After the Registration Statement, referenced in Section 4.4(a) hereinbelow, is declared effective by the Securities and Exchange Commission ("Commission"), or after any registration statement in which Investor Securities or Additional Shares (as hereinafter defined) are included pursuant to the registration rights set forth in Section 4.4(b) is declared effective by the Commission, the Investors may deliver to the Company the certificates representing the Investor Securities and/or Additional Shares so registered, and the Company will, within three days after receipt by the Company of the foregoing, cause its transfer agent to issue new certificates representing and in exchange for the aforementioned certificates, which new certificates shall be legended as follows: THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED.

The legend shall be removed by the Company from any certificate at such time as the holder of the shares represented by the certificate delivers an opinion of counsel reasonably satisfactory to the Company to the effect that such legend is not required in order to establish compliance with any provisions of the Act, or at such time as the holder of such shares satisfies the requirements of Rule 144(k) under the Act, provided that Rule 144(K) as then in effect does not differ substantially from Rule 144(k) as in effect as of the date of this Agreement, and provided further that the Company has received from the holder a written representation that (i) such holder is not an affiliate of the Company and has not been an affiliate during the preceding three (3) months, (ii) such holder has beneficially owned the shares represented by the certificate for a period of at least three (3) years or such other period of time then set forth under Rule 144(k),and (iii) such holder otherwise satisfies the requirements of Rule 144(k) as then in effect with respect to such shares. 4. COVENANTS OF THE COMPANY. The Company covenants and agrees as follows: 4.1. USE OF PROCEEDS. The Company will apply the proceeds received from the sale of the Common Stock for working capital and general corporate purposes. No proceeds of the Shares and Warrants sold to the Investors or the proceeds of any exercise of the Warrants in excess of $25,000 will be used to pay any debt for borrowed funds from any director or officer, or any debts or obligations owed to any officer, director or stockholder of the Company or any of their respective affiliates. 4.2. FINANCIAL STATEMENTS AND OTHER INFORMATION.

At such time, the person or persons in whose name or names any certificates for Warrant Shares shall be issuable upon such exercise as provided in subsection 1 (c) below shall be deemed to have become the holder or holders of record of the Warrant Shares represented by such certificates. (c) As soon as practicable after the exercise of the purchase right represented by this Warrant, the Company at its expense will use its best efforts to cause to be issued in the name of the Registered Holder and delivered to you: (i) a certificate or certificates for the number of full shares of Warrant Shares to which such Registered Holder shall be entitled upon such exercise plus, in lieu of any fractional share to which such Registered Holder would otherwise be entitled, a Warrant Share representing the remainder of the fractional share to the next whole Warrant Share, and (ii) in case such exercise is in part only, a new warrant or warrants (dated the date hereof) of like tenor, stating on the face or faces thereof the number of shares currently stated on the face of this Warrant minus the number of such shares purchased by the Registered Holder upon such exercise as provided in section 1(a) above. 2.

When any adjustment is required to be made in the Purchase Price, the number of shares of Warrant Shares purchasable upon the exercise of this Warrant shall be changed to the number determined by dividing (i) an amount equal to the number of shares issuable upon the exercise of this Warrant immediately prior to such adjustment, multiplied by the Purchase Price in effect immediately prior to such adjustment, by (ii) the Purchase Price in effect immediately after such adjustment. (b) RECLASSIFICATION, REORGANIZATION, CONSOLIDATION OR MERGER. In the case of any reclassification of the Common Stock or any reorganization, consolidation or merger of the Company with or into another corporation (other than a merger or reorganization with respect to which the Company is the continuing corporation and which does not result in any reclassification of the Common Stock), or a transfer of all or substantially all of the assets of the Company, or the payment of a liquidating distribution then, as part of any such reorganization, reclassification, consolidation, merger, sale or liquidating distribution, the Company shall arrange for the other party to the transaction to agree to, and lawful provision shall be made, so that the Registered Holder of this Warrant shall have the right thereafter to receive upon the exercise hereof (to the extent, if any, still exercisable), the kind and amount of shares of stock or other securities or property which such Registered Holder would have been entitled to receive if, immediately prior to any such reorganization, reclassification, consolidation, merger, sale or liquidating distribution, as the case may be, such Registered Holder had held the number of shares of Common Stock which were then purchasable upon the exercise of this Warrant. In any such case, appropriate adjustment (as reasonably determined by the Board of Directors of the Company) shall be made in the application of the provisions set forth herein with respect to the rights and interests thereafter of the Registered Holder of this Warrant such that the provisions set forth in this Section 2 (including provisions with respect to the Purchase Price) shall thereafter be applicable, as nearly as is reasonably practicable, in relation to any shares of stock or other securities or property thereafter deliverable upon the exercise of this Warrant. 