Trinseo PLC

Quarterly Report on Form 10-Q

For the quarterly period ended March 31, 2022

Unless otherwise indicated or required by context, as used in this Quarterly Report on Form 10-Q (“Quarterly Report”), the term “Trinseo” refers to Trinseo PLC (NYSE: TSE), a public limited company existing under the laws of Ireland, and not its subsidiaries. The terms “Company,” “we,” “us” and “our” refer to Trinseo and its consolidated subsidiaries, taken as a consolidated entity. Trinseo PLC is the surviving entity of a cross-border merger with our predecessor company, Trinseo S.A., which merger was approved by shareholders in June 2021 and completed in October 2021. All financial data provided in this Quarterly Report is the financial data of Trinseo PLC, unless otherwise indicated. Prior to the formation of the Company, our business was wholly owned by The Dow Chemical Company (together with other affiliates, “Dow”). The Company may distribute cash to shareholders under Irish law via dividends or distributions made out of distributable profits.

Definitions of capitalized terms not defined herein appear within our Annual Report on Form 10-K for the year ended December 31, 2021 (“Annual Report”) filed with the Securities and Exchange Commission (“SEC”) on February 23, 2022.

Cautionary Note on Forward-Looking Statements

This Quarterly Report contains, without limitation, statements concerning plans, objectives, goals, projections, forecasts, strategies, future events or performance, and underlying assumptions and other statements, which are not statements of historical facts. Forward-looking statements may be identified by the use of words like “expect,” “anticipate,” “intend,” “forecast,” ”estimate,” “see,” “outlook,” “will,” “may,” “might,” “potential,” “likely,” “target,” “plan,” “contemplate,” “seek,” “attempt,” “should,” “could,” “would,” or expressions of similar meaning. Forward-looking statements reflect management’s evaluation of information currently available and are based on our current expectations and assumptions regarding our business, the economy and other future conditions. Because forward-looking statements relate to the future, they are subject to inherent uncertainties, risks and changes in circumstances that are difficult to predict.

Specific factors that may impact performance or other predictions of future actions have, in many but not all cases, been identified in connection with specific forward-looking statements. Factors that might cause such a difference include, but are not limited to, our ability to complete the sale of our Styrenics business; our ability to successfully execute our transformation strategy and business strategy; our ability to integrate acquired businesses; global supply chain volatility, increased costs or disruption in the supply of raw materials or increased costs for transportation of our products; the European Commission request for information; the nature of investment opportunities presented to the Company from time to time; and those discussed in our Annual Report filed with the SEC on February 23, 2022 under Part I, Item IA— “Risk Factors,” within this Quarterly Report and in other filings and furnishings made by the Company with the SEC from time to time.

As a result of these or other factors, our actual results, performance or achievements may differ materially from those contemplated by the forward-looking statements. They are neither statements of historical fact nor guarantees or assurances of future performance. Therefore, we caution you against relying on these forward-looking statements. The forward-looking statements included in this Quarterly Report are made only as of the date hereof. We undertake no obligation to publicly update or revise any forward-looking statement as a result of new information, future events or otherwise, except as otherwise required by law.

Available Information

Our annual reports on Form 10-K, quarterly reports on Form 10-Q and current reports on Form 8-K, and amendments to those reports filed or furnished pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934, are available free of charge through the Investor Relations section of our website, www.trinseo.com, as soon as reasonably practicable after the reports are electronically filed or furnished with the SEC.

TRINSEO PLC

Notes to Condensed Consolidated Financial Statements

(Dollars in millions, unless otherwise stated)

(Unaudited)

NOTE 1—BASIS OF PRESENTATION

The unaudited interim condensed consolidated financial statements of Trinseo PLC and its subsidiaries (the “Company”) as of and for the periods ended March 31, 2022 and 2021 were prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and reflect all adjustments, consisting only of normal recurring adjustments, which, in the opinion of management, are considered necessary for the fair statement of the results for the periods presented. Because they cover interim periods, the statements and related notes to the financial statements do not include all disclosures normally provided in annual financial statements, and therefore, these statements should be read in conjunction with the 2021 audited consolidated financial statements included within the Company’s Annual Report on Form 10-K (“Annual Report”) filed with the Securities and Exchange Commission (“SEC”) on February 23, 2022. The Company’s condensed consolidated financial statements presented herein reflect the latest estimates and assumptions made by management that affect the reported amounts and related disclosures as of and for the period ended March 31, 2022. However, actual results could differ from these estimates and assumptions.

The December 31, 2021 condensed consolidated balance sheet data presented herein was derived from the Company’s December 31, 2021 audited consolidated financial statements, but does not include all disclosures required by GAAP for annual periods.

Certain prior year amounts have been reclassified to conform to the current year presentation. These reclassifications pertain primarily to the Company’s entry into an agreement during the second quarter of 2021 to sell its Synthetic Rubber business, as a result of which the Company reclassified its Synthetic Rubber assets and liabilities as held-for-sale and reclassified the operating results of its Synthetic Rubber business, net of taxes, as discontinued operations for all periods presented. The sale of the Synthetic Rubber business was completed in December 2021. Refer to Note 4 for further information. Throughout this Quarterly Report, unless otherwise indicated, amounts and activity are presented on a continuing operations basis.

NOTE 2—RECENT ACCOUNTING GUIDANCE

As of March 31, 2022, there was no recently issued accounting standards which would have a material effect on the Company’s condensed consolidated financial statements.

NOTE 3—ACQUISITIONS

Acquisition of Heathland B.V.

On January 3, 2022, the Company completed the acquisition of Heathland B.V. (“Heathland”) from Heathland Holding B.V. (“Heathland Holding”), through the purchase of all issued and outstanding shares (the “Heathland Acquisition”). The Heathland Acquisition was completed pursuant to the Sale and Purchase Agreement dated December 3, 2021 (“Heathland Agreement”), by and between the Company and Heathland Holding. Heathland is a leading collector and recycler of post-consumer and post-industrial plastic wastes in Europe. The total purchase price consideration is estimated to be $29.3 million, including an initial cash purchase price of $22.9 million, subject to customary working capital and other closing adjustments, as well as $6.4 million of contingent cash consideration, representing the fair value of certain earn-out payments. The maximum amount of potential earn-out payments is $6.8 million, which amounts will become payable to Heathland Holding as and when the related performance milestones or thresholds are achieved over the three-year period following the date of acquisition. The Heathland Acquisition was funded through existing cash on hand.

Table of Contents

Additionally, the Heathland Agreement includes a service fee of approximately $4.5 million, payable to Heathland Holdings contingent upon the continued employment of certain Heathland employees for three years following the acquisition date. The Company has not included this service fee as part of the estimated purchase price and instead will accrue for the service fee as compensation expense over the three-year period in which it is earned.

The Company accounted for the acquisition as a business combination pursuant to ASC 805. In accordance with ASC 805, fair values are assigned to tangible and identifiable intangible assets acquired and liabilities assumed at the acquisition date based on the information that was available as of the acquisition date. The Company believes that the information available provides a reasonable basis for estimating the fair values of assets acquired and liabilities assumed for the acquisition, however, preliminary measurements of fair value, are subject to change during the measurement period.

The Company allocated the purchase price of the acquisition to identifiable assets acquired and liabilities assumed based on their estimated fair values as of the acquisition date. The excess of the purchase price over the aggregate fair values was recorded as goodwill.

The table below summarizes the purchase price allocation for the assets acquired and liabilities assumed, based on their relative fair values, which have been assessed as of the January 3, 2022 acquisition date:

(1)The expected weighted average useful life of the acquired intangible assets are 7 years for customer relationships, tradenames and developed technology.
(2)Goodwill largely consists of strategic and synergistic opportunities resulting from combining Heathland with the Company’s existing businesses and is allocated entirely to the Base Plastics segment. No goodwill related to this acquisition is expected to be deductible for income tax purposes.

Pro forma results of operations information have not been presented as the effect of the acquisition is not material. The operating results of the Heathland acquisition are included within the Company's condensed consolidated statements of operations since the acquisition date of January 3, 2022 and were not material for the three months ended March 31, 2022. Pursuant to GAAP, costs incurred to complete the Heathland Acquisition as well as costs incurred to integrate into the Company’s operations are expensed as incurred. Transaction-related costs incurred, which are included within “Selling, general, and administrative expenses” in the condensed consolidated statements of operations, were not material for the three months ended March 31, 2022.

Acquisition of Aristech Surfaces

On September 1, 2021, the Company completed its previously announced acquisition of Aristech Surfaces LLC (“Aristech Surfaces”) from SK AA Holdings LLC (“SK AA Holdings”), the sole member of Aristech Surfaces, through purchase of 100% membership interest and intellectual property (the “Aristech Surfaces Acquisition”). The purchase price consideration for the Aristech Surfaces Acquisition amounted to was $449.5 million, all of which was paid for during the year ended December 31, 2021 (noting no cash flows during the three months ended March 31, 2021). Aristech Surfaces is a leading North America manufacturer and global provider of PMMA continuous cast and solid surface sheets, serving the wellness, architectural, transportation and industrial markets, whose results are included within the Engineered Materials segment. Aristech Surfaces’ products are used for a variety of applications, including the construction of hot tubs, swim spas, counter tops, signage, bath products and recreational vehicles.

The Company allocated the purchase price of the acquisition to identifiable assets acquired and liabilities assumed based on their estimated fair values as of the acquisition date. Refer to the Annual Report for further information. During the first quarter of 2022, there were no changes to the purchase price allocation for the acquisition of the Aristech Surfaces business. However, further adjustments may be necessary as a result of the Company’s on-going assessment of additional information that existed as of the acquisition date related to the fair value of assets acquired and liabilities assumed, including goodwill, during the measurement period.

On May 3, 2021, the Company completed its previously-announced acquisition of the polymethyl methacrylates (“PMMA”) and activated methyl methacrylates (“MMA”) business (together, the “PMMA business”) from Arkema S.A., (“Arkema”) through the purchase of 100% of the shares of certain subsidiaries of Arkema (the “PMMA Acquisition”). The purchase price consideration for the PMMA Acquisition was $1,364.9 million, all of which was paid for during the year ended December 31, 2021 (noting no cash flows during the three months ended March 31, 2021). PMMA is a transparent and rigid plastic with a wide range of end uses, and is an attractive adjacent chemistry which complements Trinseo’s existing offerings across several end markets including automotive, building & construction, medical and consumer electronics. PMMA results are included within the Engineered Materials segment.

The Company allocated the purchase price of the acquisition to identifiable assets acquired and liabilities assumed based on their estimated fair values as of the acquisition date. Refer to the Annual Report for further information. During the first quarter of 2022, there were no changes to the purchase price allocation for the acquisition of the PMMA business. However, further adjustments may be necessary as a result of the Company’s on-going assessment of additional information that existed as of the acquisition date related to the fair value of assets acquired and liabilities assumed, including goodwill, during the measurement period.

Unaudited Pro Forma Financial Information

The following unaudited pro forma financial information presents the consolidated results of operations of the Company with the PMMA business and Aristech Surfaces for the three months ended March 31, 2021 as if these acquisitions had occurred on January l, 2021. The proforma results were calculated by combining the results of Trinseo with the PMMA business and Aristech Surfaces but do not include adjustments related to cost savings or other synergies that are anticipated as a result of these acquisitions. Accordingly, these unaudited pro forma results are presented for informational purposes only and are not necessarily indicative of what the actual results of operations would have been if the acquisitions had occurred as of January 1, 2021, nor are they indicative of future results of operations.

NOTE 4—DIVESTITURES AND DISCONTINUED OPERATIONS

On December 1, 2021, the Company completed the divestiture of its Synthetic Rubber business to Synthos S.A. and certain of its subsidiaries (together, “Synthos”) for a purchase price of $402.4 million, which reflected a reduction of approximately $41.6 million for the assumption of pension liabilities by Synthos and $47.0 million for net working capital (excluding inventory) retained by Trinseo. Refer to the Annual Report for further information. At closing, the Company and Synthos executed a long-term supply agreement, in which Trinseo will supply Synthos certain raw materials used in the Synthetic Rubber business subsequent to the sale. For the three months ended March 31, 2022, the Company recorded $19.1 million in net sales and $16.2 million in cost of sales related to the supply agreement, which is recorded in continuing operations.

The following table summarizes the results of the Synthetic Rubber business for the three months ended March 31, 2022 and 2021, which are reflected as discontinued operations in the Company’s condensed consolidated statements of operations:

Amounts for operating net sales and costs of sales which had previously been eliminated in consolidation related to intercompany sales of styrene monomer to the Synthetic Rubber business are now reflected on a gross basis as a component of net sales and costs of sales from continuing operations for all periods presented. The Company has recast these amounts because upon completion of the sale of the Synthetic Rubber business, the Company will continue to have these ongoing transactions with Synthos, under a supply agreement executed in conjunction with the divestiture. Refer to Note 5 for recast segment net sales reflecting this adjustment.

Additionally, the Company previously allocated certain corporate management overhead costs to the former Synthetic Rubber segment which may no longer be allocated to discontinued operations under the relevant authoritative accounting guidance. Accordingly, the Company has recast its segment reporting results to reflect the reattribution of these expenses in all periods presented. Refer to Note 16 for recast segment results reflecting this adjustment.

NOTE 10—DERIVATIVE INSTRUMENTS

The Company’s ongoing business operations expose it to various risks, including fluctuating foreign exchange rates and interest rate risk. To manage these risks, the Company periodically enters into derivative financial instruments, such as foreign exchange forward contracts and interest rate swap agreements. The Company does not hold or enter into financial instruments for trading or speculative purposes. All derivatives are recorded on the condensed consolidated balance sheets at fair value.

Foreign Exchange Forward Contracts

Certain subsidiaries have assets and liabilities denominated in currencies other than their respective functional currencies, which creates foreign exchange risk. The Company’s principal strategy in managing its exposure to changes in foreign currency exchange rates is to naturally hedge the foreign currency-denominated liabilities on its balance sheet against corresponding assets of the same currency, such that any changes in liabilities due to fluctuations in exchange rates are offset by changes in their corresponding foreign currency assets. In order to further reduce this exposure, the Company also uses foreign exchange forward contracts to economically hedge the impact of the variability in exchange rates on assets and liabilities denominated in certain foreign currencies. The Company entered into a specific such foreign exchange forward contract in December 2020 in order to economically hedge the euro-denominated purchase price of the Arkema PMMA business, which was acquired on May 3, 2021, as discussed in Note 3. These derivative contracts are not designated for hedge accounting treatment.

As of March 31, 2022, the Company had open foreign exchange forward contracts with a notional U.S. dollar equivalent absolute value of $763.6 million. The following table displays the notional amounts of the most significant net foreign exchange hedge positions outstanding as of March 31, 2022:

New Taiwan Dollar

$

13.4

Mexican Peso

$

(13.4)

Open foreign exchange forward contracts as of March 31, 2022 had maturities occurring over a period of two months.

Foreign Exchange Cash Flow Hedges

The Company also enters into forward contracts, as deemed appropriate, with the objective of managing the currency risk associated with forecasted U.S. dollar-denominated raw materials purchases by one of its subsidiaries whose functional currency is the euro. By entering into these forward contracts, which are designated as cash flow hedges, the Company buys a designated amount of U.S. dollars and sells euros at the prevailing market rate to mitigate the risk associated with the fluctuations in the euro-to-U.S. dollar foreign currency exchange rates. The qualifying hedge contracts are marked-to-market at each reporting date and any unrealized gains or losses are included in Accumulated Other Comprehensive Income (“AOCI”) to the extent effective, and reclassified to cost of sales in the period during which the transaction affects earnings or it becomes probable that the forecasted transaction will not occur.

The Company had no open foreign exchange cash flow hedges as of March 31, 2022.

Interest Rate Swaps

On September 6, 2017, the Company issued the 2024 Term Loan B, which currently bears an interest rate of LIBOR plus 2.00%, subject to a 0.00% LIBOR floor. In order to reduce the variability in interest payments associated with the Company’s variable rate debt, during 2017 the Company entered into certain interest rate swap agreements to convert a portion of these variable rate borrowings into a fixed rate obligation. These interest rate swap agreements are designated as cash flow hedges, and as such, the contracts are marked-to-market at each reporting date and any

15

Table of Contents

unrealized gains or losses are included in AOCI to the extent effective, and reclassified to interest expense in the period during which the transaction affects earnings or it becomes probable that the forecasted transaction will not occur.

As of March 31, 2022, the Company had open interest rate swap agreements with a net notional U.S. dollar equivalent of $200.0 million which had an effective date of September 29, 2017 and mature in September 2022. Under the terms of the swap agreements, the Company is required to pay the counterparties a stream of fixed interest payments at a rate of 1.81%, and in turn, receives variable interest payments based on 1-month LIBOR (0.21% as of March 31, 2022) from the counterparties.

Net Investment Hedge

The Company accounts for its cross currency swaps (“CCS”) under the spot method, meaning that changes in the fair value of the hedge included in the assessment of effectiveness (changes due to spot foreign exchange rates) are recorded within AOCI, where they remain until either the sale or substantially complete liquidation of the subsidiary subject to the hedge. Additionally, the initial value of any component excluded from the assessment of effectiveness is recognized in income using a systematic and rational method over the life of the hedging instrument and any difference between the change in the fair value of the excluded component and amounts recognized in income under that systematic and rational method is recognized in AOCI. When applicable, the Company amortizes any initial excluded component value of a CCS as a reduction of “Interest expense, net” in the condensed consolidated statements of operations using the straight-line method over the remaining term of the related CCS. Additionally, interest receipts and payments are accrued under the terms of the Company’s CCS and are recognized within “Interest expense, net” in the condensed consolidated statements of operations.

The Company entered into a CCS arrangement (the “2017 CCS”) on September 1, 2017, swapping U.S. dollar principal and interest payments of $500.0 million at an interest rate of 5.375% on its 2025 Senior Notes for euro-denominated payments of €420.0 million at a weighted average interest rate of 3.45% for approximately five years. On February 26, 2020, the Company settled its 2017 CCS and replaced it with a new CCS arrangement (the “2020 CCS”) that carried substantially the same terms as the 2017 CCS. Under the 2020 CCS, the Company notionally exchanged $500.0 million at an interest rate of 5.375% for €459.3 million at a weighted average interest rate of 3.672% for approximately 2.7 years, with a final maturity of November 3, 2022. The cash flows under the 2020 CCS are aligned with the Company’s principal and interest obligations on its 5.375% 2025 Senior Notes. Refer to the Annual Report for further information.

Subsequent to the end of the first quarter, on April 7, 2022, the Company settled its existing 2020 CCS, which were set to mature in November 2022. Upon settlement of the 2020 CCS, the Company realized net cash proceeds of $1.9 million.

Forward contracts, interest rate swaps, and cross currency swaps are entered into with a limited number of counterparties, each of which allows for net settlement of all contracts through a single payment in a single currency in the event of a default on or termination of any one contract. As such, in accordance with the Company’s accounting policy, these derivative instruments are recorded on a net basis by counterparty within the condensed consolidated balance sheets.

Refer to Notes 11 and 18 of the condensed consolidated financial statements for further information regarding the fair value of the Company’s derivative instruments and the related changes in AOCI.

NOTE 11—FAIR VALUE MEASUREMENTS

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Assets and liabilities measured at fair value are classified using the following hierarchy, which is based upon the transparency of inputs to the valuation as of the measurement date.

Level 1—Valuation is based upon quoted prices (unadjusted) for identical assets or liabilities in active markets.

Level 2—Valuation is based upon quoted prices for similar assets and liabilities in active markets, or other inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument.

Level 3—Valuation is based upon other unobservable inputs that are significant to the fair value measurement.

The Company uses an income approach to value its derivative instruments, utilizing discounted cash flow techniques, considering the terms of the contract and observable market information available as of the reporting date, such as interest rate yield curves and currency spot and forward rates. Significant inputs to the valuation for these derivative instruments are obtained from broker quotations or from listed or over-the-counter market data, and are classified as Level 2 in the fair value hierarchy.

Nonrecurring Fair Value Measurements

The Company measured certain financial assets at fair value on a nonrecurring basis during the year ended December 31, 2021, which were still held as of March 31, 2022. These financial assets represent the Company’s styrene monomer assets in Boehlen, Germany, which it continues to operate. These assets were measured at fair value using underlying fixed asset records in conjunction with the use of industry experience and available market data, which are classified as Level 3 significant unobservable inputs in the fair value hierarchy. During the three months ended March 31, 2022, the Company recorded additional impairment charges of $0.7 million related to capital expenditures at the Boehlen styrene monomer facility that it determined to be impaired, which are also included within “Other charges” on the condensed consolidated statements of operations. Refer to the Company’s Annual Report for further information. As of March 31, 2022 and December 31, 2021, the value of the Boehlen styrene monomer assets are recorded at $3.3 million and $3.4 million, respectively, within the Company’s condensed consolidated balance sheets herein.

There were no other financial assets or liabilities measured at fair value on a nonrecurring basis as of December 31, 2021.

Provision for income taxes for the three months ended March 31, 2022 totaled $22.6 million, resulting in an effective tax rate of 56.9%. Provision for income taxes for the three months ended March 31, 2021 totaled $20.1 million, resulting in an effective tax rate of 23.4%.

The effective income tax rate for the three months ended March 31, 2022 was primarily impacted by an estimated liability of $35.6 million related to the European Commission request for information, as described within Note 13 in the condensed consolidated financial statements, for which the Company estimates no tax benefit based on currently available information.

NOTE 13—COMMITMENTS AND CONTINGENCIES

Environmental Matters

Accruals for environmental matters are recorded when it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated based on current law, existing technologies and other information. Pursuant to the terms of the agreement associated with the Company’s formation, the pre-closing environmental liabilities were retained by Dow, and Dow agreed, subject to temporal, monetary, and other limitations to indemnify the Company from and against environmental liabilities incurred or relating to the predecessor periods. Other than certain immaterial environmental liabilities assumed as part of the PMMA Acquisition and the Aristech Surfaces Acquisition, no environmental claims have been asserted or threatened against the Company. The Company is not a potentially responsible party for any material amounts at any Superfund Sites. As of March 31, 2022 and December 31, 2021, the Company had $4.2 million and $4.4 million, respectively, of accrued obligations for environmental remediation or restoration costs, which were recorded at fair value within the opening balance sheets of the PMMA business and Aristech Surfaces during 2021.

Inherent uncertainties exist in the Company’s potential environmental liabilities primarily due to unknown conditions, whether future claims may fall outside the scope of the indemnity, changing governmental regulations and legal standards regarding liability, and evolving technologies for handling site remediation and restoration. In connection with the Company’s existing indemnification, the possibility is considered remote that environmental remediation costs will have a material adverse impact on the condensed consolidated financial statements over the next 12 months.

Table of Contents

Purchase Commitments

In the normal course of business, the Company has certain raw material purchase contracts where it is required to purchase certain minimum volumes at current market prices. These commitments range from one to five years. In certain raw material purchase contracts, the Company has the right to purchase less than the required minimums and pay a liquidated damages fee, or, in case of a permanent plant shutdown, to terminate the contracts. In such cases, these obligations would be less than the annual commitment as disclosed in the Notes to Consolidated Financial Statements included in the Annual Report.

Litigation Matters

From time to time, the Company may be subject to various legal claims and proceedings incidental to the normal conduct of business, relating to such matters as employees, product liability, antitrust/competition, past waste disposal practices and release of chemicals into the environment. While it is impossible at this time to determine with certainty the ultimate outcome of these routine claims, the Company does not believe that the ultimate resolution of these claims will have a material adverse effect on the Company’s results of operations, financial condition or cash flow. Legal costs, including those legal costs expected to be incurred in connection with a loss contingency, are expensed as incurred.

European Commission Request for Information

On June 6, 2018, Trinseo Europe GmbH, a subsidiary of the Company, received a request for information in the form of a letter from the European Commission Directorate General for Competition (the “European Commission”) related to styrene monomer commercial activity in the European Economic Area. The Company subsequently commenced an internal investigation into these commercial activities and discovered instances of inappropriate activity. On October 28, 2019, a supplemental request for information was received from the European Commission. This request was limited to historical employment, entity, and organizational structures, along with certain financial, styrene purchasing, and styrene market information, as well as certain spot styrene purchase contracts. The Company has provided all information requested and continues to fully cooperate with the European Commission.

As a result of further developments in this matter, during the three months ended March 31, 2022, the Company recorded a reserve for an estimated liability of $35.6 million, which is included within “Other charges” on the condensed consolidated statements of operations. The Company is unable to predict the ultimate outcome of this matter, which remains ongoing. Based on its findings, the European Commission may decide to adopt a final decision imposing additional fines and/or request certain behavioral or structural commitments from the Company. However, any additional potential losses incurred could be material to the Company’s results of operations, balance sheet, and cash flows.

The Company had less than $0.1 million of net periodic benefit costs for its other postretirement plans for the three months ended March 31, 2022 and 2021.

