                               PROSPECTUS SUMMARY

   The  following  summary is qualified  in its  entirety by  reference  to, and
should be read in conjunction with, the more detailed  information and financial
statements, including the notes thereto, appearing elsewhere in this Prospectus.
Unless  otherwise  indicated,  the  information in the Prospectus  does not give
effect to the exercise of the Over-allotment Option granted to the Underwriters,
as  described  under  "Underwriting."  On May 31,  1996,  the Company  exchanged
3,000,000  shares of its  Common  Stock for all of the  membership  interest  in
Houston  Enterprises,  L.L.C., an Arizona limited liability company ("Houston"),
and the  financial  statements  at May 31, 1996 reflect that  exchange.  For the
years  ended May 31, 1995 and 1996,  the  Company's  predecessor  was taxed as a
limited liability company.  For income tax reporting  purposes,  all profits and
losses for such  years,  and certain  other  items,  were passed  through to the
members of Houston.  Because the income of the Company will be taxable after May
31, 1996 certain temporary  differences  between financial and tax reporting are
reflected  as an income  tax  benefit in the  statement  of income for the years
reported  and as  deferred  tax  assets  in the  balance  sheets  for the  years
reported.  Except for  historical  information,  the matters  discussed  in this
Prospectus are  forward-looking  and involve risks and uncertainties.  See "Risk
Factors."

                                   THE COMPANY

   M.D. Labs, Inc.  (together with its  subsidiaries,  the "Company")  packages,
markets  and  distributes  natural  food  and  dietary  supplements,  consisting
primarily of herbal products and sports nutrition products,  as well as a weight
management  chewing  gum  product.  The  Company  has  focused  on  new  product
innovation,  such as its Daily  Detox(R)  teas  targeted  to the  detoxification
herbal tea market and its Citrium(TM)  Lean and Trim chewing gum targeted to the
weight loss chewing gum market.  The  Company's  products  generally are sold to
distributors and to health food, drug and other retail stores.

   The Company currently markets the Naturally Klean(R), Daily Detox(R), Women's
Nature(TM),   HerbalPathic(TM)   and  Citrium(TM)  product  lines.  Through  its
wholly-owned subsidiary, Belnik Investment Group, Inc. doing business as Freedom
Wholesalers,  Inc.  ("Freedom"),  the Company  also  markets The  Stuff(TM)  and
Naturally  Klean(R) Herbal  Tea,(TM) and under the  PRO-LINE(R)  name it markets
products such as Super  ProLean(TM)  Fat Burners,  Amino Formula  "1240"(TM) and
Chromoplex(TM).  The Naturally  Klean(R) and Daily Detox(R) lines are focused on
the detoxification  market.  These products are available in teas,  capsules and
extracts.  Women's  Nature(TM) herbal tea and the  HerbalPathic(TM)  single herb
supplements  support and enhance  overall health.  The Citrium(TM)  product line
addresses the weight  management  market.  The Freedom products are intended for
the detoxification and energy supplement markets,  and the PRO-LINE(R)  products
are formulated for the sports nutrition market.

   Sales of herb-based products, including dietary supplements, are estimated to
exceed $1 billion in the United States annually.  Industry sources also indicate
that sales of sports nutrition products,  excluding beverages, were $675 million
in 1995.  The market for natural  dietary  supplements,  weight  management  and
sports nutrition products is highly fragmented,  with intense  competition among
larger  companies  offering  full lines of products and smaller  single  product
companies.  The industry is characterized by frequent new product introductions,
short product life cycles,  rapid price declines and eroding profit margins. The
Company   believes  that  the   competitive   forces  within  the  industry  are
characterized by product innovation,  brand recognition, and effective marketing
and distribution.

   The  Company is  pursuing a  three-pronged  growth  strategy  focusing on (i)
expansion  of sales of  existing  products  to  current  and new  customers  via
increased  advertising and marketing and  development of additional  channels of
distribution;  (ii)  development of new products which  complement the Company's
existing product lines or address new markets with significant growth potential;
and (iii) acquisition of other companies, products or product lines which, as in
the case of new products  under internal  development,  complement the Company's
existing product lines or address new markets with significant growth potential.

   The  Company  was  incorporated  in  Delaware  on  February 7, 1996 to be the
successor  to  Houston.  On  May  31,  1996,  the  Company  acquired  all of the
membership  interests in Houston and thereupon  succeeded to Houston's business.
Houston acquired its original line of products from Houston  Enterprises,  Inc.,
an Arizona  corporation,  through an asset purchase  completed in February 1994.
Houston Enterprises, Inc. introduced its first product line in 1987. In February
1996,  the  Company  purchased  all of the  outstanding  stock of an  affiliated
company,   Belnik  Investment  Group,  Inc.,  an  Arizona   corporation,   which
distributed  the  Freedom  products.  See  "Certain  Transactions."  The Company
obtained the PRO-LINE(R)  product line through the purchase of substantially all
of the assets of Olympian Global,  L.L.C.,  an Arizona limited liability company
("Olympian Global") in January 1996.

   The principal office of the Company is located at 1719 W.  University,  Suite
187, Tempe, Arizona 85281. The Company's telephone number is (602) 437-0127.

(1) For the two years ended May 31, 1996, Houston elected under Internal Revenue
    Code  Sub-Chapter  K to be  treated  as a  limited  liability  company,  and
    accordingly,  generally  was not subject to federal and state income  taxes.
    For income tax reporting  purposes for these years,  all profits and losses,
    and certain  other  items,  were  passed  through to the members of Houston.
    Since the income of the Company will be taxable  after May 31, 1996,  income
    tax expense for the years ended May 31, 1996 and 1995 has been  presented as
    if the  Company  was a C  corporation  during  those  years.  The income tax
    expense was calculated assuming an effective tax rate of 40%.

(2) Based on  weighted  average  common  shares  and  common  share  equivalents
    outstanding as of May 31, 1996, giving  retroactive  effect to the Company's
    conversion in May 1996 from a limited  liability  company to a  corporation,
    and the conversion of membership interests into Common Stock. See Note 14 of
    Notes to Financial Statements.
   
(3) Adjusted  to give  effect to the sale of  1,300,000  shares of Common  Stock
    offered by the  Company  hereby (at an assumed  offering  price of $7.00 per
    share net of  underwriting  discounts and  commissions,  and other estimated
    offering  expenses,  and  exclusive  of  the  Underwriters'   Over-allotment
    Option). See "Use of Proceeds" and "Capitalization."

                                  RISK FACTORS

   Prospective  purchasers  of the Common  stock should  carefully  consider the
following risk factors and the other  information  contained in this  Prospectus
before making an investment in the Common Stock.  Information  contained in this
Prospectus contains "forward-looking  statements" which can be identified by the
use of forward-looking terminology such as "believes," "expects," "may," "will,"
"should" or "anticipates" or the negative thereof or other variations thereon or
comparable terminology,  or by discussions of strategy. See, e.g., "Management's
Discussion and Analysis of Financial  Condition and Results of  Operations"  and
"Business  --  Strategy."  No  assurance  can be given that the  future  results
covered  by the  forward-looking  statements  will be  achieved.  The  following
matters  constitute  cautionary  statements  identifying  important factors with
respect  to  such  forward-looking  statements,   including  certain  risks  and
uncertainties,  that could  cause  actual  results to vary  materially  from the
future results covered in such forward- looking statements.  Other factors could
also cause actual results to vary  materially from the future results covered in
such forward-looking statements.

   
   LIMITED INDUSTRY  EXPERIENCE;  RECENT BUSINESS VENTURE.  Although the Company
has been profitable from inception,  management has not had extensive experience
in the natural dietary supplement  business or in the weight management products
business.  Several of the Company's employees,  however, have been active in the
industry  for a number  of years,  although  no  employees  are  health  science
professionals.  The Company was formed in February 1996 and  commenced  business
through its  predecessor in February 1994.  Consequently,  it has only a limited
operating history. It can be expected that future operating results may continue
to be subject to many of the problems,  expenses,  delays and risks  inherent in
the early  development  of a business  enterprise  and that the Company may have
little control over some of such occurrences.  For example,  the Company has not
completed  the  process of updating  formal  government  regulation  compliance,
inventory control and processing and management  information systems, nor has it
yet received governmental inspections,  such as those conducted by entities such
as the Occupational Safety and Health Administration ("OSHA"), the Food and Drug
Administration  ("FDA") and Federal Trade Commission ("FTC"), as can be expected
in the industry. There can be no assurance,  therefore, that the Company will be
able to continue the development of its business while sustaining  profitability
in future periods. See "Business -- Strategy" and "-- Government Regulation."
    

   SHORT  PRODUCT  LIFE  CYCLES;  DEPENDENCE  ON NEW  PRODUCTS.  Certain  of the
Company's  products  primarily  are used by consumers who are early to adopt new
products.  The markets for such  products are  characterized  by factors such as
changing  customer  demand,  short  product life cycles and frequent new product
introductions.  Such changes and cycles often are not due to identifiable market
factors.  The performance of the Company will depend on its ability  continually
to develop and market new products that achieve customer acceptance and loyalty,
as well as its ability to adapt its product  offerings to meet changing  pricing
considerations,  consumer  preferences and other market  factors.  The Company's
business,  financial  condition  and results of  operations  could be materially
adversely  affected  if the  Company  were to incur  delays  in  developing  new
products  or if such new  products  did not gain market  acceptance.  Therefore,
there can be no assurance that the Company's existing or future products will be
sufficiently  successful  to enable the  Company to compete  effectively  in its
current markets or, should the Company's product offerings meet with significant
customer  acceptance,  that one or more current or future  competitors  will not
introduce products which compete  successfully with the Company's products.  See
"Business -- Product Planning, Development and Acquisition."

   
   COMPETITION AND LOW BARRIERS TO ENTRY. The market for health food supplements
and sports nutrition  products is characterized by intense  competition based on
factors such as product  innovation,  brand recognition and effective  marketing
and distribution.  The Company faces  substantial  competition in its efforts to
capture a  significant  share of its markets.  A number of  companies  currently
offer competing products and additional competing products most probably will be
introduced  by other  companies in the future.  There can be no  assurance  that
other  companies will not develop  products that are similar to those offered by
the  Company.  In  addition,  many  of  the  Company's  existing  and  potential
competitors have greater financial, marketing and research capabilities than the
Company.  Therefore,  these  competitors  may be better  positioned  to  capture
incremental  sales of products  comparable to the Company's  products  which may
become accepted in the mainstream marketplace. See "Business -- Competition."
    
                                        5
<PAGE>
   ABSENCE OF CLINICAL STUDIES,  SCIENTIFIC REVIEW AND TESTING.  As discussed in
greater  detail in the section  relating to government  regulation,  current law
requires the Company to obtain scientific data and substantiation to support its
promotional  claims  concerning its products.  Some products may require advance
FDA approval for the claims,  and all product claims must be at least  supported
by adequate substantiation.  The Company has implemented a policy for collecting
the  available  substantiation  for its  product  claims,  which  in most  cases
consists of information prepared and supplied by other companies,  including the
Company's  suppliers.  The sufficiency of the Company's  substantiation  for its
product claims has not been reviewed by any regulatory  agency,  and the Company
has not provided nor been requested to provide any scientific data to the FDA or
the FTC.  There can be no assurance  that the  substantiation  data  obtained or
available  to the  Company  in  support  of its  product  claims  will be deemed
acceptable  by  the  FDA  or  the  FTC,   should  either  agency   request  such
substantiation  in  the  future.   Further,   the  FTC  has  recently  commenced
administrative proceedings against other businesses in the health food industry,
questioning the sufficiency of their  substantiation for various product claims.
There is no assurance  that such  proceedings  by the FTC or the FDA will not be
brought against the Company,  and such  proceedings or product changes needed to
avoid the commencement of such proceedings  could have a material adverse effect
on the Company's business, financial condition and results of operations.

   
   The  Company  markets its  products on the premise  that they fall within the
category known as "dietary supplements." Current regulations do not require that
this category of products undergo clinical testing or FDA review before they are
marketed.  The Company  does not conduct or sponsor  such  studies,  nor does it
analyze the contents of products  received from third-party  manufacturers.  See
"Risk Factors -- Reliance on Outside Suppliers and  Manufacturers." As a result,
there  can be no  assurance  that the  Company's  products  contain  ingredients
precisely as labelled,  and there is increased risk that the Company's  products
may cause  unexpected  side  effects  for which the Company may be liable to the
persons injured and/or the Company may be subject to administrative and judicial
proceedings  by  the  regulatory  authorities.   Ingredients  similar  to  those
contained  in the  Company's  products  have been  associated  with such adverse
effects.  Additionally,  the Company has  received  occasional  complaints  from
consumers of Daily Detox(R),  Daily Detox(R) II and Naturally  Klean(R) products
regarding  dissatisfaction  with product quality or suggesting a connection with
minor physical ailments, or, in one case, a customer's hospitalization. With the
exception of the  hospitalization  complaint,  the Company has  responded to the
complaining   customers  and  has  resolved  their  complaints  by  providing  a
replacement  or similar  product  of the  Company.  In the case of the  reported
hospitalization,  although the Company believes the complaint is meritless,  the
Company has tendered the complaint to its product liability  insurance  carrier.
The Company has never been served with a product liability lawsuit.  Because the
Company is highly dependent upon consumers' perception of the safety and quality
of its products as well as similar products distributed by other companies,  the
Company's  business,  financial  condition  and results of  operations  could be
materially  adversely  affected if any of the Company's  products or any similar
products distributed by other companies should prove to be harmful to consumers.
In addition,  because of the Company's  dependence  upon  consumer  perceptions,
adverse  publicity  associated with illness or other adverse  effects  resulting
from  consumers'  failure to consume the Company's  products as suggested by the
Company  or other  misuse  or abuse of the  Company's  products  or any  similar
products  distributed by other companies could have a material adverse effect on
the Company's business, financial condition and results of operations.
    
   Further,   the  Company  believes  that  recent  growth  experienced  by  the
nutritional  supplement  market  is based in part on  national  media  attention
regarding recent scientific research  suggesting  potential health benefits from
regular  consumption  of certain  nutritional  products.  Such research has been
described  in major  medical  journals,  magazines,  newspapers  and  television
programs.  The scientific  research to date is preliminary,  and there can be no
assurance of future favorable  scientific  results and media attention or of the
absence of unfavorable  or  inconsistent  findings.  See "Business -- Government
Regulation."  There is also no assurance that regulatory  agencies will continue
to  permit  the  marketing  of such  products  based on the  type of  scientific
research available.

   Some of the  Company's  products  may not qualify  for  dietary  supplemental
status,  and may become the subject of regulatory  classification as a "drug" or
"new  drug." The  absence of clinical  studies  and  scientific  review for such
products could require the Company to discontinue their sale until formal FDA
                                        6
<PAGE>
   
approval of a New Drug Application is obtained. The Company does not expect that
it would be in a position to finance the  submission of a New Drug  Application.
At  present  all of the  Company's  products  are of a type  which are  commonly
marketed by various companies as dietary supplements,  and not as "drugs". There
is no assurance as to any of the Company's products that a "drug classification"
might not be imposed. For example, the Company's Naturally Clean(R) product line
consists of products designed to stimulate the body's natural cleansing process.
Such  products  are  today  sold  by  various  companies  as  foods  or  dietary
supplements.  If, by administrative or legislative action,  products making such
claims were to be classified as "drugs,"  these products might no longer be able
to be sold with such claims. In the event that a drug  classification is imposed
for any of the claims for which the  Company  markets  its  products,  it is the
Company's  intention  to remove such claims  from its product  labels.  This may
adversely  affect the Company's  ability to promote such  products.  The Company
cannot  anticipate  which of its  products  might be affected by such changes in
classification.
    

   All or any of the above may require  the Company to make a business  decision
to  discontinue  the  marketing  of one or more  of its  products.  There  is no
assurance  that  any  such  discontinuance  or the  cumulative  effect  of  such
discontinuance may not have a material adverse effect on the Company's business,
financial condition or results of operations.

   UNCERTAINTY AND POTENTIAL  NEGATIVE  EFFECTS OF GOVERNMENT  REGULATIONS.  The
manufacturing,  processing, formulating, packaging, labelling and advertising of
the  Company's  products  are  subject  to  regulation  by one or  more  federal
agencies,  including the FDA, the FTC, the Consumer  Product  Safety  Commission
(the "CPSC"),  the United States Department of Agriculture (the "USDA"), and the
Environmental  Protection Agency (the "EPA"). The Company's  activities are also
regulated by various agencies of the states, localities and foreign countries to
which the Company's products are distributed and in which the Company's products
are sold.

   The  composition  and  labelling  of dietary  supplements,  which  comprise a
significant  majority of the Company's  products,  is most actively regulated by
the FDA under the provisions of the Federal Food,  Drug, and Cosmetic Act ("FFDC
Act").  The FFDC Act has been revised in recent years by the Nutrition  Labeling
and  Education  Act of 1990  ("NLEA") and by the Dietary  Supplement  Health and
Education  Act of 1994  ("DSHEA").  While in the  judgment of the Company  these
regulatory changes are generally favorable to the dietary supplements  industry,
there can be no assurance  that the Company will not in the future be subject to
additional laws or regulations  administered by various regulatory  authorities.
In addition,  there can be no assurance that existing laws and regulations  will
not be repealed or be subject to more stringent or unfavorable interpretation by
applicable regulatory authorities.

   The  labelling  requirements  for dietary  supplements  have not been clearly
established. In December 1995, the FDA issued proposed regulations to govern the
labelling of dietary supplements. These regulations are expected to become final
later in 1996,  and would  require  the  Company  to revise  all of its  dietary
supplement labels in 1997. The FDA has informally  stated that it will,  subject
to public comment,  withhold  enforcement of these  regulations until January 1,
1998.

   
   Marketing  and sale of dietary  supplements  is to some extent  dependent  on
avoiding a drug classification for such products. The FDA has not yet delineated
how the drug versus dietary  supplement  distinctions will be made under the new
law. Some of the Company's products may be regulated separately as foods without
invoking  the  provisions  of the law  applicable  to dietary  supplements.  The
adoption of new regulations in the United States or elsewhere, or changes in the
interpretation of existing regulations,  could have a material adverse effect on
the Company's business, financial condition and results of operations.

   In February and April of 1996,  the Company was advised by the offices of the
district attorney of Sonoma County and Napa County, California of certain issues
regarding  the label and  advertising  promotion  claims made for the  Company's
citrium and super  prolean  products.  These  counties  requested the Company to
provide  substantiation  for the  efficacy  claims made on the labels and in the
advertising for these products.  Through correspondence with these counties, the
Company has submitted its  substantiation  for the claims.  The County of Sonoma
also questioned the Company's use of the word "natural" for these products,  and
the Company responded by indicating that this use was consistent with current
    
                                        7
<PAGE>
   
industry  practice.  The last  correspondence  with these counties was in May of
1996,  and the Company has not heard further from these  counties in response to
the  substantiation  submitted.  See also  "Business --  Government  Regulation"
regarding  substantiation  requirements.  The Company  has also been  advised by
several  states,  including  the  State  of New  York,  that it may not sell its
Naturally  High(TM)  herbal energy product or any other product that contains ma
huang or ephedrine in that state. The Company has discontinued selling Naturally
High(TM), the only product of the Company which contained ma huang or ephedrine.
    

   The  Company  cannot   predict  the  nature  of  future  laws,   regulations,
interpretations  or  applications,  nor  can it  determine  what  effect  either
additional  governmental  regulations  or  administrative  orders,  when  and if
promulgated,  or disparate  federal,  state and local regulatory  pronouncements
would have on its business in the future. Applicable regulations could, however,
require the  reformulation of certain products to meet new standards,  recall or
discontinuance  of  certain  products  not able to be  reformulated,  additional
recordkeeping,  expanded  documentation  of the properties of certain  products,
expanded or different labeling and/or scientific  substantiation.  Any or all of
such  requirements  could  have a  material  adverse  effect  on  the  Company's
business, financial condition and results of operations.

   
   Governmental  regulations in foreign countries may also apply to sales of the
Company's products sold in these countries. The Company's international sales to
date have been primarily through  distributors  serving Japan,  Taiwan,  Canada,
Korea and Bermuda.  The Company relies on its independent  distributors in these
countries for  compliance  with foreign  regulations.  For example,  the Company
altered  the  formulation  of its  Citrium(TM)  gum for sale in Japan based upon
input from its  distributors  regarding  Japanese law.  These  distributors  are
independent  contractors over whom the Company has limited control. There can be
no  assurance  that the sales of the  Company's  products  comply  with  foreign
regulations  or will  continue to do so in the future.  In the event of any such
failure,  the Company may be subject to penalties for such non-compliance  which
would  have a  material  adverse  effect on the  Company's  business,  financial
condition and results of operations.  Additionally,  Governmental regulations in
foreign  countries  where the  Company  plans to  commence  or expand  sales may
prevent or delay entry into the market or prevent or delay the introduction,  or
require the reformulation of certain of the Company's products. See "Business --
Government Regulation."

   NON-COMPLIANCE WITH GOVERNMENT REGULATIONS.  The Company's business is in the
industry commonly known as the "health food industry" which has been the subject
of many years of vigorous  administrative  and judicial  enforcement by the FDA.
The FDA has taken the position that many  businesses  which  conduct  operations
similar to those of the Company are to varying  extents in violation of the law.
The Company has recently undertaken a review of its products in light of current
regulations.  Because of the evolving  status of the regulatory  environment and
the early stage in the life cycle of many of the Company's products, the Company
cannot be certain as to which regulations  govern its activities.  Nevertheless,
the  Company  believes  that some of its  products do not or may not comply with
existing  regulations  in all  respects.  The Company has  commenced  making the
modifications  that it believes are necessary to come into  material  compliance
with such regulations.  These  modifications  will apply to all of the Company's
products,  and will include revised labeling to incorporate necessary statements
and disclosures  (identification of product as a "dietary supplement" and, where
applicable,  adding a notice that "This statement  [about an efficacy claim] has
not been  evaluated  by the Food and Drug  Administration.  This  product is not
intended to diagnose,  treat,  cure, or prevent any disease." After the labeling
changes are made,  the Company will also provide  formal  notice to the FDA that
such  statements  have been  placed on the label of a  product.  As part of this
process,  the Company will also generally review its product line for compliance
with  technical  requirements  such as type size,  sufficiency of declaration of
ingredients,  as well as for the sufficiency of  substantiation  for any product
claims.  The Company estimates that the cost of making the label changes will be
approximately  $35,000.  The Company expects that it will be able to comply with
the  modifications  needed for the labels,  but there is no  assurance  that the
Company's  substantiation,  for any particular claim will be adequate to support
the  continued  marketing of products  with such claim.  A  requirement  for the
removal of "unsubstantiated  claims" from the Company's labeling and advertising
could have a material adverse effect on the Company. See "Business -- Government
Regulation" regarding substantiation requirements. 
    
                                        8
<PAGE>
   The Company's  facilities  are subject to regulation by various  governmental
agencies,  including state and local licensing,  zoning, land use,  construction
and environmental  regulations and various health,  sanitation,  safety and fire
codes and  standards.  Failure to obtain  necessary  licenses  or  approvals  or
suspension,  due to failure to comply with applicable  regulations or otherwise,
could interrupt the Company's packaging and distribution operations. The Company
recently  became aware of the need for local  licensing  with respect to certain
aspects  of its  business.  The  Company  may be subject  to  criminal  or civil
penalties,  including  orders or  injunctions  to cease certain  operations  for
failure to have such  licensing.  There can be no assurance that the Company can
obtain such licensing without incurring  material  disruption of its business or
material regulatory penalties, if at all.

   
   EFFECT OF DISCONTINUED PRODUCT. The Company recently discontinued selling its
Naturally High(TM) herbal energy product.  Naturally  High(TM)  represented less
than 1% of revenues in fiscal 1996. This product contains ma huang. Ma huang has
been the subject of certain  adverse  publicity  in the United  States and other
countries relating to alleged harmful effects. After numerous reports of adverse
reactions,  the FDA has warned  that  people  should not  consume ma huang,  and
several states and local governments have banned or heavily  regulated  products
containing  ma  huang.  The  FDA  has  investigated   reports  linking  products
containing ma huang or its active  ingredient,  ephedrine,  to adverse reactions
such as heart problems,  stroke and death. The State of New York banned the sale
and distribution of Naturally High(TM) and 19 competitors'  products due to this
reported link of products containing ephedrine to adverse reactions. In general,
there has been very vigorous  regulatory  activity at both the federal and state
level against  products  which might be construed as a substitute  for otherwise
illegal  street drugs.  Also, on May 23, 1996 Bill Number S.1806 was  introduced
into the United States Senate, which would amend the FDDC Act to provide that if
the label or labeling of a dietary supplement claims or implies that it produces
euphoria,  heightened  awareness,  or similar mental or psychological effects --
such a product  would be regulated  as a drug under the Act. See the  discussion
above regarding significance of drug classification.

   While the  Company  believes  that  Naturally  High(TM)  is safe when used as
suggested and the Company does not know of any heart problems,  strokes,  deaths
or other  health-related  incidents that have been linked to the product, it has
chosen to focus on other products. In August 1996, the Company received a letter
from the FDA, which referred to the recent  regulatory  activity  concerning the
above types of products,  and specifically  objected to the Company's  continued
marketing of Naturally High.(TM) On August 30, 1996, the Company advised the FDA
that the Company had discontinued  the sale of Naturally  High(TM) and would not
market  any  other  products  which  contained  ma  huang or any  other  type of
ephedrine.
    

   The Company has not received any claims of liability with respect to products
containing ma huang  previously  sold by the Company,  although  there can be no
assurance that such claims will not be asserted in the future.  See "Business --
Products," "-- Product Liability" and "-- Government Regulation."

   PRODUCT CONCENTRATION.  Sales of the Company's Naturally Klean(R) and related
products,  and Citrium(TM)  products  accounted for  approximately  51% and 25%,
respectively, of the Company's net sales for the fiscal year ended May 31, 1996.
The Company  anticipates  the sale of such products or a limited number of other
products will continue to contribute a substantial  portion of total revenues in
subsequent  periods.  The market for the Company's  products is characterized by
extensive competition,  frequent new product  introductions,  short product life
cycles, rapid product declines,  eroding profit margins and changing preferences
of  consumers.  A  decline  in the  demand  for any of the  Company's  products,
including  the  foregoing,  whether  as a  result  of  competition,  changes  in
demographic trends or other factors, could have a material adverse effect on the
Company's business, financial condition and results of operations. See "Business
- -- Products."

   
   DIFFICULTY OF PRODUCT POSITIONING.  Approximately 55% of the Company's fiscal
1996 revenue was derived from sales of The  Stuff(TM)  and  Naturally  Klean(R).
These  products  are  designed to  eliminate  temporarily  toxins from the body.
However, the Company believes the products instead are often used in preparation
for urine drug testing. A change in drug testing methodology from urine tests to
blood or hair tests  could cause a material  decrease in sales of The  Stuff(TM)
and Naturally Klean(R) and, therefore, in
    
                                        9
<PAGE>
revenues  and profits for the Company.  Additionally,  there can be no assurance
that the potential  association by customers of the Company with such activities
would not  hinder  market  acceptance  of the  Company's  other  products  as it
attempts to replace any lost revenues from such a change in methodology or seeks
to diversify its product offerings. See "Business -- Products."

   
   EXPOSURE  TO PRODUCT  LIABILITY.  The  Company  faces a  significant  risk of
product liability claims in the event that the use of its products is alleged to
have resulted in adverse health effects.  To date, no product liability lawsuits
have been  brought  against  the  Company.  However,  a number of the  Company's
competitors  are  routinely  sued on product  liability  claims.  Moreover,  the
Company's products contain  ingredients,  although in different  combinations or
concentrations, which have been associated with adverse effects. The Company has
purchased product and general liability  insurance with general aggregate limits
of $2 million and a $3 million excess liability  umbrella policy.  Such policies
provide  coverage  of up to $1  million  for each  occurrence.  There  can be no
assurance  that  liability  claims  will not  exceed the  coverage  limits or be
excluded by coverage  limitations  or that such  insurance  will  continue to be
available on commercially reasonable terms or at all. If the Company does not or
cannot  maintain  sufficient  liability  insurance,  its  ability  to market its
products may be significantly  impaired.  In addition,  product liability claims
could  have a  material  adverse  effect on the  Company's  business,  financial
condition and results of operations. See "Business -- Product Liability."

   LIMITED  CAPITALIZATION.  After completion of this Offering, the Company will
have approximately  $9.58 million in working capital.  There can be no assurance
that  such  capitalization  is  sufficient  to enable  the  Company  to  compete
adequately  in the  industry on a continual  basis or to defend  itself  against
potential liabilities  associated with its products.  Additionally,  the Company
plans to continue to grow  through  development  of its  existing  products  and
through the development  and acquisition of new products and existing  operating
companies.  The planned development and expansion of the Company's business will
place  significant  demands on the Company's  working  capital.  There can be no
assurance that sufficient capital resources would be available to the Company if
and when  required by  management,  or on terms that would be  acceptable to the
Company.  In the course of raising such additional  capital,  the Company may be
required to forego a substantial  interest in its future  revenues or dilute the
equity interests of existing stockholders, and a change in control could result.
See "Risk  Factors --  Competition  and Low  Barriers to Entry," "-- Exposure to
Product  Liability,"  "Selected  Financial  Data" and "Business -- General," "--
Strategy" and "-- Competition." 
    

   CUSTOMER CONCENTRATION. Over 50% of the Company's revenues are generated from
sales to distributors  and large retail accounts,  including one account,  Naoki
Corporation of Japan ("Naoki"),  which  constituted  $634,000,  or approximately
12.2% of the Company's net sales in fiscal year ended May 31, 1996.  The Company
does not have written  contracts  with its primary  distributors.  Additionally,
seven customers  comprised  approximately 60% of the accounts receivable balance
at May 31, 1996. Although there can be no assurance that the Company's principal
customers will continue to purchase products from the Company at current levels,
if at all, the Company expects to continue to depend on its principal  customers
for a  significant  portion  of its  net  sales.  The  loss  of any  one of such
customers  could  have a  material  adverse  effect on the  Company's  business,
financial condition and results of operations. See "Business -- Marketing."

   
   RELIANCE ON OUTSIDE  SUPPLIERS  AND  MANUFACTURERS.  The Company  relies upon
various  outside  sources to supply its raw  materials  and to  manufacture  its
products, many of which obtain raw materials from outside the United States. The
Company has not determined if the outside  manufacturers  comply with applicable
regulations or licensing  requirements or if the foreign  jurisdictions  provide
the Company recourse for manufacturing defects. The Company does not analyze the
contents of products  received  from  outside  suppliers or  manufacturers.  The
Company currently has no written  agreements with any of such sources;  however,
the  Company's  relationships  with  these  sources  are  believed  to be  good.
Nevertheless,   any  disruption  in  the  supply  of  raw   materials,   in  the
manufacturing  volume or delivery schedule,  in the pricing or in the quality of
such products is outside of the Company's direct control and could adversely and
materially  affect the Company's  business,  financial  condition and results of
operations until replacement sources are established. In addition, the Company's
recourse against such suppliers for any 
    
                                       10
<PAGE>
damages it may suffer may be limited. Because the industry is characterized by a
fragmented   manufacturing   base,   management   believes  that  other  outside
manufacturing  services  could be  obtained  at  similar  costs from a number of
alternative  sources within a reasonable  period of time,  with the exception of
the source of most of the Company's  herbal  products.  Management  believes the
Company reserves adequate  inventory in the event of a need to change suppliers.
However,  an interruption  in the supply of raw materials,  such as through crop
failures or  embargoes,  could have a material  adverse  effect on the Company's
business,  financial  condition  and results of  operations.  See  "Business  --
Production."

   RELIANCE ON OTHERS TO DEVELOP PRODUCTS.  None of the Company's  employees are
health  science  professionals,  and the Company itself has not developed any of
the products that it currently  sells. To date, it has relied on the acquisition
of product  formulas  through  various  asset  purchases  and the  commission of
product  development with health science  professionals.  At present the Company
pays  royalties  to certain  of the  developers  of the  product  formulas.  See
"Business -- Product  Royalties." The Company does not have long-term  contracts
with any health science  professionals  for the  development of new products and
will continue for the foreseeable future to rely on third parties to develop new
products.  No assurances can be given that such  individuals  will be willing or
able to develop  commercially  successful products for the Company, or that such
individuals'  services or product  formulas  will be available on terms that are
advantageous to the Company. See "Business -- Product Planning,  Development and
Acquisition."

   MANAGEMENT  OF  GROWTH.  The  Company  plans to expand its  overall  level of
operations,  which is expected to strain the  Company's  management,  technical,
financial  and other  resources.  To manage growth  effectively,  the Company is
likely to hire additional personnel, implement expanded operating, manufacturing
and financial  controls,  install enhanced reporting and management  information
systems for  materials  procurement,  manufacturing,  order  processing,  system
monitoring,  customer service and financial reporting,  and otherwise to improve
coordination between product formulation,  manufacturing  processes,  marketing,
sales and finance functions.  The Company's failure to expand its sales base and
manage growth  effectively could have a material adverse effect on the Company's
business,  financial  condition  and results of  operations.  See  "Business  --
Strategy."

   SELECTION AND  INTEGRATION  OF  ACQUISITIONS.  A key element of the Company's
strategy is expansion  through the  acquisition  of other  companies,  assets or
product  lines.  There can be no  assurance,  however,  that the Company will be
successful in identifying  appropriate  opportunities  or negotiating  favorable
terms.  The  integration  of any such  acquisition  is  critical  to the  future
financial  performance  of the  Company  after  any such  acquisition.  Complete
integration of any  acquisitions  could take several  quarters to accomplish and
will  require,  among other things,  integration  of the  companies'  respective
product offerings and coordination of their sales and marketing,  manufacturing,
research and development and regulatory  compliance  efforts.  The difficulty of
combining  companies may be increased by the need to integrate the personnel and
geographic  distance  between  the  companies.  Changes  brought  about  by  any
acquisition   may  cause  key  employees  or  distributors  to  terminate  their
relationship with the Company. In addition,  the Company might incur significant
integration or additional operating costs associated with an acquisition.  There
can be no  assurance  that such costs will not have an adverse  effect  upon the
Company's business, financial condition and results of operations,  particularly
in  the  fiscal  quarters   immediately   following  the   consummation  of  any
acquisition,  while the operations of the acquired business are being integrated
into the Company's  operations.  The process of integrating  companies may cause
management's  attention to be diverted from operating the Company.  In addition,
the process of combining two organizations could cause the interruption of, or a
loss of  momentum  in,  the  activities  of  either  or  both of the  companies'
businesses.  There can be no assurance that any acquisition  will not materially
and adversely affect the Company's  business,  financial condition or results of
operations or that any such acquisition will enhance the Company's business.
See "Business -- Strategy."

   
   DEPENDENCE  ON MANAGEMENT  AND KEY  PERSONNEL.  The Company  depends upon the
active involvement of its senior managers, including its executive officers. The
loss of one or more of such officers could have a material adverse effect on the
Company's  business,  financial  condition and results of operations.  While the
Company has not purchased key man insurance on any of its key personnel,  it has
entered into
    
                                       11
<PAGE>
   
employment agreements with Messrs.  Nikzad, Todd Belfer,  Djahandideh and Denton
as executive officers. Two of the Company's directors, Harvey Belfer, the father
of Todd Belfer,  and Kenneth A. Steel,  serve as consultants to the Company on a
part-time  basis.  They have  committed to the Company that they will make their
time available to the Company as its business may require.  Although the Company
believes that these directors' time commitments should be sufficient to meet the
demands of the business of the Company, there is no assurance they will continue
to have  sufficient  time  available  or that the  Company  will be able to hire
additional  managers  with  the  necessary  expertise  if the need  arises.  The
Company's  success and growth strategy also depend on its ability to attract and
retain qualified finance,  accounting,  purchasing,  marketing,  sales and other
personnel.  Such personnel are in high demand and are often subject to competing
offers.  There can be no assurance  that the Company will be able to attract and
retain the qualified  personnel  necessary for its business and planned  growth.
See "Business -- Production" and "Management -- Employment Agreements."

   UNCERTAINTY  REGARDING  PROPRIETARY RIGHTS. The Company's success will depend
in  significant  part on its  ability to retain  protection  of its  proprietary
rights,  including  preservation  of its trade  secrets  and  know-how,  without
infringing  on the rights of others.  The  Company's  products  are sold under a
variety of trademarks  and trade names.  While the Company  believes that it has
valid proprietary  interests in all currently used trademarks and trade names in
the United States, only certain of the trademarks have been granted registration
with the United States Patent and Trademark Office ("U.S.  Pat.  Off."),  others
have  been  filed  with the  U.S.  Pat.  Off.  and are in the  process  of being
registered,  and others have not been filed.  Additionally,  the Company entered
into an agreement  with Olympian  Global in January 1996 for the  acquisition of
rights to the federally-registered  trademark,  PRO-LINE(R),  as well as certain
related names and marks. The Company believes  Olympian Global may have breached
certain aspects of the acquisition agreement relating to the trademark and trade
name rights transferred thereunder.  The Company is unable to predict the extent
(if any) to which its  rights to the  assigned  trademark  and trade name may be
affected by this matter. See "Business  Products -- Sports Nutrition  Products."
There can be no assurance that the Company will be able to  successfully  defend
its  trademarks  or trade  names  against  claims that might be brought by third
parties  or  obtain  protection  for  trademarks  or trade  names  used with new
products.  See "Business --  Proprietary  Rights:  Trade Names,  Trademarks  and
Copyrights."
    

   The  Company  does  not  maintain  patent  protection  for its  products  and
processes,  but rather  relies on trade  secret laws and common law  concepts of
confidentiality to protect its product  formulations.  There can be no assurance
that the measures  taken by the Company will protect the  Company's  proprietary
information  or that others will not gain  access to, or  independently  develop
similar trade secrets or know-how which will permit them to develop formulations
or processes that are substantially similar or superior to those of the Company.

   ACCOUNTS  RECEIVABLE.  The Company distributes its products primarily through
distributors and retailers.  While the Company  typically  extends 30-day credit
terms to qualified  customers,  some of its  distributors  and retailers tend to
extend the payment of their  accounts  beyond such terms and some are  requiring
longer payment terms. For the year ended May 31, 1996, the Company's  receivable
turnover was approximately 44 days. Although the Company has experienced no cash
flow  problems in the past caused by the aging of its  accounts  receivable,  as
management implements its plans for growth and should revenues rise, the Company
may  experience  larger  accounts   receivable   balances  and  increasing  cash
requirements,  possibly  creating  cash flow  pressures.  Such  pressures  could
present difficult working capital demands on the Company which, if not resolved,
could limit the Company's growth. See "Business -Marketing."

   FLUCTUATIONS IN OPERATING RESULTS.  The Company's  operating results may vary
significantly due to a variety of factors, including changing market demands and
customer  demographics,   the  availability  and  cost  of  raw  materials,  the
introduction of new products by the Company and its competitors,  seasonality of
sales, the ability of the Company's sub-contractors and manufacturers to perform
as  agreed,  the timing  and  effectiveness  of the  Company's  advertising  and
promotional  campaigns,   pricing  pressures,   general  economic  and  industry
conditions  that  affect  customer  demand  and other  factors.  There can be no
assurance  that the Company can  continue to operate at historic  levels or that
the Company's financial performance will remain stable from  quarter-to-quarter.
The Company expects quarterly operating results
                                       12
<PAGE>
to vary in the future.  Accordingly,  period-to-period  comparisons of financial
results  should not be relied upon as an  indication of future  performance.  No
assurance  can be given that the Company  will  maintain  profitability,  in any
given quarter,  or at all, in the future.  It is possible that, if the Company's
stock is followed by market analysts, the Company's results for any quarter will
fall below such analysts' expectations. In such event, the market for the Common
Stock would be materially adversely affected.

