                                  THE COMPANY
 
   
     SeaMED Corporation (the "Company" or "SeaMED") is a leading manufacturer of
advanced medical instruments for medical technology companies. SeaMED
manufactures durable electronic medical instruments for its customers, often as
part of systems that also include single-use components. To assist its customers
in developing and commercializing their instruments for manufacture by SeaMED,
the Company provides a wide range of engineering services and regulatory
expertise. In its last fiscal year, SeaMED manufactured or engineered
instruments for many established medical technology companies, including Arrow
International, Inc., Becton, Dickinson and Company, Boston Scientific
Corporation, C.R. Bard, Inc., Guidant Corporation, Johnson & Johnson,
Physio-Control Corporation, Sorin Biomedical Inc., St. Jude Medical, Inc. and
United States Surgical Corporation. SeaMED's customers also include many
emerging medical technology companies such as Aksys Ltd., ArthroCare
Corporation, Biofield Corp., CellPro, Incorporated, Gynecare, Inc., Optical
Sensors Incorporated, ReSound Corporation and Urologix, Inc. The Company has
been profitable in each of its last five years with revenues growing from $8.7
million in fiscal year 1992 to $26.1 million in fiscal year 1996, a compound
annual growth rate of 32%. During this period, the number of manufactured
instruments grew from seven to 23.
    
 
   
     Since 1988, SeaMED has focused its business primarily on manufacturing
medical instruments and believes it is the largest independent manufacturer of
advanced medical instruments for medical technology companies. As part of its
growth strategy, SeaMED continues to expand its engineering expertise,
regulatory knowledge and manufacturing capabilities, thereby allowing it to
design and manufacture a broader range of medical instruments. SeaMED also
utilizes its resources and expertise by accepting high value-added engineering
and manufacturing contracts for select nonmedical products.
    
 
   
     The demand for health care has grown rapidly in recent years, including
demand for medical instruments that can lessen the overall cost of health care
while improving patient outcomes. As medical instruments have incorporated the
latest developments in computers, electronics, materials and other technologies,
and medical technology companies have sought to comply with increasingly
stringent regulatory requirements, 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 medical technology industry has
increased. As a result, many medical technology companies increasingly are
focusing their resources on certain critical functions and outsourcing others.
SeaMED believes that the trend toward outsourcing engineering and manufacturing
of durable medical instruments is in its early stages and will expand
significantly.
    
 
     SeaMED provides complete solutions to meet its customers' needs for
instrument engineering, prototyping, preproduction and volume manufacturing.
SeaMED offers its customers the following advantages:
 
        -  Broad experience in product development, engineering, manufacturing
           and regulatory compliance for advanced medical instruments
 
        -  Reduction of fixed capital and personnel commitments for noncore
           functions
 
        -  Demand-driven production flexibility
 
        -  In-place resources to shorten time-to-market
 
        -  FDA and ISO 9001 compliant manufacturing facilities
 
   
        -  Integrated engineering and manufacturing, improving quality and
           reducing costs

                                  RISK FACTORS
 
     In addition to the other information contained in this Prospectus, the
following risk factors should be considered carefully in evaluating the Company
and its business before purchasing shares of Common Stock offered by this
Prospectus. This Prospectus contains, in addition to historical information,
forward-looking statements that involve risks and uncertainties. The Company's
actual results could differ materially from the results discussed in the
forward-looking statements. Factors that could cause or contribute to such
differences include those discussed below, as well as those discussed elsewhere
in this Prospectus.
 
CUSTOMER RISK FACTORS
 
   
     SeaMED's success depends on the success of its customers and their
instruments manufactured by SeaMED. Any unfavorable developments or adverse
effects on the sales of those products or its customers' businesses, results of
operations or financial condition could have a corresponding adverse effect on
SeaMED. SeaMED believes that its customers and their products (and, accordingly,
SeaMED) are generally subject to the following risks:
    
 
     Competitive Environment
 
     The medical products industry is highly competitive and subject to
significant technological change, and 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 SeaMED'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 SeaMED's customers may succeed in developing or marketing technologies and
products that will be more accepted in the marketplace than the instruments
manufactured by SeaMED for its customers or that would render its customers'
technology and products obsolete or noncompetitive. In addition, other
competitors may develop alternative treatments or cures so that the need for the
instruments manufactured by SeaMED could be reduced or eliminated. Many of
SeaMED'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. SeaMED's 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
dramatic drop in product sales, which would have an adverse effect on the
Company's business, results of operations and financial condition. See
"Business -- Industry Overview."
 
     Customer Regulatory Compliance
 
   
     The Food and Drug Administration (the "FDA") regulates instruments
manufactured by SeaMED under the Federal Food, Drug, and Cosmetic Act, as
amended (the "FDC Act"), which requires certain clearances or approvals from the
FDA before new medical devices can be marketed. As a prerequisite to any
introduction of a new device into the medical marketplace, SeaMED's customers
must obtain necessary product clearances or approvals from the FDA or other
regulatory agencies with applicable jurisdiction. There can be no assurance that
SeaMED's customers will obtain such clearances or approvals on a timely basis,
if at all.
    
 
   
     Certain medical instruments manufactured by SeaMED may be subject to the
need to obtain FDA approval of a premarket approval application ("PMA"), which
requires substantial preclinical and clinical testing and may cause delays and
prevent introduction of such instruments. Currently, nine of SeaMED's customers
are seeking or plan to seek PMA for instruments to be manufactured by SeaMED.
FDA marketing approval regulations depend heavily on administrative
interpretations, which may change retroactively and
    
 
                                        5
<PAGE>   7
 
   
may create additional barriers that prevent or delay the introduction of a
product. Marketing approval for PMA products could be denied altogether if
clinical testing does not establish that the product is safe and effective.
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 PMA approval are frequent, and, in
turn, could result in delaying or canceling customer orders from SeaMED. Many
products never receive PMA approval. Once FDA approval is obtained, a new
approval, in the form of a PMA supplement, may be needed to modify the device,
its intended use, or its manufacturing. Discovery of product problems may result
in restrictions on the product's future use or withdrawal of the product from
the market despite prior governmental approval. In 1991, one of the Company's
customers recalled its disposable product, and postponed all purchases of the
related instrument from SeaMED, which had an adverse effect on the Company's
results of operations. There can be no assurance that product recalls, product
defects or loss of necessary regulatory approvals will not occur in the future.
The delays and potential product cancellations inherent in the development,
regulatory approval, commercialization and ongoing regulatory compliance of
instruments manufactured by the Company may have a material adverse effect on
the Company's business, reputation, results of operations and financial
condition.
    
 
   
     Sales of SeaMED-manufactured medical instruments outside the United States
are subject to regulatory requirements that vary widely from country to country.
The time required to obtain approval for sale in foreign countries may be longer
or shorter than that required for FDA approval, 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 the European Community, SeaMED's customers will want
their products to qualify for distribution under the "CE mark," which
qualification enables certain medical products to move freely within the
European Community. 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, SeaMED'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 SeaMED's customers will
obtain all required clearances or approvals for exported products on a timely
basis, if at all. Failure or delay in obtaining the requisite regulatory
approvals for exported instruments manufactured by the Company may have an
adverse effect on the Company's business, results of operations and financial
condition.
    
 
     Medical instruments manufactured by SeaMED and marketed by its customers
pursuant to FDA clearances or approvals are subject to pervasive and continuing
regulation by the FDA and certain state and foreign regulatory agencies.
Regulatory approvals 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. Product approvals
could be withdrawn for failure to comply with regulatory standards or the
occurrence of unforeseen problems following initial marketing. 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 an adverse effect on the Company's business, 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 a 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 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."
 
                                        6
<PAGE>   8
 
     Uncertain Market Acceptance of Products; Product Obsolescence
 
     There can be no assurance that SeaMED's customers' products will gain any
significant market acceptance and market share among physicians, patients and
health care payors, even if required regulatory approvals are obtained. Market
acceptance may depend on a variety of factors, including educating physicians
regarding the use of a new procedure, overcoming physician 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 SeaMED'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. Many of SeaMED'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.
SeaMED's customers may be unable to establish effective sales and marketing and
distribution channels to successfully commercialize their products.
 
     In addition, the marketplace for medical products is characterized by rapid
change and technological innovation. As a result, SeaMED and its customers are
subject to the risk of product obsolescence, whether from long 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
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 an instrument manufactured by SeaMED would result in the
Company's having to reduce production volumes or to discontinue manufacturing
the instrument, which could have an adverse effect on the Company's business,
results of operations and financial condition. See "Business -- Industry
Overview."
 
     Customers' Future Capital Requirements
 
   
     Many of SeaMED's customers, especially emerging medical technology
companies, are not profitable and may have little or no revenues, but they have
significant working capital requirements, for which the customer 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 SeaMED's revenues or
profitability, any adverse effect on a customer resulting from insufficient
funds could result in an adverse effect on the Company's business, results of
operations and financial condition.
    
 
     Uncertainty of Third-Party Reimbursement
 
     Sales of many of the instruments manufactured by SeaMED 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 SeaMED's customers to achieve market acceptance of
their products. Without adequate support from third-party payors, the market for
the products of SeaMED's customers may be limited.
 
VARIABILITY OF OPERATING RESULTS
 
     SeaMED'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. In the past, changes
 
                                        7
<PAGE>   9
 
in customer orders have had a significant effect on SeaMED's results of
operations. Further, SeaMED's contracts with its customers typically have no
minimum purchase requirements. As a result, production may be reduced or
discontinued at any time, causing substantial sales fluctuations from quarter to
quarter or from year to year. Other factors that may adversely affect SeaMED's
annual and quarterly results of operations include inexperience in manufacturing
a particular instrument, inventory shortages or obsolescence, labor costs or
shortages, price competition and regulatory requirements. Because SeaMED'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. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations."
 
CUSTOMER CONCENTRATION
 
   
     Historically, a substantial percentage of SeaMED's net sales have been to
fewer than 10 customers, the loss of any of which would adversely affect the
Company's business, results of operations and financial condition. In each of
the fiscal years ended June 30, 1995 and June 30, 1996, five of the Company's
customers (not all the same in each year) together represented 49% and 41% of
revenues, respectively. If one or more of SeaMED's customers experiences
exceptional growth relative to other SeaMED customers, then SeaMED's success
could become substantially more dependent on the continued success of such
customer, and any unfavorable development regarding such customer or its product
could result in a material adverse effect on the Company's business, results of
operations and financial condition. Similarly, if one or more of SeaMED's
customers were to seek and obtain price discounts from the Company for that
customer's instruments, the resulting lower gross margins on those instruments
may have an adverse effect on the Company's overall results of operations. In
addition, if any customer with which SeaMED does a substantial amount of
business were to encounter financial distress, the customer's unwillingness or
inability to pay its obligation to the Company could result in a material
adverse effect on the Company's results of operations and financial condition.
    
 
   
     SeaMED's sales to Coinstar, Inc. ("Coinstar"), a nonmedical customer for
which SeaMED manufactures a coin-counting machine that exchanges loose coins for
currency, represented approximately 25% of SeaMED's revenues for the quarter
ended September 30, 1996. SeaMED currently manufactures these machines under a
nonexclusive manufacturing agreement with Coinstar that allows Coinstar to
cancel or modify orders with SeaMED on 90 days' notice. An order cancellation or
modification by Coinstar could result in an adverse effect on the Company's
business, results of operations and financial condition. See "Management's
Discussion and Analysis of Financial Condition and Results of
Operations -- Results of Operations" and "Business -- Customers and Products."
    
 
COMPETITION
 
   
     SeaMED faces competition from current and prospective customers who
evaluate SeaMED's capabilities against the merits of designing, engineering and
manufacturing instruments internally. SeaMED also faces competition from design
firms and other manufacturers that operate in the medical technology industry.
Most of SeaMED's customers have substantially greater financial and research and
development resources than SeaMED and either operate internal design and
manufacturing facilities or have sufficient resources to develop internal design
and manufacturing capabilities. As a result of the consolidation of smaller
manufacturers into larger manufacturers, some existing or prospective customers
may be eliminated. In the future, SeaMED may also compete against new entrants
to the industry. For example, a medical technology company with design and
manufacturing capabilities (especially one with excess capacity) could decide to
compete with SeaMED for outsource development and manufacturing of medical
instruments. In addition, several large electronic contract manufacturers and
defense department contractors with extensive engineering expertise may from
time to time undertake design and/or manufacture of medical instruments.
Although the Company is not aware of substantial competition from these
noncustomer sources to date, there can be no assurance that these or other
formidable competitors will not aggressively expand into the Company's targeted
    
 
                                        8
<PAGE>   10
 
   
market segment in the future. Competition from any of the foregoing sources
could place pressure on SeaMED 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. See
"Business -- Competition"
    
 
UNCERTAINTY OF MARKET ACCEPTANCE OF OUTSOURCING MANUFACTURE OF MEDICAL
INSTRUMENTS
 
     SeaMED believes that the market for outsourcing the manufacture of advanced
medical instruments for medical technology companies is in its early stages.
SeaMED's engineering and manufacturing activities require that customers provide
SeaMED 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 outsourcing engineering or manufacturing
are too great or exceed the anticipated benefits of outsourcing. In addition,
medical technology companies that have previously made substantial investments
to establish design and manufacturing capabilities may be reluctant to outsource
those functions. If the medical technology industry generally, or any
significant existing or potential customer, concludes that the disadvantages of
outsourcing manufacturing outweigh the advantages, SeaMED could suffer a
substantial diminution in the size of its target market, which would have a
material adverse effect on its business, results of operations and financial
condition.
 
COMPLIANCE WITH REGULATORY AGENCY REQUIREMENTS
 
     SeaMED is subject to a variety of regulatory agency requirements in the
United States and foreign countries relating to the instruments that it
manufactures for its customers. The process of obtaining and maintaining
required regulatory approvals and otherwise remaining in regulatory compliance
in the United States and certain other countries is lengthy, expensive and
uncertain.
 
   
     Applicable law requires that SeaMED comply with the FDA's detailed good
manufacturing practices ("GMP") regulations for the manufacture of medical
products. The FDA monitors compliance with its GMP regulations by subjecting
medical product manufacturers to periodic FDA inspections of their manufacturing
facilities. The FDA has recently revised the GMP regulations. The new
regulations include authority for the FDA to regulate the design phase as well
as the manufacture of medical products and make a number of other significant
changes in the requirements applicable to manufacturers. To ensure compliance
with GMP requirements, SeaMED 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.
SeaMED 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 an adverse effect on the willingness of customers and
prospective customers to do business with SeaMED. In order for the Company's
instruments to be exported and for SeaMED and its customers to be qualified to
use the CE mark, the Company maintains International Organization for
Standardization ("ISO") 9001/EN 46001 certification, which subjects SeaMED'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.
    
 
     SeaMED also is 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 SeaMED has not been the subject of any
material proceeding
 
                                        9
<PAGE>   11
 
concerning such laws and believes it is currently in compliance with such laws
in all material respects, there can be no assurance that SeaMED 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 SeaMED 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 or financial condition. There can be
no assurance that the Company will not be required to incur significant costs to
comply with applicable laws and regulations in the future or that such laws and
regulations will not have a material adverse effect on the Company's business,
results of operations or financial condition. See "Business -- Quality Assurance
and Regulatory Compliance" and "Business -- Governmental Regulation."
 
PRODUCT RECALLS, PRODUCT LIABILITY AND INSURANCE
 
     Many of the instruments SeaMED designs or manufactures are life-sustaining,
life-supporting or implantable medical products. The tolerance for error in the
design, manufacture or use of these products may be small or nonexistent. If an
instrument 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 instrument 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 the 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.
 
   
     The manufacture and sale of the medical instruments manufactured by SeaMED
involve the risk of product liability claims. Although SeaMED generally obtains
indemnification from its customers for instruments it manufactures to the
customers' specifications and in addition maintains product liability insurance,
there can be no assurance that the indemnities will be honored or the coverage
of the Company's insurance policies will be adequate. In addition, SeaMED
generally provides a design defect warranty and indemnifies its customers for
failure of an instrument to conform to design specifications and against defects
in materials and workmanship. SeaMED intends to evaluate its insurance coverage
from time to time in view of developments in its business and products currently
under development. Product liability insurance is expensive and in the future
may not be available on acceptable terms, in sufficient amounts, or at all. 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 and for
which indemnification was not available could have a material adverse effect on
the Company's business, results of operations and financial condition. See
"Business -- Quality Assurance and Regulatory Compliance."
    
 
DEPENDENCE ON KEY PERSONNEL
 
   
     SeaMED's future success depends to a significant extent on the continued
service of certain of its key managerial, technical and engineering personnel,
particularly its President and Chief Executive Officer, W. Robert Berg, and its
continuing ability to attract, train, assimilate and retain highly qualified
engineering, technical and managerial personnel experienced in commercializing
medical products. Competition for such personnel is intense, the available pool
of qualified candidates is limited and there can be no assurance that SeaMED can
retain its key engineering, technical and managerial personnel or that it can
attract, train, assimilate or retain other highly qualified engineering,
technical and managerial personnel in the future. The loss of Mr. Berg or any of
SeaMED's other key personnel or the inability of SeaMED to hire, train,
assimilate or retain qualified 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 has an employment agreement with the Company. The
Company has obtained key-man life insurance policies on the life of W. Robert
Berg in the amount of $2 million. See "Management."
    
 
                                       10
<PAGE>   12
 
MANAGEMENT OF GROWTH
 
   
     SeaMED's ability 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. If SeaMED cannot keep
pace with the growth of its customers, it may lose customers and its growth may
be limited. In particular, to accommodate future growth SeaMED may need to
obtain additional space to continue manufacturing at optimum levels. SeaMED
currently obtains additional manufacturing space based on its projected needs,
which are based on, but do not necessarily reflect, its customers' production
forecasts. As a result, the Company may from time to time have insufficient
manufacturing facilities to fulfill on a timely basis unexpected and significant
increases in customer orders. Although an existing manufacturing facility for
PMA products may be able to be expanded without prior regulatory approval,
establishing a new manufacturing facility for PMA products requires prior
regulatory approval, which may cause production delays. The Company could lose
customer business or miss growth opportunities in the future if it were unable
to obtain adequate additional space on a timely basis. Conversely, if one or
more customers were to cancel production orders, the Company may incur
substantial lease obligations, resulting in excess production capacity, which
could have a material adverse effect on the Company's business, results of
operations and financial condition.
    
 
   
     SeaMED's business, both operationally and administratively, depends on
SeaMED's ability to store, retrieve, process, manage and share significant
amounts of information. In addition, SeaMED depends on its computer system to
integrate its manufacturing processes with its quality assurance procedures
(including, for example, maintaining distribution records and allowing for the
tracing of certain product lots) to comply with GMP requirements and ISO 9001
standards. Although SeaMED believes that its existing computer system will
adequately serve its near-term needs, it may need to upgrade its computer system
if significant growth continues. Any difficulties or delays in upgrading the
computer system, or in remaining in compliance with applicable GMP requirements
and ISO 9001 standards, could adversely affect the manufacture and delivery of
customer instruments, and the Company's management, reporting and internal
control systems.
    
 
     The Company's failure to manage growth effectively could have a material
adverse effect on its business, results of operations and financial condition.
 
AVAILABILITY OF COMPONENT PARTS
 
   
     SeaMED relies on third-party suppliers for each of the component parts used
in manufacturing its customers' instruments. Although component parts are
generally available from multiple suppliers, certain component parts may require
long lead times, and SeaMED may have to delay the manufacture of customer
instruments from time to time due to the unavailability of certain component
parts. Component shortages for a particular instrument may adversely affect the
Company's ability to satisfy customer orders for that instrument. At various
times, there have been shortages of component parts, especially electronics
components. If shortages of component parts should occur, the Company may be
forced to pay higher prices for affected components or delay manufacturing and
shipping particular instruments, either of which could adversely affect customer
demand for such instruments and the Company's business, results of operations
and financial condition.
    
 
CUSTOMER CONFLICTS
 
   
     The medical technology industry reflects vigorous competition among its
participants, sometimes leading to substantial animosity between competitors.
SeaMED's growth may be adversely affected if its customers require SeaMED to
enter into noncompetition agreements that prevent SeaMED from manufacturing
instruments for its customers' competitors. For example, if SeaMED enters into a
noncompetition agreement, SeaMED may be adversely affected if its customer's
product is not successful and SeaMED must forgo an opportunity to manufacture a
successful instrument for such customer's competitor. Any conflicts among its
customers could prevent or deter SeaMED 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
 
   
     SeaMED 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 12 to 24 months (depending primarily on SeaMED's growth rate and its
results of operations). Thereafter, SeaMED 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 acceptable to SeaMED. Any additional equity
financing would result in additional dilution to the Company's shareholders,
including shareholders who purchase Common Stock in this offering. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations."
    
 
CONTROL BY MANAGEMENT
 
   
     Following this offering, the current executive officers and directors of
SeaMED and their affiliates will beneficially own or have voting control over
approximately 43.5% of the outstanding Common Stock (approximately 41.3% 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 to effectively control 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" and "Description of Capital Stock."
    
 
ABSENCE OF PRIOR MARKET; POTENTIAL VOLATILITY OF COMMON STOCK PRICE
 
   
     Prior to this offering, there has been no public market for the Common
Stock, and there can be no assurance that an active trading market will develop
or be sustained. The initial public offering price for the Common Stock will be
determined by negotiations between the Company and the representatives of the
Underwriters and may not be indicative of the market price of the Common Stock
after this offering. See "Underwriting." 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

SHARES ELIGIBLE FOR FUTURE SALE
 
   
     Sales of substantial amounts of Common Stock in the public market after
this offering could adversely affect the market price of the Common Stock. Of
the 4,969,128 shares outstanding following this offering, the 1,850,000 shares
sold hereby will be freely tradable in the public market and the remaining
3,119,128 shares will be "restricted securities" within the meaning of Rule 144
promulgated under the Securities Act of 1933, as amended (the "Securities Act").
Approximately 159,639 restricted securities will be eligible for sale
immediately following this offering in reliance on Rule 144(k) under the
Securities Act. Approximately 8,558 restricted securities will be eligible for
sale 90 days following this offering in reliance on other provisions of Rule 144
and on Rule 701. Beginning 180 days after the closing of this offering,
following the expiration of certain lockup agreements among the Underwriters,
the Selling Shareholders, the Company's officers and directors and certain other
shareholders of the Company, 2,628,598 additional currently outstanding shares
of Common Stock will be eligible for sale in the public market, subject to the
limitations of Rule 144 and Rule 701. If the Securities and Exchange Commission
(the "Commission") adopts proposed amendments to Rule 144 to substantially
reduce required holding periods for restricted securities, another 295,666
currently outstanding shares of Common Stock will be eligible for sale in the
public market as described in the preceding sentence. In addition, certain
shareholders, representing approximately 2,555,637 shares of Common Stock, have
the right, subject to certain conditions, to include their shares in future
registration statements relating to SeaMED's securities and to cause SeaMED to
register certain shares of Common Stock owned by them. An additional 39,066
shares of Common Stock issuable upon exercise of an outstanding warrant and
586,617 shares of Common Stock reserved for issuance pursuant to the Company's
stock option

plans (the "Option Shares"), may become eligible for resale in the public market
at various times after the expiration of the 180-day lockup period. The holders
of 154,700 Option Shares which have vested and are not subject to lockup
agreements could exercise their options and sell these shares in compliance with
Rule 701 beginning 90 days after the effective date of this 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."
    
 
DILUTION
 
     Purchasers of the Common Stock offered hereby will incur immediate and
substantial dilution in the net tangible book value per share of the Common
Stock from the assumed initial public offering price. See "Dilution."
 
ABSENCE OF DIVIDENDS
 
     The Company has never paid dividends on the Common Stock and does not
anticipate paying any such dividends in the foreseeable future. See "Dividend
Policy."

