                          BIGMAR, INC. AND SUBSIDIARIES

        NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS (UNAUDITED)

(1)      BASIS OF PRESENTATION

Bigmar, Inc. is a Delaware Corporation that owns 100% of two Swiss
Corporations, Bioren S.A. and Bigmar Pharmaceuticals S.A., and 100% of a
Delaware corporation, Bigmar Therapeutics, Inc.

In the opinion of management, the accompanying unaudited financial statements
include all adjustments necessary to present fairly the Company's financial
position at September 30, 1999 and December 31, 1998, and the results of
operations and the cash flows and comprehensive income for all periods
presented. Certain amounts in the accompanying financial statements have been
restated to conform to the September 30, 1999 presentation. The results of
operations for the three and nine months periods ended September 30, 1999 and
1998 are not necessarily indicative of the results to be expected for the
full fiscal year.

For a summary of significant accounting policies (which have not changed from
December 31, 1998) and additional financial information, see Bigmar, Inc.'s
Annual Report on Form 10-K for the year ended December 31, 1998. The 10-K
should be read in conjunction with these financial statements.

The consolidated financial statements include the accounts of the Company and
its subsidiaries, all of which are wholly owned. The three wholly-owned
subsidiaries are as follows : Bioren S.A. ("Bioren"), Bigmar Pharmaceuticals
S.A. ("Pharmaceuticals") and Bigmar Therapeutics Inc. ("Therapeutics"). All
significant intercompany accounts have been eliminated.

The financial statements of subsidiaries outside United States are stated
using the local currency as the functional currency. Assets and liabilities
of these companies are translated at the rates of exhange at the balance
sheet date. The resulting translation adjustments are included in accumulated
and other comprehensive income (loss). Income and expenses are translated at
average rates of exchange for the period.

The accompanying financial statements have been prepared assuming that the
Company will continue as a going concern. The construction of the Company's
pharmaceutical manufacturing plant in Barbengo, Switzerland and the process
of obtaining regulatory approvals has consumed a substantial amount of the
Company's resources. The manufacturing plant recently received regulatory
approval, from the United States Food and Drug Administration ("FDA") and the
Intercantonal Office for the Control of Medications ("IKS") in Switzerland,
to manufacture and sell certain injectible pharmaceutical products in the
U.S. and Switzerland. As a result, the Company anticipates that these
operations will begin to generate cash to help fund its expansion and further
planned research and development activities. During 1999, the Company has
received $2,888,995 in proceeds from the private placements of common stock.
The Company anticipates that additional capital funding together with cash
from operations will be required to sustain operations through March 2000.
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. Management is currently discussing additional financing with a number
of financial institutions and investors, but there are no assurances that the
Company will be able to obtain additional financing or that such financing,
if available, will be open on acceptable terms. No adjustments have been made
to reflect the recoverability or classification of recorded asset amounts or
the classification of liabilities should the Company be unable to continue as
a going concern.

                                       7

The Company has received its first order, valued at $1.0 million, under its
recently announced distribution and marketing relationship with American
Pharmaceutical Partners ("APP"). This initial order covers three of the
generic oncology drugs in varying dosages, Daunorubicin Hydrochloride,
Methotrexate and Leucovorin Calcium. First delivery is scheduled for the
fourth quarter of 1999. APP has also indicated its plans to order additional
generic oncology products from Bigmar which provide cost-effective therapies
used for remission in various types of cancer.

As of September 30, 1999, the Company had various notes, bonds, mortgages and
other borrowings totaling approximately $10.0 million, including $0.4 million
that is short term in nature. These monies were used to partially fund the
acquisition of Bioren, to acquire, construct, and equip the manufacturing
facility and to fund ongoing research and development and product
registration activities. During April 1999, the Company renegotiated two of
its debt agreements, whereby maturities of approximately $0.8 million were
extended to year 2000, and beyond.

(4)      COMMON STOCK ISSUED

In February 1999, the Company issued 236,666 shares of common stock to
accredited investors for prices ranging from $2.00 to $3.00 per share via
private placement offerings. Proceeds from the sale of shares totaled
$700,000 and were applied to working capital and general corporate purposes.

In March 1999, the Company issued 250,000 shares of common stock to
accredited investors for $3.00 per share via private placement offerings.
Proceeds from the sale of shares were applied to working capital and general

accredited investors for $3.00 per share via private placements, with the
proceeds applied to working capital and general corporate purposes.

(5)      RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

In June 1999, the Statement of Financial Accounting Standards No. 137 ("SFAS
No. 137"), "Accounting for Derivative Instruments and Hedging Activities -
Deferral of Effective Date of FASB Statement No. 133" was issued. This
Statement amended the effective date of the application of Statement of
Financial Accounting Standards No. 133 ("SFAS No. 133") "Accounting for
Derivative Instruments and Hedging Activities". The Company has analyzed the
impact of this Statement and does not expect this Statement to have a
material impact on the Company's financial position nor results of operations.

(6)      SEGMENT DATA

The Company manages its business segments primarily on a geographic basis
with each location representing a distinct segment. The Company's reportable
segments are comprised of Bioren, located in Couvet, Switzerland,
Pharmaceuticals, located in Barbengo, Switzerland, and the Company's
Corporate Headquarters, located in Johnstown, Ohio, U.S.A.

The Company evaluates the performance of its Bioren and Pharmaceuticals
segments based on segment profit / (loss). Segment profit / (loss) for these
segments includes sales and marketing, certain research and development, and
overhead charges directly attributable to the segment and excludes certain
expenses which are managed outside the reportable segments. Costs excluded
from these segments' profit primarily consist of corporate expenses, as well
as other research and development charges for testing of products targeted
for U.S. markets, and other general and administrative expenses which are
separately managed. The Company does not include intercompany transfers
between segments for management reporting purposes.

Summary information by segment for the nine months ended September 30, 1999
and 1998 is as follows:

                          BIGMAR, INC. AND SUBSIDIARIES

                MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                       CONDITION AND RESULTS OF OPERATIONS

Bigmar, Inc. (together with its subsidiaries, the "Company") is engaged in
manufacturing various pharmaceutical products in Europe and marketing them in
Europe and the United States. Its strategy is to supply world markets with a
full line of high quality, affordably priced, generic pharmaceutical
products, focusing on oncology products. The Company intends to manufacture,
in its state of the art facilities in Switzerland, off-patent generic
oncology drugs and additional oncology drugs as their patents expire. It will
then market these products through pharmaceutical company partners in Europe,
the United States and Canada. Bigmar currently has distribution rights to
more than 20 generic oncology products.

Bigmar, Inc. was incorporated in Delaware in September, 1995 and has three
wholly owned subsidiaries: Bigmar Pharmaceuticals SA - "Pharmaceuticals",
Bioren SA - "Bioren" and Bigmar Therapeutics, Inc.- "Therapeutics".
Pharmaceuticals and Bioren are both Swiss corporations and Therapeutics is a
Delaware corporation.

The Company manages its business segments primarily on a geographic basis
with each location representing a distinct segment.

THE COMPANY

The Company's corporate headquarters ("Corporate headquarters"), located in
Johnstown, Ohio, include a research and development laboratory used for the
testing of generic oncology and related products ("Oncology Products") to be
marketed in the United States.

The Company entered into a distribution and marketing arrangement with
American Pharmaceutical Partners ("APP") as the exclusive distributor of
certain Bigmar generic oncology products in North America and other selected
territories. The arrangement initially includes three of Bigmar's
market-ready generic oncology products along with several new products to be
identified in the future. On August 5, 1999, the Company received its initial
order, valued at $ 1.0 million, under this arrangement.

So far this year, the Company has received a total of seven Abbreviated New
Drug Application ("ANDA") approvals from the Food and Drug Administration for
the following products :

     -  Methotrexate for Injection USP, 1 g/vial (lyophilized)
     -  Methotrexate for Injection USP, 25 mg/ml Preserved (lyophilized)
     -  Methotrexate for Injection USP, 25 mg/ml Preservative-free
        (lyophilized)
     -  Leucovorin Calcium for Injection USP, 200 mg/vial (lyophilized)
     -  Leucovorin Calcium for Injection USP, 500 mg/vial (lyophilized)
     -  Fluorouracil Injection USP, 50 mg/ml
     -  Daunorubicin Hydrochloride for Injection USP, 20 mg/vial (lyophilized)

The Company recently signed a licensing and supply agreement with Graminex,
L.L.C. to develop a new prostatitis therapy, BGM-24, and plans to file an
Investigational New Drug Application with the FDA for this therapy. Cynthia
R. May, a director and officer of the Company, is currently President of
Graminex, L.L.C., a manufacturer and supplier of botanical raw materials
containing proprietary active pharmaceutical substances. Jericho II, L.L.C,
an investment entity controlled by Ms. May, is a principal shareholder of
Bigmar Inc.

BIOREN

Bioren is engaged in manufacturing and marketing various pharmaceutical
products in Switzerland. Current products include 18 types of intravenous
infusion solutions and other related products ("IV solutions"). Bioren's
strategy is to expand its current IV solutions product line and its market
penetration. Bioren's manufacturing facility (the "Bioren Facility") is
located in Couvet, Switzerland.

PHARMACEUTICALS

Pharmaceuticals manufactures and markets Oncology Products, such as
Leucovorin Calcium, Methotrexate, and Cisplatin. The Oncology Products are
currently marketed in Germany and Spain. Pharmaceuticals' primary strategy is
to supply world markets with a full range of high-quality, affordably priced
generic pharmaceutical products focusing on oncology. The products are
manufactured in its state-of-the-art facilities in Switzerland and marketed
through pharmaceutical company partners in Europe and shortly in the United
States. Pharmaceuticals has received regulatory approval to manufacture and
market certain Oncology Products from the United States Food and Drug
Administration ("FDA") and Switzerland's Intercantonal Office for the Control
of Medications ("IKS"). Pharmaceuticals' manufacturing facility (the "Bigmar
Facility") is located in Barbengo, Switzerland.

THERAPEUTICS

RESULTS OF OPERATIONS

Net sales, in the third quarter of 1999, decreased to $1.3 million from $2.0
million in the third quarter of 1998. Net sales, in the first nine months of
1999, decreased to $4.6 million from $4.9 million in the same period of 1998.
The decrease in net sales for the three months ended September 30, 1999 and
the nine month period ended September 30, 1999, is explained by the decrease
of sales in the oncological field generally and purchases by swiss hospitals
that were delayed to the fourth quarter 1999.

Cost of goods sold for the third quarter of 1999 was $1.0 million compared to
a cost of goods sold of $1.4 million for the third quarter of 1998. Cost of
goods sold, for the first nine months of 1999 was $3.4 million, compared to
$3.5 million for the same period of 1998. For both periods, the decrease was
attributable to the decrease in sales.


                                      12

<PAGE>

Gross margin decreased by $0.1 million to $0.4 million for the third quarter
1999, as compared to $0.5 million for the third quarter of 1998. As a
percentage of net sales, gross margin increased slightly to 27.5% from 26.7%
in 1998. The increase is due to cost efficiencies gained in the third
quarter. For the nine month period ended September 30, 1999, gross margin
amounted to $1.2 million as compared to $1.3 million for the same period of
1998. As a percentage of net sales, gross margin decreased from 27.0% in 1998
to 26.1% in 1999. The change in the gross margin for the year to date is
primarily a result of competitive pricing pressure in the European market and
the increased raw material costs.

Operating expenses increased by $270,000, or 16%, for the third quarter of
1999 as compared to the third quarter of 1998. The increase is due to
increased research and development. Operating expenses, however, decreased by
$360,000, or 7%, for the first nine months of 1999 as compared to the same
period in 1998. The decrease in operating expenses can be attributed to
efforts to minimize general and administrative costs in the current year,
which offset increased R & D spending.

Research and development costs increased to $1.0 million from $384,000 in the
third quarter of 1999 as compared to the same period in 1998. The increase is
due to new product development efforts. Research and development costs
increased to $2.2 million from $2.1 million for the nine months ended
September 30, 1999 as compared to the same period in 1998 due to new product
development as well as efforts to get the Company's facilities and
manufacturing processes ready for FDA inspections in 1999.

Selling, general and administrative expenses decreased from $1.3 million to
$904,000, or $377,000, from the third quarter of 1998 as compared to the
third quarter of 1999. Selling, general and administrative expenses decreased
from $3.2 million to $2.8 million, or $467,000, for the nine months ended
September 30, 1998 as compared to the same period in 1999. This change in
both periods is primarily due to a reduction in personnel as compared to 1998.

For the nine-month period ending September 30, 1999 as compared to the same
period of 1998, interest expense decreased by $170,000. Interest expense
decreased $37,000 during the third quarter of 1999 as compared to the third
quarter of 1998. The decreases are primarily due to a reduction of average
outstanding debt and a decrease of interest rates.

Foreign exchange losses amounted to $444,000 for the first nine months of
1999 as compared to the gain of $16,000 for the same period of 1998. For
the third quarter of 1999, the Company incurred a gain on foreign current
transactions of $242,000 compared to a gain of $811,000 during the third
quarter of 1999. The Company experiences fluctuations on foreign currency
based on the fluctuations of exchange rates. During the first six months of
1999, appreciation of the US Dollar against the Swiss Franc had a negative
impact on certain intercompany accounts receivable denominated in Swiss
Francs, resulting in the loss for the nine months ended September 30, 1999.
During the third quarter of 1999, the US Dollar depreciated slightly against
the Swiss Franc resulting in the foreign currency gain.

As a result of the foregoing, the Company's net loss for the third quarter
1999 amounted to approximately $1.6 million or $0.18 per share, compared to
$0.6 million or $0.14 per share for the third quarter of 1998. For the nine
months ended September 30, 1999, net loss amounted to $4.9 million or $0.57
per share versus $5.2 million or $1.23 per share during the first nine months
of 1998.

LIQUIDITY AND CAPITAL RESOURCES

As of September 30, 1999 and December 31, 1998, the Company had cash and cash
equivalents of $26,578 and $140,445, respectively.


                                      13

<PAGE>

The Company has incurred and will continue to incur substantial expenditures
for research and development activities related to bringing its products to
the commercial market. The Company intends to devote significant additional
funds to product development, formulation, clinical testing, product
registration, and other activities required for regulatory review of generic
oncological products. The amount required to complete such activities depends
upon the outcome of regulatory reviews. The regulatory bodies may require
more testing than is currently planned by the Company. There can be no
assurance that the FDA or any foreign government agency will approve the
Company's generic oncological products for sale or that these products will
achieve market success. Furthermore, the Company will need additional capital
to fund planned increases in production at Pharmaceuticals.

Inventory totaled approximately $2.9 million at September 30, 1999 and $1.6
million at December 31, 1998. The increase is primarily due to increased
production in anticipation of future orders.

Property, plant and equipment totaled approximately $15.4 million at
September 30, 1999 and $17.3 million at December 31, 1998. The decrease is
primarily due to depreciation and foreign currency fluctuations.

As of September 30, 1999, the Company had various notes, bonds, mortgages and
other borrowings totaling approximately $10.1 million, including $440,000
that is short term in nature. These monies were used to partially fund the
acquisition of Bioren, to acquire, construct, and equip the manufacturing
facility and to fund ongoing research and development and product
registration activities. During April 1999, the Company renegotiated two of
its debt agreements, whereby maturities of approximately $800,000 were
extended to year 2000, and beyond.

During the first nine months of 1999, pursuant to private placement
transactions with accredited investors, the Company raised $2,888,995 that
was applied to working capital and general corporate purposes.

The Company anticipates that additional capital funding together with cash
from operations will be required to sustain operations through March 2000.
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. Management is currently discussing additional financing with a number
of financial institutions and investors, but there are no assurances that the
Company will be able to obtain additional financing or that such financing,
if available, will be on acceptable terms.

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 equal 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 5% of share capital is not available for distribution to stockholders.

Changes in exchange rates between currencies may negatively impact the
Company's results of operations, specifically, net sales and gross profit
margins from international operations. In addition, the dollar-value
equivalent of anticipated cash flows could also be adversely affected. When
the Company determines that this risk has become significant, the Company may
attempt to manage that risk by using hedging techniques.

BANCA DEL GOTTARDO FINANCING

On October 26, 1999, the Company entered into a Note Purchase, Paying and
Conversion Agency Agreement (the "Note Agreement") with Banca del Gottardo, a
bank organized under the laws of Switzerland (the "Bank"). The closing of the
transaction under the Note Agreement occurred on October 29, 1999, with net
proceeds to be used to finance current operations of the Company.

Under the Note Agreement, the Company issued a global note in the principal
amount of approximately two million dollars ($2,000,000). Net proceeds of the
note transaction were $1,900,000, after paying the Bank a managing and
underwriting commission of five percent (5 %), calculated on the principal
amount, and out-of-pocket expenses of $6,700. The Note Agreement contemplates
that, from this global amount, the Bank will further sell 60 single notes in
denominations of $33,650 (the "Notes"). The term of the Notes is four (4)
years, and the interest rate on the Notes is four percent (4 %) per year,
payable semi-annually in arrear on April 29 and October 29 of each year until
maturity, commencing on April 29, 2000. Such interest is payable in Swiss
Francs. The Notes will be convertible, as early as March 1, 2000 up to the
close of business on October 22, 2003, into shares of common stock of the
Company. Under the Note Agreement and the terms of the Notes, the initial
conversion price is $3.75 of principal amount of the Notes for one share of
common stock of the Company (initially, 528,000 shares in the aggregate). The
conversion price is subject to adjustment based on events such as stock
splits and other specified events having an impact on the number of common
shares outstanding. The transaction was effected pursuant to Regulation S
("Reg S") promulgated by the United States Securities and Exchange
Commission under the Securities Act of 1933, as amended (the "Act"), and the
securities may not be transferred to a U.S. person, as defined in Reg S, for
a period of one year following closing. However, the Company has agreed and
expects prior to March, 2000, to effect a registration under the Act with
respect to resale of the conversion shares.

CITIZENS BANK'S LINE OF CREDIT

In November, 1999 the Company finalized arrangements with Citizens Bank of
Saginaw, Michigan for a $2 million revolving line of credit to be used
primarily to finance working capital needs in the United States, allowing the
Company to focus on growth opportunities from its line of generic oncology
drug products. Borrowings under the line of credit will bear interest at the
lender's prime rate, and are payable upon demand. The line of credit is (i)
guaranteed by affiliates of the Company, including John G. Tramontana,
Cynthia R. May, and members of her family.

YEAR 2000 ISSUE

Many computer systems currently record years in a two-digit format. Such
systems, if not modified, will be unable to recognize and properly process
information with dates beyond the year 1999. The potential

                                      15

<PAGE>

problems arising out of this inability are commonly referred to as the "Year
2000 Issue" or "Y2K" and will affect virtually all companies, government
agencies and other organizations to some degree.

INTERNAL SYSTEMS

The efficient operation of the Company's business is dependent in part on its
computer software programs and operating systems (collectively, "Programs and
Systems"). These Programs and Systems are used in several areas of the
Company's business, including research and development, purchasing, inventory
management, sales, shipping, and financial reporting, as well as in various
administrative functions. The Company has performed an assessment of its
computer systems to determine whether or not they were in compliance with
Year 2000 requirements. As of September 30, 1999, Bioren and Pharmaceuticals
Programs and Systems, including manufacturing and operations, were found to
be in compliance with such requirements. The Company's Headquarters Programs
and Systems include an accounting package and a document management system.
These Programs and Systems are also in compliance with Year 2000 requirements.

READINESS OF THIRD PARTIES

The Company is also working with its processing banks, network providers and
vendors to ensure their systems are Year 2000 compliant. All of these costs
will be borne by the processors, network and software companies and vendors.
Currently, the Company's processing banks and vendors are in the process of
completing their Year 2000 compliance programs. However, there can be no
assurance that the systems of other companies on which the Company relies
will be timely converted or that any such failure to convert by another
company would not have an adverse effect on the Company's Programs and
Systems.

RISKS ASSOCIATED WITH YEAR 2000

The Company is not aware, at this time, of any Year 2000 non-compliance that
will not be fixed by the Year 2000. However, some risks that the Company
faces include: the failure of internal information systems, defects in its
work environment, a slow down in its customers' ability to make payments, and
the availability of raw materials for manufacturing.

CONTINGENCY PLANS

The Company is in the process of developing contingency plans to address a
worst case Year 2000 scenario. This contingency plan is expected to be
completed by November 1999. Furthermore, no assurance can be given that any
or all of the Company's systems are or will be Year 2000 compliant, or that
the ultimate costs required to address the Year 2000 issue or the impact of
any failure to achieve substantial Year 2000 compliance will not have a
material adverse effect on the Company's financial condition.

                    QUANTITATIVE AND QUALITATIVE DISCLOSURES
                                ABOUT MARKET RISK


ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

In the normal course of business, operations of the Company are exposed to
fluctuations in currency values. These fluctuations can vary the costs of
financing, investing, and operating activities. The Company does not have any
programs in place to control these risks.

The Company's foreign currency risk exposure results from fluctuating
currency exchange rates, primarily the fluctuation of the U.S. dollar against
the Swiss franc ("SFr"). The Company faces transactional currency exposures
that arise when its foreign subsidiaries (or the Company itself) enter into
transactions, generally on an intercompany basis, denominated in currencies
other than their local currency. The Company also faces currency exposure
that arises from translating the results of its Swiss operations to the U.S.
dollar at exchange rates that have fluctuated from the beginning of the
period. The Company does not have any programs in place to control these
risks. However, historically the exchange rate between the U.S. dollar and
the Swiss franc has not fluctuated significantly.

The Company's exposure to market risk did not materially change from June 30,
1999.

PART II.  OTHER INFORMATION

ITEM 2(c). CHANGES IN SECURITIES - RECENT SALES OF UNREGISTERED SECURITIES

In April, 1999 the Company entered into a Consulting Contract with The Equity
Group, Inc. pursuant to which the Company is to receive financial public
relations and investor relations services. As part of the consideration for
such services, the Company issued to The Equity Group, Inc a warrant for
45,000 shares of common stock. The warrant is exercisable at any time through
April 15, 2004 at a price of $3.88 per share, and the Company has granted
"piggyback" registration rights with respect to the shares issuable upon
exercise.

In August 1999, in private placement transactions pursuant to Section 4(2)
and Rule 506, the Company issued 343,333 shares of common stock to accredited
investors, including a family member of Cynthia R. May, for $3.00 per share.

All of the share transactions summarized above were made directly by the
Company without use of an underwriter or placement agent and without payment
of commissions or other remuneration. Except as otherwise stated, in each
case the aggregate sales proceeds, after payment of offering expenses in
immaterial amounts, were applied to the working capital of the Company and
other general corporate purposes.

With respect to the exemption from registration claimed under Rule 506 and
Section 4(2) of the Securities Act of 1933, neither the Company nor any
person acting on its behalf offered or sold the securities by means of any
form of general solicitation or advertising. Prior to making any offer or
sale, the Company had reasonable grounds to believe and believed that each
prospective investor was capable of evaluating the merits and risks of the
investment and was able to bear the economic risk of the investment. Each
purchaser represented in writing that such purchaser was an accredited
investor and that the securities were being acquired for investment for such
purchaser's own account, and agreed that the securities would not be sold
without registration under the Securities Act or exemption therefrom. A
legend was placed on each certificate evidencing the securities stating that
the securities have not been registered under the Securities Act and setting
forth restrictions on their transferability.

ITEM 5. OTHER INFORMATION

In June, 1999 the Company entered into a letter of intent with American
Pharmaceuticals Partners, Inc. ("APP") pursuant to which APP is granted the
exclusive right to distribute certain of the Company's oncology drug products
in the United States and Canada. While definitive documentation of the
arrangement is expected to be finalized and executed shortly, the Company has
received initial orders valued at approximately $1 million, which products
are to be delivered in the fourth quarter. Additional orders for
approximately $4.0 million of Bigmar oncology products have subsequently been
scheduled.

              date upon which the Notes were first offered or the date of
              closing of this offering (the "Restricted Period"), it will not
              offer or sell, Notes to a person who is within the United States
              or to a United States person, (b) it has not delivered and will

              consent of the Company, (iii) represents and agrees with respect
              to each affiliate that acquires from it Notes for the purpose of

              within the meaning of Section 871 (h) (3) of the Code, (b) a bank
              on an extension of credit made pursuant to a loan agreement

              under section 864 (d) (4) of the Code, or (d) within a foreign
              country which the United States Secretary of the Treasury has
              determined under section 871 (h) (6) of the Code that the exchange
              of information with the foreign country is inadequate to prevent
              evasion of United States tax by United States persons, (v)
              represents and agrees that (a) on or before the delivery of the
              Permanent Global Note by the Company, Banca del Gottardo will

              made upon certification, in the form attached hereto as Annex K,
              that the beneficial owners of the Notes either (i) will not be
              United States persons or U.S. persons or (ii) are financial
              institutions (within the meaning of United States Treasury
              Regulation Section 1.165.12(c)(1)(v)) located outside the United
              States that are not United States persons and are purchasing such
              Notes for resale during the Restricted Period and certify they are
              not acquiring the Notes for purposes of resale directly to a
              United States person or to a person within the United States. Any
              certificates provided by a clearing organization must be based on
              statements provided to it by its members. Banca del Gottardo
              agrees to furnish to the Company a properly completed certificate
              with respect to each Note, in the form attached hereto as Annex K
              (and, in the case of clearing organizations, require statements of
              members of the clearing organization), on the earlier of the date

           of the Notes in due time with information and documentation for the
           preparation by Banca del Gottardo of the Information Memorandum (the
           "Information Memorandum") relating to the Issue, in compliance with
           Swiss law.

           The Information Memorandum shall be reviewed by the Company and Banca
           del Gottardo.

IX.        PRINTING OF THE NOTES

           The Notes and Coupons and all rights and obligations in connection
           therewith are documented solely in form of a Permanent Global Note as
           per Annex D hereto. Each Noteholder of a Note or Coupon therefore
           retains a co-ownership in the Permanent Global Note to the extent of
           his claim against the Company. Content and form of the Permanent
           Global Note must be in accordance with the regulations of SIS
           SEGAINTERSETTLE AG (the "SEGA"). Except as provided in item c) below,
           no printing and delivery of definitive Notes or Coupons will occur.

           a) Publicity: All documents and publications established in
              connection with the issue of the Notes (i.e. the Information
              Memorandum, advertisements, if any, as well as possible additional
              publications) must explicitly and prominently state that the Notes
              are represented by way of a Permanent Global Note and that
              investors are not entitled to receive definitive Notes or Coupons.

           b) Custodianship: Banca del Gottardo undertakes to hold in custody
              the Permanent Global Note, which it has received duly signed in
              accordance with Article VII item 3) above, after payment of the
              Net Proceeds to the Company. The Permanent Global Note remains in
              safekeeping with Banca del Gottardo during the entire duration of
              the issue and until the complete redemption of the Notes.


<PAGE>


           c) Arrangements for printing of the definitive Notes and Coupons: The
              Company irrevocably authorizes Banca del Gottardo to arrange for
              the printing of the definitive Notes with Coupons attached, in the
              name of and at the expense of the Company, should Banca del
              Gottardo deem such printing to be necessary or useful, or if the
              presentation of definitive Notes and Coupons is required by Swiss
              or foreign laws and regulations in connection with the enforcement
              of rights (e.g. in cases of bankruptcy, consolidation or
              reorganisation of the Issuer). In such case, the Notes and Coupons
              will be substantially in the form of Annex B and C. The Company
              irrevocably authorizes Banca del Gottardo to reproduce on the
              definitive Notes the signatures deposited with Banca del Gottardo
              in accordance with Article VII item 5) above.

              Should the definitive Notes and Coupons be printed, Banca del
              Gottardo will then exchange the Permanent Global Note against the
              definitive Notes and Coupons and thereupon cancel and return the
              Permanent Global Note to the Company.

           Notes and/or Coupons which are mutilated, lost or destroyed may be
           replaced by Banca del Gottardo in accordance with the respective
           provisions of the Terms of the Notes.

X.         SERVICING OF THE NOTES

           (1)    TRANSFER OF FUNDS

                  The Company will effect transfer of the funds in freely
                  disposable Swiss Francs required to make any payment of
                  principal or interest on the Notes, including the commissions
                  referred to in paragraph (2) hereafter, to Banca del Gottardo,
                  Lugano, as Paying Agent, for value the respective due date
                  provided that, if such due date does not fall on a Business
                  Day, the Company shall be obliged to effect transfer of such
                  payments for value the Business Day immediately preceding such
                  due date. Any transfer risk shall be borne by the Company.

                  "Business Day" means a day on which commercial banks are open
                  for domestic business and foreign exchange (including dealings
                  in Swiss Francs) in Lugano and New York.

                  Banca del Gottardo will supply the Company, by facsimile or
                  otherwise in writing received by the Company not less than
                  five Business Days prior to each due date for any payment
                  under the Notes, with any necessary information including
                  reference numbers and the name of a contact person for the
                  receipt of funds. Further in-


<PAGE>


                  formation regarding the transfer may be obtained by Banca del
                  Gottardo from the Company at the address set out in Article
                  XIV below.

                  Banca del Gottardo shall credit the funds received to separate
                  non-interest bearing accounts with Banca del Gottardo for each
                  Coupon due date and/or redemption date. The receipt by Banca
                  del Gottardo of the due and punctual payment of the funds in
                  Lugano shall release the Company of its obligations under the
                  Permanent Global Note or under the Notes for the interest and
                  principal, to the extent of such payment.

                  Any funds held by Banca del Gottardo which will not be used as
                  a consequence of Coupons and Notes not having been collected
                  within the relevant period described by the Statute of
                  Limitations (as referred to in Section 11 of the Terms of the
                  Notes), shall be held by Banca del Gottardo at the disposal of
                  the Company. Banca del Gottardo shall promptly after the
                  expiry of the relevant period inform the Company about the
                  respective amount.

                  The risk of any exchange loss on the transfer of funds so held
                  by Banca del Gottardo from Banca del Gottardo to the Company
                  shall be borne by the Company, provided the transfer is made
                  by order of, or with the consent of, the Company.

           (2)    COMMISSIONS AND EXPENSES

                  The Company will pay to Banca del Gottardo for the servicing
                  of the Notes a commission of

                  - 0.25% on the face amount of Coupons to be paid and
                  - 0.125% on the principal amount of Notes redeemed.

           (3)    MODALITIES

                  Any transfer by the Company as per (1) and (2) above, shall be
                  made in Swiss Francs freely disposable, without any
                  restrictions, and whatever the circumstances may be,
                  irrespective of the nationality or domicile of the holder of
                  Notes and/or Coupons, and without requiring any affidavit, or
                  the fulfilment of any other formality.

           (4)    PAYING AGENCY

                  The Company hereby appoints Banca del Gottardo as sole Paying
                  Agent (the "Paying Agent") and Banca del Gottardo agrees to
                  pay to the Noteholders all amounts to become due under the
                  Notes.

                  The Company undertakes, in connection with the Issue, not to
                  appoint any institutions as paying agent without the consent
                  of Banca del Gottardo, which consent shall not be unreasonably
                  withheld and not to pay to other banks any commission or
                  remuneration for the payment of interest or principal on the
                  Notes.

XI.        CANCELLATION OF NOTES AND COUPONS

           destruction took place and the names of the persons witnessing such
           destruction.

           Banca del Gottardo reserves the right to record cashed Coupons as
           well as redeemed, repaid, converted or replaced Notes on video tape
           or other data carriers and to store them in this way instead of
           keeping them physically during the period prescribed by law and to
           destroy them subsequently. This reproduction of Coupons and/or Notes
           will remain in safekeeping at Banca del Gottardo during the statutory
           limitation.

           If any sum due from the Company in favour of the Paying Agent has to
           be converted from Swiss Francs (the "first currency") into another
           currency (the "second currency") for the purpose of (i) making or
           filing a claim or proof against the Company, (ii) obtaining an order
           or judgment in any court or other tribunal or (iii) enforcing any
           order or judgment given or made in relation hereto, the Company shall
           indemnify and hold harmless Banca del Gottardo from and against any
           loss suffered as a result of any discrepancy between (a) the rate of
           exchange used for such purpose to convert the sum in question from
           the first currency into the second currency and (b) the rate or rates
           of exchange at which Banca del Gottardo may in the ordinary course of
           business purchase the first currency with the second currency upon
           receipt of a sum paid to them in the second currency in satisfaction
           in whole or in part of any such order, judgment, claim or proof.

           This indemnity shall constitute a separate and independent obligation
           from the other obligations contained herein, shall give rise to a
           separate and independent cause of action and shall apply,
           irrespective of any waiver granted by Banca del Gottardo from time to
           time and shall continue in full force and effect notwithstanding any
           judgment or order for a liquidated sum or sums in respect of amounts
           due hereunder or under any such judgment or order. Any such loss or
           damage aforesaid shall be deemed to constitute a loss suffered by
           Banca del Gottardo and no further proof or evidence of any actual
           loss shall be required by the Company.

                                                                       ANNEX A

                 TERMS OF THE "CONVERTIBLE NOTES" OF THE COMPANY

(1)    FORM AND DENOMINATION

        The Notes are issuable in bearer form in the denominations of CHF
        50'000.-- nominal amount each, with interest coupons (the "Coupons")
        attached. The Notes will be represented solely by a permanent Global
        Note (the "Permanent Global Note"), without interest coupons, to be
        deposited by the Company with Banca del Gottardo on the Payment Date.
        Each holder of a Note or Coupon, retains a co-ownership in the Permanent
        Global Note to the extent of his claim against the Company. EXCEPT AS
        PROVIDED BELOW, NO PRINTING OF NOTES AND COUPONS WILL OCCUR. HOLDERS OF
        NOTES AND COUPONS, THEREFORE, DO NOT HAVE THE RIGHT TO REQUEST THE
        PRINTING AND DELIVERY OF INDIVIDUAL NOTES AND COUPONS. The Notes are
        issued in the initial aggregate principal amount of three million Swiss
        Francs (CHF 3'000'000.--).

        The Permanent Global Note will remain in safekeeping with Banca del
        Gottardo during the entire duration of the issue and until the complete
        redemption of the Notes.

        Should the definitive Notes and Coupons be printed, the Notes shall be
        evidenced by bearer Notes with Coupons attached in the denomination of
        CHF 50'000.-- nominal and multiples thereof.

       Should Banca del Gottardo deem the printing of the Notes with Coupons
       attached to be necessary or useful, or if the presentation of definitive
       Notes and Coupons is required by Swiss or foreign laws in connection with
       the enforcement of rights (e.g. in cases of bankruptcy, consolidation or
       reorganization of the Company), Banca del Gottardo will provide for such
       printing without cost for the holders of the Notes and Coupons. Should
       the definitive Notes and Coupons be printed, Banca del Gottardo will then
       exchange the Permanent Global Note (deposited as above provided) as soon
       as possible against the definitive Notes and Coupons. The Company has
       irrevocably authorized Banca del Gottardo to provide for the printing of
       the definitive Notes and Coupons on its behalf.

       The Permanent Global Note may be exchanged, as a whole or in part, for
       appropriate definitive Notes, if printed, in bearer form in denominations
       of CHF 50'000.-- with the Coupons attached, not earlier than 1 year after
       the later of the date on which the Notes are first offered or the Payment
       Date. Such exchange shall be made upon certification that the beneficial
       owners of the Notes either (i) are not United States persons or U.S.
       persons or (ii)

<PAGE>

       are financial institutions (as defined in United States Treasury
       Regulation Section 1.165-12(c)(1)(v)) located outside the United
       States that are not United States persons and that have purchased such
       Notes for purposes of resale during the Restricted Period and that
       certify that they have not acquired the Notes for purposes of resale
       directly or indirectly to a United States person or to a person within
       the United States.

       For purposes hereof, (i) the term "Restricted Period" means the period
       beginning on the earlier of the first date that the Notes are offered or
       the date on which the Notes are issued (the "Payment Date") and ending on
       the date one (1) year after the later of the date upon which the Notes
       were first offered or the date of closing of this offering, (ii) the term
       "United States" means the United States of America (including the States
       and the District of Columbia), its possessions, its territories and other
       areas subject to its jurisdiction, (iii) the term "United States person"
       means a citizen or resident of the United States, a corporation,
       partnership or other entity created or organized in or under the laws of
       the United States or any political subdivision thereof, or an estate or
       trust the income of which is subject to United States federal income
       taxation regardless of its source and (iv) the term "U.S. person" has the
       meaning set forth in Sections 230.901 through .904 of Title 17 of the
       United States Code of Federal Regulations ("Regulation S").

       Until such time as and if and when the definitive Notes and Coupons have
       been issued, the expressions "Notes" and "Coupons" mean and include
       co-ownership under the Permanent Global Note and the expressions "holder
       of Note" and "holder of Coupon" shall mean and include any person
       entitled to co-ownership and any further benefit under the Permanent
       Global Note.

(2)    INTEREST

       The Notes bear interest from the Payment Date at the rate of 4% per
       annum, payable semi-annually in arrear on April 29 and October 29 of each
       year until maturity (the "Coupon Due Dates"), the first time on April 29,
       2000. Such interest is payable in Swiss Francs. Each Note will cease to
       bear interest on the date on which they become due for redemption or
       repayment unless payment of principal and/or premium (if any) is
       improperly withheld or refused or default is otherwise made in respect of
       such payment. In such event, interest will continue to accrue (as well
       after as before any judgment) up to but exluding the date on which
       payment in full of the principal of such Note is made or (if earlier) the
       date on which, payment in full of the principal thereof having been
       received by Banca del Gottardo, notice to that effect shall have been
       given to the holders of the Notes. Interest is computed on the basis of a
       360-day year of twelve 30-day months.

<PAGE>

(3)    REPAYMENT

       The Company undertakes to repay the principal amount of the Notes, unless
       previously redeemed, without any previous notice on October 29, 2003.

(4)    OPTIONAL REDEMPTION AND CONVERSION

       The Company reserves the right to call all, but not part, of the
       outstanding Notes for redemption on March 1, 2000, or thereafter up to
       the close of business on October 22, 2003, at a price of 110% of the
       principal amount thereof, together with interest accrued to the date of
       such redemption provided that the average of the daily closing sales
       prices of a Share for a period of 30 consecutive trading days, the last
       day of which trading days is not more than 10 days prior to the day upon
       which the Company sends a notice to Banca del Gottardo of its intention
       to redeem the Notes under this sub-section (a), is at least 200% of the
       Conversion Price, being initially USD 3.75 per Share ( the "Conversion
       Price), in effect on such last day (taking into account any retroactive
       adjustment not then reflected in the Conversion Price, whereby such
       adjustment shall be calculated pursuant to the Conversion Provisions,
       available at Banca del Gottardo). The closing sales price for any day
       shall be the average of the closing prices on the New York Stock Exchange
       and if not listed thereon, the average of the closing bid and asked
       prices on the National Association of Securities Dealers Automated
       Quotation (NASDAQ). All outstanding Notes will become due 60 days after
       receipt of the aforesaid notice of early redemption by Banca del
       Gottardo.

       As long as the Shares are listed on a stock exchange or exchanges in the
       United States of America, reference in this sub-section (a) to the sales
       price for any day shall be deemed to refer to the closing price (regular
       way) of a Share as reported by the principal stock exchange on which the
       Shares are listed for such day, or the average of closing bid and asked
       prices on NASDAQ. If no such sales price is reported for one or more
       trading days, such day or days shall not be deemed as trading day or days
       and shall be disregarded in the calculation of the said 30 trading day
       period.

(5)    PAYMENTS

       Payments with respect to the Notes and Coupons shall be made in Swiss
       Francs against presentation and surrender of such Notes or Coupons in the
       manner specified below. Such payments shall be made without cost to the
       Noteholders, without any limitations and under all circumstances
       notwithstanding any transfer restrictions, regardless of any bilateral or
       multilateral payment or clearing agreement in existence between the
       United States of America and the Swiss Confederation, irrespective of the
       nationality, residence or domicile of any of

<PAGE>

       the Noteholders and without requiring any affidavit or the fulfillment
       of any formalities. The funds required for the payment of principal
       and interest shall be made available to Banca del Gottardo in
       Switzerland as Paying Agent by the Company prior to each Coupon Due
       Date. The receipt of the funds by Banca del Gottardo in Switzerland
       shall release the Company from its obligations in respect of the
       payments due on the respective dates for principal and interest.

       Banca del Gottardo will arrange for payment of such funds as and when due
       to the holders of Notes and Coupons. Notes and coupons may be presented
       for payment at the principal amount printed on the Notes and the amount
       of interest printed on the Coupons only at the offices in Switzerland of
       Banca del Gottardo. No payment on the Notes or Coupons will be made by
       transfer to an account in, or by mailing to an address in, the United
       States.

(6)    TAX STATUS

       All payments of principal and interest on the Notes and Coupons by the
       Company shall be made without deduction for or on account of any present
       or future tax, assessment or other governmental charge ("Taxes") imposed
       upon such payment by the United States of America or any political
       subdivision or taxing authority thereof or therein (the "United States").
       If the Company shall at any time be required by law to withhold any such
       Taxes, the Company will pay as additional amounts to Banca del Gottardo
       for the account of the holders of Notes and Coupons, such amounts as may
       be necessary so that every net payment on each Note or Coupon, after
       withholding for or on account of any such Taxes (including any backup
       withholding tax or similar charge that may be required in order for such
       payment to be made without any certification or disclosure of the
       nationality, residence or identity of the beneficial owner of such Note
       or Coupon) will not be less than the amount provided in such Note or
       Coupon to be then due or payable; provided, however, that the Company
       will not be required to pay such additional amounts for or on account of
       any such Taxes that are imposed (i) otherwise than by withholding from a
       payment on a Note or Coupon, (ii) upon a holder of a Note or Coupon who
       is subject to taxation by the United States for any reason other than
       such holder's ownership or receipt of payments in respect of such Note or
       Coupon, or (iii) on interest or principal received by a holder of a Note
       or Coupon which is (a) a "10-per cent. shareholder" of the Company within
       the meaning of section 871(h) (3) (B)(a) of the Code, (b) a bank or an
       extension of credit made pursuant to a loan agreement entered into in the
       ordinary course of its trade or business, (c) a controlled foreign
       corporation which is related to the Company under section 864(d)(4) of
       the Code, (d) other than a nonresident individual or a foreign
       corporation (as determined under United States tax principles) with
       respect to the United States, or (e) a holder whose Note or Coupon is
       presented for retirement or redemption, or payment is otherwise made,
       other than outside the United States as provided in United States
       Treasury Regulations. Any reference in this Note to the payment of
       principal or

<PAGE>

       interest shall be deemed to include payment of the additional amounts
       payable pursuant to the provisions of this paragraph.

       If, as the result of any change in, enactment of, or amendment to any
       laws or regulations of the United States or any political subdivision or
       taxing authorities thereof affecting taxation, or any change in the
       official application of such laws or regulations, or any change in,
       execution of or amendment to any treaty or treaties affecting taxation to
       which the United States is a party, it is determined by the Company that
       it would be required at any time to pay additional amounts pursuant to
       the preceding paragraph, the Company is entitled to redeem the Notes, as
       a whole but not in part, on giving not more than 60 days' but not less
       than 30 days' prior notice to Banca del Gottardo, on or after April 29,
       2000 at par.

       Notice of redemption shall be given by the Company in writing to Banca
       del Gottardo and such notice so given shall constitute good and
       sufficient notice and shall be binding upon all holders of the Notes,
       regardless of who they may be or where they may be located.

       Banca del Gottardo shall as soon as practicable notify the Noteholders of
       such redemption in accordance with Section 12 hereof.

       The Company has been advised by Banca del Gottardo that pursuant to the
       Swiss federal laws at present in force, interest payments on the Notes
       are not subject to Swiss withholding tax.

(7)    AUTHORIZATIONS

       The Company has confirmed to Banca del Gottardo that no authorizations or
       approvals are required under the laws of the United States for
       performance of its obligations hereunder, except for the registration
       requirements provided for herein.

(8)    STATUS OF THE NOTES AND NEGATIVE PLEDGE

       The Notes constitute unsecured direct obligations of the Company, ranking
       equally with other unsecured and unsubordinated indebtedness for borrowed
       money of the Company.

       So long as any Note remains outstanding the Company will not at any time
       pledge or otherwise subject to any lien any of its property or assets
       (other than (i) liens incurred in the ordinary course of business, as for
       example, installment payment purchases of equipment or other assets used
       in the Company's business and (ii) liens not incurred in the ordinary
       course of business not exceeding USD 250'000.-- in the aggregate),
       without thereby expressly

<PAGE>

       securing the Notes equally and ratably with any and all other
       obligations and indebtedness secured by such pledge or other lien.

(9)    CONVERSION

       Exhibit 1 to Annex E attached to the Agreement dated October 26, 1999 and
       entered into between the Company and Banca del Gottardo, which is
       available for inspection at the Head Office in Lugano of Banca del
       Gottardo, as Conversion Agent for the Notes, contains full provisions
       relevant to conversion of the Notes into initially 8'800 Shares of Common
       Stock (being the equivalent of USD 33'000.-- divided by USD 3.75
       ("Conversion Price"), the initial conversion price per Share, the
       "Conversion Amount") which are to be duly registered under the 1933
       Securities Act. The following is a summary of such provisions:

       The holder of 1 Note or more will be entitled at any time on and after
       March 1, 2000 up to the close of business on October 22, 2003, subject to
       prior redemption, to convert the Notes, at the Conversion Amount thereof,
       into initially 8'800 freely transferable and non-restricted (such
       non-restriction being subject to the effectiveness of a registration
       statement under the U.S. securities laws covering such common stock, if
       required,) shares of Common Stock of the Company, Pricesubject to
       adjustment as described below. No payment or adjustment will be made on
       conversion of any Note for interest accrued thereon or dividends on any
       Common Stock issued, except that accrued interest will be paid on the
       conversion of any Note which has been called for redemption prior to the
       conversion date. The Company is not required to issue fractional shares
       of Common Stock upon conversion of Notes and, in lieu thereof, will pay a
       cash adjustment based upon the market price of the Common Stock on the
       last trading day prior to the date of conversion. In the case of Notes
       called for redemption, conversion rights will expire at the close of
       business on the fifth business day prior to the redemption date. Notes
       may be presented for conversion only to an office of Banca del Gottardo
       outside the United States and Banca del Gottardo will deliver Common
       Stock or other consideration received upon conversion only to an account
       or address outside the United States.

       The Conversion Price is subject to adjustment in the following events
       occurring after October 29, 1999:

       -   the issuance of stock of the Company as a dividend or distribution
           on the Common Stock;

       -   subdivisions of outstanding shares of the Common Stock into a
           greater number of shares;

       -   combinations of outstanding shares of Common Stock into a smaller
           number of shares;

<PAGE>

       -   reclassification of the Common Stock into other shares of the
           Company's capital stock;

       -   issuance to all holders of Common Stock of certain rights entitling
           them to subscribe for Common Stock at a price per share less than the
           current market price but not for shares issuable under the Company's
           stock option and stock purchase plans; and

       -   the distribution to all holders of Common Stock of debt securities or
           assets of the Company or rights to purchase assets or debt securities
           of the Company (excluding cash dividends or distributions from
           retained earnings).

       No adjustment in the Conversion Price will be made unless such adjustment
       would require an increase or decrease of at least one Share in the
       Conversion Price then in effect; but any adjustment that would otherwise
       be required to be made shall be carried forward and taken into account in
       any subsequent adjustment. No adjustment need be made for rights to
       purchase Common Stock pursuant to a Company dividend or interest
       reinvestment plan. If the Company consolidates or merges into or
       transfers or leases all or substantially all of its assets to any person,
       or is a party to a merger that reclassifies or changes its outstanding
       Common Stock, the Notes will become convertible into the kind and amount
       of securities, cash or other assets which the Holders would have owned
       immediately after the transaction if the holders had converted the Notes
       immediately before the effective date of the transaction.

(10)   EVENTS OF DEFAULT

       Subject to the provisions of Section 15, Banca del Gottardo as regards
       all Notes or Holders having 10% or more of the aggregate principal amount
       of all Notes outstanding shall have the right to declare by notice to the
       Company the Notes held by such Holder, plus accrued interest, to be due
       and payable if any of the following events of default shall occur:

       (a)    default in the payment of principal, or, for a period of 15 days
              after due and payable, in the payment of interest on any Note; or

       (b)    default in the performance or observance in any material respect
              of any covenant or agreement of the Company in the Notes if such
              default continues for a period of 30 days after notice thereof has
              been given by Banca del Gottardo to the Company; or

       (c)    a default shall occur under any evidence of indebtedness for money
              borrowed by the Company or under any instrument under which there
              may be issued or by which there may be secured or guaranteed any
              indebtedness for money borrowed by the Company, which default
              involves the failure to pay when due (after any applicable grace
              period

<PAGE>

              and subject to any extension or postponement of such maturity),
              or results in the acceleration of, indebtedness in an amount in
              excess of USD 500'000.-- without such indebtedness having been
              discharged or such default or acceleration having been waived,
              rescinded or annulled, within a period of 30 days after notice
              thereof shall have been given by Banca del Gottardo to the
              Company; or

       (d)    the entry of a decree or order in respect of the Company in an
              involuntary case under any bankruptcy, insolvency or other similar
              law, or appointing a receiver, liquidator, trustee or other
              similar official of the Company or for any substantial part of its
              property, or ordering the winding up or liquidation of its
              affairs, and the continuance of any such decree or order unstayed
              and in effect for a period of 45 consecutive days; or

       (e)    the Company shall commence a voluntary case under any bankruptcy,
              insolvency or other similar law, or consent to the appointment of
              or taking possession by a receiver, liquidator, trustee or other
              similar official, of the Company or for any substantial part of
              its property, or the making by it of a general assignment for the
              benefit of creditors, or if it shall fail generally to pay its
              debts as they become due, or shall take any corporate action in
              furtherance of any of the foregoing; or

       (f)    if the Company shall merge or consolidate, or sell or convey all
              or substantially all of its assets to, any other corporation,
              unless (i) the Company is the surviving corporation, or (ii) the
              surviving or transferee corporation expressly assumes all
              obligations of the Company under the Notes by supplemental
              agreement, confirmed by an opinion of U.S. counsel reasonably
              satisfactory to Banca del Gottardo and the Company, or (iii) the
              Company or the surviving or transferee corporation irrevocably
              deposits in trust with Banca del Gottardo, money or U.S.
              government obligations sufficient to pay principal and interest on
              the Notes to maturity.

       Upon the occurrence of an event of default, the Company shall promptly
       give notice thereof to Banca del Gottardo which shall publish such notice
       of default in accordance with Section 12 hereof. Banca del Gottardo shall
       in relation to any event of default have no other obligation than the
       publication of such event of default.

       The principal amount of all Notes declared to be due and payable plus
       accrued interest thereon shall become due and payable 15 days after
       notice to the Company by Banca del Gottardo or by each Holder of such
       event of default; provided, however, that such declaration shall be
       rescinded if, within 15 days of such notice, such event of default shall
       have been remedied by payment, in the case of a payment default, or in a
       manner reasonably satisfactory to Banca del Gottardo.

       previously taken action pursuant to such Section 15.

(15)   NOTEHOLDERS' MEETING

       a)     A meeting of the Holders (hereinafter called a "Meeting") may be
              convened by the Company or shall be convened by the Company if so
              requested by Notes representing not less than 25% of the aggregate
              principal amount of all Notes outstanding under the Terms of the
              Notes (i) after the event of default shall have occurred and be
              continuing to consider a waiver of an event of default or any
              modification or amendment of the provisions of the terms of the
              Notes, or (ii) a substitution of Banca del Gottardo.

              The cost and expenses of a Meeting shall be borne by the Company.

<PAGE>

       b)     Notice of the Meeting specifying the place, day and hour of the
              Meeting shall be given at least 20 days prior to the proposed date
              thereof (exclusive of the day on which the notice is given and the
              day on which the Meeting is to be held) in accordance with Section
              12 hereof. Such notice shall state generally the nature of the
              business to be transacted at the Meeting thereby convened but
              (except for an Extraordinary Resolution (as defined below)) it
              shall not be necessary to specify in such notice the terms of any
              resolution to be proposed.

       c)     The Meeting shall be held in Lugano and shall be chaired by a
              representative of the Company or if such representative of the
              Company shall not be present within 30 minutes after the time
              appointed for the holding of the Meeting, the Noteholders present
              shall choose one of their members to be chairman. The Meeting
              shall be conducted in the English language exclusively.

       d)     Resolutions shall only be passed if a quorum of two or more
              persons holding 25% or more of the aggregate principal amount of
              all Notes outstanding are present. The quorum at any Meeting for
              passing an Extraordinary Resolution shall be two or more persons
              holding two-thirds or more of the aggregate principal amount of
              all Notes outstanding. Resolutions shall be passed if approved by
              the absolute majority of votes cast save that an Extraordinary
              Resolution shall be passed only if approved by three-fourths or
              more of votes cast. Any resolution passed at a Meeting duly
              convened and held in accordance with the terms of the Notes shall
              be binding upon all the Holders, whether present or not present at
              such Meeting and whether or not voting, and upon all the holders
              of coupons.

       e)     If within 30 minutes after the time appointed for any such Meeting
              a quorum is not present, the Meeting shall, if convened upon the
              request of Holders, be dissolved. In any other case, it shall
              stand adjourned for such period being not less than 14 days nor
              more than 28 days, and at such place as may be appointed by the
              Company. At such adjourned Meeting, two or more persons present
              holding 10% or more of the aggregate principal amount of all Notes
              outstanding shall form a quorum, provided that if the business of
              such adjourned Meeting includes consideration of a proposed
              Extraordinary Resolution, the quorum shall be two or more persons
              present holding one-third or more of the aggregate principal
              amount of all Notes for the time being outstanding.

       f)     If within 30 minutes after the time appointed for any such
              adjourned Meeting the respective quorum is not present the Meeting
              shall stand further adjourned for such period being not less than
              14 days nor more than 28 days, and at such place as may be
              appointed by the Company and at such further adjourned Meeting two
              or more persons present holding any Notes outstanding (whatever
              the principal amount of the Notes so

<PAGE>

              held by them) shall form a quorum, provided that if the
              business of such further adjourned Meeting includes
              consideration of a proposed Extraordinary Resolution, the
              quorum shall be two or more persons present holding one-third
              or more of the aggregate principal amount of all Notes for the
              time being outstanding.

       g)     Notice of any adjourned Meeting or further adjourned Meeting shall
              be given in the same manner as notice of an original Meeting and
              such notice shall state, in the case of an adjourned Meeting, that
              two or more persons present holding 10% (or in the case of a
              Meeting the business of which includes consideration of a proposed
              Extraordinary Resolution, one-third) or more of the aggregate
              principal amount of all Notes for the time being outstanding will
              form a quorum, or, in the case of a further adjourned Meeting,
              that two or more persons present holding any Notes outstanding (or
              in the case of a Meeting the business of which includes the
              consideration of a proposed Extraordinary Resolution, two or more
              persons present holding one-third or more of the aggregate
              principal amount of all Notes for the time being outstanding),
              shall form a quorum.

       h)     The voting rights of the Holders shall be determined according to
              the principal amount of Notes held, each Note with a principal
              amount of CHF 50'000.-- giving the right to one vote. Holders of
              the coupons shall not have any voting rights. Notes held by or on
              behalf of the Company shall have no voting rights and shall be
              disregarded for the purpose of this Section 15, save that the
              Company shall be entitled to vote in respect of Notes held by it
              for the benefit of and at the direction of an independent third
              party. In the case of an equality of votes the chairman shall have
              a casting vote in addition to the vote or votes (if any) to which
              he may be entitled as a Holder.

       i)     Any director or officer of the Company and its lawyers and any
              other person authorized on its behalf by it may attend and speak
              at any Meeting.

       j)     The Meeting shall have the following powers exercisable by
              Extraordinary Resolution with the consent of the Company:

              (i)    extension of the date fixed for final maturity of the
                     Notes;

              (ii)   reduction or cancellation of the principal payable on
                     the Notes;

              (iii)  reduction or cancellation of the rate or amount payable, or
                     extension of the date of payment, in respect of any
                     coupons;

<PAGE>

              (iv)   alteration of the majority required to pass an
                     Extraordinary Resolution; and

              (v)    waiver of any Event of Default.

       k)     Any reference in these Terms of the Notes to an "Extraordinary
              Resolution" shall be construed as references to resolutions of the
              Holders passed in accordance with the foregoing provisions of this
              Section 15 with respect to any of the matters stated in
              sub-section j) above.

(16)   APPLICABLE LAW AND JURISDICTION

       The terms, conditions and form of the Notes and coupons (the English
       language version of which shall govern) shall be governed by and
       construed in accordance with Swiss law.

       Any action or proceedings against the Company relating to the Notes may
       be brought and enforced in the ordinary courts of the Canton of Ticino,
       venue being in the City of Lugano, or, if such courts fail to grant
       jurisdiction in the ordinary courts of the Canton of Basle-City, venue
       being in Basle, and the Company hereby irrevocably submits to the
       jurisdiction of such courts in respect of any such action or proceeding,
       with the right to appeal, as provided by law, to the Swiss Federal Court
       in Lausanne, the judgment of which shall be final. Solely for that
       purpose, the Company hereby elects legal and special domicile at the
       office of Banca del Gottardo, Viale Stefano Franscini 8, 6901 Lugano,
       Switzerland. Banca del Gottardo shall notify the Company promptly upon
       receipt of any notice by it in its capacity as the Company's agent for
       service of process. The Company covenants that so long as any Notes are
       outstanding it will maintain an agent for service of process in
       Switzerland. The aforementioned jurisdiction shall also be valid for the
       cancellation and replacement of lost, stolen, defaced, mutilated or
       destroyed Notes and coupons. Payment effected to a holder of Notes who
       has been identified as the legitimate holder of a Note or coupon by a
       final judgment of a Swiss court shall release the Company from its
       payment obligations under such Note or coupon.

       Any Noteholder shall also have the right to bring any legal action or
       proceeding against the Company in respect of a Note or coupon and all
       covenants contained therein in any state or federal court in the Country
       of Franklin, Ohio, in the United States of America which may have
       jurisdiction.

                              CONVERSION PROVISIONS

The following are the provisions for the conversion (the "Conversion
Provisions") of the CHF 3'000'000.-- 4% Convertible Notes due October 29, 2003
of Bigmar, Inc., Johnstown, Ohio 43031, U.S.A., (the "Company") into shares of
the common stock of the Company. Unless otherwise defined herein, the terms used
herein have the meanings ascribed to them in the Note Purchase, Paying and
Conversion Agency Agreement and the Conversion Agency Agreement (the "Agency
Agreement") dated as of October 26, 1999, between the Company and Banca del
Gottardo.

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

ARTICLE 1

Conversion Right

1.1.   Subject to and upon compliance with these Conversion Provisions, the
       holder of any Note (a "Noteholder") will have the right at any time on
       and after March 1, 2000 up to the close of business of banks in Lugano on
       October 22, 2003, or, in case the Notes are called for redemption in
       accordance with Section 4 of the Terms of the Notes, then prior to the
       close of business of banks in Lugano on the earlier of October 22, 2003
       and the fifth business day preceding the date fixed for redemption, but
       in no event thereafter, to convert USD 33'000.-- (the Conversion Amount)
       of one Note or more Notes into initially 8'800 freely transferable and
       non-restricted (such non-restriction being subject to the effectiveness
       of a registration statement under the U.S. securities laws covering such
       common stock) shares of common stock which are duly registered under the
       1933 Securities Act, with par value USD 0.001 per share (such presently
       authorized capital stock and any other stock into which such presently
       authorized common stock may hereafter be changed, the "Common Stock"), of
       the Company, calculated as to each conversion to the greatest number of
       full Shares, disregarding fractions, at a price of initially USD 3.75 per
       share, such price being subject to adjustment in certain instances as
       provided in Article 2 hereafter (as so adjusted from time to time, the
       "Conversion Price"). Fractions of a share will not be issued on
       conversion; provided, however, that if a Noteholder at any one time
       delivers more than one Note for conversion, the number of Shares issued
       shall be calculated on the basis of the aggregate principal amount of the
       Notes so delivered. A cash adjustment shall be paid in respect of any
       fractional Share which would otherwise be issuable upon conversion of any
       Note in an amount in Swiss Francs based upon the market price of the
       Common Stock on the last trading day prior to the date of conversion.
       Cash adjustments for fractional shares will not be made for amounts less
       than five U.S. Dollar/seven Swiss Francs.

<PAGE>

1.2.   In order to exercise the right of conversion, a Noteholder shall (a)
       deliver the Note or Notes to be converted during normal business hours,
       accompanied by the conversion notice in the form obtainable from the
       Conversion Agent (the "Conversion Notice") to any Conversion Agent and
       (b) pay to the Conversion Agent any stamp or other taxes that may be
       payable in Switzerland on such conversion. Each Note, if printed,
       delivered for conversion must be delivered with all unmatured coupons
       attached and/or with an amount equal to the face value of any missing,
       unmatured coupons. Such missing, unmatured coupons shall be paid by Banca
       del Gottardo upon subsequent presentation thereof, provided they shall
       not have become barred pursuant to Section 11 of the Terms of the Notes.

1.3.   The Conversion Agent undertakes to:

       (a)    make available to Noteholders the Conversion Notice in such form
              as may from time to time be agreed by the Company and the
              Conversion Agent;

       (b) upon receipt of a Conversion Notice from a Noteholder:

              (i)    verify that (A) the Conversion Notice has been duly
                     completed and signed by or on behalf of the Noteholder
                     named therein, (B) the Conversion Notice is accompanied by
                     all Notes, if printed, to which it relates and all
                     unmatured coupons appertaining to such Notes and/or an
                     amount equal to the face value of any missing unmatured
                     coupons and (C) the amount of any stamp or other taxes
                     payable by the Noteholder has been paid; and

              (ii)   endorse the Conversion Notice;

       (c)    imprint or stamp all Notes, if printed, submitted to it for
              conversion, and all unmatured coupons attached thereto, in
              accordance with Article 4 of the Agency Agreement promptly upon
              satisfaction by the Noteholder of all conditions precedent to the
              conversion; and

       (d)    dispatch within two business days after satisfaction by the
              Noteholder of all conditions precedent to the conversion to the
              relevant tax authorities, payment in respect of any stamp or other
              taxes payable on the conversion, in accordance with the laws of
              Switzerland.

1.4.   The Conversion Agent shall promptly, upon the later of the date of
       receipt of the Conversion Notice and the satisfaction of all other
       conditions precedent to the conversion stated above, endorse the
       Conversion Notice and notify the Company and the Stock Transfer Agent of
       the

<PAGE>

       Company (at present American Stock Transfer & Trust Company, 40 Wall
       Street, New York, NY 10005, U.S.A.), by facsimile, telex or cable of
       (a) the principal amount and serial numbers of the Notes deposited for
       conversion, (b) the number of Shares issuable upon conversion of such
       Notes and (c) the name and address of each person (the "Shareholder")
       to whom such Shares are to be issued. Such conversion shall become
       effective at the close of business on the date (the "Conversion Date")
       on which the Company shall have received at its principal executive
       offices, during normal business hours, from the Conversion Agent a
       telex or cable notification. If such facsimile, telex or cable
       notification is received after the close of business on such date, the
       Conversion Date will be the immediately following business day. At
       such Conversion Date the rights of the holder (other than the Company)
       of a Note shall cease and the Shareholder shall be deemed to have
       become the holder of such Shares.

1.5.   As soon as practicable on or after the Conversion Date, but in no event
       later than seven business days thereafter, the Company shall (a) cause
       the Shareholder to be registered as the owner of the Shares issued upon
       conversion of such Shareholder's Notes in the register of Shareholders of
       the Company, (b) make available, or cause the Stock Transfer Agent to
       issue, a certificate or certificates for such Shares registered in the
       name of the Shareholder (together with any other securities, properties
       or cash deliverable at the Conversion Date) and (c) at the request of the
       Shareholder, cause the Stock Transfer Agent to forward, at the risk and
       expense and for account of such Shareholder, such certificate or
       certificates (together with any other securities, properties or cash
       deliverable upon conversion) to such person or persons at the address
       specified in the Conversion Notice, together with such assignments and
       other documents, if any, as may be required by law to effect the transfer
       thereof with full benefits under the laws of the applicable jurisdiction
       of the United States of America.

1.6.   The Company covenants that:

       (a)    so long as any Notes are outstanding, it shall keep available
              authorized shares of Common Stock sufficient to permit all Notes
              outstanding and unconverted to be converted in accordance with
              these Conversion Provisions;

       (b)    all shares of Common Stock delivered upon conversion of Notes as
              provided herein will be validly issued, fully-paid and
              non-assessable;

       (c)    it shall file, on or before March 1, 2000, if required, any
              registration under the United States securities laws that may be
              required before the Shares can be delivered upon conversion of the
              Notes and freely marketed in the United States.

<PAGE>

1.7.   Shares issued upon conversion and registered in the name of the
       Shareholder shall be freely transferable and non-restricted and shall be
       entitled to receive all dividends paid on such Common Stock on or after
       the Conversion Date, except for dividends payable to Shareholders
       registered as such as of a record date occurring prior to the Conversion
       Date. No payments shall be made upon conversion for interest accrued
       since the Coupon Due Date next preceding the Conversion Date.

1.8.   Notes may be presented for conversion only to an office of the Conversion
       Agent outside the United States. The Company and the Conversion Agent
       will deliver Common Stock or other consideration received upon conversion
       only to an account or address outside the United States.

ARTICLE 2

The Conversion Price shall be subject to adjustments in the following
circumstances occurring after October 29, 1999:

2.1.   In case the Company shall hereafter (i) pay a dividend on its Common
       Stock in shares of its Common Stock or make a distribution in shares of
       its Common Stock with respect to its outstanding Common Stock, (ii)
       subdivide its outstanding shares of Common Stock into a greater number of
       shares of Common Stock or (iii) combine its outstanding shares of Common
       Stock into a smaller number of shares of Common Stock, the Conversion
       Price in effect at the time of the record date for such dividend or of
       the effective date of such subdivision or combination shall be determined
       by multiplying the Conversion Price in effect immediately prior to such
       record date or effective date by a fraction, the numerator of which shall
       be the total number of outstanding shares of Common Stock immediately
       prior to such record date or effective date, and the denominator of which
       shall be the total number of outstanding Common Stock immediately
       following such record date or effective date. Such adjustments made
       pursuant to this Section 2.1 shall be made successively whenever any
       event listed above shall occur.

2.2.   In case the Company shall fix a record date for the issuance of rights,
       options to all (but not less than all) holders of its outstanding Common
       Stock entitling them to subscribe for or purchase shares of Common Stock
       (or securities convertible into shares of Common Stock) at a price per
       share (or having a price per share, if a security convertible into Common
       Stock) less than the Current Market Price per share of Common Stock (as
       defined in Section 2.4) on such record date, the Conversion Price to be
       in effect after such record date shall be determined by multiplying the
       Conversion Price in effect immediately prior to such record date by a
       fraction, of which the numerator shall be the number of shares of Common
       Stock

<PAGE>

       outstanding on such record date plus the number of shares of Common
       Stock which the aggregate offering price of the total number of shares
       of Common Stock so to be offered (or the aggregate initial Conversion
       Price of the convertible securities so to be offered) would purchase
       at such Current Market Price and of which the denominator shall be the
       number of shares of Common Stock outstanding on such record date plus
       the number of additional shares of Common Stock to be offered for
       subscription or purchase (or into which the convertible security so to
       be offered are initially convertible). In case such subscription or
       exercise price may be paid in a consideration part or all of which
       shall be in a form other than cash, the value of such consideration
       shall be as determined by the Board of Directors of the Company.
       Shares of Common Stock owned by or held for the account of the Company
       or any majority-owned subsidiary shall not be deemed outstanding for
       the purpose of any such computation. Such adjustment shall be made
       successively whenever such a record date is fixed; and in the event
       that such rights are not so issued, the Conversion Price shall again
       be adjusted to be the Conversion Price which would then be in effect
       if such record date had not been fixed.

2.3.   In case the Company shall fix a record date for the making of a
       distribution to all (but not less than all) holders of shares of Common
       Stock of evidences of its indebtedness or assets (other than cash
       dividends or cash distributions payable out of surplus legally available
       for dividends under the laws of the jurisdiction of incorporation of the
       Company, dividends or distributions payable in shares of Common Stock as
       described in Section 2.1, or rights, options or convertible securities
       containing the right to subscribe for or purchase shares of Common Stock
       (excluding those referred to in Section 2.2)), the Conversion Price to be
       in effect after such record date shall be determined by multiplying the
       Conversion Price in effect immediately prior to such record date by a
       fraction, of which the numerator shall be the Current Market Price per
       share of Common Stock (as defined in Section 2.4) on such record date,
       less the fair market value per share (as determined by the Board of
       Directors of the Company, whose determination shall be conclusive, and
       described in a statement filed with Banca del Gottardo) of the portion of
       the assets or evidences of indebtedness so to be distributed, or of such
       rights, options, or convertible securities, applicable to one share of
       Common Stock, and of which the denominator shall be such Current Market
       Price per share of Common Stock. Such adjustment shall be made
       successively whenever such a record date is fixed; and in the event that
       such distribution is not so made, the Conversion Price shall again be
       adjusted to be the Conversion Price which would then be in effect if such
       record date had not been fixed. If any such rights, options, or
       convertible securities shall by their terms provide for an increase or
       increases, with the passage of time, in the amount of additional
       consideration per share of Common Stock payable to the Company upon the
       exercise or conversion thereof, the Conversion Price then in effect
       shall, forthwith upon any such increase becoming effective, be readjusted
       to reflect such increase.

2.4.   For the purpose of any computation under Sections 2.2 and 2.3, the
       "Current Market Price" means with respect to any Trading Day the last
       sale price (regular way) of the Common on such day as reported on the New
       York Stock Exchange Consolidated Tape (as published in the Wall Street
       Journal), or, if such Common Stock is not listed on the New York Stock
       Exchange, Inc. or reported on such Consolidated Tape, then the last sale
       price on such day on the principal domestic stock exchange on which such
       stock is then listed or admitted to trading, or, if no sale takes place
       on such day on such exchange, the average of the closing bid and asked
       prices on such day as officially quoted on such exchange, or, if such
       Common Stock is not then listed or admitted to trading on any domestic
       stock exchange but is quoted in the Smallcap System ("NASDAQ") of the
       National Association of Securities Dealers, Inc. Automated Quotation
       System ("NASDAQ"), then the Current Market Price for each such Trading
       Day shall be the last sale price on such day as quoted by NASDAQ, or, if
       no sale takes place on such day or if such Common Stock is neither listed
       or admitted to trading on any domestic stock exchange nor quoted on such
       National Market System, then the Current Market Price for each such
       Trading Day shall be the average of the reported closing bid and asked
       price quotations on such day in the over-the-counter market, as reported
       by NASDAQ, or, if not so reported, as furnished by the National Quotation
       Bureau, Inc., or, if such firm at the time is not engaged in the business
       of reporting such prices, as furnished by any similar firm then engaged
       in such business as selected by the Company, or if there is no such firm,
       as furnished by any member of the National Association of Securities
       Dealers, Inc. selected by the Company with the written approval of the
       Holders of the Notes convertible for a majority of the shares of Common
       Stock issuable under then outstanding Notes. If at any time such Common
       Stock is not listed on any domestic exchange or quoted in the domestic
       over-the-counter market, the Current Market Price shall be deemed to be
       an amount mutually agreed upon in writing between the Company and the
       Holder of this Note within fifteen days immediately following the date on
       which the Current Market Price is to be determined. If no agreement as to
       Current Market Price is determined as stated herein, (i) the Holder of
       this Note shall select an independent appraiser who shall determine the
       fair market value per share of the Common Stock which shall be the
       Current Market Price, provided the Company shall agree to such Current
       Market Price. If the Company shall not agree to the Current Market Price
       as determined in the preceding sentence then (ii) the Company and Banca
       del Gottardo shall each select an independent appraiser who shall,
       independently of the other appraiser, determine the fair market value of
       the Common Stock of the Company. If the value determined by the appraiser
       whose determination is the higher of the two appraisals does not exceed
       by more than ten percent (10%) the average of the values determined by
       each appraiser, then the Current Market Price shall be the average of the
       values determined by the two appraisers. If the value determined by the
       appraiser whose determination is the higher of the two appraisals does
       exceed by more than ten percent (10%) the average of the value determined
       by each appraiser, then the two appraisers shall select a third
       independent

<PAGE>

       appraiser who shall, independently of the other appraisals, determine
       the fair market value of the Common Stock. The value determined by the
       appraiser whose determination is the most discrepant from the average
       of the three appraisals shall be discarded, and the Current Market
       Price shall equal the average of the remaining two appraisals; except
       that in the event that the highest and lowest appraisals are equally
       discrepant from the average of the three appraisals, the Current
       Market Price shall be such average. The Company shall bear the
       expenses of all appraisals.

       For the purpose of this Section 2.4, "trading day" shall mean a day on
       which the securities exchange or on NASDAQ specified for purposes of this
       Section 2.4 shall be open for business or, if the shares of Common Stock
       shall not be listed on such exchange for such period, a day with respect
       to which quotations of the character referred to in the next preceding
       sentence shall be reported.

2.5.   In computing an adjustment in the Conversion Price pursuant to Sections
       2.1 to 2.3 above, shares of Common Stock not outstanding at the time of
       such computation shall be deemed outstanding to the extent that the
       Conversion Price has been previously adjusted to reflect the issuance of
       such shares of Common Stock or rights, options to subscribe for or
       purchase such shares of Common Stock.

2.6.   Except as stated in Sections 2.1, 2.2 and 2.3 above, the Conversion Price
       (except at the Company's option) shall not be adjusted for the issuance
       of shares of Common Stock of the Company whether or not at less than the
       Current Market Price or the current Conversion Price, whether for cash or
       property.

2.7.   No adjustment shall be made to the Conversion Price unless such
       adjustment would result in any increase or decrease of at least USD 0.05
       in the Conversion Price then in effect; provided, however, that any
       adjustments which by reason of this Section 2.7 are not required to be
       made will by carried forward and taken into account in any subsequent
       adjustment.

2.8.   All calculations under these Conversion Provisions shall be made to the
       nearest one U.S. cent, with 0.5 U.S. cent or more to be considered a full
       U.S. cent, or to the nearest one-hundredth of a share, as the case may
       be.

2.9.   Whenever the Conversion Price is adjusted as herein provided, the Company
       shall promptly send to Banca del Gottardo a certificate of the Company
       setting forth the Conversion Price after such adjustment and setting
       forth a brief statement of the facts requiring such adjustment and the
       date on which it becomes effective. The contents of any certificate
       required by this Section 2.9 may be transmitted by telex or cable, but
       shall be confirmed in writing as

<PAGE>

       hereinbefore provided. Banca del Gottardo may rely upon such
       certificate (or such transmission by cable or telex, whether or not so
       confirmed) as conclusive evidence of the correctness of the adjustment
       referred to therein.

2.10.  Notwithstanding the foregoing, no adjustment shall be made to the extent
       that it would reduce the Conversion Price to less than the par value of
       the shares of Common Stock (USD .01 at the date hereof).

2.11.  Anything in this Article 2 to the contrary notwithstanding, the Company
       shall be entitled, but shall not be required, to make such reductions in
       the Conversion Price in addition to those required by this Article as it,
       in its discretion, shall determine to be advisable.

2.12.  In any case in which this Article shall require that an adjustment be
       made retroactively immediately following a record date, the Company shall
       as promptly as practicable issue to the holder of any Note converted
       after such record date the shares of Common Stock and other common stock
       of the Company issuable on such conversion in excess of the shares of
       Common Stock and other common stock of the Company issuable on such
       conversion on the basis of the Conversion Price prior to such adjustment.

ARTICLE 3

3.1.   In the event that:

       (a)    the Company shall authorize the issuance to all holders of shares
              of Common Stock of rights, options to subscribe for or purchase
              any shares of Common Stock or any securities convertible into
              shares of Common Stock, or of any other subscription rights;

       (b)    the Company shall authorize the distribution to all holders of
              shares of Common Stock of evidences of its indebtedness or assets
              (other than cash dividends or cash distributions payable out of
              consolidated earnings or earned surplus or dividends payable in
              Common Stock);

       (c)    there shall be any consolidation or merger to which the Company is
              a party and for which approval of any shareholders of the Company
              is required, or there shall be the conveyance or transfer of all
              or substantially all of the properties and assets of the Company,
              or there shall be any reorganization or reclassification or change
              of outstanding Common Stock issuable upon the exercise of
              conversion rights hereunder (other than a change in par value, or
              from par value to no par value, or from no par value to par value,
              or as a result of a subdivision or combination);

<PAGE>

       (d)    there shall be voluntary or involuntary dissolution, liquidation
              or winding-up of the Company; or

       (e)    the Company proposes to take any action (other than the actions of
              the type described in Section 2.1) which would require an
              adjustment of the Conversion Price pursuant to Article 2;

       then the Company shall, at least 10 days prior to the applicable record
       date, provide written notice of such event to Banca del Gottardo stating
       (x) the record date in the United States of America as of which the
       holders of record of shares of Common Stock to be entitled to receive any
       such rights, warrants, or distributions are to be determined, or (y) the
       date in the United States of America on which such reorganization,
       consolidation, merger, conveyance, transfer, dissolution, liquidation or
       winding-up is expected to become effective, and the date as of which it
       is expected that holders of record of the shares of Common Stock shall be
       entitled to vote upon, and, if approved, to exchange their shares of
       Common Stock for securities or other property, if any, deliverable upon
       such reorganization, reclassification, consolidation, merger, conveyance,
       transfer, dissolution, liquidation or winding-up.

3.2.   If the event described in the notice given pursuant to Section 3.1. will
       result in an adjustment of the Conversion Price pursuant to Article 2,
       such notice shall also state the new Conversion Price unless the
       Conversion Price cannot be calculated at the time such notice is given.

3.3.   The failure to give or publish the notice required by this Article 3 or
       any defect therein shall not affect the legality or validity of the
       proceedings referred to in Section 3.1.

ARTICLE 4

So long as any of the Convertible Notes remain convertible, the Company shall
not take any action which would result in an adjustment of the Conversion Price
pursuant to Article 2 if, after giving effect thereto, the Conversion Price
would be decreased to such an extent that the Shares could not be legally
issued, under applicable law of the jurisdiction of incorporation of the Company
then in effect, at such decreased Conversion Price as fully-paid and
non-assessable Shares.

ARTICLE 5

The Conversion Agent shall not at any time be responsible to any Noteholder for
determining whether any facts exist (a) which may require any adjustment of the
Conversion Price, (b) with respect to the nature or extent of any such
adjustment when made, (c) with respect to the method employed, or herein or in
any supplemental agreement (if any) provided to be employed in making

<PAGE>

any such adjustment. The Conversion Agent makes no representation as to the
validity or value (or the kind or amount) of any shares of Common Stock, or
of any securities, property or cash, which may at any time be issued or
delivered upon the conversion of any Convertible Note. The Conversion Agent
shall not be responsible for any failure of the Company to make any cash
payment or to issue, transfer or deliver any shares of stock or stock
certificates or other securities or property upon the surrender of any Note
for the purpose of conversion or to comply with any of the covenants of the
Company contained in these Conversion Provisions.

ARTICLE 6

6.1.   In case of any consolidation of the Company with, or merger of the
       Company into, any other corporation (other than a consolidation or merger
       in which the Company is the continuing corporation), or in the case of
       any sale or transfer of all of the assets of the Company as an entirety
       or substantially as an entirety, the corporation formed by such
       consolidation or the corporation into which the Company shall have been
       merged or the corporation which shall have acquired such assets, as the
       case may be, shall execute with Banca del Gottardo a supplemental
       agreement which shall (a) provide that the holder of each Convertible
       Note then outstanding shall have the right to receive thereafter, during
       the period such Convertible Note shall be convertible as specified in
       Article 2, upon conversion of such Convertible Note, in lieu of each
       share of Common Stock deliverable on such conversion immediately prior to
       such event, only the kind and amount of shares and/or other securities
       and/or property and/or cash which are receivable, or which, but for the
       failure to distribute to holders of Common Stock all or substantially all
       of the consideration receivable on such sale or transfer of assets, would
       be receivable upon such consolidation, merger, sale or transfer by a
       holder of one share of Common Stock of the Company and (b) set forth the
       Conversion Price for the shares and/or other securities and/or property
       and/or cash so issuable, which shall be an amount equal to the Conversion
       Price per share of Common Stock of the Company immediately prior to such
       event.

6.2.   In case of any reclassification or change of the shares of Common Stock
       issuable upon conversion of the Notes (other than a change in par value,
       or from par value to no par value, or as a result of a subdivision or
       combination) 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 the holders of the shares of Common Stock
       thereafter receive shares, other securities, property, cash or any
       combination thereof for such shares of Common Stock (including for this
       purpose shares reflecting a change in par value or from par value to no
       par value or as a result of a subdivision or combination of the shares of
       Common Stock), the Company shall execute with Banca del Gottardo a
       supplemental agreement which shall (a) provide that the holder of each
       Convertible Note then outstanding shall receive, upon

<PAGE>

       conversion thereof, in lieu of each share of Common Stock of the
       Company deliverable upon such conversion immediately prior to such
       event, the kind and amount of shares and/or other securities and/or
       property and/or cash receivable upon such reclassification, change,
       consolidation or merger by a holder of one share of Common Stock, and
       (b) set forth the Conversion Price for the shares and/or other
       securities and/or property and/or cash so issuable, which shall be an
       amount equal to the Conversion Price per share of Common Stock
       immediately prior to such event.

6.3.   If, as a result of Section 6.1 or Section 6.2, the holder of any
       Convertible Note thereafter surrendered for conversion shall become
       entitled to receive shares of two or more classes of common stock of the
       Company, the Board of Directors (whose determination shall be conclusive)
       shall determine the allocation of the Conversion Price between or among
       shares of such classes of capital stock. Any supplemental agreement
       executed pursuant to Sections 6.1 and 6.2 shall provide for adjustments
       which shall be as nearly equivalent as practicable to the adjustments
       provided for herein, and, where appropriate, state the Conversion Price
       in terms of one full share of Common Stock or one full share of common
       stock of any successor or purchasing corporation. The terms of this
       Article 6 also shall apply to successive consolidations, merger, sales or
       transfers. In the event that at any time as a result of an adjustment
       made pursuant to this Article 6 the holder of any Note thereafter
       surrendered for conversion shall become entitled to receive any shares or
       securities other than shares of Common Stock, thereafter the prices or
       price of such other shares or other securities so receivable on
       conversion of any Convertible Note shall be subject to adjustment from
       time to time in a manner and on terms as nearly equivalent as practicable
       to the provisions with respect to Common Stock contained in Article 2,
       and the provisions of Article 2 with respect to the Common Stock shall
       apply on like terms to any such other shares.

6.4.   The Conversion Agent shall have no responsibility for any consolidation,
       merger, sale or transfer, the form or substance or any plan relating
       thereto or the consequences thereof to any Noteholder.

       The Conversion Agent shall have no responsibility to determine the
       correctness of any provision contained in any supplemental agreement
       relating either to the kind or amount of shares of stock or securities or
       property receivable by Noteholders upon the conversion of their
       Convertible Notes after any such consolidation, merger, sale or transfer,
       or to any adjustment made with respect thereto. The Conversion Agent may,
       at its option, receive an opinion of counsel for the Company as
       conclusive evidence that any such supplemental agreement complies with
       the provisions of this Article.

                                 PROMISSORY NOTE

$2,000,000.00                                                    July 26, 1999

         BIGMAR, INC. ("Borrower") promises to pay to CITIZENS BANK ("Lender"),
or order, in lawful money of the United States of America, on demand, the
principal amount of Two Million & 00/100 Dollars ($2,000,000.00) or so much as
may be outstanding, together with interest on the unpaid outstanding principal
balance of each advance. Interest shall be calculated from the date of each
advance until repayment of each advance.

         PAYMENT: Borrower will pay this loan immediately upon Lender's demand.
In addition, Borrower will pay regular monthly payments of all accrued unpaid
interest due as of each payment date, beginning August 28, 1999, with all
subsequent interest payments to be due on the same day of each month after that.
The annual interest rate for this Note is computed on a 365/360 basis; that is,
by applying the ratio of the annual interest rate over a year of 360 days,
multiplied by the outstanding principal balance, multiplied by the actual number
of days the principal balance is outstanding. Borrower will pay Lender at
Lender's address shown above or at such other place as Lender may designate in
writing. Unless otherwise agreed or required by applicable law, payments will be
applied first to accrued unpaid interest, then to principal, and any remaining
amount to any unpaid collection costs and late charges.

         VARIABLE INTEREST RATE: The Interest rate on this Note is subject to
change from time to time based on changes in an index which is Lender's Prime
Rate (the "Index"). This is the rate Lender charges, or would charge, on 90-day
unsecured loans to the most creditworthy corporate customers. This rate may or
may not be the lowest rate available from Lender at any given time. Lender will
tell Borrower the current index rate upon Borrower's request. Borrower
understands that Lender may make loans based o n other rates as well. The
interest rate change will not occur more often than each day. THE INDEX
CURRENTLY IS 8.250% PER ANNUM. THE INTEREST RATE TO BE APPLIED TO THE UNPAID
PRINCIPAL BALANCE OF THIS NOTE WILL BE AT A RATE EQUAL TO THE INDEX, RESULTING
IN AN INITIAL RATE OF 8.250% PER ANNUM. NOTICE: Under no circumstances will the
interest rate on this Note be more than the maximum rate allowed by applicable
law.

         PREPAYMENT: Borrower may pay without penalty all or a portion of the
amount owed earlier than it is due. Early payments will not, unless agreed to by
Lender in writing, relieve Borrower of Borrower's obligation to continue to make
payments of accrued unpaid interest. Rather, they will reduce the principal
balance due.

         LATE CHARGE: If a regularly scheduled interest payment is 10 DAYS OR
MORE LATE, Borrower will be charged 5.000% OF THE UNPAID PORTION OF THE
REGULARLY SCHEDULED PAYMENT OR $25.00, WHICHEVER IS GREATER. If Lender demands
payment of this loan, and Borrower does not pay the loan WITHIN 10 DAYS AFTER
LENDER'S DEMAND, BORROWER ALSO WILL BE CHARGED EITHER 5.000% OF THE UNPAID
PORTION OF THE SUM OF THE UNPAID PRINCIPAL PLUS ACCRUED UNPAID INTEREST OR
$25.00, WHICHEVER IS GREATER.

         DEFAULT: Borrower will be in default if any of the following happens:
(a) Borrower fails to make any payment when due. (b) Borrower breaks any promise
Borrower has made to Lender, or Borrower fails to comply with or to perform when
due any other term, obligation, covenant, or condition contained in this Note or
any agreement related to this Note, or in any other agreement or loan Borrower
has with Lender. (c) Borrower defaults under any loan, extension of credit,
security agreement, purchase or sales agreement, or any other agreement, in
favor of any other creditor or person that may materially


<PAGE>


affect any of Borrower's property or Borrower's ability to repay this Note or
perform Borrower's obligations under this Note or any of the Related
Documents. (d) Any representation or statement made or furnished to Lender by
Borrower or on Borrower's behalf is false or misleading in any material
respect either now or at the time made or furnished. (e) Borrower becomes
insolvent, a receiver is appointed for any part of Borrower's property,
Borrower makes an assignment for the benefit of creditors, or any proceeding
is commenced either by Borrower or against Borrower under any bankruptcy or
insolvency laws. (f) Any creditor tries to take any of Borrower's property on
or in which Lender has a lien or security interest. This includes a
garnishment of any of Borrower's accounts with Lender. (g) Any guarantor dies
or any of the other events described in this default section occurs with
respect to any guarantor of this Note. (h) A material adverse change occurs
in Borrower's financial condition, or Lender believes the prospect of payment
or performance of the indebtedness is impaired. (i) Lender in good faith
deems itself insecure.

         In any default, other than a default in payment, is curable and if
Borrower has not been given a notice of a breach of the same provision of this
Note within the preceding twelve (12) months, it may be cured (and no event of
default will have occurred) if Borrower, after receiving written notice from
Lender demanding cure of such default: (a) cures the default within ten (10)
days; or (b) if the cure requires more than ten (10) days, immediately initiates
steps which Lender deems in Lender's sole discretion to be sufficient to cure
the default and thereafter continues and completes all reasonable and necessary
steps sufficient to produce compliance as soon as reasonably practical.

         LENDER'S RIGHTS: Upon default, Lender may declare the entire unpaid
principal balance on this Note and all accrued unpaid interest immediately due,
without notice, and then Borrower will pay that amount. Upon default, including
failure to pay upon final maturity, Lender, at its option, may also, if
permitted under applicable law, increase the variable interest rate on this Note
to 4.000 percentage points over the index. The interest rate will not exceed the
maximum rate permitted by applicable law. Lender may hire or pay someone else to
help collect this Note if Borrower does not pay. Borrower also will pay Lender
that amount. This includes, subject to any limits under applicable law, Lender's
reasonable attorneys' fees and Lender's legal expenses whether or not there is a
lawsuit, including reasonable attorneys' fees and legal expenses for bankruptcy
proceedings (including efforts to modify or vacate any automatic stay or
injunction), appeals, and any anticipated post-judgment collection services. If
not prohibited by applicable law, Borrower also will pay any court costs. In
addition to all other sums provided by law. THIS NOTE HAS BEEN DELIVERED TO
LENDER AND ACCEPTED BY LENDER IN THE STATE OF MICHIGAN. IF THERE IS A LAWSUIT,
BORROWER AGREES UPON LENDER'S REQUEST TO SUBMIT TO THE JURISDICTION OF THE
COURTS OF GENESEE COUNTY, THE STATE OF MICHIGAN. THIS NOTE SHALL BE GOVERNED BY
AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF MICHIGAN.

         RIGHT OF SETOFF: Borrower grants to lender a contractual security
interest in, and hereby assigns, conveys, delivers, pledges, and transfers to
Lender all Borrower's right, title and interest in and to, Borrower's accounts
with Lender (whether checking, savings, or some other account), including
without limitation all accounts held jointly with someone else and all accounts
Borrower may open in the future, excluding however all IRA and Keogh accounts,
and all trust accounts for which the grant of a security interest would be
prohibited by law. Borrower authorizes Lender, to the extent permitted by
applicable law, to charge or setoff all sums owing on this Note against any and
all such accounts.

INVENTORY, CHATTEL PAPER, ACCOUNTS RECEIVABLE, GENERAL INTANGIBLES & EQUIPMENT;
