                               PROSPECTUS SUMMARY
 
     ZEVEX International, Inc. is the issuer of the shares of Common Stock (the
"Shares") offered in this Prospectus (the "Offering"). Throughout this
Prospectus, ZEVEX International, Inc. and its wholly owned subsidiary, ZEVEX,
Inc., are for convenience collectively referred to as "ZEVEX" or the "Company."
 
                                  THE COMPANY
 
   
     ZEVEX designs and manufactures advanced medical devices, including surgical
systems, device components, and sensors for medical technology companies. The
Company also designs, manufactures, and markets its own medical devices using
its proprietary technologies. The Company's design and manufacturing service
customers are medical technology companies which sell the Company's systems and
devices under private labels or incorporate the Company's devices into their
products. The Company applies its extensive engineering and regulatory
expertise, developed over its 11-year history, to provide its customers with
integrated solutions to the design and manufacture of their medical devices. The
Company has grown steadily, achieving 1996 total revenues of $5,663,733 and net
income of $345,577. Since 1994, the Company's compound annual revenue growth
rate has been approximately 30%. During the first nine months of 1997, the
Company's revenues grew to $6,311,490, approximately a 63% increase over the
comparable period of the prior year. Today, the Company designs and manufactures
over 100 different medical devices for more than 50 different established and
emerging medical technology companies, such as Alaris Medical Systems, Inc.
(formerly IVAC), Allergan, Paradigm Medical Industries, Inc., various divisions
of Baxter Healthcare Corporation, Mentor Corporation, SIMS Deltec, Inc., Staar
Surgical Company, and 3M Company Healthcare.
    
 
   
     The Company's strategy is to augment the continuing growth in its design
and manufacturing service business with the development and commercialization of
proprietary products which utilize the Company's technologies or engineering
expertise or which are complementary to the Company's existing proprietary
products. The Company has successfully applied its engineering and regulatory
expertise to the development, commercialization, and marketing of EnteraLite(R),
the Company's proprietary Ambulatory Enteral Feeding Pump for patients who must
receive direct gastrointestinal nutritional therapy. Historically the Company
has designed and manufactured medical devices utilizing its core competency in
ultrasound technology; however the Company has a wide range of engineering
expertise. The Company's objective is to leverage its engineering and regulatory
expertise to further expand its business as a designer and manufacturer of a
wide variety of customized medical devices for medical technology companies, as
well as a designer, manufacturer, and marketer of a variety of its own
proprietary products. To accomplish this, management intends to do the
following:
    
 
     - Increase the variety of medical devices and systems that the Company
       designs and manufactures for its existing customers
 
     - Expand the number of medical technology companies for which the Company
       provides design and manufacturing services
 
     - Increase sales of the Company's EnteraLite(R) Ambulatory Enteral Feeding
       Pump
 
     - Leverage the Company's design, manufacturing, and regulatory expertise to
       develop new proprietary products
 
     - Acquire other proprietary technologies, products, or manufacturing firms
       similar or complementary to the Company's existing business
 
Management believes that this two-pronged strategy in the $30 billion medical
technology marketplace may allow the Company to benefit from the increasing
demand for design and manufacturing of medical devices and systems, as well as
from the sale of the Company's own proprietary medical devices.
 
     Management of the Company believes that advances in technology, increasing
regulatory complexity and intensified competition will lead many medical
technology companies to expand their out-sourcing of design
 
                                        3
<PAGE>   5
 
and manufacturing services in order to be more efficient. Many emerging medical
technology companies simply do not have the engineering, manufacturing, and
regulatory expertise necessary to quickly and efficiently bring a medical device
from the concept stage to commercial use. Even larger, well-established medical
technology companies, which may have the capital resources to develop such
expertise, may lack the required expertise or the time to accumulate such
expertise in order to meet the market demand for their particular device.
Moreover, in some instances, these medical technology companies may simply elect
not to devote their resources to the design and manufacture of their medical
devices or systems, including obtaining and maintaining the necessary regulatory
approvals and industry certifications for their manufacturing facilities.
Management believes that the Company is well positioned to benefit from this
increasing trend towards out-sourcing. Specifically, the Company may often times
be able to profitably design and manufacture medical devices or systems more
quickly, at a lower cost, and with higher quality than its medical technology
customers are able to achieve.
 
     The Company offers its design and manufacturing customers the following
advantages:
 
     - Broad Experience With Numerous Medical Devices. Over its 11-year history,
       the Company has manufactured numerous advanced medical devices, including
       surgical systems, device components, and sensors.
 
     - Extensive Expertise. As a result of its broad experience, the Company has
       developed extensive expertise in addressing the product design,
       engineering, manufacturing, and regulatory issues associated with a
       variety of medical devices.
 
     - Generally Lower Cost and Higher Quality. The Company provides a wide
       range of engineering services and has the capability to provide complete
       device or system design, including engineering, component analysis,
       testing, and regulatory compliance. The Company strives to increase the
       quality and lower the overall cost of the devices or systems that it
       manufactures for its customers by integrating design and engineering work
       with manufacturing processes, materials acquisitions, quality issues, and
       regulatory considerations.
 
     - Rapid Product Development. The Company believes that, with its
       engineering and manufacturing capabilities, it can develop and
       commercialize new products more rapidly than its customers can, which
       otherwise must expend significant time and financial resources to develop
       internal engineering expertise and qualified manufacturing facilities.
 
     - Regulatory Compliance. The Company is ISO 9001 and EN 46001 certified,
       and the Company has developed internal systems intended to maintain
       compliance with the FDA's GMP requirements. The Company devotes
       significant management time and financial resources to GMP compliance and
       ISO certification. By using the Company's manufacturing services,
       customers relieve themselves of many stringent regulatory and industry
       certification requirements.
 
     - Production Flexibility. The Company's broad customer base permits it to
       offer its customers production flexibility, which enables customers to
       implement product enhancements and to adjust production volumes in
       response to fluctuations in market demand.
 
     The Company is located at 4314 ZEVEX Park Lane, Salt Lake City, Utah 84123.
The Company's telephone number is (801) 264-1001. The Company is currently
incorporated in the State of Nevada, although the Company intends to
reincorporate in Delaware in the near future. ZEVEX International, Inc.,
conducts all its operations through its wholly owned subsidiary, ZEVEX, Inc.
ZEVEX, Inc. is currently incorporated in the State of Utah, although the Company
intends also to cause ZEVEX, Inc. to be reincorporated in Delaware in the near
future.

                                  RISK FACTORS
 
     Prospective purchasers of the Shares should consider carefully the risk
factors set forth below, in addition to the other information contained in this
Prospectus, before making a decision to purchase the Shares. This Prospectus
contains, in addition to historical information, forward-looking statements that
involve risks and uncertainties. The Company's actual results may differ
materially from the results discussed in the forward-looking statements as a
result of certain factors, including those set forth in the following "Risk
Factors" and elsewhere in this Prospectus. In each instance in which a risk
factor identifies an event that would or could adversely affect the Company,
such risk should be viewed as potentially adversely affecting the Company's
business, results of operations, and financial position.
 
DEPENDENCE ON MAJOR CUSTOMERS
 
   
     The Company's revenues historically have been, and for a substantial period
of time in the future likely will be, largely derived from the sale of its
design and manufacturing services to a small number of major customers. During
the 1993, 1994, and 1995 fiscal years, the Company had two major customers,
Allergan and Alaris Medical Systems, Inc. (formerly IVAC Corporation), who
together accounted for more than 50% of the Company's sales. In 1996, these two
customers plus a third customer, Paradigm Medical Inc., accounted for
approximately 66% of sales. These three customers each accounted for more than
ten percent of the Company's total sales in 1996. During the first nine months
of the 1997 fiscal year, 14% of sales were from Allergan, 21% of sales were from
Paradigm, 20% of sales were from Alaris, and 12% of sales were from Mentor
Corporation. No assurances can be given that such customers will continue to do
business with the Company or that the volume of their orders for the Company's
devices will increase or remain constant. The loss of any of such major
customers, or a significant reduction in the volume of their orders for the
Company's devices, will have a material adverse impact on the Company's
operations. In addition, if one or more of these customers were to seek and
obtain price discounts from the Company for the Company's devices, the resulting
lower gross margins on those devices would have a material adverse effect on the
Company's overall results of operations. If any customer with which the Company
does a substantial amount of business were to encounter financial distress, the
customer's lateness, unwillingness, or inability to pay its obligations to the
Company could result in a material adverse effect on the Company's results of
operations and financial condition. See "BUSINESS -- Significant Customers for
Which ZEVEX Provides Design and Manufacturing Services."
    
 
RISK FACTORS RELATING TO THE COMPANY'S CUSTOMERS
 
     At the present time, and for a substantial period of time in the future,
the Company's success will depend largely on the success of the customers for
its manufacturing services and on the medical devices designed and manufactured
by the Company for those customers. Any unfavorable developments or adverse
effects on the sales of those devices or such customers' businesses, results of
operations, or financial position could have a corresponding adverse effect on
the Company. In addition, the Company sells certain types of medical devices to
multiple customers and to the extent there is an unfavorable development
affecting the sales of any such type of device generally, the adverse effect of
such development on the Company would be more substantial than that presented by
the decline in sales to a single customer for such type of device. The Company
believes that its design and manufacturing customers and their devices (and the
Company indirectly) are generally subject to the following risks:
 
     Competitive Environment. The medical products industry is highly
competitive and subject to significant technological change. Participation in
the industry requires ongoing investment to keep pace with technological
developments and quality and regulatory requirements. The medical products
industry consists of numerous companies, ranging from start-up to
well-established companies. Many of the Company's customers have a limited
number of products, and some market only a single product. As a result, any
adverse development with respect to these customers' products may have a
material adverse effect on the business and financial condition of such
customer, which may adversely affect that customer's ability to purchase and pay
for its products manufactured by the Company. The competitors and potential
competitors of the Company's customers may succeed in developing or marketing
technologies and products that will be preferred in the marketplace over the
devices manufactured by the Company for its customers or that would render its
 
                                        7
<PAGE>   9
 
   
customers' technology and products obsolete or noncompetitive. In addition,
other competitors may develop alternative treatments or cures so that the need
for the products manufactured by the Company could be reduced or eliminated. See
"BUSINESS -- Overview of Medical Technology Industry."
    
 
     Emerging Technology Companies. A significant number of the Company's
customers are emerging medical technology companies that have competitors and
potential competitors with substantially greater capital resources, research and
development staffs, and facilities, and substantially greater experience in
developing new products, obtaining regulatory approvals, and manufacturing and
marketing medical products. Approximately five customers, representing 15% of
the Company's revenues in fiscal year 1996, were, in management's opinion,
emerging medical technology companies. These customers may not be successful in
launching and marketing their products, or may not respond to pricing,
marketing, or other competitive pressures or the rapid technological innovation
demanded by the marketplace and, as a result, may experience a significant drop
in product revenues which would have a material adverse effect on the Company's
business, results of operations, and financial condition. See
"BUSINESS -- Overview of Medical Technology Industry."
 
     Customer Regulatory Compliance. The Food and Drug Administration (the
"FDA") regulates many of the devices manufactured by the Company under the
Federal Food, Drug and Cosmetic Act, as amended (the "FDC Act"), which requires
certain clearances from the FDA before new medical products can be marketed. As
a prerequisite to any introduction of a new device into the medical marketplace,
the Company's customers must obtain necessary product clearances from the FDA or
other regulatory agencies with applicable jurisdiction. There can be no
assurance that the Company's customers will obtain such clearances on a timely
basis, if at all.
 
   
     Certain medical devices manufactured by the Company may be subject to the
need to obtain FDA clearance of an application for premarket approval ("PMA"),
which requires substantial preclinical and clinical testing and may cause delays
and prevent introduction of such devices. Currently, at least two of the
Company's customers are seeking or plan to seek such PMA clearances for devices
to be manufactured by the Company. Other devices can be marketed without a PMA,
but only by establishing in a 510(k) premarket notification "substantial
equivalence" to a predicate device. FDA clearance to market regulations depend
heavily on administrative interpretations, which may change retroactively and
may create additional barriers that prevent or delay the introduction of a
product. The process of obtaining a PMA or a 510(k) clearance could delay the
introduction of a product. A PMA for a product could be denied altogether if
clinical testing does not establish that the product is safe and effective. A
510(k) premarket notification may also need to contain clinical data. Clinical
testing must be performed in accordance with the FDA's regulations. A customer's
failure to comply with the FDA's requirements can result in the delay or denial
of its PMA. Delays in obtaining a PMA are frequent and could result in delaying
or canceling customer orders to the Company. Many products never receive a PMA.
Similarly, 510(k) clearance may be delayed, and in some instances, 510(k)
clearance is never obtained.
    
 
     Once a product is in commercial distribution, discovery of product problems
or failure to comply with regulatory standards may result in restrictions on the
product's future use or withdrawal of the product from the market despite prior
governmental clearance. Additionally, once FDA clearance is obtained, a new
clearance in the form of a PMA supplement may be needed to modify the device,
its intended use, or its manufacturing. There can be no assurance that product
recalls, product defects, or modification or loss of necessary regulatory
clearance will not occur in the future. The delays and potential product
cancellations inherent in the development, regulatory clearance,
commercialization, and ongoing regulatory compliance of products manufactured by
the Company for its customers may have a material adverse effect on the
Company's business, reputation, results of operations, and financial condition.
 
     Sales of the Company's medical products outside the United States are
subject to regulatory requirements that vary widely from country to country. The
time required to obtain clearance for sale in foreign countries may be longer or
shorter than that required for FDA clearance, and the requirements may differ.
The FDA also regulates the sale of exported medical devices, although to a
lesser extent than devices sold in the United States. For medical products
exported to countries in Europe, the Company anticipates that its
 
                                        8
<PAGE>   10
 
customers will want their products to qualify for distribution under the "CE
Mark." The CE Mark is a designation given to products which comply with certain
European Economic Area policy directives and therefore may be freely traded in
almost every European country. Commencing in 1998, medical product manufacturers
will be required to obtain certifications necessary to enable the CE Mark to be
affixed to medical products they manufacture for sale throughout the European
Community. In addition, the Company's customers must comply with other laws
generally applicable to foreign trade, including technology export restrictions,
tariffs, and other regulatory barriers. There can be no assurance that the
Company's customers will obtain all required clearances or approvals for
exported products on a timely basis, if at all. Failure or delay by the
Company's customers in obtaining the requisite regulatory approvals for exported
instruments manufactured by the Company may have a material adverse effect on
the Company's business, results of operations, and financial condition.
 
     Medical devices manufactured by the Company and marketed by its customers
pursuant to FDA or foreign clearances or approvals are subject to pervasive and
continuing regulation by the FDA and certain state and foreign regulatory
agencies. Regulatory requirements may include significant limitations on the
indicated uses for which the product may be marketed. FDA enforcement policy
prohibits the marketing of approved medical products for unapproved uses. The
Company's customers control the marketing of their products, including
representing to the market the approved uses of their products. If a customer
engages in prohibited marketing practices, the FDA or another regulatory agency
with applicable jurisdiction could intervene, possibly resulting in marketing
restrictions, including prohibitions on further product sales, or civil or
criminal penalties, which could have a material adverse effect on the Company's
business, the results of operations, and financial condition.
 
     Changes in existing laws and regulations or policies could affect adversely
the ability of the Company's customers to comply with regulatory requirements.
Failure to comply with regulatory requirements could have a material adverse
effect on the customer's business, results of operations, and financial
condition, which, in turn, could affect adversely the Company's business,
results of operations, and financial condition. There can be no assurance that a
customer of the Company, or the Company, will not be required to incur
significant costs to comply with laws and regulations in the future, or that
such customer or the Company will be able to comply with such laws and
regulations, or that compliance with such laws and regulations will not have a
material adverse effect on the Company's business, results of operations, and
financial condition. See "BUSINESS--Governmental Regulation Within the United
States" and "-- Governmental Regulations Outside the United States."
 
     Uncertain Market Acceptance of Products. There can be no assurance that the
products created for the Company's customers will gain any significant market
acceptance and market share among physicians and other health care providers,
patients, or health care payors, even if required regulatory approvals are
obtained. Market acceptance may depend on a variety of factors, including
educating health care providers regarding the use of a new product or procedure,
overcoming objections to certain effects of the product or its related treatment
regimen, and convincing health care payors that the benefits of the product and
its related treatment regimen outweigh its costs. Market acceptance and market
share are also affected by the timing of market introduction of competitive
products. Accordingly, the relative speed with which the Company's customers can
develop products, gain regulatory approval and reimbursement acceptance, and
supply commercial quantities of the product to the market are expected to be
important factors in market acceptance and market share. Some of the Company's
customers, especially emerging medical technology companies, have limited or no
experience in marketing their products and have not made marketing or
distribution arrangements for their products. The Company's customers may be
unable to establish effective sales, marketing, and distribution channels to
successfully commercialize their products. The failure by the Company's
customers to gain market acceptance of their products could have a material
adverse effect on the Company's business, results of operations, and financial
conditions.
 
     Product Obsolescence. The marketplace for medical products is characterized
by rapid change and technological innovation. As a result, the Company and its
customers are subject to the risk of product obsolescence, whether from
prolonged development or government approval cycles or the development of
improved products or processes by competitors. In addition, the marketplace
could conclude that the task for
 
                                        9
<PAGE>   11
 
which a customer's product was designed is no longer an element of a generally
accepted diagnostic or treatment regimen. Any development adversely affecting
the market for a product manufactured by the Company would result in the
Company's having to reduce production volumes or to discontinue manufacturing
the product, which could have a material adverse effect on the Company's
business, results of operations, and financial condition. See
"BUSINESS -- Overview of Medical Technology Industry."
 
   
     Customers' Future Capital Requirements. Certain of the Company's customers,
especially the emerging medical technology companies, are not profitable and may
have little or no revenues, but they have significant working capital
requirements. Such customers may be required to raise additional funds through
public or private financings, including equity financings. Adequate funds for
their operations may not be available when needed, if at all. Insufficient funds
may require a customer to delay development of a product, clinical trials (if
required), or the commercial introduction of the product or prevent such
commercial introduction altogether. Depending on the significance of a
customer's product to the Company's revenues or profitability, any adverse
effect on a customer resulting from insufficient funding could result in a
material adverse effect on the Company's business, results of operations, and
financial condition.
    
 
     Uncertainty of Third-Party Reimbursement. Sales of many of the devices
manufactured by the Company will be dependent in part on availability of
adequate reimbursement for those instruments from third-party health care
payors, such as government and private insurance plans, health maintenance
organizations, and preferred provider organizations. Third-party payors are
increasingly challenging the pricing of medical products and services. There can
be no assurance that adequate levels of reimbursement will be available to
enable the Company's customers to achieve market acceptance of their products.
Without adequate support from third-party payors, the market for the products of
the Company's customers may be limited.
 
     Nonmedical Customers. While the Company presently does not have any
significant nonmedical customers, the Company may in the future perform
significant design and manufacturing work for such parties. Nonmedical customers
are subject to general business risks, such as competition, market acceptance of
their products, capital requirements, and credit risks. The Company's future
nonmedical customers may operate in highly competitive industries in which their
products compete on price, quality, and product enhancements and are subject to
risks of technological obsolescence. As a result, sales to nonmedical customers
may be volatile and subject to risks of cancellation. Any unfavorable
development experienced by such future nonmedical customers, whether of a
general nature or a specific risk not anticipated by the Company, could have a
material adverse effect on the Company's business, results of operations, and
financial condition.
 
UNCERTAINTY OF MARKET ACCEPTANCE OF OUT-SOURCING MANUFACTURING OF MEDICAL
INSTRUMENTS
 
     The Company believes that the market for out-sourcing the design and
manufacture of advanced medical products for medical technology companies is in
its early stages. Many of the Company's potential customers have internal design
and manufacturing facilities. The Company's engineering and manufacturing
activities require that customers provide the Company with access to their
proprietary technology and relinquish the control associated with internal
engineering and manufacturing. As a result, potential customers may decide that
the risks of out-sourcing engineering or manufacturing are too great or exceed
the anticipated benefits of out-sourcing. In addition, medical technology
companies that have previously made substantial investments to establish design
and manufacturing capabilities may be reluctant to out-source those functions.
If the medical technology industry generally, or any significant existing or
potential customer, concludes that the disadvantages of out-sourcing
manufacturing outweigh the advantages, the Company could suffer a substantial
reduction in the size of one or more of its current target markets, which could
have a material adverse effect on its business, results of operations, and
financial condition.
 
COMPETITION IN OUT-SOURCING MANUFACTURING OF MEDICAL INSTRUMENTS
 
     The Company faces competition from design firms and other manufacturers
that operate in the medical technology industry. Many competitors have
substantially greater financial, research, and development
 
                                       10
<PAGE>   12
 
resources than the Company. Also, manufacturers focusing in other industries may
decide to enter into the medical technology industry. Competition from any of
the foregoing sources could place pressure on the Company to accept lower
margins on its contracts or lose existing or potential business, which could
result in a material adverse effect on the Company's business, results of
operations, and financial condition. To remain competitive, the Company must
continue to provide and develop technologically advanced manufacturing services,
maintain quality levels, offer flexible delivery schedules, deliver finished
products on a reliable basis, and compete favorably on the basis of price. There
can be no assurance that the Company will be able to compete favorably with
respect to these factors. See "BUSINESS -- Competition for ZEVEX's Design and
Manufacturing Services."
 
EARLY TERMINATION OF AGREEMENTS
 
   
     The Company's agreements with major customers generally permit the
termination of the agreements before expiration thereof if certain events occur
that are materially adverse to the design, development, manufacture or sale of
the product. Examples of such events include the failure to obtain or the
withdrawal of regulatory clearance, or an alteration of regulatory clearance
that is materially adverse to the customer or which prohibits or interferes with
the manufacture or sale of the products. The performance of agreements with
major customers may be suspended or excused if certain conditions, generally
beyond the control of the customer or the Company (so-called force majeure
events), cause the failure or delay of performance. Such early termination could
have a material adverse affect on the Company's business, results of operations,
and financial condition, including in certain instances the transfer of
manufacturing know-how to the customer.
    
 
RISK FACTORS IN MARKETING THE COMPANY'S PROPRIETARY PRODUCTS
 
     In producing and marketing its own proprietary devices, the Company faces
many of the same risks that its design/manufacturing customers face. As
discussed above with respect to its customers, such risks include:
 
     - The medical products industry is highly competitive. A significant number
       of the Company's competitors have substantially greater capital
       resources, research and development staffs, and facilities, and
       substantially greater experience in developing new products, obtaining
       regulatory approvals, and manufacturing and marketing medical products.
       Competitors may succeed in marketing products preferable to the Company's
       products or rendering the Company's products obsolete.
 
     - The medical products industry is subject to significant technological
       change and requires ongoing investment to keep pace with technological
       development, quality, and regulatory requirements. In order to compete in
       this marketplace, the Company will be required to make ongoing investment
       in research and development with respect to its existing and future
       products.
 
     - The Company is subject to substantial risks involved in developing and
       marketing products regulated by the FDA and comparable foreign agencies.
       There can be no assurance that the Company will obtain the necessary FDA
       or foreign clearances on a timely basis, if at all. As discussed above,
       commercialized medical products are subject to further regulatory
       restrictions which may adversely affect the Company. Changes in existing
       laws and regulations or policies could affect adversely the ability of
       the Company to comply with regulatory requirements. The delays and
       potential product cancellations inherent in obtaining regulatory approval
       and maintaining regulatory compliance of products manufactured by the
       Company may have a material adverse effect on the Company's business,
       reputation, results of operations, and financial condition.
 
     - There can be no assurance that the Company's products will gain any
       significant market acceptance among physicians and other health care
       providers, patients, or health care payors, even if required regulatory
       approvals are obtained.
 
     - Revenues for many of the devices manufactured by the Company may be
       dependent in part on availability of adequate reimbursement for those
       devices from third-party health care payors, such as government and
       private insurance plans. There is no assurance that the levels of
       reimbursements
 
                                       11
<PAGE>   13
 
       offered by third-party payors will be sufficient to achieve market
       acceptance of the Company's products.
 
     The Company may not be successful in launching and marketing its own
proprietary devices, or may not respond to pricing, marketing, or other
competitive pressures or the rapid technological innovation demanded by the
marketplace and, as a result, may experience a significant drop in its product
revenues, which could have a material adverse effect on the Company's business,
results of operations, and financial condition. See "BUSINESS -- Overview of
Medical Technology Industry."
 
REGULATORY COMPLIANCE FOR MANUFACTURING FACILITIES
 
     Applicable law requires that the Company comply with the FDA's detailed
good manufacturing practices ("GMP") regulations for the manufacture of medical
devices. The FDA monitors compliance with its GMP regulations by subjecting
medical product manufacturers to periodic FDA inspections of their manufacturing
facilities. To ensure compliance with GMP requirements, the Company expends
significant time, resources, and effort in the areas of training, production,
and quality assurance. In addition, the FDA typically inspects a manufacturer of
a PMA device before approving a PMA. The failure to pass such an inspection
could result in delay in approving a PMA. The Company is also subject to other
regulatory requirements and may need to submit reports to the FDA relating to
certain types of adverse events. Failure to comply with GMP regulations or other
applicable legal requirements can lead to warning letters, seizure of violative
products, injunctive actions brought by the U.S. government, and potential civil
or criminal liability on the part of the Company and of the officers and
employees who are responsible for the activities that lead to any violation. In
addition, the continued sale of any instruments manufactured by the Company may
be halted or otherwise restricted. Any such actions could have a material
adverse effect on the willingness of customers and prospective customers to do
business with the Company. In order for the Company's instruments to be exported
and for the Company and its customers to be qualified to use the CE Mark for
sales into the European Economic Area, the Company maintains International
Organization for Standardization ("ISO") 9001/EN 46001 certification, which
subjects the Company's operations to periodic surveillance audits. The ultimate
regulatory risks present in manufacturing products for markets governed by these
standards are currently substantially similar to those posed by GMP regulations.
There can be no assurance that the Company's manufacturing operations will be
found to comply with GMP regulations, ISO standards, or other applicable legal
requirements or that the Company will not be required to incur substantial costs
to maintain its compliance with existing or future manufacturing regulations,
standards, or other requirements. Any such noncompliance or increased cost of
compliance could have a material adverse effect on the Company's business,
results of operations, and financial condition.
 
     The Company is also subject to numerous federal, state, and local laws
relating to such matters as safe working conditions, manufacturing practices,
environmental protection, fire hazard control, and disposal of hazardous or
potentially hazardous substances. While the Company has not been the subject of
any material proceeding concerning such laws, and believes it is currently in
compliance with such laws in all material respects, there can be no assurance
that the Company will not be required to incur significant costs to comply with
such laws and regulations now or in the future, or that such laws or regulations
will not have a material adverse effect upon the Company's ability to do
business. Changes in existing requirements or adoption of new requirements or
policies could affect adversely the ability of the Company to comply with
regulatory requirements. Failure to comply with regulatory requirements could
have a material adverse effect on the Company's business, results of operations,
and financial condition. See "BUSINESS -- Governmental Regulation Within the
United States" and "-- Governmental Regulations Outside the United States."
 
PRODUCT DEVELOPMENT
 
   
     The success of the Company will depend to a significant extent upon its
ability to enhance and expand on its current offering of proprietary products
and to develop and introduce additional innovative products that gain market
acceptance. While the Company maintains research and development programs and
has established a Technical Advisory Board to assist it, there is no assurance
that the Company will be successful in selecting, developing, manufacturing, and
marketing new products or enhancing its existing products on a
    
 
                                       12
<PAGE>   14
 
timely or cost-effective basis. Moreover, the Company may encounter technical
problems in connection with its efforts to develop or introduce new products or
product enhancements. Some of the devices currently under consideration by the
Company (as well as devices of some of its customers) will require significant
additional development, pre-clinical testing and clinical trials and related
investment prior to their commercialization. There can be no assurance that such
devices will be successfully developed, prove to be safe or efficacious in
clinical trials, meet applicable regulatory standards, be capable of being
produced in commercial quantities at reasonable costs, or be successfully
marketed. The failure of the Company to develop or introduce new products or
product enhancements that achieve market acceptance on a timely basis could have
a material adverse effect on the Company's business, results of operations, and
financial condition.
 
DESIGN AND MANUFACTURING PROCESS RISKS
 
     While the Company has substantial experience in designing and manufacturing
devices, the Company may still experience technical difficulties and delays with
the design and manufacturing of its or its customer's products. Such
difficulties could cause significant delays in the Company's production of
products and have a material adverse effect on the Company's revenues. In some
instances, payment by a manufacturing customer is dependent on the Company's
ability to meet certain design and production milestones in a timely manner.
Also, some major contracts can be cancelled if purchase orders thereunder are
not completed when due. Potential difficulties in the design and manufacturing
process that could be experienced by the Company include difficulty in meeting
required specifications, difficulty in achieving necessary manufacturing
efficiencies, and difficulties in obtaining materials on a timely basis. Such
design and manufacturing difficulties could have a material adverse effect on
the Company's business, results of operations, and financial condition.
 
EXPANSION OF MARKETING ACTIVITIES; LIMITED DISTRIBUTION
 
     The Company currently has a limited domestic direct sales force consisting
of eight individuals, complemented by a network of independent manufacturing
representatives. The Company anticipates that it will need to increase its
marketing and sales capability significantly to more fully cover its target
markets, particularly as additional proprietary devices become commercially
available. There can be no assurance that the Company will be able to compete
effectively in attracting and retaining qualified sales personnel or independent
manufacturing representatives as needed. There can be no assurance that the
Company or its independent manufacturing representatives will be successful in
marketing or selling the Company's services and products. The Company's ability
to sell its devices in certain areas may depend on alliances with independent
manufacturing representatives. There can be no assurance that the Company will
be able to identify and obtain suitable independent manufacturing
representatives in desirable markets.
 
PRODUCT RECALLS
 
     If a device that is designed or manufactured by the Company is found to be
defective, whether due to design or manufacturing defects, to improper use of
the product, or to other reasons, the device may need to be recalled, possibly
at the Company's expense. Furthermore, the adverse effect of a product recall on
the Company might not be limited to the cost of a recall. For example, a product
recall could cause a general investigation of the Company by applicable
regulatory authorities as well as cause other customers to review and
potentially terminate their relationships with the Company. Recalls, especially
if accompanied by unfavorable publicity or termination of customer contracts,
could result in substantial costs, loss of revenues, and a diminution of the
Company's reputation, each of which would have a material adverse effect on the
Company's business, results of operations, and financial condition.
 
RISK OF PRODUCT LIABILITY
 
   
     The manufacture and sale of products, and especially medical products,
entails an inherent risk of product liability. The Company does maintain product
liability insurance with limits of $1 million per occurrence and $2 million in
the aggregate. There can be no assurance that such insurance is adequate to
cover potential claims or that the Company will be able to obtain product
liability insurance on acceptable terms in the future, or that any product
liability insurance subsequently obtained will provide adequate
    
 
                                       13
<PAGE>   15
 
coverage against all potential claims. Such claims may be large in the medical
products area where product failure may result in loss of life or injury to
persons. A successful claim brought against the Company in excess of its
insurance coverage, or any material claim for which insurance coverage was
denied or limited, could have material adverse effect on the Company's business,
results of operations, and financial condition. Additionally, the Company
generally provides a design defect warranty and in some instances indemnifies
its customers for failure to conform to design specifications and against
defects in materials and workmanship. Any substantial claim against the Company
under such warranties or indemnification could have a material adverse effect on
the Company's business, results of operations, and financial condition.
 