                                USE OF PROCEEDS
 
   
     The net proceeds to the Company from the sale of 1,361,942 shares of Common
Stock offered hereby are estimated to be approximately $13.0 million
(approximately $15.9 million if the Underwriters' over-allotment option is
exercised in full), after deducting estimated underwriting discounts and
offering expenses and assuming an initial public offering price of $11.00 per
share.
    
 
     The Company intends to use a portion of such net proceeds to repay bank
debt consisting of a bank line of credit and three notes payable, the aggregate
outstanding balance of which is expected to be between $3.5 million and $5.0
million, and approximately $1.8 million of the net proceeds to pay cumulative
dividends on Class A and Class D Preferred Stock. See "Management's Discussion
and Analysis of Financial Condition and Results of Operations -- Liquidity and
Capital Resources." The Company intends to use the remaining net proceeds to
fund working capital needs and for general corporate purposes, including
leasehold improvements and purchases of equipment. The Company, if the
opportunity arises, may use an unspecified portion of the net proceeds to
acquire other businesses or assets that complement the Company's existing
business. The Company currently is not engaged in any discussions regarding such
acquisitions and has no plans, arrangements, understandings or agreements
regarding any specific acquisition.
 
     Pending the uses set forth above, the net proceeds will be invested in
short-term, investment-grade, interest-bearing securities. The Company will not
receive any proceeds from the sale of Common Stock by the Selling Shareholders.
See "Principal and Selling Shareholders."
 
                                DIVIDEND POLICY
 
   
     The Company has never paid dividends on the Common Stock, and currently
intends to retain all earnings for use in the expansion of its business, and
does not anticipate paying any dividends on the Common Stock in the foreseeable
future. In addition, the Company's current revolving credit facility prohibits
the payment of dividends, but such restriction has been waived for the payment
of cumulative dividends on Class A and Class D Preferred Stock upon the closing
of this offering.

                                    DILUTION
 
   
     The Company's pro forma net tangible book value as of September 30, 1996
was approximately $5.3 million, or $1.46 per share. Pro forma net tangible book
value per share represents the Company's total assets less intangible assets and
total liabilities divided by the number of shares outstanding, adjusted on a pro
forma basis for the (i) conversion into Common Stock of all outstanding shares
of Preferred Stock and (ii) pro forma accrual of $1.7 million of cumulative
dividends on Class A and D Preferred Stock as of September 30, 1996. Without
taking into account any changes in such net tangible book value per share after
September 30, 1996, other than to give effect to the sale of the shares of
Common Stock offered by the Company hereby at an assumed initial public offering
price of $11.00 per share and the receipt of the estimated net proceeds of such
sale, the pro forma net tangible book value per share as of September 30, 1996
would have been approximately $18.4 million, or $3.69 per share. This represents
an immediate increase in net tangible book value per share of $2.23 to existing
shareholders and an immediate dilution of $7.31 per share to new investors. The
following table sets forth this per share dilution:

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
     The following discussion and analysis should be read in conjunction with
the Company's Financial Statements and Notes thereto and other financial
information included elsewhere in this Prospectus. This Prospectus contains, in
addition to historical information, forward-looking statements that involve
risks and uncertainties. The Company's actual results could differ materially
from the results discussed in the forward-looking statements. Factors that could
cause or contribute to such differences include those discussed below, as well
as those discussed elsewhere in this Prospectus. See "Risk Factors."
 
OVERVIEW
 
   
     SeaMED is a leading manufacturer of advanced medical instruments for
medical technology companies. SeaMED was incorporated in 1976, and since 1988
has focused its business primarily on manufacturing medical instruments for
medical technology companies. To assist its customers in developing and
commercializing their products for manufacture by SeaMED, the Company provides a
wide range of engineering services and regulatory expertise. The Company has
been profitable in each of its last five fiscal years, with revenues growing
from $8.7 million in fiscal year 1992 to $26.1 million in fiscal year 1996, a
compound annual growth rate of 32%.
    
 
   
     SeaMED's manufacturing contracts with its customers are usually exclusive
contracts for a fixed period of time, generally ranging from three to five
years. SeaMED negotiates each manufacturing contract independently, and each
varies as to profitability. SeaMED negotiates the price of each manufactured
instrument on a cost and margin formula. SeaMED's contracts with its customers
generally permit annual manufacturing cost audits and price renegotiations.
During the contract term, customers have broad discretion to control the volume
and timing of instrument deliveries. Consequently, SeaMED's revenues with
respect to each instrument may vary substantially from period to period, and an
instrument that generates revenues in one quarter may not necessarily generate
revenues in each quarter of a fiscal year. In addition, for a variety of reasons
such as a customer's inventory levels, sales mix and timing of product launches,
SeaMED's revenues for an instrument do not necessarily correspond to the
customer's sales.
    
 
     Manufacturing revenue growth depends primarily on two factors: increased
demand for instruments manufactured by SeaMED and SeaMED's ability to attract
additional manufacturing contracts from emerging and established medical
technology companies. SeaMED has no ability to increase demand for the
instruments it manufactures because SeaMED's customers control all product
marketing and sales. SeaMED markets its manufacturing capabilities and usually
procures additional manufacturing contracts as a result of its engineering
projects, but the volume and timing of future manufacturing revenues that relate
to any specific engineering project are highly variable, and certain engineering
projects may not lead to future manufacturing revenues. The manufacturing gross
margin percentage from year to year depends primarily on the product mix, as
gross margins vary by instrument and as a result of negotiated volume discounts.
Management may negotiate volume discounts if the larger volume results in
smaller per unit overhead allocation, thereby improving operating margin. For
manufacturing revenues from instruments not yet approved for commercial use
(known as "preproduction revenues"), the gross margin percentage is generally
lower because a smaller number of units limits opportunities to achieve
economies of scale, and the instrument and its manufacturing process are being
refined.
 
   
     SeaMED provides its customers with engineering services at any stage of an
instrument's development, as part of its strategy to obtain exclusive
manufacturing rights for an instrument. SeaMED generally provides engineering
services under a project plan that identifies the engineering tasks,
deliverables and schedule. SeaMED negotiates each engineering project plan
independently, and, as a business strategy, generally prices engineering
contracts to cover direct project expenses (i.e., nonrecurring engineering
expenses) plus a share of marketing, general and administrative expenses.
SeaMED's objective in providing engineering services is to obtain, for a
specific time period (usually three to five years), exclusive manufacturing
rights to the instrument resulting from the engineering project. The customer
can typically cancel the engineering project at any time upon short notice.

     Engineering revenues are derived primarily from professional services
provided by SeaMED's engineers. The balance of engineering revenues is sales of
materials to customers at cost. Engineering revenue growth depends primarily on
three factors: (i) the number and scope of existing engineering projects, (ii)
whether existing projects are in time-intensive phases, and (iii) whether new
engineering projects of sufficient scope replace engineering projects that are
completed or otherwise terminated. Engineering gross margins are low due to
SeaMED's strategy of pricing engineering services as part of an exclusive
manufacturing contract for the resulting instrument. Since demand for
engineering services varies widely, SeaMED may experience from time to time
excess engineering capacity. Engineering margins may fluctuate depending on the
rates that customers pay under engineering project plans and the utilization
rates of engineers.
    
 
   
     SeaMED has historically designed, developed and manufactured certain
proprietary instruments. SeaMED expects that fiscal year 1997 will be the last
year in which it derives revenues from such instruments. SeaMED thereafter will
derive its revenues exclusively by manufacturing instruments for its customers.
SeaMED's revenues from its proprietary instruments were $1.2 million, $923,000,
$1.4 million and $451,000 in fiscal years 1994, 1995 and 1996 and the first
quarter of fiscal year 1997, respectively.
    
 
     Marketing, general and administrative expenses include the costs of
SeaMED's marketing, finance, and management information systems departments and
other administrative costs. In addition, marketing, general and administrative
expenses include the cost of a Company-wide bonus tied to operating performance.

     Manufacturing revenues increased by approximately $3.2 million from the
first quarter of fiscal year 1996 to the first quarter of fiscal year 1997, due
primarily to a new nonmedical product manufactured for Coinstar under a
nonexclusive contract, new medical instruments and increased volume of existing
medical instruments, adding approximately $4.4 million in the aggregate. SeaMED
began sales to Coinstar in the fourth quarter of fiscal year 1996, and sales to
Coinstar in the first quarter of fiscal year 1997 represented approximately
25.0% of total revenues and approximately 33.5% of manufacturing revenues. See
"Risk Factors -- Customer Concentration" and "Business -- Customers and
Products." This aggregate increase was offset by decreased volume of certain
existing medical instruments and the phase-out of other medical instruments,
which decreased revenues by approximately $1.2 million in the aggregate.
Significant manufacturing revenues were generated by 11 medical instruments in
the first quarter of fiscal year 1996 and 12 medical instruments and one
nonmedical product in the first quarter of fiscal year 1997. Engineering
revenues increased by approximately $1.8 million from the first quarter of
fiscal year 1996 to the first quarter of fiscal year 1997, due primarily to new
projects, increased time being billed on existing projects and increased hourly
rates for engineering services, adding approximately $2.2 million in the
aggregate. This increase was offset by the transition of certain projects from
engineering to manufacturing and other projects being delayed or cancelled,
which decreased engineering revenues by approximately $410,000 in the aggregate.

</TABLE>
    
 
   
     Manufacturing gross margin decreased from 21.5% of manufacturing revenues
in the first quarter of fiscal year 1996 to 19.1% in the first quarter of fiscal
year 1997, due primarily to a negative gross margin (loss) on a medical
instrument that will be phased out of full production in the second quarter of
fiscal year 1997 and a negative gross margin on an instrument in preproduction.
The decrease from the fiscal year 1996 manufacturing gross margin percentage of
23.6% to a manufacturing gross margin percentage of 19.1% in the first quarter
of fiscal year 1997 was primarily attributable to the same negative gross
margins. Management expects the fiscal year 1997 manufacturing gross margin
percentage to be lower than the fiscal year 1996 manufacturing gross margin
percentage of 23.6%. Engineering gross margin increased from 3.1% of engineering
revenues in the first quarter of fiscal year 1996 to 11.9% in the first quarter
of fiscal year 1997. This increase reflects a trend of increasing engineering
gross margin percentages, due primarily to (i) spreading certain fixed
engineering costs over a higher revenue base, (ii) better utilization of
engineers, and (iii) increased hourly rates for engineering services. Management
expects the fiscal year 1997 engineering gross margin percentage to be near 10%.
    
 
   
     Marketing, General and Administrative Expenses
    
 
   
     Marketing, general and administrative expenses increased from $491,000 in
the first quarter of fiscal year 1996 to $847,000 in the first quarter of fiscal
year 1997, but as a percentage of revenues decreased from 9.9% to 8.4% for the
respective quarters (9.1% and 6.2%, respectively, before Company-wide bonus
accruals). The decrease in marketing, general and administrative expenses as a
percentage of revenues is due to increased revenues without a proportionate
increased commitment of marketing, general and administrative resources.

     Manufacturing revenues increased by approximately $5.8 million from fiscal
year 1995 to fiscal year 1996, due primarily to new instruments and a nonmedical
product and increased volume of existing instruments, adding approximately $7.6
million in the aggregate. This increase was offset by decreased volume of
certain existing instruments and the phase-out of other instruments, which
decreased revenues by approximately $1.8 million in the aggregate. Although 18
and 23 instruments contributed to manufacturing revenues in fiscal years 1995
and 1996, respectively, significant manufacturing revenues were generated by 12
instruments in fiscal year 1995 and 13 instruments and one nonmedical product in
fiscal year 1996. Engineering revenues increased by approximately $2.7 million
from fiscal year 1995 to fiscal year 1996, due primarily to new projects,
increased time being billed on existing projects and increases in hourly rates
for engineering services, adding approximately $5.1 million in the aggregate.
This increase was offset by the transition of certain projects from engineering
to manufacturing and other projects being delayed or cancelled, which decreased
revenues by approximately $2.4 million in the aggregate.
    
 
   
     Manufacturing revenues increased by approximately $1.9 million from fiscal

ing revenues in fiscal year 1994, significant manufacturing revenues were
generated by nine instruments in fiscal year 1994. Engineering revenues
increased by approximately $1.0 million from fiscal year 1994 to fiscal year
1995, due primarily to new projects, increased time being billed on existing
projects and increases in hourly rates for engineering services, adding
approximately $3.3 million in the aggregate. This increase was offset by the
transition of certain projects from engineering to manufacturing and other
projects being delayed or cancelled, which decreased revenues by approximately
$2.3 million in the aggregate.
    
 
     Price adjustments under existing manufacturing contracts have not been
significant. Increases in revenues have not been significantly influenced by
inflation.

</TABLE>
 
   
     Manufacturing gross margin increased from 21.9% of manufacturing revenues
in fiscal year 1995 to 23.6% in fiscal year 1996, due primarily to changes in
the product mix to higher gross margin products, including a decrease in the
percentage of manufacturing revenues derived from products in preproduction.
Engineering gross margin as a percentage of engineering revenues has increased
from 8.0% in fiscal year 1995 to 10.2% in fiscal year 1996. This trend was due
primarily to (i) spreading certain fixed engineering costs over a higher revenue
base, (ii) better utilization of engineers, and (iii) increased hourly rates for
engineering services.
    
 
   
     Manufacturing gross margin decreased from 24.8% in fiscal year 1994 to
21.9% in fiscal year 1995, due primarily to changes in the product mix to
lower-margin products, including an increase of the percentage of manufacturing
revenues derived from products in preproduction. Engineering gross margin as a
percentage of engineering revenues increased from 5.6% in fiscal year 1994 to
8.0% in fiscal year 1995 for the reasons stated above.

     Marketing, general and administrative expenses increased by approximately
$1.0 million from fiscal year 1995 to fiscal year 1996, due primarily to
increased Company-wide bonuses and increased management information systems
costs. Marketing, general and administrative expenses before bonuses represented
10.0% and 8.5% of revenues in fiscal years 1995 and 1996, respectively, as fixed
costs were spread over a higher revenue base. If anticipated revenue growth
occurs, SeaMED expects marketing, general and administrative expenses as a
percentage of revenues to decline in the near term.

     Marketing, general and administrative expenses did not change significantly
from fiscal year 1994 to fiscal year 1995 because the number of employees in the
relevant departments remained substantially the same. Marketing, general and
administrative expenses before bonuses represented 11.7% of revenues in fiscal
year 1994.

</TABLE>
    
 
   
     The $960,000 increase in operating income from fiscal year 1995 to fiscal
year 1996 is due primarily to an increase in both manufacturing volume and the
manufacturing gross margin percentage. In addition, engineering volume and gross
margins improved. These improvements were offset by the increase in marketing,
general and administrative expenses, the most significant of which was the
Company-wide bonus.
    
 
   
     The increase in operating income from fiscal year 1994 to fiscal year 1995
was due primarily to increased revenues.
    
 
     Income Taxes
 
   
     The Company's effective tax rate was 35% in fiscal year 1996 and 18.9% in
fiscal year 1995. A tax benefit of $208,500 was recorded in fiscal year 1994.
Differences from the federal statutory income tax rate of 34% for fiscal years
1994 and 1995 resulted primarily from the use of net operating loss
carryforwards and tax credits and the reversal of valuation allowances due to
changes in the estimate of realizable deferred tax assets. The Company expects
the future effective tax rate to stabilize at a rate that approximates the
federal statutory rate of 35%.
    
 
   
  QUARTERLY OPERATING DATA
    
 
     Changes in customer orders have had a significant effect on SeaMED's
results of operations. The volume and timing of customer orders may vary due to
(i) variation in demand for customer 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. Production may be reduced
or discontinued at any time, causing sales fluctuations from quarter to quarter.
SeaMED's business organization and its related cost structure anticipate
supporting a certain minimum level of revenues. The Company, therefore, has a
limited ability to adjust its short-term cost structure, which compounds
quarterly fluctuations.

LIQUIDITY AND CAPITAL RESOURCES
 
   
     SeaMED has historically financed its operations through earnings, debt and
sales of securities. Net cash provided by operating activities was approximately
$658,000 in fiscal year 1995 compared to net cash used in operating activities
of approximately $296,000 in fiscal year 1996, with the change being due
primarily to the need to use increased fiscal year 1996 earnings to finance a
large increase in net working capital. Net cash used in operating activities was
$1.0 million in fiscal year 1994 compared to net cash provided by operating
activities of $658,000 in fiscal year 1995, with the change being due primarily
to a smaller increase in inventory and accounts receivable in fiscal year 1995.
    
 
   
     SeaMED has a zero-balance cash management arrangement with Pacific
Northwest Bank (the "Bank"). Under this arrangement, the amount outstanding
under SeaMED's line of credit fluctuates daily based on the Company's receipts
and disbursements. Under the line of credit, SeaMED can borrow up to 80% of
eligible accounts receivable (less than 60 days outstanding) to a maximum of
$4.0 million. Borrowings under the line bear interest at the Bank's prime rate
plus .25% (8.5% at September 30, 1996) and are secured by receivables and
inventories. The line is subject to annual approval and extension by December 1
of each year. At September 30, 1996, SeaMED had drawn approximately $2.2 million
against the $4.0 million limit.
    
 
   
     In addition to the line of credit, SeaMED has three notes payable to the
Bank, each of which requires monthly payments including interest and is secured
by a lien on the Company's equipment. One such note bears interest at a rate of
8.5%, requires monthly payments of approximately $19,000, is due on August 5,
1998, and at September 30, 1996 had an outstanding balance of approximately
$392,000. The second such note bears interest at a rate of 8.75%, requires
monthly payments of approximately $15,000, is due on November 5, 1999, and at
September 30, 1996 had an outstanding balance of approximately $492,000. The
third such note bears interest at a rate of 8.75%, requires monthly payments of
approximately $12,000, is due on July 5, 2000, and at September 30, 1996 had an
outstanding balance of approximately $484,000.
    
 
     At September 30, 1996, total indebtedness to the Bank, including the line
of credit and the three notes payable, was approximately $3.6 million. SeaMED
anticipates using a portion of the net proceeds of this offering to repay all
outstanding indebtedness to the Bank.
 
   
     In addition to borrowings from the Bank, SeaMED also has an unsecured
subordinated note payable to Cordis Corporation, with an interest rate
adjustment on each July 1 to the prime rate plus 2% (10% at September 30, 1996),
with a maximum rate of 10% and a minimum rate of 7%. The note is due in monthly
payments of $17,000 through May 2001. At September 30, 1996, the balance
outstanding on this note was approximately $751,000.

<PAGE>   26
 
   
     To accommodate anticipated future growth, SeaMED will need additional
sources of capital to fund working capital needs for inventory and accounts
receivable, to lease and acquire equipment for additional plant facilities and
to make other capital expenditures. In addition to repaying indebtedness to the
Bank, SeaMED expects to use a portion of the net proceeds of this offering to
pay a cumulative preferred dividend of approximately $1.8 million, to fund
working capital needs and for general corporate purposes, including leasehold
improvements and purchases of equipment. SeaMED believes that the net proceeds
of this offering, together with existing capital resources and amounts available
under its existing line of credit with the Bank, will satisfy the Company's
anticipated capital needs for the next 12 to 24 months (depending primarily on
SeaMED's growth rate and its results of operations). Capital expenditures were
$876,000 in fiscal year 1994, $1.2 million in fiscal year 1995 and $1.5 million
in fiscal year 1996. Following this offering, SeaMED will review the adequacy of
its line of credit.
    
 
     SeaMED leases two buildings under long-term leases with an aggregate of
approximately 81,000 square feet, which require annual lease payments of
approximately $900,000. In September 1996, SeaMED entered into a lease for an
additional 90,000 square feet of space for a term of 10 years with two five-year
renewal options. When fully occupied (anticipated to be by January 1, 1999), the
annual lease payment on this space will be approximately $1.2 million.
 
     There can be no assurance that appropriate sources of capital will be
available in the future or, if available, will be on terms acceptable to the
Company. See "Risk Factors -- Future Capital Requirements."

INTRODUCTION
 
   
     SeaMED is a leading manufacturer of advanced medical instruments for
medical technology companies. SeaMED manufactures durable electronic medical
instruments for its customers, often as part of systems that also include
single-use components. To assist its customers in developing and commercializing
their instruments for manufacture by SeaMED, the Company provides a wide range
of engineering services and regulatory expertise. In its last fiscal year,
SeaMED manufactured or engineered medical instruments for many established
medical technology companies, including Arrow International, Inc., Becton,
Dickinson and Company, Boston Scientific Corporation, C.R. Bard, Inc., Guidant
Corporation, Johnson & Johnson, Physio-Control Corporation, Sorin Biomedical
Inc., St. Jude Medical, Inc. and United States Surgical Corporation. SeaMED's
customers also include many emerging medical technology companies such as Aksys
Ltd., ArthroCare Corporation, Biofield Corp., CellPro, Incorporated, Gynecare,
Inc., Optical Sensors Incorporated, ReSound Corporation and Urologix, Inc. The
Company has been profitable in each of its last five years with revenues growing
from $8.7 million in fiscal year 1992 to $26.1 million in fiscal year 1996, a
compound annual growth rate of 32%. During this period, the number of
manufactured instruments grew from seven to 23.
    
 
   
     Since 1988, SeaMED has focused its business primarily on manufacturing
medical instruments and believes it is the largest independent manufacturer of
advanced medical instruments for medical technology companies. As part of its
growth strategy, SeaMED continues to expand its engineering expertise,
regulatory knowledge and manufacturing capabilities, thereby allowing it to
design and manufacture a broader range of medical instruments. SeaMED also
utilizes its existing resources and expertise by accepting high value-added
engineering and manufacturing contracts for select nonmedical products.
    
 
INDUSTRY OVERVIEW
 
   
     Demand for health care has grown rapidly in recent years, and is expected
to continue to increase as the population ages. Advancements in science,
medicine, and computers have dramatically expanded the number and variety of
effective medical procedures. The most advanced medical procedures and
techniques, many of which use advanced medical instruments, 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 would be reimbursed, demand has grown for the medical instruments and
systems needed for these procedures. More recently, in response to increasing
pressure to control rising health care costs, medical technology companies have
developed advanced medical instruments and systems that improve patient outcomes
and lessen the overall cost of health care by reducing palliative care and acute
hospital stays.
    
 
   
     As medical products have incorporated the latest developments in computers,
electronics, materials and other 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 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, reduce
costs, maintain or increase market share and accelerate realization of revenue.
    
 
   
     At the same time, the FDA and the European Community have adopted
increasingly stringent and evolving regulatory requirements for the manufacture
of medical products. In the United States, certain medical products are subject
to the FDA's PMA requirements and many medical products require premarket
clearance. In addition, products are subject to regulation with respect to
manufacture, labeling, distribution, postmarket reporting and promotion. Under
European 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 invest significant
financial resources to establish and maintain manufacturing facilities that
comply with the FDA's GMP requirements and the European Community's quality
system standards, particularly if the facilities produce life-supporting,
life-sustaining, or implantable products. After the often lengthy and
time-consuming process of obtaining FDA marketing authorization and ISO
certification, medical technology companies must devote substantial managerial
oversight to ensure continued compliance with FDA and European Community
requirements.
    
 
                                       26
<PAGE>   28
 
   
     SeaMED believes that the trend toward outsourcing medical product
engineering and manufacturing is in its early stages and outsourcing revenues
represent a very small percentage of the more than $30 billion medical
technology industry. SeaMED also believes that medical technology companies will
expand their outsourcing of engineering and manufacturing and that SeaMED is
well positioned for such expansion. With intensified competition, higher initial
product development costs and longer product development and regulatory cycles,
many of SeaMED's customers have chosen to concentrate product development and
manufacturing resources on higher-volume single-use components and to outsource
the development and manufacturing of durable medical instruments.
    
