                             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,
1998. 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, 1998. The results of operations for the three months
ended March 31, 1999 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 March 31, 1999 and December 31, 1998, inventories

(4)     ADOPTION OF NEW ACCOUNTING PRONOUNCEMENTS

        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 adoption of SOP 98-1 did not have a
significant impact on the Company's consolidated financial statements, results
of operations, or related disclosures thereto.

        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
adoption of SOP 98-5 did not have a significant impact on the Company's
consolidated financial statements, results of operations, or related disclosures
thereto.

(5)     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. In the Company's Form 10-K for the year ended
December 31, 1998, three segments were reported. These three segments were the
Precision Systems Segment, the Contract Research and Development Segment, and
the Semiconductor Products and Processes Segment.

     During the quarter ended March 31, 1999, the Company combined the Precision
Systems and Contract Research and Development Segments to form the
Microelectronics Equipment Segment. The Company's two Segments offer varying
products and services which are affected by different economic conditions.
Further, the Segments reflect the manner in which the Company now views the
operating segments.

                                   (UNAUDITED)


   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 laser 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 manufacturing and inspecting tomorrow's
high-performance semiconductors; ultra-precision laser machining systems; and
other leading-edge products based on its patented laser technology.

   Semiconductor Products and Processes Segment: Using advanced tools and
established foundry relationships with semiconductor producers, this "fab-less"
supplier of semiconductors focuses on the development and delivery of
high-performance customer 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. 

Segment information for the three months ended March 31, 1999 and 1998 was as
follows:

(6)     SHAREHOLDER RIGHTS PLAN

        In February 1999, the Company adopted a Shareholder Rights Plan, and
subsequently declared a dividend of one Preferred Share Purchase Right for each
outstanding share of JMAR common stock held by shareholders of record at the
close of business on March 5, 1999. The Rights and Rights Plan expire on
February 12, 2009.

   Each Right will entitle shareholders to buy one one-thousandth (1/1000th) of
a share of JMAR's Series A Junior Participating Preferred Stock at an exercise
price of $25.00. Initially, the Rights will not be exercisable and will be
attached to and trade together with shares of JMAR common stock. Subject to
limited exceptions, the Rights will become exercisable 10 days after a person or
group announces that it has acquired 15 percent or more of JMAR's common stock
or announces commencement of a tender or exchange offer for 15 percent or more
of JMAR's common stock.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (CONTINUED)
                                   (UNAUDITED)


        Once exercisable, each Right not owned by the acquiring person or group
will entitle its holder to purchase that number of shares of JMAR's common stock
having a market value of twice the Right's current exercise price. In addition,
if JMAR is acquired in a merger or other business combination transaction, the
acquiring entity must assume the obligations under the Rights and the Rights
will become exercisable to acquire common stock of the acquiring entity at a 50
percent discount.

        JMAR's Board may redeem the Rights for $.0001 per Right at any time on
or before the tenth day following acquisition by a person or group of 15 percent
or more of JMAR's common stock. In addition, at any time after an event
triggering exercisability of the Rights and prior to the acquisition by the
acquiring person of 50 percent or more of JMAR's common stock, the Board of
Directors of JMAR may also exchange each Right for one share of common stock of
JMAR.

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

ITEM 2.

        The Company operates in two segments as follows: Microelectronics
Equipment Segment and Semiconductor Products and Processes Segment. Note 5 to
the Consolidated Financial Statements discusses the changes in the way the
Company reports its operating segments.

   RESULTS OF CONSOLIDATED OPERATIONS

     Net income (loss) for the three months ended March 31, 1999 and 1998 were
$(593,405) and $18,083, respectively. However, revenues increased 56% to
$6,695,465 for the three months ended March 31, 1999 from $4,300,079 for the
three months ended March 31, 1998.

     The significant improvement in revenues to the highest level for any first
quarter in the Company's history was chiefly attributable to sustained growth in
the Semiconductor Products and Processes Segment and expanded contract activity
in the Company's X-ray lithography development program.  Offsetting these
increases was a decline in 1999 shipments of the Company's precision instrument
products related to decreased demand from Asian markets and requests from
certain customers to reschedule shipments until later in 1999.   As a result of
an increase in orders in the precision instrument products which started in the
first quarter of 1999, the Company anticipates that revenues and profits will
increase in the remainder of the year.

     The Company's profits were also impacted by JMAR's continuing investments
to accelerate the time-to-market for several new high-performance products for
the microelectronics marketplace.  As discussed below, the Company's product
development expenditures, including that portion of customer-funded efforts
directly attributable to the commercialization of JMAR's proprietary
technologies, were 28 percent of revenues in the first quarter of 1999.
Additionally, payroll costs increased 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 products to market.

   Gross margins for the three months ended March 31, 1999 and 1998 were 24.8%
and 38.7%, respectively. To the extent that the Company's rapidly expanding
semiconductor-related business continues to represent a higher percentage of the
Company's revenues, the Company's gross margins could be lower compared to 1998.

