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

ITEM 2.

        The Company operates in two segments as follows: Microelectronics
Equipment and Semiconductor Products and Processes.

        RESULTS OF CONSOLIDATED OPERATIONS

        Revenues for the June 30, 2000 quarter were $5,167,577 compared with
$6,769,017 for the three months ended June 30, 1999. Notwithstanding this
decline in revenues, the Company's net loss declined from a net loss of $263,953
for the three months ended June 30, 1999 to a net loss of $198,030 for the three
months ended June 30, 2000. For the six months ended June 30, 2000, revenues
were $9,966,622 compared with $13,464,482 for the six month period ended June
30, 1999. Net loss for the first half of 2000 and 1999 was $778,626 and
$857,358, respectively.

        In 1999 the Semiconductor Products and Processes Segment recorded
significant revenue attributable to non-recurring subcontracts related to a
semiconductor fabrication facility for the Defense Microelectronics Activity.
Furthermore, the reassignment of a substantial portion of the Company's
semiconductor engineering staff from government contract chip development work
to internally-funded commercial product development and marketing activities
consistent with the Company's plans to accelerate its entry into the commercial
telecom semiconductor product market resulted in decreased contract revenue in
fiscal 2000.

        Gross margins for the six months ended June 30, 2000 and 1999 were 34.5%
and 27.0%, respectively. The higher gross margins for 2000 are primarily due to
an increase in sales of the Company's higher margin precision instrument
products in the Microelectronics Equipment Segment as well as higher margins in
the Semiconductor Products and Processes Segment. The Company continues to
experience competitive pressures on certain precision instrument products, which
may impact gross margins in the future. The Company's Semiconductor Products and
Processes Segment conducted by JSI is in the process of evolving from a lower
profit margin contract development business to a commercial business focused on
the telecommunications products markets. JMAR believes, but can give no
assurance that, as this evolution progresses, a greater proportion of JMAR's
sales will be generated by higher profit margin commercial semiconductor
products. Therefore, to the extent that the Company's commercial semiconductor
products begin to generate a higher percentage of the Company's revenues, the
Company's gross margins should improve. The Company also expects that as its
patented, laser-driven advanced light products enter the marketplace and gain
acceptance, they will also substantially improve gross profit margins.

        The Company's operating results in 2000 were also impacted by JMAR's
continuing investments to accelerate the time-to-market for several new
high-performance products for the microelectronics marketplace. These
investments include increased payroll costs with the addition of several senior
technical specialists and managers to direct and help speed the Company's new
precision instrument, laser and X-ray product development programs. As discussed
below, the Company-funded product development expenditures that were expensed
totaled $1,048,480 for the six months ended June 30, 2000 compared to $781,492
for the six months ended June 30, 1999.

        Selling, general and administrative ("SG&A") expenses for the three
months ended June 30, 2000 and 1999 were $1,569,068 and $1,849,636,
respectively, and were $3,197,892 and $3,672,912 for the six months ended June
30, 2000 and 1999, respectively. The decrease in SG&A expenses in 2000 is
primarily due to staff and cost reductions in the Microelectronics Equipment
Segment.

        The Company's research, development and engineering program (RD&E)
consists of two types: Customer-Funded RD&E (U.S. government and other
companies) and Company-Funded RD&E. Both types of RD&E are expensed when
incurred. Customer-Funded RD&E costs incurred, included in "Costs


                                       8
<PAGE>   10

of Sales", totaled $1,065,621 and $944,364 for the three months ended June 30,
2000 and 1999, respectively, and $1,690,274 and $2,382,350 for the six month
periods ended June 30, 2000 and 1999, respectively. The decrease in
Customer-Funded RD&E expenditures for 2000 is related to a decrease due to a
delay in the X-ray lithography program funding provided by the Defense Advanced
Research Projects Agency, most of which is directed toward development of JMAR's
X-ray lithography source technology for the commercial semiconductor market.
This funding was received by the Company late in the second quarter. A further
decrease relates to the Company's contract for the development of a unique
microcircuit architecture and devices for the replacement of obsolete integrated
circuits. The Company believes this latter technology has applicability in both
the government and commercial marketplaces. Company-Funded RD&E costs are shown
in "Operating Expenses" and totaled $509,552 and $373,531 for the three months
ended June 30, 2000 and 1999, respectively, and $1,048,480 and $781,492 for the
six months ended June 30, 2000 and 1999, respectively. Hence, total RD&E
expenditures for the three month periods were $1,575,173 and $1,317,895 for 2000
and 1999, respectively, and $2,738,754 and $3,163,842 for the six month periods
in 2000 and 1999, respectively. In addition to these RD&E expenditures,
capitalized product costs related to the semiconductor chips for commercial
telecommunications applications and capitalized software were $397,344 and
$34,777 for the three months ended June 30, 2000 and 1999, respectively, and
$851,698 and $120,492 for the six months ended June 30, 2000 and 1999,
respectively. Including capitalized product and software costs, RD&E
expenditures as a percentage of sales were 38.2% and 20.0% for the three months
ended June 30, 2000 and 1999, respectively, and 36.0% and 24.4% for the six
months ended June 30, 2000 and 1999, respectively. RD&E expenditures is
primarily related to the continued development of PXS point X-ray sources for
lithography for the semiconductor industry and other metrology applications, the
development of a unique microcircuit architecture and devices for the
replacement of obsolete integrated circuits and for a new family of
telecommunications semiconductor products, the development of new software for
the Company's test and measurement systems and the engineering development of
higher performance test, measurement and inspection systems for the
semiconductor, biomedical and disk drive industries.