 
THE SEAMED ADVANTAGES
 
   
     SeaMED provides integrated solutions to the engineering, regulatory and
manufacturing challenges of advanced medical instruments. SeaMED offers its
customers the following advantages:
    
 
   
        -  Broad Experience With Numerous Advanced Medical Instruments. Since
           1992, SeaMED has manufactured 21 different advanced medical
           instruments that incorporate diverse technologies, and it currently
           has an additional 14 instruments or systems in the engineering design
           phase. As a result, SeaMED has developed considerable expertise in
           solving its customers' product development, engineering,
           manufacturing and regulatory issues.
    
 
        -  Focus on Core Functions. By relying on SeaMED's engineering and
           manufacturing capabilities, customers can focus management efforts on
           product research, clinical development and sales and marketing, as
           well as manufacturing their higher-volume, single-use components. In
           addition, SeaMED's customers can shift to variable costs the high
           fixed costs associated with staffing and maintaining GMP compliant
           facilities for durable medical instruments.
 
   
        -  Production Flexibility. SeaMED's broad customer base permits it to
           offer its customers production flexibility, which enables customers
           to adjust production volumes in response to fluctuations in market
           demand or regulatory issues.
    
 
   
        -  Rapid Product Development. SeaMED believes that, with its engineering
           and manufacturing capabilities, it can more rapidly develop and
           manufacture new products at a lower overall cost than its customers,
           which otherwise expend significant time and financial resources to
           develop internal engineering expertise, establish GMP-qualified
           manufacturing facilities and obtain ISO certification.
    
 
   
        -  Regulatory Compliant Manufacturing. SeaMED's medical manufacturing
           facilities are ISO 9001/EN 46001 certified and SeaMED believes that
           they comply with GMP requirements. SeaMED currently manufactures six
           medical instruments that are regulated as Class III instruments,
           which is the most stringent FDA regulatory category. Due to the
           critical nature of regulatory compliance, SeaMED devotes significant
           management time and financial resources to GMP compliance and ISO
           certification.
    
 
        -  Integrated Engineering and Manufacturing. SeaMED provides a wide
           range of engineering services, and has the capabilities to provide
           complete instrument or system design (including engineering, testing,
           component analysis and regulatory compliance), which enhances its
           manufacturing business. By integrating engineering design work with
           manufacturing processes, materials acquisitions and quality and
           regulatory considerations, SeaMED believes that it can increase the
           quality and lower the overall cost of the instruments that it
           manufactures for its customers. Since 1992, SeaMED's engineering
           staff has performed substantially all the engineering design work for
           15 medical instruments.
 
CUSTOMERS AND PRODUCTS
 
   
     SeaMED's customers include some of the world's largest medical technology
companies as well as many emerging medical technology companies. As of September
30, 1996, SeaMED was manufacturing 18 medical instruments for 18 customers and
was engaged in the engineering design phase of 14 instruments for 11
    
 
                                       27
<PAGE>   29
 
   
customers. In fiscal year 1996, revenues from one customer, C.R. Bard, Inc.,
accounted for more than 10% of the Company's revenues. SeaMED negotiates
separate contracts with its customers for engineering design services and
product manufacturing. Most projects begin with an engineering design contract.
As a business strategy, SeaMED generally prices engineering contracts to cover
direct project expenses (i.e., nonrecurring engineering expenses) plus a share
of operating expenses. SeaMED's objective is to obtain the exclusive
manufacturing rights to medical instruments for a specific time period,
generally three to five years. SeaMED believes that no customer has replaced
SeaMED as its manufacturer.
    
 
   
     The following list identifies certain customers with instruments currently
being designed or manufactured by SeaMED, the product description and the
product status. The instruments and projects included in this list represented
in the aggregate 66.7% of SeaMED's revenues for fiscal year 1996.

     SeaMED from time to time selectively designs and manufactures nonmedical
commercial products that benefit from SeaMED's engineering and manufacturing
capabilities. Currently, SeaMED manufactures one such product, a coin-counting
machine that exchanges loose coins for currency, for Coinstar which represented
approximately 25% of SeaMED's revenues for the quarter ended September 30, 1996.
SeaMED currently manufactures these machines under a nonexclusive manufacturing
agreement with Coinstar that allows Coinstar to cancel or modify orders with
SeaMED on 90 days' notice. SeaMED believes its experience in manufacturing the
large and complex Coinstar machine has expanded its manufacturing expertise.
SeaMED also has one engineering contract to design one other nonmedical product.
SeaMED intends to maintain as its primary focus the design and manufacturing of
advanced medical instruments for medical technology companies. See "Risk
Factors -- Customer Concentration" and "-- Management of Growth."
    
 
ENGINEERING
 
   
     SeaMED will provide its customers with engineering services at any stage of
an instrument's development. Customers in many cases rely on SeaMED for complete
instrument design (including engineering, testing, component analysis and
regulatory compliance). Since 1992, SeaMED's engineering staff has performed
substantially all of the engineering design work for 15 instruments. Customers,
however, often deliver final drawings for instruments they believe ready for
manufacturing. In such cases, SeaMED reviews and tests the existing design prior
to manufacturing the instrument and, in many cases, SeaMED's engineers are able
to identify and offer alternatives to the customer's design that improve
performance or produce manufacturing efficiencies.
    
 
     SeaMED approaches each engineering project using a team structure, each
team being a multi-disciplinary collection of engineers and technicians who
understand the technical requirements of the particular project. Each team
includes representatives from other engineering disciplines, including one or
more manufacturing, test and quality engineers, who help design an instrument
that can be manufactured in a manner that meets or exceeds customer
specifications and applicable regulatory requirements.
 
   
     SeaMED integrates its engineering staff throughout its operations,
including sales and marketing, customer relations, materials management, quality
assurance, regulatory compliance and manufacturing. SeaMED's engineers play a
critical role in sales and marketing by assisting SeaMED's Vice President, Sales
and Marketing, in evaluating requests for proposals and developing
project-specific, solution-oriented responses, bids, cost estimates and project
plans. Similarly, SeaMED project engineers act as customer contacts throughout
the engineering design phase and have responsibility for all aspects of a
customer's project, including coordinating the component parts necessary for the
instrument, quality assurance procedures, regulatory compliance and the
manufacturing process. SeaMED has made significant investments in state-of-
the-art equipment to support its engineering design effort, including
engineering design and testing stations and computer-aided design software.
    
 
   
     Each instrument, product design, patent and other proprietary right
developed by SeaMED becomes the property of the customer, with SeaMED typically
retaining the manufacturing rights to such instrument for a period generally
ranging from three to five years. Generally, SeaMED provides nonrecurring
engineering services under a project plan that identifies the engineering tasks,
deliverables and schedule. Typically, such services are billed on a time and
materials basis and are cancelable at any time. The project plan usually states
that SeaMED is intended to be the manufacturer of the instrument, but does not
specify the manufacturing terms. SeaMED typically provides a design defect
warranty for 15 months to replace or repair instruments relating to the specific
elements for which SeaMED had primary design responsibility.

     At September 30, 1996, SeaMED's engineering staff consisted of 56 engineers
employed by SeaMED and 19 consulting or contract engineers. The engineering
staff includes a variety of disciplines, as follows:

MANUFACTURING OPERATIONS
 
     As the engineering project nears completion, the members of the project
team with direct responsibility for manufacturing, quality assurance,
manufacturing/test engineering and materials assume a greater role. The team
implements a materials management system and develops an assembly process and
product testing and quality assurance procedures to produce high-quality
instruments that satisfy customer specifications as well as GMP and ISO 9001
quality standards. Often, manufacturing begins with a relatively small number of
preproduction units, which are used by the customer for clinical trials. SeaMED
and the customer frequently make engineering and manufacturing refinements
during the preproduction phase.
 
     Each instrument is manufactured in a dedicated manufacturing cell on the
Company's manufacturing floor. At September 30, 1996, SeaMED had 19 cells in
operation. These cells are flexible and can be expanded or modified as needed,
enabling SeaMED to adjust production volumes quickly in response to customer
orders.
 
   
     SeaMED's customers generally submit purchase orders for delivery of
instruments in future periods. The Company does not regard backlog data as a
meaningful indicator of revenues for future periods because of its policy of
generally allowing its customers to cancel orders at any time without notice.
    
 
     SeaMED uses a fully integrated materials requirements system. This system,
which includes sales order entry, purchasing, inventory control, production
control, and cost accounting, helps SeaMED manage material acquisitions and
inventory for the various projects in full production at any one time and
facilitates the planning and control essential to building products within
critical time schedules.
 
   
     Manufacturing contracts are generally executed near completion of the
engineering project, at which time SeaMED and the customer negotiate the term,
pricing, warranty, indemnity and other provisions. Pricing typically is based on
SeaMED's expected cost and an agreed-upon margin, both of which are subject to
customer audit. Although manufacturing contracts rarely include minimum
production requirements, they typically grant SeaMED exclusive manufacturing
rights for periods generally ranging from three to five years. Contracts
typically are terminable only for cause, which generally is defined as the
failure to deliver instruments on a timely basis or the failure to comply with
design specifications. In each case, SeaMED usually has an opportunity to cure
the breach. SeaMED generally warrants conformity to design specifications and
against defects in materials and workmanship and indemnifies its customers
against losses arising out of a breach of such warranty. In addition, SeaMED in
many cases enters into repair and service agreements with its customers that set
forth the pricing and terms under which SeaMED provides repair and replacement
parts, and needed services and upgrades not covered under warranty. Although
most of SeaMED's manufacturing is performed under long-term manufacturing
contracts, five instruments, with revenues for the fiscal year ended June 30,
1996 totaling approximately $6.9 million, are manufactured only under purchase
orders. SeaMED, however, currently is negotiating master manufacturing contracts
with customers of four of such instruments.
    
 
QUALITY ASSURANCE AND REGULATORY COMPLIANCE
 
   
     SeaMED emphasizes quality throughout its operations and integrates its
quality assurance and quality engineering programs throughout each instrument's
engineering and manufacturing phases, a process that
    
 
                                       30
<PAGE>   32
 
involves SeaMED's senior management and executive officers. At September 30,
1996, SeaMED employed 37 personnel in its quality assurance, quality engineering
and regulatory departments, 10 of whom are engineers.
 
   
     Quality assurance procedures are integrated into every aspect of an
instrument's manufacturing cycle. SeaMED establishes a quality assurance program
for each instrument, which includes a "zero defects" objective. Substantially
all component parts and outside-contracted product subassemblies receive a
control number and are inspected and, if necessary, tested. On the manufacturing
floor, quality assurance personnel implement quality procedures at interim
points during the assembly process and conduct a final-level 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.
    
 
     SeaMED is registered with the FDA as a medical device manufacturer. As a
manufacturer of instruments reviewed under the PMA process, SeaMED is subject to
inspections by the FDA prior to PMA. SeaMED 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 "-- Governmental Regulation."
 
   
     In 1994, SeaMED received ISO 9001/EN 46001 certification. ISO 9000 is the
first quality system standard to gain worldwide recognition, including in the
European Community, Japan and the United States. As many medical technology
companies expand sales of products in international markets, compliance with
international quality standards has increased in importance. SeaMED's ISO 9001
designation is the highest level of ISO 9000 certification and indicates that
SeaMED has met design, manufacture and test standards for its products. SeaMED's
EN 46001 designation indicates that it has met additional standards specific to
medical instruments.
    
 
   
     SeaMED's ISO 9001/EN 46001 certification serves as a marketing tool that
enhances SeaMED'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 process.
    
 
SALES AND MARKETING
 
     SeaMED generates new business opportunities by promoting its engineering
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 parties familiar with SeaMED's services. While
SeaMED's sales and marketing department consists solely of the Vice President,
Sales and Marketing, other executive officers and project engineers participate
extensively in sales and marketing activities. SeaMED believes it can
effectively market and sell its engineering and manufacturing capabilities while
maintaining a small sales and marketing staff.
 
COMPETITION
 
     For established medical technology companies, SeaMED's primary competitor
is the internal design and manufacturing facilities of its prospective customer.
For emerging companies, SeaMED competes both with the customer's internal design
and manufacturing facilities (planned or operational), other manufacturers that
operate in the medical technology industry and, to a lesser extent, with
specialty design firms, most of which do not have manufacturing capabilities.
The primary competitive factors in medical instrument design and manufacturing
include quality, regulatory compliance, technical engineering competence, cost
of the nonrecurring engineering design component, price of the manufactured
product, experience, customer service, and ability to meet a design and
production schedule.
 
   
     Competition is primarily limited to those companies that meet the minimum
applicable regulatory requirements of the FDA and international manufacturing
and design standards. In the future, SeaMED is likely to compete against new
entrants into the industry as outsourcing 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 nonmedical engineering expertise may undertake design and/or
manufacture of medical instruments. Although SeaMED is not aware of substantial
competition from these sources to date, there can
    
 
                                       31
<PAGE>   33
 
   
be no assurance that these, or other formidable, competitors will not
aggressively expand into SeaMED's targeted market segment in the future.
    
 
GOVERNMENTAL REGULATION
 
     SeaMED's business and operations are subject to substantial governmental
regulation, primarily from the FDA in the United States and the regulatory
bodies in other countries, as described below. While these regulations directly
affect SeaMED's design and manufacturing operations, to a greater extent they
affect SeaMED's customers and their products. To the extent that production of a
customer's instrument is delayed or cancelled due to regulatory noncompliance,
the timing and levels of revenues received by SeaMED may be affected adversely.
 
     United States
 
   
     Because SeaMED provides design and manufacturing services to producers of
medical devices, SeaMED's manufacturing facilities are subject to extensive
regulation by the FDA under the 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 FDC Act requires PMA approval before certain medical
devices can be marketed. Noncompliance with FDA regulations can result in, among
other things, SeaMED and its customer being subject to fines, injunctions, 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 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 SeaMED.
    
 
   
     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 standards
and guidelines). Generally, Class III devices are higher-risk devices and cannot
be marketed until after receiving FDA PMA approval. Currently, 12 instruments of
SeaMED's customers are Class III devices that require PMA approval prior to
commercialization, two of which have received such approval.
    
 
   
     A premarket approval 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 submission must include the
proposed labeling. Although SeaMED's services do not extend to assistance with
testing, studies and human clinical trials, SeaMED 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 can affect the timing of manufacturing
services provided by SeaMED. 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 receives PMA approval, it
cannot be sold commercially in the United States. After PMA approval is
obtained, subsequent modifications to the device 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, 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) process. Currently, five of SeaMED's customers have submitted or
intend to submit a request to the FDA for clearance for marketing under a
    
 
                                       32
<PAGE>   34
 
   
510(k) notification for devices to be manufactured by SeaMED. 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.
    
 
   
     Any instrument manufactured by SeaMED or distributed by its customers
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. Device
manufacturers are required to register their establishments and list their
devices with the FDA and 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 SeaMED with respect to
manufacturing and quality assurance activities. The FDA has changed the GMP
regulations. Among other things, the new regulations will require design
controls and maintenance of service records. SeaMED believes that the new
regulations will not substantially increase SeaMED's cost of complying with GMP
requirements. SeaMED currently has implemented training and procedural changes
with respect to the changes to GMP. The failure to be found in compliance with
the GMP regulations would result in 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, results of operations and financial condition.
    
 
     International
 
   
     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 may 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 Community. SeaMED received in, and has maintained
since, June 1994 ISO 9001/EN 46001 certification. If a SeaMED customer is also
ISO 9001 certified, the customer may be permitted to affix the CE mark to an
instrument manufactured by SeaMED 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 barriers.
    
 
EMPLOYEES AND LABOR RELATIONS
 
     As of September 30, 1996, SeaMED employed a total of 226 people and

STOCK PLANS
 
     1988 Stock Option Plan
 
   
     The SeaMED Corporation 1988 Stock Option Plan (the "1988 Plan") permits the
grant of options to purchase an aggregate of 680,000 shares of Common Stock to
regular full-time officers and key employees of the Company. The 1988 Plan is
administered by the Board of Directors, which generally has the authority to
select individuals who are to receive options and to specify the terms and
conditions of each option so granted, including the number of shares covered by
the option, the type of option (incentive or nonqualified), the exercise price
(which must be at least equal to the fair market value of the Common Stock on
the date of grant with respect to incentive stock options), the vesting
provisions and the option term. Unless otherwise provided by the Board of
Directors, any option granted under the 1988 Plan expires on the date set forth
in the optionee's option agreement or, if earlier, (i) the date specified in the
option agreement following an optionee's termination of service with the
Company, but not later than 12 months after such termination, other than
termination for cause, in which case the option terminates immediately, (ii) 12
months after the optionee's death or disability, or (iii) on various specified
dates in the event of a merger, consolidation, tender offer, takeover bid, sale
of assets or majority vote of the shareholders of the Company in favor of
dissolving, subject to reinstatement if such event does not occur.
    
 
     As of September 30, 1996, options to purchase 293,383 shares of Common
Stock granted under the 1988 Plan had been exercised, options to purchase
385,179 shares were outstanding and 1,438 shares remained available for grant.
 
     1995 Employee Stock Option and Incentive Plan
 
     The purpose of the SeaMED Corporation 1995 Employee Stock Option and
Incentive Plan (the "1995 Plan") is to offer incentives and awards to those
employees, agents and consultants of the Company who are key to the Company's
growth, development and financial success, thereby aligning the personal
interests of such persons, through the ownership of Common Stock and other
incentives, with those of the Company's shareholders. The 1995 Plan combines the
features of an incentive and a nonqualified stock option plan, a stock award
plan and a stock appreciation rights ("SAR") plan. The 1995 Plan is a long-term
incentive compensation plan and is designed to provide a competitive and
balanced incentive and reward program for participants. A total of 200,000
shares of Common Stock is available under the 1995 Plan, of which, as of
September 30, 1996, options to purchase 105,020 shares had been granted and
options to purchase 94,980 shares were available for future grant; no options
have been exercised.
 
     Terms of Stock Option Grants.  The Compensation Committee has the authority
to select individuals who are to receive options under the 1995 Plan and to
specify the terms and conditions of each option so granted (incentive or
nonqualified), the exercise price (which must be at least equal to the fair
market value
 
                                       37
<PAGE>   39
 
of the Common Stock on the date of grant with respect to incentive stock options
and options awarded to nonemployee directors), the vesting provisions and the
option term.
 
   
     Stock Awards.  The Compensation Committee is authorized under the 1995 Plan
to issue shares of Common Stock to eligible participants upon such terms and
conditions and subject to such limitations, if any (including, without
limitation, restrictions based upon the achievement of specific business
objectives, tenure, and other measures of individual or business performance),
and/or restrictions under applicable federal or state securities laws, and
conditions under which the same shall lapse, as the Compensation Committee may
determine. As of September 30, 1996, the Company had granted no such awards.
    
 
     Stock Appreciation Rights.  A SAR is an incentive award that permits the
holder to receive (per share covered thereby) the amount by which the fair
market value of a share of Common Stock on the date of exercise exceeds the fair
market value of such share on the date the SAR was granted. The Compensation
Committee may grant SARs independently or in tandem (such that the exercise of
the SAR or related stock option will result in forfeiture of the right to
exercise the related stock option or SAR for an equivalent number of shares)
with a stock option award. The Compensation Committee is authorized under the
1995 Plan to determine the times of exercise of granted SARs and their times of
expiration, which may not exceed 10 years. As of September 30, 1996, the Company
had granted no SARs.
 
     1996 Employee Stock Purchase Plan
 
   
     The Company has reserved an aggregate of 70,000 shares of Common Stock for
issuance under the SeaMED Corporation 1996 Employee Stock Purchase Plan (the
"ESPP"). The ESPP is intended to qualify under Section 423 of the Internal
Revenue Code of 1986, as amended, and permits eligible employees of the Company
(unless otherwise waived by the Board of the Directors, all employees who have
been employed by the Company for at least six months, except employees whose
customary employment is less than 20 hours per week and employees whose
customary employment is for not more than five months in any calendar year) to
purchase Common Stock through payroll deductions of up to 10% of their
compensation, provided that no employee may purchase Common Stock worth more
than $25,000 in any calendar year. The ESPP will be implemented with 10
consecutive six-month purchase periods, the first such purchase period to
commence upon the date that the Common Stock begins to trade on the Nasdaq Stock
Market and to end on June 30, 1997. Thereafter, purchase periods shall commence
on each subsequent January 1 and July 1. The price of Common Stock purchased
will be 85% of the lesser of the fair market value of the Common Stock on the
first day of the purchase period and the fair market value of the Common Stock
on the last day of the purchase period. The ESPP will expire on December 31,
2001. No shares have been issued under the ESPP.

rate of interest set by the Internal Revenue Service from time to time. Mr. Berg
may prepay principal and interest at any time without penalty; unpaid principal
and interest are due on October 11, 2000. As of September 30, 1996, aggregate

5,082,704, and 1,465,000 shares of Class A, B, C and D Preferred Stock,
respectively. The designations of rights and preferences with respect to the
Preferred Stock generally provides for liquidation, conversion, redemption,
voting and other rights. Holders of Class A and D Preferred Stock are entitled
to cumulative annual dividends of $0.10 and $0.08, respectively. All shares of
outstanding Preferred Stock will be converted automatically into an aggregate of
2,934,029 shares of Common Stock upon the closing of this offering. Upon such
closing, holders of Class A
 
                                       41
<PAGE>   43
 
   
and D Preferred Stock are entitled to all cumulative dividends to the time of
such conversion, which were approximately $1.7 million as of September 30, 1996.
    
 
   
     Pursuant to SeaMED's Articles of Incorporation, the Board of Directors is
authorized to issue 5,000,000 shares of the Undesignated Preferred Stock in one
or more classes or series, or both, and, without further approval of the
shareholders, to fix dividend rights and terms, conversion rights, voting
rights, redemption rights and terms, liquidation preferences and any other
rights, preferences, privileges and restrictions applicable to each class or
series of Undesignated Preferred Stock. The issuance of Undesignated Preferred
Stock, while providing flexibility in connection with possible acquisitions and
other corporate purposes, could, among other things, adversely affect the voting
power of the holders of Common Stock and, under certain circumstances, make it
more difficult for a third party to gain control of the Company, discourage bids
for Common Stock at a premium or otherwise adversely affect the market price of
the Common Stock. The Company has no current plans to issue any Undesignated
Preferred Stock.
    
 
WARRANT
 
     The investment banking firm of Allen & Company Incorporated acted as
placement agent with respect to the sale of Class D Preferred Stock. As partial
compensation for such services, it received, and beneficially owns, a warrant to
purchase 39,066 shares of Common Stock at a price of $4.70 per share.
 
REGISTRATION RIGHTS
 
     Pursuant to certain agreements between the Company and certain purchasers
of capital stock (collectively, the "Holders"), who will hold approximately
2,555,637 shares of Common Stock (the "Registerable Securities") following this
offering, the Holders are entitled to certain rights with respect to
registration of such shares under the Securities Act. The Holders include R.
Scott Asen, each of the Pioneer Entities and Geocapital Ventures. If the Company
proposes to register any of its securities, with certain exceptions that include
a registration relating solely to employee benefit plans, either for its own
account or the account of other security holders, the Company is required to
notify the Holders and to use its best efforts to effect the registration, and
the Holders are entitled to include at the Company's expense their Registerable
Securities in such registration, subject to certain conditions and limitations.
In addition, at any time after the first anniversary of the closing of this
offering, the Holders may require the Company to file a registration statement
under the Securities Act at the Company's expense, and the Company is required
to use its best efforts to effect such registration, subject to certain
conditions and limitations.
 