   NO INDEPENDENT MARKET STUDIES.  The Company participates in markets for which
there generally is limited available market data. The Company has formulated its
business  strategies  based on certain  assumptions of the Company's  management
regarding  the  size of its  markets,  the  Company's  anticipated  share of the
markets,  and the estimated prices for and acceptance of the Company's products.
There can be no assurance that these  assessments  will prove to be correct.  No
independent market studies have been conducted on behalf of the Company, nor are
such studies planned. See "Business -Marketing."

   RISK OF PRODUCT RETURNS.  The Company  encounters the risk of product returns
from its customers.  The Company's  current  return policy for retail  customers
generally  involves  exchange  of  products  and not the refund of the  purchase
price.  Nevertheless,  certain of the Company's  larger  customers are requiring
more  favorable  return  policies  including  longer  periods  within which such
customers may return  products for a credit.  Product  returns to date have been
less than 4% of sales; however,  there can be no assurance that actual levels of
returns will not significantly exceed the amounts previously  experienced by the
Company,  and such returns could have a material adverse effect on the Company's
business, financial condition and results of operations.

   
   RISKS  ASSOCIATED  WITH  INTERNATIONAL  SALES.  In fiscal 1996,  distributors
serving  primarily  Japan,  Taiwan,  Canada  and Korea,  and to a lesser  extent
Bermuda,   England,   Israel,  the  West  Indies,  Australia  and  South  Africa
represented  approximately  17% of the  Company's  total  revenues.  The Company
intends to continue to expand its  operations  outside the United  States and to
enter  additional   international   markets,   which  will  require  significant
management  attention  and  financial  resources.  The Company has committed and
continues to commit  significant  time and development  resources to customizing
its products for selected international markets and to developing  international
sales and support channels. There can be no assurance that the Company's efforts
to develop  international sales will be successful.  The failure of such efforts
could  have a  material  adverse  effect on the  Company's  business,  financial
condition and results of operations.
    

   International  sales are  subject to  inherent  risks,  including  unexpected
changes in regulatory requirements, uncertainties with regard to laws protecting
proprietary technology, import and export restrictions and tariffs, difficulties
in staffing and managing  foreign  operations,  the burdens of complying  with a
variety of foreign laws,  greater  difficulty  and delay in accounts  receivable
collection,  potentially  adverse tax  consequences  and  political and economic
instability. The Company's export sales are currently denominated exclusively in
United  States  dollars.  An increase in the value of the United  States  dollar
relative to foreign  currencies could make the Company's products more expensive
and,  therefore,  potentially less  competitive in foreign  markets.  If for any
reason exchange or price controls or other  restrictions  on foreign  currencies
are  imposed,  the  Company's  business,  financial  condition  and  results  of
operations could be materially adversely affected.

   
   NO PRIOR MARKET;  POSSIBLE VOLATILITY OF STOCK PRICE. Prior to this Offering,
there has been no public  market for the Company's  Common  Stock.  Accordingly,
there can be no  assurance  that an active  trading  market  will  develop or be
sustained  upon  completion  of this  Offering  or that the market  price of the
Common  Stock will not decline  below the initial  public  offering  price.  The
trading  price  of the  Common  Stock  could  also  be  subject  to  significant
fluctuations  in  response  to  variations  in  quarterly   operating   results,
developments in the health  supplement  industry,  the FDA and other  regulatory
actions, public concern as to the safety of products developed by the Company or
others, stock market or general economic  conditions,  consumer tastes and other
factors.  The  initial  public  offering  price  of the  Common  Stock  will  be
determined by negotiations among the Company and the Underwriters and may not be
indicative  of  the  prices  that  may  prevail  in  the  public   market.   See
"Underwriting." 
    
                                       13
<PAGE>
   
   DILUTION.  The initial  public  offering  price per share of Common  Stock is
substantially  higher than the net  tangible  book value per share of the Common
Stock.  Purchasers in this Offering will  experience  immediate and  substantial
dilution  of $4.86 Per  share in the net  tangible  book  value per share of the
Common Stock from the initial public offering price. See "Dilution."

   WARRANT TO THE REPRESENTATIVES. In connection with this Offering, the Company
will sell to the  representatives  of the  Underwriters,  for a nominal  cost, a
warrant (the "Representatives'  Warrant") to purchase up to 10% of the number of
shares of Common Stock sold in this Offering. The Representatives'  Warrant will
be exercisable commencing one year after the effective date of this Offering and
for five years thereafter,  at an exercise price of $8.54 per share.  Holders of
the Representatives'  Warrant are given the opportunity to profit from a rise in
the market price of the Common  Stock with a resulting  dilution of the interest
of stockholders. Furthermore, the Company will grant certain registration rights
with regard to the  Representatives'  Warrant and such registration could result
in substantial expense to the Company. See "Underwriting."

   CONTROL BY EXISTING STOCKHOLDERS. Following the sale of the shares offered by
this  Prospectus,  the Company's  existing  stockholders  will  beneficially own
approximately  70.4% of the outstanding Common Stock (67.4% if the Underwriters'
Over-allotment  Option is  exercised  in full) and the  Company's  officers  and
directors  will own  beneficially  in the aggregate  approximately  55.0% of the
Common Stock (52.6% if the Underwriters'  Over-allotment  Option is exercised in
full). Because of such ownership, these stockholders will continue to be able to
influence  the election of members of the  Company's  Board of Directors  and to
control  the  affairs  of the  Company,  including  mergers  or  other  business
combinations. See "Principal Stockholders."

   SHARES ELIGIBLE FOR FUTURE SALE; POTENTIAL FOR ADVERSE EFFECT ON STOCK PRICE.
Sales of substantial  amounts of Common Stock in the public market following the
Offering  could have an adverse  effect on the market price of the Common Stock.
The  1,300,000  shares  offered  hereby,  and any shares  sold  pursuant  to the
exercise  of the  Underwriter's  Over-allotment  Option,  are  freely  tradeable
without restriction. Certain stockholders, including all officers and directors,
holding an aggregate  of 2,324,625  shares of Common Stock have agreed that they
will not sell any Common Stock without the prior  consent of the  representative
of the  Underwriters  (the  "Representative")  for a period of 180 days from the
date of this Prospectus (the "Lockup Period").  All 3,000,000 shares outstanding
prior to this Offering are "restricted securities" and will be eligible for sale
in compliance  with Rule 144 under the  Securities  Act of 1933, as amended (the
"Securities Act"). In general,  Rule 144 permits sales of securities,  beginning
90 days  after the date of this  Prospectus,  by persons  who have  beneficially
owned securities for a requisite holding period, subject to certain restrictions
as to the volume of the  securities  sold,  the  manner of sale,  notice and the
availability of current public information about the Company. Holders of 498,375
shares of Common  Stock and warrants to acquire  257,656  shares of Common Stock
have the right, under certain circumstances,  to require the Company to register
their shares for resale under the  Securities  Act and to  participate in future
Company registrations.  Additionally,  as of October 15, 1996, 268,000 shares of
Common Stock were issuable under options outstanding in the Company's 1996 stock
option plan ("Stock Option Plan"),  none of which were exercisable,  and 578,421
shares of Common Stock were issuable upon the exercise of outstanding  warrants,
of which  267,656 were  exercisable.  Promptly  after  expiration  of the Lockup
Period,  the Company  intends to register all shares reserved for issuance under
its Stock Option Plan. See  "Management -- Stock Option Plan,"  "Description  of
Capital Stock -- Registration Rights," and "Shares Eligible for Future Sale."

   CERTAIN RESTRICTIVE CHARTER AND BYLAW PROVISIONS.  The Company's  Certificate
of Incorporation (the  "Certificate") and Bylaws empower the Board of Directors,
without approval of the  stockholders,  to fix the rights and preferences of and
to issue shares of Preferred  Stock;  prohibit a substantial  stockholder of the
Company from entering  into a business  combination  or otherwise  significantly
increasing  its  interest in the stock or assets of the Company and prohibit the
Company  from  purchasing  assets  or  stock of such a  substantial  stockholder
without the consent of the Board of Directors  or a  two-thirds  majority of the
stockholders  of the Company;  provides for  staggered  terms for the  Company's
directors  and  prohibit  stockholders  of the  Company  from  calling a special
meeting unless requested by at least 25% of the outstanding  voting shares.  The
Certificate  does not provide for  cumulative  voting for  election of directors
    
                                       14
<PAGE>
   
and does require  cause and the vote of a majority of  stockholders  to remove a
director.  The  Company  is  subject to the  provisions  of  Section  203 of the
Delaware General  Corporation Law which, in general,  prohibits the Company from
engaging in certain  business  combinations  with  interested  stockholders  (as
defined in the statute) for a period of three years after the person is named an
interested stockholder unless (with certain exceptions) the transaction in which
the person  became an  interested  stockholder  is approved as prescribed in the
statute.  These  provisions  could  have the  effect  of  deterring  unsolicited
takeovers or other business  combinations  or delaying or preventing  changes in
control  or  management  of  the  Company,   including   transactions  in  which
stockholders   might   otherwise   receive  a  premium  for  their  shares  over
then-current market prices. In addition,  these provisions may limit the ability
of stockholders to approve  transactions  that they may deem to be in their best
interests. See "Description of Capital Stock -Certain Anti-Takeover Provisions."

   MANAGEMENT DISCRETION REGARDING USE OF PROCEEDS.  Approximately $2,525,000 or
33.3% of the net proceeds of the  Offering,  after  deducting  all  underwriting
discounts and  commissions,  and after  deducting all estimated  expenses of the
Offering, and assuming the Underwriters' Over-allotment Option is not exercised,
is committed to specific uses identified in this Prospectus,  with the remainder
available  for  other  corporate  purposes  such as  working  capital  or future
acquisitions.  The Company will have broad  discretion in using the  unallocated
net proceeds of the Offering. Prospective investors will not have an opportunity
to evaluate the relative merits of such unspecified uses. See "Use of Proceeds."

   SUBSTANTIAL  PORTION OF  PROCEEDS  TO BE USED FOR NEW  PRODUCT  INTRODUCTION.
Approximately  $1,625,000, or 21% of the proceeds of this Offering, will be used
by the Company in connection  with the development of sports  nutrition  product
lines.  These  product  lines  are  still  under  development  and have not been
marketed.  Consequently,  the Company does not have any  information  concerning
consumer  acceptance of the product lines. As with all of the Company's existing
product  lines,  the sports  nutrition  market is  extremely  competitive,  with
frequent product introductions.  There can be no assurance that the Company will
complete  development of its planned  product lines or that such planned product
lines  will be  accepted  by  consumers,  will be able to  compete  successfully
against other similar products, or will be commercially viable. 
    

   NO DISTRIBUTIONS OR DIVIDENDS. The Company has not paid dividends on its
Common Stock and does not intend to do so in the foreseeable future. See
"Dividend Policy."

   
   MAINTENANCE  CRITERIA  FOR  NASDAQ  SECURITIES.  In order to  continue  to be
included in the Nasdaq National Market ("NNM"),  a company must maintain 200,000
publicly  held  shares,  a $1 million  market  value of its public  float and $1
million in net tangible assets (total assets,  excluding  goodwill,  minus total
liabilities).  In addition,  continued inclusion requires two market-makers,  at
least 300  holders of the Common  Stock and a minimum bid price of $1 per share;
provided, however, that if a company falls below such minimum bid price, it will
remain eligible for continued inclusion in NNM if the market value of the public
float is at least $3 million  and the  Company  has $4  million in net  tangible
assets.  The Company's failure to meet these maintenance  criteria in the future
may result in the discontinuance of the inclusion of its securities in NNM. As a
result,  an  investor  may find it more  difficult  to  dispose  of or to obtain
accurate quotations as to the market value of the securities.

                     LIMITED LIABILITY COMPANY DISTRIBUTIONS

   The Company's predecessor,  Houston, was an Arizona limited liability company
which was not  obligated to pay federal or state income  taxes.  The earnings of
Houston were treated, for federal and state income tax purposes,  as if they had
been earned directly by their respective members. For the fiscal years ended May
31, 1995 and 1996,  Houston made  distributions to its members totaling $692,817
and $1,300,000,  respectively, which amount was intended, in part, to offset the
members' tax liability. See "Certain Transactions."

                                 DIVIDEND POLICY

   The Company has never paid cash  dividends  on its Common  Stock and does not
anticipate  paying  such  dividends  for the  foreseeable  future.  The  Company
anticipates all earnings,  if any, will be retained for future investment in its
business.  Any  future  determination  to  pay  cash  dividends  will  be at the
discretion  of the Board of Directors  and will be dependent  upon the Company's
results of operations,  financial condition and other factors deemed relevant by
the Board of Directors.

                                 CAPITALIZATION

   
   The following table sets forth the capitalization of the Company as of August
31,  1996 on an actual  basis and as  adjusted  to  reflect  the  estimated  net
proceeds  from the sale of  1,300,000  shares of  Common  Stock  offered  by the
Company  hereby at an  assumed  offering  price of $7.00 per  share.  This table

   The selected financial data for each of the two years in the period ended May
31, 1996 are derived from financial  statements of the Company,  which have been
audited by Coopers & Lybrand  L.L.P.  The Company has never declared or paid any
cash dividends on shares of its capital stock.  The selected  financial data for
the three  months  ended  August 31,  1996 and 1995 are derived  from  unaudited
financial statements of the Company and include all adjustments, consisting only
of normal recurring adjustments, that the Company considers necessary for a fair
presentation  of the financial  position and the results of operations for these
periods. As with all quarterly results,  the Company's operating results for the
three months ended August 31, 1996 are not necessarily indicative of the results
that may be expected for the entire year. The selected  financial data should be
read in  conjunction  with  "Management's  Discussion  and Analysis of Financial
Condition and Results of Operations"  and the Company's  Consolidated  Financial
Statements and related Notes thereto and other financial  information  appearing

(1) For the two years ended May 31, 1996, Houston elected under Internal Revenue
    Code  Sub-Chapter  K to be  treated  as a  limited  liability  company,  and
    accordingly,  generally  was not subject to federal and state income  taxes.
    For income tax reporting  purposes for these years,  all profits and losses,
    and certain  other  items,  were  passed  through to the members of Houston.
    Since the income of the Company will be taxable  after May 31, 1996,  income
    tax expense for the years ended May 31, 1996 and 1995 has been  presented as
    if the  Company  was a C  corporation  during  those  years.  The income tax
    expense was calculated assuming an effective tax rate of 40%.

                                    DILUTION

   The net tangible book value of the Company at August 31, 1996 was $1,611,525,
or $0.54 per share. Without taking into account any changes in net tangible book
value  subsequent  to August 31, 1996,  other than to give effect to the sale of
1,300,000  shares of Common  Stock  offered by the Company  hereby at an assumed
initial  public  offering  price of $7.00 per share and after  deduction  of the
estimated  underwriting  discount and estimated Offering expenses payable by the
Company  estimated to be $690,000,  the pro forma net tangible book value of the
Company's Common Stock at August 31, 1996 would have been  $9,202,525,  or $2.14
per share.  This represents an immediate  increase in net tangible book value of
$1.60  per share to  existing  stockholders  and an  immediate  dilution  in net
tangible  book value of $4.86 per share to investors  purchasing  shares in this
Offering.  The following table  illustrates the per share dilution at August 31,
1996:

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

   The following  discussion is intended to provide an analysis of the Company's
financial  condition and results of operations and should be read in conjunction
with the  Company's  Consolidated  Financial  Statements  and the Notes  thereto
contained  elsewhere in this Prospectus.  The matters  discussed in this section
that  are  not   historical  or  current  facts  deal  with   potential   future
circumstances and developments.  Such forward- looking statements  include,  but
are not limited to, the  development  and market  acceptance  for new  products,
trends  in the  results  of the  Company's  operations  and the  mix of  product
revenues.  The Company's actual results could differ materially from the results
discussed  in the  forward-looking  statements.  Factors  that  could  cause  or
contribute to such  differences  include those  discussed below as well as those
discussed under the caption "Risk Factors" and elsewhere in this Prospectus.

OVERVIEW

   M.D. Labs, Inc.  (together with its  subsidiaries,  the "Company")  packages,
markets and distributes  natural dietary  supplements,  consisting  primarily of
herbal products and sports nutrition  products,  as well as a weight  management
chewing gum product. The Company has focused on new product innovation,  such as
its Daily Detox(R) teas targeted to the detoxification herbal tea market and its
Citrium(TM)  chewing  gum  targeted  to the  weight  loss  chewing  gum  market.
Currently,  the Company's products are segmented into three primary  categories:
(i) the all natural herbal tea and  supplements  line,  (ii) the weight loss and
other chewing gum lines, and (iii) the amino acid sports nutrition product line.

   For the fiscal year ended May 31, 1996, the Company's  sales were as follows:
72% from the herbal line;  25% from the chewing gum line; and 3% from the sports
nutrition  product line. The Company does not believe that such historical sales
are  representative  of future  sales  trends  due to high  initial  demand  for
Citrium(TM)  resulting  from  strong  introductory  advertising  and the initial
novelty of the product.  Further, the Company did not enter the sports nutrition
business until January 1996.

   Net sales have  increased to $5.2 million in fiscal 1996 from $4.2 million in
fiscal 1995.  The growth in sales  primarily is  attributable  to the successful
launch of the Citrium(TM)  and Women's  Nature(TM) -- Natural Balance herbal tea
in fiscal  1996,  as well as a  significant  increase  in  international  sales.
International  sales increased to approximately  17.4% of the Company's sales in
fiscal  1996,  as  compared  to  approximately  2.5% in  fiscal  1995.  However,
substantially all of the increase in international  sales was due to the sale of
Citrium(TM) to a large  distributor in Japan,  and there are no assurances  that
these sales will continue at this level in fiscal 1997.

   The  Company   distributes   its   products   through  its   in-house   sales
representatives,  who call on the approximately  8,000  independent  health food
store   operators,   and  through  several  large  domestic  and   international
distributors.  Recently,  the Company  has made  initial  sales to certain  mass
retailers, such as large regional and national retail food and drug stores.

   Generally,  the Company's sales are not seasonal, with the primary exceptions
being (i) an increase in sales at the  beginning of the calendar year related to
new year  fitness  resolutions  and (ii) a decrease in tea sales  during  summer
months.  Currently,  the Company has 26 full-time  employees,  though management
believes this number will increase based upon anticipated Company growth.

   The Company seeks to achieve revenue growth from three primary  sources,  (i)
growth of the Company's existing product lines, (ii) new product development and
(iii) product line and operating company acquisitions.  At the present time, the
Company does not have any understanding,  commitment or agreement  regarding any
acquisition.

   
   The Company  continues  to focus on new product  innovation.  The Company has
numerous  products in various  stages of research and  development  for possible
introduction in fiscal 1997 and  thereafter,  including a line of coffee chewing
gums,  a  Citrium(TM)  tea,  and new,  complementary  lines of sports  nutrition
supplements.  The Company  expects that a gum, an herbal tea and at least one of
the sports nutrition  products will be introduced in the third quarter of fiscal
1997. However,  there can be no assurance that any new product can be introduced
successfully or on a timely basis.
    
                                       20
<PAGE>
   The  market  for  the  Company's   products  is  characterized  by  extensive
competition,  frequent  new product  introductions,  short  product life cycles,
rapid product  declines,  eroding  profit  margins and changing  preferences  of
consumers. A decline in the demand for any of the Company's products, whether as
a result of competition,  changes in demographic trends or other factors,  could
have a material adverse effect on the Company's  business,  financial  condition
and results of operations.

   On May 31, 1996, the Company  exchanged  3,000,000 shares of its common stock
for all of the membership  interest in Houston  Enterprises,  L.L.C., an Arizona
limited liability company  ("Houston"),  and the financial statements at May 31,
1996  reflect  that  exchange.  For the years ended May 31,  1995 and 1996,  the
Company's  predecessor was taxed as a limited liability company.  For income tax
reporting  purposes,  all profits and losses for such years,  and certain  other
items, were passed through to the members of Houston.  Because the income of the
Company  will be  taxable  after May 31,  1996,  certain  temporary  differences
between  financial  and tax  reporting are reflected as an income tax benefit in
the statement of income for the years reported and as deferred tax assets in the
balance sheets for the years reported.

RESULTS OF OPERATIONS

   
   The  following  table sets forth the  consolidated  statements  of income and
percentages  of net  sales  represented  by the  individual  line  items for the
periods  presented.  These operating results and percentages are not necessarily
indicative of anticipated results for any future period.

   NET  SALES.  Net  sales for the  quarter  ended  August  31,  1996  increased
approximately  $81,000 or 8.3%, compared to the same quarter during fiscal 1996.
The increase in net sales is primarily  attributable  to increased  sales of the
Company sales of the PRO-LINE(R)  product line which was acquired by the Company
in January 1996. See "Risk Factors -- Uncertainty  Regarding Proprietary Rights"
and "Business -- Products;  Sports  Nutrition  Products." The Company's sales in
the first quarter of fiscal 1997 were lower than the sales in both the third and
fourth  quarters of fiscal 1996 due to decreases in sales of Citrium(TM)  gum in
Japan.  See "Business -- Litigation."  Based on the preceeding,  the Company may
not achieve  comparable  sales and net income in fiscal 1997 as it did in fiscal
1996.

   The Company  generally  sells products on net 30-day terms.  As of August 31,
1996 and May 31,  1996,  the  Company's  accounts  receivable  balances,  net of
allowances  for doubtful  accounts,  were  approximately  $521,000 and $620,000,
respectively.  Allowances  for  doubtful  accounts  were  $25,000  and  $27,876,
representing  4.6% and 4.3% of the  gross  accounts  receivable  balances  as of
August 31, 1996 and May 31, 1996, respectively. Included in these balances was a
receivable  from Revco Drug Stores  ("Revco")  for  approximately  $70,000.  The
Company shipped  approximately  $161,000 of its Citrium(TM) chewing gum to Revco
during  the  fiscal  year  ended May 31,  1996  pursuant  to a  guaranteed  sale
agreement  allowing Revco to return all Citrium(TM) not sold 120 days subsequent
to receipt.  The sales  agreement  required  that Revco pay for all sales as the
product was  actually  sold.  For  financial  reporting  purposes,  only the gum
actually  sold by Revco is recorded  as sales.  The  120-day  return  period has
lapsed, and Revco has elected to retain the unsold gum and remit payment for the
sold Citrium(TM). On October 16, 1996, the Company collected
    
                                       21
<PAGE>
   
$90,796 from Revco,  representing  payment in-full for their accounts receivable
balances as of May 31, 1996 and August 31, 1996.  It is generally  the Company's
policy to establish a reserve for  customer  accounts  receivables  greater than
approximately 90 days past due.

   COSTS OF GOODS SOLD.  Cost of goods sold for the first quarter in fiscal 1997
as compared to the first quarter in 1996 increased approximately $62,000, and as
a percentage  of net sales  increased  from 26.5% to 30.3% for the same periods.
This  increase  in cost of goods sold is due to a change in the mix of  products
sold during the quarter  ended August 31, 1996 with the addition of  PRO-LINE(R)
and other non-tea products which have lower gross margins.

   SELLING,  GENERAL & ADMINISTRATIVE EXPENSES. For the quarter ended August 31,
1996  selling,  general  and  administrative  expenses  increased  approximately
$101,000  or 21.7%,  as  compared to the quarter  ended  August 31,  1995.  This
increase  in  selling,   general  and   administrative   expenses  is  primarily
attributable to increases in three expense categories.  During the first quarter
ended  August 31,  1996  payroll and related  expenses  increased  approximately
$47,000 due to increased salaries  expenditures for certain officers, as well as
the addition of new employees and merit raises.  Secondly,  advertising  expense
increased  approximately  $24,000  during  the  quarter in  connection  with the
Company's expanded marketing plan in fiscal 1997. Lastly,  professional expenses
incurred  during the first  quarter of fiscal  1997  increased  $10,000,  due to
various  non-capitalizable  professional  fees  associated  with  the  Company's
growth.

   INTEREST  EXPENSE.  During the first  quarter  of fiscal  1997,  the  Company
incurred  approximately  $11,000 in interest expense  associated with the Belfer
Labs Note and the  Olympian  Global  Note,  both of which were  executed  by the
Company in the second half of fiscal 1996.

   NET SALES. Net sales for the year ended May were $5.2 million, an increase of
$997,000 or 24% compared to the same period  during  fiscal 1995.  The growth in
sales  primarily is  attributable  to the successful  launch of Citrium(TM)  and
Women's  Nature(TM) -- Natural  Balance  herbal tea in fiscal 1996, as well as a
significant  increase in international  sales.  International sales increased to
approximately  17.4% of the  Company's  net sales in fiscal  1996,  compared  to
approximately 2.5% in fiscal 1995. However, substantially all of the increase in
international sales was due to the sale of Citrium(TM) to a large distributor in
Japan,  and there are no assurances that these sales will continue at this level
in fiscal 1997. Sales of the Company's  Naturally Klean(R) and related products,
and Citrium(TM) products accounted for approximately 51% and 25%,  respectively,
of the Company's net sales for the fiscal year ended May 31, 1996.
    

   COST OF GOODS SOLD.  Cost of goods sold for fiscal 1996  decreased  from $1.6
million to $1.5 million, a decrease of $98,000 or approximately 6.1% from fiscal
1995. As a percentage of net sales,  costs of goods sold decreased from 38.4% to
29.1%  between  the  same  periods.   The  reduction   resulted  from  increased
efficiencies in purchasing herbs and other raw materials, as well as fiscal 1996
reductions in the volume of  discounted  sales and in the  distribution  of free
sample  products and  literature.  In  addition,  a  significant  portion of the
Company's cost of goods sold is composed of fixed costs,  which did not increase
in proportion to increased  fiscal 1996 sales.  The Company does not  anticipate
that this trend will continue in fiscal 1997, in part because raw material costs
are volatile and outside the  Company's  direct  control.  See "Risk  Factors --
Reliance on Outside Suppliers and Manufacturers."

   SELLING, GENERAL & ADMINISTRATIVE EXPENSES.  Fiscal 1996 selling, general
and administrative expenses increased $129,000 or 6.4% over fiscal 1995, yet
decreased as a percentage of net sales from 48.0%
                                       22
<PAGE>
to  41.3%  in  such  periods.  The  dollar  increase  in  selling,  general  and
administrative expenses is primarily attributable to the net effect of increases
in three expense categories, offset by a significant decrease in another expense
line item. In fiscal 1996,  professional fees increased $75,000 due to increased
accounting  and legal fees  associated  with the Company's  growth,  and payroll
increased  approximately  $88,000 due to merit pay increases and the addition of
new  personnel.   Additionally,   Company  advertising  increased  approximately
$179,000 due to the initial marketing campaigns required for several new product
launches in fiscal 1996, as well as a general increase in advertising for all of
the  Company's  other  products.  These  expense  increases  were  offset by the
termination on December 31, 1995 of the Company's consulting agreement with Pure
Source  International,  Ltd., an affiliated British Virgin Island company ("Pure
Source")   which  provided   marketing,   purchasing,   promotional   and  other
international  advertising  services  for  the  Company.  The  Company  incurred
$353,600 in expenses under the Pure Source  arrangement in fiscal 1995 and $0 in
fiscal 1996. See "Certain  Transactions."  The Company  anticipates  significant
increases in marketing  and  advertising  expenses in fiscal 1997 in  connection
with the  introduction  of new  products  and  increased  promotion  of existing
products.  Increased  sales resulting from such expenses may not be realized for
several quarters after such expenses are incurred, if at all.

   On May 31,  1996,  the members of Houston  completed a private  placement  of
portions of their Houston membership  interests,  selling approximately 16.6% of
their interests. The Company did not receive any proceeds from the sale. On that
same date, all members  converted  their  interests into shares of the Company's
Common Stock.  Private  placement  costs  associated  with the  transactions  of
approximately $70,000 were paid by the Company.

   
   INTEREST  EXPENSE.  The Company  incurred  approximately  $13,000 in interest
expense in the third and fourth  quarters  of fiscal  1996  associated  with the
Belfer Labs Note and the Olympian  Global Note,  both of which were  executed in
fiscal 1996.

   INCOME TAX BENEFIT.  The Company  recognized an $86,000 income tax benefit in
fiscal year 1996 due to the income tax effect of temporary  differences  between
financial  and income tax  reporting  purposes.  For the two years ended May 31,
1996,  Houston  elected  to be  treated  as a  limited  liability  company,  and
generally  was not  subject to federal and state  income  taxes.  The  Company's
income  is  taxable  commencing  June 1,  1996,  and the  Company  estimates  an
effective tax rate for fiscal 1997 of 40%.
    

INFLATION

   Management  does not believe that inflation has had a material  effect on the
Company's sales or results of operations during the past two fiscal years.

LIQUIDITY AND CAPITAL RESOURCES

   
   The Company  traditionally has financed its capital needs from net cash flows
from  operations.  In fiscal 1996,  the Company  generated  $1.1 million in cash
flows from operating activities, as compared to $475,000 in fiscal 1995. For the
quarter ended August 31, 1996, the Company generated  approximately  $193,000 in
cash flows from operating activities,  as compared to approximately $290,000 for
the same  quarter in fiscal 1995.  As of August 31, 1996 and May 31,  1996,  the
Company had working capital of approximately $1.3 million and $1.2 million, with
current ratios of 3.18 and 2.77,  respectively.  Management believes the Company
will  continue  to generate  cash flows from  operating  activities  in the near
future.  The Company  anticipates  utilizing  the proceeds from this Offering to
finance new product  research  and  development  and  product  introduction  and
expanded general advertising campaigns,  manufacturing and warehouse automation,
computer system upgrades, and for possible product line and/or operating company
acquisitions,  as well as repayment of indebtedness discussed below. The Company
anticipates  spending  approximately  $500,000 of the Offering  proceeds for the
development of an in-house  manufacturing  facility for certain of its products.
The Company  expects  that such  manufacturing  facilities  will be  sufficient,
together with the Company's  existing supply  arrangements to meet the Company's
current  needs and does not have any  immediate  plans to  construct  additional
manufacturing facilities.

   As of August  31,  1996,  the  Company  had  approximately  $1.1  million  in
inventory.  Such inventory  balances are greater than desired primarily due to a
build up in chewing gum inventories and raw
                                       23
    
<PAGE>
   
materials  required for the Company's recently launched products and products in
development.  Management  intends to reduce these inventory balances through the
routine sale of its products prior to the end of fiscal 1997.
    

   On March 6, 1996,  the  Company  borrowed  $300,000  from Belfer Labs LLC, an
affiliated company formed by Todd Belfer, president and director of the Company,
and Harvey  Belfer,  father of Todd Belfer and  consultant  and  director of the
Company.  The Belfer Labs Note accrues interest at the rate of 12% per annum and
is payable March 6, 1997. The proceeds of the Belfer Labs Note were  distributed
to the members of Houston for,  among other  things,  the member's tax liability
which  resulted  from the  profitable  operations  of the  Company  prior to the
Company's  conversion  to a  corporation.  On July 23,  1996,  the Company  paid
$100,000 in principal on the note plus accrued  interest of $14,100.  Management
anticipates repaying the remaining balance payable on the note with the proceeds
from this Offering. See "Use of Proceeds" and "Certain Transactions."

   
   At the present time the Company believes that it is in substantial compliance
with all  regulatory  and  enforcement  requirements.  Due to the  uncertain and
evolving nature of the regulatory  environment in which the Company operates, it
is possible  that the Company is unaware of  non-compliance  which could subject
the Company to remedial costs having a material  adverse effect on the Company's
operating  results and  liquidity.  See  "Business  --  Government  Regulation."
Because such costs, if any, are  unpredictable,  the Company has not accrued any
contingent liabilities.
    

   The Company does not currently have a working capital line of credit or other
term financing from a financial  institution,  nor has any financial institution
committed to provide any such financing to the Company.

   The Company  believes the net proceeds from this Offering and cash  generated
from operations  will be sufficient to fund its operations  through fiscal 1997.
There can be no assurance, however, that the Company will not require additional
capital in the future,  particularly for acquisitions of products or businesses.
If the Company were required to obtain additional financing in the future, there
can be no  assurance  that such  sources of capital  will be  available on terms
favorable to the Company, if at all.

                                    BUSINESS

GENERAL

   M.D. Labs, Inc., a Delaware corporation (together with its subsidiaries,  the
"Company")   packages,   markets  and  distributes   natural  food  and  dietary
supplements,  consisting  primarily  of herbal  products  and  sports  nutrition
products,  as well as a weight management  chewing gum product.  The Company has
focused on new product  innovation,  such as its Daily Detox(R) teas targeted to
the detoxification herbal tea market and its Citrium(TM) chewing gum targeted to
the weight loss chewing gum market. The Company's products are sold generally to
distributors and to health food, drug and other retail stores.

   
   The  Company  was  incorporated  in  Delaware  on  February 7, 1996 to be the
successor  to  Houston  Enterprises,  L.L.C.  ("Houston"),  an  Arizona  limited
liability  corporation.  On  May  31,  1996,  the  Company  acquired  all of the
membership  interests in Houston and thereupon  succeeded to Houston's business.
Houston acquired its original line of products from Houston  Enterprises,  Inc.,
an Arizona  corporation,  through an asset purchase  completed in February 1994.
The  acquisition  cost to Houston was  determined  by  negotiations  between the
owners of Houston and the unrelated owners of Houston Enterprises, Inc. based on
their evaluation of the value of the assets involved. Houston Enterprises,  Inc.
introduced its first product line in 1987.

   In February  1996,  the Company  purchased  all of the  outstanding  stock of
Belnik Investment Group, Inc., an Arizona  corporation doing business as Freedom
Wholesalers,  Inc. ("Freedom"),  from Messrs. Hooman Nikzad and Todd Belfer. The
purchase  price  consisted of $1,000 plus warrants to purchase  21,000 shares of
the Company's  Common Stock  exercisable at $1.00 per share and vesting in three
equal annual installments  commencing December 31, 1996. This purchase price was
determined by a subjective  evaluation by the Company's management of the assets
and cash flows to be acquired offset by the liabilities  assumed inherent in the
types of  products  sold by  Freedom.  See  "Business  --  Products  --  Freedom
Products" and "Certain Transactions."

   In January  1996,  the Company  acquired  certain  assets of Olympian  Global
L.L.C., an Arizona limited liability company ("Olympian Global") for $50,000 and
a $210,000  note.  The assets  included the  "PRO-LINE(R)"  trademark,  Olympian
Global's  available  inventory of PRO-LINE(R)  products,  and a list of Olympian
Global's  PRO-LINE(R)  customers and sales  reports.  The Company  agreed not to
market for 36 months under the acquired  trademark any new products that compete
with products sold by Olympian  Global under the "Olympian Labs" trade name. The
Company  also is obligated  to pay royalty of 3% of the gross  selling  price of
each PRO-LINE(R)  product sold during the 30-month period commencing February 1,
1996 to Lance Dreher,  a former owner of assets  purchased from Olympian Global.
See "Business -- Product Royalties."
    

INDUSTRY BACKGROUND

   According to industry  sources,  the natural and organic  products  industry,
which includes vitamins,  supplements,  herbs,  personal care, natural medicines
and groceries,  and organic  clothing and household  cleaners,  grew over 20% in
1995 to approximately $9 billion in retail sales.  Herbs have been a significant
category in this industry in recent years.  The herb  category,  which  includes
dietary supplement formulas,  capsules,  extracts and teas such as those sold by
the Company,  as well as bulk and medicinal  herb sales,  has been  estimated to
exceed $1 billion in the United  States.  Industry  sources also  indicate  that
sales of sports nutrition products,  excluding  beverages,  were $675 million in
1995. See "Risk Factors -- No Independent Market Studies."

   The  Company  believes  that the growth in its  industry is  attributable  to
several  factors,  including  (i) expansion of natural  product  sales  channels
through natural foods supermarkets, health food stores, mainstream supermarkets,
drug  stores and mail order  catalogs,  (ii) the aging  population  focusing  on
alleviating  the  effects  of  age,  (iii)  increased   consumer  awareness  and
dissemination of academic  studies of the connection  between health and fitness
and nutrition,  and the hazards of chemical agriculture,  and (iv) the perceived
improvements in the regulatory  environment  resulting from the DSHEA. See "Risk
Factors -- Uncertainty and Potential Negative Effects of Government Regulations;
Non-Compliance   with  Government   Regulations"  and  "Business  --  Government
Regulation."
                                       25
<PAGE>
   Industry  data  indicates  that the primary  consumers of natural and organic
products are female, with at least some college education and a median household
income  of  approximately  $30,000.  Consumers  of  sports  nutrition  products,
however,  are  primarily  men aged 24 to 35, with that age group  shrinking  and
consumption by women over 35 increasing.  Such  consumers are  characterized  as
early to adopt new products and susceptible to change product  preferences.  See
"Risk Factors -- Short Product Life Cycles; Dependence on New Products."

   
   The Company estimates that the market for the Company's products now includes
not only the approximately 8,000 independent and chain health food stores in the
U.S.,  but also the several  hundred  thousand  drug stores,  supermarkets,  and
convenience  stores  across  the  country  and,  on  a  direct  response  basis,
individual  consumers.  Management  also believes the market for natural  health
food supplements outside of the United States has become a promising environment
for the Company's products.
    

STRATEGY

   The  Company is  pursuing a  three-pronged  growth  strategy  focusing on (i)
expansion  of sales of  existing  products  to  current  and new  customers  via
increased  advertising and marketing and  development of additional  channels of
distribution;  (ii)  development of new products which  complement the Company's
existing product lines or address new markets with significant growth potential;
and (iii) acquisition of other companies, products or product lines which, as in
the case of new products  under internal  development,  complement the Company's
existing product lines or address new markets with significant growth potential.
See "Risk Factors -- Limited Industry Experience;  Recent Business Venture," "--
Limited  Capitalization,"  and  "-Management  of  Growth."  Key  elements of the
strategy are as follows:

   Build  Brand  Name   Recognition.   The  Company  believes  that  brand  name
recognition  is an  increasingly  important  competitive  factor  in its  target
markets as key customers  tend to align  themselves  with fewer vendors of brand
name products.  The Company believes that it has established  significant  brand
name recognition in detoxification  markets. The Company intends to increase its
marketing and advertising  programs after  completion of the Offering to enhance
brand name  recognition of current  products and facilitate  introduction of new
product  offerings.  Because a  reputation  for quality  products is critical to
establishing  a successful  brand name,  the Company will also focus  efforts on
quality control. See "Risk Factors -- Competition and Low Barriers to Entry."

   Increase  Penetration in Domestic  Health Food Market.  The Company  believes
that the  expansion  of  retail  distribution  channels  and the  strong  growth
characteristics of the nutritional  supplement industry provide the Company with
significant  opportunities  to increase sales. The Company further believes that
increased  brand name  recognition  of the Company's  products will enable it to
increase its  penetration  of shelf space as health food retailers seek to align
themselves with companies  which possess strong brand names,  offer a wide range
of products, demonstrate continued marketing and advertising support and provide
high levels of customer service.

   Build Upon  Established  Customer  Relationships.  The Company's  established
relationships  with  distributors and health food store retailers are based upon
the  Company's  commitment  to a high level of customer  service.  The Company's
direct sales force and management work with direct  accounts,  distributors  and
individual retailers to build knowledge of the Company and its products, in turn
achieving increased exposure for these products.

