Article 3 – Key Terms

3.1 During the Term, Buyer agrees to purchase and receive, or cause to be received, and Seller agrees to sell and deliver, no less than the Minimum Annual Contract Quantity at the Delivery Point at the price set forth herein.

3.2 Seller and Buyer agree that all obligations of Buyer under this Agreement to purchase and take delivery of the Minimum Annual Contract Quantity shall be on a “take or pay” basis, such that Buyer shall pay for and receive, or cause to be received by a third party, or pay for even if not taken, all SAF delivered (or tendered for delivery, in the case of SAF not taken) by Seller to Buyer at the Delivery Point under this Agreement up to the Minimum Annual Contract Quantity, on condition that, in tendering such SAF, Seller has complied in all material respects with its obligations hereunder and subject to the conditions herein, including without limitation with all specifications stipulated for the SAF, its blending and blended output.

3.3 SAF Specifications. The physical specification for blended SAF delivered by Seller to Buyer pursuant to this Agreement is fuel compliant with ASTM Standard Specification D1655. The physical specification for unblended SAF purchased by the Buyer pursuant to this Agreement is D7566 Annex 5, “Standard Specification for Aviation Turbine Fuel Containing Synthesized Hydrocarbons” as in effect on the Effective Date.

Article 4 – Pricing; Contingency Account

4.1 Pricing shall be as set forth in this Article 4. [*****].

4.2 The price for SAF sold to Buyer hereunder will be [*****].

4.3 Delivery and Blending Costs shall be payable as set forth in Article 6.

4.4 In lieu of providing credit support hereunder, the Parties have agreed that Buyer will pre-fund an account for [*****] days of SAF deliveries hereunder. Accordingly, prior to the Completion Date Seller shall establish an account (the “Contingency Account”) which shall be available to pay any amounts due and owing by Buyer hereunder in the event that Buyer fails to make payment when due on any undisputed invoice issued hereunder. Within ten (10) days of Buyer receiving from Seller the notice of Commencement Date in accordance with Section 2.9 and a report by a mutually agreed independent engineer that the Seller’s Facilities are complete and [*****] away from the Commencement Date, Buyer shall pay to the Contingency Account by wire transfer of immediately available funds an amount equal to the price that would be due and payable for [*****] U.S. Gallons of SAF if such SAF were delivered on the Completion Date (i.e., using the pricing formula in Section 4.2 above). If at any time the balance in the Contingency Account is more than ten percent (10%) greater than what would be required to fund the Contingency Account for the next [*****] days (based upon the pricing then in effect under Section 4.2 for [*****] U.S. Gallons of SAF), Seller shall apply a credit in the amount of such excess on the next invoice issued hereunder. If at any time the balance in the Contingency Account is more than ten percent (10%) less than what would be required to fund the Contingency Account for the next [*****] days (based upon the pricing then in effect under Section 4.2 for [*****] U.S. Gallons of SAF), Seller shall invoice Buyer for such deficiency and Buyer shall promptly (but in no event later than five (5) Business Days after receipt of Seller’s invoice) fund to the Contingency Account by wire transfer of immediately available funds an amount equal to such deficiency. Seller agrees to apply all deposits in the Contingency Account solely towards payments due by Buyer hereunder; provided that notwithstanding anything to the contrary herein, Seller shall have the right to pledge, hypothecate, or assign the Contingency Account and any cash or assets on deposit in, or credited to, such account, free from any claim or right of any nature whatsoever of Buyer. For sake of clarity, in the event that Seller draws on the Contingency Account in order to pay an invoice due and owing by Buyer hereunder, such payment shall not constitute a cure of any Event of Default under Section 11.1 of the General Terms and Conditions unless and until Buyer shall have remedied any deficiency in the Contingency Account resulting therefrom. After the end of the Term and the resolution of all outstanding amounts due and owing hereunder, Seller shall transfer the balance in the Contingency Account to Buyer.

6.4 Seller shall further be responsible for securing all permissions and authorizations needed for the blending of the SAF with conventional Jet A Fuel and for the conduct and output of such blending according to the standards and specifications agreed herein. Without prejudice to the generality of the foregoing and without the scope of the foregoing being deemed reduced, Seller shall also be responsible for securing recertification / approval of the blended output, including product gains recertification, after blending.