POTENTIAL INABILITY TO SUSTAIN AND MANAGE GROWTH
 
     The Company's need to manage its growth effectively will require it to
continue to implement and improve its operational, financial, and management
information systems, to develop its managers' and project engineers' management
skills, and to train, motivate, and manage its employees. The Company must also
be able to attract and retain a sufficient number of suitable employees to
sustain its growth. If the Company cannot keep pace with the growth of its
customers, it may lose customers and its growth may be limited.
 
DEPENDENCE UPON MANAGEMENT
 
   
     The Company is substantially dependent upon its key managerial, technical,
and engineering personnel, particularly its three executive officers, Dean G.
Constantine, Chief Executive Officer and President, David J. McNally, Vice
President and Marketing Director, and Phillip L. McStotts, Chief Financial
Officer and Secretary/Treasurer. The Company must also attract and retain highly
qualified engineering, technical, and managerial personnel. Competition for such
personnel is intense, the available pool of qualified candidates is limited, and
there can be no assurance that the Company can attract and retain such
personnel. The loss of its key personnel could have a material adverse effect on
the Company's business, results of operations, and financial condition. None of
the Company's key personnel have an employment agreement with the Company. See
"MANAGEMENT." The Company carries key-man life insurance on the lives of its
Chief Executive Officer, Chief Financial Officer, and Vice President in the
amount of $500,000 each. No assurances can be given that such insurance would
provide adequate compensation to the Company in the event of the death of such
key employee.
    
 
PATENT PROTECTION
 
   
     As of September 30, 1997, the Company held three U.S. patents and had
applied for seven additional U.S. patents on devices developed by the Company.
The Company has received Notices of Allowance from the U.S. Patent and Trademark
office with respect to four of these seven applications. There is no assurance
that the patent applications will issue. Such patents disclose certain aspects
of the Company's technologies and there can be no assurance that others will not
design around the patent and develop similar technology. The Company believes
that its devices and other proprietary rights do not infringe any proprietary
rights of third parties. There can be no assurance, however, that third parties
will not assert infringement claims in the future.
    
 
CONTROL BY MANAGEMENT AND CERTAIN MAJOR SHAREHOLDERS
 
     Following this Offering, the current executive officers and directors of
the Company, together with those persons who are the beneficial owners of more
than 5% of the Company's Common Stock, will beneficially own or have voting
control over approximately 31% of the outstanding Common Stock (approximately
29% if the Underwriters' over-allotment option is exercised in full).
Accordingly, these individuals will have the ability to influence the election
of the Company's directors and most corporate actions. This concentration of
ownership, together with other provisions in the Company's charter and
applicable corporate law, may also have the effect of delaying, deterring, or
preventing a change in control of the Company. See "PRINCIPAL AND SELLING
SHAREHOLDERS."
 
                                       14
<PAGE>   16
 
SUPPLIERS AND SHORTAGES OF COMPONENT PARTS
 
     The Company relies on third-party suppliers for each of the component parts
used in manufacturing its customers' devices. Although component parts are
generally available from multiple suppliers, certain component parts may require
long lead times, and the Company may have to delay the manufacture of customer
devices from time to time due to the unavailability of certain component parts.
In addition, even if component parts are available from an alternative supplier,
the Company could experience additional delays in obtaining component parts if
the supplier has not met the Company's vendor qualifications. Component
shortages for a particular device may adversely affect the Company's ability to
satisfy customer orders for that device. Such shortages and extensions of
production schedules may delay the recognition of revenue by the Company and may
in some cases constitute a breach of a customer contract, which may have a
material adverse effect on the Company's business, results of operations, and
financial condition. If shortages of component parts continue or if additional
shortages should occur, the Company may be forced to pay higher prices for
affected components or delay manufacturing and shipping particular devices,
either of which could adversely affect subsequent customer demand for such
devices and the Company's business, results of operations, and financial
condition.
 
CUSTOMER CONFLICTS
 
     The medical technology industry reflects vigorous competition among its
participants. As a result, its customers sometimes require the Company to enter
into noncompetition agreements that prevent the Company from manufacturing
instruments for its customers' competitors. For example, the Company has agreed
with one customer not to manufacture certain devices for laser cataract surgery
for any other customer or potential customer. Such restrictions generally apply
during the term of the customer's manufacturing contract and, in some instances,
for a period following termination of the contract. If the Company enters into a
noncompetition agreement, the Company may be adversely affected if its
customer's product is not successful and the Company must forgo an opportunity
to manufacture a successful instrument for such customer's competitor. Any
conflicts among its customers could prevent or deter the Company from obtaining
contracts to manufacture successful instruments, which could result in a
material adverse effect on its business, results of operations and financial
condition.
 
FUTURE CAPITAL REQUIREMENTS
 
   
     The Company believes that the net proceeds of this offering, together with
existing capital resources and amounts available under the Company's existing
bank line of credit, will satisfy the Company's anticipated capital needs for
the next three years (depending primarily on the Company's growth rate and its
results of operations). The commercialization of proprietary products, which is
an element of the Company's growth strategy, would require increased investment
in working capital and could therefore shorten this period. Thereafter, the
Company may be required to raise additional capital or increase its borrowing
capacity, or both. There can be no assurance that alternative sources of equity
or debt will be available in the future or, if available, will be on terms
acceptance to the Company. Any additional equity financing would result in
additional dilution to the Company's shareholders, including shareholders who
purchase Common Stock in this Offering. If adequate funds are not available, the
Company's business, results of operations, and financial condition could be
materially adversely affected. See "MANAGEMENT'S DISCUSSION AND ANALYSIS OF
FINANCIAL CONDITION AND RESULTS OF OPERATIONS."
    
 
RELIANCE ON EFFICIENCY OF DISTRIBUTION AND THIRD PARTIES
 
     The Company believes its financial performance is dependent in part on its
ability to provide prompt, accurate, and complete services to its customers on a
timely and competitive basis. Accordingly, delays in distribution in its
day-to-day operations or material increases in its costs of procuring and
delivering products could have an adverse effect on the Company's results of
operations. Any failure of either its computer operating system or its telephone
system could adversely affect its ability to receive and process customer's
orders and ship products on a timely basis. Strikes or other service
interruptions affecting Federal Express Corporation, United Parcel Service of
America, Inc., or other common carriers used by the Company to
 
                                       15
<PAGE>   17
 
receive necessary components or other materials or to ship its products also
could impair the Company's ability to deliver products on a timely and
cost-effective basis.
 
VOLATILITY OF REVENUES AND PRODUCT MIX
 
     The Company's annual and quarterly operating results are affected by a
number of factors, including the volume and timing of customer orders, which
vary due to (i) variation in demand for the customer's products as a result of,
among other things, product life cycles, competitive conditions, and general
economic conditions, (ii) the customer's attempt to balance its inventory, (iii)
the customer's need to adapt to changing regulatory conditions and requirements,
and (iv) changes in the customer's manufacturing strategy. Such results may also
be affected by technical difficulties and delays in the design and manufacturing
processes. The foregoing factors may cause fluctuations in revenues and
variations in product mix which could in turn cause fluctuations in the
Company's gross margin. Under the terms of the Company's contracts with many of
its customers, the customers have broad discretion to control the volume and
timing of product deliveries. Further, the Company's contracts with its
customers typically have no minimum purchase requirements. As a result,
production may be reduced or discontinued at any time. Therefore, it is
difficult for the Company to forecast the level of customer orders with
certainty, making it difficult to schedule production and maximize manufacturing
capacity. Other factors that may adversely affect the Company's annual and
quarterly results of operations include inexperience in manufacturing a
particular instrument, inventory shortages or obsolescence, labor costs or
shortages, low gross margins on design projects, an increase in design revenues
as a percentage of total revenues, price competition, and regulatory
requirements. Because the Company's business organization and its related cost
structure anticipate supporting a certain minimum level of revenues, the
Company's limited ability to adjust its short term cost structure would compound
the adverse effect of any significant revenue reduction. Any one of these
factors or a combination thereof could result in a material adverse effect on
the Company's business, results of operations, and financial condition.
 
UNCERTAIN PROTECTION OF INTELLECTUAL PROPERTY
 
     To maintain the secrecy of its proprietary information, the Company relies
on a combination of trade secret laws and internal security procedures. The
Company typically requires its employees, consultants, and advisors to execute
confidentiality and assignment of inventions agreements. There can be no
assurance, however, that the common law, statutory, and contractual rights on
which the Company relies to protect its intellectual property and confidential
and proprietary information will provide it with adequate or meaningful
protection. Third parties may independently develop products, techniques, or
information which are substantially equivalent to the products, techniques, or
information that the Company considers proprietary. In addition, proprietary
information regarding the Company could be disclosed in a manner against which
the Company has no meaningful remedy. Disputes regarding the Company's
intellectual property could force the Company into expensive and protracted
litigation or costly agreements with third parties. An adverse determination in
a judicial or administrative proceeding or failure to reach an agreement with a
third party regarding intellectual property rights could prevent the Company
from manufacturing and selling certain of its products. Any of the foregoing
circumstances could have a material adverse effect on the Company's business,
results of operations, or financial condition.
 
LIMITED MARKET FOR COMMON STOCK
 
     Historically, the market for the Common Stock has been limited due to the
relatively low trading volume and the small number of brokerage firms acting as
market makers. In May 1997, the Company's Common Stock was listed for trading on
the American Stock Exchange, which may increase the market for the Common Stock.
No assurance can be given, however, that the market for the Common Stock will
continue or increase, or that the prices in such market will be maintained at
their present levels.
 
POSSIBLE VOLATILITY OF STOCK PRICE
 
     Announcements of technological innovations for new commercial devices by
the Company or its competitors, developments concerning the Company's
proprietary rights, or the public concern as to safety of
 
                                       16
<PAGE>   18
 
its devices may have a material adverse impact on the Company's business and on
the market price of the Common Stock, particularly as the Company expands its
efforts to become a medical technology company that manufactures and markets its
own proprietary devices. The market price of the Common Stock may be volatile
and may fluctuate based on a number of factors, including significant
announcements by the Company and its competitors, quarterly fluctuations in the
Company's operating results, and general economic conditions and conditions in
the medical technology industry. In addition, in recent years the stock market
has experienced extreme price and volume fluctuations, which have had a
substantial effect on the market prices for many medical-technology companies
and are often unrelated to the operating performance of such companies.
 
ISSUANCE OF ADDITIONAL SHARES FOR ACQUISITION OR EXPANSION
 
   
     Any future major acquisition or expansion of the Company may result in the
issuance of additional common shares or other stocks or instruments which may be
authorized without shareholder approval. The issuance of subsequent securities
may also result in substantial dilution in the percentage of the Common Stock
held by existing shareholders at the time of any such transaction. Moreover, the
shares or warrants issued in connection with any such transaction may be valued
by the Company's management based on factors other than the trading price on the
exchange.
    
 
DIVIDENDS
 
     While the Company has declared one stock dividend in its history, it has
never paid a cash dividend and there can be no assurance that the Company will
pay a dividend on Common Stock in the future. Any future cash dividends will
depend on earnings, if any, the Company's financial requirements, and other
factors. The Company's management does not currently intend to pay any cash
dividends in the foreseeable future. Investors who anticipate the need of an
immediate income from their investment in the Common Stock should refrain from
the purchase of the Common Stock being offered hereby. Additionally, the Company
is restricted from declaring any cash dividends under its current line of credit
arrangement.
 
POSSIBLE RULE 144 SALES
 
     The shares of Common Stock presently owned by management and certain other
shareholders are deemed to be "restricted securities" as such term is defined in
Rule 144 under the Securities Act of 1933, as amended. Rule 144 provides that a
person who has held restricted securities for one year may, within a three-month
period, sell in "brokers transactions" (as defined by the Rule) an amount equal
to the greater of one percent of the issuer's outstanding securities of such
class or the average weekly reported volume of trading in such securities during
the four calendar weeks preceding the sale, if the conditions specified by the
Rule are satisfied. If such person is not an "affiliate" of the issuer, as such
term is defined by Rule 144, he may, after a holding period of two years, sell
such restricted securities without a volume limitation. Future sales under Rule
144 may have a depressing effect on the market price of the shares of Common
Stock. Of the 3,625,326 shares outstanding following this Offering (not
including shares obtainable upon exercise of the Underwriters' over-allotment
option), 1,333,312 shares will be considered "restricted" stock, of which 26,202
will be eligible for sale under Rule 144 immediately following the Offering.
Beginning 180 days after the closing of this Offering, following the expiration
of certain lockup agreements 1,109,198 additional currently outstanding shares
of restricted Common Stock will be eligible for sale in the public market under
Rule 144. The remaining 197,912 shares of restricted Common Stock will be
eligible for sale from time to time thereafter pursuant to Rule 144. An
additional 314,190 shares of Common Stock issuable upon exercise of outstanding
stock options pursuant to the Company's Amended 1993 Stock Option Plan (the
"Option Shares") may become eligible for resale in the public market at various
times after the closing of the Offering. The Company intends to register the
Option Shares for resale in the public market following expiration of the lockup
period. See "SHARES ELIGIBLE FOR FUTURE SALE."

BROAD DISCRETION WITH RESPECT TO ALLOCATION OF NET PROCEEDS
 
     The Company intends to use the net proceeds of the Offering for working
capital and general corporate purposes, including the marketing of the Company's
EnteraLite(R) Ambulatory Enteral Feeding Pump and funding the growth in the
Company's manufacturing service business. Beyond those uses, if the opportunity
arises, the Company intends to acquire other medical technologies or products
that are similar to or complimentary to the Company's existing engineering
expertise or that readily can be sold through the Company's existing sales
channel. Furthermore, the Company may acquire other design and manufacturing
service firms. Accordingly, management will have significant flexibility in
applying the net proceeds of this Offering. Pending such uses, the Company
intends to invest the net proceeds in short-term interest-bearing,
investment-grade securities. See "USE OF PROCEEDS."
 
   
IMPACT OF ANTI-TAKEOVER MEASURES IN NEW DELAWARE CORPORATION; POSSIBLE ISSUANCE
OF PREFERRED STOCK; CLASSIFIED BOARD
    
 
   
     The Company's Board of Directors and shareholders have approved the
reincorporation of the Company from Nevada to Delaware. The Company anticipates
that this reincorporation will be consummated in November, 1997. See
"Description of Capital Stock -- Delaware Reincorporation." Assuming that this
reincorporation is consummated, certain provisions of the Company's Certificate
of Incorporation and Bylaws and the Delaware General Corporation Law may have
the effect of preventing, discouraging, or delaying a change in the control of
the Company and may maintain the incumbency of the Board of Directors and
management. Such provisions could also limit the price that certain investors
might be willing to pay in the future for shares of the Company's Common Stock.
Pursuant to the Company's Certificate of Incorporation, the Board of Directors
is authorized to fix the rights, preferences, privileges, and restrictions,
including voting rights, of unissued shares of the Company's Preferred Stock and
to issue such stock without any further vote or action by the Company's
stockholders. The rights of the holders of Common Stock will be subject to and
may be adversely affected by the rights of the holders of any Preferred Stock
that may be created and issued in the future. In addition, stockholders do not
have the right to cumulative voting for the election of directors. Furthermore,
the Company's Certificate and Bylaws provide for a staggered board whereby only
one-third of the total number of directors are replaced or re-elected each year.
The Certificate also provides that the provisions of the Certificate relating to
number, vacancies, and classification of the Board of Directors may only be
amended by a vote of at least 66 2/3% of the shareholders. Finally, the Bylaws
provide that special meetings of the stockholders may only be called by the
President of the Company or pursuant to a resolution adopted by a majority of
the Board of Directors.
    
 
   
     The Company is subject to Section 203 of the Delaware General Corporation
Law ("Section 203"), which restricts certain transactions and business
combinations between a corporation and an "Interested Stockholder" owning 15% or
more of the corporation's outstanding voting stock for a period of three years
from the date the stockholder becomes an Interested Stockholder. Subject to
certain exceptions, unless the transaction is approved in a prescribed manner,
Section 203 prohibits significant business transactions such as a merger with,
disposition of assets to, or receipt of disproportionate financial benefits by
the Interested Stockholder, or any other transactions that would increase the
Interested Stockholder's proportionate ownership of any class or series of the
corporation's stock.

<PAGE>   20
 
                                USE OF PROCEEDS
 
   
     The net proceeds to the Company from the sale of 1,300,000 shares of Common
Stock offered by the Company hereby, after deducting underwriting discounts and
commissions and estimated offering expenses, are estimated to be approximately
$18,506,406. Of the net proceeds, the Company intends to repay all outstanding
borrowings, if any, under the Company's revolving line of credit. As of October
21, 1997, the outstanding balance on the Company's revolving line of credit was
$727,277, bearing interest at the bank's prime rate plus 1%.
    
 
     The Company intends to use the remaining proceeds to fund the growth and
development of its design and manufacturing business, as well as its proprietary
products. The Company also intends to use these proceeds for general corporate
purposes, including investment in the marketing and sales of EnteraLite(R)
products, the purchase of related manufacturing equipment, research and
development programs, purchase of raw materials, increases in working capital
associated with continuing sales growth, and acquisitions of complementary
businesses, product lines, or technologies. As of the date of this Prospectus,
the Company is not a party to any negotiations, understandings, or agreements
and has no definitive plans with respect to any such acquisitions.
 
   
     In addition to the proceeds received by the Company from the Offering, the
Company will receive $915,250 from the exercise of warrants by certain Selling
Shareholders in connection with this Offering. The Company will receive an
additional $834,750 in the event the Underwriters exercise their over-allotment
option in full to sell an additional 238,500 shares from the exercise of
warrants held by certain Selling Shareholders. The proceeds received from the
exercise of the warrants will be used for general corporate purposes.
    
 
     The above allocation of portions of the net proceeds reflects the Company's
current plans, and there are likely to be changes influenced by various factors,
including market changes and developments in the medical technology industry.
Pending use of the net proceeds as described above, the Company intends to
invest certain of the proceeds in short-term, investment grade, interest-bearing
investments. See "MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
AND RESULTS OF OPERATIONS -- Liquidity and Capital Resources."

                      SUMMARY MARKET PRICE OF COMMON STOCK
 
     Since May 18, 1997, the Company's Common Stock has been listed on the
American Stock Exchange under the symbol "ZVX." Prior to that time, the
Company's Common Stock traded in the over-the-counter market in the pink sheets
published by the National Quotation Bureau, and was listed on the OTC Bulletin
Board under the symbol "ZVXI". Prior to listing on the American Stock Exchange,
the market for the Company's Common Stock was limited due to the relatively low
trading volume and the small number of brokerage firms acting as market-makers.
The Company anticipates that upon the successful completion of the Offering, the
trading volume will increase.
 
   
     The following table sets forth, for the quarterly periods prior to May 18,
1997, certain information with respect to the high and low bid quotations for
the Common Stock as reported by a market maker for the Company's Common Stock.
The quotations represent inter-dealer quotations without retail markups,
markdowns, or commissions and may not represent actual transactions. For the
period after May 18, 1997, the following table sets forth the high and low
closing sales prices as reported on the American Stock Exchange.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITIONS AND RESULTS OF OPERATIONS
 
GENERAL
 
     ZEVEX designs and manufactures advanced medical devices, including surgical
systems, device components, and sensors for medical technology companies. The
Company also designs, manufactures, and markets its own medical devices using
its proprietary technologies.
 
RESULTS OF OPERATIONS
 
     In each of the three preceding years, a small number of customers accounted
for a significant percentage of total revenues. Fluctuations in the timing and
size of orders from such major customers resulted in changes in the Company's
revenues and product mix, which in turn affected gross margins. As a result of
the foregoing, the Company experiences variations in operating results from
quarter to quarter, and the results of operations for a specific quarter should
not be considered indicative of the results that may be achieved for longer
periods.
 
     The following table sets forth, for the periods indicated, the relative
percentages that certain items in the income statement bear to revenues.

     NINE MONTHS ENDED SEPTEMBER 30, 1997 COMPARED TO NINE MONTHS ENDED
SEPTEMBER 30, 1996
    
 
   
     The Company's revenues increased to $6,311,490 for the first nine months of
1997, from $3,878,255 for the first nine months of 1996, an increase of
approximately 63%. During the first nine months of 1997, 67% of total revenues
resulted from sales to four customers, three of whom were major customers in
1996. Management attributes the increase in revenues due to an increase in the
demand for the Company's products and services.
    
 
   
     The Company's gross profit as a percentage of revenues was 45% for the nine
months ended September 1997, compared to 45% for the nine months ended September
1996.
    
 
   
     Selling, general, and administrative expenses for the nine months ended
September 1997, rose $512,293, from $1,214,623 in 1996, to $1,726,916 in 1997.
Management attributes the increase in these expenses to increased legal expenses
and fees associated with the Company's listing on the American Stock Exchange,
increased payroll and related employee expenses, insurance, and tax costs.
    
 
   
     Research and development expenses vary from quarter to quarter depending on
the number and nature of pending research and development projects and their
various stages of completion. During the first nine months of 1997, research and
development expenses were $521,870, compared to $360,335 for the first nine
months of 1996. Expenses incurred during the first nine months were for the
continued development of new applications for the Company's ultrasound
technology, and proprietary products.
    
 
   
     Operating income for the nine months ended September 1997 increased to
$587,550, or 9% of revenues, from $181,557, or 5% of revenues, in 1996. Net
income increased to $410,763 for the first nine months of 1997
    
 
                                       23
<PAGE>   25
 
   
from a net income of $142,710 in the first nine months of 1996. The increase in
net income during 1997 compared to 1996 is principally due to increased demand
for the Company's products and services, and the mix of product delivered during
that period.
    
 
   
     As of September 30, 1997 the Company's backlog of customer orders was
$7,726,000, compared to $4,357,000 on September 30, 1996. Management estimates
that approximately 45% of the backlog will ship before December 31, 1997.
    
 
     FISCAL YEAR ENDED DECEMBER 31, 1996 COMPARED TO FISCAL YEAR ENDED DECEMBER
31, 1995
 
     The Company's revenues increased to $5,663,733 in 1996 from $5,295,762 in
1995, an increase of approximately 7%. During 1996 and 1995, 67% and 56%, of
total revenues resulted from sales to three customers and two customers
respectively, two of which were major customers in both years. Management
attributes the increase in revenues to an increase in demand for the Company's
products and services during 1996.
 
     Gross profit as a percentage of revenues was 48% in 1996, as compared to
42% in 1995. Management attributes the increase mainly to engineering contracts
completed toward the end of 1996 and to a decrease of non-recurring engineering
tooling expenses billed to customers at cost.
 
   
     Selling, general, and administrative expenses increased during 1996 to
$1,892,317 or 33% of total revenues as opposed to $1,324,928 or 25% of total
revenues in 1995. Increased expenses resulted from the Company's continuing
expansion. An increase in the size of ZEVEX's physical facilities increased
rental, utility, and related expenses. An expanded sales and marketing effort
increased staffing, travel, advertising, and administrative expenses related to
the introduction of the EnteraLite(R) Ambulatory Enteral Feeding Pump. The
Company also had an increase in legal costs associated with patent and trademark
costs as well as increases in expenses related to employees, such as insurance,
taxes, and pension benefits.
    
 
     The Company continued research and development activities independent of
engineering conducted on behalf of its customers, in an effort to develop new
Company owned technologies and products in areas where the Company perceived a
demand. The Company invested $527,562 in 1996 and $502,255 in 1995 directly in
new research and development projects.
 
   
     Operating income decreased to $307,799, or 5% of revenues, in 1996 from
$403,026, or 8% of revenues, in 1995. Alternatively, the Company had net income
of $345,577 or 6% of revenues, in 1996 compared to $316,800, or 6% of revenues,
in 1995. A portion of this increase was due to unrealized gains on marketable
securities in 1996. The remaining changes during 1996 as compared to 1995 are
principally due to the costs addressed previously, as well as the Company's
product mix delivered during the year.
    
 
     THE FISCAL YEAR ENDED DECEMBER 31, 1995 COMPARED TO FISCAL YEAR ENDED
DECEMBER 31, 1994
 
     The Company's revenues increased to $5,295,762 in 1995 from $3,332,437 in
1994, an increase of approximately 59%. During 1995 and 1994, 56% and 55% of
total revenues resulted from sales to two customers in both years. Management
attributes the increase in revenues to an increase in demand for the Company's
products and services.
 
     The Company's gross profit as a percentage of revenues was 42% in 1995, as
compared to 40% in 1994. Management attributes this increase to efficiencies
gained through a reengineering and refixturing of its production area.
 
   
     During 1995, the Company's selling, general, and administrative expenses
grew to $1,324,928 or 25% of total revenues as compared to $1,023,987 or 31% of
total revenues in 1994. The increased expenses resulted from the Company's
decision to increase the size of its operations by expanding the size of the
physical facilities, which in turn increased rental, utility, and related
expenses. The Company also improved customer service by expanding its sales,
marketing, and customer service staff, established more elaborate internal
production and management controls and documentation, and expanded quality
assurance procedures. The
    
 
                                       24
<PAGE>   26
 
Company also had an increase in legal costs associated with patent and trademark
costs, as well as increases in expenses related to employees, such as insurance,
taxes, and pension benefits.
 
     The Company continued research and development activities independent of
engineering conducted on behalf of its customers in an effort to develop new
Company-owned technologies and products in areas where the Company perceived a
demand. The Company invested $502,255 in 1995 and $419,278 in 1994 directly in
new research and development projects.
 
   
     Operating income increased to $403,026, or 8% of revenues, in 1995 compared
to an operating loss of ($127,498), or (3)% of revenues, in 1994. Similarly, the
Company had a net income of $316,800 or 6% of revenues, in 1995 compared to a
net loss of $24,622, or 1% of revenues, in 1994. These increases during 1995 as
compared to 1994 were principally due to the costs addressed previously as well
as the Company's product mix delivered during the year.
    
 
LIQUIDITY AND CAPITAL RESOURCES
 
   
     The Company's increased working capital requirements during the nine months
ended September 1997 and three years ended December 1996 related to increasing
accounts receivable and inventory levels associated with growth in revenues. To
date, working capital has been funded primarily by a combination of increased
accounts payable, borrowings under the Company's revolving line of credit, and
the private placement for the Company's Common Stock.
    
 
   
     During the nine months ended September 1997, the Company produced $410,763
in net income. Cash decreased by $1,949,356 for the nine months ended September
1997, as the Company continued to fund construction of its new manufacturing
facility, and the purchase of new equipment. During the nine months ended
September 1996, the Company had net income of $142,710.
    
 
   
     The Company's investment in the construction of the new facility and
purchases of new research, production, test equipment, and tooling was
$2,854,004 for the first nine months of 1997. In 1996, the company negotiated a
$2,000,000 Industrial Development Bond to finance the construction of a new
51,000 square foot headquarters and manufacturing facility. On October 29, 1996,
the Company completed a transaction in the amount of $50,000 cash and 130,000
shares of unregistered Common Stock of the Company for the purchase of
approximately 3.7 acres of land in Salt Lake City, Salt Lake County, Utah, for
the purpose of constructing a manufacturing facility.
    
 
   
     The Company's working capital at September 30, 1997, was $3,587,841,
compared to $2,403,056 at September 30, 1996. The increase is primarily
attributed to income from operations and the private placement that was
completed in February, 1997. The portion of working capital represented by cash
at such dates was $135,699 and $473,748, respectively.
    
 
     In 1996, the Company used net cash flow in operating activities of
$175,141, as the Company funded an increase in accounts receivable and
inventories.
 
   
     The Company's purchases of land and facilities, and new research,
production, testing equipment, and tooling increased to $619,188 in 1996 from
$241,131 in 1995. The increase in equipment purchases is primarily due to
upgrading the Company's production fixturing, tooling and research and
engineering capabilities in 1995. The Company expects to spend approximately
$240,000 in 1997 for additional manufacturing equipment as well as for normal
replacement of old equipment.
    
 
   
     The Company's working capital at December 31, 1996, was $4,520,781, as
compared to $2,528,419 and $2,269,944 at December 31, 1995 and 1994
respectively. The portion of working capital represented by cash and cash
equivalents at such dates was $2,085,055, $870,333, and $864,332 respectively.
    
 
     On February 12, 1997, the Company completed a private placement of
$1,250,000 of its securities, which consisted of 500,000 units at a price of
$2.50 per unit. Each unit consisted of one share of Common Stock and a warrant
to purchase one share of Common Stock at a price of $3.50 per share.
 
                                       25
<PAGE>   27
 
   
     On December 11, 1996, the Company entered into a $500,000 open line of
credit arrangement with a financial institution. The line of credit was
subsequently amended to increase the amount available under the line to the
present amount of $1,000,000. The line is due May 31, 1998. The line of credit
is collateralized by accounts receivable and bears interest at a rate of prime
plus 1%. The Company owed $60,108 on the line of credit at December 31, 1996 and
$700,000 at September 30, 1997.
    
 
   
     During 1995, the Company generated a positive net cash flow from operating
activities of $247,132, while funding an increase in accounts receivable and
inventories. Operating activities during 1994 resulted in a net negative cash
flow from operating activities of $461,721 while the Company funded an increase
in accounts receivable and inventories.
    
 
   
     The Company purchase of new research, production, testing equipment, and
tooling increased to $241,131 in 1995 from $136,744 in 1994. The increase in
purchases of equipment was primarily due to upgrading the Company's production
fixturing, tooling, research, and engineering capabilities in 1995. The Company
spent approximately $240,000 in 1996 for additional manufacturing equipment as
well as for normal replacement of old equipment.
    
 
     The Company's working capital at December 31, 1995, was $2,528,419, as
compared to $2,269,944 at December 31, 1994. The portion of working capital
represented by cash at such dates was $870,333 and $864,332. The Company
utilizes substantial portions of its cash and cash equivalents from time to time
to fund its operations, including increases in inventories and accounts
receivable in connection with various customer orders.
 
   
     The Company believes that cash generated from operations, together with its
terms under its credit line and the net proceeds from this Offering, will be
sufficient to meet its working capital needs for the next three years. However,
the Company's capital needs will depend on many factors in the execution of the
Company's future strategy, including the Company's growth rate, the need to
finance increased production and inventory levels, the success of the Company's
various sales and marketing programs, and various other factors.

GENERAL
 
     ZEVEX designs and manufactures advanced medical devices, including surgical
systems, device components, and sensors for medical technology companies. The
Company also designs, manufactures, and markets its own medical devices using
its proprietary technologies. The Company's design and manufacturing service
customers are medical technology companies, which sell the Company's systems and
devices under private labels or incorporate the Company's devices into their
products. The Company applies its extensive engineering and regulatory
expertise, developed over its 11-year history, to provide its customers with
integrated solutions to the design and manufacture of their medical devices. The
Company designs and manufactures over 100 different, surgical systems, device
components, and sensors for more than 50 different established and emerging
medical technology companies, such as Alaris Medical Systems, Inc., Allergan,
Inc., Paradigm Medical Industries, Inc., various divisions of Baxter Healthcare
Corporation, Mentor Corporation, SIMS Deltec, Inc., Staar Surgical Company, and
3M Company Healthcare.
 
     ZEVEX's strategy is to augment the continuing growth in its design and
manufacturing service business with the development and commercialization of
proprietary products which utilize the company's technologies or engineering
expertise or which are complementary to the Company's existing proprietary
products. The Company has successfully applied its engineering and regulatory
expertise to the development, commercialization, and marketing of EnteraLite(R),
the Company's proprietary Ambulatory Enteral Feeding Pump for patients who must
receive direct gastrointestinal nutritional therapy. The EnteraLite(R) pump
provides patients with maximum mobility while delivering enteral solutions with
unprecedented accuracy.
 
