Dear Hauser Shareholder:

   

         You are cordially invited to attend the Special Meeting of Shareholders
(the "SPECIAL MEETING") of Hauser, Inc. ("HAUSER") on __________________, 1999,
at 10:00 a.m. Mountain Time at __________________, Boulder, CO 80301.

    

         At this important meeting, you will be asked to approve (1) the 
Agreement and Plan of Merger, dated as of December 8, 1998 (the "MERGER 
AGREEMENT"), among Hauser, Zuellig Group N.A., Inc. ("ZGNA"), Zuellig 
Botanicals, Inc. ("ZBI"), a subsidiary of ZGNA, and certain other parties, 
and (2) the issuance to ZGNA and ZBI of shares of Common Stock of Hauser 
representing 49% of the issued and outstanding shares after giving effect to 
such issuance, subject to adjustment under certain circumstances. Pursuant to 
the terms of the Merger Agreement, three newly formed subsidiaries of Hauser 
will merge with and into three subsidiaries of ZGNA and, as a result, the 
three ZGNA subsidiaries will become wholly owned subsidiaries of Hauser (the 
"MERGER").

         The proposed Merger is described in the accompanying Proxy 
Statement, the beginning of which includes a summary of the terms of the 
Merger Agreement and certain other information relating to the proposed 
transaction.

         Adams Harkness & Hill ("AHH") was retained by Hauser to act as its 
independent financial advisor in connection with the Merger. As discussed in 
the accompanying Proxy Statement, AHH has delivered to the Hauser Board of 
Directors (the "BOARD") its written opinion that, as of December 8, 1998, and 
based upon and subject to certain matters stated in its written opinion, the 
terms of the Merger Agreement are fair, from a financial point of view, to 
Hauser and its shareholders.

   

         ON DECEMBER 8, 1998 THE BOARD UNANIMOUSLY APPROVED THE MERGER 
AGREEMENT AND THE PROPOSED STOCK ISSUANCE TO ZGNA AND ZBI. THE BOARD 
UNANIMOUSLY RECOMMENDS THAT SHAREHOLDERS VOTE FOR THE APPROVAL OF THE MERGER 
AGREEMENT.

    
   

         At the Special Meeting, you will also be asked to approve a 
resolution of the Board to effect a reverse stock split of the outstanding 
shares of Common Stock, with an exchange ratio of between two (2) and five 
(5) shares (the "REVERSE STOCK SPLIT"), and to consider and act upon the 
adoption of the Hauser 1999 Stock Incentive Plan (the "1999 STOCK INCENTIVE 
PLAN"). The resolution authorizing the Board to effect the Reverse Stock 
Split will be effective if (1) the Merger is approved and (2) the Reverse 
Stock Split is necessary to meet the NASDAQ minimum bid price on the Closing 
Date of the Merger. NASDAQ, where the Hauser Common Stock is traded, has 
advised Hauser that under NASDAQ National MarketPlace Rule 4330(f), the 
Merger constitutes a change in control. If Hauser Common Stock is to continue 
to be listed on the NASDAQ National Market, Hauser must satisfy the 
requirements for initial listing, including the minimum bid price of $5.00 
per share for trading. The Reverse Split is recommended to permit Hauser to 
comply with the NASDAQ National Market minimum bid price. After the Reverse 
Split is accomplished, management believes that Hauser will continue to be 
listed on the NASDAQ National Market. ZGNA and ZBI are not obligated to cause 
the Merger to occur if Hauser's Common Stock is not listed on the NASDAQ 
National Market or on another stock exchange.

    
   

         THE BOARD UNANIMOUSLY RECOMMENDS A VOTE FOR THE 1999 STOCK INCENTIVE 
PLAN AND THE REVERSE STOCK SPLIT CONTINGENT UPON THE APPROVAL

                                       i
<PAGE>

OF THE MERGER AGREEMENT. THE APPROVAL OF THE MERGER AGREEMENT IS NOT 
CONTINGENT UPON APPROVAL OF THE REVERSE STOCK SPLIT; HOWEVER, ZGNA AND ZBI 
ARE NOT OBLIGATED TO CAUSE THE MERGER TO OCCUR IF HAUSER'S COMMON STOCK IS 
NOT LISTED ON THE NASDAQ NATIONAL MARKET, OR ON SOME OTHER STOCK EXCHANGE. 
APPROVAL OF THE MERGER IS NOT CONTINGENT UPON APPROVAL OF THE 1999 STOCK 
INCENTIVE PLAN. ADOPTION OF BOTH THE 1999 STOCK INCENTIVE PLAN AND THE 
REVERSE STOCK SPLIT ARE CONTINGENT UPON APPROVAL OF THE MERGER AGREEMENT.

    

         Information concerning the matters to be considered and voted upon 
at the Special Meeting is set forth in the attached Notice of Special Meeting 
and Proxy Statement. All shareholders are cordially invited to attend the 
Special Meeting in person. Your participation at this meeting is very 
important, regardless of the number of shares you hold. Whether or not you 
plan to attend the Special Meeting, please complete, date, sign and return 
the accompanying proxy promptly in the enclosed envelope. If you attend the 
Special Meeting, you may revoke your proxy and vote your shares in person.

         Thank you for your prompt attention.

                                       Sincerely,

                                       HAUSER, INC.

                                 PROXY STATEMENT
                         SPECIAL MEETING OF SHAREHOLDERS
                         TO BE HELD ______________, 1999

   

         This Proxy Statement (the "PROXY STATEMENT") is being furnished to
holders of common stock, par value $.001 per share (the "COMMON STOCK"), of
Hauser, Inc., a Colorado corporation ("HAUSER"), in connection with the
solicitation of proxies by the Board of Directors of Hauser (the "BOARD") for
use at the Special Meeting of Shareholders of Hauser (the "SPECIAL MEETING") to
be held at 10:00 a.m. Mountain Time, on ____________________________, 1999 at
__________________, Boulder, Colorado, and at any and all adjournments of the
Special Meeting.

    
   

         This Proxy Statement relates to the proposed acquisition by Hauser 
of three subsidiaries of Zuellig Group, N.A., Inc., a Delaware corporation 
("ZGNA"), pursuant to the Agreement and Plan of Merger, dated as of December 
8, 1998, by and among Hauser, ZGNA, Zuellig Botanicals, Inc., a Delaware 
corporation and a subsidiary of ZGNA ("ZBI"), and certain other parties (the 
"MERGER AGREEMENT"). Pursuant to the Merger Agreement, ZGNA and ZBI will 
receive shares of Common Stock representing 49% of the issued and outstanding 
shares of Common Stock, after giving effect to such issuance, subject to 
adjustment as described herein. Pursuant to applicable rules of the NASDAQ 
National Market, the shareholders of Hauser are requested to consent to the 
issuance of shares of Common Stock contemplated by the Merger Agreement 
because the shares to be issued to ZGNA and ZBI exceed 20% of Hauser's 
outstanding shares of Common Stock and may be deemed to constitute a change 
in control. The NASDAQ National Market has advised Hauser that under NASDAQ 
National Market rules the Merger constitutes a change in control which will 
require Hauser to meet the requirements for an initial listing, including a 
minimum bid price of $5 per share, if Hauser Common Stock is to continue to 
be listed on the NASDAQ National Market. Consummation of the Merger Agreement 
is subject to various conditions, including the approval of the Hauser 
shareholders and the listing of the Common Stock on the NASDAQ National 
Market or on another stock exchange.

    
   

         At the Special Meeting, Hauser shareholders will also be asked to 
approve the resolution of the Board to effect a reverse stock split of the 
outstanding shares of Common Stock, with an exchange ratio of between two (2) 
and five (5) shares (the "REVERSE STOCK SPLIT"), and the Hauser, Inc. 1999 
Stock Incentive Plan (the "1999 STOCK INCENTIVE PLAN"). The resolution 
authorizing the Board to effect the Reverse Stock Split will be effective if 
(1) the Merger is approved and (2) the Reverse Stock Split is necessary to 
meet the NASDAQ minimum bid price on the Closing Date of the Merger. 

    
   

         THE BOARD HAS UNANIMOUSLY APPROVED THE MERGER AGREEMENT, THE 
ISSUANCE OF COMMON STOCK TO ZGNA AND ZBI, THE REVERSE STOCK SPLIT AND THE 
1999 STOCK INCENTIVE PLAN. THE BOARD UNANIMOUSLY RECOMMENDS THAT SHAREHOLDERS 
VOTE FOR THE APPROVAL OF THE MERGER AGREEMENT AND ISSUANCE OF COMMON STOCK TO 
ZGNA AND ZBI, THE REVERSE STOCK SPLIT AND THE 1999 STOCK INCENTIVE PLAN. THE 
APPROVAL OF THE MERGER AGREEMENT AND ISSUANCE OF SHARES OF COMMON STOCK TO 
ZGNA AND ZBI ARE NOT CONTINGENT ON ADOPTION OF THE 1999 STOCK INCENTIVE PLAN 
OR THE APPROVAL OF THE REVERSE STOCK SPLIT, BUT ADOPTION OF THE 1999 STOCK 
INCENTIVE PLAN AND THE REVERSE STOCK SPLIT ARE CONTINGENT UPON APPROVAL OF 
THE MERGER AGREEMENT AND THE ISSUANCE OF COMMON STOCK TO ZGNA AND ZBI.

    

         SHAREHOLDERS WHO EXECUTE PROXIES FOR THE SPECIAL MEETING MAY REVOKE 
THEIR PROXIES AT ANY TIME PRIOR TO THEIR EXERCISE BY DELIVERING WRITTEN 
NOTICE OF REVOCATION TO HAUSER, BY DELIVERING A DULY EXECUTED PROXY CARD 
BEARING A LATER DATE, OR BY ATTENDING THE SPECIAL MEETING AND VOTING IN 
PERSON.

PURPOSE OF THE SPECIAL MEETING

   

         At the Special Meeting, Hauser shareholders will consider and vote 
upon the Merger Agreement, the issuance by Hauser of shares of Common Stock 
to ZGNA and ZBI, the Reverse Stock Split and the 1999 Stock Incentive Plan. 
Hauser shareholders will also consider and vote upon any other matter that 
may properly come before the Special Meeting. Pursuant to applicable rules of 
the NASDAQ National Market System, the shareholders of Hauser are requested 
to consent to the issuance of Common Stock to ZGNA and ZBI pursuant to the 
Merger Agreement because the shares of Common Stock to be issued to ZGNA and 
ZBI exceed 20% of Hauser's outstanding shares of Common Stock and may be 
deemed to constitute a change in control. In addition, the purpose of the 
Reverse Stock Split is to maintain continued listing of Hauser's Common Stock 
on the NASDAQ National Market System. NASDAQ has advised Hauser that under 
NASDAQ National MarketPlace Rules, the Merger constitutes a change in 
control which will require Hauser to meet the requirements for initial 
listing, including a minimum bid price of $5 per share, if Hauser's Common 
Stock is to continue to be listed on the NASDAQ National Market. See 
"Approval of Reverse Stock Split."

    
REQUIRED VOTE; RECORD DATE
   

         The presence in person or by proxy of the holders of forty percent 
(40%) of the total issued and outstanding shares of Common Stock is necessary 
in order to constitute a quorum for the Special Meeting. Assuming a quorum is 
present in person or by proxy, each proposal will be approved if the votes 
cast in favor of adoption of the proposal exceed the votes cast against the 
proposal. Abstentions and broker non-votes, if any, will not be included in 
vote totals and, as such, will have no effect on the proposed vote on the 
Merger Agreement and stock issuance to ZGNA and ZBI, the Reverse Stock Split 
or the 1999 Stock Incentive Plan. Only holders of Common Stock on the close 
of business on the Record Date will be entitled to notice of and to vote at 
the Special Meeting.

    
THE MERGER AGREEMENT

GENERAL
   

         Pursuant to the Merger Agreement, at the Effective Time, a newly 
formed, wholly owned subsidiary of Hauser will merge into each of the 
Contributed Subsidiaries (the "MERGER"). As a result of the Merger, each of 
the Contributed Subsidiaries will become wholly owned subsidiaries of Hauser, 
and the former shareholders of the Contributed Subsidiaries, ZGNA and ZBI 
will receive shares of Common Stock aggregating 49% of the issued and 
outstanding shares of Common Stock after giving effect to such issuance. The 
number of shares to be issued to ZGNA and ZBI are subject to downward 
adjustment under certain circumstances. See "THE MERGER AGREEMENT- The Escrow 
Agreement". The Common Stock issued pursuant to the Merger Agreement will not 
be registered with the Securities and Exchange Commission and will be issued 
pursuant to an exemption from the registration requirements of the Securities 
Act of 1933, as amended. See "THE MERGER AGREEMENT -  General".

    
CONDITIONS
   

         Consummation of the Merger Agreement is subject to the satisfaction 
or waiver of conditions, including (i) obtaining requisite Hauser shareholder 
approval; (ii) the absence of any injunction or other similar order; (iii) 
the availability of certain financing arrangements; and (iv) the receipt of 
certain consents or approvals, including the listing of Hauser Common Stock 
on the NASDAQ National Market or on another stock exchange. See "THE MERGER 
AGREEMENT -Conditions of the Merger".

TERMINATION
   

         The Merger Agreement may be terminated at any time with the consent 
of the parties and under certain other circumstances at the election of 
either ZGNA or Hauser. If (1) Hauser shareholders do not approve the Merger 
Agreement, or (2) the Board withdraws, modifies or amends its recommendation 
that the Merger Agreement be approved by Hauser shareholders, Hauser will be 
obligated upon termination of the Merger Agreement to pay all of the 
reasonable out-of-pocket expenses ZGNA incurred in connection with the 
transaction, up to $500,000. In addition, if Hauser, within 12 months of a 
termination of the Merger Agreement under the circumstances described above, 
sells a number of shares of Common Stock equal to 49% or more of the issued 
and outstanding shares of Common Stock in a sale of securities, merger or 
reorganization, or sells all or substantially all of its assets, Hauser will 
be required to pay to ZGNA $1,500,000 as a termination fee. See "THE MERGER 
AGREEMENT- Break-Up Fee". In addition, Hauser has granted to ZGNA an option 
to acquire 2,000,000 shares of Common Stock at a price of $4.11 per share 
(the "OPTION"). The Option becomes exercisable if the Merger does not occur 
and Hauser, within nine months of the termination of the Merger Agreement, 
has had 20% or more of its stock acquired by, has merged with, or has sold 
all or substantially all its assets to a person or entity other than ZGNA or 
its affiliates. See "CERTAIN ANCILLARY AGREEMENTS - Agreement for Option to 
Acquire Common Stock of Hauser".

    
GOVERNANCE AND MANAGEMENT OF HAUSER AFTER THE MERGER

         Upon consummation of the Merger, the Board will consist of nine 
directors, three of whom will be appointed by the current Board (the 
"CONTINUING DIRECTORS"), three of whom will be appointed by ZGNA (the "ZGNA 
DIRECTORS"), and three of whom will be independent directors (the 
"INDEPENDENT DIRECTORS"). ZGNA and ZBI have agreed to vote the Common Stock 
owned by them for the persons designated as Independent Directors and 
Continuing Directors for five years, unless ZGNA owns less than 20% of the 
Common Stock. In addition, at the time of the Merger, Mr. Volker Wypyszyk, 
the Chief Executive Officer of ZGNA, will become the Co-Chief Executive 
Officer of Hauser with Dr. Dean Stull. See "MANAGEMENT AFTER THE MERGER".

RECOMMENDATION OF THE BOARD
   

         THE BOARD HAS UNANIMOUSLY APPROVED THE MERGER AGREEMENT AND THE 
ISSUANCE OF COMMON STOCK TO ZGNA AND ZBI AND RECOMMENDS THAT SHAREHOLDERS 
VOTE FOR THE MERGER AGREEMENT AND THE ISSUANCE OF COMMON STOCK TO ZGNA AND 
ZBI. SEE "THE SPECIAL MEETING - PURPOSE OF THE SPECIAL MEETING".

    
   

         THE BOARD HAS UNANIMOUSLY APPROVED THE REVERSE STOCK SPLIT AND THE 
1999 STOCK INCENTIVE PLAN AND RECOMMENDS THAT SHAREHOLDERS VOTE FOR THE 
REVERSE STOCK SPLIT AND FOR THE 1999 STOCK INCENTIVE PLAN.

    
OPINION OF FINANCIAL ADVISOR

         Adams, Harkness & Hill, Inc., the financial advisor to the Board 
("AHH"), delivered its written opinion to the Board to the effect that as of 
December 8, 1998, the consideration to be paid to ZGNA and ZBI pursuant to 
the Merger Agreement was fair to the Hauser shareholders, from a financial 
point of view. The full text of the written opinion of AHH, which sets forth 
the assumptions made, matters considered and limitations on the review 
undertaken in connection with the opinion, is attached hereto as Appendix A. 
HOLDERS OF COMMON STOCK ARE URGED TO READ SUCH OPINION IN ITS ENTIRETY. See 
"THE MERGER - Opinion of Hauser's Financial Advisors".

                                  RISK FACTORS

         Holders of Common Stock should consider carefully all of the 
information contained in this Proxy Statement, including the following risk 
factors:

   
INTEGRATION OF COMPANIES MAY NOT BE SUCCESSFUL
    

         Hauser entered into the Merger Agreement with the expectation that 
the Merger will result in certain benefits to Hauser's business operations 
and activities in the extract and nutraceutical markets. Achieving the 
benefits of the Merger will depend in part upon the integration of the 
businesses of Hauser and the Contributed Subsidiaries in an efficient manner, 
and there can be no assurance that this will occur. The transition to a 
combined company will require substantial attention from management. Hauser 
management does not have the experience in integrating diverse operations on 
the scale represented by the Merger. The diversion of management attention 
and any difficulties encountered in the transition process could have an 
adverse effect on the revenues and operating results of Hauser. In addition, 
the process of combining the two organizations could cause the interruption 
of, or a disruption in, the activities of the businesses of Hauser, which 
could have a material adverse effect on Hauser. There can be no assurance 
that Hauser will realize any of the anticipated benefits of the Merger.

   
DILUTION OF OWNERSHIP INTEREST
    

         Following the Merger, the current shareholders of Hauser will own 
approximately 51%, subject to adjustment under certain circumstances, (see 
"THE MERGER AGREEMENT - The Escrow Agreement") of the outstanding shares of 
Common Stock. This represents substantial dilution of the ownership interest 
in Hauser of the current Hauser shareholders.

   
THIRD PARTIES MAY BE LESS LIKELY TO ATTEMPT TO GAIN CONTROL OF HAUSER
    
   

         Following the Merger, ZGNA and ZBI will hold shares of Common Stock 
aggregating 49% of the issued and outstanding shares of Common Stock, subject 
to downward adjustment under certain circumstances. Members of Hauser's 
management will hold approximately 3% of the issued and outstanding shares of 
Common Stock. Therefore, the management and affiliates of Hauser will hold an 
aggregate of approximately 52% of the Common Stock, as compared to the 
approximately 8% currently owned by management. Thus, members of Hauser's 
management and its affiliates will be able to largely determine the outcome 
of corporate actions requiring shareholder approval and otherwise to control 
the business of Hauser. Such control could preclude any unsolicited 
acquisition of Hauser and consequently adversely affect the market price of 
the Common Stock or make it less likely that shareholders will be able to 
participate in a transaction in which they might be offered a premium over 
the market price for their shares.

    
   

         In addition, ZGNA and ZBI have agreed, for a period of 18 months 
from the Closing Date and with certain limited exceptions, not to sell or 
otherwise dispose of any shares of Common Stock without the prior written 
consent of the Board. See "THE MERGER AGREEMENT -- Certain Covenants and 
Agreements --Standstill Agreement." This may also make it less likely during 
such period that a third party would attempt to gain control of Hauser, and 
could have the results described above.

    

NUTRACEUTICAL EXTRACTS -- SUPPLIERS AND CUSTOMERS

   

         For the past eight years, ZBE has purchased approximately 80% of its 
annual requirements of nutraceutical extracts from two subsidiaries of Martin 
Bauer GmbH & Co., a German manufacturer ("MARTIN BAUER"). The purchases have 
been made pursuant to an agreement which designated ZBE as the exclusive 
distributor for such products in the United States and Canada. A notice of 
termination was given to ZBE by the suppliers in July 1998. Thus far, such 
termination has not had an impact on ZBE's results of operations, and Martin 
Bauer continues to sell nutraceutical extracts to ZBE. Hauser intends and 
believes that it has the capability to manufacture most of the extracts 
previously supplied to ZBE pursuant to the distribution agreement

                                        4
<PAGE>

or to acquire other products from third parties. However, Hauser will not be 
able to supply all of the nutraceutical extract requirements of ZBE at the 
time of the Merger. Hauser will need to expand its production staff, acquire 
and modify plant and equipment, and develop particular expertise to 
manufacture certain products. Customers of ZBE have generally indicated to 
ZBE that Hauser-manufactured nutraceutical extracts, meeting customer 
specifications, would be acceptable. Although Hauser believes that it has 
both the technical ability and manufacturing capacity to manufacture such 
extracts, there can be no assurance that Hauser will be able to produce all 
of such nutraceutical extracts required by ZBE or that all of the present ZBE 
customers will accept nutraceutical extracts produced by Hauser.

    

COMPETITION FOR CUSTOMERS AND RAW MATERIALS

         Nutraceutical extracts have historically been produced by relatively 
small companies. However, because the market for consumer products containing 
such extracts has grown at the rate of 15% or more in each of the past three 
years, larger companies, including pharmaceutical companies, are beginning to 
sell consumers products that contain nutraceutical extracts. Such companies 
have stronger financial, research, technical, manufacturing, marketing and 
sales capabilities than Hauser and, therefore, can become effective 
competitors of Hauser.

         Hauser expects that the subsidiaries of Martin Bauer will seek to 
compete with Hauser in the sale of nutraceutical extracts to those customers 
of ZBE which previously purchased products manufactured by such subsidiaries 
and to other potential customers.

   

         Since nutraceutical extracts are derived from botanical raw 
materials, a substantial portion of which are collected in the wild, the 
ability to locate such products and purchase them at competitive prices plays 
a significant, if not determinative, role in the capability of a manufacturer 
to produce nutraceutical extracts. The continued growth of the nutraceutical 
extract market will increase the competition for the purchase of botanical 
products and will likely increase the price of such products. Adverse growing 
conditions, loss of habitat, plant disease and international political 
conditions can also reduce the amount of botanical raw materials which are 
available to manufacturers of extracts.

    

BUSINESS CONCENTRATION

         Although the Merger will provide Hauser with a much broader product 
range and potential geographic scope of customers, Hauser will no longer be 
in the paclitaxel business and the herb, nutraceutical and extracts business 
will be a far higher percentage of total revenues relative to its Technical 
Services division. As such, Hauser will be more greatly affected by any 
adverse business conditions unique to the herb, nutraceutical or extracts 
business. Rapid growth in the herb and nutraceuticals industry in general has 
tended in the recent past to be significantly affected by "new" products 
gaining the attention of the consuming public. If new products do not become 
available or attract the attention of the consuming public, or if the 
consuming public in general becomes less interested in natural health 
products, the growth rate of consumer health products could decline or even 
reverse. See "Unaudited Pro Forma Financial Statements".

   
NASDAQ NATIONAL MARKET
    
   

         NASDAQ has advised Hauser that it must file an initial listing 
application to satisfy the qualitative and quantitative listing requirements 
for listing on the National Market, including the minimum bid price of $5.00 
per share, because under NASDAQ National MarketPlace Rules, the Merger 
constitutes a change in control. It is a condition of the Merger that 
Hauser's Common Stock be listed on the National Market or on another stock 
exchange. Hauser has filed an initial listing application for the Common 
Stock, including the shares to be issued in connection with the Merger. There 
can be no assurance, however, that Hauser will satisfy the initial listing 
requirements even if the Reverse Split is approved or that Hauser will 
continue to satisfy the NASDAQ National Market requirements in the future. If 
Hauser's application for listing is not approved, there can be no assurance 
that Hauser will meet the requirements for listing on any other established 
trading market, including AMEX or the NASDAQ Small Cap Market.

                               THE SPECIAL MEETING

PURPOSE OF THE SPECIAL MEETING

   

         At the Special Meeting, Hauser shareholders will consider and vote upon
the Merger Agreement, the issuance of Common Stock to ZGNA and ZBI, the Reverse
Stock Split and the 1999 Stock Incentive Plan. Hauser shareholders will also
consider and vote upon any other matter that may properly come before the
Special Meeting.

    
   

         Pursuant to applicable rules of the NASDAQ National Market, Hauser's 
shareholders are requested to approve the issuance of Common Stock to ZGNA 
and ZBI in accordance with the Merger Agreement because the Common Stock to 
be issued exceeds 20% of Hauser's outstanding shares of Common Stock and may 
be deemed to constitute a change in control. In addition, in order to remain 
listed on the NASDAQ National Market, Hauser's shareholders must approve the 
Reverse Stock Split if the Common Stock does not meet the minimum bid price 
on the Closing Date of the Merger. See "Approval of the Reverse Stock Split".

    
   

         The Board has unanimously approved the Merger Agreement and issuance of
Common Stock to ZGNA and ZBI, the Reverse Stock Split and the 1999 Stock
Incentive Plan. The Board unanimously recommends that shareholders vote FOR the
approval of the Merger Agreement, the issuance of Common Stock to ZGNA and ZBI,
the Reverse Stock Split and the 1999 Stock Incentive Plan. THE APPROVAL OF THE
MERGER AGREEMENT IS NOT CONTINGENT UPON APPROVAL OF THE REVERSE STOCK SPLIT;
HOWEVER, ZGNA AND ZBI ARE NOT OBLIGATED TO CAUSE THE MERGER TO OCCUR IF HAUSER
COMMON STOCK IS NOT LISTED ON THE NASDAQ NATIONAL MARKET, OR ON SOME OTHER STOCK
EXCHANGE. APPROVAL OF THE MERGER IS NOT CONTINGENT UPON APPROVAL OF THE 1999
STOCK INCENTIVE PLAN. ADOPTION OF BOTH THE 1999 STOCK INCENTIVE PLAN AND THE
REVERSE STOCK SPLIT ARE CONTINGENT UPON APPROVAL OF THE MERGER AGREEMENT.

    

REQUIRED VOTE; RECORD DATE

   

         The presence in person or by proxy of the holders of forty percent 
(40%) of the total issued and outstanding shares of Common Stock is necessary 
in order to constitute a quorum for the Special Meeting. Assuming a quorum is 
present in person or by proxy, each proposal will be approved if the votes 
cast in favor of adoption of the proposal exceed the votes cast against the 
proposal. Broker non- votes, if any, will not be included in vote totals and, 
as such, will have no effect on the proposals relating to the Merger 
Agreement, the Reverse Stock Split or the 1999 Stock Incentive Plan.

    

         The Board has fixed ______, 1999 as the Record Date for determining
holders entitled to notice of and to vote at the Special Meeting. As of the
Record Date, there were ___________ shares of Common Stock outstanding, each of
which entitles the holder thereof to one vote on each matter to come before the
Special Meeting. Hauser also has authorized 800,000 shares of preferred stock,
$1.00 par value, none of which were outstanding as of the Record Date.

   

         If the enclosed proxy card is properly executed and received by 
Hauser in time to be voted at the Special Meeting, the shares represented 
thereby will be voted in accordance with the instructions marked thereon. 
PROPERLY EXECUTED PROXIES WITH NO INSTRUCTIONS INDICATED THEREON BE VOTED FOR 
APPROVAL AND ADOPTION OF THE MERGER AGREEMENT AND THE ISSUANCE OF COMMON 
STOCK TO ZGNA AND ZBI AND FOR APPROVAL OF THE REVERSE STOCK SPLIT AND THE 
1999 STOCK INCENTIVE PLAN.

SOLICITATION OF PROXIES

         The costs of the Special Meeting, including the costs of preparing and
mailing the Proxy Statement, Notice and Proxy Card, will be borne by Hauser.
Hauser may, in addition, use the services of its directors, officers and
employees to solicit proxies, personally or by telephone, but at no additional
salary or compensation. Hauser will also request banks, brokers, and others who
hold shares of Common Stock in nominee names to distribute proxy solicitation
materials to beneficial owners, and will reimburse such banks and brokers for
reasonable out-of-pocket expenses which they may incur in so doing.

                                   THE MERGER

BACKGROUND OF THE MERGER

         Since fiscal year 1997, during strategic planning sessions, budgeting
meetings and meetings of the Board of Directors, Hauser's management and Board
have been discussing the need to expand Hauser's sales force in the
nutraceuticals market and to acquire a significant source of raw material
supply.

         In December 1997, ZGNA initiated discussions with Hauser regarding a
possible business combination. At that time, ZGNA was in discussions with Martin
Bauer regarding the purchase by Martin Bauer of equity from ZGNA. The Martin
Bauer discussions also contemplated the acquisition of a facility in the United
States by ZGNA for the manufacturing of nutraceutical extracts which had been
supplied to ZGNA by Martin Bauer from its facilities located in Germany. In the
Martin Bauer discussions, a business combination with Hauser was considered as
the preferred means of obtaining such a United States facility. ZGNA and Hauser
exchanged confidentiality agreements in January 1998, and Hauser was advised by
ZGNA of the discussions with Martin Bauer.

         In February 1998, the Board met with representatives of AHH, an
investment banking firm with experience in providing advice to participants in
the dietary supplement industry, and other investment banking firms, to discuss
possible engagement as its investment advisor in connection with potential
strategic business transactions.

         In May 1998, ZGNA and Martin Bauer met with Hauser in Boulder,
Colorado, to discuss a possible business combination and to tour the herbal
extract manufacturing facilities of Hauser.

         In June 1998, Hauser retained AHH to advise Hauser in the discussions
with ZGNA and Martin Bauer.

         In June 1998, Martin Bauer terminated discussions with ZGNA stating
that the business structure proposed by ZGNA for the combination with Hauser,
whereby the Contributed Subsidiaries would have merged with Hauser, was not
acceptable. Martin Bauer advised that it was not prepared to contribute what it
viewed as its United States sales of nutraceutical extracts to Hauser, a public
company, in which Martin Bauer would have only a minority interest through its
ownership of ZGNA equity. ZGNA notified Hauser that the discussions with Martin
Bauer had terminated.

         During the period from July 1998 through early December 1998, Hauser
and ZGNA continued to discuss a combination of Hauser and the Contributed
Subsidiaries and the terms upon which it could occur. During such period,
investment banking, accounting and legal representatives of Hauser and ZGNA
engaged in due diligence efforts on behalf of their respective clients.

   

         During August 1998, management of ZGNA and Hauser discussed a possible
business combination in general terms. Hauser's advisors and management
discussed with the Board the business, accounting and legal issues regarding a
proposed transaction.

    
   

         On September 11, 1998, ZGNA and Hauser met to discuss the capital needs
of Hauser and a transaction structure including a proposed combination of the
nutruceutical extract businesses of Hauser and ZGNA. At the

                                        7
<PAGE>

meeting, ZGNA and Hauser management also discussed (a) a potential purchase by
ZGNA of $3 to $5 million of Hauser's raw material inventory to provide
additional cash to Hauser and (b) the terms of a contemplated post-merger credit
facility for Hauser.

    
   

         On September 24, 1998, ZGNA made a proposal to Hauser's management that
included (a) a $6,000,000 investment by ZGNA in Hauser preferred stock
representing 19.9% of the issued and outstanding Common Stock on a pre-issuance
"as-converted" basis, (b) ZGNA's providing raw material sourcing to Hauser and
(c) ZGNA's becoming the exclusive distributor of Hauser's products.

    
   

         On October 2, 1998, management of ZGNA and Hauser and their respective
investment advisors met at the New York City offices of The Beacon Group Capital
Services, LLC, investment advisors to ZGNA, to discuss the proposed business
combination. The discussion resulted in a proposal that the Contributed
Subsidiaries be merged with Hauser subsidiaries and that Hauser Common Stock be
issued to ZGNA.

    
   

         On October 16, 1998, management, legal counsel and representatives of
AHH held a telephone conference call with ZGNA's management, legal counsel and
investment advisors, to discuss the valuation, legal issues, transaction terms,
status of due diligence and bank credit facility. Extensive discussions were
held on the possible purchase by ZGNA of $6,000,000 of Hauser preferred stock.

    
   

         On November 16, 1998, Hauser's management, legal counsel and investment
advisor and ZGNA's management, legal counsel and investment advisors, held a
conference call to resolve the valuation issues, inventory purchase, Option
Agreement terms, option to purchase the powders business of ZBI, limitations on
ZGNA reselling Hauser stock, break-up fees, and the adjustment which would occur
if Hauser was successful in selling the paclitaxel assets. Prior to that call,
Hauser presented ZGNA and its advisors with a written summary of its positions.

    
   

         During the Merger discussions with ZGNA, Hauser received inquiries,
from time to time, from other companies regarding possible business
combinations. Such inquiries were reviewed by AHH and discussions were entered
into with one company. No proposals were presented to Hauser after any such
inquiries from or discussions with, third parties.

    
   

         On December 8, 1998, Hauser, ZGNA and ZBI entered into the Merger 
Agreement with the approval of the Board following a meeting in which Hauser 
representatives described the final terms of the Merger Agreement and several 
other agreements (collectively, the "ANCILLARY AGREEMENTS"), including a 
Governance Agreement (the "GOVERNANCE AGREEMENT") which would establish both 
the membership of the Board after the Merger and the corporate governance 
obligations of ZGNA during the five-year period after the Merger. The final 
transaction terms approved at the December 8 Board meeting included merger of 
three newly formed subsidiaries of Hauser with and into the Contributed 
Subsidiaries, issuance to ZGNA and ZBI of shares of Common Stock of Hauser 
representing 49% of the issued and outstanding shares of Common Stock, 
subject to adjustment under certain circumstances, and agreements as to 
inventory purchase, registration rights, an option for Hauser to purchase the 
powders business of ZBI, an option for ZGNA to acquire Common Stock under 
certain circumstances if the Merger does not occur, and certain other 
matters. See "THE MERGER AGREEMENT", "CERTAIN ANCILLARY AGREEMENTS" and 
"MANAGEMENT AFTER THE MERGER" for a detailed description of the final 
transaction terms. At such meeting, AHH advised that the Merger was fair to 
the Hauser shareholders from a financial point of view. See "THE MERGER - 
Opinion of Hauser's Financial Advisors".

    
   

         In February 1999, the parties amended the Merger Agreement to (i)
change the required shareholder vote needed to approve the Merger from a
majority of all outstanding shares to a majority of the quorum present in person
or by proxy at the Special Meeting in order to conform to a lower quorum
requirement as permitted by Colorado law, (ii) provide for settlement of
disputes by arbitration, and (iii) make changes to the Escrow Agreement to (a)
clarify the definition of paclitaxel business, (b) clarify the procedures by
which shares held in escrow will be returned and (c) clarify the minimum number
of shares to which ZGNA and ZBI are entitled, (iv)

                                        8
<PAGE>

make changes to the Governance Agreement to clarify provisions relating to the
replacement of directors and quorums, (v) provide that ZBI license the trade
name "Zuellig Botanical Extracts" and mark "Botanicals International" to ZBE and
(vi) provide that the goodwill associated with the use of the licensed trade
name and licensed mark will not be considered an asset of, or increase the value
of, ZBI for purposes of determining purchase price under the Powders Option
Agreement (as hereinafter defined).

    

HAUSER'S REASONS FOR THE MERGER

         In reaching its determination to approve and recommend the Merger
Agreement and related documents, the Board consulted with Hauser's management
and its financial, accounting and legal advisors. After careful deliberation of
presentations by such advisors and other factors discussed below, the Board
determined that the Merger, including the terms of the Merger Agreement and
Ancillary Agreements, is in the best interests of Hauser and its shareholders.
The Board considered a number of factors, including the future prospects of
Hauser following the Merger, the businesses of Hauser and the Contributed
Subsidiaries and the fairness of the terms of the Merger Agreement and the
Ancillary Agreements from an economic and commercial standpoint.

         Specific factors that the Board considered included the following:

                 (1)   Hauser and the Contributed Subsidiaries bring unique and
                       complementary strengths in nutraceutical sourcing, sales,
                       manufacturing, and extract functions and markets to the
                       proposed combined business enterprise. Hauser has
                       developed expertise in proprietary extraction and
                       purification technologies which enable the production of
                       purified materials with a readily ascertainable
                       concentration of active ingredients. The strength of the
                       Contributed Subsidiaries include their superior raw
                       biomass material sourcing capabilities and an established
                       sales force in the nutrition supplements, fine chemicals,
                       generic pharmaceutical products and botanical raw
                       materials markets. The combination of Hauser's technical
                       and manufacturing expertise with the sourcing and sales
                       and marketing experience of the Contributed Subsidiaries
                       represents an opportunity for significant revenue and
                       profit enhancement for Hauser following the Merger. The
                       success of the combined business enterprise depends,
                       however, on the ability of Hauser to continue to employ
                       the sales force and distribution network of the
                       Contributed Subsidiaries and to successfully integrate
                       Hauser, the Contributed Subsidiaries and their employees
                       after the Merger.

                 (2)   Following the Merger, Hauser expects to increase its
                       market share to become a leading supplier of herbal
                       extracts, botanical raw materials, and related products
                       to the nutritional market in the United States. Hauser
                       believes it will be the only United States based company
                       with a fully vertically integrated operation able to
                       source, process, manufacture, and distribute
                       nutraceuticals to the wholesale market including branded
                       product sellers. In addition, Hauser's integrated
                       research and development capability and proprietary
                       extraction technology will uniquely allow it to work with
                       its customers to provide a full range of solutions to
                       their product needs.

                 (3)   Because of the reputation and experience of Wilcox as a
                       purchaser of botanical raw materials and as a cultivator
                       of botanicals, the Merger will provide additional
                       sources, worldwide, from which Hauser may obtain the
                       botanical raw materials required for the manufacturing of
                       nutraceutical extracts.

                 (4)   The Merger will permit Hauser to focus its manufacturing
                       facilities and capabilities in a market where Hauser has
                       demonstrated an ability to substantially increase its
                       revenues. Currently, Hauser's manufacturing plant is
                       operating at only approximately 35% to 40% of capacity,
                       excluding equipment which will be decommissioned or sold
                       as a result of terminating its involvement in the
                       production of paclitaxel. Most of that capacity is
                       available for production of products currently marketed
                       by the Contributed

                                        9
<PAGE>

                       Subsidiaries.
   
                 (5)   The Merger will provide financing to Hauser through the
                       credit agreement with Wells Fargo Bank, National
                       Association (the "Bank"). The credit agreement will
                       provide a $35.0 million line of credit and a $10.0
                       million fixed asset line in support of the merged
                       companies. As Hauser will also assume approximately $19.0
                       million of the Contributed Subsidiaries' bank debt,
                       Hauser may borrow up to $20.0 million from the Bank, and
                       expects to apply approximately $10.0 million to capital
                       expenditures and $10.0 million to working capital.
                       Additionally, Hauser will repay its $6.0 million
                       indebtedness to First National Bank of Boston.
    

         In reaching its conclusions that the Merger Agreement is in the best
interests of Hauser and its shareholders, the Board also considered, among other
things, the following factors: (1) its knowledge of the business, operations,
properties, assets, financial condition, operating results and prospects of
Hauser and the Contributed Subsidiaries; (2) current industry, economic and
market conditions; (3) presentations by Hauser's management with respect to the
transactions contemplated by the Merger Agreement; (4) the opinion of AHH as to
the fairness, from a financial point of view, of the terms of the Merger
Agreement to Hauser and its shareholders; (5) the terms of the Merger Agreement
(see "THE MERGER AGREEMENT"); and (6) the opportunity for Hauser shareholders to
participate in a larger, more diversified company.

   

         The Board also considered the risks in the transaction, including the
potential for downward pricing pressure on Hauser's products as larger companies
enter the nutraceuticals business, the inherent challenges of integrating two
separate organizations, the need to modify and expand both the work force and
production capability of Hauser to fulfill the need for products previously
supplied to the Contributed Subsidiaries by Martin Bauer, the need to acquire
from third parties some products previously supplied from other sources which
Hauser does not have the capacity to produce in the short term, the dilution of
ownership interest of current Hauser shareholders, that as a result of the
Merger Agreement, Hauser shareholders may be less likely to participate in a
transaction in which a third party would offer a premium over market price for
their shares, competition for customers and raw materials, and increased
business concentration of Hauser following the sale of its paclitaxel assets.

    
   

         The above discussion includes all material factors, including negative
factors, considered by the Board in approving the Merger Agreement.

    

         In view of the variety of factors considered in connection with its
evaluation of the Merger Agreement, the Board did not find it practicable to and
did not quantify or otherwise assign relative weights to the specific factors
considered in reaching its determination.

         ACCORDINGLY, THE BOARD HAS UNANIMOUSLY APPROVED THE MERGER AGREEMENT
AND ANCILLARY AGREEMENTS AND UNANIMOUSLY RECOMMENDS THAT THE SHAREHOLDERS VOTE
FOR APPROVAL AND ADOPTION OF THE MERGER AGREEMENT.

INTERESTS OF CERTAIN PERSONS IN THE MERGER

         In considering the recommendation of the Board to approve the Merger
Agreement, shareholders should be aware that certain members of Hauser's
management and the Board have interests in the transactions contemplated by the
Merger Agreement in addition to the interests in the Merger Agreement as
shareholders of Hauser generally.

                                       10

         OPTION PLANS

         Pursuant to Hauser's 1999 Incentive Bonus Plan (the " 1999 BONUS
PLAN"), 281,300 options granted under the 1999 Bonus Plan will become
immediately vested and exercisable upon a change of control of Hauser. Of this
amount, 219,552, or 78% of the options granted under the 1999 Bonus Plan are
held by executive officers of Hauser or its wholly owned subsidiary. The
proposed stock issuance to ZGNA and ZBI constitutes a change of control of
Hauser for the purpose of the 1999 Bonus Plan.

         Although no options will be granted pursuant to the proposed 1999 Stock
Incentive Plan prior to the Merger, the 1999 Stock Incentive Plan does include
provisions for accelerated vesting of options granted thereunder upon a change
in control of Hauser. See "APPROVAL OF THE 1999 STOCK INCENTIVE PLAN". A change
in control may or may not be more likely following the Merger. Although a
significant block of stock will be controlled by ZGNA and ZBI, thus perhaps
increasing the likelihood of a change in control event, it may also be less
likely that a third party would attempt to acquire the Company in the next five
years as ZGNA and ZBI, under the terms of the Merger Agreement, agree not to
participate in certain change in control events without the approval of the
Board.

         DIRECTORS AND OFFICERS

         Upon completion of the Merger, the Board will consist of nine
directors, three of whom will be directors currently serving on Hauser's Board,
namely, Dr. Stull, currently Chief Executive Officer and Chairman of the Board,
who will be Chairman of the Board and a Co-Chief Executive Officer of Hauser
following the Merger, William E. Coleman, an outside director, and Robert F.
Saydah, an outside director. The remaining current directors will resign from
the Board and no longer be directors of Hauser after the Merger.

