Parsons Corporation and Subsidiaries

Notes to Consolidated Financial Statements (unaudited)

1.Description of Operations

Organization

Parsons Corporation, a Delaware corporation, and its subsidiaries (collectively, the “Company”) provide sophisticated design, engineering and technical services, and smart and agile software to the United States federal government and Critical Infrastructure customers worldwide. The Company performs work in various foreign countries through local subsidiaries, joint ventures and foreign offices maintained to carry out specific projects.

2.Basis of Presentation and Principles of Consolidation

The accompanying unaudited consolidated financial statements and related notes of the Company have been prepared in accordance with generally accepted accounting principles in the United States of America ("GAAP") and pursuant to the interim period reporting requirements of Form 10-Q. They do not include all of the information and footnotes required by GAAP for complete financial statements and, therefore, should be read in conjunction with our consolidated financial statements and the notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023.

In the opinion of management, the consolidated financial statements reflect all normal recurring adjustments necessary for a fair statement of the financial position, results of operations and cash flows for the interim periods presented. The results of operations and cash flows for any interim period are not necessarily indicative of results for the full year or for future years.

This Quarterly Report on Form 10-Q includes the accounts of Parsons Corporation and its subsidiaries and affiliates which it controls. Interests in joint ventures that are controlled by the Company, or for which the Company is otherwise deemed to be the primary beneficiary, are consolidated. For joint ventures in which the Company does not have a controlling interest, but exerts a significant influence, the Company applies the equity method of accounting (see “Note 14 – Investments in and Advances to Joint Ventures" for further discussion). Intercompany accounts and transactions are eliminated in consolidation. Certain amounts may not foot due to rounding.

Use of Estimates

The preparation of the consolidated financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual amounts could differ from those estimates. The Company’s most significant estimates and judgments involve revenue recognition with respect to the determination of the costs to complete contracts and transaction price; determination of self-insurance reserves; useful lives of property and equipment and intangible assets; valuation of deferred income tax assets and uncertain tax positions, among others. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Critical Accounting Policies and Estimates” and “Note 2—Summary of Significant Accounting Policies” in the notes to our consolidated financial statements included in the Company’s Form 10-K for the year ended December 31, 2023, for a discussion of the significant estimates and assumptions affecting our consolidated financial statements. Estimates of costs to complete contracts are continually evaluated as work progresses and are revised when necessary. When a change in estimate is determined to have an impact on contract profit, the Company records a positive or negative adjustment to the consolidated statement of income.

3.New Accounting Pronouncements

In the fourth quarter of 2023, The Financial Accounting Standards Board ("FASB") Issued Accounting Standards Update (“ASU”) 2023-09, "Income Taxes (Topic 740)" ("ASU 2023-09"). ASU 2023-09 enhances the transparency and decision usefulness of income tax disclosures. The amendments in ASU 2023-09 addresses investor requests for more transparency about income tax information through improvements to income tax disclosures primarily related to the rate reconciliation and income taxes paid information. ASU 2023-09 also includes certain other amendments to improve the effectiveness of income tax disclosures. ASU 2023-09 is effective for fiscal years beginning after December 15, 2024.

6

Early adoption is permitted. The adoption of this ASU will not have a material impact on the Company's consolidated financial statements.

In the fourth quarter of 2023, the FASB Issued ASU 2023-07, "Segment Reporting (Topic 280)". ASU 2023-07 introduces enhanced disclosures about significant segment expenses along with other enhanced segment disclosures. ASU 2023-07 is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. The adoption of this ASU will not have a material impact on the Company's consolidated financial statements.

During July 2023, the FASB Issued ASU 2023-03. ASU 2023-03 incorporates, into certain accounting standards, amendments to SEC paragraphs pursuant to SEC Staff Accounting Bulletin No. 120, SEC Staff Announcement at the March 24, 2022 EITF meeting, and Staff Accounting Bulletin Topic 6.B, Accounting Series Release 280—General Revisions of Regulation S-X: Income or Loss Applicable to Common Stock. These rules are effective immediately. The adoption of this ASU did not have a material impact on the Company's consolidated financial statements.

4.Acquisitions

I.S. Engineers, LLC

On October 31, 2023, the Company entered into a Membership Interest Purchase Agreement to acquired a 100% ownership interest in I.S. Engineers, LLC (“I.S. Engineers”), a privately-owned company, for $12.2 million in cash. Headquartered in Texas, I.S. Engineers provides full service consulting specializing in transportation engineering, including roads and highways, and program management. The acquisition was entirely funded by cash on-hand. In connection with this acquisition, the Company recognized $0.3 million of acquisition related “Selling, general and administrative expense” in the consolidated statements of income for the year ended December 31, 2023, including legal fees, consulting fees, and other miscellaneous direct expenses associated with the acquisition. The Company allocated the purchase price to the appropriate classes of tangible assets and liabilities and assigned the excess of $11.9 million entirely to goodwill. The entire value of goodwill was assigned to the Critical Infrastructure reporting unit and represents synergies expected to be realized from this business combination. No goodwill is deductible for income tax purposes.

Sealing Technologies, Inc.

On August 23, 2023, the Company acquired a 100% ownership interest in Sealing Technologies, Inc (“SealingTech”), a privately-owned company, for $179.3 million in cash and up to an additional $25 million in the event an earn out revenue target is exceeded. The Company borrowed $175 million under the Credit Agreement to fund the acquisition. Headquartered in Maryland, SealingTech expands Parsons’ customer base across the Department of Defense and Intelligence Community, and further enhances the company’s capabilities in defensive cyber operations; integrated mission-solutions powered by artificial intelligence (AI) and machine learning (ML); edge computing and edge access modernization; critical infrastructure protection; and secure data management. In connection with this acquisition, the Company recognized $3.3 million of acquisition-related expenses in “Selling, general and administrative expense” in the consolidated statements of income for the year ended December 31, 2023, including legal fees, consulting fees, and other miscellaneous direct expenses associated with the acquisition.

The Company has agreed to pay the selling shareholders up to an additional $25 million in the event an earn out revenue target of $110 million is exceeded during the fiscal year ended December 31, 2024. The earn out payment due and payable by the Company to the selling shareholders shall be equal to (i) five-tenths (0.5), multiplied by (ii) the difference of (A) the actual earn out revenue minus (B) the earn out revenue target; provided, however, that in no event shall the earn out payment exceed $25 million. In the event that the earn out revenue is less than or equal to the earn out revenue target, the earn out payment shall be zero. The earn out payment, if any, shall be paid by the Company to the selling shareholders within 15 days following the date the earn out statement becomes final and binding on both parties. The fair value of the earn out (contingent consideration in the table below) was calculated using a Black-Scholes model. See “Note 2—Summary of Significant Accounting Policies” in the notes to our consolidated financial statements included in the Company’s Form 10-K for the year ended December 31, 2023 for further information on how the fair value of contingent consideration is determined.

The following table summarizes the acquisition date fair value of the purchase consideration transferred (in thousands):

	Amount
Cash paid at closing	$	179,259
Fair value of contingent consideration to be achieved		3,231
Total purchase price	$	182,490

The estimated fair value of the SealingTech contingent consideration as of March 31, 2024 was $4.1 million, a $1.8 million increase from the estimated fair value as of December 31, 2023. The change in the estimated fair value was recorded to "other income (expense), net" in the consolidated financial statements.

Transaction Price Allocated to the Remaining Unsatisfied Performance Obligations

The Company’s remaining unsatisfied performance obligations (“RUPO”) as of March 31, 2024 represent a measure of the total dollar value of work to be performed on contracts awarded and in-progress. The Company had $6.3 billion in RUPO as of March 31, 2024.

RUPO will increase with awards of new contracts and decrease as the Company performs work and recognizes revenue on existing contracts. Projects are included within RUPO at such time the project is awarded and agreement on contract terms has been reached. The difference between RUPO and backlog relates to unexercised option years that are included within backlog and the value of Indefinite Delivery/Indefinite Quantity (“IDIQ”) contracts included in backlog for which delivery orders have not been issued.

RUPO is comprised of: (a) original transaction price, (b) change orders for which written confirmations from our customers have been received, (c) pending change orders for which the Company expects to receive confirmations in the ordinary course of business, and (d) claim amounts that the Company has made against customers for which it has determined that it has a legal basis under existing contractual arrangements and a significant reversal of revenue is not probable, less revenue recognized to-date.

Delayed Draw Term Loan

In September 2022, the Company entered into a $350 million unsecured Delayed Draw Term Loan with an increase option of up to $150 million (the “2022 Delayed Draw Term Loan”). Proceeds of the 2022 Delayed Draw Term Loan Agreement may be used (a) to pay off in full, or partially payoff, the Company’s existing Senior Notes, (b) to prepay revolving loans outstanding under the Revolving Credit Agreement (as defined below), or (c) for working capital, capital expenditures and other lawful corporate purposes. The Company drew $350.0 million from the 2022 Delayed Draw Term Loan in November 2022. The Company incurred $0.9 million of debt issuance costs in connection with the delayed draw term loan. These costs are presented as a direct deduction from long-term debt on the face of the balance sheet. Interest expense related to the Delayed Draw Term Loan for the three months ended March 31, 2024 and March 31, 2023 were $6.0 million and $5.1 million, respectively. The amortization of debt issuance costs and interest expense is recorded in “Interest expense” on the consolidated statements of income. As of March 31, 2024 and December 31, 2023, there was $350.0 million outstanding under the Delayed Draw Term Loan.

14

The 2022 Delayed Draw Term Loan has a three-year maturity and permits the Company to borrow in U.S. dollars. The 2022 Delayed Draw Term Loan does not require any amortization payments by the Company. Depending on the Company’s consolidated leverage ratio (or debt rating after such time as the Company has such rating), borrowings under the 2022 Delayed Draw Term Loan Agreement will bear interest at either an adjusted Term SOFR benchmark rate plus a margin between 0.875% and 1.500% or a base rate plus a margin of between 0% and 0.500% and will initially bear interest at the middle of this range. The Company will pay a ticking fee on unused term loan commitments at a rate of 0.175% commencing with the date that is ninety (90) days after the Closing Date. Amounts outstanding under the 2022 Delayed Draw Term Loan Agreement may be prepaid at the option of the Company without premium or penalty, subject to customary breakage fees in connection with the prepayment of benchmark rate loans. The interest rates on March 31, 2024 and December 31, 2023 were 6.4% and 6.6%, respectively.

Convertible Senior Notes due 2025

In August 2020, the Company issued an aggregate $400.0 million of 0.25% Convertible Senior Notes due 2025, including the exercise of a $50.0 million initial purchasers’ option. The Company received proceeds from the issuance and sale of the Convertible Senior Notes of $389.7 million, net of $10.3 million of transaction fees and other third-party offering expenses. The Convertible Senior Notes accrue interest at a rate of 0.25% per annum, payable semi-annually on February 15 and August 15 of each year beginning on February 15, 2021, and will mature on August 15, 2025, unless earlier repurchased, redeemed or converted.

The Convertible Senior Notes are the Company’s senior unsecured obligations and will rank senior in right of payment to any of the Company’s indebtedness that is expressly subordinated in right of payment to the Notes; equal in right of payment to any of the Company’s unsecured indebtedness that is not so subordinated; effectively junior in right of payment to any of the Company’s secured indebtedness, to the extent of the value of the assets securing such indebtedness; and structurally junior to all indebtedness and other liabilities (including trade payables) of the Company’s subsidiaries

Each $1,000 of principal of the Notes will initially be convertible into 22.2913 shares of our common stock, which is equivalent to an initial conversion price of $44.86 per share, subject to adjustment upon the occurrence of specified events. On or after March 15, 2025 until the close of business on the second scheduled trading day immediately preceding the maturity date of the Convertible Senior Notes, holders may convert all or a portion of their Convertible Senior Notes, regardless of the conditions below.

Prior to the close of business on the business day immediately preceding March 15, 2025, the Notes will be convertible at the option of the holders thereof only under the following circumstances:

•during any calendar quarter commencing after the calendar quarter ending on December 31, 2021, if the last reported sale price of the Company’s common stock for at least 20 trading days, whether or not consecutive, during a period of 30 consecutive trading days ending on, and including the last trading day of the immediately preceding calendar quarter, is greater than or equal to 130% of the conversion price on each applicable trading day;

•during the five business day period after any five consecutive trading day period in which, for each trading day of that period, the trading price per $1,000 principal amount of Convertible Senior Notes for such trading day was less than 98% of the product of the last reported sale price of the Company’s common stock and the conversion rate on each such trading day;

•if the Company calls such Convertible Senior Notes for redemption; or

•upon the occurrence of specified corporate events described in the Indenture.

15

The Company may redeem all or any portion of the Convertible Senior Notes for cash, at its option, on or after August 21, 2023 and before the 51st scheduled trading day immediately before the maturity date at a redemption price equal to 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest, but only if the last reported sale price per share of the Company’s common stock exceeds 130% of the conversion price for a specified period of time. In addition, calling any Convertible Senior Note for redemption will constitute a Make-Whole Fundamental Change with respect to that Convertible Senior Note, in which case the conversion rate applicable to the conversion of that Convertible Senior Note will be increased in certain circumstances if it is converted after it is called for redemption.

Upon the occurrence of a fundamental change prior to the maturity date of the Convertible Senior Notes, holders of the Convertible Senior Notes may require the Company to repurchase all or a portion of the Convertible Senior Notes for cash at a price equal to 100% of the principal amount of the Convertible Senior Notes to be repurchased, plus any accrued and unpaid interest to, but excluding, the fundamental change repurchase date.

Upon conversion, the Company may settle the Convertible Senior Notes for cash, shares of the Company’s common stock, or a combination thereof, at the Company’s option. If the Company satisfies its conversion obligation solely in cash or through payment and delivery of a combination of cash and shares of the Company’s common stock, the amount of cash and shares of common stock due upon conversion will be based on a daily conversion value calculated on a proportionate basis for each trading day in a 50-trading day observation period.

The Company recognized interest expense of $3.7 million and $0.8 million for the three months ended March 31, 2024 and March 31, 2023, respectively. The net, carrying value of the Convertible Senior Notes were $115.4 million and $396.5 million as of March 31, 2024 and December 31, 2023, respectively.

See the discussion of the partial repurchase of Convertible Senior Notes due 2025 and the unwind of the related note hedge and warrants below.

Note Hedge and Warrant - Convertible Senior Notes due 2025

In connection with the sale of the Convertible Senior Notes, the Company purchased a bond hedge designed to mitigate the potential dilution from the conversion of the Convertible Senior Notes. Under the five-year term of the bond hedge, upon a conversion of the bonds, the Company will receive the number of shares of common stock equal to the remaining common stock deliverable upon conversion of the Convertible Senior Notes if the conversion value exceeds the principal amount of the Notes. The aggregate number of shares that the Company could be obligated to issue upon conversion of the Convertible Senior Notes is approximately 8.9 million shares. The cost of the convertible note hedge transactions was $55.0 million.

The cost of the convertible note hedge was partially offset by the Company’s sale of warrants to acquire approximately 8.9 million shares of the Company’s common stock. The warrants were initially exercisable at a price of at least $66.46 per share and are subject to customary adjustments upon the occurrence of certain events, such as the payment of dividends. The Company received $13.8 million in cash proceeds from the sales of these warrants.

The bond hedge and warrant transactions effectively increased the conversion price associated with the Convertible Senior Notes during the term of these transactions from 35%, or $44.86, to 100%, or $66.46, at their issuance, thereby reducing the dilutive economic effect to shareholders upon actual conversion.

The bond hedges and warrants are indexed to, and potentially settled in, shares of the Company’s common stock. The net cost of $41.2 million for the purchase of the bond hedges and sale of the warrants was recorded as a reduction to additional paid-in capital in the consolidated balance sheets.

At issuance, the Company recorded a deferred tax liability of $16.2 million related to the Convertible Senior Notes debt discount and the capitalized debt issuance costs. The Company also recorded a deferred tax asset of $16.5 million related to the convertible note hedge transactions and the tax basis of the capitalized debt issuance costs through additional paid-in capital. The deferred tax liability and deferred tax asset were included net in “Deferred tax assets” on the consolidated balance sheets. Upon adoption of ASU 2020-06, the Company reversed the deferred tax liability of $13.9 million that the Company had recorded at issuance related to the Convertible Senior Note debt discount and recorded an additional deferred tax liability of $0.4 million related to the capitalized debt issuance costs. In addition, the Company recorded a $0.9 million adjustment to the deferred tax asset through retained earnings related to the tax effect of book accretion recorded in 2020 and reversed upon adoption.

Convertible Senior Notes due 2029

In February 2024, the Company issued an aggregate $800.0 million of 2.625% Convertible Senior Notes due 2029 (the “2029 Convertible Notes”), including the exercise of a $100.0 million initial purchasers’ option in full. The Company received proceeds from the issuance and sale of the 2029 Convertible Notes of $781.1 million, net of $18.9 million of transaction fees and other third-party offering expenses. The 2029 Convertible Notes accrue interest at a rate of 2.625% per annum, payable semi-annually on March 1 and September 1 of each year beginning on September 1, 2024, and will mature on March 1, 2029, unless earlier repurchased, redeemed or converted.

The 2029 Convertible Notes are the Company’s senior unsecured obligations and will rank senior in right of payment to any of the Company’s indebtedness that is expressly subordinated in right of payment to the 2029 Convertible Notes; equal in right of payment to any of the Company’s unsecured indebtedness that is not so subordinated; effectively junior in right of payment to any of the Company’s secured indebtedness, including borrowings under the Company’s revolving credit facility and delayed draw term loan credit facility, to the extent of the value of the assets securing such indebtedness; and structurally junior to all indebtedness and other liabilities (including trade payables) of the Company’s subsidiaries.

Each $1,000 of principal of the 2029 Convertible Notes will initially be convertible into 10.6256 shares of our common stock, which is equivalent to an initial conversion price of approximately $94.11 per share, subject to adjustment upon the occurrence of specified events. On or after October 1, 2028 until the close of business on the second scheduled trading day immediately preceding the maturity date of the 2029 Convertible Notes, holders may convert all or a portion of their 2029 Convertible Notes, regardless of the conditions below.

Prior to the close of business on the business day immediately preceding October 1, 2028, the 2029 Convertible Notes will be convertible at the option of the holders thereof only under the following circumstances:

•during any calendar quarter commencing after the calendar quarter ending on June 30, 2024, if the last reported sale price of the Company’s common stock for at least 20 trading days, whether or not consecutive, during a period of 30 consecutive trading days ending on, and including the last trading day of the immediately preceding calendar quarter, is greater than or equal to 130% of the conversion price on each applicable trading day;

•during the five business day period after any ten consecutive trading day period in which, for each trading day of that period, the trading price per $1,000 principal amount of 2029 Convertible Notes for such trading day was less than 98% of the product of the last reported sale price of the Company’s common stock and the conversion rate on each such trading day;

•if the Company calls such 2029 Convertible Notes for redemption; or

•upon the occurrence of specified corporate events described in the Indenture.

The Company may redeem all or any portion of the 2029 Convertible Notes for cash, at its option, on or after March 8, 2027 and before the 51st scheduled trading day immediately before the maturity date at a redemption price equal to 100% of the principal amount of the 2029 Convertible Notes to be redeemed, plus accrued and unpaid interest, but only if the last reported sale price per share of the Company’s common stock exceeds 130% of the conversion price for a specified period of time. In addition, calling any 2029 Convertible Notes for redemption will constitute a Make-Whole Fundamental Change with respect to that 2029 Convertible Note, in which case the conversion rate applicable to the conversion of that 2029 Convertible Notes will be increased in certain circumstances if it is converted after it is called for redemption.

Upon the occurrence of a fundamental change prior to the maturity date of the 2029 Convertible Notes, holders of the 2029 Convertible Notes may require the Company to repurchase all or a portion of the 2029 Convertible Notes for cash at a price equal to 100% of the principal amount of the 2029 Convertible Notes to be repurchased, plus any accrued and unpaid interest to, but excluding, the fundamental change repurchase date.

Upon conversion, the Company will settle the principal amount of the 2029 Convertible Notes converted in cash and will settle the remainder of the consideration owed upon conversion in cash, shares of the Company’s common stock, or a combination thereof, at the Company’s option, with such amount of cash and, if applicable, shares of common stock

17

due upon conversion based on a daily conversion value calculated on a proportionate basis for each trading day in a 50-trading day observation period.

The Company recognized interest expense with respect to the 2029 Convertible Notes of $2.4 million for the three months ended March 31, 2024. As of March 31, 2024, the net, carrying value of the 2029 Convertible Notes was $781.5 million.

