                        ARTICLE 2: GRANTS AND CONDITIONS

2.1  AET hereby grants to Gateway, subject to terms, covenants, conditions and
     limitations set forth in this Agreement, the exclusive rights and licenses,
     including Know-How and Patent Rights, in the United States to design,
     construct, build, license, operate, sell, install, assign, lease, rent,
     repair, maintain, revise and revamp Mehra Gas Treating Units either
     individually or jointly with others including by sublicense and subcontract
     for individual Units ("Grant"). Furthermore, AET shall grant the rights and
     licenses set forth in this Agreement to any purchasing entity or assignee
     if such rights, licenses or grants are required to consummate the
     transaction or to operate or maintain the Unit.


                                       3
<PAGE>


2.2  The Grant to Gateway shall apply to Mehra Gas Treating Units used in, or in
     anyway involved with, the production of natural gas. AET hereby agrees that
     it shall not design, construct, build, operate, install, lease, sell, rent
     or assign a Mehra Gas Treating Unit for treating natural gas in the United
     States nor grant a right or license for a Mehra Gas Treating Unit to any
     other party for treating natural gas in the United States for as long as
     Gateway's exclusive Grant is in force and effect.

2.3  If as of December 31, 2004 or as of any December 31st thereafter Gateway
     (including any sublicensee, subcontractor, purchasing entity or assignee of
     Gateway pursuant to Paragraph 2.1, and including any grantee or assignee of
     AET approved by Gateway) has not installed, sold or leased a Unit or Units,
     which have initiated Start-up, with a combined Maximum Rated Feed Capacity
     at least equal to the Target Capacity as defined below, then AET shall have
     the right to cause this Agreement to be modified as set forth herein by
     giving written notice to Gateway within sixty (60) days after the end of
     the calendar year for which the Target Capacity has not been met. If such
     written notice is given on a timely basis, then effective at the end of a
     thirty-day period following receipt of said notice by Gateway, the first
     sentence of Paragraph 2.1 of this Agreement will be modified by deleting
     the word "exclusive". The Target Capacity for December 31, 2004 is 20,000
     Mcf per day. The Target Capacity will increase by 10,000 Mcf per day as of
     the end of each calendar year thereafter.

     The Maximum Rated Feed Capacity (15,300 Mcf per day) of the Unit installed
     at a facility near Madisonville, Texas pursuant to License Agreement to
     Practice Nitrogen Rejection Technology dated December 24, 2001 among AET,
     Gateway and Hanover Compression Limited Partnership ("Hanover") is to be
     included in the combined Maximum Rated Feed Capacity of Units as of
     December 31, 2004 and each December 31 thereafter in determining whether or
     not the Target Capacity has been achieved.

     Furthermore, if Hanover or a third party enters into a license agreement in
     2004 for one or more additional Units at the facility near Madisonville,
     Texas and part or all of the license fees payable to AET pursuant to said
     license agreement are paid prior to December 31, 2004, then the Maximum
     Rated Feed Capacity of said Unit or Units shall be included in the combined
     Maximum Rated Feed Capacity of Units as of December 31, 2004 and each
     December 31 thereafter in determining whether or not the Target Capacity
     has been achieved, notwithstanding the fact that the Unit or Units do not
     initiate Start-up in 2004.

2.4  In the event a non-exclusive Grant is in effect pursuant to Paragraph 2.3,
     the fees to be paid and the timing of such payments by Gateway to AET and
     all other terms and conditions with respect to Mehra Gas Treating Units
     shall be no less favorable to Gateway than to any other grantee, licensee
     or user of the Patent Rights and Know-How.

