                                  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  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 2,000,937 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 350,313 shares  of Common Stock of  the Company. See 'The  Company'
and 'Certain Transactions.'
    
 
     Unless  the context indicates otherwise, the term 'Company' as used in this
Prospectus refers to the Company and its subsidiaries as a whole. The  Company's
principal  executive offices  are located  at 6660  Doubletree Avenue, Columbus,
Ohio 43229, and its telephone number is (614) 848-8380.

                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.

                                  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  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.  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  of the board  of
Cernelle  and a director of Chemholding. Chemholding, a principal stockholder of
the
 
                                       8
 
<PAGE>
<PAGE>
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 76% of the Company's total
sales. For  the  three  months  ended March  31,  1996,  these  sales  comprised
approximately  73% 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 allow others to enter into arrangements with the Company's
collaborators for the commercialization of
    
 
                                       9
 
<PAGE>
<PAGE>
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 69% 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.  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 have a material adverse
effect  on the Company and its prospects.  In addition, the market acceptance of
    
 
                                       10
 
<PAGE>
<PAGE>
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.
    
 
   
     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,  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 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
    
 
                                       11
 
<PAGE>
<PAGE>
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  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
    
 
                                       12
 
<PAGE>
<PAGE>
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  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
    
 
                                       13
 
<PAGE>
<PAGE>
   
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 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
    
 
                                       14
 
<PAGE>
<PAGE>
   
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  will obtain a $2,000,000
key man life insurance policy on the life of Mr. Tramontana, for the benefit  of
the  Company, effective on the date of this Prospectus. 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 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  The  Company  has
applied  to have the Common Stock approved  for quotation on the Nasdaq SmallCap
MarketSM and  believes  it  will  meet the  initial  listing  requirements  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 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
    
 
                                       16
 
<PAGE>
<PAGE>
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  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 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.'

public  offering  price of  $8.00 per  share),  after deduction  of underwriting
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
and Results of Operations' included  elsewhere in this Prospectus. The  selected
financial data 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

                    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  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'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

     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

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  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.

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 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 $538,148 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  50%  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 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 $60,996 for  the three  months
ended  March 31, 1996 represents a decline of $49,775 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 $515,955, Prostate Materials by
$443,461, and oncological products by  $391,329 which the Company began  selling
in  June 1993, November 1994, and August 1994, respectively. For the years ended
December 31, 1995 and 1994, sales of Prostate Materials
    
 
                                       29

<PAGE>
   
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 $227,471, employee benefits and other personnel costs of
$170,631, shipping costs of $92,084 and other administrative costs of  $265,806.
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

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.
    
 
   
YEAR ENDED DECEMBER 31, 1994 COMPARED TO YEAR ENDED DECEMBER 31, 1993
BIGMAR PHARMACEUTICALS
    
 
   
     Net Sales. Net sales increased by  $443,550 to $707,627 for the year  ended
December  31, 1994 as compared to $264,077 for the year ended December 31, 1993.
The increase  was due  to sales  of $205,000  of calcium  leucovorin in  Germany
beginning  in August 1994, increased sales  of $442,000 of Prostate Materials, a
reduction of $224,000 in other medical product sales and $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,  $409,000 in IV Solution  products and $451,000 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, 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 $1,007,555  and $1,325,603, respectively.  The Company's  working
capital  approximated ($437,811) and  $1,052,513 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  was $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  $11,364,805 in
outstanding  indebtedness,   including   $1,847,184  which   is   payable   upon
consummation of the Offering.
 
   
     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 $179,431  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  and Sigal  were $1,679,261  and $1,847,187,
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 $1,847,187 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 is payable with
interest at 5% through December 31, 1998 and at an adjustable rate not to exceed
6.5% through 2005. This loan commitment  has a ceiling of $1,847,187 from  which
the Company may draw, and is collateralized by the building and machinery at the
Bigmar  Facility. Principal  is payable  as follows:  3 semi-annual  payments of
$83,963 commencing December 31, 1997 and eleven semi-annual payments of $146,935
commencing June 30, 1999.
    
 
   
     The Company has  other outstanding bank  loans aggregating $1,973,728  used
for  the construction of the Bigmar Facility. These loans accrue interest at the
rate of 5% per annum through December 31, 1998 and at an adjustable rate not  to
exceed  6.5% per annum through  2005 and are collateralized  by the building and
machinery at the  Bigmar Facility  and require quarterly  principal payments  of
$31,247  commencing December 31, 1997. The bank loan has a ceiling of $2,749,790
from which the company may draw.
    
 
   
     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, and
at a variable rate thereafter tied  to the then existing competitive  commercial
mortgage  rate. The  mortgage requires  principal payments  of $50,378  per year
through 2045.
    
 
   
     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
therefor 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 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 $6.5 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

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 (i) distribute new products in the
Boehringer Territory  and  (ii)  expand  the  Boehringer  Territory  to  include
Belgium,  the Netherlands, Luxembourg, Greece and Turkey. 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
 
                                       40

Products. Unless  terminated by  either  party upon  the occurrence  of  certain
specified  conditions, the 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
    
 
                                       41
 
<PAGE>
<PAGE>
an adequate  supply  of  required  raw materials  and  components  in  order  to
manufacture  or market a 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
    
 
                                       42
 
<PAGE>
<PAGE>
   
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 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
 
                                       44
 
<PAGE>
<PAGE>
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 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 until December 31, 1998 is payable at a
rate of 5% per annum and thereafter interest is payable at a variable rate up to
6.5%.  The  first  loan is  pursuant  to a  bank  commitment with  a  ceiling of
$1,847,187 from  which the  Company  may draw,  and requires  three  semi-annual
principal payments of $83,963 commencing December 31, 1997 and eleven semiannual
payments of $146,935 commencing June 30,
    
 
                                       49
 
<PAGE>
<PAGE>
   
1999.   The  second  loan  requires  quarterly  principal  payments  of  $31,247
commencing December 31,  1997 and  has a ceiling  of $2,749,790  from which  the
Company  may  draw.  See  'Management's  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 50 year mortgage in the
approximate  principal  amount  of  $2,500,000  which  provides  for  an  annual
principal  payment of approximately  $50,000 for the  remainder of the mortgage.
Interest until May 16, 1999 is 5% per annum and thereafter the interest rate  is
subject  to adjustment based upon current  commercial mortgage rates. 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 Sigal 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.

</TABLE>
    
 
     Each  of  the  Medical Advisors  and  Scientific Advisors  will  enter into
medical  or  scientific  advisory   agreements  ('Advisory  Agreements')   which
generally  require the Medical Advisor or  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. The
Medical  Advisors and Scientific Advisors will agree to meet individually and in
groups to  advise  the Company  on  its research,  development,  operations  and
commercialization of its technology, to consult on the Company's projects and to
attend  meetings of the Medical Advisors  or 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 Medical Advisor and Scientific Advisor
will contain confidentiality provisions.
 
   
     The  Medical Advisors and 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  Medical Advisor  or 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  Medical Advisor  or
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, which 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  Medical  Advisor or  Scientific  Advisor,  against any
liabilities arising from their good faith services thereunder.
    
 
     The Company's Medical  Advisors or  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.
 
                                       54
 
<PAGE>
<PAGE>
     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.
 
   
     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.
    
 
                                       55
 
<PAGE>
<PAGE>
   
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 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
intends to obtain $2,000,000 of key-person life insurance for the benefit of the
Company on the life of Mr. Tramontana effective on the date of this Prospectus.
    
 
     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
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 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,
 
                                       56
 
<PAGE>
<PAGE>
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.

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  $2,802,504  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
$16,007,496.
    
 
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.'

TRANSACTIONS WITH DIRECTORS AND EXECUTIVE OFFICERS
 
     In  May  1995, John  G. Tramontana,  the Company's  Chairman of  the Board,
President and Chief Executive Officer, purchased 690 shares of the capital stock
of Bigmar Pharmaceuticals for $575,000.
 
     In June 1995,  John G.  Tramontana, the  Company's Chairman  of the  Board,
President and Chief Executive Officer, purchased 500 shares of the capital stock
of  Bioren  for  an  aggregate  purchase price  of  $500,000.  See  '  -- Bioren
Acquisition.'
 
     In September 1995, John G. Tramontana, the Company's Chairman of the Board,
President and Chief Executive  Officer, purchased 9,889  shares of Common  Stock
from the Company for $2,082.
 
   
     In  March 1996 the Company entered into a sublease agreement with 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
'Business -- Facilities.'
    
 
     In April  1996,  John  G.  Tramontana  entered  into  five-year  employment
agreement with the Company. See 'Management.'
 
     Upon  consummation of  the Offering,  Gerald T.  Sweeney will  enter into a
two-year employment agreement with the Company. See 'Management.'
 
   
     Eric  M.  Chen,  a  director  designee,  is  a  managing  director  of  the
Representative.  The Representative  and the  Company have  entered into certain
arrangements with respect to the Offering. See 'Management' and 'Underwriting.'
    
 
     Mr. Tramontana and Chemholding may be deemed to be founders or promoters of
the Company as that term is defined under the Securities Act.
 
   
     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

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. The Company has applied  to have the Common Stock quoted on  the
Nasdaq  SmallCap  MarketSM under  the trading  symbol 'BGMR'  and listed  on the
Boston Stock Exchange and  the Pacific Stock Exchange  under the trading  symbol
'        .'
    
 
     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 120% 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,  director  or   stockholder  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

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.

                         BIGMAR, INC. AND SUBSIDIARIES
                   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  2.105262 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 significant
intercompany accounts and transactions have been eliminated in the  consolidated
financial statements.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
    
 
   
     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.

(NOTE 9) -- LEGAL RESERVE:
    
 
     The Swiss  Federal  Code of  Obligation  provides that  at  least 5%  of  a
company's  net income each  year must be  appropriated to a  legal reserve until
such time  as  this  reserve equals  20%  of  the company's  share  capital.  In
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:

(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.

     Sales to significant customers were as follows:

Board of Directors and Stockholders
BIOREN SA
 
     We have audited the accompanying statements 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 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
period ended December 31, 1994, in conformity with generally accepted accounting
principles.

                         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
 
             (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
    
 
                                      II-4
 
<PAGE>
<PAGE>
     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.

                             UNDERWRITING AGREEMENT


                                                                   June __, 1996


LT Lawrence & Co., Inc.
350 Park Avenue
New York, New York  10022
        as the Representative of the several
        Underwriters named in Schedule I
        attached hereto.

Ladies and Gentlemen:

         The undersigned,  Bigmar, Inc., a Delaware corporation (the "Company"),
and each of the Subsidiaries (as defined in Section 2(e) below),  hereby confirm
their  agreement with you (the  "Representative"),  and the other  underwriters
named in Schedule I hereto (the Representative and the other underwriters being
herein collectively referred to as the "Underwriters"), as follows:

         1. General.  Subject to the terms and  conditions  stated  herein,  the
Company  proposes to issue and sell to the  Underwriters  1,250,000  shares (the
"Firm Shares") of common stock,  par value $.001 per share,  of the Company (the
"Common   Stock")   and  to  sell  to  the   Representative   a  warrant   (the
"Representative's  Warrant")  which  entitles  the holders to  purchase  125,000
shares of Common  Stock until June __, 2001 at an exercise  price of 120% of the

         2.  Representations and Warranties of the Company and the Subsidiaries.
The Company and each Subsidiary, jointly and severally,  represents and warrants
to, and agrees with, the several Underwriters that:

         (a) The Company has filed with the Securities  and Exchange  Commission
(the  "Commission")  a  registration  statement,  and may have filed one or more
amendments thereto,  on Form S-1 (Registration No. 333-3830),  including in such
registration   statement  and  each  such  amendment  and  related   preliminary
prospectus, for the registration of the Shares under the Securities Act of 1933,
as  amended  (the  "Act").  As used in this  Agreement,  the term  "Registration
Statement"  means such  registration  statement,  as  amended,  on file with the
Commission at the time such  registration  statement becomes effective under the
Act (including the prospectus,  financial  statements,  exhibits,  and all other
documents filed as a part thereof),  provided,  however,  that such registration
statement,  at the  time it  becomes  effective  under  the Act,  may omit  such
information as is permitted to be omitted from such registration  statement when
it becomes  effective  under the Act pursuant to Rule 430A of the General  Rules
and Regulations of the Commission promulgated under the Act (the "Regulations"),
which information (the "Rule 430A  Information")  shall be deemed to be included
in such  registration  statement  when a final  prospectus  is  filed  with  the
Commission  in  accordance   with  Rules  430A  and  424(b)(1)  or  (4)  of  the
Regulations; the term "Preliminary Prospectus" means each prospectus included in
the Registration  Statement,  or any amendments thereto, before the Registration
Statement becomes  effective under the Act, the form of prospectus  omitting the
Rule  430A  Information   included  in  the  Registration   Statement  when  the
Registration Statement becomes effective under the Act, if applicable (the "Rule
430A  Prospectus"),  and any  prospectus  filed by the Company with your consent
pursuant to Rule 424(a) of the Regulations;  and the term "Prospectus" means the
final  prospectus  included as part of the  Registration  Statement  in the form
first  filed  with  the  Commission  pursuant  to Rule  424(b)(1)  or (4) of the
Regulations or, if no such filing is required,  the final form of the prospectus
forming a part of the Registration Statement.

         (b) When the Registration  Statement  becomes or became effective under
the Act, and at all times subsequent  thereto, to and including the Closing Date
(as  defined in  Section  3) and each  Additional  Closing  Date (as  defined in
Section 3), and during such longer period as the  Prospectus  may be required to
be delivered  in  connection  with sales by the  Underwriters  or a dealer,  and
during such longer  period  until any  post-effective  amendment  thereto  shall
become   effective   under  the  Act,  the   Registration   Statement  (and  any
post-effective   amendment  thereto)  and  the  Prospectus  (as  amended  or  as
supplemented  if the Company shall have filed with the  Commission any amendment
or supplement to the Registration  Statement or the Prospectus) will contain all
statements  which are required to be stated  therein in accordance  with the Act
and the  Regulations,  will  comply  with  the Act  and the  Regulations  in all
material respects,  and will not contain any untrue statement of a material fact
or omit to state any material fact required to be stated therein or necessary to
make the statements  therein not misleading  (or, in the case of the Prospectus,
will not include any untrue  statement  of a material  fact or omit to state any
material fact necessary in order to make the statements therein, in light of the
circumstances  under which they were made,  not  misleading),  and no event will
have




                                       2

occurred  which should have been set forth in an amendment or  supplement to the
Registration  Statement or the  Prospectus  which has not then been set forth in
such amendment or supplement;  if a Rule 430A  Prospectus is contemplated at the
time the Registration  Statement becomes effective under the Act, the Prospectus
filed  pursuant  to Rules  430A and  424(b)(1)  or (4) of the  Regulations  will
contain all Rule 430A  Information  and all statements  which are required to be
stated therein in accordance with the Act and the Regulations,  will comply with
the Act and the Regulations in all material  respects,  and will not contain any
untrue statement of a material fact or omit to state any material fact necessary
in order to make the statements  therein,  in light of the  circumstances  under
which they were made, not misleading; and each Preliminary Prospectus, as of the
date filed with the Commission,  contained all statements  required to be stated
therein in accordance  with the Act and the  Regulations,  complied with the Act
and the  Regulations  in all material  respects,  and did not include any untrue
statement  of a material  fact or omit to state any material  fact  necessary in
order to make the statements  therein, in light of the circumstances under which
they were made, not misleading.  No  representation  or warranty is made in this
Section 2(b), however, with respect to statements in the Registration  Statement
or the  Prospectus,  or any  related  Preliminary  Prospectus  or any  amendment
thereof or supplement  thereto,  made in reliance upon, and in conformity  with,
written  information  furnished  to the  Company as stated in Section  8(b) with
respect  to  any  Underwriter   expressly  for  inclusion  in  the  Registration
Statement,  the  Prospectus,  or  any  related  Preliminary  Prospectus,  or any
amendment or supplement thereto.

         (c) Neither the Commission  nor the "blue sky" or securities  authority
of any  jurisdiction  has  issued  an  order  (a "Stop  Order")  suspending  the
effectiveness of the Registration Statement, or preventing or suspending the use
of any Preliminary  Prospectus,  the Prospectus,  the Registration Statement, or
any amendment or supplement  thereto, or refusing to permit the effectiveness of
the Registration  Statement,  or suspending the registration or qualification of
the  Shares,  nor have  any of such  authorities  instituted  or  threatened  to
institute any proceedings with respect to a Stop Order.

         (d) Any contract, agreement,  instrument, lease, license, certification
or permit or other arrangement,  whether written or oral, required by the Act or
the Regulations to be described in the Registration  Statement or the Prospectus
has been  properly  described  as required  therein.  Any  contract,  agreement,
instrument, lease, license, certification,  permit or other arrangement required
to be filed as an exhibit to the Registration  Statement has been filed with the
Commission as an exhibit to the  Registration  Statement.  The statements in the
Registration  Statement or the  Prospectus  summarizing  the provisions of laws,
rules, regulations, contracts, leases and other arrangements, whether written or
oral, including, without limitation, the statements set forth under the captions

arrangements  purported to be summarized and there are no proposed amendments or
additions to any such provisions of laws, rules, regulations,  contracts, leases
or other arrangements.

         (e) The Company's only subsidiaries (as defined in the Regulations) are
(i)  Bigmar   Therapeutics,   Inc.  ("Bigmar   Therapeutics"  or  the  "Delaware
Subsidiary"),  a Delaware corporation,  (ii) Bigmar  Pharmaceuticals SA ("Bigmar
Pharmaceuticals"), a Swiss corporation, and (iii) Bioren SA, a Swiss corporation
("Bioren,"  and together with Bigmar  Therapeutics  and Bigmar  Pharmaceuticals,
collectively,  the "Subsidiaries" or individually, a "Subsidiary").  The Company
owns  directly  or  through  a  wholly  owned  subsidiary  (as  defined  in  the
Regulations)  100%  of  the  issued  and  outstanding   capital  stock  of  each
Subsidiary.  The Company and each  Subsidiary is a corporation  duly  organized,
validly  existing and in good standing under the laws of the state or country of
its incorporation,  with full power and authority,  and all necessary  consents,
authorizations,  approvals, orders, licenses,  certificates,  and permits of and
from,  and  declarations  and filings with all Federal,  state,  local and other
governmental  authorities and all courts and other tribunals having jurisdiction
over such entities  (collectively,  the "Consents,  Licenses and  Approvals") to
own,  lease,  license  and use its  properties  and assets  and to  conduct  its
businesses in the manner  described in the Prospectus,  except where the failure
to obtain  such  Consents,  Licenses  and  Approvals  would not have a  material
adverse  effect  on  the  Company  or  any  Subsidiary,  individually  or in the
aggregate (a "Material Adverse Effect"). The Company and each Subsidiary is duly
qualified to do business and is in good standing in every  jurisdiction in which
its ownership,  leasing,  licensing or use of property and assets or the conduct
of its businesses makes such qualification  necessary,  except where the failure
to be so qualified would not have a Material Adverse Effect.  Each of the Bioren
Acquisition, the Contribution,  the Exchange and the Reverse Split has been duly
authorized by all necessary  proceedings and has been  consummated in accordance
with applicable law.

