ITEM 1 BUSINESS

DEVELOPMENT OF BUSINESS

         Initially formed in November 1980, under the name Sinex Corp., Sentex
Sensing Technology, Inc., a New Jersey corporation (the "Company"), commenced
the commercial production of a portable explosives detector of its own design,
the T-54. In April 1984, the Company sold, in its initial public offering,
25,000,000 Common Shares, no par value of the Company (the "Common Shares").
Through fiscal 1996, the Company generally conducted the operations of its
business through Sentex Systems, Inc., a Delaware corporation and wholly owned
subsidiary of the Company ("Systems").

         On March 1, 1996, certain shareholders of the Company sold a
substantial portion of their shares to CPS Capital, Ltd., an Ohio limited
liability company, ("CPS"). As a result of such acquisition, CPS has become the
principal shareholder of the Company. CPS is controlled by Robert S. Kendall,
the Chairman and Chief Executive Officer of the Company.

         Effective November 30, 1996, Monitek Technologies, Inc., a Delaware
corporation ("Monitek") became a wholly owned subsidiary of the Company,
pursuant to a merger (the "Merger") of a wholly owned subsidiary of the Company
with and into Monitek. Monitek is now operating as a wholly owned subsidiary of
the Company. Monitek also operates a portion of its business through a wholly
owned German subsidiary of Monitek named Monitek GmbH, which over the last three
years has accounted for approximately 60% of Monitek's total revenues. Monitek
designs, develops, assembles and markets instruments for the measurement of
clarity (turbidity), suspended solids content, color, purity, flow, level and
volume of liquids in industrial and waste water environments.

         In March 1998, the Company purchased Cypress Instruments, Inc.
("Cypress") for the purpose of acquiring a new product line, which has
subsequently been folded into the Monitek product line.

         On September 4, 1998, the Company completed the sale of all of the
outstanding capital stock of Systems to ALR Group Incorporated ("ALR"), which is
principally owned by Amos Linenberg ("Linenberg"). Prior to the sale, Linenberg
was the President of Systems and an Executive Vice President of the Company. In
the past, Linenberg has been a principal shareholder of the Company and served
as a director of the Company.

         On March 14, 2000, the Company announced the sale of the business
conducted by Monitek and Monitek GmbH to Metrisa, Inc. ("MTRE") of Bedford,
Massachusetts. Under terms of the sale, the Company will sell substantially all
of its Monitek and Monitek GmbH assets to Metrisa for cash, notes, the
assumption of selected liabilities, and Metrisa stock. The consideration
received upon the sale of the assets will not be sufficient to pay any dividends
or distributions to the shareholders. Sentex intends to use the consideration
received in the transaction to satisfy existing liabilities and, if available,
purchase additional assets in other lines of business, which at this time have
not been determined. Metrisa makes scientific and process control equipment for
markets worldwide. Metrisa's sales in fiscal 1999 were $8 million, compared to
$4.1 million for Monitek.

DESCRIPTION OF BUSINESSES OF MONITEK

         General

         Monitek designs, develops, assembles and markets instruments for the
measurement of clarity (turbidity), suspended solids content, color and purity
of liquids in industrial and waste water environments. Monitek's products are
typically used in-line (i.e., inserted directly into the monitored liquid),
thereby facilitating automation and control of various industrial processes by
providing on-line (i.e., continuous) measurement of the characteristic being
monitored. Monitek's current line of products, which are based on optical and
acoustic technologies, have been specially adapted for various applications in
the chemical and petrochemical, water treatment, food and beverage, pulp and
paper, and biotechnology and pharmaceutical industries, where their abilities to
withstand high temperature,

                                      -3-
<PAGE>   4

extremes in pressure and corrosive environments are important factors. The
Company believes Monitek's instruments are capable of adaptation and enhancement
for use in other industries, as well as for additional applications in those
industries which Monitek currently serves. Monitek's products are currently sold
worldwide.

         Existing Products

         Monitek's products consist of optical based products, acoustic based
products and spare parts.
         (i) Optical Based Products. The heart of Monitek's product line are
suspended solids analyzers, which are in-line monitors that measure clarity,
suspended solids content and purity of liquids. Monitek's two major types of
suspended solids analyzers, which operate on the same basic principle, are
turbidimeters and concentration/content monitors. The suspended solids analyzers
work on the principle of light scatter and/or absorption. Light is emitted by
the instrument and photosensors detect the amount of light that is either
scattered or absorbed by the solids in the liquid. This information is
transmitted to a remote electronic indicating transmitter device, which displays
the data on a scale of the characteristic being monitored and retransmits the
information to a control computer or data logger. Many of Monitek's transmitters
offer alarm features while others eliminate false readings caused by bubbles or
signal an abnormal sample. The sales prices of suspended solids analyzers range
from $4,000 to $10,000 per system.

         Monitek's suspended solids analyzers are available in a wide range of
sizes and configurations to meet customer requirements. Monitek's basic
instruments can also be specially adapted for particular applications with the
addition of available options. Certain instruments are designed to be "explosion
proof," (i.e., the instrument is enclosed in such a way as to prevent internal
electrical or chemical reactions from igniting explosive mixtures existing in
the atmosphere surrounding the encased instrument, and have been approved for
the use in explosive environments by Underwriters' Laboratories (U.L.)). This
characteristic is of a particular importance in the petrochemical industry.
Other instruments are adapted to be watertight and dust-tight to protect the
equipment against splashing, seeping or falling water and severe external
condensation, while others are adapted to withstand high temperatures, extremes
in pressure and corrosion for applications in such industries as the chemical
and pulp and paper industries.

         Monitek has developed a number of insertable in-line sensors for
measurement of turbidity and consistency, for use in various industries. One of
the sensors is called the Cell Density Analyzer, for measurement of cell growth
rate and concentration in fermentation processes. Fermentation is a major
process used in the pharmaceutical and biotechnology industries and the
instrument provides a continuous measurement relative to cell growth. Unlike
Monitek's original line of suspended solids analyzers, which require accessories
fitted to the actual pipe size to which the instrument is attached, the
insertable sensors are capable of being inserted into any size pipe through
special fittings. The advantage of such devices over conventional suspended
solids analyzers is their ability to provide the customer with an easier, more
cost-effective means of installation and servicing, in that it does not require
shutting down the process flow of the liquid or extensive structural work often
necessary with the non-insertable products.