OVERVIEW OF MEDICAL TECHNOLOGY INDUSTRY
 
     Growth of Medical Technologies. Demand for health care in the United States
has grown rapidly in recent years and is expected to continue to grow as the
population ages. At the same time, advancements in medical science, as well as
in electronics, computers, ultrasound, new materials, lasers, and other
technologies have dramatically expanded the number and variety of medical
devices and systems. The most advanced medical procedures and techniques, many
of which use advanced medical devices, now are common treatments under many
health insurance plans. As insurance companies and federal and state governments
have expanded the medical procedures for which health care providers are
reimbursed, demand has grown for the medical devices and systems needed for
these procedures. More recently, in response to increasing pressure in the
United States to control rising health care costs, medical technology companies
have developed advanced medical devices and systems that improve patient
outcomes and reduce the overall cost of health care.
 
     Need for Efficient Developers of Medical Devices. As medical products have
incorporated the latest developments in various technologies, the cost of
product development and the length of the development cycle have increased
substantially. The risks in developing and launching new medical products also
have increased significantly as competition in the highly fragmented $30 billion
U.S. medical technology industry has increased. As a result, medical technology
companies face increased pressure to bring new products to market in the
shortest possible time and at the most efficient cost, while maintaining a high
level of quality in the commercial product.
 
     Regulatory Complexity. At the same time, the FDA and the European Union
have adopted increasingly stringent and evolving regulatory requirements for the
manufacture of medical products. In the United States, certain medical products
are subject to application to the FDA for pre-market approval ("PMA") and many
other medical products require clearance to market ("510(k) approval"). In
addition, products are subject to regulation with respect to manufacturing,
labeling, distribution, post-market reporting, and promotion. Under European
Union quality standards to be effective in 1998, the design of medical products
must satisfy specific engineering design process standards. To market and sell
their products, medical technology companies must also invest significant
financial resources to establish and maintain manufacturing facilities that
comply with the FDA's Good Manufacturing Practices ("GMP") requirements in the
U.S. and the European Union's
 
                                       27
<PAGE>   29
 
quality system standards, such as certification from the International
Organization for Standardization ("ISO"). Even after the often lengthy and
time-consuming process of obtaining FDA clearance and ISO certification, medical
technology companies must thereafter devote substantial managerial oversight to
ensure continued compliance with FDA and ISO requirements.
 
     Opportunities for ZEVEX. Management of the Company believes that advances
in technology, increasing regulatory complexity, and intensified competition
will lead many medical technology companies to expand their out-sourcing of
design and manufacturing services in order to be more efficient. Management
believes that the Company is well positioned to benefit from this increasing
trend towards out-sourcing, given the extensive engineering and regulatory
expertise that ZEVEX has developed over its 11-year history of designing and
manufacturing medical products. Specifically, the Company may often times be
able to profitably design and manufacture medical devices or systems more
quickly, at a lower cost, and with higher quality than its medical technology
customers can do themselves. Management also believes that it can continue to
leverage that same extensive engineering and regulatory expertise into the
design and manufacture of the Company's own proprietary medical devices.
Management believes that this two-pronged strategy in the $30 billion medical
technology marketplace may allow the Company to benefit from the increasing
demand for the design and manufacturing of medical devices and systems, as well
as from the sale of the Company's own proprietary medical devices.
 
ADVANTAGES OF OUT-SOURCING DESIGN AND MANUFACTURING TO ZEVEX
 
     ZEVEX provides customized integrated solutions to the design,
manufacturing, and regulatory challenges associated with advanced medical
devices and systems. Many emerging medical technology companies simply do not
have the engineering, manufacturing, and regulatory expertise necessary to
quickly and efficiently bring a medical device from the concept stage to
commercial use. Even larger, well-established medical technology companies,
which may have the capital resources to develop such expertise, may lack the
required expertise or the time to accumulate such expertise in order to meet the
market demand for their particular device. Moreover, in some instances, these
medical technology companies may simply elect not to devote their resources to
the design and manufacture of their medical devices or systems, including
obtaining and maintaining the necessary regulatory approvals and industry
certifications for their manufacturing facilities. ZEVEX can often bring its
customer's device from concept to market more quickly and efficiently, as well
as provide the on-going manufacturing capability to meet the market demand.
ZEVEX's design and manufacturing services enable its customers to focus their
resources on the research of new products and the marketing of their existing
products, including those manufactured by ZEVEX. In summary, ZEVEX offers its
manufacturing service customers the following advantages:

DEVICES THAT ZEVEX MANUFACTURES FOR OTHERS AND THEIR MARKETS
 
     Surgical Devices -- Ophthalmic. The Company designs and manufactures
several ultrasonic phacoemulsification handpieces and systems for the surgical
removal of cataracts. Cataracts are a condition, usually age related, in which
the natural lens of the eye becomes progressively clouded. This clouding
obstructs the passage of light into the eye and can lead to blindness. Most
patients blinded by cataracts can be surgically cured by removing the clouded
lens and replacing it with an intraocular lens. Phacoemulsification is a method
of cataract extraction that uses ultrasound waves to break the natural lens into
small fragments that can be removed through a hollow needle. Phacoemulsification
requires only a three to four millimeter incision, compared to incisions of up
to 12 millimeters for other techniques. Phacoemulsification is currently
utilized in more than 80 percent of cataract procedures in the United States.
Based on a recent market study, the world market for phacoemulsification systems
exceeds $100 million per year. The Company currently manufactures two complete
phacoemulsification systems for one customer, Paradigm Medical Industries, Inc.
These two systems include a basic ultrasonic system and a high-end system which
embodies both laser and ultrasound energy sources. The Company's two major
customers for these phacoemulsification handpieces and systems used in
ophthalmic surgery are Allergan and Paradigm Medical Industries, Inc.
 
   
     Surgical Devices -- Liposuction. The Company has recently applied its
engineering and manufacturing expertise with respect to ultrasonic handpieces
used in ophthalmic surgery to the design and manufacture of ultrasonic
handpieces to be used in liposuction surgery. Liposuction, or the removal of
body fat, is one of the most popular cosmetic procedures performed today.
Current liposuction procedures involve the use of a metal cannula to sheer the
fat from the patient. This requires the physician to exert a large amount of
force to facilitate the procedure. In ultrasonically assisted liposuction, a
generator sends ultrasonic waves through a probe which is inserted under the
skin. The ultrasonic energy emulsifies the fat, which can then be easily
aspirated away. This form of liposuction surgery can significantly reduce trauma
to the patient as compared with the results from the metal cannula handpieces
that have been used primarily in the past for such surgery. According to the
American Society of Plastic and Reconstructive Surgeons, the number of
liposuction procedures performed in the United States more than doubled from
approximately 51,000 in 1994 to approximately 109,000 in 1996. The Company's
customer for its ultrasonic liposuction surgery handpiece is Mentor Corporation,
which had total sales in its fiscal year ended March 31, 1997 of approximately
$203 million from sales of various products in the plastic surgery, urology, and
ophthalmology marketplaces. Mentor Corporation produces an ultrasonic
liposuction system for plastic surgery of which the ZEVEX manufactured handpiece
is one component.
    
 
     Medical Sensors. The Company designs and manufactures a variety of
non-invasive ultrasonic sensors for the detection of air bubbles and the
monitoring of liquid levels in medical devices. These sensors can be applied to
the exterior of a liquid-containing vessel or tubing, thereby eliminating the
possibility of liquid contamination, and are designed to meet the specifications
of customers which then incorporate the sensor into their own medical devices.
The Company's air bubble detectors monitor intravenous fluid lines in a variety
of devices and systems, including drug infusion pumps, hemodialysis machines,
blood collection systems, and cardiopulmonary bypass systems. Ultrasonic sensors
include a piezoelectric sensing element and can include a circuit board which
drives the element, processes signals, and interfaces with the customer's
device. The Company's liquid level detectors are used to monitor critical levels
of liquids in various reservoirs used in surgery, such as those employed in
cardiopulmonary bypass systems. The Company holds a patent with respect to key
features of its non-invasive, ultrasonic liquid level detectors. The Company
estimates that
 
                                       32
<PAGE>   34
 
the 1997 U.S. market for air bubble and liquid level detectors for medical uses
is approximately $60 million. The Company's primary customer for these medical
sensors is Alaris Medical Systems, Inc. (a company recently formed as a merger
of several companies, including the Company's customer formerly known as IVAC).
 
ZEVEX'S PROPRIETARY PRODUCTS
 
     EnteraLite(R) Ambulatory Enteral Feeding Pump. In September 1996, the
Company began selling the EnteraLite(R) Ambulatory Enteral Feeding Pump for
patients who must receive direct gastrointestinal nutritional therapy. Enteral
feeding is a means of providing nutrition to patients who have gastrointestinal
disorders, such as short bowel syndrome, Crohn's Disease, bowel
pseudo-obstruction, and other serious digestive disorders, which prevent them
from normally digesting food. Many enteral feeding patients require the
continuous administration of nutritional solutions throughout the day, which
requires the patient to carry an enteral feeding pump throughout the day.
Management believes that the EnteraLite(R) pump is the lightest, most compact
enteral feeding pump on the market, possessing unprecedented safety and accuracy
in liquid nutrition delivery for the patient. The EnteraLite(R) has a 24-hour
battery, which is one-third longer than the battery life of any competing
device. The EnteraLite(R) pump carries a two-year warranty, which is twice the
average in the industry. The EnteraLite(R) requires the use of disposable
feeding bags and tube sets, both of which are sold by the Company. The Company
has been awarded two U.S. patents for technology used in the EnteraLite(R) pump.
The Company has also received Notices of Allowance from the U.S. Patent and
Trademark Office ("PTO") for four additional patents which relate to various
aspects of the EnteraLite(R) pump. Additional patents are pending with the PTO.
Industry sources estimate that the total 1997 U.S. market for enteral feeding
pumps and related sets of disposable products, such as feeding bags and tube
sets, is nearly $200 million.
 
     BottleWatch(R) Liquid Level Indicator. BottleWatch(R) noninvasively
monitors liquid levels in bottles of saline solutions which are used extensively
in cataract and retinal surgery. Saline solution is required to nourish and
support the delicate structures of the eye during ocular surgery, the depletion
of which can complicate surgery, or in the worst case lead to irreparable damage
to the patient's eye. When the liquid level drops below the user-specified
position of the BottleWatch(R), audible and visible alarms are immediately
activated. Revenues from BottleWatch(R) have been immaterial and the Company
does not anticipate significant revenues from this product in the future.
 
SIGNIFICANT CUSTOMERS FOR WHICH ZEVEX PROVIDES DESIGN AND MANUFACTURING SERVICES
 
   
     During the first nine months of 1997, the Company provided design and
manufacturing services for over 100 devices to more than 50 customers. Sales of
its design and manufacturing services to foreign customers accounted for
approximately 7% of revenues during 1996 and 1995. The Company's customers for
its design and manufacturing services are medical technology companies, which
sell the Company's systems and devices under private labels or incorporate the
Company's devices into their products. Generally, the Company seeks to obtain
design and manufacturing arrangements from its customers for a specified period
of time, typically with initial periods of three to five years followed by
annual renewals. The Company rarely undertakes design work if it does also not
obtain a contract for the accompanying manufacturing work. Three of the
Company's design and manufacturing customers, Alaris Medical Systems, Inc.,
Allergan, and Paradigm Medical, Inc. accounted for approximately 66% of the
Company's total revenues in 1996. During the first nine months of 1997, these
same three customers, plus a fourth customer, Mentor Corporation, accounted for
67% of the Company's total revenues for that same period. Each of those major
customers are discussed below.
    
 
     Alaris Medical Systems, Inc. Alaris Medical Systems, Inc. ("Alaris") is a
leading provider of infusion systems and related technologies to markets in
North America, Western Europe, Latin America, and Asia. Alaris is the surviving
corporation from a series of mergers in 1996 among IMED International Trading
Corp., IVAC Medical Systems, Inc., IVAC Holdings, Inc., and Alaris. In 1996,
Alaris generated revenues in excess of $346 million principally from sales of
infusion therapy systems (which includes infusion pumps and disposable fluid
administration sets) and vital signs measurement products. During 1996, Alaris
had pro forma revenues of approximately $292 million from its infusion systems
and approximately $33 million from its vital
 
                                       33
<PAGE>   35
 
   
signs measurement products. In 1996, Alaris had approximately 214,000 large
volume infusion pumps installed in the United States, with a U.S. market share
of approximately 40% of the installed base. Since 1987, the Company has designed
and manufactured ultrasonic air bubble detectors for Alaris infusion pumps under
the Alaris name or under the name of an Alaris predecessor. During the first
nine months of 1997, revenues from Alaris comprised approximately 20% of the
Company's revenues.
    
 
   
     Allergan. Allergan is a leading provider of specialty therapeutic eye care
products throughout the world. In 1996, Allergan generated revenues in excess of
$1 billion principally by selling prescription and non-prescription
pharmaceutical products in the areas of ophthalmology and skin care, intraocular
lenses and other ophthalmic surgical products, and contact lens care products.
During 1996, Allergan had revenues of $148 million in its surgical product
business, the business in which Allergan sells different phacoemulsification
devices for the surgical removal of cataracts. Since 1989, ZEVEX has designed
and manufactured phacoemulsification devices marketed by Allergan. During the
first nine months of 1997, revenues from Allergan comprised approximately 14% of
the Company's revenues. The Company's current, nonexclusive manufacturing
contract with Allergan has a three-year term beginning January 1, 1997.
    
 
   
     Paradigm Medical Industries, Inc. Paradigm Medical Industries, Inc.
("Paradigm") develops and markets ophthalmic surgical systems designed for
minimally invasive cataract removal. In 1996, it generated revenues of $295,000,
principally from the sale of an ultrasonic surgery system used to remove
cataracts. Since 1993, the Company has manufactured phacoemulsification systems
for Paradigm. Beginning in late 1996, the Company designed and manufactured for
Paradigm the prototypes of Paradigm's Photon laser cataract surgical system
(except for certain laser-related components). This new system integrates
ultrasound and laser technologies and includes a custom computer monitor user
interface and unique software developed by the Company. Paradigm's PMA
application for the Photon system with respect to ophthalmic surgery is pending
with the FDA. Until clearance is received from the FDA to market the Photon,
including the laser component, in the United States, the Company is
manufacturing for Paradigm an ultrasonic-only version of the Photon which
Paradigm markets under the name "Precisionist Thirty-Thousand." The Precisionist
Thirty-Thousand is the platform for the Photon which can be upgraded by adding
the laser module. The Company's contract with Paradigm, which expires September
23, 1999, prohibits the Company from selling, distributing, developing, or
manufacturing ophthalmic medical lasers in competition with Paradigm during the
term of the contract and for a period of two years following termination. During
the first nine months of 1997, revenues from Paradigm comprised approximately
21% of the Company's revenues.
    
 
   
     Mentor Corporation. Mentor Corporation ("Mentor") develops, manufactures
and markets a broad range of products for the medical specialties of plastic and
reconstructive surgery, urology, and ophthalmology. For its fiscal year ended
March 31, 1997, Mentor generated revenues of approximately $203 million, of
which approximately $106 million was from sales of plastic surgery products and
approximately $36 million was from sales of ophthalmology products. Since 1992,
ZEVEX has designed and manufactured phacoemulsification devices marketed by
Mentor. ZEVEX recently designed and began the manufacture of handpieces for an
ultrasonic liposuction surgery system produced by Mentor. The Company's contract
with Mentor, which expires September 30, 1998, prohibits the Company from
designing or manufacturing ultrasonic liposuction handpieces in competition with
Mentor during the term of the contract and for a period of three years following
termination. During the first nine months of 1997, revenues from Mentor
comprised approximately 12% of the Company's revenues.
    
 
BACKLOG
 
   
     At September 30, 1997, the Company had a backlog of orders for medical
devices to be manufactured by the Company for other medical technology companies
of approximately $7,726,000. Management estimates that approximately 45% of the
backlog will ship before December 31, 1997. For purposes of the above figures,
backlog includes all orders received by the Company pursuant to purchase orders
which have not been completed and shipped by the Company. This does not include
any backlog for the Company's proprietary products, because the Company
manufactures these devices and holds appropriate levels in inventory for sale to
customers. Some of the orders included in the backlog may be canceled or
modified by customers without significant penalty. In addition, since customers
may place orders for delivery at various times throughout the
    
 
                                       34
<PAGE>   36
 
year, and because of the possibility of customer changes in delivery schedules
or cancellation of orders, the Company's backlog as of any particular date may
not be a reliable indicator of future sales.
 
DESIGN AND ENGINEERING CAPABILITIES
 
     The Company has extensive design and engineering capabilities. In most
instances, the Company's manufacturing service customers rely on the Company
from the outset of their project for complete design, engineering, testing,
component analysis, and regulatory compliance for their medical device or
system. Indeed, over the Company's 11-year history, the Company's engineering
staff has performed substantially all of the design and engineering work for
such medical devices or systems. In other instances, customers have come to the
Company with final drawings for devices that they believe are ready for
manufacturing. In such cases, the Company has revised and tested the customer's
existing design prior to manufacturing the device or system, and, in many cases,
the Company's engineers have been able to identify and offer alternatives to the
customer's design that have improved performance or produced manufacturing
efficiencies.
 
     Team Approach. The Company approaches each engineering project using a team
of engineers and technicians of various disciplines who understand the technical
requirements of the particular project. Each team includes representatives from
various engineering disciplines, including manufacturing, test, and quality
engineers, who help design a device that can be manufactured in a manner that
meets or exceeds customer specifications and the applicable regulatory
requirements.
 
     Close Cooperation with the Customer. The Company's team of engineers work
closely with the customer during all phases of the design, engineering, and
testing of the customer's device or system. This cooperative approach is used to
assure that the customers' expectations are met or exceeded in the final
product.
 
     Integration of Engineering Staff. The Company integrates its engineering
staff throughout its operations, including sales and marketing, customer
relations, materials management, quality assurance, regulatory compliance, and
manufacturing. The Company's engineers assist the Company's sales and marketing
personnel in evaluating requests for proposals and developing project-specific,
solution-oriented responses, bids, cost estimates, and project plans. Similarly,
the Company's project engineers act as customer contacts throughout the design
and engineering phase and have responsibility for all aspects of a customer's
project, including coordinating the component parts necessary for the device,
quality assurance procedures, regulatory compliance, and the manufacturing
process. The Company also provides its customers with design information and
other support during the FDA's 510(k) approval or PMA process, but does not
assist in the testing, studies, and human clinical trials associated with these
approvals.
 
     State-of-the-Art Engineering Technologies. The Company has made significant
investments in state-of-the-art equipment to support its design and engineering
staff, including engineering design and testing stations and three-dimensional
computer aided design ("CAD") software. The Company's engineers use computers to
design software, to design and lay out surface mount circuit boards, and to
design custom integrated circuits. The Company's engineers utilize
stereolithography which allows for rapid production of prototypes from CAD
drawing files before commencement of manufacturing of the commercial device or
system. Utilizing its own software design capabilities, the Company has also
created what management believes is the most sophisticated modeling software for
ultrasonic device development. This capability speeds the product development
process for ultrasonic devices and improves the quality of the final device.
 
     Engineering Service Contracts. The Company performs design and
manufacturing services for many customers under purchase orders. With major
customers the Company enters into manufacturing contracts which allow for
recurring purchase orders. Under these contracts, each device, product design,
patent, and other proprietary right developed by the Company in performing
engineering services becomes the property of the customer. The Company usually
receives the manufacturing rights to a device for a period generally ranging
from three to five years, with annual renewals thereafter. Generally, the
Company provides non-recurring engineering services under a project plan that
identifies the engineering tasks, deliverables, and time schedule. Typically,
such services are billed as progress milestones are attained and are cancelable
at any time.
 
                                       35

     Engineering Staff. At September 30, 1997, the Company's engineering staff
consisted of 27 engineers. The engineering staff has experience in a variety of
disciplines, as follows:

MANUFACTURING CAPABILITIES
 
     As the design and engineering of a device or system nears completion, the
members of the project team with direct responsibility for manufacturing,
quality assurance, test engineering, and materials assume a greater role. The
project team implements a materials management system and develops an assembly
process and product testing and quality assurance procedures to produce
high-quality devices or systems that satisfy customer specifications as well as
the FDA's GMP and ISO 9001/EN 46001 quality standards. Often, manufacturing
begins with a relatively small number of pre-production units, which are used by
the customer for clinical trials. The Company and the customer frequently work
closely together to make engineering and manufacturing refinements during this
pre-production phase.
 
     Manufacturing Cells and Computerization of the Manufacturing Process. Each
instrument is manufactured in a dedicated manufacturing cell on the Company's
manufacturing floor. These cells are flexible and can be expanded or modified as
needed, enabling the Company to adjust production volumes quickly in response to
customer orders. Each cell is equipped with computer instruction centers.
Production personnel actually view pictures of the device that they are making
or assembling on the computer screen in its various stages of production or
assembly, along with the pertinent instructions for each step of the process.
This computerized manufacturing system also allows test data to be entered and
archived in the course of the manufacturing process. The advantage of this
system is that production personnel always have access to the current version of
instructions, thereby eliminating the possibility of using obsolete
instructions. This system also allows accurate entry and retrieval of test data,
again without the difficulties of a tracking system documented on paper.
 
     Materials Requirements System. The Company uses a fully integrated
materials requirements system. This system includes sales order entry,
purchasing, inventory control, production control, and cost accounting and helps
the Company manage material acquisitions and inventory for the various projects
in production at any one time and facilitates the planning and control essential
to building products on accelerated time schedules.
 
     Manufacturing Contracts. The Company generally executes manufacturing
contracts with major customers at the beginning of engineering projects, at
which time the Company provides customers with budgetary estimates of
manufacturing costs. Pricing is typically based on the Company's expected cost
plus a mark-up. Although manufacturing contracts rarely include minimum
production requirements, they usually grant the Company exclusive manufacturing
rights for initial periods generally ranging from three to five years, with
annual renewals thereafter. The Company generally warrants conformity to design
specifications, warrants against defects in materials and workmanship, and in
certain instances indemnifies its customers against losses arising out of
product defects. Such warranties customarily last at least 14 months from the
date of manufacture and sometimes longer. The Company has not experienced any
material claims against these warranties from its manufacturing service
customers. In addition, the Company in many cases enters into repair and service
agreements with these customers that set forth the pricing and terms under which
the
 
                                       36
<PAGE>   38
 
Company provides repair, replacement parts, and needed services or upgrades that
are not covered under warranty. Although most of the Company's manufacturing is
performed under manufacturing contracts, some devices are manufactured only
under purchase orders.
 
     Suppliers. The Company purchases its component parts and raw materials from
various suppliers. The Company is not dependent on any single supplier for any
item. The Company believes that it can acquire from various sources on a timely
basis, the component parts and raw materials necessary for the Company to meet
obligations to its manufacturing service customers, and to manufacture its own
proprietary products.
 
QUALITY ASSURANCE AND REGULATORY COMPLIANCE
 
   
     The Company emphasizes quality throughout its operations and integrates its
quality assurance and quality engineering programs throughout each engineering
and manufacturing phase, a process that involves the Company's senior management
and executive officers. At September 30, 1997, the Company employed 8 personnel
in its quality assurance, quality engineering, and regulatory departments.
    
 
     Quality Assurance Procedures. Quality assurance procedures are integrated
into every aspect of a device's manufacturing cycle. The Company establishes a
quality assurance program for each instrument, which includes a "zero defects"
objective. Substantially all component parts and product subassemblies that are
manufactured by others receive a control number, and samples are inspected and
tested. The Company requires all vendors that supply components to satisfy
certain quality standards. On the manufacturing floor, quality assurance
personnel implement testing procedures at interim points during the assembly
process. A separate product test group which reports to the production manager
conducts a final test when the instrument is fully-assembled and ready for
shipping. In addition, prior to shipping, a quality inspector reviews each
instrument for proper labeling and paperwork.
 
     Compliance with FDA GMP Requirements. The Company is registered with the
FDA as a medical device manufacturer. Management believes that the Company is in
compliance with FDA GMP requirements and has implemented internal systems to
maintain such compliance. The Company has experienced regularly scheduled and
unscheduled FDA audits in past years, none of which required significant changes
to its facilities or processes and none of which required discontinuation of
normal operations. See "BUSINESS -- Governmental Regulation Within the United
States."
 
     ISO Certifications. The Company has obtained certifications from the
International Organization for Standardization ("ISO"), the first quality system
standard to gain worldwide recognition, including the European Union, Japan, and
the United States. As many medical technology companies expand sales of products
in international markets, compliance with these international quality standards
has increased in importance. The Company first obtained the ISO 9001
certification from the National Standards Authority of Ireland, an ISO notified
body, in 1996. This designation is the highest level of ISO 9000 certification
and indicates that the Company has met stringent design, manufacturing, and
testing standards for its devices. The Company also has achieved an additional
EN 46001 certification from the same organization, which indicates that the
Company has met additional quality standards specific to medical devices. The
Company's ISO 9001/EN 46001 certifications serve as a marketing tool that
enhances the Company's competitive position in the industry, especially with
respect to medical technology companies with internal manufacturing facilities
that have not gone through the costly and time-consuming ISO certification
processes.
 
RESEARCH AND DEVELOPMENT FOR ZEVEX'S PROPRIETARY PRODUCTS
 
   
     As of September 30, 1997, the Company employed three employees in full-time
research and development capacities and utilized the efforts of its other design
and engineering staffs in connection with certain research and development
projects. The research and development efforts of the Company are focused on new
and existing proprietary products. During the last two fiscal years, the Company
continued independent research and development activities with respect to the
design and development of new and improved devices, spending $527,562 in 1996
and $502,255 in 1995. In both 1996 and 1995, research and development costs
represented approximately 9% of the Company's revenues. During the first nine
months of 1997, the Company's research and development expenditures totalled
$521,870, representing 8% of revenues
    
 
                                       37
<PAGE>   39
 
for the same period. The Company's research and development efforts during these
periods were devoted to several products, most notably the EnteraLite(R)
Ambulatory Enteral Feeding Pump.
 
MARKETING AND SALES
 
     Marketing and Sales of ZEVEX's Design and Manufacturing Services. The
Company generates new design and manufacturing projects from customers using
direct sales personnel who are trained in the Company's engineering expertise
and manufacturing capabilities. Project engineers also participate extensively
in sales and marketing activities. In addition, the Company promotes its design
and manufacturing capabilities at industry trade shows, by advertising in
leading industry publications, and by obtaining referrals from customers, former
employees of customers, and other persons who are familiar with the Company's
services.
 
     Marketing and Sales of ZEVEX's EnteraLite(R) Ambulatory Enteral Feeding
Pump. The Company has developed a network of over 50 independent manufacturer's
representatives who sell the EnteraLite(R) pump and related disposable delivery
sets. These representatives are selected based upon their experience with the
home healthcare market served by EnteraLite(R) and they sell directly to home
healthcare service providers, including hospitals with such divisions. These
representatives are compensated solely on a commission basis. The efforts of
these representatives are supported by a clinical support coordinator and are
overseen by a national sales manager, both of whom are full-time employees of
the Company. Presently, EnteraLite(R) pumps are purchased directly from the
Company. In the larger market for enteral products, pumps are often placed with
the customer free of initial capital investment, with the cost of the equipment
recovered through the customer's commitment to purchase disposable delivery sets
for a specified period of time. In the future, the Company intends to offer
similar programs directly to its customers to improve its competitive market
position.
 
COMPETITION
 
     Competition for ZEVEX's Design and Manufacturing Services. The Company's
primary competitors in design and manufacturing services are other manufacturers
that operate in the medical technology industry. The primary competitive factors
in medical instrument design and manufacturing include quality, regulatory
compliance, engineering competence, cost of the non-recurring engineering design
component, price of the manufactured product, experience, customer service, and
ability to meet design and production schedules. Competition is primarily
limited to those companies that meet the minimum applicable regulatory
requirements of the FDA and international standards for manufacturing and
design. In the future, the Company is likely to compete against new entrants
into the industry as out-sourcing expands in medical technology products. For
example, medical technology companies with design and manufacturing capabilities
(especially those with excess capacity) and large electronic contract
manufacturers and defense department contractors with extensive engineering
expertise may undertake the design and/or manufacture of medical devices.
 
     Competition for ZEVEX's EnteraLite(R) Ambulatory Enteral Feeding Pump. Two
competitors exist in the U.S. market for ambulatory enteral feeding pumps. Ross
Laboratories, a division of Abbott Laboratories, offers the Companion pump,
which was originally introduced to the market in the late 1980's. The Company
estimates that Ross holds a market share of 45% for ambulatory and
non-ambulatory enteral feeding applications. Also, Sherwood Medical offers the
kangaroo PET enteral feeding pump, which is limited because it can only be
operated in an upright position. It is estimated that Sherwood presently holds
greater than 35% of the total market for enteral pumps and disposable sets in
both ambulatory and non-ambulatory applications.
 
PATENTS, TRADEMARKS, AND OTHER PROPRIETARY RIGHTS
 
     Patents. The Company currently holds three United States patents. The
Company's first patent, U.S. Patent No. 5,438,868, relates to a non-invasive
ultrasonic liquid level indicator. The technology disclosed in the patent is
embodied in a liquid level indicator currently marketed by the Company under the
trademark BottleWatch(R). The Company also holds two patents, U.S. Patent Nos.
5,514,102 and 5,531,680, which relate to its EnteraLite(R) Ambulatory Enteral
Feeding Pump. U.S. Patent No. 5,514,102 relates to the use of pressure
monitoring to improve the accuracy of fluid delivery by the pump. The accuracy
provided by the pressure
 
                                       38
<PAGE>   40
 
monitoring technology is complemented by the novel mechanism for monitoring pump
rotor movement disclosed in U.S. Patent No. 5,531,680. By using optical sensors,
the EnteraLite(R) pump is able to ensure that rotor movement occurs properly and
allows confirmation of the solution delivery rate. This technology enables the
EnteraLite(R) pump to operate without drip chambers and similar devices which
limit the mobility of the patient, while maintaining a high degree of flow rate
accuracy.
 
     Patent Applications. The Company is actively pursuing seven U.S. patent
applications, four of which have been allowed by the United States Patent and
Trademark Office. Two of the allowed patent applications relate to the
disposable delivery sets which are loaded into the EnteraLite(R) pump and which
carry the enteral feeding solution to the patient. The technology disclosed in
these patent applications prevents accidental flow through the delivery set
which passes through the pump. This helps to prevent accidental overdosing of
solution in the event that the patient or caregiver forgets to load the delivery
set in the pump or loads the delivery set improperly. The allowed patent
applications also include a patent for a clamp which holds the pump to a fixed
object, such as a hospital bed, and allows the user to change the position of
the pump to ensure comfort. The Company has also received a notice of allowance
on a patent application which claims a novel apparatus and method for detecting
occlusions in the delivery set which might prevent proper administration of the
enteral feeding solution. While the United States is currently the Company's
primary market, the Company has also pursued foreign patents on its proprietary
technology. Specifically, the Company has filed six patent applications under
the Patent Cooperation Treaty and is in the process of nationalizing several of
these applications. The Company intends to file appropriate applications for
additional patents, both in the United States and in foreign countries on
additional technology it is currently developing.
 
     Trademarks. The Company has registered the trademarks EnteraLite(R) and
BottleWatch(R) with the United States Patent and Trademark Office and has
pending registrations for ZEVEX(TM). Additionally, the Company has procured
registrations for BottleWatch(R) in Australia, Belgium, Canada, France, Germany,
Italy, Japan, Luxembourg, the Netherlands, and the United Kingdom. The Company
intends to file appropriate applications for additional trademarks in the United
States and foreign countries.
 
     Agreements with Employees and Others. The Company enters into appropriate
confidentiality agreements, noncompetition agreements, and invention assignment
agreements with its employees, consultants, contractors, vendors, customers, and
others to protect the confidential information of its customers, to establish
the Company's rights or the rights of its customers in the technologies it
develops, and to establish contractual grounds upon which the Company can
enforce such rights, if necessary.
 