CERTAIN PROVISIONS OF ARTICLES OF INCORPORATION AND BYLAWS
 
     Shareholder Action by Written Consent; Special Meetings of Shareholders
 
     The Company's Bylaws permit any action required or permitted to be taken by
the Company's shareholders to be effected at a duly called annual or special
meeting of shareholders or by unanimous consent in writing. Additionally, the
Articles of Incorporation and Bylaws require that special meetings of the
shareholders of the Company may be called only by a majority of the Board of
Directors or an authorized committee thereof.
 
     Advance Notice Requirements for Shareholder Proposals and Director
Nominations
 
     The Company's Bylaws provide that shareholders seeking to bring business
before or to nominate directors at any meeting of shareholders must provide
timely notice thereof in writing. To be timely, a shareholder's notice must be
delivered to, or mailed and received at, the principal executive offices of the
Company not less than (i) with respect to an annual meeting, 120 calendar days
in advance of the one-year anniversary of the date that the Company's proxy
statement was released to shareholders in connection with the previous year's
annual meeting, except that if no annual meeting was held in the previous year
or if the date of the annual meeting has been changed by more than 30 calendar
days from the date contemplated at the time of the previous year's proxy
statement, such notice must be received by the Company a reasonable time before
the Company's proxy statement is to be released and (ii) with respect to a
special meeting of
 
                                       42
<PAGE>   44
 
shareholders, a reasonable time before the Company's proxy statement is to be
released. The Bylaws also specify certain requirements for a shareholder's
notice to be in proper written form. These provisions may preclude some
shareholders from bringing matters before the shareholders or from making
nominations for directors.
 
     Director and Officer Indemnification
 
     The Washington Business Corporation Act (the "Washington Business Act")
provides that a Washington corporation may include provisions in its articles of
incorporation relieving each of its directors of monetary liability arising out
of his or her conduct as a director for breach of his or her fiduciary duty,
except liability for (i) acts or omissions of a director finally adjudged to be
intentional misconduct or a knowing violation of law, (ii) conduct in violation
of Section 23B.08.310 of the Washington Business Act (which section relates to
unlawful distributions), or (iii) any transaction with respect to which it is
finally adjudged that a director personally received benefit in money, property
or services to which the director was not legally entitled. The Company's
Articles of Incorporation include such provisions.
 
     The Company's Articles of Incorporation and Bylaws provide that the Company
shall, to the fullest extent permitted by law, indemnify and advance expenses to
each of its currently acting and former directors and officers, and may so
indemnify and advance expenses to each of its current and former employees and
agents. The Company believes that the foregoing provisions are necessary to
attract and retain qualified persons as directors and officers. Prior to
consummation of this offering, the Company intends to enter into separate
indemnification agreements with each of its directors and executive officers in
order to effectuate such provisions.
 
PROVISIONS AFFECTING ACQUISITIONS AND BUSINESS COMBINATIONS
 
   
     The Washington Business Act contains certain provisions that may have the
effect of delaying or discouraging a hostile takeover of the Company. Chapter
23B.19 of the Washington Business Act prohibits a target corporation, with
certain exceptions, from engaging in certain significant business transactions
(such as a merger or sale of assets) with a person or group of persons which
beneficially acquires 10% or more of the corporation's voting securities (an
"Acquiring Entity") for a period of five years after such acquisition, unless
the transaction is approved by a majority of the members of the target
corporation's board of directors prior to the date of the transaction. An
Acquiring Entity is further prohibited from engaging in significant business
transactions with the target corporation unless the per share consideration paid
to holders of outstanding shares of common stock and other classes of stock of
the target corporation meet certain minimum criteria. These provisions may have
the effect of delaying, deterring or preventing a change in control of the
Company.
    
 
TRANSFER AGENT AND REGISTRAR
 
     The transfer agent and registrar for the Common Stock is ChaseMellon
Shareholder Services.

                        SHARES ELIGIBLE FOR FUTURE SALE
 
   
     Upon completion of this offering, the Company will have 4,969,128 shares of
Common Stock outstanding, assuming the issuance of 1,361,942 shares by the
Company hereby (5,246,628 shares if the Underwriters' over-allotment option is
exercised in full). Of the outstanding shares, 1,850,000 (2,127,500 if the
Underwriters' over-allotment option is exercised in full) will be freely
tradable without restriction or further registration under the Securities Act,
unless held by "affiliates" of the Company, as that term is defined in Rule 144
under the Securities Act.
    
 
   
     The remaining 3,119,128 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,
194,864 shares are not subject to lockup agreements and will be eligible for
sale following this offering in the public market as follows: 159,639 shares
will be eligible for sale immediately without restriction pursuant to Rule
144(k) and 8,558 shares will be eligible for sale 90 days after the date of this
offering under Rule 701 and in reliance on Rule 144 without having to comply
with certain restrictions of Rule 144 as described below. The Company, its
officers and directors, the Selling Shareholders and certain other shareholders
(representing 2,924,264 shares of restricted securities) have agreed pursuant to
lockup agreements that they will not sell, directly or indirectly, any Common
Stock without the prior consent of Piper Jaffray Inc. for a period of 180 days
after the closing of this offering. Upon the expiration of this 180-day period
(or earlier upon the consent of Piper Jaffray Inc.), 2,628,598 of these
restricted shares will become eligible for sale in the public market as follows:
2,442,358 shares will be eligible for immediate sale without restriction
pursuant to Rule 144(k) and 186,240 shares will be eligible for sale immediately
(or 90 days after the date of this offering with the earlier consent of Piper
Jaffray Inc.) under Rule 701 and in reliance on Rule 144 without having to
comply with certain restrictions of Rule 144 as described below.
    
 
   
     In general, under Rule 144, as currently in effect, a person who has owned
shares for at least two years would be entitled to sell, within any three-month
period, that number of shares that does not exceed the greater of (i) 1% of the
then-outstanding shares of Common Stock (approximately 49,691 shares immediately
after this offering) and (ii) the average weekly trading volume in the Common
Stock during the four calendar weeks preceding the date the notice of sale is
filed with the Commission, subject to certain other limitations and
restrictions. In addition, a person who is not deemed to have been an affiliate
of the Company at any time during the three months preceding a sale, and who has
beneficially owned the shares proposed to be sold for at least three years,
would be entitled to sell such shares under Rule 144(k) without regard to the
requirements described above. Under Rule 701, persons who purchase shares upon
exercise of options granted prior to the effective date of this offering are
entitled to sell such shares 90 days after the effective date of this offering
and in reliance on Rule 144 without having to comply with the holding period
requirements of Rule 144 and, in the case of nonaffiliates, without having to
comply with the public information, volume limitation, or notice provisions of
Rule 144.
    
 
   
     The holders of options to purchase 154,700 shares which have vested and are
not subject to lockup agreements could exercise their options and sell these
shares in compliance with Rule 701 beginning 90 days after the effective date of
this offering. The Company intends to file registration statements under the
Securities Act covering an aggregate of approximately 656,617 shares of Common
Stock reserved for issuance under the 1988 Plan, the 1995 Plan and the ESPP.
Such registration statements are expected to be filed 180 days after the date of
this Prospectus and will automatically become effective upon filing.
Accordingly, shares registered under such registration statements will be
available for sale in the open market, unless such shares are subject to vesting
restrictions with the Company or the contractual restrictions described above.
In addition, certain shareholders, representing approximately 2,555,637 shares
of Common Stock, have the right, subject to certain conditions, to include their
shares in future registration statements relating to SeaMED's securities and to
cause SeaMED to register certain shares of Common Stock owned by them.
    
 
     The Company can make no prediction as to the effect, if any, that sales of
shares of Common Stock or the availability of shares of Common Stock for sale
will have on the market price prevailing from time to time. Nevertheless, sales
of substantial amounts of Common Stock in the public markets or the perception
that such sales could occur could adversely affect the market price of the
Common Stock or the Company's ability to raise capital through an offering of
its equity securities.

</TABLE>
 
     Subject to the terms and conditions of the Purchase Agreement, the
Underwriters have agreed to purchase all of the Common Stock being sold pursuant
to the Purchase Agreement, if any is purchased (excluding shares covered by the
over-allotment option granted therein). In the event of a default by any
Underwriter, the Purchase Agreement provides that, in certain circumstances,
purchase commitments of the nondefaulting Underwriters may be increased or the
Purchase Agreement may be terminated.
 
     The Representatives have advised the Company and the Selling Shareholders
that the Underwriters propose to offer the shares of Common Stock directly to
the public initially at the public offering price set forth on the cover page of
this Prospectus and to certain dealers at such price less a concession of not
more than $          per share. Additionally, the Underwriters may allow, and
such dealers may reallow, a concession not in excess of $          per share to
certain other dealers. After the initial public offering, the public offering
price and other selling terms may be changed by the Underwriters.
 
     The Company has granted to the Underwriters an option, exercisable by the
Representatives within 30 days after the date of the Purchase Agreement, to
purchase up to an additional 277,500 shares of Common Stock at the same price
per share to be paid by the Underwriters for the other shares offered hereby. If
the Underwriters purchase any of such additional shares pursuant to this option,
each Underwriter will be committed to purchase such additional shares in
approximately the same proportion as set forth in the table above. The
Underwriters may exercise the option only for the purpose of covering
over-allotments, if any, made in connection with the distribution of the Common
Stock offered hereby.
 
     The Representatives have informed the Company and the Selling Shareholders
that neither they, nor any other member of the National Association of
Securities Dealers, Inc. participating in the distribution of this offering,
will make sales of the Common Stock offered hereby to accounts over which they
exercise discretionary authority without the prior specific written approval of
the customer.
 
     As of the date of this Prospectus, Needham Capital SBIC, L.P., an affiliate
of Needham & Company, Inc., beneficially owned shares of Class D Preferred Stock
convertible into 133,333 shares of Common Stock. These shares were purchased on
January 3, 1995 in reliance upon the exemption from registration set forth in
Section 4(2) of the Securities Act relating to sales by an issuer not involving
any public offering. Needham & Company, Inc. and certain of its affiliates may
be deemed to own shares convertible into 35,555 shares of Common Stock held by
Needham Capital SBIC, L.P. as a result of ownership interests in such
partnership.

     The offering of the shares is made for delivery when, as and if accepted by
the Underwriters and subject to prior sale and to withdrawal, cancellation or
modification of this offering without notice. The Underwriters reserve the right
to reject an order for the purchase of shares in whole or in part.
 
   
     The officers and directors of the Company, the Selling Shareholders and
certain other shareholders designated by the Representatives, who will
beneficially own in the aggregate 2,924,264 shares of Common Stock after this
offering, have agreed that they will not, directly or indirectly, sell, contract
to sell, make any short sale, pledge or otherwise dispose of any shares of
Common Stock, options to acquire shares of Common Stock or securities
exchangeable for or convertible into shares of Common Stock that such persons
may own, of record or beneficially, or have the right to acquire, for a period
of 180 days after the closing of this offering, without the prior written
consent of Piper Jaffray Inc. The Company has agreed that it will not, directly
or indirectly, without the prior written consent of Piper Jaffray Inc., issue,
offer, sell, contract to sell, pledge or otherwise dispose of any shares of
Common Stock, options or warrants to acquire shares of Common Stock or
securities exchangeable for or convertible into Common Stock during the 180-day
period following the closing of this offering, except that the Company may issue
shares upon the exercise of options granted prior to the date hereof, and may
grant additional options under the Company's existing stock option and purchase
plans.
    
 
     Prior to this offering, there has been no public market for the Common
Stock. The initial public offering price for the Common Stock will be determined
by negotiations between the Company and the Representatives. Among the factors
considered in determining the initial public offering price will be prevailing
market and economic conditions, the Company's revenues and earnings, estimates
of the Company's business potential and prospects, the present state of the
Company's business operations, an assessment of the Company's management and the
consideration of the above factors in relation to the market valuations of
companies in related businesses. The initial public offering price for the
Common Stock should not be considered as an indication of the actual value of
the Common Stock offered hereby. In addition, there can be no assurance that the
Common Stock may be resold at a price equal to or greater than the initial
public offering price. See "Risk Factors -- Absence of Prior Market; Potential
Volatility of Common Stock Price."
 
     The Company and the Selling Shareholders have agreed to indemnify the
Underwriters and their controlling persons against certain liabilities,
including liabilities under the Securities Act, and to contribute to payments
the Underwriters may be required to make in respect thereof.
 
                                 LEGAL MATTERS
 
     The validity of the shares of Common Stock offered hereby will be passed
upon for the Company and the Selling Shareholders by Preston Gates & Ellis,
Seattle, Washington. William H. Gates, Sr., a partner of the firm and a director
of the Company, beneficially owns 28,000 shares of Common Stock. Mark R. Beatty,
a partner of the firm, serves as Secretary of the Company. Certain legal matters
will be passed upon for the Underwriters by Perkins Coie, Seattle, Washington.

               REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS
 
Board of Directors
SeaMED Corporation
 
     We have audited the accompanying balance sheets of SeaMED Corporation as of
June 30, 1995 and 1996, and the related statements of income, shareholders'
equity, and cash flows for each of the three years in the period ended June 30,
1996. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatements. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of SeaMED Corporation as of
June 30, 1995 and 1996, and the results of its operations and its cash flows for
each of the three years in the period ended June 30, 1996, in conformity with
generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
 
   
               (INFORMATION AS OF SEPTEMBER 30, 1996 AND FOR THE
    
   
            QUARTERS ENDED SEPTEMBER 30, 1995 AND 1996 IS UNAUDITED)
    
 
1. ACCOUNTING POLICIES
 
     Description of Business
 
     SeaMED Corporation (the "Company") is a leading manufacturer of advanced
medical instruments for medical technology companies. The Company manufactures
durable electronic medical instruments for its customers, often as part of
systems that also include single-use components. To assist its customers in
developing and commercializing their instruments for manufacture by the Company,
the Company provides a wide range of engineering services and regulatory
expertise.
 
     Change in Accounting Period
 
     During fiscal year 1995, the Company changed its fiscal year-end from June
30 to a 52/53-week fiscal year that ends on the Thursday nearest to June 30. For
convenience of presentation, all fiscal periods in these financial statements
are shown as ending on a calendar month-end.
 
   
     Unaudited Interim Financial Information
    
 
   
     The financial information as of September 30, 1996 and for the quarters
ended September 30, 1995 and 1996 is unaudited, but includes all adjustments
(consisting only of normal recurring adjustments) that the Company considers
necessary for a fair presentation of the financial position at such dates and
the operations and cash flows for the periods then ended. Operating results for
the quarter ended September 30, 1996 are not necessarily indicative of results
that may be expected for the entire year.
    
 
     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.
 
     Credit Policies
 
     The Company extends credit to various customers which are primarily in the
medical device industry. Receivables generally are due within 30 days and the
Company generally does not require collateral. The Company maintains reserves
for potential credit losses.
 
     Short-Term Investments
 
     Short-term investments consist of certificates of deposit with a maturity
date of less than one year from June 30, 1995.
 
     Inventories
 
     Inventories are stated at the lower of cost (first-in, first-out) or
market.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
 
   
               (INFORMATION AS OF SEPTEMBER 30, 1996 AND FOR THE
    
   
            QUARTERS ENDED SEPTEMBER 30, 1995 AND 1996 IS UNAUDITED)
    
 
     Depreciation
 
     The Company provides for depreciation of furniture, fixtures, equipment and
manufacturing molds over their estimated useful lives of three to eight years
using the straight-line method.
 
     Revenue Recognition
 
   
     The Company recognizes revenues from contracts to perform engineering
design and product development as costs are incurred for cost-plus contracts, or
based on the percentage-of-completion method for fixed-price contracts. When
estimates indicate a probable loss on a contract, the full amount of such loss
is accrued at that time. The Company generally recognizes revenue from
manufacturing services when the related products are shipped.
    
 
     Warranty Costs
 
     Warranty reserves are recorded based on historical experience and estimates
of current warranty activity.
 
     Income Taxes
 
     The Company provides for income taxes based on the liability method which
requires the 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 Compensation
 
   
     The Company has elected to follow Accounting Principles Board Opinion No.
25, "Accounting for Stock Issued to Employees," and related interpretations in
accounting for its employee stock options. Generally, stock compensation, if
any, is measured as the difference between the exercise price of a stock option
and the fair market value of the Company's stock at the date of grant, which is
then amortized over the related vesting period.
    
 
     Net Income Per Share and Pro Forma Net Income Per Share
 
   
     Except as noted below, historical primary net income per share is based on
the weighted average number of common and common equivalent shares outstanding
during each period. Common equivalent shares include outstanding Class B and C
convertible redeemable preferred stock and outstanding stock options and an
outstanding warrant. Common equivalent shares are not included in the per share
calculations where the effect of their inclusion would be antidilutive, except
that, in accordance with Securities and Exchange Commission requirements, common
and common equivalent shares issued during the 12-month period prior to the
filing of a proposed initial public offering have been included in the
calculation as if they were outstanding for all periods (using the treasury
stock method and an assumed initial public offering price). In addition, net
income is adjusted for the accretion of cumulative preferred stock dividends to
determine earnings applicable to common stock.
    
 
     Fully diluted net income per share has been computed as described above and
also gives effect to the dilutive effect of the conversion of outstanding Class
A and D convertible redeemable preferred stock net of the effect of the related
cumulative dividends.

6. CONVERTIBLE REDEEMABLE PREFERRED STOCK
 
   
     On January 3, 1995, the Company sold 1,465,000 shares of Class D
convertible redeemable preferred stock at $1.00 per share. These shares are
convertible into common stock at the ratio of 3.75 shares of preferred stock for
each share of common stock. In connection with the Class D preferred stock
offering, the Company also issued a warrant to purchase 39,066 shares of common
stock, with an exercise price of $4.70 per share. The warrant expires December
21, 1999.
    
 
   
     If the initial public offering referred to in Note 13 is consummated, all
convertible redeemable preferred stock will convert into 2,934,029 shares of
common stock and the cumulative dividends on Class A and D preferred stock
($1,664,024 and $1,729,786 at June 30, 1996 and September 30, 1996,
respectively) will be declared and paid with a portion of the net proceeds of
the offering. The unaudited pro forma balance sheet and unaudited pro forma
statement of shareholders' equity reflect the assumed conversion of all
preferred stock and the accrual of cumulative preferred stock dividends as of
September 30, 1996.
    
 
   
     At June 30, 1996 and September 30, 1996, the Company's convertible

     In the event the offering referred to in Note 13 is not consummated, the
following terms and conditions will continue to apply. Convertible redeemable
preferred stock is convertible into common stock, at the option of the holder,
at various rates, subject to antidilution provisions and any accrued but unpaid
dividends. Unissued shares of common stock are reserved for issuance in the
event of full conversion of all convertible redeemable preferred stock. Subject
to certain conditions, convertible redeemable preferred stock also has mandatory
conversion requirements in the event of a qualified initial public offering of
the Company's common stock.
    
 
     Each share of convertible redeemable preferred stock has voting rights
equivalent to the number of shares of common stock issuable, if converted. Class

of liquidation value.
 
 7. SHAREHOLDERS' EQUITY
 
     Reverse Stock Split
 
   
     Subsequent to year-end, in July 1996, the Company's shareholders approved a
1-for-5 stock split of the common stock, which resulted in an adjustment to the
preferred stock conversion ratio. All share and per share data in the
accompanying financial statements have been retroactively restated to reflect
the reverse stock split.
    
 
   
     Stock Option and Incentive Plans
    
 
   
     The Company has two stock option and incentive plans (collectively, the
"Plans"), the SeaMED Corporation 1988 Stock Option Plan and the SeaMED
Corporation 1995 Employee Stock Option and Incentive Plan. Under the terms of
the Plans, with respect to incentive stock options and options awarded to
nonemployee directors, the option price may not be less than fair market value
of the common stock at the date of grant. Generally, options granted under the
Plans become exercisable at the rate of 50% after two years, 75% after three
years, and 100% after four years from the date of grant. Certain options granted
under the 1988 plan, however, become exercisable ratably over seven years from
the date of grant. Unexercised options expire on the date set forth in the
optionee's option agreement (generally 10 years), subject to earlier termination
upon the happening of certain events set forth in the 1988 plan (with respect to
options granted under the 1988 plan) and each optionee's option agreement. Stock
options exercised, granted, and canceled during fiscal years 1994, 1995, and
1996 and the quarter ended September 30, 1996, are as follows:

</TABLE>
 
     The decrease in the valuation allowance of $443,000 in fiscal year 1994 and
$251,000 in fiscal year 1995 is primarily attributable to the utilization of net
operating loss carryforwards and tax credit carryforwards and related changes in
the estimate of the amount of deferred tax assets to be realizable.
 
   
     Taxes of $15,000, $28,000, $330,000, $150,000 and $600,000 were paid in the
fiscal years ended June 30, 1994, 1995, and 1996, and the quarters ended
September 30, 1995 and 1996, respectively.

12. RELATED-PARTY TRANSACTIONS
 
   
     In January 1995, the Company issued 1,465,000 shares of Class D preferred
stock, which are convertible into an aggregate of 390,666 shares of common stock
at an as-converted price of $3.75 per share. Two directors of the Company
purchased 25,000 and 40,000 shares, respectively, of Class D preferred stock,
which shares are convertible into 6,667 and 10,667 shares of common stock,
respectively. The Company sold such securities pursuant to a preferred stock
purchase agreement on substantially similar terms as were sold to nonaffiliated
purchasers. The terms of the Class D preferred stock provides that all such
shares shall be converted into Common Stock upon the consummation of the
offering referred to in Note 13.
    
 
   
     On October 11, 1995, the Company's Chief Executive Officer and President
received a $75,000 loan from the Company, the proceeds of which he used to
purchase 30,000 shares of common stock. The loan is evidenced by an unsecured
promissory note that bears interest at the floating minimum statutory rate set
by the Internal Revenue Service from time to time. This officer may prepay
principal and interest at any time without penalty; unpaid principal and
interest are due on October 11, 2000. As of June 30, 1996, aggregate principal
and accrued interest on this loan was approximately $78,000.
    
 
     A director of the Company is also a partner in the law firm Preston Gates &
Ellis, the Company's counsel.
 
     A director of the Company serves as President and Chief Executive Officer
and a director of one of the Company's customers. The Company has provided
engineering and manufacturing services for this customer. The Company recognized
revenues with respect to such services of approximately $1.0 million in fiscal
year 1995 and $355,000 in fiscal year 1996. The Company recognized no revenues
in fiscal year 1994 with respect to such services.
 
13. SUBSEQUENT EVENTS
 
   
     Registration Statement and Increase in Authorized Capital Stock
    
 
   
     In July 1996, the Company's Board of Directors delegated authority to a
newly formed Executive Committee to authorize filing a Registration Statement
with the Securities and Exchange Commission to permit the Company to sell shares
of its common stock to the public. If the offering is consummated under the
terms presently anticipated, all of the Company's preferred stock will convert
into 2,934,029 shares of common stock and cumulative dividends will be paid from
a portion of the net proceeds of the offering. Also, in July 1996, the Company's
Board of Directors approved an increase in the total number of authorized shares
to 24,050,500, of which 10,000,000 are for common stock and 14,050,500 are for
preferred stock. The respective amounts have been retroactively adjusted on the
accompanying balance sheet and these notes to financial statements.

ITEM 14.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
     Sections 23B.08.500 through 23B.08.600 of the Washington Business Act
authorize Washington corporations to indemnify their officers, directors,
employees and agents under certain circumstances against certain expenses that
they may incur in such capacities, including liabilities under the Securities
Act, provided they acted in good faith and in a manner reasonably calculated to
be in or not opposed to the best interests of the corporation. The Registrant's
Articles of Incorporation (Exhibit 3.1 hereto) and Bylaws (Exhibit 3.2 hereto)
require indemnification of the Registrant's officers and directors to the
fullest extent permitted by Washington law. The Registrant also maintains
directors' and officers' liability insurance on its directors and officers.
 
