**OWENS CORNING AND SUBSIDIARIES**

**NOTES TO CONSOLIDATED FINANCIAL STATEMENTS**

**(unaudited)**

**1.** **GENERAL**

*Unless the context requires otherwise, the terms "Owens Corning," "Company," "we" and "our" in these notes refer to Owens Corning and its subsidiaries.*

The Consolidated Financial Statements included in this report are unaudited, pursuant to certain rules and regulations of the Securities and Exchange Commission ("SEC"), and include, in the opinion of the Company, normal recurring adjustments necessary for a fair statement of the results for the periods indicated, which, however, are not necessarily indicative of results which may be expected for the full year. The December 31, 2025 balance sheet data was derived from audited financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States ("U.S."). In connection with the Consolidated Financial Statements and Notes included in this report, reference is made to the Consolidated Financial Statements and Notes contained in the Company's Annual Report on Form 10-K for the year ended December 31, 2025 (the "2025 Form 10-K"). Certain prior year amounts have been reclassified in order to conform to the current year presentation. On February 14, 2025, the Company announced the sale of its glass reinforcements ("GR") business. The transaction represented a strategic shift that has a major effect on the Company's operations and financial results and therefore, beginning with the quarterly report on Form 10-Q for the period ended March 31, 2025, and including this quarterly report on Form 10-Q for the period ended March 31, 2026, the GR financial results are reflected in the Company's consolidated financial statements as discontinued operations for all periods presented. Unless otherwise specified, these notes to the Consolidated Financial Statements reflect continuing operations. The Consolidated Statements of Cash Flows present cash flows from both continuing and discontinued operations. Please refer to Note 2 of the Consolidated Financial Statements for further information.

**<u>Revenue Recognition</u>**

As of March 31, 2026, our contract liability balances (for extended warranties, down payments and deposits, collectively) totaled $133 million. As of December 31, 2025, our contract liability balances totaled $133 million, of which $17 million was recognized as revenue in the three months ended March 31, 2026. As of December 31, 2024, our contract liability balances (for extended warranties, down payments and deposits, collectively) totaled $118 million, of which $12 million was recognized as revenue in the three months ended March 31, 2025.

**<u>Cash, Cash Equivalents and Restricted Cash</u>**

The Company defines cash and cash equivalents as cash and time deposits with maturities of three months or less when purchased. Restricted cash primarily represents amounts received from a counterparty related to its performance assurance on an executory contract, and is included in Other current assets on the Consolidated Balance Sheets. These amounts are contractually required to be set aside, and the counterparty can exchange the cash for another form of performance assurance at its discretion. Please refer to Note 16 for additional disclosures related to Supplemental Cash Flow Information.

**<u>Accounts Receivable</u>**

Our customers consist mainly of distributors, home centers, contractors and retailers. Two of our largest customers accounted for approximately 20% and 16%, respectively, of accounts receivable as of March 31, 2026.

**<u>Supplier Finance Programs</u>**

We review supplier terms and conditions on an ongoing basis, and have negotiated payment terms extensions in recent years in connection with our efforts to reduce working capital and improve cash flow. Separate from those terms extension actions, certain of our subsidiaries have entered into paying agency agreements with third-party administrators. These voluntary supply chain finance programs (collectively, the "Programs") generally give participating suppliers the ability to sell, or otherwise pledge as collateral, their receivables from the Company to the participating financial institutions, at the sole discretion of both the suppliers and financial institutions. The Company is not a party to the arrangements between the suppliers and the financial institutions. The Company's obligations to its suppliers, including amounts due and scheduled payment dates, are not impacted by the suppliers' decisions to sell, or otherwise pledge as collateral, amounts under these arrangements. The Company's payment terms to the financial institutions, including the timing and amount of payments, are based on the original supplier invoices. One of our Programs includes a parent guarantee to the participating financial institution for a certain U.S. subsidiary that, at the time of the respective program's inception in 2015, was a guarantor subsidiary of the Company's credit agreement. The obligations are presented as Accounts payable within Total current liabilities on the Consolidated Balance Sheets and all activity related to the obligations is presented within operating activities on the Consolidated Statements of Cash Flow.

**OWENS CORNING AND SUBSIDIARIES**

**NOTES TO CONSOLIDATED FINANCIAL STATEMENTS**

**(unaudited)**

The Company's confirmed outstanding obligations under the Programs totaled $168 million and $196 million as of March 31, 2026 and December 31, 2025, respectively. The amounts of invoices paid under the Programs totaled $155 million and $152 million for the three months ended March 31, 2026 and March 31, 2025, respectively.

**<u>Pension and Other Postretirement Benefits</u>**

The Company sponsors defined benefit pension plans. Under the plans, pension benefits are based on an employees' years of service and, for certain categories of employees, qualifying compensation. Company contributions to these pension plans are determined by an independent actuary to meet or exceed minimum funding requirements.

The Company maintains healthcare and life insurance benefit plans for certain retired employees and their dependents. The health care plans in the United States are non-funded and pay either (1) stated percentages of covered medically necessary expenses, after subtracting payments by Medicare or other providers and after stated deductibles have been met, or (2) fixed amounts of medical expense reimbursement.

Accounting for pensions and other postretirement benefits involves estimating the cost of benefits to be provided well into the future and attributing that cost over the time period each employee works. To accomplish this, extensive use is made of assumptions about investment returns, discount rates, inflation, mortality, turnover and medical costs.

**<u>Derivative Financial Instruments</u>**

The Company is exposed to commodity price, foreign currency exchange rate, and interest rate risks in the normal course of business. The Company's risk management program uses derivative financial instruments to manage a portion of the volatility associated with these exposures and does not enter into derivatives for trading purposes.

Derivatives designated as cash flow hedges are assessed for effectiveness quarterly. Changes in the fair value of effective cash flow hedges are recorded in Accumulated other comprehensive deficit ("AOCI") and reclassified into Cost of sales on the Consolidated Statements of Earnings in order to mirror the location of the hedged items impacting earnings. Cash settlements related to commodity cash flow hedges are included in Operating activities in the Consolidated Statements of Cash Flows.

The Company uses foreign exchange forward contracts to manage foreign currency risk associated with certain monetary assets and liabilities recorded on the Consolidated Balance Sheets. Gains and losses from the changes in the fair value of these instruments are recorded in Other (income) expense, net on the Consolidated Statements of Earnings, and are substantially offset by remeasurement impacts on the related foreign currency denominated balances. As of March 31, 2026, the Company had total notional amounts of $176 million for non-designated derivative financial instruments related to foreign currency exposures in U.S. Dollars primarily related to the Mexican Peso, Indian Rupee, Chinese Yuan, Hong Kong Dollar, South Korean Won, Brazilian Real, Chilean Peso and the Japanese Yen. In addition, the Company had notional amounts of $142 million for non-designated derivative financial instruments related to foreign currency exposures in European Euro primarily related to the Polish Złoty, Danish Krone and the Norwegian Krone.

In 2020, the Company entered into a $175 million forward U.S. Treasury rate lock agreement to manage the U.S. Treasury portion of its interest rate risk associated with anticipated debt issuance. The agreement was designated as a cash flow hedge and was settled in December 2022. Upon settlement, the Company received cash proceeds of $37 million, of which $31 million was deferred into AOCI and is being amortized to interest expense over the term of the Company's 5.700% senior notes due 2034. During the three months ended March 31, 2026, less than $1 million was recognized in interest expense related to amortization. As of March 31, 2026, $26 million of unrecognized gains related to the rate lock agreement remained in AOCI.

There have been no significant changes in the Company's objectives, strategies, or derivative programs since December 31, 2025. For a complete discussion of the Company's derivative instruments and hedging activities, see Note 5 of the Consolidated Financial Statements within our 2025 Form 10-K.

**<u>Related Party Transactions</u>**

In the first quarter of 2021, a related party relationship was established as a result of a former member of the Company's Board of Directors being named an executive officer of one of the Company's preexisting suppliers. The related party transactions with this supplier consist of the purchase of raw materials. Purchases from the related party supplier were $17 million and $25 million for the three months ended March 31, 2026 and 2025, respectively. As of March 31, 2026 and December 31, 2025, amounts due to the related party supplier were $6 million and $2 million, respectively.

**<u>Accounting Pronouncements</u>**

*New Pronouncements Adopted*

In July 2025, the Financial Accounting Standards Board ("FASB") issued **Accounting Standard Updates ("ASU") 2025-05, "Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets,"** which provides entities with a practical expedient when estimating expected credit losses for current accounts receivable and contract assets arising from transactions accounted for under ASC 606. The guidance is effective January 1, 2026. We have adopted and determined that this guidance did not have a material effect on our Consolidated Financial Statements.

*New Pronouncements Issued*

In December 2025, the FASB issued **ASU 2025-11, "Interim Reporting (Topic 270): Narrow-Scope Improvements,"** which improves the navigability and clarity of the interim reporting guidance. The guidance is effective January 1, 2028. We are currently assessing the impact adopting this standard will have on our Consolidated Financial Statement disclosures. We do not believe the adoption of this guidance will have a material effect on our results of operations.

In December 2025, the FASB issued **ASU 2025-10, "Government Grants (Topic 832): Accounting for Government Grants Received by Business Entities,"** which establishes recognition, measurement, and presentation guidance for government grants received by business entities. The guidance is effective January 1, 2029. We are currently assessing the impact adopting this standard will have on our Consolidated Financial Statement disclosures. We do not believe the adoption of this guidance will have a material effect on our results of operations.

In November 2025, the FASB issued **ASU 2025-09, "Derivatives and Hedging (Topic 815): Hedge Accounting Improvements,"** which enhances hedge accounting by aligning financial reporting more closely with actual economic risk management and introduces certain targeted refinements. The guidance is effective January 1, 2027. We are currently assessing the impact adopting this standard will have on our Consolidated Financial Statement disclosures. We do not believe the adoption of this guidance will have a material effect on our results of operations.

In September 2025, the FASB issued **ASU 2025-06, "Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software,"** which includes targeted improvements to recognition guidance for capitalizing software costs, replacing the previous stage-based model with a principles-based framework. The guidance is effective January 1, 2028. We are currently assessing the impact adopting this standard will have on our Consolidated Financial Statement disclosures. We do not believe the adoption of this guidance will have a material effect on our results of operations.

In November 2024, the FASB issued **ASU 2024-03, "Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40),"** which requires enhanced expense-category disclosures in the notes to the financial statements. In November 2024, the FASB issued **ASU 2025-01, "Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40),"** which clarifies the effective date of ASU 2024-03. The guidance is effective January 1, 2027 for the Company, with interim adoption beginning in 2028. The Company is currently assessing the impact adoption of this standard will have on its consolidated financial statement disclosures and does not believe adoption will have a material effect on its results of operations.

In October 2023, the FASB issued **ASU 2023-06, "Disclosure Improvements,"** which modifies the disclosure or presentation requirements for a variety of Topics. The effective date for each topic is contingent on future SEC rule setting. We are currently assessing the impact adopting this standard will have on our Consolidated Financial Statement disclosures. We do not believe the adoption of this guidance will have a material effect on our results of operations.

**2.** **DISCONTINUED OPERATIONS**

On February 13, 2025, the Company entered into a definitive agreement ("GR Agreement") for the sale of our GR business for a purchase price of approximately $436 million, less costs to sell. The GR business, historically part of the Company's Composites segment, manufactures, fabricates, and sells glass fiber reinforcements for a wide variety of applications in wind energy, infrastructure, industrial, transportation and consumer markets.

The transaction represented a strategic shift that has a major effect on the Company's operations and financial results and therefore, beginning with the quarterly report on Form 10-Q for the period ended March 31, 2025, GR's financial results are reflected in the Company's consolidated financial statements as discontinued operations for all periods presented.

**OWENS CORNING AND SUBSIDIARIES**

**NOTES TO CONSOLIDATED FINANCIAL STATEMENTS**

**(unaudited)**

As a result of classifying our GR business as a discontinued operation, a portion of the Goodwill from our former Composites reporting unit was allocated to the balance sheets of the discontinued operation. As of the date of classification of GR as a discontinued operation, the Company determined the amount of Goodwill to allocate based on the relative fair values of the discontinued operation and the former Composites reporting unit, which resulted in an allocation of Goodwill to the discontinued operation of $98 million as of the held for sale date.

On April 14, 2026, the Company entered into an amendment to the GR Agreement ("Amendment") to address changing market conditions. The Amendment includes a $110 million decrease in the purchase price, the transfer of approximately $32 million in carrying value of additional assets at close and elimination of the $225 million promissory notes that were to be issued to the Company by the purchasers. As of March 31, 2026, the estimated purchase price was $413 million, net of cash, less costs to sell. The change since signing is due to revised terms of the transaction as well as other changes in customary and transaction-specific price adjustments.

During the three months ended March 31, 2026, the Company incurred a pre-tax loss of $182 million, resulting primarily from the Amendment, which we determined to be indicative of conditions that existed as of March 31, 2026. The loss was determined by comparing the carrying value of the discontinued operation to the fair value of the discontinued operation, defined as the sale price less estimated selling costs. The loss is presented within Net loss from discontinued operations attributable to Owens Corning, net of tax, on the Consolidated Statements of Earnings. An estimated valuation allowance of $590 million is recorded within Non-current assets of discontinued operations, on the Consolidated Balance Sheets. The Company closed the sale on April 30, 2026 and does not expect to recognize material incremental charges related to the transaction.

The following table summarizes (Loss)/Earnings from discontinued operations attributable to Owens Corning, net of tax included within the Consolidated Statements of Earnings:

**3.** **SEGMENT INFORMATION**

Effective January 1, 2025, due to a strategic shift in how we manage our business as a result of the GR Agreement, we reorganized our reportable segments to align to our new operating and management structure. The Company now has three reportable segments: Roofing, Insulation and Doors. The Company's vertically integrated glass nonwoven business that supports the Company's Roofing business and other building products customers, along with its composite lumber business, were integrated into the Roofing segment. Two glass melting plants, which make fiber for the nonwoven business, were integrated into the Insulation segment.

Operating segments are aggregated into reportable segments based on consideration of the following factors: similarity of economic characteristics, the nature of business activities, the management structure directly accountable to our chief operating decision maker ("CODM") for operating and administrative activities, availability of discrete financial information and information presented to the Board of Directors and investors. Accounting policies for the segments are the same as those for the Company. The Company's three reportable segments are defined as follows:

*Roofing* – Within our Roofing segment, the Company manufactures and sells residential roofing shingles, oxidized asphalt materials, roofing components and composite lumber primarily used in residential construction. Roofing also manufactures and sells glass mat and specialty veil materials used in building and construction applications.

*Insulation –* Within our Insulation segment, the Company manufactures and sells thermal and acoustical batts, loose fill insulation, spray foam insulation, wet use chopped strand, foam sheathing and accessories. It also manufactures and sells glass fiber pipe insulation, energy efficient flexible duct media, bonded and granulated stone wool insulation, cellular glass insulation, and foam insulation used in above- and below-grade construction applications.

**<u>EARNINGS BEFORE INTEREST, TAXES, DEPRECIATION AND AMORTIZATION</u>**

The Company identifies the Chief Executive Officer as the chief operating decision maker ("CODM"). In applying the criteria set forth in the standards for reporting information about segments in financial statements, we have determined that we have three reportable segments – Roofing, Insulation, and Doors. The key factors used to identify these reportable segments are the organization and alignment of our internal operations and the nature of our products. The CODM uses earnings before interest, taxes, depreciation and amortization ("EBITDA") for each reportable segment to assess segment performance and make decisions on the allocation of resources. Segment EBITDA targets are established on an annual basis and used by the CODM throughout the year to compare with actual results. Quarterly forecasts supplement annual targets and provide incremental information utilized to assess the performance of a segment. Segment EBITDA variance analysis further provides insight into segment operational cost optimization.

The Company does not regularly provide significant segment expense detail to the CODM. EBITDA by segment consists of net sales less related costs and expenses, which are mainly comprised of cost of sales and marketing and administrative costs. EBITDA is presented on a basis that is used internally for evaluating segment performance. Certain items, such as general corporate expenses or income and certain other expense or income items, are excluded from the internal evaluation of segment performance. Accordingly, these items are not reflected in EBITDA for our reportable segments and are included within Corporate, Other and Eliminations.

Machinery and equipment includes certain precious metals used in our production tooling, which comprise approximately 3% and 4% of total machinery and equipment as of March 31, 2026 and December 31, 2025, respectively.

Our production tooling needs are changing due to the announced sale of our GR business. As a result, the Company sold certain precious metals resulting in gains of $2 million and $9 million for the three months ended March 31, 2026 and March 31, 2025, respectively. These gains are included in Other expense, net on the Consolidated Statements of Earnings and are reflected in the Corporate, Other and Eliminations reporting category. The cash proceeds from the sales are included in Net cash flow used for investing activities in the Consolidated Statements of Cash Flow.

We also exchanged certain precious metals used in production tooling for certain other precious metals to be used in production tooling. During the three months ended March 31, 2026, these non-cash exchanges resulted in a net increase to Machinery and equipment of $10 million and a gain of $10 million. There were no significant non-cash exchanges during the three months ended March 31, 2025. These gains are included in Other expense, net on the Consolidated Statements of Earnings and reflected in the Corporate, Other and Eliminations reporting category. These non-cash investing activities are not included in Net cash flow used by investing activities in the Consolidated Statements of Cash Flows. We do not expect these non-cash exchanges to materially impact our current or future capital expenditure requirements or rate of depletion.

**7.** **DIVESTITURES**

On February 24, 2026, the Company entered into an agreement and sold its distribution business, that was part of the Doors segment, which further aligns with our strategy to streamline operations in the segment. The business represented annual net revenues of approximately $70 million. As a result of the sale, the Company received consideration of approximately $40 million, net of cash sold and subject to customary working capital adjustments, and recognized a pre-tax gain on sale of approximately $4 million during the three months ended March 31, 2026, which is recorded in Other expense, net on the Consolidated Statements of Earnings.

On November 4, 2024, the Company entered into a related party agreement to sell its building materials business in China and Korea to a member of the business' management team. The disposal further aligns with the strategy to reshape the Company to focus on residential and commercial building products in North America and Europe. The transaction included six insulation manufacturing facilities in China and a roofing manufacturing facility in Korea. The building materials business, within the Insulation segment, represented annual revenues of approximately $130 million. The Company completed the transaction in July 2025 and is in the process of finalizing certain related transfers, which are expected to be completed by the end of the second quarter of fiscal year 2026.

**<u>Senior Notes</u>**

The Company issued $500 million of 2027 senior notes with an annual interest rate of 5.500%, $800 million of 2034 senior notes with an annual interest rate of 5.700% and $700 million of 2054 senior notes with an annual interest rate of 5.950% on May 31, 2024. The proceeds from these notes were used to repay a portion of the outstanding borrowings under the 364-Day Credit Facility (as defined below) that was used to fund a portion of the purchase of Masonite in the second quarter of 2024 and to pay related fees and expenses.

On May 1, 2024, in connection with the acquisition of Masonite, we commenced an offer to exchange (the "Exchange Offer") any and all of Masonite's outstanding 3.50% Senior Notes due 2030 (the "Masonite 2030 notes") for new 3.50% Senior Notes due 2030 of Owens Corning (the "Owens Corning 2030 notes"). On May 22, 2024, 99.51% of the outstanding Masonite 2030 notes were exchanged and we issued $373 million aggregate principal amount of Owens Corning 2030 notes, which was a non-cash financing transaction for the Company. Interest on the notes is payable semiannually in arrears on February 15 and August 15 each year, beginning on August 15, 2024. Following the settlement of the Exchange Offer, approximately $2 million of the Masonite 2030 notes that were not exchanged remain outstanding, which has been recorded on the Consolidated Balance Sheets.

