ARTICLE 5-0 - TECHNICAL COOPERATION AND DEMONSTRATION 5.1. Because the Licensed Unit is the first demonstration unit for the AROMAX Process, Chevron Research will make available to South Hampton different services than it normally makes available to licensees of its fully commercialized technology. Chevron Research and South Hampton agree that certain obligations and responsibilities relating to the conversion, preparation, startup, and operation of the Licensed Unit shall be as follows: 1. Laboratory Work a. Chevron Research will conduct or have conducted, at its expense, all standard laboratory tests and analyses appropriate to support the Demonstration Run. In order to perform -8- <PAGE> 10 such analyses, Chevron Research may set up its own gas chromatographic equipment at the Refinery. Test results shall be Chevron Research Technical Information. b. To the extent pilot plant work is necessary or appropriate, in Chevron Research's opinion, to support the Demonstration Run, Chevron Research will perform pilot plant tests or have them performed, at its expense. Pilot plant results shall be Chevron Research Technical Information. 2. Engineering Support a. Process Engineering--Chevron Research will provide, at its expense, process engineering services required to prepare the Licensed Unit for start-up. Those process engineering services include preparing sulfur sorber and sulfur control catalyst reactor specifications, reviewing and evaluating existing Refinery equipment for suitability for the Demonstration Run and determining modifications that are necessary, preparing flow schemes for feed and product streams of the Licensed Unit, defining the plant configuration for the Demonstration Run, and preparing performance estimates. Chevron Research, upon request and upon reasonable notice from South Hampton, will prepare and furnish for South Hampton's use a Procedures Manual for the Licensed Unit. South Hampton shall be responsible for process -9- <PAGE> 11 engineering evaluations relating to the operation of the debutanizer column on the product streams from the Licensed Unit. b. Plant Cleanup for Sulfur Removal--Chevron Research will specify the procedures appropriate for cleaning the Licensed Unit and associated equipment and pipes before catalyst may be loaded and the unit started up. South Hampton will perform or have performed those cleanup procedures at its expense and under the supervision or guidance of Chevron Research. c. Plant operation--South Hampton will provide plant operators at its expense. Chevron Research will station or have stationed, at its expense, at least one engineer at the refinery during the first six weeks of the Demonstration Run covering plant cleanup, startup, and the initial phases of operation of the Licensed Unit. The Chevron engineer(s) will provide full shift assistance during the two week period following startup of the Licensed Unit. Full shift assistance will also be provided during the first regeneration of the first charge of AROMAX Process Catalyst to the Licensed Unit. Chevron Research will instruct South Hampton's employees at the Refinery in the operation of Licensed Units, including reasonable training, at times mutually agreeable to South Hampton and Chevron Research. d. Routine operation--Chevron Research will make available engineering assistance for normal operations and for -10- <PAGE> 12 emergencies from the San Francisco area or from the Port Arthur Refinery of Chevron U.S.A. Inc., as appropriate, for the Licensed Unit during the Demonstration Run. 3. Equipment a. Chevron Research will provide online sulfur measurement apparatus or equipment appropriate to monitor the sulfur content of the feed stream to the Licensed Unit during the Demonstration Run. At the end of the Demonstration Run, South Hampton may buy that online sulfur measurement equipment from Chevron Research at a price to be mutually agreed, taking into account depreciation of the equipment. b. Except for the online sulfur measurement equipment provided for by Section 5.1(3)(a), South Hampton will provide, at its expense, all equipment, including but not limited to reactor vessels, sulfur sorber and sulfur control vessels, sampling and monitoring equipment and associated piping, sampling ports and valves, and all process control equipment, appropriate to conduct the AROMAX Process in the Licensed Unit. South Hampton will bear the costs of installing any equipment, including online sulfur measurement apparatus, in the Licensed Unit. -11- <PAGE> 13 4. Catalysts and Sorbents a. Sulfur Sorbent--Chevron Research will provide the first charge of sulfur sorbent for use in the Demonstration Run. Chevron Research will retain ownership of that first charge and upon its deactivation will be responsible for proper disposal of it. South Hampton will provide all further sulfur sorbent charges necessary for the operation of the Licensed Unit at its expense. b. Sulfur Control Catalysts--Chevron Research will provide the first charge of each of the sulfur control catalysts to be installed for both the cleanup phase and the Demonstration Run in the Licensed Unit. Chevron Research shall retain all ownership rights in the catalysts, including catalyst bases and platinum and other metals deposited on the catalyst bases, and upon deactivation of the sulfur control catalysts will be responsible for proper disposal of them. South Hampton will provide all further sulfur control catalyst charges necessary for the operation of the Licensed Unit at its expense. c. AROMAX Catalyst--Chevron Research will provide the first charge of AROMAX Catalyst to be installed in the Licensed Unit ("First Charge"). Chevron Research shall retain all ownership rights in the First Charge, including catalyst base and platinum and other metals deposited on the catalyst base. -12- <PAGE> 14 Chevron Research expects that the First Charge will achieve a total service life in excess of nine months from startup through use of multiple regenerations. From time to time during the Demonstration Run, Chevron Research will estimate the length of the then current run of the First Charge and the length of the run immediately following the next regeneration of the First Charge. The total service life of the First Charge will end with the then current run when the estimated length for the run immediately following the next regeneration is one and one-half months or less, unless South Hampton elects to continue to use the First Charge. In the event South Hampton elects to continue to use the First Charge for a run that Chevron Research has estimated will be one and one-half months or less, the total service life of the First Charge shall end when South Hampton ceases using the First Charge. In the event the total service life of the First Charge is less than nine months from startup, a replacement charge of AROMAX Catalyst is recommended, and South Hampton elects to place a replacement charge of AROMAX Catalyst in the Licensed Unit, Chevron Research will provide one replacement charge at no cost to South Hampton. Chevron Research shall retain all ownership rights in the replacement charge of AROMAX Catalyst, including catalyst base and platinum and other metals deposited on the catalyst base. -13- <PAGE> 15 d. Except as provided in Section 5.1(4)(c), Chevron Research will make AROMAX Catalyst, sulfur control catalysts or sulfur sorbents available to South Hampton pursuant to catalyst supply contracts containing Chevron Research's standard commercial terms and conditions if South Hampton wishes to continue practicing the AROMAX Process in the Licensed Unit or South Hampton wishes to continue using sulfur sorbent or sulfur control catalysts after removal of the first charge of each. Except as provided in Section 5.l(4)(c), all costs relating to all catalyst charges after the first, including metals recovery and disposal, will be for South Hampton's account. Upon request, Chevron Research will assist South Hampton in locating a source of metals for such further charges. 5. Refinery integration a. Feeds and Utilities--South Hampton will provide all feeds and utilities, including nitrogen gas and electrolytic hydrogen for the cleanup, startup, and regeneration phases of the demonstration, at its expense. b. Hydrogen--The unit being converted produces hydrogen gas that is supplied to other units at the Refinery. During the plant cleanup and startup phases of the demonstration, South Hampton will arrange for a hydrogen source to supply all hydrogen requirements of its other units at the Refinery at its expense. -14- <PAGE> 16 In the event of either a process failure of the AROMAX Process after startup of the Licensed Unit so that the Licensed Unit does not produce hydrogen (a need to regenerate AROMAX Catalyst is not a process failure) or a delay in startup beyond two weeks after commencement of plant cleanup, such delay being caused in Chevron Research's opinion by inadequate plant cleanup even though Chevron Research plant cleanup instructions are followed, Chevron Research shall arrange for hydrogen to be provided to the Refinery until the unit resumes hydrogen production. Notwithstanding the foregoing, Chevron Research's total liability in the event of such a process failure (a need to regenerate AROMAX Catalyst is not a process failure) or delay, including the cost of hydrogen provided, shall not exceed the greater of either Thirty-five Thousand Dollars ($35,000) or an amount agreed to in writing by an officer of Chevron Research. Chevron Research shall keep South Hampton informed of the amounts of costs applied against said total liability of Chevron Research. 