Capped Call Transactions - Convertible Senior Notes due 2029

In February 2024, in connection with the offering of the 2029 Convertible Notes, the Company entered into capped call transactions (the “Capped Call Transactions”) with certain financial institutions. The Capped Call Transactions are expected generally to reduce the potential dilution to the Company’s common stock upon any conversion of the Convertible Senior Notes due 2029 and/or offset any cash payments the Company is required to make in excess of the principal amount of any converted Convertible Senior Notes due 2029, as the case may be. If, however, the market price per share of the Company’s common stock, as measured under the terms of the Capped Call Transactions, exceeds the cap price of the Capped Call Transactions, there would nevertheless be dilution and/or there would not be an offset of such cash payments, in each case, to the extent that such market price exceeds the cap price of the Capped Call Transactions.

The cap price of the Capped Call Transactions is initially $131.7575 per share, which represents a premium of 75% over the last reported sale price of the Company’s common stock of $75.29 per share on the New York Stock Exchange on February 21, 2024, and is subject to certain adjustments under the terms of the Capped Call Transactions. The cost of $88.4 million for the Capped Call Transactions was recorded as a reduction to additional paid-in capital in the consolidated balance sheets.

At issuance, the Company recorded a deferred tax asset of $22.3 million related to the Capped Call Transactions costs through additional paid-in capital. The deferred tax asset was included in Deferred tax assets in the consolidated balance sheets.

Convertible Senior Notes due 2025 Partial Repurchase and Note Hedge and Warrants Partial Unwind

In connection with the issuance of the Convertible Senior Notes due 2029, we used $391.8 million of the net proceeds to purchase approximately $228.1 million aggregate principal amount of our Convertible Senior Notes due 2025 concurrently with the offering in separate and individually negotiated transactions. In addition, we used $103.8 million to settle the repurchase of approximately $56.5 million aggregate principal amount of our Convertible Senior Notes due 2025 in a separately negotiated transaction that settled in March 2024. We also received approximately $90.6 million in cash from the note hedge counterparties for the partial termination of the existing bond hedge relating to the Convertible Senior Notes due 2025 repurchased, net of our obligations to the counterparties in connection with the partial termination of the related warrant transactions. The tax effect of $46.2 million from the partial unwind of the existing bond hedge was recognized as a reduction in additional paid-in capital in the consolidated balance sheets. The income tax payable was included in Income taxes payable in the consolidated balance sheets.

The partial repurchase resulted in a $214.2 million loss on debt extinguishment which includes a $3.2 million charge to interest expense for the acceleration of the amortization of debt issuance costs associated with the 0.25% Convertible Senior Notes due 2025. The tax effect of the debt extinguishment, excluding the interest expense, was recognized as a discrete event to the quarter giving rise to an increase in the effective tax rate and tax benefit of $49.9 million recognized in the income statement.

Revolving Credit Facility

In June 2021, the Company entered into a $650 million unsecured revolving credit facility (the “Credit Agreement”). The Company incurred $1.9 million of costs in connection with this Credit Agreement. The 2021 Credit Agreement replaced an existing Fifth Amended and Restated Credit Agreement dated as of November 15, 2017. Under the new agreement, the Company’s revolving credit facility was increased from $550 million to $650 million. The credit facility has a five-year maturity, which may be extended up to two times for periods determined by the Company and the applicable extending lenders, and permits the Company to borrow in U.S. dollars, certain specified foreign currencies, and each other currency that may be approved in accordance with the 2021 Facility. The borrowings under the Credit Agreement bear interest at either the Term SOFR rate plus a margin between 1.0% and 1.625% or a base rate (as defined in the Credit Agreement) plus a margin of between 0% and 0.625%. The rates on March 31, 2024 and December 31, 2023 were 6.6% and 6.7%, respectively. Borrowings under this Credit Agreement are guaranteed by certain Company operating

18

subsidiaries. Letters of credit commitments outstanding under this agreement aggregated to $42.1 million and $43.8 million at March 31, 2024 and December 31, 2023, respectively, which reduced borrowing limits available to the Company. Interest expense related to the Credit Agreement was $0.3 million and $0.1 million for the three months ended March 31, 2024 and March 31, 2023, respectively. There were no loan amounts outstanding under the Credit Agreement at March 31, 2024.

The Credit Agreement includes various covenants, including restrictions on indebtedness, liens, acquisitions, investments or dispositions, payment of dividends and maintenance of certain financial ratios and conditions. The Company was in compliance with these covenants at March 31, 2024 and December 31, 2023.

Letters of Credit

The Company also has in place several secondary bank credit lines for issuing letters of credit, principally for foreign contracts, to support performance and completion guarantees. Letters of credit commitments outstanding under these bank lines aggregated approximately $281.0 million and $320.7 million at March 31, 2024 and December 31, 2023, respectively.

11.Income Taxes

In 2021 the Organization for Economic Co-operation and Development (OECD) announced an inclusive Framework on Base Erosion and Profit Shifting (BEPS) including Pillar Two Model Rules defining the global minimum tax, also known as the Global Anti-Base Erosion (GloBE), which aims to ensure that multinational enterprises (MNEs) pay a 15% minimum level of tax regardless of where the MNE operates. Subsequently, multiple sets of administrative guidance have been issued. Many non-US tax jurisdictions have either recently enacted legislation to adopt components of the Pillar Two Model Rules beginning in 2024 and/or have announced their plans to enact legislation in future years. At this time, we do not expect Pillar Two to result in any material impact to the Company’s income tax provision. We are continuing to evaluate the potential impact on future periods of the Pillar Two Framework, pending enactment of legislation by individual countries.

The Company’s effective tax rate was 25.9% and 24.6% for the three months ended March 31, 2024 and March 31, 2023, respectively. The increase in the effective tax rate was due primarily to a change in jurisdictional mix of earnings, the foreign-derived intangible income (FDII) deduction, and equity-based compensation, partially offset by executive compensation subject to Section 162(m). The difference between the effective tax rate and the statutory U.S. Federal income tax rate of 21% for the three months ended March 31, 2024 primarily relates to a change in jurisdictional earnings partially resulting from a loss in partially unwinding Convertible Senior Notes, the FDII deduction, equity based compensation, and untaxed income attributable to noncontrolling interests, partially offset by rate impacts related to state income taxes and foreign withholding taxes.

As of March 31, 2024, the Company’s deferred tax assets were subject to a valuation allowance of $36.1 million primarily related to foreign net operating loss carryforwards, foreign tax credit carryforwards, and capital losses that the Company has determined are not more-likely-than-not to be realized. The factors used to assess the likelihood of realization include: the past performance of the entities, forecasts of future taxable income, future reversals of existing taxable temporary differences, and available tax planning strategies that could be implemented to realize the deferred tax assets. The ability or failure to achieve the forecasted taxable income in these entities could affect the ultimate realization of deferred tax assets.

As of March 31, 2024 and December 31, 2023, the liability for income taxes associated with uncertain tax positions was $26.7 million and $25.5 million, respectively. It is reasonably possible that the Company may realize a decrease in our uncertain tax positions of approximately $7.2 million during the next 12 months as a result of concluding various tax audits and closing tax years.

Although the Company believes its reserves for its tax positions are reasonable, the final outcome of tax audits could be materially different, both favorably and unfavorably. It is reasonably possible that certain audits may conclude in the next 12 months and that the unrecognized tax benefits the Company has recorded in relation to these tax years may change compared to the liabilities recorded for these periods.

12.Contingencies

The Company is subject to certain lawsuits, claims and assessments that arise in the ordinary course of business. Additionally, the Company has been named as a defendant in lawsuits alleging personal injuries as a result of contact with asbestos products at various project sites. Management believes that any significant costs relating to these claims will be reimbursed by applicable insurance and, although there can be no assurance that these matters will be resolved favorably, management believes that the ultimate resolution of any of these claims will not have a material adverse effect on our consolidated financial position, results of operations, or cash flows. A liability is recorded when it is both probable that a loss has been incurred and the amount of loss or range of loss can be reasonably estimated. When using a range of loss estimate, the Company records the liability using the low end of the range unless some amount within the range of loss appears at that time to be a better estimate than any other amount in the range. The Company records a corresponding receivable for costs covered under its insurance policies. Management judgment is required to determine the outcome and the estimated amount of a loss related to such matters. Management believes that there are no claims or assessments outstanding which would materially affect the consolidated results of operations or the Company’s financial position.

In September 2015, a former Parsons employee filed an action in the United States District Court for the Northern District of Alabama against us as a qui tam relator on behalf of the United States (the “Relator”) alleging violation of the False Claims Act. The plaintiff alleges that, as a result of these actions, the United States paid in excess of $1 million per month between February and September 2006 that it should have paid to another contractor, plus $2.9 million to acquire vehicles for the contractor defendant to perform its security services. The lawsuit sought (i) that we cease and desist from violating the False Claims Act, (ii) monetary damages equal to three times the amount of damages that the United States has sustained because of our alleged violations, plus a civil penalty of not less than $5,500 and not more than $11,000 for each alleged violation of the False Claims Act, (iii) monetary damages equal to the maximum amount allowed pursuant to §3730(d) of the False Claims Act, and (iv) Relator’s costs for this action, including recovery of attorneys’ fees and costs incurred in the lawsuit. The United States government did not intervene in this matter as it is allowed to do so under the statute. The court heard dispositive motions in 2023, including Parsons’ motion for summary judgment. We are awaiting the court’s rulings upon such motions, which will determine whether a trial will be necessary for this matter in 2024.

On November 28, 2023, a Proposed Statement of Decision was filed with the clerk of the Superior Court of the State of California In and For the County of San Mateo proposing an award of damages in the total amount of approximately $102.5 million in favor of Parsons Transportation Group, Inc. and against Alstom Signaling Operations LLC (Alstom") (including approximately $62.5 million relating to claims assigned to Parsons pursuant to a prior settlement with the Peninsula Corridor Joint Powers Board and approximately $40 million attributable to Parsons’ contractual and indemnification claims). This proposed award relates back to a lawsuit Parsons initially filed against the Peninsula Corridor Joint Powers Board for breach of contract and wrongful termination in February 2017 (which was settled between Parsons and the Joint Powers Board in 2021) and a cross-complaint filed against Alstom Signaling Operations LLC in November 2017, as subsequently amended, for breach of contract, negligence and intentional misrepresentation. Alstom filed objections to the Proposed Statement of Decision, and Parsons has filed its responses to the objections. The Court has scheduled a hearing upon the Objections and post-trial motions filed by Alstom in the second quarter of 2024.

At this time, the Company is unable to determine the probability of the outcome of the litigation.

Federal government contracts are subject to audits, which are performed for the most part by the Defense Contract Audit Agency (“DCAA”). Audits by the DCAA and other agencies consist of reviews of our overhead rates, operating systems and cost proposals to ensure that we account for such costs in accordance with the Cost Accounting Standards (“CAS”). If the DCAA determines we have not accounted for such costs in accordance with the CAS, the DCAA may disallow these costs. The disallowance of such costs may result in a reduction of revenue and additional liability for the Company. Historically, the Company has not experienced any material disallowed costs as a result of government audits. However, the Company can provide no assurance that the DCAA or other government audits will not result in

20

material disallowances for incurred costs in the future. All audits of costs incurred on work performed through 2018 have been closed, and years thereafter remain open.

Although there can be no assurance that these matters will be resolved favorably, management believes that their ultimate resolution will not have a material adverse impact on the Company’s consolidated financial position, results of operations, or cash flows.

13.Retirement Benefit Plan

The Company’s principal retirement benefit plan is the Parsons Employee Stock Ownership Plan (“ESOP”), a stock bonus plan, established in 1975 to cover eligible employees of the Company and certain affiliated companies. Contributions of treasury stock to the ESOP are made annually in amounts determined by the Company’s board of directors and are held in trust for the sole benefit of the participants. Shares allocated to a participant’s account are fully vested after three years of credited service, or in the event(s) of reaching age 65, death or disability while an active employee of the Company. As of March 31, 2024 and December 31, 2023, total shares of the Company’s common stock outstanding were 106,203,479 and 105,839,978, respectively, of which 57,998,295 and 59,879,857, respectively, were held by the ESOP.

A participant’s interest in their ESOP account is redeemable upon certain events, including retirement, death, termination due to permanent disability, a severe financial hardship following termination of employment, certain conflicts of interest following termination of employment, or the exercise of diversification rights. Distributions from the ESOP of participants’ interests are made in the Company’s common stock based on quoted prices of a share of the Company’s common stock on the NYSE. A participant will be able to sell such shares of common stock in the market, subject to any requirements of the federal securities laws.

Total ESOP contribution expense was $15.0 million and $14.4 million for the three months ended March 31, 2024 and March 31, 2023, respectively. The expense is recorded in “Direct costs of contracts” and “Selling, general and administrative expense” in the consolidated statements of income. The fiscal 2024 ESOP contribution has not yet been made. The amount is currently included in accrued liabilities.

14.Investments in and Advances to Joint Ventures

The Company participates in joint ventures to bid, negotiate and complete specific projects. The Company is required to consolidate these joint ventures if it holds the majority voting interest or if the Company meets the criteria under the consolidation model, as described below.

The Company performs an analysis to determine whether its variable interests give the Company a controlling financial interest in a Variable Interest Entity (“VIE”) for which the Company is the primary beneficiary and should, therefore, be consolidated. Such analysis requires the Company to assess whether it has the power to direct the activities of the VIE and the obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIE.

The Company analyzed all of its joint ventures and classified them into two groups: (1) joint ventures that must be consolidated because they are either not VIEs and the Company holds the majority voting interest, or because they are VIEs and the Company is the primary beneficiary; and (2) joint ventures that do not need to be consolidated because they are either not VIEs and the Company holds a minority voting interest, or because they are VIEs and the Company is not the primary beneficiary.

Many of the Company’s joint venture agreements provide for capital calls to fund operations, as necessary; however, such funding is infrequent and is not anticipated to be material.

Letters of credit outstanding described in “Note 10 – Debt and Credit Facilities” that relate to project ventures are $149.9 million and $147.7 million at March 31, 2024 and December 31, 2023.

In the table below, aggregated financial information relating to the Company’s joint ventures is provided because their nature, risk and reward characteristics are similar. None of the Company’s current joint ventures that meet the characteristics of a VIE are individually significant to the consolidated financial statements.

The assets of the consolidated joint ventures are restricted for use only by the particular joint venture and are not available for the Company’s general operations.

Unconsolidated Joint Ventures

The Company accounts for its unconsolidated joint ventures using the equity method of accounting. Under this method, the Company recognizes its proportionate share of the net earnings of these joint ventures as “Equity in (losses) earnings of unconsolidated joint ventures” in the consolidated statements of income. The Company’s maximum exposure to loss as a result of its investments in unconsolidated joint ventures is typically limited to the aggregate of the carrying value of the investment and future funding commitments.

The following represents the financial information of the Company’s unconsolidated joint ventures as presented in their unaudited financial statements (in thousands):

15.Related Party Transactions

The Company often provides services to unconsolidated joint ventures and revenues include amounts related to recovering costs for these services. Revenues related to services the Company provided to unconsolidated joint ventures for the three months ended March 31, 2024 and March 31, 2023 were $46.8 million and $50.9 million, respectively. For the three months ended March 31, 2024 and March 31, 2023, the Company incurred $35.4 million and $39.2 million, respectively, of reimbursable costs. The revenue and reimbursable cost prior period amounts have been updated to reflect all joint ventures for the comparable period. Amounts included in the consolidated balance sheets related to services the Company provided to unconsolidated joint ventures are as follows (in thousands):

	March 31, 2024		December 31, 2023

16.Fair Value of Financial Instruments

The authoritative guidance on fair value measurement defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (referred to as an “exit price”). At March 31, 2024 and December 31, 2023, the Company’s financial instruments include cash, cash equivalents, accounts receivable, accounts payable, and other liabilities. The fair values of these financial instruments approximate their carrying values due to their short-term maturities.

Investments measured at fair value are based on one or more of the following three valuation techniques:

•Market approach—Prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities;

•Cost approach—Amount that would be required to replace the service capacity of an asset (i.e., replacement cost); and

•Income approach—Techniques to convert future amounts to a single present amount based on market expectations (including present value techniques, option-pricing models and lattice models).

In addition, the guidance establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted market prices in active markets for identical assets and liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are:

Level 1 Unadjusted quoted prices in active markets that are accessible at the measurement date for identical assets and liabilities;

Level 2 Pricing inputs that include quoted prices for similar assets and liabilities in active markets and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the instrument; and

Level 3 Prices or valuations that require inputs that are both significant to the fair value measurements and unobservable.

The methods described above may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. Furthermore, while the Company believes its valuation methods are appropriate

23

and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date.

Financial assets and liabilities measured at fair value on a quarterly basis are as follows:

17.Earnings Per Share

Basic earnings per share (“EPS”) is computed using the weighted average number of shares outstanding during the period and income available to shareholders. Diluted EPS includes additional common shares that would have been outstanding if potential common shares with a dilutive effect had been issued using the if-converted method for Convertible Debt and the treasury stock method for all other instruments.

Under the treasury stock method, the weighted average number of shares outstanding is adjusted to reflect the dilutive effects of stock-based awards.

Under the if-converted method:

1.Convertible Senior Notes due 2025:

a.Income available to shareholders is adjusted to add back interest expense, after tax (unless antidilutive).

b.Weighted average number of shares outstanding is adjusted to include the shares underlying the convertible debt (unless antidilutive).

c.Shares underlying the bond hedge (unless antidilutive).

d.Shares underlying the warrants (unless antidilutive).

2.Convertible Senior Notes due 2029:

a.Interest has been excluded from the numerator and no shares have been included in the denominator of diluted EPS, as the principal amount of convertible debt will be settled in cash with any excess conversion value settled in cash or shares of common stock.

b.Excludes shares underlying the capped call as the shares are antidilutive.

The following tables reconcile the denominator and numerator used to compute basic EPS to the denominator and numerator used to compute diluted EPS for the three months ended March 31, 2024 and March 31, 2023 (in thousands):

Due to the loss for the three months ended March 31, 2024, stock based awards of 1.5 million shares, the potential dilution from convertible senior notes due 2025 of 6.8 million shares and convertible senior notes due 2025 interest expense of $2.8 million have been excluded from the calculation of diluted earnings per share, as their inclusion would have been antidilutive.

Anti-dilutive stock-based awards excluded from the calculation of earnings per share for the three months ended March 31, 2023 were 8,831.

Share Repurchases

On August 9, 2021, the Company’s Board of Directors authorized the Company to acquire a number of shares of Common Stock having an aggregate market value of not greater than $100 million from time to time, commencing on August 12, 2021. The Board further amended this authorization in August 2022 to remove the prior expiration date and grant executive leadership the discretion to determine the price for such share repurchases. The Board further amended this authorization in February 2024 to restore the repurchase capacity to $100 million and removed the $25 million quarterly cap on such repurchases.

At the time of the February 2024 authorization, the Company had repurchased shares with an aggregated market value (including fees) of $54.7 million. As of March 31, 2024, the Company has $100 million remaining under the stock repurchase program. The aggregate market value of shares of Common Stock the Company is authorized to acquire is now not greater than $154.7 million.

Repurchased shares of common stock are retired and included in “Repurchases of common stock” in cash flows from financing activities in the Consolidated Statements of Cash Flows. The primary purpose of the Company’s share repurchase program is to reduce the dilutive effect of shares issued under the Company’s ESOP and other stock benefit plans. The timing, amount and manner of share repurchases may depend upon market conditions and economic circumstances, availability of investment opportunities, the availability and costs of financing, the market price of the Company's common stock, other uses of capital and other factors.

There were no share repurchases during the three months ended March 31, 2024.

The following table summarizes the repurchase activity under the stock repurchase program:

18.Segment Information

The Company operates in two reportable segments: Federal Solutions and Critical Infrastructure.

The Federal Solutions segment provides advanced technical solutions to the U.S. government, delivering timely, cost-effective hardware, software and services for mission-critical projects. The segment provides advanced technologies, supporting national security missions in cybersecurity, missile defense, and military facility modernization, logistics support, hazardous material remediation and engineering services.

The Critical Infrastructure segment provides integrated engineering and management services for complex physical and digital infrastructure around the globe. The Critical Infrastructure segment is a technology innovator focused on next generation digital systems and complex structures. Industry leading capabilities in engineering and project management allow the Company to deliver significant value to customers by employing cutting-edge technologies, improving timelines and reducing costs.

The Company defines its reportable segments based on the way the chief operating decision maker (“CODM”), its Chief Executive Officer, evaluates the performance of each segment and manages the operations of the Company for purposes of allocating resources among the segments. The CODM evaluates segment operating performance using segment Revenue and segment Adjusted EBITDA attributable to Parsons Corporation.

The following table summarizes business segment revenue for the periods presented (in thousands):

	Three Months Ended

Overview

We are a leading provider of the integrated solutions and services required in today’s complex security environment and a world of digital transformation. We deliver innovative technology-driven solutions to customers worldwide. We have developed significant expertise and differentiated capabilities in key areas of cybersecurity, intelligence, missile defense, C5ISR, space, transportation, water/wastewater and environmental remediation. By combining our talented team of professionals and advanced technology, we solve complex technical challenges to enable a safer, smarter, more secure and more connected world.

