                SENTEX SENSING TECHNOLOGY, INC. AND SUBSIDIARIES
           MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                            AND RESULTS OF OPERATIONS



The Company formed two wholly owned subsidiaries, Sentex Systems, Inc.,
("Systems") and Sentex Acquisitions Corp. on May 31, 1991, to separate the
present operations of the Company into a subsidiary to continue the business of
designing, developing and marketing gas chromatographic devices, and a
subsidiary to develop and acquire new investment opportunities. On September 4,
1998, all of the outstanding capital stock of Systems was sold (see explanation
below under Financial Condition) and the Company is no longer in the gas
chromatography business.

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 Sentex Merger Corp., a Delaware corporation and wholly
owned subsidiary of the Company, with and into Monitek. Monitek is now being
operated 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 over 60%
of Monitek's total revenues.

Hereinafter the "Company" shall refer to Sentex Sensing Technology, Inc. and its
wholly owned subsidiary, Monitek.

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. Monitek's current
line of products, which are based on optical, acoustic, magnetic and ultrasonic
technologies, have been specially adapted for various applications in the
chemical and petrochemical, food and beverage, water treatment, pulp and paper,
and bio-technology and pharmaceutical industries, where their abilities to
withstand high temperature, extremes in pressure and corrosive environments are
important factors. Monitek's products are currently sold world-wide.

In March 1998, the Company purchased Cypress Instruments, Inc. ("Cypress") for
the purpose of acquiring a new product line that has subsequently been folded
into the Monitek product line. The acquisition was not material to the overall
business of the Company.

FINANCIAL CONDITION

Working capital decreased to a negative $2,228,000 at May 31, 1999, as compared
to a negative $1,823,000 as of November 30, 1998. The decrease in working
capital is primarily due to the losses sustained by the Company during the first
half of Fiscal 1998. Cash and cash equivalents equaled approximately $36,000 as
of May 31, 1999, compared with $111,000 as of November 30, 1998. As set forth in
the independent auditors' report and notes to consolidated financial statements
that accompanied the Company's Form 10-KSB for the fiscal year ended November
30, 1998, 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 immediate working capital needs, the Company has
established a bank line of credit of $2,000,000, which was fully drawn on as of
May 31, 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 May 31, 1999, there was
an outstanding borrowing of $889,000 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. An initial
payment of $150,000 was made to the Cypress shareholders in May 1999, and an
additional sum of approximately $96,000, of which $43,000 of such amounts is
currently past due, are payable in fiscal 1999.

To address the Company's working capital needs on a more long-term basis, the
Company will attempt to generate cash from internal operations of the Company.
To control the operating losses attributable to Systems, which totaled
approximately $700,000 during fiscal 1998, the Company sold Systems to ALR
Group, Incorporated ("ALR"). In addition, during the fourth quarter of fiscal
1998 and the first quarter of fiscal 1999, the Company's management has made
other significant reductions in operating expense. The Company estimates that
these measures will save the Company approximately $40,000 per month.

On September 4, 1998, the Company completed the sale of all of the outstanding
capital stock of Systems to 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.

In consideration for all of the capital stock of Systems, ALR caused Mr.
Linenberg to terminate 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 Systems through
June 30, 1998 and ALR assumed all the costs and operating expenses of Systems
from July 1, 1998 through the closing. The Company incurred a $447,327 loss,
representing the disposal of the net assets of Systems.

         MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
                         RESULTS OF OPERATIONS (CONT'D)



In connection with the sale of Systems to ALR, the Company retained Linenberg to
consult for the Company on an as needed basis. The consulting period began
effective July 1, 1998 and continued through December 31, 1998. Linenberg
received approximately $12,000 per month under this consulting arrangement.

Even after divesting itself of Systems and further reducing operating expenses,
however, there can be no assurance that the Company will generate a positive
cash flow for Fiscal 1999. The ultimate profitability of the Company depends, in
large part, on increasing the sales of Monitek products and continuing to reduce
expenses.

Net Operating Losses; IC-DISC

The Company has approximately $10,751,000 in net operating losses as of fiscal
1998, which will expire at various dates through the year 2012 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
$10,751,000 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 OF OPERATIONS

Six Months Ended May 31, 1999 Compared to Six Months Ended May 31, 1998

The Company's net sales decreased by 19%, from $2,975,000 for the six months
ended May 31, 1998 ("Fiscal 1998 Six Months") to $2,406,000 for the six months
ended May 31, 1999 ("Fiscal 1999 Six Months"). Sales of Systems' products
decreased to zero for the Fiscal 1999 Six Months compared to $292,000 for Fiscal
1998, as a result of the sale of Systems to ALR. Monitek's domestic sales
decreased by $63,000, or 7%, while export sales from the United States decreased
by $12,000, or 6%. Sales to Continental Europe by Monitek GmbH decreased by
$202,000, or 13%, from the Fiscal 1998 Six Months to the Fiscal 1999 Six Months,
primarily as a result of weakness in the European economy.

