         (c)      NARRATIVE DESCRIPTION OF BUSINESS

PRODUCTS AND SERVICES

         The Company develops, manufactures, markets, and services measurement,
analytical, monitoring, sample preparation and consulting products used to
detect, measure, and analyze gases and chemical compounds.

         PERMEATION PRODUCTS

         Permeation products consist of systems and services designed to measure
the rate of transmission of various gases and vapors through packages and
various materials. These products are designed to perform these measurements
under precise temperature and relative humidity conditions. The principal market
for these products consists of manufacturers of packaging materials, including
manufacturers of papers, plastics and coatings, and the users of such packaging
materials in the food, beverage, pharmaceutical and chemical industries. The
Company also provides certain laboratory testing services utilizing the
Company's permeation products. These services are primarily in the area of
testing film and package permeation. Users of these services are primarily those
companies with insufficient volume to warrant purchasing the Company's products
or others not familiar with such equipment. Other users include companies that
have purchased the Company's products but have a need for additional capacity.
Permeation products accounted for approximately 63%, 60%, and 69% of the
Company's consolidated sales in 1999, 1998, and 1997, respectively. Permeation
instruments currently manufactured by the Company include OX-TRAN(R) systems for
oxygen transmission rates, PERMATRAN-W(R) systems for water vapor transmission
rates, PERMATRAN-C(TM) systems for carbon dioxide transmissions rates, and
AROMATRAN(R) systems for transmission rates of volatile organics and vapors.

         WEIGHING PRODUCTS

         Weighing products manufactured by the Company are used to automatically
determine the weight of pharmaceutical capsules and/or tablets and to reject
those found to be out of acceptable limits. The Company's VERICAP(R) high-speed
capsule weighing system runs at rates up to 2,000 capsules per minute and can be
integrated into a capsule production line in pharmaceutical factories. The other
weighing systems are designed for off-line use. These products are marketed
primarily to the pharmaceutical industry. Weighing products accounted for less
than 15% of the Company's consolidated sales in 1999 and approximately 19% and
15% of the Company's consolidated sales in 1998 and 1997, respectively. Weighing
instruments currently manufactured by the Company include the VERICAP(R)
high-speed capsule weighing systems, the VERITAB(R) high-speed tablet weighing
systems, and the AB(TM) automatic balance weighing systems for tablets or
capsules.

         CONSULTING AND ANALYTICAL SERVICES

         The Company provides consulting and analytical services, on a special
project basis, for customers that require unique problem solving capabilities.
The Company's services may relate to absorption or diffusion of various
compounds, harsh environment applications, shelf-life concerns, flavor or odor
detection, contract research or special permeation applications. In providing
the consulting and analytical services, the Company uses its most advanced
measurement technologies, including proprietary TRANSORPTION(R) technology. The
principal market for the consulting and


                                       3
<PAGE>


analytical services consists of manufacturers of foods, beverages,
pharmaceuticals, plastics, chemicals, electronics, and personal care products.

         HEAD SPACE ANALYZER PRODUCTS

         The Company's headspace analyzers are used to analyze the amount of
oxygen and/or carbon dioxide present in the headspace of flexible and rigid
packages. Some analyzers measure the oxygen and/or carbon dioxide content in
flushing gases used in modified or controlled atmosphere packaging. The
principal market for these products consists of packagers of foods, beverages
and pharmaceuticals. The headspace analyzer products currently manufactured by
the Company include the PAC CHECK(TM) series of headspace analyzers and the
GSA(TM) series of on-line gas stream analyzers for continuous and intermittent
monitoring of modified atmosphere packaging (MAP) and other gas flushing
operations.

         SAMPLE PREPARATION PRODUCTS

         The Company designs, manufactures, markets, and services sample
preparation products. These products consist of hardware and software interfaces
that combine the separations capability of chromatography with the power to
identify individual components by spectroscopy analysis. The most time-consuming
part of chemical analysis is sample preparation. Procedures, techniques, and
instruments that reduce total sample preparation time are highly desirable for
analysis of chemical compounds. The Company's products provide fully automatic
sample collection from any Liquid Chromatograph or Gel Permeation Chromatograph
in a form suitable for immediate examination by Fourier transform infra-red
spectroscopy ("FTIR") and/or matrix assisted laser desorption ionization mass
spectrometry ("MALDI-MS"). The principal market for these products is to
analytical laboratories of polymer and adhesive manufacturers. The sample
preparation products currently manufactured by the Company are the LC-Transform
for interfacing to FTIR and the LC-Transform for interfacing to MALDI-MS.

         GC ANALYZER PRODUCTS

         The Company integrates its gas chromatography components with GCs to
form multidimensional GC analyzer systems. Multidimensional GC analyzers
represent state of the art technology in gas chromatographic separations. These
systems are used in identifying compounds causing off-odors in various products,
in identifying critical aroma compounds and in high purity analysis of single
component matrixes. The GC analyzer products currently manufactured by the
Company are the AROMATRAX(TM) systems for odor and aroma analysis and profiling,
the PURI-TRAX(TM) systems consisting of a vinyl chloride monomer purity analysis
system and a system for measuring trace levels of oxygenated hydrocarbons in a
variety of hydrocarbon products and process streams such as liquefied petroleum
gases, and the VAPO-JECT(TM) automated vaporizing injector system for permanent
and liquefied petroleum gases.