We operate in two reporting segments, Federal Solutions and Critical Infrastructure. Our Federal Solutions business provides advanced technical solutions to the U.S. government. Our Critical Infrastructure business provides integrated engineering and management services for complex physical and digital infrastructure to state and local governments and large companies.

Our employees provide services pursuant to contracts that we are awarded by the customer and specific task orders relating to such contracts. These contracts are often multi-year, which provides us backlog and visibility on our revenues for future periods. Many of our contracts and task orders are subject to renewal and rebidding at the end of their term, and some are subject to the exercise of contract options and issuance of task orders by the applicable government

29

entity. In addition to focusing on increasing our revenues through increased contract awards and backlog, we focus our financial performance on margin expansion and cash flow.

Key Metrics

We manage and assess the performance of our business by evaluating a variety of metrics. The following table sets forth selected key metrics (in thousands, except Book-to-Bill):

	March 31, 2024		March 31, 2023
Awards (year to date)	$	2,082,309	$	1,382,229
Backlog (1)	$	9,028,843	$	8,365,242
Book-to-Bill (year to date)		1.4		1.2

(1)Difference between our backlog of $9.0 billion and our remaining unsatisfied performance obligations, or RUPO, of $6.3 billion, each as of March 31, 2024, is due to (i) unissued task orders and unexercised option years, to the extent their issuance or exercise is probable, as well as (ii) contract awards, to the extent we believe contract execution and funding is probable.

Awards

Awards generally represent the amount of revenue expected to be earned in the future from funded and unfunded contract awards received during the period. Contract awards include both new and re-compete contracts and task orders. Given that new contract awards generate growth, we closely track our new awards each year.

The following table summarizes the year to-date value of new awards for the periods presented below (in thousands):

	Three Months Ended
	March 31, 2024		March 31, 2023
Federal Solutions	$	1,282,640	$	695,644
Critical Infrastructure		799,669		686,585
Total Awards	$	2,082,309	$	1,382,229

The change in new awards from year to year is primarily due to ordinary course fluctuations in our business. The volume of contract awards can fluctuate in any given period due to win rate and the timing and size of the awards issued by our customers. The increase in awards for the three months ended March 31, 2024 when compared to the corresponding period last year was primarily driven by significant option period awards from a customer in our Federal Solutions segment.

Backlog

We define backlog to include the following two components:

•Funded—Funded backlog represents future revenue anticipated from orders for services under existing contracts for which funding is appropriated or otherwise authorized.

•Unfunded—Unfunded backlog represents future revenue anticipated from orders for services under existing contracts for which funding has not been appropriated or otherwise authorized.

Backlog includes (i) unissued task orders and unexercised option years, to the extent their issuance or exercise is probable, as well as (ii) contract awards, to the extent we believe contract execution and funding is probable.

30

The following table summarizes the value of our backlog at the respective dates presented below (in thousands):

	March 31, 2024		March 31, 2023
Federal Solutions:
Funded	$	1,804,251	$	1,694,740
Unfunded		3,450,328		3,175,568
Total Federal Solutions		5,254,579		4,870,308
Critical Infrastructure:
Funded		3,706,435		3,445,068
Unfunded		67,829		49,866
Total Critical Infrastructure		3,774,264		3,494,934
Total Backlog (1)	$	9,028,843	$	8,365,242

(1)Difference between our backlog of $9.0 billion and our RUPO of $6.3 billion, each as of March 31, 2024, is due to (i) unissued task orders and unexercised option years, to the extent their issuance or exercise is probable, as well as (ii) contract awards, to the extent we believe contract execution and funding is probable.

Our backlog includes orders under contracts that in some cases extend for several years. For example, the U.S. Congress generally appropriates funds for our U.S. federal government customers on a yearly basis, even though their contracts with us may call for performance that is expected to take a number of years to complete. As a result, our federal contracts typically are only partially funded at any point during their term. All or some of the work to be performed under the contracts may remain unfunded unless and until the U.S. Congress makes subsequent appropriations and the procuring agency allocates funding to the contract.

We expect to recognize $3.8 billion of our funded backlog at March 31, 2024 as revenues in the following twelve months. However, our U.S. federal government customers may cancel their contracts with us at any time through a termination for convenience or may elect to not exercise option periods under such contracts. In the case of a termination for convenience, we would not receive anticipated future revenues, but would generally be permitted to recover all or a portion of our incurred costs and fees for work performed. See “Risk Factors—Risk Relating to Our Business—We may not realize the full value of our backlog, which may result in lower than expected revenue” in the Company’s Form 10-K for the year ended December 31, 2023.

The changes in backlog in both the Federal Solutions and Critical Infrastructure segments were primarily from ordinary course fluctuations in our business and the impacts related to the Company’s awards discussed above.

Book-to-Bill

Book-to-bill is the ratio of total awards to total revenue recorded in the same period. Our management believes our book-to-bill ratio is a useful indicator of our potential future revenue growth in that it measures the rate at which we are generating new awards compared to the Company’s current revenue. To drive future revenue growth, our goal is for the level of awards in a given period to exceed the revenue booked. A book-to-bill ratio greater than 1.0 indicates that awards generated in a given period exceeded the revenue recognized in the same period, while a book-to-bill ratio of less than 1.0 indicates that awards generated in such period were less than the revenue recognized in such period. The following table sets forth the book-to-bill ratio for the periods presented below:

	Three Months Ended
	March 31, 2024		March 31, 2023
Federal Solutions		1.4		1.1
Critical Infrastructure		1.3		1.3
Overall		1.4		1.2

Factors and Trends Affecting Our Results of Operations

We believe that the financial performance of our business and our future success are dependent upon many factors, including those highlighted in this section. Our operating performance will depend upon many variables, including the success of our growth strategies and the timing and size of investments and expenditures that we choose to undertake, as well as market growth and other factors that are not within our control.

31

Government Spending

Changes in the relative mix of government spending and areas of spending growth, with shifts in priorities on homeland security, intelligence, defense-related programs, infrastructure and urbanization, and continued increased spending on technology and innovation, including cybersecurity, artificial intelligence, connected communities and physical infrastructure, could impact our business and results of operations. Cost-cutting and efficiency initiatives, current and future budget restrictions, spending cuts and other efforts to reduce government spending could cause our government customers to reduce or delay funding or invest appropriated funds on a less consistent basis or not at all, and demand for our solutions or services could diminish. Furthermore, any disruption in the functioning of government agencies, including as a result of government closures and shutdowns, could have a negative impact on our operations and cause us to lose revenue or incur additional costs due to, among other things, our inability to deploy our staff to customer locations or facilities as a result of such disruptions.

Federal Budget Uncertainty

There is uncertainty around the timing, extent, nature and effect of Congressional and other U.S. government actions to address budgetary constraints, caps on the discretionary budget for defense and non-defense departments and agencies, and the ability of Congress to determine how to allocate the available budget authority and pass appropriations bills to fund both U.S. government departments and agencies that are, and those that are not, subject to the caps. Additionally, budget deficits and the growing U.S. national debt increase pressure on the U.S. government to reduce federal spending across all federal agencies, with uncertainty about the size and timing of those reductions. Furthermore, delays in the completion of future U.S. government budgets could in the future delay procurement of the federal government services we provide. A reduction in the amount of, or delays, or cancellations of funding for, services that we are contracted to provide to the U.S. government as a result of any of these impacts or related initiatives, legislation or otherwise could have a material adverse effect on our business and results of operations.

Regulations

Increased audit, review, investigation and general scrutiny by government agencies of performance under government contracts and compliance with the terms of those contracts and applicable laws could affect our operating results. Negative publicity and increased scrutiny of government contractors in general, including us, relating to government expenditures for contractor services and incidents involving the mishandling of sensitive or classified information, as well as the increasingly complex requirements of the U.S. Department of Defense and the U.S. Intelligence Community, including those related to cybersecurity, could impact our ability to perform in the markets we serve.

Competitive Markets

The industries we operate in consist of a large number of enterprises ranging from small, niche-oriented companies to multi-billion-dollar corporations that serve many government and commercial customers. We compete on the basis of our technical expertise, technological innovation, our ability to deliver cost-effective multi-faceted services in a timely manner, our reputation and relationships with our customers, qualified and/or security-clearance personnel, and pricing. We believe that we are uniquely positioned to take advantage of the markets in which we operate because of our proven track record, long-term customer relationships, technology innovation, scalable and agile business offerings and world class talent. Our ability to effectively deliver on project engagements and successfully assist our customers affects our ability to win new contracts and drives our financial performance.

Acquired Operations

I.S. Engineers, LLC

On October 31, 2023, the Company entered into a Membership Interest Purchase Agreement to acquire a 100% ownership interest in I.S. Engineers, LLC, a privately-owned company, for $12.2 million, subject to certain adjustments. Headquartered in Texas, I.S. Engineers, LLC provides full-service consulting specializing in transportation engineering, including roads and highways, and program management. The financial results of I.S. Engineers have been included in our consolidated results of operations from October 31, 2023 onward.

Sealing Technologies, Inc.

32

On August 23, 2023, the Company acquired a 100% ownership interest in Sealing Technologies, Inc (“SealingTech”), a privately-owned company, for $179.3 million and up to an additional $25 million in the event an earn out revenue target is exceeded. Headquartered in Maryland, SealingTech expands Parsons’ customer base across the Department of Defense and Intelligence Community, and further enhances the company’s capabilities in defensive cyber operations; integrated mission-solutions powered by artificial intelligence (AI) and machine learning (ML); edge computing and edge access modernization; critical infrastructure protection; and secure data management. The financial results of SealingTech have been included in our consolidated results of operations from August 23, 2023 onward.

IPKeys Power Partners

On April 13, 2023, the Company entered into a merger agreement to acquire a 100% ownership interest in IPKeys Power Partners (“IPKeys”), a privately-owned company, for $43.0 million. The merger brings IPKeys' established customer base, expanding Parsons' presence in two rapidly growing end markets: grid modernization and cyber resiliency for critical infrastructure. Headquartered in Tinton Falls, New Jersey, IPKeys is a trusted provider of enterprise software platform solutions that is actively delivering cyber and operational security to hundreds of electric, water, and gas utilities across North America. The financial results of IPKeys have been included in our consolidated results of operations from April 13, 2023 onward.

Seasonality

Our results may be affected by variances as a result of weather conditions and contract award seasonality impacts that we experience across our businesses. The latter issue is typically driven by the U.S. federal government fiscal year-end, September 30. While not certain, it is not uncommon for U.S. government agencies to award task orders or complete other contract actions in the weeks before the end of the U.S. federal government fiscal year in order to avoid the loss of unexpended U.S. federal government fiscal year funds. In addition, we have also historically experienced higher bid and proposal costs in the months leading up to the U.S. federal government fiscal year-end as we pursue new contract opportunities expected to be awarded early in the following U.S. federal government fiscal year as a result of funding appropriated for that U.S. federal government fiscal year. Furthermore, many U.S. state governments with fiscal years ending on June 30 tend to accelerate spending during their first quarter, when new funding becomes available. We may continue to experience this seasonality in future periods, and our results of operations may be affected by it.

Results of Operations

Revenue

Our revenue consists of both services provided by our employees and pass-through fees from subcontractors and other direct costs. Our Federal Solutions segment derives revenue primarily from the U.S. federal government and our Critical Infrastructure segment derives revenue primarily from government and commercial customers.

We enter into the following types of contracts with our customers:

•Under cost-plus contracts, we are reimbursed for allowable or otherwise defined costs incurred, plus a fee. The contracts may also include incentives for various performance criteria, including quality, timeliness, safety and cost-effectiveness. In addition, costs are generally subject to review by clients and regulatory audit agencies, and such reviews could result in costs being disputed as non-reimbursable under the terms of the contract.

•Under time-and-materials contracts, hourly billing rates are negotiated and charged to clients based on the actual time spent on a project. In addition, clients reimburse actual out-of-pocket costs for other direct costs and expenses that are incurred in connection with the performance under the contract.

•Under fixed-price contracts, clients pay an agreed fixed-amount negotiated in advance for a specified scope of work.

Refer to “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Critical Accounting Policies and Estimates” and “Note 2—Summary of Significant Accounting Policies” in the notes to our consolidated financial statements included in the Company’s Form 10-K for the year ended December 31, 2023 for a description of our policies on revenue recognition.

33

The table below presents the percentage of total revenue for each type of contract.

	Three Months Ended
	March 31, 2024	March 31, 2023
Fixed-price	41.1%	29.1%
Time-and-materials	22.8%	27.1%
Cost-plus	36.1%	43.8%

The amount of risk and potential reward varies under each type of contract. Under cost-plus contracts, there is limited financial risk, because we are reimbursed for all allowable costs up to a ceiling. However, profit margins on this type of contract tend to be lower than on time-and-materials and fixed-price contracts. Under time-and-materials contracts, we are reimbursed for the hours worked using the predetermined hourly rates for each labor category. In addition, we are typically reimbursed for other direct contract costs and expenses at cost. We assume financial risk on time-and-materials contracts because our labor costs may exceed the negotiated billing rates. Profit margins on well-managed time-and-materials contracts tend to be higher than profit margins on cost-plus contracts as long as we are able to staff those contracts with people who have an appropriate skill set. Under fixed-price contracts, we are required to deliver the objectives under the contract for a pre-determined price. Compared to time-and-materials and cost-plus contracts, fixed-price contracts generally offer higher profit margin opportunities because we receive the full benefit of any cost savings, but they also generally involve greater financial risk because we bear the risk of any cost overruns. In the aggregate, the contract type mix in our revenue for any given period will affect that period’s profitability. Over time, we have generally experienced a relatively stable contract mix.

The significant change in the contract mix for the three months ended March 31, 2024 compared to the corresponding period last year relates to increased business volume from a significant fixed price contract in our Federal Solutions segment.

Our recognition of profit on long-term contracts requires the use of assumptions related to transaction price and total cost of completion. Estimates are continually evaluated as work progresses and are revised when necessary. When a change in estimated cost or transaction price is determined to have an impact on contract profit, we record a positive or negative adjustment to revenue.

Joint Ventures

We conduct a portion of our business through joint ventures or similar partnership arrangements. For the joint ventures we control, we consolidate all the revenues and expenses in our consolidated statements of income (including revenues and expenses attributable to noncontrolling interests). For the joint ventures we do not control, we recognize equity in (losses) earnings of unconsolidated joint ventures. Our revenues included amounts related to services we provided to our unconsolidated joint ventures for the three months ended March 31, 2024 and March 31, 2023 of $46.8 million and $50.9 million, respectively.

Operating costs and expenses

Operating costs and expenses primarily include direct costs of contracts and selling, general and administrative expenses. Costs associated with compensation-related expenses for our people and facilities, which includes ESOP contribution expenses, are the most significant component of our operating expenses. Total ESOP contribution expense for the three months ended March 31, 2024 and March 31, 2023 was $15.0 million and $14.4 million, respectively, and is recorded in “Direct cost of contracts” and “Selling, general and administrative expenses.”

Direct costs of contracts consist of direct labor and associated fringe benefits, indirect overhead, subcontractor and materials (“pass-through costs”), travel expenses and other expenses incurred to perform on contracts.

Selling, general and administrative expenses (“SG&A”) include salaries and wages and fringe benefits of our employees not performing work directly for customers, facility costs and other costs related to these indirect functions.

Other income and expenses

Other income and expenses primarily consist of interest income, interest expense and other income, net.

Interest income primarily consists of interest earned on U.S. government money market funds.

34

Interest expense consists of interest expense incurred under our Senior Notes, Convertible Senior Notes, and Credit Agreement.

Other income, net primarily consists of gain or loss on sale of assets, sublease income and transaction gain or loss related to movements in foreign currency exchange rates.

Adjusted EBITDA is a supplemental measure of our operating performance used by management and our board of directors to assess our financial performance both on a segment and on a consolidated basis. We discuss Adjusted EBITDA because our management uses this measure for business planning purposes, including to manage the business against internal projected results of operations and measure the performance of the business generally. Adjusted EBITDA is frequently used by analysts, investors and other interested parties to evaluate companies in our industry.

Adjusted EBITDA is not a GAAP measure of our financial performance or liquidity and should not be considered as an alternative to net income as a measure of financial performance or cash flows from operations as measures of liquidity, or any other performance measure derived in accordance with GAAP. We define Adjusted EBITDA as net income (loss) attributable to Parsons Corporation, adjusted to include net income (loss) attributable to noncontrolling interests and to exclude interest expense (net of interest income), provision for income taxes, depreciation and amortization and certain other items that we do not consider in our evaluation of ongoing operating performance. These other items include, among other things, impairment of goodwill, intangible and other assets, interest and other expenses recognized on litigation matters, expenses incurred in connection with acquisitions and other non-recurring transaction costs and expenses related to our corporate restructuring initiatives. Adjusted EBITDA should not be construed as an inference that

35

our future results will be unaffected by unusual or non-recurring items. Additionally, Adjusted EBITDA is not intended to be a measure of free cash flow for management’s discretionary use, as it does not reflect tax payments, debt service requirements, capital expenditures and certain other cash costs that may recur in the future, including, among other things, cash requirements for working capital needs and cash costs to replace assets being depreciated and amortized. Management compensates for these limitations by relying on our GAAP results in addition to using Adjusted EBITDA supplementally. Our measure of Adjusted EBITDA is not necessarily comparable to similarly titled captions of other companies due to different methods of calculation.

The following table shows Adjusted EBITDA attributable to Parsons Corporation for each of our reportable segments and Adjusted EBITDA attributable to noncontrolling interests (in thousands):

	Three Months Ended				Variance

Revenue	$	1,535,676	$	1,173,466	$	362,210		30.9	%

Revenue increased $362.2 million for the three months ended March 31, 2024 when compared to the corresponding period last year, due to increases in revenue in both our Federal Solutions and Critical Infrastructure segments of $275.1 million and $87.1 million, respectively. See “Segment Results” below for a further discussion of the changes in the Company's revenue.

Direct costs of contracts

	Three Months Ended				Variance
(U.S. dollars in thousands)	March 31, 2024		March 31, 2023		Dollar		Percent
Direct costs of contracts	$	1,210,827	$	917,188	$	293,639		32.0	%

Direct cost of contracts increased $293.6 million for the three months ended March 31, 2024 when compared to the corresponding period last year, primarily due to an increase of $227.7 million in our Federal Solutions segment and $66.0 million in our Critical Infrastructure segment. The increase in direct costs of contracts is primarily related to increased business volume from a significant contract in the Federal Solutions segment. Changes in direct cost of contracts in the Critical Infrastructure segment are primarily related to increased volume from new and existing contracts.

Equity in (losses) earnings of unconsolidated joint ventures

	Three Months Ended						Variance
(U.S. dollars in thousands)	March 31, 2024			March 31, 2023			Dollar		Percent
Equity in losses of unconsolidated joint ventures	$	(2,060	)	$	(5,840	)	$	3,780		64.7	%

Equity in (losses) earnings of unconsolidated joint ventures improved $3.8 million for the three months ended March 31, 2024 compared to the corresponding period last year. Impacting equity in losses of unconsolidated joint ventures was a write-down of $8.4 million related to Parsons' participation in a design build joint venture. This write-down was offset by improved results in certain other joint ventures compared to the corresponding period last year.

Selling, general and administrative expenses

	Three Months Ended				Variance
(U.S. dollars in thousands)	March 31, 2024		March 31, 2023		Dollar		Percent
Selling, general and administrative expenses	$	220,945	$	199,308	$	21,637		10.9	%

The increase in SG&A of $21.6 million for the three months ended March 31, 2024 when compared to the corresponding period last year was primarily due to $10.2 million increase related to employee incentive programs, a $9.0 million increase in other SG&A costs, and $5.2 million from business acquisitions. These increases were offset in part by a $4.3 million decrease in intangible asset amortization. As a percentage of revenue, our SG&A decreased by 2.6% to 14.4% for the three months ended March 31, 2024 compared to 17.0% for the corresponding period last year.

Total other income (expense)

Total other income (expense)	$	(226,190	)	$	(4,351	)	$	(221,839	)		-

During the three months ended March 31, 2024, we paid $495.6 million in cash to repurchase $284.6 million aggregate principal amount of our Convertible Senior Notes due 2025 (the "Repurchase Transaction") concurrently with the offering of 2.625% Convertible Senior Notes due 2029. As a result of the Repurchase Transaction, we incurred a $211.0 million loss on debt extinguishment. The Repurchase Transaction is a partial repurchase of our Convertible Senior Notes due 2025. See “Note 10 – Debt and Credit Facilities,” for a further discussion of this transaction.

Interest income is related to interest earned on investments in government money funds.

