Mr. Liddle acknowledges that performance of his duties may require frequent travel and/or extended periods away from his office and that his office may be relocated for appropriate business reasons at the direction of the Companies Board of Directors. V. DUTIES AND RESPONSIBILITIES A. Mr. Liddle agrees to devote his entire professional time, energy, and ability to the proper and efficient performance of professional services for the Companies and their Operating Affiliates. Without the prior express written authorization of the Companies, Mr. Liddle shall not, directly or indirectly, during his employment with the Companies render services of a professional nature to any other person or firm, whether for compensation or otherwise. B. During the Term and for a period of three (3) years thereafter, Mr. Liddle shall not, without the written consent of the Board of Directors or a person authorized by the Board of Directors, disclose to any person other than as required by law or court order, or other than to an authorized employee of the Companies or its affiliates, or to a person to whom disclosure is necessary or appropriate in connection with the performance by Mr. Liddle of his duties as an executive of the Companies (e.g., disclosure to the Companies or its affiliates' outside accountants or bankers of financial data properly requested by such persons and approved by an authorized officer of the Companies), any confidential information obtained by him while in the employ of the Companies with respect to the Companies or their affiliates', including confidential information regarding any of the Companies' or their affiliates' business opportunities or projects (collectively "Projects"); provided, however, that confidential information shall not include any information known generally to the public (other than as a result of unauthorized disclosure by Mr. Liddle). Mr. Liddle shall be allowed to disclose confidential information to his attorney solely for the purpose of ascertaining whether such information is confidential within the intent of this Agreement; provided, however, that Mr. Liddle (a) discloses to his attorney the provisions of this subsection B and (b) agrees not to waive the attorney- client privilege with respect thereto. C. While Mr. Liddle is employed by the Companies, he shall make available to the Companies business opportunities that come to his attention or to the attention of persons (other than natural persons) under his control, and shall promptly provide to the Chief Operating Officer of the Companies all material facts regarding such opportunities. D. During the Term and for a one-year period following the termination of the Term, Mr. Liddle agrees that he shall not compete with the Companies or any of their affiliates without the prior written consent of the Board of Directors. For purposes of this Agreement, the term "compete" shall mean participating as a more than five (5%) stockholder, an officer, a director, an employee, a partner, an agent, a consultant, or in any other individual or representative capacity in any business entity engaged in the business of consulting with respect to, developing, designing, or constructing waste disposal facilities within North America and/or the Caribbean. During the Term and for a period of two years following termination of the Term, Mr. Liddle shall not engage in any Prohibited Solicitation. For purposes of this Agreement, the term "Prohibited Solicitation" shall mean (i) contacting directly or indirectly regarding any business relating to waste disposal and;/or power generation any potential customer (a) to which the Companies or any of their affiliates made a proposal during the Term, (b) which issued to the Companies, or disclosed to the Companies, plans to issue, during the Term, any request for proposal or invitation for bids regarding waste disposal facilities or, (c) about which a prospective project was reported or advertised during the Term in either of the trade publications The Resource Recovery Report or Sludge, and regarding which, with respect to (A) or (B) above, the Companies notifies Mr. Liddle of its intent to propose or bid, or (ii) employing or soliciting for employment any employees of the Companies or any of their affiliates. In the event the restrictions against engaging in a competitive activity or Prohibited Solicitation contained in this subsection D shall be determined by any court of competent jurisdiction to be unenforceable by reason of their extending for too great a period of time or over too great a geographical area or by reason of their being too extensive in any other respect, this subsection D shall be interpreted to extend only over the maximum period of time for which it may be enforceable and over the maximum geographical area as to which it may be enforceable and to the maximum extent in all other respects as to which it may be enforceable, all as determined by such court in such action. Mr. Liddle acknowledges that a breach of the restrictions against engaging in a competitive activity or Prohibited Solicitation contained in this subsection D may cause irreparable damage to the Companies or their affiliates, the exact amount of which will be difficult to ascertain, and that the remedies at law for any such breach may be inadequate. Accordingly, Mr. Liddle and the Companies agree that if he breaches the restrictions against engaging in a competitive activity or Prohibited Solicitation contained in this subsection D, in addition to any other remedies to which it or they may be