue additional  shares of the Common Stock as a dividend
or  other   distribution  on  outstanding   Common  Stock,  (ii)  subdivide  its
outstanding  shares of Common Stock, or (iii) combine its outstanding  shares of
the Common Stock into a smaller  number of shares of the Common Stock,  then, in
each such event, the Exercise Price shall,  simultaneously with the happening of
such event, be adjusted by multiplying  the then prevailing  Exercise Price by a
fraction,  the  numerator of which shall be the number of shares of Common Stock
outstanding  immediately prior to such event (calculated assuming the conversion
or exchange of all outstanding shares of convertible or exchangeable  securities
of the Company which are convertible or exchangeable  into, or exercisable  for,
shares of Common  Stock)  and the  denominator  of which  shall be the number of
shares of Common  Stock  outstanding  immediately  after such event  (calculated
assuming the conversion or exchange of all outstanding  shares of convertible or
exchangeable  securities of the Company which are  convertible  or  exchangeable
into, or exercisable  for, shares of Common Stock),  and the product so obtained
shall thereafter be the Exercise Price then in effect. The Exercise Price, as so
adjusted,  shall be  readjusted  in the same  manner upon the  happening  of any
successive  event or events  described  herein in this  Section 4. The holder of
this Warrant shall thereafter,  on the exercise hereof as provided in Section 1,
be  entitled  to receive  that number of shares of Common  Stock  determined  by
multiplying  the number of shares of Common Stock which would otherwise (but for
the provisions of this Section 4) be issuable on such exercise, by a fraction of
which (i) the numerator is the Exercise Price which would otherwise (but for the
provisions  of this  Section 4) be in effect,  and (ii) the  denominator  is the
Exercise Price in effect on the date of such exercise.






                                      -6-

         5.   ADJUSTMENT   FOR   DIVIDENDS   IN  OTHER   STOCK,   PROPERTY   AND
RECLASSIFICATIONS.  In case at any time or from  time to time,  the  holders  of
Common  Stock (or Other  Securities)  shall have  received,  or (on or after the
record date fixed for the  determination  of  stockholders  eligible to receive)
shall have become entitled to receive, without payment therefor,

         (a) other or additional  stock or other  securities or property  (other
than cash) by way of dividend, or

         (b)  other  or  additional   stock  or  other  securities  or  property
(including   cash)   by   way   of   spin-off,    split-up,    reclassification,
recapitalization, combination of shares or similar corporate rearrangement,

other than additional shares of Common Stock (or Other  Securities)  issued as a
stock dividend or in a stock-split (adjustments in respect of which, in the case
of Common Stock,  are provided for in Section 4), then and in each such case the
holder of this Warrant,  on the exercise  hereof as provided in Section 1, shall
be  entitled  to  receive  the  amount  of other or  additional  stock and other
securities and property  (including cash in the cases referred to in subdivision
(b) of this Section 5) which such holder would hold on the date of such exercise
if on the  date of  distribution  of such  other  or  additional  stock or other
securities  and  property,  or on the  record  date  fixed for  determining  the
shareholders  entitled  to  receive  such  other  or  additional  stock or other
securities and property, such holder had been the holder of record of the number
of  shares  of  Common  Stock  called  for on the face of this  Warrant  and had
thereafter, during the period from the date thereof to and including the date of
such exercise,  retained such shares and all such other or additional  stock and
other  securities  and  property  (including  cash in the cases  referred  to in
subdivision (b) of this Section 5) receivable by such holder as aforesaid during
such period,  giving effect to all adjustments  called for during such period by
Sections 3 and 4.

         6.       NOTICES OF RECORD DATE.  In the event of

         (a) any taking by the  Company of a record of the  holders of any class
or  securities  for the  purpose of  determining  the  holders  thereof  who are
entitled  to  receive  any  dividend  or  other  distribution,  or any  right to
subscribe for, purchase or otherwise acquire any shares of stock of any class or
any other securities or property, or to receive any other right, or

         (b) any capital  reorganization of the Company, any reclassification or
recapitalization  of the capital  stock of the Company or any transfer of all or
substantially all the assets of the Company to or consolidation or merger of the
Company with or into any other person, or

         (c) any voluntary or involuntary dissolution, liquidation or winding-up
of the Company,

then and in each such event the  Company  will mail or cause to be mailed to the
holder of this Warrant a notice specifying (i) the date on which any such record
is to be taken for the  purpose of such  dividend,  distribution  or right,  and
stating the amount and character of such dividend,  distribution  or right,  and
(ii)   the   date  on   which   any   such   reorganization,   reclassification,







                                      -7-

recapitalization,  transfer, consolidation,  merger, dissolution, liquidation or
winding-up is to take place,  and the time,  if any is to be fixed,  as of which
the holders of record of Common Stock (or Other Securities) shall be entitled to
exchange  their shares of Common Stock (or Other  Securities)  for securities or
other   property   deliverable   on   such   reorganization,   reclassification,
recapitalization,  transfer, consolidation,  merger, dissolution, liquidation or
winding-up.  Such notice  shall be mailed at least twenty (20) days prior to the
date specified in such notice on which any such action is to be taken.

         7.  RESERVATION OF STOCK  ISSUABLE ON EXERCISE OF WARRANT.  The Company
will at all times reserve and keep  available,  solely for issuance and delivery
on the  exercise of the  Warrant,  all shares of Common  Stock from time to time
issuable on the  exercise of the  Warrant;  the shares of Common Stock which the
holder of this Warrant  shall  receive upon exercise of the Warrant will be duly
authorized, validly issued, fully paid and non-assessable.

         8.  EXCHANGE OF WARRANT.  On surrender  for  exchange of this  Warrant,
properly  endorsed,  to the  Company,  the Company at its expense will issue and
deliver to or on the order of the holder  thereof a new  Warrant or  Warrants of
like  tenor,  in the name of such  holder or as such  holder (on payment by such
holder of any applicable transfer taxes) may direct, calling in the aggregate on
the face or faces thereof for the number of shares of Common Stock called for on
the face or faces of the Warrant or Warrants so surrendered.

         9.   REPLACEMENT  OF  WARRANT.   On  receipt  of  evidence   reasonably
satisfactory  to the Company of the loss,  theft,  destruction  or mutilation of
this Warrant  and, in the case of any such loss,  theft or  destruction  of this
Warrant,   on  delivery  of  an  indemnity   agreement  or  security  reasonably
satisfactory  in form and  amount  to the  Company  or,  in the case of any such
mutilation,  on surrender and  cancellation of such Warrant,  the Company at its
expense will execute and deliver, in lieu thereof, a new Warrant of like tenor.

         10.  WARRANTHOLDER  NOT DEEMED  STOCKHOLDER;  RESTRICTIONS ON TRANSFER.
This Warrant is issued upon the following  terms, to all of which each holder or
owner hereof by the taking hereof consents and agrees:

         (a) No holder of this Warrant  shall,  as such, be deemed the holder of
      Common  Stock  that  may at any time be  issuable  upon  exercise  of this
      Warrant for any purpose whatsoever, nor shall anything contained herein be
      construed  to confer  upon such  holder,  as such,  any of the rights of a
      stockholder of the Company until such holder shall have  delivered  formal
      notice to the Company of an intention to exercise this  Warrant,  tendered
      promptly  the  consideration   required  for  exercise  (whether  cash  or
      securities), exercised the Warrant, and been issued shares of Common Stock
      in accordance with the provisions hereof.

         (b)  Neither  this  Warrant  nor any shares of Common  Stock  purchased
      pursuant to this Warrant shall be registered  under the  Securities Act of
      1933  (the  "SECURITIES   ACT")  and  applicable  state  securities  laws.
      Therefore,  the  Company may  require,  as a  condition  of  allowing  the
      transfer or exchange of this  Warrant or such  shares,  that the holder or
      transferee of this Warrant or such shares,  as the case may be, furnish to
      the Company an opinion of 






                                      -8-

      counsel  acceptable  to the  Company to the effect  that such  transfer or
      exchange may be made without  registration  under the  Securities  Act and
      applicable state  securities laws. The certificates  evidencing the shares
      of Common Stock issued on the exercise of the Warrant  shall bear a legend
      to the effect that the shares evidenced by such certificates have not been
      registered under the Securities Act and applicable state securities laws.

         (c) This Warrant is not transferable or assignable to any party without
      the prior written consent of the Company, and accompanied by an opinion of
      counsel  satisfactory  to the Company  that such  transfer is  permissible
      under applicable law.

         11. NOTICES.  All notices and other  communications from the Company to
the holder of this  Warrant  shall be mailed by (i) first  class  mail,  postage
prepaid,  (ii) electronic  facsimile  transmission,  or (iii) express  overnight
courier  service,  at such address as may have been  furnished to the Company in
writing by such  holder or,  until any such holder  furnishes  to the Company an
address, then to, and at the address of, the last holder of this Warrant who has
so furnished an address to the Company.

         12.  MISCELLANEOUS.  This  Warrant  and any term hereof may be changed,
waived,  discharged or terminated only by an instrument in writing signed by the
party against which enforcement of such change, waiver, discharge or termination
is sought.  This Warrant and the shares of Common Stock  underlying this Warrant
shall be construed and enforced in  accordance  with and governed by the laws of
the State of Delaware.  The  invalidity  or  unenforceability  of any  provision
hereof  shall in no way  affect  the  validity  or  enforceability  of any other
provision.

         13.      REGISTRATION RIGHTS.

                  13.1 SHORT-FORM REGISTRATIONS ON FORM S-3. At such time when a
510(k) or other  application has been filed for the BioLoc Technology or DynaGen
Technology and this Warrant is at least sixty percent (60%) vested in accordance
with  Section  1.3, at the request of the  holders of at least  seventy  percent
(70%) of the shares of Common Stock  underlying  this Warrant (the  "REGISTRABLE
SHARES"),  the  Company  shall  use its  best  efforts  to  file a  registration
statement  on Form S-3 (to the extent  such form is  available  to the  Company)
covering the resale of the Shares  underlying  this  Warrant  (the  "REGISTRABLE
SHARES").  The  Company  will so  notify  each  holder  of  Registrable  Shares,
including each holder who has a right to acquire  Registrable  Shares,  and then
shall, as expeditiously  as possible (using  commercially  reasonable  efforts),
effect  qualification  and registration  under the Securities Act on Form S-3 of
all or such  portion of the  Registrable  Shares as the holder or holders  shall
specify,  and shall thereafter  maintain the  effectiveness of such Registration
Statement until such shares have been sold or until the registration  obligation
terminates under Section 13.3.

         The  Company  shall  not be  required  to  effect  more  than  one  (1)
registration  on Form S-3. The  Company's  obligations  under this Section shall
expire  three (3) years after the  issuance  date of this  Warrant.  The Company
agrees to qualify or register the Shares under  applicable  state law,  list the
shares wherever the Common Stock is then listed and supplement the prospectus as
necessary from time to time to keep it current.





                                      -9-


                  13.2  EXPENSES.  In the case of a  registration  under Section
13.1,  the Company  shall bear the  expenses of any filing of any  registration,
including but not limited to printing legal and accounting expenses,  Securities
and Exchange Commission and NASD filing fees and all related "Blue Sky" fees and
expenses; provided, however, that the Company shall have no obligation to pay or
otherwise  bear  any  portion  of the  underwriters'  commissions  or  discounts
attributable  to the  securities  being  offered  and sold by the holder of this
Warrant,  or the fees and  expenses of any  counsel,  tax advisor or  accountant
selected by such holder in connection with the registration of the securities.

                  13.3 EXPIRATION OF REGISTRATION RIGHTS. The obligations of the
Company  under this  Section 13 to  register  the  securities  shall  expire and
terminate  at such  time as the  holder of this  Warrant  shall be  entitled  or
eligible to sell the shares of Common  Stock  underlying  this  Warrant  without
restriction and without a need for the filing of a registration  statement under
the Securities Act of 1933,  including  without  limitation,  for any resales of
restricted securities made pursuant to Rule 144 as promulgated by the Securities
and Exchange Commission.

                  13.4  DELAY OF  REGISTRATION.  For a period  not to exceed 120
days,  the Company  shall not be obligated to prepare and file,  or be prevented
from delaying or abandoning,  a registration  statement pursuant to this Section
13 at any time when the Company, in its good faith judgment by the management of
the Company, with the advice of counsel, reasonably believes:

                           (I) that the filing thereof at the time requested, or
the offering of  Registrable  Shares  pursuant  thereto,  would  materially  and
adversely affect (a) a pending or scheduled public offering or private placement
of the  Company's  securities,  (b) an  acquisition,  merger,  consolidation  or
similar  transaction  by or of the  Company,  (c)  pre-existing  and  continuing
negotiations,  discussions  or  pending  proposals  with  respect  to any of the
foregoing transactions, or (d) the financial condition of the Company in view of
the  disclosure of any pending or threatened  litigation,  claim,  assessment or
governmental investigation which may be required thereby; and

                           (II)  that  the  failure  to  disclose  any  material
information  with  respect  to the  foregoing  would  cause a  violation  of the
Securities Act or the Securities Exchange Act of 1934.

                  13.5  INDEMNIFICATION OF HOLDERS OF REGISTRABLE SHARES. In the
event  that the  Company  registers  any of the  Registrable  Shares  under  the
Securities  Act, the Company will  indemnify  and hold  harmless each holder and
each underwriter of the Registrable Shares (including their officers, directors,
affiliates  and partners) so registered  (including any broker or dealer through
whom such shares may be sold) and each person,  if any, who controls such holder
or any such  underwriter  within the meaning of Section 15 of the Securities Act
from and against any and all losses, claims,  damages,  expenses or liabilities,
joint  or  several,  to  which  they or any of them  become  subject  under  the
Securities Act,  applicable  state securities laws or under any other statute or
at common law or otherwise,  as incurred,  and, except as hereinafter  provided,
will reimburse each such holder, each such underwriter and each such controlling
person, if any, 






                                      -10-


for any legal or other  expenses  reasonably  incurred by them or any of them in
connection with  investigating or defending any actions whether or not resulting
in any liability, insofar as such losses, claims, damages, expenses, liabilities
or actions arise out of or are based upon any untrue statement or alleged untrue
statement of a material fact contained in the registration statement under which
such Securities were registered under the Securities Act, in any filing with any
state securities commission in any preliminary or amended preliminary prospectus
or in the final prospectus (or the registration  statement or prospectus as from
time to time amended or  supplemented  by the  Company),  or arise out of or are
based upon the  omission or alleged  omission to state  therein a material  fact
required  to be stated  therein  or  necessary  in order to make the  statements
therein,  in the  light  of the  circumstances  in which  they  were  made,  not
misleading,  or  any  violation  by  the  Company  of  any  rule  or  regulation
promulgated  under the Securities Act or any state securities laws applicable to
the  Company  and  relating  to action or  inaction  required  of the Company in
connection with such registration.

         Notwithstanding the foregoing,  the Company shall have no obligation to
indemnify  any holder,  underwriter  or  controlling  person if: (i) such untrue
statement or omission was made in such  registration  statement,  preliminary or
amended  preliminary  prospectus  or final  prospectus  in reliance  upon and in
conformity  with  information  furnished in writing to the Company in connection
therewith by such holder of Registrable  Shares (in the case of  indemnification
of such  holder),  such  underwriter  (in the  case of  indemnification  of such
underwriter) or such controlling  person (in the case of indemnification of such
controlling  person)  expressly  for use therein,  or (ii) in the case of a sale
directly  by  such  holder  of  Registrable  Shares  (including  a sale  of such
Registrable   Shares  through  any  underwriter   retained  by  such  holder  of
Registrable  Shares to engage in a distribution  solely on behalf of such holder
of Registrable  Shares),  such untrue  statement or alleged untrue  statement or
omission or alleged  omission was  contained  in a  preliminary  prospectus  and
corrected  in a final or amended  prospectus  copies of which were  delivered to
such holder of Registrable  Shares or such  underwriter  on a timely basis,  and
such  holder of  Registrable  Shares  failed  to  deliver a copy of the final or
amended  prospectus  at or  prior  to  the  confirmation  of  the  sale  of  the
Registrable  Shares to the  person  asserting  any such loss,  claim,  damage or
liability in any case where such delivery is required by the Securities Act.

         14. EXPIRATION. The right to exercise this Warrant shall expire at 5:00
p.m., Eastern Daylight Saving Time, on December 31, 2003.

                          COMMON STOCK PURCHASE WARRANT


         DYNAGEN, INC., a Delaware corporation (the "COMPANY"), hereby certifies
that,  in  consideration  of the  payment  of $100  (receipt  of which is hereby
acknowledged),  SHAWN BASU is entitled, subject to the terms set forth below, to

December 31, 2003, 18,000 fully paid and non-assessable  shares of Common Stock,
$.01 par value,  of the Company,  at an exercise price per share equal to $1.44.
Such exercise  price per share as adjusted from time to time as herein  provided
is referred to herein as the "EXERCISE PRICE".  The number and character of such
shares of Common  Stock and the  Exercise  Price are  subject to  adjustment  as
provided  herein.  THIS WARRANT IS EXERCISABLE IN  INSTALLMENTS,  SUBJECT TO THE
SATISFACTION OF CERTAIN CONDITIONS AS SET FORTH IN SECTION 1.3 BELOW. NO PORTION
OF THIS WARRANT MAY BE EXERCISED UNLESS SUCH CONDITIONS HAVE BEEN SATISFIED WITH
RESPECT TO THE CONDITIONS REGARDING EXERCISABILITY.

         As used  herein  the  following  terms,  unless the  context  otherwise
requires, have the following respective meanings:

         (a)  The  term  "COMPANY"  shall  include  DynaGen,  Inc.,  a  Delaware
corporation,  and any corporation  which shall succeed or assume the obligations
of the Company hereunder.

         (b) The term "COMMON  STOCK"  includes (a) the Company's  Common Stock,
$.01 par value per share,  as  authorized,  (b) any other  capital  stock of any
class or classes  (however  designated)  of the Company,  authorized on or after
such date, the holders of which shall have the





                                      -2-

right,  without  limitation  as to  amount,  either  to all or to a share of the
balance of current  dividends  and  liquidating  dividends  after the payment of
dividends  and  distributions  on any shares  entitled  to  preference,  and the
holders of which shall ordinarily, in the absence of contingencies,  be entitled
to vote for the election of a majority of directors of the Company  (even though
the right so to vote has been suspended by the happening of such a contingency),
(c) any other securities into which or for which any of the securities described
in  (a)  or  (b)  may  be  converted   or  exchanged   pursuant  to  a  plan  of
recapitalization,  reorganization,  merger, sale of assets or otherwise,  or the
conversion of promissory notes or other obligations of the Company.

         (c) The term "OTHER  SECURITIES" refers to any stock (other than Common
Stock) and other  securities  of the Company or any other person  (corporate  or
otherwise)  which the holder of this  Warrant at any time shall be  entitled  to
receive,  or shall have received,  on the exercise of the Warrant, in lieu of or
in  addition  to Common  Stock,  or which at any time shall be issuable or shall
have been  issued in exchange  for or in  replacement  of Common  Stock or Other
Securities pursuant to Sections 3 or 4 or otherwise.

         1.       EXERCISE OF WARRANT.

                  1.1. FULL  EXERCISE.  This Warrant may be exercised in full by
the holder hereof by surrender of this Warrant, with the form of subscription at
the end hereof duly  executed by such  holder,  to the Company at its  principal
office,  accompanied by payment,  in cash or by certified or official bank check
payable to the order of the Company,  in the amount  obtained by multiplying the
number of shares of Common Stock for which this Warrant is then  exercisable  by
the Exercise Price then in effect.

                  1.2. PARTIAL  EXERCISE.  This Warrant may be exercised in part
by surrender of this Warrant in the manner and at the place  provided in Section
1.1 except that the amount payable by the holder on such partial  exercise shall
be the amount  obtained by multiplying  (a) the number of shares of Common Stock
designated  by the  holder  in the  subscription  at the end  hereof  by (b) the
Exercise Price then in effect.  On any such partial  exercise the Company at its
expense  will  forthwith  issue and  deliver  to or upon the order of the holder
hereof a new Warrant or Warrants of like tenor, in the name of the holder hereof
or as such holder (upon payment by such holder of any applicable transfer taxes)
may  request,  calling in the  aggregate  on the face or faces  thereof  for the
number of shares of Common Stock for which such Warrant or Warrants may still be
exercised.

                  1.3  CONDITIONS  REGARDING  EXERCISABILITY.  Portions  of this
Warrant are exercisable  only upon the satisfaction of certain  conditions,  and
unlesss such  conditions  are  satisfied,  only that portion of this Warrant for
which the  conditions  have been  previously  satisfied  may be exercised at any
time.   The  Warrant  will  vest  and  become   exercisable   in  the  following
installments:  20% of the shares of Common  Stock under this  Warrant are vested
and exercisable upon delivery of the Warrant,  40% will become  exercisable upon
filing a 510(k)  or other  application  for the  BioLoc  Technology  or  DynaGen
Technology  with the FDA, and the  remaining  40% will become  exercisable  upon
approval of such  application  by the FDA;  provided,  however,  that the holder
continues to work on the BioLoc Technology or DynaGen  Technology and is engaged
by the Company as a consultant at the times of each of the foregoing milestones.
If the







                                      -3-

services  of the  holder of the  warrant  as a  consultant  to the  Company  are
terminated  without  cause,  then this  Warrant  shall  become  fully vested and
immediately  exercisable  at  the  time  of  any  FDA  application.  The  BioLoc
Technology  and DynaGen  Technology  is defined in a certain  Exclusive  License
Agreement  between the Company  and BioLoc,  Inc.  dated as of December 6, 1996.
DynaGen shall use  commercially  reasonable  efforts to file and prosecute  such
application with the FDA.

                  1.4 CASHLESS EXERCISE FEATURE -- RIGHT TO CONVERT WARRANT INTO
COMMON  STOCK.  (a) In  addition  to and  without  limiting  the  rights  of the
Warrantholder under the terms of this Warrant,  the Warrantholder shall have the
right (the  "CONVERSION  RIGHT") to convert this Warrant or any portion  thereof
into shares of Common Stock as provided in this Section at any time or from time
to time  prior to its  expiration,  subject  to the  restrictions  set  forth in
paragraph (c) hereof.  In lieu of exercising  this warrant for cash,  the holder
may elect to surrender  this  warrant for  conversion  and to receive  shares of
Common Stock equal to the value of this Warrant (or the portion being cancelled,
surrendered and converted) by surrender of this Warrant to the Company  together
with notice of such  election.  Upon such event,  the Company shall issue to the
holder a number of shares of the  Company's  Common Stock  computed by using the
following formula:
                        X  MINUS Y (A MINUS B)
                                        A
Where:            X = The  number of shares of Common  Stock to be issued to the
                      holder;  
                  Y = The number of shares of Common Stock  purchasable under
                      this  Warrant;  
                  A = The "Fair Market Value" of one share of the Common Stock; 
                      and 
                  B = The Exercise Price of the Warrant (as adjusted to the date
                      of the calculation).

         Upon  exercise of the  Conversion  Right with  respect to a  particular
number of shares  subject to this  Warrant,  the  Company  shall  deliver to the
Warrantholder, without payment by the Warrantholder of any exercise price or any
cash or other consideration,  that number of shares of Common Stock equal to the
number  computed  using  the above  formula.  Notwithstanding  anything  in this
Section to the contrary,  the Conversion  Right cannot be exercised with respect
to a number  of  Converted  Warrant  Shares  having  a value  below  $1,000.  No
fractional  shares shall be issuable upon exercised of the Conversion Right, and
if the number of shares to be issued in accordance with the foregoing formula is
other than a whole number,  the Company shall pay to the Warrantholder an amount
in cash equal to the Fair Market Value of the resulting fractional share.

         (b) The Conversion  Right may be exercised by the  Warrantholder by the
surrender of this Warrant at the principal office of the Company together with a
written statement specifying that the Warrantholder  thereby intends to exercise
the  Conversion  Right and  indicating  the number of shares of Common  Stock or
authorized  Common Stock subject to this Warrant which are being  surrendered in
exercise of the  Conversion  Right.  Such  conversion  shall be  effective  upon
receipt by the  Company of this  Warrant  together  with the  aforesaid  written
statement,  or on such  later  date as is  specified  therein  (the  "CONVERSION
DATE"), but not later than the expiration date of this Warrant.







                                      -4-

         (c) In the event the Conversion  Right would,  at any time this Warrant
remains  outstanding,  be deemed by the Company's  independent  certified public
accountants  to give rise to a charge to the  Company's  earnings for  financial
reporting purposes, then the Conversion Right shall automatically terminate upon
the Company's  written notice to the  Warrantholder  of such adverse  accounting
treatment.

         (d) For purposes of this Section, the "FAIR MARKET VALUE" of a share of
Common  Stock  or  authorized   Common  Stock  as  of  a  particular  date  (the
"DETERMINATION DATE") shall mean:

                  (i) if the  Company's  Common  Stock  is  then  traded  on any
nationally-recognized  stock  exchange or quoted on the NASDAQ  National  Market
System or  Small-Cap  Market,  the average of the closing sale prices for the 20
trading days preceding the  Determination  Date, as reported by such exchange or
system,  as  reported  in The Wall  Street  Journal  or any  other  publication,
including the NASD;

                  (ii) if the  Company's  Common  Stock  is then  traded  on the
over-the-counter market, the average of the closing bid and closing asked prices
for the 30 trading days  preceding  the  Determination  Date, as reported in The
Wall Street Journal or by any market maker; or

                  (iii)  if  quotations  for  the  Company's   Common  Stock  or
authorized  Common  Stock is not readily  available  as set forth in (i) or (ii)
above, then as determined in good faith by the Company's Board of Directors upon
a review of all relevant factors,  including,  without limitation,  the price at
which  shares of the  Company's  Common Stock or  authorized  Common Stock could
reasonably be expected to be sold in an arms-length transaction, for cash, other
than on an  installment  basis,  to a person not employed by,  controlled by, in
control of or under common control with the Company,  which determination by the
Board of Directors shall give due consideration to recent transactions involving
shares of the Common Stock or  authorized  Common  Stock,  if any,  revenues and
earnings of the Company to the date of such  determination  (if any),  projected
revenues and earnings of the Company, the effect of the transfer restrictions to
which the shares are subject  under law, the absence of a public  market for the
Common Stock or authorized  Common Stock, and such other matters as the Board of
Directors deems pertinent. Such determination by the Board of Directors shall be
conclusive and binding.

         2. DELIVERY OF STOCK  CERTIFICATES ON EXERCISE.  As soon as practicable
after the exercise of this  Warrant in full or in part,  and in any event within
thirty (30) days thereafter,  the Company at its expense  (including the payment
by it of any applicable  issue taxes) will cause to be issued in the name of and
delivered to the holder  hereof,  or as such holder (upon payment by such holder
of any applicable  transfer taxes) may direct, a certificate or certificates for
the number of fully  paid and  non-assessable  shares of Common  Stock (or Other
Securities)  to which such holder shall be entitled on such  exercise,  plus, in
lieu of any fractional  share to which such holder would  otherwise be entitled,
cash equal to such fraction  multiplied by the then current  market value of one
full share.

         3.       ADJUSTMENT FOR REORGANIZATION, CONSOLIDATION OR MERGER.

                  3.1.  REORGANIZATION,  CONSOLIDATION OR MERGER. In case at any
time or from time to time,  the Company shall (a) effect a  reorganization,  (b)
consolidate  with or merge into any other person or entity,  or (c) transfer all
or  substantially  all of its capital  stock,  properties or assets to any other
person  under  any plan or  arrangement  contemplating  the  dissolution  of the
Company,  then, in each such case,  the holder of this Warrant,  on the exercise
hereof as  provided  in  Section 1 at any time  after the  consummation  of such
reorganization,   consolidation   or  merger  or  the  effective  date  of  such
dissolution,  as the case may be,  shall  receive,  upon the proper and rightful
exercise  of this  Warrant,  in lieu of the Common  Stock (or Other  Securities)
issuable on such exercise prior to such consummation or such effective date, the
stock and other  securities and property  (including  cash) to which such holder
would have been  entitled  upon such  consummation  or in  connection  with such
dissolution,  as the case may be, if such holder had so exercised  this Warrant,
immediately  prior  thereto,  all subject to further  adjustment  thereafter  as
provided in Sections 4 and 5.

                  3.2.  CONTINUATION OF TERMS. Upon any corporate event referred
to in this Section 3, this Warrant  shall  continue in full force and effect and
the terms hereof shall be applicable to the shares of stock and Other Securities
and property  receivable on the exercise of this Warrant after the  consummation
of such  reorganization,  consolidation or merger, as the case may be, and shall
be binding upon the issuer of any such stock or other securities.

         4. ADJUSTMENTS FOR STOCK DIVIDENDS AND STOCK SPLITS.  In the event that
the Company shall (i) issue additional  shares of the Common Stock as a dividend
or  other   distribution  on  outstanding   Common  Stock,  (ii)  subdivide  its
outstanding  shares of Common Stock, or (iii) combine its outstanding  shares of
the Common Stock into a smaller  number of shares of the Common Stock,  then, in
each such event, the Exercise Price shall,  simultaneously with the happening of
such event, be adjusted by multiplying  the then prevailing  Exercise Price by a
fraction,  the  numerator of which shall be the number of shares of Common Stock
outstanding  immediately prior to such event (calculated assuming the conversion
or exchange of all outstanding shares of convertible or exchangeable  securities
of the Company which are convertible or exchangeable  into, or exercisable  for,
shares of Common  Stock)  and the  denominator  of which  shall be the number of
shares of Common  Stock  outstanding  immediately  after such event  (calculated
assuming the conversion or exchange of all outstanding  shares of convertible or
exchangeable  securities of the Company which are  convertible  or  exchangeable
into, or exercisable  for, shares of Common Stock),  and the product so obtained
shall thereafter be the Exercise Price then in effect. The Exercise Price, as so
adjusted,  shall be  readjusted  in the same  manner upon the  happening  of any
successive  event or events  described  herein in this  Section 4. The holder of
this Warrant shall thereafter,  on the exercise hereof as provided in Section 1,
be  entitled  to receive  that number of shares of Common  Stock  determined  by
multiplying  the number of shares of Common Stock which would otherwise (but for
the provisions of this Section 4) be issuable on such exercise, by a fraction of
which (i) the numerator is the Exercise Price which would otherwise (but for the
provisions  of this  Section 4) be in effect,  and (ii) the  denominator  is the
Exercise Price in effect on the date of such exercise.







                                      -6-

         5.   ADJUSTMENT   FOR   DIVIDENDS   IN  OTHER   STOCK,   PROPERTY   AND
RECLASSIFICATIONS.  In case at any time or from  time to time,  the  holders  of
Common  Stock (or Other  Securities)  shall have  received,  or (on or after the
record date fixed for the  determination  of  stockholders  eligible to receive)
shall have become entitled to receive, without payment therefor,

         (a) other or additional  stock or other  securities or property  (other
than cash) by way of dividend, or

         (b)  other  or  additional   stock  or  other  securities  or  property
(including   cash)   by   way   of   spin-off,    split-up,    reclassification,
recapitalization, combination of shares or similar corporate rearrangement,

other than additional shares of Common Stock (or Other  Securities)  issued as a
stock dividend or in a stock-split (adjustments in respect of which, in the case
of Common Stock,  are provided for in Section 4), then and in each such case the
holder of this Warrant,  on the exercise  hereof as provided in Section 1, shall
be  entitled  to  receive  the  amount  of other or  additional  stock and other
securities and property  (including cash in the cases referred to in subdivision
(b) of this Section 5) which such holder would hold on the date of such exercise
if on the  date of  distribution  of such  other  or  additional  stock or other
securities  and  property,  or on the  record  date  fixed for  determining  the
shareholders  entitled  to  receive  such  other  or  additional  stock or other
securities and property, such holder had been the holder of record of the number
of  shares  of  Common  Stock  called  for on the face of this  Warrant  and had
thereafter, during the period from the date thereof to and including the date of
such exercise,  retained such shares and all such other or additional  stock and
other  securities  and  property  (including  cash in the cases  referred  to in
subdivision (b) of this Section 5) receivable by such holder as aforesaid during
such period,  giving effect to all adjustments  called for during such period by
Sections 3 and 4.

         6.       NOTICES OF RECORD DATE.  In the event of

         (a) any taking by the  Company of a record of the  holders of any class
or  securities  for the  purpose of  determining  the  holders  thereof  who are
entitled  to  receive  any  dividend  or  other  distribution,  or any  right to
subscribe for, purchase or otherwise acquire any shares of stock of any class or
any other securities or property, or to receive any other right, or

         (b) any capital  reorganization of the Company, any reclassification or
recapitalization  of the capital  stock of the Company or any transfer of all or
substantially all the assets of the Company to or consolidation or merger of the
Company with or into any other person, or

         (c) any voluntary or involuntary dissolution, liquidation or winding-up
of the Company,

then and in each such event the  Company  will mail or cause to be mailed to the
holder of this Warrant a notice specifying (i) the date on which any such record
is to be taken for the  purpose of such  dividend,  distribution  or right,  and
stating the amount and character of such dividend,  distribution  or right,  and
(ii)   the   date  on   which   any   such   reorganization,   reclassification,






                                      -7-

recapitalization,  transfer, consolidation,  merger, dissolution, liquidation or
winding-up is to take place,  and the time,  if any is to be fixed,  as of which
the holders of record of Common Stock (or Other Securities) shall be entitled to
exchange  their shares of Common Stock (or Other  Securities)  for securities or
other   property   deliverable   on   such   reorganization,   reclassification,
recapitalization,  transfer, consolidation,  merger, dissolution, liquidation or
winding-up.  Such notice  shall be mailed at least twenty (20) days prior to the
date specified in such notice on which any such action is to be taken.

         7.  RESERVATION OF STOCK  ISSUABLE ON EXERCISE OF WARRANT.  The Company
will at all times reserve and keep  available,  solely for issuance and delivery
on the  exercise of the  Warrant,  all shares of Common  Stock from time to time
issuable on the  exercise of the  Warrant;  the shares of Common Stock which the
holder of this Warrant  shall  receive upon exercise of the Warrant will be duly
authorized, validly issued, fully paid and non-assessable.

         8.  EXCHANGE OF WARRANT.  On surrender  for  exchange of this  Warrant,
properly  endorsed,  to the  Company,  the Company at its expense will issue and
deliver to or on the order of the holder  thereof a new  Warrant or  Warrants of
like  tenor,  in the name of such  holder or as such  holder (on payment by such
holder of any applicable transfer taxes) may direct, calling in the aggregate on
the face or faces thereof for the number of shares of Common Stock called for on
the face or faces of the Warrant or Warrants so surrendered.

         9.   REPLACEMENT  OF  WARRANT.   On  receipt  of  evidence   reasonably
satisfactory  to the Company of the loss,  theft,  destruction  or mutilation of
this Warrant  and, in the case of any such loss,  theft or  destruction  of this
Warrant,   on  delivery  of  an  indemnity   agreement  or  security  reasonably
satisfactory  in form and  amount  to the  Company  or,  in the case of any such
mutilation,  on surrender and  cancellation of such Warrant,  the Company at its
expense will execute and deliver, in lieu thereof, a new Warrant of like tenor.

         10.  WARRANTHOLDER  NOT DEEMED  STOCKHOLDER;  RESTRICTIONS ON TRANSFER.
This Warrant is issued upon the following  terms, to all of which each holder or
owner hereof by the taking hereof consents and agrees:

         (a) No holder of this Warrant  shall,  as such, be deemed the holder of
      Common  Stock  that  may at any time be  issuable  upon  exercise  of this
      Warrant for any purpose whatsoever, nor shall anything contained herein be
      construed  to confer  upon such  holder,  as such,  any of the rights of a
      stockholder of the Company until such holder shall have  delivered  formal
      notice to the Company of an intention to exercise this  Warrant,  tendered
      promptly  the  consideration   required  for  exercise  (whether  cash  or
      securities), exercised the Warrant, and been issued shares of Common Stock
      in accordance with the provisions hereof.

         (b)  Neither  this  Warrant  nor any shares of Common  Stock  purchased
      pursuant to this Warrant shall be registered  under the  Securities Act of
      1933  (the  "SECURITIES   ACT")  and  applicable  state  securities  laws.
      Therefore,  the  Company may  require,  as a  condition  of  allowing  the
      transfer or exchange of this  Warrant or such  shares,  that the holder or
      transferee of this Warrant or such shares,  as the case may be, furnish to
      the Company an opinion of






                                      -8-

      counsel  acceptable  to the  Company to the effect  that such  transfer or
      exchange may be made without  registration  under the  Securities  Act and
      applicable state  securities laws. The certificates  evidencing the shares
      of Common Stock issued on the exercise of the Warrant  shall bear a legend
      to the effect that the shares evidenced by such certificates have not been
      registered under the Securities Act and applicable state securities laws.

         (c) This Warrant is not transferable or assignable to any party without
      the prior written consent of the Company, and accompanied by an opinion of
      counsel  satisfactory  to the Company  that such  transfer is  permissible
      under applicable law.

         11. NOTICES.  All notices and other  communications from the Company to
the holder of this  Warrant  shall be mailed by (i) first  class  mail,  postage
prepaid,  (ii) electronic  facsimile  transmission,  or (iii) express  overnight
courier  service,  at such address as may have been  furnished to the Company in
writing by such  holder or,  until any such holder  furnishes  to the Company an
address, then to, and at the address of, the last holder of this Warrant who has
so furnished an address to the Company.

         12.  MISCELLANEOUS.  This  Warrant  and any term hereof may be changed,
waived,  discharged or terminated only by an instrument in writing signed by the
party against which enforcement of such change, waiver, discharge or termination
is sought.  This Warrant and the shares of Common Stock  underlying this Warrant
shall be construed and enforced in  accordance  with and governed by the laws of
the State of Delaware.  The  invalidity  or  unenforceability  of any  provision
hereof  shall in no way  affect  the  validity  or  enforceability  of any other
provision.

         13.      REGISTRATION RIGHTS.

                  13.1 SHORT-FORM REGISTRATIONS ON FORM S-3. At such time when a
510(k) or other  application has been filed for the BioLoc Technology or DynaGen
Technology and this Warrant is at least sixty percent (60%) vested in accordance
with  Section  1.3, at the request of the  holders of at least  seventy  percent
(70%) of the shares of Common Stock  underlying  this Warrant (the  "REGISTRABLE
SHARES"),  the  Company  shall  use its  best  efforts  to  file a  registration
statement  on Form S-3 (to the extent  such form is  available  to the  Company)
covering the resale of the Shares  underlying  this  Warrant  (the  "REGISTRABLE
SHARES").  The  Company  will so  notify  each  holder  of  Registrable  Shares,
including each holder who has a right to acquire  Registrable  Shares,  and then
shall, as expeditiously  as possible (using  commercially  reasonable  efforts),
effect  qualification  and registration  under the Securities Act on Form S-3 of
all or such  portion of the  Registrable  Shares as the holder or holders  shall
specify,  and shall thereafter  maintain the  effectiveness of such Registration
Statement until such shares have been sold or until the registration  obligation
terminates under Section 13.3.

         The  Company  shall  not be  required  to  effect  more  than  one  (1)
registration  on Form S-3. The  Company's  obligations  under this Section shall
expire  three (3) years after the  issuance  date of this  Warrant.  The Company
agrees to qualify or register the Shares under  applicable  state law,  list the
shares wherever the Common Stock is then listed and supplement the prospectus as
necessary from time to time to keep it current.





                                      -9-

                  13.2  EXPENSES.  In the case of a  registration  under Section
13.1,  the Company  shall bear the  expenses of any filing of any  registration,
including but not limited to printing legal and accounting expenses,  Securities
and Exchange Commission and NASD filing fees and all related "Blue Sky" fees and
expenses; provided, however, that the Company shall have no obligation to pay or
otherwise  bear  any  portion  of the  underwriters'  commissions  or  discounts
attributable  to the  securities  being  offered  and sold by the holder of this
Warrant,  or the fees and  expenses of any  counsel,  tax advisor or  accountant
selected by such holder in connection with the registration of the securities.

                  13.3 EXPIRATION OF REGISTRATION RIGHTS. The obligations of the
Company  under this  Section 13 to  register  the  securities  shall  expire and
terminate  at such  time as the  holder of this  Warrant  shall be  entitled  or
eligible to sell the shares of Common  Stock  underlying  this  Warrant  without
restriction and without a need for the filing of a registration  statement under
the Securities Act of 1933,  including  without  limitation,  for any resales of
restricted securities made pursuant to Rule 144 as promulgated by the Securities
and Exchange Commission.

                  13.4  DELAY OF  REGISTRATION.  For a period  not to exceed 120
days,  the Company  shall not be obligated to prepare and file,  or be prevented
from delaying or abandoning,  a registration  statement pursuant to this Section
13 at any time when the Company, in its good faith judgment by the management of
the Company, with the advice of counsel, reasonably believes:

                           (I) that the filing thereof at the time requested, or
the offering of  Registrable  Shares  pursuant  thereto,  would  materially  and
adversely affect (a) a pending or scheduled public offering or private placement
of the  Company's  securities,  (b) an  acquisition,  merger,  consolidation  or
similar  transaction  by or of the  Company,  (c)  pre-existing  and  continuing
negotiations,  discussions  or  pending  proposals  with  respect  to any of the
foregoing transactions, or (d) the financial condition of the Company in view of
the  disclosure of any pending or threatened  litigation,  claim,  assessment or
governmental investigation which may be required thereby; and

                           (II)  that  the  failure  to  disclose  any  material
information  with  respect  to the  foregoing  would  cause a  violation  of the
Securities Act or the Securities Exchange Act of 1934.

                  13.5  INDEMNIFICATION OF HOLDERS OF REGISTRABLE SHARES. In the
event  that the  Company  registers  any of the  Registrable  Shares  under  the
Securities  Act, the Company will  indemnify  and hold  harmless each holder and
each underwriter of the Registrable Shares (including their officers, directors,
affiliates  and partners) so registered  (including any broker or dealer through
whom such shares may be sold) and each person,  if any, who controls such holder
or any such  underwriter  within the meaning of Section 15 of the Securities Act
from and against any and all losses, claims,  damages,  expenses or liabilities,
joint  or  several,  to  which  they or any of them  become  subject  under  the
Securities Act,  applicable  state securities laws or under any other statute or
at common law or otherwise,  as incurred,  and, except as hereinafter  provided,
will reimburse each such holder, each such underwriter and each such controlling
person, if any, 







                                      -10-

for any legal or other  expenses  reasonably  incurred by them or any of them in
connection with  investigating or defending any actions whether or not resulting
in any liability, insofar as such losses, claims, damages, expenses, liabilities
or actions arise out of or are based upon any untrue statement or alleged untrue
statement of a material fact contained in the registration statement under which
such Securities were registered under the Securities Act, in any filing with any
state securities commission in any preliminary or amended preliminary prospectus
or in the final prospectus (or the registration  statement or prospectus as from
time to time amended or  supplemented  by the  Company),  or arise out of or are
based upon the  omission or alleged  omission to state  therein a material  fact
required  to be stated  therein  or  necessary  in order to make the  statements
therein,  in the  light  of the  circumstances  in which  they  were  made,  not
misleading,  or  any  violation  by  the  Company  of  any  rule  or  regulation
promulgated  under the Securities Act or any state securities laws applicable to
the  Company  and  relating  to action or  inaction  required  of the Company in
connection with such registration.

         Notwithstanding the foregoing,  the Company shall have no obligation to
indemnify  any holder,  underwriter  or  controlling  person if: (i) such untrue
statement or omission was made in such  registration  statement,  preliminary or
amended  preliminary  prospectus  or final  prospectus  in reliance  upon and in
conformity  with  information  furnished in writing to the Company in connection
therewith by such holder of Registrable  Shares (in the case of  indemnification
of such  holder),  such  underwriter  (in the  case of  indemnification  of such
underwriter) or such controlling  person (in the case of indemnification of such
controlling  person)  expressly  for use therein,  or (ii) in the case of a sale
directly  by  such  holder  of  Registrable  Shares  (including  a sale  of such
Registrable   Shares  through  any  underwriter   retained  by  such  holder  of
Registrable  Shares to engage in a distribution  solely on behalf of such holder
of Registrable  Shares),  such untrue  statement or alleged untrue  statement or
omission or alleged  omission was  contained  in a  preliminary  prospectus  and
corrected  in a final or amended  prospectus  copies of which were  delivered to
such holder of Registrable  Shares or such  underwriter  on a timely basis,  and
such  holder of  Registrable  Shares  failed  to  deliver a copy of the final or
amended  prospectus  at or  prior  to  the  confirmation  of  the  sale  of  the
Registrable  Shares to the  person  asserting  any such loss,  claim,  damage or
liability in any case where such delivery is required by the Securities Act.

         14. EXPIRATION. The right to exercise this Warrant shall expire at 5:00
p.m., Eastern Daylight Saving Time, on December 31, 2003.

               (except as otherwise set forth in Section 2 below)


         1. Issuance.  This Warrant is issued to Leonardo G. Zangani by DynaGen,
Inc.,  a  Delaware  corporation  (hereinafter  with its  successors  called  the
"Company").  THIS  WARRANT  IS  EXERCISABLE  IN  INSTALLMENTS,  SUBJECT  TO  THE
SATISFACTION  OF CERTAIN  CONDITIONS AS SET FORTH IN SECTION 2 BELOW. NO PORTION
OF THIS WARRANT MAY BE EXERCISED UNLESS SUCH CONDITIONS HAVE BEEN SATISFIED WITH
RESPECT TO THE CONDITIONS REGARDING EXERCISABILITY.

         2.  Purchase  Price;  Number  of  Shares.  Subject  to  the  terms  and
conditions  hereinafter  set forth,  the registered  holder of this Warrant (the
"Holder") is entitled upon surrender of this Warrant with the subscription  form
annexed  hereto duly  executed,  at the office of the  Company,  99 Erie Street,
Cambridge, Massachusetts 02139, or such other office as the Company shall notify
the Holder of in writing, to purchase from the Company at a price per share (the
"Purchase  Price") of $1.97 an aggregate of fifty  thousand  (50,000) fully paid
and  nonassessable  shares of Common Stock,  $.01 par value, of the Company (the
"Common Stock"),  subject to the conditions stated immediately below. Commencing
on the date  hereof,  the Holder may  exercise  this  Warrant for 25,000 of such
shares.  If, within six months of the date hereof, the Company renews or extends
the  original  term of the  Consulting  Agreement  between  the Company and L.G.
Zangani, Inc. (the "Agreement"), then, commencing on the date that is six months
from the date  hereof,  the Holder may exercise  this Warrant for the  remaining
shares of Common Stock subject  hereto.  If the Company does not renew or extend
the original  term of the Agreement  within six months of the date hereof,  such
remaining  shares  shall not be  exercisable,  and the  portion  of the  Warrant
relating  to  such  remaining  shares  shall  be   automatically   canceled  and
extinguished  and shall be without further effect.  Furthermore,  if the Company
does not renew or extend the original  term of the  Agreement  within six months
hereof,  notwithstanding  anything to the contrary  herein,  this Warrant  shall

thereafter. Until such time as this Warrant is exercised in full or expires, the
Purchase  Price and the  securities  issuable  upon exercise of this Warrant are
subject to adjustment as hereinafter provided.





                                      -2-

         3. Payment of Purchase  Price.  Except as set forth in Section 4 below,
the Purchase Price shall be paid in cash or by check.

         4. Net Issue  Election.  The Holder may elect to  receive,  without the
payment by the Holder of any additional consideration, shares equal to the value
of this Warrant or any portion  hereof by the  surrender of this Warrant or such
portion to the Company,  with the net issue election  notice annexed hereto duly
executed,  at the office of the Company.  Thereupon,  the Company shall issue to
the Holder such number of fully paid and nonassessable shares of Common Stock as
is computed using the following formula:

                                   X = Y (A-B)
                                           A

where             X =      the number of shares to be issued to the Holder 
                           pursuant to this Section 4.

                  Y =      the number of shares covered by this Warrant, subject
                           to  Section 2  hereof,  in  respect  of which the net
                           issue election is made pursuant to this Section 4.

                  A =      The "Fair Market Value" of one share of Common Stock.

                  B =      the  Purchase  Price in effect  under this Warrant at
                           the time the net issue  election is made  pursuant to
                           this Section 4.

         For purposes of this  Section 4, the "Fair Market  Value" of a share of
Common Stock as of a particular date (the "Determination Date") means:

                  (i) if the  Company's  Common  Stock  is  then  traded  on any
nationally  recognized  stock exchange or quoted on the Nasdaq  National  Market
System or SmallCap  Market,  the  average of the closing  sale prices for the 10
trading days preceding the  Determination  Date, as reported by such exchange or
system,  as  reported  in The Wall  Street  Journal  or any  other  publication,
including the NASD;

                  (ii) if the  Company's  Common  Stock  is then  traded  on the
over-the-counter market, the average of the closing bid and closing asked prices
for the 15 trading days  preceding  the  Determination  Date, as reported in The
Wall Street Journal or by any market maker; or

                  (iii) if  quotations  for the  Company's  Common Stock are not
readily  available as set forth in (i) or (ii) above, then as determined in good
faith by the Company's Board of Directors upon a review of all relevant factors,
including, without limitation, the price at which shares of the Company's Common
Stock could reasonably be expected to be sold in an arms-length transaction, for
cash,  other  than  on an  installment  basis,  to a  person  not  employed  by,
controlled  by, in control of or under common  control  with the Company,  which
determination  by the Board of Directors shall give due  consideration to recent
transactions involving shares of 





                                      -3-

the Common  Stock,  if any,  revenues and earnings of the Company to the date of
such determination,  if any, projected revenues and earnings of the Company, the
effect of the transfer  restrictions  to which the shares are subject under law,
the absence of a public market for the Common  Stock,  and such other matters as
the Board of  Directors  deems  pertinent.  Such  determination  by the Board of
Directors shall be conclusive and binding.

         5. Partial  Exercise.  This  Warrant may be exercised in part,  and the
Holder  shall be entitled to receive a new  warrant,  which shall be dated as of
the date of this Warrant, covering the number of shares in respect of which this
Warrant shall not have been exercised.

         6.  Issuance  Date.  The  person or  persons in whose name or names any
certificate  representing  shares of Common Stock is issued  hereunder  shall be
deemed to have become the holder of record of the shares represented  thereby as
at the close of business on the date this Warrant is  exercised  with respect to
such shares, whether or not the transfer books of the Company shall be closed.

         7. Expiration  Date. This Warrant shall expire at the close of business
on January 15, 2002 (unless it expires earlier under Section 2 hereof) and shall
be void thereafter.

         8. Reserved Shares; Valid Issuance.  The Company covenants that it will
at all times from and after the date  hereof  reserve  and keep  available  such
number of its  authorized  shares of Common Stock,  free from all  preemptive or
similar  rights  therein,  as will be  sufficient to permit the exercise of this
Warrant in full. The Company further covenants that such shares as may be issued
pursuant to the  exercise  of this  Warrant  will,  upon  issuance,  be duly and
validly issued,  fully paid and nonassessable and free from all taxes, liens and
charges with respect to the issuance thereof.

         9.  Registration  Rights.  The  Company  hereby  grants  the  following
registration  rights with respect to the shares covered by this Warrant (subject
to Section 2 hereof):

                  9.1  "Piggy-Back"  Registrations.  If at any time the  Company
shall  determine  to  register in a public  offering  for the account of selling
stockholders  (and not for its own account) under the Securities Act of 1933, as
amended,  any of its Common Stock, it shall send to the Holder written notice of
such  determination  and, if within 15 days after  receipt of such  notice,  the
Holder  shall so request in writing,  the Company  shall use its best efforts to
include in such registration  statement all or any part of the shares covered by
this Warrant  that the Holder  requests to be  registered.  This right shall not
apply to a  registration  of shares of Common  Stock on Form S-8 or Form S-4 (or
their then  equivalents)  relating to shares of Common Stock to be issued by the
Company in connection  with any  acquisition of any entity or business or shares
of Common Stock issuable in connection with any stock option,  stock purchase or
other employee  benefit plan.  Notwithstanding  anything to the contrary in this
Section 9, the Company shall not be required to effect a  registration  pursuant
to this Section 9 for fewer than the total  number of shares  issuable or issued
pursuant  to this  Warrant  (as set forth in  Section  2 hereof)  at the time of
filing of such registration statement.





                                      -4-

                           If, in  connection  with any offering of Common Stock
to be sold by selling  stockholders,  the  managing  underwriter  or the Company
shall  impose a  limitation  on the number of shares of Common Stock that may be
included in any such  registration  statement  because,  in its  judgment,  such
limitation is necessary to effect an orderly public  distribution  of the Common
Stock and to maintain a stable market for the equity  securities of the Company,
then the Company  shall be obligated to include in such  registration  statement
only such limited  portion of the shares covered by this Warrant with respect to
which the Holder has requested inclusion hereunder.

                  9.2 Expenses. In the case of a registration under this Section
9, the  Company  shall bear all costs and  expenses  of each such  registration,
including,  but  not  limited  to,  printing,  legal  and  accounting  expenses,
Securities  and Exchange  Commission  and  National  Association  of  Securities
Dealers  filing fees and all  related  "Blue Sky" fees and  expenses;  provided,
however,  that the Company shall have no obligation to pay or otherwise bear any
portion of the underwriters' commissions or discounts attributable to the shares
covered by this Warrant  being  offered and sold by the Holder,  or the fees and
expenses of any counsel for the Holder in connection  with the  registration  of
such shares.

                  9.3 Expiration of Registration  Rights. The obligations of the
Company  under  this  Section 9 shall  expire on the  earlier of (i) the date on
which the shares covered by this Warrant shall have become transferable (whether
or not so transferred) in accordance with the resale  provisions of Rule 144, or
any successor  rule or provision,  under the Securities Act of 1933, as amended,
and (ii) the date that this Warrant terminates.

         10. Dividends. If after the date hereof the Company shall subdivide the
Common Stock,  by split-up or otherwise,  or combine the Common Stock,  or issue
additional  shares of Common Stock in payment of a stock  dividend on the Common
Stock,  the number of shares  issuable  on the  exercise of this  Warrant  shall
forthwith be  proportionately  increased in the case of a  subdivision  or stock
dividend,  or  proportionately  decreased in the case of a combination,  and the
Purchase  Price shall  forthwith be  proportionately  decreased in the case of a
subdivision or stock  dividend,  or  proportionately  increased in the case of a
combination.

         11. Mergers and Reclassifications. If after the date hereof there shall
be any  reclassification,  capital  reorganization or change of the Common Stock
(other than as a result of a subdivision, combination or stock dividend provided
for in Section 10 hereof),  or any  consolidation of the Company with, or merger
of the Company into, another  corporation or other business  organization (other
than  a  consolidation  or  merger  in  which  the  Company  is  the  continuing
corporation and which does not result in any  reclassification  or change of the
outstanding  Common Stock), or any sale or conveyance to another  corporation or
other business  organization  of all or  substantially  all of the assets of the
Company (each an "Acquisition Event"),  then, as a condition of such Acquisition
Event,  lawful provisions shall be made, and duly executed documents  evidencing
the same from the Company or its successor shall be delivered to the Holder,  so
that the Holder shall have the right to purchase, at a total price not to exceed
that payable  upon the exercise of this Warrant in full,  the kind and amount of
shares  of  stock  and  other  securities  and  property  receivable  upon  such
Acquisition  Event by a holder of the 






                                      -5-

number of shares of Common  Stock which might have been  purchased by the Holder
immediately  prior to such  Acquisition  Event, and in any such case appropriate
provisions  shall be made with  respect to the rights and interest of the Holder
to the end that the provisions hereof (including without limitation,  provisions
for the  adjustment  of the  Purchase  Price and the  number of shares  issuable
hereunder)  shall thereafter be applicable in relation to any shares of stock or
other securities and property thereafter deliverable upon exercise hereof.

         Notwithstanding  anything  to the  contrary  herein,  the  Holder  must
exercise this Warrant prior to the consummation of the Acquisition Event, and if
this Warrant is not so exercised,  it shall  terminate upon the  consummation of
such Acquisition Event.

         12. Fractional Shares. In no event shall any fractional share of Common
Stock be issued upon any  exercise of this  Warrant.  If, upon  exercise of this
Warrant as an entirety, the Holder would, except as provided in this Section 12,
be  entitled to receive a  fractional  share of Common  Stock,  then the Company
shall issue the next higher  number of full  shares of Common  Stock,  issuing a
full share with respect to such fractional share.

         13. Certificate of Adjustment. Whenever the Purchase Price is adjusted,
as  herein  provided,  the  Company  shall  promptly  deliver  to the  Holder  a
certificate  of the  principal  financial or  accounting  officer of the Company
setting forth the Purchase Price after such adjustment and setting forth a brief
statement of the facts requiring such adjustment.

         14.      Notices of Record Date, Etc.  In the event of:

                  (a) any taking by the  Company  of a record of the  holders of
any class of securities for the purpose of determining  the holders  thereof who
are  entitled to receive any  dividend  or other  distribution,  or any right to
subscribe for, purchase or otherwise acquire any shares of stock of any class or
any other securities or property, or to receive any other right,

                  (b) any  reclassification of the capital stock of the Company,
capital  reorganization  of the Company,  consolidation  or merger involving the
Company, or sale or conveyance of all or substantially all of its assets, or

                  (c) any voluntary or involuntary  dissolution,  liquidation or
winding-up of the Company,

then and in each such event the  Company  will mail or cause to be mailed to the
Holder a notice  specifying (i) the date on which any such record is to be taken
for the purpose of such dividend,  distribution or right, and stating the amount
and character of such dividend, distribution or right, or (ii) the date on which
any  such  reclassification,  reorganization,  consolidation,  merger,  sale  or
conveyance,  dissolution,  liquidation  or winding-up is to take place,  and the
time,  if any is to be fixed,  as of which the  holders  of record in respect of
such event are to be  determined.  Such notice  shall be mailed at least 20 days
prior to the date  specified  in such  notice on which any such  action is to be
taken.





                                      -6-

         15.  Amendment.  The terms of this Warrant may be amended,  modified or
waived only with the written consent of the Company.

         16.  Warrant  Register;   Transfers,  Etc.;  Warrantholder  Not  Deemed
Stockholder.

                  A. The Company will  maintain a register  containing  the name
and  address of the  Holder and its  assignees,  if  applicable.  The Holder may
change its  address as shown on the warrant  register  by written  notice to the
Company requesting such change. Any notice or written communication  required or
permitted to be given to the Holder may be given by certified  mail or delivered
to the Holder at its address as shown on the warrant register.

                  B.  Without the prior  written  consent of the  Company,  this
Warrant may not be transferred by the Holder.

                  C. In case this Warrant  shall be mutilated,  lost,  stolen or
destroyed,  the Company shall issue a new warrant of like tenor and denomination
and deliver the same (i) in exchange and substitution for and upon surrender and
cancellation  of any  mutilated  Warrant,  or (ii) in lieu of any Warrant  lost,
stolen or destroyed,  upon receipt of evidence  reasonably  satisfactory  to the
Company  of the  loss,  theft  or  destruction  of  such  Warrant  (including  a
reasonably  detailed  affidavit with respect to the  circumstances  of any loss,
theft or destruction) and of indemnity reasonably satisfactory to the Company.

                  D. No holder of this  Warrant  shall,  as such,  be deemed the
holder of the Common  Stock that may at any time be  issuable  upon  exercise of
this Warrant for any purpose whatsoever,  nor shall anything contained herein be
construed  to  confer  upon  such  holder,  as  such,  any  of the  rights  of a
stockholder of the Company until such holder has delivered  formal notice to the
Company  of an  intention  to  exercise  this  Warrant,  tendered  promptly  the
consideration required for exercise (whether cash or securities),  exercised the
Warrant,  and  been  issued  shares  of  Common  Stock  in  accordance  with the
provisions hereof.

         17.  Governing  Law. The  provisions and terms of this Warrant shall be
governed  by  and  construed  in  accordance  with  the  internal  laws  of  the
Commonwealth of Massachusetts.

         18.  Business  Days. If the last or appointed day for the taking of any
action  required  or the  expiration  of any  right  granted  herein  shall be a
Saturday or Sunday or a legal holiday in Massachusetts,  then such action may be
taken or  right  may be  exercised  on the next  succeeding  day  which is not a
Saturday or Sunday or such a legal holiday.

                                 1991 STOCK PLAN



         1.  PURPOSE.  This 1991 Stock Plan (the  "Plan") is intended to provide
incentives: (a) to the officers and other employees of DynaGen, Inc., a Delaware
corporation  (the  "Company"),  its  parent  (if any) and any  present or future
subsidiaries of the Company (collectively,  "Related Corporations") by providing
them with  opportunities  to purchase  stock in the Company  pursuant to options
granted  hereunder  which qualify as  "incentive  stock  options"  under Section
422(b) of the Internal  Revenue Code of 1986, as amended (the "Code")  ("ISO" or
"ISOs");  (b) to directors,  officers,  employees and consultants of the Company
and Related  Corporations by providing them with opportunities to purchase stock
in the Company  pursuant to options  granted  hereunder  which do not qualify as
ISOs  ("Non-Qualified  Option" or  "Non-Qualified  Options");  (c) to directors,
officers,  employees and consultants of the Company and Related  Corporations by
providing  them  with  awards  of stock in the  Company  ("Awards");  and (d) to
directors,  officers,  employees  and  consultants  of the  Company  and Related
Corporations by providing them with  opportunities  to make direct  purchases of
stock in the  Company  ("Purchases").  Both ISOs and  Non-Qualified  Options are
referred to hereafter individually as an "Option" and collectively as "Options."
Options,  Awards and  authorizations to make Purchases are referred to hereafter
collectively  as  "Stock  Rights."  As  used  herein,  the  terms  "parent"  and
"subsidiary"   mean   "parent   corporation"   and   "subsidiary   corporation,"
respectively, as those terms are defined in Section 424 of the Code.

      2. ADMINISTRATION OF THE PLAN.

         A. BOARD OR COMMITTEE ADMINISTRATION. The Plan shall be administered by
      the Board of  Directors  of the  Company  (the  "Board") or by a committee
      appointed by the Board (the  "Committee");  provided,  that, to the extent
      required by Rule 16b-3, or any successor  provision ("Rule 16b-3"), of the
      Securities  Exchange Act of 1934, with respect to specific grants of Stock
      Rights, the Plan shall be administered by a disinterested administrator or
      administrators  within  the  meaning  of  Rule  16b-3.  Hereinafter,   all
      references  in this  Plan to the  "Committee"  shall  mean the Board if no
      Committee  has been  appointed.  Subject to  ratification  of the grant or
      authorization  of  each  Stock  Right  by the  Board  (if so  required  by
      applicable state law), and subject to the terms of the Plan, the Committee
      shall have the authority to (i) determine the employees of the Company and
      Related  Corporations  (from among the class of employees  eligible  under
      paragraph 3 to receive ISOs) to whom ISOs may be granted, and to determine
      (from among the class of individuals and entities eligible under paragraph
      3 to receive  Non-Qualified  Options and Awards and to make  Purchases) to
      whom  Non-Qualified  Options,  Awards and authorizations to make Purchases
      may be  granted;  (ii)  determine  the time or times at which  Options  or
      Awards may be granted or Purchases made;  (iii) determine the option price
      of shares  subject to each Option,  which price shall not be less than the
      minimum price  specified in paragraph 6, and the purchase 





                                       2

      price of shares  subject to each  Purchase;  (iv)  determine  whether each
      Option granted shall be an ISO or a  Non-Qualified  Option;  (v) determine
      (subject to  paragraph  7) the time or times when each Option shall become
      exercisable  and the  duration  of the  exercise  period;  (vi)  determine
      whether  restrictions  such as  repurchase  options  are to be  imposed on
      shares  subject to Options,  Awards and  Purchases  and the nature of such
      restrictions,  if any,  and (vii)  interpret  the Plan and  prescribe  and
      rescind rules and regulations  relating to it. If the Committee determines
      to issue a Non-Qualified  Option,  it shall take whatever actions it deems
      necessary,  under Section 422 of the Code and the regulations  promulgated
      thereunder,  to ensure  that such  Option is not  treated  as an ISO.  The
      interpretation  and construction by the Committee of any provisions of the
      Plan or of any  Stock  Right  granted  under  it  shall  be  final  unless
      otherwise  determined  by the Board.  The  Committee may from time to time
      adopt such rules and  regulations for carrying out the Plan as it may deem
      best.  No  member of the Board or the  Committee  shall be liable  for any
      action or determination made in good faith with respect to the Plan or any
      Stock Right granted under it.

         B.  COMMITTEE  ACTIONS.  The Committee may select one of its members as
      its  chairman,  and shall hold  meetings at such time and places as it may
      determine.  Acts by a majority  of the  Committee,  or acts  reduced to or
      approved  in writing by a majority  of the  members of the  Committee  (if
      consistent  with  applicable  state  law),  shall be the valid acts of the
      Committee.  From  time to time  the  Board  may  increase  the size of the
      Committee and appoint additional members thereof,  remove members (with or
      without  cause) and  appoint new members in  substitution  therefor,  fill
      vacancies  however  caused,  or remove all  members of the  Committee  and
      thereafter directly administer the Plan.

         C. GRANT OF STOCK RIGHTS TO BOARD MEMBERS.  Stock Rights may be granted
      to  members  of the  Board  consistent  with the  provisions  of the first
      sentence of  paragraph  2(A)  above,  if  applicable.  All grants of Stock
      Rights to  members  of the Board  shall in all other  respects  be made in
      accordance  with the provisions of this Plan  applicable to other eligible
      persons. Members of the Board who are either (i) eligible for Stock Rights
      pursuant to the Plan or (ii) have been  granted  Stock  Rights may vote on
      any matters  affecting the  administration of the Plan or the grant of any
      Stock  Rights  pursuant to the Plan,  except that no such member shall act
      upon the granting to himself of Stock  Rights,  but any such member may be
      counted in  determining  the  existence  of a quorum at any meeting of the
      Board  during which action is taken with respect to the granting to him of
      Stock Rights.

         3. ELIGIBLE  EMPLOYEES AND OTHERS.  ISOs may be granted to any employee
of the Company or any Related  Corporation.  Those officers and directors of the
Company  who  are  not  employees  may  not be  granted  ISOs  under  the  Plan.
Non-Qualified  Options,  Awards  and  authorizations  to make  Purchases  may be
granted to any employee,  officer or director  (whether or not also an employee)
or consultant of the Company or any Related Corporation.  The Committee may take
into consideration a recipient's individual circumstances in determining whether
to grant an ISO, a Non-Qualified  Option, an Award or an authorization to make a
Purchase.  Granting of any Stock Right to any individual or entity shall neither
entitle that individual or entity to, nor disqualify him from,  participation in
any other grant of Stock Rights.






                                       3

         4. STOCK.  The stock subject to Options,  Awards and Purchases shall be
authorized  but unissued  shares of Common Stock of the Company,  par value $.01
per share (the  "Common  Stock"),  or shares of Common Stock  reacquired  by the
Company  in any  manner.  The  aggregate  number of  shares  which may be issued
pursuant  to the  Plan is  2,600,000,  subject  to  adjustment  as  provided  in
paragraph  13. Any such shares may be issued as ISOs,  Non-Qualified  Options or
Awards,  or to persons or entities  making  Purchases,  so long as the number of
shares so issued does not exceed such number, as adjusted. If any Option granted
under the Plan shall  expire or  terminate  for any reason  without  having been
exercised in full or shall cease for any reason to be exercisable in whole or in
part,  the  unpurchased  shares subject to such Options shall again be available
for grants of Stock Rights under the Plan.

         No person may be granted  Options to acquire,  in the  aggregate,  more
than  750,000  of shares of Common  Stock  under the Plan  during any one fiscal
year.  If any Option  granted  under the Plan shall expire or terminate  for any
reason without having been exercised in full or shall cease for any reason to be
exercisable  in whole or in part or shall be  repurchased  by the  Company,  the
shares  subject to such Option  shall be included  in the  determination  of the
aggregate  number of shares of Common  Stock deemed to have been granted to such
person under the Plan.

         5. GRANTING OF STOCK RIGHTS. Stock Rights may be granted under the Plan
at any time after  October 14, 1991 and prior to October 14,  2001.  The date of
grant  of a Stock  Right  under  the  Plan  will be the  date  specified  by the
Committee at the time it grants the Stock Right;  provided,  however,  that such
date shall not be prior to the date on which the  Committee  acts to approve the
grant. The Committee shall have the right, with the consent of the optionee,  to
convert an ISO  granted  under the Plan to a  Non-Qualified  Option  pursuant to
paragraph 16.

         6.       MINIMUM OPTION PRICE; ISO LIMITATIONS.

         A.  PRICE  FOR  NON-QUALIFIED  OPTIONS.  The  exercise  price per share
      specified in the agreement relating to each  Non-Qualified  Option granted
      under  the  Plan  shall  in no  event  be  less  than  the  minimum  legal
      consideration required therefor under the laws of the State of Delaware or
      the laws of any  jurisdiction  in which the Company or its  successors  in
      interest may be organized.

         B.  PRICE FOR ISOS.  The  exercise  price  per share  specified  in the
      agreement  relating to each ISO  granted  under the Plan shall not be less
      than the fair market  value per share of Common  Stock on the date of such
      grant.  In the case of an ISO to be granted to an  employee  owning  stock
      possessing  more than ten percent (10%) of the total combined voting power
      of all  classes of stock of the Company or any  Related  Corporation,  the
      price per share specified in the agreement  relating to such ISO shall not
      be less than one hundred ten percent  (110%) of the fair market  value per
      share of Common Stock on the date of grant.

         C. $100,000 ANNUAL  LIMITATION ON ISOS.  Each eligible  employee may be
      granted ISOs only to the extent that, in the aggregate under this Plan and
      all  incentive   stock  option  plans  of  the  Company  and  any  Related
      Corporation,  the value of Common Stock 






                                       4

      (determined  at the time ISOs were granted)  which is subject to ISOs that
      become exercisable for the first time by such employee during any calendar
      year does not exceed  $100,000.  Any  options  granted to an  employee  in
      excess of such amount will be granted as Non-Qualified Options.

         D.  DETERMINATION  OF FAIR MARKET  VALUE.  If, at the time an Option is
      granted  under the Plan,  the Company's  Common Stock is publicly  traded,
      "fair market  value" shall be  determined  as of the last business day for
      which the prices or quotes  discussed in this sentence are available prior
      to the date such Option is granted and shall mean (i) the average (on that
      date) of the high and low  prices  of the  Common  Stock on the  principal
      national  securities  exchange on which the Common Stock is traded, if the
      Common Stock is then traded on a national securities exchange; or (ii) the
      last  reported sale price (on that date) of the Common Stock on the NASDAQ
      National Market List, if the Common Stock is not then traded on a national
      securities  exchange;  or (iii) the  closing  bid price (or average of bid
      prices) last quoted (on that date) by an established quotation service for
      over-the-counter  securities,  if the Common  Stock is not reported on the
      NASDAQ National Market List.  However, if the Common Stock is not publicly
      traded at the time an  Option is  granted  under  the Plan,  "fair  market
      value"  shall be  deemed  to be the  fair  value  of the  Common  Stock as
      determined by the Committee  after taking into  consideration  all factors
      which it deems appropriate, including, without limitation, recent sale and
      offer prices of the Common  Stock in private  transactions  negotiated  at
      arm's length.

         7.  OPTION  DURATION.  Subject to earlier  termination  as  provided in
paragraphs  9 and 10,  each Option  shall  expire on the date  specified  by the
Committee, but not more than (i) ten years and one day from the date of grant in
the case of Non-Qualified  Options, (ii) ten years from the date of grant in the
case of ISOs generally,  and (iii) five years from the date of grant in the case
of ISOs  granted to an employee  owning stock  possessing  more than ten percent
(10%) of the total combined  voting power of all classes of stock of the Company
or any  Related  Corporation.  Subject to earlier  termination  as  provided  in
paragraphs  9 and 10,  the term of each ISO  shall be the term set  forth in the
original  instrument  granting such ISO, except with respect to any part of such
ISO that is converted into a Non-Qualified Option pursuant to paragraph 16.

         8.  EXERCISE  OF OPTION.  Subject to the  provisions  of  paragraphs  9
through 12, each Option granted under the Plan shall be exercisable as follows:

         A. VESTING. The Option shall either be fully exercisable on the date of
      grant or shall become  exercisable  thereafter in such installments as the
      Committee may specify.

         B.  FULL  VESTING  OF   INSTALLMENTS.   Once  an  installment   becomes
      exercisable it shall remain exercisable until expiration or termination of
      the Option, unless otherwise specified by the Committee.

         C. PARTIAL EXERCISE. Each Option or installment may be exercised at any
      time or from time to time, in whole or in part, for up to the total number
      of shares with respect to which it is then exercisable.






                                       5


         D.  ACCELERATION  OF  VESTING.  The  Committee  shall have the right to
      accelerate the date of exercise of any installment of any Option; provided
      that  the  Committee  shall  not,  without  the  consent  of an  optionee,
      accelerate  the exercise date of any  installment of any Option granted to
      any employee as an ISO (and not previously  converted into a Non-Qualified
      Option  pursuant to paragraph 16) if such  acceleration  would violate the
      annual  vesting  limitation  contained in Section  422(d) of the Code,  as
      described in paragraph 6(C).

         E. EXTENSION OF EXERCISE PERIOD.  Notwithstanding  any provision herein
      to the contrary, the Committee may, in its discretion, extend the exercise
      period with respect to any Non-Qualified Option.

         9. TERMINATION OF EMPLOYMENT.  If an ISO optionee ceases to be employed
by the  Company and all  Related  Corporations  other than by reason of death or
disability as defined in paragraph 10, no further installments of his ISOs shall
become  exercisable,  and his ISOs shall  terminate  after the passage of ninety
(90) days from the date of termination of his employment,  but in no event later
than on their specified  expiration  dates,  except to the extent that such ISOs
(or  unexercised  installments  thereof) have been converted into  Non-Qualified
Options  pursuant to paragraph 16.  Employment shall be considered as continuing
uninterrupted  during any bona fide leave of absence (such as those attributable
to illness,  military  obligations or  governmental  service)  provided that the
period of such leave does not  exceed 90 days or, if longer,  any period  during
which such optionee's  right to  reemployment  is guaranteed by statute.  A bona
fide leave of absence with the written  approval of the  Committee  shall not be
considered  an  interruption  of employment  under the Plan,  provided that such
written approval contractually  obligates the Company or any Related Corporation
to continue the employment of the optionee after the approved period of absence.
ISOs  granted  under the Plan shall not be affected by any change of  employment
within or among the Company and Related  Corporations,  so long as the  optionee
continues to be an employee of the Company or any Related  Corporation.  Nothing
in the Plan shall be deemed to give any  grantee of any Stock Right the right to
be  retained  in  employment  or other  service by the  Company  or any  Related
Corporation for any period of time.

         10.  DEATH; DISABILITY.

         A. DEATH.  If an ISO optionee  ceases to be employed by the Company and
      all  Related  Corporations  by reason of his death,  any ISO of his may be
      exercised,  to the extent of the number of shares with respect to which he
      could have exercised it on the date of his death, by his estate,  personal
      representative  or beneficiary  who has acquired the ISO by will or by the
      laws of descent and distribution,  at any time prior to the earlier of the
      specified  expiration  date of the ISO or 180  days  from  the date of the
      optionee's death.

         B. DISABILITY.  If an ISO optionee ceases to be employed by the Company
      and all Related  Corporations by reason of his  disability,  he shall have
      the right to exercise  any ISO held by him on the date of  termination  of
      employment, to the extent of the number of shares with respect to which he
      could have  exercised it on that date, at any time prior to the earlier of
      the specified  expiration date of the ISO or 180 days from the date of the
      termination  of






                                        6


      the  optionee's  employment.  For  the  purposes  of the  Plan,  the  term
      "disability"  shall mean  "permanent  and total  disability" as defined in
      Section 22(e)(3) of the Code or successor statute.

         11. ASSIGNABILITY. No Option shall be assignable or transferable by the
optionee  except by will or by the laws of descent  and  distribution  or,  with
respect  to  Non-qualified  Options  only,  pursuant  to  a  qualified  domestic
relations  order as  defined in the Code or Title I of the  Employee  Retirement
Income  Security  Act,  or the rules  thereunder.  During  the  lifetime  of the
optionee each ISO shall be exercisable only by him.

         12.  TERMS AND  CONDITIONS  OF OPTIONS.  Options  shall be evidenced by
instruments  (which need not be  identical)  in such forms as the  Committee may
from time to time  approve.  Such  instruments  shall  conform  to the terms and
conditions  set forth in  paragraphs  6 through 11 hereof and may  contain  such
other  provisions as the Committee deems  advisable  which are not  inconsistent
with the Plan,  including  restrictions  applicable  to  shares of Common  Stock
issuable upon exercise of Options.  In granting any  Non-Qualified  Option,  the
Committee  may specify  that such  Non-Qualified  Option shall be subject to the
restrictions set forth herein with respect to ISOs, or to such other termination
and  cancellation  provisions as the Committee may determine.  The Committee may
from time to time confer authority and  responsibility on one or more of its own
members  and/or one or more  officers of the Company to execute and deliver such
instruments.  The proper  officers of the Company are authorized and directed to
take any and all action  necessary or  advisable  from time to time to carry out
the terms of such instruments.

         13. ADJUSTMENTS. Upon the occurrence of any of the following events, an
optionee's  rights with  respect to Options  granted to him  hereunder  shall be
adjusted as hereinafter provided,  unless otherwise specifically provided in the
written agreement between the optionee and the Company relating to such Option:

         A. STOCK  DIVIDENDS  AND STOCK  SPLITS.  If the shares of Common  Stock
      shall be subdivided or combined into a greater or smaller number of shares
      or if the  Company  shall  issue any  shares  of  Common  Stock as a stock
      dividend on its outstanding  Common Stock,  the number of shares of Common
      Stock  deliverable  upon the  exercise of Options  shall be  appropriately
      increased or decreased proportionately,  and appropriate adjustments shall
      be made in the  purchase  price per  share to  reflect  such  subdivision,
      combination or stock dividend.

         B. CONSOLIDATIONS OR MERGERS. If the Company is to be consolidated with
      or acquired by another  entity in a merger,  sale of all or  substantially
      all of the Company's assets or otherwise (an "Acquisition"), the Committee
      or the board of directors of any entity  assuming the  obligations  of the
      Company  hereunder  (the  "Successor  Board"),  shall,  as to  outstanding
      Options,  either (i) make  appropriate  provision for the  continuation of
      such Options by  substituting  on an  equitable  basis for the shares then
      subject to such  Options the  consideration  payable  with  respect to the
      outstanding shares of Common Stock in connection with the Acquisition;  or
      (ii) make  appropriate  provision for the  continuation of such Options by
      substituting  on an  equitable  basis for the shares then  subject to such





                                       7


      Options any equity securities of the successor corporation;  or (iii) upon
      written  notice  to the  optionees,  provide  that  all  Options  must  be
      exercised,  to the extent then  exercisable,  within a specified number of
      days of the date of such  notice,  at the end of which  period the Options
      shall  terminate;  or (iv)  terminate  all Options in exchange  for a cash
      payment equal to the excess of the fair market value of the shares subject
      to such Options (to the extent then  exercisable)  over the exercise price
      thereof;  or (v) accelerate the date of exercise of such Options or of any
      installment of such Options; or (vi) terminate all Options in exchange for
      the right to  participate  in any stock option or other  employee  benefit
      plan of any successor corporation.

         C.   RECAPITALIZATION   OR   REORGANIZATION.   In   the   event   of  a
      recapitalization   or   reorganization   of  the  Company  (other  than  a
      transaction   described  in   subparagraph  B  above)  pursuant  to  which
      securities  of the  Company or of  another  corporation  are  issued  with
      respect  to the  outstanding  shares of Common  Stock,  an  optionee  upon
      exercising  an Option shall be entitled to receive for the purchase  price
      paid upon such  exercise the  securities  he would have received if he had
      exercised his Option prior to such recapitalization or reorganization.

         D. MODIFICATION OF ISOS. Notwithstanding the foregoing, any adjustments
      made  pursuant to  subparagraphs  A, B or C with  respect to ISOs shall be
      made only after the  Committee,  after  consulting  with  counsel  for the
      Company,   determines   whether  such   adjustments   would  constitute  a
      "modification" of such ISOs (as that term is defined in Section 424 of the
      Code) or would cause any adverse tax  consequences for the holders of such
      ISOs. If the Committee  determines that such adjustments made with respect
      to ISOs would  constitute a modification of such ISOs, it may refrain from
      making such adjustments.

         E. DISSOLUTION OR LIQUIDATION. In the event of the proposed dissolution
      or  liquidation  of the Company,  each Option will  terminate  immediately
      prior to the  consummation  of such proposed  action or at such other time
      and  subject  to such  other  conditions  as  shall be  determined  by the
      Committee.

         F. ISSUANCES OF SECURITIES.  Except as expressly  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  subject  to  Options.  No  adjustments  shall be made for
      dividends  paid  in cash  or in  property  other  than  securities  of the
      Company.

         G. FRACTIONAL  SHARES.  No fractional  shares shall be issued under the
      Plan and the optionee  shall receive from the Company cash in lieu of such
      fractional shares.

         H.  ADJUSTMENTS.  Upon the happening of any of the events  described in
      subparagraphs  A, B or C above,  the class and aggregate  number of shares
      set forth in  paragraph 4 hereof that are  subject to Stock  Rights  which
      previously have been or  subsequently  may be granted under the Plan shall
      also be  appropriately  adjusted to reflect the events  described  in such
      subparagraphs.  The Committee or the Successor  Board shall 






                                       8


      determine the specific adjustments to be made under this paragraph 13 and,
      subject to paragraph 2, its determination shall be conclusive.

         If any person or entity  owning  restricted  Common  Stock  obtained by
exercise of a Stock Right made hereunder  receives  shares or securities or cash
in connection with a corporate  transaction described in subparagraphs A, B or C
above as a result  of  owning  such  restricted  Common  Stock,  such  shares or
securities or cash shall be subject to all of the  conditions  and  restrictions
applicable to the  restricted  Common Stock with respect to which such shares or
securities or cash were issued,  unless otherwise determined by the Committee or
the Successor Board.

         14. MEANS OF  EXERCISING  STOCK  RIGHTS.  A Stock Right (or any part or
installment  thereof) shall be exercised by giving written notice to the Company
at its  principal  office  address.  Such notice shall  identify the Stock Right
being exercised and specify the number of shares as to which such Stock Right is
being  exercised,  accompanied  by full payment of the purchase  price  therefor
either  (a)  in  United  States  dollars  in  cash  or by  check,  or (b) at the
discretion of the Committee, through delivery of shares of Common Stock having a
fair  market  value equal as of the date of the  exercise  to the cash  exercise
price of the Stock Right,  (c) at the discretion of the Committee and consistent
with applicable  law,  through the delivery of an assignment to the Company of a
sufficient  amount of the proceeds  from the sale of the Common  Stock  acquired
upon exercise of the Stock Right and an  authorization  to the broker or selling
agent  to  pay  that  amount  to  the  Company,  which  sale  shall  be  at  the
participant's direction at the time of exercise, or (d) at the discretion of the
Committee,  by any  combination  of (a),  (b) and (c)  above.  If the  Committee
exercises its  discretion to permit  payment of the exercise  price of an ISO by
means of the  methods  set forth in  clauses  (b),  (c) or (d) of the  preceding
sentence, such discretion shall be exercised in writing at the time of the grant
of the ISO in question. The holder of a Stock Right shall not have the rights of
a  shareholder  with respect to the shares  covered by his Stock Right until the
date of  issuance  of a stock  certificate  to him for such  shares.  Except  as
expressly   provided   above  in   paragraph  13  with  respect  to  changes  in
capitalization and stock dividends, no adjustment shall be made for dividends or
similar  rights  for  which  the  record  date is  before  the date  such  stock
certificate is issued.

         15. TERM AND  AMENDMENT OF PLAN.  This Plan was adopted by the Board on
October 14, 1991,  subject (with respect to the validation of ISOs granted under
the Plan) to approval of the Plan by the stockholders of the Company at the next
Meeting of Stockholders or, in lieu thereof, by written consent. If the approval
of  stockholders  is not obtained  prior to October 14, 1992, any grants of ISOs
under the Plan made prior to that date will be rescinded.  The Plan shall expire
at the end of the day on October 14, 2001 (except as to Options  outstanding  on
that date).  Subject to the provisions of paragraph 5 above, Stock Rights may be
granted  under the Plan prior to the date of  stockholder  approval of the Plan.
The Board may  terminate  or amend the Plan in any  respect at any time,  except
that, without the approval of the stockholders  obtained within 12 months before
or after the Board adopts a resolution authorizing any of the following actions:
(a) the  total  number of  shares  that may be issued  under the Plan may not be
materially  increased  (except by adjustment  pursuant to paragraph 13); (b) the
provisions  of paragraph 3 regarding  eligibility  for grants of ISOs may not be
modified;  (c) the  provisions of paragraph 6(B) regarding 







                                       9


the exercise  price at which  shares may be offered  pursuant to ISOs may not be
modified (except by adjustment pursuant to paragraph 13); and (d) the expiration
date of the Plan may not be  extended.  Except  as  otherwise  provided  in this
paragraph  15, in no event may  action  of the  Board or  stockholders  alter or
impair the rights of a  grantee,  without  his  consent,  under any Stock  Right
previously granted to him.

         16. CONVERSION OF ISOS INTO NON-QUALIFIED OPTIONS; TERMINATION OF ISOS.
The  Committee,  at the written  request of any optionee,  may in its discretion
take such actions as may be necessary  to convert such  optionee's  ISOs (or any
installments or portions of  installments  thereof) that have not been exercised
on the date of conversion  into  Non-Qualified  Options at any time prior to the
expiration  of such ISOs,  regardless  of whether the optionee is an employee of
the  Company  or a  Related  Corporation  at the time of such  conversion.  Such
actions may include,  but not be limited to,  extending  the exercise  period or
reducing the exercise price of the appropriate installments of such ISOs. At the
time of such  conversion,  the Committee  (with the consent of the optionee) may
impose such conditions on the exercise of the resulting Non-Qualified Options as
the Committee in its  discretion may  determine,  provided that such  conditions
shall not be inconsistent with this Plan. Nothing in the Plan shall be deemed to
give any  optionee  the  right  to have  such  optionee's  ISOs  converted  into
Non-Qualified  Options,  and no such conversion shall occur until and unless the
Committee  takes  appropriate  action.  The  Committee,  with the consent of the
optionee,  may also terminate any portion of any ISO that has not been exercised
at the time of such termination.

         17. APPLICATION OF FUNDS. The proceeds received by the Company from the
sale of shares  pursuant to Options granted and Purchases  authorized  under the
Plan shall be used for general corporate purposes.

         18.  GOVERNMENTAL  REGULATION.  The  Company's  obligation  to sell and
deliver shares of the Common Stock under this Plan is subject to the approval of
any  governmental  authority  required  in  connection  with the  authorization,
issuance or sale of such shares.

         19.  WITHHOLDING  OF ADDITIONAL  INCOME  TAXES.  Upon the exercise of a
Non-Qualified  Option, the grant of an Award, the making of a Purchase of Common
Stock  for less  than its fair  market  value,  the  making  of a  Disqualifying
Disposition  (as defined in paragraph  20) or the vesting of  restricted  Common
Stock  acquired on the  exercise of a Stock Right  hereunder,  the  Company,  in
accordance  with Section  3402(a) of the Code,  may require the optionee,  Award
recipient  or purchaser to pay  additional  withholding  taxes in respect of the
amount that is considered compensation includible in such person's gross income.
The  Committee in its  discretion  may  condition (i) the exercise of an Option,
(ii) the grant of an Award,  (iii) the making of a Purchase of Common  Stock for
less than its fair market value, or (iv) the vesting of restricted  Common Stock
acquired  by  exercising  a  Stock  Right,  on the  grantee's  payment  of  such
additional withholding taxes.

         20. NOTICE TO COMPANY OF DISQUALIFYING  DISPOSITION.  Each employee who
receives  an ISO must agree to notify the Company in writing  immediately  after
the employee  makes a  Disqualifying  Disposition  of any Common Stock  acquired
pursuant  to  the  exercise  of an  ISO.  A 








                                       10


Disqualifying Disposition is any disposition (including any sale) of such Common
Stock  before the later of (a) two years after the date the employee was granted
the ISO, or (b) one year after the date the  employee  acquired  Common Stock by
exercising  the ISO. If the employee  has died before such stock is sold,  these
holding period  requirements do not apply and no  Disqualifying  Disposition can
occur thereafter.

         21. GOVERNING LAW;  CONSTRUCTION.  The validity and construction of the
Plan and the instruments  evidencing  Stock Rights shall be governed by the laws
of the State of Delaware,  or the laws of any  jurisdiction in which the Company
or its  successors in interest may be organized.  In construing  this Plan,  the
singular  shall  include the plural and the  masculine  gender shall include the
feminine and neuter, unless the context otherwise requires.

                                                          No   person   may   be
                                                 granted Options to acquire,  in
                                                 the   aggregate,    more   than
                                                 750,000  of  shares  of  Common
                                                 Stock under the Plan during any
                                                 one fiscal year.  If any Option
                                                 granted  under  the Plan  shall
                                                 expire  or  terminate  for  any
                                                 reason   without   having  been
                                                 exercised   in  full  or  shall
                                                 cease  for  any  reason  to  be
                                                 exercisable in whole or in part
                                                 or shall be  repurchased by the

                                  DYNAGEN, INC.

                      Non-Qualified Stock Option Agreement


         DYNAGEN,  INC., a Delaware  corporation (the "Company"),  hereby grants
this 28th day of October, 1996, to Michael Sorell (the "Optionee"), an option to
purchase a maximum of 330,000 shares (the "Option Shares") of Common Stock, $.01
par  value  (the  "Common  Stock"),  at the  price of $1.31  per  share,  on the
following terms and conditions:

         1.  GRANT AS  NON-QUALIFIED  OPTION;  OTHER  OPTIONS.  This  Option  is
intended to be a  Non-Qualified  Option (rather than an incentive stock option),
and the Board of Directors or any committee appointed by the Board to administer
the Company's options  (hereinafter,  all references to the "Committee" mean the
committee  so appointed or the Board if no such  committee  has been  appointed)
intends to take appropriate  action, if necessary,  to achieve this result. This
Option is in addition to any other options  heretofore  or hereafter  granted to
the Optionee by the Company,  but a duplicate  original of this instrument shall
not affect the grant of another option.

         2. EXTENT OF OPTION IF BUSINESS RELATIONSHIP CONTINUES. If the Optionee
has  continued  to serve the Company in the  capacity of an  employee,  officer,
director,  agent,  advisor,  or consultant  (such service is described herein as
maintaining or being involved in a "Business Relationship" with the Company), on
the  following  dates,  the Optionee may exercise  this Option for the number of
Option Shares set opposite the applicable date:

    Less than one year from the date hereof      -     No shares

    One year but less than two years from        -     25% of the Option Shares
    the date hereof

    Two years but less than three years from     -     An additional 35% of the
    the date hereof                                    Option Shares

    Three years from the date hereof             -     An additional 40% of the
                                                       Option Shares

The  foregoing  rights are  cumulative  and,  while the  Optionee  continues  to
maintain a Business  Relationship  with the Company,  may be exercised up to and
including  the date  which is seven  (7)  years  from the date  this  Option  is
granted.  All of the  foregoing  rights  are  subject  to  Sections  3 and 4, as
appropriate, if the Optionee ceases to maintain a Business Relationship with the
Company or dies,  becomes disabled or undergoes  dissolution while involved in a
Business Relationship with the Company.

         3.  TERMINATION  OF BUSINESS  RELATIONSHIP.  If the Optionee  ceases to
maintain a Business Relationship with the Company, other than by reason of death
or  disability as defined 







in Section 4, no further  installments  of this Option shall become  exercisable
and this Option shall  terminate  after the passage of thirty (30) days from the
date the Business  Relationship ceases, but in no event later than the scheduled
expiration  date. In such a case, the Optionee's only rights  hereunder shall be
those which are properly exercised before the termination of this Option.

         4. DEATH; DISABILITY. If the Optionee dies while involved in a Business
Relationship  with the Company,  this Option may be exercised,  to the extent of
the  number of Option  Shares  with  respect  to which the  Optionee  could have
exercised it on the date of his death, by his estate, personal representative or
beneficiary to whom this Option has been assigned  pursuant to Section 9, at any
time within 180 days after the date of death,  but not later than the  scheduled
expiration  date. If the Optionee's  Business  Relationship  with the Company is
terminated by reason of disability,  this Option may be exercised, to the extent
of the number of Option  Shares with  respect to which the  Optionee  could have
exercised it on the date the Business  Relationship was terminated,  at any time
within  180 days  after the date of such  termination,  but not  later  than the
scheduled  expiration  date.  At the  expiration  of such 180-day  period or the
scheduled expiration date, whichever is the earlier, this Option shall terminate
and the only rights hereunder shall be those as to which the Option was properly
exercised   before  such   termination.   If  the  Optionee  is  a  corporation,
partnership,  trust or  other  entity  that is  dissolved,  liquidated,  becomes
insolvent  or enters  into a merger or  acquisition  with  respect to which such
Optionee is not the surviving entity at the time when such entity is involved in
a  Business  Relationship  with  the  Company,  this  Option  shall  immediately
terminate as of the date of such event,  and the only rights  hereunder shall be
those as to which this Option shall immediately terminate as of the date of such
event,  and the only rights hereunder shall be those as to which this Option was
properly exercised before such dissolution or other event.

         5.  PARTIAL  EXERCISE.  Exercise of this Option up to the extent  above
stated  may be made in part at any time and from time to time  within  the above
limits,  except that this Option may not be exercised  for a fraction of a share
unless such exercise is with respect to the final  installment  of stock subject
to this Option and a fractional  share (or cash in lieu  thereof) must be issued
to permit the  Optionee  to  exercise  completely  such final  installment.  Any
fractional  share with respect to which an  installment of this Option cannot be
exercised  because of the limitation  contained in the preceding  sentence shall
remain  subject to this Option and shall be available for later  purchase by the
Optionee in accordance with the terms hereof.

         6.  PAYMENT OF PRICE.  The option  exercise  price is payable in United
States dollars and may be paid:

                  (a) in cash or by check,  or any combination of the foregoing,
equal in amount to the option exercise price; or

                  (b) in the discretion of the Committee,  in cash, by check, by
delivery of shares of the Company's  Common Stock having a fair market value (as
determined  by the  Committee)  equal as of the date of  exercise  to the option
exercise price,  or by any combination of the foregoing,  equal in amount to the
option exercise price.


                                      -2-




         If the  Optionee  delivers  shares of Common Stock held by the Optionee
(the "Old  Stock")  to the  Company  in full or  partial  payment  of the option
exercise  price,  and the Old Stock so delivered is subject to  restrictions  or
limitations  imposed by agreement  between the  Optionee  and the  Company,  the
Common  Stock  received by the  Optionee on the exercise of this Option shall be
subject to all restrictions  and limitations  applicable to the Old Stock to the
extent that the Optionee paid for such Common Stock by delivery of Old Stock, in
addition to any restrictions or limitations imposed by this Agreement.

         7. AGREEMENT TO PURCHASE FOR INVESTMENT.  By acceptance of this Option,
the Optionee  agrees that a purchase of Option Shares under this Option will not
be  made  with a view  of  their  distribution,  as  that  term  is  used in the
Securities Act of 1993, as amended (the "Securities Act"), unless in the opinion
of counsel to the Company such distribution is in compliance with or exempt from
the  registration  and  prospectus   requirements  of  the  Securities  Act  and
applicable  state securities laws, and the Optionee agrees to sign a certificate
to such  effect  at the time of  exercising  this  Option  and  agrees  that the
certificate  for the Option Shares so purchased shall be inscribed with a legend
to ensure  compliance  with the Securities Act and applicable  state  securities
laws.

         8. METHOD OF EXERCISING OPTION.  Subject to the terms and conditions of
this  Agreement,  this Option may be exercised by written notice to the Company,
at the principal  executive office of the Company,  or to such transfer agent as
the Company  shall  designate.  Such notice shall state the election to exercise
this  Option  and the  number of Option  Shares in  respect of which it is being
exercised  and shall be signed by the person so  exercising  this  Option.  Such
notice shall be accompanied by payment of the full exercise price of such Option
Shares,  and the Company shall deliver a  certificate  representing  such Option
Shares  as  soon  as  practicable  after  the  notice  shall  be  received.  The
certificate  for the Option  Shares as to which this  Option  shall have been so
exercised  shall be  registered  in the name of the  person so  exercising  this
Option  (or,  if this  Option  shall be  exercised  by the  Optionee  and if the
Optionee  shall so  request  in the  notice  exercising  this  Option,  shall be
registered in the name of the Optionee and another person jointly, with right of
survivorship)  and shall be delivered  as provided  above to or upon the written
order of the person  exercising  this Option.  In the event this Option shall be
exercised,  pursuant to Section 4 hereof, by any person other than the Optionee,
such  notice  shall be  accompanied  by  appropriate  proof of the right of such
person to exercise this Option.  All Option Shares that shall be purchased  upon
the  exercise  of this  Option  as  provided  herein  shall  be  fully  paid and
nonassessable.

         9.  OPTION  NOT  TRANSFERABLE.  This  Option  is  not  transferable  or
assignable  except by will, by the laws of descent and  distribution or pursuant
to a qualified  domestic relations order as defined in the Internal Revenue Code
of 1986, as amended,  or Title I of the Employee Retirement Income Security Act,
or the rules thereunder.

         10. NO OBLIGATION TO EXERCISE OPTION.  The grant and acceptance of this
Option imposes no obligation on the Optionee to exercise it.


                                      -3-





         11. NO OBLIGATION TO CONTINUE  BUSINESS  RELATIONSHIP.  The Company and
any  related  corporations  are not by this  Option  obligated  in any manner to
continue to maintain a Business  Relationship  with the Optionee in any capacity
whatsoever.

         12. NO RIGHTS AS STOCKHOLDER UNTIL EXERCISE. The Optionee shall have no
rights as a stockholder  with respect to Option Shares subject to this Agreement
until a stock certificate therefore has been issued to the Optionee and is fully
paid for by the Optionee.

         13.  ADJUSTMENTS.  Upon the occurrence of any of the following  events,
the Optionee's rights with respect to this Option shall be adjusted as follows:

                  A. STOCK  DIVIDENDS AND STOCK SPLITS.  If the shares of Common
         Stock shall be subdivided or combined into a greater or smaller  number
         of shares or if the Company shall issue any shares of Common Stock as a
         stock dividend on its outstanding Common Stock, the Option Shares shall
         be   appropriately   increased   or  decreased   proportionately,   and
         appropriate  adjustments  shall be made in the purchase price per share
         to reflect such subdivision, combination or stock dividend.

                  B.  RECAPITALIZATION  OR  REORGANIZATION.  In the  event  of a
         recapitalization  or  reorganization  of the  Company  (other  than  an
         Acquisition  as defined in Section 16) pursuant to which  securities of
         the Company or of another  corporation  are issued with  respect to the
         outstanding  shares of Common Stock,  the Optionee upon exercising this
         Option  shall be entitled to receive for the  purchase  price paid upon
         such exercise the securities he would have received if he had exercised
         the Option prior to such recapitalization or reorganization.

                  C.  DISSOLUTION OR  LIQUIDATION.  In the event of the proposed
         dissolution or liquidation of the Company,  this Option shall terminate
         immediately  prior to the  consummation  of such proposed  action or at
         such  other  time and  subject  to such  other  conditions  as shall be
         determined by the Committee.

                  D.  ISSUANCES  OF  SECURITIES.  Except as  expressly  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 of price of shares subject to this Option.  No adjustments shall
         be made for dividends paid cash or in property other than securities of
         the Company.

                  E. CAPITAL CHANGES AND BUSINESS  SUCCESSIONS.  In the event of
         any stock dividend, stock split, combination, recapitalization or other
         similar change in the capital structure of the Company, this Option and
         the Option  price shall be equitably  adjusted  and, in lieu of issuing
         fractional  shares  upon  exercise   thereof,   this  Option  (and  the
         corresponding Option Shares) shall be rounded upward or downward to the
         nearest  whole share  (rounding  upward for all amounts  equal to or in
         excess of .51). In particular,  without affecting the generality of the
         foregoing, it is understood that for the purposes of Sections 2 through
         4  hereof,  inclusive,  maintaining  or being  involved  in a  Business


                                      -4-





         Relationship with the Company includes maintaining or being involved in
         a Business  Relationship  with its  parent (if any) and any  present or
         future subsidiaries of the Company.

         14.  WITHHOLDING TAXES. The Optionee hereby agrees that the Company may
withhold from the Optionee's wages or other  remuneration the appropriate amount
of federal, state and local taxes attributable to the Optionee's exercise of any
installment of this Option. At the Company's discretion,  the amount required to
be withheld may be withheld in cash from such wages or other remuneration, or in
kind from the Common Stock otherwise  deliverable to the Optionee on exercise of
this Option.  The Optionee further agrees that, if the Company does not withhold
an amount from the Optionee's wages or other remuneration  sufficient to satisfy
the Company's withholding obligation, the Optionee will reimburse the Company on
demand, in cash, for the amount underwithheld.

         15. NO  EXERCISE  OF OPTION IF  BUSINESS  RELATIONSHIP  TERMINATED  FOR
MISCONDUCT.  If the  Business  Relationship  of the Optionee is  terminated  for
"Misconduct,"  this Option shall  terminate on the date of such  termination and
this  Option  shall  thereupon  not be  exercisable  to any  extent  whatsoever.
"Misconduct" is conduct, as determined by the Board of Directors,  involving one
or more of the following: (i) disloyalty, gross negligence, dishonesty or breach
of  fiduciary  duty  to  the  Company;  or  (ii)  the  commission  of an  act of
embezzlement,  fraud or  deliberate  disregard  of the rules or  policies of the
Company  which  results in loss,  damage or injury to the Company;  or (iii) the
unauthorized  disclosure of any trade secret or confidential  information of the
Company;  or (iv) the commission of an act which constitutes  unfair competition
with the  Company  or which  induces  any  customer  of the  Company  to break a
contract with the Company. In making such determination,  the Board of Directors
shall act fairly and in utmost good faith.

         16.  ACCELERATION AND VESTING OF OPTION FOR BUSINESS  COMBINATIONS.  If
the  Company is to be  consolidated  with or  acquired  by  another  entity in a
merger,  sale of all or  substantially  all of the Company's assets or otherwise
(an  "Acquisition"),  then this Option shall,  if the  Committee so  designates,
become fully vested and  exercisable  by the Optionee  immediately  prior to the
consummation of such Acquisition.

         17.  GOVERNING  LAW;  SUCCESSORS AND ASSIGNS.  This Agreement  shall be
governed by and interpreted in accordance with the internal laws of the State of
Delaware  and  shall  be  binding  upon  the  heirs,  personal  representatives,
executors, administrators, successors and assigns of the parties.

         18.  EXPRESS  CONSIDERATION  FOR  OPTION  GRANT.  This  Option is being
granted  to  the  Optionee  on  the  express   condition  and  for  the  express
consideration  that the Optionee has previously  executed,  or will  immediately
execute  and  deliver  in  connection   with  this  Option  grant,   a  form  of
nondisclosure,  assignment of inventions and/or noncompetition agreement (or any
combination thereof) satisfactory to the Company. If such agreement has not been
executed, or if the Optionee refuses to execute such agreement,  this Option may
be canceled by the Company in its sole and absolute discretion.


                                      -5-





         19. ENTIRE AGREEMENT.  This Agreement embodies the entire agreement and
understanding  between the parties  hereto  with  respect to the subject  matter
hereof.


                                      -6-






         IN WITNESS  WHEREOF,  the  Company  and the  Optionee  have caused this