         A second optical-based product line is color monitors, which are used
to measure the difference in the absorption of light through a liquid at two
wavelengths. This measurement is indicative of color or concentration. To date,
these instruments have been sold primarily to petrochemical refineries where the
avoidance of color in the final product is essential. Monitek's color monitors
also have application in the processes of color addition and color removal in
such industrial liquids as printing inks, sugar, vegetable oil, beverages and
solvents. Color monitors use photosensors and optical filters that detect the
amount of light absorbed by the pertinent wavelength or color. Sales prices of
color monitors range from $6,000 to $14,000 per system.

         (ii) Acoustic Based Products. Monitek currently markets the Micro Pure
ultrasonic suspended solids meter, which has allowed Monitek to expand into new
markets and improve its effectiveness in existing markets. The acoustic
technique allows the low range measurement of suspended solids and emulsions
independent of color and coating. Significant opportunities exist for measuring
oil in water, inks, dyes and photographic liquids, all of which have been
difficult measurements for Monitek's optical products because of the lack of
light and/or existence of substances (i.e., oil) which coat the optical parts.
Micro Pure products range in price from $10,000 to $16,000 per system.

                                      -4-
<PAGE>   5

         (iii) Spare Parts. Sales of spare parts is an important part of
Monitek's business, accounting for approximately 15% of sales volume of Monitek
for the past three years.

Products Under Development

         Research and development activities of Monitek are primarily devoted to
the development of new products and the adaptation and enhancement of existing
products for new applications. The Company plans to make available a number of
new products and enhancements of existing Monitek products during fiscal 2000.

         Research and Development

         Monitek expended approximately $178,000 and $218,000 for research and
development during the fiscal years ended November 30, 1999 ("fiscal 1999") and
November 30, 1998 (the "fiscal 1998"), respectively. During fiscal 1999, a
number of products were improved and two new products were released for
production. The first new product was a forward scatter insertion sensor
("InVision" Turbidity System) for use in low range suspended solids applications
and the second was a micro-processor based transmitter designed to operate with
the InVision sensor and with Monitek's other turbidity sensors.

         Marketing, Distribution and Sales

         Monitek markets its products on a world-wide basis, with particular
emphasis on the United States and Continental Europe. Monitek employs two sales
managers, who oversee and monitor approximately 50 independent sales
representatives worldwide, with about half of such representatives selling in
the United States and the other half selling internationally.

         Manufacturing/Suppliers

         Monitek's manufacturing operations primarily involve the assembly,
testing, quality control and packaging of materials and components, which are
generally available in the market place from numerous suppliers and sources.
Material and components necessary for Monitek's manufacturing activities have
always been available, and Monitek does not anticipate any future shortages or
unavailability of such materials and components.

         Monitek's inventory is comprised primarily of parts to make
sub-assemblies, fully assembled instruments and materials required to adapt
instruments for particular applications and customer specifications. Monitek
attempts to maintain a sufficient inventory of materials and components it may
fill orders for its products within four to eight weeks after receipt of an
order.

         Warranties and Disclaimers

         Monitek typically warrants its products for a period of one year after
shipment and passes along any warranties from original manufacturers of
components used in its products. To date, Monitek has not had any significant
claims pursuant to warranties. Monitek provides for its own equipment servicing
for certain products with in-house and field service personnel.

         Competition

         Monitek sells products which have use in a wide variety of applications
in many industrial and municipal markets. Monitek faces competition in each
market to which it sells products from companies which sell products that are
substantially similar to, or which perform comparable functions as, those sold
by Monitek. McNabb, Wedgewood Technologies, Optek, BTG, Hach and Sigrist are
Monitek's principle competitors which sell products using the same or similar
technologies as those of Monitek. Valmet Automation Inc., Royce Instruments and


                                      -5-
<PAGE>   6

Kay-Ray Inc. sell devices based on mechanical, ultrasound and nuclear
technologies which compete with certain of the products sold by Monitek. Certain
of Monitek's competitors have production facilities in Europe and consequently
may not be subject to the same fluctuations in the value of the United States
dollar as Monitek is with respect to its German subsidiary. All of such
companies, and many smaller entities that specialize in a limited number of
products competitive with those of Monitek, have financial, marketing and other
resources substantially greater than those of Monitek.

         Monitek believes that the most significant competitive factors with
respect to the industrial market are technical performance and adaptability,
quality, maintenance and service, while price is the major competitive factor
for the municipal market. Monitek believes it has a competitive advantage in its
ability to service numerous market segments while other companies, other than
Optek, service only a limited market. Accordingly, a salesperson or distributor
calling on an industrial company which has a liquid-based product or uses water
in its manufacturing process will generally have a number of Monitek's products
in its line which it could sell.

         Patents, Trademarks and Trade Secrets

         Monitek has obtained 11 United States patents and a number of foreign
patents covering fundamental technology and applications of use of the Micro
Pure product line and some other potential products.

         Monitek believes that trade secrets and unpatented proprietary
knowledge used to adapt its products for specific industries and applications is
of greater importance to the development of its competitive position than
patents. All of Monitek's employees have entered into confidentiality agreements
and have agreed to assign to Monitek any inventions relating to Monitek's
business made by them while in Monitek's employ. However, there can be no
assurance that others may not acquire or independently develop similar
technologies which will enable them to more effectively compete with Monitek.

         While Monitek believes that none of its instruments infringes upon
patents or other proprietary rights of others, there is a possibility that other
parties may claim that parts of Monitek's instruments do infringe upon their
patents or other proprietary rights. There can be no assurance that Monitek will
be successful in defending against such claims of infringement, and the expenses
of defending such claims could be substantial.

         Monitek has obtained registered trademarks for the names "Monitek" and
"Micro Pure" and the Monitek and Micro Pure logos.

