               GE purchasing all of its requirements for heavy duty gas turbines
               for catalytic combustion systems (as used in this Agreement, the
               term "catalytic combustion system" means a gas turbine combustion
               system that employs a catalyst upstream of the turbine inlet and
               integrated with the combustion process and shall not include SCR,
               SNCR, SCONOx or other catalytic devices employed in pollution
               clean-up) from CCSI during the term of any license rights granted
               under this Section 6.2.1 (otherwise, GE's license rights shall be
               non-exclusive).

     6.2.2     Upon the expiration of the Incentive Term relating to Gas
               Turbines, the exclusive license granted in Section 6.2.1 shall be
               limited to GE-designed Gas Turbines so that CCSI can thereafter,
               itself or through its licensees, sell and offer to sell the
               Products to Third Parties for non GE-designed Gas Turbine
               applications under the CCSI Technology.

               Furthermore, and in the alternative, GE may, in its sole
               discretion (after giving due regard to CCSI's concerns), elect to
               terminate the Incentive Term prior to its expiration date by
               written notice to CCSI setting forth such expiration date, and in
               such event, the length of the Additional Period shall be
               increased on an equivalent basis to compensate GE for any such
               reduction in the Incentive Term (such that the Additional Period
               shall commence on the date of termination of the Incentive Term
               and expire on the same date it would have expired if the
               Incentive Term (including any modifications pursuant to Sections
               7.3, 7.4 and 7.5) had not been terminated early). In addition, in
               a timely fashion after the Effective Date, or from time to time
               thereafter as appropriate, CCSI and GE shall consider in good
               faith other modifications of the Incentive Term, including
               elimination of all or any part of the Incentive Term in exchange
               for appropriate compensating expansions of the Additional Term

       (b) set forth in paragraph 6.2.2 (that is by giving GE the right during
       the Additional Period to purchase Product [*], which shall hereinafter be
       referred to as [*]), then CCSI shall use its best efforts to keep books
       and records accurately showing all CCSI pricing of Products to [*] during
       the term of this Agreement. Such books and records shall be subject to
       inspection by an independent auditor acceptable to CCSI at reasonable
       times, but not more frequently than once every twelve months, for the
       purpose of verifying the accuracy of [*] under the aforesaid Section
       6.2.2. The fees and expenses of the auditor performing such an
       examination shall be borne by GE. These books and records shall be
       preserved for at least two (2) years from the date [*] to which they
       pertain. Further, if the independent audit reveals to GE that CCSI has
       not given GE [*] for any Products, as required in Section 6.2.2 then CCSI
       shall promptly (within thirty (30) days) after receipt of written notice
       from GE of the Shortfall ("Shortfall" being defined as the sum of the
       difference between the prices actually paid by GE and [*] in question)
       either a) refund to GE the Shortfall plus [*] of such Shortfall as a
       penalty (at GE's option, either as a credit against future Product sales
       or as a cash payment) or, b) if CCSI in good faith disagrees with the
       independent auditor's report, immediately request binding arbitration
       solely on the issue of the correctness of the Shortfall

       amount as reported by GE's independent auditor. Within thirty (30) days
       after any written request by CCSI for arbitration on the Shortfall issue,
       CCSI and GE shall agree on an independent expert arbitrator to review all
       of the relevant evidence including the GE auditor's report and render a
       decision on the correctness of the Shortfall reported by the independent
       auditor. The site of arbitration shall be New York, NY, unless otherwise
       agreed. Both parties shall use all reasonable efforts to select the
       independent arbitrator and complete the arbitration within sixty (60)
       days after GE's written notice of the Shortfall as set forth above. The
       decision of the independent expert arbitrator shall be final and binding,
       and the party found to be in error shall pay all of the costs of the
       independent arbitrator in reaching his/her decision. In the event CCSI is
       found to be in error and CCSI does not immediately compensate GE for the
       Shortfall as set forth above, or if CCSI does not immediately pay GE in
       cases where CCSI does not dispute the Shortfall amount, GE shall have the
       immediate right to terminate for cause as set forth in Sections 13.1 and
       13.4 below for CCSI failure to pay any Shortfall amounts.

                                   ---------

                               COMMERCIALIZATION
                               -----------------

The  Commercialization of the Products shall be subject to the Commercialization
Plan attached hereto as Exhibit B and the provisions of this Article 7.

7.1.   Supply Agreement.  During the Incentive Term and during the Additional
       ----------------
       Period provided in this Article 7, CCSI shall supply all of GE's
       requirements for the Products for incorporation into Gas Turbines,
       provided that CCSI can meet GE's quality, quantity and schedule
       requirements, pursuant to the Purchase Terms and Conditions set forth in
       Exhibit C. During this period, GE reserves the right to engage in Pre-
       commercial Activities with Third Parties regarding catalytic combustion
       systems for use on any GE gas turbine, provided CCSI shall have the right
       to treat any purchase or accepted written offer to purchase by GE of
       catalytic combustion systems for heavy duty gas turbines from a Third
       Party or other obtaining by GE, through license or otherwise, of
       catalytic combustion systems for such heavy duty gas turbines during the
       Incentive Term, as a material breach of this Agreement, triggering CCSI's
       rights under Sections 8.1, 13.1.3 and 13.3 hereof.

7.2.   Purchase Terms.  All GE purchases from CCSI of the Products shall be
       --------------
       subject to the Purchase Terms and Conditions as set forth on Exhibit C.

           CONFIDENTIAL TREATMENT HAS BEEN REQUESTED WITH RESPECT TO
                             THE OMITTED PORTIONS.

       7.2.1   During the Incentive Term, such purchases will be subject to
               "value pricing", meaning that the Products shall be priced so
               that CCSI receives an equitable share of the value, based on
               market advantages offered by the Products, which GE is able to
               obtain in pricing Gas Turbines incorporating the Products, in a
               pricing strategy which takes into account the price of competing
               technologies such as DLN and SCR. If the parties cannot agree on
               a price for GE's purchase of the Products using the above value
               pricing approach, CCSI shall have the option of setting a sales
               price which incorporates a value price which GE may accept or
               reject. In all cases, GE shall retain the right to establish, in
               its sole discretion, the prices of its products, including
               products incorporating the Products.

       7.2.2   In any event and as further consideration for GE's contribution
               to the Commercialization Program, to the extent GE procures all
               of its requirements for Gas Turbine catalytic combustion systems
               from CCSI, [*]

       7.2.3   To assist CCSI in planning its manufacturing activities, GE shall
               promptly provide CCSI with its best estimate of its requirements
               for goods over the next annualized or consecutive twelve (12)
               month period broken down by one (1) month periods. Further GE
               shall update this twelve (12) month estimate on a calendar
               quarter basis, such that CCSI receives a revised estimate of GE's
               requirements for the goods for the next four (4) calendar
               quarters. If GE places any firm orders which exceeds by more than
               fifty percent (50%) the rolling twelve (12) month estimates, CCSI
               shall use all reasonable efforts to fill such order but shall not
               be in breach for failure to do so unless GE gives CCSI at least
               six months written notice of the revised estimate.

       7.2.4   For the purposes of Article 7 of Exhibit C, Terms & Conditions of
               Purchase, GE and CCSI shall agree upon CCSI's process and control
               system and such agreed upon system shall be deemed acceptable to
               GE for purposes of Article 7 of Exhibit C, Terms & Conditions of
               Purchase.

7.3.   Extension of the Incentive Term - Year 2003 Deliveries. If, on or before
       ------------------------------------------------------
       January 1, 2002, GE commits in writing to purchase XONON Modules for
       delivery in calendar year 2003 in the following quantities, the Incentive
       Term for Gas Turbines only shall be extended as follows:

          shipped for which the customers do not require SCR or equivalent NOx
          control systems), or six (6) such Gas Turbines (whichever is greater),
          then the Incentive Term shall be extended by one (1) year, over and
          above any extension provided for in Section 7.3 above.

     7.5. Reduction of Incentive Term. If GE fails, through no fault of CCSI, to
          ---------------------------
          meet the target dates for first Gas Turbine firings as set forth in
          the Commercialization Plan attached hereto as Exhibit B, then the
          Incentive Term for each Market Segment (excluding the Syntroleum
          Market Segment, if funding from Syntroleum or other Third Party
          funding to fully fund the Syntroleum Program cannot be obtained in
          timely fashion) shall be reduced as follows:

                 resolution of its Board of Directors or stockholders for the
                 purpose of effecting any of the foregoing; or

         13.1.2  A proceeding or case shall be commenced without the application
                 or consent of the other party and such proceeding or case shall
                 continue undismissed, or an order, judgment or decree approving

                 unstayed in effect, for a period of ninety (90) days from and
                 after the date service of process is effected upon the other
                 party, seeking (a) its liquidation, reorganization, dissolution

                 substantially all of its debts, (b) the appointment of a

         13.1.3  Except as otherwise provided in Article 15 below, upon or after
                 the breach of any material provision of this Agreement, if the
                 breaching party has not cured such breach within ninety (90)
                 days after notice thereof from the other party, this Agreement
                 shall terminate for cause, at the option of the other party,
                 upon the expiration of such ninety (90) day cure period.
                 Notwithstanding the foregoing, GE shall have the right to
                 terminate this Agreement for cause upon thirty (30) days notice
                 if GE has terminated any three (3) purchase orders due to CCSI

                 twelve (12) month period.