     The Registrant's Bylaws and Articles of Incorporation provide that the
Registrant shall, to the fullest extent permitted by the Washington Business
Act, indemnify all directors and officers of the Registrant. In addition, the
Registrant's Articles of Incorporation contain a provision eliminating the
personal liability of directors to the Registrant or its shareholders for
monetary damages arising out of a breach of fiduciary duty. Section 23B.08.320
of the Washington Business Act authorizes a corporation to limit or eliminate
such directors' liability for breaches of fiduciary duty, but does not eliminate
the personal liability of any director for (i) acts or omissions of a director
finally adjudged to be intentional misconduct or a knowing violation of law,
(ii) conduct finally adjudged to be in violation of Section 23B.08.310 of the
Washington Business Act (which section relates to unlawful distributions), or
(iii) any transaction with respect to which it is finally adjudged that a
director personally received a benefit in money, property or services to which
the director was not legally entitled.
 
     The above discussion of the Washington Business Act and the Registrant's
Bylaws and Articles of Incorporation is not intended to be exhaustive and is
qualified in its entirety by reference to such statute, the Bylaws and the
Articles of Incorporation, respectively.
 
     The Registrant will enter into indemnification agreements with each of its
directors and executive officers.

ITEM 17.  UNDERTAKINGS.
 
     The undersigned registrant hereby undertakes to provide to the Underwriters
at the closing specified in the Purchase Agreement, certificates in such
denominations and registered in such names as required by the Underwriters to
permit prompt delivery to each purchaser.
 
     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the registrant of expenses incurred
or paid by a director, officer or controlling person of the registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the adjudication of such
issue.

     The undersigned registrant hereby undertakes:
 
          (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 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.

1.       REGISTRATION STATEMENT AND PROSPECTUS

         A registration statement on Form S-1 (File No. 333-13455) with respect
to the Securities, including a preliminary form of prospectus, has been
prepared by the Company in conformity with the requirements of the Securities
Act of 1933, as amended (the "Act"), and the rules and regulations (the "Rules
and Regulations") of the Securities and Exchange Commission (the "Commission")
thereunder and has been filed with the Commission; one or more amendments to
such registration statement have also been so prepared and have been, or will
be, so filed; and, if the Company has elected to rely upon Rule 462(b) of the
Rules and Regulations to increase the size of the offering registered under the
Act, the Company will prepare and file with the Commission a registration
statement with respect to such increase pursuant to Rule 462(b) of the Rules
and Regulations.  Copies of such registration statement(s) and amendments and
each related preliminary prospectus have been delivered to you.  If the Company
has elected not to rely upon Rule 430A of the Rules and Regulations, the
Company has prepared and will promptly file an amendment to the registration
statement and an amended prospectus (including a term sheet meeting the
requirements of Rule 434 of the Rules and Regulations).  If the Company has
elected to rely upon Rule 430A of the Rules and Regulations, it will prepare
and file a prospectus (or a term sheet meeting the requirements of Rule 434 of
the Rules and Regulations) pursuant to Rule 424(b) of the Rules and Regulations
that discloses the information previously omitted from the prospectus in
reliance upon Rule 430A of the Rules and Regulations.  Such registration
statement as amended at the time it is or was declared effective by the
Commission, and, in the event of any amendment thereto after the effective date
and prior to the First Closing Date (as hereinafter defined), such registration
statement as so amended (but only from and after the effectiveness of such
amendment), including a registration statement (if any) filed pursuant to Rule
462(b) of the Rules and Regulations increasing the size of the offering
registered under the Act and information (if any) deemed to be part of the
registration statement at the time of effectiveness pursuant to Rules 430A(b)
of the Rules and Regulations and 434(d) of the Rules and Regulations, is
hereinafter called the "Registration Statement."  The prospectus included in
the Registration Statement at the time it is or was declared effective by the
Commission is hereinafter called the "Prospectus," except that if any
prospectus (including any term sheet meeting the requirements of Rule 434 of
the Rules and Regulations provided by the Company for use with a prospectus
subject to completion within the meaning of Rule 434 of the Rules and
Regulations in order to meet the requirements of Section 10(a) of the Act)
filed by the Company with the Commission pursuant to Rule 424(b) (and Rule 434,
if applicable) of the Rules and Regulations or any other such prospectus
provided to the Underwriters by the Company for use in connection with the
offering of the Securities (whether or not required to be filed by the Company
with the Commission pursuant to Rule 424(b) of the Rules and Regulations)
differs from the prospectus on file at the time the Registration




                                      -2-
<PAGE>   3
Statement is or was declared effective by the Commission, the term "Prospectus"
shall refer to such differing prospectus (including any term sheet within the
meaning of Rule 434 of the Rules and Regulations) from and after the time such
prospectus is filed with the Commission or transmitted to the Commission for
filing pursuant to such Rule 424(b) (and Rule 434, if applicable) of the Rules
and Regulations or from and after the time it is first provided to the
Underwriters by the Company for such use.  The term "Preliminary Prospectus" as
used herein means any preliminary prospectus included in the Registration
Statement prior to the time it becomes or became effective under the Act and
any prospectus subject to completion as described in Rule 430A or 434 of the
Rules and Regulations.

2.       REPRESENTATIONS AND WARRANTIES OF THE COMPANY AND THE SELLING
         SHAREHOLDERS

         (a)     The Company represents and warrants to, and agrees with, the
several Underwriters as follows:

                  (i)     No order preventing or suspending the use of any
Preliminary Prospectus has been issued by the Commission and each Preliminary
Prospectus, at the time of filing thereof, did not contain an untrue statement
of a material fact or omit to state a material fact required to be stated
therein or necessary to make the statements therein, in the light of the
circumstances under which they were made, not misleading; except that the
foregoing shall not apply to statements in or omissions from any Preliminary
Prospectus in reliance upon, and in conformity with, written information
furnished to the Company by you, or by any Underwriter through you,
specifically for use in the preparation thereof.

                 (ii)     As of the time the Registration Statement (or any
post-effective amendment thereto, including a registration statement (if any)
filed pursuant to Rule 462(b) of the Rules and Regulations increasing the size
of the offering registered under the Act) is or was declared effective by the
Commission, upon the filing or first delivery to the Underwriters of the
Prospectus (or any supplement to the Prospectus (including any term sheet
meeting the requirements of Rule 434 of the Rules and Regulations)) and at the
First Closing Date and Second Closing Date (as hereinafter defined), (A) the
Registration Statement and Prospectus (in each case, as so amended and/or
supplemented) conformed or will conform in all material respects to the
requirements of the Act and the Rules and Regulations, (B) the Registration
Statement (as so amended) did not or will not include an untrue statement of a
material fact or omit to state a material fact required to be stated therein or
necessary to make the statements therein, in light of the circumstances in 
which they are or were made, not misleading, and (C) the Prospectus (as so
supplemented) did not or will not include an untrue statement of a material fact
or omit to state a material fact required to be stated therein or necessary to 



                                      -3-
<PAGE>   4
make the statements therein, in light of the circumstances in which they are or
were made, not misleading; except that the foregoing shall not apply to
statements in or omissions from any such document in reliance upon, and in
conformity with, written information furnished to the Company by you, or by any
Underwriter through you, specifically for use in the preparation thereof.  If
the Registration Statement has been declared effective by the Commission, no
stop order suspending the effectiveness of the Registration Statement has been
issued, and no proceeding for that purpose has been initiated or, to the
Company's knowledge, threatened by the Commission.

                (iii)     The financial statements of the Company, together
with the notes thereto, set forth in the Registration Statement and Prospectus
comply in all material respects with the requirements of the Act and the Rules
and Regulations and fairly present the financial condition of the Company as of
the dates indicated and the results of operations and changes in cash flows for
the periods therein specified in conformity with generally accepted accounting
principles consistently applied throughout the periods involved (except as
otherwise stated therein); and the supporting schedules included in the
Registration Statement present fairly the information required to be stated
therein.  No other financial statements or schedules are required to be
included in the Registration Statement or Prospectus.  Ernst & Young LLP, which
has expressed its opinion with respect to the financial statements and
schedules filed as a part of the Registration Statement and included in the
Registration Statement and Prospectus, is an independent public accountant as
required by the Act and the Rules and Regulations.

                 (iv)     The Company has been duly organized and is validly
existing as a corporation in good standing under the laws of the state of
Washington.  The Company has full corporate power and authority to own its
properties and conduct its business as currently being carried on and as
described in the Registration Statement and Prospectus, and is duly qualified
to do business as a foreign corporation in good standing in each jurisdiction
in which it owns or leases real property or in which the conduct of its
business makes such qualification necessary and in which the failure to so
qualify would have a material adverse effect upon its business, condition
(financial or otherwise) or properties, taken as a whole.

                  (v)     Except as contemplated in the Prospectus, subsequent
to the respective dates as of which information is given in the Registration
Statement and the Prospectus, the Company has not incurred any material
liabilities or obligations, direct or contingent, or entered into any material
transactions, or declared or paid any dividends or made any distributions of
any kind with respect to its capital stock; and there has not been any change
in the capital stock (other than a change in the number of outstanding shares
of Common Stock due to the issuance of shares upon the exercise of outstanding
options or warrants), or any material change in the short-term or long-term
debt, or any issuance of options, warrants, convertible securities or other
rights to purchase the capital stock, of





                                      -4-
<PAGE>   5
the Company, or any material adverse change, or any development involving a
prospective material adverse change, in the general affairs, condition
(financial or otherwise), business, key personnel, property, prospects, net
worth or results of operations of the Company, taken as a whole.

                 (vi)     Except as set forth in the Prospectus, there is not
pending or, to the knowledge of the Company, threatened or contemplated, any
action, suit or proceeding to which the Company is a party before or by any
court or governmental agency, authority or body, or any arbitrator, which might
reasonably be expected to result in any material adverse change in the
condition (financial or otherwise), business, prospects, net worth or results
of operations of the Company, taken as a whole.

                (vii)     There are no contracts or documents of the Company
that are required to be filed as exhibits to the Registration Statement by the
Act or by the Rules and Regulations that have not been so filed.

               (viii)     This Agreement has been duly authorized, executed and
delivered by the Company, and constitutes a valid, legal and binding obligation
of the Company, enforceable in accordance with its terms, except as rights to
indemnity hereunder may be limited by federal or state securities laws and
except as such enforceability may be limited by bankruptcy, insolvency,
reorganization or similar laws affecting the rights of creditors generally and
subject to general principles of equity.  The execution, delivery and
performance of this Agreement and the consummation of the transactions herein
contemplated will not result in a breach or violation of any of the terms and
provisions of, or constitute a default under, any statute, any agreement or
instrument to which the Company is a party or by which it is bound or to which
any of its property is subject, the Company's charter or by-laws, or any order,
rule, regulation or decree of any court or governmental agency or body having
jurisdiction over the Company or any of its properties; no consent, approval,
authorization or order of, or filing with, any court or governmental agency or
body is required for the execution, delivery and performance of this Agreement
or for the consummation of the transactions contemplated hereby, including the
issuance or sale of the Securities by the Company, except such as may be
required under the Act or state securities or blue sky laws; and the Company
has full power and authority to enter into this Agreement and to authorize,
issue and sell the Securities as contemplated by this Agreement.

                 (ix)     All of the issued and outstanding shares of capital
stock of the Company, including the outstanding shares of Common Stock, are
duly authorized and validly issued, fully paid and nonassessable, have been
issued in compliance with all federal and state securities laws (other than
such noncompliance as would not have a material adverse effect on the condition
(financial or otherwise), prospects, net worth or results of operations of the
Company), were not issued in violation of or subject to any





                                      -5-
<PAGE>   6
preemptive rights or other rights to subscribe for or purchase securities, and
the holders thereof are not subject to personal liability by reason of being
such holders; the Securities which may be sold hereunder by the Company have
been duly authorized and, when issued, delivered and paid for in accordance
with the terms hereof, will have been validly issued and will be fully paid and
nonassessable, and the holders thereof will not be subject to personal
liability by reason of being such holders; and the capital stock of the
Company, including the Common Stock, conforms to the description thereof in the
Registration Statement and Prospectus.  Except as otherwise stated in the
Registration Statement and Prospectus, there are no preemptive rights or other
rights to subscribe for or to purchase, or any restriction upon the voting or
transfer of, any shares of Common Stock pursuant to the Company's charter,
by-laws or any agreement or other instrument to which the Company is a party or
by which the Company is bound.  Except to the extent of the sales by the
Selling Shareholders contemplated by this Agreement, neither the filing of the
Registration Statement nor the offering or sale of the Securities as
contemplated by this Agreement gives rise to any rights which have not been
waived for or relating to the registration of any shares of Common Stock or
other securities of the Company.  Except as described in the Registration
Statement and the Prospectus, there are no options, warrants, agreements,
contracts or other rights in existence to purchase or acquire from the Company
any shares of the capital stock of the Company.  The Company has an authorized
and outstanding capitalization as set forth in the Registration Statement and
the Prospectus.

                  (x)     The Company holds, and is operating in compliance in
all material respects with, all franchises, grants, authorizations, licenses,
permits, easements, consents, certificates and orders of any governmental or
self-regulatory body required for the conduct of its business, except where the
failure, individually or in the aggregate, to obtain or noncompliance with such
would not have a material adverse effect on the condition (financial or
otherwise), prospects, net worth or results of operations of the Company;  all
such franchises, grants, authorizations, licenses, permits, easements,
consents, certifications and orders are valid and in full force and effect; and
the Company is in compliance in all respects with all applicable federal,
state, local and foreign laws, regulations, orders and decrees, which
noncompliance would have a material adverse effect on the condition (financial
or otherwise), prospects, net worth or results of operations of the Company.

                 (xi)     The Company has good and marketable title to all
property described in the Registration Statement and Prospectus as being owned
by it, in each case free and clear of all liens, claims, security interests or
other encumbrances, except such as are described in the Registration Statement
and the Prospectus or such as do not materially affect the value of such
property, are not material in amount and do not interfere in any material
respect with the use of the property or the conduct of the business of the
Company; the property held under lease by the Company is held by it under
valid,





                                      -6-
<PAGE>   7

per share.  The obligation of each Underwriter to each of the Company and the
Selling Shareholders shall be to purchase from each of the Company and the
Selling Shareholders that number of Firm Shares (to be adjusted by the
Representatives to avoid fractional shares) which represents the same
proportion of the number of Firm Shares to be sold by each of the Company and
the Selling Shareholders pursuant to this Agreement as the number of Firm
Shares set forth opposite the name of such Underwriter in Schedule II hereto
represents to the total number of Firm Shares to be purchased by all
Underwriters pursuant to this Agreement.  In making this Agreement, each
Underwriter is contracting severally and not jointly; except as provided in
paragraph (c) of this Section 3 and in





                                      -11-
<PAGE>   12
Section 8 hereof, the agreement of each Underwriter is to purchase only the
respective number of Firm Shares specified in Schedule II.

         The Firm Shares will be delivered by the Company and the Custodian to
you for the accounts of the several Underwriters against payment of the
purchase price therefor by wire transfer of same-day funds payable to the order
of the Company and the Custodian, as appropriate, at the offices of Piper
Jaffray Inc., Piper Jaffray Tower, 222 South Ninth Street, Minneapolis,
Minnesota, or such other location as may be mutually acceptable, at 9:00 a.m.
Central time on the third (or if the Securities are priced, as contemplated by
Rule 15c6-1(c) under the Exchange Act, after 4:30 p.m. Eastern time, the
fourth) full business day following the date hereof, or at such other time and
date as you and the Company determine pursuant to Rule 15c6-1(a) under the
Exchange Act, such time and date of delivery being herein referred to as the
"First Closing Date."  If the Representatives so elect, delivery of the Firm
Shares may be made by credit through full fast transfer to the accounts at The
Depository Trust Company designated by the Representatives.  Certificates
representing the Firm Shares, in definitive form and in such denominations and
registered in such names as you may request upon at least two business days'
prior notice to the Company and the Custodian, will be made available for
checking and packaging not later than 10:30 a.m., Central time, on the business
day next preceding the First Closing Date at the offices of Piper Jaffray Inc.,
Piper Jaffray Tower, 222 South Ninth Street, Minneapolis, Minnesota, or such
other location as may be mutually acceptable.

         (b)     On the basis of the representations, warranties and agreements
herein contained, but subject to the terms and conditions herein set forth, the
Company, with respect to the Option Shares hereby grants to the several
Underwriters an option to purchase all or any portion of the Option Shares at
the same purchase price as the Firm Shares, for use solely in covering any
over-allotments made by the Underwriters in the sale and distribution of the
Firm Shares.  The option granted hereunder may be exercised at any time (but
not more than once) within 30 days after the effective date of this Agreement
upon notice (confirmed in writing) by the Representatives to the Company
setting forth the aggregate number of Option Shares as to which the several
Underwriters are exercising the option, the names and denominations in which
the certificates for the Option Shares are to be registered and the date and
time, as determined by you, when the Option Shares are to be delivered, such
time and date being herein referred to as the "Second Closing" and "Second
Closing Date," respectively; provided, however, that the Second Closing Date
shall not be earlier than the First Closing Date nor earlier than the second
business day after the date on which the option shall have been exercised.  The
First Closing Date and the Second Closing Date are sometimes herein
individually called the "Closing Date" and collectively called the "Closing
Dates."  The number of Option Shares to be purchased by each Underwriter shall
be the same percentage of the total number of Option Shares to be purchased by
the several Underwriters as the number of





                                      -12-
<PAGE>   13
Firm Shares to be purchased by such Underwriter is of the total number of Firm
Shares to be purchased by the several Underwriters, as adjusted by the
Representatives in such manner as the Representatives deem advisable to avoid
fractional shares.  No Option Shares shall be sold and delivered unless the
Firm Shares previously have been, or simultaneously are, sold and delivered.

         The Option Shares will be delivered by the Custodian and the Company,
as appropriate, to you for the accounts of the several Underwriters against
payment of the purchase price therefor by wire transfer of same-day funds
payable to the order of the Custodian or the Company, as appropriate, at the
offices of Piper Jaffray Inc., Piper Jaffray Tower, 222 South Ninth Street,
Minneapolis, Minnesota, or such other location as may be mutually acceptable at
9:00 a.m., Central time, on the Second Closing Date.  If the Representatives so
elect, delivery of the Option Shares may be made by credit through full fast
transfer to the accounts at The Depository Trust Company designated by the
Representatives.  Certificates representing the Option Shares in definitive
form and in such denominations and registered in such names as you have set
forth in your notice of option exercise will be made available for checking and
packaging not later than 10:30 a.m., Central time, on the business day next
preceding the Second Closing Date at the offices of Piper Jaffray Inc., Piper
Jaffray Tower, 222 South Ninth Street, Minneapolis, Minnesota, or such other
location as may be mutually acceptable.

         (c)     It is understood that you, individually and not as
Representatives of the several Underwriters, may (but shall not be obligated
to) make payment to the Company or the Selling Shareholders, on behalf of any
Underwriter for the Securities to be purchased by such Underwriter.  Any such
payment by you shall not relieve any such Underwriter of any of its obligations
hereunder.  Nothing herein contained shall constitute any of the Underwriters
an unincorporated association or partner with the Company or any Selling
Shareholder.

4.       COVENANTS

         (a)     The Company covenants and agrees with the several Underwriters

provisions of, Rule 462(b) of the Rules and Regulations; the Company will

with the distribution of the Securities by the Underwriters; and the Company

any such purpose; and the Company will promptly use its best efforts to prevent
the issuance of any stop order or to obtain its withdrawal if such a stop order
should be issued.

                (iii)     Within the time during which a prospectus (including

relating to the Securities is required to be delivered under the Act, the
Company will comply as far as it is able with all requirements imposed upon it
by the Act, as now and hereafter amended, and by the Rules and Regulations, as
from time to time in force, so far as necessary to permit the continuance of
sales of or dealings in the Securities as contemplated by the provisions hereof
and the Prospectus.  If during such period any event occurs as a result of
which the Prospectus would include an untrue statement of a material fact or
omit to state a material fact necessary to make the statements therein, in the
light of the circumstances then existing, not misleading, or if during such
period it is necessary to amend the Registration Statement or supplement the
Prospectus to comply with the Act, the Company will promptly notify you and

or indirectly, any action designed to or which might reasonably be expected to
cause or result in, or which has constituted, the stabilization or manipulation
of the price of any security of the Company to facilitate the sale or resale of
the Securities, and has not sold any Common Stock which are required to be
disclosed in response to Item 701 of Regulation S-K under the Act which have
not been so disclosed in the Registration Statement.

               (xiii)     The Company will inform the Florida Department of
Banking and Finance at any time prior to the consummation of the distribution
of the Securities by the Underwriters if it commences engaging in business with
the government of Cuba or with any person or affiliate located in Cuba.  Such
information will be provided within 90 days after the commencement thereof or
after a change occurs with respect to previously reported information.

                (xiv)     During a period of one hundred eighty (180) days
after the commencement of the public offering of the Securities by the
Underwriters, the Company will not file a registration statement for the
purpose of registering shares of the Company's equity securities issuable under
any option plan or other employee benefit plan.

         (b)     Each Selling Shareholder, severally and not jointly, covenants
and agrees with the several Underwriters as follows:

                  (i)     Except as otherwise agreed to by the Company and the
Selling Shareholder, such Selling Shareholder will pay all taxes, if any, on
the transfer and sale, respectively, of the Securities being sold by such
Selling Shareholder, the fees of such Selling Shareholder's counsel and such
Selling Shareholder's proportionate share (based upon the number of Securities
being offered by such Selling Shareholder pursuant to the Registration
Statement) of all costs and expenses (except for legal and accounting expenses
and fees of the registrar and transfer agent) incurred by the Company pursuant
to the provisions of Section 4(a)(viii) of this Agreement; provided, however,
that each Selling Shareholder severally agrees to reimburse the Company for any
reimbursement made by the Company to the Underwriters pursuant to Section
4(a)(viii) hereof to the extent such reimbursement resulted from the failure or
refusal on the part of such Selling Shareholder to comply under the terms or
fulfill any of the conditions of this Agreement.

                 (ii)     If this Agreement shall be terminated by the
Underwriters because of any failure, refusal or inability on the part of such
Selling Shareholder to perform any





                                      -17-
<PAGE>   18
agreement on such Selling Shareholder's part to be performed, or because any
other condition of the Underwriters' obligations hereunder required to be
fulfilled by such Selling Shareholder is not fulfilled, such Selling
Shareholder agrees to reimburse the several Underwriters for all out-of-pocket
disbursements (including fees and disbursements of counsel for the
Underwriters) incurred by the Underwriters in connection with their
investigation, preparing to market and marketing the Securities or in
contemplation of performing their obligations hereunder.  The Selling
Shareholder shall not in any event be liable to any of the Underwriters for
loss of anticipated profits from the transactions covered by this Agreement.

                (iii)     The Securities to be sold by such Selling
Shareholder, represented by the certificates on deposit with the Custodian
pursuant to the Custody Agreement of such Selling Shareholder, are subject to
the interest of the several Underwriters and the other Selling Shareholders;
the arrangements made for such custody are, except as specifically provided in
the Custody Agreement, irrevocable; and the obligations of such Selling
Shareholder hereunder shall not be terminated, except as provided in this
Agreement or in the Custody Agreement, by any act of such Selling Shareholder,
by operation of law, whether by the liquidation, dissolution or merger of such
Selling Shareholder, by the death of such Selling Shareholder, or by the
occurrence of any other event.  If any Selling Shareholder should liquidate,
dissolve or be a party to a merger or if any other such event should occur
before the delivery of the Securities hereunder, certificates for the
Securities deposited with the Custodian shall be delivered by the Custodian in
accordance with the terms and conditions of this Agreement as if such
liquidation, dissolution, merger or other event had not occurred, whether or
not the Custodian shall have received notice thereof.