         The principal markets for the GC analyzer products consist of food,
beverage, petroleum, chemical and petrochemical manufacturers. The Company does
not manufacture gas chromatographs but purchases such components from Agilent
Technologies, Inc. pursuant to a Channel Partner arrangement.


                                       4

         GAUGING PRODUCTS

         The Company's gauging products use capacitance technology to measure
the thickness of thin films and coatings in laboratories. These gauges measure
all types of non-metallic materials, with very repeatable gauge readings at
thickness resolutions up to one millionth of an inch. Software packages allow
the display of each material's profile and provide analysis of the related data.
The principal market for the gauging portion of this product group is made up of
manufacturers of plastic films. The Company currently manufactures the
PROFILER(R) 140E laboratory gauge.

         LEAK DETECTION PRODUCTS

         The leak detection products manufactured by the Company detect leaks in
pouches, blister packs and a wide range of other packages. The principal market
for these products includes packagers of food, pharmaceuticals and sterile
medical supplies. The Company manufactures two types of leak detection
instruments. One is a non-destructive leak detector that senses small amounts of
carbon dioxide escaping from a package. The carbon dioxide may be present in the
headspace of the package or forced inside the package by carbon dioxide
pressurization. The second instrument detects leaks and checks for seal
integrity by applying and measuring pressure within the packages.

COMPETITION

         The Company experiences competition in both foreign and domestic
markets from one or more competitors with respect to all of its products and
services. The Company competes with several others in the design, manufacture
and sale of its measurement, analytical, monitoring, sample preparation and
consulting products. The principal competitive factors are product technology
and performance, quality and reliability, sales and marketing ability, product
support, delivery, and price. Some of the Company's competitors have greater
assets and resources than the Company and some are smaller than the Company.
Some of the Company's larger competitors may have greater financial resources,
stronger marketing organizations, broader product lines and other resources than
those of the Company.

MANUFACTURING AND SUPPLIES

         The Company manufactures products at three locations in the United
States. The Company's manufacturing capabilities include electro-mechanical
assembly, testing, integration of components and systems, calibration, and
validation of systems. Certain components are currently purchased from single
source suppliers. An interruption of one of these sources could result in delays
in the Company's production while the Company developed an alternative supplier
and could result in a loss of sales and income. There are other single source
components for which the Company has determined that other sources are readily
available. The Company has experienced no significant production delays because
of a supplier's inability to ship an acceptable component.

MARKET RISK MANAGEMENT

         Substantially all of the Company's marketable securities are at fixed
interest rates and therefore the fair value of these instruments is affected by
changes in market interest rates. However, almost all of the Company's
marketable securities mature within three years.


                                       5
<PAGE>


Accordingly, the Company believes that the market risk arising from its holding
of these financial instruments is minimal.

         The Company currently sells its products and services in United States
dollars; accordingly, the exposure to foreign currency exchange risk is minimal.

BACKLOG

         The Company had a total backlog of approximately $1,980,000 as of
December 31, 1999 for all of its products as compared to approximately
$1,952,000 and $398,000 as of December 31, 1998 and 1997, respectively. The
Company anticipates filling the entire current backlog in 2000.

PATENTS AND LICENSES

         Generally, the Company believes that the protection afforded by patent
rights is important to its business and it will continue to seek patent
protection for its technology and products. The Company has required certain
employees and consultants to assign to the Company all inventions that are
conceived and developed during their employment, except to the extent prohibited
by applicable law. The Company holds both United States and international
patents and has both U.S. and international patents pending. The Company
currently holds 37 U.S. patents and 24 international patents. In addition, the
Company holds license rights under four U.S. patents subject to royalty payments
and/or minimum required royalties. These patents and licenses will expire during
the period from 2000 through 2018.

         Even though the Company has obtained the patents mentioned above, there
can be no guarantee that these patents will keep competitors from producing
substantially similar products. Although it can offer no assurance, the Company
believes its products do not infringe on patents owned by any other persons. Any
determination that a material component of the Company's products infringes upon
the rights of others could have a material adverse effect upon the Company. In
the event that the Company's products may be covered in whole or in part by
patents owned by others, the Company may find it desirable to obtain licenses
with respect to such patents.

         The Company also owns or has applied for certain trademarks which
protect and identify its products, including the trademark MOCON(R), which the
Company has designated as a house trademark under which all its products
manufactured at its headquarters are sold, and the trademarks and servicemarks
VERICAP(R), OX-TRAN(R), PERMATRAN-W(R), PROFILER(R), COULOX(R), HERSCH(R),
VERITAB(R), AROMATRAN(R), SKYE(R), PAC CHECK 200(R), LC-Transform(R),
TRANSORPTION(R) and 1-TIME(R). The Company's trademarks have a life, subject to
periodic maintenance, of 10 to 20 years, which may be extended.

RESEARCH AND DEVELOPMENT

         The Company incurred expenses of approximately $1,234,000, $1,061,000
and $1,016,000 during the fiscal years ended December 31, 1999, 1998 and 1997,
respectively, for research and development of its products. Research and
development costs were 7% of sales for the fiscal year ended December 31, 1999
and were 7% and 6%, respectively, for the preceding two fiscal years. For the
foreseeable future, the Company expects to allocate, on an annual basis,
approximately 5% to 8% of sales to research and development.