37

Interest expense is primarily due to debt related to our Delayed Draw Term Loan and Convertible Senior Notes. The increase in interest expense during the three months ended March 31, 2024 compared to the corresponding period last year is primarily related to an increase in debt balances, increase in interest rates, the issuance of Convertible Senior Notes due 2029, and a $3.2 million charge for the acceleration of the amortization of debt issuance costs associated with the partial repurchase of the 0.25% Convertible Senior Notes due 2025 discussed above.

The amounts in other income (expense), net are primarily related to transaction gains and losses on foreign currency transactions, sublease income and changes in the estimated fair value of contingent consideration.

Income tax (benefit) expense

	Three Months Ended					Variance
(U.S. dollars in thousands)	March 31, 2024			March 31, 2023		Dollar			Percent
Income tax (benefit) expense	$	(32,234	)	$	11,503	$	(43,737	)		-380.2	%

The Company’s effective tax rate was 25.9% and 24.6% and income tax benefit was $32.2 million and income tax expense was $11.5 million for the three months ended March 31, 2024 and March 31, 2023, respectively. The most significant items contributing to the increase in the effective tax rate relates to a change in jurisdictional mix of earnings, the foreign-derived intangible income (FDII) deduction, and equity-based compensation, partially offset by executive compensation subject to Section 162(m). The difference between the statutory U.S. federal income tax rate of 21.0% and the effective tax rate for the quarter ended March 31, 2024 primarily relates to a change in jurisdictional mix of earnings partially resulting from a loss in partially unwinding Convertible Senior Notes, the FDII deduction, equity based compensation, and untaxed income attributable to noncontrolling interests, partially offset by rate impacts related to state income taxes and foreign withholding taxes.

Segment Results

We evaluate segment operating performance using segment revenue and segment Adjusted EBITDA attributable to Parsons Corporation. Adjusted EBITDA attributable to Parsons Corporation is Adjusted EBITDA excluding Adjusted EBITDA attributable to noncontrolling interests. Presented above, in this Management’s Discussion and Analysis of Financial Condition and Results of Operations, is a discussion of our definition of Adjusted EBITDA, how we use this metric, why we present this metric and the material limitations on the usefulness of this metric. See “Note 18—Segments Information” in the notes to the consolidated financial statements in this Form 10-Q for further discussion regarding our segment Adjusted EBITDA attributable to Parsons Corporation.

The following table shows Adjusted EBITDA attributable to Parsons Corporation for each of our reportable segments and Adjusted EBITDA attributable to noncontrolling interests:

	Three Months Ended
(U.S. dollars in thousands)	March 31, 2024		March 31, 2023
Federal Solutions Adjusted EBITDA attributable to Parsons Corporation	$	92,541	$	56,148
Critical Infrastructure Adjusted EBITDA attributable to Parsons Corporation		32,963		24,357
Adjusted EBITDA attributable to noncontrolling interests		15,589		9,886
Total Adjusted EBITDA	$	141,093	$	90,391

Federal Solutions

	Three Months Ended				Variance
(U.S. dollars in thousands)	March 31, 2024		March 31, 2023		Dollar		Percent
Revenue	$	909,608	$	634,546	$	275,062		43.3	%
Adjusted EBITDA attributable to Parsons Corporation	$	92,541	$	56,148	$	36,393		64.8	%

The increase in Federal Solutions revenue for the three months ended March 31, 2024 compared to the corresponding period last year was primarily related to organic growth of 41% and $16.9 million from business acquisitions. Organic growth was due to the ramp up of new awards on a significant contract along with the ramp up of

38

other new awards. Partially offsetting these increases is the timing of task order awards for additional follow-on phases of work on certain existing contracts.

The increase in Federal Solutions Adjusted EBITDA attributable to Parsons Corporation for the three months ended March 31, 2024 compared to the corresponding period last year was primarily due to organic growth described above.

Critical Infrastructure

	Three Months Ended				Variance
(U.S. dollars in thousands)	March 31, 2024		March 31, 2023		Dollar		Percent
Revenue	$	626,068	$	538,920	$	87,148		16.2	%
Adjusted EBITDA attributable to Parsons Corporation	$	32,963	$	24,357	$	8,606		35.3	%

The increase in Critical Infrastructure revenue for the three months ended March 31, 2024 compared to the corresponding periods last year was primarily related to organic growth of 15% and $6.2 million from business acquisitions. Organic growth was primarily due to an increase in business volume from existing contracts and ramping up of recent awards.

The increase in Critical Infrastructure Adjusted EBITDA attributable to Parsons Corporation for the three months ended March 31, 2024 compared to the corresponding period last year was primarily due to the revenue impacts discussed above and improvement in equity in losses from unconsolidated joint ventures.

Liquidity and Capital Resources

We currently finance our operations and capital expenditures through a combination of internally generated cash from operations, our Convertible Senior Notes, Delayed Draw Term Loan and periodic borrowings under our Revolving Credit Facility.

Generally, cash provided by operating activities has been adequate to fund our operations. Due to fluctuations in our cash flows and growth in our operations, it may be necessary from time to time in the future to borrow under our Credit Agreement to meet cash demands. Our management regularly monitors certain liquidity measures to monitor performance. We calculate our available liquidity as a sum of cash and cash equivalents from our consolidated balance sheet plus the amount available and unutilized on our Credit Agreement.

As of March 31, 2024, we believe we have adequate liquidity and capital resources to fund our operations, support our debt service and our ongoing acquisition strategy for at least the next twelve months based on the liquidity from cash provided by our operating activities, cash and cash equivalents on-hand and our borrowing capacity under our Revolving Credit Facility. Management continually monitors debt maturities to strategically execute optimal terms and ensure appropriate levels of working capital liquidity are maintained for the company.

Cash Flows

Cash received from customers, either from the payment of invoices for work performed or for advances in excess of revenue recognized, is our primary source of cash. We generally do not begin work on contracts until funding is appropriated by the customers. Billing timetables and payment terms on our contracts vary based on a number of factors, including whether the contract type is cost-plus, time-and-materials, or fixed-price. We generally bill and collect cash more frequently under cost-plus and time-and-materials contracts, as we are authorized to bill as the costs are incurred or work is performed. In contrast, we may be limited to bill certain fixed-price contracts only when specified milestones, including deliveries, are achieved. A number of our contracts may provide for performance-based payments, which allow us to bill and collect cash prior to completing the work.

Billed accounts receivable represents amounts billed to clients that have not been collected. Unbilled accounts receivable represents amounts where the Company has a present contractual right to bill but an invoice has not been issued to the customer at the period-end date.

Accounts receivable is the principal component of our working capital and includes billed and unbilled amounts. The total amount of our accounts receivable can vary significantly over time but is generally sensitive to revenue levels. We experience delays in collections from time to time from Middle East customers. Net days sales outstanding, which we refer to as Net DSO, is calculated by dividing (i) (accounts receivable plus contract assets) less (contract liabilities plus

39

accounts payable) by (ii) average revenue per day (calculated by dividing trailing twelve months revenue by the number of days in that period). We focus on collecting outstanding receivables to reduce Net DSO and working capital. Net DSO was 63 days at March 31, 2024 down from 69 days at March 31, 2023. Our working capital (current assets less current liabilities) was $1.1 billion at March 31, 2024 and $726.6 million at December 31, 2023.

Our cash and cash equivalents increased by $150.2 million to $423.1 million at March 31, 2024 from $272.9 million at December 31, 2023.

The following table summarizes our sources and uses of cash over the periods presented (in thousands):

	Three Months Ended
	March 31, 2024			March 31, 2023
Net cash used in operating activities	$	(63,420	)	$	(8,990	)
Net cash used in investing activities		(45,510	)		(20,762	)
Net cash provided by (used in) financing activities		259,509			(12,502	)
Effect of exchange rate changes		(402	)		154
Net increase (decrease) in cash and cash equivalents	$	150,177		$	(42,100	)

Operating Activities

Net cash used in operating activities consists primarily of net income adjusted for noncash items, such as: equity in losses (earnings) of unconsolidated joint ventures, contributions of treasury stock, depreciation and amortization of property and equipment and intangible assets, and provisions for doubtful accounts. The timing between the conversion of our billed and unbilled receivables into cash from our customers and disbursements to our employees and vendors is the primary driver of changes in our working capital. Our operating cash flows are primarily affected by our ability to invoice and collect from our clients in a timely manner, our ability to manage our vendor payments and the overall profitability of our contracts.

Net cash used in operating activities increased $54.4 million for the three months ended March 31, 2024 compared to the three months ended March 31, 2023. The primary driver of the increase in cash flows used in operating activities was an $152.6 million increase in cash outflows from our working capital accounts (primarily from accounts receivable, accrued expenses and other current liabilities, contract liabilities, and income taxes partially offset by contract assets and accounts payable) this increase in cash flows used in operating activities was offset, in part by $102.1 million in net income after adjusting for non-cash items and debt extinguishment.

Investing Activities

Net cash used in investing activities consists primarily of cash flows associated with capital expenditures, joint ventures and business acquisitions.

Net cash used in investing activities increased $24.7 million for the three months ended March 31, 2024, when compared to the three months ended March 31, 2023. This change was primarily driven by a $23.1 million increase in investments in unconsolidated joint ventures.

Financing Activities

Net cash provided by financing activities is primarily associated with proceeds from debt, the repayment thereof, and distributions to noncontrolling interests.

Net cash used in financing activities increased $272.0 million for the three months ended March 31, 2024 compared to the three months ended March 31, 2023. The change in cash flows from financing activities is primarily driven by net cash inflows from our convertible bond transactions which generated $287.7 million in cash. See “Note 10 – Debt and Credit Facilities,” for a further discussion of these transactions.

Letters of Credit

We have in place several secondary bank credit lines for issuing letters of credit, principally for foreign contracts, to support performance and completion guarantees. Letters of credit commitments outstanding under these bank lines aggregated to $281.1 million as of March 31, 2024. Letters of credit outstanding under the Credit Agreement total $42.1 million as of March 31, 2024.

Recent Accounting Pronouncements

See the information set forth in “Note 3—New Accounting Pronouncements” in the notes to our consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q.

Off-Balance Sheet Arrangements

As of March 31, 2024, we have no off-balance sheet arrangements that have or are reasonably likely to have a material current or future effect on our financial condition, changes in financial condition, revenue or expenses, results of operations, liquidity, capital expenditures or capital resources.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

Interest Rate Risk

We are exposed to interest rate risks related to the Company’s Revolving Credit Facility and Delayed Draw
Term Loan.

As of March 31, 2024, there were no amounts outstanding under the Revolving Credit Facility. Borrowings under the new Credit Facility effective June 2021 bear interest at either the Term SOFR rate plus a margin between 1.0% and 1.625%, or a base rate (as defined in the Credit Agreement) plus a margin of between 0% and 0.625%, both based on the leverage ratio of the Company at the end of each quarter. The rates on March 31, 2024 and December 31, 2023 were 6.6% and 6.7%, respectively.

As of March 31, 2024, there was $350.0 million outstanding under the Delayed Draw Term Loan.
Borrowings under the 2022 Delayed Draw Term Loan Agreement will bear interest at either an adjusted Term
SOFR benchmark rate plus a margin between 0.875% and 1.500% or a base rate plus a margin of between 0%
and 0.500% and will initially bear interest at the middle of this range. The Company will pay a ticking fee on
unused term loan commitments at a rate of 0.175% commencing with the date that is ninety (90) days after the
Closing Date. The interest rate at March 31, 2024 and December 31, 2023 were 6.4% and 6.6%, respectively.

Foreign Currency Exchange Risk

We are exposed to foreign currency exchange rate risk resulting from our operations outside of the U.S. We limit exposure to foreign currency fluctuations in most of our contracts through provisions that require client payments in currencies corresponding to the currency in which costs are incurred. As a result of this natural hedge, we generally do not need to hedge foreign currency cash flows for contract work performed.

Item 4. Controls and Procedures.

Evaluation of Disclosure Control and Procedures

Our management carried out, as of March 31, 2024, with the participation of our Chief Executive Officer and our Chief Financial Officer, an evaluation of the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)). Based on that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that, as of March 31, 2024, our disclosure controls and procedures were effective to provide reasonable assurance that material information required to be disclosed by us in reports we file under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC rules and forms and that information required to be disclosed by us in the reports we file or submit under the Exchange Act is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

Changes in Internal Control Over Financial Reporting

During the first quarter of 2024, there were no changes to our internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Item 1A. Risk Factors.

There have been no material changes to our Risk Factors disclosed in the Company’s Form 10-K for the year ended December 31, 2023.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds.

Issuer Purchases of Equity Securities

On August 9, 2021, the Company’s Board of Directors authorized the Company to acquire a number of shares of Common Stock having an aggregate market value of not greater than $100 million from time to time, commencing on August 12, 2021. The Board further amended this authorization in August 2022 to remove the prior expiration date and grant executive leadership the discretion to determine the price for such share repurchases. The Board further amended this authorization in February 2024 to restore the repurchase capacity to $100 million and removed the $25 million quarterly cap on such repurchases.

At the time of the February 2024 authorization, the Company had repurchased shares with an aggregated market value (including fees) of $54.7 million. As of March 31, 2024, the Company has $100 million remaining under the stock repurchase program. The aggregate market value of shares of Common Stock the Company is authorized to acquire is now not greater than $154.7 million.

Repurchased shares of common stock are retired and included in “Repurchases of common stock” in cash flows from financing activities in the Consolidated Statements of Cash Flows. The primary purpose of the Company’s share repurchase program is to reduce the dilutive effect of shares issued under the Company’s ESOP and other stock benefit plans. The timing, amount and manner of share repurchases may depend upon market conditions and economic circumstances, availability of investment opportunities, the availability and costs of financing, the market price of the Company's common stock, other uses of capital and other factors.

As of March 31, 2024, the Company has spent $54.7 million (which includes commissions paid of $29 thousand)
repurchasing 1,426,476 shares of Common Stock (all of which have been retired) at an average price of $38.35 per share.

There were no share repurchases during the three months ended March 31, 2024.

(c) Any Defaulted Amounts shall forthwith cease to be payable to the Holder on the relevant payment date but shall accrue interest per annum at the rate borne by the Notes, subject to the enforceability thereof under applicable law, from, and including, such relevant payment date, and such Defaulted Amounts together with such interest thereon shall be paid by the Company, at its election in each case, as provided in clause (i) or (ii) below:

16

Exhibit 4.1

(i) The Company may elect to make payment of any Defaulted Amounts to the Persons in whose names the Notes (or their respective Predecessor Notes) are registered at the close of business on a special record date for the payment of such Defaulted Amounts, which shall be fixed in the manner set forth in the remainder of this Section 2.03(c)(i). The Company shall notify the Trustee in writing of the amount of the Defaulted Amounts proposed to be paid on each Note and the date of the proposed payment (which shall be not less than 25 days after the receipt by the Trustee of such notice, unless the Trustee shall consent to an earlier date), and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount to be paid in respect of such Defaulted Amounts or shall make arrangements satisfactory to the Trustee for such deposit on or prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Amounts pursuant to this Section 2.03(c)(i).

Such certificate by the Trustee (or such an authenticating agent) upon any Note executed by the Company shall be conclusive evidence that the Note so authenticated has been duly authenticated and delivered hereunder and that the Holder is entitled to the benefits of this Indenture.

In case any Officer of the Company who shall have signed any of the Notes shall cease to be such Officer before the Notes so signed shall have been authenticated and delivered by the Trustee, or disposed of by the Company, such Notes nevertheless may be authenticated and delivered or disposed of as though the person who signed such Notes had not ceased to be such Officer of the Company; and any Note may be signed on behalf of the Company by such persons as, at the actual date of the execution of such Note, shall be the Officers of the Company, although at the date of the execution of this Indenture any such person was not such an Officer.

Section 2.05. Exchange and Registration of Transfer of Notes; Restrictions on Transfer; Depositary. (a) The Company shall cause to be kept at the Corporate Trust Office a register (the register maintained in such office or in any other office or agency of the Company designated pursuant to Section 4.02, the “Note Register”) in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of Notes and of transfers of Notes. Such register shall be in written form or in any form capable of being converted into written form within a reasonable period of time.

No service charge shall be imposed by the Company, the Trustee, the Note Registrar, any co-Note Registrar or the Paying Agent for any exchange or registration of transfer of Notes, but the Company may require a Holder to pay a sum sufficient to cover any documentary, stamp or similar issue or transfer tax required in connection therewith as a result of the name of the Holder of new Notes issued upon such exchange or registration of transfer being different from the name of the Holder of the old Notes surrendered for exchange or registration of transfer.

None of the Company, the Trustee, the Note Registrar or any co-Note Registrar shall be required to exchange or register a transfer of (i) any Notes surrendered for conversion or, if a portion of any Note is surrendered for conversion, such portion thereof surrendered for conversion, (ii) any Notes, or a portion of any Note, surrendered for repurchase (and not withdrawn) in accordance with Article 15 or (iii) any Notes selected for redemption in accordance with Article 16, except the unredeemed portion of any Note being redeemed in part.

All Notes issued upon any registration of transfer or exchange of Notes in accordance with this Indenture shall be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Indenture as the Notes surrendered upon such registration of transfer or exchange.

The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Note other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by the terms of, this Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof.

(b) So long as the Notes are eligible for book-entry settlement with the Depositary, unless otherwise required by law, subject to the fourth paragraph from the end of Section 2.05(c) all Notes shall be represented by one or more Notes in global form (each, a “Global Note”) registered in the name of the Depositary or the nominee of the Depositary. The transfer and exchange of beneficial interests in a Global Note that does not involve the issuance of a Physical Note shall be effected through the Depositary (but not the Trustee or the Custodian) in accordance with this Indenture (including the restrictions on transfer set forth herein) and the procedures of the Depositary therefor.

As used in this Section 2.05(c) and Section 2.05(d), the term “transfer” encompasses any sale, pledge, transfer or other disposition whatsoever of any Restricted Security (or any voting or economic rights thereto or any beneficial interest therein).

Until the date (the “Resale Restriction Termination Date”) that is the later of (1) the date that is one year after the Last Original Issue Date of the Notes, or such shorter period of time as permitted by Rule 144 or any successor provision thereto, and (2) such later date, if any, as may be required by applicable law, any certificate evidencing such Note (and all securities issued in exchange therefor or substitution thereof, other than Common Stock, if any, issued upon conversion thereof, which shall bear the legend set forth in Section 2.05(d), if applicable) shall bear a legend in substantially the following form (unless such Notes have been transferred pursuant to a registration statement that has become or been declared effective under the Securities Act and that continues to be effective at the time of such transfer, or sold pursuant to the exemption from registration provided by Rule 144 or any similar provision then in force under the Securities Act, or unless otherwise agreed by the Company in writing, with written notice thereof to the Trustee):

20

Exhibit 4.1

(B) PURSUANT TO A REGISTRATION STATEMENT THAT HAS BECOME EFFECTIVE UNDER THE SECURITIES ACT, OR

(C) TO A PERSON REASONABLY BELIEVED TO BE A QUALIFIED INSTITUTIONAL BUYER IN COMPLIANCE WITH RULE 144A UNDER THE SECURITIES ACT, OR

(D) PURSUANT TO AN EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 UNDER THE SECURITIES ACT OR ANY OTHER AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT.

PRIOR TO THE REGISTRATION OF ANY TRANSFER IN ACCORDANCE WITH CLAUSE (2)(D) ABOVE, THE COMPANY AND THE TRUSTEE RESERVE THE RIGHT TO REQUIRE THE DELIVERY OF SUCH LEGAL OPINIONS, CERTIFICATIONS OR OTHER EVIDENCE AS MAY REASONABLY BE REQUIRED IN ORDER FOR THE COMPANY TO DETERMINE THAT THE PROPOSED TRANSFER IS BEING MADE IN COMPLIANCE WITH THE SECURITIES ACT AND APPLICABLE STATE SECURITIES LAWS. NO REPRESENTATION IS MADE AS TO THE AVAILABILITY OF ANY EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT.

No transfer of any Note prior to the Resale Restriction Termination Date will be registered by the Note Registrar unless the applicable box on the Form of Assignment and Transfer has been checked.

Any Note (or security issued in exchange or substitution therefor) (i) as to which such restrictions on transfer shall have expired in accordance with their terms, (ii) that has been transferred pursuant to a registration statement that has become effective or been declared effective under the Securities Act and that continues to be effective at the time of such transfer or (iii) that has been sold pursuant to the exemption from registration provided by Rule 144 or any similar provision then in force under the Securities Act, may, upon surrender of such Note for exchange to the Note Registrar in accordance with the provisions of this Section 2.05, be exchanged for a new Note or Notes, of like tenor and aggregate principal amount, which shall not bear the restrictive legend required by this Section 2.05(c) and shall not be assigned a restricted CUSIP number. The Company shall be entitled to instruct the Custodian in writing to so surrender any Global Note as to which any of the conditions set forth in clause (i) through (iii) of the immediately preceding sentence have been satisfied, and, upon such instruction, the Custodian shall so surrender such Global Note for exchange; and any new Global Note so exchanged therefor shall not bear the restrictive legend specified in this Section 2.05(c) and shall not be assigned a restricted CUSIP number.

