        % Senior Notes due             

The US$            aggregate principal amount of        % Senior Notes due            (the “Notes”) offered by this prospectus supplement will bear interest at the rate of        % per annum from            , 2020 and will mature on            ,            . We will pay interest on the Notes on            and            of each year, beginning on            ,            . The Notes will be unsecured obligations and will rank equally with all of our other unsecured and unsubordinated obligations. We may redeem the Notes, in whole or in part, at any time at the redemption prices described in this prospectus supplement, including accrued and unpaid interest.

This prospectus supplement does not qualify the distribution of any Notes which may be offered or sold in any province or territory of Canada, including the Province of British Columbia, and any such sales will only be made pursuant to private placement exemptions from the prospectus requirements of the securities laws of such provinces and territories.

We will not apply to list the Notes on any securities exchange or to include the Notes in any automated quotation system. Accordingly, there is no market through which the Notes may be sold and purchasers may not be able to resell Notes purchased under this prospectus supplement. This may affect the pricing of the Notes in the secondary market, the transparency and availability of trading prices, the liquidity of the Notes and the extent of issuer regulation. See “Risk Factors”.

Investing in the Notes involves risks. See “Risk Factors” beginning on page S-17 of this prospectus supplement and on page 5 of the accompanying Short Form Base Shelf Prospectus dated August 22, 2019, as amended by Amendment No. 1 dated September 9, 2020 (referred to as the “accompanying prospectus” in this prospectus supplement).

None of the U.S. Securities and Exchange Commission (the “SEC”), the British Columbia Securities Commission (the “BCSC”) or any state, provincial or territorial securities commission has approved or disapproved of these securities or determined if this prospectus supplement or the accompanying prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

We are permitted, under a multijurisdictional disclosure system adopted by the United States and Canada, to prepare this prospectus supplement and the accompanying prospectus in accordance with Canadian disclosure requirements, which are different from U.S. disclosure requirements. Our financial statements, which are incorporated by reference herein, have been prepared, for all periods presented, in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board (“IFRS”). As a result, they may not be comparable to financial statements of U.S. companies.

Owning the Notes may subject you to tax consequences both in the United States and Canada. This prospectus supplement may not describe these tax consequences fully. You should read the tax discussion under “Material Income Tax Considerations” and are urged to consult with your own tax advisor with respect to your own particular circumstances.

Your ability to enforce civil liabilities under U.S. federal securities laws may be affected adversely by the fact that we are incorporated in Canada, most of our officers and directors and the experts named in this prospectus supplement and the accompanying prospectus are not residents of the United States, and many of our assets and all or a substantial portion of the assets of such persons are located outside of the United States.

Our earnings coverage ratio for the twelve month period ended June 30, 2020 is less than one-to-one. See “Pro Forma Earnings Coverage”.

Affiliates of certain of the underwriters are lenders to us under our credit facilities and to certain of our subsidiaries under certain debt obligations. Consequently, we may be considered to be a connected issuer of such underwriters under applicable Canadian securities legislation. See “Underwriting”.

We expect that delivery of the Notes will be made to investors in book-entry form through the facilities of The Depository Trust Company and its direct and indirect participants, including Euroclear Bank SA/NV, an operator of the Euroclear system, and Clearstream Banking, S.A., on or about             , 2020.

CAUTION REGARDING FORWARD-LOOKING STATEMENTS

This prospectus supplement and the accompanying prospectus, including the documents incorporated by reference herein and therein, contain certain forward-looking information and forward-looking statements, as defined in applicable securities laws (collectively referred to as “forward-looking statements”). These statements relate to future events or our future performance. All statements other than statements of historical fact are forward-looking statements. The use of any of (or variations of any of) the words “anticipate”, “plan”, “continue”, “estimate”, “expect”, “may”, “will”, “project”, “predict”, “potential”, “should”, “believe”, “target”, “plan”, “predict”, “aim”, “goal” and similar expressions are intended to identify forward-looking statements. Disclosure relating to the completion of the offering of Notes and the anticipated use of proceeds therefrom are also forward-looking statements. Forward-looking statements involve known and unknown risks, uncertainties and other factors which may cause actual results or events to differ materially from those implied by such forward-looking statements. These statements speak only as of the date of this prospectus supplement, the date of the accompanying prospectus or the date specified in the documents incorporated by reference in this prospectus supplement or the accompanying prospectus, as the case may be.

More particularly and without limitation, any statements regarding the following are forward-looking statements:

• expected demand for methanol and its derivatives;

• expected new methanol supply or restart of idled capacity and timing for start-up of the same;

• expected shutdowns (either temporary or permanent) or restarts of existing methanol supply (including our own facilities), including, without limitation, the timing and length of planned maintenance outages;

• expected methanol and energy prices;

• expected levels of methanol purchases from traders or other third parties;

• expected levels, timing and availability of economically priced natural gas supply to each of our plants;

• capital committed by third parties towards future natural gas exploration and development in the vicinity of our plants;

• our expected capital expenditures;

• anticipated operating rates of our plants;

• expected operating costs, including natural gas feedstock costs and logistics costs;

• expected tax rates or resolutions to tax disputes;

S-5

• expected cash flows, earnings capability and share price;

• availability of committed credit facilities and other financing;

• our ability to meet covenants associated with our long-term debt obligations, including, without limitation, the Egypt limited recourse debt facilities that have conditions associated with the payment of cash or other distributions;

• our shareholder distribution strategy and anticipated distributions to shareholders;

• commercial viability and timing of, or our ability to execute, future projects, plant restarts, capacity expansions, plant relocations, or other business initiatives or opportunities, including our Geismar 3 Project;

• expected outcomes of litigation or other disputes, claims and assessments;

• expected actions of governments, governmental agencies, gas suppliers, courts, tribunals or other third parties; and

• the potential future impact of the COVID-19 pandemic.

We believe that we have a reasonable basis for making such forward-looking statements. The forward-looking statements in this prospectus supplement and the accompanying prospectus, including documents incorporated by reference herein and therein, are based on our experience, our perception of trends, current conditions and expected future developments as well as other factors. Certain material factors or assumptions were applied in drawing the conclusions or making the forecasts or projections that are included in these forward-looking statements, including, without limitation, future expectations and assumptions concerning the following:

• the supply of, demand for, and price of methanol, methanol derivatives, natural gas, coal, oil and oil derivatives;

• our ability to procure natural gas feedstock on commercially acceptable terms;

• operating rates of our facilities;

• receipt or issuance of third-party consents or approvals or governmental approvals related to rights to purchase natural gas;

• the establishment of new fuel standards;

• operating costs, including natural gas feedstock and logistics costs, capital costs, tax rates, cash flows, foreign exchange rates and interest rates;

• the availability of committed credit facilities and other financing;

• global and regional economic activity (including industrial production levels);

• absence of a material negative impact from major natural disasters;

• absence of a material negative impact from changes in laws or regulations;

• absence of a material negative impact from political instability in the countries in which we operate; and

• enforcement of contractual arrangements and ability to perform contractual obligations by customers, natural gas and other suppliers and other third parties.

S-6

However, forward-looking statements, by their nature, involve risks and uncertainties that could cause actual results to differ materially from those contemplated by the forward-looking statements. The risks and uncertainties primarily include those attendant with producing and marketing methanol and successfully carrying out major capital expenditure projects in various jurisdictions, including, without limitation:

• conditions in the methanol and other industries including fluctuations in the supply, demand and price for methanol and its derivatives, including demand for methanol for energy uses;

• the price of natural gas, coal, oil and oil derivatives;

• our ability to obtain natural gas feedstock on commercially acceptable terms to underpin current operations and future production growth opportunities;

• the ability to carry out corporate initiatives and strategies;

• actions of competitors, suppliers, and financial institutions;

• conditions within the natural gas delivery systems that may prevent delivery of our natural gas supply requirements;

• the commercial viability of the Geismar 3 Project and our ability to meet timeline and budget targets for the Geismar 3 Project, including the impact of any cost pressures arising from labour costs;

• competing demand for natural gas, especially with respect to any domestic needs for gas and electricity;

• actions of governments and governmental authorities, including, without limitation, implementation of policies or other measures that could impact the supply of or demand for methanol or its derivatives;

• changes in laws or regulations;

• import or export restrictions, anti-dumping measures, increases in duties, taxes and government royalties, and other actions by governments that may adversely affect our operations or existing contractual arrangements;

• worldwide economic conditions;

• the impacts of the COVID-19 pandemic; and

• other risks described in the documents incorporated by reference in this prospectus supplement and the accompanying prospectus, including, without limitation, under the heading “Risk Factors and Risk Management” in our Annual MD&A.

We caution you that the foregoing list of important factors and assumptions is not exhaustive. Events or circumstances could cause our actual results to differ materially from those estimated or projected and expressed in, or implied by, these forward-looking statements.

You are cautioned not to place undue reliance on forward-looking statements. They are not a substitute for the exercise of one’s own due diligence and judgment. The outcomes implied by forward-looking statements may not occur and we do not undertake to update forward-looking statements except as required by applicable securities laws. You should also carefully consider the matters discussed under “Risk Factors” beginning on page S-17 of this prospectus supplement and on page 5 of the accompanying prospectus.

SUMMARY

The following section summarizes more detailed information presented later in this prospectus supplement, in the accompanying prospectus or in the documents incorporated by reference herein and therein. You should read the entire prospectus including, in particular, the “Risk Factors” beginning on page S-17 of this prospectus supplement and on page 5 of the accompanying prospectus, as well as the documents incorporated by reference herein and therein, including our consolidated financial statements and the related management’s discussion and analysis.

Our Company

Overview

We are the world’s largest producer and supplier of methanol to major international markets in Asia Pacific, North America, Europe and South America. Our total annual operating capacity, including Methanex interests in jointly owned plants, in New Zealand, the United States, Trinidad, Chile, Egypt and Canada, is currently 9.2 million tonnes. In addition to the methanol produced at our sites, we purchase methanol produced by others under methanol offtake contracts and on the spot market. This gives us flexibility in managing our supply chain while continuing to meet customer needs and support our marketing efforts. We have marketing rights for 100% of the production from our jointly-owned plants in Trinidad and Egypt, which provides us with an additional 1.3 million tonnes per year of methanol offtake supply when the plants are operating at full capacity.

In the first half of 2020, we have seen lower methanol demand due to the impact from the COVID-19 pandemic and lower oil price environment. In response, we have idled two methanol plants for an indefinite period, drawn on our credit facilities, reduced our quarterly dividend, deferred approximately $500 million of capital spending on the Geismar 3 Project, reduced maintenance capital and operating costs, and secured additional financial flexibility by negotiating meaningful financial covenant relief on our credit facilities. Our manufacturing sites are operating safely with strict controls in place to monitor employee health and minimize staff onsite in locations where the risks of COVID-19 continue to be high. Our global supply chain continues to run effectively. We have begun to see some signs of improving methanol demand as easing of government restrictions have resulted in higher industrial production levels and fuel demand has increased as oil prices have stabilized.

The following table sets forth certain operating data and other information for our methanol operations at each of our existing facilities:

(Thousands of tonnes)	Annual Operating Capacity(1)		2018 Production		2019 Production		YTD Q2 2020 Production
New Zealand(2)		2,200		1,606		1,865		893
Geismar (USA)		2,000		2,078		1,929		971
Trinidad (Methanex interest)(3)		2,000		1,702		1,743		670
Chile(4)		1,720		612		1,050		523
Egypt (50% interest)		630		613		392		280
Medicine Hat (Canada)		600		600		610		298
		9,150		7,211		7,589		3,635

(1) Annual operating capacity reflects, among other things, average expected plant outages, turnarounds and average age of the facility’s catalyst. The operating capacity of our production facilities may be higher or lower than original nameplate capacity as, over time, these figures have been adjusted to reflect ongoing operating efficiencies at these facilities and expected feedstock composition. Actual production for a facility

S-8

in any given year may be higher or lower than operating capacity due to a number of factors, including natural gas composition or the age of the facility’s catalyst.

(2) The operating capacity of New Zealand is made up of the two Motunui facilities and the Waitara Valley facility. The New Zealand facilities are capable of producing up to 2.4 million tonnes annually, depending on natural gas composition and availability. Based on the current outlook for available high CO2 natural gas, we expect the New Zealand annual operating capacity to be approximately 2.2 million tonnes.

(3) The operating capacity of Trinidad is made up of the Titan (100% interest) and Atlas (63.1% interest) facilities. On March 16, 2020, we announced that we had idled our Titan plant effective on that date for an indefinite period in response to the impact of the COVID-19 pandemic on global methanol demand. Since idling, the Titan plant gas supply agreement has expired and we are currently negotiating with the National Gas Corporation of Trinidad and Tobago for a new gas supply agreement.

(4) The operating capacity of our Chile I and Chile IV facilities is 1.7 million tonnes annually assuming access to natural gas feedstock. For 2018, our operating capacity in Chile was 0.9 million tonnes. In the fourth quarter of 2018, we restarted our 0.8 million tonne Chile IV plant that had been idle since 2007. On March 16, 2020, we announced that we would idle our Chile IV plant effective on April 1, 2020 for an indefinite period in response to the impact of the COVID-19 pandemic on global methanol demand.

In New Zealand, we produced 1.9 million tonnes of methanol in 2019 compared to 1.6 million tonnes in 2018 and produced 0.9 million tonnes in both the first half of 2020 and the same period in 2019. Production for 2019 was higher than 2018 due to planned turnarounds and maintenance activities at both the Motunui and Waitara Valley sites in 2018 and more significant gas supply constraints due to planned and unplanned gas field and pipeline maintenance and repairs in 2018 as compared to 2019. Field development work is underway in the upstream gas sector in New Zealand; however, we do not expect to see the benefit of this in 2020.

The Geismar facilities, Geismar 1 and 2, produced 1.9 million tonnes of methanol in 2019 compared to 2.1 million tonnes in 2018 and produced 1.0 million tonnes in the first half of 2020 compared to 0.9 million tonnes during the same period in 2019. Production at the Geismar site was lower for 2019 compared with 2018 due primarily to a planned turnaround at Geismar 1 in the first quarter of 2019 and unplanned outages at Geismar 2 in the fourth quarter of 2019. Production was higher in the first half of 2020 compared to the same period in 2019 due to planned maintenance activities undertaken in 2019.

Our ownership interest in the methanol facilities in Trinidad represents 2.0 million tonnes of annual capacity. The Trinidad facilities produced a total of 1.7 million tonnes of methanol (Methanex share) in both 2019 and 2018 and produced 0.7 million tonnes in the first half of 2020 compared to 0.8 million tonnes during the same period in 2019. Production in Trinidad was similar in 2019 and 2018 as a turnaround completed at the Titan plant in 2019 offset the impact of fewer unplanned outages in 2019 compared to 2018. Production was lower in the first half of 2020 compared to the same period in 2019 due to the Titan plant being idled effective March 16, 2020 in response to the impact of the COVID-19 pandemic on global methanol demand.

The Chile facilities, Chile I and IV, produced 1.1 million tonnes of methanol in 2019 from a combination of Chile and Argentina sourced natural gas. This compares to 0.6 million tonnes in 2018. The Chile facilities produced 0.5 million tonnes in both the first half of 2020 and the same period in 2019. Production increased for 2019 as compared to 2018 as a result of improved natural gas availability from Chilean and Argentine suppliers that allowed the restart of our Chile IV plant that had been idle since 2007. Chile IV was idled effective April 1, 2020 in response to the impact of the COVID-19 pandemic on global methanol demand. We expect that our current gas agreements will allow for a two-plant operation in Chile during the southern hemisphere summer months and up to a maximum of 75% of a two-plant operation annually. The future of our Chile operations is primarily dependent on the level of natural gas exploration and development in southern Chile and our ability to secure a sustainable natural gas supply to our facilities on economic terms from Chile and Argentina. We are optimistic that we will be able to secure sufficient gas to underpin a full two-plant operation over the coming years.

S-9

We operate the 1.3 million tonne per year methanol facility in Egypt and have marketing rights for 100% of production from this facility. The Egypt methanol facility is well located to supply the domestic and European methanol markets, and can also supply Asia Pacific. We produced 0.8 million tonnes of methanol (Methanex share of 0.4 million) at the plant during 2019 compared to 1.2 million tonnes (Methanex share of 0.6 million) in 2018 and produced 0.6 million tonnes (Methanex share of 0.3 million tonnes) during the first half of 2020 compared to 0.3 million tonnes (Methanex share of 0.2 million tonnes) during the same period in 2019. Production for 2019 was lower compared to 2018 as the Egypt facility experienced an outage in April 2019 and remained off-line until August 2019 for inspections and repair work. The plant ran at full rates subsequent to restarting in August, 2019. Production for the first half of 2020 is also higher than the first half of 2019 due to the 2019 outage.

The Medicine Hat facility produced 610,000 tonnes of methanol in 2019 compared to 600,000 tonnes in 2018 and produced 298,000 tonnes in the first half of 2020 compared to 310,000 tonnes during the same period in 2019.

In July 2019, our board of directors approved the construction of the Geismar 3 Project, a 1.8 million tonne methanol plant adjacent to our existing Geismar 1 and Geismar 2 facilities. The cost of the Geismar 3 Project is expected to be between $1.3 and $1.4 billion, excluding capitalized interest. In April 2020, in light of the significant uncertainty in the global economy due to the COVID-19 pandemic, the Company placed the Geismar 3 Project on temporary care and maintenance and deferred approximately $500 million of previously announced capital spending for up to 18 months. As of June 30, 2020, we had invested $312 million in the Geismar 3 Project, excluding capitalized interest of $15 million. Over the 15 month period starting on July 1, 2020, we anticipate continuing to invest approximately $130 million in the Geismar 3 Project while it is on temporary care and maintenance. We have not yet made a decision on whether to restart the Geismar 3 Project. There are a number of factors that the Company and our board will consider carefully in connection with any decision to restart the Geismar 3 Project, including whether we have clear evidence of a global economic recovery and solid methanol demand outlook; a firm view that the methanol industry needs new capacity to meet demand growth; a robust methanol pricing forecast; an ability to fund the project; and confidence that our suppliers are able to complete construction and deliver materials and equipment on time and on budget in light of any COVID-19 restrictions.

Methanol is a clear liquid commodity chemical that is predominantly produced from natural gas and is also produced from coal, particularly in China. Traditional chemical demand, which represents just over 50% of global methanol demand, is used to produce traditional chemical derivatives, including formaldehyde, acetic acid and a variety of other chemicals that form the basis of a wide variety of industrial and consumer products. Demand for energy-related applications, which represents just under 50% of global methanol demand, includes a number of applications including methanol-to-olefins (“MTO”), methyl tertiary-butyl ether (“MTBE”), fuel applications (including vehicle fuel, marine fuel and as a fuel for industrial boilers and kilns), di-methyl ether (“DME”) and biodiesel.

Methanol is a global commodity and our earnings are significantly affected by fluctuations in the price of methanol, which is directly impacted by changes in methanol supply and demand. Based on the diversity of end products in which methanol is used, demand for methanol is driven by a number of factors including strength of global and regional economies, industrial production levels, energy prices, pricing of end products and government regulations and policies.

The near-term outlook for methanol demand is uncertain due to the impact of COVID-19 on manufacturing activity and low oil prices. Current methanol prices are at cyclical lows and estimated to be around the cash costs of the industry marginal producer. We believe the industry cost curve underpins prices and we expect rationalization of high-cost industry supply in a sustained low-price environment. There are some near-term

S-10

large-scale capacity additions that we expect to be completed, although timing is uncertain given COVID-19 restrictions, the state of the global economy and the low methanol price environment. However, we believe the medium-to-long-term outlook for methanol demand growth remains strong across traditional and energy-related applications and industry capacity additions will be needed to meet anticipated demand growth.

Demand

We estimate that global methanol demand totaled approximately 84 million tonnes in 2019, a 3% increase compared to 2018.

Traditional chemical demand, which represents just over 50% of global demand, was flat in 2019 compared to 2018 as a result of slower global economic growth, particularly in the automotive and construction markets, and various planned and unplanned downstream outages. We believe that traditional chemical demand is influenced by the strength of global and regional economies and industrial production levels.

Demand for energy-related applications, which represents just under 50% of global demand, was robust and grew 7% in 2019, supported by the start-up of two new MTO plants. The future operating rates and methanol consumption from MTO producers will depend on a number of factors, including pricing for their various final products, the degree of downstream integration of these units with other products, the impact of olefin industry feedstock costs, including naphtha, on relative competitiveness and plant maintenance schedules.

Regulatory changes are playing an increasing role in encouraging new applications for methanol due to its emissions benefits as a fuel.

The International Maritime Organization (“IMO”) implemented a new regulation in 2020, limiting sulphur emissions from ocean-going vessels. Methanol has emerged as a promising competitive alternative marine fuel that meets the IMO’s sulphur requirements. Methanex currently has 11 vessels with the capacity to run on methanol. A number of projects have been completed or are underway with cruise ships and ferries as well as tug boats and barges. In China, Methanex has partnered with the Ministry of Transport on a successful marine fuel pilot and is working with relevant stakeholders to support the application of methanol as a marine fuel.

There is growing interest in methanol as a vehicle fuel. In 2019, a number of Chinese government ministries published “Guidelines to Promote Methanol Vehicles in China” to expedite the development of methanol fueled vehicles, including a pilot program for M100 taxis able to run on 100% methanol fuel. There are approximately 19,000 M100 taxis in China, representing approximately 400,000 tonnes of annual methanol demand. Additionally, methanol fuel blending continues to gain momentum outside of China, with several other countries in the assessment or near-commercial stage for low-level methanol fuel blending.

In China, stricter air quality emissions regulations in several provinces are leading to a phase-out of coal-fueled industrial boilers and industrial kilns in favour of cleaner fuels, creating a growing market for methanol as an alternative fuel. We estimate that this growing demand segment already represents approximately two million tonnes of methanol demand.

We believe that demand for energy-related applications is influenced by energy prices, pricing of end products and government regulations and policies.

We estimate that global methanol demand declined by approximately 3% in the first half of 2020 compared to the first half of 2019 due to the impact of the COVID-19 pandemic and lower energy price environment, which were partially offset by new MTO demand that started up in the second half of 2019. By mid-2020, we began to see some early signs of improving methanol demand with global economic activity beginning to recover and with oil pricing stabilizing. However, the near-term outlook remains uncertain as we believe that it is not possible to accurately predict the full extent and duration of the COVID-19 pandemic and lower oil price environment.

S-11

Supply

Outside of China, approximately four million tonnes of new annualized capacity, including existing capacity expansions, was introduced in 2019, including our 0.8 million tonne Chile IV methanol plant that restarted in late 2018, the 2.4 million tonne Kaveh methanol plant that started up in early 2019 in Iran, a 0.4 million tonne OCI plant in the Netherlands that restarted in the second half of 2019 and capacity expansions in the United States and Middle East. In China, we estimate that approximately three million tonnes of net new production capacity was added in 2019, excluding methanol production that is integrated with production of other downstream products and not sold on the merchant market.

As we previously announced, we idled our Titan plant in Trinidad (annual capacity of 875 thousand tonnes) effective March 16, 2020 and our Chile IV plant (annual capacity of 840 thousand tonnes) effective April 1, 2020 in response to the impact of the COVID-19 pandemic on global methanol demand. We have seen other producers in Trinidad, Argentina, the Netherlands, Russia and China reduce operating rates or shut down. We estimate that global methanol supply declined by approximately 9% in the second quarter of 2020 compared to the fourth quarter of 2019.

Over the next few years, the majority of large-scale capacity additions outside of China are expected to be in the Americas and the Middle East. Two plants were expected to be completed in 2020, including a 1.0 million tonne plant in Trinidad that began construction in 2016, being built by Caribbean Gas Chemical Limited, and a 1.7 million tonne plant in Louisiana that began construction in 2017, being built by Koch Methanol Investments and Yuhuang Chemical Industries. However, given the potential impact of the COVID-19 pandemic on construction and commissioning of these plants, the start-up timing of these plants is uncertain. There are other large-scale projects under discussion in North America; however, we believe that none have yet reached a final investment decision. We continue to monitor a number of projects at various stages of construction in Iran, including the Bushehr and Kimiya Pars plants, which we understand are running on an intermittent basis.

Methanol prices will ultimately depend on the strength of the global economy, industry operating rates, global energy prices, new supply additions and the strength of global demand. We believe that our resilient business model and strong liquidity, outstanding global supply network and competitive cost position will provide a sound basis for Methanex to continue to be the leader in the methanol industry.

Our Strategy and Competitive Strengths

Our primary objective is to create value through our leadership in the global production, marketing and delivery of methanol to customers. To achieve this objective we have a simple, clearly defined strategy: global leadership, low cost and operational excellence.

Global Leadership

Global leadership is a key element of our strategy. We are focused on creating value through our position as the major producer and supplier in the global methanol industry, improving our ability to cost-effectively deliver methanol to customers and supporting both traditional and energy-related global methanol demand growth.

We are the leading producer and supplier of methanol to the major international markets in Asia Pacific, North America, Europe and South America. Our 2019 sales volume of 11.1 million tonnes of methanol represented approximately 13% of global methanol demand. This scale allows us the flexibility to meet customer needs across international markets. Our leadership position has also enabled us to play an important role in the industry, which includes publishing Methanex reference prices that are used in each major market as the basis of pricing for our customer contracts.

S-12

The geographically diverse locations of our production sites allow us to deliver methanol cost-effectively to customers in all major global markets. We continue to invest in global distribution and supply infrastructure, which includes a fleet of ocean-going vessels and terminal capacity within all major international markets, which enables us to enhance value to customers by providing reliable and secure supply.

Low Cost

A low cost structure is an important competitive advantage in a commodity industry and is a key element of our strategy. Our approach to major business decisions is guided by a drive to improve our cost structure. The most significant components of total costs are natural gas for feedstock and distribution costs associated with delivering methanol to customers.

We manage our natural gas costs in two ways: through gas contracts linked to the methanol price and through fixed price contracts. Our production facilities outside of North America are largely underpinned by natural gas purchase agreements where the natural gas price is linked to methanol prices. This pricing relationship enables these facilities to be competitive throughout the methanol price cycle. In North America, we have fixed price contracts and hedges in place for our Geismar and Medicine Hat facilities with a higher portion of our gas requirements at fixed prices in the near-term, with the percentage at fixed prices declining as contracts within our portfolio expire through to 2032. In the near-term, we have approximately 70% of our gas requirement at fixed prices. We purchase our remaining North American gas requirements through the spot market. Our hedging strategy in North America manages natural gas price risk and its impact on our cost structure.

Our production facilities are well located to supply global methanol markets. Nevertheless, the cost to distribute methanol from production locations to customers remains a significant component of total operating costs. These include costs for ocean shipping, in-market storage facilities and in-market distribution. We continually focus on identifying initiatives to reduce these costs, including optimizing the use of our shipping fleet, third-party backhaul arrangements and taking advantage of prevailing conditions in the shipping market by varying the type and length of term of ocean vessel contracts. We also look for opportunities to leverage our global asset position by entering into geographic product exchanges with other methanol producers to reduce distribution and transportation costs.

Operational Excellence

We maintain a focus on operational excellence in all aspects of our business. This includes excellence in manufacturing and supply chain processes, marketing and sales, human resources, corporate governance practices and financial management.

To differentiate ourselves from competitors, we strive to be the best operator in all aspects of our business and to be the preferred supplier to customers. We believe that reliability of supply is critical to the success of our customers’ businesses and our goal is to deliver methanol reliably and cost-effectively.

Our strategy of operational excellence also includes the financial management of the Company. We operate in a highly competitive commodity industry. Accordingly, we believe it is important to maintain financial flexibility and we have adopted a prudent approach to financial management. As at June 30, 2020, we had a strong liquidity position with a cash balance of $783 million. In addition, we have no near-term debt maturities, and we have capacity to draw a further $100 million on our $300 million revolving credit facility and room to draw a further $627 million on our $800 million non-revolving construction facility for the construction of the Geismar 3 Project. Both facilities are provided by a syndicate of highly rated financial institutions and mature in July 2024. In the second quarter of 2020, we amended both facilities and obtained a related waiver from our lenders, providing us with meaningful financial covenant relief.

Risk Factors An investment in the Notes is subject to certain risks.

You should consider carefully all of the information set forth in this prospectus supplement and the accompanying prospectus and, in particular, you should evaluate the specific factors discussed in the section “Risk Factors”, beginning on page S-17 of this prospectus supplement and on page 5 of the accompanying prospectus, before deciding to invest in the Notes.

S-16

RISK FACTORS

An investment in the Notes involves risk. Before deciding whether to invest in the Notes, you should consider carefully the risks described below as well as the other information contained and incorporated by reference in this prospectus supplement, the accompanying prospectus and the documents incorporated by reference herein (including subsequent documents incorporated by reference herein). These are not the only risks and uncertainties that we face. In particular, please read “Risk Factors and Risk Management” in our Annual MD&A, “Risk Factors” in the accompanying prospectus, and “Caution Regarding Forward-Looking Statements” herein, where we describe additional risks and uncertainties associated with our business and the forward-looking statements contained in this prospectus supplement, the accompanying prospectus and the documents incorporated by reference herein. Additional risks not presently known to us or that we currently consider immaterial may also materially and adversely affect us. If any of the events identified in these risks and uncertainties were to actually occur, our business, financial condition or results of operations could be materially harmed.

COVID-19 is having, and may continue to have, a negative impact on our business, the magnitude of which is uncertain.

COVID-19 has negatively impacted our business and there is significant uncertainty with respect to the future impact of COVID-19 on our business. The magnitude of the impact will depend on future developments which cannot currently be predicted, including the speed at which manufacturing activity will return to prior levels, the impacts on supply chains, our ability to operate our facilities, and our ability to carry-out large-scale maintenance activities at our facilities as a result of labour shortages due to government imposed travel and assembly restrictions. We are actively assessing, and responding where possible, to the potential effects of the COVID-19 outbreak on our employees, customers, suppliers, and logistics providers, and evaluating the impact of governmental actions being taken to curtail its spread. We expect that our financial results for 2020 will be negatively impacted by the pandemic and we cannot currently estimate the overall severity or duration of any resulting adverse impact on our business, results of operations and financial condition. Finally, considering what has been experienced to date and further potential impacts, we cannot provide assurance that the deterioration in economic conditions will not have a material adverse impact on our results of operations and financial condition.

Our structure as a holding company could adversely affect our ability to meet our obligations under the Notes.

We are structured primarily as a holding company with limited material business operations, sources of income or assets of our own other than the shares of our subsidiaries. The Notes will be our obligations exclusively. Unless certain covenants in the Indenture become applicable, our subsidiaries will not guarantee the payment of principal or interest on the Notes and the Notes will therefore be structurally subordinated to the obligations of our subsidiaries as a result of our being structured as a holding company. In the event of insolvency, liquidation or other reorganization of any of our subsidiaries, our creditors (including the holders of the Notes) will not have any right to proceed against the assets of that subsidiary or to cause the liquidation or bankruptcy of such subsidiary under applicable bankruptcy laws. Creditors of such subsidiary would be entitled to payment in full from its assets before we would be entitled to receive any distribution from such assets. Except to the extent that we may ourselves be a creditor with recognized claims against a subsidiary, claims of creditors of that subsidiary will have priority with respect to the assets and earnings of that subsidiary over the claims of our creditors, including claims under the Notes. As of June 30, 2020, our subsidiaries and joint venture companies had approximately US$1,680 million of liabilities (which amount includes approximately US$465 million of trade payables, approximately US$735 million of leases, approximately US$265 million of other payables and accrued liabilities and approximately US$215 million of limited recourse debt which is secured by the assets of the Egypt entity or other limited recourse entities).

In addition, as a result of our holding company structure, our operating cash flow and our ability to service our debt, including the Notes, are dependent upon the operating cash flow of our subsidiaries and the payment of

S-17

funds by our subsidiaries to us in the form of dividends, loans or otherwise. Our subsidiaries are distinct legal entities and have no obligation, contingent or otherwise, to pay any amounts due under the Notes or to make any funds available therefor, whether by dividends, interest, loans, advances or other payments. In addition, the payment of dividends and the making of loans, advances and other payments to us by our subsidiaries may be subject to statutory or contractual restrictions, are contingent upon the earnings of our subsidiaries and joint venture companies and are subject to various business and other considerations.

The Notes will be effectively junior to our secured debt to the extent of the assets securing the same.

The Notes are unsecured obligations and will rank equally in right of payment with all of our other existing and future unsecured and unsubordinated obligations. The Notes are not secured by any of our assets. Claims of secured lenders with respect to assets securing their loans will be prior to any claim of the holders of the Notes with respect to those assets. Although our various debt instruments restrict secured indebtedness, a substantial amount of such indebtedness may still be incurred. As of June 30, 2020, we had approximately US$377 million of secured debt outstanding.

Our debt service requirements may affect our ability to fund our business.

As at June 30, 2020, without giving effect to the sale of the Notes, we had total indebtedness of approximately US$2,128 million (including 100% of Egypt and other limited recourse debt). After giving effect to the sale of the Notes and the application of the net proceeds as described in “Use of Proceeds”, we would have had total indebtedness of approximately US$             million. In addition, we have a committed revolving credit facility in the principal amount of US$300 million (of which $100 million is undrawn) that matures in July 2024 and a non-revolving construction facility for the Geismar 3 Project in the principal amount of US$800 million (of which US$627 million is undrawn and can only be used to finance a percentage of direct project expenditure) that also matures in July 2024. The Indenture and our credit facilities permit us and our subsidiaries to incur additional indebtedness, including secured indebtedness, subject to certain limitations. Our level of indebtedness could increase our vulnerability to general adverse economic and industry conditions, place us at a disadvantage compared to our competitors that have less debt, and limit our flexibility in planning for or reacting to changes in our business and industry, including as a result of the COVID-19 pandemic.

Our ability to make payments on and to refinance our indebtedness, including the Notes, and to fund our operations, working capital and capital expenditures will depend on our ability to generate cash in the future. This is subject to general economic, industry, financial, competitive, legislative, regulatory and other factors that are beyond our control. In particular, global or regional economic conditions could cause the price of methanol to fall and hamper our ability to make interest payments on or repay our indebtedness, including the Notes. We may need to refinance all or a portion of our indebtedness, including the Notes, on or before maturity. We cannot assure you that we will be able to refinance any of our indebtedness, including the Notes, on commercially acceptable terms, if at all.

Restrictions in our debt agreements may affect our ability to fund our business.

At June 30, 2020, our long-term debt obligations included US$1,550 million in unsecured notes (US$250 million that matures in 2022, US$300 million that matures in 2024, US$700 million that matures in 2029, and US$300 million that matures in 2044), approximately US$63 million related to the Egypt limited recourse debt facilities (representing 100% of the debt, including the 50% non-controlling interest share), US$200 million drawn on our committed revolving credit facility, US$173 million drawn on our non-revolving construction facility for the Geismar 3 project and approximately US$157 million of other limited recourse debt (100% basis) related to the financing of ocean going vessels which we own through less than wholly-owned entities. Our credit facilities are provided by highly rated financial institutions and mature in July 2024 and

S-18

contain customary covenant and default provisions. Significant covenants and default provisions under these facilities include:

• other than for the negotiated waiver period, for which certain financial covenant relief has been provided under the facilities as further described below, the obligation to maintain an EBITDA to interest coverage ratio of greater than or equal to 2:1 calculated on a four-quarter trailing average basis, where for only one quarter during the term of the credit facility the ratio can be as low as, but not less than 1.25:1, and a debt to capitalization ratio of less than or equal to 57.5%, both calculated in accordance with definitions in the credit agreement, which include adjustments related to limited recourse subsidiaries;

• a default if payment is accelerated by the creditor on any indebtedness of US$50 million or more of the Company and its subsidiaries, except for the limited recourse subsidiaries; and

• a default if a default that permits a creditor to demand repayment occurs on any other indebtedness of US$50 million or more of the Company and its subsidiaries, except for the limited recourse subsidiaries.

Our credit facilities also include customary covenants, including restrictions on the incurrence of additional indebtedness and restrictions on the sale or abandonment of the Geismar 3 Project, as well as requirements associated with completion of the Geismar 3 plant construction and commissioning. In addition, we are only able to draw up to 70% of our total costs on the Geismar 3 Project under our non-revolving construction facility. On June 3, 2020, we amended the terms of the revolving credit facility and the non-revolving construction facility for the Geismar 3 Project to modify and waive certain covenants, which included (i) increasing the debt to capitalization ratio such that the debt to capitalization ratio has to be less than or equal to 60% for each of the measurement periods starting on June 30, 2020 and ending on June 30, 2023 and (ii) lowering or waiving, as applicable, the minimum EBITDA to interest coverage ratio threshold for each of the measurement periods starting June 30, 2020 and ending on June 30, 2021.

The Egypt and other limited recourse debt facilities are described as limited recourse as they are secured only by the assets of the Egypt entity and other limited recourse entities, respectively. Accordingly, the lenders to the limited recourse debt facilities have no recourse to us or our other subsidiaries. The Egypt limited recourse debt facilities have covenants and default provisions that apply only to the Egypt entity, including restrictions on the incurrence of additional indebtedness and a requirement to fulfill certain conditions before the payment of cash or other distributions.

We cannot provide assurance that we will be able to access new financing in the future on commercially acceptable terms or at all, or that the financial institutions providing the credit facilities will have the ability to honour future draws. Additionally, failure to comply with any of the covenants or default provisions of the long-term debt facilities described above could result in a default under the applicable credit agreement that would allow the lenders to not fund future loan requests, accelerate the due date of the principal and accrued interest on any outstanding loans or restrict the payment of cash or other distributions. Any of these factors could have a significant negative effect on our results of operations, our ability to pursue and complete strategic initiatives or on our financial condition.

Restrictions in our debt agreements could limit our growth and our ability to respond to changing conditions.

Our senior credit facilities and the Indenture contain a number of significant covenants, which may limit our ability, among other things, to:

• merge or enter into certain other business combination transactions;

• create certain liens on our assets to secure debt;

• enter into sale and leaseback transactions; and

• incur additional debt.

S-19

In addition, our senior credit facilities require us to maintain certain financial ratios and satisfy certain financial condition tests and may require us to take action to reduce our debt or take some other action should we not satisfy these financial ratios or tests.

These restrictions could limit our ability to obtain future financing, make needed capital expenditures, withstand a future downturn in our business or the economy in general, or otherwise conduct necessary corporate activities. We may also be prevented from taking advantage of business opportunities that arise because of the limitations that the restrictive covenants under our senior credit facility and the Indenture impose on us.

A breach of any of these covenants could result in a default under the applicable debt agreement. A default, if not waived, could result in acceleration of the debt outstanding under the agreement and in a default with respect to, and acceleration of, the debt outstanding under other debt agreements. The accelerated debt would become immediately due and payable. If that should occur, we may not be able to pay all such debt, including the Notes.

We may be unable to repay the Notes when due or repurchase the Notes when we are required to do so.

At final maturity of the Notes or in the event of acceleration of the Notes following an event of default, the entire outstanding principal amount of the Notes will become due and payable. If we were unable to make the required payments or repurchases of the Notes, it would constitute an event of default under the Notes and, as a result, under our credit facilities and certain other outstanding indebtedness. See “Description of Debt Securities — Events of Default” in the accompanying prospectus. It is possible that we will not have sufficient funds at maturity or upon acceleration to make the required payments or repurchases of Notes and other debt securities.

We may not be able to finance an offer to purchase the Notes and other indebtedness upon the occurrence of a Change of Control Triggering Event.

Upon the occurrence of a Change of Control Triggering Event, as defined in the Indenture, we will be required to offer to purchase all outstanding Notes at a price in cash equal to 101% of the aggregate principal amount of the Notes, plus accrued and unpaid interest thereon. See “Description of Debt Securities — Certain Covenants — Change of Control” in the accompanying prospectus. It is possible that we will not have or will not be able to obtain on commercially reasonable terms, or at all, sufficient funds at such time to make the required purchase of the Notes.

Holders may not be able to require us to purchase their Notes in certain circumstances involving a significant change in the composition of our board of directors, including a proxy contest where our board of directors does not endorse the dissident slate of directors but approves them as Continuing Directors (as defined in the Indenture). In this regard, a decision of the Delaware Chancery Court (not involving us or our securities) considered a change of control redemption provision of an indenture governing publicly traded debt securities that is substantially similar to the change of control event described in clause (4) of the definition of “Change of Control.” In its decision, the court noted that a board of directors may “approve” a dissident shareholder’s nominees solely for purposes of such an indenture, provided the board of directors determines in good faith that the election of the dissident nominees would not be materially adverse to the interests of the corporation or its stockholders (without taking into consideration the interests of the holders of debt securities in making this determination).

It may be difficult for you to enforce liabilities against us based solely upon the federal securities laws of the United States.

We are organized under the laws of Canada and our principal executive office is located in Vancouver, British Columbia. Most of our officers and directors and the experts named in this prospectus supplement and the accompanying prospectus are not residents of the United States, and many of our assets and all or a substantial

S-20

portion of the assets of such persons are located outside of the United States. As a result, it may be difficult for you to effect service of process within the United States upon such directors, officers and experts, or to enforce against them judgments of U.S. courts based upon civil liability under the federal securities laws of the United States. There is doubt as to the enforceability in Canada of judgments against us or against any of our directors, officers or experts, in original actions or in actions for enforcement of judgments of U.S. courts, based solely upon the federal securities laws of the United States.

There is currently no active trading market for the Notes. If an active trading market does not develop for the Notes, you may not be able to resell them.

No active trading market currently exists for the Notes and none may develop. We do not intend to apply for the listing of the Notes on any securities exchange or quotation system. As a result, an active trading market may not develop for the Notes. If an active trading market for the Notes does not develop, it could have an adverse effect on the market price and your ability to resell the Notes.

Credit rating downgrades could adversely affect the trading price of the Notes.

The trading price for the Notes may be affected by our credit rating. Credit ratings are continually revised. Any downgrade in our credit rating could adversely affect the trading price of the Notes or the trading markets for the Notes to the extent trading markets for the Notes develop.

A financial failure by any entity in which we have an interest may hinder the payment of the Notes.

A financial failure by any entity in which we have an interest could affect payment of the Notes if a bankruptcy court were to “substantively consolidate” that entity with our subsidiaries and/or with us. If a bankruptcy court substantively consolidated an entity in which we have an interest with our subsidiaries and/or with us, the assets of each entity so consolidated would be subject to the claims of creditors of all entities so consolidated. This could expose our creditors, including holders of the Notes, to potential dilution of the amount ultimately recoverable because of the larger creditor base.

S-21

USE OF PROCEEDS

We estimate the net proceeds from the sale of the Notes, after deducting estimated underwriting commissions and expenses, will be approximately US$            million. We intend to use the net proceeds from the sale of the Notes (i) to repay or redeem our existing 5.25% unsecured notes due March 1, 2022, of which US$250 million in aggregate principal amount is outstanding, and (ii) for maintenance capital expenditures, working capital or other general corporate purposes. Pending such use, the net proceeds may be invested in short-term marketable securities or cash term deposits with highly rated institutions.

CAPITALIZATION

The following table sets forth our cash and cash equivalents and our capitalization as at June 30, 2020, on an actual basis and as adjusted to reflect the sale of the Notes and the application of the net proceeds as described in “Use of Proceeds”. This table should be read in conjunction with our unaudited condensed consolidated interim financial statements incorporated by reference in this prospectus supplement.

PRO FORMA EARNINGS COVERAGE

The following earnings coverage ratios have been prepared in accordance with Canadian securities law requirements and have been included in this prospectus supplement in accordance with Canadian disclosure requirements. They have been calculated on a consolidated basis using financial information prepared in accordance with IFRS, and have been adjusted to reflect the sale of the Notes and the application of the net proceeds as described in “Use of Proceeds”. The pro forma ratio for the year ended December 31, 2019 gives effect to the advances under our credit facilities outstanding as of June 30, 2020, as if these advances had occurred on January 1, 2019. The pro forma ratios set forth below do not give effect to changes in other financial liabilities since the respective dates indicated below as these would not, in the aggregate, materially affect the pro forma earnings coverage ratios. For purposes of these calculations, reported net earnings attributable to our shareholders have been increased by interest expense and income taxes. The earnings coverage ratios set forth below do not purport to be indicative of earnings coverage ratios for any future periods.

Period	Pro forma interest		Earnings before interest expense and income taxes		Earnings coverage ratio (1)
Year ended December 31, 2019	$	million	$	216.7 million		times annual interest expense
Twelve months ended June 30, 2020	$	million	$	62.8 million		times annual interest expense	(2)

(1) The ratios are equal to net earnings attributable to Methanex shareholders, adjusted as described above, divided by pro forma interest expense. These ratios do not purport to be indicative of actual earnings coverage ratios for any future period.

(2) The earnings coverage ratio for the twelve month period ended June 30, 2020 is less than one-to-one. $                 million of additional earnings before interest expense and income taxes would have been required to achieve a one-to-one earnings coverage ratio for this period.

S-23

DESCRIPTION OF THE NOTES

The Notes will be issued under the trust indenture, dated as of July 20, 1995, which was entered into between Methanex and The Bank of New York Mellon (formerly United States Trust Company of New York), as trustee (the “Trustee”), as currently supplemented. The Indenture is by its terms subject to and governed by the U.S. Trust Indenture Act of 1939, as amended. A copy of the Indenture has been filed with the SEC as an exhibit to the Registration Statement of which the accompanying prospectus forms a part. The following statements with respect to the Indenture and the Notes are brief summaries of certain provisions of the Indenture and do not purport to be complete. For a more complete description, including the definition of any terms used but not defined under this section, prospective investors should refer to the Indenture. Whenever we refer to particular provisions of the Indenture, those provisions are qualified in their entirety by reference to the Indenture. You should read the Indenture in its entirety, copies of which are available as described herein under the heading “Where You Can Find More Information”.

In this section, the words “Company”, “we”, “us”, “our” and “Methanex” refer only to Methanex Corporation and not to any of our subsidiaries or joint ventures.

General

The Notes will be issued initially in an aggregate principal amount of US$            and will mature on            ,            . The Notes will be our general unsecured obligations. We may issue additional notes of the same series under the Indenture from time to time after this offering, without the consent of the holders of the Notes. The Notes and any additional notes of this series subsequently issued under the Indenture will be treated as a single class for all purposes under the Indenture, including, without limitation, waivers, amendments, redemptions and offers to purchase.

Interest on the Notes will accrue at the rate of        % per annum and will be payable semi-annually on            and            of each year, commencing on            ,            , to the persons in whose names the Notes are registered at the close of business on the preceding             and            , respectively (whether or not a business day).

The Notes will provide for us to pay interest on overdue principal and, to the extent lawful, on overdue instalments of interest at the above rate per annum, plus 1%. Interest on the Notes will be computed on the basis of a 360-day year comprised of twelve 30-day months. The yearly rate of interest that is equivalent to the rate payable under the Notes is the rate payable multiplied by the actual number of days in the year and divided by 360 and is disclosed herein solely for the purpose of providing the disclosure required by the Interest Act (Canada).

Principal of, and premium, if any, and interest on, the Notes will be payable, and the Notes may be presented for registration of transfer and exchange, at the office or agency maintained by us for that purpose in the Borough of Manhattan, the City of New York, provided, however, that at our option, payment of interest may be made by check mailed to the address of the person entitled thereto at such address as shall appear in the register of Notes, and at the option of the registered holder of the Notes, by wire transfer to an account designated by the registered holder in writing at least ten days before the relevant payment date. The Trustee will initially act as registrar.

There will be no mandatory sinking fund payments for the Notes.

Ranking and Other Indebtedness

The Notes will be unsecured obligations of the Company and will rank equally with all of our other unsecured and unsubordinated Indebtedness (as defined in the accompanying prospectus) from time to time

S-24

outstanding. The Notes will be effectively subordinated to all Indebtedness and other liabilities of our subsidiaries (other than any applicable guarantor, for so long as its guarantee remains in effect) and subordinated to all secured Indebtedness and other secured liabilities of the Company, any applicable guarantor and our subsidiaries to the extent of the assets securing such Indebtedness and other liabilities. The Notes will rank pari passu with our US$250,000,000 aggregate principal amount of 5.25% notes due 2022, our US$300,000,000 aggregate principal amount of 4.25% notes due 2024, our US$700,000,000 aggregate principal amount of 5.25% notes due 2029, and our US$300,000,000 aggregate principal amount of 5.65% notes due 2044.

Redemption

Optional Redemption

Prior to            ,            (            months before maturity) (the “Early Call Date”), the Notes will be redeemable in whole or in part, at our option at any time, at a redemption price equal to the greater of: (1) 100% of the principal amount of the Notes being redeemed; and (2) the sum of the present values of the remaining scheduled payments of principal and interest that would be due if the Notes matured on the Early Call Date but for the redemption (exclusive of interest accrued to the date of redemption) discounted to the redemption date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus basis points in the case of the Notes, plus accrued and unpaid interest thereon to the date of redemption.

At any time on or after the Early Call Date, the Notes will be redeemable in whole or in part, at our option at any time, at a redemption price equal to 100% of the principal amount of the Notes being redeemed, plus in each case accrued and unpaid interest thereon to the date of redemption.

“Comparable Treasury Issue” means the United States Treasury security or securities selected by an Independent Investment Banker as having an actual or interpolated maturity comparable to the remaining term of the Notes to be redeemed (assuming for such purpose that the Notes matured on the Early Call Date) that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of a comparable maturity to the remaining term of such Notes (assuming for such purpose that the Notes matured on the Early Call Date).

“Comparable Treasury Price” means, with respect to any redemption date, (1) the average, as determined by the Independent Investment Banker of the Reference Treasury Dealer Quotations for such redemption date, after excluding the highest and lowest of such Reference Treasury Dealer Quotations, or (2) if the Independent Investment Banker obtains fewer than four such Reference Treasury Dealer Quotations, the average of all such quotations.

“Independent Investment Banker” means one of the Reference Treasury Dealers appointed by the Company or, if such firm is unwilling or unable to select a Comparable Treasury Price, an independent banking institution of national standing in the United States, appointed by the Company.

“Reference Treasury Dealer” means each of J.P. Morgan Securities LLC, BMO Capital Markets Corp., BNP Paribas Securities Corp. and RBC Capital Markets, LLC plus one other or its affiliate which is a primary U.S. Government securities dealers appointed by the Company after consultation with the Independent Investment Banker; provided, however, that if any of the foregoing or their affiliates shall cease to be a primary U.S. Government securities dealer in The City of New York (a “Primary Treasury Dealer”), the Company shall substitute therefor another Primary Treasury Dealer, if one is available.

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any redemption date, the average, as determined by the Independent Investment Banker, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Independent Investment Banker by such Reference Treasury Dealer at 3:30 p.m. New York time on the third Business Day preceding such redemption date.

S-25

“Treasury Rate” means, with respect to any redemption date, the rate per annum, as determined by the Independent Investment Banker, equal to the semi-annual equivalent yield to maturity or interpolated (on a day count basis) of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such redemption date.

Notice of any redemption will be given at least 30 days but not more than 60 days before the redemption date to each holder of Notes to be redeemed.

Unless the Company defaults in payment of the redemption price, on and after the redemption date interest will cease to accrue on the Notes or portions thereof called for redemption.

Redemption for Changes in Canadian Withholding Taxes

The Notes may be redeemed, at our option, at any time in whole but not in part, on not less than 30 days’ but not more than 60 days’ notice, at 100% of the principal amount thereof, plus accrued and unpaid interest (if any) to the date of redemption (subject to the right of holders of record on the relevant record date to receive interest due on the relevant interest payment date), in the event we have become or would become obligated to pay, on the next date on which any amount would be payable with respect to the Notes, any Additional Amounts as a result of a change in or an amendment to the laws (including any regulations promulgated thereunder) of Canada (or any political subdivision or taxing authority thereof or therein), or any change in or amendment to any official position regarding the application or interpretation of such laws or regulations, which change or amendment is announced or becomes effective on or after the date of this prospectus supplement.

Governing Law

The Indenture and the Notes will be governed by, and construed in accordance with, the laws of the State of New York.

MATERIAL INCOME TAX CONSIDERATIONS

Material U.S. Federal Income Tax Considerations

The following is a general summary of the material U.S. federal income tax consequences of the acquisition, ownership and disposition of Notes by U.S. Holders (as defined below) who purchase Notes offered hereby at the price indicated on the cover of this prospectus supplement and hold such Notes as capital assets, within the meaning of Section 1221 of the U.S. Internal Revenue Code of 1986, as amended (the “Code”). This discussion is based on existing provisions of the Code, final and temporary regulations promulgated thereunder (“Treasury Regulations”), administrative pronouncements or practice, judicial decisions, and interpretations of the foregoing, all as of the date of this offering, all of which are subject to change (possibly with retroactive effect). This discussion is not binding on the U.S. Internal Revenue Service (the “IRS”). No ruling has been or will be sought or obtained from the IRS with respect to any of the U.S. federal income tax consequences discussed herein. There can be no assurance that the IRS will not challenge any of the conclusions described herein or that a U.S. court will not sustain such challenge.

As used herein, a “U.S. Holder” is any beneficial owner of a Note that is (i) a citizen or individual resident of the United States as determined for U.S. federal income tax purposes; (ii) a corporation, or other entity taxable as a corporation for U.S. federal income tax purposes, created or organized in or under the laws of the United States or any of its political subdivisions; (iii) an estate the income of which is subject to U.S. federal income taxation regardless of its source; or (iv) a trust if (a) a court within the United States is able to exercise primary supervision over the administration of the trust and one or more U.S. persons have the authority to control all substantial decisions of the trust, or (b) the trust has a valid election in effect under applicable Treasury Regulations to be treated as a U.S. person. Partnerships (including entities classified as partnerships for U.S. federal income tax purposes) are not U.S. Holders. If a partnership holds a Note, the U.S. federal income tax treatment of a partner generally will depend upon the status of such partner and upon the activities of the partnership. You are urged to consult your own tax advisor if you are a U.S. person and a partner of a partnership holding a Note.

This discussion is not a complete analysis or description of all of the possible tax consequences of the acquisition, ownership and disposition of the Notes. This discussion does not address any U.S. federal alternative minimum tax, U.S. federal estate, gift, or other non-income tax, or state, local or non-U.S. tax consequences of the acquisition, ownership and disposition of the Notes. In addition, this discussion does not address the U.S. federal income tax consequences to U.S. Holders subject to special rules, including U.S. Holders that are: (i) banks, financial institutions or insurance companies; (ii) regulated investment companies or real estate investment trusts; (iii) brokers or dealers in securities or currencies or traders in securities that elect to use a mark-to-market method of accounting; (iv) tax-exempt organizations, qualified retirement plans, individual retirement accounts or other tax-deferred accounts; (v) holders that hold a Note as part of a hedge, straddle, conversion transaction or a synthetic security or other integrated transaction; (vi) holders that have a “functional currency” other than the U.S. dollar; (vii) holders subject to special tax accounting rules as a result of any item of gross income with respect to the Notes being taken into account in an “applicable financial statement” (as defined in Section 451 of the Code); or (viii) U.S. expatriates.

YOU ARE URGED TO CONSULT YOUR OWN TAX ADVISOR WITH RESPECT TO THE APPLICATION OF THE U.S. FEDERAL TAX LAWS TO YOUR PARTICULAR CIRCUMSTANCES AS WELL AS ANY TAX CONSEQUENCES ARISING UNDER THE LAWS OF ANY STATE, LOCAL, NON-U.S. OR OTHER TAXING JURISDICTION OR UNDER ANY APPLICABLE TAX TREATY.

Notes Subject to Contingency

We will be required to make an offer to repurchase all of the Notes at a price equal to 101% of their principal amount plus accrued and unpaid interest upon the occurrence of a Change of Control Triggering Event. See “Description of Debt Securities — Certain Covenants — Change of Control” in the accompanying prospectus.

S-28

It is possible that this requirement to offer to repurchase the Notes at a premium could implicate the provisions of Treasury Regulations relating to “contingent payment debt instruments”. If the Notes were characterized as contingent payment debt instruments, you might, among other things, be required to accrue interest income in different amounts and at different times than as otherwise described herein, and to treat any gain recognized on the sale or other disposition of a Note as ordinary income rather than as capital gain.

We intend to take the position that the likelihood of a Change of Control Triggering Event is remote, and thus, that the Notes should not be treated as contingent payment debt instruments. Our determination that such a contingency is remote is binding on you unless you disclose your contrary position in the manner required by applicable Treasury Regulations. Our determination, however, is not binding on the IRS, and the IRS could challenge this determination.

The remainder of this disclosure assumes that our determination that such a contingency is remote is correct. The Treasury Regulations applicable to contingent payment debt instruments have not been the subject of authoritative interpretation, however, and the scope of the Treasury Regulations is not certain. You are urged to consult your tax advisor regarding the possible application of the special rules related to contingent payment debt instruments to the Notes.

Payments of Interest

You will be taxed on interest on your Notes (including any amounts withheld and any Additional Amounts paid in respect of withholding taxes imposed on the Notes) as ordinary income at the time you receive the interest or when the interest accrues, depending on your method of accounting for U.S. federal income tax purposes. You may be entitled to deduct or credit any taxes withheld subject to certain limitations of the U.S. foreign tax credit rules. For this purpose, interest paid on the Notes is income from sources outside the United States for purposes of computing the foreign tax credit allowable to a U.S. Holder. Interest income on the Notes generally will be considered either “passive category income” or “general category income” for U.S. foreign tax credit purposes. The rules governing the foreign tax credit are complex, and you are urged to consult your tax advisor regarding the availability of the credit under your particular circumstances.

Notes with a term that exceeds one year will be treated as issued with original issue discount (“OID”) if the stated redemption price at maturity of the Note exceeds its issue price by more than the de minimis amount of ¹⁄₄ of 1% of the “stated redemption price at maturity” multiplied by the number of complete years from the issue date of the Note to its maturity. A Note’s “issue price” generally is the first price at which a substantial amount of Notes included in the issue of which the Note is a part is sold to persons other than bond houses, brokers, or similar persons or organizations acting in the capacity of underwriters, placement agents or wholesalers. The “stated redemption price at maturity” of a Note is the total of all payments provided by the Note that are not payments of “qualified stated interest.” Generally, an interest payment on a Note is “qualified stated interest” if it is one of a series of stated interest payments on a Note that are unconditionally payable at least annually at a single fixed rate, with certain exceptions for lower rates paid during some periods, applied to the outstanding principal amount of the note.

It is not expected that the Notes will be issued with OID. If, however, the stated redemption price of a Note exceeds its issue price by more than a de minimis amount, you will be required to treat such excess amount as OID, which is treated for U.S. federal income tax purposes as accruing over the term of the Note as interest income to you. Your adjusted tax basis in a Note would be increased by the amount of any OID included in your gross income. In compliance with Treasury Regulations, if we determine that the Notes have OID, we will provide certain information to the IRS and/or you that is relevant to determining the amount of OID in each accrual period.

Sale, Exchange and Retirement of the Notes

You generally will recognize capital gain or loss on the sale, exchange or retirement of your Notes equal to the difference between the amount you realize on the sale, exchange, redemption, retirement or other taxable

S-29

disposition of the Notes, excluding any amounts attributable to accrued but unpaid interest (which will generally be taxed as ordinary interest income, unless previously taken into income), and your adjusted tax basis in your Notes at the time of the sale, exchange, redemption, retirement or other taxable disposition. Your adjusted tax basis in a Note generally will be the amount that you paid for the Note decreased by the amount of any payments (other than payments of stated interest) on the Note. Such gain or loss generally will constitute long-term capital gain or loss if at the time of the sale, exchange, redemption, retirement or other taxable disposition of the Note you held the Note for more than one year, and otherwise will be short-term capital gain or loss. Under current law, net long-term capital gains of non-corporate U.S. Holders (including individuals) are, generally, taxed at lower rates than items of ordinary income. The deductibility of capital losses is subject to limitations. Any such gain or loss generally will be treated as U.S. source income or loss.

Information Reporting and Backup Withholding

In general, information reporting requirements apply to certain payments to U.S. Holders of principal of, and interest on, a Note and the receipt of proceeds on the sale or other disposition (including a retirement or redemption) of a Note before maturity, in each case when made within the United States or through certain U.S.-related intermediaries. Additionally, if a U.S. Holder does not otherwise qualify for an exemption and fails to (1) furnish its taxpayer identification number, (2) certify that such number is correct, (3) certify that such U.S. Holder is not subject to backup withholding, and (4) otherwise comply with the applicable requirements of the backup withholding rules, such U.S. Holder will be subject to backup withholding on such payments and proceeds, currently at a rate of 24%.

Certain U.S. Holders are generally not subject to backup withholding and information reporting requirements provided their exemption from backup withholding and information reporting are properly established. Backup withholding is not an additional U.S. federal income tax. Any amounts withheld under the U.S. backup withholding rules will be allowed as a credit against your U.S. federal income tax liability, if any, or will be refunded by the IRS to the extent it exceeds such liability, if you furnish required information to the IRS in a timely manner. You are urged to consult your tax advisor regarding the application of backup withholding, the availability of an exemption from backup withholding and the procedure for obtaining such an exemption, if available.

In addition, U.S. Holders should be aware of annual reporting requirements with respect to the holding of certain foreign financial assets, including securities of foreign issuers that are not held in an account maintained by certain types of financial institutions, if the aggregate value of all of such assets exceeds US$50,000. You are urged to consult your tax advisor regarding the application of the information reporting rules to the Notes and the application of the reporting requirements to your particular situation.

Additional Tax on Investment Income

Certain U.S. Holders who are individuals, estates or trusts and whose income exceeds certain thresholds generally will be required to pay an additional 3.8% tax on all or a portion of their “net investment income,” which includes, among other things, interest income and capital gains from the sale or other disposition of a Note, subject to certain limitations and exceptions. U.S. Holders are urged to consult their own tax advisors regarding the application of this additional tax to their investment in the Notes.

THE U.S. FEDERAL INCOME TAX DISCUSSION SET FORTH ABOVE IS INCLUDED FOR GENERAL INFORMATION ONLY AND MAY NOT BE APPLICABLE DEPENDING UPON YOUR PARTICULAR SITUATION. YOU ARE URGED TO CONSULT YOUR OWN TAX ADVISOR WITH RESPECT TO THE TAX CONSEQUENCES TO YOU OF THE ACQUISITION, OWNERSHIP AND DISPOSITION OF THE NOTES INCLUDING THE TAX CONSEQUENCES UNDER STATE, LOCAL, NON-U.S. AND OTHER TAX LAWS AND THE POSSIBLE EFFECTS OF CHANGES IN U.S. OR OTHER TAX LAWS.

Material Canadian Federal Income Tax Considerations

In the opinion of McCarthy Tétrault LLP, our Canadian counsel, the following is, as of the date hereof, a summary of the principal Canadian federal income tax considerations generally applicable to a holder who acquires Notes, as beneficial owner, pursuant to this offering and who, at all relevant times, for the purposes of the Income Tax Act (Canada) (the “Canadian Tax Act”) and any applicable income tax treaty or convention (i) is not resident or deemed to be resident in Canada, (ii) deals at arm’s length with Methanex, any successor to Methanex, and any transferees resident or deemed to be resident in Canada to whom the holder disposes of Notes, (iii) does not use or hold, and is not deemed to use or hold, Notes in connection with a business, including an adventure or concern in the nature of trade, carried on, or deemed to be carried on, in Canada, (iv) is entitled to receive all payments (including interest and principal) made on the Notes, (v) is not a “specified shareholder” (as defined in subsection 18(5) of the Canadian Tax Act) of Methanex or a person that does not deal at arm’s length with a “specified shareholder” of Methanex, and (vi) is not an insurer carrying on an insurance business in Canada and elsewhere (each, a “Holder”). This summary assumes that no amount paid or payable as, or on account or in lieu of payment of, interest will be in respect of a debt or other obligation to pay an amount to a person with whom Methanex does not deal at arm’s length within the meaning of the Canadian Tax Act. Any holder to which this summary does not apply should consult its own tax advisors with respect to the tax consequences of acquiring, holding and disposing of Notes.

This summary is based upon the current provisions of the Canadian Tax Act and regulations promulgated thereunder (the “Regulations”) and on counsel’s understanding of the current published administrative and assessing practices and policies of the Canada Revenue Agency. This summary takes into account all specific proposals to amend the Canadian Tax Act and the Regulations publicly announced by or on behalf of the Minister of Finance (Canada) prior to the date hereof (the “Proposed Amendments”). This summary is not exhaustive of all Canadian federal income tax considerations and, except as mentioned above, does not take into account or anticipate possible changes in the law or in administrative or assessing practices and policies whether by legislative, regulatory, administrative or judicial action. This summary does not take into account foreign (i.e. non-Canadian) tax considerations or Canadian provincial or territorial tax considerations which may vary from the Canadian federal income tax considerations described herein. No assurance can be given that the Proposed Amendments will be enacted as proposed or at all.

UNDERWRITING

Subject to the terms and conditions set forth in the underwriting agreement dated                    , 2020, each of the underwriters named below, for whom J.P. Morgan Securities LLC is acting as representative, has severally agreed to purchase, and we have agreed to sell to each underwriter, the respective principal amounts of Notes as set forth opposite the name of each underwriter below.

Underwriter	Principal Amount
J.P. Morgan Securities LLC		US$
BMO Capital Markets Corp.
BNP Paribas Securities Corp.
RBC Capital Markets, LLC
Total		US$

The underwriting agreement provides that the obligations of the underwriters to purchase the Notes are subject to approval of certain legal matters by counsel and to certain other conditions. The underwriters are obligated to purchase all of the Notes if they purchase any of the Notes.

We have been advised by the underwriters that the underwriters propose initially to offer some of the Notes to the public at the public offering price set forth on the cover page of this prospectus supplement and may offer some of the Notes to certain dealers at the public offering price less a concession not in excess of        % of the principal amount of the Notes. The underwriters may allow, and these dealers may re-allow, a discount not in excess of        % of the principal amount of the Notes on sales of the Notes to certain other dealers. After the initial offering of the Notes to the public, the underwriters may change the public offering price and concessions.

The following table shows the underwriting commissions that we are to pay to the underwriters in connection with this offering (expressed as a percentage of the principal amount of the Notes).

	Paid by Methanex
Per Note		%

In connection with the offering of the Notes, the underwriters, or their respective affiliates, may purchase and sell the Notes in the open market. These transactions may include short sales, stabilizing transactions and purchases to cover positions created by short sales. Short sales involve the sale by the underwriters of a greater number of Notes than they are required to purchase in the offering. Stabilizing transactions consist of certain bids or purchases made for the purpose of preventing or retarding a decline in the market price of the Notes while the offering is in progress.

The underwriters also may impose a penalty bid. This occurs when a particular underwriter repays to the other underwriters a portion of the underwriting discount received by it because the representatives have repurchased Notes sold by or for the account of such underwriter in stabilizing or short covering transactions.

Any of these activities may cause the price of the Notes to be higher than the price that otherwise would exist in the open market in the absence of such transactions. These transactions may be effected in the over-the-counter market or otherwise and, if commenced, may be discontinued at any time. Neither we nor any of the underwriters make any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the price of the Notes. In addition, neither we nor any of the underwriters make any representation that any of the underwriters will engage in such transactions, or that such transactions, once begun, will not be discontinued without notice.

We estimate that our total expenses of this offering, excluding underwriting commissions, will be approximately US$            .

S-32

The underwriters and their respective affiliates are full service financial institutions engaged in various activities, which may include securities trading, commercial and investment banking, financial advisory, investment management, investment research, principal investment, hedging, financing and brokerage activities.

Certain of the underwriters and their affiliates have performed certain investment banking, advisory or general financing and banking services for us and our affiliates from time to time, for which they have received customary fees and expenses. Certain of the underwriters and their affiliates may, from time to time, engage in transactions with and perform services for us and our affiliates in the ordinary course of their business. Certain of the underwriters are affiliates of banks which are lenders to us under our credit facilities and to certain of our subsidiaries under certain debt obligations. Consequently, we may be considered to be a connected issuer of the underwriters under applicable Canadian securities legislation. We are in compliance with the terms of the agreement governing the credit facilities and our subsidiaries are in compliance with the terms of the agreements governing their debt obligations. See “Capitalization”. None of the underwriters nor the banks affiliated with them was involved in our decision to distribute the Notes offered hereby. The underwriters negotiated the public offering price of the Notes with us.

We have agreed to indemnify the several underwriters against certain liabilities, including certain liabilities under the Securities Act.

In the ordinary course of their various business activities, the underwriters and their respective affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans and/or credit default swaps) for their own account and for the accounts of their customers, and such investment and securities activities may involve our securities and/ or instruments. If any of the underwriters or their affiliates have a lending relationship with us, certain of those underwriters or their affiliates routinely hedge, certain other of those underwriters or their affiliates are likely to hedge and certain other of those underwriters or their affiliates may hedge, their credit exposure to us consistent with their customary risk management policies. Typically, these underwriters and their affiliates would hedge such exposure by entering into transactions which consist of either the purchase of credit default swaps or the creation of short positions in our securities, including potentially the Notes offered hereby. Any such credit default swaps or short positions could adversely affect future trading prices of the Notes offered hereby. The underwriters and their respective affiliates may also make investment recommendations and/or publish or express independent research views in respect of such securities or instruments and may at any time hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.

The Notes are a new issue of securities with no established trading market. We do not intend to list the Notes on any securities exchange or to include them in any automated quotation system. We cannot assure you that the Notes will have a liquid trading market. We have been advised by the underwriters that they intend to make a market in the Notes, but they are not obligated to do so and may discontinue such market-making at any time without notice.

The Notes are offered for sale in those jurisdictions in the United States, Europe and elsewhere where it is lawful to make such offers, only in accordance with the offering restrictions applicable in such jurisdictions.

This prospectus supplement does not qualify the distribution of any Notes which may be offered or sold in any province or territory of Canada, including the Province of British Columbia, and any such sales will only be made pursuant to private placement exemptions from the prospectus requirements of the securities laws of such provinces and territories.

The audit report covering the consolidated financial statements refers to the Company’s adoption of IFRS 16 Leases related to the accounting for leases effective January 1, 2019. The audit report covering the consolidated financial statements also refers to the restatement of the 2018 consolidated financial statements, as described in Note 25 to the consolidated financial statements.

The audit report on the effectiveness of internal control over financial reporting as of December 31, 2019, expresses an opinion that Methanex Corporation did not maintain effective internal control over financial reporting as of December 31, 2019 because of the effect of a material weakness on the achievement of the objectives of the control criteria and contains an explanatory paragraph that states ineffective controls over research and technical accounting analysis have been identified and included in management’s assessment.

Amendment No. 1 dated September 9, 2020 to the Short Form Base Shelf Prospectus dated August 22, 2019 (the “Amended Prospectus”)

This amendment, together with the short form base shelf prospectus dated August 22, 2019, constitutes a public offering of these securities only in those jurisdictions where they may be lawfully offered for sale and therein only by persons permitted to sell such securities. No securities regulatory authority has expressed an opinion about these securities and it is an offence to claim otherwise.

METHANEX CORPORATION

US$1,500,000,000

Debt Securities

Reference is made to the short form base shelf prospectus dated August 22, 2019 (the “Prospectus”) of Methanex Corporation (“Methanex” or “the Company”).

The Prospectus is amended to increase the aggregate amount of Offered Debt Securities that may be offered from time to time under the Prospectus from US$1,200,000,000 to US$1,500,000,000. In particular, the Prospectus is amended by deleting all references to “US$1,200,000,000” contained within the Prospectus and substituting therefor “US$1,500,000,000”.

As of the date of this amendment, Methanex has distributed Offered Debt Securities under the Prospectus having an aggregate principal amount of US$700,000,000.

None of the U.S. Securities and Exchange Commission (the “SEC”), the British Columbia Securities Commission (the “BCSC”) nor any state, provincial or territorial securities commission has approved or disapproved of these securities or determined if the Amended Prospectus is truthful or complete. Any representation to the contrary is a criminal offence.

We are permitted, under a multi-jurisdictional disclosure system adopted by the United States and Canada, to prepare the Prospectus, including this amendment, in accordance with the disclosure requirements of Canada, which are different from United States disclosure requirements. The financial statements included or incorporated herein have been prepared in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board. As a result, they may not be comparable to financial statements of United States companies.

Owning the Offered Debt Securities may subject you to tax consequences both in the United States and Canada. The Prospectus, as amended, or any applicable prospectus supplement may not describe these tax consequences fully. You should read the tax discussion in any applicable prospectus supplement and should consult with your own tax advisor with respect to your own particular circumstances.

Your ability to enforce civil liabilities under the United States federal securities laws may be affected adversely by the fact that we are incorporated in Canada, most of our officers and directors and some of the experts named in the Prospectus, as amended, are not residents of the United States, and many of our assets and all or a substantial portion of the assets of such persons are located outside the United States.

US$1,200,000,000

Debt Securities

We may from time to time offer up to an aggregate principal amount of US$1,200,000,000 of debt securities during the 25 month period that this short form base shelf prospectus (this “Prospectus”), including any amendments hereto, remains valid. The debt securities may be offered separately or together, in one or more series, in amounts, at prices and on other terms to be determined based on market conditions at the time of issuance and set forth in an accompanying prospectus supplement.

We will provide the specific terms of the debt securities in respect of which this Prospectus is being delivered (the “Offered Debt Securities”) and all information omitted from this Prospectus in supplements to this Prospectus that will be delivered to purchasers of Offered Debt Securities together with this Prospectus. Each prospectus supplement will be incorporated by reference into this Prospectus for the purposes of securities legislation as of the date of the prospectus supplement and only for the purposes of the distribution of the Offered Debt Securities to which the prospectus supplement pertains. You should read this Prospectus and any applicable prospectus supplement carefully before you invest in Offered Debt Securities.

Neither the United States Securities and Exchange Commission (the “SEC”) nor any state securities regulator has approved or disapproved of any debt securities offered pursuant to this Prospectus or determined if this Prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

We are permitted, under a multijurisdictional disclosure system adopted by the United States and Canada, to prepare this Prospectus in accordance with Canadian disclosure requirements, which are different from U.S. disclosure requirements. Our financial statements, which are incorporated by reference herein, have been prepared, for all periods presented, in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board (“IFRS”). As a result, they may not be comparable to financial statements of U.S. companies.

Owning the Offered Debt Securities may subject you to tax consequences both in the United States and Canada. This Prospectus or any applicable prospectus supplement may not describe these tax consequences fully. You should read the tax discussion in any applicable prospectus supplement and should consult with your own tax advisor with respect to your own particular circumstances.

Your ability to enforce civil liabilities under U.S. federal securities laws may be affected adversely because we are incorporated in Canada, most of our officers and directors and all of the experts named in this Prospectus are not residents of the United States, and many of our assets and all or a substantial portion of the assets of such persons are located outside of the United States.

There is no market through which the Offered Debt Securities may be sold and purchasers may not be able to resell Offered Debt Securities purchased under this Prospectus. This may affect the pricing of the Offered Debt Securities on the secondary market, the transparency and availability of trading prices, the liquidity of the Offered Debt Securities and the extent of issuer regulation. See “Risk Factors.”

We may sell the Offered Debt Securities to or through underwriters or dealers, and also may sell Offered Debt Securities to one or more other purchasers directly or through agents. In addition, we may issue the Offered Debt Securities pursuant to one or more exchange offers for our previously issued debt securities. This Prospectus only qualifies under the securities laws of British Columbia the distribution of the Offered Debt Securities in the United States and elsewhere outside of Canada. This Prospectus does not qualify the distribution of any Offered Debt Securities which may be offered or sold in any province or territory of Canada, including the Province of British Columbia, and any such sales will only be made pursuant to private placement exemptions from the prospectus requirements of the securities laws of such provinces or territories. See “Plan of Distribution”. Each prospectus supplement will set forth the names of any underwriters, dealers or agents involved in the offering of the Offered Debt Securities and will set forth the terms of the offering of Offered Debt Securities, including, to the extent applicable, the proceeds to the Company, the principal amounts, if any, to be purchased by underwriters, the underwriting discounts or commissions, and any other discounts or concessions to be allowed or reallowed to dealers. No underwriter has been involved in the preparation of this Prospectus or performed any review of the contents of this Prospectus.

CAUTION REGARDING FORWARD-LOOKING STATEMENTS

This Prospectus, and certain documents incorporated by reference in this Prospectus, contain forward-looking information and forward-looking statements, as defined in applicable securities laws (collectively referred to as “forward-looking statements”). These statements relate to future events or our future performance. All statements other than statements of historical fact are forward-looking statements. The use of any of (or variations of any of) the words “anticipate”, “plan”, “continue”, “estimate”, “expect”, “may”, “will”, “project”, “predict”, “potential”, “should”, “believe”, “target”, “plan”, “predict” and similar expressions are intended to identify forward-looking statements. Forward-looking statements involve known and unknown risks, uncertainties and other factors which may cause actual results or events to differ materially from those implied by such forward-looking statements. These statements speak only as of the date of this Prospectus or as of the date specified in the documents incorporated by reference in this Prospectus, as the case may be.

More particularly and without limitation, any statements regarding the following are forward-looking statements:

• expected demand for methanol and its derivatives;

• expected new methanol supply or restart of idled capacity and timing for start-up of the same;

• expected shutdowns (either temporary or permanent) or restarts of existing methanol supply (including our own facilities), including, without limitation, the timing and length of planned maintenance outages;

• expected methanol and energy prices;

• expected levels of methanol purchases from traders or other third parties;

• expected levels, timing and availability of economically priced natural gas supply to each of our plants;

• capital committed by third parties towards future natural gas exploration and development in the vicinity of our plants;

• our expected capital expenditures;

• anticipated operating rates of our plants;

• expected operating costs, including natural gas feedstock costs and logistics costs;

• expected tax rates or resolutions to tax disputes;

• expected cash flows, earnings capability and share price;

• availability of committed credit facilities and other financing;

• our ability to meet covenants or obtain or continue to obtain waivers associated with our long-term debt obligations, including without limitation, the Egypt limited recourse debt facilities that have conditions associated with the payment of cash or other distributions and the finalization of certain land title registrations and related mortgages which require actions by Egyptian governmental entities;

• expected impact on our results of operations in Egypt or our financial condition as a consequence of actions taken or inaction by Egyptian governmental entities;

• our shareholder distribution strategy and anticipated distributions to shareholders;

• commercial viability and timing of, or our ability to execute, future projects, plant restarts, capacity expansions, plant relocations, or other business initiatives or opportunities, including our Geismar 3 Project;

• our financial strength and ability to meet future financial commitments;

• expected global or regional economic activity (including industrial production levels);

4

• expected outcomes of litigation or other disputes, claims and assessments; and

• expected actions of governments, governmental agencies, gas suppliers, courts, tribunals or other third parties.

We believe that we have a reasonable basis for making such forward-looking statements. The forward-looking statements in this Prospectus and certain documents incorporated by reference in this Prospectus are based on our experience, our perception of trends, current conditions and expected future developments as well as other factors. Certain material factors or assumptions were applied in drawing the conclusions or making the forecasts or projections that are included in these forward-looking statements, including, without limitation, future expectations and assumptions concerning the following:

• the supply of, demand for, and price of methanol, methanol derivatives, natural gas, coal, oil and oil derivatives;

• our ability to procure natural gas feedstock on commercially acceptable terms;

• operating rates of our facilities;

• receipt or issuance of third-party consents or approvals, including, without limitation, governmental registrations of land title and related mortgages in Egypt and governmental approvals related to rights to purchase natural gas;

• the establishment of new fuel standards;

• operating costs, including natural gas feedstock and logistics costs, capital costs, tax rates, cash flows, foreign exchange rates and interest rates;

• the availability of committed credit facilities and other financing;

• timing of completion and cost of our Geismar 3 Project;

• global and regional economic activity (including industrial production levels);

• absence of a material negative impact from major natural disasters;

• absence of a material negative impact from changes in laws or regulations;

• absence of a material negative impact from political instability in the countries in which we operate; and

• enforcement of contractual arrangements and ability to perform contractual obligations by customers, natural gas and other suppliers and other third parties.

However, forward-looking statements, by their nature, involve risks and uncertainties that could cause actual results to differ materially from those contemplated by the forward-looking statements. The risks and uncertainties primarily include those attendant with producing and marketing methanol and successfully carrying out major capital expenditure projects in various jurisdictions, including; without limitation:

• conditions in the methanol and other industries including fluctuations in the supply, demand and price for methanol and its derivatives, including demand for methanol for energy uses;

• the price of natural gas, coal, oil and oil derivatives;

• our ability to obtain natural gas feedstock on commercially acceptable terms to underpin current operations and future production growth opportunities;

• the ability to carry out corporate initiatives and strategies;

• actions of competitors, suppliers, and financial institutions;

• conditions within the natural gas delivery systems that may prevent delivery of our natural gas supply requirements;

5

• our ability to meet timeline and budget targets for our Geismar 3 Project, including cost pressures arising from labour costs;

• competing demand for natural gas, especially with respect to any domestic needs for gas and electricity;

• actions of governments and governmental authorities, including, without limitation, the implementation of policies or other measures that could impact the supply of or demand for methanol or its derivatives;

• changes in laws or regulations;

• import or export restrictions, anti-dumping measures, increases in duties, taxes and government royalties, and other actions by governments that may adversely affect our operations or existing contractual arrangements;

• worldwide economic conditions; and

• other risks described in the documents incorporated by reference in this Prospectus, including, without limitation, under the heading “Risk Factors and Risk Management” in our Annual MD&A.

We caution you that the foregoing list of important factors and assumptions is not exhaustive. Events or circumstances could cause our actual results to differ materially from those estimated or projected and expressed in, or implied by, these forward-looking statements.

Having in mind these and other factors, you are cautioned not to place undue reliance on forward-looking statements. They are not a substitute for the exercise of one’s own due diligence and judgment. The outcomes implied by forward-looking statements may not occur and we do not undertake to update forward-looking statements except as required by applicable securities laws. You should also carefully consider the matters discussed under “Risk Factors” in this Prospectus.

RISK FACTORS

An investment in the Offered Debt Securities involves risk. Before deciding whether to invest in the Offered Debt Securities, you should consider carefully the risks described below as well as the other information contained and incorporated by reference in this Prospectus (including subsequent documents incorporated by reference in this Prospectus) and, if applicable, those described in a prospectus supplement relating to a specific offering of Offered Debt Securities. These are not the only risks and uncertainties that we face. Additional risks not presently known to us or that we currently consider immaterial may also materially and adversely affect us. If any of the events identified in these risks and uncertainties were to actually occur, our business, financial condition or results of operations could be materially harmed.

The methanol industry is subject to commodity price volatility and supply and demand uncertainty.

The methanol business is a highly competitive commodity industry and prices are affected by supply and demand fundamentals. Methanol prices have historically been, and are expected to continue to be, characterized by cyclicality. Factors influencing supply and demand for methanol and related risks are found below. We are not able to predict future methanol supply and demand balances, global economic activity, methanol prices or energy prices, all of which are affected by numerous factors beyond our control. Since methanol is the only product we produce and market, a decline in the price of methanol has a significant negative effect on our results of operations and financial condition.

Future demand for methanol may be adversely affected by energy prices, global economic growth rates and government regulations and policies.

Energy Prices

Approximately 45% of methanol demand is from energy-related applications. These include methanol-to-olefins, methyl tertiary-butyl ether, direct blending of methanol into gasoline (primarily in China), di-methyl ether, biodiesel, methanol-to-gasoline, industrial boilers and marine fuel. Over the past number of years, methanol demand growth has been led by strong demand from these applications, in part, as relatively high oil prices generated an economic incentive to substitute lower cost methanol for petroleum products or as a feedstock in energy-related products. Over the past few years, the fastest growing application where methanol serves as a substitute for an energy product has been methanol-to-olefins, where methanol is an alternative feedstock in the production of olefins. Methanol-to-olefins use makes up approximately 14% of total methanol demand. Olefins have historically been made from ethane and naptha which are energy based feedstocks.

Methanol can also be blended directly with gasoline, and di-methyl ether (a methanol derivative) can be blended with liquefied petroleum gas (propane). Because of this relationship, methanol demand is sensitive to the pricing of these energy products, which in turn are generally linked to global energy prices.

We cannot provide assurance that energy prices will not negatively impact methanol demand growth, which could have an adverse effect on our results of operations and financial condition.

Global Economic Growth Rates

Approximately 55% of methanol demand is from traditional chemical applications. As these applications are used to manufacture products used in a wide variety of industrial products and consumer goods, the rate of growth in demand for methanol from these applications tends to be correlated with overall global economic growth. Any slowdown in the global or regional economies can negatively impact demand for methanol and have a detrimental impact on methanol prices.

Government Regulations and Policies

Changes in environmental, health and safety laws, regulations or requirements could impact methanol demand. The United States Environmental Protection Agency (“EPA”) has traditionally evaluated the human

7

health effects of methanol as part of a standard review of chemicals under its Integrated Risk Information System (“IRIS”), a database of chemical health effects. More recently, the EPA has indicated a preference to evaluate chemicals under the Toxic Substances Control Act (“TSCA”); however, methanol has not been selected for review under TSCA. No authoritative body has classified methanol as a carcinogen. A draft assessment for methanol was released by the EPA in 2010 classifying methanol as “Likely to be Carcinogenic to Humans.” In 2011, the EPA divided the draft assessment for methanol into cancer and non-cancer assessments. In September 2013, the EPA released the final non-cancer assessment, in which it established the maximum ingestion and inhalation levels for methanol that it claims will not result in adverse health impacts. The timeline for the final cancer assessment remains unknown, and no activity on the cancer assessment for methanol is currently contained on the EPA’s work plan. We are unable to determine whether the current draft classification will be maintained in the final cancer assessment or if this will lead other government agencies to reclassify methanol. Any reclassification could reduce future methanol demand, which could have an adverse effect on our results of operations and financial condition.

In 2018, methanol demand for the production of formaldehyde represented approximately 30% of global demand. The largest use for formaldehyde is as a component of urea-formaldehyde and phenol-formaldehyde resins, which are used in adhesives for plywood, particleboard, oriented strand board, medium-density fibreboard and other reconstituted or engineered wood products.

There is also demand for formaldehyde as a raw material for engineering plastics and in the manufacture of a variety of other products, including elastomers, paints, building products, foams, polyurethane and automotive products.

The current EPA IRIS carcinogenicity classification for formaldehyde is “Likely to be Carcinogenic to Humans;” however, the EPA is reviewing this classification for formaldehyde as part of a standard review of chemicals. There is no firm timeline for the final assessment. In 2010, the EPA released its draft formaldehyde assessment, proposing formaldehyde as “Known to be Carcinogenic to Humans.” The National Toxicology Program (“NTP”) lists formaldehyde as “Known to be a Human Carcinogen” under the NTP Report on Carcinogens. EPA uses IRIS assessments as a basis for regulatory actions such as restricting emissions from products containing formaldehyde. The EPA continues to develop a revised IRIS assessment of formaldehyde. In 2019, formaldehyde was selected as a priority chemical for review under TSCA with an anticipated final risk evaluation date of December 2022.

In 2009, the US National Cancer Institute (“NCI”) published a report on the health effects of occupational exposure to formaldehyde and a possible link to leukemia, multiple myeloma and Hodgkin’s disease. The NCI report concluded that there may be an increased risk of cancers of the blood and bone marrow related to a measure of peak formaldehyde exposure. The NCI report was the first part of an update of the 2004 NCI study that indicated possible links between formaldehyde exposure and nasopharyngeal cancer and leukemia. The International Agency for Research on Cancer also concluded that there is sufficient evidence in humans of a causal association of formaldehyde with leukemia. In 2011, the U.S. Department of Health and Human Services’ National Toxicology Program released its 12th Report on Carcinogens, modifying its listing of formaldehyde from “Reasonably Anticipated to be a Human Carcinogen” to “Known to be a Human Carcinogen.”

We are unable to determine at this time if the EPA or other governments or government agencies will reclassify formaldehyde or what limits could be imposed related to formaldehyde emissions in the United States or elsewhere. Any such actions could reduce future methanol demand for use in producing formaldehyde, which could have an adverse effect on our results of operations and financial condition.

Increase in competitively priced methanol supply may have a negative impact on the methanol price.

An increase in competitively priced methanol supply, all else equal, can displace supply from higher cost producers and have a negative impact on methanol price. Methanol supply is influenced by the cost of production

8

including the availability and cost of raw materials including coal and natural gas, freight costs, capital costs and government policies. Methanol supply can become available from the construction of new methanol plants, by restarting idle methanol plants, by carrying out major expansions of existing plants or by debottlenecking existing plants to increase their production capacity.

Approximately 4.0 million tonnes of new annualized capacity outside of China was introduced in 2018, including the 1.8 million tonne Natgasoline methanol plant which commenced operation late in the second quarter in Beaumont, Texas, the 1.7 million tonne Marjan methanol plant that started up late in the third quarter in Iran and the 0.5 million tonne Shchekinoazot methanol plant in Russia. In China, we estimate that approximately 2.7 million tonnes of net new production capacity was added in 2018. In the first quarter of 2019, the Kaveh Methanol Company in Iran announced completion of their 2.3 million tonne plant. We estimate that approximately 1.3 million tonnes of net new annual production capacity in China has been added in the first half of 2019.

Over the next few years, the majority of large-scale capacity additions outside of China are expected to be in the Americas and the Middle East. Caribbean Gas Chemical Limited is constructing a 1.0 million tonne plant in Trinidad with announced production targeted for late 2019. Yuhuang Chemical Industries Inc. announced it is progressing plans to complete a 1.7 million tonne project in St. James Parish, Louisiana with an announced target completion date in 2020. We recently announced a final investment decision to construct a 1.8 million tonne plant which will be our third plant in Geismar, Louisiana, with production targeted for the second half of 2022. There are other large-scale projects under discussion in North America; however, we believe that there has been limited committed capital to date. There are a number of projects under construction in Iran, including the Bushehr plant, that we continue to monitor. We anticipate that new non-integrated capacity additions in China will be modest due to a continuing degree of restrictions placed by the Chinese government on new standalone coal-based capacity additions. We expect that production from new capacity in China will be consumed in that country.

We cannot provide assurance that new supply additions will not outpace the level of future demand growth, thereby contributing to negative pressure on methanol price.

We are vulnerable to reductions in the availability of supply and fluctuations in the cost of natural gas.

Natural gas is the principal feedstock for producing methanol and it accounts for a significant portion of our operating costs. Accordingly, our results from operations depend in large part on the availability and security of supply and the price of natural gas. If, for any reason, we are unable to obtain sufficient natural gas for any of our plants on commercially acceptable terms or we experience interruptions in the supply of contracted natural gas, we could be forced to curtail production or close such plants, which could have an adverse effect on our results of operations and financial condition.

New Zealand

We have three plants in New Zealand with a total production capacity of up to 2.4 million tonnes of methanol per year, depending on natural gas composition. Two plants are located at Motunui and the third is located at nearby Waitara Valley. We have entered into several agreements with various natural gas suppliers to underpin our New Zealand operations with terms that range in length up to 2029. All agreements in New Zealand are take-or-pay agreements and include U.S. dollar base and variable price components where the variable price component is adjusted by a formula related to methanol prices above a certain level. We believe this pricing relationship enables these facilities to be competitive at all points in the methanol price cycle and provides gas suppliers with attractive returns. Certain of these contracts require the supplier to deliver a minimum amount of natural gas with additional volume dependent on the success of exploring and developing the related natural gas field.

We continue to pursue opportunities to contract additional natural gas to supply our plants in New Zealand.

9

The future operation of our New Zealand facilities depends on the ability of our contracted suppliers to meet their commitments and the success of ongoing exploration and development activities in the region. We cannot provide assurance that our contracted suppliers will be able to meet their commitments or that their ongoing exploration and development activities in New Zealand will be successful to enable our operations to operate at capacity. We cannot provide assurance that we will be able to obtain natural gas at economic terms or with the optimal carbon dioxide (“CO2”) composition. These factors could have an adverse impact on our results of operations and financial condition.

United States

We currently have two plants in Geismar, Louisiana with a total production capacity of 2.0 million tonnes. The Geismar facilities commenced first methanol production in 2015. We have recently reached a final investment decision to construct a 1.8 million tonne methanol plant in Geismar, Louisiana adjacent to our existing Geismar 1 and Geismar 2 facilities, which is expected to start production in the second half of 2022.

We have a fixed price agreement for the supply of substantially all of the natural gas requirements for the Geismar 1 facility that expires in 2025. We have forward contracts to hedge approximately 40% of the natural gas prices for the Geismar 2 facility through 2025. Additionally, we have a fixed price agreement for the supply of approximately one-third of the Geismar 3 facility’s expected annual natural gas requirements from 2023 to 2032. Natural gas received is fungible across the Geismar facilities. Further natural gas requirements at Geismar are expected to be either contracted at future dates or purchased in the spot market.

We believe that the long-term natural gas dynamics in North America will support the long-term operations of these facilities; however, we cannot provide assurance that our contracted suppliers will be able to meet their commitments or that we will be able to secure additional natural gas on commercially acceptable terms and this could have an adverse impact on our results of operations and financial condition.

Trinidad

Natural gas for our two methanol production facilities in Trinidad, with our share of total production capacity being 2.0 million tonnes per year, is supplied under take-or-pay contracts with the National Gas Company of Trinidad and Tobago Limited (“NGC”), which purchases the natural gas from upstream gas producers. Gas paid for, but not taken, in any year may be received in subsequent years subject to certain limitations. The contracts for Titan and Atlas have U.S. dollar base and variable price components, where the variable portion is adjusted by a formula related to methanol prices above a certain level. The contract for Atlas expires in 2024 and the contract for Titan expires at the end of 2019. We are currently in discussions with NGC to extend the Titan gas contract.

Large industrial consumers in Trinidad, including our Titan and Atlas facilities, have experienced curtailments of natural gas supply in the past due to a mismatch between upstream supply to NGC and downstream demand from NGC’s customers. While we believe the supply and demand fundamentals for natural gas in Trinidad will support the continued operation of these facilities, we cannot provide assurance that we will be able to renew gas contracts at economic terms. Additionally, we cannot provide assurance that our contracted gas suppliers will be able to fully meet their commitments, that we will not experience longer or greater than anticipated curtailments due to upstream outages or other issues in Trinidad and that these curtailments will not be material. These factors could have an adverse impact on our results of operations and financial condition.

Chile

Natural gas for our two plants in Chile is supplied by various producers in Chile and Argentina. A portion of the contracted gas is subject to deliver or pay and take or pay provisions. We believe that our current gas agreements will allow for a two-plant operation in Chile during the southern hemisphere summer months and up

10

to a maximum of 75% of a two-plant operation annually in the near-term. The price paid for natural gas is a mix of both fixed price and a U.S. dollar base price plus a variable price component that is adjusted by a formula related to methanol prices above a certain level.

Our primary Chilean natural gas supplier is Empresa Nacional del Petróleo (“ENAP”). ENAP has made significant investments in the development of natural gas from unconventional reservoirs and this effort has resulted in increased gas deliveries from ENAP to our facilities. In January 2016, the U.S. Geological Survey assessed a technically recoverable mean resource of 8.3 trillion cubic feet of unconventional tight gas in the Chilean Magallanes Province. However, the potential for a sustained increase in gas deliveries to our plants depends on the economics of the development of gas discoveries and, ultimately, the price at which we can obtain gas.

During 2018, we received natural gas from Argentina under a tolling arrangement whereby the natural gas received was converted into methanol and then re-delivered to Argentina. This tolling arrangement has now expired. In September 2018, we started receiving natural gas from Argentina under four new gas supply agreements. In January 2019, we re-commenced receiving natural gas under a fifth gas supply agreement with an Argentine supplier. We are continuing to work with gas suppliers in Chile and Argentina to secure sufficient natural gas to sustain our Chile operations into the future.

The future of our Chile operations is primarily dependent on the level of exploration and development of natural gas in southern Chile and our ability to secure a sustainable natural gas supply to our facilities on economic terms from Chile and Argentina. We cannot provide assurance that we will be able to continue to secure a sustainable natural gas supply to our facilities on economic terms and that this will not have an adverse impact on our results of operations or financial condition.

Egypt

We have a 25-year, take-or-pay natural gas supply agreement expiring in 2036 for the 1.26 million tonne per year methanol plant in Egypt in which we have a 50% equity interest. The price paid for gas is based on a U.S. dollar base price plus a variable price component that is adjusted by a formula related to methanol prices above a certain level. Under the contract, the gas supplier is obligated to supply, and we are obliged to take or pay for, a specified annual quantity of natural gas. Gas paid for, but not taken, in any year may be received in subsequent years subject to limitations. In addition, the natural gas supply agreement has a mechanism whereby we are partially compensated when gas delivery shortfalls in excess of a certain threshold occur. Natural gas is supplied to this facility from the same gas delivery grid infrastructure that supplies other industrial users in Egypt, as well as the general Egyptian population.

Since the plant commenced operations in 2011, Egypt has experienced periods of significant social unrest, including acts of sabotage and government transitions. We believe that these factors previously contributed to constraints in the development of new supplies of natural gas coming to market resulting in our Egypt plant operating below full capacity before late-2016.

In spite of positive developments more recently in the natural gas supply in Egypt, the restrictions experienced in past years may persist in the future. We cannot provide assurance that we will not experience natural gas restrictions and that this would not have an adverse impact on our results of operations and financial condition.

Canada

We have entered into fixed price contracts to supply substantially all of our natural gas requirements for our Medicine Hat facility through 2031. In addition to hedges in place through 2022, we have a long-term, fixed price physical supply contract with a progressively growing supply commitment that started in 2018 and increases to 80-90% of the plant’s natural gas requirements from 2023 through 2031.

11

We cannot provide assurance that our contracted suppliers will be able to meet their commitments or that we will be able to continue to secure sufficient natural gas for our Medicine Hat facility on commercially acceptable terms and that this will not have an adverse impact on our results of operations and financial condition.

Changing global economic conditions could negatively impact our business.

In addition to the potential influence of global economic activity levels on methanol demand and price, changing global economic conditions can result in changes in capital markets. A deterioration in economic conditions could have a negative impact on our investments, diminish our ability to access existing or future credit and increase the risk of defaults by customers, suppliers, insurers and other counterparties.

We are subject to risks inherent in foreign operations.

A significant portion of our operations and investments are located outside of North America, in New Zealand, Trinidad, Egypt, Chile, Europe and Asia. We are subject to risks inherent in foreign operations such as loss of revenue, property and equipment as a result of expropriation; import or export restrictions; anti-dumping measures; nationalization, war, insurrection, civil unrest, sabotage, terrorism and other political risks; increases in duties, taxes and governmental royalties; renegotiation of contracts with governmental entities; as well as changes in laws or policies or other actions by governments that may adversely affect our operations, including lack of certainty with respect to foreign legal systems, corruption and other factors inconsistent with the rule of law. Many of the foregoing risks related to foreign operations may also exist for our domestic operations in North America. The Company is committed to doing business in accordance with all applicable laws and its code of business conduct, but there is a risk that it, its subsidiaries or affiliated entities or their respective officers, directors, employees or agents could act in violation of its codes and applicable laws. Any such violation could severely damage our reputation and could result in substantial civil and criminal fines or penalties. Such damage to our reputation and fines and penalties could materially affect the Company’s business and have an adverse impact on our results of operations and financial condition.

Because we derive a significant portion of our revenues from production and sales by subsidiaries outside of Canada, the payment of dividends or the making of other cash payments or advances by these subsidiaries may be subject to restrictions or exchange controls on the transfer of funds in or out of the respective countries or result in the imposition of taxes on such payments or advances.

The dominant currency in which we conduct business is the United States dollar, which is also our reporting currency. The most significant components of our costs are natural gas feedstock and ocean-shipping costs and substantially all of these costs are incurred in United States dollars. Some of our underlying operating costs, capital expenditures and purchases of methanol, however, are incurred in currencies other than the United States dollar, principally the Canadian dollar, the Chilean peso, the Trinidad and Tobago dollar, the New Zealand dollar, the euro, the Egyptian pound and the Chinese yuan. We are exposed to increases in the value of these currencies that could have the effect of increasing the United States dollar equivalent of cost of sales, operating expenses and capital expenditures. A portion of our revenue is earned in euros, Canadian dollars and Chinese yuan. We are exposed to declines in the value of these currencies compared to the United States dollar, which could have the effect of decreasing the United States dollar equivalent of our revenue.

Trade in methanol is subject to duty in a number of jurisdictions. Methanol sold in certain markets from our producing regions is currently subject to import duties ranging from 0% to 5.5%. As well, the 10% tariff enacted in 2018 on methanol imported from the United States to China and from China to the United States has been increased to 25% in 2019. There can be no assurance that the duties will not increase, that duties will not be levied in other jurisdictions in the future or that we will be able to mitigate the impact of future duties, if levied, or that future duties will not have a significant negative effect.

12

Methanol is a globally traded commodity that is produced by many producers at facilities located around the world. Some producers and marketers may have direct or indirect contacts with countries that may, from time to time, be subject to international trade sanctions or other similar prohibitions (“Sanctioned Countries”). In addition to the methanol we produce, we purchase methanol from third parties under purchase contracts or on the spot market in order to meet our commitments to customers, and we also engage in product exchanges with other producers and marketers. We believe that we are in compliance with all applicable laws with respect to sales and purchases of methanol and product exchanges. However, as a result of the participation of Sanctioned Countries in our industry, we cannot provide assurance that we will not be exposed to reputational or other risks that could have an adverse impact on our results of operations and financial condition.

We are subject to risk associated with changes to tax laws.

The Company is subject to taxes, duties, levies, governmental royalties and other government-imposed compliance costs in numerous jurisdictions. New taxes and/or increases to the rates at which these amounts are determined could have an adverse impact on our results of operations and financial condition.

We have organized our operations in part based on certain assumptions about various tax laws (including capital gains, withholding taxes and transfer pricing), foreign currency exchange and capital repatriation laws and other relevant laws of a variety of foreign jurisdictions. While we believe that such assumptions are reasonable, we cannot provide assurance that foreign taxation or other authorities will reach the same conclusion. The results of audit of prior tax filings and the final determination of these events may have a material impact on the Company. Refer to other risk factors below for more information related to current legal matters. Further, if such foreign jurisdictions were to change or modify such laws, we could suffer adverse tax and financial consequences.

Restrictions in our current debt agreements or the solvency of financial institutions could affect our ability to access existing financing or obtain new financing.

We have recently secured an $800 million construction credit facility for the Geismar 3 Project and renewed our undrawn $300 million revolving credit facility with a syndicate of banks that will expire in July 2024. Our ability to maintain access to the facilities is subject to meeting certain financial covenants, including an EBITDA to interest coverage ratio and a debt to capitalization ratio, both ratios calculated in accordance with definitions in the credit agreement that include adjustments related to the Company’s limited recourse subsidiaries.

As at June 30, 2019, our long-term debt obligations include $1,200 million in unsecured notes, $92 million related to the Egypt limited recourse debt facilities (100% basis) and $167 million of other limited recourse debt (100% basis) related to the financing of ocean going vessels which we own through less than wholly-owned entities. We intend to refinance the $350 million of the unsecured notes due December 15, 2019. The covenants governing the unsecured notes, which are specified in an indenture, apply to the Company and its subsidiaries, excluding the Egypt entity and other limited recourse entities, and include restrictions on liens, sale and lease-back transactions, a merger or consolidation with another corporation or a sale of all or substantially all of the Company’s assets. The indenture also contains customary default provisions. The Egypt limited recourse debt facilities are described as limited recourse as they are secured only by the assets of the Egypt entity. Accordingly, the lenders to the limited recourse debt facilities have no recourse to the Company or its other subsidiaries. The Egypt limited recourse debt facilities have covenants and default provisions that apply only to the Egypt entity, including restrictions on the incurrence of additional indebtedness and a requirement to fulfill certain conditions before the payment of cash or other distributions.

We cannot provide assurance that we will be able to access new financing in the future on commercially acceptable terms or at all, or that the financial institutions providing the credit facility will have the ability to honour future draws. Additionally, failure to comply with any of the covenants or default provisions of the long-term debt facilities described above could result in a default under the applicable credit agreement that would

13

allow the lenders to not fund future loan requests, accelerate the due date of the principal and accrued interest on any outstanding loans or restrict the payment of cash or other distributions. Any of these factors could have a significant negative effect on our results of operations, our ability to pursue and complete strategic initiatives or on our financial condition.

We are vulnerable to credit risk of our customers.

Our customers are large global or regional petrochemical manufacturers or distributors and a number are highly leveraged. We monitor our customers’ financial status closely; however, some customers may not have the financial ability to pay for methanol in the future and this could have an adverse effect on our results from operations and financial condition.

Our business is subject to many operational risks for which we may not be adequately insured.

Production Risks

Most of our earnings are derived from the sale of methanol produced at our plants. Our business is subject to the risks of operating methanol production facilities, such as equipment breakdowns, interruptions in the supply of natural gas and other feedstocks, power failures, longer-than-anticipated planned maintenance activities, loss of port facilities, natural disasters or any other event, including unanticipated events beyond our control, that could result in a prolonged shutdown of any of our plants or impede our ability to deliver methanol to customers. In 2019, the Egypt plant experienced a high-pressure steam release which has resulted in a plant shut-down since April 9, 2019. The plant remains off-line while inspections and repairs are being performed. We anticipate the plant restarting in the second half of 2019. A prolonged plant shutdown at any of our major facilities could have an adverse effect on our results of operations and financial condition.

Joint Arrangement Risk

Certain of our assets are jointly held and are governed by partnership and shareholder agreements. As a result, certain decisions regarding these assets require a simple majority, while others require 100 percent approval of the owners. In addition, certain of these assets (ocean going vessels) are operated by unrelated third-party entities. The operating results of these assets is to some extent dependent on the effectiveness of the business relationship and decision making among the Company and the other joint owner(s) and the expertise and ability of these third-party operators to successfully operate and maintain the assets. While the Company believes that there are prudent governance and contractual rights in place, there can be no assurance that the Company will not encounter disputes with partners. Such events could impact operations or cash flows of these assets which, in turn, could have an adverse effect on our results of operations and financial condition.

Purchased Product Price Risk

In addition to the sale of methanol produced at our plants, we also purchase methanol produced by others on the spot market and through purchase contracts to meet our customer commitments and support our marketing efforts. We have adopted the first-in, first-out method of accounting for inventories and it generally takes between 30 and 60 days to sell the methanol we purchase. Consequently, we have the risk of holding losses on the resale of this product to the extent that methanol prices decrease from the date of purchase to the date of sale. Holding losses, if any, on the resale of purchased methanol could have an adverse effect on our results of operations and financial condition.

Distribution Risks

Excess capacity within our fleet of ocean vessels resulting from a prolonged plant shutdown or other event could have an adverse effect on our results of operations and financial condition as our vessel fleet is subject to

14

fixed time charter costs. In the event we have excess shipping capacity, we may be able to mitigate some of the excess costs by entering into sub-charters or third-party backhaul arrangements, although the success of this mitigation is dependent on conditions within the broader global shipping industry. If we suffer any disruptions in our distribution system and are unable to mitigate these costs, this could have an adverse effect on our results from operations and financial condition.

Insurance Risks

Although we maintain operational and construction insurance, including business interruption insurance, we cannot provide assurance that we will not incur losses beyond the limits of, or outside the coverage of, such insurance or that insurers will be financially capable of honouring future claims. From time to time, various types of insurance for companies in the chemical and petrochemical industries have not been available on commercially acceptable terms or, in some cases, have been unavailable. We cannot provide assurance that in the future we will be able to maintain existing coverage or that premiums will not increase substantially.

We may not be able to successfully identify, develop and complete new capital projects.

As part of our strategy to strengthen our position as the global leader in the production and marketing of methanol, we intend to continue pursuing new opportunities to enhance our strategic position in the methanol industry. Our ability to successfully identify, develop and complete new capital projects, including the Geismar 3 Project, is subject to a number of risks, including finding and selecting favourable locations for new facilities where sufficient natural gas and other feedstock is available with acceptable commercial terms, obtaining project or other financing on satisfactory terms, constructing and completing the projects within the contemplated budgets and schedules and other risks commonly associated with the design, construction and start-up of large complex industrial projects. We cannot provide assurance that we will be able to identify or develop new methanol projects.

Prospective impact of climate change could negatively impact our business.

Climate change poses a number of potential risks and impacts to the Company which remain uncertain today; however these potential risks and impacts may increase over time. The prospective impact of climate change may have an adverse impact on our operations, our suppliers or customers and thus impact the Company. The impacts of climate change may include water shortages, changing sea levels, changing storm patterns and intensities, and changing temperature levels, and the impact of these changes could be severe. We cannot predict the prospective impact of climate change on our operations, suppliers or customers, which could have an adverse impact on our results of operations and financial condition.

Government regulations relating to the protection of the environment could increase our costs of doing business.

The countries in which we operate and international and jurisdictional waters in which our vessels operate have laws, regulations, treaties and conventions in force to which we are subject, governing the environment and the management of natural resources as well as the handling, storage, transportation and disposal of hazardous or waste materials. We are also subject to laws and regulations governing emissions and the import, export, use, discharge, storage, disposal and transportation of toxic substances. The products we use and produce are subject to regulation under various health, safety and environmental laws. Non-compliance with these laws and regulations may give rise to compliance orders, fines, injunctions, civil liability and criminal sanctions.

Laws and regulations with respect to climate change and protecting the environment have become more stringent in recent years and may, in certain circumstances, impose absolute liability rendering a person liable for environmental damage without regard to negligence or fault on the part of such person. Such laws and regulations may also expose us to liability for the conduct of, or conditions caused by others or for our own acts

15

even if we complied with applicable laws at the time such acts were performed. To date, environmental laws and regulations have not had a significant adverse effect on our capital expenditures, earnings or competitive position. However, operating petrochemical manufacturing plants and distributing methanol exposes us to risks in connection with compliance with such laws and we cannot provide assurance that we will not incur significant costs or liabilities in the future.

Management of Emissions

CO2 is a by-product of the methanol production process. The amount of CO2 generated by the methanol production process depends on the production technology, plant age, feedstock and any export of the by-product hydrogen. CO2 emissions are also generated from our marine operations when fuel is consumed during the global transport of methanol. We monitor and manage our CO2 emissions intensity, defined as the quantity of CO2 released per unit of production or transported tonne, relating to both methanol production and marine operations. Plant efficiency, and thus CO2 emissions, is highly dependent on the design and reliability of the methanol plant, and accordingly the CO2 emission figure may vary from year to year depending on the mix of production assets and vessels in operation.

Under the United Nations Framework Convention on Climate Change through the Kyoto Protocol and more recently the Paris Agreement (in effect from 2020), many of the countries we operate in have agreed to put forth efforts to reduce greenhouse gas (GHG) emissions.

We are currently subject to GHG regulations in New Zealand, Canada and Chile, but our production in the United States, Trinidad and Egypt are not subject to such regulations.

In New Zealand, an Emissions Trading Scheme (“ETS”) imposes a carbon price on producers of fossil fuels, including natural gas, which is passed on to the Company, increasing the cost of gas that the Company purchases in New Zealand. However, as a trade-exposed company, the Company is entitled to a free allocation of emissions units to partially offset those increased costs. In 2018, the New Zealand government initiated a series of policy reviews that could impact the price of carbon in New Zealand and began consultations on proposed changes to the ETS that could impact our entitlements to free allocations. The changes that have been announced to date are anticipated to be enacted in 2019 with implementation expected by 2022. We cannot provide assurance that unanticipated changes to the ETS will not have a material impact on our business in the future.

Our Medicine Hat facility is in the Canadian province of Alberta, which implemented a new GHG reduction regulation in 2018. The Carbon Competitiveness Incentive Regulation (“CCIR”) established a benchmark emission intensity for GHG emissions from methanol production. To address the concerns of industries determined to be energy intensive and trade exposed, this benchmark provides an 80% free emission allocation based on three baseline years of data from our Medicine Hat facility. The regulation also gives a full 1:1 credit for the injection of CO2 into our methanol production process. In April 2019, a new provincial government was elected in Alberta. The new government has committed to replacing the CCIR with a Technology Innovation and Emissions Reduction program, to take effect in 2020. We cannot provide assurance that legislation and governmental changes will not have a material impact on our business in the future.

Chile has imposed a carbon tax of $5/tonne since 2017 on certain CO2 emissions. However, the cost could increase significantly if the rate per tonne of emissions or scope of the legislation changes, and as such we cannot provide assurance that legislation changes will not have a material impact on our business in the future.

Although we have formal and proactive compliance management systems in place, we cannot provide assurance over ongoing compliance with existing legislation or that future laws and regulations to which we are subject governing the environment and the management of natural resources as well as the handling, storage, transportation and disposal of hazardous or waste materials will not have an adverse effect on our results of operations and financial condition.

16

Perceived or untrue occurrences could affect our reputation and financial condition.

Damage to our reputation could result from the actual or perceived occurrence of any number of events, and could include any negative publicity (for example, with respect to our handling of environmental, health or safety matters), whether true or not. Although we believe that we conduct our operations in a prudent manner and that we take care in protecting our reputation, we do not ultimately have direct control over how we are perceived by others. Reputation loss may result in decreased investor confidence, an impediment to our overall ability to advance our projects or increased challenges in maintaining our social license to operate, which could have an adverse impact on our results of operations and financial condition.

Cyber security attacks and breaches, loss of data and other disruptions could compromise sensitive information related to our business which could adversely affect our business.

Our business processes rely on Information Technology (“IT”) systems that are interconnected with external networks, which increases the threat of cyber attack and the importance of cyber security. In particular, if a cyber attack was targeted at our production facilities or our ability to transport methanol, the result could harm our plants, people and our ability to meet customer commitments for a period of time. In addition, targeted attacks on our systems (or third parties that we rely on), failure of a key IT system or a breach in security measures designed to protect our IT systems could have an adverse impact on our results of operations, financial condition and reputation. We have previously been the subject of cyber attacks on our internal systems, but these incidents have not had a significant negative impact on our results of operations.

While we have a comprehensive program to protect our assets, detect an intrusion and respond in the event of a cyber security incident, such program may not be effective against all potential cyber security incidents. As the cyber threat landscape continues to evolve, we implement continuous mitigation efforts, including: cyber education for our staff, risk prioritized controls to protect against known and emerging threats; tools to provide automated monitoring and alerting; and backup and recovery systems to restore systems and return to normal operations; however, we cannot be certain that such efforts will be effective in protecting us from cyber security incidents. We may be required to commit additional resources to continue to modify or enhance our protective measures or to investigate and remediate any vulnerabilities to cyber attacks.

The Company collects, uses and stores sensitive data in the normal course of business, including intellectual property, proprietary business information and personal information of our employees and third parties. Despite our security measures in place, our IT systems may be vulnerable to cyber attacks or breaches. Any such breach could compromise information used or stored on our IT systems and/or networks and, as a result, the information could be accessed, publicly disclosed, lost or stolen. Any such access, disclosure or other loss of information could result in legal claims or proceedings, liability under laws that protect the privacy of personal information, regulatory penalties or other negative consequences, including disruption to our operations and damage to the Company’s reputation, which could have an adverse impact on our results of operations and financial condition.

We may be subject to litigation from time to time and may also be involved in disputes with other parties in the future which could lead to litigation.

The Company is subject, from time to time, to litigation and may be involved in disputes with other parties in the future, which may result in litigation and claims under such litigation may be material. Various types of claims may be raised in these proceedings, including, but not limited to breach of contract, product liability, tax, employment matters, breach or unauthorized access to the Company’s information technology and infrastructure, environmental damage, climate change and the impact thereof, antitrust, bribery, and other forms of corruption. The Company cannot predict the outcome of any litigation. Defense and settlement costs may be substantial, even with respect to claims that have no merit. If the Company cannot resolve these disputes favourably, its business, financial condition, results of operations and future prospects may be materially adversely affected.

Trinidad

The Board of Inland Revenue of Trinidad and Tobago has audited and issued assessments against our 63.1% owned joint venture, Atlas, in respect of the 2005 to 2012 financial years. All subsequent tax years remain open to assessment. The assessments relate to the pricing arrangements of certain long-term fixed-price sales contracts with affiliates that commenced in 2005 and continue through 2019. The long-term fixed-price sales contracts with affiliates were established as part of the formation of Atlas and management believes were reflective of market considerations at that time. Atlas had partial relief from corporation income tax until late July 2014.

During the periods under assessment and continuing through 2014, approximately 50% of Atlas produced methanol was sold under these fixed-price contracts. From late 2014 through 2019 fixed-prices sales represent approximately 10% of Atlas produced methanol.

Management believes it is impractical to disclose a reasonable estimate of the potential contingent liability due to the wide range of assumptions and interpretations implicit in the assessments.

The Company has lodged objections to the assessments. Although there can be no assurance that these tax assessments will not have a material adverse impact, based on the merits of the cases and advice from legal counsel, we believe our position should be sustained, that Atlas has filed its tax returns and paid applicable taxes in compliance with Trinidadian tax law, and as such has not accrued for any amounts relating to these assessments. Contingencies inherently involve the exercise of significant judgment, and as such the outcomes of these assessments and the financial impact to the Company could be material.

We anticipate the resolution of this matter in the court system to be lengthy and, at this time, cannot predict a date as to when we expect this matter to be resolved.

There can be no assurance as to the liquidity of the trading market for the Offered Debt Securities or that a trading market for the Offered Debt Securities will develop.

There is no public market for the Offered Debt Securities and, unless otherwise specified in the applicable prospectus supplement, we do not intend to apply for listing of the Offered Debt Securities on any securities exchanges. There can be no assurance as to the liquidity of the trading market for the Offered Debt Securities or that a trading market for the Offered Debt Securities will develop. If an active market for any Offered Debt Securities issued under this Prospectus does not develop, it could have an adverse effect on the market price of the Offered Debt Securities or your ability to sell the Offered Debt Securities.

Credit ratings may not reflect all risks of an investment in the Offered Debt Securities and may change.

Credit ratings may not reflect all risks associated with an investment in the Offered Debt Securities. Any credit ratings applied to the Offered Debt Securities are an assessment of our ability to pay our obligations. Consequently, real or anticipated changes in such credit ratings will generally affect the market value of the Offered Debt Securities. In addition, such credit ratings may not reflect the potential impact of the risks related to our business discussed or incorporated by reference in this Prospectus or in any prospectus supplement. There is no assurance that any credit rating assigned to the Offered Debt Securities will remain in effect for any given period of time or that any rating will not be lowered or withdrawn entirely by the relevant rating agency.

Changes in interest rates may cause the value of the Offered Debt Securities to decline.

Prevailing interest rates will affect the market price or value of the Offered Debt Securities. The market price or value of the Offered Debt Securities may decline as prevailing interest rates for comparable debt instruments rise, and increase as prevailing interest rates for comparable debt instruments decline.

18

The Offered Debt Securities will be effectively subordinated to certain indebtedness of our subsidiaries.

Unless otherwise provided with respect to a series of Offered Debt Securities, the Offered Debt Securities will be our unsubordinated and unsecured obligation and will rank equally with all of our other unsecured, unsubordinated obligations. We conduct a substantial portion of our business through our subsidiaries. Therefore, unless otherwise provided with respect to a series of Offered Debt Securities and unless guaranteed under the terms of the indenture governing the Offered Debt Securities, our obligations under the Offered Debt Securities will be structurally subordinate to all existing and future indebtedness and liabilities, including trade payables, of our subsidiaries.

19

USE OF PROCEEDS

Unless otherwise indicated in the applicable prospectus supplement, we will use the net proceeds from any sale of Offered Debt Securities for any one or more of debt repayment, working capital, capital expenditures related to plant construction and maintenance or other general corporate purposes. Pending such use of any proceeds, we may invest funds in short-term marketable securities.

EARNINGS COVERAGE

The following earnings coverage ratios have been prepared in accordance with Canadian securities law requirements and included in this Prospectus in accordance with Canadian disclosure requirements. They have been calculated on a consolidated basis using financial information prepared in accordance with IFRS for the year ended December 31, 2018, and the twelve-month period ended June 30, 2019, and give effect to all of our long-term financial liabilities, and the repayment, redemption or other retirement thereof since the respective dates indicated below. The ratios do not give pro forma effect to any offering of Offered Debt Securities offered by a prospectus supplement and this Prospectus or to any change in indebtedness subsequent to the dates indicated below. For purposes of these calculations, reported net earnings attributable to Methanex shareholders have been increased by interest expense and income taxes.

Period	Earnings Coverage Ratio(1)	Net earnings before interest expense and income taxes(2)
Year ended December 31, 2018	8.7 times	$	816.9 million
12-month period ended June 30, 2019	5.5 times	$	573.3 million

(1) The earnings coverage ratio is equal to net earnings attributable to Methanex shareholders, adjusted as described above, divided by interest expense. These ratios do not purport to be indicative of earnings coverage ratios for any future period.

(2) Effective January 1, 2019, we adopted IFRS 16, Leases (“IFRS 16”) with the cumulative effect of initial application recognized as an adjustment to retained earnings. Our 2018 results have not been restated. The most significant effect of IFRS 16 was the recognition of the initial present value of unavoidable lease payments as right of use assets and lease liabilities on the statement of financial position for leases that were previously accounted for as operating leases. For the six month period ended June 30, 2019, interest expense includes interest on lease liabilities due to adoption of IFRS 16.

DESCRIPTION OF DEBT SECURITIES

In this section, the words “Company”, “we”, “us”, “our” and “Methanex” refer only to Methanex Corporation and not to any of its subsidiaries or joint ventures. The following description sets forth certain general terms and provisions of the Offered Debt Securities. The particular terms and provisions of the series of Offered Debt Securities offered by a prospectus supplement and this Prospectus, and the extent to which the general terms and provisions described below may apply thereto, will be described in such prospectus supplement.

Unless otherwise specified in the applicable prospectus supplement, the Offered Debt Securities will be issued under the trust indenture, dated as of July 20, 1995, which was entered into between Methanex and The Bank of New York Mellon (formerly United States Trust Company of New York), as trustee (the “Trustee”), as currently supplemented (the trust indenture as supplemented and as will be supplemented is referred to herein as the “Indenture”). The Indenture is by its terms subject to and governed by the U.S. Trust Indenture Act of 1939, as amended. A copy of the form of Indenture has been filed with the SEC as an exhibit to the registration statement of which this Prospectus forms a part.

The summaries of the Indenture and the Offered Debt Securities are brief summaries of certain provisions of the Indenture and do not purport to be complete. For a more complete description, prospective investors should refer to the Indenture. Capitalized terms used in this section but not defined herein have the meaning ascribed thereto under the heading “Certain Definitions”. Whenever we refer to particular provisions of the Indenture, those provisions are qualified in their entirety by reference to the Indenture.

General

The Indenture does not limit the aggregate principal amount of debt securities (which may include debentures, notes, bonds or other evidences of indebtedness) which may be issued thereunder. It provides that debt securities may be issued from time to time in one or more series and may be denominated and payable in foreign currencies. The debt securities offered pursuant to this Prospectus will be limited to an aggregate principal amount (or the equivalent in other currencies) of US$1,200,000,000.

The terms of the debt securities we may offer may differ from the general information provided below. In particular, certain covenants described below may not apply to certain debt securities we may offer under the Indenture. We may issue debt securities with terms different from those of debt securities previously issued under the Indenture.

The applicable prospectus supplement will contain a description of the following terms relating to the debt securities being offered:

• the title of the Offered Debt Securities;

• any limit on the aggregate principal amount of the Offered Debt Securities;

• the extent and manner, if any, to which payment on or in respect of the Offered Debt Securities will be senior or will be subordinate to the prior payment of our other liabilities and obligations;

• the extent to which the Offered Debt Securities will be issued at a premium or a discount to the principal amount;

• the date or dates on which the Offered Debt Securities will mature and the portion (if less than all of the principal amount) of the Offered Debt Securities to be payable upon declaration of acceleration of maturity;

• the rate or rates per annum (which may be fixed or variable) at which the Offered Debt Securities will bear interest, if any, the date or dates from which any such interest will accrue (or the method by which such date or dates will be determined) and the dates on which any such interest will be payable and the regular record dates for any interest payable on the Offered Debt Securities;

21

• any mandatory or optional redemption or sinking fund or analogous provisions, including the period or periods within which, the price or prices at which and the terms and conditions upon which the Offered Debt Securities may be redeemed or purchased at the option of Methanex or otherwise;

• whether the Offered Debt Securities will be issuable in whole or in part in the form of one or more registered global securities (“Registered Global Securities”) and, if so, the identity of the depositary for such Registered Global Securities;

• the denominations in which debt securities will be issuable, if other than denominations of $1,000 and any integral multiple of $1,000 in excess thereof;

• each place where the principal of and any premium and interest on the Offered Debt Securities will be payable and each place where the Offered Debt Securities may be presented for registration of transfer or exchange;

• if other than U.S. dollars, the foreign currency or the units based on or relating to foreign currencies in which the Offered Debt Securities are denominated and/or in which the payment of the principal of and any premium and interest on the Offered Debt Securities will or may be payable;

• the terms and conditions, if any, on which the Offered Debt Securities may be convertible into or exchangeable for any other of our securities or securities of other entities;

• whether the payment of the Offered Debt Securities will be guaranteed by any other person, and the terms of any such guarantees;

• whether the Offered Debt Securities will have the benefit of any security interest created pursuant to the terms of the Indenture or otherwise; and

• any other terms of the Offered Debt Securities, including covenants and events of default which apply solely to the Offered Debt Securities, or any covenants or events of default generally applicable to the debt securities, which are not to apply to the Offered Debt Securities.

Our debt securities may be issued under the Indenture bearing no interest or interest at a rate below the prevailing market rate at the time of issuance, to be offered and sold at a discount below their stated principal amount. The Canadian and United States federal income tax consequences and other special considerations applicable to any such discounted debt securities or other debt securities offered and sold at par which are treated as having been issued at a discount for Canadian and/or United States federal income tax purposes will be described in the prospectus supplement relating thereto.

The Offered Debt Securities will not include debt securities in respect of which an index, formula or other method may be used to determine payments of principal and/or interest, or securities convertible or exchangeable into such debt securities, in respect of which the payment of principal and/or interest may be determined, in whole or in part, by reference to one or more underlying interests.

Ranking and Other Indebtedness

Except as indicated herein or in the applicable prospectus supplement, the Offered Debt Securities will be unsecured obligations of the Company and will rank equally with all of our other unsecured and unsubordinated Indebtedness from time to time outstanding. The Offered Debt Securities will be effectively subordinated to all Indebtedness and other liabilities of our subsidiaries (other than any applicable guarantor, for so long as its guarantee remains in effect) and subordinated to all secured Indebtedness and other secured liabilities of the Company, any applicable guarantor and our subsidiaries to the extent of the assets securing such Indebtedness and other liabilities.

22

Certain Covenants

Set forth below are certain covenants contained in the Indenture:

Change of Control

Upon the occurrence of a Change of Control Triggering Event, we will be required to make an offer (a “Change of Control Offer”) to repurchase all or any part (equal to $1,000 or an integral multiple thereof) of each Holder’s Offered Debt Securities. In the Change of Control Offer, we will offer to purchase Offered Debt Securities for a purchase price in cash equal to 101% of the aggregate principal amount of the Offered Debt Securities repurchased plus accrued and unpaid interest, if any, on the Offered Debt Securities repurchased, to the date of purchase; provided, however, that interest payable on or prior to the date of purchase will be payable to the Holders of the Offered Debt Securities repurchased registered as such on the regular record date for such interest.

Within 30 days following the date upon which a Change of Control Triggering Event occurred, or at our option, prior to any Change of Control but after the public announcement of the pending Change of Control, we will be required to mail, by first class mail, a notice to each Holder of Offered Debt Securities describing the transaction or transactions that constitute the Change of Control Triggering Event and offering to repurchase Offered Debt Securities on the date (the “Change of Control Payment Date”) specified in the notice, which date shall be between 30 and 60 days of the mailing of the notice, other than as may be required by law, pursuant to the procedures required by the Indenture and described in such notice. The notice, if mailed prior to the date of consummation of the Change of Control, will state that the Change of Control Offer is conditioned on the Change of Control being consummated on or prior to the Change of Control Payment Date.

We will comply with the requirements of Section 14(e) of and Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Offered Debt Securities as a result of a Change of Control Triggering Event. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control provisions of the Indenture, we will comply with the applicable securities laws and regulations and will not be deemed to have breached our obligations under the Change of Control provisions of the Indenture by virtue of such conflict.

Holders of Offered Debt Securities electing to have Offered Debt Securities purchased pursuant to a Change of Control Offer will be required to surrender their Offered Debt Securities with the form entitled “Option of Holder to Elect Purchase” on the reverse of the Offered Debt Securities completed to the paying agent at the address specified in the notice, or transfer their Offered Debt Securities to the paying agent by book-entry transfer pursuant to the applicable procedures of the paying agent, prior to the close of business on the third business day prior to the Change of Control Payment Date.

On the Change of Control Payment Date, we will be required, to the extent lawful, to (1) accept for payment all Offered Debt Securities or portions thereof properly tendered pursuant to the Change of Control Offer, (2) deposit with the paying agent an amount equal to the purchase price in respect of all Offered Debt Securities or portions thereof so tendered, and (3) deliver or cause to be delivered to the Trustee the Offered Debt Securities so accepted, together with an officers’ certificate stating the aggregate principal amount of Offered Debt Securities or portions thereof being purchased by us. The paying agent will be required to promptly mail to each Holder who properly tendered Offered Debt Securities, the purchase price for such Offered Debt Securities and the Trustee will be required to promptly authenticate and mail (or cause to be transferred by book-entry) to each such Holder a new Note equal in principal amount to any unpurchased portion of the Offered Debt Securities surrendered, if any; provided that each new Note will be in a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof.

The provisions described above that require us to make a Change of Control Offer following a Change of Control Triggering Event will be applicable whether or not any other provisions of the Indenture are applicable.

23

Holders will not be entitled to require us to purchase their Offered Debt Securities in the event of a takeover, recapitalization, leveraged buyout or similar transaction that is not a Change of Control. We may nonetheless incur significant additional indebtedness in connection with such a transaction.

We will not be required to make a Change of Control Offer upon a Change of Control Triggering Event if a third party makes such offer in the manner, at the times and otherwise in compliance with, the requirements set forth in the Indenture applicable to a Change of Control Offer made by us, and purchases all Offered Debt Securities properly tendered and not withdrawn under its offer.

Holders may not be able to require us to purchase their Offered Debt Securities in certain circumstances involving a significant change in the composition of our board of directors, including a proxy contest where our board of directors does not endorse the dissident slate of directors but approves them as Continuing Directors. In this regard, a decision of the Delaware Chancery Court (not involving us or our securities) considered a change of control redemption provision of an indenture governing publicly traded debt securities that is substantially similar to the change of control event described in clause (4) of the definition of “Change of Control.” In its decision, the court noted that a board of directors may “approve” a dissident shareholder’s nominees solely for purposes of such an indenture, provided the board of directors determines in good faith that the election of the dissident nominees would not be materially adverse to the interests of the corporation or its stockholders (without taking into consideration the interests of the holders of debt securities in making this determination).

The concept of Change of Control includes the direct or indirect sale, lease, transfer, conveyance or other disposition of “all or substantially all” of the properties or assets of us and our Restricted Subsidiaries taken as a whole. Although there is a limited body of case law interpreting the phrase “substantially all,” there is no precise established definition of the phrase under applicable law. Accordingly, the ability of a holder of Offered Debt Securities to require us to repurchase the Offered Debt Securities as a result of a sale, lease, transfer, conveyance or other disposition of less than all of the assets of us and our Subsidiaries taken as a whole to another Person or group may be uncertain.

There can be no assurance that we will have sufficient funds available at the time of any Change of Control Triggering Event, and consummate a Change of Control Offer for all Offered Debt Securities then outstanding, at a purchase price for 101% of their principal amount, plus accrued and unpaid interest to the Change of Control Payment Date. The terms of our other outstanding indebtedness also provide for repurchase rights upon a change in control under different terms. As a result, holders of our other indebtedness may have the ability to require us to repurchase their debt securities before the holders of the Offered Debt Securities offered hereby would have such repurchase rights. In addition, a Change of Control and certain other change of control events would constitute an event of default under our credit facility. As a result, we may not be able to make any of the required payments on, or repurchases of, the Offered Debt Securities without obtaining the consent of the lenders under our credit facility with respect to such payment or repurchase.

Limitation on Liens

We shall not, and shall not permit any Restricted Subsidiary to, Incur or to permit to exist any Lien of any nature whatsoever (other than Permitted Liens) on any of our or its property or assets now owned or hereafter acquired by us or it (including any Capital Stock or evidence of Indebtedness and including any of our Capital Stock or Indebtedness held by us or any Subsidiary) securing any Indebtedness, without contemporaneously therewith effectively securing the Offered Debt Securities equally and ratably with (or prior to) such Indebtedness for so long as such Indebtedness is so secured, unless, after giving effect to such Lien, the aggregate amount of all Indebtedness secured by such Liens (other than Permitted Liens) on our property or assets or that of our Restricted Subsidiaries, plus all of our Attributable Indebtedness and that of our Restricted Subsidiaries with respect to Sale/Leaseback Transactions permitted as described below under “– Limitation on Sale/Leaseback Transactions”, does not exceed 10% of our Consolidated Net Worth.

24

Limitation on Sale/Leaseback Transactions

We shall not, and shall not permit any Restricted Subsidiary to, enter into a Sale/Leaseback Transaction, unless, after giving effect thereto, the aggregate amount of all Attributable Indebtedness with respect to all such Sale/Leaseback Transactions, plus all Indebtedness secured by Liens to which the covenant described above under “– Limitations on Liens” is applicable, does not exceed 10% of Consolidated Net Worth. However, the provisions described in this “– Limitation on Sale/Leaseback Transactions” shall not apply to, and there shall be excluded from Attributable Indebtedness in any computation described in this covenant and in the covenant described above under “– Limitation on Liens”, Attributable Indebtedness with respect to a Sale/Leaseback Transaction if: (1) the lease in such Sale/Leaseback Transaction is for a period, including renewal rights, of three years or less; (2) we or a Restricted Subsidiary, within one year (or, in the event the net proceeds of the sale of the property leased pursuant to such Sale/Leaseback Transaction exceeds $75 million, within two years) after such Sale/Leaseback Transaction, apply an amount not less than the greater of the net proceeds of the sale of the property leased pursuant to such Sale/Leaseback Transaction or the fair market value of such property (as determined in good faith by the Board of Directors) to either the retirement of our or a Restricted Subsidiary’s Funded Indebtedness or the purchase by us or a Restricted Subsidiary of other property having a fair market value (as determined in good faith by the Board of Directors) at least equal to the fair market value of the property so leased in such Sale/Leaseback Transaction; or (3) such Sale/ Leaseback Transaction is entered into between us and a Restricted Subsidiary or between Restricted Subsidiaries.

Additional Guarantees; Limitation on Subsidiary Indebtedness

We shall not permit any Restricted Subsidiary to Incur any Indebtedness unless, at the time of such Incurrence such Restricted Subsidiary has Guaranteed all our obligations with respect to the Offered Debt Securities pursuant to the terms of the Indenture, such Guarantee to be in the form provided for in the Indenture. The foregoing shall not apply to: (1) any Indebtedness Incurred by a Restricted Subsidiary to finance its working capital requirements; provided, however, that the aggregate amount of such Indebtedness Incurred by all Restricted Subsidiaries who have not Guaranteed all the obligations of the Company with respect to the Offered Debt Securities pursuant to the terms of the Indenture and outstanding at any time shall not exceed $50 million; (2) any Indebtedness secured by (a) Permitted Liens or (b) Liens to which the exception in the covenant described above under “- Limitation on Liens” is applicable; provided, however, that the aggregate amount of all such Indebtedness and all our Indebtedness secured by such Liens (other than Permitted Liens), plus all of our and our Restricted Subsidiaries’ Attributable Indebtedness with respect to Sale/Leaseback Transactions permitted as described above under “- Limitation on Sale/Leaseback Transactions”, does not exceed 10% of Consolidated Net Worth; (3) any Attributable Indebtedness (a) with respect to a Sale/Leaseback Transaction which is permitted under the covenant described above under “- Limitation on Sale/Leaseback Transactions” or (b) to which the provisions described above under “- Limitation on Sale/Leaseback Transactions” are not applicable; and (4) any Indebtedness owed to and held by us or another Restricted Subsidiary, a shareholder of a Restricted Subsidiary or any affiliate of a shareholder of a Restricted Subsidiary; provided, however, that any subsequent transfer of any such Indebtedness or any subsequent transfer of any Capital Stock of such Restricted Subsidiary, or any other event, that results in such Restricted Subsidiary ceasing to be a Restricted Subsidiary shall be deemed to constitute the Incurrence of such Indebtedness at such time. Except if we have exercised either of the defeasance options described under “- Defeasance” below, no Guarantor shall be released from its Guarantee provided pursuant to this covenant or clause (1) in the second paragraph of “- Successor Company and Guarantors” below unless (1) such Guarantor ceases to be a Restricted Subsidiary or (2) such Guarantor has been discharged from all its obligations with respect to all Indebtedness Incurred by such Guarantor (other than such Guarantee and Indebtedness described in clause (4) in the immediately preceding sentence) and such Guarantor has not had any Indebtedness (other than such Guarantee and Indebtedness described in clause (4) in the immediately preceding sentence) outstanding for a period of 91 days.

25

Limitations on Affiliate Transactions and Unrestricted Subsidiaries

We shall not, and shall not permit any Restricted Subsidiary to, directly or indirectly, enter into or conduct any transaction (including, the purchase, sale, lease or exchange of any property or the rendering of any service) with any Unrestricted Subsidiary (an “Unrestricted Subsidiary Transaction”) on terms (1) that are less favorable in sum to us or such Restricted Subsidiary, as the case may be, than those that could be obtained at the time of such transaction in arm’s-length dealings with a person other than an Unrestricted Subsidiary or (2) that, in the event such Unrestricted Subsidiary Transaction involves an aggregate amount in excess of $25 million, are not in writing and have not been approved by a majority of the members of the Board of Directors. The foregoing shall not prohibit any Investment by us or any Restricted Subsidiary in any Unrestricted Subsidiary.

We shall not permit any Unrestricted Subsidiary to Incur any Indebtedness other than Non-Recourse Indebtedness; provided, however, that in the event any such Indebtedness ceases for any reason to constitute Non-Recourse Indebtedness, such Subsidiary shall be deemed to have Incurred such Indebtedness at such time.

We shall not, and shall not permit any Restricted Subsidiary to, directly or indirectly, transfer to any Unrestricted Subsidiary any property or assets owned by us or any Restricted Subsidiary on the date of the Indenture (1) on terms that are less favorable in sum to us or such Restricted Subsidiary, as the case may be, than those that could be obtained at the time of such transfer in arm’s-length dealings with a person other than an Unrestricted Subsidiary or (2) unless the aggregate price for such property or assets under such transfer, plus the aggregate prices for any other such property or assets under any other such transfers completed during the twelve month period immediately preceding such transfer, does not exceed $25 million.

Additional Amounts for Canadian Withholding Taxes

All payments made by us under or with respect to the Offered Debt Securities must be made free and clear of and without withholding or deduction for or on account of any present or future tax, duty, levy, impost, assessment or other governmental charge imposed or levied by or on behalf of the Government of Canada or of any province or territory thereof or by any authority or agency therein or thereof having power to tax (hereinafter “Taxes”), unless we are required to withhold or deduct Taxes by law or by the interpretation or administration thereof. If we are so required to withhold or deduct any amount for or on account of Taxes from any payment made under or with respect to the Offered Debt Securities, we will pay such additional amounts (“Additional Amounts”) as may be necessary so that the net amount received by each holder of the Offered Debt Securities (including Additional Amounts) after such withholding or deduction will not be less than the amount the holder of the Offered Debt Securities would have received if such Taxes had not been withheld or deducted (a similar indemnity will also be provided to holders of the Offered Debt Securities that are exempt from withholding but are required to pay Taxes directly on amounts otherwise subject to withholding); provided, however, that no Additional Amounts will be payable with respect to a payment made to a holder of the Offered Debt Securities (an “Excluded Holder”) (1) with which we do not deal at arm’s length (within the meaning of the Income Tax Act (Canada)) at the time of making such payment or (2) which is subject to such Taxes by reason of its being connected with Canada or any province or territory thereof otherwise than by the mere holding of Offered Debt Securities or the receipt of payments thereunder. We will also make such withholding or deduction and remit the full amount deducted or withheld to the relevant authority in accordance with applicable law.

We will furnish to holders of the Offered Debt Securities, within 30 days after the date the payment of any Taxes is due pursuant to applicable law, certified copies of tax receipts evidencing such payment by us. We will indemnify and hold harmless each holder of Offered Debt Securities (other than an Excluded Holder) and upon written request reimburse such holder of Offered Debt Securities for the amount of (1) any Taxes so levied or imposed and paid by such holder as a result of payments made under or with respect to the Offered Debt Securities, (2) any liability (including penalties, interest and expenses) arising therefrom or with respect thereto, and (3) any Taxes imposed with respect to any reimbursement under (1) or (2), but excluding any such Taxes on such holder’s net income.

26

At least 30 days prior to each date on which any payment under or with respect to the Offered Debt Securities is due and payable, if we are obligated to pay Additional Amounts with respect to such payment, we will deliver to the Trustee an officers’ certificate stating the fact that such Additional Amounts will be payable and the amount so payable and will set forth other information necessary to enable the Trustee to pay such Additional Amounts to holders of the Offered Debt Securities on the payment date. Whenever in the Indenture or in this Description of Debt Securities there is mentioned, in any context, the payment of principal, and premium (if any), redemption price, interest or any other amount payable under or with respect to any Offered Debt Security, such mention shall be deemed to include mention of the payment of Additional Amounts to the extent that, in the context, Additional Amounts are, were or would be payable in respect thereof.

Tax Redemption

The Offered Debt Securities may be redeemed, at our option, at any time in whole but not in part, on not less than 30 nor more than 60 days’ notice, at 100% of the aggregate principal amount thereof, plus accrued and unpaid interest (if any) to the date of redemption (subject to the right of holders of record on the relevant record date to receive interest due on the relevant interest payment date), in the event we have become or would become obligated to pay, on the next date on which any amount would be payable with respect to the Offered Debt Securities, any Additional Amounts as a result of a change in or an amendment to the laws (including any regulations promulgated thereunder) of Canada (or any political subdivision or taxing authority thereof or therein), or any change or amendment to any official position regarding the application or interpretation of such laws or regulations, which change or amendment is announced or becomes effective on or after the date of this prospectus.

Provision of Financial Information

We will provide to the Trustee, within 15 days after we file them with the SEC, copies, which may be in electronic format, of our annual report and of the information, documents and other reports (or copies of such portions of any of the foregoing as the SEC may by rules and regulations prescribe) which we are required to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act. Notwithstanding that we may not be required to remain subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act or otherwise report on an annual and quarterly basis on forms provided for such annual and quarterly reporting pursuant to rules and regulations promulgated by the SEC, we will continue to provide the Trustee:

• within 140 days after the end of each fiscal year, the information required to be contained in annual reports on Form 20-F, Form 40-F or Form 10-K as applicable (or any successor form); and

• within 60 days after the end of each of the first three fiscal quarters of each fiscal year, the information required to be contained in reports on Form 6-K (or any successor form) which, regardless of applicable requirements will, at a minimum, contain such information required to be provided in quarterly reports under the laws of Canada or any province thereof to security holders of a corporation with securities listed on the Toronto Stock Exchange, whether or not we have any of our securities listed on such exchange.

Notwithstanding the foregoing, we are not required to deliver to the Trustee any information which is posted on SEDAR, EDGAR or our website.

Successor Company and Guarantors

We may not amalgamate or consolidate with or merge with or into, or convey, transfer or lease, in one transaction or a series of transactions, all or substantially all our assets to, any person, unless: (1) the resulting, surviving or transferee person (if not us) is organized and existing under the federal laws of Canada or the laws of any province thereof or the laws of the United States of America, any State thereof or the District of Columbia and such person expressly assumes by a supplemental indenture, executed and delivered to the Trustee, in form

27

satisfactory to the Trustee, all of our obligations under the Indenture and the Offered Debt Securities; (2) immediately after giving effect to such transaction, no Default shall have occurred and be continuing; and (3) we deliver to the Trustee an officers’ certificate and an opinion of counsel (who may rely on such officers’ certificate as to matters of fact), each stating that such amalgamation, consolidation, merger, conveyance, transfer or lease and such supplemental indenture (if any) comply with the Indenture. The resulting, surviving or transferee person will be the successor company under the Indenture and the Offered Debt Securities.

We will not permit any Restricted Subsidiary that is a Guarantor to amalgamate or consolidate with or merge with or into, or convey, transfer or lease, in one transaction or a series of transactions, all or substantially all its assets to, any person unless: (1) the resulting, surviving or transferee person (if not such Guarantor) is organized and existing under the laws of the jurisdiction under which such Guarantor or its parent corporation was organized or under the federal laws of Canada or the laws of any province thereof or the laws of the United States of America, or any State thereof or the District of Columbia and such person expressly assumes by a supplemental indenture, executed and delivered to the Trustee, in form satisfactory to the Trustee, all the obligations of such Guarantor under its Guarantee unless such resulting, surviving or transferee person has been released from such Guarantee in accordance with the terms of the Indenture; (2) immediately after giving effect to such transaction, no Default shall have occurred and be continuing; and (3) we deliver to the Trustee an officers’ certificate and an opinion of counsel (who may rely on such officers’ certificate as to matters of fact), each stating that such amalgamation, consolidation, merger, conveyance, transfer or lease and such supplemental indenture (if any) comply with the Indenture.