   Selling, general and administrative ("SG&A") expenses for the three months
ended March 31, 1999 and 1998 were $1,823,276 and $1,309,738, respectively. The
increase in SG&A expenses in 1999 is primarily due to higher payroll costs
related to the addition of senior technical and management staff.

   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 "Contract Costs of Sales",
totaled $1,437,986 and $417,348 for the three months ended March 31, 1999 and
1998, respectively. The increase in Customer-Funded RD&E expenditures for 1999
is related to an increase of $718,786 in the X-ray lithography program funding
provided by DARPA, most of which is directed toward commercialization of JMAR's
X-ray lithography source technology and $301,852 related to the Company's
contract for the development of a unique microcircuit architecture and devices
for the replacement of obsolete integrated circuits. Company-Funded RD&E costs
are shown in "Operating Expenses" and totaled $407,961 and $332,801,
respectively. Hence, total RD&E expenses for the three month periods were
$1,845,947 and $750,149, respectively. Capitalized software costs of $30,753 and
$135,247 for the three months ended March 31, 1999 and 1998, respectively, are
not included in the above amounts. Including capitalized software costs, RD&E
expenditures as a percentage of sales were 28% and 20.6% for the three months
ended March 31, 1999 and 1998, respectively. The increase in 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 commercial laser systems, the development of new
software for the Company's test and measurement 



                                       9
<PAGE>   11

systems and the engineering development of higher performance test and
measurement inspection systems for the disk drive and semiconductor industries.

   RESULTS OF SEGMENT OPERATIONS

   Microelectronics Equipment Segment

    Revenue for the Microelectronics Equipment Segment decreased $450,487 from
$4,127,217 to $3,676,730, or 10.9 percent. This decrease reflects lower
shipments of precision instruments to the computer industry primarily related to
decreased demand from Asian markets. Additionally, the Company had customer
requested shipping delays related to precision instrument products. As a result,
the Microelectronics Equipment Segment operating income was adversely affected
as well, decreasing $820,286 from income of $109,559 to a loss of $710,727. This
decrease reflects the decrease in revenues of the higher margin precision
instruments as well as an increase in product development expenditures.

   Semiconductor Products and Processes

    The Semiconductor Products and Processes Segment experienced significant
growth in revenues of $2,845,873 from $172,862 to $3,018,735.  This growth
reflects the receipt in the last half of 1998 of two significant contracts from
General Dynamics Information Systems and TRW funded by the Defense
Microelectronics Activity. Because of the increase in revenues, operating income
increased $231,661 from a loss of $89,282 to income of $142,379.

   CONSOLIDATED LIQUIDITY AND FINANCIAL CONDITION

     Cash and cash equivalents at March 31, 1999 and December 31, 1998 were
$3,695,978 and $3,848,183, respectively. The decrease in cash and cash
equivalents for the three months ended March 31, 1999 and 1998 was $152,205 and
$88,328, respectively. The decrease in cash for the three months ended March 31,
1999 resulted primarily from payments of the Company's working capital bank line
of $600,000, net payments of notes payable of $116,923, repurchases of stock of
$110,776, capital expenditures of $50,658 and patent costs of $22,207 offset in
part by cash provided by operations of $745,595.

        JMAR's operations will continue to require the use of working capital.
The working capital of the Company is generally funded through its $5,000,000
working capital line (the "Line") with Comerica Bank (the "Bank") and through
third party contracts. The Line provides for the accrual of interest at the
Bank's "prime rate". As of May 7, 1999, JMAR's availability pursuant to the Line
was $4,500,000. 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. Management believes that the Company has existing
resources to adequately fund operations and working capital requirements through
the end of 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 May 7, 1999, the Company had repurchased
234,300 shares pursuant to this repurchase program at a total cost of $446,833.

        At December 31, 1998, the Company had in excess of $25 million of
Federal net operating loss carryforwards, subject to certain annual limitations,
which expire from 2004 through 2011. 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.

YEAR 2000 ISSUES

        The "Year 2000 Issue" is the result of computer systems, embedded
semiconductors and related items 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 with regard to the Company's
internal information systems and at all of the Company's three divisions. As a
result of its assessment process, the Company has identified certain corrective
actions which may be required. The Company has completed the corrective actions
required to be taken with regard to its internal information systems and
believes such systems are compliant. With regard to its products, the Company
has taken several corrective actions 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. The Company is
continuing to assess and reassess its Year 2000 issues as it obtains additional
information and test procedures from Sematech and other industry groups.

        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 in
equipment supplied to them by the Company. 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. To
date, the Company has not received any responses which indicate that the
Company's products have Year 2000 problems or that its suppliers have any Year
2000 problems. The Company is continuing to follow-up with those suppliers who
have not responded to its surveys.

        Based upon its ongoing assessment process, the Company believes that
Year 2000 issues related to its internal systems and its products 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 and confirmations it has obtained from its key suppliers, the
Company 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. The Company estimates
that its total cumulative labor costs incurred in connection with its Year 2000
assessment and remediation efforts over more than one year is approximately
$50,000 and its other expenses over the same period are less than $10,000. 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.