                                       6

WORKING CAPITAL PRACTICES

         The Company maintains inventory levels in its product groups consistent
with projected sales. The Company's standard domestic payment terms are net 30
days. International sales are transacted pursuant to letters of credit in some
cases. The Company generally warrants its products for one year from the date of
shipment. There have been few instances when the Company was required to accept
the return of merchandise that failed to comply with the Company's warranty.

FOREIGN AND DOMESTIC MARKETING

         The Company markets its products and services, provides support
services, and distributes expendables and accessories required to support the
operation of the products. The Company sells its products in the United States
and Canada through a direct sales channel to end-users. A network of independent
representatives serves the Company's foreign markets. To the Company's
knowledge, no independent sales representative of the Company sells a material
amount of products manufactured by the Company's competitors.

         The Company's wholly-owned subsidiary, MoCon FSC, Inc., a Barbados
corporation ("FSC") carries out all the foreign distribution of the Company's
products. The Company acts as the selling agent of FSC.

         The Company makes all foreign sales in U.S. dollars and consequently
does not hedge against exchange rate fluctuations. Nonetheless, should the value
of the dollar rise relative to other currencies, the Company's sales abroad
would be negatively impacted. Additionally, the Company can give no assurances
that foreign tariff, trade or tax policies or foreign economic conditions will
not negatively affect sales and earnings of the Company in the future.

         For information concerning the Company's export sales by geographic
area, see Note 9 of the Notes to Consolidated Financial Statements contained on
page F-16. No single customer accounts for 10% or more of the Company's
consolidated revenues and the Company does not believe that the loss of any
single customer would have a material adverse effect on the Company. One of the
Company's independent representatives accounted for approximately 17% of the
Company's sales in fiscal 1999. For additional information concerning sales by
such independent representatives, see Note 9 of the Notes to Consolidated
Financial Statements contained on page F-16. The Company's business is not
seasonal in nature.

EMPLOYEES

         As of December 31, 1999, the Company had 88 full-time employees. The
Company employs scientists and engineers who research and develop potential new
products. To protect the Company's proprietary information, the Company has
confidentiality and non-compete agreements with its employees. None of the
Company's employees are represented by a labor union, and the Company considers
its employee relations to be satisfactory.

ITEM 2.  PROPERTIES

         The Company leases 54,900 square feet of office, engineering,
laboratory, and production space in Minnesota, Massachusetts, and Texas.
Management believes that the Company's facilities


                                       7
<PAGE>


are generally adequate for its present operations and that suitable space is
readily available if any of such leases are not extended.

         The Company headquarters and operations occupy approximately 47,200
square feet of space in Minneapolis, Minnesota. The current lease expires in
June 2010.

         Microanalytics' operations occupy approximately 2,400 square feet of

ITEM 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
         OF OPERATIONS

         This Form 10-K includes certain statements that are deemed to be
"forward-looking statements" within the meaning of Section 27A of the Securities
Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934,
as amended. All statements, other than statements of historical facts, included
in this Form 10-K that address activities, events, or developments that the

forward-looking statements. These statements are based on certain assumptions
and analyses made by the Company in light of its experience and its perception
of historical trends, current conditions, expected future developments, and
other factors it believes are appropriate in the circumstances. Such statements
are subject to a number of assumptions, risks, and uncertainties, many of which
are beyond the control of the Company. Investors are cautioned that any such
statements are not guarantees of future performance and that actual results or
developments may differ materially from those projected in the forward-looking
statements.

SUMMARY

         On January 28, 1998 the Company acquired Microanalytics Instrumentation
Corp. of metro Austin, Texas and on December 7, 1998 the Company acquired Lab
Connections, Inc. of metro Boston, Massachusetts. The acquisitions were recorded
using the purchase method of accounting and, accordingly, their results of
operations have been included since the acquisition dates. Sales increased 18%
in 1999 compared to 1998, while net income increased 25% for the same period.
The Company's financial position as of December 31, 1999 reflects a decrease in
working capital to $8,035,000 compared to $8,931,000 at December 31, 1998. Basic
earnings per share were $0.46 in 1999, $0.37 in 1998, and $0.58 in 1997.

RESULTS OF OPERATIONS

         Net sales were $17,843,000 in 1999, compared to $15,146,000 in 1998,
and $17,017,000 in 1997. The increase in sales from 1998 to 1999 was due
primarily to increases in the sales volume of the Company's permeation,
consulting and analytical service products, and the sales volume of Lab
Connections, a wholly-owned subsidiary of the Company. The decrease in sales
from 1997 to 1998 was primarily attributable to decreases in the sales volume of
the Company's permeation products, offset somewhat by an increase in the sales
volume of the Company's weighing products and the addition of Microanalytics in
January, 1998. In 1999, international sales increased 28% to $7,207,000 and
domestic sales increased 12% to $10,636,000. International and domestic sales
each decreased 11% in 1998 to $5,624,000, and $9,522,000, respectively.

         Sales of the Company's permeation products increased in 1999 due to
expanded market penetration with lower priced, less precise multiple test
station products. The Company is positioning its permeation products to address
applications outside the traditional measurement of barrier packages and
materials. Products have been introduced to analyze high transmitting


                                       10
<PAGE>


materials such as surgical gowns and diaper lining. Permeation products
accounted for approximately 63%, 60%, and 69% of the Company's consolidated
sales in 1999, 1998, and 1997, respectively.

         Weighing product sales decreased in 1999 due to declining sales of the
VERICAP high-speed capsule weighing and sorting system. Weighing products
accounted for approximately 10%, 19% and 15% of the Company's consolidated sales
in 1999, 1998, and 1997, respectively.