         Employees

         As of February 29, 2000, the Company employed a total of 15 full-time
staff, 2 of whom were engaged in product design and engineering, 7 were engaged
in manufacturing and production, 4 were engaged in marketing and sales and 2
were engaged in general corporate and administrative positions. The Company also
had 4 part-time employees and 1 temporary employee. The Company's ability to
develop, manufacture, market and sell products and to establish and maintain its
competitive position will depend, in large part, on its ability to attract and
retain qualified personnel. None of the Company's employees is represented by a
union. The Company believes that its relations with its employees are
satisfactory.

         Government Regulations

         The Company complies with a number of government regulations, including
environmental regulations. The cost of such compliance is not significant. The
Company has routinely received all governmental approvals necessary to conduct
its business.

ITEM 2    PROPERTIES

         Monitek's manufacturing operations occupy approximately 3,000 square
feet of leased space in Livermore, California. In addition, Monitek conducts
corporate accounting, sales and research and development functions in
California. The lease provides for a base annual rental of approximately $35,000
and expires in November 2000.

         Monitek also leases approximately 6,000 square feet of office and
warehouse space in Dusseldorf, Germany pursuant to a lease that expires in
October 2001, and provides for a base annual rental of $80,000, based on the
rate of exchange in effect at November 30, 1999.

         The Company believes that these facilities are adequate to provide for
the Company's business needs during the remaining terms of the respective
leases.


ITEM 3 LEGAL PROCEEDINGS

         A former manufacturers' representative has filed a lawsuit against
Monitek GmbH, captioned Foerster vs Monitek GmbH, in the District Court in
Duesseldorf, Germany, claiming unlawful termination of his contract with the
Company and asking for compensation under a German law protecting
representatives of long standing. The suit asks for a total of $117,000, based
on the currency exchange rate as of November 30, 1999. The Company's enclosed
balance sheet includes an accrual of $51,000 based on an estimate of exposure
provided by the Company's German council.

ITEM 6 MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
       OF OPERATIONS

CAUTIONARY STATEMENT FOR PURPOSES OF THE "SAFE HARBOUR" OF THE PRIVATE
SECURITIES LITIGATION REFORM ACT OF 1995.

         Certain statements in the Management's Discussion and Analysis of
Financial Condition and Results of Operations and the Financial Statements
included in this Annual Report on Form 10-KSB, in the Company's press releases
and in oral statements made by or with the approval of an authorized executive
officer of the Company constitute "forward-looking statements" as that term is
defined under the Private Securities Litigation Reform Act of 1995. These may
include statements projecting, forecasting or estimating Company performance and
industry trends. The achievement of the projections, forecasts or estimates is
subject to certain risks and uncertainties. Actual results and events may differ
materially from those projected, forecasted or estimated. The applicable risks
and uncertainties include general economic and industry conditions that affect
all businesses, as well as matters that are specific to the Company and the
markets it serves.

         General risks that may impact the achievement of such forecasts include
compliance with new laws and regulations; significant raw material price
fluctuations; currency exchange rate fluctuations; business cycles; and
political uncertainties. Specific risks to the Company include an inability of
the Company to finance its working capital needs; an inability of the Company to
successfully integrate the business of Sentex and Monitek; a risk of recession
in the economies in which its products are sold, such as the Chemical or
Petroleum industries; and new or emerging products from current competitors. In
light of these and other uncertainties, the inclusion of a forward-looking
statement herein should not be regarded as a representation by the Company that
the Company's plans and objectives will be achieved.

FINANCIAL CONDITION

Working Capital and Liquidity

         During the last several fiscal years, the Company has incurred losses
from operations. In addition, the Company's certified public accountants,
Hausser+Taylor LLP, have included in their auditors' report, which covers the
Company's financial statements for the years ended November 30, 1997 and
November 30, 1998, a statement that the Company's recurring losses from
operations raised substantial doubt about the Company's ability to continue as a
going concern. Subsequently, for fiscal 1999, the Company has sustained losses
of approximately $1,440,000. These losses have had a substantial adverse effect
on the working capital of the Company.

         Working capital decreased to negative $3,219,000 at November 30, 1999
as compared to negative $1,823,000 as of November 30, 1998. The decrease is
mainly due to the losses sustained by the Company during fiscal 1999. Cash and
cash equivalents equaled approximately $15,000 as of November 30, 1999 as
compared to $111,000 at November 30, 1998. As set forth in the accompanying
independent auditors' report and notes to consolidated financial statements, the
Company's recurring losses from operations and the resulting effect on cash flow
have reduced the Company's liquidity to its current level, which raises
substantial doubt about the Company's ability to continue as a going concern.

         To address the Company's working capital needs, the Company, in July
1998, established a bank line of credit of $2,000,000, which was fully drawn on
as of November 30, 1999. This line of credit is secured by the personal
guarantee of Robert S. Kendall, the Chairman of the Company. From time to time,
CPS has provided the Company with temporary working capital loans and, as of
November 30, 1999, there was an outstanding borrowing of $1,705,000 on such
loans. As a result of the acquisition of Cypress, the Company became obligated
to make payments to the shareholders of Cypress (for payment of shares and
performing future consulting services) of approximately $535,000 over the next
four fiscal years. As of November 30, 1999, payments of $236,000 had been made
to the Cypress shareholders.

         Without continued financial support from CPS or Mr. Kendall, the
Company would not generate sufficient cash in the next 12 months to meet its
working capital needs.

Net Operating Losses; IC-DISC

         The Company has approximately $11,695,000 in net operating losses as of
fiscal 1999, which will expire at various dates through the year 2018 that are
mainly attributable to losses incurred by Monitek. Federal tax law imposes
restrictions on the use of net operating loss carry-forwards in the event of a
change in ownership, such as a merger. Due to the Merger, approximately
$6,265,000 of the $11,695,000 net operating losses may be subject to these
limitations and potentially may not be able to provide any economic benefit to
the Company.

         As of April 1, 1991, Monitek's IC-DISC, Monitek International, Inc.,
was effectively terminated. As a result, Monitek had begun repatriation of the
undistributed earnings of the IC-DISC as of April 1, 1991. The undistributed
earnings of approximately $780,000 has been and will continue to be recognized
as income, for tax return purposes, over the 10-year period ending March 31,
2001.