On April 15, 2024, in connection with the acquisition of Masonite, we commenced a tender offer (the "Tender Offer") to purchase any and all of Masonite's outstanding 5.375% Senior Notes due 2028 (the "Masonite 2028 notes") with an aggregate value of $501 million. On May 13, 2024, 94.25% of the outstanding Masonite 2028 notes were validly tendered, with Owens Corning making a cash payment on May 16, 2024 of approximately $480 million, inclusive of $7 million of interest and $1 million premium on tender. Following the settlement of the Tender Offer, approximately $29 million of the Masonite 2028 notes that were not tendered remained outstanding. On February 1, 2025, the Company issued a par call to repay the remaining portion of its outstanding Masonite 2028 notes for $30 million inclusive of accrued interest.

The Company issued $400 million of 2026 senior notes on August 8, 2016. Interest on the notes is payable semiannually in arrears on February 15 and August 15 each year, beginning on February 15, 2017.

As of March 31, 2026, the $400 million outstanding balance related to the 2026 senior notes was recorded in Long-term debt – current portion on the Consolidated Balance Sheets.

The Company issued $550 million of 2036 senior notes on October 31, 2006. Interest on the notes is payable semiannually in arrears on June 1 and December 1 each year, beginning on June 1, 2007. The proceeds of these notes were used to pay certain unsecured and administrative claims, finance general working capital needs and for general corporate purposes.

Collectively, the Company's senior notes above, other than the Masonite 2028 notes or the Masonite 2030 notes, are referred to as the "Senior Notes." The Senior Notes are general unsecured obligations of the Company and rank *pari passu* with all existing and future senior unsecured indebtedness of the Company. The Company has the option to redeem all or part of the Senior Notes at any time at a "make-whole" redemption price. The Company is subject to certain covenants in connection with the issuance of the Senior Notes that it believes are usual and customary. The Company was in compliance with these covenants as of March 31, 2026.

**<u>Senior Revolving Credit Facility</u>**

On March 5, 2025, the Company amended its senior revolving credit facility (the "Senior Revolving Credit Facility") to increase the available principal amount from $1.0 billion to $1.5 billion and to extend the maturity to March 2030. The Senior Revolving Credit Facility includes both borrowings and letters of credit. Borrowings under the Senior Revolving Credit Facility may be used for general corporate purposes and working capital. The Company has the discretion to borrow under multiple options, which provide for varying terms and interest rates including the United States prime rate, federal funds rate plus a spread or forward-looking term rate based on the Secured Overnight Financing Rate ("Term SOFR") plus a spread.

The Senior Revolving Credit Facility contains various covenants, including a maximum allowed leverage ratio, that the Company believes are usual and customary for a senior unsecured credit agreement. The Senior Revolving Credit Facility was amended in February 2026 to exclude specified 2025 non-cash impairment charges from the leverage ratio calculation. The Company was in compliance with the covenants in the Senior Revolving Credit Facility as of March 31, 2026.

**<u>Commercial Paper</u>**

On March 5, 2025, the Company established a $1.5 billion commercial paper program ("CP Program") for the issuance of unsecured commercial paper notes (the "CP Notes") with maturities ranging up to 397 days from the date of issuance. The CP Notes may not be voluntarily prepaid or redeemed by the Company prior to maturity and rank *pari passu* with all existing and future senior unsecured indebtedness of the Company. The proceeds from the CP Notes will be used to finance the Company's short-term liquidity needs and other general corporate purposes. The Senior Revolving Credit Facility is designated to be a liquidity backstop for the CP Notes outstanding under the CP Program. We do not intend to have outstanding borrowings under the CP Program in excess of available capacity under our Senior Revolving Credit Facility. As of March 31, 2026, there were $380 million of CP Notes outstanding under the CP Program with a weighted average interest rate and weighted average maturity period of 4.10% and 9 days, respectively. As of December 31, 2025, there were $50 million of CP Notes outstanding

under the CP Program with a weighted average interest rate and weighted average maturity period of 3.95% and 13 days, respectively. The CP Notes are reported net of any discount and are included within Short-term debt on the Company's Consolidated Balance Sheets.

**11.** **CONTINGENT LIABILITIES AND OTHER MATTERS**

The Company may be involved in various legal and regulatory proceedings relating to employment, antitrust, tax, product liability, environmental, contracts, intellectual property and other matters (collectively, "Proceedings"). The Company regularly reviews the status of such Proceedings along with legal counsel. Liabilities for such Proceedings are recorded when it is probable that the liability has been incurred and when the amount of the liability can be reasonably estimated. Liabilities are adjusted when additional information becomes available. Except as set forth below under "Litigation and Regulatory Proceedings," management believes that the amount of any reasonably possible losses in excess of any amounts accrued, if any, with respect to such Proceedings or any other known claim, including the matters described below under the caption Environmental Matters (the "Environmental Matters"), are not material to the Company's financial statements. While the likelihood is remote, the disposition of the Proceedings and Environmental Matters could have a material impact on the results of operations, cash flows or liquidity in any given reporting period.

**<u>Litigation and Regulatory Proceedings</u>**

The Company is involved in litigation and regulatory proceedings from time to time in the regular course of its business. The Company believes that adequate provisions for resolution of all contingencies, claims and pending matters have been made for probable losses that are reasonably estimable.

During the second quarter of 2023, the Company's subsidiary, Paroc Group OY ("Paroc"), which the Company acquired in 2018, notified the appropriate European maritime regulatory authorities that specific products in its marine insulation product line may not meet certain fire safety requirements in accordance with their certifications. Paroc voluntarily withdrew these specific products from the market, issued recalls and suspended distribution and sales of these products (the "Recalled Products"). As of March 31, 2026 we have included a liability within Other current liabilities on the Consolidated Balance Sheets in the amount of $83 million to cover the costs of the remediation associated with the Recalled Products. We do not expect to incur further material charges related to the Recalled Products.

Due to the discovery of these nonconformances, the Company reviewed the Paroc insulation product portfolio. That review has concluded. The review included the Company's assessment of potential nonconformances related to certain ventilation duct and steel beam insulation products. Paroc suspended sales of these affected insulation products but has not issued any recalls. While we expect to incur costs associated with the resolution of the identified ventilation duct and steel beam insulation products, the amount or range of any potential loss cannot be reasonably estimated at this time.

**<u>Environmental Matters</u>**

The Company has established policies and procedures designed to ensure that its operations are conducted in compliance with all relevant laws and regulations and that enable the Company to meet its high standards for corporate sustainability and environmental stewardship. Our manufacturing facilities are subject to numerous foreign, federal, state and local laws and regulations relating to the presence of hazardous materials, pollution and protection of the environment, including emissions to air, reductions of greenhouse gases, discharges to water, management of hazardous materials, handling and disposal of solid wastes, use of chemicals in our manufacturing processes and remediation of contaminated sites. All Company manufacturing facilities are either ISO 14001 certified or deploy environmental management systems based on ISO 14001 principles. The Company's 2030 Sustainability Goals include significant global reductions in energy use, water consumption, waste to landfill, and emissions of greenhouse gases, fine particulate matter, and volatile organic air emissions and protection of biodiversity.

Owens Corning is involved in remedial response activities and is responsible for environmental remediation at a number of sites, including certain of its currently owned or formerly owned plants. These responsibilities arise under a number of laws, including, but not limited to, the Federal Resource Conservation and Recovery Act, and similar state or local laws pertaining to the management and remediation of hazardous materials and petroleum. The Company has also been named a potentially responsible party under the U.S. Federal Superfund law, similar state or local laws pertaining to the management and remediation of hazardous materials and petroleum. The Company became involved in these sites as a result of government action or in connection with business acquisitions. As of March 31, 2026, the Company was involved with a total of 27 sites worldwide, including 12 Superfund and state or country equivalent sites and 15 owned or formerly owned sites. None of the liabilities for these sites are individually significant to the Company.

Remediation activities generally involve a potential range of activities and costs related to soil, groundwater and sediment contamination. This can include pre-cleanup activities such as fact-finding and investigation, risk assessment, feasibility studies, remedial action design and implementation (where actions may range from monitoring to removal of contaminants, to installation of longer-term remediation systems). A number of factors affect the cost of environmental remediation, including the number of parties involved in a particular site, the determination of the extent of contamination, the length of time the remediation may require, the complexity of environmental regulations, variability in clean-up standards, the need for legal action and changes in remediation technology. Taking these factors into account, Owens Corning reasonably estimates the costs of remediation to be paid over a period of years. The Company accrues an amount on an undiscounted basis, when a liability is probable and reasonably estimable. Actual cost may differ from these estimates for the reasons mentioned above. Changes in required remediation procedures or timing of those procedures, or discovery of contamination at additional sites, could result in material increases to the Company's environmental obligations.

**<u>Other Matters</u>**

As a result of the decision of the U.S. Supreme Court in February 2026, the Company may be entitled to a refund of tariffs previously paid on certain imported products under the International Emergency Economic Powers Act. The Company estimates that approximately $50 million of tariff payments may be eligible for refund as a result of the decision. As of March 31, 2026, the Company has not recorded an asset related to this matter. The Company continues to evaluate the matter and will recognize a refund when the right to receive such amounts becomes realized or realizable in accordance with ASC 450, Contingencies.

**12.** **STOCK COMPENSATION**

**Description of the Plan**

On April 20, 2023, the Company's stockholders approved the Owens Corning 2023 Stock Plan (the "2023 Stock Plan") which authorizes grants of stock options, stock appreciation rights, stock awards (including restricted stock awards, restricted stock units and bonus stock awards), performance share awards and performance share units. At March 31, 2026, the number of shares remaining available under the 2023 Stock Plan for all stock awards was 2.2 million. Future equity-based awards to Company employees who were former Masonite employees may be granted from the remaining available shares under the Masonite Stock Plan. At March 31, 2026, the number of shares remaining available under the Masonite Stock Plan was 0.6 million shares of Owens Corning common stock.

Prior to the 2023 Stock Plan, employees were eligible to receive stock awards under the Owens Corning 2019 Stock Plan.

**Total Stock-Based Compensation Expense**

Stock-based compensation expense included in Marketing and administrative expenses in the accompanying Consolidated Statements of Earnings is as follows:

---

| | | |
|:---|:---|:---|
| | **Three Months Ended March 31,** | **Three Months Ended March 31,** |
| *(In millions)* | **2026** | **2025** |
| Total stock-based compensation expense from continuing operations | $17 | $20 |
| Total stock-based compensation expense from discontinued operations | 1 | 1 |
| Total stock-based compensation expense | $18 | $21 |

---

<u>Restricted Stock Units</u>

The Company has granted restricted stock units ("RSUs") under its stockholder-approved stock plans. Generally, all outstanding RSUs will fully settle in stock. Compensation expense for RSUs is measured based on the closing market price of the stock at date of grant and is recognized on a straight-line basis over the vesting period, which is typically three years. The Stock Plan allows alternate vesting schedules for death, disability and retirement.

The following table shows a summary of the Company's RSU activity:

---

| | | |
|:---|:---|:---|
| | **Number of<br>RSUs** | **Weighted-Average<br>Fair Value** |
| Balance at December 31, 2025 | 994201 | $122.10 |
| Granted | 322440 | 131.86 |
| Vested | (307257) | 135.03 |
| Forfeited | (16636) | 142.27 |
| Balance at March 31, 2026 | 992748 | $120.92 |

---

As of March 31, 2026, there was $71 million of total unrecognized compensation cost related to RSUs. That cost is expected to be recognized over a weighted-average period of 1.96 years. The total grant date fair value of stock vested during the three months ended March 31, 2026 and 2025 was $41 million and $40 million, respectively.

<u>Performance Share Units</u>

The Company has granted performance share units ("PSUs") as a part of its long-term incentive plan. All outstanding PSUs will fully settle in stock. The amount of shares ultimately distributed from PSUs will vary depending on each award's design and are contingent on meeting the applicable internal performance metrics and external stock performance metrics. PSUs typically vest after a three-year period.

Performance of these metrics is monitored quarterly and if it becomes probable that the internal-based performance goals will not be achieved or will be exceeded, compensation expense recognized will be adjusted and previous surplus compensation expense recognized will be reversed or additional expense will be recognized. The expected term represents the period from the grant date to the end of the three-year performance period. Pro-rata vesting may be utilized in the case of death, disability or retirement, and awards, if earned, will be paid at the end of the three-year period.

*PSUs granted from 2023-2025*

The initial fair value for all internal performance metric PSUs is based on the grant date stock price. Internal performance metric PSU grants issued from 2023 through 2025 contained both a service and performance condition. In the three months ended March 31, 2025, the grant date fair value of the granted PSUs was $171.94.

The external-based metric PSUs vest after a three-year period. Outstanding grants issued from 2023 to 2025 are based on the Company's total stockholder return relative to a peer group. The amount of stock distributed will vary depending on the relative stockholder return performance. The fair value of external-based metric PSUs has been estimated at the grant date using a Monte Carlo simulation that uses various assumptions.

The following table provides a summary of the assumptions for PSUs granted in 2025:

---

| | |
|:---|:---|
| | **Three Months Ended March 31,** |
| | **2025** |
| Expected volatility | 32.78% |
| Risk free interest rate | 4.14% |
| Expected term (in years) | 2.90 |
| Grant date fair value of units granted | $221.54 |

---

The risk-free interest rate was based on zero-coupon United States Treasury STRIPS at the grant date. The expected term represents the period from the grant date to the end of the three-year performance period.

*PSUs granted in 2026*

Beginning in 2026, all PSUs issued are internal performance metric PSUs that are subject to a modifier adjustment based on the Company's total shareholder return relative to a peer group. The number of shares earned depends on the achievement of both performance and market conditions. The fair value of PSUs granted for the three months ended March 31, 2026 has been estimated at the grant date using a Monte Carlo simulation with various assumptions.

<u>Employee Stock Purchase Plan</u>

The Owens Corning Employee Stock Purchase Plan ("ESPP") is a tax-qualified plan under Section 423 of the Internal Revenue Code. The purchase price of shares purchased under the ESPP is equal to 85% of the lower of the fair market value of shares of Owens Corning common stock at the beginning or ending of the offering period, which is a six month period ending on May 31 and November 30 of each year. On April 16, 2020, the Company's stockholders approved the Amended and Restated Owens Corning Employee Stock Purchase Plan which increased the number of shares available for issuance under the plan by 4.2 million shares. As of March 31, 2026, 2.8 million shares remain available for purchase.

Included in total stock-based compensation is $3 million of expense related to the Company's ESPP for each of the three months ended March 31, 2026 and 2025, respectively. As of March 31, 2026, the Company had $2 million of total unrecognized compensation costs related to the ESPP.

Basic earnings per share is calculated by dividing earnings attributable to Owens Corning by the weighted-average number of shares of the Company's common stock outstanding during the period. Outstanding shares consist of issued shares less treasury stock.

On May 13, 2025, the Board of Directors approved a new share repurchase program under which the Company is authorized to repurchase up to 12 million shares of the Company's outstanding common stock (the "2025 Repurchase Authorization"). On December 1, 2022, the Board of Directors approved a share repurchase program under which the Company is authorized to repurchase up to 10 million shares of the Company's outstanding common stock (together with the 2025 Repurchase Authorization, the "Repurchase Authorizations"). The Repurchase Authorizations enable the Company to repurchase shares through the open market, privately negotiated, or other transactions. The actual number of shares repurchased will depend on timing, market conditions and other factors and will be at the Company's discretion.

The Company repurchased no shares of its common stock during the three months ended March 31, 2026 under the Repurchase Authorizations. As of March 31, 2026, 12.5 million shares remained available for repurchase under the Repurchase Authorizations. The Company repurchased 0.7 million shares of its common stock for $101 million, inclusive of applicable taxes, during the three months ended March 31, 2025.

For each of the three months ended March 31, 2026 and March 31, 2025, the Company did not have any non-vested restricted stock units or non-vested performance share units that had an anti-dilutive effect on earnings per share.

---

*This Management's Discussion and Analysis (*"*MD&A*"*) is intended to help investors understand Owens Corning, our operations and our present business environment. MD&A is provided as a supplement to, and should be read in conjunction with, our Consolidated Financial Statements and the accompanying Notes thereto contained in this report. Unless the context requires otherwise, the terms "Owens Corning," "Company," "we" and "our" in this report refer to Owens Corning and its subsidiaries.*

**GENERAL**

Owens Corning is a branded building products leader with three complementary businesses providing roofing, insulation and doors primarily for residential markets in North America and Europe. As described below, the Company has three reportable segments: Roofing, Insulation and Doors. Through these lines of business, the Company manufactures and sells products that provide durable, sustainable and energy-efficient solutions. We are a market leader in many of our major product categories.

**EXECUTIVE OVERVIEW**

Net earnings from continuing operations attributable to Owens Corning were earnings of $38 million in the first quarter of 2026, compared to earnings of $255 million in the first quarter of 2025. The Company generated $369 million in adjusted earnings before interest, taxes, depreciation and amortization ("Adjusted EBITDA") from continuing operations in the first quarter of 2026, compared to $565 million in the first quarter of 2025. See the Adjusted Earnings Before Interest, Taxes, Depreciation and Amortization From Continuing Operations section of the MD&A for further information regarding Adjusted EBITDA from continuing operations, including the reconciliation to Net earnings from continuing operations attributable to Owens Corning. First quarter of 2026 segment earnings before interest, taxes, depreciation and amortization ("EBITDA") performance compared to the first quarter of 2025 decreased $101 million in our Roofing segment, decreased $58 million in our Insulation segment and decreased $34 million in our Doors segment. Within our Corporate, Other and Eliminations category, General corporate expenses and other increased by $3 million.

*Glass Reinforcements Divestiture*

On February 13, 2025, the Company entered into a definitive agreement ("GR Agreement") for the sale of our global glass reinforcements ("GR") business for a purchase price of approximately $436 million, less costs to sell. The GR business, historically part of the Company's Composites segment, manufactures, fabricates, and sells glass fiber reinforcements for a wide variety of applications in wind energy, infrastructure, industrial, transportation and consumer markets.

The transaction represented a strategic shift that has a major effect on the Company's operations and financial results and therefore, beginning with the quarterly report on Form 10-Q for the period ended March 31, 2025, the GR business financial results are reflected in the Company's consolidated financial statements as discontinued operations for all periods presented.

As a result of classifying the GR business as a discontinued operation, a portion of the Goodwill from our former Composites reporting unit was allocated to the balance sheets of the discontinued operation. As of the date of classification of the GR business as a discontinued operation, the Company determined the amount of Goodwill to allocate based on the relative fair values of the discontinued operation and the former Composites reporting unit. This resulted in an allocation of Goodwill to the discontinued operation of $98 million as of the held for sale date.