3. LIMITATION ON SALES. Each holder of this arrant acknowledges that this Warrant and the Warrant Shares have not been registered under the Securities Act of 1933, as now in force or hereafter amended, or any successor legislation (the "Act"), and agrees not to sell, pledge, distribute, offer for sale, transfer or otherwise dispose of this Warrant or any Warrant Shares issued upon its exercise in the absence of (a) an effective registration statement under the Act as to this Warrant or such Warrant Shares and registration or qualification of this Warrant or such Warrant Shares under any applicable, Blue Sky or state securities law then in effect or (b) an opinion of counsel, satisfactory to the Company, that such registration and qualification are not required. Without limiting the generality of the foregoing, unless the offering and sale of the Warrant Shares to be issued upon the particular exercise of the Warrant shall have been effectively registered under the Act, the Company shall be under no obligation to issue the shares covered by such exercise unless and until the Registered Holder shall have executed an investment letter in form and substance satisfactory to the Company, including a warranty at the time of such exercise that it is acquiring such shares for its own account, and will not transfer the Warrant Shares unless pursuant to an effective and current registration statement under the Act or an exemption from the registration requirements of the Act and any other applicable restrictions, in which event the Registered Holder shall be bound by the provisions of a legend or legends to such effect which shall be endorsed upon the certificate(s) representing the Warrant Shares issued pursuant to such exercise.

(A Texas corporation) Waste Recovery, Inc., a Texas corporation (the "Company"), hereby certifies that for value received, GKN Securities Corp. or its registered assigns (the "Registered Holder"), residing at 61 Broadway, New York, New York 10006, is entitled, subject to the terms set forth below, to purchase from the Company, pursuant to this Warrant ("Warrant"), at any time or from time to time until December 26, 2000 ("Expiration Date"), 25,000 shares of Common Stock, no par value, of the Company ("Common Stock"), at a purchase price equal to $2.0625 per share of Common Stock. The number of shares of Common Stock purchasable upon exercise of this Warrant, and the purchase price per share, each as adjusted from time to time pursuant to the provisions of this Warrant, are hereinafter referred to as the "Warrant Shares" and the "Purchase Price," respectively. 1. EXERCISE. (a) This Warrant may be exercised by the Registered Holder, in whole or in part, by the surrender of this Warrant (with the Notice of Exercise Form attached hereto as Exhibit I duly executed by such Registered Holder) at the principal office of the Company, or at such other office or agency as the Company may designate, accompanied by payment in full, m lawful money of the United States, of an amount equal to the then applicable Purchase Price multiplied by the number of Warrant Shares then being purchased upon such exercise. (b) Each exercise of this Warrant shall be deemed to have been effected immediately prior to the close of business on the day on which this Warrant shall have been surrendered to the Company as provided in subsection 1 (a) above. At such time, the person or persons in whose name or names any certificates for Warrant Shares shall be issuable upon such exercise as provided in subsection 1 (c) below shall be deemed to have become the holder or holders of record of the Warrant Shares represented by such certificates. (c) As soon as practicable after the exercise of the purchase right represented by this Warrant, the Company at its expense will use its best efforts to cause to be issued in the name of the Registered Holder and delivered to you: (i) a certificate or certificates for the number of full shares of Warrant Shares to which such Registered Holder shall be entitled upon such exercise plus, in lieu of any fractional share to which such Registered Holder would otherwise be entitled, a Warrant Share representing the remainder of the fractional share to the next whole Warrant Share, and (ii) in case such exercise is in part only, a new warrant or warrants (dated the date hereof) of like tenor, stating on the face or faces thereof the number of shares currently stated on the face of this Warrant minus the number of such shares purchased by the Registered Holder upon such exercise as provided in subsection 1 (a) above. 2. ADJUSTMENTS. (a) SPLIT SUBDIVISION OR COMBINATION OF SHARES. If the outstanding shares of the Company's Common Stock at any time while this Warrant remains outstanding and unexpired shall be subdivided or split into a greater number of shares, or a dividend in Common Stock shall be paid in respect of Common Stock, or a similar change in the Company's capitalization occurs which affects the outstanding Common Stock, as a class, then the Purchase Price in effect immediately prior to such subdivision or at the record date of such dividend shall, simultaneously with the effectiveness of such subdivision or split or immediately after the record date of such dividend (as the case may be), be proportionately decreased. If the outstanding shares of Common Stock shall be combined or reverse-split into a smaller number of shares, the Purchase Price in effect immediately prior to such combination or reverse split shall, simultaneously with the effectiveness of such combination or reverse split, be proportionately increased. When any adjustment is required to be made in the Purchase Price, the number of shares of Warrant Shares purchasable upon the exercise of this Warrant shall be changed to the number determined by dividing (i) an amount equal to the number of shares issuable upon the exercise of this Warrant immediately prior to such adjustment, multiplied by the Purchase Price in effect immediately prior to such adjustment, by (ii) the Purchase Price in effect immediately after such adjustment. (b) RECLASSIFICATION, REORGANIZATION, CONSOLIDATION OR MERGER. In the case of any reclassification of the Common Stock or any reorganization, consolidation or merger of the Company with or into another corporation (other than a merger or reorganization with respect to which the Company is the continuing corporation and which does not result in any reclassification of the Common Stock), or a transfer of all or substantially all of the assets of the Company, or the payment of a liquidating distribution then, as part of any such reorganization, reclassification, consolidation, merger, sale or liquidating distribution, the Company shall arrange for the other party to the transaction to agree to, and lawful provision shall be made, so that the Registered Holder of this Warrant shall have the right thereafter to receive upon the exercise hereof (to the extent, if any, still exercisable), the kind and amount of shares of stock or other securities or property which such Registered Holder would have been entitled to receive if, immediately prior to any such reorganization, reclassification, consolidation, merger, sale or liquidating distribution, as the case may be, such Registered Holder had held the number of shares of Common Stock which were then purchasable upon the exercise of this Warrant. In any such case, appropriate adjustment (as reasonably determined by the Board of Directors of the Company) shall be made in the application of the provisions set forth herein with respect to the rights and interests thereafter of the Registered Holder of this Warrant such that the provisions set forth in this Section 2 (including provisions with respect to the Purchase Price) shall thereafter be applicable, as nearly as is reasonably practicable, in relation to any shares of stock or other securities or property thereafter deliverable upon the exercise of this Warrant. 3. LIMITATION ON SALES. Each holder of this Warrant acknowledges that this Warrant and the Warrant Shares have not been registered under the Securities Act of 1933, as now in force or hereafter amended, or any successor legislation (the "Act"), and agrees not to sell, pledge, distribute, offer for sale, transfer or otherwise dispose of this Warrant or any Warrant Shares issued upon its exercise in the absence of (a) an elective registration statement under the Act as to this Warrant or such Warrant Shares and registration or qualification of this Warrant or such Warrant Shares under any applicable Blue Sky or state securities law then in effect or (b) an opinion of counsel, satisfactory to the Company, that such registration and qualification are not required.

This opinion is delivered to you pursuant to Section 5 of the Common Stock and Warrant Purchase Agreement dated as of December 26, 1996 (the "Stock Purchase Agreement") between the Company and the Investors. Terms used herein which are defined in the Stock Purchase Agreement shall have the respective meanings set forth in the Stock Purchase Agreement, unless otherwise defined herein. In connection with this option, we have examined the following: A. Stock Purchase Agreement; and B. Form of Warrant for the Purchase of Common Stock of the Company (the "Warrant Agreement"). We have also examined such corporate records, instruments and other documents as we have deemed necessary to enable us to render the opinions expressed herein. As to matters of fact material to this opinion, we have relied upon (i) the representations and warranties of the parties contained in or made in connection with the Stock Purchase Agreement and (ii) certificates or other documents furnished by or on behalf of the Company and its officers. In addition, as to certain matters we have relied upon certificates or other communications or documents from various state authorities and public officials. We have assumed, without independent verification, the accuracy of such representations, warranties, certificates, communications and other documents and of the factual matters contained therein. In connection with our examination, we have assumed the genuineness of all signatures (except signatures of officers of the Company), the legal capacity of natural persons, the authenticity of all documents submitted to us as originals and the conformity to authentic original documents of all documents submitted to us as certified, conformed, reproduction or facsimile copies. We also have assumed, for purposes of the opinions expressed herein, that (i) all parties to the Stock Purchase Agreement (other than the Company) are validly existing and have the power and authority to enter into such documents and perform their respective obligations thereunder, (ii) the Stock Purchase Agreement has been duly authorized, executed and delivered by all parties thereto other than the Company, and (iii) the Stock Purchase Agreement constitutes the valid, binding and enforceable obligations of all parties thereto other than the Company. We are members of the State Bar of Texas. We do not express any opinion herein with respect to the law of any jurisdiction other than the State of Texas and applicable Federal law. You should be aware that we are not admitted to the practice of law in the State of New York. With your permission, we have assumed for purposes of rendering this opinion, without research or confirmation, that the relevant laws of the State of New York are identical to those of the State of Texas. Based on the foregoing and subject to the assumptions, qualifications, limitations and conditions set forth herein, we are of the opinion that: 1. The Company is a corporation duly organized, validly existing and in good standing under the laws of the State of Texas. Based solely on certificates from the Company and oral information from its corporate agent acting on behalf of the Company in such jurisdictions, the Company is duly qualified and licensed to do business as a foreign corporation in the states set forth on Schedule B to this opinion, and to our knowledge, such jurisdictions constitute all of the jurisdictions in which the Company owns or leases any real property or the character of its operations require such qualification or licensing, except where the failure to so qualify or be licensed would not have a material adverse effect on the business, operations or financial condition of the Company. 2. The Company has all requisite corporate power and authority under the laws of the state of its incorporation to own and operate its properties and to carry on its business as now conducted, and, to our knowledge, the Company has all necessary authorizations, approvals, orders, licenses, certificates and permits of and from any and all applicable governmental or regulatory officials and bodies to own or lease its properties and conduct its business and is and has been doing business in compliance with all such authorizations, approvals, orders, licenses, certificates and permits and all federal, state and local laws, rules and regulations. The Company has the corporate power and authority to execute, deliver and perform its obligations under the Stock Purchase Agreement and to carry out the transactions contemplated thereby, and all consents, authorizations, approvals and orders required in connection therewith have been obtained. 3. The execution, delivery and performance of the Stock Purchase Agreement and each of the Warrant Agreements have been duly authorized by all necessary corporate action on the part of the Company. The Stock Purchase Agreement and the Warrant Agreements have been duly executed and delivered by the Company and constitute the legally valid and binding obligations of the Company, enforceable against the Company in accordance with their respective terms. 4. The Securities have been duly authorized and, when issued and paid for, will be validly issued, fully paid and non-assessable and free from all liens and charges (other than liens and charges that may be created by or attributable to the holder thereof); the holders thereof are not and will not be subject to personal liability by reason of being such holders. The Securities are not and will not be subject to the preemptive rights of any holders of any security of the Company or, to our knowledge, similar contractual rights granted by the Company. When issued, the Warrants will constitute valid and binding obligations of the Company to issue and sell, upon exercise thereof and payment therefor, the number and type of securities of the Company called for thereby. 5. The execution, delivery and performance of the Stock Purchase Agreement and the issuance and sale by the Company to the Investors of the Common Stock and the Warrants in accordance with the Stock Purchase Agreement and the consummation of the transactions contemplated under the Stock Purchase Agreement will not (i) conflict with, result in a breach of, constitute a default or require any consent under, the Articles of Incorporation or Bylaws of the Company or any statute, rule or regulation binding on the Company, or, to our knowledge, any agreement, mortgage, deed of trust, note, indenture, contract or commitment or order, writ, judgment or decree to which the Company is a party or by which any of its properties or assets are bound, or (ii) to our knowledge, result in the creation of any lien upon any of the material properties or assets of the Company under any agreement, mortgage, deed of trust, note, indenture, contract or commitment. 6. No action by or filing with any domestic governmental authority, federal, state or local, is required in connection with (i) the execution, delivery and performance by the Company of the Stock Purchase Agreement and or (ii) the exercise by the Investors of any rights under the Stock Purchase Agreement or the Warrant Agreements, except (x) with respect to the registration under the Securities Act of 1933, as amended, and state securities or "blue sky" laws pursuant to registration rights granted pursuant to the Stock Purchase Agreement and (y) any filings required by the nature and extent of the ownership of the Securities by the Investors. This opinion is limited by, subject to, and based on the following assumptions, qualifications, limitations and conditions: (a) The enforceability of the obligations of the Company under the Stock Purchase Agreement and the Warrant Agreements is subject to (i) the effect of any applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance or similar laws affecting creditors' rights generally, (ii) the effect of general principles of equity (regardless of whether considered in proceedings in equity or at law) and (iii) certain limitations regarding rights to indemnification and contribution thereunder. (b) In connection with opinions expressed herein as being limited "to our knowledge" or "known to us" or containing similar qualifications, such opinions are based on the actual knowledge of our attorneys working on these or other matters for the Company, and we have made no independent investigations as to the accuracy or completeness of any representations, warranties, documents or other information, written or oral, made or furnished by or on behalf of any officer or representative of the Company. This opinion is limited to the matters expressly stated herein and no opinion is implied or may be implied beyond the matters expressly stated. This opinion is delivered on the express condition and assumption that the Investors and their counsel do not have any knowledge of any reason why any opinion expressed herein is not accurate in any material respect.