         Consulting and Analytical Services revenues increased in 1999 as
expertise in the analysis of materials expanded. Applications using the
Company's most advanced technologies are positioning the Company to address
other markets such as life sciences, medical and electronics. A significant
portion of the revenues from these products are from customers outside of the
Company's traditional measurements of barrier packages and materials.

         Sales of headspace analyzer products remained steady in 1999 compared
to 1998. GC analyzer product sales increased in 1999 due to increased market
penetration. Sales of sample preparation products increased in 1999 due to the
acquisition of these products in late 1998.

         International revenues increased 28% to $7,207,000, or 40% of total
revenue in 1999 compared to $5,624,000, or 37% of revenue in 1998, and
$6,314,000, or 37% of total revenue in 1997. The Company uses a network of
independent representatives to market and service its products in foreign
countries. A single currency called the euro was introduced in Europe on January
1, 1999. Although, MOCON sells its products in United States dollars, the
increased price transparency resulting from the use of a single currency may
affect the ability of its independent representatives to price products
differently in the various European markets. The use of a single European
currency may increase the foreign currency risks of such independent
representatives and affect the prices at which products are sold.

         The gross profit margin was 65% in 1999 compared to 65% in 1998, and
67% in 1997. Over the past several years the Company's gross profit percentage
has been in a range of about 62 to 67 percent of sales. The 1997 gross profit
margin was at the high end of the historical range due to reduced warranty
expenses.

         Selling, general and administrative ("SG&A") expenses were $6,479,000
in 1999 or 36% of revenue, compared to $5,747,000, or 38% of revenue in 1998,
and $5,480,000, or 32% of revenue in 1997. The increase in SG&A expenses from
1998 to 1999 is primarily due to higher commission expenses resulting from the
increase in sales and due to the amortization of intangible assets related to
the acquisition of Lab Connections. The increase in SG&A expenses from 1997 to
1998 resulted from the addition of regional sales management, the addition of
sales representatives, and an increase in travel and legal fees incurred to
protect confidential information of the Company. The Company may continue to
incur legal fees associated with this cause throughout 2000.

         Research and development expenses amounted to $1,234,000, or 7% of
revenue in 1999, compared to $1,061,000, or 7% of revenue in 1998, and
$1,016,000, or 6% of revenue in 1997. For the foreseeable future, the Company
expects to allocate on an annual basis approximately 5 to 8 percent of sales to
research and development.


                                       11
<PAGE>


         Investment income decreased to approximately $419,000 in 1999 from
$470,000 in 1998. The decrease in 1999 is primarily due to lower average
investment balances during 1999. The decrease in investment income from 1997 to
1998 is the result of a one-time gain of approximately $235,000 realized in 1997
on the sale of equity securities, and to a lesser extent is due to a lower
average yield on investments in 1998.

         The Company's provision for income taxes was 33.5% of income before
income taxes in 1999 and was 34% of pretax income in 1998 and 1997. Based on
current operating conditions and income tax laws, the Company expects the tax
rate for 2000 to be in the range of 32 to 34%.

         Net income was $2,899,000 in 1999 compared to $2,328,000 in 1998, and
$3,728,000 in 1997. Basic net income per share was $.46 per share in 1999
compared to $.37 per share in 1998, and $.58 per share in 1997.

LIQUIDITY AND CAPITAL RESOURCES

         Total cash, temporary cash investments and marketable securities
increased $508,000 during 1999 to $9,883,000. The increase is primarily
attributable to the Company's net income. In addition to funding its operations,
the Company used its cash resources to pay dividends totaling $1,252,000 and to
repurchase shares of the Company's common stock during the period totaling
approximately $1,524,000. Depending upon market conditions and subject to
approval of the Board of Directors, the Company may continue to repurchase
shares of its Common Stock on the open market at prices not exceeding the market
price.

         Cash flow from operations has historically been sufficient to meet
liquidity requirements, capital expenditures and research and development costs.
Cash flow from operations totaled $3,783,000, $3,222,000 and $2,686,000 in 1999,
1998 and 1997, respectively.

         The Company has no long-term debt and has no material commitments for
capital expenditures as of December 31, 1999. The Company's plant and equipment
does not require any major expenditures to accommodate a significant increase in
operating demands. The Company anticipates that a combination of its existing
cash, temporary cash investments and marketable securities, plus an expected
continuation of cash flow from operations, will continue to be adequate to fund
operations, capital expenditures and dividend payments in the foreseeable
future.

NEW ACCOUNTING PRONOUNCEMENTS

         In December 1999, the SEC staff issued Staff Accounting Bulletin (SAB)
No. 101, REVENUE RECOGNITION IN FINANCIAL STATEMENTS. SAB No. 101 summarizes
certain of the SEC staff's views in applying generally accepted accounting
principles to revenue recognition in financial statements. The Company will
implement SAB No. 101 in the first quarter of 2000 and is currently in the
process of evaluating the impact.

         During 1998, the Financial Accounting Standards Board (FASB) issued
Statement of Financial Accounting Standards (SFAS) No. 133, ACCOUNTING FOR
DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES (as amended by SFAS No. 137 with
respect to the effective date), which establishes new standards for recognizing
all derivatives as either assets or liabilities, and measuring those instruments
at fair value. The Company will be required to adopt the new standard beginning
with the first quarter of fiscal 2001. The Company is currently in the process
of evaluating the impact of this statement. Its adoption is not expected to
materially impact the Company's financial condition or results of operations.