                 In addition, GE may terminate this Agreement for cause in
                 accordance with Article 16 due to an assignment of this
                 Agreement, or a transfer of control of CCSI, to a Competing
                 Manufacturer.

         13.1.4  In the event that either GE or CCSI elects to terminate this
                 Agreement under the provisions of this Section 13.1 or Section
                 13.2, the other party shall have the right, within thirty (30)
                 days of receipt of a termination notice, to request binding
                 arbitration on the issue. In such event, CCSI and GE shall
                 agree on an independent arbitrator to review the relevant
                 evidence and render a decision on whether termination is
                 justified under the circumstances. The site of arbitration
                 shall be New York, NY if requested by CCSI and in San
                 Francisco, CA if requested by GE, unless otherwise agreed. Both
                 parties shall use all reasonable efforts to select the
                 independent arbitrator and complete the arbitration within
                 sixty (60) days after the notice of request for arbitration.
                 The decision of the arbitrator shall be final and binding, and
                 the non-prevailing party shall pay all of the costs of the
                 arbitrator. If arbitration is requested hereunder,

                 in no event shall any remedies provided in this Agreement and
                 triggered by default under this Section 13.1 be implemented
                 until after the decision of the arbitrator has been rendered.

13.2.    Termination Without Cause. Either party shall have the unilateral right
         -------------------------
         to terminate this Agreement by giving written notice to the other party
         (a) at any time, if the parties are unable, after best efforts, to
         raise funds from Third Parties within a Market Segment in at least an
         amount equal to the difference between (i) the Target Funding Amount
         for such Market Segment, and (ii) the Maximum GE Required Contribution
         for such Market Segment, excluding the Syntroleum Market Segment, or
         (b) after the end of the Initial Term, upon the terminating party's
         written notice to the other party of significant technical issues which
         indicate that the technical objectives of the Commercialization Program
         are not achievable or cannot be achieved within the timetable
         established in the Development Workplan or any extension thereof agreed
         to by the parties; with GE having the right to terminate under (b)
         above only if the technical issues relate to the XONON Module or XONON
         Components, and CCSI having the right to terminate under (b) above only
         if the technical issues relate to the GE Components.

13.3.    Consequences of Termination -- CCSI Not in Default. In the event this
         --------------------------------------------------
         Agreement is terminated by GE under Section 13.2, or by CCSI under
         Section 13.1: (a) CCSI shall have no obligation to make improvements to
         the XONON Combustion System available to GE beyond those developed in
         the Commercialization Program prior to such termination; (b) GE's
         licenses under CCSI Technology pursuant to Section 6.2.1 shall become
         non-exclusive, (c) GE's right to [*] under Article 6 shall be
         extinguished, (d) GE's rights to [*], rights to purchase and sole
         distribution rights under Article 7 shall all terminate, and (e) if GE
         elects to pursue its options under Section 8.1, GE shall pay CCSI the
         predetermined royalty or fee as provided therein.

13.4.    Consequences of Termination -- GE Not in Default. In the event this
         ------------------------------------------------
         Agreement is terminated by CCSI under Section 13.2, or by GE under
         Section 13.1: (a) GE's licenses under CCSI Technology pursuant to
         Article 6 shall continue in effect and CCSI shall promptly arrange with
         GE for a Third Party source of supply (as a vendor to CCSI) of the
         XONON Combustion System using the procedure set forth in Section 7.7
         above which assures GE of a continuing and uninterrupted source of
         supply for the XONON Modules and/or XONON Components, and (b) GE's
         rights to [*] under Articles 6 and 7 as well as GE's rights to [*],
         rights to purchase and sole distribution rights under Article 7 shall
         all survive such termination.

         Further, if GE terminates under Section 6.3 above because of failure on
         the part of CCSI to pay any Shortfall under Section 6.3 which CCSI is
         obligated to pay under said Section 6.3, CCSI shall immediately set up
         and license, at CCSI's cost, a Third Party source of Product under the
         procedure set forth in Section 7.7 above except in this case the Third
         Party shall be a vendor to GE, provided the Third Party license is
         limited to manufacture and sale of Products solely to GE at the
         Discount Price and not to Third Parties. In the event the Third Party
         source of supply established above under clause (a) as a vendor to CCSI
         fails to supply GE with Product in a timely fashion pursuant to this
         Agreement, then GE shall, upon written notice to CCSI, also have the
         right to have a Third Party Product vendor to GE established pursuant
         to the procedure set forth in the preceding sentence.

13.5.    Effect of Termination.  Termination of this Agreement shall not relieve
         ---------------------
         the parties of any obligation  accruing prior to such termination.  The
         provisions  of  Sections  9.1,  9.2 and  this  13.5,  and  Articles  10

         shall survive the termination of this Agreement.  Each party shall bear
         its own termination costs. There will be no liquidated damages.

13.6.    Termination  by Market  Segment.  Any right to terminate this Agreement
         -------------------------------
         under this  Article 13 may,  at the  election  of the party  seeking to
         terminate, be exercised as to one or more individual Market Segments as
         specified in such party's written notice of termination. In such event,
         this  Agreement  shall continue in full force an effect with respect to
         the remaining Market Segments.

         including attorneys fees and costs (all "Liabilities") arising out of
         any breach of a representation or warranty contained in Section 2
         hereof, negligence, recklessness or intentional wrongful acts or
         omissions of the indemnifying party, its Affiliates or sublicensees in
         connection with the work performed by such party during the term of

         liable to the other for any indirect, incidental or consequential
         damages arising out of any terms or conditions in this Agreement or
         with respect to the performance thereof.

14.2.    Procedure. A party (the "Indemnitee") that intends to claim
         ---------
         indemnification under this Article 14 shall promptly notify the other
         party (the "Indemnitor") of any Liability or action in respect of which
         the Indemnitor or any of its Affiliates intend to claim such
         indemnification, and the Indemnitor shall have the right to participate
         in, and, to the extent the Indemnitor so desires, jointly with any
         other Indemnitor similarly noticed, to assume the defense thereof with
         counsel selected by the Indemnitor. The indemnity obligations under
         this Article 14 shall not apply to amounts paid in settlement of any
         loss, claim, damage, liability or action if such settlement is effected
         without the consent of the Indemnitor, which consent shall not be
         withheld unreasonably. The failure to deliver notice to the Indemnitor
         within a reasonable time after the commencement of any such action, if
         materially prejudicial to its ability to defend such action, shall
         relieve such Indemnitor of any liability to the Indemnitee under this
         Article 14, but the omission so to deliver notice to the Indemnitor
         will not relieve it of any liability that it may have to any Indemnitee
         otherwise than under this Article 14. The Indemnitor may not settle the
         action or otherwise consent to an adverse judgment in such action that
         diminishes the rights or interests of the Indemnitee without the
         express written consent of the Indemnitee. The Indemnitee, its
         employees and agents, shall cooperate fully with the Indemnitor and its
         legal representatives in the investigation of any action, claim or
         liability covered by this indemnification at Indemnitor' s expense.

                                  ARTICLE 15
                                  ----------

                                EXCUSABLE DELAY
                                ---------------

Neither party shall be held liable or responsible to the other party nor be
deemed to have defaulted under or breached this Agreement for failure or delay
in fulfilling or performing any term of this Agreement to the extent, and for so
long as, such failure or delay is caused by or results from causes beyond the
reasonable control of the affected party including but not limited to fire,
floods, embargoes, war, acts of war (whether war be declared or not),
insurrections, riots, civil commotions, strikes, lockouts or other labor
disturbances, acts of God or acts, omissions or delays in acting by any
governmental authority or the other party. The foregoing shall be subject to the
delayed party using reasonable efforts to mitigate the adverse consequences of
such delay.