   Continue to Introduce New Products and Product  Innovations.  The Company has
introduced  a number  of  innovative  new  products,  including  the  successful
introductions in fiscal 1996 of Citrium(TM)  weight  management  chewing gum and
Women's  Nature(TM)  -- Natural  Balance  herbal tea.  The  Company  obtains new
product concepts through independent  consultants,  naturopathic doctors, market
feed back  gained  from its  distributors  and  direct  sales  force,  and other
sources.  The Company  intends to continue to emphasize the  introduction of new
and  innovative  products not  previously  available in health food stores.  See
"Risk Factors -- Short Product Life Cycle;  Dependence on New Products," and "--
Competition and Low Barriers to Entry."

   
   Increase  Penetration of  International  Markets.  The Company  believes that
there are substantial  opportunities for growth in foreign markets. For example,
over $750,000 in sales of Citrium weight
    
                                       26
<PAGE>
   
management  chewing gum were achieved through  distributors  selling in Japan in
fiscal  1996,  and  marketing  relationships  have been  initiated  in  numerous
additional countries.  The Company intends to build upon existing  relationships
with  distributors  serving  primarily Japan,  Taiwan,  Canada and Korea, and to
establish  relationships in additional  countries to pursue growth opportunities
in foreign  markets.  During fiscal 1996,  the Company's  revenues from sales to
these   countries  were   approximately   $750,000  for  Japan  (from  sales  of
Citrium(TM)),  $78,000 for Taiwan (from sales of  Citrium(TM),  PRO-LINE(R)  and
Women's  Nature(TM)  products),  $55,000 for Canada (from sales of  Citrium(TM),
Daily Detox(R),  Daily Herbal(TM),  Naturally  Klean(R),  Women's Nature(TM) and
HerbalPathic(TM)  products)  and $10,000  for Korea (from sales of  Citrium(TM),
Daily Detox(R),  Womens  Nature(Tm) and  HerbalPathic(TM)  products).  See "Risk
Factors -- Product  Concentration"  and "-- Risks Associated with  International
Sales."

   Supplement  Internal Growth Through Strategic  Acquisitions.  The nutritional
supplement  industry is highly  fragmented with many companies  producing only a
single  product  line  or  single  product.  The  Company  believes  that  it is
positioned strategically to participate in the consolidation of the industry due
to the Company's  increasing  brand name  recognition and access to distribution
channels,  its  ability  to launch new  products,  and the  financial  resources
available upon  completion of this Offering.  The Company has added  significant
products in fiscal 1996 via the  acquisition  of Freedom (The  Stuff(TM) and the
discontinued  Naturally  High(TM)  product) and Olympian Global (the PRO-LINE(R)
products)  and  intends  to pursue  strategic  acquisition  opportunities  where
appropriate.  See "Risk Factors -- Selection and  Integration of  Acquisitions,"
"Business -- General" and "-- Products."

   Certain of the Company's  product  formulations  are marketed under different
packaging and labelling.  The Company currently markets the Naturally  Klean(R),

Sports Nutrition Products

   
   Super   ProLean(TM)  Fat  Burners,   DHEA,   Amino  Formula   "1240"(TM)  and
Chromoplex(TM).  The  PRO-LINE(R)  products  consist of a variety of nutritional

aid athletes in muscular recovery,  and  Chromoplex(TM),  a chromium  supplement
which  combines two forms of chromium to stabilize  insulin  levels and act as a
weight management supplement.  The Company entered the sports nutrition business
upon acquiring  certain assets from Olympian Global in January 1996. The Company
believes  that  Olympian  Global  may  have  breached  certain  aspects  of  the
acquisition   agreement   relating  to  the  trademark  and  trade  name  rights
transferred  thereunder by, among other things,  failing to transfer clean title
properly and failing to disclose a third-party's use of a similar mark which may
infringe on the  PRO-LINE(R)  mark.  The Company is unable to predict the extent
(if any) to which its rights to the acquired  trademarks  and trade names may be
affected  by this  matter.  However,  the Company  believes  that its efforts to
expand its lines of sports nutrition offerings will not be materially  adversely
affected  should  restrictions  exist  with  respect  to its  rights  to use the
acquired trademarks and trade names.
    

   The Company is in the process of  implementing  two extensions of its current
line of sports  nutrition  offerings.  The Company is  developing  a new line of
premium sports nutrition products to be marketed to health food stores and gyms.
The Company also is developing a separate line of sports  nutrition  products to
be marketed exclusively through professional  trainers.  The Company anticipates
that the new product lines will include weight management products.  The Company
intends to use a portion  of the  proceeds  from the sale of the Shares  offered
hereby in connection  with the  development  and  introduction  of these product
lines. See "Use of Proceeds." There can be no assurance that either product line
can be introduced successfully.  See "Risk Factors -- Short Product Life Cycles;
Dependence on New Products" and "--  Substantial  Portion of Proceeds to be Used
for New Product Introduction."

   Although  the above  products are listed with  indications  for use for which
they  have  been  designed,  the  Company  does not  necessarily  have  complete
scientific  substantiation  for  such  uses and the  Company  may not be able to
specifically  label and promote the products  for the  indicated  purposes.  The
purposes stated above are based on alternative  health  concepts,  which are not
necessarily  recognized by the conventional  medical  establishment,  or by such
regulatory  authorities  as the FDA and the FTC.  As  discussed  in the  section
"Business  --  Government  Regulation"  the Company may be required to limit the
promotional  and marketing  claims which it may make as  regulatory  enforcement
practices are clarified
                                       28
<PAGE>
and as  the  Company  moves  to  bring  itself  into  material  compliance  with
regulatory requirements.  There is no assurance that the Company will be able to
effectively market its products absent the ability to promote them for the above
purposes.  See "Risk Factors -- Uncertainty  and Potential  Negative  Effects of
Government Regulations" and "-- Non-Compliance with Government Regulations."

PRODUCT PLANNING, DEVELOPMENT AND ACQUISITION

   The Company  engages in the planning,  development  and  distribution of new,
specialty dietary supplements,  weight management and sports nutrition products.
See "Risk Factors -- Short Product Life Cycles;  Dependence on New Products" and
"--  Reliance  on Others to Develop  Products."  Although  it does not  maintain
in-house  research and formulation  expertise,  the Company engages  independent
consultants,  naturopathic  doctors,  and  other  experts  to  assist  it in the
development  of new  products.  Ideas for new products  come from many  sources,
including  the  Company's  management  and  consultants,   market  feedback  and
demographic  trend  analysis.  In addition,  some  products are presented to the
Company for acquisition.

   
   The Company  works to develop  innovative,  cost  effective new products from
conception  to full  production  including  the creation of product  samples and
packaging mock-ups. Each product is intended to achieve a high level of customer
satisfaction.  The Company estimates that research and development  expenditures
during fiscal 1995 and 1996 were approximately $1,424 and $781, respectively. In
addition, a substantial portion of the Company's product development  activities
are conducted in conjunction with third-party suppliers and manufacturers, which
generally invoice the Company for product ordered while not invoicing separately
for  development  costs  associated  with such  products.  In October 1996,  the
Company engaged a consultant to assist the Company with research and development
activities, including new product development. 
    

PRODUCTION

   
   The Company orders the raw materials used in its products primarily from U.S.
distributors,  most of which obtain the raw materials from Italy,  China, Egypt,
India and the United States. The Company's  principal raw material suppliers are
Marcor Development, Stryka Botanics, Interhealth, San Francisco Herb Company and
Stauber  Performance,  Ltd. The Company receives directly and inspects a portion
of such  materials  prior  to  trans-shipment  to its  manufacturers.  Most  raw
materials are shipped directly to the manufacturers  for inspection,  fumigation
and quarantine, if necessary, and processing.
    

   The Company's  products are obtained through oral agreements with independent
third-party manufacturers and manufacturers' representatives, primarily Business
Development  Labs,  Inc.  and  Willow   International   Marketing,   Inc.  These
manufacturers  agree to  produce  products  in  accordance  with  the  Company's
specifications.  All  finished  products  are shipped to the Company in bulk for
packaging,  labelling,  and in-house  order  fulfillment.  See "Risk  Factors --
Absence of Clinical Studies,  Scientific Review and Testing." The Company has no
written  agreements  with its third-party  manufacturers  governing the services
they  provide.   See  "Risk  Factors  --  Reliance  on  Outside   Suppliers  and
Manufacturers."

   The Company  anticipates  that it will  develop the  capability  to perform a
significant portion of its production  capability internally over the next year,
but there can be no assurance that such  capability will be developed or that it
will provide significant cost savings if developed.

   
   The Company is  contemplating  the  development of an in-house  manufacturing
facility for certain of its products.  The manufacture of dietary supplements is
subject to a requirement for conformance to Good  Manufacturing  Practices.  See
"Business -- Government  Regulation." The Company  therefore will be required to
establish  facilities  for the  laboratory  testing of incoming  raw  materials;
control of raw materials;  storage and handling;  documentation of manufacturing
procedures; and final product quality assurance testing. These requirements also
apply to the Company's existing repackaging  procedures.  The full extent of the
Good Manufacturing  Practices  requirements is not yet known, but it is expected
that this  will  require  the  Company  to hire  additional  skilled  personnel,
purchase specialized technical equipment, and set aside portions of its facility
for  the  support  and  maintenance  of  proper  good   manufacturing   practice
procedures. 
    
                                       29

MARKETING

   The Company's  marketing  strategy is to offer  quality,  unique  products in
niche markets with distinguishable  characteristics,  such as detoxifying herbal
teas, herbs designed to aid digestion and herbal tea for PMS, weight  management
chewing gum and the like. The Company's  strategy also includes  positioning its
products as innovative, competitively priced and effective.

   
   The Company  presently sells its products  through  distributors and brokers,
combined with an in- house direct sales force,  into drug stores,  supermarkets,
sporting  goods  stores,  and other  high  volume  retailers,  and to  consumers
directly.  The Company's three largest customers (Naoki  Corporation,  RegaLabs,
Inc. and Forcite  Distributors)  accounted  for  approximately  $1.25 million in
sales, or approximately 24.0% of fiscal 1996 net sales. The Company supports its
marketing  strategy  with a national  advertising  campaign in the print  media,
mainstream sports and fashion magazines and television advertising, all prepared
and placed using the Company's public relations and advertising departments. The
Company  advertises in publications such as Time,  Vegetarian Times,  Let's Live
and Natural Health. The Company intends to continue to use full-color brochures,
flyers, floor and counter displays, packaging and labels created by its in-house
advertising  and marketing  department  for each  product.  See "Risk Factors --
Accounts  Receivable" and "-- No Independent  Market  Studies." The Company also
plans to increase its share of the herbal  detoxification  market  through trade
shows,   advertising,   public  relations,   corporate  communications  and  the
aggressive marketing of its natural products, including direct response and mail
order marketing.
    

   The Company also  publishes a periodic  multiple page  newsletter  called the
Health  Advocate  which  contains  articles  related  to  the  natural  products
industry,  general  health,  the  environment  and recent events at the Company.
Distribution generally includes health food retailers and wholesalers, trade and
non-profit organizations,  health professionals, and the media. The Company also
operates a "Press Alert" marketing program through which it informs the media of
newsworthy  events  and  information  related to health,  the  environment,  the
natural products  industry,  and recent Company events. As a policy, the Company
makes decisions with consideration to their environmental impact,  including the
production of packaging, stationary, labels, and the like.

   To capitalize on the increasing  international  demand for alternative health
care products,  the Company's  strategy also includes  increasing  product sales
through marketing abroad using foreign  distributors and brokers,  export guides
and trade shows. The Company has initiated  distribution in Canada,  Mexico, the
United Kingdom,  Japan,  Thailand,  Korea, Taiwan,  Australia,  Greece and other
countries,  and intends to establish  distribution in additional  countries.  To
date, the majority of international sales have been effected in Japan. See "Risk
Factors -- Customer  Concentration"  and "-- Risks Associated With International
Sales."

COMPETITION

   
   Although the Company  believes that its herbal  detoxification  products were
among the first of such products marketed  nationwide,  competing  products have
been introduced into the market. Similarly,  while the Company's Citrium(TM) has
gained rapid  acceptance in the market,  the Company has  experienced  increased
competition  for  market  share.  The  market  for  the  Company's  products  is
characterized  by  competitive  factors  such  as  product   innovation,   brand
recognition and effective  marketing and distribution.  The Company's  principal
competitive  advantage in the marketplace  has been the specialty  nature of its
products  and the  market  niches  they  occupy.  By  focusing  on  high-margin,
specialty products with innovative  formulations and packaging,  the Company has
enhanced its competitive position.  Nevertheless, the market for natural dietary
supplements, weight management and sports nutrition products is characterized by
extensive competition,  frequent new product  introductions,  short product life
cycles, rapid price declines and eroding profit margins,  together with changing
customer  preferences and demographics.  The Company expects to face substantial
competition  in its efforts to capture and maintain a market share in its target
markets.  Numerous small,  private companies as well as larger companies such as
Twinlab Corporation,  Gumtech International,  Inc., BNG Enterprises, Inc. (which
does business as Herbal Klean),  Weider Nutrition,  Inc., Nature's Secret, Inc.,
Nature's Way, Inc. and Celestial  Seasonings,  Inc.,  currently  offer competing
products, and additional competition can be expected. In addition, there 
    
                                       30
<PAGE>
are a variety of channels of  distribution  for dietary  supplements and for the
Company's other products  including  direct  response  marketing and multi-level
distribution,  although the latter is not  utilized by the Company.  Many of the
Company's existing competitors have greater financial,  marketing,  distribution
and research  capabilities than the Company. The performance of the Company will
depend on its ability to develop and market new products  that can gain customer
acceptance and loyalty, as well as the Company's ability to adapt to its product
offerings to meet changing  market  conditions,  including  price  pressures and
other factors. See "Risk Factors -- Competition and Low Barriers to Entry."

PROPRIETARY RIGHTS: TRADE NAMES, TRADEMARKS AND COPYRIGHTS

   
   The Company owns registrations issued by the U.S. Pat. Off. for the following
trademarks:  Naturally  Klean(R),  Daily Detox(R),  and Daily Klean. The Company
entered  into  an  agreement  with  Olympian  Global  in  January  1996  for the
acquisition of rights to the federally  registered  trademark,  PRO-LINE(R),  as
well as certain related names and marks.  The Company  believes  Olympian Global
may have breached certain aspects of the acquisition  agreement  relating to the
trademark and trade name rights transferred thereunder. The Company is unable to
predict the extent (if any) to which its rights to the  assigned  trademark  and
trade name may be affected by this matter.  See  "Business -- Products -- Sports
Nutrition  Products." The U.S. Pat. Off. has issued Notices of Allowance for the
following  trademarks:  Women's Nature(TM),  Daily Herbal(TM),  and Citrium(TM).
Thereafter,  the  Company  filed  Statements  of Use  providing  evidence of the
Company's  use of  each  of  these  marks.  If  the  evidence  of use is  deemed
satisfactory by the U.S. Pat. Off.,  federal  registrations  should issue within
six months.  Applications for federal registration have been filed with the U.S.
Pat. Off. for the following trademark and servicemark:  "M.D. Labs." The Company
has filed  applications  for Citrium(TM) in the European  Community (CTM) and in
South Korea. For all products in development, name searches and applications for
registration  are  submitted  regularly.  See "Risk  Factors --  Uncertainty  of
Proprietary Rights."

   The Houston International tradename has not been registered and an associated
logo has not been registered as a trademark, though the Company claims rights to
use the Houston  International  trade name and the associated  logo under common
law. The Company has recorded a fictitious name  certificate in Maricopa County,
Arizona, for the Houston International name.
    

PRODUCT ROYALTIES

   The Company has entered into a royalty agreement regarding Women's Nature(TM)
PMS herbal tea with a  consultant  (the "WN  Consultant"),  which  calls for the
payment of a royalty of nine cents ($0.09) for each unit of the product sold for
18 months from March 15, 1995,  the date the first unit was sold,  and a royalty
of five cents ($0.05) thereafter (the "Women's  Nature(TM)  Royalty  Contract").
The Women's  Nature(TM)  Royalty Contract calls for the WN Consultant to aid the
Company in developing Women's  Nature(TM) PMS herbal tea through  consultations,
research,  formulation  experiments and other procedures necessary to design the
product. The WN Consultant reserved the right to examine and approve all product
labeling, press releases, brochures and other material used to promote or market
the product prior to distribution.  The original  three-year term of the Women's
Nature(TM)  Contract  expires on March 14, 1998,  three years from its effective
date,  and is  automatically  renewed for an additional  three-year  term unless
either party provides advance written notice of intent not to renew prior to the
end of any such term.  On such  notice,  the  Company is entitled to continue to
sell Women's  Nature(TM) PMS herbal tea and use the WN  Consultant's  name until
all  inventory in stock and/or on order is  exhausted.  Thereafter,  the Company
forfeits the right to use any reference to the WN Consultant in association with
Women's  Nature(TM)  PMS herbal tea and the WN Consultant  forfeits the right to
any royalty  payments for any sales occurring after the end of the last term and
the exhaustion of all inventory in stock and/or on order. The Women's Nature(TM)
Royalty Contract also contains non-disclosure and non-competition provisions.

   The Company has entered into an additional  agreement  with the WN Consultant
dated February 21, 1996,  governing Women's Nature(TM) -- Natural Balance herbal
tea and calling for the same terms, including royalties and automatic renewal of
its  three-year  term, as apply under the Women's  Nature(TM)  Royalty  Contract
discussed above.
                                       31
<PAGE>
   
   The Company's obligation to pay a royalty to a consultant with respect to the
sales of Citrium(TM) has been terminated by mutual  agreement in September 1996.
The  Company  also  agreed to pay a former  owner of the assets  purchased  from
Olympian  Global a  royalty  of 3% of the  gross  selling  price of each unit of
PRO-LINE(R)  product sold during a 30-month period commencing  February 1, 1996.
Olympian Global guaranteed that gross monthly sales of the PRO-LINE(R)  products
would average $40,000 per month during the six-month period  following  closing,
and agreed that if the total gross sales for such products  during the six-month
period were less than  $240,000,  the principal  balance due under the Company's
note ($160,000 as of August 31, 1996) would be reduced by the same amount, up to
a $160,000  reduction.  Through  July 31, 1996,  the Company sold  approximately
$224,000 of PRO-LINE(R)  products;  however,  a formal reduction in the note has
not yet been  prepared.  The note also provides that if certain sales levels are
reached prior to January 13, 1997,  the Company must pay an additional  $40,000.
The note is  collateralized  by the rights to the PRO-LINE(R) name and mark. The
Olympian  Global note is payable in full at the  earlier of February  1997 or 30
days after  completion of the Company's  initial  public  offering.  The Company
believes  that  Olympian  Global  may  have  breached  certain  aspects  of  the
acquisition   agreement   relating  to  the  trademark  and  trade  name  rights
transferred thereunder.  The Company is unable to predict the extent (if any) to
which its  rights to the  acquired  trademarks  and trade  names or the  payment
obligations under the note may be affected by this matter.
    

PRODUCT LIABILITY

   
   The natural dietary  supplement,  weight loss management and sports nutrition
markets  are  subject  to  product  liability  claims.  Many  of  the  Company's
competitors  have been sued for injuries  alleged to have occured as a result of
using their products.  Recently,  several  companies have been sued for injuries
and wrongful  death  arising out of the use of products  containing  ma huang or
ephedrine.  The Company  marketed a product  containing  ma huang under the name
Naturally  High(TM).  The State of New York banned the sale and  distribution of
Naturally High(TM) and 19 competitors'  products due to reports linking products
containing ma huang or its active  ingredient,  ephedrine,  to adverse reactions
such as heart problems,  stroke and at least 15 deaths  nationwide.  The Company
has  discontinued  all  sales of  Naturally  High(TM)and  has not  received  any
indications  or notice of any claim  against it arising  out of its sale of that
product.

   The  Company  has never been  served  with a lawsuit  based upon any  product
liability claim to date.  Because of the inherently  differing  sensitivities of
various  individuals  to certain  chemicals and chemical  combinations  found in
dietary supplements,  some risk of product liability is unavoidable. The Company
has purchased  product and general  liability  insurance with general  aggregate
limits of $2 million and a $3 million excess  liability  umbrella  policy.  Such
policies provide coverage of up to $1 million for each occurrence.  The policies
are subject to annual renewal.  There can be no assurance that liability  claims
will not exceed the  coverage  limit or be excluded by coverage  limitations  or
that such  insurance  will continue to be available on  commercially  reasonable
terms or at all.  Consequently,  product  liability claims could have a material
adverse effect on the business, financial condition and results of operations of
the Company.  The Company has not  experienced any product  liability  claims to
date. See "Risk Factors -Effect of Discontinued Product" and "-- Risk of Product
Liability Claims." 
    

GOVERNMENT REGULATION

   The formulation,  processing, packaging, labeling, product claims advertising
and marketing, including direct marketing, of the Company's products are subject
to  regulation  in the U.S. by one or more federal  agencies,  including but not
limited  to the FDA,  the FTC,  the CPSC,  the USDA,  the United  States  Postal
Service, and the EPA. These activities are also regulated by various agencies of
the states and localities in which the Company's products are sold. In addition,
the Company is also subject to regulation by the Occupational  Safety and Health
Administration.

   The most extensive regulations applicable to the Company's operations is that
of the FDA enforcement under the FDCA. This statute, with which the Company must
comply,  establishes a comprehensive  regulatory  scheme  enforceable by various
civil and criminal actions.  The Company's  facilities are subject to inspection
and review by federal and state authorities.
                                       32
<PAGE>
   The Company's  business is in the industry commonly known as the "health food
industry"  which has been the subject of many years of  vigorous  administrative
and judicial  enforcement  by the FDA. The FDA has taken the position  that many
businesses  which  conduct  operations  similar to those of the  Company  are to
varying  extents in violation of the law. These efforts by the FDA have resulted
in a series of judicial decisions and legislative  enactments which have defined
the future course of this  industry.  On October 23, 1994, the DSHEA was enacted
and amended the FDCA,  particularly with regard to dietary  supplements.  In the
judgment  of the  Company,  this  new  law has  been  favorable  to the  dietary
supplement  industry but,  inasmuch as many aspects of the law have not yet been
fully interpreted or judicially applied, there is no assurance that this will in
fact continue to be the case.

   First and foremost,  the DSHEA  legislation  creates a new statutory class of
"dietary supplements." This new class includes vitamins,  minerals, herbs, amino
acids and other dietary  substances  for human use to supplement  the diet.  The
statute  establishes a new safety standard which dietary  supplements  must meet
and, in certain cases, authorizes the FDA to order dangerous dietary supplements
off the market. The statute  potentially  authorizes dietary supplements to make
so-called  structure  and function  claims  without  advance FDA  approval,  but
requires companies to give the FDA special notice when such claims are made, and
also to provide special labeling for products which make such claims.

   However,  procedures  previously  established  by the  FDA  for  approval  of
so-called  "health  claim"  messages  remain  in  full  force  and  effect.  The
regulations  prohibit the use of any claim for a dietary supplement,  unless the
health  claim  is  supported  by   significant   scientific   agreement  and  is
pre-approved  by the FDA.  To date,  the FDA has been  very  restrictive  in its
approach  to  "health  claims"  and has  approved  the use of health  claims for
dietary supplements only in connection with calcium and osteoporosis,  and folic
acid and neural tube defects.

   
   The  Company's  business  is in large  part  dependent  on the  making of the
so-called  structure  and  function  claims,  which do not  require  advance FDA
approval.  This type of claim is one where a product is  represented or intended
for use in  affecting  some  "structure  or  function"  of the human  body.  The
Company's  products (e.g.,  those relating to weight loss) are generally labeled
with this type of claim.  However,  the dividing  line between  "health  claims"
which do require advance approval,  and "structure and function claims" which do
not, has not been definitively determined.  There is no assurance that claims of
the type which the Company is  currently  making  will not become  subject to an
advance approval requirement.
    

   Under DSHEA, a dietary  supplement  which contains a new dietary  ingredient,
one not on the market as of October 15, 1994, will require evidence of a history
of use or evidence of safety,  establishing  that it will reasonably be expected
to be safe,  such evidence to be provided by the  manufacturer or distributor to
FDA at least 75 days before  commencing  to market  such a product.  Among other
changes,  the new law prevents the further regulation of dietary  ingredients as
"food   additives"   and   establishes   a  commission   to  study  and  provide
recommendations  for the  regulation of label claims and  statements for dietary
supplements,  including the use of literature in connection with sale of dietary
supplements and procedures for the evaluation of such claims.

   Pursuant  to the new  law,  the  FDA has  published  notices  in the  Federal
Register  asking  for  public  comments  on  proposals  for   implementing   the
requirements  of the  legislation.  These proposals would require changes in the
Company's labeling for its products,  but the regulations are not yet in effect.
Consequently,  the FDA has  not  finally  reconciled  its  existing  enforcement
practice with the new legislation described above.  Businesses in this industry,
including the Company,  are introducing various products in reliance on industry
interpretations  of the law, which  interpretations  have not yet been proven or
judicially tested.

   Therefore,  the Company cannot  determine to what extent any new,  changed or
amended  regulations or enforcement  practices,  when and if  implemented,  will
affect its business. Such actions could, among other things, require expanded or
different labeling, the recall or discontinuance of certain products, additional
record keeping and expanded documentation of the properties of certain products,
and more complete scientific  substantiation.  For example,  the new legislation
requires that dietary  supplements  be  manufactured  in  accordance  with "Good
Manufacturing Practices." The FDA has not yet identified what
                                       33
<PAGE>
the specific  practices will be. The Good  Manufacturing  Practices  requirement
will affect the businesses who supply  finished  dosage products to the Company.
If  the  Company  implements  its  plans  to  undertake  its  own  manufacturing
operations, the Company will also be required to comply with these manufacturing
practices.

   
   Although  the full  aspects of the FDA's  labeling  requirements  for dietary
supplements have not yet been clearly  established,  the regulations proposed in
December  of 1995 and  expected  to  become  final  later in 1996,  do  indicate
pursuant to the new statutory  provisions the general types of changes which the
Company will be required to make. These  modifications  will apply to all of the
Company's products,  and will include revised labeling to incorporate  necessary
statements and disclosures  (identification of product as a "dietary supplement"
and. where applicable, adding a notice "This statement [about an efficacy claim]
has not been evaluated by the Food and Drug Administration.  This product is not
intended to diagnose,  treat, cure, or prevent any disease".  After the labeling
changes are made,  the Company will also provide  formal  notice to the FDA that
such  statements  have been  placed on the label of a  product.  As part of this
process,  the Company will also generally review its product line for compliance
with  technical  requirements  such as type size,  sufficiency of declaration of
ingredients,  as well as for the sufficiency of  substantiation  for any product
claims.  The Company estimates that the cost of making the label changes will be
approximately  $35,000.  The FDA's final regulations are expected in December of
1996, and the FDA has informally stated that it will, subject to public comment,
withhold enforcement of the regulations until January 1, 1998. Accordingly,  the
Company  expects  that it will be required to  implement  the  labeling  changes
during the course of 1997. 
    

   Similarly,  marketing  and  sale of  dietary  supplements  is to some  extent
dependent on avoiding a drug  classification for such products.  The FDA has not
yet delineated how the drug versus dietary supplement will be made under the new
law.  Classification as a drug and potentially as a "new drug" might prevent the
Company from continuing to sell, or from introducing  certain types of products.
Some of the  Company's  products may be regulated  separately  as foods  without
invoking the provisions of the law applicable to dietary  supplements.  This may
also require label changes to conform to FDA's separate food regulations.

   Separate and apart from FDA  regulations  and  enforcement,  the  promotional
activities  of the Company are also subject to  regulation by the FTC and to the
extent of the use of the  mails,  by the United  States  Postal  Service.  These
agencies  impact  on the  Company's  activities  primarily  in the  areas of the
requirements for "truth in advertising." The Company's business is in large part
based upon the  popularization  of products and ingredients for which there have
been reports in the lay or scientific literature as to their usefulness in human
nutrition  and  health.  These  reports  are  often  preliminary,  and  are  not
necessarily  supported and  documented by the types of scientific  studies which
would  satisfy  the FTC and  FDA.  The FTC has  recently  commenced  proceedings
against other businesses in the health food industry challenging the sufficiency
of their  "substantiation"  in support of specific product  marketing claims. As
FDA moves forward to finalize the  regulations  under DSHEA, it is expected that
the FTC, which to some extent works cooperatively with FDA, may also step up its
enforcement   activities  with  regard  to   substantiation   requirements   for
promotional  claims.  There is therefore  no assurance  that the Company will be
able to continue  making the types of promotional  claims which have  previously
characterized the Company's marketing efforts.

   The management of the Company  believes that it is in substantial  compliance
with existing regulatory and enforcement  requirements,  taking into account the
manner in which other  companies  market and  promote  their  products,  and the
present pattern of enforcement  activities by the respective  agencies discussed
above.  There is no  assurance  that the  present  enforcement  policies  of the
regulatory  agencies will continue either in general, or specifically as regards
the Company.  Company  management  expects that the regulatory  and  enforcement
requirements  will to some extent  become more  stringent,  and that the Company
will have to adapt its marketing and promotional activities accordingly.  All or
any  of the  change  which  will  be  required  in the  Company's  labeling  and
promotional  activities  could have a material  adverse  effect on the Company's
business,  financial  condition and results of operations.  See "Risk Factors --
Absence of Clinical Studies, Scientific Review and Testing," "-- Uncertainty and
Potential Negative Effect of Government Regulations" and "-- Non-Compliance with
Government Regulations."
                                       34
<PAGE>
   
   Government  regulations in foreign  countries,  where the Company may wish to
commence sales,  may also prevent or delay entry into such markets.  The Company
has not yet studied the requirements of regulations in foreign countries as they
may apply to the Company's products.  The Company may be required to reformulate
or  otherwise  adapt its  products in order to comply with the  requirements  of
foreign  countries.  Some foreign  countries  may prohibit the sales of products
which the Company  sells in the United  States.  There is no assurance  that the
Company  will be able to comply  with the  applicable  requirements  of  foreign
countries. 
    

EMPLOYEES

   
   As of August 15, 1996,  the Company had 26 employees,  19 of whom were leased
through a professional employer organization ("PEO"), Employee Solutions,  Inc.,
of which Harvey Belfer, a director and consultant to the Company, is a director.
See "Management -- Executive Officers and Directors" and "Certain Transactions."
Through  this  arrangement,  the Company pays a fee of  approximately  3% of the
employees'  salary for the PEO to be the employer of record for these  full-time
Company employees, thus easing the Company's payroll and benefits administration
burden. The Company intends to terminate this leasing arrangement by early 1997.
Six of the Company's  employees are in sales,  seven in shipping and  receiving,
three in accounting, two in advertising and public relations and two in consumer
service. The remainder of the Company's employees, including the officers, serve
general  and  administrative  functions.  None of the  Company's  employees  are
covered by a collective bargaining agreement. 
    

FACILITIES

   In October  1995,  the Company  moved into a 14,000 square foot leased office
and warehouse facility in Tempe, Arizona. Management believes that this facility
provides sufficient space for the Company's current operations,  but anticipates
that  additional  space will be needed during fiscal 1997.  See "Risk Factors --
Limited  Capitalization."  The Company  believes that additional  suitable space
will be available on commercially  reasonable  terms.  The lease currently calls
for  monthly  rent of $6,941,  increasing  to $7,288 in August  1997,  $7,652 in
August 1998 and $8,035 in August 1999, and expires on July 31, 2000. The Company
also intends to establish a 10,000 square foot manufacturing facility by the end
of the fiscal year. See "Use of Proceeds."

TRADE ASSOCIATIONS

   The Company belongs to a number of trade associations, including the American
Botanical Council, the American Herbal Products  Association,  the Herb Research
Foundation, the Canadian Health Food Association, the World Watch Institute, and
the National Nutritional Foods Association, and is a contributor to Citizens for
Health.

LITIGATION

   
   The Company has  received  correspondence  from an overseas  trading  company
threatening  to  institute  litigation  in Japan based on  allegations  that the
Company  breached a contract with the trading company by failing to designate it
the  exclusive  distributor  of  Citrium(TM)  in Japan.  The trading  company is
claiming  damages of  $500,000.  To the  knowledge of the Company no lawsuit has
been filed or served in this matter at this time.  The Company is in the initial
stages of reviewing the  allegations,  and it will take  appropriate  responsive
measures if a complaint is filed. See Note 4 of Notes to Unaudited  Consolidated
Financial Statements for the three months ended August 31, 1996.

   The executive officer named in the Summary  Compensation Table did not own or

"Description  of Capital  Stock --  Warrants"  and  "Certain  Transactions"  for
information  regarding  warrants  received by Mr.  Nikzad during fiscal 1996. On
June 1, 1996, the Company adopted a plan pursuant to which the Company may grant
options to purchase Common Stock to employees,  including officers,  and others.
On June 1, 1996,  the Company  granted Mr.  Nikzad an option to purchase  30,000
shares at $3.50 per share under the Stock Option Plan. See  "Management -- Stock
Option Plan." 
    

STOCK OPTION PLAN

   
   The Company's 1996 Stock Option Plan (the "Stock Option Plan") was adopted by
the  Board  of  Directors  in June  1996 and  approved  by the  stockholders  in
September 1996 to grant options to purchase  300,000 shares of Common stock.  As
of August 15,  1996,  options to purchase  228,000  shares of Common  Stock were
outstanding.  The Stock  Option Plan  provides  for the granting to employees of
either  "incentive  stock  options"  within the  meaning  of Section  422 of the
Internal  Revenue Code of 1986, as amended (the "Code"),  or nonqualified  stock
options to any  individual,  including  employees  and directors of the Company.
Incentive  stock options may be granted only to employees,  including  officers.
The exercise  price of incentive  stock  options  granted under the Stock Option
Plan must be the fair market value of the Common Stock on the date of grant. The
exercise  price  of any  incentive  stock  option  granted  to an  optionee  who
beneficially  owns more than 10% (a "10% Holder") of the Company's  voting stock
must be at least 110% of the fair market value of the  underlying  shares on the
date of grant.  The Stock  Option Plan expires in 2006 with respect to incentive
stock options.
    

   Under the Stock Option Plan, nonqualified stock options may be granted to any
individual,  including  employees  and  directors  and  consultants  who are not
employees of the Company.  The exercise price of nonqualified  stock options may
be any amount  determined in good faith by the Board of Directors or a committee
appointed  by the Board.  The Company has no plans to grant  nonqualified  stock
options  at an  exercise  price  of less  than  the  fair  market  value  of the
underlying shares on the date of grant.

   The Stock  Option  Plan is  administered  by the full Board of  Directors  or
compensation  committee  of  the  Board  (the  "Compensation  Committee")  which
determines the terms of options  granted under the Stock Option Plan,  including
the  exercise  price and the number of shares  subject to the option.  The Stock
Option Plan provides the Compensation Committee with the discretion to determine
when options granted thereunder shall become  exercisable.  Most options granted
under the Stock Option Plan become  exercisable over a period of three years and
have a term of five years. No option may be exercised more than 10 years (or, in
the case of an incentive  option granted to a 10% Holder,  more than five years)
after its grant  date.  Options  granted  under  the Stock  Option  Plan are not
transferable by the optionee after the date of its grant.  Options granted under
the Stock Option Plan are not transferable by the optionee other than by will or
the laws of descent and distribution,  and each option is exercisable during the
lifetime  of  the  optionee  only  by  the  optionee,   his  guardian  or  legal
representative.  Incentive stock options held by employees of the Company may be
exercised by the  participant  only while  employed by the Company or within one
year  following  termination  resulting  from death or permanent  disability  or
within three months after termination for any reason other than cause,  death or
permanent disability, or on or before the date
                                       38
<PAGE>
the  participant's  employment  with the  Company is  terminated,  if for cause.
Options  to  non-employees  may be  exercised  within  such  time  period as the
Compensation  Committee  determines  but no later than 10 years from the date of
grant, two years after cessation of services to the Company for any reason other
than  death,  permanent  disability,  retirement  or cause,  three  years  after
cessation of services by reason of death,  permanent disability or cause, or the
date of  cessation  of services for cause.  Upon the  occurrence  of a change in
control of the Company,  100% of all unvested  options that had been outstanding
for at least six months will vest.

EMPLOYMENT CONTRACTS, TERMINATION OF EMPLOYMENT, AND CHANGE-IN-CONTROL
ARRANGEMENTS

   
   Hooman Nikzad entered into a three-year employment agreement with the Company
as of June 1,  1996,  pursuant  to which  he was  employed  as  Chief  Executive
Officer. Under the agreement, Mr. Nikzad is entitled to an annual base salary of
$85,000,  increasing by 10% annually  commencing May 31, 1997. Unless terminated
without cause, Mr. Nikzad is entitled to a lump sum payment equal to the greater
of the base salary due for the remainder of the term of the employment agreement
or 12 months' base salary,  and continuation of coverage under medical plans for
up to 12  months.  Mr.  Nikzad is  entitled  to certain  incentive  compensation
payments,  if any, made for the year of  termination of his employment for death
or disability.  If the  employment is terminated  within 12 months after certain
changes in control of the Company,  Mr. Nikzad is entitled to a lump sum payment
(in lieu of the payment  referred to in the second  preceding  sentence)  not to
exceed  2.99  times the base  amount  defined in  Section  280G of the  Internal
Revenue Code of 1986, as amended, continuation of medical coverage for 12 months
and  other  benefits  in  effect  at that  time.  The  agreement  also  contains
confidentiality  and  non-competition  covenants.  These covenants might be held
unenforceable  or only  partially  enforceable  if  challenged  in a  court.  In
connection with his employment, Mr. Nikzad received options for 30,000 shares of
the Company's Common Stock on June 1, 1996,  exercisable at $3.50 and vesting in
equal parts on the first three anniversaries of the grant date. 
    

   The Company has similar agreements with Messrs. Todd Belfer,  Djahandideh and
Denton employing them in their  capacities as officers with the Company,  except
that their annual salary is $50,000, $85,000 and $65,000,  respectively, and the
numbers of options received were 30,000, 30,000 and 10,000,  respectively.  Todd
Belfer's salary is $50,000 per annum, increasing 10% annually commencing May 31,
1997,  and Mr.  Denton's  salary is  $65,000  per annum,  increasing  to $70,000
January 1, 1997 and to $75,000  January 1, 1998,  with provisions for Mr. Denton
to receive annual bonuses of $10,000,  $15,000 and $20,000 for fiscal years 1997
through 1999, respectively,  should the Company achieve net sales targets during
such  years.  In  connection  with his  employment,  Mr.  Denton  also  received
five-year  warrants  exercisable for 60,000 and 30,000 shares of Common Stock at
an exercise  price of $.50 and $1.00,  respectively,  vesting in stages  through
December 31, 1998.

                              CERTAIN TRANSACTIONS

   The Company's  predecessor,  Houston,  was founded by Hooman Nikzad,  Todd P.
Belfer,  Fred Djahandideh,  Harvey A. Belfer and Marvin D. Brody.  Houston was a
party to an agreement  dated December 12, 1995 pursuant to which Marvin D. Brody
and Nancy P. Brody transferred their Houston  membership  interests to Harvey A.
Belfer, Todd P. Belfer, Hooman Nikzad and Fradjollah  Djahandideh.  Houston paid
approximately  $4,100 in attorneys' fees relating to the agreement and agreed to
indemnify the sellers against all liabilities arising from Houston's operations.

   
   In May 1996,  Messrs.  Nikzad,  Todd Belfer,  Djahandideh  and Harvey  Belfer
completed a private  placement of portions of their membership  interests in the
Company's predecessor,  Houston, selling approximately 16.6% of their interests.
The Company did not receive any proceeds  from the sale.  On May 31,  1996,  all
members  converted  their  interests into shares of the Company's  Common Stock.
Private  placement  costs  associated  with the  transactions  of  approximately
$70,000 were paid by the  Company.  In  connection  with the  transactions,  the
Company  also issued  warrants to purchase  an  aggregate  of 118,421  shares of
Common  Stock to the  underwriter  of a portion  of the  private  placement  and
entities  associated  with an attorney  involved in the private  placement and a
director of the Company who subsequently  resigned.  See "Description of Capital
Stock -- Warrants."
    