                                       12

CERTAIN IMPORTANT FACTORS

         In connection with the "safe harbor" provisions of the Private
Securities Litigation Reform Act of 1995, the Company wishes to caution readers
that the following important factors, among others, in some cases have affected,
and in the future could affect, the Company's actual results and could cause its
actual results in 2000 and beyond to differ materially from those expressed in
any forward-looking statements made by, or on behalf of, the Company.

         CHANGING PRICES/EFFECT OF INFLATION. Inflation has not had a material
impact on the Company's operations. The prices of some components purchased by
the Company have increased in the past several years due in part to decreased
volume. Certain other material and labor costs have increased, but the Company
believes that such increases are approximately consistent with overall inflation
rates. The Company believes that competition based on price is a significant
factor affecting its customers' buying decisions. There is no assurance that the
Company can pass along cost increases in the form of price increases or sustain
profit margins that have been achieved in prior years.

         GROWTH POTENTIAL. The analytical and measurement instrument markets in
which the Company operates have been somewhat flat in recent years. The Company
has identified a number of strategies it believes will allow it to grow its
business, including developing new products and technologies, developing new
applications for its technologies, acquiring complementary businesses or product
lines, and strengthening its sales force. No assurance can be given that the
Company will be able to successfully implement these strategies, or that these
strategies will result in growth of the Company's business.

         ACQUISITION STRATEGY. One of the Company's growth strategies is to
supplement its internal growth with the acquisition of businesses and
technologies that complement or augment the Company's products. Certain
businesses recently acquired by the Company have produced net operating losses
or low levels of profitability. In addition, businesses that the Company may
seek to acquire in the future may also be marginally profitable or unprofitable.
In order for any acquired business to achieve the level of profitability desired
by the Company, the Company must successfully change operations of the acquired
companies and improve their market penetration. No assurance can be given that
the Company will be successful in this regard. In addition, promising
acquisitions are difficult to identify and complete for a number of reasons,
including competition among prospective buyers. There can be no assurance that
the Company will be able to complete future acquisitions. In order to finance
any such acquisitions, it may be necessary for the Company to raise additional
funds either through public or private financing. Any equity or debt financing,
if available at all, may be on terms that are not favorable to the Company and
may result in dilution to the Company's shareholders.


                                       13
<PAGE>


         TECHNOLOGICAL CHANGE, OBSOLESCENCE, AND THE DEVELOPMENT AND ACCEPTANCE
OF NEW PRODUCTS. The market for the Company's products and services is
characterized by rapid and significant technological change and evolving
industry standards. New product introductions responsive to these factors
require significant planning, design, development and testing at the
technological, product, and manufacturing process levels, and may render
existing products and technologies uncompetitive or obsolete. There can be no
assurance that the Company's products will not become uncompetitive or obsolete.
In addition, industry acceptance of new technologies developed by the Company
may be slow to develop due to, among other things, existing regulations or
standards written specifically for older technologies and general unfamiliarity
of users with new technologies.

         DEPENDENCE ON CAPITAL SPENDING POLICIES AND GOVERNMENT FUNDING. The
Company's customers include pharmaceutical, food, and chemical companies,
laboratories, government agencies, and public and private research institutions.
The capital spending of these entities can have a significant effect on the
demand for the Company's products. Any decrease in capital spending by any of
the customer groups that account for a significant portion of the Company's
sales could have a material adverse effect on the Company's business and results
of operations.

         INTERNATIONAL SALES. Sales outside the United States accounted for
approximately 40% of the Company's revenues in 1999 and for approximately 37% of
the Company's revenues in 1998 and 1997. The Company expects that international
sales will continue to account for a significant portion of the Company's
revenues in the future. Sales to customers in foreign countries are subject to a
number of risks, including the following: agreements may be difficult to enforce
and receivables difficult to collect through a foreign country's legal system;
foreign customers may have longer payment cycles; impose tariffs, or adopt other
restrictions on foreign trade; fluctuations in exchange rates may affect product
demand; export licenses, if required, may be difficult to obtain and the
protection of intellectual property in foreign countries may be more difficult
to enforce. There can be no assurance that any of these factors will not have a
material adverse effect on the Company's business and results of operations.

         COMPETITION. The Company encounters and expects to continue to
encounter competition in the sale of its products. The Company believes that the
principal competitive factors affecting the market for its products include
product performance, price, reliability, and customer service. The Company's
competitors include large multinational corporations and their operating units.
Some of the Company's competitors have substantially greater financial,
marketing, and other resources than those of the Company. As a result, they may
be able to adapt more quickly to new or emerging technologies and changes in
customer requirements, or to devote greater resources to the promotion and sale
of their products than the Company. In addition, competition could increase if
new companies enter the market or if existing competitors expand their product
lines or intensify efforts within existing product lines. There can be no
assurance that the Company's current products, products under development or
ability to discover new technologies will be sufficient to enable it to compete
effectively with its competitors.