RESULTS FROM OPERATIONS

         Fiscal 1999 as Compared to Fiscal 1998

         The Company's net sales decreased by 26%, from $5,590,000 for fiscal
1998 to $4,115,000 for fiscal 1999. Sales of Systems products decreased to zero
for the Fiscal 1999 compared to $344,000 for Fiscal 1998, as a result of the
sale of Systems to ALR. Monitek's domestic sales decreased by $437,000, or 27%,
while export sales from the United States decreased by $23,000, or 5%. Sales to
Continental Europe by Monitek GmbH decreased by $671,000, or 22%, from fiscal
1998 to fiscal 1999. The Company's management believes that the primary cause of
these sales reductions was uncertainty on the part of customers and
manufacturers' representatives regarding the strategic direction of the Company.

         Cost of goods sold, as a percentage of sales, increased to 54% for
fiscal 1999 from 50% for fiscal 1998 , primarily as a result of the decrease in
sales without a corresponding reduction in direct labor and factory overhead and
an increase in inventory obsolescence reserves. Direct labor and overhead
increased to 15% of net sales for fiscal 1999 from 13% for fiscal 1998. During
fiscal 1999, the Company increased its reserve for obsolescence by $86,000, or
2% of net sales.

         Selling, general and administrative expenses decreased to $3,155,000
for fiscal 1999 from $4,494,000 for fiscal 1998. The sale of Systems, which had
total expenses of $592,000 during fiscal 1998, accounted for a large percentage
of the total reduction. Cost reduction measures, which were implemented by
management during fiscal 1998 and fiscal 1999, resulted in a decrease of
approximately $540,000 for fiscal 1999 as compared to fiscal 1998. Sales
commissions decreased to $806,000 from $1,009,000 as a direct result of the
decrease in net sales.

         Research and development expenses decreased to $178,000 for fiscal 1999
from $218,000 for fiscal 1998, primarily as a result of a decrease in activities
by outside consultants.

         Interest and other income decreased to $18,000 for fiscal 1999 from
$130,000 for fiscal 1998, primarily as a result of average cash balances
maintained for the two fiscal years.

         During fiscal 1998, the Company experienced a one-time $423,000 loss on
disposal of assets as a result of the sale of Systems.

         Net losses decreased to $1,440,000 for fiscal 1999 from $2,205,000 for
fiscal 1998, primarily as a result of the reduction in selling, general and
administrative expenses, the reduction in research and development expenses and
the



                                      -10-
<PAGE>   11

sale of Systems to ALR, partially offset by the decrease in sales, the increase
in cost of sales as a percentage of net sales and the decrease in interest and
other income.


CHANGES IN ACCOUNTING STANDARDS

         In June 1997, SFAS No. 131, Disclosures About Segments of an Enterprise
and Related Information, was issued. SFAS No. 131 changes the standards for
reporting financial results by operating segments, related products and
services, geographic areas and major customers. The Company must adopt the new
standard no later that November 30, 1999.

         In June 1998, SFAS 133, Accounting for Derivative Instruments and
Hedging Activities, was issued. SFAS 133 establishes accounting and reporting
standards for derivative instruments and hedging activities. SFAS 133 is
effective for fiscal years beginning after June 15, 1998. Management believes
this pronouncement will have no effect on the financial statements.

shareholders held on November 14, 1996. (See Item 4). Under the Plan, the
Company may grant different types of options covering up to 7,000,000 Common
Shares to its existing and future directors, officers and employees. As of

                  with respect to such shares. CPS beneficially owns 6,389,204
                  Common Shares, which were purchased from Linenberg in April
                  1998, but have not yet been transferred to CPS by the transfer
                  agent. CPS also beneficially owns 21,595,149 Common Shares
                  which have not been issued by the transfer agent. CPS received
                  5,025,745 Common Shares in lieu of accrued management fees and
                  16,569,404 Common Shares which were purchased from a prior
                  owner of Sentex Common Shares.

*Represents less than 1% of the outstanding Common Shares.

SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING REQUIREMENTS

         As required under the securities laws of the United States, the
Company's directors, its executive (and certain other) officers, and any persons
holding ten percent or more of the Common Shares must report on their ownership
of the Common Shares and any changes in that ownership to the Securities and
Exchange Commission and to the National Association of Securities Dealers,
Inc.'s Automated Quotation System. Specific due dates for these reports have
been established. During the year ended November 30, 1999, Mr. Kendall purchased
an additional 10,000 Common Shares and he inadvertently failed to report this
transaction on Form 4.

ITEM 12 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

         CPS Management Agreement. After CPS acquired effective control of the
Company, CPS entered into a Management Agreement with the Company, which was
effective on March 1, 1996 (the "Original Management Agreement"). In connection
with the execution of the Merger Agreement, CPS and the Company entered into an
Amended and Restated Management Agreement (the "Amended and Restated Management
Agreement"). Pursuant to the Original Management Agreement, CPS agreed to cause
its personnel to perform the functions that would normally be performed by the
officers of the Company. Presently, such personnel consists mainly of Mr.
Kendall, the Chairman of CPS and Peggy Nutaitis, the Secretary of CPS. In order
to permit Mr. Kendall and Ms. Nutaitis to function as officers and for them to
be properly insured as officers of the Company, Mr. Kendall has been elected as
the President and Treasurer of the Company and Ms. Nutaitis has been elected
Secretary of the Company.

         Under the terms of the Original Management Agreement, CPS received an
annual fee of $193,800, which was payable monthly. Under the terms of the
Amended and Restated Management Agreement, the annual fee was increased to
$393,800 to account for the increase in tasks and responsibilities relating to
the operation of Monitek. Due to the present financial condition of the Company,
CPS has not received payment under the Amended and Restated Agreement since May
1997, but the Company has accrued such expense. On May 15, 1998, CPS and the
Company entered into the Second Amended and Restated Management Services
Agreement, pursuant to which CPS agreed to accept 5,025,745 Common Shares in
lieu of accrued management fees equaling $196,900, representing fees for the
second half of fiscal 1997. All the shares acquired by CPS were acquired for
investment purposes.

         In December 1997, CPS and the Company agreed to a reduced management
fee of $250,000 for fiscal 1998 and in December 1998, the parties agreed to
reduce the fee to $200,000 for fiscal 1999 and subsequent years. CPS and the
Company have agreed that the balance due as of November 30, 1999, which totals
$325,000, and the fee for fiscal 2000, will be paid at some future time when the
financial condition of the Company improves.

