Licensee guarantees the payment by each assignee or sublicensee of Licensee of all payments which become due or payable to Licensor and all of Licensee's obligations hereunder shall continue during the Term hereof.

Licensor shall retain sole title in and to such Patents Rights originally licensed hereunder and such Improvement Patents, as Licensor shall have or does conceive, the rights under which shall be governed by this License Agreement. 14 (B) Licensee shall bear the cost of obtaining and maintaining (and shall maintain) Improvement Patents for inventions conceived by Licensee and present and past Affiliate employees. Licensee shall retain sole title in and to any Improvement Patents conceived by Licensee and present and past Affiliate employees. (C) Licensee shall bear the cost of obtaining and maintaining (and shall maintain) Improvement Patents conceived jointly by Licensor and Licensee, and title thereto shall be held jointly by Licensor and Licensee. The rights under any jointly developed Improvement Patents shall be governed by this License Agreement. (D) The obtaining and maintaining of patent positions and/or copyright and/or trademark registration or protection on each Licensed Product and in each country by Licensee, together with related costs, as set forth in subsections (A), (B) and (C) hereinabove shall be within the sole discretion of Licensee except as to original patent patent positions relating to the Patent Rights. Prior to or at the quarterly Owner's Committee as described in the letter from NGVSI to Licensor, Licensor and Licensee will each inform the other of all new potential patent related developments of the Licensed Products. Either Licensor or Licensee may call for the obtaining and maintaining of patent protection in connection with any such development, and Licensor and Licensee shall then proceed as agreed. The abandonment of maintenance of patent positions may be discussed and agreed to by Licensor and Licensee. If the parties do not agree on a course of conduct, for a period of 30 days after which meeting, either Licensor or Licensee; (i) can call for mediation and proceed with mediation if both Licensor and Licensee agree on mediation, or (ii) if there is no such agreement on mediation, either Licensor or Licensee may demand arbitration. If the arbitrator concludes that Licensee should not be required to obtain and maintain a patent at that time, unless mutually agreed between Licensor and Licensee, the subject matter may not be brought up again for one year. If the arbitrator concludes that the Patent Protection should be obtained and maintained as to a specific country or countries or otherwise, Licensee shall have the sole discretion as to whether or not it should obtain and maintain such protection. Should Licensee decide not to obtain patent protection and/or copyright and/or trademark registration or protection on a particular Licensed Product in any specific country at its own expense, then Licensor can obtain such patent protection and/or copyright and/or trademark registration or protection in Licensor's own name and expense and license others in such country with respect to such patent; provided, however, that Licensor shall first give written notice to the Licensee, that Licensor intends to exercise the rights afforded in the preceding clause of this sentence, whereupon the Licensee shall 15 have 60 days after receipt of said notice to perform its duties set forth above and upon the Licensee performing said duties, Licensor's rights under the preceding clause of this sentence shall be nullified and rendered void. If Licensee fails to perform within said time period, then all such rights (including the right to license such Licensed Products in such country) with reference to the patent position(s) of such Licensed Products shall revert to Licensor. (E) All employees or independent contractors of Caithness/NCF have been and those of Licensee have been, are and shall be required to execute and perform under a form of appropriate intellectual property and confidentiality agreement, as a condition of employment or engagement, in form and substance (from and after the Effective Date) satisfactory to Licensor and Licensee. (F) All references to Licensor in this Article IX shall be deemed to include Fawley and NCF except as Fawley may otherwise disclose by notice to Licensee. (G) In the event during the Term of this License Agreement, Licensee or any Affiliate incurs expenses in filing, maintaining or prosecuting Licensed Patents in the United States of America all such expenses shall be reimbursed by GRI pursuant to the Licensing Agreement shall belong to and be received by Licensee. In the event during the Term of this License Agreement, Licensee incurs expenses in filing, maintaining or prosecuting such Licensed Patents outside the United States of America, any contribution required to be made by GRI with respect thereto pursuant to Article II of the Licensing Agreement shall belong to and be received by Licensee.

Exhibit 2.2(B) POTENTIAL DISPUTE There is a potential dispute between NCF and Swiss Aluminum Ltd. ("Alusuisse") of Zurich, Switzerland with respect to certain of the NCF Technology. In late 1980 Alusuisse invited Fawley to make a presentation of the NCF Technology to its technical staff in Zurich for the purpose of entering into either a joint venture between Fawley and Alusuisse or long-term exclusive license agreement to be granted Alusuisse by Fawley. During three of four days of presentation Fawley discussed and disclosed proprietary NCF Technology with and to Alusuisse personnel. Following said meeting, by letter dated January 22, 1981, Alusuisse informed Fawley that Alusuisse had filed a patent position in mid-1980 regarding fiber reinforced cylinders and suggested that Fawley simply consult for Alusuisse and that Fawley would be offered some undefined equity position in an Alusuisse company producing fiber reinforced vessels. A copy of the letter from Alusuisse dated January 22, 1981, the responses from Fine, Perzik & Friedman, attorneys for Fawley and NCF, dated April 10, 1981 and July 31, 1981, and the responding letter from Alusuisse dated November 17, 1981 have been provided Caithness by NCF.