For sake of clarity, while the Parties recognize that SAF delivered hereunder will be a blended mix of Jet A Fuel and unblended SAF, for all volumes of blended SAF delivered hereunder by Seller, Seller shall have delivered to the applicable Off-Airport Storage Facility for blending with Jet A Fuel an equivalent volume (at 15 degrees Celsius) of unblended SAF. If Seller makes available to Buyer SAF in excess of the Minimum Annual Contract Quantity, Buyer shall have the right to purchase such SAF on the same terms and conditions as set forth herein other than with respect to price, which will be subject to written agreement of the Parties. For sake of clarity, Buyer shall have no obligation pursuant to this Agreement to purchase any SAF in excess of the Minimum Annual Contract Quantity, and Seller shall have no obligation to provide such SAF. All sales of SAF by Seller in excess of the Minimum Annual Contract Quantity shall be on an As Available Basis, and Seller shall have no obligation to offer any SAF to Buyer in excess of the Minimum Annual Contract Quantity even if Seller has such SAF available. If, for any reason, Seller’s Facilities are incapable of producing sufficient SAF to deliver the Minimum Annual Contract Quantity of SAF, then Seller shall allocate the SAF produced from Seller’s Facilities ratably among all of Seller’s customers without discrimination; provided that Seller shall have no obligation to allocate to Buyer production from the facilities currently under development by Seller known as Net-Zero 1 and Net-Zero 2. Seller shall use commercially reasonable efforts to develop sufficient capacity at Seller’s Facilities to ensure delivery of the Minimum Annual Contract Quantity.

2. REPRESENTATION & COMPLIANCE WITH APPLICABLE LAW.

Each Party represents and warrants to the other Party as of the Effective Date, and shall be deemed to represent and warrant as of the date of any purchase of SAF hereunder, that:

a) it is duly organized and validly existing under the laws of the jurisdiction of its organization or incorporation and, if relevant under such laws, in good standing, has the power to execute and deliver this Agreement and any other related documentation that it is required by this Agreement to deliver and to perform its obligations under this Agreement, and has taken all necessary action to authorize such execution, delivery and performance;

b) such execution, delivery and performance do not violate or conflict with any Applicable Law(s) in any material respect, any provision of its constitutional documents, order or judgment of any court or Governmental Authority or, in any material respect, any of its assets or any contractual restriction binding on or affecting it or any of its assets;

c) its obligations under this Agreement constitute its legal, valid and binding obligations, enforceable in accordance with their respective terms (subject to applicable bankruptcy, reorganization, insolvency, moratorium or similar laws affecting creditors’ rights generally and subject, as to enforceability, to equitable principles of general application regardless of whether enforcement is sought in a proceeding in equity or at law);

d) it is not relying upon any representations of any other Party other than those expressly set forth in this Agreement;

e) is not bound by any agreement that would preclude or hinder its execution, delivery, or performance of this Agreement; and

f) neither it nor any of its Affiliates has been contacted by or negotiated with any finder, broker or other intermediary in connection with the sale of SAF hereunder who is entitled to any compensation with respect thereto.

3. SPECIFICATIONS AND REQUIREMENTS

3.1 Seller warrants that the unblended SAF produced shall comply with ASTM Standard Specification D7566 Annex 5, “Standard Specification for Aviation Turbine Fuel Containing Synthesized Hydrocarbons” at the time of blending of the SAF at the Off-Airport Storage Facility. Seller further warrants that prior to the time of delivery Seller shall secure the applicable recertification or approval of the blended SAF output and that at the time of delivery at the Delivery Point such blended SAF output shall comply with ASTM Standard Specification D1655.

3.2 Any other supply specification requires approval by Buyer and a complete specification must be attached to the Agreement.

3.3 EXCEPT AS SPECIFICALLY PROVIDED IN SECTION 3.1, THERE ARE NO GUARANTEES OR WARRANTIES HEREIN, EXPRESS OR IMPLIED, AS TO THE MERCHANTABILITY, FITNESS OR SUITABILITY OF THE FUEL FOR ANY PARTICULAR PURPOSE OR OTHERWISE.