        Interest expense is significantly less for the second quarter of 2000
versus the second quarter of 1999 due to the payoff of the Company's working
capital line (the "Line") with Comerica Bank in late March 2000. The full
availability of the Line continues in effect and can be drawn down if needed in
the future.

        RESULTS OF SEGMENT OPERATIONS

        Microelectronics Equipment Segment

        Revenue for the three months ended June 30, 2000 as compared to the
three months ended June 30, 1999 for the Microelectronics Equipment Segment
increased $109,588 from $4,207,832 to $4,317,420, or 2.6%. Revenue for the six
month period in 2000 as compared to 1999 for this Segment increased $107,561
from $7,884,562 to $7,992,123, or 1.4%. Due to improved margins, the operating
loss of the Microelectronics Equipment Segment for the three months ended June
30, 2000 as compared to the three months ended June 30, 1999 decreased from a
loss of $305,312 to a loss of $198,207. Operating loss for the six month period
in 2000 as compared to 1999 for this Segment decreased from a loss of $1,046,857
to a loss of $689,384.

        Semiconductor Products and Processes Segment

        Revenue for the three months ended June 30, 2000 as compared to the
three months ended June 30, 1999 for the Semiconductor Products and Processes
Segment decreased $1,711,028 from $2,561,185 to $850,157, or 66.8%. Revenue for
the six month period in 2000 as compared to 1999 for this Segment decreased
$3,605,421 from $5,579,920 to $1,974,499, or 64.6%. The revenues for 1999
included large one-time subcontracts let in 1999 as discussed above. The
revenues of this Segment in 2000 were impacted by the reassignment of certain
engineering staff from government contract chip development work to
internally-funded commercial product development and marketing activities to
introduce a series of semiconductor chips starting in the third quarter of 2000,
also discussed above. Because of the decrease in revenues, as well as the
build-up of the sales and marketing staff and infrastructure related to the
planned introduction of the Company's new


                                       9
<PAGE>   11

commercial semiconductor chips, operating income (loss) for the three months
ended June 30, 2000 as compared to the three months ended June 30, 1999
decreased $140,482 from income of $50,556 to a loss of $(89,926). Operating
income (loss) for the six month period in 2000 as compared to 1999 for this
Segment decreased from income of $223,753 to a loss of $(120,074).


        CONSOLIDATED LIQUIDITY AND FINANCIAL CONDITION

        Cash and cash equivalents at June 30, 2000 and December 31, 1999 were
$8,944,069 and $2,323,127, respectively. The increase in cash and cash
equivalents for the six months ended June 30, 2000 was $6,620,942. That increase
resulted primarily from the exercise of warrants and options, including the
Company's publicly traded warrants, of $16,004,975 offset in part by cash used
in operations of $1,639,181, the payoff of the Company's working capital bank
line of $4,990,000, an increase in other assets of $1,100,415, capital
expenditures of $889,003 and an increase in notes receivable of $692,973.

        JMAR's operations will continue to require the use of working capital.
In the past, the working capital of the Company has generally been funded
through its $5,000,000 working capital line (the "Line") with Comerica Bank (the
"Bank") and through third-party contracts. Although the Company chose to pay off
the outstanding balance of the Line, the availability of the Line is still in
effect. The Line consists of a $5 million primarily formula-based line of
credit. Of that amount, $750,000 is unrestricted with advances on the balance
based on a formula of 80 percent of eligible accounts receivable, 35 percent of
eligible inventories (up to $2.5 million), 50 percent of unbilled revenue on a
long-term contract and up to $500,000 for certain foreign receivables. The Line
contains several covenants relating to, among other matters, the maintenance of
certain minimum income levels and financial ratios, which, if not met by the
Company, could impact the availability of advances pursuant to the Line.

        The remaining funds received from the exercise of warrants and options
will be used to accelerate the Company's development of high-value
semiconductors for the rapidly growing Internet and Telecom markets and to
accelerate the development and commercialization of its other high value
proprietary products, as needed. Management believes that the Company has
adequate resources to fund operations and working capital requirements for the
next twelve months based on the current level of operations and business
conditions.

        At December 31, 1999, the Company had in excess of $27 million of
Federal net operating loss carryforwards, subject to certain annual limitations,
which expire from 2004 through 2014. To the extent the Company has taxable
income in the future, these carryforwards may be used by the Company to reduce
its cash outlay for taxes.

        In April 2000, the Company entered into a series of agreements with Bede
Scientific Instruments Ltd., including a loan of 450,000 British pounds, with
interest accruing at 10% per annum, all due and payable on April 28, 2003. At
June 30, 2000, this loan receivable, including accrued interest, is stated at
$726,003 in the accompanying balance sheet. To the extent the exchange rate
between British pounds and U.S. Dollars changes, the dollar amount of this
receivable will change accordingly.