entitled, then the Companies or their affiliates shall be entitled to equitable relief, including but not limited to injunctive relief, without posting bond or other security. VI. COMPENSATION A. Mr. Liddle shall be compensated by the Companies with an annual base salary payable semi-monthly ("Annual Base Salary"). Initially, the Annual Base Salary payable to Mr. Liddle shall be $110,000. Increases in the Annual Base Salary shall be considered from time to time by the Board of Directors. B. Mr. Liddle shall receive a financing bonus ("Project Financing Bonus") and a completion bonus ("Project Completion Bonus") of $5,000 and $15,000, respectively, per each processing line of Thermoselect, Noell or similar technology to be installed in a facility in which the Companies or any Operating Affiliate has at least a 50% equity interest or a lesser equity interest approved by the Companies' Board of Directors. Mr. Liddle shall be entitled to receive a Project Financing Bonus upon closing by the Companies or an Operating Affiliate of financing adequate to complete the project either during (i) the Term of this agreement, or (ii) within three (3) years following expiration or termination of the Term with respect to any facility for which the Companies or any Operating Affiliate has presented a definitive proposal during the Term. Mr. Liddle shall be ertitled to receive a Project Completion Bonus when each processing line becomes operational and accepted by the customer either during (i) the Term, or (ii) within three (3) years following the expiration or termination of the Term with respect to any facility for which the Companies or an Operating Affiliate has presented a definitive proposal during the Term. Each Project Completion Bonus shall become due and payable when each such processing line becomes operational and accepted by the customer. C. The Companies hereby transfer to Mr. Liddle 10,000 shares of the common stock of each of IWT and CWT ("Founders' Shares"). The total number of all shares outstanding of each of which companies shall initially be 1,000,000 shares; provided however, that Mr. Liddle shall forfeit (i) 80% of such Founders' Shares if Mr. Liddle terminates his employment or is terminated for any cause after the first anniversary but prior to the second anniversary of the date of this Agreement; (ii) 60% of such Founders' Shares if Mr. Liddle terminates his employment or is terminated for any reason after the second anniversary but prior to the third anniversary of the date of this Agreement; (iii) 40% of such Founders' Shares if Mr. Liddle terminates his employment or is terminated for any reason after the third anniversary but prior to the fourth anniversary of the date of this Agreement; (iv) 20% of such Founders' Shares if Mr. Liddle terminates his employment or is terminated for any reason after the fourth anniversary but prior to the fifth anniversary of the date of this Agreement; provided further that if Mr. Liddle is terminated due to death or disability, IWT and CWT shall transfer to Mr. Liddle or to his beneficiaries, in addition to such Founders' Shares that Mr. Liddle would otherwise retain upon termination of his employment, 1,500 shares of the outstanding common stock of each of IWT and CWT, respectively. Beginning on the date of this Agreement, Mr. Liddle shall be entitled to all dividends paid and any voting rights in respect of the Founders' Shares. Mr. Liddle shall also be entitled to liquidation proceeds, if any, with respect to such Founders' Shares as are not subject to forfeiture pursuant to this Section. Any Founders' Shares transferred hereunder shall not be transferable if such Founders' Shares are subject to forfeiture pursuant to this section. The foregoing section shall not apply to a transfer that is part of a transaction whereby substantially all of the assets or stock of IWT or CWT, as the case may be, is sold or otherwise transferred to an unrelated third party, unrelated meaning an entity not controlled by a party to this Agreement or by Mr. James J. Wilson and/or his family. Any shares of CWT and/or IWT held in trust for the benefit of the unitholders from time to time of IGC shall not be subject to a provision in that the trust instrument requiring that at such time as the Trustees determine that the ecomonic performance of IWT and CWT is sufficient to create a viable market for the common stock of such company, the Trustees shall consider the advisability of distributing the shares of such company then held in trust to IGC unitholders. At such time as a portion of the shares of IWT or CWT held by the Trust are sold, Mr. Liddle shall have the right to sell the same proportion of his shares by the same purshaser(s) as are being sold by the Trust and on the same terms. D. Mr. Liddle hereby represents and warrants that he is acquiring the Founders' Shares for investment for his own account and not with a view to, or for resale in connection with the distribution or other disposition thereof. Mr. Liddle agrees and acknowledges that he will not, directly or indirectly, offer, transfer, sell, assign, pledge, hypothecate or otherwise dispose of any shares of the Founders' Shares unless such transfer, sale, assignment, pledge, hypothecation or other disposition (i) is pursuant to an effective registration statement under the Securities Act of 1933 and the rules and regulations in effect thereunder (the "Act") and under all applicable state securities laws, or (ii) Mr. Liddle shall have furnished the issuer with an opinion of counsel, which opinion and