                             JMAR TECHNOLOGIES, INC.
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                   (UNAUDITED)


(1) BASIS OF PRESENTATION

        The accompanying consolidated financial statements include the accounts
of JMAR Technologies, Inc. (the "Company") and its subsidiaries. All significant
intercompany balances and transactions have been eliminated in consolidation.

        The accompanying consolidated financial statements have been prepared by
the Company and are unaudited except for the balance sheet as of December 31,
1999. The financial statements have been prepared in accordance with generally
accepted accounting principles, pursuant to the rules and regulations of the
Securities and Exchange Commission. In the opinion of management, the
accompanying consolidated financial statements include all adjustments of a
normal recurring nature which are necessary for a fair presentation of the
results for the interim periods presented. Certain information and footnote
disclosures normally included in financial statements have been condensed or
omitted pursuant to such rules and regulations. 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. Although the Company believes that the disclosures are adequate to
make the information presented not misleading, it is suggested that these
consolidated financial statements be read in conjunction with the financial
statements and the notes thereto included in the Company's Form 10-K for the
year ended December 31, 1999. The results of operations for the three months
ended March 31, 2000 are not necessarily indicative of the results to be
expected for the full year.

(4) SEGMENT INFORMATION

        In 1998, the Company adopted SFAS No. 131, "Disclosures About Segments
of an Enterprise and Related Information", which required the Company to report
operating information by segment. The Company's two Segments offer varying
products and services that are affected by different economic conditions.
Further, the Segments reflect the manner in which the Company now views the
operating segments.

        Microelectronics Equipment Segment: This segment includes the
manufacture, marketing and sale of the Company's measurement and inspection
systems, positioning and motion control systems and biotech processing systems.
This segment also includes the development of the Company's micro-technology
emerging products, including: next-generation X-ray lithography sources and
other non-lithography X-ray systems for inspecting and processing tomorrow's
high-performance microelectronics products; ultra-precision laser machining
systems; and other leading-edge products based on its patented laser technology.

        Semiconductor Products and Processes Segment: Using advanced design and
engineering tools and established foundry relationships with semiconductor
producers, this segment is a "fabless" supplier of semiconductors which focuses
on the development and delivery of high-performance custom microcircuits for a
wide range of commercial, medical and military electronics uses. This segment
also provides high value services related to the upgrade and enhancement of a
CMOS integrated circuit fabrication facility and related wafer processing
technology for the low-volume and prototype manufacture of electronic circuits
used in operational military systems.

        (5) WARRANT AND OPTION EXERCISES

        During the quarter ended March 31, 2000, the Company received net
proceeds of approximately $15.6 million from the exercise of approximately 3.9
million outstanding options and warrants, including its publicly traded
warrants.  Of these funds, $4,990,000 were used to pay down the Company's
working capital line of credit.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS


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

        RESULTS OF CONSOLIDATED OPERATIONS

        Revenues for the March 31, 2000 quarter were $4,799,045 compared with
$6,695,465 for the three months ended March 31, 1999. Notwithstanding this
decline in revenues, the Company's net loss declined slightly from a net loss of
$593,405 for the three months ended March 31, 1999 to a net loss of $580,596 for
the three months ended March 31, 2000.

       The decline in revenues for the first quarter of 2000 was chiefly
attributable to large one-time subcontracts let by the Semiconductor Products
and Processes Segment in the 1999 quarter to outside vendors for technology
licenses and facility construction related to a semiconductor fabrication
facility that the Company developed and installed for the Defense
Microelectronics Activity as well as the reassignment of a substantial portion
of the Company's semiconductor engineering staff from government contract chip
development work to commercial product activities consistent with the Company's
plans to accelerate its entry into the commercial telecomm semiconductor product
market. Revenues for the first quarter of 2000 were also impacted by a delay in
funding related to the Company's X-ray lithography contract with the U.S.
Government in the Microelectronics Equipment Segment.

        Gross margins for the three months ended March 31, 2000 and 1999 were
34.3% and 24.8%, 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 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 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 $538,928 for the three months ended March 31, 2000 compared to $407,961
for the three months ended March 31, 1999.

        Selling, general and administrative ("SG&A") expenses for the three
months ended March 31, 2000 and 1999 were $1,628,824 and $1,823,276,
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 of Sales",
totaled $624,653 and $1,437,986 for the three months ended March 31, 2000 and
1999, respectively. The decrease in Customer-Funded RD&E expenditures for 2000
is related to a



                                       8
<PAGE>   10
decrease of $602,837 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 and a decrease of $210,496 related 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 $538,928 and $407,961 for the three months ended March 31,
2000 and 1999, respectively. Hence, total RD&E expenditures for the three month
periods were $1,163,581 and $1,845,947 for 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 $454,354 and $30,753 for the three months ended March
31, 2000 and 1999, respectively. Including capitalized product and software
costs, RD&E expenditures as a percentage of sales were 33.7% and 28.0% for the
three months ended March 31, 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 and measurement inspection systems for the
semiconductor, biomedical and disk drive industries.

        Interest expense is higher for the first quarter of 2000 versus the
first quarter of 1999 due to increased average borrowings under the Company's
working capital line (the "Line") with Comerica Bank. However, in late March
2000, the Company paid down the Line in its entirety. Therefore, the Company
expects its interest expense to be reduced, accordingly. 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 March 31, 2000 as compared to the
three months ended March 31, 1999 for the Microelectronics Equipment Segment
decreased slightly from $3,676,730 to $3,674,703. However, due to improved
margins, the operating loss of the Microelectronics Equipment Segment for the
three months ended March 31, 2000 as compared to the three months ended March
31, 1999 decreased from a loss of $710,727 to a loss of $491,177.

        Semiconductor Products and Processes Segment

        Revenue for the three months ended March 31, 2000 as compared to the
three months ended March 31, 1999 for the Semiconductor Products and Processes
Segment decreased $1,894,393 from $3,018,735 to $1,124,342, or 62.8%. This
decrease is related to both the large one-time subcontracts let in the 1999
quarter to outside vendors for technology licenses and facility construction
related to a semiconductor fabrication facility that the Company developed and
installed for the Defense Microelectronics Activity as well as the reassignment
of a substantial portion of the Company's semiconductor engineering staff from
government contract chip development work to commercial product activities
consistent with the Company's plans to accelerate its entry into the commercial
telecomm semiconductor product market. Because of the decrease in revenues, as
well as the build-up of the sales and marketing infrastructure related to the
planned introduction of the Company's new commercial semiconductor chips,
operating income for the three months ended March 31, 2000 as compared to the
three months ended March 31, 1999 decreased $172,527 from income of $142,379 to
a loss of $(30,148).

        CONSOLIDATED LIQUIDITY AND FINANCIAL CONDITION

        Cash and cash equivalents at March 31, 2000 and December 31, 1999 were
$13,026,031 and $2,323,127, respectively. The increase in cash and cash
equivalents for the three months ended March 31, 2000 was $10,702,904. That
increase resulted primarily from the exercise of warrants and options, including
the Company's publicly traded warrants, of $15,596,810 and cash provided by
operations of $742,127 offset in part by the payoff of the Company's working
capital bank line of $4,990,000 and an increase in other assets of $610,264.



                                       9
<PAGE>   11

        JMAR's operations will continue to require the use of working capital.
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. In December 1999, the Line was amended to consist
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.

        Subsequent to December 31, 1999, the Company received net proceeds of
approximately $16 million from the exercise of outstanding options and warrants,
including its publicly traded warrants. Of these funds, $4,990,000 were used to
pay down the Line in its entirety (however, the availability of the Line is
still in effect). In addition, these funds 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.