         (f) The authorized  capital stock of the Company consists of 15,000,000
shares of Common Stock, of which  3,625,000  shares are  outstanding,  5,000,000
shares of  Preferred  Stock,  $0.001  par  value,  of which  there are no shares
outstanding.  Each  outstanding  share of capital  stock of the Company and each
Subsidiary  is validly  authorized  and issued,  fully paid and  non-assessable,
without any personal liability  attaching to the ownership thereof,  and has not
been issued and is not owned or held in  violation  of any  preemptive  or other
similar rights of stockholders.  There is no commitment,  plan or arrangement to
issue,  and no  outstanding  option,  warrant  or other  right  calling  for the
issuance of, any share of capital stock of the Company or any  Subsidiary or any
security or other instrument which by its terms is convertible into, exercisable
for, or exchangeable for capital stock of the Company or any Subsidiary,  except
as described in the Prospectus.  Except as set forth in the Prospectus, there is
outstanding  no



                                       4

security  or  other  instrument  which  by its  terms is  convertible  into,  or
     exchangeable for, capital stock of the Company or any Subsidiary. The
certificates evidencing the Common Stock are in due and proper form.

         (g) The  financial  statements  of the Company and Bigmar  Therapeutics
(including  the notes  thereto  and the  supporting  schedules)  included in the
Registration  Statement and the Prospectus (the "Company Financial  Statements")
comply in all  material  respects  with the  requirements  of the Act and fairly
present the consolidated financial position, results of operations,  cash flows,
and the other information  purported to be shown therein at the respective dates
and for the  respective  periods  to  which  they  apply  with  respect  to such
entities. The Company Financial Statements have been prepared in accordance with
generally accepted  accounting  principles  consistently  applied throughout the
periods  involved,  are correct and complete in all material respects and are in
accordance  with the books and records of the Company.  The  combined  financial
statements of Bigmar  Pharmaceuticals and Bioren and the financial statements of
Bioren (in each case including the notes thereto and the  supporting  schedules)
included in the Registration  Statement and the Prospectus)  (collectively,  the
"Subsidiary  Financial  Statements")  comply in all material  respects  with the
requirements  of the Act and fairly present the financial  position,  results of
operations,  cash flows, and the other information purported to be shown therein
at the respective dates and for the respective  periods to which they apply with
respect to such entities. The Subsidiary Financial Statements have been prepared
in accordance with generally accepted accounting principles consistently applied
throughout  the  periods  involved,  are correct  and  complete in all  material
respects and are in accordance with the books and records of such  Subsidiaries.
Richard A. Eisner & Company,  LLP, the  accountants  whose report on the audited
financial  statements is filed with the Commission as a part of the Registration
Statement, is, and during the periods covered by their report(s) included in the
Registration  Statement and the Prospectus  were,  independent  certified public
accountants  with respect to the Company and each Subsidiary  within the meaning
of the Act and the  Regulations.  No other financial  statements are required by
Form S-1 or  otherwise  to be  included  in the  Registration  Statement  or the
Prospectus.   The  assumptions   used  in  preparing  the  pro  forma  financial
information  included in the Prospectus under the captions  "Summary  Historical
and Pro  Forma  Financial  Data,"  "Capitalization,"  "Dilution"  and  "Selected
Financial Data" are reasonable.  The historical financial  information appearing
in the Prospectus under the captions "Summary Historical and Pro Forma Financial
Data" and "Selected Financial Data" presents fairly the information purported to
be shown therein,  on the basis stated in the Prospectus as of the dates and for
the periods indicated.

         (h) There is no litigation,  arbitration,  claim, governmental or other
proceeding (formal or informal) or investigation pending or, to the knowledge of
the Company and its  Subsidiaries  after due inquiry,  threatened,  or any basis
therefor known to the Company and its Subsidiaries,  with respect to the Company
or any Subsidiary or any of their respective operations,  businesses, properties
or assets. The Company and each Subsidiary is not in violation of, or in default
with respect to, any law, rule,  regulation,  order,  judgment or decree,  which
would now have, or will in the future have, a Material  Adverse  Effect,  nor is
the



                                       5

Company or any Subsidiary required to take any action in order to avoid any such
 violation or default of any order, judgment or decree.

         (i) The Company and each  Subsidiary has (1) good and marketable  title
in fee  simple  absolute  to all real  properties,  and good  title to all other
properties and assets,  which the Prospectus indicates are owned by it, free and
clear of all liens, claims, security interests,  pledges, charges,  encumbrances
and mortgages,  except as described in the Prospectus, and (2) valid, subsisting
and enforceable leases for the property described in the Prospectus as leased by
it (except as described in the  Prospectus).  No real  property  owned,  leased,
licensed or used by the Company or any  Subsidiary  lies in an area which is, or
to the knowledge of the Company and its Subsidiaries after due inquiry, will be,
subject to zoning,  use or building code  restrictions  which would prohibit its
ownership,  leasing,  licensing  or use or which  would  prevent  the  continued
effective  ownership,  leasing,  licensing  or use of such real  property in the
business of the  Company or any  Subsidiary  as  presently  conducted  or as the
Prospectus indicates the Company or any Subsidiary will conduct in the future.

         (j) Neither the Company nor any Subsidiary nor, to the knowledge of the
Company and its  Subsidiaries  after due inquiry,  any other party, is now or is
expected to be in  violation  or breach of, or in default  with  respect to, any
material  provision of any  contract,  agreement,  instrument,  lease,  license,
arrangement or  understanding  to which the Company or any Subsidiary is a party
or by which its  properties  or assets  may be  bound,  and each such  contract,
agreement,  instrument, lease, license, arrangement and understanding is in full
force and effect and is the legal,  valid and binding  obligation of the Company
or the  Subsidiary,  as the case may be, and is enforceable as to the Company or
the Subsidiary, as the case may be, in accordance with its terms, except as such
enforceability  may be limited by  bankruptcy,  insolvency or other similar laws
affecting  the  enforceability  of  creditors'  rights  generally,  by equitable
principles  and  applicable  laws  governing  indemnification  and  contribution
provisions.  The Company and each  Subsidiary  enjoys  peaceful and  undisturbed
possession  under all leases and licenses  under which it is operating.  Neither
the  Company  nor any  Subsidiary  is a party  to, or bound  by,  any  contract,
agreement,  instrument,  lease, license,  arrangement or understanding,  whether
written or oral, or subject to any charter or other restriction,  which has had,
or is expected to have, a Material  Adverse Effect.  Neither the Company nor any
Subsidiary is in violation or breach of, or in default with respect to, any term
of its certificate of incorporation (or other charter document) or by-laws.

         (k) All patents, patent applications,  licenses, trademarks,  trademark
applications, trade names, service marks, copyrights,  franchises, licenses, and
other intangible properties and assets (all of the foregoing being herein called
"Intangibles")  that the Company or any Subsidiary owns or has pending, or under
which it is licensed, are in good standing and, to the knowledge of the Company,
uncontested. There is no right under any Intangible necessary to the business of
the  Company or any  Subsidiary  as  presently  conducted  or as the  Prospectus
indicates they  contemplate  conducting,  except as described in the Prospectus.
Neither the Company nor any  Subsidiary has  infringed,  is  infringing,  or has
received  notice of  infringement  or conflict  with respect to  Intangibles  of
others.  Neither the Company nor any



                                       6
<PAGE>
<PAGE>



Subsidiary  knows of any  infringement  by others of Intangibles of  the Company
or any Subsidiary.

         (l)  The  Company  and  each  Subsidiary  is  insured  by  insurers  of
recognized  financial  responsibility  against such losses and risks and in such
amounts as are prudent, customary and adequate for the businesses in which it is
engaged,  including,  but  not  limited  to,  general  liability  insurance  and
insurance  covering real and personal property owned or leased by the Company or
any Subsidiary  against theft,  damage,  destruction,  acts of vandalism and all
other risks customarily insured against by any company that is comparable to the
Company or any Subsidiary in terms of its respective financial condition, all of
which  insurance  is in full  force and  effect.  Neither  the  Company  nor any
Subsidiary  has reason to believe that it will not be able to renew its existing
insurance  coverage  as and when such  coverage  expires  or to  obtain  similar
coverage  from similar  insurers as may be necessary to continue its  respective
businesses at a cost that would not now have a Material Adverse Effect.

         (m) Neither the Company nor any Subsidiary  nor any director,  officer,
agent,  employee or other person  associated  with,  or acting on behalf of, the
Company or any Subsidiary  has,  directly or  indirectly,  at any time since the
inception of the Company or any Subsidiary: used the funds of the Company or any
Subsidiary for unlawful contributions,  gifts, entertainment,  or other unlawful
expenses relating to political activity; made any unlawful payment to foreign or
domestic  government  officials or employees or to foreign or domestic political
parties or campaigns from funds of the Company or any  Subsidiary;  violated any
provision of the Foreign Corrupt Practices Act of 1977 (the "FCPA"), as amended;
or made any unlawful payment. The internal accounting controls and procedures of
the Company is  sufficient  to cause the Company to comply in all respects  with
the  Securities  Exchange Act of 1934, as amended (the  "Exchange  Act") and the
FCPA.

         (n) The  Company  and  each  Subsidiary  has all  requisite  power  and
authority   to   execute,   deliver   and  perform   this   Agreement   and  the
Representative's Warrant, as the case may be, and to consummate the transactions
contemplated  hereby and thereby,  including,  but not limited to, the power and
authority to issue, sell and deliver the Shares and the Representative's Warrant
being  delivered by the Company in accordance  with and upon the terms set forth
in this  Agreement and the  Representative's  Warrant.  All necessary  corporate
proceedings of the Company and each  Subsidiary has been duly taken to authorize
the   execution,   delivery,   and   performance   of  this  Agreement  and  the
Representative's Warrant by the Company and each Subsidiary, as the case may be,
and to  consummate  the  transactions  contemplated  hereby  and  thereby.  This
Agreement  has been duly  authorized,  executed and delivered by the Company and
each Subsidiary,  is the legal,  valid and binding obligation of the Company and
each  Subsidiary and is enforceable  against the Company and each  Subsidiary in
accordance  with its  terms,  except as such  enforceability  may be  limited by
bankruptcy,  insolvency or other similar laws  affecting the  enforceability  of
creditors'  rights  generally,  by  equitable  principles  and  applicable  laws
governing  indemnification  and contribution  provisions.  The  Representative's
Warrant has been duly authorized by the Company, and when executed and delivered
by the Company,  will be the legal,  valid and binding obligation of the Company
and enforceable against



                                       7

the Company in accordance with its terms,  except as such  enforceability may be
limited by bankruptcy, insolvency or other similar laws affecting or relating to
creditors'   rights   generally  and  by  equitable   principles.   No  consent,
authorization, approval, order, registration, license, certificate, or permit of
or from,  or  declaration  or filing with,  any Federal,  state,  local or other
governmental  or  regulatory  authority  or any court or other  tribunal  having
jurisdiction  over such  entities is  required  for the  execution,  delivery or
performance  by the  Company  and  each  Subsidiary  of  this  Agreement  or the
Representative's  Warrant,  as the  case  may  be,  or the  consummation  of the
transactions  contemplated hereby and thereby (including the issuance,  sale and
delivery  of the Shares  and  Representative's  Warrant  to be issued,  sold and
delivered by the Company),  except filings under the Act which have been or will
be made  before the  Closing  Date (as  defined in Section 3) and such  consents
consisting  only of consents under "blue sky" or securities laws which have been
obtained at or prior to the date of this  Agreement.  No consent of any party to
any  contract,   agreement,   instrument,   lease,   license,   arrangement   or
understanding to which the Company or any Subsidiary is a party, or to which the
Company's  or any of the  Subsidiaries'  properties  or  assets is  subject,  is
required for the  execution,  delivery or  performance  of this Agreement or the
Representative's  Warrant or the consummation of the  transactions  contemplated
hereby or thereby. The execution, delivery and performance of this Agreement and
the   Representative's   Warrant  and  the   consummation  of  the  transactions
contemplated hereby or thereby will not: (1) violate,  result in a breach of any
of the terms and  provisions  of,  conflict  with,  result  in the  creation  or
imposition of any lien,  charge or encumbrance  upon any properties or assets of
the Company or any Subsidiary  pursuant to the terms of, or, with or without the
giving of notice or the passage of time or both,  entitle any party to terminate
or call a default under, any contract,  agreement,  instrument,  lease, license,
arrangement,  or understanding to which the Company or any Subsidiary is a party
or by which its  respective  properties or assets may be bound;  or (2) violate,
result  in a  breach  of,  or  conflict  with,  any term of the  certificate  of
incorporation  (or other  charter  document)  or by-laws  of the  Company or any
Subsidiary;  or (3) violate,  result in a breach of, or conflict  with, any law,
rule,  regulation,  order,  judgment  or  decree  of any  court  or any  public,
governmental or regulatory authority having jurisdiction over the Company or any
Subsidiary  or any of their  respective  operations,  businesses,  properties or
assets.

         (o) The Shares are validly  authorized and, when issued,  delivered and
sold in accordance with this Agreement,  will be validly issued and outstanding,
fully paid and  non-assessable,  without any personal liability attaching to the
ownership  thereof and will not have been issued in  violation  of or subject to
any preemptive or similar rights of stockholders to subscribe for or to purchase
such Shares.  The  Underwriters  will receive good and valid title to the Shares
purchased  from the  Company,  free and  clear of all  liens,  claims,  security
interests, pledges, charges,  encumbrances,  stockholders' agreements and voting
trusts and other  defects in title.  The Shares and the Common Stock  conform to
all statements  relating thereto contained in the Registration  Statement or the
Prospectus.

         (p) The  Representative's  Warrant and the  Warrant  Shares are validly
authorized (and, in the case of the Warrant Shares, reserved for issuance), and,
when  the  Warrant  Shares  are  issued  and  delivered  upon  exercise  of  the
Representative's  Warrant in



                                       8

accordance with the terms thereof will be validly issued and outstanding,  fully
paid  and  non-assessable,  without  any  personal  liability  attaching  to the
ownership  thereof and will not have been issued in  violation  of or subject to
any preemptive or similar rights of stockholders to subscribe for or to purchase
the  Representative's  Warrant  or  the  Warrant  Shares.  The  holders  of  the
Representative's Warrant will receive good and valid title to the Warrant Shares
purchased by them,  respectively,  free and clear of all liens, claims, security
interests, pledges, charges,  encumbrances,  stockholders' agreements and voting
trusts and other defects in title. The Representative's  Warrant and the Warrant
Shares conform to all statements  relating thereto contained in the Registration
Statement or the Prospectus.

         (q) Subsequent to the respective dates as of which information is given
in the Registration Statement and the Prospectus, and except as may otherwise be
properly  described in the  Prospectus,  neither the Company nor any  Subsidiary
has: (i) issued any securities or incurred any liability or obligation,  primary

ordinary  course of  business,  (iii)  declared  or paid any  dividend  on their
respective   capital  stock,   (iv)  experienced  any  adverse  changes  or  any
development  which is  expected to  materially  adversely  affect the  condition

business, key personnel,  assets or properties of the Company or any Subsidiary,
individually  or in the aggregate or (v) made any change in its capital stock or
made any issuance of options,  warrants,  convertible securities or other rights
to purchase the capital stock of the Company or any Subsidiary.

         (r)  Neither  the Company or any  Subsidiary  nor any of the  officers,
directors or affiliates  (as defined in the  Regulations)  of the Company or any
Subsidiary,  has taken or will take, directly or indirectly, any action designed
to stabilize or  manipulate  the price of any security of the Company,  or which
has caused or resulted in, or which might  reasonably  be expected in the future
to cause  or  result  in,  stabilization  or  manipulation  of the  price of any
security of the Company or to facilitate the sale or resale of any the Shares.

         (s) The  Company has  obtained  from each of its  directors,  executive
officers (as defined in the  Regulations),  all persons  deemed to be affiliates
(as defined in the  Regulations)  of the  Company and from any other  person who
beneficially  owns shares of Common Stock (or any  security or other  instrument
which by its terms is convertible  into,  exercisable for, or exchangeable  for,
shares of Common Stock)  (collectively,  the "Insiders") an enforceable  written
agreement,   in  form   and   substance   satisfactory   to   counsel   for  the
Representative,  which provides that for a period of one (1) year from the date
of the  Prospectus  each Insider will not,  without your prior written  consent,
directly or indirectly,  register, offer, sell, offer to sell, contract to sell,
grant an  option  for the sale of,  assign,  hypothecate,  pledge  or  otherwise
dispose of any  securities of the Company,  other than the transfer of shares of
the Company's Common Stock by the Insiders to (i) any spouse, parent, sibling or
lineal  descendants  of the  Insiders,  (ii) any trust for the  benefit  of such
Insiders, (iii) any distributee, legatee or devisee of the Insiders who acquires
its  shares by will or  operation  of law upon the death or  dissolution  of the
Insiders,  or (iv) any current holder of capital stock of the Company,  provided
that in each case such transferee  agrees in writing to be bound by the terms of
this   subsection   to  the  same  extent  as  if


                                       9

they were parties hereto.  Notwithstanding  the foregoing,  the   Representative
acknowledges that at the Closing Date no more than 12% of the  Company's  issued
and  outstanding  Common Stock held by certain  Insiders may be pledged to third
parties.

         (t) Neither the  Company nor any  Subsidiary  is, or intends to conduct
its business in a manner in which it would become,  an  "investment  company" as
defined in Section 3(a) of the  Investment  Company Act of 1940, as amended (the
"Investment Company Act").

         (u) No person or entity has the right to require registration of shares
of Common Stock or other securities of the Company or any Subsidiary.

         (v) Neither the Company nor any  Subsidiary  has incurred any liability
for a fee,  commission or other  compensation  on account of the employment of a
broker  or finder  in  connection  with the  transactions  contemplated  by this

         (w) The Company and each  Subsidiary is (1) in compliance  with any and
all applicable Federal, state and local environmental laws, rules,  regulations,

relating to the protection of human health and safety,  the environment or toxic
substances or wastes, pollutants or contaminants (the "Environmental Laws"), (2)
has received all permits,  licenses or other approvals required under applicable
Environmental Laws to conduct its businesses,  and (3) is in compliance with all
terms and conditions of any such permit, license or approval,  except where such
noncompliance  with  Environmental  Laws,  failure to receive required  permits,
licenses or other  approvals or failure to comply with the terms and  conditions
of such  permits,  licenses  or  approvals  would  not,  individually  or in the
aggregate,  have a Material Adverse Effect.  No action,  proceeding,  revocation
proceeding,  writ,  injunction  or claim is pending or  threatened  (nor, to the
knowledge  of the Company  and its  Subsidiaries,  is there any basis  therefor)
relating to the  Environmental  Laws or to the  activities of the Company or any
Subsidiary  involving  Hazardous  Materials.  "Hazardous  Materials"  means  any
material or substance (i) that is  prohibited or regulated by any  environmental
law,  rule,  regulation,  order,  treaty,  statute  or code  promulgated  by any
governmental  authority,  or any amendment or modification thereto, or (ii) that
has been designated or regulated by any  governmental  authority as radioactive,
toxic,  hazardous  or  otherwise  a  danger  to  health,   reproduction  or  the
environment.  There  have  been no  costs  or  liabilities  associated  with the
compliance with Environmental Laws that would, individually or in the aggregate,
have a Material Adverse Effect.

         (x)  No  officer,  director  or  stockholder  of  the  Company  or  any
Subsidiary has any affiliation or association  with the National  Association of
Securities Dealers, Inc. (the "NASD") or any member thereof.

Subsidiary has filed all necessary  Federal,  state,  local and foreign  income,
franchise and other tax returns and other  reports  required to be filed and has
paid all taxes shown as due thereon; and there is




                                       10
<PAGE>
<PAGE>


no tax  deficiency  which has been, or, to the best knowledge of the Company and
its  Subsidiaries  after due inquiry,  might be, asserted against the Company or
any Subsidiary.

         (z)  None  of  the  activities  or  businesses  of the  Company  or any
Subsidiary  is in  violation  of, or is  expected  to cause the  Company  or any
Subsidiary to violate, any law, rule, regulation or order of any foreign country
or foreign  governmental  agency or body or the United States, any state, county
or  locality,  or of any  agency or body of the  United  States or of any state,
county or locality, the violation of which would have a Material Adverse Effect.

         (aa)  Neither  Company  nor  any  Subsidiary  has  distributed  or will
distribute  any  prospectus or other  offering  material in connection  with the
offering and sale of the Shares,  other than any  Preliminary  Prospectus or the
Prospectus or other materials permitted by the Act and the Regulations to be

distributed.

         (ab) Neither the U.S. Food and Drug  Administration  nor any comparable
regulatory  agency  outside the United  States has  commenced or  threatened  to
initiate  any action to withdraw  its  approval of any product of the Company or
any  Subsidiary  or, to the best  knowledge of the Company and its  Subsidiaries
after due inquiry,  commenced, or threatened to initiate, any action to withdraw
approval of any facility of the Company or any  Subsidiary.  All of the products
of the Company and each Subsidiary are in compliance with any and all applicable
laws, rules,  regulations and arrangements concerning the development,  testing,
handling,   manufacturing,   distribution  and  commercialization  of  hospital,
pharmaceutical,  biotechnological or similar products  (collectively,  the "Drug
Laws").

         (ac) Any contract, agreement, instrument, lease, license, certification
or permit or other  arrangement  described in the Registration  Statement or the
Prospectus  to which the Company or any  Subsidiary  is a party is in full force
and effect and is a legal,  valid and binding obligation between the parties and
is enforceable  against the parties in accordance with its terms, except as such
enforceability  may be limited by  bankruptcy,  insolvency or other similar laws
affecting  the  enforceability  of creditors'  rights  generally or by equitable
principles.

         5. Covenants of the Company and the Subsidiaries.  The Company and each
Subsidiary,  jointly  and  severally,  covenants  and  agrees  with the  several
Underwriters that:

         (a) If the Registration  Statement has not yet been declared  effective
under the Act, the Company  will use its best efforts to cause the  Registration
Statement  to become  effective  under the Act as promptly as  possible.  If the
Registration Statement has become or becomes effective under the Act with a form
of prospectus  omitting Rule 430A  Information,  or filing of the  Prospectus is
otherwise  required under Rule 424(b) of the Regulations,  the Company



                                       13
<PAGE>
<PAGE>





will file the  Prospectus,  properly  completed  pursuant  to Rule 424(b) of the
Regulations,  within  the  time  period  prescribed  and will  provide  evidence
satisfactory to you of such timely filing.

         (b) The Company will notify you immediately,  and promptly confirm such
notice in writing:  (i) when the Registration  Statement and any  post-effective
amendment  thereto  becomes  effective under the Act; (ii) of the receipt of any
comments from the  Commission  or the "blue sky" or securities  authority of any
jurisdiction regarding the Registration Statement,  any post-effective amendment
thereto,  the Prospectus,  or any amendment or supplement thereto;  (iii) of the
filing with the  Commission of any  supplement to the  Prospectus;  and (iv) the
receipt of any  notification  with respect to a Stop Order or the  initiation or
threatening of any proceeding with respect to a Stop Order. The Company will use
its best  efforts to prevent  the  issuance  of any Stop Order and,  if any Stop
Order is issued, to obtain the lifting thereof as promptly as possible.

         (c)  During  the time  when a  prospectus  relating  to the  Shares  is
required to be  delivered  hereunder  or under the Act or the  Regulations,  the
Company  will comply with all  requirements  imposed  upon it by the Act, as now
existing and as hereafter amended, and by the Regulations,  as from time to time
in force, so far as necessary to permit the continuance of sales of, or dealings
in, the Shares in accordance with the provisions hereof and the Prospectus.  If,
at any time when a prospectus relating to the Shares is required to be delivered
hereunder or under the Act or the Regulations,  any event shall have occurred as
a result of which,  in the  reasonable  opinion  of counsel  for the  Company or
counsel  for  the  several  Underwriters,  the  Registration  Statement  or  the
Prospectus as then amended or  supplemented  contains any untrue  statement of a
material fact or omits to state any material fact required to be stated  therein
or  necessary  to make the  statements  therein  not  misleading,  or if, in the
opinion  of  either of such  counsel,  it is  necessary  at any time to amend or
supplement the  Registration  Statement or the Prospectus to comply with the Act
or the Regulations, the Company will immediately notify you and promptly prepare
and file with the Commission an appropriate amendment or supplement (in form and
substance  satisfactory to you) which will correct such statement or omission or
which will effect such compliance and will use its best efforts to have any such
amendment declared effective under the Act as soon as possible.

         (d) The  Company  will  deliver  without  charge to each of the several
Underwriters  such  number  of  copies  of each  Preliminary  Prospectus  as may
reasonably  be requested by the  Underwriters  and, as soon as the  Registration
Statement,  or any  amendment  thereto,  becomes  effective  under  the Act or a
supplement  is filed  with the  Commission,  deliver  without  charge to you two
signed  copies  of the  Registration  Statement,  including  exhibits,  or  such
amendment thereto, as the case may be, and two copies of any supplement thereto,
and deliver  without charge to each of the several  Underwriters  such number of
copies  of the  Prospectus,  the  Registration  Statement,  and  amendments  and
supplements thereto, if any, without exhibits, as you may request.

         (e) The Company will endeavor in good faith,  in cooperation  with you,
at or prior to the time the Registration  Statement  becomes effective under the
Act,  to  qualify  the

jurisdictions as you may designate and maintain such qualification in effect for
so long as is required for the distribution of such Shares;  provided,  however,
that no such  qualification  shall be required in any  jurisdiction  where, as a
result thereof, the Company would be subject to service of general process or to
taxation as a foreign  corporation  doing business in such jurisdiction to which
it is not then subject.  In each jurisdiction where such qualification  shall be
effected,  the Company will, unless you agree in writing that such action is not
at the time necessary or advisable,  file and make such statements or reports at
such times as are or may be required by the laws of such jurisdiction.

         (f) The Company will make  generally  available  (within the meaning of

Registration  Statement occurs under the Act, an earnings  statement (which need
not be certified by independent  certified public accountants unless required by
the Act or the  Regulations,  but which shall satisfy the  provisions of Section
11(a)  of the Act and the  Regulations)  covering  a period  of at least  twelve
months beginning after the date on which the Registration Statement was declared

directly or indirectly, issue, register, offer, sell, offer to sell, contract to
sell, grant an option for the sale of, assign, hypothecate,  pledge or otherwise
dispose of any  securities of the Company or any  Subsidiary (or any security or
other  instrument  which by its terms is convertible  into,  exercisable for, or
exchangeable  for shares of  capital  stock of the  Company or any  Subsidiary),
except for (a) the grant of  options by the  Company  pursuant  to stock  option

this subsection to the same extent as if they were parties hereto.

its consolidated  subsidiaries which have been read by the Company's independent
certified public accountants, as stated in their letter to be furnished pursuant

unless such filing shall comply with the Act and the Regulations in all material
respects  and unless you shall  previously  have been advised of such filing and
furnished with a copy thereof,  and you and counsel for the  Underwriters  shall

you, to the effect that:

                (i)  Each  of the  Company  and  the  Delaware  Subsidiary  is a
corporation duly organized, validly existing and in good standing under the laws
of the State of Delaware,  with full corporate power and authority,  and, to the
best of such counsel's knowledge after diligent inquiry, all necessary Consents,
Licenses and Approvals to own, lease,  license and use its properties and assets
and to conduct its business in the manner  described in the Prospectus.  Each of
the Company and the Delaware  Subsidiary  is duly  qualified to do business as a
foreign  corporation and is in good standing in every  jurisdiction in which its
ownership, leasing, licensing or use of its properties and assets or the conduct
of its business requires such  qualification,  except where the failure to be so

after diligent inquiry, has been consummated in accordance with applicable law.

                          (ii)  The  authorized  capital  stock  of the  Company

outstanding,  and  5,000,000  of Preferred  Stock,  of which there are no shares
outstanding.  The Company's only  subsidiaries are Bigmar  Therapeutics,  Bigmar
Pharmaceuticals  and Bioren. The Company owns directly or indirectly 100% of the
issued  and  outstanding  capital  stock of each  Subsidiary.  The  certificates
evidencing  the Common Stock are in due and proper legal form and have been duly
authorized for issuance by the Company.  All of the outstanding shares of Common
Stock of the  Company  and the  Delaware  Subsidiary  have been duly and validly
authorized and issued and are fully paid and non-assessable,  and none have been
issued in violation of any preemptive or other similar  rights of  stockholders.
There is no commitment,  plan or arrangement to issue and no outstanding option,
warrant or other right  calling for the issuance of, any share of capital  stock
of the Company or the Delaware  Subsidiary  or any security or other  instrument
which by its terms is convertible  into,  exercisable  for, or exchangeable  for
capital stock of the Company or the Delaware Subsidiary,  except as described in
the Prospectus.  Except as set forth in the Prospectus,  there is outstanding no
security  or  other  instrument  which  by its  terms is  convertible  into,  or

has all requisite corporate power and authority to execute,  deliver and perform
this  Agreement  and the  Representative's  Warrant,  as the case may be, and to
consummate the  transactions set forth thereby,  including,  but not limited to,
the  power  and  authority  to  issue,  sell  and  deliver  the  Shares  and the
Representative's  Warrant (and when issued,  the Warrant Shares).  All necessary
corporate action has been duly and validly taken by the Company and the Delaware
Subsidiary to authorize the execution,  delivery and  performance by the Company
and the Delaware Subsidiary of this Agreement and the Representative's  Warrant,
as the case may be, and to consummate the transactions  set forth thereby.  This
Agreement and the  Representative's  Warrant have been duly and validly executed
and  delivered by the Company and the Delaware  Subsidiary,  as the case may be,
are the legal,  valid and binding  obligations  of the Company and the  Delaware
Subsidiary,  as the case may be, and are enforceable against the Company and the
Delaware  Subsidiary,  as the case may be, in accordance  with their  respective
terms,  except  as such  enforceability  may be  limited  by (a) the  effect  of
bankruptcy,  insolvency,  reorganization,  moratorium, fraudulent conveyance and
other similar laws  relating to or affecting the rights of creditors  generally;
(b)  the  effect  of  general  principles  of  equity  including,   concepts  of
materiality,  reasonableness,  good  faith and the  possible  unavailability  of
specific performance,  injunctive relief or other equitable remedies, regardless
of whether considered in a proceeding in equity or at law, and (c) the effect of
public  policy  or  applicable  laws  or  equitable   principles   limiting  the
enforceability of indemnification or contribution provisions.

                          (iv)  No  consent,  authorization,   approval,  order,
registration,  license,  certificate,  or permit of or from, or  declaration  or
filing with, any Federal,  state,  local,  or other  governmental  or regulatory
authority or any court or other tribunal having jurisdiction

over the  Company or the  Delaware  Subsidiary  is required  for the  execution,
delivery,  or  performance  by the Company or the  Delaware  Subsidiary  of this

Act which have been made prior to the Closing Date and consents, authorizations,
approvals,  orders,  certificates  or  permits  of  and  from  state  securities
authorities under state "blue sky" or securities laws.


                          (v) The  execution,  delivery and  performance of this
Agreement  and  the  Representative's   Warrant  and  the  consummation  of  the
transactions  set forth thereby will not (a) violate,  result in a breach of any
of the terms and  provisions  of,  conflict  with,  result  in the  creation  or
imposition of any lien,  charge or encumbrance  upon any properties or assets of
the  Company or the  Delaware  Subsidiary  pursuant to the terms of, or, with or
without the giving of notice or the  passage of time or both,  entitle any party
to terminate  or call a default  under,  any  contract,  agreement,  instrument,
lease,  license,  arrangement  or  understanding  to which  the  Company  or the
Delaware  Subsidiary  is a party or by which its  properties  or  assets  may be
bound, or (b) violate,  result in a breach of, or conflict with, any term of the
certificate of incorporation or by-laws, or other organizational  documents,  of

over the  Company or the  Delaware  Subsidiary  or its  operations,  businesses,
properties or assets.

                          (vi) To the  best of such  counsel's  knowledge  after

matters  of fact,  to the  extent  that they deem  proper,  on  certificates  of

jurisdictions  having custody of documents respecting the corporate existence or
good standing of the Company,  provided  that, in each case,  copies of any such

every  jurisdiction  in which its  ownership,  leasing,  licensing or use of its

Material  Adverse  Effect.  The  Bioren  Acquisition  has  been  consummated  in
accordance with all applicable laws.

other right calling for the issuance of, any share of capital stock of the Swiss
Subsidiaries  or  any  security  or  other  instrument  which  by its  terms  is
convertible  into,  exercisable  for, or  exchangeable  for capital stock of the
Swiss Subsidiaries.  Except as set forth in the Prospectus, there is outstanding
no security  or other  instrument  which by its terms is  convertible  into,  or

laws relating to or affecting the rights of creditors generally,  (b) the effect
of  general   principles   of  equity   including,   concepts  of   materiality,
reasonableness,   good  faith  and  the  possible   unavailability  of  specific
performance,  injunctive  relief  or other  equitable  remedies,  regardless  of
whether  considered  in a proceeding  in equity or at law, and

Swiss  Subsidiaries  is  in  compliance  with  all  laws,  rules,   regulations,

                          (vii)  There  is no  litigation,  arbitration,  claim,
governmental or other proceeding (formal or informal),  or investigation pending
or threatened with respect to either of the Swiss Subsidiary or their respective
operations, businesses, properties or assets.

stockholders' equity of the Company and its Subsidiaries,  and as of a specified
date not more than five (5) business days prior to the date of such letter,  any
changes  in the  capital  stock  or  long-term  debt  of  the  Company  and  its
Subsidiaries,  in each case,  as  compared  with the  amounts  shown in the most
recent balance sheet presented in the Registration Statement and the Prospectus,
or (D) that during the period from March 31, 1996 to the date of the most recent
available  monthly  consolidated  financial  statements  of the  Company and its
Subsidiaries,  there was any decrease, as compared with the corresponding period
in the prior fiscal year,  in net sales or any increase in net loss per share of
the Company,  and during the period from the latest available  monthly financial
statements of the Company  through a specified  date not more than five business
days prior to the date of such letter,  and there was any decrease,  as compared
with the  corresponding  period in the prior fiscal year,  in total  revenues or
increase  in per share  net  loss,  in each  case  except  for any  non-material
decrease or increase, as the case may be; and

                (iv) stating that they have  compared  specific  numerical  data
and  financial  information  pertaining  to the Company and its Subsidiaries set
forth  in  the Registration Statement, which have been specified by you prior to
the  date of this Agreement, to the extent that such data and information may be
derived from the general accounting records of the Company and its Subsidiaries,
and  excluding  any questions requiring an interpretation by legal counsel, with
the  results  obtained from the application of specified readings, inquiries and
other  appropriate procedures (which procedures do not constitute an examination
in  accordance  with  generally  accepted  auditing  standards) set forth in the
letter, and found them to be in agreement.

                (j) The NASD, upon review of the terms of the public offering of
the Shares,  shall not have objected to the Underwriters'  participation in such
offering.

                (k) Prior to or on the  Closing  Date,  the  Company  shall have

                (l) Prior to or on the  Closing  Date,  the  Company  shall have
provided to you copies of the agreements referred to in Section 2(s).

                Any  certificate or other document  signed by any officer of the
Company and delivered  to the  Representative  or to counsel to the Underwriters
shall be deemed a  representative  and warranty by the Company  hereunder to the
Underwriters  as to  the  statements  made  therein.  If  any  condition  to the
Underwriters'  obligations  hereunder to be fulfilled by the Company prior to or
at the Closing Date or any  Additional  Closing Date, as the case may be, is not
so fulfilled,  you may terminate this Agreement or, if you so elect,  in writing
waive any such  conditions  which have not been fulfilled or extend the time for
their fulfillment.


        8.     Indemnification and Contribution.

                (a) The Company  and each  Subsidiary,  jointly  and  severally,
agrees to indemnify and hold harmless each Underwriter, its officers, directors,
partners,  employees,  agents and counsel, and each person, if any, who controls
any Underwriter  within the meaning of Section 15 of the Act or Section 20(a) of
the Exchange Act, against any and all loss, liability, claim, damage and expense
whatsoever  (which  shall  include,  for all purposes of this Section 8, but not
limited  to,  attorneys'  fees and any and all  expense  whatsoever  incurred in
investigating,  preparing  or  defending  against any  litigation,  commenced or
threatened,  or any  claim  whatsoever  whether  or not in  connection  with any
litigation in which an indemnified party is a party and whether or not involving
a third party claim and any and all amounts paid in  settlement  of any claim or
litigation), joint or several, as to which they or any of them may be subject 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) the
Registration Statement,  any Preliminary Prospectus,  or the Prospectus (as from
time to time amended and  supplemented),  or any amendment or supplement thereto
or (B) any application or other document or communication  (for purposes of this
Section 8, 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 qualify the Shares under the "blue
sky" or securities  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 as stated in
Section  8(b) by any  Underwriter  through you  expressly  for  inclusion in the
Registration Statement,  any Preliminary Prospectus,  or the Prospectus,  or any
amendment or supplement



                                       30

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
Agreement.  The  foregoing  agreement to  indemnify  shall be in addition to any
liability the Company may otherwise have,  including  liabilities  arising under
this Agreement.

         If  any  action  is  brought  against  any  Underwriter  or  any of its
officers, directors,  partners, employees, agents or counsel, or any controlling
persons  of any  Underwriter  (an  "indemnified  party")  in  respect  of  which
indemnity may be sought against the Company or any of the Subsidiaries  pursuant
to the foregoing  paragraph,  such  indemnified  party or parties shall promptly
notify the Company and its  Subsidiaries  in writing of the  institution of such
action  (but the  failure to so notify,  shall not relieve the Company or any of
its  Subsidiaries  from any liability  they may have other than pursuant to this
Section 8(a)) and the Company and its  Subsidiaries  shall  promptly  assume the
defense of such action, including, without limitation, the employment of counsel
satisfactory  to such  indemnified  party or parties  and  payment of  expenses.
Notwithstanding the foregoing,  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,  or (ii)
the  Company  shall not have  promptly  employed  counsel  satisfactory  to such
indemnified  party or parties to have  charge of the  defense of such  action or
within a reasonable time after notice of  commencement  of the action,  or (iii)
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 in addition 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. Anything in this paragraph
to the contrary  notwithstanding,  the Company and its Subsidiaries shall not be
liable for any  settlement  of any such  claim or action  effected  without  its
written consent, which consent shall not be unreasonably  withheld.  Neither the
Company nor any  Subsidiary  shall,  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
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.  The Company and each  Subsidiary  agrees promptly to
notify the  Representative  of the commencement of any litigation or proceedings
against the Company or any  Subsidiary  or any of its  officers or  directors in
connection  with  the  sale  of the  Shares,  the  Registration  Statement,  any
Preliminary  Prospectus,  or the  Prospectus,  or any  amendment  or  supplement
thereto, or any application or any of the Subsidiaries and each Subsidiary.

         (b) Each  Underwriter,  severally and not jointly,  agrees to indemnify
and hold harmless the Company and any Subsidiary,  each director of the Company,
each  officer of the Company who shall have signed the  Registration  Statement,
and each other  person,  if any, who controls the Company  within the meaning of
Section 15 of the Act or Section  20(a) of the



                                       31

Exchange Act, to the same extent as the foregoing indemnity from the Company and
each  Subsidiary  to the several  Underwriters  in Section  8(a),  but only with
respect  to  statements  made in the  Registration  Statement,  any  Preliminary
Prospectus,  or the Prospectus (as from time to time amended and  supplemented),
or any amendment or supplement thereto, or in any application, in reliance upon,
and in conformity with, written  information  furnished to the Company as stated
in this Section 8(b) with respect to the Underwriters  through you expressly for
inclusion in the  Registration  Statement,  any Preliminary  Prospectus,  or the
Prospectus,  or any amendment or supplement thereto,  or in any application,  as
the case may be;  provided,  however,  that any obligation of any Underwriter to
provide  indemnity  under the  provisions  of this  Section 8(b) shall not be in
excess of the  underwriting  discount and  commission  applicable  to the Shares
purchased by such Underwriter hereunder. For all purposes of this Agreement, the
Company and each  Subsidiary  acknowledges  that the statements set forth in the
fourth and  penultimate  paragraphs  under the caption  "Underwriting",  as they
relate to the selling concession and reallowance and the history of LT Lawrence,
constitute  the only  information  furnished in writing by, or on behalf of, any
Underwriter  expressly  for  inclusion  in  the  Registration   Statement,   any
Preliminary  Prospectus,  or the  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 Subsidiary or any other person so indemnified
based  on  the  Registration  Statement,  any  Preliminary  Prospectus,  or  the
Prospectus,  or any amendment or supplement thereto, or any application,  and in
respect of which  indemnity may be sought  against any  Underwriter  pursuant to
this Section 8(b), any Underwriter shall have the rights and duties given to the
Company and its  Subsidiaries,  and the Company  and its  Subsidiaries  and each
other  person so  indemnified  shall have the  rights  and  duties  given to the
indemnified parties, by the provisions of Section 8(a).

         (c)  To  provide  for  just  and  equitable  contribution,  if  (i)  an
indemnified party makes a claim for indemnification  pursuant to Section 8(a) or
8(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 Act, the Exchange Act, or otherwise, then the Company and
its  Subsidiaries  (including for this purpose any  contribution  made by, or on
behalf of, any  director of the  Company,  any officer of the Company who signed
the Registration  Statement,  and any controlling person of the Company), as one
entity and the Underwriters  (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, so that the Underwriters are responsible for the proportion
thereof equal to the percentage  which the  underwriting  discount per Share set
forth on the cover of the Prospectus  represents of the initial public  offering
price per share set forth on the cover page of the  Prospectus  and the  Company
and its  Subsidiaries  are  responsible  for the  remaining  portion;  provided,
however,  that if  applicable  law does not permit such  allocation,  then other
relevant equitable considerations, such as the relative fault of the Company and
its  Subsidiaries,  on the one hand,  and the  Underwriters,  on the  other,  in
connection  with the facts which resulted in such losses,  liabilities,  claims,
damages, and expenses shall also be considered. The  relative



                                       32
<PAGE>
<PAGE>



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 any  Subsidiary,  on the one hand, or by
the  Underwriters,  on the other, 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,  each Subsidiary
and the  Underwriters  agree  that it would be  unjust  and  inequitable  if the
respective obligations of the Company and its Subsidiaries, on the one hand, and
the Underwriters,  on the other, for contribution were determined by pro rata or
per capita allocation of the aggregate losses, liabilities,  claims, damages and
expenses  (even if the  Underwriters  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
8(c). No person guilty of a fraudulent  misrepresentation (within the meaning of
Section 11(f) of the Act) shall be entitled to contribution  from any person who
is not guilty of such fraudulent misrepresentation. For purposes of this Section
8(c),  each person,  if any, who controls an  Underwriter  within the meaning of
Section 15 of the Act or Section  20(a) of the  Exchange  Act and each  officer,
director,  partner,  employee,  agent, and counsel of any Underwriter shall have
the same rights to contribution as such Underwriter and each person, if any, who
controls  the  Company  within  the  meaning of Section 15 of the Act or Section
20(a) of the Exchange Act, each officer of the Company who shall have signed the
Registration Statement,  and each director of the Company shall have same rights
to contribution  as the Company,  subject in each case to the provisions of this
Section 8(c). Anything in this Section 8(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  8(c) is
intended to supersede any right to contribution under the Act, the Exchange Act,
or otherwise.


        9.     Default by an Underwriter.

                (a) If any Underwriter or  Underwriters  shall default in its or
their obligation to purchase Firm Shares or Additional Shares hereunder,  and if
the Firm Shares or Additional  Shares with respect to which such default relates
does not (after giving effect to  arrangements,  if any, made by you pursuant to
subsection  (b) below)  exceed in the  aggregate  10% of the number of shares of
Firm Shares or  Additional  Shares,  as the case may be, which all  Underwriters
have agreed to purchase hereunder, then such shares of Firm Shares or Additional
Shares to which the default  relates  shall be purchased  by the  non-defaulting
Underwriters in proportion to their  respective  proportions by which the number
of Firm Shares set forth  opposite their  respective  names in Schedule I hereto
bear to the  aggregate  number of shares of Firm Shares set forth  opposite  the
names of all the non-defaulting Underwriters.

                (b) In the event that such  default  relates to more than 10% of
the Firm  Shares  or  Additional  Shares,  as the  case may be,  you may in your
discretion  arrange for yourself or for another party or parties  (including any
non-defaulting  Underwriter or Underwriters  who so agree) to purchase such Firm
Shares or Additional  Shares,  as the case may be, to which such



                                       33
<PAGE>
<PAGE>



default relates on the terms contained  herein. In the event that within two (2)
business  days after such a default you do not  arrange for the  purchase of the
Firm  Shares or  Additional  Shares,  as the case may be, to which such  default
relates  as  provided  in this  Section 9, this  Agreement  or, in the case of a
default  with  respect  to  the  Additional   Shares,  the  obligations  of  the
Underwriters to purchase Additional Shares, shall thereupon  terminate,  without
liability on the part of the Company with respect  thereto  (except in each case
as provided in Sections 6, 8 and 11 hereof) or the several  Underwriters (except
as provided in Sections 8 and 11 hereof),  but nothing in this  Agreement  shall
relieve a defaulting  Underwriter or Underwriters of its or their liability,  if
any, to the other several  Underwriters,  and the Company for damages occasioned
by its or their default hereunder.

         (c) In the event that the Firm Shares or Additional Shares to which the
default relates are to be purchased by the non-defaulting  Underwriters,  or are
to be purchased  by another  party or parties as  aforesaid,  you or the Company
shall have the right to postpone the Closing Date or Additional Closing Date, as
the case may be, for a period, not exceeding five (5) business days, in order to
effect  whatever  changes  may  thereby be made  necessary  in the  Registration
Statement or the Prospectus or in any other documents and arrangements,  and the
Company agrees to file promptly any amendment or supplement to the  Registration
Statement or the Prospectus which, in the opinion of Underwriters'  counsel, may
thereby be made necessary or advisable.  The term  "Underwriter" as used in this
Agreement  shall  include any party  substituted  under this Section 9 with like
effect as if it had  originally  been a party to this  Agreement with respect to
such Firm Shares and the Additional Shares.


         10.   Representations   and   Agreements  to  Survive   Delivery.   All
representations,   warranties,   covenants  and  agreements  contained  in  this
Agreement  shall be  deemed to be  representations,  warranties,  covenants  and
agreements  at the  Closing  Date  and any  Additional  Closing  Date,  and such
representations,  warranties,  covenants and agreements of the Underwriters, the
Company and its Subsidiaries,  including the agreements  contained in Section 5,
the indemnity and contribution  agreements  contained in Section 8, shall remain
operative and in full force and effect regardless of any investigation  made by,
or on behalf of, the Underwriters or any indemnified person, or by, or on behalf
of, the Company, each Subsidiary or any person or entity which is entitled to be
indemnified under Section 8(b), and shall survive delivery of the Firm Shares or
the Additional Shares. In addition, the provisions of Sections 6, 8, 10, 11, 13,
15 and 16 shall survive termination of this Agreement,  whether such termination
occurs before or after the Closing Date or any Additional Closing Date.


         11. Effective Date of This Agreement and Termination Thereof.

                (a) This Agreement shall become  effective upon the later of (i)
9:30 A.M.,  New York City local time,  on the first full  business day following
the day on which the Registration  Statement  becomes effective under the Act or
(ii) the execution of this Agreement (the "Effective Date").


                                       34
<PAGE>
<PAGE>




                (b) If the  purchase  price  of the  Firm  Shares  has not  been
determined as provided for in Section 3 prior to 4:30 P.M.,  New York City local
time,  on the third full  business day after the date on which the  Registration
Statement was declared effective under the Act, this Agreement may be terminated
at any time  thereafter  either by you or by the Company by giving notice to the
other unless before such  termination the purchase price for the Firm Shares has
been so  determined.  If the  purchase  price  of the Firm  Shares  has not been
determined  prior to 4:30  P.M.,  New York City  local  time,  on the tenth full
business  day after the date on which the  Registration  Statement  was declared
effective under the Act, this Agreement shall automatically terminate forthwith.

                (c) In  addition  to  the  right  to  terminate  this  Agreement
pursuant  to  Section 7  hereof,  you shall  have the  right to  terminate  this
Agreement at any time prior to the Closing Date or any Additional  Closing Date,
as the case may be,  by giving  notice to the  Company  if (i) any  domestic  or
international  event,  act or occurrence  has materially  disrupted,  or in your
opinion will in the immediate future materially disrupt, the securities markets;
or (ii)  if  there  shall  have  been a  general  suspension  of,  or a  general
limitation on prices for,  trading in securities on the New York Stock Exchange,
the American  Stock  Exchange,  the Nasdaq  Stock  Market or any regional  stock
exchange or in the over-the-counter market; or (iii) if there shall have been an
outbreak  or  increase in the level of major  hostilities  or other  national or
international  calamity;  or (iv) if a banking moratorium has been declared by a
state or federal  authority;  or (v) if a moratorium in foreign exchange trading
by major  international  banks or persons  has been  declared;  or (vi) if there
shall have been a material  interruption  in the mail  service or other means of
communications  within  the  United  States;  or  (vii)  if the  Company  or any
Subsidiary shall have sustained a material or substantial  loss by fire,  flood,
accident, hurricane,  earthquake, theft, sabotage or other calamity or malicious
act  which,  whether or not such loss shall  have been  insured,  will,  in your
opinion,  make it inadvisable to proceed with the offering,  sale or delivery of
the Shares; or (viii) if any material governmental  restrictions shall have been
imposed on trading in  securities  in  general,  which  restrictions  are not in
effect on the date  hereof;  or (ix) if there shall be passed by the Congress of
the United States or by any state  legislature  or any  equivalent  governmental
bodies  in  Switzerland  or  Germany  any  act or  measure,  or  adopted  by any
governmental  body  or  authoritative  accounting  institute  or  board,  or any
governmental  executive  orders,  rules or  regulations,  which you  believe are
likely to have a material adverse effect on the business, financial condition or
financial  statements of the Company or any  Subsidiary or the market for any of
the  Company's  securities;  or (x) if there  shall have been such change in the
market for  Company's  securities  or  securities  in  general or in  political,
financial or economic  conditions as in your judgment  makes it  inadvisable  to
proceed  with  the  offering,  sale  and  delivery  of the  Firm  Shares  or the
Additional  Shares,  as the  case  may  be,  on the  terms  contemplated  by the
Prospectus;  or (xi) the Company or any Subsidiary shall have failed, refused or
been unable to perform in any material  respect any  agreement or its part to be
performed  hereunder;  or (xii) if in your judgment any material  adverse change
shall have occurred since the respective dates as of which  information is given
in the Registration  Statement or the Prospectus in the condition  (financial or
otherwise)  of the  Company or any  Subsidiary,  whether  or not  arising in the
ordinary course of business.

                (d) If  you  elect  to  prevent  this  Agreement  from  becoming
effective,  as  provided  in this  Section 11, or to  terminate  this  Agreement
pursuant to Section 7 or this  Section 11, you shall  notify the Company and its
Subsidiaries promptly by telephone, telex or telegram,  confirmed by letter. If,

Subsidiaries  shall  notify  you  promptly  by  telephone,  telex  or  telegram,
confirmed by letter.

                (e) Anything in this  Agreement to the contrary  notwithstanding
other than Section 11(f), if this Agreement shall not become effective by reason
of an election  pursuant to this Section 11 or if this Agreement shall terminate
or shall otherwise not be carried out within the time specified herein by reason
of any  failure on the part of the  Company  or any  Subsidiary  to perform  any
covenant or  agreement or satisfy any  condition  of this  Agreement by it to be
performed or satisfied,  the sole liability of the Company and its  Subsidiaries
to you, in addition to the obligations  the Company and each Subsidiary  assumed
pursuant  to  Section  6,  will  be  to  reimburse  the  Underwriters  for  such
out-of-pocket  expenses  (including the fees and  disbursements of Underwriters'
counsel) as shall have been incurred by them in connection  with this  Agreement
or the  proposed  offer,  sale and  delivery of the Shares,  and upon demand the
Company and each  Subsidiary  agrees to pay promptly the full amount  thereof to
you.

                (f) Notwithstanding any election hereunder or any termination of
this Agreement,  and whether or not this Agreement is otherwise carried out, the
provisions  of Sections 6, 8, 10 and 13 shall not be in any way affected by such
election or  termination  or failure to carry out the terms of this Agreement or
any part hereof.

Subsidiaries  and the  persons  and  entities  referred  to in Section 8 who are

         14. Partial Unenforceability. The invalidity or unenforceability of any

the  same  document  binding  on all of the  parties  thereto.  Transmission  by
telecopier  of an  executed  counterpart  of this  Agreement  shall be deemed to

                            CERTIFICATE OF CORRECTION
                                     OF THE
                RESTATED AND AMENDED CERTIFICATE OF INCORPORATION
                                       OF
                                  BIGMAR, INC.


        Bigmar, Inc., a Delaware corporation,  pursuant to Section 103(f) of the
General Corporation Law of the State of Delaware, does hereby certify:
        FIRST: That the Restated and Amended  Certificate of Incorporation which
was filed  with the  Secretary  of State of  Delaware  on April  16,  1996 is an
inaccurate  record in certain respects of the nature of dealing with disposition
of fractional shares and of the nature of the Stock Split.
        SECOND:  That said Restated and Amended Certificate of Incorporation was
inaccurate  in that the second  sentence  of  paragraph  (d) of  Article  Fourth
states:  "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." and that the third paragraph  thereof
states  "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."
        THIRD:  That the second  sentence of paragraph (d) of Article  Fourth in
correct form should read as follows:  "No fractional shares shall be issued, and
the Corporation  shall pay to such holder an amount of cash equal to the product
of the  fraction of a


<PAGE>

<PAGE>



share of New  Common  Stock to which such  holder  otherwise  would be  entitled
multiplied  by the fair value of such share of New Common Stock as determined in
good faith by the Board of Directors of the Corporation."
        FOURTH:  That the third  sentence of paragraph (d) of Article  Fourth in
correct form should read as follows: "Effective at the close of business on such
date, each certificate representing shares of Outstanding Common shall be deemed
to represent  the  quotient of the number of shares of Common  Stock  previously
represented by such certificate divided by 2.105263."

