                          BIGMAR, INC. AND SUBSIDIARIES

              NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS

(1) BASIS OF PRESENTATION

Bigmar, Inc. is a Delaware Corporation that owns 100% of the capital stock of 
two Swiss Corporations, Bioren, SA and Bigmar Pharmaceuticals, SA, and 100% 
of the capital stock 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 March 31, 1999 and 1998, and the results of operations and the 
cash flows and the comprehensive income for all periods presented. Certain 
amounts in the accompanying financial statements have been restated to 
conform to the March 31, 1999 presentation. The results of the interim 
periods are not necessarily indicative of the results to be obtained for the 
entire 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 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 $1,760,000 in proceeds from the private placements of common stock. 
In addition, the Company anticipates raising additional funds during 1999 
through other private stock offerings and through additional bank borrowings. 
However, there can be no assurance that the Company will be successful in 
these efforts. These factors raise substantial doubt about the Company's 
ability to continue as a going concern. 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.

(3) 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 was 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 totaled $750,000 and was applied to working 
capital and general corporate purposes.

In April 1999, the Company issued 103,333 shares of common stock to 
accredited investors for $3.00 per share via private placements, with the 
proceeds applied to working capital and general corporate purposes.

(4) RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

In June 1998, Statement of Financial Accounting Standards No. 133 ("SFAS No. 
133"), "Accounting for Derivative Instruments and Hedging Activities" was 
issued. This statement revises the accounting for derivative financial 
instruments. The Company has analyzed the impacts of this statement which is 
required to be adopted in the year ending December 31, 2000, and does not 
expect this statement to have a material impact on the Company's financial 
position nor results of operations. As of and for the three months ended 
March 31, 1999, the Company was not engaged in hedge or forward exchange 
contracts.

In April 1998, the American Institute of Certified Public Accountants 
("AICPA") issued Statement of Position 98-5 ("SOP 98-5"), "Reporting on the 
Costs of Start-up Activities", which revises the accounting for start-up 
costs and requires the expensing of certain costs which the Company has 
historically capitalized. The adoption of this statement in the year ending 
December 31, 1999 had an immaterial impact on the Company's financial 
position and results of operations.

(5) 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 as of and for the quarters ended March 31, 
1999 and March 31, 1998 is as follows:

                          BIGMAR, INC. AND SUBSIDIARIES

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


Bigmar, Inc. (the "Company") was incorporated in Delaware in September 1995 
and has three wholly-owned subsidiaries--Bioren SA ("Bioren"), Bigmar 
Pharmaceuticals SA ("Pharmaceuticals"), and Bigmar Therapeutics 
("Therapeutics"). Bioren is a Swiss corporation formed in July 1986. 
Pharmaceuticals is a Swiss corporation that was formed in January 1992 under 
the name BVI, SA. Therapeutics is a Delaware corporation formed in September 
1995 under the name Bioren, Inc.; the name was changed in November 1995.

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, includes a research and development laboratory used for the 
testing of generic oncology and related products ("Oncology Products") to be 
marketed in the U.S.

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 calcium 
leucovorin, methotrexate, and cisplatin. The Oncology Products are currently 
marketed in Germany and Spain. Pharmaceuticals' primary strategy is to supply 
world markets with a full line 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
Therapeutics is essentially a shell company and has had no significant 
business operations as of December 31, 1998.

Certain statements under this caption constitute "forward-looking statements" 
within the meaning of the Private Securities Litigation Reform Act of 1995 
including, without limitation, statements regarding future cash requirements. 
Such forward-looking statements involve known and unknown risks, 
uncertainties, and other factors which may cause the actual results, 
performance or achievements of the Company, or industry results, to be 
materially different from any future results, performance or achievements 
expressed or implied in such forward-looking statements. Examples of these 
risks include: delays in product development, problems with clinical testing, 
failure to receive regulatory approvals, lack of proprietary rights, or 
changes in business strategy.

RESULTS OF OPERATIONS

First quarter 1999 net sales amounted to approximately $1.7 million, 
representing a increase of $299,000 or 21% over first quarter 1998 sales. 
This increase was primarily the result of sales to new customers in the first 
quarter of 1999.

Sales at Bioren SA increased by 18% over first quarter 1998 sales from 
$1,331,000 to $1,574,000. Sales levels were maintained for existing customers 
and two new customers were added in the first quarter of 1999.

Sales at Pharmaceuticals remained comparable with first quarter of 1998. Sales 
were $162,000 in 1999 and were $105,000 in 1998.

Cost of goods sold increased by $164,000 from the three months ended March 
31, 1998 to the same period in 1999. The increase can be attributed to the 
increase in cost of raw materials at Bioren.

Pharmaceuticals cost of goods sold was materially comparable with the first 
quarter of 1998 with sales of $45,000 in 1999 and $81,000 respectively.

Gross margin amounted to $493,000 for the first quarter of 1999, compared 
with $358,000 from the prior year. Gross margin percent amounted to 
approximately 28% for the first quarter of 1999, compared to approximately 
25% for the prior year. The increase in the gross margin percent was due to 
improved sales for the facilities.

Operating expenses decreased from first quarter 1998 to first quarter 1999, 
by $270,000. Research and development expenses decreased by $109,000, due to 
personnel costs and activities surrounding the Company's efforts in the prior 
year to prepare for the February 1999 inspection of its Swiss manufacturing 
facility by the FDA and development of new drug product formulations. 
Selling, general and administrative expenses decreased by $161,000, primarily 
due to a decrease in the number of personnel from first quarter 1998 to first 
quarter 1999.

                                     11

<PAGE>

Interest expense decreased $49,000 from 1998 to 1999, due to reduction of 
total debt by $350,000 in the first quarter of 1999 as compared to the first 
quarter of 1998.

Foreign exchange losses amounted to $402,000 in the first quarter of this 
year compared to $281,000 in the prior year. The expense represents losses 
due to exchange rate fluctuations on certain intercompany accounts receivable 
denominated in Swiss francs.

As a result of all of the foregoing, the Company's net loss for the first 
quarter 1999 amounted to $1.8 million versus $2.1 million during the first 
quarter of 1998.

Net loss at Bioren SA improved from a net loss of $198,623 in the first 
quarter of 1998 to a net loss of $26,324 in the first quarter of 1999 due to 
improved sales and cost efficiencies.

Net loss at Pharmaceuticals improved from a net loss of $914,012 in the first 
quarter of 1998 to a net loss of $401,871 in the first quarter of 1999 due to 
improved sales and cost efficiencies.

The net loss at Corporate increased from a net loss of $1,002,668 in the 
first quarter of 1998 to a net loss of $1,346,861 in the first quarter of 
1999 due to additional expenses incurred to gain certain regulatory approvals.


LIQUIDITY AND CAPITAL RESOURCES

As of March 31, 1999 and December 31, 1998, the Company had cash and cash 
equivalents of $0 and $0.1 million, respectively. The Company's working 
capital was a ($1.9) million deficit and ($3.1) million deficit at March 31, 
1999 and December 31, 1998, respectively.

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 and the number of new products the 
Company plans to add during the year. The regulatory bodies may require more 
testing than is currently planned by the Company. There can be no assurance 
that the Company's generic oncological products will be approved for 
marketing by the FDA or any foreign government agency, or that any such 
products will be successfully introduced or achieve market acceptance.

Property, plant and equipment totaled $16.2 million and $17.4 million at 
March 31, 1999 and at December 31, 1998, respectively. Additions of 
approximately $125,000 were offset by depreciation expense ($161,000) and 
foreign currency translation effects ($1,164,000).

                                     12

<PAGE>

As of March 31, 1999, the Company had various notes, bonds, mortgages and 
other borrowings totaling approximately $10.4 million including $477,000 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 of 1999, the Company renegotiated two 
of its debt agreements whereby the maturities of approximately $800,000 were 
extended to 2000, and beyond.

During the first four months of 1999, pursuant to private placement transactions
with accredited investors, the Company raised $1,760,000 which 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 open 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.

YEAR 2000 COMPLIANCE

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 problems arising 
out of this inability are commonly referred to as the "Year 2000 Issue" 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 

                                     13

<PAGE>

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 
March 31, 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. Although these Programs 
and Systems do not yet comply with Year 2000 requirements, an assessment has 
been made and it has been determined that, based on present information, the 
Company believes that these Programs and Systems will be upgraded by June 30, 
1999, and the costs to bring them into compliance will be less than $10,000. 
However, there can be no assurance that the required expenditures will not 
exceed that amount.

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 THE 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 mid 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.

                                ABOUT MARKET RISK

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. At this time, 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. At this time, 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.

instruments by functional currency and presents such information in U.S. 
dollar equivalents:

PART II. OTHER INFORMATION

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

In February 1999, in private placement transactions exempt from registration 
pursuant to Section 4(2) of the Securities Act of 1933 and Rule 506 of 
Regulation D, the Company issued 236,666 shares of common stock to accredited 
investors for prices ranging from $2.00 to $3.00 per share.

In March 1999, in private placement transactions pursuant to Section 4(2) and 
Rule 506, the Company issued 250,000 shares of common stock to accredited 
investors for $3.00 per share.

In April 1999, in private placement transactions pursuant to Section 4(2) and 
Rule 506, the Company issued 103,333 shares of common stock to accredited 
investors 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 11933, 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.
