W I T N E S S E T H: WHEREAS, the Company proposes to acquire a number of companies in the industrial valve distribution and repair services business (the "Proposed Acquisitions") for various combinations of cash and common stock, par value $.001 per share, of the Company ("Common Stock") prior to or concurrently with the successful completion of an initial underwritten public offering of Common Stock by the Company (the "IPO" and, together with the Proposed Acquisitions, the "Transactions"); WHEREAS, the Company desires to obtain a commitment for up to $6,000,000 of financing to pay the fees and expenses of its legal counsel and independent public accountants, its organizational expenses and the various other expenses the Company expects to incur up to the time the Transactions close (the "Pre-IPO Expenses"); and WHEREAS, to June 9, 1997 Allwaste has advanced $2,128,935 (the "Previously Advanced Amount") to The Safe Seal Company, Inc., a Texas corporation ("SSI"), pursuant to the terms of a letter agreement dated September 18, 1996 (the "Letter Agreement") to cover Pre-IPO Expenses; NOW, THEREFORE, in consideration of the agreements and undertakings of the parties hereinafter set forth, and for other good and valuable consideration, the receipt and sufficiency of which the parties hereto hereby acknowledge, the parties hereto hereby agree as follows: 1. COMMITMENT. 1.1 ADVANCES. Subject to the terms and conditions of this Agreement, Allwaste agrees to make advances (the "Advances") to the Company from time to time between the date hereof and the Termination Date (as hereinafter defined) up to an aggregate principal amount of $6,000,000. The term "Termination Date" means the earliest to occur of (i) December 31, 1997, (ii) the date on which the Company first receives payment for the shares of Common Stock it sells in the IPO (the "IPO Closing Date"), (iii) the Abandonment Date (as defined in the Modification and Settlement Agreement dated as of May 9, 1997, as amended and restated as of August 15, 1997, by and among SSI, Allwaste and the other parties thereto) or (iv) the date Allwaste terminates its commitment hereunder pursuant to Section 7; provided, however, if the Company has filed a registration statement relating to the IPO under the Securities Act of 1933, as amended (the "Securities Act"), 1 on or before December 31, 1997 and is pursuing the IPO on December 31, 1997, the date referred to in clause (i) of this sentence will be the first to occur of (a) the date the Company withdraws that registration statement pursuant to Rule 477 under the Securities Act, (b) the date that registration statement is abandoned pursuant to Rule 479 under the Securities Act or (c) May 31, 1998. Allwaste also agrees to use commercially reasonable efforts to fund, on terms acceptable to the Company, the cash portion of the purchase price payable in each Proposed Acquisition that the Company effects prior to the IPO Closing Date, subject to Allwaste's covenants and other agreements with Philip Services Corp. Notwithstanding any provision hereof or of the Letter Agreement to the contrary, (i) the Previously Advanced Amount will be deemed for all purposes an Advance made under this Agreement on June 9, 1997 and (ii) on the execution and delivery of this Agreement by Allwaste, SSI will have no obligation to repay the Previously Advanced Amount or any interest that may have accrued thereon to Allwaste. 1.2 CONVERTIBLE PROMISSORY NOTE. When the Company executes and delivers this Agreement to Allwaste, the Company also will execute and deliver to Allwaste a Convertible Promissory Note in the form of Exhibit A (the "Note"). 1.3 PROCEDURE FOR ADVANCES. Monthly hereafter between the date hereof and the Termination Date, the Company may request an Advance hereunder by delivering to Allwaste a Request for Advance in substantially the form of Exhibit B, with the blanks therein appropriately filled. A Request for Advance may direct that the Advance be made to the Company or directly to such third parties as may be specified in the Request for Advance. Any amounts paid to third parties pursuant to such a direction in a Request for Advance shall be deemed to be made on behalf of the Company and, to the extent those amounts constitute expenses, those amounts will constitute expenses of the Company for all purposes and the Company shall be the owner of any and all benefits attributable to such expenses. Within five business days after Allwaste receives any Request for Advance from the Company, Allwaste will make the Advance requested thereby to the Company or to the Company's order as indicated in the Request for Advance. 1.4 CONVERSION AND REPAYMENT OF THE NOTE; PAYMENT OF OTHER OBLIGATIONS WITH COMMON STOCK. The Note will be subject to conversion and repayment in accordance with its terms. Allwaste agrees that the Company may, at its option exercisable on the IPO Closing Date, satisfy the payment obligations it owes to Allwaste on the IPO Closing Date, in an aggregate amount not to exceed the amount by which $10,000,000 exceeds the unpaid principal amount of the Note immediately before its conversion, with shares of Common Stock valued, for purposes of this Section 1.4, at the IPO Price (as defined in the Note). 1.5 INTEREST RATE. The Advances will bear interest at the annual rate per annum of 8%; provided, however, that on the occurrence and during the continuance of an Event of Default (as hereinafter defined), the Advances will bear interest at the rate of 10% per annum. Interest on the Note will be computed on the basis of a year of 365 or 366 days, as the case may be. 2 1.6 REGISTRATION RIGHTS.

LEGENDS AND RESTRICTIONS ON TRANSFER. 4.1 SECURITIES ACT LEGENDS. Each certificate or other document representing the Note and the shares of Common Stock issuable on conversion of the Note or pursuant to Section 1.4 (collectively the "Securities" and individually a "Security") will be stamped or otherwise imprinted with a restrictive legend in the form set forth in Exhibit A (in the case of the Note) or as follows (in the case of those shares): 5 THE SHARES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 AND MAY ONLY BE SOLD OR OTHERWISE TRANSFERRED IF THE HOLDER HEREOF COMPLIES WITH THAT LAW AND OTHER APPLICABLE SECURITIES LAWS. Except as provided in Section 4.2, if any Security is transferred or reissued, the certificates or other instruments representing it also will bear the appropriate legend prescribed above. 4.2 REMOVAL OF SECURITIES ACT LEGENDS. The Company will promptly deliver or cause to be delivered a new certificate or certificates or instrument or instruments representing any Security, which certificate or certificates or instrument or instruments will not bear the legends referred to or set forth in Section 4.1, when it determines (on the basis of such documentation as the Company reasonably requires, including an opinion of counsel) that the Security has been held beneficially by its holder for at least two years for purposes of Rule 144 under the Securities Act ("Rule 144") and that such holder is not and has not been within the preceding three months an affiliate of the Company. All determinations pursuant to the preceding sentence will be made in accordance with Rule 144(k) or any applicable successor rule.

Allwaste also agrees with the Company that the certificates evidencing the Common Stock issued on conversion of the Note or pursuant to Section 1.4 will bear a legend substantially in the form set forth below and containing such other information as the Company may deem necessary or appropriate: EXCEPT PURSUANT TO THE TERMS OF THE FUNDING AGREEMENT DATED AS OF JUNE 9, 1997 BETWEEN THE ISSUER AND THE HOLDER OF THIS CERTIFICATE, THE SHARES REPRESENTED BY THIS CERTIFICATE MAY NOT BE VOLUNTARILY SOLD, ASSIGNED, EXCHANGED, TRANSFERRED, ENCUMBERED, PLEDGED, DISTRIBUTED, APPOINTED OR OTHERWISE DISPOSED OF, AND THE ISSUER SHALL NOT BE REQUIRED TO GIVE EFFECT TO ANY ATTEMPTED VOLUNTARY SALE, ASSIGNMENT, EXCHANGE, TRANSFER, ENCUMBRANCE, PLEDGE, DISTRIBUTION, APPOINTMENT OR OTHER DISPOSITION OF ANY OF THOSE SHARES, DURING THE TWO-YEAR PERIOD ENDING ON __________ [DATE THAT IS THE SECOND ANNIVERSARY OF THE IPO CLOSING DATE.] 6 ON THE WRITTEN REQUEST OF THE HOLDER OF THIS CERTIFICATE, THE ISSUER AGREES TO REMOVE THIS RESTRICTIVE LEGEND (AND ANY STOP ORDER PLACED WITH THE TRANSFER AGENT) AFTER THE DATE SPECIFIED ABOVE. 5.

The Company will use its reasonable business efforts to enter into letters of intent and definitive agreements with leading industrial valve distribution or repair services companies and will keep Allwaste advised of the progress of its negotiations with the prospective sellers of those companies. The Company will not enter into any such definitive agreement unless it is (i) in material accordance with the valuation methodology previously discussed (or such other valuation methodology mutually agreed on by the Company and Allwaste) between the Company and Allwaste and (ii) approved by Allwaste. The Company will use its reasonable business efforts to close the Proposed Acquisitions of each such company simultaneously with the closing of the IPO. 5.3 IPO. The Company will use its reasonable business efforts to consummate the IPO as promptly as practicable. 5.4 ACCESS. The Company will provide to Allwaste and its counsel, accountants and other representatives access, at reasonable times during normal business hours, to all the properties, books and records, contracts and agreements and employees of the Company, so that Allwaste may have full opportunity to make such investigation as it desires to make of the business and assets of the Company and the companies to be acquired by the Company. 7 6. CONDITIONS TO ADVANCES. Allwaste will not be obligated to make any Advance unless it has received (i) the Note and the Registration Agreement, duly executed and delivered by the Company, (ii) resolutions of the Board of Directors of the Company, duly certified by the secretary of the Company, authorizing the execution, delivery and performance by the Company of this Agreement, the Note and the Registration Agreement, and (iii) the certificate of incorporation and bylaws, as amended to date, of the Company, duly certified by the secretary of the Company.

Each Request for Advance delivered to Allwaste will constitute the representation and warranty by the Company to Allwaste that the statements in clauses (ii), (iii) and (iv) in the preceding sentence are true and correct in all respects at the time of that delivery. 7. EVENTS OF DEFAULT. 7.1 EVENTS OF DEFAULT. For purposes of this Agreement, the occurrence of any one or more of the following events is an "Event of Default" (and the occurrence of an event that, but for the passage of time or the giving of notice or both, would be an Event of Default is a "Default"): (i) the failure of the Company to pay any amount due hereunder or under the Note when it becomes due and payable and the continuation of that failure for five days after written notice of nonpayment has been given to the Company by Allwaste; (ii) the failure of the Company to properly perform, observe and comply with any covenant contained in Section 5.1; (iii) the failure or refusal of the Company to punctually and properly perform, observe and comply with any covenant, agreement or condition contained in this Agreement, the Note or the Registration Agreement, other than the covenants referred to in clauses (i) and (ii) of this Section 7.1, and the continuation of that failure or refusal for 15 days after written notice of that failure or refusal has been given to the Company by Allwaste; (iv) the Company (a) voluntarily seeks, consents to or acquiesces in the benefit or benefits of any Debtor Relief Law (as hereinafter defined) or (b) becomes party to (or be made the subject of) any proceeding provided by any Debtor Relief Law, other than as a creditor or claimant, that could suspend or otherwise adversely affect the rights of Allwaste (or the then current holder of the Note) granted hereunder (unless in the event that proceeding is involuntary, the petition instituting the same is dismissed within 90 days of the 8 filing of same) (as used herein, the term "Debtor Relief Law" means the Bankruptcy Code of the United States of America and all other applicable liquidation, conservatorship, bankruptcy, moratorium, rearrangement, receivership, insolvency, reorganization or similar debtor relief laws from time to time in effect affecting the rights of creditors generally); or (v) any material representation or warranty made by the Company herein at any time proves to have been materially incorrect when made. 7.2 CONSEQUENCES. If an Event of Default described in Section 7.1(iv) exists, Allwaste's commitment to make Advances automatically will terminate and the entire unpaid balance of the Advances automatically will become due and payable without any action of any kind by Allwaste. If any other Default or Event of Default exists, Allwaste may do any one or more of the following: (i) declare the entire unpaid balance of all or any part of the Advances immediately due and payable; (ii) terminate its commitment to make Advances; (iii) reduce any claim to judgment; and (iv) exercise any and all other legal or equitable rights afforded by this Agreement or the Note or the laws of the State of Texas or any other applicable jurisdiction. The Company waives presentment and demand for payment, protest, notice of intention to accelerate, notice of acceleration and notice of protest and nonpayment. No waiver of a Default or an Event of Default by Allwaste will be deemed a waiver of any other then existing or subsequent Default or Event of Default. No delay or omission by Allwaste in exercising any right under this Agreement or the Note will impair that right or be construed as a waiver of that right, nor will any single partial exercise of any right preclude any other or further exercise of that or any other right. 8.