        IN   WITNESS   WHEREOF,  Bigmar,  Inc.  has  caused  this Certificate of
Correction  to  be  executed  by  John  G.  Tramontana, its President, and Chief
Executive Officer, under its corporate seal this 28th day of May, 1996.

                         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  or  partners  of the Holder (or the  officers  or partners of any such
partner),  (ii) any other underwriting firm or member of the selling group which
participated  in the  Company's  initial  public  offering of Common Stock which
commenced on June __, 1996 (or the officers or partners of any such firm), (iii)
any successor to the Holder or the officers or partners of such successor,  (iv)
any  purchaser  of  substantially  all of the  assets of the  Holder,  or (v) 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

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-

<PAGE>
<PAGE>



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
October 12, 1996 and ending on October 12,  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


                                       -8-

<PAGE>
<PAGE>



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; 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

                            INDEMNIFICATION AGREEMENT


               This agreement, made and entered into this ____ day of _______,
1996 ("Agreement"), by and between Bigmar, Inc., a Delaware corporation (the
"Corporation"), and ______________ ("Indemnitee"):

                                           RECITALS

               WHEREAS, highly competent persons are becoming more reluctant to
serve as directors, officers or in other capacities unless they are provided
with adequate protection through insurance or adequate indemnification against
inordinate risks of claims and actions against them arising out of their service
to and activities on behalf of the Corporation; and

               WHEREAS, the current difficulty of obtaining adequate insurance
and the uncertainties relating to indemnification have increased the difficulty
of attracting and retaining such persons; and

               WHEREAS, the Board of Directors of the Corporation has determined
that the inability to attract and retain such persons is detrimental to the best
interests of the Corporation's stockholders and that the Corporation should act
to assure such persons that there will be increased certainty of such
protection in the future; and

               WHEREAS, it is reasonable, prudent and necessary for the
Corporation contractually to obligate itself to indemnify such persons to the
fullest extent permitted by applicable law so that they will serve or continue
to serve the Corporation free from undue concern that they will not be so
indemnified; and

               WHEREAS, Indemnitee is willing to serve, continue to serve and to
take on additional service for or on behalf of the Corporation on the condition
that Indemnitee be so indemnified;

               NOW, THEREFORE, in consideration of the premises and
the covenants contained herein, the Corporation and Indemnitee
do
hereby covenant and agree as follows:

                                    ARTICLE I

                                   Definitions

form) promulgated under the Securities Exchange Act of 1934 (the "Act"), whether
or not the Corporation is then subject to such reporting requirement; provided,
however, that, without limitation, such a Change in Control shall be deemed to
have occurred if after the Effective Date (i) any "person" (as such term is used
in Sections 13(d) and 14(d) of the Act) is or becomes the "beneficial owner" (as
defined in Rule 13d-3 under the Act), directly or indirectly, of securities of
the Corporation representing 20% or more of the combined voting power of the
Corporation's then outstanding securities without the prior approval of at
least two-thirds of the members of the Board in office immediately prior to
such person attaining such percentage interest; (ii) the Corporation is a party
to a merger, consolidation, sale of assets or other reorganization, or a proxy
contest, as a consequence of which members of the Board in office immediately
prior to such transaction or event constitute less than a majority of the Board
thereafter; or (iii) during any period of two consecutive years, individuals who
at the beginning of such period constituted the Board (including for this
purpose any new director whose election or nomination for election by the
Corporation's stockholders was approved by a vote of at least two-thirds of the
directors then still in office who were directors at the beginning of such
period) cease for any reason to constitute at least a majority of the Board.

               1.03 "Corporate Status" describes the status of a person who is

               1.09 "Independent Counsel" means a law firm, or a member of a law
firm, that is experienced in matters of corporation law and neither presently
is, nor in the past five years has been, retained to represent: (i) the
Corporation or Indemnitee in any matter material to either such party, or (ii)
any other party to the Proceeding giving rise to a claim for indemnification

               4.02 Proceedings Other Than Proceedings by or in the Right of the
Corporation. Indemnitee shall be entitled to the rights of indemnification
provided in this Section 4.02 if, by reason of Indemnitee's Corporate Status,
Indemnitee is, or is threatened to be made, a party to any Proceeding, other
than a Proceeding by or in the right of the Corporation. Indemnitee shall be
indemnified against fees, Expenses, judgments, penalties, fines and amounts paid
in settlement actually and reasonably incurred by Indemnitee or on Indemnitee's
behalf in connection with such Proceeding or any claim, issue or matter therein,
if Indemnitee acted in Good Faith.

               4.03 Proceedings by or in the Right of the Corporation.

<PAGE>



matter in such Proceeding as to which Indemnitee shall have been adjudged to be
liable to the Corporation, unless and only to the extent that the Court of
Chancery of the State of Delaware or the court in which such Proceeding shall
have been brought or, if no action was brought, any court of competent
jurisdiction determines upon application that, despite the adjudication of
liability but in view of all the circumstances of the case, the Indemnitee is
fairly and reasonably entitled to indemnity for such portion of the settled
amount and Expenses as such court deems proper.

               4.04 Indemnification of a Party Who is Wholly or Partly
Successful. Notwithstanding any other provision of this Agreement, to the
extent that Indemnitee is, by reason of Indemnitee's Corporate Status, a party
to and is successful, on the merits or otherwise, in any Proceeding, Indemnitee
shall be indemnified to the maximum extent permitted by law, against all
Expenses, judgments, penalties, fines, and amounts paid in settlement, actually
and reasonably incurred by Indemnitee or on Indemnitee's behalf in connection
therewith. If Indemnitee is not wholly successful in such Proceeding but is
successful, on the merits or otherwise, as to one or more but less than all
claims, issues or matters in such Proceeding, the Corporation shall indemnify
Indemnitee to the maximum extent permitted by law, against all Expenses actually
and reasonably incurred by Indemnitee or on Indemnitee's behalf in connection
with each successfully resolved claim, issue or matter. For purposes of this
Section 4.04 and without limitation, the termination of any claim, issue or
matter in such a Proceeding by dismissal, with or without prejudice, shall be
deemed to be a successful result as to such claim, issue or matter.

               4.05 Indemnification for Expenses of a Witness. Notwithstanding
any other provision of this Agreement, to the extent that Indemnitee is, by
reason of Indemnitee's Corporate Status, a witness in any Proceeding, Indemnitee
shall be indemnified against all Expenses actually and reasonably incurred by
Indemnitee or on Indemnitee's behalf in connection therewith.

               Notwithstanding any provision to the contrary in Article VI, the
Corporation shall advance all reasonable Expenses which, by reason of
Indemnitee's Corporate Status, were charged to or incurred by or on behalf of
Indemnitee in connection with any Proceeding, within twenty days after the
receipt by the Corporation of a statement or statements from Indemnitee
requesting such advance or advances whether prior to or after final disposition
of such Proceeding. Such statement or statements shall reasonably evidence

Indemnitee has requested indemnification.

               6.02 Method of Determination. A determination (if required by
applicable law) with respect to Indemnitee's entitlement to indemnification
shall be made by the Board by a majority vote of a quorum consisting of
Disinterested Directors. In the event that a quorum of the Board consisting of
Disinterested Directors is not obtainable or, even if obtainable, such quorum of
Disinterested Directors so directs, the determination shall be made by
Independent Counsel in a written opinion to the Board, a copy of which shall be
delivered to Indemnitee, or by the stockholders of the Corporation, as
determined by such quorum of Disinterested Directors or by a quorum of the
Board, as the case may be. If a Change in Control has occurred and Indemnitee so
requests, the determination shall be made by Independent Counsel in a written
opinion to the Board, a copy of which shall be delivered to Indemnitee.

               6.03 Selection, Payment, Discharge of Independent Counsel. In the
event the determination of entitlement to indemnification is to be made by
Independent Counsel pursuant to Section 6.02 of this Agreement, the Independent
Counsel shall be selected, paid, and discharged in the following manner:

                      (a)    The Independent counsel shall be selected by the
                             Board, and the Corporation shall give written
                             notice to Indemnitee advising Indemnitee of the
                             identity of the Independent Counsel so selected.

                      (b)    Following the initial selection described in clause
                             (a) of this Section 6.03, Indemnitee may, within
                             seven days after such written notice of selection
                             has been given, deliver to the Corporation a
                             written objection to 

                                       -6-

<PAGE>



                             such selection. Such objection may be asserted
                             only on the ground that the Independent Counsel so
                             selected does not meet the requirements of
                             "Independent Counsel" as defined in Section 1.09 of
                             this Agreement, and the objection shall set forth
                             with particularity the factual basis of such
                             assertion. Absent a proper and timely objection,
                             the person so selected shall act as Independent
                             Counsel. If such written objection is made, the
                             Independent Counsel so selected may not serve as
                             Independent Counsel unless and until a court has
                             determined that such objection is without merit or
                             Indemnitee has delivered a written withdrawal of
                             such objection to the Corporation.

                      (c)    Either the Corporation or Indemnitee may petition
                             the Court of Chancery of the State of Delaware or
                             other court of competent jurisdiction if the
                             parties have been unable to agree on the selection
                             of Independent Counsel (if applicable) within 20
                             days after submission by Indemnitee of a written
                             request for indemnification pursuant to Section
                             6.01 of this Agreement. Such petition may request a
                             determination whether an objection to the party's
                             selection is without merit and/or seek the
                             appointment as Independent Counsel of a person
                             selected by the Court or by such other person as
                             the Court shall designate. A person so appointed
                             shall act as Independent Counsel under Section 6.02
                             of this Agreement.

                      (d)    The Corporation shall pay any and all reasonable
                             fees and expenses of Independent Counsel incurred
                             by such Independent Counsel acting pursuant to this
                             Agreement, and the Corporation shall pay all 
                             reasonable fees and expenses incident to the
                             procedures of this Section 6.03, regardless of the
                             manner in which such Independent Counsel was
                             selected or appointed.

                      (e)    Upon the due commencement of any judicial
                             proceeding or arbitration pursuant to Section
                             8.01(c) of this Agreement, Independent Counsel
                             shall be discharged and relieved of any further
                             responsibility in such capacity (subject to the
                             applicable standards of professional conduct then
                             prevailing).

               6.04 Cooperation. Indemnitee shall cooperate with the person,
persons or entity making the determination with respect to Indemnitee's
entitlement to indemnification under this Agreement, including providing to
such person, persons or entity upon reasonable advance request any documentation
or information which is not privileged or otherwise protected from disclosure
and which is reasonably available to Indemnitee and reasonably necessary to such
determination. Any costs or expenses (including attorneys' fees and
disbursements) incurred by Indemnitee in so cooperating with the person, persons
or entity making such determination shall be borne by the Corporation
(irrespective of the determination as to Indemnitee's entitlement to
indemnification) and the Corporation hereby indemnifies and agrees to hold
Indemnitee harmless therefrom.

               6.05 Payment. If it is determined that Indemnitee is entitled to
indemnification, payment to Indemnitee shall be made within ten (10) days after
such determination.

                                   ARTICLE VII

                 Presumptions and Effect of Certain Proceedings

               7.01 Burden of Proof. In making a determination with respect to
entitlement to indemnification hereunder, the person or persons or entity making
such determination shall presume that Indemnitee is entitled to indemnification
under this Agreement if Indemnitee has submitted a request for indemnification
in accordance with Section 6.01 of this Agreement, and the Corporation shall
have the burden of proof to overcome that presumption in connection with the
making by any person, persons or entity of any determination contrary to that
presumption.

               7.02 Effect of Other Proceedings. The termination of any
Proceeding or of any claim, issue or matter therein, by judgment, order,
settlement or conviction, or upon a plea of nolo contendere or its equivalent,
shall not (except as otherwise expressly provided in this Agreement) of itself
adversely affect the right of Indemnitee to indemnification or create a
presumption that Indemnitee did not act in Good Faith.

               7.03 Reliance as Safe Harbor. For purposes of any determination
of Good Faith, Indemnitee shall be deemed to have acted in Good Faith if
Indemnitee's action is based on the records or books of account of the
Enterprise, including financial statements, or on information supplied to
Indemnitee by the officers of the Enterprise in the course of their duties, or
on the advice of legal counsel for the Enterprise or on information or records
given or reports made to the Enterprise by an independent certified public
accountant or by an appraiser or other expert selected with reasonable care by
the Enterprise. The provisions of this Section 7.03 shall not be deemed to be
exclu-

                                       -8-
<PAGE>
<PAGE>

sive or to limit in any way the other circumstances in which the Indemnitee may
be deemed to have met the applicable standard of conduct set forth in this
Agreement.

               7.04 Actions of Others. The knowledge and/or actions, or failure
to act, of any director, officer, agent or employee of the Enterprise shall not
be imputed to Indemnitee for purposes of determining the right to
indemnification under this Agreement.

                                  ARTICLE VIII

                             Remedies of Indemnitee


               8.01 Application. This Article VIII shall apply in the event of a
Dispute. For purposes of this Article, "Dispute", shall mean any of the
following events:

                      (a)    a determination is made pursuant to Article VI of
                             this Agreement that Indemnitee is not entitled to
                             indemnification under this Agreement;

                      (b)    advancement of Expenses is not timely made
                             pursuant to Article V of this Agreement;

                      (c)    the determination of entitlement to be made
                             pursuant to Section 6.02 of this Agreement had not
                             been made within 90 days after receipt by the
                             Corporation of the request for indemnification;

                      (d)    payment of indemnification is not made pursuant to
                             Section 4.05 of this Agreement within ten (10) days
                             after receipt by the Corporation of written
                             request therefor; or

                      (e)    payment of indemnification is not made within ten
                             (10) days after a determination has been made that
                             Indemnitee is entitled to indemnification pursuant
                             to Article VI of this
                             Agreement.

               8.02 Adjudication. In the event of a Dispute, Indemnitee shall
be entitled to an adjudication in the Court of Chancery of the State of Delaware
or in any other court of competent jurisdiction, of Indemnitee's entitlement to
such indemnification and advancement of Expenses. Alternatively, Indemnitee, at
Indemnitee's option, may seek an award in arbitration to be conducted by a
single arbitrator, pursuant to the rules of the American Arbitration
Association. Indemnitee shall commence such proceeding seeking an adjudication
or an award in arbitration within 180 days following the date on which
Indemnitee first has

                                       -9-

<PAGE>
<PAGE>


the right to commence such proceeding pursuant to this Section 8.02. The
Corporation shall not oppose Indemnitee's right to seek any such adjudication or
award in arbitration.

               8.03 De Novo Review. In the event that a determination shall have
been made pursuant to Article VI of this Agreement that Indemnitee is not
entitled to indemnification, any judicial proceeding or arbitration commenced
pursuant to this Article VIII shall be conducted in all respects as a de novo
trial, or arbitration, on the merits and Indemnitee shall not be prejudiced by
reason of that adverse determination. In any such proceeding or arbitration, the
Corporation shall have the burden of proving that Indemnitee is not entitled to
indemnification or advancement of Expenses, as the case may be.

               8.04 Corporation Bound. If a determination shall have been made
pursuant to Article VI of this Agreement that Indemnitee is entitled to
indemnification, the Corporation shall be bound by such determination in any
judicial proceeding or arbitration absent (i) a misstatement by Indemnitee of a
material fact, or an omission of a material fact necessary to make Indemnitee's
statement not materially misleading, in connection with the request for
indemnification, or (ii) a prohibition of such indemnification under applicable
law.

               8.05 Procedures Valid. The Corporation shall be precluded from
asserting in any judicial proceeding or arbitration commenced pursuant to this
Article VIII that the procedures and presumptions of this Agreement are not
valid, binding and enforceable and shall stipulate in any such court or before
any such arbitrator that the Corporation is bound by all the provisions of this
Agreement.

               8.06. Expenses of Adjudication. In the event that Indemnitee,
pursuant to this Article VIII, seeks a judicial adjudication of or an award in
arbitration to enforce Indemnitee's rights under, or to recover damages for
breach of, this Agreement, Indemnitee shall be entitled to recover from the
Corporation and shall be indemnified by the Corporation against, any and all
expenses (of the types described in the definition of Expenses in Section 1.07
of this Agreement) actually and reasonably incurred by Indemnitee in such
adjudication or arbitration, but only if Indemnitee prevails therein. If it
shall be determined in such adjudication or arbitration that Indemnitee is
entitled to receive part but not all of the indemnification of advancement or
expenses sought, the expenses incurred by Indemnitee in connection with such
adjudication or arbitration shall be appropriately prorated.

                                   ARTICLE IX

                     Non-Exclusivity, Insurance, Subrogation


               9.01 Non-Exclusivity. The rights of indemnification and to
receive advancement of Expenses as provided by this Agreement shall not be
deemed exclusive of any other rights to which Indemnitee may at any time be
entitled under applicable law, the Restated Certificate of Incorporation, as
amended, the By-Laws, any agreement, a vote of stockholders or a resolution of
directors, or otherwise. No amendment, alteration, rescission or replacement of
this Agreement or any provision hereof shall be effective as to Indemnitee with
respect to any action taken or omitted by such Indemnitee in Indemnitee's
Corporate Status prior to such amendment, alteration, rescission or replacement.

               9.02 Insurance. The Corporation may maintain an insurance policy
or policies against liability arising out of this Agreement or otherwise.

               9.03 Subrogation. In the event of any payment under this
Agreement, the Corporation shall be subrogated to the extent of such payment to
all of the rights of recovery of Indemnitee, who shall execute all papers
required and take all action necessary to secure such rights, including
execution of such documents as are necessary to enable the Corporation to bring
suit to enforce such rights.

               9.04 No Duplicative Payment. The Corporation shall not be liable
under this Agreement to make any payment of amounts otherwise indemnifiable
hereunder if and to the extent that Indemnitee has otherwise actually received
such payment under any insurance policy, contract, agreement or otherwise.

                                    ARTICLE X

                               General Provisions


10.01 Successors and Assigns. This Agreement shall be binding upon the
Corporation and its successors and assigns and shall inure to the benefit of
Indemnitee and Indemnitee's heirs, executors and administrators.

               10.02 Severability. If any provision or provisions of this
Agreement shall be held to be invalid, illegal or unenforceable for any reason
whatsoever:

                      (a)    the validity, legality and enforceability of
                             the remaining provisions of this Agreement
                             (including, without limitation, each portion
                             of any Section of this Agreement containing any
                             such provision held to be invalid, ille-

                             illegal or unenforceable) shall not in any way be
                             affected or impaired thereby; and

                      (b)    to the fullest extent possible, the provisions of
                             this Agreement (including, without limitation, each
                             portion of any Section of this Agreement containing
                             any such provision held to be invalid, illegal or
                             unenforceable, that is not itself invalid, illegal
                             or unenforceable) shall be construed so as to give
                             effect to the intent manifested by the provision
                             held invalid, illegal or unenforceable.

               10.03 No Adequate Remedy. The parties declare that it is
impossible to measure in money the damages which will accrue to either party by
reason of a failure to perform any of the obligations under this Agreement.
Therefore, if either party shall institute any action or proceeding to enforce
the provisions hereof, such party against whom such action or proceeding is
brought hereby waives the claim or defense that such party has an adequate
remedy at law, and such party shall not urge in any such action or proceeding
the claim or defense that the other party has an adequate remedy at law.

               10.04 Identical Counterparts. This Agreement may be executed in
one or more counterparts, each of which shall for all purposes be deemed to be
an original but all of which together shall constitute one and the same
Agreement. Only one such counterpart signed by the party against whom
enforceability is sought needs to be produced to evidence the existence of this
Agreement.

               10.05 Headings. The headings of the sections of this Agreement
are inserted for convenience only and shall not be deemed to constitute part of
this Agreement or to affect the construction thereof.

               10.06 Modification and Waiver. No supplement, modification or
amendment of this Agreement shall be binding unless executed in writing by both
of the parties hereto. No waiver of any of the provisions of this Agreement
shall be deemed or shall constitute a waiver of any other provisions hereof
(whether or not similar) nor shall such waiver constitute a continuing waiver.

               10.07 Notices. All notices, requests, demands and other
communications hereunder shall be in writing and shall be deemed to have been
duly given if (i) delivered by hand and receipted for by the party to whom said
notice or other communication shall have been directed, or (ii) mailed by

        This AGREEMENT made as of the 15th day of April, 1996, by and between
Bigmar, Inc., a Delaware corporation (hereinafter, "the Employer" or
"Employer"), and John G. Tramontana (hereinafter, "the Executive" or
"Executive").


        1. Commencing on the Effective Date, as hereinafter defined, of this
Agreement, Employer shall employ Executive as President and Chief Executive
Officer to perform the duties normally incident to such positions.

        2. Executive agrees to devote all of Executive's business time, efforts,
skills and attention to fulfill Executive's duties and responsibilities
hereunder faithfully, diligently and competently.

        3. The term of this Agreement shall commence upon the consummation of

        8. Executive will be entitled to four weeks vacation during each

        9. Employer will provide either directly to Executive or on Executive's
behalf, an automobile allowance in the amount of $6,000 for each Twelve-Month

            (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
insurance in any amount or amounts considered advisable but not less than Two
Million 00/100 ($2,000,000) Dollars and that Executive shall have no right,
title or interest therein.

            (c) Executive represents and warrants that, to the best of
Executive's knowledge, Executive is in good health and that, to the best of
Executive's knowledge, Executive will qualify and be acceptable for life

        11. In the event of Executive's death during the term of this Agreement,
this Agreement shall terminate immediately, provided, however, that Executive's
legal representatives shall be entitled to receive the Base Salary which would
otherwise have been due Executive had Executive worked through the end of the
month of Executive's death plus three additional months of the Base Salary for
the Twelve-Month Period in which Executive died.

        12. If during the term of this Agreement, Executive is unable to perform
Executive's duties hereunder on account of illness or other incapacity, and such
illness or other incapacity shall continue for a period of more than three
consecutive months during any Twelve Month Period, Employer shall have the
right, on thirty days' notice to Executive, given after such three month period,
to terminate this Agreement. In the event of any such

                                       -2-

<PAGE>
<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,
this Agreement shall terminate immediately, provided, however, that Employer
shall be obligated to pay Executive the Base Salary had Executive worked through
the last day of the month in which Executive was terminated and four months of
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>
<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 or under Executive's Original Employment
Agreement.

        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.

                                    by Company to reveal such information on a
                                    confidential basis; or

convenient times and upon reasonable prior notice with the Company and the
Company's management, agents, employees and other Medical Advisory Board members
on the Company's projects in the Field, and (b) to attend meetings of the
Medical Advisory Board of the Company, but in no event will such activities take

                                 shall be under any duty, express or implied,
                                 to [name of hospital or entity by which
                                 Advisor is employed] or any other person or
                                 persons, including any sponsor of research at
                                 same, to keep secret, develop or otherwise to
                                 deal with;

                        (b)      Be construed to grant to the Company any
                                 license under any patent or patent
                                 application not expressly assigned or
                                 assignable to Company in accordance
                                 herewith.

                  5. COMPENSATION AND REIMBURSEMENTS. The Company shall
compensate the Advisor $1,000 per annum for consulting

                                       -2-

<PAGE>



services or Medical Advisory Board meetings attended, payable semi-annually
commencing on the earlier to occur of (i) the date which is three days
subsequent to the date on which the Company consummates any initial public
offering of its securities (the "IPO") and (ii) the date which is 180 days
subsequent to the date hereof. The Company shall reimburse the Advisor for all
authorized expenses incurred in performing services under this Agreement. The
Company also will reimburse the Advisor for other travel expenses for
consultation meetings with the executives of the Company or meetings with the
members of the Company's Medical Advisory Board or with other medical or
scientific individuals involved in the development of projects of the Company.

                  6. STOCK OPTION. In consideration hereof, the Company agrees
to grant to the Advisor a non-qualified stock option (the "Option") under the
Company's 1996 Stock Option Plan (the "1996 Plan") to acquire an aggregate of
3,000 unregistered shares of Common Stock of the Company, $.001 par value per
share, substantially in accordance with the terms and conditions of the 1996
Plan. The Option shall vest in three (3) equal installments of 1,000 shares
each, the first, second and third commencing upon the first, second and third
anniversary dates of the IPO, each of which will be exercisable for a period
of three (3) years following the date of vesting. The Option will be subject
in all respects to the 1996 Plan and to any agreements, rules or policies
with respect to which the Advisor is subject.

                  The exercise price per share (the "Exercise Price") of the
Option shall be determined in accordance with the provisions of the 1996 Plan.
The Exercise Price shall be equal to the price per share of the Common Stock in
the IPO as provided in the Registration Statement filed with the Securities and
Exchange Commission (the "Commission") in connection with the IPO.

                  Adjustments may be made in the number or kind of shares of
securities for which the option may be exercised and in the Exercise Price in
accordance with the 1996 Plan.

                  The Advisor agrees that the Advisor will acquire the Option
and, upon exercise of the Option will acquire the shares of Common Stock so
issued, for the Advisor's own account, for investment purposes only, and not for
public resale or distribution of the same. The Advisor will not sell or
otherwise dispose of, directly or indirectly, the Option, or any shares of
Common Stock issuable upon exercise of the Option except in compliance with the
applicable provisions of this Agreement, the 1996 Plan, the Securities Act of
1933, as amended (the "Securities Act"), and the Rules and Regulations of the
Commission promulgated thereunder and the securities laws of any state. The
Advisor understands and acknowledges that neither the Option nor the shares of
Common Stock issuable upon exercise of

                                       -3-

<PAGE>
<PAGE>



the Option have been registered under the Securities Act, or the securities laws
of any state, and that they are being granted and/or sold in reliance upon an
exemption from registration thereunder and that the Advisor's right to sell,
transfer, pledge or otherwise dispose of the Option or the shares of Common
Stock issuable upon exercise of the Option will be limited by the Securities Act
and state securities laws. Each certificate representing shares of Common Stock
acquired upon exercise of the Option will bear a legend reflecting the
foregoing.

                  In the event of the Advisor's death during the term of this
Agreement, this Agreement shall terminate immediately, provided, however, that
the full amount of the Option shall inure to the benefit of and be exercisable
by the Advisor's legal representatives in accordance with the 1996 Plan at any
time within one year following the date of such death or prior to the date on
which the option expires by its terms, whichever occurs first. If this Agreement
is terminated on account of permanent disability of the Advisor, the Advisor may
exercise the full amount of the Option in accordance with the 1996 Plan at any
time within one year from such termination or prior to the date on which the
Option expires by its terms, whichever occurs first. If this Agreement
terminates for any reason other than death or disability, the Option may
generally be exercised by the Advisor, at any time, in accordance with the terms
of the 1996 Plan, within three months after the date of such termination or

                                    by Company to reveal such information on a
                                    confidential basis; or

                                    by written records.

                                 manufacturing process, which the Advisor
                                 shall be under any duty, express or implied,
                                 to [name of hospital or entity by which
                                 Advisor is employed] or any other person or
                                 persons, including any sponsor of research at

                        (b)      Be construed to grant to the Company any
                                 license under any patent or patent

                                 herewith.

services or Scientific Advisory Board meetings attended, payable semi-annually
commencing on the earlier to occur of (i) the date which is three days
subsequent to the date on which the Company consummates any initial public
offering of its securities (the "IPO") and (ii) the date which is 180 days
subsequent to the date hereof. The Company shall reimburse the Advisor for all
authorized expenses incurred in performing services under this Agreement. The
Company also will reimburse the Advisor for other travel expenses for
consultation meetings with the executives of the Company or meetings with the
members of the Company's Scientific Advisory Board or with other medical or
scientific individuals involved in the development of projects of the Company.

                  6. STOCK OPTION. In consideration hereof, the Company agrees
to grant to the Advisor a non-qualified stock option (the "Option") under the
Company's 1996 Stock Option Plan (the "1996 Plan") to acquire an aggregate of
3,000 unregistered shares of Common Stock of the Company, $.001 par value per
share, substantially in accordance with the terms and conditions of the 1996
Plan. The Option shall vest in three (3) equal installments of 1,000 shares
each, the first, second and third commencing upon the first, second and third
anniversary dates of the IPO, each of which will be exercisable for a period
of three (3) years following the date of vesting. The Option will be subject
in all respects to the 1996 Plan and to any agreements, rules or policies
with respect to which the Advisor is subject.

                  The exercise price per share (the "Exercise Price") of the
Option shall be determined in accordance with the provisions of the 1996 Plan.
The Exercise Price shall be equal to the price per share of the Common Stock in
the IPO as provided in the Registration Statement filed with the Securities and
Exchange Commission (the "Commission") in connection with the IPO.

                  Adjustments may be made in the number or kind of shares of
securities for which the option may be exercised and in the Exercise Price in
accordance with the 1996 Plan.

                  The Advisor agrees that the Advisor will acquire the Option
and, upon exercise of the Option will acquire the shares of Common Stock so
issued, for the Advisor's own account, for investment purposes only, and not for
public resale or distribution of the same. The Advisor will not sell or
otherwise dispose of, directly or indirectly, the Option, or any shares of
Common Stock issuable upon exercise of the Option except in compliance with the
applicable provisions of this Agreement, the 1996 Plan, the Securities Act of
1933, as amended (the "Securities Act"), and the Rules and Regulations of the
Commission promulgated thereunder and the securities laws of any state. The
Advisor understands and acknowledges that neither the

                                       -3-
<PAGE>
<PAGE>




Option nor the shares of Common Stock issuable upon exercise of the Option have
been registered under the Securities Act, or the securities laws of any state,
and that they are being granted and/or sold in reliance upon an exemption from
registration thereunder and that the Advisor's right to sell, transfer, pledge
or otherwise dispose of the Option or the shares of Common Stock issuable upon
exercise of the Option will be limited by the Securities Act and state
securities laws. Each certificate representing shares of Common Stock acquired
upon exercise of the Option will bear a legend reflecting the foregoing.

                  In the event of the Advisor's death during the term of this
Agreement, this Agreement shall terminate immediately, provided, however, that
the full amount of the Option shall inure to the benefit of and be exercisable
by the Advisor's legal representatives in accordance with the 1996 Plan at any
time within one year following the date of such death or prior to the date on
which the option expires by its terms, whichever occurs first. If this Agreement
is terminated on account of permanent disability of the Advisor, the Advisor may
exercise the full amount of the Option in accordance with the 1996 Plan at any
time within one year from such termination or prior to the date on which the
Option expires by its terms, whichever occurs first. If this Agreement
terminates for any reason other than death or disability, the Option may
generally be exercised by the Advisor, at any time, in accordance with the terms
of the 1996 Plan, within three months after the date of such termination or
prior to the date on which the Option expires by its terms, whichever occurs
first, as to any shares of Common Stock subject to the Option which the Advisor
was entitled to exercise at the date of such termination. The right of the
Advisor to exercise the Option shall not be assignable or transferable by the
Advisor otherwise than as permitted by the 1996 Plan.

                  Subject to the provisions of this Agreement, the Option may be
exercised by delivery to the Company, at its principal office, directed to the
attention of the Secretary, of a written notice of exercise surrendering for
cancellation the Option, specifying the number of shares being purchased,
accompanied by payment of the Option price in full for shares being purchased.

                  7. RESTRICTIVE COVENANT. The Advisor recognizes that the
Advisor's services and responsibilities are of particular significance to the
Company and agrees, for the term of this Agreement to inform the Company prior
to serving as an employee, consultant, officer, director, partner or owner
(other than the passive ownership of up to 5% of the outstanding securities of
any public company) of any for-profit entity which the Advisor knows or has
reason to believe is competitive with the business or affairs of the Company,
provided the Advisor shall be under no obligation to disclose to the Company the
identity of such entity, and the Company shall, upon being so informed by the

Company, and shall render, at the Company's expense including reasonable
compensation for the Advisor's time involved, such assistance as the Company may
reasonably require in any Patent and Trademark office proceeding or litigation
involving said inventions.

Advisor in the sole performance of the services of the Advisor to the Company
under this Agreement, which invention relates to the Advisor's research at

                                  BIGMAR, INC.
                             1996 STOCK OPTION PLAN


           1.       Purpose of the Plan.

           The purpose of the Bigmar, Inc., 1996 Stock Option Plan (the "Plan")
is to advance the interests of Bigmar, Inc., a Delaware corporation (the
"Company"), by providing an opportunity for ownership of the stock of the
Company by employees, agents and directors of, and consultants to, the Company
and its subsidiaries. By providing such opportunity, the Company seeks to
attract and retain such qualified personnel, and otherwise to provide additional
incentive for grantees to promote the success of its business.

           2.       Stock Subject to the Plan.

           (a) The total number of shares of the authorized but unissued or
treasury shares of the common stock, $.001 par value per share, of the Company
(the "Common Stock") for which options (the "Options") may be granted under the
Plan shall be 300,000, subject to adjustment as provided in Section 14 hereof.

           (b) If an Option granted or assumed hereunder shall expire or
terminate for any reason without having been exercised in full, the unpurchased
shares subject thereto shall again be available for subsequent Option grants
under the Plan.

           (c) Stock issuable upon exercise of an Option may be subject to such
restrictions on transfer, repurchase rights or other restrictions as shall be
determined by the Board of Directors of the Company (the "Board").

           3.       Administration of the Plan.

           (a) The Plan shall be administered by the Board. No member of the
Board shall act upon any matter exclusively affecting any Option granted or to
be granted to himself or herself under the Plan. A majority of the members of
the Board shall constitute a quorum, and any action may be taken by a majority
of those present and voting at any meeting. The decision of the Board as to all
questions of interpretation and application of the Plan shall be final, binding
and conclusive on all persons. The Board, in its sole discretion, may grant
Options to purchase shares of Common Stock, as provided in the Plan. The Board
shall have authority, subject to the express provisions of the Plan, to construe
the respective Option agreements and the Plan, to prescribe, amend and rescind
rules and regulations relating to the Plan, to determine the terms and
provisions of the respective Option agreements, which may but need not be
identical, and to make all other determinations in the judgment of the Board
necessary or desirable for the administration of the Plan. The Board may correct
any defect or supply any omission or reconcile any inconsistency in the Plan or
in any Option agreement in the manner and to the extent it shall deem expedient
to implement the Plan and shall be the sole and final judge of such expediency.
No director shall be liable for any action or determination made in good faith.
The Board, in its discretion, may delegate its power, duties and
responsibilities to a committee, consisting of two


<PAGE>
<PAGE>



or more members of the Board, all of whom are "disinterested persons" (as
hereinafter defined). If a committee is so appointed, all references to the
Board herein shall mean and relate to such committee, unless the context
otherwise requires. For the purposes of the Plan, a director or member of such
committee shall be deemed to be "disinterested" only if such person qualified as
a "disinterested person" within the meaning of paragraph (c)(2) of Rule 16b-3
promulgated under the Securities Exchange Act of 1934, as amended (the "Exchange
Act"), as such term is interpreted from time to time.

           4.       Type of Options.

           Options granted pursuant to the Plan shall be authorized by action of
the Board and may be designated as either incentive stock options meeting the
requirements of Section 422 of the Internal Revenue Code of 1986, as amended
(the "Code"), or non-qualified options which are not intended to meet the
requirements of such Section 422 of the Code, the designation to be in the sole
discretion of the Board. Options designated as incentive stock options that fail
to continue to meet the requirements of Section 422 of the Code shall be
redesignated as non-qualified options automatically without further action by
the Board on the date of such failure to continue to meet the requirements of
Section 422 of the Code.

           5.       Eligibility.

           Options designated as incentive stock options may be granted only to
officers and key employees of the Company or of any subsidiary corporation
(herein called "subsidiary" or "subsidiaries"), as defined in Section 424(f) of
the Code and the Income Tax Regulations (the "Regulations") promulgated
thereunder. Directors who are not otherwise employees of the Company or a
subsidiary shall not be eligible to be granted incentive stock options pursuant
to the Plan. Options designated as non-qualified options may be granted to (i)
officers and key employees of the Company or of any of its subsidiaries, or (ii)
agents, directors of and consultants to the Company, whether or not otherwise
employees of the Company.

           In determining the eligibility of an individual to be granted an
Option, as well as in determining the number of shares to be subject to any such
Option, the Board shall take into account the position and responsibilities of
the individual being considered, the nature and value to the Company or its
subsidiaries of his or her service and accomplishments, his or her present and
potential contribution to the success of the Company or its subsidiaries, and
such other factors as the Board may deem relevant.

           6.       Restrictions on Incentive Stock Options.

           Incentive stock options (but not non-qualified options) granted under
the Plan shall be subject to the following restrictions:


                                       -2-

<PAGE>
<PAGE>



           (a) Limitation on Number of Shares. Ordinarily, the aggregate fair
           market value of the shares of Common Stock with respect to which
           incentive stock options are granted (determined as of the date the
           incentive stock options are granted), exercisable for the first time
           by an individual during any calendar year shall not exceed $100,000.
           If an incentive stock option is granted pursuant to which the
           aggregate fair market value of shares with respect to which it first
           becomes exercisable in any calendar year by an individual exceeds
           such $100,000 limitation, the portion of such option which is in
           excess of the $100,000 limitation shall be treated as a non-qualified
           option pursuant to Section 422(d)(1) of the Code. In the event that
           an individual is eligible to participate in any other stock option
           plan of the Company or any subsidiary of the Company which is also
           intended to comply with the provisions of Section 422 of the Code,
           such $100,000 limitation shall apply to the aggregate number of
           shares for which incentive stock options may be granted under the
           Plan and all such other plans.

           (b) Ten Percent (10%) Shareholder. If any employee to whom an
           incentive stock option is granted pursuant to the provisions of the
           Plan is on the date of grant the owner of stock (as determined under
           Section 424(d) of the Code) possessing more than ten percent (10%) of
           the total combined voting power of all classes of stock of the
           Company or any subsidiary of the Company, then the following special
           provisions shall be applicable to the incentive stock options granted
           to such individual:

                    (i)      The Option price per share subject to such
                             incentive stock options shall be not less than 110%
                             of the fair market value of the stock determined at
                             the time such Option was granted. In determining
                             the fair market value under this clause (i), the
                             provisions of Section 8 hereof shall apply.

                    (ii)     The incentive stock option by its terms shall not
                             be exercisable after the expiration of five (5)
                             years from the date such Option is granted.

           7.       Option Agreements.

           Each Option shall be evidenced by an agreement (the "Agreement") duly
executed on behalf of the Company and by the grantee to whom such Option is
granted, which Agreement shall comply with and be subject to the terms and
conditions of the Plan. The Agreement may contain such other terms, provisions
and conditions which are not inconsistent with the Plan as may be determined by
the Board; provided that Options designated as incentive stock options shall
meet all of the conditions for incentive stock options as defined in Section 422
of the Code. No Option shall be granted within the meaning of the Plan and no
purported grant of any Option shall be effective until the Agreement shall have
been duly executed on behalf of the Company and the grantee. More than one
Option may be granted to an individual, subject, if applicable, to the
limitations of Section 6 hereof.

           8.       Option Price.

           (a) Subject to the conditions set forth in Section 8(d) hereof, the
option price or prices of shares of the Common Stock for Options designated as
non-qualified stock options shall be as determined by the Board; provided,
however, that such option price shall be not less than the fair market value of
the shares subject to such Option, determined as of the date of grant of such
Option.

           (b) Subject to the conditions set forth in Sections 6(b) and 8(d)
hereof, the option price or prices of shares of the Company's Common Stock for
incentive stock options shall be at least the fair market value of such Common
Stock at the time the Option is granted as determined by the Board in accordance
with the Regulations promulgated under Section 422 of the Code.

           (c) If such shares are then listed on any national securities
exchange, the fair market value shall be the mean between the high and low sales
prices, if any, on the largest such exchange on the date of the grant of the
Option or, if none, shall be determined by taking a weighted average of the
means between the highest and lowest sales prices on the nearest date before and
the nearest date after the date of grant in accordance with Section 25.2512-2 of
the Regulations. If the shares are not then listed on any such exchange, the
fair market value of such shares shall be the mean between the closing "Bid" and
the closing "Ask" prices, if any, as reported in the National Association of
Securities Dealers Automated Quotation System ("NASDAQ") for the date of the
grant of the Option, or, if none, shall be determined by taking a weighted
average of the means between the highest and lowest sales prices on the nearest
date before and the nearest date after the date of grant in accordance with
Section 25.2512-2 of the Regulations. If the shares are not then either listed
on any such exchange or quoted in NASDAQ, the fair market value shall be the
mean between the average of the "Bid" and "Ask" prices on the National Daily
Quotation Service for the date of the grant of the Option, or, if none, shall be
determined by taking a weighted average of the means between the highest and
lowest sales prices on the nearest date before and the nearest date after the
date of grant in accordance with Section 25.2512-2 of the Regulations. If the
fair market value cannot be determined under the preceding three sentences, it
shall be determined in good faith by the Board.

           (d) Prior to the effective date of the Company's contemplated initial
public offering, any options granted by the Company must be granted at an
exercise price per share of not less than the per share initial public offering
price of the Common Stock.

           9.       Manner of Payment; Manner of Exercise.

           (a) Options granted under the Plan may provide for the payment of the
option price by delivery of (i) cash or a check payable to the order of the
Company in an amount equal to the option price of such Options, (ii) shares of
Common Stock owned by the grantee having a fair market value equal in amount to
the option price of the Options being

                                       -4-

<PAGE>
<PAGE>



exercised, or (iii) any combination of (i) and (ii); provided, however, that
payment of the option price by delivery of shares of Common Stock owned by such
grantee may be made only upon the condition that such payment does not result in
a charge to earnings for financial accounting purposes as determined by the
Board, unless such condition is waived by the Board. The fair market value of
any shares of Common Stock which may be delivered as payment upon exercise of an
Option shall be determined by the Board in accordance with Section 8 hereof.

           (b) To the extent that the right to purchase shares under an Option
has accrued and is in effect, Options may be exercised in full at one time or in
part from time to time, by giving written notice, signed by the person or
persons exercising the Option, to the Company, stating the number of shares with
respect to which the Option is being exercised, accompanied by payment in full
for such shares as provided in Section 9(a) hereof. Upon such exercise, delivery
of a certificate for paid-up non-assessable shares shall be made at the
principal office of the Company to the person or persons exercising the Option
at such time, during ordinary business hours, after thirty (30) days but not
more than ninety (90) days from the date of receipt of the notice by the
Company, as shall be designated in such notice, or at such time, place and
manner as may be agreed upon by the Company and the person or persons exercising
the Option.

           10.      Exercise of Options.

           Each Option granted under the Plan shall, subject to Section 11(b)
and Section 14 hereof, be exercisable at such time or times and during such
period as shall be set forth in the Agreement; provided, however, that no Option
granted under the Plan shall have a term in excess of ten (10) years from the
date of grant. To the extent that an Option is not exercised by a grantee when
it becomes initially exercisable, it shall not expire but shall be carried
forward and shall be exercisable, on a cumulative basis, until the expiration of
the exercise period. No partial exercise may be made for less than one hundred
(100) full shares of Common Stock.

           11.      Term of Options; Exercisability.

           (a)      Term.

                    (i)         Each Option shall expire on a date determined by
                                the Board which is not more than ten (10) years
                                from the date of the granting thereof, except
                                (a) as otherwise provided pursuant to the
                                provisions of Section 6(b) hereof, and (b) for
                                earlier termination as herein provided.

                    (ii)        Except as otherwise provided in this Section 11,
                                an Option granted to any grantee whose
                                employment, by the Company or any of its
                                subsidiaries, is terminated, shall terminate on
                                the earlier of

<PAGE>



                                (i) ninety (90) days after the date such
                                grantee's employment, for the Company or any
                                such subsidiary, is terminated, or (ii) the date
                                on which the Option expires by its terms.

                    (iii)        If the employment of a grantee is terminated by
                                 the Company or any of its subsidiaries for
                                 cause or because the grantee is in breach of
                                 any employment agreement or because the grantee
                                 voluntarily terminates such employment, such
                                 Option will terminate on the date the grantee's
                                 employment is terminated by the Company or any
                                 such subsidiary, unless the Board determines,
                                 at the time of such option, to extend such
                                 option for a specified period (but not beyond
                                 the period described in Section 11(a)(ii)).

                    (iv)        If the employment of a grantee is terminated by
                                the Company or any of its subsidiaries because
                                the grantee has become permanently disabled
                                (within the meaning of Section 22(e)(3) of the
                                Code), such Option shall terminate on the
                                earlier of (i) one (1) year after the date such
                                grantee's employment, by the Company or any such
                                subsidiary, is terminated, or (ii) the date on
                                which the Option expires by its terms.

                    (v)         In the event of the death of any grantee, any
                                Option granted to such grantee shall terminate
                                one (1) year after the date of death, or on the
                                date on which the Option expires by its terms,
                                whichever occurs first.

           (b)      Exercisability.

                    (i)         An Option granted to a grantee whose employment,
                                by the Company or any of its subsidiaries, is
                                terminated, for whatever reason, including,
                                without limitation, death or disability, shall
                                be exercisable only to the extent that such
                                Option has accrued and is in effect on the date
                                such grantee's employment, by the Company or any
                                such subsidiary, is terminated.


           12.      Options Not Transferable.

           The right of any grantee to exercise any Option granted to him or
her shall not be assignable or transferable by such grantee other than by will
or the laws of descent and distribution, or the rules thereunder, and any such
Option shall be exercisable during the lifetime of such grantee only by him
or her. Any Option granted under the Plan shall be null and void and without
effect upon the bankruptcy of the grantee to whom the Option is granted, or
upon any attempted assignment or transfer, except as herein provided, including
without limitation, any purported assignment, whether voluntary or by operation
of law, pledge, hypothecation or other disposition, attachment, trustee process
or similar process, whether legal or equitable, upon such Option.

           13.      Recapitalization, Reorganizations and the Like.

           In the event that the outstanding shares of the Common Stock are
changed into or exchanged for a different number or kind of shares or other
securities of the Company or of another corporation by reason of any
reorganization, merger, consolidation, recapitalization, reclassification, stock
split-up, combination of shares, or dividends payable in capital stock,
appropriate adjustment shall be made in the number and kind of shares as to
which Options may be granted under the Plan and as to which outstanding
Options, or portions thereof then unexercised, shall be exercisable, to the
end that the proportionate interest of the grantee shall be maintained as before
the occurrence of such event; such adjustment in outstanding Options shall
be made without change in the total price applicable to the unexercised portion
of such Options and with a corresponding adjustment in the option price
per share.

           In addition, unless otherwise determined by the Board in its sole
discretion, in the case of any (i) sale or conveyance to another entity of all
or substantially all of the property and assets of the Company or (ii) Change in
Control (as hereinafter defined) of the Company, the purchaser(s) of the
Company's assets or stock, in his, her or its sole discretion, may deliver to
the grantee the same kind of consideration that is delivered to the shareholders
of the Company as a result of such sale, conveyance or Change in Control, or the
Board may cancel all outstanding Options in exchange for consideration in cash
or in kind, which consideration in both cases shall be equal in value to the
value of those shares of stock or

                                       -7-

<PAGE>
<PAGE>



other securities the grantee would have received had the Option been exercised
(but only to the extent then exercisable) and had no disposition of the shares
acquired upon such exercise been made prior to such sale, conveyance or Change
in Control, less the option price therefor. Upon receipt of such consideration,
all Options (whether or not then exercisable) shall immediately terminate and be
of no further force or effect. The value of the stock or other securities the
grantee would have received if the Option had been exercised shall be determined
in good faith by the Board, and in the case of shares of Common Stock, in
accordance with the provisions of Section 8 hereof.

           The Board shall also have the power and right to accelerate the
exercisability of any Option, notwithstanding any limitations in this Plan or in
the Agreement upon such a sale, conveyance or Change in Control. Upon such
acceleration, any Option or portion thereof originally designated as an
incentive stock option that no longer qualifies as an incentive stock option
under Section 422 of the Code as a result of such acceleration shall be
redesignated as a non-qualified stock option without the necessity of further
Board action.

           A "Change in Control" shall be deemed to have occurred if any person,
or any two (2) or more persons acting as a group, and all affiliates of such
person or persons, who prior to such time owned less than fifty percent (50%) of
the then outstanding Common Stock, shall acquire such additional shares of
Common Stock in one (1) or more transactions, or series of transactions, such
that following such transaction or transactions, such person or group and
affiliates beneficially own fifty percent (50%) or more of the Common Stock
outstanding.

           Upon dissolution or liquidation of the Company, all Options
granted under this Plan shall terminate, but each grantee (if at such time in
the employ of or otherwise associated with the Company or any of its
subsidiaries as a director, agent or consultant) shall have the right,
immediately prior to such dissolution or liquidation, to exercise his or her
Option or to the extent then exercisable.

           If by reason of a corporate merger, consolidation, acquisition of
property or stock, separation, reorganization, or liquidation, the Board shall
authorize the issuance or assumption of a stock option or stock options in a
transaction to which Section 424(a) of the Code applies, then, notwithstanding
any other provision of the Plan, the Board may grant an option or options upon
such terms and conditions as it may deem appropriate for the purpose of
assumption of the old Option, or substitution of a new option for the old
Option, in conformity with the provisions of such Section 424(a) of the Code and
the Regulations thereunder, and any such option grant shall not reduce the
number of shares otherwise available for issuance under the Plan.

           No fraction of a share shall be purchasable or deliverable upon the
exercise of any Option, but in the event any adjustment hereunder in the number
of shares covered by the Option shall cause such number to include a fraction of
a share, such fraction shall be adjusted to the nearest smaller whole number of
shares.

           14.      No Special Employment Rights.

           Nothing contained in the Plan or in any Option granted under the
Plan shall confer upon any grantee any right with respect to the continuation of
his or her employment by the Company or any subsidiary or interfere in any way
with the right of the Company or any subsidiary, subject to the terms of any
separate employment agreement to the contrary, at any time to terminate such
employment or to increase or decrease the compensation of the Option holder
from the rate in existence at the time of the grant of an Option. Whether an
authorized leave of absence, or absence in military or government service, shall
constitute termination of employment shall be determined by the Board at the
time of such occurrence pursuant to uniform nondiscriminatory criteria.

           15.      Withholding.

           The Company's obligation to deliver shares upon the exercise of any
non-qualified Option granted under the Plan, or cash upon the exercise of an
Option granted under the Plan, shall be subject to the grantee's satisfaction
of all applicable Federal, state and local income and employment tax withholding
requirements. The Company and grantee may agree to withhold shares of Common
Stock purchased upon exercise of an Option to satisfy the above-mentioned
withholding requirements; provided, however, that no such agreement may be made
by a grantee who is an "officer" or "director" within the meaning of Section 16
of the Exchange Act, except pursuant to a standing election to so withhold
shares of Common Stock purchased upon exercise of an Option, such election to be
made not less than six (6) months prior to such exercise and which election may
be revoked only upon six (6) months prior written notice.

           16.      Restrictions on Issuance of Shares.

           (a) Notwithstanding the provisions of Section 9 hereof, the Company
may delay the issuance of shares covered by the exercise of an Option and the
delivery of a certificate for such shares until one of the following conditions
shall be satisfied:

                    (i)         The shares with respect to which such Option has
                                been exercised are at the time of the issue of
                                such shares effectively registered or qualified
                                under applicable Federal and state securities
                                acts now in force or as hereafter amended; or

                    (ii)        Counsel for the Company shall have given an
                                opinion, which opinion shall not be unreasonably
                                conditioned or withheld, that such shares are
                                exempt from registration and qualification under
                                applicable Federal and state securities acts now
                                in force or as hereafter amended.

           (b) It is intended that all exercises of Options shall be effective,
and the Company shall use its reasonable efforts to bring about compliance with
the above conditions within a reasonable time, except that the Company shall be
under no obligation to qualify shares or to cause a registration statement or a
post-effective amendment to any registration statement to be prepared for the
purpose of covering the issue of shares in respect of which any Option may be
exercised, except as otherwise agreed to by the Company in writing in its sole
discretion.

          17. Purchase for Investment; Rights of Holder on Subsequent
Registration.

          Unless and until the shares to be issued upon exercise of an Option
granted under the Plan have been effectively registered under the Securities Act
of 1933, as amended ("1933 Act"), as now in force or hereafter amended, the
Company shall be under no obligation to issue any shares covered by any Option
or unless the person who exercises such Option, in whole or in part, shall
give a written representation and undertaking to the Company which is
satisfactory in form and scope to counsel for the Company and upon which, in the
opinion of such counsel, the Company may reasonably rely, that he or she is
acquiring the shares issued pursuant to such exercise of the Option for his
or her own account as an investment and not with a view to, or for sale in
connection with, the distribution of any such shares, and that he or she will
make no transfer of the same except in compliance with any rules and regulations
in force at the time of such transfer under the 1933 Act, or any other
applicable law, and that if shares are issued without such registration, a
legend to this effect may be endorsed upon the securities so issued.

          In the event that the Company shall, nevertheless, deem it necessary
or desirable to register under the 1933 Act or other applicable statutes any
shares with respect to which an Option shall have been exercised, or to qualify
any such shares for exemption from the 1933 Act or other applicable statutes,
then the Company may take such action and may require from each grantee such
information in writing for use in any registration statement, supplementary
registration statement, prospectus, preliminary prospectus or offering circular
as is reasonably necessary for such purpose and may require reasonable indemnity
to the Company and its officers and directors from such holder against all
losses, claims, damages and liabilities arising from such use of the information
so furnished and caused by any untrue statement of any material fact therein or
caused by the omission to state a material fact required to be stated therein or
necessary to make the statements therein not misleading in the light of the
circumstances under which they were made.

          18. Loans.

          At the discretion of the Board, the Company may loan to the grantee
some or all of the option price of the shares acquired upon exercise of an
Option.

          19. Modification of Outstanding Options.


                                      -10-

          Subject to any applicable limitations contained herein, the Board may
authorize the amendment of any outstanding Option with the consent of the
grantee when and subject to such conditions as are deemed to be in the best
interests of the Company and in accordance with the purposes of the Plan.

          20. Approval of Stockholders.

          The Plan shall become effective upon adoption by the Board; provided,
however, that the Plan shall be submitted for approval by the stockholders of
the Company no later than twelve (12) months after the date of adoption of the
Plan by the Board. Should the stockholders of the Company fail to approve the
Plan within such twelve-month period, all Options granted thereunder shall be
and become null and void.

