NOTES TO CONSOLIDATED STATEMENTS

Note 1

Basis of Presentation - The accompanying unaudited financial statements
consolidate the accounts of Spectrum Laboratories, Inc. and its subsidiaries,
SLI Acquisition Corp., Spectrum Europe B.V. and Spectrum Chromatography
(collectively, the Company). All significant intercompany transactions have been
eliminated in consolidation. In the opinion of management, the accompanying
unaudited interim consolidated financial statements contain all adjustments
(consisting only of normal recurring adjustments) necessary to present fairly
the financial position of the Company as of March 30, 2002 and the results of
its operations and its cash flows for the three months ended March 30, 2002 and
March 31 2001. Certain information and footnote disclosures normally included in
the financial statements have been condensed or omitted pursuant to rules and
regulations of the Securities and Exchange Commission, although the Company
believes that the disclosures in the unaudited interim financial statements are
adequate to make the information presented not misleading.

New Accounting Standards - In June 2001, the Financial Accounting Standards
Board (FASB) issued Statement of Financial Accounting Standards No. 142,
GOODWILL AND OTHER INTANGIBLE ASSETS (SFAS No. 142). SFAS No. 142 addresses
financial accounting and reporting for acquired goodwill and other intangible
assets and is effective for fiscal years beginning after December 15, 2001. The
Company has adopted SFAS 142 during the quarter ended March 30, 2002.
Accordingly, under SFAS 142, management has determined there is one reporting
unit and tested the carrying value of goodwill for any impairment losses and has
determined that no impairment exists. Also in accordance with SFAS 142, the
Company has not recorded amortization expense with respect to goodwill during
the three months ended March 30, 2002, while approximately $21,000 amortization
expense was recorded during the three months ended March 31, 2001. Reported net
income for the three months ended March 31, 2001 would be increased by $13,000,
net of related tax effect to $200,000 had goodwill been accounted for in
accordance with SFAS 142. Accordingly, there would have been no affect on basic
earnings per share, and diluted earnings per share would have increased to $.04

In August 2001 the FASB issued Statement of Financial Accounting Standards No.
144, ACCOUNTING FOR THE IMPAIRMENT OR DISPOSAL OF LONG-LIVED ASSESTS (SFAS No.
144). SFAS No. 144 addresses the financial accounting and reporting for the
impairment or disposal of long-lived assets. The Company has adopted SFAS 144
during the quarter ended March 30, 2002 with no material impact on the
consolidated financial statements.

Patents - The Company has acquired patents, which are amortized over their
respective lives. Management evaluates the usefulness of these patents annually
in determining any potential impairment. Current period amortization with
respect to these patents is approximately $15,000. Estimated amortization
expense for the next five years is approximately $60,000 annually, all of which
relates to these patents.

Note 2 - Inventories

Inventories are stated at the lower of cost, determined using the first-in,
first-out method, or net realizable value and are composed of the following (in
thousands):

                   Raw materials                   $     990
                   Work in progress                       68
                   Finished goods                        573
                                                   ----------

                                                   $   1,631
                                                   ==========

Note 3 - Earnings per Share

Basic earnings per share is computed by dividing the net income attributable to
the common stockholders by the weighted average number of common shares
outstanding during the period. There is no adjustment in the net income
attributable to common stockholders. Diluted earnings per share reflects the
potential dilution that could occur from common shares issuable through stock
options (129,811 and 82,238 shares in the 2002 and 2001 fiscal periods,
respectively).

                                       6


Note 4 - Income Taxes

In assessing the realizability of deferred tax assets, management has estimated
that it is likely that approximately $1,500,000 will not be realized. This
valuation allowance represents a portion of net operating loss carryforwards
attained through a prior business acquisition. As further discussed below, tax
law limits the use of an acquired entity's net operating loss carryforwards to
subsequent taxable income of the consolidated entity. Management will continue
to evaluate the realizability of the deferred tax assets by assessing the need
for and amount of a valuation allowance.

At December 29, 2001, the Company had approximately $5.8 million in net
operating loss carryforwards for federal income tax purposes available to offset
future taxable income. Certain of these loss carryforwards are limited to
approximately $298,000 annually. Any unused net operating loss is carried
forward. As a result of the limitation discussed above, it is probable that
$4,500,000 of the Company's net operating loss will expire without utilization.
Loss carryforwards for tax purposes expire in amounts and by fiscal year as
follows: 2004 $1,600,000; 2005 $1,319,000; 2011 $20,000; 2012 $347,000; 2013
$776,000; 2022 to 2026 $299,000 per year; 2027 $275,000.

Note 5 - Product Group Information

The Company's product groups are based on specific product characteristics and
are grouped into laboratory products and operating room disposable products.
Laboratory products consist primarily of: (1) membranes used to concentrate,
separate and purify dissolved or suspended molecules that are sold primarily to
laboratories and (2) hollow fiber membrane devices that allow components
retained by a membrane to be concentrated including filters utilized for micro
and ultrafiltration separations that are sold to biotech and pharmaceutical
companies. Operating room disposable products consist primarily of sterile
plastic surgical drapes and cloth bandages that are sold primarily to hospitals.

Revenue by product group is as follows (in thousands):

                                                    2002        2001
                                                  -------     -------

Laboratory products                               $2,914      $2,868

Item 2. Management's Discussion and Analysis of Financial Condition and Results
        of Operations

The following discussion should be read in conjunction with the Consolidated
Financial Statements of Spectrum Laboratories, Inc. and Notes thereto contained
elsewhere within this Report on Form 10-QSB. Except for the historical
information contained herein, the following discussion may contain
forward-looking statements that involve risks and uncertainties. The actual
future results of the Company could differ materially from those discussed here.
Factors that could cause or contribute to such differences include, but are not
limited to, those discussed in this report and those factors discussed in the
Company's Form 10-KSB for the year ended December 29, 2001 as filed with the
Securities and Exchange Commission and, from time to time, in the Company's
other reports on file with the Commission.

Results of Operations

Sales for the first 3 months of 2002 of $3,254,000 were slightly short of prior
years by $47,000 (1.4%). Laboratory product sales totaled $2,914,000, a slight
increase of $46,000 (1.6%) versus prior year while revenues from operating room
disposables were $340,000, a decrease from prior year of $93,000 (21.5%). The
decrease in operating room disposables revenues is due primarily to lower sales
volume with a number of larger customers.

                                       7


Gross Margin for the first quarter of 2002 was $1,457,000 (44.8%) versus the
first quarter of 2001 of $1,591,000 (48.2%). The decrease in gross margin was
due to product sales mix. The decrease in gross margin was more than offset by
reduced SG&A and research & development expenditures of $146,000 (11.5%) in the
first 3 months of 2002 versus the comparable 2001 period.

The net impact of the above resulted in income before taxes of $305,000 in the
first quarter of 2002 versus $310,000 in the first quarter of 2001, a slight
decrease of $5,000 (1.6%).

Liquidity and Capital Resources

During the first three months of fiscal 2002, the Company generated
approximately $341,000 of cash from operating activities. This was offset by
$206,000 in bank loan payments, $250,000 relating to the acquisition of patents
and $46,000 for purchases of equipment and costs for leasehold improvements.
This resulted in a net decrease in cash for the period of approximately
$161,000.

The Company's management believes that cash on hand, cash expected to be
generated from operations and, to any extent necessary, usage of the
availability of additional borrowings will be sufficient to meet cash
requirements for the next twelve months.