GOVERNMENTAL REGULATION WITHIN THE UNITED STATES
 
     Because the Company provides design and manufacturing services to producers
of medical devices, as well as designs and manufactures its own medical devices,
the Company's manufacturing facilities, the medical devices of the Company's
customers, and the Company's own medical devices are subject to extensive
regulation by the FDA under the Food Drug and Cosmetics Act ("FDC Act").
Manufacturers of medical devices must comply with applicable provisions of the
FDC Act and associated regulations governing the development, testing,
manufacturing, labeling, marketing, and distribution of medical devices and the
reporting of certain information regarding their safety. The FDA's regulation of
medical devices and of the manufacturing facilities in which those devices are
made are summarized in the following sections.
 
     FDA's Approval of Medical Devices. The FDA classifies medical devices into
three classes (Class I, II, or III) on the basis of the controls deemed
necessary by the FDA to reasonably ensure product safety and efficacy. Class I
devices are subject to general controls (e.g., labeling, premarket notification
and adherence to GMP) and Class II devices are subject to general and special
controls (e.g., performance standard and guidelines). Generally, Class III
devices are higher-risk devices and cannot be marketed until after receiving FDA
"pre-market approval" ("PMA"). The Company currently manufactures two Class III
medical devices that require PMA application prior to commercialization. A PMA
application must be supported by valid scientific evidence, which typically
includes extensive data, including preclinical and clinical trial data to
demonstrate safety and efficacy of the device. The application also must contain
the results of all relevant bench tests, laboratory and animal studies, a
complete description of the instrument and its components, and a detailed
description of the methods, facilities, and controls used to manufacture the
device. In addition, the
 
                                       39
<PAGE>   41
 
application must include the proposed labeling. Although the Company's services
do not extend to assistance with testing, studies, and human clinical trials,
the Company does provide its customers with required design information and
other support during the PMA process. Typically, the FDA will inspect the
manufacturer prior to granting PMA approval. If the FDA identifies deficiencies
in the manufacturing process, it could delay PMA approval. Delays in the PMA
process could affect the timing of manufacturing services provided by the
Company. Currently, an FDA review of a PMA application generally takes one to
two years from the date the application is submitted, but often is significantly
extended by an FDA request for more information or clarification of information
previously submitted. The PMA process can be expensive, uncertain, and lengthy,
and a number of devices for which PMA approval has been sought have never been
approved for marketing. Until a device subject to the PMA process receives the
FDA's approval, it cannot be sold commercially in the United States. Notably,
after PMA approval has been obtained, subsequent modifications to the device,
its labeling or manufacturing may require additional FDA approvals. For Class I
and Class II devices, and certain Class III devices, FDA clearance may be
obtained through a "510(k) notification process" pursuant to which the FDA
determines that a medical device is "substantially equivalent" to an existing,
legally marketed predicate device or a predicate device marketed before May 28,
1976. Clinical testing of certain devices may be required as part of the 510(k)
notification process. Currently, several of the Company's customers have
submitted or intend to submit a request to the FDA for clearance for marketing
under a 510(k) notification for devices to be manufactured by the Company.
Additionally, the Company is required to follow the FDA's 510(k) notification
procedures with respect to its own medical devices. The time required to receive
510(k) approval can vary, but may take several months. There can be no assurance
that the FDA will find a device substantially equivalent and allow marketing of
such device. Even if the device is found substantially equivalent, the clearance
process may be delayed if the FDA requires additional information.
 
     Ongoing FDA Requirements for Commercialized Medical Devices. Any medical
device manufactured or distributed by the Company for its customers or for
itself pursuant to FDA clearances or approvals is subject to pervasive and
continuing regulation by the FDA, including record-keeping requirements and
reporting of adverse experiences associated with the use of the instrument.
 
     FDA's GMP Requirements. In addition to the regulation of medical devices
described above, any manufacturing facility of a medical device that requires
FDA approval is also subject to regulation by the FDA, as well as by certain
state agencies. The FDA regulations in this regard are referred to as "good
manufacturing practices" ("GMP"). Pursuant to these GMP requirements, medical
device manufacturers are required to register their establishments and list
their devices with the FDA (as well as with certain state agencies) and are
subject to periodic inspections by the FDA (and certain state agencies). The FDC
Act requires devices to be manufactured in accordance with GMP regulations,
which impose certain procedural and documentation requirements upon the Company
with respect to manufacturing and quality assurance activities. The FDA has
recently amended the GMP regulations. Among other things, the new regulations
will require design controls and maintenance of service records. The Company
believes that the new regulations will not substantially increase the Company's
costs of complying with GMP requirements. The Company currently has implemented
training and procedural changes with respect to the changes to these GMP
requirements.
 
     Consequences of Non-Compliance with FDA Regulations. Non-compliance with
these GMP regulations can result in, among other things, the Company and its
customers being subject to fines, limitations, civil penalties, criminal
prosecution, recall or seizure of devices, total or partial suspension of
production, failure of the government to grant premarket clearance or PMA
approval for products, withdrawal of marketing approvals, or a recommendation by
the FDA that a customer or the Company not be permitted to enter into government
contracts. The FDA also has the authority to require repair, replacement, or
refund of the cost of any device manufactured or distributed by a customer of
the Company or by the Company itself. In addition, the failure to be found in
compliance with the FDA regulations could have an adverse effect on the
Company's reputation. The FDA periodically inspects medical device manufacturers
for compliance with FDA regulations. In addition, the FDA generally inspects a
manufacturer prior to approving a PMA for a medical device. There can be no
assurance that the Company will be found in compliance with all applicable
regulations during such an inspection. The failure to be found in compliance
with the GMP regulations would result in
 
                                       40
<PAGE>   42
 
FDA enforcement action against the Company, which could result in a diminution
of the Company's reputation and an adverse effect on the Company's business.
 
     Non-FDA Regulations Within the United States. Beside the FDA regulations
described above, the Company is also subject to various state and federal
regulations with respect to such matters as safe working conditions,
manufacturing practices, environmental protection, fire hazard control, and the
disposal of hazardous or potentially hazardous materials.
 
GOVERNMENTAL REGULATIONS OUTSIDE THE UNITED STATES
 
     Sales of medical devices outside the United States are subject to
regulatory requirements that vary from country to country. The time required to
obtain approval for sale in foreign countries my be longer or shorter than that
required for FDA approval, and the requirements may differ. The export of
devices is subject to FDA regulation. In some instances, prior FDA approval is
needed. Commencing in 1998, all medical device manufacturers will be required to
obtain certifications necessary to enable the "CE Mark" to be affixed to their
products sold in the European Union. The CE Mark is a quality designation given
to products that meet certain policy directives of the European Economic Area
(an association of 15 European nations). A product designated with the CE Mark
is freely tradeable in all European Economic Area countries. In 1996, the
Company received and has maintained ISO 9001/EN 46001 certification. If a
Company customer is also ISO 9001 certified, the customer may be permitted to
affix the CE Mark to an instrument manufactured by the Company without the
customer being subject to additional requirements. In addition, all medical
device manufacturers must comply with other laws generally applicable to foreign
trade, including technology export restrictions, tariffs, and other regulatory
requirements.
 
EMPLOYEES
 
   
     As of September 30, 1997, the Company employed a total of 89 people in the
following areas:

                  TOTAL............................................    89
</TABLE>
    
 
The Company also retains 4 consulting and contract personnel in the areas of
finance, engineering, and regulation. The Company considers its labor relations
to be good, and none of its employees is covered by a collective bargaining
agreement. Currently, the local economy is growing and the unemployment rate is
low in the Salt Lake City metropolitan area, which means that the Company faces
competition to attract and retain qualified personnel. At the same time,
however, the Salt Lake City metropolitan area has a generally well-educated
workforce and is generally considered to be an attractive place to live.
Accordingly, the Company does not anticipate having difficulty in attracting and
retaining qualified personnel to meet its projected growth in the foreseeable
future.
 
FACILITIES
 
     The Company's executive offices and manufacturing facilities are located in
its new 51,000 square foot facility in Salt Lake City, Utah, which was financed
using a $2 million industrial development bond from a local municipality. The
building is situated on nearly four acres of land a few miles from the downtown
area. It allows quick access to two major interstate freeways and to the Salt
Lake International Airport. The Company believes that its current facilities are
adequate for its needs and does not anticipate any difficulty locating
additional facilities, if necessary.
 
LEGAL PROCEEDINGS
 
     The Company is not a party to any legal proceedings.

RECENT INCREASE IN COMPENSATION OF EXECUTIVE OFFICERS
 
   
     Effective January 1, 1997, the Compensation Committee approved an increase
in the salaries to $105,000 per year for each of Mr. Constantine, Mr. McNally,
and Mr. McStotts. Additionally, effective September 30, 1997, the Compensation
Committee approved the grant of Common Stock purchase options for 70,000 shares
each to Messrs. Constantine, McNally, and McStotts. The options vest over a
four-year period, and are exercisable at a price of $16.4375 per share. Lastly,
the Compensation Committee approved a new executive officer bonus plan,
commencing January 1, 1997, which provides for annual bonuses of 10% to 40% of
base salary to each officer depending on the attainment of certain annual
revenue and profit targets as a percentage of budgeted amounts. The amount of
the bonus is discretionary within certain ranges as determined by the
Compensation Committee in certain instances. Also, the Compensation Committee
has the authority to pay bonuses in excess of 40% based upon extraordinary
performance, but not to exceed 100% of base salary.
    
 
AMENDED 1993 STOCK OPTION PLAN
 
     The Company has established the Amended 1993 Stock Option Plan ("Stock
Option Plan") under which the Company may grant options to purchase up to
600,000 shares of the Company's Common Stock (subject to adjustment for such
matters as stock splits and stock dividends) to officers, directors, employees,
agents, and consultants of the Company. The purpose of the Stock Option Plan is
to provide incentives to such persons who are key to the Company's success,
thereby aligning the personal interests of such persons, through ownership of
Common Stock and other incentives, with those of the Company's shareholders.
 
     The options granted under the plan may be incentive stock options within
the meaning of section 422 of the Internal Revenue Code of 1986, as amended, or
options which do not qualify as incentive stock options. The Stock Option Plan
also provides for grant of stock appreciation rights and stock awards to
eligible participants, subject to certain forfeiture restrictions. The Stock
Option Plan may be administered by the Board of Directors of the Company or by
the Compensation Committee. The Board of Directors or the Compensation Committee
will interpret the Stock Option Plan, its rules and regulations, and the
instruments evidencing the restrictions imposed upon Common Stock sold under the
Stock Option Plan, and will make all determinations deemed necessary or
advisable for administration of the Stock Option Plan.
 
     As of September 30, 1997, options to purchase 314,190 shares of Common
Stock with a weighted average exercise price of $12.37 had been granted under
the Stock Option Plan. As of September 30, 1997, the Company had granted no
stock appreciation rights or stock awards under the Stock Option Plan. Out of
the
 
                                       46
<PAGE>   48
 
600,000 shares reserved under the Stock Option Plan, as of September 30, 1997,
241,700 shares are available for future grants.
 
PROFIT SHARING PLAN
 
   
     During 1991, the Company established a qualified 401(k) profit sharing
plan. Eligible employees may defer a portion of their salary under this plan. At
the discretion of the Board of Directors, the Company may make a contribution of
an additional amount of up to 4% of the eligible employee's salary and a
discretionary amount to be determined by the Board of Directors each year.
Employees are fully vested with respect to Company contributions after seven
years. Contributions to the plan for the nine months ended September 30, 1997
and the years ended December 31, 1996, 1995, 1994, 1993, and 1992 were $49,261,
$86,035, $77,037, $35,436, $22,981, and $34,223, respectively.
    
 
EMPLOYEE STOCK OWNERSHIP PLAN
 
   
     In 1993, the Company established and the stockholders approved the Employee
Stock Ownership Plan (ESOP). The ESOP is a defined contribution plan, and
benefits are payable under the ESOP only to the extent of Company contributions
and earnings of the ESOP. The ESOP has no minimum funding requirements and the
Company's Board of Directors has sole discretion to determine the amounts to be
contributed. Contributions by the Company will be invested primarily in Common
Stock of the Company by the trustees appointed for the ESOP or in savings
accounts, certificates of deposit, higher grade short term securities, equity
stocks, bonds, other investments, or cash. Employees are fully vested after
seven years. Contributions to the ESOP for the nine months ended September 30,
1997 and the years ended December 31, 1996, 1995, 1994, and 1993, were $0, $0,
$33,750, $0, and $16,650, respectively.

                              CERTAIN TRANSACTIONS
 
     On April 15, 1997, the Company entered into a consulting contract with DMG
Advisors, L.L.C., a Nevada limited liability corporation ("DMG"). Kirk Blosch
and Jeff W. Holmes, two of the Company's principal shareholders, are members and
managers of DMG. Under the consulting contract, the Company paid an initial fee
of $50,000 and is paying $10,000 per month through April 15, 1999 in exchange
for the consulting services of DMG in the nature of strategic planning, public
relations, advice regarding financings, and the identification and evaluation of
potential acquisitions of new products or companies. The Company is also
obligated to pay reasonable business expenses incurred by DMG.
 
     Pursuant to a Stock Purchase Agreement, dated December 1, 1996 between the
Company and Blosch & Holmes, L.L.C., a Utah limited liability company, as
amended on September 30, 1997, Blosch & Holmes has the right to appoint one
member of the Company's board of directors, provided that such nominee must be
acceptable to the Company. Kirk Blosch and Jeff W. Holmes, principal
shareholders of the Company, are the two member/managers of Blosch & Holmes. The
right to appoint a member of the Company's board of
 
                                       49

directors expires when Blosch & Holmes, together with Kirk Blosch and Jeff W.
Holmes, no longer holds at least 6.5% of the outstanding voting stock of the
Company. Blosch & Holmes has not exercised this right.
 
     For a description of the compensation arrangements between the Company and
its officers and directors, see "MANAGEMENT -- Compensation of Executive
Officers" and "-- Compensation of Directors."
 
                          DESCRIPTION OF CAPITAL STOCK
 
COMMON STOCK
 
   
     The Company is authorized to issue 5,000,000 shares of Common Stock, par
value $0.04 per share. As of September 30, 1997, there were 2,063,826 shares of
Common Stock outstanding. Holders of Common Stock are entitled to one vote per
share for the election of directors and with respect to all other matters to be
voted on by stockholders. Shares of Common Stock do not carry cumulative voting
rights and, therefore, holders of a majority of the outstanding shares of Common
Stock will be able to elect the entire Board of Directors, and if they do so,
minority shareholders would not be able to elect any members to the Board of
Directors. The Company's Board of Directors has authority, without action by the
Company's shareholders, to issue all or any portion of the authorized but
unissued shares of Common Stock, which would reduce the percentage ownership of
the Company by its existing shareholders and which may dilute the book value of
the Common Stock.
    
 
     Shareholders of the Company have no pre-emptive rights to acquire
additional shares of Common Stock. The Common Stock is not subject to redemption
and carries no subscription, sinking fund, or conversion rights. Holders of
Common Stock will be entitled to receive ratably such dividends as may be
declared by the Company's Board of Directors from time to time out of funds
legally available therefor. The Company has not paid cash dividends on its
Common Stock in the past and does not anticipate that it will pay dividends in
the foreseeable future. Additionally, the Company is restricted from declaring
any cash dividends under its current line of credit arrangement. In the event of
liquidation of the Company, the shares of the Company's Common Stock are
entitled to share equally in the corporate assets after satisfaction of all
liabilities.
 
WARRANTS
 
   
     As of September 30, 1997, the Company had outstanding warrants to acquire
500,000 shares of Common Stock. These warrants were originally granted to Blosch
& Holmes, L.L.C., a Utah limited liability company ("BH") pursuant to a Stock
Purchase Agreement entered into by the Company and BH on December 1, 1996. This
transaction closed on February 12, 1997. The transaction included the sale by
the Company of 500,000 shares of Common Stock and warrants to acquire 500,000
shares of Common Stock at $3.50 per share for a period of five years from the
date of closing. BH subsequently assigned all 500,000 of these warrants to
sixteen persons. Of these 500,000 warrants, 261,500 will be sold in this
Offering (500,000 if the Underwriters' over-allotment option is exercised in
full). See "UNDERWRITING."
    
 
STOCK OPTIONS
 
     As of September 30, 1997, the Company had outstanding options for 314,190
shares of Common Stock pursuant to the Company's Stock Option Plan at a
weighted-average exercise price of $12.37 per share. The Company has reserved
600,000 shares of Common Stock for issuance under the Stock Option Plan. Out of
these 600,000 shares, as of September 30, 1997, 241,700 shares were available
for future grants.

DELAWARE REINCORPORATION
    
 
   
     On October 23, 1997, by unanimous written consent, the Board of Directors
of the Company approved the merger of the Company into a wholly-owned subsidiary
of the Company, ZEVEX International, Inc., a Delaware corporation (hereafter,
"ZEVEX Delaware"), in order to change the Company's state of incorporation from
Nevada to Delaware (the preceding transaction is hereafter referred to as the
"Merger"). On October 23, 1997, the holders of a majority of the outstanding
shares of Common Stock of ZEVEX approved the Merger by written consent.
Additionally, the Merger has been approved by the Board of Directors and the
sole shareholder of ZEVEX Delaware as of October 23, 1997. The Company intends
to deliver an information statement to its shareholders in connection with the
Merger as required by applicable SEC regulations and anticipates that the Merger
will be consummated in November, 1997.
    
 
   
     Pursuant to the Merger, shareholders of the Company will receive one share
of ZEVEX Delaware common stock in exchange for each share of Common Stock of the
Company held by such shareholder. In addition, ZEVEX Delaware will succeed to
all of the assets and liabilities of the Company as a result of the Merger (for
convenience, the combination of ZEVEX Delaware and ZEVEX will continue to be
referred to herein as "ZEVEX" or the "Company," and the common stock of the
combined entities will continue to be referred to herein as the "Common Stock").
Certain changes in the Company's capital structure and corporate governance as a
result of the Merger are summarized below. The following summary does not
purport to be complete and is qualified by the provisions of the Company's
Certificate of Incorporation and Bylaws adopted in connection with the Merger
and by the provisions of applicable law. The Certificate of Incorporation and
Bylaws of ZEVEX Delaware are included as exhibits to the registration statement
of which this Prospectus forms a part.
    
 
   
     Common Stock. After the Merger, the Board of Directors will have the
authority to issue up to 10,000,000 shares of Common Stock, par value $0.001 per
share. Such Common Stock will have the same rights, preferences, and limitations
as before the Merger, except as described in this section below.
    
 
   
     Preferred Stock. Pursuant to the Delaware Certificate of Incorporation, the
Board of Directors will have the authority to issue up to 2,000,000 shares of
Preferred Stock, par value $0.001 per share, in one or more series and to fix
the rights, preferences, privileges, qualifications, limitations, and
restrictions thereof, and the number of shares constituting any series or the
designation of such series. The existence of unissued Preferred Stock may enable
the Board of Directors, without further action by the stockholders, to issue
such stock to persons friendly to current management or to issue such stock with
terms that could render more difficult or discourage an attempt to obtain
control of the Company by means of a merger, tender offer, proxy contest, or
otherwise, thereby protecting the continuity of the Company's management. In
addition, the issuance of Preferred Stock may also have the effect of
discouraging bids for the Company's 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. No shares of Preferred
Stock are currently outstanding and the Company has no current plans to issue
any shares of Preferred Stock.
    
 
   
     Certain Provisions of the Delaware Certificate of Incorporation and
Bylaws. Certain provisions of the Company's Certificate of Incorporation filed
with the state of Delaware (the "Certificate") and the Bylaws adopted therefrom
may have the effect of preventing, discouraging, or delaying a change in the
control of the Company and may maintain the incumbency of the Board of Directors
and management. The Certificate and Bylaws provide that the Board of Directors
shall have authority to fix the number of directors and to fill vacancies of the
Board of Directors as such vacancies occur. The Certificate and Bylaws also
provide for the Board of Directors to be classified into three classes of
directors serving staggered three-year terms. As a result, one-third of the
Board of Directors will be elected each year. Moreover, the Certificate provides
that these provisions of the Certificate relating to number, vacancies, and
classification of the Board of Directors may only be amended by a vote of at
least 66 2/3% of the shareholders. Finally, the Bylaws provide that special
meetings of the stockholders may only be called by the President of the Company
or pursuant to a resolution adopted by a majority of the Board of Directors.
    
 
   
     Certain Provisions of Delaware Law. After the Merger, the Company will be
subject to the provisions of Section 203 of the Delaware General Corporation
Law. In general, Section 203 prohibits a publicly-held
    
 
                                       51

Delaware corporation from engaging in a "business combination" with an
"interested stockholder" for a period of three years after the date of the
transaction in which the person became an interested stockholder, unless (i) the
transaction is approved by the Board of Directors prior to the date the
interested stockholder obtained such status, (ii) after consummation of the
transaction which resulted in the stockholder becoming an interested
stockholder, such stockholder owns at least 85% of the voting stock of the
Company then outstanding (exclusive of voting stock held by certain employee
stock plans and voting stock held by persons who are both directors and officers
of the Company), or (iii) on or subsequent to such date, the transaction is
approved by the Board of Directors and authorized at an annual or special
meeting of stockholders by the affirmative vote of at least 66 2/3% of the
outstanding voting stock which is not owned by the interested stockholder. For
purposes of Section 203, a "business combination" includes a merger, asset sale,
or other transaction resulting in a financial benefit to the interested
stockholder. Subject to certain exceptions, an "interested stockholder" is a
person who, together with affiliates and associates, owns, or within the
previous three years did own, 15% or more of Company's voting stock.
    
 
                        SHARES ELIGIBLE FOR FUTURE SALE
 
     Upon completion of this Offering, the Company will have 3,625,326 shares of
Common Stock outstanding (3,863,826 if the Underwriters' over-allotment option
is exercised in full). Of the outstanding shares of Common Stock, 2,292,014
(2,530,514 if the Underwriter's over-allotment option is exercised in full) will
be freely tradeable without restriction or further registration under the
Securities Act of 1933 (the "Securities Act"), unless held by "affiliates" of
the Company, as that term is defined in Rule 144 of the Securities Act
("Affiliates").
 
     The remaining 1,333,312 shares of Common Stock are "restricted securities"
within the meaning of Rule 144 under the Securities Act and were issued and sold
by the Company in private transactions and may be publicly sold only if
registered under the Securities Act or sold in accordance with an applicable
exemption from registration, such as Rule 144. Of these restricted securities,
26,202 shares are not subject to lockup agreements and will be immediately
eligible for sale in the public market following this Offering, pursuant to Rule
144(k). An additional 197,912 shares of restricted securities are not subject to
lockup agreements and will become eligible for sale in the public markets from
time to time pursuant to Rule 144.
 
   
     Certain members of the Company's Board of Directors (hereafter referred to
as the "Founders"), Kirk Blosch, Jeff W. Holmes, and Blosch & Holmes, L.L.C.
(owning the remaining 1,109,198 shares of restricted securities) have agreed,
pursuant to lockup agreements to be contained in the Underwriting Agreement in
this Offering, that they will not sell, directly or indirectly, any Common Stock
without the prior written consent of the Representatives for a period of 180
days after the closing date of this Offering. Upon the expiration of the 180 day
period, these shares will become eligible for sale in the public market subject
to the limitations for sales by Affiliates under Rule 144. The Founders also
hold vested options to purchase 37,200 shares of Common Stock at exercise prices
ranging between $3.85 and $5.00 per share pursuant to the Company's Amended 1993
Stock Option Plan (the "Stock Option Plan"). Additionally, the Founders hold
options to purchase 210,000 shares of Common Stock which become exercisable in
four equal annual installments beginning September 30, 1998 at an exercise price
of $16.4375. All of these options could be exercised and the shares received
therefrom could also be eligible for sale in the public market subject to the
limitations for sales by Affiliates under Rule 144. Notably, at some time
following this Offering, the Company may register for public sale the shares
issued pursuant to the Stock Option Plan. The Founders have included 30,000
shares of Common Stock (exclusive of the 1,109,198 shares that will be subject
to lockup agreements) owned by them in this Offering.
    
 
     On October 26, 1996, the Company paid $50,000 in cash and issued 130,000
shares of unregistered Common Stock to a non-Affiliate in exchange for 3.7 acres
of land for its new headquarters and manufacturing facility. This non-Affiliate
has agreed, pursuant to a lockup agreement, that he will not sell any of the
130,000 shares of Common Stock for a period of two years ending October 29,
1998. This individual has further agreed not to sell more than 25,000 shares of
Common Stock during any 90-day period after the expiration of the two-year
lockup period. Pursuant to Rule 144(k), this individual will not be subject to
the volume, notice, and
 
                                       52
<PAGE>   54
 
other restrictions of Rule 144, and (subject to the 90-day 25,000 shares
limitation described above), may freely sell his shares in the public markets
after the two-year lockup period.
 
     Pursuant to the Company's Stock Option Plan, certain non-Affiliate holders
of vested options to purchase 52,990 shares of Common Stock are not subject to
lockup agreements and could exercise their options and sell these shares after
one year from the date of exercise under Rule 144. The exercise prices of the
options granted and outstanding under the Stock Option Plan range from $2.50 to
$5.00. The Company has authorized 600,000 shares of Common Stock to be issued
under the Stock Option Plan. Out of these 600,000 shares, as of September 30,
1997, 241,700 shares were available for future grants. Notably, at some time
following this Offering, the Company may register for public sale the shares
issued pursuant to the Stock Option Plan.
 
     In general, under Rule 144, as currently in effect, a person (or persons
whose shares are aggregated) who has beneficially owned restricted shares for at
least one year, as well as persons who may be deemed Affiliates, will be
entitled to sell in any three-month period a number of shares that does not
exceed the greater of (i) 1% of the then outstanding shares of Common Stock or
(ii) the average weekly trading volume of the Common Stock during the four
calendar weeks immediately preceding the date on which notice of the sale is
filed with the Securities and Exchange Commission. Sales pursuant to Rule 144
are also subject to certain other requirements relating to manners of sale,
notice and availability of current public information about the Company. A
person (or person whose shares are aggregated) who is not deemed to have been an
Affiliate at any time during the three months immediately preceding the sale is
entitled to sell restricted shares pursuant to Rule 144(k) without regard to the
limitations described above, provided that two years have expired since the
later of the date on which such restricted shares were first acquired from the
Company or from an Affiliate.
 
     The Company cannot predict the effect, if any, that sales of shares of
Common Stock, or the availability of such shares for sale will have on the
market price prevailing from time to time. Sales of substantial amounts of
Common Stock in the public market could adversely affect prevailing market
prices.

this Prospectus and to certain selected dealers at such price less a concession
not in excess of $          per share, and that the Underwriters and those
dealers may reallow certain dealers, including any Underwriters, a discount not
in excess of $          per share. After the Offering, the public offering
price, concessions, and reallowance to dealers may be changed by the
Representatives.
 
     The Shares are being offered by the several Underwriters named herein
subject to prior sale, when, as and if delivered to and accepted by the
Underwriters and subject to certain other conditions. The Underwriters reserve
the right to withdraw, cancel, or modify the offer and to reject any order in
whole or in part.
 
     In connection with this Offering, the Underwriters may engage in
transactions that stabilize, maintain or otherwise affect the price of the
Common Stock. Specifically, the Underwriters may bid for and purchase shares of
Common Stock in the open market to stabilize the price of the Common Stock.
These activities may stabilize or maintain the price of the Common Stock above
independent market levels. The Underwriters are not required to engage in these
activities, and may end these activities at any time.
 
     Pursuant to the Underwriting Agreement, the Company and the Selling
Shareholders have agreed to indemnify the Underwriters against certain
liabilities that may be incurred in connection with the Offering, including
liabilities under the Securities Act, or to contribute payments that the
Underwriters may be required to make in respect thereof.
 
   
OVER-ALLOTMENT OPTION
    
 
     The Selling Security Holders have granted an option to the Underwriters,
exercisable during the 45-day period after the date of this Prospectus, to
purchase up to a maximum of 238,500 warrants for the purchase of Shares. The
Underwriters may exercise the option only to cover overallotments in the sale of
the shares that the Underwriters have agreed to purchase. To the extent that the
Underwriters exercise the option, each of the Underwriters will have a firm
commitment, subject to certain conditions, to purchase and exercise the same
percentage of the warrants as the number of shares to be purchased and offered
by such Underwriter in the above table bears to 1,591,500.
 
SELLING SHAREHOLDERS
 
     Of the 291,500 shares to be sold in the Offering on behalf of the Selling
Shareholders, 30,000 shares will be sold to the Underwriters by certain members
of the Company's management at the price of the Shares sold in the Offering
(less the Underwriter's discount and commissions described below). The
Underwriters will acquire from certain other Selling Shareholders warrants to
purchase the remaining 261,500 shares. The Underwriters will exercise the
warrants so acquired and resell all of the Shares in the Offering. The

Underwriters will pay the aggregate exercise price of the warrants to the
Company ($915,250) and will pay to the Warrant Holders the difference between
the aggregate exercise price and the aggregate sales price (less the
underwriting discount and commissions). If the Underwriters exercise in full the
over-allotment option as described below, they will acquire from certain Selling
Shareholders warrants to purchase an additional 238,500 shares. The Underwriters
will exercise these warrants and will sell the acquired Shares as part of the
Offering. The Underwriters will pay to the Company the aggregate exercise price
of these warrants ($834,750) and to the Warrant Holders the difference between

account, stock purchase warrants covering an aggregate of 100,000 shares of
Common Stock exercisable at a price equal to 120% of the public offering price

Common Stock commencing 12 months after the effective date of this Offering. The

                          INDEPENDENT AUDITORS' REPORT
 
To the Board of Directors and Stockholders
of ZEVEX International, Inc.
 
     We have audited the accompanying consolidated balance sheets of Zevex
International, Inc. and Subsidiary as of December 31, 1995 and 1994, and the
related consolidated statements of operations, stockholders' equity, and cash
flows for the years then ended. These consolidated financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these consolidated 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 consolidated financial statements are
free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the consolidated 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
Zevex International, Inc. and Subsidiary as of December 31, 1995 and 1994, and
the results of their operations and their cash flows for the years then ended in
conformity with generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
    (INFORMATION FOR THE NINE MONTHS ENDED SEPTEMBER 30, 1996 IS UNAUDITED)
 
 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Description of Business
 
     The Company was incorporated under the laws of the State of Nevada on
December 30, 1987. The Company was originally incorporated as Downey Industries,
Inc. and changed its name to ZEVEX International, Inc. on August 15, 1988. The
Company designs and manufactures advanced medical devices, including surgical
systems, device components, and sensors for medical technology companies. The
Company also designs, manufactures, and markets its own medical devices using
its proprietary technologies. The Company's design and manufacturing service
customers are medical technology companies, which sell the Company's systems and
devices under private labels or incorporate the Company's devices into their
products.
 
  Principles of Consolidation
 
     The consolidated financial statements include the accounts of ZEVEX
International, Inc. (Company) and its wholly-owned subsidiary ZEVEX, Inc. All
significant intercompany balances and transactions have been eliminated in
consolidation.
 
  Interim Financial Information
 
     The financial statements for the nine months ended September 30, 1996 and
related notes are unaudited but include all adjustments (consisting solely of
normal recurring accruals) which are, in the opinion of management, necessary
for a fair presentation of the financial position and results of operations for
the interim periods. The results of operations for the nine-month periods ended
September 30, 1996 and 1997 are not necessarily indicative of the operating
results to be expected for the full year.
 
  Reclassifications
 
     Certain prior year amounts have been reclassified to conform with the
current year presentation.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the 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
 
     The Company considers all certificates of deposit and highly liquid debt
instruments purchased with a maturity of three months or less to be cash
equivalents.
 
  Concentration of Credit Risk
 
   
     The Company's financial instruments consist primarily of cash, cash
equivalents and trade accounts receivable. Cash and cash equivalents are held in
federally insured financial institutions or invested in high grade short-term
commercial paper issued by major United States corporations. The Company sells
its products primarily to, and has trade receivables with, independent durable
medical equipment manufacturers and dealers in the United States and abroad.
During the periods presented, four of the Company's customers

    (INFORMATION FOR THE NINE MONTHS ENDED SEPTEMBER 30, 1996 IS UNAUDITED)
 
accounted for more that 10% of net product sales. (see Note 12 -- Major
Customers) Less than 10% of product sales are to foreign customers.
 
     As a general policy, collateral is not required for accounts receivable;
however, the Company periodically monitors the need for an allowance for
doubtful accounts based upon expected collections of accounts receivable and
specific identification of uncollectible accounts. Additionally, customers'
financial condition and credit worthiness are regularly evaluated. Historical
losses have not been material.
 
  Inventories
 
     Inventories are stated at the lower of cost or market; cost is determined
using the first-in, first-out method.
 
  Marketable Securities
 
     The Company's short-term investments are comprised of equity securities,
all classified as trading securities, which are carried at their fair value
based upon quoted market prices of those investments at December 31, 1996 and
September 30, 1997. Accordingly, net unrealized holding gains for the periods
ending December 31, 1996 and September 30, 1997 of $203,109 and $7,812,
respectively, are included in net income.
 
  Property and Equipment
 
   
     Property and equipment are stated at cost less accumulated depreciation.
Depreciation is provided over expected useful lives of three to twenty-five
years using the straight-line method. Leasehold improvements are amortized on a
straight-line basis over the lesser of the remaining lease term or their
estimated useful lives.
    
 
     Major replacements, which extend the useful lives of equipment, are
capitalized and depreciated over the remaining useful life. Normal maintenance
and repair items are charged to costs and expenses as incurred.
 
  Patents and Trademarks
 
   
     The costs of acquired and internally developed patents and trademarks are
amortized over the lesser of fifteen years or the estimated useful life of the
intangible asset on the straight-line basis. The Company periodically reviews
the recoverability of patents and trademarks as well as other long-term assets
and, where impairment in value has occurred, such intangibles are written down
to net realizable value.
    
 
  Income Taxes
 
     The Company provides for income taxes based on the liability method, which
requires recognition of deferred tax assets and liabilities based on differences
between financial reporting and tax bases of assets and liabilities measured
using enacted tax rates and laws that are expected to be in effect when the
differences are expected to reverse.
 
  Stock Options
 
   
     The Company has elected to follow Accounting Principles Board Opinion No.
25, Accounting for Stock Issued to Employees(APB 25) and related Interpretations
in accounting for its employee stock options rather than adopting the
alternative fair value accounting provided for under Statement of Financial
Accounting Standard (SFAS) No. 123, Accounting for Stock-based Compensation.
Under APB 25, because the exercise price of the Company's stock options equals
the market price of the underlying stock on the date of grant, no compensation
expense is recognized.

    (INFORMATION FOR THE NINE MONTHS ENDED SEPTEMBER 30, 1996 IS UNAUDITED)
 
  Revenue Recognition
 
   
     The Company records revenue from the sale of manufactured products upon
shipment. Revenue from contracts to perform engineering design and product
development services are generally recognized as milestones are achieved and
costs are expensed as incurred.
    
 
  Advertising Costs
 
     Advertising costs are expensed during the year in which they are incurred.
Advertising expenses were $39,027, $39,237, $113,566, $78,961 and $64,832,
respectively for the years ended December 31, 1994, 1995 and 1996 and the nine
months ended September 30, 1996 and 1997.
 
  Net Income (Loss) Per Common Share
 
     Primary earnings (loss) per common share is calculated by dividing net
income (loss) for the period by the weighted average number of the Company's
common shares outstanding and dilutive common equivalent shares from stock
options and warrants, as calculated using the treasury stock method. The
treasury stock method requires calculating commons stock equivalents using the
average stock price for the period.
 
     Fully diluted earnings (loss) per common share reflect the calculation of
the number of common equivalent shares based on the stock price at the end of
the period. Fully diluted per common share amounts were not reported in 1995 and
1996 because the difference was not material from primary earnings per common
share. The fully diluted earnings per common share was $.17 for the nine months
ended September 30, 1997. The weighted average number of common shares
outstanding used in the fully diluted calculation was 2,390,186.
 
   
     All shares held in the Company's Employee Stock Ownership Plan (ESOP) are
considered outstanding for both primary and fully diluted earnings per share
calculations. All share and per share data is stated to reflect a 20 percent
stock dividend declared by the Board of Directors in March 1995 (see Note 9 --
Stockholders' Equity).
    
 
  New Accounting Pronouncements
 
     In 1997 the FASB issued SFAS No. 128, Earnings Per Share, SFAS No. 130,
Reporting Comprehensive Income, and SFAS No. 131, Disclosures about Segments of
an Enterprise and Related Information. As of September 30, 1997, these standards
were either not effective or not yet adopted by the Company. The Company
believes the new standards will not have a material impact on the Company's
consolidated financial statements presented herein or in the future.

 5. INCOME TAXES
 
     The (provision) benefit for income taxes is made, at Federal and State
statutory rates, based on earnings reported in the financial statements for the
amount of income taxes payable currently.
 
     Deferred taxes are classified as current or non-current, depending on the
classification of the assets and liabilities to which they relate. Deferred
taxes arising from temporary differences that are not related to an asset or
liability are classified as current or non-current depending on the periods in
which the temporary differences are expected to reverse.
 
     Temporary differences giving rise to the deferred tax liability consist
primarily of the excess of depreciation for tax purposes over the amount
recorded for financial reporting purposes and unrealized gains on marketable
securities being reported differently for financial reporting and tax purposes.

 6. BANK LINE OF CREDIT
    
 
   
     On September 29, 1996, the Company renewed its line of credit arrangement
with a financial institution for which total indebtedness may not exceed
$3,024,658. The line matures on May 31, 1998. The line of credit is
collateralized by accounts receivable, inventory and property and equipment and
bears interest at a rate of prime plus 1%; 9.25% and 9.50% at December 31, 1996
and September 30, 1997, respectively. The Company owes $700,000 on the line of
credit at September 30, 1997. Under the current line of credit agreement, the

 8. EMPLOYEE BENEFIT PLANS
    
 
  401(k) Profit Sharing Plan
 
   
     During 1991, the Company established a qualified 401(k) profit sharing plan
covering substantially all employees. Eligible employees may defer a portion of
their salary. At the discretion of the Board of Directors, the Company may make
a contribution of an additional amount of up to four percent (4%) of the
eligible employees' salary and a discretionary amount to be determined each year
by the Board of Directors. Employees are fully vested after seven years.
Contributions to the plan for the year ended December 31, 1994, 1995 and 1996
were $35,436, $77,037 and $86,035, respectively, and $36,866 and $49,261 for the
nine months ended September 30, 1996 and 1997, respectively. The Company shows a
payable to the plan of $9,718, $38,000, and $12,606 at December 31, 1995 and
1996, and September 30, 1997 respectively.
    
 
  Employees' Stock Ownership Plan
 
     Effective October 14, 1993, the Company adopted an Employee Stock Ownership
Plan, that covers all employees who are over the age of 21, have been employed
for at least 90 days and who provide at least 1,000 hours of service.
 
     Full vesting will occur after seven years of service or upon normal
retirement at 65 years of age. Contributions to the plan are at the discretion
of the Board of Directors with no minimum annual funding requirements.
Contributions to the plan primarily will be made with common stock of the
Company.
 
   
     The Company had previously made a contribution to the plan for the year
ended December 31, 1995 of 9,500 shares with a cost of $33,750. No contribution
was made for the year ended December 31, 1994 and 1996 or for the nine months
ended September 30, 1997.
    
 
 9. STOCKHOLDERS' EQUITY
 
  Stock Dividend
 
   
     On March 8, 1995, the Company declared a 20% stock dividend payable on
April 3, 1995 to all stockholders of record on March 23, 1995.
    
 
  Issuance of Common Stock
 
     On November 29, 1996, the Company paid cash of $50,000 and issued 130,000
shares of the Company's common stock for the purchase of 3.7 acres of land in
Murray, Utah for the purpose of constructing a manufacturing facility.
 
     On February 12, 1997, the Company completed a private placement offering
for $1,250,000 of its securities, which consist of 500,000 units at a price of
$2.50 per unit. Each unit consists of one share of common stock and a warrant to
purchase one share of common stock at a price of $3.50 per share. The issued
shares and shares underlying the warrants are entitled to registration rights
for a period of five years from completion of the offering.
 
  Repurchase of Common Stock Units
 
   
     The Company previously repurchased 13,440 shares of outstanding common
stock for $50,400. The Company subsequently in 1993 and 1995 contributed all
13,440 shares to the Employee's Stock Ownership Plan (see Note 8 -- Employees'
Stock Ownership Plan).

  Warrants
 
     The Company issued a warrant to purchase 24,000 shares of common stock at
$7.50 per share pursuant to a public offering of the Company's common stock in
1993. This warrant expires May 7, 1998. The shares underlying this warrant are
entitled to registration rights. On September 30, 1997, the warrant was
exercised and the warrant holders waived their registration rights.
 
     In February 1997, the Company issued 500,000 warrants in connection with a
$1,250,000 private placement offering, as discussed above.
 
  Common Stock Reserved for Future Issuance
 
   
     At September 30, 1997, the Company had reserved 1,055,890 shares of common
stock for future issuance, including 500,000 shares reserved for exercise of
warrants and 555,890 shares reserved under the Company's stock option plan.
    
 
   
  Stock Option Plan
    
 
   
     In September 1997, the Board of Directors consolidated its previous three
stock option plans into one plan and established the Amended 1993 Stock Option
Plan (the "Stock Option Plan"). There are currently 600,000 shares of common
stock authorized for issuance under the Stock Option Plan, subject to adjustment
for such matters as stock splits and stock dividends.
    
 
   
     The Stock Option Plan provides for the grant of incentive stock options,
stock appreciation rights and stock awards to eligible participants and may be
administered by the Board of Directors or by the Compensation Committee.
    
 
     On September 30, 1997, the Company granted a total of 210,000 options with
an exercise price of $16.44 to three officers/directors. The options vest
ratably over a four year period from the grant date.
 
   
     All options granted under the Stock Option Plan expire after five to seven
years from the grant date and become exercisable no later than four years from
the grant date.

</TABLE>
    
 
     The weighted average fair value of options granted in the year ended
December 31, 1996 and for the nine months ended September 30, 1997, were $1.33
and $9.98 (none in 1995). At December 31, 1996 and September 30, 1997, 86,100
and 104,190 shares, respectively, were exercisable.
 
     Pro forma information regarding net income and earnings per share is
required by SFAS No. 123, and has been determined as if the Company had
accounted for its employee stock options under the fair value method. The fair
value of these options was estimated at the date of grant using the
Black-Scholes option pricing model with the following weighted average
assumptions for 1996 and 1997, respectively: risk-free interest rate of 6.1% and
5.9%, dividend yield of 0%; volatility factors of the expected market price of
the Company's common stock of .40 and .90; and a weighted-average expected life
of the option of 3 years and 4 years.
 
     The Black-Scholes option valuation model was developed for use in
estimating the fair value of traded options which have no vesting restrictions
and are fully transferable. In addition, option valuation models require the
input of highly subjective assumptions including the expected stock price
volatility. Because the Company's employee stock options have characteristics
different from those of traded options, and because changes in the subjective
input assumptions can materially affect the fair value estimate, in management's
opinion, the existing models do not necessarily provide a reliable single
measure of the fair value of its employee stock options.
 
     For purposes of pro forma disclosures, the estimated fair value of the
options is amortized over the options' vesting period. Because the effect of
SFAS No. 123 is prospective, the initial impact on pro forma net income (loss)
may not be representative of compensation expense in future years. The effect on
the Company's pro forma results for each of the fiscal years 1995 and 1996 was
not material (less than $.01 per share). For the nine months ended September 30,
1997, pro forma net income and pro forma net income per common share were
$246,434 and $.11, respectively.

     Additionally, SFAS No. 123 requires that companies with wide ranges between
the high and low exercise prices of its stock options segregate the exercise
prices into ranges that are meaningful for assessing the timing and number of
additional shares that may be issued and the cash that may be received as a
result of the option exercises. Below are the segregated ranges of exercise
prices as of September 30, 1997:

10. LEASE COMMITMENTS
 
   
     In 1996 the Company and its subsidiary occupied an administrative and
manufacturing facility under the terms of an operating lease agreement. In June
1997 the Company moved into a new facility owned by and constructed for the
Company.
    
 
   
     Lease expense of $54,508, $74,551, $109,505, $76,181 and $55,558 has been
charged to operations for the years ended December 31, 1994, 1995 and 1996 and
nine months ended September 30, 1996 and 1997, respectively. The lease expired
in April 1997.
    
 
   
     Future minimum lease payments required under non-cancelable operating
leases at December 31, 1996 were $30,698 (none at September 30, 1997).
    
 
11. FAIR VALUE OF FINANCIAL INSTRUMENTS
 
     The following methods and assumptions were used by the Company in
estimating its fair value disclosures for financial instruments:
 
          Cash and cash equivalents: The carrying amount reported in the balance
     sheet for cash and cash equivalents approximates its fair value.
 
          Marketable securities: The Company determines fair values based on
     quoted market values.
 
   
          Industrial development bond: The fair values of the Company's
     long-term debt are estimated using discounted cash flow analyses, based on
     the Company's current incremental borrowing rates for similar types of
     borrowing arrangements. Due to the recent issuance of the Industrial
     Development Revenue Bond, the estimated fair value approximates the
     carrying amount.
    
 
     The carrying amounts and fair values of the Company's financial instruments
are as follows:

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
NEVADA LAW
 
     Section 78.037 of the Nevada Revised Statutes ("NRS") provides, in general,
that a corporation may eliminate or limit, with certain exceptions, the
liability of officers and directors to the corporation or its shareholders for
damages for breach of fiduciary duty as an officer or director.
 
   
     NRS Section 78.751(1) provides, in general, that a corporation may
indemnify an officer or director who is a party to a proceeding if the officer
or director's conduct was in good faith and not opposed to the corporation's
best interests, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful. NRS Section 78.751(3)
provides, in general, that a corporation must indemnify an officer or director
for his expenses in connection with the defense of any proceeding if the
director has been successful, on the merits or otherwise. NRS Section 78.751(5)
provides, in general, that a corporation may advance expenses to an officer or
director who is made a party to a criminal or civil proceeding before a final
disposition is made, if the corporation receives an undertaking by or on behalf
of the officer or director to repay any amounts advanced if it is determined by
a court that such officer or director is not entitled to indemnification. NRS
Section 78.751(6) provides, in general, that the indemnification provisions of
Section 78.751 continue for a person who has ceased to be an officer or
director, and inures to the benefit of the heirs, executors, and administrators
of such person. NRS Section 78.752 provides, in general, that a corporation may
purchase and maintain insurance, or may make other financial arrangements on
behalf of officers and directors, among others, against liabilities imposed on
them by reason of actions in their official capacity or arising from service
performed on behalf of the corporation.
    
 
ARTICLES OF INCORPORATION
 
   
     Article Three of the Company's Articles of Incorporation provides, in
general, that the Company shall indemnify, purchase and maintain insurance, or
make other financial arrangements on behalf of officers and directors, to the
fullest extent permitted under NRS Sections 78.751 and 78.752, as described in
the preceding section. Article Eleven of the Company's Articles of Incorporation
provides, in general, that except for acts or omissions involving intentional
misconduct, fraud, or a known improper payment of dividends, no officer or
    
 
                                      II-1
<PAGE>   79
 
director shall be personally liable to the Company or to the shareholders of the
Company for breach of such officer's or director's fiduciary duty.
 
BYLAWS
 
     Article Five, Section (1)(b) of the Company's Bylaws provides, in general,
that the Company shall indemnify, to the fullest extent permitted in Article
Three of the Company's Articles of Incorporation, any officer or director who is
a party to a proceeding if the officer or director's conduct was in good faith
and not opposed to the corporation's best interests, and, with respect to any
criminal action or proceeding, had no reasonable cause to believe his conduct
was unlawful.
 
     Article Five, Section (1)(d) of the Company's Bylaws provides, in general,
that the Company must indemnify an officer or director for his actual and
reasonable expenses in connection with the defense of any proceeding if the
officer or director has been successful, on the merits or otherwise. Article
Five, Section (1)(e) provides, in general, that any indemnification by the
Company must be approved on a case-by-case basis by a majority of a quorum of
directors who are not parties to such proceeding, a written opinion from
independent legal counsel to the Company, a majority vote at a duly held meeting
of a quorum of disinterested shares, a majority written consent of outstanding
disinterested shares, or upon application to the court in such proceeding
against the officer or director.
 
     Article Five, Section (1)(f) of the Company's Bylaws provides, in general,
that the Company may advance expenses to an officer or director who is made a
party to a criminal or civil proceeding before a final disposition is made, if
the Company receives an undertaking by or on behalf of the officer or director
to repay any amounts advanced unless it is determined by a court that such
officer or director is entitled to indemnification. Article Five, Section (1)(g)
provides, in general, that the indemnification provisions of Article Five,
Section (1) shall continue for a person who has ceased to be an officer or
director, and inures to the benefit of the heirs, executors, and administrators
of such person. Article Five, Section (2) provides, in general, that the Company
may purchase and maintain insurance, or may make other financial arrangements on
behalf of officers or directors to the fullest extent provided in Article Three
of the Company's Articles of Incorporation.
 
   
REINCORPORATION IN DELAWARE
    
 
   
     On October 23, 1997, by unanimous written consent, the Board of Directors
of the Company approved the merger of the Company into a wholly-owned subsidiary
of the Company, ZEVEX International, Inc., a Delaware corporation (hereafter,
"ZEVEX Delaware"), in order to change the Company's state of incorporation from
Nevada to Delaware (the preceding transaction is hereafter referred to as the
"Merger"). The Merger has been approved by the Company's shareholders and by the
Board of Directors and sole shareholder of ZEVEX Delaware as of October 23,
1997. The Company anticipates that the Merger will be consummated in November,
1997. See "DESCRIPTION OF CAPITAL STOCK -- Delaware Reincorporation" in the
Prospectus. Because the surviving entity of the Merger will be subject to
different statutory, charter, and internal governance provisions, certain
indemnification provisions relating to the Delaware General Corporate Law
("DGCL"), the Certificate of Incorporation filed in Delaware, and the Bylaws
adopted in connection therewith are described below.
    
 
   
DELAWARE LAW
    
 
   
     Section 102(b)(7) of the DGCL allows a corporation to eliminate or limit
the personal liability of a director to the corporation or its shareholders for
monetary damages for breach of fiduciary duty as a director except for: (i) any
breach of the duty of loyalty to the corporation or its stockholders; (ii) acts
or omissions not in good faith or which involve intentional misconduct or a
knowing violation of law; (iii) declaration of unlawful dividends or unlawful
stock repurchases or redemptions; (iv) any transaction from which the director
derived an improper personal benefit; or (v) any act or omission occurring prior
to the date any such provision eliminating or limiting such liability became
effective.
    
 
                                      II-2
<PAGE>   80
 
   
     Section 145(a) of the DGCL provides that a corporation may indemnify an
officer or director who is or is threatened to be made a party to a proceeding
(other than an action by or in the right of the corporation) by reason of the
fact that such officer or director is or was (i) serving as an officer,
director, employee, or agent of the corporation, or (ii) served at the request
of such corporation as a director, officer, employee, or agent of another
corporation or other enterprise or entity. Such indemnification may only be made
if the officer or director's conduct was in good faith and in a manner such
person reasonably believed to be in or not opposed to the corporation's best
interest, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe that his conduct was unlawful. Section 145(c) of the
DGCL provides that a corporation shall indemnify an officer or director for his
reasonable expenses in connection with the defense of any proceeding if the
officer or director has been successful, on the merits or otherwise. Section
145(e) provides that a corporation may advance expenses to an officer or
director who is made a party to a criminal or civil proceeding before a final
disposition is made, if the corporation receives an undertaking by or on behalf
of such officer or director to repay any amounts advanced if it is determined
that such officer or director is not entitled to indemnification. Section 145(j)
provides that the indemnification provisions of Section 145 continue for a
person who has ceased to be an officer or director, and inures to the benefit of
the heirs, executors, and administrators of such person. Section 145(g) provides
that a corporation may purchase and maintain insurance on behalf of officers or
directors, among others, against liabilities imposed upon them by reason of
actions in their capacities as such, and whether or not the corporation would
have the power to indemnify them against such liability under Section 145.
    
 
   
DELAWARE CERTIFICATE OF INCORPORATION
    
 
   
     Article VII of the Certificate of Incorporation provides that the liability
of directors to the Company or its stockholders is eliminated to the fullest
extent permitted under the DGCL, as described in the preceding section.
    
 
   
BYLAWS OF ZEVEX DELAWARE
    
 
   
     Article VI, Section 6.1(a) of the Bylaws of ZEVEX Delaware provides that an
officer or director who was or is made party to, or is threatened to made a
party to, or is involved in any proceeding by reason of the fact that he or she
is or was an officer or director, or is or was serving at the request of the
corporation as a director, officer, employee, or agent of another corporation,
or as its representative in another enterprise shall be indemnified and held
harmless to the fullest extent permitted and subject to the standards of
conduct, procedures and other requirements under Delaware law. Article VI,
Section 6.1(a) further provides that ZEVEX Delaware may purchase and maintain
insurance on behalf of an officer or director against any liability arising out
of their status as such, whether or not the corporation would have the power to
indemnify such officer or director.
    
 
   
     Article VI, Section 6.1(b) of the Bylaws provides that the right of an
officer or director to indemnification shall continue beyond termination as such
and inures to the benefit of the heirs and personal representatives of such
officer or director.
    
 
   
     Article VI, Section 6.1(d) of the Bylaws provides that ZEVEX Delaware
shall, from time to time, reimburse or advance to an officer or director the
funds necessary for payment of expenses incurred in connection with defending
any proceeding for which he or she is indemnified by the corporation, in advance
of the final disposition of such proceeding, provided that, if then required by
the DGCL, such advancements may only be paid upon receipt by the corporation of
an undertaking by or on behalf of such officer or director to repay any such
amount so advanced if it is ultimately determined by a final and unappealable
judicial decision that the officer or director is not entitled to be indemnified
for such expenses.
    
 
ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES
 
   
     On September 30, 1997, the Company sold and issued 24,000 shares of Common
Stock to three individuals in connection with the exercise of warrants
originally issued to Wilson-Davis & Co. on May 7,
    
 
                                      II-3
<PAGE>   81
 
   
1993. The Company believes that the transaction was exempt from the registration
provisions of the Securities Act pursuant to Section 4(2) of such Act.
    
 
     On February 12, 1997, in consideration for $1,250,000, the Company sold and
issued 500,000 shares of Common Stock together with warrants for 500,000 shares
of Common Stock to Blosch & Holmes, L.L.C., a Utah limited liability company. No
underwriting discounts or commissions were given or paid in connection with the
transaction. The warrants and shares were subsequently assigned to 16
individuals. All of the aforementioned purchasers represented to the
satisfaction of the Company that they qualify as "accredited investors" as that
term is defined under the Securities Act of 1933 (the "Securities Act"). The
Company believes that the transaction was exempt from the registration
provisions of the Securities Act pursuant to Section 4(2) of such Act and Rule
506 promulgated thereunder.
 
   
     On October 29, 1996, the Company sold and issued 130,000 shares of Common
Stock together with $50,000 cash to an individual in exchange for 3.7 acres of
certain real property valued at approximately $505,000. The property, which now
serves as the site for the Company's headquarters and manufacturing facility,
was conveyed to the Company by a General Warranty Deed dated December 29, 1996.
The Company believes that the transaction was exempt from the registration
provisions of the Securities Act pursuant to Section 4(2) of such Act.
    
 
     Since July 1, 1997, a few employees of the Company have exercised options
to purchase Common Stock of the Company under the Company's Stock Option Plan.
The exercise prices of the options ranged from $0.79 to $5.00 per share. The
shares of Common Stock issued under the Stock Option Plan have not been
registered under the Securities Act. As of September 30, 1997, the total number
of shares of Common Stock issued pursuant to such exercises is 44,110. The
Company believes that the aforementioned transactions are exempt from
registration under Section 3(b) of the Securities Act and Rule 505 promulgated
thereunder.

ITEM 17. UNDERTAKINGS
 
     Insofar as indemnification for liabilities arising under the Securities Act
of 1933, as amended, may be permitted to directors, officers, and controlling
persons of the registrant pursuant to any 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 a 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 this registration statement in reliance upon Rule 430A and contained in
     a form of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or
     (4) or 497(h) under the Securities Act shall be deemed to be part of this
     Registration Statement as of the time it was declared effective.
 
          (2) For the purpose of determining any liability under the Securities
     Act of 1933, each post-effective amendment that contains a new form of
     prospectus shall be deemed to be a new registration statement relating to
     the securities offered therein, and the offering of such securities at that
     time shall be deemed to be the initial bona fide offering thereof.

<PAGE>   83
 
                               POWER OF ATTORNEY
 
     Each person whose signature appears below hereby designates and appoints
Dean G. Constantine and Phillip L. McStotts and each of them, as his/her
attorneys-in-fact (the "Attorneys-in-Fact") with full power to act alone, and to

amendments) to this Registration Statement, which amendments may make such
changes in this Registration Statement as the Attorneys-in-Fact, or either of
them, deem appropriate, including any post-effective amendments, as well as any
related registration statement (or amendment thereto) filed in reliance upon
Rule 462(b) under the Securities Act of 1933, and to file each such amendment to
this Registration Statement, together with all exhibits thereto and any and all
documents in connection therewith with the U.S. Securities and Exchange
Commission, hereby granting unto said Attorneys-in-Fact and agents, and each of

                                 ARTICLE I. NAME

     The name of the corporation is ZEVEX INTERNATIONAL, INC. (the
"Corporation").

                          ARTICLE II. REGISTERED OFFICE

     The address of the Corporation's registered office in the State of Delaware
is Corporation Trust Center, 1209 Orange Street, in the City of Wilmington, in
the County of New Castle, in the State of Delaware. The name of the registered
agent at such address is the Corporation Trust Company.

                              ARTICLE III. PURPOSE

     The purpose of the Corporation is to engage in any lawful act or activity
for which corporations may be organized under the General Corporation Law of
Delaware.

                            ARTICLE IV. CAPITAL STOCK

     The Corporation is authorized to issue two classes of shares to be
designated, respectively, "Preferred Stock" and "Common Stock." The number of
shares of Preferred Stock authorized to be issued is Two Million (2,000,000).
 The number of shares of Common Stock authorized to be issued is Ten Million
(10,000,000). The Preferred Stock and the Common Stock shall each have a par
value of $0.001 per share.

     (a)  Provisions Relating to the Common Stock.

          Each holder of Common Stock is entitled to one vote for each share of
Common Stock standing in such holder's name on the records of the Corporation on
each matter submitted to a vote of the stockholders, except as otherwise
required by law.

     (b) Provisions Relating to the Preferred Stock. The Board of Directors (the
"Board") is authorized, subject to limitations prescribed by law and the
provisions of this Article IV, to provide for the issuance of the shares of
Preferred Stock in accordance with Sections 102(a) and 151(a) of the General
Corporation Law of Delaware, in one or more series, and by filing a certificate
pursuant to the applicable law of the State of Delaware, to establish from time
to time the number of shares to be included in each such series, and to fix the
designation, powers, preferences and rights of the shares of each such series
and the qualifications, limitations or restrictions thereof.

                          ARTICLE V. BOARD OF DIRECTORS


<PAGE>   2

     (a) Number. The number of directors constituting the entire Board shall be
as fixed from time to time by vote of a majority of the entire Board, provided,
however, that the number of directors shall not be reduced so as to shorten the
term of any director at the time in office.

     (b) Classified Board. The Board shall be divided into three classes, as
nearly equal in numbers as the then total number of directors constituting the
entire Board permits with the term of office of one class expiring each year. At
the first annual meeting of the stockholders, directors of the first class will
be elected to hold office for a term expiring at the next succeeding annual
meeting, directors of the second class will be elected to hold office for a term
expiring at the second succeeding annual meeting, and directors of the third
class will be elected to hold office for a term expiring at the third succeeding
annual meeting.

     (c) Vacancies. Vacancies on the Board shall be filled by the affirmative
vote of the majority of the remaining directors, though less than a quorum of
the Board, or by election at an annual meeting or at a special meeting of the
stockholders called for that purpose.

     (d) Initial Directors. The initial Board shall consist of the following
persons:

               Dean G. Constantine

                               ARTICLE VI. BYLAWS

     In furtherance and not in limitation of the powers conferred by statute,
the Board is expressly authorized to make, alter, amend or repeal the By-Laws of
the Corporation.

                               ARTICLE VII. LIABILITY

     To the fullest extent permitted by the Delaware General Corporation Law as
the same exists or as may hereafter be amended, no director of the Corporation
shall be personally liable to the Corporation or its stockholders for or with
respect to any acts or omissions in the performance of his or her duties as a
director of the Corporation. Any amendment or repeal of this Article VII will
not eliminate or reduce the affect of any right or protection of a director of
the Corporation existing immediately prior to such amendment or repeal.

                    ARTICLE VIII. SPECIAL VOTING REQUIREMENTS

     The following actions, when submitted to the stockholders of the
Corporation for their consideration, shall require the affirmative vote of at
least 66 2/3% of the outstanding Common Stock of the Corporation: amendment of


<PAGE>   3
Sections (a), (b), or (c) of Article V of the Certificate of Incorporation. The
foregoing voting requirements shall not otherwise be deemed to affect the voting
rights granted by this Certificate of Incorporation, the Bylaws, or the Delaware
General Corporation Law, to the Board.

                                     BYLAWS

                                       OF

                            ZEVEX INTERNATIONAL, INC.

                                    ARTICLE I

                                  SHAREHOLDERS

     SECTION 1.1. ANNUAL MEETINGS. An annual meeting of shareholders shall be
held for the election of directors on such date, and at such time and place as
the Board of Directors may, from time to time, determine. Any other proper
business may be transacted at an annual meeting. If the annual meeting is not
held on the date designated, it may be held as soon thereafter as convenient and
shall be called the annual meeting.

     SECTION 1.2. SPECIAL MEETINGS. Special meetings of the shareholders, for
any purpose or purposes, unless otherwise prescribed by the General Corporation
Law of the State of Delaware, may be called by the President or the Board of
Directors. The shareholders do not have the authority to call a special meeting
of the shareholders.

     SECTION 1.3.  SHAREHOLDER PROPOSALS/NOMINEES.

          a. Shareholder Proposals. Shareholders seeking to place shareholder
proposals on the agenda for a shareholders' meeting must (i) notify the
Corporation of such proposal not less than 30 nor more than 60 days prior to the
date of the meeting; provided, however, that if the Corporation provides
shareholders with less than 40 days advance notice of the date of the meeting,
the shareholder notice must be given no later than the close of business on the
10th day following the day the Corporation's notice was mailed or publicly
disclosed. Such notice must provide the Corporation with adequate information
regarding the proposal.

          b. Shareholder Director Nominees. Shareholders director nominations
must (i) be in writing and contain adequate information about the nominee; and
(ii) be received by the secretary of the Corporation not less than 30 nor more
than 60 days prior to the date of the meeting at which Directors will be
elected; provided, however, that if the Corporation provides shareholders with
less than 40 days advance notice of the date of the meeting, the shareholder
notice must be given no later than the close of business on the 10th day
following the day 

<PAGE>   2
the Corporation's notice was mailed or publicly disclosed.

