NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)

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

Unaudited Interim Financial Statements - The unaudited consolidated financial
statements and related notes have been prepared pursuant to the rules and
regulations of the Securities and Exchange Commission (SEC). Accordingly,
certain information and footnote disclosures normally included in financial
statements prepared in accordance with accounting principles generally accepted
in the United States of America have been omitted pursuant to such rules and
regulations. The accompanying consolidated financial statements of the Company
should be read in conjunction with the audited consolidated financial statements
of the Company, and notes thereto, for the year ended December 25, 2004. The
information furnished reflects, in the opinion of management, all adjustments,
consisting of normal recurring accruals, necessary for a fair presentation of
the results of the interim periods presented. Operating results of the interim
period are not necessarily indicative of the amounts that will be reported for
the year ending December 31, 2005.

Long-lived Assets - The Company recognizes impairment losses for long-lived
assets used in operations when indicators of impairment are present and the
future undiscounted cash flows are not sufficient to recover the assets'
carrying amount. Management believes there has been no impairment of the value
of such assets. The analysis of indicators of impairment and future cash flows
are estimates made by management.

Patents - The Company has acquired patents utilized within the various
manufacturing processes. These patents are amortized over their respective
lives, typically 17 years. Management believes there has been no impairment in
the value of these patents.

Estimates & Reserves - The Company's principal reserves relate to accounts
receivable and inventory. A detailed review of these reserves is done annually
with a general review quarterly. The Company believes these reserves are
adequate and the amounts are consistent with prior year's level. A significant
estimate is made in the annual impairment testing of goodwill. Changes in
management's estimate of fair value of the Company could result in future
impairment charges.

Accounting for Stock-based Compensation - The Company accounts for stock-based
employee compensation under the requirements of Accounting Principles Board
(APB) Opinion No. 25, which does not require compensation to be recorded if the
consideration to be received is at least equal to fair value at the measurement
date. Nonemployee stock-based transactions are accounted for under the
requirements of the Financial Accounting Standards Board's (FASB) Statement of
Financial Accounting Standards (SFAS) No. 123, "ACCOUNTING FOR STOCK-BASED
COMPENSATION", which requires compensation to be recorded based on the fair
value of the securities issued or the services received, whichever is more
reliably measurable.

SFAS No. 123 requires the disclosure of pro forma net income and earnings per
share had the Company adopted the fair value method. Under SFAS No. 123, the
fair value of stock-based awards to employees is calculated through the use of
option-pricing models, even though such models were developed to estimate the
fair value of freely tradable, fully transferable options with vesting
restrictions which significantly differ from the Company's stock option awards.
These models also require subjective assumptions, including future stock price
volatility and expected time to exercise, which greatly affect the calculated
value.

The calculations are based on a single-option valuation approach and forfeitures
are recognized as they occur. The following table illustrates the effect on net
income and earnings per share had compensation cost for stock-based compensation
been determined based on the grant date fair values of awards (in thousands
except share data - refer to next page for table):

The Company was not in compliance with one of its loan covenants as of September
24, 2005 relating to cash flow to debt coverage. The Company received a covenant
violation waiver from its bank on November 14, 2005.

Note 2 - Inventories

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

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 are a combined total of 918,674 options and
warrants outstanding as of September 24, 2005, as disclosed in Note 6 - Option
Plan. Diluted earnings per share reflect the potential dilution that could occur
from common shares issuable through stock options and warrants (244,053 and
157,126 equivalent shares in the three and nine month periods ending September
24, 2005, respectively and 277,252 and 263,009 equivalent shares in the three
and nine month periods ending September 25, 2004, respectively).

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 25, 2004, the Company had approximately $5.2 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
approximately $1.5 million of the Company's net operating loss will expire
without utilization.

