In case the Company shall issue any shares of its Common Stock as a stock dividend or subdivide the number of outstanding shares of Common Stock into a greater number of shares, then, in either of such cases, the Purchase Price Per Share in effect at the time of such action shall be proportionately reduced and the number of shares of Common Stock at that time purchasable pursuant to these Warrants shall be proportionately increased; and, conversely, in the event the Company shall contract the number of outstanding shares of Common Stock by combining such shares into a smaller number of shares, then, in such case, the Purchase Price Per Share in effect at the time of such action shall be proportionately increased and the number of shares of Common Stock at that time purchasable pursuant to these Warrants shall be proportionately decreased.

In case the Company shall consolidate or merge with or convey all or substantially all its property and assets to any other corporation or corporations, then as a condition of such consolidation, merger or conveyance, lawful and adequate provision shall be made in which the Holder shall have the right to purchase, upon the terms and conditions specified in these Warrants, in lieu of the shares of Common Stock previously purchasable upon the exercise of these Warrants, the kind and amount of shares of stock and other securities and property receivable upon such consolidation, merger or conveyance by a holder of the number of shares of Common Stock which the Holder might have purchased immediately prior to such consolidation, merger or conveyance. -2- 4. Whenever the Purchase Price Per Share or the kind or amount of securities purchasable under these Warrants shall be adjusted pursuant to any of the provisions of this certificate, the Company shall cause to be sent to the Holder by first-class mail at his address as it appears upon the records of the Company, a certificate setting forth the adjustments in the Purchase Price Per Share and/or in said number of shares, and also setting forth in detail the facts requiring such adjustments including, without limitation, a statement of the consideration received or deemed to have been received by the Company for any additional shares of stock issued by it. 5. The holder of these Warrants shall be entitled to those registration rights set forth in Exhibit G to that certain Asset Purchase Agreement dated February 28, 1992. 6. No fractional shares or scrip representing fractional shares shall be issued upon the exercise of these Warrants.

These Warrants shall not entitle the Holder to any voting rights or any other rights as a shareholder of the Company, or to any other rights except the rights stated in this certificate; and no dividend or interest shall be payable or shall accrue in respect of these Warrants or the shares purchasable hereunder unless, and until, and except to the extent that, these Warrants shall be exercised.