3.4 Seller’s Intellectual Property Infringement Indemnity.

a) If an action is brought or threatened against Buyer claiming that Buyer’s use, as permitted herein, of the SAF infringes any Intellectual Property rights arising or existing under Applicable Law, Seller shall defend, indemnify and hold harmless the Buyer Indemnitees from and against any and all Claims and Losses of Buyer and its Affiliates to the extent arising from such action or claim.

Fuel Sales Agreement Annex I | Page 4

Confidential

b) If Buyer’s permitted use of the SAF is materially impaired, Seller shall use commercially reasonable efforts, at its expense, to continue its supply obligations under this Agreement, including at its own election and expense (i) to substitute an equivalent non-infringing product for the allegedly infringing SAF, (ii) to modify the allegedly infringing SAF so that it no longer infringes but remains functionally equivalent or better or (iii) to obtain for Buyer the right to continue using such SAF; provided, however, that in all cases the SAF shall comply with the specifications set forth in Section 3.1 above. Seller shall, prior to proceeding with any of the foregoing actions, consult with Buyer as to the proposed action and consider in good faith any reasonable request of Buyer in respect thereof. Nothing herein constitutes a guarantee by Seller that such efforts will succeed in avoiding the infringement claim or that Seller will be able to replace the infringing SAF with a product of comparable functionality or effectiveness. If Seller reasonably believes that an injunction against use of the SAF may be granted against Buyer, either imminently or with the passage of time, Seller may at its expense, and upon reasonable prior written notice to Buyer, take any of the foregoing actions in order to minimize its liability.

c) This Section 3.4 does not apply to, and Seller assumes no liability with respect to, Claims and Losses for patent infringement or copyright infringement or improper use of other proprietary rights (including any license or Intellectual Property, whether by way of copyright or otherwise) to the extent that such Claims or Losses relate, in whole or in part, to (i) Buyer’s modification or alteration of the SAF (except to the extent permitted by this Agreement), made without Seller’s written consent or contrary to Seller’s instructions, or (ii) the combination of the SAF with other products or materials after the Delivery Point, other than the combination of the SAF with other fuel meeting the ASTM Standard Specification D1655 while in storage at the on-airport storage facility.

d) The foregoing provisions of this Section 3.4 state the entire liability and obligations of Seller and its Affiliates, and the exclusive remedy of the Buyer Indemnitees, with respect to any actual or alleged infringement of patents, copyrights, trademarks or other Intellectual Property by the SAF sold and delivered hereunder.

e) Buyer shall promptly notify Seller in writing following receipt of written notice of any claims alleging infringement of patents or other proprietary rights (including Intellectual Property) in connection with Buyer’s permitted use of the SAF or Seller’s performance of its supply obligations under this Agreement, and shall provide Seller with all information in its possession relevant to such claim.

3.5 If an action is brought or threatened against Seller claiming that any condition or event described in Section 3.4(c) results in an infringement upon any Intellectual Property arising or existing under Applicable Law, Buyer shall defend, indemnify and hold harmless the Seller Indemnitees at Buyer’s expense from and against any and all Claims and Losses of Seller Indemnitees to the extent arising from such action or claim.

3.6 Seller shall:

a) [*****];

b) [*****];

c) [*****]; and

d) [*****].

e) [*****].

4. QUALITY

4.1 Seller must ensure that SAF is not contaminated at the Delivery Point. For this purpose, and subject to the remaining provisions of the Agreement, Seller shall ensure that the policies, standards, procedures and any other practices recommended in ICAO Doc 9977 are implemented and complied with by the Seller, Seller’s Agents, suppliers, operators and any other parties engaged in the operation and/or the supply of SAF.

5. DELIVERY & EMISSIONS CREDITS

5.1 Title to and risk of loss of the SAF shall pass to Buyer at the Delivery Point.

5.2 Seller’s measurement, independently verified by the Off-Airport Storage Facility, shall be accepted as prima facie evidence of the quantities of SAF delivered, but Buyer shall be entitled to check the accuracy of the instruments used by Seller upon reasonable notice during Seller’s normal operating hours in the presence of Seller’s representative. Determinations of quantities made in accordance with international industry practice shall be binding. For the avoidance of doubt, the blended SAF quantity delivered shall be equivalent in volume at 15 degrees Celsius as the quantity of unblended SAF purchased.

5.3 Any SAF delivered under the Agreement which is found to be Off-Specification SAF or Contaminated SAF may be rejected by Buyer, at Buyer’s sole discretion. Buyer shall not be required to pay Seller for any Off-Specification SAF or Contaminated SAF rejected by Buyer hereunder, or for any output rejected by Buyer that is not SAF in accordance with the specification set out in Clause 3.1.

5.4 Without prejudice to Seller’s other obligations and Buyer’s rights under this Agreement, Seller shall pro-actively take reasonable steps to keep informed, and will use its best endeavors to ensure that Buyer is notified as soon as practicable

a) of any matter that could reasonably be expected to impact Seller’s ability to supply Buyer in accordance with the Agreement; Seller will provide Buyer with relevant information regarding the matter and any Seller planned actions to minimize any impact on Buyer, and in the case of any disruption to supply, provide daily updates or relevant information in writing until the supply disruption is resolved; and

b) of any infrastructure works which Seller may be aware of and which potentially may impact available supply to the Buyer.

5.5 The Parties shall reasonably cooperate to establish a mutually agreeable monthly delivery schedule for SAF to be delivered hereunder, taking into account the capabilities of Seller’s Facilities and Seller’s obligations to its other customers, it being the expectation that such schedule shall provide for delivery of the Minimum Annual Contract Quantity substantially on a ratable basis, provided that Buyer may request a reasonable variation to the monthly amount with sixty (60) days’ advance written notice (but without limiting Buyer’s obligation to take and pay for the Minimum Annual Contract Quantity for the year in question).

Fuel Sales Agreement Annex I | Page 6

Confidential

5.6 The Parties acknowledge that as of the date hereof there are various Emissions Credits and User-Specific Credits related schemes or programs currently under consideration (e.g., CORSIA and the Renewable Energy Directive) but which have not yet been finalized. On or before the Completion Date, Seller agrees to obtain, at Seller’s cost and expense, a Sustainability Certification with respect to Seller’s Facilities. In addition, by the later of: (i) the Completion Date, and (ii) the date CORSIA goes into effect, Seller shall cause the SAF to be certified as an eligible fuel for participation in CORSIA. If Seller has not caused the SAF to be certified as an eligible fuel for participation in CORSIA within the time frame set forth in the preceding sentence despite having employed commercially reasonable efforts, Seller shall have an additional six (6) month period to cure such failure. If Seller has not obtained such certification under CORSIA within such six (6) month cure period, Buyer shall have the right to terminate the Agreement on twenty (20) days’ written notice to Seller, without any further liability of either Party arising out of such termination. After obtaining the same, Seller shall maintain such Sustainability Certification and certification under CORSIA for the duration of the Delivery Term. If, for any reason, the SAF does not qualify as a CORSIA eligible fuel, the purchase price for the SAF shall be reduced by the portion of the economic value of the applicable credits that Buyer otherwise would have received under such programs pursuant to this Agreement. Notwithstanding the previous sentence, if the SAF subsequently becomes eligible for CORSIA, the reduction in purchase price for the SAF in connection with such initial ineligibility shall no longer apply. To the extent the subsequent eligibility entitles the SAF to earn any applicable credits retroactively, Seller may adjust such reduction in price retroactively by a corresponding amount.

5.7 If the Seller can provide waste or residue based SAF that (a) complies with the UK’s definition of a development fuel, (b) meets its associated sustainability requirements and (c) the UK User-Specific Credit value is greater than the CORSIA traded value, then the Buyer shall claim for the UK User-Specific Credit value and once received pass back to the Seller the value of such UK User-Specific Credit minus the higher of (i) the CORSIA value and (ii) $[*****] of unblended SAF.

5.8 [*****].

5.9 In the event of a change in Applicable Law that materially affects the availability of Emissions Credits or Blenders Tax Credits or the process for obtaining Emissions Credits or Blenders Tax Credits, then the Parties shall work in good faith to renegotiate the commercial or operational terms of this Agreement in order to preserve the economic value of this Agreement and the allocation of responsibilities set forth herein.

6. INSPECTIONS, AUDITS AND SAMPLES

6.1 Buyer or its representative shall have the right to perform a (technical) survey, audit or inspection of Seller’s records on (a) the SAF quality and quality control and (b) the sustainability attributes of the SAF and (c) checks of the SAF production quantities produced at the Supplier’s Facility. The records set forth in this Section 6.1 shall be made available for inspection or survey, as the case may be, by Buyer at Seller’s Facility. A (technical) survey or inspection shall be made during normal working hours. Buyer shall give reasonable notice of its intention to perform a technical survey or inspection as provided in this Section 6.1, and shall use its best endeavors not to hinder, delay or disrupt Seller’s activities.

6.2 Buyer or its representative shall have the right to obtain samples of the SAF intended to be delivered to Buyer in accordance with the Agreement, to be taken by Seller or Seller’s representative with Buyer having the right to be present. Buyer shall give Seller reasonable advance notice of its intention to obtain samples.

7. COMPLAINTS & CLAIMS

7.1 Complaints as to delays shall be notified to Seller at the time of delivery or as soon as practicable thereafter, followed by a written claim to be made within fifteen (15) days after delivery.

Fuel Sales Agreement Annex I | Page 7

Confidential

7.2 Complaints as to defects in quality or any other matter shall be notified to Seller as soon as practicable, followed by a written claim to be made within thirty (30) days after delivery.

7.3 If the claim is not made within either the 15-days period or the 30-days period, respectively, it represents a waiver of the right to claim. In no event is a waiver of the right to claim made or implied by a signature or any other statement on the Delivery Note, irrespective of whether or not such Delivery Note contains conditions implying such waiver.

8. DUTIES, TAXES AND CHARGES

8.1 Buyer shall pay any taxes, fees or other charges, imposed by any national, local or airport authority on the delivery, sale, inspection, storage and use of SAF, except for taxes on Seller’s income and taxes on raw material. To the extent allowed, Seller shall show these taxes, fees and other charges as separate items on the invoice for the account of Buyer.

8.2 Seller shall keep Buyer informed at all times about the taxes, duties and charges existing or to be charged to Buyer. Should Seller, however, in good faith provide inaccurate or incomplete information to Buyer, Buyer shall not be relieved of the obligation to pay. Buyer may, or at Buyer’s request, Seller shall, as an applicable nominal party, take all actions necessary to contest the validity, applicability or any other like challenge with respect to the amount or application of such taxes, duties and charges (including but not limited to withholding of any tax) and shall institute actions to recover past or anticipated payments thereof, provided, as to withholding of any tax, that Buyer gives Seller an indemnity which meets any reasonable requirement of Seller. Unless other arrangements are made, all actions taken in this respect shall be at Buyer’s sole expense. If Buyer is entitled to purchase any SAF sold pursuant to the Agreement free of any taxes, duties or charges, Buyer shall deliver to Seller a valid exemption certificate for such purchase.

9. FORCE MAJEURE

9.1 In addition to any waivers (arising out of the same or other causes) provided by operation of law, no failure or omission by either Party to carry out or observe any of the provisions of the Agreement (except for Section 9.6 hereunder) shall give rise to any claim against that Party, or be deemed to be a breach of the Agreement, if the same shall arise out of a Force Majeure event. A Force Majeure event for the purposes of this Agreement means any cause not within the reasonable control of the Party claiming Force Majeure (whether or not foreseeable) and not occasioned by such Party’s fault or negligence that prevents or delays, in whole or in part, such Party’s performance of one or more of its obligations under this Agreement. Provided that they satisfy the foregoing requirements, Force Majeure events may include such causes as labor disputes, strikes, governmental intervention, or the Party’s response to the insistence of any governmental instrumentality or Person purporting to act therefore, terrorism, wars, civil commotion, hijacking, fire, flood, accident, storm or any act of God.

9.2 Notwithstanding the provisions of Section 9.1, neither Party shall be relieved by reason of Force Majeure of any obligation to make payment under the Agreement. Neither the ability of Buyer to obtain better economic terms for SAF from an alternative supplier, nor any cost increase resulting from a circumstance that in itself is not a Force Majeure event, however substantial, in Seller’s performance of the Agreement, as applicable, shall constitute Force Majeure. The default of a sub-supplier or subcontractor shall not constitute a Force Majeure event (except to the extent the sub-supplier or subcontractor is affected by a Force Majeure event).

9.3 The Party affected by the Force Majeure shall use all reasonable endeavors to remove such reasons or mitigate the effects thereof, and upon removal and remedying of such reason said Party shall promptly resume the performance of its obligations, provided, however, that, in removing such reasons or mitigating such efforts, a Party shall not be required to settle strikes or lockouts or government claims by acceding to any demands when, in the discretion of that Party, it would be inappropriate to do so.

Fuel Sales Agreement Annex I | Page 8

Confidential

9.4 If deliveries are delayed, hindered or prevented due to Force Majeure on Seller’s part, Buyer shall be free to purchase replacement jet fuel from third parties during such period.

9.5 Buyer shall be released from the obligation to receive and/or pay for any SAF not provided or made available by Seller to Buyer due to a Force Majeure.

9.6 In the duration of any Force Majeure event affecting Seller, Seller shall be entitled to apportion the remaining capacity of SAF as it sees fit, albeit in an equitable and non-discriminatory manner.

9.7 If an event of Force Majeure affecting Seller occurs, and such event of Force Majeure wholly prevents Seller from making available any SAF hereunder to Buyer, Seller may, in its sole discretion, notify Buyer of Seller’s extension of the Term by a number of days equal to the period from the day such event of Force Majeure took effect until the end of such event of Force Majeure, on condition that such extension of the Agreement is also acceptable to the Buyer.

10. LIABILITY AND INDEMNITY

10.1 Buyer shall indemnify, defend, hold and save harmless the Seller Indemnitees from and against any and all Claims and Losses of Third Parties for loss of or damage to any property whatsoever or for injury, including fatal injury, and death to any person whatsoever that arise out of or are connected with actions or omissions in the performance by Buyer of its obligations under this Agreement, or that arise out of or are connected with the handling, storage, sales, transportation, use, misuse, blending, processing or disposal by or on behalf of Buyer, Buyer’s customers, or their respective Affiliates or their contractors or carriers of any tier, of any SAF after such SAF has been delivered to the Delivery Point, except in each case to the extent caused by Seller’s breach of the Agreement, or the negligence or willful misconduct of Seller or any Seller Indemnitee.

10.2 Seller shall indemnify, defend and save harmless the Buyer Indemnitees from and against any and all Claims and Losses of Third Parties for loss of or damage to any property whatsoever or for injury, including fatal injury, and death to any person whatsoever that arise out of or are connected with actions or omissions in the performance by Seller of its obligations under this Agreement, or that arise out of or are connected with the handling, storage, sales, transportation, use, misuse, blending, processing or disposal by or on behalf of Seller or its Affiliates or their contractors or carriers of any tier, of any SAF prior to the time such SAF has been delivered to the Delivery Point, except in each case to the extent caused by Buyer’s breach of the Agreement, the negligence or willful misconduct of Buyer or any Buyer Indemnitee.

10.3 The liability of Seller for any loss, damage, claim or other expenditure arising from Seller failing to perform its obligations under the Agreement shall be limited to the prompt refund of the price of an affected delivery or (at Seller’s option), the replacement of affected SAF at no additional cost to Buyer. The preceding sentence and limitations shall not apply in relation to any indemnities owed by the Seller to the Buyer, including under preceding Section 10.2.