     SECTION 1.4. NOTICE OF MEETINGS. Whenever shareholders are required or
permitted to take any action at a meeting, a written notice of the meeting will
be given that states the place, date, and hour of the meeting, and in the case
of a special meeting, the purpose(s) for which the meeting is called. Unless
otherwise provided by law, the Certificate of Incorporation, or these Bylaws,
the written notice of any meeting will be given not less than ten nor more than
sixty days before the date of the meeting to each shareholder entitled to vote
at such meeting. If mailed, such notice will be deemed to be given when
deposited in the United States mail, postage prepaid, directed to the
shareholder at his or her address as it appears in the records of the
Corporation.

     SECTION 1.5.  WAIVER OF NOTICE.  A shareholder may waive notice of any
meeting; provided that a shareholder's attendance at a meeting shall constitute
waiver of notice of such meeting, except when the shareholder attends a meeting
for the express purpose of objecting to the transaction of any business to be
transacted at the meeting, and not for the purpose of objecting to the purpose
of the meeting.

     SECTION 1.6. ADJOURNMENTS. Any meeting of shareholders, annual or special,
may adjourn from time to time to reconvene at the same or some other place, and
notice need not be given of any such adjourned meeting if the time and place are
announced at the meeting at which the adjournment is taken. At the adjourned
meeting, the Corporation may transact any business that might have been
transacted at the original meeting. If the adjournment is for more than thirty
days, or if after the adjournment a new record date is fixed for the adjourned
meeting, pursuant to Section 1.3, notice of the adjourned meeting will be given
to each shareholder of record entitled to vote at the meeting.

     SECTION 1.7.  RECORD DATE.

          a.  Determination of Record Date.
              ----------------------------
For purposes of determining the number and identity of shareholders for any
purpose, the Board of Directors may fix a date in advance as the record date for
any such determination of shareholders, provided that the record date may not
precede the date of the resolution fixing the record date. The record date may
not be more than sixty days prior to the date that the particular action
requiring the determination of shareholders is to occur. If to determine the
shareholders entitled to notice of, or to vote at, a meeting of shareholders,
the record date may not be fewer than ten days prior to the meeting. The record
date for determining shareholders for any other purpose shall be at the close of

<PAGE>   3


business on the day on which the Board of Directors adopts the resolution
relating thereto. A determination of shareholders of record entitled to notice
of, or to vote at, a meeting of shareholders will apply to any adjournment of
the meeting; provided that the Board of Directors may fix a new record date for
the adjourned meeting.

          b.  Failure to Fix Record Date.
              --------------------------
If the stock transfer books are not closed and no record date is fixed for the
determination of shareholders entitled to notice or to vote, or to receive
payment of a dividend, the date on which the notice is mailed or the Board of
Directors resolution declaring the dividend is adopted, as the case may be, will
be the record date for such determination of shareholders.

     SECTION 1.8. LIST OF SHAREHOLDERS ENTITLED TO VOTE. At least ten days
before each meeting of shareholders, the officer or agent charged with
overseeing the stock transfer books of the Corporation will compile a complete
list of the shareholders entitled to vote at such meeting, or any adjournment
thereof, arranged in alphabetical order, with the address of and the number of
shares held by each. Such list will be kept on file at the Corporation's
principal office for the ten days before the meeting and will be subject to the
inspection of any shareholder during that ten day period during normal business
hours for any purpose related to the meeting and during the meeting.

     SECTION 1.9. QUORUM. Except as otherwise provided by law, the Certificate
of Incorporation, or these Bylaws, a majority of the outstanding shares of the
Corporation entitled to vote, represented in person or by proxy, will constitute
a quorum at a meeting of shareholders. If less than a majority of the
outstanding shares are represented at the meeting, a majority of the shares so
represented may adjourn the meeting from time to time without further notice. If
a quorum is present or represented at such adjourned meeting, any business may
be transacted that might have been transacted at the meeting as originally
notified. The shareholders present at a duly organized meeting may continue to
transact business until adjournment, notwithstanding the withdrawal of enough
shareholders to leave less than a quorum.

     SECTION 1.10.  VOTING.

         a.  One Vote Per Share.
             ------------------
Unless otherwise provided by the Certificate of Incorporation (or action of the
Board of Directors as provided therein) or these Bylaws, each outstanding share
entitled to vote will be entitled to one vote on each matter submitted to a vote

<PAGE>   4


at a meeting of shareholders.

         b.  Required Vote.
             -------------
Article VIII of the Certificate of Incorporation provides for super-majority
voting in certain circumstances. Except as set forth therein, or as provided in
the General Corporation Law of the State of Delaware, a majority vote of those
shares present and voting at a duly organized meeting will suffice to defeat or
enact any proposal; provided that with respect to votes to elect directors, a
plurality of the votes cast will be sufficient to elect.

         c. Shares Held By Other Than the Record Owner.
             ------------------------------------------ 

Shares held by an administrator, executor, guardian, or conservator may be voted
by him or her, in person or by proxy, without the transfer of such shares into
his or her name. Shares held in the name of a trustee may be voted by him or
her, in person or by proxy, only if the shares are transferred into the
trustee's name. Shares held in the name of, by or under the control of a
receiver may be voted by the receiver without transferring the shares into the
receiver's name if authority to do so is evidenced in an order from the court
that appointed the receiver. A shareholder whose shares are pledged shall be
entitled to vote his or her shares until the shares are transferred into the
name of the pledgee, and thereafter, the pledgee will be entitled to vote the
shares so transferred. Shares belonging to the Corporation or held by it in a
fiduciary capacity may not be voted, directly or indirectly, at any meeting, and
will not be counted in determining the total number of outstanding shares at any
given time.

     SECTION 1.11.  PROXIES.

         a.  General.
             -------
At all meetings of shareholders, a shareholder may vote by proxy. Proxies must
be written, signed by the shareholder or by his or her duly authorized attorney
in-fact, and filed with the Secretary of the Corporation before or at the time
of a meeting where a proxy is granted. No proxy is valid after six months from
the date of its execution, unless otherwise provided in the proxy or such proxy
is coupled with an interest.

         b.  Irrevocable Proxies.
             -------------------
A proxy may be irrevocable if it states that it is irrevocable and if, and only
as long as, it is coupled with an interest sufficient in law to support an
irrevocable power.


<PAGE>   5


         c. Revocation of a Proxy.
             ---------------------
A shareholder may revoke any proxy that is not irrevocable by attending the
meeting and voting in person or by filing an instrument in writing revoking the
proxy or by delivering a proxy in accordance with applicable law bearing a later
date to the Secretary of the Corporation.

     Section 1.12.  SHAREHOLDER ACTION BY WRITTEN CONSENT WITHOUT A MEETING.

          a.  Action.
              ------
Any action required to be taken at any annual or special meeting of shareholders
of the Corporation, or any action that may be taken at any annual or special
meeting of such shareholders may be taken without a meeting, without prior
notice, and without a vote, if a consent in writing, setting forth the action so
taken, is signed by the holders of outstanding stock having not less than the
minimum number of votes that would be necessary to authorize or take such action
at a meeting at which all shares entitled to vote thereon were present and
voted.

          b.  Notice.
              ------
Prompt notice of the taking of the corporate action without a meeting by less
than unanimous written consent shall be given to those shareholders who have not
consented in writing. If the action which is consented to is such as would have
required the filing of a certificate under any Section of the General
Corporation Law of Delaware, if such action had been voted on by shareholders at
a meeting thereof, then the certificate filed under such Section shall state, in
lieu of any statement required by such Section concerning any vote of
shareholders, that written notice and written consent have been given as
provided in Section 228 of the General Corporation Law of Delaware.

                                   ARTICLE II

                               Board of Directors

     SECTION 2.1. NUMBER, QUALIFICATIONS. The Board of Directors shall consist
of that number of directors as are set from time to time by the affirmative vote
of a majority of the members of the Board of Directors. The Board of Directors
shall be divided into three classes, with only a single class subject to
re-election in a given year. Subject to Section 2.2, below, a director will hold
office until the next annual meeting of shareholders at which his or her class
is subject to re-election and until his or her successor is elected and


<PAGE>   6

qualified. Directors need not be shareholders of the corporation.

     SECTION 2.2. ELECTION; RESIGNATION; VACANCIES. The Board of Directors will
initially consist of the persons named as directors in the Certificate of
Incorporation, and each director so elected will hold office until the first
annual meeting of shareholders and until his or her successor is elected and
qualified. At the first annual meeting of shareholders, the shareholders will
elect directors to serve in all three classes of the Board of Directors as
provided by the Certificate of Incorporation. Thereafter, one class of directors
will be elected each year at either an annual or special meeting of the
shareholders to hold office for the period of time designated for that class. If
there is only one nominee for any directorship, it will be in order to move
that the Secretary cast the elective ballot to elect the nominee. A director may
resign at any time on written notice to the Corporation. Any vacancy occurring
in the Board of Directors, whether by reason of death, resignation, removal, or
an increase in the number of directors, may be filled by the affirmative vote of
the majority of the remaining directors, though less than a quorum of the Board
of Directors, or by election at an annual meeting or at a special meeting of the
shareholders called for that purpose. A director elected to fill a vacancy will
be elected for the unexpired term of his predecessor in office.

     SECTION 2.3. REGULAR MEETINGS. A regular meeting of the Board of Directors
for the election of officers and the transaction of any other business that may
properly come before the meeting shall be held immediately after, and at the
same place as, each annual meeting of shareholders, if a quorum of directors is
then present or as soon thereafter as may be convenient. Regular meetings of the
Board of Directors may be held at such places within or without the State of
Delaware and at such times as the Board of Directors may from time to time
determine. The Board of Directors may provide, by resolution, the date, time,
and place for the holding of additional regular meetings without other notice
than such resolution.

     SECTION 2.4. SPECIAL MEETINGS. Special meetings of the Board of Directors
may be called by or at the request of the President or any director. The
person(s) authorized to call special meetings of the Board of Directors may fix
any place, within or without the State of Delaware, to hold a special meeting of
the Board of Directors. Notice of a special meeting must be given to each
director by the person(s) calling the meeting at least two days before the
meeting.

     SECTION 2.5. WAIVER OF NOTICE. A director may waive notice of any meeting.

A director's attendance at a meeting shall constitute waiver of notice of such
meeting; provided that, when a director attends a meeting for the express
purpose 

<PAGE>   7

of objecting to the transaction of any business to be transacted at the
meeting, the director will not be deemed to have waived notice of such meeting.

     SECTION 2.6. TELEPHONIC MEETINGS PERMITTED. Members of the Board of
Directors, or any committee designated by the Board of Directors, may
participate in a meeting thereof by means of telephonic conference, or similar
communications equipment that permits all persons participating in the meeting
to hear each other, and participation in a meeting pursuant to this Bylaw will
constitute presence at such meeting.

     SECTION 2.7. QUORUM. Vote Required for Action. At all meetings of the
Board of Directors, a majority of the whole Board of Directors will constitute a
quorum for the transaction of business. Unless required by the General
Corporation Law of the State of Delaware, the Certificate of Incorporation or
these Bylaws, the vote of a majority of the directors present at a meeting at
which a quorum is present will be the act of the Board of Directors. If less
than a majority is present at a meeting, a majority of the directors present may
adjourn the meeting from time to time without further notice. Once a quorum has
been established at a duly organized meeting, the Board of Directors may
continue to transact corporate business until adjournment, notwithstanding the
withdrawal of enough members to leave less than a quorum.

     SECTION 2.8. PAYMENT OF EXPENSES. By resolution of the Board of Directors,
directors may be paid their expenses, if any, of attendance at each meeting of
the Board of Directors. Directors may be paid also either a fixed sum for
attendance at each meeting of the Board of Directors or a stated salary as
director. Such payment will not preclude any director from serving the
Corporation in any other capacity and receiving compensation therefor.

     SECTION 2.9. DISSENT TO CORPORATE ACTION. A director who is present at a
meeting of the Board of Directors at which action on any corporate matter is
taken shall be presumed to have assented to the action taken unless he or she
(i) enters his or her dissent in the minutes of the meeting, (ii) files written
dissent to such action with the Secretary of the meeting before adjournment, or
(iii) expresses such dissent by written notice to the Secretary of the
Corporation within one (1) day after the adjournment of the meeting. The right
to dissent shall not apply to a director who voted in favor of such action.

     SECTION 2.10. ACTION BY WRITTEN CONSENT. Any action required or permitted
to be taken at a meeting of the Board of Directors may be taken without a
meeting if all members of the Board of Directors sign a written consent with
respect to such action. Such consent shall be filed with the minutes of
proceedings of the Board of Directors.

members thereof present at any meeting and not disqualified from voting, whether

Board of Directors to act at the meeting in place of any such absent or
disqualified member. Any such committee, to the extent permitted by the General
Corporation Law of the State of Delaware and to the extent provided in the

affairs of the Corporation, and may authorize the seal of the Corporation to be

                    Indemnification of Directors and Officers

     SECTION 6.1.  DIRECTORS.

          a.  Right to Indemnification Insurance.
              ----------------------------------
Every person who was or is a party to, or is threatened to be made a party to,
or is involved in any action, suit or proceeding, whether civil, criminal,
administrative or investigative, by reason of the fact that he or she, or a
person of whom he is the legal representative, is or was a director or officer,
or is or was serving at the request of the corporation as a director, officer,
employee or agent of another corporation, or as its representative in another
enterprise (an "Indemnitee"), shall be indemnified and held harmless by the
Corporation to the fullest extent legally permissible under the laws of the
State of Delaware against all judgments, fines, penalties, excise taxes, amounts
paid in settlement and costs, charges and expenses (including attorneys' fees
and disbursements) actually and reasonably incurred or suffered by him or her in
connection therewith, subject to the standards of conduct, the procedures, and
other applicable provisions of the General Corporation Law of the State of
Delaware. Such right of indemnification is a contract right which may be
enforced in any manner desired by such person. The Corporation may purchase and
maintain insurance on behalf of an Indemnitee against any liability arising out
of such status, whether or not the corporation would have the power to indemnify
such 

<PAGE>   11


person.

          b.  Inurement.
              ---------
The right to indemnification shall inure whether or not the claim asserted is
based on matters that predate the adoption of this Article VI, will continue as
to an Indemnitee who has ceased to hold the position by virtue of which he or
she was entitled to indemnification, and will inure to the benefit of his or her
heirs and personal representatives.

          c.  Non-exclusivity of Rights.
              -------------------------
The right to indemnification and to the advancement of expenses conferred by
this Section 6.1 are not exclusive of any other rights that an Indemnitee may
have or acquire under any statute, bylaw, agreement, vote of shareholders or
disinterested directors, this Certificate of Incorporation or otherwise.

          d.  Advancement of Expenses.
              -----------------------
The Corporation shall, from time to time, reimburse or advance to any Indemnitee
the funds necessary for payment of expenses, including attorneys' fees and
disbursements, incurred in connection with defending any proceeding for which he
or she is indemnified by the Corporation, in advance of the final disposition of
such proceeding; provided that, if then required by the General Corporation Law
of the State of Delaware, the expenses incurred by or on behalf of an Indemnitee
may be paid in advance of the final disposition of a proceedings only upon
receipt by the Corporation of an undertaking by or on behalf of such Indemnitee
to repay any such amount so advanced if it is ultimately determined by a final
and unappealable judicial decision that the Indemnitee is not entitled to be
indemnified for such expenses.

     SECTION 6.2. OFFICERS, EMPLOYEES AND AGENTS. The Board of Directors may, on
behalf of the Corporation, grant indemnification to any officer, employee, agent
or other individual to such extent and in such manner as the Board of Directors
in its sole discretion may from time to time and at any time determine, in
accordance with the General Corporation Law of the State of Delaware.

maintained at Bank and the minimum balance to be maintained in each. The
Borrower will designate which Operating Account or Consolidation Account will
be used for depositing advances under this Line of Credit.

        E.      Borrower authorizes Bank during each Business Day to transfer
Borrower's funds among and between the designated Operating Account, a
Consolidation Account established by Bank, if applicable, an Investment
Management Account (established by separate agreement) and this Line of Credit,
without any further written or oral authorization from Borrower, in accordance
with the following procedures:

                (1)  Each regular banking day, Bank will withdraw all collected
        funds (as defined by Bank's existing funds availability policy) in the
        Operating Accounts and deposit the same in the Consolidation Account (if
        used), or in the Operating Account used for disbursement purposes if no
        Consolidation Account is designated. All funds so consolidated shall be
        applied in the following priority:

                        (i)  First: Bank shall pay all checks and charges drawn
                or incurred on Borrower's designated Operating Accounts,
                including checks drawn for the purpose of accessing funds
                available under this Line of Credit and further including wire
                transfers, cash advances and charges pre-authorized by Borrower.

                        (ii)  Second: Bank shall deposit into each Operating
                Account the minimum balance described above the signatures to
                this Agreement.

                        (iii)  Third: Any excess funds shall be applied to the
                outstanding principal due on this Line of Credit.

                        (iv)  Fourth: Any remaining funds shall be deposited to
                Borrower's Investment Management Account to be invested in
                accordance with the terms of the agreement establishing the
                Investment Management Account. All interest earned on the
                Investment Management Account shall inure to the benefit of the
                Borrower.


                                      -6-

        F.      If sufficient collected funds are not available in the
Consolidation Account or Operating Account to provide for the requirements of
the first and second priorities described above, then funds sufficient to pay
the checks and charges and any overdrafts and to maintain the minimum balances
required, if any, shall be advanced first from the available balance in
Borrower's Investment Management Account and second from the Line of Credit. If
sufficient collected funds are still not available, Bank shall not be required
to satisfy the first and second priorities described above.

        G.      Every transaction contemplated herein is complete and binding
upon all parties hereto at such time as the Bank records the transaction on its
records.

        H.      The parties authorized to act for Borrower under this Agreement
shall be those parties specifically described herein as Authorized Agents or as
may be authorized to transact business or issue checks or other pre-authorized
charges on the Borrower's Operating Accounts or the Investment Management
Account.

        I.      All principal payments on this Line of Credit shall be made at
Borrower's discretion through appropriate deposits to one or more of the
Operating Accounts.

        J.      Bank, in its sole discretion, may make the transfers described
herein based upon the deposit of uncollected funds and any such transfers or
disbursements shall be reversed at the time of the receipt of any returned item.

        K.      Loan Interest Rate. Borrower shall pay to Bank interest on the
outstanding principal balance of all Advances obtained under the Line of Credit.
The interest rate shall be the Loan Interest Rate. The Loan Interest Rate may
change from time to time and the interest payable on the outstanding principal
balance will fluctuate with changes in the Loan Interest Rate. Interest shall be
computed daily on the basis of a 360 day year and charged on the number of
actual days Advances are outstanding.

        L.      Interest Payments. Bank will bill Borrower each month for
interest due for the preceding month on total outstanding Advances from the Line
of Credit. Interest will be due in arrears and the interest due must be paid to
Bank on the due date shown on each billing statement. If payment is not received
within ten (10) Business Days after the due date shown on the billing statement,
Borrower authorizes Bank to charge the Line of Credit for the amount of the
interest due for the preceding month so long as such charge does not cause the
outstanding principal balance to exceed


                                      -7-
<PAGE>   8

the Line of Credit Limit or the Borrowing Base, whichever is less. Bank, in
failing to render an interest statement, does not waive its right to receive or
collect interest payments.

        M.      Principal Payments. Until Bank declares a termination of the
Line of Credit following the occurrence and during the continuance of an Event
of Default, or otherwise notifies Borrower in writing, Borrower may make
payments on the principal balance of Advances outstanding on the Line of Credit
in amounts and at such times as Borrower, in its sole discretion, determines.
There shall be no pre-payment penalty. Principal payments may be paid directly
to Bank or pursuant to one or more deposits made to the Operating Account.

        N.      Compliance with Borrowing Base. If at any time during the term
of this Agreement, the Borrower obtains knowledge that the total principal
amount of all Advances outstanding exceeds the Line of Credit Limit or the
Borrowing Base whichever is less, the Borrower shall immediately reduce the
principal amount of the Advances outstanding at that time by an amount equal to
such excess.

        O.      Origination Fee. At the time of closing this Agreement,
Borrower shall pay to Bank a loan origination fee of $500.00. All other fees
and costs of documenting this Agreement, including attorney's fees, will be
paid for by Borrower at the time of closing.

        P.      Other Fees. Borrower shall pay to Bank a reasonable fee,
including outside attorneys' fees, to amend the Loan Agreement or any of the
Loan Documents. A reasonable fee may also be charged for Bank's review of any
request by the Borrower to modify or waive any restrictive covenants. A fee
charged to modify or waive a restrictive covenant does not imply that Bank
consented to the modification or waiver, but is only to reimburse Bank for its
time and effort in reviewing the request by Borrower. Bank shall issue a
statement for these fees. If the fees are not paid by the 15th day of the
following month, Borrower directs Bank to add the amount to the principal
balance of the Loan. Failing to render a statement does not waive the right to
receive or collect these fees.

        Q.      Initial Disbursement. The initial disbursement shall be used to
payoff the principal balance and terminate Borrower's existing line of credit
with Bank.

        5.      COLLATERAL.

                                      -8-

        A.      The Collateral for all Advances made to Borrower under the Line

limited to Accounts, contract rights, chattel paper, instruments, general
intangibles, choses in action, furniture, fixtures and equipment now owned or
hereafter acquired and as further described in a Security Agreement or other
lien instrument executed at any time prior to or in connection with this
Agreement. In enforcing the terms of any Security Agreement, following
Borrower's default, Bank shall not be required to liquidate the Collateral in
any particular order. The Collateral is provided in consideration of the
availability of funds under this Agreement, and no security interest shall be
released or be deemed released until this Agreement has been terminated and all
amounts Advanced have been paid in full. No junior Lien on any of Bank's
Collateral shall affect the priority of any Advance made to Borrower under this
Agreement.

        B.      Borrower agrees that any and all Collateral given to secure
Borrower's obligations and indebtedness under this Agreement shall also secure
any and all liabilities and obligations of Borrower to Bank existing now or in
the future (including that certain Reimbursement Agreement in the initial amount
of $2,024,658 dated on or about October 1, 1996, whether for the payment of

Person and assigned endorsed to Bank and whether several, joint, or joint and

at any time by furnishing Bank with a written notice that this Agreement is
terminated and coincidentally therewith paying all Advances, including
interest, fees and charges, outstanding under the Line of Credit.

        B.      Termination by Bank. In the event of Borrower's Default, and
following notice and failure by Borrower to cure as required herein, Bank may
terminate its obligation to make further Advances under this Agreement.
Borrower's default is not waived by any action of Bank other than by a written
waiver of Default.

        7.      MATURITY.

        Notwithstanding any provision herein to the contrary, all outstanding
Advances together with accrued and unpaid interest,



                                      -9-

fees and charges shall mature and be due and payable in full May 31, 1998.

        8.      PLEDGE.

        Borrower does hereby pledge to Bank and grant to Bank a security
interest, perfected by possession, on all of Borrower's accounts, credits,
assets or things of value that from time to time are in the possession and/or
control of Bank. In the event of Default, as defined herein, and Borrower's
failure to cure the Default, Bank may exercise its rights under the pledge and
apply the pledged property to the outstanding balance of Advances due to Bank.

Agreement.

                              CONTINUING GUARANTY
TO: BANK ONE, UTAH, NA

        1. For valuable consideration, the undersigned (hereinafter called
"Guarantor") jointly and severally with Borrower and any other guarantor(s),
unconditionally guarantees payment and promises to pay to BANK ONE, UTAH,
NATIONAL ASSOCIATION (hereinafter called "Bank"), or order, on demand, in
lawful money of the United States, any and all indebtedness of _________________
       ZEVEX, INC.
- -------------------------------------------------------------------------------
(hereinafter called "Borrower") to Bank. The word "Indebtedness" is used herein
in its most comprehensive sense and includes any and all advances, debts,
obligations, interest, and liabilities of Borrower, and any and all contracts,
letters of credit or commitments of Bank made for the benefit or at the request
of Guarantor or Borrower, or any one or more of them, heretofore, now or
hereafter made, incurred or created, whether voluntary or involuntary, and
however arising whether due or not due, absolute or contingent, liquidated or
unliquidated, determined or undetermined, and whether Borrower may be liable
individually or jointly with others, or whether recovery upon such indebtedness
may be, or hereafter becomes, barred by any statute of limitations, or whether
such indebtedness may be, or hereafter becomes, otherwise unenforceable.

        2. The liability of Guarantor for Borrower's Indebtedness shall not
exceed at any one time the total of the guaranteed principal sum of 
 THREE MILLION TWENTY FOUR THOUSAND SIX HUNDRED FIFTY EIGHT DOLLARS AND NO/100
- --------------------------------------------------------------------------------
($3,024,658.00) Dollars plus all accrued and accruing interest upon such
guaranteed principal sum to the same extent such interest is contracted and
agreed by Borrower, plus all of Bank's costs, expenses and attorney's fees
incurred in connection with or relating to the collection or enforcement of
this Guaranty. This Guaranty shall bind and obligate the undersigned, his
heirs, devisees, personal representatives, successors and assigns, with
Borrower, jointly and severally, for the payment of the Indebtedness precisely
as if the same had been contracted and was due and owing by him in person. The
obligations hereunder are joint and several and independent of the
obligations of Borrower or any other Guarantor and a separate action or actions
may be brought and prosecuted against Guarantor whether action is brought
against Borrower or whether Borrower be joined in any such action or actions;
and Guarantor waives the benefit of any statute of limitations or any other
statute affecting his ability hereunder or the enforcement thereof. Guarantor
further waives any action against the Borrower or Guarantor required by any
statute. Guarantor submits himself to the jurisdiction of the District Court of
Salt Lake County, State of Utah, and agrees that the laws of the State of Utah
shall govern this agreement.

        3. Guarantor authorizes Bank, without notice or demand and without
affecting his liability hereunder, to (a) renew, compromise, extend, revise,
accelerate or otherwise change the time for payment of, or otherwise change
the terms of, the Indebtedness or any part thereof, including increase or
decrease of the rate of interest thereon, before and after any revocation of
this Guaranty; (b) take and hold security for the payment of this Guaranty or
the Indebtedness guaranteed; (c) exchange, enforce, waive and release any such
security; (d) take additional security; (e) apply such security and direct the
order or manner of sale thereof as Bank, in its discretion, may determine; and
(f) release or substitute any one or more of the endorsers or guarantors or
acquire additional guarantors. Bank may, without notice, assign this Guaranty
in whole or in part.

        4. Guarantor waives any right to require Bank to (a) proceed against
Borrower or other guarantors; (b) proceed against or exhaust any security held
from Borrower or Guarantor; or (c) pursue any other remedy in Bank's power
whatsoever. Guarantor waives any defense arising by reason of any disability
or other defense of Borrower or by reason of the cessation, from any cause
whatsoever, of the liability of Borrower. Until all Indebtedness of Borrower to
Bank shall have been paid in full, even though such Indebtedness is in excess
of Guarantor's liability hereunder, Guarantor shall have no right of subrogation
unless Bank, at its option, so elects, and Guarantor hereby waives any right to
enforce any remedy which Bank now has, or may hereafter have, against
Borrower, and hereby waives any benefit of, and any right to participate in,
any security now or hereafter held by Bank. Guarantor waives all presentments,
demands for performance, notices of non-performance, protests, notices of
protest, notices of dishonor and notices of acceptance of this Guaranty and of
the existence, creation, or incurring of new or additional Indebtedness.

        5. Guarantor also hereby waives any claim, right or remedy which such
Guarantor may now have or hereafter acquire against Borrower that arises
hereunder and/or from the performance by any Guarantor hereunder including,
without limitation, and claim, remedy or right of subrogation, reimbursement,
exoneration, contribution, indemnification, or participation in any claim,
right or remedy of Bank against the Borrower or any security which Bank now has
or hereafter acquires, whether or not such claim, right or remedy arises in
equity, under contract, by statute, under common law or otherwise.

        6. If any payment received by the Bank from the Borrower in respect of
the indebtedness is subsequently recovered from or repaid by the Bank as the
result of any bankruptcy, dissolution, reorganization, arrangement, or
liquidation proceedings (or proceedings similar thereto), the Guarantor's
payment obligation hereunder shall be reinstated and shall continue to be
effective as though such payment had not been made. The provisions of this
Section shall survive termination of this Guaranty.

        7. This Guaranty is continuing in nature and no written revocation
hereof received by Bank shall affect in any manner rights arising under this
Guaranty with respect to (a) liabilities which shall have been created,
contracted, assumed or incurred prior to actual receipt by the Bank of written
notice of such revocation; (b) liabilities which shall have been created,
contracted, assumed or incurred after actual receipt by Bank of such written
notice pursuant to any contract, letter of credit or commitment entered into
by the Bank prior to receipt of such notice, or (c) any of the aforementioned
liabilities arising out of or in any way related to the Indebtedness, which
shall have been renewed, modified, extended, consolidated, amended or revised
after revocation of this Guaranty, any or all of which actions are contemplated
and hereby permitted by Guarantor, and this Guaranty shall continue in full
force and effect, and Bank shall have the rights herein provided for, as if no
such revocation had
<PAGE>   28
occurred. The sole effect of revocation hereof shall be to exclude from this
Guaranty liabilities and Indebtedness thereafter arising which are unconnected
with liabilities and Indebtedness theretofore arising and existing. Any such
revocation of this Guaranty at any time by one or more other guarantors shall
not affect the liability hereunder of Guarantor as to any Indebtedness of the
Borrower, but this Guaranty shall in all respects remain in force and effect as
to such Indebtedness and transactions. The death of any Guarantor shall not
operate as a revocation of liability hereunder of the estate of any such
Guarantor until actual receipt by Bank of written notice of the death of such
Guarantor. Any such revocation by written notice of death shall have the same
effect as any other written revocation hereunder. Guarantor waives notice of
revocation given by any other Guarantor or Guarantors. Any payment by Guarantor
shall not reduce his maximum obligation hereunder, unless written notice to
that effect be actually received by Bank at, or prior to, the time of such
payment. Revocation of this Guaranty shall not in any way affect the rights,
duties, obligations or liabilities of either Bank or Guarantor hereunder with
respect to transactions occurring or Indebtedness incurred prior to the
effectiveness of such revocation.

     8.   In addition to all liens upon, and the right of set-off against, the
monies, securities or other property of Guarantor given to Bank by law, Bank
shall have a lien upon, and a right of set-off against, to the extent permitted
by law, all monies, securities and other property of Guarantor now or hereafter
in the possession of or on deposit with Bank, whether held for safekeeping or
otherwise; and every such lien and right of set-off may be exercised without
demand upon, or notice to, Guarantor. No lien or right of set-off shall be
deemed to have been waived by any act or conduct on the part of Bank, or by any
neglect to exercise such right of set-off, or to enforce such lien, or by any
delay in so doing, and every right of set-off and lien shall continue in full
force and effect until such right of set-off or lien is specifically waived or
released by an instrument in writing executed by Bank.

     9.   Guarantor agrees to pay upon demand all of Bank's costs and expenses,
including reasonable attorneys' fees and legal expenses, incurred in
connection with the enforcement of this Guaranty. Costs and expenses include
Bank's reasonable attorneys' fees and legal expenses whether or not the
attorney is a salaried employee of Bank and whether or not there is a lawsuit,
including reasonable attorneys' fees and legal expenses for bankruptcy or
insolvency proceedings, appeals, and any anticipated post-judgment collection
services. Guarantor also shall pay all court costs and such additional fees as
may be directed by the court.

     10.  Guarantor represents and warrants to Bank that (a) no representations
or agreements of any kind have been made to Guarantor which would limit or
qualify in any way the terms of this Guaranty; (b) this Guaranty is executed at
Borrower's request and not at the request of Bank; (c) Bank has made no
representation to Guarantor as to the creditworthiness of Borrower; and, (d)
upon Bank's request, Guarantor will provide to Bank financial and credit
information in a form acceptable to Bank.

     11.  This Guaranty is exclusive and cumulative as to amounts and shall not
serve to revoke or alter any Guaranty previously delivered to Bank nor (unless
otherwise specifically provided in writing at the date and execution thereof) be
revoked by any Guaranty subsequently delivered to Bank. This Guaranty does not
in any manner whatsoever limit the amount of any borrowing heretofore or
hereafter made under any other financing agreement between Bank and Borrower.

     12.  Bank shall not be deemed to have waived any rights under this
Guaranty unless such waiver is given in writing and signed by Bank. No delay or
omission on the part of Bank in exercising any right shall operate as a waiver
of such right or any other right. A waiver by Bank of a provision of this
Guaranty shall not prejudice or constitute a waiver of Bank's right otherwise
to demand strict compliance with any other provision of this Guaranty. No prior
waiver by Bank, nor any course of dealing between Bank and Guarantor, shall
constitute a waiver of any of Bank's rights or of any of Guarantor's
obligations as to any future transactions. Whenever the consent of Bank is
required under this Guaranty, the granting of such consent by Bank in any
instance shall not constitute continuing consent to subsequent instances where
such consent is required and in all cases such consent may be granted or
withheld at the sole discretion of Bank.

     13.  In all cases where there is but a single Guarantor, all words used
herein in the plural shall be deemed to have been used in the singular where
the context and construction so require; and when there is more than one
Borrower named herein, the word "Borrower" shall mean all and any one or more
of them; and any reference to "his" shall also include "her" or "its" where
appropriate. 
 
     14.  This Agreement is a final expression of the agreement between the
Guarantor and Bank and this written agreement may not be contradicted by
evidence of any alleged oral agreement.

     15.  Guarantor authorizes all financial institutions and credit reporting
agencies to furnish Bank opinions and credit information on or affecting
Guarantor, and Guarantor authorizes Bank to report opinions and credit
information affecting Guarantor to all credit reporting agencies or other
financial institutions.

     IN WITNESS WHEREOF, the undersigned Guarantor has executed this Guaranty
this 29th day of September, 1997.

                             ARBITRATION AGREEMENT

        A.      Binding Arbitration. The undersigned hereby agree that all
controversies and claims of any nature arising directly or indirectly out of any
and all loan transactions between or among them and any related agreements,
instruments or documents, and including but not limited to a claim based on or
arising from an alleged tort, shall at the written request of any party be
arbitrated pursuant to the applicable Commercial Arbitration Rules of the
American Arbitration Association ("AAA"). The arbitration shall occur in Salt
Lake City, Utah. Judgment upon any award rendered by the arbitrator(s) may be
entered in any court having jurisdiction. The Federal Arbitration Act shall
apply to the construction and interpretation of this arbitration agreement.

        B.      Arbitration Panel. A single arbitrator shall have the power to
render a maximum award of one hundred thousand dollars ($100,000). A single
arbitrator shall be knowledgeable in the subject matter of the dispute. When any
party files a claim in excess of this amount, the arbitration decision shall be
made by the majority vote of three (3) arbitrators selected as provided herein.
No arbitrator shall have the power to restrain any act of any party.

        If arbitration hereunder is required to be before a three (3) person
panel of neutral arbitrators, the panel shall consist of one (1) person from
each of the following categories:

                (1)     An attorney who has practiced in the area of commercial
        law for at least ten (10) years or a retired judge at the State or
        Federal District Court or Appellate Court level;

                (2)     A person with at least ten (10) years experience in
        commercial lending; and,

                (3)     A person with at least ten (10) years experience in
        the borrower's industry.

The AAA shall submit a list of persons meeting the criteria outlined above for
each category of arbitrator, and the parties shall select one (1) person from
each category in the manner established by the AAA.

        The arbitrator(s) shall award costs and expenses of the arbitration
proceeding in accordance with the provisions of the loan agreement, promissory
note and/or other loan documents relating to the credit which is the subject of
the arbitrated claim or dispute.

<PAGE>   30
        C.      Provisional Remedies, Self-Help and Foreclosure. No provision
of paragraph A shall limit the right of any party to exercise self help
remedies, to foreclose against any real or personal property collateral, or to
obtain any provisions or ancillary remedies (including but not limited to
injunctive relief or the appointment of a receiver) from a court of competent
jurisdiction. At Bank's option, it may enforce its rights under a mortgage by
judicial foreclosure, and under a deed of trust either by exercise of power of
sale or by judicial foreclosure. The institution and maintenance of any remedy
permitted above shall not constitute a waiver of the right to submit any
controversy or claim to arbitration. The statute of limitations, estoppel,
waiver, laches, and similar doctrines which would otherwise be applicable in an
action brought by a party shall be applicable in any arbitration proceeding.

        Agreed to this 29th day of September, 1997.

                            ZEVEX INTERNATIONAL INC.

         ZEVEX INTERNATIONAL, INC., a Nevada corporation (the "Company"), hereby
adopts this Amended 1993 Stock Option Plan of ZEVEX INTERNATIONAL, INC. (the
"Plan"), which amends and restates the 1993 Incentive Stock Option Plan adopted

stock, and/or stock appreciation rights may be granted from time to time to
directors and employees of the Company or its subsidiaries, or others who

         1. Purpose of the Plan. The Plan is intended to aid the Company in

and/or directors of the Company, to use their best efforts to promote the
success of the Company's business and to provide them with an opportunity to
obtain or increase a proprietary interest in the Company. It is also designed to
permit the Company to reward those individuals who are not employees or
directors of the Company but who are perceived by management as having
contributed to the success of the Company or who are important to the continued
business and operations of the Company. The above aims will be effectuated
through the granting of shares of common stock of the Company (the "Stock"),
options ("Options") to purchase shares of the Company's Stock on a favorable
basis, and/or stock appreciation or other rights ("SAR's"), subject to the terms
and conditions of this Plan. It is intended that the Options issued pursuant to
this Plan include, where designated as such at the time of grant, options which
qualify as Incentive Stock Options within the meaning of 422 of the Internal
Revenue Code or any amendment or successor provision thereto ("Incentive
Options"). Further, all stock options issued by the Company under the Company's
1991 Stock Option Plan and the 1996 Non-employee Director's Stock Option Plan
(collectively, the "Prior Plans") shall be subject to the terms of the Plan, and
the Prior Plans shall become of no further force and effect upon the written
consent of each remaining holder of options or other rights issued under the
Prior Plans.

         2. Administration of the Plan.

         The Plan shall be administered by the Company's Board of Directors (the
"Board") or, in whole or in part, by a committee designated by the Board (the
"Administrator"). Such committee (the "Committee") shall consist of not less
than two (2) persons, all of whom shall be "nonemployee directors" as that term
is defined in Rule 16b-3 promulgated under the Securities Exchange Act of 1934,
as amended (the "Exchange Act"). Subject to the foregoing, the Board may remove
or add members to the Committee and the Board or the remaining members of the
Committee shall fill any vacancies that occur. Additionally, the Board may at
any time terminate the functions of the Committee and reassume all powers and
authority previously delegated to the Committee. Any director or officer of the
Company may from time to time make recommendations to the Board or Committee
with respect to individuals to be considered for an award under the Plan and the
nature 


<PAGE>   2

and amount of such award. Any award approved by the Board or Committee shall be
approved by a majority vote of those members of the Board or Committee, as the
case may be, in attendance at a meeting at which a quorum is present or, if the
award under consideration is to a member of the Board or Committee, by a
majority vote of the members of the Board or Committee in attendance at a
meeting at which a quorum is present who are disinterested with respect to the
award under consideration.

         The interpretation and construction of the terms of the Plan or any
award under the Plan by the Committee or the Board shall be final and binding on
all participants in the Plan absent a showing of demonstrable error. No member
of the Board or Committee shall be liable for any action taken or determination
made in good faith with respect to the Plan or any award.

         3. Shares of Stock Subject to the Plan. A total of 600,000 shares of
Stock may be subject to or issued under awards granted pursuant to the terms of
this Plan. Any shares subject to an Option or other right under the Plan, which
Option or right for any reason expires or is terminated, or is surrendered
unexercised as to such shares, may be reserved for issuance pursuant to future
awards under the Plan. If any right to acquire Stock granted under the Plan is
exercised by the delivery of shares of Stock or the relinquishment of rights to
shares of Stock, only the net shares of Stock issued (the shares of Stock issued
less the shares of Stock surrendered) shall count against the total number of
shares reserved for issuance under the terms of this Plan.

         4. Reservation of Stock on Granting of Option. At the time of granting
any Option or other right to acquire Stock under the terms of this Plan, there
will be reserved for issuance on the exercise of the Option or right the number
of shares of Stock of the Company subject to such Option or right. The Company
may reserve either authorized but unissued shares or issued shares that have
been reacquired by the Company.

         5. Eligibility. Awards under the Plan may be granted to directors,
officers, and other employees of the Company or its subsidiaries, as may be
existing from time to time, and to other individuals as may be deemed in the
best interest of the Company by the Board or Committee. Such awards shall be in
the amounts, and shall have the rights and be subject to the restrictions, which
are determined by the Board or the Committee in accordance with the provisions
of this Plan.

         6. Term of Award and Certain limitations on Right to Exercise Award.

                  (a) Each award shall have the term established by the Board or
         Committee at the time the award is granted.

                  (b) The term of the award, once it is granted, may be reduced
         only as provided for in this Plan or in the terms of the award.

                  (c) Unless otherwise specifically provided by the written
         terms of the award, no holder or his legal representatives, legatees,
         or distributees, will be, or shall be deemed to be, a holder of any
         shares subject to an award unless and until the holder exercises his
         right to acquire Stock and delivers the required consideration to the
         Company in accordance with the 


<PAGE>   3

terms of this Plan and the provisions of the award. Unless otherwise
specifically provided by the written terms of the award, no adjustment shall be
made for dividends or other rights for which the record date is prior to the
date such Stock is acquired by the holder.

                  (d) Awards under the Plan shall vest at such time or times and
         on such terms as the Board or Committee may determine at the time of
         the grant of the award.

                  (e) If any award is granted to a directors, officer or
         employee of the Company and such individual is terminated or resigns
         from the Company within six (6) months of such award, the unexercised
         portion of the award shall be null and void, and such individual shall
         have no further rights thereunder as of the date of such termination or
         resignation.

                  (f) Awards granted under the Plan shall contain such other
         provisions as the Board or Committee shall deem advisable, including
         without limitation (i) further restrictions on the exercise of the
         award, (ii) provisions regarding exercise of awards following
         termination or death different that provided in Sections 15 and 16, and
         (iii) provisions regarding the acceleration of vesting of awards upon
         the occurrence of certain events.

                  (g) In no event may an award be exercised after the expiration
         of its term.

         7. Payment of Exercise Price. The exercise of any award shall be
contingent on receipt by the Company of cash, certified bank check to its order,
or other consideration acceptable to the Company; provided that at the
discretion of the Board or the Committee, payment may be made in whole or in
part in shares of Stock of the Company, which Stock shall be valued at its then
fair market value as determined by the Board or Committee, the surrender or
cancellation of other rights to Stock of the Company, or the surrender or
cancellation of tandem rights granted with the award. Any consideration approved
by the Company that calls for the payment of the exercise price over a period of
more than one (1) year shall provide for interest, which shall be included as
part of the exercise price, that is equal to or exceeds the imputed interest
provided for in Internal Revenue Code Section 483 or any amendment or successor
section of like tenor.

         8. Withholding. If the grant or exercise of an award pursuant to this
Plan is subject to withholding or other trust fund payment requirements of the
Internal Revenue Code or applicable state or local laws, such requirements may,
to the extent permitted by the terms of the award and the then governing
provisions of the Internal Revenue Code, be met by the holder of the award
delivering shares of Stock or canceling options or other rights to acquire Stock
or by the Company withholding shares of Stock subject to the option, all with a
fair market value equal to such requirements.

         9. Incentive Options. In addition to the other restrictions and
provisions of this Plan and any award under this Plan, any option granted that
is intended to be an Incentive Option shall meet the following further
requirements:

                  (a) The exercise price of an Incentive Option shall not be
         less than the fair 



<PAGE>   4

         market value of the Stock on the date the Incentive Option is granted
         as determined by the Board or Committee and permitted by the applicable
         provisions of the Internal Revenue Code.

                  (b) No Incentive Option may be granted under the Plan to any
         employee that owns (either of record or beneficially) Stock possessing
         more than ten percent (10%) of the combined voting power of the Company
         or any parent or subsidiary corporation unless both the exercise price
         is at least one hundred and ten percent (110%) of the fair market value
         of the Stock on the date the Option is granted and the Incentive Option
         by its terms is not exercisable more than five (5) years after the date
         it is granted.

                  (c) Incentive Options may be granted only to employees of the
         Company or its subsidiaries, and only in connection with the employee's
         employment by the Company or the subsidiary. Notwithstanding the above,
         directors may be granted Incentive Options under the Plan, subject to,
         and to the extent permitted by, applicable tax statutes and
         regulations.

                  (d) The aggregate fair market value (determined as of the date
         the Incentive Option is granted) of the shares of Stock with respect to
         which Incentive Options are exercisable for the first time by any
         individual during any calendar year under the Plan (and all other Plans
         of the Company and its subsidiaries) may not exceed $100,000.00.

                  (e) No Incentive Option shall be transferable other than by
         will or the laws of descent distribution, and shall be exercisable
         during the lifetime of the optionee, only by the optionee to whom the
         Incentive Option is granted.

                  (f) No stock appreciation rights or other rights can be
         granted in tandem with an Incentive Option.

                  (g) Any employee acquiring shares of Stock pursuant to any
         Incentive Option granted under this Plan shall not sell, transfer or
         otherwise convey the Stock until after the date that is both two (2)
         years from the date the Incentive Option was granted and one (1) year
         from the date the Stock was acquired by the Employee pursuant to the
         exercise of the Incentive Option. If any employee makes a disqualifying
         disposition, he shall notify the Company within thirty (30) days of
         such transaction.

                  (h) No Incentive Option may be exercised unless the optionee
         was, within three (3) months of such exercise, and had been since the
         date the Incentive Option was granted, an eligible employee of the
         Company as specified in the applicable 



<PAGE>   5

         provisions of the Internal Revenue Code, unless the optionee dies
         during such three (3) month period; provided an Incentive Option may be
         exercised by any optionee who ceases employment due to a disability as
         defined in Internal Revenue Code 22(e)(3), or any amendment to that
         section or any successor section of like tenor, within twelve (12)
         months of such termination. An authorized absence or leave approved by
         the Board or Committee shall not be considered an interruption of
         employment for any purpose under the Plan.

                  (i) All Incentive Options shall be deemed to contain such
         other limitations and restrictions as are necessary to conform the
         Incentive Option to the requirements for "incentive stock options" as
         defined in Section 422 of the Internal Revenue Code, or any amendment
         or successor statute of like tenor.

                  (j) All of the foregoing restrictions and limitations are
         based on the governing provisions of the Internal Revenue Code as of
         the date of adoption of this Plan. If at any time the Internal Revenue
         Code is amended to permit the qualification of an Option as an
         incentive stock option without one or more of the foregoing
         restrictions or limitations or the terms of such restriction or
         limitation are modified, the Board or Committee may issue Incentive
         Options, and may modify existing Incentive Options in accordance with
         the amendments to the Internal Revenue Code, all to the extent that
         such action by the Board or Committee does not disqualify the Incentive
         Options from treatment as incentive stock options under the provisions
         of the Internal Revenue Code.

         10. Stock Appreciation Rights and Other Tandem Rights. The Board or
Committee, at the time of granting any award under the terms of this Plan, shall
have the authority to grant stock appreciation rights or other tandem rights
with respect to all or some of the shares of Stock covered by such award
pursuant to which the holder shall have the right to surrender all or part of
such award and thereby exercise the tandem rights; provided, however, that the
holder shall not have such right to surrender and obtain payment during the
first six (6) months of the term of the award, except in the event of death or
disability of the holder during such six (6) month period. Any payment under the
terms of the tandem rights may be made by the Company, at the discretion of the
Board or Committee as set forth in the written award, in Stock (at its fair
market value on the date of the notice of exercise, as determined by the Board
or Committee) or in cash, or partly in such Stock and partly in cash, as the
Board or Committee may determine. Any stock appreciation rights or other tandem
rights granted under the terms of this section may be exercised only when, and
only to the extent that, the holder is entitled to exercise all or a portion of
the underlying award. The terms of any Stock appreciation or other rights
granted shall, within the provisions of this Plan, be established by the Board
or Committee at the time of the grant, and any rights created thereby can only
be transferred in connection with the transfer of the underlying award. Stock
appreciation rights may only be exercised at a time when the fair 



<PAGE>   6

market value of the Stock subject to the award exceeds the exercise price of the
award.

         11. Dilution or Other Adjustment. In the event that shares of Stock of
the Company from time to time issued and outstanding are increased pursuant to a
stock split or a stock dividend, the number of shares of Stock then covered by
each outstanding Option granted hereunder shall be increased proportionately
with no increase in the total purchase price of the shares then so covered and
the number of shares of stock reserved for the purposes of the Plan shall be
increased by the same proportion. In the event that the shares of Stock of the
Company from time to time issued and outstanding are reduced by a combination or
consolidation of shares, the number of shares of Stock then covered by each
outstanding Option granted hereunder shall be reduced proportionately, with no
reduction in the total purchase price of the shares then so covered and the
number of shares of Stock reserved for the purposes of the Plan shall be reduced
by the same proportion. In the event that the Company should transfer assets to
another corporation and distribute the stock of such other corporation without
the surrender of Stock of the Company, and if such distribution is not taxable
as a dividend and no gain or loss is recognized by reason of Section 355 of the
Internal Revenue Code or a similar section, then the total purchase price of the
Stock then covered by each outstanding Option shall be reduced by an amount that
bears the same ratio to the total purchase price then in effect as the market
value of the stock distributed in respect of a share of the Stock of the
Company, immediately following the distribution, bears to the aggregate of the
market value at such time of a share of the Stock of the Company and the stock
distributed in respect thereof. In the event that the Company distributes the
stock of a subsidiary to its shareholders, makes a distribution of a major
portion of its assets, or otherwise distributes a significant portion of the
value of its issued and outstanding Stock to its shareholders, the number of
shares then subject to each outstanding award and the Plan may be adjusted, in
the discretion of the Board. All such adjustments shall be made by the Board,
whose determination upon the same shall be final and binding on all participants
under the Plan. No fractional share shall be issued, and any fractional shares
resulting from the computations pursuant to this section shall be eliminated
from the respective award. No adjustment shall be made for cash dividends or the
issuance to stockholders of rights to subscribe for additional Stock or other
securities.

         12. Awards to Foreign Nationals. The Board or Committee may, in order
to fulfill the purposes of this Plan and without amending the Plan, grant awards
to foreign nationals or individuals residing in foreign countries that contain
provisions, restrictions, and limitations different from those set forth in this
Plan and the awards made to United States residents, in order to recognize
differences amongst the countries in law, tax policy, and custom. Such awards
shall be made in an attempt to provide such individuals with essentially the
same benefits as contemplated by an award to United States residents under the
terms of this Plan.

         13. Assignment. No award granted under this Plan shall be transferable
other 


<PAGE>   7

than to a family member, a trust for the benefit of the holder or a family
member, a charity, or by will or the laws of descent and distribution. If any
award is transferred in accordance with the provisions of this section, it
cannot thereafter be transferred by the new holder, except to reconvey it to the
original holder. Except as permitted by the foregoing, each award granted under
the Plan and the rights and privileges thereby conferred shall not be
transferred, assigned, pledged, or hypothecated in any way (whether by operation
of law or otherwise, and shall not be subject to execution, attachment, or
similar process. On any attempt to transfer, assign, pledge, hypothecate, or
otherwise dispose of the award, or of any right or privilege conferred thereby,
contrary to the provisions hereof, or on the levy of any attachment or similar
process on such rights and privileges, the award and such rights and privileges
shall immediately become null and void.

         14. Stock Transfer Restrictions. All stock issued pursuant to the Plan
will be "restricted" securities as defined in Rule 144 of the Securities Act of
1933, as amended, registration statements under said Act or pursuant to an
exemption therefrom. All certificates evidencing shares covered by an Option and
any securities issued or placed or exchanged therefor, shall bear a restrictive
legend to such effect. The Company shall be under no obligation to register or
assist any Optionee in registering either the Options or the Stock issuable upon
exercise of the Option under the Federal Securities laws or any state securities
laws.

         15. Effect of Termination of Employment. In the event that any holder
is terminated or resigns from his position with the Company or a subsidiary
within six (6) months of the grant of an award, any unexercised portion of such
award shall immediately become null and void, and such holder shall have no
further rights thereunder. In the event that any officer, director, or employee
of the Company or a subsidiary is terminated at any time for, in the
determination of the Board, materially breaching the terms of his employment,
gross negligence in the performance of his duties, substantial failure to meet
written standards established by the Company for the performance of his duties,
criminal misconduct, or willful or gross misconduct in the performance of his
duties, the Board may cancel any and all rights such individual may have in the
unexercised portion of any award held at the time of termination. Except as
provided above, the Stock Option may be exercised within three (3) months of
termination; provided, however, that the Stock Option may be exercised by the
Optionee for twelve (12) months following termination or cessation of employment
if termination is due to a disability as defined in Internal Revenue Code
22(e)(3) or any amendment to that section or any successor section of like
tenor. The Board or Committee may establish any other restriction on the
exercise of award subsequent to the termination or resignation of any individual
that it deems appropriate at the time of the grant of the award.

         16. Death of Optionee. The Stock Options granted under the Plan shall
be exercisable during the Employee's lifetime and until the expiration of twelve
(12) months 



<PAGE>   8

after the Employee's death, subject to the ten-year limitation described herein.

         17. Listing and Registration of Shares. Each award shall be subject to
the requirement that if at any time the Board shall determine, in its sole
discretion, that it is necessary or desirable to list, register, or qualify the
shares covered thereby on any securities exchange or under any state or federal
law or obtain the consent or approval of any governmental agency or regulatory
body as a condition of, or in connection with, the granting of such award or the
issuance or purchase of shares thereunder, such award may not be exercised in
whole or in part unless and until such listing, registration, consent, or
approval shall have been effected or obtained free of any conditions not
acceptable to the Board.

         18. Expiration and Termination of the Plan. The Plan may be abandoned
or terminated at any time by the Board except with respect to any awards then
outstanding under the Plan. No Incentive Option shall be granted pursuant to the
Plan after the earlier of (i) ten (10) years after the date the Plan is adopted
by the Board; or (ii) ten (10) years after the date the Plan is approved by the
shareholders of the Company.

         19. Form of Awards. Awards granted under the Plan shall be represented
by a written agreement which shall be executed by the Company and the holder,
and which shall contain such terms and conditions as may be determined by the
Board or Committee and permitted under the terms of this Plan. Option agreements
evidencing Incentive Options shall contain such terms and conditions, among
others, as may be necessary, in the opinion of the Board or Committee, to
qualify them as Incentive Stock Options under Internal Revenue Code 422 or any
amendment or successor statute of like tenor.

         20. Amendment of the Plan. The Board may at any time, and from time to
time, modify and amend the Plan in any respect; provided, however, that no such
amendment shall, without the approval of the shareholders, cause the Plan to no
longer comply with the applicable provisions of the Internal Revenue Code with
respect to Incentive Options.

         21. Continuing Compliance with Applicable Law. Notwithstanding any
provision to the contrary contained herein, the Plan shall be deemed to be
automatically amended as is necessary with respect to the issuance of Incentive
Options to maintain the Plan in compliance with the provisions of Section 422 of
the Internal Revenue Code, and regulations promulgated hereunder from time to
time, or any amendment or successor statute thereto.

                            STOCK PURCHASE AGREEMENT


        THIS STOCK PURCHASE AGREEMENT (this "Agreement") is made and entered
into this 1 day of December, 1996, by and among Zevex International, Inc., a
Nevada corporation (hereinafter referred to as the "Company") and Blosch and
Holmes, a partnership composed of Kirk Blosch and Jeff Holmes, (hereinafter
referred to as "BH"), on the following:

                                    PREMISES

        A.  The Company is interested in raising capital through the sale of
up to 500,000 shares of its common stock, par value $0.001 per share (the
"Common Stock") and 500,000 common stock purchase warrants (the "Warrants") a
copy of which is attached hereto as exhibit "A," to purchase shares of Common
Stock at an exercise price of $3.50 per share. The shares of Common Stock and
the Warrants will be sold for an aggregate price of $2.50 per share of Common
Stock and Warrant.

        B.  BH has engaged in preliminary discussions with the Company regarding
the purchase of the shares of Common Stock and the Warrants which would be
offered and sold in a transaction or transactions complying with exemptions from
the registration requirements of the Securities Act of 1933, as amended (the
"Securities Act"), as well as under the securities laws of certain states.

        C.  The Company and BH want to set forth their understanding as to the
terms and conditions of the purchase by BH of the shares of Common Stock and
Warrants.

                                   AGREEMENT

        BASED, upon the foregoing premises, which are incorporated herein by
this reference, and for and in consideration of the mutual promises and 
covenants hereinafter set forth, and other good and valuable consideration the 
receipt and adequacy of which are hereby acknowledged, it is agreed as follows:

                                   ARTICLE 1
                     PURCHASE OF COMMON STOCK AND WARRANTS

        1.01  Purchase and Sale of Common Stock and Warrants.  BH agrees to
purchase from the Company and the Company agrees to sell to BH 500,000 shares of
Common Stock and 500,000 Warrants for a purchase price of $2.50 per share of
Common Stock and Warrant. BH, at its option, may purchase the shares of Common
Stock and Warrants in an entity or entities that it shall create which may
contain partners, members or shareholders; provided that, all such individuals
or entities who are members, shareholders or partners of such entity shall
themselves meet certain suitability and accredited investor standards which, if
such entity did not exist, would allow them to purchase shares of Common Stock
and Warrants directly from the Company without adversely affecting the
exemption(s) from the registration requirements of the Securities Act relied
upon in this transaction.

        1.02.  Closing Date.  The offer and sale of the shares of Common Stock
and Warrants shall be consummated within sixty (60) days of the date the
Company delivers the private placement memorandum to BH as set forth herein.

1.03    Closing Events.

        (a)     The Company Deliveries. Subject to fulfillment or waiver of the
conditions set forth in herein, the Company shall deliver to BH or such other
entities as BH shall designate at closing all the following:

                (i)     A certificate of good standing from the secretary of
        State of Nevada, issued as of a date within five days prior to the
        Closing Date, certifying that the Company is in good standing as a
        corporation in the State of Nevada;

                (ii)    Copies of the resolutions of the Company's board of
        directors authorizing the execution and performance of this Agreement

                                 OF THE COMPANY

        As an inducement to, and to obtain the reliance of BH in connection
with its purchase of the shares of Common Stock and Warrants, the Company
represents and warrants as follows:

        2.01  Private Offering.  The offer, offer for sale, and sale of the
shares of Common Stock and Warrants have not been and will not be registered

Common Stock and Warrants shall be offered for sale and sold pursuant to the
exemptions from the registration requirements of Section 5 of the Securities
Act provided by Sections 3(b) and/or 4(2) thereof. The Company shall, insofar
as its own actions are concerned, conduct the offer and sale in compliance with

authority, and legal right and has taken, or will take, all action required by
law, its articles of incorporation, bylaws, and otherwise to execute and
deliver this Agreement and to consummate the transactions herein contemplated
including the issuance of the shares of Common Stock and Warrants. The board of
directors of the Company has authorized and approved the execution, delivery,
and performance of this Agreement and the transactions contemplated hereby
including the issuance of the shares of Common Stock and the Warrants.

        2.03  Legal Right.  To the best knowledge of the Company, the
performance of this Agreement and the consummation of the transactions herein
contemplated will not result in a material breach or violation of any of the
terms and provisions of, or constitute a default under, any statute (except
federal and state securities laws, compliance with which is elsewhere provided
for in particular detail), indenture, mortgage or other agreement or instrument
to which the Company is a party or by which it is bound by any






                                      -3-
<PAGE>   4
order, rule or regulation directed to the Company or its affiliates by any
court or governmental agency or body having jurisdiction over them; and no
other consent, approval, authorization or action is required for the
consummation of the transactions herein contemplated other than such as have
been obtained.

        2.04    Validly Issued. The Common Stock, when issued, will be duly
authorized, validly and legally issued, and non-assessable.

        2.05    Warrants' Designations. The Warrants when issued will contain
(i) the right to receive one share of Common Stock at an exercise price of
$3.50 for a period of five years from the date of issuance; (ii) standard
"piggy back" registration rights which provide the holder of the Warrant the
right to have shares of Common Stock issuable on exercise of the Warrants
included in any registration statement the Company should file with the
Securities and Exchange Commission during any time the Warrants are
exercisable; and (iii) the right to transfer the Warrants, subject to
compliance with applicable federal and state securities laws.

        2.06    Organization. The Company has been duly organized and is now,
and always during the period of the offer and sale will be, a validly existing
corporation under the laws of the state of Nevada, lawfully qualified to
conduct the business for which it was organized and which it proposes to
conduct. The Company will always during the period of the offer and sale of the
shares of Common Stock and Warrants be qualified to conduct business as a
foreign corporation in each jurisdiction where the nature of its business
requires such qualification.

        2.07    Capitalization. The Company has an authorized capitalization of
5,000,000 shares of Common Stock, $0.001 par value. The Company currently has
1,495,716 shares of Common Stock issued and outstanding and no shares of Common
Stock reserved for issuance pursuant to outstanding warrants. There are 94,800
outstanding options, and no outstanding warrants or other rights to purchase
securities, the Company, to the best of its knowledge, has not made any
intentional or reckless violations of the anti-fraud provisions of the federal
securities laws, rules or regulations promulgated there under or the laws,
rules or regulations of any jurisdiction wherein such securities transactions
or solicitations occurred.

        2.08    Integration. The Company:

                (a) To the best of its knowledge has not offered, offered to
        sell, offered for sale or sold any other securities (as hereinafter
        defined) the offer, offer to sell, offer for sale or sale of which would
        be "integrated" under the standards of existing published rules and
        regulations under the Securities Act with the offers, offers to sell,
        offers for sale or sales of the Common Stock and Warrant proposed to be
        made by the Company pursuant hereto in determining whether a public
        offering of the shares of Common Stock and Warrants has been made so as
        to render the exemptions provided by Section 3(b) or 4(2) of the
        Securities Act unavailable with respect to the proposed offer and sale
        of the shares of Common Stock and Warrants hereunder; and

                (b) To the best of its ability shall not offer, offer to sell,
        offer for sale or sell any shares of Common Stock, Warrants or other
        securities except and to the extent any such offer, offer to sell, offer
        for sale or sale, shall not render unavailable the exemptions from
        registration and


                                      -4-
<PAGE>   5
        qualification requirements of applicable federal and state securities
        laws relied upon with respect to the offer and sale of the shares of
        Common Stock and Warrants contemplated by this Agreement.

                The term "Other Securities" as used elsewhere herein refers to
        the offers, offers for sale, offers to sell and sales of any Common
        Stock or any other securities of the Company other than any offers,
        offers to sell, offers for sale, or sales of the shares of Common Stock
        and Warrants to be made by or through the Company hereunder.

        2.09    Administrative Action.  The Company will notify you immediately
and confirm the notice in writing of the issuance by the Commission or by any
state securities administration of any stop order suspending the effectiveness
of any qualification of the shares of Common Stock and Warrants for sale or
enjoining the offer or sale of the shares of Common Stock and Warrants or of
the initiation of any proceedings for that purpose. The Company will make every
reasonable effort to prevent the issuance of any such stop order and, if any
such stop order shall at any time be issued, to obtain the lifting thereof at
the earliest possible moment.

        2.10    Financial Statements.

                (a)     The Company's financial statements for the dates and

        liabilities or obligations (absolute or contingent) which should be
        reflected in a balance sheet or the notes thereto prepared in accordance
        with generally accepted accounting principles, and all assets reflected
        therein present fairly the assets of the Company, in accordance with
        generally accepted accounting principles. The Company maintains and will
        continue to maintain a standard system of accounting established and
        maintained in a manner permitting the preparation of financial
        statements in accordance with generally accepted accounting principles.
        The financial statements have been presented in accordance with the
        requirements of regulation S-B, item 310 promulgated by the Securities
        and Exchange Commission (the "Commission") regarding the form, content
        and requirements for financial presentation to be filed with the
        Commission.

                (b)     To the best knowledge of the Company, the books and
        records, financial and otherwise, of the Company are in all material
        respects complete and correct and have been maintained in accordance
        with sound business and bookkeeping practices so as to accurately and
        fairly reflect, in reasonable detail, the transactions and dispositions
        of the assets of the Company. The Company has maintained a system of
        internal accounting controls sufficient to provide reasonable assurances
        that (i) transactions have been and are executed in accordance with
        management's general or specific authorization; (ii) transactions are
        recorded as necessary to permit the preparation of financial statements
        in conformity with generally accepted accounting principles or any other
        criteria applicable to such statements and to maintain accountability
        for assets; (iii) access to assets is permitted only in accordance with
        management's general or specific authorization; and (iv) the recorded
        accountability for assets is compared with the existing assets at
        reasonable intervals, and appropriate action is taken with respect to
        any differences.

Date all tax returns required to be filed by it from inception to the Closing
Date. All such returns and reports are accurate and correct in all material
respects, except for returns or reports that are not material or that would not
create an adverse effect. The Company has no liabilities with respect to the
payment of any federal, state, county, local, or other taxes (including any
deficiencies, interest, or penalties) accrued for or applicable to the period

the assets of, or as successor to, any other corporation or entity, except for
taxes accrued but not yet due and payable, and no deficiency assessment or
proposed adjustment of any such tax return is pending, proposed or
contemplated. Proper and accurate amounts of taxes have been withheld by or on

Company for all periods ending on or before the date hereof, and all deposits

        The obligations of the Company under this Agreement are subject to the
satisfaction, at or before the closing date, of the following conditions:

        4.01    Representations.  BH, or any entity which it creates to
purchase the shares of Common Stock and Warrants, shall provide the Company
such representations and warrants necessary to satisfy the Company and its
counsel that BH and any partners, member or shareholder in any entity
purchasing the shares of Common Stock and Warrants meets certain suitability
requirements and that such sale will comply with exemptions from the
registration processes of the Securities Act and of certain state statutes.

                               SPECIAL COVENANTS

        5.01    Activities of the Company.

                (a)     From and after the date of this Agreement until the
        closing date and except as set forth herein or as permitted or
        contemplated by this Agreement, the Company will:

                        (i)     Carry on its business in substantially the same
                manner as it has heretofore;

                        (ii)    Maintain in full force and effect insurance
                comparable in amount and in scope of coverage to that now
                maintained by it;

                        (iii)   Perform in all material respects all of its
                obligations under material contracts, leases, and instruments
                relating to or affecting its assets, properties, and business;

                        (iv)    Use its best efforts to maintain and preserve
                its business organization intact, to retain its key employees,
                and to maintain its relationships with its material suppliers
                and customers;




                                      -10-
<PAGE>   11
                (v)    Except to the extent that non compliance is not material
        or adverse to the Company, duly and timely file for all taxable periods
        ending on or prior to the Closing Date all federal, state, county, and
        local tax returns required to be filed by or on behalf of such entity or
        for which such entity may be held responsible and shall pay, or cause to
        pay, all taxes required to be shown as due and payable on such returns,
        as well as all installments of tax due and payable during the period
        commencing on the date of this Agreement and ending on the closing date;
        and

                (vi)   Fully comply with and perform in all material respects
        all obligations and duties imposed on it by all federal and state laws
        and all rules, regulations, and orders imposed by federal or state
        governmental authorities.

        (b)  From and after the date of this Agreement and except as provided
herein until the closing date, the Company will not:

                (i)    Make any change in its articles of incorporation or
        bylaws;

                (ii)   Enter into or amend any material contract, agreement, or
        other instrument, except in the ordinary course of business; and

                (iii)  Enter into any agreement for the sale of the Company's
        securities without the prior approval of the other party.

        5.02  Access to Books and Records.  Until the closing date, the Company
will afford to BH and its authorized representatives full access to the
properties, books, and records of the Company in order that BH may have full
opportunity to make such reasonable investigation as it shall desire to make of
the affairs of the Company and will furnish the BH with such additional
financial and other information as to the business and properties of the
Company as BH shall from time to time reasonably request.

        5.03  Piggy Back Registration Rights.  If at any time during the next
five years the Company shall prepare and file a registration statement with the
Commission to register shares of its Common Stock, excluding an S-8 or S-4
registration statement, the Company agrees to register the 500,000 shares of
Common Stock to be issued hereunder as well as the shares of Common Stock
issueable on the exercise of the Warrants in such registration statement as
follows:

                (a)  The Company shall promptly give written notice that it
        intends to file a registration statement to the holders of the shares of
        Common Stock and Warrants at least 45 days prior to any such filing. The
        holders of the shares of Common Stock and Warrants will have 20 days
        after receipt of the notice from the Company to notify, in writing, the
        Company of their desire to include in such registration statement shares
        of Common Stock. The Company shall include in such registration
        statement that number of shares of Common Stock requested by the holders
        subject to the provisions herein.

                (b)  The Company will pay all expenses of such registration
        statement, including, without limitation, printing charges, legal fees,
        and disbursements of counsel for the Company,






                                      -11-
<PAGE>   12
blue sky expenses, accounting fees, and filing fees, but not including legal
fees and disbursements of counsel to the Holders.

        (c)     If the Company, in its sole discretion, determines to file a
registration statement or registration statements during the next five years,
except for registration statements for the sole purpose of registering shares
for employees, directors or consultants of the Company, it shall take all steps
reasonably necessary to permit the registration of the shares of Common Stock
and the exercise of the Warrants and the issuance of the shares of Common Stock
pursuant to such exercise under the applicable state securities laws of those
states in which the shares of Common Stock and Warrants were issued or
originally registered or qualified for sale and issuance by the Company. The
Company will take such reasonable steps which it determines, in its sole
discretion, are necessary to permit the registration or qualification of the
shares of Common Stock and the exercise of Warrants and the issuance of the
shares of Common Stock pursuant to such exercise under the laws of any other
state in which a holder of the shares of Common Stock or Warrants then resides
on the written request to do so by such holder, but in no event shall the
Company be required to take such steps in any state other than those states in
which the shares of Common Stock and Warrants were originally qualified or
registered, and the Company shall not be obligated to execute or file any
general consent to service of process or to qualify as a foreign corporation to
do business under the laws of any such jurisdiction. Holders of shares of
Common Stock and Warrants who reside in any state where the Company cannot,
with the exercise of reasonable diligence, obtain qualification for the
exercise of the Warrants, and the issuance of the shares of Common Stock may
not, as a result thereof be able to exercise their Warrants, and the Company is
under no obligation to make such exercise possible in such circumstances. In
the event that the Company determines to proceed with the qualification of the
exercise of the Warrants and the issuance of the shares of Common Stock under
the securities laws of a particular state, then the exercise of such Warrants
shall not be effective and the shares of Common Stock shall not be issued until
such qualification becomes effective. When qualification under applicable state
securities laws is required, the Company shall take such action within ten days
following the date on which the Company first files the registration statement.
The costs of obtaining such state qualification shall be borne by the Company.

        (d)     The Company shall promptly notify the holders of the shares of
Common Stock and the Warrants of the effective date of any registration
statement filed by the Company and the date on which the shares of Common Stock
become qualified or registered under the state securities laws of any state in
which the Company obtains qualification or registration with respect to such
shares.

        (e)     Notwithstanding any provisions to the contrary contained
herein, the Company shall not be required to include any of the shares of
Common Stock in any registration statement or post-effective amendment with
respect to shares offered in any underwriting:

                (i)     Unless the holders of the shares of Common Stock and
        Warrants agree to offer such shares of Common Stock, on the same terms
        and conditions as the Company's shares of Common Stock are being
        offered, and to sign an underwriting agreement in the form to be signed
        by the other offerors; or




                                      -12-
<PAGE>   13
                        (ii)    If, in the good faith and reasonable opinion of
                the managing underwriter of the offering, the sale of the shares
                of Common Stock to be included would be materially detrimental
                to the remainder of the offerors.

                (f)     The shareholders desiring to sell shares of Common Stock
        pursuant to the registration rights granted herein shall provide the
        Company with all information relating to such sale and on which the
        Company shall be entitled to rely and to include such information in any
        such registration statement. The holders of the shares of Common Stock
        and Warrants shall indemnify and save harmless the Company (and all
        other persons who may be subject to liability under the Act or
        otherwise) from and against any and all claims, actions, suits,
        liabilities, losses, damages, and expenses of every nature and character
        (including, but not by way of limitation, all reasonable attorneys' fees
        and all amounts paid in settlement of any claim, action, or suit) which
        arise or result directly or indirectly from any untrue statement of a
        material fact furnished by such holder in connection with such
        registration or qualification, or from the failure of the holder of the
        shares of Common Stock to furnish material information in connection
        with the facts required to be included in such registration statement,
        notification, or post-effective amendment necessary to make the
        statements therein not misleading, or from any sales or offers of the
        shares of Common Stock so registered after ninety (90) days from the
        effective date of such registration statement or notification.

                (g)     All sales pursuant to any such registration statement
        shall be made in accordance with the provisions of the Securities Act
        and the Securities Exchange Act of 1934, as amended, and the Company
        shall not be required to include any such shares of Common Stock in any
        registration until it has received written assurances satisfactory in
        form and substance to the Company from the shareholders offering such
        shares of Common Stock that such sales shall be so conducted. On notice
        to any shareholder offering shares of Common Stock covered by a
        registration statement that such registration statement or prospectus
        relating thereto requires revision, such holder will immediately cease
        to make offers or sales pursuant to such registration statement, return
        all such registration statements and prospectuses to the Company, and
        not resume offers until he or she has been provided with an updated
        prospectus by the Company. The Company is under no obligation to
        maintain the effectiveness of any registration statement for more than
        an aggregate of 90 days.

        5.04    Securities Representations. BH understands and agrees that the
consummation of this Agreement including the issuance of shares of Common Stock
and Warrants as contemplated hereby, constitutes the offer and sale of
securities under the Securities Act and applicable state statutes. BH agrees
that such transactions shall be consummated in reliance on exemptions from the
registration and prospectus delivery requirements of such statutes which depend,
among other items, on the circumstances under which such securities are
acquired. In order to provide documentation for reliance upon exemptions from
the registration and prospectus delivery requirements for such transactions, BH,
or the entities it creates to purchase the securities, agrees that it will sign
appropriate representations and warrants related to its suitability to invest in
the Company, including an investment letter and suitability questionnaire.

        5.05.   Additional Filings. In connection with the transaction
contemplated by this Agreement, the Company and BH shall each file, with the
assistance of the other and their respective legal counsel, such notices,
applications, reports, or other instruments as may be deemed by them to be
necessary or


                                      -13-
<PAGE>   14
appropriate in an effort to document reliance on such exemptions, and the
appropriate regulatory authority in the states where the shares of Common Stock
and Warrants will be deemed to have been offered and sold, all to the extent
and in the manner as may be deemed by such parties to be appropriate.

        5.06    Legal Opinions. BH acknowledges that the basis for relying on
exemptions from registration or qualifications are factual, depending on the
conduct of the various parties, and that no legal opinion or other assurance
will be required or given to the effect that the transactions contemplated
hereby are in fact exempt from registration or qualification.

        5.07    Compliance with Rule 144.

                (a)     The Company will use its best efforts to at all times
        satisfy the current public information requirements of rule 144 
        promulgated under the Securities Act so that its shareholders can sell
        restricted securities that have been held for two years or more or such
        other restricted period as required by rule 144 as it is from time to
        time amended. This covenant shall survive the closing of this Agreement.

                (b)     Upon being informed in writing by any person holding
        restricted stock sold pursuant to this Agreement that such person
        intends to sell any shares under rule 144 promulgated under the
        Securities Act (including any rule adopted in substitution or 
        replacement thereof), the Company will certify in writing to such person
        that it is compliance with rule 144 current public information
        requirement to enable such person to sell such person's restricted stock
        under rule 144, as may be applicable under the circumstances.

                (c)     If any certificate representing any such restricted
        stock is presented to the Company's transfer agent for registration or
        transfer in connection with any sales theretofore made under rule 144,
        provided such certificate is duly endorsed for transfer by the
        appropriate person(s) or accompanied by a separate stock power duly
        executed by the appropriate person(s) in each case with reasonable
        assurances that such endorsements are genuine and effective, and is
        accompanied by an opinion of counsel satisfactory to the Company and its
        counsel that such transfer has complied with the requirements of rule
        144, as the case may be, the Company will promptly instruct its transfer
        agent to register such transfer and to issue one or more new
        certificates representing such shares to the transferee and, if
        appropriate under the provisions of rule 144, as the case may be, free
        of any stop transfer order or restrictive legend.

        5.08    New Directorships. Upon closing of the transactions
contemplated by this Agreement, a nominee of BH shall be appointed to the board
of directors of the Company to fill a currently vacant directorship, and at the
request of BH, the current board of directors of the Company may be expanded to
seven directorships with the new directorship being filled with an individual
mutually acceptable to the Company and BH. The Company's current management
shall support the nominee(s) of BH at any and all shareholder meeting where
directors are to be nominated and elected.


                                      -14-
<PAGE>   15
        5.09    Future Obligations. The Company shall upon the closing of this
Agreement: 

                (a)     Retain as auditors to the Company a "big six" 
        accounting firm for purposes of auditing the Company's future financial
        statements commencing with the December 31, 1997, financial statements;

                (b)     Create an advisory board of professional advisors who 
        shall be selected in conjunction with BH;

                (c)     Retain a public relations firm with national marketing
        experience and provide a maximum annual budget of $30,000 for public
        relations expense; and

                (d)     Require all directors to be shareholders holding at 
        least 5,000 shares of Common Stock unless waived by BH.

        This covenant shall survive the closing of this Agreement.

        5.10.   Expenses of Sale. The Company will pay all expenses incident to
the performance of its obligations hereunder, including but not limited to the
fees and expenses of its counsel and accountants, the cost of preparation of a
private placement memorandum and the cost of qualifying the offer and sale of
the shares of Common Stock and Warrants in various states or obtaining an
exemption from state registration requirements.

        5.11    Company's Indemnification. The Company will indemnify and hold
harmless BH and Kirk Blosch and Jeff Holmes, individually, from and against any
and all losses, claims, damages, expenses, liabilities, or actions to which any
of them may become subject under applicable law (including the Securities Act
and the Securities Exchange Act) and will reimburse them for any legal or other
expenses reasonably incurred by them in connection with investigating or
defending any claims or actions, whether or not resulting in liability, insofar
as such losses, claims, damages, expenses, liabilities, or actions arise out of
or are based upon any untrue statement or alleged untrue statement of material
fact contained in any application or statement filed with a governmental body
or arising out of or are based upon the omission or alleged omission to state
therein a material fact required to be stated therein, or necessary in order to
make the statements therein not misleading, but only insofar as any such
statement or omission was made in reliance upon and in conformity with
information furnished in writing by the Company expressly for use therein. The
indemnity agreement contained herein shall remain operative and in full force
and effect, regardless of any investigation made by or on behalf of BH, Kirk
Blosch and Jeff Holmes and shall survive the consummation of the transactions
contemplated by this Agreement.

        5.12    BH's Indemnification. BH will indemnify and hold harmless the
Company and its directors and officers, and each person, if any, who controls
the Company within the meaning of the Securities Act, from and against any and
all losses, claims, damages, expenses, liabilities, or actions to which any of
them may become subject under applicable law (including the Securities Act and
the Securities Exchange Act) and will reimburse them for any legal or other
expenses reasonably incurred by them in connection with investigating or
defending any claims or actions, whether or not resulting in liability, insofar
as such losses, claims, damages, expenses, liabilities, or actions arise out of
or are based upon any untrue statement or alleged untrue statement of material
fact contained in any application or 


                                      -15-
<PAGE>   16
statement filed with a governmental body or arising out of or are based upon
the omission or alleged omission to state therein a material fact required to be
stated therein, or necessary in order to make the statements therein not
misleading, but only insofar as any such statement or omission was made in
reliance upon and in conformity with information furnished in writing by BH
expressly for use therein. The indemnity agreement contained herein shall
remain operative and in full force and effect, regardless of any investigation
made by or on behalf of the Company and shall survive the consummation of the
transactions contemplated by this Agreement.

        5.13  Future Compensation.  The Company will not use the funds obtained
hereunder for (i) paying any accrual or arrangement for or payment of bonuses
or special compensation of any kind or any severance or termination pay to any
present or former officer or employee; (ii) paying any increase in the rate of
compensation payable or to become payable by it to any of its officers or
directors or any of its employees whose monthly compensation exceeds $4,000; or
(iii) paying any increase in any profit-sharing, bonus, deferred compensation,
insurance, pension, retirement, or other employee benefit plan, payment, or
arrangement made to, for, or with their officers or directors;

        5.14  Lock Up of Shares.  The Company agrees to obtain a two year lock
up on the 130,000 shares of Common Stock held by Doug Anderson and received by
Mr. Anderson in relation to his sale of property to the Company. The lock up
agreement shall prevent Mr. Anderson from selling any of the 130,000 shares of
Common Stock for a period of two years and after the two year period Mr.
Anderson shall be permitted to sell only 25,000 shares of Common Stock during
any 90 day period. The terms and conditions of the agreement to prevent the sale
of Mr. Anderson shares of Common Stock shall be subject to the approval of BH.
Mr. Anderson, subject to the terms and conditions of the above "lock up," shall
be given the same "piggy back" registration rights of BH set forth in section
5.03 hereof; provided that, during all periods where Mr. Anderson would be
subject to the above "lock up," the Company will not be obligated to include Mr.
Anderson as a selling shareholder in any registration statement the company
files in that Mr. Anderson would not be able to sell the shares of Common Stock
registered in such registration statement due to the "lock up." This covenant
shall survive the closing of this Agreement.

                     AMENDMENT TO STOCK PURCHASE AGREEMENT

         This Amendment to Stock Purchase Agreement (this "Amendment") is
entered into as of September 30, 1997 by and among Zevex International, Inc., a
Nevada corporation (the "Company") and Blosch & Holmes, L.L.C., a Utah limited
liability company (hereinafter referred to as "BH"), collectively referred to
hereinafter as the "Parties" or individually, a "Party."

         WHEREAS the Parties hereto have previously entered into a certain
Stock Purchase Agreement, dated December 1, 1996 (the "Agreement"), wherein BH
agreed to purchase 500,000 shares of Common Stock of the Company ("Common
Stock") and warrants for an additional 500,000 shares of Common Stock;

         WHEREAS BH has transferred the warrants and certain rights pursuant
thereto;

         WHEREAS the parties desire to amend the Agreement in certain respects;

         NOW, THEREFORE, in consideration of the mutual promises contained in
the Agreement and in this Amendment, the Parties hereto agree as follows:

         1.      Article V of the Agreement shall be amended in its entirety to
read as follows:

                                   ARTICLE V
                               SPECIAL COVENANTS

                 5.01     Piggy Back Registration Rights.  If at any time
         during the next five years the Company shall file a registration
         statement with the Commission to register shares of its Common Stock,
         excluding an S-8 or S-4 registration statement, the Company agrees to
         register the 500,000 shares of Common Stock to be issued hereunder as
         well as the shares of Common Stock issuable on the exercise of the
         Warrants in such registration statement as follows:

                 (a)      The Company shall promptly give written notice that
         it intends to file a registration statement to the holders of the
         shares of Common Stock and Warrants at least 45 days prior to any such
         filing.  The holders of the shares and Warrants will have 20 days
         after receipt of the notice from the Company to notify, in writing,
         the Company of their desire to include in such registration statement
         shares of Common Stock.  The Company shall include in such
         registration statement that number of shares of Common Stock requested
         by the holders subject to the provisions herein.

                 (b)      The Company will pay all expenses of such
         registration statement, including, without limitation, printing
         charges, legal fees, and disbursements of counsel for the Company,
         blue sky expenses, accounting fees, and filing fees, but not including
         legal fees and disbursements of counsel to the Holders.
<PAGE>   23
                 (c)      If the Company, in its sole discretion, determines to
         file a registration statement or registration statements during the
         next five years, except for registration statements for the sole
         purpose of registering shares for employees, directors or consultants
         of the Company, it shall take all steps reasonably necessary to permit
         the registration of the shares of Common Stock and the exercise of the
         Warrants and the issuance of the shares of Common Stock pursuant to
         such exercise under the applicable state securities laws of those
         states in which the shares of Common Stock and Warrants were issued or
         originally registered or qualified for sale and issuance by the
         Company.  The Company will take such reasonable steps which it
         determines, in its sole discretion, are necessary to permit the
         registration or qualification of the shares of Common Stock and the
         exercise of Warrants and the issuance of the shares of Common Stock
         pursuant to such exercise under the laws of any other state in which a
         holder of the shares of Common Stock or Warrants then resides on the
         written request to do so by such holder, but in no event shall the
         Company be required to take such steps in any state other than those
         states in which the shares of Common Stock and Warrants were
         originally qualified or registered, and the Company shall not be
         obligated to execute or file any general consent to service of process
         or to qualify as a foreign corporation to do business under the laws
         of any such jurisdiction.  Holders of shares of Common Stock and
         Warrants who reside in any state where the Company cannot, with the
         exercise of reasonable diligence, obtain qualification for the
         exercise of the Warrants, and the issuance of the shares of Common
         Stock may not, as a result thereof be able to exercise their Warrants,
         and the Company is under no obligation to make such exercise possible
         in such circumstances.  In the event that the Company determines to
         proceed with the qualification of the exercise of the Warrants and the
         issuance of the shares of Common Stock under the securities laws of a
         particular state, then the exercise of such Warrants shall not be
         effective and the shares of Common Stock shall not be issued until
         such qualification becomes effective.  When qualification under
         applicable state securities laws is required, the Company shall take
         such action within ten days following the date on which the Company
         first files the registration statement.  The costs of obtaining such
         state qualification shall be borne by the Company.

                 (d)      The Company shall promptly notify the holders of the
         shares of Common Stock and the Warrants of the effective date of any
         registration statement filed by the Company and the date on which the
         shares of Common Stock become qualified or registered under the state
         securities laws of any state in which the Company obtains
         qualification or registration with respect to such shares.

                 (e)      Notwithstanding any provisions to the contrary
         contained herein, the Company shall not be required to include any of
         the shares of Common Stock in any registration statement or
         post-effective amendment with respect to shares offered in any
         underwriting:


                                       2
<PAGE>   24
                                  (i)      Unless the holders of the shares of
                          Common Stock and Warrants agree to offer such shares
                          of Common Stock, on the same terms and conditions as
                          the Company's shares of Common Stock are being
                          offered, and to sign an underwriting agreement in the
                          form to be signed by the other offerors; or

                                  (ii)     If, in the good faith and reasonable
                          opinion of the managing underwriter of the offering,
                          the sale of the shares of Common Stock to be included
                          would be materially detrimental to the remainder of
                          the offerors.

                 (f)      The shareholders desiring to sell shares of Common
         Stock pursuant to the registration rights granted herein shall provide
         the Company with all information relating to such sale and on which
         the Company shall be entitled to rely and to include such information
         in any such registration statement.  The holders of the shares of
         Common Stock and Warrants shall indemnify and save harmless the
         Company (and all other persons who may be subject to liability under
         the Act or otherwise) from and against any and all claims, actions,
         suits, liabilities, losses, damages, and expenses of every nature and
         character (including, but not by way of limitation, all reasonable
         attorneys' fees and all amounts paid in settlement of any claim,
         action, or suit) which arise or result directly or indirectly from any
         untrue statement of a material fact furnished by such holder in
         connection with such registration or qualification, or from the
         failure of the holder of the shares of Common stock to furnish
         material information in connection with the facts required to be
         included in such registration statement, notification, or
         post-effective amendment necessary to make the statements therein not
         misleading, or from any sales or offers of the shares of Common Stock
         so registered after ninety (90) days from the effective date of such
         registration statement or notification.

                 (g)      All sales pursuant to any such registration statement
         shall be made in accordance with the provisions of the Securities Act
         and the Securities Exchange Act of 1934, as amended, and the Company
         shall not be required to include any such shares of Common Stock in
         any registration until it has received written assurances satisfactory
         in form and substance to the Company from the shareholders offering
         such shares of Common Stock that such sales shall be so conducted.  On
         notice to any shareholder offering shares of Common Stock covered by a
         registration statement that such registration statement or
         prospectuses relating thereto requires revision, such holder will
         immediately cease to make offers or sales pursuant to such
         registration statement, return all such registration statements and
         prospectus to the Company, and not resume offers until he or she has
         been provided with an updated prospectus by the Company.  The Company
         is under no obligation to maintain the effectiveness of any
         registration statement for more than an aggregate of 90 days.

                 5.02     Compliance with Rule 144.

                 (a)      The Company will use its best efforts to at all times
         satisfy the current public information requirements of rule 144
         promulgated under the Securities Act so that its shareholders can sell
         restricted securities that have been held for two years or more or
         such other restricted period as required by rule 144 as it is from
         time to time amended.  This covenant shall survive the closing of this
         Agreement.

                 (b)      Upon being informed in writing by any person holding
         restricted stock sold pursuant to this Agreement that such person
         intends to sell any shares under rule 144 promulgated under the
         Securities Act (including any rule adopted in substitution or
         replacement thereof), the Company will certify in writing to such
         person that it is in compliance with rule 144 current public
         information requirement to enable such person to sell such person's
         restricted stock under rule 144, as may be applicable under the
         circumstances.

                 (c)      If any certificate representing any such restricted
         stock is presented to the Company's transfer agent for registration or
         transfer in connection with any sales theretofore made under rule 144,
         provided such certificate is duly endorsed for transfer by the
         appropriate person(s) or accompanied by a separate stock power duly
         executed by the appropriate person(s) in each case with reasonable
         assurances that such endorsements are genuine and effective, and is
         accompanied by an opinion of counsel satisfactory to the Company and
         its counsel and that such transfer has complied with the requirements
         of rule 144, as the case may be, the Company will promptly instruct
         its transfer agent to register such transfer and to issue one or more
         new certificates representing such shares to the transferee and, if
         appropriate under the provisions of rule 144, as the case may be, free
         of any stop transfer order or restrictive legend.

                 5.03     New Directorships.  BH shall have the right to
         nominate one (1) person to serve as a director of the Company;
         provided that such person shall be mutually satisfactory to BH and the
         Company.

                 5.04     Future Obligations.  The Company covenants to:

                 (a)      Retain as auditors to the Company a "big six"
         accounting firm for purposes of auditing the Company's future
         financial statements commencing with the December 31, 1997, financial
         statements;

                 (b)      Create an advisory board of professional advisors who
         shall be selected in conjunction with BH; and

                 (c)      Retain a public relations firm with national
         marketing experience and provide a maximum annual budget of $30,000
         for public relations expense.

<PAGE>   26
                 (d)      Require all directors to be either a shareholder or
         option holder of the Company.

                 5.05     Company's Indemnification.  The Company will
         indemnify and hold harmless BH and Kirk Blosch and Jeff Holmes,
         individually, from and against any and all losses, claims, damages,
         expenses, liabilities, or actions to which any of them may become
         subject under applicable law (including the Securities Act and the
         Securities Exchange Act) and will reimburse them for any legal or
         other expenses reasonably incurred by them in connection with
         investigating or defending any claims or actions, whether or not
         resulting in liability, insofar as such losses, claims, damages,
         expenses, liabilities, or actions arise out of or are based upon any
         untrue statement or alleged untrue statement of material fact
         contained in any application or statement filed with a governmental
         body or arising out of or are based upon the omission or alleged
         omission to state therein a material fact required to be stated
         therein, or necessary in order to make the statements therein not
         misleading, but only insofar as any such statement or omission was
         made in reliance upon and in conformity with information furnished in
         writing by the Company expressly for use therein.  Subject to Section
         5.07 herein, the indemnity agreement contained herein shall remain
         operative and in full force and effect, regardless of any
         investigation made by or on behalf of BH, Kirk Blosch and Jeff Holmes.

                 5.06     BH's Indemnification.  BH will indemnify and hold
         harmless the Company and its directors and officers, and each person,
         if any, who controls the Company within the meaning of the Securities
         Act, from and against any and all losses, claims, damages, expenses,
         liabilities, or actions to which any of them may become subject under
         applicable law (including the Securities Act and the Securities
         Exchange Act) and will reimburse them for any legal or other expenses
         reasonably incurred by them in connection with investigating or
         defending any claims or actions, whether or not resulting in
         liability, insofar as such losses, claims, damages, expenses,
         liabilities, or actions arise out of or are based upon any untrue
         statement or alleged untrue statement of material fact contained in
         any application or statement filed with a governmental body or arising
         out of or are based upon the omission or alleged omission to state
         therein a material fact required to be stated therein, or necessary in
         order to make the statements therein not misleading, but only insofar
         as any such statement or omission was made in reliance upon and in
         conformity with information furnished in writing by BH expressly for
         use therein.  Subject to Section 5.07 herein, the indemnity agreement
         contained herein shall remain operative and in full force and effect,
         regardless of any investigation made by or on behalf of the Company.

                 5.07     Expiration of Covenants.  The covenants contained in
         this Article V shall expire when BH, together with Kirk Blosch, an
         individual residing in the State of Utah, and Jeff W. Holmes, an
         individual residing in the State of Arizona, no

         longer holds at least six and one-half percent (6.5%) of the then
         outstanding voting securities of the Company.

         2.      BH hereby acknowledges that the previous assignment of the
warrants included only an assignment of the registration rights of such
warrants and no other rights in Article V of the Agreement.

         3.      This Amendment shall terminate in the event that, prior to 
December 31, 1997, the Company fails to close a public offering of its Common 
Stock with net proceeds to the Company of at least $15 million.

         4.      This Amendment is and shall be binding upon and inure to the
benefit of the Parties hereto and their respective successors, assigns, and
personal representatives.

         5.      If any provision of the Amendment is deemed by a court of
competent jurisdiction to be invalid and contrary to any existing or future
law, such invalidity shall not impair the operation of the remaining provisions
of the Amendment.

         6.      This Amendment, together with the Agreement, constitutes the
entire agreement of the Parties with respect to the subject matter hereof and
supersedes any prior oral or written agreements with respect to the subject
matter contained herein.

         7.      This Amendment shall be construed in accordance with and
governed by the laws of the State of Utah without regard to the conflict of
laws.

         IN WITNESS WHEREOF, the Parties have executed this Amendment to be
effective as of the date and year first written above.  This Amendment may be
signed in counterparts, all of which together shall constitute one and the same
instrument.