Note 5 - Product Group Information

While management has determined the Company operates as a single reportable
segment, the Company's product groups are based on specific product
characteristics and are grouped into bioprocessing products ("BioProcessing"),
formerly referred to as laboratory products, and disposable operating room
products ("OR"). BioProcessing products consist primarily of membranes and
modules used to filter, extract, concentrate, separate and purify. These
products are sold primarily to laboratories, research institutions, biotech and
pharmaceutical companies. OR products consist primarily of sterile surgical
drapes and bandages that are sold primarily to hospitals and their suppliers.

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

                          ==========     ==========    ==========     ==========


Note 6 - Option Plan

The Company has an option plan referred to as the 2000 Option Plan (the "2000
Option Plan" or "Plan") with 600,000 shares of common stock reserved for option
grants to key employees, directors and consultants. Exercise prices for the
stock options will not be less than 100% of the fair market value of the stock
on the date of grant. Options under the Plan expire not more than ten years from
date of grant. Options under the Plan become exercisable over a 5 year period
(20% per year). As of September 24, 2005, there were 528,050 options outstanding
under the 2000 Option Plan. There were no options granted and 46,000 options
forfeited during the nine months ended September 24, 2005.

In addition to the 2000 Option Plan there are 265,624 non qualified stock
options outstanding and 125,000 warrants.

Note 7- Comprehensive Income

Comprehensive income is comprised of net income and Other Comprehensive Income
("OCI"). OCI includes certain changes in stockholders' equity that are excluded
from net income. Specifically, the Company includes in OCI changes in the fair
value of unrealized gains and losses on Spectrum's available for sale
securities. The activity in comprehensive income during the nine month period
ended September 24, 2005 was as follows (in thousands):

BioProcessing sales were $493,000 (5.5%) below prior year. The underperformance
in BioProcessing was attributable to one OEM customer, with sales in excess of
$750,000 in 2004 and no sales in 2005.

Gross Margin

Gross margin for the third quarter of 2005 was $1,439,000 (42.2%) versus prior
year third quarter margin of $1,548,000 (43.4%). Year to date gross margin for
2005 was $4,144,000 (42.5%) versus prior year of $4,434,000 (43.6%).

Selling, General & Administrative ("SG&A") and Research & Developmental Expenses
("R&D") During the third quarter of 2005 R&D expenses were $246,000 while SG&A
expenses were $1,069,000 resulting in an increases in R&D expenses of $25,000
(11.3%) while SG&A expenses increased $64,000 (6.4%), when compared to third
quarter of 2004. On a year to date bases R&D expenses total $674,000, an
increase of $59,000 (9.6%) over 2004 while SG&A expenditures total $3,149,000,
an increase over 2004 of $245,000 (8.4%) The increase in R&D expenses
principally related to outside consultants and materials associated with the
expansion of Spectrum's product line, partially offset by a specific consulting
agreement with a university in 2004 that totaled approximately $25,000.

The increase in SG&A was comprised of approximately $50,000 associated with the
going private process, $67,000 related to translating its European subsidiary
balance sheet and approximately $115,000 in increased management expenses
attributable to Spectrum's new President. The net of these increased expenses
were partially offset by a reversal of a management accrual of approximately
$50,000 and other miscellaneous expenses totaling approximately $63,000.

Net Income

Considering the above, net income for the third quarter was $84,000 versus
$110,000 in the third quarter of 2004. On a year to date basis, net income was
$70,000 compared to 2004 year to date net income of $495,000.

Liquidity and Capital Resources

Cash provided by operations for the first nine months of 2005 was $138,000.
Working capital components consumed cash of $444,000 principally due to the
increase in accounts receivable of $285,000 and the decrease in accrued expenses
of $125,000. Cash flow was also impacted by financing activity relating to
$680,000 in bank loan payments, $75,000 in investing activity associated with
the acquisition of equipment and a current net investment in marketable
securities of $395,000. The net of this activity resulted in a net decrease in
cash for the first nine months of 2005 of $1,012,000 resulting in a cash balance
at September 24, 2005 of $7,107,000.