                 (iv)     Such Selling Shareholder will not, without your prior
written consent, offer for sale, sell, contract to sell, grant any option for
the sale of or otherwise dispose of any Common Stock or any securities
convertible into or exchangeable for, or any options or rights to purchase or
acquire, Common Stock, except to the Underwriters pursuant to this Agreement,
for a period of 180 days after the commencement of the public offering of the
Securities by the Underwriters.

                  (v)     Such Selling Shareholder has not taken and will not
take, directly or indirectly, any action designed to or which might reasonably
be expected to cause or result in stabilization or manipulation of the price of
any security of the Company to facilitate the sale or resale of the Securities,
and has not effected any sales of Common Stock which, if effected by the
Company, would be required to be disclosed in response to Item 701 of
Regulation S-K.

                 (vi)     Such Selling Shareholder shall immediately notify you
if any event occurs, or of any change in information relating to such Selling
Shareholder or the Company or any new information relating to the Company or
relating to any matter stated





                                      -18-
<PAGE>   19
in the Prospectus or any supplement thereto (including any term sheet within
the meaning of Rule 434 of the Rules and Regulations), which results in the
Prospectus (as supplemented) including an untrue statement of a material fact
or omitting to state a material fact necessary to make the statements therein,
in light of the circumstances under which they were made, not misleading.

5.       CONDITIONS OF UNDERWRITERS' OBLIGATIONS

         The obligations of the several Underwriters hereunder are subject to

Selling Shareholders contained herein, to the performance by the Company and
the Selling Shareholders of their respective obligations hereunder and to the
following additional conditions:

         (a)     The Registration Statement shall have become effective not
later than 5:00 p.m., Central time, on the date of this Agreement, or such

Registration Statement or the Prospectus, or any amendment thereof or
supplement thereto (including any term sheet within the meaning of Rule 434 of
the Rules and Regulations), contains an untrue statement of fact which, in your
reasonable opinion, is material, or omits to state a fact which, in your
opinion, is material and is required to be stated therein or necessary to make
the statements therein not misleading.

         (c)     Except as contemplated in the Prospectus, subsequent to the
respective dates as of which information is given in the Registration Statement

                                      -19-

Company, or any material adverse change or any development involving a
prospective material adverse change (whether or not arising in the ordinary
course of business), in the general affairs, condition (financial or
otherwise), business, key personnel, property, prospects, net worth or results
of operations of the Company, taken as a whole, that, in your judgment, makes
it impractical or inadvisable to offer or deliver the Securities on the terms
and in the manner contemplated in the Prospectus.

as Representatives of the several Underwriters, the opinion of Preston Gates &

in the Prospectus, as of a date not more than five days prior to the date of
such letter), the conclusions and findings of said firm with respect to the
financial information and other matters covered by its letter delivered to you

as Representatives of the Underwriters, a certificate, dated such Closing Date
and addressed to you, signed by the chief executive officer and by the chief
financial officer of the Company, to the effect that:

                  (i)     The representations and warranties of the Company in
this Agreement are true and correct, in all material respects, as if made at
and as of such Closing Date, and the Company has complied with all the
agreements and satisfied all the conditions on its part to be performed or
satisfied at or prior to such Closing Date;

and

                (iii)     The signers of said certificate have carefully
examined the Registration Statement and the Prospectus, and any amendments
thereof or supplements thereto (including any term sheet within the meaning of
Rule 434 of the Rules and Regulations), and (A) such documents contain all
statements and information required to be included therein, the Registration
Statement, or any amendment thereof, does not contain any untrue statement of a
material fact or omit to state any material fact required to be stated therein
or necessary to make the statements therein, in light of the circumstances in
which they were made, not misleading, and the Prospectus, as amended or
supplemented, does not include any untrue statement of a material fact or omit
to state a material fact necessary to make the statements therein, in light of
the circumstances under which they were made, not misleading, (B) since the
effective date of the Registration Statement, there has occurred no event
required to be set forth in an amended or supplemented prospectus which has not
been so set forth, (C) subsequent to the respective dates as of which
information is given in the Registration Statement and the Prospectus, the
Company has not incurred any material liabilities or obligations, direct or
contingent, or entered into any material transactions, not in the ordinary
course of business, or declared or paid any dividends or made any distributions
of any kind with respect to its capital stock, except for those dividends on
the Company's Class A Preferred Stock and Class D Preferred Stock to be paid at

"Use of Proceeds" and except as disclosed in the Prospectus, there has not been
any change in the capital stock (other than a change in the number of
outstanding shares of Common Stock due to the issuance of shares upon the
exercise of outstanding options or warrants), or any material change in the
short-term or long-term debt, or any issuance of options, warrants, convertible
securities or other rights to purchase the capital stock, of the Company, or
any material adverse change or any development involving a prospective material
adverse change (whether or not arising





                                      -21-
<PAGE>   22
in the ordinary course of business), in the general affairs, condition
(financial or otherwise), business, key personnel, property, prospects, net
worth or results of operations of the Company, taken as a whole, and (D) except
as stated in the Registration Statement and the Prospectus, there is not
pending, or, to the knowledge of the Company, threatened or contemplated, any
action, suit or proceeding to which the Company is a party before or by any
court or governmental agency, authority or body, or any arbitrator, which might
result in any material adverse change in the condition (financial or
otherwise), business, prospects or results of operations of the Company, taken
as a whole.

         (h)     On each Closing Date, there shall have been furnished to you,
as Representatives of the several Underwriters, a certificate or certificates,
dated such Closing Date and addressed to you, signed by each of the Selling

The Company will furnish you with such conformed copies of such opinions,
certificates, letters and other documents as you shall reasonably request.

6.       INDEMNIFICATION AND CONTRIBUTION

         (a)     The Company and each Selling Shareholder, jointly and
severally, agree to indemnify and hold harmless each Underwriter against any
losses, claims, damages or liabilities, joint or several, to which such
Underwriter may become subject, under the Act or otherwise (including in
settlement of any litigation if such settlement is effected with the written
consent of the Company and/or such Selling Shareholders, as the case may be),
insofar as such losses, claims, damages or liabilities (or actions in respect
thereof) arise out of or are based upon an untrue statement or alleged untrue
statement of a material fact contained in the Registration Statement, including
the information deemed to be a part of the Registration Statement at the time
of effectiveness pursuant to Rules 430A and 434(d) of the Rules and
Regulations, if applicable, any Preliminary





                                      -22-
<PAGE>   23
Prospectus, the Prospectus, or any amendment or supplement thereto (including
any term sheet within the meaning of Rule 434 of the Rules and Regulations), or
arise out of or are based upon the omission or alleged omission to state
therein a material fact required to be stated therein or necessary to make the
statements therein not misleading, and will reimburse each Underwriter for any
legal or other expenses reasonably incurred by it in connection with
investigating or defending against such loss, claim, damage, liability or
action; provided, however, that neither the Company nor any Selling Shareholder
shall be liable in any such case to the extent that any such loss, claim,
damage, liability or action arises out of or is based upon an untrue statement
or alleged untrue statement or omission or alleged omission made in the
Registration Statement, any Preliminary Prospectus, the Prospectus, or any such
amendment or supplement, in reliance upon and in conformity with written
information furnished to the Company by you, or by any Underwriter through you,
specifically for use in the preparation thereof; and further provided, however,
that in no event shall any Selling Shareholder be liable under the provisions
of this Section 6 for any amount in excess of the aggregate amount of proceeds
such Selling Shareholder received from the sale of the Securities pursuant to
this Agreement.

         In addition to their other obligations under this Section 6(a), the
Company and each Selling Shareholder, jointly and severally, agree that, as an
interim measure during the pendency of any claim, action, investigation,
inquiry or other proceeding arising out of or based upon any statement or
omission, or any alleged statement or omission, described in this Section 6(a),
they will reimburse each Underwriter on a monthly basis for all reasonable
legal fees or other expenses incurred in connection with investigating or
defending any such claim, action, investigation, inquiry or other proceeding,
notwithstanding the absence of a judicial determination as to the propriety and
enforceability of the Company's and/or the Selling Shareholder's obligation to
reimburse the Underwriters for such expenses and the possibility that such
payments might later be held to have been improper by a court of competent
jurisdiction.  To the extent that any such interim reimbursement payment is so
held to have been improper, the Underwriter that received such payment shall
promptly return it to the party or parties that made such payment, together
with interest, compounded daily, determined on the basis of the prime rate (or
other commercial lending rate for borrowers of the highest credit standing)
announced from time to time by The Chase Manhattan Bank, N.A. (the "Prime
Rate").  Any such interim reimbursement payments which are not made to an
Underwriter within 30 days of a request for reimbursement shall bear interest
at the Prime Rate from the date of such request.  This indemnity agreement
shall be in addition to any liabilities which the Company or the Selling
Shareholders may otherwise have.

         (b)     Each Underwriter will indemnify and hold harmless the Company
and each Selling Shareholder against any losses, claims, damages or liabilities
to which the Company and the Selling Shareholders may become subject, under the
Act or otherwise (including in settlement of any litigation, if such settlement
is effected with the written





                                      -23-
<PAGE>   24
consent of such Underwriter), insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based upon an
untrue statement or alleged untrue statement of a material fact contained in
the Registration Statement, any Preliminary Prospectus, the Prospectus, or any
amendment or supplement thereto (including any term sheet within the meaning of
Rule 434 of the Rules and Regulations), or arise out of or are based upon the
omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein not misleading, in
each case to the extent, but only to the extent, that such untrue statement or
alleged untrue statement or omission or alleged omission was made in the
Registration Statement, any Preliminary Prospectus, the Prospectus, or any such
amendment or supplement thereto, in reliance upon and in conformity with
written information furnished to the Company by you, or by such Underwriter
through you, specifically for use in the preparation thereof, and will
reimburse the Company and the Selling Shareholders for any legal or other
expenses reasonably incurred by the Company or any such Selling Shareholder in
connection with investigating or defending against any such loss, claim,
damage, liability or action.

         (c)     Promptly after receipt by an indemnified party under
subsection (a) or (b) above of notice of the commencement of any action, such
indemnified party shall, if a claim in respect thereof is to be made against
the indemnifying party under such subsection, notify the indemnifying party in
writing of the commencement thereof; but the omission so to notify the
indemnifying party shall not relieve the indemnifying party from any liability
that it may have to any indemnified party.  In case any such action shall be
brought against any indemnified party, and it shall notify the indemnifying
party of the commencement thereof, the indemnifying party shall be entitled to
participate in, and, to the extent that it shall wish, jointly with any other
indemnifying party similarly notified, to assume the defense thereof, with
counsel satisfactory to such indemnified party, and after notice from the
indemnifying party to such indemnified party of the indemnifying party's
election so to assume the defense thereof, the indemnifying party shall not be
liable to such indemnified party under such subsection for any legal or other
expenses subsequently incurred by such indemnified party in connection with the
defense thereof other than reasonable costs of investigation; provided,
however, that if, in the sole reasonable judgment of the Representatives, it is
advisable for the Underwriters to be represented as a group by separate
counsel, the Representatives shall have the right to employ a single counsel to
represent the Representatives and all Underwriters who may be subject to
liability arising from any claim in respect of which indemnity may be sought by
the Underwriters under subsection (a) of this Section 6, in which event the
reasonable fees and expenses of such separate counsel shall be borne by the
indemnifying party or parties and reimbursed to the Underwriters as incurred
(in accordance with the provisions of the second paragraph in subsection (a)
above).  An indemnifying party shall not be





                                      -24-
<PAGE>   25
obligated under any settlement agreement relating to any action under this
Section 6 to which it has not agreed in writing.

         (d)     If the indemnification provided for in this Section 6 is
unavailable or insufficient to hold harmless an indemnified party under
subsection (a) or (b) above, then each indemnifying party shall contribute to
the amount paid or payable by such indemnified party as a result of the losses,
claims, damages or liabilities referred to in subsection (a) or (b) above, (i)
in such proportion as is appropriate to reflect the relative benefits received
by the Company and the Selling Shareholders on the one hand and the
Underwriters on the other from the offering of the Securities or (ii) if the
allocation provided by clause (i) above is not permitted by applicable law, in
such proportion as is appropriate to reflect not only the relative benefits
referred to in clause (i) above but also the relative fault of the Company and
the Selling Shareholders on the one hand and the Underwriters on the other in
connection with the statements or omissions that resulted in such losses,
claims, damages or liabilities, as well as any other relevant equitable
considerations.  The relative benefits received by the Company and the Selling
Shareholders on the one hand and the Underwriters on the other shall be deemed
to be in the same proportion as the total net proceeds from the offering
(before deducting expenses) received by the Company and Selling Shareholders
bear to the total underwriting discounts and commissions received by the
Underwriters, in each case as set forth in the table on the cover page of the
Prospectus.  The relative fault shall be determined by reference to, among
other things, whether the untrue or alleged untrue statement of a material fact
or the omission or alleged omission to state a material fact relates to
information supplied by the Company, the Selling Shareholders or the
Underwriters and the parties' relevant intent, knowledge, access to information
and opportunity to correct or prevent such untrue statement or omission.  The
Company, the Selling Shareholders and the Underwriters agree that it would not
be just and equitable if contributions pursuant to this subsection (d) were to
be determined by pro rata allocation (even if the Underwriters were treated as
one entity for such purpose) or by any other method of allocation which does
not take account of the equitable considerations referred to in the first
sentence of this subsection (d).  The amount paid by an indemnified party as a
result of the losses, claims, damages or liabilities referred to in the first
sentence of this subsection (d) shall be deemed to include any legal or other
expenses reasonably incurred by such indemnified party in connection with
investigating or defending against any action or claim which is the subject of
this subsection (d).  Notwithstanding the provisions of this subsection (d),
(i) no Underwriter shall be required to contribute any amount in excess of the
amount by which the total price at which the Securities underwritten by it and
distributed to the public were offered to the public exceeds the amount of any
damages that such Underwriter has otherwise been required to pay by reason of
such untrue or alleged untrue statement or omission or alleged omission and
(ii) no Selling Shareholder shall be required to contribute any amount in
excess of the





                                      -25-
<PAGE>   26
aggregate amount of proceeds such Selling Shareholder received from the sale of
the Securities pursuant to this Agreement.  No person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Act) shall be
entitled to contribution from any person who was not guilty of such fraudulent
misrepresentation.  The Underwriters' obligations in this subsection (d) to
contribute are several in proportion to their respective underwriting
obligations and not joint.

         (e)     The obligations of the Company and the Selling Shareholders
under this Section 6 shall be in addition to any liability which the Company
and the Selling Shareholders may otherwise have and shall extend, upon the same
terms and conditions, to each person, if any, who controls any Underwriter
within the meaning of the Act; and the obligations of the Underwriters under
this Section 6 shall be in addition to any liability that the respective
Underwriters may otherwise have and shall extend, upon the same terms and
conditions, to each director of the Company (including any person who, with his
consent, is named in the Registration Statement as about to become a director
of the Company), to each officer of the Company who has signed the Registration
Statement and to each person, if any, who controls the Company or any Selling
Shareholder within the meaning of the Act.

7.       REPRESENTATIONS AND AGREEMENTS TO SURVIVE DELIVERY

         All representations, warranties, and agreements of the Company herein
or in certificates delivered pursuant hereto, and the agreements of the several
Underwriters, the Company and the Selling Shareholders contained in Section 6
hereof, shall remain operative and in full force and effect regardless of any
investigation made by or on behalf of any Underwriter or any controlling person
thereof, or the Company or any of its officers, directors, or controlling
persons, or any Selling Shareholders or any controlling person thereof, and
shall survive delivery of, and payment for, the Securities to and by the
Underwriters hereunder.

8.       SUBSTITUTION OF UNDERWRITERS

         (a)     If any Underwriter or Underwriters shall fail to take up and
pay for the amount of Firm Shares agreed by such Underwriter or Underwriters to
be purchased hereunder, upon tender of such Firm Shares in accordance with the
terms hereof, and the amount of Firm Shares not purchased does not aggregate
more than 10% of the total amount of Firm Shares set forth in Schedule II
hereto, the remaining Underwriters shall be obligated to take up and pay for
(in proportion to their respective underwriting obligations hereunder as set
forth in Schedule II hereto except as may otherwise be determined by you) the
Firm Shares that the withdrawing or defaulting Underwriters agreed but failed
to purchase.





                                      -26-
<PAGE>   27
         (b)     If any Underwriter or Underwriters shall fail to take up and
pay for the amount of Firm Shares agreed by such Underwriter or Underwriters to
be purchased hereunder, upon tender of such Firm Shares in accordance with the
terms hereof, and the amount of Firm Shares not purchased aggregates more than
10% of the total amount of Firm Shares set forth in Schedule II hereto, and
arrangements satisfactory to you for the purchase of such Firm Shares by other
persons are not made within 36 hours thereafter, this Agreement shall
terminate.  In the event of any such termination neither the Company nor any
Selling Shareholder shall be under any liability to any Underwriter (except to
the extent provided in Section 4(a)(viii), Section 4(b)(ii) and Section 6
hereof) nor shall any Underwriter (other than an Underwriter who shall have
failed, otherwise than for some reason permitted under this Agreement, to
purchase the amount of Firm Shares agreed by such Underwriter to be purchased
hereunder) be under any liability to the Company or the Selling Shareholders
(except to the extent provided in Section 6 hereof).

         If Firm Shares to which a default relates are to be purchased by the
non-defaulting Underwriters or by any other party or parties, the
non-defaulting Representatives or the Company shall have the right to postpone
the First Closing Date for not more than seven business days in order that the
necessary changes in the Registration Statement, Prospectus and any other
documents, as well as any other arrangements, may be effected.  As used herein,
the term "Underwriter" includes any person substituted for an Underwriter under
this Section 8.

9.       EFFECTIVE DATE OF THIS AGREEMENT AND TERMINATION

         (a)     This Agreement shall become effective at 10:00 a.m., Central
time, on the first full business day following the effective date of the
Registration Statement, or at such earlier time after the effective time of the
Registration Statement as you in your discretion shall first release the
Securities for sale to the public; provided, that if the Registration Statement
is effective at the time this Agreement is executed, this Agreement shall
become effective at such time as you in your discretion shall first release the
Securities for sale to the public.  For the purpose of this Section 9, the
Securities shall be deemed to have been released for sale to the public upon
release by you of the publication of a newspaper advertisement relating thereto
or upon release by you of telexes offering the Securities for sale to

hereinafter specified before the time this Agreement becomes effective, you, as
Representatives of the several Underwriters, or the Company may prevent this
Agreement from becoming effective without liability of any party to any other
party, except that the provisions of Section 4(a)(viii), Section 4(b)(ii) and

         (b)     You, as Representatives of the several Underwriters, shall
have the right to terminate this Agreement by giving notice as hereinafter
specified at any time at or prior to the First Closing Date, and the option
referred to in Section 3(b), if exercised, may be cancelled at any time prior
to the Second Closing Date, if (i) the Company shall have failed, refused or
been unable, at or prior to such Closing Date, to perform any agreement on its
part to be performed hereunder, (ii) any other condition of the Underwriters'
obligations hereunder is not fulfilled, (iii) trading on the New York Stock
Exchange, the American Stock Exchange or Nasdaq shall have been wholly

by order of the Commission or any other governmental authority having
jurisdiction, (v) a banking moratorium shall have been declared by federal, New
York or Washington authorities, or (vi) there has occurred any material adverse
change in the financial markets in the United States or an outbreak of major
hostilities (or an escalation thereof) in which the United States is involved,
a declaration of war by Congress, any other substantial national or
international calamity or any other event or occurrence of a similar character
since the execution of this Agreement that in your judgment, makes it
impractical or inadvisable to proceed with the completion of the sale of and
payment for the Securities.  Any such termination shall be without liability of
any party to any other party except that the provisions of Section 4(a)(viii),
Section 4(b)(ii) and Section 6 hereof shall at all times be effective.

         If one or more of the Selling Shareholders shall fail at the First
Closing Date to sell and deliver the number of Securities which such Selling
Shareholder or Selling Shareholders are obligated to sell hereunder, and the
remaining Selling Shareholders do not exercise the right hereby granted to
increase, pro rata or otherwise, the number of Securities to be sold by them
hereunder to the total number of Securities to be sold by all Selling
Shareholders as set forth in Schedule I hereto, then the Underwriters may at
your option, by notice from you to the Company and the non-defaulting Selling
Shareholders, either (a) terminate this Agreement without any liability on the
part of any non- defaulting party or (b) elect to purchase the Securities which
the Company and the non-defaulting Selling Shareholders have agreed to sell
hereunder.

         In the event of a default by any Selling Shareholder as referred to in

non-defaulting Selling Shareholders shall have the right to postpone the First
Closing Date for a period not exceeding seven days in order to effect any
required changes in the Registration Statement or Prospectus or in any other
documents or arrangements.

         If the Company shall fail at the First Closing Date to sell and
deliver the number of Securities which it is obligated to sell hereunder, then
this Agreement shall terminate without any liability on the part of any
non-defaulting party.

         No action taken pursuant to this Section 10 shall relieve the Company
or any Selling Shareholders so defaulting from liability, if any, in respect of
such default.

Re:     Registration Statement on Form S-1 of SeaMED Corporation (Commission
        File No. 333-13455)

Ladies and Gentlemen:

        We have acted as counsel to SeaMED Corporation (the "Company") in
connection with the filing of the above-referenced Registration Statement (the
"Registration Statement") relating to the registration of shares (the "Shares")
of Common Stock, no par value per share, of the Company.  In connection
therewith, we have reviewed the Company's Articles of Incorporation, Bylaws,
minutes of appropriate meetings, and such other matters we deemed appropriate.

        Based on that review, it is our opinion that the Shares will be, when
sold pursuant to the terms contemplated by the Registration Statement, validly
issued, fully paid and non-assessable under the Washington Business
Corporation Act.

        We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to all references to our firm included in or made a
part of the Registration Statement.

SECTION 2.    PRODUCT CHANGES; TOOLING

Buyer shall be the owner of all Documentation and all associated patent,
copyright, trade secret and other proprietary rights.

         2.2 TOOLING. Seller shall hold the Tooling for use in the manufacture,
assembly and testing of the Products. Buyer shall bear the cost of
manufacturing, preventative maintenance and normal wear repairing of all
Tooling. Buyer shall be the owner of all Tooling (and Seller shall place a
permanent marking on all Tooling showing Buyer's ownership and shall execute and
deliver any and all documents as Buyer may reasonably request to vest, evidence
or give public notice of Buyer's ownership). Seller shall deliver any and all
Tooling to Buyer promptly on request and in any event at the end of the Term in

         3.2 ORDERS; DELIVERY SCHEDULE. Each of Buyer's Orders for Products
shall be submitted to Seller substantially in the form of the purchase order
attached as Exhibit C or such other form as may be utilized by Buyer for
ordering Products under this Agreement. Each Order shall contain a description
of the Products ordered, specify the shipping destination (if any at that time),
specify the quantity of Products ordered and specify the dates on which each
ordered Product is to be made available to Buyer for acceptance testing with
respect to the first three month period covered by the Order schedule, along
with a forecast of when additional Product will be acceptance tested for the
remaining quarters covered by the Order. No less than ninety (90) days prior to
any such forecasted quarter, Buyer will supply Seller with a definitive schedule
for Product acceptance testing timing and quantities for such quarter. The
definitive quantity may vary from the forecasted quantity by plus or minus
thirty percent (30%). Time is of the essence in this Agreement. If one or more
Lots is not made available for delivery and acceptance testing in accordance
with the definitive schedule provided by Buyer ("Short Lot(s)"), and the
reason(s) for such delay are within the reasonable control of Seller, and Seller
fails to ensure that, within eight (8) weeks from the date of the first Short
Lot, the cumulative number of Products in Lots actually made available for
acceptance testing and delivery is again equal to the number required through
that date under the definitive schedule, Seller shall be in material breach of
this Agreement and Buyer may terminate this Agreement and all or part of any
outstanding Orders at any time thereafter. Upon such termination, Buyer shall
pay Seller an amount equal to Seller's Burdened Costs (as defined in Section
3.5.2 below) for raw materials which are purchased by Seller (or for which
Seller has then placed noncancelable purchase orders) specifically for the
manufacture of such Products and which are returned to Seller's suppliers, sold
or otherwise disposed of as directed by Buyer.

