                                  THE COMPANY
 
   
     The Company is currently engaged in manufacturing and marketing 14 types of
intravenous infusion solutions ('IV Solutions') in Switzerland and  Lichtenstein
and  marketing in Germany raw materials  used to manufacture medications for the
treatment  of  prostate  enlargement  ('Prostate  Materials')  and  two  generic
oncological  products, mercaptopurine and  calcium leucovorin. Over  the next 24
months, the  Company's  strategy  is to  manufacture,  in  its  state-of-the-art
facilities  in Switzerland, and  market generic oncological  drugs. In addition,
the  Company  is  in  the  process  of  preparing  to  market  certain  licensed
proprietary oncological and biotechnological products.
    
 
   
     The Company markets IV Solutions through its own sales force to health care
providers  and third-party payors and markets Prostate Materials, mercaptopurine
and calcium leucovorin to pharmaceutical companies. The Company does not  intend
to market its other products directly to the public. For the year ended December
31, 1995, on a pro forma basis after giving effect to the Bioren Acquisition (as
defined  below)  as if  the transaction  had  occurred on  January 1,  1995, the
Company's sales of IV Solutions and antibiotics were approximately $6.5 million,
sales of medical products, including Prostate Materials, were approximately $1.4
million, and sales of generic oncological products were approximately  $670,000.
For  the three months ended  March 31, 1996, sales  of these products aggregated
approximately $1.4 million, $319,000 and $210,000, respectively.
    
 
     In 1995, the Company obtained distribution rights to, among other products,
sodium leucovorin and five generic oncological products, including  methotrexate
and calcium leucovorin, from Sapec ('Sapec'), a division of Cerbios Pharma SA, a
privately-held    Swiss   pharmaceutical   company   ('Cerbios   Pharma'),   and
approximately 20 generic oncological products, including mercaptopurine, calcium
leucovorin and  methotrexate, from  AB Cernelle  ('Cernelle'), a  privately-held
Swedish  pharmaceutical  company.  Sodium leucovorin  is  designed  to alleviate
certain side  effects associated  with chemotherapy  more effectively  than  its
currently distributed counterpart, calcium leucovorin.
 
     The  Company has received approval for  the marketing in Switzerland of two
generic oncological products, methotrexate and doxorubicin, and expects to begin
marketing these  products during  the  second half  of  1996. The  Company  also
expects  that  all regulatory  approvals for  the sale  of sodium  leucovorin in
Germany will be obtained during the second  half of 1996 and that the  marketing
of  this  product will  begin  shortly thereafter.  There  can be  no assurance,
however, that  such regulatory  approvals  will be  obtained during  these  time
periods,  or that such approvals will ever be obtained. In addition, the Company
has also  obtained  the rights  to  use,  manufacture and  market,  among  other
products,  a  form of  recombinant urokinase  from Bioferment  ('Bioferment'), a
division of Cerbios Pharma. Recombinant urokinase is a biotechnological  product
used in the treatment of cardiovascular disease.

     The  Company  has entered  into exclusive  arrangements with  the following
non-affiliated  pharmaceutical  companies  to  market  certain  proprietary  and
generic  oncological or  biotechnological products, manufactured  or licensed by
the Company, in  various territories: Medac  GmbH ('Medac') in  Germany and  the
United Kingdom; Boehringer Mannheim Italia Spa ('Boehringer') in Italy; Laevosan
International  AG ('Laevosan') in Switzerland;  Laboratories Vita SA ('Vita') in
Spain; and  Protyde  Pharmaceuticals,  Inc. ('Protyde')  worldwide,  except  for
certain  major  European countries.  Medac,  Boehringer, Laevosan  and  Vita are
established pharmaceutical companies. Protyde is a development stage company.
 
     The Company's business strategy over the next 24 months is to:
 
           manufacture and market approximately seven injectable and lyophilized
           oncological products, including sodium leucovorin;
 
           manufacture and market additional oncological products as the patents
           relating to the products expire;
 
           increase the  number of  pharmaceutical companies  in Europe  through
           which  the  Company's  oncological  products  are  marketed  and  the
           territories in which they are distributed;
 
           market recombinant urokinase; and
 
           expand the  marketing  of IV  Solutions  in Switzerland  through  the
           Company's own sales force.
 
     For  the past 25 years,  John G. Tramontana, the  Company's Chairman of the
Board, President and Chief Executive Officer, a United States citizen, served in
various senior executive positions at a number of privately-held  pharmaceutical
companies  including Adria  Laboratories Inc.  (acquired by  Pharmacia & Upjohn,
Inc.), a company specializing  in the manufacture  of oncological products,  Ben
Venue  Laboratories, Inc., a company specializing in the manufacture of sterile,
injectable pharmaceutical  products,  Sapec,  a  division  specializing  in  the
manufacture  of pharmaceutical products,  and Bioferment, a  division engaged in
the research and development  of biotechnological products. At  the time of  the
negotiation  and execution of the Company's  agreements with Sapec, Cernelle and
Bioferment, Mr. Tramontana  was the chief  operating officer and  a director  of
Cerbios  Pharma, chairman of the board of Cernelle and a director of Chemholding
SA ('Chemholding'), a principal stockholder  of the Company. Chemholding is  the
sole stockholder of Cerbios Pharma and Cerbios Pharma is the sole stockholder of
Cernelle.  In March 1996, Mr. Tramontana resigned from all of his positions with
Chemholding, Cerbios Pharma  and Cernelle. There  can be no  assurance that  the
Company will continue its arrangements with Sapec, Cernelle or Bioferment or any
other   collaborators.   See  'Risk   Factors   --  Reliance   on  Collaborative
Arrangements; Management Affiliations with Collaborators.'
 
   
     The Company was incorporated  in Delaware in September  1995 and has  three
wholly-owned subsidiaries, Bigmar Pharmaceuticals, a Swiss corporation formed in
January  1992,  Bigmar  Therapeutics,  Inc., a  Delaware  corporation  formed in
September 1995 ('Bigmar Therapeutics'), and  Bioren, a Swiss corporation  formed
in  July  1986.  In  June  1995, Bigmar  Pharmaceuticals  purchased  all  of the
outstanding capital stock  of Bioren ('Bioren  Acquisition') and  simultaneously
sold  50% of the outstanding capital stock  of Bioren to certain stockholders of
Bigmar  Pharmaceuticals.  On  April  9,  1996,  in  the  Exchange,  all  of  the
stockholders  of Bigmar Pharmaceuticals exchanged all of their shares of capital
stock in Bigmar Pharmaceuticals for an  aggregate of 2,000,938 shares of  Common
Stock  of the Company and  all of the stockholders  of Bioren, other than Bigmar
Pharmaceuticals, exchanged all of their shares of capital stock in Bioren for an
aggregate of 350,312 shares  of Common Stock of  the Company. See 'The  Company'
and 'Certain Transactions.'

                SUMMARY HISTORICAL AND PRO FORMA FINANCIAL DATA
 
     The  following table sets  forth summary historical  financial data for (i)
Bioren SA (predecessor company) for the  years ended December 31, 1993 and  1994
and  for the six months ended June 30, 1995, and (ii) Bigmar, Inc. for the years
ended December 31, 1993, 1994 and 1995 and for the three months ended March  31,
1995  and 1996 (after giving effect to the reorganization described in Note 1 to
the Company's financial  statements). The summary  historical financial data  of
Bioren  and Bigmar, Inc. has been  derived from the audited financial statements
(and notes  thereto) of  the  respective companies  included elsewhere  in  this
Prospectus.  The summary financial data presented as  of March 31, 1995 and 1996
and for the  three months ended  March 31, 1995  and 1996 are  derived from  the
unaudited  financial statements  of the Company  which appear  elsewhere in this
Prospectus. In the  opinion of management,  the summary financial  data for  the
three  months ended March 31, 1995 and 1996 have been prepared on the same basis
as the audited financial statements and reflect all adjustments, which are of  a
normal  recurring nature, necessary to present fairly the financial data for the
periods presented. The  results of  operations for  any interim  period are  not
necessarily  indicative  of the  Company's results  of  operations for  the full
fiscal year. The summary historical financial data should be read in conjunction
with the financial statements (and notes thereto) of Bioren and Bigmar, Inc. and
'Management's Discussion  and Analysis  of Financial  Condition and  Results  of
Operations' included elsewhere in this Prospectus. The following table also sets
forth  pro forma operating data of the  Company as if the Bioren Acquisition had
occurred as of January 1,  1995. The unaudited pro  forma financial data is  for
informational  purposes only, does  not purport to  represent what the Company's
results of operations would have been  if such transaction had in fact  occurred
as  of  such date  and is  not  necessarily indicative  of the  Company's future
results of operations.

(1) On April 9, 1996,  a reorganization of companies  under common control  took
    place whereby the Company acquired 100% of Bigmar Pharmaceuticals and 50% of
    Bioren.  Accordingly, the  financial statements  of the  Company include the
    results of operations  of Bigmar Pharmaceuticals  for all periods  presented
    and  the results  of operations  of Bioren  from July  1, 1995  (the date of
    acquisition).

                                  RISK FACTORS
 
     An  investment in the Common Stock offered hereby involves a high degree of
risk. Prior  to making  any investment  decision, prospective  investors  should
carefully   consider  the  following  risk   factors  together  with  the  other
information presented in this Prospectus including the financial statements (and
notes thereto).
 
   
     DEVELOPMENT STAGE;  HISTORY  OF LOSSES.  The  Company was  incorporated  in
September  1995 and  was a  development stage  company until  it effectuated the
Exchange  resulting   in  the   Company's  ownership   of  Bioren   and   Bigmar
Pharmaceuticals. In addition, the Company and its subsidiaries have incurred net
losses  in the  past. For  the years  ended December  31, 1993  and 1994, Bioren
incurred net losses, before extraordinary item, of approximately $1,804,000  and
$2,984,000,  respectively, and for the year ended December 31, 1995, the Company
(which includes the results of operations of Bioren from July 1, 1995)  incurred
a  net loss of approximately $97,000. For  at least the current fiscal year, the
Company may incur  additional losses which  may be substantial  as a result  of,
among  other things, its expansion strategy. There  can be no assurance that the
Company's operations will achieve profitability at any time in the future or, if
achieved, that such  profitability will  be sustained.  See 'Selected  Financial
Data'  and  'Management's Discussion  and  Analysis of  Financial  Condition and
Results of Operations.'
    
 
   
     EXPANSION OF OFFERED PRODUCTS;  LIMITED EXPERIENCE. The Company's  business
strategy  relies  primarily  on  its  success  in  manufacturing  and  marketing
oncological products and marketing biotechnological  products, an area in  which
the  Company has limited experience. The success of its business strategy should
be considered  in  light of  the  risks, expenses  and  difficulties  frequently
encountered  in entering  into industries characterized  by intense competition;
completing  product  development;  obtaining  regulatory  approvals  in  certain
European  countries, the United States and  elsewhere for its proposed products;
gaining market acceptance of the Company's proposed products; entering into  new
collaborative  agreements and  maintaining existing  collaborative arrangements.
There can be no assurance that the Company will be able to manufacture or market
its proposed products, maintain or expand its market share or achieve commercial
revenues from its proposed products in  the future. In addition, aspects of  the
Company's   business  strategy  can   only  be  implemented   if  the  Company's
manufacturing facility  in  Barbengo,  Switzerland  ('Bigmar  Facility')  and  a
dedicated  area of the  Company's manufacturing facility  in Couvet, Switzerland
('Bioren Facility')  become  fully  operational  and  all  necessary  regulatory
approvals  are  obtained.  Some of  the  foregoing  factors are  not  within the
Company's control and there can be no assurance that the Company will be able to
implement its business strategy,  that the facility  or area under  construction
will  become operational (including obtaining  regulatory approvals) or that its
business  strategy  will  result  in  profitability.  See  'Use  of   Proceeds,'
'Management's  Discussion  and Analysis  of Financial  Condition and  Results of
Operations,' 'Business -- Proposed Products and -- Facilities' and the Company's
financial statements and notes thereto.
    
 
     RELIANCE  ON  COLLABORATIVE  ARRANGEMENTS;  MANAGEMENT  AFFILIATIONS   WITH
COLLABORATORS.  The Company has obtained the rights to manufacture and/or market
certain  proprietary  and  generic  oncological  and  biotechnological  products
developed by other companies. In 1995, the Company entered into distribution and
supply  agreements  with  (i)  Cernelle  relating  to  approximately  20 generic
oncological  products,   including  mercaptopurine,   calcium  leucovorin,   and
methotrexate  ('Cernelle Agreement'),  and (ii)  Sapec relating  to, among other
products, certain proprietary and generic oncological products, including sodium
leucovorin ('Sapec Agreement'). In addition, in 1995, the Company entered into a
license   and   supply   agreement   with   Bioferment   relating   to   certain
biotechnological   products,   including   recombinant   urokinase  ('Bioferment
Agreement'). Pursuant to the terms of these agreements, the Company is obligated
to, among other things,  pay either substantial one-time  fees or make  payments
that,  in  some instances,  may be  substantial upon  the completion  of certain
regulatory milestones with respect to the products covered by the agreements. In
addition, the  Cernelle  Agreement,  the  Sapec  Agreement  and  the  Bioferment
Agreement   may  be   terminated  by   either  party   under  certain  specified
circumstances. There  can be  no assurance  that the  Company will  fulfill  its
obligations  under  any  of  these  agreements or  that  one  or  more  of these
agreements will  not be  terminated. The  loss or  diminution of  rights or  the
termination  of any of these agreements would  have a material adverse effect on
the Company. See 'Business -- Products and -- Proposed Products.'
 
     At the time of the negotiation and execution of the Cernelle Agreement, the
Sapec Agreement and the Bioferment Agreement, John G. Tramontana, the  Company's
Chairman  of the  Board, President, and  Chief Executive Officer,  was the chief
operating   officer    and   a    director   of    Cerbios   Pharma,    chairman
 
                                       8
 <PAGE>
<PAGE>
of the board of Cernelle and a director of Chemholding. Chemholding, a principal
stockholder  of  the Company,  is  the sole  stockholder  of Cerbios  Pharma and
Cerbios Pharma  is  the  sole  stockholder  of  Cernelle.  In  March  1996,  Mr.
Tramontana  resigned from all of his  positions with Chemholding, Cerbios Pharma
and Cernelle. See ' -- Conflicts of Interest,' 'Use of Proceeds,'  'Management's
Discussion  and  Analysis of  Financial  Condition and  Results  of Operations,'
'Business   --    Products   and    --   Proposed    Products'   and    'Certain
Transactions -- Transactions with Principal Stockholders.'
 
     CONFLICTS OF INTEREST. Chemholding, a principal stockholder of the Company,
is the sole stockholder of Cerbios Pharma. Sapec and Bioferment are divisions of
Cerbios  Pharma and Cerbios Pharma is  the sole stockholder of Cernelle. Certain
officers, directors and stockholders of Chemholding own directly and  indirectly
in  the  aggregate approximately  51% of  the  Company's issued  and outstanding
Common Stock  prior  to the  Offering  and will  own  approximately 34%  of  the
Company's  issued and outstanding Common Stock following the consummation of the
Offering. The  Company is  a  party to  agreements  with Sapec,  Bioferment  and
Cernelle.  Prior to March 1996, Mr. Tramontana was an officer and/or director of
each of the foregoing  companies. The Company believes  that the terms of  these
agreements  are no more  favorable to the  Company or the  other parties thereto
than they would  be to unaffiliated  third parties. There  can be no  assurance,
however,  that  the Company  will continue  to maintain  its rights  under these
agreements or that these agreements will  not be terminated in the future.  John
G.  Tramontana is not a stockholder  of Chemholding, Cerbios Pharma or Cernelle.
See ' --  Reliance on Collaborative  Arrangements; Management Affiliations  with
Collaborators,'  'Business --  Products and   --  Proposed Products,' 'Principal
Stockholders' and 'Certain Transactions.'
 
   
     RELIANCE ON PLM.  For the  year ended  December 31,  1995, on  a pro  forma
basis,  sales of IV Solutions comprised approximately 64% of the Company's total
sales. For  the  three  months  ended March  31,  1996,  these  sales  comprised
approximately  72% of the  Company's total sales. In  March 1995, Bioren entered
into an  agreement with  PLM  Langeskov A/S  ('PLM')  pursuant to  which  Bioren
acquired  the exclusive right  to purchase intravenous  solution containers from
PLM  and  to  package  and  distribute  IV  Solutions  in  these  containers  in
Switzerland  and  Lichtenstein ('PLM  Agreement'). Under  the  terms of  the PLM
Agreement, PLM is entitled to terminate the exclusivity portion of the agreement
if, among other things, Bioren does not purchase a minimum number of intravenous
solution containers  each year.  The PLM  Agreement expires  in the  year  2005,
unless  it  is  earlier  terminated.  In  addition,  the  PLM  Agreement  may be
terminated by either party upon the occurrence of certain specified  conditions,
including  if  the products  or  their production  infringe,  or are  alleged to
infringe, the intellectual property rights of third parties. The termination  of
the  PLM Agreement  would have  a material  adverse effect  on the  Company. See
'Management's Discussion  and Analysis  of Financial  Condition and  Results  of
Operations -- Results of Operations' and 'Business -- Products.'
    
 
     RELIANCE  ON NETWORK OF PHARMACEUTICAL  COMPANIES FOR MARKETING; DEPENDENCE
ON ADDITIONAL  COLLABORATIVE  ARRANGEMENTS.  The  Company  has  granted  certain
companies  such as Medac,  Boehringer, Laevosan, Vita  and Protyde the exclusive
right to market and distribute, in certain territories, selected oncological  or
biotechnological  products  of the  Company and  the right  of first  refusal to
market and distribute certain of the  Company's proposed products. As a  result,
the  Company may not  market products or  proposed products that  are covered by
those agreements independently  and may  not enter into  strategic alliances  or
collaborative  arrangements with others relating to  any products covered by (i)
an exclusivity arrangement  or (ii)  a right of  first refusal  (without in  the
latter  instance  first  offering  such  right  to  the  holders).  Restrictions
regarding exclusivity and rights of first refusal limit the Company's ability to
pursue and negotiate  collaborative arrangements  with other  entities on  terms
which may be more favorable to the Company. In addition, the amount of resources
and  the  time that  any  of these  collaborators  devote towards  marketing the
Company's products or proposed  products are not  within the Company's  control.
There  can be no assurance that any marketing, sales or other efforts undertaken
by the Company or its collaborators  will be successful. Each of the  agreements
terminates  under certain specified circumstances and any termination would have
a material adverse effect on the Company. Consistent with its business strategy,
the Company intends to pursue  additional collaborative arrangements with  third
parties.  There can be no  assurance, however, that the  Company will be able to
find additional collaborators or negotiate additional collaborative arrangements
on  terms  acceptable  to  the  Company,  if  at  all,  that  the  collaborative
arrangements  with the  Company will be  successful or,  that collaborators will
devote sufficient  resources to  the Company's  products, proposed  products  or
technologies.  In addition, there can be  no assurance that future collaborative
arrangements will not
 
                                       9
 <PAGE>
<PAGE>
allow others to enter into arrangements with the Company's collaborators for the
commercialization of  the same  product or  that collaborators  will not  pursue
alternative  products  either  on their  own  or in  collaboration  with others,
including the Company's competitors. See 'Business -- Collaborative Agreements.'
 
   
     DEPENDENCE ON SIGNIFICANT CUSTOMERS. For the years ended December 31,  1994
and 1995, all of the Company's sales of Prostate Materials were to one customer,
Pharma  Stroschein GmbH  ('Stroschein'). These  sales amounted  to approximately
$470,000 and $1,023,000, respectively, and represented approximately 66% and 18%
of the  net sales  of the  Company for  the years  ended December  31, 1994  and
December  31, 1995, respectively. In addition,  for the years ended December 31,
1994 and 1995, and the three months ended March 31, 1996, the Company's sales of
oncological products to Medac amounted  to approximately $214,000, $670,000  and
$210,000,   respectively  and  represented  approximately   30%,  12%  and  11%,
respectively of the net sales. On a pro forma basis, giving effect to the Bioren
Acquisition as if the transaction occurred on January 1, 1995, the 1995 sales to
Stroschein and Medac represented approximately 12% and 8%, respectively, of  the
Company's  sales. The loss of either of these customers or any other significant
customer would have a material adverse effect on the Company.
    
 
     DEPENDENCE ON  KEY  SUPPLIERS. The  majority  of raw  materials  needed  to
manufacture  the  Company's products  and  proposed products  generally  are not
readily available and must be purchased  from limited sources. In addition,  the
Company   obtains  containers  for  IV  Solutions  from  a  sole  supplier.  See
' -- Reliance on  PLM.' The Company's  reliance on a sole  or limited number  of
suppliers  involves several risks, including obtaining an adequate supply of raw
materials and components in order to manufacture or market products or  proposed
products,  increased raw  material or component  costs and  reduced control over
pricing, quality and  timely delivery.  Any interruption  in the  supply of  raw
materials  or components could have a material adverse effect on the Company. In
addition, obtaining  raw materials  from  a new  source may  require  regulatory
approval.   Furthermore,  certain  potential   alternative  suppliers  may  have
pre-existing exclusive relationships with competitors of the Company and  others
which  may  preclude  the Company  from  manufacturing certain  of  its proposed
products. See 'Business -- Manufacturing and Suppliers.'
 
   
     MANUFACTURING FACILITIES  FOR  PROPOSED PRODUCTS  UNDER  CONSTRUCTION.  The
Company  intends  to manufacture  cytotoxic oncological  products in  the Bigmar
Facility and  non-cytotoxic oncological  products  in a  dedicated area  of  the
Bioren  Facility,  where  it  currently manufactures  IV  Solutions.  The Bigmar
Facility  is  currently  being   equipped  and  the   Company  will  not   begin
manufacturing  oncological products until the  facility is fully operational and
regulatory approvals are obtained, which the Company believes will occur in  the
last  quarter of 1996. The Company intends to  use a portion of the net proceeds
from the Offering to equip a dedicated  area of the Bioren Facility and  expects
that the area for manufacturing non-cytotoxic oncological products will be fully
operational  and that all  regulatory approvals will  be obtained by  the end of
1996. There can be no assurance that  the Bigmar Facility or the dedicated  area
of  the  Bioren Facility  will be  successfully  equipped, that  the anticipated
regulatory approvals  will be  obtained or  that  the Company  will be  able  to
manufacture  these  products directly  and any  failure  to do  so would  have a
material adverse  effect on  the Company.  The Company  may have  to enter  into
contractual  arrangements  with  other  companies  to  manufacture  its proposed
oncological products. Further, the  Company intends to  enter into an  agreement
with  another party pursuant to which  that company will manufacture recombinant
urokinase. The amount of resources and the time that the other party will devote
towards  producing  recombinant   urokinase  on  behalf   of  the  Company   and
manufacturing  procedures and quality  control will not  be within the Company's
control. In addition, there can be no assurance that the Company will be able to
enter into any arrangements with third  parties on acceptable terms, if at  all,
or  that any  third party  will be  able to  meet the  demand for  the Company's
products on  a  timely basis  or  that other  parties  will meet  the  standards
required  to  obtain regulatory  approvals. See  'Business --  Manufacturing and
Suppliers and -- Facilities.'
    
 
     NO ASSURANCE  OF  SUCCESSFUL  PRODUCT DEVELOPMENT;  UNCERTAINTY  OF  MARKET
ACCEPTANCE  OF CERTAIN PROPOSED PRODUCTS. Although the Company currently markets
certain  oncological   products,   it   has  not   sold   any   oncological   or
biotechnological products manufactured at its facilities and does not anticipate
manufacturing  oncological  products  until  the  end  of  1996.  Any unexpected
developmental,  regulatory   or   manufacturing   problems   could   delay   the
commercialization of the Company's proposed products and
 
                                       10
 <PAGE>
<PAGE>
have  a material adverse effect  on the Company and  its prospects. In addition,
the market acceptance of any of the Company's proposed products, such as  sodium
leucovorin  and recombinant  urokinase, will  be substantially  dependent on the
ability of  the  Company's  collaborators  to demonstrate  to  the  medical  and
healthcare communities the capabilities, perceived benefits, and efficacy of the
Company's  proposed  products  as  well as  sell  commercial  quantities  of the
proposed products  at acceptable  costs.  There can  be  no assurance  that  the
Company will be able to ultimately successfully develop its proposed products or
that  it will be able  to gain market acceptance  for its proposed products. See
'Business -- Proposed Products and -- Other Proposed Products.'
 
     NEED FOR ADDITIONAL  FINANCING. The  Company has funded  its operations  to
date  primarily through equity and debt financings. The Company anticipates that
the net proceeds from the Offering, together with cash flow from operations  (if
any),  should  be sufficient  to fund  the  Company's operations,  including its
proposed expansion,  for  approximately 12  months.  However, there  can  be  no
assurance  that events affecting the Company's operations will not result in the
Company depleting its  funds before  that time. The  Company may  need to  raise
substantial  additional  funds to  continue to  fund  operating expenses  or its
expansion strategy. There can be no assurance that additional financing will  be
available,  or, if available, that such financing  will be on terms favorable to
the Company. Failure to obtain such  additional financing would have a  material
adverse  effect on the Company. See  'Use of Proceeds,' 'Management's Discussion
and Analysis of Financial Condition and  Results of Operations -- Liquidity  and
Capital Resources' and the Company's financial statements and notes thereto.
 
   
     SUBSTANTIAL INDEBTEDNESS DUE AFTER 1997. At March 31, 1996, the Company had
an  aggregate of  $12,686,626 in outstanding  indebtedness, including $1,847,184
which is  payable  from the  net  proceeds of  the  Offering and  $1,071,821  of
accounts  payable to equipment vendors which the Company intends to pay with the
proceeds  of  its  existing  credit  facilities.  Of  such  total  indebtedness,
$4,846,977  (or 38%)  is governed  by contractual  arrangements which  expire on
December  31,  1997  and  $2,518,892   (or  20%)  is  governed  by   contractual
arrangements  which expire on May 17, 1999. After such dates, $4,846,977 of such
loans are  automatically due  and  $2,518,892 are  payable  upon demand  if  the
Company  does  not  renegotiate  these  arrangements.  The  Company  intends  to
renegotiate the terms of the  Bigmar Pharmaceuticals loans (including  extending
the  term of the loans) upon completion of  the Bigmar Facility and the terms of
the Bioren  loan prior  to  its due  date  (May 17,  1999).  The holder  of  the
indebtedness has advised the Company that it is prepared to negotiate extensions
of  the loans  upon expiration. In  the event  the Company is  not successful in
renegotiating the terms of the loans, there  can be no assurance that the  loans
will  not become due.  In addition, there  can be no  assurance that the Company
will be able to renegotiate the terms of indebtedness on favorable terms to  the
Company  or at all. The  failure of the Company  to renegotiate the indebtedness
would have  a  material  adverse  effect upon  the  Company.  See  'Management's
Discussion  and Analysis  of Financial Condition  and Results  of Operation' and
'Business -- Facilities.'
    
 
   
     COMPETITION  AND  RAPID  TECHNOLOGICAL   CHANGE.  The  pharmaceutical   and
biotechnology  industries  are  subject  to intense  competition  and  rapid and
significant technological  change.  The  Company faces  competition  from  other
pharmaceutical  and biotechnology companies,  particularly regarding its generic
products, many of which have substantially greater financial and other resources
than the Company  and, therefore, are  able to  spend more than  the Company  in
areas  such  as product  development,  manufacturing and  marketing.  Although a
company with greater resources will not necessarily receive regulatory  approval
for  a  particular  generic  drug before  its  smaller  competitors, substantial
resources  enable   a   company   to  support   many   regulatory   applications
simultaneously, thereby improving the likelihood of at least some of its generic
drugs  being among the first to receive regulatory approval. Drug companies have
also increasingly introduced generic versions of their own proprietary  products
prior  to the  expiration of the  patents for  those drugs in  efforts to obtain
greater  market  share  following  expiration  of  the  applicable  patents.  In
addition,  the  market  for  the Company's  products  and  proposed  products is
characterized by  frequent product  improvements  and evolving  technology.  The
Company's   revenues   and  profitability   could   be  adversely   affected  by
technological change.  Competitors may  develop products  which may  render  the
Company's products or proposed products uneconomical or result in products being
commercialized  that may  be superior  to the  Company's products.  In addition,
alternative treatments  for  cancer  could  be developed,  which  would  have  a
material adverse effect on the
    
 
                                       11
 <PAGE>
<PAGE>
Company.  See 'Business -- Proposed Products,  -- Competition and -- Patents and
Proprietary Rights' and 'Governmental Regulations.'
 
     UNCERTAIN PROTECTION OF PATENTS AND PROPRIETARY RIGHTS. The Company  relies
on a combination of patent applications, licenses, trademarks, and trade secrets
to  protect its  proprietary technology, rights  and know-how.  In addition, the
Company is currently in the process  of implementing a policy that requires  its
personnel  to execute non-disclosure agreements. There  can be no assurance that
such patent applications or any resulting patents or any licenses or  trademarks
will  not be infringed upon, that the Company's trade secrets will not otherwise
become known to or independently  developed by competitors, that  non-disclosure
agreements  will  not  be breached,  or  that  the Company  would  have adequate
remedies for any  such infringement or  breach. Litigation may  be necessary  to
enforce  proprietary  rights of  the Company  or to  defend the  Company against
third-party claims of infringement. Such litigation could result in  substantial
cost  to, and a diversion  of effort by, the Company  and its management and may
have a material  adverse effect  on the Company.  The Company  currently is  the
exclusive and non-exclusive licensee of various oncological and biotechnological
products  and technologies and may in the future desire or be required to obtain
other licenses to develop, manufacture and market commercially viable  products.
The  Company's success and potential competitive advantage is dependent upon its
ability to  exploit  the  technology  under these  licenses.  There  can  be  no
assurance  that the Company  will be able  to exploit the  technology covered by
these license  agreements or  that it  will be  able to  do so  exclusively.  In
addition,  there can  be no  assurance that  any patents  or patent applications
pursuant to which the Company has  obtained licenses are valid and  enforceable,
or  that any licenses required to be obtained  by the Company in the future will
be valid and enforceable or obtainable  on commercially reasonable terms, if  at
all.
 
     Patents  concerning pharmaceutical  or biotechnological  products generally
are highly uncertain,  involve complex legal,  scientific and factual  questions
and  have recently been the  subject of much litigation.  To date, no consistent
policy has emerged  regarding the  breadth of claims  allowed or  the degree  of
protection  afforded under these patents. Accordingly, there can be no assurance
that patent applications which  underlie the Company's  licenses will result  in
patents  being issued,  or that, if  issued, the patents  will afford protection
against competitors with similar technology.  Although the Company is not  aware
of any claim against it for infringement, the Company's ability to commercialize
its  products and proposed products depends on is not infringing the proprietary
rights  of  competitors.  Laws  regarding  the  enforceability  of  intellectual
property vary from country to country. Therefore, there can be no assurance that
intellectual property issues will be uniformly resolved, or that local laws will
provide  the Company with consistent rights and benefits. In addition, there can
be no assurance that  competitors will not be  issued patents which may  prevent
the manufacturing or marketing of the Company's products or proposed products or
require  licensing and the payment of fees  or royalties by the Company in order
for the  Company to  be able  to  manufacture or  market certain  products.  See
'Business -- Patents and Proprietary Rights.'
 
     FDA,  INTERNATIONAL  AND OTHER  GOVERNMENTAL REGULATIONS.  The development,
manufacturing and marketing of the  Company's products and proposed products  is
or  may be  subject to  extensive and  rigorous governmental  regulations in the
United States  and other  countries. The  process of  obtaining and  maintaining
required  regulatory  approvals is  lengthy,  expensive, and  uncertain.  In the
United States, the United States Food and Drug Administration ('FDA') regulates,
where   applicable,   the   development,   testing,   labeling,   manufacturing,
registration,  notification,  clearance  or  approval,  marketing, distribution,
recordkeeping, and  reporting  requirements  for  drugs.  The  Company  has  not
requested  or received FDA  approval to market  any of its  products or proposed
products in the  United States. The  Company intends to  submit abbreviated  new
drug  applications ('ANDAs') to the FDA  for six generic oncological products in
the foreseeable future. The average time for obtaining FDA approval for ANDAs is
one to three years. However, due to management's prior experience in  submitting
ANDAs to the FDA, the Company believes it will be able to obtain FDA approval of
these  ANDAs in approximately  one year from  the date of  the submission of the
applications. There can  be no  assurance, however,  that any  of the  Company's
products  or  proposed  products will  obtain  regulatory approval  in  the time
periods indicated  or will  ever  obtain the  regulatory clearance  or  approval
required  for marketing in the United States. Delays in any part of the approval
process or the inability of the
 
                                       12
 <PAGE>
<PAGE>
Company to  obtain regulatory  approval of  its products,  proposed products  or
facilities could adversely affect the Company.
 
     The  Company  will be  subject to  the  FDA's good  manufacturing practices
('GMP'), good  laboratory practices  ('GLP') and  extensive record  keeping  and
reporting requirements for manufacturing products for sale in the United States.
As  a result, the Company's manufacturing facilities will be subject to periodic
inspections by  the  FDA and  other  United  States federal  agencies  when  the
Company's  products are  offered for  sale in  the United  States. The Company's
operations have not yet been inspected by the FDA and there can be no  assurance
they  will pass any inspections by the FDA. The Company has retained independent
consultants to  assist it  in complying  with FDA  standards including  the  GMP
requirements.  Failure  to comply  with  applicable regulatory  requirements can
result in,  among  other  things, import  detentions,  fines,  civil  penalties,
suspensions  or losses of approvals, recalls  or seizures of products, operating
restrictions and criminal prosecutions.
 
     To date, substantially all of the Company's revenues have been derived from
the sales  of  its  products  in  Switzerland,  Lichtenstein  and  Germany.  The
distribution  of the Company's products and proposed products outside the United
States is  subject to  extensive  governmental regulations.  These  regulations,
including  the requirements  of inspections  and approvals  to market,  the time
required for regulatory review  and the sanctions  imposed for violations,  vary
from  country to country. There  can be no assurance  that the Company will pass
any such  inspections, that  the Company  or its  collaborators will  obtain  or
maintain the required regulatory approvals in any particular country or that the
Company  will  not  be  required  to incur  significant  costs  in  obtaining or
maintaining its  regulatory approvals.  Failure to  obtain necessary  regulatory
approvals,  the restriction, suspension  or revocation of  existing approvals or
any other failure to comply with  regulatory requirements would have a  material
adverse effect on the Company.
 
     Because  the  Company's  products  are currently  being  sold  primarily in
Germany, Switzerland and Lichtenstein, the  Company is subject to regulation  by
these  countries, and the  European Medicines Evaluation  Agency ('EMEA') of the
European Union ('EU'). In Germany, drugs for human use may be sold only if  they
are  approved in  advance by  either the German  regulatory authority  or the EU
after a  review  of  all  applicable safety,  quality  and  effectiveness  data.
Clinical  trials  in Germany  are monitored  by the  state authorities  and must
comply with those portions of the EU good clinical practices recommendation that
have been adopted into  German law. In practice,  it takes the German  authority
generally  three to five years to approve  drugs for use on humans, although the
Company believes it will receive regulatory approval for certain of its proposed
products earlier.
 
     In January  1995, the  EU established  new procedures  that provide  for  a
compulsory  review of  biotechnological preparations  and an  optional review of
certain other pharmaceutical products by the EMEA in London. For other types  of
products, there is a decentralized procedure under which a marketing application
is  submitted first to one EU member  state where it is reviewed. Once marketing
approval in  such  country is  obtained,  a  company can  then  file  additional
applications in the other EU member states.
 
     Although  recombinant urokinase is a  biotechnological product, the Company
believes that marketing clearance  will be obtained in  the second half of  1997
from  the  German  regulatory authority  as  opposed  to from  the  EMEA because
recombinant urokinase does  not pose  a risk  of viral  contamination and  would
replace  the  naturally derived  urokinase that  is currently  on the  market in
Germany. There can  be no  assurance, however,  that the  requisite approval  of
recombinant  urokinase will be obtained in  Germany, that approval from the EMEA
in London will not be required, or that approval will be obtained in 1997 or  at
any time thereafter.
 
     In  Switzerland, approval of the production and sale of drugs for human use
is regulated on a  cantonal level rather  than a federal  level. The cantons  of
Switzerland   have  organized  the  Intercantonal  Office  for  the  Control  of
Medications ('IKS') as an authority  for the approval of pharmaceuticals.  Based
on approval by the IKS, the cantons then grant permission for the production and
sale of such approved pharmaceuticals, although each canton is still entitled to
deny approval of a particular medication.
 
     The IKS reviews all applicable safety, quality and efficacy data as well as
data  relating  to the  cost effectiveness  of a  particular product.  To obtain
approval from the IKS, the manufacturer must submit
 
                                       13
 <PAGE>
<PAGE>
analytical, chemical,  pharmacological and  toxicological data  based on  animal
trials  and human clinical studies. The  IKS also will inspect the manufacturing
facility to determine if the  manufacturer is complying with good  manufacturing
practices  before approval is  granted to produce the  drug product. For generic
products, pharmacological and toxicological data is not required to be submitted
to the IKS.  To date, all  of the Company's  pharmaceutical products which  have
been  approved  by the  IKS are  generic  products. There  can be  no assurance,
however, that the  Company will  obtain the  requisite approvals  to market  its
proposed  products in Switzerland in  the time periods indicated  or at any time
thereafter. See 'Business -- Governmental Regulations.'
 
     RESTRICTIONS ON RETAINED  EARNINGS. The Company  is a Delaware  corporation
which  owns  100% of  the capital  stock  of two  Swiss corporations.  The Swiss
Federal Code of Obligation provides  that at least 5%  of a Swiss company's  net
income  each year must be appropriated to a legal reserve until such time as the
reserve equals 20% of the company's  paid-in share capital. In addition, 10%  of
any  distribution made  by a  company in excess  of a  5% dividend  also must be
appropriated to the Company's  legal reserve. The  reserve of up  to 50% of  the
share   capital  is  not  available  for  distribution  to  stockholders.  These
requirements may adversely impact  the amount of dividends  to be issued by  the
Company  through its subsidiaries and may limit cash flow. See 'Dividend Policy'
and 'Management's Discussion and Analysis of Financial Condition and Results  of
Operations.'
 
     ENVIRONMENTAL  MATTERS.  As  an enterprise  engaged  in  the pharmaceutical
business in Switzerland,  the Company's  facilities are  or will  be subject  to
comprehensive  environmental laws and regulations governing, among other things,
air emissions, waste  water discharge  and solid and  hazardous waste  disposal.
Although  there can be no assurance, the Company believes its current facilities
are in compliance in all  material respects with applicable Swiss  environmental
laws.  However, environmental laws have changed  in recent years and the Company
may become  subject to  increasingly stringent  environmental standards  in  the
future.  While the  Company anticipates  that from  time to  time it  will incur
capital expenditures in connection with  environmental matters, it is unable  to
predict  the extent or  timing of future  expenditures which may  be required in
connection with complying  with environmental  laws. There can  be no  assurance
that  future developments,  administrative actions  or liabilities  arising from
environmental matters will not  have a material adverse  effect on the  Company.
See 'Business -- Environmental Regulations.'
 
     DEPENDENCE ON THIRD-PARTY REIMBURSEMENT; PRICE CONTROLS; HEALTH CARE REFORM
MEASURES.  The Company's success in generating revenues from the sale of certain
products may depend on the extent to  which reimbursement for the costs of  such
products  and related treatments will be  available from third-party payors such
as government health  administration authorities,  private insurance  companies,
self-insured    employers,   health   maintenance    organizations   and   other
organizations. The  level of  revenues and  profitability of  the Company,  like
those  of other companies in the  pharmaceutical and biotechnology industry, are
affected by the continuing  efforts of third-party payors  to contain or  reduce
the  costs of health care by lowering reimbursement or payment rates, increasing
case management review of services and negotiating reduced contract pricing  and
reimbursement caps.
 
     In  some markets outside of the  United States, such as Germany, government
reimbursement is generally available for the purchase of the Company's  products
and proposed products, subject to constraints such as reimbursement limitations.
In  addition, third-party  payors may refuse  to provide  reimbursement in cases
where  drugs,  such  as  oncological  drugs,  are  used  for  unapproved   uses.
Approximately  70%  of  the  drugs  sold  in  Germany  are  subject  to  maximum
reimbursement. To date, no oncological products have been affected by a  maximum
reimbursement  limitation, although there can be no assurance that the Company's
oncological products or  proposed products  will not  be affected  by a  maximum
reimbursement  limitation in  the future. Although  a manufacturer  may sell its
products at prices that are higher than the maximum reimbursement rate, patients
are  required  to  pay  any  difference  between  that  price  and  the  maximum
reimbursement  rate. If the products of the  Company become subject to a maximum
reimbursement rate, this  may adversely affect  the prices the  Company will  be
able to charge.
 
     In  Switzerland, reimbursement for pharmaceutical  products is regulated on
the federal level. There are two  categories of drugs subject to  reimbursement.
The  first category consists of medications  which are required to be reimbursed
by private  health  insurers.  The  second  category  contains  medications  for
 
                                       14
 <PAGE>
<PAGE>
which  reimbursement by health insurers  is recommended. Private health insurers
generally provide reimbursement for products on the recommended list. There  can
be  no assurance that payments under governmental and third-party payor programs
will remain at levels comparable  to present levels or  will, in the future,  be
sufficient  to cover the costs allocable  to patients eligible for reimbursement
pursuant to such programs.
 
     From time  to  time, the  Clinton  Administration, the  U.S.  Congress  and
legislators  of certain foreign  governments have proposed  or are considering a
variety of reforms to the health  care systems. The Company cannot predict  what
health  care reform legislation, if any, will be enacted in the United States or
elsewhere. Changes in the health care  system in the United States or  elsewhere
could  have a significant impact on the manner in which the Company conducts its
business and  may impose  additional regulations  governing the  conduct of  the
Company's  business. These changes  could have a material  adverse effect on the
Company. See 'Business -- Third-Party Reimbursement.'
 
     POTENTIAL PRODUCT  LIABILITY; AVAILABILITY  OF INSURANCE;  RISK OF  PRODUCT
RECALL.  The  testing,  clinical  trials, manufacturing,  and  marketing  of the
Company's products and proposed products  involve the inherent risks of  product
liability  claims or similar  legal theories against the  Company, some of which
may cause the Company to incur  significant defense costs. Although the  Company
currently  maintains product liability  insurance coverage which  it believes is
adequate, there can be  no assurance that the  coverage limits of its  insurance
are  adequate or that all such claims will be covered by insurance. In addition,
these policies generally must be renewed every two years. While the Company  has
been  able to obtain  product liability insurance  in the past,  there can be no
assurance it will be able to obtain  insurance in the future on its products  or
proposed  products. Product liability insurance varies  in cost, is difficult to
obtain and  may not  be  available in  the future  on  terms acceptable  to  the
Company,  if it  is available  at all. A  successful product  liability claim or
other judgment against  the Company in  excess of its  insurance coverage  could
have  a material adverse effect  upon the Company or  its reputation. Certain of
the  Company's   collaborative   arrangements  contain   cross   indemnification
provisions  with respect to product liability claims concerning products covered
by the arrangements. The Company may be required to make payments, which in some
cases could be substantial, under these arrangements. In addition, products such
as those sold or proposed to be sold by the Company may be subject to recall for
unforeseen reasons. Such a  recall could have a  material adverse effect on  the
Company and its reputation. In Germany, an injured party may recover for damages
on  a strict liability basis  without having to prove  negligence on the part of
the manufacturer or  distributor. In  Switzerland, there is  no special  product
liability  law  for pharmaceuticals.  The Swiss  federal product  liability law,
which covers drug products,  provides that manufacturers  are subject to  strict
liability  for injuries caused  by defective products.  See 'Business -- Product
Liability and Insurance.'
 