         PROTECTION, DEFENSE, AND USE OF INTELLECTUAL PROPERTY. The Company
holds patents relating to various aspects of its products and believes that
proprietary technical know-how is critical to many of its products. Proprietary
rights relating to the Company's products are protected from unauthorized use by
third parties only to the extent that they are covered by valid and enforceable


                                       14
<PAGE>


patents or are maintained in confidence as trade secrets. There can be no
assurance that patents will issue from any pending or future patent applications
owned by or licensed to the Company or that the claims allowed under any issued
patents will be sufficiently broad to protect the Company's technology, and in
the absence of patent protection, the Company may be vulnerable to competitors
who attempt to copy the Company's products or gain access to its trade secrets
and know-how. Proceedings initiated by the Company to protect its proprietary
rights could result in substantial costs to the Company. There can be no
assurance that competitors of the Company will not initiate litigation to
challenge the validity of the Company's patents, or that they will not use their
resources to design comparable products that do not infringe the Company's
patents. There may also be pending or issued patents held by parties not
affiliated with the Company that relate to the Company's products or
technologies. The Company may need to acquire licenses to, or contest the
validity of, any such patents. There can be no assurance that any license
required under any such patent would be made available on acceptable terms or
that the Company would prevail in any such contest. The Company could incur
substantial costs in defending itself in suits brought against it or in suits in
which the Company may assert its patent rights against others. If the outcome of
any such litigation is unfavorable to the Company, the Company's business and
results of operations could be materially adversely affected. In addition, the
Company relies on trade secrets and proprietary know-how that it seeks to
protect, in part, by confidentiality agreements with its collaborators,
employees, and consultants. There can be no assurance that these agreements will
not be breached, that the Company would have adequate remedies for any breach,
or that the Company's trade secrets will not otherwise become known or be
independently developed by competitors.

         FLUCTUATION OF STOCK PRICE. The Company believes factors such as
announcements of new products by the Company or its competitors, quarterly
fluctuations in the Company's financial results, customer contract awards,
developments in regulation and general conditions in the various markets where
the Company's products are sold have caused and are likely to continue to cause
the market price of the Company's common stock to fluctuate substantially. In
addition, instrumentation company stocks have experienced significant price and
volume fluctuations that often have been unrelated to the operating performance
of such companies. This market volatility may adversely affect the market price
of the Company's common stock.

YEAR 2000 IMPACT

         Computers, software and other equipment utilizing microprocessors that
use only two digits to identify a year in a date field may be unable to
accurately process certain date-based information, including correct leap-year
recognition, at or after the year 2000. This is commonly referred to as the
"Year 2000" problem. The Company has not experienced significant difficulty with
regard to this situation and continues to monitor its business in regard to the
potential impact of the Year 2000 problem on its business.

         INTERNAL SYSTEMS. The Company has not experienced significant Year 2000
issues and the costs incurred to update non-compliant systems were not material.
The Company continues to monitor its systems for Year 2000 problems and does not
expect issues that would have a material adverse impact on the Company's results
of operations and consolidated financial condition. However, there can be no
assurance that unforeseen difficulties or costs will not arise.


                                       15
<PAGE>


         VENDORS. The Company is not aware of any critical suppliers and other
vendors that will not be able to provide the Company with products and services
through the change to 2000 or their inability to provide products to the Company
that are Year 2000 compliant. However such failure, including failure of any
contingency plans, could have a material adverse impact on the Company's results
of operations and consolidated financial condition.

         COMPANY PRODUCTS. Management believes that all of the Company's
products shipped after 1998 are and will continue to be Year 2000 compliant.
Information regarding the Year 2000 status of products shipped prior to 1999 may
be obtained via the Company's web site at www.mocon.com.

         Although the Company is not dependent on any single customer, the
Company does have significant sales in certain industries, including the food,
polymer, paper and pharmaceutical industries. A significant Year 2000 related
disruption in these or other industries into which the Company sells, could have
a material adverse impact on the Company's results of operations and
consolidated financial condition.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

         Substantially all of the Company's marketable securities are at fixed
interest rates and therefore the fair value of these instruments is affected by
changes in market interest rates. However, almost all of the Company's
marketable securities mature within three years. Accordingly, the Company
believes that the market risk arising from its holding of these financial
instruments is minimal.

                          INDEPENDENT AUDITORS' REPORT



The Board of Directors and Stockholders
MOCON, Inc. and subsidiaries:


We have audited the accompanying consolidated balance sheets of MOCON, Inc. (the
Company) and subsidiaries as of December 31, 1999 and 1998, and the related
consolidated statements of income, stockholders' equity and comprehensive
income, and cash flows for each of the years in the three-year period ended
December 31, 1999. These consolidated financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these consolidated financial statements based on our audits.

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

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the financial position of MOCON, Inc. and
subsidiaries as of December 31, 1999 and 1998, and the results of their
operations and their cash flows for each of the years in the three-year period
ended December 31, 1999, in conformity with generally accepted accounting
principles.

                          MOCON, INC. AND SUBSIDIARIES

                   Notes to Consolidated Financial Statements

                        December 31, 1999, 1998, and 1997


(1)   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

      MOCON, Inc. (the Company) operates in a single industry segment: the
      development, manufacturing, and marketing of measurement, analytical,
      monitoring, sample preparation, and consulting products used to detect,
      measure, and analyze gases and chemical compounds for customers in the
      barrier packaging, food, and pharmaceutical industries throughout the
      world. The following is a summary of the significant accounting policies
      used in the preparation of the Company's consolidated financial
      statements.

      (a)   PRINCIPLES OF CONSOLIDATION

            The consolidated financial statements include the accounts of the
            Company and its wholly-owned subsidiaries. All material intercompany
            balances and transactions have been eliminated in consolidation.

      (b)   STATEMENTS OF CASH FLOWS

            The Company considers all highly liquid investments purchased with
            an original maturity of three months or less to be cash equivalents.

            Temporary cash investments consist of short-term investments which
            are readily convertible to cash.

      (c)   MARKETABLE SECURITIES

            Marketable securities at December 31, 1999 consist of United States
            government obligations, municipal bonds, and certificates of
            deposit. The Company classifies its debt and marketable equity
            securities in one of three categories: trading, available-for-sale,
            or held-to-maturity. Trading securities are bought and held
            principally for the purpose of selling them in the near term.
            Held-to-maturity securities are those securities in which the
            Company has the ability and intent to hold until maturity. All other
            securities not included in trading or held-to-maturity are
            classified as available-for-sale.

            Trading and available-for-sale securities are recorded at fair
            value. Held-to-maturity securities are recorded at amortized cost,
            adjusted for the amortization or accretion of premiums or discounts.
            Unrealized holding gains and losses on available-for-sale securities
            are excluded from income and are reported as a separate component of
            stockholders' equity until realized.

            A decline in the market value of any available-for-sale or
            held-to-maturity security below cost that is deemed other than
            temporary is charged to income resulting in the establishment of a
            new cost basis for the security.

            Premiums and discounts are amortized or accreted over the life of
            the related held-to-maturity security as an adjustment to yield.
            Dividend and interest income are recognized when earned. Realized
            gains and losses for securities classified as available-for-sale and
            held-to-maturity are included in income and are derived using the
            specific identification method for determining the cost of
            securities sold.


                                                                     (Continued)

                   Notes to Consolidated Financial Statements

                        December 31, 1999, 1998, and 1997


      (d)   INVENTORIES

            Inventories are stated at the lower of cost or market. Cost is
            determined by the first-in, first-out method.

      (e)   PROPERTY AND EQUIPMENT

            Property and equipment are carried at cost. Depreciation and
            amortization are computed using the straight-line method. When
            assets are retired or otherwise disposed of, the cost and related
            accumulated depreciation are removed from the accounts, and any
            resulting gain or loss is recognized in income for the period. The
            cost of maintenance and repairs is charged to income as incurred and
            significant renewals and betterments are capitalized.

      (f)   INTANGIBLE ASSETS

            Intangible assets are carried at cost less accumulated amortization
            and consist of goodwill, technology rights, patents, and trademarks.
            Goodwill represents the excess of the purchase price over the fair
            value of assets acquired. Costs incurred in connection with
            applications for new patents are deferred until a final
            determination, with respect to the application, is made by
            appropriate regulatory agencies. Costs of patents abandoned are
            charged to income in the period of abandonment. Goodwill and
            technology rights are amortized on a straight-line basis over 7 to
            10 years. Patent costs are amortized over the lesser of 17 years or
            their estimated useful lives using the straight-line method.
            Trademarks are amortized over five years.

      (g)   INCOME TAXES

            The Company uses the asset and liability method for computing its
            deferred taxes. Under the asset and liability method, deferred taxes
            are based on the difference between the financial statement and tax
            basis of assets and liabilities and the enacted tax rates that will
            be in effect when these differences reverse. Deferred tax expense
            represents the change in deferred tax assets and liabilities during
            the year.

      (h)   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.


                                                                     (Continued)

                   Notes to Consolidated Financial Statements

                        December 31, 1999, 1998, and 1997


      (i)   IMPAIRMENT OF LONG-LIVED ASSETS AND LONG-LIVED ASSETS TO BE DISPOSED
            OF

            The Company reviews its long-lived assets and certain identifiable
            intangibles for impairment whenever events or changes in
            circumstances indicate that the carrying amount of an asset may not
            be recoverable. Recoverability of assets to be held and used is
            measured by a comparison of the carrying amount of an asset to
            future net cash flows expected to be generated by the asset. If such
            assets are considered to be impaired, the impairment to be
            recognized is measured by the amount by which the carrying amount of
            the assets exceeds the fair value of the assets. Assets to be
            disposed of are reported at the lower of the carrying amount or fair
            value less costs to sell.

      (j)   FAIR VALUE OF FINANCIAL INSTRUMENTS

            The Company's financial instruments are recorded in its consolidated
            balance sheet. The carrying amount for cash and temporary cash
            investments, accounts receivable, accounts payable, and accrued
            liabilities approximates fair value due to the immediate or
            short-term maturity of these financial instruments. The fair values
            of investments in marketable securities are based on quoted market
            prices and are summarized in note 2.

      (k)   REVENUE RECOGNITION

            Revenue is recognized upon shipment of product or upon completion of
            services.

      (l)   ADVERTISING COSTS

            The Company incurs advertising costs associated with trade shows,
            print advertising, and brochures. Such costs are charged to expense
            as incurred. Advertising expense was $192,000, $219,000, and
            $219,000, in 1999, 1998, and 1997, respectively.

      (m)   NET INCOME PER COMMON SHARE

            Basic net income per common share is computed by dividing net income
            by the weighted average of common shares outstanding during the
            year. Diluted net income per share is computed by dividing net
            income by the weighted average of common and dilutive potential
            common shares outstanding during the year.