Service cost related to the Company’s defined benefit pension plans and other postretirement plans is included within “Cost of sales” and “Selling, general and administrative expenses,” whereas all other components of net periodic benefit cost are included within “Other expense, net” in the condensed consolidated statements of operations. As of March 31, 2022 and December 31, 2021, the Company’s benefit obligations included primarily in “Other noncurrent obligations” in the condensed consolidated balance sheets were $271.8 million and $274.7 million, respectively.

The Company made cash contributions and benefit payments to unfunded plans of approximately $2.5 million during the three months ended March 31, 2022. The Company expects to make additional cash contributions, including benefit payments to unfunded plans, of approximately $6.5 million to its defined benefit plans for the remainder of 2022.

The expected volatility assumption is determined based on the historical volatility of the Company’s publicly traded ordinary shares. The expected term of option awards represents the period of time that option awards granted are expected to be outstanding. For the option awards granted during the three months ended March 31, 2022, the simplified method was used to calculate the expected term, given the Company’s limited historical exercise data. The risk-free interest rate for the periods within the expected term of option awards is based on the U.S. Treasury yield curve in effect at the time of grant. The dividend yield is estimated based on historical and expected dividend activity.

Performance Share Units (PSUs)

The following are the weighted average assumptions used within the Monte Carlo valuation model for PSUs granted during the three months ended March 31, 2022:

Determining the fair value of PSUs requires considerable judgment, including estimating the expected volatility of the price of the Company’s ordinary shares, the correlation between the Company’s share price and that of its peer companies, and the expected rate of interest. The expected volatility for each grant is determined based on the historical volatility of the Company’s ordinary shares. The expected term of PSUs represents the length of the performance period. The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant for a duration equivalent to the performance period. The share price is the closing price of the Company’s ordinary shares on the grant date.

NOTE 16—SEGMENTS

As discussed in the Annual Report, beginning in the second quarter of 2021, the Company reported the results of the Synthetic Rubber business as discontinued operations in the condensed consolidated statements of operations for all periods presented, and therefore it is no longer presented as a separate reportable segment. Refer to Note 4 for further information. The information in the tables below has been retroactively adjusted to reflect these changes in reporting segments.

24

Table of Contents

The Engineered Materials segment includes the Company’s compounds and blends products sold into higher growth and value applications, such as consumer electronics and medical, as well as soft thermoplastic elastomers (“TPEs”) products which are sold into markets such as footwear and automotive. Additionally, following the PMMA Acquisition on May 3, 2021 and the Aristech Surfaces Acquisition on September 1, 2021, the Engineered Materials segment also includes PMMA and MMA products, which are sold into a variety of applications including automotive, building & construction, medical, consumer electronics, and wellness, among others. The Latex Binders segment produces styrene-butadiene latex (“SB latex”) and other latex polymers and binders, primarily for coated paper and packaging board, carpet and artificial turf backings, as well as a number of performance latex binders applications, such as adhesive, building and construction and the technical textile paper market. The Base Plastics segment contains the results of the acrylonitrile-butadiene-styrene (“ABS”), styrene-acrylonitrile (“SAN”), and polycarbonate (“PC”) businesses, as well as compounds and blends for automotive and other applications. The Base Plastics segment also includes the results of Heathland, which was acquired in the first quarter of 2022. The Polystyrene segment includes a variety of general purpose polystyrenes (“GPPS”) and polystyrene that has been modified with polybutadiene rubber to increase its impact resistant properties (“HIPS”). The Feedstocks segment includes the Company’s production and procurement of styrene monomer outside of North America, which is used as a key raw material in many of the Company’s products, including polystyrene, SB latex, and ABS resins. Lastly, the Americas Styrenics segment consists solely of the operations of the Company’s 50%-owned joint venture, Americas Styrenics, a producer of both styrene monomer and polystyrene in North America.

The following table provides disclosure of the Company’s segment Adjusted EBITDA, which is used to measure segment operating performance and is defined below, for the three months ended March 31, 2022 and 2021. Asset and intersegment sales information by reporting segment is not regularly reviewed or included with the Company’s reporting to the chief operating decision maker. Therefore, this information has not been disclosed below. Refer to Note 5 for the Company’s net sales to external customers by segment for the three months ended March 31, 2022 and 2021.

The Company’s primary measure of segment operating performance is Adjusted EBITDA, which is defined as income from continuing operations before interest expense, net; provision for income taxes; depreciation and amortization expense; loss on extinguishment of long-term debt; asset impairment charges; gains or losses on the dispositions of businesses and assets; restructuring charges; acquisition related costs and benefits and other items. Segment Adjusted EBITDA is a key metric that is used by management to evaluate business performance in comparison to budgets, forecasts, and prior year financial results, providing a measure that management believes reflects core operating performance by removing the impact of transactions and events that would not be considered a part of core operations. Other companies in the industry may define segment Adjusted EBITDA differently than the Company, and as a result, it may be difficult to use segment Adjusted EBITDA, or similarly named financial measures, that other companies may use to compare the performance of those companies to the Company’s segment performance.

In connection with this restructuring program, during the three months ended March 31, 2022, the Company incurred employee termination benefits charges of $0.3 million. The Company expects to incur incremental employee termination benefit charges related to impacted employees as of March 31, 2022 of less than $1.0 million, the majority of which are expected to be paid by December 31, 2022. As this was identified as a corporate-related activity, the charges related to this restructuring program were not allocated to a specific segment, but rather included within corporate unallocated.

The following table provides a roll forward of the liability balances associated with the Company’s restructuring activities as of March 31, 2022.

NOTE 19—EARNINGS PER SHARE

Basic earnings per ordinary share (“basic EPS”) is computed by dividing net income available to ordinary shareholders by the weighted average number of the Company’s ordinary shares outstanding for the applicable period. Diluted earnings per ordinary share (“diluted EPS”) is calculated using net income available to ordinary shareholders divided by diluted weighted average ordinary shares outstanding during each period, which includes unvested RSUs, option awards, and PSUs. Diluted EPS considers the impact of potentially dilutive securities except in periods in which there is a loss from continuing operations because the inclusion of the potential ordinary shares would have an anti-dilutive effect.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

2022 Year-to-Date Highlights

During the three months ended March 31, 2022, Trinseo recognized net income from continuing operations of $17.1 million and Adjusted EBITDA of $177.6 million. This was a solid start to the year, where Trinseo has successfully continued providing quality products and unique solutions to our customers, despite the challenging business environment as geopolitical factors in Europe pressured supply chains, customer production and energy costs in the region. Refer to the discussion below for further information and refer to “Non-GAAP Performance Measures” for discussion of our use of non-GAAP measures in evaluating our performance and a reconciliation of these measures. Other highlights for the year are described below.

European Commission Request for Information

In 2018, Trinseo received a request for information from the European Commission Directorate General for Competition (the “European Commission”) related to styrene monomer commercial activity in the European Economic Area, as well as subsequent requests for information. Trinseo has fully responded to all information requests from the European Commission and continues to fully cooperate on this matter, which remains ongoing. As a result of further developments in this matter, during the three months ended March 31, 2022, Trinseo recorded a reserve for an estimated liability of $35.6 million. Refer to Note 13 in the condensed consolidated financial statements for more information.

Acquisition of Heathland

On January 3, 2022, the Company closed on the previously-announced acquisition of Heathland B.V. (“Heathland”) for an estimated purchase price of $29.3 million, including an initial cash purchase price of $22.9 million, subject to customary working capital and other closing adjustments, as well as $6.4 million of contingent cash consideration, representing the fair value of certain earn-out payments (the “Heathland Acquisition”). Heathland is based in Utrecht, the Netherlands, and is focused on converting post-consumer and post-industrial PMMA, PC, ABS, polystyrene, and other thermoplastic waste for use in a wide range of high-end applications. The acquisition of Heathland is consistent with Trinseo’s strategy and enhances our footprint as a sustainable solutions provider. Refer to Note 3 in the condensed consolidated financial statements for more information.

Exploration of Divestiture of Styrenics Businesses

Trinseo has continued to progress our work on exploring the divesture of our styrenics businesses, including the formal sales process which was launched in January 2022. The scope of this potential divestiture is expected to include the Feedstocks and Polystyrene reporting segments as well as our 50% ownership of Americas Styrenics.

Three Months Ended – March 31, 2022 vs. March 31, 2021

Net Sales

Of the 41% increase in net sales, 26% was attributable to increased selling prices, mainly due to the pass through of higher raw material costs, such as styrene, along with higher energy costs. The majority of the remaining increase was due to contributions from our acquisitions in 2021, including the PMMA Acquisition, which closed on May 3, 2021, and the Aristech Surfaces Acquisition, which closed on September 1, 2021.

Cost of Sales

The 52% increase in cost of sales was primarily attributable to a 23% increase in raw material costs and a 27% increase related to the PMMA Acquisition and Aristech Surfaces Acquisition.

Gross Profit

The decrease in gross profit of 7% was primarily attributable to lower margins compared to the very high levels observed in the first quarter of 2021 in Feedstocks and lower sales volume to automotive applications in Base Plastics. These impacts were partially offset by additional gross profit from the 2021 acquisitions. See the segment discussion below for further information.

Selling, General and Administrative Expenses (SG&A)

The $40.2 million, or 71%, increase in SG&A was primarily due to a $19.1 million increase in costs associated with the Company’s strategic initiatives, including the potential divestiture of our Styrenics business, as well as $2.1 million of costs incurred in connection with the Company’s enterprise resource planning system upgrade. Also contributing to the increase was a $10.0 million increase in personnel costs due to the addition of personnel from acquisitions, a $3.4 million increase in additional depreciation and amortization expense from the PMMA Acquisition and the Aristech Surfaces Acquisition, and a $1.6 million increase in bad debt expense. Slightly offsetting these increases was a decrease of $2.8 million related to acquisition transaction and integration costs incurred, primarily in connection with the PMMA Acquisition.

Table of Contents

Equity in Earnings of Unconsolidated Affiliates

The decrease in equity earnings of $1.3 million was due to lower equity earnings from Americas Styrenics.

Other Charges

During the three months ended March 31, 2022, the Company recorded an estimated liability of $35.6 million related to the European Commission request for information, as described within Note 13 in the condensed consolidated financial statements. The Company also recorded impairment charges of $0.7 million related to our Boehlen styrene monomer assets, as described within Note 11 in the condensed consolidated financial statements.

Interest Expense, Net

The increase in interest expense, net of $9.9 million, or 83%, was primarily attributable to the Company’s issuance of the 2029 Senior Notes, which were not issued until late in the first quarter of 2021 and the 2028 Term Loan B, issued in the second quarter of 2021. Refer to Note 8 in the condensed consolidated financial statements for further information.

Other Expense, Net

Other expense, net for the three months ended March 31, 2022 was $3.0 million, which included a $1.2 million of expense related to the non-service cost components of net periodic benefit cost as well as foreign exchange transaction losses of $1.4 million. These net foreign exchange transaction losses included $10.2 million of losses primarily from the remeasurement of our euro denominated payables due to the relative changes in rates between the U.S. dollar and the euro during the period, partially offset by $8.8 million of gains from our foreign exchange forward contracts.

Other expense, net for the three months ended March 31, 2021 was $2.4 million, which included $1.8 million of expense related to the non-service cost components of net periodic benefit cost as well as foreign exchange transaction losses of $0.2 million. These net foreign exchange transaction losses included $19.9 million of losses primarily from the remeasurement of our euro-denominated payables due to the relative changes in rates between the U.S. dollar and the euro during the period, almost entirely offset by $19.7 million of gains from our foreign exchange forward contracts, excluding the acquisition purchase price hedge.

Provision for Income Taxes

Provision for income taxes for the three months ended March 31, 2022 totaled $22.6 million, resulting in an effective tax rate of 56.9%. Provision for income taxes for the three months ended March 31, 2021 totaled $20.1 million, resulting in an effective tax rate of 23.4%.

The increase in provision for income taxes was primarily driven by the Company’s forecasted jurisdictional mix of earnings, where losses expected to be generated in lower rate jurisdictions are being more than offset by income expected to be generated in higher tax jurisdictions.

Net Income (Loss) from Discontinued Operations, Net of Income Taxes

Net income (loss) from discontinued operations, net of income taxes during the three months ended March 31, 2022 and 2021 was $(0.4) million and $5.7 million, respectively, and was related the results of our Synthetic Rubber business. Refer to Note 4 in the condensed consolidated financial statements for further information.

Outlook

We expect a year of solid earnings due to healthy end market demand, cost synergy realization from our acquired businesses, and effective pricing and commercial excellence programs. These drivers help to mitigate the headwinds from supply chain constraints, higher energy costs, and current styrene production outages at our Terneuzen site and at Americas Styrenics’ St. James site. We remain focused on our transformation to a specialty material and sustainable solutions provider, including progressing on the sale process of the Styrenics businesses.

The 349% increase in net sales was primarily attributable to the contribution from the PMMA business and the Aristech Surfaces acquisitions. Excluding these acquisitions, sales price, primarily from the pass through of higher raw materials and energy costs, positively impacted net sales by 19%, which was offset by a 17% decrease due to lower sales volumes as demand declined from very high levels in the prior year.

Adjusted EBITDA increased $26.8 million, or 339%, of which $31.2 million, or 393% was attributable to the contribution from the PMMA business and Aristech Surfaces acquisitions. Excluding these acquisitions, a $3.4 million, or 42%, decrease was due to lower sales volume as demand eased from very high prior year levels for consumer electronic and medical applications, as well as a $1.3 million decrease due to higher fixed costs.

Latex Binders Segment

Our Latex Binders segment produces styrene-butadiene latex (“SB latex”) and other latex polymers and binders primarily for coated paper and packaging board, carpet and artificial turf backings, as well as a broad range of performance latex binders products, including SB latex, styrene-acrylate latex (“SA latex”), and vinylidene chloride latex for coatings, adhesives, sealants, and elastomers (“CASE”) applications.

Three Months Ended – March 31, 2022 vs. March 31, 2021

The 22% increase in net sales was primarily due to a 29% increase in pricing from the pass through of raw material costs, mainly styrene and butadiene. Lower sales volume, mainly attributable to paper and carpet applications, decreased net sales by 4%.

The $13.4 million, or 80%, increase in Adjusted EBITDA was primarily due to an increase of $18.9 million, or 112%, attributable to higher margins which was a result of favorable net timing. This effect more than offset the $2.0 million, or 12%, decrease due to lower sales volumes, as well as a $2.0 million, or 12%, decrease due to higher fixed costs.

Base Plastics Segment

Our Base Plastics segment consists of a variety of compounds and blends, the majority of which are for automotive applications. The segment also includes our acrylonitrile-butadiene-styrene (“ABS”), styrene-acrylonitrile (“SAN”), and polycarbonate (“PC”) businesses. The Base Plastics segment also includes the results of Heathland, which was acquired in the first quarter of 2022. However, this did not have a material impact on sales or Adjusted EBITDA for the period.

Of the 21% increase in net sales, 31% was due to higher pricing from the pass through of raw material costs and pricing actions. The increase from higher pricing was slightly offset by a 4% decrease due to foreign exchange rate impacts as well as a 7% decrease due to lower sales volume.

The $3.3 million, or 5%, increase in Adjusted EBITDA was primarily due to higher margins of $18.7 million, or 29%, particularly in ABS. Higher margins were partially offset by a decrease of $6.8 million, or 10%, due to lower volumes, mostly in automotive applications, as supply chain constraints caused by semi-conductor shortages and the Ukraine conflict caused production issues for customers. Also offsetting the higher margins was a decrease of $4.3 million, or 7%, due to foreign exchange impacts, and a decrease of $4.7 million, or 7%, due to higher fixed costs.

Polystyrene Segment

Our product offerings in our Polystyrene segment include a variety of general purpose polystyrenes (“GPPS”) and polystyrene that has been modified with polybutadiene rubber to increase its impact resistant properties (“HIPS”). These products provide customers with performance and aesthetics at a low cost across applications, including appliances, packaging, including food packaging and food service disposables, consumer electronics, and building and construction materials. In April 2021, the Company announced our plans to build a full commercial scale polystyrene recycling plant in Tessenderlo, Belgium, which is expected to be operational in 2023.

Three Months Ended – March 31, 2022 vs. March 31, 2021

Of the 19% increase in net sales, 18% of the increase was due to higher pricing primarily from the pass through of higher styrene costs as well as commercial excellence actions.

The $2.1 million, or 4%, decrease in Adjusted EBITDA was primarily due to a decrease of $2.7 million, or 6%, due to higher fixed costs, and a decrease of $2.3 million, or 5%, due to lower volumes. These effects were partially offset by an increase due to higher margins of $1.8 million, or 4%, including impacts from commercial excellence actions, as well as an increase of $1.1 million, or 2%, due to foreign exchange rate impacts.

Feedstocks Segment

The Feedstocks segment includes the Company’s production and procurement of styrene monomer outside of North America, which is used as a key raw material for the production of polystyrene, expandable polystyrene, SAN resins, SA latex, SB latex, ABS resins, unsaturated polyethylene resins, and styrene-butadiene rubber.

Of the 4% decrease in net sales, 29% was due to lower styrene-related sales volume. This effect was mostly offset by a 25% increase due to higher styrene prices.

The decrease of $42.2 million in Adjusted EBITDA was primarily attributed to a $48.0 million, or 104%, decrease due to lower styrene margins including impacts from higher utility costs caused by rise in natural gas prices in Europe. Slightly offsetting this decrease was an increase of $3.6 million, or 8%, due to foreign exchange impacts.

Americas Styrenics Segment

This segment consists solely of the equity earnings from of our 50%-owned joint venture, Americas Styrenics, a producer of both styrene monomer and polystyrene in North America. Styrene monomer is a basic building block of plastics and a key input to many of the Company’s products, as well as a key raw material for the production of polystyrene. Major applications for the polystyrene products Americas Styrenics produces include appliances, food packaging, food service disposables, consumer electronics, and building and construction materials.

Three Months Ended – March 31, 2022 vs. March 31, 2021

The decrease in Adjusted EBITDA was mainly due to lower styrene profitability, as a result of lower margins as well as a production outage in the current period, which was mostly offset by higher polystyrene margins.

Non-GAAP Performance Measures

We present Adjusted EBITDA as a non-GAAP financial performance measure, which we define as income from continuing operations before interest expense, net; provision for income taxes; depreciation and amortization expense;

35

Table of Contents

loss on extinguishment of long-term debt; asset impairment charges; gains or losses on the dispositions of businesses and assets; restructuring charges; acquisition related costs and other items. In doing so, we are providing management, investors, and credit rating agencies with an indicator of our ongoing performance and business trends, removing the impact of transactions and events that we would not consider a part of our core operations.

There are limitations to using the financial performance measures such as Adjusted EBITDA. This performance measure is not intended to represent net income or other measures of financial performance. As such, it should not be used as an alternative to net income as an indicator of operating performance. Other companies in our industry may define Adjusted EBITDA differently than we do. As a result, it may be difficult to use this or similarly-named financial measures that other companies may use, to compare the performance of those companies to our performance. We compensate for these limitations by providing a reconciliation of this performance measure to our net income, which is determined in accordance with GAAP.

Adjusted EBITDA is calculated as follows for the three months ended March 31, 2022 and 2021:

(a)EBITDA is a non-GAAP financial performance measure that we refer to in making operating decisions because we believe it provides our management as well as our investors and credit agencies with meaningful information regarding the Company’s operational performance. We believe the use of EBITDA as a metric assists our board of directors, management and investors in comparing our operating performance on a consistent basis. Other companies in our industry may define EBITDA differently than we do. As a result, it may be difficult to use EBITDA, or similarly-named financial measures that other companies may use, to compare the performance of those companies to our performance. We compensate for these limitations by providing reconciliations of our EBITDA results to our net income, which is determined in accordance with GAAP.
(b)Restructuring and other charges for the three months ended March 31, 2022 primarily relate to the employee termination benefit charges incurred in connection with the Company’s transformational restructuring program, announced in the second quarter of 2021. Restructuring and other charges for the three months ended March 31, 2021 primarily relate to the Company’s other restructuring activities.

Operating Activities

Net cash used in operating activities from continuing operations during the three months ended March 31, 2022 totaled $5.2 million. Solid earnings, including $7.5 million of dividends received from Americas Styrenics, were more than offset by a significant working capital build during the quarter. This working capital build was driven by significantly increasing raw material and utility prices, coupled with a build of inventory ahead of planned turnaround activities. Net cash provided by operating activities from discontinued operations during the three months ended March 31, 2022 totaled $0.2 million.

Net cash provided by operating activities from continuing operations during the three months ended March 31, 2021 totaled $40.7 million, inclusive of $15.0 million of dividends received from Americas Styrenics. Net cash used in operating assets and liabilities for the three months ended March 31, 2021 totaled $84.5 million, noting an increase in accounts receivable of $138.8 million as well as an increase in inventories of $82.5 million. These effects were partially offset by an increase in accounts payable and other current liabilities of $114.9 million, an increase in other liabilities of $12.3 million, and an increase in income taxes payable of $4.9 million. The increases in accounts receivable, inventories, and accounts payable and other current liabilities during the period were primarily attributable to increased sales volume across all segments except for Feedstocks as well as increased prices, including both raw material prices and selling prices due to our pass through pricing arrangements. Net cash provided by operating activities from discontinued operations during the three months ended March 31, 2021 totaled $10.3 million, and was primarily attributable to raw material cost increases and higher inventory related to discontinued operations.

Table of Contents

Investing Activities

Net cash used in investing activities from continuing operations during the three months ended March 31, 2022 totaled $46.1 million, which was primarily attributable to net cash paid for asset or business acquisitions of $22.2 million (see Note 3), and capital expenditures, including cash spent for our ongoing ERP upgrade, of $23.9 million. Net cash used in investing activities from discontinued operations during the three months ended March 31, 2022 totaled $0.9 million.

Net cash used in investing activities from continuing operations during the three months ended March 31, 2021 totaled $11.2 million, which was entirely attributable to capital expenditures. Net cash used in investing activities from discontinued operations during the three months ended March 31, 2021 totaled $1.4 million, which was entirely attributable to capital expenditures.

Financing Activities

Net cash used in financing activities during the three months ended March 31, 2022 totaled $70.6 million. This activity was primarily due to $51.9 million of payments related to the repurchase of ordinary shares, $12.4 million of dividends paid, $3.6 million of net repayments of short-term borrowings, and $3.6 million of net principal payments related to our 2024 Term Loan B and 2028 Term Loan B during the period. This activity was partially offset by $1.7 million in proceeds from the exercise of option awards during the period.

Net cash provided by financing activities during the three months ended March 31, 2021 totaled $450.8 million. This activity was primarily due to $450.0 million in proceeds from the issuance of the 2029 Senior Notes as well as $9.0 million in proceeds from the exercise of option awards. This activity was partially offset by $3.3 million of dividends payments, $2.8 million of net repayments of short-term borrowings, and $1.3 million of deferred financing fees related to the issuance of our 2029 Senior Notes during the period.

Free Cash Flow

We use Free Cash Flow as a non-GAAP measures to evaluate and discuss the Company’s liquidity position and results. Free Cash Flow is defined as cash from operating activities, less capital expenditures. We believe that Free Cash Flow provides an indicator of the Company’s ongoing ability to generate cash through core operations, as it excludes the cash impacts of various financing transactions as well as cash flows from business combinations that are not considered organic in nature. We also believe that Free Cash Flow provides management and investors with useful analytical indicator of our ability to service our indebtedness, pay dividends (when declared), and meet our ongoing cash obligations.

Free Cash Flow is not intended to represent cash flows from operations as defined by GAAP, and therefore, should not be used as an alternative for that measure. Other companies in our industry may define Free Cash Flow differently than we do. As a result, it may be difficult to use this or similarly-named financial measures that other companies may use, to compare the liquidity and cash generation of those companies to our own. We compensate for these limitations by providing a reconciliation to cash provided by operating activities from continuing operations, which is determined in accordance with GAAP.

Refer to the discussion above for significant impacts to cash provided by operating activities for the three months ended March 31, 2022 and 2021.

Capital Resources and Liquidity

We require cash principally for day-to-day operations, to finance capital investments and other initiatives, to purchase materials, to service our outstanding indebtedness, and to fund the return of capital to shareholders via dividend

payments and ordinary share repurchases, when deemed appropriate. Our sources of liquidity include cash on hand, cash flow from operations from continuing operations, and amounts available under the Senior Credit Facility and the Accounts Receivable Securitization Facility (discussed further below).

At March 31, 2022 and December 31, 2021, we had $2,365.2 million and $2,368.8 million, respectively, in outstanding indebtedness and $1,045.9 million and $1,064.1 million, respectively, in working capital (calculated as current assets from continuing operations less current liabilities from continuing operations). In addition, as of March 31, 2022 and December 31, 2021, we had $445.0 million and $560.6 million, respectively, of foreign cash and cash equivalents on our balance sheet, outside of our country of domicile, which was Ireland as of March 31, 2022, all of which is readily convertible into other foreign currencies, including the U.S. dollar. Our intention is not to permanently reinvest our foreign cash and cash equivalents. Accordingly, we record deferred income tax liabilities related to the unremitted earnings of our subsidiaries.

The following table outlines our outstanding indebtedness as of March 31, 2022 and December 31, 2021 and the associated interest expense, including amortization of deferred financing fees and debt discounts. Effective interest rates for the borrowings included in the table below exclude the impact of deferred financing fee amortization, certain other fees charged to interest expense (such as fees for unused commitment fees during the period), and the impacts of derivatives designated as hedging instruments. For definitions of capitalized terms not included herein, refer to our Annual Report on Form 10-K (“Annual Report”).

*For the three months ended March 31, 2022, interest expense on “Other indebtedness” totaled less than $0.1 million.

As of March 31, 2022, our Senior Credit Facility included the 2026 Revolving Facility, which is scheduled to mature in May 2026 and had a borrowing capacity of $375.0 million. As of March 31, 2022, the Company had $368.6 million of funds available for borrowing (net of $6.4 million outstanding letters of credit) under the 2026 Revolving Facility. Further, as of March 31, 2022, the Company is required to pay a quarterly commitment fee in respect of any unused commitments under the 2026 Revolving Facility equal to 0.375% per annum.

Also included in our Senior Credit Facility is our 2024 Term Loan B (with original principal of $700.0 million, maturing in September 2024), and our 2028 Term Loan B (with original principal of $750.0 million, maturing in May 2028).

Our 2025 Senior Notes, as issued under the Indenture executed in 2017, include $500.0 million aggregate principal amount of 5.375% senior notes that mature on September 1, 2025.

Our 2029 Senior Notes, as issued under the Indenture executed in 2021, include $450.0 million aggregate principal amount of 5.125% senior notes that mature on April 1, 2029.

We also continue to maintain our Accounts Receivable Securitization Facility, which matures in November 2024 and has an outstanding borrowing capacity of $150.0 million. As of March 31, 2022, there were no amounts outstanding under this facility and the Company had approximately $145.7 million of accounts receivable available to support this

39

Table of Contents

facility, based on the pool of eligible accounts receivable. Refer to Note 8 in the consolidated financial statements for further information on the facility.

Our ability to raise additional financing and our borrowing costs may be impacted by short- and long-term debt ratings assigned by independent rating agencies, which are based, in significant part, on our performance as measured by certain credit metrics such as interest coverage and leverage ratios.

We and our subsidiaries, affiliates or significant shareholders may from time to time seek to retire or purchase our outstanding debt through cash purchases in the open market, privately negotiated transactions, exchange transactions or otherwise. Such repurchases or exchanges, if any, will depend on prevailing market conditions, our liquidity requirements, contractual restrictions and other factors. The amounts involved may be material.

Trinseo Materials Operating S.C.A. and Trinseo Materials Finance, Inc. (the “Issuers” of our 2029 Senior Notes and 2025 Senior Notes and “Borrowers” under our Senior Credit Facility) are dependent upon the cash generation and receipt of distributions and dividends or other payments from our subsidiaries and joint venture in order to satisfy their debt obligations. There are no known significant restrictions by third parties on the ability of subsidiaries of the Company to disburse or dividend funds to the Issuers and the Borrowers in order to satisfy these obligations. However, as the Company’s subsidiaries are located in a variety of jurisdictions, the Company can give no assurances that our subsidiaries will not face transfer restrictions in the future due to regulatory or other reasons beyond our control.

The Senior Credit Facility and Indentures also limit the ability of the Borrowers and Issuers, respectively, to pay dividends or make other distributions to Trinseo PLC, which could then be used to make distributions to shareholders. During the three months ended March 31, 2022, the Company declared dividends of $0.32 per ordinary share, totaling $12.1 million, all of which was accrued as of March 31, 2022 and which was paid in April 2022. These dividends are well within the available capacity under the terms of the restrictive covenants contained in the Senior Credit Facility and Indentures. Further, additional capacity continues to be available under the terms of these covenants to support expected future dividends to shareholders, should the Company continue to declare them.

Our ability to generate cash from operations to pay our indebtedness and meet other liquidity needs is subject to certain risks described herein and under Part I, Item 1A-“Risk Factors” of our Annual Report, as well as the risk factors included in Part II, Item 1A herein. As of March 31, 2022, we were in compliance with all the covenants and default provisions under our debt agreements. Refer to our Annual Report for further information on the details of the covenant requirements.

The ongoing war in Ukraine and the corresponding sanctions and other measures being imposed by various governments have impacted global markets, particularly in Europe, leading to: (i) high volatility and increasing prices for natural gas and other energy supplies, (ii) changing trade flow patterns, and (iii) increasing levels of economic and geopolitical uncertainty globally. We do not have manufacturing operations in Ukraine, Russia or Belarus, and we have temporarily suspended sales and deliveries to Russia and Belarus, which sales do not constitute a material portion of our business. However, a significant escalation or expansion of economic disruption caused by this conflict, including supply disruptions, higher costs of raw materials or energy could have a material adverse effect on our results of operations, financial condition and cash flows. We are actively monitoring the broader economic impact from the crisis, in particular on the price and availability of raw materials and energy.

Contractual Obligations and Commercial Commitments

There have been no material revisions outside the ordinary course of business to our contractual obligations as described within “Management’s Discussion and Analysis of Financial Condition and Results of Operations – Contractual Obligations and Commercial Commitments” within our Annual Report.

Critical Accounting Policies and Estimates

Our unaudited interim condensed consolidated financial statements are based on the selection and application of significant accounting policies. The preparation of unaudited interim condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and revenues and expenses at the date of and during the reporting period. Actual results could differ from those estimates. However, we are not currently aware of any reasonably likely events or circumstances that would result in materially different results.

We describe our significant accounting policies in Note 2, Basis of Presentation and Summary of Significant Accounting Policies, in the Notes to Consolidated Financial Statements included in our Annual Report, while we discuss our critical accounting policies and estimates in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” within our Annual Report. There have been no material revisions to the significant accounting policies or critical accounting policies and estimates as filed in our Annual Report.

Off-Balance Sheet Arrangements

We do not have any off-balance sheet arrangements.

Recent Accounting Pronouncements

We describe the impact of recent accounting pronouncements in Note 2 of our condensed consolidated financial statements, included elsewhere within this Quarterly Report.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

As discussed in “Quantitative and Qualitative Disclosures About Market Risk” within our Annual Report, we are exposed to changes in interest rates and foreign currency exchange rates as well as changes in the prices of certain commodities that we use in production. There have been no material changes in our exposure to market risks from the information provided within our Annual Report.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Our management is responsible for establishing and maintaining internal controls designed to provide reasonable assurance that information required to be disclosed by us in our reports that we file or submit under the Exchange Act (as defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934, as amended) is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, with the participation of our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosures. Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of the Company’s disclosure controls and procedures as of March 31, 2022. Based on that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures as of the end of the period covered by this Quarterly Report were effective to provide the reasonable level of assurance described above.

Changes in Internal Control over Financial Reporting

There was no additional changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act) that occurred during the quarter ended March 31, 2022 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II — OTHER INFORMATION

Item 1. Legal Proceedings

From time to time we may be subject to various legal claims and proceedings incidental to the normal conduct of business, relating to such matters as product liability, antitrust, competition, waste disposal practices, release of chemicals into the environment and other matters that may arise in the ordinary course of our business. Other than the European Commission request for information described in Note 13 – Commitments and Contingencies, we currently believe that there is no litigation pending that is likely to have a material adverse effect on our business. Regardless of the outcome, legal proceedings can have an adverse impact on us because of defense and settlement costs, diversion of management resources and other factors. For information regarding material developments in legal proceedings during the quarter ended March 31, 2022, see “Litigation Matters” and “European Commission Request for Information” in Note 13 to our condensed consolidated financial statements.

Table of Contents

Item 1A. Risk Factors

Our business faces various risks. Certain important factors may have a material adverse effect on our business prospects, financial condition and results of operations, and you should carefully consider them. Accordingly, in evaluating our business, we encourage you to consider the risk factors related to our ordinary shares as well those risk factors related to our business and industry which have been previously disclosed in Part 1, Item 1A of our Annual Report for the year ended December 31, 2021. Certain material updates to these risk factors are included below.

We encourage you to consider these risks, in their entirety, in addition to other information contained in or incorporated by reference into this Quarterly Report and our other public filings with the SEC. Other events that we do not currently anticipate or that we currently deem immaterial may also affect our business, prospects, financial condition and results of operations.

Risks Related to Our Operations

Volatility in the cost of raw materials, logistics services, energy, or transportation utilized for our products, or disruption in the supply of the raw materials utilized for our products, may adversely affect our financial condition and results of operations or cause our financial results to differ materially from our forecasts.

Our results of operations can be directly affected, positively and negatively, by volatility in the cost of our raw materials, which are subject to global supply and demand and other factors beyond our control. Our principal raw materials (benzene, ethylene, butadiene, BPA, MMA, and styrene) together represent approximately 81% of our total cost of goods sold. Additionally, we use natural gas and electricity to operate our facilities and generate heat and steam for our various manufacturing processes. Crude oil prices also impact our raw material and energy costs. Generally, higher crude oil prices lead to higher costs of natural gas and raw materials, although some raw materials are impacted less than others. Volatility in the cost of energy or raw materials makes it more challenging to manage pricing and pass the increases on to our customers in a timely manner. We believe that rapid changes in pricing also can affect the volume our customers consume. As a result, our gross profit and margins could also be adversely affected and our financial results may differ materially from our forecasts. The ongoing war in Ukraine has impacted global energy markets, particularly in Europe, leading to high volatility and increasing prices for crude oil, natural gas and other energy supplies. In the event that the supply of natural gas from Russia stops or is significantly reduced, there may be supply disruptions, increased prices or rationing of energy supply within countries in which we do business which could have a material adverse impact on our business or results of operations in those countries.

We are dependent on third-party freight carriers to transport many of our products. Our access to third-party freight carriers is not guaranteed, and we may be unable to transport our products at economically attractive rates in certain circumstances, particularly during disruptions to transportation infrastructure. Our business, financial position, results of operations or cash flows could be materially and adversely affected if we are unable to pass all of the cost increases on to our customers, or if freight carrier capacity in our geographic markets were to decline significantly or otherwise become unavailable.

We have supply agreements with Dow for ethylene, benzene, butadiene, and MMA, which are critical raw materials to our business. These raw materials and other less critical materials amount to approximately 22% of our total raw materials acquired in 2021, based on aggregate purchase price. The remainder is purchased via other third-party suppliers on a global basis. As these and other third-party supply agreements expire, we may be unable to renegotiate or renew these contracts, or obtain new long-term supply agreements on terms comparable or favorable to us, or at all, which may significantly impact our operations. See Part 1, Item 1—Business— Sources and Availability of Raw Materials of our Annual Report for the year ended December 31, 2021 for additional information.

If the availability of any of our principal raw materials is limited, we may be unable to produce some of our products in the quantities demanded by our customers, which could have an adverse effect on plant utilization and our sales of products requiring such raw materials. Suppliers may have temporary limitations preventing them from meeting our requirements, and we may not be able to obtain substitute alternative suppliers in a timely manner or on favorable terms.

Risks Related to Regulation

Trinseo Europe GmbH, one of our subsidiaries, received a Request for Information from the European Commission Directorate General for Competition, involving commercial activity for styrene monomer. To the extent the European Commission’s inquiry would lead to a finding that the Company’s subsidiary violated the law, the results of this finding could have a material adverse effect on our business, financial condition, results of operations, and cash flows.

On June 6, 2018, Trinseo Europe GmbH, a subsidiary of the Company, received a Request for Information in the form of a letter from the European Commission Directorate General for Competition (the “European Commission”) related to styrene monomer commercial activity in the European Economic Area. In addition, the Company commenced an internal investigation into the matter and has discovered instances of inappropriate activity. We have provided all information requested and continue to fully cooperate with the Request for Information.

As a result of further developments in this matter, during the three months ended March 31, 2022, the Company recorded a reserve for an estimated liability of $35.6 million, which remains ongoing and the outcome of which remains unknown. Trinseo Europe GmbH may be subject to fines and/or certain behavioral or structural commitments imposed by the European Commission. If Trinseo Europe GmbH is found to have violated one or more laws, it could also be subject to additional actions by local competition authorities. European Commission inquiries or investigations can continue over a long period of time, which can divert the attention of our management from day-to-day operations and impose significant administrative burdens. Any of these consequences could damage our reputation and impair our ability to conduct business, which could have a material adverse effect on our business, financial condition, results of operations, and cash flows.

TRINSEO EUROPE GMBH

AMENDED AND RESTATED EMPLOYMENT AGREEMENT

AMENDED AND RESTATED EMPLOYMENT AGREEMENT (this “Agreement”), dated as of October 1, 2021, is among Trinseo Europe GmbH, a Swiss limited liability company (Gesellschaft mit beschrӓnkter Haftung) (the “Company”), and Francesca Reverberi of Bremgartnerstrasse 15, 8003 Zurich, Switzerland (the “Executive”); which amends and restates the previous employment agreement entered into between the parties.

W I T N E S S E T H

WHEREAS, the Company desires to continue to employ the Executive as Senior Vice President, Chief Sustainability Officer and Synthetic Rubber of the Company and to pay all of the Executive’s compensation and other benefits described in this Agreement; and

WHEREAS, the Company and the Executive desire to update the terms and conditions of such employment by entering into this Agreement which shall define the terms of the Executive’s employment with the Company.

NOW, THEREFORE, in consideration of the foregoing, of the mutual promises con­tained herein and of other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto hereby agree as follows:

1.POSITION AND DUTIES.
(a)During the Employment Term (as defined in Section 2 hereof), the Executive shall serve as Senior Vice President, Chief Sustainability Officer and Synthetic Rubber of the Company and its ultimate parent company, Trinseo S.A. (“Parent”).  In this capacity, the Executive shall have the duties, authorities and responsibilities commensurate with the duties, authorities and responsibilities of persons in similar capacities in similarly sized companies, and such other executive duties, authorities and responsibilities as may reasonably be assigned to the Executive that are not inconsistent with the Executive’s position as Senior Vice President, Chief Sustainability Officer and Synthetic Rubber of the Company and the Parent. The Executive’s principal place of employment with the Company shall be in Horgen, Switzerland, or such other location in Switzerland within 75 kilometers from Horgen as the Company may designate. However, the Executive is aware and accepts that he/she will be required to travel frequently for business purposes. The Executive shall report directly to the President and Chief Executive Officer or a named executive officer of the Parent.
(b)During the Employment Term, the Executive shall devote all of the Executive’s business time, energy, business judgment, knowledge and skill and the Executive’s reasonable best efforts to the performance of the Executive’s duties with the Company and the Parent, provided that the foregoing shall not prevent the Executive from (i) serving on the boards of directors of non-profit organizations and, with the prior written approval of the Board of the Parent (the

1


“Board”), other for profit companies, (ii) participating in charitable, civic, educational, professional, community or industry affairs, and (iii) managing the Executive’s passive personal investments so long as such activities in the aggregate do not violate Section 10 hereof, interfere or conflict with the Executive’s duties hereunder or create a business or fiduciary conflict. Any overtime worked by the Executive is fully compensated by the Base Salary (as defined in Section 3).
2.EMPLOYMENT TERM. The Company agrees to employ the Executive pursuant to the terms of this Agreement commencing on the date written above (the “Effective Date”). Either party may terminate this Agreement by giving six months' advance written notice.  Notwithstanding the foregoing, the Executive’s employment hereunder may be earlier terminated in accordance with Section 6 hereof, subject to Section 7 hereof. The period of time between the Effective Date and the termination of the Executive’s employment hereunder shall be referred to herein as the “Employment Term.” No trial period shall apply to the employment.  This Agreement may be conditioned on any, or all of, the Executive: (i) passing a background check; (ii) passing a screening for illegal and controlled substances; and (iii) confirming employment eligibility; and (iv) providing the Company with the results of a recent physical examination or other evidence showing the absence of any conditions that would preclude the Executive from fulfilling the obligations contemplated in this Agreement.
3.BASE SALARY. During the Employment Term, the Company agrees to pay the Executive an annual base salary of not less than 450,000 CHF (Swiss francs) gross per annum, payable in accordance with the regular payroll practices of the Company, but not less frequently than monthly. The Executive’s base salary shall be subject to annual review by the Board (or a committee thereof) during the first ninety (90) days of each calendar year, and the base salary in respect of such calendar year may be increased above, but not decreased below, its level for the preceding calendar year, by the Board. The base salary as determined herein and adjusted from time to time shall constitute “Base Salary” for purposes of this Agreement.
4.ANNUAL BONUS.
(a)During the Employment Term, the Executive shall be eligible for an annual discretionary cash performance bonus (an “Annual Bonus”) in respect of each calendar year that ends during the Employment Term, to the extent earned based on performance against objective performance criteria. The performance criteria for any particular calendar year shall be determined in good faith by the Board, no later than ninety (90) days after the commencement of such calendar year. The Executive’s targeted Annual Bonus for a calendar year shall equal 50% of the Executive’s Base Salary for such calendar year (the “Target Bonus”) if target levels of performance for such year are achieved, with greater or lesser amounts (including zero) paid for performance above and below target (such greater and lesser amounts to be determined by a formula established by the Board for such year when it establishes the targets and performance criteria for such year); provided that the Executive’s maximum Annual Bonus for any calendar year during the Employment Term shall equal 200% of the Target Bonus for such calendar year.
(b)The Executive’s Annual Bonus for a calendar year shall be determined by, and is subject to the discretion of, the Board after the end of the applicable calendar year based on the level of achievement of the applicable performance criteria, and shall be paid to the Executive in

2


the calendar year following the calendar year to which such Annual Bonus relates at the same time annual bonuses are paid to other senior executives of the Company, subject to continued employment at the time of payment (except as otherwise provided in Section 7 hereof).
5.EMPLOYEE BENEFITS.
(a)BENEFIT PLANS. During the Employment Term, the Executive shall be entitled to participate in any employee benefit plan that the Company has adopted or may adopt, maintain or contribute to and which benefit any of the senior executives of the Company, on a basis no less favorable than that applicable to any such senior executives, subject to satisfying the applicable eligibility requirements, except to the extent such plans are duplicative of the benefits otherwise provided hereunder. The Executive’s participation in any such employee benefit plan shall be subject to the terms of the applicable plan documents and generally applicable Company policies. Notwithstanding the foregoing, the Company may modify or terminate any employee benefit plan at any time, if and to the extent allowed pursuant to the terms of such plan, provided that any such amendment may have no more adverse effect on the Executive than on any other participant in such plan.  The Company may provide perquisites to the Executive at the discretion of the Board.
(b)VACATIONS. During the Employment Term, the Executive shall be entitled to paid vacation in accordance with the Company’s policy on accrual and use applicable to employees as in effect from time to time, currently calculated as twenty-seven (27) days annually for the Executive.
(c)BUSINESS EXPENSES. Upon presentation of reasonable substantiation and documentation as the Company may specify from time to time, the Executive shall be reimbursed in accordance with the Company’s expense reimbursement policies as in effect from time to time, for all reasonable out-of-pocket business expenses incurred and paid by the Executive during the Employment Term and in connection with the performance of the Executive’s duties hereunder.
6.TERMINATION. Notwithstanding Section 2 above, the Executive’s employment and the Employment Term shall terminate on the first of the following to occur:
(a)DEATH. Automatically upon the date of death of the Executive.
(b)CAUSE. Immediately upon written notice by the Company to the Executive of a termination for cause ("wichtiger Grund") as provided for in Swiss employment law ("Cause").  For the sake of clarity, to the extent not already provided for in Swiss law, Cause shall also include the following behaviors: (i) continued failure to follow the lawful and reasonable directives of the Board after written notice from the Board and a period of no less than thirty (30) days to cure such failure; (ii) willful misconduct or gross negligence in the performance of the Executive’s duties; (iii) conviction of, or pleading of guilty or nolo contendere to, a non-vehicular felony; (iv) material violation of a material written Company or Parent policy that is not cured within fifteen (15) days of written notice from the Board; (v) performance of any material act of theft, embezzlement, fraud or misappropriation of or in respect of the Company’s property; (vi) continued failure to cooperate in any audit or investigation of financial or business practices of the Company or Parent after written request for cooperation from the Board and a period of no less than ten (10) days to cure such failure; (vii) commission of any criminal act or other act involving moral turpitude, sexual

3


harassment or drug violations (after an independent investigation concludes that such acts occurred and Executive has been presented with opportunity to participate in the investigation); (viii) commission of any willful act which brings public disrepute, contempt, scandal, or ridicule, or which shocks or offends the community or any group or class thereof, or which reflects unfavorably upon Company or Parent and, as a result of such act or involvement, reduces the commercial value of Company's or Parent’s association with Executive; (ix) willful actions (other than legal action or arbitration arising out of this Agreement) or making or authorizing statements in derogation of Company or Parent or their products and such actions or statements become public during the Term that result in damage to the business of the Company; or (x) breach of any of the restrictive covenants set forth in Section 10 hereof or in any other written agreement between the Executive and the Company and/or its Affiliate that causes material and demonstrable harm to the Company or Parent and that is not cured within fifteen (15) days of written notice from the Board.

For purposes of this Section 6(b), no act, or failure to act, on the part of the Executive shall be considered “willful” unless it is done, or omitted to be done, by the Executive in bad faith or without reasonable belief that the Executive’s action or omission was in the best interests of the Company.

7.CONSEQUENCES OF TERMINATION.
(a)DEATH. In the event that the Executive’s employment and the Employment Term ends on account of the Executive’s death, the Executive or the Executive’s estate, as the case may be, shall be entitled to the following (with the amounts due under Sections 7(a)(i) through 7(a)(v) hereof to be paid, unless otherwise provided below, within sixty (60) days following termination of employment, or such earlier date as may be required by applicable law):
(i)any unpaid Base Salary through the date of termination;
(ii)any Annual Bonus earned but unpaid with respect to the calendar year end­ing on or preceding the date of termination;
(iii)an amount equal to the pro-rata portion of the Executive’s Target Bonus for the calendar year of termination (determined by multiplying the Target Bonus for the year of termination by a fraction, the numerator of which is the number of days during the calendar year of termination that the Executive is employed by the Company and the denominator of which is 365);
(iv)reimbursement for any unreimbursed business expenses incurred through the date of termination;
(v)payment in respect of any accrued but unused vacation time in accordance with Company policy;
(vi)all other payments, benefits or fringe benefits to which the Executive shall be entitled under the terms of any applicable compensation arrangement or benefit, or fringe benefit plan or program or grant or this Agreement (collectively, Sections 7(a)(i) through 7(a)(vi) hereof shall be hereafter referred to as the “Accrued Benefits”) and

4


(vii)if the Executive is survived by a spouse, a registered partner, children who are minors or, in the absence of such heirs, other persons to whom he/she had a duty to provide support, the Base Salary for one month or, if the Executive had completed more than five years of service, for two months;
(b)TERMINATION FOR CAUSE BY THE COMPANY; TERMINATION BY THE EXECUTIVE. If the Executive’s employment is terminated (x) by the Company for Cause or (y) by the Executive for whatsoever reason, the Company shall pay to the Executive the Accrued Benefits; except for Section 7(a) (iii).  If the Executive terminates the Agreement, then the Company may elect to: (i) accelerate the Executive’s termination date which shall not be considered a termination by the Company without Cause; and (ii) transition Executive’s duties and responsibilities to others during the notice period.  However, in the event that the Executive terminates the Agreement and the Company elects to accelerate the Executive’s termination date, then the Executive will continue to receive Base Salary through the expiration of the notice period.
(c)TERMINATION WITHOUT CAUSE. If the Executive’s employment by the Company is terminated by the Company other than for Cause, the Company shall pay or provide the Executive with the following, subject to the provisions of Section 24 hereof:
(i)the Accrued Benefits;
(ii)subject to the Executive’s not engaging in a Material Covenant Violation as defined hereinafter or any other breach of Section 10 hereof that is not cured within fifteen (15) days of written notice from the Board (a “Material Cooperation Violation”), the Executive shall be entitled to an amount equal to one of the following (the applicable amount determined below to be referred to herein as the “Severance Amount”):

an amount equal to one and one-half (1.5) multiplied by the sum of the Executive’s then current annual Base Salary and Target Bonus for the year of termination, paid in equal monthly installments for a period of eighteen (18) months following such termination. Payments and benefits provided in this Section 7(c) shall be offset by Base Salary payments made during (i) any notice period as defined in Section 2 where the Executive has been relieved of responsibilities, and (ii) any monthly extension that corresponds to the number of months by which the notice period is extended based art. 336c CO, provided that the aggregate severance benefits payable hereunder shall be no less than as required by applicable law.

A “Material Covenant Violation” shall mean a breach of any of the restrictive covenants set forth in Section 10 hereof or in any other written agreement between the Executive and the Company and/or any of the Company’s or Parent’s direct or indirectly controlled subsidiaries (each an “Affiliate”) that causes material and demonstrable harm to the Company and/or any Affiliate.