         3.3 PURCHASE PRICE. As full compensation for the Products and the
performance of Seller's obligations under this Agreement, Buyer shall pay Seller
the price for each Product as established in each Order. Buyer requested changes
to (a) the Documentation or (b) to ordering components for subassemblies
resulting in a quantity less than the total purchase quantity for such Products
under such Order, may cause an increase or decrease in underlying materials
costs, and therefore in the price of Products.* The parties will work together
to ensure that the mechanics and documentation of implementing price changes
occur in an efficient manner for both Buyer and Seller.

         3.4 PAYMENT. Seller shall issue its invoice for the price of a Product
upon Buyer's approval of the Product pursuant to paragraph 4.1. Buyer shall pay
Seller the amount due under each of Seller's invoices within thirty (30) days
after Buyer's receipt of the invoice. Seller shall promptly furnish Buyer with
such documentation and information as Buyer may reasonably request to verify the
amount due under any of Seller's invoices.*

confidential treatment under Rule 406 under the Securities Act of 1933, as

         3.5 CANCELLATION OF ORDERS.

                  3.5.1 Buyer may not cancel any Order as it applies to Products
scheduled for delivery within ninety (90) days after Buyer gives Seller notice
of the cancellation.

                  3.5.2 Buyer may cancel any Order as it applies to Products
scheduled for delivery more than ninety (90) days after Buyer gives Seller
notice of the cancellation; provided that, with respect to canceled Products
scheduled for delivery more than ninety (90) but less than three hundred sixty
five (365) days after Buyer gives Seller notice of the cancellation, Buyer shall
agree to pay Seller an amount equal to Seller's Burdened Costs (as defined
below) for raw materials which are purchased by Seller (or for which Seller has
then placed noncancelable purchase orders) specifically for the manufacture of
such Products and which are returned to Seller's suppliers, sold or otherwise
disposed of as directed by Buyer. Seller's "Burdened Costs" shall equal the
difference between the amount paid by Seller for such materials plus a handling
charge of * plus any bill back by Seller's suppliers for taking less than
amounts ordered with respect to Product Orders and the amount of any refund,
credit, allowance or compensation received by or on behalf of Seller for such
return, sale or other disposition. Seller shall furnish Buyer such receipts,
documents and other information as Buyer may reasonably request to verify
Seller's net Burdened Costs under this Agreement.

                  3.5.3 No cancellation shall relieve Buyer or Seller of any of
their respective obligations under this Agreement as to any Products not
canceled. If Buyer purports to cancel all or any part of any Order for Seller's
breach or default and it is determined that Seller was not in breach or default
that would permit such cancellation, then such cancellation shall be deemed to
have been a cancellation pursuant to this paragraph and the rights and
obligations of the parties shall be determined accordingly.

         3.6 SPARE PARTS. Seller will produce and sell and provide Buyer with
spare parts for the Products, which are configured and tested to the current
Product Specifications pursuant to Orders for such spare parts. * On Orders for
spares that provide for future delivery to Buyer, Seller will reasonably

portion of such spares in future Product manufacturing.

         4.1 ACCEPTANCE. Delivery of Products to Buyer shall be deemed to have
occurred upon acceptance of each lot of Products under any Order in accordance
with the following acceptance procedure. Seller shall notify Buyer when a
particular Product Lot is ready for acceptance testing. Buyer will promptly
inspect all or a portion of such Product Lot at Seller's Plant. Buyer may
conduct a statistical sampling of each such Lot of Products. If five percent

all at Seller's expense. However, if Seller will not be able to make, or does
not make, such required repairs within a reasonable time, Buyer may, at its
option, repair the noncomplying Products and charge Seller the reasonable cost
of the repair. Even if a Product Lot is accepted, Seller shall remain
responsible to correct nonconformities in any Product in such Lot under
paragraph 7.2.

         4.2 STORAGE OF COMPLETED PRODUCTS. Accepted Product lots shall be
stored in a clean and safe condition by Seller at Seller's Plant or any other
mutually acceptable location until Buyer requests shipment of individual
Products to Buyer's Plant. Seller shall retain all risk of loss with respect to
such stored Products until shipment. Once accepted pursuant to Section 4.1,
Buyer shall retain all right, title and interest in and to such Products. Seller
shall execute any and all documents reasonably required in order to protect
Buyer's ownership interest in all accepted and delivered Products. Seller shall
maintain general liability and any other insurance reasonably required to insure
against loss or damage of any nature to the Products and Tooling in amounts
equal to the full insurable value thereof. At Buyer's request, Seller shall
provide a certificate evidencing the above required insurance coverage.

otherwise identify each accepted Product for shipment to Buyer's Plant. Buyer
shall arrange and pay for all transportation, handling, transit insurance,
duties, governmental inspections and other requirements for delivery of the
Products in accordance with this Agreement. Shipments shall be F.O.B. Seller's
Plant.

         4.4 PACKAGING. Seller shall properly package the Purchased Products
according to Buyer's instructions for protection against damage or deterioration
that may result from shipment, handling, storage or other cause.

         4.5 SCHEDULE. Seller shall make the Products available for Buyer's
acceptance testing in accordance with the schedule set forth in the applicable
Order, as revised and updated as described in Section 3.2. However, Seller shall
not be liable for delays in delivery due to causes which are not reasonably
foreseeable, which are beyond Seller's control and which cannot be overcome by
the exercise of reasonable diligence; provided that Seller gives Buyer prompt
written notice of the circumstances giving rise to the delay, the anticipated
duration of the delay and the action being taken by Seller to overcome or
mitigate the delay. The specified delivery date shall be extended by the period
of any such delay.

SECTION 5.  INSPECTION

         5.1 SELLER'S PLANT. Seller's Plant and all Tooling shall be subject to
inspection by Buyer at any time during normal business hours upon twenty-four

access for such inspection.

         5.2 BY SELLER. Seller shall perform such detailed inspections and tests
of each Purchased Product as are necessary to ensure that such Product complies
with the requirements of this Agreement. Without limiting the generality of the
foregoing, Seller shall:

<PAGE>   6

                  (a) comply with the Inspection Procedures applicable to each
Purchased Product;

                  (b) inspect and test all materials and components to be
incorporated in any Purchased Product on receipt in order to assure material and
component quality; and

                  (c) keep and maintain complete and adequate records of all
inspections and tests performed on Purchased Products, and make such records
available to Buyer for examination, copying and audit.

         5.3 BY BUYER. All Products shall at all times be subject to inspection
and testing by Buyer upon 24 hours prior notice to Seller. Seller shall provide
Buyer with safe and sufficient access, equipment and facilities for any such
inspection or tests prior to delivery. No acceptance of any Products shall be
construed to result from any inspection, test or delay or failure to inspect or
test by Buyer prior to final inspection and test of such Products by Buyer.
Buyer shall be afforded a reasonable opportunity to inspect each Product for
damage at its specified destination. No inspection, test, delay or failure to
inspect or test, or failure to discover any defect or noncompliance by Buyer
shall relieve Seller of any of its obligations under this Agreement or impair
Buyer's right to reject defective or noncomplying Products or any other right or
remedy afforded to Buyer.

SECTION 6.    COMPLIANCE WITH LAWS AND STANDARDS

         6.1 GENERAL. Seller shall comply (and shall ensure that all Products
and Seller's subcontractors and suppliers of every tier comply) with all
applicable laws, ordinances, rules, regulations, orders, licenses, permits and
other requirements, now or hereafter in effect, of any governmental authority.
Seller shall furnish such documents as may be required to effect or evidence
such compliance. All laws, ordinances, rules, regulations and orders required to
be incorporated in agreements of this character are incorporated in this
Agreement by this reference.

         6.2 INDUSTRY STANDARDS. Seller shall produce all Products in accordance
with, and shall ensure that each Product complies with, the following
requirements as now or hereafter in effect:

assistance as Buyer may reasonably request in connection with the listing,
approval, registration or satisfaction of similar requirements of any trade
association or other organization, as the same may apply to the Product.

SECTION 7.    WARRANTY

         7.1 WARRANTY.  Seller warrants to Buyer that*

         7.2 CORRECTION OF NONCOMPLIANCE. If at any time during the Warranty
Period Buyer notifies Seller of any failure to comply with the warranty set
forth in paragraph 7.1, Seller shall promptly correct such noncompliance (e.g.,
by repair or replacement of the noncomplying Product) and remedy any damage to
the Product resulting from such failure.* If Buyer rejects any Products that do
not comply with the warranty set forth in paragraph 7.1, Seller shall have a
reasonable time to correct the noncompliance. If Seller fails to correct the
noncompliance within a reasonable time, Buyer may cancel the Order as it applies
to the noncomplying Products only without any cost, obligation or liability to
Buyer with respect to such noncomplying Products and without prejudice to any
other rights or remedies of Buyer with respect to such noncompliance (e.g., as
to damages or cover).

         7.3 SELLER'S FAILURE TO CORRECT NONCOMPLIANCE. If during the Warranty
Period Buyer requests Seller to correct any Product that does not comply with
the warranty set forth in paragraph 7.1 and Seller thereafter fails to correct
the noncompliance or otherwise comply with the requirements of paragraph 7.2, or
indicates its inability or unwillingness to comply, then Buyer may perform (or
cause performance of) the correction or otherwise achieve compliance by the most
expeditious means available to it (by contract or otherwise) and charge to or
otherwise recover (for example, by offset against the compensation otherwise
payable to Seller under this Agreement) from Seller all reasonable costs thereof
that are associated with the direct repair of the Product. Buyer's rights to
perform corrections, achieve compliance and recover the costs thereof from
Seller shall not be interpreted or construed as obligating Buyer to make any
correction or otherwise achieve compliance. Further, Seller's obligations
(including warranty) shall not be limited or reduced in any way because of any
corrections performed or caused to be performed by Buyer or Buyer's rights to
perform the same. However, Seller will have no obligation for damage to a
Product where such damage is caused by the efforts of Buyer or Buyer's
representative in correcting the noncompliance.

         7.4 RESPONSE TIME. Seller shall use its best efforts to perform such
warranty service by a qualified service technician within* from the time that
Seller receives the defective Product part, assuming material availability. If
the claim is not within Seller's warranty obligations under this paragraph 7,
Seller shall immediately notify Buyer and, at Buyer's option, shall either
return such Product part to Buyer or shall perform the required service under
paragraph 7.5 as directed by Buyer.

         7.5 SERVICE NOT COVERED BY WARRANTY. In the event that any Product
requires repair or other service that is not covered by Seller's warranty
obligations under this paragraph 7 (e.g., after expiration of the Warranty
Period), Seller shall provide such service *. Seller shall use its best efforts
to complete such repairs within *.

Company's directors or executive officers most favorably insured by such
policy.

                 (c)      The Company shall have no obligation to maintain D&O
Insurance if the Company, by majority vote of the Board of Directors,
determines in good faith that such insurance is not reasonably available, the
premium costs for such insurance are disproportionate to the amount of coverage
provided, or the coverage provided by such insurance is limited by





                                      -3-
<PAGE>   4
exclusions so as to provide an insufficient benefit; provided, however, that
such decision shall not adversely affect coverage of D&O Insurance for periods
prior to such decision without the unanimous vote of all directors.

         3.      Indemnification.  The Company shall indemnify Indemnified
Party up to the Covered Amount and shall advance or reimburse the Expenses
incurred by Indemnified Party in a Proceeding or in connection with any Covered
Acts, subject, in each case, to the further provisions of this Agreement.  This
Agreement is made pursuant to and to effectuate the indemnification provisions
set forth in Article 10 of the Articles of Incorporation and Article VII of the
Bylaws.  Notwithstanding any other provision of this Agreement, the Company
shall indemnify Indemnified Party to the extent Indemnified Party is
successful, on the merits or otherwise, in the defense of any Proceeding to
which Indemnified Party was a party because of being a director, officer,
employee, agent, fiduciary or consultant of the Company, against reasonable
Expenses incurred by Indemnified Party in connection with the Proceeding.

         4.      Excluded Coverage.  The Company shall have no obligation to
indemnify Indemnified Party for any Losses or Expenses which arise from an
Excluded Claim.

         5.      Indemnification Procedures.

                 (a)      Promptly after receipt by Indemnified Party of notice
of the commencement of or the threat of commencement of any Proceeding, if
indemnification or advancement or reimbursement of Expenses with respect
thereto may be sought from the Company under this Agreement, Indemnified Party
shall notify the Company of the commencement or the threat of commencement
thereof.

                 (b)      If, at the time of the receipt of such notice, the
Company has D&O Insurance in effect, the Company shall give prompt notice of
the commencement or the threat of commencement of such Proceeding to the
appropriate insurers in accordance with the procedures set forth in the
respective policies in favor of Indemnified Party.  The Company thereafter
shall take all necessary or desirable action to cause such insurers to pay, on
behalf of the Indemnified Party, all amounts (including, without limitation,
Losses and Expenses) payable as a result of such Proceeding in accordance with
the terms of such policies.

                 (c)      To the extent that, at the time of the commencement
of or the threat of commencement of such Proceeding, the Company does not have
applicable D&O Insurance, or if a Determination is made that any Loss, Fine or
Expense of the Indemnified Party arising out of such Proceeding will not be
payable under the D&O Insurance then in effect, the Company shall be obligated
to pay the Covered Amount with respect to any Proceeding and provide counsel
satisfactory to Indemnified Party, upon the delivery to Indemnified Party of
written notice of the Company's election to do so.  After delivery of such
notice, the Company will not be liable to Indemnified Party under this
Agreement for any legal or other Expenses subsequently incurred by the
Indemnified Party in connection with such defense other than the reasonable
Expenses of investigation of Indemnified Party; provided, however, that
Indemnified Party shall have the right to employ his or her own counsel in
connection with the defense of any such Proceeding, the fees





                                      -4-
<PAGE>   5
and expenses of such counsel incurred after delivery of notice from the Company
of its assumption of such defense to be at the Indemnified Party's sole
expense.  Notwithstanding the foregoing, if (i) the employment of counsel by
Indemnified Party has been previously authorized by the Company, (ii)
Indemnified Party shall have been advised by counsel that there may be a
conflict of interest between the Company and Indemnified Party in the conduct
of any such defense or (iii) the Company, in fact, shall not have employed
counsel to assume the defense of such Proceeding, in each such case, the fees
and expenses of such counsel retained by Indemnified Party shall be at the
expense of the Company.

                 (d)      All payments on account of the Company's
indemnification, advancement and reimbursement obligations under this Agreement
shall be made within sixty (60) days of Indemnified Party's written request
therefor unless a Determination is made that the claims giving rise to
Indemnified Party's request are Excluded Claims or otherwise not payable under
this Agreement; provided, however, that all payments on account of the
Company's obligations under Paragraph 5(c) of this Agreement prior to the
Adjudication of any Proceeding shall be made within twenty (20) days of
Indemnified Party's written request therefor and such obligation shall not be
subject to any such Determination but shall be subject to Paragraph 5(e) of
this Agreement.

                 (e)      Indemnified Party agrees that he or she will
reimburse the Company for all Losses and Expenses paid by the Company in
connection with any Proceeding against Indemnified Party in the event and only
to the extent that it is Adjudged that the Indemnified Party is not entitled to
be indemnified by the Company for such Losses or Expenses under this Agreement,
the Articles of Incorporation, the Bylaws or the Act.

         6.      Settlement.  The Company shall have no obligation to indemnify
Indemnified Party under this Agreement for any amounts paid in settlement of
any Proceeding effected without the Company's prior written consent.  The
Company shall not settle any claim in any manner which would impose any loss or
expense on Indemnified Party without Indemnified Party's prior written consent,
unless the Company provides a written undertaking to the Indemnified Party to
pay for such loss or expense on behalf of the Indemnified Party.  Neither the
Company nor Indemnified Party shall unreasonably withhold their consent to any
proposed settlement.

         7.      Rights Not Exclusive.  The rights provided hereunder shall be
in addition to any other rights to which Indemnified Party may be entitled
under the Articles of Incorporation, the Bylaws, the Act, any agreement or vote
of shareholders or directors or otherwise, both as to action in Indemnified
Party's official capacity and as to action in any other capacity, and such
rights shall continue after Indemnified Party ceases to serve the Company as a
director or officer.

         8.      Enforcement.

                 (a)      Indemnified Party's rights to indemnification or
reimbursement or advancement of Expenses hereunder shall be enforceable by
Indemnified Party notwithstanding any adverse Determination, other than a
Determination which has been made by Adjudication.  In any such action, if a
prior adverse Determination has been made, the burden of proving that
indemnification or reimbursement or advancement of Expenses is required under
this Agreement,





                                      -5-
<PAGE>   6
the Articles of Incorporation, the Bylaws or the Act shall be on the
Indemnified Party.  The Company shall have the burden of proving that
indemnification or reimbursement or advancement of Expenses is not required
under this Agreement if no prior adverse Determination shall have been made.

                 (b)      In the event that any action is instituted by
Indemnified Party under this Agreement, or to enforce or interpret any of the
terms of this Agreement, Indemnified Party shall be entitled to be paid all
court costs and expenses, including reasonable counsel fees, incurred by
Indemnified Party with respect to such action, unless the court determines that
each of the material assertions made by Indemnified Party as a basis for such
action were not made in good faith or were frivolous.

         9.      No Presumptions.  For purposes of this Agreement, the
termination of any Proceeding by judgment, order, settlement (whether with or
without court approval) or conviction, or upon a plea of nolo contendre, or its
equivalent, shall not create a presumption that the Indemnified Party did not
meet any particular standard of conduct or have any particular belief or that a
court has determined that indemnification or reimbursement or advancement of
Expenses by the Company is not permitted hereunder or by applicable law.  In
addition, neither the absence of a Determination as to whether Indemnified
Party has met any particular standard of conduct or had any particular belief
or the existence of a Determination that Indemnified Party has not met such
standard of conduct or did not have such belief, prior to the commencement of
legal proceedings by Indemnified Party to secure an Adjudication that
Indemnified Party should be indemnified or advanced or reimbursed Expenses
hereunder or under applicable law, shall be a defense to Indemnified Party's
claim or create a presumption that Indemnified Party has not met any particular
standard of conduct or did not have any particular belief.

         10.     Subrogation.  In the event of payment under this Agreement,
the Company shall be subrogated to the extent of such payment to all of the
rights of recovery of Indemnified Party, who shall execute all papers required
and shall do everything that may be necessary to secure such rights, including
the execution of such documents necessary to enable the Company to effectively
bring suit to enforce such rights.

         11.     No Duplication of Payments.  The Company shall not be liable
under this Agreement to make any payment in connection with any Proceeding
against Indemnified Party to the extent Indemnified Party has otherwise
actually received payment (under any D&O Insurance, the Articles of
Incorporation, the Bylaws, the Act or otherwise) of the amounts which may be
paid hereunder.

         12.     Severability.  In the event that any provision of this
Agreement is determined by a court of competent jurisdiction to require the
Company to do or to fail to do an act which is in violation of the Articles of
Incorporation, the Bylaws or the Act or other applicable law, such provision
shall be limited or modified in its application to the minimum extent necessary
to avoid such violation, and, as so limited or modified, such provision and the
remainder of this Agreement shall be enforceable in accordance with the
respective terms.





                                      -6-
<PAGE>   7
         13.     Choice of Law.  This Agreement shall be governed by, construed
and enforced in accordance with the laws of the State of Washington.

         14.     Successors and Assigns.  This Agreement shall be (a) binding
upon all successors and assigns of the Company (including any transferee of all
or substantially all of the Company's assets and any successor by merger or
otherwise by operation of law) and (b) binding on and inure to the benefit of
the heirs, personal representatives and estate of Indemnified Party.
Indemnified Party may not assign this Agreement or any of Indemnified Party's
rights hereunder without the prior written consent of the Company.

         15.     Amendment.  No amendment, modification, termination or
cancellation of this Agreement shall be effective unless made in a writing
signed by each of the parties hereto.

         IN WITNESS WHEREOF, the Company and Indemnified Party have executed
this Indemnification Agreement as of the date first above written.

                           PURCHASE AND SALE AGREEMENT

                                                                January 20, 1978



Cynergy, Inc.
13240 Northrup Way
Suite 20
Bellevue, WA 98005

Gentlemen:

      The undersigned, Pioneer Investors Corp., a New York corporation and a
federally-licensed Small Business Investment Company and Doan Resources
Corporation, a Michigan corporation and a federally-licensed Small Business
Investment Company (sometimes hereinafter referred to collectively as the
"Purchasers" and individually as a "Purchaser"), hereby agree, severally and not
jointly, with Cynergy, Inc., a Delaware corporation (the "Company"), as follows:

      1. Purchase of Notes. On the closing date defined in Section 7 below (the
"Closing Date"), subject to the terms and conditions hereof and in reliance upon
the representations, warranties and agreements contained herein, the Company
agrees to sell to each Purchaser, and each Purchaser agrees to purchase from the
Company, the Company's 7-year, 10% Subordinated Notes (the "Notes") in the
principal amount of $62,500, each, at a price equal to the principal amount of
the Notes. The Notes shall be dated the Closing Date, shall be issued in the
names of the respective Purchasers and shall be substantially in the form
attached hereto as Exhibit "A". The purchase price for the Notes shall be paid
by certified or official bank check payable to the order of the Company.

      The Company, at is election, may prepay the outstanding Notes at any time
as a whole, or from time to time in part, without payment of any premium or
prepayment charge, provided that interest accrued on such principal amount being
prepaid to the date of such prepayment shall be paid together with such
prepayment. In the case of any prepayment notice thereof shall be given not less
than 30 nor more than 60 days prior to the date fixed for such prepayment. In
the case of any prepayment of less than the entire unpaid principal amount of
all outstanding Notes, the amount to be prepaid shall be applied pro rata to all
outstanding Notes according to the respective unpaid principal amounts thereof.

      2. Purchase of Stock. On the Closing Date, subject to the terms and
conditions hereof and in reliance upon the representations, warranties and
agreements contained herein, the Company agrees to sell to each Purchaser, and
each Purchaser agrees to purchase from the Company, 142 shares (the "Sale
Stock") of the common stock of the Company, no par value (the "Common Stock"),
at a price of $440.14 per share, or an aggregate purchase price to each
<PAGE>   2
Purchaser of $62,500. The purchase price for the Sale Stock shall be paid by
certified or official bank check payable to the Company.

      3. Delivery of Warrants. On the Closing Date and contemporaneously with
the consummation of the purchase of the Notes and Sale Stock pursuant to
Sections 1 and 2 above, the Company will deliver to each Purchaser a Warrant
Certificate (the "Warrants") evidencing the right to purchase 141 shares (the
"Underlying Shares") of Common Stock. The Warrant Certificates shall be dated
the Closing Date, shall be issued in the names of the respective Purchasers and
shall be in substantially the form attached hereto as Exhibit B. The Warrants
are granted to the Purchasers in consideration of their purchase of the Notes
and Sale Stock and no additional payment shall be made or consideration given to
the Company, except as provided in Sections 1 and 2 above, in respect to the
delivery of the Warrants.