      (n)   STOCK-BASED EMPLOYEE COMPENSATION

            The Company uses the intrinsic-value method for employee stock-based
            compensation pursuant to APB Opinion No. 25, ACCOUNTING FOR STOCK
            ISSUED TO EMPLOYEES. Under the guidelines of Opinion 25,
            compensation cost for stock-based employee compensation plans is
            recognized based on the difference, if any, between the quoted
            market price of the stock on the date of grant and the amount an
            employee must pay to acquire the stock. The Company adopted the
            disclosure provisions for employee stock-based compensation and the
            fair-value method for nonemployee stock-based compensation of
            Statement of Financial Accounting Standards (SFAS) No. 123,
            ACCOUNTING FOR STOCK-BASED COMPENSATION.


                                                                     (Continued)

                        December 31, 1999, 1998, and 1997


      (o)   RECLASSIFICATIONS

            Certain 1998 and 1997 amounts have been reclassified to conform to
            the 1999 presentation.

      (p)   NEW ACCOUNTING PRONOUNCEMENTS

            In December 1999, the SEC staff issued Staff Accounting Bulletin
            (SAB) No. 101, REVENUE RECOGNITION IN FINANCIAL STATEMENTS. SAB No.
            101 summarizes certain of the SEC staff's views in applying
            generally accepted accounting principles to revenue recognition in
            financial statements. The Company will implement SAB No. 101 in the
            first quarter of 2000 and is currently in the process of evaluating
            the impact.

            During 1998, the Financial Accounting Standards Board (FASB) issued
            Statement of Financial Accounting Standards (SFAS) No. 133,
            ACCOUNTING FOR DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES (as
            amended by SFAS No. 137 with respect to the effective date), which
            establishes new standards for recognizing all derivatives as either
            assets or liabilities, and measuring those instruments at fair
            value. The Company will be required to adopt the new standard
            beginning with the first quarter of fiscal 2001. The Company is
            currently in the process of evaluating the impact of this statement.
            Its adoption is not expected to materially impact the Company's
            financial condition or results of operations.

(2)   MARKETABLE SECURITIES

      holding losses, and fair value for available-for-sale and held-to-maturity
      securities by major security type at December 31, 1999 and 1998 were as

      The Company has determined that establishing a valuation allowance for the
      deferred tax assets is not required since it is more likely than not that
      the deferred tax assets will be realized through future taxable income.
      Net operating loss and tax credit carryforwards aggregated $145,000 and
      $25,000, respectively, at December 31, 1999. These carryforwards are
      subject to certain IRS usage limitations and begin to expire in 2012.

(7)   STOCKHOLDERS' EQUITY

      On May 19, 1998, the number of authorized shares of capital stock was
      increased from 10,000,000 shares to 25,000,000 shares, consisting of
      22,000,000 shares of common stock with a $.10 par value and 3,000,000
      shares undesignated as to series.

      As of December 31, 1999, the Company has reserved 351,883 shares of common
      stock for options that are still available for grant under the Company's
      stock option plans, and 228,893 shares for options that have been granted
      but have not yet been exercised.


                                                                     (Continued)

                          MOCON, INC. AND SUBSIDIARIES

                   Notes to Consolidated Financial Statements

                        December 31, 1999, 1998, and 1997


      Under the plans, option exercise prices are 100% of the market value of
      the common stock at the date of grant, except for incentive options
      granted under the 1992 and 1998 Plans to persons owning more than 10% of
      the Company's stock, in which case the option price is 110% of the market
      value, and nonqualified options granted under the 1992 and 1998 Plans,
      which may be granted at option prices no less than 25% of the market
      value. Exercise periods are generally for five to ten years. Certain of
      the plans allow for the granting of nonqualified stock options. Upon the
      exercise of these nonqualified options, the Company may realize a
      compensation deduction allowable for income tax purposes. The after-tax
      effect of these tax deductions is included in the accompanying
      consolidated financial statements as an addition to capital in excess of
      par value.

      The Company has adopted the disclosure-only provisions of SFAS No. 123,
      ACCOUNTING FOR STOCK-BASED COMPENSATION. Accordingly, no compensation cost
      has been recognized with respect to the Company's stock option plans. Had
      compensation cost for these plans been determined based on the fair value
      methodology prescribed by SFAS 123, the Company's net earnings and
      earnings per share would have been reduced to the pro forma amounts
      indicated below:

                                          1999          1998           1997

      The pro forma amounts may not be representative of the effects on reported
      net earnings for future years. The fair value of each option grant is
      estimated on the date of grant using the binomial option-pricing model
      with the following weighted-average assumptions used for grants in 1999,
      1998, and 1997:

(11)    ACQUISITION

        On December 7, 1998, the Company acquired Lab Connections, Inc.
        (LabCon), a manufacturer of instruments used to automate sample
        preparation from liquid chromatography for analysis by spectroscopy, of
        Marlborough, Massachusetts. Under the terms of the agreement, the
        Company exchanged $1,112,882 and 174,994 shares of the Company's common
        stock with a market value of approximately $951,530 for all of the
        capital stock of LabCon. The acquisition was recorded using the purchase
        method of accounting and, accordingly, the acquired operations of LabCon
        have been included in the results of operations since the date of
        acquisition. The purchase price has been allocated to the net assets
        acquired based on estimated fair market values at the date of
        acquisition. The cost of acquired intangible assets will be amortized on
        a straight-line basis over 7 to 10 years. In addition, the Company
        acquired Microanalytics Instrumentation Corp. (Micro) on January 28,
        1998 for aggregate consideration of $92,875 payable in common stock and
        cash. The estimated fair values of assets and liabilities acquired in
        these acquisitions are summarized as follows:
