REPORT.
 
ITEM 1. BUSINESS
 
GENERAL
 
    Irwin Naturals/4Health, Inc ("INH" or the "Company"), a Utah corporation,
formerly known as 4Health, Inc., is the surviving corporation of a merger (the
"Merger") of 4Health, Inc., a Utah corporation ("4Health") with Irwin Naturals,
Inc., a California corporation ("IN") consummated June 30, 1998. Pursuant to the
Merger, IN was merged with and into 4Health. Upon consummation of the Merger,
4Health changed its name to Irwin Naturals/4Health, Inc.
 
    Prior to the Merger, 4Health was a supplier and formulator of vitamins and
nutritional supplements designed and formulated to address the dietary needs of
the general public. 4Health's products are produced solely from natural
ingredients and are formulated for the purposes of achieving specific dietary or
nutritional goals.
 
    On July 16, 1996, 4Health emerged from an earlier merger between 4health
Inc., a California corporation ("Old 4health") and Surgical Technologies, Inc.,
a Utah corporation ("SGTI"). Subsequent to this merger, SGTI changed its name to
4Health, Inc. Old 4health was incorporated and commenced operations on February
17, 1993.
 
    In mid-1997, 4Health began a search for a strategic partner. 4Health
management believed that its lack of experience in the food, drug and mass
market was limiting its future sales growth and reducing 4Health's ability to
generate significant economies of scale with respect to the cost of goods sold.
As a result of this search, 4Health agreed to merge with IN. IN was organized in
August 1995 and formulated and distributed nutritional supplements through the
food, drug and mass market, internationally and through health food stores.
4Health chose IN as a strategic partner because of IN's significant
international and mass market sales in comparison to other potential partners.
 
    The Merger was accounted for under the "pooling-of-interests" method of
accounting, in accordance with generally accepted accounting principles. The
"pooling-of -interests" method is intended to present as a single interest the
4Health and IN common stockholder interests that were previously independent and
the combined rights and risks represented by those interests. This method
assumes that the stockholder groups neither withdraw nor invest assets but in
effect exchange voting common stock in a ratio that determines their respective
interests in the combined enterprise. The Merger resulted in the issued and
outstanding shares of common stock, no par value per share, of IN being
converted into an aggregate 15,750,000 shares of 4Health Common Stock.
 
    PRODUCTS
 
    The Company is a supplier and formulator of vitamins and nutritional
supplements that are manufactured primarily from natural herbs, botanicals and
nutrients. The Company has three broad categories of
 
                                       3
<PAGE>
products including: (i) cleansing products to eradicate the toxins from the
body; (ii) building products, including 151 Bars that increase the body's energy
and stamina through restoring vital nutrients to the appropriate levels; and
(iii) specific solutions for selected organ and body systems to concentrate on
an individual's problem areas. The Company's top brand names are: Nature's
Secret-Registered Trademark- (31.9% of 1998 revenue), Diet Systems
6-Registered Trademark- (14.9%), and Irwin Naturals-Registered Trademark-
(13.4%).
 
    With over 69 registered and pending trademarks worldwide, INH believes that
certain of its product formulas are proprietary and cannot be duplicated without
the master recipes, which are secured in safekeeping. The Company attempts to
protect its products and formulas with, among other things, "non-
disclosure/non-competition" agreements with its manufacturers and employees and
trademark protection. The formulations of INH's products were developed by the
Company's founders R. Lindsey Duncan, Chairman and a nutritionist certified by
the National Institute of Nutritional Education and Klee Irwin, Chief Executive
Officer. The Company trademarks all brand line names and most product names. The
Company further protects its trademarks by taking prompt action against
potential infringements.
 
    MANUFACTURING AND SUPPLY SOURCES
 
    All of the Company's products are manufactured by third party suppliers
pursuant to the Company's specifications and proprietary recipes. All of the
companies that manufacture for INH are required to meet strict manufacturing
standards required by the Food and Drug Administration ("FDA"). To date, the
Company has relied exclusively on domestic manufacturers in order to facilitate
quality assurance monitoring. Prior to selecting a manufacturer to produce its
products, INH reviews the manufacturer's raw material sources, quality assurance
procedures, and reliability to assure that the proposed manufacturer meets the
Company's criteria.
 
    The Company places purchase orders with its suppliers for individual product
manufacturing lots. Delivery of packaged and labeled products are made to the
Company's distribution center in Culver City, California. The Company has no
long-term manufacturing agreements with any of its suppliers, but purchases
manufactured lots pursuant to individual purchase orders. Currently, the Company
utilizes eight different manufacturers and believes that there are other
qualified manufacturers that would meet quality assurance requirements if
alternative manufacturing sources were required. The Company maintains an
inventory of approximately 60 to 90 days of anticipated demand and to date has
not experienced material shortages of manufactured products for delivery. All
ingredients in the Company's products are generally available from a number of
alternative sources, although certain of the ingredients, such as those based on
agricultural products, are subject to seasonal availability to a limited degree.
 
    MARKETING AND DISTRIBUTION
 
    The Company utilizes its marketing expertise to position and sell its
portfolio of branded products. The Company is continuing to build its portfolio
of consumer brands. The Company aims to achieve brand growth through
advertising, attractive packaging and favorable shelf positioning. This process
may be augmented through targeted brand acquisitions. The sales, marketing and
distribution infrastructure is designed to integrate new brands with minor
incremental costs and synergistic potential. Historically, the Company has
distributed its products though three main segments: mass market retailers (47%
of sales in 1998), specialty health food stores (43%) and internationally (10%).
Through advertising, the Company is able to convey the effectiveness of its
products. The Company has established its reputation with retailers through
quality products, timely delivery and superior packaging. Through its ability to
position products in the marketplace and its strong reputation, the Company has
been able to secure favorable shelf spacing from most of its retail customers.
 
    As a result of the Merger, INH is positioned to pursue a distribution
strategy of multiple brands within multiple retail channels. The Merger has
expanded the potential consumer base of 4Health
 
                                       4
<PAGE>
significantly, as 4Health and IN offer products in distinct product categories.
Since the Merger, merchandising vehicles which feature products from both lines
have met with acceptance and the Company has instituted cross-branding
incentives for retailers.
 
    In recognizing the need for strong operational management expertise, the
Company retained Louis Mancini, the former President of General Nutrition
Centers, as the President and Chief Operating Officer. Mr. Mancini began his
tenure at INH effective October of 1998.
 
    SALES
 
    Sales during 1998 were relatively flat compared to 1997 primarily due to the
fact that the Merger dissipated management energy and negatively impacted the
Company's ability to focus its attention upon the sales effort. As of December
31, 1998, the Company's backlog totaled $1,207,963 compared to $965,125 on
December 31, 1997.
 
    Throughout 1998, the Company took several critical steps that it hopes will
strengthen its future position. The Company made strategic decisions to develop
new areas of business by launching a nutritional bar product and by pursuing the
addition of pain relief products to its portfolio.
 
    CUSTOMERS CONCENTRATION
 
    The Company's top ten customers represented approximately 36.8% of its 1998
total revenues. Management believes that its business is sufficiently
diversified among its customers and additional efforts are underway to further
diversify the Company's revenues along both distribution channels and among
specific customers.
 
    COMPETITION
 
    The industry in which the Company operates is highly competitive and
fragmented. It is estimated that nearly 900 companies are involved in the
manufacturing or wholesale of supplements to the mass markets. Of those 900,
eleven companies comprise 25% of the market with the remaining 75% comprised
mostly of companies generating less than $20 million in total annual sales.
 
    The Company continues to be a leader in internal cleansing products and
intends to leverage this success to launch other products. INH's Nature's
Secret-Registered Trademark- and Harmony Formula-Registered Trademark- brand
lines have built strong brand loyalty with retailers, practitioners and
customers by delivering quality products, excellent customer service and an
emphasis on health through education.
 
    In the food, drug and mass market, the Company faces increased competition
where many of its competitors are significantly larger and have greater
financial resources. The Company believes it will be able to compete
successfully in this mass market because of its unique formulations and
packaging, product quality, and good relationships with distributors and store
buyers.
 
    EMPLOYEES
 
    As of the end of 1998 INH had 109 employees including Chairman, CEO,
President, two senior managers and eight middle managers, 16 individuals in
general administration, 40 individuals in sales and marketing, 39 individuals in
distribution and one in research and development. The Company's employees are
not represented by a collective bargaining organization, and the Company is not
aware of any efforts to organize any such collective bargaining unit. INH has
not experienced any work stoppages or slow downs.

RISKS RELATED TO THE BUSINESS OF IRWIN NATURALS/4HEALTH
 
    EXPANSION OF DISTRIBUTION CHANNELS
 
    The Company anticipates expanding current distribution channels, introducing
new products, entering new markets, and in general expanding its activities and
operations. Because of the nature of any such expansion, the accompanying
results of operations for previous periods may not necessarily be indicative of
the results of operations in the future. While INH has been successful in
expanding its markets and distributors to date there can be no assurance that it
will be able to successfully continue to expand in the future. Further, there
can be no assurance that expenditures of funds to expand current distribution
channels, introduce new products, enter new markets, and in general to expand
the Company's activities and operations will be successful in generating
incremental profitable revenue.
 
    DIFFICULTY OF STRICT COMPLIANCE WITH GOVERNMENT REGULATIONS
 
    The processing, formulation, packaging, labeling and advertising of the
Company's products are subject to regulation by more than one federal agency.
Congress has recognized the potential impact of dietary supplements in promoting
the health of US citizens by enacting the Dietary Supplement Health Education
Act of 1994 ("DSHEA"). Because of the broad language of certain sections of
DSHEA and the regulations which implement it, it is difficult for any company
manufacturing or making dietary supplements to remain in strict compliance.
 
    On November 24, 1997, the Commission on Dietary Supplement Labels, a seven
member group appointed by the President of the United States (the "DSL
Commission"), issued an 84 page report (the "Report") which includes many
recommendations for the regulation of label claims and statements for dietary
supplements. The DSL Commission's conclusions and advice are in the form of a
series of Findings and Guidelines and its ultimate recommendations are called
Recommendations. Section 12 of DSHEA requires the FDA to publish in the Federal
Register "a notice of any recommendation of the Commission for changes in
regulations of the Secretary for the regulation of dietary supplements and shall
include in such notice a notice of proposed rulemaking on such changes together
with an opportunity to present views on such changes."
 
    Based on the report, and pursuant to Section 12 of DSHEA, on April 29, 1998
the FDA published a proposed rule entitled "Regulations on Statements Made for
Dietary Supplements Concerning the Effect of the Product on the Structure or
Function of the Body" (the "S/F Rule"). This proposed rule, if made a final rule
(that is a regulation), would broaden what the FDA considers an impermissible
drug claim or disease claim for a dietary supplement. At the same time the S/F
Rule would restrict and narrow the permissible structure/function statements the
Company could make about the benefits of its products on the label and labeling
(brochures). Indirectly, this S/F rule would narrow the permissible claims the
Company could place in advertisements. The effective date of the regulation is
proposed as 30 days after the final rule is published in the Federal Register.
While there is no way the Company can predict the language of the resulting
regulation, based upon advice of their FDA counsel, the Company believes that
the S/F rule will not be issued in the form as published on April 29, 1998.
 
    CONCENTRATION OF CUSTOMERS
 
    INH received approximately 13.3% of its revenues from a single customer
(GNC) during 1998. The Company does not have any long-term contractual
relationship with this customer. The loss of this customer would have an adverse
impact on the business of INH.
 
    RELIANCE ON LIMITED NUMBER OF PRODUCTS
 
    The Company currently offers approximately 100 products and derived more
than 13% of its revenues during 1998 from the sale of one product, Ultimate
Cleanse-Registered Trademark-. As a result of the limited number of products
 
                                       6
<PAGE>
from which the Company derives its revenue, the risks associated with INH's
business increase since a decline in market demand for one or more products, for
any reason, could have a significant adverse impact on the Company.
 
    STRENGTH OF INH'S COMPETITORS
 
    Competition in the nutritional supplement industry is vigorous with a large
number of businesses engaged in the industry. Operations in the food, drug and
mass market exposes the Company to increased competition from vitamin and other
health related products that compete for the same shelf space. Many of these
competitors have established reputations for successfully developing and
marketing nutritional supplement products. Many of these companies have greater
financial, managerial, and technical resources than INH, which may put the
Company at a competitive disadvantage. If the Company is not successful in
competing in those markets, it may not be able to realize its business
objectives.
 
    DEPENDENCE ON MANAGEMENT
 
    The Company is dependent on its management for substantially all of its
business activities, including the development of new products and the
advancement of INH's identity and recognition in the nutritional supplement
industry. The loss of the services of certain members of management such as the
Chairman of the Board or Chief Executive Officer could have a material effect on
the business, operations and financial condition of the Company. INH is required
to maintain a key-man life insurance policy on the lives of the Chairman of the
Board and Chief Executive Officer in the amount of $5,000,000. Except for an
employment, intellectual property and non-compete agreement with Messrs. Duncan
and Irwin and a three year employment agreement with Mr. Louis Mancini,
President, INH has no long-term agreement with any executive officer or key
employee.
 
    NO LONG-TERM CONTRACTS WITH MANUFACTURERS OR DISTRIBUTORS
 
    The Company purchases all of its products from third-party manufacturers
pursuant to purchase orders issued from time to time by INH but without any
long-term manufacturing agreements. In the event that a current manufacturer is
unable to meet the Company's manufacturing and delivery requirements at some
time in the future, the Company may suffer interruptions of delivery of certain
products while it establishes an alternative source. To limit the Company's
exposure to this type of interruption, for all large volume products, two
third-party manufacturers have been established. For smaller volume products,
the selection of alternative manufacturing sources may be delayed while the
Company completes a review of the proposed manufacturer's quality control, raw
material sources, and manufacturing and delivery capabilities. To help mitigate
any interruption, the Company maintains a 60-90 day inventory on most products.
 
    CUSTOMER GUARANTY OF SATISFACTION; RIGHT OF RETURN
 
    In an effort to build customer confidence and satisfaction, INH warrants
satisfaction and grants to its customers the right of return for full credit any
product that is unsatisfactory to the customer or that is shelf-worn or stale
merchandise. Although the Company has had this policy since its inception and
experienced product returns of only approximately 5% of gross sales in 1998,
there can be no assurance that such a policy will not result in additional
product returns in the future as the Company expands its product lines and
enters new markets.
 
    POTENTIAL TRADEMARK INFRINGEMENT
 
    The conduct of INH's business, in common with other sellers of branded
consumer products, may involve from time to time potential liability for
trademark infringement. The Company is engaged on a continuing basis in
developing brand names for its new products, securing trademark protection for
brand
 
                                       7
<PAGE>
names and copyright protection for associated materials, policing its existing
marks, and enforcing its legal rights in cases of potential infringement by
third parties of its legally protected marks and copyrights. Prior to commencing
advertising and sales of products under a newly developed brand name, the
Company seeks to minimize the risks of potentially infringing the rights of
third parties by conducting trade and service mark searches and other inquiries
in addition to filing publicly for trademark protection of the brand name and
copyright protection for associated advertising materials and labeling. The
Company registers for its principal product lines as well as its principal
products. Notwithstanding such efforts, there can be no assurance that the
Company will not suffer adverse financial consequences as a result of legally
established third party claims to first use of trade or service marks used by
the Company.
 
    YEAR 2000
 
    THE Y2K PROBLEM.
 
    INH has conducted a review of its respective computer systems to identify
the systems that could be affected by the Y2K issue. The Y2K problem is the
result of computer programs being written using two digits rather than four to
define the applicable year. Any of the Company's programs that have time-
sensitive software or equipment that has time-sensitive embedded components may
recognize a data using "00" as the year 1900 rather than the year 2000. This
could result in a major system failure or miscalculations.
 
    While some upgrades will be necessary, the Company presently believes that
the Year 2000 problem will not pose significant operational problems for the
Company's computer systems. Additionally, the Y2K problem is not expected to
have a material effect on the cost of operation of the Company.
 
    The Company also may be vulnerable to other companies' Y2K issues. The
Company's current estimates of the impact of the Y2K problem on its operations
and financial results do NOT include costs and time that may be incurred as a
result of any vendors' or customers' ("third-party") failure to become compliant
on a timely basis. The Company has initiated formal communications with its
significant vendors and customers with respect to such persons' Y2K compliance
programs and status. However, there can be no assurance that such other
companies will achieve Y2K compliance or that any conversions by such companies
to become Y2K compliant will be compatible with the Company's computer system.
The inability of the Company or any of its principal vendors or customers to
become Year 2000 compliant in a timely manner could have a material adverse
effect on the Company's financial condition or results of operations.
 
    A Y2K task force has been established. The task force has not developed a
"Worst Case" scenario for an overall Y2K contingency plan and does not plan to
do so unless; as a result of its ongoing Y2K review, management believes such
plans are warranted. The only contingency plan to be developed and implemented
will be as a result of a comprehensive survey being conducted on suppliers and
key third parties of their IT systems, including computer applications,
operating systems, and all non-IT related systems, including embedded
applications and equipment. The focus of the survey is to ensure that key third
parties are Y2K compliant by the end of the year.
 
    The Company has identified high risk applications that are critical to its
business, recognizing the fact that timely Year 2000 compliance of these systems
is crucial, and therefore, has designed its plan to address these systems first.
 
    The Company's plan includes remediating certain existing software. The plan
is underway and the Company believes it will be completely in effect by the end
of October, 1999.
 
    ADDRESSING THE PROBLEM.
 
    The Company predicts a six-phase approach to resolving the Y2K issues that
are reasonably within its control. All of these efforts are being coordinated
through Company's Director of Information Systems
 
                                       8
<PAGE>
(I.S.). The Director of I.S. reports to the Audit Review Committee comprised of
Daniel Martin, Chief Financial Officer and Louis Mancini, President, with
respect to the Company's Y2K efforts.
 
    The Company's approach to, and the anticipated timing of each phase are
described below.
 
    PHASE 1--INVENTORY.  The first phase entails a corporate-wide inventory of
all hardware and software (including business and operational applications,
operating systems and third-party products) that may be at risk, and
identification of key third-party businesses whose Y2K failures might most
significantly impact the Company. The IT system inventory process has been
completed, and the inventories of key third-party businesses and of internal
non-IT systems are expected to be completed by April 30, 1999.
 
    PHASE 2--ASSESSMENT.  Once each at-risk system has been identified, the MIS
department assesses how critical the system is to business operations and the
potential impact of failure, in order to establish priorities for repair or
replacement. Systems are classified as "critical," "important" or
"non-critical." A "critical" system is one that, if not operational, would cause
the shutdown of all or a portion of a business unit within two weeks, while an
"important" system is one that would cause such a shutdown within two months.
This process has been completed for all IT systems. The assessment process for
internal non-IT systems and for key third-party businesses is expected to be
completed by June 1999. Systems that are known to be critical or important are
receiving top priority in assessment and remediation.
 
    PHASE 3--STRATEGY.  This phase involves the development of appropriate
remedial strategies for both IT and non-IT systems. These strategies may include
repairing, testing and certifying, replacing or abandoning particular systems
(as discussed under Phases 4 and 5 below). Selection of appropriate strategies
is based upon such factors as the assessments made in Phase 2, the type of
system, the availability of a Y2K-compliant replacement and cost. The strategy
phase has been completed for all IT systems. For some non-IT embedded systems,
strategy development is continuing. A strategy for addressing embedded systems
in office buildings currently occupied, and those anticipated to be occupied, is
being developed in concert with building managers and systems vendors and should
be completed by July 1999. The process of analysis, certification or replacement
or "workaround" for embedded systems in office buildings is expected to consume
the first half of 1999. Strategies for other embedded systems, such as satellite
communications systems, are being developed and are also expected to be complete
by mid-1999.
 
    PHASE 4--REMEDIATION.  The remediation phase involves creating detailed
project plans, marshalling necessary resources and executing the strategies
chosen. For IT systems, this phase is approximately 90% complete for critical
and important systems, and is expected to be completed (including certification)
by July 31, 1999. For non-critical systems, most corrections are expected to be
completed by October 31, 1999. For those systems that are not expected to be
reliably functional after January 1, 2000, detailed manual workaround plans will
be developed prior to the end of 1999.
 
    PHASE 5--TESTING AND CERTIFICATION.  This phase includes establishing a test
environment, performing systems testing (with third parties if necessary), and
certifying the results. The certification process entails having functional
experts review test results, computer screens and printouts against
pre-established criteria to ensure system compliance. The Company expects all
critical and important IT systems to be certified by September 30, 1999. Testing
for non-IT systems has been initiated; however, due to the Company's reliance on
many third-party vendors for these systems, the Company cannot estimate
precisely when this phase will be completed. The Company's target for all
critical and important non-IT systems is August 1999. The Company has initiated
written and telephonic communications with key third-party businesses, as well
as public and private providers of infrastructure services, to ascertain and
evaluate their efforts in addressing Y2K compliance. It is anticipated that the
majority of testing and certification with these entities will occur in 1999.
 
    PHASE 6--CONTINGENCY PLANNING.  This phase involves addressing any remaining
open issues expected in 1999 and early 2000. As a precautionary measure, the
Company is currently developing contingency
 
                                       9
<PAGE>
plans for all systems that are not expected to be Y2K compliant by July 1999. A
variety of automated as well as manual fallback plans are under consideration,
including the use of electronic spreadsheets, resetting system dates to 1972, a
year in which the calendar coincides with that of 2000, and manual workarounds.
The Company estimates that all of these plans will be completed by December
1999.
 
    COSTS.
 
    The estimated additional costs to complete the project are currently
expected to be approximately $20,000. A significant portion of these costs will
not be incremental, but rather reflect redeployment of internal resources from
other activities. The Company does not expect these redeployments to have a
material adverse effect on other ongoing business operations of the Company,
although it is possible that certain maintenance and upgrading processes will be
delayed as the result of the priority being given to Y2K remediation. All of the
costs of the Y2K project are being borne out of the Company's operating cash
flow.
 
    Based upon its efforts to date, the Company believes that the vast majority
of both its IT and its non-IT systems, including all critical and important
systems, will remain up and running after January 1, 2000. Accordingly, the
Company does not currently anticipate that internal systems failures will result
in any material adverse effect to its operations or financial condition. During
1999, the Company will also continue and expand its efforts to ensure that major
third-party businesses and public and private providers of infrastructure
services, such as utilities, communications services and transportation, will
also be prepared for the year 2000, and to develop contingency plans to address
any failures on their part to become Y2K compliant. At this time, the Company
believes that the most likely "worst-case" scenario involves potential
disruptions in areas in which the Company's operations must rely on such third
party vendors whose systems may not work properly after January 1, 2000. In
addition, the Company's international operations may be adversely affected by
failures of businesses in other parts of the world to take adequate steps to
address the Y2K problem. While such failures could affect important operations
of the Company, either directly or indirectly, in a significant manner, the
Company cannot at present estimate either the likelihood or the potential cost
of such failures.
 
    The nature and focus of the Company's efforts to address the Year 2000
problem may be revised periodically as interim goals are achieved or new issues
are identified. In addition, it is important to note that the description of the
Company's efforts necessarily involves estimates and projections with respect to
activities required in the future. These estimates and projections are subject
to change as work continues, and such changes may be substantial.
 
    Other than the cost of the new software and hardware to be implemented
corporate-wide, the Company has spent nominal amounts on the Y2K issue, and does
not expect any significant future expenditure. Although the task force expects
its cost estimates to be relatively accurate, it can not assure nor guarantee
that these costs will not increase or that the proposed solutions will be
installed on schedule by the date estimated.

RESULTS OF OPERATIONS
 
1998 COMPARED TO 1997
 
    Net Sales for the year ended December 31, 1998 rose to $30,547,000 from
$29,353,000, an increase of 4.1% when compared to 1997. Several products were
repositioned and remarketed after the merger as a result of new management's
focus on optimizing each product's potential. This repositioning resulted in a
one-time reduction of $387,000 (1.3%) in net sales. The improvement in net sales
between periods was due primarily to an increase in the Mass Market business,
with strong first quarter sales indicative of a high level of interest in
several major products introduced in the last half of 1997, greater market
penetration, and a strong focus on expanding into drug and discount chains in
the second, third, and fourth quarters. In addition, the last half of the year
saw the promising early signs of acceptance of the Company's newly introduced
Nutrition Bar. The relatively stable health food store sales are a reflection of
continued competitive pressures and an overall weakness in this sector of the
marketplace. International sales improved over 1997 as the newly installed
International Sales Division staff expanded strongly into several new strategic
markets.
 
    Gross Profit Margins rose to $17,602,000 in 1998 from $15,790,000 in 1997,
an increase of 11.5%. The post-merger product repositionings resulted in a
one-time $172,000 (1.1%) decrease in Gross Margins. Gross Margin as a percentage
of net sales increased to 57.6% of net sales in 1998 from 53.8% of net sales in
1997. This increase was due primarily to an improved product sales mix, and
reflective of continued internal efforts to lower the cost of the core products.
Improved margins were particularly evident in the Nature's
Secret-Registered Trademark- and Harmony Formula-Registered Trademark- branded
products.
 
    Total Selling, General & Administrative (SG&A) Expenses decreased by
$1,451,000 (8.4%) to $15,775,000 in 1998 from $17,226,000 in 1997. This
improvement was further reflected as SG&A Expenses decreased as a percentage of
net revenue to 51.6% in 1998 from 58.7% in 1997. Sales & Marketing Expense in
1998 accounted for $3,195,000 of the change as they decreased from $9,583,000 in
1997 to $6,388,000 in 1998, a 33.3% improvement. Much of the decrease in Sales &
Marketing expense was attributable to the synergies achieved as a result of the
merger. General and Administrative expense increased to $9,387,000 in 1998 from
$7,643,000 in 1997. The 1998 General & Administrative expenses, when adjusted
for merger related expenses of $1,614,000, were $7,773,000, a net increase of
$130,000
 
                                       14
<PAGE>
compared to the 1997 General & Administrative expenses of $7,643,000. Included
in the 1997 General & Administrative expenses are Research & Development (R & D)
expenses of $418,000. R & D expenses decreased to $29,000 in 1998 as the Company
relied on existing, developed products. The increase of $519,000 in the other
General & Administrative expenses in 1998 compared to 1997 was due to the
Company's investment in infrastructure to support anticipated growth in 1999.
 
    During 1997, the Company wrote off goodwill in the amount of $3,202,000 in
connection with the 1996 merger with SGTI. There was no similar expense in 1998.
 
1997 COMPARED TO 1996
 
    Net Sales for the year ended December 31, 1997 rose to $29,353,000 from
$28,592,000 in 1996, an increase of 2.7%. Irwin Naturals net sales increased
from $11,240,000 in 1996 to $16,921,000 in 1997, an increase of 50.5% while
4Health net sales decreased from $17,352,000 in 1996 to $12,432,000 in 1997, a
decrease of 28.4%. A large one-time sale in 4Health of approximately $5,000,000
in 1996 was a contributing reason to the decline in 4Health sales from 1996 to
1997.
 
    Gross Profit Margins declined to $15,790,000 in 1997 from $16,266,000 in
1996, a decrease of 2.9%. Gross Margins during this period increased at Irwin
Naturals from $5,839,000 in 1996 to $9,481,000 in 1997, a 62.4% increase.
4Health Gross Margins decreased during this same period from $10,427,000 in 1996
to $6,309,000, a decrease of 39.5%. Much of the decrease in 4Health Gross
Margins were due to the higher than normal margins in 1996 due to the large
one-time sale. Gross Margin as a percentage of net sales decreased to 53.8% of
net sales in 1997 from 56.9% of net sales in 1996. During this period Irwin
Gross Margins increased from 51.9% in 1996 to 56.0% in 1997, while 4Health Gross
Margins decreased from 60.1% in 1996 to 50.7% in 1997.
 
    Total SG&A Expenses decreased by $338,000 (1.9%) to $17,226,000 in 1997 from
$17,564,000 in 1996. Sales and Marketing expenses improved to $9,583,000 in 1997
from $10,831,000 in 1996, an 11.5% decrease. This improvement was partially due
to non-recurring advertising expenses in 1996 as a result of a targeted
advertising campaign. General and Administrative expenses increased to
$7,643,000 in 1997 from $6,733,000 in 1996, an increase of 13.5%. This
difference was attributable to Irwin Naturals as they began to create
infrastructure to support their 50.5% growth.
 
    The Company wrote off $3,202,000 of goodwill associated with SGTI during
1997.
 
1996 COMPARED TO 1995
 
    Net Sales for the year ended December 31, 1996 rose to $28,592,000 from
$12,824,000 in 1995, an increase of $15,768,000, or 123.0%. Irwin Naturals
increased from $2,390,000 in 1995 to $11,240,000 in 1996, an improvement of
$8,850,000 (370.3%). Irwin's increase contributed 56.1% of the overall net sales
increase. Irwin started its operations in August 1995. 4Health net sales
improved from $10,434,000 in 1995 to $17,352,000 in 1996, an increase of
$6,918,000 (66.3%). 4Health contributed 43.9% of the overall net sales increase.
Nearly $5,000,000 increase from 1995 to 1996 for 4Health resulted from a
non-recurring sale to a single customer. The year-to-year increase in net sales
can be attributed to highly energized and focused sales and marketing efforts on
the part of both companies.
 
    Gross Profit Margins improved to $16,266,000 in 1996 from $7,620,000 in
1995, an increase of $8,646,000 or 113.5%. Gross Margins during this period
increased at Irwin Naturals from $988,000 in 1995 to $5,839,000 in 1996, a 491%
increase. 4Health Gross Margins also increased during this same period from
$6,631,000 in 1995 to $10,427,000 in 1996, an increase of 57.2% in 1996. During
the same period, Gross Margin as a percentage of net sales decreased at 4Health
from 63.6% in 1995 to 60.1% of net sales in 1996.
 
    Total SG&A Expenses increased by $11,286,000 (179.8%) to $17,564,000 in 1996
from $6,278,000 in 1995. Sales and Marketing expenses increased to $10,831,000
in 1996 from $4,225,000 in 1995, an increase of 156.4%. 4Health accounted for
the majority of the increase as it increased its advertising expenses with a
Television Advertising campaign, and built up the outside sales forces, sales
management, and marketing
 
                                       15
<PAGE>
management for its brands. General and Administrative expenses increased to
$6,733,000 in 1996 from $2,052,000 in 1995, while both Irwin Naturals and
4Health invested heavily in building corporate infrastructure by adding
additional personnel, improving systems, and in the case of 4Health incurring
the additional expenses necessary to operate as a public company.
 
LIQUIDITY AND CAPITAL RESOURCES
 
    During the past three years, the Company has financed its business growth
primarily through operations and short-term borrowings.
 
    The Company's Cash position at December 31, 1998 was $426 thousand compared
to $637 thousand at December 31, 1997. As of December 31, 1998, the Company had
Working Capital of $4.395 million with a 1.8 to 1 Working Capital Ratio.
 
    Accounts Receivable totaled $6.023 million at December 31, 1998 as compared
to $4.9 million on December 31, 1997, an increase of $1.23 million, or 22.9%.
This increase was due primarily to increased sales revenue overall, a
disproportionate number of large sales in November and December, and a longer
collection cycle in the Company's fastest growing market segment, the mass
market.
 
    Inventories were valued at $2.855 million at December 31, 1998 as compared
to $2.162 million at December 31, 1997, which represents a 32.1% increase of
$.693 million. Management has concluded that Inventory levels at December 31,
1998 are at a level necessary to support the level of sales projected for the
fourth quarter of the year.
 
    Capital Expenditures for the year ended December 31, 1998 were $350 thousand
compared to $216 thousand for the same period in 1997, reflecting the cost of
creating new infrastructure support capabilities, and improving capacity.
 
    Other Assets have increased slightly from $648 thousand at December 31, 1997
to $749 thousand at December 31, 1998, an increase of $101 thousand, or 15.6%.
This increase stemmed primarily from a Note Receivable from Officer.
 
    Accounts Payable and Accrued Liabilities decreased $363 thousand, or 10.6%,
to $3.795 million from $3.432 million. The primary reason for the increase in
overall Inventory levels of 32.1%.
 
    As of December 31, 1998 the Company had a $1 million Line of Credit with
Alliance Bank, which had an outstanding balance of $1 million, and a $1.5
million Line of Credit with Norwest Bank, which had no outstanding borrowings.
 
    The Company has generated an overall negative cash flow of $211 thousand for
the year ended December 31, 1998 compared to a negative cash flow of $731
thousand for the same period in 1997. The majority of this improvement was due
to improved profitability, offset slightly by increased Inventory levels.
 
    The company's future capital requirements will depend on many factors,
including the nature and timing of orders from customers, collection of accounts
on trade sales, the expansion of sales and marketing efforts, costs associated
with entering into new channels of distribution, and the status of competitive
products.
 
    At December 31, the Company was in active negotiations with Wells Fargo Bank
to develop the terms of a $5 million Secured Line of Credit. This Line was
established in February of 1999 and expires on June 30, 1999.
 
    Subsequent to December 31, 1998, the Company entered into two acquisitions.
Effective February 15, 1999, the Company purchased the issued and outstanding
shares of Health & Vitamin Express, Inc. Although the purchase price of this
acquisition is to be paid in shares of Company stock, the Company is obligated
to invest or contribute to the acquired operations a minimum of $10 million
during the 36 months period subsequent the acquisition date, of which $4 million
must be invested or contributed within the first 18 months. Further, effective
March 10, 1999, the Company purchased certain assets and liabilities
 
                                       16
<PAGE>
of Inholtra Investment Holding and Trading, N.V., Inholtra, Inc. and Inholtra
Natural, Ltd. for $13,250,000. Of this total purchase price, $3,250,000 was paid
in cash, and the remaining $10 million is payable through a promissory note due
on June 10, 1999 secured by the acquired assets. These acquisitions have
significantly increased the Company's funding requirements.
 
    The Company is currently seeking to raise additional financing to meet the
increased funding requirements resulting from these acquisitions as well as to
satisfy anticipated sales growth and operational requirements. Management
believes that the Company will be able to successfully obtain the necessary
financing.
 
    There can be no assurance, however, that the Company will not require
additional financing earlier than anticipated, or that any additional financing
will be available at acceptable terms, if at all. The inability to obtain such
financing could have a material adverse effect on the Company's business,
financial condition, and results of operations.
 
SEASONALITY AND QUARTERLY FLUCTUATIONS
 
    The business is to some extent cyclical, but not necessarily seasonal.
 
    The following table sets forth, certain unaudited results of operations for
each quarter during 1997 and 1998. The unaudited information has been prepared
on the same basis as the audited financial statements appearing elsewhere in
this report and includes all adjustments, consisting of normal recurring
adjustments, which management considers necessary for a fair presentation of the
financial data shown. The operating results for any quarter are not necessarily
indicative of the results to be attained for any future period.

NEW AUTHORITATIVE PRONOUNCEMENTS
 
    The Financial Accounting Standards Board has issued SFAS No. 132,
"Employer's Disclosure about Pensions and Other Postretirement Benefits" and
SFAS No. 133, "Accounting for Derivative and Hedging Activities." These new
accounting standards do not have any impact on the Company's financial
statements or financial reporting.

credit amended to $6,400,000 in March 1999, subject to varying interest rates.
The Company will monitor the level of risk by keeping variable rate exposures at
acceptable levels.

ITEM 10. DIRECTORS AND EXECUTIVE OFFICERS OF THE REGISTRANT (CONTINUED)
private capital management division at Trust Services of America (TSA) served as
its Chief Investment Officer and President of TSA Capital Management.
 
    Prior to the Merger, the Company's Board of Directors was comprised of R.
Lindsey Duncan, Cheryl Wheeler, Rockwell D. Schutjer and Steven B. Beckman.
Subsequent to the Merger, the Board of Directors of the Company was comprised of
R. Lindsey Duncan, Klee Irwin, Jonathan Diamond, and James Jeffs. The Board of
Directors met six times during 1998 for regular Board of Directors meetings. All
directors attended 100% of the aggregate of (i) the total number of meetings of
the Board of Directors held while they were members and (ii) the total number of
meetings held by all Committees of the Board of Directors on which they served
as members. In addition, on several occasions, the Board of Directors gave their
unanimous written consent on issues involving normal corporate business. The
Board of Directors has three standing committees, the Audit Committee, the
Compensation Committee, and the Long-Term Stock Incentive Plan Administration
Committee ("LTSIP Administration Committee"). During 1998, the Audit Committee
and the LTSIP Administration Committee were composed of Messrs. Crosland and
Beckman prior to the Merger and Messrs. Diamond and Jeffs thereafter. The Audit
Committee did not meet during 1998, the functions of such committee being
performed by the Board of Directors as a whole. The LTSIP Administration
Committee met throughout 1998 as needed to grant stock options. The LTSIP
Administration Committee is responsible for overseeing 4Health's Long-Term Stock
Incentive Plan (the "LTSIP") including, subject to the express terms of the
LTSIP, making awards, interpreting the LTSIP, amending and rescinding rules and
other duties related to the proper implementation of the LTSIP. During 1998, the
Compensation Committee was composed of Messrs. Duncan and Irwin. The
Compensation Committee met once in 1998. The primary responsibility of the
Compensation Committee is to establish and review the compensation policies of
INH, including those for executives. During 1998, INH did not have a nominating
committee, the functions of such a committee being performed by the Board of
Directors as a whole.
 
    The LTSIP provides that upon assuming office, each non-employee director
shall be granted a non-qualified option to acquire 5,000 shares of Common Stock
at an exercise price equal to 100% of the fair market value on the date of
grant. One-half of the grant shall become exercisable upon completion of one
year of service as a director and the remaining balance upon completion of two
years of service as a director. All options have a five year expiration term.
 
    In addition, Messrs. Diamond and Jeffs were granted by the Board an
additional 20,000 shares each upon becoming directors. Half of these shares are
vested on June 30, 1999 and the other half on June 30, 2000.
 
    Directors do not receive compensation for attending meetings of the Board of
Directors. Directors are reimbursed for their reasonable travel and lodging
expenses incurred attending meetings.
 
SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE
 
    Pursuant to Section 16(a) of the Securities Exchange Act of 1934, executive
officers, directors and 10% shareholders of INH are required to file reports on
Form 3, 4 and 5 of their beneficial holdings and transactions in the INH Common
Stock. During 1998, all such reports were filed in a timely manner.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
    R. Lindsey Duncan, Chairman of the Board and Klee Irwin, Chief Executive
Officer, served on the Compensation Committee of the Board of Directors during
1998.
 
REPORT ON EXECUTIVE COMPENSATION
 
    The Compensation Committee of the Board of Directors has responsibility for
making recommendations regarding compensation policy for INH, including
executives. The Compensation Committee's overall goal is to provide a strong
link among shareholder value, Company performance, and executive compensation.
An additional goal is to promote long-term growth and development for INH by
attracting and retaining qualified and talented executives. The following report
shall not be deemed incorporated by reference into any filing under the
Securities Exchange Act of 1933 or the Securities Exchange Act of 1934.
 
    COMPENSATION COMMITTEE REPORT
 
    INH uses various compensation surveys, including industry and regional
specific surveys, to develop its compensation strategy and plans. The
Compensation Committee also refers to such surveys for executive compensation,
including that of the Chairman of the Board and the Chief Executive Officer.
 
    There is no set policy for adjusting base salary or bonuses subsequent to
initial employment. Such adjustments in the past have occurred due to changes in
job skills, performance, and competitive salary information.
 
    INH's current stock option plan includes executives, managers and key
employees. Stock options are granted periodically by the LTSIP Administration
Committee of the Board of Directors. The Long-Term Stock Incentive Plan allows
the grant of options, both incentive and non-qualified. Historically, the LTSIP
Administration Committee has granted non-qualified options. For executives, the
options are usually granted with one third vesting after each year of service
with INH. Pricing of the options generally begins at the fair market price on
the date of grant for the options vested after one year and increases $1.00 per
share for each additional year of service.
 
    The compensation given to INH's executives and senior officers for 1998 is
shown in the Summary Compensation table. The Compensation Committee believes
that the compensation awarded Messrs. Duncan and Irwin adequately reflects their
performance as INH's Chairman of the Board and Chief Executive Officer
respectively.
 
    The Compensation Committee has reviewed INH's compensation plans with regard
to the deduction limitations under the Omnibus Budget Reconciliation Act of 1993
(the "Act") and the final regulations interpreting the Act which have recently
been adopted by the Internal Revenue Service and the Department of the Treasury.
Based on this review, the Committee has determined that INH's LTSIP, as
previously approved by shareholders, meets the requirements for deductibility
under the Act. The Committee believes that no tax deduction will be lost as a
result of Section 162(m) on compensation paid to Company executives in 1998.
 
                                          R. Lindsey Duncan

EMPLOYMENT AGREEMENTS
 
    Upon the consummation of the Merger, both Mr. R. Lindsey Duncan and Mr. Klee
Irwin entered into substantially similar three year employment agreements with
the Company. Mr. Duncan is employed as Chairman of the Board and as a member of
the Executive Committee with all duties and responsibilities normally associated
with this position. Mr. Irwin is employed as the Chief Executive Officer and as
a member of the Executive Committee with all duties and responsibilities
normally associated with this position. In October of 1998, the Company entered
into an agreement to hire Mr. Louis Mancini as President and Chief Operating
Officer.
 
    These employment agreements provide for: (i) annual salaries of $225,000,
$350,000 and $250,000 for Messrs. Duncan, Irwin and Mancini respectively; (ii)
the right for Messrs Duncan and Irwin to receive an annual bonus equal to 2% of
the consolidated earning before income taxes in excess of $6,000,000; and (iii)
the right to participate in all retirement and welfare, benefit, fringe,
perquisite and other plans and programs applicable generally to other key
executives in effect at any time. In addition, all the above are entitled to
reimbursement for their reasonable business expenses.
 
STOCK PERFORMANCE
 
    The graph below presents a comparison of the cumulative shareholder return
of the Company's Common Stock over the period July 17, 1996 to December 31, 1998
with the cumulative total return over the same period for The Nasdaq Stock
Market--U.S. Companies Total Return Index and a peer group represented by the
Nasdaq Pharmaceutical Stocks Total Return Index (SIC code 283). Both indexes
were prepared for Nasdaq by the Center for Research in Security Prices. The
graph below compares the cumulative total return of INH's Common Stock over the
July 17, 1996 to December 31, 1998 period assuming a $100 investment on July 17,
1996 and assuming reinvestment of all dividends. (INH's Common Stock commenced
trading on the Nasdaq National Market tier of The Nasdaq Stock Market under the
stock symbol HHHH on July 17, 1996. Prior to that date, 4Health was known as
Surgical Technologies, Inc. with stock trading under the symbol SGTI. The prior
market performance history of SGTI has not been included herein because it does
not reflect the results of 4Health Inc. and Surgical Technologies, Inc. (the
"Surgical Merger") or the changed nature of the Company's business since the
Surgical Merger. The graph is based on daily total return figures from July 17,
1996 and month-end figures from July 30, 1996 through December 31, 1998).

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To Irwin Naturals/4Health, Inc.:
 
    We have audited the accompanying balance sheets of Irwin Naturals/4Health,
Inc. (a Utah corporation) as of December 31, 1997 and 1998, and the related
statements of operations, shareholders' equity and cash flows for each of the
three years in the period ended December 31, 1998. These financial statements
are the responsibility of the Company's management. Our responsibility is to
express an opinion on these financial statements based on our audits.
 
    We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
    In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Irwin Naturals/4Health, Inc.
as of December 31, 1997 and 1998, and the results of its operations and its cash
flows for each of the three years in the period ended December 31, 1998 in
conformity with generally accepted accounting principles.

3.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
    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.
 
    BUSINESS SEGMENTS
 
    The Company operates as one reportable business segment. The former Irwin
Naturals and 4Health, Inc., now the Company, sell branded natural health, herbal
and nutritional supplement products. The products are sold through mass retail,
specialty natural health, nutrition and food retail stores. The product sales
from each former company share similar profitability margins.

3.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    CONCENTRATION OF RISK
 
    Accounts receivable are unsecured and the Company is at risk to the extent
such amounts become uncollectable. At December 31, 1997, one customer
represented 28.1 percent of accounts receivable. At December 31, 1998, two
customers represented 25.5 and 10.9 percent of accounts receivable,
respectively.
 
    The Company had sales to a single customer that represented 23.5, 15.6 and
13.3 percent of net sales in 1996, 1997 and 1998, respectively.
 
    The Company's foreign sales represented 9.6, 14.1 and 10.0 percent of total
net sales in 1996, 1997 and 1998, respectively.
 
    During 1998, approximately 77 percent of the Company's total purchases were
from a single supplier. Management believes that if the Company was unable to
make further purchases from this supplier, it would be able to find alternative
suppliers with terms and quality levels similar to those currently in place.
 
    INVENTORIES
 
    Inventories are valued at the lower of cost (first-in, first-out) or market
and are summarized as follows:

</TABLE>
 
    PROPERTY AND EQUIPMENT
 
    Property and equipment are stated at cost. Depreciation and amortization are
computed using the straight-line method over the following estimated useful
lives:
 
<TABLE>
<S>                                                             <C>
                                                                     3 to 10
Machinery and equipment.......................................         years
Furniture and fixtures........................................  3 to 7 years

Leasehold improvements........................................         lease
</TABLE>
 
    When an asset is sold or otherwise disposed of, the cost and related
accumulated depreciation are removed from the accounts and any resulting gain or
loss are included in results of operations. Repairs and maintenance are charged
to expense as incurred and major replacements or betterments are capitalized.
 
    INTANGIBLES
 
    The Company acquired ID Technology in connection with a 1996 merger with
Surgical Technologies. ID Technology is used in angioplasty procedures. The
technology is being amortized using the straight-line method over an 8-year
period. Management believes the carrying value of the ID Technology is fully
recoverable.

3.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    TRADEMARKS
 
    Costs associated with the establishment and defense of trademarks have been
capitalized and are being amortized over seventeen years using the straight-line
method.
 
    REVENUE RECOGNITION
 
    The Company recognizes revenue at the time of shipment. Provisions for
returns and allowances are recorded as products are shipped. During the years
ended 1996, 1997 and 1998, the Company provided $181,000, $2,549,000 and
$2,116,000, respectively, for returns and allowances, including allowances for
doubtful accounts, and incurred related write-offs of $154,000, $2,288,000 and
$1,426,000, respectively.
 
    STOCK BASED COMPENSATION
 
    The Company adopted Statement of Financial Accounting Standards (SFAS) No.
123, "Accounting for Stock Based Compensation" (SFAS 123) in fiscal 1996. As
allowed by SFAS 123, the Company has elected to continue to measure compensation
cost under Accounting Principles Board Opinion No. 25, "Accounting for Stock
Issued to Employees" (APB 25) and comply with the pro forma disclosure
requirements of the new standard (see Note 11).
 
    EARNINGS PER SHARE
 
    Earnings per share calculations are in accordance with SFAS No. 128,
"Earnings per Share." "Basic" earnings per share is computed by dividing net
income (loss) by the weighted average number of common shares outstanding for
the year. "Diluted" earnings (loss) per share is computed by dividing net income
(loss) by the total of weighted average number of common shares outstanding plus
the dilutive effect of outstanding stock options and warrants (applying the
treasury stock method). For the years ended December 31, 1996 and 1997, the
effect of stock options and warrants were not included as the results would be
antidilutive.
 
    A reconciliation of the "basic" weighted average number of common shares
outstanding to the "diluted" weighted average number of common shares
outstanding for each of the three years in the period ended December 31, 1998

</TABLE>
 
5.  NOTE RECEIVABLE
 
    The note receivable is from a third party for the purchase of certain
assets. The third party is also a vendor to the Company. The note is secured by
the purchased assets and bears interest at an annual rate of 10 percent. The
original maturity of the note was February 1999. The maturity has been extended
but no specific date has been set. Management believes it will fully realize
this receivable during 1999 through both cash receipts and offsets of purchases
from this vendor.

$6,400,000 based on eligible accounts receivable and inventories. Borrowings
under the line are secured by Company assets, and are also personally guaranteed
by the Company's Chief Executive Officer up to $2.5 million. Borrowings under
the line bear interest at an annual rate of either prime plus .25 percent or
LIBOR plus 2.0 percent. The amended line of credit expires on June 30, 1999.

9. INCOME TAXES
 
    From January 1, 1997 through June 30, 1998, Irwin Naturals had elected
treatment as an S corporation under provisions of the Internal Revenue Code.
Effective June 30, 1998, Irwin Naturals terminated its S corporation election
and became a C corporation. As such, the actual taxes due by Irwin Naturals for
the period from January 1, 1997 to June 30, 1998 are based on S corporation tax
rates, which are substantially less than C corporation tax rates. As a result of
the "pooling of interests" between Irwin Naturals and 4Health, Inc., the
accompanying statements of operations for 1997 and 1998 reflect historical tax
provisions which are a combination of both C corporation and S corporation tax
rates. Because of the Irwin Natural's change in tax status, historical results
of operations, including income taxes and earnings (loss) per share information
may not, in all cases, be comparable to or indicative of current and future
results. Therefore, the statements of operations for 1997 and 1998 also include
unaudited pro forma provisions for income taxes and resulting unaudited pro
forma net income (loss) and unaudited pro forma earnings (loss) per share
information as if Irwin Naturals had been a C corporation during the period from
January 1, 1997 to June 30, 1998.
 
    The Company accounts for income taxes under the provisions of Statement of
Financial Accounting Standards (SFAS) No. 109. Under SFAS No. 109, deferred
income tax assets or liabilities are computed based on the temporary difference
between the financial statement and income tax bases of assets and

liabilities using the current marginal income tax rate. Deferred income tax
expenses or credits are based on the changes in the deferred income tax assets
or liabilities from period to period.
 
    Deferred tax assets may be recognized for temporary differences that will
result in deductible amounts in future periods and for loss carryforwards. A
valuation allowance is recognized if, based on the weight of available evidence,
it is more likely than not that some portion or all of the deferred tax asset
will not be realized. As of December 31, 1997 and 1998, the Company had recorded
valuation allowances.
 
    The components of the deferred income tax assets (liabilities) are as
follows:

13. SUBSEQUENT EVENTS (CONTINUED)
    SALE OF BUILDING
 
    On March 25, 1999, the Company completed the sale of the former 4Health,
Inc. corporate facility. In connection with this sale, the Buyer assumed the
note payable secured by the facility (see Notes 6 and 8).
 
    HEALTH & VITAMIN EXPRESS ACQUISITION
 
    Effective February 15, 1999, the Company, through its newly formed
wholly-owned subsidiary HealthZone.com, purchased the issued and outstanding
shares of Health &Vitamin Express, Inc. (HVE). The purchase price is to be paid
in shares of Company stock and is comprised of several components as follows:
 
    - Initial Shares--363,636 shares issued to Sellers of HVE ($6.25 per share
      at the closing)
 
    - Revenue Shares--Up to 272,727 shares issued to Sellers of HVE based upon
      certain revenue thresholds during first 42 months subsequent to February
      15, 1999
 
    - Profit Shares--Up to 90,909 shares issued to Sellers of HVE based upon
      certain profit thresholds during the first seven years subsequent to
      February 15, 1999
 
    In addition, the Company is obligated to invest or contribute to the
Internet operations a minimum of (A) $4,000,000 during the 18 months subsequent
to February 15, 1999 and (B) $10,000,000 (inclusive of the $4,000,000 provided
in clause (A) above) during the 36 months subsequent to February 15, 1999. If
the Company fails to make the investments or contributions defined above, the
Sellers of HVE will automatically receive the maximum allowable shares subject
to issuance under the provisions of the Revenue and Profit Shares.
 
    INHOLTRA ACQUISITION
 
    Effective March 10, 1999, the Company purchased certain assets and
liabilities of Inholtra Investment Holdings and Trading, N.V., Inholtra, Inc.,
and Inholtra Natural, Ltd. (collectively the Sellers). The purchase price
totaled $13,250,000, of which $3,250,000 was paid in cash. The remaining
$10,000,000 is payable through a promissory note secured by the acquired assets.
The note bears interest at an annual rate of 8 percent and is due in full on
June 10, 1999. The Seller's net assets at the acquisition date were
approximately $2,000,000 (unaudited).
 
    In connection with this acquisition, the Company entered into a consulting
agreement with a former employee of the Sellers. The two year agreement requires
annual consulting fees of $60,000.
 
    The Company is currently seeking to raise additional financing to enable it
to repay the $10,000,000 promissory note above. There can be no assurance that
the Company will be able to secure additional financing at terms acceptable to
the Company, if at all. If the Company is unable to repay the $10,000,000
promissory note, the Company may lose the acquired assets and a portion or all
of the $3,250,000 initial investment.