   Houston made limited liability company  distribution  payments to its members
in fiscal 1995 and fiscal  1996,  including  the  following  payments to current
executive officers and directors:  Mr. Nikzad,  $125,256 in 1995 and $220,313 in
1996; Mr. Todd Belfer,  $125,256 in 1995 and $220,313 in 1996; Mr.  Djahandideh,
$224,339 in 1995 and $495,313 in 1996; and Mr. Harvey  Belfer,  $112,966 in 1995
and $264,063 in 1996. The Company succeeded to Houston's  business effective May
31, 1996 and no additional  distributions  will be made. See "Limited  Liability
Company  Distributions" and Consolidated  Statements of Shareholders' Equity and
Notes to Consolidated Financial Statements.

   The Company  currently leases 19 of its employees through an employee leasing
company, Employee Solutions, Inc. ("ESI"), of which Harvey Belfer was co-founder
and Chief  Executive  Officer,  and is a  Director,  and for which  Todd  Belfer
previously  served as Director  and Vice  President  of  Marketing  and Investor
Relations.  For the  years  ended  May 31,  1996  and  1995,  Houston  paid  ESI
approximately  $923,000 and  $506,000,  respectively,  for employee  leasing and
related expenses.

   
   From February 1994 to October 1994,  Houston retained the services of Propay,
Inc., an employee  leasing firm ("Propay"),  which Hooman Nikzad  co-founded and
sold to ESI in October 1993. For the fiscal year ended May 31, 1995, the Company
paid Propay approximately $329,000 for such employee leasing services. 
    

   During  fiscal  1995,  Houston  paid a total  of  approximately  $353,600  in
consulting  and  other  fees to Pure  Source  Ltd.,  a  British  Virgin  Islands
corporation ("Pure Source") which provided  marketing,  purchasing,  promotional
and other international advertising services and assisted in locating sources of
raw materials. On December 31, 1995, the consulting agreement was terminated. No
fees were paid to Pure Source in fiscal 1996. All of the members of Houston, the
predecessor  to the  Company,  had  beneficial  interests  in  Pure  Source  and
benefitted  from the  payment  of such fees.  Current  directors  and  executive
officers of the Company held the following  ownership  interests in Pure Source:
Mr. Todd  Belfer,  15%;  Mr.  Nikzad,  15%;  Mr.  Harvey  Belfer,  17.5% and Mr.
Djahandideh, 35%.

   In February  1996,  the Company  purchased  all of the  outstanding  stock of
Belnik Investment Group, Inc., an Arizona  corporation doing business as Freedom
Wholesalers, Inc. ("Freedom"), from Messrs. Nikzad and Todd Belfer. The purchase
price  consisted of $1,000 plus  warrants  issued to each of Messrs.  Nikzad and
Todd Belfer to purchase 10,500 shares of the Company's Common Stock  exercisable
at $1.00 per share and vesting in three  equal  annual  installments  commencing
December 31, 1996. Prior to acquiring Freedom, the Company had been distributing
certain of its  products  through  Freedom as well as  providing  office  space,
telephone  facilities,  other business  services,  and management to Freedom for
which  Freedom  reimbursed  the Company  $190,291 in fiscal 1995 and $437,310 in
fiscal 1996.  See "Business -- Products" and "-Freedom  Products." For financial
reporting  purposes,  the  operations  of  Freedom  are  consolidated,  and  all
intercompany  balances  and  transactions  are  eliminated.  See  Note  2 to the
Consolidated Financial Statements.

   On March 6, 1996,  the  Company  borrowed  $300,000  from Belfer Labs LLC, an
affiliated company formed by Todd Belfer, President and Director of the Company,
and Harvey  Belfer,  father of Todd Belfer and  consultant  and  Director of the
Company.  The Belfer Labs Note accrues interest at the rate of 12% per annum, is
payable  March  6,  1997  and  is  collateralized  by  substantially  all of the
Company's  assets.  The proceeds of the Belfer Labs Note were distributed to the
members of Houston for,  among other things,  the members' tax  liability  which
resulted  from the  profitable  operations of the Company prior to the Company's
conversion  to a  corporation.  On July 23, 1996,  the Company paid  $100,000 in
principal on the note plus accrued interest of $14,100.  Management  anticipates
repaying the remaining  balance  payable on the note with the proceeds from this
Offering.

   The Company  believes  that the terms of the ongoing  transactions  described
above are fair,  reasonable and consistent with the terms that the Company could
obtain from unaffiliated  third parties.  The Company has no plans to enter into
any additional  transactions  with officers,  directors or  stockholders  of the
Company.  In  the  future,  the  Company  will  not  engage  in  any  additional
transactions with its officers, directors or 5% stockholders or their affiliates
unless the transaction is approved by a majority of the disinterested  directors
of the Company after full  disclosure  and will be on terms no less favorable to
the Company than would be available from an unaffiliated third party.

                          DESCRIPTION OF CAPITAL STOCK

   The authorized  capital stock of the Company  consists of 8,000,000 shares of
Common Stock,  $.001 par value per share, and 100,000 shares of Preferred Stock,
$.01 par value per share  (the  "Preferred  Stock"),  issuable  in  series.  The
following summary of certain  provisions of the Company's capital stock does not
purport to be complete and is subject to, and  qualified in its entirety by, the
provisions of the Company's Certificate of Incorporation (the "Certificate") and
Bylaws  which are  included as exhibits to the  Registration  Statement of which
this Prospectus is a part, and by the provisions of applicable law.

COMMON STOCK

   Immediately  prior to the  Offering,  there were  3,000,000  shares of Common
Stock outstanding  which were held of record by 39 stockholders.  The holders of
Common  Stock are entitled to one vote per share on all matters to be voted upon
by the  stockholders.  Stockholders are not entitled to cumulate their votes for
the election of directors.  Subject to preferences that may be applicable to any
outstanding  shares of Preferred Stock, the holders of Common Stock are entitled
to receive such dividends pro rata, if any, as may be declared from time to time
by the Board of Directors out of funds legally  available for that purpose.  See
"Dividend  Policy." In the event of a liquidation,  dissolution or winding up of
the  Company,  the holders of Common Stock are entitled to share pro rata in all
assets  remaining  after payment of liabilities,  subject to prior  distribution
rights of Preferred  Stock,  if any, then  outstanding.  The Common Stock has no
preemptive  or  conversion  rights or other  subscription  rights.  There are no
redemption  or sinking  fund  provisions  applicable  to the Common  Stock.  All
outstanding  shares of Common  Stock are fully paid and  nonassessable,  and the
shares of Common Stock to be issued upon  completion  of this  Offering  will be
fully paid and nonassessable.

PREFERRED STOCK

   The Company is authorized to issue 100,000 shares of  undesignated  Preferred
Stock.  The Board of  Directors  has the  authority  to issue  the  undesignated
Preferred  Stock in one or more series and to determine the powers,  preferences
and rights and the  qualifications,  limitations or  restrictions  granted to or
imposed upon any wholly unissued  series of undesignated  Preferred Stock and to
fix the number of shares  constituting  any series and the  designation  of such
series,  without  any  further  vote or  action by the  stockholders.  Shares of
Preferred  Stock  so  designated  may  have  voting,   conversion,   liquidation
preference,  redemption,  sinking  fund  provisions  and other  rights which are
superior to those of the Common Stock.  The issuance of Preferred Stock may have
the  effect of  delaying,  deferring  or  preventing  a change in control of the
Company without further action by the stockholders,  may discourage bids for the
Common  Stock at a premium  over the market  price of the  Common  Stock and may
adversely  affect  the market  price of and the  voting and other  rights of the
holders of Common  Stock.  At  present,  the  Company  has no plans to issue any
shares of the Preferred Stock.

WARRANTS

   
   As of August 31,  1996,  the  Company  has  outstanding  warrants to purchase
464,421  shares of its Common  Stock,  of which  276,149  were  exercisable,  as
further  described  below.  Each  warrant  expires  in either  May or June 2001,
respectively,  and contains  provisions for the adjustment of the exercise price
and the aggregate  number of shares  issuable upon exercise of the warrant under
certain circumstances, including stock dividends, stock splits, reorganizations,
reclassifications  and consolidations,  and in certain cases, for dilutive sales
of Common Stock below the then existing  exercise  price.  Certain  warrants are
entitled  to  registration   rights.   See  "Description  of  Capital  Stock  --
Registration Rights."

   Of the warrants referred to in the preceding paragraph,  warrants to purchase
60,000 shares are exercisable at $.50 per share, vesting in stages through 1999.
Warrants to purchase  51,000 shares are exercisable at $1.00 per share, of which
10,000  warrants  are  vested,  and the  balance  vest in stages  through  1998.
Warrants to purchase 192,656 shares are exercisable at $3.50 per share, of which
107,656 are vested  currently,  and the balance vest in stages through 1999. Two
warrants to purchase  75,000 shares each are exercisable at $5.00 and $10.00 per
share,  respectively,  all of which are vested  currently.  Warrants to purchase
10,765  shares  are  exercisable  at the price at which  shares are sold in this
Offering, all of which warrants are vested.
    
                                       43
<PAGE>
   
   In September  1996, the Company granted  warrants to purchase  100,000 shares
and 14,000  shares to a Company  director/consultant  and a paid endorser of the
Company's  products,  respectively.  The warrants to purchase 100,000 shares are
exercisable  at $7.00 per share and vest  pro-rata,  on a daily basis,  over the
year  ending  July  31,  1997.  The  warrants  to  purchase  14,000  shares  are
exercisable  at $6.00 per share,  and vest as to 7,000 shares on each  September
14, 1997 and September 14, 1998. 
    

CERTAIN ANTI-TAKEOVER PROVISIONS

   Stockholders'  rights and related matters are governed by Delaware  corporate
law, the  Certificate  and Bylaws.  Certain  provisions of the  Certificate  and
Bylaws that are summarized below may affect potential  changes in control of the
Company.  The  cumulative  effect  of  these  provisions  may be to make it more
difficult to acquire and exercise  control of the Company and to make changes in
management.

   The affirmative vote of at least two-thirds of the shares entitled to vote is
required for a merger or a  consolidation  with, or a sale by the Company of all
or substantially all of its assets to, any person,  firm or corporation,  or any
group thereof,  which owns,  directly or indirectly,  5% or more of any class of
voting securities of the Company, exclusive of any person holding 10% or more at
May 31, 1996 (an  "Interested  Person").  In  addition,  two-thirds  approval is
required with respect to other  transactions  involving any  Interested  Person,
including  the  purchase  by the  Company or any of its  subsidiaries  of all or
substantially  all of the assets or stock of an Interested  Person and any other
transaction with an Interested Person that requires  stockholder  approval under
Delaware  law.  The  two-thirds  voting  requirement  is  not  applicable  to  a
transaction  that is  approved  by the Board of  Directors  if a majority of the
members  of the Board of  Directors  voting to  approve  such  transaction  were
elected prior to the date on which the other party became an  Interested  Person
(the "Continuing  Directors") or whose initial election as a director succeeds a
Continuing  Director  or  fills a newly  created  directorship  approved  by the
Continuing Directors.

   Commencing with the 1997 annual meeting of  stockholders,  each director will
serve for a three-year term and approximately one-third of the directors will be
elected  annually.  Candidates for election of directors shall be nominated only
by the Board of Directors or by a stockholder  who gives prior written notice to
the Company,  generally not less than 60 nor more than 90 days before the annual
meeting. The Company may have three to nine directors as determined from time to
time by the Board, which currently consists of six members.  Between stockholder
meetings, the Board may appoint new directors to fill vacancies or newly created
directorships.  The  Certificate  does not  provide  for  cumulative  voting  at
stockholder  meetings for election of directors.  Stockholders  controlling more
than  50% of the  outstanding  Common  Stock  can  elect  the  entire  Board  of
Directors,  while  stockholders  controlling  less  than 50% of the  outstanding
Common Stock may not be able to elect any  directors.  A director may be removed
from office only for cause by the affirmative vote of a majority of the combined
voting power of the then outstanding  shares of stock entitled to vote generally
in the election of directors.

   The Certificate  further provides that stockholder  action must be taken at a
meeting of  stockholders  and may not be effected  by any consent in writing.  A
special meeting of stockholders may be called only by the Chairman of the Board,
the Chief  Executive  Officer,  a majority of the whole Board of Directors or by
the  holders of at least 25% of the Common  Stock.  If a  stockholder  wishes to
propose  an agenda  item for  consideration  at a  meeting  he must give a brief
description  of each item and written notice to the Company not less than 60 nor
more than 90 days prior to the meeting or such other period of time necessary to
comply with applicable  federal proxy  solicitation  rules or other regulations.
Stockholders  may need to present  their  proposals or director  nominations  in
advance of the time they  receive  notice of the meeting  because the  Company's
Bylaws  provide  that notice of a  stockholders'  meeting must be given not less
than 10 or more than 60 days prior to the meeting date.

   The  Certificate  provides  further  that  the  foregoing  provisions  of the
Certificate and Bylaws may be amended or repealed only with the affirmative vote
of at least  two-thirds of the shares entitled to vote,  unless the amendment is
recommended for stockholder approval by a majority of the Continuing  Directors.
These provisions  exceed the usual majority vote requirement of Delaware law and
are intended to prevent the holders of less than  two-thirds of the voting power
from  circumventing  the foregoing  terms by amending the Certificate or Bylaws.
These  provisions,  however,  enable the holders of more than  one-third  of the
voting power to prevent  amendments  to the  Certificate  or Bylaws even if they
were favored by the holders of a majority of the voting power.
                                       44
<PAGE>
   The  effect  of  these   provisions   may  be  to  make  more  difficult  the
accomplishment  of a merger  or other  takeover  or  change  in  control  of the
Company.  To the extent that these  provisions have this effect,  removal of the
Company's  incumbent  Board of Directors  and  management  may be rendered  more
difficult.  Furthermore,  these  provisions  may  make  it  more  difficult  for
stockholders  to  participate in a tender or exchange offer for Common Stock and
in so doing may diminish the market value of the Common Stock.

PERSONAL LIABILITY OF DIRECTORS

   
   Delaware  law  authorizes  a Delaware  corporation  to eliminate or limit the
personal  liability of a director to the  corporation and its  stockholders  for
monetary  damages  for breach of certain  fiduciary  duties as a  director.  The
Company believes that such a provision is beneficial in attracting and retaining
qualified  directors,  and  accordingly,  the  Certificate  includes a provision
eliminating liability for monetary damages for any breach of fiduciary duty as a
director, except (i) for any breach of the duty of loyalty to the Company or its
stockholders;  (ii) for acts or  omissions  not in good  faith or which  involve
intentional  misconduct or a knowing violation of law; (iii) for any transaction
from  which the  director  derived an  improper  personal  benefit;  or (iv) for
unlawful  payments of dividends or unlawful  stock  repurchase or redemptions as
provided in Section 174 of the Delaware General  Corporation Law.  Directors are
not insulated  from  liability for breach of their duty of loyalty or for claims
arising  under the federal  securities  laws.  The  foregoing  provisions of the
Certificate may reduce the likelihood of derivative litigation against directors
for  breaches  of  their  fiduciary  duties,  even  though  such an  action,  if
successful,  might otherwise have  benefitted the Company and its  stockholders.
Furthermore,  the Company has entered into indemnity  agreements with all of its
directors and officers for the  indemnification  of and advancing of expenses to
such persons to the fullest  extent  permitted  by law.  The Company  intends to
execute such indemnity  agreements with its future  officers and directors.  The
Company is in the process of  obtaining  comprehensive  directors  and  officers
liability insurance coverage, and anticipates obtaining an insurance policy with
an  aggregate  policy limit of not less than  $3,000,000  for the benefit of its
officers and  directors  insuring  such  persons  against  certain  liabilities,
including  liabilities  under the  securities  laws, no later than the effective
date of this Offering.  Insofar as indemnification for liabilities arising under
the Securities Act of 1933, as amended (the  "Securities  Act") may be permitted
to directors,  officers and controlling  persons of the Company  pursuant to the
foregoing  provisions,  or  otherwise,  the Company has been advised that in the
opinion of the SEC such indemnification is against public policy as expressed in
the Securities Act and is, therefore, unenforceable.
    

DELAWARE LAW

   The  Company is  subject to the  provisions  of Section  203 of the  Delaware
General  Corporation  Law. In general,  this statute  prohibits a publicly  held
Delaware  corporation  from  engaging  in  a  "business   combination"  with  an
"interested  stockholder"  for a period of three  years  after the date that the
person became an interested  stockholder  unless (with certain  exceptions)  the
business combination or the transaction in which the person became an interested
stockholder  is  approved  in  a  prescribed  manner.   Generally,  a  "business
combination"  includes  a  merger,  asset or stock  sale,  or other  transaction
resulting in a financial benefit to the stockholder.  Generally,  an "interested
stockholder" is a person who, together with affiliates and associates,  owns (or
within  three  years  prior,  did own) 15% or more of the  corporation's  voting
stock.

REGISTRATION RIGHTS

   
   Holders of 498,375  shares of Common Stock and holders of warrants to acquire
257,656  shares of Common Stock have the right to demand  registration  of up to
50% of such shares commencing  September 1, 1997 and also will have the right to
receive  notice of proposed  registrations  of  securities by the Company and to
cause  the  Company  to  include  all  or a  portion  of  such  shares  in  such
registrations at the Company's expense,  provided, among other conditions,  that
the  underwriters  of any such offering shall have the right to limit the number
of shares included in such  registration.  The holders of these shares of Common
Stock are all of the  Company's  current  stockholders  other than the Company's
directors, officers
    
                                       45
<PAGE>
   
and certain members of their  respective  immediate  families.  Holders of these
warrants are: Canyon  Security,  L.L.C.,  an Arizona limited  liability  company
which is associated with an attorney involved in the Company's private placement
of May 31,  1996.  JBV  Investments,  L.C.,  a Utah  limited  liability  company
associated with a former director of the Company; and Michael J. Dwyer, a broker
who  has  invested  in  the  Company  in his  individual  capacity.  Holders  of
applicable registration rights relating to this Offering have been notified that
their  respective  shares will not be included in this Offering.  The Company is
obligated to pay the  offering  expenses of each such  offering,  except for the
selling   stockholders'   pro  rata  portion  of   underwriting   discounts  and
commissions. 
    

   Prior to this Offering,  there has been no market for the Common Stock and no
precise  prediction  can be made of the effect,  if any,  that  market  sales of
shares or the  availability  of shares  for sale will have on the  market  price
prevailing from time to time. Nevertheless,  sales of substantial amounts of the
Common  Stock in the public  market could  adversely  affect  prevailing  market
prices.

TRANSFER AGENT AND REGISTRAR

   The Company has appointed Corporate Stock Transfer, Inc., Denver, Colorado as
the transfer agent and registrar for the Company's Common Stock.
                                       46
<PAGE>
                         SHARES ELIGIBLE FOR FUTURE SALE

   Upon completion of this Offering,  the Company will have 4,300,000  shares of
Common Stock outstanding.  Of these shares, 1,300,000 of the shares sold in this
Offering (plus any additional shares sold upon the exercise of the Underwriters'
Over-allotment  Option) will be freely  tradable under the Securities Act except
for shares  purchased by  "affiliates"  of the Company within the meaning of the
rules and regulations under the Securities Act.

   The remaining 3,000,000 outstanding shares (the "Restricted  Shares"),  which
were  issued  by the  Company  on May 31,  1996 in  reliance  upon the  "private
placement"  exemption  provided by Section 4(2) of the  Securities  Act, will be
deemed restricted securities within the meaning of Rule 144 under the Securities
Act.  Restricted  Shares may not be sold  unless they are  registered  under the
Securities   Act  or  are  sold  pursuant  to  an  applicable   exemption   from
registration, including an exemption under Rule 144.

   In general,  under Rule 144 of the  Securities  Act as  currently  in effect,
beginning 90 days after the date of this Prospectus,  a person (or persons whose
shares are aggregated) who has beneficially owned "restricted securities" for at
least two years  (one year under  currently  proposed  amendments  to Rule 144),
including a person who may be deemed an affiliate of the Company, is entitled to
sell within any three-month  period a number of shares of Common Stock that does
not exceed the greater of 1% of the then  outstanding  shares of Common Stock of
the Company (43,000 shares after giving effect to this Offering) and the average
weekly trading volume of the Common Stock on the Nasdaq  National  Market during
the four  calendar  weeks  preceding  such  sale.  Sales  under  Rule 144 of the
Securities Act are subject to certain  restrictions  relating to manner of sale,
notice and the availability of current public  information about the Company.  A
person who is not an  affiliate  of the  Company at any time  during the 90 days
preceding a sale, and who has beneficially owned shares for at least three years
(two years under currently  proposed  amendments to Rule 144), would be entitled
to sell such shares  without  regard to the volume  limitations,  manner of sale
provisions or notice or other  requirements  of Rule 144 of the Securities  Act.
However,  the  transfer  agent may require an opinion of counsel that a proposed
sale of shares comes within the terms of Rule 144 of the Securities Act prior to
effecting a transfer of such shares.

   
   The Company and its officers and directors holding  an aggregate of 2,324,625
shares of Common Stock have entered into lockup agreements with the Underwriters
pursuant to which such stockholders have agreed not to sell or otherwise dispose
of any  shares of Common  Stock for a period of 180 days  after the date of this
Prospectus   without  the  prior  written  consent  of  the  Underwriters.   See
"Underwriting."

   After the  expiration of the lockup  agreements  with the  Underwriters,  the
Company  expects  to  file a  Registration  Statement  on  Form  S-8  under  the
Securities  Act to  register  all of the  shares of Common  Stock  reserved  for
issuance under the Company's 1996 Stock Option Plan. After the effective date of
such Registration  Statement,  shares purchased upon exercise of options granted
pursuant to the Stock Option Plan generally would be available for resale in the
public  market.  As of August 31, 1996,  options to purchase  228,000  shares of
Common  Stock were  outstanding,  none of which were  exercisable.  To date,  no
options have been exercised.
    

   Following  completion of this  offering,  holders of 498,375 shares of Common
Stock and the holders of warrants to acquire 257,656 shares of Common Stock have
the right,  under  certain  conditions,  to cause the Company to  register  such
shares  under  the   Securities   Act  and  to  participate  in  future  Company
registrations. See "Description of Capital Stock -- Registration Rights."

   Prior to this Offering, there has been no market for the Common Stock, and no
precise  prediction  can be made of the effect,  if any,  that  market  sales of
shares or the  availability  of shares  for sale will have on the  market  price
prevailing from time to time. Nevertheless,  sales of substantial amounts of the
Common  Stock in the public  market could  adversely  affect  prevailing  market
prices and limit the Company's ability to raise additional capital.

   The  Underwriters  named below,  for whom Sentra  Securities  Corporation and
Spelman  &  Co.,   Inc.   are   acting   as   representatives   (together,   the
"Representatives"),  have severally agreed,  subject to the terms and conditions
of the Underwriting Agreement, to purchase from the Company the number of shares
set forth opposite their names.

                                                            =========

   
   The Company is  obligated  to sell,  and the  Underwriters  are  obligated to
purchase all of the shares of Common Stock offered  hereby if any are purchased.
The  Company  has been  advised  by the  Representatives  that the  Underwriters
propose to offer the Common Stock  purchased  by them  directly to the public at
the public  offering price set forth on the cover page of this Prospectus and to
certain  dealers at a price that  represents  a concession  of $             per
share. The  Underwriters  may allow, and such dealers may reallow,  a concession
within the discretion of the Representatives.  After the initial public offering
of the Common Stock,  the offering price and the selling terms may be changed by
the Underwriters.

   As a condition  to the  Underwriters'  obligation  to purchase  the shares of
Common Stock offered hereby,  the Underwriters must have received the opinion of
Bass & Ullman, P.C. on issues relating to FDA, FTC and state and local licensing
matters.  The  opinion  must state  that,  unless  otherwise  disclosed  in this
Prospectus,  the Company's  advertising  and packaging  complies with applicable
laws, the Company has all required  licenses and permits and the descriptions in
this Prospectus regarding government regulations and the status of the Company's
compliance with such regulations are not misleading.
    

   The Company has granted an option to the  Underwriters  to  purchase,  in the
aggregate,  up to  195,000  additional  shares of Common  Stock.  The  option is
exercisable for 45 days from the date of this Prospectus at an initial  offering
price,  less underwriting  discounts and commissions,  as set forth on the cover
page of this  Prospectus.  The option may only be  exercised  for the purpose of
covering  over-allotments  incurred  in the sale of the  shares of Common  Stock
offered hereby.

   
   The  Underwriters  will  purchase  the Common Stock  (including  Common Stock
subject to the Over- allotment  Option) from the Company at a price of $6.37 per
share. In addition,  the Company has agreed to pay to the  Representatives  a 3%
nonaccountable  expense allowance on the aggregate initial public offering price
of the shares of Common Stock,  including  shares subject to the  Over-allotment
Option,  of which $25,000 has been paid. The Company has agreed to indemnify the
Underwriters  against  certain  liabilities,  including  liabilities  under  the
Securities  Act,  or to  contribute  to  payments  that any  Underwriter  may be
required to make in respect thereof.
    

   The  Company  has  agreed  to issue  to the  Representatives,  for  aggregate
consideration of $100, the Representatives' Warrant to purchase up to 10% of the
number of shares of Common Stock sold in this
                                       48
<PAGE>
   
Offering for $8.54 per share.  The number of shares of Common  Stock  covered by
the  Representatives'  Warrants and the exercise price are subject to adjustment
under certain  events to prevent  dilution.  The  Representatives'  Warrants are
exercisable  at any time in the five-year  period  commencing  one year from the
effective  date  of  this  Offering.  The  Representatives'   Warrants  are  not
transferable  for one year  from the date of this  Prospectus  except  (i) to an
Underwriter  or a  partner  or  officer  of an  Underwriter  or  (ii) by will or
operation of law. During the term of the Representatives'  Warrants,  the holder
thereof is given the  opportunity  to profit from a rise in the market  price of
the  Company's  securities.  The  Company  may find it more  difficult  to raise
additional equity capital while the  Representatives'  Warrants are outstanding.
At any time at which the  Representatives'  Warrants are likely to be exercised,
the Company would probably be able to obtain  additional  equity capital on more
favorable terms. Additionally,  the Company has agreed, beginning one year after
the date of this  Prospectus,  on demand of the  holders  of a  majority  of the
Representatives'  Warrants or the Common Stock issued or issuable thereunder, to
register the Common Stock underlying the  Representatives'  Warrants one time at
the Company's expense. If the Company files a registration statement relating to
an equity  offering  under the provisions of the 1933 Act at any time during the
period  following  the date of issuance of the  Representatives'  Warrants,  the
holders of the  Representatives'  Warrants or underlying  Common Stock will have
the  right,  subject  to certain  conditions,  to  include in such  registration
statements, at the Company's expense, all or part of the underlying Common Stock
at the request of the holders.  The  registration of securities  pursuant to the

Common  Stock.  The  initial  public  offering  price for the  Common  Stock was
determined by negotiation among the Company and the  Representatives.  Among the
factors  considered in  determining  the initial  public  offering price was the
history  of and the  prospects  for the  Company  and the  industry  in which it
operates,  the past and present  operating results of the Company and the trends
of such  results,  the future  prospects of the Company,  an  assessment  of the
Company's  management,  the general  condition of the securities  markets at the
time of this  Offering  and the  prices for  similar  securities  of  comparable

                        REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors and Shareholders
M.D. Labs, Inc.

   We have audited the  accompanying  consolidated  balance sheet of M.D.  Labs,
Inc. and subsidiary as of May 31, 1996, and the related consolidated  statements
of income,  shareholders'  equity,  and cash flows for the two years then ended.
These consolidated  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 audits 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  consolidated  financial  statements  referred to above
present fairly, in all material respects, the consolidated financial position of
M.D. Labs, Inc. and subsidiary as of May 31, 1996, and the consolidated  results
of their  operations  and  their  cash  flows for the two  years  then  ended in
conformity with generally accepted accounting principles.

                  Notes to Consolidated Financial Statements

1. ORGANIZATION AND OPERATIONS:

   M.D. Labs, Inc. and its subsidiary, Belnik Investment Group, Inc., are in the
business of developing,  packaging,  marketing and distributing  natural dietary
supplements  (consisting  primarily of herbal  products)  and weight  management
products.  The formulation,  processing,  packaging,  labeling,  product claims,
advertising and marketing,  including  direct  marketing,  of these products are
subject to regulation in the U.S. by one or more federal agencies, including the
FDA, the FTC, the  Consumer  Product  Safety  Commission,  the USDA,  the United
States Postal Service and the Environmental Protection Agency. Sales are made to
large retailers,  distributors and consumers, primarily in the United States and
Japan.

   
   M.D. Labs, Inc., a Delaware  corporation,  was incorporated in February 1996.
On May 31, 1996, it exchanged  three million  shares of its common stock for all
of the investment units of Houston Enterprises,  L.L.C. (the "Predecessor"),  an
Arizona limited liability company.  Concurrently, but prior to the exchange, the
members of the Predecessor sold in a private  placement  approximately  16.6% of
their investment units for $1,744,313. The Company received no proceeds from the
sale; however, private placement costs of approximately $70,000 were paid by the
Company.     

   On February 26, 1996, M.D. Labs, Inc.  acquired from common owners all of the
assets  of Belnik  Investment  Group,  Inc.  ("Belnik")  from two  owners of the
Predecessor  for $1,000 and  warrants to purchase  21,000  shares of M.D.  Labs'
common stock.

   On January 16, 1996,  the  Predecessor  purchased  all the assets of Olympian
Global, L.L.C., an unaffiliated Arizona limited liability company, for $260,000.
The excess of cost over the fair value of the net assets acquired of $240,000 is
included in intangibles.  On February 14, 1994, the Predecessor purchased all of
the assets of Houston  Enterprises,  Inc., an unaffiliated  Arizona corporation,
for  $1,350,000.  The  excess  of cost  over  the fair  value of the net  assets
acquired  of  $506,328  is  included  in  intangibles.  Both  transactions  were
accounted  for in  accordance  with  the  purchase  method  of  accounting  and,
accordingly,  the results of operations  have been included in the  consolidated
results of operations from the respective dates of acquisition.

2. SIGNIFICANT ACCOUNTING POLICIES:

Basis of Presentation

   M.D. Labs, Inc., its Predecessor, and Belnik have historically operated under
a high degree of common  ownership  and  management  control.  Accordingly,  the
consolidated  financial  statements include the accounts of M.D. Labs, Inc., its
wholly-owned  subsidiary,  Belnik and its  Predecessor  (the  "Company") for all
periods  presented.   All  intercompany  balances  and  transactions  have  been
eliminated.

   The accompanying  consolidated  financial  statements at May 31, 1996 reflect
the exchange of common shares for the investment  units of its  Predecessor,  an
L.L.C.

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.

Cash and Cash Equivalents

   For  purposes of the  statements  of cash flows,  the Company  considers  all
highly liquid investments with a maturity of three months or less at the time of
acquisition to be cash  equivalents,  carried at cost, which  approximates  fair
value. At times,  the Company's cash deposited in financial  institutions may be
in excess of federally insured limits.

            Notes to Consolidated Financial Statements - (Continued)

Inventories

   Inventories are stated at the lower of cost or market.  Cost is determined on
a first-in,  first-out basis.  Inventories  consist primarily of finished goods,
finished but not packaged (semi-finished) goods, raw herbs and packaging.

Property and Equipment

   Property  and  equipment  are stated at cost.  Depreciation  is  provided  on
depreciable assets by the straight-line method over estimated useful lives while
leasehold  improvements  are  amortized  by the  straight-line  method  over the
shorter of estimated useful lives or the remaining lease terms.

   When items are retired or disposed of, the cost and accumulated  depreciation
or  amortization  are removed from the accounts and any gain or loss is included
in the statements of income. 

Intangible Assets

   Amortization of the intangibles is as follows:

          Goodwill, including trademarks                        15 years
          Non-compete agreements                                 3 years
          Product propriety rights                              10 years

   The Company  assesses the  recoverability  of goodwill at each balance  sheet
date by  determining  whether  amortization  of the assets  over their  original
estimated useful life can be recovered  through  estimated  future  undiscounted
operating income, excluding amortization. 

Revenue Recognition

   Sales and related  cost of sales are  recorded at the time of shipment  and a
provision  for  anticipated  sales  returns is  recorded  based upon  historical
experience.

Stock-Based Compensation

   In October 1995, the Financial  Accounting  Standards Board issued  Financial
Accounting  Standard No. 123,  Accounting  for  Stock-Based  Compensation  ("FAS
123"),  which defines a fair value based method of accounting for employee stock
options or similar  equity  instruments.  However,  it also  allows an entity to
continue to account for these plans  according to  Accounting  Principles  Board
Opinion  No. 25 ("APB  25"),  provided  proforma  disclosures  of net income and
earnings  per share are made as if the fair  value  based  method of  accounting
defined  by FAS 123 had  been  applied.  The  Company  anticipates  electing  to
continue to measure  compensation  expense  related to employee  stock  purchase
options using APB 25, and will provide proforma disclosures as required.

Income Taxes

   For the two years ended May 31, 1996, the Predecessor  elected under Internal
Revenue Code  Sub-Chapter K to be treated as a limited  liability  company,  and
accordingly,  is generally  not subject to federal and state income  taxes.  For
income tax  reporting  purposes  for these  years,  all profits and losses,  and
certain  other  items,  were passed  through to the members of the  Predecessor.
Since the  income of M.D.  Labs,  Inc.  will be  taxable  after May 31,  certain
temporary  differences  between  financial and tax reporting are reflected as an
income tax  benefit in the  statement  of income for the year ended May 31, 1996
and as deferred tax assets in the balance sheet as of May 31, 1996.

7. NOTES PAYABLE:

   At May 31, 1996, notes payable included:

Promissory note payable to Belfer Labs, L.L.C., a related party, due
  March 6, 1997, 12% interest ........................................ $ 300,000
Note payable to Olympian Global, L.L.C., 7.5% interest, collateralized
  by the right to the tradename of the purchased product line ........   160,000
                                                                       ---------
                                                                       $ 460,000
                                                                       =========

   The Belfer  note is  collateralized  by  substantially  all of the  Company's
assets.

   The  Olympian  note  matures on the  earliest of February 28, 1997 or 30 days
after the Company becomes a publicly traded company. The note also provides that
if certain sales levels are reached prior to January 13, 1997,  the Company must
pay an additional  $40,000.  Based on current sales levels, the Company does not
believe  that  payment of this amount is  probable;  therefore,  no liability is
reflected in the financial statements.

   
   Additionally, Olympian Global guaranteed that sales levels for the six months
ended  July 31,  1996  would be  $240,000  and that the amount of any such sales
shortfall  would be reduced  from the  principal  balance of the note.  Based on
sales through July 31, 1996, the Company is entitled to a reduction in principal
of approximately  $16,000. If any reduction in principal results from the above,
there will be no affect on net income since the  reduction in principal  will be
credited to goodwill. 
    

8. COMMITMENTS:

   M.D. Labs, Inc. is obligated under a long-term operating lease for office

            Notes to Consolidated Financial Statements - (Continued)
   
   On June 1, 1996,  options were granted to purchase  224,000  shares of common
stock at $3.50 a share and  additional  options were  granted to purchase  5,000
shares of common stock at $6.00 a share. These options will vest as to one third
of the  underlying  shares on each of the June 1,  1997,  1998 and  1999.  Also,
options were granted to certain  directors to purchase  40,000  shares of common
stock at $8.00 a share. The directors'  options were 100% vested as of September
1996.

4. THREATENED LITIGATION:

   In  September  1996,  the Company  received  correspondence  from an overseas
trading  company  threatening  to  institute  litigation  in Japan.  The trading
company  alleges the Company  breached a contract  by failing to  designate  the
trading company as the exclusive  distributor of Citrium(TM)  gum in Japan.  The
trading company is claiming damages of $500,000. The Company has not been served
with a lawsuit in this matter as of October 23, 1996. The Company  believes that
it is  reasonably  possible  that the  allegations  could  result in the Company
paying certain  damages.  As of August 31, 1996, the Company has not accrued any
amounts in connection with this threatened litigation.

5. SUBSEQUENT EVENTS:

   The Company has filed a Form SB-2  Registration  Statement  for the  proposed
public  offering of 1,300,000  common  shares.  A portion of the net proceeds of
this offering will be used to develop new product lines and repay  existing note
agreements.

   The  Company's  royalty  agreement  for the  Citrium  gum was  terminated  in
September 1996.

                     INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 24. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

   Section  145(a)  of  the  Delaware  General  Corporation  Law  (the  "General
Corporation Law") provides that a Delaware  corporation may indemnify any person
who was or is a party or is  threatened  to be made a party  to any  threatened,
pending or  completed  action,  suit or  proceeding,  whether  civil,  criminal,
administrative or investigative  (other than an action by or in the right of the
corporation)  by  reason  of the  fact  that he is or was a  director,  officer,
employee or agent of the  corporation or is or was serving at the request of the
corporation as a director,  officer, employee or agent of another corporation or
enterprise,  against expenses,  judgments,  fines and amounts paid in settlement
actually and reasonably  incurred by him in connection with such action, suit or
proceeding if he acted in good faith and in a manner he  reasonably  believed to
be in or not opposed to the best interests of the corporation, and, with respect
to any criminal  action or  proceeding,  had no cause to believe his conduct was
unlawful.

   Section 145(b) provides that a Delaware  corporation may indemnify any person
who was or is a party or is  threatened  to be made a party  to any  threatened,
pending or  completed  action or suit by or in the right of the  corporation  to
procure a judgment in its favor by reason of the fact that such person  acted in
any of the capacities set forth above,  against expenses actually and reasonably
incurred by him in  connection  with the defense or settlement of such action or
suit if he acted under similar standards,  except that no indemnification may be
made in respect to any claim, issue or matter as to which such person shall have
been adjudged to be liable to the corporation unless and only to the extent that
the court in which such action or suit was brought shall  determine that despite
the adjudication of liability,  such person is fairly and reasonably entitled to
be indemnified for such expenses which the court shall deem proper.

   Section  145 further  provides  that to the extent a director or officer of a
corporation has been successful in the defense of any action, suit or proceeding
referred to in subsections (a) and (b) or in the defense or any claim,  issue or
matter therein, he shall be indemnified against expenses actually and reasonably
incurred by him in connection  therewith;  that indemnification  provided for by
Section  145  shall  not be deemed  exclusive  of any other  rights to which the
indemnified  party may be entitled;  and that the  corporation  may purchase and
maintain insurance on behalf of a director or officer of the corporation against
any  liability  asserted  against him or incurred by him in any such capacity or
arising out of his status as such, whether or not the corporation would have the
power to indemnify him against such liabilities under such Section 145.

   Section 102(b)(7) of the General  Corporation Law provides that a corporation
in its original  certificate of  incorporation  or an amendment  thereto validly
approved by stockholders may eliminate or limit personal liability of members of
its board of directors or governing body for violations of a director's  duty of
care.  However,  no such  provision  may  eliminate or limit the  liability of a
director  for  breaching  his duty of loyalty,  acting or failing to act in good
faith,  engaging in intentional  misconduct or knowingly violating a law, paying
an unlawful dividend or approving an unlawful stock repurchase,  or obtaining an
improper  personal  benefit.  A  provision  of this  type has no  effect  on the
availability of equitable remedies, such as injunction or rescission, for breach
of fiduciary duty. The Company's  Certificate of  Incorporation  contains such a
provision.