6. Visitation rights a. At any time following execution of this Agreement, Chevron Research may, at its election, announce to the trade that South Hampton is an AROMAX Process licensee. South Hampton grants to Chevron Research and its representatives, visitors, customers, and nominees the right of access to the Licensed Unit during normal business hours for a period ending either five -15- <PAGE> 17 years after startup of the Licensed Unit or upon conversion of the unit to a process other than the AROMAX Process, whichever occurs first. South Hampton may limit such visits to a maximum of two per calendar month, may require Chevron Research personnel to accompany any such visitors, and may require any such visitors to enter into a secrecy agreement appropriate to protect South Hampton's proprietary information used at the Refinery. 7. Second unit license During the term of this Agreement, Chevron Research agrees that upon written request by South Hampton, Chevron Research shall grant South Hampton an AROMAX Process license so that South Hampton's 4,000 BPOD catalytic reforming unit located at the Refinery may be a licensed AROMAX Process unit. Chevron Research and South Hampton agree that AROMAX Process royalty rates charged to South Hampton for that unit, whether running or fully paid royalty rates, shall be based on Chevron Research's then current AROMAX Process royalty rates as follows: Royalty rate: % of then Barrels/Calendar Day current AROMAX Process rate -------------------- --------------------------- 0 - 1,000 0% 1,001 - 20000 50 2,001 - 3,000 75 over 3,000 100 -16- <PAGE> 18 ARTICLE 6-0 - CHARGES AND PAYMENTS 6.1 Except as provided by Article 5-0 above, South Hampton shall pay Chevron Research for all work and services, including pilot plant tests (if any), performed for South Hampton pursuant to this Agreement or as otherwise mutually agreed. South Hampton shall, within thirty (30) days after submission of Chevron Research's invoices therefor, pay to Chevron Research a sum equal to the cost of all work and services performed by Chevron Research during each calendar month plus an amount to equal twenty percent (20%) of the cost invoiced to allow Chevron Research to recover costs incurred but not billed. Included in the determination of such cost, but not by way of limitation, shall be: all direct expenses such as blueprints, computer usage, engineering and drafting supplies, analytical services, postage and shipping, telegraph, telephone, transportation and living expenses of Chevron Research's employees while engaged in services rendered at points other than at Chevron Research's home office or laboratories, and all similar expenses directly incurred in connection with such work and services; the salaries or wages allocated for the actual time of Chevron Research's employees engaged in such work and services; and an amount in respect of Chevron Research's overhead and indirect expenses that shall be determined as a percentage of such salaries and wages, such percentage to be the same as that applied by Chevron -17- <PAGE> 19 Research for similar services being performed at the time in question by Chevron Research for others under similar conditions and on substantially the same terms as this agreement. All charges and payments specified herein refer to lawful money of the United States and all payments to be made by South Hampton hereunder shall be paid to Chevron Research at the office of Chevron Research or by wire transfer in immediately available funds to Chevron Research's bank, each as designated in Article 8-0 hereof. ARTICLE 7-0 - RESPONSIBILITY AND LIABILITY 7.1 Neither party shall be liable for failures and delays in performance due to any cause or circumstance beyond its reasonable control, including, without thereby limiting the generality of the foregoing, any failures or delays in performance caused by differences with workmen, lockouts, fires, acts of God or the public enemy, riots, incendiaries, interference by civil or military authorities, compliance with the laws of the United States or with the orders of any governmental authority, compliance with public policy, delays in transit or delivery on the part of transportation companies or communication facilities, or any failure of sources of material. 7.2. Although Chevron Research represents that the work and services performed by it under this Agreement shall be -18- <PAGE> 20 performed in accordance with accepted engineering standards, South Hampton acknowledges that the AROMAX Process is not yet commercialized and that the Licensed Unit is a scale-up demonstration and test unit. Chevron Research's only liability, if any, respecting the Licensed Unit and/or the operation of it and/or the Demonstration Run, including but not limited to any breach of the foregoing representation or for any losses, damages, claims or demands of any nature arising out of work and services provided under this Agreement, to South Hampton and/or South Hampton's contractors and/or third parties shall be that set forth in Section 5.l(5)(b) above.

Except as provided in Article 5-0, South Hampton shall have complete control of the construction, erection, alteration, maintenance, repair and operation of Licensed Unit at all times. ARTICLE 8-0 - TERM AND TERMINATION 8.1. Chevron Research's obligations to South Hampton pursuant to Article 5-0 to perform services, make payments, or incur costs for its own account with respect to the Demonstration Run or the Licensed Unit shall terminate upon completion of the Demonstration Run. -19- <PAGE> 21 8.2. In the event of a breach of any provision of or default in any obligation under this Agreement, including a failure or refusal by South Hampton to make payments to Chevron Research as required by Article 6-0, unless the breaching party fully remedies such breach with reasonable promptness under the circumstances after the breach is called to its attention in writing by the other party, then such other party may terminate this Agreement by giving the breaching party written notice of termination. No such termination for breach shall relieve the breaching party of any liability for breach incurred prior to the effective date of said termination or from the obligation to fulfill any payment obligation based on operations prior to said effective date of termination. No express or implied waiver of any breach of any of the provisions of this Agreement shall constitute a waiver of any subsequent breach of the same or different provisions hereof. The right of termination provided in this section is in addition to any other rights available by law, including the right to sue for breach without terminating. 8.3. South Hampton may terminate this Agreement at any time after the expiration of seven (7) years from the date on which the Licensed Unit first goes on stream, by giving sixty (60) days' prior written notice to Chevron Research. The date on which the Licensed Unit first goes on stream shall be the startup -20- <PAGE> 22 date for the Demonstration Run unless otherwise agreed by Chevron Research and South Hampton. 8.4 If there is either a process failure of the AROMAX Process after startup of the Licensed Unit so that the Licensed Unit does not produce hydrogen (a need to regenerate AROMAX Catalyst is not a process failure) or a delay in startup beyond two weeks after commencement of plant cleanup, as provided in Section 5.l(5)(b), and if Chevron Research's total liability in the event of such a process failure or delay pursuant to Section 5.1(5)(b) is or will be exceeded, South Hampton may, at its election, terminate either the Demonstration Run (if started) or this Agreement by written notice to Chevron Research. 8.5. Upon any termination of this Agreement South Hampton shall retain its right to use Chevron Research's Technical Information in the Licensed Unit and its rights under Chevron Research's Patent Rights and Catalyst Patent Rights but only to the extent to which, had this Agreement not been terminated, South Hampton would have been entitled to process Stock Charge without payment to Chevron Research. Termination of this Agreement shall not terminate Chevron Research's right to use and to disclose South Hampton's Technical Information provided in Article 4-0 or Chevron Research's rights under South Hampton's Patent Rights and Catalyst Patent Rights as provided in Article 3-0. However, the rights retained by South Hampton and -21- <PAGE> 23 Chevron Research after termination shall not extend to any Patent Rights or Catalyst Patent Rights based on inventions made after the effective date of termination or to any information developed or acquired after the effective date of such termination. 8.6. In the event of termination, South Hampton shall not be entitled to refunds of any amounts paid hereunder and if South Hampton has authorized Chevron Research to perform work for South Hampton for which payment would be due to Chevron Research, South Hampton shall pay Chevron Research an amount for reasonable costs incurred as preparation for work authorized but not yet performed and incurred in shutting down services then being performed. 8.7. Termination of this Agreement shall not affect either party's right to enforce any obligation or liability accruing under this Agreement prior to the effective date of termination. Termination of this Agreement shall not relieve South Hampton or Chevron Research with respect to protection and use of confidential Technical Information as provided in Article 4-0. 8.8. Unless sooner terminated as hereinabove provided, this Agreement shall continue in full force and effect for a period of fifteen (15) years from the effective date, on which date this Agreement shall automatically terminate. -22- <PAGE> 24 ARTICLE 9-0 - GENERAL PROVISIONS 9.1 The addresses of the parties hereto are as follows: Chevron Research: Chevron Research Company Licensing and Catalyst Division P.O.