      4. Representations and Warranties by the Company. The Company represents
and warrants to the Purchasers, as follows:

            4.1   Organization, Standing and Qualification of the Company.

      The Company is a corporation duly organized, validly existing and in good
standing under the laws of the State of Delaware. The copies of the Company's
certificate of incorporation, by-laws, and all amendments to each to date, which
have been delivered to the Purchaser, are complete and correct as at the date of
this Agreement. The Company has the corporate power and authority to own its
property, to enter into, deliver and perform its obligations and undertakings
under this Agreement, to issue the Notes, Sale Stock and Warrants and to conduct
its business as now being conducted and as proposed to be conducted. The Company
is qualified to do business as a foreign corporation in the State of Washington,
which is the only jurisdiction in which the nature of the business conducted by
it or its ownership or leasing of property makes such qualification necessary.

            4.2 Subsidiaries. The Company has no subsidiaries and does not
control, directly or indirectly, any other corporation, association or business
organization.

            4.3 Capitalization. The Company's authorized capital stock consists
of 2,000 shares of Common Stock, of which 630 shares are issued and presently
outstanding. Attached hereto as Schedule 1 is a complete and correct list of all
the holders of Common Stock as of the date of this Agreement and the number of
shares held by each. All such outstanding shares are duly authorized, validly
issued, fully paid and nonassessable. The Sale Stock and Underlying Shares when
issued upon exercise of the Warrants will be validly authorized, issued and
outstanding, fully paid and non-assessable and the Sale Stock and Underlying
Shares have been duly authorized and reserved for issuance. The Company has not
granted or issued, or agreed to grant or issue, any option, warrant or other
commitment to issue or to acquire any shares of its capital stock or any
securities or obligations convertible into or exchangeable for, or giving any
person any right to acquire from the Company or sell to the Company, any shares
of its capital stock, except in accordance with the provisions of Sections 2 and
4.14 of this Agreement and under the terms of the Warrants. The Company holds no
shares of its capital stock in its treasury.


                                      -2-
<PAGE>   3
No holder of any security of the Company is entitled to pre-emptive or similar
rights as of the date of this Agreement. The Company will not place any
restrictions on the transfer of the Notes, Sale Stock, Warrants or Underlying
Shares, except to the extent set forth in Subsection 10.2 hereof. The Company
has not agreed to register any of its securities under the Securities Act of
1933, as amended (the "Act"), except as provided for in this Agreement and
except as set forth in Schedule 10 annexed hereto.

            4.4 Financial Information. The Company has delivered to each of the
Purchasers copies of the following financial statements:

                  (a) A balance sheet of the Company as at November 30, 1977,
and a statement of income, profit and loss for the period from December 16, 1976
and ended November 30, 1977, prepared by the chief financial officer of the
Company.

      Subject to normal year-end and audit adjustments, such financial
statements, including the related notes thereto, if any, are complete and
correct, have been prepared in accordance with generally accepted accounting
principles consistently followed throughout the periods involved and show all
liabilities, absolute or contingent, of the Company, and fairly present the
condition of the Company as at the dates thereof. There has been no change in
the accounting principles applied throughout the periods involved.

            4.5 Outstanding Debt. The Company has outstanding no indebtedness
for borrowed money, except as reflected on the Company's balance sheet as at
November 30, 1977 and except the Company is indebted to Pioneer Investors Corp.
in the amount of $20,000 pursuant to the demand loan made December 2, 1977, and
the Company is not a guarantor or otherwise contingently liable for any such
indebtedness. There exists no default under the provisions of any instrument
evidencing such indebtedness or of any agreement relating thereto.

            4.6 Absence of Undisclosed Liabilities. At November 30, 1977, the
Company had no material liabilities (fixed or contingent, including without
limitation any tax liabilities due or to become due) which are not fully
reflected or provided for on the balance sheet of the Company as at that date,
except obligations, all of which are listed on Schedule 2 hereto, to perform
after November 30, 1977, under commitments incurred in the ordinary course of
business, which in the aggregate do not involve the payment or expenditure by
the Company of more than $5,000. The Company does not know and has no reasonable
ground to know of any basis for the assertion against the Company, as at
November 30, 1977 (or as the date hereof) of any liability of any nature, direct
or indirect, contingent or otherwise, or in any amount not adequately reflected
or reserved against in said November 30, 1977, balance sheet, except as set
forth on Schedule 2 hereto.

            4.7   Absence of Certain Changes.  Except to the extent described
in Schedule 3 hereto, since November 30, 1977, there has not been:

otherwise), assets, liabilities, financial condition, business or prospects of
the Company from that shown on the Company's November 30, 1977 balance sheet;

                  (b) any damage, destruction or loss of any of the properties
or assets of the Company (whether or not covered by insurance) materially
adversely affecting the business or prospects of the Company;

                  (c) any declaration, setting-aside or payment or other
distribution in respect of any of the Company's capital stock, or any direct or
indirect redemption, purchase or other acquisition of any of such stock by the
Company; or

                  (d) any labor trouble, or any event or condition of any
character, materially adversely affecting the business or prospects of the
Company.

            4.8 Taxes. For all periods ended prior to November 30, 1977, the
Company has filed or will file within the time prescribed by law (including
extensions of time approved by the appropriate taxing authority) all tax returns
and reports required to be filed with the United States Internal Revenue
Service, with the States of Delaware and Washington and with all other
jurisdictions where such filing is required by law and has paid or made adequate
provision in said balance sheet dated November 30, 1977, for the payment of all
taxes, interest, penalties, assessments or deficiencies shown to be due or
claimed to be due on or in respect of such tax returns and reports. The Company
knows of (i) no other taxes which are required to be filed which have not been
so filed and (ii) no unpaid assessment for additional taxes for any fiscal
period or any basis thereof. The Company's federal income tax returns have not
been audited by the Internal Revenue Service.

            4.9 Contracts; Insurance. Except as set forth in Schedule 4 hereto,
the Company has no presently existing contract, obligation or commitment
(written or oral) of any nature extending beyond June 1, 1978, or involving

following:

                  (a) Employment, bonus or consulting agreements pension, profit
sharing, deferred compensation, stock bonus, retirement, stock option, stock
purchase, phantom stock or similar plans, including agreements evidencing rights
to purchase securities of the Company and agreements among shareholders and the
Company;

                  (b) Loan or other agreements, notes, indentures, or
instruments relating to or evidencing indebtedness for borrowed money, or
mortgaging, pledging or granting or creating a lien or security interest or
other encumbrance on any of the Company's property or any agreement or

commitments and of all other contracts and commitments to which it is a party,
and is not in default under any thereof.

      The Company maintains the types of insurance with the coverages set forth

financial condition against the risks involved in the business conducted by the
Company.

            4.10  Shareholders, Directors, and Officers; Compensation;

<PAGE>   6
      To the best of the Company's knowledge and belief, none of the officers,
directors or shareholders of the Company, or, their respective spouses or
relatives, owns directly or indirectly, individually or collectively, a material
interest in any entity which is a competitor, customer or supplier of (or has
any existing contractual relationship with) the Company.

            4.11 Litigation. There are no actions, suits, proceedings or claims
(whether or not purportedly on behalf of the Company) pending or, to the
Company's knowledge, threatened, against or relating to the Company, its
properties or business, nor does the Company know or have reasonable grounds to
know of any basis for any such action or any claim against the Company
(contingent or otherwise) or of any proceeding before or investigation by any
governmental or professional commission, administrative agency, or accrediting
organization relative to the Company, its properties or business, except as
disclosed on Schedule 6 hereto.

            4.12 Validity of this Agreement. The execution, delivery and
performance by the Company of this Agreement, the issue and sale of the Notes,
the Sale Stock and the Warrants and the issue of Underlying Shares on the
exercise of the Warrants have been duly authorized and approved by all necessary
corporate action. The Notes when issued will constitute the legal, valid
obligations of the Company, enforceable in accordance with their terms, except
for bankruptcy, moratorium and similar laws affecting the rights of creditors
generally. The execution and delivery of this Agreement and the issue of the
Notes, Sale Stock, Warrants and the Underlying Shares will not violate any

not be audited, but shall be certified as complete and correct, subject to
changes resulting from year-end adjustments, by the chief financial officer of
the Company.

            8.3 Certificates of Compliance. At each time of transmittal of the
statements referred to in Subsection 8.2, other than the interim monthly
statements referred to therein, the Company will deliver to the Purchasers a
certificate of the president and chief financial officer of the Company stating

reasonable times and as often as the Purchasers may reasonably request;
provided, that no person not an employee of the Purchaser shall be so permitted

the principal and interest on the Notes in accordance with the terms of this

profits, property or business of the Company or any subsidiary; provided,

validity thereof shall currently be contested in good faith by appropriate
proceedings and if the Company shall have set aside on its books adequate
reserves with respect thereto, and provided, further, that the Company will pay

securities issued with respect to the Sale Stock or the Underlying Shares by
reason of stock dividends, stock splits or combinations, recapitalizations,
reorganizations or other corporate action.

      "Holders" shall mean the Purchasers (in their capacity as holder of the

assigns who agree in writing with the Company to acquire and hold the Notes, the
Warrants or Shares, as the case may be, subject to all the restrictions hereof.


                                      -18-
<PAGE>   19
      "Commission" shall mean the Securities and Exchange Commission, or any
other Federal agency at the time administering the Securities Act.

      "Registration Expenses" and "Selling Expenses" shall mean the expenses so
described in Subsection 10.8 hereof.

      "Act" shall mean the Securities Act of 1933, or any successor Federal
statute, and the rules and regulations of the Commission thereunder, all as the
same shall be in effect at the time.

      "Transfer" shall mean any pledge, sale, assignment or other transfer of
the Notes, Warrants or any Shares or any interest therein whether or not such
transfer would constitute a "sale" as that term is defined in Section 2(3) of
the Act.

      "Underwriter" shall mean each person who is or may be deemed an
"underwriter", as that term is defined in Section 2(11) of the Act, in respect
of Shares which shall have been registered by the Company under the Act pursuant
to any of the provisions of this Section 10.

            10.2 Transfer Legends. The Transfer of the Notes, Shares and
Warrants will be restricted in accordance with the terms hereof. The Notes, each
Warrant Certificate and each certificate evidencing the Shares, including any
certificate issued to any transferee thereof, shall be stamped or otherwise
imprinted with legends, in the case of the Note, in the form set forth in
Exhibit A hereto, in the case of the Warrant Certificates in the form set forth
in Exhibit B hereto, and in the case of such share certificates, in
substantially the following form (unless otherwise permitted or unless such
Shares shall have been effectively registered and sold under the Act):

      "The Shares represented by this Certificate have not been registered under
the Securities Act of 1933 nor under any state securities law and may not be
pledged, sold, assigned or transferred unless (i) a registration statement with
respect thereto is effective under the Securities Act of 1933 and any applicable
State securities laws, or (ii) in the opinion of counsel to the Company or
Messrs. Reavis & McGrath such shares may be pledged, sold, assigned or
transferred without an effective registration statement under the Securities Act
of 1933 or applicable State securities laws."

      Upon request of a Holder of the Notes, the Warrants or any of the Shares,
the Company shall remove the foregoing legends from the Notes, Warrant
Certificate or the certificates evidencing such Shares, as the case may be, or
issue to such Holder a new Note, Warrant Certificate or certificates therefor
free of any transfer legend, if with such request, the Company shall have
received an opinion of Messrs. Reavis & McGrath or other counsel selected by the
Holder and reasonably satisfactory to the Company, to the effect that any
Transfer by said Holder of such Note, Warrant Certificate or the Shares, as the
case may be, will not violate the Act and applicable State securities laws, and
if counsel to the Company shall have approved the removal of such legend in
reliance on such opinion.

            10.3 Incidental Registration. If the Company shall at any time or
times hereafter determine to register under the Act any shares of its common
stock (other than a registration


                                      -19-
<PAGE>   20
statement on Form S-8 or other form which does not include substantially the
same information as would be required in a form for the general registration of
securities), it will promptly notify each Holder in writing in each case of such
determination and upon any Holder's written request given within thirty (30)
days after receipt by such Holder from the Company of such notification, the
Company will use its best efforts as soon as practicable thereafter to cause any
of the Shares specified by such Holder to be included in such registration
statement. Notwithstanding the foregoing, the Company shall not be required to
include Shares of such Holder therein if and to the extent the underwriter
managing the offering reasonably believes that such inclusion would adversely
affect the offering of the Shares to be covered by the proposed registration
statement, provided that any such exclusion shall be pro rata to all holders of
the Company's capital stock in proportion to the respective number of shares
that they shall have requested to be registered.

            10.4 Required Registration. If any time after one year after the
effective date of the first registration statement filed by the Company under
the Act, the Holders of at least 51% of the Shares shall notify the Company in
writing that such Holders intend to offer or cause to be offered for sale at
least 20% of the Shares and shall request the Company to cause such Shares to be
registered under the Act, the Company will use its best efforts as soon as
practicable thereafter to prepare and file a registration statement covering
such Shares (together with any other unregistered Shares requested by the
Holders thereof to be included in such registration within thirty (30) days
after receipt of a notice from the Company pursuant to Subsection 10.6 hereof).
Such right to require registration shall be in addition to the rights of the
Holders under Subsection 10.3 of this Agreement and shall be available to
Holders on not more than two occasions (exclusive of registration statements on
From S-16, as provided below); provided that each such registration statement
becomes and remains effective in accordance with the provisions hereof;
provided, further, that such Holders of at least 51% of the Shares shall have
the right to require the Company to file an unlimited number of registration
statements on Form S-16, if available, or its successors under the Act (in which
case the minimum percentage of Shares to be covered by any such registration
statement shall be 5%).

            10.5 Conditions of Obligations to Register Shares. Any distribution
of Shares registered pursuant to this Agreement shall, unless the Company shall
have given its prior written consent to other arrangements, be effected by means
of a firm or best efforts commitment underwriting managed by an investment
banking firm reasonably satisfactory to the Company. As a condition to the
Company's obligation hereunder to cause a registration statement to be filed or
Shares to be included in a registration statement, the Holder shall provide such
information and execute such documents as may reasonably be required in
connection with such registration. In addition, the Company shall not be
obligated to file a registration statement or to include Shares in a
registration statement hereunder if the Company shall have received opinions of
its counsel and of Messrs. Reavis & McGrath or other counsel to any Holder to
the effect that the proposed disposition of such Shares may be effected without
registration under the Act. No provision of this Section 10 shall be construed
as requiring the Company to register either the Notes or the Warrants under the
Act.

            10.6 Notification of Requests. If the Company shall at any time or
times determine, upon receipt of a request of any security holder or otherwise,
to register any of the


                                      -20-
<PAGE>   21
Shares or any other securities under the Act, the Company will, within fifteen
(15) days after such determination, give notice thereof to the Holders. The
Holders shall then be entitled to the right to registration to the extent
provided in Subsection 10.3 or 10.4 hereof, as the case may be.

            10.7 Registration Procedures. If and whenever the Company is
required by the provisions of this Section 10 to use its best efforts to include
any of the Shares in a registration statement filed under the Act, the Company
shall, as expeditiously as possible:

                  10.7.1 Prepare and file with the Commission a registration
statement with respect to such Shares and use its best efforts to cause such
registration statement to become and remain effective.

                  10.7.2 Prepare and file with the Commission such amendments
and supplements to such registration statement and the prospectus used in
connection therewith as may be necessary to keep such registration statement
effective for at least 90 days from the date of its effectiveness or (unless
otherwise required by the Act) until the Shares covered thereunder have been
sold, whichever is earlier.

                  10.7.3 Furnish to each Holder such number of copies of the
prospectus contained in such registration statement (including each preliminary
prospectus), in conformity with the requirements of the Act, and such other
documents as such Holder shall reasonably request in order to facilitate the
disposition of the Shares owned by such Holder.

                  10.7.4 Use its best efforts to register or qualify the Shares
covered by such registration statement under the blue sky laws of such
jurisdictions as each Holder shall reasonably request, and do any and all other
acts and things which may be necessary or advisable to enable such Holder to
consummate the disposition of the Shares owned by such Holder in such
jurisdictions during the period covered in Subsection 10.7.2; provided, however,
that in no event shall the Company be obligated (i) to qualify to do business in
any jurisdiction where it is not at the time so qualified; (ii) to take any
action which would subject it to the service of process of suits other than
those arising out of the offer or sale of the Shares covered by such
registration statement in any jurisdiction where it is not at the time so
subject; or (iii) to register or qualify under the securities laws of any such
jurisdiction if and to the extent the underwriter managing the offering
reasonably believes that such registration or qualification would adversely
affect the offering.

                  10.7.5 Notify each Holder of any shares covered by such
registration statement at any time when a prospectus relating thereto is
required to be delivered under the Act of the happening of any event as a result
of which the prospectus contained in such registration statement, as then in
effect, includes an untrue statement of a material fact or omits to state any
material fact required to be stated herein or necessary to make the statements
therein not misleading in the light of the circumstances then existing. Each
Holder agrees, upon receipt of such notice, forthwith to cease making offers and
sales of the Shares pursuant to such registration statement or deliveries of the
prospectus contained therein for any purpose and to return to the Company the
copies of such prospectus not theretofore delivered by such Holder.


                                      -21-
<PAGE>   22
                  10.7.6 At the request of any Holder, prepare and furnish to
such Holder a reasonable number of copies of any supplement to or amendment of
such prospectus that may be necessary so that, as thereafter delivered to the
Purchasers of such Shares, such prospectus shall not include an untrue statement
of a material fact or omit to state a material fact required to be stated
therein or necessary to make the statements therein not misleading in the light
of the circumstances then existing.

                  10.7.7 Provide an institutional transfer agent for the Shares
at least by the effective date of the first registration of any such Shares.

                  10.7.8 Promptly notify all selling Holders of any stop order
or similar proceeding initiated by state or federal regulatory bodies and use
its best efforts to take all necessary steps expeditiously to remove such stop
order or similar proceeding.

            10.8 Description of Expenses. All expenses incurred by the Company
in complying with any of the foregoing provisions of this Section 10, including
without limitation all filing fees, printing expenses, fees and disbursements of
counsel for the Company and accountants' fees and expenses, but excluding
underwriting discounts and selling commissions, incident to or required by any
such registration are herein called "Registration Expenses." All underwriting
discounts and selling commissions applicable to the sale of Shares hereunder and
all fees and disbursements of counsel to any Holder selling Shares hereunder are
herein called "Selling Expenses." If the Company is required by the provisions
of this Section 10 to use its best efforts to effect the registration of any of
the Shares under the Act, the Registration Expenses and Selling Expenses in
connection with such registration shall be borne by the Company, except that
each Holder shall pay the fees and disbursements of his own counsel and the
underwriting discounts and selling commissions applicable to his shares.

            10.9 Indemnification; Underwriting Agreements. In the event that the
Company registers under the Act any Shares held by a Holder:

                  10.9.1 The Company agrees to indemnify and hold harmless such
Holder, and each person, if any, who controls such Holder within the meaning of
the Act, against any losses, claims, damages or liabilities to which any such
Holder, controlling person or underwriter may become subject under the Act or
otherwise, insofar as such losses, claims, damages or liabilities (or actions in
respect thereof) shall arise out of or be based upon any untrue or allegedly
untrue statement of any material fact contained in the registration statement,
the related prospectus or any amendment or supplement thereto, or upon the
omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein not misleading, and
shall reimburse any legal or other expenses reasonably incurred by any such
Holder, controlling person or underwriter in connection with investigating or
defending against any such loss, claim, damage, liability or action; provided,
however, that the Company shall not be liable to any Holder, controlling person
or underwriter for any losses, claims, damages, liabilities or actions arising
out of or based upon any such untrue statement or omission


                                      -22-
<PAGE>   23
made in reliance upon and in conformity with written information furnished to
the Company by such Holder, controlling person or underwriter seeking
indemnification hereunder.

                  10.9.2 The obligations of the Company under Subsections 10.3
and 10.4 are subject to the conditions that each Holder whose shares are to be
included in any registration or qualification referred to in this Section 10 (i)
agrees, in writing, to indemnify and hold harmless the Company, each person, if
any, who controls the Company within the meaning of the Act and the officers and
directors of the Company, against any and all liability or expense arising out
of or based upon any untrue statement or alleged untrue statement of a material
fact in any related registration statement, prospectus, offering circular,
notification or other document or alleged omission of any material fact required
to be stated therein or necessary to make the statements therein not misleading,
but only with reference to statements or omissions made in reliance upon a
statement in writing furnished by or on behalf of such Holder for inclusion
therein and with reference to statements or omissions made in reliance upon an
omission or failure by such Holder to furnish any statement with respect to such
Holder required to be included therein, and (ii) if such registration or
qualification relates to an offering which is to be underwritten, enters into an
underwriting agreement in usual and standard form respecting such offering.

            10.10 Rule 144. The Purchasers recognize that the provisions of Rule
144 under the Securities Act are not presently applicable to securities of the
Company. After the effective date of the first registration statement filed by
the Company under the Act, in order that the Purchasers may make routine sales

Company agrees that it will:

the Commission thereunder;

accordance with the instructions furnished by such Holder.

            10.11 Mergers. The Company shall not, directly or indirectly, enter
into any merger, consolidation or reorganization in which the Company shall not
be the surviving corporation unless the proposed surviving corporation shall,
prior to such merger, consolidation or reorganization, agree in writing to
assume the obligations of the Company under this Section 10 and for that purpose
references hereunder to "Shares" shall be deemed to be references to the
securities which such Holders would be entitled to receive in exchange for
Shares under any such merger, consolidation or reorganization.

            10.12 Further Agreements of the Company. If the Company hereafter
becomes subject to the reporting requirements of the Exchange Act, or successor
provision of law, the Company further agrees as follows:

                 FIRST AMENDMENT TO PURCHASE AND SALE AGREEMENT

      THIS FIRST AMENDMENT TO PURCHASE AND SALE AGREEMENT (the "Amendment") is
made as of this 28th day of October, 1994, by and between PIONEER ASSOCIATES
("Pioneer Associates"), and SEAMED CORPORATION, a Delaware corporation (the
"Company"). Unless otherwise defined herein, all capitalized terms shall have
the meanings that are ascribed to them in the Agreement, as defined below.

                                    RECITALS

      A. On January 20, 1978, Pioneer Investment Corp. ("Pioneer Investment")
and Doan Resources Corporation ("Doan") (collectively, the "Purchasers") and
Cynergy, Inc. ("Cynergy") entered into that certain Purchase and Sale Agreement
(the "Agreement"), whereby the Purchasers each purchased a subordinated note in
the principal amount of $62,500 (individually, the "Note") and 142 shares of
Cynergy's common stock (individually, the "Stock"), and were each granted a
warrant for the right to purchase 141 of Cynergy's common stock (individually,
the "Warrant"). Cynergy has since changed its name to SeaMED Corporation and has
declared a 500 for 1 stock split.

      B. Doan assigned all of its right title and interest in and to its Note,
Stock and Warrant to Pioneer Investment, which subsequently assigned all of its
right title and interest in and to the Doan Note, the Doan Stock and the Doan
Warrant and its Note, Stock and Warrant to Pioneer Associates.

      C. The Company has since satisfied in full its obligations under the Doan
Note and the Pioneer Investment Note and Pioneer Associates has exercised the
Doan Warrant and the Pioneer Investment Warrant.

      D. The Company has engaged an investment banking firm, Allen & Company, to
raise an additional $2,000,000 of equity financing through the sale of Class D
Convertible Preferred Stock. The Company shall use the proceeds from such sale
to reduce its outstanding borrowings under its various credit lines, to purchase
equipment and as general working capital.

      E. As a shareholder of the Company, Pioneer Associates expects to benefit,
directly and indirectly, from the sale of the preferred stock.

      F. In order to facilitate the sale of the preferred stock, the parties
desire to amend the Agreement pursuant to the terms and conditions of this
Amendment.

                                   AGREEMENT

      NOW, THEREFORE, in consideration of the mutual covenants contained herein,
and for other good and valuable consideration, the receipt and sufficiency of
which is hereby acknowledged, the parties hereto agree as follows:
