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 August 31, 1999 and 1998 the Company had orders for future delivery of
$1,396,872 and $2,350,050 respectively. The reduction in orders for future
delivery at August 31, 1999, as compared to August 31, 1998, is due primarily to
the change in order terms in the Company's distributor agreements. The present
agreements require a 45 day lead time. The agreements last year required that
orders be placed 90 days in advance of expected delivery. The $1,396,872 orders
for future delivery are scheduled for shipment during the period September, 1999
through November, 1999.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS

INTRODUCTION

Alcide Corporation (the "Company") is a Delaware Corporation organized in 1983
which has its executive offices and research laboratories at 8561 154th Avenue
N.E., Redmond, Washington 98052.

Alcide is engaged in the research, development and commercialization of unique
chemical compounds having intense microbiocidal activity. The Company holds
substantial worldwide rights to its discoveries through various patents, patent
applications, trademarks and other intellectual property, technology, and
know-how.

This report includes forward-looking statements which involve risk and
uncertainty including, without limitation, risk of dependence on patents and
trademarks, third party suppliers, market acceptance of and demand for the
Company's products, distribution capabilities, development of technology and
regulatory approval thereof. Sentences or phrases that use the words such as
"believes," "anticipates," "hopes," "plans," "may," "can," "will," "expects,"
and others, are often used to flag such forward-looking statements, but their
absence does not mean a statement is not forward-looking. Such statements
reflect management's current opinion and are designed to help readers understand
management's thinking. By their very nature, however, such statements are
subject to certain risks and uncertainties that could cause actual results to
differ materially from those projected. Readers are cautioned not to place undue
reliance on these forward-looking statements which speak only as of the date
hereof. The Company undertakes no obligation to release publicly any revisions
to these forward-looking statements that may be made to reflect events or
circumstances after the date hereof, or to reflect the occurrence of
unanticipated events.

FINANCIAL CONDITION AND RESULTS OF OPERATIONS
Net sales for the three month period ended August 31, 1999 were $2,674,398,
$1,106,881 lower than the equivalent three month period last year, which
included revenue from Novus International, Inc. of $1,154,988 related to a
contractual minimum payment.

The net loss of $394,324 is a reversal from the net income of $1,033,738 for the
three month period ended August 31, 1998, reflecting the negative impact of
several events which occurred during the three month periods, including:

-    The contractual minimum payment of $1,154,988 from the Company's former
     distributor, Novus International, Inc. in fiscal 1999. This payment
     contributed $636,000 to net income for the first quarter last year. The
     agreement with Novus ended November 30, 1998, and the payment for the
     quarter ended August 31, 1998 was the final payment received from Novus.

-    First quarter FY 2000 expenses totaling $544,160 for maintenance,
     engineering and research and development to support the expansion of the
     Company's food safety business within the poultry industry. These
     expenditures contributed approximately $359,150 to the loss for the
     quarter, but are intended to lead to improved future financial performance
     and expansion of the Company's food safety business.

                                        9

<PAGE>

-    A decrease of $621,010 in sales of the Company's animal health products to
     international markets formerly covered by distribution arrangements with
     ABS Global. The ABS agreements terminated October 31, 1998. Establishment
     of new distribution has been delayed by depletion of ABS and ABS
     sub-distributor inventories of Alcide product and by delays in transferring
     local product registration.

Cost of goods as a percentage of net sales was 63% for the three month period
ended August 31, 1999, an increase of 34 points over the 29% of net sales for
the same period last year. Sanova cost of goods during the quarter with no
corresponding minimum profit as occurred in the prior year accounted for 80% of
the difference. The balance of the increase is due primarily to a difference in
product mix.

Royalty expenses for the first quarter last year totaled $84,216. As a result of
the May, 1999 settlement of the royalty rights holders' lawsuit against the
Company, the Company's obligation to pay royalties ended.

Research and development expenses of $442,444 for the three month period ended
August 31, 1999 were $104,363 higher than for the first three months last year.
This increase is primarily due to testing to support Sanova cost reduction
programs and validation trials in commercial plants.

Other selling, general and administrative expenses of $1,172,612 for the three
months ended August 31, 1999 were $428,099 higher than for the equivalent period
last year. The increase reflects costs incurred to manage the Sanova projects
following termination of the Novus agreement of approximately $456,765.

Interest income of $78,000 for the three month period ended August 31, 1999 was
$93,517 lower than the equivalent three month period last year primarily because
the Company's investable cash resources were roughly 46% lower during the most
recent quarter as compared to the equivalent period a year ago.

LIQUIDITY AND CAPITAL RESOURCES
The Company's cash, cash equivalents, short term investments and U.S. Treasury
investments totaled $5,238,629 on August 31, 1999, an amount $1,656,497 lower
than at the end of the previous fiscal year. The reduction is due primarily to
an investment of $1,788,762 in new Sanova installations.

During the quarter the Company negotiated a $10 million unrestricted line of
credit from US Bank as a backup source of capital, if needed, to support
Alcide's growing food safety business. As of August 31, 1999 the Company had not
drawn on the credit line.

YEAR 2000 ISSUES
The Company has developed and is implementing a comprehensive plan to address
issues related to Year 2000. The organizational simplicity of Alcide's business
structure, which relies heavily on third party manufacturers and a network of
third party distributors, limits the direct financial impact on the Company to
become Year 2000 compliant.

It has been necessary to upgrade the Company's accounting software which
controls internal and external reporting, sales order and billing records, cost
accounting inventory records, accounts

                                        10

<PAGE>

payable and cash management processes. The costs incurred to accomplish the
upgrade were approximately $10,000 and were recorded as an expense during
fiscal 1998. All such upgrades have been completed.

Further, the Company identified a need to upgrade computer software which
controls certain laboratory analytical instruments. The upgrade was completed
during the Company's fiscal 1999 third quarter at a cost of $12,297.

Lastly, the Company has surveyed each of its raw material suppliers,
manufacturing resources and distributors to assure their Year 2000 readiness.

All business related computer systems are fully Year 2000 compatible. Critical
raw materials and manufacturing requirements are available from multiple sources
and the Company can serve its distributors without reliance on computers.

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 September 30, 1999, eleven plants, having an annual
     capacity of 450 million birds, 6% of the U.S. market, were using the Sanova
     System. The eleven plants are expected to generate annual sales of
     approximately $3.7 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.

     Investments in research, development and engineering during the fiscal
     first quarter to optimize the Sanova System and formulation will continue,
     but at a decreased rate, during the Company's second quarter. The Company
     has identified a number of programs to reduce Sanova cost while maintaining
     the present high level antimicrobial performance. These cost reduction
     programs will be transitioned into existing Sanova installations during the
     second quarter.

-    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.

     Management believes that the combined distribution coverage provided by IBA
     and UMS has the potential to equal or surpass that previously provided by
     ABS for the territories of the United States, Canada, Italy, Portugal and
     the Czech Republic.

     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

                                        11

<PAGE>

     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.

ITEM 3.  LEGAL PROCEEDINGS:

ALCIDE PATENT INFRINGEMENT LAWSUIT AGAINST ABS GLOBAL, INC. IN THE U.S.:
On October 6, 1999, Judge Barbara Crabb granted defendant's motion for summary
judgement of non-infringement of Claim 1 of Alcide's '531 patent under the
doctrine of equivalents. The court concluded that ABS's Valiant Barrier Teat Dip
does not infringe Claim 1 of Alcide's patent, and if Claim 1 is not infringed,
no other claim is infringed, since all other claims are dependent on Claim 1.

Alcide's attorneys believe that the court's opinion contains a number of errors
with respect to the chemistry and composition of the ABS product. Accordingly,
the attorneys recommend appealing the court's decision to the Federal Circuit
Court. It is likely that Alcide will decide to file the appeal as recommended.

ALCIDE'S PATENT INFRINGEMENT LAWSUIT AGAINST ABS GLOBAL, INC. IN THE UNITED
KINGDOM:
During September, 1999, Alcide became aware that ABS was in the process of
introducing its Valiant teat dip in the United Kingdom, where Alcide believes
the Valiant product infringes its patent. On October 1, 1999, Alcide filed a
patent infringement suit against ABS in the UK. As of this date there has been
no court action on Alcide's lawsuit.
