                             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. (formerly JMAR Industries, 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,
1997. 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, 1997. The results of operations for the three and nine
months ended September 30, 1998 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, 1998 and December 31, 1997, inventories
consist of the following:

(4)     EARNINGS PER SHARE

        In 1997, the Company adopted FASB Statement No. 128 ("SFAS No. 128"),
Earnings per Share, effective December 15, 1997. There was no change to
previously reported earnings per share as a result of the adoption of this new
Financial Accounting Standard.

(5)     NEW ACCOUNTING PRONOUNCEMENTS

        In 1998, the Company adopted FASB Statement No. 130 ("SFAS 130"),
Reporting Comprehensive Income. SFAS 130 requires the reporting of additional
financial information. At September 30, 1998, there was no difference in the
Company's Net Income and Comprehensive Income.

        In February, 1998, the Financial Accounting Standards Board (FASB)
issued SFAS No. 132, "Employers' Disclosures About Pensions and Other
Postretirement Benefits". SFAS No. 132 revises and standardizes employers'
disclosures about pension and other postretirement benefits, but it does not
change the measurement or recognition of those benefits. SFAS No. 132 is
effective for fiscal years beginning after December 15, 1997. SFAS No. 132
further requires restatement of disclosures for earlier periods provided for
comparative purposes. Management believes that the adoption of SFAS No. 132 will
not have any impact on the Company's consolidated financial statements or
disclosures thereto.

        In March, 1998, the Accounting Standards Executive Committee (AcSEC)
issued AICPA Statement of Position (SOP) 98-1, "Accounting for costs of computer
software developed or obtained for internal use". This statement provides
guidance on accounting for the costs of computer software developed or obtained
for internal use and identifies characteristics of internal-use software and
provides assistance in determining when computer software is for internal use.
SOP 98-1 is effective for fiscal years beginning after December 15, 1998, with
earlier application permitted. The Company believes that the adoption of SOP
98-1 will have no significant impact on the Company's consolidated financial
statements, results of operations, or related disclosures thereto.

        The Company will be required to adopt the FASB's Statement of Financial
Accounting Standards No. 131 ("SFAS 131"), "Disclosures about Segments of an
Enterprise and Related Information." SFAS 131 superseded FASB Statement No. 14,
Financial Reporting for Segments of a Business Enterprise. SFAS 131 established
standards for the way that public business enterprises report information about
operating segments in annual financial statements and requires that those
enterprises report selected information about operating segments in interim
financial reports. SFAS 131 also establishes standards for related disclosures
about products and services, geographic areas, and major customers. The adoption
of SFAS 131 will not affect the results of operations or financial position, but
may affect the disclosure of the segment information that will be disclosed in
the Annual Report on Form 10-K for the year ended December 31, 1998.

        In April, 1998, AcSEC issued SOP 98-5, "Reporting on the costs of
start-up activities". This statement provides guidance on financial reporting of
start-up costs and organization costs and requires that such costs of start-up
activities be expensed as incurred. SOP 98-5 is effective for fiscal years
beginning after December 15, 1998, with earlier application permitted. The
Company believes that the adoption of SOP 98-5 will have no significant impact
on the Company's consolidated financial statements, results of operations, or
related disclosures thereto.

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

ITEM 2.

        RESULTS OF CONSOLIDATED OPERATIONS

        Operating income, income before taxes and net income for the three month
period ending September 30, 1998 were $324,387, $301,937 and $301,937,
respectively, compared with $261,063, $235,053 and $300,053, respectively, for
the quarter ended September 30, 1997. Therefore, operating income and income
before tax increased 24 percent and 28 percent, respectively. Although net
income was approximately the same for the two periods, net income for the
quarter ended September 30, 1997 including a tax benefit of $65,000 compared
with no benefit recorded for the quarter ended September 30, 1998. Revenues for
the three month period ended September 30, 1998 were $5,799,458 compared with
$5,583,611 for the three month period ended September 30, 1997.