Events of Default

An “Event of Default” with respect to the Offered Debt Securities is defined in the Indenture as (1) a default by us in the payment of interest on the Offered Debt Securities (including any Additional Amount) when due and payable, continued for 30 days, (2) a default by us in the payment of principal with respect to the Offered Debt Securities when due and payable at Stated Maturity, upon redemption, upon declaration or otherwise, (3) the failure by us or a Guarantor to comply with the obligations described under “– Certain Covenants – Change of Control” or “– Successor Company and Guarantors” above, (4) the failure by us or any Restricted Subsidiary for 60 days after notice to comply with any of the obligations described under “– Certain Covenants” above other than “ – Certain Covenants – Change of Control”, (5) the failure by us or any Restricted Subsidiary for 60 days after notice to comply with the agreements contained in the Indenture or the Offered Debt Securities (other than a failure described in (1), (2), (3) or (4) above or a failure to comply with any of our or its obligations under the covenants or agreements that are specifically for the benefit of one or more series of debt securities issued pursuant to the Indenture other than the Offered Debt Securities), (6) Indebtedness of us or any Restricted Subsidiary is not paid within any applicable grace period and is accelerated by the holders thereof, or is accelerated by the holders thereof because of a default, and the total amount of such Indebtedness unpaid, or due and payable, and accelerated exceeds $50 million (the “cross acceleration provision”), (7) certain specified events of bankruptcy, insolvency or reorganization of us or a Significant Subsidiary (the “bankruptcy default provision”) or (8) any Guarantee of the Offered Debt Securities by any Guarantor at any time ceases to be in full force and effect for any reason (other than as a result of a release of such Guarantee in accordance with the terms of the Indenture) (the “guarantee default provision”). A default under clause (4) or (5) will not constitute an Event of Default until the Trustee or the holders of at least 25% in principal amount of the outstanding Offered Debt Securities notify us of the default and we do not cure such default within the time specified after receipt of such notice.

If an Event of Default (other than a bankruptcy default with respect to us) occurs and is continuing with respect to the Offered Debt Securities, the Trustee by notice to us, or the holders of at least 25% in principal amount of the Offered Debt Securities then outstanding by notice to us and the Trustee, may declare the principal of and accrued but unpaid interest on all the Offered Debt Securities to be due and payable. Upon such a declaration, such principal and interest shall be due and payable immediately. If a bankruptcy default with respect to us occurs, the principal of and interest on all the debt securities issued pursuant to the Indenture,

28

including the Offered Debt Securities, will ipso facto become and be immediately due and payable without any declaration or other act on the part of the Trustee or any holders of debt securities issued pursuant to the Indenture. Under certain circumstances, the holders of a majority in principal amount of the Offered Debt Securities may rescind any such acceleration with respect to the Offered Debt Securities and its consequences.

Subject to the provisions of the Indenture relating to the duties of the Trustee, in case an Event of Default occurs and is continuing, the Trustee will be under no obligation to exercise any of the rights or powers under the Indenture at the request or direction of any of the holders of the Offered Debt Securities then outstanding unless such holders have offered to the Trustee reasonable indemnity or security against any loss, liability or expense. Except to enforce the right to receive payment of principal, premium (if any) or interest when due, no holder of Offered Debt Securities may pursue any remedy with respect to the Indenture or the Offered Debt Securities unless (1) such holder has previously given the Trustee notice that an Event of Default is continuing, (2) holders of at least 25% in principal amount of the outstanding Offered Debt Securities have requested the Trustee to pursue the remedy, (3) such holders have offered the Trustee reasonable security or indemnity against any loss, liability or expense, (4) the Trustee has not complied with such request within 60 days after the receipt thereof and the offer of security or indemnity, and (5) the holders of a majority in principal amount of the Offered Debt Securities have not given the Trustee a direction inconsistent with such request within such 60-day period. Subject to certain restrictions, the holders of a majority in principal amount of the outstanding Offered Debt Securities may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee with respect to the Offered Debt Securities or of exercising any trust or power conferred on the Trustee with respect to the Offered Debt Securities. The Trustee, however, may refuse to follow any direction that conflicts with law or the Indenture or that the Trustee determines is unduly prejudicial to the rights of any other holder of the outstanding Debt Securities or that would involve the Trustee in personal liability.

Under the Indenture, if a Default occurs with respect to the Offered Debt Securities and is continuing and is known to the Trustee, the Trustee must mail to each holder of the Offered Debt Securities notice of the Default within 90 days after it occurs. Except in the case of a Default in the payment of principal of, premium (if any) or interest on the Offered Debt Securities, the Trustee may withhold notice if and so long as a committee of its trust officers determines in good faith that withholding notice is in the interest of the holders of Offered Debt Securities. In addition, we are required to deliver to the Trustee, within 120 days after the end of each fiscal year, a certificate indicating whether the signers thereof know of any Default that occurred during the previous year. We are also required to deliver to the Trustee, within 30 days after the occurrence thereof, written notice of any event which would constitute certain Defaults, their status and what action we are taking or propose to take with respect thereto.

Amendments and Waivers

Subject to certain exceptions, including those set out below, the Indenture may be amended with respect to the Debt Securities (including the Offered Debt Securities) with the consent of the holders of not less than a majority in principal amount of the outstanding Debt Securities and any past default or compliance with any provisions may be waived with such a consent of the holders of a majority in principal amount of the outstanding Debt Securities unless the amendment or waiver of past default or compliance is in respect of a provision which relates only to the Offered Debt Securities in which case such amendment or waiver may be effected with the consent of the holders of not less than a majority in principal amount of the Offered Debt Securities. However, without the consent of each holder of outstanding Offered Debt Securities, no amendment may, among other things, (1) reduce the amount of the Offered Debt Securities whose holders must consent to an amendment, (2) reduce the rate of or extend the time for payment of interest on any Offered Debt Securities, (3) reduce the principal of or extend the Stated Maturity of any Offered Debt Securities, (4) reduce the premium payable upon the redemption of any Offered Debt Securities or change the time at which any Offered Debt Securities may or shall be redeemed, (5) make any Offered Debt Securities payable in currency other than that stated in the Offered Debt Securities, (6) make any change to the provisions of the Indenture described under “ – Additional Amounts for Canadian Withholding Taxes” above that adversely affects the rights of any holder of the Offered Debt

Securities, (7) impair the rights of any holder of the Offered Debt Securities to receive payment of principal of and interest on such holder’s Offered Debt Securities (including any Additional Amount) on or after the due dates therefor or to institute suit for the enforcement of any payment on or with respect to such holder’s Offered Debt Securities, (8) make any change in the Guarantee of the Offered Debt Securities by any Guarantor that would adversely affect any holder of the Offered Debt Securities or (9) make any change in the amendment provisions which require each holder’s consent or in the provisions which limit suits by holders.

Without the consent of any holder of the Offered Debt Securities, we and the Trustee may amend the Indenture to cure any ambiguity, defect or inconsistency, to provide for the assumption by a successor corporation of our obligations or those of a Guarantor under the Indenture, to add Guarantees with respect to the Offered Debt Securities, to secure all or any of the Offered Debt Securities, to add to our covenants or to add Events of Default for the benefit of the holders of the Offered Debt Securities or to surrender any right or power conferred upon us, to make any change that does not adversely affect the rights of any holder of the Offered Debt Securities in any material respect, to establish the form or terms of the Offered Debt Securities, to supplement any of the provisions of the Indenture to the extent necessary to permit or facilitate the defeasance or discharge of the Offered Debt Securities that does not adversely affect the rights of any holders of the Offered Debt Securities in any material respect, to change or eliminate any provision of the Indenture that becomes effective only when there is not outstanding any debt security of any series issued under the Indenture which is entitled to the benefit of such provision or to comply with any requirement of the SEC in connection with the qualification of the Indenture under the Trust Indenture Act.

The consent of the holders of the Offered Debt Securities is not necessary under the Indenture to approve the particular form of any proposed amendment. It is sufficient if such consent approves the substance of the proposed amendment.

After an amendment under the Indenture becomes effective, we are required to mail to holders of the Offered Debt Securities a notice briefly describing such amendment. However, the failure to give such notice to all holders of the Offered Debt Securities, or any defect therein, will not impair or affect the validity of the amendment.

Defeasance

We at any time may terminate all our and each Guarantor’s obligations under the Offered Debt Securities and our obligations and those of each such Guarantor under the Indenture with respect to the Offered Debt Securities (“legal defeasance”), except for certain obligations, including those respecting the defeasance trust and obligations to register the transfer or exchange of the Offered Debt Securities, to replace mutilated, destroyed, lost or stolen Offered Debt Securities and to maintain a registrar and paying agent in respect of the Offered Debt Securities. We at any time may terminate our and each Guarantor’s obligations with respect to the Offered Debt Securities under the covenants described above under “Certain Covenants”, the operation of the cross acceleration provision, the bankruptcy default provision with respect to Significant Subsidiaries, the guarantee default provision and the limitations contained in the second paragraph of “Successor Company and Guarantors” above (“covenant defeasance”).

We may exercise our legal defeasance option notwithstanding our prior exercise of our covenant defeasance option. If we exercise our legal defeasance option with respect to the Offered Debt Securities, payment of the Offered Debt Securities may not be accelerated because of an Event of Default with respect thereto and each Guarantor will be released from its Guarantee with respect to the Offered Debt Securities. If we exercise our covenant defeasance option with respect to the Offered Debt Securities, payment of the Offered Debt Securities may not be accelerated because of an Event of Default specified in clause (3) (with respect to Guarantors only in respect of the obligations described under “– Successor Company and Guarantors”), (4), (5), (6), (7) (with respect to Significant Subsidiaries only), or (8) of the first paragraph under “Events of Default” above or because of our failure to comply with clause (2) in the first paragraph of “Successor Company and Guarantors” above and each Guarantor will be released from its Guarantee with respect to the Offered Debt Securities.

30

In order to exercise either defeasance option with respect to the Offered Debt Securities, we must irrevocably deposit in trust (the “defeasance trust”) with the Trustee money or U.S. Government Obligations for the full payment of principal, premium (if any) and interest on the Offered Debt Securities to redemption or maturity, as the case may be, and must comply with certain other conditions, including delivering to the Trustee: (1) an opinion of counsel in the United States to the effect that holders of the Offered Debt Securities will not recognize income, gain or loss for United States Federal income tax purposes as a result of such deposit and defeasance and will be subject to United States Federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such deposit and defeasance had not occurred (and, in the case of legal defeasance only, such opinion of counsel must be based on a ruling of the United States Internal Revenue Service or other change since the date of the original Indenture in applicable United States Federal income tax law); (2) an opinion of counsel in Canada to the effect that (A) holders of the Offered Debt Securities will not recognize income, gain or loss for Canadian federal or provincial income tax or other tax purposes as a result of such legal defeasance or covenant defeasance, as applicable, and will be subject to Canadian federal and provincial income tax and other tax on the same amounts, in the same manner and at the same times as would have been the case if such defeasance or covenant defeasance, as applicable, had not occurred, and (B) payments out of the defeasance trust will be free and exempt from any and all withholding and other income taxes of whatever nature of Canada or any province thereof or political subdivision thereof or therein having the power to tax (other than any municipality or similar political subdivision), except in the case of a payment made to a holder of the Offered Debt Securities (a) with which we do not deal at arm’s length (within the meaning of the Income Tax Act (Canada)) at the time of the making of such payment or (b) which is subject to such taxes by reason of its being connected with Canada or any province or territory thereof otherwise than by the mere holding of the Offered Debt Securities or the receipt of payments thereunder; (3) a certificate from a nationally recognized firm of independent accountants opining that the payments of principal and interest when due and without investment on the U.S. Government Obligations plus any deposited money without investment will provide cash at such times and in such amounts as will be sufficient to pay the principal, premium (if any) and interest when due on all the Offered Debt Securities to maturity or redemption, as the case may be; and (4) an opinion of counsel stating that the defeasance trust does not constitute, or is qualified as, a regulated investment company under the Investment Company Act of 1940, as amended. In addition, we can only exercise either type of defeasance if (1) during the 91 days that follow the establishment of the defeasance trust, no Default under the bankruptcy default provision occurs to us and is continuing at the end of the period, (2) no Default has occurred and is continuing on the date the defeasance trust is established after giving effect to the establishment of the defeasance trust, and (3) depositing funds into the defeasance trust does not constitute a default under any other of our binding agreements.

Book-Entry, Delivery and Form

The Offered Debt Securities of a particular series will be represented by one or more fully registered global securities without coupons (the “Global Debt Securities”) and will be deposited upon issuance with the Trustee as custodian for The Depository Trust Company (“DTC”), in New York, New York, and registered in the name of DTC or its nominee. Except as set forth below, the Global Debt Securities may be transferred in whole and not in part only to DTC or another nominee of DTC.

So long as DTC or its nominee is the registered owner thereof, DTC or such nominee, as the case may be, will be considered the sole owner or holder of the Offered Debt Securities represented by the Global Debt Securities for all purposes under the Indenture. Except as provided below, owners of beneficial interests in the Global Debt Securities will not be entitled to have the Offered Debt Securities represented by the Global Debt Securities registered in their names, will not receive or be entitled to receive physical delivery of the Offered Debt Securities in definitive form and will not be considered the owners or holders thereof under the Indenture.

The following is based on information furnished by DTC:

DTC is a limited-purpose trust company organized under the New York Banking Law, a “banking organization” within the meaning of the New York Banking Law, a member of the Federal Reserve System, a

31

“clearing corporation” within the meaning of the New York Uniform Commercial Code, and a “clearing agency” registered pursuant to the provisions of Section 17A of the Exchange Act. DTC holds securities that its participants (“Direct Participants”) deposit with DTC. DTC also facilitates the post-trade settlement among Direct Participants of sales and other securities transactions in deposited securities, through electronic computerized book-entry transfers and pledges between Direct Participants’ accounts. This eliminates the need for physical movement of securities certificates. Direct Participants include both U.S. and non-U.S. securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations. DTC is a wholly-owned subsidiary of The Depository Trust & Clearing Corporation (“DTCC”). DTCC is the holding company for DTC, National Securities Clearing Corporation and Fixed Income Clearing Corporation, all of which are registered clearing agencies, and DTCC is owned by the users of its regulated subsidiaries. Access to the DTC system is also available to others such as both U.S. and non-U.S. securities brokers and dealers, banks, trust companies, and clearing corporations that clear through or maintain a custodial relationship with a Direct Participant, either directly or indirectly (“Indirect Participants”). The DTC Rules applicable to its Participants are on file with the SEC.

Purchases of the Offered Debt Securities under the DTC system must be made by or through Direct Participants, which will receive a credit for such Offered Debt Securities on DTC’s records. The ownership interest of each actual purchaser of Offered Debt Securities represented by a Global Debt Security (“Beneficial Owner”) is in turn to be recorded on the Direct and Indirect Participants’ records. Beneficial Owners will not receive written confirmation from DTC of their purchase, but Beneficial Owners are expected to receive written confirmations providing details of the transaction, as well as periodic statements of their holdings, from the Direct or Indirect Participants through which such Beneficial Owner entered into the transaction. Transfers of ownership interests in the Global Debt Securities representing the Offered Debt Securities are to be accomplished by entries made on the books of Direct and Indirect Participants acting on behalf of Beneficial Owners. Beneficial Owners of the Global Debt Securities representing the Offered Debt Securities will not receive the Offered Debt Securities in definitive form representing their ownership interests therein, except in the event that use of the book-entry system for the Offered Debt Securities is discontinued or upon the occurrence of certain other events described herein.

To facilitate subsequent transfers, all Global Debt Securities representing the Offered Debt Securities deposited by Direct Participants with DTC are registered in the name of DTC’s partnership nominee, Cede & Co., or such other name as may be requested by an authorized representative of DTC. The deposit of Global Debt Securities representing the Offered Debt Securities with DTC and their registration in the name of Cede & Co. or such other DTC nominee do not effect any change in beneficial ownership. DTC has no knowledge of the actual Beneficial Owners of the Offered Debt Securities; DTC’s records reflect only the identity of the Direct Participants to whose accounts such Offered Debt Securities are credited, which may or may not be the Beneficial Owners. The Direct and Indirect Participants will remain responsible for keeping account of their holdings on behalf of their customers.

Conveyance of notices and other communications by DTC to Direct Participants, by Direct Participants to Indirect Participants, and by Direct Participants and Indirect Participants to Beneficial Owners will be governed by arrangements among them, subject to any statutory or regulatory requirements as may be in effect from time to time.

Principal, premium, if any, and interest payments on the Global Debt Securities representing the Offered Debt Securities will be made to Cede & Co., or such other nominee as may be requested by an authorized representative of DTC. DTC’s practice is to credit Direct Participants’ accounts upon DTC’s receipt of funds and corresponding information from us or the Trustee, on the applicable payment date in accordance with their respective holdings shown on DTC’s records. Payments by Participants to Beneficial Owners will be governed by standing instructions and customary practices, as is the case with securities held for the accounts of customers in bearer form or registered in “street name,” and will be the responsibility of such Participant and not of DTC, the Trustee or us, subject to any statutory or regulatory requirements as may be in effect from time to time. Payment of principal, premium, if any, and interest to Cede & Co. (or such other nominee as may be requested

32

by an authorized representative of DTC) is our responsibility or that of the Trustee, disbursement of such payments to Direct Participants will be the responsibility of DTC, and disbursement of such payments to the Beneficial Owners will be the responsibility of Direct and Indirect Participants. Neither we nor the Trustee will have any responsibility or liability for the disbursements of payments in respect of ownership interests in the Offered Debt Securities by DTC or the Direct or Indirect Participants or for maintaining or reviewing any records of DTC or the Direct or Indirect Participants relating to ownership interests in the Offered Debt Securities or the disbursements of payments in respect thereof.

DTC may discontinue providing its services as depository with respect to the Offered Debt Securities at any time by giving reasonable notice to us or the Trustee. Under such circumstances, in the event that a successor securities depository is not obtained, Offered Debt Securities in definitive form are required to be printed and delivered.

We may decide to discontinue use of the system of book-entry-only transfers through DTC (or a successor securities depository). In that event, Offered Debt Securities in definitive form will be printed and delivered to DTC.

The information in this section concerning DTC and DTC’s book-entry system has been obtained from sources that we believe to be reliable, but is subject to any changes to the arrangements between us and DTC and any changes to such procedures that may be instituted unilaterally by DTC.

Enforceability of Judgments

Since a substantial portion of our assets and those of our Subsidiaries are outside the United States, any judgment obtained in the United States against us or any of our Subsidiaries, including judgments with respect to the payment of principal, interest, Additional Amounts or redemption price with respect to the Offered Debt Securities, may not be collectible within the United States.

We have been informed by our Canadian counsel, McCarthy Tétrault LLP, that the laws of the Province of British Columbia and the federal laws of Canada applicable therein permit an action to be brought in a court of competent jurisdiction in the Province of British Columbia (a “British Columbia Court”) on any final and conclusive judgment in personam (i.e., against the person) of a Federal or state court in the State of New York (“New York Court”) against us that is subsisting and unsatisfied respecting the enforcement of the Offered Debt Securities or the Indenture, that is not impeachable as void or voidable under the laws of the State of New York and that is for a sum certain if (1) the New York Court that rendered such judgment had jurisdiction over the judgment debtor, as recognized by a British Columbia Court (and submission by us in the Offered Debt Securities or the Indenture to the jurisdiction of the New York Court will be deemed sufficient for this purpose); (2) proper service of process in respect of the proceeding in which such judgment was made in accordance with New York law; (3) such judgment was not obtained by fraud or in a manner contrary to natural justice, and the enforcement thereof would not be either inconsistent with public policy, as the term is applied by a British Columbia Court, or contrary to any order made by the Attorney General of Canada under the Foreign Extraterritorial Measures Act (Canada) or contrary to any order made by the Competition Tribunal under the Competition Act (Canada); (4) the enforcement of such judgment in British Columbia does not constitute, directly or indirectly, the enforcement of any laws of the State of New York or of the United States of America which a British Columbia Court would characterize as revenue, expropriatory, penal or public laws; (5) in an action to enforce a default judgment, the judgment does not contain a manifest error on its face; (6) the action to enforce such judgment is commenced within the applicable limitation period after the date of such judgment; and (7) the judgment does not conflict with another final and conclusive judgment in the same cause of action; provided that a British Columbia Court may stay an action to enforce a foreign judgment if an appeal of the judgment is pending or the time for appeal has not expired; and provided further that under the Currency Act (Canada), a British Columbia Court may only give judgment in Canadian dollars.

33

Consent to Jurisdiction and Service

The Indenture provides that we irrevocably designated and appointed CT Corporation System (and any successor entity), as our agent for service of process in any suit or proceeding arising out of or relating to the Indenture or the Offered Debt Securities for actions brought in any federal or state court located in the Borough of Manhattan in the City of New York and will submit to such jurisdiction.

Governing Law