10.4 Notwithstanding anything to the contrary in these General Terms and Conditions or the Agreement, neither Party shall, under any circumstances, be liable to the other Party for consequential, incidental, special, punitive, or exemplary damages arising out of or related to the transactions contemplated under this Agreement, including, but not limited to, lost profits or loss of business, or business interruption damages, even if apprised of the likelihood of such damages occurring, and regardless of whether available in tort or agreement or by statute. These limitations shall apply even if it causes a remedy in this Agreement to have failed of its essential purpose. the limitations of this Section 10.4 shall not prevent the recovery through the indemnification provisions of this Article 10 of consequential, incidental, special, punitive, or exemplary damages suffered by and paid to a Third Party by an indemnified Party (excluding Third Party customers of an indemnified Party) as a result of actions included in the protection afforded by the indemnification provisions of Article 10.

11. DEFAULTS AND REMEDIES; TERMINATION

11.1 A Party shall be deemed to be in default hereunder if any of the following events occur (each of the following events to be referred to as an “Event of Default”, the Party in default to be referred to as the “Defaulting Party” and the Party not in default to be referred to as the “Non-Defaulting Party”):

a) The failure to make, when due, any payment required pursuant to this Agreement if such failure is not remedied within thirty (30) days after written notice thereof;

b) In case of a material breach (or a number of breaches that collectively constitute a material breach, including any continuous or persistent breaches) of the Agreement by the other Party, but only insofar as the other Party has not cured its breach of the Agreement within sixty (60) days of receiving written notice of the default from the first Party, provided that if such sixty (60) day period is not sufficient to enable the remedy or cure of such failure in performance, and such Party shall have upon receipt of the initial notice promptly commenced and diligently continues thereafter to remedy such failure, then such Party shall have a reasonable additional period of time not to exceed an additional sixty (60) day period;

c) If the other Party becomes insolvent, makes a general assignment for the benefit of its creditors or commits an act of bankruptcy or if a petition for its reorganization or readjustment of its indebtedness is filed by or against it and, in the case of any such petition filed against it, such petition is not dismissed within ninety (90) days, or if a receiver, trustee or liquidation of all or substantially all of its property is appointed;

d) Any representation or warranty made by such Party herein is false or misleading in any material respect when made or when deemed made or repeated; or

e) For the benefit of Seller, if Buyer fails to satisfy the creditworthiness/collateral requirements of this Agreement and such failure continues for fifteen (15) Business Days after written notice thereof.

Notwithstanding the foregoing, a Party shall not be in default of its obligations hereunder to the extent such failure is, and to that extent only, (i) caused by or is otherwise attributable to a breach by the other Party of its obligations under this Agreement, or (ii) occurs as a result of a Force Majeure event declared by a Party in accordance with this Agreement.

11.2 If either Party reasonably believes that an event has occurred which, if not remedied within the applicable cure period explicitly set forth in Section 11.1 above, would result in an Event of Default by or affecting the other Party, the Non-Defaulting Party shall give the Defaulting Party a notice (a “Default Notice”), which shall specify and provide particulars of the alleged Event of Default. If such Event of Default continues uncured following the cure period specified above for such Event of Default, then the Non-Defaulting Party shall have such remedies as may be available to it at law or in equity subject, however, to the limitations on liability provided herein. For clarity, this shall non-exhaustively include the right to forthwith terminate the Agreement on written notice to the Defaulting Party. If no cure period is specified in Section 11.1 for the Event of Default evoked by a Party, then occurrence of such Event of Default shall entitle the non-Defaulting Party to terminate this Agreement forthwith.

11.3 Notwithstanding early termination, each Party shall fulfil all obligations accrued under the Agreement prior to the time the termination becomes effective and shall not be released from antecedent/accrued rights or liabilities.

12. SUBCONTRACTING

Seller may, without prior consent of Buyer, subcontract the performance of its obligations under the Agreement in whole or in part to a third party, provided that Seller acknowledges and agrees that it shall be responsible to Buyer for the acts and omissions of its subcontractors to the same extent as Seller is responsible to Buyer for the acts or omissions of its own employees.

13. NON-WAIVER

No failure or delay of any Party (including their employees and Agents) to exercise any right or power under the Agreement or at law shall operate as a waiver thereof, except as expressly provided in the Agreement, nor shall any single or partial exercise of any such right or power preclude any other or further exercise thereof or the exercise of any other right or power under the Agreement, and no waiver of any Party of any provision or part of any provision of the Agreement shall be binding unless expressly confirmed in writing.