Cost of goods sold, as a percentage of sales, decreased to 50% for the Fiscal
1999 Six Months from 51% for the Fiscal 1998 Six Months, primarily as a result
of a change in product mix. Direct labor and overhead decreased to 13% of net
sales for the Fiscal 1999 Three Months from 14% for the comparable Fiscal 1998
period, while material costs remained constant at 37% of net sales.

Selling, general and administrative expenses decreased to $1,380,000 for the
Fiscal 1999 Six Months from $2,147,000 for the Fiscal 1998 Six Months. The sale
of Systems, which had total expenses of $413,000 during the Fiscal 1998 Six
Months, accounted for the majority of the total reduction. Cost reduction
measures, which were implemented by management during the second half of Fiscal
1998, resulted in a decrease of approximately $240,000 for the Fiscal 1999 Six
Months as compared to the Fiscal 1998 Six Months.

Research and development expenses decreased to $90,000 for the Fiscal 1999 Six
Months from $152,000 for the Fiscal 1998 Six Months, primarily as a result of a
decrease in activities by outside consultants.

Operating losses decreased to $275,000 for the Fiscal 1999 Six Months from
$844,000 for the Fiscal 1998 Six Months, primarily as a result of the reduction
in selling, general and administrative expenses, the reduction in research and
development expenses and the sale of Systems to ALR, partially offset by the
decrease in sales.

Foreign currency transactions between Monitek and its German subsidiary resulted
in losses of $60,000 for the Fiscal 1999 Six Months and $5,000 for the Fiscal
1998 Six Months as a result of fluctuations in the value of the U.S. Dollar
relative to the DM.

Net losses decreased to $428,000 for the Fiscal 1999 Six Months from $925,000
for the Fiscal 1998 Six Months, primarily as a result of the decrease in
operating losses, partially offset by the increase in foreign currency exchange
losses.

CHANGES IN ACCOUNTING STANDARDS

In February 1997, SFAS 128, Earnings per Share and SFAS 129, Disclosure of
Information About Capital Structure, were issued. SFAS 128 establishes new
standards for computing and reporting earnings per share. SFAS 129 requires an
entity to explain the pertinent rights and privileges of outstanding securities.
The Company has adopted these new standards in the current fiscal year and the
affect of the adoption was not material.

In June 1997, SFAS 130, Reporting Comprehensive Income, was issued. SFAS 130
establishes new standards for reporting comprehensive income and its components
and is effective for fiscal years beginning after December 15, 1997. The Company
expects that comprehensive income (loss) will not differ materially from net
income (loss).

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 February 1998, SFAS 132, Employers' Disclosures about Pensions and other
Postretirement Benefits, was issued. SFAS 132 standardizes the disclosure
requirements for pension and other postretirement pension plans but does not
change the measure or recognition of those plans. SFAS 132 is effective for
fiscal years beginning after December 15, 1997. Management believes that this
pronouncement will have no material effect on the Company's financial statements
or disclosures thereto.

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.

YEAR 2000 COMPLIANCE

The inability of computers, software and other equipment utilizing
microprocessors to recognize and properly process data fields containing a two
digit year is commonly referred to as a Year 2000 Compliance issue. As the year
2000 approaches, such systems may be unable to accurately process certain
data-based information. The Company is in the process of identifying and
modifying all significant hardware and software applications that will require
modification to ensure Year 2000 Compliance. Internal and external resources are
being used to make the required modification and test Year 2000 Compliance. The
estimated cost to address Year 2000 issues is not expected to have a material
impact on the Company's business, operations or financial condition.

In addition, the Company is communicating with external service providers to
ensure that the external providers are taking the appropriate action to address
Year 2000 issues. However, there can be no assurance that the systems of third
parties on which the Company's systems rely will convert, or that a conversion
that is incompatible with the Company's systems would not have an adverse effect
on the Company's systems.

                         TERMINATION OF LETTER OF INTENT

On or about April 17, 1999, the Company filed a press release disclosing that it
had entered into a non-binding letter of intent to sell substantially all of the
assets of Monitek. The terms of the Letter of Intent expired on July 1, 1999.
The Company has not extended the Letter of Intent and, for the time being, has
ceased negotiations with the potential acquirer.

                         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 Quarterly Report on Form 10-QSB, 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

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
curtail its recurring losses; 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.