         Working Capital Assistance. During fiscal 1997 through fiscal 1999, CPS
and Mr. Kendall provided the Company assistance in connection with funding its
working capital needs in the form of loans and security for bank loans. From May
1997 through November 1999, CPS provided the Company a series of temporary
working capital loans at a prime rate at National City Bank, Cleveland, Ohio
("NCB"). The outstanding balance of such loans totaled $1,705,232, including
accrued interest, as of November 30, 1999. From time to time Mr. Kendall has
also provided security to banks by permitting the banks to obtain a security
interest in Mr. Kendall's personal



                                      -15-
<PAGE>   16

assets and/or providing guarantees so the Company could obtain financing from
the bank. Except for the interest to be received on the loans provided by CPS,
neither Mr. Kendall nor CPS has received nor will receive any remuneration in
connection with providing such working capital assistance to the Company unless
the notes are converted into Common Shares at some future date. The Company
believes the interest payable to CPS is and was on terms no less favorable than
could be obtained pursuant to an arms-length transaction.

                          Independent Auditors' Report
                          ----------------------------


To the Board of Directors and Stockholders
Sentex Sensing Technology, Inc.
Cleveland, Ohio


         We have audited the accompanying consolidated balance sheet of Sentex
Sensing Technology, Inc. and subsidiaries as of November 30, 1999, and the
related consolidated statements of operations, stockholders' equity, and cash
flows for each of the two years in the period ended November 30, 1999. These
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

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

         In our opinion, the financial statements referred to above present
fairly, in all material respects, the consolidated financial position of Sentex
Sensing Technology, Inc. and subsidiaries as of November 30, 1999, and the
consolidated results of their operations and their cash flows for each of the
two years in the period ended November 30, 1999, in conformity with generally
accepted accounting principles.

         The accompanying financial statements have been prepared assuming that
the Company will continue as a going concern. As discussed in Note 2A to the
financial statements, the Company has in the past and continues to sustain
substantial net and operating losses. In addition, the Company has used
substantial amounts of working capital in its operations which has reduced the
Company's liquidity to a very low level. Additionally, the Company's stock is no
longer listed on the NASDAQ Small Cap Market tier of the NASDAQ stock market and
is now traded on the Over-the-Counter Bulletin Board which might limit the
Company's ability to raise equity capital. These matters raise substantial doubt
about the Company's ability to continue as a going concern. The financial
statements do not include any adjustments relating to the recoverability and
classification of recorded assets or the amounts and classification of
liabilities that might be necessary in the event the Company cannot continue in
existence.

                SENTEX SENSING TECHNOLOGY, INC. AND SUBSIDIARIES

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1.  ORGANIZATION, BACKGROUND AND INDUSTRY SEGMENT

         The consolidated financial statements include the accounts of Sentex
         Sensing Technology, Inc. and its wholly-owned subsidiaries (the
         "Company"). All material intercompany accounts and transactions have
         been eliminated in consolidation.

         The Company's business is confined to a single industry segment,
         manufacturing analysis equipment. One of the subsidiaries, Sentex
         Systems, Inc., whose assets and operations were disposed of in the year
         ended November 30, 1998, was engaged in the business of developing,
         manufacturing and selling automated gas chromatography devices designed
         to detect the presence of certain substances by identifying and
         measuring the concentrations of certain atmospheric vapors (see Note
         14). Monitek Technologies, Inc. ("Monitek") was acquired by the Company
         on November 30, 1996 and designs, develops, assembles and markets
         instruments for the measurement of clarity (turbidity), suspended solid
         content, color, purity, flow, level and volume of liquids in industrial
         waste water environments. Monitek GmbH, a wholly-owned subsidiary of
         Monitek, was formed in Germany to sell and service Monitek's products
         throughout Continental Europe. At November 30, 1999, Monitek GmbH's
         assets, located in Continental Europe, represent approximately 41% of
         the Company's total consolidated assets. A new subsidiary, Cypress
         Instruments, Inc. ("Cypress"), was acquired by the Company on March 5,
         1998 for the purpose of acquiring a new product line that was currently
         under development. The products under development are similar to those
         of Monitek and have been folded into their existing product lines.

NOTE 2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

         A.       Going Concern - The accompanying financial statements have
                  been prepared in conformity with generally accepted accounting
                  principles, which contemplate continuation of the Company as a
                  going concern. However, the Company has in the past and
                  continues to sustain substantial net and operating losses. In
                  addition, the Company has used substantial amounts of working
                  capital in its operations which has reduced the Company's
                  liquidity to a very low level. Additionally, the Company's
                  stock is no longer listed on the NASDAQ Small Cap Market tier
                  of the NASDAQ stock market and is now traded on the
                  Over-the-Counter Bulletin Board which might limit the
                  Company's ability to raise equity capital. These matters raise
                  substantial doubt about the Company's ability to continue as a
                  going concern. The financial statements do not include any
                  adjustments relating to the recoverability and classification
                  of recorded assets or the amounts and classification of
                  liabilities that might be necessary in the event the Company
                  cannot continue in existence. The Company's ability to
                  continue in existence is primarily dependent upon its ability
                  to arrange adequate financing and to attain satisfactory
                  levels of operating cash flows.

         B.       Inventories - Inventories are stated at the lower of cost
                  (determined by the first-in, first-out method) or market.

                SENTEX SENSING TECHNOLOGY, INC. AND SUBSIDIARIES

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

NOTE 2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

         C.       Property and Equipment - Property and equipment are stated at
                  cost less accumulated depreciation and amortization.
                  Depreciation and amortization are computed using straight-line
                  and accelerated methods over the estimated useful lives of the
                  respective assets.

                  When assets are retired or otherwise disposed of, the cost and
                  related accumulated depreciation or amortization are removed
                  from the accounts and any resulting gain or loss is recognized
                  in income or loss for the period. The cost of maintenance and
                  repairs is included in the statements of operations as
                  incurred; significant renewals and betterments are
                  capitalized.