14. NON-DISCLOSURE

14.1 “Confidential Information” means any information disclosed by either Party to the other Party, directly or indirectly, in writing, orally, or by inspection of tangible objects (including documents, prototypes, samples, plant, and equipment), which is designated as “Confidential,” “Proprietary,” or some similar designation, or that should reasonably be understood to be confidential from the context of disclosure or nature of the information. Confidential Information will not, however, include any information that the receiving Party can show by competent evidence: (a) was publicly known and made generally available in the public domain prior to the time of disclosure by the disclosing Party; (b) becomes publicly known and made generally available after disclosure by the disclosing Party to the receiving Party through no action or inaction of the receiving Party; (c) is already in the possession of the receiving Party at the time of disclosure by the disclosing Party, as shown by the receiving Party’s files and records, except if so antecedently received by a Person in the context of the negotiation of this Agreement; (d) is obtained by the receiving Party from a third party without breach of the third party’s obligations of confidentiality; or (e) is independently developed by the receiving Party without use of or reference to the disclosing Party’s Confidential Information. For the avoidance of doubt, the Agreement, the information contained in the Agreement and the existence of the Agreement itself shall be considered Confidential Information. Each receiving Party shall keep the Confidential Information disclosed to it by the disclosing Party confidential, shall take all measures reasonably necessary to safeguard confidentiality (at any rate no less than those taken by a reasonable business for safeguarding its own highly sensitive commercial information), and shall not disclose such Confidential Information, in whole or in part, except to those of its directors, consultants, officers, and employees, Agents, consultants, advisors, affiliates and in the case of Seller, debt or equity finance parties providing or potentially providing financing to Seller or its Affiliates (i) who need to know such Confidential Information for the purpose of this Agreement or for potentially entering into this Agreement, (ii) who have been informed of the confidential nature of such information, and (iii) who are obligated to keep such information in confidence pursuant to terms of this Agreement.

14.2 In addition to the specific obligations otherwise set forth in this Agreement, the receiving Party shall:

a) safeguard and hold in confidence all such Confidential Information using efforts commensurate with those it employs for the protection of corresponding sensitive information of its own, which in any event shall not be a lesser standard than the type of efforts that would be taken by a reasonable business for the protection of its own highly sensitive information and trade secrets; and

b) not use such Confidential Information, directly or indirectly, for any purposes other than the performance of this Agreement and not use such Confidential Information for the receiving Party’s own benefit or for any purpose detrimental to the interests of the disclosing Party.

Fuel Sales Agreement Annex I | Page 11

Confidential

14.3 However:

a) Each Party is allowed to disclose Confidential Information to any governmental or supranational authority or to make any public disclosures to the extent disclosure is legally compulsory, provided, however, that, to the extent permitted by law, such Party shall inform the disclosing Party of such governmental request for information or regulatory obligation to disclose with advance written notice; and

b) The Buyer is allowed to disclose information of any findings resulting from any audit, investigation or inspection conducted under this Agreement to members and directors of IATA, IFQP, JIG and other fuel quality organizations the Buyer may be a member of, where such findings relate to a safety of flight issue for the Buyer and/or other aircraft operators.

14.4 In the event of a contested disclosure, the burden of demonstrating that the information in issue was not confidential shall be borne by the Party having received the same.

14.5 Each Party undertakes that, should it commit any breach of its confidentiality obligations under this Agreement, it will take all reasonable measures to remedy the breach. Each Party agrees that money damages may not be a sufficient remedy for any breach of the confidentiality obligations in this Agreement, and each Party shall be entitled to seek injunctive or other equitable relief to remedy or forestall any such breach or threatened breach.

14.6 Nothing in this Agreement is intended to or shall be construed as granting to any Party any license or right under any patent, copyright, or other intellectual property right of the other Party, nor shall this Agreement impair the right of any Party to contest the scope, validity, or alleged infringement of any patent or copyright. This Agreement shall not grant any Party any rights in or to the Confidential Information of the other Party, except as expressly set forth in this Agreement.

15. NOTICES

15.1 All notices and communications required to be given pursuant to this Agreement shall be:
