<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;As permitted by Section&nbsp;145 of the Delaware General Corporation Law, Article&nbsp;10 of the Registrant's Amended Certificate of Incorporation (the
"Certificate") eliminates a director's personal liability for monetary damages to the Registrant and its stockholders arising from a breach or alleged breach of a director's fiduciary duty except for
liability under Section&nbsp;174 of the Delaware General Corporation Law or liability for any breach of the director's duty of loyalty to the Registrant or its stockholders, for acts or omissions
not in good faith or which involve intentional misconduct or a knowing violation of law or for any transaction from which the director derived an improper personal benefit. The effect of this
provision in the Certificate is to eliminate the rights of the Registrant and its stockholders (through stockholder's derivative suits on behalf of the Registrant) to recover monetary damages against
a director (including breaches resulting from negligent or grossly negligent behavior) except in the situations described above. </FONT></P>

connection with actions in which the Indemnitee is involved by reason of having been a director or employee of the Registrant. </FONT></P>

information in this Registration Statement; </FONT></P>

</UL>

<P><FONT SIZE=2><I>provided, however, </I></FONT><FONT SIZE=2>that paragraphs (1)(i)&nbsp;and (1)(ii)&nbsp;above do not apply if the information required to be included in a

as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing
provisions, or otherwise, the Registrant has been advised that in the opinion of the Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore,
unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered,
the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification
by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue. </FONT></P>

Form S-8
Registration Statement filed with the Securities and Exchange Commission on February 13, 1996 (File No. 333-00909) for the
Registrant's 1993 Stock Option Plan has been post-effectively amended to provide that up to 50,000 shares of the Registrant's common stock previously authorized for issuance under the
Registrant's 1993 Stock Option Plan may now be issued under the Registrant's 2001 Stock Incentive Plan, provided such shares (a) were not issued or subject to outstanding options under the 1993
Stock Option Plan as of July 19, 2001, the date the Registrant's Board of Directors approved the 2001 Stock Incentive Plan or (b) are shares subject to outstanding options as of
July 19, 2001 that subsequently cease to be subject to such options (other than by reason of exercise of the options). No additional stock options will be granted under the Registrant's 1993
Stock Option Plan.

NASDAQ National Market.
PART II
INFORMATION REQUIRED IN REGISTRATION STATEMENT
Item 3. INCORPORATION OF CERTAIN DOCUMENTS BY REFERENCE
The following documents filed with the Securities and Exchange Commission (the "Commission") by the registrant, Alcide Corporation, a Delaware Corporation (the
"Registrant"), are hereby incorporated by reference in this Registration Statement:
(a)  The
Registrant's Annual Report on Form 10-K for the year ended May 31, 2001, filed on August 16, 2001, which contains audited financial
statements for the most recent fiscal year for which such statements have been filed;
(b)  The
Registrant's Quarterly Reports on Form 10-Q for the fiscal quarters ended August 31, 2001, November 30, 2001 and February 28,
2002 filed on October 12, 2001, January 14, 2002, and April 9, 2002, respectively;
(c)  The
description of the Registrant's Common Stock contained in the Registration Statement on Form 8-A, filed with the Commission on August 8,
1983, under Section 12(g) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), including any amendments or reports filed for the purpose of updating such description; and
(d)  All
other reports filed pursuant to Section 13(a) or 15(d) of the Exchange Act since the end of the fiscal year covered by the Annual Report on
Form 10-K referred to in (a) above.
All
documents filed by the Registrant pursuant to Sections 13(a), 13(c), 14 and 15(d) of the Exchange Act after the date hereof, and prior to the filing of a post-effective
amendment which indicates that the securities offered hereby have been sold or which deregisters the securities covered hereby then remaining unsold, shall also be deemed to be incorporated by
reference into this Registration Statement and to be a part hereof commencing on the respective dates on which such documents are filed.
Item 4. DESCRIPTION OF SECURITIES
Not applicable.
Item 5. INTERESTS OF NAMED EXPERTS AND COUNSEL
Not applicable.
Item 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS
As permitted by Section 145 of the Delaware General Corporation Law, Article 10 of the Registrant's Amended Certificate of Incorporation (the
"Certificate") eliminates a director's personal liability for monetary damages to the Registrant and its stockholders arising from a breach or alleged breach of a director's fiduciary duty except for
liability under Section 174 of the Delaware General Corporation Law or liability for any breach of the director's duty of loyalty to the Registrant or its stockholders, for acts or omissions
not in good faith or which involve intentional misconduct or a knowing violation of law or for any transaction from which the director derived an improper personal benefit. The effect of this
provision in the Certificate is to eliminate the rights of the Registrant and its stockholders (through stockholder's derivative suits on behalf of the Registrant) to recover monetary damages against
a director (including breaches resulting from negligent or grossly negligent behavior) except in the situations described above.
Section 7
of Article VII of the Registrant's By-Laws (the "By-Laws") provides for the indemnification of officers, directors and employees. In
addition, the Company has entered into an
II-1
indemnification agreement ("Indemnification Agreement") with each officer and director of the Registrant (each an "Indemnitee"). Under Section 7 of Article VII of the
By-Laws and these Indemnification Agreements, the Registrant has agreed to indemnify an Indemnitee to the fullest extent permitted by Delaware law for losses and expenses incurred in
connection with actions in which the Indemnitee is involved by reason of having been a director or employee of the Registrant.
The
Registrant also maintains an insurance policy insuring its directors and officers against liability for certain acts and omissions while acting in their official capacities.

Item 9. UNDERTAKINGS
A.    The
undersigned Registrant hereby undertakes:
(1)  To
file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement:
(i)  To
include any prospectus required by Section 10(a)(3) of the Securities Act of 1933, as amended (the "Securities Act");
(ii)  To
reflect in the prospectus any facts or events arising after the effective date of this Registration Statement (or the most recent post-effective
amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in this Registration Statement; and
(iii)  To
include any material information with respect to the plan of distribution not previously disclosed in this Registration Statement or any material change to such
information in this Registration Statement;
provided, however,
that paragraphs (1)(i) and (1)(ii) above do not apply if the information required to be included in a
post-effective amendment by those paragraphs is contained in periodic reports filed by the Registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are
incorporated by reference in this Registration Statement.
(2)  That,
for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration
statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
II-2
(3)  To
remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the
offering.
B.    The
undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the registrant's annual report pursuant to
Section 13(a) or 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefits plan's annual report pursuant to Section 15(d) of the Exchange Act) that is
incorporated by reference in this Registration Statement
shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering
thereof.
C.    Insofar
as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing
provisions, or otherwise, the Registrant has been advised that in the opinion of the Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore,
unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered,
the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification
by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.
II-3
SIGNATURES
Pursuant to the requirements of the Securities Act of 1933, the Registrant certifies that it has reasonable grounds to believe that it meets all the requirements
for filing on Form S-8 and has duly caused this Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of Redmond, State of