         In addition, the Board and management of Hauser determined that since
the Contributed Subsidiaries have employment agreements with certain of their
executives which would continue with Hauser or its subsidiaries after the
Merger, it would be appropriate and in the best interests of Hauser and its
shareholders to have corresponding employment agreements with Dr. Stull, Martin
C. Wehr, currently Chief Operating Officer of Hauser, and David I. Rosenthal,
currently Chief Financial Officer of Hauser. See "MANAGEMENT AFTER THE MERGER".
It is unlikely such agreements will be entered into with Messrs. Stull, Wehr and
Rosenthal if the Merger does not close.

         On January 27, 1999, the Compensation Committee of the Board recognized
the long term board service of Drs. Cristol and Tolbert, founding directors of
Hauser, by extending the exercise period of a total of 16,700 non-statutory
stock options held by them contingent upon shareholder approval of the Merger.
The exercise period of the options that were extended all expired less than five
years from January 27, 1999. The expiration date on these options was extended
five years from their original expiration date.

         Other than as provided herein, no officer or director has any interest
in the Merger other than as a shareholder or any agreement or understanding with
Hauser which provides for any increased or accelerated benefit or payment upon
the Merger or a change in control of Hauser.

OPINION OF HAUSER'S FINANCIAL ADVISOR

         AHH was retained by Hauser in February 1998 and signed an exclusive
engagement agreement with Hauser on June 1, 1998, to participate in the
negotiation, review and analysis of the terms of any proposed strategic
transaction and related transactions and documentation and, at the request of
the Board, render a written opinion to the Board concerning the fairness from a
financial point of view, to Hauser and its shareholders, of the consideration
received by or paid by Hauser in the strategic transaction.

         AHH delivered to the Board on December 1, 1998, its oral opinion,
subsequently confirmed in writing as of December 8, 1998, to the effect that, as
of the date of the written opinion, based on and subject to the assumptions,
factors and limitations set forth in the opinion and as described below, the
consideration proposed

                                       11
<PAGE>

to be received by ZGNA and ZBI in the Merger was fair, from a financial point of
view, to Hauser and its shareholders. THE FULL TEXT OF THE OPINION LETTER DATED
DECEMBER 8, 1998, FROM AHH (THE "AHH OPINION"), WHICH SETS FORTH THE PROCEDURES
FOLLOWED, THE ASSUMPTIONS MADE, MATTERS CONSIDERED AND LIMITATIONS ON THE REVIEW
UNDERTAKEN BY AHH, IS ATTACHED AS APPENDIX A TO THIS PROXY STATEMENT AND IS
INCORPORATED HEREIN BY REFERENCE. ALL SHAREHOLDERS ARE URGED TO READ THE AHH
OPINION IN ITS ENTIRETY.

         NOTE THAT CAPITALIZED TERMS USED IN THIS DESCRIPTION OF THE OPINION 
HAVE THE MEANING ASCRIBED TO THEM IN THE AHH OPINION AND NOT IN THIS PROXY 
STATEMENT, EXCEPT WHERE OTHERWISE INDICATED.

         The AHH Opinion was rendered to the Board and does not constitute a
recommendation to any shareholder of the Company as to how such shareholder
should vote at the Special Meeting. The AHH Opinion does not address the
Company's underlying business decision to proceed with or effect the Merger.

         In arriving at the AHH Opinion, AHH (1) reviewed Hauser's Annual
Reports, Forms 10-K and related financial information for the three fiscal years
ended April 30, 1998, and Hauser's Form 10-Q and the related unaudited financial
information for the six month period ended October 31, 1998; (2) reviewed the
audited financial statements of ZGNA, Wilcox and ZetaPharm for the three fiscal
years ended March 31, 1998, and the audited financial statements of ZBI for the
two fiscal years ended March 31, 1997; (3) analyzed certain internal financial
statements and other financial and operating data concerning Hauser prepared by
the management of Hauser; (4) analyzed certain internal financial statements and
other financial and operating data concerning the Contributed Subsidiaries
prepared by the management of ZGNA; (5) analyzed the potential pro forma
financial effects of the Merger on Hauser and the Contributed Subsidiaries; (6)
conducted due diligence discussions with members of senior management of Hauser
and ZGNA and discussed with members of senior management of Hauser and ZGNA
their views regarding future business, financial and operating benefits arising
from the Merger; (7) reviewed the historical market prices and trading activity
for the Common Stock and compared them with those of certain publicly traded
companies (collectively, the "PEER GROUPS") it deemed to be relevant and
comparable to Hauser and the Contributed Subsidiaries, respectively; (8)
compared the results of operations of Hauser and the Contributed Subsidiaries
with that of companies making up the Peer Groups; (9) compared the financial
terms of the Merger with the financial terms of certain other mergers and
acquisitions it deemed to be relevant and comparable to the Merger; (10)
participated in certain discussions among representatives of Hauser and ZGNA and
their financial and legal advisors; (11) reviewed the Merger Agreement and
agreements which are Exhibits thereto; and (12) reviewed such other financial
studies and analyses and performed such other investigations and took into
account such other matters as it deemed necessary, including its assessment of
general economic, market and monetary conditions.

         In delivering the AHH Opinion to the Board, AHH prepared and delivered
to the Board certain written materials containing various analyses and other
information material to the AHH Opinion. The following is a summary of these
materials.

         MARKET ANALYSIS. AHH reviewed general background information and
selected market trading data for Hauser relative to three Peer Groups consisting
of publicly traded companies: (1) seven branded nutritional supplement
manufacturers; (2) six private label nutritional supplement manufacturers; and
(3) seven value added distributors of specialty raw materials.

         IMPLIED TRANSACTION ECONOMICS. Based on the 20 day trading average of
the Common Stock as of November 25, 1998, of $3.594 and the proposed amount of
Common Stock to be issued by Hauser, AHH calculated an implied Market Value
(i.e., the product of the 20 day trading average and the proposed number of
shares of Common Stock) as of that date of the Contributed Subsidiaries of
$36,137,000 and, including long term debt of $6,000,000, an implied Enterprise
Value (i.e., Market Value plus long term debt assumed) of $42,137,000 for the
Contributed Subsidiaries. These implied values served as the numerator for
various ratios, being: (1) Enterprise Value divided by last twelve months
("LTM") revenue; (2) Enterprise Value divided by LTM earnings before interest
and taxes; (3) Market Value divided by LTM net profit after taxes; and (4)
Market Value divided by book value. Because of the diverse nature of the
combined companies, the ratios were then

                                       12
<PAGE>

compared to ratios derived from the three Peer Groups and 22 merger or 
acquisition transactions (the "PRECEDENT TRANSACTIONS") announced since May 
1996. (Of the 22 announced transactions, 21 were completed and one was 
terminated prior to completion). The Precedent Transactions were considered 
representative of recent transactions in the natural products industry and 
believed to possess characteristics similar to the Merger. In each case the 
value range and a mean excluding maximum and minimum values ("adjusted mean") 
were calculated and compared to the Merger.

         For the Merger, the ratio of Enterprise Value to LTM revenue (i.e., the
consideration paid by Hauser relative to the Contributed Subsidiaries) was 2.1x,
while the adjusted means from the Peer Groups and the Precedent Transactions
ranged between 1.0x and 2.3x, representing a range of $87.6 million to $201.5
million. For the Merger, the ratio of Enterprise Value to LTM earnings before
interest and taxes was 10.2x, while the adjusted means from the Peer Groups and
the Precedent Transactions ranged between 8.8x and 18.4x, representing a range
of $36.4 million to $76.1 million. For the Merger, the ratio of Market Value to
LTM to net profit after taxes was 27.5x, while the adjusted means from the Peer
Groups and the Precedent Transactions ranged between 12.8x and 31.6x,
representing a range of $16.8 million to $41.5 million. For the Merger, the
ratio of Market Value to book value was 3.5x, while the adjusted means from the
Peer Groups and the Precedent Transactions ranged between 2.2x and 10.9x,
representing a range of $23.0 million to $114.2 million. No one ratio was
determinative and each was considered in the analysis. Because of the nature and
timing of available data for the Contributed Subsidiaries, forecast data for the
Contributed Subsidiaries' fiscal year ending March 1999 was used in lieu of LTM
data in the calculation of the ratios.

         DILUTION/ACCRETION ANALYSIS. AHH examined the hypothetical pro forma
effect of the Merger on Hauser's forecasted earnings per share for the fiscal
years 1999 and 2000, without synergies or efficiencies anticipated by Hauser or
ZGNA management. This analysis indicated that the transaction would be accretive
to per share earnings in fiscal 2000. Estimated earnings for Hauser were based
on internal financial planning data furnished to AHH by management of Hauser.
Estimated earnings for the Contributed Subsidiaries were based on internal
financial planning data furnished to AHH by management of ZGNA and reviewed by
management of Hauser.

         CONTRIBUTION ANALYSIS. AHH also analyzed the expected relative
contributions of the Contributed Subsidiaries and Hauser to revenue, gross
profit and operating profit for fiscal year 1999 and fiscal year 2000, based
upon the above described forecasts of the Contributed Subsidiaries and Hauser.
The analysis was done without consideration of expected synergies or
efficiencies or the one month difference in the fiscal year ends of the
Contributed Subsidiaries relative to Hauser. The analysis indicated that during
these periods Hauser's contribution to combined revenues would range from 29.1%
and 31.9%, Hauser's contribution to gross profit would range from 47.5% to 50.4%
and Hauser's contribution to operating profit for FY 2000 would represent 66.3%
of the total figure. Based upon these figures, the Contributed Subsidiaries'
implied valuation would range from minimal to $91 million, with an average of
$54 million.

         In reaching its conclusion as to the fairness of the consideration to
be received in the Merger and in its presentation to the Board, AHH did not rely
on any single analysis or factor described above, assign relative weights to the
analyses or factors considered by it, or make any conclusions as to how the
results of any given analysis, taken alone, supported the AHH Opinion. The
preparation of a fairness opinion is a complete process and not necessarily
susceptible to partial analyses or summary description. AHH believes that its
analyses must be considered as a whole and that selecting portions of its
analyses and of the factors considered by it, without considering all factors
and analyses, would create a misleading view of the processes underlying the AHH
Opinion. The analyses of AHH are not necessarily indicative of actual values or
future results, which may be significantly more or less favorable than suggested
by such analyses. Analyses relating to the value of companies do not purport to
be appraisals or valuations or necessarily reflect the price at which companies
may actually be sold. No company or transaction used in any comparable analysis
as a comparison is identical to the Contributed Subsidiaries or Hauser, or the
Merger. Accordingly, an analysis of the results is not mathematical; rather, it
involves complex considerations and judgments concerning differences in the
various characteristics of the comparable companies and other factors that could
affect the public trading value of the comparable companies to which the
Contributed Subsidiaries and Hauser were compared.

                                       13
<PAGE>

         In connection with its review and arriving at it's fairness opinion,
AHH did not independently verify any information received from Hauser, ZGNA or
Contributed Subsidiaries, relied on such information, and assumed that all such
information was complete and accurate in all material respects. With respect to
any internal forecasts reviewed relating to the prospects of Hauser and the
Contributed Subsidiaries, it has assumed that they had been reasonably prepared
on bases reflecting the best currently available estimates and judgments of
Hauser's and ZGNA's management as to the future financial performance of Hauser
and the Contributed Subsidiaries. The fairness opinion was rendered on the basis
of securities market conditions prevailing as of the date of the opinion and on
the conditions and prospects, financial and otherwise, of Hauser and the
Contributed Subsidiaries as known to it on the date thereof. AHH did not
conduct, nor did it receive copies of, any independent valuation or appraisal of
any of the assets of Hauser and the Contributed Subsidiaries. In addition, it
assumed, with the consent of Hauser, that: (1) the Merger will be accounted for
under the purchase method in accordance with generally accepted accounting
principles as described in Accounting Principles Board Opinion Number 16; (2)
the Merger will constitute a tax-free reorganization under Section 368 of the
Internal Revenue Code of 1986, as amended; and (3) any material liabilities
(contingent or otherwise, known or unknown) of Hauser and the Contributed
Subsidiaries are as set forth in the financial statements of Hauser and the
Contributed Subsidiaries, respectively. Hauser did not set limitations on the
scope of AHH's investigation or the procedures to be followed in rendering its
opinion.

         Financial planning data and forecasts of Hauser and the Contributed
Subsidiaries was prepared based on numerous variables and assumptions that are
inherently uncertain, including, without limitation, factors related to general
economic and competitive conditions, and actual results could vary significantly
from those set forth in such financial planning data. AHH has assumed no
liability for such financial planning data and forecasts.

         AHH, as a customary part of its investment banking business, is engaged
in the evaluation of businesses and their securities in connection with mergers
and acquisitions, underwritings and other distributions of securities, private
placements and evaluations for estate, corporate and other purposes. The Board
selected AHH because of its expertise, reputation and familiarity with the
nutraceuticals and nutritional supplement industry in general. AHH does not make
a market in the Common Stock nor currently provide analyst coverage of Hauser.
In the ordinary course of its business, AHH and its affiliates may actively
trade securities of Hauser for its own account or the accounts of its customers
and, accordingly, may at any time hold a long or short position in the
securities.

   

         For rendering its services to Hauser's Board in connection with the 
Merger, Hauser paid AHH a $50,000 non-refundable cash retainer and $150,000 
for rendering the AHH Opinion upon rendering the AHH Opinion. Hauser will pay 
1.5% of the total consideration paid in the transaction upon consummation of 
the Merger. Hauser estimates that the total fee payable to AHH at Closing 
will be approximately $750,000, based upon the fair market value of Hauser's 
Common Stock as of March 31, 1999. The contingent nature of a portion of 
these fees may have created a potential conflict of interest in that Hauser 
would be unlikely to consummate the Merger unless it had received the AHH 
Opinion. Whether or not the Merger is consummated, Hauser has agreed to pay 
the reasonable out-of-pocket expenses of AHH and to indemnify AHH against 
certain liabilities incurred (including liabilities under the federal 
securities laws) in connection with the engagement of AHH by Hauser or the 
Merger. AHH had not otherwise been previously engaged by, or provided 
services to, Hauser in the preceding two years.

    

DISSENTERS' RIGHTS

         If the Merger Agreement and issuance of Common Stock to ZGNA and ZBI
are approved and the Merger is consummated, Hauser shareholders who oppose the
proposal will not have dissenters' rights to receive cash payment for the fair
market value of their shares under the Colorado Business Corporation Act or
otherwise.

NASDAQ LISTING

   

         NASDAQ has advised Hauser that the continued listing of Hauser's 
Common Stock on the NASDAQ National Market requires Hauser to file an initial 
listing application and to satisfy the requirements of such listing, 
including the minimum bid of $5.00 per share, because, under NASDAQ National 
MarketPlace Rules, the Merger constitutes a change in control. Hauser has 
filed the initial listing application which includes the

                                       14
<PAGE>

Common Stock to be issued in the Merger, and believes, upon completion of the
Reverse Split, that the Hauser Common Stock will continue to be listed on the
NASDAQ National Market. It is a condition of the obligation of ZGNA and ZBI to
consummate the Merger that Hauser's Common Stock be listed on the NASDAQ
National Market or on another stock exchange. Hauser believes that it will be
able to fulfill such condition if the Reverse Split is approved.

    

EXPECTED ACCOUNTING TREATMENT

   

         It is expected that the Merger will be accounted for under the purchase
method of accounting for financial reporting purposes, with Hauser as the
acquiror. Under the purchase method, assets acquired and liabilities assumed are
adjusted based upon estimates of fair market value as of the date of the closing
of the Merger ("CLOSING DATE"). Goodwill of approximately $33,470,000 will be
recorded as part of the Merger which will be amortized over twenty years.
However, the amount assigned to goodwill could decrease significantly if Hauser
is successful in generating net proceeds in excess of $3,000,000 from the sale
of its paclitaxel business. See "THE MERGER AGREEMENT - The Escrow Agreement".

    

FEDERAL INCOME TAX CONSEQUENCES

         Hauser and ZGNA expect that the Merger will constitute a tax-free
reorganization within the meaning of Section 368(a) of the Internal Revenue Code
of 1986 (the " CODE"), as amended, and that for federal income tax purposes, no
gain or loss will be recognized by Hauser upon receipt of the shares of the
Surviving Corporations or by ZGNA upon receipt of the Common Stock.

         Section 382 of the Code provides that if shareholders of a corporation
owning individually more than 5% of the stock of a corporation increase their
collective ownership by 50% or more percentage points within a three year
period, the result will be an "ownership change". As a result of the Merger,
ZGNA will increase its ownership of Hauser by as much as 49 percentage points.

         Based upon information required to be provided to Hauser pursuant to
the rules and regulations of the Securities and Exchange Commission, to the best
of Hauser's knowledge and belief no shareholder of Hauser either owned more than
5% of the Common Stock or increased ownership to the 5% level within the 3 year
period prior to the Merger. Accordingly, Hauser believes that the Merger will
not trigger an ownership change. However, it is very possible that the 50
percentage points threshold could be reached within three years of the Merger,
resulting in an ownership change at that time.

         The consequences of the ownership change would be that the utilization
of Hauser's net operating losses and credit carryovers available at that date
would be limited, on an annual basis, to an amount equal to the value of Hauser
immediately prior to the ownership change (reduced by the value of the
Contributed Subsidiaries at the Closing Date if the ownership change were to
occur within two years of the Merger), multiplied by the long term tax-exempt
rate (as defined in the Code). In addition, if Hauser should have a "net
unrealized built-in loss" (as defined in Section 382 of the Code) at the date of
the ownership change, the utilization of such losses when recognized would be
included with the carryovers subject to the limitation.

         The amount of net operating losses, credit carryforwards and net
unrealized built-in losses subject to the limitation, as well as the amount of
the limitation, would be determined at the time of any ownership change. As of
April 30, 1998, Hauser had net operating loss carryforward of approximately
$4,300,000. In addition, Hauser expects to incur an additional loss prior to the
Closing Date.

         NEITHER HAUSER NOR ZGNA HAS REQUESTED, NOR WILL THEY RECEIVE, AN
ADVANCE RULING FROM THE INTERNAL REVENUE SERVICE AS TO THE TAX
CONSEQUENCES OF THE MERGER.

                              THE MERGER AGREEMENT

         The following summary of the material features of the Merger Agreement
and related agreements is qualified in its entirety by reference to the full
text of the Merger Agreement, a copy of which is attached to this Proxy
Statement as Appendix B.

GENERAL

         Subject to the terms and conditions of the Merger Agreement, on the
effective date of the Merger (the "EFFECTIVE TIME"), three newly formed, wholly
owned subsidiaries of Hauser will merge with and into each of the Contributed
Subsidiaries, with the Contributed Subsidiaries continuing as the surviving
corporations. As a result of the Merger, each of the Contributed Subsidiaries
will become a wholly owned subsidiary of Hauser. The corporate existence and
identity of Hauser will continue unaffected by the Merger.

   

         As a result of the Merger, ZGNA and ZBI will become entitled to receive
shares of Common Stock representing an aggregate of 49% of the issued and
outstanding shares at the Effective Time, after giving effect to such issuance.
Based on the _______________ shares of Common Stock outstanding on the Record
Date, ZGNA and ZBI would receive __________ shares of Common Stock. If the
Reverse Split occurs, the number of such shares will be reduced on a pro rata
basis.

    

         The Common Stock issued as consideration for the Merger pursuant to 
the Merger Agreement (the "SHARES") will not be registered with the 
Securities and Exchange Commission ("SEC") and will be issued pursuant to an 
exemption from the registration requirements of the Securities Act of 1933, 
as amended (the "SECURITIES ACT"). As a result, the Shares will be subject to 
certain restrictions on transfer, except transfers in connection with an 
effective registration statement under the Securities Act and any applicable 
state securities laws, or an exempt transaction under such laws. ZGNA and ZBI 
have been granted certain rights to have the Shares registered for resale. 
See "CERTAIN ANCILLARY AGREEMENTS - Registration Rights Agreement".

THE ESCROW AGREEMENT

   

         Upon consummation of the Merger, certain shares of Common Stock 
otherwise issuable to ZGNA and ZBI will be placed in escrow pursuant to an 
escrow agreement to be entered into on the Closing Date between Hauser, ZGNA, 
ZBI and American Securities Transfer & Trust, Inc., as escrow agent (the 
"ESCROW AGREEMENT"). The number of shares to be placed in escrow (the "ESCROW 
SHARES") will be equal to the lesser of such number of shares of Common Stock 
as will result in ZGNA and ZBI owning 42% of the shares of Common Stock 
outstanding and such number of shares as will result in ZGNA and ZBI holding 
40% of the shares of Common Stock outstanding on a fully diluted basis (each 
after giving effect to the proposed issuance of Common Stock to ZGNA and ZBI 
and excluding the shares in escrow). If Hauser sells all or substantially all 
of its paclitaxel business for an amount in excess of $3,000,000 by October 
31, 1999, certain of the Escrow Shares will be returned to Hauser to be 
canceled. The exact number of Escrow Shares to be returned will equal the net 
proceeds received by Hauser in excess of $3,000,000 divided by $3.50. Net 
proceeds means the cash proceeds received from the sale of the paclitaxel 
assets realized by October 31, 1999 less (1) all cash costs incurred to 
complete production of the inventory into finished goods; (2) estimated costs 
to terminate cultivar contracts and (3) other cash costs incurred to exit the 
paclitaxel business. If all of the Escrow Shares are returned to Hauser, 
Hauser shareholders may hold up to 58% of the outstanding Common Stock and 
ZGNA and ZBI may hold 42% of the outstanding Common Stock following the 
Merger.

    

REPRESENTATIONS AND WARRANTIES

         The Merger Agreement contains various representations and warranties of
Hauser and its subsidiaries, ZGNA, ZBI, and the Contributed Subsidiaries

limitation representations and warranties as to: (1) corporate organization,
existence and good standing; (2) corporate power and authority to consummate the

CERTAIN COVENANTS AND AGREEMENTS

         Hauser and ZGNA have agreed (subject to an exception for Hauser's sale
of its paclitaxel business) that prior to the Closing Date, they will, and will
cause their subsidiaries to, among other things, conduct their respective
businesses in the ordinary course consistent with past practice and use
reasonable efforts to preserve intact their business organizations and
relationships with third parties.

   

         With certain limited exceptions, from the date of the Merger Agreement
to the Closing Date, neither Hauser and its subsidiaries nor the Contributed
Subsidiaries may, without the consent of the other party: (1) amend or propose
to amend its organizational documents in any material respect; (2) issue, grant,
sell, pledge, dispose, or propose to do the same, any shares of, or rights of
any kind to acquire or sell any shares of, its capital stock, except for (a) the

of Hauser and (b) options granted pursuant to the Incentive Plan or stock option
plan for directors in effect as of the signing date of the Merger Agreement for

incur any new indebtedness or make, assume, guarantee or otherwise become liable
for any new loans, advances, capital contributions or investments to any other
person outside the ordinary course of business; (5) acquire the stock or assets
of, or merge or consolidate with, any other person outside the ordinary course
of business; (6) sell, transfer, mortgage, pledge or otherwise dispose of or
encumber any material assets or property outside of the ordinary course of
business; or (7) fail to maintain insurance policies required by the Merger
Agreement.

    

         Prior to the Closing, and for three months thereafter, the timing and
content of all public announcements relating to the Merger and the transactions
contemplated thereby will be determined by mutual agreement of Hauser and ZGNA,
with the exception of disclosures that legal counsel advises are required by
applicable laws or rules of the National Association of Securities Dealers, Inc.

         For two years after the Closing Date, Hauser has agreed not to
liquidate or transfer outside the ordinary course of business more than an
insubstantial amount of the assets of ZBE to Hauser or one of its affiliates or
take any action that would jeopardize the characterization of the Merger as a
reorganization within the meaning of Section 368(a) of the Code.

         STANDSTILL AGREEMENT. ZGNA and ZBI have agreed, from the date of the
Merger Agreement to the Closing Date (or, if the Merger Agreement is terminated,
in accordance with its terms, for a period of 18 months from the date of the
Merger Agreement, if any), that they will not without the prior written consent
of the Board (1) acquire any voting stock or right to acquire voting stock,
other than upon exercise of the Option; (2) directly or indirectly make or
participate in any solicitation of proxies to vote or any agreement to vote, or
attempt to advise or influence any voting of Common Stock (except to the extent
necessary for ZGNA to have its three representatives on the Board); (3) make any
public announcement relating to any transaction or proposed transaction between
Hauser and any of its shareholders and ZGNA or any of its affiliates; (4)
disclose any intention or plan relating to any of the above; or (5) sell or
otherwise transfer any shares of Common Stock except in a transaction approved
by the Board.

                                       17
<PAGE>

         For a period of five years from the Closing Date, ZGNA and ZBI have
agreed that they will not without the prior written consent of the Board (1)
acquire more than 49% of Hauser's voting stock, or the right to acquire more
than 49% of Hauser's voting stock; (2) directly or indirectly make or
participate in any solicitation of proxies to vote or any agreement to vote, or
attempt to advise or influence any voting of Common Stock (except to the extent
necessary for ZGNA to have its three representatives on the Board); (3) make any
public announcement relating to any transaction or proposed transaction between
Hauser and any of its shareholders and ZGNA or any of its affiliates; (4)
disclose any intention or plan relating to any of the above; or (5) except in an
underwritten transaction, sell or otherwise transfer to the public more than the
greater of 1% of the outstanding shares of Common Stock in any two-week period
or 20% of the weekly trading volume of the Common Stock. In addition, for a
period of 18 months after the Closing Date and with certain limited exceptions,
ZGNA and ZBI will not sell or otherwise dispose of any of its shares of Common
Stock without the prior written consent of the Board.

         CONTINUED OWNERSHIP OF THE SHARES. In order to insure that ZGNA will
meet certain indemnification obligations under the Merger Agreement, ZGNA and
ZBI have agreed to own the shares of Common Stock, or other liquid assets of
approximately equivalent value to such shares, until the later of (1) the second
anniversary of the Closing; or (2) until final resolution of any claims for
indemnification asserted by Hauser under the Merger Agreement. However, after
the first anniversary of the Closing, ZGNA and ZBI are only required to hold
Shares or other liquid assets having a value of 60% of the initial value of the
Shares plus an amount equal to the value of any asserted or pending claims made
for indemnification under the Merger Agreement.

         NON-COMPETE. For a period of five years after the Closing Date, ZGNA,
and its parent corporation and affiliates have agreed to not directly or
indirectly engage in any businesses selling products or services in direct
competition with Hauser or its subsidiaries in North America as conducted on the
Closing Date or to acquire botanical raw materials used by Hauser for the
purpose of retail or wholesale sales in North America for use as a consumed
nutraceutical, or solicit any managerial, sales or purchasing employees with the
intent of enticing such employees away from their employment with Hauser or its
subsidiaries.

         CONTINUED EMPLOYMENT. ZGNA and its affiliates agree to use their
reasonable best efforts to cause Mr. Wypyszyk, for the first 12 months after the
Closing Date, to devote a significant amount of his time to the business of
Hauser, and after 12 months, to devote substantially all of his time to the
business of Hauser, and to not require Mr. Wypyszyk to devote time to the
business of ZGNA or its affiliates that would be inconsistent with this
obligation.

         SUBSCRIPTION RIGHT. If Hauser issues equity securities of any kind
after the date of the Merger Agreement, ZGNA has the right to purchase a portion
of the offered securities equal to the percentage of shares of Common Stock
beneficially owned by ZGNA prior to the proposed issuance. The subscription
right does not apply to a registered offering to the public in a firm commitment
underwriting or an acquisition of another entity by merger, purchase of
substantially all of the assets or stock or other form of acquisition or to
other customer exceptions.

         RECOMMENDATION. Hauser's Board will recommend to Hauser shareholders
that they approve the proposed Merger Agreement and issuance of Common Stock to
ZGNA and ZBI and related transactions, unless in the opinion of its legal
counsel its fiduciary obligations require it to modify or withdraw such
recommendation.

CONDITIONS OF THE MERGER

         The respective obligation of the parties to effect the Merger are
subject to the satisfaction or waiver prior to or upon the Closing Date of
certain conditions, including: (1) the absence of any injunction or order of any
nature directing that the contemplated transaction not be completed; (2) the
approval of the Merger Agreement by a the requisite holders of Common Stock; (3)
the appointment of Volker Wypyszyk to the office of President and Co-Chief
Executive Officer and election to the Board, effective as of the Closing Date;
(4) reconstitution of the Board in accordance with the Governance Agreement,
effective as of the Closing; (5) the absence of any material adverse
developments in the business of Hauser or its subsidiaries or the Contributed
Subsidiaries; (6) the

                                       18
<PAGE>

respective lenders; (7) the receipt of certain consents, approvals and
authorizations necessary for Hauser and the Contributed Subsidiaries to execute,
deliver and perform the Merger Agreement and to be able to lawfully conduct
business; (8) the expiration or termination of all waiting periods under the
Hart-Scott-Rodino Antitrust Improvement Act of 1976, as amended (the "HSR
ACT"); (9) the listing of the proposed stock issuance to ZGNA and ZBI on NASDAQ
or other exchange; (10) the availability of employees responsible for at least
75% of all sales of products for the Contributed Subsidiaries in the 90 days
prior to the date of the Merger Agreement to work in substantially the same
capacity for the surviving corporations after the Closing Date and not more than
25% of such individuals having stated in writing to ZGNA that they intend to
stop working for the Contributed Subsidiaries in such role; (11) the
availability of purchasing agents responsible for at least 75% of all purchases
of botanical raw materials of the Contributed Subsidiaries in the 90 days prior
to the date of the Merger Agreement to work in substantially the same capacity
for the surviving corporations after the Closing Date if offered a comparable
salary and compensation and benefit arrangements and not more than 25% of such
individuals having stated in writing to ZGNA that they intend to stop working
for the Contributed Subsidiaries in such role; and (12) the termination of an
exclusive distributorship agreement of ZBI without further liability to ZBI or
the Contributed Subsidiaries, including the restrictions on the ability to
engage in business contained therein.

         Other than approval of the Merger Agreement by Hauser shareholders 
and the expiration of certain waiting periods under the HSR Act, 
substantially all of the conditions to the Merger may be waived, without the 
approval of the Hauser shareholders. Under the HSR Act and the regulations 
promulgated thereunder, the Merger may not be consummated until notifications 
have been given and certain information has been furnished to the Federal 
Trade Commission (the "FTC") and the Antitrust Division of the Department of 
Justice (the "ANTITRUST DIVISION") and the applicable waiting period has 
expired or been terminated. Notwithstanding the termination of the waiting 
period, at any time before or after consummation of the Merger, the FTC, the 
Antitrust Division or any state entity could seek to enjoin the Merger, among 
other things, under federal or state antitrust laws.

TERMINATION

         The Merger Agreement may be terminated and the Merger may be abandoned
at any time prior to the Closing Date, notwithstanding any requisite approval of
the Merger Agreement and the Merger by the shareholders of Hauser: (1) by mutual
written consent of Hauser and ZGNA; (2) by either Hauser or ZGNA if either (a)
the Closing does not occur on or before May 31, 1999, unless extended by mutual
consent of the parties by 45 days; or (b) any governmental entity threatens to
or issues an order, decree or ruling or takes other action restraining,
enjoining or otherwise prohibiting any of the transactions contemplated by the
Merger Agreement; or (3) by ZGNA if the Board withdraws or modifies its
recommendation that the Merger Agreement be approved by the shareholders.
However, neither party may terminate the Merger Agreement whose failure to
perform any of its obligations under the Merger Agreement results in the failure
of the Closing by May 31, 1999.

         If the Merger Agreement is terminated in accordance with these
provisions of the Merger Agreement, no party will have any liability to any
other party to the Merger Agreement, except for any intentional breach or
misrepresentation of the terms of the Merger Agreement, for the destruction or
return of confidential information disclosed to or obtained by a party in
connection with the Merger, and for the continuing obligations of the parties to
maintain such confidential information in strict confidence following any
termination of the Merger Agreement.

         With the exception of certain covenants in the Merger Agreement, the
Merger Agreement will terminate and be void and have no effect upon termination
in accordance with its terms.

SURVIVAL OF REPRESENTATIONS AND WARRANTIES

         The representations and warranties made by the parties as to compliance
with applicable environmental laws and regulations and the filing of all tax
returns and payment of all required taxes, and any third party claims arising
out of misrepresentation of any of the representations or warranties made by the
parties in the Merger

                                       19
<PAGE>

Agreement, shall survive the Closing and remain in full force and effect for a
period of 24 months following the Closing Date. The representations and
warranties made by Hauser as to manufacturing capacity shall terminate as of the
Closing. All other representations and warranties in the Merger Agreement or the
agreements entered into in connection with the Merger Agreement shall survive
the Closing and remain in full force and effect for a period of 18 months
following the Closing Date. All covenants and agreements in the Merger Agreement
shall survive the Closing and remain in full force and effect for a period of 60
days after the expiration of the applicable statute of limitations (including
any extensions thereof). In addition, the subscription right granted pursuant to
the Merger Agreement will terminate upon the Closing Date or, if the Merger
Agreement is terminated, seven months after the date of the Merger Agreement.

BREAK-UP FEE

         The Merger Agreement provides for the payment of a break-up fee in 
the event: (1) Hauser shareholders do not approve the Merger Agreement; or 
(2) the Board withdraws, modifies or amends its recommendation that the 
Merger Agreement be approved by Hauser shareholders. If either of these 
events occurs, Hauser will be required to pay all of the reasonable 
out-of-pocket expenses ZGNA incurred in connection with the transactions 
contemplated by the Merger Agreement, including fees of counsel and financial 
advisors, up to $500,000. In addition, if Hauser within 12 months of a 
termination of the Merger Agreement under the circumstances described above 
sells a number of shares of Common Stock equal to 49% or more of the issued 
and outstanding shares of Common Stock in a sale of securities, merger or 
reorganization, or sells all or substantially all of its assets, Hauser will 
be required to pay to ZGNA $1,500,000 as a termination fee. If Hauser fails 
to promptly pay a break-up fee or termination fee and ZGNA is required to 
bring an action to obtain payment, Hauser will be required to pay ZGNA's 
costs and expenses, including attorneys' fees, plus interest, incurred by 
ZGNA in such action. In addition, if ZGNA exercises its option under the 
Agreement for Option to Acquire Common Stock of Hauser (the "OPTION 
AGREEMENT"), it agrees to return to Hauser any profit ZGNA makes on the 
exercise of the option, up to the amount of the termination fee received by 
it. See "CERTAIN ANCILLARY AGREEMENTS" below.

INDEMNIFICATION; DIRECTORS AND OFFICERS INSURANCE

         From and after the Closing Date, the Merger Agreement provides for the
indemnification by Hauser of ZGNA and by ZGNA of Hauser, and their respective
officers, directors and affiliates, from and against any liabilities, costs,
expenses, judgments, fines, losses, claims, damages and amounts paid in
settlement arising from or in connection with (1) any inaccuracy in any
representation or the breach of any warranty of the parties under the Merger
Agreement or an Ancillary Agreement; and (2) the failure of the parties to
perform or observe any term, provision, covenant or agreement to be performed or
observed pursuant to an Ancillary Agreement. Indemnification is only available
for a breach of a representation, however, to the extent the aggregate amount
subject to indemnification exceeds $750,000 and the maximum aggregate liability
for indemnification shall not exceed $15 million. No party is entitled to
indemnification for matters for which that party had knowledge at or prior to
Closing by reason of written notice in a supplemented disclosure schedule or an
officer's certificate at or prior to Closing and, if the closing conditions were
not met by reason of the matters disclosed, that party waived its right not to
close. This exception does not apply, however, if the other party made a knowing
misrepresentation about the matter at the date of the Merger Agreement, unless
Hauser or ZGNA had the explicit right under the Merger Agreement to notify the
other party about the matter at or prior to Closing and modify the corresponding
disclosures.

         In addition, from and after the Effective Date, persons who become
directors, officers or employees of Hauser will be entitled to indemnification,
subject to certain limitations, under the Bylaws and Articles of Incorporation
of Hauser, as may be amended from time to time in accordance with applicable
law. All rights to indemnification, and all limitations thereto, in favor of a
director, officer or employee of the Contributed Subsidiaries as provided in the
respective bylaws and certificate of incorporation of the Contributed
Subsidiaries in effect on the date of the Merger Agreement shall continue in
full force and effect with respect to directors, officers and employees of the
surviving corporations.

         The Merger Agreement also provides that all insurance policies of
Hauser, including directors and

                                       20
<PAGE>

officers liability insurance, shall not be terminated or reduced as a result 
of the Merger.

WAIVER OR AMENDMENT

   

         At any time prior to the Closing Date, the parties may change or modify
the Merger Agreement, or waive the observance of any term, upon written notice
signed by the parties. After shareholder approval of the Merger and issuance of
Common Stock to ZGNA and ZBI, the parties may terminate or amend the Merger
Agreement and the Ancillary Agreements, or waive their provisions, as permitted
by applicable law. If the Merger Agreement is amended to materially change the
terms of the transaction after the shareholder vote has been taken, Hauser will
solicit shareholders to vote on the amended agreement.

    

                          CERTAIN ANCILLARY AGREEMENTS

         In addition to the Escrow Agreement described above under "THE MERGER
AGREEMENT" and the Governance Agreement described below under "MANAGEMENT AFTER
THE MERGER", the parties entered into, or agreed to enter into at or prior to
the Closing Date, several other Ancillary Agreements. Each of these agreements
is summarized below.

INVENTORY PURCHASE AGREEMENT

   

         In connection with the Merger Agreement, Hauser executed an Inventory
Purchase Agreement (the "INVENTORY PURCHASE AGREEMENT") with ZGNA which is
intended to provide interim financing for Hauser and gives Hauser the right, at
its election, to sell its inventory to ZGNA in order to obtain cash. Under the
agreement, Hauser sold ZGNA raw material and finished goods inventory for a
total of $3,000,000. In addition, Hauser may subsequently, at its discretion,
require ZGNA to purchase an additional amount of its raw material inventory,
substantially similar to the purchased inventory, or finished product inventory,
acceptable to ZGNA in its reasonable discretion, of a value of up to $1,000,000
per month to an aggregate of $3,000,000. The purchase price for the inventory is
the lower of cost or market. Hauser agreed to use the proceeds from the sale of
the inventory in accordance with its cash flow projections for the five-month
period after the initial inventory purchase.

    

         At any time, Hauser may require ZGNA to resell to Hauser all or any
portion of the inventory purchased by ZGNA under the Inventory Purchase
Agreement at the same price at which ZGNA purchased the inventory and require
ZGNA, in its reasonable discretion, to purchase substantially similar raw
material and finished product inventory, having a value equivalent to the
repurchased inventory.

         On the Closing Date of the Merger, Hauser has an option to repurchase
all inventory purchased by ZGNA under the agreement at the same prices at which
ZGNA purchased the inventory. If the Merger Agreement terminates, Hauser has 45
days after the termination to repurchase all or any portion of the inventory.

AGREEMENT FOR OPTION TO ACQUIRE COMMON STOCK OF HAUSER

         Contemporaneously with the Merger Agreement, Hauser and ZGNA entered
into the Option Agreement. See "THE MERGER AGREEMENT - Break-Up Fee". The Option
Agreement grants ZGNA the option to purchase up to 2,000,000 shares of Common
Stock for $4.11 per share (the "OPTION"). ZGNA may exercise the Option in whole
or in part upon the occurrence of an "Exercise Event," which consists of (1) the
recommendation by Hauser that its shareholders approve any merger, business
combination, sale of all or substantially all of its assets, or the issuance and
sale of shares representing more than 20% of its outstanding stock, other than
the Merger; (2) the beneficial ownership, or the right to acquire beneficial
ownership, by a person or group other than, or not including, ZGNA or its
affiliates or associates of 20% or more of the voting power of Hauser; or (3) a
merger or consolidation, or sale of substantially all the assets of Hauser, with
any person other than ZGNA or its affiliates or associates. ZGNA may not,
however, exercise the Option to acquire 20% or more of the Common Stock, or
exercise the Option in any other manner that would require the approval of
Hauser's

                                       21

<PAGE>

shareholders under Rule 4310H of the National Association of Securities 
Dealers, Inc.

         The Option terminates: (1) on the Effective Date of the Merger; (2) on
the date the Merger Agreement is terminated, if terminated by reason of the
failure to receive the credit facility contemplated by the Merger Agreement; or
(3) nine months after the date the Merger Agreement is terminated, if terminated
for any other reason. In addition, if the Board approves a transaction involving
a merger or other consolidation with any other corporation or entity which is
not an affiliate of Hauser, or sale of all or substantially all its assets as
part of a plan of liquidation, the Board may require the holder of the Option to
exercise the Option simultaneously with the consummation of such merger,
consolidation or sale. If the holder does not exercise the Option in such case,
the Option will terminate on the business day preceding the closing of such
merger, consolidation or sale.

         In lieu of exercising the Option, ZGNA may elect to receive a payment
equal to the difference between (1) the market price (as defined in the Option
Agreement) of the Common Stock multiplied by the number of shares underlying the
Option for which payment is being elected, and (2) the exercise price of such
Option shares, payable by Hauser to the holder of the Option in shares of Common
Stock valued at the market price on the exercise date.

REGISTRATION RIGHTS AGREEMENT

         In connection with the Merger Agreement and the Option Agreement, 
Hauser, ZGNA and ZBI entered into a Registration Rights Agreement (the 
"REGISTRATION RIGHTS AGREEMENT") which provides ZGNA, ZBI or their 
transferees certain demand and piggyback registration rights in connection 
with the Common Stock. Subject to certain limitations, the holders of the 
registration rights have the right to request two demand registrations, 
provided the anticipated aggregate public offering price for the shares to be 
sold pursuant to such request exceeds $10,000,000. In addition, the holders 
have unlimited piggyback registration rights.

         With certain limited exceptions, Hauser bears all expenses of
registration, qualification or compliance and ZGNA and ZBI or their transferees
bear all selling expenses, including underwriting discounts, selling commissions
and all fees and disbursements of counsel for such holders.

         The Registration Rights Agreement provides for Hauser's indemnification
of the holders of the registration rights, including indemnification for
violations of the Securities Act.

         Hauser is not obligated to effect a registration of securities under
the Registration Rights Agreement if in the opinion of counsel to Hauser, all of
the Registrable Securities a holder desires to sell may be sold in any 90-day
period pursuant to Rule 144 issued under the Securities Act (without giving
effect to Rule 144(k)).

AGREEMENT FOR OPTION TO ACQUIRE POWDERS BUSINESS FROM ZBI

         Effective as of the Closing Date, Hauser and ZGNA have agreed to 
enter into an Agreement for Option to Acquire Powders Business from ZBI (the 
"POWDERS OPTION AGREEMENT") which grants Hauser the right to purchase the 
powders business of ZBI, including without limitation all assets related 
thereto and all associated liabilities, other than the shares of capital 
stock of Hauser held by ZBI (the "POWDERS OPTION"). The business of ZBI is 
primarily purchasing botanical raw materials throughout the world and 
converting the botanical raw materials, through a milling process, into 
powder at its facility in Long Beach, California. The powders are sold by ZBI 
to manufacturers of dietary supplements. The assets of ZBI consist primarily 
of inventory, receivables and fixed assets used in the production of the 
powders.

   

         ZGNA is not willing to sell the powders business of ZBI at this time
because it expects that, within the next 12 months, modifications will be made
in the manufacturing process of the powders business, which, at least in the
short term, ZGNA believes will provide a competitive advantage. ZGNA will not
agree to establish a value for the powders business until the earlier of the
modifications being completed or the exercise date for the Powders Option.

    

                                       22
<PAGE>

         At the request of Hauser and in lieu of the exercise of the Powders
Option, ZBI agrees to make commercially reasonable efforts to sell the capital
stock of ZBI to Hauser (after distribution of the shares of Hauser capital stock
held by ZBI) provided that there is not at such time, and will not be, any
adverse tax consequences to ZBI or ZGNA from the sale of ZBI stock instead of
assets to Hauser.

         Hauser may exercise the Powders Option, in whole only, at any time
after 12 months from the date of the Powders Option Agreement but not later than
two years after the date of the Powders Option Agreement. Upon exercise of the
Powders Option, Hauser and ZBI will enter into a purchase agreement containing
substantially the same representations and warranties, covenants and conditions
concerning ZBI as in the Merger Agreement, and substantially similar
indemnification provisions of ZBI as of ZGNA under the Merger Agreement.

         The purchase price for the powders business shall be equal to the fair
market value of the powder business on the exercise date as determined by Hauser
and ZBI. Hauser can pay the purchase price in cash or in shares of Common Stock
with a market price equal to the purchase price of the powders business, or a
combination thereof.

         ZBI has agreed that during the term of the Powders Option Agreement it
(a) will not change its capitalization or debt structure in a manner that would
frustrate the intent of the Powders Option Agreement, (b) will use commercially
reasonable efforts to conduct the powders business in the ordinary course and
preserve the powders business intact, and (c) not solicit or negotiate for the
sale of the powders business or the capital stock of ZBI with any person other
than Hauser.

         THE SHAREHOLDERS OF HAUSER ARE NOT VOTING UPON OR APPROVING HAUSER'S
EXERCISE OF THE POWDERS OPTION. IF REQUIRED BY APPLICABLE LAW OR THE APPLICABLE
RULES OF THE NASDAQ NATIONAL MARKET SYSTEM OR AN EXCHANGE ON WHICH THE COMMON
STOCK IS LISTED FOR TRADING, SUCH EXERCISE WILL BE SUBJECT TO A SEPARATE VOTE IF
AND WHEN HAUSER EXERCISES THE POWDERS OPTION.

AGREEMENT REGARDING EMPLOYEES

         Pursuant to the Merger Agreement, Hauser will execute and deliver an
Agreement Regarding Employees (the "EMPLOYEE AGREEMENT") with ZBI, effective as
of the Closing Date, for an initial term of two years. The Employee Agreement
provides that certain employees of ZBI who provide sales and marketing services
to ZBI and to Hauser shall be, while performing services for ZBI, employees
solely of ZBI and under ZBI's control and ZBI shall be responsible for the
payment of compensation for services rendered on its behalf. When performing
services for Hauser, each such employee shall be solely an employee of Hauser
and under Hauser's control and Hauser shall be responsible for the payment of
compensation for services rendered on its behalf. ZBI and Hauser further agreed
to use their best efforts to ensure that no employee under the Employee
Agreement holds himself out as an employee, representative or agent of ZBI when
performing services for Hauser, or of Hauser when performing services for ZBI,
as the case may be. Hauser and ZBI agree not to object to the employee spending
one half his or her normal working time in the active employment of the other.

         Each party agrees to indemnify the other party against (i) any claims
by any third party resulting from actions of an employee while such employee is
conducting the business of the party, and (ii) any claims by any employee
resulting from any actions of the party while such employee is providing
services for the party.

         Upon termination of the Employee Agreement, ZBI and its affiliates
(except Hauser, if considered an affiliate of ZBI) will no longer seek to employ
the employees covered under the Employee Agreement.

THE SOURCING AGENCY AGREEMENT

         The botanical raw materials sourcing personnel of ZBE and Wilcox
currently provide sourcing for ZBI. Hauser will execute a Sourcing Agency
Agreement (the "SOURCING AGREEMENT") with ZBI effective as of the Closing Date
relating to the purchase of certain botanical raw materials for use in the
manufacturing activities of ZBI. Under the Sourcing Agreement, Hauser will act
as ZBI's exclusive sourcing agent for ZBI's botanical raw

                                       23
<PAGE>

materials requirements and will use its best efforts to obtain offers from
sources to sell to ZBI the requested botanical raw materials.

         If Hauser purchases botanical raw materials for ZBI, ZBI will pay
Hauser a commission upon delivery of the botanical raw materials to ZBI. For the
first full six months after the effective date of the Sourcing Agreement, the
assumed commission rate will be $0.05 per kilogram of botanical raw materials
purchased by Hauser for ZBI. Thereafter, the assumed commission rate will be
adjusted based on Hauser's actual purchasing costs and the actual weight of the
botanical raw materials purchased by Hauser for ZBI during the initial period
relative to the weight of the botanical raw materials purchased for Hauser's own
purposes. For each successive six calendar month period, the assumed commission
rate will be adjusted based on Hauser's purchasing costs and the weight of the
botanical raw materials purchased by Hauser for the preceding six-month period.

         The Sourcing Agreement arrangement will commence on the Closing Date of
the Merger and terminate (1) by either party upon three months written notice
prior to the end of any calendar year that is at least two years after the
effective date of the Sourcing Agreement, (2) by mutual consent of the parties,
(3) by Hauser upon 60 days prior written notice after receiving notice of a
change of control of ZBI; (4) by either party upon 30 days prior written notice
of a material uncured breach of the Sourcing Agreement, or (5) by either party
if the other party has made an assignment for the benefit of creditors, admitted
insolvency, instituted voluntary proceedings in bankruptcy, or involuntary
proceedings in bankruptcy or insolvency have begun against the other party and
have not been dismissed within 60 days, or an application that has been made for
receivership with respect to the other party or any material part of its assets
or business that has been granted or not been dismissed within 60 days.

CREDIT FACILITY

         Hauser has obtained a commitment letter from the Bank subject to the
closing of the Merger. The commitment letter provides two credit facilities to
Hauser up to an aggregate amount of $45,000,000, to be guaranteed by each of its
subsidiaries: a revolving line of credit up to $35,000,000 for general working
capital maturing two years after the loan closing, and a $10,000,000
non-revolving term commitment for financing the acquisition of fixed assets with
a draw down period of two years and a maturity date five years following the
loan closing (collectively, the "CREDIT FACILITY").

         The Credit Facility includes a $1,000,000 sublimit for the issuance of
commercial letters of credit up to 150 days in term. The advance rates for the
revolving facility are 80% of eligible accounts receivable and 50% of eligible
inventory (and up to 65% of eligible inventory during the seasonal peak
borrowing period of September through December). Inventory collateral for loan
purposes may not exceed $15,000,000, except during the September through
December period when it may not exceed $25,000,000.

         For the revolving loan, the interest rate is the Bank's prime rate
minus .75% or the Bank's quoted LIBOR plus 1.5% per annum. For the term loan
fixed asset facility, the interest rate is the Bank's prime rate minus .5%, or
the Bank's quoted LIBOR plus 1.75% per annum, or on an unspecified fixed rate
basis. A commitment fee will be charged of .25% per annum on the unused portion
of the term loan fixed asset commitment.

         A first lien will be granted to the Bank on all the assets of Hauser
and its subsidiaries (including the Contributed Subsidiaries). The definitive
agreements for the Credit Facility will contain certain affirmative and negative
covenants, including certain financial covenants.

         Hauser's subsidiaries will guarantee the debt of Hauser, and Hauser may
guarantee the debt of its subsidiaries, in connection with the proposed Credit
Facilities. The Bank commitment prohibits Hauser or its subsidiaries from having
additional indebtedness.

         The Bank commitment requires that Mr. Wypyszyk be Co-Chief Executive
Officer of Hauser with key management responsibilities acceptable to the Bank.

                                       24
<PAGE>

         The Bank commitment is subject to the closing of the Merger, certain
representations and warranties and covenants of Hauser, no material adverse
changes in the business, assets (except for the charge related to the paclitaxel
business), financial condition, income or prospects of the parties, no material
misstatements in or omissions from the materials furnished to the Bank by the
parties, no material adverse change in government regulation or policy governing
the parties, and the absence of any litigation or other action pending or
threatened relating to the facilities. Hauser must also execute and deliver
definitive loan documents in form and substance satisfactory to the Bank,
including such representations, warranties, conditions, covenants and events of
default as the Bank deems appropriate.

         The execution of definitive agreements relating to the Credit Facility
is a condition to the closing of the transactions contemplated by the Merger
Agreement.

         Based on the financial projections of Hauser immediately after the
Closing, Hauser will be in compliance with the covenants specified in the
commitment letter and will have sufficient availability to pay in full its
current credit facility with the First National Bank of Boston (which facility
will terminate), the debt representing the Contributed Subsidiaries' obligations
to ZGNA's current principal lender. There is no assurance the Bank will provide
the credit facility described above, that if provided, the terms will be exactly
as described above, or that the maximum amount of credit availability will
exist.

         THE BOARD UNANIMOUSLY RECOMMENDS A VOTE FOR THE APPROVAL OF THE MERGER
AGREEMENT AND THE ISSUANCE OF COMMON STOCK TO ZGNA AND ZBI.

                              DESCRIPTION OF HAUSER

         Hauser was incorporated under the laws of the State of Colorado in
December 1996, under the name Hauser, Inc. as the successor company to a
Delaware corporation (Hauser Chemical Research, Inc.) formed in 1983.

         Hauser develops, manufactures and markets superior natural products and
offers product development, research, testing and other technical services.

         Hauser operates three business units: Natural Products, Technical 
Services and Pharmaceuticals. Under the Natural Products unit, Hauser 
develops, manufactures and markets special products from natural sources 
under the NaturEnhance-Registered Trademark- trademark. It is a premier 
supplier of bulk natural ingredients to dietary supplement and food 
ingredient suppliers in the United States. Hauser's proprietary extraction 
and purification processes enable the production of bulk natural extracts at 
a high quality, yield and concentration.

         Hauser's Technical Services business unit offers innovative technical
services to a diverse customer base and has earned a national reputation for
scientific and problem-solving excellence. It is comprised of Hauser
Laboratories in Boulder, CO, and Shuster Laboratories in Quincy, MA and Smyrna,
GA. The expertise of the Technical Services business unit in natural product
isolation, pharmaceutical development, and formulation of food products and
nutraceuticals supports Hauser's other business units.

   

         Hauser's pharmaceutical products include natural and custom synthesized
compounds used in a variety of drug development and commercial applications.
This business unit is built on substantial experience and capabilities
manufacturing under Food and Drug Administration and Good Manufacturing
Practices. In December 1998, Hauser announced its intention to terminate its
paclitaxel business to focus its corporate resources on its Natural Products and
Technical Services business units. A corresponding one-time accounting charge of
$25.6 million was recorded in the quarter ended January 31, 1999. In February
1999, Hauser signed a contract for the sale of the majority of its paclitaxel
inventory as part of the planned closure of its paclitaxel business. The
purchase agreement will gross approximately $9.5 million to Hauser over the next
six to nine months. Net proceeds (as defined below) from this agreement are
expected to be approximately $2.5 million. In connection with the termination of
the paclitaxel business, Hauser intends to negotiate settlements of its yew tree
cultivation agreements and a termination of a multi-year non-exclusive agreement
to supply paclitaxel to a customer. The expected costs of such settlements and
terminations are included in the $25.6 million write off taken in the quarter
ended January 31, 1999.

    

         Hauser is a "CUSTOMER CONNECTED" company whose customer support
utilizes Hauser's technical and regulatory expertise to help ensure the success
of each project. "CUSTOMER CONNECTED", a management strategy implemented at
Hauser, defines a company that totally focuses on customers' needs, owns and
solves customers' problems, builds strong customer/company relationships at all
levels, and capitalizes on customer problems as company opportunities.

         In January 1999, Hauser was served with a Demand for Arbitration by a
supplier of raw materials. The Demand alleges that Hauser has breached its
contract by failing to pay for certain raw materials. Hauser believes that the
claims are unfounded, has retained legal counsel and intends to vigorously
defend its position in arbitration.

                   DESCRIPTION OF THE CONTRIBUTED SUBSIDIARIES
ZBE

   

         ZBE, as a distributor, has sold bulk standardized and non-standardized
nutraceutical extracts to manufacturers of dietary supplements since 1990.
Standardized extracts represent approximately 80% of the current annual sales of
ZBE. ZBE, which initially operated as a division of ZBI, was incorporated in
August 1998.

    
   

         The standardized extracts sold by ZBE contain specified concentrations
of the active ingredients and marker compounds of the particular botanical raw
materials being extracted. The standardized extracts are primarily sold by ZBE
to manufacturers of dietary supplements located in the United States. The
primary standardized nutraceutical extracts sold by ZBE are St. John's Wort,
Kava Kava, Gingko and Saw Palmetto. Since 1990, a substantial portion of the
standardized extracts sold by ZBE have been primarily manufactured by two
subsidiaries of Martin Bauer. See "RISK FACTORS -- Nutraceutical Extracts --
Suppliers and Customers." ZBE believes that it supplied approximately 10% of the
standardized nutraceutical extracts sold to manufacturers of dietary supplements
in 1998.

    

         Non-standardized nutraceutical extracts sold by ZBE contain the levels
of active ingredients that are present in the botanical raw materials being
extracted. Non-standardized nutraceutical extracts are primarily exported by
ZBE. Non-standardized nutraceutical extracts are primarily manufactured for ZBE
by a contract manufacturer located in the United States.

   

         ZBE sells nutraceutical extracts through its sales force consisting of
eleven employees, nine in California, one in Maryland and one in Florida. Four
of the eleven sales employees also provide customer support.

    
   

         ZBE sells standardized nutraceutical extracts to more than 180
customers and no customer accounts for more than 17% of the annual standardized
nutraceutical extracts sales. ZBE sells non-standardized nutraceutical extracts
to more than 90 customers. Currently, one customer accounts for approximately
half of the nonstandardized extract annual sales.

    

         Major competitors of ZBE in the sale of nutraceutical extracts to
manufacturers of dietary supplements are Indena (Italy), Martin Bauer (Germany),
Euromed (Spain) and PureWorld Botanicals (United States), all of whom
manufacture the extracts. In addition, there are a number of smaller
competitors. ZBE competes on the basis of quality, service, product development
and price.

ZETAPHARM

         ZetaPharm, which was founded in 1976, is a distributor of bulk fine
chemicals, excipients and active ingredients used in the manufacture of generic
pharmaceuticals.

         Fine chemicals sold by ZetaPharm include bulk vitamins, nutritional
supplements, over-the-counter pharmaceutical ingredients and food additives.
Such products are sold to manufacturers and processors of health food,
pharmaceuticals, food and beverages.

         ZetaPharm is the exclusive distributor in the United States for the
excipients line of Blanver Farmoquimica, Brazil, a leading manufacturer of
excipients. Excipients are derived from cellulose and are used as binders in the
production of tablets. Excipients are also used as ingredients in the slow
release process of tablets and capsules. Excipients are sold to manufacturers of
vitamins and dietary supplements.

   

         ZetaPharm distributes bulk generic active ingredients manufactured by
Zambon, which is located in Italy, and by China Chemical Synthesis, Inc., which
is located in Taiwan. Generic active ingredients are sold by ZetaPharm to
pharmaceutical manufacturers for use in human and veterinary applications. The
sale of generic active ingredients purchased from Cilag, located in Switzerland,
represented 54% and 40% of ZetaPharm total

                                       29
<PAGE>

sales in the fiscal year ended March 31, 1998 and the ten months ended January
31, 1999, respectively. In 1998, ZetaPharm was advised that Cilag had elected to
sell its products directly. As a result, ZetaPharm expects that the revenue from
the sale of generic active ingredients will be insignificant in the fiscal year
ended March 31, 2000. ZetaPharm is actively seeking additional sources of
generic active ingredients to distribute.

    

         ZetaPharm primarily imports the products that it sells. ZetaPharm
suppliers are primarily located in Europe, China, India, and South America.

         In the sale of its products, ZetaPharm competes with major
pharmaceutical companies, major manufacturers of food supplements and excipients
and other distributors of such products. ZetaPharm competes on the basis of
service, product quality and price.

   

         ZetaPharm has twenty one employees. Ten are engaged in sales and six
are engaged in customer service. ZetaPharm's principal office is located in New
York, and it has offices in Florida, Missouri, California, New Jersey, and
Oregon.

    

WILCOX

         Wilcox, which does business as Wilcox Natural Products, is a leading
supplier to customers in the United States, Asia and Europe of botanical raw
materials wild gathered in the United States and cultivated botanical raw
materials. Wilcox has been engaged in purchasing botanical raw materials since
1900. Wilcox was purchased by ZGNA in 1982.

         The primary botanical raw materials products sold by Wilcox are saw
palmetto berries, echinacea purpurea, echinacea angustifolia, goldenseal,
American wild ginseng, black cohosh, passion flower, slippery elm bark, witch
hazel and Missouri snake root.

         The botanical raw materials sold by Wilcox are used in the manufacture
of nutraceutical extracts or the production of botanical powders, both of which
are sold to manufacturers of dietary supplements. In 1998, approximately 38% of
Wilcox sales were made to ZBI. The next largest customer accounted for 16% of
1998 sales. Approximately 60% of Wilcox annual sales are made pursuant to annual
contracts with customers.

         Wilcox purchases the wild gathered botanical raw materials, which are
acquired in the United States, at buying stations located in North Carolina,
Florida, Kentucky and Missouri. Wilcox purchases the botanical raw materials
from the collectors of the botanical raw materials. Since more than 80% of the
botanical raw materials purchased by Wilcox is wild gathered, production is
dependent on the price of the product, growing conditions and available habitat.
Wilcox has approximately 1,000 acres of botanical raw materials under contract
cultivation in the United States, Canada and Costa Rica, of which approximately
300 acres are leased to Wilcox. Wilcox leases four acres in Boone, North
Carolina, where it conducts botanical cultivation experimentation.

         Wilcox is the largest purchaser of botanical raw materials wild 
gathered in the United States. The major competitors of Wilcox for botanical 
raw materials wild gathered in the United States are M.F. Neal and Plantation 
Botanicals Inc.

   

         Wilcox has approximately twenty seven employees. Seven are engaged 
in purchasing of botanical raw materials; two are engaged in the sale of 
botanical raw materials; two are engaged in cultivation; and the balance are 
engaged in processing, warehousing and administration.

               SELECTED HISTORICAL FINANCIAL DATA OF HAUSER, INC.

   

         The following is a summary of selected historical financial data 
which Hauser believes highlights trends in its financial condition and 
results of operations. The data is derived from the audited consolidated 
financial statements and is as of and for Hauser's fiscal years ended April 
30, 1994, 1995, 1996, 1997 and 1998. This information should be read in 
conjunction with the audited consolidated financial statements of Hauser, 
including the notes thereto, appearing elsewhere in this Proxy Statement. See 
"Available Information," and Appendix D. In the fiscal year ended April 30, 
1994, 88% of Hauser's revenues were derived from the sale of bulk paclitaxel 
to Bristol-Myers Squibb Company ("Bristol"). Hauser had a three year supply 
contract that commenced in 1991. During the fiscal year ended April 30, 1994, 
Bristol decided not to extend the supply agreement, and so Hauser's revenues 
and profits declined significantly beginning in fiscal 1995. Since then, 
Hauser has been rebuilding its revenue and earnings base through growth in 
its Natural Ingredients and Technical Services business units.

                            CONTRIBUTED SUBSIDIARIES

                      MANAGEMENT'S DISCUSSION AND ANALYSIS

                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

RESULTS OF OPERATIONS FOR THE FISCAL YEARS ENDED MARCH 31, 1998, 1997 AND 1996

NET SALES. Net sales increased 38% from $73,140,247 in 1997 to $101,126,620 in
1998. This increase is due to increases in extract and bulk generic active
ingredient sales. The increase in sales of 19% from 1996 to 1997 can also be
attributed to increases in extract and bulk generic active ingredient sales,
offset by a decrease in sales of botanical raw materials.

   

In 1998, ZetaPharm was advised that its principal supplier of generic active
ingredients had elected to sell its products directly. The sale of generic
active ingredients represented 30% of sales in 1998 and are expected to
represent approximately 17% of sales in the fiscal year ending March 31, 1999.
Sales of generic active ingredients will be insignificant in the year ending
March 31, 2000.

    
   

GROSS PROFIT. Gross profit increased 55% from $10,855,108 in 1997 to $16,807,911
in 1998. As a percentage of net sales, gross profit increased from 15% in 1997
to 17% in 1998. During 1997, the market softened on one particular product and
the resulting sales of such product generated a loss of approximately $500,000.
No losses were incurred with respect to the sale of such product in 1998.

    

Gross profit decreased 6% from $11,580,524 in 1996 to $10,855,108 in 1997. As a
percentage of net sales, gross profit decreased from 19% in 1996 to 15% in 1997.
The deterioration in gross profit in absolute dollars as well as a margin
percentage is due primarily to sales of one product in 1996 at higher than
average margins, and sales of the same product in 1997 at a loss.

COMMISSION AND OTHER INCOME. Commission and other income decreased by 80% from
$1,389,012 in 1997 to $282,939 in 1998. Other income in 1997 included a reversal
of an environmental cleanup reserve in the amount of $805,282. During 1996,
commission and other income was insignificant.

   

OPERATING EXPENSES. Selling, general and administrative expenses ("SG&A"
expenses) rose from $6,855,444 in 1997 to $8,570,143 in 1998, a 25% increase,
and increased by 16% in 1997 from a level of $5,897,511 in 1996. As a percentage
of sales, SG&A expenses were 8%, 9% and 10% in 1998, 1997 and 1996,
respectively. The increase in SG&A expenses in absolute dollars is due to an
expansion in the businesses of the Contributed Subsidiaries, which required an
increase in sales personnel and marketing expenditures.

    
   

Management fee expenses rose from $429,007 in 1997 to $1,601,163 in 1998, a 273%
increase, and increased by 68% in 1997 from a level of $255,643 in 1996.
Historically, these expenses have been based on a structured fee. Beginning in
1998, management fees were charged based on a net funds employed formula,
derived from key balance sheet accounts.

    
   

INTEREST EXPENSE. Interest expense (net) rose from $1,127,371 in 1997 to
$1,190,689 in 1998, a 6% increase, and increased by 13% in 1997 from a level of
$997,422 in 1996. The increase from 1997 to 1998 is due to reduced interest
income attributable to amounts due from affiliates. The increase from 1996 to
1997 is due to higher debt levels in 1997 as compared to the prior year.

    
   

INCOME TAXES. The effective income tax rate during the years ended 1998, 1997
and 1996 were 42%, 32% and 23%, respectively. The effective rates differ from
the federal statutory rate due primarily to state income taxes and adjustments
to the valuation allowance on deferred tax assets.

RESULTS OF CONTINUING OPERATIONS FOR THE TEN MONTHS ENDED JANUARY 31, 1999
AND 1998

    
   

NET SALES. Net sales decreased 12% from $82,063,968 in 1998 to $71,881,579 in
1999. The decrease is attributed primarily to a decrease in sales of bulk
generic active ingredients, offset by an increase in the sale of botanical raw
materials. Sales of bulk generic active ingredients were 18% and 34% of sales
generated during the ten months ended January 31, 1999 and 1998, respectively.

    
   

GROSS PROFIT. Gross profit decreased 26% from $13,885,636 for the ten months
ended January 1998 to $10,293,937 for the ten months ended January 1999. As a
percentage of net sales, gross profit decreased from 17% in 1998 to 14% in 1999.

    
   

The decrease in gross profit from the prior year is due primarily to a reduction
in sales of bulk generic active ingredients. Additionally, margins achieved on
extract sales declined from 1998 to 1999. The reduction in extract margins is
due primarily to a reduction in margins generated on one product, which achieved
favorable margins in 1998 and significantly less favorable margins in 1999.
Sales of this product represented 9% and 16% of total sales generated during the
ten months ended January 1999 and 1998, respectively. Finally, sales to
affiliates have historically been made at margins comparable to margins
generated on sales to third parties. During 1999, it was contemplated that
Wilcox Drug Company, Inc. ("WILCOX") would be merged into Zuellig Botanicals,
Inc. ("ZBI"), and accordingly, all sales during the ten month period ended
January 31, 1999 were made to ZBI at cost. If such sales had been made at
margins comparable to historical margins, sales and gross profit would have been
increased by approximately $956,000.

    
   

OPERATING EXPENSES. SG&A expenses decreased 13% from $7,317,222 for the ten
months ended January 1998 to $6,361,221 for the ten months ended January 1999.
As a percentage of sales, SG&A expenses remained consistent at 9% of sales for
the ten months ended January 1998 and 1999.

    
   

Management fee expenses rose from $832,716 for the ten months ended January 1998
to $870,176 for the ten months ended January 1999, an increase of 5%. This
increase is due to increased net funds employed during the ten months ended
January 1999 as compared to the same period in the prior year.

    
   

INTEREST EXPENSE. Interest expense (net) rose from $987,838 for the ten months
ended January 1998 to $1,122,798 for the ten months ended January 1999, a 14%
increase. This increase is due to higher inventory levels being financed through
the line of credit in 1999.

    
   

INCOME TAXES. The effective income tax rate during the ten months ended January
31, 1999 and 1998 were 42% and 41%, respectively. The effective rates differ
from the federal statutory rate due primarily to state income taxes.

    

LIQUIDITY AND CAPITAL RESOURCES

   

The Contributed Subsidiaries' cash position at March 31, 1998 was $1,866,735
compared to $838,754 at March 31, 1997, an increase of $1,027,981. At January
31, 1999, the cash position decreased to $11,886, a decrease of $1,854,849 from
March 31, 1998. Net cash provided by operating activities was $10,231,951 for
the year ended March 31, 1998. Net income of $3,339,660, depreciation and
amortization of $240,329 and increases in accounts payable, accrued liabilities
and amounts due to affiliates of $11,155,215, were partially offset by an
increase in receivables of $2,504,231, increase in inventories of $1,148,731,
increase in prepaids, deposits on cultivation and other current assets of
$650,831, increase in deferred income taxes of $193,546 and gain on sale of
property of $5,914. Net cash used in operating activities was $12,131,907 for
the ten months ended January 31, 1999. Net income of $1,359,663, depreciation
and amortization of $175,058, an increase in amounts due to affiliates of
$1,258,599, and decreases in receivables of $2,200,514 and deposits on
cultivation projects of $31,460, were offset by increases in inventories of
$13,263,434 and prepaids and other current assets of $1,677,284, decreases in
accounts payable and accrued liabilities of $2,214,128 and gain on sale of
property of $2,355. Investing activities of $184,836 for the year ended March

of capital expenditures of $192,836 and 70,247, respectively. Net

cash used in financing activities of $9,019,134 for the year ended March 31,
1998 consists of net repayments under line of credit agreements of $8,800,746,
principal payments on long term debt of $55,000 and a decrease in bank overdraft
of $163,388. Net cash provided by financing activities of $10,327,900 for the
ten months ended January 31, 1999 consists of net borrowings under line of
credit agreements.

    
   

Short-term bank borrowings consist of a line of credit. During 1998, the
Contributed Subsidiaries, ZGNA and certain affiliates entered into various
credit agreements with a bank under which they may borrow up to $35,000,000
under a revolving credit agreement with an additional $3,000,000 available upon
approval by the bank, and up to $750,000 under a non-revolving line of credit
with a term repayment option through December 1, 1998 (the "1998 Credit
Agreements"). The amount outstanding under the Contributed Subsidiaries' 1998
Credit Agreements was $10,305,683 at March 31, 1998. All borrowings are
collateralized by receivables and inventories, and all borrowings are
cross-guaranteed by the Contributed Subsidiaries, ZGNA and affiliates
participating in the credit agreements.

    
   

During December 1998, the 1998 Credit Agreements were extended for eight days.
On December 8, 1998 the Contributed Subsidiaries, ZGNA and its affiliates
entered into various new credit agreements (the "1999 Credit Agreements") with a
bank under which they may borrow up to $38,000,000 under a revolving credit
agreement with an additional $6,500,000 available under a non-revolving loan
commitment. The 1999 Credit Agreements have a term repayment option through
April 30, 1999, with an option to extend the maturity date to July 31, 1999 at
the bank's discretion. Under the terms of the 1999 Credit Agreements, $1,500,000
is available for the issuance of letters of credit with a maximum term of 150
days.

    
   

The amount outstanding under the Contributed Subsidiaries' 1999 Credit
Agreements was $20,633,583 at January 31, 1999. The aggregate amount outstanding
under the 1999 Credit Agreements for ZGNA and its subsidiaries was $38,859,315
at January 31, 1999.

    
   

No significant capital expenditures are planned for the upcoming fiscal year.
Management believes that the Contributed Subsidiaries' current cash position,
the working capital generated from future operations and the ability to borrow
should be adequate to meet its financing requirements for current operations and
the foreseeable future.

    

SEASONALITY

Historically, the Contributed Subsidiaries' strongest selling season has been
the months of January through March. While the Contributed Subsidiaries purchase
inventory throughout the year, a substantial portion of the inventory
requirements are purchased during the harvest seasons of botanical raw
materials. This harvest season generally begins in August and concludes in
December. As a result of the seasonality, inventory and short term debt are
substantially higher in the second and third quarters.

YEAR 2000

The Year 2000 problem is the result of computer programs recognizing a date
using "00" as the year 1900 rather than the year 2000, which could result in
miscalculations or system failures. The Contributed Subsidiaries have undertaken
a thorough review of their current information technology ("IT") and non-IT
systems. This review is expected to be a continuing process. Based on this
review and the resulting changes that were implemented, the majority of the
Contributed Subsidiaries' hardware has now been upgraded to comply with Year
2000 requirements. The total cost for these upgrades is not expected to exceed
$75,000.

As another part of Year 2000-compliance review, the Contributed Subsidiaries
have also undertaken a logical process of updating or deleting software systems
known to have problems handling two-digit date information properly. The testing
and identification phase of the review of core applications supporting
accounting, human resources and manufacturing processes has now been completed.
Upgrade or replacement of these applications is expected to be completed in the
spring of 1999. The net cost of these upgrades is not expected to exceed
$100,000.

                                       37
<PAGE>

The Contributed Subsidiaries have also implemented a Year 2000 compliance
inquiry program with its current and potential major vendors and suppliers as to
both the status of their equipment and systems and any delays they anticipate in
supplying goods and services to the Contributes Subsidiaries. If a third party's
systems are not Year 2000 compliant, that problem will be addressed directly
with that third party.

Management recognizes that failure to meet all Year 2000 issues could result in
significant degradation of the Contributed Subsidiaries ability to provide
laboratory testing, to track and record manufacturing processes, invoice
customers and pay vendors. Management is addressing these issues directly,
aggressively pursuing upgrading all mission-critical systems.

   

Management foresees the likely internal "worst case scenario" to be limited in
scope, and could include a very small number of machines that may not handle
date data correctly. In this event, processing of data will be shifted to other
machines until repair or replacement can be accomplished. No significant
degradation of data collection or processing is anticipated.

    

If, because of unforeseen circumstances, installed hardware and software systems
cease to function on January 1, 2000, a disaster recovery contingency plan will
be activated to handle the emergency situation. The Contributed Subsidiaries
have established relationships with several computer system vendors who will
provide the necessary hardware and software to support the contingency plan.

                    UNAUDITED PRO FORMA FINANCIAL STATEMENTS

   

         The unaudited pro forma condensed combined financial data as of 
January 31, 1999 and for the twelve months ended April 30, 1998 and the nine 
months ended January 31, 1999 give effect to the Merger, accounted for under 
the "purchase" accounting method. The unaudited pro forma condensed combined 
financial data is based on the historical consolidated financial statements 
of Hauser and the historical combined financial statements of the Contributed 
Subsidiaries under the assumptions and adjustments set forth in the notes to 
such pro forma financial data.

    
   

         The unaudited pro forma condensed combined balance sheet data 
assumes that the Merger was consummated on January 31, 1999, and the 
unaudited pro forma condensed combined statements of operations data assumes 
that the Merger was consummated on May 1, 1997. The fiscal year of Hauser 
ends on April 30, and the fiscal year of the Contributed Subsidiaries ends on 
March 31. For purposes of presenting the unaudited pro forma condensed 
combined statements of operations data, the historical financial statements 
of Contributed Subsidiaries for the year ended March 31, 1998 were combined 
with the historical financial statements of Hauser for the year ended April 
30, 1998. The historical financial statements of Hauser for the nine months 
ended January 31, 1999 have been combined with the unaudited historical 
financial statements of the Contributed Subsidiaries for the nine months 
ended January 31, 1999.

    
   

         For the purposes of presenting the unaudited pro forma condensed 
combined balance sheet data, the tangible assets and liabilities of the 
Contributed Subsidiaries have been adjusted to their estimated fair market 
values and the excess purchase price has preliminarily been assigned to 
goodwill, which is being amortized over a 20-year period. The fair value of 
the Contributed Subsidiaries assets and liabilities is based on preliminary 
estimates and may change from those estimates due to changes in the fair 
value of tangible assets and liabilities at the date of the closing, the 
results of management's valuation of intangible assets other than goodwill 
acquired as part of the merger, and the impact of the Escrow Agreement (see 
"THE MERGER AGREEMENT - The Escrow Agreement"). Upon completion of the 
merger, management will perform a valuation of the fair value of the assets 
and liabilities and make an assessment of the impact of the escrow agreement 
in order to finalize the purchase accounting. The effect of the valuation and 
assessment is not expected to have a material effect on the pro forma 
combined financial statements included in this proxy. The unaudited pro forma 
condensed combined statements of operations data exclude any benefit that may 
result due to synergies that may be derived and elimination of duplicative 
efforts resulting from the acquisition of the Contributed Subsidiaries.

    
   

         The pro forma adjustments included herein are based on the available 
information and certain assumptions that management believes are reasonable 
and factually supportable. The adjustments for the costs related to the exit 
of the paclitaxel business have been included herein as the decision to exit 
the paclitaxel business is a direct result of Hauser's decision to enter into 
the Merger Agreement. These adjustments are described in more detail in the 
accompanying notes. The unaudited pro forma condensed combined financial 
statement data may not be indicative of the results that actually would have 
occurred if the acquisition of the Contributed Subsidiaries had been 
consummated on the dates indicated or which may be obtained in the future. 
The unaudited pro forma condensed combined financial statement data should be 
read in conjunction with the historical consolidated financial statements for 
Hauser and the historical combined financial statements of the Contributed 
Subsidiaries.

                             AS OF JANUARY 31, 1999

    
   

(1)      Reflects the estimated goodwill associated with the Merger computed as
         follows:

                   Total consideration                                  45,475,530
         Fair value of the excess of identifiable assets
         acquired over liabilities assumed by Hauser                  (12,005,831)
                                                                ------------------
                   Goodwill                                           $ 33,469,699
</TABLE>
    
   

         The total value of the common stock to be issued to ZGNA and ZBI of
         approximately $44,475,530 was determined based on the average closing
         price of Hauser's stock for three days prior and three days after the
         announcement of the Merger. Approximately 2,412,000 shares issued to
         shareholders of ZGNA and ZBI will be held in escrow pending Hauser's
         sale of the paclitaxel business. The shares are to be released from
         escrow and subsequently retired based upon the net proceeds realized
         from the sale of the paclitaxel business in excess of $3,000,000. Net
         proceeds has been defined to mean the cash proceeds from the sale of
         paclitaxel related assets realized by October 31, 1999, less (1) all
         cash costs incurred to complete production of the inventory into
         finished goods; (2) estimated costs to terminate cultivar contracts and
         (3) other cash costs incurred to exit the paclitaxel business. Hauser
         has entered into a bulk sales agreement for substantially all of its
         paclitaxel inventory under which gross proceeds would be approximately
         $9.5 million. Net proceeds as of the date of the agreement, after
         estimated costs to complete in-process paclitaxel inventory ($2
         million) and estimated costs to terminate its cultivar contracts ($5
         million) would be approximately $2.5 million resulting in no shares
         being released from escrow. The shares are to be released from escrow
         and subsequently retired at a rate of $3.50 per share (see "The Escrow
         Agreement"). The amount of shares are to be released from escrow will
         depend on the cash proceeds received from the sale of paclitaxel
         related intellectual property, the cost of terminating the cultivar
         contracts and the cost of processing the remaining paclitaxel
         inventory. The ultimate amount of goodwill will depend on the shares
         released from escrow (if any) and the fair value of the Contributed
         Subsidiaries assets and liabilities on the Effective Date of the
         Merger.
    
   
(2)      Reflects the new revolving and term credit facility entered into in
         conjunction with the Merger. Upon consummation of the Merger, Hauser
         will enter into two credit facilities for an aggregate amount of
         $45,000,000 to be guaranteed by each of its subsidiaries: a revolving
         line of credit up to $35,000,000 for general working capital purposes
         maturing two years after the loan closing, and a $10,000,000 non-
         revolving term commitment for financing the acquisition of fixed assets
         with a draw down period of two years and a maturity date of five years
         following the loan closing. The interest rate on the revolving credit
         facility is the Bank's prime rate minus 0.75% per annum or the Bank's
         quoted LIBOR rate plus 1.5% per annum. For the term loan fixed asset
         facility, the interest rate is the Bank's prime rate minus 0.5% per
         annum or the Bank's quoted LIBOR plus 1.75% per annum or on a specific
         fixed rate basis. The commitment fee for the credit facility arranged
         in connection with this transaction is 0.25% per annum on the unused
         portion of the $10.0 million fixed asset line. The commitment fee is
         paid quarterly in arrears. No adjustment is presented in the pro forma
         financial statements as the amount expected to be drawn on the line and
         the resulting commitment fee is not factually supportable.
    
   
(3)      Reflects the estimated merger related costs consisting principally of
         transaction costs for financial advisory fees, attorneys, accountants
         and financial printing related to the Merger.
    
   
(4)      Reflects the issuance of approximately 10,057,000 shares of Hauser's
         Common Stock to ZGNA and ZBI shareholders. This includes approximately
         2,412,000 shares held in escrow. The number of shares of Hauser's
         Common Stock that will ultimately be issued to ZGNA and ZBI is based on
         a formula defined in the Escrow Agreement (see "The Escrow Agreement").
         The shares are to be released from escrow and subsequently retired
         based upon the net proceeds realized from the sale of the paclitaxel
         business in excess of $3,000,000. Net proceeds has been defined to mean
         the cash proceeds from the sale of paclitaxel related

                                       42
<PAGE>

         assets realized by October 31, 1999, less (1) all cash costs incurred
         to complete production of the inventory into finished goods; (2)
         estimated costs to terminate cultivar contracts and (3) other cash
         costs incurred to exit the paclitaxel business. Hauser has entered into
         a bulk sales agreement for substantially all of its paclitaxel
         inventory under which gross proceeds would be approximately $9.5
         million. Net proceeds as of the date of the agreement, after estimated
         costs to complete in-process paclitaxel inventory ($2 million) and
         estimated costs to terminate its cultivar contracts ($5 million) would
         be approximately $2.5 million resulting in no shares being released
         from escrow. Because the cancellation of the shares held in escrow is
         not highly probable, Hauser has assumed that none of the shares will be
         retired and ZGNA and ZBI will own 49% of the outstanding Common Stock.
         If all escrow shares are returned to Hauser and canceled, pro forma
         equity and goodwill would be reduced by approximately $10,807,000.
    
   
(5)      In connection with the Merger Agreement, Hauser executed an inventory
         purchase agreement with ZGNA which is intended to provide interim
         financing for Hauser. Included in Deposits as of January 31, 1999, is
         $3 million received pursuant to this agreement. The purchase price for
         the inventory is the lower of cost or market. At any time, Hauser may
         require ZGNA to resell to Hauser all or any portion of the inventory
         purchased by ZGNA at the same price at which ZGNA purchased the
         inventory and require ZGNA to purchase substantially similar raw
         material and finished product having a value substantially equivalent
         to the repurchased inventory. Hauser will recognize revenue from the
         transaction upon the sale of the inventory to an unrelated party.

(1)      Reflects the removal of revenues and expenses related to the paclitaxel
         business. As a result of the Merger, Hauser will exit the business of
         producing bulk paclitaxel. All approvals necessary to exit the
         paclitaxel business have been obtained. 
    
   
(2)      Reflects the estimated amortization of goodwill using a twenty year
         life that would have occurred during the pro forma period. Goodwill
         amortization expense would have been approximately $1,673,485 during
         the year ended April 30, 1998. Goodwill is dependent upon the number of
         shares ultimately issued and the fair value of the assets and
         liabilities of the contributed subsidiaries, which could differ from
         the amounts assumed for purposes of the unaudited pro forma statements.
         If all escrow shares are returned to Hauser and canceled, pro forma
         goodwill amortization expense would be approximately $1,133,000. See
         "The Escrow Agreement".
    
   
(3)      No adjustment has been made to interest expense to account for changes
         in the amount of interest and commitment fees that would be paid
         relating to the new credit facility obtained by Hauser as part of the
         Merger because any estimate of utilization of credit facilities is not
         factually supportable.
    
   
(4)      Reflects estimated pro forma income tax at the combined statutory rate
         of approximately 40% and includes the effect of goodwill amortization,
         which is non-deductible for tax purposes.

                    HAUSER, INC. AND CONTRIBUTED SUBSIDIARIES
           NOTES TO UNAUDITED PRO FORMA CONDENSED COMBINED STATEMENTS
            OF OPERATIONS FOR THE NINE MONTHS ENDED JANUARY 31, 1999

    
   
(1)      Reflects the removal of revenues and expenses related to the paclitaxel
         business. As a result of the Merger, Hauser will exit the business of
         producing bulk paclitaxel. All approvals necessary to exit the
         paclitaxel business have been obtained.
    
   
(2)      Reflects the estimated additional revenue to be realized from the sale
         of product from Wilcox (a Contributed Subsidiary) to ZBI during the
         nine months ended January 31, 1999. During this period, Wilcox sold
         product to ZBI at cost. The parties have agreed that Wilcox will charge
         ZBI prices no less favorable than those charged to unrelated third
         parties.
    
   
(3)      Reflects the estimated amortization of goodwill using a twenty year
         life that would have occurred during the pro forma period. Goodwilll
         amortization expense would have been approximately $1,255,000 during
         the nine months ended January 31, 1999. Goodwill is dependent upon the
         number of shares ultimately issued and the fair value of the assets and
         liabilities of the contributed subsidiaries which could differ from the
         amounts assumed for purposes of the unaudited pro forma statements. If
         all escrow shares are returned to Hauser and canceled, pro forma
         goodwill amortization expense would be approximately $850,000. See 
         "THE MERGER AGREEMENT - The Escrow Agreement".
    
   
(4)      No adjustment has been made to interest expense to account for changes
         in the amount of interest and commitment fees that would be paid
         relating to the new credit facility obtained by Hauser as part of the
         Merger because any estimate of utilization of credit facilities is not
         factually supportable.
    
   
(5)      Reflects estimated pro forma income tax which includes the effect of
         goodwill amortization, which will be non-deductible for tax purposes.

