                   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 and nine
months ended September 30, 2000 are not necessarily indicative of the results to
be expected for the full year.

(2) INVENTORIES

        Inventories are carried at the lower of cost on the first-in, first-out
basis or market and are comprised of materials, direct labor and applicable
manufacturing overhead. At September 30, 2000 and December 31, 1999, inventories

                      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 September 30, 2000 quarter were $3,769,493 compared
with $4,677,464 for the three months ended September 30, 1999. The Company's net
loss increased from a net loss of $438,897 for the three months ended September
30, 1999 to a net loss of $1,027,793 for the three months ended September 30,
2000. For the nine months ended September 30, 2000, revenues were $13,736,115
compared with $18,141,946 for the nine month period ended September 30, 1999.
Net loss for the first nine months of 2000 and 1999 was $1,806,419 and
$1,296,255, respectively.

         In 1999 the Semiconductor Products and Processes Segment recorded
significant revenue attributable to non-recurring subcontracts related to
construction of a semiconductor fabrication facility for the Defense
Microelectronics Activity located in Sacramento, California. Furthermore, this
Segment's fiscal 2000 revenues were affected by the planned 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. In addition, there was a significant decline in shipments of the
Company's precision instrument products in the third quarter of 2000 primarily
related to requests from certain customers to reschedule shipments until the
fourth quarter of 2000 and the delay in shipment of certain products until the
fourth quarter of 2000 due to parts and labor shortages.

        Gross margins for the nine months ended September 30, 2000 and 1999 were
32.5% and 28.9%, respectively. The higher gross margins for the nine months of
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. Gross
margins for the three months ended September 30, 2000 and 1999 were 27.3% and
34.4%, respectively. The lower gross margins for the third quarter of 2000 are
primarily due to the decline in revenues in that period of the Company's
precision instrument products discussed above. 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 $1,534,140 for the nine months ended September 30, 2000 compared to
$1,290,191 for the nine months ended September 30, 1999.



                                       8
<PAGE>   10

        Selling, general and administrative ("SG&A") expenses for the three
months ended September 30, 2000 and 1999 were $1,683,268 and $1,633,779,
respectively, and were $4,881,160 and $5,306,691 for the nine months ended
September 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 of Sales",
totaled $1,052,193 and $906,241 for the three months ended September 30, 2000
and 1999, respectively, and $2,742,467 and $3,288,374 for the nine month periods
ended September 30, 2000 and 1999, respectively. Most of the decrease is related
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. The remainder 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 $485,660 and $508,699
for the three months ended September 30, 2000 and 1999, respectively, and
$1,534,140 and $1,290,191 for the nine months ended September 30, 2000 and 1999,
respectively. Hence, total RD&E expenditures for the three month periods were
$1,537,853 and $1,414,940 for 2000 and 1999, respectively, and $4,276,607 and
$4,578,565 for the nine 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 $543,327 and $15,153 for the three months ended
September 30, 2000 and 1999, respectively, and $1,395,025 and $135,644 for the
nine months ended September 30, 2000 and 1999, respectively. Including
capitalized product and software costs, RD&E expenditures as a percentage of
sales were 55.2% and 30.6% for the three months ended September 30, 2000 and
1999, respectively, and 41.3% and 26.0% for the nine months ended September 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 continued
development of 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, optical network and biomedical
industries.

        Interest expense is significantly less for the three and nine months of
2000 versus the three and nine months of 1999 due to the payoff of the Company's
working capital line (the "Line") with Comerica Bank in late March 2000. The
full $5 million availability of the Line, subject to the formula discussed
below, continues in effect and can be drawn down if needed in the future. The
terms of the Line are described in "Consolidated Liquidity and Financial
Condition" below.

        RESULTS OF SEGMENT OPERATIONS

        Microelectronics Equipment Segment

         Revenue for the three months ended September 30, 2000 as compared to
the three months ended September 30, 1999 for the Microelectronics Equipment
Segment decreased $395,837 from $3,308,632 to $2,912,795, or 12.0%. As discussed
above, there was a significant decline in shipments of the Company's precision
instrument products in the third quarter of 2000 primarily related to requests
from certain customers to reschedule shipments until the fourth quarter of 2000
and the delay in shipment of certain products until the fourth quarter of 2000
due to parts and labor shortages. This decline was offset in part by higher
contract revenues. Revenue for the nine month period in 2000 as compared to 1999
for this Segment decreased $288,276 from $11,193,194 to $10,904,918, or 2.6%.
Due to lower revenues, the operating loss of the Microelectronics Equipment
Segment for the three months ended September 30, 2000 as compared to the three
months ended September 30, 1999 increased from a loss of $595,924 to a



                                       9

loss of $1,081,508. Operating loss for the nine month period in 2000 as compared
to 1999 for this Segment increased from a loss of $1,642,783 to a loss of
$1,770,892.

        Semiconductor Products and Processes Segment

        Revenue for the three months ended September 30, 2000 as compared to the
three months ended September 30, 1999 for the Semiconductor Products and
Processes Segment decreased $512,134 from $1,368,832 to $856,698, or 37.4%.
Revenue for the nine month period in 2000 as compared to 1999 for this Segment
decreased $4,117,555 from $6,948,752 to $2,831,197, or 59.3%. 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 planned 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 commercial telecom 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
commercial semiconductor chips, operating income (loss) for the three months
ended September 30, 2000 as compared to the three months ended September 30,
1999 decreased $121,556 from income of $63,679 to a loss of $(57,877). Operating
income (loss) for the nine month period in 2000 as compared to 1999 for this
Segment decreased from income of $287,434 to a loss of $(177,951).


