6.2(b), or Subsection 6.2(c), as applicable, less the aggregate amount of any negative Exclusivity Fee achieved during the preceding months of such Year and not otherwise set-off against such positive Methanol Exclusivity Fee in a preceding month
(in no event will the cumulative monthly Methanol Exclusivity Fees exceed [***] in any given Year).
| | ---- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



For greater certainty, the obligation of Methanex to pay the Methanol Exclusivity Fee, in any given month, is contingent upon the Cash Margin/Gallon or the Deemed Cash
Margin/Gallon, as the case may be, for such month being a positive number and the cumulative Cash Margin/Gallon or Deemed Cash Margin/Gallon, in any given Year, being a positive number.



Notwithstanding the foregoing, the maximum cumulative amount payable by Methanex to Terra in any given Year on account of the Methanol
Exclusivity Fees shall be [***] (Exclusivity Fee Cap), which amount shall be pro-rated for any period shorter than an entire Year. At the end of each Year (or a portion thereof, if applicable), the Parties will add the Positive
Margin amounts for those months in which a Positive Margin was achieved and the Negative Margin amounts for those months in which a Negative Margin was achieved.



In the event that the net amount after adding the Positive Margin amounts and the Negative Margin amounts, for any given Year, is a negative
number (Negative Result), then Terra shall reimburse Methanex for any Methanol Exclusivity Fees paid by Methanex to Terra on or before January 25thof the Year following the Year for which the calculation is made.



In the event that the net amount after adding the Positive Margin amounts and the Negative Margin amounts, for any given Year, is a positive
number (Positive Result), then Terra shall refund to Methanex the full amount of any Methanol Exclusivity Fees paid by Methanex to Terra in excess of the Positive Result (Excess Fees). Terra shall pay to
Methanex the full amount of any Excess Fees on or before January 25thof the Year following the Year for which the
calculation is made.



Methanex shall be entitled in its discretion to off-set
the full amount of any Excess Fees or any other amounts owing by Terra to Methanex under this Agreement, against any amounts owing by Methanex to Terra under this Agreement.



Sample calculations illustrating the calculation of the Methanol Exclusivity Fees are set forth in the attached Schedule F.



6.3. Combined Production Fees/Methanol Production Fees:In addition to the
Methanol Exclusivity Fees, Methanex shall pay the following fees to BMC in connection with the operation of the Beaumont Facility:

16.3. Indemnification Procedures: Within a reasonable period of time after a Terra
Indemnified Person or a Methanex Indemnified Person (whether one or more, an Indemnified Party) establishes a basis for or receives actual notice of any Claim covered by Subsection 16.1 or Subsection 16.2, as the case may be, the
Indemnified Person shall notify the Party from whom indemnification is sought (the Indemnifying Party) in writing of such Claim, provided, however, that the failure to so notify the Indemnifying Party shall not relieve the
Indemnifying Party from any liability which it may have to the Indemnified Person pursuant to Subsection 16.1 or Subsection 16.2, as the case may be, except to the extent of material detriment suffered by the Indemnifying Party as a result of such
failure. In the event that a Claim arises out of or results from matters with respect to third parties (a Third Party Claim), the Indemnifying Party shall undertake the defence thereof by attorneys chosen by it, which are
reasonably acceptable to the Indemnified Person. So long as the Indemnifying Party is defending any Third Party Claim actively and in good faith, the Indemnified Person shall not settle such Third Party Claim without the consent of the Indemnifying
Party.



16.4. Defence of Third Party Claim: If the Indemnifying Party,
within a reasonable time after notice of any Third Party Claim, fails to defend such Third Party Claim actively and in good faith, the Indemnified Party shall (upon further notice) have the right to undertake the defence, compromise or settlement of
such Third Party Claim or consent to the entry of a judgment with respect to such Third Party Claim, on behalf of and for the account and risk of the Indemnifying Party, and the Indemnifying Party shall thereafter have no right to challenge the
Indemnified Partys defence, compromise, settlement or consent to judgment. Irrespective of which Party has the right to defend, compromise or settle any Third Party Claim pursuant to this Subsection 16.4, each of the Indemnifying Party and the
Indemnified Party shall be entitled to consult with each other, to the extent it reasonably requests, in respect of the



- 25 -



---

defence of such Third Party Claim and shall cooperate in the defence of any such Third Party Claim, including making its partners (if applicable), officers,
directors, employees and books and records available for use in such Third Party Claim, and shall take those actions reasonably within its power which are reasonably necessary to preserve any legal defences to such matters, without the necessity of
formal subpoena or court action.