         D.       Revenue Recognition - The Company records revenue as products
                  are shipped to customers.

         E.       Research and Development Costs - Research and development
                  costs are expensed as incurred.

         F.       Cash and Cash Equivalents - Cash equivalents are comprised of
                  certain highly liquid investments with a maturity of three
                  months or less when purchased.

         G.       Concentration of Credit and Risk Factors - Financial
                  instruments which potentially subject the Company to
                  concentrations of credit risk are cash and equivalents,
                  investments in certificates of deposit and accounts receivable
                  arising from its normal business activities. Concentrations of
                  credit risk with respect to trade receivables are limited, due
                  to the number of customers comprising the Company's customer
                  base and their disposition across different industries and
                  geographic areas. Bad debt expenses have not been material.
                  The Company places its cash and cash equivalents with high
                  credit quality financial institutions. The amount on deposit
                  in any one institution that exceeds federally insured limits
                  is subject to credit risk.

                  The Company operates in an environment with many financial
                  risks, including, but not limited to, its lack of history of
                  profitable operations, the inherent risks associated with new
                  product research and development, the highly competitive
                  nature of the industry in which it operates and worldwide
                  economic conditions. The Company's ability to capitalize on
                  its current and emerging technology and diversity of its
                  operations and products is also dependent upon the Company's
                  ability to obtain the necessary capital through operating cash
                  flow, additional borrowings or additional equity funds.

         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.

NOTE 2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

         I.       Income Taxes - The Company utilizes Statement of Financial
                  Accounting Standards No. 109 ("SFAS 109"), Accounting for
                  Income Taxes, which requires an asset and liability approach
                  to financial accounting and reporting for income taxes. The
                  difference between the financial statement and tax basis of
                  assets and liabilities is determined annually. Deferred income
                  tax assets and liabilities are computed for those temporary
                  differences that have future tax consequences using the
                  current enacted tax laws and rates that apply to the periods
                  in which they are expected to affect taxable income. Valuation
                  allowances are established, if necessary, to reduce the
                  deferred tax asset to the amount that will, more likely than
                  not, be realized. Income tax expense is the current tax
                  payable or refundable for the period plus or minus the net
                  change in the deferred tax assets and liabilities.

                  The Company has no current plans to repatriate undistributed
                  earnings of Monitek's foreign subsidiary. Therefore, no tax
                  has been provided to cover the repatriation of such
                  undistributed earnings. The cumulative amount of undistributed
                  earnings for which the Company has not provided United States
                  income taxes is not material.

                  The Company has terminated its IC-DISC and, therefore, has
                  begun repatriation of the undistributed earnings of the
                  IC-DISC. The undistributed earnings of approximately $780,000
                  are recognized as income by the Company over a 10-year period
                  ending March 31, 2001.

         J.       Fair Value of Financial Instruments - The fair values of cash,
                  accounts receivable, accounts payable and other short-term
                  obligations approximate their carrying values because of the
                  short maturity of these financial instruments. The carrying
                  values of the Company's long-term obligations approximate
                  their fair value. In accordance with Statement of Financial
                  Accounting Standards No. 107, Disclosure About Fair Value of
                  Financial Instruments, rates available at balance sheet dates
                  to the Company are used to estimate the fair value of existing
                  debt.

         K.       Foreign Currency Translation - The Company accounts for
                  foreign currency translation in accordance with Statement of
                  Financial Accounting Standards No. 52, Foreign Currency
                  Translation. The functional currency of the Company's German
                  subsidiary is the deutsche mark. All transactions of that
                  subsidiary denominated in currency other than the functional
                  currency are remeasured into the functional currency with the
                  resulting gain or loss included as foreign currency
                  transaction gains or losses in the accompanying consolidated
                  statements of operations. Assets and liabilities denominated
                  in currencies other than U.S. dollars are translated at year
                  end exchange rates and all statement of operations items are
                  translated at the weighted average exchange rate for the year.

         L.       Loss Per Share - Loss per share is calculated using the
                  weighted average number of shares outstanding.

NOTE 2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

         M.       New Authoritative Pronouncements - In June 1997, SFAS No. 131,
                  Disclosures About Segments of an Enterprise and Related
                  Information, was issued. SFAS No. 131 changes the standards
                  for reporting financial results by operating segments, related
                  products and services, geographic areas and major customers.
                  The Company adopted the new standard, which did not materially
                  affect the Company's financial statements.

                  In June 1998, SFAS 133, Accounting for Derivative Instruments
                  and Hedging Activities, was issued. SFAS 133 establishes
                  accounting and reporting standards for derivative instruments
                  and hedging activities. SFAS 133 is effective for fiscal years
                  beginning after June 15, 2000. Management believes this
                  pronouncement will have no effect on the financial statements.

NOTE 3.  ACQUISITIONS

         In March 1998, the Company acquired 100% of the outstanding stock of
         Cypress Instruments, Inc. ("Cypress") for the purpose of acquiring a
         new product line that was under development. The acquisition was not
         material to the overall business of the Company and was accounted for
         as a purchase. Consideration in the amount of $150,000 was given in the
         form of a contingent payment. The excess of the aggregate purchase
         price over the estimated fair value of the net assets acquired
         (goodwill) was $150,000, and is being amortized over 20 years. In
         connection with the acquisition, the Company entered into consulting
         agreements with the former shareholders of Cypress (see Note 9).

         On November 30, 1996, the Company acquired 100% of the outstanding
         stock of Monitek Technologies, Inc. (see Note 1). The acquisition was
         accounted for as a purchase and resulted in the issuance of 11,659,681
         common shares and convertible notes having face and discounted values
         of $622,000 and $468,000, respectively, in exchange for 100% of the
         outstanding stock and other securities of Monitek. The acquisition cost
         attributable to the common shares of $348,000 was based on the
         estimated fair value, including goodwill, of the net assets acquired,
         net of the cost attributable to the convertible notes and before costs
         associated with the registration of the securities issued ($150,000,
         which was charged against stockholders' equity). In addition, the total
         acquisition cost includes direct acquisition costs of $72,319. The
         estimated fair market value of tangible assets and liabilities acquired
         was $2,650,153 and $2,013,236, respectively. The excess of the
         aggregate purchase price over the estimated fair market value of the
         net assets acquired (goodwill) was approximately $251,402, which is
         being amortized on a straight-line basis over 20 years.

