                           INFORMATION REQUIRED IN THE
                             REGISTRATION STATEMENT

Item 3. INCORPORATION OF CERTAIN DOCUMENTS BY REFERENCE

     The following documents, filed with the Securities and Exchange Commission
(the "Commission") by Hauser, Inc., a Delaware corporation (the "Company"), are
incorporated by reference into the Registration Statement:

     (a) The Company's Annual Report on Form 10-K (File No. 0-17174) for the
     fiscal year ending April 30, 1999, as amended by the amendment on Form
     10-K/A, filed on October 27, 1999 pursuant to the Securities Exchange Act
     of 1934, as amended (the "Exchange Act");

     (b) The Company's Quarterly Reports on Form 10-Q for the quarters ended
     July 31, 1999, October 31, 1999 and January 31, 2000, filed pursuant to the
     Exchange Act;

     (c) The Company's Current Reports on Form 8-K, filed August 12, 1999,
     September 9, 1999, December 14, 1999 and January 14, 2000 pursuant to the
     Exchange Act; and

     (d) The description of the Common Stock under the caption "Description of
     Registrant's Securities to be Registered" incorporated by reference into
     the Company's Registration Statement on Form 8-A, filed on October 4, 1988
     pursuant to the Exchange Act and contained in the Company's Prospectus,
     filed on November 5, 1986 pursuant to the Securities Act as part of the
     Company's Registration Statement on Form S-18 (No. 2-99268-NY) under the
     caption "Description of Securities", as amended by the information under
     the caption "Description of Capital Stock" contained in the Company's
     Registration Statement on Form S-2, filed on October 16, 1992 pursuant to
     the Securities Act.

     In addition, all documents filed by the Company with the Commission
pursuant to Sections 13(a), 13(c), 14 and 15(d) of the Exchange Act subsequent
to the date of this Registration Statement and prior to the filing of a
post-effective amendment which indicates that all the securities offered hereby
have been sold or which deregisters all securities then remaining unsold shall
be deemed to be incorporated by reference in this Registration Statement and to
be a part hereof from the date of the filing of such documents with the
Commission. Any statement contained in a document incorporated by reference
herein shall be deemed to be modified or superseded for purposes hereof to the
extent that a statement contained herein (or in any other subsequently filed
document which also is



<PAGE>


incorporated by reference herein) modifies or supersedes such statement. Any
statement so modified or superseded shall not be deemed to constitute a part
hereof except as so modified or superseded.

Item 4. DESCRIPTION OF SECURITIES

     Inapplicable

Item 5. INTERESTS OF NAMED EXPERTS AND COUNSEL

     The validity of the shares of Common Stock offered hereby is being passed
upon for the Company by Willkie Farr & Gallagher. As of the date of this
Registration Statement, Harvey L. Sperry, a partner of Willkie Farr & Gallagher,
is a non-employee director of the Company and is the beneficial owner of
73,695 shares of Common Stock. Mr. Sperry may receive discretionary grants of
Common Stock in lieu of cash compensation under the Incentive Plan to the same
degree as other non-employee directors of the Company.

Item 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS

     Under Delaware law, corporations may limit the liability of directors,
except in connection with the following instances: (a) breaches of the
director's duty of loyalty to the corporation or its shareholders; (b) acts or
omissions not in good faith, or involving intentional misconduct or knowing
violation of law; (c) the payment of unlawful dividends or unlawful stock
repurchases or redemptions; or (d) transactions in which the director received
an improper personal benefit. Such limitation of liability provision does not
limit the liability of a director for violation of, or otherwise relieve the
Company or its directors from the necessity of complying with, federal or state
securities laws or affect the availability of non-monetary remedies such as
injunctive relief or rescission.

     The Company's Certificate of Incorporation eliminates the liability of
directors to the fullest extent permissible under Delaware law, as such law
currently exists or as it may be amended in the future. Furthermore, a provision
of Delaware law states that the indemnification provided by statute shall not be
deemed exclusive of any other rights under any bylaw, agreement, vote of
shareholders or disinterested directors or otherwise.

Item 7. EXEMPTION FROM REGISTRATION CLAIMED

Item 8. EXHIBITS

Exhibit No.    Description of Exhibits
-----------    -----------------------

    5          Opinion of Willkie Farr & Gallagher regarding the legality of the
               securities being registered.

  23.1         Consent of Arthur Andersen LLP.

  23.2         Consent of Willkie Farr & Gallagher (included in Exhibit 5).

  24           Power of Attorney (reference is made to the signature page).

Item 9. UNDERTAKINGS

     1. The undersigned registrant hereby undertakes:

     (a) To file, during any period in which offers or sales are being made, a
post-effective amendment to the Registration Statement:

          (i) to include any prospectus required by Section 10(a)(3) of the
          Securities Act;

          (ii) to reflect in the prospectus any facts or events arising after
          the effective date of the 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 the Registration Statement;

          (iii) to include any material information with respect to the plan of
          distribution not previously disclosed in the Registration Statement or
          any material change to such information in the Registration Statement;

provided, however, that paragraphs (a)(i) and (a)(ii) 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 Company pursuant to
Section 13 or Section 15(d) of the Exchange Act that are incorporated by
reference in the Registration Statement.

     (b) 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.



<PAGE>


     (c) 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.

     2. The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the Company's
annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act
that is incorporated by reference in the 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.

     3. Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
Company pursuant to the foregoing provisions, or otherwise, the Company 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 Company of expenses incurred or paid
by a director, officer or controlling person of the Company 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
Company 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.


                                   SIGNATURES

     Pursuant to the requirements of the Securities Act, the Company certifies
that it has reasonable grounds to believe that it meets all of 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 Boulder, State of Colorado, on this 18th day of April, 2000.

Item 3. INCORPORATION OF CERTAIN DOCUMENTS BY REFERENCE

     The following documents, filed with the Securities and Exchange Commission
(the "Commission") by Hauser, Inc., a Delaware corporation (the "Company"), are
incorporated by reference into the Registration Statement:

     (a) The Company's Annual Report on Form 10-K (File No. 0-17174) for the
     fiscal year ending April 30, 1999, as amended by the amendment on Form
     10-K/A, filed on October 27, 1999 pursuant to the Securities Exchange Act
     of 1934, as amended (the "Exchange Act");

     (b) The Company's Quarterly Reports on Form 10-Q for the quarters ended
     July 31, 1999, October 31, 1999 and January 31, 2000, filed pursuant to the
     Exchange Act;

     (c) The Company's Current Reports on Form 8-K, filed August 12, 1999,
     September 9, 1999, December 14, 1999 and January 14, 2000 pursuant to the
     Exchange Act; and

     (d) The description of the Common Stock under the caption "Description of
     Registrant's Securities to be Registered" incorporated by reference into
     the Company's Registration Statement on Form 8-A, filed on October 4, 1988
     pursuant to the Exchange Act and contained in the Company's Prospectus,
     filed on November 5, 1986 pursuant to the Securities Act as part of the
     Company's Registration Statement on Form S-18 (No. 2-99268-NY) under the
     caption "Description of Securities", as amended by the information under
     the caption "Description of Capital Stock" contained in the Company's
     Registration Statement on Form S-2, filed on October 16, 1992 pursuant to
     the Securities Act.

     In addition, all documents filed by the Company with the Commission
pursuant to Sections 13(a), 13(c), 14 and 15(d) of the Exchange Act subsequent
to the date of this Registration Statement and prior to the filing of a
post-effective amendment which indicates that all the securities offered hereby
have been sold or which deregisters all securities then remaining unsold shall
be deemed to be incorporated by reference in this Registration Statement and to
be a part hereof from the date of the filing of such documents with the
Commission. Any statement contained in a document incorporated by reference
herein shall be deemed to be modified or superseded for purposes hereof to the
extent that a statement contained herein (or in any other subsequently filed
document which also is
incorporated by reference herein) modifies or supersedes such statement. Any
statement so modified or superseded shall not be deemed to constitute a part
hereof except as so modified or superseded.

Item 4. DESCRIPTION OF SECURITIES

     Inapplicable

Item 5. INTERESTS OF NAMED EXPERTS AND COUNSEL

     The validity of the shares of Common Stock offered hereby is being passed
upon for the Company by Willkie Farr & Gallagher. As of the date of this
Registration Statement, Harvey L. Sperry, a partner of Willkie Farr & Gallagher,
is a non-employee director of the Company and is the beneficial owner of
73,695 shares of Common Stock. Mr. Sperry may receive discretionary grants of
Common Stock in lieu of cash compensation under the Incentive Plan to the same
degree as other non-employee directors of the Company.

Item 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS

     Under Delaware law, corporations may limit the liability of directors,
except in connection with the following instances: (a) breaches of the
director's duty of loyalty to the corporation or its shareholders; (b) acts or
omissions not in good faith, or involving intentional misconduct or knowing
violation of law; (c) the payment of unlawful dividends or unlawful stock
repurchases or redemptions; or (d) transactions in which the director received
an improper personal benefit. Such limitation of liability provision does not
limit the liability of a director for violation of, or otherwise relieve the
Company or its directors from the necessity of complying with, federal or state
securities laws or affect the availability of non-monetary remedies such as
injunctive relief or rescission.

     The Company's Certificate of Incorporation eliminates the liability of
directors to the fullest extent permissible under Delaware law, as such law
currently exists or as it may be amended in the future. Furthermore, a provision
of Delaware law states that the indemnification provided by statute shall not be
deemed exclusive of any other rights under any bylaw, agreement, vote of
shareholders or disinterested directors or otherwise.

Item 9. UNDERTAKINGS

     1. The undersigned registrant hereby undertakes:

     (a) To file, during any period in which offers or sales are being made, a
post-effective amendment to the Registration Statement:

          (i) to include any prospectus required by Section 10(a)(3) of the
          Securities Act;

          (ii) to reflect in the prospectus any facts or events arising after
          the effective date of the 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 the Registration Statement;

          (iii) to include any material information with respect to the plan of
          distribution not previously disclosed in the Registration Statement or
          any material change to such information in the Registration Statement;

provided, however, that paragraphs (a)(i) and (a)(ii) 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 Company pursuant to
Section 13 or Section 15(d) of the Exchange Act that are incorporated by
reference in the Registration Statement.

     (b) 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.
(c) 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.

     2. The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the Company's
annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act
that is incorporated by reference in the 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.

     3. Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
Company pursuant to the foregoing provisions, or otherwise, the Company 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 Company of expenses incurred or paid
by a director, officer or controlling person of the Company 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
Company 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.

                                   SIGNATURES

     Pursuant to the requirements of the Securities Act, the Company certifies
that it has reasonable grounds to believe that it meets all of 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 Boulder, State of Colorado, on this 18th day of April, 2000.