        Operating income, income before taxes and net income for the nine months
ended September 30, 1998 were $654,759, $619,141 and $619,141, respectively,
compared to $588,411, $521,532 and $686,532, respectively, for the nine months
ended September 30, 1997. Included in the net income for the nine months ended
September 30, 1997 is a tax benefit of $165,000 compared with no benefit
recorded in the net income for the nine months ended September 30, 1998.
Revenues for the nine months ended September 30, 1998 and 1997 were $16,162,974
and $16,397,718, respectively.

        The increase in revenues of $215,847 for the three months ended
September 30, 1998 compared to the three months ended September 30, 1997 is due
to the increase in revenue generated by the Company's continuing X-ray
lithography source development program funded by the Defense Advanced Research
Projects Agency (DARPA) and the Company's integrated circuit technology and
fabrication program funded by contracts from two major U.S. aerospace
corporations. These increases were partially offset by a decline in revenues of
the Company's precision instruments and systems due to marketplace
uncertainties, including Asian economic problems, and a significant downturn in
the worldwide semiconductor industry.

        The decrease in revenues of $234,744 for the nine months ended September
30, 1998 compared to 1997, is primarily attributable to the decline in sales of
the Company's precision instrument products primarily due to reduced demand by
the computer disk drive industry offset in part by increases in the Company's
semiconductor-related business primarily in X-ray lithography and semiconductor
design and process development. The Company's ability to forecast orders for its
precision instrument products continues to be somewhat limited due to continuing
marketplace uncertainties. However, because of a substantial recent increase in
orders for its semiconductor products and services, the Company believes that
its consolidated sales revenue for both the fourth quarter and the full year
could be greater than they were for the same periods of 1997.

        Gross margins for the nine months ended September 30, 1998 and 1997 were
38.7% and 39.9%, respectively, and for the three months ended September 30, 1998
and 1997 were 40.6% and 41.0%, respectively. The lower gross margins for 1998
are primarily due to competitive pricing pressures on certain products, higher
engineering costs related to the customization of certain products for new
applications and increases in semiconductor-related business at JMAR
Semiconductor and JMAR Research. These decreases were offset in part by lower
material costs due to higher volume purchases of inventory related to certain
product orders and cost reductions in the manufacturing process. The Company
expects continued competitive pressures on certain products. In addition, to the
extent that the Company's semiconductor-related business at JMAR Semiconductor
and JMAR Research continues to represent a higher percentage of the Company's
total revenues, the Company's margins may be lower in the future.

        Selling, general and administrative ("SG&A") expenses for the three
months ended September 30, 1998 and 1997 were $1,565,580 and $1,582,770,
respectively, and were $4,380,632 and $4,631,299 for the nine months ending
September 30, 1998 and 1997, respectively. The decrease in SG&A expenses for the
nine months ended September 30, 1998 compared to the nine months ended September
30, 1997 is primarily due to a decrease in SG&A expenses of approximately
$447,000 related to the reorganization of JMAR Semiconductor (formerly
California ASIC) at the end of 1997 partially offset by higher payroll costs and
higher investor relations costs.

        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"
expenses, totaled $709,413 and $324,759 for the three months ended September 30,
1998 and 1997, respectively, and $1,558,776 and $903,344 for the nine month
periods ended September 30, 1998 and 1997, respectively. Company-Funded RD&E
costs are shown in "Operating Expenses" and totaled $462,694 and $445,283 for
the three months ended September 30, 1998 and 1997, respectively, and $1,225,253
and $1,325,796 for the nine month periods ended September 30, 1998 and 1997,
respectively. Therefore, total RD&E expenses for the three month periods were
$1,172,107 and $770,042 for 1998 and 1997, respectively, and $2,784,029 and
$2,229,140 for the nine month periods in 1998 and 1997, respectively. The
increase in the Customer-Funded RD&E is primarily related to an increase in the
X-ray lithography program funding provided by DARPA.

CONSOLIDATED LIQUIDITY AND FINANCIAL CONDITION

        Cash and cash equivalents at September 30, 1998 and December 31, 1997
were $3,639,945 and $3,644,117, respectively. The decrease in cash and cash
equivalents for the nine months ended September 30, 1998 was $4,172 as compared
to a decrease of $417,023 for the nine months ended September 30, 1997. The
decrease in cash for the nine months ended September 30, 1998 resulted primarily
from cash used in operations of $1,781,082, mainly to fund the growth in the
Company's accounts receivable balance, capital expenditures of $572,596 and net
payments of notes payable of $280,071 offset in part by net short term bank
credit line borrowings of $2,525,000 and net proceeds from the exercise of
options and warrants and repurchases of stock of $133,299. A significant portion
of the receivable growth was driven by the timing of billings and related cash
collections on certain long-term contracts. Cash from net income plus non-cash
operating items for the nine months ended September 30, 1998 was $1,207,743.

        JMAR's operations will continue to require the use of working capital.
The working capital of the Company is generally funded through its working
capital line with Comerica Bank (the "Bank") and through third party contracts.
In 1998, the Bank increased the Company's credit availability from $3.5 million
to $6.0 million (the "Line"). The new banking arrangement provides a revolving
line of credit to JMAR for up to $5 million bearing interest at the Bank's prime
rate, plus an additional $1 million five-year term credit line at the Bank's
prime rate for financing equipment purchases and construction of prototype
product demonstration systems such as the Company's new Britelight lasers. This
is in addition to an existing $729,000 equipment financing loan previously made
by the Bank. As of October 31, 1998, JMAR's availability pursuant to the Line
was approximately $5,950,000. 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 Company is in compliance with all
covenants. Management believes that the Company has existing resources to
adequately fund operations and working capital requirements at least through
September 30, 1999 based on the current level of operations and business
conditions.

        In September, 1998, the Board of Directors authorized the repurchase,
from time-to-time of up to $2,000,000 of its own shares of common stock in the
open market, or in negotiated transactions, when they are available at prices
the Company considers attractive. As of November 4, 1998, the Company had
repurchased approximately 200,000 shares pursuant to this repurchase program.

        At December 31, 1997, the Company had in excess of $25 million of
Federal net operating loss carryforwards, subject to certain annual limitations.
To the extent the Company has taxable income in the future, these carryforwards
will be used by the Company to reduce its cash outlay for taxes.

YEAR 2000 ISSUE

        The "Year 2000 Issue" is the result of computer systems not being able
to distinguish the year 2000 from the year 1900. This issue affects virtually
every business, including the Company's, and can affect both the Company's
internal information systems, the equipment and components it buys from others
and the products it sells.

        In early 1998, the Company formed a task force to assess the nature,
extent and cost of remediation of any Year 2000 compliance issues confronting
the Company and its suppliers. This project encompasses a review of the
Company's internal systems and products as well as its suppliers' compliance.
This assessment has been substantially completed at the Company's Precision
Systems division and is underway in its Research and Semiconductor divisions. As
a result of its assessment process, the Company has identified certain
corrective actions which may be required. Some of these actions have already
been taken and others remain to be completed. Based upon its understanding of
the corrective actions which may be required, the Company expects to complete
all required actions by mid-1999.

        In connection with its assessment of the Year 2000 issues, the Company
has sent out letters to its customers advising them of the Year 2000 issue and
providing them with a testing procedure to diagnose any potential problems which
may arise with Year 2000 issues. The Company has also sent questionnaires to its
key suppliers requesting information regarding their own Year 2000 compliance
efforts, as well as requesting confirmation that the components and services
provided by those suppliers are Year 2000 compliant.

        Based upon its initial assessment, the Company believes that Year 2000
issues at its facilities should not have a material impact on the Company's
financial or operating performance. Although the Company believes that it is
justified in relying upon the information it has obtained from its key
suppliers, the Company has not obtained and does not intend to obtain
independent confirmation of its suppliers' Year 2000 compliance and, therefore,
no assurances can be given that the companies upon which the Company relies will
timely resolve their own Year 2000 compliance issues.

        The costs to implement the Company's Year 2000 plan are primarily the
time devoted by personnel to assess the Year 2000 issues, to communicate with
suppliers and customers and to formulate and implement any necessary changes. It
is the Company's policy to expense such costs as incurred. To date, the
financial impact to the Company of assessing and implementing the changes
required to address the Year 2000 issue has not been material to the Company's
business, operations, financial condition, liquidity and capital resources.
Based upon the Company's current assessment, the Company does not expect the
Year 2000 issue to have a material impact on its business, operations, financial
condition, liquidity and capital resources in the future.
