Sullivan Living Trust, dated September 6, 1978 ("TPS Trust"); Ann L. Sullivan Living Trust dated September 6, 1978 ("ALS Trust"); Thomas P. Sullivan; and Ann L. Sullivan, entered into a Stock Purchase Agreement ("Chem-Con Stock Purchase Agreement") and the Company, Chem-Met Services, Inc. ("Chem-Met"), the TPS Trust, the ALS Trust, TPS and ALS entered into a Stock Purchase Agreement ("Chem-Met Stock Purchase Agreement"). Under the terms of the Chem-Con Stock Purchase Agreement and the Chem-Met Stock Purchase Agreement (collectively, the "Stock Purchase Agreements"), the Company purchased all of the outstanding capital stock of Chemical Florida and Chemical Georgia from the ALS Trust and all of the outstanding capital stock of Chem-Met from the TPS Trust. The above-described transaction closed on June 2, 1999. Under the terms of the Stock Purchase Agreements, the purchase price paid by the Company in connection with the acquisition of Chemical Florida, Chemical Georgia and Chem-Met was $8,700,000, consisting of (i) $1,000,000 in cash paid at closing, (ii) three promissory notes ("Promissory Notes"), in the aggregate amount of $4,700,000, to be paid in equal monthly installments of principal and interest of approximately $90,276.96 over five years and having an interest rate of 5.5% for the first three years and 7% for the remaining two years, with payment of such Promissory Notes being guaranteed by Chem-Met under a non-recourse guaranty, which non- recourse guaranty is secured by certain real estate owned by Chem-Met, and (iii) $3,000,000 paid in the form of 1,500,000 shares of Common Stock, paid to the ALS Trust at closing; however, if the ALS Trust owns any of such shares of Common Stock at the end of eighteen (18) months from the June 2, 1999, closing date (the "Guarantee Period") and the market value (as determined below) per share of Common stock at the end of the Guarantee Period is less than $2.00 per share, the Company shall pay the ALS Trust, within then (10) business days after the end of the Guarantee Period, an amount equal to the sum determined by multiplying the number of shares of Common Stock issued to the ALS Trust under the Stock Purchase Agreements that are still owned by the ALS Trust at the end of the Guarantee Period by $2.00 less the market value (as determined below) of such shares of Common Stock owned by the ALS Trust at the end of the Guarantee Period, with such amount, if any, payable by the Company to the ALS Trust, at the Company's option, in cash or in Common Stock or a combination thereof. Notwithstanding anything to the contrary, the aggregate number of shares of Common Stock issued or issuable under the Stock Purchase Agreements for any reason whatsoever shall not exceed eighteen percent (18%) of the number of issued and outstanding shares of Common Stock on the date Page 6 of 10 CUSIP NO. 714157-10-4 ______________________ immediately preceding the June 2, 1999, closing date.

Under the Company's loan agreement, the Company may only pay any such amount due the ALS Trust at the end of the Guarantee Period in Common Stock unless the lender agrees that the Company may satisfy all or part of such in cash.