On April 14, 2026, the Company entered into an amendment to the GR Agreement ("Amendment") to address changing market conditions. The Amendment includes a $110 million decrease in the purchase price, the transfer of approximately $32 million in carrying value of additional assets at close and elimination of the $225 million promissory notes that were to be issued to the Company by the purchasers. As of March 31, 2026, the estimated purchase price was $413 million, net of cash, less costs to sell. The change since signing is due to revised terms of the transaction as well as other changes in customary and transaction-specific price adjustments. The sale subsequently closed on April 30, 2026. The sale completes Owens Corning's review of strategic alternatives for the business, announced on February 9, 2024, and aligns with the strategy to reshape the Company to focus on residential and commercial building products in North America and Europe.

During the three months ended March 31, 2026, the Company incurred a pre-tax loss of $182 million, resulting from the Amendment, which we determined to be indicative of conditions that existed as of March 31, 2026. The loss was determined by comparing the carrying value of the discontinued operation to the fair value of the discontinued operation, defined as the sale price less estimated selling costs. The loss is presented within Net loss from discontinued operations attributable to Owens Corning, net of tax, on the Consolidated Statements of Earnings. An estimated valuation allowance of $590 million is recorded within Non-current assets of discontinued operations, on the Consolidated Balance Sheets.

*Tariff and Trade Uncertainties*

Beginning in the first quarter of 2025, the U.S. government announced additional tariffs on goods imported into the U.S. from numerous countries and multiple nations have responded with reciprocal tariffs and other actions. The Company continues to monitor the economic effects of such announcements. The Company has implemented short- and long-term mitigation efforts.

Based on the current tariff policies, the Company expects to partially offset the operating profit impact of the enacted tariffs with supply chain adjustments and productivity and cost savings actions. If additional tariffs or other trade restrictions are enacted, or if the Company is unable to offset their impact, then demand for our products and the Company's revenue and profitability could be adversely impacted.

Following the decision of the U.S. Supreme Court, the Company may be entitled to a refund of tariffs previously paid on certain imported products under the International Emergency Economic Powers Act. The Company estimates that approximately $50 million of tariff payments may be eligible for refund as a result of the decision; however, no asset has been recorded as of March 31, 2026.

The Consolidated Results discussion below provides a summary of our results and the trends affecting our business, and should be read in conjunction with the more detailed Segment Results discussion that follows.

NET SALES

Net sales decreased $265 million in the first quarter 2026 compared to the first quarter 2025. The decrease was primarily driven by lower volumes across all segments. The remaining variance was primarily attributable to lower selling prices, partially offset by favorable mix in all segments.

GROSS MARGIN

Gross margin decreased $215 million in the first quarter 2026 compared to the first quarter 2025. The decrease was primarily driven by lower sales volumes across all three segments, lower selling prices, the impact of production downtime, and input cost inflation.

MARKETING AND ADMINISTRATIVE EXPENSES

Marketing and administrative expenses decreased $3 million in the first quarter 2026 compared to the first quarter 2025.

OTHER EXPENSE, NET

Other expense, net increased $73 million in the first quarter 2026 compared to the first quarter 2025. The increase was primarily driven by higher restructuring costs and an increase in the liability for the Paroc marine recall.

| **ITEM 2.** | **MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (continued)** |

---

INTEREST EXPENSE, NET

Interest expense, net increased $2 million in the first quarter 2026 compared to the first quarter 2025. The increase was driven by lower interest income due to lower cash balances.

INCOME TAX EXPENSE

Income tax expense for the three months ended 2026 was $15 million. The Company's effective tax rate for the first quarter 2026 was 28% on pre-tax income of $54 million. The difference between the 28% effective tax rate and the U.S. federal statutory tax rate of 21% is primarily due to U.S. state and local income tax expense, foreign tax effects, and changes in unrecognized tax benefits.

The realization of deferred tax assets depends on achieving a certain minimum level of future taxable income. Management currently believes that it is not reasonably possible that the minimum level of taxable income will be met within the next 12 months to reduce the valuation allowances of certain foreign jurisdictions.

Income tax expense for the three months ended 2025 was $88 million. The Company's effective tax rate for the first quarter 2025 was 26%. The difference between the 26% effective tax rate and the U.S. federal statutory tax rate of 21% is primarily due to U.S. state and local income tax expense and foreign rate differential.

**<u>Restructuring Costs</u>**

The Company has incurred restructuring and other exit costs in connection with its global cost reduction, product line and productivity initiatives. These costs are recorded within Corporate, Other and Eliminations. Please refer to Note 9 of the Consolidated Financial Statements for further information on the nature of these costs.

The following table presents the impact and respective location of these income (expense) items on the Consolidated Statements of Earnings From Continuing Operations:

**<u>Adjusted Earnings Before Interest, Taxes, Depreciation and Amortization From Continuing Operations</u>**

Adjusted EBITDA from continuing operations is a non-GAAP measure that excludes certain items that management does not allocate to our segment results because it believes they are not representative of the Company's ongoing operations. Adjusted EBITDA from continuing operations is used internally by the Company for various purposes, including reporting results of operations to the Board of Directors of the Company, analysis of performance and related employee compensation measures. Although management believes that these adjustments result in a measure that provides a useful representation of our operational performance, the adjusted measure should not be considered in isolation or as a substitute for Net earnings from continuing operations attributable to Owens Corning as prepared in accordance with accounting principles generally accepted in the United States.

**<u>Segment Results</u>**

EBITDA by segment consists of net sales, less related costs and expenses plus depreciation and amortization. EBITDA is presented on a basis that is used internally for evaluating segment performance. Certain items, such as general corporate expenses or income and certain other expense or income items, are excluded from the internal evaluation of segment performance. Accordingly, these items are not reflected in EBITDA for our reportable segments and are included in the Corporate, Other and Eliminations category, which is presented following the discussion of our reportable segments. Segment EBITDA is the principal measure used by the chief operating decision maker ("CODM") to assess segment performance and make decisions on the allocation of resources.

***Roofing***

NET SALES

In our Roofing segment, net sales decreased $160 million in the first quarter 2026 compared to the first quarter 2025. Lower volumes of approximately 14% and lower selling prices of $13 million were slightly offset by favorable mix.

EBITDA

In our Roofing segment, EBITDA decreased $101 million in the first quarter 2026 compared to the first quarter 2025. The decrease was primarily driven by lower volumes, higher manufacturing costs of $17 million, lower selling prices of $13 million, input cost inflation of $6 million, and the impact of production downtime.

OUTLOOK

In our Roofing segment, the Company expects non-discretionary roof replacement activity to remain solid in the near-term. Uncertainties that may impact Roofing demand include demand from storms and other weather-related events (including the frequency thereof), competitive pricing pressure and the cost and availability of raw materials, particularly asphalt. The Company expects global non-residential construction markets to be relatively stable in the near-term. The Company will continue to focus on managing costs, capital expenditures and working capital to best service the market demand.

***Insulation***

The table below provides a summary of net sales and EBITDA for the Insulation segment:

---

| | | |
|:---|:---|:---|
| | **Three Months Ended March 31,** | **Three Months Ended March 31,** |
| *(In millions)* | **2026** | **2025** |

| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*% change from prior year* | *-5 %* | *-5 %* |
| **EBITDA** | $167 | $225 |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*EBITDA as a % of net sales* | *19 %* | *25 %* |

---

NET SALES

In our Insulation segment, net sales decreased $42 million in the first quarter 2026 compared to the first quarter 2025. Lower volumes of 3% and lower selling prices of $21 million were partially offset by slightly favorable mix. A favorable impact of $25 million from translating sales denominated in foreign currencies into United States dollars offset the unfavorable impact from the divestiture of our building materials business in China and Korea.

EBITDA

In our Insulation segment, EBITDA decreased $58 million in the first quarter 2026 compared to the first quarter 2025. The decrease was driven by lower selling prices of $21 million, the impact of production downtime of $20 million and input cost inflation of $11 million. The remaining variance primarily resulted from lower volumes, partially offset favorable mix.

OUTLOOK

The outlook for Insulation demand is driven by North American new residential construction, remodeling and repair activity, as well as non-residential construction activity in the United States, Canada, Europe and Latin America. Demand in non-residential insulation markets is most closely correlated to industrial production growth and overall economic activity in the markets we serve. Demand for residential insulation is most closely correlated to U.S. housing starts.

During the first quarter of 2026, the average Seasonally Adjusted Annual Rate ("SAAR") of U.S. housing starts was 1.419 million starts, which was up from 1.370 million starts in the first quarter of 2025.

The Company expects the new residential construction market in North America to remain challenged in the near-term, driven by an overall weakness in housing starts due to affordability challenges and consumer uncertainty. The global non-residential construction markets are expected to be relatively stable in the near-term. The Company continues to concentrate on driving productivity, managing costs, capital expenditures and working capital as we position ourselves to expand capacity within our existing manufacturing network.

| **EBITDA** | $34 | $68 |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*EBITDA as a % of net sales* | *7 %* | *13 %* |

---

NET SALES

In our Doors segment, net sales decreased $65 million in the first quarter 2026 compared to the first quarter 2025, primarily due to lower volumes of 12%. A $10 million unfavorable impact from the divestiture of our distribution business was offset by a $6 million favorable impact of translating sales denominated in foreign currencies into United States dollars and favorable mix.

EBITDA

In our Doors segment, EBITDA decreased $34 million in the first quarter 2026 compared to the first quarter 2025. Lower volumes, input cost inflation of $10 million, higher manufacturing costs of $9 million and the impact of production downtime were partially offset by $9 million of lower selling, general and administrative costs and slightly favorable mix.

OUTLOOK

The outlook for the Doors segment is driven by the new residential construction and residential repair and remodeling markets in North America and Europe. The Company expects the North America residential new construction market to remain challenged in the near-term, with discretionary residential repair and remodeling activity in North America remaining soft. The Company will concentrate on managing costs, capturing synergies, capital expenditures and working capital.

***Corporate, Other and Eliminations***

Certain items, such as general corporate expenses or income and certain other expense or income items, are excluded from the internal evaluation of segment performance. Accordingly, these items are not reflected in EBITDA for our reportable segments and are included within Corporate, Other and Eliminations.

The table below provides a summary of EBITDA for the Corporate, Other and Eliminations category:

| **EBITDA** | $(138) | $(59) |

---

EBITDA

The impact on EBITDA from Corporate, Other and Eliminations in the first quarter 2026 was $79 million higher compared to the first quarter 2025. The increase was primarily driven by higher restructuring costs and an increase in the liability for the Paroc marine recall.

General corporate expense and other in the first quarter 2026 was $3 million higher than in the first quarter 2025.

OUTLOOK

In 2026, we expect general corporate expenses to be approximately $245 million to $255 million.

**LIQUIDITY, CAPITAL RESOURCES AND OTHER RELATED MATTERS**

**<u>Liquidity</u>**

The Company's primary sources of liquidity are its balance of Cash and cash equivalents from continuing operations of $272 million as of March 31, 2026, its commercial paper program ("CP Program") and Senior Revolving Credit Facility (as defined below).

The Company has a $1.5 billion senior revolving credit facility (the "Senior Revolving Credit Facility") that has been amended from time to time. The Senior Revolving Credit Facility was amended in March 2025 to increase the borrowing limit from $1.0 billion to $1.5 billion and extend the maturity date to March 2030. No other significant terms impacting liquidity were amended.

The agreement governing our Senior Revolving Credit Facility contains various covenants that we believe are usual and customary. These covenants include a maximum allowed leverage ratio. The Senior Revolving Credit Facility was amended in February 2026 to exclude specified 2025 non-cash impairment charges from the leverage ratio calculation. We were in compliance with the covenants in the Senior Revolving Credit Facility as of March 31, 2026.

On March 5, 2025, the Company established the CP Program for the issuance of $1.5 billion in unsecured commercial paper notes (the "CP Notes") with maturities up to 397 days from the date of issuance. We do not intend to have outstanding commercial paper borrowings in excess of available capacity under the Senior Revolving Credit Facility.

As a holding company, we have no operations of our own and most of our assets are held by our direct and indirect subsidiaries. Dividends and other payments or distributions from our subsidiaries will be used to meet our debt service and other obligations and to enable us to pay dividends to our stockholders. Please refer to the Risk Factors disclosed in Item 1A of the Company's Annual Report on Form 10-K for the year ended December 31, 2025 (the "2025 Form 10-K") for details on the factors that could inhibit our subsidiaries' abilities to pay dividends or make other distributions to the parent company.

**<u>Cash Flows</u>**

Cash and cash equivalents were $285 million as of March 31, 2026, compared to $440 million as of March 31, 2025. Cash and cash equivalents held by foreign subsidiaries may be subject to foreign withholding taxes upon repatriation to the U.S. As of March 31, 2026 and December 31, 2025, the Company had $142 million and $97 million, respectively, in cash and cash equivalents in certain of its foreign subsidiaries. The Company continues to assert indefinite reinvestment for certain of its continuing operations in accordance with Accounting Standards Codification ("ASC") 740 based on the laws as of enactment of the tax legislation.

*Operating activities:* Net cash flow used for operating activities increased by $105 million for the three months ended March 31, 2026 compared to the same period in 2025. The increase was primarily due to lower cash earnings, partially offset by the change in working capital. For the three months ended March 31, 2026, there was no depreciation and amortization related to discontinued operations.

*Investing activities:* Net cash flow used for investing activities increased by $31 million for the three months ended March 31, 2026 compared to the same period in 2025. The increase was primarily driven by higher cash paid for property, plant and equipment and lower proceeds from sale of assets or affiliates. For the three months ended March 31, 2026, cash paid for property, plant and equipment related to discontinued operations was $23 million.

*Financing activities:* Net cash flow provided by financing activities decreased by $29 million for the three months ended March 31, 2026 compared to the same period in 2025. The decrease was primarily driven by lower net proceeds from CP Notes, partially offset by lower treasury stock repurchases and lower payments on long-term debt in the current year.

**<u>Material Cash Requirements</u>**

Our anticipated uses of cash include capital expenditures, working capital needs, share repurchases, meeting financial obligations, payments of any dividends authorized by our Board of Directors, acquisitions, restructuring actions and pension contributions. We expect that our cash on hand, coupled with future cash flows from operations and other available sources of liquidity, including our Senior Revolving Credit Facility and our CP Program, will provide ample liquidity to enable us to meet our cash requirements for at least the next 12 months and foreseeable future thereafter.

Please refer to Item 7, Management's Discussion and Analysis of Financial Condition and Results of Operations, included in the 2025 Form 10-K for more details on these material cash requirements. During the first quarter of 2026, there have been no material changes to our expected uses of cash and contractual obligations.

**<u>Debt</u>**

As of March 31, 2026, the Company had $5.5 billion of total debt. The Company's current portion of long-term debt primarily relates to $400 million of the current portion of 3.4% senior notes maturing in the third quarter of 2026. Further discussion of the amount and timing of the future scheduled maturities of our senior notes can be found in Note 10 of the Consolidated Financial Statements. As of March 31, 2026, the Company's Short-term debt includes $380 million of CP Notes.

On March 5, 2025, the Company amended the Senior Revolving Credit Facility to increase the available principal amount from $1.0 billion to $1.5 billion and to extend the maturity to March 2030. The Company had no borrowings outstanding and $1.5 billion available under the Senior Revolving Credit Facility as of March 31, 2026.

On March 5, 2025, the Company established a CP Program for the issuance of CP Notes with maturities ranging up to 397 days from the date of issuance. As of March 31, 2026, there were $380 million of CP Notes outstanding under the CP Program with a weighted average interest rate and weighted average maturity period of 4.10% and 9 days, respectively. We do not intend to have outstanding borrowings under the CP Program in excess of available capacity under our Senior Revolving Credit Facility.

**<u>Supplier Finance Programs</u>**

We review supplier terms and conditions on an ongoing basis, and have negotiated payment terms extensions in recent years in connection with our efforts to reduce working capital and improve cash flow. Separate from those terms extension actions, certain of our subsidiaries have entered into paying agency agreements with third-party administrators. These voluntary supply chain finance programs (collectively, the "Programs") generally give participating suppliers the ability to sell, or otherwise pledge as collateral, their receivables from the Company to the participating financial institutions, at the sole discretion of both the suppliers and financial institutions. The Company is not a party to the arrangements between the suppliers and the financial institutions. The Company's obligations to its suppliers, including amounts due and scheduled payment dates, are not impacted by the suppliers' decisions to sell, or otherwise pledge as collateral, amounts under these arrangements. The Company's payment terms to the financial institutions, including the timing and amount of payments, are based on the original supplier invoices. One of the Programs includes a parent guarantee to the participating financial institution for a certain U.S. subsidiary that, at the time of the respective program's inception in 2015, was a guarantor subsidiary of the Company's credit agreement. The obligations are presented as Accounts payable within Total current liabilities on the Consolidated Balance Sheets and all activity related to the obligations is presented within operating activities on the Consolidated Statements of Cash Flow.

The desire of suppliers and financial institutions to participate in the Programs could be negatively impacted by, among other factors, the availability of capital committed by the participating financial institutions, the cost and availability of our suppliers' capital, a credit rating downgrade or deteriorating financial performance of the Company or its participating subsidiaries, or other changes in financial markets beyond our control. We do not expect these risks, or potential long-term growth of our Programs, to materially affect our overall financial condition, as we expect a significant portion of our payments to continue to be made outside of the Programs. Accordingly, we do not believe the Programs have materially impacted our current period liquidity, and do not believe that the Programs are reasonably likely to materially affect liquidity in the future.

Please refer to the *Supplier Finance Programs* section in Note 1 of the Consolidated Financial Statements for a roll-forward of outstanding obligations under the supplier finance programs.

**<u>Fair Value Measurement</u>**

**SAFETY**

Working safely is an expectation at Owens Corning. We believe this organization-wide expectation provides for a safer work environment for employees, improves our manufacturing processes, reduces our costs and enhances our reputation. Furthermore, striving to be a world-class leader in safety provides a platform for all employees to understand and apply the resolve necessary to be a high-performing, global organization. One of our primary safety measures is the Recordable Incidence Rate ("RIR") as defined by the United States Bureau of Labor Statistics. For the three months ended March 31, 2026, our RIR was 0.46, compared to 0.54 in the same period a year ago.

## Exhibit 10.2

**<u>Exhibit 10.2</u>**

**PERFORMANCE SHARE UNIT AWARD AGREEMENT**

pursuant to the

**OWENS CORNING**

**2023 STOCK PLAN**

**PERFORMANCE SHARE UNIT AWARD**

OWENS CORNING, a Delaware corporation (the "Company"), has granted to **[Participant Name]** (the "Holder"), as of **[Grant Date]** (the "Grant Date"), pursuant to the provisions of the Owens Corning 2023 Stock Plan (the "Plan"), **[Number of Shares Granted]** share-settled Performance Share Units (the "Units") relating to shares of common stock, $0.01 par value, of the Company ("Stock"), upon and subject to the restrictions, terms and conditions set forth below and in the Plan (the "Award"). The Units comprising the Award may be recorded in an unfunded Unit account in the Holder's name maintained by the Company. References to employment by the Company shall also mean employment by a Subsidiary. Capitalized terms not defined herein shall have the meanings specified in the Plan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1.<u>Performance Criteria; Performance Targets; Performance Period</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)For purposes of the Award, performance criteria consist of one or more specific "Performance Measures," as defined in Section 1.2 of the Plan, which have been selected by the Compensation Committee of the Board of Directors of the Company (the "Committee") in accordance with the Plan (the "Performance Criteria"). Based on such Performance Criteria, the Committee shall determine if, and to the extent, the Award shall become vested and payable to the Holder as a result of the achievement of performance targets which have been established by the Committee at the "Entry," "Target" and "Maximum" levels. These Performance Criteria and performance targets have been communicated to the Holder in a written document separate from the Award ("Statement of Performance Goals"). The Award shall be payable as follows: (i) if the Entry level is not achieved, no amount shall be payable pursuant to this Award, (ii) if the Target level is achieved, the Target amount shall be payable pursuant to the Award, (iii) if the Maximum level is achieved, two times the Target amount shall be payable pursuant to the Award, and (iv) the amount payable pursuant to the Award shall be interpolated on a linear basis for achievement between the Entry level and the Target level and between the Target level and the Maximum level; provided, however, that notwithstanding the prior portion of this Section 1, in all cases, the Committee retains full negative discretion to reduce the payment for the Award, including to zero.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)The achievement of the performance targets specified in Section 1(a) hereof and as set forth on the Statement of Performance Goals shall be for the performance period commencing as of January 1, 2026 and ending on December 31, 2028 (the "Performance Period") and such achievement shall be determined by the Committee as of December 31, 2028 (the "Determination Date").

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.<u>Vesting</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)<u>Continuous Service</u>. Subject to the terms and conditions of this Agreement, the Units shall become fully vested on the Determination Date, provided that the

------

Holder remains in continuous service with the Company or any Subsidiary or affiliate of the Company as an employee, director or consultant ("Continuous Service") through and including the Determination Date and to the extent that the performance targets described in the Statement of Performance Goals for the Units are achieved. As used herein, the term "vest" shall mean no longer subject to a substantial risk of forfeiture.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)<u>Termination of Continuous Service</u>.

&nbsp;&nbsp;&nbsp;&nbsp;(i) &nbsp;&nbsp;&nbsp;&nbsp; <u>Retirement</u>. Notwithstanding Section 2(a), if, after the Holder has been in Continuous Service for twelve months during the Performance Period and prior to the Determination Date and prior to a Change in Control the Holder's Continuous Service is terminated by reason of Retirement, then the Holder shall be entitled to a pro-rata portion of the Award determined by the product of (A) the number of Units the Holder would have received based on the Company's performance under the Performance Criteria as of the Determination Date, multiplied by (B) a fraction, the numerator of which is the number of full months of Continuous Service rendered since the beginning of the Performance Period as of the date of termination, and the denominator of which is 36. Settlement of the Units under this section, if any, shall be made as soon as practicable after the Determination Date, but in any event between January 1 and March 15, 2029.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) &nbsp;&nbsp;&nbsp;&nbsp;<u>Death or Disability</u>. Notwithstanding Section 2(a) or Section 2(b)(i), if, after the Grant Date and prior to the Determination Date and prior to a Change in Control the Holder's Continuous Service is terminated by reason of Death or Disability, then the payment of the Award shall be determined in accordance with the achievement of the Performance Criteria as of the Determination Date, and the Holder shall at the time of such termination be vested in full. Settlement of the Units under this section, if any, shall be made as soon as practicable after the Determination Date, but in in any event between January 1 and March 15, 2029.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii)&nbsp;&nbsp;&nbsp;&nbsp;<u>Forfeiture</u>. The Holder shall forfeit the entire Award if, after the Grant Date and prior to the Determination Date and prior to a Change in Control, the Holder's Continuous Service is terminated for any reason other than death or Disability or Retirement that occurs on or after the first anniversary of the Grant Date.

&nbsp;&nbsp;&nbsp;&nbsp;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.<u>Payment</u>. The Units that vest in accordance with the terms of Section 2 shall be paid to the Holder in Stock or deferred stock units pursuant to Section 6.14(m); <u>provided</u>, <u>however</u>, that no fractional share of Stock shall be issued pursuant to the Award. All Stock payable pursuant to this Section 3 shall be paid to the Holder after the Determination Date but in any event between January 1 and March 15, 2029. Notwithstanding any provisions of this Agreement to the contrary, no payment shall occur pursuant to this Section 3 unless and until the Committee has certified that the applicable performance criteria have been satisfied, which certification shall occur within 60 days of the date on which the Performance Period ends.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4.<u>Change in Control</u>. In the event of a Change in Control that occurs after the Grant Date and prior to the Determination Date, the Performance Criteria shall be deemed to be satisfied at the maximum level as set forth on the Statement of Performance Goals and the Units shall become fully vested as of such Change in Control. The Units vested in accordance with the

------

terms of this Section 4 shall be paid to the Holder within 10 days following such Change in Control in Stock as provided in Section 3 hereof, subject to Section 6.13(l).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.<u>Withholding Taxes</u>. To the extent that the Company or a Subsidiary is required to withhold federal, state, local, employment, or foreign taxes or other amounts, or, to the extent permitted under Section 409A of the Code, any other applicable taxes (the "Required Tax Payments"), in connection with the Holder's right to receive shares of Stock under this Agreement (regardless of whether the Holder is entitled to the delivery of any Stock at that time), and the amounts available to the Company for such withholding are insufficient, as a condition precedent to the delivery to the Holder of any such Stock upon the vesting of the Units, the Holder agrees that the Required Tax Payments shall be satisfied by the Company withholding from the Stock otherwise to be delivered to the Holder pursuant to the Award having a Fair Market Value, determined as of the date of taxation, equal to the Required Tax Payments. No shares of Stock shall be delivered to the Holder until the Required Tax Payments have been satisfied in full.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6.<u>Additional Terms and Conditions of Award</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6.1.<u>Award Subject to Acceptance of Agreement</u>. The Award shall be null and void unless the Holder shall accept this Agreement by executing it in an enforceable manner, including through an electronic acceptance, in such form as is determined to be acceptable within the discretion of the Committee.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6.2.&nbsp;&nbsp;&nbsp;&nbsp;<u>Agreement Not To Compete and Not To Solicit.</u>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)In exchange for the consideration provided by the Company in this Agreement, the Holder agrees that, during the Covenant Period, the Holder shall not, without the prior written consent of the Company: (i) become directly or indirectly engaged or involved, as an owner, principal, employee, officer, director, manager, independent contractor, consultant, representative, seller, distributor, agent, advisor, lender or in any other capacity, with or for any Competitor of the Company or any Subsidiary; (ii) participate in the research or development, manufacture, and/or any business, fabrication, marketing, sale or distribution of any products or services that are competitive with or similar to any products or services then being developed, manufactured, fabricated, marketed, sold or distributed by the Company or any Subsidiary; (iii) directly or indirectly, on behalf of the Holder or any other person or entity, offer, market, sell or distribute, or participate in offering, marketing, selling or distributing any products or services that are competitive with or similar to any products or services then offered , marketed, sold or distributed by the Company or any Subsidiary to any customer of the Company or any Subsidiary, or to the Holder's knowledge, potential customer of the Company or any Subsidiary; (iv) directly or indirectly, on behalf of the Holder or any other person or entity, solicit, induce, recruit, hire, or encourage any employee, independent contractor, consultant, or sales representative of the Company or any Subsidiary to leave their employment; or (v) directly or indirectly, engage, or attempt to engage, on behalf of any Competitor of the Company or any Subsidiary, any customer, vendor, supplier, distributor, independent contractor, agent, or other business relationship of the Company or any Subsidiary, or engage in any other action that would reasonably be expected to terminate or negatively impact any such business relationship of the Company or any Subsidiary; provided, however, that the Holder's direct or indirect ownership of less than 1% of the outstanding capital stock of a company whose capital stock is listed on a national securities exchange or regularly traded in an over-the-counter market, shall not be deemed to be a violation of this Agreement. Notwithstanding any provision of the Plan or of this Agreement to the contrary, any violation of this section by the Holder shall result in the immediate forfeiture and cancellation of the portion of the Award which is not vested as of such date.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)The Holder agrees that money damages would not be a sufficient remedy for any breach of this Section 6.2 by the Holder and that, in addition to all other remedies which may be available to the Company, the Company shall be entitled to specific performance and injunctive or other equitable relief as a remedy for any such breach. The Holder further agrees to waive any requirement for the securing or posting of any bond in connection with any such remedy.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)The Holder agrees and acknowledges that (i) the services rendered by the Holder to the Company are special and of great value to the Company, (ii) the market for the Company's products and services is worldwide and the Company regularly transacts business on a worldwide basis, (iii) the covenants contained in this Section 6.2 are reasonable and necessary for the protection of the Company's legitimate business interests, (iv) the grant of the Award to the Holder is good and sufficient consideration for such covenants, and (v) the Holder's compliance with such covenants will not preclude or unreasonably restrict the Holder from engaging in other activities for the purpose of earning a livelihood.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)As used herein, (i) the term "Competitor" means any person, or entity that (A) is engaged in, or that has plans to become engaged in the research, development, manufacture, fabrication, marketing, sale or distribution of products or services that are the same as, or serve a substantially similar purpose or function as any products or services that were researched, developed, manufactured, fabricated, marketed, sold, or distributed by any business unit of the Company or any Subsidiary for which the Holder performed any work or services at any time during the last twenty-four (24) months during which the Holder was employed by Company or any Subsidiary; and (B) directly or indirectly conducts any business operations anywhere within North America or anywhere else in the world where the Holder has engaged in business activities on behalf of the Company or any Subsidiary: and (ii) the term "Covenant Period" means the period ending on the first anniversary of the date the Holder's termination of employment with the Company or any Subsidiary, regardless of the circumstances relating to such termination of employment (e.g., resignation, retirement, disability, termination by the Company for cause, or termination by the Company without cause).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6.2.<u>Nontransferability of Units</u>. Prior to the Determination Date, the Units subject to the Award and not then vested may not be transferred by the Holder other than by will, the laws of descent and distribution or pursuant to beneficiary designation procedures approved by the Company. Except to the extent permitted by the foregoing, upon any attempt to sell, transfer, assign, pledge, hypothecate or encumber, or otherwise dispose of such Units, the Award shall immediately become null and void.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6.3.<u>Rights as a Stockholder and No Dividend Equivalents</u>. Until Units become vested and Stock is issued, if any, under this Agreement, the Holder shall not be a stockholder of record with respect to the Stock underlying any unvested Units and shall have no voting or distribution rights with respect to such Stock. Furthermore, with respect to each of the Units covered by this Agreement, the Holder shall not be credited with any dividend equivalents.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6.4.<u>Adjustment</u>. Subject to Section 6.7 of the Plan, in the event of any stock split, stock dividend, recapitalization, reorganization, merger, consolidation, combination, exchange of shares, liquidation, spin-off or other similar change in capitalization or event, or any distribution to holders of Stock other than a regular cash dividend, or any other corporate transaction or event having an effect similar to any of the foregoing, the number and class of securities subject to the Units and the other terms of the Units shall be appropriately adjusted by the Committee. If any adjustment would result in a fractional security being subject to the Units, the Company shall pay the Holder in connection with the vesting, if any, of such fractional security an amount in cash determined by multiplying such fraction (rounded to the nearest hundredth) by the fair market value on the Determination Date. The decision of the Committee regarding any such adjustment shall be final, binding and conclusive.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6.5.<u>Compliance with Applicable Law</u>. The Award is subject to the condition that if the listing, registration or qualification of the Stock subject to the Units upon any securities exchange or under any law, or the consent or approval of any governmental body, or the taking of any other action is necessary or desirable as a condition of, or in connection with, the vesting or delivery of Stock hereunder, the Units subject to the Award shall not vest or be delivered, in whole or in part, unless such listing, registration, qualification, consent or approval shall have been effected or obtained, free of any conditions not acceptable to the Company. The Company agrees to use reasonable efforts to effect or obtain any such listing, registration, qualification, consent or approval. Further, the Holder agrees that to the extent the issuance of Stock in the Holder's jurisdiction is impossible, illegal, unauthorized, or, in the Company's discretion, is imprudent or is otherwise impracticable for any reason, the Company may, in its discretion, either deem the Award to be a cash award of equivalent cash value or may direct the sale of all Stock subject to the Award and settle the Award in cash locally with the Holder.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6.6.<u>Delivery.</u> The Company, subject to the withholding provisions of Section 5, shall promptly deliver or cause to be delivered one or more shares of Stock represented by the vested Units which are payable under Section 3. The Company shall pay all original issue or transfer taxes and all fees and expenses incident to such delivery, except as otherwise provided in Section 5.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6.7.<u>Award Confers No Rights to Continued Employment</u>. The granting of this Award does not entitle the Holder to any award other than that specifically granted under the Plan, or to any future awards under the Plan or any similar plan. The Award does not become part of the contract of employment or any other employment relationship with the Holder's employer, and the Award is not a guarantee of continued employment. Moreover, the Award or any future awards do not become a term or condition of employment. The Holder understands and accepts that the awards granted under the Plan are entirely at the discretion of the Company and that the Company retains the right to amend or terminate the Plan and/or the Holder's participation therein, at any time, at the Company's sole discretion and without notice.

The Holder hereby waives any and all rights to compensation or damages as a result of the termination of employment with the Company for any reason whatsoever insofar as those rights result or may result from: (a) the loss or diminution in value of any rights under the Plan; or (b) the Holder ceasing to have any rights under, or ceasing to be entitled to any rights under the Plan as a result of such termination.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6.9.<u>Incorporation of the Plan</u>. The Plan, as it exists on the date of this Agreement and as amended from time to time, is hereby incorporated by reference and made a part hereof, and the Award and this Agreement shall be subject to all terms and conditions of the Plan and any subsequent amendments to the Plan. In the event of any conflict between the provisions of this Agreement and the provisions of the Plan, the terms of the Plan shall control. The Holder hereby acknowledges receipt of a copy of the Plan.

The Plan and this Agreement constitute the entire agreement and understanding between the parties with respect to the matters described herein and supersede all prior and contemporaneous agreements and understandings, oral and written, between the parties with respect to such subject matter; provided, however, that the covenants contained in Section 6.2 shall complement and shall be in addition to, and shall not supersede similar covenants made by the Holder to the Company or any Subsidiary, including covenants made in the Agreement-Protection of Owens Corning Proprietary Interests or the Intellectual Property Agreement if the Holder has executed such an agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)<u>Modification</u>. No modification or waiver of any of the provisions of this Agreement shall be effective unless in writing and signed by the party against whom it is sought to be enforced, and specifically references this Performance Share Unit Award Agreement by name.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e)<u>Waiver</u>. The failure of any party hereto at any time to require performance by another party of any provision of this Agreement shall not affect the right of such party to require performance of that provision, and any waiver by any party of any breach of any provision of this Agreement shall not be construed as a waiver of any continuing or succeeding breach of such provision, a waiver of the provision itself, or a waiver of any right under this Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f)<u>Fees and Expenses; Legal Compliance</u>. The Company shall pay all fees and expenses necessarily incurred by the Company in connection with this Agreement and will from time to time use its reasonable efforts to comply with all laws and regulations which, in the opinion of counsel to the Company, are applicable thereto.

This Agreement shall be governed and construed and the legal relationships of the parties determined in accordance with the laws of the State of Delaware without reference to principles of conflict of laws.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(h)<u>Data Privacy</u>. By signing this Agreement, including by way of electronic acceptance of this Agreement by means acceptable to the Company, the Holder explicitly and unambiguously consents to the collection, processing, and transfer (electronically or otherwise) of the Holder's personal data as described in this Agreement by and among, as applicable, the Company, Subsidiaries, the Holder's employer (the "Employer"), and any third parties as necessary, for the exclusive purpose of implementing, administering and managing the Holder's participation in the Plan. Moreover, the Holder explicitly acknowledges and agrees that the Company and the Employer may hold certain personal information about the Holder (including, but not limited to, the Holder's name, home address, telephone number, email address, date of birth, employment status, tax identification number, passport or other identification number, salary, nationality, job title, any Stock awarded, cancelled, purchased, exercised, vested, unvested or outstanding in the Holder's favor, and data for tax withholding purposes) for the purposes of implementing, administering and managing the Plan ("Data"). The Holder understands that Data will be transferred to third parties assisting the Company with the implementation, administration and management of the Plan. The Holder expressly authorizes such transfer to and processing by third parties. Furthermore, the Holder understands that the recipients of the Data may be located in the United States or elsewhere, and that the recipients' country (e.g., the United States) may have different data privacy laws and protections than the Holder's country. The Holder explicitly consents to the transfer of the Holder's personal data to countries other than the Holder's country of employment. The Company will take reasonable measures to keep the Holder's personal data private, confidential, and accurate. The Holder understands that Data will be held only as long as is necessary to implement, administer and manage the Holder's participation in the Plan. The Holder further understands that the Holder may request a list with the names and addresses of any potential recipients of the Data by contacting the Holder's local human resources contact, may obtain details with respect to the

------

collection, storage, processing and transfer of Data in relation to the Plan participation, may also request access to and updates of such Data, if needed, by contacting the Holder's local Human Resources contact, and may refuse or withdraw the consents herein, in any case without cost, by contacting in writing the Holder's local human resources contact. The Holder understands, however, that refusing or withdrawing the Holder's consent may affect the Holder's ability to participate in the Plan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i)<u>Clawback Policy</u>. The Holder hereby acknowledges and agrees that this Award and this Agreement (and any settlement of this Award) are subject to the terms and conditions of the Company's clawback policies as may be in effect from time to time (the "Compensation Recovery Policy"), and that relevant sections of this Agreement shall be deemed superseded by and subject to the terms and conditions of the Compensation Recovery Policy from and after the effective date thereof. Further, by receiving this Award, the Holder (i) consents to be bound by the terms of the Compensation Recovery Policy, as applicable, (ii) agrees and acknowledges that the Holder is obligated to and will cooperate with, and will provide any and all assistance necessary to, the Company in any effort to recover or recoup any compensation or other amounts subject to clawback or recovery pursuant to the Compensation Recovery Policy and/or applicable laws, rules, regulations, stock exchange listing standards or other Company policy, and (iii) agrees that the Company may enforce its rights under the Compensation Recovery Policy through any and all reasonable means permitted under applicable law as it deems necessary or desirable under the Compensation Recovery Policy. Such cooperation and assistance shall include (but is not limited to) executing, completing and submitting any documentation necessary, or consenting to Company action, to facilitate the recovery or recoupment by the Company from the Holder of any such compensation or other amounts, including from the Holder's accounts or from any other compensation, to the extent permissible under Section 409A of the Code.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(j)<u>Whistleblowers</u>. For the avoidance of doubt, notwithstanding anything to the contrary in the Plan, this Agreement or in any other agreement, contract or arrangement with the Company or any Subsidiary or affiliate, or in any policy, procedure or practice of the Company or any Subsidiary or affiliate (collectively, the "Arrangements"), nothing in the Arrangements or otherwise limits the Holder's right to any monetary award offered by a government-administered whistleblower award program for providing information directly to a government agency (including the Securities and Exchange Commission pursuant to Section 21F of the Exchange Act, the Dodd-Frank Wall Street Reform and Consumer Protection Act or The Sarbanes-Oxley Act of 2002, or any comparable government agency pursuant to any comparable legislation in non-U.S. jurisdictions).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(k)<u>Company to Reserve Stock</u>. The Company shall at all times prior to the expiration or termination of the Units reserve and keep available, either in its treasury or out of its authorized but unissued Stock, the full number of shares of Stock subject to the Units from time to time.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(l)<u>Compliance with Section 409A of the Code</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i)&nbsp;&nbsp;&nbsp;&nbsp;To the extent applicable, it is intended that this Agreement and the Plan comply with, or are exempt from, the provisions of Section 409A of the Code, so that the income inclusion provisions of Section 409A(a)(1) of the Code do not apply to the Holder. This Agreement and the Plan shall be administered in a manner consistent with this intent, and any provision that would cause this Agreement or the Plan to fail to satisfy Section 409A of the Code shall have no force and effect until amended to comply with Section 409A of the Code (which amendment may be retroactive to the extent permitted by Section 409A of the Code and may be made by the Company without the consent of the Holder).