NOTE 7.  NOTES PAYABLE - BANK AND OTHER BORROWING ARRANGEMENTS

         The Company has available a $2,000,000 demand line of credit secured by
         the Company's assets and the assets of the Company's Chairman of the
         Board. Interest is charged on a 90 day contract period at the lower of
         the prime lending rate or LIBOR plus 150 basis points (8.75% as of
         November 30, 1999). Interest is payable monthly. Amounts outstanding
         under the line amounted to $2,000,000 at November 30, 1999.

         During the years ended November 30, 1999 and 1998, a principal
         shareholder and the Company's Chairman provided the Company assistance
         in connection with funding its working capital needs in the form of
         loans and security for bank loans. As of November 30, 1999, the Company
         had notes payable of $1,705,232 (bearing interest at the prime rate) to
         its principal shareholder, CPS Capital, Ltd., in connection with such
         unsecured loans.

         Interest expense for the years ended November 30, 1999 and 1998
         amounted to $228,525 and $182,372, respectively.

NOTE 8.  CONVERTIBLE SUBORDINATED NOTES PAYABLE

         In connection with the acquisition of Monitek on November 30, 1996, the
         Company issued convertible notes having aggregate face and discounted
         values of $622,000 and $468,000, respectively. The unsecured notes,
         which are subordinated to all present and future obligations of the
         Company, have a stated interest rate of 5.05% per annum and were
         discounted using a yield rate of 15% to reflect management's estimate
         of the fair value of the debt.

         Interest on the notes is payable annually (November 30) in shares of
         the Company's common stock based on the average of the bid and ask
         prices of the shares on the last ten trading days prior to the date on
         which the interest payment is due. Interest expense related to the
         convertible subordinated notes payable amounted to approximately $1,562
         and $14,645 for the years ended November 30, 1999 and 1998,
         respectively. In 1998, the Company issued 1,118,467 shares of common
         stock in satisfaction of the accrued interest. The notes were
         convertible at various rates ($.0194 and $.0562 on $136,414 and
         $485,586 of face amount, respectively) averaging $.03 per face amount
         of debt, into an aggregate of 15,671,969 shares of the Company's common
         stock.

         The notes were convertible by the holder 300 days after the second
         anniversary of issuance and earlier under certain conditions including
         certain changes in control or the restructuring/recapitalization of the
         Company. The notes could be converted at the Company's option 345 days
         after the second anniversary of issuance into that number of shares by
         dividing the face amount of the note by $.075 or at a time earlier at
         the standard conversion rates ($.0194 and $.0562) if there is a proxy
         contest for control of the Company's Board of Directors or if the
         Company is unable, in the judgment of the Company's Board of Directors,
         without compelling such a conversion, to obtain the requisite
         shareholder vote to approve a material transaction approved by the
         Board of Directors. The conversion terms contain standard anti-dilutive
         provisions to adjust the conversion price. In the event the notes are
         not converted, they become due on November 30, 1999.

NOTE 8.  CONVERTIBLE SUBORDINATED NOTES PAYABLE (CONTINUED)

         In 1998, a board resolution was proposed to allow the holder of
         significantly all of the Company's convertible subordinated notes
         payable to convert its notes immediately without regard to restrictions
         thereon in the hopes of reducing the amount of the Company's debt. The
         holder agreed to convert the notes if CPS Capital, Ltd. ("CPS")
         purchased the common shares that would be held by the holder following
         conversion. CPS agreed to purchase the common shares (including shares
         issued in satisfaction of accrued interest) for approximately $230,000.
         Pursuant to the board resolution, convertible notes, having a face
         value of $609,578 and a carrying value of $529,690, were converted into
         15,450,937 shares of the Company's common stock. The remaining face and
         carrying values of the subordinated notes at November 30, 1999 amounted
         to $12,423 and $11,348, respectively.

NOTE 9.  CONSULTING CONTRACTS PAYABLE

         In connection with the purchase of Cypress (see Note 3), the Company
         entered into consulting agreements with the principal stockholders of
         Cypress. Payments under the agreements total $385,049 and are payable
         over thirty-six months. The Company has included the cost of the
         contracts in other assets and the payment requirements as a liability
         in its financial statements. The cost of contracts will be ratably
         expensed over the thirty-six month period of the contracts. As of
         November 30, 1999, the following is a schedule of future payment
         requirements:

2000      $128,350
2001       128,350

NOTE 10.     COMMITMENTS AND CONTINGENCIES

             The Company leases certain equipment and occupies premises under
             various operating leases. Rental expense amounted to approximately
             $315,000 and $272,000 (of which $-0- and $32,500 were for related
             party leases) for the years ended November 30, 1999 and 1998,

NOTE 11. STOCK INCENTIVE PLAN

         The Company has a long-term incentive plan ("Incentive Plan") to
         provide current and future directors, officers and employees incentives
         to stimulate their active interest in the development and financial
         success of the Company. The Incentive Plan provides for the granting of
         "incentive stock options," under Section 422 of the Internal Revenue
         Code of 1986, as amended, or other stock options, stock appreciation
         rights, restricted or nonrestricted stock awards to purchase not more
         than 7,000,000 shares (which shares have been reserved by the Company)
         of common stock as determined by the Company's Incentive Plan Committee
         (the "Committee"). The option prices per share of common stock, which
         is the subject of incentive stock options and other stock options under
         the Incentive Plan, shall not be less than 100% of the fair market
         value of the Company's shares of common stock on the date such option
         is granted. The Committee shall determine when each option is to expire
         but no option shall be exercisable for a period of more than 10 years
         from the date upon which the option is granted. Generally, options
         granted under the Incentive Plan vest or terminate upon the employee
         leaving the Company and are subject to automatic acceleration of any
         vesting requirements given certain changes in control of the Company.

         Stock appreciation rights may be awarded by the Committee at the time
         or subsequent to the time of the granting of options. Stock
         appreciation rights awarded shall provide that the option holder shall
         have the right to receive an amount equal to 100% of the excess, if
         any, of the fair market value of the shares of common stock covered by
         the option over the option price. Such amount shall be payable, as
         determined by the Committee, in one or more of the following manners:
         (a) cash; (b) fully-paid shares of common stock having a fair market
         value equal to such amount; or (c) a combination of cash and shares of
         common stock. As of November 30, 1999, the Company has not granted any
         awards under the Incentive Plan.

         Stock options outstanding at November 30, 1996 consisted of Monitek
         stock options that were automatically converted, at the date of
         acquisition (see Note 3), into options to purchase 2,583,110 of the
         Company's common shares at an average exercise price of $.1038 per
         share and a range of $.0725 to $.1812 per share. During the year ended
         November 30, 1997, 241,412 shares under option were forfeited and
         689,749 shares under option expired by their terms but were extended
         for an additional 18 months with an exercise price equal to the
         original exercise price of $.1812 per share (the fair value of the
         options under SFAS 123 was not material). During the years ended
         November 30, 1999 and 1998, 776,002 and 1,307,075 shares under option
         expired or were forfeited. Options outstanding to purchase the
         Company's stock at November 30, 1999 amounted to 258,621 shares at an

NOTE 13.     INCOME TAXES

         As referred to in Note 1, the Company utilizes SFAS 109, Accounting for
         Income Taxes. A reconciliation between the Company's effective income
         tax rate and the statutory federal income tax rate is as follows for
         the years ended November 30:

                                            1999     1998

         The tax effects of significant temporary differences that give rise to
         significant portions of the deferred tax assets and deferred tax
         liabilities are presented below for the years ended November 30:

                                          1999           1998
                                          ----           ----
Deferred tax assets:
 Allowance for doubtful accounts and
  miscellaneous other                 $   (17,600)   $   (24,200)
  Net operating loss carryforward       1,846,200      1,525,400

     Net deferred tax assets          $      --      $      --
                                      ===========    ===========


         The deferred tax assets do not include deferred tax assets related to
         purchased net operating loss carryforwards that are subject to usage
         limitations (see below).

         The Company established a valuation allowance against tax benefits that
         are potentially available to the Company but have not yet been
         recognized. This valuation allowance relates to the amount of net
         operating loss carryforwards in excess of existing net taxable
         temporary differences and to certain deductible temporary differences
         that may not reverse during periods in which the Company may generate
         net taxable income. During the years ended November 30, 1999 and 1998,
         the Company recorded increases of $327,400 and $591,000, respectively,
         in the valuation allowance primarily as a result of the net operating
         loss generated during the year.

NOTE 13.     INCOME TAXES (CONTINUED)

             At November 30, 1999, the Company had approximately $11,695,000 of
             net operating loss carryforwards available to offset future federal
             taxable income. The federal net operating loss carryforwards expire
             at various dates through 2019. Federal tax law imposes restrictions
             on the utilization of net operating loss carryforwards in the event
             of a change in ownership. The Company's net operating loss includes
             approximately $6,265,000 of loss carryforwards that are subject to
             limitations as a result of these provisions.

NOTE 14.     LOSS ON SALE OF ASSETS

             In September 1998, the Company divested itself of Sentex Systems,
             Inc.'s operation, which generated less than 15% of the Company's
             revenues, but a much more significant part of the Company's losses.
             The Company agreed to sell all of the outstanding capital stock of
             Sentex Systems, Inc. to a company which is principally owned by
             Amos Linenberg. Prior to the sale, Mr. Linenberg was the President
             of Sentex Systems, Inc. and an Executive Vice President of the
             Company. In the past, Mr. Linenberg has been a principal
             shareholder of the Company and served as a director of the Company.
             In consideration for all of the capital stock of Sentex Systems,
             Inc., Mr. Linenberg terminated his existing Employment Agreement as
             of June 30, 1998, which, from July 1, 1998 through February 28,
             2000, would have required payments to Mr. Linenberg of
             approximately $325,000. Except for approximately $20,000 in
             expenses, the Company paid all operating costs and expenses of
             Sentex Systems, Inc. through June 30, 1998 and the Buyer assumed
             all the costs and operating expenses of Sentex Systems, Inc. from
             July 1, 1998 through the closing. The Company incurred a $423,283
             loss, representing the disposal of the net assets of Sentex
             Systems, Inc.

NOTE 15.     RELATED PARTY TRANSACTIONS

             Effective March 1, 1996, the Company entered into a management
             agreement with an affiliate and significant shareholder, CPS
             Capital, Ltd., to perform management and executive services at an
             annual fee of $193,800, payable ratably each month, plus any
             reasonable "out-of-pocket" expenses. In June 1996, under the terms
             of the Amended and Restated Management Agreement, the annual fee
             was increased to $393,800 to account for the increase in tasks and
             responsibilities relating to the operation of Monitek. Due to the
             present financial condition of the Company, CPS has not received
             payment under the Amended and Restated Agreement since May 1997,
             but the Company has accrued such expense. On May 15, 1998, CPS and
             the Company entered into the Second Amended and Restated Management
             Services Agreement, pursuant to which CPS agreed to accept
             5,025,745 common shares in lieu of accrued management fees equaling
             $196,900, representing fees for the second half of fiscal 1997.

             In December 1997, CPS and the Company agreed to a reduced
             management fee of $250,000 for fiscal 1998 and, in December 1998,
             the parties agreed to reduce the fee to $200,000 for fiscal 1999.
             CPS and the Company have agreed that the balance due as of November
             30, 1998, which totals $125,000, and the fee for fiscal 1999
             ($200,000) will be paid at some future time when the financial
             condition of the Company improves.

NOTE 17.     SUBSEQUENT EVENT

             On March 14, 2000, the Company announced the sale of the business
             conducted by Monitek and Monitek GmbH to Metrisa, Inc. (MTRE) of
             Bedford, Massachusetts. Under terms of the sale, the Company will
             sell substantially all of its Monitek and Monitek GmbH assets to
             Metrisa for cash, notes, the assumption of selected liabilities,
             and Metrisa stock. The consideration received upon the sale of the
             assets will not be sufficient to pay any dividends or distributions
             to the shareholders. Sentex intends to use the consideration
             received in the transaction to satisfy existing liabilities and, if
             available, purchase additional assets in other lines of business,
             which at this time have not been determined. Metrisa makes
             scientific and process control equipment for markets worldwide.