(d)CHANGE IN CONTROL.
(i)This Section 7(d) shall apply if the Executive’s employment by the Com­pany is terminated (x) by the Company other than for Cause, or (y) by the Executive for good reason as defined in art. 340c para 2 CO, in either case, during the two (2)-year period commencing

5


upon a Change in Control. Subject to the Executive’s not engaging in a Material Covenant Violation or a Material Cooperation Violation, upon a termination described in the preceding sentence, the Executive shall receive the benefits set forth in Section 7(c) hereof, except that in lieu of receiving the Severance Amount in installments as contemplated under Section 7(c)(ii) hereof, the Executive shall receive a lump sum payment equal to the Severance Amount on the date of such termination.
(ii)For purposes of this Agreement, the term “Change in Control shall mean the consummation off the first transaction following the Effective Date, whether in a single transaction or in a series of related transactions, in which any individual, entity or group (within the meaning of Section 13(d)(3) or 14(d)(2) of the U.S. Securities Exchange Act of 1934, as amended) (A) acquires (whether by merger, consolidation, or transfer or issuance of equity interests or otherwise) equity interests of the Parent (or any surviving or resulting entity) representing more than fifty percent (50%) of the outstanding voting securities or economic value of the Parent (or any surviving or resulting entity), or (B) acquires assets constituting all or substantially all (more than eighty percent (80%)) of the assets of the Parent and its subsidiaries (as determined on a consolidated basis).
8.OTHER OBLIGATIONS. Upon any termination of the Executive’s employment with the Company and at any time before at the request of the Board, the Executive shall promptly resign from any other position as an officer, director or fiduciary of the Company, Parent and any Affiliate.
9.RELEASE; NO MITIGATION; NO SET-OFF. Any and all amounts payable and benefits or additional rights provided pursuant to this Agreement beyond the Accrued Benefits shall only be payable if the Executive signs and delivers to the Company a general release of claims in favor of the Company in substantially the form of Exhibit A attached hereto not earlier than 1 month and 1 day, but not later than 60 days after his employment has ended and does not revoke such General Release. In no event shall the Executive be obligated to seek other employment or take any other action by way of mitigation of the amounts payable to the Executive under any of the provisions of this Agreement, nor shall the amount of any payment hereunder be reduced by any compensation earned by the Executive as a result of employment by a subsequent employer. The Company’s obligations to pay the Executive amounts hereunder shall not be subject to set-off, counterclaim or recoupment of amounts owed by the Executive to the Company or any Affiliates.
10.RESTRICTIVE COVENANTS.
(a)CONFIDENTIALITY. During the course of the Executive’s employment with the Company, the Executive will learn confidential information regarding the Company. The Executive agrees that the Executive shall not, directly or indirectly, use, make available, sell, disclose or otherwise communicate to any person, other than in the course of the Executive’s assigned duties and for the benefit of the Company, either during the period of the Executive’s employment or at any time thereafter, any business and technical information or trade secrets, nonpublic, proprietary or confidential information, knowledge or data relating to the Company or any Affiliate, or received from third parties subject to a duty on the Company’s or any Affiliates’ part to maintain the confidentiality of such information and to use it only for certain limited

6


purposes, in each case which shall have been obtained by the Executive during the Executive’s employment by the Company. The foregoing shall not apply to information that (i) was known to the public prior to its disclosure to the Executive; (ii) becomes generally known to the public subsequent to disclosure to the Executive through no wrongful act of the Executive or any representative of the Executive; or (iii) the Executive is required to disclose by applicable law, regulation or legal process (provided that the Executive provides the Company with prior notice of the contemplated disclosure and cooperates with the Company at its expense in seeking a protective order or other appropriate protection of such information). The Executive shall keep the terms and conditions of this Agreement strictly confidential, and the Executive hereby agrees not to disclose the terms and conditions hereof to any person or entity, other than immediate family members, legal advisors or personal tax or financial advisors, or prospective future employers solely for the purpose of disclosing the limitations on the Executive’s conduct imposed by the provisions of this Section 10 who, in each case, shall be instructed by the Executive to keep such information confidential.
(b)NONCOMPETITION. The Executive acknowledges that the Executive performs services of a unique nature for the Company that are irreplaceable, and that the Executive’s performance of such services to a competing business will result in irreparable harm to the Company. Accordingly, during the Executive’s employment hereunder and for a period of twenty-four (24) months (this period referred to herein as the “Restricted Period”), the Executive agrees that the Executive will not, directly or indirectly, own, manage, operate, control, be employed by (whether as an employee, consultant, independent contractor or otherwise, and whether or not for compensation) or render services to any person, firm, corporation or other entity, in whatever form, engaged in competition with any material business of the Company or any Affiliate or in any other material business in which the Company or any Affiliate has taken material steps and has material plans, on or prior to the date or termination, to be engaged in on or after such date, in any locale of any country in which the Company or any Affiliate conducts business. Notwithstanding the foregoing, nothing herein shall prohibit the Executive from being a passive owner of not more than one percent (1%) of the equity securities of a publicly traded corporation engaged in a business that is in competition with the Company or any of its affiliates, so long as the Executive has no active participation in the business of such corporation.
(c)NONSOLICITATION; NONINTERFERENCE. During the Executive’s em­ployment with the Company and for the Restricted Period, the Executive agrees that the Executive shall not, except in the furtherance of the Executive’s duties hereunder, directly or indirectly, individually or on behalf of any other person, firm, corporation or other entity, (i) solicit, aid or induce any customer of the Company or an Affiliate to purchase goods or services then sold by the Company or any Affiliate from another person, firm, corporation or other entity or assist or aid any other persons or entity in identifying or soliciting any such customer, (ii) solicit, aid or induce any employee, representative or agent of the Company or any Affiliate to leave such employment or retention or, in the case of employees, to accept employment with or render services to or with any other person, firm, corporation or other entity unaffiliated with the Company or any Affiliate, or hire or retain any such employee, or take any action to materially assist or aid any other person, firm, corporation or other entity in identifying, hiring or soliciting any such employee, or (iii) interfere, or aid or induce any other person or entity in interfering, with the relationship between the Company or any Affiliate and any of their respective vendors, joint ventures or licensors. An employee, representative or agent shall be deemed covered by this Section 10(c) while so

7


employed or retained and for a period of six (6) months thereafter. Notwithstanding the foregoing, the provisions of this Section 10(c) shall not be violated by general advertising or solicitation not specifically targeted at Company or Affiliate-related individuals or entities.
(d)INTELLECTUAL PROPERTY RIGHTS. (i) The rights to inventions and de­signs made or conceived by the Executive individually or jointly while performing his employment activity and in performance of his contractual duties belong to the Company regardless of whether they are legally protected.
(ii) The rights to inventions and designs, made or conceived by the Executive while performing his employment activity, but not during the performance of his contractual duties, shall be assigned by the Executive to the Company as of their inception, regardless of whether they are legally protected. The Executive is obliged to inform the Company in writing of any such inventions or designs. The Company is entitled to grant the rights to these inventions and designs to the Executive. Should the Company retain such rights the Executive will be enti­tled to a special reasonable compensation.
(iii)Other rights to any work products and any know-how, which the Execu­tive creates or in which creation he participates while performing his employment activity belong exclusively to the Company. To the extent that work products (e.g., software, reports, documen­tations) are protected by copyrights, the Executive hereby assigns to the Company any and all rights related to such work products, particularly the copyright and any and all rights of use, in­cluding the rights of production and duplication, of publishing, to use, to license or to sell, to distribute over data or online media, to modify and develop further as well to develop new products on the basis of the work product of the Executive or on the basis of parts of such work product.
(e)RETURN OF COMPANY PROPERTY. On the date of the Executive’s termina­tion of employment with the Company for any reason (or at any time prior thereto at the Company’s request), the Executive shall return all property belonging to the Company or any Af­filiate (including, but not limited to, any Company-provided laptops, computers, cell phones, wireless electronic mail devices or other equipment, or documents and property belonging to the Company). Any retention right is excluded.
(f)REASONABLENESS OF COVENANTS. In signing this Agreement, the Execu­tive gives the Company assurance that the Executive has carefully read and considered all of the terms and conditions of this Agreement, including the restraints imposed under this Section 10. The Executive agrees that these restraints are necessary for the reasonable and proper protection of the Company and the Company and any Affiliate’s trade secrets and confidential information and that each and every one of the restraints is reasonable in respect to subject matter, length of time and geographic area, and that these restraints, individually or in the aggregate, will not pre­vent the Executive from obtaining other suitable employment during the period in which the Executive is bound by the restraints. The Executive acknowledges that each of these covenants has a unique, very substantial and immeasurable value to the Company and its Affiliates and that the Executive has sufficient assets and skills to provide a livelihood while such covenants remain in force. It is also agreed that the Affiliates will have the right to enforce all of the Executive’s obligations to such Affiliates under this Agreement, including without limitation pursuant to this Section 10.

8


(g)REFORMATION. If it is determined by a court of competent jurisdiction in any state that any restriction in this Section 10 is excessive in duration or scope or is unreasonable or unenforceable under applicable law, it is the intention of the parties that such restriction may be modified or amended by the court to render it enforceable to the maximum extent permitted by the laws of that state.
(h)SURVIVAL OF PROVISIONS. The obligations contained in Sections 10 and 11 hereof shall survive the termination or expiration of the Employment Term and the Executive’s employment with the Company and shall be fully enforceable thereafter.
11.COOPERATION. Upon the receipt of reasonable notice from the Company (in­cluding through outside counsel), the Executive agrees that while employed by the Company and thereafter (to the extent it does not materially interfere with the Executive’s employment or other business activities after employment by the Company), the Executive will respond and provide information with regard to matters in which the Executive has knowledge as a result of the Exec­utive’s employment with the Company, and will provide reasonable assistance to the Company, the Affiliates and their respective representatives in defense of all claims that may be made against the Company or the Affiliates, and will assist the Company and the Affiliates in the prosecution of all claims that may be made by the Company or the Affiliates, to the extent that such claims may relate to the period of the Executive’s employment with the Company. The Executive also agrees to promptly inform the Board (to the extent that the Executive is legally permitted to do so) if the Executive is asked to assist in any investigation of the Company or the Affiliates (or their actions), regardless of whether a lawsuit or other proceeding has then been filed against the Company or Affiliates with respect to such investigation, and shall not do so unless legally required. Upon presentation of appropriate documentation, the Company shall pay or reimburse the Executive for all reasonable out-of-pocket travel, duplicating, telephonic, counsel and other expenses incurred by the Executive in complying with this Section 11.
12.EQUITABLE RELIEF AND OTHER REMEDIES. The Executive acknowl­edges and agrees that the Company’s remedies at law for a breach or threatened breach of any of the provisions of Section 10 hereof or Section 11 hereof would be inadequate and, in recognition of this fact, the Executive agrees that, in the event of such a breach or threatened breach, in addition to any remedies at law, the Company shall be entitled to obtain equitable relief in the form of specific performance (Realerfüllung), a temporary restraining order, a temporary or permanent injunction or any other equitable remedy which may then be available. In the event of a Material Covenant Violation or a Material Cooperation Violation by the Executive, any severance being paid to the Executive pursuant to this Agreement or otherwise shall immediately cease unless otherwise prohibited by applicable law. In case of a breach by the Executive of any of the cove­nants contained in Section 10 or Section 11 hereof (i) any Severance Amount payable by the Com­pany, if any, shall be forfeited and (ii) the Executive shall pay to the Company a contractual penalty in an amount equal to (i) the Executive's last annual Base Salary for each individual breach of Sections 10(a), 10(b) and 10(c)(i), (ii) one twelfth (1/12th) of the Executive’s last annual Base salary for each individual breach of Sections 10(c)(ii), 10(c)(iii) and 11 and CHF 10,000 for each individual breach of Sections 10(e). In addition, the Executive shall have to compensate the Company for any damages and financial losses directly arising out of or relating to such breach. The Executive cannot disburden himself from the aforementioned prohibitions by the payment of the contractual penalty and/or damages.

9


13.NO ASSIGNMENTS. This Agreement is personal to each of the parties hereto. Ex­cept as provided in this Section 13 hereof, no party may assign or delegate any rights or obliga­tions hereunder without first obtaining the written consent of the other party hereto. The Company shall assign this Agreement to any successor to all or substantially all of the business and/or assets of the Company or Parent, provided that the Company shall require such successor to expressly assume and agree to perform this Agreement in the same manner and to the same extent that the Company would be required to perform it if no such succession had taken place, and provided that the Company agrees to perform such obligations if such successor fails to do so in a timely manner. As used in this Agreement, “Company” shall mean the Company and any successor to all or substantially all of its business and/or assets, which assumes and agrees to perform the duties and obligations of the Company under this Agreement by operation of law or otherwise.

16.SEVERABILITY.

17.SUPREMECY & COUNTERPARTS. This Agreement supersedes and replaces all prior agreements and understandings, whether oral or written, in connection with the subject matter hereof; including, but not limited to, the Employment Contract having an effective date of April 1, 2018.  This Agreement may be executed in several counterparts, each of which shall be deemed to be an original but all of which together will constitute one and the same instrument.
18.INDEMNIFICATION. The Company hereby agrees to indemnify the Executive and hold the Executive harmless to the fullest extent allowable under applicable law against and in respect of any and all actions, suits, proceedings, claims, demands, judgments, costs, expenses (including attorney’s fees, and the advancement of such fees subject to any legally required re­payment undertaking), losses, and damages resulting from the Executive’s performance of the Executive’s duties and obligations with the Company. This obligation shall survive the termination of the Executive’s employment with the Company.
19.LIABILITY INSURANCE. The Company shall cover the Executive under direc­tors’ and officers’ liability insurance both during and, while potential liability exists, after the Employment Term in the same amount and to the same extent as the Company covers its other officers and directors.
20.GOVERNING LAW. This Agreement, the rights and obligations of the parties hereto, and any claims or disputes relating thereto, shall exclusively be governed by and construed in accordance with the substantive laws of Switzerland.

22.MISCELLANEOUS.

No waiver by either party hereto at any time of any breach by the other party hereto of, or compliance with, any condition or provision of this Agreement to be performed by such other party shall be deemed a waiver of similar or dissimilar provisions or conditions at the same or at any prior or subsequent time. This Agreement together with all exhibits hereto sets forth the entire agreement of the parties hereto in respect of the subject matter contained herein and supersedes any and all prior agreements or understandings between the Executive and the Company with respect to the subject matter

11


hereof, whether written or oral. No agreements or representations, oral or otherwise, express or implied, with respect to the subject matter hereof have been made by either party which are not expressly set forth in this Agreement.
23.REPRESENTATIONS; ACTIONS BY PRIOR EMPLOYERS. The Executive represents and warrants to the Company that (a) the Executive has used the Executive’s best efforts to provide the Company with (i) each agreement with a predecessor employer which may have any bearing on the Executive’s legal right to enter into this Agreement and to perform all of the obligations on the Executive’s part to be performed hereunder in accordance with its terms, or (ii) a summary of the applicable provisions of each such agreement which the Executive may not provide to the Company due to an existing confidentiality obligation, and (b) other than the agreements referenced in the preceding clause (a), the Executive is not a party to any agreement or understanding, whether written or oral, and is not subject to any restriction (including, without limitation, any non-competition restriction from a prior employer), which, in either case, could prevent the Executive from entering into this Agreement or performing all of the Executive’s duties and obligations hereunder. The Executive understands that the foregoing representations are a material inducement to the Company entering into this Agreement, and to the extent that either of such representations is untrue in any material respect at any time or for any reason, this Agreement shall be voidable by the Company such that the parties hereunder shall be relieved of all of their respective duties and obligations hereunder; provided that any termination of the Ex­ecutive’s employment resulting from the Company exercising its rights pursuant to this sentence shall have the same consequences, especially financial consequences, as a termination of em­ployment by the Executive without good reason as defined in art. 340c para 2 CO. If any prior employer of the Executive, or any affiliate of any such prior employer, challenges the Executive’s right to enter into this Agreement and to perform all of the Executive’s obligations hereunder (whether by action against the Executive, the Company, Parent and/or an Affiliate), the Company (on behalf of itself, Parent and all Affiliates) and the Executive each agree to use their reasonable best efforts to defend against such challenge.
24.WITHHOLDING. The Company will deduct from the Employee's gross re­muneration as provided for in this Agreement the applicable Employee contributions, respectively premiums to social security schemes (AHV|IV, EO, ALV), the premiums for the pension fund (BVG), as well as applicable taxes, if any in accordance with the respective laws, regulations and plan documents.
25.FURTHER ASSURANCES. The parties hereto shall cooperate with each other and do, or procure the doing of, all acts and things, and execute, or procure the execution of, all documents, as may reasonably be required to give full effect to this Agreement.

EXHIBIT A

GENERAL RELEASE

I, CANDIDATE NAME, in consideration of and subject to the performance by Trinseo Europe GmbH. (together with its Affiliates, the “Company”), of its obligations under the Employment Agreement, dated as of [●] (the “Agreement”), do hereby release and forever discharge as of the date hereof the Company and its respective Affiliates and all present, former and future directors, officers, employees, successors and assigns of the Company and its Affiliates and direct or indirect owners (collectively, the “Released Parties”) to the extent provided below. The Released Parties are intended third-party beneficiaries of this General Release, and this General Release may be enforced by each of them in accordance with the terms hereof in respect of the rights granted to such Released Parties hereunder. Terms used herein but not otherwise defined shall have the meanings given to them in the Agreement.

1.I understand that any payments or benefits paid or granted to me under Section 7 of the Agreement represent, in part, consideration for signing this General Release and are not salary, wages or benefits to which I was already entitled. I understand and agree that I will not receive certain of the payments and benefits specified in Section 7 of the Agreement. Such payments and benefits will not be considered compensation for purposes of any employee benefit plan, program, policy or arrangement maintained or hereafter established by the Company or its affiliates.
2.Except as provided in paragraphs 1 above and 5 below and except for the provisions of the Agreement which expressly survive the termination of my employment with the Company, I knowingly and voluntarily (for myself, my heirs, executors, administrators and assigns) release and forever discharge the Company and the other Released Parties from any and all claims, suits, controversies, actions, causes of action, cross-claims, counter-claims, demands, debts, compensatory damages, liquidated damages, pu­nitive or exemplary damages, other damages, claims for costs and attorneys’ fees, or liabilities of any nature whatsoever in law and in equity, both past and present (through the date this General Release becomes effective and enforceable) and whether known or unknown, suspected, or claimed against the Company or any of the Released Parties which I, my spouse, or any of my heirs, executors, administrators or assigns, may have, which arise out of or are connected with my employment with, or my separation or termination from, the Company (all of the foregoing collectively referred to herein as the “Claims”).
3.I represent that I have made no assignment or transfer of any right, claim, demand, cause of action, or other matter covered by paragraph 2 above.
4.I agree that this General Release does not waive or release any rights or claims that I may have which arise after the date I execute this General Release. I acknowledge and agree that my separation from employment with the Company in compliance with the terms of the Agreement shall not serve as the basis for any claim or action.
5.I agree that I hereby waive all rights to sue or obtain equitable, remedial or punitive relief from any or all Released Parties of any kind whatsoever in respect of any Claim, including, without limitation, reinstatement, back pay, front pay, and any form of injunctive relief. Notwithstanding

A-1


the above, I further acknowledge that I am not waiving and am not being required to waive any right that cannot be waived under law at the time I sign this General Release, including the right to file an administrative charge or participate in an administrative investigation or proceeding; provided, however, that I disclaim and waive any right to share or participate in any monetary award resulting from the prosecution of such charge or investigation or proceeding. Additionally, I am not waiving any right to the Accrued Benefits or indemnity.
6.In signing this General Release, I acknowledge and intend that it shall be effective as a bar to each and every one of the Claims hereinabove mentioned or implied. I expressly consent that this General Release shall be given full force and effect according to each and all of its express terms and provisions, including those relating to unknown and unsuspected Claims (not­withstanding any state or local statute that expressly limits the effectiveness of a general release of unknown, unsuspected and unanticipated Claims), if any, as well as those relating to any other Claims hereinabove mentioned or implied. I acknowledge and agree that this waiver is an essential and material term of this General Release and that without such waiver the Company would not have agreed to the terms of the Agreement. I further agree that in the event I should bring a Claim seeking damages against the Company, or in the event I should seek to recover against the Company in any Claim brought by a governmental agency on my behalf, this General Release shall serve as a complete defense to such Claims to the maximum extent permitted by law. I further agree that I am not aware of any pending claim of the type described in paragraph 2 above as of the execution of this General Release.
7.I agree that neither this General Release, nor the furnishing of the consideration for this General Release, shall be deemed or construed at any time to be an admission by the Company, any Released Party or myself of any improper or unlawful conduct.
8.I agree that if I violate this General Release by suing the Company or the other Released Parties, I will pay all costs and expenses of defending against the suit incurred by the Released Parties, including reasonable attorneys’ fees.
9.I agree that this General Release and the Agreement are confidential and agree not to dis­close any information regarding the terms of this General Release or the Agreement, except to my immediate family and any tax, legal or other counsel I have consulted regarding the meaning or effect hereof or as required by law, and I will instruct each of the foregoing not to disclose the same to anyone. The Company agrees to disclose any such information only to any tax, legal or other counsel of the Company as required by law.

Exhibit 10.3

Trinseo PLC

Amended & Restated 2014 Omnibus Incentive Plan

Restricted Stock Unit Agreement

This agreement (this Agreement”) evidences an award (the Award”) of restricted stock units (the Restricted Stock Units”) granted by Trinseo PLC (the Company”) to the undersigned (the Grantee”) pursuant to the Trinseo PLC Amended and Restated 2014 Omnibus Incentive Plan (as amended from time to time, the “Plan”), which is incorporated herein by reference.

1.Grant of Restricted Stock Units. On the date of grant set forth above (the “Grant Date”) the Company granted to the Grantee an award consisting of the right to receive, on the terms provided herein and in the Plan, one share of Stock with respect to each Restricted Stock Unit forming part of the Award, in each case, subject to adjustment pursuant to Section 7 of the Plan in respect of transactions occurring after the date hereof.

The grant of the Restricted Stock Units is a one-time benefit and does not create any contractual or other right for the Grantee to receive a grant of restricted stock units or benefits in lieu of restricted stock units in the future.

The Award shall not be interpreted to bestow upon the Grantee any equity interest or ownership in the Company or any Affiliate prior to the date on which the Company delivers shares of Stock to the Grantee (if any). The Grantee is not entitled to vote any shares of Stock by reason of the granting of this Award or to receive or be credited with any dividends declared and payable on any share of Stock prior to the date on which any such share is delivered to the Grantee hereunder. The Grantee shall have the rights of a shareholder only as to those shares of Stock, if any, that are delivered under this Award.

2.Meaning of Certain Terms. Except as otherwise defined herein, all capitalized terms used herein have the same meaning as in the Plan.

3.Dividend Equivalents. During the period beginning on the Grant Date and ending on the date that shares of Stock are issued in settlement of vested Restricted Stock Units, the Grantee will accrue dividend equivalents on the Restricted Stock Units equal to any cash dividend or cash distribution that would have been paid on the Restricted Stock Unit had that Restricted Stock Unit been an issued and outstanding share of Stock on the record date for the dividend or distribution. Such accrued dividend equivalents (i) will vest and become payable upon the same terms and at the same time of settlement as the Restricted Stock Unit to which they relate (and will be payable with respect to any shares of Stock that are issued or that are withheld pursuant to Section 8 in order to satisfy Grantee’s Tax-Related Items), (ii) will be denominated and payable solely in cash and paid in such manner as the Company deems appropriate, and (iii) will not bear or accrue interest. Dividend equivalent payments, at settlement, will be net of applicable federal, state, local


and foreign income and social insurance withholding taxes as provided in Section 8. Upon the forfeiture of the Restricted Stock Units, any accrued dividend equivalents attributable to such Restricted Stock Units will also be forfeited.

4.Vesting, etc.

(a)The Award shall vest in full as to 100% of the Restricted Stock Units subject to the Award on the third anniversary of the Grant Date (“Vesting Date”), subject to the Grantee’s continued Employment with the Company through such date. Except as provided in sections (b) and (c) below, if the Grantee’s Employment with the Company terminates for any reason prior to the Vesting Date, the Award will be automatically and immediately forfeited upon such termination.

(b)If the Grantee’s Employment terminates due to his or her Retirement (as defined below), death, Permanent Disability, or due to a restructuring or redundancy, in each case, prior to any Vesting Date, the Award, to the extent then outstanding, will be treated as follows:

i.If the Grantee’s Employment terminates as a result of the Grantee’s Retirement (as defined below), following such termination the Award will continue to vest as if the Grantee had remained in continuous Employment through the Vesting Date. For purposes hereunder, “Retirement” means a retirement from active Employment after the Grantee has attained age 55 with at least 10 years of continuous service with the Company, or its predecessor entity, The Dow Chemical Company, or any of its subsidiaries, or as defined in the Grantee's employment or other agreement with the Company.

ii.If the Grantee’s Employment is terminated due to his or her death or by the Company due to his or her Permanent Disability, upon such termination, the Award will immediately vest in full as to the total number of Restricted Stock Units subject to the Award.

iii.If the Grantee’s Employment is terminated by the Company other than for Cause in connection with a restructuring or redundancy, as determined by the Company, upon such termination, the Award will vest in full as to the total number of Restricted Stock Units subject to the Award, and pursuant to the terms below. If the Grantee’s termination due to restructuring or redundancy occurs after the 12-month anniversary of the Grant Date, the Award will immediately vest in full. If the Grantee’s termination due to restructuring or redundancy occurs before the 12-month anniversary of the Grant Date and vesting is permitted according to the terms of the Plan, the Award will immediately vest in full, otherwise, the Award will immediately vest in full on the first day following the 12-month anniversary of the Grant Date. .

-2-


(c)If, within the twenty-four (24)-month period following the occurrence of a Change in Control (as defined below), (A) the Grantee’s Employment is terminated by the Company other than for Cause or, (B) if the Grantee is a current member of the Company’s executive leadership team and is subject to an effective employment or other individual agreement with the Company that provides the Grantee with the ability to terminate his or her employment for “good reason” (with such term having the meaning ascribed thereto in the employment or other individual agreement, if any, between the Grantee and the Company for so long as such agreement is in effect), upon such termination and in lieu of the treatment provided for in Section 4(b)(ii) above, the Award, to the extent then outstanding, will immediately vest in full as to the total number of Restricted Stock Units subject to the Award.

i.For purposes of this Agreement, “Change in Control” means the first to occur of any of the following events:

1.an event in which any “person,” as such term is used in Sections 13(d) and 14(d) of the U.S. Securities Exchange Act of 1934, as amended (the 1934 Act”) (other than (A) the Company, (B) any subsidiary of the Company, (C) any trustee or other fiduciary holding securities under an employee benefit plan of the Company or of any subsidiary of the Company, and (D) any company owned, directly or indirectly, by the stockholders of the Company in substantially the same proportions as their ownership of stock of the Company), is or becomes the “beneficial owner” (as defined in Section 13(d) of the 1934 Act), together with all affiliates and associates (as such terms are used in Rule 12b-2 of the General Rules and Regulations under the 1934 Act) of such person, directly or indirectly, of securities of the Company representing 40% or more of the combined voting power of the Company’s then outstanding securities;

2.the consummation of the merger or consolidation of the Company with any other company, other than (i) a merger or consolidation which would result in the voting securities of the Company outstanding immediately prior thereto continuing to represent (either by remaining outstanding or by being converted into voting securities of the surviving entity), in combination with the ownership of any trustee or other fiduciary holding securities under an employee benefit plan of the Company or any subsidiary of the Company, more than 50% of the combined voting power of the voting securities of the Company or such surviving entity outstanding immediately after such merger or consolidation and (ii) a merger or consolidation effected to implement a recapitalization of the Company (or similar

-3-


transaction) after which no “person” “beneficially owns” (with the determination of such “beneficial ownership” on the same basis as set forth in clause (1) of this definition) securities of the Company or the surviving entity of such merger or consolidation representing 50% or more of the combined voting power of the securities of the Company or the surviving entity of such merger or consolidation; or

3.the complete liquidation of the Company or the sale or disposition by the Company of all or substantially all of the Company’s assets.

Notwithstanding the foregoing, to the extent any amount constituting “nonqualified deferred compensation” subject to Section 409A would become payable under the Award by reason of a Change in Control, it shall become payable only if the event or circumstances constituting the Change in Control would also constitute a change in the ownership or effective control of the Company, or a change in the ownership of a substantial portion of the Company’s assets, within the meaning of subsection (a)(2)(A)(v) of Section 409A and the Treasury Regulations thereunder.

5.Delivery of Stock. Subject to Section 9(b), the Company shall, as soon as practicable upon the vesting of the Restricted Stock Units or any portion thereof as provided in Section 4(a), (b) or (c) of this Agreement (but in no event later than thirty (30) days following the date on which such Restricted Stock Units, or any portion thereof, vest) effect delivery of the Stock with respect to such vested Restricted Stock Units, or any portion thereof, to the Grantee (or, in the event of the Grantee’s death, to the Grantee’s beneficiary, which for purposes hereunder shall be (a) if permitted by the Administrator, the person(s) who has been designated by the Grantee in writing in a form and manner acceptable to the Administrator to receive the Award in the event of the Grantee’s death or (b) in the event no beneficiary designation has been made by the Grantee, the Grantee’s estate). No Stock will be issued pursuant to this Award unless and until all legal requirements applicable to the issuance or transfer of such Stock have been complied with to the satisfaction of the Administrator, including, for the avoidance of doubt to the extent required by Irish law, the payment by the Grantee to the Company of an amount in cash equal to the aggregate par value of the shares of Stock to be delivered in respect of the vested Restricted Stock Units on, or within thirty (30) days of, the vesting of the Restricted Stock Units. The actual amount the Grantee will be required to pay will be determined at the time that the Award vests based on the par value of the Company’s Stock on the final Vesting Date.

6.Forfeiture; Recovery of Compensation. By accepting the Award the Grantee expressly acknowledges and agrees that his or her rights (and those of any permitted transferee) under the Award or to any Stock acquired under the Award or any proceeds from the disposition thereof, are subject to Section 6(a)(5) of the Plan (including any successor provision). Nothing in the preceding sentence shall be construed as limiting the general application of Section 11 of this Agreement.

-4-


7.Nontransferability. Neither the Award nor the Restricted Stock Units may be transferred except at death in accordance with Section 6(a)(3) of the Plan.

8.Responsibility for Taxes & Withholding. Regardless of any action the Company or any of its Affiliates takes with respect to any or all income tax, social insurance, payroll tax, payment on account or other tax-related items related to the Grantee’s participation in the Plan and legally applicable to the Grantee (“Tax-Related Items”), the Grantee acknowledges that the ultimate liability for all Tax-Related Items is and remains the Grantee’s responsibility and may exceed the amount actually withheld by the Company or any of its Affiliates. The Grantee further acknowledges that the Company and/or its Affiliates (a) make no representations or undertakings regarding the treatment of any Tax-Related Items in connection with any aspect to the Restricted Stock Units, including, but not limited to, the grant, vesting or settlement of the Restricted Stock Units, the issuance of Stock upon settlement of the Restricted Stock Units, the subsequent sale of Stock acquired pursuant to such issuance and the receipt of any dividends and/or dividend equivalents; and (b) do not commit to and are under no obligation to structure the terms of any Award to reduce or eliminate Grantee’s liability for Tax-Related Items or achieve any particular tax result. Further, if the Grantee becomes subject to tax in more than one jurisdiction between the date of grant and the date of any relevant taxable event, the Grantee acknowledges that Company and/or its Affiliates may be required to withhold or account for Tax-Related Items in more than one jurisdiction.

Prior to any relevant taxable or tax withholding event, as applicable, the Grantee will pay or make adequate arrangements satisfactory to the Company and/or its Affiliates to satisfy all Tax-Related Items. In this regard, the Grantee authorizes the Company and/or its Affiliates, or their respective agents, at their discretion, to satisfy the obligations with regard to all Tax-Related Items by one or a combination of the following:

(i)withholding from the Grantee’s wages/salary or other cash compensation paid to the Grantee by the Company and/or its Affiliates; or

(ii)withholding from proceeds of the Stock acquired upon vesting/settlement of the Restricted Stock Units either through a voluntary sale or through a mandatory sale arranged by the Company (on Grantee’s behalf pursuant to this authorization); or

(iii)withholding in Stock to be issued upon vesting/settlement of the Restricted Stock Units provided, however, that if the Grantee is a Section 16 officer of the Company under the 1934 Act, then the Company will withhold in shares of Stock upon the relevant taxable or tax withholding event, as applicable, unless the use of such withholding method is problematic under applicable tax or securities law or has materially adverse accounting consequences, in which case, the obligation for Tax-Related Items may be satisfied by one or a combination of methods (i) and (ii) above.

To avoid negative accounting treatment, the Company and/or its Affiliates may withhold or account for Tax-Related Items by considering applicable minimum statutory withholding amounts or other applicable withholding rates. If the obligation for Tax- Related Items is satisfied by withholding in Stock, for tax purposes, the Grantee is deemed

-5-


to have been issued the full number of shares of Stock attributable to the vested Restricted Stock Units, notwithstanding that a number of share are held back solely for the purpose of paying the Tax-Related Items due as a result of any aspect of the Grantee’s participation in the Plan.

The Grantee shall pay to the Company and/or its Affiliates any amount of Tax- Related Items that the Company and/or its Affiliates may be required to withhold or account for as a result of the Grantee’s participation in the Plan that will not for any reason be satisfied by the means previously described. The Company may refuse to issue or deliver the Stock or the proceeds of the sale of Stock if the Grantee fails to comply with the Grantee’s obligations in connection with the Tax-Related Items.

By accepting this grant of Restricted Stock Units, the Grantee expressly consents to the methods of withholding Tax-Related Items by the Company and/or its Affiliates as set forth herein, including the withholding of Stock and the withholding from the Grantee's wages/salary or other amounts payable to the Grantee. All other Tax-Related Items related to the Restricted Stock Units and any Stock delivered in satisfaction thereof are the Grantee's sole responsibility.

9.Other Tax Matters.

(a)The Grantee expressly acknowledges that because this Award consists of an unfunded and unsecured promise by the Company to deliver Stock in the future, subject to the terms hereof, it is not possible to make a so-called “83(b) election” under U.S. federal tax laws with respect to the Award.

(b)If, at the time of the Grantee’s termination of employment, the Grantee is a “specified employee,” as defined below, to the extent required by Section 409A, any and all amounts payable on account of the Grantee’s separation from service that constitute deferred compensation and would (but for this provision) be payable within six (6) months following the date of termination, shall instead be paid on the next business day following the expiration of such six (6) month period or, if earlier, upon the Grantee’s death. For purposes of this Agreement, all references to “termination of employment” and correlative phrases shall be construed to require a “separation from service” (as defined in Treasury Regulations section 1.409A-1(h) after giving effect to the presumptions contained therein), and the term “specified employee” means an individual determined by the Company to be a specified employee under Treasury Regulation section 1.409A-1(i). Each payment made under this Agreement shall be treated as a separate payment and the right to a series of installment payments under this Agreement is to be treated as a right to a series of separate payments.

10.Effect on Employment. Neither the grant of the Restricted Stock Units, nor the delivery of Stock upon vesting of any portion thereof, will give the Grantee any right to be retained in the employ or service of the Company or any of its Affiliates, affect the right of the Company or any of its Affiliates to discharge or discipline such Grantee at any time, or affect any right of such Grantee to terminate his or her Employment at

-6-


any time.

11.Acknowledgements. By accepting the Award, the Grantee agrees to be bound by, and agrees that the Award and the Restricted Stock Units are subject in all respects to, the terms of the Plan. The Grantee further acknowledges and agrees that (i) this Agreement may be executed in two or more counterparts, each of which shall be an original and all of which together shall constitute one and the same instrument, (ii) this agreement may be executed and exchanged using facsimile, portable document format (PDF) or electronic signature, which, in each case, shall constitute an original signature for all purposes hereunder and (iii) such signature by the Company will be binding against the Company and will create a legally binding agreement when this Agreement is countersigned by the Grantee.

12.Authorization to Release and Transfer Necessary Personal Information. The Grantee hereby explicitly and unambiguously consents to the collection, use and transfer, in electronic or other form, of his or her personal data by and among, as applicable, the Company and the Affiliates for the exclusive purpose of implementing, administering and managing the Grantee’s participation in the Plan. The Grantee understands that the Company and the Affiliates may hold certain personal information about the Grantee including, but not limited to, the Grantee’s name, home address and telephone number, date of birth, social security number (or any other social or national identification number), salary, nationality, job title, number of Restricted Stock Units and/or Stock held and the details of all Restricted Stock Units or any other entitlement to Stock awarded, cancelled, vested, unvested or outstanding for the purpose of implementing, administering and managing the Grantee’s participation in the Plan (the “Data”). The Grantee understands that the Data may be transferred to the Company or any of the Affiliates, or to any third parties assisting in the implementation, administration and management of the Plan, that these recipients may be located in the Grantee’s country or elsewhere, and that any recipient’s country (e.g., the United States) may have different data privacy laws and protections than the Grantee’s country. The Grantee understands that he or she may request a list with the names and addresses of any potential recipients of the Data by contacting his or her local human resources representative. The Grantee authorizes the recipients to receive, possess, use, retain and transfer the Data, in electronic or other form, for the sole purpose of implementing, administering and managing his or her participation in the Plan, including any requisite transfer of such Data to a broker or other third party assisting with the administration of Restricted Stock Units under the Plan or with whom Stock acquired pursuant to the vesting of the Restricted Stock Units or cash from the sale of such Stock may be deposited. Furthermore, the Grantee acknowledges and understands that the transfer of the Data to the Company or the Affiliates or to any third parties is necessary for his or her participation in the Plan. The Grantee understands that Data will be held only as long as is necessary to implement, administer and manage his or her participation in the Plan. The Grantee understands that he or she may, at any time, view the Data, request additional information about the storage and processing of the Data, require any necessary amendments to the Data or refuse or withdraw the consents herein by contacting his or her local human resources representative in writing. The Grantee further acknowledges that withdrawal of consent may affect his or her ability to vest in or realize benefits from the Restricted Stock Units, and his or her ability to participate in the Plan. For more information on the consequences of refusal to consent or withdrawal of consent, the Grantee understands that he or she may contact his or her local human resources

-7-


representative.

Finally, upon request of the Company or the Grantee’s employer (the “Employer”), the Grantee agrees to provide an executed data privacy consent form (or any other agreements or consents that may be required by the Company and/or the Employer) that the Company and/or the Employer may deem necessary to obtain from the Grantee for the purpose of administering the Grantee’s participation in the Plan in compliance with the data privacy laws in the Grantee’s country, either now or in the future. The Grantee understands and agrees that the Grantee will not be able to participate in the Plan if the Grantee fails to provide any such consent or agreement requested by the Company and/or the Employer.

13.Electronic Delivery and Execution. The Grantee hereby consents and agrees to electronic delivery of any documents that the Company may elect to deliver (including, but not limited to, plan documents, prospectus and prospectus supplements, grant or award notifications and agreements, account statements, annual and quarterly reports, and all other forms of communications) in connection with this and any other Award made or offered under the Plan. The Grantee understands that, unless revoked by the Grantee by giving written notice to the Company pursuant to the Plan, this consent will be effective for the duration of the Agreement. The Grantee also understands that he or she will have the right at any time to request that the Company deliver written copies of any and all materials referred to above. The Grantee hereby consents to any and all procedures the Company has established or may establish for an electronic signature system for delivery and acceptance of any such documents that the Company may elect to deliver, and agree that his or her electronic signature is the same as, and will have the same force and effect as, his or her manual signature. The Grantee consents and agrees that any such procedures and delivery may be affected by a third party engaged by the Company to provide administrative services related to the Plan.

14.Appendix. Notwithstanding any provision of the Agreement to the contrary, this Restricted Stock Unit grant and the Stock acquired under the Plan shall be subject to any and all special terms and provisions as set forth in the Appendix, if any, for the Grantee’s country of residence (and country of employment, if different). Moreover, if the Grantee relocates to one of the countries included in the Appendix, the additional terms and conditions for such country will apply to the Grantee, to the extent the Company determines that the application of such terms and conditions is necessary or advisable for legal or administrative reasons.  The Appendix constitutes part of the Agreement.

15.Severability. The provisions of this Agreement are severable and if any one or more provisions are determined to be illegal or otherwise unenforceable, in whole or in part, the remaining provisions shall nevertheless be binding and enforceable.

COUNTRY APPENDIX

ADDITIONAL TERMS AND CONDITIONS TO RESTRICTED STOCK UNIT AGREEMENT

This Country Appendix (“Appendix”) includes the following additional terms and conditions that govern the Grantee’s Restricted Stock Unit Award for all the Grantees that reside and/or work outside of the United States.

Notifications

This Appendix also includes information regarding exchange controls and certain other issues of which the Grantee should be aware with respect to the Grantee’s participation in the Plan. The information is based on the securities, exchange control and other laws in effect in the respective countries as of January 2022. Such laws are often complex and change frequently. As a result, the Company strongly recommends that the Grantee not rely on the information in this Appendix as the only source of information relating to the consequences of the Grantee’s participation in the Plan because the information may be out of date at the time that the Restricted Stock Units vest, or Stock is delivered in settlement of the Restricted Stock Units, or the Grantee sells any Stock acquired under the Plan.

In addition, the information contained herein is general in nature and may not apply to the Grantee’s particular situation, and none of the Company, its Affiliates, nor the Administrator is in a position to assure the Grantee of a particular result. Accordingly, the Grantee is advised to seek appropriate professional advice as to how the relevant laws in the Grantee’s country of residence and/or work may apply to the Grantee’s situation.

Finally, if the Grantee transfers employment after the Grant Date, or is considered a resident of another country for local law purposes following the Grant Date, the notifications contained herein may not be applicable to the Grantee, and the Administrator shall, in its discretion, determine to what extent the terms and conditions contained herein shall be applicable to the Grantee.

Terms and Conditions Applicable to All Non-U.S. Jurisdictions

English Language. The Grantee acknowledges and agrees that it is the Grantee’s express intent that this Agreement, the Plan and all other documents, rules, procedures, forms, notices and legal proceedings entered into, given or instituted pursuant to the Restricted Stock Unit Award, be drawn up in English. If the Grantee has received this Agreement, the Plan or any other rules, procedures, forms or documents related to the Restricted Stock Unit Award translated into a language other than English, and if the meaning of the translated version is different than the English version, the English version will control.

Compliance with Law.  Notwithstanding any other provision of the Plan or this Agreement, unless there is an exemption from any registration, qualification or other legal requirement applicable to the Stock, the Company shall not be required to deliver any shares issuable upon settlement of the Restricted Stock Unit prior to the completion of any registration or qualification of the shares under any local, state, federal or foreign securities or exchange control law or under rulings or regulations of the U.S. Securities and Exchange Commission (“SEC”) or of any other

-10-


governmental regulatory body, or prior to obtaining any approval or other clearance from any local, state, federal or foreign governmental agency, which registration, qualification or approval the Company shall, in its absolute discretion, deem necessary or advisable. The Grantee understands that the Company is under no obligation to register or qualify the shares with the SEC or any state or foreign securities commission or to seek approval or clearance from any governmental authority for the issuance or sale of the shares.  Further, the Grantee agrees that the Company shall have unilateral authority to amend the Agreement without the Grantee’s consent to the extent necessary to comply with securities or other laws applicable to issuance of shares of Stock.

Insider Trading/Market Abuse.  The Grantee acknowledges that, depending on the Grantee’s or his or her broker's country or where the shares of Stock are listed, the Grantee may be subject to insider trading restrictions and/or market abuse laws which may affect the Grantee’s ability to accept, acquire, sell or otherwise dispose of shares of Stock, rights to shares of Stock (e.g., Restricted Stock Units) or rights linked to the value of shares of Stock (e.g., phantom awards, futures) during such times the Grantee is considered to have “inside information” regarding the Company as defined in the laws or regulations in the applicable jurisdictions).  Local insider trading laws and regulations may prohibit the cancellation or amendment of orders the Grantee placed before the Grantee possessed inside information.  Furthermore, the Grantee could be prohibited from (i) disclosing the inside information to any third party (other than on a “need to know” basis) and (ii) “tipping” third parties or causing them otherwise to buy or sell securities.  Keep in mind third parties includes fellow employees.  Any restrictions under these laws or regulations are separate from and in addition to any restrictions that may be imposed under any applicable insider trading policy of the Company.  The Grantee is responsible for complying with any restrictions and should speak to his or her personal advisor on this matter.

Exchange Control, Foreign Asset/Account and/or Tax Reporting.  Depending upon the country to which laws the Grantee is subject, the Grantee may have certain foreign asset/account and/or tax reporting requirements that may affect the Grantee’s ability to acquire or hold shares of Stock under the Plan or cash received from participating in the Plan (including from any dividends or dividend equivalents or sale proceeds arising from the sale of shares of Stock) in a brokerage or bank account outside the Grantee’s country of residence.  The Grantee’s country may require that the Grantee reports such accounts, assets or transactions to the applicable authorities in his or her country.  The Grantee also may be required to repatriate cash received from participating in the Plan to the Grantee’s country within a certain period of time after receipt.  The Grantee is responsible for knowledge of and compliance with any such regulations and should speak with his or her personal tax, legal and financial advisors regarding same.

Commercial Relationship. The Grantee expressly recognizes that the Grantee’s participation in the Plan and the Company’s Award grant does not constitute an employment relationship between the Grantee and the Company. The Grantee has been granted Restricted Stock Units as a consequence of the commercial relationship between the Company and the Employer, and the Employer is the Grantee’s sole employer. Based on the foregoing, (a) the Grantee expressly recognizes the Plan and the benefits the Grantee may derive from participation in the Plan do not establish any rights between the Grantee and the Affiliate that employs the Grantee, (b) the Plan and the benefits the Grantee may derive from participation in the Plan are not part of the employment conditions and/or benefits provided by the Affiliate that employs the Grantee, and (c) any modifications or amendments of the Plan by the Company or the Administrator, or a

-11-


termination of the Plan by the Company, shall not constitute a change or impairment of the terms and conditions of the Grantee’s employment with the Affiliate that employs the Grantee.

Private Placement. The grant of the Award is not intended to be a public offering of securities in the Grantee’s country of residence and/or employment but instead is intended to be a private placement. As a private placement, the Company has not submitted any registration statement, prospectus or other filings with the local securities authorities (unless otherwise required under local law), and the grant of the Restricted Stock Unit Award is not subject to the supervision of the local securities authorities.

Additional Acknowledgements. The GRANTEE also acknowledges and agrees to the following:

The Plan is established voluntarily by the Company, it is discretionary in nature, and it may be modified, amended, suspended or terminated by the Company at any time, to the extent permitted by the Plan.

All decisions with respect to future Awards or other grants, if any, will be at the sole discretion of the Company.

The future value of the underlying Stock is unknown, undeterminable and cannot be predicted with certainty.

The Award and the Stock subject to the Award, and the income and value of same, are not part of normal or expected compensation or salary for any purpose and are not intended to replace any pension rights or compensation.

The Grantee’s participation in the Plan is voluntary.

No claim or entitlement to compensation or damages arises from the forfeiture of the Award or any of the Restricted Stock Units, the termination of the Plan, or the diminution in value of the Restricted Stock Units or Stock, and the Grantee irrevocably releases the Company, its Affiliates, the Administrator and their affiliates from any such claim that may arise.

The Restricted Stock Unit and the Stock subject to the Restricted Stock Unit, and the income and value of same, are not part of normal or expected compensation for purposes of, including but not limited to, calculating any severance, resignation, termination, redundancy, dismissal, end-of-service payments, bonuses, holiday pay, long-service awards, pension or retirement or welfare benefits or similar payments.

Unless otherwise agreed with the Company in writing, the Award and the Stock subject to the Restricted Stock Unit, and the income and value of same, are not granted as consideration for, or in connection with, any service the Grantee may provide as a director of the Company or its Affiliates.

Neither the Company nor its Affiliates shall be liable for any foreign exchange rate fluctuation between the Grantee's local currency and the U.S. Dollar that may affect the value of the Restricted Stock Units or of any amounts due to the Grantee pursuant to the

-12-

The Company, with its address at 1000 Chesterbrook Boulevard, Suite 300, Berwyn, PA 19312, USA, is the controller responsible for the processing of the Grantee’s personal data by the Company and the third parties noted below, and its representative in Italy for privacy purposes is A.P.I. Applicazioni Plastiche Industriali S.p.A. with its registered address at Via Dante Alighieri n. 27, 36065 Mussolente (VI) Italy.

(a)Data Collection and Usage.

In granting the Restricted Stock Units under the Plan, the Company will collect Personal Data for purposes of allocating shares of Stock and implementing, administering and managing the Plan. The Company’s legal basis for the collection, processing and use of Personal Data is the necessity of the processing for the Company to perform its contractual obligations under the Agreement and the Plan and the Company’s legitimate business interests of managing the Plan, administering employee equity awards and complying with its contractual and statutory obligations.

(b)Stock Plan Administration Service Provider.

The Company’s service provider will open an account for the Grantee to receive and trade shares of Stock. The Grantee will be asked to agree on separate terms and data processing practices with the service provider, which is a condition to the Grantee’s ability to participate in the Plan.

Personal Data will only be accessible by those individuals requiring access to it for purposes of implementing, administering and operating the Plan.

(c)International Data Transfers. The Company and its service providers are based in the United States or elsewhere throughout the world. The Grantee’s country or jurisdiction may have different data privacy laws and protections than the United States. The Company's legal basis for the transfer of the Grantee’s Personal Data to the United States is to satisfy its contractual obligations under the terms and conditions of this Agreement.

-14-


(d)Data Retention. The Company will use Personal Data only as long as is necessary to implement, administer and manage the Grantee’s participation in the Plan or as required to comply with legal or regulatory obligations, including tax and securities laws. When the Company no longer needs Personal Data, the Company will remove it from its systems. If the Company keeps Personal Data longer, it would be to satisfy legal or regulatory obligations and the Company’s legal basis would be for compliance with relevant laws or regulations.

(e)Data Subject Rights. The Grantee may have a number of rights under data privacy laws in the Grantee’s country. For example, the Grantee’s rights may include the right to (i) request access or copies of Personal Data the Company processes, (ii) request rectification of incorrect Personal Data, (iii) request deletion of Personal Data, (iv) place restrictions on processing of Personal Data, (v) lodge complaints with competent authorities in the Grantee’s country, and/or (vi) request a list with the names and addresses of any potential recipients of Personal Data.

Annual Securities Account Tax Information.  An annual securities accounts tax may be payable if the total value of securities held in a Belgian or foreign securities account (e.g., shares acquired under the Plan) exceeds a certain threshold on four reference dates within the relevant reporting period (i.e., December 31, March 31, June 30 and September 30).  In such case, the tax will be due on the value of the qualifying securities held in such account.  The Grantee should consult with his or her personal tax advisor regarding the application of this tax.

SPAIN

Terms and Conditions

Nature of Award. In accepting the grant of Restricted Stock Units, the Grantee acknowledges that he or she consents to participation in the Plan and has received a copy of the Plan.

The Grantee understands that the Company has unilaterally, gratuitously and discretionally decided to grant Restricted Stock Units under the Plan to individuals who may be employees of the Company or its Affiliates throughout the world. The decision is a limited decision that is entered into upon the express assumption and condition that any grant will not economically or otherwise bind the Company or any of its Affiliates over and above the specific terms of the Plan. Consequently, the Grantee understands that the Restricted Stock Units are granted on the assumption and condition that the Restricted Stock Units and the Stock acquired upon lapse of the restrictions relating to the Restricted Stock Units shall not become a part of any employment contract (either with the Company or any of its Affiliates) and shall not be considered a mandatory benefit, salary for any purposes (including severance compensation) or any other right whatsoever.

Further, the Grantee understands and agrees that, unless otherwise expressly provided for by the Company or set forth in the Agreement, the Restricted Stock Units will be cancelled without entitlement to any Stock if the Grantee ceases to be an eligible participant for any reason, including, but not limited to: resignation, disciplinary dismissal adjudged to be with cause, disciplinary dismissal adjudged or recognized to be without good cause (i.e., subject to a “despido improcedente”), material modification of the terms of employment under Article 41 of the Workers’ Statute, relocation under Article 40 of the Workers’ Statute, Article 50 of the Workers’ Statute, or under Article 10.3 of Royal Decree 1382/1985.  The Company, in its sole discretion, shall determine the date when the Grantee’s status as an eligible participant has terminated for purposes of the Restricted Stock Units.

In addition, the Grantee understands that this grant would not be made to the Grantee but for the assumptions and conditions referred to above; thus, the Grantee acknowledges and freely accepts that should any or all of the assumptions be mistaken or should any of the conditions not be met for any reason, then any grant of Restricted Stock Units shall be null and void.

Securities Law Information. No “offer of securities to the public,” within the meaning of Spanish law, has taken place or will take place in the Spanish territory in connection with the Plan or Restricted Stock Unit.

registered with the Comisión Nacional del Mercado de Valores (the Spanish securities regulator), and none of those documents constitutes a public offering prospectus.

Exchange Control Information. In the event that the Grantee is a Spanish resident and acquires Stock under the Plan, he or she must declare such acquisition to the Spanish Dirección General de Comercio e Inversiones (the “DGCI”), the Bureau for Commerce and Investments, which is a department of the Ministry of Economy and Competitiveness.  If the Grantee acquires Stock through the use of a Spanish financial institution, the institution will automatically make the declaration with the DGCI for the Grantee.  The Grantee must also declare ownership or sale of any Stock by filing a Form D-6 with the Directorate of Foreign Transactions each January while the Stock is owned.  However, if the value of the Stock acquired or sold during the year exceeds the applicable threshold (currently €1,502,530), the filing is due within one month after the acquisition or sale, as applicable.

Spanish residents are required to electronically declare to the Bank of Spain any securities accounts (including brokerage accounts held abroad), as well as the securities (including Stock acquired at vesting of the Restricted Stock Units) held in such accounts, and any transactions carried out with non-residents, if the value of the transactions for all such accounts during the prior tax year or the balances in such accounts as of December 31 of the prior tax year exceeds €1,000,000.

Foreign Asset / Account Reporting Information.  Spanish residents holding rights or assets (e.g., Stock, cash, etc.) in a bank or brokerage account outside of Spain with a value in excess of €50,000 per type of right or asset as of December 31 each year are required to report information on such rights and assets on his or her tax return for such year.  Stock acquired under the Plan constitute securities for purposes of this requirement, but unvested rights (e.g., Restricted Stock Units) are not considered assets or rights for purposes of this requirement.  After such shares or accounts are initially reported, the reporting obligation will apply for subsequent years only if the value of any previously reported shares or accounts increases by more than €20,000 as of each subsequent December 31, or if the Grantee sells Stock or cancels bank accounts that were previously reported.

UNITED KINGDOM

Terms and Conditions

Tax Withholding and National Insurance Contributions Acknowledgement. Notwithstanding any provisions in the Agreement, the Grantee agrees that he or she is liable for all Tax-Related Items and hereby covenants to pay all such Tax-Related Items, as and when requested by the Company, the Employer, or by Her Majesty’s Revenue and Customs (“HMRC”) or any other tax authority or other relevant authority. The Grantee also agrees to indemnify and keep indemnified the Company and the Employer against any Tax-Related Items that they are required to pay or withhold, or have paid or will pay, to HMRC (or any other tax authority or other relevant authority) on the Grantee’s behalf.

Notwithstanding the foregoing, if the Grantee is a director or executive officer of the Company (within the meaning of Section 13(k) of the U.S. Securities Exchange Act of 1934, as amended), the terms of the immediately foregoing provision may not apply to the Grantee if the indemnification is viewed as a loan. In this case, if the amount of any income tax due is not collected from or paid by the Grantee within ninety (90) days of the end of the U.K. tax year in which an event giving rise to the indemnification described above occurs, the amount of any uncollected income tax may constitute an additional benefit to the Grantee on which additional income tax and national insurance contributions (“NICs”) may be payable. The Grantee will be responsible for reporting and paying any income tax due on this additional benefit directly to HMRC under the self-assessment regime and for paying to the Company or the Employer, as applicable, any employee NICs due on this additional benefit, which the Company or the Employer may recover from the Grantee by any of the means referred to in Section 8 of the Agreement.

-25-


Exclusion of Claim. The Grantee acknowledges and agrees that the Grantee will have no entitlement to compensation or damages insofar as such entitlement arises or may arise from the Grantee’s ceasing to have rights under or to be entitled to the Restricted Stock Units, whether or not as a result of termination of Grantee’s Employment (whether the termination is in breach of contract or otherwise), or from the loss or diminution in value of the Restricted Stock Units. Upon the grant of the Restricted Stock Units, the Grantee shall be deemed to have waived irrevocably any such entitlement.

The Stock Option evidenced by this Agreement is a non-statutory option (that is, an option that does not qualify as an incentive stock option under Section 422 of the Code) and is granted to the Optionee in connection with the Optionee’s employment by or service to the Company and its qualifying subsidiaries. For purposes of the immediately preceding sentence, “qualifying subsidiary” means a subsidiary of the Company as to which the Company has a “controlling interest” as described in Treas. Regs. §1.409A- 1(b)(5)(iii)(E)(1).

The grant of the Stock Option is a one-time benefit and does not create any contractual or other right for the Optionee to receive a grant of stock options or benefits in lieu of stock options in the future.

3.Vesting; Method of Exercise; Treatment of the Stock Option Upon Termination of Employment.

(a)Vesting. As used herein with respect to the Stock Option or any portion thereof, the term “vest” means to become exercisable and the term “vested” as applied to any outstanding Stock Option (or any portion thereof) means that the Stock Option is then exercisable, subject in each case to the terms of the Plan. Unless earlier terminated, forfeited, relinquished or expired, the Stock Option shall vest as to one-third (1/3) of the Shares subject to the Stock Option on each of the first, second and

-1-


third anniversaries of the Date of Grant (each, a “vesting anniversary date” and the third anniversary of the Date of Grant, the “final vesting anniversary date”). The number of Shares that vest on any of the foregoing dates will be rounded down to the nearest whole Share, with the Stock Option becoming vested as to 100% of the Shares on the final vesting anniversary date. Notwithstanding the foregoing, Shares subject to the Stock Option shall not vest on any vesting anniversary date unless the Optionee has remained in continuous Employment from the Date of Grant through such vesting anniversary date.

(b)Exercise of the Stock Option. No portion of the Stock Option may be exercised until such portion vests. Each election to exercise any vested portion of the Stock Option will be subject to the terms and conditions of the Plan and shall be in writing or by electronic notice, signed (including electronic signature in form acceptable to the Administrator) by the Optionee or a transferee (if permitted by the Administrator), if any (or in such other form as is acceptable to the Administrator). Each such exercise election must be received by the Company at its principal office or by such other party as the Administrator may prescribe and be accompanied by payment in full as provided in the Plan, including, for the avoidance of doubt to the extent required by Irish law, the payment by the Optionee to the Company of an additional amount in cash equal to the aggregate par value of the shares of Stock to be delivered in respect of the portion of the Stock Option so exercised at the time of the exercise of the Stock Option. The exercise price may be paid (i) by cash or check acceptable to the Administrator, (ii) to the extent permitted by the Administrator, through a broker-assisted cashless exercise program acceptable to the Administrator, (iii) by such other means, if any, as may be acceptable to the Administrator, or (iv) by any combination of the foregoing permissible forms of payment. In the event that the Stock Option is exercised by a person other than the Optionee, the Company will be under no obligation to deliver Shares hereunder unless and until it is satisfied as to the authority of such person to exercise the Stock Option and compliance with applicable securities laws. The latest date on which the Stock Option or any portion thereof may be exercised will be the 9th anniversary of the Date of Grant (the “Final Exercise Date”); provided, however, if at such time the Optionee is prohibited by applicable law or written Company policy applicable to similarly situated employees from engaging in any open-market sales of Stock, the Final Exercise Date will be automatically extended to thirty (30) days following the date the Optionee is no longer prohibited from engaging in such open-market sales. If the Stock Option is not exercised by the Final Exercise Date, the Stock Option or any remaining portion thereof will thereupon immediately terminate.

(c)Treatment of the Stock Option Upon Termination of Employment. Except as provided in clauses (i)-(iv) below and Section 3(d) of this Agreement, if the Optionee’s Employment terminates, the Stock Option, to the extent not already vested, will be immediately forfeited upon such termination. Following termination of the Optionee’s Employment, any vested portion

-2-


of the Stock Option that is then outstanding, including for the avoidance of doubt any portion of the Stock Option that vests as provided in clauses (ii)-(iv) below or Section 3(d) of this Agreement, will be treated as follows:

(i)General. Subject to clauses (ii) through (v) below and Sections 3(d) and 4 of this Agreement, the Stock Option, to the extent vested immediately prior to the termination of the Optionee’s Employment, will remain exercisable until the earlier of (A) the date that is three months following the date of such termination of Employment, or (B) the Final Exercise Date, and except to the extent previously exercised as permitted by this Section 3(c)(i) will thereupon immediately terminate.

(ii)Retirement. Subject to clause (v) below and Section 4 of this Agreement, if the Optionee’s Employment terminates due to the Optionee’s Retirement (as defined below), the Stock Option, to the extent then unvested, will not terminate and will remain outstanding and eligible to vest in accordance with the provisions of Section 3(a) hereof as if the Optionee had remained in continuous Employment through each vesting anniversary date. Any portion of the Stock Option that vests in accordance with this Section 3(c)(ii), together with the portion of the Stock Option, if any, that was vested as of immediately prior to the termination of the Optionee’s Employment due to the Optionee’s Retirement, will remain exercisable until the earlier of (A) five (5) years following the date of such termination of employment and, or (B) the Final Exercise Date, and except to the extent previously exercised as permitted by this Section 3(c)(ii) will thereupon immediately terminate. For purposes hereunder, “Retirement” means a retirement from active Employment after the Optionee has attained age fifty-five (55) with at least ten (10) years of continuous service with the Company, or its predecessor entity, The Dow Chemical Company, or any of its subsidiaries, or as defined in the Optionee’s employment or other agreement with the Company.

(iii)Death; Permanent Disability. Subject to clause (v) below and Section 4 of this Agreement, if the Optionee’s Employment is terminated due to his or her death or by the Company due to his or her Permanent Disability, the Stock Option, to the extent then unvested, shall immediately vest as to all of the then unvested Shares. Any portion of the Stock Option that vests in accordance with this Section 3(c)(iii), together with the portion of the Stock Option, if any, that was vested as of immediately prior to the termination of the Optionee’s Employment due to his or her death or by the Company due to his or her Permanent Disability, will remain exercisable until the earlier of (A) the first anniversary of the Optionee’s death or the first anniversary of the date the

-3-


Optionee’s Employment is terminated due to his or her Permanent Disability, as applicable or (B) the Final Exercise Date, and except to the extent previously exercised as permitted by this Section 3(c)(iii) will thereupon immediately terminate.

(iv)By the Company in Connection with Restructuring or Redundancy. Subject to clause (v) below and Sections 3(d) and 4 of this Agreement, if the Optionee’s Employment is terminated by the Company other than for Cause in connection with a restructuring or redundancy, as determined by the Company, the Stock Option, to the extent then unvested, will not terminate and will remain outstanding and eligible to vest in accordance with the provisions of Section 3(a) hereof as if the Optionee had remained in continuous Employment with the Company through each vesting anniversary date. Any Stock Option that vests in accordance with this Section 3(c)(iv), together with the portion of the Stock Option, if any, that was vested as of immediately prior to the termination of the Optionee’s Employment, will remain exercisable until the earlier of (A) the later of (i) three months following the date of such termination of employment and (ii) the date that is three months following the final vesting anniversary date or (B) the Final Exercise Date, and except to the extent previously exercised as permitted by this Section 3(c)(iv) will thereupon immediately terminate.
(v)For Cause.  If the Optionee’s Employment is terminated by the Company or its subsidiaries in connection with an act or failure to act constituting Cause (as the Administrator, in its sole discretion, may determine), or such termination occurs in circumstances that in the determination of the Administrator would have entitled the Company or its subsidiaries to terminate the Optionee’s Employment for Cause, the Stock Option (whether or not vested) will immediately terminate and be forfeited upon such termination.

(d)Treatment of the Stock Option Following a Change in Control. If, within the twenty-four (24)-month period following the occurrence of a Change in Control (as defined below), (A) the Optionee’s Employment is terminated by the Company other than for Cause or, (B) if the Optionee is a current member of the Company's executive leadership team and is subject to an effective employment or other individual agreement with the Company that provides the Optionee with the ability to terminate his or her employment for “good reason”, by the Optionee for “good reason” (with such term having the meaning ascribed thereto in the employment or other individual agreement, if any, between the Optionee and the Company for so long as such agreement is in effect), upon such termination and in lieu of the treatment provided for in Section 3(c)(iv) above, the Stock Option, to the extent then outstanding and unvested, shall immediately vest as to all of the then unvested Shares. Any Stock Option

-4-


that vests in accordance with this Section 3(d), together with the portion of the Stock Option, if any, that was vested as of immediately prior to the termination of the Optionee’s Employment, will remain exercisable until the earlier of (A) the date that is six months following the date of the Optionee’s termination of Employment, or (B) the Final Exercise Date, and except to the extent previously exercised as permitted by this Section 3(d) will thereupon immediately terminate.
(i)For purposes of this Agreement, “Change in Control” means the first to occur of any of the following events:

(A)an event in which any “person,” as such term is used in Sections 13(d) and 14(d) of the U.S. Securities Exchange Act of 1934, as amended (the “1934 Act”) (other than (I) the Company, (II) any subsidiary of the Company, (III) any trustee or other fiduciary holding securities under an employee benefit plan of the Company or of any subsidiary of the Company, and (IV) any company owned, directly or indirectly, by the stockholders of the Company in substantially the same proportions as their ownership of stock of the Company), is or becomes the “beneficial owner” (as defined in Section 13(d) of the 1934 Act), together with all affiliates and associates (as such terms are used in Rule 12b-2 of the General Rules and Regulations under the 1934 Act) of such person, directly or indirectly, of securities of the Company representing 40% or more of the combined voting power of the Company’s then outstanding securities;

(B)the consummation of the merger or consolidation of the Company with any other company, other than (i) a merger or consolidation which would result in the voting securities of the Company outstanding immediately prior thereto continuing to represent (either by remaining outstanding or by being converted into voting securities of the surviving entity), in combination with the ownership of any trustee or other fiduciary holding securities under an employee benefit plan of the Company or any subsidiary of the Company, more than 50% of the combined voting power of the voting securities of the Company or such surviving entity outstanding immediately after such merger or consolidation and (ii) a merger or consolidation effected to implement a recapitalization of the Company (or similar transaction) after which no “person” “beneficially owns” (with the determination of such “beneficial ownership” on the same basis as set forth in clause (A) of this definition) securities of the Company or the surviving entity of such merger or consolidation representing 50% or more of the combined voting power of the securities of the Company or the surviving entity of such merger or consolidation; or

-5-


(C)the complete liquidation of the Company or the sale or disposition by the Company of all or substantially all of the Company’s assets.

4.Forfeiture; Recovery of Compensation.

(a)The Administrator may cancel, rescind, withhold or otherwise limit or restrict the Stock Option at any time if the Optionee is not in compliance with all applicable provisions of this Agreement and the Plan.

(b)By accepting the Stock Option, the Optionee expressly acknowledges and agrees that his or her rights, and those of any transferee permitted by the Administrator of the Stock Option, under the Stock Option, including to any Stock acquired under the Stock Option or proceeds from the disposition thereof, are subject to Section 6(a)(5) of the Plan (including any successor provision). Nothing in the preceding sentence shall be construed as limiting the general application of Section 8 of this Agreement.

5.Transfer of Stock Option. The Stock Option may not be transferred except as expressly permitted under Section 6(a)(3) of the Plan.

6.Responsibility for Taxes & Withholding. Regardless of any action the Company or any of its Affiliates takes with respect to any or all income tax, social insurance, payroll tax, payment on account or other tax-related items related to the Optionee’s participation in the Plan and legally applicable to the Optionee (“Tax-Related Items”), the Optionee acknowledges that the ultimate liability for all Tax-Related Items is and remains the Optionee’s responsibility and may exceed the amount actually withheld by the Company or any of its Affiliates. The Optionee further acknowledges that the Company and/or its Affiliates (a) make no representations or undertakings regarding the treatment of any Tax-Related Items in connection with any aspect to the Stock Option, including, but not limited to, the grant, vesting or exercise of the Stock Option, the transfer of Stock upon exercise of the Stock Option, the subsequent sale of Shares acquired pursuant to such transfer and the receipt of any dividends; and (b) do not commit to and are under no obligation to structure the terms of any Award to reduce or eliminate Optionee’s liability for Tax-Related Items or achieve any particular tax result. Further, if the Optionee becomes subject to tax in more than one jurisdiction between the date of grant and the date of any relevant taxable event, the Optionee acknowledges that Company and/or its Affiliates may be required to withhold or account for Tax-Related Items in more than one jurisdiction.

Prior to any relevant taxable or tax withholding event, as applicable, the Optionee will pay or make adequate arrangements satisfactory to the Company and/or its Affiliates to satisfy all Tax-Related Items. In this regard, the Optionee authorizes the Company and/or its Affiliates, or their respective agents, at their discretion, to satisfy the obligations with regard to all Tax-Related Items by one or a combination of the following:

-6-


(i)withholding from the Optionee’s wages/salary or other cash compensation paid to the Optionee by the Company and/or its Affiliates; or

(ii)withholding from proceeds of the Shares acquired upon exercise of the Stock Option either through a voluntary sale or through a mandatory sale arranged by the Company (on Optionee's behalf pursuant to this authorization); or

(iii)withholding in Shares to be transferred upon exercise of the Stock Option provided, however, that if the Optionee is a Section 16 officer of the Company under the 1934 Act, then the Company will withhold in Shares upon the relevant taxable or tax withholding event, as applicable, unless the use of such withholding method is problematic under applicable tax or securities law or has materially adverse accounting consequences, in which case, the obligation for Tax- Related Items may be satisfied by one or a combination of methods (i) and (ii) above.

To avoid negative accounting treatment, the Company and/or its Affiliates may withhold or account for Tax-Related Items by considering applicable minimum statutory withholding amounts or other applicable withholding rates. If the obligation for Tax- Related Items is satisfied by withholding in Shares, for tax purposes, the Optionee is deemed to have been transferred the full number of Shares attributable to the Stock Option at exercise, notwithstanding that a number of share are held back solely for the purpose of paying the Tax-Related Items due as a result of any aspect of the Optionee’s participation in the Plan.

The Optionee shall pay to the Company and/or its Affiliates any amount of Tax- Related Items that the Company and/or its Affiliates may be required to withhold or account for as a result of the Optionee’s participation in the Plan that will not for any reason be satisfied by the means previously described. The Company may refuse to transfer the Shares or the proceeds of the sale of Shares if the Optionee fails to comply with the Optionee’s obligations in connection with the Tax-Related Items.

By accepting this grant of Stock Option, the Optionee expressly consents to the methods of withholding Tax-Related Items by the Company and/or its Affiliates as set forth herein, including the withholding of Shares and the withholding from the Optionee’s wages/salary or other amounts payable to the Optionee. All other Tax-Related Items related to the Stock Option and any Shares transferred in satisfaction thereof are the Optionee’s sole responsibility.

7.Effect on Employment. Neither the grant of the Stock Option, nor the issuance of Shares upon exercise of the Stock Option, will give the Optionee any right to be retained in the employ or service of the Company or any of its Affiliates, affect the right of the Company or any of its Affiliates to discharge or discipline such Optionee at any time, or affect any right of such Optionee to terminate his or her Employment at any time.

8.Provisions of the Plan. This Agreement is subject in its entirety to the provisions of the Plan, which are incorporated herein by reference. A copy of the Plan as in effect on the Date of Grant has been furnished to the Optionee. By acceptance of the Stock Option, the Optionee agrees to be bound by the terms of the Plan and this

-7-


Agreement. In the event of any conflict between the terms of this Agreement and the Plan, the terms of the Plan shall control.

9.Acknowledgements. The Optionee acknowledges and agrees that (i) this Agreement may be executed in two or more counterparts, each of which shall be an original and all of which together shall constitute one and the same instrument, (ii) this agreement may be executed and exchanged using facsimile, portable document format (PDF) or electronic signature, which, in each case, shall constitute an original signature for all purposes hereunder and (iii) such signature by the Company will be binding against the Company and will create a legally binding agreement when this Agreement is countersigned by the Optionee.

10.Authorization to Release and Transfer Necessary Personal Information. The Optionee hereby explicitly and unambiguously consents to the collection, use and transfer, in electronic or other form, of his or her personal data by and among, as applicable, the Company and the Affiliates for the exclusive purpose of implementing, administering and managing the Optionee’s participation in the Plan. The Optionee understands that the Company and the Affiliates may hold certain personal information about the Optionee including, but not limited to, the Optionee’s name, home address and telephone number, date of birth, social security number (or any other social or national identification number), salary, nationality, job title, number of Stock Options and/or Shares held and the details of all Stock Options or any other entitlement to Shares awarded, cancelled, vested, unvested or outstanding for the purpose of implementing, administering and managing the Optionee’s participation in the Plan (the “Data”). The Optionee understands that the Data may be transferred to the Company or any of the Affiliates, or to any third parties assisting in the implementation, administration and management of the Plan, that these recipients may be located in the Optionee’s country or elsewhere, and that any recipient’s country (e.g., the United States) may have different data privacy laws and protections than the Optionee’s country. The Optionee understands that he or she may request a list with the names and addresses of any potential recipients of the Data by contacting his or her local human resources representative. The Optionee authorizes the recipients to receive, possess, use, retain and transfer the Data, in electronic or other form, for the sole purpose of implementing, administering and managing his or her participation in the Plan, including any requisite transfer of such Data to a broker or other third party assisting with the administration of the Stock Option under the Plan or with whom Stock acquired pursuant to the exercise of the Stock Option or cash from the sale of such Stock may be deposited. Furthermore, the Optionee acknowledges and understands that the transfer of the Data to the Company or the Affiliates or to any third parties is necessary for his or her participation in the Plan. The Optionee understands that Data will be held only as long as is necessary to implement, administer and manage his or her participation in the Plan. The Optionee understands that he or she may, at any time, view the Data, request additional information about the storage and processing of the Data, require any necessary amendments to the Data or refuse or withdraw the consents herein by contacting his or her local human resources representative in writing. The Optionee further acknowledges that withdrawal of consent may affect his or her ability to vest in, exercise or realize benefits from the Stock Option, and his or her ability to participate in the Plan. For more information on the consequences of refusal to consent or withdrawal of consent, the Optionee understands that he or she may contact his or her local human resources representative.

Finally, upon request of the Company or the Optionee’s employer (the “Employer”), the Optionee agrees to provide an executed data privacy consent form (or any other agreements or consents that may be required by the Company and/or the Employer) that the Company and/or the Employer may deem necessary to obtain from the Optionee for the purpose of administering the Optionee’s participation in the Plan in compliance with the data privacy laws in the Optionee’s country, either now or in the future. The Optionee understands and agrees that the Optionee will not be able to participate in the Plan if the Optionee fails to provide any such consent or agreement requested by the Company and/or the Employer.

11.Electronic Delivery and Execution. The Optionee hereby consents and agrees to electronic delivery of any documents that the Company may elect to deliver (including, but not limited to, plan documents, prospectus and prospectus supplements, grant or award notifications and agreements, account statements, annual and quarterly reports, and all other forms of communications) in connection with this and any other Award made or offered under the Plan. The Optionee understands that, unless revoked by the Optionee by giving written notice to the Company pursuant to the Plan, this consent will be effective for the duration of the Agreement. The Optionee also understands that he or she will have the right at any time to request that the Company deliver written copies of any and all materials referred to above. The Optionee hereby consents to any and all procedures the Company has established or may establish for an electronic signature system for delivery and acceptance of any such documents that the Company may elect to deliver, and agree that his or her electronic signature is the same as, and will have the same force and effect as, his or her manual signature. The Optionee consents and agrees that any such procedures and delivery may be affected by a third party engaged by the Company to provide administrative services related to the Plan.

12.Appendix. Notwithstanding any provision of the Agreement to the contrary, this Stock Option grant and the Shares acquired under the Plan shall be subject to any and all special terms and provisions as set forth in the Appendix, if any, for the Optionee’s country of residence (and country of employment, if different). Moreover, if the Optionee relocates to one of the countries included in the Appendix, the additional terms and conditions for such country will apply to the Optionee, to the extent the Company determines that the application of such terms and conditions is necessary or advisable for legal or administrative reasons.  The Appendix constitutes part of the Agreement.

13.Severability. The provisions of this Agreement are severable and if any one or more provisions are determined to be illegal or otherwise unenforceable, in whole or in part, the remaining provisions shall nevertheless be binding and enforceable.

COUNTRY APPENDIX

ADDITIONAL TERMS AND CONDITIONS TO NON-STATUTORY STOCK OPTION AGREEMENT

This Country Appendix (“Appendix”) includes the following additional terms and conditions that govern the Optionee’s Stock Option for all Optionees that reside and/or work outside of the United States.

Notifications

This Appendix also includes information regarding exchange controls and certain other issues of which the Optionee should be aware with respect to the Optionee’s participation in the Plan. The information is based on the securities, exchange control and other laws in effect in the respective countries as of January 2022. Such laws are often complex and change frequently. As a result, the Company strongly recommends that the Optionee does not rely on the information in this Appendix as the only source of information relating to the consequences of the Optionee’s participation in the Plan, because the information may be out of date at the time that the Stock Option or portions thereof vest, or Shares are transferred upon exercise of the Stock Option, or the Optionee sells any Shares acquired under the Plan.

In addition, the information contained herein is general in nature and may not apply to the Optionee’s particular situation, and none of the Company, its Affiliates, nor the Administrator is in a position to assure the Optionee of a particular result. Accordingly, the Optionee is advised to seek appropriate professional advice as to how the relevant laws in the Optionee’s country of residence and/or work may apply to the Optionee’s situation.

Finally, if the Optionee transfers employment after the Grant Date, or is considered a resident of another country for local law purposes following the Grant Date, the notifications contained herein may not be applicable to the Optionee, and the Administrator shall, in its discretion, determine to what extent the terms and conditions contained herein shall be applicable to the Optionee.

Terms and Conditions Applicable to All Non-U.S. Jurisdictions

English Language. The Optionee acknowledges and agrees that it is the Optionee’s express intent that this Agreement, the Plan and all other documents, rules, procedures, forms, notices and legal proceedings entered into, given or instituted pursuant to the Stock Option, be drawn up in English. If the Optionee has received this Agreement, the Plan or any other rules, procedures, forms or documents related to the Stock Option translated into a language other than English, and if the meaning of the translated version is different than the English version, the English version will control.

Compliance with Law.  Notwithstanding any other provision of the Plan or this Agreement, unless there is an exemption from any registration, qualification or other legal requirement applicable to the Shares, the Company shall not be required to deliver any shares issuable upon exercise of the Stock Option prior to the completion of any registration or qualification of the shares under any local, state, federal or foreign securities or exchange control law or under

-11-


rulings or regulations of the U.S. Securities and Exchange Commission (“SEC”) or of any other governmental regulatory body, or prior to obtaining any approval or other clearance from any local, state, federal or foreign governmental agency, which registration, qualification or approval the Company shall, in its absolute discretion, deem necessary or advisable. The Optionee understands that the Company is under no obligation to register or qualify the shares with the SEC or any state or foreign securities commission or to seek approval or clearance from any governmental authority for the issuance or sale of the shares.  Further, the Optionee agrees that the Company shall have unilateral authority to amend the Agreement without the Optionee’s consent to the extent necessary to comply with securities or other laws applicable to issuance of Shares.

Insider Trading/Market Abuse.  The Optionee acknowledges that, depending on the Optionee’s or his or her broker's country or where the Shares are listed, the Optionee may be subject to insider trading restrictions and/or market abuse laws which may affect the Optionee’s ability to accept, acquire, sell or otherwise dispose of Shares, rights to Shares (e.g., Stock Options) or rights linked to the value of Shares (e.g., phantom awards, futures) during such times the Optionee is considered to have “inside information” regarding the Company as defined in the laws or regulations in the applicable jurisdictions).  Local insider trading laws and regulations may prohibit the cancellation or amendment of orders the Optionee placed before the Optionee possessed inside information.  Furthermore, the Optionee could be prohibited from (i) disclosing the inside information to any third party (other than on a “need to know” basis) and (ii) “tipping” third parties or causing them otherwise to buy or sell securities.  Keep in mind third parties includes fellow employees.  Any restrictions under these laws or regulations are separate from and in addition to any restrictions that may be imposed under any applicable insider trading policy of the Company.  The Optionee is responsible for complying with any restrictions and should speak to his or her personal advisor on this matter.

Exchange Control, Foreign Asset/Account and/or Tax Reporting.  Depending upon the country to which laws the Optionee is subject, the Optionee may have certain foreign asset/account and/or tax  reporting requirements that may affect the Optionee’s ability to acquire or hold Shares under the Plan or cash received from participating in the Plan (including from any dividends or dividend equivalents or sale proceeds arising from the sale of Shares) in a brokerage or bank account outside the Optionee’s country of residence.  The Optionee’s country may require that the Optionee reports such accounts, assets or transactions to the applicable authorities in his or her country.  The Optionee also may be required to repatriate cash received from participating in the Plan to the Optionee’s country within a certain period of time after receipt.  The Optionee is responsible for knowledge of and compliance with any such regulations and should speak with his or her personal tax, legal and financial advisors regarding same.

Commercial Relationship. The Optionee expressly recognizes that the Optionee’s participation in the Plan and the Company’s Stock Option grant does not constitute an employment relationship between the Optionee and the Company. The Optionee has been granted a Stock Option as a consequence of the commercial relationship between the Company and the Employer, and the Employer is the Optionee’s sole employer. Based on the foregoing, (a) the Optionee expressly recognizes the Plan and the benefits the Optionee may derive from participation in the Plan do not establish any rights between the Optionee and the Affiliate that employs the Optionee, (b) the Plan and the benefits the Optionee may derive from participation in the Plan are not part of the employment conditions and/or benefits provided by the Affiliate

-12-


that employs the Optionee, and (c) any modifications or amendments of the Plan by the Company or the Administrator, or a termination of the Plan by the Company, shall not constitute a change or impairment of the terms and conditions of the Optionee’s employment with the Affiliate that employs the Optionee.

Private Placement. The grant of the Stock Option is not intended to be a public offering of securities in the Optionee’s country of residence and/or employment but instead is intended to be a private placement. As a private placement, the Company has not submitted any registration statement, prospectus or other filings with the local securities authorities (unless otherwise required under local law), and the grant of the Stock Option is not subject to the supervision of the local securities authorities.

Additional Acknowledgements. The OPTIONEE also acknowledges and agrees to the following:

The Plan is established voluntarily by the Company, it is discretionary in nature, and it may be modified, amended, suspended, or terminated by the Company at any time, to the extent permitted by the Plan.

All decisions with respect to future Awards or other grants, if any, will be at the sole discretion of the Company.

The future value of the underlying Share is unknown, undeterminable and cannot be predicted with certainty.

If the underlying Share does not increase in value after the Date of Grant, the Stock Option will have no value.

If the Optionee exercises the Stock Option and acquire Shares, the value of such Shares may increase or decrease in value, even below the exercise price.
The Award and the Shares subject to the Award, and the income and value of same, are not part of normal or expected compensation or salary for any purpose and are not intended to replace any pension rights or compensation.

The Optionee's participation in the Plan is voluntary.
No claim or entitlement to compensation or damages arises from the forfeiture of the Award on the Stock Option, the termination of the Plan, or the diminution in value of the Stock Option or Shares, and the Optionee irrevocably releases the Company, its Affiliates, the Administrator and their affiliates from any such claim that may arise.

The Stock Option and the Share subject to the Stock Option, and the income and value of same, are not part of normal or expected compensation for purposes of, including but not limited to, calculating any severance, resignation, termination, redundancy, dismissal, end-of-service payments, bonuses, holiday pay, long-service awards, pension or retirement or welfare benefits or similar payments.

Unless otherwise agreed with the Company in writing, the Award and the Shares subject

-13-


to the Stock Option, and the income and value of same, are not granted as consideration for, or in connection with, any service the Optionee may provide as a director of the Company or its Affiliates.

Neither the Company nor its Affiliates shall be liable for any foreign exchange rate fluctuation between the Optionee's local currency and the U.S. Dollar that may affect the value of the Stock Option or Shares or of any amounts due to the Optionee pursuant to the settlement of the Stock Option or the subsequent sale of Shares acquired upon settlement.

None of the Company, its Affiliates, nor the Administrator is providing any tax, legal or financial advice or making any recommendations regarding the Optionee’s participation in the Plan, the grant, vesting or settlement of the Optionee’s Stock Option, or the Optionee’s acquisition or sale of the Shares transferred upon exercise of the Stock Option. The Optionee is hereby advised to consult with his own personal tax, legal and financial advisors regarding his participation in the Plan before taking any action related to the Plan.

The Company transfers Personal Data to Merrill Lynch and its affiliates, an independent service provider based in the United States, which assists the Company with the implementation, administration and management of the Plan. In the future, the Company may select a different service provider and share Personal Data with another company that serves in a similar manner. The Company’s service provider will open an account for the Optionee to receive and trade Shares. The Optionee will be asked to agree on separate terms and data processing practices with the service provider, which is a condition to the Optionee’s ability to participate in the Plan. The processing of Personal Data will take place through both electronic and non-electronic means. Personal Data will only be accessible by those individuals requiring access to it for purposes of implementing, administering and operating the Plan.

(c)International Data Transfers. The Company and its service providers are based in the United States or elsewhere throughout the world. The Optionee’s country or jurisdiction may have different data privacy laws and protections than the United States.

(d)Data Retention. The Company will use Personal Data only as long as is necessary to implement, administer and manage the Optionee’s participation in the Plan or as required to comply with legal or regulatory obligations, including tax and securities laws. When the Company no longer needs Personal Data, the Company will remove it from its systems. If the Company keeps Personal Data longer, it would be to satisfy legal or regulatory obligations and the Company’s legal basis would be for compliance with relevant laws or regulations.

(e)Data Subject Rights. The Optionee may have a number of rights under data privacy laws in the Optionee’s country. For example, the Optionee’s rights may include the right to (i) request access or copies of Personal Data the Company processes, (ii) request rectification of incorrect Personal Data, (iii) request deletion of Personal Data, (iv) place restrictions on processing of Personal Data, (v) lodge complaints with competent authorities in the Optionee’s country, and/or (vi) request a list with the names and addresses of any potential recipients of Personal Data.

Exhibit 10.5

TRINSEO PLC

Amended & Restated 2014 Omnibus Incentive Plan

Performance Award Stock Unit Agreement

This agreement (this “Agreement”) evidences an award (the “Award”) of restricted stock units subject to performance conditions (hereinafter referred to as Performance Award Stock Units or “PSUs”) granted by Trinseo PLC (the “Company”) to the undersigned (the “Grantee”) pursuant to the Trinseo PLC Amended & Restated 2014 Omnibus Incentive Plan (as amended from time to time, the “Plan”), which is incorporated herein by reference.

1.Grant of PSUs.  On the date of grant set forth above (the “Grant Date”) the Company granted to the Grantee an award consisting of the right to receive, on the terms provided herein and in the Plan and the performance conditions specified in Schedule A, one share of Stock with respect to each PSU forming part of the Award, in each case, subject to adjustment pursuant to Section 7 of the Plan in respect of transactions occurring after the date hereof.

The grant of the PSUs is a one-time benefit and does not create any contractual or other right for the Grantee to receive a grant of PSUs or benefits in lieu of PSUs in the future.

The Award shall not be interpreted to bestow upon the Grantee any equity interest or ownership in the Company or any Affiliate prior to the date on which the Company delivers shares of Stock to the Grantee (if any). The Grantee is not entitled to vote any shares of Stock by reason of the granting of this Award or to receive or be credited with any dividends declared and payable on any share of Stock prior to the date on which any such share is delivered to the Grantee hereunder.  The Grantee shall have the rights of a shareholder only as to those shares of Stock, if any, that are delivered under this Award.

2.Meaning of Certain Terms.  Except as otherwise defined herein, all capitalized terms used herein have the same meaning as in the Plan.  
3.Dividend Equivalents.  During the period beginning on the Grant Date and ending on the date that shares of Stock are issued in settlement of vested PSUs, the Grantee will accrue dividend equivalents on the PSUs (ultimately settled after adjustment for actual performance) equal to any cash dividend or cash distribution that would have been paid on the PSU had that PSU been an issued and outstanding share of Stock on the record date for the dividend or distribution. Such accrued dividend equivalents (i) will vest and become payable upon the same terms and at the same time of settlement as the PSU  to which they relate (and will be payable with respect to any shares of Stock that are issued or that are withheld pursuant to Section 9 in order to satisfy Grantee’s Tax-Related Items), (ii) will be denominated and payable solely in cash and paid in such manner as the Company deems appropriate, and (iii) will not bear or accrue interest. Dividend equivalent payments, at settlement, will be net of applicable federal, state, local and foreign income and social insurance withholding taxes as provided in Section 9. Upon the forfeiture of the PSUs, any accrued dividend equivalents attributable to such PSUs will also be forfeited.

-1-


4.Vesting, etc.  
(a)Except as otherwise provided in this section, both performance and service vesting requirements must be satisfied before the Grantee can vest in the PSUs. With certain exceptions noted below, the Grantee will vest in the PSUs under this Agreement only if the Grantee’s Employment continues through the third anniversary of the Grant Date (“Service Vesting Date”) and the Company achieves the performance targets specified in Schedule A. The number of PSUs that will vest will be equal to the number of Banked Units earned pursuant to Schedule A as of the Service Vesting Date. Except as provided in sections (b) and (c) below, if the Grantee’s Employment with the Company terminates for any reason prior to the Service Vesting Date, the Award will be automatically and immediately forfeited upon such termination. See Schedule 1 for an example of vesting of Banked Units.
(b)If the Grantee’s Employment terminates due to his or her Retirement (as defined below), death or Permanent Disability, in each case, prior to the Service Vesting Date, the Award, to the extent then outstanding, will be treated as follows:
i.If the Grantee’s Employment terminates as a result of the Grantee’s Retirement (as defined below), upon such termination, the Grantee will be deemed to have met the service vesting requirements under this Award and will be eligible to receive a number of PSUs equal to (X) multiplied by (Y), where: (X) equals the total number Banked Units to which the Grantee would be entitled based upon actual performance during each Performance Period as described in Schedule A, and (Y) is the ratio, the numerator of which is the number of full months occurring between the Grant Date and the date of Grantee’s Retirement, and the denominator of which is thirty-six (36). For purposes hereunder, “Retirement” means a retirement from active Employment after the Grantee has attained age 55 with at least 10 years of continuous service with the Company, or its predecessor entity, The Dow Chemical Company, or any of its subsidiaries, or as defined in the Grantee’s employment or other agreement with the Company.
ii.If the Grantee’s Employment is terminated due to his or her death or by the Company due to his or her Permanent Disability, upon such termination, the Grantee will be eligible to receive a number of PSUs equal to (X) multiplied by (Y), where: (X) equals the total number of Eligible Units to which the Grantee would be entitled based upon Target performance during each Performance Period as described in the performance matrix set forth in Schedule A, and (Y) is the ratio, the numerator of which is the number of full months occurring between the Grant Date and the date of Grantee’s death or date of termination due to Permanent Disability, and the denominator of which is thirty-six (36).
(c)If, within the twenty-four (24)-month period following the occurrence of a Change in Control (as defined below), the Grantee’s Employment is terminated by the Company other than for Cause or, if the Grantee is otherwise subject to an effective employment or other individual agreement with the Company that provides the Grantee with the ability to terminate his or her employment for “good reason,” by the Grantee for “good reason” (with such term having the meaning ascribed thereto in the employment or other individual agreement, if any, between the Grantee and the Company for so long as such agreement is in effect), upon such termination, the Award, to the extent then outstanding, and regardless of whether the award is to be settled in

-2-


shares of another entity, will result in truncated Performance Periods used to measure the performance criteria (to the extent measurable). The Performance Periods will be deemed to end on the effective date of the Change in Control and a determination of performance as provided in Schedule A will be made using the revised Performance Periods, though the amount determined for performance will at least equal the “Target” performance level for the truncated Performance Periods as set forth in the table in Schedule A.

For purposes of this Agreement, “Change in Control” means the first to occur of any of the following events:

i.an event in which any “person,” as such term is used in Sections 13(d) and 14(d) of the Securities Exchange Act of 1934 (the “1934 Act”) (other than (A) the Company, (B) any subsidiary of the Company, (C) any trustee or other fiduciary holding securities under an employee benefit plan of the Company or of any subsidiary of the Company, and (D) any company owned, directly or indirectly, by the stockholders of the Company in substantially the same proportions as their ownership of stock of the Company), is or becomes the “beneficial owner” (as defined in Section 13(d) of the 1934 Act), together with all affiliates and associates (as such terms are used in Rule 12b-2 of the General Rules and Regulations under the 1934 Act) of such person, directly or indirectly, of securities of the Company representing 40% or more of the combined voting power of the Company’s then outstanding securities;

ii.the consummation of the merger or consolidation of the Company with any other company, other than (i) a merger or consolidation which would result in the voting securities of the Company outstanding immediately prior thereto continuing to represent (either by remaining outstanding or by being converted into voting securities of the surviving entity), in combination with the ownership of any trustee or other fiduciary holding securities under an employee benefit plan of the Company or any subsidiary of the Company, more than 50% of the combined voting power of the voting securities of the Company or such surviving entity outstanding immediately after such merger or consolidation and (ii) a merger or consolidation effected to implement a recapitalization of the Company (or similar transaction) after which no “person” “beneficially owns” (with the determination of such “beneficial ownership” on the same basis as set forth in clause (1) of this definition) securities of the Company or the surviving entity of such merger or consolidation representing 50% or more of the combined voting power of the securities of the Company or the surviving entity of such merger or consolidation; or

iii.the complete liquidation of the Company or the sale or disposition by the Company of all or substantially all of the Company’s assets.

Notwithstanding the foregoing, to the extent any amount constituting “nonqualified deferred compensation” subject to Section 409A would become payable under the Award by reason of a Change in Control, it shall become payable only if the event or circumstances constituting the Change in Control would also constitute a change in the ownership or effective control of the Company, or a change in the ownership of a substantial portion of the Company’s assets, within the meaning of subsection (a)(2)(A)(v) of Section 409A and the Treasury Regulations thereunder.

-3-


5.Delivery of Stock.  Subject to Section 9(b), the Company shall, as soon as practicable following the vesting of the PSUs or any portion thereof as provided in Section 4(a), (b) or (c) of this Agreement (but in no event later than thirty (30) days following the date on which such PSUs, or any portion thereof, vest) effect delivery of the Stock with respect to such vested PSUs, or any portion thereof, to the Grantee (or, in the event of the Grantee’s death, to the Grantee’s beneficiary, which for purposes hereunder shall be (a) if permitted by the Administrator, the person(s) who has been designated by the Grantee in writing in a form and manner acceptable to the Administrator to receive the Award in the event of the Grantee’s death or (b) in the event no beneficiary designation has been made by the Grantee, the Grantee’s estate). No Stock will be issued pursuant to this Award unless and until the Compensation Committee completes the written certification set forth in Section 6 below and all legal requirements applicable to the issuance or transfer of such Stock have been complied with to the satisfaction of the Administrator, including, the for the avoidance of doubt to the extent required by Irish law, the payment by the Grantee to the Company of an amount in cash equal to the aggregate par value of the shares of Stock to be delivered in respect of the vested PSUs on, or within thirty (30) days of, the settlement of shares of Stock. The actual amount the Grantee will be required to pay will be determined at the time that the Award is settled with shares of Stock.
6.Forfeiture; Recovery of Compensation. By accepting the Award the Grantee expressly acknowledges and agrees that his or her rights (and those of any permitted transferee) under the Award or to any Stock acquired under the Award or any proceeds from the disposition thereof, are subject to Section 6(a)(5) of the Plan (including any successor provision).  Nothing in the preceding sentence shall be construed as limiting the general application of Section 11 of this Agreement.
7.Nontransferability.  Neither the Award nor the PSUs may be transferred except at death in accordance with Section 6(a)(3) of the Plan.
8.Responsibility for Taxes & Withholding.  Regardless of any action the Company or any of its Affiliates takes with respect to any or all income tax, social insurance, payroll tax, payment on account or other tax-related items related to the Grantee’s participation in the Plan and legally applicable to the Grantee (“Tax-Related Items”), the Grantee acknowledges that the ultimate liability for all Tax-Related Items is and remains the Grantee’s responsibility and may exceed the amount actually withheld by the Company or any of its Affiliates.  The Grantee further acknowledges that the Company and/or its Affiliates (a) make no representations or undertakings regarding the treatment of any Tax-Related Items in connection with any aspect to the PSUs, including, but not limited to, the grant, vesting or settlement of the PSUs, the issuance of Stock upon settlement of the PSUs, the subsequent sale of Stock acquired pursuant to such issuance and the receipt of any dividends and/or dividend equivalents; and (b) do not commit to and are under no obligation to structure the terms of any Award to reduce or eliminate Grantee’s liability for Tax-Related Items or achieve any particular tax result.  Further, if the Grantee becomes subject to tax in more than one jurisdiction between the date of grant and the date of any relevant taxable event, the Grantee acknowledges that Company and/or its Affiliates may be required to withhold or account for Tax-Related Items in more than one jurisdiction.

Prior to any relevant taxable or tax withholding event, as applicable, the Grantee will pay or make adequate arrangements satisfactory to the Company and/or its Affiliates to satisfy all Tax-Related Items.  In this regard, the Grantee authorizes the Company and/or its Affiliates, or their respective agents, at their discretion, to satisfy the obligations with regard to all Tax-Related Items by one or a combination of the following:

(i)withholding from the Grantee’s wages/salary or other cash compensation paid to the Grantee by the Company and/or its Affiliates; or

(ii) withholding from proceeds of the Stock acquired upon vesting/settlement of the PSUs either through a voluntary sale or through a mandatory sale arranged by the Company (on Grantee’s behalf pursuant to this authorization); or

(iii) withholding in Stock to be issued upon vesting/settlement of the PSUs provided, however, that if the Grantee is a Section 16 officer of the Company under the U.S. Securities and Exchange Act of 1934, as amended, then the Company will withhold in shares of Stock upon the relevant taxable or tax withholding event, as applicable, unless the use of such withholding method is problematic under applicable tax or securities law or has materially adverse accounting consequences, in which case, the obligation for Tax-Related Items may be satisfied by one or a combination of methods (i) and (ii) above.

To avoid negative accounting treatment, the Company and/or its Affiliates may withhold or account for Tax-Related Items by considering applicable minimum statutory withholding amounts or other applicable withholding rates.  If the obligation for Tax-Related Items is satisfied by withholding in Stock, for tax purposes, the Grantee is deemed to have been issued the full number of shares of Stock attributable to the vested PSUs, notwithstanding that a number of share are held back solely for the purpose of paying the Tax-Related Items due as a result of any aspect of the Grantee’s participation in the Plan.

