recurring adjustments) necessary to present fairly the financial position of the
Company as of March 31, 2001 and the results of its operations and its cash
flows for the three months ended March 31, 2001 and April 1, 2000. 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.

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                                  $  1,202
                   Work in progress                                     87
                   Finished goods                                      777
                                                                  ---------

                                                                  $  2,066
                                                                  =========

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 (82,238 and 134,822 shares in the 2001 and 2000 fiscal periods,
respectively).

Note 4 - Income Taxes

In assessing the realizability of deferred tax assets, management has estimated
that it is more likely than not 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 30, 2000, the Company had approximately $6.1 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 $988,000; 2005 $1,319,000; 2011 $20,000; 2012 $347,000; 2013
$776,000; 2014 to 2021 $299,000 per year; 2022 $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):

                                                    2001             2000
                                                 ----------       ----------

Laboratory products                              $   2,868        $  2, 910

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 30, 2000 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

Research and development expenses increased approximately 17% for the first
three months of fiscal 2001 as compared to the same period of the prior year and
was primarily due to certain one-time costs related to a project.

Income taxes - The Company has applied a valuation allowance on its net deferred
tax assets which exceed the recoverability of those assets from estimated future
taxable income for the next three years. This valuation allowance could change
substantially in future years due to changes in estimates of future taxable
income and changes in the components of the deferred tax assets. Accordingly,
income taxes as a percentage of income before income taxes could vary
significantly in future years.

Liquidity and Capital Resources

During the first three months of fiscal 2001, the Company generated
approximately $624,000 of cash from operating activities. This was offset by
$205,000 in bank loan payments, $500,000 for an acquisition of patents (which
are being amortized over approximately twelve years) and $252,000 for purchases
of equipment and costs for leasehold improvements. This resulted in a net
decrease in cash for the period of approximately $333,000.

The Company has a credit agreement with a bank that prohibits payment of cash
dividends without prior bank approval. The Company does not intend to pay cash
dividends in fiscal 2001. In January, 2001, the credit agreement was amended to
provide up to $900,000 of additional borrowings for certain purposes as defined
in the amendment.

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.

In October 1996, a subsidiary of the Company, SLI Acquisition Corp. (SLIAC),
acquired certain assets and liabilities of Cellco, Inc. in exchange for 10,000
shares of SLIAC's preferred stock valued at $2,000,000 for redemption purposes.
At March 31, 2001, there is $1,755,000 of the preferred stock still outstanding.
Beginning October 1, 2000, and continuing until September 30, 2001, the holders
of the preferred stock have the right to put their stock to SLIAC for an
aggregate price of $1,755,000. In the event SLIAC is combined with the Company
and the combined company completes an underwritten offering, the preferred
stockholders have the right to exchange such stock for 7% of the newly combined
company. Management anticipates that this subsidiary will be liquidated prior to
December 31, 2001, if the put is exercised and the subsidiary does not perform
under the put. The put obligation is that of the subsidiary and not the Company.