counsel shall be satisfactory to the issuer, to the effect that no such registration is required because of the availability of an exemption from registration under the Act and under all applicable state securities laws. E. Mr. Liddle acknowledges that he has been advised by each of IWT and CWT that (i) the Founders' Shares have not been registered under the Act; (ii) the Founders' Shares must be held indefinitely and Mr. Liddle must continue to bear the economic risk of the investment in the Founders' Shares unless the offer and sale of such shares is subsequently registered under the Act and all applicable state securities laws or an exemption from registration is available; (iii) it is not anticipated that there will be any public market for the Founders' Shares in the foreseeable future; (iv) Rule 144 promulgated under the Act is not presently available with respect to the sales of any securities of IWT or CWT, and neither IWT nor CWT has made a covenant to make such rule available; (v) when and if the Founders' Shares may be disposed of without registration under the Act in reliance on Rule 144, such disposition can be made only in limited amounts in accordance with the terms and conditions of such Rule; (vi) if the Rule 144 exemption is not available, public offer or sale without registration will require the availability of an exemption under the Act; (vii) a restrictive legend substantially in the form set forth in Paragraph F. of this Section VI shall be placed on the certificates representing the Founders' Shares; and (viii) a notation shall be made in the appropriate records of each of IWT and CWT indicating that the Founders' Shares are subject to restriction on transfer and, if the issuer shall at some time in the future engage the services of a stock transfer agent, appropriate stop transfer restrictions will be issued to such transfer agent with respect to the Founders' Shares. F. If any of the Founders' Shares are to be disposed of in accordance with Rule 144 under the Act or otherwise, Mr. Liddle shall promptly notify the issuer of such Founders' Shares of the intended disposition and shall deliver to the issuer at or prior to the time of such disposition such documentation as the issuer may reasonably request in connection with such disposition and, in the case of a disposition pursuant to Rule 144, shall deliver to the issuer an executed copy of any notice on Form 144 required to be filed with the Securities and Exchange Commission. Mr. Liddle agrees that, if any securities of IWT or CWT are offered to the public pursuant to an effective registration statement under the Act, Mr. Liddle will not without the consent of the issuer effect any public sale or distribution to the Founders' Shares not covered by such registration statement within seven (7) days prior to, or within ninety (90) days after, the effective date of such registration statement. Mr. Liddle is aware that the Founders' Shares shall bear a legend in substantially the following form: THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), OR ANY STATE SECURITIES LAWS (THE "LAWS"), AND MAY NOT BE SOLD, TRANSFERRED, ASSIGNED, PLEDGED, OR OTHERWISE DISPOSED OF EXCEPT PURSUANT TO AN OPINIONOF COUNSEL SATISFACTORY TO THE COMPANY THAT IT MAY BE TRANSFERRED IN COMPLIANCE WITH THE ACT AND THE LAWS. G. On each occasion, if any, followingthe Effective Date, that either IWT or CWT contemplates filing with the SEC a registration statement under the Act relating in whole or in part to the primary offer and sale of shares of its common stock or common stock equivalent, other than a registration statement which relates exclusively to the registration of securities under an employee stock option, bonus, retirement or other compensation plan or solely to the issuance of securities in connection with a business acquisition or combination, IWT or CWT, as the case may be, shall notify Mr. Liddle in writin of its intention to do so at least thirty (30) days prior to the filing of each such registration statement. If Mr. Liddle gives written notice to IWT or CWT, as the case may be, within fifteen (15) days of receipt of such notice from IWT or CWT, as the case may be, of Mr. Liddle's desire to have any of his Founders' Shares included in such registration statement, then Mr. Liddle may, subject to the provisions of this Section VI.(G.) have his Founders' Share so included. IWT or CWT, as the case may be, shall file any required amendments of or supplements to any registration statement filed pursuant to this Section VI.(G.). IWT or CWT, as the case may be, shall bear all expenses in connection with the registration statement. Notwithstanding the foregoing, if the underwriter of any such offering determines that the number of shares proposed to be sold by IWT or CWT, as the case may be and/or by Mr. Liddle is greater than the number of shares which the underwriter believes feasible to sell at that time, at the price and upon the terms approved by IWT or CWT, as the case may be, then the number of shares which the underwriter believes may be sold shall be allocated in the following order: (i) primary shares being offered by IWT or CWT, as the case may be, and (ii) pro rate, between the Founders' shares owned by Mr. Liddle and the shares of any other shareholder of IWT or CWT, as the case may be, with rights generally similar to the rights provided to Mr. Liddle under this Section VI.(G.). VII. FRINGE BENEFITS In addition to the compensation as defined above, Mr. Liddle shall be entitled to the following fringe benefits: A.