The Grantee shall pay to the Company and/or its Affiliates any amount of Tax-Related Items that the Company and/or its Affiliates may be required to withhold or account for as a result of the Grantee’s participation in the Plan that will not for any reason be satisfied by the means previously described. The Company may refuse to issue or deliver the Stock or the proceeds of the sale of Stock if the Grantee fails to comply with the Grantee’s obligations in connection with the Tax-Related Items.

By accepting this grant of PSUs, the Grantee expressly consents to the methods of withholding Tax-Related Items by the Company and/or its Affiliates as set forth herein, including the withholding of Stock and the withholding from the Grantee’s wages/salary or other amounts payable to the Grantee.  All other Tax-Related Items related to the PSUs and any Stock delivered in satisfaction thereof are the Grantee’s sole responsibility.

9.Other Tax Matters.
(a)The Grantee expressly acknowledges that because this Award consists of an unfunded and unsecured promise by the Company to deliver Stock in the future, subject to the terms hereof, it is not possible to make a so-called “83(b) election” under U.S. federal tax laws with respect to the Award.
(b)If, at the time of the Grantee’s termination of employment, the Grantee is a “specified employee,” as defined below, to the extent required by Section 409A, any and all amounts payable on account of the Grantee’s separation from service that constitute deferred compensation and would (but for this provision) be payable within six (6) months following the date of termination, shall instead be paid on the next business day following the expiration of such six (6) month period or, if earlier, upon the Grantee’s death.  For purposes of this Agreement, all references to “termination of employment” and

-5-


correlative phrases shall be construed to require a “separation from service” (as defined in Treasury Regulations section 1.409A-1(h) after giving effect to the presumptions contained therein), and the term “specified employee” means an individual determined by the Company to be a specified employee under Treasury Regulation section 1.409A-1(i).  Each payment made under this Agreement shall be treated as a separate payment and the right to a series of installment payments under this Agreement is to be treated as a right to a series of separate payments.
10.Effect on Employment.  Neither the grant of the PSUs, nor the delivery of Stock upon vesting of any portion thereof, will give the Grantee any right to be retained in the employ or service of the Company or any of its Affiliates, affect the right of the Company or any of its Affiliates to discharge or discipline such Grantee at any time, or affect any right of such Grantee to terminate his or her Employment at any time.
11.Acknowledgements.  By accepting the Award, the Grantee agrees to be bound by, and agrees that the Award and the PSUs are subject in all respects to, the terms of the Plan.  The Grantee further acknowledges and agrees that (i) this Agreement may be executed in two or more counterparts, each of which shall be an original and all of which together shall constitute one and the same instrument, (ii) this agreement may be executed and exchanged using facsimile, portable document format (PDF) or electronic signature, which, in each case, shall constitute an original signature for all purposes hereunder and (iii) such signature by the Company will be binding against the Company and will create a legally binding agreement when this Agreement is countersigned by the Grantee.  
12.Authorization to Release and Transfer Necessary Personal Information. The Grantee hereby explicitly and unambiguously consents to the collection, use and transfer, in electronic or other form, of his or her personal data by and among, as applicable, the Company and the Affiliates for the exclusive purpose of implementing, administering and managing the Grantee’s participation in the Plan. The Grantee understands that the Company and the Affiliates may hold certain personal information about the Grantee including, but not limited to, the Grantee’s name, home address and telephone number, date of birth, social security number (or any other social or national identification number), salary, nationality, job title, number of PSUs and/or Stock held and the details of all PSUs or any other entitlement to Stock awarded, cancelled, vested, unvested or outstanding for the purpose of implementing, administering and managing the Grantee’s participation in the Plan (the “Data”).  The Grantee understands that the Data may be transferred to the Company or any of the Affiliates, or to any third parties assisting in the implementation, administration and management of the Plan, that these recipients may be located in the Grantee’s country or elsewhere, and that any recipient’s country (e.g., the United States) may have different data privacy laws and protections than the Grantee’s country.  The Grantee understands that he or she may request a list with the names and addresses of any potential recipients of the Data by contacting his or her local human resources representative.  The Grantee authorizes the recipients to receive, possess, use, retain and transfer the Data, in electronic or other form, for the sole purpose of implementing, administering and managing his or her participation in the Plan, including any requisite transfer of such Data to a broker or other third party assisting with the administration of PSUs under the Plan or with whom Stock acquired pursuant to the vesting of the PSUs or cash from the sale of such Stock may be deposited.  Furthermore, the Grantee acknowledges and understands that the transfer of the Data to the Company or the Affiliates or to any third parties is necessary for his or her participation in the Plan.  The Grantee understands that Data will be held only as long as is necessary to implement, administer and manage his or her participation in the Plan.  The Grantee understands that he or she may, at any time, view the Data, request additional information about the storage and processing of the Data, require any necessary amendments to the Data or refuse or

-6-


withdraw the consents herein by contacting his or her local human resources representative in writing.  The Grantee further acknowledges that withdrawal of consent may affect his or her ability to vest in or realize benefits from the PSUs, and his or her ability to participate in the Plan.  For more information on the consequences of refusal to consent or withdrawal of consent, the Grantee understands that he or she may contact his or her local human resources representative.

Finally, upon request of the Company or the Grantee’s employer (the “Employer”), the Grantee agrees to provide an executed data privacy consent form (or any other agreements or consents that may be required by the Company and/or the Employer) that the Company and/or the Employer may deem necessary to obtain from the Grantee for the purpose of administering the Grantee’s participation in the Plan in compliance with the data privacy laws in the Grantee’s country, either now or in the future. The Grantee understands and agrees that the Grantee will not be able to participate in the Plan if the Grantee fails to provide any such consent or agreement requested by the Company and/or the Employer.

13.Electronic Delivery and Execution.  The Grantee hereby consents and agrees to electronic delivery of any documents that the Company may elect to deliver (including, but not limited to, plan documents, prospectus and prospectus supplements, grant or award notifications and agreements, account statements, annual and quarterly reports, and all other forms of communications) in connection with this and any other Award made or offered under the Plan. The Grantee understands that, unless revoked by the Grantee by giving written notice to the Company pursuant to the Plan, this consent will be effective for the duration of the Agreement. The Grantee also understands that he or she will have the right at any time to request that the Company deliver written copies of any and all materials referred to above. The Grantee hereby consents to any and all procedures the Company has established or may establish for an electronic signature system for delivery and acceptance of any such documents that the Company may elect to deliver, and agree that his or her electronic signature is the same as, and will have the same force and effect as, his or her manual signature. The Grantee consents and agrees that any such procedures and delivery may be affected by a third party engaged by the Company to provide administrative services related to the Plan.
14.Appendix.  Notwithstanding any provision of the Agreement to the contrary, this PSU grant and the Stock acquired under the Plan shall be subject to any and all special terms and provisions as set forth in the Appendix, if any, for the Grantee’s country of residence (and country of employment, if different). Moreover, if the Grantee relocates to one of the countries included in the Appendix, the additional terms and conditions for such country will apply to the Grantee, to the extent the Company determines that the application of such terms and conditions is necessary or advisable for legal or administrative reasons. The Appendix constitutes part of the Agreement.
15.Severability.  The provisions of this Agreement are severable and if any one or more provisions are determined to be illegal or otherwise unenforceable, in whole or in part, the remaining provisions shall nevertheless be binding and enforceable.

Signature Page to Performance Stock Unit Agreement


SCHEDULE A

The number of PSUs to which the Grantee will be entitled if the Grantee satisfies the applicable service requirements will be calculated by the Committee (or sub-committee thereof) based on the Company’s “Relative Total Stockholder Return” (as defined below). Specifically, if the Grantee satisfies the applicable service requirements, the Committee shall calculate the number of Banked Units earned during each Performance Period by (x) multiplying the Grantee’s Target Number of PSUs by the applicable percentage set forth in each of section (a)-(d) below for each Performance Period (the “Eligible Units”), and (y) multiplying the number of Eligible Units by the applicable percentage determined as set forth below based on the Company’s Relative Total Stockholder Return results for the specified Performance Period. As noted in the Terms and Conditions to this Agreement, special rules apply under certain circumstances, such as death, Permanent Disability, Change in Control and Retirement.

For purposes of this Agreement, the term Banked Unit” means a PSU that has been tentatively credited for the Grantee’s benefit based on the Grantee’s service through a specified date and the satisfaction of applicable performance conditions as provided below, provided however, that a Banked Unit will not represent a vested PSU except to the extent provided in Section 4. Shares associated with vested PSUs shall only become deliverable, in accordance with Section 5.

For purposes of this Agreement, the term “Performance Period” shall mean the following periods, and Banked Units shall be calculated as follows:

(a)Calendar Year 2022. Subject to the Grantee’s continued Employment by the Company or any of its Affiliates through December 31, 2022, 15% of the Target Number of PSUs shall become Banked Units, subject to adjustment based upon the Company’s Total Stockholder Return (as defined below) relative to the Total Stockholder Return of the Comparator Group (as defined below) from January 1, 2022 until December 31, 2022 in accordance with the Relative Total Stockholder Return Table in Schedule A.
(b)Calendar Year 2023. Subject to the Grantee’s continued Employment by the Company or any of its Affiliates through December 31, 2023, 15% of the Target Number of PSUs shall become Banked Units, subject to adjustment based upon the Company’s Total Stockholder Return (as defined below) relative to the Total Stockholder Return of the Comparator Group (as defined below) from January 1, 2023 until December 31, 2023 in accordance with the Relative Total Stockholder Return Table in Schedule A.
(c)Calendar Year 2024. Subject to the Grantee’s continued Employment by the Company or any of its Affiliates through December 31, 2024, 15% of the Target Number of PSUs shall become Banked Units, subject to adjustment based upon the Company’s Total Stockholder Return (as defined below) relative to the Total Stockholder Return of the Comparator Group (as defined below) from January 1, 2024 until December 31, 2024 in accordance with the Relative Total Stockholder Return Table in Schedule A.
(d)Cumulative Period 2022–2024. Subject to the Grantee’s continued Employment by the Company or any of its Affiliates through December 31, 2024, 55% of the Target Number of PSUs shall become Banked Units, subject to adjustment based upon the Company’s Total Stockholder Return (as defined below) relative to the Total Stockholder Return of the Comparator Group (as


defined below) from January 1, 2022 until December 31, 2024 in accordance with the Relative Total Stockholder Return Table.

The following table shall apply for calculating this Award:

Relative Total Stockholder Return Over Each Performance Period

Performance Level

Payout Level (% of Target)

Relative TSR Ranking

Maximum*

200%

75th percentile

Target

100%

50th percentile

Threshold

50%

25th percentile

The maximum percentage by which the Grantee’s Target Number of PSUs is multiplied cannot exceed 200% and no PSUs shall become Banked Units unless the Company’s Relative Total Stockholder Return performance for the specified period is equal to or greater than the level required to earn an award of 50% of the Eligible Units for such period. Notwithstanding the above: (I) in the event that the Company’s Total Stockholder Return during any Performance Period is negative, the number of vested PSUs due to the Grantee cannot exceed 100% of the Grantee’s Eligible Units for such period, and (II) the fair market value of the total number of shares of Stock due to be delivered to the Grantee following the vesting of all Banked Units pursuant to Section 4 of the Agreement (determined on the certification date of the Award) shall not exceed 300% of the total fair market value of the shares of Stock attributable to the Eligible Units (determined as of the Grant Date).

If the Company’s Relative Total Stockholder Return performance falls between designated levels of performance set forth in the above table, the percentage by which the Grantee’s Eligible Units is multiplied will be calculated by linear interpolation.

Relative Total Stockholder Return shall mean the percentile ranking of the Company’s Total Stockholder Return (as defined below) measured relative to each company in the Comparator Group’s Comparator Total Stockholder Return (as defined below) during each Performance Period. The “Comparator Group” shall consist of all Chemical and Basic Materials companies in the S&P 600 Small Cap Index at the start of each Performance Period. Companies in the Comparator Group that are acquired during a Performance Period and are no longer publicly traded at the end of a Performance Period will be removed from the Comparator Group for such Performance Period. Any company in the Comparator Group which declares bankruptcy, is liquidated or is otherwise delisted during the relevant Performance Period shall remain in the Comparator Group and such company’s performance shall be considered to have been at the bottom of the Comparator Group. The Comparator Group companies for the initial Performance Period are set forth on the next page.

The percentile ranking of the Company’s Relative Total Stockholder Return shall be that fraction which is calculated by dividing the number of companies in the Comparator Group whose Comparator Total Stockholder Return performance is exceeded by the Company (based on the Total Stockholder Return) by the total number of companies in the Comparator Group.

Except as noted in this Schedule A, no adjustments for extraordinary items shall be made when calculating Relative Total Stockholder Return.


Total Stockholder Return shall mean the percentage rate of growth during each relevant Performance Period of an investment of $1,000 in shares of Stock on the first day of each such Performance Period, assuming reinvestment of all dividends paid during each such Performance Period and adjusted in an equitable manner for any material stock splits, reverse stock splits or similar transactions.

Comparator Total Stockholder Return for an applicable company in the Comparator Group shall mean the percentage rate of growth during each relevant Performance Period of an investment of $1,000 in shares of the common stock of the applicable company in the Comparator Group on the first day of each Performance Period, assuming reinvestment of all dividends paid during each Performance Period and adjusted in an equitable manner for any material stock splits, reverse stock splits or similar transactions.

Total Stockholder Return for the Company or any applicable company in the Comparator Group shall be measured based on the average fair market value (“FMV”) of the applicable share of stock for the thirty (30) trading days following the commencement of the Performance Period as compared to the average FMV of the same shares for the last thirty (30) trading days prior to the Service Vesting Date.  The FMV of the Company’s Stock or of a share of the common stock of a company in the Comparator Group shall mean the closing price of a share of that stock on the New York Stock Exchange or other national stock exchange on which that stock is actively traded for that date as reported in the Wall Street Journal, Eastern Edition or such other standard reference service as the Committee may select.

COUNTRY APPENDIX

ADDITIONAL TERMS AND CONDITIONS TO

PERFORMANCE AWARD STOCK UNIT AGREEMENT

This Country Appendix (“Appendix”) includes the following additional terms and conditions that govern the Grantee’s PSU Award for all Grantees that reside and/or work outside of the United States.

Notifications

This Appendix also includes information regarding exchange controls and certain other issues of which the Grantee should be aware with respect to the Grantee’s participation in the Plan. The information is based on the securities, exchange control and other laws in effect in the respective countries as of December 2021. Such laws are often complex and change frequently. As a result, the Company strongly recommends that the Grantee not rely on the information in this Appendix as the only source of information relating to the consequences of the Grantee’s participation in the Plan because the information may be out of date at the time that the PSUs vest, or Stock is delivered in settlement of the PSUs, or the Grantee sells any Stock acquired under the Plan.

In addition, the information contained herein is general in nature and may not apply to the Grantee’s particular situation, and none of the Company, its Affiliates, nor the Administrator is in a position to assure the Grantee of a particular result. Accordingly, the Grantee is advised to seek appropriate professional advice as to how the relevant laws in the Grantee’s country of residence and/or work may apply to the Grantee’s situation.

Finally, if the Grantee transfers employment after the Grant Date, or is considered a resident of another country for local law purposes following the Grant Date, the notifications contained herein may not be applicable to the Grantee, and the Administrator shall, in its discretion, determine to what extent the terms and conditions contained herein shall be applicable to the Grantee.

Terms and Conditions Applicable to All Non-U.S. Jurisdictions

English Language.  The Grantee acknowledges and agrees that it is the Grantee’s express intent that this Agreement, the Plan and all other documents, rules, procedures, forms, notices and legal proceedings entered into, given or instituted pursuant to the PSU Award, be drawn up in English. If the Grantee has received this Agreement, the Plan or any other rules, procedures, forms or documents related to the PSU Award translated into a language other than English, and if the meaning of the translated version is different than the English version, the English version will control.

Compliance with Law.  Notwithstanding any other provision of the Plan or this Agreement, unless there is an exemption from any registration, qualification or other legal requirement applicable to the Stock, the Company shall not be required to deliver any shares issuable upon settlement of the PSU prior to the completion of any registration or qualification of the shares under any local, state, federal or foreign securities or exchange control law or under rulings or regulations of the U.S. Securities and Exchange Commission (“SEC”) or of any other governmental regulatory body, or prior to obtaining any approval or other clearance from any local, state, federal or foreign governmental agency, which registration, qualification or approval the Company shall, in its absolute discretion, deem necessary or advisable. The Grantee understands that the Company is under no obligation to register or qualify the shares with the SEC or any state or foreign securities commission or to seek approval or clearance from any governmental authority for the issuance or sale of the shares.  Further, the Grantee agrees that the


Company shall have unilateral authority to amend the Agreement without the Grantee’s consent to the extent necessary to comply with securities or other laws applicable to issuance of shares of Stock.

Insider Trading/Market Abuse.  The Grantee acknowledges that, depending on the Grantee’s or his or her broker's country or where the shares of Stock are listed, the Grantee may be subject to insider trading restrictions and/or market abuse laws which may affect the Grantee’s ability to accept, acquire, sell or otherwise dispose of shares of Stock, rights to shares of Stock (e.g., PSUs) or rights linked to the value of shares of Stock (e.g., phantom awards, futures) during such times the Grantee is considered to have “inside information” regarding the Company as defined in the laws or regulations in the applicable jurisdictions).  Local insider trading laws and regulations may prohibit the cancellation or amendment of orders the Grantee placed before the Grantee possessed inside information.  Furthermore, the Grantee could be prohibited from (i) disclosing the inside information to any third party (other than on a “need to know” basis) and (ii) “tipping” third parties or causing them otherwise to buy or sell securities.  Keep in mind third parties includes fellow employees.  Any restrictions under these laws or regulations are separate from and in addition to any restrictions that may be imposed under any applicable insider trading policy of the Company.  The Grantee is responsible for complying with any restrictions and should speak to his or her personal advisor on this matter.

Exchange Control, Foreign Asset/Account and/or Tax Reporting.  Depending upon the country to which laws the Grantee is subject, the Grantee may have certain foreign asset/account and/or tax reporting requirements that may affect the Grantee’s ability to acquire or hold shares of Stock under the Plan or cash received from participating in the Plan (including from any dividends or dividend equivalents or sale proceeds arising from the sale of shares of Stock) in a brokerage or bank account outside the Grantee’s country of residence.  The Grantee’s country may require that the Grantee reports such accounts, assets or transactions to the applicable authorities in his or her country.  The Grantee also may be required to repatriate cash received from participating in the Plan to the Grantee’s country within a certain period of time after receipt.  The Grantee is responsible for knowledge of and compliance with any such regulations and should speak with his or her personal tax, legal and financial advisors regarding same.

Commercial Relationship.  The Grantee expressly recognizes that the Grantee’s participation in the Plan and the Company’s Award grant does not constitute an employment relationship between the Grantee and the Company. The Grantee has been granted PSUs as a consequence of the commercial relationship between the Company and the Employer, and the Employer is the Grantee’s sole employer. Based on the foregoing, (a) the Grantee expressly recognizes the Plan and the benefits the Grantee may derive from participation in the Plan do not establish any rights between the Grantee and the Affiliate that employs the Grantee, (b) the Plan and the benefits the Grantee may derive from participation in the Plan are not part of the employment conditions and/or benefits provided by the Affiliate that employs the Grantee, and (c) any modifications or amendments of the Plan by the Company or the Administrator, or a termination of the Plan by the Company, shall not constitute a change or impairment of the terms and conditions of the Grantee’s employment with the Affiliate that employs the Grantee.

Private Placement.  The grant of the Award is not intended to be a public offering of securities in the Grantee’s country of residence and/or employment but instead is intended to be a private placement. As a private placement, the Company has not submitted any registration statement, prospectus or other filings with the local securities authorities (unless otherwise required under local law), and the grant of the PSU Award is not subject to the supervision of the local securities authorities.


Additional Acknowledgements.  The GRANTEE also acknowledges and agrees to the following:

The Plan is established voluntarily by the Company, it is discretionary in nature, and it may be modified, amended, suspended or terminated by the Company at any time, to the extent permitted by the Plan.
All decisions with respect to future Awards or other grants, if any, will be at the sole discretion of the Company.
The future value of the underlying Stock is unknown, indeterminable and cannot be predicted with certainty.
The Award and the Stock subject to the Award, and the income and value of same, are not part of normal or expected compensation or salary for any purpose and are not intended to replace any pension rights or compensation.
The Grantee’s participation in the Plan is voluntary.
No claim or entitlement to compensation or damages arises from the forfeiture of the Award or any of the PSUs, the termination of the Plan, or the diminution in value of the PSUs or Stock, and the Grantee irrevocably releases the Company, its Affiliates, the Administrator and their affiliates from any such claim that may arise.
The PSU and the Stock subject to the PSU, and the income and value of same, are not part of normal or expected compensation for purposes of, including but not limited to, calculating any severance, resignation, termination, redundancy, dismissal, end of service payments, bonuses, holiday pay, long-service awards, pension or retirement or welfare benefits or similar payments.
Unless otherwise agreed with the Company in writing, the PSUs and the Stock subject to the PSUs, and the income and value of same, are not granted as consideration for, or in connection with, any service the Grantee may provide as a director of the Company or its Affiliates.
Neither the Company nor its Affiliates shall be liable for any foreign exchange rate fluctuation between the Grantee’s local currency and the U.S. Dollar that may affect the value of the PSUs or of any amounts due to the Grantee pursuant to the settlement of the PSUs or the subsequent sale of any Stock acquired upon settlement.
None of the Company, its Affiliates, nor the Administrator is providing any tax, legal or financial advice or making any recommendations regarding the Grantee’s participation in the Plan, the grant, vesting or settlement of the Grantee’s PSUs, or the Grantee’s acquisition or sale of the Stock delivered in settlement of the PSUs.

Terms and Conditions

Employee Data Privacy. The following provisions replace Section 12 of the Agreement in its entirety:

The Company, with its address at 1000 Chesterbrook Boulevard, Suite 300, Berwyn, PA 19312, USA, is the controller responsible for the processing of the Grantee’s personal data by the Company and the third parties noted below, and its representative in Italy for privacy purposes is A.P.I. Applicazioni Plastiche Industriali S.p.A. with its registered address at Via Dante Alighieri n. 27, 36065 Mussolente (VI) Italy.

(a)Data Collection and Usage. Pursuant to applicable data protection laws, the Grantee is hereby notified that the Company collects, processes and uses certain personally-identifiable information about the Grantee for the legitimate interest of implementing, administering and managing the Plan and generally administering equity awards; specifically, including the Grantee’s name, home address, email address and telephone number, date of birth, social insurance number or other identification number, salary, citizenship, job title, any shares of Stock or directorships held in the Company, and details of all Restricted Stock Units, any other entitlement to shares of Stock awarded, canceled, exercised, vested, or outstanding in the Grantee’s favor, which the Company receives from the Grantee or the Grantee’s employer (“Personal Data”). In granting the Restricted Stock Units under the Plan, the Company will collect Personal Data for purposes of allocating shares of Stock and implementing, administering and managing the Plan. The Company’s legal basis for the collection, processing and use of Personal Data is the necessity of the processing for the Company to perform its contractual obligations under the Agreement and the Plan and the Company’s legitimate business interests of managing the Plan, administering employee equity awards and complying with its contractual and statutory obligations.

(b)Stock Plan Administration Service Provider. The Company transfers Personal Data to Merrill Lynch and its affiliates, an independent service provider based in the United States, which assists the Company with the implementation, administration and management of the Plan.

The Company’s service provider will open an account for the Grantee to receive and trade shares of Stock. The Grantee will be asked to agree on separate terms and data processing practices with the service provider, which is a condition to the Grantee’s ability to participate in the Plan. The processing of Personal Data will take place through both electronic and non-electronic means. Personal Data will only be accessible by those individuals requiring access to it for purposes of implementing, administering and operating the Plan.

(c)International Data Transfers. The Company and its service providers are based in the United States or elsewhere throughout the world. The Grantee’s country or jurisdiction may have different data privacy laws and protections than the United States. The Company's legal basis for the transfer of the Grantee’s Personal Data to the United States is to satisfy its contractual obligations under the terms and conditions of this Agreement.

(d)Data Retention. The Company will use Personal Data only as long as is necessary to implement, administer and manage the Grantee’s participation in the Plan or as required to comply with legal or regulatory obligations, including tax and securities laws. When the Company no longer needs Personal Data, the Company will remove it from its systems. If the Company keeps Personal


Data longer, it would be to satisfy legal or regulatory obligations and the Company’s legal basis would be for compliance with relevant laws or regulations.

(e)Data Subject Rights. The Grantee may have a number of rights under data privacy laws in the Grantee’s country. For example, the Grantee’s rights may include the right to (i) request access or copies of Personal Data the Company processes, (ii) request rectification of incorrect Personal Data, (iii) request deletion of Personal Data, (iv) place restrictions on processing of Personal Data, (v) lodge complaints with competent authorities in the Grantee’s country, and/or (vi) request a list with the names and addresses of any potential recipients of Personal Data.