                  ARRANGEMENTS AFFECTING CONTROL OF THE COMPANY

   

         As of March 31, 1999, the Officers and Directors of Hauser beneficially
owned 904,320 shares of Common Stock or approximately 8.3% of the total shares
issued and outstanding (assuming exercise of all warrants and options deemed to
be beneficially owned by these persons). After the Merger, and assuming the
acceleration of certain options, officers and directors of Hauser will own
705,327 shares of 3.4% of the total shares issued and outstanding (assuming
exercise of all warrants and options deemed to be beneficially owned by these
persons).

    

POSSIBLE APPLICATION OF CALIFORNIA CORPORATIONS CODE

         Pursuant to Section 2115 of the California Corporations Code, a foreign
parent corporation (even though it does not itself transact intrastate business)
is subject to certain provisions of the California Corporations Code if both (1)
more than 50% of the outstanding Common Stock is held by persons having
addresses in California and (2) if the average of the property, payroll and
sales tax factors under California law is more than 50% during its latest full
income year. If applicable, Hauser shareholders would have certain rights under
California law that may be different than under the Articles of Incorporation of
Hauser and under Colorado law relating to the election and removal of directors,
filling of director vacancies, directors' standard of care, liability of
directors for unlawful distributions, indemnification of directors and officers,
liability of shareholders who receive unlawful distributions, annual
shareholders meetings, cumulative voting, supermajority voting requirement,
limitations on sale of assets, limitations on mergers, reorganizations,
dissenters' rights, records and reports and rights of inspection. ZGNA and ZBI
currently have addresses in California, but based upon the proforma financial
information, Hauser does not believe the average property, payroll or sales tax
factors will exceed 50%. However, there is no assurance that in the future such
average will not exceed 50%, particularly if the Powders Option is exercised.

   
                         APPROVAL OF REVERSE STOCK SPLIT
    
   

         The Board of Directors has approved, and recommends that the 
shareholders approve, a resolution to effect a reverse split (the "REVERSE 
STOCK SPLIT") of the outstanding shares of Common Stock, whereby Hauser would 
issue one (1) new share of Common Stock in exchange for between two (2) and 
five (5) shares of presently outstanding Common Stock (the "RESOLUTION"). The 
Board believes that shareholder approval of an exchange ratio range (as 
opposed to approval of a specified exchange ratio) in which the Reverse Stock 
Split may be effected will provide the Board with maximum flexibility to 
achieve the purposes of the Reverse Stock Split and is in the best interests 
of Hauser and its shareholders. This Resolution will be effective if 1) the 
Merger is approved and 2) the Reverse Stock Split is necessary to meet the 
NASDAQ minimum bid price on the Closing Date of the Merger. See "APPROVAL OF 
REVERSE STOCK SPLIT - Reasons For and the Effect of the Proposed Reverse 
Stock Split".

    
   

         The Board of Directors will determine the effective date of the 
Reverse Stock Split, if any.

    
   
REASONS FOR AND THE EFFECT OF THE PROPOSED REVERSE STOCK SPLIT
    
   

         In March 1999, Hauser was advised by NASDAQ that the proposed Merger
was deemed a "change of control" by NASDAQ that would require Hauser to submit a
new Application for Initial Listing as a NASDAQ National Market company. One of
the requirements for initial listing as a NASDAQ National Market company is that
the trading price of the stock be at least $5.00 per share.

    
   

         Based on the closing price for the Common Stock on March 31, 1999 
($2.75), Hauser does not satisfy the minimum bid price for the Common Stock 
of $5.00 per share. The primary purpose of the Reverse Stock Split is to 
increase the market value per share of the Common Stock in order to meet the 
National Market's minimum bid price. The reduction in the number of shares of 
Common Stock outstanding caused by the Reverse Stock Split is intended to 
increase the per share market price of the Common Stock, thereby allowing the 
Common Stock to qualify for continued listing on the National Market. If the 
shareholders approve this proposal, the Board of Directors may authorize the 
Reverse Stock Split if necessary to meet the minimum bid price. The Board of 
Directors will select a level within the exchange ratio range for the Reverse 
Stock Split which the Board believes will allow the Common Stock to qualify 
for listing on the National Market. The Reverse Stock Split will affect all 
shareholders equally and each shareholder's percentage equity interest in 
Hauser will remain unchanged.

    

                                       53
<PAGE>

   

         THE BOARD OF DIRECTORS STRONGLY URGES SHAREHOLDERS TO VOTE FOR THE
REVERSE STOCK SPLIT. IF SHAREHOLDERS FAIL TO APPROVE THE REVERSE STOCK SPLIT,
THE COMMON STOCK WILL LIKELY BE DELISTED FROM THE NASDAQ NATIONAL MARKET. IT IS
A CONDITION TO THE OBLIGATION OF ZGNA AND ZBI TO CONSUMMATE THE MERGER THAT
HAUSER COMMON STOCK BE LISTED ON THE NASDAQ NATIONAL MARKET, OR ON SOME OTHER
STOCK EXCHANGE.

    
   

         In the event this Resolution is not adopted by Hauser's shareholders,
and the Common Stock minimum bid price does not exceed $5.00 on or before the
Closing Date of the Merger, Hauser has been advised that the Common Stock will
be delisted by NASDAQ. No assurance can be given that the Common Stock will meet
the requirements for listing on any other established trading market, including
the Nasdaq Small Cap Market, in the event the Resolution is not approved by
Hauser's shareholders. In addition, the listing of the Common Stock on the
National Market is conditioned on Hauser being able to satisfy all of the
National Market's qualitative and quantitative requirements for initial listing.
There can be no assurance that Hauser will be able to satisfy all of these
requirements or continue to satisfy these requirements in the future.

    
   

         The Reverse Stock Split also may enhance the acceptability of the 
Common Stock by the financial community and investing public. Theoretically, 
the bid price of the shares should not, by itself, affect Hauser's reputation 
in the financial community, but in practice this is not necessarily the case, 
as many investors look upon a stock trading below $5.00 as unduly speculative 
in nature and, as a matter of policy or practice, avoid investments in such 
stocks. Hauser also believes the current per share price of the Common Stock 
has reduced the effective marketability of the shares because of the 
reluctance of many leading brokerage firms to recommend low-priced securities 
to their clients. Further, various brokerage house policies and practices 
tend to discourage individual brokers within firms from dealing in low-priced 
stocks. Some of those policies and procedures pertain to the payment of 
brokers' commissions and to time-consuming procedures that make the handling 
of low-priced stocks economically unattractive to brokers. In addition, the 
structure of trading commissions tends to have an adverse impact upon holders 
of low-priced stocks because the brokerage commission on a sale of a 
low-price stock generally represents a higher percentage of the sales price 
than the commission on higher priced issues. Hauser also believes that many 
or more brokers and other "margin loan" makers are unwilling to lend against 
stock trading below $5.00 per share. Hauser believes that all of the 
foregoing factors tend to depress the market for the Common Stock.

    
   

         Although there can be no assurance that the price of the Common Stock
after the Reverse Stock Split will actually increase in an amount proportionate
to the decrease in the number of outstanding shares, the proposed Reverse Stock
Split is intended to result in a price level for the Common Stock that will
mitigate or eliminate the foregoing factors that impact the market for the
Common Stock. There is also no assurance that the market for the Common Stock
will be improved Hauser cannot predict what actual effect the Reverse Stock
Split will have on the market price of the Common Stock.

    
   

         Based on the 20,525,000 shares of Common Stock that are presumed to be
outstanding on the Closing Date of the Merger, the following table reflects the
percentage reduction in the outstanding shares of Common Stock and the number of
shares of Common Stock that would be outstanding as a result of the Reverse
Stock Split:

    
   
<TABLE>
<CAPTION>
     PROPOSED REVERSE STOCK SPLIT        PERCENTAGE REDUCTION          SHARES TO BE OUTSTANDING

     <S>                                 <C>                           <C>
                1 for 2                           50%                         10,262,500
                1 for 3                           66%                          6,841,666
                1 for 4                           75%                          5,131,250
                1 for 5                           80%                          4,105,000
</TABLE>
    
   

         The Reverse Stock Split would not affect the proportionate equity
interest in Hauser of any holder of Common Stock, except as may result from the
provisions for the treatment of fractional shares as described below. Following
the Reverse Stock Split, each share of Common Stock will entitle the holder
thereof to one vote per share and will otherwise be identical to the Common
Stock prior to such event.

    

                                       54
<PAGE>

   
EFFECT ON OUTSTANDING OPTIONS AND WARRANTS
    
   

         As of March 31, 1999, there were outstanding options to purchase an 
aggregate of 962,974 shares of Common Stock pursuant to Hauser employee stock 
option plans and warrants to purchase an aggregate of 48,477 shares of Common 
Stock. All of the outstanding options and warrants are subject to provisions 
for adjustments in the number of shares covered thereby, and the exercise 
price thereof, in the event of a reverse stock split. If the proposed Reverse 
Stock Split is approved and effected, there will be a proportionate reduction 
in the number of shares of Common Stock subject to outstanding options and 
warrants, depending on the ratio selected by the Board of Directors, and the 
exercise price per share would be proportionately increased. The number of 
shares authorized and available for grant under the 1987 Non-Statutory Stock 
Option Plan and the 1992 Incentive Stock Option Plan will be proportionately 
reduced. The number of shares authorized for issuance under the 1999 Stock 
Incentive Plan will be unaffected.

    
   
EXECUTION AND CONSEQUENCES OF A REVERSE STOCK SPLIT
    
   

         Each stock certificate representing issued and outstanding shares of 
Common Stock prior to the effective date of the Reverse Stock Split will, 
after such effective date, represent the appropriate number of shares of 
Common Stock reflecting the Reverse Stock Split. It will not be necessary for 
shareholders to exchange their existing stock certificates. Shareholders may, 
however, exchange their certificates if they so choose.

    
   

         No scrip or fractional certificates will be issued in the Reverse 
Stock Split, and no such fractional share interest would entitle the holder 
thereof to vote or to any rights of a shareholder of the Company. In lieu of 
any such fractional shares, and solely for the purpose of avoiding the 
expense and inconvenience of issuing fractional shares, Hauser's transfer 
agent, American Securities Transfer & Trust, Inc. (the "TRANSFER AGENT") will 
round up to the next higher whole share any fractional shares that result 
from the Reverse Stock Split.

    
   

         The Reverse Stock Split may leave certain shareholders with "odd 
lots" of the Common Stock, i.e., stock in amounts of less than 100 shares. 
These shares may be more difficult to sell, or require a greater commission 
per share to sell, than shares in even multiples of 100.

    
   
CERTAIN FEDERAL INCOME TAX CONSEQUENCES
    
   

         The following description of federal income tax consequences of the 
Reverse Stock Split is based on the Internal Revenue Code, the applicable 
Treasury Regulations promulgated thereunder, judicial authority and current 
administrative rulings and practices as in effect on the date of this Proxy 
Statement. This discussion is for general information only and does not 
address all the tax consequences that may be relevant to a particular 
shareholder (such as non-resident aliens, broker-dealers or insurance 
companies). Furthermore, no foreign, state or local tax consequences are 
discussed herein. Accordingly, shareholders are urged to consult their own 
tax advisors to determine the specific tax consequences of the Reverse Stock 
Split to them.

    
   
         The exchange of shares of stock for shares of post-split stock will 
not result in recognition of gain or loss. The holding period of the shares 
of post-split stock will include the shareholder's holding period for the 
shares of stock exchanged therefor, and the aggregate tax basis of the shares 
of the post-split stock will be the same as the aggregate tax basis of the 
shares of stock exchanged therefor.

    
   
PROPOSED RESOLUTION
    
   

         The proposed resolution is as follows:
    
   

         The Board of Directors shall have the authority to split the 
outstanding shares of Common Stock by a range of two to one to five to one 
(the "Reverse Stock Split"); provided, however, that (1) no fractional share 
shall be issued pursuant to the Reverse Stock Split and (2) no such 
fractional share interest will entitle the holder thereof to vote, or to any 
rights of a shareholder of Hauser. In lieu of any such fractional shares, 
Hauser's transfer agent American Securities Transfer & Trust, Inc., will 
round up to the next higher whole share any fractional shares that result 
from the Reverse Stock Split. The Reverse Stock Split will be effective if 1) 
the Merger is approved and 2) it is necessary to meet the NASDAQ minimum bid 
price on the Closing Date of the Merger.

    

                                       55
<PAGE>

   
APPRAISAL RIGHTS
    
   

         Holders of Common Stock have no appraisal rights under Colorado law 
in connection with the Reverse Stock Split because the shares of Common Stock 
are listed on the Nasdaq National Market System on the Record Date for the 
meeting.

    
   
VOTE REQUIRED AND RESERVATION OF RIGHTS
    
   

         Approval of the Reverse Stock Split and adoption of the Resolution 
requires the affirmative vote of a majority of the quorum present in person 
or by proxy at the Special Meeting. Broker non-votes will not be counted. The 
Board of Directors reserves the right, notwithstanding shareholder approval 
and without further action by the shareholders, to elect not to proceed with 
the Reverse Stock Split, if at any time prior to the Closing Date of the 
Merger, the Board of Directors, in its sole discretion, determines that the 
Reverse Stock Split is no longer in the best interest of the Company and its 
shareholders.

    
   
BOARD RECOMMENDATIONS
    
   

         The Board of Directors recommends that shareholders vote "FOR" 
approval of the Reverse Stock Split. IF SHAREHOLDERS FAIL TO APPROVE THE 
REVERSE STOCK SPLIT, THE COMMON STOCK WILL LIKELY BE DELISTED FROM THE NASDAQ 
NATIONAL MARKET AND IF THE COMMON STOCK IS NOT LISTED ON ANOTHER STOCK 
EXCHANGE, ZGNA AND ZBI WILL HAVE NO OBLIGATION TO CONSUMMATE THE MERGER.

                    APPROVAL OF THE 1999 STOCK INCENTIVE PLAN

   

         On January 28, 1999, the Board adopted, subject to shareholder 
approval, the Hauser, Inc. 1999 Stock Incentive Plan under which 700,000 
shares of Common Stock were reserved for issuance pursuant to stock and 
option awards. If the Reverse Stock Split occurs, the number of shares of 
Common Stock under the 1999 Stock Incentive Plan will not be reduced.

    

         The Board believes that the 1999 Stock Incentive Plan is in the best 
interests of Hauser and its shareholders so that Hauser may offer to current 
and prospective key employees, consultants and directors an opportunity to 
participate in the equity of Hauser. The purpose of the 1999 Stock Incentive 
Plan is to promote the interests of Hauser and its shareholders by helping 
Hauser and its subsidiaries attract, retain and motivate individuals who are 
essential to the success of Hauser and its subsidiaries. Upon the closing of 
the Merger, Hauser will be a significantly larger company with additional key 
personnel. In order to provide incentives to these individuals and closely 
align their interests with those of the shareholders, the Board believes that 
an equity incentive plan such as the 1999 Stock Incentive Plan is necessary 
and in the best interests of Hauser and its shareholders.

         Hauser is seeking shareholder approval of the 1999 Stock Incentive 
Plan in order to comply with the requirements of Sections 162(m) and 422 of 
the Code and the requirements of the NASDAQ National Market System ("NASDAQ").

    THE BOARD UNANIMOUSLY RECOMMENDS A VOTE FOR THE 1999 STOCK INCENTIVE PLAN

         The 1999 Stock Incentive Plan will be approved upon the affirmative 
vote of the holders of a majority of the quorum at the Special Meeting. 
Unless otherwise specified, proxies solicited by the Board will be voted FOR 
the adoption of the 1999 Stock Incentive Plan. The approval of the Merger is 
not conditioned upon approval of the 1999 Stock Incentive Plan, but the 
approval of the 1999 Stock Incentive Plan is conditioned upon approval of the 
Merger. The following summary of the 1999 Stock Incentive Plan is qualified 
in its entirety by express reference to the text of the 1999 Stock Incentive 
Plan, a copy of which is attached to this Proxy Statement as Appendix I.

EFFECTIVE DATE; DURATION

         The 1999 Stock Incentive Plan will become effective upon approval by 
the shareholders of Hauser. The expiration date of the 1999 Stock Incentive 
Plan, after which no further awards may be granted, is February 1, 2009.

ELIGIBILITY; AWARDS

         Key employees, directors and consultants of Hauser and its 
subsidiaries are eligible to receive discretionary stock-based awards under 
the 1999 Stock Incentive Plan. Options to purchase Common Stock ("OPTIONS") 
may be granted to all eligible individuals. Options granted to eligible 
employees may be qualified as "incentive stock options" within the meaning of 
Section 422 of the Code ("ISOS") or may be Options which are not so qualified 
("NQSOS"). In addition, shares of Common Stock may be granted to members of 
the Board, who are not employees of Hauser or any subsidiary in lieu of cash 
compensation. As of January 15, 1999, the approximate number of employees 
eligible to participate in the 1999 Stock Incentive Plan was 325. 
Approximately 65 additional employees of the Contributed Subsidiaries will be 
eligible under the 1999 Stock Incentive Plan if the Merger is approved and 
closes. There are currently 5 outside directors on the Board and, following 
the Merger, Hauser expects that there will be 6 outside directors eligible 
under the 1999 Stock Incentive Plan. The benefits received by or allocated to 
eligible persons under the 1999 Stock Incentive Plan are not determinable.

ADMINISTRATION

         The 1999 Stock Incentive Plan will be administered by the Board or a 
committee of at least two individuals appointed by the Board (the 
"COMMITTEE"). The Committee, in its sole discretion, has full authority to 
determine which individuals may participate in the 1999 Stock Incentive Plan 
and the type, extent and terms of the stock-based awards to be granted. The 
Committee may reprice and accelerate vesting schedules with respect to 
outstanding Options. In addition, the Committee will interpret the 1999 Stock 
Incentive Plan and make all other determinations with respect to the 
administration of the 1999 Stock Incentive Plan.

TERMS AND CONDITIONS OF AWARDS

         The terms and conditions of Options will be set forth from time to 
time in agreements between Hauser and the individuals receiving such awards. 
Such terms include vesting conditions and the expiration dates for the 
Options, which may not exceed ten years from the date of grant. Options may 
expire earlier than the expiration date set forth in the Option agreement 
upon an optionee's termination of employment, as determined by the Committee. 
The exercise price per share of an Option is determined by the Committee at 
the time of grant, but must be at least the Fair Market Value (as defined in 
the 1999 Stock Incentive Plan) of a share of Common Stock on the date of 
grant. Unless otherwise determined by the Committee, either at the time of 
grant or prior to exercise, Options are not transferable otherwise than by 
will or the laws of descent and distribution. ISOs may not be granted to an 
individual who, at the date of grant, owns directly or indirectly stock 
possessing more than 10 percent of the total combined voting power of all 
classes of stock of Hauser or of any parent or subsidiary of Hauser, unless 
the ISO (i) has an exercise price of at least 110 percent of the Fair Market 
Value of the Common Stock on the date of grant of the Option, and (ii) cannot 
be exercised more than 5 years after the date of grant. To the extent that 
the aggregate Fair Market Value per share with respect to which ISOs become 
exercisable for the first time in any calendar year exceeds $100,000, such 
Options will be NQSOs. The Option exercise price may be paid by cash or 
certified check, or at the Committee's discretion, (i) with shares of Common 
Stock held by the optionee for at least six months, (ii) by having Hauser 
withhold shares of Common Stock being purchased, (iii) with other property 
having a value equal to the aggregate exercise price, (iv) through a brokered 
exercise, or (v) by delivery of a promissory note to Hauser.

         The Committee may, in its sole discretion, make grants of Common 
Stock to members of the Board who are not also employees of Hauser or a 
subsidiary in lieu of cash compensation for their services as members of the 
Board. The Committee may impose such terms and conditions as it deems 
appropriate for stock grants to directors.

ADJUSTMENTS FOR RECAPITALIZATION, MERGER, ETC. OF HAUSER

         In the event of any change in the outstanding shares of Common Stock 
or capital structure of Hauser resulting from any recapitalization, merger, 
consolidation, spin-off, combination or exchange of shares or other similar 
corporate change or a change in the law or any other event which interferes 
with the intended operation of the 1999 Stock Incentive Plan, the Committee 
will make such substitution or adjustment, if any, as it deems equitable, as 
to (i) the number or kind of shares of Common Stock or other securities 
reserved for issuance pursuant to the 1999 Stock Incentive Plan, (ii) the 
number or kind of shares of Common Stock or other securities covered by 
outstanding Options, and (iii) the Option price thereof.

         In the event (i) Hauser is merged with another corporation or entity 
and, in connection therewith, consideration is received by shareholders of 
Hauser in a form other than stock or other equity interests of the surviving 
entity, (ii) all or substantially all of the assets of Hauser are acquired by 
another person, or (iii) Hauser is reorganized or liquidated, then the 
Committee may, in its sole discretion, with notice, cash-out and cancel any 
particular or all outstanding Options.

CHANGE IN CONTROL

         In the event of a Change in Control (as defined in the 1999 Stock 
Incentive Plan), all then unexercised and unexpired outstanding Options, 
which would otherwise become vested within twelve months after such Change in 
Control, shall become immediately vested and exercisable.

                                       58
<PAGE>

SHARES SUBJECT TO THE INCENTIVE PLAN
   
         As noted above, the total number of shares of Common Stock reserved 
for issuance under the 1999 Stock Incentive Plan is 700,000. No more than 
250,000 shares of Common Stock may be issued to any one person pursuant to 
awards of Options during any one year.
    

MARKET VALUE

   

         The market value of the Common Stock on NASDAQ on April 5, 1999 was 
$2.625 per share.

    

AMENDMENT AND TERMINATION

         The Board may at any time terminate the 1999 Stock Incentive Plan. 
With the consent of optionees, the Board or the Committee may cancel, reduce 
or otherwise alter outstanding Options. The Board or the Committee may, at 
any time or from time to time, amend or suspend and, if suspended, reinstate, 
the 1999 Stock Incentive Plan in whole or in part; provided, however that no 
amendment which requires shareholder approval in order for Options granted 
pursuant to the 1999 Stock Incentive Plan to be exempt from the application 
of Section 162(m) of the Code or for ISOs to continue to meet the 
requirements of Section 422 of the Code, shall be effective unless the same 
is approved by the requisite vote of the shareholders of Hauser. Any options 
outstanding after any such termination of the 1999 Stock Incentive Plan shall 
remain in effect in accordance with their terms.

FEDERAL TAX CONSEQUENCES

         The following is a brief discussion of the Federal income tax 
consequences of Option transactions under the 1999 Stock Incentive Plan based 
on the Code, as in effect as of the date of this Proxy Statement. This 
discussion is not intended to be exhaustive and does not describe any state 
or local tax consequences. Recipients of Common Stock or Options should 
consult with their own tax advisors to determine the specific tax 
consequences to them.

         ISOs. No taxable income is realized by the optionee upon the grant 
or exercise of an ISO. If Common Stock is issued to an optionee pursuant to 
the exercise of an ISO, and if no disqualifying disposition of such shares is 
made by such optionee within two years after the date of grant or within one 
year after the transfer of such shares to such optionee, then (1) upon the 
sale of such shares, any amount realized in excess of the Option price will 
be taxed to such optionee as a long-term capital gain and any loss sustained 
will be a long-term capital loss, and (2) no deduction will be allowed to 
Hauser for Federal income tax purposes.

         If the Common Stock acquired upon the exercise of an ISO is disposed 
of prior to the expiration of either holding period described above, 
generally, (1) the optionee will realize ordinary income in the year of 
disposition in an amount equal to the excess (if any) of the Fair Market 
Value of such shares at exercise (or, if less, the amount realized on the 
disposition of such shares) over the Option price paid for such shares and 
(2) Hauser will be entitled to deduct such amount for Federal income tax 
purposes if the amount represents an ordinary and necessary business expense. 
Any further gain (or loss) realized by the optionee upon the sale of the 
Common Stock will be taxed as short-term or long-term capital gain (or loss), 
depending on how long the shares have been held, and will not result in any 
deduction by Hauser.

         If an ISO is exercised more than three months following termination 
of employment (subject to certain exceptions for disability or death), the 
exercise of the Option will generally be taxed as the exercise of a NQSO, as 
described below.

         For purposes of determining whether an optionee is subject to an 
alternative minimum tax liability, an optionee who exercises an ISO generally 
would be required to increase his or her alternative minimum taxable income, 
and compute the tax basis in the stock so acquired, in the same manner as if 
the optionee had exercised a NQSO. Each optionee is potentially subject to 
the alternative minimum tax. In substance, a taxpayer is required to pay the 
higher of his/her alternative minimum tax liability or his/her "regular" 
income tax liability. As a result, a taxpayer has to determine his/her 
potential liability under the alternative minimum tax.

                                      59
<PAGE>

         NQSOs. With respect to NQSOs: (1) no income is realized by the 
optionee at the time the Option is granted; (2) generally, at exercise, 
ordinary income is realized by the optionee in an amount equal to the excess, 
if any, of the Fair Market Value of the shares on such date over the exercise 
price, and Hauser is generally entitled to a tax deduction in the same 
amount, subject to applicable tax withholding requirements; and (3) at sale, 
appreciation (or depreciation) after the date of exercise is treated as 
either short-term or long-term capital gain (or loss) depending on how long 
the shares have been held.

SPECIAL RULES APPLICABLE TO CORPORATE INSIDERS

         As a result of the rules under Section 16(b) of the Exchange Act 
("SECTION 16(b)"), and depending upon the particular exemption from the 
provisions of Section 16(b) utilized, officers and directors of Hauser and 
persons owning more than 10 percent of the outstanding shares of stock of 
Hauser ("INSIDERS") may not receive the same tax treatment as set forth above 
with respect to the grant and/or exercise of Options. Generally, Insiders 
will not be subject to taxation until the expiration of any period during 
which they are subject to the liability provisions of Section 16(b) with 
respect to any particular Option. Insiders should check with their own tax 
advisers to ascertain the appropriate tax treatment for any particular Option.

NEW PLAN BENEFITS

         The grant of Options and Common Stock under the 1999 Stock Incentive 
Plan is entirely within the discretion of the Committee. Hauser cannot 
forecast the extent of Option and Common Stock grants that will be made in 
the future. Therefore, Hauser has omitted the tabular disclosure of the 
benefits or amounts allocated under the 1999 Stock Incentive Plan. 
Information with respect to compensation paid and other benefits, including 
Options and Common Stock, granted in the 1998 fiscal year to the Named 
Executive Officers is set forth in the Summary Compensation Table below.

                       DIRECTOR AND EXECUTIVE COMPENSATION

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

         Directors Coleman, Cristol, Saydah and Tolbert comprise Hauser's 
Compensation Committee. All are non-employee directors and none have ever 
been officers of Hauser.

DIRECTOR COMPENSATION

         During fiscal 1998, Hauser's non-employee directors were granted 
options to purchase a total of 17,250 shares of Common Stock for services 
rendered to Hauser at an average price of $6.54 per share (100% of fair 
market value on the date of grant). Directors receive an option to purchase 
300 shares for Board service and options to purchase 150 shares for 
attendance at each meeting of the Board or each committee thereof. The 
options are exercisable for a five-year period.

         In May 1992, the Board approved a two-step plan to compensate 
outside directors. The plan includes options for Board and committee service 
as discussed above, and an annual cash payment of $10,000 per outside 
director plus an annual payment of $2,500 for a committee chairman. During 
fiscal 1998, Hauser's five outside directors received cash compensation of 
approximately $45,375 in the aggregate pursuant to this plan, excluding 
reimbursement of travel expenses. If the Merger closes, this cash and option 
compensation plan for outside directors will terminate and outside directors 
will be compensated through the Incentive Plan. See "APPROVAL OF THE 1999 
STOCK INCENTIVE PLAN".

         During the fiscal year ended April 30, 1998, Hauser's Board held 
nine meetings. The Compensation Committee, consisting of directors Coleman, 
Cristol, Saydah and Tolbert, held seven meetings during the fiscal year. The 
primary function of the Compensation Committee is to recommend raises and 
bonuses, if any, for Hauser's officers and to grant stock option awards to 
Hauser's employees. The Audit Committee consisting of directors Haddon and 
Saydah held five meetings during the fiscal year. The function of the Audit 
Committee is to oversee management's internal controls, review periodic 
filings with the Securities and Exchange Commission, and review any

                                      60
<PAGE>

transactions between Hauser and its officers, directors or affiliated 
entities. The Nominating Committee consisting of directors Saydah and Coleman 
held three meetings during the fiscal year. The function of the Nominating 
Committee is to investigate succession planning for Hauser's executives and 
review nominations to the Board. The Nominating Committee will consider 
shareholder recommendations for nominations to the Board if presented in 
writing by July 31, 1999.

COMPLIANCE WITH SECTION 16(a)

         Section 16(a) of the Securities Exchange Act of 1934, as amended, 
requires Hauser's directors, executive officers and holders of more than 10% 
of the Common Stock to file with the Securities and Exchange Commission 
initial reports of ownership and reports of changes in ownership of the 
Common Stock. Based solely upon a review of Forms 3, 4 and 5 and amendments 
thereto furnished to Hauser with respect to the fiscal year ended April 30, 
1998, to the best of Hauser's knowledge, Hauser's directors, officers and 
holders of more than 10% of its Common Stock complied with all Section 16(a) 
filing requirements.

COMPENSATION COMMITTEE REPORT OF COMPENSATION OF EXECUTIVE OFFICERS OF HAUSER

         The Compensation Committee of the Board and the Company's Chief 
Executive Officer have furnished the following joint report on executive 
compensation. The specific responsibility of the Chief Executive Officer to 
furnish information to the Compensation Committee has been outlined below. 
During fiscal 1998, the Compensation Committee set the salaries and bonus 
compensation for the Chief Executive Officer, two Vice Presidents, the Chief 
Financial Officer and the Corporate Secretary. The salaries and bonus plans 
for the three Named Executives, Messrs. Katz, Damon and Gordon, are set by 
contracts which the Company assumed as a result of the acquisition of Shuster 
Laboratories, Inc., in July 1995. These contracts expired in July 1998. See 
"Certain Transactions.

         EXECUTIVE OFFICER COMPENSATION

         The Committee has responsibility for making recommendations for 
compensation and compensation policy. The Committee's first objective is to 
provide a strong and direct link among shareholder value, Company performance 
and executive compensation. The second objective is to promote long-term 
stable growth and development. The Committee believes that the Company's 
corporate development is dependent on its ability to attract and retain high 
quality people. The Chief Executive Officer's responsibility is to evaluate 
for the Compensation Committee the individual performance of the executive 
officers, other than himself. He is also asked to report on the performance 
reviews of these officers to the Compensation Committee and make suggestions 
of the percentage of discretionary cash and discretionary stock bonuses to be 
awarded.

         The Company's compensation program consists of three key elements: 
base salary, short term discretionary bonuses and profit sharing, plus long 
term discretionary incentive stock option awards. Compensation for Hauser's 
executive officers involves a high proportion of pay which is at risk, a 
variable bonus based on individual performance, and stock options, which 
directly relate a portion of the officer's compensation to the long-term 
stock price appreciation realized by the Company's shareholders. The 
executive officers also participate in a 401(k) retirement plan and a medical 
insurance plan with other employees.

         BASE SALARY. The Compensation Committee's policy is to provide 
compensation competitive within the Denver/Boulder metropolitan area while 
giving consideration to national compensation. The Committee also considers 
the salary recommendations and performance reviews submitted by the Chief 
Executive Officer.

         In evaluating the performance of the executive officers other than 
himself, the Chief Executive Officer measures individual leadership skills, 
business development skills, management skills, external relations and 
communication skills. The executive officers' individual contribution to 
corporate financial results for the fiscal year, including revenue growth and 
changes in net income and earnings per share, were also evaluated. In 
addition, extraordinary management and supervisory responsibilities were 
taken into consideration. The Compensation Committee made no changes to the 
base salary of the named executive officers during fiscal year 1998.

         DISCRETIONARY CASH BONUSES PAID IN FISCAL YEAR 1998. During fiscal 
year 1997, the Compensation Committee developed a series of specific goal 
oriented compensation awards for fiscal year 1998. Fiscal year 1998

                                      61
<PAGE>

awards for these executives were based on achieving operating income goals 
which were not met. After reviewing the Company's annual report and audited 
financial statements for the fiscal year ended April 30, 1998, the 
Compensation Committee awarded no cash bonuses for fiscal year 1998. Mr. Wehr 
received a $20,000 cash bonus during fiscal year 1998 as part of his original 
employment agreement.

         The Compensation Committee awarded phantom stock bonuses to Messrs. 
Katz, Gordon and Damon, employees of the Company's wholly-owned subsidiary, 
Shuster Laboratories. The bonuses represent phantom stock payments made to 
Messrs. Katz, Damon and Gordon for their phantom stock in Shuster, Inc. The 
Shuster Phantom Stock Plan was a bonus plan through which the individuals 
earned an equity interest in Shuster, Inc. The payments were made monthly and 
terminated in July 1998.

         The Compensation Committee instructs the Chief Executive Officer to 
complete performance evaluations for each of the executive officers other 
than himself. The Chief Executive Officer's evaluation is an informal report 
to the Compensation Committee along with informal suggestions of the 
percentage stock and cash bonuses to be awarded. In evaluating the 
performance, the Chief Executive Officer measures the leadership, strategic 
planning, financial results, business development, management skills, 
external relations and communication skills. The Compensation Committee does 
not adopt the suggestions of the Chief Executive Officer but rather adjusts 
those suggestions to fit the parameters of their overall knowledge and 
experience with the executive officers. The Compensation Committee evaluates 
these performance reviews. Factors, other than the report of the Chief 
Executive Officer, reviewed by the Compensation Committee include increased 
management or supervisory responsibilities and the direct impact of the 
departments supervised by those executive officers on the net sales, 
operating income and earnings per share of the Company.

         STOCK OPTIONS. It is the Compensation Committee's policy that a 
significant portion of the total compensation package for its executive 
officers will be derived from stock options. The Board of Directors adopted 
the NonQualified Stock Option Plan approved by shareholders in 1987 and the 
1992 Incentive Stock Option Plan approved by shareholders in 1992.

         During any fiscal year, the named executive officers of the Company 
may receive incentive stock options or non-qualified stock options based on 
performance. Discretionary stock options distributed to the named executive 
officers were determined by the Compensation Committee and were based upon 
the same performance review criteria previously stated. The number of options 
granted were based upon the individual executive's performance during the 
fiscal year, anticipated future contributions based on that performance, and 
the officer's ability to impact corporate financial results. Additional 
factors considered by the Committee included increased management or 
supervisory responsibilities and the direct impact of the departments 
supervised by those executive officers on the net sales, operating income and 
earnings per share of the Company. During fiscal 1998, executive officers 
received stock options to purchase 141,800 shares at an average price of 
$5.90.

         Discretionary stock option awards granted to the Named Executive 
Officers during fiscal year 1998, for fiscal year 1997 performance, were 
determined based upon the Chief Executive Officer's evaluation report to the 
Committee of individual performances plus the Compensation Committee's own 
knowledge and experience with these same senior executive officers. The 
Compensation Committee observes that the executive officers continue to own a 
relatively low percentage of total outstanding stock and deems it beneficial 
to shareholders as a whole to increase the equity ownership of the executive 
officers.

         The Compensation Committee regularly reviews other possible forms of 
incentive compensation and modifies or supplements the existing programs when 
appropriate. The stock awards continue the Committee's policy that Hauser's 
executive officers should have a strong motivation to improve the performance 
of Hauser and enhance Hauser's stock value. At present and in future years, 
successful development of current and diversified projects and further growth 
will be important considerations in discretionary bonuses, both cash and 
stock.

         CHIEF EXECUTIVE OFFICER COMPENSATION

         As Chief Executive Officer, Dr. Stull is compensated based on a 
review of his performance by the Compensation Committee. The key factor 
measured by the Compensation Committee in determining Dr. Stull's 
compensation package was its assessment of his ability and dedication to 
enhancing the long-term value of the

                                      62
<PAGE>

Company by continuing to provide the leadership and vision that he has 
provided throughout his tenure as Chief Executive Officer. The base salary 
paid to the Chief Executive Officer is based upon an assessment of the nature 
of the position, the leadership exercised by, and the contribution, 
experience and Company tenure of Dr. Stull. During fiscal 1998, Dr. Stull's 
base salary remained the same. The Committee's failure to increase his base 
salary was because of financial exigencies within Hauser and was not based on 
inadequate performance.

         Dr. Stull's compensation is substantially related to the Company's 
performance because his compensation package includes a discretionary cash 
bonus determination and discretionary incentive stock options which are 
granted at 100% of fair market value, based upon the Compensation Committee's 
review of Dr. Stull's individual performance during the prior year in the 
following areas: leadership, strategic planning, business development, 
management skills, external relations and communication skills. During fiscal 
year 1998, Dr. Stull received incentive stock options to purchase 20,000 
shares of Common Stock which options vested on the date of grant.

         SUMMARY

         The Compensation Committee will continue to review Hauser's 
executive compensation programs to assure that such programs are consistent 
with the objective of providing a strong and direct link among shareholder 
value, Company performance and executive compensation.

By the Compensation Committee dated June 15, 1998

Dr. Bert M. Tolbert, Chairman
Dr. William E. Coleman, Director
Dr. Stanley J. Cristol, Director
Mr. Robert F. Saydah, Director

and by Dr. Dean P. Stull, Chief Executive Officer for the limited purposes 
stated above.

         Phantom Stock Plan was a bonus plan through which the individuals
         earned an equity interest in Shuster. The payments were made monthly.
         The individuals are also entitled to share in an earnout which may be
         paid to former shareholders of Shuster. No earnout was paid during
         1996, 1997 or 1998.
(8)      The amounts represent distributions from Shuster's Employee Stock
         Ownership Plan as a result of Hauser's acquisition and matching
         contributions from Shuster's 401(k) Plan.

STOCK OPTION PLANS

1987 NON-STATUTORY STOCK OPTION PLAN

         In 1987, Hauser adopted a non-statutory stock option plan (the 
"NON-STATUTORY PLAN") under which 718,720 shares of its Common Stock have 
been reserved for issuance. As of April 30, 1998, there were 813,237 shares 
of Common Stock committed under the Non-Statutory Plan. The Non-Statutory 
Plan was amended in 1997 to add 500,000 shares and extend the term to 2007.

         During fiscal year 1998, the Compensation Committee of the Board
(consisting of Drs. Tolbert, Coleman, Cristol and Mr. Saydah) recommended the
distribution of 154,849 stock options pursuant to the Non-Statutory Plan to
directors and to employees who had been employed over one-half time for one full
year. The options are exercisable for periods ranging from one to five years
after grant, at an exercise price [ranging] of 100% of market price on the date
of grant. The amount of the award was determined by using a percentage of that
employee's annual salary as of the employee's anniversary date with Hauser.
During fiscal year 1998, under the Non-Statutory Plan options to purchase 16,594
shares were exercised and options to purchase 26,856 shares expired.

         1992 INCENTIVE STOCK OPTION PLAN

         The 1992 Incentive Stock Option Plan (the "1992 PLAN"), as amended,
provides for the granting of incentive stock options to Executive Officers and
key employees of Hauser and its subsidiaries to purchase a maximum of 1,218,720
shares of the Common Stock. As of April 30, 1998, 439,162 shares were committed
under the 1992 Plan. The 1992 Plan provides for the grant of incentive stock
options intended to qualify as such under Section 422 of the Code. The exercise
price of options granted under the 1992 Plan may not be less than 100% of the
fair market value of the Common Stock at the time of the grant. Options are not
transferable and may not be exercised more than ten (10) years from the date of
grant. The aggregate fair market value of the stock with respect to which
incentive stock options are first exercisable in any calendar year may not
exceed $100,000. The 1992 Plan is administered by the Compensation Committee of
the Board, which has the authority to determine the persons to whom options will
be granted, the number of shares to be covered by each option, the time or times
at which options will be granted or exercised, and the term and provisions of
the options.

         The following chart compares the cumulative total return to
shareholders over the past five years for a holder of the Common Stock against
the cumulative total return of the NASDAQ Stock Market-US Index and the S & P
Chemicals (Specialty) Index. The chart depicts the value on April 30, 1998, of a
$100 investment made on April 30, 1993.

         The value of a stock over time is affected by many factors, including
Hauser's earnings. The decline in the stock price in August 1993 occurred after
Bristol-Myers Squibb Company failed to renew Hauser's contract. A primary
objective of Hauser since August 1993 has been to diversify into specialty
natural ingredients markets. Hauser's revenue mix is currently made up of sales
of pharmaceuticals, natural ingredients and technical services.

APPENDIX A


December 8, 1998

Board of Directors
Hauser, Inc.
5555 Airport Blvd.
Boulder, CO 80301

Members of the Board:

You have requested our opinion (the "Fairness Opinion"), as investment 
bankers, as to the fairness, from a financial point of view, to Hauser, Inc. 
(the "Company") and the stockholders of the Company of the consideration to 
be paid in connection with the proposed acquisitions via merger (the 
"Mergers") of  QQB Holdings I, Inc., QQB Holdings II, Inc., and QQB Holdings 
III, Inc., all wholly owned subsidiaries of the Company (collectively, the 
"Merger Subs"), respectively with and into Zuellig Botantical Extracts, Inc. 
("ZBE"), ZetaPharm, Inc. ("ZetaPharm"), and Wilcox Drug Company, Inc. 
("Wilcox") (collectively, the "Contributed Subsidiaries"), all directly or 
indirectly wholly owned subsidiaries of Zuellig Group, N.A., Inc. ("ZGNA"), 
pursuant to the draft Agreement and Plan of Merger dated December 7, 1998 
(the "Merger Agreement"), among, ZGNA, Zuellig Botanicals, Inc. ("ZBI"), the 
Contributed Subsidiaries, the Merger Subs and the Company. Adams, Harkness & 
Hill, Inc., as part of its investment banking activities, is continually 
engaged in the valuation of businesses and their securities in connection 
with mergers and acquisitions, negotiated underwritings, secondary 
distributions of listed and unlisted securities, private placements and 
valuations for corporate and other purposes.

At the Effective Time (as defined in the Merger Agreement), Merger Sub 1 
shall be merged with and into ZBE, Merger Sub 2 shall be merged with and into 
ZetaPharm, and Merger Sub 3 shall be merged with and into Wilcox.  Following 
the Effective Time, the separate corporate existence of the Merger Subs shall 
cease and ZBE, ZetaPharm and Wilcox each shall continue as the surviving 
corporations, each wholly owned by the Company.  As of the Effective Time, by 
virtue of the Mergers, the shares of capital stock of ZBE, ZetaPharm and 
Wilcox shall be cancelled and extinguished and converted into rights to 
cumulatively receive a number of common shares of the Company (the "Company 
Common Shares") equal to 0.49 multiplied by the quotient obtained by dividing 
the number of common shares of the Company outstanding immediately prior to 
the Closing (as defined in the Merger Agreement) by 0.51.

We are expressing no opinion as to what the value of the Company Common 
Shares will be when issued to ZGNA and ZBI pursuant to the Mergers or the 
prices at which the Company Common Shares will actually trade at any time.  
Our Fairness Opinion

as expressed herein is limited to the fairness, from a financial point of 
view, of the consideration paid by the Company and does not address the 
Company's underlying business decision to engage in the Mergers. 