   The Company's  Bylaws provide that the Company shall  indemnify  officers and
directors to the full extent  permitted by and in the manner  permissible  under
the laws of the State of Delaware.

   
   The  Company  is in the  process of  obtaining  comprehensive  directors  and
officers liability  insurance coverage,  and anticipates  obtaining an insurance
policy  with an  aggregate  policy  limit of not less  than  $3,000,000  for the
benefit of its officers and  directors  insuring  such persons  against  certain
liabilities,  including liabilities under the securities laws, no later than the
effective date of this Offering. 
    

   The Company has entered into  indemnity  agreements  with its  directors  and
officers for  indemnification  of and advance of expenses to such persons to the
full extent  permitted  by law. The Company  intends to execute  such  indemnity
agreements with its future officers and directors.
                                      II-1
<PAGE>
   The Company and its officers,  directors and other persons are entitled to be
indemnified under certain circumstances for certain securities law violations in
the Underwriting Agreement (attached on Exhibit 1.1 hereto).

   The holders of the Company's  capital  stock or warrants to purchase  capital
stock who have contractual registration rights are required to be indemnified by
the Company against losses,  claims,  damages or liabilities  arising out of any
untrue  statement  of a material  fact or  omission  thereof  in a  Registration
Statement  under  the  Securities  Act of  1933.  The  Company's  obligation  to
indemnify  such holders  includes the  officers,  directors and partners of such
holders,  some of whom are currently directors of the Company. The Company shall
not be liable for any such  indemnity  to the extent that any such loss,  claim,
damage or  liability  arises  out of or is based upon any  untrue  statement  or
material  omission in reliance upon and in conformity  with written  information
furnished by such person to the Company, specifically for use therein.

   The  indemnification  provided  as set forth  above is not  exclusive  of any
rights to which a director  or  officer  of the  Company  may be  entitled.  The
general effect of the forgoing  provisions may be to reduce the circumstances in
which a director or officer may be required to bear the economic  burdens of the
foregoing liabilities and expenses.

ITEM 26. RECENT SALES OF UNREGISTERED SECURITIES.

   Set forth below is information regarding  unregistered sales of the Company's
Common Stock since January 1, 1996:

   
   On May 31,  the  Company  issued  3,000,000  shares  of its  Common  Stock in
exchange for 100% of the  outstanding  units of  membership  interest in Houston
Enterprises,  L.L.C., the Company's  predecessor in reliance on Section 4(2) and
Rule 506 of the  Securities  Act.  No cash was  involved  in the  exchange.  The
membership  units were held by the  officers  and  directors  of the Company and
those who purchased the units as described in the following sentence. Certain of
the units of interest  in Houston  Enterprises,  L.L.C.  were sold by members of
Houston Enterprises,  L.L.C. to persons who represented themselves as accredited
investors for $105,000 per unit in the weeks prior to each unit being  exchanged
for 30,000  shares of the Company's  Common Stock.  The members paid a placement
fee of $5,250 per unit placed and the Company issued warrants to purchase 10,765
shares of Common  Stock to Capital West Holding  Company,  Inc.,  which acted as
private  placement  agent  for the  selling  members.  In  connection  with  the
transactions,  the Company  also issued  warrants  to purchase an  aggregate  of
107,656 shares of Common Stock to entities  associated with an attorney involved
in the placement and to a director of the Company who subsequently resigned.
    

   On February 7, the Company issued warrants to purchase an aggregate of 21,000
shares of Common Stock,  at an exercise price of $1.00 per share, to officers of
the Company in connection with the purchase
                                      II-2
<PAGE>
of Belnik Investment Group, Inc. from the officers. See "Certain  Transactions."
On that same date,  the Company  issued  warrants to purchase  30,000 and 60,000
shares of Common Stock at exercise prices of $1.00 and $0.50 respectively, to an
officer of the Company in connection with his employment agreement.

   
   On June 3, 1996,  the Company  issued a warrant to purchase  75,000 shares of
Common  Stock at an  exercise  price of $5.00 per share and  another  warrant to
purchase  75,000  shares at an exercise  price of $10.00 per share to Michael J.
Dwyer, a stock broker familiar with the Company,  for $1,500. On that same date,
the Company  issued a warrant to purchase  40,000  shares of Common  Stock at an
exercise  price of $3.50 per share to a director  of the  Company in  connection
with his  consulting  agreement  (see  "Management"),  and a warrant to purchase
45,000  shares of Common  Stock at an  excersize  price of $3.50 per share to an
employee of the Company.

   In September  1996, the Company granted  warrants to purchase  100,000 shares
and 14,000  shares to a Company  director/consultant  and a paid endorser of the
Company's  products,  respectively in connection  with their service  agreements
with the Company.  The warrants to purchase  100,000  shares are  exercisable at
$7.00 per share and vest pro-rata each day during the year  beginning  August 1,
1996. The warrants to purchase 14,000 shares are exercisable at $6.00 per share,
and vest 7,000 shares on each  September 14, 1997 and  September  14, 1998.  The
warrants were not issued for cash.

   Since June 1996,  the Company has issued  options to purchase an aggregate of
269,000  shares of Common Stock to its employees  and directors  pursuant to the
Company's  Stock  Option Plan at option  exercise  prices  ranging from $3.50 to
$8.00 per  share.  There was no  charge  to the  optionees  for the grant of the
options.

   Exemption from registration for each transaction described above, if deemed a
sale of securities,  was claimed  pursuant to Section 4(2) of the Securities Act
of 1933.

ITEM 27. EXHIBITS.

   See Exhibit  Index  following  the Signature  page which is  incorporated  by
herein by reference.

ITEM 28. UNDERTAKINGS.
    

   The undersigned  Registrant hereby undertakes to provide to the Underwriters,
at the closing  specified in the  underwriting  agreement,  certificates in such
denominations  and registered in such names as required by the  Underwriters  to
permit prompt delivery to each purchaser.

   Insofar as indemnification  for liabilities  arising under the Securities Act
of 1933 may be permitted to directors,  officers and controlling  persons of the
Registrant pursuant to the foregoing  provisions,  or otherwise,  the Registrant
has been advised that in the opinion of the Securities  and Exchange  Commission
such  indemnification  is against  public policy as expressed in the Act and is,
therefore,  unenforceable. In the event that a claim for indemnification against
such liabilities  (other than the payment by the Registrant of expenses incurred
or paid by a director,  officer or  controlling  person of the Registrant in the
successful  defense of any  action,  suit or  proceeding)  is  asserted  by such
director,  officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been  settled by  controlling  precedent,  submit to a court of  appropriate
jurisdiction the question whether such  indemnification  by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.

   The undersigned Registrant hereby undertakes that:

   (1) For purposes of  determining  any liability  under the  Securities Act of
1933,  the  information  omitted from the form of prospectus  filed as part of a
registration  statement in reliance  upon Rule 430A and contained in the form of
prospectus  filed by the Registrant  pursuant to Rule 424(b)(1) or (4) or 497(h)
under the Securities Act of 1933 shall be deemed to be part of the  registration
statement as of the time the Commission declared it effective.

   (2) For  determining  any liability  under the Securities  Act of 1933,  each
post-effective  amendment that contains a form of prospectus  shall be deemed to
be a new  registration  statement  relating  to the  securities  offered  in the
registration statement,  and that offering of the securities at that time as the
initial bona fide offering of those securities.

   In  accordance  with the  requirements  of the  Securities  Act of 1933,  the
registrant  hereby  certifies that it has reasonable  grounds to believe that it
meets all of the  requirements  of filing on Form SB-2, and has authorized  this
amended registration  statement to be signed on its behalf by the undersigned in
the City of Phoenix, State of Arizona, on October 25, 1996.

(As Representatives of the Several
Underwriters Named in Schedule 1 hereto)

Dear Sirs:

         M.D.  Labs,  Inc.,  a  Delaware  corporation  (the  "Company"),  hereby
confirms its agreement (this "Agreement") with the several underwriters named in
Schedule 1 hereto (the "Underwriters"),  for whom Sentra Securities  Corporation
and Spelman & Co., Inc. have been duly authorized to act as representatives  (in
such capacity, the "Representatives"), as set forth below:
    

                                   SECTION 1.
                           Description of Transaction
   
         The  Company  proposes  to issue  and sell to the  Underwriters  on the
Closing Date (as defined  below),  pursuant to the terms and  conditions of this
Agreement,  an aggregate of 1,300,000  shares  ("Firm  Shares") of the Company's
Common  Stock  ("Common  Stock")  at a price of $____  per Share on the terms as
hereinafter  set  forth.  The  Company  also  proposes  to issue and sell to the
several  Underwriters  on or  after  the  Closing  Date not  more  than  195,000
additional  Shares if  requested by the  Representatives  as provided in Section

                                        2
<PAGE>
                                   SECTION 2.
                  Representations and Warranties of the Company

         In order to induce the  Underwriters to enter into this Agreement,  the
Company hereby represents and warrants to and agrees with the Underwriters that:

   
                  2.1  Registration  Statement and  Prospectus.  A  registration
statement  on Form SB- 2 (File No.  333-_______)  with  respect  to the  Shares,
including the related prospectus, copies of which have heretofore been delivered
by the Company to the Underwriters,  has been filed by the Company in conformity
with  the   requirements   of  the  Securities  and  Exchange   Commission  (the
"Commission")  under the Securities Act of 1933, as amended (the "Act"), and one
or more amendments to such registration  statement have been so filed. After the
execution of this  Agreement,  the Company will file with the Commission  either
(a) if such  registration  statement,  as it may  have  been  amended,  has been
declared by the  Commission  to be effective  under the Act, a prospectus in the
form most recently included in an amendment to such registration  statement (or,
if no such amendment  shall have been filed,  in such  registration  statement),
with such  changes or  insertions  as are required by Rule 430A under the Act or
permitted by Rule 424(b) under the Act and as have been provided to and approved
by the Representatives prior to the execution of this Agreement,  or (b) if such
registration  statement,  as it may have been amended,  has not been declared by
the Commission to be effective under the Act, an amendment to such  registration
statement,  including a form of prospectus,  a copy of which  amendment has been
furnished to and approved by the Representatives  prior to the execution of this
Agreement.  As used in this Agreement,  the term "Registration  Statement" means
such registration statement on Form SB- 2 and all amendments thereto,  including
the prospectus,  all exhibits and financial statements, as it becomes effective;
the  term  "Preliminary  Prospectus"  means  each  prospectus  included  in said
Registration  Statement before it becomes  effective;  and the term "Prospectus"
means the  prospectus  first filed with the  Commission  pursuant to Rule 424(b)
under the Act or, if no prospectus is required to be filed pursuant to said Rule
424(b),  such term means the prospectus  included in the Registration  Statement
when it becomes effective.
    

                  2.2 Accuracy of Registration Statement and Prospectus. Neither
the  Commission nor the "blue sky" or securities  authority of any  jurisdiction
has  issued  any  order  preventing  or  suspending  the use of any  Preliminary
Prospectus.  When (a) any Preliminary  Prospectus was filed with the Commission,
(b) the  Registration  Statement  or any  amendment  thereto  was or is declared
effective,  and (c) the  Prospectus or any  amendment or  supplement  thereto is
filed with the Commission pursuant to Rule 424(b) (or, if the Prospectus or such
amendment or  supplement is not required to be so filed,  when the  Registration
Statement or the amendment  thereto  containing  such amendment or supplement to
the  Prospectus  was or is  declared  effective)  and on the  Closing  Date  the
Prospectus,  as  amended  or  supplemented  at any such  time,  such  filing (i)
contained  or will  contain  all  statements  required  to be stated  therein in
accordance  with, and complied or will comply in all material  respects with the
requirements  of,  the Act and  the  rules  and  regulations  of the  Commission
promulgated  thereunder (the "Rules and  Regulations")  and (ii) did not or will
not  include  any  untrue  statement  of a  material  fact or omit to state  any
material fact necessary to make
                                        3
<PAGE>
   
the statements therein not misleading in light of the circumstances  under which
they were made.  The  foregoing  representation  does not apply to statements or
omissions made in any Preliminary Prospectus,  the Registration Statement or any
amendment  thereto or the  Prospectus or any amendment or supplement  thereto in
reliance  upon and in  conformity  with  written  information  furnished  to the
Company by any  Underwriter  through the  Representatives  specifically  for use
therein.
    

                  2.3  Incorporation  and  Standing.  The  Company has been duly
incorporated and is validly existing as a corporation in good standing under the
laws of the State of Delaware and is duly  qualified  to transact  business as a
foreign  corporation  and is in  good  standing  under  the  laws  of all  other
jurisdictions where the ownership or leasing of its properties or the conduct of
its  business  requires  such  qualification,  except where the failure to be so
qualified does not amount to a material liability or disability to the Company.
   
                  2.4 Due Power and  Authority.  The Company has full  corporate
power to own or lease its  properties  and conduct its  business as described in
the  Registration  Statement and the  Prospectus or, if the Prospectus is not in
existence,  the most  recent  Preliminary  Prospectus;  and the Company has full
corporate  power to enter into this Agreement and to carry out all the terms and
provisions  hereof to be carried out by it. The  execution  and delivery of this
Agreement and  consummation of the  transactions  contemplated  herein have been
duly  authorized  by the Company and this  Agreement  has been duly executed and
delivered by the Company and constitutes the legal, valid and binding obligation
of the Company,  enforceable  against the Company in  accordance  with the terms
thereof,  except  as  may  be  limited  by  applicable  bankruptcy,  insolvency,
reorganization  or similar laws  affecting  creditors'  rights  generally and by
general  equitable  principles,  and as rights  to  indemnity  and  contribution
hereunder may be limited by applicable law.
    
                  2.5 Consents; No Defaults. The issuance,  offering and sale of
the Shares to the  Underwriters by the Company  pursuant to this Agreement,  the
compliance by the Company with the other  provisions  of this  Agreement and the
consummation of the other  transactions  herein  contemplated do not (a) require
the consent, approval,  authorization,  registration or qualification of or with
any  governmental  authority,  except such as have been  obtained,  or as may be
required  under  the  Act or  under  the  securities  or  blue  sky  laws of any
jurisdiction,  or (b) conflict with or result in a breach or violation of any of
the terms and  provisions  of, or  constitute a default  under,  any  indenture,
mortgage,  deed of trust,  lease or other  material  agreement or  instrument to
which the Company is a party or by which the Company or any of its properties is
bound, or the charter documents or bylaws of the Company,  or any statute or any
judgment,  decree,  order, rule or regulation of any court or other governmental
authority or any arbitrator applicable to the Company.
   
                  2.6 No Breach or Default.  The Company is not in breach of any
term or provision of its  Certificate  of  Incorporation  or Bylaws;  no default
exists,  and no event has  occurred  which with notice or lapse of time or both,
would  constitute a default,  in the Company's due performance and observance of
any term,  covenant or  condition  of any  indenture,  mortgage,  deed of trust,
lease,  note, bank loan or credit  agreement or any other material  agreement or
instrument to
    
                                        4
<PAGE>
which the  Company or its  properties  may be bound or  affected  in any respect
which  would have a  material  adverse  effect on the  condition  (financial  or
otherwise), business, properties,  prospects, net worth or results of operations
of the Company.
   
                  2.7  Licenses.  Except as  described  in the  Prospectus,  the
Company  possesses all  certificates,  authorizations  and permits issued by the
appropriate federal,  state or foreign regulatory  authorities necessary for the
conduct  of its  business,  including  without  limitation  the  Food  and  Drug
Administration,  the Federal  Trade  Commission,  the  Consumer  Product  Safety
Commission,  the United  States  Department  of  Agriculture,  the United States
Postal Service and the Environmental  Protection Agency, and the Company has not
received any notice of proceedings relating to the revocation or modification of
any such certificate, authorization or permit which, singly or in the aggregate,
if the subject of an unfavorable decision,  ruling or finding, would result in a
material  adverse  change in the condition  (financial or  otherwise),  business
prospects,  net  worth or  results  of  operations  of the  Company,  except  as
described in or  contemplated  by the  Registration  Statement.  Each  approval,
registration,  qualification,  license,  permit, consent, order,  authorization,
designation, declaration or filing by or with any regulatory,  administrative or
other governmental body or agency necessary in connection with the execution and
delivery  by  the  Company  of  this  Agreement  and  the  consummation  of  the
transactions  contemplated (except such additional actions as may be required by
the National  Association  of  Securities  Dealers,  Inc. or may be necessary to
qualify the Common Stock for public offering under state  securities or blue sky
laws) has been obtained or made and each is in full force and effect.
    
                  2.8  Compliance   with  Laws.   Except  as  disclosed  in  the
Registration  Statement and in the  Prospectus  (or, if the Prospectus is not in
existence,  the most  recent  Preliminary  Prospectus),  the  Company  is not in
violation of any laws, ordinances, governmental rules or regulations to which it
is subject,  including  but not limited to the Federal  Food,  Drug and Cosmetic
Act,  the  Nutrition  Labeling  and  Education  Act of  1990,  and  the  Dietary
Supplement Health and Education Act of 1994, which would have a material adverse
effect  on  the  condition  (financial  or  otherwise),   business,  properties,
prospects, net worth or results of operations of the Company.

                  2.9 Existing  Capital  Structure and Shareholder  Rights.  The
Company has an authorized,  issued and outstanding  capitalization  as set forth
in, and capital  stock  conforms  in all  material  respects to the  description
contained in, the Prospectus or, if the Prospectus is not in existence, the most
recent Preliminary Prospectus. Except as described in the Registration Statement
and in the Prospectus  there are no outstanding (a) securities or obligations of
the  Company  convertible  into or  exchangeable  for any  capital  stock of the
Company,  (b) warrants,  rights or options to subscribe for or purchase from the
Company  any  such  capital  stock  or  any  such  convertible  or  exchangeable
securities  or  obligations,  or (c)  obligations  of the  Company to issue such
shares, any such convertible or exchangeable  securities or obligations,  or any
such warrants, rights or obligations.  All of the issued shares of capital stock
of the Company have been duly  authorized  and validly issued and are fully paid
and nonassessable, and have been issued in compliance with all federal and state
securities laws. No preemptive rights of shareholders  exist with respect to any
capital  stock of the  Company.  No  shareholder  of the  Company  has any right
pursuant to any
                                        5
<PAGE>
   
agreement  which has not been  waived or  honored  to  require  the  Company  to
register the sale of any securities owned by such  shareholder  under the Act in
the public offering  contemplated herein except as disclosed in the Registration
Statement.  Other than MDLA, Inc. and Belnik Investment Group, Inc., the Company
has no  subsidiaries,  and does not own any shares of stock or any other  equity
interest in any firm, partnership, association or other entity.
    
                  2.10  Authority  for  Issuance of Shares.  The issuance of the
Common Stock issuable in connection with the Shares has been duly authorized and
at any Firm or Option Closing Date as defined  herein after payment  therefor in
accordance  herewith,  such Common Stock will be validly issued,  fully paid and
nonassessable.  The  Shares  will  conform  in all  material  respects  with all
statements with regard thereto in the Registration Statement and the Prospectus.
   
                  2.11 Title to Tangible Property. Except as otherwise set forth
in or contemplated by the Registration Statement and Prospectus, the Company has

                  3.1   Purchase   of  Firm   Shares.   On  the   basis  of  the
representations,  warranties,  agreements  and  covenants  herein  contained and
subject to the terms and  conditions  herein set forth,  the  Company  agrees to
issue and sell to each of the Underwriters  named in Schedule I hereto, and each
of the  Underwriters,  severally  and not jointly,  agrees to purchase  from the
Company,  at a purchase price of $____ per Share,  the number of Firm Shares set
forth opposite the name of such  Underwriter  in Schedule 1 hereto.  The Company
will  make one or more  certificates  for  Common  Stock  constituting  the Firm
Shares,  in  definitive  form  and in such  denomination  or  denominations  and
registered  in such  name or names as the  Representatives  shall  request  upon
notice  to the  Company  at  least 48 hours  prior  to the  Firm  Closing  Date,
available for checking and
    
                                        9
<PAGE>
   
packaging by the  Representatives at the offices of the Company's transfer agent
or registrar (or the correspondent or the agent of the Company's  transfer agent
or registrar) at least 24 hours prior to the Firm Closing Date.  Payment for the
Firm Shares shall be made by bank wire payable in same day funds to the order of
the  Company  drawn to the order of the  Company  for the Firm  Shares,  against
delivery  of  certificates  therefor  to the  Representatives.  Delivery  of the
documents,  certificates and opinions  described in Section 6 of this Agreement,
the Firm Shares and payment for the Firm Shares and the Option  Shares  shall be
made at the offices of Sentra  Securities  Corporation,  2355  Northside  Drive,
Suite 200, San Diego,  California  92108,  at 9:00 a.m.,  San Diego time, on the
third full  business day  following the date hereof (on the fourth full business
day if this  Agreement is executed after 1:30 p.m.,  Arizona  time),  or at such
other places, time or date as the Representatives and the Company may agree upon
or as the  Representatives may determine pursuant to Section 9 hereof, such time
and date of  delivery  against  payment  being  herein  referred to as the "Firm
Closing Date."

                  3.2  Over-Allotments;   Option  Shares.  For  the  purpose  of
covering any over-allotments in connection with the distribution and sale of the
Firm Shares as contemplated by the Prospectus,  the Company hereby grants to you
on behalf of the several  Underwriters an option to purchase,  severally and not
jointly,  the Option Shares. The purchase price to be paid for any Option Shares
shall be the same price per share as the price per Share for the Firm Shares set
forth above in Section 3.1,  plus,  if the purchase and sale of any Option Share
takes place after the Firm  Closing  Date and after the Common  Stock is trading
"ex-dividend,"  an amount  equal to the  dividends  payable on the Common  Stock
contained in such Option  Shares.  The option granted hereby may be exercised in
the manner  described below as to all or any part of the Option Shares from time
to  time  within  forty-five  days  after  the  date  of  the  Prospectus.   The
Underwriters  shall not be under any  obligation  to purchase  any of the Option
Shares prior to the exercise of such option. The  Representatives  may from time
to time  exercise the option  granted  hereby by giving  notice in writing or by
telephone  (confirmed  in writing) to the Company  setting  forth the  aggregate
number of Option Shares as to which the several Underwriters are then exercising
the option and the date and time for  delivery  of and  payment  for such Option
Shares. Any such date of delivery shall be determined by the Representatives but
shall not be earlier than two business  days or later than seven  business  days
after such  exercise of the option and, in any event,  shall not be earlier than
the Firm Closing Date. The time and date set forth in such notice, or such other
time on such other date as the Representatives and the Company may agree upon or
as the  Representatives  may determine  pursuant to Section 9 hereof,  is herein
called the "Option  Closing Date" with respect to such Option Shares.  Upon each
exercise of the option as provided  herein,  subject to the terms and conditions
herein set forth,  the Company  shall  become  obligated  to sell to each of the
several Underwriters,  and each of the Underwriters  (severally and not jointly)
shall become obligated to purchase from the Company,  the same percentage of the
total number of the Option Shares as to which the several  Underwriters are then
exercising  the option as such  Underwriter  is  obligated  to  purchase  of the
aggregate  number of Firm  Shares,  as adjusted by the  Representatives  in such
manner  as it deems  advisable  to avoid  fractional  shares.  If the  option is
exercised as to all or any
    
                                       10
<PAGE>
   
portion of the Option  Shares,  one or more  certificates  for the Common  Stock
contained in such Option  Shares,  in definitive  form,  and payment  therefore,
shall be delivered on the related  Option  Closing Date in the manner,  and upon
the terms and  conditions,  set forth in  Section  3.1,  except  that  reference
therein to the Firm  Shares  and the Firm  Closing  Date  shall be  deemed,  for
purposes of this Section 3.2, to refer to such Option Shares and Option  Closing
Date,  respectively.  No Option  Shares shall be required to be, or be, sold and
delivered  unless the Firm Shares have been,  or  simultaneously  are,  sold and
delivered as provided in this Agreement.

                  3.3  Default by an  Underwriter.  It is  understood  that you,
individually and not as the Representatives, may (but shall not be obligated to)
make payment on behalf of any Underwriter or Underwriters  for any of the Shares
to be purchased  by such  Underwriter  or  Underwriters.  No such payment  shall
relieve such  Underwriter or Underwriters  from any of its or their  obligations
hereunder.
    
                                   SECTION 4.
                          Offering by the Underwriters
   
         Upon payment by the  Underwriters  of the  purchase  price of $____ per
Share and the  Company's  authorization  of the release of the Firm Shares,  the
several Underwriters shall offer the Firm Shares for sale to the public upon the
terms set forth in the  Prospectus.  The  Representatives  may from time to time
thereafter  change the public  offering  prices and other selling terms.  If the
option set forth in Section 3.2 of this  Agreement is  exercised,  then upon the
Company's  authorization  of  the  release  of the  Option  Shares  the  several
Underwriters  shall offer such Shares for sale to the public upon the  foregoing
terms.
    
                                   SECTION 5.
                            Covenants of the Company

         Except as otherwise stated below, the Company covenants and agrees with
each of the Underwriters that:

                  5.1 Company's Best Efforts to Cause Registration  Statement to
Become  Effective.   The  Company  will  use  its  best  efforts  to  cause  the
Registration  Statement,  if not  effective  at the  time of  execution  of this
Agreement,  and any  amendments  thereto,  to become  effective  as  promptly as
possible. If required, the Company will file the Prospectus and any amendment or
supplement  thereto with the Commission in the manner and within the time period
required  by Rule  424(b)  under  the Act.  During  any time  when a  prospectus
relating  to the Common  Stock is required to be  delivered  under the Act,  the
Company (a) will comply with all requirements imposed upon it by the Act and the
Rules and Regulations to the extent necessary to permit the continuance of sales
of or dealings in the Common Stock in accordance with the provisions  hereof and
of the Prospectus,  as then amended or supplemented,  and (b) will not file with
the Commission the prospectus or the
                                       11
<PAGE>
   
amendment  referred  to in the  second  sentence  of  Section  2.1  hereof,  any
amendment or supplement to such prospectus or any amendment to the  Registration
Statement  unless  and  until the  Representatives  have  been  advised  of such
proposed filing,  has been furnished with a copy for a reasonable period of time
prior to the proposed  filing,  and has given its consent to such filing,  which
shall not be unreasonably withheld or delayed.

                  5.2 Preparation and Filing of Amendments and Supplements.  The
Company will prepare and file with the Commission,  in accordance with the Rules
and  Regulations  of  the  Commission,  promptly  upon  written  request  by the
Representatives  or  counsel  for the  Representatives,  any  amendments  to the
Registration  Statement or amendments or supplements to the Prospectus  that may
be reasonably  necessary or advisable in connection with the distribution of the
Shares by the several Underwriters, and the Company will use its best efforts to
cause any such amendment to the Registration  Statement to be declared effective
by the  Commission  as  promptly  as  possible.  The  Company  will  advise  the
Representatives,  promptly after receiving notice thereof,  of the time when the
Registration  Statement  or any  amendment  thereto  has been filed or  declared
effective or the  Prospectus  or any  amendment or  supplement  thereto has been
filed and will provide evidence satisfactory to the Representatives of each such
filing or effectiveness.

                  5.3  Notice  of Stop  Orders.  The  Company  will  advise  the
Representatives  promptly after receiving notice or obtaining  knowledge of: (a)
the issuance by the Commission of any stop order suspending the effectiveness of
the Registration  Statement or any amendment thereto, or any order preventing or
suspending  the  use of any  Preliminary  Prospectus  of the  Prospectus  or any
amendment or supplement thereto;  (b) the suspension of the qualification of the
Shares  for  offering  or  sale  in  any  jurisdiction;   (c)  the  institution,
threatening or contemplation of any proceeding for any such purpose;  or (d) any
request made by the  Commission  for amending the  Registration  Statement,  for
amending or  supplementing  the  Prospectus or for additional  information.  The
Company will use its best efforts to prevent the issuance of any such stop order
and,  if any such  stop  order is issued to obtain  the  withdrawal  thereof  as
promptly as possible.

                  5.4 Blue Sky  Qualification.  The  Company  will  arrange  and
cooperate  with  counsel to the  Representatives  for the  qualification  of the
Shares  for  offering  and sale  under the  securities  or blue sky laws of such
jurisdictions  as the  Representatives  may  designate  and will  continue  such
qualifications  in  effect  for as  long as may be  necessary  to  complete  the
distribution of the Shares; provided,  however, that in connection therewith the
Company shall not be required to qualify as a foreign  corporation or to execute
a general consent to service of process in any jurisdiction.
    
                  5.5  Post-Effective   Amendments.  If,  at  any  time  when  a
prospectus relating to the Shares is required to be delivered under the Act, any
event  occurs  as  a  result  of  which  the  Prospectus,  as  then  amended  or
supplemented,  would include any untrue  statement of a material fact or omit to
state a material  fact  necessary  in order to make the  statements  therein not
misleading, in the light of
                                       12
<PAGE>
   
the  circumstances  under which they were made, or if for any other reason it is
necessary at any time to amend or supplement  the  Prospectus to comply with the
Act  or  the  Rules  or  Regulations,  the  Company  will  promptly  notify  the
Representatives  thereof and, subject to Section 3 hereof, will prepare and file
with the Commission,  at the Company's expense, an amendment to the Registration
Statement or an amendment or  supplement  to the  Prospectus  that corrects such
statement or omission or effects such compliance.

                  5.6  Delivery  of  Prospectuses.  The  Company  will,  without
charge,   provide   (a)  to  the   Representatives   and  to  counsel   for  the
Representatives  a signed copy of the  Registration  Statement  originally filed
with respect to the Shares and each  amendment  thereto (in each case  including
exhibits  thereto),  (b) to each other  Underwriter so requesting in writing,  a
conformed copy of such  Registration  Statement and each  amendment  thereto (in
each case without exhibits thereto) and (c) so long as a prospectus  relating to
the Shares is  required  to be  delivered  under the Act, as many copies of each
Preliminary  Prospectus or the Prospectus or any amendment or supplement thereto
as the Representatives may reasonably request.

                  5.7 Section  11(a)  Financials.  The Company  will, as soon as
practicable  but in any event not later than 90 days  after the  period  covered

subsidiaries  that satisfies the provisions of Section 11(a) of the Act and Rule
158 thereunder covering a twelve-month period beginning not later than the first
day of the Company's  fiscal  quarter next  following the effective  date of the
Registration Statement.
    
                  5.8  Application  of Proceeds.  The Company will apply the net
proceeds  from  the  sale of the  Shares  as set  forth  in the  Prospectus  and
Registration  Statement  and will not take any  action  that  would  cause it to
become an  investment  company  under the  Investment  Company  Act of 1940,  as
amended.
   
                  5.9 Sales of  Securities.  The Company  will not,  directly or
indirectly,  without the prior written  consent of the  Representatives,  offer,
sell, grant any option to purchase or otherwise  dispose (or announce any offer,
sale,  grant of any option to  purchase or other  disposition)  of any shares of
Common Stock or any securities  convertible into, or exchangeable or exercisable
for,  shares of Common  Stock  for a period of one year  after the date  hereof,
except (a) to the Underwriters pursuant to this Agreement and (b) options to any
person  pursuant to and in accordance with the Company's 1996 Stock Option Plan,
as such plan is in effect on the date hereof,  and provided that such person has
delivered to the  Representatives the agreement described in Section 7.8 of this
Agreement.
    
                  5.10 Application to Nasdaq National  Market.  The Company will
cause the Common Stock to be duly included for quotation on the Nasdaq  National

National  Market  following the Closing Date for a period of not less than three
years.

be  exercisable  for a per Share  exercise  price equal to 120% of the per Share
public offering price of the Firm Shares.

                  5.14 Cooperation With  Representatives' Due Diligence.  At all
times  prior  to  the  Closing  Date,   the  Company  will  cooperate  with  the
Representatives in such investigation as the  Representatives  may make or cause

connection  with the purchase and public  offering of the Shares and the Company
will  make  available  to  the  Representatives  in  connection  therewith  such
information in its possession as the Representatives may reasonably request.

with respect to the Company,  its financial  condition,  results of  operations,
business,  properties,  assets,  liabilities  and any of them, or this offering,

Representatives the market price of the Common Stock has been or is likely to be
materially  affected,  regardless  of whether such rumor,  publication  or event
necessitates a supplement to or amendment of the  Prospectus,  the Company will,
after  written  notice  from the  Representatives,  evaluate  the  propriety  of
disseminating a press release or other public statement reasonably acceptable to
the Representatives and their counsel,  commenting on such rumor, publication or
event.

                  5.17 Forecasts and Projections. For a period of two years from

or used by any of its subsidiaries or affiliated entities.
    
                                   SECTION 6.
                                    Expenses
   
                  6.1  Offering  Expenses.  The Company will pay upon demand all
costs and expenses  incident to the  performance  of the  Company's  obligations
under this Agreement,  whether or not the transactions  contemplated  herein are
consummated  or this  Agreement  is  terminated  pursuant  to Section 11 hereof,
including  all  costs  and  expenses  incident  to (a)  the  printing  or  other
production of documents with respect to the transactions, including any costs of
printing the Registration  Statement originally filed with respect to the Shares
and any amendment thereto, any Preliminary Prospectus and the Prospectus and any
amendment  or  supplement   thereto,   this   Agreement,   the  Agreement  Among
Underwriters, the Selected Dealer Agreement, and any blue sky memoranda, (b) all
arrangements  relating  to the  delivery  to the  Underwriters  of copies of the
foregoing documents, (c) the fees and disbursements of counsel,  accountants and
any other experts or advisors retained by the Company, (d) preparation, issuance
and  delivery to the  Underwriters  of any  certificates  evidencing  the Common
Stock, including transfer agent's and registrar's fees, (e) the qualification of
the Shares under state  securities and blue sky laws,  including filing fees and
fees and disbursements of counsel for the Representatives  relating thereto, (f)
the filing fees of the  Commission  and the National  Association  of Securities
Dealers,  Inc. relating to the Shares, (g) any listing fees for the quotation of
the Common Stock on the Nasdaq National Market, (h) one-half the cost of placing
"tombstone advertisements" in any publications which may be selected by
    
                                       15
<PAGE>
   
the  Representatives  (provided  that any such cost in  excess  of $5,000  shall
require the consent of both the  Company and the  Representatives),  and (i) all
other  advertising  that has been approved in advance by the Company relating to
the offering of the Shares (other than as shall have been specifically  approved
in  writing  by the  Representatives  to be paid  for by the  Underwriters).  In
addition to the foregoing,  the Company agrees to pay to the  Representatives  a
non-accountable  expense  allowance  of 3% of the gross amount to be raised from
the sale of the Shares  hereunder,  payable at the Closing(s),  of which $25,000
has already been paid by the Company in connection  with this  offering.  If the
sale of the Shares provided for herein is not consummated  because any condition
to the  obligations  of the  Underwriters  set forth in  Section  7 (other  than
Section  7.6) hereof is not  satisfied,  because this  Agreement  is  terminated
pursuant to Section 11 hereof or because of any failure, refusal or inability on
the part of the Company to perform all obligations and satisfy all conditions on
its part to be  performed  or  satisfied  hereunder  other  than by  reason of a
default by any of the Underwriters,  the Company will reimburse the Underwriters
severally upon demand for all out-of-pocket expenses (including counsel fees and
disbursements)  that shall have been  reasonably  incurred by them in connection
with the proposed purchase and sale of the Shares. The Company shall in no event
be liable to any of the  Underwriters  for the loss of anticipated  profits from
the transactions covered by this Agreement.
    
                  6.2 Interim  Indemnification.  The  Company  agrees that as an
interim measure during the pendency of any claim, action, investigation, inquiry
or other  proceeding  described  in Section 8.1 hereof,  it will  reimburse  the
Underwriters  on a monthly  basis  for all  reasonable  legal or other  expenses
incurred in connection with  investigating or defending any such claim,  action,
investigation,  inquiry or other  proceeding,  notwithstanding  the absence of a
judicial  determination as to the propriety and  enforceability of the Company's
obligation to reimburse the  Underwriters  for such expenses and the possibility
that  such  payments  might  later be held to have been  improper  by a court of
competent  jurisdiction.  To the  extent  that  any such  interim  reimbursement
payment is so held to have been improper, the Underwriters shall promptly return
such payment to the Company together with interest, compounded daily, determined
on the basis of the prime rate (or other  commercial  lending rate for borrowers
of the  highest  credit  standing)  listed  from time to time in THE WALL STREET
JOURNAL  which  represents  the  base  rate  on  corporate  loans  posted  by  a
substantial  majority  of the  nation's  thirty (30)  largest  banks (the "Prime
Rate").  Any  such  interim  reimbursement  payments  which  are not made to the
Underwriters  within thirty (30) days of a request for reimbursement  shall bear
interest at the Prime Rate from the date of such request.

         The  Underwriters  severally  and not jointly agree that, as an interim
measure  during the  pendency of any claim,  action,  investigation,  inquiry or
other  proceeding  described  in Section 8.2  hereof,  they will  reimburse  the
Company on a monthly basis for all reasonable  legal or other expenses  incurred
in  connection  with   investigating  or  defending  any  such  claim,   action,
investigation,  inquiry or other  proceeding,  notwithstanding  the absence of a
judicial   determination  as  to  the  propriety  and   enforceability   of  the
Underwriters'  obligation  to  reimburse  the Company for such  expenses and the
possibility  that such  payments  might later be held to have been improper by a
court  of  competent   jurisdiction.   To  the  extent  that  any  such  interim
reimbursement  payment  is so held to have  been  improper,  the  Company  shall
promptly return such payment to the Underwriters
                                       16
<PAGE>
together with interest,  compounded daily,  determined on the basis of the Prime
Rate. Any such interim reimbursement  payments which are not made to the Company
within  thirty (30) days of a request for  reimbursement  shall bear interest at
the Prime Rate from the date of such request.

                                   SECTION 7.

Registration  Statement  originally  filed with  respect to the Shares or to the

bankruptcy, insolvency, reorganization, moratorium or similar laws affecting the
enforceability of creditors' rights generally and subject to general  principles
of equity.

                           (f) no legal or governmental  proceedings are pending

<PAGE>

not require the consent, approval, authorization,  registration or qualification
of or with any  governmental  authority,  except such as have been  obtained and
such as may be required  under state  securities  or blue sky laws,  or conflict
with or result in a breach or violation of any of the terms and  provisions  of,
or constitute a default under, any indenture,  mortgage, deed of trust, lease or
other agreement or instrument,  known to such counsel, to which the Company is a
party or by  which  the  Company  or any of its  properties  are  bound,  or the
Certificate  of  Incorporation  or Bylaws of the Company,  or any statute or any
judgment,  decree,  order, rule or regulation of any court or other governmental

                           (i) the Registration Statement is effective under the

threatened or contemplated by the Commission;
    
                           (j) the Registration Statement and the Prospectus and
each  amendment or  supplement  thereto (in each case,  other than the financial

Investment Company Act of 1940, as amended; and

                           (l) such  counsel  shall also state that they have no
reason to believe that the  Registration  Statement,  as of its effective  date,
contained  any  untrue  statement  of a  material  fact or  omitted to state any
material fact required to be stated  therein or necessary to make the statements
therein not  misleading  or that the  Prospectus,  as of its date or the date of
such  opinion,  included or includes any untrue  statement of a material fact or
omitted  or  omits  to  state a  material  fact  necessary  in order to make the
statements  therein,  in light of the circumstances  under which they were made,
not  misleading;  provided  that in each case such  counsel need not express any
opinion as to the  financial  statements  and other  financial  and  statistical
information contained therein.

the extent such counsel deems proper, on certificates of responsible officers of
the Company and public  officials.  The foregoing  opinion may be limited to the
laws of the  United  States,  the laws of the State or Arizona  and the  General
Corporation  Law of the State of Delaware.  With  respect to certain  regulatory
compliance  issues,  such  counsel  may  rely on the  opinion  of Bass &  Ullman
described in Section  7.3.  References  to the  Registration  Statement  and the
Prospectus in this Section 7.2 shall include any
    
                                       19
<PAGE>
amendment or supplement thereto at the date of such opinion.  Such counsel shall
permit Luce, Forward,  Hamilton & Scripps to rely upon such opinion in rendering
its opinion in Section 7.4.

   
                           7.3 Opinion of Special Counsel.  The  Representatives
shall have  received an opinion  dated the Firm Closing  Date, of Bass & Ullman,
New York, New York, Special
    
Counsel for the Company, to the effect that:

                           (a) The  Company's  advertisements  and packaging for
its products comply in all material  respects with applicable  federal and state
regulations.

                           (b)  The  Company  has  received  all   certificates,
authorizations and permits issued by the appropriate  federal,  state or foreign
regulatory  authorities  necessary  for the conduct of its  business,  including
without  limitation  the  Food  and  Drug  Administration,   the  Federal  Trade
Commission, the Consumer Product Safety Commission, the United States Department
of  Agriculture,   the  United  States  Postal  Service  and  the  Environmental
Protection  Agency,  and the Company has not received any notice of  proceedings
relating  to  the   revocation  or   modification   of  any  such   certificate,
authorization or permit which, singly or in the aggregate,  if the subject of an
unfavorable  decision,  ruling or finding,  would  result in a material  adverse
change in the condition (financial or otherwise),  business prospects, net worth
or results of operations of the Company,  except as described in or contemplated
by the  Registration  Statement.  Each  approval,  registration,  qualification,
license,  permit, consent,  order,  authorization,  designation,  declaration or
filing by or with any regulatory,  administrative or other  governmental body or
agency necessary in connection with the execution and delivery by the Company of
this Agreement and the  consummation of the  transactions  contemplated has been
obtained or made and each is in full force and effect.

                           (c) The  Company  is not in  violation  of any  laws,
ordinances,  governmental  rules or  regulations  relating to federal,  state or
foreign  regulatory  authorities  necessary  for the  conduct  of its  business,
including without limitation the Food and Drug Administration, the Federal Trade
Commission, the Consumer Product Safety Commission, the United States Department
of  Agriculture,   the  United  States  Postal  Service  and  the  Environmental
Protection  Agency which would have a material  adverse  effect on the condition
(financial or otherwise), business, properties,  prospects, net worth or results
of operations of the Company.

                           (d) such  counsel  shall also state that they have no
reason to believe that the provisions of the  Registration  Statement  under the
captions entitled "PROSPECTUS SUMMARY -- The Company",  "RISK FACTORS -- Absence
of Clinical Studies and Scientific Review", "-- Effect of Discontinued Product",
"-- Difficulty in Product  Positioning",  "-- Uncertainty and Potential Negative
Effects of Government  Regulations;  Non-Compliance," and "BUSINESS "--Products"
and " --  Proprietary  Rights:  Trade  Name,  Trademarks  and  Copyrights",  and
"--Government  Regulation"  as of  its  effective  date,  contained  any  untrue
statement of a material  fact or omitted to state any material  fact required to
be stated therein or necessary to make the statements  therein not misleading or
that the  Prospectus,  as of its date or the date of such  opinion,  included or
includes any untrue  statement of a material fact or omitted or omits to state a
material fact necessary
                                       20
<PAGE>
in order to make the statements  therein,  in light of the  circumstances  under
which they were made,  not  misleading;  provided that in each case such counsel
need not express any opinion as to the financial  statements and other financial
and statistical information contained therein.
   
                  7.4 Review by and  Opinion of  Representatives'  Counsel.  The
Representatives shall have received an opinion,  dated the Firm Closing Date, of
Luce,  Forward,  Hamilton & Scripps LLP, counsel for the  Representatives,  with
respect to certain matters as the Representatives  may reasonably  require,  and
the Company shall have furnished to such counsel such documents and certificates
as they may  reasonably  request for the  purpose of enabling  them to pass upon
such matters.

                  7.5  Accountant's  Letter.  The  Representatives   shall  have
received from Coopers & Lybrand L.L.P. a letter or letters dated,  respectively,
the date hereof and the Closing Date, in form and substance  satisfactory to the
Representatives, to the effect that:
    

                           (a) they are independent  accountants with respect to
the Company within the meaning of the Act and the Rules and Regulations;

                           (b)  in  their  opinion,   the  financial  statements
audited by them and included in the  Registration  Statement and the  Prospectus
comply  in  form  in  all  material  respects  with  the  applicable  accounting
requirements of the Act and the related published rules and regulations;

                           (c)  on  the  basis  of  a  reading  of  the  audited
financial  statements of the Company,  for the year ended May 31, 1996,  and the
unaudited  financial  statements of the Company for the period ended [August 31,
1996], and the notes thereto,  carrying out certain specified  procedures (which
do not constitute an audit made in accordance with generally  accepted  auditing
standards)  that  would not  necessarily  reveal  matters of  significance  with
respect to the  comments  set forth in this  paragraph,  a reading of the minute
books of the shareholders,  the board of directors and any committees thereof of
the  Company,  and  inquiries  of  certain  officials  of the  Company  who have
responsibility  for  financial  and  accounting  matters,  nothing came to their
attention that caused them to believe that:

                                       (i)  the  unaudited  condensed  financial
statements  of the  Company  included  in the  Registration  Statement  and  the
Prospectus do not comply in form in all material  respects  with the  applicable
accounting  requirements  of  the  Act  and  the  related  published  rules  and
regulations  thereunder  or  are  not  in  conformity  with  generally  accepted
accounting  principles applied on a basis substantially  consistent with that of
the audited financial statements included in the Registration  Statement and the
Prospectus; and

                                       (ii) at a  specific  date not  more  than
five business  days prior to the date of such letter,  there were any changes in
the capital stock or long-term debt of the Company
                                       21
<PAGE>
or any decreases in net current assets or  stockholders'  equity of the Company,
in each case  compared with amounts shown on the [August 31, 1996] balance sheet
included in the  Registration  Statement and the  Prospectus,  or for the period
from  [August 31,  1996] to such  specified  date there were any  decreases,  as
compared  with the  corresponding  period in the  preceding  year, in net sales,
gross profit, selling, general and administrative  expenses,  employee plans and
bonuses, income (loss) from operations,  interest expenses, income (loss) before
income taxes,  provision  (benefit)  for income taxes,  net income (loss) or net
income  (loss) per share of the Company,  except in all  instances  for changes,
decreases or increases set forth in such letter; and

                           (d)  they  have   carried   out   certain   specified
procedures,  not  constituting  an  audit,  with  respect  to  certain  amounts,
percentages  and  financial  information  that  are  derived  from  the  general
accounting records of the Company and are included in the Registration Statement
and the  Prospectus,  and have compared such amounts,  percentages and financial
information with such records of the Company and with  information  derived from
such records and have found them to be in agreement,  excluding any questions of
legal interpretation.
   
         In the  event  that the  letters  referred  to above set forth any such
changes,  decreases  or  increases,  it  shall  be a  further  condition  to the
obligations  of the  Underwriters  that such letters shall be  accompanied  by a
written  explanation of the Company as to the significance  thereof,  unless the
Representatives deems such explanation unnecessary,  and such changes, decreases
or  increases  do not,  in the sole  judgment  of the  Representatives,  make it
impractical  or  inadvisable  to proceed  with the  purchase and delivery of the

Date; the Registration  Statement,  as amended as of the Firm Closing Date, does

Company has not sustained any material loss or interference with its business or
properties from fire, flood, hurricane,  accident or other calamity,  whether or

(financial or otherwise), business prospects, net worth or results of operations
of the  Company,  except in each case as  described  in or  contemplated  by the
Prospectus (exclusive of any amendment or supplement thereto).

                  7.7 NASD  Review.  The NASD,  upon  review of the terms of the
public offering of the Firm Shares and Option Shares, shall not have objected to
the Underwriters' participation in such offering.
   
                  7.8 Lockups. The Representatives shall have received from each
officer  and  director  who owns  the  Company's  Common  Stock,  or  securities
convertible  into Common Stock, an agreement to the effect that such person will
not,  directly  or  indirectly,   without  the  prior  written  consent  of  the
Representatives,  offer,  sell or grant any  option  to  purchase  or  otherwise
dispose (or  announce any offer,  sale,  grant of an option to purchase or other

satisfied with the results of their respective due diligence investigations.

                  7.10 Blue Sky Qualification.  The Shares shall be qualified in
such states as the  Representatives  may reasonably  request pursuant to Section
5.4, and each such qualification  shall be in effect and not subject to any stop
order or other  proceeding  on the Closing Date or Option  Closing  Date, as the
case may be.

                  7.10 Other Documents.  On or before the Firm Closing Date, the
Representatives  and counsel for the  Representatives  shall have  received such
further certificates, documents or other information as they may have reasonably
requested from the Company.

         All opinions, certificates, letters and documents delivered pursuant to
this  Agreement  will  comply  with  the  provisions  hereof  only if  they  are
reasonably  satisfactory in all material  respects to the  Representatives.  The
Company shall furnish to the
    
                                       23
<PAGE>
   
Representatives  such conformed copies of such opinions,  certificates,  letters
and documents in such quantities as the  Representatives  and the counsel to the
Representatives shall reasonably request.

         The respective  obligations of the several Underwriters to purchase and

                                   SECTION 8.
                        Indemnification and Contribution

                  8.1   Indemnification  by  Company.   The  Company  agrees  to
indemnify  and hold  harmless  each  Underwriter  and each  person,  if any, who
controls any Underwriter  within the meaning of Section 15 of the Act or Section
20 of the  Securities  Exchange  Act of 1934 (the  "Exchange  Act")  against any
losses,  claims,  damages  or  liabilities,  joint or  several,  to  which  such
Underwriter  or such  controlling  person may become  subject under the Act, the
Exchange  Act  or  otherwise,   insofar  as  such  losses,  claims,  damages  or
liabilities (or actions in respect thereof) arise out of or are based upon:

                           (a) any untrue  statement or alleged untrue statement
made by the Company in Section 2 of this Agreement;

   
                           (b) any untrue  statement or alleged untrue statement
of  any  material  fact  contained  in (i)  the  Registration  Statement  or any
amendment  thereto  or  any  Preliminary  Prospectus  or the  Prospectus  or any
amendment or supplement thereto,  or (ii) any application or other document,  or
any  amendment  or  supplement  thereto,  executed by the Company and based upon
written  information  furnished  by or on  behalf  of the  Company  filed in any
jurisdiction  in order to qualify the Shares  under the  securities  or blue sky
laws  thereof or filed with the  Commission  or any  securities  association  or
securities exchange (each an "Application"); or
    

                           (c) the omission or alleged  omission to state in the
Registration  Statement or any amendment thereto, any Preliminary  Prospectus or
the  Prospectus  or any amendment or supplement  thereto,  or any  Application a
material fact required to be stated  therein or necessary to make the statements
therein not misleading in light of the circumstances in which they are made, and
will reimburse,  as incurred,  each Underwriter and each such controlling person
for any legal or other expenses  reasonably incurred by such Underwriter or such
controlling  person in  connection  with  investigating,  defending  against  or
appearing as a  third-party  witness in  connection  with any such loss,  claim,
damage,  liability or action;  provided,  however,  that the Company will not be
liable in any such  case to the  extent  that any such  loss,  claim,  damage or
liability  arises out of or is based upon any untrue statement or alleged untrue
statement or omission
                                       24
<PAGE>
   
or  alleged  omission  made  in such  registration  statement  or any  amendment
thereto,  any  Preliminary  Prospectus  or the  Prospectus  or any  amendment or
supplement  thereto,  or any Application in reliance upon and in conformity with
written  information  furnished  to the Company by any  Underwriter  through the
Representatives  specifically for use therein;  and provided  further,  that the
Company will not be liable to any  Underwriter  or any person  controlling  such
Underwriter  with respect to any such untrue  statement or omission  made in any
Preliminary  Prospectus that is corrected in the Prospectus (or any amendment or
supplement  thereto) if the person  asserting  any such loss,  claim,  damage or
liability  purchased  Shares from such  Underwriter  but was not sent or given a
copy of the  Prospectus (as amended or  supplemented),  other than the documents
incorporated by reference therein at or prior to the written confirmation of the
sale of such  Shares  to such  person in any case  where  such  delivery  of the
Prospectus  (as amended or  supplemented)  is  required by the Act,  unless such
failure to deliver the Prospectus (as amended or  supplemented)  was a result of
noncompliance by the Company with Section 5.5 of this Agreement.  This indemnity
agreement  will be in addition to any liability  which the Company may otherwise
have.  The  Company  will  not,  without  the  prior  written  consent  of  each
Underwriter, settle or compromise or consent to the entry of any judgment in any
pending or  threatened  claim,  action,  suit or  proceeding in respect of which
indemnification  may be sought hereunder (whether or not such Underwriter or any
person who controls such Underwriter within the meaning of Section 15 of the Act
or Section 20 of the  Exchange  Act is a party to such  claim,  action,  suit or
proceeding),   unless  such  settlement,   compromise  or  consent  includes  an
unconditional  release of such Underwriter and each such controlling person from
all liability arising out of such claim, action, suit or proceeding.

                  8.2  Indemnification  by  Underwriters.  Each Underwriter will
indemnify  and hold  harmless the Company,  each of its  directors,  each of its
officers who signed the  Registration  Statement  and each  person,  if any, who
controls  the Company  within the meaning of Section 15 of the Act or Section 20
of the Exchange Act against any losses,  claims, damages or liabilities to which
the Company, any such director or officer of the Company or any such controlling
person of the Company may become  subject  under the Act,  the  Exchange  Act or
otherwise, insofar as such losses, claims, damages or liabilities (or actions in
respect  thereof)  arise out of or are based  upon (a) any untrue  statement  or
alleged  untrue  statement of any material  fact  contained in the  Registration
Statement or any amendment thereto, any Preliminary Prospectus or the Prospectus
or any amendment or supplement  thereto,  or any Application or (b) the omission
or the alleged  omission to state  therein a material fact required to be stated
in  the  Registration  Statement  or  any  amendment  thereto,  any  Preliminary
Prospectus or the  Prospectus or any  amendment or  supplement  thereto,  or any
Application or necessary to make the statements  therein not misleading in light
of the  circumstances  in which they are made,  in each case to the extent,  but
only to the extent,  that such untrue  statement or alleged untrue  statement or
omission or alleged  omission was made in reliance upon and in  conformity  with
written  information  furnished  to the Company by any  Underwriter  through the
Representatives specifically for use therein; and, subject to the limitation set
forth immediately preceding this clause, will reimburse,  as incurred, any legal
or other expenses reasonably incurred by the Company or any director, officer or
controlling  person of the Company in connection with investigation or defending
against or appearing as a third-party  witness in connection with any such loss,
claim, damage, liability or any action in respect thereof. This
    
                                       25
<PAGE>
indemnity  agreement will be in addition to any liability which such Underwriter
may otherwise  have. No Underwriter  will,  without the prior written consent of
the Company, settle or compromise or consent to the entry of any judgment in any
pending or  threatened  claim,  action,  suit or  proceeding in respect of which
indemnification may be sought hereunder (whether or not the Company,  any of its
directors,  any of its  officers  who signed the  Registration  Statement or any
person who controls  the Company  within the meaning of Section 15 of the Act or
Section  20 of the  Exchange  Act is a party  to  such  claim,  action,  suit or
proceeding),   unless  such  settlement,   compromise  or  consent  includes  an
unconditional  release  of the  Company  and each  such  director,  officer  and
controlling person from all liability arising out of such claim, action, suit or
proceeding.
   
                  8.3  Notice  of  Defense.   Promptly   after   receipt  by  an
indemnified  party  under this  Section 8 of notice of the  commencement  of any
action, such indemnified party will, if a claim in respect thereof is to be made
against the  indemnifying  party under this  Section 8, notify the  indemnifying
party  of  the  commencement   thereof;  but  the  omission  so  to  notify  the
indemnifying  party will not relieve it from any liability  which it may have to
any  indemnified  party  otherwise  than under this  Section 8. In case any such
action  is  brought  against  any  indemnified   party,   and  it  notifies  the
indemnifying party of the commencement  thereof,  the indemnifying party will be
entitled to  participate  therein  and, to the extent that it may wish,  jointly
with  any  other  indemnifying  party  and  the  indemnified  party  shall  have
reasonably  concluded that there may be one or more legal defenses  available to
it and/or other  indemnified  parties which are different  from or additional to
those available to the indemnifying party, the indemnifying party shall not have
the right to direct  the  defense of such  action on behalf of such  indemnified
party or parties and such  indemnified  party or parties shall have the right to
select  separate  counsel to defend  such  action on behalf of such  indemnified
party or parties.  After notice from the indemnifying  party to such indemnified
party of its  election  so to assume the defense  thereof  and  approval by such
indemnified party of counsel  appointed to defend such action,  the indemnifying
party  will  not  be  liable  to  such  indemnified  party  (which  may  not  be
unreasonably  withheld or delayed)  under this  Section 8 for any legal or other
expenses, other than reasonable costs of investigation, subsequently incurred by
such indemnified  party in connection with the defense  thereof,  unless (a) the
indemnified  party shall have employed  separate  counsel in accordance with the
proviso to the next preceding  sentence (it being understood,  however,  that in
connection with such action the  indemnifying  party shall not be liable for the
expenses of more than one separate  counsel at any one time in any one action or
separate but substantially  similar actions in the same jurisdiction arising out
of  the  same  general   allegations   or   circumstances,   designated  by  the
Representatives in the case of Section 8.1, representing the indemnified parties
under such  Section  8.1 who are  parties to such  action or actions) or (b) the
indemnifying  party has authorized the employment of counsel for the indemnified
party at the  expense of the  indemnifying  party.  After such  notice  from the
indemnifying party to such indemnified party, the indemnifying party will not be
liable for the costs and expenses of any  settlement of such action  effected by
such  indemnified  party without the consent of the indemnifying  party,  unless
such indemnified  party waived its rights under this Section 8 in which case the
indemnified party may effect such a settlement without such consent.

                  8.4  Contribution.  In  circumstances  in which the  indemnity
agreement  provided  for  in the  preceding  paragraphs  of  this  Section  8 is
unavailable or insufficient to hold harmless an indemnified  party in respect of
any losses, claims,  damages or liability (or actions in respect thereof),  each
indemnifying  party,  in order to provide for just and  equitable  contribution,
shall  contribute to the amount paid or payable by such  indemnified  party as a
result of such losses,  claims,  damages or  liabilities  (or actions in respect
thereof)  in such  proportion  as is  appropriate  to reflect  (a) the  relative
benefits  received by the indemnifying  party or parties on the one hand and the
indemnified  party on the other  from the  offering  of the Shares or (b) if the
allocation  provided by the foregoing  clause (a) is not permitted by applicable
law,  not  only  such  relative  benefits  but also  the  relative  fault of the
indemnifying  party or parties on the one hand and the indemnified  party on the
other in connection  with the  statements or omissions or alleged  statements or
omissions that resulted in such losses,  claims, damages or liability (or action
in respect  thereof).  The relative  benefits received by the Company on the one
hand  and the  Underwriters  on the  other  shall  be  deemed  to be in the same
proportion as the total proceeds from the offering  (after  deducting  expenses)
received by the Company bear to the total underwriting discounts and commissions
received  by the  Underwriters.  The  relative  fault  of the  parties  shall be
determined by reference  to, among other  things,  whether the untrue or alleged
untrue statement of a material fact or the omission or alleged omission to state
a  material  fact  relates  to  information  supplied  by  the  Company  or  the
Underwriters,  the parties' relative intents,  knowledge,  access to information
and opportunity to correct or prevent such statement or omission,  and any other
equitable considerations  appropriate in the circumstances.  The Company and the
Underwriters  agree  that  it  would  not be  equitable  if the  amount  of such
contribution  were determined by pro rata or per capita  allocation (even if the
Underwriters were treated as one entity for such purpose) or by any other method
of  allocation  that  does not take into  account  the  equitable  consideration
referred to in the first sentence of this Section 8.4. Notwithstanding any other
provision  of this  Section  8.4,  no  Underwriter  shall be  obligated  to make
contributions hereunder that in the aggregate exceed the underwriter discount on
the  Shares  purchased  by such  Underwriter  under  this  Agreement,  less  the
aggregate  amount  of any  damages  that such  Underwriter  has  otherwise  been
required to pay in respect of the same or any  substantially  similar claim, and
no person guilty of fraudulent  misrepresentation (within the meaning of Section
11(f) of the Act) shall be entitled to contribution  from any person who was not
guilty of such fraudulent  misrepresentation.  The Underwriters'  obligations to
contribute hereunder are several in proportion to their respective  underwriting
obligations  and not  joint,  and  contributions  among  Underwriters  shall  be
governed by the provisions of the Agreement Among Underwriters.  For purposes of
this Section 8.4, each person,  if any, who controls an  Underwriter  within the
meaning of Section  15 of the Act or Section 20 of the  Exchange  Act shall have
the same rights to  contribution as such  Underwriter,  and each director of the
Company,  each officer of the Company who signed the Registration  Statement and
each person,  if any, who controls the Company  within the meaning of Section 15
of the Act or  Section  20 of the  Exchange  Act,  shall  have the same right to
contribution as the Company as the case may be.

                                   SECTION 9.
                             Default of Underwriters
   
         If one or more  Underwriters  default in their  obligations to purchase
Firm Shares,  or Option Shares hereunder and the aggregate number of such Shares
that such defaulting  Underwriter or Underwriters  agreed but failed to purchase
is ten percent or less of the  aggregate  number of Firm Shares or Option Shares
to be purchased by all of the  Underwriters  at such time  hereunder,  the other
Underwriters may make arrangements  satisfactory to the  Representatives for the
purchase  of such  Shares by other  persons  (who may include one or more of the
non-defaulting  Underwriters,  including  the  Representatives),  but if no such
arrangements  are made by the Firm  Closing Date or the related  Option  Closing
Date, as the case may be, the other Underwriters shall be obligated severally in
proportion  to their  respective  commitments  hereunder  to  purchase  the Firm
Shares, or Option Shares that such defaulting Underwriter or Underwriters agreed
but failed to purchase.  In the event of any default by one or more Underwriters
as  described  in this  Section 9, the  Representatives  shall have the right to
postpone the Firm Closing Date or the Option  Closing  Date, as the case may be,
established  as  provided  in Section 3 hereof for not more than seven  business
days in order that any  necessary  changes  may be made in the  arrangements  or
documents for the purpose and delivery of the Firm Shares or Option  Shares,  as
the case may be. As used in this Agreement,  the term "Underwriter" includes any
persons  substituted  for an  Underwriter  under this Section 9. Nothing  herein
shall relieve any defaulting Underwriter from liability for its default.

                                    Survival

         The  respective  representations,  warranties,  agreements,  covenants,
indemnities and other statements of the Company,  its officers and directors and
the several  Underwriters set forth in this Agreement or made by or on behalf of
them,  respectively,  pursuant to this Agreement  shall remain in full force and
effect, regardless of (a) any investigation made by or on behalf of the Company,
any of its officers or directors,  any  Underwriter  or any  controlling  person
referred to in Section 8 hereof and (b)  delivery of and payment for the Shares.
The respective agreements, covenants, indemnities and other statements set forth
in Sections 5 and 8 hereof shall remain in full force and effect,  regardless of
any termination or cancellation this Agreement.

                                   SECTION 11.
                                   Termination
   
                  11.1 By Representatives. This Agreement may be terminated with
respect to the Firm Shares or any Option  Shares in the sole  discretion  of the
Representatives by notice to the Company given prior to the Firm Closing Date or
the related  Option  Closing Date,  respectively,  in the event that the Company
shall have failed, refused or been unable to perform all obligations and satisfy
all  conditions  on its part to be performed or satisfied  hereunder at or prior
thereto or, if at or prior to the Firm Closing date or such Option Closing Date,
respectively:

                           (a) the Company  shall have  sustained  any  material
loss  or  interference  with  its  business  or  properties  from  fire,  flood,
hurricane,  accident or other calamity,  whether or not covered by insurance, or
from any labor  dispute or any legal or  governmental  proceeding or there shall
have  been  any  material  adverse  change,  or  any  development   involving  a
prospective material adverse change (including  financial or otherwise),  in the
business prospects, net worth or results of operations of the Company, except in
each case as described in or  contemplated  by the Prospectus  (exclusive of any
amendment or supplement thereto);
    
                           (b)  trading  in the  Common  Stock  shall  have been
suspended by the Commission or the National  Association  of Securities  Dealers
Automated  Quotation  National Market or trading in securities  generally on the
New York Stock Exchange or the American Stock Exchange shall have been suspended
or minimum or maximum prices shall have been established on any such exchange or
market system;

                           (c) a banking  moratorium shall have been declared by
New York, Arizona, or United States authorities; or
                                       29
<PAGE>
   
                           (d)  there   shall  have  been  (i)  an  outbreak  or
escalation of hostilities  between the United States and any foreign power, (ii)
an outbreak or escalation of any other  insurrection or armed conflict involving
the United States or (iii) any other  calamity or crisis having an effect on the
financial markets that, in the reasonable judgment of the Representatives, makes
it  impracticable  or  inadvisable  to proceed  with the public  offering or the
delivery of the Shares as contemplated by the Registration Statement, as amended
as of the date hereof.
    
                  11.2  Effect of  Termination  Hereunder.  Termination  of this
Agreement pursuant to this Section 11 shall be without liability of any party to
any other party, except as provided in Section 10 hereof.

         The  statements set forth in the last paragraph on the front cover page
and  under the  heading  "Underwriting"  in any  Preliminary  Prospectus  or the
Prospectus,  to the extent such statements relate to the Underwriters constitute
the only information furnished by any Underwriter through the Representatives to
the  Company  for the  purposes  of  Section 8 and 10 hereof.  The  Underwriters
represent and warrant to the Company that such statements,  to such extent,  are
correct as of the date hereof and at each Closing Date.

         This Agreement  shall inure to the benefit of and shall be binding upon

              Re: Form SB-2 Registration Statement

Dear Sirs:

              We refer to the  Registration  Statement  on Form  SB-2  (File No.
333-11821), as amended (the "Registration Statement"), filed by M.D. Labs, Inc.,
a  Delaware  corporation  (the  "Company"),  with the  Securities  and  Exchange
Commission  under  the  Securities  Act of 1933,  as  amended,  relating  to the
issuance and sale of up to 1,495,000 shares of the Company's Common Stock, $.001
par value per share (the "Shares"),  by the Company to the Underwriters named in
Schedule  1  to  the  Underwriting   Agreement  filed  as  Exhibit  1.1  to  the
Registration Statement (the "Underwriting Agreement").

              We have  reviewed  the  General  Corporation  Law of the  State of
Delaware and examined originals,  or copies certified or otherwise identified to
our  satisfaction,  of such documents,  and such corporate and other records and
proceedings of the Company,  and made such other  investigation and inquiries of
public officials and the officers of the Company,  as we deemed necessary to the
opinions  hereinafter  expressed.  On the basis of the foregoing,  we are of the
opinion that the Shares covered by the Registration  Statement to be sold by the
Company pursuant to the Underwriting Agreement, when issued and delivered by the
Company against payment therefor as provided in the Underwriting Agreement, will
be legally issued, fully paid and non-assessable.

              We do not find it necessary for the purposes of this opinion,  and
accordingly do not purport to cover herein, the application of the securities or
"Blue Sky" laws of the various states to the issuance and sale of the Shares.

the Registration  Statement and to the reference to our firm appearing under the

Dear Sirs:

         We have acted as special  counsel to MD Labs,  Inc. with regard to FDA,
FTC and local  licensing  matters.  In this  regard we have  reviewed  the above
described Registration Statement as regards the sections entitled RISK FACTORS -
Absence of Clinical  Studies,  Scientific  Review and Testing,  Uncertainty  and
Potential  Negative  Effects  of  Government  Regulations,   Noncompliance  with
Government  Regulations  and  Effect of  Discontinued  Product;  and  BUSINESS -

         As of the stated effective date, we have no reason to believe that such
sections  (a) contain any untrue  statement of a material  fact,  or (b) omit to
state any material fact  required to be stated  therein or necessary to make the
statements therein not misleading.

         We note that our opinion is in part based upon information  supplied to
us by the Company and its  management,  which we have  relied on.  Facsimile  or
other copies of this opinion may be used to serve as an original.

than  common  stock or  securities  of another  corporation  or other  property,
thereafter  the number of such other shares or other  securities  or property so
obtainable  shall be subject to adjustment  from time to time in a manner and on
terms as nearly  equivalent as practicable to the provisions with respect to the
Common  Stock  contained in Section , and all other  provisions  of this Warrant
with  respect to the Common  Stock  shall  apply on like terms to any such other
shares or other securities or property. Subject to the foregoing, and unless the
<PAGE>
context requires  otherwise,  all references  herein to "Common Stock" shall, in
the event of an  adjustment  pursuant to Section , be deemed to refer as well to
any  other   securities  or  property  then  obtainable  as  a  result  of  such
adjustments.

         2. Exercise of Warrant. The purchase rights represented by this Warrant
may be  exercised  by the  Warrantholder  or its  duly  authorized  attorney  or
representative,  in whole or in part (but not as to a fractional share of Common
Stock),  at any time and from time to time during the period  commencing  on the
date of this  Warrant  (the  "Commencement  Date")  and  expiring  at 5:00 p.m.,
Mountain  Standard  Time,  September 14, 2001 (the  "Expiration  Date")(or  such
earlier date as may be provided  pursuant to Section 9 herein),  or if such date
is a day on which federal or state chartered banking institutions are authorized
by law to close,  then on the next succeeding day which shall not be such a day,
upon presentation of this Warrant at the principal office of the Company,  or at
the office of its stock transfer  agent, if any, with the purchase form attached
hereto duly completed and signed,  and upon payment to the Company in cash or by
certified  check or bank draft of an amount  equal to the number of shares being
so purchased multiplied by the Warrant Price, together with all taxes applicable
upon such exercise. The Company agrees that the Warrantholder will be deemed the
record owner of such shares as of the close of business on the date on which the
Warrant  shall have been  presented  and  payment  shall have been made for such
shares as  aforesaid.  Certificates  for the shares of Common Stock so purchased
shall be delivered to the Warrantholder  within a reasonable time, not exceeding
20 days, after the exercise in full of the rights represented by this Warrant.

         If the  Warrant is  exercised  in part only,  the Company  shall,  upon
surrender of this Warrant for cancellation, deliver a new Warrant evidencing the
rights of the  Warrantholder  to  purchase  the  balance of the shares of Common
Stock which the Warrantholder is entitled to purchase hereunder.

         3. Vesting Schedule.  Subject to Section 9 herein,  the purchase rights
represented by this Warrant shall become exercisable  according to the following
schedule:  warrants to acquire 7,000 shares of Common Stock shall be exercisable
at  September  14, 1997;  and  warrants to acquire  7,000 shares of Common Stock
shall be exercisable at September 14, 1998.

         4. Certain Adjustments to Warrant.

                  (a) In case the Company  shall (i) pay a dividend in shares of
Common Stock or make a  distribution  in shares of Common Stock,  (ii) subdivide
its outstanding  shares of Common Stock, (iii) combine its outstanding shares of
Common  Stock into a smaller  number of shares of Common  Stock or (iv) issue by
reclassification
                                        2
<PAGE>
of its shares of Common Stock other  securities  of the  Company,  the number of
shares of Common Stock  purchasable  upon  exercise of this Warrant  immediately
prior thereto shall be adjusted so that the  Warrantholder  shall be entitled to
receive the kind and number of shares of Common Stock or other securities of the
Company  which he would  have  owned or have been  entitled  to  receive  at the
happening of any of the events  described above, had such Warrant been exercised
immediately prior to the happening of such event or any record date with respect
thereto.  An  adjustment  made  pursuant  to this  paragraph  (a)  shall  become
effective  immediately after the effective date of such event retroactive to the
record date, if any, for such event.

                  (b) Whenever the number of shares of Common Stock  purchasable
upon the exercise of this Warrant is adjusted,  as herein provided,  the Warrant
Price shall be adjusted by multiplying such Warrant Price  immediately  prior to
such  adjustment by a fraction,  of which the  numerator  shall be the number of
shares of Common Stock purchasable upon the exercise of this Warrant immediately
prior to such  adjustment,  and of which the denominator  shall be the number of
shares of Common Stock so purchasable immediately thereafter.

                  (c) In the event of any adjustment  pursuant to this Section ,
no  fractional  shares of Common  Stock shall be issued in  connection  with the
exercise of any  Warrants,  but the Company  shall,  in lieu of such  fractional
shares, make such cash payment therefor on the basis of the current market price
on the day immediately prior to exercise.

                  (d)  Irrespective of any adjustments  pursuant to this Section
to the Warrant Price or to the number of shares or other  securities  obtainable
upon  exercise of this  Warrant,  this Warrant may continue to state the Warrant
Price and the number of shares  obtainable upon exercise,  as the same price and
number of shares stated herein.

         5. Merger.  In the event of a merger,  consolidation or  reorganization
with another corporation in which the Company is not the surviving  corporation,
the Company  (subject to the approval of the Board) or the board of directors of
any  corporation  assuming the  obligations of the Company  hereunder shall take
action pursuant to either clause (a) or (b) below:

                           (a)  Appropriate   provision  may  be  made  for  the
protection  of  this  Warrant  by the  substitution  on an  equitable  basis  of
appropriate shares of the surviving corporation, provided that the excess of the
aggregate fair market value (as determined by the Company) of the shares subject
to this Warrant  immediately  before such  substitution  over the exercise price
hereof is not more than the excess of the aggregate fair market value of the
                                        3
<PAGE>
substituted shares made subject to purchase  immediately after such substitution
over the exercise price thereof; or

                           (b)  Appropriate   provision  may  be  made  for  the
cancellation  of this Warrant.  In such event,  the Company,  or the corporation
assuming  the  obligations  of the  Company  hereunder,  shall pay the Holder an
amount  of cash  (less  normal  withholding  taxes)  equal to the  excess of the
highest fair market value per share of the Common Stock during the 60-day period
immediately  preceding  the merger,  consolidation  or  reorganization  over the
exercise  price,  multiplied  by the number of shares  subject  to this  Warrant
(whether or not then exercisable).

         6. Covenants of the Company. The Company covenants and agrees that:

                  (a) During the period within which the rights  represented  by
the Warrant may be  exercised,  the Company  will at all times  reserve and keep
available,  free from  preemptive  rights out of the aggregate of its authorized
but  unissued  Common  Stock,  for the  purpose of  enabling  it to satisfy  any
obligation  to issue shares of Common  Stock upon the exercise of this  Warrant,
the  number of shares of Common  Stock  deliverable  upon the  exercise  of this
Warrant.  If at any time the number of shares of  authorized  Common Stock shall
not be sufficient to effect the exercise of this Warrant,  the Company will take
such  corporate  action as may be  necessary  to  increase  its  authorized  but
unissued  Common Stock to such number of shares as shall be sufficient  for such
purpose. The Company shall have analogous  obligations with respect to any other
securities or properties  issuable upon exercise of this Warrant.  The Company's
issuance of this Warrant shall constitute full authority to its officers who are
charged with the duty of executing  stock  certificates to execute and issue the
necessary  certificates  for shares of Common  Stock upon the  exercise  of this
Warrant;

                  (b) All Common  Stock that may be issued upon  exercise of the
rights represented by this Warrant will, upon issuance, be validly issued, fully
paid, nonassessable, and free from all taxes, liens, and charges with respect to
the issue thereof; and

                  (c) All  original  issue  taxes  payable  with  respect to the
issuance of shares upon the exercise of the rights  represented  by this Warrant
will be borne by the Company but in no event will the Company be  responsible or
liable for income taxes or transfer taxes upon the transfer of any Warrant.

         7. No  Stockholder  Rights.  Until  exercised,  this Warrant  shall not
entitle the  Warrantholder to any voting rights or other rights as a stockholder
of the Company.  The rights of the Holder are limited to those expressed in this
Warrant and are not
                                        4
<PAGE>
enforceable against the Company except to the extent set forth herein.

         8. Transfer Restrictions.

                  (a) This  Warrant  is not  transferable  except by will or the
laws of descent and distribution and, during Holder's  lifetime,  it may only be
exercised by Holder.

                  (b) Neither this Warrant nor the shares of stock issuable upon
the exercise  hereof have been  registered  under the Securities Act of 1933, as
amended (the "Securities  Act") or under any state securities laws and unless so
registered may not be  transferred,  sold,  pledged,  hypothecated  or otherwise
disposed of unless an exemption  from such  registration  is  available.  In the
event Holder  desires to transfer  any of the shares of stock issued  hereunder,
the Holder must give the Company prior written notice of such proposed  transfer
including the name and address of the proposed transferee.  Such transfer may be
made only either (i) upon publication by the Securities and Exchange  Commission
(the  "Commission") of a ruling,  interpretation,  opinion or "no action letter"
based upon  facts  presented  to said  Commission,  or (ii) upon  receipt by the
Company of an opinion  of  counsel to the  Company in either  case to the effect
that the proposed  transfer will not violate the  provisions  of the  Securities
Act,  the  Securities  Exchange  Act of  1934,  as  amended,  or the  rules  and
regulations  promulgated  under  either  such act, or in the case of clause (ii)
above,  to the effect  that the shares of stock to be sold or  transferred  have
been  registered  under the Securities Act and that there is in effect a current
prospectus  meeting the  requirements of Subsection 10(a) of the Securities Act,
which is being or will be delivered to the  purchaser or  transferee at or prior
to the time of delivery of the certificates evidencing the shares of stock to be
sold or transferred.

                  (c) Prior to any such  proposed  transfer,  and as a condition
thereto,  if such  transfer is not made  pursuant to an  effective  registration
statement  under the  Securities  Act,  the Holder  will,  if  requested  by the
Company,  deliver  to the  Company  (i) an  investment  covenant  signed  by the
proposed  transferee,  (ii) an agreement by such transferee to the impression of
the  restrictive  investment  legend  set  forth  herein on the  certificate  or
certificates  representing the securities acquired by such transferee,  (iii) an
agreement by such  transferee that the Company may place a "stop transfer order"
with its transfer agent or registrar, and (iv) an agreement by the transferee to
indemnify the Company to the same extent as set forth in paragraph 8(d) below.

                  (d) Holder  acknowledges  that Holder  understands the meaning
and legal  consequences  of this  Section  8, and the  Holder  hereby  agrees to
indemnify and hold harmless the Company, its
                                        5
<PAGE>
representatives  and each officer and director  thereof from and against any and
all loss, damage or liability  (including all attorneys' fees and costs incurred
in  enforcing  this  indemnity  provision)  due to or  arising  out  of (i)  the
inaccuracy  of any  representation  or the  breach  of any  warranty  of  Holder
contained in, or any other breach of, this Warrant Agreement,  (ii) any transfer
of any of this Warrant or the shares of stock issuable hereunder in violation of
the  Securities  Act, the  Securities  Exchange Act of 1934, as amended,  or the
rules and regulations  promulgated under either of such acts, (iii) any transfer
of this  Warrant  or any of said  shares  of stock not in  accordance  with this
Warrant Agreement or (iv) any untrue statement or omission to state any material
fact in connection  with the investment  representations  or with respect to the
facts and representations  supplied by the Holder to counsel to the Company upon
which its opinion as to a proposed transfer shall have been based.

                  (e) Any assignment,  transfer, pledge,  hypothecation or other
disposition of this Warrant attempted contrary to the provisions of this Warrant
Agreement, or any levy of execution,  attachment or other process attempted upon
the Warrant, shall be null and void and without effect.

                  (f) Unless the shares of stock  issuable  hereunder  have been
registered  under the Securities Act, upon exercise of this Warrant (in whole or
in part) and the issuance of any of said shares,  the Company shall instruct its
transfer  agent to enter stop transfer  orders with respect to such shares,  and
all  certificates  representing  said  shares  shall  bear on the  face  thereof
substantially the following legend, insofar as is consistent with Arizona law:

         "The shares of common stock  represented  by this  certificate
         have not been registered  under the Securities Act of 1933, as
         amended,  and may not be sold,  offered  for  sale,  assigned,
         transferred  or  otherwise   disposed  of  unless   registered
         pursuant  to the  provisions  of  that  Act or an  opinion  of
         counsel  to  the  Company  is  obtained   stating   that  such
         disposition is in compliance with an available  exemption from
         such registration."

         9. Termination of the Warrant.  Notwithstanding  anything herein to the
contrary,  this Warrant can become  exercisable only while the Holder is a party
to  the  personal  services  agreement  referred  to  above,  and  shall  not be
exercisable after the earliest of (i) September 14, 2001; (ii) a material breach
of the personal  services  agreement which, if curable,  remains uncured 10 days
after notice thereof from the Company to the Holder.
                                        6
<PAGE>
         10. No Guarantee of Services.  This Agreement  shall in no way restrict
the  right  (if any) of the  Company  or any of its  subsidiaries  to  terminate
Holder's services at any time.

         11. Lost  Certificate.  If this Warrant is lost,  stolen,  mutilated or
destroyed,  the  Company  shall,  on such terms as the  Company  may  reasonably
impose,  including a requirement that the  Warrantholder  obtain a bond, issue a
new Warrant of like denomination, tenor and date.

         12. Binding  Effect.  This Warrant shall inure to the benefit of and be
binding upon the Warrantholder,  the Company and their respective successors and
permitted assigns.

         13. Company's  Notice of Certain Events.  So long as this Warrant shall
be outstanding and unexercised (i) if the Company shall pay any dividend or make
any  distribution  upon the Common Stock,  or (ii) if the company shall offer to
the holders of Common Stock for  subscription  or purchase by them any shares of
stock of any class or any  other  rights,  or (iii) in the event of any  capital
reorganization of the Company, reclassification of the Company, reclassification
of the capital stock of the Company, consolidation or merger of the Company with
or into another  corporation,  sale, lease or transfer of shall or substantially
all of the  property  and  assets of the  Company  to  another  corporation,  or

the Holder,  at least ten days prior to the date  specified in (a) or (b) below,
as the case may be, a notice  containing  a brief  description  of the  proposed
action and stating the date on which (a) a record is to be taken for the purpose
of  such  dividend,  distribution  or  rights,  or  (b)  such  reclassification,
reorganization,   consolidation,   merger,   conveyance,   lease,   dissolution,
liquidation or winding up is to take place and the date, if any, is to be fixed,
as of which the holders of Common  Stock of record shall be entitled to exchange
their shares of Common Stock for securities or other property  deliverable  upon
such  reclassification,   reorganization,   consolidation,  merger,  conveyance,
dissolution, liquidation or winding up.

         14. Notice.  Notices and other communications to be given to the Holder
of the Warrants  evidenced by this  certificate  shall be delivered by hand,  by

         The undersigned  (the  "Subscriber")  hereby  subscribes to acquire the
number of shares of common  stock,  $0.001 par value per share (the  "Shares" or
"Share" when used in the singular) of M.D.  Labs,  Inc., a Delaware  corporation
(the  "Company" or "M.D.  Labs") set forth on the  signature  page  hereof.  The

L.L.C.,   an  Arizona  limited  liability  company  doing  business  as  Houston

in exchange for the Shares acquired hereunder (the "Assigned Units"). The number
of Shares to be received by Subscriber  for Assigned Units  exchanged  hereunder
will be at the rate of 30,000  Shares  for one (1)  Investment  Unit and will be
adjusted  proportionately  for the number of Investment  Units,  or multiples or
fractions thereof, held by Subscriber.  Such acquisition is subject to the terms
and conditions set forth in the Company's  Private Placement  Memorandum,  dated
March 4, 1996 (including all documents  incorporated therein, the "Memorandum"),

         consideration for the Shares acquired hereunder will be provided by the
         execution and delivery with this Shares  Subscription  Agreement of the
         Assignment,  as hereinafter defined,  assigning the Investment Units to

         Assignment  of Membership  Interests  and Agreement of Assignee  (Share
         Exchange) in  substantially  the form of Exhibit H-2 to the  Memorandum
         (the  "Assignment") or to do so through  Subscriber's  attorney-in-fact

         appointed successors, as Subscriber's true and lawful attorney-in-fact,
         with full power and authority to act in  Subscriber's  name,  place and
         stead to make, execute,  acknowledge, and deliver the Assignment and to

         power   of   attorney   may  be   exercised   by   one  of  the   above
         attorneys-in-fact for Subscriber by signature or by listing all holders
         of  Investment  Units  acquiring  shares of Common  Stock for whom such
         attorneys-in-fact  are acting as  attorneys-in-fact  and  executing any
         instrument  with the  signature  of such  attorneys-in-fact  acting  as
         attorneys-in-fact for all of them. The Subscriber shall be bound by all
         representations   of  the  above   attorneys-in-fact   as  Subscriber's
         attorney-in-fact  and hereby  waives any and all defenses  which may be
         available to Subscriber to contest,  negate or disaffirm the actions of
         the attorneys-in-fact or their successors under this power of attorney,
         and hereby  ratifies and confirms all acts which the  attorneys-in-fact
         or their successors hereunder may take as attorney-in-fact hereunder in
         all respects as though performed by Subscriber.

                  The pages of this  Shares  Subscription  Agreement  upon which
         this power of attorney is set forth and the pages hereof upon which the
         Subscriber's  signature  appears may be separated from the rest of this
         agreement and may be recorded as evidence of the power and authority of
         the  attorneys-in-fact  and  each of  them to  exercise  the  power  of
         attorney set forth herein.

         3.   Representations  and  Warranties.   Subscriber  hereby  makes  the
         following representations and warranties to the Company, and Subscriber
         agrees to indemnify, hold harmless, and pay all judgments of and claims
         against the Company from any  liability or injury,  including,  but not
         limited  to,  that  arising  under  Federal or state  securities  laws,
         incurred as a result of any misrepresentation  herein or any warranties
         not performed by Subscriber.

                  (a) Subscriber owns the Assigned Units entirely free and clear
         of any and all judgments, actions, claims, charges, liabilities,  liens
         or encumbrances  of any kind or nature  whatsoever  (collectively,  the
         "Claims"). Subscriber has not pledged any portion of the Assigned Units
         as collateral for any loans,  and has good and marketable  title to the
         Assigned Units.  Subscriber has the complete and unrestricted power and
         the unqualified right to sell, assign, transfer,  convey and deliver to
         the Company title to the Assigned Units, entirely free and clear of any
         and all Claims.  Upon the date of assignment of the Assigned  Units and
         the  consummation  of this  transaction,  Subscriber  shall be the sole
         owner of the  Assigned  Units,  entirely  free and clear of any and all

                  (b)  Subscriber  is the sole and true party in interest and is
         not acquiring for the benefit of any other person;

                  (c)  Subscriber has read,  analyzed,  and is familiar with the
         Memorandum  and has  retained  copies of the  Memorandum,  this  Shares
         Subscription Agreement, and the Investor Suitability Questionnaire;

                  (d)  Subscriber has read,  analyzed,  and is familiar with the
         section of the  Memorandum  entitled  "WHO MAY INVEST"  and  Subscriber
         hereby warrants that Subscriber is an Accredited  Investor,  as defined
         therein;

                  (e)  Subscriber   understands  that  all  books,  records  and
         documents  of the  Company  relating to this  investment  have been and
         remain  available for inspection by Subscriber upon reasonable  notice.
         Subscriber  confirms  that all documents  requested by Subscriber  have
         been made available,  and that Subscriber has been supplied with all of
         the additional  information  concerning  this  investment that has been
         requested.  In making a decision to acquire the Shares,  Subscriber has

         the Company;

                  (f)  Subscriber  is aware that an  investment in the Shares is
         highly  speculative  and subject to  substantial  risks.  Subscriber is
         capable of bearing the high degree of economic risk and burdens of this
         venture, including, but not limited to, the possibility of the complete
         loss of all funds  invested,  the loss of any anticipated tax benefits,
         the lack of a public market, and limited  transferability of the Shares
         which may make the  liquidation of this  investment  impossible for the
         indefinite future;

         Subscriber by the Company  through the Memorandum in such a manner that

         Company,  or a person  acting on its behalf,  concerning  the terms and
         conditions of this  transaction.  At no time was  Subscriber  presented
         with  or  solicited  by  or  through  any  article,   notice  or  other
         communication  published  in any  newspaper  or other  leaflet,  public
         promotional   meeting,   television,   radio  or  other   broadcast  or
         transmittal advertisement or any other form of general advertising;

                  (h) Subscriber, if a corporation,  partnership, trust or other
         entity,  is  authorized  and duly  empowered  to  acquire  and hold the
         Shares, has its principal place of business at the address set forth on
         the signature page and has not been formed for the specific  purpose of
         acquiring the Shares;

                  (i) The Shares are being acquired solely for  Subscriber's own
         account, for investment,  and are not being acquired with a view to the
         resale, distribution, subdivision or fractionalization thereof;

                  (j)  Subscriber  understands  that  the  Shares  have not been
         registered  under the Securities Act of 1933, as amended (the "Act") or
         any other  state  securities  laws in  reliance  upon  exemptions  from
         registration for non-public offerings.  Subscriber understands that the
         Shares or any  interest  therein may not be, and agrees that the Shares
         or any interest therein,  will not be, resold or otherwise  disposed of
         by Subscriber  unless the Shares are subsequently  registered under the
         Act and under  appropriate  state securities laws or unless the Company
         receives  an opinion of counsel  satisfactory  to it that an  exemption
         from registration is available;

                  (k)  Subscriber  has  been  informed  of and  understands  the
         following:

                       (i) The Company's balance sheet is unaudited,  management
                  prepared and pro forma,

                       (ii)   There   are   substantial   restrictions   on  the
                  transferability of the Shares unless they are registered under
                  the Act; and

                       (iii) No federal or state  agency has made any finding or
                  determination  as to the  fairness  of the  Shares  for public
                  investment  nor  any  recommendation  or  endorsement  of  the
                  Shares;

         following  information  has  ever  been  represented,   guaranteed,  or
         warranted to Subscriber expressly or by implication, by any broker, the
         Company,  or  agents or  employees  of the  foregoing,  or by any other
         person;

                       (i)  The   approximate  or  exact  length  of  time  that
                  Subscriber will be
                  required to hold the Shares;

                       (ii) The percentage of profit and/or amount of or type of
                  consideration,  profit or loss to be  realized,  if any,  as a
                  result of an investment in the Shares; or

                       (iii)  That the past  performance  or  experience  of the
                  Company, or associates,  agents,  affiliates,  or employees of
                  the Company or any other  person,  will in any way indicate or
                  predict economic results in connection with the acquisition of
                  the Shares;

                  (m) The  information  set  forth in the  Investor  Suitability
         Questionnaire  prepared for  Subscriber's  acquisition  of the Assigned
         Units and executed by Subscriber is true,  correct and complete and may
         be relied on by the Company for purposes of  qualifying  Subscriber  to
         acquire the Shares;

                  (n) Subscriber has not  distributed  the Memorandum to anyone,
         no  other  person  has  used  the  Memorandum,  and  no  copies  of the
         Memorandum have been

                                        4
<PAGE>
         made by Subscriber; and

                  (o)  Subscriber  hereby agrees to indemnify  the Company,  and
         hold the  Company  harmless  from and  against  any and all  liability,
         damage, cost or expense incurred on account of or arising out of:

                       (i) Any inaccuracy in the declarations,  representations,

                  damages or redress from the Company; or (b) the disposition of
                  any of the Shares.

         demand of one or more Initiating  Holders,  requesting that the Company
         effect the  registration  under the Act of up to fifty percent (50%) of
         such  Initiating  Holder's  Registrable  Securities  and specifying the
         intended  method or methods of  disposition  thereof,  the Company will
         promptly, but in any event within ten (10) days, give written notice of
         such  demanded  registration  to  Subscriber,  or  its  successors  and
         assigns, as the case may be (the "Holder"),  and to the other acquirers
         of Registrable  Securities (together with the Holder, the "Holders") of

         effect the registration under the Act of:

                       (i) the Registrable Securities which the Company has been
                  so  demanded  to  register  by  such  Initiating  Holder,  for
                  disposition in accordance  with the intended method or methods
                  of disposition stated in such demand,

                       (ii) all other  Registrable  Securities which the Company
                  has been  demanded  to  register  by the  Holders  thereof  by
                  written  demand  delivered to the Company within ten (10) days
                  after  giving of such  written  notice by the  Company  (which
                  request  shall  specify  the  intended  method or  methods  of
                  disposition of such Registrable Securities), and

                       (iii) all shares of Common  Stock  which the  Company may
                  elect to register for its own account in  connection  with the
                  offering of  Registrable  Securities  pursuant to this Section
                  4.2,

                                        6
<PAGE>
         all to the extent  requisite to permit the  disposition  (in accordance
         with the intended  methods  thereof as  aforesaid)  of the  Registrable
         Securities so to be registered,  provided that the Company shall not be
         required  to effect  more than one (1)  registration  pursuant  to this
         Section  4.2.  If, at the date of  receipt  of a demand  by  Initiating
         Holder,  the  Company has  previously  filed a  registration  statement
         pursuant to the Act  (otherwise  than on Form S-4 or S-8 or any similar
         form for the registration of securities pursuant to an employee benefit
         plan or business combination or reorganization),  the Company may defer
         the filing of any such  demanded  registration  statement to a date not
         later  than  ninety  (90) days after the  effective  date of such prior
         registration statement.

                  (b) Registration  Statement Form. Each  registration  demanded
         pursuant  to this  Section  4.2 shall be  effected  by the  filing of a
         registration  statement  on any form which the  Company is  eligible to
         use, such form to be selected by the Company,  after  consultation with
         counsel and after notice of such selection of such form is delivered to
         the Holders of all  Registrable  Securities  electing to participate in
         such registration; provided, however, that if the Holders of at least a
         majority of the  Registrable  Securities as to which  registration  has
         been  demanded  pursuant  to this  Section  4.2 shall so  request,  the
         Company  shall  file  such  registration   statement  pursuant  to  the
         Commission's Rule 415, or any successor rule or regulation  thereto, so
         as to permit the  continuous  or delayed  offering  of the  Registrable
         Securities  in  accordance  with the  intended  method  of  disposition
         specified in the Initiating  Holder's notice pursuant to subsection (a)
         of this  Section  4.2, but in no event shall the Company be required to
         maintain  the  effectiveness  of such  registration  beyond  the period
         specified  in Section 4.4 (b).  Such  selection  of form by the Company
         shall be final  unless  the use of such  form has been  objected  to in
         writing by  Holders  holding  at least a  majority  of the  Registrable
         Securities as to which registration has been requested pursuant to this
         Section 4.2.

                  (c)  Expenses.  Except as otherwise  prohibited  by applicable
         law, the Company will pay all Registration  Expenses in connection with
         the registration of Registrable  Securities  requested pursuant to this
         Section 4.2.

                  (d) Effective Registration Statement. A registration requested
         pursuant to this Section 4.2 shall not be deemed to be effected  unless
         a registration  statement covering all shares of Registrable Securities
         specified in notices  received as described in subsection (a), for sale
         in  accordance  with  the  method  of  disposition   specified  by  the
         Initiating Holder, shall have been declared effective by the Commission
         or otherwise  becomes effective and, if such method of disposition is a
         firm commitment  underwritten  public  offering,  all such shares shall
         have been sold pursuant  thereto;  provided that a  registration  which
         does not become effective after the Company has substantially  prepared
         and has filed or is in a position to file a registration statement with
         respect  thereto  solely by reason of the  refusal to proceed of all of
         the  Initiating  Holders  (other than any refusal to proceed based upon
         the advice of their  counsel that the  registration  statement,  or the
         prospectus contained therein, contains an untrue

                                        7
<PAGE>
         statement of a material fact or omits to state a material fact required
         to be stated  therein or necessary to make the  statements  therein not
         misleading in light of the circumstances then existing) shall be deemed
         to have been effected by the Company at the request of such Holder.

         4.3.     Piggyback Registration Rights.

                  (a) Right to Include Registrable  Securities.  If, at any time
         within five (5) years from the date  hereof,  the  Company  proposes to
         register any of its equity securities under the Act, whether or not for
         sale for its own account,  on a form and in a manner which would permit
         registration of Registrable Securities for sale to the public under the
         Act, it will,  each such time,  give  notice at least  thirty (30) days
         prior  to the  proposed  filing  date  to all  Holders  of  Registrable
         Securities of its intention to do so,  describing  such  securities and
         specifying the form and manner and the other relevant facts involved in
         such proposed  registration  and, upon the written  request of any such
         Holder delivered to the Company within ten (10) business days after the
         giving of any such notice (which request shall specify the  Registrable
         Securities  intended to be disposed of by such Holder and the  intended
         method or methods of  disposition  thereof),  the Company shall use its
         best efforts to effect the  registration  under the Act of  Registrable
         Securities  which the  Company  has been  requested  to register by the
         Holders of Registrable Securities  (hereinafter  "Requesting Holders"),
         but not exceeding ten percent (10%) of the  Registrable  Securities and
         in the case of Subscriber and each such  subscriber in the Offering not
         exceeding ten percent (10%) of Subscriber's  Registrable  Securities to
         the extent  requisite to permit the disposition (in accordance with the
         intended methods thereof as aforesaid) of the Registrable Securities so
         to be registered,  of those Registrable Securities which the Company is
         requested  to  register  by  Holder  up to  ten  percent  (10%)  of the
         Registrable Securities provided that:

                       (i) if,  at any time  after  giving  such  notice  of its
                  intention to register any of its  securities  and prior to the
                  effective  date  of  the   registration   statement  filed  in
                  connection with such registration, the Company shall determine
                  for any reason not to register  such  securities,  the Company
                  may,   at  its   election,   give   written   notice  of  such
                  determination  to each Holder of  Registrable  Securities  and
                  thereupon  shall be relieved of its obligation to register any
                  Registrable  Securities in connection  with such  registration
                  (but not its  obligation to pay the  Registration  Expenses in
                  connection  therewith  as provided in  subsection  (b) of this
                  Section 4.3), without prejudice, however, to the rights of any
                  one or more  Holders  to  request  that such  registration  be
                  effected in a subsequent such registration;

                       (ii) if (a) the  registration  so proposed by the Company
                  involves an  underwritten  offering of the securities so being
                  registered  to  be  distributed  by or  through  one  or  more
                  underwriters of recognized  standing under  underwriting terms
                  appropriate for such a transaction, (b) the Company

                                        8
<PAGE>
                  proposes  that  the   securities  to  be  registered  in  such
                  underwritten  offering will not include all of the Registrable
                  Securities  requested to be so included,  and (C) the managing
                  underwriter  of such  underwritten  offering  shall advise the
                  Company in writing that, in its opinion,  the  distribution of
                  all or a  specified  portion  of such  Registrable  Securities
                  concurrently  with the  securities  being  distributed by such
                  underwriters   will   materially  and  adversely   affect  the
                  distribution  of such  securities by such  underwriters  (such
                  opinion to state the reasons therefor),  then the Company will
                  promptly  furnish each such Holder of  Registrable  Securities
                  with a copy of such opinion and may require, by written notice
                  to each  such  Holder  accompanying  such  opinion,  that  the
                  distribution of all or a specified portion of such Registrable
                  Securities be excluded from such  distribution  (in case of an
                  exclusion of a portion of such  Registrable  Securities,  such
                  portion to be allocated  among such Holders in  proportion  to
                  the respective numbers of shares of Registrable  Securities so
                  requested  to  be  registered  by  such  Holders);   provided,
                  however,  that no portion of the Registrable  Securities shall
                  be  excluded  if any  securities  are to be  included  in such
                  underwriting  for the  account  of any  person  other than the
                  Company;  and if the Company  shall  require such a reduction,
                  the Holder of Registrable  Securities  shall have the right to
                  withdraw from the offering;

                       (iii) the Company  shall not be  obligated  to effect any
                  registration of Registrable  Securities under this Section 4.3
                  incidental  to the  registration  of any of its  securities in
                  connection  with  mergers,   acquisitions,   exchange  offers,
                  dividend reinvestment plans or stock options or other employee
                  benefit  plans  or  incidental  to  the  registration  of  any
                  non-equity  securities not convertible into equity securities;
                  and,

                       (iv) the number of shares of Registrable Securities which
                  shall be included in each such  registration  shall not exceed
                  ten percent (10%) of the  Registrable  Securities  and, in the
                  case of Subscriber  and each such  subscriber in the Offering,
                  shall not exceed ten percent (10%) of Subscriber's Registrable
                  Securities.

                  No registration of Registrable  Securities effected under this
         Section  4.3 shall  relieve  the  Company of its  obligation  to effect
         registrations  of  Registrable   Securities  upon  the  request  of  an
         Initiating Holder pursuant to Section 4.2.

                  (b)  Expenses.  Except as otherwise  prohibited  by applicable
         law, the Company will pay all Registration  Expenses in connection with
         the registration of Registrable  Securities  requested pursuant to this
         Section 4.3.

         4.4      Registration  Procedures.  If  and  whenever  the  Company  is
         required  to use its best  efforts  to effect the  registration  of any
         Registrable  Securities  under the Act as  provided  in Section 4.2 and
         4.3, the Company shall promptly:

                                        9
<PAGE>
                  (a)  prepare  and (in any event  within  (90) days of the last
         date on which the  Holders  of  Registrable  Securities  may notify the
         Company of their  request to include  their  Registrable  Securities in
         such registration in accordance herewith or such earlier date as may be
         provided  elsewhere  herein) file with the  Commission  a  registration
         statement with respect to such Registrable  Securities and use its best
         efforts  to cause  such  registration  statement  to  become  effective
         provided  that,  in the  case  of a  registration  of  any  Registrable
         Securities  pursuant to Section 4.3, such preparation and filing may be
         delayed if, in the good faith  determination  of the Board of Directors
         of the  Company,  such  deferral  would be in the best  interest of the
         Company and such deferral  would be without  prejudice to the rights of
         the Holders of Registrable Securities to request that such registration
         be effected as a subsequent registration under Section 4.3;

                  (b) prepare and file with the Commission  such  amendments and
         supplements to such  registration  statement and the prospectus used in
         connection  therewith  as may be  necessary  to keep such  registration
         statement  effective and to comply with the  provisions of the Act with
         respect to the  disposition  of all  Registrable  Securities  and other
         securities covered by such registration  statement until the earlier of
         such time as all of such  Registrable  Securities and other  securities
         have been  disposed  of in  accordance  with the  intended  methods  of
         disposition  by the  seller  or  sellers  thereof  set  forth  in  such
         registration  statement or the  expiration  of one (1) year (or, in the
         case of registration of Registrable Securities pursuant to Section 4.3,
         ninety (90) days) after such registration  statement becomes effective;
         and will furnish, upon request, to each such seller and each Requesting
         Holder  prior  to the  filing  thereof  a  copy  of  any  amendment  or
         supplement to such  registration  statement or prospectus and shall not
         file any such  amendment  or  supplement  to which  any such  seller or
         Requesting  Holder shall have  reasonably  objected on the grounds that
         such  amendment or supplement  does not comply in all material  aspects
         with  the  requirements  of  the  Act or of the  rules  or  regulations
         thereunder;

                  (c) furnish to each seller of such Registrable  Securities and
         each  Requesting  Holder  such  number  of  conformed  copies  of  such
         registration  statement  and of  each  such  amendment  and  supplement
         thereto (in each case including all exhibits), such number of copies of
         the prospectus included in such registration  statement (including each
         preliminary prospectus and any summary prospectus),  in conformity with
         the  requirements of the Act, such documents,  if any,  incorporated by
         reference in such registration statement or prospectus,  and such other
         documents, as such seller or Requesting Holder may reasonably request;

                  (d)  use  its  best   efforts  to   register  or  qualify  all
         Registrable   Securities   and  other   securities   covered   by  such
         registration  statement under such other securities or blue sky laws of
         the  States  of the  United  States  as each  seller  shall  reasonably
         request,  to keep such  registration or  qualification in effect for so
         long as such registration  statement remains in effect,  and do any and
         all other acts and things which may be necessary or advisable to enable
         such seller to consummate the

                                       10
<PAGE>
         disposition in such jurisdictions of its Registrable Securities covered
         by such registration  statement,  except that the Company shall not for
         any such  purpose be required to qualify  generally to do business as a
         foreign  corporation  in any  jurisdiction  wherein it is not and would
         not, but for the  requirements  of this subsection (d), be obligated to
         be so  qualified,  or  to  subject  itself  to  taxation  in  any  such
         jurisdiction,  or to consent to general  service of process in any such
         jurisdiction;

                  (e)  upon  request,  furnish  to each  seller  of  Registrable
         Securities and each Requesting Holder a signed  counterpart,  addressed
         to such seller and such Requesting Holder, of (I) an opinion of counsel
         to the Company, dated the effective date of such registration statement
         (and, if such  registration  includes an underwritten  public offering,
         dated the date of the closing under the  underwriting  agreement),  and
         (ii) a "comfort" letter,  signed by the independent  public accountants
         who have certified the Company's financial  statements included in such
         registration  statement,   dated  after  the  effective  date  of  such
         registration statement (and, if such registration statement includes an
         underwritten  public offering,  dated the date of the closing under the
         underwriting  agreement),  covering substantially the same matters with
         respect to such  registration  statement (and the  prospectus  included
         therein) and, in the case of such accountants'  letter, with respect to
         events  subsequent  to the date of such  financial  statements,  as are
         customarily covered in opinions of issuer's counsel and in accountant's
         letters  delivered to underwriters in underwritten  public offerings of
         securities  and,  in the case of the  accountant's  letter,  such other
         financial  matters,  as the principal  underwriter  for such sellers or
         such Requesting Holders may reasonably request;

                  (f) immediately  notify each seller of Registrable  Securities
         covered by such registration  statement and each Requesting  Holder, at
         any time when a prospectus relating thereto is required to be delivered
         under the Act, upon discovery  that, or upon the happening of any event
         as a result of which,  the  prospectus  included  in such  registration
         statement,  as  then in  effect,  includes  an  untrue  statement  of a
         material fact or omits to state any material fact required to be stated
         therein or necessary to make the  statements  therein not misleading in
         light of the  circumstances  then existing,  which untrue  statement or
         omission   requires   amendment  of  the   registration   statement  or
         supplementation  of the  prospectus,  and at the  request  of any  such
         seller or  Requesting  Holder,  prepare  and furnish to such seller and
         Requesting  Holder a reasonable  number of copies of a supplement to or
         an  amendment  of such  prospectus  as may be  necessary  so  that,  as
         thereafter  delivered to the acquirers of such Registrable  Securities,
         such  prospectus  shall not include an untrue  statement  of a material
         fact or omit to state a material fact required to be stated  therein or
         necessary to make the statements therein not misleading in the light of
         the circumstances then existing;  provided, however that each Holder of
         Registrable   Securities   registered  pursuant  to  such  registration
         statement  agrees  that  such  Holder  will not  sell  any  Registrable
         Securities pursuant to such registration statement during the time that
         the Company is preparing and filing with the Commission a supplement to
         or an amendment of such prospectus or registration statement;

                                       11
<PAGE>
                  (g)  otherwise  use  its  best  efforts  to  comply  with  all
         applicable rules and regulations of the Commission,  and make available
         to  its  Holders,  as  soon  as  reasonably  practicable,  an  earnings
         statement  covering the period of at least twelve (12) months,  but not
         more than eighteen (18) months,  beginning  with the first month of the
         first fiscal  quarter  after the  effective  date of such  registration
         statement,  which  earnings  statement  shall satisfy the provisions of
         Section 11 (a) of the Act;

                  (h) provide and cause to be  maintained  a transfer  agent and
         registrar for all Registrable  Securities  covered by such registration
         statement  from and after a date not later than the  effective  date of
         such registration statement; and

                       (i)  use  its  best  efforts  to  list  all   Registrable
                  Securities  covered  by such  registration  statement  on each
                  securities  exchange  on which any of the Common  Stock of the
                  Company is then listed or, if the  Company's  Common  Stock is
                  not then quoted on NASDAQ or listed on any national securities
                  exchange,  use  its  best  efforts  to have  such  Registrable
                  Securities  covered by such  registration  statement quoted on
                  NASDAQ or, at the option of the Company,  listed on a national
                  securities exchange.

         The Company may require  each seller of  Registrable  Securities  as to
         which any  registration  is being  effected to furnish the Company such
         information   regarding  such  seller  and  the  distribution  of  such
         securities as the Company may from time to time  reasonably  request in
         writing  and as  shall  be  required  by law  or by the  Commission  in
         connection therewith and such seller shall furnish such information.

         4.5      Underwritten Offerings.

                  (a)  Underwritten  Offerings.  If  the  number  of  shares  of
         Registrable  Securities  and  any  other  securities  to be sold in any
         underwritten  offering involves a registration  requested by Initiating
         Holders  pursuant  to  Section  4.2  should  be  limited  due to market
         conditions or otherwise, the Company shall include in such registration
         to the extent of the number which the Company is so advised can be sold
         in such  offering  (I) first,  Registrable  Securities  requested to be
         included  in such  registration,  pro rata  among the  Holders  of such
         Registrable  Securities  on the  basis of the  number of shares of such
         securities  requested  to be included by such  Holders,  and (ii) other
         securities of the Company proposed to be included in such registration,
         in accordance  with the  priorities,  if any,  then existing  among the
         Company and the Holders of such securities.

                  (b) Underwriting  Agreement.  If requested by the underwriters
         for any underwritten offering of Registrable  Securities on behalf of a
         Holder or Holders of Registrable  Securities pursuant to a registration
         requested   under   Section   4.2,  the  Company  will  enter  into  an
         underwriting  agreement reasonably  acceptable to the Company with such
         underwriters  for  such  offering,   such  agreement  to  contain  such
         representations  and warranties by the Company and such other terms and
         provisions

                                       12
<PAGE>
         as are customarily contained in underwriting agreements with respect to
         distributions, including, without limitation, indemnities to the effect
         and to the extent provided in Section 4.7, provided, however, that such
         agreement shall not contain any provision  which is  inconsistent  with
         the provisions hereof.  The Holders of Registrable  Securities on whose
         behalf   Registrable   Securities   are  to  be   distributed  by  such
         underwriters  shall be parties to any such  underwriting  agreement and
         the  representations and warranties by, and the other agreements on the
         part of, the Company to and for the benefit of such underwriters  shall
         also be made to and for the  benefit  of such  Holders  of  Registrable
         Securities.  Such  Holders  of  Registrable  Securities  shall  not  be
         required by the Company to make any representations or warranties to or
         agreements with the Company or the  underwriters  other than reasonable
         representations,   warranties   or  agreements   (including   indemnity
         agreements  customary in secondary  offerings)  regarding  such Holder,
         such Holder's Registrable  Securities and such Holder's intended method
         or methods of disposition and any other representation required by law.

                  (c) Piggyback  Underwritten  Offerings.  If the Company at any
         time  proposes  to  register  any of its  securities  under  the Act as
         contemplated  by Section 4.3 and such  securities are to be distributed
         by or through one or more  underwriters,  the Company will use its best
         efforts,  if requested  by any Holder of  Registrable  Securities,  who
         requests piggyback registration of Registrable Securities in connection
         therewith  pursuant to Section 4.3 to arrange for such  underwriters to
         include  the  Registrable  Securities  to be  offered  and sold by such
         Holder  among the  securities  to be  distributed  by or  through  such
         underwriters,  provided  that,  for  purposes of this  sentence,  "best
         efforts"  shall not  require  the  Company to reduce the amount or sale
         price of such securities  proposed to be distributed by or through such
         underwriters.  The Holders of Registrable  Securities to be distributed
         by such  underwriters  shall be parties to the  underwriting  agreement
         between the Company and such underwriters and the  representations  and
         warranties by, and the other  agreements on the part of, the Company to
         and for the benefit of such underwriters, shall also be made to and for
         the benefit of such Holders of Registrable Securities,  and the Company
         will cooperate  with such Holders of Registrable  Securities to the end
         that the  conditions  precedent to the  obligations  of such Holders of
         Registrable  Securities  under such  underwriting  agreement  shall not
         include  conditions that are not customary in  underwriting  agreements
         with respect to combined primary and secondary  distributions and shall
         be otherwise  satisfactory to such Holders. Such Holders of Registrable
         Securities shall not be required by the Company to make representations
         or  warranties  to  or  agreements   (including   customary   indemnity
         agreements) with the Company or the underwriters  other than reasonable
         representations,  warranties or agreements  regarding such Holder, such
         Holder's  Registrable  Securities and such Holder's  intended method or
         methods of distribution and any other representation required by law.

                  (d)  Selection  of   Underwriters.   Whenever  a  registration
         requested pursuant to Section 4.2 is for an underwritten  offering, the
         Holders of a majority of

                                       13
<PAGE>
         the Registrable Securities included in such registration shall have the
         right to select the managing underwriter(s) to administer the offering,
         subject to the approval of the  Company,  which  approval  shall not be
         unreasonably  withheld. If the Company at any time proposed to register
         any of its  securities  under the Act for sale for its own  account and
         such  securities  are to be  distributed  by or  through  one  or  more
         underwriters,  the  selection of the managing  underwriter(s)  shall be
         made by the Company and notice of the  selection  thereof  delivered to
         the Holders of all  Registrable  Securities  eligible to participate in
         such registration.

                  (e)  Holdback  Agreements.  If any  registration  pursuant  to
         Section 4.2 or 4.3 shall be in connection with an  underwritten  public
         offering,  each Holder of Registrable  Securities agrees by acquisition
         of  such  Registrable  Securities,  if  so  required  by  the  managing
         underwriter,   not  to  effect  any  public  sale  or  distribution  of
         Registrable  Securities (other than as part of such underwritten public
         offering)  within  seven (7) days prior to the  effective  date of such
         registration  statement  or one  hundred  twenty  (120)  days after the
         effective date of such registration statement.

         4.6      Preparation:  Reasonable Investigation. In connection with the
         preparation  and  filing  of each  registration  statement  registering
         Registrable Securities under the Act, the Company will give the Holders
         of Registrable  Securities on whose behalf such Registrable  Securities
         are to be so registered and the  Underwriters,  if any, each Requesting
         Holder, and their respective  counsel and accountants,  the opportunity
         to participate in the preparation of such registration statement,  each
         prospectus  included  therein  or filed  with the  Commission  and each
         amendment  thereof or  supplement  thereto,  and will give each of them
         such access to its books and records and such  opportunities to discuss
         the  business  of the Company  with its  officers  and the  independent
         public accountants who have certified its financial statements as shall
         be reasonably  necessary to conduct a reasonable  investigation  within
         the  meaning of the Act.  To  minimize  disruption  and  expense to the
         Company  during  the  course of the  registration  process,  sellers of
         Registrable Securities to be covered by any such registration statement
         shall  coordinate  their   investigation   and  due  diligence  efforts
         hereunder and, to the extent practicable, will act through a single set
         of counsel and a single set of accountants.

         4.7      Indemnification.

                  (a)  Indemnification  by  the  Company.  In the  event  of any
         registration  of any  securities  of the  Company  under  the Act,  the
         Company shall,  and hereby does,  hereby indemnify and hold harmless in
         the case of any  registration  statement filed pursuant to this Section
         4.2 or 4.3, the seller of any  Registrable  Securities  covered by such
         registration statement, such seller's directors, trustees and officers,
         each other person who participates as an underwriter in the offering or
         sale of such  securities  and each other  person,  if any, who controls
         such  seller or any such  underwriter  within  the  meaning  of the Act
         against any losses, claims, damages,  liabilities or expenses, joint or
         several, to which such seller or Requesting Holder or any such director
         or officer or  participating  person or  controlling  person may become
         subject  under the Act or  otherwise,  insofar as such losses,  claims,
         damages,  liabilities or expenses (or actions or proceedings in respect
         thereof)  arise out of or are based  upon (x) any untrue  statement  or
         alleged  untrue  statement  of  any  material  fact  contained  in  any
         registration  statement  under which such  securities  were  registered
         under the Act, any preliminary prospectus,  final prospectus or summary
         prospectus  contained therein,  or any amendment or supplement thereto,
         or any document  incorporated by reference therein, or (y) any omission
         or alleged  omission to state  therein a material  fact  required to be
         stated  therein  or  necessary  to  make  the  statements  therein  not
         misleading,  and the Company will  reimburse  such  seller,  Requesting
         Holder and each such director,  trustee, officer,  participating person
         and controlling  person for any legal or any other expenses  reasonably
         incurred by them in connection with investigating or defending any such
         loss, claim, liability, action or proceeding, provided that the Company
         shall not be liable in any such case to the extent  that any such loss,
         claim, damage, liability or expense (or action or proceeding in respect
         thereof) arises out of or is based upon an untrue  statement or alleged
         untrue   statement  or  omission  or  alleged  omission  made  in  such
         registration  statement,   any  such  preliminary   prospectus,   final
         prospectus,  summary  prospectus,  amendment or  supplement in reliance
         upon and in  conformity  with  information  furnished to the Company by
         such seller or such  Requesting  Holder or any such director,  trustee,
         officer, participating person or controlling person.

                  (b) Indemnification by the Seller. The Company may require, as
         a condition to including  Registrable  Securities  in any  registration
         statement  filed pursuant to Section 4.2 or 4.3, that the Company shall
         have received an undertaking  satisfactory to it from each  prospective
         seller of such securities,  severally and not jointly, to indemnify and
         hold  harmless  (in the same manner and to the same extent as set forth
         in  subsection  (a) of this Section 4.7) the Company,  each director of
         the  Company,   each  officer  of  the  Company  who  shall  sign  such
         registration  statement and each other person, if any, who controls the
         Company  within  the  meaning  of the Act,  with  respect to any untrue
         statement  in  or  omission  from  such  registration  statement,   any
         preliminary prospectus, final prospectus or summary prospectus included
         therein,  or any amendment or supplement  thereto, if such statement or
         omission was made in reliance upon and in conformity  with  information
         furnished

                                       15
<PAGE>
         to the Company by such  seller.  Such  indemnity  shall  remain in full
         force and effect regardless of any  investigation  made by or on behalf
         of the Company or any such director,  officer or controlling person and
         shall survive the transfer of such securities by such seller.

                  (c)  Notice of  Claims,  etc.  Promptly  after  receipt  by an
         indemnified  party of notice of the  commencement  of any action or any
         proceeding involving a claim referred to in the preceding subsection of
         this Section 4.7,  such  indemnified  party will, if a claim in respect
         thereof  is to be made  against an  indemnifying  party,  give  written
         notice to the latter of the commencement of such action,  provided that
         the failure of any indemnified party to give notice as provided therein
         shall not relieve the indemnifying  party of its obligations  under the
         preceding  subsections  of this Section 4.7,  except to the extent that
         the  indemnifying  party  is  actually  materially  prejudiced  by such
         failure  to give  notice.  In case such  action is  brought  against an
         indemnified  party,  unless  in  such  indemnified  party's  reasonable
         judgment  (I) a conflict  of  interest  between  such  indemnified  and
         indemnifying  parties may exist in respect of such  claim,  or (ii) the
         indemnified  party has  available to it reasonable  defenses  which are
         different  from or  additional to those  available to the  indemnifying
         party, the  indemnifying  party shall be entitled to participate in and
         to assume the  defense  thereof,  jointly  with any other  indemnifying
         party similarly notified,  to the extent that it may wish, with counsel
         reasonably  satisfactory to such  indemnified  party,  and after notice
         from the indemnifying  party to such indemnified  party of its election
         so to assume the defense thereof,  the indemnifying  party shall not be
         liable  to such  indemnified  party  for any  legal or  other  expenses
         subsequently  incurred  by the latter in  connection  with the  defense
         thereof other than reasonable costs of  investigation.  Notwithstanding
         the foregoing, in any such action, any indemnified party shall have the
         right to retain its own counsel but the fees and  disbursements of such
         counsel  shall be at the expense of such  indemnified  party unless (I)
         the  indemnifying  party  shall have  failed to retain  counsel for the
         indemnified  person as aforesaid,  or (ii) the  indemnifying  party and
         such  indemnified  party shall have mutually agreed to the retention of
         such counsel.  It is understood that the indemnifying  party shall not,
         in  connection   with  any  action  or  related  actions  in  the  same
         jurisdiction, be liable for the fees and disbursements of more than one
         separate firm qualified in such  jurisdiction to act as counsel for the
         indemnified  party. The indemnifying  party shall not be liable for any
         settlement of any proceeding  effected  without its written consent but
         if settled  with such  consent or if there be a final  judgment for the
         plaintiff,  the indemnifying  party agrees to indemnify the indemnified
         party  from  and  against  any  loss or  liability  by  reason  of such
         settlement  or  judgment.  No  indemnifying  party  shall,  without the
         consent of the indemnified  party,  consent to entry of any judgment or
         enter into any  settlement  which does not include as an  unconditional
         term   thereof  the  giving  by  the  claimant  or  plaintiff  to  such
         indemnified  party of a release  from all  liability in respect to such
         claim or litigation.

                  (d) Other  Indemnification.  Indemnification  similar  to that
         specified in the

                                       16
<PAGE>
         preceding   subsections   of  this   Section   4.7  (with   appropriate
         modifications)  shall be  given  by the  Company  and  each  seller  of
         Registrable  Securities  with respect to any required  registration  or
         other qualification of such Registrable Securities under any federal or
         state law or regulation of governmental authority other than the Act.

                  (e) Contribution.  If the indemnification provided for in this
         Section  4.7  is  unavailable  or  insufficient  to  hold  harmless  an
         indemnified   party  in  respect  of  any  losses,   claims,   damages,
         liabilities  or  expenses   described  as  indemnifiable   pursuant  to
         subsections (a) or (b), then each indemnifying  party shall, in lieu of
         indemnifying such indemnified  party,  contribute to the amount paid or
         payable by such indemnified party, as a result of such losses,  claims,
         damages,  liabilities or expenses in such  proportion as appropriate to
         reflect the  relative  fault of the Company,  on the one hand,  or such
         seller of Registrable Securities on the other hand, and to the parties'
         relative  intent,  knowledge,  access to information and opportunity to
         correct or prevent any untrue statement or omission giving rise to such
         indemnification  obligation.  The Company and the Holder of Registrable
         Securities   agree  that  it  would  not  be  just  and   equitable  if
         contributions  pursuant to this  subsection (e) were  determined by pro
         raga allocation (even if Holders of Registrable Securities were treated
         as one entity for such  purpose) or by any other  method of  allocation
         which did not take account of the equitable  considerations referred to
         above  in  this   subsection   (e).  No  person  guilty  of  fraudulent
         misrepresentations  (within  the  meaning of Section 11 (f) of the Act)
         shall be entitled to contribution  from any person who is not guilty of
         such fraudulent misrepresentation.

                  (f) Indemnification  Payments. The indemnification required by
         this  Section  4.7 shall be made by  periodic  payments  of the  amount
         thereof during the course of the investigation or defense,  as and when
         bills  are  received  or any  expense,  loss,  damage or  liability  is
         incurred.

                  (g)  Limitation  on  Seller's  Payments.  Notwithstanding  any
         provision  hereof  to the  contrary,  the  liability  of any  seller of
         Registrable  Securities under this Section 4.2 shall in no event exceed
         the  proceeds  received  by such  seller  from the sale of  Registrable
         Securities  covered by the  registration  statement giving rise to such
         liability.

         5.       Nominees for Beneficial  Owners.  In the event any Registrable
         Securities are held by a nominee for the beneficial owner thereof,  the
         beneficial owner thereof may, at its election, be treated as the Holder
         of such  Registrable  Securities  for  purposes of any request or other
         action by any Holder or Holders of Registrable  Securities  pursuant to
         this  Agreement or any  determination  of any number or  percentage  of
         shares of  Registrable  Securities  held by any  Holder or  Holders  of
         Registrable   Securities   contemplated  by  this  Agreement.   If  the
         beneficial owner of any Registrable  Securities so elects,  the Company
         may require  assurances  reasonably  satisfactory to it of such owner's
         beneficial ownership of such Registrable Securities.

         Agreement  shall survive upon the death or disability of Subscriber and

                           FOR DIRECTORS AND OFFICERS


         This Lock-Up  Agreement  ("Agreement")  is effective as of September 1,
1996 by and among M.D.  Labs,  Inc.,  a Delaware  corporation  (the  "Company"),
_______________  , a director  and/or officer of the Company (the  "Executive"),

security or other instrument which by its terms is convertible into, exercisable
for, or  exchangeable  for shares of the Company's  common stock for a period of
six (6) months from the effective date of the Registration  Statement;  provided
that the foregoing  shall not prohibit the Executive from exercising any warrant
or option to purchase shares of the Company's common stock.

         2.  Successors.  The  provisions of this  Agreement  shall be deemed to
obligate,  extend  to and  inure  to the  benefit  of the  successors,  assigns,
transferees, grantees and indemnitees of each of the parties to this Agreement.

         3.  Attorneys  Fees.  In the event of a  dispute  between  the  parties
concerning the enforcement or interpretation  of this Agreement,  the prevailing
party in such  dispute,  whether by legal  proceedings  or  otherwise,  shall be
reimbursed  immediately  for the reasonably  incurred  attorneys' fees and other
costs and expenses by the other parties to the dispute.

         4. Choice of Law. This Agreement  shall be governed by and construed in
accordance  with the laws of the State of  California  without  reference to its
choice of law rules.

         5.  Arbitration.  Any dispute or claim arising to or in any way related
to this Agreement shall be settled by arbitration in San Diego, California.  All
arbitration  shall be conducted in accordance  with the rules and regulations of
the American Arbitration  Association ("AAA"). AAA shall designate an arbitrator
from an approved list of arbitrators following both parties' review and deletion
of those  arbitrators  on the approved  list having a conflict of interest  with
either  party.  Each  party  shall  pay its own  expenses  associated  with such
arbitration  (except as set forth in Section 3 above).  A demand for arbitration
shall be made within a reasonable time after the claim,  dispute or other matter
has  arisen  and in no event  shall  such  demand  be made  after  the date when
institution of legal or equitable  proceedings  based on such claim,  dispute or
other  matter  in  question  would  be  barred  by the  applicable  statutes  of
limitations. The decision of the arbitrators shall be rendered within 60 days of
submission  of any claim or  dispute,  shall be in writing and mailed to all the
parties

         6.  Counterparts.  This  Agreement  may be  executed  in  one  or  more
counterparts, each of which shall be deemed an original, but all of which, taken
together, shall constitute one and the same instrument.

royalty fee of $.09(nine  cents) for each unit (box) of "Women's  Nature Natural
Balance Herbal Tea" sold for 18 months beginning on the date that the first unit
(box) of  "Women's  Nature  Natural  Balance  Herbal  Tea" is  sold,  and at the
conclusion of said 18 months Houston will pay Dr. Kimata a royalty of $.05 (five
cents) for each unit (box) of "Women's  Nature Natural  Balance Herbal Tea" sold
thereafter.  Houston  will provide  said  royalty  payments to Dr.  Kimata on or
before  the last day of each  calendar  month for all sales of  "Women's  Nature

Natural Balance Herbal Tea" sold unless either party to this agreement shall, at
least 180 days prior to the  expiration  of any term,  advise the other party in
writing  that it does not intend to renew the  agreement.  Should  either  party
choose to not renew the agreement and notify the other party in accordance  with
this agreement, Houston will continue to sell and market "Women's Nature Natural
Balance  Herbal Tea" and pay Dr. Kimata the defined  royalty on said sales until

forfeit  the  right to use any  reference  to Dr.  Kimata  in  association  with
"Women's  Nature  Natural  Balance  Herbal Tea" and Dr.  Kimata will forfeit the
right to any royalty payments for any sales occurring after the termination date
of this agreement and the exhaustion of all inventory in stock and/or on order.

not disclose or make known to any person or party any of Houston's trade secrets
or processes or any part thereof which she may learn or be exposed to during the

Dr. Kimata will be paid as an independent  consultant to Houston and will not be
considered  an  employee  of  Houston.  It is  understood  that  this  agreement
supercedes any and all prior agreements,  oral or written,  made between Houston

                                    RECITALS

conditions set forth below.

                                   AGREEMENTS

         Agreement.

                  2.       Term.  This  engagement  of Consultant by the Company
         shall  commence on October 7, 1996, and continue until October 6, 1997.

<PAGE>
                  by the Chief  Executive  Officer or Board of  Directors of the
                  Company from time to time;

                           b.       Perform such other duties as may be assigned
                  by the Chief  Executive  Officer or Board of  Directors of the
                  Company from time to time.

                  Consultant agrees to serve the Company faithfully, diligently,
         and to the  best  of  his  ability  and to  devote  his  working  time,
         attention,  and energies to the Company's  business as required for the
         efficient and timely  performance  of  Consultant's  duties  hereunder.
         Consultant  shall act in the best interests of the Company at all times
         in performing his duties and responsibilities hereunder.

                  4.       Compensation.  Consultant shall receive as his entire
         compensation  from the Company for his services  hereunder a warrant to
         purchase  100,000  shares of the  Company's  common  stock at $7.00 per
         share, identical in substance to Exhibit "A" attached hereto.

                  5.       Expense  Reimbursement.  The  Company  shall  pay all
         ordinary and  reasonable  expenses of  Consultant,  up to $1,500.00 per
         month,  incurred in  connection  with the  rendering of services to the
         Company as a consultant pursuant to this Agreement,  upon submission of
         appropriate  vouchers and supporting  documentation  in accordance with
         the Company's usual and ordinary practices, provided that such expenses
         are  reasonable  and necessary  business  expenses of the Company,  and
         provided   further   that  all  items  for  which  at  least   $250  in
         reimbursement is requested must be approved in advance,  in writing, by
         the Company.

                  6.       Return   of  the   Company's   Materials.   Upon  the
         termination of this Agreement,  Consultant shall promptly return to the
         Company all files,  credit cards,  keys,  instruments,  equipment,  and
         other materials, if any, owned or provided by the Company.

                  7.       Terms of Consulting  Arrangement.  Consultant will be
         the sole  judge  of the  means,  manner,  and  method  by which he will
         perform the services  contracted for, the times at which those services
         will be performed (within the deadlines  reasonably  established by the
         Company) and the sequence of performance of those services.  Consultant
         warrants that he will perform the services for which he has  contracted
         in a timely and workmanlike  manner.  Consultant  acknowledges that for
         the  term of  this  Agreement,  Consultant  is not an  employee  of the
         Company and that he will not be treated or  regarded  as the  Company's
         employee   under  the  laws  or   regulations   of  any  government  or
         governmental  agency.  This  Agreement  does not constitute a hiring by
         either party.  The  Consultant and the Company will be and shall remain
         independent  contractors  bound by the  provisions  of this  Agreement.
         Consultant is under the control of the Company only as to the result of
         Consultant's work and not as to the means,
                                      - 2 -
<PAGE>
         manner, and methods by which such result is accomplished. Neither party
         hereto shall be liable for any obligation  incurred by the other except
         as  provided  in  Section 5 of this  Agreement.  The Company  shall not
         withhold from  Consultant's  fees any amounts for income taxes or other
         similar assessments. The Company shall provide the use of its employees
         as deemed suitable by the Company to assist  Consultant in carrying out
         his duties hereunder.

                  8.       Non-Competition. Consultant will not, during the term
         of this  Agreement,  directly  or  indirectly  manage,  operate,  join,
         control, or participate or become interested in or be connected with as
         an employee,  partner, officer, director,  stockholder,  consultant, or
         investor, any corporation,  partnership, or other business entity other
         than the Company or its  affiliates,  which shall operate a business in
         competition  with  the  business   conducted  by  the  Company  or  its
         affiliates.  Nothing  herein  shall  prohibit  Consultant  from owning,
         solely  for  investment  purposes,  publicly-traded  securities  of any
         company which operates a business otherwise  covered by this Section 8,
         provided that such ownership constitutes less than 1% of the issued and
         outstanding  equity  or debt  securities,  as the case may be,  of such
         company.

                  9.       Confidential  Treatment  of  Information.  Consultant
         shall not, either during or after the term of this Agreement,  directly
         or indirectly  publish or disclose to any third party any  confidential
         information  pertaining  to the  business  of the  Company  unless  the
         Company gives written  authorization to do so. Such  information  shall
         not be used apart from Company business without the written approval of
         the  Company.  Such  prohibition  against  disclosure  applies  to  all
         confidential  information,  such as  non-public  information  about the
         Company's finances,  any trade secrets, and any other information which
         is normally kept confidential by the Company.

                  10.      Remedies. The parties further agree that the services
         to be performed hereunder are of a unique,  special,  and extraordinary
         character and that any breach or threatened breach by Consultant of any
         provision  of Section 8 or 9 of this  Agreement shall cause the Company
         irreparable harm which cannot be remedied solely by damages. Therefore,
         in the event of any  controversy  concerning  the rights or obligations
         under this Agreement,  such rights or obligations  shall be enforceable
         in a  court  of  competent  jurisdiction  at  law  or in  equity  by an
         injunction  or a decree of  specific  performance  or,  if the  Company
         elects,  by  obtaining  damages or such other relief as the Company may
         elect to  pursue.  Such  remedies,  however,  shall be  cumulative  and
         nonexclusive  and shall be in addition to any other  remedies which the
         Company may have.

                  11.      Indemnity.  The  Company  shall not be liable for and
         Consultant shall indemnify,  defend, and hold the Company harmless from
         any liability,  claim, or loss whatsoever for any injury to or death of
         Consultant, or for any damages to Consultant's property or the property
         of any of its representatives or agents unless and only to the
                                      - 3 -
<PAGE>
         extent that such loss or damage is directly caused by the negligence of
         the Company or its employees.  Consultant shall also indemnify, defend,
         and hold  the  Company  harmless  from any  liability,  claim,  or loss
         whatsoever for any personal injury or death and for any property damage
         resulting  from the conduct or negligent  omission of Consultant or his
         representatives or agents.

                  12.      Taxes.  Consultant shall be responsible for reporting
         and paying any and all taxes imposed by any government or  governmental
         entity  whatsoever  in  connection  with  the  payments  to  Consultant
         contemplated  by this  Agreement,  and  shall  indemnify  and  hold the
         Company harmless with respect thereto.

                  13.      Assignment. This Agreement and the respective rights,
         duties, and obligations of Consultant hereunder may not be assigned and
         may not be delegated by Consultant,  but the respective rights, duties,
         and  obligations of the Company  hereunder may be assigned or delegated
         by the Company to a parent or affiliated corporation or entity.

                  14.      Notice.  All  notices,  demands,   instructions,   or
         requests  relating to this Agreement shall be in writing and, except as
         otherwise  provided herein,  shall be deemed to have been given for all

         Agreement are  severable,  it being the intention of the parties hereto
         that should any  provisions  hereof be invalid or  unenforceable,  such

         and effect as if such invalid or unenforceable provisions were omitted.

                  18.      Applicable  Law. This Agreement  shall be governed by

         deemed an original but all of which together  shall  constitute one and
         the same agreement.

                             STOCK PURCHASE WARRANT

                      WARRANT TO PURCHASE 100,000 SHARES OF
                        COMMON STOCK AS DESCRIBED HEREIN


Dated: September 13, 1996

                    This certifies that, for value received:

             Name:             Kenneth A. Steel, Jr.

             Address:          1336 State Parkway
                               Chicago, Illinois 60610

is  entitled to purchase  from M.D.  Labs,  Inc.,  a Delaware  corporation  (the
"Company"),  having its principal  office at 1719 W.  University Dr., Suite 187,
Tempe,   Arizona  85281,   One  Hundred   Thousand   (100,000)  fully  paid  and
nonassessable  shares of Common  Stock,  par value  $.001,  of the Company  (the
"Common Stock"),  subject to the terms set forth herein, at an exercise price of
$7.00 per  share,  subject to  adjustment  as  provided  elsewhere  herein  (the
"Warrant Price").  The holder of this Warrant shall be referred to herein as the
"Warrantholder" or the "Holder." This Warrant is issued pursuant to a consulting
agreement  dated September 13, 1996 by and between the Company and the Holder as
consideration for Holder's  commitment to provide  consultation  services to the
Company.

         1.       "Common  Stock." If at any time,  as a result of an adjustment
made pursuant to Section 4, the securities  or other  property  obtainable  upon
exercise of this Warrant shall include shares or other securities of the Company
other than common stock or securities of another  corporation or other property,
thereafter  the number of such other shares or other  securities  or property so
obtainable  shall be subject to adjustment  from time to time in a manner and on
terms as nearly  equivalent as practicable to the provisions with respect to the
Common  Stock  contained in Section 4, and all other  provisions of this Warrant
with  respect to the Common  Stock  shall  apply on like terms to any such other
shares or other securities or property. Subject to the foregoing, and unless the
context requires otherwise, all references herein to "Common Stock"
<PAGE>
shall,  in the event of an adjustment  pursuant to Section 4, be deemed to refer
as well to any other  securities or property then obtainable as a result of such
adjustments.

         2.       Exercise of Warrant.  The purchase rights  represented by this
Warrant may be exercised by the Warrantholder or its duly authorized attorney or
representative,  in whole or in part (but not as to a fractional share of Common
Stock),  at any time and from time to time during the period  commencing  on the
date  described  in the Vesting  Schedule  below (the  "Commencement  Date") and
expiring at 5:00 p.m.,  Mountain  Standard Time, August 1, 2001 (the "Expiration
Date")(or such earlier date as may be provided pursuant to Section 9 herein), or
if such date is a day on which federal or state chartered  banking  institutions
are authorized by law to close,  then on the next succeeding day which shall not
be such a day, upon  presentation of this Warrant at the principal office of the
Company, or at the office of its stock transfer agent, if any, with the purchase
form attached hereto duly completed and signed,  and upon payment to the Company
in cash or by certified  check or bank draft of an amount equal to the number of
shares being so purchased  multiplied  by the Warrant  Price,  together with all
taxes applicable upon such exercise.  The Company agrees that the  Warrantholder
will be deemed the record  owner of such  shares as of the close of  business on
the date on which the Warrant  shall have been  presented and payment shall have
been made for such shares as  aforesaid.  Certificates  for the shares of Common
Stock so purchased shall be delivered to the  Warrantholder  within a reasonable
time,  not  exceeding  20  days,  after  the  exercise  in  full  of the  rights
represented by this Warrant.

         If the  Warrant is  exercised  in part only,  the Company  shall,  upon
surrender of this Warrant for cancellation, deliver a new Warrant evidencing the
rights of the  Warrantholder  to  purchase  the  balance of the shares of Common
Stock which the Warrantholder is entitled to purchase hereunder.

         3.       Vesting  Schedule.  Subject to Section 9 herein,  the purchase
rights  represented by this Warrant shall become exercisable on a pro-rata daily
basis over the course of one year,  based on a 365-day year (i.e.  approximately
273.972 shares per day),  beginning  August 1, 1996,  and  continuing  until the
earlier of July 31, 1997 or the  termination of the  Warrantholder's  consulting
agreement with the Company.

         4.       Certain Adjustments to Warrant.

                  (a)      In case  the  Company  shall  (i) pay a  dividend  in
shares of Common Stock or make a  distribution  in shares of Common Stock,  (ii)
subdivide its outstanding  shares of Common Stock, (iii) combine its outstanding
shares of Common  Stock into a smaller  number of shares of Common Stock or (iv)
issue by  reclassification of its shares of Common Stock other securities of the
Company,  the number of shares of Common Stock purchasable upon exercise of this
Warrant  immediately  prior thereto shall be adjusted so that the  Warrantholder
shall be entitled  to receive  the kind and number of shares of Common  Stock or
other  securities of the Company which he would have owned or have been entitled
to  receive at the  happening  of any of the events  described  above,  had such
Warrant been exercised immediately prior to the
                                        2
<PAGE>
happening of such event or any record date with respect  thereto.  An adjustment
made pursuant to this paragraph (a) shall become effective immediately after the
effective  date of such event  retroactive  to the record date, if any, for such
event.

                  (b)      Whenever   the  number  of  shares  of  Common  Stock
purchasable  upon the exercise of this Warrant is adjusted,  as herein provided,
the  Warrant  Price  shall  be  adjusted  by  multiplying   such  Warrant  Price
immediately prior to such adjustment by a fraction, of which the numerator shall
be the number of shares of Common  Stock  purchasable  upon the exercise of this
Warrant immediately prior to such adjustment, and of which the denominator shall
be the number of shares of Common Stock so purchasable immediately thereafter.

                  (c)      In the  event  of any  adjustment  pursuant  to  this
Section 4, no  fractional shares of Common  Stock shall be issued in  connection
with the  exercise  of any  Warrants,  but the  Company  shall,  in lieu of such
fractional  shares,  make such cash payment therefor on the basis of the current
market price on the day immediately prior to exercise.

                  (d)      Irrespective  of any  adjustments  pursuant  to  this
Section  to the  Warrant  Price or to the  number of shares or other  securities
obtainable upon exercise of this Warrant, this Warrant may continue to state the
Warrant Price and the number of shares  obtainable  upon  exercise,  as the same
price and number of shares stated herein.

         5.       Merger; Change in Control.

                  (a)      Change in Control shall be deemed to have occurred if
(i) any  "person"  (as such  term is used in  Paragraphs  13(d) and 14(d) of the
Securities Exchange Act of 1934, as amended [the "Exchange Act"]),  other than a
trustee or other fiduciary holding  securities under an employee benefit plan of
the Company or a corporation owned directly or indirectly by the stockholders of
the Company in substantially the same proportions as their ownership of stock of
the  Company,  is or becomes  the  "beneficial  owner" (as defined in Rule 13d-3
under  said  Act),  directly  or  indirectly,   of  securities  of  the  Company
representing  one-third  or more of the total voting  power  represented  by the
Company's  then  outstanding  Common  Stock,  or (ii)  during  any period of two
consecutive  years,  individuals who at the beginning of such period  constitute
the Board of Directors of the Company and any new director whose election by the
Board of Directors or nomination for election by the Company's  stockholders was
approved by a vote of at least  two-thirds  (2/3) of the directors then still in
office  who  either  were  directors  at the  beginning  of the  period or whose
election or nomination  for election was  previously so approved,  cease for any
reason to  constitute  a  majority  thereof,  or (iii) the  stockholders  of the
Company  approve  a merger  or  consolidation  of the  Company  with  any  other
corporation,  other than a merger or  consolidation  which  would  result in the
Common Stock of the Company outstanding  immediately prior thereto continuing to
represent  (either by remaining  outstanding  or by being  converted into Common
Stock of the  surviving  entity) at least  two-thirds  of the total voting power
represented  by the  Common  Stock  of the  Company  or  such  surviving  entity
outstanding immediately after such merger or consolidation,  or the stockholders
of the  Company  approve a plan of  complete  liquidation  of the  Company or an
agreement for the sale or
                                        3
<PAGE>
disposition by the Company of (in one  transaction or a series of  transactions)
all or substantially all the Company's assets.

                  (b)      In  the   event  of  a   merger,   consolidation   or
reorganization  with  another  corporation  in  which  the  Company  is not  the
surviving corporation, the Company (subject to the approval of the Board) or the
board of directors of any  corporation  assuming the  obligations of the Company
hereunder shall take action pursuant to either clause (i) or (ii) below:

                           (i)      Appropriate  provision  may be made  for the
protection  of  this  Warrant  by the  substitution  on an  equitable  basis  of
appropriate shares of the surviving corporation, provided that the excess of the
aggregate fair market value (as determined by the Company) of the shares subject
to this Warrant  immediately  before such  substitution  over the exercise price
hereof is not more than the excess of the  aggregate  fair  market  value of the
substituted shares made subject to purchase  immediately after such substitution
over the exercise price thereof; or

                           (ii)     Appropriate  provision  may be made  for the
cancellation  of this Warrant.  In such event,  the Company,  or the corporation
assuming  the  obligations  of the  Company  hereunder,  shall pay the Holder an
amount  of cash  (less  normal  withholding  taxes)  equal to the  excess of the
highest fair market value per share of the Common Stock during the 60-day period
immediately  preceding  the merger,  consolidation  or  reorganization  over the
exercise  price,  multiplied  by the number of shares  subject  to this  Warrant
(whether or not then exercisable).

                  (c)      Upon a  Change  in  Control,  subject  to  Section  9
herein,  this Warrant  (provided that it has been  outstanding  for at least six
months) shall  accelerate so that the Holder shall have the right,  at all times
until the  expiration or earlier  termination  of this Warrant,  to exercise the
unexercised  portions of this  Warrant,  including  the portions  thereof  which
would, but for this paragraph 5(c), not yet be exercisable.

         6.       Covenants of the  Company.  The Company  covenants  and agrees
that:

                  (a)      During the period within which the rights represented
by the Warrant may be exercised,  the Company will at all times reserve and keep
available,  free from  preemptive  rights out of the aggregate of its authorized
but  unissued  Common  Stock,  for the  purpose of  enabling  it to satisfy  any
obligation  to issue shares of Common  Stock upon the exercise of this  Warrant,
the  number of shares of Common  Stock  deliverable  upon the  exercise  of this
Warrant.  If at any time the number of shares of  authorized  Common Stock shall
not be sufficient to effect the exercise of this Warrant,  the Company will take
such  corporate  action as may be  necessary  to  increase  its  authorized  but
unissued  Common Stock to such number of shares as shall be sufficient  for such
purpose. The Company shall have analogous  obligations with respect to any other
securities or properties  issuable upon exercise of this Warrant.  The Company's
issuance of this Warrant shall constitute full authority to its officers who are
charged with the duty of
                                        4
<PAGE>
executing stock certificates to execute and issue the necessary certificates for
shares of Common Stock upon the exercise of this Warrant;

                  (b)      All Common Stock that may be issued upon  exercise of
the rights  represented by this Warrant will, upon issuance,  be validly issued,
fully paid,  nonassessable,  and free from all taxes,  liens,  and charges  with
respect to the issue thereof; and

                  (c)      All original  issue taxes payable with respect to the
issuance of shares upon the exercise of the rights  represented  by this Warrant
will be borne by the Company but in no event will the Company be  responsible or
liable for income taxes or transfer taxes upon the transfer of any Warrant.

         7.       No Stockholder Rights. Until exercised, this Warrant shall not
entitle the  Warrantholder to any voting rights or other rights as a stockholder
of the Company.  The rights of the Holder are limited to those expressed in this
Warrant and are not  enforceable  against  the Company  except to the extent set
forth herein.

         8.       Transfer Restrictions.

                  (a)      This  Warrant is not  transferable  except by will or
the laws of descent and distribution and, during Holder's lifetime,  it may only
be exercised by Holder.

                  (b)      Neither this Warrant nor the shares of stock issuable
upon the exercise hereof have been registered  under the Securities Act of 1933,
as amended (the "Securities  Act") or under any state securities laws and unless
so registered may not be transferred,  sold, pledged,  hypothecated or otherwise
disposed of unless an exemption  from such  registration  is  available.  In the
event Holder  desires to transfer  any of the shares of stock issued  hereunder,
the Holder must give the Company prior written notice of such proposed  transfer
including the name and address of the proposed transferee.  Such transfer may be
made only either (i) upon publication by the Securities and Exchange  Commission
(the  "Commission") of a ruling,  interpretation,  opinion or "no action letter"
based upon  facts  presented  to said  Commission,  or (ii) upon  receipt by the
Company of an opinion  of  counsel to the  Company in either  case to the effect
that the proposed  transfer will not violate the  provisions  of the  Securities
Act,  the  Securities  Exchange  Act of  1934,  as  amended,  or the  rules  and
regulations  promulgated  under  either  such act, or in the case of clause (ii)
above,  to the effect  that the shares of stock to be sold or  transferred  have
been  registered  under the Securities Act and that there is in effect a current
prospectus  meeting the  requirements of Subsection 10(a) of the Securities Act,
which is being or will be delivered to the  purchaser or  transferee at or prior
to the time of delivery of the certificates evidencing the shares of stock to be
sold or transferred.

                  (c)      Prior  to  any  such  proposed  transfer,  and  as  a
condition  thereto,  if such  transfer  is not  made  pursuant  to an  effective
registration  statement  under the Securities Act, the Holder will, if requested
by the Company,  deliver to the Company (i) an investment covenant signed by the
proposed  transferee,  (ii) an agreement by such transferee to the impression of
the
                                        5
<PAGE>
restrictive   investment   legend  set  forth  herein  on  the   certificate  or
certificates  representing the securities acquired by such transferee,  (iii) an
agreement by such  transferee that the Company may place a "stop transfer order"
with its transfer agent or registrar, and (iv) an agreement by the transferee to
indemnify the Company to the same extent as set forth in paragraph 8(d) below.

                  (d)      Holder   acknowledges  that  Holder  understands  the
meaning and legal  consequences  of this Section 8, and the Holder hereby agrees
to indemnify and hold harmless the Company, its representatives and each officer
and  director  thereof  from and against any and all loss,  damage or  liability
(including  all  attorneys'  fees and costs incurred in enforcing this indemnity
provision) due to or arising out of (i) the inaccuracy of any  representation or
the breach of any warranty of Holder  contained in, or any other breach of, this
Warrant  Agreement,  (ii) any  transfer of any of this  Warrant or the shares of
stock  issuable  hereunder in violation of the  Securities  Act, the  Securities
Exchange Act of 1934, as amended, or the rules and regulations promulgated under
either of such acts, (iii) any transfer of this Warrant or any of said shares of
stock not in accordance with this Warrant Agreement or (iv) any untrue statement
or  omission  to state  any  material  fact in  connection  with the  investment
representations or with respect to the facts and representations supplied by the
Holder to  counsel  to the  Company  upon  which its  opinion  as to a  proposed
transfer shall have been based.

                  (e)      Any assignment,  transfer,  pledge,  hypothecation or
other disposition of this Warrant  attempted  contrary to the provisions of this
Warrant  Agreement,  or any  levy of  execution,  attachment  or  other  process
attempted upon the Warrant, shall be null and void and without effect.

                  (f)      Unless the shares of stock  issuable  hereunder  have
been  registered  under the  Securities  Act,  upon exercise of this Warrant (in
whole or in part) and the  issuance of any of said  shares,  the  Company  shall
instruct its transfer  agent to enter stop transfer  orders with respect to such
shares,  and all  certificates  representing  said shares shall bear on the face
thereof  substantially  the  following  legend,  insofar as is  consistent  with
Arizona law:

                  "The shares of common stock  represented  by this  certificate
                  have not been registered  under the Securities Act of 1933, as
                  amended,  and may not be sold,  offered  for  sale,  assigned,
                  transferred  or  otherwise   disposed  of  unless   registered
                  pursuant  to the  provisions  of  that  Act or an  opinion  of
                  counsel  to  the  Company  is  obtained   stating   that  such
                  disposition is in compliance with an available  exemption from
                  such registration."

         9.       Termination of the Warrant. Notwithstanding anything herein to
the contrary,  this Warrant shall not be exercisable  after the earliest of: (i)
June 2, 2001; or (ii) one year after the date the Holder's  employment  with the
Company  terminates,  if such  termination  is the result of death or  permanent
disability.
                                        6
<PAGE>
         10.      No Guarantee of  Employment.  This  Agreement  shall in no way
restrict any right (which  might  otherwise  exist) of the Company or any of its
subsidiaries to terminate Holder's employment at any time.

         11.      Lost Certificate.  If this Warrant is lost, stolen,  mutilated
or destroyed,  the Company  shall,  on such terms as the Company may  reasonably
impose,  including a requirement that the  Warrantholder  obtain a bond, issue a
new Warrant of like denomination, tenor and date.

         12.      Binding Effect. This Warrant shall inure to the benefit of and
be binding upon the Warrantholder,  the Company and their respective  successors
and permitted assigns.

         13.      Company's  Notice of Certain  Events.  So long as this Warrant
shall be outstanding  and  unexercised (i) if the Company shall pay any dividend
or make any  distribution  upon the Common  Stock,  or (ii) if the company shall
offer to the holders of Common  Stock for  subscription  or purchase by them any
shares of stock of any class or any other  rights,  or (iii) in the event of any
capital  reorganization  of  the  Company,   reclassification  of  the  Company,
reclassification of the capital stock of the Company, consolidation or merger of
the Company with or into another  corporation,  sale, lease or transfer of shall
or  substantially  all of the  property  and  assets of the  Company  to another
corporation, or voluntary or involuntary dissolution, the Company shall cause to
be delivered to the Holder, at least ten days prior to the date specified in (a)
or (b) below, as the case may be, a notice containing a brief description of the
proposed  action and  stating  the date on which (a) a record is to be taken for
the   purpose  of  such   dividend,   distribution   or  rights,   or  (b)  such
reclassification,  reorganization,  consolidation,  merger,  conveyance,  lease,
dissolution, liquidation or winding up is to take place and the date, if any, is
to be fixed, as of which the holders of Common Stock of record shall be entitled
to  exchange  their  shares of Common  Stock for  securities  or other  property
deliverable upon such reclassification,  reorganization,  consolidation, merger,
conveyance, dissolution, liquidation or winding up.

         14.      Notice.  Notices and other  communications  to be given to the
Holder of the Warrants evidenced by this certificate shall be delivered by hand,

         15.      Governing Law. The validity,  interpretation,  and performance
of this Warrant and of the terms and provisions  hereof shall be governed by and
construed in accordance with

agent for the other.

                  b. It is  understood  and  agreed  that since  Reherman  is an
independent  contractor,  M.D. Labs will not carry insurance covering any aspect

that any action to enforce any provision of this Agreement shall be brought only

instance upon the strict  performance  of any provision of this  Agreement or to
exercise  any  election  contained  herein shall not be construed as a waiver or
relinquishment  for the  future  of such  provision  or  election.  No waiver or
modification  by any  party  shall  have been  deemed  to have been made  unless
expressed in writing by such party.

The following represents the Consulting Agreement (the "Agreement") between Chad

Inc.,  1719 West  University  Drive,  Suite  187,  Tempe,  Arizona,  85281  (the
"Company").

1. Consulting Services to be Performed:
- ---------------------------------------

The Consultant will conduct various research and development  projects and tasks
for the Company,  including  but not limited to  developing  and  targeting  new
health food  supplement  products,  primarily  herbal,  amino acid, and hormonal
products, which could reasonably and cohesively be integrated into the Company's
existing or proposed  product lines.  In any event,  the Consultant will only be
asked to perform such consulting  work in areas of his expertise.  Additionally,
the Consultant  will aid the Company in sourcing  suppliers of the raw materials
required  for  the  production,  and if  necessary  the  sub-contracting  of the
manufacturing of the products developed and sourced. The Consultant will perform
various research projects for the Company, as directed by Company officers,  and
the  Consultant  will  perform a minimum  of forty (40)  hours of  research  and
development work per month for the Company, either as directed by the Company or
self directed.

In the  course of  providing  the  Company  with the  research  and  development
services, the Consultant will also attempt to source potential operating company
and product line acquisitions ("Acquisition(s)") for the Company. The Consultant
agrees that he is not entitled to any  commissions  or finder's fees  associated
with any such Acquisition services.  However, the Company reserves the right, in
its sole  discretion,  to pay the Consultant a commission  for any  Acquisitions
sourced by the Consultant without  establishing  precedence for required Company
commission payments for any subsequent Acquisitions sourced by the Consultant.

2. Compensation and Duration of Agreement:
- ------------------------------------------

The Company will pay the Consultant one thousand five hundered  dollars ($1,500)
per month for performing the aforementioned  consulting services. The Consultant
agrees that he is not entitled to any royalty or  commission  payments  upon the
Company's sale of any products developed or sourced by the Consultant,  unless a
separate royalty or commission  agreement is prepared in writing and executed by
both the  Consultant and the Company.  The Consultant  will obtain prior written
approval  from a Company  officer  for all  expenses  for  which the  Consultant
desires reimbursement.

The terms of this Agreement are for six (6) months from October 1, 1996, and can
be renewable  for an  additional  six (6) months at the sole  discretion  of the
Company  provided  that both the  Consultant  and the  Company  execute  such an
extension agreement.

3. Product and Property Ownership:
- ----------------------------------

All research and development of any products,  trade names, trade marks, and any
other  tangible or  intellectual  property  developed by the  Consultant  either
independent of the Company or in conjunction  with Company  personnel,  prepared
during the period(s)  covered by this  Agreement are the property of the Company
and not the Consultant. The Consultant will work with the Company to assure that
all research and development  work is not obtained or utilized by any individual
or entity not a party to this
                                        1
<PAGE>
Agreement,  and will further aid the Company in obtaining legal ownership of all
products,  trade names,  trade  marks,  and any other  tangible or  intellectual
property developed by the Consultant.

4. Non-Compete and Confidentiality of Information:
- --------------------------------------------------

The Consultant  agrees not to compete in any manner with the Company,  including
any  competition  through any  Consultant  affiliated or related  entity for the
duration of this Agreement and for six (6) months  following the  termination of
the  Agreement.  The  Consultant  further  agrees  that  he  will  maintain  all
information  about the Company and all research work performed by the Consultant
in the strictest of confidence.

The Consultant acknowledges that the Company is in the latter stages of becoming
a publicly traded company,  and that the Company will become subject to numerous
laws imposed by the Securities and Exchange Commission,  and that the Consultant
may become privy to  confidential  Company  information.  Any such  confidential
"insider  information"  is to also be held in the strictest  confidence,  and no
trades of the Company's securities are to be executed by the Consultant based on
any such Company  "inside  information"  and that Consultant will be held solely
responsible for any disclosure of Company "inside  information"  and any illegal
security trades executed based on the Consultant's  disclosure or utilization of
such information.

5. Potential for Extended Relationship:
- ---------------------------------------

Should this Agreement  prove to be mutually  advantageous to both the Consultant
and the  Company,  the company  desires to extend the scope and services of this
Agreement,  possibly  allowing the Consultant to become a full-time  employee of
the  Company.  Any such  changes to this  Agreement  to that  effect  must be in
writing and executed by both the Consultant and the Company.

6. Purchases of Company Product:
- --------------------------------

The  Consultant  will be  entitled  to purchase  for retail  resale  purposes at
Powerhouse  Gym in Indiana,  any and all Company  products at Company  cost plus
postage,  for the  duration  of this  Agreement  and  during  the six (6)  month
non-compete  period.  The  Consultant  agrees  to be  practical  and  reasonable
regarding the purchase of Company products at cost, only ordering those products
actually required.

7. Severability:
- ----------------

If any provision of this  Agreement is found to be  unenforceable  by a court of
competent jurisdiction,  such finding shall not effect the enforceability of any
other provision(s) herein.

8. Governing Law and Venue:
- ---------------------------

This Agreement  shall be interpreted in accordance with the laws of the State of
Arizona,  and any actions  brought  relating to this Agreement shall lie only in