        CONSOLIDATED LIQUIDITY AND FINANCIAL CONDITION

        Cash and cash equivalents at September 30, 2000 and December 31, 1999
were $8,027,928 and $2,323,127, respectively. The increase in cash and cash
equivalents for the nine months ended September 30, 2000 was $5,704,801. That
increase resulted primarily from the exercise of warrants and options, including
the Company's publicly traded warrants, of $16,110,625 offset in part by cash
used in operations of $1,426,218, the payoff of the Company's working capital
bank line of $4,990,000, an increase in other assets of $1,742,426, capital
expenditures of $1,341,047 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
with interest at prime rate. 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.

        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. The remaining funds
received from the exercise of warrants and options will be used to help
accelerate the Company's development of high-value semiconductors for the
rapidly growing Internet and Telecom markets and to help 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.

        However, the Company has determined that it will require additional
financing to complete the development of some of its high value emerging new
products including a new family of telecommunications semiconductor



                                       10
<PAGE>   12
products and its patented PXS point X-ray sources for lithography for the
semiconductor industry and other metrology applications. In addition to the
above financing needs, additional funds could be required for future
acquisitions should the Company elect to pursue such acquisitions. The Company
believes that it has available to it several potential sources of capital
including private offerings to individual investors and additional debt or
equity sales in the public market. The Company also believes that it has
opportunities for strategic relationships, which may include additional funding,
in order to accelerate the commercialization of its emerging products.

        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. ("Bede"), including a loan (the "Loan") of 450,000
British pounds, with interest accruing at 10% per annum, plus various equity
rights in Bede. At September 30, 2000, this loan receivable, including accrued
interest, is stated at $694,450 in the accompanying balance sheet. The equity
rights included the grant of an option to the Company to buy a 10% equity
interest in Bede on a fully-diluted, pre-IPO basis for 58,375 pounds. Concurrent
with an initial public offering ("IPO") of Bede and the admission to trading of
Bede's shares on the London Stock Exchange on November 6, 2000, the Company
exercised its option into 1,935,500 shares of Bede valued at approximately $5.4
million based upon the IPO share price of 1.90 pounds. In addition, from the IPO
proceeds, Bede will payoff the remaining 391,625 pounds, plus accrued interest,
owed on the unconverted portion of the Loan. There are no contractual
restrictions on the Company's ability to sell the shares it holds in Bede.

PART II - OTHER INFORMATION


ITEM 1. Legal Proceedings

        As reported previously, in March 2000, the Company filed a Declaratory
        Relief Action against Sands Brothers & Co., Inc. ("Sands"), one of its
        former investment bankers seeking a finding that the Company's financial
        services agreement did not apply to the Company's Warrant Redemption
        program. In September 2000, the Company executed a mutual settlement
        agreement with Sands which provided for the complete release of any and
        all claims either party may have had against the other, the Company's
        dismissal of its lawsuit for Declaratory Relief and the termination of
        all aspects of their financial services agreement. No other
        consideration was exchanged between the parties.

        In February 2000, the Company retained Auerbach Pollak & Richardson,
        Inc. ("Auerbach") as warrant solicitation agent in connection with the
        exercise of the Company's publicly traded warrants in March 2000. As
        consideration for its services as warrant solicitation agent, the
        Company paid Auerbach a cash fee ($650,879) equal to 5% of the exercise
        proceeds and issued Auerbach warrants to purchase 189,347 shares of
        Common stock for $5.50 per share (the "Auerbach Warrants"). The Warrant
        Agreement provides that the Auerbach Warrants are not exercisable until
        the first trading day after September 15, 2000 and after the closing
        price of the Company's Common Stock has exceeded $9.50 for any ten out
        of twenty trading days or has averaged $9.50 for any ten consecutive
        trading days. Auerbach has taken the position that the Auerbach Warrants
        are presently exercisable as of September 18, 2000 based on the closing
        prices of the Company's stock in August and September 2000. The Company
        believes that the exercisability provision clearly provides that the
        JMAR share price condition must be satisfied after September 15, 2000
        and that the Auerbach Warrants are not yet exercisable. Auerbach claims
        it has been damaged as a result of trades in the Company's stock it has
        made and/or could have made in reliance upon the Auerbach Warrants
        becoming exercisable on September 18, 2000. In October 2000, the Company
        filed a Declaratory Relief Action in the U.S. District Court in San
        Diego, California against Auerbach seeking a determination that the
        Auerbach Warrants are not presently exercisable. The Company intends to
        contest this matter vigorously and seek such additional remedies as it
        deems to be necessary or appropriate.


ITEM 2. Changes in Securities

         (c)(i) Pursuant to the Board Member Compensation Program adopted by the
         Company in August 1997, the Company issued a total of 308 shares of
         Common Stock to its outside directors as compensation for services as
         directors in August 2000. These transactions were exempt under Section
         4(2) of the Securities Act of 1933.


ITEM 4. Submission of Matters to a Vote of Security Holders