     UNCERTAINTY OF CURRENCY FLUCTUATIONS. All of the Company's revenues for the
fiscal years ended December  31, 1993, 1994  and 1995 and  for the three  months
ended  March 31,  1996 were  derived from  sales outside  of the  United States.
Because the Company's international operations are conducted in various  foreign
currencies,  it  may be  materially and  adversely  affected by  fluctuations in
currency exchange rates.  As a result,  the Company will  be exposed to  foreign
currency  exchange risks due  to fluctuations in the  exchange rates between the
foreign currencies  and  the  U.S.  dollar.  If  the  Company  executes  hedging
transactions  in the future, there can be  no assurance that the Company will be
successful in these  activities. See  'Management's Discussion  and Analysis  of
Financial   Condition  and  Results  of  Operations  --  Liquidity  and  Capital
Resources.'
 
   
     DEPENDENCE ON KEY PERSONNEL.  The Company is  dependent on the  experience,
abilities  and continued  services of  John G.  Tramontana, its  Chairman of the
Board, President and  Chief Executive Officer.  The Company has  entered into  a
five-year  employment  agreement  with  Mr.  Tramontana  which  begins  upon the
consummation of the Offering and expires  in 2001 and has obtained a  $2,000,000
key  man life insurance policy on the life of Mr. Tramontana, for the benefit of
the Company, effective June 15, 1996. The  loss or reduction of services of  Mr.
Tramontana or any other key employee could have a material adverse effect on the
Company.  In addition, the  Company's future success depends  in large part upon
its  ability  to  attract  and  retain  highly  qualified  personnel,  including
experienced  manufacturing  personnel. The  Company  faces competition  for such
personnel  from  other   companies  and  organizations,   many  of  which   have
significantly greater resources than the Company. There can be no assurance that
the  Company  will be  able to  attract  and retain  the necessary  personnel on
acceptable
    
 
                                       15

<PAGE>
terms or  at all.  See  'Management --  Directors,  Executive Officers  and  Key
Personnel and -- Employment Agreements.'
 
     CONTROL  OF  COMPANY.  Upon  consummation of  the  Offering,  the Company's
directors, executive officers and  existing stockholders will beneficially  own,
in  the  aggregate, approximately  2,375,000  shares of  the  outstanding Common
Stock, representing approximately  65.5% of  the issued  and outstanding  Common
Stock.  Accordingly, these  stockholders will  be in  a position  to control the
management and policies of the Company in general, and can determine the outcome
of any  corporate  transaction  or  other  matter  submitted  to  the  Company's
stockholders   for  approval  including  the  election  of  directors,  mergers,
acquisitions, consolidations or  the sale  of all  or substantially  all of  the
Company's  assets.  See  'Principal Stockholders'  and  'Description  of Capital
Stock.'
 
     ENFORCEABILITY OF CIVIL LIABILITIES AGAINST THE COMPANY. Substantially  all
of  the assets  of the Company  are located outside  of the United  States. As a
result, it  may be  difficult for  investors to  enforce judgments  against  the
Company  obtained in United States courts  including judgments predicated on the
civil liability  provisions of  the United  States securities  laws. The  United
States does not currently have a treaty providing for reciprocal recognition and
enforcement  of judgments  in civil and  commercial matters  with Switzerland or
Germany and there is doubt whether (i) a final judgment for the payment of money
rendered by  a Federal  or  state court  in the  United  States based  on  civil
liability,  whether or not predicated solely upon the civil liability provisions
of the United  States securities laws,  would be enforceable  in Switzerland  or
Germany  against the Company and (ii) an  action could be brought in Switzerland
or Germany against the Company in the  first instance on the basis of  liability
predicated solely upon the provisions of the United States securities laws.
 
     ABSENCE  OF  PUBLIC MARKET;  DETERMINATION  OF OFFERING  PRICE; VOLATILITY.
Prior to the Offering, there has been no public trading market for the Company's
Common Stock and there can  be no assurance that  an active trading market  will
develop  following the Offering or, if developed, will be sustained. The initial
public offering price  of the Common  Stock will be  determined by  negotiations
between  the Company and the Representative. There  can be no assurance that the
Common Stock will  trade in the  public market  at or above  the initial  public
offering  price following the consummation of the Offering. The trading price of
the Common Stock  could be subject  to significant fluctuations  in response  to
variations   in  quarterly  operating   results  and  other   factors  and  such
fluctuations could  cause the  market price  of the  Common Stock  to  fluctuate
substantially.  In addition, the  stock markets in the  United States have, from
time to time,  experienced significant  price and volume  fluctuations that  are
unrelated  or  disproportionate  to  the  operating  performance  of  individual
companies. Such fluctuations may adversely affect the price of the Common Stock.
See 'Management's Discussion and Analysis of Financial Condition and Results  of
Operations' and 'Underwriting.'
 
     LACK  OF UNDERWRITING HISTORY. The Representative was organized in February
1992 and first registered  as a broker-dealer in  1993. Prior to this  Offering,
the  Representative has  participated as  a sole  or co-manager  in three public
offerings. Prospective  purchasers of  the Common  Stock offered  hereby  should
consider  the lack of experience of the  Representative in being a manager of an
underwritten public offering. See 'Underwriting.'
 
   
     CONTINUED QUOTATION ON  THE NASDAQ SMALLCAP  MARKET.SM Subject to  official
notice  of issuance, the Company has received  approval to have the Common Stock
quoted on  the  Nasdaq SmallCap  MarketSM  upon consummation  of  the  Offering.
However,  there can be no assurance that it will be able to satisfy the criteria
for continued quotation on the Nasdaq SmallCap MarketSM following the  Offering.
Failure  to meet the maintenance criteria in the future may result in the Common
Stock not  being eligible  for  quotation on  the  Nasdaq SmallCap  MarketSM  or
otherwise.  In such event, an investor may find it more difficult to dispose of,
or to obtain accurate quotations  as to the market  value of, the Common  Stock.
See 'Description of Capital Stock.'
    
 
     POSSIBLE  ADVERSE  EFFECTS OF  ISSUANCE  OF PREFERRED  STOCK; ANTI-TAKEOVER
PROVISIONS. The  Company's Restated  and  Amended Certificate  of  Incorporation
('Restated  Certificate')  authorizes the  issuance  of a  maximum  of 5,000,000
shares of preferred stock, par value  $.001 per share ('Preferred Stock'),  with
designations,  rights and  preferences as  determined from  time to  time by the
Board of Directors. As  a result of  the foregoing, the  Board of Directors  can
issue,  without  further stockholder  approval,  Preferred Stock  with dividend,
liquidation, conversion, voting or other rights that could
 
                                       16
 <PAGE>
<PAGE>
adversely affect the voting power or other  rights of the holders of the  Common
Stock.  The  issuance of  Preferred  Stock could,  under  certain circumstances,
discourage, delay or prevent  a change in control  of the Company. In  addition,
the issuance of Preferred Stock could dilute the rights of holders of the Common
Stock  and the  market price of  the Common  Stock. Although the  Company has no
plans to issue any shares of Preferred Stock, there can be no assurance that  it
will  not issue Preferred  Stock at some  future date. Upon  consummation of the
Offering, the  Company  will be  subject  to Delaware  General  Corporation  Law
('DGCL')  provisions  that  prohibit  the  Company  from  entering  into certain
business combinations without  the approval of  its Board of  Directors and,  as
such,  could  prohibit or  delay  mergers or  other  transactions or  changes in
control  with  respect  to  the  Company.  Such  provisions,  accordingly,   may
discourage attempts to acquire the Company. See 'Description of Capital Stock --
Preferred Stock and -- Delaware Anti-Takeover Law.'
 
     SHARES  ELIGIBLE  FOR FUTURE  SALE; EXERCISE  OF REGISTRATION  RIGHTS. Upon
consummation of the  Offering, there will  be 3,625,000 shares  of Common  Stock
outstanding,   of  which  2,375,000  shares  of  Common  Stock  are  'restricted
securities' under Rule  144 under the  Securities Act of  1933, as amended  (the
'Securities  Act'),  and (except  for shares  purchased  by 'affiliates'  of the
Company as such term is defined in Rule  144) would be eligible for sale in  May
1998,  without regard  to lock-up restrictions  with the  Representative. In the
future, the  2,375,000  shares may  be  sold  only pursuant  to  a  registration
statement  under  the  Securities  Act  or  an  applicable  exemption, including
pursuant to Rule 144. Under Rule 144, a person who has owned Common Stock for at
least two years may,  under certain circumstances,  sell within any  three-month
period,  a number of shares of Common Stock  that does not exceed the greater of
1% of the then outstanding shares of Common Stock or the average weekly  trading
volume  during the four calendar weeks prior to such sale. In addition, a person
who is not deemed to  have been an affiliate of  the Company at any time  during
the three months preceding a sale, and who has beneficially owned the restricted
securities  for the last three years is entitled to sell all such shares without
regard to  the  volume  limitations, current  public  information  requirements,
manner  of sale provisions and notice  requirements. Sales or the expectation of
sales of a substantial  number of shares  of Common Stock  in the public  market
following  this Offering could  adversely affect the  prevailing market price of
the Common  Stock. The  Securities and  Exchange Commission  ('Commission')  has
proposed  an amendment to Rule 144 which  would reduce the holding period before
shares subject to Rule 144 become eligible  for sale in the public market.  This
proposal,  if  adopted, could  substantially increase  the  number of  shares of
Common Stock  eligible  for sale  following  the lock-up  restriction  described
immediately below.
 
     The  Company  and its  officers, directors  and existing  stockholders have
agreed with the Representative  not to directly  or indirectly register,  issue,
offer,  sell, offer to sell, contract  to sell, hypothecate, pledge or otherwise
dispose of any  shares of Common  Stock (or any  securities convertible into  or
exercisable or exchangeable for shares of Common Stock) for a period of one year
from  the date  of this  Prospectus, without  the prior  written consent  of the
Representative, subject to  certain exceptions. See  'Underwriting' and  'Shares
Eligible for Future Sale.'
 
     The holders of the Representative's Warrants have been granted registration
rights  with  respect  to  the  125,000 shares  issuable  upon  exercise  of the
Representative's  Warrants.  The  sale,  or   availability  for  sale,  of   the
outstanding  Common Stock underlying the Representative's Warrants in the public
market subsequent to the Offering  could adversely affect the prevailing  market
price  of  the Common  Stock and  could  impair the  Company's ability  to raise
additional capital. See  'Description of Capital  Stock -- Registration  Rights'
and 'Shares Eligible for Future Sale.'
 
     IMMEDIATE AND SUBSTANTIAL DILUTION; NO DIVIDENDS ANTICIPATED. Purchasers of
shares  of the Common Stock offered  hereby will incur immediate and substantial
dilution of the net tangible book value  of the Common Stock of $4.88 per  share
(or  61%) from the assumed initial public  offering price of $8.00 per share. In
addition, an immediate  increase in  the Company's  net tangible  book value  of
$1.85  per share to the existing  shareholders will result upon the consummation
of  the  Offering.  Thus,  the  net  tangible  book  value  per  share  will  be
significantly  lower than the price per share  paid by the public investors. The
Company has never paid any dividends on its Common Stock and does not anticipate
the payment  of dividends  in  the foreseeable  future. See  'Dividend  Policy,'
'Dilution' and 'Description of Capital Stock.'

                                  THE COMPANY
 
   
     The Company is currently engaged in manufacturing and marketing 14 types of
IV  Solutions in Switzerland and Lichtenstein  and marketing in Germany Prostate
Materials and  two  generic  oncological products,  mercaptopurine  and  calcium
leucovorin.  Over the next 24 months,  the Company's strategy is to manufacture,
in  its  state-of-the-art   facilities  in  Switzerland,   and  market   generic
oncological  drugs. In addition, the  Company is in the  process of preparing to
market certain licensed proprietary oncological and biotechnological products.
    
 
   
     The Company markets IV Solutions through its own sales force to health care
providers and third-party payors and markets Prostate Materials,  mercaptopurine
and  calcium leucovorin to pharmaceutical companies. The Company does not intend
to market its other products directly to the public. For the year ended December
31, 1995, on a pro forma basis after giving effect to the Bioren Acquisition  as
if  the transaction had occurred  on January 1, 1995,  the Company's sales of IV
Solutions and  antibiotics were  approximately $6.5  million, sales  of  medical
products,  including Prostate  Materials, were  approximately $1.4  million, and
sales of generic oncological products were approximately $670,000. For the three
months ended March 31,  1996, sales of  these products aggregated  approximately
$1.4 million, $319,000 and $210,000, respectively.
    
 
     The  Company was incorporated  in Delaware in September  1995 and has three
wholly-owned  subsidiaries,  Bigmar  Pharmaceuticals,  Bigmar  Therapeutics  and
Bioren. Bigmar Pharmaceuticals is a Swiss corporation that was formed in January
1992  under the name BVI, SA. Bigmar Therapeutics is a Delaware corporation that
was formed in  September 1995  under the  name Bioren,  Inc. Bioren  is a  Swiss
corporation that was formed in July 1986.
 
     In  June 1995, all of the outstanding capital stock of Bioren was purchased
by Bigmar Pharmaceuticals in the  Bioren Acquisition, for an aggregate  purchase
price of approximately $9.4 million, consisting of approximately $5.2 million in
cash  and the assumption of certain of the seller's liabilities in the aggregate
principal amount of  $4.2 million. In  addition, in connection  with the  Bioren
Acquisition,  Bigmar Pharmaceuticals became a guarantor on a bank loan to Bioren
in the principal amount of $2.6 million, which was collateralized by the  Bioren
Facility,  and  provided  a guarantee  on  a  second mortgage  in  the aggregate
principal amount  of  approximately $1.7  million  on the  Bioren  Facility.  In
addition,  in  June 1995,  Bigmar Pharmaceuticals  sold  one-half of  its equity
interest in Bioren  to Bigmar Pharmaceuticals'  stockholders ('Bioren  Holders')
for approximately $2.6 million. See 'Certain Transactions.'
 
     In  September 1995,  the Company sold  an aggregate of  2,375,000 shares of
Common Stock to  its existing  stockholders and on  April 8,  1996 the  existing
stockholders  contributed 99% of these shares of  Common Stock to the Company in
the Contribution. On April 9, 1996, in the Exchange, all of the stockholders  of
Bigmar  Pharmaceuticals exchanged  all their shares  of capital  stock in Bigmar
Pharmaceuticals for an  aggregate of  2,000,938 shares  of Common  Stock of  the
Company  and all of the Bioren Holders  exchanged all of their shares of capital
stock in  Bioren for  an aggregate  of 350,312  shares of  Common Stock  of  the
Company. See 'Certain Transactions.'

                                USE OF PROCEEDS
 
   
     The  net proceeds to the  Company from the sale  of the 1,250,000 shares of
Common Stock  offered  hereby, after  deduction  of underwriting  discounts  and
commissions,  Offering expenses  including the  Representative's non-accountable
expense  allowance,  will  be   approximately  $8,125,000  ($9,452,500  if   the
Underwriters'  over-allotment option is exercised  in full), assuming an initial
public offering price of  $8.00 per share.  The Company intends  to use the  net
proceeds  of the Offering  as follows: (i)  approximately $4,000,000 to acquire,
test and/or manufacture oncological and biotechnological products, including (a)
payments of up to $500,000 to Bioferment, pursuant to the Bioferment  Agreement,
and  up  to $100,000  to each  of Cernelle  and Sapec  pursuant to  the Cernelle
Agreement and the  Sapec Agreement, respectively,  (b) approximately  $1,000,000
for  the purchase of  equipment that will  be used to  manufacture the Company's
generic oncological products for which it will be seeking approvals from the FDA
and (c) approximately $400,000 to purchase  raw materials and pay for the  costs
incurred  in conducting stability and bioequivalence studies and clinical trials
for oncological and biotechnological products; (ii) approximately $1,850,000  to
repay  in full a working capital loan  originally assumed pursuant to the Bioren
Acquisition from Sigal  SA ('Sigal'),  a company  owned by  Galenica Holding  AG
('Galenica'),  the seller  of Bioren,  bearing interest  at the  rate of  6% and
payable to Galenica upon consummation  of the Offering; and (iii)  approximately
$2,275,000  for general corporate purposes,  including working capital. See 'The
Company' and 'Management's  Discussion and Analysis  of Financial Condition  and
Results of Operations.'
    
 
     John  G. Tramontana,  the Company's  Chairman of  the Board,  President and
Chief Executive Officer, was an officer and director of Cerbios Pharma, of which
Bioferment and Sapec are divisions, and the chairman of the board of Cernelle at
the time of the negotiation and execution of the Bioferment Agreement, the Sapec
Agreement  and  the  Cernelle  Agreement.  See  'Risk  Factors  --  Reliance  on
Collaborative  Arrangements;  Management  Affiliations  with  Collaborators' and
'Certain Transactions -- Transactions with Principal Stockholders.'
 
     The foregoing represents the  Company's estimate of  its allocation of  the
net  proceeds from  the Offering.  The actual cost,  timing and  amount of funds
required for  any particular  project  may vary  depending on  numerous  factors
including  the rate of the Company's progress  in the development of some of its
proposed products,  the results  of clinical  trials, the  timing of  regulatory
approvals,  the  amount and  timing of  payments under  collaborative agreements
entered into  by  the Company,  the  activities  of competitors,  the  costs  in
prosecuting or defending patent claims or license rights and other factors.
 
     Pending  application of the net proceeds  of the Offering, the Company will
make temporary investments in interest-bearing savings accounts, certificates of
deposit,  money  market  accounts  established  by  major  commercial  banks  or
financial  institutions,  United  States  government  obligations  or high-grade
commercial paper.  The  Company currently  intends  to use  any  additional  net
proceeds   that  it  may   receive  upon  the   exercise  of  the  Underwriters'
over-allotment option  to  reduce outstanding  indebtedness.  See  'Management's
Discussion    and   Analysis    of   Financial   Condition    and   Results   of
Operations -- Liquidity and Capital Resources.'
 
     The Company believes  that the  proceeds from the  Offering, together  with
cash flow from operations (if any), should be sufficient to fund its operations,
including  its proposed expansion,  for approximately 12  months. However, there
can be no  assurance that  events affecting  the Company's  operations will  not
result in the Company depleting its funds before that time. The Company may need
to  raise substantial additional funds to continue to fund operating expenses or
its expansion strategy.  The Company  may seek  this funding  through public  or
private  financings, corporate  collaborations or other  sources. However, there
can be no assurance that additional  financing will be available through any  of
these sources or, if available, that such financing will be on acceptable terms.
See 'Risk Factors -- Need for Additional Financing' and 'Management's Discussion
and  Analysis of Financial Condition and  Results of Operations -- Liquidity and
Capital Resources.'

                                DIVIDEND POLICY
 
     The Company has never paid cash dividends on its Common Stock and does  not
anticipate  paying dividends  in the  foreseeable future.  The Company currently
intends to retain future  earnings, if any, to  finance its expansion  strategy.
The  payment of future cash dividends by the Company on its Common Stock will be
at the discretion of  the Board of  Directors and will  depend on the  Company's
earnings  (if any), financial  condition, cash flows,  capital requirements, any
contractual prohibitions  with respect  to the  payment of  dividends and  other
considerations as the Board of Directors may consider relevant. In addition, the
Swiss  Federal Code of Obligation provides further restrictions on the Company's
ability to pay dividends to its stockholders. See 'Risk Factors --  Restrictions
on Retained Earnings.'

discounts and commissions and estimated Offering expenses payable by the Company
and  the  application  of a  portion  of  the net  proceeds  therefrom  to repay

                                    DILUTION
 
     At  March  31,  1996,  the  net tangible  book  value  of  the  Company was
$3,016,725, or  $1.27 per  share of  Common  Stock after  giving effect  to  the
Exchange  as if it had occurred on such  date. Net tangible book value per share
is determined by dividing tangible book value (total tangible assets less  total
liabilities)  by the number of shares of  issued and outstanding Common Stock at
that date. After giving  effect to the  sale of the  1,250,000 shares of  Common
Stock  offered hereby (at an assumed initial  public offering price of $8.00 per
share) and  the  application of  the  net proceeds  therefrom,  after  deducting
underwriting  discounts and commissions and Offering expenses, the pro forma net
tangible book value of the Company at March 31, 1996 would have been $11,314,299
or $3.12 per share. This represents  an immediate increase in net tangible  book
value  of $1.85 per share to existing  stockholders and an immediate dilution of
$4.88 per share to investors purchasing shares of Common Stock in the  Offering.
The following table illustrates this per share dilution:

                            SELECTED FINANCIAL DATA
 
     The  selected  financial data  presents historical  financial data  for (i)
Bioren SA (predecessor  company) for the  years ended December  31, 1991,  1992,
1993  and 1994 and for the six months ended June 30, 1995, and (ii) Bigmar, Inc.
for the years ended  December 31, 1992,  1993, 1994 and 1995  and for the  three
months  ended March 31, 1995 and 1996 (after giving effect to the reorganization
described in  Note 1  to  the Company's  financial statements).  The  historical
financial  data of Bioren and  Bigmar, Inc. has been  derived from the financial
statements (and  notes thereto)  of the  respective companies,  which  financial
statements  have been audited  by Richard A. Eisner  & Company, LLP, independent
auditors, included elsewhere in this Prospectus. The selected data presented  as
of  March 31, 1995  and 1996 and for  the three months ended  March 31, 1995 and
1996 are derived from  the unaudited financial statements  of the Company  which
appear  elsewhere in this Prospectus. In the opinion of management, the selected
financial data for  the three months  ended March  31, 1995 and  1996 have  been
prepared  on the same basis as the  audited financial statements and reflect all
adjustments, which are of a normal recurring nature, necessary to present fairly
the financial data for the periods presented. The results of operations for  any
interim  period  are  not necessarily  indicative  of the  Company's  results of
operations for the full fiscal year. The selected financial data should be  read
in  conjunction with the financial statements  (and notes thereto) of Bioren and
Bigmar, Inc. and  'Management's Discussion and  Analysis of Financial  Condition

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
     The  following discussion and  analysis should be  read in conjunction with
the  financial  statements  and  notes  thereto  appearing  elsewhere  in   this
Prospectus.
 
OVERVIEW
 
     The Company is currently engaged in manufacturing and marketing 14 types of
IV  Solutions in Switzerland and Lichtenstein  and marketing in Germany Prostate
Materials and  two  generic  oncological products,  mercaptopurine  and  calcium
leucovorin.  Over the next 24 months,  the Company's strategy is to manufacture,
in  its  state-of-the-art   facilities  in  Switzerland,   and  market   generic
oncological  drugs. In addition, the  Company is in the  process of preparing to
market certain licensed proprietary oncological and biotechnological products.
 
   
     The Company markets IV Solutions through its own sales force to health care
providers and third-party payors and markets Prostate Materials,  mercaptopurine
and  calcium leucovorin to pharmaceutical companies. The Company does not intend
to market its other products directly to the public. For the year ended December
31, 1995, on a pro forma basis after giving effect to the Bioren Acquisition  as
if  the transaction had occurred  on January 1, 1995,  the Company's sales of IV
Solutions and  antibiotics were  approximately $6.5  million, sales  of  medical
products,  including Prostate  Materials, were  approximately $1.4  million, and
sales of generic oncological products were approximately $670,000. For the three
months ended March 31,  1996, sales of  these products aggregated  approximately
$1.4  million, $319,000 and $210,000, respectively.  For the year ended December
31, 1995, approximately  $1.0 million  (or approximately 12%)  of the  Company's
sales  on a pro forma  basis were attributable to  sales of antibiotics. For the
three months ended March 31, 1996, approximately $145,000 (or approximately  8%)
of  the Company's sales were attributable to such products. Sales of antibiotics
have been progressively abandoned  by the Company, and  as a result the  Company
expects the percentage of sales attributable to antibiotic products for the year
ended  December 31, 1996 to be significantly  lower than the percentage of sales
for the prior year.
    
 
     The Company's revenues  and profitability  may be affected  by the  ongoing
efforts  of third-party payors to  contain or reduce the  costs of healthcare by
lowering reimbursement  payment  rates,  increasing case  management  review  of
services and negotiating reduced contract pricing and reimbursement caps. In the
event  any of the  Company's products become subject  to a maximum reimbursement
rate, the prices  the Company will  be able to  charge its customers  and, as  a
result  its  results  of  operations,  may  be  adversely  affected.  See  'Risk
Factors -- Dependence on Third-Party Reimbursement; Price Controls; Health  Care
Reform Measures.'
 
PLAN OF OPERATION
 
     The  Company  intends to  expand  its manufacturing  operations  to produce
generic oncological  products  in  its facilities  and  market  oncological  and
biotechnological  products to pharmaceutical companies for resale to the public.
The Company expects to begin marketing methotrexate and doxorubicin (two generic
oncological products)  to pharmaceutical  companies during  the second  half  of
1996.  In addition, the Company obtained the distribution rights to, among other
products, sodium  leucovorin and  five  generic oncological  products  including
methotrexate  and  calcium leucovorin  from Sapec  and approximately  20 generic
oncological  products   including   mercaptopurine,   calcium   leucovorin   and
methotrexate   from  Cernelle.  The  Company  anticipates  that  all  regulatory
approvals for the sale of sodium  leucovorin in Germany will be obtained  during
the  second  half of  1996 and  that the  marketing of  this product  will begin
shortly thereafter. There  can be  no assurance, however,  that such  regulatory
approvals  will be  obtained during these  time periods, or  that such approvals
will ever  be  obtained.  The Company  also  has  obtained the  rights  to  use,
manufacture  and market, among  other products, a  form of recombinant urokinase
from Bioferment. Although the Company does not intend to manufacture recombinant
urokinase, the Company anticipates that all regulatory approvals for the sale of
recombinant urokinase in Germany will be obtained during the second half of 1997
and that the marketing of this product will begin shortly thereafter. There  can
be no assurance, however, that such regulatory approvals will be obtained during
this  time period,  or at  all. The  Company's management  had affiliations with
Sapec, Cernelle and Bioferment at the  time of the negotiation and execution  of
the

agreements  with these parties.  See 'Risk Factors  -- Reliance on Collaborative
Arrangements; Management Affiliations with Collaborators' and
'Management -- Directors, Executive Officers and Key Personnel.'
 
     The Company's business strategy over the next 24 months is to:
 
           manufacture and market approximately seven injectable and lyophilized
           oncological products, including sodium leucovorin;
 
           manufacture and market additional oncological products as the patents
           relating to the products expire;
 
           increase the  number of  pharmaceutical companies  in Europe  through
           which  the  Company's  oncological  products  are  marketed  and  the
           territories in which they are distributed;
 
           market recombinant urokinase; and
 
           expand the  marketing  of IV  Solutions  in Switzerland  through  the
           Company's own sales force.
 
     The  Company has  entered into  exclusive arrangements  with non-affiliated
pharmaceutical companies to market  certain proprietary and generic  oncological
or  biotechnological products in various  territories. The following table lists
the generic oncological  products that  the Company intends  to manufacture  and
market  to pharmaceutical companies  for resale in  Switzerland, Germany and the
United States over the next  24 months and the  estimated time periods for  each
product.

     There  can be no assurance that the  Company will manufacture or market any
of the  foregoing products  during the  time periods  indicated or  at all.  The
commercialization  of  these  products  will  depend  on  a  number  of  factors
including, but not limited to, the successful results of the Company's  clinical
toxicity  studies  and  obtaining  regulatory  approval.  Although  the  Company
believes that each of these proposed products has commercial value, the  Company
may choose not to manufacture or market some or all of these products. See 'Risk

RESULTS OF OPERATIONS
 
BIGMAR, INC.
 
     Bigmar, Inc. was incorporated in September  1995. On April 9, 1996, in  the
Exchange,  Bigmar, Inc. acquired  100% of Bigmar Pharmaceuticals  and 50% of the
Bioren capital  stock owned  by  the Bioren  Holders. Accordingly,  both  Bigmar
Pharmaceuticals  and  Bioren are  100% owned  subsidiaries  of Bigmar,  Inc. The
acquisition was  accounted for  as a  reorganization of  companies under  common
control.  Accordingly, the financial statements of Bigmar, Inc. were restated to
include the  results of  Bigmar Pharmaceuticals  for all  periods presented  and
Bioren from July 1, 1995 (the date of acquisition).
 
BIGMAR THERAPEUTICS
 
     Bigmar  Therapeutics  was  incorporated  in  September  1995  and  its only
activity since inception  has been the  execution and delivery  of an  agreement
with  Protyde  Oncology Therapeutics,  Inc. ('Protyde  Therapeutics') to  form a
partnership, Protyde - Bigmar Therapeutics  ('Partnership'), for the purpose  of
coordinating  the manufacturing and marketing of certain pharmaceutical products
for the treatment of
 
                                       27

cancer,  such   as   mercaptopurine,  calcium   leucovorin,   methotrexate   and
doxorubicin, worldwide, except for certain major European countries.
 
BIGMAR PHARMACEUTICALS AND BIOREN
 
     Bigmar  Pharmaceuticals commenced operations in January 1992. The following
discussion and analysis describes the results  of operations of the Company  for
the  years ended December 31, 1993, 1994 and 1995 and Bioren from July 1, 1995 .
Effective June 30, 1995, Bigmar Pharmaceuticals acquired 100% of the outstanding
capital stock of Bioren in the  Bioren Acquisition, and immediately sold 50%  of
the  stock to the Bioren Holders. The Company's financial statements include the
results of Bigmar Pharmaceuticals for all periods presented and Bioren from July
1, 1995.
 
     Bioren  currently  manufactures  IV  Solutions  and  other   hospital-based
products.  Since the  Bioren Acquisition, sales  of IV  Solutions have increased
while sales  of  antibiotics (the  other  market in  which  Bioren  historically
operated)  have been progressively abandoned. In the near future, Bioren intends
to  continue  to  manufacture  and  market  IV  Solutions  and  expects  to  add
non-cytotoxic products used in the treatment of cancer.
 
     The  following sets forth, in tabular form,  a comparison of the results of
operations of the Company as a percentage  of the Company's sales for the  years
ended  December  31, 1993,  1994 and  1995 (including  the operating  results of
Bioren from July 1,  1995), and for  the three months ended  March 31, 1995  and
1996.  The fiscal  year of  the Company ends  on December  31 of  each year. The
financial information included in this Prospectus is not necessarily  indicative
of the Company's future operating results or financial condition.

</TABLE>
 
THREE MONTHS ENDED MARCH 31, 1996 COMPARED TO THREE MONTHS ENDED MARCH 31, 1995
 
     Net  Sales. Net  sales increased  by $712,292  to $1,898,002  for the three
months ended March 31, 1996 as compared to $1,185,710 for the comparable  period
in  1995. This  increase was  attributable to  the addition  of Bioren  sales of
$1,525,672 in 1996,  offset by a  decline of $813,380  in Bigmar  Pharmaceutical
sales  to $372,330. Bigmar Pharmaceuticals sales in 1995 were disproportionately
skewed in the first  quarter, as the  Company made two  large sales of  Prostate
Materials  amounting to  $1.0 million. Although  there can be  no assurance, the
Company expects to  generate similar sales  of Prostate Materials  for the  year
ended  December 31, 1996. Sales of other products, primarily calcium leucovorin,
increased in 1996 by approximately $200,000.  Bioren sales for the three  months
ended March 31, 1996 increased by $9,030 from the comparable period in 1995.
 
     Cost  of Goods Sold. Cost of goods  sold increased by $91,144 to $1,151,099
for the three  months ended March  31, 1996  as compared to  $1,059,955 for  the
comparable period in 1995. This increase was primarily due to increased sales.
 
     Gross  Profit. Gross profit increased by $621,148 to $746,903 for the three
months ended March 31,  1996 over the comparable  period in 1995. This  increase
was  attributable to the  addition of Bioren  gross profit in  1996 of $651,694,
partially offset by a decline in gross profit from Bigmar Pharmaceutical  sales.
Without the addition of Bioren, gross profit for the period ended March 31, 1996
declined by $30,547 to $95,208 as compared to $125,755 for the comparable period
in  1995. This decline was due to lower sales partially offset by improved gross
margins.  Gross   profit  on   Bioren   sales  for   the  three   months   ended
 
                                       28
 <PAGE>
<PAGE>
March  31, 1996 was $651,694, an increase  of $59,404 over the comparable period
in 1995. This increase was due to a more favorable product mix.
 
     As a percentage of sales, gross profit for the three months ended March 31,
1996 was 39.4%, an increase from 10.6% for the comparable period in 1995. Bigmar
Pharmaceuticals gross profit as  a percentage of sales  increased to 25.6%  from
10.6%  for the comparable period in 1995.  This improvement reflects a change in
the mix of products sold from period  to period as Prostate Materials were  sold
in  1995 at materially lower  margins than other products.  No sales of Prostate
Materials were made during the three  months ended March 31, 1996. Bioren  gross
profit  as  a percentage  of sales  for the  three months  ended March  31, 1996
increased to 42.7% from 39.1% for  the comparable period in 1995. This  increase
resulted  primarily from a reduced emphasis  on antibiotics in favor of infusion
products.
 
     Research and Development  Expenses. Research and  development expenses  for
the three months ended March 31, 1996 were $88,394, with no such expenses in the
comparable  period in  1995. The increase  reflects expenditures  related to the
formulation  and   development  of   oncology  and   related  products.   Bigmar
Pharmaceuticals  incurred  additional  expenditures  of  approximately  $300,000
during the three months ended March  31, 1996 related to equipment and  facility
validation  activities. These  expenditures were  deferred and  will be expensed
upon commencement of operations at the Bigmar Facility. Pursuant to its business
strategy,  the  Company  expects  to  significantly  expand  its  research   and
development  activities in order to obtain regulatory approval for manufacturing
and marketing oncology products.
 
     Selling,  General  and  Administrative   Expenses.  Selling,  general   and
administrative  expenses increased by $526,011 to  $547,463 for the three months
ended March 31, 1996 as compared to  $21,452 for the comparable period in  1995.
The  increase  was  due  to,  the  addition  of  Bioren's  selling,  general and
administrative   expenses   of   $499,418.   Bioren's   selling,   general   and
administrative  expenses  were  $553,734  in  the  comparable  period  in  1995.
Approximately 44%  of  Bioren's  selling, general  and  administrative  expenses
related to employee salaries and benefits.
 
     Interest  Expense. Interest  expense for the  three months  ended March 31,
1996 amounted to  $83,460 primarily due  to approximately $6.0  million of  debt
incurred  in  conjunction  with, and  assumed  in, the  Bioren  Acquisition. The
Company also incurred debt, aggregating approximately $5.3 million at March  31,
1996,  for  the construction  of the  Bigmar Facility  and validation  and other
facility start-up  activities. Interest  on  these borrowings  of  approximately
$62,000  was  capitalized  in  the  three  months  ended  March  31,  1996.  See
' -- Liquidity and Capital Resources.'
 
     Other Income (net). Other income for the three months ended March 31,  1996
was  $24,095, an increase of $116 over  Bioren's other income for the comparable
period in 1995. This income represents  payments to Bioren from a company  which
leases a portion of the Bioren Facility on a year-to-year basis.
 
     Income  Taxes. The Company is a Delaware corporation which owns 100% of the
capital stock of  two Swiss corporations.  The tax charge  in Switzerland is  an
accumulation  of  taxes  due  to  the  city,  canton  (state)  and  the  federal
authorities.  While  the  actual  rate  is  a  function  of  the  percentage  of
profitability  in relation to taxable equity, the Company believes that 20% is a
fair approximation  of  the effective  accumulative  rate. Swiss  law  precludes
consolidated  tax filings and thus  the ability to offset  taxable income in one
entity by losses of another. The tax liability for the three months ended  March
31,  1996 is not significant, particularly  because the Company's income for the
period was generated by Bioren which has a significant tax loss carry-forward.
 
     Net Income. The  consolidated net income  of $51,681 for  the three  months
ended  March 31, 1996 represents a decline of $39,090 from the comparable period
in 1995 and was primarily attributable to higher interest expense.
 
YEAR ENDED DECEMBER 31, 1995 COMPARED TO YEAR ENDED DECEMBER 31, 1994
(INCLUDING BIOREN FOR THE PERIOD FROM JULY 1, 1995 TO DECEMBER 31, 1995)
 
     Net Sales. Net  sales increased by  $4,892,735 to $5,600,362  for the  year
ended  December 31, 1995 as compared to $707,627 for the year ended December 31,
1994. Excluding Bioren  sales, the increase  in net sales  was $1,350,745,  from
$707,627  in 1994 to $2,058,372 in 1995.  This increase was primarily due to the
increases in sales of pharmaceutical products by $309,416, Prostate Materials by
$580,619, and oncological products by  $460,710 which the Company began  selling
in June 1993, November 1994, and
 
                                       29

August 1994, respectively. For the years ended December 31, 1995 and 1994, sales
of  Prostate  Materials  to  Stroschein  were  approximately  $1.0  million  and
$470,000, respectively. These sales were  pursuant to an agreement  ('Stroschein
Agreement')  with Stroschein, a German pharmaceutical company, pursuant to which
Bigmar Pharmaceuticals acts as the  exclusive supplier of Prostate Materials  to
Stroschein,  and Stroschein  distributes the  Prostate Materials  in Germany and
other countries. See  'Business -- Products.'  For the year  ended December  31,
1995,  sales of  generic oncological  products consisting  of mercaptopurine and
calcium leucovorin were approximately $670,000. For the period from July 1, 1995
through December 31, 1995 Bioren sales were $3,541,990.
 
     Cost of  Goods  Sold.  Cost  of  goods  sold  increased  by  $3,390,851  to
$4,001,891  for the year ended December 31, 1995 as compared to $611,040 for the
year ended December 31, 1994. This increase was primarily due to the increase in
sales.
 
     Gross Profit. Gross profit  increased by $1,501,884  to $1,598,471 for  the
year  ended December 31, 1995 as compared to $96,587 for the year ended December
31, 1994. Gross profit on Bigmar Pharmaceuticals sales was $439,535 for the year
ended December 31, 1995 as compared to  $96,587 for the year ended December  31,
1994.  The  increase of  $342,948 was  due primarily  to increased  sales. Gross
profit as  a percentage  of net  sales increased  to 28.5%  for the  year  ended
December  31, 1995 as  compared to 13.6%  for the year  ended December 31, 1994.
Without Bioren sales, gross profit as a  percentage of sales in 1995 would  have
been  21.3%, an increase of  7.7%, as compared to  13.6% for 1994. This increase
was due  primarily to  the introduction  of  a new  dosage form  of  lyophilized
calcium leucovorin in April 1995 which yielded a higher margin.
 
     Gross  profit on Bioren sales for the  period from July 1, 1995 to December
31, 1995 was $1,158,936  or 32.7% of such  sales. Bioren gross profit  decreased
from  42.2% of net sales for the six months prior to the Bioren Acquisition as a
result of a shutdown of  the Bioren Facility for  a four-week period during  the
latter  half of 1995 for the installation of a new tank in order to increase the
capacity of the Bioren Facility's water system.
 
     Research and Development Expenses.  Research and development expenses  were
$23,144  for the year ended December 31, 1995 with no such expenses for the year
ended December  31, 1994.  The research  costs were  incurred by  Bioren in  the
second  half of 1995 for  the registration of new  IV Solutions. Pursuant to its
business strategy, the Company intends  to expand its business by  manufacturing
and  marketing certain oncological and biotechnological products and expects its
research and development expenses to be significant in future years.
 
     Selling,  General  and  Administrative   Expenses.  Selling,  general   and
administrative  expenses  increased by  $1,473,786 to  $1,493,055 (26.7%  of net
sales) for the year ended December 31, 1995 as compared to $16,269 (2.3% of  net
sales)  for the year ended December 31,  1994. The increase was primarily due to
the addition of Bioren expenses  of $1,091,074 since July  1, 1995 (the date  of
the  Bioren Acquisition). Bioren  expenses include consulting  fees of $332,055,
promotional expenses of $223,845, employee benefits and other personnel costs of
$170,631, shipping costs of $92,084 and other administrative costs of  $272,459.
Without  the Bioren expenses, selling,  general and administrative expenses were
$401,981 for  the year  ended December  31, 1995.  The increase  of $385,712  as
compared  to selling, general and administrative expenses of $16,269 in 1994 was
due to greater marketing costs and expenses associated with efforts to  increase
sales.
 
     Interest Expense. Interest expense was $182,476 for the year ended December
31,  1995 as compared to  no interest expense in  1994. The interest expense was
primarily due to interest on indebtedness incurred in connection with the Bioren
Acquisition and  interest on  borrowings owed  by Bioren  to its  former  owner,
Galenica.  In addition, the  Company capitalized interest  costs of $235,000 and
$40,000 for  the years  ended  December 31,  1995  and 1994,  respectively.  The
capitalized  interest was incurred in connection with borrowings used to finance
the construction and equipment  of the Bigmar Facility.  See ' -- Liquidity  and
Capital Resources.'
 
     Income Taxes. The tax charge in Switzerland is an accumulation of the taxes
due  to the city, the canton (state) and the federal authorities. Therefore, the
tax burden varies from one entity to another depending upon its location.  While
the actual tax rate is a function of the percentage of profitability in relation
to  taxable equity, the Company believes that 20% is a fair approximation of the
effective cumulative  rate.  In  addition,  as Swiss  tax  laws  do  not  permit
consolidated tax filings, possible tax losses
 
                                       30

<PAGE>
in  one entity do not offset taxable income in another. Tax expense for the year
ended December 31, 1995 was  not significant due to the  amount of the loss  and
the  provision of a full  valuation allowance on the  deferred tax asset arising
from the benefit  of the Company's  operating losses. Tax  expense for the  year
ended December 31, 1994 was $10,553.
 
     Net  Loss. The Company sustained  a net loss of  $97,204 for the year ended
December 31,  1995 as  compared to  net income  of $78,658  for the  year  ended
December  31, 1994.  Such loss  was primarily due  to higher  interest and other
expenses of Bioren.

BIGMAR PHARMACEUTICALS
 
     Net Sales. Net sales increased by  $443,550 to $707,627 for the year  ended

The increase was due to sales of approximately $205,000 of calcium leucovorin in
Germany beginning in August 1994,  increased sales of approximately $442,000  of
Prostate  Materials,  a reduction  of  approximately $224,000  in  other medical
product sales and approximately $21,000 due to a change in the average  exchange
rate between the Swiss franc and the U.S. dollar.
 
     Cost  of Goods Sold. Cost  of goods sold increased  by $428,965 to $611,040
(86% of net sales) for the year ended December 31, 1994 as compared to  $182,075
(69% of net sales) for the year ended December 31, 1993. The increase was due to
increased  sales of Prostate  Materials which have  a higher cost  of goods sold
than the Company's other products.
 
     Gross Profit. Gross  profit increased by  $14,585 to $96,587  for the  year
ended  December 31, 1994 as compared to  $82,002 for the year ended December 31,
1993. Gross profit as a  percentage of net sales decreased  to 14% for the  year
ended December 31, 1994 as compared to 31% for the year ended December 31, 1993.
This  decrease was due  to changes in  the Company's product  mix, including the
introduction of oncological products  in August 1994  and Prostate Materials  in
November  1994, which have a higher cost  of goods sold than the Company's other
products.
 
     Research and Development  Expenses. The  Company incurred  no research  and
development expenses in either of the years ended December 31, 1994 and 1993.
 
     Selling,   General  and  Administrative   Expenses.  Selling,  general  and
administrative expenses  decreased by  $34,541  to $16,269  for the  year  ended
December  31, 1994 as compared to $50,810  for the year ended December 31, 1993.
The decrease  was  primarily  due  to lower  selling  expenses,  related  travel
expenses and lower levels of legal services required by the Company.
 
     Income Taxes. The Company's income taxes increased by $2,257 to $10,553 for
the  year  ended December  31, 1994  as compared  to $8,296  for the  year ended
December 31, 1993.
 
     Net Income. Net income for the year ended December 31, 1994 was $78,658  as
compared  to $23,283 for the year ended  December 31, 1993. The increase was due
primarily to increased sales and  decreased selling, general and  administrative
expenses.
 
BIOREN SA (PREDECESSOR COMPANY)
 
     Net  Sales. Net  sales increased by  $1,775,764 to $5,879,685  for the year
ended December 31, 1994  as compared to $4,103,921  for the year ended  December
31,  1993.  The increase  in  sales was  attributable  to sales  of  $914,000 in
antibiotics, $410,000 in IV  Solution products and $452,000  due to a change  in
the average exchange rate between the Swiss franc and the U.S. dollar.
 
     Cost  of Goods Sold. Cost of goods sold increased by $920,893 to $4,479,243
(76% of  net  sales)  for the  year  ended  December 31,  1994  as  compared  to
$3,558,350  (87%  of net  sales)  for the  year  ended 1993.  This  increase was
primarily due to an increase in sales.
 
     Gross Profit. Gross profit increased by $854,871 to $1,400,442 for the year
ended December 31, 1994 as compared to $545,571 for the year ended December  31,
1993.  Gross profit as a percentage of sales increased to 24% for the year ended
December 31, 1994  as compared to  13% for  the comparable period  in 1993.  The
increase  in the  gross profit  percentage was  the result  of higher  sales, an
increase in sales of  higher margin infusion products  and a more favorable  mix
within the antibiotics product line.
 
     Research  and  Development  Expenses.  Research  and  development  expenses
decreased by $20,561 to $40,736 for the year ended December 31, 1994 as compared
to $61,297 for the year ended December 31,
 
                                       31
 <PAGE>
<PAGE>
1993. The decrease  was primarily  due to  the reduction  in antibiotic  product
registrations  resulting  from management's  decision  to re-focus  the business
toward infusion products sales.
 
     Selling,  General  and  Administrative   Expenses.  Selling,  general   and
administrative  expenses increased by $285,289 to  $1,858,192 for the year ended
December 31, 1994  as compared  to $1,572,903 for  the year  ended December  31,
1993.  The increase was primarily due to higher salary and personnel expenses in
support of the increase in sales.
 
     Loss on Abandonment of Building Improvements and Machinery. Bioren incurred
a loss on the abandonment of  building improvements and machinery for the  years
ended December 31, 1994 and 1993 of $2,295,850 and $830,912, respectively. These
losses  reflect the  reduction in  net value  of certain  equipment and building
improvements due to excess capacity and a change in product strategy.
 
     Other Income (net). Other income decreased  by $189,127 to $94,178 for  the
year ended December 31, 1994 as compared to $283,305 for the year ended December
31,  1993. This  decrease was  a result  of a  reduction in  consulting fees for
accounting and technical services provided to a subsidiary of Galenica.
 
     Interest Expense. Interest  expense increased by  $116,288 to $284,244  for
the  year ended  December 31, 1994  as compared  to $167,956 for  the year ended
December 31, 1993. This increase was primarily due to an increase in  borrowings
for the year ended December 31, 1994.
 
     Extraordinary  Income.  Extraordinary  income  of  $1,468,429  was recorded
during the year  ended December 31,  1994 reflecting the  forgiveness of a  bank
loan.
 
     Net  Loss. Net loss was $1,515,973 for  the year ended December 31, 1994 as
compared to a net loss of $1,804,192  for the year ended December 31, 1993.  The
decrease in the net loss for the year ended December 31, 1994 as compared to the
prior  year was the result of higher  gross profit and the bank loan forgiveness
partially offset by a  larger loss on abandonment  of building improvements  and
machinery.
 
LIQUIDITY AND CAPITAL RESOURCES
 
   
     As  of March 31, 1996 and December 31,  1995, the Company had cash and cash
equivalents of $1,257,555  and $1,425,603, respectively.  The Company's  working
capital  approximated $(137,433) and  $1,204,461 at March  31, 1996 and December
31, 1995, respectively.
    
 
     In March  1996, Protyde  Therapeutics paid  $750,000 to  the Company.  This
payment  is part of  its required capital contributions  to the Partnership. See
'Business -- Collaborative Agreements.'
 
     Trade accounts payable  to third  parties were $2,673,835  and $826,532  at
March  31, 1996 and December 31, 1995,  respectively. The increase is due mainly
to liabilities incurred from construction at the Bigmar Facility of  $1,297,924.
These  liabilities are expected  to become due  in the second  half of 1996. The
Company intends to pay  $1,071,821 of these liabilities  with proceeds from  its
current credit lines.
 
   
     At  March  31,  1996,  the  Company  had  an  aggregate  of  $12,686,626 in
outstanding  indebtedness,   including   $1,847,184  which   is   payable   upon
consummation of the Offering and including the $1,071,821 of accounts payable to
equipment vendors.
    
 
     Through March 31, 1996, the Company had borrowed an aggregate of $1,794,312
from  a  company owned  by certain  stockholders  of the  Company. This  loan is
payable in installments of approximately $179,432  per annum from June 30,  1997
through December 31, 2006 and bears interest at a rate of 9% per annum.
 
   
     Through  June 30, 1995 (the date of the Bioren Acquisition), the operations
of Bioren were financed with loans from  Galenica and Sigal. At March 31,  1996,
outstanding  loans due to Galenica were $1,679,261 and $1,847,184, respectively.
The $1,679,261 loan  is due in  installments of principal  of $419,815 in  1997,
$419,815  in 1998 and $839,631 in 1999. The $1,847,184 loan will be paid in full
upon consummation of the Offering from a portion of the net proceeds received by
the Company.
    
 
   
     The Company's capital  expenditures for  the three months  ended March  31,
1996  aggregated $1,441,417.  The majority  of these  expenditures were  for the
purchase of manufacturing  equipment at  the Bigmar Facility  and were  financed
with  a bank loan aggregating $1,551,428 at  March 31, 1996 which bears interest
at the  rate  of up  to  6.5%  per annum  until  December 31,  1997.  This  loan
commitment  has a limit  of $1,847,187 from  which the Company  may draw, and is
collateralized by the building and
    
 
                                       32

machinery at the Bigmar Facility. The principal  of the loan is due on  December
31, 1997 and may be extended by an agreement between the parties.
    
 
   
     The  Company has other  outstanding bank loans  aggregating $1,973,728 used
for the construction of  the Bigmar Facility. These  loans bear interest at  the
rate of up to 6.5% per annum through December 31, 1997 and are collateralized by
the  building and machinery at the Bigmar Facility. The bank loan has a limit of
$2,749,790 from which the Company may draw. The principal amount of the loan  is
due  on  December 31,  1997  and may  be extended  by  an agreement  between the
parties.
    
 
   
     The Company has a  bank mortgage on  the Bioren Facility  in the amount  of
$2,518,892.  This loan bears interest at 5%  per annum through May 16, 1999. The
principal amount of the loan  is due upon demand after  May 17, 1999 and may  be
extended by an agreement between the parties.
    
 
   
     The  Company  has other  outstanding  bank loans  aggregating approximately
$250,000 bearing interest at an adjustable rate of up to 6.5% per annum  through
December  31, 1997. The principal amount of the loan is due on December 31, 1997
and may be extended by an agreement between the parties.
    
 
   
     The foregoing loan arrangements with the bank contain restrictive covenants
and provisions for events of default.
    
 
   
     On  January  8,  1995,  Chemholding  agreed  to  be  a  surety  for  Bigmar
Pharmaceuticals  in  the amount  of $1.4  million for  the foregoing  loans with
respect to  the  Bigmar Facility.  See  'Business --  Facilities'  and  'Certain
Transactions.'
    
 
     Anticipated   capital  expenditures   for  the   next  12   months  include
approximately $1.0 million for  the purchase of equipment  that will be used  to
manufacture  the Company's  generic oncological  products for  which it  will be
seeking approvals from the FDA. See 'Use of Proceeds.'
 
     In May  1995, Bigmar  Pharmaceuticals issued  1,380 shares  of its  capital
stock  to two  principal stockholders of  the Company and  received net proceeds
therefore of approximately $1.2 million. See 'Certain Transactions.'
 
     The results of the Company's operations are affected by changes in exchange
rates between currencies. Changes  in exchange rates  may negatively affect  the
Company's  consolidated net  sales and  gross profit  margins from international
operations. The Company is exposed to the risk that the dollar-value  equivalent
of  anticipated cash flow will  be adversely affected by  the changes in foreign
currency exchange rates. At such time  as the Company determines that this  risk
is  significant, the Company may attempt to manage the risk by utilizing hedging
techniques, although  there  can  be  no assurance  that  the  Company  will  be
successful  in these  activities. See 'Risk  Factors --  Uncertainty of Currency
Fluctuations.'
 
     The Company anticipates that the  net proceeds from the Offering,  together
with  cash  flow from  operations (if  any),  should be  sufficient to  fund the
Company's operations,  including its  proposed expansion,  for approximately  12
months.  However, there can be no  assurance that events affecting the Company's
operations will not result in the Company depleting its funds before that  time.
The Company may be required to raise substantial additional funds to continue to
fund  operating expenses  or its expansion  strategy. There can  be no assurance
that the Company will be able to  obtain such additional financing or that  such
financing,  if available, will be on acceptable terms. See 'Risk Factors -- Need
for Additional Financing,' and 'Use of Proceeds.'
 
     At December 31, 1995, the Company had a net operating loss carryforward for
Swiss federal and canton income tax purposes of approximately $14,122,000  which
can only be used to offset future taxable income, if any, of Bioren. See Note 10
of Notes to the consolidated financial statements of Bigmar, Inc. In the future,
the Company will also be subject to taxes in the United States.
 
     The  Company is a Delaware corporation which owns 100% of the capital stock
of two Swiss corporations. The Swiss Federal Code of Obligation provides that at
least 5% of a  Swiss company's net  income each year must  be appropriated to  a
legal  reserve  until such  time as  this reserve  is equivalent  to 20%  of the
company's paid-in share capital. In addition, 10% of any distribution made by  a
company  in  excess of  a 5%  dividend must  also be  appropriated to  the legal
reserve. The reserve  of up to  50% of the  share capital is  not available  for
distribution  to  stockholders. See  'Risk Factors  -- Restrictions  on Retained
Earnings.'

                                    BUSINESS
 
GENERAL
 
   
     The Company is currently engaged in manufacturing and marketing 14 types of
IV  Solutions  in  Switzerland  and Lichtenstein  and  marketing  in  Germany of
Prostate Materials  and two  generic  oncological products,  mercaptopurine  and
calcium  leucovorin.  Over the  next  24 months,  the  Company's strategy  is to
manufacture, in  its  state-of-the-art  facilities in  Switzerland,  and  market
generic  oncological  drugs.  In addition,  the  Company  is in  the  process of
preparing   to   market   certain    licensed   proprietary   oncological    and
biotechnological products.
    
 
   
     The Company markets IV Solutions through its own sales force to health care
providers  and third-party payors and markets Prostate Materials, mercaptopurine
and calcium leucovorin to pharmaceutical companies. The Company does not  intend
to market its other products directly to the public. For the year ended December
31,  1995, on a pro forma basis after giving effect to the Bioren Acquisition as
if the transaction had occurred  on January 1, 1995,  the Company's sales of  IV
Solutions  and  antibiotics were  approximately $6.5  million, sales  of medical
products, including  Prostate Materials,  were approximately  $1.4 million,  and
sales of generic oncological products were approximately $670,000. For the three
months  ended March 31,  1996, sales of  these products aggregated approximately
$1.4 million, $319,000 and $210,000, respectively.
    
 
     In 1995, the Company obtained distribution rights to, among other products,
sodium leucovorin and five  generic oncological products including  methotrexate
and  calcium leucovorin,  from Sapec,  and approximately  20 generic oncological
products, including mercaptopurine,  calcium leucovorin  and methotrexate,  from
Cernelle.  Sodium  leucovorin  is  designed to  alleviate  certain  side effects
associated with  chemotherapy more  effectively than  its currently  distributed
counterpart, calcium leucovorin.
 
     The  Company has received approval for  the marketing in Switzerland of two
generic oncological products, doxorubicin and methotrexate, and expects to begin
marketing these products during the second half of 1996. The Company anticipates
that all regulatory approvals for the sale of sodium leucovorin in Germany  will
be  obtained  during the  second half  of 1996  and that  the marketing  of this
product will begin shortly thereafter. There can be no assurance, however,  that
such  regulatory approvals will  be obtained during these  time periods, or that
such approvals will ever be obtained. In addition, the Company has also obtained
the rights  to use,  manufacture and  market, among  other products,  a form  of
recombinant    urokinase   from   Bioferment.   Recombinant   urokinase   is   a
biotechnological product used in the treatment of cardiovascular disease.
 
     The Company  has entered  into exclusive  arrangements with  the  following
non-affiliated  pharmaceutical  companies  to  market  certain  proprietary  and
generic oncological or  biotechnological products, manufactured  or licensed  by
the  Company, in various  territories: Medac in Germany  and the United Kingdom;
Boehringer in  Italy;  Laevosan  in  Switzerland; Vita  in  Spain;  and  Protyde
worldwide,  except  for  certain major  European  countries.  Medac, Boehringer,
Laevosan and  Vita  are  established  pharmaceutical  companies.  Protyde  is  a
development stage company.
 
BUSINESS STRATEGY
 
GENERAL
 
     The Company's business strategy over the next 24 months is to:
 
           manufacture and market approximately seven injectable and lyophilized
           oncological products, including sodium leucovorin;
 
           manufacture and market additional oncological products as the patents
           relating to the products expire;
 
           increase  the number  of pharmaceutical  companies in  Europe through
           which  the  Company's  oncological  products  are  marketed  and  the
           territories in which they are distributed;
 
           market recombinant urokinase; and
 
           expand  the  marketing of  IV  Solutions in  Switzerland  through the
           Company's own sales force.

PRODUCTS
 
IV SOLUTIONS
 
   
     The Company manufactures, at its Bioren Facility, and markets 14  different
IV Solutions. The Company's IV Solutions generally consist of different chemical
entities,  such  as  sodium  chloride,  electrolytes,  carbohydrates  and  other
nutrients, which  are  intravenously  administered to  a  patient.  The  Company
markets  IV  Solutions,  through its  own  sales force,  to  hospitals, clinics,
retirement  homes,  nursing  homes,  managed  health  care  organizations,  home
infusion   providers  and  other  health   care  providers  in  Switzerland  and
Lichtenstein. For the year ended December 31,  1995, on a pro forma basis  after
giving  effect to  the Bioren  Acquisition and  the Exchange  as if  each of the
transactions had  occurred  on  January  1, 1995,  the  Company's  sales  of  IV
Solutions  were approximately $5.5 million. For the three months ended March 31,
1996, sales of IV  Solutions approximated $1.4 million.  The Company intends  to
continue  manufacturing and marketing  IV Solutions and  is seeking to penetrate
additional markets in Switzerland. See ' -- Marketing and Sales.'
    
 
     In March 1995, Bioren and PLM  entered into the PLM Agreement which  grants
Bioren the exclusive right to distribute its IV Solutions throughout Switzerland
and  Lichtenstein in PLM's collapsable containers.  The PLM Agreement expires in
the year 2005,  unless it  is earlier  terminated. Under  the terms  of the  PLM
Agreement,  PLM is  entitled to terminate  the exclusive right  contained in the
agreement if, among other things, Bioren  does not purchase a minimum number  of
intravenous solution containers each year. In addition, the PLM Agreement may be
terminated by either party, upon the occurrence of certain specified conditions,
including  if  the  products  or  the production  infringe,  or  are  alleged to
infringe,  upon  any  intellectual  property  right  of  any  third  party.  The
termination  of the PLM  Agreement would have  a material adverse  effect on the
Company. See 'Risk Factors -- Reliance on PLM.'
 
PROSTATE MATERIALS
 
     The  Company  markets  natural  medications  used  for  the  treatment   of
non-infectious  prostate  enlargement. The  Prostate  Materials are  composed of
natural pollen derived  from plant  extracts. For  the year  ended December  31,
1995, the Company's sales of Prostate Materials to Stroschein were approximately
$1.0  million. For the three months ended March 31, 1996, there were no sales of
Prostrate Materials to Stroschein.
 
     In  October  1994,  Bigmar  Pharmaceuticals  entered  into  the  Stroschein
Agreement  with Stroschein, pursuant to which Bigmar Pharmaceuticals acts as the
exclusive supplier of Cernilton, a Prostate Material, and Stroschein distributes
the Prostate Material in Germany.  The Stroschein Agreement provides for  annual
minimum  quantity requirements in order  to maintain exclusivity. The Stroschein
Agreement expires  in  October  1999  and  will  be  automatically  renewed  for
consecutive  two year  periods, unless terminated  by the parties.  In the event
that Stroschein terminates the agreement as a result of Bigmar  Pharmaceuticals'
breach  or default thereunder, Bigmar Pharmaceuticals is required to transfer to
Stroschein the Cernilton  product registration  and the  necessary know-how  and
authorizations to enable Stroschein to manufacture Cernilton. The termination of
the  Stroschein Agreement would  have a material adverse  effect on the Company.
See 'Risk Factors -- Dependence Upon Significant Customers.'
 
ONCOLOGICAL PRODUCTS
 
     The Company currently markets two generic oncological products in  Germany,
mercaptopurine  and calcium leucovorin. For the year ended December 31, 1995, on
a pro forma  basis, the  Company's sales  of generic  oncological products  were
approximately  $670,000. For the  three months ended March  31, 1996 these sales
aggregated approximately $210,000.
 
     In November  1995, Bigmar  Pharmaceuticals and  Cernelle entered  into  the
Cernelle  Agreement  pursuant  to  which  Bigmar  Pharmaceuticals  obtained  the
exclusive worldwide distribution rights to approximately 20 generic  oncological
products   including   calcium  leucovorin,   methotrexate   and  mercaptopurine
('Cernelle Products') manufactured by Cernelle. The Cernelle Agreement  provides
for  a one time payment  of $100,000 for the grant  of such exclusive rights and
licenses which  is  payable upon  notification  by Cernelle  that  the  Cernelle
Products  are ready for initial shipment to Bigmar Pharmaceuticals. In addition,
Bigmar  Pharmaceuticals  will  be  responsible  for  ongoing  fees  based   upon
 
                                       35
 <PAGE>
<PAGE>
the  size of its orders for Cernelle  Products. The initial term of the Cernelle
Agreement is 15 years, commencing  on the date of  the first commercial sale  by
Bigmar  Pharmaceuticals  of  the  Cernelle  Products.  Upon  termination  of the
Cernelle Agreement, Bigmar Pharmaceuticals will retain a non-exclusive worldwide
right to distribute the Cernelle Products for three additional years, at  prices
and  on terms no  less favorable to  Bigmar Pharmaceuticals than  the prices and
terms extended  by Cernelle  to any  other  person or  entity for  the  Cernelle
Products.  Either party may terminate the Cernelle Agreement upon the occurrence
of certain specified conditions. The termination of the Cernelle Agreement would
have a material adverse effect on the Company. See 'Risk Factors -- Reliance  on
Collaborative Arrangements; Management Affiliations with Collaborators.'
 
     In  November  1995, Bigmar  Pharmaceuticals  and Cernelle  entered  into an
exclusive technical  services  agreement  ('Cernelle TSA'),  pursuant  to  which
Cernelle  will prepare abbreviated new drug application ('ANDA') submissions for
Bigmar Pharmaceuticals to submit to the FDA or other appropriate authority  with
jurisdiction  over the  Cernelle Products. Generally,  Bigmar Pharmaceuticals is
obligated to  pay Cernelle  a fee  of $20,000  for each  ANDA submitted  to  and
accepted  by Bigmar Pharmaceuticals with respect to a Cernelle Product. Cernelle
will assign to Bigmar  Pharmaceuticals the sole and  exclusive right, title  and
interest  in and to each ANDA.  The term of the Cernelle  TSA is 15 years and is
renewable upon the  mutual written agreement  of the parties.  Either party  may
terminate  the Cernelle TSA upon the occurrence of certain specified conditions.
The termination of the Cernelle TSA would have a material adverse effect on  the
Company. See 'Risk Factors -- Reliance on Collaborative Arrangements; Management
Affiliations with Collaborators.'
 
PROPOSED PRODUCTS
 
GENERIC ONCOLOGICAL PRODUCTS
 
     The  Company has  identified approximately  30 oncological  drugs which are
currently generic and 15 additional oncological drugs that the Company  believes
will  become  generic by  the  year 2000.  Generic  drugs are  the  chemical and
therapeutic equivalents  of brand  name (proprietary)  drugs and  generally  are
marketed once the patent on the proprietary drug has expired.
 
     The following table lists the generic oncological products that the Company
intends  to manufacture  and market  to pharmaceutical  companies for  resale in
Switzerland, Germany  and the  United States  over the  next 24  months and  the
estimated time periods for each product.

* Introduced.
 
     The  Company believes  that it  will be  able to  obtain approval  of these
products in Germany, as indicated above, because it intends to purchase approved
marketing applications  from  Medac and  transfer  the manufacturing  site  from
Germany  to the  Bigmar Facility. Although  this transfer  of manufacturing site
requires the approval  of the  German regulatory  authority, the  time for  such
approval  is much faster than the three to five year time period for approval of
full marketing applications in Germany.
 
     Over the next 24  months the Company's strategy  is to manufacture, in  its
state-of-the-art  facilities, in  Switzerland and  market additional oncological
products as their patents expire.
 
     There can be no assurance that  the Company will manufacture or market  any
of  the foregoing  products during  the time  periods indicated  if at  all. The
commercialization  of  these  products  will  depend  on  a  number  of  factors
including,  but not limited to, the successful results of the Company's clinical
toxicity  studies  and  obtaining  regulatory  approval.  Although  the  Company
believes  that each of these proposed products has commercial value, the Company
may choose not to manufacture or market some
 
                                       36

or all  of these  products. See  'Risk  Factors --  No Assurance  of  Successful
Product  Development;  Uncertainty  of  Market  Acceptance  of  Certain Proposed
Products and  -- FDA, International and Other Governmental Regulations.'
 
SODIUM LEUCOVORIN AND OTHER PROPOSED PRODUCTS
 
     Sodium  leucovorin  is  designed  to  alleviate  certain  side  effects  of
chemotherapy  more  effectively  than  its  currently  distributed  counterpart,
calcium leucovorin. For many years, the calcium salt of leucovorin has been used
as a major adjuvant drug in  oncology. Specifically, calcium leucovorin is  used
in  rescue therapy for purposes of reducing toxicity in methotrexate treatments.
When combined  with high-dosage  calcium  leucovorin, high  dosage  methotrexate
therapy has shown strong clinical results.
 
     Some  oncologists  have identified  a need  for the  development of  a more
soluble form of leucovorin to reduce the overall volume of solution injected  as
well as to reduce the amount of salts administered that are not directly related
to  the active drug substance. In response to  this need, a more soluble form of
leucovorin, sodium leucovorin, has been developed by Sapec. Sodium leucovorin is
more than five times as soluble as calcium leucovorin, allowing solutions to  be
prepared  containing  sodium leucovorin  at 5%  (50  mg/ml) in  isotonic saline.
Solutions of  sodium leucovorin  at 50  mg/ml are  isotonic and  do not  require
supplementation  with additional salts.  As a result,  sodium leucovorin reduces
the overall  volume  of  solution  injected and  reduces  the  amount  of  salts
administered  which  are not  directly  related to  the  active drug.  See 'Risk
Factors -- No Assurance of Successful Product Development; Uncertainty of Market
Acceptance of Certain Proposed Products.'
 
     In February 1994, Sapec filed a patent application in Switzerland and  then
extended  the  application  to  the  United  States  and  the  EU  covering  the
composition of matter and  the manufacturing process  for sodium leucovorin.  An
application  was filed for the sale of calcium leucovorin in Germany in 1993. In
1995, an amendment to this  application was filed to  change the liquid form  of
calcium  leucovorin to  sodium leucovorin. Sodium  leucovorin is  a new chemical
entity which has  never been approved  before in Germany.  The Company  believes
that  the German regulatory authority might  act on its application more quickly
than it does for generic drugs because of its similarity to calcium  leucovorin.
The  Company believes that all regulatory  approvals will be obtained during the
second half  of 1996  and that  marketing  of this  product will  begin  shortly
thereafter.  However,  there can  be no  assurance the  Company will  obtain the
requisite regulatory approvals  by that  time or at  all. See  'Risk Factors  --
Reliance    on   Collaborative   Arrangements;   Managment   Affiliations   with
Collaborators,  -- Uncertain Protection  of Patents and Proprietary Rights,  and
 -- FDA, International and Other Governmental Regulations.'
 
     In  1995, Bioren and Sapec entered  into the Sapec Agreement which provides
that, subject  to restrictions  on  the resale  of  certain Sapec  Products  (as
hereinafter defined) to pharmaceutical companies in selected territories, Bioren
shall  be the exclusive  worldwide distributor of,  among other products, sodium
leucovorin and  five generic  oncological products  developed by  Sapec  ('Sapec
Products').  The Sapec Agreement provides that  Sapec will obtain all regulatory
approval necessary for Bioren, or its  designee, to import, distribute and  sell
any  Sapec  Products throughout  the world.  Bioren  has agreed  to pay  Sapec a
one-time fee of  $100,000 for the  grant of such  exclusive rights and  licenses
which  is payable upon notification  by Sapec that the  Sapec Products are ready
for initial shipment  to Bioren.  The Sapec Agreement  provides for  a one  time
payment of $100,000 for the grant of such exclusive rights and licenses which is
payable upon notification by Sapec that the Sapec Products are ready for initial
shipment  to Bioren.  In addition, Bioren  will be responsible  for ongoing fees
based upon  the size  of its  orders  for Sapec  Products. The  Sapec  Agreement
terminates  15 years from the  date of the first commercial  sale by Bioren of a
Sapec Product. Bioren will  have a non-exclusive  worldwide right to  distribute
the  Sapec  Products for  three  additional years  after  the expiration  of the
initial term or any renewal term, as the case may be, at prices and on terms, no
less favorable to  Bioren than the  prices and  terms extended by  Sapec to  any
other  person or entity. Either party may terminate the Sapec Agreement upon the
occurrence of  certain  specified  conditions.  The  termination  of  the  Sapec
Agreement  would  have  a material  adverse  effect  on the  Company.  See 'Risk
Factors -- Reliance on Collaborative Arrangements; Management Affiliations  with
Collaborators.'

BIOTECHNOLOGICAL PRODUCTS
 
     In  November 1995, Bigmar  Pharmaceuticals and Bioferment  entered into the
Bioferment Agreement pursuant to which Bioferment granted Bigmar Pharmaceuticals
the exclusive  worldwide  rights  to use,  manufacture  and  market  recombinant
urokinase,  a recombinant form of human growth hormone and a recombinant form of
interferon as well as other pharmaceutical products that Bioferment may  develop
as  may be  agreed upon by  Bioferment and  Bigmar Pharmaceuticals (collectively
'Bioferment Products'). Bioferment either owns the intellectual property  rights
with respect to the Bioferment Products or has the exclusive rights to make, use
and sell the Bioferment Products.
 
     The  Bioferment  Agreement provides  that  all regulatory  applications for
approval to import, register and market, the Bioferment Products shall be  filed
in  the name of, and owned  by, Bigmar Pharmaceuticals. The Bioferment Agreement
will terminate 15 years after the  first commercial sale of the last  Bioferment
Product  introduced by  Bigmar Pharmaceuticals, its  affiliates or sublicensees.
The Bioferment Agreement may be terminated  by either party upon the  occurrence
of  certain specified  conditions. The  termination of  the Bioferment Agreement
would  have   a   material   adverse   effect  on   the   Company.   See   'Risk
Factors  -- Reliance on Collaborative Arrangements; Management Affiliations with
Collaborators.'
 
     Pursuant to the Bioferment Agreement, Bigmar Pharmaceuticals agreed to  pay
Bioferment  (i) $100,000 on  March 1, 1996  (which has been  extended to July 1,
1996),  (ii)   $100,000  promptly   following  the   first  filing   by   Bigmar
Pharmaceuticals  with the FDA of an investigational new drug application ('IND')
relating to a Bioferment  Product, (iii) $100,000  promptly following the  first
filing  with the FDA of a New Drug Application ('NDA') for a Bioferment Product,
and (iv) $100,000  promptly following  the approval  by the  FDA of  the NDA  or
Product  License  Application  ('PLA')  for each  Bioferment  Product  for which
approval is sought  by Bigmar Pharmaceuticals  (payment not to  be required  for
more  than two products). The license fee aggregating $500,000 shall be credited
against the royalty  obligations due to  Bioferment from Bigmar  Pharmaceuticals
pursuant  to the Bioferment Agreement. Commencing with the first commercial sale
of a Bioferment  Product by Bigmar  Pharmaceuticals, Bigmar Pharmaceuticals  has
agreed  to pay Bioferment, on a quarterly basis, a royalty equal to a percentage
of the Company's net  sales of these  products. The license  fee due under  this
agreement,  will be  paid from  the net  proceeds of  the Offering.  See 'Use of
Proceeds.'
 
     During the first  three years  of the Bioferment  Agreement, if  Bioferment
materially  breaches any material provision relating to purchase and supply, and
such breach shall fail to be cured within 60 days after written notice is  given
by  Bigmar  Pharmaceuticals,  or  in  the event  that  Bioferment  is  unable to
adequately provide Bigmar Pharmaceuticals with a stable and reliable source  for
Bioferment   Products,   Bigmar   Pharmaceuticals  shall   have   an  exclusive,
transferrable, sublicensable license to manufacture the Bioferment Products  for
the  use of  Bigmar Pharmaceuticals  and Bigmar  Pharmaceuticals' affiliates and
sublicensees in Bigmar Pharmaceuticals' field of use.
 
  Recombinant Urokinase
 
     Recombinant urokinase is a biotechnological  product used in the  treatment
of  cardiovascular disease. Recombinant  urokinase is designed  to eliminate the
risk of  viral  contamination  that  exists  with  natural  urokinase  products.
Bioferment  uses a  culture media  in the  manufacturing process  of recombinant
urokinase. In 1993, a  patent application was filed  by Dr. Ferruccio Messi  for
this   culture  media  in  major   European  countries.  Bioferment  and  Bigmar
Pharmaceuticals have  been granted  non-exclusive licenses  to use  the  culture
media. The Company believes that recombinant urokinase is in the final stages of
development.  The Company does not  intend to manufacture recombinant urokinase.
The Company is collaborating  with Medac to initiate  the regulatory filings  in
Germany,  including limited  toxicology studies  and human  clinical trials. The
Company anticipates  that  regulatory  approvals for  the  sale  of  recombinant
urokinase  in Germany will be  obtained during the second  half of 1997 and that
the marketing  for  this product  will  begin shortly  thereafter.  The  Company
believes  that marketing clearance from the  German regulatory authority will be
obtained in  the second  half  of 1997,  as opposed  to  from the  EMEA  because
recombinant  urokinase does  not pose a  risk of viral  contamination, and would
replace the  naturally derived  urokinase that  is currently  on the  market  in
Germany. However, there can
 
                                       38

be no assurance that the requisite regulatory approvals will be obtained by that
time  or at  all. See 'Risk  Factors -- Reliance  on Collaborative Arrangements;
Management Affiliations  with Collaborators,   --  Manufacturing Facilities  for
Proposed  Products,  -- Uncertain Protection  of Patents and Proprietary Rights,
and  -- FDA, International and Other Governmental Regulations.'
 
OTHER PROPOSED PRODUCTS
 
  Recombinant Human Growth Hormone and Recombinant Interferon
 
     In  November  1995,  Bigmar  Pharmaceuticals  acquired  the  licenses  from
Bioferment  to use,  manufacture and market  a form of  recombinant human growth
hormone, a biotechnological product which  is used in connection with  assisting
children  in  the  growth  process  and  a  form  of  recombinant  interferon, a
biotechnological product which may be used  for and in the treatment of  cancer.
Recombinant  human growth  hormone and recombinant  interferon are  in the early
stages of development. No  assurance can be given  that these proposed  products
will  ever be developed. See 'Risk Factors -- No Assurance of Successful Product
Development; Uncertainty of Market Acceptance of Certain Proposed Products.'
 
  Virosome and Liposome Technologies
 
     In December 1995,  Bigmar Pharmaceuticals  and Bioferment  entered into  an
agreement  ('Bioferment  Distribution  Agreement') for  the  exclusive worldwide
distribution by Bigmar Pharmaceuticals  of existing Bioferment products  derived
from   Bioferment's  other  technologies  such  as  the  virosome  and  liposome
technologies and any  additional products  developed by  Bioferment using  these
technologies  for the term of the Bioferment Distribution Agreement. Pursuant to
the Bioferment Distribution Agreement, Bigmar  Pharmaceuticals has the right  of
first  refusal for any products derived  from these technologies. The Bioferment
Distribution Agreement provides for  one-time payment by Bigmar  Pharmaceuticals
of $100,000 for the grant of such exclusive rights and licenses which is payable
upon  notification  by Bioferment  that the  Bioferment  Products are  ready for
initial shipment to Bigmar Pharmaceuticals. In addition, Bigmar  Pharmaceuticals
is  responsible for  ongoing fees  based upon  the size  of its  orders for such
Bioferment products, which are payable  pursuant to the Bioferment  Distribution
Agreement.  The Bioferment Distribution  Agreement will terminate  15 years from
the date of  the first commercial  sale by Bigmar  Pharmaceuticals of a  product
covered  by the Bioferment  Distribution Agreement and  is renewable upon mutual
agreement of  the  parties. Bigmar  Pharmaceuticals  will have  a  non-exclusive
worldwide   right  to  distribute   the  products  covered   by  the  Bioferment
Distribution Agreement for three  additional years after  the expiration of  the
initial  term or any renewal term. No assurance can be given that these proposed
technologies or proposed products will ever be developed.
 
COLLABORATIVE AGREEMENTS
 
     The Company  has entered  into exclusive  arrangements with  the  following
non-affiliated  companies to market certain  proprietary and generic oncological
products,  proposed   oncological   products   or   biotechnological   products,
manufactured  or licensed by  the Company, in  various territories. Restrictions
regarding exclusivity and right of first refusal limit the Company's ability  to
pursue  and negotiate  collaborative arrangements  with other  entities on terms
which may be more  favorable to the  Company. See 'Risk  Factors -- Reliance  on
Network  of  Pharmaceutical Companies  for  Marketing; Dependence  on Additional
Collaborative Arrangements.'
 
  Medac
 
     In September 1995, Bigmar Pharmaceuticals  and Medac entered into a  series
of  international distribution  agreements (the 'Medac  Agreements') relating to
certain oncological products such as mercaptopurine and doxorubicin. Pursuant to
these agreements,  Bigmar Pharmaceuticals  and Medac  have divided,  subject  to
future  adjustment, the exclusive right to sell the oncological products covered
by the agreements in  various countries in Europe,  South America, Asia and  the
United  States. Pursuant to  the Medac Agreements,  the Company anticipates that
Medac will market  certain of  the Company's oncological  products and  proposed
products in Germany and the United Kingdom.

  Boehringer
 
   
     In  December 1995,  Bigmar Pharmaceuticals  and Boehringer  entered into an
agreement ('Boehringer Agreement') for the exclusive distribution by  Boehringer
of  certain  oncological  products such  as  methotrexate,  doxorubicin, calcium
leucovorin and mercaptopurine ('Boehringer Products') in Italy, Vatican City and
the San Marino  Republic ('Boehringer  Territory'). Pursuant  to the  Boehringer
Agreement,  the Company will supply Boehringer with the products on an exclusive
basis and has  granted Boehringer an  option to distribute  new products in  the
Boehringer  Territory. Under the terms of  the Boehringer Agreement, the Company
will receive a flat payment from Boehringer for each product distributed in  the
Boehringer  Territory. The Boehringer Agreement terminates in December 2005, but
is subject to  automatic one year  extensions unless earlier  terminated by  the
parties. Either party may terminate the Boehringer Agreement upon the occurrence
of certain specified conditions.
    
 
  Laevosan
 
     In  December  1995, Bigmar  Pharmaceuticals  and Laevosan  entered  into an
exclusive distribution agreement ('Laevosan Agreement') pursuant to which Bigmar
Pharmaceuticals will supply certain oncological products such as doxorubicin and
methotrexate to Laevosan for sale in Switzerland. Under the Laevosan  Agreement,
Laevosan is required to sell minimum quantities each year and, if Laevosan fails
to  sell such amounts, Bigmar Pharmaceuticals can convert the Laevosan Agreement
to a non-exclusive distribution  arrangement. The Laevosan Agreement  terminates
on  December,  1998, but  is subject  to automatic  one year  extensions, unless
earlier terminated  by the  parties.  Either party  may terminate  the  Laevosan
Agreement upon the occurrence of certain specified conditions.
 
  Vita
 
     In  July 1995, Bigmar Pharmaceuticals and  Vita entered into a distribution
agreement ('Vita Agreement') pursuant to which Vita will buy certain oncological
products exclusively  from Bigmar  Pharmaceuticals and  will commercialize  such
products  in Spain. In the  event Vita ceases to  commercialize any product, the
marketing  authorization  for  that  product  will  be  transferred  to   Bigmar
Pharmaceuticals  at a  nominal fee. The  Vita Agreement  terminates in September
2005 but may be extended automatically for an additional one year period. Either
party may terminate the Vita Agreement upon the occurrence of certain  specified
conditions.
 
  Protyde
 
     In   October  1995,   Bigmar  Therapeutics  and   Protyde  Therapeutics,  a
wholly-owned subisidiary of  Protyde, a  development stage  company, formed  the
Partnership,   for   the  purpose   of   manufacturing  and   marketing  certain
pharmaceutical  products   ('Partnership  Products').   The  business   of   the
Partnership is to obtain FDA approval to market the Partnership Products, and to
commence  the manufacturing and  marketing of the  Partnership Products. Each of
the partners initially  has a 50%  interest in the  Partnership and neither  may
sell,  assign,  pledge or  otherwise transfer  any  portion of  their respective
interests, except to affiliates  of the Company and  Protyde, without the  other
partner's prior consent. As its initial capital contribution to the Partnership,
Protyde  Therapeutics will  contribute to  the Partnership  up to  $3,075,000 in
cash, the first $750,000  of which was  paid to the Company  on March 29,  1996,
with  the balance to be contributed  at such times and in  such amounts so as to
enable the  Partnership to  timely  satisfy its  obligations,  and to  make  its
payments under the terms of its manufacturing agreement. As Bigmar Therapeutics'
capital  contribution  to the  Partnership, Bigmar  Therapeutics will  cause the
Company to make its  manufacturing capacity available  to the Partnership  under
the  terms  of  the  Manufacturing  Agreement  (as  defined  below).  Under  the
Partnership Agreement, the Partnership is the sole owner of all right, title and
interest  in  all  FDA-approved  ANDAs  for  the  Partnership  Products.  Unless
terminated  by either party upon the occurrence of certain specified conditions,
the Partnership will continue until December 31, 2005.
 
     In October  1995, the  Partnership and  Protyde entered  into a  sales  and
marketing  agreement ('Marketing  Agreement') pursuant to  which the Partnership
appointed Protyde, on  an exclusive basis,  to market, sell  and distribute  the
Partnership  Products worldwide, except for certain designated countries, and to
assist the Partnership in certain  pre-manufacturing activities relating to  the
Partnership  Products. Unless terminated by either  party upon the occurrence of
certain specified conditions, the
 
                                       40
 <PAGE>
<PAGE>
Marketing Agreement will remain in effect  until the earlier of the  dissolution
of the Partnership or December 31, 2005.
 
     In   October  1995,  the  Partnership  and   the  Company  entered  into  a
manufacturing  agreement  ('Manufacturing  Agreement')  pursuant  to  which  the
Partnership  engaged the Company to, among  other things (i) acquire and perform
stability testing on all raw materials and packaging materials necessary for the
manufacture of  the  Partnership Products,  (ii)  make its  production  capacity
available  to the Partnership in order to meet production obligations, and (iii)
undertake all measures for quality control which are either required by the  FDA
or  requested by  the Partnership.  The Manufacturing  Agreement sets  forth the
minimum production  capacity  which the  Company  must make  available  to  fill
Partnership  orders and the minimum annual  orders of Partnership Products which
the Partnership must  place. If, with  respect to any  Partnership Product,  the
Partnership  fails  to  satisfy  the  minimum  annual  orders,  the  Company may
terminate the Manufacturing Agreement with respect  to that product on 180  days
prior  notice. Unless terminated by either  party upon the occurrence of certain
specified conditions, the Manufacturing Agreement  shall remain in effect  until
the earlier of the dissolution of the Partnership or December 31, 2005.
 
MANUFACTURING AND SUPPLIERS
 
     The  Company  has  two  facilities,  the  Bioren  Facility  and  the Bigmar
Facility. The  Bioren  Facility  is  a  57,000  square  foot,  state-of-the-art,
facility  in Couvet, Switzerland  where the Company  manufactures and markets IV
Solutions and will develop  and manufacture non-cytotoxic oncological  products.
The  Company intends to dedicate approximately  25,000 square feet of the Bioren
Facility to test  and manufacture  certain oncological products  such as  sodium
leucovorin.  The  Bigmar Facility  is  a 25,000  square  foot, state-of-the-art,
facility,  in  Barbengo,  Switzerland  where   the  Company  will  develop   and
manufacture  cytotoxic oncological products. There can  be no assurance that the
Bigmar Facility  or the  dedicated area  of the  Bioren Facility  will be  fully
operational or that regulatory approvals will be obtained in a timely manner, if
at  all. Further, the  Company intends to  enter into an  agreement with another
party pursuant to  which such  company will  manufacture recombinant  urokinase,
which  the Company will  market. The amount  of resources and  the time that the
other party will devote towards producing the products on behalf of the  Company
and  the manufacturing  procedures and  quality control  will not  be within the
Company's control. See  'Risk Factors --  Manufacturing Facilities for  Proposed
Products.'
 
     The   Company's  manufacturing  facilities  will  be  subject  to  periodic
inspections by the FDA and other United States federal agencies and the FDA  may
choose  to  inspect  the  Company's facilities  before  approving  the Company's
products for sale in  the United States. The  Company's facilities have not  yet
been  inspected  by  the  FDA, however,  the  Company  has  retained independent
consultants  to  assist  in  this  process  of  ensuring  compliance  with   GMP
requirements.  The IKS will also inspect the manufacturing facility to determine
if the  manufacturer  is  complying with  good  manufacturing  practices  before
approval is granted to produce the drug product.
 
     Quality   monitoring  and   testing  programs  and   procedures  have  been
established by the  Company to  assure that all  critical activities  associated
with  the production, control and distribution of its products will be carefully
controlled and evaluated. The Company's strategy is to seek to meet the  highest
quality  standards, with the goal  of assuring the purity  and safety of each of
its products.
 
     The capital costs  associated with equipping  a facility and  manufacturing
oncological  products are substantial and  the manufacturing process is complex.
Further, because some  oncological products  are highly toxic,  the facility  in
which  they  are  manufactured,  the  method  of  manufacture,  as  well  as the
employees' working conditions, are regulated  by the FDA and foreign  regulatory
authorities. As the manufacturing of cytotoxic oncological products is expensive
and  complex,  only  a  few  companies  throughout  the  world  engage  in their
manufacture.
 
     The majority of raw materials needed to manufacture the Company's  products
and  proposed products generally are not readily available and must be purchased
from limited  sources.  In  addition,  the Company  obtains  containers  for  IV
Solutions  from a sole supplier.  The Company's reliance on  a sole or a limited
number  of  suppliers  involves  several  risks  including,  among  others,  the
inability  to obtain an adequate supply of required raw materials and components
in order to manufacture or market a
 
                                       41
 <PAGE>
<PAGE>
product or  proposed product,  increased  raw material  or component  costs  and
reduced  control over pricing, quality and  timely delivery. Any interruption in
the supply of raw materials or  components could have a material adverse  effect
on  the  Company. Furthermore,  obtaining raw  materials from  a new  source may
require additional regulatory approval. In addition, certain potential alternate
suppliers may have pre-existing exclusive relationships with competitors of  the
Company and others which may preclude the Company from being able to manufacture
certain  of its  proposed products.  See 'Risk  Factors --  Reliance on  PLM and
 -- Dependence on Key Suppliers.'
 
RESEARCH AND DEVELOPMENT
 
     To date,  substantially  all  of the  Company's  research  and  development
efforts have been performed by collaborators. Upon consummation of the Offering,
the  Company  intends  to  retain  approximately  15  employees  or consultants,
including chemists, biologists and technical  personnel. The Company expects  to
use  a  portion of  the  proceeds of  the Offering  for  the development  of its
proposed products  and  intends  to  continue the  development  and  testing  of
oncological  products, such as sodium  leucovorin and biotechnological products,
such as recombinant urokinase; purchasing  and formulating raw materials into  a
finished  product, scaling up the development of the product from the laboratory
phase to  the  production  phase;  conducting  clinical  trials  and  conducting
stability  and  bioequivalence  testing of  the  finished product.  See  'Use of
Proceeds.'
 
MARKETING AND SALES
 
     The Company markets IV Solutions through its own sales force to  hospitals,
clinics,  retirement homes,  nursing homes,  managed health  care organizations,
home infusion providers and  other health care  providers, and markets  Prostate
Materials,  mercaptopurine and calcium  leucovorin, to pharmaceutical companies.
The Company does not  intend to market its  other products or proposed  products
directly  to the public. During 1995, the Company granted certain companies such
as Medac, Boehringer,  Laevosan, Vita  and Protyde the  exclusive marketing  and
distribution  rights to certain of the Company's oncological products and future
oncological products in  certain territories.  The amount of  resources and  the
time  that any of these collaborators devote  towards marketing and sales of the
Company's products  and proposed  products are  not within  the control  of  the
Company.  All  of  the  agreements terminate  under  certain  circumstances. The
termination of any of these agreements  would have a material adverse effect  on
the  Company.  See  'Risk  Factors  --  Reliance  on  Network  of Pharmaceutical
Companies for Marketing; Dependence on Additional Collaborative Arrangements.'
 
COMPETITION
 
     The pharmaceutical  and biotechnology  industries  are subject  to  intense
competition  and rapid and significant  technological change. Competitors of the
Company are numerous and include  United States and international companies.  In
the  intravenous infusion market,  the Company faces  competition from Braun and
Fresenius and in  the Prostate  Material market, the  Company faces  competition
from  Allergon,  a division  of Pharmacia  &  Upjohn, Inc.  In addition,  in the
oncological and  biotechnological markets,  the Company  faces competition  from
Bristol-Myers  Squibb Co., Chiron Inc., Pharmachemie, BV and Pharmacia & Upjohn,
Inc. Furthermore, in oncological and biotechnology markets the Company may  face
competition  from alternative methods of  treatment such as, in  the case of its
oncological  products,  surgical  procedures,  radiation  treatments  and  other
treatments.
 
     Many  of the Company's competitors, including all of the companies referred
to above,  have  substantially greater  financial  and technical  resources  and
production  and marketing  capabilities than  the Company.  The Company believes
that the  principal  competitive factors  affecting  its products  and  proposed
products  are timing of  product introduction, price,  quality, and service. The
Company believes that  quality and service  continue to be  an advantage in  the
sale  of IV Solutions  and Prostate Materials. The  Company believes that price,
timing, quality,  customer service  and  breadth of  its  product line  are  all
important competitive factors for its oncological products, proposed oncological
products  and  proposed  biotechnological  products.  The  ability  to introduce
generic versions of products promptly after a proprietary drug's patent  expires
and  the breadth of the product line  may give companies a competitive advantage
over the  Company. See  'Risk  Factors --  Competition and  Rapid  Technological
Change.'

PATENTS AND PROPRIETARY RIGHTS
 
     The  Company  relies on  a  combination of  patent  applications, licenses,
trademarks,  trade  secrets  and   non-disclosure  agreements  to  protect   its
proprietary  technology,  rights and  know-how  and the  technology,  rights and
know-how licensed from  others. In  addition, the  Company is  currently in  the
process  of  implementing  a  policy  that  requires  its  personnel  to execute
non-disclosure  agreements.  There  can  be   no  assurance  that  such   patent
applications  or any resulting patents or any licenses or trademarks will not be
infringed upon, that the Company's trade secrets will not otherwise become known
to or  independently developed  by competitors,  that non-disclosure  agreements
will  not be breached, or that the  Company would have adequate remedies for any
such infringement  or breach.  Litigation may  be necessary  to enforce  patents
issued to the Company, to protect the Company's proprietary rights, or to defend
the  Company against third-party claims of infringement of proprietary rights of
others. Such litigation could  result in substantial cost  to the Company and  a
diversion  of  effort  of the  Company  and its  management.  Patents concerning
pharmaceutical or  biotechnological  products generally  are  highly  uncertain,
involve  complex legal, scientific and factual  questions and have recently been
the subject  of much  litigation.  To date,  no  consistent policy  has  emerged
regarding  the breadth  of claims allowed  or the degree  of protection afforded
under these  patents.  Accordingly,  there  can  be  no  assurance  that  patent
applications  which underlie the Company's licenses will result in patents being
issued,  or  that,  if  issued,  the  patents  will  afford  protection  against
competitors  with similar technology. Because of the extensive time required for
development, testing  and  regulatory  review  of a  potential  product,  it  is
possible   that  before  any   of  the  Company's   potential  products  can  be
commercialized, any related patent may expire, or remain in existence for only a
short period following  commercialization, thus  reducing any  advantage of  the
patent.  Although the  Company is not  aware of  any claim against  it of patent
infringement, the Company's ability to commercialize its products will depend on
not  infringing  the  patents  of  others.  Litigation  concerning  patents  and
proprietary  technologies can  be protracted  and expensive.  Laws regarding the
enforceability of intellectual property vary from country to country. Therefore,
there can be no  assurance that intellectual property  issues will be  uniformly
resolved, or that local laws will provide the Company with consistent rights and
benefits.  In addition, there can be no assurance that others will not be issued
patents which  may  prevent  the  sale of  the  Company's  products  or  require
licensing  and the payment of fees or royalties  by the Company in order for the
Company to be able to market certain products.
 
     The Company  currently  is  the exclusive  and  non-exclusive  licensee  of
various  oncological and biotechnological products and technologies. The Company
may in the future be required or may desire to obtain other licenses to develop,
manufacture and  market  other products  or  to market  products  in  additional
territories, the rights to which may be held by additional parties. There can be
no  assurance that licenses will be obtainable on commercially reasonable terms,
if at all, or that any licensed patents or proprietary rights will be valid  and
enforceable.  Bioferment and  Bigmar Pharmaceuticals  have the  rights to patent
applications for  the  culture  media  used for  the  process  of  manufacturing
recombinant  urokinase that were filed on July  11, 1993. Cerbios Pharma has the
rights to patent applications for sodium leucovorin that were filed on  February
14, 1994. See ' -- Proposed Products.'
 
     To  the extent that consultants, key employees or other third parties apply
technological information independently developed  by them or  by others to  the
Company's  projects, third parties may own all or part of the proprietary rights
to such  information,  and  disputes  may  arise as  to  the  ownership  of  the
proprietary rights to such information which may not be resolved in favor of the
Company.  To  the  extent that  the  Company  requires rights  to  any resulting
technologies, it may be necessary to negotiate additional license agreements  or
the   Company  may   be  unable   to  utilize   such  technologies.   See  'Risk
Factors -- Uncertain Protection of Patents and Proprietary Rights.'
 
GOVERNMENTAL REGULATIONS
 
     UNITED STATES. The  Company's research and  development activities and  the
production  and  marketing  of the  Company's  licensed and  owned  products and
proposed products are subject to regulation for safety, efficacy and  compliance
with   a  wide  range  of   regulatory  requirements  by  numerous  governmental
authorities in the United States, in  states thereof and in other countries.  In
the  United States, drugs are subject to  rigorous FDA review. The Federal Food,
Drug, and Cosmetic Act
 
                                       43
 <PAGE>
<PAGE>
and other Federal  statutes and  regulations govern or  influence the  research,
testing,   manufacture,  safety,  labeling,  storage,  recordkeeping,  approval,
distribution,  reporting,   advertising   and  promotion   of   such   products.
Noncompliance  with applicable requirements can  result in recall, injunction or
seizure of products, refusal to permit  products to be imported into the  United
States,  refusal  of  the  government  to  approve  or  clear  product  approval
applications or to allow the Company to enter into government supply  contracts,
withdrawal of previously approved applications and criminal prosecution.
 
     In  order to obtain FDA approval of a drug, companies must generally submit
proof of  safety  and efficacy.  In  some  cases such  proof  entails  extensive
clinical and preclinical laboratory tests. The testing, preparation of necessary
applications  and processing of  those applications by the  FDA is expensive and
may take several years to complete. There is no assurance that the FDA will  act
favorably  or in  a timely manner  in reviewing submitted  applications, and the
Company may encounter significant difficulties or costs in its efforts to obtain
FDA approvals  which could  delay or  preclude the  Company from  marketing  any
products  it may  develop. The  FDA may  also require  postmarketing testing and
surveillance of approved products, or  place other conditions on the  approvals.
These  requirements could cause it to be more difficult or expensive to sell the
products, and  could  therefore restrict  the  commercial applications  of  such
products.  Product  approvals may  be  withdrawn if  compliance  with regulatory
standards is not maintained  or if problems  occur following initial  marketing.
For  patented  products  or  technologies, delays  imposed  by  the governmental
approval process may materially reduce the period during which the Company  will
have  the exclusive right  to exploit such  technologies; however, an additional
period of up  to five  years may  be added to  the term  of the  patent in  such
circumstance.
 
     New  Drug Application ('NDA'). Generally, with respect to drugs with active
ingredients not  previously approved  by FDA,  a prospective  manufacturer  must
conduct and submit to FDA adequate and well-controlled clinical studies to prove
that  drug's  safety  and efficacy.  Currently,  FDA  approval of  an  NDA takes
approximately two to three years on average after its initial submission to FDA,
based on information published by FDA.
 
     Following drug discovery,  the steps required  before a new  pharmaceutical
product  may be marketed in the United States include (1) preclinical laboratory
and animal tests, (2) the  submission to the FDA of  an application for an  IND,
(3)  clinical and  other studies  to assess  safety and  parameters of  use, (4)
adequate and  well-controlled  clinical  trials  to  establish  the  safety  and
effectiveness  of the drug, (5) the submission of an NDA to the FDA, and (6) FDA
approval of the NDA prior to any commercial sale or shipment of the drug.
 
     Typically, preclinical  studies  are conducted  in  the laboratory  and  in
animal  model systems to gain preliminary information on the drug's pharmacology
and toxicology and to identify any potential safety problems that would preclude
testing in humans. The results of these studies are submitted to the FDA as part
of the IND application. Testing in humans may commence 30 days after  submission
of  the IND  unless the  FDA places the  IND on  'clinical hold.'  A three phase
clinical trial program is usually required for FDA approval of a  pharmaceutical
product.  Phase I clinical  trials are designed to  determine the metabolism and
pharmacologic effects of the  drug in humans, the  side effects associated  with
increasing  doses, and, possibly, to obtain early indications of efficacy. These
studies generally involve a small number of healthy volunteer subjects, but  may
be  conducted in people with the disease the drug is intended to treat. Phase II
studies are conducted to evaluate the effectiveness of the drug for a particular
indication and thus involve patients with the disease under study. These studies
also provide evidence of the short  term side effects and risks associated  with
the  drug. Phase III  studies are generally designed  to provide the substantial
evidence of safety and effectiveness of a drug required to obtain FDA  approval.
They  often involve a  substantial number of patients  in multiple study centers
and may  include chronic  administration of  the  drug in  order to  assess  the
overall  benefit-risk  relationship of  the  drug. Upon  completion  of clinical
testing which demonstrates that the product is safe and effective for a specific
indication, an  NDA may  be  submitted to  the  FDA. This  application  includes
details  of  the manufacturing  and testing  processes, preclinical  studies and
clinical trials. The  FDA closely  monitors the progress  of each  of the  three
phases  of  clinical testing  and may,  at  its discretion,  re-evaluate, alter,
suspend or terminate the testing based on the data that have been accumulated to
that point and its assessment of the risk/benefit ratio to the patient.  Typical
estimates of the total time required for
 
                                       44
 <PAGE>
<PAGE>
completing  such clinical testing vary between  four and ten years. The clinical
testing and FDA review process for  new drugs are likely to require  substantial
time,  effort and expense. The  Company anticipates that proprietary oncological
products will be  approved through the  NDA process. There  can be no  assurance
that  any approval will be granted to the  Company on a timely basis, if at all.
The FDA may refuse to approve  an NDA if applicable statutory and/or  regulatory
criteria  are not satisfied,  or may require  additional testing or information.
There can be no assurance that such additional testing or the provision of  such
information,  if  required,  will not  have  a  material adverse  effect  on the
Company. The  regulatory process  can be  modified  by Congress  or the  FDA  in
specific situations.
 
     Abbreviated  New Drug Application ('ANDA').  The Drug Price Competition and
Patent Term  Restoration  Act of  1984  ('Drug  Price Act')  established  a  new
abbreviated  procedure for obtaining  FDA approval for  those generic drugs that
are equivalents of  brand name  drugs. For drugs  that contain  the same  active
ingredient  as  drugs  already  approved  for  use  in  the  United  States, FDA
ordinarily requires  bioequivalence  data  illustrating that  the  generic  drug
formulation  is, within an acceptable range, equivalent to a previously approved
drug. A generic drug manufacturer is not required to submit the clinical data to
establish the safety and effectiveness of  the product. Instead, the Drug  Price
Act   allows  the  FDA  to  rely   on  bioequivalence  data  to  approve  ANDAs.
'Bioequivalence' compares the bioavailability of  one drug product with  another
and,  when established, indicates that the rate  of absorption and the levels of
concentration of a  generic drug  in the  body are  substantially equivalent  to
those  of the previously approved drug.  The Company anticipates that ANDAs will
be submitted to the FDA for approval of those generic oncological products which
are intended to be marketed in the  United States. See ' -- Proposed  Products.'
According  to information published by FDA, currently it takes approximately one
to three years on average to obtain  FDA approval of an ANDA following the  date
of  its first submission to FDA. Due  to the experience of its senior management
in submitting ANDAs to  the FDA, the  Company believes that it  will be able  to
obtain  FDA approval for each of its proposed oncological products approximately
one year after each ANDA is submitted. Generally, a generic manufacturer may not
submit an ANDA for a period of five years from the date of approval of the brand
name product.
 
     The Drug  Price Act,  in addition  to establishing  a new  ANDA  procedure,
created  new  statutory  protection  for approved  brand  name  drugs.  Prior to
enactment of the Drug Price Act, FDA gave no consideration to the patent  status
of  a previously approved drug in deciding whether to approve an ANDA. Under the
Drug Price Act, however, the effective date  of approval of an ANDA can  depend,
under certain circumstances, on the patent status of the brand name drug.
 
     Additionally,  the Drug Price  Act, in certain  circumstances, provides for
extension of the term of certain patents to cover a drug by up to an  additional
five  years to compensate the  patent holder for the  reduction of the effective
market life of a patent due to the time involved in federal regulatory review.
 
     Good Manufacturing Practices ('GMP').  The Company will  be subject to  the
FDA's  GMP,  GLP and  extensive record  keeping  and reporting  requirements for
manufacturing products for sale in the United States. As a result, the Company's
manufacturing facilities will be subject to periodic inspections by the FDA  and
other United States federal agencies when the Company's products are offered for
sale  in the United States. The Company's operations have not yet been inspected
by the FDA and there can be no  assurance they will pass any inspections by  the
FDA.  The Company has retained independent consultants to assist it in complying
with FDA  standards  including the  GMP  requirements. Failure  to  comply  with
applicable  regulatory requirements  can result  in, among  other things, import
detentions, fines, civil penalties, suspensions or losses of approvals,  recalls
or seizures of products, operating restrictions and criminal prosecutions.

     GERMANY.  In Germany, drugs for human use  can be marketed only if they are
approved in advance either by the  Federal Institute for Medicinal Products  and
Medical  Devices ('BfArM') in Berlin or by the European Union ( 'EU') Commission
after a  substantive  review of  all  safety,  quality and  efficacy  data.  The
application   for  a  marketing  authorization   requires  the  preparation  and
submission of extensive data and files.  The applicant must produce the  results
of  analytical, pharmacological/toxicological  and clinical  studies and related
experts' opinions. The  production of  these data usually  requires a  long-term
pre-clinical  examination phase. The details  of the requirements are prescribed
in  administrative  regulations  such  as  the  Medicinal  Products  Guidelines.
Clinical trials in Germany are monitored by the state authorities.
 
     The  BfArM can reject the application if  the data are incomplete, the drug
product has not been  sufficiently examined, the product  does not conform  with
the  acknowledged  pharmaceutical  quality  rules,  effectiveness  has  not been
established, or there is  a suspicion of unacceptable  side effects. In  theory,
once  a complete application has been submitted to the BfArM, a decision must be
issued within  four  months,  in  exceptional  cases  within  seven  months.  In
practice,  however, these terms are not met and a term of review by the BfArM is
expected to take generally three to five years. The marketing authorization of a
new substance triggers fees to  the BfArM of over  $66,000. The exact amount  of
fees  can vary, depending on  the amount of work  required of the authority, the
kind of procedure and the result of such procedure.
 
     For safety  reasons, drug  products are  also subject  to close  monitoring
after approval is granted. There are a variety of restrictions which the federal
agencies  and  the  state authorities  may  impose including  the  withdrawal of
marketing authorizations and the recall of products.
 
     The importation of  drug products  into Germany  from other  EU and  E.E.A.
(European Economic Area) countries does not require special permission. However,
the  product must be approved in Germany.  Approval of the drug product in other
EU member states does  not replace German approval.  The importer must obtain  a
separate approval for the repackaging and labeling of imported products.
 
     Sales  of high-price pharmaceuticals (such  as oncology drugs) are affected
by parallel imports and re-imports.  Independent importers purchase products  in
the producing EU country, ship them to Germany and, in most cases, offer them at
far  lower prices  than the  manufacturers of  the original  preparations and/or
their official  importers. The  European Court  of Justice  has ruled  that  the
importing member state may not prohibit parallel imports.
 
     Where  a drug product  has not been  produced in an  EU country or imported
through another EU member  country (such as from  Switzerland or the U.S.),  the
importer  must obtain special  permission to import  the product. To  do so, the
importer must produce a certificate from the regulatory authority of the country
where the drug was manufactured showing, among other things, that the product is
approved in that  country and that  it conforms to  applicable standards of  the
World Health Organization ('WHO') or of the Pharmaceutical Inspection Convention
('PIC').  See  'Risk  Factors  --  FDA,  International  and  Other  Governmental
Regulations.'
 
     SWITZERLAND. In Switzerland, approval of  the production and sale of  drugs
for  human use is regulated on a cantonal level rather than a federal level. The
cantons of Switzerland have organized the  IKS as an authority for the  approval
of  pharmaceuticals.  Based  on approval  by  the  IKS, the  cantons  then grant
permission for  the  production  and  sale  of  such  approved  pharmaceuticals.
Theoretically,  each canton is  still entitled to deny  approval of a particular
medication. However, cantons generally  follow the decision of  the IKS as  they
are bound by the Intercantonal Treaty for the Control of Medications.
 
     The  IKS reviews all applicable safety,  quality and effectiveness data, as
well as  data relating  to the  cost  effectiveness of  the product.  To  obtain
approval  from  the  IKS,  the manufacturer  must  submit  analytical, chemical,
pharmacological and toxicological data based on animal trials and human clinical
studies. The  IKS  approves the  manufacturing  of products  only  after  having
checked  the conformity to applicable  standards of the WHO  or the PIC. The IKS
also will inspect the manufacturing facility to determine if the manufacturer is
complying with  good  manufacturing  practices before  approval  is  granted  to
produce   the   drug  product.   For   generic  products,   pharmacological  and
toxicological data are not required to be submitted to the IKS. To date, all  of
the  Company's pharmaceutical  products which have  been approved by  the IKS to
date are generic products.

     RECENT EU PROCEDURES. On January 1, 1995, the EU established new procedures
for the approval of pharmaceuticals, and  a new coordinating body, the EMEA  was
created.  Germany is a member of the EU;  Switzerland is not an EU member. Under
the new procedures, which are  compulsory for biotechnological preparations  and
optional for certain other pharmaceutical products, in particular those with new
chemical  agents,  applications  are  filed  with  the  EMEA  and  are evaluated
scientifically by  the Committee  for Proprietary  Medicinal Products  ('CPMP').
This is known as the centralized procedure. The CPMP consists of representatives
of  the national registration  authorities. For each  application, a Rapporteur,
(i.e. one  of  the  national  authorities) is  appointed  and  has  the  overall
responsibility  for the  review of the  application. The  Rapporteur prepares an
assessment report for  the CPMP.  The EU  Commission will  generally follow  the
CPMP's  scientific  evaluation. If  one or  more member  states objects,  the EU
Council will decide  the matter, otherwise  the decision is  rendered by the  EU
Commission on the basis of the CPMP evaluation.
 
     A  decentralized  approval  procedure  is  used  for  most  other marketing
authorization applications. The applicant submits the application to one  member
state  where the application is reviewed. Once the first marketing authorization
is obtained, the  company files identical  applications in the  other EU  member
states.  The marketing authorities  of such other member  states are supposed to
acknowledge the first decision within 90 days. If there is disagreement  between
the  authorities that  cannot be  resolved, the CPMP  will be  involved and will
issue a  scientific evaluation.  If this  scientific evaluation  is not  further
disputed,  the  EU Commission  will  render a  decision  on this  basis.  If the
disagreement continues, the EU Council will vote to decide the matter.
 
     Because the EMEA  guidelines have been  in effect for  a limited period  of
time, the Company is unable to reliably predict how long it will take on average
for drugs to be approved under these new procedures.
 
THIRD-PARTY REIMBURSEMENT
 
     Successful  commercialization of the Company's own or licensed products may
depend in part on  the availability of  adequate reimbursement from  third-party
health  care payors  such as  Medicare, Medicaid,  and private  insurance plans.
Reimbursement rules vary from payor to payor, and reimbursement also may  depend
upon the setting in which a particular item or service is furnished.
 
     In  general, payors exclude payment for  items and services that are deemed
to be not medically  'reasonable and necessary,' or  which are considered to  be
not  safe  and  effective,  experimental  or  investigative,  or  not  medically
appropriate for the  patient. In making  these determinations, payors  typically
rely  on studies  published in peer-reviewed  medical journals,  the opinions of
recognized medical specialty societies, and  the practices of physicians in  the
local  medical community. Some payors are also beginning to consider the cost of
a new item  or service  in comparison  to existing  alternatives in  determining
whether  and how much they will reimburse for a new technology. FDA clearance or
approval to  begin  marketing  a drug  generally  is  required by  payors  as  a
condition of coverage, but such clearance or approval alone does not assure that
the payor will reimburse for the drug treatment.
 
     Most  medical procedures involve payment for  the physician service and, in
cases where the service is provided  outside of the physician's office,  payment
for  the facility  costs, including supplies,  furnished in  connection with the
procedure. Medicare,  which  is  a Federal  government  program  that  primarily
reimburses health care furnished to the elderly and disabled, pays for physician
services  based on a physician fee schedule,  which assigns a payment weight for
each covered physician procedure.
 
     The trend towards  managed health care  and the concurrent  growth of  HMOs
which  could  control or  significantly influence  the  purchase of  health care
services and products, as well as  legislative proposals to reform health  care,
may  all result  in lower  prices for  the Company's  products. There  can be no
assurance that  the  Company's products  will  be considered  cost-effective  by
third-party  payors,  that  reimbursement  will be  available  or,  if currently
available, will continue to be available, or that payors' reimbursement policies
will not adversely affect the Company's ability to sell products on a profitable
basis, if at all. The cost  containment measures that health care providers  are
instituting in the face of the uncertainty and the ultimate effect of any health
care  reform could have an  adverse effect on the  Company's ability to sell its
products and may have a material adverse effect on the Company.

     Virtually every  state as  well as  the District  of Columbia  has  enacted
legislation permitting the substitution of equivalent generic prescription drugs
for  brand  name drugs  where authorized  or not  prohibited by  the prescribing
physician and  currently  13 states  mandate  generic substitution  in  Medicaid
programs.
 
     In  Germany, about  90% of the  population are members  of statutory health
insurance  programs.  These  health   insurance  providers  are  public   bodies
independent  from  the  government  and  are  funded  equally  by  employers and
employees. Their catalogue of services for which they will provide reimbursement
is widely influenced by government regulations. Managed Care and HMO's are still
unknown in Germany although various elements  of these systems will probably  be
adopted  in the  future. The economic  success of  a drug product  in Germany is
widely dependent upon acceptance of the  drug by the statutory health  insurance
providers.
 
     Certain  drugs  are generally  excluded  from reimbursement,  however. This
includes medications to treat minor diseases like colds and influenza and  drugs
which   have  been  determined   by  the  Federal  Ministry   of  Health  to  be
'uneconomical,'  e.g.,   medicinal  products   with  more   than  three   active
ingredients.  The  Federal  Ministry  of  Health  is  authorized  to  amend this
'negative  list'  at  any  time.  Health  insurance  providers  generally   deny
reimbursement for drugs used in clinical trials. Although drugs can generally be
prescribed  by a doctor  off label, i.e., beyond  their approved indication, and
still be  reimbursed, there  are cases  where the  reimbursement of  oncological
drugs off-label was denied on the basis that the treatment was experimental.
 
     The   health  insurance  providers  are  also  authorized  to  set  maximum
reimbursement levels for generic drugs. As  soon as two products with  identical
or  chemically similar  ingredients or  similar therapeutic  effects are  on the
market, the health insurance providers  may set a maximum reimbursement  amount.
This  amount will  usually be an  average of  the lowest and  the highest price.
Typically, the maximum reimbursement is fixed  on the basis of the lowest  price
plus  1/3 of the price  range to the most expensive  product. About 70% of drugs
sold in Germany  are subject to  maximum reimbursement. So  far, no  oncological
products  have been affected by a  maximum reimbursement cap. This may, however,
change at any  time. A  manufacturer is  legally free  to continue  to sell  its
products  at higher than the maximum  reimbursement rate, but patients must then
pay the difference. So  far, the Company believes  no manufacturer has tried  to
sell its products at prices exceeding the maximum reimbursement. If the products
of  the  Company  become  subject  to a  maximum  reimbursement  rate,  this may
adversely affect  the prices  the company  will  be able  to charge.  See  'Risk
Factors  -- Dependence on Third-Party Reimbursement; Price Controls; Health Care
Reform.'
 
     In addition  to  maximum  reimbursement  caps,  pharmaceutical  prices  are
subject  to statutory limitations on  the amounts that can  be spent on drugs by
the statutory  health  insurance  providers. As  a  consequence,  pharmaceutical
prices  decreased in  the last  several years  and may  decrease further  in the
future.
 
     In Switzerland, reimbursement for pharmaceuticals is regulated on a federal
level. There are  two categories of  drugs subject to  reimbursement. The  first
category  consists of medications which are required to be reimbursed by private
health insurers. The  second category contains  specialty medications for  which
reimbursement  is  recommended.  In  practice,  private  health  insurers  grant
reimbursement for the specialty products on the recommended list.
 
ENVIRONMENTAL REGULATIONS
 
     In Switzerland, Bigmar Pharmaceuticals and Bioren are subject to applicable
environmental laws such  as the Environment  Protection Act of  1983, the  Water
Protection  Act of  1991 and  the Toxic Substance  Act of  1969, as  well as all
applicable regulations. Swiss environmental protection laws govern, among  other
things,  all emissions  to the  air, soil and  water, waste  water discharge and
solid and  hazardous  waste  disposal. Bigmar  Pharmaceuticals  and  Bioren  are
subject  periodically  to  environmental  compliance  reviews  by  various Swiss
regulatory offices.
 
     The Company believes its facilities  in Switzerland are in compliance  with
applicable  environmental  laws.  However, environmental  laws  have  changed in
recent years  and  the Company  may  become subject  to  increasingly  stringent
environmental  standards in  the future. While  the Company  anticipates that it
 
                                       48
 <PAGE>
<PAGE>
may from  time  to time  incur  expenditures in  connection  with  environmental
matters,  it  does  not  anticipate making  substantial  expenditures  for those
matters within the next twelve months and  beyond that is unable to predict  the
extent or timing of future expenditures which may be required in connection with
complying with environmental laws.
 
PRODUCT LIABILITY AND INSURANCE
 
     The testing, clinical trials, manufacturing, and marketing of the Company's
products  and proposed products involve the  inherent risks of product liability
claims against the  Company. The Company  currently maintains product  liability
insurance  coverage  on IV  Solutions  in the  amount  of $45,000,000,  but such
insurance is expensive, subject to various exclusions and may not be  obtainable
or maintainable by the Company in the future on terms acceptable to the Company.
There  can be  no assurance that  the amount and  scope of any  coverage will be
adequate to protect the Company in the  event that a product liability claim  is
successfully  asserted  against the  Company. Products,  such  as those  sold or
proposed to be  sold by the  Company, may  be subject to  recall for  unforeseen
reasons. A recall of the Company's products could have a material adverse effect
on the Company and its reputation.
 
     Rules  on strict liability  of drugs are  in effect in  Germany. The person
responsible for placing the product on the market (who can, but need not be, the
manufacturer) is liable. Only personal injuries are recoverable, and there is no
mandated compensation for pain or  suffering. The maximum amount recoverable  by
an individual is DM 1 million (approximately US $666,000).
 
     The  manufacturer or the person responsible  for placing the product on the
market is obliged  to obtain insurance  coverage against potential  liabilities.
This  obligation can  be fulfilled  either by  entering into  a contract  with a
German insurance company,  or by  obtaining a  confirmation of  coverage from  a
credit  institution in Germany  or within the EU.  The German insurance industry
has created a  so-called 'pharma  pool.' This working  relationship enables  all
major  German insurance  companies to pool  the risks from  the statutory strict
liability and therefore provide affordable insurance.
 
     Compensation for pain and suffering  or for personal damages exceeding  the
amounts  set forth above can only be demanded on the basis of tort rules as laid
down in the Civil Code. If a claim is sustained there is unlimited liability. No
compulsory insurance coverage  is prescribed by  statute. Compensation for  pain
and suffering can be assessed by the courts but usually remains below the levels
under United States law.
 
     In   Switzerland,   there  is   no  special   product  liability   law  for
pharmaceuticals. The  Swiss federal  product liability  law, which  covers  drug
products,  provides  that  manufacturers  are subject  to  strict  liability for
injuries caused by defective products.
 
FACILITIES
 
     The Company's  principal executive  offices  are located  in  approximately
1,440  square  feet  in Columbus,  Ohio.  The  Company entered  into  a sublease
agreement, dated March 1,  1996, with Cernitin  America, Inc. ('Cernitin').  The
sublease  terminates  on February  28,  1998. The  sublease  is at  a  rental of
approximately $22,315 per annum. Mr. Tramontana was the President and a director
of Cernitin  and Michael  K. Medors  was the  treasurer and  general manager  of
Cernitin  at the  time of  the negotiation  and execution  of the  sublease. See
'Certain Transactions.'
 
     The Company owns  two pharmaceutical  plants, the Bigmar  Facility and  the
Bioren Facility.
 
   
     During 1995, Bigmar Pharmaceuticals purchased the Bigmar Facility, a 25,000
square  foot facility in Barbengo, Switzerland, for developing and manufacturing
oncological products. The Bigmar Facility  also houses warehousing and  storage,
manufacturing,  labeling  and packaging,  and administrative  and record-keeping
areas. The Bigmar Facility and the equipment contained therein is subject to two
bank loans in the principal amounts of approximately $1,551,000 and  $1,974,000,
respectively.  The loans  are secured  by mortgages  on the  Bigmar Facility and
certain machinery. Interest on the loans is payable at a rate of up to 6.5%  per
annum  until December 31, 1997.  The principal amounts of  such loans are due on
December 31, 1997 and may be extended  by an agreement between the parties.  The
first  loan is  pursuant to a  bank commitment  with a limit  of $1,847,187 from
which the Company may draw. The second loan has a limit of $2,749,790 from which
the Company may draw. See 'Management's

 <PAGE>
<PAGE>
Discussion   and   Analysis    of   Financial   Condition    and   Results    of
Operations -- Liquidity and Capital Resources.' The Bigmar Facility is currently
being equipped and the Company will not begin manufacturing oncological products
until  the facility  is fully operational  and regulatory  approval is obtained,
which the Company believes  will occur in  the last quarter  of 1996. See  'Risk
Factors -- Manufacturing Facilities for Proposed Products.'
 
   
     The Bioren Facility is a 57,000 square foot facility in Couvet, Switzerland
that   houses  manufacturing  operations,   laboratory  facilities  for  quality
assurance  and  quality   control  activities,  including   batch  testing   and
multiple-batch  stability testing operations, labeling and packaging operations,
warehousing and storage operations,  administrative and record-keeping areas.  A
25,000  square foot area in the Bioren Facility will be used as a dedicated area
for scaling up  the development  and manufacturing  supporting (rescue  therapy)
oncological  products, such as  sodium leucovorin. A 21,000  square foot area in
the Bioren Facility  is used  for manufacturing  and marketing  IV Solutions.  A
portion  of the Bioren  Facility is leased  to an unaffiliated  third party on a
year-to-year basis.  The  Bioren  Facility  is subject  to  a  mortgage  in  the
approximate  principal amount of $2,500,000 which is due on May 16, 1999 and may
be extended by an agreement between the parties. Interest until May 16, 1999  is
5%  per annum. The Bioren Facility is  also subject to a second mortgage payable
to Galenica  in  the amount  of  $1,679,261.  This second  mortgage  is  payable
$419,815 in 1997, $419,815 in 1998 and $839,631 in 1999. Interest on this second
mortgage  is  at a  variable  rate which  is currently  5.5%  and is  subject to
adjustment based  upon  commercial  mortgage  rates.  In  addition,  the  Bioren
Facility  is subject to a third mortgage  payable to Galenica securing a debt of
$1,847,187 which debt  will be paid  out of  the proceeds of  the Offering.  See
'Management's  Discussion  and Analysis  of Financial  Condition and  Results of
Operations -- Liquidity and Capital Resources.'
    
 
     The Company believes that its facilities are sufficient for its current and
reasonably anticipated operations.  The Company  owns all  of its  manufacturing
equipment,  subject to  the mortgage  referred to  above, and  believes that its
equipment is well  maintained and suitable  for its requirements.  Additionally,
the Company maintains property and casualty insurance in amounts it believes are
sufficient  and  consistent  with  practices  for  firms  of  its  size  in  the
prescription drug industry. See ' -- Manufacturing and Suppliers.'
 
LEGAL PROCEEDINGS
 
     The Company is not a party to any material legal proceedings.
 
HUMAN RESOURCES
 
     As of May  28, 1996,  the Company  employed 40  full-time employees,  three
employees  in development,  30 employees  in manufacturing  and quality control,
three  employees   in  marketing,   and  four   employees  in   management   and
administration.  The Company  has one  part-time employee  providing secretarial
services and  three  consultants  providing technical  services  (not  including
medical  and scientific advisors). Substantially  all of the Company's employees
are located  in  Switzerland. The  Company  believes  that the  success  of  its
business  will depend,  in part,  on its  ability to  attract and  retain highly
qualified personnel.
 
     During the  12-month  period  following completion  of  the  Offering,  the
Company  intends to  hire approximately  15 additional  employees, including one
employee in the area of marketing, 10 employees in the area of development,  two
employees  in the areas of manufacturing and quality control and one employee in
the area  of management  and  administrative services.  See 'Use  of  Proceeds,'
' -- Research and Development,' and 'Management.'
 
     The  Company's  employees  are not  a  party to  any  collective bargaining
agreements. The Company believes that it has good relations with its employees.

     The Company intends to enter into scientific advisory agreements ('Advisory
Agreements')  with each of the Scientific  Advisors which will generally require
the Scientific Advisor to: (i)  advise the Company of  advances in his field  of
expertise;  (ii)  consult  with the  Company;  (iii) assess  the  feasibility of
research and  development programs  under consideration  by the  Company in  his
field;  and (iv) offer guidance for future research and clinical applications of
the Company's technology in his field. Each Advisory Agreement will provide that
the Scientific Advisor agree  to meet individually and  in groups to advise  the
Company  on its research,  development, operations and  commercialization of its
technology, consult  on  the  Company's  projects and  attend  meetings  of  the
Scientific  Advisors. Generally, any further activities if requested shall be on
an 'as available'  basis and at  an agreed  upon fee. The  agreements with  each
Scientific Advisor will contain confidentiality provisions.
    
 
   
     The  Scientific Advisors are not expected to otherwise actively participate
in the  development of  the Company's  technologies or  products. Each  Advisory
Agreement  will  be  for a  term  of  three years.  In  consideration  for their
services, each Scientific Advisor  will receive a fee  of $1,000 per annum,  and
each  will be reimbursed for reasonable  expenses incurred in the performance of
their duties  for  the  Company.  In addition,  upon  the  consummation  of  the
Offering,  each Scientific  Advisor will  be granted  options to  purchase 3,000
shares of Common Stock, under  the Option Plan, at  an exercise price per  share
equal to the initial public offering price. The options will vest in three equal
installments,  the  first  commencing  one  year  following  the  date  of  this
Prospectus and  the  second  and  third  commencing  on  the  second  and  third
anniversary  dates  of  the date  of  this  Prospectus, each  of  which  will be
exercisable for  a period  of three  years following  the date  of vesting.  The
Advisory  Agreements will provide for indemnification of the Scientific Advisor,
against any liabilities arising from their good faith services thereunder.
    
 
   
     The Company's  Scientific Advisors  are employed  on a  full-time basis  by
employers  other  than  the  Company,  and  certain  of  those  individuals have
additional consulting  or other  advisory  arrangements. Accordingly,  they  are
expected to devote only a small portion of their time to the Company.
    
 
LIMITATION OF LIABILITY AND INDEMNIFICATION MATTERS
 
     The  Company  has  included  in  its  Restated  Certificate  provisions  to
indemnify its directors and officers to the fullest extent permitted by Delaware
law. The Company's  Restated Certificate also  includes provisions to  eliminate
the  personal liability of  the Company's directors and  officers to the fullest
extent permitted  by Delaware  law. Under  current law,  such exculpation  would
extend  to an officer's or director's breaches of fiduciary duty, except for (i)
breaches of  such person's  duty of  loyalty, (ii)  those instances  where  such
person  is found not to have acted in good faith and (iii) those instances where
such person received an improper personal benefit as the result of such breach.
 
     The Company's Restated  By-Laws ('By-Laws')  provide that  the Company  may
indemnify  any  person, including  officers and  directors,  with regard  to any
action or proceeding to the fullest extent permitted by Delaware law.
 
                                       54
 <PAGE>
<PAGE>
     The Company will enter into an indemnification agreement  ('Indemnification
Agreement')  with  each  of  its directors  and  officers.  Each Indemnification
Agreement will provide that  the Company will  indemnify the indemnitee  against
expenses,  including reasonable attorneys' fees, judgments, penalties, fines and
amounts paid in settlement actually and reasonably incurred by him in connection
with any civil or  criminal action or administrative  proceeding arising out  of
his  performance of his  duties as a  director or officer,  other than an action
instituted by the director or officer. Such indemnification is available if  the
indemnitee  acted in good faith and in a  manner he reasonably believed to be in
or not opposed to the  best interests of the Company,  and, with respect to  any
criminal  action, had no  reasonable cause to believe  his conduct was unlawful.
Each Indemnification Agreement also will require that the Company indemnify  the
director  or other party thereto in all cases to the fullest extent permitted by
applicable law. The term of each Indemnification Agreement will be the later  of
(i) 10 years after the date that the indemnitee ceases to serve as a director or
officer  of the Company,  or (ii) the  final termination of  all proceedings, as
defined in the  Indemnification Agreement,  in which the  indemnitee is  granted
rights of indemnification.
 
     Each  Indemnification Agreement will permit the indemnitee to bring suit to
seek recovery  of amounts  due  under such  Indemnification Agreement  and  will
require  that the Company indemnify  the director or other  party thereto in all
cases to the fullest  extent permitted by applicable  law. Although the  Company
intends  to seek  to obtain directors'  and officers'  liability insurance, such
insurance is generally  very expensive.  If the Company  is not  able to  obtain
director'  and officers' liability insurance to cover such amounts, any payments
made by the  Company under  an Indemnification  Agreement will  have an  adverse
impact on the Company.
 
     It is the position of the Commission that insofar as the Company's Restated
Certificate,  By-Laws or  any Indemnification  Agreement may  be invoked  by any
director, officer  or  stockholder  as  a means  of  indemnifying  them  against
liabilities  arising  under the  Securities  Act, that  such  indemnification is
against public  policy as  expressed  in the  Securities  Act and  is  therefore
unenforceable.
 
EXECUTIVE COMPENSATION
 
     The  Company  did  not  pay  any  compensation  exceeding  $100,000  to its
executive officers for the year ended December 31, 1995. John G. Tramontana, the
Company's President and Chief Executive Officer received no compensation  during
this period. See ' -- Employment Agreements.'
 
DIRECTOR COMPENSATION
 
     Directors  of the Company who are not  salaried officers will receive a fee
of $500 for attending each Board meeting or meeting of a committee of the  Board
of  which they are a  member. In addition, all  directors will be reimbursed for
their reasonable out-of-pocket expenses in connection with attending meetings of
the Board  or  any  committee  thereof. All  directors  who  are  not  otherwise
affiliated  with the Company will receive  options to purchase Common Stock. See
' -- Directors Option Plan.'
 
EMPLOYMENT AGREEMENTS
 
     In April 1996, the  Company entered into an  employment agreement with  Mr.
Tramontana  to serve as the Company's President and Chief Executive Officer. The
employment agreement is for a five-year term effective upon consummation of  the
Offering  and is subject to automatic  annual renewal unless earlier terminated.
Pursuant to the terms of this  employment agreement, Mr. Tramontana is  required
to  devote  his full  business  time and  attention  to fulfill  his  duties and
responsibilities to the Company.  Mr. Tramontana will receive  a base salary  of
$200,000  for  the first  year  of the  term  of the  employment  agreement with
subsequent annual cost of  living increases at the  discretion of the  Company's
Board  of Directors. In addition to his  base salary, Mr. Tramontana is entitled
to receive  an  annual bonus,  at  the discretion  of  the Board  of  Directors,
provided  such  bonus  is  equal  to  at  least  25%  of  his  base  salary. Mr.
Tramontana's employment  agreement  provides that  the  Company is  required  to
provide  Mr. Tramontana with an automobile allowance of $6,000 per annum and the
Company is required to obtain  life insurance coverage on  the life and for  the
benefit  of  Mr. Tramontana  in  an amount  equal  to $500,000,  assuming  he is
insurable. Mr. Tramontana will also have the right to participate in all benefit
 
                                       55
 <PAGE>
<PAGE>
   
plans afforded or which may be  afforded to other executive officers during  the
term  of the agreement  including, without limitation,  group insurance, health,
hospital, dental, major  medical, life  and disability  insurance, stock  option
plans  and other similar fringe benefits. If Mr. Tramontana dies or is unable to
perform his duties on account of  illness or other incapacity and the  agreement
is terminated, he or his legal representative shall receive from the Company the
base  salary which would otherwise  be due to the end  of the month during which
the termination  of employment  occurred plus  three additional  months of  base
salary  in the event  of death and six  additional months of  base salary in the
event of illness or other incapacity. The agreement further provides that if the
Company terminates Mr. Tramontana's  employment for cause  or if Mr.  Tramontana
voluntarily  leaves the employment of the  Company, Mr. Tramontana shall receive
his salary through the end  of the month in  which the termination occurred.  If
Mr.  Tramontana's employment  is terminated  by the  Company without  cause, Mr.
Tramontana shall receive from the Company the base salary which would  otherwise
be  due  to the  end of  the month  during which  the termination  of employment
occurred plus  four additional  months.  Mr. Tramontana's  employment  agreement
contains certain confidentiality and non-competition provisions. The Company has
obtained  $2,000,000 of key-person life insurance for the benefit of the Company
on the life of Mr. Tramontana effective on June 15, 1996.
    
 
   
     Upon the consummation of the Offering, the Company intends to enter into an
employment agreement with Mr. Sweeney to  serve as the Company's Vice  President
and  Chief Financial Officer for a two-year  term. Pursuant to the terms of this
employment agreement, Mr. Sweeney will be  required to devote his full time  and
attention  to the Company's business and affairs  and will receive a base salary
of $80,000 for the first year of the term with an annual review of such  salary.
In  addition to  his base  salary, Mr.  Sweeney will  be entitled  to receive an
annual bonus of 15% of his base salary. Mr. Sweeney's employment agreement  will
provide  that the Company is required to  provide Mr. Sweeney with an automobile
allowance of $250 per month. Mr. Sweeney will also have the right to participate
in all  benefit plans  afforded or  which  may be  afforded to  other  executive
officers  during the term of the  agreement including, without limitation, group
insurance,  health,  hospital,  dental,  major  medical,  life  and   disability
insurance,  stock option plans and other  similar fringe benefits. Mr. Sweeney's
employment agreement will  contain certain  confidentiality and  non-competition
provisions.
    
 
OPTION PLAN
 
     In April 1996, the Board of Directors adopted and the stockholders approved
the  Option Plan.  The Option  Plan provides  for the  grant of  incentive stock
options ('ISOs') (within the meaning of Section 422 of the Internal Revenue Code
of 1986, as  amended) and  non-qualified stock options  ('NQSOs') to  directors,
officers  and employees of the Company. The Option Plan further provides for the
grant of NQSOs  to directors  and agents of,  and consultants  to, the  Company,
whether  or not employees of  the Company. The purpose of  the Option Plan is to
attract and retain exemplary directors, employees, agents, and consultants.  All
options  granted under the Option Plan will be  at an exercise price of not less
than the fair market value of the Common Stock on the date of grant. All options
granted under the  Option Plan will  not be transferable  by the optionee  other
than by will, by the laws of descent and distribution or as required by law.
 
     Options  granted under the Option Plan may  not be exercisable for terms in
excess of  10 years  from the  date of  grant. In  addition, no  options may  be
granted  under  the Option  Plan later  than  10 years  after the  Option Plan's
effective date. The total number of shares of Common Stock with respect to which
options will be granted under the Option Plan is 300,000. The shares subject  to
and  available  under the  Option  Plan may  consist, in  whole  or in  part, of
authorized but  unissued stock  or treasury  stock not  reserved for  any  other
purpose.  Any shares subject to an option that terminates, expires or lapses for
any reason, and  any shares  purchased pursuant  to an  option and  subsequently
repurchased  by the Company pursuant to the  terms of the option, shall again be
available for grant under the Option Plan.
 
     The Option Plan is  administered by the Board  of Directors of the  Company
which  determines,  in its  discretion, among  other  things, the  recipients of
grants, whether a grant will consist of ISOs or NQSOs, or a combination thereof,
and the number  of shares of  Common Stock to  be subject to  such options.  The
Board  of Directors of the  Company may, in its  discretion, delegate its power,
duties and
 
                                       56
 <PAGE>
<PAGE>
responsibilities under the Option Plan to a committee consisting of two or  more
directors  who  are 'disinterested  persons' within  the  meaning of  Rule 16b-3
promulgated under the Securities Act of  1934, as amended. The Compensation  and
Stock  Option Committee, which is responsible for administering the Option Plan,
will be composed of Michael K. Medors, Eric M. Chen and Thomas W. D'Alonzo.
 
     The Option  Plan  contains  certain limitations  applicable  only  to  ISOs
granted  thereunder. To the extent  that the aggregate fair  market value, as of
the date of grant, of the shares to which ISOs become exercisable for the  first
time  by an optionee during the calendar  year exceeds $100,000, the ISO will be
treated as a NQSO. In addition, if  an optionee beneficially owns more than  10%
of  the Common Stock  at the time the  individual is granted  an ISO, the option
price per share cannot be less than 110% of the fair market value per share  and
the term of the option cannot exceed five years.
 
DIRECTOR OPTION PLAN
 
     Prior  to the consummation of the Offering,  the Company intends to adopt a
director stock option plan ('Director Option Plan') pursuant to which  directors
who  are  not  otherwise  affiliated  with the  Company  (such  as  employees or
consultants of the  Company, or an  affiliate thereof) will  receive options  to
purchase Common Stock. The purpose of the Director Option Plan is to promote the
overall  financial objectives of the Company  and its stockholders by motivating
directors to achieve long-term growth in  stockholder equity in the Company,  to
further  align  the  interest  of  the directors  with  those  of  the Company's
stockholders and to recruit and retain  the association of these directors.  The
Director  Option Plan will provide for the award of up to an aggregate of 50,000
shares of Common Stock  and will be administered  by the Compensation and  Stock
Option Committee.
 
     The  Director Option Plan  will provide for  (i) the grant  of an option to
purchase 3,000 shares of Common Stock to  each director who was not an  employee
or  consultant of the Company upon the consummation of the Offering and (ii) the
grant of an option to purchase 1,500 shares of Common Stock on the date of  each
regular  annual stockholder meeting to each participant who either is continuing
as a director subsequent  to the meeting  or who is elected  at such meeting  to
serve as a director. Options granted under the Director Option Plan must provide
for the purchase of shares of Common Stock at an exercise price of not less than
the  fair market value of the Common Stock on the date of grant. No option under
the plan may be exercisable  10 years after its  date of grant. Options  granted
under  the Director Option Plan  will not be transferable  by the optionee other
than by will, by the laws of descent and distribution or as required by law.

                              CERTAIN TRANSACTIONS
 
BIOREN ACQUISITION
 
     In June 1995, all of the outstanding capital stock of Bioren was  purchased
by  Bigmar Pharmaceuticals in  the Bioren Acquisition  for an aggregate purchase
price of approximately $9.4 million, consisting of approximately $5.2 million in
cash, and the assumption of certain of the seller's liabilities in the aggregate
principal amount of approximately $4.2 million. In addition, in connection  with
the  Bioren Acquisition, Bigmar Pharmaceuticals became a guarantor on a new bank
loan to Bioren in the principal amount of $2.6 million, which was collateralized
by the Bioren Facility,  and provided a  guarantee of a  second mortgage in  the
aggregate principal amount of approximately $1.7 million on the Bioren Facility.
In  addition, in  June 1995 Bigmar  Pharmaceuticals sold one-half  of its equity
interest of Bioren to  the Bioren Holders for  approximately $2.6 million.  This
sale  included  500  shares  (10%  of Bioren's  outstanding  stock)  to  John G.
Tramontana, the Company's Chairman of  the Board, President and Chief  Executive
Officer, for $500,000.
 
CONTRIBUTION
 
     On   April  8,  1996,  in  the  Contribution,  all  of  the  then  existing
stockholders of the Company contributed 99%  of the shares of Common Stock  then
owned by each of these stockholders to the Company for no cash consideration.
 
EXCHANGE
 
   
     On  April  9, 1996,  in the  Exchange, the  Bioren Holders  exchanged their
capital stock  in Bioren  (representing 50%  of the  outstanding Bioren  capital
stock)  for 350,312 shares  of Common Stock  of the Company  with an approximate
fair market value (based on an estimated initial public offering price of  $8.00
per  share)  of  $2,802,496  and  the  stockholders  of  Bigmar  Pharmaceuticals
exchanged all  of the  capital  stock of  Bigmar Pharmaceuticals  for  2,000,938
shares  of Common  Stock of  the Company with  an approximate  fair market value
(based on an  estimated initial  public offering price  of $8.00  per share)  of
$16,007,504.
    
 
TRANSACTIONS WITH PRINCIPAL STOCKHOLDERS
 
     In  November 1995, Bioren entered into an exclusive distribution and supply
agreement with  Sapec  and  Bigmar Pharmaceuticals  entered  into  an  exclusive
distribution  and  supply  agreement  with Cernelle,  each  relating  to certain
oncological products. Pursuant to the terms of each agreement, Bioren or  Bigmar
Pharmaceuticals,  as  the case  may  be, is  obligated  to pay  either  Sapec or
Cernelle a one-time fee of $100,000 upon notification by Sapec or Cernelle  that
their  respective oncological products  are ready for  shipment. In addition, in
November 1995,  Bigmar Pharmaceuticals  entered into  an exclusive  license  and
supply  agreement with Bioferment relating to certain biotechnological products.
Pursuant to  the  terms  of  this agreement,  Bigmar  Pharmaceuticals  will  pay
Bioferment  a license  fee aggregating $500,000  upon the  completion of certain
regulatory milestones. The  full amount of  this license fee  shall be  credited
against  future royalty obligations  due to Bioferment  under the agreement. See
'Business --  Products.'  At  the  time of  negotiation  and  execution  of  the
foregoing  agreements, John G. Tramontana, the  Company's Chairman of the Board,
President, and Chief Executive  Officer, was the Chief  Operating Officer and  a
director  of Cerbios Pharma, Chairman of the Board of Cernelle and a director of
Chemholding, a principal  stockholder of  the Company. Chemholding  is the  sole
stockholder  of  Cerbios Pharma  of which  Sapec  and Bioferment  are divisions.
Cerbios Pharma is the sole stockholder of Cernelle. Certain stockholders of  the
Company  own  in  the  aggregate  approximately  80%  of  the  capital  stock of
Chemholding. John G.  Tramontana is  not a stockholder  of Chemholding,  Cerbios
Pharma  or Cernelle. The Company believes that the terms of these agreements are
no more favorable to the Company or the other parties thereto than they would be
to unaffiliated third parties.  See 'Risk Factors  -- Reliance on  Collaborative
Arrangements; Management Affiliations with Collaborators.'

     In  1995, Unione Farmaceutica SA, which is owned by certain stockholders of

     Certain of the transactions set forth  above have been entered into by  the
Company  with certain persons who, at the  time of such transactions, might have
been deemed control persons  or affiliates of  the Company. Notwithstanding  the
foregoing, the Company believes that the terms of these transactions are no less
favorable  to the  Company than it  would have obtained  from unaffiliated third
parties. The Company anticipates that all future transactions and loans  between
the  Company and its officers, directors, 5% stockholders and affiliates will be
on terms  no less  favorable  than could  be  obtained from  unaffiliated  third
parties  and that such transactions and loans  will be approved by a majority of
the independent disinterested directors of the Company.

                          DESCRIPTION OF CAPITAL STOCK
 
     The authorized capital stock of the Company consists of 20,000,000  shares,
of  which 15,000,000  shares are  Common Stock, par  value $.001  per share, and
5,000,000 are Preferred Stock,  par value $.001 per  share. There are  2,375,000
shares  of Common Stock  held of record  by seven stockholders  and no shares of
Preferred Stock outstanding. All information in this Prospectus gives effect  to
the  following events: (i) the Contribution, on April 8, 1996, to the Company of
99% of the shares of Common Stock then owned by the stockholders of the Company;
(ii) the Exchange, on April 9,  1996, whereby Bigmar Pharmaceuticals and  Bioren
became subsidiaries of the Company; (iii) a Reverse Split, effected on April 16,
1996,  of the outstanding  shares of Common  Stock; and (iv)  an increase in the
number of  authorized shares  of  Common Stock  from 10,000,000  to  15,000,000,
effected  on April 16, 1996. Upon consummation of the Offering, 3,625,000 shares
of Common Stock  will be  issued and outstanding,  assuming no  exercise of  the
Underwriters'  over-allotment  option and  no  exercise of  the Representative's
Warrants.
 
   
     Prior to the Offering, there has been no public market for the Common Stock
of the Company. Subject to official notice of issuance, the Company has received
approval to have the Common Stock  quoted on the Nasdaq SmallCap MarketSM  under
the  trading symbol  'BGMR' and  listed on the  Boston Stock  Exchange under the
trading symbol 'BIG.'
    
 
     The following description of the capital  stock of the Company and  certain
provisions of the Company's Restated Certificate and By-Laws is a summary and is
qualified  in its  entirety by  the provisions  of the  Restated Certificate and
By-Laws, which  have  been  filed  as exhibits  to  the  Company's  Registration
Statement, of which this Prospectus forms a part.
 
COMMON STOCK
 
     The issued and outstanding shares of Common Stock are, and the shares being
offered  hereby will, upon  payment therefor, be validly  issued, fully paid and
nonassessable. Subject to the rights of the holders of the Preferred Stock,  the
holders  of outstanding shares of Common Stock are entitled to receive dividends
out of assets legally available  therefor at such times  and in such amounts  as
the   Board  of   Directors  may  from   time  to  time   determine.  See  'Risk
Factors -- Restrictions on Retained Earnings' and 'Dividend Policy.' The  shares
of  Common Stock are neither redeemable nor convertible, and the holders thereof
have no preemptive  or subscription  rights to  purchase any  securities of  the
Company. Upon liquidation, dissolution or winding up of the Company, the holders
of  Common Stock are  entitled to receive,  pro rata, the  assets of the Company
which are legally  available for distribution,  after payment of  all debts  and
other  liabilities and subject to  the prior rights of  any holders of Preferred
Stock then outstanding. Each  outstanding share of Common  Stock is entitled  to
one  vote  on all  matters  submitted to  a vote  of  stockholders. There  is no
cumulative voting for the election of directors.
 
PREFERRED STOCK
 
     The Company's Restated  Certificate authorizes  the Board  of Directors  to
issue   the  Preferred  Stock  in  classes   or  series  and  to  establish  the
designations, preferences, qualifications, limitations  and restrictions of  any
class  or series with respect to the rate and nature of dividends, the price and
terms and conditions on which shares  may be redeemed, the terms and  conditions
for  conversion or exchange into any other class or series of such stock, voting
rights and other  terms. The  Company may, without  approval of  the holders  of
Common  Stock, issue Preferred  Stock which has  voting, dividend or liquidation
rights superior to those of the Common Stock and which may adversely affect  the
rights  of  holders of  Common  Stock. The  issuance  of Preferred  Stock, while
providing  flexibility  in  connection  with  possible  acquisitions  and  other
corporate purposes, could, among other things, adversely affect the voting power
of  the holders of Common Stock and could have the effect of delaying, deferring
or preventing a change in control of the Company. See 'Risk Factors --  Possible
Adverse Effects of Issuance of Preferred Stock.'

OPTIONS AND WARRANTS
 
     As  of  the  date of  this  Prospectus,  other than  as  described  in this
Prospectus, there will  be no outstanding  options or warrants  to purchase,  or
securities convertible into, Common Stock of the Company.
 
DELAWARE ANTI-TAKEOVER LAW
 
     The  Company  is subject  to  Section 203  ('Section  203') of  DGCL which,
subject to certain exceptions, prohibits a Delaware corporation from engaging in
any 'business combination'  with any  'interested stockholder' for  a period  of
three  years  following  the date  that  such stockholder  became  an interested
stockholder, unless:  (i) prior  to such  date, the  Board of  Directors of  the
corporation,  approved either the business  combination or the transaction which
resulted in  the  stockholder  becoming an  interested  stockholder;  (ii)  upon
consummation  of the transaction  which resulted in  the stockholder becoming an
interested stockholder, the  interested stockholder  owned at least  85% of  the
voting  stock  of  the  corporation  outstanding  at  the  time  the transaction
commenced,  excluding  for  purposes  of   determining  the  number  of   shares
outstanding  those shares owned  by persons who are  directors and also officers
and by employee stock plans in which employee participants do not have the right
to determine confidentially  whether shares  held subject  to the  plan will  be
tendered  in a tender or exchange offer; or (iii) on or subsequent to such date,
the business combination is approved by the Board of Directors and authorized at
an annual or special meeting of stockholders, and not by written consent, by the
affirmative vote of at least  66 2/3% of the  outstanding voting stock which  is
not  owned by  the interested stockholder.  Under Section  203, the restrictions
described above also do not apply  to certain business combinations proposed  by
an  interested stockholder following the announcement  or notification of one of
certain extraordinary transactions  involving the corporation  and a person  who
had  not been an interested  stockholder during the previous  three years or who
became an  interested  stockholder  with  the approval  of  a  majority  of  the
corporation's  directors and which transaction is approved or not opposed by the
majority of the board of directors then in office.
 
     Section 203 generally defines  a business combination  to include: (i)  any
merger   or  consolidation   involving  the   corporation  and   the  interested
stockholders; (ii) any  sale, transfer, pledge  or other disposition  of 10%  or
more  of  the assets  of the  corporation to  the interested  stockholder; (iii)
subject to certain exceptions, any transaction which results in the issuance  or
transfer  by the corporation of  any stock of the  corporation to the interested
stockholder; (iv) any transaction involving the corporation which has the effect
of increasing the proportionate share of the stock of any class or series of the
corporation beneficially owned by the interested stockholder; or (v) the receipt
by the interested stockholder of the benefit of any loans, advances, guarantees,
pledges or other financial benefits provided  by or through the corporation.  In
general,  Section 203 defines an interested stockholders as any entity or person
beneficially owning  15%  or  more  of  the  outstanding  voting  stock  of  the
corporation  and  any  entity  or  person  affiliated  with  or  controlling  or
controlled by such entity or person.

commencing  one year from the  date of this Prospectus.  In addition, holders of
the Representative's Warrants will have demand registration rights for a  period
of five years and piggyback registration rights for a period of seven years from
the  date of this  Prospectus with respect to  the Representative's Warrants and
the underlying shares of Common Stock. See 'Underwriting.'

                        SHARES ELIGIBLE FOR FUTURE SALE
 
GENERAL
 
     Upon the consummation of the Offering, the Company will have outstanding an
aggregate  of 3,625,000  shares of  Common Stock  (exclusive of  (i) the 300,000
shares of Common Stock reserved for issuance under the Option Plan, (ii)  50,000
shares  of Common  Stock reserved for  issuance under the  Director Option Plan,
(iii)  125,000  shares   of  Common   Stock  issuable  upon   exercise  of   the
Representative's Warrants and (iv) up to 187,500 shares of Common Stock issuable
upon  exercise of the Underwriters' over-allotment option). All of the 1,250,000
shares of Common  Stock sold in  the Offering will  be freely tradeable  without
restriction  under  the  Securities  Act  except  for  any  shares  purchased by
'affiliates' of  the  Company  (as  that  term  is  defined  in  the  rules  and
regulations  under the Securities Act). The remaining 2,375,000 shares of Common
Stock were issued by the Company in private transactions not involving a  public
offering,  are treated as 'restricted securities'  for purposes of Rule 144, and
may not be resold  unless they are  registered under the  Securities Act or  are
resold  pursuant  to an  exemption  from registration,  including  the exemption
provided under Rule 144 of the Securities Act.
 
     In general,  under Rule  144, as  currently in  effect, a  stockholder  (or
stockholders  whose shares  are aggregated)  who has  beneficially owned  for at
least two  years  shares  of  Common  Stock  that  are  treated  as  'restricted
securities,'  would be  entitled to  sell, within  any three-month  period, that
number of shares which does not exceed the greater of 1% of the then outstanding
shares of Common Stock or the average weekly trading volume in the Common  Stock
during  the four calendar weeks preceding the  date on which notice of such sale
is given. A  stockholder who  is not  deemed to have  been an  affiliate of  the
Company  at  any  time  during  the  90  days  preceding  a  sale,  and  who has
beneficially owned for  at least  three years shares  of Common  Stock that  are
treated  as 'restricted securities,' would be entitled to sell such shares under
Rule 144(k) immediately upon the effectiveness of the Offering without regard to
foregoing volume  limitations and  manner of  sale, notice  and availability  of
current  public information requirements. Sales or the expectation of sales of a
substantial number of shares of Common Stock in the public market following  the
Offering could adversely affect the prevailing market price of the Common Stock.
In  addition, the sale  of substantial amounts of  Common Stock acquired through
the exercise of the (i) options granted pursuant to the Option Plan or  Director
Option   Plan,  (ii)  Representative's  Warrants,  or  (iii)  the  Underwriters'
over-allotment option could  adversely affect prevailing  market prices for  the
Common  Stock. The Company and its officers, directors and existing stockholders
have agreed with the  Representative not to,  directly or indirectly,  register,
issue,  offer, sell,  offer to  sell, contract  to sell,  hypothecate, pledge or
otherwise dispose of any shares of Common Stock, (or any securities  convertible
into or exercisable or exchangeable for shares of Common Stock), for a period of
one  year from the date of this Prospectus, without the prior written consent of
the Representative, subject to certain exceptions.
 
     The Commission has recently proposed shortening the basic Rule 144  holding
period  from two  years to one  year; no  assurance can be  given as  to when or
whether such change will occur.
 
     In connection with  the Offering,  the Company has  agreed to  sell to  the
Representative the Representative's Warrants. See 'Underwriting.'
 
     On  or  about 18  months following  the consummation  of the  Offering, the
Company may file a Registration Statement  under the Securities Act to  register
an  aggregate of 300,000 shares of Common  Stock reserved for issuance under the
Option Plan and/or 50,000 shares of Common Stock reserved for issuance under the
Director Option Plan, thus permitting the resale of these shares of Common Stock
in the public market  without restriction under the  Securities Act, subject  to
the vesting requirements of the options pursuant to which these shares of Common
Stock  may be issued, the lock-up  agreements described above and the provisions
of the Option Plan or Director Option Plan. See 'Management.'

     The  Underwriters are  obligated to  purchase all  of the  shares of Common
Stock, if any are purchased.
 
     The Underwriters  for  whom  LT Lawrence  &  Co.,  Inc. is  acting  as  the
representative  ('Representative') have  advised the  Company that  they propose
initially to offer the  shares of Common  Stock to the public  on the terms  set
forth  on  the cover  page  of this  Prospectus.  The Underwriters  may  allow a
concession of not  more than  $        per share  to selected  dealers; and  the
Underwriters  may allow, and such dealers may  reallow, a concession of not more
than $       per share to certain other  dealers. After the consummation of  the
Offering,  the  consession  to selected  dealers  and the  reallowance  to other
dealers may  be changed  by the  Underwriters. The  shares of  Common Stock  are
offered  subject to  receipt and acceptance  by the Underwriters  and to certain
other conditions, including the right to reject orders in whole or in part.
 
     Upon the  consummation of  the  Offering, the  Company  will grant  to  the
Underwriters  an option  to purchase up  to 187,500 additional  shares of Common
Stock solely to cover over-allotments, if any. The option is exercisable for  45
days from the date of this Prospectus at the initial public offering price, less
the underwriting discount set forth on the cover page of this Prospectus. To the
extent  the  Representative  exercises  the  option,  the  Underwriters  will be
committed, subject to certain conditions, to purchase the additional shares.
 
   
     The Company has agreed to sell  to the Representative, for an aggregate  of
$125, Representative's Warrants to purchase 125,000 shares of Common Stock at an
exercise  price per share equal to 130% of the initial public offering price set
forth on the cover page of  this Prospectus. The Representative's Warrants  will
be  exercisable for a period of four years, commencing one year from the date of
this  Prospectus,  and  will  contain  anti-dilution  provisions  providing  for
appropriate  adjustment of the exercise  price and number of  shares that may be
purchased upon the occurrence of  certain events. The Representative's  Warrants
may  not be sold,  transferred or pledged until  one year from  the date of this
Prospectus, except that they  may be transferred,  in whole or  in part, at  any
time  to,  among  others, any  officer  of  the Representative.  Holders  of the
Representative's Warrant  have demand  and  piggyback registration  rights  with
respect  to  the Representative's  Warrants and  the underlying  securities. See
'Description of Capital Stock -- Registration Rights.'
    
 
     For a  period  of  five  years  from  the  date  of  this  Prospectus,  the
Representative will have the right to nominate one member to the Company's Board
of  Directors. Eric M. Chen, a managing  director of the Representative, will be
the  Representative's  initial   nominee  to   the  Board   of  Directors.   See
'Management -- Directors, Executive Officers and Key Personnel.'
 
     The  Company  and its  officers, directors  and existing  stockholders have
agreed with the Representative  not to directly  or indirectly register,  issue,
offer,  sell, offer to sell, contract  to sell, hypothecate, pledge or otherwise
dispose of any  shares of Common  Stock (or any  securities convertible into  or
exercisable or exchangeable for shares of Common Stock) for a period of one year
from the date

<PAGE>
of  this Prospectus,  without the prior  written consent  of the Representative,
subject to certain exceptions.
 
     Prior to  the Offering,  there has  been no  public market  for the  Common
Stock.  Consequently,  the  initial  public offering  price  will  be determined
through negotiations  between  the Company  and  the Representative.  Among  the
factors  considered  in  making  such determination  are  the  prevailing market
conditions,  the  Company's  financial  condition  and  operating  history,  the
operating history of Bioren and Bigmar Pharmaceuticals, the Company's prospects,
the  prospects for the  pharmaceutical and biotechnology  industries in general,
the management of the Company, the market prices of securities for companies  in
businesses similar to that of the Company and other factors deemed relevant.
 
     The  Company has agreed to pay the Representative a non-accountable expense
allowance equal to 2.5% of the gross proceeds of the Offering, of which none has
been paid as  of the date  of this Prospectus.  The Company has  also agreed  to
indemnify  the Underwriters  against, or  contribute to  losses arising  out of,
certain liabilities, including liabilities arising under the Securities Act.
 
     The Representative was organized in February  1992 and was registered as  a
broker-dealer   in  1993.  Prior  to   this  Offering,  the  Representative  has
participated as  a sole  or  co-manager in  three  public offerings.  See  'Risk
Factors -- Lack of Underwriting History.'
 
     The  Representative does not intend to  sell Common Stock from the Offering
to any discretionary accounts.

                         REPORT OF INDEPENDENT AUDITORS
 
Board of Directors and Stockholders
BIGMAR, INC.
 
     We  have audited  the accompanying  consolidated balance  sheets of Bigmar,
Inc., and subsidiaries as  at December 31,  1994 and December  31, 1995 and  the
related  consolidated statements of operations,  changes in stockholders' equity
and cash flows for each of the years in the three-year period ended December 31,
1995. These  financial  statements  are  the  responsibility  of  the  Company's
management.  Our  responsibility is  to express  an  opinion on  these financial
statements based on our audits.
 
     We conducted  our audits  in accordance  with generally  accepted  auditing
standards. Those standards require that we plan and perform the audits to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also  includes
assessing  the  accounting principles  used  and significant  estimates  made by
management, as well as evaluating the overall financial statement  presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In  our opinion, the financial  statements enumerated above present fairly,
in all material respects,  the consolidated financial  position of Bigmar,  Inc.
and  Subsidiaries,  as at  December  31, 1994  and  December 31,  1995,  and the
consolidated results of their  operations and their cash  flows for each of  the
years  in  the three-year  period ended  December 31,  1995, in  conformity with
generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
(NOTE 1) -- THE COMPANY:
 
     Bigmar,  Inc. (the 'Company')  was formed in  September 1995 by Chemholding
SA, Chemholding's principal stockholders and John G. Tramontana for the  purpose
of  manufacturing and distributing various oncological and biotechnical products
including six  oncological  products,  the distribution  rights  to  which  were
acquired  from affiliates of Chemholding SA. Certain stockholders of the Company
owned 100% of Bigmar Pharmaceuticals SA ('Pharmaceuticals') and 50% of Bioren SA
('Bioren'), two  Swiss  corporations.  The  other 50%  of  Bioren  is  owned  by
Pharmaceuticals.  On April 9, 1996 the  Company acquired 100% of Pharmaceuticals
and 50% of Bioren in a stock for  stock exchange. Since there was a high  degree
of  common ownership, the  acquisition was accounted for  as a reorganization of
companies under common  control. Accordingly,  the financial  statements of  the
Company   have  been   restated  to  include   the  results   of  operations  of
Pharmaceuticals for all periods presented and the results of Bioren from July 1,
1995, the  date that  Pharmaceuticals and  certain stockholders  of the  Company
acquired their interests.
 
     Pharmaceuticals  is engaged in the  distribution of oncological products in
various  countries  in  Europe  and  Bioren  is  primarily  a  manufacturer  and
distributor  of intravenous infusion solutions  in Switzerland. In addition, the
Company intends to  become a  manufacturer and a  distributor of  pharmaceutical
products and under the four collaborative agreements described in Note 11.
 
     The Company intends to have an initial public offering of its common stock.
In  connection therewith, the Company expects  to incur significant costs which,
if the offering is not consummated, will be charged to expense.
 
   
     In April, 1996  the stockholders of  the Company contributed  99% of  their
shares to the Company. Also in April, 1996, the Company restated and amended its
certificate  of incorporation, increasing its  authorized shares of common stock
from 10,000,000 to 15,000,000, authorizing 5,000,000 shares of preferred  stock,
and  effecting a  2.105263 for one  reverse stock split.  These transactions are
reflected retroactively in the accompanying financial statements.
    
 
(NOTE 2) -- BIOREN ACQUISITION:
 
     On June 30, 1995, Pharmaceuticals acquired 100% of the outstanding stock of
Bioren for  $5,195,000  and  immediately  sold  50%  of  the  stock  to  certain
stockholders of Pharmaceuticals and the Company.
 
     The  consolidated financial statements include  the accounts of Bioren from
July 1,  1995, the  date of  acquisition  from a  nonaffiliated party.  Had  the
acquisition  of Bioren occurred at the  beginning of 1994, the Company's results
would have been as follows:

(NOTE 3) -- SIGNIFICANT ACCOUNTING POLICIES:
 
BASIS OF PREPARATION:
 
     The consolidated financial statements include the accounts of Bigmar,  Inc.
and   its  wholly   owned  subsidiaries,  Pharmaceuticals,   Bioren  and  Bigmar
Therapeutics, Inc. ('Therapeutics'), a Delaware corporation formed in  September
1995   to   enter   into   a   partnership   agreement   (see   Note   11).  All

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
significant intercompany accounts and transactions  have been eliminated in  the
consolidated financial statements.
 
     The  preparation  of  financial  statements  in  conformity  with generally
accepted  accounting  principles  requires  management  to  make  estimates  and
assumptions  that afffect the reported amounts  of assets and liabilities at the
date of  the financial  statements  and the  reported  amounts of  revenues  and
expenses  during the  reporting period. Actual  results could  differ from those
estimates.
 
FAIR VALUE OF FINANCIAL INSTRUMENTS:
 
     The  carrying  value  of  cash,   trade  receivables  and  trade   payables
approximates the fair value because of the short maturity of those instruments.
 
     For  long-term debt, the carrying value approximates the fair value because
no major changes have occurred in the applicable interest rates.
 
INVENTORY:
 
     Inventory is stated  at the  lower of cost  or market  using the  first-in,
first-out (FIFO) method.
 
PROPERTY, PLANT AND EQUIPMENT:
 
     Property,  plant and equipment are stated  at cost. Maintenance and repairs
are  charged  to  operations  as  incurred.  Depreciation  is  calculated  on  a
straight-line  basis utilizing  the assets'  estimated useful  lives of  3 to 25
years.
 
ORGANIZATION EXPENSES:
 
     Costs associated with the organization  of the Company are capitalized  and
amortized over five years.
 
GOODWILL:
 
     Goodwill  is  amortized over  a  10 year  period.  The Companies  intend to
evaluate the continuing value of goodwill based on undiscounted cash flows.
 
INCOME TAXES:
 
     Income taxes are  accounted for by  the asset/liability approach.  Deferred
taxes  arise from differences  between the financial reporting  and tax bases of
assets and liabilities.
 
FOREIGN CURRENCY TRANSACTIONS:
 
     Gains and losses resulting from  foreign currency transactions and  changes
in  foreign currency positions are included in income or expense currently. Such
amounts were insignificant in 1995, 1994, and 1993.
 
FOREIGN CURRENCY TRANSLATION:
 
     The Company's operations  are located  in Switzerland and  its net  assets,
revenues  and expenses are substantially all  denominated in Swiss francs, while
the Company presents its consolidated financial statements in US dollars. Assets
and liabilities are translated  at the exchange rates  in effect at the  balance
sheet  date.  Revenues  and  expenses are  translated  at  the  weighted average
exchange rates for the period. Net gains and losses arising upon translation  of
local  currency financial statements to US dollars are accumulated in a separate
component of stockholders' equity, the cumulative translation

adjustment account, which may be realized  upon the eventual disposition by  the
Company of part or all of its investments in its Swiss operations.
 
PER SHARE DATA:
 
     Net  income (loss)  per share  is based on  the weighted  average number of
shares outstanding during  each period  after giving retroactive  effect to  the
reorganization,  the  capital  contribution  and the  reverse  stock  split, all
described in Note 1.

     The  Swiss  Federal Code  of  Obligation provides  that  at least  5%  of a

addition, 10%  of any  distribution in  excess of  a 5%  dividend also  must  be
appropriated  to the legal reserve.  The legal reserve of up  to 5% of the share
capital is not available for distribution.
 
(NOTE 10) -- INCOME TAXES:
 
     Deferred income  tax  assets and  liabilities  are provided  for  temporary
differences  between  financial  statement  amounts  and  the  amounts currently
taxable in the jurisdictions in which the Companies operate. Deferred taxes  are
provided principally in relation to operating loss carryforwards of Bioren which
can  only be utilized to offset future taxable  income, if any, of Bioren for up
to six  years  after incurring  the  losses,  depending on  the  applicable  tax
legislation. The deferred tax asset at December 31, 1995 has been fully reserved
as the future utilization of such asset is uncertain.
 
     The  deferred tax asset as of December 31,  1995 and March 31, 1996, was as
follows:

     The tax charge in Switzerland  is an accumulation of  the taxes due to  the
city,  the canton (state) and the federal authorities. Therefore, the tax burden
varies from one entity to another depending upon its location. While the  actual
tax rate is a function of the percentage of profitability in relation to taxable
equity,  the  Companies  believe  that  20% is  a  fair  approximation  of their
effective cumulative tax  rates. In addition,  as Swiss tax  laws do not  permit
consolidated  tax  filings, possible  tax  losses in  one  entity do  not offset
taxable income in another.
 
     On January 1, 1995, a  new federal tax law, and  for most Swiss cantons,  a
new cantonal tax law, came into force in Switzerland. The new laws provide for a
change  in the system of assessment from  a two-year past assessment period to a
one-year current  assessment period.  Because  these changes  may create  a  gap
during which certain profits made in prior years may not be taxed or may be only
partially taxed, the new laws have provided for a transition period during which
a special method is followed to calculate income taxes. Since the 1995 taxes due
based  on the old methods  of assessment had been  fully accrued for during 1993
and 1994, the 1995 tax charge only relates to the adjustment needed based on the
1995 income.
 
     A reconciliation between  the actual  income tax expense  and income  taxes
computed  by  applying the  United  States Federal  income  tax rate  of  34% to
earnings before taxes is as follows:

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
(NOTE 11) -- COLLABORATIVE AGREEMENTS WITH RELATED PARTIES:
 
(A) THE CERNELLE AGREEMENT:
 
     On November 5, 1995 Pharmaceuticals entered into an exclusive  distribution
and  supply  agreement  ('Cernelle  Agreement')  with  AB  Cernelle,  a  Swedish
corporation owned  by  a  principal  stockholder  of  Bigmar  ('Cernelle').  The
Cernelle   Agreement  provides  that  Pharmaceuticals  shall  be  the  exclusive
worldwide  distributor  of  certain  oral  dosage  cancer  products   ('Cernelle
Products')  and is for a term of 15  years from the date of the first commercial
sale by Pharmaceuticals of the  Cernelle Products. Pharmaceuticals shall pay  to
Cernelle  a one-time amount  of $100,000 upon notification  by Cernelle that the
Cernelle Products are ready for  shipment to Pharmaceuticals and shall  purchase
the  Cernelle Products  at certain  prices as defined  in the  agreement. In the
event the term of the Cernelle Agreement or any renewal thereof is not extended,
Pharmaceuticals shall  have, at  a minimum,  a nonexclusive  worldwide right  to
distribute the Cernelle Products for three additional years.
 
     Pharmaceuticals  also entered  into a  technical services  agreement, dated
November 5, 1995, with Cernelle ('Cernelle TSA'). The Cernelle TSA provides that
Cernelle will prepare abbreviated new drug applications ('ANDA') submissions  to
the  United States  Food and Drug  Administration ('FDA')  covering the Cernelle
Products. Pharmaceuticals shall  pay Cernelle  a fee  of $20,000  for each  ANDA
submitted  to  and  accepted  by  Pharmaceuticals.  Pursuant  to  the agreement,
Cernelle assigned to  Pharmaceuticals the  sole and exclusive  right, title  and
interest  in and  to the technical  services without  further consideration. The
term of this agreement is  for 15 years and is  renewable on the mutual  written
agreement of the parties.
 
(B) THE BIOFERMENT AGREEMENT:
 
     Pharmaceuticals  entered into a license and supply agreement dated November
14, 1995, with  Bioferment, a division  of Cerbios Pharma,  a Swiss  corporation
owned  by  a  principal  stockholder of  Bigmar  ('Bioferment'),  which develops
pharmaceutical products. Subject to the payment of the license fees and  subject
to  a contingent  license to  manufacture and  a security  agreement, Bioferment
grants to Pharmaceuticals  an exclusive paid-up  license to make,  use and  sell
certain Bioferment products worldwide.
 
     Pursuant  to  the  agreement  Pharmaceuticals  shall  pay  to  Bioferment a
$500,000 license  fee,  all of  which  is  nonrefundable and  shall  be  payable
$100,000  on July  1, 1996,  and four further  $100,000 payments  as certain FDA
filing and  approval milestones  are  met. The  license  fee shall  be  credited
against future royalty obligations due to Bioferment from Pharmaceuticals.
 
     The  agreement will terminate fifteen years after the first commercial sale
of the last Bioferment product introduced by Pharmaceuticals, its affiliates  or
sublicensees.
 
     On  December 14, 1995, Pharmaceuticals  and Bioferment entered into another
agreement  for  the  worldwide  exclusive  distribution  by  Pharmaceuticals  of
products  derived  from certain  other  Bioferment technologies.  This agreement
requires a  one-time  payment  by Pharmaceuticals  of  $100,000  and  terminates
fifteen  years from the date of the  first commercial sale by Pharmaceuticals of
the products.
 
(C) THE SAPEC AGREEMENT:
 
     Bioren entered into an exclusive  distribution and supply agreement,  dated
November  14, 1995, with Sapec, a division of Cerbios Pharma, a company owned by
a principal stockholder of Bigmar  ('Sapec Agreement'). Sapec is a  manufacturer
of  pharmaceutical products for  commercial distribution. Pursuant  to the Sapec
Agreement, Bioren was appointed Sapec's exclusive worldwide distributor, subject
to certain  exceptions, of  products  developed by  Sapec. The  Sapec  Agreement
provides  that  Bioren  obtain any  private  or public  regulatory  or licensing
approval necessary for Bioren or its designee to import, distribute and sell the
Sapec Products in  any country throughout  the world. Bioren  shall pay Sapec  a
one-time  fee for the grant of such  exclusive rights and licenses in the amount
of $100,000, which

is payable upon  notification by  Sapec that the  Sapec Products  are ready  for
initial  shipment to Bioren. The pricing for  the Sapec Products is set forth in
the Sapec Agreement.
 
     The Sapec Agreement  shall continue for  a term of  fifteen years from  the
date  of first commercial sale  by Bioren of Sapec  Products and is renewable as
mutually agreed upon.
 
(D) THE PROTYDE AGREEMENTS:
 
     Pursuant to an agreement dated as of October 1995 Therapeutics and a wholly
owned subsidiary  of  Protyde Pharmaceuticals,  Inc.  'Protyde', have  formed  a
partnership,  Protyde-Bigmar  Therapeutics ('Partnership'),  for the  purpose of
coordinating the manufacture  and marketing of  certain pharmaceutical  products
('products'), for the treatment of human cancer.
 
     The business of the Partnership is to obtain FDA approval to market certain
products,  to manufacture the products, and  to market the products. Pursuant to
the Partnership Agreement, each of the partners initially has a 50% interest  in
the  Partnership. The Company will account for its investment in the Partnership
on the equity method.  As its initial contribution  to the Partnership,  Protyde
will  contribute to the Partnership up to $3,075,000 in cash, the first $750,000
of which was  paid to  the Company on  March 29,  1996, with the  balance to  be
contributed at such times and in such amounts so as to enable the Partnership to
timely  satisfy its obligations, and to make its payments under the terms of its
manufacturing  agreement.   As  Therapeutics'   capital  contribution   to   the
Partnership,  Therapeutics  will cause  the  Company to  make  its manufacturing
capacity available  to the  Partnership  under the  terms of  the  manufacturing
agreement.
 
     Under  the Partnership Agreement, the Partnership  is the sole owner of all
right, title and interest in all  FDA-approved ANDAs for any products  submitted
for  approval by the Partnership. The Partnership  is also the sole owner of all
right, title  and  interest in  and  to proprietary  information  and  marketing
information which is developed or acquired by a partner or its affiliates, using
partnership  funds, or while  performing activities subject  to reimbursement by
the Partnership.  However,  during the  term  of  the Partnership  each  of  the
partners  has  a royalty-free,  worldwide  right to  use  and practice  any such
proprietary information and  marketing information for  any purpose outside  the
scope of the Partnership's business.
 
     Pursuant  to the Partnership Agreement, the Partnership will continue until
December 31, 2005, unless earlier terminated.
 
     The Company has entered into a manufacturing agreement with the Partnership
and Protyde  has  entered  into  a marketing  agreement  with  the  Partnership.
Pursuant  to the manufacturing agreement, the Company's responsibilities include
(i) acquiring  and  performing  stability  testing  on  all  raw  materials  and
packaging  materials  necessary  for  the  manufacture  of  the  products,  (ii)
providing production  capacity available  to the  Partnership in  order to  meet
production  obligations, and (iii) undertaking  all measures for quality control
which are either required by the FDA or requested by the Partnership.
 
(NOTE 12) -- COMMITMENTS:
 
EMPLOYMENT AGREEMENT:
 
     In April 1996  the Company entered  into a five  year employment  agreement
with its President and Chief Executive Officer providing for an annual salary of
$200,000, commencing upon consummation of the initial public offering subject to
increases  based on the consumer price index, and bonuses of at least 25% of the
base salary.
 
     The Company also intends to enter into a two-year employment agreement with
its Vice President and Chief Financial Officer providing for an annual salary of
$80,000 subject to an annual review and bonuses of 15% of the base salary.

LEASES:
 
     In March, 1996 the Company entered into an agreement to sublease  executive
office  space from a  company of which  the Company's President  was formerly an
officer. The  sublease is  for a  term of  two years  and provides  for rent  of
$22,315 per annum.
 
     Bioren  sub-leases part of its  Couvet facility pursuant to  a year to year
lease. The rental income from  July 1, 1995 (date  of acquisition of Bioren)  to
December  31, 1995 and for the three months ended March 31, 1996 was $49,144 and
$24,095, respectively.
 
(NOTE 13) -- CONCENTRATION OF CREDIT RISK:
 
     Bioren's main customers for intravenous  products are hospitals located  in
Switzerland.  A significant  number of these  hospitals are owned  by the canton
(state) or the city where they are located and the credit risk traditionally  is
not  significant. For other pharmaceutical products, the customers are privately
owned and credit risk  is greater. The management  has recorded its estimate  of
credit loss through the allowance for doubtful accounts.
 
(NOTE 14) -- SIGNIFICANT CUSTOMERS:
 
     Sales to significant customers were as follows:

Bioren  SA for the six months  ended June 30, 1995 and  for each of the years in
the two-year period ended December 31, 1994. These financial statements are  the
responsibility  of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audits.
 
     We conducted  our audits  in accordance  with generally  accepted  auditing
standards. Those standards require that we plan and perform the audits to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also  includes
assessing  the  accounting principles  used  and significant  estimates  made by
management, as well as evaluating the overall financial statement  presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In  our opinion, the financial  statements enumerated above present fairly,
in all material respects, the results of operations and cash flows of Bioren  SA
for the six months ended June 30, 1995 and for each of the years in the two-year

                         NOTES TO FINANCIAL STATEMENTS
 
(NOTE 1) -- NATURE OF BUSINESS:
 
     Bioren  SA ('Company') manufactures intravenous and pharmaceutical products
for the Swiss and foreign markets.
 
     Bigmar  Pharmaceuticals  SA  ('Pharmaceuticals')   acquired  100%  of   the
outstanding stock of the Company on June 30, 1995 for $5,195,000 and immediately
sold   50%  of  the  stock  to   certain  shareholders  of  Pharmaceuticals  and
shareholders of Bigmar, Inc., a Delaware corporation for $2,597,500.
 
(NOTE 2) -- SIGNIFICANT ACCOUNTING POLICIES:
 
INVENTORY:
 
     Inventories are stated at the lower  of cost or market using the  first-in,
first-out  (FIFO)  method. Provisions  for obsolete  items  are recorded  to the
extent considered necessary by the Company.
 
PROPERTY, PLANT AND EQUIPMENT:
 
     Property, plant and equipment are carried at cost. Maintenance and  repairs
are  charged to operations. Depreciation is  calculated on a straight-line basis
utilizing the assets' estimated useful lives of 3 to 25 years.
 
INCOME TAXES:
 
     Income taxes are  accounted for by  the asset/liability approach.  Deferred
taxes  arise from differences  between the financial reporting  and tax bases of
assets and liabilities.
 
FOREIGN CURRENCY TRANSACTIONS
 
     Gains and losses resulting from  foreign currency transactions and  changes
in  foreign currency positions are included in income or expense currently. Such
amounts were insignificant for the six months  ended June 30, 1995 and for  each
of the years in the two year period ended December 31, 1994.
 
FOREIGN CURRENCY TRANSLATION
 
     The  Company's operations  are located in  Switzerland and  its net assets,
revenues and expenses are substantially  all denominated in Swiss francs,  while
the Company presents its consolidated financial statements in US dollars. Assets
and  liabilities are translated at  the exchange rates in  effect at the balance
sheet date.  Revenues  and  expenses  are translated  at  the  weighted  average
exchange  rates for the period. Net gains and losses arising upon translation of
local currency financial statements to US dollars are accumulated in a  separate
component   of  Stockholders'  Equity,  the  Cumulative  Translation  Adjustment
account, which may be realized upon  the eventual disposition by the Company  of
part or all of its investments in its Swiss operations.
 
(NOTE 3) -- INCOME TAXES:
 
     The  tax charge in Switzerland  is an accumulation of  the taxes due to the
city, the canton (state) and the federal authorities. Therefore, the tax  burden
varies  from one entity to another depending upon its location. While the actual
tax rate is a function of the percentage of profitability in relation to taxable
equity, the Company believes that 20%  is a fair approximation of its  effective
cumulative tax rate.
 
     On  January 1, 1995, a  new federal tax law, and  for most Swiss cantons, a
new cantonal tax law, came into force in Switzerland. The new laws provide for a
change in the system of assessment from  a two year past assessment period to  a
one  year  current assessment  period. Because  these changes  may create  a gap
during which certain profits made in prior years may not be taxed or may be only
partially

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
taxed, the new laws have provided for a transition period during which a special
method is followed to calculate income taxes. Since the 1995 taxes due based  on
the  old methods of assessment had been  fully accrued for during 1993 and 1994,
the 1995 tax  charge only relates  to the  adjustment needed based  on the  1995
income.
 
     There  is no  tax expense  in 1995  due to  the reduction  of the valuation
allowance on the Company's deferred tax asset, resulting from the utilization of
the Company's operating loss carryforwards, offsetting the provision for  income
taxes.
 
(NOTE 4) -- LEASE:
 
     The Company leases part of its Couvet facility. The rental income for 1995,
1994 and 1993 was $49,144 (six months), $84,477 and $84,704, respectively.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
     Under  Section 145  of the Delaware  General Corporation  Law ('DGCL'), the
Registrant has  broad powers  to  indemnify its  directors, officers  and  other
employees.  This  section (i)  provides that  the statutory  indemnification and
advancement of expenses provisions of the DGCL are not exclusive, provided  that
no  indemnification may be made to or on  behalf of any director or officer if a
judgment or  other  final  adjudication  adverse  to  the  director  or  officer
establishes  that his  acts were committed  in bad  faith or were  the result of
active and deliberate  dishonesty and were  material to the  cause of action  so
adjudicated,  or that he personally  gained in fact a  financial profit or other
advantage to which he was not legally entitled, (ii) establishes procedures  for
indemnification  and  advancement  of  expenses that  may  be  contained  in the
certificate of incorporation or  by-laws, or, when authorized  by either of  the
foregoing,  set forth  in a  resolution of the  stockholders or  directors or an
agreement providing  for  indemnification  and advancement  of  expenses,  (iii)
applies  a  single standard  for statutory  indemnification for  third-party and
derivative suits by providing that indemnification is available if the  director
or officer acted in good faith, for a purpose which he reasonably believed to be
in  the best  interests of  the corporation,  and, in  criminal actions,  had no
reasonable cause to believe that his conduct was unlawful, and (iv) permits  the
advancement  of litigation expenses upon receipt of an undertaking to repay such
advance if the director or officer  is ultimately determined not to be  entitled
to   indemnification  or  to  the  extent   the  expenses  advanced  exceed  the
indemnification to which the director or officer is entitled. Section 145(g) the
DGCL permits  the  purchase of  insurance  to  indemnify a  corporation  or  its
officers and directors to the extent permitted.
 
     As  permitted  by  Section 145(e)  of  the DGCL,  the  Registrant's By-laws
provide that the Registrant shall indemnify its officers and directors, as such,
to the fullest extent permitted by applicable law, and that expenses  reasonably
incurred  by any  such officer  or director in  connection with  a threatened or
actual action or  proceeding shall  be advanced  or promptly  reimbursed by  the
Registrant in advance of the final disposition of such action or proceeding upon
receipt  of an undertaking by or on behalf  of such officer or director to repay
such amount if  and to the  extent that  it is ultimately  determined that  such
officer or director is not entitled to indemnification.
 
     Article  Sixth  of the  Registrant's  Restated and  Amended  Certificate of
Incorporation provides that no  director of the  Registrant shall be  personally
liable  to the Registrant or its  stockholders for monetary damages for breaches
of fiduciary duty as a director, except for liability (i) for any breach of  the
director's  duty of loyalty to the Registrant or its stockholders, (ii) for acts
or omissions not  in good  faith or which  involve intentional  misconduct or  a
knowing  violation of law, (iii) under Section 174  of the DGCL, or (iv) for any
transaction from which the director derived an improper personal benefit.

ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES.
 
     Set forth below  is information  as to  securities of  the Registrant  sold
within  the past three years which were not registered under the Securities Act.
The issuance of all such securities were made in reliance upon an exemption from
the registration  provisions of  the  Securities Act  afforded by  Section  4(2)
thereof,  as  transactions by  an issuer  not involving  a public  offering. The
Registrant will place stop  transfer instructions with  its transfer agent  with
respect  to all  such securities.  No underwriters were  involved in  any of the
sales so there were no underwriting discounts or commissions.

ITEM 17. UNDERTAKINGS.
 
     The undersigned Registrant hereby undertakes the following:
 
          (a)(1)  To file, during any period in  which offers or sales are being
     made, a post-effective amendment to this Registration Statement;
 
             (i) To include any prospectus  required by Section 10(a)(3) of  the
        Securities Act;
 
             (ii) To reflect in the Prospectus any facts or events arising after
        the  effective date  of the Registration  Statement (or  the most recent
        post-effective  amendment  thereof)  which,   individually  or  in   the
        aggregate,  represents a fundamental change in the information set forth
        in the Registration Statement; and
 
                                      II-4
 <PAGE>
<PAGE>
             (iii) To include any material information with respect to the  plan
        of  distribution not previously disclosed  in the Registration Statement
        or  any  material  change  to  such  information  in  the   Registration
        Statement;
 
             (2)  That, for the  purpose of determining  any liability under the
     Securities Act, each such post-effective amendment shall be deemed to be  a
     new  registration statement relating to the securities offered therein, and
     the offering of  such securities at  that time  shall be deemed  to be  the
     initial bona fide offering thereof.
 
             (3)  To  remove  from  registration by  means  of  a post-effective
     amendment any of the securities being registered which remain unsold at the
     termination of the Offering.
 
          (b) To provide  to the Underwriters  at the closing  specified in  the
     Underwriting  Agreement, certificates in  such denominations and registered
     in such names as required by the Underwriters to permit prompt delivery  to
     each purchaser.
 
          (c)  Insofar  as  indemnification for  liabilities  arising  under the
     Securities Act  may be  permitted to  directors, officers  and  controlling
     persons  of  the  Registrant  pursuant  to  the  foregoing  provisions,  or
     otherwise, the  Registrant has  been advised  that in  the opinion  of  the
     Commission  such indemnification is  against public policy  as expressed in
     the Securities Act and  is, therefore, unenforceable. In  the event that  a
     claim  for indemnification against such liabilities (other than the payment
     by the Registrant of expenses incurred  or paid by a director, officer,  or
     controlling  person  of the  Registrant in  the  successful defense  of any
     action, suit  or  proceeding) is  asserted  by such  director,  officer  or
     controlling  person in connection with the securities being registered, the
     Registrant will, unless in the opinion  of its counsel the matter has  been
     settled  by  controlling  precedent,  submit  to  a  court  of  appropriate
     jurisdiction the question  whether such  indemnification by  it is  against
     public  policy as expressed in  the Securities Act and  will be governed by
     the final adjudication of such issue.
 
          (d)(1) For purposes of determining any liability under the  Securities
     Act,  the information omitted from the form  of prospectus filed as part of
     this Registration Statement in reliance upon  Rule 430A and contained in  a
     form  of prospectus filed  by the Registrant pursuant  to Rule 424(b)(1) or
     (4) or 497(h) under the Securities Act  shall be deemed to be part of  this
     Registration Statement as of the time it was declared effective.
 
             (2)  For  the  purpose  of  determining  any  liability  under  the
     Securities Act,  each  post-effective amendment  that  contains a  form  of
     prospectus  shall be deemed to be  a new registration statement relating to
     the securities offered herein, and the offering of such securities at  that
     time shall be deemed to be the initial bona fide offering thereof.

               (e) Whether or not the shares of that series shall be redeemable,

        upon the payment of dividends or the making of other  distributions  on,

        or any subsidiary of, any outstanding stock of the Corporation;

               (h) The  rights of the  shares  of that  series in the event of a
        voluntary or involuntary liquidation, dissolution or

<PAGE>
<PAGE>

        preference to, or in another  relation to, the comparable  rights of any
        other class or classes or series of capital stock; and

               (i) Any other relative, participating,  optional or other special
        rights, qualifications, limitations or restrictions of that series.

               (b)    Common Stock.

               1.  Dividends  may be paid  upon  the  Common  Stock  as and when
declared by the Board of Directors out of any funds legally available therefor.

               2.  Upon  any  liquidation,  dissolution  or  winding  up of  the
Corporation,  the  holders of the Common  Stock shall be entitled to receive any
and all assets of the Corporation remaining to be paid or distributed.

               3.  Except as  otherwise  provided  by statute or by any  express
provision of this Certificate,  all rights to vote and all voting power shall be
exclusively vested in the Common Stock and the holders thereof shall be entitled
to one vote for each share of Common  Stock for the  election of  directors  and
upon all other matters.

               (c) All Stock.  The  Corporation  shall be  entitled to treat the
person in whose  name any  share,  right or option  is  registered  as the owner
thereof, for all purposes,  and shall not be bound to recognize any equitable or
other claim to or  interest  in such  share,  right or option on the part of any
other person,  whether or not the Corporation shall have notice thereof, save as
may be expressly provided by the laws of the State of Delaware.

               (d) Stock  Split.  Effective at the close of business on the date
that this Restated and Amended  Certificate of  Incorporation  is filed with the
Secretary of State of the State of Delaware,  and without  further action on the
part  of  the  Corporation  or  the  holders  of its  outstanding  common  stock
immediately prior thereto (the "Outstanding Common"),  each share of Outstanding
Common  shall be  automatically  converted  into the  quotient  of 1 divided  by
2.105263  shares  of  Common  Stock.  No  fractional  shares  shall be issued in
connection with the foregoing reclassification and, in lieu thereof, the Company
shall round all shares of Common Stock to the nearest whole number. Effective at
the close of  business on such date,  each  certificate  representing  shares of
Outstanding  Common  shall be deemed to  represent  the quotient of 1 divided by
2.105263  shares of Common Stock.  As promptly as  practicable  thereafter,  the
Corporation,  upon delivery and surrender of existing certificates  representing
shares of the Outstanding Common By the holders thereof, which certificates,  if
the Board of Directors of the Corporation so requests, shall be duly endorsed to
the Corporation in blank or accompanied by proper instruments of transfer to the
Corporation (such endorsements or instruments of transfer to be


<PAGE>
<PAGE>


in form satisfactory to the Corporation), shall issue and deliver or cause to be
delivered to each such holder a certificate  or  certificates  representing  the
quotient of 1 divided by 2.105263  shares of Common Stock.  No dividend or other
distributions,  if any,  that are declared by the Board of  Directors  after the
close of  business  on the  aforementioned  date of filing  with  respect to the
Common  Stock  shall be paid to the  holders of  Outstanding  Common  until such
holders shall have delivered and  surrendered  their  certificates  representing
shares of Outstanding Common pursuant to this paragraph.

               FIFTH: (a) The number of directors of the Corporation which shall
constitute the whole Board of Directors of the Corporation shall be such as from
time to time may be fixed by or in the manner provided in the By-laws, but in no
case shall the number of directors be less than one.  Except as may otherwise be
required by law,  vacancies  in the Board of Directors  of the  Corporation  and
newly created directorships resulting from any increase in the authorized number
of directors may be filled by a majority of the directors then in office, though
less than a quorum, or by a sole remaining director.

                      (b) All  corporate  powers  of the  Corporation  shall  be
exercised by the Board of Directors  except as otherwise  provided  herein or by
law. In furtherance of the powers  conferred by statute and by law, the Board of
Directors shall have the power to adopt,  alter,  amend or repeal the By-laws of
the  Corporation,   without  any  action  on  the  part  of  the   Corporation's
stockholders.

               SIXTH:  A director  of the  Corporation  shall not be  personally
liable to the Corporation or its  stockholders for monetary damages for breaches
of fiduciary duty as a director,  except for liability (i) for any breach of the
director's duty of loyalty to the Corporation or its stockholders, (ii) for acts
or omissions  not in good faith or which  involve  intentional  misconduct  or a
knowing  violation of law,  (iii) under  Section 174 of the General  Corporation
Law, or (iv) for any  transaction  from which the  director  derived an improper
personal benefit; it being the intention of the foregoing provision to eliminate
the liability of the Corporation's  directors to the fullest extent  permitted
by Section  102(b)(7)  of the General  Corporation  Law, as amended from time to
time.


               SEVENTH:  The Corporation shall indemnify and advance expenses to
the fullest extend  permitted by Section 145 of the General  Corporation Law, as
amended  from time to time,  each  person who is or was a director or officer of
the Corporation and the heirs,  executors and administrators of such person. Any
expenses  (including  attorneys'  fees)  incurred by each person who is or was a
director  or  officer  of  the  Corporation,   and  the  heirs,   executors  and
administrators  of such person, in connection with defending any such proceeding
in advance of its final disposition shall be paid by the Corporation;  provided,
however,  that if the  General  Corporation  Law  requires,  an  advancement  of
expenses incurred by an indemnitee in his capacity as a director or officer (and
not in any

<PAGE>
<PAGE>


other  capacity  in  which  service  was  or is  rendered  by  such  indemnitee,
including,  without  limitation,  service to an employee  benefit plan) shall be
made only upon delivery to the  Corporation of an undertaking by or on behalf of
such  indemnitee  to repay all amounts so advanced,  if it shall  ultimately  be
determined  that such  indemnitee  is not  entitled to be  indemnified  for such
expenses under this Article or otherwise.

               EIGHTH:  Whenever a compromise or arrangement is proposed between
this  Corporation  and its  creditors  or any class of them and/or  between this
Corporation  and its  stockholders  or any class of them, any court of equitable
jurisdiction  within the State of Delaware may, on the  application in a summary
way of this  Corporation  or of any creditor or stockholder  thereof,  or on the
application of any receiver or receivers  appointed for this  Corporation  under
the  provisions  of  Section  291 of  Title  8 of the  Delaware  Code  or on the
application of trustees in dissolution or of any receiver or receivers appointed
for this  Corporation  under the  provisions  of  Section  279 of Title 8 of the
Delaware Code, order a meeting of the creditors or class of creditors, and/or of
the stockholders or class of stockholders of this  Corporation,  as the case may
be, to be summoned in such  manner as the said court  directs.  If a majority in
number  representing  three-fourths  in  value  of the  creditors  or  class  of
creditors,  and/or  of  the  stockholders  or  class  of  stockholders  of  this
Corporation,  as the case may be, agree to any compromise or arrangement  and to
any  reorganization  of this  Corporation as  consequence of such  compromise or
arrangement,  the said  compromise or  arrangement  and the said  reorganization
shall,  if sanctioned by the court to which the said  application has been made,
be  binding  on all the  creditors  or class  of  creditors,  and/or  on all the
stockholders or class of stockholders,  of this Corporation, as the case may be,
and also on this Corporation.

               NINTH: Meetings of stockholders may be held within or without the
State of Delaware,  as the By-Laws may provide. The books of the Corporation may
be kept (subject to any provision  contained in the statutes)  outside the State
of  Delaware at such place or places as may be  designated  from time to time by
the Board of  Directors  or in the  By-Laws  of the  Corporation.  Elections  of
Directors  need not be by written  ballot unless the By-Laws of the  Corporation
shall so provide.

               TENTH: The Corporation reserves the right to amend, alter, change
or repeal any provision  contained in this Restated and Amended  Certificate  of
Incorporation  in the manner now or hereafter  prescribed by law, and all rights
and power conferred herein upon directors, stockholders and officers are granted
subject to this reserved power.

               ELEVENTH:  The Board of Directors is authorized  to make,  alter,
amend,  change,  add to or repeal the  Corporation's  by-laws at any  regular or
special meeting of the Board of Directors.

                                       OF
                             THE BOARD OF DIRECTORS
                                       OF
                                  BIGMAR, INC.


                  The undersigned, being all of the members of the Board of
Directors of Bigmar, Inc., a Delaware corporation (the "Corporation"), pursuant
to Section 141(f), of the Delaware General Corporation Law and Article III,
Section 15, of the By-laws of the Corporation, do hereby consent to the adoption
of and do hereby adopt the following resolutions:

                  RESOLVED, that, in accordance with Article VIII of the By-Laws
         of the Corporation, this Board of Directors deems it advisable that the
         By-Laws of the Corporation be amended so as to provide for the issuance
         of uncertificated shares in accordance with Section 158 of the Delaware
         General Corporation Law, and for such purpose, to restate Article V,
         Section 1 thereof, to read as follows:

                  "SECTION 1. Stock Certificates. Every holder of stock in the
                  Corporation shall be entitled to have a certificate, signed
                  by, or in the name of the Corporation by, the Chairman of the

                  Treasurer or an Assistant Treasurer or the Secretary or an
                  Assistant Secretary of the Corporation, certifying the number
                  of shares owned by him in the Corporation, provided, however,
                  that upon resolution of the Board, the Corporation may issue
                  uncertificated shares. If the Corporation shall be authorized
                  to issue more than one class of stock or more than one series
                  of any class, the designations, preferences and relative,
                  participating, optional or other special rights of each class
                  of stock or series thereof and the qualifications, limitations
                  or restriction of such preferences and/or rights shall be set
                  forth in full or summarized on the face or back of the
                  certificate which the Corporation shall issue to represent
                  such class or series of stock, provided that, except as
                  otherwise provided in Section 202 of the General Corporation
                  Law of the State of Delaware, in lieu of the foregoing
                  requirements, there may be set forth on the face or back of
                  the certificate which the Corporation shall issue to represent
                  such class or series of stock, a statement that the
                  Corporation will

                  furnish without charge to each stockholder who so requests the
                  designations, preferences and relative, participating,
                  optional or other special rights of each class of stock or
                  series thereof and the qualifications, limitations or
                  restrictions of such preferences and/or rights."

         ; and be it further

                  RESOLVED, that, in accordance with Article VIII of the By-Laws
         of the Corporation, this Board of Directors deems it advisable that the
         By-Laws of the Corporation be amended so as to provide that the holders
         of at least 10% of the outstanding stock  entitled to vote at special
         meetings be entitled to call such meetings, and for these purposes, to
         restate Article II, Section 2 thereof to read as follows:

                  "SECTION 3. Special Meeting. Special meetings of
                  stockholders, unless otherwise prescribed by statute,
                  may be called at any time by the Board of Directors, by
                  the Chairman of the Board, if one shall have been
                  elected, or by any holder of at least 10% of the
                  outstanding stock entitled to vote at such meetings."

         ; and be it further

                  RESOLVED, that, the Corporation is hereby authorized to issue
         any all shares of the Corporation's common stock, par value $.001 per
         share, to be issued in connection with the proposed initial public
         offering of common stock, par value $.001, of the Corporation, in
         uncertificated form, in accordance with Article V, Section 1 of the
         By-Laws, as amended above.

                  This Unanimous Written Consent of the Board of Directors may
be executed in one or more counterparts, each of which shall be deemed an
original, but all of which together will constitute one and the same document.

                         THE TRANSFER OF THIS WARRANT IS
                         RESTRICTED AS DESCRIBED HEREIN

                     NOT EXERCISABLE PRIOR TO JUNE __, 1997
              VOID AFTER 5:00 P.M. NEW YORK TIME, ON JUNE __, 2001

                                  BIGMAR, INC.

                   Warrant to Purchase Shares of Common Stock


                                                                  125,000 Shares

         THIS  CERTIFIES  that,  for  receipt in hand of $125.00 and other value
received,  [NAME AND ADDRESS OF HOLDER] (the "Holder"), is entitled to subscribe
for, and purchase from,  BIGMAR,  INC., a Delaware  corporation (the "Company"),
upon the terms and conditions set forth herein, at any time or from time to time
after June __,  1997,  and before 5:00 P.M.  New York time on June __, 2001 (the
"Exercise  Period"),  125,000  shares of the Company's  common stock,  par value
$0.001 per share (the "Common Stock"),  subject to adjustment as provided herein
(the "Warrant Shares"), at a price of $_____ per share, subject to adjustment as
provided  herein (the "Exercise  Price").  This Warrant is not redeemable by the
Company.  This  warrant  is the  warrant or one of the  warrants  (collectively,
including any warrant issued upon the exercise or transfer of any such warrants,
in  whole  or in part,  the  "Warrants")  issued  pursuant  to the  Underwriting
Agreement,  dated  June  __,  1996,  between  the  Company  and the  Holder,  as
representative of the several  Underwriters named therein.  This Warrant may not
be sold, transferred,  assigned or hypothecated until June __, 1997, except that
it may be  transferred,  in  whole  or in  part,  at any time to (i) one or more
officers  of the Holder (who are either  stockholders  or  employees),  (ii) any
successor to the Holder or the officers or partners of such successor, (iii) any
purchaser of substantially all of the assets of the Holder, or (iv) by operation
of law.  As used herein,  the term "Holder" shall include any transferee to whom
this  Warrant has  been transferred in accordance with the immediately preceding
sentence.

         1.  Method of  Exercise.  This  Warrant  may be  exercised  during  the
Exercise Period,  as to the whole or any lesser number of Warrant Shares, by the
surrender of this Warrant (with the election at the end hereof duly executed) to
the Company at its offices at 6660 Doubletree Avenue, Columbus, Ohio 43229 or at
such other place as may be designated in writing by the Company, together with a
certified  or bank  cashier's  check  payable to the order of the  Company in an
amount equal to the Exercise  Price  multiplied by the number of Warrant  Shares
for which this Warrant is being  exercised.  Notwithstanding  the foregoing,  in
lieu of any cash payment  required  hereunder,  the Holder of this Warrant shall
have the right at any time during the Exercise Period to exercise the Warrant in
full or in part by surrender of this Warrant (with the

<PAGE>
<PAGE>



election  at the end hereof  duly  executed)  to the  Company at its  offices in
exchange for the number of Warrant Shares equal to the product of (a) the number
of Warrant Shares as to which the Warrant is being exercised multiplied by (b) a
fraction,  the  numerator  of which is the Current  Market  Price (as defined in
Section  5(b)  below)  of the  Common  Stock  less the  Exercise  Price  and the
denominator of which is the Current Market Price.

         2. Issuance of  Certificates.  Upon each exercise of the Holder's right
to  purchase  Warrant  Shares,  the  Holder  shall be deemed to be the holder of
record of the Warrant Shares issuable upon such exercise,  notwithstanding  that
the  transfer  books  of the  Company  shall  then  be  closed  or  certificates
representing such Warrant Shares shall not then have been actually  delivered to
the Holder. As soon as practicable after each such exercise of this Warrant, the
Company shall issue and deliver to the Holder a certificate or certificates  for
the Warrant Shares  issuable upon such  exercise,  registered in the name of the
Holder or its designee.  If this Warrant should be exercised in part only,  upon
surrender  of this  Warrant  for  cancellation,  the Company  shall  execute and
deliver a new Warrant evidencing the right of the Holder to purchase the balance
of the Warrant Shares (or portions thereof) subject to purchase hereunder.

         3.  Recording  of Transfer.  Any  Warrants  issued upon the transfer or
exercise in part of this Warrant  shall be numbered and shall be registered in a
Warrant Register as they are issued.  The Company shall be entitled to treat the
registered  holder of any Warrant on the  Warrant  Register as the owner in fact
thereof for all purposes and shall not be bound to  recognize  any  equitable or
other claim to or interest in such Warrant on the part of any other person,  and
shall not be liable for any  registration  or  transfer  of  Warrants  which are
registered  or to be  registered  in the name of a fiduciary or the nominee of a
fiduciary  unless made with the actual  knowledge that a fiduciary or nominee is
committing a breach of trust in requesting  such  registration  or transfer,  or
with the knowledge of such facts that its  participation  therein amounts to bad
faith.  This Warrant shall be transferable only on the books of the Company upon
delivery  thereof duly  endorsed by the Holder or by his or its duly  authorized
attorney or  representative,  or accompanied  by proper  evidence of succession,
assignment  or authority  to transfer.  In all cases of transfer by an attorney,
executor,   administrator,   guardian  or  other  legal   representative,   duly
authenticated  evidence  of his or its  authority  shall be  produced.  Upon any
registration of transfer, the Company shall deliver a new Warrant or Warrants to
the person entitled thereto. This Warrant may be exchanged, at the option of the
Holder   hereof,   for  another   Warrant,   or  other   Warrants  of  different
denominations,  of like tenor and  representing  in the  aggregate  the right to
purchase a like number of Warrant Shares (or portions  thereof),  upon surrender
to the Company or its duly authorized agent.

         4.  Reservation of Common Stock. The Company shall at all times reserve
and keep available out of its authorized and unissued  Common Stock,  solely for
the purpose of providing for the exercise of the Warrants, such number of shares
of Common Stock as shall, from time to time, be sufficient therefor. The Company
covenants  that all  shares of  Common  Stock  issuable  upon  exercise  of this
Warrant,  upon  receipt by the Company of the full  payment  therefor,  shall be
validly issued, fully paid, nonassessable and free of preemptive rights.

         5.  Exercise  Price   Adjustments  and  Warrant  Shares  Issuable  Upon
Exercise.  Subject to the  provisions  of this Section 5, the Exercise  Price in
effect from time to time and the number of Warrant Shares issuable upon exercise
of the Warrants shall be subject to adjustment, as follows:

                  (a) In case  the  Company  shall at any  time  after  the date
hereof (i) declare a dividend on the outstanding  Common Stock payable in shares
of its capital stock, (ii) subdivide the outstanding Common Stock, (iii) combine
the outstanding  Common Stock into a smaller number of shares, or (iv) issue any
shares of its capital stock by  reclassification  of the Common Stock (including
any such  reclassification in connection with the consolidation or merger of the
Company  with or into another  corporation),  then,  in each case,  the Exercise
Price in effect, and the number of shares of Common Stock issuable upon exercise
of the Warrants outstanding, at the time of the record date for such dividend or
at the effective  date of such  subdivision,  combination  or  reclassification,
shall be proportionately  adjusted so that the holder of the Warrants after such
time shall be entitled to receive the same number and kind of shares  which,  if
such Warrants had been exercised  immediately  prior to such time,  such holders
would have owned upon such  exercise  and been  entitled to receive by virtue of
such dividend,  subdivision,  combination or  reclassification.  Such adjustment
shall be made successively whenever any event listed above shall occur.

                  (b) In  case  the  Company  shall  issue  rights,  options  or
warrants to subscribe for or purchase  Common Stock (or  securities  convertible
into or  exchangeable  for,  Common  Stock) at a price  per  share (or  having a
conversion  price per share, if a security is convertible  into, or exchangeable
for,  Common Stock) less than the Current Market Price per share of Common Stock
(as determined  pursuant to Section 5(h) hereof) in effect  immediately prior to
the earlier of the issuance thereof or the record date therefor, then, effective
immediately  following  the earlier of the issuance of such  rights,  options or
warrants  or the record  date  therefor,  as the case may be, in each case,  the
Exercise  Price shall be adjusted by  multiplying  the Exercise  Price in effect
immediately  prior to such  issuance  or record  date,  as the case may be, by a
fraction,  the  numerator  of which shall be the sum of (i) the total  number of
shares of Common Stock  outstanding  on such date, and (ii) the number of shares
of Common Stock which the aggregate  exercise,  conversion or exchange  price of
the  rights,  options or warrants to be issued  would  purchase at such  Current
Market Price,  and the  denominator of which shall be the total number of shares
of Common Stock outstanding on such date plus the number of additional shares of
Common  Stock to be offered  for  subscription  or  purchase  (or into which the
convertible  or   exchangeable   securities  so  to  be  offered  are  initially
convertible or exchangeable).  In case any subscription  price may be paid for a
consideration part or all of which shall be in a form other than cash, the value
of such  consideration  shall be as  determined  in good  faith by the  Board of
Directors  of the  Company,  whose  determination  shall  be  conclusive  absent
manifest error. If any change shall occur in the price per share provided for in
any of the options,  rights or warrants  referred to in this Section 5(b), or in
the price per share or ratio at which the securities referred to in this Section
5(b) are convertible or exchangeable (in either case, other than changes in such
prices or ratios arising pursuant to anti-dilution  adjustments in such options,
rights,  warrants,  convertible or  exchangeable  securities or the  instruments
pursuant to which they

                                       -3-
<PAGE>
<PAGE>



were issued,  provided  that such  options,  rights,  warrants,  convertible  or
exchangeable securities or instruments pursuant to which they were issued do not
contain  anti-dilution  provisions any more favorable to the holder thereof than
those  contained  herein),  such options,  rights or warrants or  convertible or
exchangeable  securities,  as the case may be,  to the  extent  not  theretofore
exercised,  shall be deemed to have expired or  terminated on the date when such
price  change  became  effective  in respect of shares  not  theretofore  issued
pursuant to the  exercise or  conversion  or exchange  thereof,  and the Company
shall be deemed to have issued upon such date new options, rights or warrants or
convertible or exchangeable securities.

                  (c) In case the  Company  shall  sell or  otherwise  issue any
shares  of Common  Stock for a  consideration  per share  less than the  Current
Market Price (as  determined  pursuant to Section 5(h)  hereof),  then,  in each
case,  the  Exercise  Price in effect  immediately  prior to such sale  shall be
adjusted to a price  determined  by  multiplying  the  Exercise  Price in effect
immediately prior to such sale by a fraction the numerator of which shall be the
sum of (i) the total  number of shares of Common Stock  outstanding  immediately
prior to such sale,  and (ii) the number of shares of Common Stock that could be
purchased at the Current Market Price in effect  immediately  prior to such sale
or other issuance for the consideration received by the Company upon the sale or
other issuance, and the denominator of which shall be the total number of shares
of Common Stock outstanding immediately after such sale; provided, however, that
in no event shall the Exercise Price be adjusted pursuant to this computation to
an amount in excess of the Exercise  Price in effect  immediately  prior to such
computation.  For the purposes of any  adjustment to be made in accordance  with
this Section 5(c),  in case of the sale or other  issuance of Common Stock for a
consideration part or all of which shall be cash, the amount of the cash portion
of the consideration  therefor deemed to have been received by the Company shall
be (i) the  subscription  price,  if shares of Common  Stock are  offered by the
Company for  subscription,  or (ii) the public offering price (before  deducting
therefrom any compensation paid or discount allowed in the sale, underwriting or
purchase  thereof  by  underwriters  or  dealers  or others  performing  similar
services),  if such  securities are sold to  underwriters  or dealers for public
offering  without a  subscription  offering,  or (iii) the gross  amount of cash
actually  received by the Company for such securities in any other case, in each
case,  without  deduction for any expenses incurred by the Company in connection
with such  transaction.  In case of the sale of  shares  of  Common  Stock for a
consideration part or all of which shall be in a form other than cash, the value
of such  consideration  shall be as  determined  in good  faith by the  Board of
Directors  of the  Company,  whose  determination  shall  be  conclusive  absent
manifest error.

                  (d) In case the  Company  shall  distribute  to all holders of
Common Stock  (including any such  distribution  made to the stockholders of the
Company in connection with a consolidation or merger in which the Company is the
continuing  corporation)  evidences of its  indebtedness,  cash or assets (other
than  distributions and dividends  payable in shares of Common Stock),  then, in
each case,  the  Exercise  Price shall be adjusted by  multiplying  the Exercise
Price in effect  immediately  prior to the record date for the  determination of
stockholders entitled to receive such distribution by a fraction,  the numerator
of which shall be the Current  Market Price (as  determined  pursuant to Section
5(h) hereof) per share of Common Stock on such record date,

                                       -4-
<PAGE>
<PAGE>



less the  fair  market  value  (as  determined  in good  faith  by the  Board of
Directors  of the  Company,  whose  determination  shall  be  conclusive  absent
manifest  error) of the portion of the evidences of indebtedness or assets so to
be  distributed,  or the amount of such cash,  applicable to one share of Common
Stock, and the denominator of which shall be such Current Market Price per share
of Common Stock. Such adjustment shall become effective at the close of business
on such record date.

                  (e) In any case in which this Section 5 shall  require that an
adjustment in the number of Warrant Shares be made effective as of a record date
for a specified  event (an "Event"),  the Company may elect to defer,  until the
occurrence of such Event,  issuing to the Holder,  if the Holder  exercised this
Warrant  after such record date,  the shares of Common Stock,  if any,  issuable
upon such exercise over and above the number of Warrant Shares, if any, issuable
upon such exercise on the basis of the number of Warrant  Shares in effect prior
to such  adjustment;  provided,  however,  that the Company shall deliver to the
Holder an appropriate  instrument  evidencing the Holder's right to receive such
additional shares upon the occurrence of the Event requiring such adjustment.

                  (f) Whenever  there shall be an adjustment as provided in this
Section 5, the Company shall,  within five (5) business days  thereafter,  cause
written notice thereof to be sent by registered mail,  postage  prepaid,  to the
Holder, at his or its address as it shall appear in the Warrant Register,  which
notice shall be accompanied by an officer's certificate setting forth the number
of Warrant Shares  issuable  hereunder and the exercise price thereof after such
adjustment  and setting  forth a brief  statement  of the facts  requiring  such
adjustment and the computation  thereof,  which officer's  certificate  shall be
conclusive  evidence of the correctness of any such  adjustment  absent manifest
error.

                  (g) The Company  shall not be required to issue  fractions  of
shares of Common Stock or other  capital  stock of the Company upon the exercise
of this Warrant.  If any fraction of a share would be issuable upon the exercise
of this Warrant (or specified portions thereof), the Company shall purchase such
fraction for an amount in cash equal to the same fraction of the Current  Market
Price of such share of Common Stock on the date of exercise of this Warrant.

                  (h) The  "Current  Market  Price" per share of Common Stock on
any date shall be deemed to be the average of the daily  closing  prices for the
thirty (30) consecutive trading days immediately preceding the date in question.
The closing  price for each day shall be the last  reported  sales price regular
way or, in case no such  reported  sale takes place on such day, the closing bid
price regular way, in either case on the principal national  securities exchange
(including,  for purposes hereof,  the Nasdaq National  Market(TM)) on which the
Common  Stock is listed or admitted to trading,  or, if the Common  Stock is not
listed or admitted to trading on any national securities  exchange,  the highest
reported bid price for the Common Stock as furnished by the National Association
of Securities Dealers,  Inc. (the "NASD") or a similar  organization if the NASD
is no longer reporting such information  (including for purposes hereof Nasdaq).
If on any such date the Common Stock is not listed or admitted to trading on any
national

                                       -5-
<PAGE>
<PAGE>



securities  exchange and is not quoted by The Nasdaq Stock  Market,  Inc. or any
similar organization, the fair value of a share of Common Stock on such date, as
determined  in good  faith  by the  Board of  Directors  of the  Company,  whose
determination shall be conclusive absent manifest error, shall be used.

                  (i) No adjustment  in the Exercise  Price shall be required if
such  adjustment is less than $0.05;  provided,  however,  that any  adjustments
which by reason of this  Section 5 are not  required to be made shall be carried
forward and taken into account in any subsequent  adjustment.  All  calculations
under this  Section 5 shall be made to the  nearest  cent.  For  purposes of any
calculation pursuant to this Section 5, shares of Common Stock owned by, or held
for the account of, the Company shall not be deemed  outstanding for the purpose
of any such computation.

                  (j) Upon each  adjustment of the Exercise Price as a result of
the calculations made in this Section 5, the Warrants shall thereafter  evidence
the right to purchase,  at the adjusted Exercise Price, that number of shares of
Common Stock (calculated to the nearest hundredth)  obtained by dividing (i) the
product obtained by multiplying the number of shares of Common Stock purchasable
upon exercise of the Warrants prior to any adjustment of the number of shares of
Common Stock by the Exercise Price in effect prior to adjustment of the Exercise
Price by (ii) the Exercise Price in effect after such adjustment of the Exercise
Price.

                  (k) Notwithstanding anything to the contrary contained herein,
no adjustment  of the Exercise  Price or in the number of shares of Common Stock
issuable  upon  exercise  of the  Warrants  shall be made as a result  of, or in
connection  with, (i) the issuance of stock options pursuant to the stock option
plans   described  in  the  Company's   Registration   Statement  on  Form  S-1,
Registration  Number  333-3830,  as being in  existence as of the date hereof so
long as the aggregate amount of Common Stock covered by all of such options does
not exceed 350,000  shares;  (ii) the issuance or sale of shares of Common Stock
upon the  exercise  of options  referred  to in clause (i) above,  and (iii) the
issuance of any shares of Common Stock upon exercise of the Warrants pursuant to
this Agreement.

         6. (a) Consolidations and Mergers.  In case of any consolidation  with,
or merger of the Company with or into,  another  corporation,  or in case of any
sale, lease or conveyance to another  corporation of all or substantially all of
the  property  and  assets  of  the  Company  (such  actions  being  hereinafter
collectively  referred  to as  "Reorganizations"),  there  shall  thereafter  be
deliverable  upon  exercise of this  Warrant (in lieu of the number of shares of
Common Stock theretofore  deliverable) the kind and amount of shares of stock or
other  securities,  cash or other  property  which  would  otherwise  have  been
deliverable  to a holder  of the  number of  shares  of  Common  Stock  upon the
exercise  of this  Warrant  upon such  Reorganization  if this  Warrant had been
exercised  in full  immediately  prior  to such  Reorganization.  In case of any
Reorganization, appropriate adjustment, as determined in good faith by the Board
of Directors of the Company,  shall be made in the application of the provisions
herein set forth with respect to the rights and  interests of the Holder so that
the  provisions set forth herein shall  thereafter be  applicable,  as nearly as
possible,  in relation to any shares or other  property  thereafter  deliverable
upon exercise


                                       -6-

of this  Warrant.  Any such  adjustment  shall be made by,  and set  forth in, a
supplemental  agreement between the Company,  or any successor thereto,  and the
Holder  and  shall  for all  purposes  hereof  conclusively  be  deemed to be an
appropriate  adjustment.  The Company  shall not effect any such  Reorganization
unless upon or prior to the consummation thereof the successor  corporation,  or
if the Company shall be the surviving corporation in any such Reorganization and
is not the issuer of the shares of stock or other  securities  or property to be
delivered to holders of shares of the Common Stock  outstanding at the effective
time thereof, then such issuer shall assume by written instrument the obligation
to  deliver  to the  Holder  such  shares  of stock,  securities,  cash or other
property as the Holder  shall be entitled  to  purchase in  accordance  with the
foregoing provisions.

                  (b) In case of any reclassification or change of the shares of
Common  Stock  issuable  upon  exercise  of  this  Warrant,  or in  case  of any
consolidation  or merger of another  corporation  into the  Company in which the
Company is the continuing  corporation and in which there is a  reclassification
or change (including a change to the right to receive cash or other property) of
the shares of Common  Stock,  the  Holder  shall  have the right  thereafter  to
receive upon  exercise of this  Warrant  solely the kind and amount of shares of
stock and other securities, property, cash or any combination thereof receivable
upon such reclassification,  change,  consolidation or merger by a holder of the
number of  shares  of Common  Stock  for  which  this  Warrant  might  have been
exercised immediately prior to such reclassification,  change,  consolidation or
merger.  Thereafter,  appropriate  provision shall be made for adjustments which
shall be as nearly equivalent as practicable to the adjustments in Section 5.

                  (c) The above  provisions  of this  Section 6 shall  similarly
apply to successive  reclassifications and changes of shares of Common Stock and
to successive consolidations, mergers, sales, leases, or conveyances.

         7.  Notice of Certain  Events.  In case at any time the  Company  shall
propose:

                  (a) to pay any dividend or make any  distribution on shares of
Common Stock in shares of Common Stock or to make any other  distribution to all
holders of Common Stock; or

                  (b) to issue any rights,  warrants or other  securities to all
holders of Common  Stock  entitling  them to purchase any  additional  shares of
Common Stock or any other rights, warrants or other securities; or

                  (c) to effect any  reclassification  or change of  outstanding
shares of Common Stock or any consolidation,  merger,  sale, lease or conveyance
of property, described in Section 6; or


                                       -7-
<PAGE>
<PAGE>



                  (d) to effect any  liquidation,  dissolution  or winding-up of
the Company;  then, and in any one or more of such cases, the Company shall give
written notice thereof,  by registered mail,  postage prepaid,  to the Holder at
the Holder's address as it shall appear in the Warrant Register, mailed at least
fifteen  (15)  business  days  prior to (i) the date as of which the  holders of
record of shares of Common  Stock to be entitled  to receive any such  dividend,
distribution, rights, warrants or other securities are to be determined or, (ii)
the date on which any such  reclassification,  change of  outstanding  shares of
Common  Stock,  consolidation,  merger,  sale,  lease,  conveyance  of property,
liquidation,  dissolution or winding-up is expected to become  effective and the
date as of which it is expected that holders of record of shares of Common Stock
shall be entitled to exchange their shares for securities or other property,  if
any,  deliverable  upon such  reclassification,  change of  outstanding  shares,
consolidation,   merger,  sale,  lease,  conveyance  of  property,  liquidation,
dissolution or winding-up.

         8.  Taxes.  The  issuance  of any shares or other  securities  upon the
exercise of this Warrant and the delivery of certificates  or other  instruments
representing such shares or other securities shall be made without charge to the
Holder  for any tax or other  charge in respect of such  issuance.  The  Company
shall not,  however,  be required to pay any tax which may be payable in respect
of any transfer  involved in the issue and delivery of any certificate in a name
other than that of the Holder.

         9. Registration Rights. (a) If at any time during the period commencing
on June  __,  1997 and  ending  on June  __,  2003,  the  Company  shall  file a
registration statement (other than on Form S-4, Form S-8, or any successor form)
with the  Securities and Exchange  Commission  (the  "Commission"),  the Company
shall give all the then holders of any Warrants or Warrant Shares (the "Eligible
Holders") at least thirty (30) days prior  written  notice of the filing of such
registration  statement.  If requested by any Eligible  Holder in writing within
thirty (30) days after  receipt of any such notice,  the Company  shall,  at the
Company's sole expense (other than the fees and disbursements of counsel for the
Eligible Holders and any underwriting discounts), register or qualify all or, at
each Eligible Holder's option, any portion of the Warrant Shares of any Eligible
Holder who shall have made such request,  concurrently  with the registration of
such other securities, all to the extent requisite to permit the public offering
and  sale of the  Warrant  Shares  through  the  facilities  of all  appropriate
securities  exchanges  and the  over-the-counter  market,  and will use its best
efforts  through its  officers,  directors,  auditors  and counsel to cause such
registration statement to become effective as promptly as practicable.

                  (b) If, on any two occasions  during the period  commencing on
June __, 1996 and ending on June __, 2000,  the Company  shall receive a written
request from Eligible  Holders who in the aggregate own (or upon exercise of all
Warrants then outstanding would own) a majority of the total number of shares of
Common  Stock then  included (or upon such  exercises  would be included) in the
Warrant Shares (the "Majority Holders"),  to register the sale of all or part of
such Warrant Shares,  the Company shall,  as promptly as practicable,  but in no
event later than 60 days  following the date of such  request,  prepare and file
with the  Commission a  registration  statement  sufficient to permit the public
offering and sale of the Warrant Shares


                                       -8-
<PAGE>
<PAGE>



through  the  facilities  of  all  appropriate   securities  exchanges  and  the
over-the-counter  market,  and will use its best efforts  through its  officers,
directors,  auditors and counsel to cause such registration  statement to become
effective as promptly as practicable;  provided,  that the Company shall only be
obligated for all expenses (other than underwriting  discounts)  incurred by the
Holders in connection with the first filing of the registration  statement under
this Section  9(b).  Within five (5) business  days after  receiving any request
contemplated  by this Section 9(b), the Company shall give written notice to all
the other Eligible Holders, advising each of them that the Company is proceeding
with such registration and offering to include therein all or any portion of any
such other Eligible Holders' Warrant Shares,  provided that the Company receives
a written  request to do so from such Eligible  Holders  within thirty (30) days
after receipt by them of the Company's notice.

                  (c) In the event of a registration  pursuant to the provisions
of this  Section 9, the Company  shall use its best efforts to cause the Warrant
Shares so registered to be registered or qualified for sale under the securities
or blue  sky  laws of such  jurisdictions  as the  Holder  or such  holders  may
reasonably request.

                  (d) The  Company  shall keep  effective  any  registration  or
qualification contemplated by this Section 9 and shall, from time to time, amend
or supplement each applicable  registration  statement,  preliminary prospectus,
final  prospectus,  application,  document and  communication for such period of
time as shall be required to permit the  Eligible  Holders to complete the offer
and sale of the Warrant Shares covered thereby. The Company shall in no event be
required to keep any such  registration or  qualification in effect for a period
in excess of nine (9) months  from the date on which the  Eligible  Holders  are
first free to sell such Warrant Shares; provided,  however, that, if the Company
is  required  to keep any such  registration  or  qualification  in effect  with
respect to  securities  other than the Warrant  Shares  beyond such period,  the
Company shall keep such registration or qualification in effect as it relates to
the Warrant Shares for so long as such registration or qualification  remains or
is required to remain in effect in respect of such other securities.

                  (e) In the event of a registration  pursuant to the provisions
of this Section 9, the Company shall furnish to each Eligible Holder such number
of copies of the  registration  statement and of each  amendment and  supplement
thereto (in each case, including all exhibits), such reasonable number of copies
of each prospectus contained in such registration  statement and each supplement
or amendment thereto (including each preliminary prospectus), all of which shall
conform to the  requirements of the Securities Act and the rules and regulations
thereunder,  and such other  documents,  as any Eligible  Holder may  reasonably
request to facilitate the  disposition  of the Warrant  Shares  included in such
registration.

                  (f) In the event of a registration  pursuant to the provisions
of this Section 9, the Company shall furnish each Eligible Holder of any Warrant
Shares so registered  with an opinion of its counsel  (reasonably  acceptable to
the  Eligible  Holders) to the effect that (i) the  registration  statement  has
become  effective under the Securities Act of 1933, as amended (the  "Securities
Act"), and no order suspending the effectiveness of the registration statement,


                                       -9-
<PAGE>
<PAGE>



preventing or suspending the use of the registration statement,  any preliminary
prospectus, any final prospectus or any amendment or supplement thereto has been
issued,  nor has the  Commission or any  securities or blue sky authority of any
jurisdiction  instituted or threatened to institute any proceedings with respect
to such an order, (ii) the registration  statement and each prospectus forming a
part thereof  (including  each  preliminary  prospectus),  and any  amendment or
supplement thereto,  complies as to form with the Securities Act, and (iii) such
counsel  has no  knowledge  of any  material  misstatement  or  omission in such
registration  statement  or any  prospectus,  as amended or  supplemented.  Such
opinion shall also state the jurisdictions in which the Warrant Shares have been
registered or qualified for sale pursuant to the provisions of Section 9(c).

                  (g) In the event of a registration  pursuant to the provisions
of this Section 9, the Company shall enter into a cross-indemnity  agreement and
a contribution agreement, each in customary form, with each underwriter, if any,
and, if requested,  enter into an underwriting agreement containing conventional
representations,  warranties,  allocation  of  expenses  and  customary  closing
conditions,  including, without limitation, opinions of counsel and accountants'
cold comfort letters, with any underwriter who acquires any Warrant Shares.

                  (h) The Company  agrees that until the later of (i) the period
when all of the Warrants Shares have been sold under a registration statement or
pursuant to Rule 144 under the  Securities  Act or (ii) June __, 2003,  it shall
keep current in filing all reports,  statements and other materials  required to
be filed with the  Commission  to permit  holders of the Warrant  Shares to sell
such securities under Rule 144.

                  (i) The Company will not, without the prior written consent of
the  Majority  Holders,  grant to any person the right to request the Company to
register any securities of the Company.

                  (j)  Notwithstanding  the  forgoing,  if the Company shall not
have filed a  registration  statement  for the  Warrant  Shares  within the time
period  specified  in Section  9(b) hereof or the  Company  shall be in material
breach of any other  provision  specified in this Section 9 or Section 5 hereof,
the Company shall, upon written notice of the Holder,  repurchase the Warrant at
a price  equal to the  Current  Market  Price  less  the  Exercise  Price.  Such
repurchase shall be in immediately  available funds and shall close within three
(3)  business  days after the Holder has  provided  the Company with a notice of
election provided pursuant hereto.

         10. (a) Indemnification and Contribution. Subject to the conditions set
forth below,  the Company  agrees to indemnify  and hold  harmless each Eligible
Holder, its officers,  directors,  partners,  employees, agents and counsel, and
each person,  if any, who controls any such person within the meaning of Section
15 of the  Securities  Act or Section  20(a) of the  Securities  Exchange Act of
1934,  as amended  (the  "Exchange  Act"),  from and  against  any and all loss,
liability,  charge,  claim,  damage and expense whatsoever (which shall include,
for all purposes of this Section 10, without limitation, attorneys' fees and any
and all expenses  whatsoever  incurred in investigating,  preparing or defending
against any litigation, commenced


                                      -10-
<PAGE>
<PAGE>



or  threatened,  or any  claim  whatsoever,  and  any and  all  amounts  paid in
settlement of any claim or  litigation),  as and when incurred,  arising out of,
based upon, or in  connection  with (i) any untrue  statement or alleged  untrue
statement  of a material  fact or any  omission  or alleged  omission to state a
material fact required to be stated  therein or necessary to make the statements
therein not misleading contained in (A) any registration statement,  preliminary
prospectus or final prospectus (as from time to time amended and  supplemented),
or any  amendment  or  supplement  thereto,  relating  to the sale of any of the
Warrant Shares,  or (B) any application or other document or  communication  (in
this Section 10 collectively  called an "application")  executed by or on behalf
of the Company or based upon  written  information  furnished by or on behalf of
the Company filed in any jurisdiction in order to register or qualify any of the
Warrant  Shares under the  securities or blue sky laws thereof or filed with the
Commission or any  securities  exchange,  unless such  statement or omission was
made in reliance upon and in conformity  with written  information  furnished to
the Company with respect to such Eligible  Holder by or on behalf of such person
expressly for inclusion in any registration  statement,  preliminary prospectus,
or  final  prospectus,  or  any  amendment  or  supplement  thereto,  or in  any
application,  as the case  may be,  or (ii) any  breach  of any  representation,
warranty,  covenant or agreement of the Company  contained in this Warrant.  The
foregoing  agreement  to  indemnify  shall be in addition to any  liability  the
Company may otherwise have, including liabilities arising under this Warrant.

         If any  action is brought  against  any  Eligible  Holder or any of its
officers, directors,  partners, employees, agents or counsel, or any controlling
persons of such person (an  "indemnified  party") in respect of which  indemnity
may be sought  against the Company  pursuant to the  foregoing  paragraph,  such
indemnified   party  or  parties  shall  promptly  notify  the  Company  of  the
institution  of such action (but the failure so to notify  shall not relieve the
Company from any liability  other than  pursuant to this Section  10(a)) and the
Company  shall  promptly  assume  the  defense  of such  action,  including  the
employment of counsel  (reasonably  satisfactory  to such  indemnified  party or
parties) and the payment of expenses.  Such  indemnified  party or parties shall
have the right to employ its or their own counsel in any such case, but the fees
and expenses of such counsel shall be at the expense of such  indemnified  party
or parties unless (I) the employment of such counsel shall have been  authorized
in writing by the Company in  connection  with the defense of such action,  (II)
the Company shall not have promptly employed counsel reasonably  satisfactory to
such  indemnified  party or (III) the  parties to have  charge of the defense of
such action or such indemnified party or parties shall have reasonably concluded
that there may be one or more legal defenses available to it or them or to other
indemnified parties which are different from or additional to those available to
the Company, in any of which events such fees and expenses shall be borne by the
Company,  and the Company shall not have the right to direct the defense of such
action on behalf of the  indemnified  party or parties.  The Company  shall not,
without the prior written consent of each indemnified party that is not released
as described in this  sentence,  settle or  compromise  any action,  or permit a
default or consent to the entry of judgment in or  otherwise  seek to  terminate
any pending or threatened  action,  in respect of which  indemnity may be sought
hereunder (whether or not any indemnified party is a party thereto), unless such
settlement, compromise, consent or termination includes an unconditional release
of each indemnified party from all liability in respect of such action.


                                      -11-

The Company agrees promptly to notify the Eligible  Holders of the  commencement
of any litigation or  proceedings  against the Company or any of its officers or
directors in connection  with the sale of any Warrant Shares or any  preliminary
prospectus,  prospectus,  registration  statement  or  amendment  or  supplement
thereto, or any application relating to any sale of any Warrant Shares.

                  (b) The  Holder  agrees to  indemnify  and hold  harmless  the
Company,  each  director  and officer of the Company who signs any  registration
statement covering Warrant Shares held by the Holder, each other person, if any,
who controls the Company  within the meaning of Section 15 of the Securities Act
or Section 20(a) of the Exchange Act, and its or their  respective  counsel,  to
the same  extent as the  foregoing  indemnity  from the Company to the Holder in
Section 10(a), but only with respect to statements or omissions, if any, made in
any registration statement,  preliminary prospectus or final prospectus,  or any
amendment or supplement thereto, or in any application,  in reliance upon and in
conformity with written information furnished to the Company with respect to the
Holder  by or on  behalf  of the  Holder  expressly  for  inclusion  in any such
registration  statement,  preliminary  prospectus  or final  prospectus,  or any
amendment or supplement thereto,  or in any application,  as the case may be. If
any  action  shall be  brought  against  the  Company  or any  other  person  so
indemnified based on any such registration statement,  preliminary prospectus or
final prospectus, or any amendment or supplement thereto, or in any application,
and in respect of which  indemnity may be sought against the Holder  pursuant to
this  Section  10(b),  the Holder  shall have the rights and duties given to the
Company  and the  Company and each other  person so  indemnified  shall have the
rights and duties given to the indemnified parties, by the provisions of Section
10(a).

                  (c) To provide for just and equitable contribution,  if (i) an
indemnified party makes a claim for indemnification pursuant to Section 10(a) or
10(b) (subject to the  limitations  thereof) but it is found in a final judicial
determination,  not subject to further appeal, that such indemnification may not
be enforced in such case,  even though this  Agreement  expressly  provides  for
indemnification  in such case, or (ii) any  indemnified  or  indemnifying  party
seeks contribution under the Securities Act, the Exchange Act or otherwise, then
the Company (including for this purpose any contribution made by or on behalf of
any  director  of the  Company,  any  officer of the Company who signed any such
registration statement,  any controlling person of the Company, and its or their
respective  counsel),  as one entity,  and the  Eligible  Holders of the Warrant
Shares  included  in such  registration  in the  aggregate  (including  for this
purpose any contribution by or on behalf of an indemnified  party),  as a second
entity,  shall  contribute  to the  losses,  liabilities,  claims,  damages  and
expenses  whatsoever  to  which  any of them  may be  subject,  on the  basis of
relevant equitable  considerations such as the relative fault of the Company and
such  Eligible  Holders in  connection  with the facts  which  resulted  in such
losses,  liabilities,  claims,  damages and expenses. The relative fault, in the
case of an untrue  statement,  alleged  untrue  statement,  omission  or alleged
omission,  shall be determined by, among other things,  whether such  statement,
alleged statement,  omission or alleged omission relates to information supplied
by the Company or by such Eligible  Holders,  and the parties'  relative intent,
knowledge,  access to  information  and  opportunity  to correct or prevent such
statement, alleged statement,  omission or alleged omission. The Company and the
Holder agree


                                      -12-
<PAGE>
<PAGE>



that it would be unjust and  inequitable  if the  respective  obligations of the
Company and the Eligible Holders for contribution were determined by pro rata or
per capita allocation of the aggregate losses, liabilities,  claims, damages and
expenses (even if the Holder and the other  indemnified  parties were treated as
one entity for such purpose) or by any other method of allocation  that does not
reflect the equitable  considerations  referred to in this Section 10(c).  In no
case shall any Eligible Holder be responsible for a portion of the  contribution
obligation imposed on all Eligible Holders in excess of its pro rata share based
on the  number of shares of Common  Stock  owned (or which  would be owned  upon
exercise  of all Warrant  Shares) by it and  included  in such  registration  as
compared to the number of shares of Common  Stock owned (or which would be owned
upon  exercise of all Warrant  Shares) by all  Eligible  Holders and included in
such registration.  No person guilty of a fraudulent  misrepresentation  (within
the  meaning of  Section  11(f) of the  Securities  Act)  shall be  entitled  to
contribution   from  any   person   who  is  not   guilty  of  such   fraudulent
misrepresentation.  For purposes of this Section 10(c), each person, if any, who
controls any Eligible  Holder within the meaning of Section 15 of the Securities
Act or Section  20(a) of the Exchange Act and each officer,  director,  partner,
employee, agent and counsel of each such Eligible Holder or control person shall
have the same rights to  contribution  as such Eligible Holder or control person
and each person,  if any, who controls the Company within the meaning of Section
15 of the  Securities  Act or Section 20(a) of the Exchange Act, each officer of
the Company who shall have signed any such registration statement, each director
of the Company and its or their respective counsel shall have the same rights to
contribution  as the  Company,  subject in each case to the  provisions  of this
Section 10(c).  Anything in this Section 10(c) to the contrary  notwithstanding,
no party shall be liable for contribution  with respect to the settlement of any
claim or action  effected  without its written  consent.  This Section  10(c) is
intended to supersede any right to  contribution  under the Securities  Act, the
Exchange Act or otherwise.

         11.  Legend.  Unless a  current  registration  statement  covering  the
Warrant Shares is in effect under the Securities  Act, the Warrant Shares issued
upon exercise of the Warrant shall bear the following legend:

                  "THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT
         BEEN REGISTERED UNDER THE  SECURITIES ACT OF 1933, AS
         AMENDED (THE "SECURITIES ACT").  SUCH SHARES MAY NOT BE
         OFFERED OR SOLD EXCEPT PURSUANT TO AN EFFECTIVE
         REGISTRATION STATEMENT UNDER THE SECURITIES ACT, OR AN
         EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT."


         12.  Replacement  of  Warrants.  Upon  receipt of  evidence  reasonably
satisfactory to the Company of the loss, theft, destruction or mutilation of any
Warrant (and upon  surrender  of any Warrant if  mutilated),  the Company  shall
promptly  execute and deliver to the Holder  thereof a new Warrant of like date,
tenor and denomination.


                                      -13-
<PAGE>
<PAGE>



         13. No Rights as Shareholder. The Holder of any Warrant shall not have,
solely on account of such status,  any rights of a  shareholder  of the Company,
either at law or in equity,  or to any notice of meetings of  stockholders or of
any other proceedings of the Company, except as provided in this Warrant.

         14.  Governing Law. This Warrant shall be construed in accordance  with
the laws of the State of New York  applicable  to contracts  made and  performed
within such State, without regard to principles of conflicts of law.

         15.  Modification  of  Agreement.  This Warrant  shall not otherwise be
modified,  supplemented  or amended in any  respect  unless  such  modification,
supplement  or  amendment  is in writing and signed by the party  against  which
enforcement of the same is sought.

         16. Consent to Jurisdiction.  The Company  irrevocably  consents to the
jurisdiction  of the  courts of the State of New York and of any  Federal  court
located in such state in connection with any action or proceeding arising out of
or relating to this Warrant,  any document or instrument  delivered pursuant to,
in connection  with or  simultaneously  with this  Warrant,  or a breach of this
Warrant or any such document or  instrument.  In any such action or  proceeding,
the Company waives personal  service of any summons,  complaint or other process
and agrees that service thereof may be made in accordance with Section 12 of the
Underwriting Agreement.

appoint  a  successor   Representative   to  act   thereafter   as  the  Protyde
Representative.  In the event that the Protyde Representative  determines in his
or her sole  discretion that the interests of PSub would be better served by the
appointment of a new Protyde Representative,  he or she shall so notify PSub and
shall be  entitled  thereafter  to  resign.  If PSub  shall  fail to  appoint  a
successor  Representative  or does not notify BSub of the name of such successor
within 10 days after being  requested to do so by BSub, then BSub shall select a
successor Protyde Representative from among the officers of PSub and such


                                       -4-

choice shall be binding  upon PSub;  provided,  that any Protyde  Representative
selected by BSub may at any time be replaced by PSub.


               (ii) For purposes of this Agreement,  the "BigMar Representative"
shall be John Tramontana and such successor BigMar Representatives as BSub shall
designate from time to time. If the party serving as BigMar Representative shall
be unable to act as BigMar Representative, BSub shall appoint a successor BigMar
Representative to act thereafter as the BigMar Representative. In the event that
the BigMar  Representative  determines  in his or her sole  discretion  that the
interests  of BSub  would be better  served by the  appointment  of a new BigMar
Representative,  he or she shall so notify BSub and shall be entitled thereafter
to resign.  If BSub shall fail to appoint a successor BigMar  Representative  or
does not notify  PSub of the name of such  successor  within 10 days after being
requested  to  do so  by  PSub,  then  PSub  shall  select  a  successor  BigMar
Representative  from among the  officers  and such choice  shall be binding upon
BSub; provided,  that any BigMar Representative selected by PSub may at any time
be replaced by BSub.


               (iii) The Protyde  Representative  and the BigMar  Representative
are sometimes collectively referred to herein as the "Representatives."  Each of
the  parties  hereby   irrevocably   constitutes  and  appoints  its  respective
Representative,  acting  alone,  as such  party's  true and lawful  attorney  to
perform on its behalf all acts which by the  provisions of this Agreement are to
be performed  by it; to execute and give and receive on such party's  behalf all
notices,  requests,  consents,  amendments,  demands and other communi-

cations to them  hereunder;  to delegate to any Persons in writing all or any of
such Representative's  power and authority hereunder in the event of the absence
or  incapacity  to act, and  generally to act for such party and on such party's
behalf in all matters  connected  with this Agreement as fully and with the same
force and effect as each such party might act in person.  This power of attorney
is deemed to be coupled with an interest,  shall be irrevocable and shall not be
affected by the subsequent dissolution of the appointing party.


               (iv) The  Representatives  shall act,  without  compensation,  on
behalf of their respective appointing parties, and the Representatives shall not
be liable to their  respective  appointing  parties for any action taken in good
faith on behalf of such party.


               (v) The  parties  shall be entitled to rely on the full power and
authority of the  Representatives to act hereunder on behalf of their respective
appointing  parties  until  notice of  resignation  or  removal  is given by the
appointing  party,  and neither party shall be liable in any way  whatsoever for
any action it takes or omits to take in reliance upon the power and authority of
the other party's Representative.

from BigMar such  extensions  of credit in respect of the  payments for Products
under the  Manufacturing  Agreement as BigMar shall determine to be commercially
reasonable, and thereafter, if and to the extent necessary, additional loans and
capital contributions shall be made as follows:


               (i) PSub shall make loans to the Partnership of the Partnership's
working  capital  requirements  as  determined by PSub and  consistent  with the
Partnership's  budget and not already  contributed  under  Section  4.1, up to a
total of  $500,000 in the  aggregate.  All such loans  shall be  evidenced  by a
promissory note of the  Partnership,  substantially  in the form of Exhibit 5.1,
bearing interest at a rate per annum equal to the prime commercial  lending rate
for short-term  loans announced from time to time by Chase Manhattan Bank, N.A.,
at its  offices  in New York City,  plus 2%,  and be  entitled  to  priority  in
repayment pursuant to the terms of Section 7.3 hereof.


               (ii) If PSub has made loans to the  Partnership  under clause (i)
above of $500,000 in the aggregate,  the Partners shall make additional  capital
contributions,  in equal  amounts and at such times and in such manner as either
Partner  may request in writing,  in amounts  equal to all of the  Partnership's
working  capital  requirements  necessary to meet  expenses  provided for in the
Partnership's  then  current  budget.  Each such capital  contribution  shall be
credited to the capital account of the Partner making the contribution.

     In either case,  the Partners  shall be entitled to at least 15 days' prior
written  notice  before  any  loans  or  additional  capital  contributions  are
required,  and all  requests  for loans  under  clause  (i) must equal or exceed
$25,000 and all requests for additional capital  contributions under clause (ii)
must equal or exceed $50,000 in the aggregate.


               5.2 Failure to Contribute  Requested Capital.  If a Partner fails
to fund its proportionate share of a request for a capital  contribution made by
the other  Partner  pursuant to Section  5.1(ii)  within 30 days after notice of
such request under Section  5.l(ii),  the  requesting  Partner may at its option
fund the entire capital contribution.  In such event, all amounts so contributed
shall be credited  to the  capital  account of the  contributing  Partner.  If a
Partner fails to meet a request for capital under Section  5.1(ii) and the other
Partner  funds the  contribution,  the  non-contributing  Partner's  interest in
Partnership income,  losses, and distributions shall be adjusted as set forth in
Section 5.1.

made,  instituted or prosecuted by the Partnership if given, made, instituted or
prosecuted  by the other  Partner,  acting in its own name or in the name of the
Partnership.  Nothing in this Section 6.2 shall be construed to require approval

payment of all of the Partnership's premanufacturing,  manufacturing,  marketing
and administrative  expenses (including those to be incurred under the Agreement
and  the  Manufacturing   Agreement),   and  shall  submit  the  budget  to  the
Representatives for approval no later than December 1 of the preceding year. The
Representatives shall approve an annual budget no later than 30 days after it is

               (i) Net  income  of the  Partnership  shall be  allocated  to the
Partners  first,  in proportion to their  respective  negative  capital  account
balance,  if any,  until each  Partner's  capital  account  balance is zero, and
thereafter  equally  unless and until such time as one  Partner  makes a capital
contribution under Section 5.1(ii) not matched by the other Partner, after which
net income shall be allocated  to the  Partners in the  proportions  which their
respective  aggregate  capital  contributions  bear  to  the  aggregate  capital
contributions to the Partnership.

<PAGE>
<PAGE>


                   (ii) Net losses of the Partnership  shall be allocated to the
Partners in such manner as will most  quickly  cause  their  respective  capital
account balances to be equal.

at such times and in such amounts as the Representatives may determine, but only
after payment in full of all amounts loaned to the  Partnership by PSub pursuant
to clause (i) of Section  5.1  together  with all  accrued  and unpaid  interest
thereon.  Any  distributions  by the  Partnership  shall be divided  between the
Partners in  proportion  to their then current  capital  account  balances.  The
Partnership shall endeavor,  subject to the establishment of reasonable reserves
and its working  capital  requirements,  to distribute to each Partner  during a
calendar  year an amount equal to the income  allocated  to such Partner  during
that calendar year.


          9.   Representations and Warranties.

indemnification.   As  a  condition  to  the   indemnified   party's   right  to
indemnification under this Section 10.1, the indemnified party shall give prompt
notice  to the  indemnifying  party of any  suits,  claims or  demands  by third
parties  or the  indemnified  Partner  which may give rise to any Loss for which
indemnification  may be required under this Section 10.1. The indemnifying party
shall be entitled

to assume the  defense  and  control  of any suit,  claim or demand of any third
party at its own cost and  expense;  provided,  however,  that the  indemnifying
party  shall not be entitled to assume the defense and control of any such suit,
claim or demand if in the  opinion of  counsel  reasonably  satisfactory  to the
indemnifying  party,  the  indemnified  party  has  one or more  legal  defenses
available to it which are in conflict with those  available to the  indemnifying
party.  The  indemnifying  party  shall be free to settle any claim or action in
respect to which  indemnity  may be sought  against it pursuant to this Section;
provided,  however,  that the indemnifying party shall not settle any such claim
or  action  if such  settlement  would  result  in the  imposition  against  the
indemnified  party of a  judgment,  decree or order in the  nature of  equitable
relief without the consent of the indemnified  party, which consent shall not be
unreasonably withheld.


               10.2 Insurance.  If available at rates reasonably satisfactory to
the Partnership,  the Partners shall maintain insurance for its business, in its
own  name  or in the  name  of a  Partner  or its  Affiliate,  with  responsible
insurance  companies  satisfactory  to  the  Partnership,   insuring  the  risks
associated with the  Partnership's  business,  in such amounts as is customarily
maintained by similar businesses.

Agreement, shall be sold, assigned, exchanged,

pledged,  encumbered or otherwise  transferred without the prior written consent
of the  other  Partner.  Any  purported  transfer  not in  compliance  with this

of 50% or more of the  common  equity  or 50% or more of the  voting  rights  in
BigMar (whether in a single  transaction or a series of  transactions)  shall be
deemed a transfer of BSub's  interest in the  Partnership;  and (b) the transfer
after the execution and delivery of this  Agreement of 50% or more of the common
equity or 50% or more of the  voting  rights  in  Protyde  (whether  in a single

Information.

subject to reimbursement by the Partnership;  provided, however, that during the
term  of  the  Partnership  each  of the  Partners  shall  have a  royalty-free,
worldwide right (with no right to assign, except to its Affiliates, but with the
rights to have goods made to its order and to permit  purchasers of its goods to
use and sell  goods  so  purchased)  to use and  practice  any such  Proprietary
Information  and Marketing  Information for any purpose outside the scope of the

               12.3   Confidentiality.   Unless  otherwise   determined  by  the

be obtained from BigMar and Protyde,  respectively;  provided, however, that the
words  "Protyde" and "BigMar" may be included in the name of the Partnership and
may be used in combination in connection with the Partnership's business.

into existence upon the date hereof and,  unless extended or dissolved by mutual

2005, unless earlier dissolved in accordance with Section 13.2.



               13.2  Dissolution by Election of Partner.  The Partnership may be
terminated (i) by either  Partner upon the material  breach of this Agreement by
the other  Partner  if such  breach is not cured  within 30 days  after  written
notice from the nonbreaching  Partner;  provided,  however,  that termination of
this  Agreement is not  intended to be the sole remedy of either  Partner in the
event of a breach of this Agreement by the other Partner,  and in the event of a
breach of this Agreement by one Partner, the other Partner shall be entitled, in
addition,  to all remedies available at law or in equity; (ii) by either Partner
upon the  bankruptcy,  insolvency,  assignment  for the benefit of  creditors or
other act of insolvency  by, of or against the other  Partner or its parent,  if
any; or (iii) by BSub upon the termination of the Marketing Agreement or by PSub
upon termination of the  Manufacturing  Agreement.  The transfer by a Partner of
its interest in the Partnership on the terms permitted by this Agreement,  or on
terms specifically agreed to by the Partners,  shall not be deemed a dissolution
of the Partnership.


               14. Winding Up;  Distribution of Assets.  Upon the termination of
the Partnership for any reason, the affairs of the Partnership


                                       -24-

<PAGE>
<PAGE>


shall be wound up and the Partnership  dissolved as rapidly as circumstances and
orderly practice permit,  but in any event within a period of time not exceeding
six months,  and the assets of the  Partnership  shall be applied as provided in
this Section 14.


               14.1 Distribution of Proprietary and ANDA Rights upon Termination
under Section 13.1.  Subject to the provisions of Section 14.4, upon termination
of the  Partnership  pursuant to Section 13.1, all FDA approved  ANDA's shall be
assigned  to BSub;  provided,  however,  that PSub shall  have (i) a  worldwide,
royalty-free  right,  with full right of assignment and partial  assignment,  to
make  use of all  Proprietary  Information  owned or  controlled  by BSub or the
Partnership which relates to the manufacture of the Products,  (ii) the right to
use and reference any and all FDA-approved  ANDAs and ANDAs in progress relating
to the Products,  and (iii) the right to make,  use and sell each Product.  Each
Partner  shall  execute  such  agreements  and  documents  as may be  reasonably
requested by the other Partner,  and shall assist in obtaining all FDA and other
approvals  necessary  to give each Partner the full use of its rights under this
Section 14.1.  Automatically  upon the effectiveness of such assignment to BSub,
BSub's  Partnership  capital  account shall be reduced by an amount equal to the
value  attributed,  in Section 7.1, to its initial capital  contribution made in
accordance  with Section 4.2. The  provisions of this Section 14.1 shall survive
the termination of this Agreement for any reason.


               14.2  Distribution of Other Assets upon Termination under Section
13.1. Subject to the provisions of Section 14.4,


                                       -25-

<PAGE>
<PAGE>



upon the termination of the Partnership  pursuant to Section 13.1, the assets of
the  Partnership  other than those described in Section 14.1 shall be applied as
follows:


               (i)  first  to  the  payment  of  liabilities  and  discharge  of
obligations of the Partnership to persons other than the Partners and Affiliates
of Protyde and BigMar;


               (ii) next to the  repayment  of all loans to the  Partnership  by
PSub  pursuant  to  Section  5.1 hereof  together  with all  accrued  and unpaid
interest thereon;


               (iii) next to the payment of  liabilities  and  discharge  of any
obligations of the Partnership to the Partners,  and if the Partnership's assets
are insufficient to pay all such liabilities,  the Partner to which the greatest
amount is then owed shall be paid until the Partners are owed equal amounts and,
thereafter, the Partners shall be paid any remaining amounts equally;


               (iv) next to the  payment to each  Partner of an amount  equal to
its respective  capital account balance,  or if such assets or proceeds are less
than the aggregate capital account  balances,  in proportion to their respective
capital accounts;  provided,  however,  in any case, that BSub's capital account
shall  first have been  reduced in  accordance  with  Section  14.1 prior to any
distribution of Partnership assets pursuant to this Section 14; and


               (v) the  remainder,  if any, to the Partners in  accordance  with
their respective interests in Partnership net income under Section 8.1(i) at the
time of dissolution.

               14.3  Distribution of Assets upon Termination under Section 13.2.
If the  Partnership  is terminated  pursuant to the  provisions of Section 13.2,
then the Partner  electing  to dissolve  the  Partnership  shall have  exclusive
possession of all the assets of the Partnership  (other than the ANDA's) if such
Partner pays the other Partner the book value of its interest in the Partnership
at the time of  dissolution,  less the damages for any breach of this  Agreement
recoverable by the Partner electing to dissolve the Partnership. For purposes of
this Section 14.3, the "book value" of a Partner's  interest shall be the amount
such  Partner  would be entitled to receive  under  Section  14.2  pursuant to a
termination  of  the  Partnership  under  Section  13.1,  excluding  any  amount
attributable to goodwill.  If requested by the Partner  electing to dissolve the
Partnership,  the other Partner shall take all actions  reasonably  requested by
the dissolving  Partner in order to give the dissolving  Partner full possession
and use of the assets of the  Partnership  remaining  after  payment of the book
value of the other  Partner's  interest in the  Partnership  under this  Section
14.3.

            (b) Executive agrees that Employer in Employer's discretion, may
apply for and procure in the name of Executive and for its own benefit life

title or interest therein.

            (c) Executive represents and warrants that, to the best of

        11. In the event of Executive's death during the term of this Agreement,

<PAGE>



termination Employer shall be obligated to pay to Executive the Base Salary
which would otherwise be due Executive until the end of the month during which
the termination occurred plus six additional months of the Base Salary for the
Twelve-Month Period in which such termination occurred. If, prior to the date
specified on such notice, Executive's illness or incapacity shall have ceased
and Executive shall have resumed the performance of Executive's duties
hereunder, Executive shall be entitled to resume Executive's employment
hereunder as though such notice had not been given. Employer's Board of
Directors shall determine in good faith, upon consideration of medical evidence
satisfactory to it, whether Executive by reason of physical or mental disability
shall be unable to perform the services required of Executive hereunder.

        13. If Employer shall terminate Executive's employment hereunder for
Cause, as hereinafter defined, or if Executive shall voluntarily leave
Executive's employment hereunder, Employer will pay to Executive within ten days
after the termination of such Agreement an amount equal to the amount which
Executive would have earned as the Base Salary hereunder through the end of the
then current month in which such termination or departure occurred. Cause shall
mean any gross malfeasance directly and materially affecting Employer or
conviction of a felony directly and materially affecting Employer, each of
determined in the sole discretion of Employer.

        14. If Executive's employment is terminated by Employer without Cause,

the Base Salary for the Twelve-Month Period in which Executive was terminated.

        15. Executive covenants and agrees that any work or research, or the
result thereof, including without limitation, inventions, processes or formulae
made, conceived or developed by Executive, alone or in connection with others,
during Executive's employment with Employer, whether within or without the usual
hours of employment, which are directly related to the business, research,
development work or field of operation of Employer, or any of its subsidiaries
or affiliates, shall, at the option of Employer, to the extent of Executive's
interest therein, be the sole and exclusive property of Employer. Executive
further agrees to disclose all such inventions, processes and formulae
completely and in writing to the Board of Directors of Employer and to no other
persons unless so directed in writing by the Board of Directors of Employer. To
the extent of Executive's interest therein, at the option of Employer, all
papers and records of every kind, relating to any invention,
process, formula, improvement or patent included within the terms of this
Agreement, which shall at any time come into the possession of Executive shall
be the

                                       -3-

<PAGE>



sole and exclusive property of Employer and shall be surrendered to Employer
upon termination of Executive's employment by Employer or upon Employer's
request at any other time either during or after the termination of such
employment.

        16. Executive covenants and agrees with Employer that Executive has
not, and will not, during Executive's employment with Employer and thereafter,
directly or indirectly, use, communicate, disclose or disseminate to anyone
(except to the extent reasonably necessary for Executive to perform his duties
hereunder, except as required by law or except if generally available to the
public otherwise than through use, communication, disclosure or dissemination
by the Executive) any materials, documents or records containing confidential
information concerning the businesses or affairs of Employer or of any of its
affiliates or subsidiaries which Executive may have acquired in the course of or
as incident to Executive's employment or prior dealings with Employer or with
any of its affiliates or subsidiaries, including, without limitation, customer
lists, business or trade secrets of, or methods or techniques used by Employer
of any of its affiliates or subsidiaries in or about their respective busi-
nesses, or any information whatsoever concerning the customers or suppliers of
any of them.

        17. Executive acknowledges that Executive's services and
responsibilities are of particular significance to Employer and that Executive's
position with Employer has given and will give Executive a close knowledge of
its policies and trade secrets. 

            Executive covenants and agrees with Employer that Executive 
will not during Executive's employment with Employer and for a period
of two years after the termination of Executive's employment with Employer, in
any manner, directly or indirectly, (i) induce or attempt to influence any
present or future officer, employee, lessor, lessee, licensor, licensee or agent
of Employers or its subsidiaries or its affiliates to leave its respective
employ or solicit or divert or service any customers or clients of Employer or
its subsidiaries or its affiliates or (ii) alone or as a partner, officer,
director, employee, consultant or stockholder (except for ownership of no more
than 5% of the capital stock) of any corporation, partnership or other entity be
directly competitive with the business of Employer or its subsidiaries or
affiliates. For purposes of subdivision (ii) above of this paragraph 17, (a) a 
business shall be presumed to be directly competitive if it conducts in whole or
in part anywhere in Switzerland, Germany and the United States any business in 
which Employer, its subsidiaries or affiliates engages in during the term of
Executive's employment with Employer,

                                       -4-

<PAGE>
<PAGE>



and the burden of proving otherwise shall be on Executive, and (b) the
business activities of a subsidiary or division of a publicly held corporation
shall not be deemed to include the business activities of other subsidiaries
or divisions of such publicly held corporation.

        Nothing herein shall restrict or otherwise limit Executive from managing
Executive's private investments which are not directly competitive with the
businesses of Employer. Executive shall be permitted to serve as a director of
companies which are not directly competitive with the businesses of Employer,
so long as such services do not interfere with the performance of Executive's
duties under this Agreement.

        18. Executive acknowledges that the remedy at law for any breach or
threatened breach by Executive of the covenants contained in paragraphs 15, 16,
and 17 would be wholly inadequate, and therefore Employer or its subsidiaries
or its affiliates shall be entitled to preliminary and permanent injunctive
relief and specific performance thereof. Paragraphs 15, 16, and 17 constitute
independent and separable covenants that shall be enforceable notwithstanding
rights or remedies that Employer or its subsidiaries or it affiliates may have
under any other provision of this Agreement, or otherwise. If any or all of the
foregoing provisions of paragraphs 15, 16, and 17 are held to be unenforceable
for any reason whatsoever, it shall not in any way invalidate or affect the
remainder or this Agreement which shall remain in full force and effect. If the
period of time or geographical areas specified in paragraphs 15, 16, or 17 are
determined to be unreasonable in any judicial proceeding, the period of time or
areas of restriction shall be reduced so that this Agreement may be enforced in
such areas and during such period of time as shall be determined to be
reasonable.

        19. Executive represents and warrants to Employer that since
commencement of Executive's employment with Employer, Executive was not, is not
now and, in the future will not without the approval of the Board of Directors
of Employer become, under any obligation of a contractual or other nature to any
person, firm or corporation which is inconsistent or in conflict with this
Agreement, or which would prevent, limit or impair in any way the execution of
this Agreement or the performance by Executive of Executive's obligations
hereunder and Executive will indemnify and hold harmless Employer, its
Directors, officers and employees against and in respect of all liability, loss,
damage, expense or deficiency resulting from any misrepresentation, or breach of
any warranty or agreement made by Executive in connection with

                                       -5-

Executive's employment hereunder.

        20. The waiver by either party of a breach of any provision of this
Agreement shall not operate as or be construed as a waiver of any subsequent
breach thereof.

        21. Any and all notices referred to herein shall be sufficient if
furnished in writing and sent by certified mail, return receipt requested, to
the respective parties at the addresses set forth below, or such other address
as either party may from time to time designate in writing.

provisions of this Agreement shall be effective unless in writing and signed by

         WHEREAS, CERNELLE is a manufacturer of pharmaceutical products for
         commercial distribution, and


         WHEREAS,   BIGMAR  is   interested   in  entering   into  an  exclusive
         distribution and supply agreement with CERNELLE with respect to certain
         CERNELLE products,


         NOW, THEREFORE, the parties agree as follows:




         1. APPOINTMENT AS EXCLUSIVE DISTRIBUTOR

            distributor of the products, in oral dosage forms, listed in Exhibit
            A hereto,  as amended  and  revised  from time to time  ("PRODUCT").
            CERNELLE  agrees not to appoint any other person or entity to act as
            a distributor  of the PRODUCT  during the term of this Agreement and
            any renewal thereof.



<PAGE>
<PAGE>




          b) CERNELLE  shall   cooperate  fully  and  promptly  with  BIGMAR  in
             providing information and assistance necessary for BIGMAR to obtain
             Abbreviated New Drug Application  ("ANDA")  approval for PRODUCT as
             well  as any  other  private  or  public  regulatory  or  licensing
             approval,  necessary for BIGMAR, or its designee, to distribute and
             sell the PRODUCT in any country in the world.






         2. EXCLUSIVE DISTRIBUTION FEES

            omitted  and filed  separately  with the  Commission  pursuant  to a
            Request  for  Confidential  Treatment.],  payable  60 days from  the
            later of date of invoice  or  delivery  of  PRODUCT  to  BIGMAR.  At
            BlGMAR's   request,    CERNELLE   shall   provide   all   applicable
            documentation to support PRODUCT pricing cost data.


         b) CERNELLE  shall give BIGMAR 180 days  notice of any price  increases

             PRODUCT.   Individual   PRODUCT   packaging   shall   be   BlGMAR's
             responsibility, although BIGMAR may make arrangements with CERNELLE
             for CERNELLE to provide finished  packaging for individual  PRODUCT
             units on request by BIGMAR.






