5.   Earnings Per Share

The Company has adopted Statement of Financial Accounting Standards 128 ("SFAS
128"), "Earnings Per Share" which replaced the calculation of primary and fully
diluted earnings per share with basic and diluted earnings per share. Basic
earnings per share is computed by dividing net income by the weighted average
number of common shares outstanding during the period. Diluted earnings per
share is computed by dividing net income by the weighted average number of
common shares and common stock equivalents outstanding during the period. Common
stock equivalents of the Company include the dilutive effect of outstanding
stock options.

     Basic and Diluted earnings per share were calculated as follows:

6.   Orders for Future Delivery

At February 29, 2000 and February 28, 1999 the Company had orders for future
delivery of $1,440,454 and $1,138,821. The $1,440,454 orders for future delivery
are scheduled for shipment during the period March, 2000 through July, 2000.
Data for both years excludes expected sales of Sanova to the poultry industry
because contracts with Sanova customers do not require placement of purchase
orders for future delivery. Sanova sales are based on product usage reported by
the customers after the fact. The thirteen customers using the System on
February 29, 2000 purchase roughly $382,000 per month.

                                          ==========   ==========   ==========   ==========
</TABLE>

The Company's animal health and surface disinfectant sales are lower than last
year for both the quarter and nine month periods as a result of lower sales to
distributors in both the domestic U.S. market and international markets where
the Company's products are sold. The decrease in sales to distributors was
caused by a number of factors, including an economic recession in the dairy
industry, a reduction in the amount of Alcide's inventory carried by the
Company's distributors, increased competition in the marketplace and delays in
the transfer and reassignment of international registrations for the Company's
products from its former distributor, ABS Global, Inc., which delays temporarily
blocked the Company from selling its products in certain international markets.

During the nine month period of last year the Company received $1,136,703 as a
contractually required payment from Novus International, Inc. The contract with
Novus ended in November, 1998 and subsequently Alcide has acted on its own
behalf in sales to the poultry industry. At the start of the third quarter,
eleven poultry processing


                                       9

plants were utilizing the Sanova Food Quality System for pathogen control.
Thirteen plants were using the System at the end of the quarter.

Cost of goods as a percentage of net sales was 57% for the quarter ended
February 29, 2000, as compared to 47% for the corresponding quarter last year.
Cost of goods as a percentage of net sales was 61% for the nine month period
ended February 29, 2000 vs. 39% for the first nine months of last year. The
year-to-year differences in cost of goods as a percentage of net sales were
caused primarily by the loss of the contractual minimum payment from Novus and
by startup and maintenance costs associated with direct distribution of Sanova
to the poultry industry.

Royalty expenses for the third quarter and nine month periods last year totaled
$2,262,046 and $2,412,994 respectively and reflect a one-time $2,262,044 charge
to royalty expense during the third quarter last year to settle a lawsuit with
royalty rights holders. The payment and settlement of the suit eliminated the
Company's obligation to pay royalties from that point forward and, accordingly,
no royalty expense occurred during the present fiscal year.

Research and development expenses for the three months ended February 29, 2000
were $349,484, $111,049 lower than the corresponding period last year. Research
and development expenses for the first nine months of fiscal 2000 were
$1,284,442, $335,141 lower than the first nine months last year. During the nine
month period last year the Company paid Novus International, Inc. $317,000,
related to research and development, as part of a negotiated settlement when the
contract with Novus ended.

Other selling, general and administrative expenses for the third quarter of
fiscal 2000 increased to $1,004,889 from $804,245 in the third quarter of fiscal
1999. Other selling, general and administrative expenses for the first nine
months of fiscal 2000 increased to $3,114,427 from $2,200,063 during the first
nine months last year. The increase in expenses for both the third quarter and
first nine months was due primarily to expenses totaling $473,761 for the
quarter and $1,348,214 for the first nine months incurred to manage Sanova
projects.

Interest income of $60,372 for the third quarter and $201,742 for the first nine
months of fiscal 2000 was down from the $123,916 and $444,129 for the
corresponding periods last year because the Company's investable cash resources
have decreased.

LIQUIDITY AND CAPITAL RESOURCES

The Company's cash, cash equivalents, short term investments and U.S. Treasury
investments totaled $3,669,937 on February 29, 2000, an amount $3,225,189 lower
than at the end of the previous fiscal year. The reduction is due primarily to
an investment of $3,772,653 in new Sanova installations offset by a $457,992
reduction in inventory.

Alcide has negotiated a $10 million line of credit from U.S. Bank as a backup
source of capital, if needed, to support Alcide's growing food safety business.
The Company has not drawn on the credit line.

During the three month period ended February 29, 2000 the Company purchased
9,938 shares of Alcide Common stock for $129,567. Also, during the quarter,
6,451 shares of Treasury stock were transferred to Alcide's Employee Stock
Ownership Plan.

YEAR 2000 ISSUES

The Company has experienced no adverse financial or operational impact resulting
from year 2000 computer associated problems. All of the Company's computer
systems, including those which control the Sanova poultry plant installations,
passed into calendar year 2000 without incident.

OUTLOOK

-    Sanova Food Quality System

     The size of the Company's food antimicrobial business is expanding. At the
     end of fiscal 1999, five poultry plants were utilizing the Sanova Food
     Quality System. At March 31, 2000, sixteen plants, having an annual
     capacity of 740 million birds, 9% of the U.S. market, were using the Sanova
     System. The sixteen plants are expected to generate annual sales of
     approximately $6.1 million. The Company has announced a goal to increase to
     twenty plants using the System by the end of fiscal 2000. Each new plant
     will require an Alcide capital investment of $300,000 to $400,000.

     During the nine month period the Company expended $1.5 million for
     maintenance, engineering, research and development to support expansion of
     the Company's food safety business. These expenditures had a direct
     negative impact on the Company's pre-tax income for the quarter and nine
     month periods, but are intended to lead to improved future financial
     performance and expansion of the food safety business. The Company has
     identified a number of programs to reduce Sanova cost of goods while
     maintaining the present high level antimicrobial performance. Such programs
     have been implemented concurrent with the most recent six installations and
     are in the process of being retrofitted into the initial ten
     installations..

-    Animal Health Products

     The Company's distribution agreements with ABS Global, Inc. expired on
     October 31, 1998 and were not renewed. Effective November 1, 1998 Alcide
     entered into a new four year agreement with IBA, Inc. to expand IBA's
     territory to cover the entire United States. In addition, the present
     Universal Marketing Services, Inc. contract has been amended to include the
     additional territories of Canada, Italy, Portugal and the Czech Republic as
     exclusive UMS territories and the United States as a non-exclusive
     territory.

     In November, 1998, ABS Global, Inc. began distributing an udder care
     product which competes with Alcide's udder care products. Subsequently, at
     least one other national distributor has introduced a product similar to
     Alcide's UDDERgold technology. The transition from ABS to two new expanded
     distributors, IBA and UMS, coupled with new competing technology, may have
     an impact on future Alcide sales in the U.S. market.

     Recently ABS introduced its new line of udder care products in both the
     United Kingdom and Italian markets. The degree to which these new products
     will impact Alcide's udder care sales cannot be determined at this time.