Spectrum was not in compliance with one of its loan covenants as of September
24, 2005 relating to cash flow to debt coverage. The Company received a covenant
violation waiver from its bank on November 14, 2005.

In December of 2001 Spectrum entered into specific research, licensing,
manufacturing and supply agreements (the "Agreements") with an unrelated
company, now known as Arbios Systems, Inc. ("Arbios"). These Agreements, among
other aspects, resulted in Spectrum being granted 362,669 shares of Arbios.
Arbios became a public company on October 30, 2003 and is now listed on the OTC
Bulleting Board under the symbol of ABOS.OB. Arbios is an early-stage biomedical
device company engaged in the discovery, acquisition and development of
proprietary liver assist devices and new technologies useful in the diagnosis
and treatment of acute liver failure. In compliance with SFAS No. 115 based on
the listed trade price of $2.50 per share Spectrum allocated $907,000 as the
fair market value reflecting this amount as accumulated other comprehensive
income on its balance sheet as of December 27, 2003. The amount of the Arbios
investment was adjusted to $961,000 as of December 25, 2004, per the listed
trade quote of $2.65. Based on Arbios most recent trade price of $1.90, as of
September 23, 2005, Spectrum reflected a decrease in fair market value during
the first nine months of 2005 of $272,000 to $689,000 on its balance sheet as of
September 24, 2005. Spectrum has classified this amount as a non current asset
as it realizes there have been limited trades in Arbios and the potential to
sell the stock may be limited. In addition, due to Arbios being an early stage
developmental company, this investment may be subject to significant
adjustments.

The Company is obligated under the terms of various operating lease agreements
for manufacturing, warehouse and office facilities. Certain of these leases
provide for rent escalation adjustments. Minimum future rental payments under
these operating lease agreements for the final quarter ending December 31, 2005
and the subsequent years ending December 31 are as follows: final quarter 2005
$113,000 and $106,000 year ending 2006 (total $219,000).

Subsequent Events

The Board of Directors of Spectrum elected on October 6, 2004 to amend its
Certificate of Incorporation to effect a 1 for 25,000 reverse stock split.
Stockholders, subsequent to the reverse stock split, holding fractional shares,
would be paid $2.56 per share for each pre reverse stock split share. The Board
of Directors then elected to effectuate a going private transaction, as
subsequent to the reverse stock split the Company anticipates it will only have
3 shareholders.

To effectuate the above transactions Spectrum filed a Schedule 14C Information
Statement with the Securities and Exchange Commission ("SEC") on October 12,
2004 and subsequently filed a number of amendments. A definitive Schedule 14C


                                       10

was filed on November 2, 2005. In addition the Company filed a Schedule 13E-3
Transaction Statement on October 13, 2004 with the latest amended Schedule
13E-3A being filed on October 25, 2005. The Company has recognized approximately
$115,000 in expense relating to going private, $50,000 in the nine months of
fiscal 2005 and $65,000 in fiscal 2004. Spectrum currently estimates it will
amend its Certificate of Incorporation in late November or early December of
2005 to effectuate the above discussed reverse stock split. Subsequently the
Company will file Form 15 with the SEC, to effectuate being a private company.

Item 3.  Controls and Procedures

As of the end of the period covered by this report, the Company conducted an
evaluation, under the supervision and with the participation of the principal
executive officer and principal financial officer, of the Company's disclosure
controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the
Securities Exchange Act of 1934 (the "Exchange Act")). Based on this evaluation,
the principal executive officer and principal financial officer concluded that
the Company's disclosure controls and procedures are effective to ensure that
information required to be disclosed by the Company in reports that it files or
submits under the Exchange Act is recorded, processed, summarized and reported
within the time periods specified in Securities and Exchange Commission rules
and forms. There was no change in the Company's internal control over financial
reporting during the Company's most recently completed fiscal quarter that has
materially affected, or is reasonably likely to materially affect, the Company's
internal control over financial reporting.