         4. REPRESENTATIONS AND WARRANTIES



          a) CERNELLE and BIGMAR  represent and warrant that each has full power
             and authority to enter into this Agreement, that Clas Tufvesson and
             John Tramontana  respectively are authorized to sign this Agreement
             on their  behalf and that the  execution  and  performance  of this
             Agreement will not breach or terminate any third party obligations,
             rights or licenses.


          b) CERNELLE  represents and warrants that PRODUCT is produced,  tested
             and  delivered to BIGMAR or its designee,  in accordance  with good
             manufacturing  practices ("GMP") as determined by the United States
             Food and Drug  Administration  and the specifications and standards
             set forth in United States Pharmacopoeia 23rd Edition ("USP 23") as
             amended and revised.  CERNELLE represents and warrants that PRODUCT
             may be lawfully distributed and sold by BIGMAR or its designee,  in
             every country  throughout  the world and that CERNELLE has obtained
             and shall  continue to obtain,  as  necessary  and as  requested by
             BIGMAR,  all licensing and regulatory  approvals required to permit
             the distribution and sale of PRODUCT throughout the world.







<PAGE>
<PAGE>





         c) Each party (the  "indemnifying  party") agrees to indemnify and hold
            the other  harmless  from and  against  any and all  losses,  claims
            damages or  liabilities  (including,  but not limited to  attorney's
            fees) arising from any breach of the  representations and warranties
            of the indemnifying party set forth in this Agreement.  If any claim
            arises for which one party may seek  indemnification from the other,
            the party  seeking  indemnification  shall inform the other party of
            such claim, as soon as reasonably practical.




        5. PATENTS



            Without  limiting the  provisions of Section 4, the Parties agree to
            use their best  efforts to avoid any  potential  action  against the
            importation  of PRODUCT or sale of  PRODUCT  arising  from any claim
            that the  manufacture,  sale or use of  PRODUCT  infringes  a United
            State  Patent,  including but not limited to claims which may result
            from future changes in U.S. Laws relating to U.S.  process  patents.
            BIGMAR and CERNELLE shall cooperate  promptly to attempt to identify
            any  such  patents,  and  BIGMAR  shall  obtain  the  opinion  of an
            independent outside counsel reasonably  acceptable to CERNELLE as to
            the  validity  of such  patents  and  their  potential  coverage  of
            CERNELLE manufacturing  processes. If such opinion indicates that it
            is likely that such patent will be found valid and that it is likely
            to cover  CERNELLE's  manufacture or sale of PRODUCT,  then CERNELLE
            shall use its best efforts to design  around such  patent.  CERNELLE
            agrees to indemnify BIGMAR,  for all costs,  settlements  awards and
            damages  (including  attorney  fees)  and shall  defend,  at its own
            expense,  all infringement  suits that may be brought against BIGMAR
            or  CERNELLE  on account  of the  manufacture,  use,  or sale of the
            PRODUCT.  If  CERNELLE or BIGMAR  learn that  others are  unlawfully
            infringing on patents owned or licensed by CERNELLE  which cover the
            PRODUCT,  CERNELLE  shall  diligently  prosecute any such  potential
            infringer at CERNELLE's  own cost and expense.  In  connection  with
            such suits, BIGMAR, at CERNELLE's cost and expense and at CERNELLE's
            request,  shall  cooperate  in the  prosecution  or  defense of such
            action  and  execute  such  documents  as  CERNELLE  may  reasonably
            require.

         6. FORCE MAJEURE



             Except  with  respect to the  payment of any monies due  hereunder,
             neither  party shall be liable or be in breach of any  provision of
             this  Agreement  if and to the extent  that any failure or delay on
             its part to perform any  obligation  hereunder  is because of force
             majeure or any other cause  beyond the  reasonable  control of such
             party and which  could not be avoided by the  exercise of due care,
             including,  without  limitation,  acts  of God,  earthquake,  fire,
             flood,  riots,  war,  or legal  restraints  or  actions  imposed by
             governmental or other  authorities,  provided that such party shall
             promptly  give  notice to the other party of such  occurrence,  and
             shall  promptly move to eliminate the effect  thereof to the extent
             possible and with all reasonable dispatch.





        7. TERM AND TERMINATION



          a) This Agreement shall become effective as of November 5, 1995.


          b) This Agreement shall continue for a term of fifteen (15) years from
             the date of first  commercial  sale by BIGMAR of PRODUCT  purchased
             from CERNELLE  pursuant to this Agreement.  At least six (6) months

             renewal term, of this Agreement,  as the case may be, at prices and
             on terms, for PRODUCT,  no less favorable to BIGMAR than the prices
             and terms for PRODUCT  extended by CERNELLE to any other  person or
             entity.

             Should  any  part  of  this   Agreement  be  rendered   invalid  or

             enforceability  of the  remainder,  unless  the  part  so  rendered
             invalid or  unenforceable  impairs the value of the whole Agreement

             renegotiated  between  the  parties  in such a way as to render the

1.   Disbursement / Interest Rate / Fixed Interest Commitment

     Disbursement is made at the  aforementioned  time on the condition that UBS
     is in possession of the collateral agreed upon at that time.

     If the fixed-rate mortgage is not disbursed or not disbursed in full at the
     agreed  time,  the  interest  rate shall be applied  which UBS  charges for
     fixed-rate mortgages on the same types of objects and for the same term two
     business days before disbursement of the unpaid portion.

     The interest rate applied at the time of disbursement  shall not change for
     the  duration of the fixed  interest  period  (fixed  interest  commitment)
     excepting Section 1, para 4, and Section 4, para 1 and Section 4, para 3.

     Upon payment of compensation to be calculated in accordance with Section 5,
     the Borrower may cancel the fixed-interest commitment agreed upon according
     to para 3 at any time  and  by  submitting  written  notification  to  UBS,
     Cancellation of the agreed fixed interest  commitment  shall take effect on
     the day the  corresponding  notification  is received by UBS,  Compensation
     according to Section 6 becomes due and payable at the time.

2.   Interest on Arrears

     If the mortgage interest is not paid on the  aforementioned due dates, then
     the Borrower shall be liable for the payment of interest on arrears for the
     entire period of default at a rate  determined by UBS. The rate of interest
     on arrears shall not be more than 2% above the interest rate charged at the
     time by UBS for new  first-ranking  adjustable-rate  mortgages  on the same
     types of object.

3.   Conditions  after  Expiry  of the  Fixed-Interest  Period  and  upon  Early
     Cancellation of the Fixed-Income Commitment

     After expiry of the  fixed-interest  period  agreed upon of after the early
     cancellation  of the fixed  interest  commitment  agreed upon in accordance
     with  Section  1, Para 4;  Section  4, Para 1, or  Section  4, Para 3, this
     fixed-interest  mortgage  shall be  maintained at the same  conditions  for
     adjustable-rate  mortgages then applied by UBS to new mortgages on the same
     types of object,  provided  no  agreement  stipulating  otherwise  has been
     concluded between the Borrower and UBS.

     With regard to the interest rate to be applied after expiry of  the  fixed-
     interest  period   or after  the early   cancellation of the fixed-interest
     commitment agreed  upon,  UBS reserves the  right to change  this  interest
     rate at any time subject to the advance notice, interest rate changes shall
     go into effect on the dates cited in the respective notices.

4.   Notice

     Upon  observance  of a six-month  period of notice,  the  Borrower may give
     notice of this mortgage at any time against payment of a compensation to be
     calculated  in  accordance  with Section 5. The  fixed-interest  commitment
     shall also be considered canceled upon receipt of the notice at UBS.

     Upon observance of a six-month period of notice, UBS may give notice of the
     mortgage only at the end of the fixed-interest  period agreed upon, subject
     to the conditions in Section 4, Para 3.

     Upon observance of a six-month  period of notice,  UBS shall be entitled to
     give notice of the fixed-rate  mortgage if the Borrower  violates the terms
     of the Mortgage Agreement;  in particular,  if the Borrower is more than 30
     (thirty) days in arrears with an interest payment; or if, in the opinion of
     UBS, the property/properties  pledged as collateral for this fixed-interest
     mortgage  declines/decline  in  value  or  does/do  not  otherwise  provide
     adequate  cover.  Cancellation  of the agreed fixed  commitment  shall take
     effect on the second day after  dispatch of notice in writing by UBS to the
     last-known address of the Borrower.

     If  notice  becomes  effective prior to the expiry  of  the  fixed-interest
     period agreed upon, the Borrower shall pay  compensation  to  be calculated
     in accordance with Section 6 and becomes due  and payable at  the  time the
     interest rate commitment agreed upon is canceled.

5.   Repayment in the event of Transfer of Ownership or Sale in connection  with
     Foreclosure Proceedings

     If the  object(s)  pledged  is/are sold  privately  or in  connection  with
     foreclosure proceedings,  the entire fixed-rate mortgage, including accrued
     interest,  shall  become  due  for  immediate  repayment  on the day of the
     transfer of  ownership  or on the day of the public  auction.  In the event
     repayment  becomes due during the fixed  interest  period agreed upon,  the
     Borrower  must pay the Bank  compensation  to be  calculated  according  to
     Section 6 payable as of the same date.

6.   Compensation

     The  amount  of the  compensation  payable  by the  Borrower  to UBS as per
     Section 1, para 4, Section 4, para 4 and Section 5 shall be  equivalent  to
     the difference between the interest rate contractually  agreed upon for the
     fixed-interest  mortgage and the rate at the time the compensation  becomes
     due for money or capital market  investments  (reference  rate:  Euro money
     market rate) with a maturity  corresponding  to the (remaining) time of the
     fixed-interest  period;  this rate is  calculated  as a  percentage  of the
     borrowed principal pro rata temporis for the duration of the fixed-interest
     period agreed upon or for the remaining time of the fixed-interest  period.
     Upon request, UBS will provide the Borrower with a corresponding offer.

7.   Joint and Several Liability / Cumulative Debt Assumption

     If there are  several  borrowers,  they shall share  joint  liability.  The
     borrower(s)  not mentioned in the mortgage  note(s)  and/or bearer  bond(s)
     shall hereby assume  cumulatively  and jointly the debt(s) arising from the
     aforementioned  mortgage note(s) and/or bearer bond(s), whose ownership has
     been assigned to UBS as security.

8.   Fire Insurance and Insurance for Damages by Natural Forces

     The Borrower is obliged to insure the property and all appurtenances on the
     mortgaged  land  against fire and damage by natural  forces,  either with a
     state-controlled  insurance company or an insurance  company  domiciled  in
     Switzerland,  for an  insurance  sum  deemed by UBS to be  sufficient.  The
     policy and premium receipts are to be submitted to UBS should the latter so
     request.

9.   General Conditions

     In addition,  the General  Conditions  of UBS shall apply.  A copy of these
     General  Conditions  has been received by the  Borrower,  who confirms that
     he/she has read them and accepts them without reservation.

      part. 3208 RFD Couvet (NE)

  2.  The  mortgage  note(s) as  cited  in Paragraph  1 above  and  whose ownership  is  to be  transferred/has been
      transferred to UBS shall provide  UBS with security for all  claims against the Borrower/Pledger arising  from
      agreements  already concluded with UBS  or from agreements to  be concluded in the  future with UBS within the
      framework of existing business relations, including all interest  due and accrued  and commissions as well  as
      the related court or out-of-court fees and expenses.

      The  mortgage note(s) whose ownership has  been transferred to one office of  UBS shall also serve as security
      for the claims of  other UBS offices.  In the event  of several claims,  UBS shall determine  to which of  the
      claims  the mortgage note(s) whose ownership  has been transferred to UBS  or the proceeds from its/their sale
      shall be charged.

  3.  The parties agree that,  in place of the  secured claims as cited  in Paragraph 2 above,  UBS may enforce  the
      mortgage  note claim(s) arising  from the mortgage  note(s) as cited in  Paragraph 1 above  in addition to the
      annual interest due for three years and the accrued interest at 10% p.a. in each case (interest payment dates:
      June  30/December  31),  for  which  the   Borrower/Pledger  expressly  acknowledges  herewith  his   personal
      indebtedness.

      Contrary to any agreement regarding  the period(s) and date(s)  of notice in the  mortgage note(s) as cited in
      Paragraph 1 above, UBS may enforce the mortgage note  claim(s) under the same conditions as those applying  to
      the  secured  claim(s) as  cited in  Paragraph  2 above.  No special notice of the  mortgage note  claim(s) is
      necessary. UBS  may  freely or  by  legal enforcement  sell  the mortgage  note(s)  whose ownership  has  been
      transferred to UBS as cited in Paragraph 1 without observing the formalities stated in the Federal Law on Debt
      Collection and Bankruptcy.

      On  the other hand, UBS shall also  be authorized to enforce the secured  claims as cited in Paragraph 2 above
      prior to the sale of the  mortgage note(s) whose ownership has  been transferred to UBS. The  Borrower/Pledger
      hereby  expressly waive the right to protest the advance sale of the mortgage note(s) whose ownership has been
      transferred to UBS as security as cited in Paragraph 1 above.

  4.  In the event  of mortgage  note increases,  this Agreement shall  also apply  to the  increased mortgage  note
      claim(s).

  5.  If,  in the case of a change of ownership in the mortgaged property/properties, the new owner assumes the debt
      secured by this property/these properties as cited in Paragraph 2 in addition to the mortgage note debt(s)  as
      cited  in Paragraph 1 above, UBS shall be entitled  to transfer this Agreement with all rights and obligations
      to the new owner.

  6.  When UBS no  longer possesses  any claims  whatsoever against  the Borrower/Pledge,  UBS shall  be obliged  to
      transfer  the ownership of the mortgage note(s) as cited in Paragraph 1 above back to the Borrower/Pledger, if
      UBS is satisfied in  respect of its claims  by a guarantor or  any other third party  (e.g. an assignee).  UBS
      shall be entitled but not obliged to transfer the mortgage note(s) to the guarantor or other third party.

  7.  In  addition, the General Conditions of UBS shall also apply, whereby the Borrower/Pledger declare that he has
      received said Conditions, is cognizant of their contents and expressly state his acceptance of them by signing
      this Agreement.

GENERAL CONDITIONS
 
<TABLE>
<S>   <C>
      The following conditions are intended to clearly regulate the relations between the bank and its customers.
 
1     POWER  OF DISPOSITION  The signatures and signing powers given in writing to the bank are alone valid insofar
      as the bank is concerned until cancelled in writing, notwithstanding entries to the contrary in the  Register
      of Commerce or other media of public notice.

2     OBJECTIONS  OF THE CUSTOMER  Any objection by the  customer relating to the execution or non-execution of any
      order of any  kind as  well as any  objection to  any statement of  account or  of deposit, or  to any  other
      communication,  must be made promptly upon receipt of  the respective communication, but at the latest within
      the time  specified by  the bank;  otherwise the  execution or  non-execution of  the order  as well  as  the
      pertinent  statements and  communications are deemed  to have  been approved. In  case of  non-receipt of any
      communication the customer must make his complaint at the time when he should have received the communication
      in the ordinary course of business.

3     COMMUNICATIONS OF THE BANK  Communications of the bank are deemed to have been made if dispatched to the last
      address notified by the customer. The date indicated on the copy or on the mailing records in the  possession
      of  the bank is presumed to be the mailing date. Mail which  is to be kept on deposit at the bank is, in case
      of doubt, considered to have been delivered on the date it bears.

4     VERIFICATION OF THE SIGNATURES AND THE LEGITIMATION  Any damage resulting from reliance by the bank upon  any
      false,  forged, altered or  otherwise legally insufficient instructions,  documentation or other legitimation
      shall be borne by the customer, unless the bank is guilty of gross negligence.

5     LEGAL INCAPACITY  Any  damage resulting from legal  incapacity of the  customer or of a  third party must  be
      borne by the customer, unless such incapacity has been published in an official journal in Switzerland in the
      case of the customer himself or has been communicated to the bank in writing in the case of a third party.

6     ERRORS  IN TRANSMISSION  Any damage resulting from the  use of the mails, telegraph, telephone, telex, of any
      other system of communication or means of transportation, especially from losses, delays,  misunderstandings,
      mutilations or duplicates, must be borne by the customer, unless the bank is guilty of gross negligence.

7     NON-EXECUTION  OR BELATED EXECUTION OF ORDERS  In case of damage due to non-execution or belated execution of
      orders (stock exchange orders  excluded), the bank  is liable only for  the loss of  interest, unless in  the
      particular case it has been warned of the imminent risk of more extensive damages.

8     RIGHT  OF PLEDGE AND RIGHT OF COMPENSATION  With respect to all aspects which it holds in custody for account
      of the customer, either at its own offices or elsewhere, the bank has a lien for all its unliquidated  claims
      originating  in  the banking  relationship irrespective  of maturity  or  currency and  a right  to immediate
      compensation for all  liquidated claims.  However, the  lien becomes  effective only  at the  time the  claim
      arises.  This rule applies  equally to credits  and to loans  with or without  guarantees or securities. Upon
      default of performance on the part of the customer, the bank may, in its discretion, realize upon the pledges
      by formal proceedings or by private arrangements.

9     CURRENT ACCOUNT  RELATIONS   The  bank  credits and  debts  interest, commissions  and  fees agreed  upon  or
      customary, as well as taxes, at its choice, quarterly, semi-annually or annually. The bank reserves the right
      to modify its rates of  commissions and interest at  any time, in particular if  the conditions of the  money
      market  have changed, and to  inform the customer of  any modification by circular  letter, by posters in the
      lobby or in any other appropriate way. In the absence of presented objection within one month, the statements
      of account issued by  the bank are deemed  to have been  approved, even if the  confirmation statement to  be
      signed by the customer has not been received back by the bank. The express or tacit approval of the statement
      of  account includes the approval  of all items, as  well as possible reservations  of the bank, contained in
      this statement.

      If the  customer has given  several different orders  the total amount  of which exceeds  the credit  balance
      available  of  the  credit  granted to him,  the  bank is entitled to decide in its  discretion  and  without
      consideration to the dates of the times of reception, which of the dispositions it wants to execute  entirely
      or partly.

10    ACCOUNTS IN FOREIGN CURRENCIES  The bank's assets corresponding to the customer's credits in foreign currency
      are held in the same  currency in or outside  of the country whose currency  is involved. The customer  bears
      proportionately  to his share all the economic and legal consequences which, as a result of measures taken by
      the country concerned, affect all the  bank's assets in the country of  the currency or in the country  where
      the funds are invested.
      The  obligations of the bank arising  from accounts in foreign currencies  shall be discharged exclusively at
      the business office of the bank holding the accounts  and solely through the establishment of a credit  entry
      in  the country  of the  currency at  the bank's  own branch,  a correspondent  bank or  a bank  named by the
      customer.
      In the case  of current  accounts in foreign  currencies, the  counterpart is placed  in the  country of  the
      respective currency.

11    CREDITING AND DEBITING PAYMENTS IN FOREIGN CURRENCIES  Amounts in foreign currencies are credited and debited
      in  Swiss francs, unless  the customer has  given proper instructions  to the contrary  or is a  holder of an
      account in the foreign currency in question. If the customer maintains accounts in other currencies only, the
      bank is free to credit or debit the customer's accounts in one of these currencies.

12    BILLS OF EXCHANGE, CHECKS AND OTHER  INSTRUMENTS  The bank is entitled  to redebit unpaid bills of  exchange,
      checks  and other papers  which had been  discounted or credited.  Nevertheless, until the  settlement of any
      debit balance credited by any such  redebit, the bank retains against the  world the right to claims  arising
      out  of the Law of  Bills of Exchange or  the Check Law  or  otherwise for payment of  the full amount of the
      bills of exchange of the checks  and of all other instruments as  well as accessory claims against  everybody
      liable on the paper.

13    TERMINATION  OF THE BUSINESS RELATIONSHIP  The bank  reserves the right to cancel any business relationships,
      in particular credits which  have been promised or  used, with immediate effect,  in which case any  possible
      claims  of the bank  will fall immediately  due for repayment.  Agreements in writing  to the contrary remain
      reserved.

14    SATURDAYS AS LEGAL HOLIDAYS   For all  business relations with  the bank, Saturdays  are equivalent to  legal
      holidays.

15    LAW  GOVERNING THE LEGAL RELATIONSHIP BETWEEN THE BANK AND ITS  CUSTOMERS AND PLACE TO SUE  All legal aspects
      of the  relationship between  the client  and bank  shall  be governed  exclusively by  Swiss law.  Place  of
      performance  of all obligations of  both parties, as well  as the exclusive jurisdiction  of lawsuits and any
      other kinds of legal  proceedings shall be the  domicile of the  business office of the  bank with which  the
      contractual  relationship exists. Excepting only that  the bank may sue the  client in any competent court at
      the domicile of the client or any other court having jurisdiction.

16    RESERVATION OF SPECIAL  REGULATIONS  Certain  kinds of  transactions are, besides  these General  Conditions,
      subject  to  special regulations  issued by  the bank.  In particular,  the deposit  of securities  and other
      valuables for safe custody  (custodianship), savings books  and savings accounts,  deposit books and  deposit
      accounts, checkbooks, safe deposit boxes and night depositories.  Moreover, stock exchange  transactions  are
      subject  to the local rules, documentary transactions  to the Uniform  Customs  and  Practice  for Commercial
      Documentary  Credits  issued  by  the  International  Chamber  of  Commerce, and collecting  and  discounting
      transactions to the general terms issued by the Association of Swiss Bankers.

17    MODIFICATIONS  OF THE GENERAL CONDITIONS  The bank reserves the right to modify the General Conditions at any
      time.  The customer will be  informed of these modifications  by circular letter or  in any other appropriate
      way, and in the absence of objection within a month the modifications are deemed to have been approved.

Union Bank of Switzerland

SURETY INSTRUMENT

The undersigned CHEMHOLDING S.A. Barbengo

declares that it institutes  itself as sole co-surety  towards the Union Bank of
Switzerland for the  reimbursement of any credit extended by the bank now, or in
the future, to

Bigmar Pharmaceuticals SA, Barbengo

whether  such  credits  arise  from  business  or legal  relationships,  or from
contractual and legal interests,  concerning  annuities,  commissions,  etc., as
well as for reimbursement of the amounts and expenses referred to in Art. 499 of
the Code of  Obligations,  even if the latter are added to the  principal at the
time of the  regular  closing of the  current  accounts,  up to the amount of SF
1,700,000 (in letters: Swiss Francs one million seven hundred thousand).

[Deleted paragraph]

The reduction of the amount of the surety set forth in the law,  whether  caused
by an annual  reduction,  or as a consequence  of the reduction of the principal
debt,  is expressly  excluded  for the entire term of the business  relationship
between the bank and the customer, even if the credit granted by the bank to the
main debtor is  temporarily  reimbursed,  or if it needs to remain  unused for a
certain period of time, or if it is used only in part.
         
Whenever the bank enjoys other guaranties not expressly  instituted to cover the
debt  guaranteed  by the surety,  the bank is entitled to use them first for the
reimbursement of other credits.
       
[Deleted paragraph]

At the  maturity of the  principal  debt,  the bank may take action  against the
co-surety before selling off existing chattels, if any.

If,  due to the fact  that it is  domiciled  abroad or that it  transferred  its
domicile   abroad,  the principal  debtor cannot cover its  obligations,  or can
cover them only partially, due to foreign legal provisions,  such as for example
in  matters  of  compensation  movements,  or  prohibition  of  transfers,   the
undersigned  surety  still  guarantees  the  original  total  commitment  of the

     shall be obligated to transfer back to the  debtor/transferror the mortgage

     third partiee (for example,  the  transferror),  it is authorized,  but not
     obligated,  to transmit the mortgage  certificate(s)  to the surety or such
     third party.

       Schweizeriache Bankgesellschaft
       Unione di Banche Svizzere
       Union Bank of Switzerland
- --------------------------------------


- ------------------
General Conditions
- ------------------

 
The  following conditions are intended to clearly regulate the relations between
the bank and its customers.
 
1. Power of Disposition. The signatures  and signing powers given in writing  to
the  bank are alone valid  insofar as  the bank  is concerned until cancelled in
writing, notwithstanding entries to the contrary in the Register of Commerce  or
other media of public notice.
 
2.  Objections of the  Customer. Any objection  by the customer  relating to the
execution or non-execution of any order of any kind as well as any objection  to
any statement of account or  of deposit, or to  any other communication, must be
made promptly upon receipt of the  respective  communication,  but at the latest
within the time  specified by the bank, otherwise the execution or non-execution
of the order as  well as the pertinent  statements and communications are deemed
to have been approved. In case of  non-receipt of any communication the customer
must  make  his  complaint  as  the  time  when  he  should  have  received  the
communication in the ordinary course of business.
 
3. Communications of  the Bank. Communications  of the bank  are deemed to  have
been  made if dispatched to the last  address notified by the customer. The date
indicated on the copy or on the mailing records in the possession of the bank is
presumed  to be the  mailing date. Mail  which is to  be kept on  deposit at the
bank  is,  in  case of doubt,  considered to have been  delivered on the date it
bears.
 
4. Verification of the Signatures  and the  Legitimation. Any  damage  resulting
from  reliance by the bank  upon any false, forged, altered or otherwise legally
insufficient instructions, documentation or other legitimation shall be borne by
the customer, unless the bank is guilty of gross negligence.
 
5. Legal Incapacity. Any damage resulting from legal incapacity of the  customer
or  of a third party  must be borne by the  customer, unless such incapacity has
been published in an official journal in Switzerland in the case of the customer
himself or has been communicated to the bank in writing  in the case of a  third
party.
 
6.  Errors in  Transmission. Any  damage resulting  from the  use of  the mails,
telegraph, telephone, telex, or  any other system of  communication or means  of
transportation,  especially from losses,  delays, misunderstandings, mutilations
or duplication, must be borne by the customer unless the bank is guilty of gross
negligence.

7. Non-execution  or Delayed  Execution of  Orders.  In case  of damage  due  to
non-execution  or delayed execution of  orders (stock exchange orders excluded),
the bank is liable only for the loss of interest, unless in the particular  case
it has been warned of the imminent risk of more extensive damages.
 
8.  Right of Pledge and Right of  Compensation. With respect to all assets which
it holds in custody  for account of  the customer either at  its own offices  or
elsewhere,  the bank has a  lien for all its  unliquidated claims originating in
the banking relationship  irrespective of maturity  or currency and  a right  to
immediate  compensation  for all  liquidated  claims. However, the  lien becomes
effective only  at the  time the  claim  arises. This  rule applies  equally  to
credits  and to loans with or without  guarantees or securities. Upon default of
performance on  the part  of the  customer,  the bank  may, in  its  discretion,
realize upon the pledges by formal proceedings or by private arrangements.

9.  Current Account Relations. The bank credits and debits interest, commissions
and fees agreed upon or customary, as  well as taxes, at its choice,  quarterly,
semi-annually  or annually. The bank  reserves the right to  modify its rates or
commissions  and  interest  at any time, in particular if the conditions of  the
money  market have changed,  and to inform  the customer of  any modification by
circular letter, by posters in the lobby or in any other appropriate way. In the
absence of  presented objection  within  one month,  the statements  of  account
issued  by the bank are  deemed to have been  approved, even if the confirmation
statement to be signed by the customer  has not been received back by the  bank.
The  express or tacit approval of the statement of account includes the approval
of all items, as well as of possible reservations of the bank contained in  this
statement.
 
If  the customer has  given several different  orders the total  amount of which
exceeds the credit balance available or the  credit granted to him, the bank  is
entitled to decide  in its discretion and without consideration  to the dates or
the  times of  reception, which of the dispositions it wants to execute entirely
or partly.
 
10. Accounts  in Foreign  Currencies.  The bank's  assets corresponding  to  the
customer's  credits in  foreign currency  are held  in the  same currency  in or
outside  of  the  country  whose  currency  is  involved.  The  customer   bears
proportionately to his share all the economic and legal consequences which, as a
result  of measures taken by the country concerned, effect all the bank's assets
in the country of the currency or in the country where the funds are invested.
 
The obligations of the bank arising from accounts in foreign currencies shall be
discharged exclusively at the business office  of the bank holding the  accounts
and  solely through the  establishment of a  credit entry in  the country of the
currency at the bank's own branch, a  correspondent bank or a bank named by  the
customer.
 
In the case of current accounts in foreign currencies, the counterpart is placed
in the country of the respective currency.
 
11.  Crediting and Debiting  Payments in Foreign  Currencies. Amounts in foreign
currencies are credited  and debited in  Swiss francs, unless  the customer  has
given  proper instructions to the  contrary or is a holder  of an account in the
foreign currency  in  question. If  the  customer maintains  accounts  in  other
currencies only, the bank is free to  credit or debit the customer's accounts in
one of these currencies.
 
12. Bills of  Exchange, Checks and  Other Instruments. The  bank is entitled  to
redebit  unpaid  bills  of exchange,  checks  and  other papers  which  had been
disecured or credited.  Nevertheless, until the settlement of any debit  balance
created  by any such  redebit, the bank  retains against the  world the right to
claims arising out of the law of Bills of Exchange or the Check Law or otherwise
for payment of the full amount of the bills of exchange of the checks and of all
other instruments as well  as accessory claims against  everybody liable on  the
paper.
 
13.  Termination of  the Business Relationship.  The bank reserves  the right to
cancel any  business  relationships,  in  particular  credits  which  have  been
promised  or used, with immediate  effect, in which case  any possible claims of
the bank will fall immediately due  for repayment. Agreements in writing to  the
contrary remain reserved.
 
14.  Saturdays  or Legal  Holidays. For  all business  relations with  the bank,
Saturdays are equivalent to legal holidays.
 
15. Law Governing the Legal Relationship between the Bank and its Customers  and
Place  to Save. All  legal aspects of  the relationship between  client and bank
shall be  governed  exclusively  by  Swiss law.  Place  of  performance  of  all
obligations  of both parties, as well  as the exclusive jurisdiction of lawsuits
and any other kinds of legal proceedings  shall be the domicile of the  business
office  of the  bank with which  the contractual  relationship exists. Excepting
only that the bank may sue the client in any competent court at the domicile  of
the client or any other court having jurisdiction.
 
16.  Reservation  of Special  Regulations.  Certain kinds  of  transactions are,
besides these General Conditions, subject  to special regulations issued by  the
bank.  In  particular, the  deposit of securities and  other valuables  for safe
custody (custodianship), savings books and  savings accounts, deposit books  and
deposit  accounts,  checkbooks,  safe  deposit  boxes  and  night  depositories.
Moreover,  stock  exchange  transactions  are   subject  to  the  local   rules,
documentary  transactions  to  the  Uniform Customs and  Practice for Commercial
Documentary Credits  issued  by  the  International  Chamber  of  Commerce,  and
collecting  and  discounting transactions  to the  general  terms issued  by the
Association of Swiss Bankers.
 
17. Modifications of  the General  Conditions. The  bank reserves  the right  to
modify  the General  Conditions at  any time. The  customer will  be informed of
these modifications by circular letter or  in any other appropriate way, and  in
the  absence of objection  within a month  the modifications are  deemed to have
been approved.

                              DIRECTOR OPTION PLAN

1.       PURPOSE

         The purpose of the Director Option Plan (the "Plan") of Bigmar, Inc., a
Delaware corporation (the "Company"), is to encourage ownership in the Company
by outside directors of the Company whose continued services are considered
essential to the Company's future progress and to provide them with a further
incentive to remain as directors of the Company.

2.       ADMINISTRATION

         The Compensation and Stock Option Committee of the Company's Board of
Directors (the "Committee") shall supervise and administer the Plan. Grants of
stock options under the Plan and the amount and nature of the awards to be
granted shall be automatic and non-discretionary in accordance with Section 5.
However, all questions of interpretation of the Plan or of any options issued
under it shall be determined by the Committee and such determination shall be
final and binding upon all persons having an interest in the Plan.

3.       DIRECTORS ELIGIBLE FOR PARTICIPATION

         Each director of the Company who is not an employee of, or consultant
to, the Company or any subsidiary or affiliate of the Company shall be
eligible to participate in the Plan.

4.       STOCK SUBJECT TO THE PLAN


         (a)      The maximum number of common shares which may be issued under
                  the Plan shall be fifty thousand (50,000) shares of common
                  stock, par value $.001 of the Company ("Common Stock").

         (b)      If any outstanding option under the Plan for any reason
                  expires or is terminated without having been exercised in
                  full, the Common Stock allocable to the unexercised portion of
                  such option shall again become available for grant pursuant to
                  the plan.

5.       TERMS, CONDITIONS AND FORM OF OPTIONS

         Each option granted under the Plan shall be evidenced by a written
agreement in such form as the Committee shall from time to time approve, which
agreements shall comply with and be subject to the following terms and
conditions:

         (a)      Option Grant Dates. Each eligible director, including a
                  director serving in that capacity on the effective date of the
                  Plan, will automatically receive an option

<PAGE>
<PAGE>
                  to purchase three thousand (3,000) shares of Common Stock on
                  the effective date of the Plan. Thereafter, an option to
                  purchase one thousand five hundred (1,500) shares of Common
                  Stock shall be granted on the date of each regular annual
                  meeting of the stockholders of the Company to each eligible
                  director who either is continuing as a director subsequent to
                  the meeting or who is elected at such meeting to serve as a
                  director. All options granted under the Plan will be
                  immediately exercisable.

         (b)      Option Exercise Price. The option exercise price per share of
                  Common Stock for each option granted under the Plan shall be
                  determined by the Committee provided that such price shall not
                  be less than the fair market value of the Common Stock on the
                  date of the grant. For the purposes hereof, the term "fair
                  market value" shall mean the fair market value as determined
                  in good faith by the Committee.

         (c)      Options Non-Transferable. Each option granted under the Plan
                  by its terms shall not be transferable by the optionee
                  otherwise than by will, or by the laws of descent and
                  distribution, or pursuant to a qualified domestic relations
                  order (as defined in Section 414(p) of the United States
                  Internal Revenue Code (the "Code")), and shall be exercised
                  during the lifetime of the optionee only by him. No option or
                  interest therein may be transferred, assigned, pledged or
                  hypothecated by the optionee during his lifetime, whether by
                  operation of law or otherwise, or be made subject to
                  execution, attachment or similar process.

         (d)      Exercise Period. Except as otherwise provided in the plan,
                  each option may be exercised fully on the date of grant of
                  such option, provided that, subject to the provisions of
                  Section 5(e), no option may be exercised more than ninety (90)
                  days after the optionee ceases to serve as a director of the
                  Company. No option shall be exercisable after the expiration
                  of ten (10) years from the date of grant or prior to approval
                  of the Plan by the stockholders of the Company, whichever is
                  earlier.

         (e)      Exercise Period Upon Disability or Death. Notwithstanding the
                  provisions of Section 5(d), any option granted under the Plan:

                  (i)      may be exercised in full by an optionee who becomes
                           disabled (within the meaning of Section 22(e)(3) of
                           the Code or any successor provision thereof) while
                           serving as a director of the Company; or

                  (ii)     may be exercised

                           (A)      in full upon the death of an optionee while
                                    serving as a director of the Company, or


                                       -2-
<PAGE>

<PAGE>

                           (B)      to the extent when exercisable upon the
                                    death of an optionee within ninety (90) days
                                    of ceasing to serve as a director of the
                                    Company,

                           by the person to whom it is transferred by will, by
                           the laws of descent and distribution or by written
                           notice filed pursuant to Section 5(h);

                  in each such case within the period of one year after the date
                  the optionee ceases to be such a director; provided, that no
                  option shall be exercisable after the expiration of ten (10)
                  years from the date of grant.

         (f)      Exercise Procedure. Options may be exercised only by written
                  notice to the Company at its principal office accompanied by
                  payment of the full consideration for the Common Stock as to
                  which they are exercised.

         (g)      Payment of Purchase Price. Options granted under the Plan may
                  provide for the payment of the exercise price (i) by delivery
                  of cash or a check to the order of the Company in an amount
                  equal to the exercise price of such options or, (ii) to the
                  extent provided in the applicable option agreement, by
                  delivery to the Company of Common Stock then owned by the
                  optionee having a fair market value equal in amount to the
                  exercise price of the Options being exercised, or (iii) by
                  any combination of such methods of payment. The fair market
                  value of any Common Stock or other non-cash consideration
                  which may be delivered upon exercise of an option shall be
                  determined by the Committee.

         (h)      Exercise of Representative Following Death of Director. A
                  director, by written notice to the Company, may designate
                  one or more persons (and from time to time change such
                  designation) including his legal representative, who, by
                  reason of his death, shall acquire the right to exercise all
                  or a portion of the option. If the person or persons so
                  designated wish to exercise any portion of the option, they
                  must do so within the term of the option as provided herein.
                  Any exercise by a representative shall be subject to the
                  provisions of the Plan.

6.       ASSIGNMENTS

         The rights and benefits under the Plan may not be assigned except for
the designation of a beneficiary as provided in Section 5.

7.       LIMITATION OF RIGHTS

         (a)      No Right to Continue as a Director. Neither the Plan nor the
                  granting of an option nor any other action taken pursuant to
                  the Plan, shall constitute or be evidence of any agreement or
                  understanding, express or implied, that the Company will
                  retain a director for any period of time.

                                       -3-

<PAGE>



         (b)      No Stockholders' Rights for Options. An optionee shall have no
                  rights as a stockholder with respect to the Common Stock
                  covered by his options until the date of the issuance to him
                  of a share certificate therefor, and no adjustment will be
                  made for dividends or other rights for which the record date
                  is prior to the date such certificate is issued.

8.       CHANGES IN CAPITAL STOCK

         (a)      If (x) the outstanding shares of Common Stock are increased,
                  decreased or exchanged for a different number or kind of share
                  or other security of Company, or (y) additional shares of
                  Common Stock or new or different shares of Common Stock or
                  other securities of the Company or other non-cash assets are
                  distributed with respect to such shares or other securities,
                  through or as a result of any merger, consolidation, sale of
                  all or substantially all of the assets of the Company,
                  reorganization, recapitalization, reclassification, stock
                  dividend, stock split, reverse stock split or other similar
                  transaction with respect to such shares or other securities,
                  an appropriate and proportionate adjustment shall be made in
                  (i) the maximum number and kind of shares reserved for
                  issuance under the Plan, and (ii) the number and kind of
                  shares or other securities subject to then outstanding
                  options under the Plan and (iii) the price for each share
                  subject to any then outstanding options under the Plan,
                  without changing the aggregate purchase price as to which such
                  options remain exercisable. No fractional shares will be
                  issued under the Plan on account of any such adjustments.
                  Notwithstanding the foregoing, no adjustment shall be made
                  pursuant to this Section 8 if such adjustment would cause the
                  Plan to fail to comply with Rule 16b-3 or any successor rule
                  promulgated pursuant to Section 16 of the Securities Exchange
                  Act of 1934, as amended.

         (b)      In the event that the Company is merged or consolidated into
                  or with another corporation (in which consolidation or merger,
                  the stockholders of the Company receive distributions of cash
                  or securities of another issuer as a result thereof), or in
                  the event that all or substantially all of the assets of the
                  Company are acquired by any other person or entity, or in the
                  event of a reorganization or liquidation of the Company, the
                  Board of Directors of the Company, or the board of directors
                  of any corporation assuming the obligations of the Company,
                  shall, as to outstanding options take one or more of the
                  following actions: (i) provide that such options shall be
                  assumed, or equivalent options shall be substituted, by the
                  acquiring or succeeding corporation (or an affiliate thereof),
                  (ii) upon written notice to the optionee, provide that all
                  unexercised options will terminate immediately prior to the
                  consummation of such transaction unless exercised by the
                  optionee within a specified period following the date of such
                  notice, or (iii) if, under the terms of a merger transaction,
                  holders of the Common Stock will receive upon consummation
                  thereof a cash payment for each share surrendered in the
                  merger (the "Merger Price"), make or pro-

                                       -4-
<PAGE>

<PAGE>

                  vide for a cash payment to the optionees equal to the
                  difference between (A) the Merger Price times the number of
                  shares of Common Stock subject to such outstanding options (to
                  the extent then exercisable at prices not in excess of the
                  Merger Price) and (B) the aggregate exercise price of all such
                  outstanding options in exchange for the termination of such
                  options.

9.       AMENDMENT OF THE PLAN

         The Committee may suspend or discontinue the Plan or review or amend it
in any respect whatsoever; provided, however, that without approval of the
stockholders of the Company no revision or amendment shall change the number of
shares subject to the Plan or the number of shares issuable to any director of
the Company under the Plan (except as provided in Section 8), change the
designation of the class of directors eligible to receive options, or materially
increase the benefits accruing to participants under the Plan, and further
provided, that no amendment to the number of shares of Common Stock issuable to
any director shall be effected more than once in any six month period.

10.      WITHHOLDING

         The Company shall have the right to deduct from payments of any kind
otherwise due to the optionee, any federal, state or local taxes of any kind
required by law to be withheld with respect to any shares issued upon exercise
of options under the Plan.

11.      EFFECTIVE DATE AND DURATION OF THE PLAN

         (a)      Effective Date. The Plan shall become effective when adopted
                  by the Board of Directors of the Company and approved by the
                  Company's stockholders. Amendments to the plan not requiring
                  stockholder approval shall become effective when adopted by
                  the Committee; amendments requiring stockholder approval shall
                  become effective when adopted by the Committee, but no option
                  granted after the date of such amendment shall become
                  exercisable (to the extent that such amendment to the Plan was
                  required to enable the Company to grant such option to a
                  particular optionee) unless and until such amendment shall
                  have been approved by the Company's stockholders. If such
                  stockholder approval is not obtained within six months of the
                  Committee's adoption of such amendment, any options granted on
                  or after the date of such amendment shall terminate to the
                  extent that such amendment to the Plan was required to enable
                  the Company to grant such option to a particular optionee.

         (b)      Termination. Unless sooner terminated by the Committee, the
                  Plan shall terminate upon the date on which all shares
                  available for issuance under the Plan shall have been issued
                  pursuant to the exercise or cancellation of options granted
                  under the Plan.

12.      NOTICE:

         Any written notice to the Company required by any of the provisions of
the Plan shall be addressed to the Secretary of the Company and shall become
effective when it is received.

13.      GOVERNMENTAL REGULATION

         The Company's obligation to sell and deliver shares of Common Stock
under the plan is subject to the approval of or requirements of any governmental
authority applicable in connection with the authorization issuance or sale of
such shares.

14.      COMPLIANCE WITH RULE 16b-3

         Transactions under the Plan are intended to comply with all applicable
conditions of Rule 16b-3 or its successor promulgated pursuant to Section 16 of
the Securities Exchange Act of 1934, as amended. To the extent any provision of
the Plan or action by the Committee in administering the plan fails to so
comply, it shall be deemed null and void, to the extent permitted by law and
deemed advisable by the Committee.

15.      GOVERNING LAW

         The Plan and all determinations made and actions taken pursuant hereto
shall be governed by the laws of the State of Delaware and the laws of the
United States applicable therein.

16.      SUCCESSORS AND ASSIGNS

         This Plan shall inure to the benefit of and be binding upon each
successor and assign of the Company. All obligations imposed upon an optionee,
and all rights granted to the Company hereunder, shall be binding upon the
optionee's heirs, legal representatives and successors.

17.      ENTIRE AGREEMENT

         This Plan and the written agreement with respect to each option granted
under this Plan constitute the entire agreement with respect to the subject
matter hereof and thereof, provided that in the event of any inconsistency
between the Plan and such written agreement, the terms and conditions of this
Plan shall control.