                                  ASSIGNMENT
                                  ----------

This Agreement may not be assigned or otherwise transferred, nor, except as
expressly provided hereunder, may any right or obligations be assigned or
transferred by either party without the consent of the other party; provided
further, however that (i) each party may assign its rights and interests, and
delegate its obligations, hereunder, effective upon written notice thereof, to
any Affiliate, and (ii) either party may assign its rights and interests, and
delegate its obligations, hereunder, effective upon written notice thereof, to
any Third Party which acquires all or substantially all of the assets of CCSI or
GE, as the case may be, or which is the surviving third party in a merger or
consolidation with CCSI or GE as the case may be, if such Third Party assumes
all of the obligations of CCSI or GE, as the case may be, hereunder. Subject to
the foregoing, any reference to CCSI or GE hereunder shall be deemed to include
the successors thereto and assigns thereof. Notwithstanding anything to the
contrary contained in this Article 16, if, without GE's prior written consent,
either (a) CCSI assigns or otherwise transfers its rights and interests under
this Agreement to any Competing Manufacturer (defined below) including any
transfer by merger or asset sale; or (b) any Competing Manufacturer purchases or
otherwise obtains a controlling ownership interest (defined as 50% or more
ownership interest) in CCSI; then this Agreement shall terminate upon GE's
election and written notice thereof to CCSI, and such termination shall be
deemed a termination for cause under Section 13.1, resulting in the consequences
to the parties described in Section 13.4. For the purposes of this Agreement,
"Competing Manufacturers" shall mean only companies that design, manufacture and
sell gas turbines of greater than 2 MW for power generation or mechanical drive
applications. Further, in the event the assignment or transfer of rights under
clause a) above or the sale or transfer of controlling interest under clause b)
above are to a company (other than a Competing Manufacturer) that designs,
manufactures and sells gas turbines of greater than 2 but less than 70MW for
power generation or mechanical drive applications (herein "Other Turbine
Manufacturer") then the Parties hereby agree that GE has the right after good
faith consideration of any CCSI concerns, to Terminate under Section 13.1 with
consequences set forth in Section 13.4. Notwithstanding the foregoing, GE may
assign its rights and obligations with respect to intellectual property to GE
Power Systems Licensing, Inc., a wholly-owned subsidiary of GE.

                        ------------------------------

1.  APPLICABLE TERMS AND CONDITIONS. Purchaser and Seller agree that the
following statement shall be printed on the front of any Purchase Order or
Contract for the sale of XONON Modules or XONON Components (herein referred to
individually or collectively as the "Product" or "Products" or "Goods"): "The
purchase and sale of the Products set forth in this Purchase Order shall be
subject to the Terms and Conditions of Purchase attached as Exhibit C to the
Collaborative Commercialization and License Agreement (the "CCLA"), dated
November 19, 1998, between Catalytica Combustion Systems, Inc., (the "Seller")
and General Electric Company (the "Purchaser"). Any other terms and conditions
included in this Purchase Order or in any acknowledgment of this Purchase Order
shall not be applicable to this purchase and sale of Products.

2. PRICES AND PAYMENTS. Unless otherwise stated on the face of this Purchase
Order, Seller shall invoice Purchaser for one hundred percent (100%) of the
purchase price within thirty (30) days after delivery. Purchaser shall remit
full payment of the purchase price to Seller by wire transfer within forty five
(45) days of receipt of Seller's invoice. All prices specified here in are firm

necessary information including but not limited to a full description of the
goods ordered, the quantity ordered and requested delivery dates. All Purchase
Orders shall be placed as firm orders for goods setting forth the quantities of
goods required and the requested delivery date(s). Purchaser shall endeavor to
place purchase orders not later than one hundred and twenty (120) days prior to
the requested delivery date. Provided Purchaser has complied with the foregoing
one hundred and twenty (120) day prior notification, and except to the extent
caused by an Excusable Delay as defined in Article 15 of the CCLA, Seller shall
be liable for liquidated damages for failure to achieve delivery on or prior to
Purchaser's designated delivery date at the rate of 0.5% of the purchase price
allocable to the delayed goods per day (beginning with the fifteenth (15) day

percent 10% of Purchase Order purchase price. Purchaser shall waive such
liquidated damages if Purchaser's contract with its customer does not include a
provision for delay liquidated damages between Purchaser and its customer or if
Seller is able to remedy its delay at its sole cost such that Purchaser does not
incur any delay liquidated damages to its customer arising out of the delay of
the Products. If Seller is more than sixty (60) days late, Purchaser shall have
the right to terminate this Purchase Order.

affixed or attached thereto, shall be and remain the personal property of
Purchaser. Such property and, whenever practical, each individual item thereof,
shall be plainly marked or otherwise adequately identified by Seller as the
property of the Purchaser and shall be safely stored separate and apart from
Seller's property. Seller shall not substitute any property for Purchaser's
orders. Such property, while in Seller's custody or control, shall be held at
Seller's risk, shall be kept insured by Seller at Seller's expense in an amount
equal to the replacement cost with loss payment to Purchaser and shall be
subject to removal at Purchaser's written request, in which event Seller shall

being applicable to this Purchase Order, or other mutually agreed upon
specifications; (b) method of packing; (c) time of delivery; (d) the amount of

its supplier, Seller, without additional charge, shall provide all reasonable