2.5  As between AET and Gateway, Gateway is solely responsible for developing
     and negotiating agreements with third parties to treat natural gas
     employing the Mehra Gas Treating Units. During Proposal Activities, Gateway
     may request reasonable Proposal Technical Support from AET to facilitate
     negotiations between Gateway and the third party, such third parties
     including Gateway Affiliates. AET will provide reasonable Proposal
     Technical Support requested by Gateway in a timely manner. AET and Gateway
     shall agree on the scope of the Proposal Technical Support that AET will


                                       4
<PAGE>


     provide, the fixed price that Gateway will pay AET for the Proposal
     Technical Support and the time when payment is to be made. It is also
     agreed that the fixed price for the Proposal Technical Support will
     reimburse AET for the incremental costs incurred for performing the work,
     including professional time and travel, and other direct expenses. AET
     assumes no responsibility or liability for Gateway's use or application of
     Proposal Technical Support Information.

2.6  When Gateway elects to construct a Mehra Gas Treating Unit, AET will
     provide Gateway with a certified Process Design Basis Package for the Unit
     under consideration within thirty (30) days after Gateway gives AET the
     information specified in Annex IV under the heading "Mehra Gas Treating
     Unit Duty Specifications". Gateway will pay AET $45,000.00 (Forty-Five
     Thousand Dollars) for the Process Design Basis Package for the first Mehra
     Gas Treating Unit it constructs and $30,000.00 (Thirty Thousand Dollars)
     for the Process Design Basis Package for each subsequent Mehra Gas Treating
     Unit it constructs. Fifty percent of the applicable payment will be made
     when the Process Design Basis Package is initiated for a Unit and the
     remaining fifty percent of the payment will be paid upon completion of the
     Process Design Basis Package.

     It is not contemplated that AET will perform functions of an engineering
     and construction contractor or take on any responsibility for directing the
     work of the engineering and construction contractor that Gateway selects to
     design and build a Mehra Gas Treating Unit. It is contemplated that the
     certified "Process Design Basis Package" shall be adequate and complete to
     permit a qualified engineering and construction contractor to develop the
     process and instrument drawings (P&ID), mechanical flow diagrams, and do
     the detailed engineering and construction of the Mehra Gas Treating Unit.

     The engineering and construction contractor selected by Gateway will
     prepare in consultation with AET the P&ID's, which are typically the first
     step in the detailed engineering of a process plant. Gateway and AET shall
     use their reasonable efforts to have the certified Process Design Basis
     Package incorporated in the P&ID's. For a new Mehra Gas Treating Unit which
     is a close derivative of a previous Mehra Gas Treating Unit, the Process
     Design Basis Package for the new Unit that AET prepares may be transferred
     in the form of revisions and modifications to a set of P&ID's for an
     existing Unit. AET shall use P&ID's and the other portions of the Detailed
     Design produced by the engineering and construction contractor solely for
     those purposes.

     Notwithstanding the requirements in Paragraphs 2.5 and 2.6 of this Article
     2, AET will provide Proposal Technical Support and the Process Design Basis
     Package to Gateway for two Mehra Gas Treating Units selected by Gateway at
     no initial charge to Gateway; provided, however, that if either of said
     Units is constructed, Gateway will pay AET the respective Proposal
     Technical Support and Process Design Basis Package fees for that Unit at
     Start-up of the Unit. Gateway will advise AET prior to commencement of the
     Proposal Technical Support for a Unit whether or not the Proposal Technical
     Support and the Process Design Basis Package for that Unit will be subject
     to this provision.

2.7  AET agrees to provide reasonable technical assistance, consultation, and
     oversight to Gateway and/or to Gateway's engineering and construction
     contractor for the sole purpose of properly incorporating the Process
     Design Basis Package into the Detailed Design of the Mehra Gas Treating


                                       5
<PAGE>


     Unit. AET will not charge Gateway for this technical assistance; however,
     Gateway will reimburse AET the cost of reasonable travel and living
     expenses when the work is done away from AET's office.

2.8  During the preparation of the Detailed Design of the Mehra Gas Treating
     Unit, AET will timely review the Detailed Design specifications as they are
     released by the engineering and construction contractor retained by Gateway
     and promptly point out to Gateway in writing all material deviations from
     proper implementation of the Process Design Basis Package in the Detailed
     Design; and Gateway will advise the contractor to bring the Detailed Design
     into conformance with the certified Process Design Basis Package.

