INTRODUCTION

This Schedule 13E-3(A) Transaction Statement is being filed by Spectrum
Laboratories, Inc., a Delaware corporation, ("Spectrum" or the "Company") and by
Roy T. Eddleman, Tomas V. Girardi and Walter J. Lack, each of whom is a director
of Spectrum and collectively own 98.4% of the Company's common stock and relates
to a 1-for-25,000 reverse stock split of Spectrum's outstanding common stock.

The purpose of the reverse stock split is to decrease the total number of
Spectrum's Common Stockholders from approximately 450 to 3. By reducing the
number of stockholders below 300, Spectrum will be eligible to file a Form 15
with the Securities and Exchange Commission ("SEC") and terminate its
registration and reporting obligations under the Securities Exchange Act of
1934, as amended, (the "Exchange Act"). The going private transaction as
described herein, will enable Spectrum to save money being spent because of its
status as a reporting company, which Spectrum believes provides a limited
benefit to a small company like Spectrum.


The reverse stock split will be effected on or about May 30, 2005. The reverse
stock split was unanimously approved by Spectrum's Board of Directors at a
meeting held on October 6, 2004. The holders of 98.4% of the Company's stock on
written consent have approved this transaction. No additional consent is
required from stockholders. The reverse stock split is being effected with the
specific intent to reduce the number of stockholders of Spectrum's common stock
to a level where Spectrum is no longer obligated to file reports under the
Exchange Act.