16.5. Payment: The Indemnifying Party
shall promptly pay each Indemnified Party any amount properly due under this Section 16 upon demand therefor and reimburse each Indemnified Party for all reasonable expenses (including reasonable attorneys fees and costs of court) for which
the Indemnified Party is entitled to be indemnified hereunder as they are incurred by such Indemnified Party. Upon judgment, determination, settlement or compromise of any Third Party Claim, the Indemnifying Party shall, upon demand therefor,
promptly pay on behalf of the Indemnified Party, and/or shall promptly reimburse the Indemnified Party for its payment of, the amount so determined by such judgment, determination, settlement or compromise and all other Claims of the Indemnified
Party with respect thereto, unless, in the case of a judgment or determination, an appeal is made therefrom; provided, however, that if the Indemnifying Party desires to appeal from an adverse judgment or determination, then the Indemnifying
Party shall post and pay the cost of the security or bond to stay execution of the judgment or determination pending appeal. Upon the payment in full by the Indemnifying Party of all of such amounts, the Indemnifying Party shall succeed to the
rights of the Indemnified Party, to the extent such rights are not waived in settlement, against the third party who made such Third Party Claim.



16.6. Limitation of Liability: NOTWITHSTANDING ANYTHING TO THE CONTRARY CONTAINED HEREIN, EXCEPT AS PROVIDED IN SUBSECTION 18.3(f) BELOW OR SECTION 4 OF SCHEDULE
B, NO PARTY, NOR ANY RESPECTIVE REPRESENTATIVE, SHALL BE LIABLE TO ANY OTHER PARTY FOR ANY CONSEQUENTIAL, INDIRECT, SPECIAL OR PUNITIVE DAMAGES FROM ANY CAUSE WHATSOEVER, WHETHER BASED IN CONTRACT, TORT (INCLUDING NEGLIGENCE), STRICT LIABILITY OR
ANY OTHER LEGAL THEORY UNLESS (I) SUCH DAMAGES RESULT FROM THE GROSS NEGLIGENCE OR INTENTIONAL MISCONDUCT OF SUCH PARTY OR ANY OF ITS REPRESENTATIVES; OR (II) SUCH DAMAGES ARE PAYABLE BY AN INDEMNIFIED PARTY PURSUANT TO A THIRD PARTY CLAIM MADE BY A
NON-AFFILIATE OF THE INDEMNIFIED PARTY AND FOR WHICH INDEMNIFICATION IS OTHERWISE AVAILABLE HEREUNDER.



|17. | FORCE MAJEURE
|--- | -------------



17.1. Force Majeure Event: If, as a result of the occurrence of a Force Majeure Event, a Party (after the exercise of reasonable diligence) is rendered unable, in whole or in part, to carry out its obligations
under this Agreement, with the exception of payment obligations under this Agreement, the obligations of such Party, to the extent that they are affected by such Force Majeure Event, shall be suspended during the continuance of such Force Majeure
Event provided that the Party prevented from performing by such Force Majeure Event:



| | (a) | provides the other Party with written notice of the occurrence of such Force Majeure Event within three days following the occurrence of such Force Majeure Event, which notice shall
describe such Force Majeure Event in reasonable detail and, to the extent practicable, include an estimate of the anticipated duration thereof;
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (b) | takes all actions reasonable necessary to remedy such Force Majeure Event or its resulting effects, or otherwise remove the basis for non-performance, as soon as practicable; and
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



- 26 -



---

| | (c) | upon such remedy or removal of the Force Majeure Event, resumes performance of its obligations under this Agreement.
| | --- | --------------------------------------------------------------------------------------------------------------------



|18. | DISPUTE RESOLUTION
|--- | ------------------



18.1. Amicable Settlement: All disputes arising out of or in connection with this Agreement or its performance, including without limitation the validity, scope, meaning, construction, interpretation or
application of this Agreement or any provision hereof shall be settled, to the extent reasonably practicable, by amicable negotiation, discussion and agreement between the Parties respective Chief Executive Officers, or their designees.



18.2. Inadmissibility: The parties agree that any discussions pursuant
to Subsection 18.1 are settlement negotiations and, to the extent allowed by Law, the subject matter of such discussions is not admissible in any future Proceedings. The parties shall not subpoena or otherwise require any mediator to testify or
produce any records, notes or documents in any future Proceedings.



18.3.
Arbitration: Any dispute arising out of or in connection with this Agreement that the Parties have not resolved in accordance with Subsection 18.1 shall be, at the election of Terra or Methanex, submitted to arbitration in accordance with the
following terms and procedures:



| | (a) | The Party seeking arbitration shall notify the American Arbitration Association (the AAA) and the other Party in writing describing in reasonable detail the
nature of the dispute (the Dispute Notice). The resolution of such dispute shall be determined by a panel of three arbitrators (the Arbitration Panel); one to be appointed by Methanex, one to be appointed by
Terra and a neutral arbitrator to be appointed by the arbitrators appointed by Methanex and Terra. The neutral arbitrator shall be an attorney and shall act as chairman. If either Party fails to appoint an arbitrator within 15 Business Days after
the dispute is submitted to arbitration, or the two arbitrators appointed by or on behalf of each Party fail to appoint a neutral arbitrator within 15 Business Days after the date of the appointment of the last arbitrator appointed by or on behalf
of each Party, then, the third arbitrator shall be appointed under the provisions of the Commercial Arbitration Rules of the AAA. Each Party appointed arbitrator shall have knowledge of or experience in the chemical industry. In the event that any
arbitrator is unable to serve, his or her replacement shall be selected in the same manner as the arbitrator to be replaced. The vote of two of the three arbitrators shall be required for any decision under this Subsection 18.3. The arbitration
shall be conducted in New York City or such other location that the Parties may mutually agree in writing;
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (b) | The arbitration shall be subject to the Federal Arbitration Act as supplemented by the conditions set forth in this Subsection 18.3. The arbitration shall be administered by the AAA
and shall be governed by the AAA Commercial Arbitration Rules, other than as specifically modified herein;
| | --- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (c) | The decision of, and award rendered by, the Arbitration Panel shall be in writing and shall be final and binding on each Party. The award of the Arbitration Panel shall be reasoned
and shall include written findings of fact and conclusions of Law. The fees and expenses of the Party appointed arbitrators shall be paid by the Party appointing such arbitrator and the fees and expenses of the neutral arbitrator shall be shared
equally by Methanex and Terra, provided, however, the Arbitration Panel may assess such fees and expenses in the manner it deems appropriate in connection with its decision;
| | --- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



- 27 -



---

| | (d) | During the arbitration of the dispute, each Party shall make available to the Arbitration Panel and to the other Party all books, records and other information within its control as
reasonably requested by the other Party or requested by the Arbitration Panel subject to the confidentiality provisions contained herein, and provided that no such access shall waive or preclude any objection to such production based on any
privilege recognized by Law. Recognizing the express desire of each Party for an expeditious means of dispute resolution, the Arbitration Panel may limit the scope of discovery between each Party as may be reasonable under the circumstances;
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (e) | In deciding the substance of each Partys Claims, the Laws of the State of New York shall govern the construction, interpretation and effect of this Agreement (including this
Subsection 18.3) without giving effect to any conflict of law principles;
| | --- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (f) | The arbitration hearing shall be commenced promptly and conducted expeditiously, with each Party involved in the dispute being allocated an equal amount of time for the presentation
of its case. Unless otherwise agreed to by each Party or ordered by the Arbitration Panel, the arbitration hearing shall be conducted on consecutive days. Time is of the essence in the arbitration Proceedings, and the Arbitration Panel shall have
the right and authority to issue monetary sanctions against any Party if, upon a showing of good cause, that Party is unreasonably delaying the Proceedings. To the fullest extent permitted by Law, the arbitration Proceedings and award shall be
maintained in confidence by the Arbitration Panel and each Party; and
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (g) | The Arbitration Panel shall decide all disputes and all substantive and procedural issues related thereto, and shall enforce this Agreement in accordance with its terms. Without
limiting the generality of the previous sentence, the Arbitration Panel shall have the authority to issue injunctive relief; however, the Arbitration Panel shall not have any power or authority to: (i) award consequential, indirect or incidental
damages (other than in Subsection 18.3(f) above), or punitive damages; or (ii) amend this Agreement. The Arbitration Panel shall render the arbitration award in writing following the completion of the arbitration hearing, setting forth the reasons
for the award. In the event that the Arbitration Panel awards monetary damages in favour of either Party, the Arbitration Panel must certify in the award that no consequential, indirect or incidental damages (except as specifically set forth under
the terms of this Agreement), punitive damages are included in such award. If the Arbitration Panels decision results in a monetary award, interest to be granted such award, if any, and the rate of such interest shall be determined by the
Arbitration Panel in their discretion. The arbitration award shall be final and binding on each Party, and judgment thereon may be entered in any court of competent jurisdiction, and may not be appealed except to the extent permitted by the Federal
Arbitration Act.
| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



18.4. Interim Relief: Each Party may, by
summary proceedings (e.g., a plea in abatement or motion to stay further proceedings), bring any action in any court of competent jurisdiction to (i) compel arbitration of any dispute; (ii) obtain interim measures of protection pending
arbitration of any dispute, to preserve the status quo pending resolution of the dispute, to prevent the destruction of documents and other information or things related to the dispute or to prevent the transfer, dissipation or hiding of
Assets; or (iii) enforce any decision of the Arbitration Panel, including the final award. The bringing of any such action shall not be deemed incompatible with the provisions of this Section 18 or a waiver of a Partys right to arbitrate.
Either Party who fails or refuses to submit to binding arbitration following a lawful demand by the other Party shall bear all costs and expenses incurred by such other Party in compelling arbitration of such dispute.

at all times during which any disputes are the subject of the dispute resolution procedures of this Section 18.

PRODUCT DELIVERY TERMS



1. Production Volumes: Prior to the first day of each calendar quarter, Terra will deliver to Methanex written notice of its minimum and maximum methanol
production volume (Min/Max Range) at the Beaumont Facility for the next calendar quarter on the basis of US Gallons/day. The Parties do not expect that minimum methanol production volumes shall be less than 630,000 Gallons/day nor
shall maximum methanol production volumes be greater than 660,000 Gallons/day. Methanex will use its reasonable efforts to nominate Product (as set forth in Section 3 below) within the minimum and maximum volume range set forth in this Section.



2. Forecasting: Prior to the first day of each month preceding a
calendar quarter Methanex shall provide to Terra a rolling forecast of Product expected to be required by Methanex in each of the next four quarters (Quarterly Forecast). For the avoidance of doubt, the Quarterly Forecast does not
constitute a commitment by Methanex to purchase such Product set forth in the Quarterly Forecast.



3. Product Nomination: In addition to the Quarterly Forecast required under Section 2 above, on or before the 15th day of each month Methanex shall provide to Terra a rolling three month forecast of its Product
requirements, the forecast for the first month of which shall constitute a firm commitment of Methanex to take delivery of and pay for such Product for that month.



4. Supply Limitations: Terra shall notify Methanex, within two days, of any and all potential supply limitations to minimize any
impact on Methanexs business as soon as practical after Terra becomes aware of such event or circumstance that may result in any potential supply limitations. Except with respect to a Force Majeure Event, Terra shall be liable for all costs
incurred by Methanex as a result of Terras failure to Deliver Product due to an Unscheduled Suspension including, without limitation, incremental costs incurred by Methanex to purchase, ship and store methanol to replace such Product not
Delivered (supporting documentation reasonably required by Terra), provided that the Unscheduled Suspension lasts longer than 15 days. If the Unscheduled Suspension is caused by the willful misconduct of Terra, or its officers, directors, employees
or contractors, then Terra shall be liable for all costs, as set forth in this Section 4, incurred by Methanex as a result of Terras failure to Deliver Product due to an Unscheduled Suspension, notwithstanding the duration of such Unscheduled
Suspension and commencing immediately upon the commencement of such Unscheduled Suspension.



5. Delivery of Methanol/Shipping Instructions: At least five Business Days prior to the first day of each month, Methanex shall provide written notice to Terra setting forth its requested dates, volumes of
deliveries and shipping requirements for Product for the coming month (the Delivery, Shipment and Storage Instructions). Terra shall be entitled to rely on the Delivery, Shipment and Storage Instructions unless the Parties agree
otherwise in writing. Terra shall use reasonable commercial efforts to comply with the Delivery, Shipment and Storage Instructions. Methanex may also deliver to Terra from time to time additional shipping instructions for Product and Terra shall use
reasonable commercial efforts to Deliver Product at the times specified in such instructions. All such additional shipping instructions shall be given as early as is practicable prior to the requested shipment date. Upon arranging each shipment of
Product, Terra shall provide Methanex with written notice of the particulars of such shipment.



6. Access to the Facility: Terra shall ensure that Methanex and its representatives shall be afforded access to the Beaumont Facility at reasonable times, seven days a week, as required by Methanex in
connection with the performance of its obligations under this Agreement, in particular, in order to take Delivery of Product under this Agreement. Terra shall make available to Methanex such of Terras

personnel as may be required by Methanex to access the Beaumont Facility under this Section 6, at no cost to Methanex.



7. Title and Risk of Loss: The title to the Product shall at all times remain with
Methanex. The risk of loss in the Product while the Product is being manufactured and stored at the Beaumont Facility and while passing through the pipelines shall remain with Terra at all times until it is Delivered to the designated party. For
greater certainty, the risk of loss shall transfer from Terra to the Pipeline Customers (on a Pipeline Customer by Pipeline Customer basis) as provided for in each Pipeline Customer Contracts.



8. Product Testing: Confirmatory tests of the quality of the Inventory and each
Product shipment from Terra to Methanex shall be performed (prior to delivery of such Product to Methanex) by or in the presence of an independent surveyor acceptable to the Parties, the cost and expense of which shall be borne by Methanex. Quality
of each such shipment of Product shall be tested by taking one representative sample from the storage tanks where the Product is stored by Terra, and from the tanks thereof where necessary, onto which such Product is loaded. Terra shall retain such
samples for not less than 90 days and shall provide Methanex with access to such samples and all records maintained by Terra with respect thereto. If a Claim regarding the quality of any given shipment is not raised by Methanex within 90 days of a
sample being taken by the independent surveyor, then Terra shall be entitled to dispose of the sample. If a Claim regarding the quality of any given shipment is raised by Methanex then Terra shall retain such sample that is the subject matter of the
Claim until the Claim has been finally settled. As between Terra and Methanex, all Product delivered to Methanex pursuant to this Agreement shall be conclusively presumed to be in compliance with the Specifications if, when tested in accordance with
the procedures set forth in this Section 8, analysis shows that such Product met the Specifications.



9. Defective Product: All Claims and Proceedings by Methanex respecting Defective Product shall be deemed waived unless made in writing and received by Terra within 60 days after receipt of the Product in
respect of which such claim is made or 60 days after Methanex discovers the existence of such Claim. Failure of Methanex to provide Terra with written notice of any such claim within the applicable time period shall be deemed an absolute and
unconditional waiver by Methanex of such claim.



10. Remedy for Defective
Product: Methanexs remedy with respect to any Product that is Defective Product, shall be a refund of the pro rata portion of the aggregate amount paid by Methanex pursuant to this Agreement during the month in which such Defective Product
was produced, such pro rata portion to be the percentage determined by dividing the amount of Product which is Defective Product by the aggregate amount of Product produced during such month. Methanex, in its sole option, may elect the remedy set
forth in this Section 10 by providing written notice to Terra.

DISCLOSURE SCHEDULE



The refractory lining system of the south reformer #1 transfer line exchanger (TLX) has been breached and a hotspot has occurred. Terra reported this to Methanex on
November 20th, 2003. Terra is monitoring the situation weekly and it is currently controlled. The situation could worsen at any time and force an unplanned outage but it is conceivable that it may not warrant a planned outage over the next six
months. If maintenance is necessary it will require 5 to 7 days excluding normal shutdown and start-up.