     It is contemplated that the Mehra Process Sections will be standardized as
     much as possible for all applications. However, the performance of the
     Mehra Process Sections will vary with feed composition and conditions and
     product specifications. It is also contemplated that the compression and
     refrigeration sections will be designed and built by equipment vendors to
     duty specifications provided by AET as part of the certified Process Design
     Basis Package.

2.9  Before Gateway approves the final Detailed Design specifications of a Mehra
     Gas Treating Unit for construction, AET shall state in writing that the
     certified Process Design Basis Package has been properly incorporated into
     the Detailed Design for the Unit.

2.10 AET must preapprove any contractor or consultant retained by Gateway to
     work with AET's technical information. AET will not unreasonably withhold
     approval.

2.11 AET, at Gateway's request, will provide one employee skilled in the Mehra
     Process technology at the plant site during the installation and Start-up
     period for consultation up to a maximum of sixty (60) days at no charge to
     Gateway, except Gateway will pay the cost of reasonable travel and living
     expenses for AET's employee.

2.12 If it is mutually agreed by AET and Gateway that a consultant who is not an
     employee of AET is required to perform any of the services of AET required
     or permitted under this Agreement, the cost for the consultant shall be
     paid by AET, except that the cost of reasonable transportation and living
     expenses of the consultant shall be paid by Gateway.

2.13 While an exclusive Grant is in existence pursuant to this Agreement,
     Gateway agrees that if nitrogen must be removed from natural gas in the
     United States to make the natural gas marketable Gateway will have an
     ownership interest only in a Mehra Gas Treating Unit for said purpose.


                           ARTICLE 3: CONFIDENTIALITY

3.1  Gateway agrees to receive and maintain the Know-How, and all documentation

                        ARTICLE 4: PERFORMANCE GUARANTEES

4.1  AET warrants each Mehra Gas Treating Unit will start-up and meet the
     performance parameters specified for each Unit in the certified Process
     Design Basis Package for the Unit ("Performance Guarantees"), subject to
     the following conditions:

     (a)  AET has certified that the Detailed Design is in conformance with the
          certified Process Design Basis Package;

                                       7

<PAGE>


     (b)  The Mehra Gas Treating Unit meets generally accepted standards, codes
          and practices for design and construction of process plants in the
          locale where the Unit is installed in the U.S.; and

     (c)  The inlet natural gas composition and inlet conditions are those
          specified in the certified Process Design Basis Package for the Unit.

4.2  AET makes no warranty, express or implied, for the Mehra Gas Treating Unit
     with respect to its mechanical, civil and electrical design, its materials
     of construction (other than as may be specified in the certified Process
     Design Basis Package), purchased materials and equipment, its construction,
     its compliance with OSHA, SARA, materials handling, and other State or
     Federal safety and operating regulations and standards, its compliance with
     environmental pollution control regulations (except that if subparagraph
     4.1 (a), (b) and (c) are met, the projected effluents of the Unit will meet
     such regulations if properly stored and vented), and its operability and
     mechanical maintainability. AET accepts no responsibility or duty to
     participate, and will not participate in the operation, management and
     control of the Mehra Gas Treating Unit. AET accepts no liability to Gateway
     or to indemnify Gateway for claims by third parties whom AET may interact
     with in the course of the construction, operation and maintenance of the
     Mehra Gas Treating Unit (unless the claim arises as a result of a direct
     intervention or instruction by AET carried out in the operation of the
     Unit), implementing its safety procedures, in compliance with OSHA and
     other State and Federal safety and operating regulations and standards, and
     State or Federal pollution control regulations for safety, environmental
     pollution controls of the Unit and equipment.

4.3  Within thirty days after the Start-up is complete and the Unit's operating
     conditions are at a steady state and free of mechanical and equipment
     problems which would interfere with obtaining reliable process operating
     data, at a time mutually agreed to by Gateway and AET, Gateway shall
     conduct a Performance Guarantee test to obtain the performance parameters
     ("Performance Guarantee parameters") set out in the certified Process
     Design Basis Package using the feed natural gas specified in the final
     certified Process Design Basis Package. AET shall provide an observer
     present at the plant site during the Performance Guarantee tests at no
     charge to Gateway, except the cost of reasonable transportation and living
     expenses which shall be paid by Gateway.

     Accepted statistical methods will be used to determine if the Performance
     Guarantee parameters are achieved based on data during a period of
     reasonably lined out steady state continuous operation lasting at least 48
     hours.

     If the Mehra Gas Treating Unit cannot meet one or more Performance
     Guarantee parameters, data will be obtained which, in the aggregate,
     establish the actual performance for those parameters at best attainable
     operation, and the procedures of Paragraphs 4.4 and 4.5 shall be followed.

4.4  If, at the time of Performance Guarantee testing, the inlet natural gas
     composition and/or feed rate is materially different from the conditions
     assumed in the certified Process Design Basis Package, then AET in
     consultation with Gateway will recompute Performance Guarantees using the
     materially different conditions experienced and the computation methods
     used to compute the original Performance Guarantees specified in the


                                       8

<PAGE>


     certified Process Design Basis Package, and these recomputed values will
     replace the values specified in the certified Process Design Basis Package
     for the Unit.

4.5  If one or more Performance Guarantee parameters is not statistically
     attained for the Unit and the deviation is due in whole or in part to a
     deficiency in the certified Process Design Basis Package and not a
     deficiency in mechanical design, equipment performance or operation, then
     AET shall have the opportunity to propose reasonable modifications to
     operating procedures and/or process design which can be implemented at
     reasonable costs and reasonable time to bring the deficient performance
     parameter up to guaranteed level. The cost and interest thereon of these
     modifications will be deducted from the fees to be paid by Gateway to AET
     under this Agreement and such deductions shall be credited as fees paid to
     AET. If reasonable modifications to cure Performance Guarantee parameter
     deficiencies are not practical or feasible and the Unit will operate
     permanently at below Performance Guarantee parameters, then Gateway shall
     inform AET of the lost profits and interest thereon ("Lost Profits")
     Gateway or its sublicense will incur which shall be equal to the reduction
     in lease or purchase payments and raised operating costs charged to Gateway
     or its sublicense that are realized for the Unit, and such Lost Profits
     will be deducted from the fees to be paid by Gateway to AET under this
     Agreement.


                                 ARTICLE 5: FEES

5.1  In consideration of the rights granted by AET to Gateway in this Agreement,
     upon completion of the Performance Guarantee test (for each Unit), and
     subject to all deductions and offsets by Gateway, including all set out in
     this Agreement for all Units, including costs incurred for changes made to
     a Unit as a result of changes made to the certified Process Design Basis
     Package, all of which shall be considered fees paid under this Agreement,
     Gateway shall pay AET the following fees for each Unit:

     (a)  For the Patent Rights a rate of two cents ($.02) per thousand (1,000)
          Standard Cubic Feet fed to the Mehra Gas Treating Unit for so long as
          there is at least one unexpired, extant U.S. Patent believed valid and
          owned by AET which has at least one claim reading on the Mehra Gas
          Treating Unit. The payments are due monthly for each calendar month on
          the last day of the subsequent calendar month. For calendar months
          beginning after the 90th day after Start-up is completed in which the
          natural gas fed to any Mehra Process section is greater than zero but
          less than 30,000 (thirty thousand) Standard Cubic Feet per calendar
          month, the monthly payment shall be computed as if the natural gas fed
          to that Mehra Process section in that calendar month were 30,000
          (thirty thousand) Standard Cubic Feet of natural gas.

     (b)  For Know-How a rate of three ($.03) per thousand (1,000) Standard
          Cubic Feet of natural gas fed to Mehra Gas Treating Units for as long
          as the Unit operates. The payments are due monthly for each calendar
          month on the last day of the subsequent calendar month. For calendar
          months beginning after the 90th day after Start-up is completed in
          which the natural gas fed to any Mehra Process section is greater than
          zero but less than 30,000 (thirty thousand) Standard Cubic Feet per
          calendar month, the monthly payment shall be computed as if the
          natural gas fed to that Mehra Process section in that calendar month
          were 30,000 (thirty thousand) Standard Cubic Feet of natural gas.


                                       9
<PAGE>


     (c)  For Grade A Helium (99.995 mol% purity or higher) recovered and sold
          from Mehra Gas Treating Units, for Patent Rights and Know-How, a
          monthly payment of $1.00 (One Dollar) per thousand Standard Cubic Feet
          of Grade A Helium recovered and sold for so long as there is at least
          one unexpired, extant U.S. Patent believed valid and owned by AET
          which has at least one claim reading on the Mehra Gas Treating Unit.
          For non-Grade A Helium recovered and sold from the Mehra Gas Treating
          Units, the payment will be $0.50 (Fifty Cents) per thousand Standard
          Cubic Feet of non-Grade A Helium recovered and sold. The payments are
          due monthly for each calendar month on the last day of the subsequent
          calendar month.

     (d)  The payments Gateway makes to AET for Proposal Technical Support and
          the Process Design Basis Package for a Mehra Gas Treating Unit under
          Paragraphs 2.5 and 2.6 and all other deductions and offsets set out in
          this Agreement for all Units shall be offset against the monthly
          payments due under Paragraph 5.1.

     (e)  The fees specified in Paragraphs 5.1 (a), 5.1 (b) and 5.1 (c) shall
          prevail for Mehra Gas Treating Units for which AET provides the
          Process Design Basis Package in calendar years 1997 and 1998. For
          Mehra Gas Treating Units for which AET provides the Process Design
          Basis Package in calendar year 1999 and each calendar year thereafter,
          the fees in Section 5.1 (a), 5.1 (b) and 5.1 (c) will be adjusted by
          multiplying these base fees by a fraction of indices published by the
          U. S. Department of Commerce ("Producer Price Index"), the numerator
          of which is the Producer Price Index for the second previous year and
          the denominator of which is the Producer Price Index for calendar year
          1996. For example, the fees for a Unit for which the Process Design
          Basis Package is provided in year 2000 will be determined by using as
          a numerator the Producer Price Index for year 1998. The Producer Price
          Index is before seasonal adjustment and the final Producer Price Index
          for the month of December will be used as the index for a calendar
          year.


                      ARTICLE 6: PATENT RIGHTS AND KNOW-HOW

6.1  AET will maintain and pay maintenance fees for the U.S. Patents listed in
     Annex II. All of the U.S. Patents are currently extant.

6.2  AET represents and warrants that it is the owner of the Patent Rights and
     Know-How, including as incorporated in the Mehra Gas Treating Units, and
     does not require rights from the U.S. patents or know-how of any other
     Person that are not obtainable through the purchase of equipment or
     services for use with the Unit. AET knows of no Person presently infringing
     any of the Patent Rights or who has misappropriated any Know-How, nor does
     AET have any reason or notice that the Mehra Process misappropriates the
     know-how or infringes extant patent(s) of any other Person. AET knows of no
     reason why any of the Patent Rights are invalid or any of the Know-How
     would belong to another Person or any of the Know-How is not confidential.
     AET is not aware of anything or action which precludes it from entering
     into this Agreement. If another party asserts that its patent rights have
     been infringed or trade secrets misappropriated by the design, construction
     or operation of a Mehra Gas Treating Unit and the third party obtains an


                                       10

<PAGE>


     injunction from a court of competent jurisdiction ordering the Unit to
     cease operation in its current form, then all payments due AET from Gateway
     are suspended during the term of the injunction. AET also hereby agrees to
     indemnify and hold Gateway harmless from any money damages or awards
     finally assessed by a court of competent jurisdiction, for patent rights
     infringed or trade secrets misappropriated by the Mehra Gas Treating Units,
     subject to the following provisions:

     (a)  Gateway must promptly notify AET in writing of any notice Gateway
          receives claiming or asserting that a Mehra Gas Treating Unit
          infringes a patent or misappropriates a trade secret, and lend all
          reasonable assistance, at AET's expense, in the defense or settlement
          of such suit.

     (b)  If modifications to a Mehra Gas Treating Unit are required to avoid
          infringement or use of misappropriated technology, AET shall use its
          best efforts to determine such modifications and propose them to
          Gateway, and if such modifications are approved by AET and Gateway,
          then AET will pay for half the modifications and Gateway will pay for
          half the modifications. Gateway will be entitled to recover any
          payments it makes from future payments due AET under this Agreement.

6.3  AET shall bear the expense and shall have sole and complete control of the
     defense and settlement of all aspects of any suit with respect to which AET
     may have an obligation to indemnify Gateway under Paragraph 6.2. Gateway
     may, if it desires, employ counsel of its own choice and at its own
     expense, to monitor the progress of such suit with complete cooperation
     from AET's counsel and, if Gateway desires, to assist (in a manner not
     inconsistent with the direction of AET's counsel, which shall be lead
     counsel) in the defense, but shall not have the power or authority, express
     or implied, to settle, adjust or compromise any aspect of the suit in such
     a fashion as to impose any obligation upon AET for indemnification or
     otherwise.

6.4  If Gateway shall have given AET notice, as provided in Paragraph 6.2, of a
     claim by a third party which would be subject to indemnification under
     Paragraph 6.2, Gateway shall, at AET's written request detailing the
     required remedy or mitigation in the operation of the Unit without
     structural modification and which is safe, modify its practices in such a
     manner as in AET's judgment, as set out in the written request may avoid or
     materially limit the claim for infringement or misappropriation. If Gateway
     is required to shut down the Unit to comply with this provision or a
     judgment rendered by a court because the Unit infringes the patent rights
     of a third party or misappropriates technology of a third party, then at
     Gateway's request AET will purchase the Unit from Gateway for the cost of
     the Unit excluding its installation expense. If such modifications under
     Paragraph 6.2 (b) or 6.4 increase the expense or lower the output of
     Gateway's operations, Gateway may offset the value of Lost Profits to
     Gateway from fees payable to AET. If Gateway shall fail to reasonably
     comply with AET's said written request, AET shall thereupon be discharged
     from any further obligations or liabilities to Gateway accruing thereafter
     under Paragraph 6.2.


                       ARTICLE 7: IMPROVEMENTS AND ACCESS

7.1  AET will timely inform Gateway in writing of modifications to Mehra Gas
     Treating Units which, in the judgment of AET, can significantly improve
     performance of Mehra Gas Treating Units ("Improvements") and the Grant
     shall thereafter include all such Improvements therein.


                                       11
<PAGE>


7.2  Improvements to Mehra Gas Treating Units developed by Gateway during the
     term of this Agreement shall be the property of AET. Improvements shall
     include inventions which are statutory subject matter that can be patented
     under U.S. patent laws, 35 U.S.C., and also knowledge that can be
     classified as trade secrets. AET has the primary responsibility and will
     bear the cost for identifying, assimilating, transferring, patenting and
     protecting the Improvements. AET will notify Gateway of those Improvements
     to Mehra Gas Treating Units and file the patent applications. Gateway will
     cooperate with AET in this endeavor. From time to time, but not more often
     than six (6) month intervals, Gateway shall allow AET reasonable access to
     Gateway's operating Mehra Gas Treating Units, at times to be mutually
     agreed upon, during which AET may observe operation of the Units. AET may
     require Gateway to perform reasonable plant tests, and record operating
     data, but without interfering with or upsetting operation of the Mehra Gas
     Treating Unit. Gateway will contract with its employees to assign
     patentable improvement inventions to the Mehra Process technology to AET
     and use reasonable efforts to cause such inventors to assign such patents
     to AET. The cost of patenting Improvement inventions, including reasonable
     reimbursement for the value of the time Gateway's employees expend on
     preparing patents, will be borne by AET.

7.3  From time to time, at times to be mutually agreed upon, Gateway shall allow
     AET, accompanied by representatives of prospective licensees of Mehra
     Process technology, access to Gateway's Mehra Gas Treating Units, so that
     AET can show the Unit to prospective licensees to promote licensing of
     Mehra Process technology. These visits shall not interfere with operation
     of the Mehra Gas Treating Units.


                             ARTICLE 8: TERMINATION

8.1  AET may terminate this Agreement thirty (30) days after the effective date
     of a written notice to Gateway in the event Gateway:

     (a)  fails to make, within the thirty (30) day period set by the notice,
          any payment which is due and payable pursuant to this Agreement and
          has been in arrears for more than one (1) month; or

     (b)  commits a material breach of Article 3: Confidentiality of this
          Agreement which is not cured (if capable of being cured) within the
          thirty (30) day period set by the notice; or

     (c)  becomes insolvent or a petition in bankruptcy is filed against Gateway
          and is consented to, acquiesced in, or remains undismissed for ninety
          (90) days; or makes a general assignment for the benefit of creditors,
          or a receiver is appointed for Gateway, and Gateway does not return to
          solvency before the expiration of said thirty day period set by the
          notice;

     provided that if there is a dispute of such arrears or breach, termination
     shall not be effective until a determination of such arrears or breach has
     been made in accordance with Paragraph 9.8 and Gateway is given thirty (30)
     days thereafter to cure such arrears or breach.

8.2  Gateway may terminate this Agreement at any time following thirty (30) days
     written notice to AET.

     after the effective date of termination, Gateway will provide AET with a
     list of all such ventures to be covered by the Grant.

8.4  Termination of this Agreement shall not affect Gateway's right to continue
     the operation of all Units that have been built and its obligations to pay
     the fees set forth in Article 5, or the Confidentiality obligations set
     forth in Article 3, or the Performance Guarantees of Article 4 or the
     Patent Rights and Know-How indemnities and protection of Article 6, or for
     purposes of Paragraph 8.3, the Proposal Technical Support and the certified
     Process Design Basis Package and the Detailed Design, installation and
     start-up support of Article 2, and all sublicenses granted by Gateway to
     third parties as of the date of termination and all sublicenses granted
     pursuant to Paragraph 8.3.

8.5  Waiver by either party of a single default or breach or of a succession of
     defaults or breaches shall not deprive such party of any right to terminate
     this Agreement pursuant to the terms hereof upon the occasion of any
     subsequent default or breach.


                          ARTICLE 9: GENERAL PROVISIONS

                      ARTICLE 10: AET PROJECT PARTICIPATION

10.1 If Gateway participates in one or more Plant Projects, as said term is
     defined in Paragraph 10.2, in the United States, then AET shall have the
     option to participate in each such Plant Project. AET may elect to have an
     ownership interest in the Plant Project between a minimum of 10% and a
     maximum of 25% if Gateway initially owns 100% of the ownership interest in
     the Plant Project, or a proportionately reduced minimum and maximum range
     of ownership interest in such Plant Project if Gateway initially owns less
     than 100% of such ownership interest. For example, if Gateway has an
     initial 60% ownership interest in a Plant Project, then AET may elect to
     take a minimum of 6% up to a maximum of 15% ownership interest in the Plant
     Project.

10.2 The term Plant Project for the purpose of this Article 10 means the

     such information to return the executed AFE to Gateway indicating its
     election to participate in such Plant Project and the extent of its
     ownership percentage consistent with Paragraph 10.1. Failure of AET to
     return the executed AFE to Gateway in a timely manner will be deemed an
     election by AET not to participate in the Plant Project. If AET elects to
     participate in a Plant Project, then AET shall pay its ownership interest
     percentage of: (a) all capital costs set forth in the AFE pertaining to the
     Plant Project and (b) all operating and maintenance costs associated with
     the Plant Project.

                             MEHRA GAS TREATING UNIT



     A Mehra Gas Treating Unit is a process unit that uses non-cryogenic,
absorption-based Mehra Processsm technology to: 1) reject nitrogen from natural
gas; 2) flexibly recover ethane, propane, butane and heavier hydrocarbons from
natural gas; and 3) recover concentrated helium from natural gas. Figure 1 is a
simplified flow plan of the Hugoton Demonstration Unit which is a typical
embodiment of a Mehra Gas Treating Unit for nitrogen rejection.

     Referring to Figure 1, the natural gas feed entering the unit is dried by
contacting it with ethylene glycol which absorbs water vapor. The natural
gas/glycol mixture is cooled in coolers. During cooling hydrocarbon liquids
condense out of the natural gas. The natural gas stream is passed through a
separator where a wet glycol stream and a condensed hydrocarbon stream are
separated from the natural gas stream. The wet glycol stream is conveyed through
a glycol reboiler where water is boiled out of the glycol and the dry glycol is
recycled back into the incoming natural gas feed stream. The recovered
hydrocarbon liquids can be sold for fuel or chemical feed or fed into the
natural gas product stream, as market conditions dictate.

     The uncondensed gases from the separator are fed into the absorber where
they are contacted with lean solvent. The solvent absorbs methane and higher
hydrocarbons from the feed and leaves the absorber as the rich solvent absorber
bottoms stream. Nitrogen, and helium if present, leaves the tower in the
absorber overhead gas stream.

     The rich solvent absorber bottoms stream is flashed to reduced pressure in
the first flash drum. The flash gas from the first flash drum is compressed and
fed into the bottom of the absorber as the absorber stripping gas. The bottoms
stream from the first flash drum is conveyed to reduced pressure through one or
more additional flash drums in series. The flash-regenerated solvent stream from
the last flash drum is pumped through a cooler and then fed into the absorber as
the lean solvent stream. No heat is added to the flashing solvent.

     The overhead gas streams from the additional flash drums are compressed and
combined to form the natural gas product stream.

     The Unit includes a refrigeration system to provide refrigerant for coolers
in the Unit.

     The feed is cooled by heat exchange against cold product streams leaving
the unit to reduce refrigeration power consumption.

     Any helium in the natural gas feed leaves the process in the absorber
overhead gas stream along with nitrogen. Helium can be concentrated and
recovered by feeding the absorber gas stream into a Helium Recovery Unit before
releasing the stream to the atmosphere.

     There are several options that can be added to the Mehra Gas Treating Unit.
An expander can be installed in the absorber overhead line to recover shaft work
from letting the pressure of the absorber overhead stream down to exit pressure.
Turbines can be installed upstream of the flash drums to recover shaft work from
the flashing solvent streams.

     It is contemplated that Mehra Gas Treating Units will be constructed in
sections with each section built on a skid module which can be transported over
land by rail or truck. It is contemplated that the Mehra Process Sections will


                                       16

<PAGE>


be standardized with only minor modifications, not including changes in the
P&ID's, required to adapt the Unit to a specific application. The gas and
refrigeration compressors will be mounted on their respective skids. The
remaining equipment comprised of flash drums, separators and exchangers will
also be skid mounted. It is likely that the absorber column will be installed
off-skid. If a helium recovery section is specified it will be mounted
separately on additional skids. These sections will be built in factories and
transported to the Unit site where the sections will be placed on foundations,
connected and supplied with utilities. The Mehra Process module will be built in
a vendor factory to meet the certified Process Design Basis Package. The
refrigeration and compressor modules will be fabricated by suitable equipment
vendors to meet duty specifications which meet the requirements of the certified
Process Design Basis Package.

     A Mehra Gas Treating Unit may consist of one or more standardized Mehra
Process Sections operating in parallel. However, it is contemplated that only
one refrigeration and one compressor module sized to service all the Mehra
Process Sections in the Unit will be provided. Additional feed gas compression
and acid gas removal facilities may be provided as necessary for a specific
application of the Mehra Gas Treating Unit. Liquid product stabilization system
may additionally be provided.
