Voting Agreement

This Agreement is entered into as of October 19, 2002 by Stericycle, Inc., a Delaware corporation ("Parent"), Sharps Acquisition Corporation, a Delaware corporation and wholly owned subsidiary of Parent ("MergerSub"), and Robert P. Scherer, Jr., a Georgia resident ("Stockholder").

Background:

A. Stockholder is a significant stockholder of Scherer Healthcare, Inc., a Delaware corporation ("Company"). He directly owns 493,983 shares of Company Common Stock, par value $0.01 per share (the "Direct Shares"), and is the sole stockholder, director and officer of RPS Investments, Inc. ("Holding Company"), which owns 1,224,235.5 shares of Company Common Stock (the "Indirect Shares").

B. In addition, Stockholder is the sole trustee of a voting trust for the benefit of his adult children (the "Voting Trust"), which was established under that certain Voting Trust Agreement, dated February 23, 1997, by and among Robert P. Scherer, III, Lesley E. Scherer Reeves, Stephen M. Scherer and Mark C. Scherer and which owns 562,739.5 shares of Company Common Stock (the "Voting Trust Shares"). Stockholder is also a co-trustee, with shared voting power, of a trust (the "Irrevocable Trust"), which owns 340,212 shares of Company Common Stock (the "Irrevocable Trust Shares").

C. The Direct Shares, the Indirect Shares, the Voting Trust Shares and the Irrevocable Trust Shares together represent approximately 60% of the 4,390,264 shares of Company Common Stock issued and outstanding as of the date of this Agreement.

D. Concurrently with the execution of this Agreement, Parent, MergerSub and Company have entered into an Agreement and Plan of Merger, dated October 19, 2002 (the "Merger Agreement"), pursuant to which Parent will acquire all of Company's outstanding capital stock for cash through a merger of Company with MergerSub (the "Merger").

E. Company's board of directors, based upon the unanimous recommendation of a special committee of its board of directors, has resolved to recommend that Company's stockholders of Company approve the Merger Agreement and the consummation of the Merger.

F. Parent and MergerSub would not have entered into the Merger Agreement without the voting and other assurances provided by Stockholder in this Agreement.

Now, therefore, in consideration of their mutual promises, and intending to be legally bound, the parties agree as follows:

1. Definitions

Capitalized terms used in this Agreement (including the preceding background paragraphs) without being defined have the same meanings that they have in the Merger Agreement.

3. Transfers

During the term of this Agreement, Stockholder shall not sell, transfer or otherwise encumber ("Transfer") ownership or control of any of the Direct Shares, or permit the Holding Company to Transfer ownership or control of any of the Indirect Shares, otherwise than in accordance with the terms of the Merger, unless Stockholder first provides Notice to Parent and MergerSub of the proposed Transfer and delivers to Parent and MergerSub, prior to or concurrently with the proposed Transfer and in form acceptable to Parent and MergerSub, the written agreement of the proposed transferee to be bound by the terms of this Agreement in respect of the Direct or Indirect Shares transferred.

During the term of this Agreement, but subject in all cases to any fiduciary or similar duties, obligations or laws relating to Stockholder's status as a trustee, if the Voting Trust authorizes Stockholder, as the sole trustee, to Transfer Voting Trust Shares, Stockholder shall not exercise this authority, otherwise than in accordance with the terms of the Merger, unless Stockholder first provides Notice to Parent and MergerSub of the proposed Transfer and delivers to Parent and MergerSub, prior to or concurrently with the proposed Transfer and in form acceptable to Parent and MergerSub, the written agreement of the proposed transferee to be bound by the terms of this Agreement in respect of the Voting Trust Shares transferred.