------

&nbsp;&nbsp;&nbsp;&nbsp;(ii)&nbsp;&nbsp;&nbsp;&nbsp;To the extent the Holder has a right to receive payment pursuant to this Agreement, the payment is deferred compensation subject to Section 409A, and the event triggering the right to payment does not constitute a permitted distribution event under Section 409A(a)(2) of the Code, then notwithstanding anything to the contrary in this Agreement, issuance of Stock in payment of the vested Units will be made to the Holder, to the extent necessary to comply with Section 409A of the Code, on the earliest of: (A) the Determination Date; (B) the Holder's "separation from service" with the Company (determined in accordance with Section 409A of the Code), provided, that if the Holder is a "specified employee" (within the meaning of Section 409A of the Code), the Holder's date of payment of the Award pursuant to this clause (ii) shall be the date that is the first business day following six months after the date of the Holder's separation of service with the Company; (C) the Holder's death; (D) the Holder's permanent disability (within the meaning of Section 409A(a)(2)(C) of the Code); or (E) a change in control event (within the meaning of Section 409A of the Code).

&nbsp;&nbsp;&nbsp;&nbsp;(iii)&nbsp;&nbsp;&nbsp;&nbsp;Reference to Section 409A of the Code will also include any regulations, or any other guidance, promulgated with respect to such Section by the U.S. Department of the Treasury or the Internal Revenue Service.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(m)<u>Deferred Stock Units</u>. Performance share units granted under the Plan, including Units granted pursuant to this Award, may be settled in the form of deferred stock units pursuant to a valid deferral election by the Holder. The Holder shall have all rights incident to ownership of such deferred stock units, including, but not limited to, the right to receive dividend equivalents in the form of additional deferred stock units.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(n)<u>Severability</u>. If any covenant or other term in this Agreement (including, without limitation, any covenant in Section 6.2 hereof) is determined by a court of competent jurisdiction to be wholly or partially unenforceable, the Holder agrees that: (i) this Agreement or any portion hereof may be reformed so that such covenant or other term is enforceable to the maximum extent permitted by law; (ii) such determination shall not be a bar to or in any way diminish the Company's right to enforce any such covenant or other term in any other jurisdiction; and (iii) the unaffected provisions of this Agreement shall be unimpaired and shall remain in full force and effect. Without limiting the generality of the foregoing, if any covenant in this Agreement shall be determined by a court of competent jurisdiction to be unenforceable by reason of its extending for too great a period of time or over too great a geographical area or by reason of its being too extensive in any other respect, it will be interpreted to extend only over the maximum period of time for which it may be enforceable, over the maximum geographical area as to which it may be enforceable, or to the maximum extend in all other respect as to which it may be enforceable, all as determined by such court.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6.15.<u>Provisions Relating to Participants in Specific U.S. States</u>. Notwithstanding any provisions in this Agreement, the Award shall also be subject to the special terms and conditions set forth in the U.S. State-Specific Addendum attached as <u>Appendix A</u> to this Agreement if the Holder is employed and/or resides in specific states or if the Company determines that the application of such terms and conditions is necessary or advisable in order to comply with applicable law. The U.S. State-Specific Addendum attached hereto as <u>Appendix A</u> constitutes part of this Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;OWENS CORNING, a Delaware corporation (the "Company"), has granted to **[Participant Name]** (the "Holder"), as of **[Grant Date]** (the "Grant Date"), pursuant to the provisions of the Owens Corning 2023 Stock Plan (the "Plan"), **[Number of Shares Granted]** restricted stock units (the "Units") relating to shares of common stock, $0.01 par value, of the Company ("Stock"), upon and subject to the restrictions, terms and conditions set forth below and in the Plan (the "Award"). Each Unit shall provide for the issuance and transfer to the Holder of one share of Stock upon the lapse of the restrictions set forth in Section 1 hereof. Upon issuance and transfer of the Stock subject to the Units following the lapse of the Restriction Period, the Holder shall have all rights incident to ownership of such Stock, including, but not limited to, voting rights and the right to receive dividends. References to employment by the Company shall also mean employment by a Subsidiary. Capitalized terms not defined herein shall have the meanings specified in the Plan.

1.<u>Restriction Period and Vesting</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)<u>General</u>. Subject to Sections 1(b), 1(c), 1(d), and 1(e), the Units shall vest and the restrictions shall lapse with respect to 33.3% of the Units on each anniversary of the Grant Date (each such anniversary, a "Vesting Date") until the Units are fully vested (such three-year period, the "Restriction Period"). As used herein, the term "vest" shall mean no longer subject to a substantial risk of forfeiture.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)<u>Death or Disability</u>. Notwithstanding Section 1(a), if, prior to the end of the Restriction Period, the Holder's employment with the Company terminates by reason of death or Disability, the Units that are then unvested shall vest in full, and the restrictions shall lapse, as of the date of such termination.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)<u>Retirement</u>. Notwithstanding Sections 1(a) and 1(b), if, after the Holder has been in continuous Service for twelve months and prior to the end of the Restriction Period the Holder's employment with the Company terminates by reason of Retirement, the portion of the Award that is then unvested shall continue to vest after the date of such termination as if the Holder's employment with the Company continued until the end of the Restriction Period.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)<u>Change in Control</u>. Notwithstanding Sections 1(a), 1(b), and 1(c), in the event of a Change in Control, as defined in the Plan, the Units shall immediately vest in full and the restrictions shall lapse as provided in Section 6.8 of the Plan; <u>provided</u>, <u>however</u>, that in the event that (i) the Units constitute the payment of nonqualified deferred compensation within the meaning of Section 409A of the Internal Revenue Code of 1986, as amended (the "Code"), and (ii) the Change in Control does not constitute a "change in control event" within the meaning of Section 409A of the Code, the Units shall not immediately vest upon such Change in Control,

------

but instead shall vest and be payable in accordance with the vesting schedule set forth in clause (i) of Section 1(a) hereof, or earlier pursuant to Section 1(b) hereof.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e)<u>Forfeiture</u>. If, prior to the end of the Restriction Period, the Holder's employment with the Company terminates for any reason other than death, Disability or Retirement, the Units that are then unvested as of the effective date of the termination of the Holder's employment shall be forfeited by the Holder and such portion shall thereafter be cancelled by the Company.

2.<u>Settlement of Award</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)<u>General</u>. Subject to Section 2(b), one share of Stock will be issued as payment for each Unit that vests pursuant to Section 1(a) or Section 1(c) within 30 days following each Vesting Date.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)<u>Other Payment Events</u>. Notwithstanding Section 2(a), to the extent the Units are vested on the dates set forth below, payment with respect to the vested Units will be made as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i)<u>Death or Disability</u>. Within 30 days of the date of the termination of the Holder's employment with the Company by reason of the Holder's death or Disability, one share of Stock will be issued as payment for each Unit, if any, that vests pursuant to Section 1(b).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii)<u>Change in Control</u>. Within 30 days of a Change in Control, one share of Stock will be issued as payment for each Unit, if any, that vests pursuant to Section 1(d).

3.<u>Rights as a Stockholder and Dividend Equivalents</u>.

During the Restriction Period, the Holder shall not be a stockholder of record with respect to the Stock underlying any unvested Units and shall have no voting rights with respect to such Stock. With respect to each of the Units covered by this Agreement, the Holder shall be credited on the records of the Company with dividend equivalents in an amount equal to the amount per share of Stock of any cash dividends declared by the Board on the outstanding Stock (and the applicable record date occurring) during the period beginning on the Grant Date and ending either on the date on which the Holder receives payment for the Units pursuant to Section 2 hereof or at the time when the Units are forfeited in accordance with Section 1(e) of this Agreement. These dividend equivalents will accumulate without interest and, subject to the terms and conditions of this Agreement, will be paid at the same time, to the same extent and in the same manner, in cash, as the Units for which the dividend equivalents were credited. If the Award is subject to a deferral election as described in Section 5.13 below, dividend equivalents will be accrued in the form of additional Units, with the increase in the number of Units equal to the number of shares of Stock or fractional shares of Stock that could be purchased with the dividends based on the value of the Stock at the time such dividends are paid ("Credited Units"). Such Credited Units shall be subject to the restrictions set forth in Section 1 hereof and shall be paid to the Holder in the time and manner as provided in their deferral election.

4.<u>Withholding Taxes</u>.

------

&nbsp;&nbsp;&nbsp;&nbsp;To the extent that the Company or a Subsidiary is required to withhold federal, state, local, employment, or foreign taxes or other amounts, or, to the extent permitted under Section 409A of the Code, any other applicable taxes (the "Required Tax Payments"), in connection with the Holder's right to receive shares of Stock under this Agreement (regardless of whether the Holder is entitled to the delivery of any Stock at that time), and the amounts available to the Company for such withholding are insufficient, as a condition precedent to the delivery to the Holder of any such Stock upon the vesting of the Units, the Holder agrees that the Required Tax Payments shall be satisfied by the Company withholding from the Stock otherwise to be delivered to the Holder pursuant to the Award having a Fair Market Value, determined as of the date of taxation, equal to the Required Tax Payments. No payments in respect of vested Units shall be delivered to the Holder until the Required Tax Payments have been satisfied in full.

5.<u>Additional Terms and Conditions of Award</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.1<u>Award Subject to Acceptance of Agreement</u>. The Award shall be null and void unless the Holder shall accept this Agreement by executing it in an enforceable manner, including through an electronic acceptance, in such form as is determined to be acceptable within the discretion of the Committee.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.2<u>Agreement Not To Compete and Not To Solicit</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)In exchange for the consideration provided by the Company in this Agreement, the Holder agrees that, during the Covenant Period, the Holder shall not, without the prior written consent of the Company: (i) become directly or indirectly engaged or involved, as an owner, principal, employee, officer, director, manager, independent contractor, consultant, representative, seller, distributor, agent, advisor, lender or in any other capacity, with or for any Competitor of the Company or any Subsidiary; (ii) participate in the research or development, manufacture, and/or any business, fabrication, marketing, sale or distribution of any products or services that are competitive with or similar to any products or services then being developed, manufactured, fabricated, marketed, sold or distributed by the Company or any Subsidiary; (iii) directly or indirectly, on behalf of the Holder or any other person or entity, offer, market, sell or distribute, or participate in offering, marketing, selling or distributing any products or services that are competitive with or similar to any products or services then offered, marketed, sold or distributed by the Company or any Subsidiary to any customer of the Company or any Subsidiary, or to the Holder's knowledge, potential customer of the Company or any Subsidiary; (iv) directly or indirectly, on behalf of the Holder or any other person or entity, solicit, induce, recruit, hire, or encourage any employee, independent contractor, consultant, or sales representative of the Company or any Subsidiary to leave their employment; or (v) directly or indirectly, engage, or attempt to engage, on behalf of any Competitor of the Company or any Subsidiary, any customer, vendor, supplier, distributor, independent contractor, agent, or other business relationship of the Company or any Subsidiary, or engage in any other action that would reasonably be expected to terminate or negatively impact any such business relationship of the Company or any Subsidiary; provided, however, that the Holder's direct or indirect ownership of less than 1% of the outstanding capital stock of a company whose capital stock is listed on a national securities exchange or regularly traded in an over-the-counter market, shall not be deemed to be a violation of this Agreement. Notwithstanding any provision of the Plan or of this Agreement to the contrary, any violation of this section by the Holder shall result in the immediate forfeiture and cancellation of the portion of the Award which is not vested as of such date.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)The Holder agrees that money damages would not be a sufficient remedy for any breach of this Section 5.2 by the Holder and that, in addition to all other remedies which may be available to the Company, the Company shall be entitled to specific performance and injunctive or other equitable relief as a remedy for any such breach. The Holder further agrees to waive any requirement for the securing or posting of any bond in connection with any such remedy.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)The Holder agrees and acknowledges that (i) the services rendered by the Holder to the Company are special and of great value to the Company, (ii) the market for the Company's products and services is worldwide and the Company regularly transacts business on a worldwide basis, (iii) the covenants contained in this Section 5.2 are reasonable and necessary for the protection of the Company's legitimate business interests, (iv) the grant of the Award to the Holder is good and sufficient consideration for such covenants, and (v) the Holder's compliance with such covenants will not preclude or unreasonably restrict the Holder from engaging in other activities for the purpose of earning a livelihood.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)As used herein, (i) the term "Competitor" means any person, or entity that (A) is engaged in, or that has plans to become engaged in the research, development, manufacture, fabrication, marketing, sale or distribution of products or services that are the same as, or serve a substantially similar purpose or function as any products or services that were researched, developed, manufactured, fabricated, marketed, sold, or distributed by any business unit of the Company or any Subsidiary for which the Holder performed any work or services at any time during the last twenty-four (24) months during which the Holder was employed by Company or any Subsidiary; and (B) directly or indirectly conducts any business operations anywhere within North America or anywhere else in the world where the Holder has engaged in business activities on behalf of the Company or any Subsidiary; and (ii) the term "Covenant Period" means the period ending on the first anniversary of the date the Holder's termination of employment with the Company or any Subsidiary, regardless of the circumstances relating to such termination of employment (e.g., resignation, retirement, disability, termination by the Company for cause, or termination by the Company without cause).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.3<u>Nontransferability of Units</u>. During the Restriction Period, the Units subject to the Award and not then vested may not be transferred by the Holder other than by will, the laws of descent and distribution or pursuant to beneficiary designation procedures approved by the Company. Except to the extent permitted by the foregoing, upon any attempt to sell, transfer, assign, pledge, hypothecate or encumber, or otherwise dispose of such Units, the Award shall immediately become null and void.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.4<u>Adjustment</u>. Subject to Section 6.7 of the Plan, in the event of any stock split, stock dividend, recapitalization, reorganization, merger, consolidation, combination, exchange of shares, liquidation, spin-off or other similar change in capitalization or event, or any distribution to holders of Stock other than a regular cash dividend, or any other corporate transaction or event having an effect similar to any of the foregoing, the number and class of securities subject to the Units and the other terms of the Units shall be appropriately adjusted by the Committee. If any adjustment would result in a fractional security being subject to the Units, the Company shall pay the Holder in connection with the vesting, if any, of such fractional security an amount in cash determined by multiplying such fraction (rounded to the nearest hundredth) by the fair market value on the applicable Vesting Date (or the date on which the Units vest pursuant to Sections 1(b) or 1(d)). The decision of the Committee regarding any such adjustment shall be final, binding and conclusive.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.5<u>Compliance with Applicable Law</u>. The Award is subject to the condition that if the listing, registration or qualification of the Stock subject to the Units upon any securities exchange or under any law, or the consent or approval of any governmental body, or the taking of any other action is necessary or desirable as a condition of, or in connection with, the vesting or delivery of Stock hereunder, the Units subject to the Award shall not vest or be delivered, in whole or in part, unless such listing, registration, qualification, consent or approval shall have been effected or obtained, free of any conditions not acceptable to the Company. The Company agrees to use reasonable efforts to effect or obtain any such listing, registration, qualification, consent or approval. Further, the Holder agrees that to the extent the issuance of Stock in the Holder's jurisdiction is impossible, illegal, unauthorized, or, in the Company's discretion, is imprudent or is otherwise impracticable for any reason, the Company may, in its discretion, either deem the Award to be a cash award of equivalent cash value or may direct the sale of all Stock subject to the Award and settle the Award in cash locally with the Holder.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.6<u>Book Entry Record/Delivery of Certificates</u>. Subject to the foregoing paragraph, promptly following the vesting of the Units, in whole or in part, the Stock delivered at vesting shall be recorded in book entry form, unless the Company decides to deliver or cause to be delivered, subject to the withholding provisions of Section 4, one or more certificates representing the number of shares of Stock represented by the vested Units. In the event certificates are delivered, the Company shall pay all original issue or transfer taxes and all fees and expenses incident to such delivery, except as otherwise provided in Section 4.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.7<u>Award Confers No Rights to Continued Employment</u>. The granting of the Units does not entitle the Holder to any award other than that specifically granted under the Plan, nor to any future award under the Plan or any similar plan. The Award does not become part of the contract of employment or any other employment relationship with the Holder's employer, and the Award is not a guarantee of continued employment. Moreover, the Award or any future awards do not become a term or condition of employment. The Holder understands and accepts that the Units granted under the Plan are entirely at the discretion of the Company and that the Company retains the right to amend or terminate the Plan and/or the Holder's participation therein, at any time, at the Company's sole discretion and without notice. The benefits and rights provided under the Plan are not, and should not be considered part of the Holder's salary or compensation for purposes of any other calculation, including calculating any severance, resignation, redundancy or other end of service payments, vacation, bonuses, long-term service awards, indemnification, pension or retirement benefits, or any other payments, benefits or rights of any kind, except as required by applicable law. The Holder hereby waives any and all rights to compensation or damages as a result of the termination of employment with the Company for any reason whatsoever insofar as those rights result or may result from: (a) the loss or diminution in value of any rights under the Plan; or (b) the Holder ceasing to have any rights under, or ceasing to be entitled to any rights under, the Plan as a result of such termination.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.8<u>Decisions of Board or Committee</u>. The Board or the Committee shall have the right to resolve all questions which may arise in connection with the Award. Subject to the terms of the Plan, administration of ministerial, non-substantive aspects of the Award has been

------

delegated to the Company. Any interpretation, determination or other action made or taken by the Board or the Committee, or the Company as its delegate, regarding the Plan or this Agreement shall be final, binding and conclusive.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.9<u>Incorporation of the Plan</u>. The Plan, as it exists on the date of this Agreement and as amended from time to time, is hereby incorporated by reference and made a part hereof, and the Award and this Agreement shall be subject to all terms and conditions of the Plan and any subsequent amendments to the Plan. In the event of any conflict between the provisions of this Agreement and the provisions of the Plan, the terms of the Plan shall control. The Holder hereby acknowledges receipt of a copy of the Plan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.10<u>Value of Units and Common Stock</u>. The Company makes no representation as to the value of the Units. The Company is not responsible for any fluctuations in the value of the Stock.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.11<u>Investment Representation</u>. The Holder hereby represents and covenants that (a) any Stock acquired upon the vesting of the Units will be acquired for investment and not with a view to the distribution thereof within the meaning of the Securities Act of 1933, as amended (the "Securities Act"), unless such acquisition has been registered under the Securities Act and any applicable state securities law; (b) any subsequent sale of any such Stock shall be made either pursuant to an effective registration statement under the Securities Act and any applicable state securities laws, or pursuant to an exemption from registration under the Securities Act and such state securities laws; and (c) if requested by the Company, the Holder shall submit a written statement, in form satisfactory to the Company, to the effect that such representation (i) is true and correct as of the date of acquisition of any shares hereunder or (ii) is true and correct as of the date of any sale of any such Stock, as applicable. As a further condition precedent to the delivery to the Holder of any Stock subject to the Units, the Holder shall comply with all regulations and requirements of any regulatory authority having control of or supervision over the issuance of the Stock and, in connection therewith, shall execute any documents which the Board or any committee authorized by the Board shall in its sole discretion deem necessary or advisable.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.12<u>Notices and Electronic Delivery</u>. The Company may, in its sole discretion, deliver any documents (other than certificates), notices or other communications related to the Units and the Holder's participation in the Plan by electronic means. The Holder hereby consents to receive such documents by electronic delivery and, if requested, agrees to participate in the Plan through an on-line or electronic system established and maintained by the Company or another third party designated by the Company.

&nbsp;&nbsp;&nbsp;&nbsp;Any documents, notices or other communications which are not delivered electronically pursuant to this section shall be in writing and shall be deemed to have been duly given when received, if delivered personally, or when mailed, if sent by first class mail, postage paid, addressed as follows:

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)if to the Company or the Committee, to the attention of the Vice President, Total Rewards, Owens Corning World Headquarters, One Owens Corning Parkway, Toledo, Ohio 43659, or to the attention of such other person or at such other address as the Company, by notice to the Holder, may designate in writing from time to time, and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)if to the Holder, at their address as shown on the records of the Company, or at such other address as the Holder, by notice to the Company, may designate in writing from time to time.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.13<u>Deferral of Units</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)<u>Deferral Election</u>. If the Holder made an election, in accordance with the terms and conditions prescribed by the Company and Section 409A of the Code and pursuant to an election form provided to the Holder by the Company, to defer the receipt of the Units that would have otherwise vested pursuant to Section 1(a), such Units shall be payable at the time and form elected by the Holder pursuant to such election.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)<u>Dividend Equivalents</u>. Until the distribution of Units deferred pursuant to this Section 5.13 (the "Deferral Period"), the Units shall continue to be credited with dividend equivalents, as described in Section 3 hereof.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.14<u>Miscellaneous.</u>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)<u>Successors</u>. This Agreement shall be binding upon and inure to the benefit of any successor or successors of the Company and any person or persons who shall, upon the death of the Holder, acquire any right hereunder in accordance with the Plan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)<u>Counterparts</u>. This Agreement may be executed in one or more counterparts, all of which taken together shall constitute one agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)<u>Entire Understanding</u>. The Plan and this Agreement constitute the entire agreement and understanding between the parties with respect to the matters described herein and supersede all prior and contemporaneous agreements and understandings, oral and written, between the parties with respect to such subject matter; provided, however, that the covenants contained in Section 5.2 shall complement and shall be in addition to, and shall not supersede similar covenants made by the Holder to the Company or any Subsidiary, including covenants made in the Agreement-Protection of Owens Corning Proprietary Interests or the Intellectual Property Agreement if the Holder has executed such an agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)<u>Modification</u>. No modification or waiver of any of the provisions of this Agreement shall be effective unless in writing and signed by the party against whom it is sought to be enforced, and specifically references this Restricted Stock Unit Award Agreement by name.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e)<u>Waiver</u>. The failure of any party hereto at any time to require performance by another party of any provision of this Agreement shall not affect the right of such party to require performance of that provision, and any waiver by any party of any breach of any provision of this Agreement shall not be construed as a waiver of any continuing or succeeding breach of such provision, a waiver of the provision itself, or a waiver of any right under this Agreement.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(g)<u>Governing Law</u>. This Agreement shall be governed and construed and the legal relationships of the parties determined in accordance with the laws of the State of Delaware without reference to principles of conflict of laws.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(h)<u>Data Privacy</u>. By signing this Agreement, including by way of electronic acceptance of this Agreement by means acceptable to the Company, the Holder explicitly and unambiguously consents to the collection, processing, and transfer (electronically or otherwise) of the Holder's personal data as described in this Agreement by and among, as applicable, the Company, Subsidiaries, the Holder's employer (the "Employer"), and any third parties as necessary, for the exclusive purpose of implementing, administering and managing the Holder's participation in the Plan. Moreover, the Holder explicitly acknowledges and agrees that the Company and the Employer may hold certain personal information about the Holder (including, but not limited to, the Holder's name, home address, telephone number, email address, date of birth, employment status, tax identification number, passport or other identification number, salary, nationality, job title, any Stock awarded, cancelled, purchased, exercised, vested, unvested or outstanding in the Holder's favor, and data for tax withholding purposes) for the purposes of implementing, administering and managing the Plan ("Data"). The Holder understands that Data will be transferred to third parties assisting the Company with the implementation, administration and management of the Plan. The Holder expressly authorizes such transfer to and processing by third parties. Furthermore, the Holder understands that the recipients of the Data may be located in the United States or elsewhere, and that the recipients' country (e.g., the United States) may have different data privacy laws and protections than the Holder's country. The Holder explicitly consents to the transfer of the Holder's personal data to countries other than the Holder's country of employment. The Company will take reasonable measures to keep the Holder's personal data private, confidential, and accurate. The Holder understands that Data will be held only as long as is necessary to implement, administer and manage the Holder's participation in the Plan. The Holder further understands that the Holder may request a list with the names and addresses of any potential recipients of the Data by contacting the Holder's local human resources contact, may obtain details with respect to the collection, storage, processing and transfer of Data in relation to the Plan participation, may also request access to and updates of such Data, if needed, by contacting the Holder's local Human Resources contact, and may refuse or withdraw the consents herein, in any case without cost, by contacting in writing the Holder's local human resources contact. The Holder understands, however, that refusing or withdrawing the Holder's consent may affect the Holder's ability to participate in the Plan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i)<u>Clawback Policy</u>. The Holder hereby acknowledges and agrees that this Award and this Agreement (and any settlement of this Award) are subject to the terms and conditions of the Company's clawback policies as may be in effect from time to time (the "Compensation Recovery Policy"), and that relevant sections of this Agreement shall be deemed superseded by and subject to the terms and conditions of the Compensation Recovery Policy from and after the effective date thereof. Further, by receiving this Award, the Holder (i) consents to be bound by the terms of the Compensation Recovery Policy, as applicable, (ii) agrees and acknowledges that the Holder is obligated to and will cooperate with, and will provide any and all assistance necessary to, the Company in any effort to recover or recoup any compensation or other amounts subject to clawback or recovery pursuant to the Compensation Recovery Policy and/or applicable laws, rules, regulations, stock exchange listing standards or other Company policy, and (iii) agrees that the Company may enforce its rights under the Compensation Recovery Policy through any and all reasonable means permitted under applicable law as it deems necessary or desirable under the Compensation Recovery Policy. Such cooperation and

assistance shall include (but is not limited to) executing, completing and submitting any documentation necessary, or consenting to Company action, to facilitate the recovery or recoupment by the Company from the Holder of any such compensation or other amounts, including from the Holder's accounts or from any other compensation, to the extent permissible under Section 409A of the Code.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(j)<u>Whistleblowers</u>. For the avoidance of doubt, notwithstanding anything to the contrary in the Plan, this Agreement or in any other agreement, contract or arrangement with the Company or any Subsidiary or affiliate, or in any policy, procedure or practice of the Company or any Subsidiary or affiliate (collectively, the "Arrangements"), nothing in the Arrangements or otherwise limits the Holder's right to any monetary award offered by a government-administered whistleblower award program for providing information directly to a government agency (including the Securities and Exchange Commission pursuant to Section 21F of the Exchange Act, the Dodd-Frank Wall Street Reform and Consumer Protection Act or The Sarbanes-Oxley Act of 2002, or any comparable government agency pursuant to any comparable legislation in non-U.S. jurisdictions).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(k)<u>Company to Reserve Stock</u>. The Company shall at all times prior to the expiration or termination of the Units reserve and keep available, either in its treasury or out of its authorized but unissued Stock, the full number of shares of Stock subject to the Units from time to time.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(l)<u>Compliance with Section 409A of the Code</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i)To the extent applicable, it is intended that this Agreement and the Plan comply with, or are exempt from, the provisions of Section 409A of the Code, so that the income inclusion provisions of Section 409A(a)(1) of the Code do not apply to the Holder. This Agreement and the Plan shall be administered in a manner consistent with this intent, and any provision that would cause this Agreement or the Plan to fail to satisfy Section 409A of the Code shall have no force and effect until amended to comply with Section 409A of the Code (which amendment may be retroactive to the extent permitted by Section 409A of the Code and may be made by the Company without the consent of the Holder).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii)To the extent the Holder has a right to receive payment pursuant to this Agreement, the payment is deferred compensation subject to Section 409A, and the event triggering the right to payment does not constitute a permitted distribution event under Section 409A(a)(2) of the Code, then notwithstanding anything to the contrary in this Agreement, issuance of cash or Stock in payment of the vested Units will be made to the Holder, to the extent necessary to comply with Section 409A of the Code, on the earliest of: (A) a subsequent Vesting Date; (B) the Holder's "separation from service" with the Company (determined in accordance with Section 409A of the Code), provided, that if the Holder is a "specified employee" (within the meaning of Section 409A of the Code), the Holder's date of payment of the Award pursuant to this clause (ii) shall be the date that is the first business day following six months after the date of the Holder's separation of service with the Company; (C) the Holder's death; (D) the Holder's permanent disability (within the meaning of Section 409A(a)(2)(C) of

------

the Code); or (E) a change in control event (within the meaning of Section 409A of the Code).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii)Reference to Section 409A of the Code will also include any regulations, or any other guidance, promulgated with respect to such Section by the U.S. Department of the Treasury or the Internal Revenue Service.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(m)<u>Severability</u>. If any covenant or other term in this Agreement (including, without limitation, any covenant in Section 5.2 hereof) is determined by a court of competent jurisdiction to be wholly or partially unenforceable, the Holder agrees that: (i) this Agreement or any portion hereof may be reformed so that such covenant or other term is enforceable to the maximum extent permitted by law; (ii) such determination shall not be a bar to or in any way diminish the Company's right to enforce any such covenant or other term in any other jurisdiction; and (iii) the unaffected provisions of this Agreement shall be unimpaired and shall remain in full force and effect. Without limiting the generality of the foregoing, if any covenant in this Agreement shall be determined by a court of competent jurisdiction to be unenforceable by reason of its extending for too great a period of time or over too great a geographical area or by reason of its being too extensive in any other respect, it will be interpreted to extend only over the maximum period of time for which it may be enforceable, over the maximum geographical area as to which it may be enforceable, or to the maximum extend in all other respect as to which it may be enforceable, all as determined by such court.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.15<u>Provisions Relating to Participants in Specific U.S. States</u>. Notwithstanding any provisions in this Agreement, the Award shall also be subject to the special terms and conditions set forth in the U.S. State-Specific Addendum attached as Appendix A to this Agreement if the Holder is employed and/or resides in specific states or if the Company determines that the application of such terms and conditions is necessary or advisable in order to comply with applicable law. The U.S. State-Specific Addendum attached hereto as Appendix A constitutes part of this Agreement.

Notwithstanding Section 1(a), if, prior to the end of the Restriction Period, the Holder's employment with the Company terminates by reason of death or Disability, the Units that are then unvested shall vest in full, and the restrictions shall lapse, as of the date of such termination.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)<u>Change in Control</u>. Notwithstanding Sections 1(a) and 1(b), in the event of a Change in Control, as defined in the Plan, the Units shall immediately vest in full and the restrictions shall lapse as provided in Section 6.8 of the Plan; provided, however, that in the event that (i) the Units constitute the payment of nonqualified deferred compensation within the meaning of Section 409A of the Internal Revenue Code of 1986, as amended (the "Code"), and (ii) the Change in Control does not constitute a "change in control event" within the meaning of Section 409A of the Code, the Units shall not immediately vest upon such Change in Control, but instead shall vest and be payable in accordance with the vesting schedule set forth in clause (i) of Section 1(a) hereof, or earlier pursuant to Section 1(b) hereof.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)<u>Forfeiture</u>. If, prior to the end of the Restriction Period, the Holder's employment with the Company terminates for any reason other than death or Disability, the Units that are then unvested as of the effective date of the termination of the Holder's employment shall be forfeited by the Holder and such portion shall thereafter be cancelled by the Company.

2.<u>Settlement of Award</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)<u>General</u>. Subject to Section 2(b), one share of Stock will be issued as payment for each Unit that vests pursuant to Section 1(a) within 30 days following the end of the Restriction Period.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)<u>Other Payment Events</u>. Notwithstanding Section 2(a), to the extent the Units are vested on the dates set forth below, payment with respect to the vested Units will be made as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i)<u>Death or Disability</u>. Within 30 days of the date of the termination of the Holder's employment with the Company by reason of the Holder's death or Disability, one share of Stock will be issued as payment for each Unit, if any, that vests pursuant to Section 1(b).

3.<u>Rights as a Stockholder and Dividend Equivalents</u>.

During the Restriction Period, the Holder shall not be a stockholder of record with respect to the Stock underlying any unvested Units and shall have no voting rights with respect to such Stock. With respect to each of the Units covered by this Agreement, the Holder shall be credited on the records of the Company with dividend equivalents in an amount equal to the amount per share of Stock of any cash dividends declared by the Board on the outstanding Stock (and the applicable record date occurring) during the period beginning on the Grant Date and ending either on the date on which the Holder receives payment for the Units pursuant to Section 2 hereof or at the time when the Units are forfeited in accordance with Section 1(d) of this Agreement. These dividend equivalents will accumulate without interest and, subject to the terms and conditions of this Agreement, will be paid at the same time, to the same extent and in the same manner, in cash, as the Units for which the dividend equivalents were credited. If the Award is subject to a deferral election as described in Section 5.13 below, dividend equivalents will be accrued in the form of additional Units, with the increase in the number of Units equal to the number of shares of Stock or fractional shares of Stock that could be purchased with the dividends based on the value of the Stock at the time such dividends are paid ("Credited Units"). Such Credited Units shall be subject to the restrictions set forth in Section 1 hereof and shall be paid to the Holder in the time and manner as provided in their deferral election.

4.<u>Withholding Taxes</u>.

To the extent that the Company or a Subsidiary is required to withhold federal, state, local, employment, or foreign taxes or other amounts, or, to the extent permitted under Section 409A of the Code, any other applicable taxes (the "Required Tax Payments"), in connection with the Holder's right to receive shares of Stock under this Agreement (regardless of whether the Holder is entitled to the delivery of any Stock at that time), and the amounts available to the Company for such withholding are insufficient, as a condition precedent to the delivery to the

------

Holder of any such Stock upon the vesting of the Units, the Holder agrees that the Required Tax Payments shall be satisfied by the Company withholding from the Stock otherwise to be delivered to the Holder pursuant to the Award having a Fair Market Value, determined as of the date of taxation, equal to the Required Tax Payments.

No payments in respect of vested Units shall be delivered to the Holder until the Required Tax Payments have been satisfied in full.

5.<u>Additional Terms and Conditions of Award</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.1<u>Award Subject to Acceptance of Agreement</u>. The Award shall be null and void unless the Holder shall accept this Agreement by executing it in an enforceable manner, including through an electronic acceptance, in such form as is determined to be acceptable within the discretion of the Committee.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.2<u>Agreement Not To Compete and Not To Solicit.</u>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)In exchange for the consideration provided by the Company in this Agreement, the Holder agrees that, during the Covenant Period, the Holder shall not, without the prior written consent of the Company: (i) become directly or indirectly engaged or involved, as an owner, principal, employee, officer, director, manager, independent contractor, consultant, representative, seller, distributor, agent, advisor, lender or in any other capacity, with or for any Competitor of the Company or any Subsidiary; (ii) participate in the research or development, manufacture, and/or any business, fabrication, marketing, sale or distribution of any products or services that are competitive with or similar to any products or services then being developed, manufactured, fabricated, marketed, sold or distributed by the Company or any Subsidiary; (iii) directly or indirectly, on behalf of the Holder or any other person or entity, offer, market, sell or distribute, or participate in offering, marketing, selling or distributing any products or services that are competitive with or similar to any products or services then offered, marketed, sold or distributed by the Company or any Subsidiary to any customer of the Company or any Subsidiary, or to the Holder's knowledge, potential customer of the Company or any Subsidiary; (iv) directly or indirectly, on behalf of the Holder or any other person or entity, solicit, induce, recruit, hire, or encourage any employee, independent contractor, consultant, or sales representative of the Company or any Subsidiary to leave their employment; or (v) directly or indirectly, engage, or attempt to engage, on behalf of any Competitor of the Company or any Subsidiary, any customer, vendor, supplier, distributor, independent contractor, agent or other business relationship of the Company or any Subsidiary, or engage in any other action that would reasonably be expected to terminate or negatively impact any such business relationship of the Company or any Subsidiary; provided, however, that the Holder's direct or indirect ownership of less than 1% of the outstanding capital stock of a company whose capital stock is listed on a national securities exchange or regularly traded in an over-the-counter market, shall not be deemed to be a violation of this Agreement. Notwithstanding any provision of the Plan or of this Agreement to the contrary, any violation of this section by the Holder shall result in the immediate forfeiture and cancellation of the portion of the Award which is not vested as of such date.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)The Holder agrees that money damages would not be a sufficient remedy for any breach of this Section 5.2 by the Holder and that, in addition to all other remedies which may be available to the Company, the Company shall be entitled to specific performance and injunctive or other equitable relief as a remedy for any such breach. The Holder further agrees to

------

waive any requirement for the securing or posting of any bond in connection with any such remedy.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)The Holder agrees and acknowledges that (i) the services rendered by the Holder to the Company are special and of great value to the Company, (ii) the market for the Company's products and services is worldwide and the Company regularly transacts business on a worldwide basis, (iii) the covenants contained in this Section 5.2 are reasonable and necessary for the protection of the Company's legitimate business interests, (iv) the grant of the Award to the Holder is good and sufficient consideration for such covenants, and (v) the Holder's compliance with such covenants will not preclude or unreasonably restrict the Holder from engaging in other activities for the purpose of earning a livelihood.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)As used herein, (i) the term "Competitor" means any person, or entity that (A) is engaged in, or that has plans to become engaged in the research, development, manufacture, fabrication, marketing, sale or distribution of products or services that are the same as, or serve a substantially similar purpose or function as any products or services that were researched, developed, manufactured, fabricated, marketed, sold, or distributed by any business unit of the Company or any Subsidiary for which the Holder performed any work or services at any time during the last twenty-four (24) months during which the Holder was employed by Company or any Subsidiary; and (B) directly or indirectly conducts any business operations anywhere within North America or anywhere else in the world where the Holder has engaged in business activities on behalf of the Company or any Subsidiary; and (ii) the term "Covenant Period" means the period ending on the first anniversary of the date the Holder's termination of employment with the Company or any Subsidiary, regardless of the circumstances relating to such termination of employment (e.g., resignation, retirement, disability, termination by the Company for cause, or termination by the Company without cause).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.3<u>Nontransferability of Units</u>. During the Restriction Period, the Units subject to the Award and not then vested may not be transferred by the Holder other than by will, the laws of descent and distribution or pursuant to beneficiary designation procedures approved by the Company. Except to the extent permitted by the foregoing, upon any attempt to sell, transfer, assign, pledge, hypothecate or encumber, or otherwise dispose of such Units, the Award shall immediately become null and void.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.4<u>Adjustment</u>. Subject to Section 6.7 of the Plan, in the event of any stock split, stock dividend, recapitalization, reorganization, merger, consolidation, combination, exchange of shares, liquidation, spin-off or other similar change in capitalization or event, or any distribution to holders of Stock other than a regular cash dividend, or any other corporate transaction or event having an effect similar to any of the foregoing, the number and class of securities subject to the Units and the other terms of the Units shall be appropriately adjusted by the Committee. If any adjustment would result in a fractional security being subject to the Units, the Company shall pay the Holder in connection with the vesting, if any, of such fractional security an amount in cash determined by multiplying such fraction (rounded to the nearest hundredth) by the fair market value on the date of vesting. The decision of the Committee regarding any such adjustment shall be final, binding and conclusive.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.5<u>Compliance with Applicable Law</u>. The Award is subject to the condition that if the listing, registration or qualification of the Stock subject to the Units upon any securities exchange or under any law, or the consent or approval of any governmental body, or the taking

------

of any other action is necessary or desirable as a condition of, or in connection with, the vesting or delivery of Stock hereunder, the Units subject to the Award shall not vest or be delivered, in whole or in part, unless such listing, registration, qualification, consent or approval shall have been effected or obtained, free of any conditions not acceptable to the Company. The Company agrees to use reasonable efforts to effect or obtain any such listing, registration, qualification, consent or approval. Further, the Holder agrees that to the extent the issuance of Stock in the Holder's jurisdiction is impossible, illegal, unauthorized, or, in the Company's discretion, is imprudent or is otherwise impracticable for any reason, the Company may, in its discretion, either deem the Award to be a cash award of equivalent cash value or may direct the sale of all Stock subject to the Award and settle the Award in cash locally with the Holder.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.6<u>Book Entry Record/ Delivery of Certificates</u>. Subject to the foregoing paragraph, promptly following the vesting of the Units, in whole or in part, the Stock delivered at vesting shall be recorded in book entry form, unless the Company decides to deliver or cause to be delivered, subject to the withholding provisions of Section 4, one or more certificates representing the number of shares of Stock represented by the vested Units. In the event certificates are delivered, the Company shall pay all original issue or transfer taxes and all fees and expenses incident to such delivery, except as otherwise provided in Section 4.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.7<u>Award Confers No Rights to Continued Employment</u>. The granting of the Units does not entitle the Holder to any award other than that specifically granted under the Plan, nor to any future award under the Plan or any similar plan. The Award does not become part of the contract of employment or any other employment relationship with the Holder's employer, and the Award is not a guarantee of continued employment. Moreover, the Award or any future awards do not become a term or condition of employment. The Holder understands and accepts that the Units granted under the Plan are entirely at the discretion of the Company and that the Company retains the right to amend or terminate the Plan and/or the Holder's participation therein, at any time, at the Company's sole discretion and without notice. The benefits and rights provided under the Plan are not, and should not be considered part of the Holder's salary or compensation for purposes of any other calculation, including calculating any severance, resignation, redundancy or other end of service payments, vacation, bonuses, long-term service awards, indemnification, pension or retirement benefits, or any other payments, benefits or rights of any kind, except as required by applicable law. The Holder hereby waives any and all rights to compensation or damages as a result of the termination of employment with the Company for any reason whatsoever insofar as those rights result or may result from: (a) the loss or diminution in value of any rights under the Plan; or (b) the Holder ceasing to have any rights under, or ceasing to be entitled to any rights under, the Plan as a result of such termination.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.8<u>Decisions of Board or Committee</u>. The Board or the Committee shall have the right to resolve all questions which may arise in connection with the Award. Subject to the terms of the Plan, administration of ministerial, non-substantive aspects of the Award has been delegated to the Company. Any interpretation, determination or other action made or taken by the Board or the Committee, or the Company as its delegate, regarding the Plan or this Agreement shall be final, binding and conclusive.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.9<u>Incorporation of the Plan</u>. The Plan, as it exists on the date of this Agreement and as amended from time to time, is hereby incorporated by reference and made a part hereof, and the Award and this Agreement shall be subject to all terms and conditions of the Plan and any subsequent amendments to the Plan. In the event of any conflict between the provisions of this Agreement and the provisions of the Plan, the terms of the Plan shall control. The Holder hereby acknowledges receipt of a copy of the Plan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.10<u>Value of Units and Common Stock</u>. The Company makes no representation as to the value of the Units. The Company is not responsible for any fluctuations in the value of the Stock.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.11<u>Investment Representation</u>. The Holder hereby represents and covenants that (a) any Stock acquired upon the vesting of the Units will be acquired for investment and not with a view to the distribution thereof within the meaning of the Securities Act of 1933, as amended (the "Securities Act"), unless such acquisition has been registered under the Securities Act and any applicable state securities law; (b) any subsequent sale of any such Stock shall be made either pursuant to an effective registration statement under the Securities Act and any applicable state securities laws, or pursuant to an exemption from registration under the Securities Act and such state securities laws; and (c) if requested by the Company, the Holder shall submit a written statement, in form satisfactory to the Company, to the effect that such representation (i) is true and correct as of the date of acquisition of any shares hereunder or (ii) is true and correct as of the date of any sale of any such Stock, as applicable. As a further condition precedent to the delivery to the Holder of any Stock subject to the Units, the Holder shall comply with all regulations and requirements of any regulatory authority having control of or supervision over the issuance of the Stock and, in connection therewith, shall execute any documents which the Board or any committee authorized by the Board shall in its sole discretion deem necessary or advisable.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.12<u>Notices and Electronic Delivery</u>. The Company may, in its sole discretion, deliver any documents (other than certificates), notices or other communications related to the Units and the Holder's participation in the Plan by electronic means. The Holder hereby consents to receive such documents by electronic delivery and, if requested, agrees to participate in the Plan through an on-line or electronic system established and maintained by the Company or another third party designated by the Company.

&nbsp;&nbsp;&nbsp;&nbsp;Any documents, notices or other communications which are not delivered electronically pursuant to this section shall be in writing, and shall be deemed to have been duly given when received, if delivered personally, or when mailed, if sent by first class mail, postage paid, addressed as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.13<u>Deferral of Units.</u>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)<u>Deferral Election.</u> If the Holder made an election, in accordance with the terms and conditions prescribed by the Company and Section 409A of the Code and pursuant to an election form provided to the Holder by the Company, to defer the receipt of the Units that would have otherwise vested pursuant to Section 1(a), such Units shall be payable at the time and form elected by the Holder pursuant to such election.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)<u>Dividend Equivalents.</u> Until the distribution of Units deferred pursuant to this Section 5.13 (the "Deferral Period"), the Units shall continue to be credited with dividend equivalents, as described in Section 3 hereof.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.14<u>Miscellaneous.</u>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)<u>Successors</u>. This Agreement shall be binding upon and inure to the benefit of any successor or successors of the Company and any person or persons who shall, upon the death of the Holder, acquire any right hereunder in accordance with the Plan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)<u>Entire Understanding</u>. The Plan and this Agreement constitute the entire agreement and understanding between the parties with respect to the matter described herein and supersede all prior and contemporaneous agreements and understandings, oral and written, between the parties with respect to such subject matter; provided, however, that the covenants contained in Section 5.2 shall complement and shall be in addition to, and shall not supersede similar covenants made by the Holder to the Company or any Subsidiary, including covenants made in the Agreement-Protection of Owens Corning Proprietary Interests or the Intellectual Property Agreement if the Holder has executed such an agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)<u>Modification</u>. No modification or waiver of any of the provisions of this Agreement shall be effective unless in writing and signed by the party against whom it is sought to be enforced, and specifically references this Restricted Stock Unit Award Agreement by name.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e)<u>Waiver</u>. The failure of any party hereto at any time to require performance by another party of any provision of this Agreement shall not affect the right of such party to require performance of that provision, and any waiver by any party of any breach of any provision of this Agreement shall not be construed as a waiver of any continuing or succeeding breach of such provision, a waiver of the provision itself, or a waiver of any right under this Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f)<u>Fees and Expenses; Legal Compliance</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(h)<u>Data Privacy</u>. By signing this Agreement, including by way of electronic acceptance of this Agreement by means acceptable to the Company, the Holder explicitly and unambiguously consents to the collection, processing, and transfer (electronically or otherwise) of the Holder's personal data as described in this Agreement by and among, as applicable, the Company, Subsidiaries, the Holder's employer (the "Employer"), and any third parties as necessary, for the exclusive purpose of implementing, administering and managing the Holder's participation in the Plan. Moreover, the Holder explicitly acknowledges and agrees that the Company and the Employer may hold certain personal information about the Holder (including, but not limited to, the Holder's name, home address, telephone number, email address, date of birth, employment status, tax identification number, passport or other identification number, salary, nationality, job title, any Stock awarded, cancelled, purchased, exercised, vested, unvested or outstanding in the Holder's favor, and data for tax withholding purposes) for the purposes of implementing, administering and managing the Plan ("Data"). The Holder understands that Data will be transferred to third parties assisting the Company with the implementation, administration and management of the Plan. The Holder expressly authorizes such transfer to and processing by third parties. Furthermore, the Holder understands that the recipients of the Data may be located in the United States or elsewhere, and that the recipients' country (e.g., the United States) may have different data privacy laws and protections than the Holder's country. The Holder explicitly consents to the transfer of the Holder's personal data to countries other than the Holder's country of employment. The Company will take reasonable measures to keep the Holder's personal data private, confidential, and accurate. The Holder understands that Data will be held only as long as is necessary to implement, administer and manage the Holder's participation in the Plan.

The Holder understands, however, that refusing or withdrawing the Holder's consent may affect the Holder's ability to participate in the Plan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(j)<u>Whistleblowers</u>. For the avoidance of doubt, notwithstanding anything to the contrary in the Plan, this Agreement or in any other agreement, contract or arrangement with the Company or any Subsidiary or affiliate, or in any policy, procedure or practice of the Company or any Subsidiary or affiliate (collectively, the "Arrangements"), nothing in the Arrangements or otherwise limits the Holder's right to any monetary award offered by a government-administered whistleblower award program for providing information directly to a government agency (including the Securities and Exchange Commission pursuant to Section 21F of the Exchange Act, the Dodd-Frank Wall Street Reform and Consumer Protection Act or The Sarbanes-Oxley Act of 2002, or any comparable government agency pursuant to any comparable legislation in non-U.S. jurisdictions).

The Company shall at all times prior to the expiration or termination of the Units reserve and keep available, either in its treasury or out of its authorized but unissued Stock, the full number of shares of Stock subject to the Units from time to time.

This Agreement and the Plan shall be administered in a manner consistent with this intent, and any provision that would cause this Agreement or the Plan to fail to satisfy Section 409A of the Code shall have no force and effect until amended to comply with Section 409A of the Code (which amendment may be retroactive to the extent permitted by Section 409A of the Code and may be made by the Company without the consent of the Holder).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii)To the extent the Holder has a right to receive payment pursuant to this Agreement, the payment is deferred compensation subject to Section 409A, and the event triggering the right to payment does not constitute a permitted distribution event under Section 409A(a)(2) of the Code, then notwithstanding anything to the contrary in this Agreement, issuance of cash or Stock in payment of the vested Units will be made to the Holder, to the extent necessary to comply with Section 409A of the Code, on the earliest of: (A) the last day of the Restriction Period; (B) the Holder's "separation from service" with the Company (determined in accordance with Section 409A of the Code), provided, that if the Holder is a "specified employee" (within the meaning of Section 409A of the Code), the Holder's date of payment of the Award pursuant to this clause (ii) shall be the date that is the first business day following six months after the date of the Holder's separation of service with the Company; (C) the Holder's death; (D) the Holder's permanent disability (within the meaning of Section 409A(a)(2)(C) of the Code); or (E) a change in control event (within the meaning of Section 409A of the Code).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(m)<u>Severability</u>. If any covenant or other term in this Agreement (including without limitation any covenant in Section 5.2 hereof) is determined by a court of competent jurisdiction to be wholly or partially unenforceable, the Holder agrees that: (i) this Agreement or any portion hereof may be reformed so that such covenant or other term is enforceable to the maximum extent permitted by law; (ii) such determination shall not be a bar to or in any way diminish the Company's right to enforce any such covenant or other term in any other jurisdiction; and (iii) the unaffected provisions of this Agreement shall be unimpaired and shall remain in full force and effect. Without limiting the generality of the foregoing, if any covenant in this Agreement shall be determined by a court of competent jurisdiction to be unenforceable by reason of its extending for too great a period of time or over too great a geographical area or by reason of its being too extensive in any other respect, it will be interpreted to extend only over the maximum period of time for which it may be enforceable, over the maximum geographical area as to which it may be enforceable, or to the maximum extend in all other respect as to which it may be enforceable, all as determined by such court.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.15<u>Provisions Relating to Participants in Specific U.S. States</u>. Notwithstanding any provisions in this Agreement, the Award shall also be subject to the special terms and conditions set forth in the U.S. State-Specific Addendum attached as <u>Appendix A</u> to this Agreement if the Holder is employed and/or resides in specific states or if the Company determines that the application of such terms and conditions is necessary or advisable in order to comply with applicable law. The U.S. State-Specific Addendum attached hereto as <u>Appendix A</u> constitutes part of this Agreement.

pursuant to the

**OWENS CORNING**

**2023 STOCK PLAN**

**RESTRICTED STOCK UNIT AWARD**

&nbsp;&nbsp;&nbsp;&nbsp;OWENS CORNING, a Delaware corporation (the "Company"), has granted to **#ParticipantName#** (the "Holder"), as of **#GrantDate#** (the "Grant Date"), pursuant to the provisions of the Owens Corning 2023 Stock Plan (the "Plan"), **#QuantityGranted#** restricted stock units (the "Units") relating to shares of common stock, $0.01 par value, of the Company ("Stock"), upon and subject to the restrictions, terms and conditions set forth below and in the Plan (the "Award"). Each Unit shall provide for the issuance and transfer to the Holder of one share of Stock upon the lapse of the restrictions set forth in Section 1 hereof. Upon issuance and transfer of the Stock subject to the Units following the lapse of the Restriction Period, the Holder shall have all rights incident to ownership of such Stock, including, but not limited to, voting rights and the right to receive dividends. References to employment by the Company shall also mean employment by a Subsidiary. Capitalized terms not defined herein shall have the meanings specified in the Plan.

1.<u>Restriction Period and Vesting</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)<u>General</u>. Subject to Sections 1(b) and 1(c), the Units shall vest and the restrictions shall lapse with respect to 33.3% of the Units on each anniversary of the Grant Date (each such anniversary, a "Vesting Date") until the Units are fully vested (such three-year period, the "Restriction Period"). As used herein, the term "vest" shall mean no longer subject to a substantial risk of forfeiture.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)<u>Death or Disability</u>. Notwithstanding Section 1(a), if, prior to the end of the Restriction Period, the Holder's employment with the Company terminates by reason of death or Disability, the Units that are then unvested shall vest in full, and the restrictions shall lapse, as of the date of such termination.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)<u>Change in Control</u>. Notwithstanding Sections 1(a) and 1(b), in the event of a Change in Control, as defined in the Plan, the Units shall immediately vest in full and the restrictions shall lapse as provided in Section 6.8 of the Plan; provided, however, that in the event that (i) the Units constitute the payment of nonqualified deferred compensation within the meaning of Section 409A of the Internal Revenue Code of 1986, as amended (the "Code"), and (ii) the Change in Control does not constitute a "change in control event" within the meaning of Section 409A of the Code, the Units shall not immediately vest upon such Change in Control, but instead shall vest and be payable in accordance with the vesting schedule set forth in clause (i) of Section 1(a) hereof, or earlier pursuant to Section 1(b) hereof.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)<u>Forfeiture</u>. If, prior to the end of the Restriction Period, the Holder's employment with the Company terminates for any reason other than death or Disability, the Units that are

------

then unvested as of the effective date of the termination of the Holder's employment shall be forfeited by the Holder and such portion shall thereafter be cancelled by the Company.

2.<u>Settlement of Award</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)<u>General</u>. Subject to Section 2(b), one share of Stock will be issued as payment for each Unit that vests pursuant to Section 1(a) within 30 days following the end of the Restriction Period.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)<u>Other Payment Events</u>. Notwithstanding Section 2(a), to the extent the Units are vested on the dates set forth below, payment with respect to the vested Units will be made as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i)<u>Death or Disability</u>. Within 30 days of the date of the termination of the Holder's employment with the Company by reason of the Holder's death or Disability, one share of Stock will be issued as payment for each Unit, if any, that vests pursuant to Section 1(b).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii)<u>Change in Control</u>. Within 30 days of a Change in Control, one share of Stock will be issued as payment for each Unit, if any, that vests pursuant to Section 1(c).

3.<u>Rights as a Stockholder and Dividend Equivalents</u>.

During the Restriction Period, the Holder shall not be a stockholder of record with respect to the Stock underlying any unvested Units and shall have no voting rights with respect to such Stock. With respect to each of the Units covered by this Agreement, the Holder shall be credited on the records of the Company with dividend equivalents in an amount equal to the amount per share of Stock of any cash dividends declared by the Board on the outstanding Stock (and the applicable record date occurring) during the period beginning on the Grant Date and ending either on the date on which the Holder receives payment for the Units pursuant to Section 2 hereof or at the time when the Units are forfeited in accordance with Section 1(d) of this Agreement. These dividend equivalents will accumulate without interest and, subject to the terms and conditions of this Agreement, will be paid at the same time, to the same extent and in the same manner, in cash, as the Units for which the dividend equivalents were credited. If the Award is subject to a deferral election as described in Section 5.13 below, dividend equivalents will be accrued in the form of additional Units, with the increase in the number of Units equal to the number of shares of Stock or fractional shares of Stock that could be purchased with the dividends based on the value of the Stock at the time such dividends are paid ("Credited Units"). Such Credited Units shall be subject to the restrictions set forth in Section 1 hereof and shall be paid to the Holder in the time and manner as provided in their deferral election.

4.<u>Withholding Taxes</u>.

To the extent that the Company or a Subsidiary is required to withhold federal, state, local, employment, or foreign taxes or other amounts, or, to the extent permitted under Section 409A of the Code, any other applicable taxes (the "Required Tax Payments"), in connection with the Holder's right to receive shares of Stock under this Agreement (regardless of whether the

------

Holder is entitled to the delivery of any Stock at that time), and the amounts available to the Company for such withholding are insufficient, as a condition precedent to the delivery to the Holder of any such Stock upon the vesting of the Units, the Holder agrees that the Required Tax Payments shall be satisfied by the Company withholding from the Stock otherwise to be delivered to the Holder pursuant to the Award having a Fair Market Value, determined as of the date of taxation, equal to the Required Tax Payments.

No payments in respect of vested Units shall be delivered to the Holder until the Required Tax Payments have been satisfied in full.

5.<u>Additional Terms and Conditions of Award</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.1<u>Award Subject to Acceptance of Agreement</u>. The Award shall be null and void unless the Holder shall accept this Agreement by executing it in an enforceable manner, including through an electronic acceptance, in such form as is determined to be acceptable within the discretion of the Committee.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.2<u>Agreement Not To Compete and Not To Solicit.</u>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)In exchange for the consideration provided by the Company in this Agreement, the Holder agrees that, during the Covenant Period, the Holder shall not, without the prior written consent of the Company: (i) become directly or indirectly engaged or involved, as an owner, principal, employee, officer, director, manager, independent contractor, consultant, representative, seller, distributor, agent, advisor, lender or in any other capacity, with or for any Competitor of the Company or any Subsidiary; (ii) participate in the research or development, manufacture, and/or any business, fabrication, marketing, sale or distribution of any products or services that are competitive with or similar to any products or services then being developed, manufactured, fabricated, marketed, sold or distributed by the Company or any Subsidiary; (iii) directly or indirectly, on behalf of the Holder or any other person or entity, offer, market, sell or distribute, or participate in offering, marketing, selling or distributing any products or services that are competitive with or similar to any products or services then offered, marketed, sold or distributed by the Company or any Subsidiary to any customer of the Company or any Subsidiary, or to the Holder's knowledge, potential customer of the Company or any Subsidiary; (iv) directly or indirectly, on behalf of the Holder or any other person or entity, solicit, induce, recruit, hire, or encourage any employee, independent contractor, consultant, or sales representative of the Company or any Subsidiary to leave their employment; or (v) directly or indirectly, engage, or attempt to engage, on behalf of any Competitor of the Company or any Subsidiary, any customer, vendor, supplier, distributor, independent contractor, agent or other business relationship of the Company or any Subsidiary, or engage in any other action that would reasonably be expected to terminate or negatively impact any such business relationship of the Company or any Subsidiary; provided, however, that the Holder's direct or indirect ownership of less than 1% of the outstanding capital stock of a company whose capital stock is listed on a national securities exchange or regularly traded in an over-the-counter market, shall not be deemed to be a violation of this Agreement. Notwithstanding any provision of the Plan or of this Agreement to the contrary, any violation of this section by the Holder shall result in the immediate forfeiture and cancellation of the portion of the Award which is not vested as of such date.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)The Holder agrees that money damages would not be a sufficient remedy for any breach of this Section 5.2 by the Holder and that, in addition to all other remedies which may be available to the Company, the Company shall be entitled to specific performance and injunctive or other equitable relief as a remedy for any such breach. The Holder further agrees to

------

waive any requirement for the securing or posting of any bond in connection with any such remedy.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)The Holder agrees and acknowledges that (i) the services rendered by the Holder to the Company are special and of great value to the Company, (ii) the market for the Company's products and services is worldwide and the Company regularly transacts business on a worldwide basis, (iii) the covenants contained in this Section 5.2 are reasonable and necessary for the protection of the Company's legitimate business interests, (iv) the grant of the Award to the Holder is good and sufficient consideration for such covenants, and (v) the Holder's compliance with such covenants will not preclude or unreasonably restrict the Holder from engaging in other activities for the purpose of earning a livelihood.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)As used herein, (i) the term "Competitor" means any person, or entity that (A) is engaged in, or that has plans to become engaged in the research, development, manufacture, fabrication, marketing, sale or distribution of products or services that are the same as, or serve a substantially similar purpose or function as any products or services that were researched, developed, manufactured, fabricated, marketed, sold, or distributed by any business unit of the Company or any Subsidiary for which the Holder performed any work or services at any time during the last twenty-four (24) months during which the Holder was employed by Company or any Subsidiary; and (B) directly or indirectly conducts any business operations anywhere within North America or anywhere else in the world where the Holder has engaged in business activities on behalf of the Company or any Subsidiary; and (ii) the term "Covenant Period" means the period ending on the first anniversary of the date the Holder's termination of employment with the Company or any Subsidiary, regardless of the circumstances relating to such termination of employment (e.g., resignation, retirement, disability, termination by the Company for cause, or termination by the Company without cause).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.3<u>Nontransferability of Units</u>. During the Restriction Period, the Units subject to the Award and not then vested may not be transferred by the Holder other than by will, the laws of descent and distribution or pursuant to beneficiary designation procedures approved by the Company. Except to the extent permitted by the foregoing, upon any attempt to sell, transfer, assign, pledge, hypothecate or encumber, or otherwise dispose of such Units, the Award shall immediately become null and void.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.4<u>Adjustment</u>. Subject to Section 6.7 of the Plan, in the event of any stock split, stock dividend, recapitalization, reorganization, merger, consolidation, combination, exchange of shares, liquidation, spin-off or other similar change in capitalization or event, or any distribution to holders of Stock other than a regular cash dividend, or any other corporate transaction or event having an effect similar to any of the foregoing, the number and class of securities subject to the Units and the other terms of the Units shall be appropriately adjusted by the Committee. If any adjustment would result in a fractional security being subject to the Units, the Company shall pay the Holder in connection with the vesting, if any, of such fractional security an amount in cash determined by multiplying such fraction (rounded to the nearest hundredth) by the fair market value on the date of vesting. The decision of the Committee regarding any such adjustment shall be final, binding and conclusive.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.5<u>Compliance with Applicable Law</u>. The Award is subject to the condition that if the listing, registration or qualification of the Stock subject to the Units upon any securities exchange or under any law, or the consent or approval of any governmental body, or the taking

------

of any other action is necessary or desirable as a condition of, or in connection with, the vesting or delivery of Stock hereunder, the Units subject to the Award shall not vest or be delivered, in whole or in part, unless such listing, registration, qualification, consent or approval shall have been effected or obtained, free of any conditions not acceptable to the Company. The Company agrees to use reasonable efforts to effect or obtain any such listing, registration, qualification, consent or approval. Further, the Holder agrees that to the extent the issuance of Stock in the Holder's jurisdiction is impossible, illegal, unauthorized, or, in the Company's discretion, is imprudent or is otherwise impracticable for any reason, the Company may, in its discretion, either deem the Award to be a cash award of equivalent cash value or may direct the sale of all Stock subject to the Award and settle the Award in cash locally with the Holder.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.6<u>Book Entry Record/ Delivery of Certificates</u>. Subject to the foregoing paragraph, promptly following the vesting of the Units, in whole or in part, the Stock delivered at vesting shall be recorded in book entry form, unless the Company decides to deliver or cause to be delivered, subject to the withholding provisions of Section 4, one or more certificates representing the number of shares of Stock represented by the vested Units. In the event certificates are delivered, the Company shall pay all original issue or transfer taxes and all fees and expenses incident to such delivery, except as otherwise provided in Section 4.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.7<u>Award Confers No Rights to Continued Employment</u>. The granting of the Units does not entitle the Holder to any award other than that specifically granted under the Plan, nor to any future award under the Plan or any similar plan. The Award does not become part of the contract of employment or any other employment relationship with the Holder's employer, and the Award is not a guarantee of continued employment. Moreover, the Award or any future awards do not become a term or condition of employment. The Holder understands and accepts that the Units granted under the Plan are entirely at the discretion of the Company and that the Company retains the right to amend or terminate the Plan and/or the Holder's participation therein, at any time, at the Company's sole discretion and without notice. The benefits and rights provided under the Plan are not, and should not be considered part of the Holder's salary or compensation for purposes of any other calculation, including calculating any severance, resignation, redundancy or other end of service payments, vacation, bonuses, long-term service awards, indemnification, pension or retirement benefits, or any other payments, benefits or rights of any kind, except as required by applicable law. The Holder hereby waives any and all rights to compensation or damages as a result of the termination of employment with the Company for any reason whatsoever insofar as those rights result or may result from: (a) the loss or diminution in value of any rights under the Plan; or (b) the Holder ceasing to have any rights under, or ceasing to be entitled to any rights under, the Plan as a result of such termination.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.8<u>Decisions of Board or Committee</u>. The Board or the Committee shall have the right to resolve all questions which may arise in connection with the Award. Subject to the terms of the Plan, administration of ministerial, non-substantive aspects of the Award has been delegated to the Company. Any interpretation, determination or other action made or taken by the Board or the Committee, or the Company as its delegate, regarding the Plan or this Agreement shall be final, binding and conclusive.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.9<u>Incorporation of the Plan</u>. The Plan, as it exists on the date of this Agreement and as amended from time to time, is hereby incorporated by reference and made a part hereof, and the Award and this Agreement shall be subject to all terms and conditions of the Plan and any subsequent amendments to the Plan. In the event of any conflict between the provisions of this Agreement and the provisions of the Plan, the terms of the Plan shall control. The Holder hereby acknowledges receipt of a copy of the Plan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.10<u>Value of Units and Common Stock</u>. The Company makes no representation as to the value of the Units. The Company is not responsible for any fluctuations in the value of the Stock.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.11<u>Investment Representation</u>. The Holder hereby represents and covenants that (a) any Stock acquired upon the vesting of the Units will be acquired for investment and not with a view to the distribution thereof within the meaning of the Securities Act of 1933, as amended (the "Securities Act"), unless such acquisition has been registered under the Securities Act and any applicable state securities law; (b) any subsequent sale of any such Stock shall be made either pursuant to an effective registration statement under the Securities Act and any applicable state securities laws, or pursuant to an exemption from registration under the Securities Act and such state securities laws; and (c) if requested by the Company, the Holder shall submit a written statement, in form satisfactory to the Company, to the effect that such representation (i) is true and correct as of the date of acquisition of any shares hereunder or (ii) is true and correct as of the date of any sale of any such Stock, as applicable. As a further condition precedent to the delivery to the Holder of any Stock subject to the Units, the Holder shall comply with all regulations and requirements of any regulatory authority having control of or supervision over the issuance of the Stock and, in connection therewith, shall execute any documents which the Board or any committee authorized by the Board shall in its sole discretion deem necessary or advisable.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.12<u>Notices and Electronic Delivery</u>. The Company may, in its sole discretion, deliver any documents (other than certificates), notices or other communications related to the Units and the Holder's participation in the Plan by electronic means. The Holder hereby consents to receive such documents by electronic delivery and, if requested, agrees to participate in the Plan through an on-line or electronic system established and maintained by the Company or another third party designated by the Company.

&nbsp;&nbsp;&nbsp;&nbsp;Any documents, notices or other communications which are not delivered electronically pursuant to this section shall be in writing, and shall be deemed to have been duly given when received, if delivered personally, or when mailed, if sent by first class mail, postage paid, addressed as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)if to the Company or the Committee, to the attention of the Vice President, Total Rewards, Owens Corning World Headquarters, One Owens Corning Parkway, Toledo, Ohio 43659, or to the attention of such other person or at such other address as the Company, by notice to the Holder, may designate in writing from time to time, and

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)if to the Holder, at their address as shown on the records of the Company, or at such other address as the Holder, by notice to the Company, may designate in writing from time to time.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.13<u>Deferral of Units.</u>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)<u>Deferral Election.</u> If the Holder made an election, in accordance with the terms and conditions prescribed by the Company and Section 409A of the Code and pursuant to an election form provided to the Holder by the Company, to defer the receipt of the Units that would have otherwise vested pursuant to Section 1(a), such Units shall be payable at the time and form elected by the Holder pursuant to such election.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)<u>Dividend Equivalents.</u> Until the distribution of Units deferred pursuant to this Section 5.13 (the "Deferral Period"), the Units shall continue to be credited with dividend equivalents, as described in Section 3 hereof.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.14<u>Miscellaneous.</u>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)<u>Successors</u>. This Agreement shall be binding upon and inure to the benefit of any successor or successors of the Company and any person or persons who shall, upon the death of the Holder, acquire any right hereunder in accordance with the Plan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)<u>Counterparts</u>. This Agreement may be executed in one or more counterparts, all of which taken together shall constitute one agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)<u>Entire Understanding</u>. The Plan and this Agreement constitute the entire agreement and understanding between the parties with respect to the matter described herein and supersede all prior and contemporaneous agreements and understandings, oral and written, between the parties with respect to such subject matter; provided, however, that the covenants contained in Section 5.2 shall complement and shall be in addition to, and shall not supersede similar covenants made by the Holder to the Company or any Subsidiary, including covenants made in the Agreement-Protection of Owens Corning Proprietary Interests or the Intellectual Property Agreement if the Holder has executed such an agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)<u>Modification</u>. No modification or waiver of any of the provisions of this Agreement shall be effective unless in writing and signed by the party against whom it is sought to be enforced, and specifically references this Restricted Stock Unit Award Agreement by name.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e)<u>Waiver</u>. The failure of any party hereto at any time to require performance by another party of any provision of this Agreement shall not affect the right of such party to require performance of that provision, and any waiver by any party of any breach of any provision of this Agreement shall not be construed as a waiver of any continuing or succeeding breach of such provision, a waiver of the provision itself, or a waiver of any right under this Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f)<u>Fees and Expenses; Legal Compliance</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(h)<u>Data Privacy</u>. By signing this Agreement, including by way of electronic acceptance of this Agreement by means acceptable to the Company, the Holder explicitly and unambiguously consents to the collection, processing, and transfer (electronically or otherwise) of the Holder's personal data as described in this Agreement by and among, as applicable, the Company, Subsidiaries, the Holder's employer (the "Employer"), and any third parties as necessary, for the exclusive purpose of implementing, administering and managing the Holder's participation in the Plan. Moreover, the Holder explicitly acknowledges and agrees that the Company and the Employer may hold certain personal information about the Holder (including, but not limited to, the Holder's name, home address, telephone number, email address, date of birth, employment status, tax identification number, passport or other identification number, salary, nationality, job title, any Stock awarded, cancelled, purchased, exercised, vested, unvested or outstanding in the Holder's favor, and data for tax withholding purposes) for the purposes of implementing, administering and managing the Plan ("Data"). The Holder understands that Data will be transferred to third parties assisting the Company with the implementation, administration and management of the Plan. The Holder expressly authorizes such transfer to and processing by third parties. Furthermore, the Holder understands that the recipients of the Data may be located in the United States or elsewhere, and that the recipients' country (e.g., the United States) may have different data privacy laws and protections than the Holder's country. The Holder explicitly consents to the transfer of the Holder's personal data to countries other than the Holder's country of employment. The Company will take reasonable measures to keep the Holder's personal data private, confidential, and accurate. The Holder understands that Data will be held only as long as is necessary to implement, administer and manage the Holder's participation in the Plan. The Holder further understands that the Holder may request a list with the names and addresses of any potential recipients of the Data by contacting the Holder's local human resources contact, may obtain details with respect to the collection, storage, processing and transfer of Data in relation to the Plan participation, may also request access to and updates of such Data, if needed, by contacting the Holder's local Human Resources contact, and may refuse or withdraw the consents herein, in any case without cost, by contacting in writing the Holder's local human resources contact. The Holder understands, however, that refusing or withdrawing the Holder's consent may affect the Holder's ability to participate in the Plan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i)<u>Clawback Policy</u>. The Holder hereby acknowledges and agrees that this Award and this Agreement (and any settlement of this Award) are subject to the terms and conditions of the Company's clawback policies as may be in effect from time to time (the "Compensation Recovery Policy"), and that relevant sections of this Agreement shall be deemed superseded by and subject to the terms and conditions of the Compensation Recovery Policy from and after the effective date thereof. Further, by receiving this Award, the Holder (i) consents to be bound by the terms of the Compensation Recovery Policy, as applicable, (ii) agrees and acknowledges that the Holder is obligated to and will cooperate with, and will provide any and all assistance necessary to, the Company in any effort to recover or recoup any compensation or other amounts subject to clawback or recovery pursuant to the Compensation Recovery Policy and/or applicable laws, rules, regulations, stock exchange listing standards or other Company policy, and (iii) agrees that the Company may enforce its rights under the Compensation Recovery Policy through any and all reasonable means permitted under applicable law as it deems necessary or desirable under the Compensation Recovery Policy. Such cooperation and assistance shall include (but is not limited to) executing, completing and submitting any documentation necessary, or consenting to Company action, to facilitate the recovery or recoupment by the Company from the Holder of any such compensation or other

amounts, including from the Holder's accounts or from any other compensation, to the extent permissible under Section 409A of the Code.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(j)<u>Whistleblowers</u>. For the avoidance of doubt, notwithstanding anything to the contrary in the Plan, this Agreement or in any other agreement, contract or arrangement with the Company or any Subsidiary or affiliate, or in any policy, procedure or practice of the Company or any Subsidiary or affiliate (collectively, the "Arrangements"), nothing in the Arrangements or otherwise limits the Holder's right to any monetary award offered by a government-administered whistleblower award program for providing information directly to a government agency (including the Securities and Exchange Commission pursuant to Section 21F of the Exchange Act, the Dodd-Frank Wall Street Reform and Consumer Protection Act or The Sarbanes-Oxley Act of 2002, or any comparable government agency pursuant to any comparable legislation in non-U.S. jurisdictions).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(k)<u>Company to Reserve Stock</u>. The Company shall at all times prior to the expiration or termination of the Units reserve and keep available, either in its treasury or out of its authorized but unissued Stock, the full number of shares of Stock subject to the Units from time to time.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(l)<u>Compliance with Section 409A of the Code</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i)To the extent applicable, it is intended that this Agreement and the Plan comply with, or are exempt from, the provisions of Section 409A of the Code, so that the income inclusion provisions of Section 409A(a)(1) of the Code do not apply to the Holder. This Agreement and the Plan shall be administered in a manner consistent with this intent, and any provision that would cause this Agreement or the Plan to fail to satisfy Section 409A of the Code shall have no force and effect until amended to comply with Section 409A of the Code (which amendment may be retroactive to the extent permitted by Section 409A of the Code and may be made by the Company without the consent of the Holder).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii)To the extent the Holder has a right to receive payment pursuant to this Agreement, the payment is deferred compensation subject to Section 409A, and the event triggering the right to payment does not constitute a permitted distribution event under Section 409A(a)(2) of the Code, then notwithstanding anything to the contrary in this Agreement, issuance of cash or Stock in payment of the vested Units will be made to the Holder, to the extent necessary to comply with Section 409A of the Code, on the earliest of: (A) the last day of the Restriction Period; (B) the Holder's "separation from service" with the Company (determined in accordance with Section 409A of the Code), provided, that if the Holder is a "specified employee" (within the meaning of Section 409A of the Code), the Holder's date of payment of the Award pursuant to this clause (ii) shall be the date that is the first business day following six months after the date of the Holder's separation of service with the Company; (C) the Holder's death; (D) the Holder's permanent disability (within the meaning of Section 409A(a)(2)(C) of the Code); or (E) a change in control event (within the meaning of Section 409A of the Code).

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii)Reference to Section 409A of the Code will also include any regulations, or any other guidance, promulgated with respect to such Section by the U.S. Department of the Treasury or the Internal Revenue Service.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(m)<u>Severability</u>. If any covenant or other term in this Agreement (including without limitation any covenant in Section 5.2 hereof) is determined by a court of competent jurisdiction to be wholly or partially unenforceable, the Holder agrees that: (i) this Agreement or any portion hereof may be reformed so that such covenant or other term is enforceable to the maximum extent permitted by law; (ii) such determination shall not be a bar to or in any way diminish the Company's right to enforce any such covenant or other term in any other jurisdiction; and (iii) the unaffected provisions of this Agreement shall be unimpaired and shall remain in full force and effect. Without limiting the generality of the foregoing, if any covenant in this Agreement shall be determined by a court of competent jurisdiction to be unenforceable by reason of its extending for too great a period of time or over too great a geographical area or by reason of its being too extensive in any other respect, it will be interpreted to extend only over the maximum period of time for which it may be enforceable, over the maximum geographical area as to which it may be enforceable, or to the maximum extend in all other respect as to which it may be enforceable, all as determined by such court.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.15<u>Provisions Relating to Participants in Specific U.S. States</u>. Notwithstanding any provisions in this Agreement, the Award shall also be subject to the special terms and conditions set forth in the U.S. State-Specific Addendum attached as <u>Appendix A</u> to this Agreement if the Holder is employed and/or resides in specific states or if the Company determines that the application of such terms and conditions is necessary or advisable in order to comply with applicable law. The U.S. State-Specific Addendum attached hereto as <u>Appendix A</u> constitutes part of this Agreement.