In developing our Fairness Opinion, we have, among other things: (i) reviewed 
the Company's Annual Reports, Forms 10-K and related financial information 
for the three fiscal years ended April 31, 1998, and the Company's Form 10-Q 
and the related unaudited financial information for the six month period 
ending October 31, 1998; (ii) reviewed the audited financial statements of 
ZGNA, Wilcox and ZetaPharm for the three fiscal years ended March 31, 1998, 
and the audited financial statements of ZBI for the two fiscal years ended 
March 31, 1997; (iii) analyzed certain internal financial statements and 
other financial and operating data concerning the Company prepared by the 
management of the Company; (iv) analyzed certain internal financial 
statements and other financial and operating data concerning the Contributed 
Subsidiaries prepared by the management of ZGNA; (v) analyzed the potential 
pro forma financial effects of the Mergers on the Company and the Contributed 
Subsidiaries; (vi) conducted due diligence discussions with members of senior 
management of the Company and ZGNA and discussed with members of senior 
management of the Company and ZGNA their views regarding future business, 
financial and operating benefits arising from the Mergers; (vii) reviewed the 
historical market prices and trading activity for the Company Common Shares 
and compared them with those of certain publicly traded companies we deemed 
to be relevant and comparable to the Company and the Contributed 
Subsidiaries, respectively; (viii) compared the results of operations of the 
Company and the Contributed Subsidiaries with that of certain companies we 
deemed to be relevant and comparable to the Company and the Contributed 
Subsidiaries, respectively; (ix) compared the financial terms of the Mergers 
with the financial terms of certain other mergers and acquisitions we deemed 
to be relevant and comparable to the Mergers; (x) participated in certain 
discussions among representatives of the Company and ZGNA and their financial 
and legal advisors; (xi) reviewed the Merger Agreement and agreements which 
are Exhibits thereto; and (xii) reviewed such other financial studies and 
analyses and performed such other investigations and took into account such 
other matters as we deemednecessary, including our assessment of general 
economic, market and monetary conditions.

In connection with our review and arriving at our Fairness Opinion, we have 
not independently verified any information received from the Company or ZGNA, 
have relied on such information, and have assumed that all such information 
is complete and accurate in all material respects.  With respect to any 
internal forecasts reviewed relating to the prospects of the Company and the 
Contributed Subsidiaries, we have assumed that they have been reasonably 
prepared on bases reflecting the best currently available estimates and 
judgments of the Company's and ZGNA's management as to the future financial 
performance of the Company and the Contributed Subsidiaries.  Our Fairness 
Opinion is rendered on the basis of securities market conditions prevailing 
as of the date hereof and on the conditions and prospects, financial and

                                                              December 8, 1998
                                                                        Page 3

otherwise, of the Company and the Contributed Subsidiaries as known to us on 
the date hereof.  We have not conducted, nor have we received copies of, any 
independent valuation or appraisal of any of the assets of the Company and 
the Contributed Subsidiaries.  In addition, we have assumed, with your 
consent: (i) the Merger will be accounted for under the purchase method in 
accordance with generally accepted accounting principles as described in 
Accounting Principles Board Opinion Number 16; (ii) the Merger will 
constitute a tax-free reorganization under Section 368 of the Internal 
Revenue Code of 1986, as amended; and (iii) any material liabilities 
(contingent or otherwise, known or unknown) of the Company and the 
Contributed Subsidiaries are as set forth in the financial statements of the 
Company and the Contributed Subsidiaries, respectively. 

It is understood that this letter is for the information of the Board of 
Directors of the Company and may not be used for any other purpose without 
our prior written consent, except that this opinion may be included in its 
entirety in any filing made by the Company with the Securities and Exchange 
Commission with respect to the transactions contemplated by the Merger 
Agreement.

Based upon and subject to the foregoing, it is our opinion that, as of the 
date hereof, the consideration is fair, from a financial point of view, to 
the Company and the Company's stockholders.

Sincerely,

ADAMS, HARKNESS & HILL, INC.

the giving of notice would give rise to liability under any Environmental 
Law; (viii) to the best of the Company's knowledge, there are no ongoing

not misleading.  The audited consolidated financial statements and unaudited 
interim financial statements of the Company included in the Company SEC

requirements of the Securities Act and with the published rules and 
regulations of the Commission with respect thereto.  The financial statements

<PAGE>

respects in accordance with the books of account and records of the Company 
except as indicated therein.

              4.11.  ABSENCE OF CERTAIN DEVELOPMENTS.

              Except as disclosed in the Company SEC Reports, since April 30, 
1998, there has been no (i) change or event which could reasonably be 
expected to have a Company Material Adverse Effect (other than general trends 
or new laws, rules, or regulations applicable to similarly situated 
companies), (ii) declaration, setting aside or payment of any dividend or 
other distribution with respect to the capital stock of the Company, (iii) 
issuance of capital stock (other than pursuant to the exercise of options,

as directors in accordance with the historical arrangement), (iv) material 
loss, destruction or damage to any property of the Company or any Subsidiary,

Company in the ordinary course of business, (ix) acquisition, material 
writedown or write-off for accounting purposes or disposition of any material 
assets (or any contract or arrangement therefor) other than a possible sale 
or writedown of the paclitaxel business and assets, (x) redemption or 
repurchase of any capital stock of the Company, or any other material 
transaction by the Company or any Subsidiary otherwise than for fair value in 
the ordinary course of business or (xi) termination of an agreement or 
arrangement which would be a Company Key Agreement or Instrument if in effect 
on the date hereof.

              4.12.  MATERIAL CONTRACTS.

              SECTION 4.12 OF THE COMPANY DISCLOSURE SCHEDULE sets forth a 
true and complete list of each Company Key Agreement and 

                                      -20-
<PAGE>

Instrument (oral or written) to which the Company or its Subsidiary is a 
party of its assets bound other than Company Key Agreements and Instruments 
(i) filed as an exhibit to a Company SEC Report and (ii) under which the 
Company has no further liabilities (whether accrued, absolute, contingent, 
liquidated or otherwise, whether due or to become due, whether or not known 
to the Company) or obligations as of the date hereof. Each Company Key 
Agreement and Instrument that is currently in effect, is valid, binding and 
enforceable against the Company or such Subsidiary and, to the Company's best 
knowledge, the other parties thereto, in accordance with its terms, and in 
full force and effect on the date hereof.  A true and complete copy of each 
Key Agreement and Instrument of the Company has been delivered or made 
available to ZGNA.  There is no breach, violation or default by the Company 
and no event (including, without limitation, the consummation of the 
transactions contemplated herein) which, with notice or lapse of time or 
both, would (i) constitute a breach, violation or default by the Company 
under any Company Key Agreement or Instrument, or (ii) give rise to any lien 
or right of termination, modification, cancellation, prepayment, suspension, 
limitation, revocation or acceleration against the Company under any Company 
Key Agreement or Instrument except for breaches, violations or defaults that 
would not have a Company Material Adverse Effect.  To the best of the 
Company's knowledge, no other party to any Company Key Agreement or 
Instrument is in material breach of any such Company Key Agreement or 
Instrument, no waiver or indulgence has been granted by any of the parties 
thereto and no party to any such Company Key Agreement and Instrument has 
repudiated any provision thereof.  The Company is not a party to, nor are any 
of its assets subject to, any guaranty, "make well" agreement or other 
arrangement to be responsible for the obligations of another, including any 
obligation to maintain the financial condition of another person.

              4.13.  ABSENCE OF UNDISCLOSED LIABILITIES.

              Neither the Company nor any of its Subsidiaries has any debt, 
obligation or liability (whether accrued, absolute, contingent, liquidated or 
otherwise, whether due or to become due, whether or not known to the Company) 
arising out of any transaction entered into at or prior to Closing, or any 
act or omission at or prior to Closing, or any state of facts existing at or 
prior to Closing, including Taxes with respect to or based upon transactions 
or events occurring at or prior to Closing, and including, without 
limitation, unfunded past service liabilities 

                                      -21-
<PAGE>

under any pension, profit sharing or similar plan, except liabilities 
disclosed in the Company SEC Reports, current liabilities incurred since 
April 30, 1998, current obligations (other than as a result of breach or 
default) under agreements set forth on SECTION 4.12 OF THE COMPANY DISCLOSURE 
SCHEDULE, and obligations under agreements which are not required to be set 
forth on such schedule entered into in the usual and ordinary course of 
business, none of which (individually or in the aggregate) could have a 
Company Material Adverse Effect.

           4.14.     EMPLOYEES.

              (a)    The Company and its Subsidiaries are in full compliance 
with all laws regarding employment, wages, hours, equal opportunity, 
collective bargaining and payment of social security and other taxes except 
to the extent that noncompliance would not have a Company Material Adverse 
Effect.  Since January 1, 1997, no complaint of any unfair labor practice or 
discriminatory employment practice against the Company or any Subsidiary has 
been filed or, to the best of the Company's knowledge, threatened to be filed 
with or by the National Labor Relations Board, the Equal Employment 
Opportunity Commission or any other administrative agency, local, foreign, 
federal or state, that regulates labor or employment practices, nor is any 
grievance filed or, to the best of the Company's knowledge, threatened to be 
filed, against the Company or any Subsidiary by any employee pursuant to any 
collective bargaining or other employment agreement to which the Company or 
any Subsidiary is a party or is bound, except as would not reasonably be 
expected to have a Company Material Adverse Effect.  The Company and its 
Subsidiaries are in compliance with all applicable foreign, federal, state 
and local laws and regulations regarding occupational safety and health 
standards except to the extent that noncompliance will not have a Company 
Material Adverse Effect, and, since April 30, 1996, have received no 
complaints from any foreign, federal, state or local agency or regulatory 
body alleging violations of any such laws and regulations.  The Company is 
not bound or subject to any arrangement with any labor union, and, to the 
Company's best knowledge no union organizing activities are ongoing or 
threatened.

              (b)    All sums due for employee compensation and benefits and 
all vacation time owing to any employees of the Company or any of its 
Subsidiaries have been duly and adequately 

                                     -22-
<PAGE>

accrued on the accounting records of the Company and its Subsidiaries.

              (c)    The Company is not aware that any of its executive 
officers or persons whose principal occupation is the creation of 
intellectual property is obligated under any contract (including licenses, 
covenants or commitments of any nature) or other agreement, or subject to any 
judgment, decree or order of any court or administrative agency, that would 
interfere with the use of such executive officer's or person's best efforts 
to promote the interests of the Company or that would conflict with the 
Company's business as proposed to be conducted.

              (d)    The Company is not aware that any officer or key 
employee, or that any group of key employees, intends to terminate their 
employment with the Company, nor does the Company have a present intention to 
terminate the employment of any of the foregoing.

              (e)    Set forth on SECTION 4.14 OF COMPANY DISCLOSURE SCHEDULE 
is (i) a list of employees of the Company with an annual base compensation 
over $50,000, (ii) a list of all officers of the Company and (iii) a list of 
all employment agreements to which the Company is a party (copies of which 
have been delivered to ZGNA).

              4.15.  TAX MATTERS.

              There are no Taxes due and payable by the Company or any of its 
Subsidiaries which have not been paid except those being disputed in good 
faith by appropriate proceeding with appropriate reserves being made 
therefore on the accounting books of the Company.  The provisions for Taxes 
on the audited and unaudited balance sheets delivered by the Company to ZGNA 
will be sufficient for the payment in all material respects of all accrued 
and unpaid Taxes of the Company and its Subsidiaries, whether or not assessed 
or disputed in good faith as of the respective dates of such balance sheets.  
The Company and its Subsidiaries have duly filed or received extensions to 
filing all foreign, federal, state and local tax returns required to have 
been filed by them, and there are in effect no waivers of applicable statutes 
of limitations with respect to taxes for any year except where the failure to 
file such returns or the existence of waivers of applicable statutes of 
limitations is not reasonably likely to have a Company Material Adverse 
Effect.  All 

                                      -23-
<PAGE>

such returns (including those delivered by the Company to ZGNA) are true, 
complete and correct in all material respects and have been prepared from, 
and are in accordance with, the books and records of the Company and its 
Subsidiaries.  Neither the Company nor its Subsidiaries is a party to a Tax 
sharing agreement or liable for the Taxes of any other person.  Neither the 
Company nor its Subsidiaries have filed a consent to the application of 
Section 341(f) of the Code.  The Company and its Subsidiaries have made all 
estimated income tax deposits and all other required Tax payments or deposits 
and have complied for all prior periods with the Tax withholding provisions 
of all applicable foreign, federal, state and local laws applicable to them.  
Neither the Company nor any of its Subsidiaries has been subject to a 
foreign, federal or state tax audit since April 30, 1996.

       4.16.  EMPLOYEE BENEFIT PLANS.

               The Company and its Subsidiaries have no employee benefit 
plans (as defined in Section 3(3) of the Employee Retirement Income Security 
Act of 1974) covering former and current employees of the Company or any of 
its Subsidiaries, or under which the Company or any of its Subsidiaries has 
any obligation or liability.  SECTION 4.16 OF THE COMPANY DISCLOSURE SCHEDULE 
lists all material plans, contracts, bonuses, commissions, profit-sharing, 
savings, stock options, insurance, deferred compensation, or other similar 
fringe or employee benefits covering former or current employees of the 
Company or any of its Subsidiaries or under which the Company or any of its 
Subsidiaries has any obligation or liability (each, a "BENEFIT ARRANGEMENT"). 
True and complete copies of all Benefit Arrangements have been provided or 
made available to ZGNA prior to the date hereof.  The Benefit Arrangements 
are and have been administered in substantial compliance with their terms and 
with the requirements of applicable law.  No "prohibited transaction" within 
the meaning of Section 4475 of the Code or Section 406 of ERISA, has occurred 
with respect to any Benefit Arrangements. All payments to current or former 
employees of the Company or any of its Subsidiaries pursuant to the Benefit 
Arrangements are and have been fully deductible under the Code.

       4.17.  PATENTS, LICENSES, ETC.

              The Company or one of its Subsidiaries owns, free and clear of 
all encumbrances, restrictions, liens, security interests and charges, and 
has good and marketable title to, or 

                                     -24-
<PAGE>

holds adequate licenses or otherwise possesses all such rights as are 
necessary to use all patents (and applications therefor), patent disclosures, 
marks, trade names, copyrights (and applications therefor), inventions, 
discoveries, processes, know-how, scientific, technical, engineering and 
marketing data, formulae and techniques used or proposed to be used, in or 
necessary for the conduct of its business as now conducted (collectively, 
"INTELLECTUAL PROPERTY").

              Neither the Company nor any of its Subsidiaries has received 
notice nor has knowledge of any conflict or alleged conflict with the rights 
of others pertaining to the Intellectual Property described in this Section 
4.17 where the effect of such conflict could have a Company Material Adverse 
Effect.  To the Company's best knowledge, the Company's business, as 
presently conducted, and as proposed to be conducted, does not infringe upon 
or violate any patent rights, copyrights, marks, names, trade names or trade 
secrets of others.  To the Company's best knowledge, the Company and its 
Subsidiaries have the right to use all trade secrets, processes, customer 
lists and other rights incident to their respective businesses as now 
conducted.

              To the Company's best knowledge, no employee of the Company or 
any of its Subsidiaries has violated any employment agreement, non-compete 
agreement or proprietary information agreement which he or she had with a 
previous employer or other person, or any intellectual property policy of 
such employer, or is a party to or threatened by any litigation concerning 
any patents, marks, trade secrets, service names, trade names, copyrights, 
licenses and the like.

       4.18.  TITLE TO TANGIBLE ASSETS.

              The Company and its Subsidiaries have good title to their 
properties and assets and good title to all their leasehold estates, in each 
case subject to no mortgage, pledge, lien, lease, encumbrance or charge, 
other than or resulting from Taxes which have not yet become delinquent and 
minor liens and encumbrances which do not in any case materially detract from 
the value of the property subject thereto or materially impair the operations 
of the Company and its Subsidiaries and which have not arisen otherwise than 
in the ordinary course of business.

                                     -25-
<PAGE>

              4.19.  INSURANCE.

              The Company and its Subsidiaries and their respective 
properties are insured in such amounts, against such losses and with such 
insurers as are prudent when considered in light of the nature of the 
properties and businesses of the Company and its Subsidiaries and customary 
in light of the Company's exposure.  No notice of any termination, threatened 
termination, or denial of a material claim made since January 1, 1997, of, or 
under any of such policies has been received and such policies are in full 
force and effect.  A summary of all such policies, including whether they are 
on a "claims made" basis, is attached as SECTION 4.19 OF THE COMPANY 
DISCLOSURE SCHEDULE.  None of such policies will be terminated or reduced in 
coverage as a result of the transactions described herein.  All such policies 
are in full force and effect and all premiums with respect thereto have been 
paid.  The Company has not failed to give any notice or present any claim 
under any such insurance policy in due and timely fashion or as required by 
any of such insurance policies or has not otherwise, through any act, 
omission or non-disclosure, jeopardized or impaired full recovery of any 
claim under such policies, and there are no claims by the Company under any 
of such policies to which any insurance company is denying liability or 
defending under a reservation of rights or similar clause.

              4.20.  TRANSACTIONS WITH RELATED PARTIES.

              Neither the Company nor any Subsidiary is a party to any 
agreement with any of the Company's directors, officers or, to their best 
knowledge stockholders holding more than 1/2% of the Company's stock, or, to 
their best knowledge, any Affiliate or family member of any of the foregoing, 
including but not limited to, under which it:  (i) leases any real or 
personal property (either to or from such Person), (ii) licenses technology 
(either to or from such Person), (iii) is obligated to purchase any tangible 
or intangible asset from or sell such asset to such Person, (iv) purchases

under the registration, permit or qualification requirements of all 
applicable state securities laws.

              4.23.  INVESTMENT.

              (a)    The Company is acquiring the Subsidiary Shares for its

              (b)    The Company has such knowledge and experience in 
financial and business matters that it is capable of evaluating the merits 
and risks of its investment in the Contributed Subsidiaries as contemplated 
by this Agreement, and is able to bear the economic risk of such investment

such information and documents as it has requested and has been afforded an 
opportunity to ask questions of and receive answers from representatives of 
ZGNA and the Contributed Subsidiaries

              This Agreement, the Company Disclosure Schedules, and the other 
agreements, documents, certificates or written statements furnished or to be 
furnished to ZGNA through the Closing Date by or on behalf of the Company in 
connection with the transactions contemplated hereby taken as a whole, do not 
contain any untrue statement by the Company of a material fact or omit to 
state a material fact necessary to make the statements contained therein or 
herein, in light of the circumstances in which they were made, not 
misleading.  There is no fact which is known to the Company and which has not 
been disclosed herein or otherwise by the Company to ZGNA which is reasonably 
likely to have a Company Material Adverse Effect.  Projections and 

                                     -28-

forecasts prepared by or on behalf of the Company and delivered to ZGNA have

real property owned or leased by the Company and its Subsidiaries.  The 
Company and its Subsidiaries have title to its owned real properties 
(collectively, the "COMPANY OWNED REAL PROPERTIES") in each case, free and 
clear of all imperfections of title and all encumbrances, except for (i) 
those consisting of zoning or planning restrictions, easements, permits and 
other restrictions or limitations on the use of such property or 
irregularities in title thereto which, individually and in the aggregate, do 
not materially impair the use of such property, (ii) warehousemen's, 
mechanics', carriers', landlords', repairmen's or other similar encumbrances 
arising in the ordinary course of business and securing obligations not yet 
due and payable, (iii) other encumbrances which arise in the ordinary course 
of business and which individually and in the aggregate do not materially 
impair its use of such property or its ability to obtain financing by using 
such assets as collateral, (iv) any state of facts, including, without 
limitation, easements, encroachments or encumbrances, either shown by any 
survey or other inspection or granted by the Company prior to the date 
hereof, of such Company Owned Real Property which do not materially adversely 
interfere with the occupancy or use, as presently used or occupied, of such 
Company Owned Real Property, (v) liens for taxes and/or assessments not yet 
delinquent or which are being contested in good faith through appropriate 
proceedings, (vi) all rights or easements, if any, of any municipality or

                                     -29-

of all of the leases and subleases to which the Company is a party as 
described on SECTION 4.28 OF COMPANY'S DISCLOSURE SCHEDULE (collectively, the

Properties, the "COMPANY REAL PROPERTIES").  The leases and subleases 
described on SECTION 4.28 OF THE COMPANY DISCLOSURE SCHEDULE (i) have not 
been further modified or amended and (ii) are in full force and effect.  To 
the knowledge of the Company, there is no default which remains uncured and 
would materially adversely interfere with the occupancy or use, as presently 
used or occupied, of any Company Leased Real Property.  The Company is not 
obligated to purchase any Company Leased Real Property and no Company Leased 
Real Property is required to be accounted for under GAAP as a capitalized 
lease.

              5.12.  MATERIAL CONTRACTS.

              SECTION 5.12 OF ZGNA DISCLOSURE SCHEDULE sets forth a true and 
complete list of each Subsidiary Key Agreement and Instrument (oral or 
written) to which a Contributed Subsidiary is a party or its assets bound 
other than Subsidiary Key Agreements and Instruments under which each 
Contributed Subsidiary has no further liabilities (whether accrued, absolute, 
contingent, liquidated or otherwise, whether due or to become due, whether or 
not known to ZGNA or a Contributed Subsidiary) or obligations as of the date 
hereof.  Each Subsidiary Key Agreement and Instrument that is currently in 
effect, is valid, binding and enforceable against such Contributed Subsidiary 
and, to ZGNA's and Contributed Subsidiaries' best knowledge, the other 
parties thereto, in accordance with its terms, and in full force and effect 
on the date hereof.  A true and complete copy of each Subsidiary Key 
Agreement has been delivered or made available to the Company.  There is no 
breach, violation or default by any Contributed Subsidiary and no event 
(including, without limitation, the consummation of the transactions 
contemplated herein) which, with notice or lapse of time or both, would (i) 
constitute a breach, violation or default by any Contributed Subsidiary under 
any Subsidiary Key Agreement or Instrument, or (ii) give rise to any lien or 
right of termination, modification, cancellation, prepayment, suspension, 
limitation, revocation or acceleration against any Contributed Subsidiary 
under any Subsidiary Key Agreement or Instrument except for breaches, 
violations or defaults that would not have a Subsidiary Material Adverse 
Effect.  To the best of ZGNA's and the Contributed Subsidiaries' knowledge, 
no other party to any Subsidiary Key Agreement or Instrument is in material 
breach of any such Subsidiary Key Agreement or Instrument, no waiver or 
indulgence 

                                     -39-
<PAGE>

has been granted by any of the parties thereto and no party to any such 
Subsidiary Key Agreement and Instrument has repudiated any provision thereof. 
No Contributed Subsidiary is a party to, nor are any of their assets subject 
to, an guaranty, "make well" agreement or other arrangement to be responsible 
for the obligations of another, including any obligation to maintain the 
financial condition of another person.

              5.13.  ABSENCE OF UNDISCLOSED LIABILITIES.

              None of the Contributed Subsidiaries has any debt, obligation 
or liability (whether accrued, absolute, contingent, liquidated or otherwise, 
whether due or to become due, whether or not known to ZGNA or a Contributed 
Subsidiary) arising out of any transaction entered into at or prior to 
Closing, or any act or omission at or prior to Closing, or any state of facts 
existing at or prior to Closing, including Taxes with respect to or based 
upon transactions or events occurring at or prior to Closing, and including, 
without limitation, unfunded past service liabilities under any pension, 
profit sharing or similar plan, except as disclosed in the CS Balance Sheets, 
current liabilities incurred since the date of the CS Balance Sheet, current 
obligations (other than as a result of breach or default) under agreements 
set forth on SECTION 5.12 OF ZGNA DISCLOSURE SCHEDULE, and obligations under 
agreements which are not required to be set forth on such schedule entered 
into in the usual and ordinary course of business, none of which 
(individually or in the aggregate) could have a Subsidiary Material Adverse 
Effect.

              5.14.  EMPLOYEES.

              (a)    The Contributed Subsidiaries are in full compliance with 
all laws regarding employment, wages, hours, equal opportunity, collective 
bargaining and payment of social security and other taxes except to the 
extent that noncompliance would not have a Subsidiary Material Adverse 
Effect.  Since January 1, 1998, no complaint of any unfair labor practice or 
discriminatory employment practice against the Contributed Subsidiaries has 
been filed or, to the best of ZGNA's and the Contributed Subsidiaries' 
knowledge, threatened to be filed with or by the National Labor Relations 
Board, the Equal Employment Opportunity Commission or any other 
administrative agency, local, foreign, federal or state, that regulates labor 
or employment practices, nor is any grievance filed or, to the best of ZGNA's 
and the Contributed Subsidiaries' knowledge, threatened to be 

                                     -40-
<PAGE>

filed, against any Contributed Subsidiary by any employee pursuant to any 
collective bargaining or other employment agreement to which any Contributed 
Subsidiary is a party or is bound, except as would not reasonably be expected 
to have a Subsidiary Material Adverse Effect.  The Contributed Subsidiaries 
are in compliance with all applicable foreign, federal, state and local laws 
and regulations regarding occupational safety and health standards except to 
the extent that noncompliance will not have a Subsidiary Material Adverse 
Effect, and, since January 1, 1997, have received no complaints from any 
foreign, federal, state or local agency or regulatory body alleging 
violations of any such laws and regulations.  No Contributed Subsidiary is 
bound or subject to any arrangement with any labor union, and, to ZGNA's and 
Contributed Subsidiaries' best knowledge no union organizing activities are 
ongoing or threatened.

              (b)    All sums due for employee compensation and benefits and 
all vacation time owing to any employees of the Contributed Subsidiaries have 
been duly and adequately accrued on the accounting records of the Contributed 
Subsidiaries.

              (c)    ZGNA and the Contributed Subsidiaries are not aware that 
any of the Contributed Subsidiaries' executive officers or persons whose 
principal occupation is the creation of intellectual property is obligated 
under any contract (including licenses, covenants or commitments of any 
nature) or other agreement, or subject to any judgment, decree or order of 
any court or administrative agency, that would interfere with the use of such 
executive officer's or person's best efforts to promote the interests of the 
Contributed Subsidiaries or that would conflict with the Contributed 
Subsidiaries' business as proposed to be conducted.

              (d)    ZGNA and the Contributed Subsidiaries are not aware that 
any officer, key employee, key purchasing personnel anticipated to provide 
sourcing of biomass under the Sourcing Agency Agreement or key sales 
personnel anticipated to engage in sales under the Agreement Regarding 
Employees or that any group of such employees, intends to terminate their 
employment with any Contributed Subsidiary, nor does any Contributed 
Subsidiary have a present intention to terminate the employment of any of the 
foregoing.

              (e)    Set forth on SECTION 5.14 OF ZGNA DISCLOSURE SCHEDULE is 
(i) a list of employees of a Contributed Subsidiary 

                                     -41-
<PAGE>

with an annual base compensation over $50,000, (ii) a list of all officers of 
a Contributed Subsidiary and (iii) a list of all employment agreements to 
which a Contributed Subsidiary is a party (copies of which have been 
delivered to the Company).

              5.15.  TAX MATTERS.

              There are no Taxes due and payable by the Contributed 
Subsidiaries which have not been paid except those being disputed in good 
faith by appropriate proceeding with appropriate reserves being made 
therefore on the accounting books of the Contributed Subsidiaries.  The 
provisions for Taxes on the audited and unaudited balance sheets delivered by 
ZGNA and the Contributed Subsidiaries to the Company will be sufficient for 
the payment in all material respects of all accrued and unpaid Taxes of the 
Contributed Subsidiaries, whether or not assessed or disputed in good faith 
as of the respective dates of such balance sheets.  The Contributed 
Subsidiaries have duly filed or received extensions to filing all foreign, 
federal, state and local Tax returns required to have been filed by them, and 
there are in effect no waivers of applicable statutes of limitations with 
respect to taxes for any year except where the failure to file such returns 
or the existence of waivers of applicable statutes of limitations is not 
reasonably likely to have a Subsidiary Material Adverse Effect.  All such 
returns (including those delivered by ZGNA to the Company) are true, complete 
and correct in all material respects and have been prepared from, and are in 
accordance with, the books and records of each.  No Contributed Subsidiary is 
a party to a Tax sharing agreement or liable for the Taxes of any other 
person.  No Contributed Subsidiary has filed a consent to the application of 
Section 341(f) of the Code.  The Contributed Subsidiaries have made all 
estimated income tax deposits and all other required Tax payments or deposits 
and have complied for all prior periods with the Tax withholding provisions 
of all applicable foreign, federal, state and local laws applicable to them.  
None of the Contributed Subsidiaries has been subject to a foreign, federal 
or state tax audit since April 30, 1996.

              5.16.  EMPLOYEE BENEFIT PLANS.

               Except as set forth on SECTION 5.16 OF ZGNA DISCLOSURE 
SCHEDULE, the Contributed Subsidiaries have no employee benefit plans (as 
defined in Section 3(3) of ERISA) covering former and current employees of 
the Contributed Subsidiaries, or under 

                                     -42-
<PAGE>

which a Contributed Subsidiary has any obligation or liability.  SECTION 5.16 
OF ZGNA DISCLOSURE SCHEDULE lists all material plans, contracts, bonuses, 
commissions, profit-sharing, savings, stock options, insurance, deferred 
compensation, or other similar fringe or employee benefits covering former or 
current employees of the Contributed Subsidiaries or under which the 
Contributed Subsidiaries have any obligation or liability.  True and complete 
copies of all Benefit Arrangements have been provided or made available to 
the Company prior to the date hereof.  The Benefit Arrangements are and have 
been administered in substantial compliance with their terms and with the 
requirements of applicable law.  No "prohibited transaction" within the 
meaning of Section 4475 of the Code or Section 406 of ERISA, has occurred 
with respect to any Benefit Arrangements.  All payments to current or former 
employees of the Contributed Subsidiaries pursuant to the Benefit 
Arrangements are and have been fully deductible under the Code.

              5.17.  PATENTS, LICENSES, ETC.

              The Contributed Subsidiaries own, free and clear of all 
encumbrances, restrictions, liens, security interests and charges, and has 
good and marketable title to, or holds adequate licenses or otherwise 
possesses all such rights as are necessary to use all Intellectual Property.  
To the knowledge of ZGNA and ZBI, one or more of the Contributed Subsidiaries 
has the right to use the names "Zuellig Botanicals" (but not "Zuellig 
Botanicals Powders"), and "ZetaPharm" as a trade name or mark for the 
purposes for which they have been used in the United States.  Set forth on 
Section 5.17 of ZGNA Disclosure Schedule is a list of the significant marks 
and names used by each Contributed Subsidiary.

              None of the Contributed Subsidiaries has received notice nor 
has knowledge of any conflict or alleged conflict with the rights of others 
pertaining to the Intellectual Property described in this Section 5.17 where 
the effect of such conflict could have a Subsidiary Material Adverse Effect.  
To ZGNA's and the Contributed Subsidiaries' best knowledge, the Contributed 
Subsidiaries' business, as presently conducted, and as proposed to be 
conducted, does not infringe upon or violate any patent rights, copyrights, 
marks, names, trade names or trade secrets of others.  To ZGNA's and the 
Contributed Subsidiaries' best knowledge, the Contributed Subsidiaries have 
the right to use all trade secrets, processes, customer lists 

                                     -43-
<PAGE>

and other rights incident to their respective businesses as now conducted.

              To ZGNA's and the Contributed Subsidiaries' best knowledge, no 
employee of the Contributed Subsidiaries has violated any employment 
agreement, non-compete agreement, or proprietary information agreement which 
he or she had with a previous employer or other person, or any intellectual 
property policy of such employer, or is a party to or threatened by any 
litigation concerning any patents, marks, trade secrets, service names, trade 
names, copyrights, licenses and the like.

              5.18.  TITLE TO TANGIBLE ASSETS.

              The Contributed Subsidiaries have good title to their 
properties and assets and good title to all their leasehold estates, in each 
case subject to no mortgage, pledge, lien, lease, encumbrance or charge, 
other than or resulting from Taxes which have not yet become delinquent and 
minor liens and encumbrances which do not in any case materially detract from 
the value of the property subject thereto or materially impair the operations 
of the Contributed Subsidiaries and which have not arisen otherwise than in 
the ordinary course of business.

              5.19.  INSURANCE.

              The Contributed Subsidiaries and their respective properties 
are insured in such amounts, against such losses and with such insurers as 
are prudent when considered in light of the nature of the properties and 
businesses of the Contributed Subsidiaries and customary in light of such 
Contributed Subsidiaries' exposure.  No notice of any termination or 
threatened termination, or denial of a material claim made since January 1, 
1997, of, or under any of such policies has been received and such policies 
are in full force and effect. A summary of all such policies, including 
whether they are on a "claims made" basis, is attached as SECTION 5.19 OF 
ZGNA DISCLOSURE SCHEDULE.  None of such policies will be terminated or 
reduced in coverage as a result of the transactions described herein.  All 
such policies are in full force and effect and all premiums with respect 
thereto have been paid.  No Contributed Subsidiary has failed to give any 
notice or present any claim under any such insurance policy in due and timely 
fashion or as required by any of such insurance policies or has not 
otherwise, through any act, omission or non-disclosure, jeopardized or 

                                     -44-

claims by any Contributed Subsidiary under any of such policies to which any 
insurance company is denying liability or defending under a reservation of 
rights or similar clause.

              5.20.  TRANSACTIONS WITH RELATED PARTIES.

              None of the Contributed Subsidiaries is a party to any

reflecting the foregoing restrictions on the transfer of such securities:

              "The securities evidenced hereby have not been registered under

              securities law, and may not be sold, transferred or otherwise
              disposed of except pursuant to an effective registration under the
              Act or in a transaction which, in the opinion of counsel
              reasonably acceptable to the Company, is exempt from such
              registration."

              "The securities evidenced hereby are subject to the terms of that
              certain Governance Agreement, dated as of _____________, 1999, by
              and among the Company, ZGNA and

              6.10.  OWNERSHIP OF SHARES.

and ZBI agree to continue to own its portion of the Shares or other Liquid
Assets of approximately equivalent value to its portion of the Shares until the
later of (i) the second anniversary of the Closing Date, or (ii) in the event
the Company asserts any claims pursuant to Section 9.4(b)(i), until the final
resolution of such claims.  For purposes hereof, the term "Liquid Assets" shall
mean cash, money market funds, commercial paper of 


                                    -58-
<PAGE>

a U.S. based entity, or securities that are publicly traded on the New York 
Stock Exchange, the American Stock Exchange or the Nasdaq National Market.

              (b)  Notwithstanding the foregoing subsection (a), after the first
anniversary of the Closing Date, ZGNA's and ZBI's obligation to hold its portion
of the Shares or other Liquid Assets of approximately equivalent value to its
portion of the Shares shall be reduced to 60% of the initial value of its
portion of the Shares plus an amount equal to the value of the claims made,
asserted or pending under Section 9 as of such date.

              (c)  In the event the Company, ZBI or ZGNA shall be required to
make an indemnification payment pursuant to Section 9, they may elect to make
such payment with the shares of Common Stock in lieu of cash.  The market price
of the shares of Common Stock shall be determined by the average closing price
of a share of Common Stock for the 15 consecutive trading days preceding the
date of such payment on the principal national securities exchange on which the
shares of Common Stock are listed or admitted to trading or, if not listed or
admitted to trading on any national securities exchange, the average of the
reported bid and asked prices during such 15 consecutive trading days on the
Nasdaq National Market or, if the shares are not listed on the Nasdaq National
Market, in the over-the-counter market or, if the shares of Common Stock are not
publicly traded, the market price for such day shall be the fair market value
thereof determined jointly by the Company and ZGNA; PROVIDED, HOWEVER, that if
such parties are unable to reach agreement within a reasonable period of time,
the market price shall be determined in good faith by an independent investment
banking firm selected jointly by the Company and ZGNA or, if that selection
cannot be made within 15 days, by an independent investment banking firm
selected by the American Arbitration Association in accordance with its rules. 
All costs and expenses incurred in connection with the determination of market
price shall be borne by the party seeking to make payment in stock.

              6.11.  NONCOMPETITION.

              (a)  ZGNA shall not, and shall cause its parent corporation and
its Affiliates, for a period of five (5) years following the Closing Date, for
any reason whatsoever, directly or indirectly, or on behalf of or in conjunction
with any other person:


                                    -59-
<PAGE>

                     (i)    engage in any business selling any products or
services in direct competition with the Company, including, but not limited to,
the Contributed Subsidiaries, in North America as conducted as of the Closing
Date; 

                     (ii)   engage in the business of acquiring biomass also
used by the Company for the purpose of retail or wholesale sales in North
America (including after processing) for use as a human nutraceutical; or

                     (iii)  solicit any person who is an employee of the
Company, including, but not limited to the Contributed Subsidiaries, in a
managerial, sales or purchasing capacity for the purpose or with the intent of
enticing such employee away from or out of employ of the Company or its
Subsidiaries.

              (b)  Notwithstanding the above, the foregoing covenant shall not
prohibit ZGNA from acquiring as an investment not more than five percent (5%) or
continuing to own no more than the percentage ZGNA owns on the date of this
Agreement of the capital stock of a competing business, provided that ZGNA shall
not control such competing business.

              (c)  If any provision of this Section 6.11 relating to a time
period or geographic area shall be declared by a court of competent jurisdiction
unenforceable as unreasonable, the maximum time period or geographic area, as
applicable, that such court deems reasonable and enforceable shall thereafter be
deemed applicable and this Agreement shall automatically be considered to have
been amended and revised to reflect such determination.  This Section 6.11 may
be enforced by specific performance.

              6.12.  RESIGNATION OF DIRECTORS.

              Effective as of the Closing Date, all directors of each
Contributed Subsidiary shall cease to be directors.  ZGNA will use its good
faith effort to obtain the resignation of all directors of each Contributed
Subsidiary.

              6.13.  SUBSCRIPTION RIGHT.

              (a)    If at any time after the date hereof, the Company proposes
to issue equity securities of any kind (the term "equity securities" shall
include for these purposes any warrants, options or other rights to acquire
equity securities and debt securities convertible into equity securities) of the
Company 


                                    -60-

underwriting pursuant to a registration statement filed under the Securities 
Act, (ii) pursuant to the acquisition of another entity by the Company by 
merger, purchase of substantially all of the assets or stock or other form of 
acquisition, (iii) pursuant to an employee, consultant or director stock

       optional or other special rights, and the qualification, limitations or
       restrictions thereof and interest rate and maturity; (2) the price and
       other terms of the proposed sale of such securities; (3) the amount of
       such securities proposed to be issued; and (4) such other information as
       ZGNA may reasonably request in order to evaluate the proposed issuance;
       and

                (ii) offer to issue to ZGNA upon the terms described in
       subparagraph (i) above a portion of the Proposed Securities (the

Section 6.13 shall terminate (i) if this Agreement is terminated in accordance

Date.

              (f)    The exercise by ZGNA of its rights under this Section 6.13

Effect or a Subsidiary Material Adverse Effect, it shall promptly notify the
other party including informing it of the nature of such company's Material

efforts to defend against such claim, action, investigation or governmental
action, and seek the removal of any injunction preventing or

indemnification by the Company for any Damages arising from any matter of 
which ZGNA had knowledge at or prior to Closing by reason of the Company 
having delivered written notice thereto, either in a supplemented disclosure 
schedule or an officer's certificate, at or prior to Closing, if (i) the 
conditions to ZGNA's obligation set forth in Section 7 fail to be satisfied 
at Closing by reason of the matters disclosed in such supplemented disclosure 
schedule or officer's certificate and ZGNA waives its right not to Close 
unless (ii) the Company made a knowing misrepresentation with respect to such 
matter on the date of this Agreement; PROVIDED that clause (i) above shall 
not apply in respect of any matter as to which the Company has the explicit 
right set forth in Section 4 to notify ZGNA thereof at or prior to Closing 
and modify the corresponding disclosures.

              (f)  Notwithstanding anything herein to the contrary, none of the
Company Indemnified Parties shall be entitled to indemnification by ZGNA for any
Damages arising from any matter of which the Company had knowledge at or prior
to Closing by reason of ZGNA having delivered written notice thereto, either in
a supplemented disclosure schedule or an officer's certificate, at or prior to
Closing, if (i) the conditions to the Company's obligation set forth in Section
8 fail to be satisfied at Closing by reason of the matters disclosed in such
supplemented disclosure schedule or officer's certificate and the Company waives
its right not to Close unless (ii) ZGNA made a knowing misrepresentation with
respect to such matter on the date of this Agreement; PROVIDED that clause (i)
above shall not apply in respect of any matter as to which ZGNA has the explicit
right set forth in Section 5 to notify the Company thereof at or prior to
Closing and modify the corresponding disclosures.

              (g)  Any calculation of Damages for purposes of this Section 9.4
shall be (i) net of any insurance recovery made by the Indemnified Party
(whether paid directly to such Indemnified Party or assigned by the Indemnifying
Party to such Indemnified Party) and (ii) reduced to take account of any net Tax
benefit realized by the Indemnified Party arising from the deductibility of any
such Damages or Tax.  Any indemnification payment hereunder shall initially be
made without regard to this paragraph and shall be reduced to reflect any such
net Tax benefit only after the Indemnified Party has actually realized such
benefit.  For purposes of this Agreement, an Indemnified Party shall be deemed
to have "actually realized" a net Tax benefit to the extent that, and at such
time as, the amount of 


                                    -74-
<PAGE>

Taxes payable by such Indemnified Party is reduced below the amount of Taxes 
that such Indemnified Party would have been required to pay but for 
deductibility of such Damages.  The amount of any reduction hereunder shall 
be adjusted to reflect any final determination (which shall include the 
execution of Form 870-AD or successor form) with respect to the Indemnified 
Party's liability for Taxes and, if necessary, the Company or ZGNA and ZBI, 
as the case may be, shall make payments to the other to reflect such 
adjustment. Any indemnity payment under this Agreement shall be treated as an 
adjustment to the consideration for Tax purposes, unless a final 
determination (which shall include the execution of a Form 870-AD or 
successor form) with respect to the Indemnified Party or any of its 
Affiliates causes any such payment not to be treated as an adjustment to the 
consideration for U.S. Federal income Tax purposes.

              (h)  No action, claim or setoff for Damages subject to
indemnification under this Section 9.4 shall be brought or made:

               (i)  with respect to claims for Damages resulting from a breach
of any covenant contained in this Agreement after the date on which such
covenant shall terminate pursuant to Section 9.3 hereof; and

               (ii)  with respect to claims for Damages resulting from a breach
of any representation or warranty, after the date on which such representation
or warranty shall terminate pursuant to Section 9.3 hereof;

PROVIDED, HOWEVER, that any claim made with reasonable specificity by the party
seeking indemnification (the "INDEMNIFIED PARTY") to the party from which
indemnification is sought (the "INDEMNIFYING PARTY") within the time periods set
forth above shall survive (and be subject to indemnification) until it is
finally and fully resolved.

              (i)  Upon receipt by the Indemnified Party of notice of any
action, suit, proceedings, claim, demand or assessment against such Indemnified
Party which might give rise to a claim for Damages, the Indemnified Party shall
give written notice thereof to the Indemnifying Party indicating the nature of
such claim and the basis therefor; PROVIDED, HOWEVER, that failure to give such
notice shall not affect the indemnification provided hereunder except to the
extent the Indemnifying Party shall have 


                                    -75-
<PAGE>

been actually prejudiced as a result of such failure.  A claim to indemnity 
hereunder may, at the option of the Indemnified Party, be asserted as soon as 
Damages have been threatened by a third party orally or in writing, 
regardless of whether actual harm has been suffered or out-of-pocket expenses 
incurred, PROVIDED the Indemnified Party shall reasonably determine that it 
may be liable or otherwise incur such Damages.  The Indemnifying Party shall 
have the right, at its option, to assume the defense of, at its own expense 
and by its own counsel, any such matter involving the asserted liability of 
the Indemnified Party as to which the Indemnifying Party shall have 
acknowledged its obligation to indemnify the Indemnified Party.  If any 
Indemnifying Party shall undertake to compromise or defend any such asserted 
liability, it shall promptly notify the Indemnified Party of its intention to 
do so, and the Indemnified Party agrees to cooperate fully with the 
Indemnifying Party and its counsel in the compromise of, or defense against, 
any such asserted liability; PROVIDED, HOWEVER, that the Indemnifying Party 
shall not settle any such asserted liability without the written consent of 
the Indemnified Party (which consent will not be unreasonably withheld); 
PROVIDED, FURTHER, however that the immediately preceding clause shall not 
apply in the case of relief consisting solely of money damages at least 80% 
of which shall be borne by the Indemnifying Party after taking into account 
any limitation thereon.  Notwithstanding an election to assume the defense of 
such action or proceeding, such Indemnified Party shall have the right to 
employ separate counsel and to participate in the defense of such action or 
proceeding, and the Indemnifying Party shall bear the reasonable fees, costs 
and expenses of such separate counsel (and shall pay such fees, costs and 
expenses at least quarterly), if (A) the use of counsel chosen by the 
Indemnifying Party to represent such Indemnified Party would present such 
counsel with a conflict of interest; (B) the defendants in, or targets of, 
any such action or proceeding include both an Indemnified Party and the 
Indemnifying Party, and such Indemnified Party shall have reasonably 
concluded that there may be legal defenses available to it or to other 
Indemnified Parties which are different from or additional to those available 
to the Indemnifying Party (in which case the Indemnifying Party shall not 
have the right to direct the defense of such action or proceeding on behalf 
of the Indemnified Party); (C) the Indemnifying Party shall not have employed 
counsel reasonably satisfactory to such Indemnified Party to represent such 
Indemnified Party within a reasonable time after notice of the institution of 
such action or proceeding; or (D) the Indemnifying Party shall authorize such 
Indemnified Party to employ separate 


                                    -76-
<PAGE>

counsel at the Indemnifying Party's expense.  In any event, the Indemnified 
Party and its counsel shall cooperate with the Indemnifying Party and its 
counsel and shall not assert any position in any proceeding inconsistent with 
that asserted by the Indemnifying Party.  All costs and expenses incurred in 
connection with an Indemnified Party's cooperation shall be borne by the 
Indemnifying Party.  In any event, the Indemnified Party shall have the right 
at its own expense to participate in the defense of such asserted liability.

              (j)  The sole and exclusive remedy for any breach of any
representation, warranty, covenant or agreement shall be pursuant to this
Section 9.4, except in the case of fraud.  Absent fraud, under no circumstances
shall either party be liable to other for consequential or punitive damages.

              (k)  Each party hereby acknowledges and agrees that the other
party is not making any representation or warranty whatsoever, express or
implied, including, without limitation, in respect of their respective assets,
liabilities and businesses, except those representations and warranties
explicitly set forth in the Transaction Document or in any certificate
contemplated hereby and delivered in connection herewith.

               9.5.  BREAK-UP FEE.

              (a)  In the event that (i) upon a vote at a duly held meeting of
the stockholders of the Company or any adjournment thereof, any stockholder
approval contemplated by this Agreement shall not have been approved or (ii) the
Board shall have withdrawn, modified or amended (or resolved to withdraw, modify
or amend) in any respect its recommendation to its stockholders that this
Agreement be approved by the Company's stockholders, the Company shall pay ZGNA
all of ZGNA's reasonable out-of-pocket expenses incurred in connection with the
transactions contemplated hereby, including fees and expenses of its counsel and
financial advisors; provided, that the Company shall not be liable for 
out-of-pocket expenses in excess of $500,000.

              (b)  If within twelve (12) months of the termination date of this
Agreement for either of the reasons set forth in 9.5(a) the Company shall sell
such number of shares of Common Stock equal to or greater than 49% of the issued
and outstanding shares of the Common Stock (calculated by using the number of
issued and outstanding shares of Common Stock as of the date 


                                    -77-
<PAGE>

hereof) by way of sale of securities, merger, reorganization, or shall sell 
all or substantially all of its assets, the Company shall pay $1,500,000 (the 
"TERMINATION FEE") to ZGNA in immediately available funds no later than two 
(2) Business Days after entry into such agreement.  The Company agrees that 
it will not structure any transaction or agreement for the purpose of 
avoiding payment of Termination Fee. The Company acknowledges that the 
agreements contained in this Section 9.5 are an integral part of the 
transactions contemplated in this Agreement, and that, without these 
agreements, ZGNA would not enter into this Agreement; accordingly, if the 
Company fails to promptly pay the amount due pursuant to this Section 9.5, 
and, in order to obtain such payment, ZGNA commences a suit which results in 
a judgment against the Company for the Termination Fee, the Company shall pay 
to ZGNA its costs and expenses (including attorneys' fees) in connection with 
such suit, together with interest on the amount of the fee at the prime rate 
of Citibank, N.A. on the date such payment was required to be made. 
Notwithstanding the foregoing, no Termination Fee or payment under Section 
9.5(a) shall be payable if the transactions contemplated hereunder are not 
consummated because (i) the Company's Board of Directors withdraws its 
recommendation of this Agreement as a result of a material breach or 
misrepresentation by ZGNA, (ii) the Company or ZGNA failed to enter into a 
definitive credit agreement with their respective lenders, (iii) the Company 
terminates this Agreement because of a material breach (including a material 
breach of Section 6.9 herein) or a material misrepresentation by ZGNA, (iv) 
approval under the HSR is not obtained (assuming the Company and ZGNA have 
made appropriate HSR filings) or (v) the Company terminates this Agreement as 
a result of failure to satisfy Sections 8.3 (Injunction), 8.6 (Adverse 
Development), 8.10 (Transaction Documents), 8.11 (ZGNA's Certificates), 8.12 
(Counsel's Opinion), 8.13 (Completion of Mergers) or 8.16 (Sales Force).

              (c)  Notwithstanding, in the event ZGNA shall have exercised the
Option and shall thereafter sell the shares of Common Stock received by it upon
exercise of the Option, ZGNA shall pay to the Company any fees and expenses
(including Termination Fee) received by it pursuant to this Section to the
extent the net proceeds received by it in connection with such sale exceed the
exercise price for the Option.

               10.8. THIRD PARTIES.

              Nothing contained in this Agreement or in any instrument or
document executed by any party in connection with the transactions contemplated
hereby shall create any rights in, or be deemed to have been executed for the

permitted assign of such a party.

               10.9. ARBITRATION.
                 
              
(a)    The parties shall initially attempt to resolve by direct negotiation any
dispute, controversy or claim arising out of or relating to (i) this Agreement
or the other Transaction Documents, (ii) its or their breach, interpretation,
termination or validity, or (iii) the transactions contemplated hereby or
thereby (each, a "DISPUTE").

              (b)    If the parties are not able to settle the Dispute by direct
negotiations within thirty (30) days after written notice by one party to the
other of the Dispute, any party may initiate an arbitration to resolve the
Dispute; the parties hereto agree that arbitration pursuant to this Section
shall be the sole means of resolving Disputes, and that no party shall commence
any proceeding in any court or tribunal with respect to a Dispute.  All such
Disputes shall be arbitrated in Denver, Colorado pursuant to the Commercial
Arbitration Rules of the American Arbitration Association except that the
parties expressly do not constitute the American Arbitration Association as
administrator of the arbitration as provided in Rule 3 of such Rules and the
arbitration shall be administered by the Chair of the Panel.  Each of the
Company, on the one hand, and ZGNA and ZBI, on the other hand, shall select an
arbitrator, and the two arbitrators shall select a third arbitrator.  The third
arbitrator shall act as Chair of the panel.  The arbitrators shall be certified
public accountants, attorneys or other persons, in each case, who are
experienced in the buying and selling of businesses.  If the two arbitrators
fail to agree upon the appointment of a third arbitrator within 30 days, the
American Arbitration Association shall appoint the third arbitrator.

              (c)    Judgment upon any award rendered by the arbitrator(s),
which may include specific performance of the 


                                    -81-
<PAGE>

obligations of the parties under this Agreement, shall be binding and may be 
entered in any court having jurisdiction.  Nothing in this Section shall 
preclude any party from seeking temporary or preliminary injunctive equitable 
relief from a court of competent jurisdiction and Section 10.9(a) and (b) 
shall not apply in that situation.  No such court order shall stay or 
otherwise impede the arbitration proceeding.  The statute of limitations, 
estoppel, waiver, laches, and similar doctrines, which would otherwise be 
applicable in any action brought by a party shall be applicable in any 
arbitration proceeding and the commencement of an arbitration proceeding 
shall be deemed the commencement of an action for those purposes. The Federal 
Arbitration Act shall apply to the construction, interpretation and 
enforcement of this arbitration provision.

              (d)    Nothing in this Agreement shall preclude the arbitrator(s)
from rendering an interim award (which may include equitable relief) which may
be enforced by the parties hereto as though a final award.

              (e)    The Company, on the one hand, and ZGNA and ZBI, on the
other hand, shall jointly and equally bear all arbitration expenses, provided,
however, that any legal fees or expenses incurred by any party in connection
with such arbitration shall be borne by the party incurring such expenses.

               10.10.       COUNTERPARTS.

              This Agreement may be executed in one or more counterparts, each
of which shall be deemed an original and all of which together shall be
considered one and the same agreement.

capital stock of the Company owned by them, required to cause the Board to

                    (iii)  In the event there are no Independent Directors

respective power, including in the case of ZGNA and ZBI, the voting of all 
shares of capital stock of the Company owned by them, to appoint three or 
six, as the case may be, additional Independent Directors to the Board.

          SECTION  3.  NOTICE OF MEETINGS; QUORUM.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To Hauser, Inc.:

We have audited the accompanying consolidated balance sheets of Hauser, Inc. (a
Colorado Corporation) and its subsidiaries as of April 30, 1998 and 1997, and
the related consolidated statements of operations, stockholders' equity and cash
flows for the years then ended. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Hauser, Inc. and its
subsidiaries as of April 30, 1998 and 1997, and the results of their operations
and their cash flows for the years then ended in conformity with generally
accepted accounting principles.

                                  HAUSER, INC.
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


1.     BUSINESS ORGANIZATION

       Hauser, Inc. (the "Company"), a Colorado corporation, and its wholly
       owned subsidiaries, Shuster Laboratories, Inc. and Hauser Northwest,
       Inc., is a manufacturer of special products from natural sources, using
       its proprietary technologies in extraction and purification. The Company
       also provides interdisciplinary laboratory testing services, chemical
       engineering services, and contract research and development. The
       Company's existing products are principally marketed to the
       pharmaceutical, dietary supplements and food ingredients industries.

       RISKS AND UNCERTAINTIES - A significant portion of the Company's
       resources are concentrated in the production of bulk paclitaxel. Because
       of a relatively long production cycle for paclitaxel, the Company has
       purchased and committed to purchase significant raw materials (see note
       7), and has committed significant resources to process such raw materials
       in anticipation of delivering paclitaxel to customers in the future. At
       April 30, 1998, the Company had paclitaxel related assets of: $14,321,020
       of both in-process and finished inventory; $3,847,862 as deposits on
       future raw materials; and approximately $4,437,748 net book value of
       related equipment used in the manufacturing process for paclitaxel.

       Under the Waxman-Hatch Act, Bristol-Myers Squibb Company ("Bristol") had
       an exclusive right to sell Taxol-Registered Trademark- in the United
       States, which expired on December 27, 1997. Bristol has also obtained
       certain usage patents which have barred access to the United States
       market. The validity of these patents is currently in litigation. If
       Bristol's usage patents are upheld in the courts, entry into the
       United States market would be significantly delayed, and thus the
       recovery of the Company's investment in paclitaxel related assets would
       also be significantly delayed, or could result in revaluation in the
       amounts recoverable from such assets.

       The Company markets paclitaxel through an exclusive relationship with
       one company in North America and a non-exclusive relationship with one
       company in Europe. The Company's North American partner has approval to
       sell generic paclitaxel in Canada. In Europe, the Company's partner has
       been approved to sell paclitaxel in the Netherlands as an equivalent
       product, not a generic product.

       Further, the Company's customers wishing to enter the market for
       paclitaxel based therapies must obtain proper regulatory approval
       before they can formulate and sell the paclitaxel in final form. Any
       delays in obtaining such approval will similarly delay the Company's
       recovery of its investment in its paclitaxel related assets.

2.     SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

       PRINCIPLES OF CONSOLIDATION - The consolidated financial statements
       include those of the Company and its wholly-owned subsidiaries. All
       significant intercompany transactions have been eliminated in
       consolidation.

       ACQUISITIONS - On July 21, 1995, the Company acquired all of the stock
       of Herbert V. Shuster, Inc. ("Shuster") for approximately $3,959,515 in
       cash and $621,953 in notes plus a performance-based 

                                     - 7 -                          Appendix D
<PAGE>

       earnout for meeting certain milestones over the next five years. The 
       earnout will adjust the cost of the acquisition once any portion of 
       the payment becomes probable. Shuster is a consumer research and 
       development firm and contract laboratory. Subsequent adjustments 
       have increased the purchase price by $209,577.

       The following pro-forma unaudited consolidated results of operations
       for the year ended April 30, 1996, have been prepared assuming the
       Shuster acquisition occurred at the beginning of the fiscal year. These
       pro-forma results have been prepared for comparative purposes only and
       do not purport to be indicative of results of operations which actually
       would have resulted had the acquisition taken effect at the beginning
       of the year.

</TABLE>

       DISCONTINUED OPERATIONS - On October 11, 1996, the Company sold
       substantially all of the net assets of Ironwood for $250,000 in cash,
       notes receivable of $150,000 and certain performance-based earnouts.
       Revenues of Ironwood were $2,670,389 and $8,225,582 in fiscal years
       1997 and 1996, respectively.

       USE OF ESTIMATES - The preparation of financial statements in
       conformity with generally accepted accounting principles requires
       management to make estimates and assumptions that affect the amounts of
       assets and liabilities and disclosure of contingent assets and
       liabilities at the date of these financial statements. Actual results
       could differ from those estimates.
   
       CONCENTRATION OF CREDIT RISK - Financial instruments which potentially
       subject the Company to concentrations of credit risk are accounts
       receivable and investments in debt securities. The Company generally
       grants credit to its customers without collateral. The Company's
       creditors are concentrated in the food processing, nutraceutical and
       pharmaceutical industries. The Company's principal customers (Note 8)
       accounted for 23% and 5% of the Company's accounts receivable as of
       April 30, 1998 and 1997, respectively. The Company's investment in debt
       securities are held entirely in U.S. government treasury securities.
       The Company has no significant financial instruments with off-balance
       sheet risk of accounting loss, such as foreign exchange contracts,
       option contracts or foreign currency hedging arrangements.
    
   
       PRODUCT WARRANTY - Product returns are accepted by the Company only 
       under limited circumstances. Except as described below, the Company has 
       had insignificant product returns and has not historically provided a
       reserve for product returns or remediation.
    
   
       During the fourth quarter of fiscal 1998, the Company took a charge 
       to earnings and reserved $1,500,000 in anticipation of product returns, 
       rework costs, legal and professional fees, and process development 
       costs related to the discovery of a common fungicide, quintozene, in 
       its bulk Panax ginseng. Sales of Panax ginseng accounted for less 
       than 5% of total revenues in fiscal 1998.
    

       ADVERTISING - The Company expenses advertising costs as they are
       incurred.

                                     - 8 -                          Appendix D
<PAGE>

       CASH AND CASH EQUIVALENTS - Cash and cash equivalents include
       investments in highly liquid instruments with original maturities of 90
       days or less.

       INVENTORIES - Raw material, work in process, and finished goods
       inventories, which include costs of materials, direct labor and
       manufacturing overhead, are priced at the lower of average cost or
       market. Writedowns for excess and obsolete inventories are charged to
       expense in the period when conditions giving rise to the writedowns are
       first recognized.

       Non-current inventories represent raw materials and work in process in
       various stages of completion in excess of shipments expected to occur
       in the next fiscal year.

       Inventories as of April 30 consist of the following:

       The Company accounts for equity securities that have a readily
       determinable value and debt securities that are available-for-sale at
       quoted fair values. At April 30, 1997, the Company had an equity
       investment with a cost of $100,000 and a fair value of $502,966.
       Unrealized gains are recorded in stockholders' equity net of the income
       tax effect. This investment was sold during fiscal 1998 for a gain of
       $361,461.

       The Company also invests short-term excess cash in a bond mutual fund
       which is considered to be a cash equivalent. At April 30, 1998 and
       1997, the fund had a quoted market value of $1,120,513 and $4,005,191,
       respectively.

       Other investments consist of 20% or less investments in non-publicly
       traded companies and are accounted for at the lower of cost or market.
       During fiscal 1996, the Company wrote down its investment in a
       development stage company resulting in a loss of $1,000,000. The
       investment was liquidated in the first quarter of fiscal 1997.

                                     - 9 -                          Appendix D

       PROPERTY AND EQUIPMENT - Significant additions and improvements are
       capitalized at cost, while maintenance and repairs which do not improve
       or extend the life of the respective assets are charged to expense as
       incurred.

       Depreciation is recognized on a straight-line basis over the following
       estimated useful lives:

<TABLE>

           Leasehold improvements                        5 -- 10 years
</TABLE>

       Depreciation was $3,738,158, $3,888,336, and $3,356,396 for fiscal
       years 1998, 1997 and 1996, respectively.

       IMPAIRMENT OF LONG-LIVED ASSETS - The Company reviews its long-lived
       assets for impairment whenever events or changes in circumstances
       indicate that the carrying amount of an asset may not be recoverable
       from future undiscounted cash flows. Impairment losses are recorded for
       the difference between the carrying value and fair value of the
       long-lived asset.

       GOODWILL - Goodwill resulting from acquisitions is stated at cost, net
       of accumulated amortization, and is being amortized using the
       straight-line method over an estimated useful life of 10 years.
   
       REVENUE RECOGNITION - Natural product processing revenues are
       recognized when title and risk of ownership passes to the customer
       which generally is upon shipment of processed product. Technical
       services revenues are recognized upon completion of specified contract
       requirements. Unbilled receivables result from costs incurred on
       uncompleted contracts and are included in accounts receivable in the
       accompanying balance sheet. Unbilled accounts receivable at April 30,
       1998 and 1997, were $434,629 and $232,666, respectively. Unanticipated
       losses from contracts are provided for in the period the loss is
       identified. No losses have been accrued as of April 30, 1998 and 1997.
    
   
       Royalty revenues are recognized upon completion of the Company's
       performance obligations with respect to these revenues and coincident
       with the billing requirements defined in the supply contract (generally
       upon sale of the product to an end-user).
    
       RESEARCH AND DEVELOPMENT - Research and development costs are charged
       to expense as incurred.

       STOCK BASED COMPENSATION -The Company accounts for its stock based
       compensation plans for employees under the provisions of Accounting
       Principles Board Opinion No. 25, "Accounting for Stock Issued to
       Employees" ("APB No. 25").

       EARNINGS (LOSS) PER SHARE - During fiscal 1998, the Company adopted
       Statement of Financial Accounting Standards No. 128, "Earnings Per
       Share" ("SFAS 128"), which was required to be adopted on December 15,
       1997. This statement establishes standards for computing and presenting
       basic and diluted earnings per share. Under this statement, basic
       earnings or loss per share is computed by dividing the net earnings or
       loss by the weighted average number of shares of common stock
       outstanding. Diluted earnings or loss per share is determined by
       dividing the net earnings or loss by the sum of (1) the weighted
       average number of common shares outstanding and (2) if not
       anti-dilutive, the effect of outstanding warrants and stock options
       determined utilizing the 

                                     - 10 -                         Appendix D
<PAGE>

       treasury stock method. The adoption of SFAS 128 had no effect on 
       previously reported earnings (loss) per share.

       In fiscal 1998, 1997 and 1996, stock options and warrants totaling
       709,256, 548,362, and 443,687 respectively were excluded from the
       calculation of diluted earnings (loss) per share since the result would
       have been anti-dilutive.

       FAIR VALUE OF FINANCIAL INSTRUMENTS - Due to the short-term nature of
       the Company's debt, accounts receivable and other financial
       instruments, the fair value of such financial instruments approximates
       their carrying amount.

       RECLASSIFICATIONS - Certain prior year amounts have been reclassified
       to conform to the current year presentation.

       RECENTLY ISSUED ACCOUNTING STANDARDS - In June 1997, the Financial
       Accounting Standards Board ("FASB") issued Statement of Financial
       Accounting Standards No. 130, "Reporting Comprehensive Income," ("SFAS
       130"). SFAS 130 establishes standards for reporting and displaying
       comprehensive income and its components in a financial statement that
       is displayed with the same prominence as other financial statements.
       SFAS 130 is effective for fiscal years beginning after December 15,
       1997. Comprehensive (loss) would have been approximately ($3,380,000),
       ($6,750,000) and ($7,270,000) for the years ended April 30, 1998, 1997,
       and 1996, respectively.
   
       In June 1997, the FASB issued Statement of Financial Accounting
       Standards No. 131, "Disclosures about Segments of an Enterprise and
       Related Information," ("SFAS 131"). SFAS 131 requires that public
       companies report information about their operating segments based on
       the financial information used by the chief operating decision maker in
       their annual financial statements and requires those companies to
       report selected information in their interim statements. SFAS 131 is
       effective for fiscal years beginning after December 15, 1997.
       Management has not determined what segments, if any, will be reported
       in connection with the adoption of SFAS 131.
    
       In June 1998, the FASB issued Statement of Financial Accounting
       Standards No. 133, "Accounting for Derivative Instruments and Hedging
       Activities," ("SFAS 133"). SFAS 133 establishes accounting and
       reporting standards for derivative instruments, including certain
       derivative instruments embedded in other contracts and for hedging
       activities. It requires that an entity recognizes all derivatives as
       either assets or liabilities in the statement of financial position and
       measures those instruments at fair value. SFAS 133 is effective for
       fiscal quarters and fiscal years beginning after June 15, 1999.
       Management believes that the adoption of SFAS 133 will not have a
       significant impact on the Company's financial condition and results of
       operations.

       At April 30, 1998 and 1997, property and equipment includes items under
       capital leases with book values of $1,032,293 and $138,396,
       respectively, and accumulated depreciation of $247,570 and $85,208,
       respectively.

       LINES OF CREDIT - The Company has an $8,850,000 bank line of credit
       which allows the Company to obtain advances or letters of credit
       against a borrowing base of eligible accounts receivable, inventory and
       fixed assets. As of April 30, 1998, $1,500,000 had been borrowed
       against the line. The line of credit has an annual fee of 0.50% of the
       unused portion of the line and interest is payable monthly at the
       bank's prime rate plus 0.75% (9.25% at April 30, 1998). The line of
       credit expires June 30, 2000 and is secured by all assets of the
       Company, with the exception of intangibles.

       Under the terms of the lending agreement, the Company cannot pay any
       dividends without the consent of the bank and is required to maintain
       certain financial ratios and minimum working capital and equity
       amounts. As of April 30, 1998, the Company was not in compliance with a
       financial covenant for the line of credit which required the Company to
       report profitability in the fourth quarter of fiscal 1998. The Company
       has obtained a waiver from the bank for this covenant as of April 30,
       1998.

       Restricted cash is equal to interest due over one year based on the
       amount borrowed and is required to be maintained on deposit at a
       financial institution as security for the Company's line of credit.
       Cash on deposit at April 30, 1998 was $139,346.

       In addition, the Company has a lease line of credit for $564,000, of
       which $346,083 was available for use at April 30, 1998. The interest
       rate on the lease line is the bank's cost of funds plus 2.5% (8.54% at
       April 30, 1998) and the line expires on April 8, 2000.

4.     STOCKHOLDERS' EQUITY

       NON-QUALIFIED STOCK OPTIONS - The Company's 1987 Stock Option Plan (the
       "1987 Plan") authorizes the granting of non-qualified stock options for
       up to 1,218,720 shares of the Company's 

                                     - 12 -                         Appendix D

         common stock by directors, employees, and consultants. As of April 
         30, 1998, there were 813,237 shares of common stock committed under 
         this plan. Exercise terms, ranging from one to ten years for options 
         granted under the 1987 Plan, are determined by the Board of 
         Directors at the time of grant. A summary of the status of the 
         Company's 1987 Non-Qualified Stock Option Plan follows.

         INCENTIVE STOCK OPTIONS -The Company's 1992 Stock Option Plan ("1992 
         Plan") authorizes the granting of 700,000 shares of common stock to 
         employees at fair market value on the date of grant. As of April 30, 
         1998, there were 439,162 shares committed under this plan. Exercise 
         terms, ranging from one month to ten years for options granted under 
         the 1992 Plan, are determined by the Board of Directors at the time 
         of grant. A summary of the status of the Company's 1992 Plan follows:

         WARRANTS - The Company has issued to consultants and stockholders 
         warrants for the purchase of common stock. Exercise terms were 
         determined by the Board of Directors at the time of grant. During 
         fiscal 1996 and 1998, no warrants were issued. During fiscal 1997, 
         48,477 warrants were issued at a weighted average exercise price of 
         $6.03 and a grant date fair value of $147,306. During fiscal 1996, 
         1,334 warrants were exercised at $1.50. At April 30, 1998, 48,477 
         warrants remained outstanding at exercise prices ranging from $5.67 
         to $6.22 per warrant.

         VALUATION - The weighted average fair value of each option grant or 
         warrant has been estimated as of the date of grant using the 
         Black-Scholes option-pricing model using the following assumptions.

Expected life (in years)               5.6            5.0            5.0
</TABLE>

         Using these assumptions, the fair value of the stock options granted 
         in fiscal years 1998, 1997, and 1996 was estimated to be 
         approximately $1,107,242, $480,271, and $632,440, respectively. Had 
         compensation cost been recorded based on the fair value of the 
         option or warrant grants, the Company's pro-forma net loss and net 
         loss per share would have been as follows for the years ended April 
         30:

         The Company has approximately $4.3 million of federal and $24.4 
         million of state net operating loss carry forwards that expire in 
         varying amounts through the year 2013 and approximately $641,000 of 
         capital loss carry forwards expiring in 2001. The Company also has 
         available income tax credits of $510,265, expiring on varying dates 
         through 2013 and alternative minimum tax credits of $1,484,151, 
         which do not expire. Realization is dependent on generating 
         sufficient taxable income or realization of future taxable temporary 
         differences prior to expiration of the carryforwards. Although 
         realization is not assured, management believes it is more likely 
         than not that the recorded net deferred tax assets will be realized.
   
         During fiscal 1998, the Company increased its valuation allowance by 
         approximately $418,000 due mainly to the one-time product warranty 
         charge. In assessing the amount of its net deferred tax assets 
         considered realizable, management has considered the following 
         factors: (1) taxable income projected within the next twenty-four 
         months; (2) the expiration dates of its net operating loss and tax 
         credit carryovers; (3) tax planning strategies which would allow 
         Hauser to generate significant taxable income from existing assets 
         (including possible sale-leaseback scenarios for its land, property 
         and equipment held fee simple); and (4) alternative strategies for 
         its paclitaxel business. The amount of the deferred tax asset 
         considered realizable could be reduced in the near term if estimates 
         of future taxable income do not materialize.
    
         The Company recognized a reduction of income taxes payable of 
         $18,348, $48,286, and $29,700 as a result of the exercise of stock 
         options by employees and others during the years ended April 30, 
         1998, 1997, and 1996, respectively. The benefit was credited 
         directly to additional paid-in capital.

6.   EMPLOYEE BENEFIT PLAN

     The Company sponsors a 401(k) plan (the "Plan") for all employees who
     have completed one year of service. Participants may contribute up to
     15% of their annual compensation subject to dollar limitations of
     Section 402(g) of the Internal Revenue Code. At the discretion of the
     Board of Directors, the Company matches, with a cash contribution, 20%
     of the first 6% of the participant's contribution and the remaining 80%
     of the participant's contribution with common stock. The Company has
     reserved 200,000 shares of common stock for issuance under the Plan.
     The Company's matching portion vests 20% per year over 5 years. The
     Plan is subject to the provisions of the Employee Retirement Income
     Security Act of 1974. The Company did not make a contribution to the
     Plan for the years ended April 30, 1998, 1997 and 1996.

7.   COMMITMENTS AND CONTINGENCIES

     PURCHASE COMMITMENTS - The Company has entered into growing contracts 
     with numerous nurseries for the future purchase of natural raw materials 
     to be used in the Company's manufacturing processes. In some cases, the 
     Company may, at its option, decide at any time to discontinue the 
     payments on these contracts for nutraceuticals and pharmaceutical 
     products. If such decisions are made in the future, the Company would 
     not be able to recover deposits made on the growing contracts, but would 
     reduce the future commitment on these contracts to approximately $5.0 
     million. As of April 30, 1998, the Company has $3,847,862 in deposits 
     for such contracts. The future commitments for purchases under these 
     contracts at April 30, 1998 are as follows:

9.   SUBSEQUENT EVENT

     On December 9, 1998, the Company entered into an agreement to merge
     with three subsidiaries of privately held Zuellig Group N.A. Inc.
     ("ZGNA"). The agreement calls for the Company to

      exchange approximately 10.1 million shares of common stock for 
      the acquired subsidiaries, subject to adjustment as described in 
      the Escrow Agreement. The acquired subsidiaries are already 
      aligned with the Company's Natural Ingredients and Technical 
      Services business unit, but are unrelated to the Company's 
      Pharmaceutical business unit. As part of the merger agreement, 
      the Company agreed to exit the business of producing bulk
      paclitaxel. The Company will incur a one-time charge of approximately
      $25-$30 million in its third fiscal quarter ended January 31,1999. This
      charge includes non-cash charges of approximately $9.5-$11.0 million to
      write down paclitaxel and related inventory to its estimated net
      realizable value of approximately $9.8 million to be disposed in the
      last half of fiscal 1999, a charge of a approximately $4.5-$5.5 million
      to write off the Company's deposits on growing contracts for Yew trees,
      a charge of approximately $5.0-$6.0 million to write off paclitaxel
      processing equipment and a charge of approximately $1.0-$1.5 million to
      write off patents, goodwill and other assets. The charge will also
      include the accrual of approximately $5.0-$6.0 million for the
      estimated additional costs of exiting the paclitaxel business. All
      inventory related charges will be included in cost of revenues on the
      Company's statement of operations, and all non-inventory charges will
      be included in operating expenses.

HAUSER, INC.

   

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS AS OF JANUARY 31, 1999
AND APRIL 30, 1998 AND FOR THE THREE AND NINE MONTH PERIODS ENDED
JANUARY 31, 1999 AND 1998 (UNAUDITED)

    
   
1.       BASIS OF PRESENTATION
    
   

In the opinion of management, the accompanying unaudited financial statements 
contain all adjustments (consisting only of normal recurring adjustments) 
necessary to present fairly the Company's financial position as of January 
31, 1999, and results of its operations and cash flows for the periods ended 
January 31, 1999 and 1998. The year-end balance sheet data was derived from 
audited financial statements, but does not include all disclosures required 
by generally accepted accounting principles. Certain fiscal 1998 amounts have 
been reclassified to conform to the fiscal 1999 presentation.

    

USE OF ESTIMATES - The preparation of financial statements in conformity with 
generally accepted accounting principles requires management to make 
estimates and assumptions that affect the amounts of assets and liabilities 
and disclosure of contingent assets and liabilities at the date of these 
financial statements. Actual results could differ from those estimates.

   
2.       INVENTORIES
    

Raw material, work in process, and finished goods inventories, which include 
costs of materials, direct labor and manufacturing overhead, are priced at 
the lower of average cost or market. Write-downs for excess and obsolete 
inventories are charged to expense in the period when conditions giving rise 
to the write-downs are first recognized. The Company purchases raw material 
inventory during harvest seasons, generally in the spring and fall. These 
purchases may take place well in advance of scheduled production of finished 
product.

Non-current inventories represent raw materials, work in process, and 
finished goods in various stages of completion in excess of shipments 
expected to occur in the next fiscal year.

   

In connection with the Merger (See Note 7), Hauser executed an inventory 
purchase agreement with Zuellig which is intended to provide interim 
financing for Hauser. Included in Deposits as of January 31, 1999, is $3 
million received pursuant to this agreement. The purchase price for the 
inventory is the lower of cost or market. At any time, Hauser may require 
Zuellig to resell to Hauser all or any portion of the inventory purchased by 
Zuellig at the same price at which Zuellig purchased the inventory and 
require Zuellig to purchase substantially similar raw material and finished 
product having a value substantially equivalent to the repurchased inventory. 
Hauser will recognize revenue from the transaction upon the sale of the 
inventory to an unrelated party.

         BANK LINE OF CREDIT - The Company has a $7,000,000 bank line of 
credit at the bank's prime interest rate plus 0.75% which matures on May 15, 
1999. The Company expects to pay the balance of this line of credit from the 
new credit facility with Wells Fargo Bank, N.A. as a result of the 
anticipated merger with Zuellig Group N.A., Inc. ("Zuellig"). As of January 
31, 1999, the Company was not in compliance with the financial covenants for 
the line of credit. The Company has obtained a waiver from the bank through 
January 31, 1999.

    
   
4.       EARNINGS (LOSS) PER SHARE
    
   

         The Company calculates basic earnings (loss) per share by dividing 
the net earnings or loss by the weighted average number of shares of common 
stock outstanding. Diluted earnings (loss) per share is determined by 
dividing the net earnings or loss by the sum of (1) the weighted average 
number of common shares outstanding and (2) if not antidilutive, the effect 
of outstanding warrants and stock options determined utilizing the treasury 
stock method. For the three months ended January 31, 1999, and 1998, 471 and 
569,316 options were excluded from the calculation of diluted

                                    - 6 -                            Appendix E

<PAGE>

earnings (loss) per share since the result would have been antidilutive. For 
the nine months ended January 31, 1999, and 1998, 6,010 and 592,991 options 
were excluded from the calculation of diluted earnings (loss) per share since 
the result would have been antidilutive.

    
   
5.       PRODUCT WARRANTY
    
   

         During the fourth quarter of fiscal 1998, the Company took a charge 
to earnings and reserved $1,500,000 in anticipation of product returns, 
rework costs, legal and professional fees, and process development costs 
related to the discovery of a contaminant in its bulk Panax ginseng. In the 
nine months ended January 31, 1999, the Company charged $1,500,000 against 
the reserve for expenses associated with this issue.

    
   
6.       RECENTLY ISSUED ACCOUNTING STANDARDS
    
   

         In June 1997, the Financial Accounting Standards Board ("FASB") 
issued Statement of Financial Accounting Standards No. 130, "Reporting 
Comprehensive Income," ("SFAS 130"). SFAS 130 establishes standards for 
reporting and displaying comprehensive income and its components in a 
financial statement that is displayed with the same prominence as other 
financial statements. SFAS 130 is effective for fiscal years beginning after 
December 15, 1997. Comprehensive income (loss) would have been approximately 
$(26,259,782) and ($647,363) for the quarters ended January 31, 1999, and 
1998, respectively, and ($27,252,695) and ($1,648,976) for the nine months 
ended January 31, 1999, and 1998, respectively.

    
   

         In June 1997, the FASB issued Statement of Financial Accounting 
Standards No. 131, "Disclosures about Segments of an Enterprise and Related 
Information," ("SFAS 131"). SFAS 131 requires that public companies report 
information about their operating segments based on the financial information 
used by the chief operating decision maker in their annual financial 
statements and requires those companies to report selected information in 
their interim statements. SFAS 131 is effective for fiscal years beginning 
after December 15, 1997. Management has not determined what segments, if any, 
will be reported in connection with the adoption of SFAS 131.

    
   

         In June 1998, the FASB issued Statement of Financial Accounting 
Standards No. 133, "Accounting for Derivative Instruments and Hedging 
Activities," ("SFAS 133"). SFAS 133 establishes accounting and reporting 
standards for derivative instruments, including certain derivative 
instruments embedded in other contracts and for hedging activities. It 
requires that an entity recognizes all derivatives as either assets or 
liabilities in the statement of financial position and measures those 
instruments at fair value. SFAS 133 is effective for fiscal quarters and 
fiscal years beginning after June 15, 1999. Management believes that the 
adoption of SFAS 133 will not have a significant impact on the Company's 
financial condition and results of operations.

    
   
7.       MERGER
    
   

         On December 9, 1998, the Company announced that it had entered into 
an agreement to merge with three subsidiaries (the "Contributed 
Subsidiaries") of Zuellig. The agreement calls for the Company to exchange 
approximately 10.05 million common shares of stock for the Contributed 
Subsidiaries. The Contributed Subsidiaries are already aligned with the 
Company's Natural

                                    - 7 -                            Appendix E

<PAGE>

Ingredients and Technical Services business units, but are unrelated to the 
Company's Pharmaceuticals business unit. Therefore, as a direct result of the 
decision to acquire these subsidiaries, the Company has decided to 
discontinue its paclitaxel supply activities. The Company's original intent 
was to resume production of paclitaxel once current legal and regulatory 
issues were resolved.

    
   

         In the quarter ended January 31, 1999, the Company incurred a 
one-time charge to earnings of $25.6 million. The charge to cost of sales was 
comprised of a reduction of bulk paclitaxel inventory ($10.2 million) to its 
estimated net realizable value, a write-off of advanced payments made for the 
purchase of cultivated yew trees ($4.5 million) and the estimated costs of 
terminating cultivar nursery contracts ($5.0 million). The charge to 
operating expenses includes the write-off of paclitaxel related equipment 
($4.7 million) and miscellaneous other related assets consisting primarily of 
intangibles ($1.2 million). The net realizable inventory was determined based 
upon a contract signed on February 11, 1999, to sell bulk paclitaxel over the 
next nine months for a sales value of $9.5 million. The cost to terminate the 
cultivar nursery contracts was based on the current contractual terms. The 
specialized paclitaxel equipment and related intangibles have no alternative 
use and were written down to zero. The Company does not anticipate any 
significant reduction in workforce as a result of the decision to cease 
production of paclitaxel. The Company should complete its exit of the 
paclitaxel business within the next twelve months.

HAUSER, INC.

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

OVERVIEW
   
     The Company has focused its efforts during the last four years through 
growth in the natural ingredients markets, and in expanding its strength 
providing technical services to clients. Sales of NaturEnhance-TM- natural 
ingredients, which include nutraceuticals, flavors and food ingredients, 
increased 117% in the year ended April 30, 1998, compared the prior fiscal 
year, and this growth has continued into fiscal year 1999. Revenues from 
technical services increased almost 61% in the year ended April 30, 1998, 
compared to the prior fiscal year. Technical Services revenues in the nine 
months ended January 31, 1999, increased 27% over the same period in fiscal 
year 1998. Offsetting these improvements has been a decline in pharmaceutical 
revenues.
    
   
     On December 9, 1998, the Company announced it had entered into an 
agreement to merge with three subsidiaries of privately-held Zuellig Group N. 
A., Inc., ("ZGNA"). The transaction is currently valued at approximately $49 
million. The Company will acquire Zuellig Botanical Extracts, Inc., Wilcox 
Drug Company, Inc., and ZetaPharm, Inc., thereby creating a leading U.S. 
supplier of herbal extracts, botanical raw materials and related products to 
the fast-growing nutritional industry. Sales for the three acquired companies 
for the four quarters ended September 30, 1998, exceeded $100 million.
    
   
     The agreement calls for the Company to exchange approximately 10.05 
million of the Company's common shares for the common stock of the acquired 
subsidiaries. Upon closing, the Company's shareholders will own 51.0% of the 
combined company, while ZGNA will own 49.0%. The number of shares to be 
issued to ZGNA are subject to downward adjustment under certain 
circumstances. The Company also will assume approximately $20.6 million of 
the Contributed Subsidiaries' bank debt. Wells Fargo Bank, N.A. will provide 
a $35.0 million line of credit and a $10.0 million fixed asset line in 
support of the merged companies. The agreement is subject to approval by the 
Company's shareholders and customary closing conditions. Management expects 
the transaction to close during the Company's fiscal 1999 fourth quarter and, 
aside from transaction related charges, to be accretive to earnings in fiscal 
year 2000.
    
   
     As a result of the merger, the Company has decided to discontinue its 
paclitaxel activities. In the quarter ended January 31, 1999, the Company 
incurred a one-time charge to earnings of $25.6 million. The charge to cost 
of sales was comprised of a reduction of bulk paclitaxel inventory ($10.2 
million) to its estimated net realizable value, a write-off of advanced 
payments made for the purchase of cultivated yew trees ($4.5 million) and the 
estimated costs of terminating cultivar nursery contracts ($5.0 million). The 
charge to operating expenses includes the write-off of paclitaxel related 
equipment ($4.7 million) and miscellaneous other related assets consisting 
primarily of intangibles ($1.2 million). The net realizable inventory was 
determined based upon a contract signed on February 11, 1999 to sell 
substantially all of its paclitaxel inventory over the next six to nine 
months for a sales value of $9.5 million. The cost to terminate the cultivar 
nursery contracts was based on the current contractual terms. The

                                   - 1 -                            Appendix F

specialized paclitaxel equipment and related intangibles have no alternative 
use and were written down to zero. The Company does not anticipate any 
significant reduction in workforce as a result of the decision to cease 
production of paclitaxel. The Company should complete its exit of the 
paclitaxel business within the next twelve months.
    

     On May 21, 1998, the Company announced the discovery of small amounts of 
a common fungicide called quintozene in its bulk Panax ginseng that had been 
shipped to customers. The Company had used Environmental Protection Agency 
guidelines to screen for herbicides and pesticides, but this particular 
fungicide was not included in the general guidelines. The Company immediately 
stopped all Panax ginseng processing and shipments, pending further testing 
and discussions with regulatory authorities. Based upon test results and 
analytical reviews of the substance, the Company believes that the levels of 
quintozene present in the bulk extract are well below any reasonable risk 
levels.
   
     However, management expected that the existence of this fungicide in the 
Panax ginseng would create additional cost to the Company. As such, a charge 
to earnings of $1,500,000 was taken in the fourth quarter of fiscal 1998 in 
anticipation of product returns, re-work costs, development work required to 
provide methodology to remove the substance from the bulk extracts, and legal 
and professional fees. Sales of Panax ginseng generated less than 5% of total 
revenues in fiscal 1998, and management believes that the temporary hold on 
shipments of this product will not have a material impact on the future 
operations of the Company. As of January 31, 1999, all costs associated with 
this reserve have been incurred and were adequate to cover substantially all 
cost related to this situation.
    
     On September 13, 1996, the Company adopted plans to sell substantially 
all of the net assets of its secondary forest products subsidiary, Hauser 
Northwest, Inc., d/b/a Ironwood Evergreens (Ironwood). On October 11, 1996, 
this sale was completed. Revenues for Ironwood were $2,670,389 and $8,225,582 
in the fiscal years ended April 30, 1997, and 1996, respectively.

     The following is a discussion of the Company's activities in its 
continuing operations.

NATURAL INGREDIENTS

     NUTRACEUTICALS - The term nutraceuticals is used to identify the broad 
range of natural, healthful products that are used to supplement the diet by 
increasing the total dietary intake of important nutrients. The United States 
market for herbal and botanical supplements is estimated to be $2.3 billion, 
and is growing at over 20% per year, according to industry sources. The 
Company's products include liquid and dry herbal extracts of Echinacea, 
Valerian, St. John's wort, Siberian ginseng, Panax ginseng, Ginger, 
Goldenseal, Kava Kava, Black Cohash, Saw Palmetto and Rosemary 
(RoseOx-Registered Trademark-). Management believes that the Company's 
expertise in the production of special products from natural sources and its 
extensive regulatory experience position it well in this market area.
   
      On December 3, 1997, the Company announced that the value of signed 
agreements with PharmaPrint, Inc. ("PharmaPrint") was expected to be $20 
million over the next three years. The Company continues to manufacture 
botanical products and provides research and development

                                   - 2 -                            Appendix F

<PAGE>


services to PharmaPrint to support its herbal-based pharmaceuticals. Sales of 
products and services to PharmaPrint in the year ended April 30, 1998, were 
14.9% of total revenues and were 11% of total revenues in the nine months 
ended January 31, 1999. Management expects the level of sales to PharmaPrint 
to decline during fiscal 1999 because of fewer sales of herbal products and 
technical services as well as growth in sales to other customers.
    
   
     On November 14, 1996, the Company signed a three-year contract to supply 
RoseOx-Registered Trademark-, an antioxidant nutraceutical product, to D&F 
Industries ("D&F"), a manufacturer of vitamin and food supplement products. 
Under that agreement, D&F had exclusive marketing rights to the Company's 
antioxidant nutraceutical products, RoseOx-Registered Trademark- and 
RoseOx660-Registered Trademark-, in the multi-level dietary supplement and 
cosmetic markets. The Company began shipping product under this contract 
during the third quarter of fiscal year 1997, and delivered contractual 
quantities through the second quarter of fiscal 1998. Sales to D&F comprised 
9% of total revenues in the nine-month period ended January 31, 1998.
    
     On November 6, 1997, the Company announced it had mutually agreed with 
D&F, to cancel the exclusivity agreement between the companies. This change 
in exclusivity allows the Company to market RoseOx-Registered Trademark- 
products directly through its sales force. The Company is currently working 
on a revised sales plan to market the RoseOx-Registered Trademark- product. 
Sales volume of this product are not yet at previous levels and no assurance 
can be given as to when sales volume will return to previous levels.
   
     NATURAL FOOD INGREDIENTS - The Company manufactures, markets and sells 
natural food ingredients which include natural flavor extracts and 
antioxidants. The extracts are marketed under the Company's brand name 
NATURENHANCE-Registered Trademark- Food Ingredients. Competition for products 
in the flavor extract market is based on flavor quality and concentration, 
availability, customer service, and price. Some of these factors are beyond 
the direct control of the Company.
    
   
     The Company also sells products which perform a function in foods, such 
as preservatives, stabilizers, colorants, antioxidants, and nutritional 
additives. The Company's objective is to build a quality line of products 
generating revenues and profits in the development, manufacture and sale of 
natural food ingredients.
    
   
     Minimal revenue from natural food ingredients products was recognized in 
fiscal year 1998, but shipments have increased because of expanded marketing 
efforts generating interest from potential customers. The Company announced 
on November 3, 1997, its signing of a three year agreement with RFI 
Ingredients ("RFI"), whereby RFI will serve as exclusive distributors for the 
Company's NATURENHANCE-TM- product lines to the foods and beverages 
industries. To improve the success of these products, the Company has reduced 
the number of products offered to allow for improved marketing focus and 
technical support of the remaining products. However, management is unable to 
predict the timing and amount of future revenues from natural food 
ingredients products.

TECHNICAL SERVICES
   
     The Technical Services business unit, comprised of Hauser Laboratories 
and Shuster Laboratories, Inc., (the Company's wholly-owned subsidiary), 
operates as a single entity in the research and development, formulation, 
analysis and project delivery to fee-for-service clients. During the year 
ended April 30, 1998, Technical Services revenues increased almost 61% over 
the previous year, and in the nine months ended January 31, 1999, these 
revenues increased 27% over the nine month period ended January 31, 1998. 
These increases reflect the Company's concentrated efforts to increase the 
number of projects related to custom synthesis and natural products isolation 
in the pharmaceuticals industry. Also, Shuster's Technically Advanced Quality 
Assurance ("TAQA-TM-") and Foods 2000 initiatives have contributed additional 
revenues.
    
     The Company announced on November 6, 1997, a collaborative agreement 
with The National Institute on Drug Abuse ("NIDA"), for custom synthesis of 
drug compounds that are under development as potential treatment agents for 
various drug addictions. Under the agreement, the Company will receive $2.3 
million over a three-year period.

     Management believes that demand for technical services will continue to 
increase and expects this business unit to grow. On-going marketing efforts 
in the Company's Technical Services business unit will be centered on 
projects that provide opportunity to employ the collective capabilities of 
the Hauser Laboratories' and Shuster Laboratories' team.

PHARMACEUTICALS

     The Company has been a supplier of bulk paclitaxel for approximately the 
last seven years. The Company's customers wishing to enter the market for 
paclitaxel-based therapies must obtain proper regulatory approval before they 
can formulate and sell paclitaxel in final form. The U.S. market, which 
comprises approximately 65% of the world market, has been severely restricted 
because of administration patents held by Bristol-Myers Squibb, Company 
("Bristol"). Additionally, the Company learned in November 1998, that its 
European customer, Yew Tree Pharmaceuticals ("Yew Tree"), had concluded an 
agreement with Bristol whereby Yew Tree will cease selling its paclitaxel 
product by the end of December 1998.
   
     The pending merger with ZGNA will focus corporate resources on extract 
products for the dietary supplement market and Technical Services. As a 
result, management will discontinue its paclitaxel supply activities. In the 
quarter ended January 31, 1999, the Company incurred a one-time charge to 
earnings of $25.6 million. The charge to cost of sales was comprised of a 
reduction of bulk paclitaxel inventory ($10.2 million) to its estimated net 
realizable value, a write-off of advanced payments made for the purchase of 
cultivated yew trees ($4.5 million) and the estimated costs of terminating 
cultivar nursery contracts ($5.0 million). The charge to operating expenses 
includes the write-off of paclitaxel related equipment ($4.7 million) and 
miscellaneous other related assets consisting primarily of intangibles ($1.2 
million). The net realizable inventory was determined based upon a contract 
signed on February 11, 1999 to sell bulk paclitaxel over the next nine months 
for a sales value of $9.5 million. The cost to terminate the cultivar nursery 
contracts was based on the current contractual terms. The specialized 
paclitaxel equipment and related intangibles have no alternative use and were 
written down to

zero. The Company does not anticipate any significant reduction in workforce 
as a result of the decision to cease production of paclitaxel. The Company 
should complete its exit of the paclitaxel business within the next twelve 
months.
    

DISCONTINUED OPERATIONS

     On October 11, 1996, the Company sold substantially all of the net 
assets of its secondary forest products subsidiary, Hauser Northwest, Inc., 
d/b/a Ironwood Evergreens ("Ironwood"). Revenues for Ironwood were $2,670,389 
and $8,225,582 in the years ended April 30, 1997 and 1996, respectively. The 
results for fiscal 1997 include a non-recurring charge for the divestiture of 
Ironwood.

     The Company received cash of $250,000, a promissory note of $150,000 and 
a basic earnout of no more than $550,000. The earnout is based upon 75% of 
the buyer's net cash flow, if any, derived from the business for the 
four-year period ending December 31, 2000. An additional earnout of 5% of the 
excess (if any) of net cash flow over the projected net cash flow in the 
buyer's five-year plan is available to the Company. The maximum additional 
earnout is $400,000. The Company has not earned any amounts available under 
either the basic or additional earnout.

</TABLE>

Total revenues in fiscal 1998 increased 27% to $32,037,528 from $25,225,766 
in fiscal 1997. This increase was the result of increases in natural 
ingredients product sales and increases in technical service revenues, offset 
by a decline in the sales of bulk paclitaxel to pharmaceutical customers. 
Revenues increased almost 45% in fiscal 1997 as compared to fiscal 1996 due 
to increased revenues from the sales of pharmaceutical and nutraceutical 
products.

Natural ingredients:
Natural ingredients product revenues increased almost 117% in fiscal 1998 to 
$13,674,835 from $6,308,055 in fiscal 1997. The increase is primarily 
attributable to success in selling nutraceutical products as revenues were 
$12,531,190 in fiscal 1998, an increase of $7,997,840 from revenues of 
$4,533,350 in fiscal 1997. Revenues from the sales of natural flavor extracts 
in fiscal 1998 were $960,267, a 44% decrease from revenues of $1,700,945 in 
fiscal 1997. This decrease was primarily due to low sales activities until 
November, 1997 at which time a distributor was hired to market the products. 
In addition, the Company sold food ingredients products of $183,378 in fiscal 
1998 compared to revenues of $73,760 in fiscal 1997.

Natural ingredients product revenues increased almost 139% in fiscal 1997 to 
$6,308,055 from $2,642,481 in fiscal 1996. The increase is primarily 
attributable to success in selling nutraceutical products as revenues were 
$4,533,350 in fiscal 1997, an increase of $3,730,665 from revenues of 
$802,685 in fiscal 1996. Revenues from the sales of natural flavor extracts 
in fiscal 1997 were $1,700,945, a 6% decrease from revenues of $1,815,796 in 
fiscal 1996. This small decrease was primarily due to the shift in marketing 
activities from the Company's reliance on Tastemaker in fiscal 1996 to its 
own internal sales efforts. In addition, the Company sold food ingredients 
products of $73,760 in fiscal 1997 compared to revenues of $24,000 in fiscal 
1996.

Technical Services:
Technical services revenues were $14,507,424 in fiscal 1998 compared to 
$9,034,787 in fiscal 1997, an increase of almost 61%. This increase was due 
primarily to the Company's concentrated efforts to increase the number of 
projects related to custom synthesis and natural products isolation in the 
pharmaceuticals industry. Additionally, research and development services 
from both Hauser and Shuster laboratories were sold to PharmaPrint during the 
year as part of the expanded relationship mentioned earlier.

Technical services revenues were $9,034,787 in fiscal 1997 compared to 
$9,315,672 in fiscal 1996, a decrease of about 3%. This decrease was due 
primarily to the loss of a major customer of Shuster in fiscal 1997.

Pharmaceuticals:
   

Revenues from pharmaceuticals products in fiscal 1998 decreased 61% compared 
to fiscal 1997. This was due to decreased sales of bulk paclitaxel because of 
regulatory issues and on-going litigation which have created uncertainty in 
the market. Pharmaceutical sales are largely dependent upon the Company's 
strategic customers, and legal and regulatory issues that are out of the 
Company's control that create unpredictability quarter-to-quarter. Total 
revenues from bulk paclitaxel and taxanes were $3,855,269 in fiscal 1998 
compared to revenues of $9,142,913 in fiscal 1997.

Revenues from pharmaceutical products in fiscal 1997 increased more than 80% 
compared to fiscal 1996. This was due to increased sales of paclitaxel to two 
customers. The Company signed an agreement with Yew Tree in November, 1996 to 
supply bulk paclitaxel over a three-year period and made a significant 
shipment to this customer during the third quarter ended January 31, 1997. In 
addition, the Company shipped bulk paclitaxel to another customer during 
fiscal 1997 for use in its development efforts. The Company does not have a 
long-term supply agreement with this customer. Total revenues from bulk 
paclitaxel and taxanes were $9,142,913 in fiscal 1997, an approximately 101% 
increase over revenues of $4,547,819 in fiscal 1996 from the same products.

The Company recognized revenues of $740,011 for the shipment of sanguinaria 
extract to Colgate during fiscal 1997 as compared to revenues of $933,460 in 
fiscal 1996. No revenues from sanguinaria extract were recognized in fiscal 
1998. Fiscal 1997 shipments of sanguinaria extract completed the requirements 
of the Company's contractual obligations with Colgate, and the Company does 
not expect additional orders in the foreseeable future. The expiration of 
this contract did not and will not have a material impact on the operations 
of the Company.

GROSS PROFIT (LOSS). Gross margin for the natural products industry segment 
in fiscal 1998 was 13.9% of total revenues as compared to 16.5% in fiscal 
1997 and negative 40.9% in fiscal 1996. The decline in fiscal 1998 is 
primarily due to lower sales of paclitaxel offset by significantly higher 
sales of natural ingredients products. The improvement in fiscal 1997 was the 
result of two large sales of paclitaxel. The Company recognized improved 
gross margins from the sales of nutraceuticals products in fiscal 1998 due to 
changes in pricing and increased manufacturing efficiencies. However, margins 
from these sales vary because of product mix. In addition, the Company is 
still incurring high overhead costs in relation to its current sales levels, 
the result of excess plant capacity.

Gross margin for technical services increased in fiscal 1998 to 30% of 
revenue as compared to 14% in fiscal 1997 and 24% of revenues in fiscal 1996. 
The increase in fiscal 1998 was the result of more projects related to drug 
development and natural ingredients formulations that generated higher 
margins. The decline in fiscal 1997 was the result of the mix of services 
provided, including more analytical and testing services which generate lower 
margins.

OPERATING EXPENSES. Research and development expenses were $2,229,843 in 
fiscal 1998 compared to $2,240,992 in fiscal 1997 and $2,157,708 in fiscal 
1996. While research and development expenses have remained approximately 
flat, the Company intends to actively continue research and development 
efforts and expenses in this area could increase over the next year to 
support the growing needs of the Company.

Sales and marketing expenses in fiscal years ending April 30, 1998, 1997, and 
1996 were $2,390,602, $1,619,937, and $1,167,447, respectively. The increase 
represents the Company's accelerated efforts to market new products, 
particularly in the areas of nutraceuticals and natural food ingredients. 
Fiscal 1998 and 1997 sales expenses include payments of commissions to 
internal salespeople and external distributors, and these costs have 
increased as sales have increased.

                                   - 8 -                            Appendix F

General and administrative expenses were $5,369,527 in fiscal 1998, a 12% 
decrease from $6,095,770 in fiscal 1997. Fiscal 1997 general and 
administrative expenses declined 2% as compared to fiscal 1996. The decrease 
in fiscal 1998 was the result of lower insurance, legal and consulting fees. 
In addition, the fiscal 1997 expense includes a charge of $345,000 for the 
disposition of certain production facility assets. These decreases are the 
result of management's continued efforts to reduce general and administrative 
costs where appropriate.

Product warranty expense in fiscal 1998 of $1,500,000 was an estimate of 
anticipated costs related to a fungicide found in a product sold by the 
Company. This estimate was recorded in the fourth quarter of the fiscal year, 
since the discovery of the substance was made in May 1998. The reserve 
related to potential product returns, re-work costs, development work 
required to provide methodology to remove the substance from the bulk 
extracts and legal and professional fees. This reserve has been fully 
utilized, and was adequate to cover substantially all costs related to this 
situation.

INTEREST INCOME. Interest income was $315,280 in fiscal 1998, $528,424 in 
fiscal 1997 and $1,047,734 in fiscal 1996. The decreases are due to less 
capital available for investment.

OTHER INVESTMENTS. The Company sold its investment in a public company and 
realized a gain of $361,461 in fiscal 1998.

WRITEDOWN OF OTHER INVESTMENT. In April 1996, the Company's investment in a 
development stage company was written down resulting in a loss of $1,000,000. 
The investment was liquidated in the first quarter of fiscal 1997.

LIQUIDITY AND CAPITAL RESOURCES
   
GENERAL. Total cash and cash equivalents were $2,081,796 at April 30, 1998 
compared to $8,379,551 at April 30, 1997. The decrease is due primarily to 
capital expenditures, raw material purchases for new product areas, advances 
on growing contracts, and other general working capital requirements. The 
Company had a revolving line of credit totaling $8,850,000 which expired on 
June 30, 2000. As of April 30, 1998, $7,350,000 was available for use under 
this line of credit. Under the terms of the loan agreement, all assets of the 
Company, with the exception of intangibles, are secured by the bank. Under 
the terms of the lending agreement, the Company cannot pay any dividends 
without the consent of the bank and is required to maintain certain financial 
ratios and minimum working capital and equity amounts. As of April 30, 1998, 
the Company was not in compliance with a financial covenant for the line of 
credit which required the Company to report profitability in the fourth 
quarter of fiscal 1998. The Company has obtained a waiver from the bank for 
this covenant as of April 30, 1998.
    

                                   - 9 -                            Appendix F

In addition, the Company has a lease credit line with a bank of $564,000; as 
of April 30, 1998, $346,083 was available for use under this line. The 
Company's current line of credit requires that a restricted cash balance be 
maintained equal to one year's debt service of the outstanding line. This 
account can only be used to reduce the line of credit or pay interest. The 
restricted cash will be released upon the consummation of the merger and the 
refinancing of the Company's existing line of credit pursuant to the 
refinancing commitment secured from Wells Fargo.
    
   
The merger agreement entered into on December 8, 1998, includes a commitment 
from Wells Fargo Bank, N.A. to provide two credit facilities for an aggregate 
amount of $45.0 million to be guaranteed by each of its subsidiaries: a 
revolving line of credit up to $35.0 million for general working capital 
purposes maturing two years after the loan closing, and a $10.0 million 
non-revolving term commitment for financing the acquisition of fixed assets 
with a draw down period of two years and a maturity date of five years 
following the loan closing. The interest rate on the revolving credit 
facility is the Bank's prime rate minus 0.75% per annum or the Bank's quoted 
LIBOR rate plus 1.5 % per annum. For the term loan fixed asset facility, the 
interest rate is the Bank's prime rate minus 0.5% per annum or the Bank's 
quoted LIBOR plus 1.75 % per annum or on a specific fixed rate basis. A 
commitment fee will be charged of 0.25% per annum on the unused portion of 
the term loan fixed asset commitment. Management believes that current cash 
reserves and the credit facility commitments described above are sufficient 
to meet the Company's future liquidity needs and sufficient to fund 
anticipated merger and integration cost. Further, management believes that 
funds generated from business opportunities discussed earlier, will be 
sufficient to meet the liquidity needs of the Company on a long-term basis.
    
   
The Company was not in compliance with the financial covenants associated 
with its line of credit as of April 30, 1998, July 31, 1998, October 31, 1998 
and January 31, 1999. The Company has obtained waivers from the bank. 
Management believes that the financial covenants will not be met as of April 
30, 1999 and is planning on obtaining a waiver from the bank. However, the 
Company believes that the covenants associated with the new credit facility 
with Wells Fargo Bank N.A. will be met based on the forecasted operating 
results once the anticipated merger is completed.
    
   
In the process of exiting the paclitaxel business, management intends to 
negotiate early settlements with its growers of cultivated yew trees. 
Management estimates these settlement costs to be approximately $5.0 million 
and have been included in the one-time charge to earnings noted before. The 
cost to negotiate out of these contracts is expected to be funded from the 
sale of paclitaxel assets.
    
WORKING CAPITAL. Working capital as of April 30, 1998 was $16,671,596 
compared to $21,162,501 as of April 30, 1997. This decrease is primarily 
attributable to the use of cash to fund deposits on growing contracts of 
$2,599,619 and capital expenditures of $1,994,285. Further, current 
borrowings increased $1,739,582 primarily due to a $1,500,000 increase in the 
line of credit and a one time product warranty reserve of $1,500,000.

PROPERTY AND EQUIPMENT. Purchases of property and equipment in fiscal 1998 
totaled $2,058,167. This was primarily the result of improvements to 
manufacturing equipment for the production of nutraceuticals and food 
ingredients products.
   
The Company expects capital expenditures to be approximately $3.0 million in 
fiscal 1999 for additional manufacturing equipment improvements. The Company 
expects capital expenditures to increase significantly in fiscal 2000 pending 
the merger with ZGNA and expects to fund these capital expenditures through 
the $10.0 million non-revolving term commitment described above.
    
   
INCOME TAXES. The Company has a net deferred tax asset of $3,579,773 that has 
been reduced by a valuation allowance of $623,280 to $2,956,493 as of April 
30, 1998. In assessing the $2,956,493 considered realizable, management has 
considered the following factors: (1) taxable income projected within the 
next twenty-four months; (2) the expiration dates of its net operating loss 
and tax credit carryovers; (3) tax planning strategies which would allow 
Hauser to generate significant taxable income from existing assets (including 
possible sale-lease back scenarios for its land, property and equipment held 
fee simple); and (4) alternative strategies for its paclitaxel business. The 
amount of the deferred tax asset considered realizable could be reduced in 
the near term if estimates of future taxable income do not materialize.
    
The proposed merger has been structured as a tax-free reorganization within 
the meaning of Section 368(a) of the Internal Revenue Code of 1986, as 
amended (the "Code"). Management believes that substantially all of the 
excess purchase price will be allocated to non-deductible goodwill. In 
addition, the Company's use of its current net operating loss carryforward 
may be limited in the future if ZGNA's ownership exceeds 50%, as defined in 
Section 382 of the Code, within three years of the merger. Thus, management 
believes that the proposed merger will not have a significant impact on the 
company's recorded deferred tax assets. Further, because of the substantial 
uncertainties included with integrating the operations of Hauser and ZGNA, 
management believes that the merger will have no immediate effect on the 
combined Company's ability to realize its deferred tax assets.

BACKLOG. Backlog of unfilled purchase orders was $2,974,817 of as April 30, 
1998, compared to $4,370,876 as of April 30, 1997. Backlog consists of 
unfilled purchase orders for nutraceuticals and flavors products.

Total revenues increased 30% to $9,285,126 in the third quarter of fiscal 
1999, from $7,118,169 in the third quarter of fiscal 1998, the result of 
higher revenues in each of the Company's business units. For the nine months 
ended January 31, 1999, total revenues increased 25% over the same period 
last year, with increased revenues in Natural Ingredients and Technical 
Services offset by a decrease in Pharmaceuticals revenues.
    
   
NATURAL INGREDIENTS:
Natural ingredients product revenues increased 79% and 36% in the three and nine
months ended January 31, 1999, respectively, as compared to the same periods in
the prior fiscal year.
    
   
The increases are primarily attributable to success in selling nutraceutical 
products. In the quarter ended January 31, 1999, nutraceuticals revenues were 
$3,503,741, an increase of $1,487,263, or 74%, over revenues of $2,016,478 in 
the same quarter last year. In the nine months ended January 31, 1999, 
nutraceuticals revenues were $9,266,356, an increase of 36% over revenues of 
$6,814,235 in same period last year.
    
   
Sales of natural food ingredients were $411,947 in the quarter ended January 
31, 1999, an increase of 145% over revenues of $168,367 in the quarter ended 
January 31, 1998. For the nine months ended January 31, 1999, revenues from 
these products were $991,225, a 42% increase over revenues of $698,443 in the 
nine months ended January 31, 1998. These increases were the result of higher 
sales of rosemary extract products sold into the beverage industry.
    
   
TECHNICAL SERVICES:
Technical Services revenues were $4,471,668 in the quarter ended January 31,
1999, compared to $4,283,919 in the quarter ended January 31, 1998, an increase
of 4%. This slowdown in growth is the result of manpower limitations that
management is addressing through aggressive recruiting activities. Management
does not believe that this situation will have material negative effects on
future operations. In the nine months ended January 31, 1999, Technical Services
revenues were $12,784,147, a 27% increase over revenues of $10,062,162 for the
same period last year. These increases were because of ongoing natural products,
custom synthesis and drug development projects at Hauser Laboratories, as well
as increasing revenues from Shuster Laboratories attributable to the TAQA-TM-
program and the Foods 2000 initiative.
    

                                   - 13 -                           Appendix F

PHARMACEUTICALS:
Revenues from pharmaceutical products in the quarter ended January 31, 1999,
increased 38% to $897,770, compared to $649,405 in the same quarter one year
ago. This is the result of contractual royalty revenues associated with the
August 13, 1998 signing of a supply contract with Immunex to provide them and
their collaborative partner IVAX, with bulk paclitaxel. In the quarter ended
January 31, 1999, these high-margin revenues were $291,000. For the nine months
ended January 31, 1999, revenues declined 9% from the same period one year ago
because of lower sales of paclitaxel.
    
   
GROSS PROFIT. Total gross profit in the three and nine months ended January 
31, 1999, includes a one-time charge of $19.7 million for the write-down of 
paclitaxel related inventory to its estimated net realizable value, a 
write-down of advance payments made for the purchase of cultivated yew trees, 
and estimated costs for terminating yew tree cultivar contracts. This is part 
of the total charge taken in the third quarter of fiscal 1999 of $25.6 
million to reflect the Company's decision to exit the paclitaxel business.
    
   
Excluding the one-time charge, gross profit for the Company was 21.4% and 
21.6% of total revenues in the quarters ended January 31, 1999, and 1998, 
respectively, and 25.8% and 20.5% of total revenues in the nine month periods 
ended January 31, 1999, and 1998, respectively. The increases are the result 
of improved efficiencies in the manufacturing process. In the three and nine 
month periods ended January 31, 1999, gross profit for the natural products 
industry segment was 18.0% and 24.4% of total natural product revenues, 
respectively. In the three and nine month periods ended January 31, 1998, 
gross profit for the natural products industry segment was 2.6% and 8.6% of 
total natural product revenues, respectively. The Company's gross margin 
percentage has increased in the three and nine month periods ended January 
31, 1999 because of increased volume resulting in manufacturing efficiencies, 
better absorption of fixed costs and lower per unit costs. In the third 
quarter of fiscal 1999, the Company did experience higher manufacturing costs 
related to lack of high quality biomass, which negatively impacted gross 
margins from nutraceutical products. The quality of biomass will always be 
important to margins because better quality material will positively impact 
yield outputs. Management has implemented research programs to identify 
methodologies to improve biomass quality. Future results could be negatively 
impacted by the quality of biomass, although it is not possible to predict 
the exact amount.
    
   
Gross profit for technical services in the three months and nine months ended 
January 31, 1999, and 1998, was 25.1% and 27.4%, respectively, as compared to 
30.8% and 28.3% in the three and nine months ended January 31, 1998, 
respectively. These changes are the result of a change in the mix of 
technical service projects, which can alter gross profit quarter-to-quarter.
    
   
OPERATING EXPENSES. Research and development expenses were $318,581 in the 
quarter ended January 31, 1999, compared to $536,128 in the quarter ended 
January 31, 1998, a decrease of almost 41%. Research and development expenses 
in the nine months ended January 31, 1999, were $1,136,479, a decrease of 37% 
compared to the same period last year. These decreases in research and 
development costs were because some R&D employees were deployed to work on 
billable projects in the Technical Services business unit, the result of 
increasing customer

projects. As new staff is hired in Technical Services, the R&D personnel will 
go back to their research assignments. The Company intends to actively 
continue research and development efforts, and expects research and 
development expenses to return to their historical levels.
    
   
Sales and marketing expenses in the quarter ended January 31, 1999, were 
$624,314, an increase of $62,619, or 11% over the same three-month period 
last year. Sales and marketing expenses in the nine months ended January 31, 
1999, were $2,120,511, an increase of $487,110, or 30% over the same 
nine-month period last year. The increases represent the Company's 
accelerated efforts to market new products, particularly in the areas of 
nutraceuticals and natural food ingredients. The Company added new staff and 
increased spending on advertising and marketing materials for launches of new 
products, such as TT550-TM-, a ginger-based product for motion sickness. 
Further, higher commission costs were incurred as a result of higher revenues.
    
   
General and administrative expenses were $1,546,238 in the third quarter of 
fiscal 1999, a 2% increase compared to general and administrative expenses in 
the same quarter of fiscal 1998. For the nine months ended January 31, 1999, 
general and administrative costs were $4,848,124, an 11% increase over the 
same period last year. These increases are the result of staff additions and 
additional depreciation expense on certain new leasehold improvements.
    
   
In the three and nine months ended January 31, 1999, the Company recognized a 
charge to operating expenses of $5.9 million as part of the total write-down 
taken in the third quarter of fiscal 1999 of $25.6 million to reflect the 
Company's decision to exit the paclitaxel business. This operating expense 
charge includes the write-down of paclitaxel related equipment and 
intangibles.
    
   
INTEREST INCOME/EXPENSE. Interest income was $29,713 and $79,521 in the three 
and nine months ended January 31, 1999, respectively, compared to $81,363 and 
$281,240 in the three and nine months ended January 31, 1998, respectively. 
The decrease is the result of less capital available for investment. Interest 
expense in the three and nine-month periods ended January 31, 1999, was 
$190,653 and $370,131, respectively, compared to $3,380 and $10,043 in the 
three and nine-month periods ended January 31, 1998, respectively. The 
increases reflect the Company's use of its line of credit during fiscal 1999.
    
   
OTHER INCOME. Other income was $42,037 and $361,461 for the nine months ended 
January 31, 1999, and 1998, respectively. The decrease in other income is due 
to the sale of certain investments held by the Company in fiscal 1998 and the 
associated gains from these sales.
    
   
INCOME TAXES. The Company has not benefited its net loss for the three and 
nine months ended January 31, 1999, because of uncertainty regarding its 
realization. The Company has a net deferred income tax asset of $2,959,306 as 
of January 31, 1999. The deferred tax assets are recorded net of a valuation 
allowance of approximately $11 million as of January 31, 1999. In assessing 
the amount of its net deferred tax assets considered realizable, management 
has considered the following factors: (1) taxable income projected within the 
next twenty-four months; (2) the expiration dates of its net operating loss 
and tax credit carryovers; (3) tax planning strategies which would allow 
Hauser to generate significant taxable income from

                                   - 15 -                           Appendix F

<PAGE>


existing assets (including possible sale-lease back scenarios for its land, 
property and equipment held fee simple); and (4) its planned exit from the 
paclitaxel business. The amount of the deferred tax asset considered 
realizable could be reduced in the near term if estimates of future taxable 
income do not materialize.
    

The proposed merger has been structured as a tax-free reorganization within 
the meaning of Section 368(a) of the Internal Revenue Code of 1986, as 
amended (the "Code"). Management believes that substantially all of the 
excess purchase price will be allocated to non-deductible goodwill. In 
addition, the Company's use of its current net operating loss carryforward 
may be limited in the future if ZGNA's ownership exceeds 50%, as defined in 
Section 382 of the Code, within three years of the merger. Thus, management 
believes that the proposed merger will not have a significant impact on the 
company's recorded deferred tax assets. Further, because of the substantial 
uncertainties included with integrating the operations of Hauser and ZGNA, 
management believes that the merger will have no immediate effect on the 
combined Company's ability to realize its deferred tax assets.

LIQUIDITY AND CAPITAL RESOURCES
   
GENERAL. Total unrestricted cash and cash equivalents were $4,124,954 at 
January 31, 1999, compared to $2,081,796 at April 30, 1998. The increase is 
primarily the result of increased borrowings against the bank line of credit 
and a deposit related to the sale of inventory, offset by purchases of raw 
material inventory and the acquisition of capital equipment.
    
   
The Company has a revolving line of credit totaling $7.0 million which 
expires on May 15, 1999. As of January 31, 1999, the Company had borrowed 
$6.0 million under this line and $731,084 had been applied against letters of 
credit for the purchase of raw materials. The Company expects to pay the 
balance of this line of credit from the new credit facility with Wells Fargo 
Bank, N.A. as a result of the anticipated merger with Zuellig. Under the 
terms of the loan agreement, all assets of the Company, with the exception of 
intangibles, are secured by the bank. Additionally, the Company has a lease 
credit line with a bank of $500,000; as of January 31, 1999, $350,861 was 
available for use under this line. The Company's current line of credit 
requires that a restricted cash balance be maintained equal to one year's 
debt service of the outstanding line. This account can only be used to reduce 
the line of credit or pay interest. The restricted cash will be released upon 
the consummation of the merger and the refinancing of the Company's existing 
line of credit pursuant to the refinancing commitment

                                   - 16 -                           Appendix F

<PAGE>

secured from Wells Fargo. The Company does not use derivatives to manage its 
interest rate risk.
    
   
The merger agreement entered into on December 8, 1998, includes a commitment 
from Wells Fargo Bank, N.A. to provide two credit facilities for an aggregate 
amount of $45.0 million to be guaranteed by each of its subsidiaries: a 
revolving line of credit up to $35.0 million for general working capital 
purposes maturing two years after the loan closing, and a $10.0 million 
non-revolving term commitment for financing the acquisition of fixed assets 
with a draw down period of two years and a maturity date of five years 
following the loan closing. The interest rate on the revolving credit 
facility is the Bank's prime rate minus 0.75% per annum or the Bank's quoted 
LIBOR rate plus 1.5 % per annum. For the term loan fixed asset facility, the 
interest rate is the Bank's prime rate minus 0.5% per annum or the Bank's 
quoted LIBOR plus 1.75 % per annum or on a specific fixed rate basis. A 
commitment fee will be charged of 0.25% per annum on the unused portion of 
the term loan fixed asset commitment. Management believes that current cash 
reserves and the credit facility commitments described above are sufficient 
to meet the Company's future liquidity needs and sufficient to fund 
anticipated merger and integration cost. Further, management believes that 
funds generated from business opportunities discussed earlier, will be 
sufficient to meet the liquidity needs of the Company on a long-term basis.
    
   
The Company was not in compliance with the financial covenants associated 
with its line of credit as of April 30, 1998, July 31, 1998, October 31, 1998 
and January 31, 1999. The Company has obtained waivers from the bank. 
Management believes that the financial covenants will not be met as of April 
30, 1999 and is planning on obtaining a waiver from the bank. However, the 
Company believes that the covenants associated with the new credit facility 
with Wells Fargo Bank N.A. will be met based on the forecasted operating 
results once the anticipated merger is completed.
    
   
In the process of exiting the paclitaxel business, management intends to 
negotiate early settlements with its growers of cultivated yew trees. An 
estimate of these settlement costs has been included in the one-time charge 
to earnings noted before, but the exact amount is uncertain at this time. The 
cost to terminate these contracts is expected to be funded from the sale of 
paclitaxel assets.
    
   
In connection with the Merger, Hauser executed an inventory purchase 
agreement with Zuellig which is intended to provide interim financing for 
Hauser. Included in Deposits as of January 31, 1999, is $3 million received 
pursuant to this agreement. The purchase price for the inventory is the lower 
of cost or market. At any time, Hauser may require Zuellig to resell to 
Hauser all or any portion of the inventory purchased by Zuellig at the same 
price at which Zuellig purchased the inventory and require Zuellig to 
purchase substantially similar raw material and finished product having a 
value substantially equivalent to the repurchased inventory. Hauser will 
recognize revenue from the transaction upon the sale of the inventory to an 
unrelated party.
    
   
WORKING CAPITAL. Working capital as of January 31, 1999, was $12,922,743 
compared to $16,671,596 as of April 30, 1998. This decrease is primarily 
attributable to drawn funds that

                                   - 17 -                           Appendix F

<PAGE>


were used to fund operating losses and purchase capital assets and to the 
estimated costs accrued to exit the paclitaxel business.
    
   
PROPERTY AND EQUIPMENT. Purchases of property and equipment in the first nine 
months of fiscal 1999, totaled $1,917,831. This was the result of new 
construction and improvements to manufacturing equipment for the production 
of nutraceuticals and food ingredients products. The Company also entered 
into new capital leases totaling $482,627 during the nine months ended 
January 31, 1999, primarily for laboratory equipment used in technical 
services. The Company expects future capital expenditures to be similar for 
the remainder of fiscal 1999. However, the Company expects expenditures to 
increase significantly in fiscal 2000 pending the merger with ZGNA and 
expects to fund these capital expenditures through the $10.0 million 
non-revolving term commitment described above.
    
YEAR 2000. The Year 2000 problem is the result of computer systems and 
programs recognizing a date using "00" as the year 1900 rather than the year 
2000, which could result in miscalculations or system failures. The term 
"Year 2000 compliant" means that all computers, computer systems, and 
software, including all firmware, microcode, and embedded software, will 
accurately and consistently process date data for all dates in the twentieth 
and twenty-first centuries (including leap year considerations and data) 
without any loss of functionality or performance. This processing includes 
calculating, comparing, sequencing, storing, retrieving, transmitting, 
receiving, sorting, and displaying date data when computers, computer 
systems, or software are used as stand-alone systems, or in combination with 
other software or hardware. These computer systems will function without 
interruption before, during, and after January 1, 2000, without any change in 
operation or performance associated with the advent of the new century. 
Additionally, these computer systems will respond to date data input in a way 
that resolves any ambiguity as to century in a defined and predetermined 
manner; and store and provide output of date data in ways that are 
unambiguous as to century. The term "software" includes, but is not limited 
to, firmware, embedded software, and microcode.
   
The Company has undertaken a thorough review of its current information 
technology ("IT") and non-IT systems. This review is expected to be a 
continuing process. Initial results of the testing and identification phase 
of the Company's core systems indicate that approximately one third of its 
desktop computer systems (approximately 100 machines) and less than one 
fourth of its other microprocessor or microcontroller-based equipment 
(approximately 20 machines) are in need of replacement for Year 2000 
compliance. The replacement of these machines is expected to be completed by 
October 1999. Cost of replacement is not expected to exceed $200,000. As the 
review progresses, this estimate could be revised. For the nine months ended 
January 31, 1999, the Company had expensed a total of $152,000 directly 
related to Year 2000 remediation efforts.
    
   
As another part of Year 2000-compliance review, the Company has also 
undertaken a logical process of updating or deleting software systems known 
to have problems handling two-digit date information properly. The Company 
has completed the testing and identification phase of the review of its core 
applications supporting accounting, human resources and manufacturing 
processes. Upgrade or replacement of these applications is expected to be 
completed in the
                                   - 18 -                           Appendix F

<PAGE>


spring of 1999. The net cost of these upgrades is not expected to exceed an 
additional $50,000. The review of other software applications is underway at 
this time.
    

The Company has also implemented a Year 2000 compliance inquiry program with 
its current and potential major vendors and suppliers as to both the status 
of their equipment and systems and any delays they anticipate in supplying 
goods and services to the Company. Management expects that this inquiry 
program will be completed by April 1, 1999. If a third party's systems are 
not Year 2000 compliant, that problem will be addressed directly with that 
third party.

Management recognizes that failure to meet all Year 2000 issues could result 
in significant degradation of the Company's ability to provide laboratory 
testing, to manufacture products, and to invoice customers and pay vendors. 
Management is addressing these issues directly, aggressively pursuing 
upgrading all mission-critical systems.

Management foresees the likely internal "worst case scenario" to be limited 
in scope, and could include a very small number of machines which may not 
handle date data correctly. In this event, processing of data will be shifted 
to other machines until replacement can be accomplished. No significant 
degradation of data collection or processing is anticipated.

The other major risk to normal operations could result from the inability of 
our suppliers to provide materials, products and services. The Company has 
begun identifying alternative sources or suppliers to alleviate such 
circumstances.

If, because of unforeseen circumstances, installed hardware and software 
systems cease to function on January 1, 2000, a disaster recovery contingency 
plan (currently being drafted) will be activated to handle the emergency 
situation. The disaster recovery plan is expected to include a disaster 
recovery computer center with sufficient equipment to allow the Company to 
continue data processing operations that will operate on a 24-hour-a-day 
basis until normal operations can be resumed. The Company has established 
relationships with several computer system vendors who will be contracted to 
provide the necessary hardware and software to support the contingency plan.

The Company plans to devote the necessary resources to resolve all 
significant Year 2000 issues in a timely manner.

SEASONALITY. The Company has experienced seasonality in its sales of 
nutraceutical products. Lower demand for these products is evident in the 
summer months and tends to increase in the fall and winter months.

   
    

   
FORWARD LOOKING STATEMENTS
    

Certain oral and written statements of management of the Company included 
herein and elsewhere may contain forward-looking statements within the 
meaning of Section 27A of the Securities Act of 1933 and Section 21E of the 
Securities Exchange Act of 1934, which are

intended to be covered by the safe harbors created thereby. These statements 
include the plans and objectives of management for future operations. The 
forward-looking statements included herein and elsewhere are based on current 
expectations that involve judgments which are difficult or impossible to 
predict accurately and many of which are beyond the control of the Company. 
Although the Company believes that the assumptions underlying the 
forward-looking statements are reasonable, any of the assumptions could be 
inaccurate and, therefore, there can be no assurance that the forward-looking 
statements will prove to be accurate. In light of the significant 
uncertainties inherent in the forward-looking statements, the inclusion of 
such information should not be regarded as a representation by the Company or 
any other person that the objectives and plans of the Company will be 
achieved.

INDEPENDENT AUDITORS' REPORT

To Zuellig Botanical Extracts, Inc. and Affiliates:

We have audited the accompanying combined balance sheets of Zuellig Botanical 
Extracts, Inc., ZetaPharm, Inc. and Wilcox Drug Company, Inc. (the 
"Companies"), all of which are under common ownership and common management, 
as of March 31, 1998 and 1997, and the related combined statements of income, 
stockholders' equity, and cash flows and for each of the three years in the 
period ended March 31, 1998.  These financial statements are the 
responsibility of the Companies' management.  Our responsibility is to 
express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing 
standards.  Those standards require that we plan and perform the audit to 
obtain reasonable assurance about whether the financial statements are free 
of material misstatement.  An audit includes examining, on a test basis, 
evidence supporting the amounts and disclosures in the financial statements.  
An audit also includes assessing the accounting principles used and 
significant estimates made by management, as well as evaluating the overall 
financial statement presentation.  We believe that our audits provide a 
reasonable basis for our opinion.

In our opinion, such financial statements present fairly, in all material 
respects, the combined financial position of the Companies as of March 31, 
1998 and 1997, and the combined results of their operations and their 
combined cash flows for each of the three years in the period ended March 31, 
1998 in conformity with generally accepted accounting principles.

ZUELLIG BOTANICAL EXTRACTS, INC. 
AND AFFILIATED COMPANIES

NOTES TO THE COMBINED FINANCIAL STATEMENTS
YEARS ENDED MARCH 31, 1998, 1997 AND 1996
- --------------------------------------------------------------------------------

1.   GENERAL AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     PRINCIPLES OF COMBINATION - The combined financial statements include the
     accounts of Zuellig Botanical Extracts, Inc. ("ZBE"), ZetaPharm, Inc.
     ("ZetaPharm") and Wilcox Drug Company, Inc. ("Wilcox," together with ZBE
     and ZetaPharm, the "Companies"), which are affiliated through common
     ownership and common management.  ZBE is a wholly owned subsidiary of
     Zuellig Botanicals, Inc. ("ZBI").  ZBI, ZetaPharm and Wilcox are wholly
     owned subsidiaries of Zuellig Group N.A., Inc. ("ZGNA").  All significant
     intercompany balances and transactions have been eliminated in combination.
     
     ZBE is a distributor of bulk standardized and non-standardized
     nutraceutical extracts to manufacturers of dietary supplements.  ZetaPharm
     is a distributor of bulk fine chemicals, excipients and active ingredients
     used in the manufacture of generic pharmaceuticals.  Wilcox is a supplier
     of wild gathered and cultivated botanical raw materials.  The botanical raw
     materials sold by Wilcox are used in the manufacture of nutraceutical
     extracts or the production of botanical powders, both of which are sold to
     manufacturers of dietary supplements.
     
     USE OF ESTIMATES - The preparation of financial statements in conformity
     with generally accepted accounting principles requires management to make
     estimates and assumptions that affect the reported amounts of assets and
     liabilities and disclosure of contingent assets and liabilities at the date
     of the financial statements and the reported amounts of revenues and
     expenses during the reporting period.  Actual results could differ from
     those estimates.
     
     CONCENTRATION OF CREDIT RISK - Financial instruments that subject the
     Companies to credit risk consist primarily of cash and accounts receivable.
     The Companies place cash with high quality financial institutions and have
     not experienced losses with respect to these items.  Concentration of
     credit risk with respect to accounts receivable is generally diversified
     due to the large number of entities composing the Companies' customer base
     and their geographic dispersion.  The Companies perform ongoing credit
     evaluations of their customers and maintain allowances for potential credit
     losses.
     
     In 1997, sales to one customer accounted for 11% of net sales.
     
     INVENTORIES - Inventories consist of botanical and herbal products held for
     resale and are stated at the lower of cost or market, with cost determined
     primarily by specific identification.
     
     PROPERTY - Property is stated at cost less accumulated depreciation and
     amortization.  Depreciation is provided for primarily using the
     straight-line method over estimated useful lives ranging from 2 to 15
     years.  Leasehold improvements are amortized over the shorter of the terms
     of the leases or the assets' estimated useful lives.


                                         -6-
<PAGE>

     IMPAIRMENT OF LONG-LIVED ASSETS - The Companies review the recoverability
     of long-lived and intangible assets to determine whether there has been any
     impairment whenever events or changes in circumstances indicate that the
     carrying amount of an asset may not be recoverable.  This assessment is
     performed based on the estimated future cash flows compared with the
     asset's carrying value.  If the future cash flows (undiscounted and without
     interest charges) are less than the carrying value, a write-down would be
     recorded to reduce the related asset to its estimated fair value. 
     
     INCOME TAXES - The Companies are included in ZGNA's consolidated federal
     income tax return and combined California franchise tax return.  California
     franchise taxes are allocated to the Companies based on factors used to
     apportion taxable income to ZGNA's subsidiaries.  Other state income taxes
     are recorded based on the Companies' separate income tax returns.  The
     benefits of state tax credits are utilized to the extent available to the
     combined group.  Federal income taxes are computed as if the Companies
     filed separate income tax returns. 
     
     Deferred income tax assets and liabilities are computed for differences
     between the financial statement and income tax bases of assets and
     liabilities.  Such deferred income tax asset and liability computations are
     based on enacted tax laws and rates applicable to years in which the
     differences are expected to reverse.  A valuation allowance is established,
     when necessary, to reduce deferred income tax assets to the amount expected
     to be realized.  Income tax expense is the tax payable or refundable for
     the year plus or minus the change during the year in deferred income tax
     assets and liabilities.
     
     ALLOCATION OF EXPENSES - ZBE was incorporated on August 27, 1998.  Prior to
     that time, the accounts of ZBE were not maintained on a stand-alone basis. 
     Revenues and, when practicable, expenses have been allocated between ZBI
     and ZBE on a specific identification basis.  Certain selling, general and
     administrative expenses have been incurred by ZBI during the ordinary
     course of business and are not specifically allocable to ZBI or ZBE.  In
     these instances, management has allocated expenses based on sales mix or a
     percentage of time spent on extract-related administrative duties.  The
     Companies' management believes that these methods of allocation are
     reasonable.
     
2.   INVENTORIES

     Inventories consist of the following:

3.   BANK BORROWINGS

     During 1998, the Companies, ZGNA and certain affiliates entered into
     various credit agreements with a bank whereby they may borrow up to
     $35,000,000 under a revolving credit agreement, with an additional
     $3,000,000 available upon approval by the bank, and up to $750,000 under a
     non-revolving line of credit with a term repayment option through December
     1, 1998 (the "1998 Credit Agreements").  Under the terms of the 1998 Credit
     Agreements, $3,000,000 is available for the issuance of letters of credit
     with a maximum term of 150 days.  Advances bear interest at either the
     bank's reference rate at the time of each borrowing or LIBOR plus 1.75%
     (rates at March 31, 1998 range from 7.51% to 8.5%).  


                                         -7-
<PAGE>

     The amount outstanding under the Companies' 1998 Credit Agreements was
     $10,305,683 at March 31, 1998.  The aggregate amount outstanding under the
     1998 Credit Agreements for ZGNA and its subsidiaries was $17,601,879 at
     March 31, 1998.  All borrowings are collateralized by receivables and
     inventories, and all borrowings are cross-guaranteed by the Companies, ZGNA
     and affiliates participating in the 1998 Credit Agreements.
     
     The 1998 Credit Agreements require the Companies, ZGNA and affiliates to
     maintain certain specified operating ratios, minimum tangible net worth and
     certain other requirements.  The agreements also require the bank's
     approval to incur additional indebtedness.  These 1998 Credit Agreements
     were superceded and replaced by the 1999 Credit Agreements, as discussed
     below.
     
     During December 1998, the 1998 Credit Agreements were extended for eight
     days.  On December 8, 1998 the Companies, ZGNA and its affiliates entered
     into various new credit agreements (the "1999 Credit Agreements") with a
     bank whereby they may borrow up to $38,000,000 under a revolving credit
     agreement, with an additional $6,500,000 available under a non-revolving
     loan commitment.  The 1999 Credit Agreements have a term repayment option
     through April 30, 1999.  Under the terms of the 1999 Credit Agreements,
     $1,500,000 is available for the issuance of letters of credit with a
     maximum term of 150 days.  Advances under the revolving line of credit bear
     interest at either prime minus .75% or LIBOR plus 1.5%.  Advances under the
     non-revolving loan commitment bear interest at either prime minus .5% or
     LIBOR plus 1.75%.  All borrowings are collateralized by receivables and
     inventories, and all borrowings are cross-guaranteed by the Companies, ZGNA
     and affiliates participating in the 1999 Credit Agreements.
     
     During 1997, the Companies, ZGNA and certain affiliates entered into
     various credit agreements (the "1997 Credit Agreements").  Advances accrue
     interest at either the bank's reference rate at the time of borrowing or
     LIBOR plus 1.85%.  The amount outstanding under the Companies' 1997 Credit
     Agreement was $19,106,429 at March 31, 1997.  These 1997 Credit Agreements
     were superceded and replaced by the 1998 Credit Agreements, discussed
     above.
     
     During 1996, the Companies, ZGNA and certain affiliates entered into
     various credit agreements (the "1996 Credit Agreements").  Advances bear
     interest at the bank's prime lending rate or LIBOR plus 2.5%, and
     acceptances bear interest at the bank's prevailing acceptance rate at the
     time of each borrowing.  The 1996 Credit Agreements were superceded and
     replaced by the 1997 Credit Agreements, discussed above.
     
4.   LONG-TERM DEBT

     Long-term debt at March 31, 1997 consisted of a note payable to a former
     Wilcox stockholder of $55,000.  The entire balance was repaid in 1998.

5.   LEASE COMMITMENTS

     The Companies lease their facilities and certain equipment.  At March 31,
     1998, future minimum rental payments required under operating leases that
     have initial or remaining noncancelable lease terms in excess of one year
     are as follows:

</TABLE>

     The facilities leases generally include provisions for rent escalation to
     reflect increased operating costs or require the Company to pay property
     taxes, maintenance and utility costs.  One lease includes a renewal option
     for an additional five-year term.

     Rent expense for the years ended March 31, 1998, 1997 and 1996 was
     $261,802, $256,654 and $255,872, respectively.

7.   RELATED PARTY TRANSACTIONS

     Amounts due to/from affiliates consist primarily of management fees,
     intercompany tax allocations and balances arising from product sales to
     ZBI.

     The Companies sold products to ZBI totaling $6,793,310, $5,029,129 and
     $5,958,205 during 1998, 1997 and 1996, respectively.

     The Companies incurred management fee expense with affiliates of
     approximately $1,601,163, $429,007 and $255,643 during 1998, 1997 and 1996,
     respectively.

8.   EMPLOYEE BENEFITS

     ZetaPharm has an employment contract with its president that provides for
     incentive compensation based on defined earnings.  Compensation expense
     recorded under this plan in 1998, 1997 and 1996 was approximately $306,000,
     $252,300 and $180,066, respectively.  The employment contract may be
     terminated by either party upon six months' notice.

     Wilcox has an executive bonus plan and incentive compensation arrangements
     for key employees based on an earnings formula.  Compensation expense of
     $32,207 and $367,382 was recorded under these plans in 1997 and 1996,
     respectively.  There was no compensation expense recorded in 1998.

     During 1998, the Companies established a 401(k) plan under which the
     Companies make matching contributions, as defined.  Additionally, the
     Companies make a 2% contribution based on the qualified employee's
     compensation to the individual's 401(k) account.  During 1998, the
     Companies recorded contribution expense of $140,879.

     During 1997 and 1996, the Companies provided a simplified employee pension
     plan under which the Companies made contributions based on a percentage of
     the qualified employee's compensation to the individual's retirement
     account under Internal Revenue Code Sec. 408(k).  Such percentage was 4%
     during 1997 and 1996 and amounted to $121,246 and $59,706, respectively. 
     This plan was terminated in 1998.

9.   ACCRUED ENVIRONMENTAL CLEANUP COSTS

     On March 15, 1994, Wilcox and 78 other potentially responsible parties
     executed a consent decree with the Environmental Protection Agency ("EPA"),
     in accordance with the Comprehensive Environmental Response, Compensation
     and Liability Act for the cleanup of a designated Superfund Site.  Wilcox
     accrued a liability for the environmental cleanup costs of $1.5 million in
     fiscal 1994.  During 1997, Wilcox was informed that the EPA had
     substantially reduced its estimate with respect to the cleanup costs and
     counsel advised that it believed that Wilcox would not be required to make
     additional payments with respect to the cleanup.  Accordingly, management
     reversed substantially all of the remaining accrued environmental cleanup
     costs.

11.  SUBSEQUENT EVENTS

     On December 9, 1998, ZGNA and ZBI announced that ZBE, ZetaPharm and Wilcox
     will merge with Hauser Inc. ("Hauser"), a non-affiliated manufacturer of
     natural products headquartered in Boulder, Colorado.  Hauser will also have
     an option to acquire the powders business of ZBI.  Upon closing, ZGNA and
     ZBI will own collectively up to 10.05 million shares, representing
     approximately 49% of Hauser's outstanding common stock.  The agreement is
     subject to approval by Hauser's shareholders and customary closing
     conditions. 

     During 1999, ZetaPharm's principal generic ingredient supplier elected to
     sell its products directly, rather than utilize ZetaPharm as its
     distributor.  ZetaPharm's sales of generic ingredients represented 33%, 31%
     and 21% of the Companies' combined net sales for the years ended March 31,
     1998, 1997 and 1996, respectively.  Management expects that the revenue
     from the sale of generic ingredients will significantly decline in fiscal
     year 1999, and will be insignificant in fiscal year 2000.

      adjustments) necessary to present fairly the Companies' financial position
      as of January 31, 1999, and results of their operations and their cash 
      flows for the periods ended January 31, 1999 and 1998.
    
      USE OF ESTIMATES - The preparation of financial statements in conformity
      with generally accepted accounting principles requires management to make
      estimates and assumptions that affect the reported amounts of assets and
      liabilities and disclosure of contingent assets and liabilities at the
      date of the financial statements and the reported amounts of revenues and
      expenses during the reporting period. Actual results could differ from
      those estimates.
   
      ALLOCATION OF EXPENSES - ZBE was incorporated on August 27, 1998. Prior to
      that time, the accounts of ZBE were not maintained on a stand-alone basis.
      Revenues and, when practicable, expenses have been allocated between ZBI
      and ZBE on a specific identification basis. Certain selling, general and
      administrative expenses have been incurred by ZBI during the ordinary
      course of business, and are not specifically allocable to ZBI or ZBE. In
      these instances, management has allocated expenses based on sales mix or a
      percentage of time spent on extract-related administrative duties. The
      Companies' management believes that these methods of allocation are
      reasonable.

      3. BANK BORROWINGS
   
      Short-term bank borrowings consist of a line of credit. During 1998, the
      Companies, ZGNA and certain affiliates entered into various credit
      agreements with a bank under which they may borrow up to $35,000,000 under
      a revolving credit agreement with an additional $3,000,000 available upon
      approval by the bank, and up to $750,000 under a non-revolving line of
      credit with a term repayment option through December 1, 1998 (the "1998
      Credit Agreements"). Under the terms of the 1998 Credit Agreements,
      $3,000,000 was available for the issuance of letters of credit with a
      maximum term of 150 days. Advances bear interest at either the bank's
      reference rate at the time of each borrowing or LIBOR plus 1.75% (rates at
      March 31, 1998 range from 7.51% to 8.5%). The amount outstanding under the
      Companies' 1998 Credit Agreements was $10,305,683 at March 31, 1998.
    
   
      During December 1998, the 1998 Credit Agreements were extended for eight
      days. On December 8, 1998 the Companies, ZGNA and its affiliates entered
      into various new credit agreements (the "1999 Credit Agreements") with a
      bank under which they may borrow up to $38,000,000 under a revolving
      credit agreement with an additional $6,500,000 available under a
      non-revolving loan commitment. The 1999 Credit Agreements have a term
      repayment option through April 30, 1999. Under the terms of the 1999
      Credit Agreements, $1,500,000 is available for the issuance of letters of
      credit with a maximum term of 150 days. Advances under the revolving line
      of credit bear interest at either prime minus .75% or LIBOR plus 1.5%.
      Advances under the non-revolving loan commitment bear interest at either
      prime minus .5% or LIBOR plus 1.75% (rates at January 31, 1999 range from
      6.51% to 7.0%). The amount outstanding under the Companies' 1999 Credit
      Agreements was $20,633,583 at January 31, 1999. The aggregate amount
      outstanding under the 1999 Credit Agreements for ZGNA and its subsidiaries
      was $38,859,315 at January 31, 1999. All borrowings are collateralized by
      receivables and inventories, and all borrowings are cross-guaranteed by 
      the Companies, ZGNA and affiliates participating in the credit agreements.

      4. RELATED PARTY TRANSACTIONS
   
      Amounts due to/from affiliates consist primarily of management fees,
      intercompany tax allocations and balances arising from product sales to
      ZBI.
    
   
      The Companies sold products to ZBI totaling $9,323,067 and $5,156,613
      during the ten months ended January 31, 1999 and 1998, respectively.
      Historically, products were sold to ZBI at margins comparable to margins
      generated from sales to third parties. During 1999, it was contemplated
      that Wilcox would merge into ZBI, and accordingly, all sales to ZBI 
      during the ten months ended January 31, 1999 were made at cost.
    
   
      Management fees are charged based on a net funds employed formula, derived
      from key balance sheet accounts. The Companies incurred management fee
      expense with affiliates of $870,176 and $832,716 during the ten months
      ended January 31, 1999 and 1998, respectively.
    
   
      5. PROPOSED MERGER
    
      On December 9, 1998, ZGNA and ZBI announced that ZBE, ZetaPharm and Wilcox
      will merge with Hauser Inc. ("Hauser"), a non-affiliated manufacturer of
      natural products headquartered in Boulder, Colorado. Hauser will also have
      an option to acquire the powders business of ZBI. Upon closing, ZGNA and
      ZBI will own collectively up to 10.05 million shares, representing
      approximately 49% of Hauser's outstanding common stock. The agreement is
      subject to approval by Hauser's shareholders and customary closing
      conditions.
   
      6.  CONCENTRATION
    
   
      During 1999, ZetaPharms's principal generic ingredient supplier elected to
      sell its products directly, rather than utilize ZetaPharm as its
      distributor. ZetaPharm's sales of generic ingredients represented 40% 
      and 32% for the ten months ended January 31, 1999 and 1998, respectively. 
      Management expects that the revenue from the sale of generic ingredients 
      will significantly decline in fiscal year 1999 and will be insignificant 
      in fiscal year 2000.

of the Company and promoting an identity of interest between stockholders of 
the Company and these employees and consultants.

     So that the appropriate incentive can be provided, the Plan allows for

4.   ADMINISTRATION

     The Board or the Committee shall administer the Plan.  The Company shall

     thereto shall thereupon be released and shall thereafter be available for
     new Options under the Plan;

                                      -5-
<PAGE>

7.   OPTION TERMS

     The Committee is authorized to grant one or more Incentive Stock Options 
or Nonqualified Stock Options to any Eligible Person; PROVIDED, HOWEVER, that 
no Incentive Stock Options shall be granted to any Eligible Person who is not 
an employee of the Company or a Subsidiary.  Each Option so granted shall be 
subject to the following conditions, or to such other conditions as may be 
reflected in the applicable Option Agreement.

     (a)  OPTION PRICE.  The Option Price per share of Stock for each Option 
shall be set by the Committee at the time of grant but, shall not be less 
than the Fair Market Value of a share of Stock at the date of grant.

     (b)  MANNER OF EXERCISE AND FORM OF PAYMENT.  Options which have become 
exercisable may be exercised by delivery of written notice of exercise to the 
Committee accompanied by payment of the Option Price.  The Option Price shall 
be payable in cash or by certified check or, in the discretion of the 
Committee, (i) in shares of Stock, valued at the Fair Market Value at the 
time the Option is exercised, in sufficient amount to cover the aggregate 
exercise price (provided that such Stock must have been held by the Optionee 
for at least six months prior to exercise of the Option), (ii) by withholding 
shares of Stock, valued at the Fair Market Value at the time the Option is 
exercised, otherwise deliverable upon exercise of the Options, in sufficient 
amount to cover the aggregate exercise price; (iii) in other property having 
a fair market value on the date of exercise equal to the Option Price, or 
(iv) by delivering to the Committee a copy of irrevocable instructions to a 
stockbroker acceptable to the Company to deliver promptly to the Company an 
amount of sale or loan proceeds sufficient to pay the aggregate exercise 
price or (v) by delivery of a promissory note if in accordance with 
applicable state and federal law.

     (c)  OPTION PERIOD AND VESTING.  Options shall vest and become 
exercisable in such manner and on such date or dates as shall be determined 
by the Committee.  The Committee shall also establish an Option Period which 
shall not exceed ten years.  If an Option is exercisable in installments, 
exercise of one installment shall not affect the Optionee's ability to 
exercise unexercised installments in accordance with the terms of the Plan 
and the applicable Option Agreement.  Unless otherwise stated in the 
applicable Option Agreement, the Option shall expire upon an Optionee's 
termination of employment with the Company or a Subsidiary at such times as 
are set forth in Section 8.

     (d)  OTHER TERMS AND CONDITIONS.  Options granted under the Plan shall 
be evidenced by an Option Agreement, which shall contain such provisions as 
may be determined by the Committee and, except as may be specifically stated 
otherwise in such Option Agreement, be subject to the following terms and 
conditions:

          (i)   Each share of Stock purchased through the exercise of an Option
                shall be paid for in full at the time of the exercise.  Each
                Option shall cease to be exercisable when the Optionee
                purchases the underlying share of Stock or when the Option
                expires.


                                      -6-
<PAGE>

          (ii)  Options shall not be transferable by the Optionee except by
                will or the laws of descent and distribution and shall be
                exercisable during the Optionee's lifetime only by the
                Optionee.

          (iii) Subject to any accelerated vesting, each Option shall vest and
                become exercisable by the Optionee in accordance with the
                vesting schedule established by the Committee and set forth in
                the Option Agreement.

          (iv)  Each Option Agreement covering Incentive Stock Options shall
                contain a provision requiring the Optionee to notify the
                Company in writing immediately after the Optionee makes a
                disqualifying disposition of any Stock acquired pursuant to the
                exercise of any such Incentive Stock Option.  A disqualifying
                disposition is any disposition (including any sale) of such
                Stock before the later of (a) two years after the date of grant
                of the Incentive Stock Option or (b) one year after the date
                the Optionee acquired the Stock by exercising the Incentive
                Stock Option.

          (v)   Each Option Agreement may contain such other provisions
                (whether or not applicable to an Option granted to any other
                Optionee) as the Committee determines appropriate including,
                without limitation, provisions to assist the Optionee in
                financing the purchase of Stock upon the exercise of Options
                which are consistent with applicable state and federal law,
                provisions for the forfeiture of shares of Stock or
                restrictions on resale or other disposition of shares of Stock
                acquired under any Option, provisions giving the Company the
                right to repurchase shares of Stock acquired under any Option
                in the event the Optionee elects to dispose of such shares or
                terminates employment with the Company and its Subsidiaries,
                and provisions to comply with Federal and state securities laws
                and Federal and state tax withholding requirements.  Any such
                provisions shall be reflected in the applicable Option
                Agreement.

     (e)  INCENTIVE STOCK OPTION GRANTS TO 10% STOCKHOLDERS.  Notwithstanding 
anything to the contrary in this Section 7, if an Incentive Stock Option is 
granted to an Optionee who owns stock representing more than ten percent of 
the voting power of all classes of stock of the Company,  its parent or a 
subsidiary (as provided in Section 422(b) of the Code), the Option Period 
shall not exceed five years from the date of grant of such Option and the 
Option Price shall be at least 110 percent of the Fair Market Value (on the 
Date of Grant) of the Stock subject to the Option.

     (f)  $100,000 PER YEAR LIMITATION FOR INCENTIVE STOCK OPTIONS.  To the 
extent the aggregate Fair Market Value (determined as of the date of grant) 
of Stock for which Incentive Stock Options are exercisable for the first time 
by any Optionee during any calendar year (under all plans of the Company and 
its Subsidiaries) exceeds $100,000, the portion of the Options with respect 
to which such excess arises shall be treated as a Nonqualified Stock Options.

     (g)  VOLUNTARY SURRENDER.  The Committee may permit the voluntary 
surrender of any Nonqualified Stock Option to be conditioned upon the 
granting to the Optionee of a new Option for


                                      -7-
<PAGE>

the same or a different number of shares as the Option surrendered or require 
such voluntary surrender as a condition precedent to a grant of a new Option 
to such Optionee.  Such new Option shall be exercisable at an Option Price, 
during an Option Period, and in accordance with any other terms or conditions 
specified by the Committee at the time the new Option is granted, all 
determined in accordance with the provisions of the Plan without regard to 
the Option Price, Option Period, or any other terms and conditions of the 
Nonqualified Stock Option surrendered.

8.   EXPIRATION OF OPTION UPON TERMINATION OF EMPLOYMENT

     Except as otherwise determined by the Committee and set forth in an 
Option Agreement, the following provisions will apply to all Options upon an 
Optionee's termination of employment with the Company or a Subsidiary:

     (a)  If prior to the end of the Option Period the Optionee shall undergo 
a Normal Termination, all unvested Options then held by such Optionee shall 
expire on the date of Normal Termination and all vested Options then held by 
such Optionee shall expire on the earlier of the last day of the respective 
Option Period or the date that is three months after the date of such Normal 
Termination.  All vesting with respect to Options shall cease on the date of 
Normal Termination and all Options which are vested as of such date shall 
remain exercisable by the Optionee until their expiration as provided above.

     (b)  If the Optionee dies prior to the end of the Option Period and 
while still in the employ or service of the Company or a Subsidiary or within 
three months of Normal Termination, all unvested Options then held by such 
Optionee shall expire on the date of death and all other Options then held by 
such Optionee shall expire on the earlier of the last day of the respective 
Option Period or the date that is one year after the date of death of the 
Optionee. All vesting with respect to Options shall cease on the earlier of 
the date of Normal Termination or the date of death and all such Options 
which are vested as of such date shall remain exercisable by the beneficiary 
chosen by the Optionee pursuant to Section 9(e) or, if none has been chosen, 
by the person or persons to whom the Optionee's rights under the Options pass 
by will or the applicable laws of descent and distribution until their 
expiration as provided above.

     (c)  If an Optionee voluntarily ceases employment or service with the 
Company or a Subsidiary under circumstances where the Company or the 
Subsidiary could terminate the Optionee's employment or service for Cause or 
the Company or a Subsidiary terminates Optionee's employment or service for 
Cause, all Options then held by such Optionee, whether vested or unvested, 
shall expire immediately upon such cessation of employment or service.  If an 
Optionee voluntarily ceases employment or service with the Company or a 
Subsidiary other than as provided in other provisions of Section 8, all 
unvested Options then held by such Optionee shall expire on the date of 
cessation of employment or service and all vested Options then held by such 
Optionee shall expire on the earlier of the last day of the respective Option 
Period or the date that is three months after the date of such cessation.

9.   STOCK GRANTS TO DIRECTORS.  The Committee may, in its sole discretion, 
make grants of Stock to members of the Board who are not also employees of 
the Company or a Subsidiary in lieu of cash compensation for their services 
as members of the Board.  Grants of Stock under this Section 9 shall be in 
such amounts and have such terms as the Committee deems appropriate at the 
time of grant.

10.  GENERAL

     (a)  PRIVILEGES OF STOCK OWNERSHIP.  Except as otherwise specifically 
provided in the Plan, no person shall be entitled to the privileges of stock 
ownership in respect of shares of Stock which are subject to Options 
hereunder until such shares have been issued to that person.

     (b)  GOVERNMENT AND OTHER REGULATIONS.  The obligation of the Company to 
deliver shares of Stock upon the exercise of Options shall be subject to all 
applicable laws, rules, and regulations, and to such approvals by 
governmental agencies as may be required.  Notwithstanding any terms or 
conditions of any Option to the contrary, the Company shall be under no 
obligation to offer to sell or to sell and shall be prohibited from offering 
to sell or selling any shares of Stock pursuant to an Option unless such 
shares have been properly registered for sale pursuant to the Securities Act 
with the Securities and Exchange Commission or unless the Company has 
received an opinion of counsel, satisfactory to the Company, that such shares 
may be offered or sold without such registration pursuant to an available 
exemption therefrom and the terms and conditions of such exemption have been 
fully complied with.  The Company shall be under no obligation to register 
for sale under the Securities Act any of the shares of Stock to be offered or 
sold under the Plan.  If the shares of Stock offered for sale or sold under 
the Plan are offered or sold pursuant to an exemption from registration under 
the Securities Act, the Company may restrict the transfer of such shares and 
may legend the Stock certificates representing such shares in such manner as 
it deems advisable to ensure the availability of any such exemption.

     (c)  TAX WITHHOLDING.  Notwithstanding any other provision of the Plan, 
the Company or a Subsidiary, as appropriate, shall have the right to deduct 
from the number of shares of Stock issued upon the exercise of an Option such 
number of shares of Stock, valued at Fair Market Value on the date of 
payment, in an amount necessary to satisfy all Federal, state or local taxes 
as required by law to be withheld with respect to such Options.  In the 
alternative, at the sole discretion of the Committee, an Optionee or other 
person receiving Stock upon exercise of an Option may be required to pay to 
the Company or a Subsidiary, as appropriate, prior to delivery of such Stock, 
the amount of any such taxes which the Company or a Subsidiary, as 
appropriate, is required to withhold, if any, with respect to such Stock.  
Subject in particular cases to the disapproval of the Committee, the Company 
may accept shares of Stock of equivalent Fair Market Value in payment of such 
withholding tax obligations if the Optionee elects to make payment in such 
manner.  In furtherance of the foregoing, the Company may require that (i) 
shares of Stock surrendered have been owned by the Optionee for at least six 
months prior to the exercise or (ii) the Optionee, attesting in writing to 
the Company ownership of shares of Stock having a Fair Market Value at the 
time of attestation equal to such additional withholding obligations and 
allowing the Company to withhold from the shares such Optionee would 
otherwise receive an equal number of shares of Stock.

     (d)  CLAIM TO OPTIONS,  AND EMPLOYMENT RIGHTS.  No employee or other 
person shall have any claim or right to be granted an Option under the Plan 
or, having been selected for the grant of an Option, to be selected for a 
grant of any other Option.  Neither the Plan nor any action taken hereunder 
shall be construed as giving any Optionee any right to be retained in the 
employ or service of the Company or any Subsidiary. The grant of an Option 
does not imply that the Company


                                      -9-
<PAGE>

or any Subsidiary does not anticipate either a general reduction in force or 
the termination of the employment, directorship or consulting position of an 
Optionee. 

     The grant of a Stock Option does not create a fiduciary relationship 
between the Optionee and the Company or any other person or entitle the 
Optionee to require the Company or any other person to provide any 
information except as required by applicable securities or employee benefits 
statutes and rules and regulations issued thereunder. An Optionee shall have 
no rights as a shareholder with respect to any shares of Common Stock subject 
to an Option. 

     (e)  DESIGNATION AND CHANGE OF BENEFICIARY.  Each Optionee may file with 
the Committee a written designation of one or more persons as the beneficiary 
who shall be entitled to exercise the rights with respect to an Option 
granted under the Plan upon the Optionee's death.  An Optionee may, from time 
to time, revoke or change his beneficiary designation without the consent of 
any prior beneficiary by filing a new designation with the Committee.  The 
last such designation received by the Committee shall be controlling; 
PROVIDED, HOWEVER, that no designation, or change or revocation thereof, 
shall be effective unless received by the Committee prior to the Optionee's 
death, and in no event shall it be effective as of a date prior to such 
receipt. 

     (f)  PAYMENTS TO PERSONS OTHER THAN OPTIONEES.  If the Committee shall 
find that any person entitled to exercise an Option granted under the Plan is 
unable to care for his affairs because of illness or accident, or is a minor, 
then the delivery of shares of Stock due to such person or his estate upon 
such exercise (unless a prior claim therefor has been made by a duly 
appointed legal representative) may, if the Committee so directs the Company, 
be made to his spouse, child, relative, an institution maintaining or having 
custody of such person, or any other person deemed by the Committee to be a 
proper recipient on behalf of such person otherwise entitled to delivery.  
Any such delivery shall be a complete discharge of the liability of the 
Committee and the Company therefor.

     (g)  TIME OF EXERCISE.  Unless an earlier time is determined by the 
Committee, all exercises of Options during or within ten (10) days after the 
end of employment or service, may be processed by the Company five (5) days 
after notice of exercise is given by the Optionee.  If prior to the 
processing of any Option exercise the Company determines that it had as of 
the time of the end of employment or service or has as of the time of 
processing grounds to terminate the Option under Section 8(c), the Option may 
be canceled without exercise.

     (h)  NO LIABILITY OF COMPANY OR COMMITTEE MEMBERS.  No member of the 
Committee shall be personally liable by reason of any contract or other 
instrument executed by such member or on his behalf in his capacity as a 
member of the Committee nor for any mistake of judgment made in good faith, 
and the Company shall indemnify and hold harmless each member of the 
Committee and each other employee, officer or director of the Company to whom 
any duty or power relating to the administration or interpretation of the 
Plan may be allocated or delegated, against any cost or expense (including 
counsel fees) or liability (including any sum paid in settlement of a claim) 
arising out of any act or omission to act in connection with the Plan unless 
arising out of such person's own fraud or willful bad faith; PROVIDED, 
HOWEVER, that approval of the Board shall be required for the payment of any 
amount in settlement of a claim against any such person.  The foregoing right 
of indemnification shall not be exclusive of any other rights of 
indemnification to which such persons may be entitled under the Company's 
Articles of Incorporation or By-Laws, as a matter of law, or otherwise, or 
any power that the Company may have to indemnify them or hold


                                     -10-
<PAGE>

them harmless.  The Company, Subsidiaries, the Board and the Committee shall 
have no liability to the Optionee, or the Optionee's estate or transferee if: 
(i) an Option intended to be an Incentive Stock Option does not at any time 
qualify as an incentive stock option under the Code; (ii) an Option grant or 
exercise, or the subsequent sale of securities received on such exercise, 
does not qualify as exempt from the application of Section 16(b) of the 
Exchange Act; or (iii) an Option grant or exercise, or the subsequent sale of 
securities received on such exercise, is subject to Section 162(m) or 280G of 
the Code; in each case even if the Optionee, estate to transferee was 
informed it would qualify or not be so subject.

     (i)  GOVERNING LAW.  The Plan shall be governed by and construed in 
accordance with the internal laws of the State of Colorado applicable to 
contracts made and performed within such state, without regard to the 
principles of conflicts of law thereof, except as such laws may be supplanted 
by the federal laws of the United States of America, which laws shall then 
govern its effect and its construction to the extent they supplant Colorado 
law.

     (j)  RELIANCE ON REPORTS.  Each member of the Committee and each member 
of the Board shall be fully justified in relying, acting or failing to act, 
and shall not be liable for having so relied, acted or failed to act in good 
faith, upon any report made by the independent public accountant of the 
Company and its Subsidiaries and upon any other information furnished in 
connection with the Plan by any person or persons other than himself.

     (k)  RELATIONSHIP TO OTHER BENEFITS.  No payment under the Plan shall be 
taken into account in determining any benefits under any pension, retirement, 
profit sharing, group insurance or other benefit plan of the Company except 
as otherwise specifically provided in such other plan.

     (l)  EXPENSES.  The expenses of administering the Plan shall be borne by 
the Company. 

     (m)  PRONOUNS.  Masculine pronouns and other words of masculine gender 
shall refer to both men and women.

     (n)  TITLES AND HEADINGS.  The titles and headings of the sections in 
the Plan are for convenience of reference only, and in the event of any 
conflict, the text of the Plan, rather than such titles or headings shall 
control.

11.  CHANGES IN CAPITAL STRUCTURE

     Options granted under the Plan and any agreements evidencing such 
Options shall be subject to equitable adjustment or substitution, as 
determined by the Committee in its sole discretion, as to the number of 
shares, the exercise price, the price or kind of a share of Stock or other 
consideration subject to such Options (i) in the event of changes in the 
outstanding Common Stock or in the capital structure of the Company by reason 
of stock dividends, stock splits, reverse stock splits, recapitalizations, 
reorganizations, mergers, consolidations, combinations, exchanges, spinoffs, 
split-ups or other relevant changes in capitalization occurring after the 
date of grant of any such Option, (ii) in the event of any change in 
applicable laws or any change in circumstances which results in or would 
result in any substantial dilution or enlargement of the rights granted to,


                                     -11-
<PAGE>

or available for, Optionees in the Plan, or (iii) upon the occurrence of any 
other event which otherwise warrants equitable adjustment because it 
interferes with the intended operation of the Plan.  In addition, upon any 
such event, the aggregate number of shares of Stock available under the Plan 
and the maximum number of shares of Stock with respect to which any one 
person may be granted in connection with Options during any year, if 
applicable, shall be appropriately adjusted by the Committee, whose 
determination shall be conclusive.  With respect to Options intended to 
qualify as "performance-based compensation" under Section 162(m) of the Code, 
such adjustments or substitutions shall be made only to the extent that the 
Committee determines that such adjustments or substitutions may be made 
without a loss of deductibility for such Options under Section 162(m) of the 
Code.  The Company shall give each Optionee notice of an adjustment hereunder 
and, upon notice, such adjustment shall be conclusive and binding for all 
purposes. 

     Notwithstanding the above, in the event of any of the following:

          (a)   The Company is merged or consolidated with another corporation
     or entity and, in connection therewith, consideration is received by
     shareholders of the Company in a form other than stock or other equity
     interests of the surviving entity; 

          (b)   All or substantially all of the assets of the Company are
     acquired by another person; or

          (c)   The reorganization or liquidation of the Company; 

then the Committee may, in its sole discretion and upon at least 10 days 
advance notice to the affected persons, immediately prior to and subject to 
the consummation of such event cancel any particular or all outstanding 
Options (vested or unvested) and pay to the Optionees thereof, in cash, the 
value of such Options vested as of such cancellation (taking into account any 
acceleration of vesting as a result of such event) based upon the price per 
share of Stock received or to be received by other shareholders of the 
Company in the event.  The terms of this Section 10 may be varied by the 
Committee in any particular Option Agreement.

12.  CHANGE IN CONTROL

     (a)  Except to the extent reflected in a particular Option Agreement, in 
the event of a "Change in Control" (as defined below), notwithstanding any 
vesting schedule with respect to any Options, all then unexercised and 
unexpired Options which would otherwise be vested and exercisable within 12 
months after the Change in Control assuming a continuation of employment or 
service had occurred shall become immediately vested and exercisable.

     (b)  For purposes of the Plan, Change in Control shall, unless the Board 
otherwise directs by resolution adopted prior thereto or, in the case of a 
particular Option, the particular Option Agreement states otherwise, be 
deemed to occur if:

          (i)   Any person, entity or group (within the meaning of Section
                13(d)(3) of the Exchange Act, other than Zuellig Group,
                N.A. ("ZGNA") and/or its affiliates, becomes, directly or
                indirectly, by way of merger, consolidation or other business
                combination, or otherwise, the "beneficial owner" (as defined
                in Rule 13d-3 under the Exchange Act) of the capital stock of
                the Company


                                     -12-
<PAGE>

                entitled to more than 50% of the aggregate votes represented 
                by the capital stock of all classes of common stock of the 
                Company entitled to vote generally in the election of 
                directors ("Outstanding Voting Securities"); PROVIDED, HOWEVER,
                that the following acquisitions will not constitute a Change in
                Control: (i) any acquisition by any employee benefit plan (or
                related trust) sponsored or maintained by the Company or any
                Subsidiary (ii) any acquisition by any corporation pursuant to
                a reorganization, merger or consolidation, if, following such
                reorganization, merger or consolidation, the conditions
                described in clauses (A) and (B) of clause (iii) of this
                definition are satisfied or (iii)  ZGNA and/or its affiliates
                becomes directly or indirectly, by way of merger, consolidation
                or other business combination, or otherwise, the beneficial
                owner of more than 50% of the Outstanding Voting Securities
                otherwise than solely because of the issuance of Outstanding
                Voting Securities of the Company  pursuant to the Agreement for
                Option to Acquire Powders Business from Zuellig Botanicals,
                Inc. between the Company and Zuellig Botanicals, Inc., ("ZBI")
                dated _____, 1999, as amended or superseded from time to time.

          (ii)  individuals who, as of the effective date of the Plan,
                constitute the Board of Directors of the Company (the
                "Incumbent Board") cease for any reason to constitute at least
                a majority of the Company's Board of Directors; provided,
                however, that any individual becoming a director subsequent to
                the effective date of the Plan whose election, or nomination
                for election by the Company's shareholders was approved by a
                vote of at least a majority of the directors then comprising
                the Incumbent Board or pursuant to the Governance Agreement
                between the Company, ZGNA and ZBI, dated _________, 1999, will
                be considered as though such individual were a member of the
                Incumbent Board; or

          (iii) The occurrence of a reorganization, merger or consolidation, in
                each case, UNLESS, following such reorganization, merger or
                consolidation, (A) more than 50% of, respectively, the then
                outstanding shares of common stock of the corporation resulting
                from such reorganization, merger or consolidation and the
                combined voting power of the then outstanding voting securities
                of such corporation entitled to vote generally in the election
                of directors is then beneficially owned, directly or
                indirectly, by all or substantially all of the individuals and
                entities who were the beneficial owners, respectively, of the
                Outstanding Voting Securities immediately prior to such
                reorganization, merger or consolidation in substantially the
                same proportions as their ownership, immediately prior to such
                reorganization, merger or consolidation, of the Outstanding
                Voting Securities, and (B) at least a majority of the members
                of the board of directors of the corporation resulting from
                such reorganization, merger or consolidation were members of
                the Board at the time of the execution of the initial agreement
                providing for such reorganization, merger or consolidation; or

          (iv)  Approval by the shareholders of the Company of (A) a complete
                liquidation or dissolution of the Company, as applicable, or
                (B) the sale or other disposition of


                                     -13-
<PAGE>

                all or substantially all of the assets of the Company, 
                OTHER THAN to a corporation, with respect to which 
                following such sale or other disposition, (1) more than 
                50% of, respectively, the then outstanding shares of common 
                stock of such corporation and the combined voting power
                of the then outstanding voting securities of such corporation
                entitled to vote generally in the election of directors is then
                beneficially owned, directly or indirectly, by all or
                substantially all of the individuals and entities who were the
                beneficial owners, respectively of the Outstanding Voting
                Securities immediately prior to such sale or other disposition,
                in substantially the same proportion as their ownership
                immediately prior to such sale or other disposition, of the
                Outstanding Voting Securities, and (2) at least a majority of
                the members of the board of directors of such corporation were
                members of the Board at the time of the execution of the
                initial agreement or action of the Board providing for such
                sale or other disposition of assets of the Company; provided,
                however, that no transaction resulting in the disposition of
                one or more subsidiaries or other business units of the Company
                will be treated as substantially all of the assets of the
                Company unless the assets so disposed of comprise more than 70%
                of all corporate assets.

13.  NONEXCLUSIVITY OF THE PLAN

     Neither the adoption of this Plan by the Board nor the submission of 
this Plan to the stockholders of the Company for approval shall be construed 
as creating any limitations on the power of the Board to adopt such other 
incentive arrangements as it may deem desirable, including, without 
limitation, the granting of stock options otherwise than under this Plan, and 
such arrangements may be either applicable generally or only in specific 
cases.

14.  AMENDMENTS AND TERMINATION

     The Board may at any time terminate the Plan.  With the express written 
consent of an individual Optionee, the Board or the Committee may cancel or 
reduce or otherwise alter outstanding Options.  The Board or the Committee 
may, at any time, or from time to time, amend or suspend and, if suspended, 
reinstate, the Plan in whole or in part; provided, however, that no amendment 
which requires stockholder approval in order for Options granted pursuant to 
the Plan to be exempt from the application of Section 162(m) of the Code or 
for Options which are Incentive Stock Options to continue to meet the 
requirements of Section 422 of the Code, shall be effective unless the same 
shall be approved by the requisite vote of the stockholders of the Company.
     
15.  EFFECT OF SECTION 162(m) OF THE CODE
 
     The Plan, and all Options issued thereunder, are intended to be exempt 
from the application of Section 162(m) of the Code, which restricts under 
certain circumstances the Federal income tax deduction for compensation paid 
by a publicly held corporation to named executives in excess of $1 million

Committee determines as of the date of grant of an Option that (i) the Option 
is intended to comply with Section 162(m) of the Code and (ii) the exemption 
described above is not available with respect to such Option because the 
stockholders have not approved the Plan, such Option shall not be effective 
until such stockholder approval required under Section 162(m) of the Code has 
been obtained.

Options may be granted prior to the date of such stockholder approval made 
subject to stockholder approval.  In such event and prior to such grant, the 
Committee shall consult with the Company's accountants as to the accounting 
implications thereof and, if Incentive Stock Options are to be granted, the 
Company's legal counsel as to the requirements for such grants.