           21.      Termination and Amendment of Plan.

           Unless sooner terminated as herein provided, the Plan shall terminate
ten (10) years from the date upon which the Plan was duly adopted by the Board.
The Board may at any time terminate the Plan or make such modification or
amendment thereof as it deems advisable; provided, however, that (i) the Board
may not, without the approval of the stockholders of the Company obtained in the
manner stated in Section 21 hereof, increase the maximum number of shares for
which Options may be granted or change the designation of the class of
persons eligible to receive Options under the Plan, and (ii) any such
modification or amendment of the Plan shall be approved by a majority of the
stockholders of the Company to the extent that such stockholder approval is
necessary to comply with applicable provisions of the Code, rules promulgated
pursuant to Section 16 of the Exchange Act (if applicable), applicable state
law, or applicable NASD or exchange listing requirements. Termination or any
modification or amendment of the Plan shall not, without the consent of a
grantee, affect his or her rights under an Option theretofore granted to him
or her.

           22.      Limitation of Rights in the Option Shares.

           A grantee shall not be deemed for any purpose to be a stockholder of
the Company with respect to any of the Options except to the extent that the
Option shall have been exercised with respect thereto and, in addition, a
certificate shall have been issued theretofore and delivered to the grantee.

           23.      Notices.

           Any communication or notice required or permitted to be given under
the Plan shall be in writing, and mailed by registered or certified mail or
delivered by hand, if to the Company, to the attention of the Chief Executive
Officer at the Company's principal place of business; and, if to a grantee, to
his or her address as it appears on the records of the Company.

                          UNDER 1996 STOCK OPTION PLAN
                           NON-QUALIFIED STOCK OPTION

                                      __, 1996



         AGREEMENT entered into by and between Bigmar, Inc., a Delaware
corporation with its place of business at ________________________, and the
undersigned officer and director of the Company (the "Optionee").

         1. The Company desires to grant the Optionee a non-qualified stock
option under the Company's 1996 Stock Option Plan (the "Plan") to acquire shares
of the Company's Common Stock, $.001 par value per share (the "Shares").

           2. The Plan provides that each option is to be evidenced by an option
agreement, setting forth the terms and conditions of the option.

          ACCORDINGLY, in consideration of the premises and of the mutual
covenants and agreements contained herein, the Company and the Optionee hereby
agree as follows:

           1. Grant of Option.

           The Company hereby grants to the Optionee a non-qualified stock
option (the "Option") to purchase all or any part of an aggregate of the number
of Shares shown at the end of this Agreement on the terms and conditions
hereinafter set forth. This option shall not be treated as an incentive stock
option under Section 422 of the Internal Revenue Code of 1986, as amended (the
"Code").

           2. Purchase Price.

           The purchase price ("Purchase Price") for the Shares covered by the
Option shall be $___ per Share.

           3. Time of Exercise of Option.

           The Option shall vest in [five] equal installments of ______ shares
each, the first commencing upon the consummation of the Company's initial public
offering of the Company's securities pursuant to a certain Registration
Statement on Form S-1, file No. 333-3830 (the "Offering") and the second, third,
[fourth and fifth] commencing on the first, second [third and fourth]
anniversary dates of the Offering. To the extent the Option is not exercised by
the Optionee when it becomes exercisable, it shall not expire, but shall be
carried forward and shall be exercisable for a period of

five (5) years following the date of vesting, provided, however, that no partial
exercise of an Option shall be for less than one hundred (100) full Shares.

           4. Term of Option; Exercisability.

           (a) Term of Option.

                    (i)       Each Option shall expire five (5) years from the
                              date of vesting, except (a) as otherwise provided
                              pursuant to the provisions of Section 11(d)(i),
                              and (b) for earlier termination as herein
                              provided.

                    (ii)      Except as otherwise provided in this Section 4,
                              an Option granted to any grantee whose employ-
                              ment, by the Company or any of its subsidiaries,
                              is terminated, shall terminate on the earlier of
                              (i) ninety (90) days after the date such
                              grantee's employment, for the Company or any such
                              subsidiary, is terminated, or (ii) the date on
                              which the Option expires by its terms.

                    (iii)     If the employment of a grantee is terminated by
                              the Company or any of its subsidiaries for cause
                              or because the grantee is in breach of any
                              employment agreement or because the grantee vol-
                              untarily terminates such employment, such Option
                              will terminate on the date the grantee's employ-
                              ment is terminated by the Company or any such
                              subsidiary, unless the Board determines, at the
                              time of such option, to extend such option for a
                              specified period (but not beyond the period
                              described in Section 4(a)(ii)).

                    (iv)      If the employment of a grantee is terminated by
                              the Company or any of its subsidiaries because
                              the grantee has become permanently disabled
                              (within the meaning of Section 22(e)(3) of the
                              Code), such Option shall terminate on the earlier
                              of (i) one (1) year after the date such grantee's
                              employment, by the Company or any such subsid-
                              iary, is terminated, or (ii) the date on which
                              the Option expires by its terms.

                    (v)       In the event of the death of any grantee, any
                              Option granted to such grantee shall terminate one
                              (1) year after the date of death, or on the date
                              on which the Option expires by its terms,
                              whichever occurs first.

           (b) Exercisability.

                    (vi)      An Option granted to a grantee whose employment,
                              by the Company or any of its subsidiaries, is
                              terminated, for whatever reason, including, with-
                              out limitation, death or disability, shall be
                              exercisable only to the extent that such Option
                              has accrued and is in effect on the date such
                              grantee's employment, by the Company or any such
                              subsidiary, is terminated.



           5. Manner of Exercise of Option.

           (a) To the extent that the right to purchase shares under an Option
has accrued and is in effect, Options may be exercised in full at one time or in
part from time to time, by giving written notice, signed by the person or
persons exercising the Option, to the Company, stating the number of shares with
respect to which the Option is being exercised, accompanied by payment in full
for such shares as provided in Section 9(a) of the Plan. Upon such exercise,
delivery of a certificate for paid-up non-assessable shares shall be made at the
principal office of the Company to the person or persons exercising the Option
at such time, during ordinary business hours, after thirty (30) days but not
more than ninety (90) days from the date of receipt of the notice by the
Company, as shall be designated in such notice, or at such time, place and
manner as may be agreed upon by the Company and the person or persons exercising
the Option unless otherwise required by Section 17 of the Plan.

           (b) The Company shall at all times during the term of the Option
reserve and keep available such number of Shares as will be sufficient to
satisfy the requirements of the Option.

           6. Non-Transferability.

           The right of any Optionee to exercise any Option granted to him or
her shall not be assignable or transferable by such grantee other than by will
or the laws of descent and distribution, or the rules thereunder, and any such
Option shall be exercisable during the lifetime of such grantee only by him or
her. Any Option granted under the Plan shall be null and void and without effect
upon the bankruptcy of the grantee to whom the Option is granted, or upon any
attempted assignment or transfer, except as herein provided, including without
limitation, any purported assignment, whether voluntary or by operation of law,
pledge, hypothecation or other disposition, attachment, trustee process or
similar process, whether legal or equitable, upon such Option.

           7. Representation Letter and Investment Legend.

           (a) In the event that for any reason the Shares to be issued upon
exercise of the Option shall not be effectively registered under the Securities

           9. No Special Employment Rights.

deemed by any person under any circumstances to bind the Company to continue the
employment of the Optionee for the period within which this Option may be
exercised. However, during the period of the Optionee's employment, the Optionee
shall render diligently and faithfully the services which are assigned to the
Optionee from time to time by the Board or by the executive officers of the

                                    EXHIBIT 1
                            TO STOCK OPTION AGREEMENT


Gentlemen:

           In connection with the exercise by me as to _____ shares of Common
Stock, no par value per share, of Bigmar, Inc. (the "Company"), under the
non-qualified stock option agreement dated ______ __, 1996, granted to me under
the 1996 Stock Option Plan, I hereby acknowledge that I have been informed
as follows:

           1. The shares of common stock of the Company to be issued to me
pursuant to the exercise of said option have not been registered under the
Securities Act of 1933, as amended (the "1933 Act"), and accordingly, must be
held indefinitely unless such shares are subsequently registered under the 1933
Act, or an exemption from such registration is available.

           2. Routine sales of securities made in reliance upon Rule 144 under
the 1933 Act can be made only after the holding period and in limited amounts in
accordance with the terms and conditions provided by that Rule, and in any sale
to which that Rule is not applicable, registration or compliance with some other
exemption under the 1933 Act will be required.

           3.       The Company is under no obligation to me to register the
shares or to comply with any such exemptions under the 1933 Act.

           4. The availability of Rule 144 is dependent upon adequate current
public information with respect to the Company being available and, at the time
that I may desire to make a sale pursuant to the Rule, the Company may neither
wish nor be able to comply with such requirement.

           In consideration of the issuance of certificates for the shares to
me, I hereby represent and warrant that I am acquiring such shares for my own
account for investment, and that I will not sell, pledge or transfer such shares
in the absence of an effective registration statement covering the same, except
as permitted by the provisions of Rule 144, if applicable, or some other
applicable exemption under the 1933 Act. In view of this representation and
warranty, I agree that there may be affixed to the certificates for the shares
to be issued to me, and to all certificates issued hereafter representing such
shares (until in the opinion of counsel, which opinion must be reasonably
satisfactory in form and substance to counsel for the Company, it is no longer
necessary or required) a legend as follows:

                    "The shares of common stock represented by this certificate
                    have not been registered under the Securities Act of 1933,
                    as amended (the "Act"), and were acquired by the registered
                    holder, pursuant to a representation and warranty that such
                    holder was acquiring such shares for his own account and for
                    investment, with no intention to transfer or dispose of the
                    same, in violation of the registration requirements of the
                    Act. These shares may not be sold, pledged, or transferred
                    in the absence of


<PAGE>
<PAGE>



                    an effective registration statement under the Act, or an
                    opinion of counsel, which opinion is reasonably satisfactory
                    to counsel to the Company, to the effect that registration
                    is not required under the Act."


           I further agree that the Company may place a stop order with its
Transfer Agent, prohibiting the transfer of such shares, so long as the legend
remains on the certificates representing the shares.


                                                  Very truly yours,

Gentlemen:

           The undersigned Optionee hereby elects and agrees that, whenever the
undersigned exercises a stock option (including any options which now or may
hereafter be granted), the Company shall withhold from the shares issuable upon
such exercise, such number of shares as is equal in value to the federal and
state withholding taxes due upon such exercise. The undersigned further
acknowledges and agrees that this election may not be revoked without six (6)
months prior written notice to the Company.

(the "Option") to purchase all or any part of an aggregate of the number of

stock option under Section 422 of the Internal Revenue Code of 1986, as amended

         4. Term of Option; Exercisability.

         (a) Term of Option.

                    (i)       Each Option shall expire five (5) years from the
                              date of vesting, except (a) as otherwise provided
                              pursuant to the provisions of Section 11(d)(i) of
                              the Plan, and (b) for earlier termination as

                              is terminated, shall terminate on the earlier of
                              (i) ninety (90) days after the date such
                              grantee's employment, for the Company or any
                              such subsidiary, is terminated, or (ii) the date

                              employment agreement or because the grantee
                              voluntarily terminates such employment, such
                              Option will terminate on the date the grantee's

                              (within the meaning of Section 22(e)(3) of the
                              Code), such Option shall terminate on the ear-

                    (v)       In the event of the death of any grantee, any

         (b) Exercisability.

                    (vi)      An Option granted to a grantee whose employment,
                              by the Company or any of its subsidiaries, is
                              terminated, for whatever reason, including,
                              without limitation, death or disability, shall
                              be exercisable only to the extent that such
                              Option has accrued and is in effect on the date

                              such subsidiary, is terminated.



         5. Manner of Exercise of Option.

         (a) To the extent that the right to purchase shares under an Option has
accrued and is in effect, Options may be exercised in full at one time or in
part from time to time, by giving written notice, signed by the person or
persons exercising the Option, to the Company, stating the number of shares with
respect to which the Option is being exercised, accompanied by payment in full
for such shares as provided in Section 9(a) of the Plan. Upon such exercise,
delivery of a certificate for paid-up non-assessable shares shall be made at the
principal office of the Company to the person or persons exercising the Option
at such time, during ordinary business hours, after thirty (30) days but not
more than ninety (90) days from the date of receipt of the notice by the
Company, as shall be designated in such notice, or at such time, place and
manner as may be agreed upon by the Company and the person or persons exercising
the Option unless otherwise required by Section 17 of the Plan.

         (b) The Company shall at all times during the term of the Option
reserve and keep available such number of Shares as will be sufficient to
satisfy the requirements of the Option.

         6. Non-Transferability.

         The right of any Optionee to exercise any Option granted to him or her
shall not be assignable or transferable by such grantee other than by will or
the laws of descent and distribution, or the rules thereunder, and any such
Option shall be exercisable during the lifetime of such grantee only by him or
her. Any Option granted under the Plan shall be null and void and without effect
upon the bankruptcy of the grantee to whom the Option is granted, or upon any
attempted assignment or transfer, except as herein provided, including without
limitation, any purported assignment, whether voluntary or by operation of law,
pledge, hypothecation or other disposition, attachment, trustee process or
similar process, whether legal or equitable, upon such Option.

Act of 1933, as amended (the "1933 Act"), upon any date on which the Option is
exercised in whole or in part, the person exercising the Option shall give a
written representation to the Company in the form attached hereto as Exhibit 1
and the Company shall place an "investment legend", so-called, as described in
Exhibit 1, upon any certificate for the Shares issued by reason of such
exercise.

         (b) The Company shall be under no obligation to qualify the Shares or
to cause a registration statement or a post-effective amendment to any
registration statement to be prepared for the purposes of covering the issue of
the Shares.

         8. Adjustments on Changes in Capitalization.

         Adjustments on changes in capitalization and the like shall be made in
accordance with the Plan, as in effect on the date of this Agreement.

         9. No Special Employment Rights.

         Nothing contained in the Plan or this Agreement shall be construed or
deemed by any person under any circumstances to bind the Company to continue the
employment of the Optionee for the period within which this Option may be
exercised. However, during the period of the Optionee's employment, the Optionee
shall render diligently and faithfully the services which are assigned to the
Optionee from time to time by the Board or by the executive officers of the
Company and shall at no time take any action which directly or indirectly would
be inconsistent with the best interests of the Company.

         10. Rights as a Stockholder.

         The Optionee shall have no rights as a stockholder with respect to any
Shares which may be purchased by exercise of this Option unless and until a
certificate or certificates representing such Shares are duly issued and
delivered to the Optionee.

         11. Withholding Taxes.

         Whenever Shares are to be issued upon exercise of this Option, the
Company shall have the right to require the Optionee to remit to the Company an
amount sufficient to satisfy all Federal, state and local withholding tax
requirements prior to the delivery of any certificate or certificates for such
Shares. The Company may agree to permit the Optionee to withhold Shares

by an Optionee who is an officer or director within the meaning of Section 16 of
the Securities Exchange Act of 1934, as amended, except pursuant to a standing
election to so withhold Shares purchased upon exercise of an Option, such
election to be made in the form set forth in Exhibit 2 hereto and to be made not
less than six (6) months prior to the date of such exercise. Such election may
be revoked by the Optionee only upon six (6) months prior written notice to the
Company.

         IN WITNESS WHEREOF, the Company has caused this Agreement to be
executed, and the Optionee has hereunto set his or her hand, all as of the day
and year first above written.

                            TO STOCK OPTION AGREEMENT


Gentlemen:

         In connection with the exercise by me as to       shares of Common
Stock, no par value per share (the "Common Stock" or the "shares"), of Bigmar,
Inc. (the "Company") under the incentive stock option agreement dated _____ __,
1996, granted to me under the 1996 Stock Option Plan, I hereby acknowledge that
I have been informed as follows:

         1. The Common Stock of the Company to be issued to me pursuant to the
exercise of said option have not been registered under the Securities Act of
1933, as amended (the "1933 Act"), and accordingly, must be held indefinitely
unless such shares are subsequently registered under the 1933 Act, or an
exemption from such registration is available.

         2. Routine sales of securities made in reliance upon Rule 144 under the
1933 Act can be made only after the holding period and in limited amounts in
accordance with the terms and conditions provided by that Rule, and in any sale
to which that Rule is not applicable, registration or compliance with some other
exemption under the 1933 Act will be required.

         3. The Company is under no obligation to me to register the shares or
to comply with any such exemptions under the 1933 Act.

         4. The availability of Rule 144 is dependent upon adequate current
public information with respect to the Company being available and, at the time
that I may desire to make a sale pursuant to the Rule, the Company may neither
wish nor be able to comply with such requirement.

         In consideration of the issuance of certificates for the shares to me,
I hereby represent and warrant that I am acquiring such shares for my own
account for investment, and that I will not sell, pledge or transfer such shares
in the absence of an effective registration statement covering the same, except
as permitted by the provisions of Rule 144, if applicable, or some other
applicable exemption under the 1933 Act. In view of this representation and
warranty, I agree that there may be affixed to the certificates for the shares
to be issued to me, and to all certificates issued hereafter representing such
shares (until in the opinion of counsel, which opinion must be reasonably
satisfactory in form and substance to counsel for the Company, it is no longer
necessary or required) a legend as follows:

                  "The shares of common stock represented by this certificate
                  have not been registered under the Securities Act of 1933, as
                  amended (the "Act"), and were acquired by the registered
                  holder, pursuant to a representation and warranty that such
                  holder was acquiring such shares for his own account and for
                  investment, with no intention


<PAGE>
<PAGE>



                  to transfer or dispose of the same, in violation of the
                  registration requirements of the Act. These shares may not be
                  sold, pledged, or transferred in the absence of an effective
                  registration statement under the Act, or an opinion of
                  counsel, which opinion is reasonably satisfactory to counsel
                  to the Company, to the effect that registration is not
                  required under the Act."


         I further agree that the Company may place a stop order with its
Transfer Agent, prohibiting the transfer of such shares, so long as the legend
remains on the certificates representing the shares.


                                                     Very truly yours,


                                       -2-

Gentlemen:

         The undersigned Optionee hereby elects and agrees that, whenever the
undersigned exercises a stock option (including any options which now or may
hereafter be granted), the Company shall withhold from the shares issuable upon
such exercise, such number of shares as is equal in value to the federal and
state withholding taxes due upon such exercise. The undersigned further
acknowledges and agrees that this election may not be revoked without six (6)
months prior written notice to the Company.