Without limiting the generality of any other provision of this Indenture, the restrictive legend required by this Section 2.05(c) affixed to any Note will be deemed, pursuant to this Section 2.05(c) and the footnote to such legend in such Note, to be removed therefrom upon the Company’s delivery to the Trustee of notice, signed on behalf of the Company by one (1) of its

21

Exhibit 4.1

Officers, to such effect (and, for the avoidance of doubt, such notice need not be accompanied by an Officer’s Certificate or an Opinion of Counsel in order to be effective to cause such legend to be deemed to be removed from such Note). If such Note bears a “restricted” CUSIP or ISIN number at the time of such delivery, then, upon such delivery, such Note will be deemed, pursuant to this Section 2.05(c) and the footnotes to the CUSIP and ISIN numbers set forth on the face of the certificate representing such Note, to thereafter bear the “unrestricted” CUSIP and ISIN numbers identified in such footnotes; provided, however, that if such Note is a Global Note and the Depositary thereof requires a mandatory exchange or other procedure to cause such Global Note to be identified by “unrestricted” CUSIP and ISIN numbers in the facilities of such Depositary, then (i) the Company will effect such exchange or procedure as soon as reasonably practicable; and (ii) for purposes of Section 4.06, such Global Note will not be deemed to be identified by unrestricted CUSIP and ISIN numbers until such time as such exchange or procedure is effected.

Notwithstanding any other provisions of this Indenture (other than the provisions set forth in this Section 2.05(c)), a Global Note may not be transferred as a whole or in part except (i) by the Depositary to a nominee of the Depositary or by a nominee of the Depositary to the Depositary or another nominee of the Depositary or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary and (ii) for exchange of a Global Note or a portion thereof for one or more Physical Notes in accordance with the second immediately succeeding paragraph.

The Depositary shall be a clearing agency registered under the Exchange Act. The Company initially appoints The Depository Trust Company to act as Depositary with respect to each Global Note. Initially, each Global Note shall be issued to the Depositary, registered in the name of Cede & Co., as the nominee of the Depositary, and deposited with the Trustee as custodian for Cede & Co.

If (i) the Depositary notifies the Company at any time that the Depositary is unwilling or unable to continue as depositary for the Global Notes and a successor depositary is not appointed within 90 days, (ii) the Depositary ceases to be registered as a clearing agency under the Exchange Act and a successor depositary is not appointed within 90 days or (iii) an Event of Default with respect to the Notes has occurred and is continuing and a beneficial owner of any Note requests that its beneficial interest therein be issued as a Physical Note, the Company shall execute, and the Trustee, upon receipt of an Officer’s Certificate, an Opinion of Counsel and a Company Order for the authentication and delivery of Notes, shall authenticate and deliver (x) in the case of clause (iii), a Physical Note to such beneficial owner in a principal amount equal to the principal amount of such Note corresponding to such beneficial owner’s beneficial interest and (y) in the case of clause (i) or (ii), Physical Notes to each beneficial owner of the related Global Notes (or a portion thereof) in an aggregate principal amount equal to the aggregate principal amount of such Global Notes in exchange for such Global Notes, and upon delivery of the interests in the Global Notes to the Trustee such interests in the Global Notes shall be canceled.

22

Exhibit 4.1

Physical Notes issued in exchange for all or a part of the Global Note pursuant to this Section 2.05(c) shall be registered in such names and in such Authorized Denominations as the Depositary, pursuant to instructions from its direct or indirect participants or otherwise, or, in the case of clause (iii) of the immediately preceding paragraph, the relevant beneficial owner, shall instruct the Trustee. Upon execution and authentication, the Trustee shall deliver such Physical Notes to the Persons in whose names such Physical Notes are so registered.

At such time as all interests in a Global Note have been converted, canceled, repurchased, redeemed or transferred, such Global Note shall be, upon receipt thereof, canceled by the Trustee in accordance with standing procedures and existing instructions between the Depositary and the Custodian. At any time prior to such cancellation, if any interest in a Global Note is exchanged for Physical Notes, converted, canceled, repurchased, redeemed or transferred to a transferee who receives Physical Notes therefor or any Physical Note is exchanged or transferred for part of such Global Note, the principal amount of such Global Note shall, in accordance with the standing procedures and instructions existing between the Depositary and the Custodian, be appropriately reduced or increased, as the case may be, and an endorsement shall be made on such Global Note, by the Trustee or the Custodian, at the direction of the Trustee, to reflect such reduction or increase.

None of the Company, the Trustee (including in its capacity as Paying Agent) or any agent of the Company or the Trustee shall have any responsibility or liability for the payment of amounts to owners of a beneficial interest in a Global Note, for any aspect of the records relating to or payments made on account of beneficial ownership interests of a Global Note or maintaining, supervising or reviewing any records relating to such beneficial ownership interests.

Neither the Company nor the Trustee shall have any responsibility or liability for any act or omission of the Depositary. All notices and communications to be given to the Holders and all payments to be made to Holders in respect of the Notes shall be given or made only to, or upon the order of, the registered Holder(s) (which shall be the Depositary or its nominee in the case of a Global Note).

The rights of beneficial owners in any Global Note shall be exercised only through the Depositary subject to the applicable procedures of the Depositary. The Trustee may rely and shall be fully protected in relying upon information furnished by the Depositary with respect to its members, participants and any beneficial owners.

(d) Until the Resale Restriction Termination Date, any stock certificate representing Common Stock issued upon conversion of a Note shall bear a legend in substantially the following form (unless such Common Stock has been transferred pursuant to a registration statement that has become or been declared effective under the Securities Act and that continues to be effective at the time of such transfer, or pursuant to the exemption from registration provided by Rule 144 or any similar provision then in force under the Securities Act, or such Common Stock has been issued upon conversion of a Note that has been transferred pursuant to a registration statement that has become or been declared effective under the Securities Act and that continues to be effective at the time of such transfer, or pursuant to the exemption from

23

Exhibit 4.1

registration provided by Rule 144 or any similar provision then in force under the Securities Act, or unless otherwise agreed by the Company with written notice thereof to the Trustee and any transfer agent for the Common Stock):

THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND MAY NOT BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED EXCEPT IN ACCORDANCE WITH THE FOLLOWING SENTENCE. BY ITS ACQUISITION HEREOF OR OF A BENEFICIAL INTEREST HEREIN, THE ACQUIRER:

(1) REPRESENTS THAT IT AND ANY ACCOUNT FOR WHICH IT IS ACTING IS A “QUALIFIED INSTITUTIONAL BUYER” (WITHIN THE MEANING OF RULE 144A UNDER THE SECURITIES ACT) AND THAT IT EXERCISES SOLE INVESTMENT DISCRETION WITH RESPECT TO EACH SUCH ACCOUNT, AND

(2) AGREES FOR THE BENEFIT OF PARSONS CORPORATION (THE “COMPANY”) THAT IT WILL NOT OFFER, SELL, PLEDGE OR OTHERWISE TRANSFER THIS SECURITY OR ANY BENEFICIAL INTEREST HEREIN PRIOR TO THE DATE THAT IS THE LATER OF (X) ONE YEAR AFTER THE LAST ORIGINAL ISSUE DATE OF THE SERIES OF NOTES UPON THE CONVERSION OF WHICH THIS SECURITY WAS ISSUED OR SUCH SHORTER PERIOD OF TIME AS PERMITTED BY RULE 144 UNDER THE SECURITIES ACT OR ANY SUCCESSOR PROVISION THERETO AND (Y) SUCH LATER DATE, IF ANY, AS MAY BE REQUIRED BY APPLICABLE LAW, EXCEPT:

(A) TO THE COMPANY OR ANY SUBSIDIARY THEREOF, OR

(B) PURSUANT TO A REGISTRATION STATEMENT THAT HAS BECOME EFFECTIVE UNDER THE SECURITIES ACT, OR

(C) TO A PERSON REASONABLY BELIEVED TO BE A QUALIFIED INSTITUTIONAL BUYER IN COMPLIANCE WITH RULE 144A UNDER THE SECURITIES ACT, OR

(D) PURSUANT TO AN EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 UNDER THE SECURITIES ACT OR ANY OTHER AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT.

PRIOR TO THE REGISTRATION OF ANY TRANSFER IN ACCORDANCE WITH CLAUSE (2)(D) ABOVE, THE COMPANY AND THE TRANSFER AGENT FOR THE COMPANY’S COMMON STOCK RESERVE THE RIGHT TO REQUIRE THE DELIVERY OF SUCH LEGAL OPINIONS, CERTIFICATIONS OR OTHER EVIDENCE AS MAY REASONABLY BE REQUIRED IN ORDER FOR THE COMPANY TO DETERMINE THAT THE PROPOSED TRANSFER IS BEING MADE IN COMPLIANCE WITH THE SECURITIES ACT AND APPLICABLE STATE SECURITIES LAWS. NO

24

Exhibit 4.1

REPRESENTATION IS MADE AS TO THE AVAILABILITY OF ANY EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT.

Any such Common Stock (i) as to which such restrictions on transfer shall have expired in accordance with their terms, (ii) that has been transferred pursuant to a registration statement that has become or been declared effective under the Securities Act and that continues to be effective at the time of such transfer or (iii) that has been sold pursuant to the exemption from registration provided by Rule 144 or any similar provision then in force under the Securities Act, may, upon surrender of the certificates representing such shares of Common Stock for exchange in accordance with the procedures of the transfer agent for the Common Stock, be exchanged for a new certificate or certificates for a like aggregate number of shares of Common Stock, which shall not bear the restrictive legend required by this Section 2.05(d).

(e) Any Note or Common Stock issued upon the conversion or exchange of a Note that is repurchased or owned by any Affiliate of the Company (or any Person who was an Affiliate of the Company at any time during the three months immediately preceding) may not be resold by such Affiliate (or such Person, as the case may be) unless registered under the Securities Act or resold pursuant to an exemption from the registration requirements of the Securities Act in a transaction that results in such Note or Common Stock, as the case may be, no longer being a “restricted security” (as defined under Rule 144).

(f) Notwithstanding anything contained herein to the contrary, neither the Trustee nor the Note Registrar shall be responsible for ascertaining whether any transfer complies with the registration provisions of, or exemptions from, the Securities Act, applicable state securities laws or other applicable law.

(g) Neither the Trustee nor any agent shall have any responsibility or liability for any actions taken or not taken by the Depositary, and may assume performance absent written notice to the contrary.

Section 2.06. Mutilated, Destroyed, Lost or Stolen Notes. In case any Note shall become mutilated or be destroyed, lost or stolen, the Company in its discretion may execute, and upon receipt of a Company Order, the Trustee or an authenticating agent appointed by the Trustee shall authenticate and deliver, a new Note, bearing a registration number not contemporaneously outstanding, in exchange and substitution for the mutilated Note, or in lieu of and in substitution for the Note so destroyed, lost or stolen. In every case the applicant for a substituted Note shall furnish to the Company, to the Trustee and, if applicable, to such authenticating agent such security or indemnity as may be required by them to save each of them harmless from any loss, liability, cost or expense caused by or connected with such substitution, and, in every case of destruction, loss or theft, the applicant shall also furnish to the Company, to the Trustee and, if applicable, to such authenticating agent evidence to their satisfaction of the destruction, loss or theft of such Note and of the ownership thereof.

The Trustee or such authenticating agent may authenticate any such substituted Note and deliver the same upon the receipt of such security or indemnity as the Trustee, the Company and,

25

Exhibit 4.1

if applicable, such authenticating agent may require. No service charge shall be imposed by the Company, the Trustee, the Note Registrar, any co-Note Registrar or the Paying Agent upon the issuance of any substitute Note, but the Company may require a Holder to pay a sum sufficient to cover any documentary, stamp or similar issue or transfer tax required in connection therewith as a result of the name of the Holder of the new substitute Note being different from the name of the Holder of the old Note that became mutilated or was destroyed, lost or stolen. In case any Note that has matured or is about to mature or has been surrendered for required repurchase or is about to be converted in accordance with Article 14 shall become mutilated or be destroyed, lost or stolen, the Company may, in its sole discretion, instead of issuing a substitute Note, pay or authorize the payment of or convert or authorize the conversion of the same (without surrender thereof except in the case of a mutilated Note), as the case may be, if the applicant for such payment or conversion shall furnish to the Company, to the Trustee and, if applicable, to such authenticating agent such security or indemnity as may be required by them to save each of them harmless for any loss, liability, cost or expense caused by or connected with such substitution, and, in every case of destruction, loss or theft, evidence satisfactory to the Company, the Trustee and, if applicable, any Paying Agent or Conversion Agent evidence of their satisfaction of the destruction, loss or theft of such Note and of the ownership thereof.

Every substitute Note issued pursuant to the provisions of this Section 2.06 by virtue of the fact that any Note is destroyed, lost or stolen shall constitute an additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Note shall be found at any time, and shall be entitled to all the benefits of (but shall be subject to all the limitations set forth in) this Indenture equally and proportionately with any and all other Notes duly issued hereunder. To the extent permitted by law, all Notes shall be held and owned upon the express condition that the foregoing provisions are exclusive with respect to the replacement, payment, redemption, conversion or repurchase of mutilated, destroyed, lost or stolen Notes and shall preclude any and all other rights or remedies notwithstanding any law or statute existing or hereafter enacted to the contrary with respect to the replacement, payment, redemption, conversion or repurchase of negotiable instruments or other securities without their surrender.

Section 2.07. Temporary Notes. Pending the preparation of Physical Notes, the Company may execute and the Trustee or an authenticating agent appointed by the Trustee shall, upon receipt of a Company Order, authenticate and deliver temporary Notes (printed or lithographed). Temporary Notes shall be issuable in any Authorized Denomination, and substantially in the form of the Physical Notes but with such omissions, insertions and variations as may be appropriate for temporary Notes, all as may be determined by the Company. Every such temporary Note shall be executed by the Company and authenticated by the Trustee or such authenticating agent upon the same conditions and in substantially the same manner, and with the same effect, as the Physical Notes. Without unreasonable delay, the Company shall execute and deliver to the Trustee or such authenticating agent Physical Notes (other than any Global Note) and thereupon any or all temporary Notes (other than any Global Note) may be surrendered in exchange therefor, at each office or agency maintained by the Company pursuant to Section 4.02 and the Trustee or such authenticating agent shall authenticate and deliver in exchange for such temporary Notes an equal aggregate principal amount of Physical Notes. Such exchange shall be made by the Company at its own expense and without any charge

26

Exhibit 4.1

therefor. Until so exchanged, the temporary Notes shall in all respects be entitled to the same benefits and subject to the same limitations under this Indenture as Physical Notes authenticated and delivered hereunder.

Section 2.08. Cancellation of Notes Paid, Converted, Etc. The Company shall cause all Notes surrendered for the purpose of payment at maturity, repurchase upon a Fundamental Change, redemption, registration of transfer or exchange (other than a transfer or exchange to, or for the benefit of, the Company or its Subsidiaries or other Affiliates) or conversion, if surrendered to the Company or any of the Company’s agents, Subsidiaries or Affiliates that the Company controls, to be surrendered to the Trustee for cancellation. Concurrently with surrendering such Notes to the Trustee, the Company shall deliver a cancellation order to the Trustee. All Notes delivered to the Trustee for cancellation in accordance with this Section 2.08 shall be canceled promptly by it in accordance with its customary procedures. Except as expressly permitted by any of the provisions of this Indenture, no Notes shall be authenticated in exchange for any Notes surrendered to the Trustee for cancellation. The Trustee shall dispose of canceled Notes in accordance with its customary procedures and, after such disposition, shall deliver a certificate of such disposition to the Company, at the Company’s written request in a Company Order.

Section 2.09. CUSIP Numbers. The Company in issuing the Notes may use CUSIP numbers (if then generally in use), and, if so, the Company and/or the Trustee shall use CUSIP numbers in all notices issued to Holders as a convenience to such Holders; provided that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Notes or on such notice and that reliance may be placed only on the other identification numbers printed on the Notes. The Company shall promptly notify the Trustee in writing of any change in the CUSIP numbers.

Section 2.10. Additional Notes; Repurchases. The Company may, without the consent of the Holders and notwithstanding Section 2.01, reopen this Indenture and issue additional Notes hereunder with the same terms as the Notes initially issued hereunder (other than differences in the issue date, the issue price and interest accrued prior to the issue date of such additional Notes) in an unlimited aggregate principal amount; provided that if any such additional Notes are not fungible with the Notes initially issued hereunder for U.S. federal income tax or securities law purposes, such additional Notes shall have a separate CUSIP number. For the avoidance of doubt, notwithstanding any other provision of this Indenture to the contrary, for purposes of Section 4.06(d) and Section 4.06(e), in the event additional Notes are issued pursuant to this Section 2.10, references to the “Last Original Issue Date” of the Notes with respect to such additional Notes shall refer only to such additional Notes. Prior to the issuance of any such additional Notes, the Company shall deliver to the Trustee a Company Order, an Officer’s Certificate and an Opinion of Counsel which such Opinion of Counsel shall state that such Notes, when authenticated and delivered by the Trustee and issued by the Company in the manner and subject to any conditions specified in such Opinion of Counsel, will constitute valid and legally binding obligations of the Company, enforceable in accordance with their terms, subject to bankruptcy, insolvency, reorganization and other laws of general

27

Exhibit 4.1

applicability relating to or affecting the enforcement of creditors’ rights and to general equity principles.

In addition, the Company may, to the extent permitted by law, and directly or indirectly (regardless of whether such Notes are surrendered to the Company), repurchase Notes in the open market or otherwise, whether by the Company or its Subsidiaries or through a private or public tender or exchange offer or through counterparties to private agreements, including by cash-settled swaps or other cash-settled derivatives, in each case, without prior notice to the Holders. The Company may, at its option, and to the extent permitted by applicable law, reissue, resell or surrender to the Trustee for cancellation any Notes that the Company may repurchase; provided that if any such reissued or resold Notes are not fungible with the Notes initially issued to this Indenture for U.S. federal income tax or securities law purposes, such reissued or resold Notes shall have one or more separate CUSIP numbers. Any Notes that the Company or its Subsidiaries have purchased or otherwise acquired (other than Notes surrendered for cancellation pursuant to Section 2.08) shall be deemed to remain outstanding until such time as the Company delivers such Notes to the Trustee for cancellation in accordance with Section 2.08; provided, however, subject to the terms of this Indenture, Notes that the Company or any of its Affiliates own shall be deemed not to be outstanding for purposes of determining whether the Holders have concurred in any direction, waiver, consent or other action under this Indenture.

Article 3
Satisfaction and Discharge

Section 3.01. Satisfaction and Discharge. This Indenture shall upon request of the Company contained in an Officer’s Certificate cease to be of further effect, and the Trustee, at the expense of the Company, shall execute such instruments reasonably requested by the Company acknowledging satisfaction and discharge of this Indenture, when (a) (i) all Notes theretofore authenticated and delivered (other than Notes which have been destroyed, lost or stolen and which have been replaced, paid or converted as provided in Section 2.06) have been delivered to the Trustee for cancellation; or (ii) the Company has deposited with the Trustee or, in the case of shares of Common Stock, the Company has delivered to Holders, as applicable, after the Notes have become due and payable, whether on the Maturity Date, any Redemption Date, any Fundamental Change Repurchase Date, upon conversion or otherwise, cash (or cash and, if applicable, shares of Common Stock (or other Reference Property), solely to satisfy the Company’s Conversion Obligation) sufficient to pay all of the outstanding Notes and all other sums due and payable under this Indenture by the Company; and (b) the Company has delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that all conditions precedent herein provided for relating to the satisfaction and discharge of this Indenture have been complied with. Notwithstanding the satisfaction and discharge of this Indenture, the obligations of the Company to the Trustee under Article 7 shall survive in accordance with the terms thereof.

Article 4
Particular Covenants of the Company

Section 4.01. Payment of Principal and Interest. The Company covenants and agrees that it will cause to be paid the principal (including the Redemption Price and the Fundamental Change Repurchase Price, if applicable) of, and accrued and unpaid interest on, each of the Notes at the places, at the respective times and in the manner provided herein and in the Notes.

Section 4.02. Maintenance of Office or Agency. The Company will maintain in the continental United States, an office or agency where the Notes may be surrendered for registration of transfer or exchange or for presentation for payment or repurchase (“Paying Agent”) or for conversion (“Conversion Agent”) and where notices and demands to or upon the Company in respect of the Notes and this Indenture may be made. The Company will give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office or the office or agency of the Trustee in the continental United States.

The Company may also from time to time designate as co-Note Registrars one or more other offices or agencies where the Notes may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an office or agency in the continental United States, for such purposes. The Company will give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency. The terms “Paying Agent” and “Conversion Agent” include any such additional or other offices or agencies, as applicable.

The Company hereby initially designates the Trustee as the Paying Agent, Note Registrar, Custodian and Conversion Agent and the Corporate Trust Office as the office or agency in the continental United States, where Notes may be surrendered for registration of transfer or exchange or for presentation for payment or repurchase or for conversion and where notices and demands in respect of the Notes and this Indenture may be made; provided that the Corporate Trust Office shall not be a place for service of legal process on the Company.

Section 4.03. Appointments to Fill Vacancies in Trustee’s Office. The Company, whenever necessary to avoid or fill a vacancy in the office of Trustee, will appoint, in the manner provided in Section 7.09, a Trustee, so that there shall at all times be a Trustee hereunder.

Section 4.04. Provisions as to Paying Agent. (a) If the Company shall appoint a Paying Agent other than the Trustee, the Company will cause such Paying Agent to execute and deliver to the Trustee an instrument in which such agent shall agree with the Trustee, subject to the provisions of this Section 4.04:

Price, if applicable) of, and accrued and unpaid interest on, the Notes in trust for the benefit of the Holders of the Notes;

(ii) that it will give the Trustee prompt written notice of any failure by the Company to make any payment of the principal (including the Redemption Price and the Fundamental Change Repurchase Price, if applicable) of, and accrued and unpaid interest on, the Notes when the same shall be due and payable; and

The Company shall, on or before each due date of the principal (including the Redemption Price and the Fundamental Change Repurchase Price, if applicable) of, or accrued and unpaid interest on, the Notes, deposit with the Paying Agent a sum in immediately available U.S. Dollars sufficient to pay such principal (including the Redemption Price and the Fundamental Change Repurchase Price, if applicable) or accrued and unpaid interest, and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee in writing of any failure to take such action; provided that if such deposit is made on the due date, such deposit must be received by the Paying Agent by 11:00 a.m., New York City time, on such date.

(c) Anything in this Section 4.04 to the contrary notwithstanding, the Company may, at any time, for the purpose of obtaining a satisfaction and discharge of this Indenture, or for any other reason, pay, cause to be paid or deliver to the Trustee all sums or amounts held in trust by the Company or any Paying Agent hereunder as required by this Section 4.04, such sums or amounts to be held by the Trustee upon the trusts herein contained and upon such payment or delivery by the Company or any Paying Agent to the Trustee, the Company or such Paying Agent shall be released from all further liability but only with respect to such sums or amounts. Upon the occurrence of any event specified in Section 6.01(i) or Section 6.01(j), the Trustee shall automatically become the Paying Agent.

(d) Subject to applicable law, any money or property deposited with the Trustee, the Conversion Agent or any Paying Agent, or any money and shares of Common Stock then held by the Company, in trust for the payment of the principal (including the Redemption Price and the Fundamental Change Repurchase Price, if applicable) of, accrued and unpaid interest on and

Section 4.05. Existence. Subject to Article 11, the Company shall do or cause to be done all things necessary to preserve and keep in full force and effect its corporate existence.

Section 4.06. Rule 144A Information Requirement and Annual Reports. (a) At any time the Company is not subject to Section 13 or 15(d) of the Exchange Act, the Company shall, so long as any of the Notes or any shares of Common Stock issuable upon conversion thereof shall, at such time, constitute “restricted securities” within the meaning of Rule 144(a)(3) under the Securities Act, promptly provide to the Trustee and, upon written request, any Holder, beneficial owner or prospective purchaser of such Notes or any shares of Common Stock issuable upon conversion of such Notes, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act to facilitate the resale of such Notes or shares of Common Stock pursuant to Rule 144A.

Any such document or report that the Company files with the Commission via the Commission’s EDGAR system shall be deemed to be delivered to the Trustee for purposes of this Section 4.06(b) at the time such documents are filed via the EDGAR system (or any successor thereto), it being understood that the Trustee shall not be responsible for determining whether such filings have been made.

(c) Delivery of the reports and documents described in subsection (b) above to the Trustee is for informational purposes only, and the Trustee’s receipt of such shall not constitute

31

Exhibit 4.1

constructive notice of any information contained therein or determinable from information contained therein, including the Company’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to conclusively rely on Officer’s Certificates). The Trustee shall have no liability or responsibility for the filing, timeliness or content of any such report or document.

(d) If, at any time during the six-month period beginning on, and including, the date that is six months after the Last Original Issue Date of any Notes, the Company fails to timely file any document or report that it is required to file with the Commission pursuant to Section 13 or 15(d) of the Exchange Act, as applicable (after giving effect to all applicable grace periods thereunder and other than reports on Form 8-K), or such Notes are not otherwise freely tradable pursuant to Rule 144 by Holders other than the Company’s Affiliates or Holders that were the Company’s Affiliates at any time during the three months immediately preceding (as a result of restrictions pursuant to U.S. securities laws or the terms of this Indenture or such Notes (other than any restrictive legends on the Notes issued on the date hereof)), the Company shall pay Additional Interest on such Notes. Such Additional Interest shall accrue on the Notes (i) at the rate of 0.25% per annum of the principal amount of such Notes outstanding for each day during the first 90 days of such period for which the Company’s failure to file has occurred and is continuing or such Notes are not otherwise freely tradable pursuant to Rule 144 by Holders other than the Company’s Affiliates (or Holders that were the Company’s Affiliates at any time during the three months immediately preceding) and (ii) at the rate of 0.50% per annum of the principal amount of such Notes outstanding for each day after the 90th day of such period for which the Company’s failure to file has occurred and is continuing or such Notes are not otherwise freely tradable pursuant to Rule 144 by Holders other than the Company’s Affiliates (or Holders that were the Company’s Affiliates at any time during the three months immediately preceding).

(e) If, and for so long as, the restrictive legend on any Notes specified in Section 2.05(c) has not been removed, such Notes are assigned a restricted CUSIP or such Notes are not otherwise freely tradable pursuant to Rule 144 by Holders other than the Company’s Affiliates or Holders that were the Company’s Affiliates at any time during the three months immediately preceding (without restrictions pursuant to U.S. securities laws or the terms of this Indenture or the Notes) as of the De-Legending Deadline Date for such Notes, the Company shall pay Additional Interest on such Notes at (i) a rate equal to 0.25% per annum of the principal amount of such Notes for each day during the period beginning on, and including, the De-Legending Deadline Date and ending on the earlier of (x) the 90th day immediately following the De-Legending Deadline Date and (y) the date on which the restrictive legend on such Notes has been removed in accordance with Section 2.05(c), such Notes are assigned an unrestricted CUSIP and such Notes are freely tradable pursuant to Rule 144 by Holders other than the Company’s Affiliates (or Holders that were the Company’s Affiliates at any time during the three months immediately preceding) without restrictions pursuant to U.S. securities laws or the terms of this Indenture or the Notes and (ii) at a rate equal to 0.50% per annum of the principal amount of

32

Exhibit 4.1

such Notes outstanding for each day during the period beginning on, and including, the 91st day immediately following the De-Legending Deadline Date and ending on the date on which the restrictive legend on such Notes has been removed in accordance with Section 2.05(c), such Notes are assigned an unrestricted CUSIP and such Notes are freely tradable pursuant to Rule 144 by Holders other than the Company’s Affiliates (or Holders that were the Company’s Affiliates at any time during the three months immediately preceding) without restrictions pursuant to U.S. securities laws or the terms of this Indenture or the Notes.

(f) Additional Interest will be payable in arrears on each Interest Payment Date following accrual in the same manner as regular interest on the Notes.

(g) The Additional Interest that is payable in accordance with Section 4.06(d) or Section 4.06(e) shall be in addition to, and not in lieu of, any Additional Interest that may be payable as a result of the Company’s election pursuant to Section 6.03. However, in no event shall any Additional Interest that may accrue as a result of the Company’s failure to timely file any document or report that it is required to file with the Commission pursuant to Section 13 or 15(d) of the Exchange Act, as applicable, after giving effect to all applicable grace periods thereunder and other than reports on Form 8-K), as described in Section 4.06(d), together with any Additional Interest payable at the Company’s election as the remedy for an Event of Default relating to the Company’s failure to comply with its obligations as set forth in Section 4.06(b), accrue at a rate in excess of 0.50% per annum pursuant to this Indenture, regardless of the number of events or circumstances giving rise to the requirement to pay such Additional Interest.

(h) If Additional Interest is payable by the Company pursuant to Section 4.06(d) or Section 4.06(e), the Company shall deliver to the Trustee, no later than five Business Days prior to the applicable payment date, an Officer’s Certificate to that effect stating (i) the amount of such Additional Interest that is payable and (ii) the date on which such Additional Interest is payable. Unless and until a Responsible Officer of the Trustee receives at the Corporate Trust Office such a certificate, the Trustee may assume without inquiry that no such Additional Interest is payable, and the Trustee shall not have any duty to verify the Company’s calculation of Additional Interest. If the Company has paid Additional Interest directly to the Persons entitled to it, the Company shall deliver to the Trustee an Officer’s Certificate setting forth the particulars of such payment.

Section 4.07. Stay, Extension and Usury Laws. The Company covenants (to the extent that it may lawfully do so) that it shall not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law or other law that would prohibit or forgive the Company from paying all or any portion of the principal of or interest on the Notes as contemplated herein, wherever enacted, now or at any time hereafter in force, or that may affect the covenants or the performance of this Indenture; and the Company (to the extent it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and covenants that it will not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted.

(h) [reserved];

(i) the Company or any Material Subsidiary shall commence a voluntary case or other proceeding seeking liquidation, reorganization or other relief with respect to the Company or any such Material Subsidiary or its debts under any bankruptcy, insolvency or other similar law now or hereafter in effect or seeking the appointment of a trustee, receiver, liquidator, custodian or other similar official of the Company or any such Material Subsidiary or any substantial part of its property, or shall consent to any such relief or to the appointment of or taking possession by any such official in an involuntary case or other proceeding commenced against it, or shall make a general assignment for the benefit of creditors, or shall fail generally to pay its debts as they become due; or

35

Exhibit 4.1

(j) an involuntary case or other proceeding shall be commenced against the Company or any Material Subsidiary seeking liquidation, reorganization or other relief with respect to the Company or such Material Subsidiary or its debts under any bankruptcy, insolvency or other similar law now or hereafter in effect or seeking the appointment of a trustee, receiver, liquidator, custodian or other similar official of the Company or such Material Subsidiary or any substantial part of its property, and such involuntary case or other proceeding shall remain undismissed and unstayed for a period of 60 consecutive days.

Section 6.02. Acceleration; Rescission and Annulment. If one or more Events of Default shall have occurred and be continuing (whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body), then, and in each and every such case (other than an Event of Default specified in Section 6.01(i) or Section 6.01(j) with respect to the Company), unless the principal of all of the Notes shall have already become due and payable, either the Trustee or the Holders of at least 25% in aggregate principal amount of the Notes then outstanding determined in accordance with Section 8.04, by notice in writing to the Company (and to the Trustee if given by Holders), may declare 100% of the principal of, and accrued and unpaid interest on, all the Notes to be due and payable immediately, and upon any such declaration the same shall become and shall automatically be immediately due and payable, anything contained in this Indenture or in the Notes to the contrary notwithstanding. If an Event of Default specified in Section 6.01(i) or Section 6.01(j) with respect to the Company (and not involving solely one or more of its Material Subsidiaries) occurs and is continuing, 100% of the principal of, and accrued and unpaid interest, if any, on, all Notes shall become and shall automatically be immediately due and payable.

The immediately preceding paragraph, however, is subject to the conditions that if, at any time after the principal of the Notes shall have been so declared due and payable, and before any judgment or decree for the payment of the monies due shall have been obtained or entered as hereinafter provided, the Company shall pay or shall deposit with the Trustee a sum sufficient to pay installments of accrued and unpaid interest upon all Notes and the principal of any and all Notes that shall have become due otherwise than by acceleration (with interest on overdue installments of accrued and unpaid interest to the extent that payment of such interest is enforceable under applicable law, and on such principal at the rate borne by the Notes at such time) and amounts due to the Trustee pursuant to Section 7.06, and if (1) rescission would not conflict with any judgment or decree of a court of competent jurisdiction and (2) any and all existing Events of Default, other than the nonpayment of the principal of and accrued and unpaid interest, if any, on Notes that shall have become due solely by such acceleration, shall have been cured or waived pursuant to Section 6.09, then and in every such case (except as provided in the immediately succeeding sentence) the Holders of a majority in aggregate principal amount of the Notes then outstanding, by written notice to the Company and to the Trustee, may waive all Defaults or Events of Default with respect to the Notes and rescind and annul such declaration and its consequences and such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of this Indenture; but no such waiver or rescission and annulment shall extend to or shall affect any subsequent Default or

36

Exhibit 4.1

Event of Default, or shall impair any right consequent thereon. Notwithstanding anything to the contrary herein, no such waiver or rescission and annulment shall extend to or shall affect any Default or Event of Default resulting from (i) the nonpayment of the principal (including the Redemption Price and the Fundamental Change Repurchase Price, if applicable) of, or accrued and unpaid interest on, any Notes, (ii) a failure to repurchase any Notes when required or (iii) a failure to pay or deliver, as the case may be, the consideration due upon conversion of the Notes.

Section 6.03. Additional Interest. Notwithstanding anything in this Indenture or in the Notes to the contrary, to the extent the Company elects, the sole remedy for an Event of Default relating to the Company’s failure to comply with its obligations as set forth in Section 4.06(b) shall after the occurrence of such an Event of Default consist exclusively of the right to receive Additional Interest on the Notes at a rate equal to: (i) 0.25% per annum of the principal amount of the Notes outstanding for each day during the period beginning on, and including, the date on which such Event of Default first occurs and ending on the earlier of (x) the date on which such Event of Default is cured or validly waived in accordance with this Article 6 and (y) the 180th day immediately following, and including, the date on which such Event of Default first occurs and (ii) if such Event of Default has not been cured or validly waived prior to the 181st day immediately following, and including, the date on which such Event of Default first occurs, 0.50% per annum of the principal amount of Notes outstanding for each day during the period beginning on, and including, the 181st day immediately following, and including, the date on which such Event of Default first occurs and ending on the earlier of (x) the date on which the Event of Default is cured or validly waived in accordance with this Article 6 and (y) the 360th day immediately following, and including, the date on which such event of default first occurs. Additional Interest payable pursuant to this Section 6.03 shall be in addition to, not in lieu of, any Additional Interest payable pursuant to Section 4.06(d) or Section 4.06(e), subject to the second immediately succeeding paragraph. If the Company so elects, such Additional Interest shall be payable in the same manner and on the same dates as the stated interest payable on the Notes. On the 361st day after such Event of Default (if the Event of Default relating to the Company’s failure to file is not cured or waived prior to such 361st day), the Notes shall be immediately subject to acceleration as provided in Section 6.02. The provisions of this paragraph will not affect the rights of Holders of Notes in the event of the occurrence of any Event of Default other than the Company’s failure to comply with its obligations as set forth in ‎Section 4.06(b). In the event the Company does not elect to pay Additional Interest following an Event of Default in accordance with this Section 6.03 or the Company elected to make such payment but does not pay the Additional Interest when due, the Notes shall be immediately subject to acceleration as provided in Section 6.02.

In order to elect to pay Additional Interest as the sole remedy during the first 360 days after the occurrence of any Event of Default described in the immediately preceding paragraph, the Company must notify all Holders of the Notes, the Trustee and the Paying Agent in writing of such election prior to the beginning of such 360-day period. Upon the failure to timely give such notice, the Notes shall be immediately subject to acceleration as provided in Section 6.02.

In no event shall Additional Interest payable at the Company’s election as the remedy for an Event of Default relating to the Company’s failure to comply with its obligations as set forth

37

Exhibit 4.1

in Section 4.06(b), together with any Additional Interest that may accrue as a result of the Company’s failure to timely file any document or report that it is required to file with the Commission pursuant to Section 13 or 15(d) of the Exchange Act, as applicable (after giving effect to all applicable grace periods thereunder and other than reports on Form 8-K), pursuant to Section 4.06(d), accrue at a rate in excess of 0.50% per annum pursuant to this Indenture, regardless of the number of events or circumstances giving rise to the requirement to pay such Additional Interest. The Trustee shall have no duty to calculate or verify the calculation of Additional Interest. The Company shall send written notice to the Holder of each Note and the Trustee of the commencement and termination of any period on which Additional Interest accrues on such Note under any provision of this Indenture.

Section 6.04. Payments of Notes on Default; Suit Therefor. If an Event of Default described in clause (a) or (b) of Section 6.01 shall have occurred, the Company shall, upon demand of the Trustee, pay to the Trustee, for the benefit of the Holders of the Notes, the whole amount then due and payable on the Notes for principal and interest, if any, with interest on any overdue principal and interest, if any, at the rate borne by the Notes at such time, and, in addition thereto, such further amount as shall be sufficient to cover any amounts due to the Trustee under Section 7.06. If the Company shall fail to pay such amounts forthwith upon such demand, the Trustee, in its own name and as trustee of an express trust, may institute a judicial proceeding for the collection of the sums so due and unpaid, may prosecute such proceeding to judgment or final decree and may enforce the same against the Company or any other obligor upon the Notes and collect the moneys adjudged or decreed to be payable in the manner provided by law out of the property of the Company or any other obligor upon the Notes, wherever situated.

In the event there shall be pending proceedings for the bankruptcy or for the reorganization of the Company or any other obligor on the Notes under Title 11 of the United States Code, or any other applicable law, or in case a receiver, assignee or trustee in bankruptcy or reorganization, liquidator, sequestrator or similar official shall have been appointed for or taken possession of the Company or such other obligor, the property of the Company or such other obligor, or in the event of any other judicial proceedings relative to the Company or such other obligor upon the Notes, or to the creditors or property of the Company or such other obligor, the Trustee, irrespective of whether the principal of the Notes shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand pursuant to the provisions of this Section 6.04, shall be entitled and empowered, by intervention in such proceedings or otherwise, to file and prove a claim or claims for the whole amount of principal and accrued and unpaid interest, if any, in respect of the Notes, and, in case of any judicial proceedings, to file such proofs of claim and other papers or documents and to take such other actions as it may deem necessary or advisable in order to have the claims of the Trustee (including any claim for the compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and of the Holders allowed in such judicial proceedings relative to the Company or any other obligor on the Notes, its or their creditors, or its or their property, and to collect and receive any monies or other property payable or deliverable on any such claims, and to distribute the same after the deduction of any amounts due to the Trustee under Section 7.06; and any receiver, assignee or trustee in bankruptcy or reorganization, liquidator, custodian or similar official is hereby authorized by each of the

38

Exhibit 4.1

Holders to make such payments to the Trustee, as administrative expenses, and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due it for reasonable compensation, expenses, advances and disbursements, including reasonable agents and counsel fees, and including any other amounts due to the Trustee under Section 7.06, incurred by it up to the date of such distribution. To the extent that such payment of compensation, expenses, advances and disbursements out of the estate in any such proceedings shall be denied for any reason, payment of the same shall be secured by a lien on, and shall be paid out of, any and all distributions, dividends, monies, securities and other property that the Holders of the Notes may be entitled to receive in such proceedings, whether in liquidation or under any plan of reorganization or arrangement or otherwise.

Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting such Holder or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

All rights of action and of asserting claims under this Indenture, or under any of the Notes, may be enforced by the Trustee without the possession of any of the Notes, or the production thereof at any trial or other proceeding relative thereto, and any such suit or proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders of the Notes.

In any proceedings brought by the Trustee (and in any proceedings involving the interpretation of any provision of this Indenture to which the Trustee shall be a party) the Trustee shall be held to represent all the Holders of the Notes, and it shall not be necessary to make any Holders of the Notes parties to any such proceedings.

In case the Trustee shall have proceeded to enforce any right under this Indenture and such proceedings shall have been discontinued or abandoned because of any waiver pursuant to Section 6.09 or any rescission and annulment pursuant to Section 6.02 or for any other reason or shall have been determined adversely to the Trustee, then and in every such case the Company, the Holders and the Trustee shall, subject to any determination in such proceeding, be restored respectively to their several positions and rights hereunder, and all rights, remedies and powers of the Company, the Holders and the Trustee shall continue as though no such proceeding had been instituted.

Section 6.05. Application of Monies Collected by Trustee. Any monies or property collected by the Trustee pursuant to this Article 6 with respect to the Notes shall be applied in the following order, at the date or dates fixed by the Trustee for the distribution of such monies or property, upon presentation of the several Notes, and stamping thereon the payment, if only partially paid, and upon surrender thereof, if fully paid:

First, to the payment of all amounts due the Trustee and the Agents hereunder;

39

Exhibit 4.1

Second, in case the principal of the outstanding Notes shall not have become due and be unpaid, to the payment of interest on, and any cash due upon conversion of, the Notes in default in the order of the date due of the payments of such interest and cash due upon conversion, as the case may be, with interest (to the extent that such interest has been collected by the Trustee) upon such overdue payments at the rate borne by the Notes at such time, such payments to be made ratably to the Persons entitled thereto;

Third, in case the principal of the outstanding Notes shall have become due, by declaration or otherwise, and be unpaid to the payment of the whole amount (including, if applicable, the payment of the Redemption Price and the Fundamental Change Repurchase Price and any cash due upon conversion) then owing and unpaid upon the Notes for principal and interest, if any, with interest on the overdue principal and, to the extent that such interest has been collected by the Trustee, upon overdue installments of interest at the rate borne by the Notes at such time, and in case such monies shall be insufficient to pay in full the whole amounts so due and unpaid upon the Notes, then to the payment of such principal (including, if applicable, the Redemption Price and the Fundamental Change Repurchase Price and any cash due upon conversion) and interest without preference or priority of principal over interest, or of interest over principal or of any installment of interest over any other installment of interest, or of any Note over any other Note, ratably to the aggregate of such principal (including, if applicable, the Redemption Price and the Fundamental Change Repurchase Price and any cash due upon conversion) and accrued and unpaid interest; and

Fourth, to the payment of the remainder, if any, to the Company.

Section 6.06. Proceedings by Holders. Except to enforce the right to receive payment of principal (including, if applicable, the Redemption Price and the Fundamental Change Repurchase Price) or interest when due, or the right to receive payment or delivery of the consideration due upon conversion, no Holder of any Note shall have any right by virtue of or by availing of any provision of this Indenture to institute any suit, action or proceeding in equity or at law upon or under or with respect to this Indenture, or for the appointment of a receiver, trustee, liquidator, custodian or other similar official, or for any other remedy hereunder, unless:

(a) such Holder previously shall have given to the Trustee written notice of an Event of Default and of the continuance thereof, as herein provided;

(b) Holders of at least 25% in aggregate principal amount of the Notes then outstanding shall have made written request upon the Trustee to institute such action, suit or proceeding in its own name as Trustee hereunder;

(c) such Holders shall have offered to the Trustee such security or indemnity satisfactory to the Trustee against any loss, liability or expense to be incurred therein or thereby;

(d) the Trustee has not complied with such request within 60 days after receipt of the request and the offer of such security or indemnity; and

40

Exhibit 4.1

(e) no direction that, in the opinion of the Trustee, is inconsistent with such written request shall have been given to the Trustee by the Holders of a majority of the aggregate principal amount of the Notes then outstanding within such 60-day period pursuant to Section 6.09,

it being understood and intended, and being expressly covenanted by the taker and Holder of every Note with every other taker and Holder and the Trustee that no one or more Holders shall have any right in any manner whatever by virtue of or by availing of any provision of this Indenture to affect, disturb or prejudice the rights of any other Holder, or to obtain or seek to obtain priority over or preference to any other such Holder, or to enforce any right under this Indenture, except in the manner herein provided and for the equal, ratable and common benefit of all Holders (except as otherwise provided herein) (it being understood that the Trustee shall have no obligation to determine whether any such action or inaction would unduly prejudice the rights of another Holder). For the protection and enforcement of this Section 6.06, each and every Holder and the Trustee shall be entitled to such relief as can be given either at law or in equity.

Notwithstanding any other provision of this Indenture and any provision of any Note, each Holder shall have the right to institute suit for the enforcement of its right to receive payment or delivery, as the case may be, of (x) the principal (including the Redemption Price and the Fundamental Change Repurchase Price, if applicable) of, (y) accrued and unpaid interest, if any, on, and (z) the consideration due upon conversion of, such Note, on or after the respective due dates expressed or provided for in such Note or in this Indenture.

Section 6.07. Proceedings by Trustee. In case of an Event of Default, the Trustee may in its discretion proceed to protect and enforce the rights vested in it by this Indenture by such appropriate judicial proceedings as are necessary to protect and enforce any of such rights, either by suit in equity or by action at law or by proceeding in bankruptcy or otherwise, whether for the specific enforcement of any covenant or agreement contained in this Indenture or in aid of the exercise of any power granted in this Indenture, or to enforce any other legal or equitable right vested in the Trustee by this Indenture or by law.

Section 6.08. Remedies Cumulative and Continuing. Except as provided in the last paragraph of Section 2.06, all powers and remedies given by this Article 6 to the Trustee or to the Holders shall, to the extent permitted by law, be deemed cumulative and not exclusive of any thereof or of any other powers and remedies available to the Trustee or the Holders of the Notes, by judicial proceedings or otherwise, to enforce the performance or observance of the covenants and agreements contained in this Indenture, and no delay or omission of the Trustee or of any Holder of any of the Notes to exercise any right or power accruing upon any Default or Event of Default shall impair any such right or power, or shall be construed to be a waiver of any such Default or Event of Default or any acquiescence therein; and, subject to the provisions of Section 6.06, every power and remedy given by this Article 6 or by law to the Trustee or to the Holders may be exercised from time to time, and as often as shall be deemed expedient, by the Trustee or by the Holders.

41

Exhibit 4.1

Section 6.09. Direction of Proceedings and Waiver of Defaults by Majority of Holders. The Holders of a majority of the aggregate principal amount of the Notes at the time outstanding determined in accordance with Section 8.04 shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee with respect to the Notes; provided, however, that (a) such direction shall not be in conflict with any rule of law or with this Indenture, and (b) the Trustee may take any other action deemed proper by the Trustee that is not inconsistent with such direction. The Trustee may refuse to follow any direction that it determines is unduly prejudicial to the rights of any other Holder or that would involve the Trustee in personal liability (it being understood that the Trustee shall not have an affirmative duty to ascertain whether or not any such direction is unduly prejudicial to any other Holder) or for which it has not received indemnity or security satisfactory to the Trustee against any loss, liability or expense. The Holders of a majority in aggregate principal amount of the Notes at the time outstanding determined in accordance with Section 8.04 may on behalf of the Holders of all of the Notes waive any past Default or Event of Default hereunder and its consequences except (i) a default in the payment of accrued and unpaid interest, if any, on, or the principal (including any Redemption Price and any Fundamental Change Repurchase Price) of, the Notes when due that has not been cured pursuant to the provisions of Section 6.01, (ii) a failure by the Company to repurchase any Notes when required or to pay or deliver, as the case may be, the consideration due upon conversion of the Notes or (iii) a default in respect of a covenant or provision hereof which under Article 10 cannot be modified or amended without the consent of each Holder of an outstanding Note affected. Upon any such waiver the Company, the Trustee and the Holders of the Notes shall be restored to their former positions and rights hereunder; but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon. Whenever any Default or Event of Default hereunder shall have been waived as permitted by this Section 6.09, said Default or Event of Default shall for all purposes of the Notes and this Indenture be deemed to have been cured and to be not continuing; but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon.

Section 6.10. Notice of Defaults. The Trustee shall, within 90 days after the Trustee has received written notice of the occurrence and continuance of a Default of which a Responsible Officer has actual knowledge, deliver to all Holders notice of all such Defaults, unless such Defaults shall have been cured or waived before the giving of such notice; provided that, except in the case of a Default in the payment of the principal of (including the Redemption Price and the Fundamental Change Repurchase Price, if applicable), or accrued and unpaid interest on, any of the Notes or a Default in the payment or delivery of the consideration due upon conversion, the Trustee shall be protected in withholding such notice if and so long as the Trustee in good faith determines that the withholding of such notice is in the interests of the Holders.

Section 6.11. Undertaking to Pay Costs. All parties to this Indenture agree, and each Holder of any Note by its acceptance thereof shall be deemed to have agreed, that any court may, in its discretion, require, in any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action taken or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit and that

42

Exhibit 4.1

such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; provided that the provisions of this Section 6.11 (to the extent permitted by law) shall not apply to any suit instituted by the Trustee, to any suit instituted by any Holder, or group of Holders, holding in the aggregate more than 10% in principal amount of the Notes at the time outstanding determined in accordance with Section 8.04, or to any suit instituted by any Holder for the enforcement of the payment of the principal of or accrued and unpaid interest, if any, on any Note (including, but not limited to, the Redemption Price and the Fundamental Change Repurchase Price, if applicable) on or after the due date expressed or provided for in such Note or to any suit for the enforcement of the right to convert any Note, or receive the consideration due upon conversion, in accordance with the provisions of Article 14.

Article 7
Concerning the Trustee

Section 7.01. Duties and Responsibilities of Trustee. The Trustee, prior to the occurrence of an Event of Default and after the curing or waiver of all Events of Default (for which a Responsible Officer of the Trustee has written notice or actual knowledge) that may have occurred, undertakes to perform such duties and only such duties as are specifically set forth in this Indenture. In the event an Event of Default has occurred and is continuing, the Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in its exercise, as a prudent person would exercise or use under the circumstances in the conduct of such person’s own affairs; provided that the Trustee will be under no obligation to exercise any of the rights or powers under this Indenture at the request or direction of any of the Holders unless such Holders have offered, and, if requested, provided to the Trustee indemnity or security satisfactory to the Trustee against any loss, liability or expense that might be incurred by it in compliance with such request or direction.

No provision of this Indenture shall be construed to relieve the Trustee from liability for its own grossly negligent action, its own grossly negligent failure to act or its own willful misconduct, except that:

47

Exhibit 4.1

connection with the acceptance or administration of this Indenture or in any other capacity hereunder, including the costs and expenses of defending themselves against any claim of liability. The obligations of the Company under this Section 7.06 to compensate or indemnify the Trustee and to pay or reimburse the Trustee for expenses, disbursements and advances shall be secured by a senior lien and claim to which the Notes are hereby made subordinate on all money or property held or collected by the Trustee, except, subject to the effect of Section 6.05, funds held in trust herewith for the benefit of the Holders of particular Notes. The Trustee’s right to receive payment of any amounts due under this Section 7.06 shall not be subordinate to any other liability or indebtedness of the Company. The obligation of the Company under this Article 7 shall survive the satisfaction and discharge of this Indenture and the earlier resignation or removal of the Trustee. The Company need not pay for any settlement made without its consent, which consent shall not be unreasonably withheld. The indemnification provided in this Section 7.06 shall extend to the officers, directors, agents and employees of the Trustee.

Without prejudice to any other rights available to the Trustee under applicable law, when the Trustee and its agents and any authenticating agent incur expenses or render services after an Event of Default specified in Section 6.01(i) or Section 6.01(j) occurs, the expenses and the compensation for the services are intended to constitute expenses of administration under any bankruptcy, insolvency or similar laws.

Section 7.07. Officer’s Certificate and Opinion of Counsel as Evidence. Except as otherwise provided in Section 7.01, whenever in the administration of the provisions of this Indenture the Trustee shall deem it necessary or desirable that a matter be proved or established prior to taking or omitting any action hereunder, such matter (unless other evidence in respect thereof be herein specifically prescribed) may be deemed to be conclusively proved and established by an Officer’s Certificate and Opinion of Counsel delivered to the Trustee, and such Officer’s Certificate and Opinion of Counsel shall be full warrant to the Trustee for any action taken or omitted by it under the provisions of this Indenture upon the faith thereof.

Section 7.08. Eligibility of Trustee. There shall at all times be a Trustee hereunder which shall be a Person that is eligible pursuant to the Trust Indenture Act (as if the Trust Indenture Act were applicable hereto) to act as such and has a combined capital and surplus of at least $50,000,000. If such Person publishes reports of condition at least annually, pursuant to law or to the requirements of any supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such Person shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time the Trustee shall cease to be eligible in accordance with the provisions of this Section, it shall resign immediately in the manner and with the effect hereinafter specified in this Article.

Section 7.09. Resignation or Removal of Trustee. (a) The Trustee may at any time resign by giving 30 days’ written notice of such resignation to the Company and by delivering notice thereof to the Holders. Upon receiving such notice of resignation, the Company shall promptly appoint a successor trustee by written instrument, in duplicate, executed by order of the Board of Directors, one copy of which instrument shall be delivered to the resigning Trustee and one copy to the successor trustee. If no successor trustee shall have been so appointed and have accepted

48

Exhibit 4.1

appointment within 30 days after the giving of such notice of resignation to the Holders, the resigning Trustee may, upon ten Business Days’ notice to the Company and the Holders, petition any court of competent jurisdiction for the appointment of a successor trustee, or any Holder who has been a bona fide holder of a Note or Notes for at least six months (or since the date of this Indenture) may, subject to the provisions of Section 6.11, on behalf of himself or herself and all others similarly situated, petition any such court for the appointment of a successor trustee at the cost of the Company. Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, appoint a successor trustee.

(b) In case at any time any of the following shall occur:

(i) the Trustee shall cease to be eligible in accordance with the provisions of Section 7.08 and shall fail to resign after written request therefor by the Company or by any such Holder, or

(ii) the Trustee shall become incapable of acting, or shall be adjudged a bankrupt or insolvent, or a receiver of the Trustee or of its property shall be appointed, or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation,

then, in either case, the Company may, upon 30 days’ written notice to the Trustee, by a Board Resolution, remove the Trustee and appoint a successor trustee by written instrument, in duplicate, executed by order of the Board of Directors, one copy of which instrument shall be delivered to the Trustee so removed and one copy to the successor trustee, or, subject to the provisions of Section 6.11, any Holder who has been a bona fide holder of a Note or Notes for at least six months (or since the date of this Indenture) may, on behalf of himself or herself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor trustee. Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, remove the Trustee and appoint a successor trustee.

(c) The Holders of a majority in aggregate principal amount of the Notes at the time outstanding, as determined in accordance with Section 8.04, may, upon 30 days’ written notice to the Trustee, remove the Trustee and nominate a successor trustee that shall be deemed appointed as successor trustee unless within ten days after notice to the Company of such nomination the Company objects thereto (and no Event of Default shall have occurred and be continuing), in which case the Trustee so removed or any Holder, upon the terms and conditions and otherwise as in Section 7.09(a) provided, may petition any court of competent jurisdiction for an appointment of a successor trustee at the cost of the Company.

(d) Any resignation or removal of the Trustee and appointment of a successor trustee pursuant to any of the provisions of this Section 7.09 shall become effective upon acceptance of appointment by the successor trustee as provided in Section 7.10.

Section 7.10. Acceptance by Successor Trustee. Any successor trustee appointed as provided in Section 7.09 shall execute, acknowledge and deliver to the Company and to its predecessor trustee an instrument accepting such appointment hereunder, and thereupon the

49

Exhibit 4.1

resignation or removal of the predecessor trustee shall become effective and such successor trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, duties and obligations of its predecessor hereunder, with like effect as if originally named as Trustee herein; but, nevertheless, on the written request of the Company or of the successor trustee, the trustee ceasing to act shall, upon payment of any amounts then due it pursuant to the provisions of Section 7.06, execute and deliver an instrument transferring to such successor trustee all the rights and powers of the trustee so ceasing to act. Upon request of any such successor trustee, the Company shall execute any and all instruments in writing for more fully and certainly vesting in and confirming to such successor trustee all such rights and powers. Any trustee ceasing to act shall, nevertheless, retain a senior lien and claim to which the Notes are hereby made subordinate on all money or property held or collected by such trustee as such, except for funds held in trust for the benefit of Holders of particular Notes, to secure any amounts then due it pursuant to the provisions of Section 7.06.

No successor trustee shall accept appointment as provided in this Section 7.10 unless at the time of such acceptance such successor trustee shall be eligible under the provisions of Section 7.08.

Upon acceptance of appointment by a successor trustee as provided in this Section 7.10, each of the Company and the successor trustee, at the written direction and at the expense of the Company shall deliver or cause to be delivered notice of the succession of such trustee hereunder to the Holders. If the Company fails to deliver such notice within ten days after acceptance of appointment by the successor trustee, the successor trustee shall cause such notice to be delivered at the expense of the Company.

Section 7.11. Succession by Merger, Etc. Any corporation or other entity into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation or other entity resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation or other entity succeeding to all or substantially all of the corporate trust business of the Trustee (including the administration of this Indenture), shall be the successor to the Trustee hereunder without the execution or filing of any paper or any further act on the part of any of the parties hereto; provided that in the case of any corporation or other entity succeeding to all or substantially all of the corporate trust business of the Trustee such corporation or other entity shall be eligible under the provisions of Section 7.08.

In case at the time such successor to the Trustee shall succeed to the trusts created by this Indenture, any of the Notes shall have been authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor trustee or authenticating agent appointed by such predecessor trustee, and deliver such Notes so authenticated; and in case at that time any of the Notes shall not have been authenticated, any successor to the Trustee or an authenticating agent appointed by such successor trustee may authenticate such Notes either in the name of any predecessor trustee hereunder or in the name of the successor trustee; and in all such cases such certificates shall have the full force which it is anywhere in the Notes or in this Indenture provided that the certificate of the Trustee shall have; provided, however, that the right to adopt the certificate of authentication of any predecessor

50

Exhibit 4.1

trustee or to authenticate Notes in the name of any predecessor trustee shall apply only to its successor or successors by merger, conversion or consolidation.

Section 7.12. Trustee’s Application for Instructions from the Company. Any application by the Trustee for written instructions from the Company (other than with regard to any action proposed to be taken or omitted to be taken by the Trustee that affects the rights of the Holders of the Notes under this Indenture) may, at the option of the Trustee, set forth in writing any action proposed to be taken or omitted by the Trustee under this Indenture and the date on and/or after which such action shall be taken or such omission shall be effective. The Trustee shall not be liable to the Company for any action taken by, or omission of, the Trustee in accordance with a proposal included in such application on or after the date specified in such application (which date shall not be less than three Business Days after notice that the Company has been deemed to have been given pursuant to Section 17.03, unless any such officer shall have consented in writing to any earlier date), unless, prior to taking any such action (or the effective date in the case of any omission), the Trustee shall have received written instructions in accordance with this Indenture in response to such application specifying the action to be taken or omitted.

Article 8
Concerning the Holders

Section 8.01. Action by Holders. Whenever in this Indenture it is provided that the Holders of a specified percentage of the aggregate principal amount of the Notes may take any action (including the making of any demand or request, the giving of any notice, consent or waiver or the taking of any other action), the fact that at the time of taking any such action, the Holders of such specified percentage have joined therein may be evidenced (a) by any instrument or any number of instruments of similar tenor executed by Holders in person or by agent or proxy appointed in writing, or (b) by the record of the Holders voting in favor thereof at any meeting of Holders duly called and held in accordance with the provisions of Article 9, or (c) by a combination of such instrument or instruments and any such record of such a meeting of Holders. Whenever the Company or the Trustee solicits the taking of any action by the Holders of the Notes, the Company or the Trustee may, but shall not be required to, fix in advance of such solicitation, a date as the record date for determining Holders entitled to take such action. The record date if one is selected shall be not more than fifteen days prior to the date of commencement of solicitation of such action.

Section 8.02. Proof of Execution by Holders. Subject to the provisions of Section 7.01, Section 7.02 and Section 9.05, proof of the execution of any instrument by a Holder or its agent or proxy shall be sufficient if made in accordance with such reasonable rules and regulations as may be prescribed by the Trustee or in such manner as shall be satisfactory to the Trustee. The holding of Notes shall be proved by the Note Register or by a certificate of the Note Registrar. The record of any Holders’ meeting shall be proved in the manner provided in Section 9.06.

Section 8.03. Who Are Deemed Absolute Owners. The Company, the Trustee, any authenticating agent, any Paying Agent, any Conversion Agent and any Note Registrar may deem the Person in whose name a Note shall be registered upon the Note Register to be, and may

51

Exhibit 4.1

treat it as, the absolute owner of such Note (whether or not such Note shall be overdue and notwithstanding any notation of ownership or other writing thereon made by any Person other than the Company or any Note Registrar) for the purpose of receiving payment of or on account of the principal (including any Redemption Price and any Fundamental Change Repurchase Price) of and (subject to Section 2.03) accrued and unpaid interest on such Note, for conversion of such Note and for all other purposes; and neither the Company nor the Trustee nor any Paying Agent nor any Conversion Agent nor any Note Registrar shall be affected by any notice to the contrary. The sole registered holder of a Global Note shall be the Depositary or its nominee. All such payments or deliveries so made to any Holder for the time being, or upon its order, shall be valid, and, to the extent of the sums or shares of Common Stock so paid or delivered, effectual to satisfy and discharge the liability for monies payable or shares deliverable upon any such Note. Notwithstanding anything to the contrary in this Indenture or the Notes following an Event of Default, any holder of a beneficial interest in a Global Note may directly enforce against the Company, without the consent, solicitation, proxy, authorization or any other action of the Depositary or any other Person, such holder’s right to exchange such beneficial interest for a Note in certificated form in accordance with the provisions of this Indenture.

Section 8.04. Company-Owned Notes Disregarded. In determining whether the Holders of the requisite aggregate principal amount of Notes have concurred in any direction, consent, waiver or other action under this Indenture, Notes that are owned by the Company, by any Subsidiary thereof or by any Affiliate of the Company or any Subsidiary thereof shall be disregarded and deemed not to be outstanding for the purpose of any such determination; provided that for the purposes of determining whether the Trustee shall be protected in relying on any such direction, consent, waiver or other action only Notes that a Responsible Officer knows are so owned shall be so disregarded. Notes so owned that have been pledged in good faith may be regarded as outstanding for the purposes of this Section 8.04 if the pledgee shall establish to the satisfaction of the Trustee the pledgee’s right to so act with respect to such Notes and that the pledgee is not the Company, a Subsidiary thereof or an Affiliate of the Company or a Subsidiary thereof. In the case of a dispute as to such right, any decision by the Trustee taken upon the advice of counsel shall be full protection to the Trustee. Upon request of the Trustee, the Company shall furnish to the Trustee promptly an Officer’s Certificate listing and identifying all Notes, if any, known by the Company to be owned or held by or for the account of any of the above described Persons; and, subject to Section 7.01, the Trustee shall be entitled to accept such Officer’s Certificate as conclusive evidence of the facts therein set forth and of the fact that all Notes not listed therein are outstanding for the purpose of any such determination.

Section 8.05. Revocation of Consents; Future Holders Bound. At any time prior to (but not after) the evidencing to the Trustee, as provided in Section 8.01, of the taking of any action by the Holders of the percentage of the aggregate principal amount of the Notes specified in this Indenture in connection with such action, any Holder of a Note that is shown by the evidence to be included in the Notes the Holders of which have consented to such action may, by filing written notice with the Trustee at its Corporate Trust Office and upon proof of holding as provided in Section 8.02, revoke such action so far as concerns such Note. Except as aforesaid, any such action taken by the Holder of any Note shall be conclusive and binding upon such Holder and upon all future Holders and owners of such Note and of any Notes issued in

52

Exhibit 4.1

exchange or substitution therefor or upon registration of transfer thereof, irrespective of whether any notation in regard thereto is made upon such Note or any Note issued in exchange or substitution therefor or upon registration of transfer thereof.

The record shall be signed and verified by the affidavits of the permanent chairman and secretary of the meeting and one of the duplicates shall be delivered to the Company and the other to the Trustee to be preserved by the Trustee, the latter to have attached thereto the ballots voted at the meeting.

Any record so signed and verified shall be conclusive evidence of the matters therein stated.

Section 9.07. No Delay of Rights by Meeting. Nothing contained in this Article 9 shall be deemed or construed to authorize or permit, by reason of any call of a meeting of Holders or any rights expressly or impliedly conferred hereunder to make such call, any hindrance or delay in the exercise of any right or rights conferred upon or reserved to the Trustee or to the Holders under any of the provisions of this Indenture or of the Notes.

Article 10
Supplemental Indentures

Section 10.01. Supplemental Indentures Without Consent of Holders. Notwithstanding anything to the contrary in Section 10.02, the Company, when authorized by the resolutions of the Board of Directors, and the Trustee, at the Company’s expense, may from time to time and at any time enter into an indenture or indentures supplemental hereto for one or more of the following purposes:

(a) to cure any ambiguity, omission, defect or inconsistency;

(b) to provide for the assumption by a Successor Entity of the obligations of the Company under this Indenture pursuant to Article 11;

(d) to secure the Notes;

(e) to add to the covenants or Events of Default of the Company for the benefit of the Holders or surrender any right or power conferred upon the Company;

(f) to make any change that does not adversely affect the rights of any Holder;

(g) to irrevocably elect a Settlement Method and/or Specified Dollar Amount (or a minimum Specified Dollar Amount) or eliminate the Company’s right to elect a Settlement Method; provided, however, that (i) no such election or elimination shall affect any Settlement Method theretofore elected (or deemed to be elected) with respect to any Note pursuant to Section 14.02 and (ii) such irrevocable election or elimination can in no event result in a

55

Exhibit 4.1

Specified Dollar Amount of less than $1,000 per $1,000 principal amount of Notes applying to the conversion of any Note;

(h) in connection with any Share Exchange Event, to provide that the Notes are convertible into units of Reference Property, subject to the provisions of Section 14.02, and make such related changes to the terms of the Notes to the extent expressly required by Section 14.07;

(i) to conform the provisions of this Indenture or the Notes to the “Description of Notes” section of the Offering Memorandum; or

(j) to comply with the rules of the Depositary.

Upon the written request of the Company, the Trustee is hereby authorized to join with the Company in the execution of any such supplemental indenture, but the Trustee shall not be obligated to, but may in its discretion, enter into any supplemental indenture that affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise.

Any supplemental indenture authorized by the provisions of this Section 10.01 may be executed by the Company and the Trustee without the consent of the Holders of any of the Notes at the time outstanding, notwithstanding any of the provisions of Section 10.02.

Section 10.02. Supplemental Indentures with Consent of Holders. With the consent (evidenced as provided in Article 8) of the Holders of at least a majority of the aggregate principal amount of the Notes then outstanding (determined in accordance with Article 8 and including, without limitation, consents obtained in connection with a repurchase of, or tender or exchange offer for, Notes), the Company, when authorized by the resolutions of the Board of Directors and the Trustee, at the Company’s expense, may from time to time and at any time enter into an indenture or indentures supplemental hereto for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of this Indenture or any supplemental indenture or of modifying in any manner the rights of the Holders; provided, however, that, without the consent of each Holder of an outstanding Note affected, no such supplemental indenture shall:

(a) reduce the amount of Notes whose Holders must consent to an amendment;

(b) reduce the rate of or extend the stated time for payment of interest on any Note;

(c) reduce the principal of or extend the Maturity Date of any Note;

(d) make any change that adversely affects the conversion rights of any Notes;

(e) reduce the Redemption Price or the Fundamental Change Repurchase Price of any Note or amend or modify in any manner adverse to the Holders the Company’s obligation to make such payments, or the Company’s right to redeem the Notes, whether through an amendment or waiver of provisions in the covenants, definitions or otherwise;

56

Exhibit 4.1

(f) make any Note payable in a currency, or at a place of payment, other than that stated in the Note;

(g) change the ranking of the Notes;

(h) impair the right of any Holder to receive payment of principal and interest on such Holder’s Notes on or after the due dates therefor or to institute suit for the enforcement of any payment on or with respect to such Holder’s Notes; or

(i) make any change in this Article 10 that requires each Holder’s consent or in the waiver provisions in Section 6.02 or Section 6.09.

Upon the written request of the Company, and upon the filing with the Trustee of evidence of the consent of Holders as aforesaid and subject to Section 10.05, the Trustee shall join with the Company in the execution of such supplemental indenture unless such supplemental indenture affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion, but shall not be obligated to, enter into such supplemental indenture.

Holders do not need under this Section 10.02 to approve the particular form of any proposed supplemental indenture. It shall be sufficient if such Holders approve the substance thereof. After any such supplemental indenture becomes effective, the Company shall give to the Holders (with a copy to the Trustee) a notice briefly describing such supplemental indenture. However, the failure to give such notice to all the Holders, or any defect in the notice, will not impair or affect the validity of the supplemental indenture.

Section 10.03. Effect of Supplemental Indentures. Upon the execution of any supplemental indenture pursuant to the provisions of this Article 10, this Indenture shall be and be deemed to be modified and amended in accordance therewith and the respective rights, limitation of rights, obligations, duties and immunities under this Indenture of the Trustee, the Company and the Holders shall thereafter be determined, exercised and enforced hereunder subject in all respects to such modifications and amendments and all the terms and conditions of any such supplemental indenture shall be and be deemed to be part of the terms and conditions of this Indenture for any and all purposes.

Section 10.04. Notation on Notes. Notes authenticated and delivered after the execution of any supplemental indenture pursuant to the provisions of this Article 10 may, at the Company’s expense, bear a notation in form reasonably acceptable to the Company and the Trustee as to any matter provided for in such supplemental indenture. If the Company or the Trustee shall so determine, new Notes so modified as to conform, in the opinion of the Trustee and the Board of Directors, to any modification of this Indenture contained in any such supplemental indenture may, at the Company’s expense, be prepared and executed by the Company, authenticated, upon receipt of a Company Order, by the Trustee (or an authenticating agent duly appointed by the Trustee pursuant to Section 17.10) and delivered in exchange for the Notes then outstanding, upon surrender of such Notes then outstanding.

57

Exhibit 4.1

Section 10.05. Evidence of Compliance of Supplemental Indenture to Be Furnished Trustee. In addition to the documents required by Section 17.05, the Trustee shall receive an Officer’s Certificate and an Opinion of Counsel as conclusive evidence that any supplemental indenture executed pursuant hereto complies with the requirements of this Article 10 and is permitted or authorized by this Indenture, and an Opinion of Counsel stating that such supplemental indenture is a valid and binding obligation of the Company, enforceable against the Company and any guarantors, as applicable, in accordance with its terms, subject to bankruptcy, insolvency, reorganization and other laws of general applicability relating to or affecting the enforcement of creditors’ rights and to general equity principles.

Article 11
Consolidation, Merger, Sale, Conveyance and Lease

Section 11.01. Company May Consolidate, Etc. on Certain Terms. Subject to the provisions of Section 11.02, the Company shall not consolidate with, merge with or into, or sell, convey, transfer or lease all or substantially all of its properties and assets to another Person (a “Business Combination Event”), unless:

(a) the resulting, surviving or transferee Person (the “Successor Entity”), if not the Company, shall be a Qualified Successor Entity organized and existing under the laws of the United States of America, any State thereof or the District of Columbia, and the Qualified Successor Entity (if not the Company) shall expressly assume, by supplemental indenture all of the obligations of the Company under the Notes and this Indenture; and

(b) immediately after giving effect to such Business Combination Event, no Default or Event of Default shall have occurred and be continuing under this Indenture.

For purposes of this Section 11.01, the sale, conveyance, transfer or lease of all or substantially all of the properties and assets of one or more Subsidiaries of the Company to another Person, which properties and assets, if held by the Company instead of such Subsidiaries, would constitute all or substantially all of the properties and assets of the Company on a consolidated basis, shall be deemed to be the sale, conveyance, transfer or lease of all or substantially all of the properties and assets of the Company to another Person.

Section 11.02. Successor Entity to Be Substituted. In case of any such consolidation, merger, sale, conveyance, transfer or lease and upon the assumption by the Successor Entity, by supplemental indenture, executed and delivered to the Trustee, of the due and punctual payment of the principal of and accrued and unpaid interest on all of the Notes, the due and punctual delivery or payment, as the case may be, of any consideration due upon conversion of the Notes and the due and punctual performance of all of the covenants and conditions of this Indenture to be performed by the Company, such Successor Entity (if not the Company) shall succeed to and, except in the case of a lease of all or substantially all of the Company’s properties and assets, shall be substituted for the Company, with the same effect as if it had been named herein as the party of the first part. Such Successor Entity thereupon may cause to be signed, and may issue either in its own name or in the name of the Company any or all of the Notes issuable hereunder

58

Exhibit 4.1

which theretofore shall not have been signed by the Company and delivered to the Trustee; and, upon the order of such Successor Entity instead of the Company and subject to all the terms, conditions and limitations in this Indenture prescribed, the Trustee shall authenticate and shall deliver, or cause to be authenticated and delivered, any Notes that previously shall have been signed and delivered by the Officers of the Company to the Trustee for authentication, and any Notes that such Successor Entity thereafter shall cause to be signed and delivered to the Trustee for that purpose. All the Notes so issued shall in all respects have the same legal rank and benefit under this Indenture as the Notes theretofore or thereafter issued in accordance with the terms of this Indenture as though all of such Notes had been issued at the date of the execution hereof. In the event of any such consolidation, merger, sale, conveyance or transfer (but not in the case of a lease), upon compliance with this Article 11 the Person named as the “Company” in the first paragraph of this Indenture (or any successor that shall thereafter have become such in the manner prescribed in this Article 11) may be dissolved, wound up and liquidated at any time thereafter and, except in the case of a lease, such Person shall be released from its liabilities as obligor and maker of the Notes and from its obligations under this Indenture and the Notes.

In case of any such consolidation, merger, sale, conveyance, transfer or lease, such changes in phraseology and form (but not in substance) may be made in the Notes thereafter to be issued as may be appropriate.

Section 11.03. Officer’s Certificate and Opinion of Counsel to Be Given to Trustee. If such Successor Company is not the Company, no such consolidation, merger, sale, conveyance, transfer or lease shall be effective unless the Trustee shall receive an Officer’s Certificate and an Opinion of Counsel as conclusive evidence that any such consolidation, merger, sale, conveyance, transfer or lease and any such assumption and, if a supplemental indenture is required in connection with such transaction, such supplemental indenture, complies with the provisions of this Article 11.

Article 12
Immunity of Incorporators, Stockholders, Officers and Directors

Section 12.01. Indenture and Notes Solely Corporate Obligations. No recourse for the payment of the principal of or accrued and unpaid interest on, or the payment or delivery of any Common Stock or cash due upon conversion of, any Note, nor for any claim based thereon or otherwise in respect thereof, and no recourse under or upon any obligation, covenant or agreement of the Company in this Indenture or in any supplemental indenture or in any Note, nor because of the creation of any indebtedness represented thereby, shall be had against any incorporator, stockholder, employee, agent, Officer or director or Subsidiary, as such, past, present or future, of the Company or of any successor corporation, either directly or through the Company or any successor corporation, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment or penalty or otherwise; it being expressly understood that all such liability is hereby expressly waived and released as a condition of, and as a consideration for, the execution of this Indenture and the issue of the Notes.

Exhibit 4.1

Article 13
[Intentionally Omitted]

Article 14
Conversion of Notes

Section 14.01. Conversion Privilege. (a) Subject to and upon compliance with the provisions of this Article 14, each Holder of a Note shall have the right, at such Holder’s option, to convert all or any portion (if the portion to be converted is a minimum of $1,000 principal amount or an integral multiple thereof) of such Note (i) subject to satisfaction of the conditions described in Section 14.01(b), at any time prior to the close of business on the Business Day immediately preceding October 1, 2028 under the circumstances and during the periods set forth in Section 14.01(b), and (ii) regardless of the conditions described in Section 14.01(b), on or after October 1, 2028 and prior to the close of business on the second Scheduled Trading Day immediately preceding the Maturity Date, in each case, based on an initial conversion rate of 10.6256 shares of Common Stock (subject to adjustment as provided in this Article 14, the “Conversion Rate”) per $1,000 principal amount of Notes (subject to, and in accordance with, the settlement provisions of Section 14.02, the “Conversion Obligation”).

(b) (i) Prior to the close of business on the Business Day immediately preceding October 1, 2028, a Holder may surrender all or any portion of its Notes for conversion at any time during the five Business Day period immediately after any ten consecutive Trading Day period (the “Measurement Period”) in which the Trading Price per $1,000 principal amount of Notes, as determined following a request by a Holder of Notes in accordance with this subsection (b)(i), for each Trading Day of the Measurement Period was less than 98% of the product of the Last Reported Sale Price of the Common Stock and the Conversion Rate on each such Trading Day. The Trading Prices shall be determined by the Bid Solicitation Agent pursuant to this subsection (b)(i) and the definition of Trading Price set forth in Section 1.01. At such time as the Company directs the Bid Solicitation Agent (if other than the Company) in writing to solicit bid quotations, the Company shall provide written notice to the Bid Solicitation Agent (if other than the Company) of the three independent nationally recognized securities dealers selected by the Company pursuant to the definition of Trading Price, along with appropriate contact information for each, and the Company shall direct those securities dealers to provide bids to the Bid Solicitation Agent in accordance with the definition of Trading Price. The Bid Solicitation Agent (if other than the Company) shall have no obligation to determine the Trading Price per $1,000 principal amount of Notes unless the Company has requested such determination in writing, and the Company shall have no obligation to make such request (or, if the Company is acting as Bid Solicitation Agent, the Company shall have no obligation to determine the Trading Price per $1,000 principal amount of Notes) unless a Holder or Holders of at least $2.0 million in aggregate principal amount of the Notes provides the Company with reasonable evidence that the Trading Price per $1,000 principal amount of Notes on any Trading Day would be less than 98% of the product of the Last Reported Sale Price of the Common Stock on such Trading Day and the Conversion Rate on such Trading Day, at which time the Company shall instruct the Bid Solicitation Agent (if other than the Company) to determine, or if the Company is acting as Bid Solicitation Agent, the Company shall determine, the Trading Price per $1,000 principal amount

60

Exhibit 4.1

of Notes beginning on the next Trading Day and on each successive Trading Day until the Trading Price per $1,000 principal amount of Notes is greater than or equal to 98% of the product of the Last Reported Sale Price of the Common Stock and the Conversion Rate. If (x) the Company is not acting as Bid Solicitation Agent, and the Company does not instruct the Bid Solicitation Agent in writing to determine the Trading Price per $1,000 principal amount of Notes when obligated as provided in the preceding sentence, or if the Company instructs the Bid Solicitation Agent in writing to obtain bids and the Bid Solicitation Agent fails to make such determination, or (y) the Company is acting as Bid Solicitation Agent and the Company fails to make such determination when obligated as provided in the preceding sentence, then, in either case, the Trading Price per $1,000 principal amount of Notes shall be deemed to be less than 98% of the product of the Last Reported Sale Price of the Common Stock and the Conversion Rate on each Trading Day of such failure. If the Trading Price condition set forth above has been met, the Company shall so notify the Holders, the Trustee and the Conversion Agent (if other than the Trustee) in writing. If, at any time after the Trading Price condition set forth above has been met, the Trading Price per $1,000 principal amount of Notes is greater than or equal to 98% of the product of the Last Reported Sale Price of the Common Stock and the Conversion Rate for such date, the Company shall so notify the Holders of the Notes, the Trustee and the Conversion Agent (if other than the Trustee) in writing.

(ii) If, prior to the close of business on the Business Day immediately preceding October 1, 2028, the Company elects to:

(A) issue to all or substantially all holders of the Common Stock any rights, options or warrants (other than in connection with a stockholder rights plan prior to separation of such rights from the Common Stock) entitling them, for a period of not more than 45 calendar days after the announcement date of such issuance, to subscribe for or purchase shares of the Common Stock at a price per share that is less than the average of the Last Reported Sale Prices of the Common Stock for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of such issuance; or

(B) distribute to all or substantially all holders of the Common Stock the Company’s assets, securities or rights to purchase securities of the Company, which distribution has a per share value, as determined by the Company in good faith and in a commercially reasonable manner, exceeding 10% of the Last Reported Sale Price of the Common Stock on the Trading Day immediately preceding the date of announcement for such distribution,

then, in either case, the Company shall notify all Holders of the Notes, the Trustee and the Conversion Agent (if other than the Trustee) in writing at least 55 Scheduled Trading Days prior to the Ex-Dividend Date for such issuance or distribution (or, if later in the case of any separation of rights issued pursuant to a stockholder rights plan, as soon as reasonably practicable after the Company becomes aware that such separation has occurred or will occur). Once the Company has given such notice, a Holder may surrender all or any portion of its Notes

61

Exhibit 4.1

for conversion at any time until the earlier of (1) the close of business on the Business Day immediately preceding the Ex-Dividend Date for such issuance or distribution and (2) the Company’s announcement that such issuance or distribution will not take place, in each case, even if the Notes are not otherwise convertible at such time.

Notwithstanding the foregoing, the Notes shall not become convertible on account of such issuance or distribution pursuant to this Section 14.01(b)(ii) (provided that the Company shall still be required to send notice of such issuance or distribution as described in the preceding paragraph) if each Holder participates, at the same time and on the same terms as holders of the Common Stock, and solely by virtue of being a Holder of a Note, in such issuance or distribution without having to convert such Notes held by such Holder as if such Holder held a number of shares of Common Stock equal to the product of (i) the Conversion Rate in effect on the Record Date for such issuance or distribution and (ii) the aggregate principal amount (expressed in thousands) of Notes held by such Holder on such date.

(iii) If a transaction or event that constitutes a Fundamental Change or a Make-Whole Fundamental Change occurs prior to the close of business on the Business Day immediately preceding October 1, 2028, regardless of whether a Holder has the right to require the Company to repurchase the Notes pursuant to Section 15.02, or if the Company is a party to a Share Exchange Event that occurs prior to the close of business on the Business Day immediately preceding October 1, 2028 (each such Fundamental Change, Make-Whole Fundamental Change or Share Exchange Event, a “Corporate Event”), then, in each case, all or any portion of a Holder’s Notes may be surrendered for conversion at any time from or after the effective date of such Corporate Event until the 35th Trading Day after such effective date or, if such Corporate Event also constitutes a Fundamental Change (other than an Exempted Fundamental Change), until the related Fundamental Change Repurchase Date. The Company shall notify Holders, the Trustee and the Conversion Agent (if other than the Trustee) of such Corporate Event and the related conversion right within two Business Days following the effective date of such Corporate Event. If the Company does not provide such notice by the second Business Day after such effective date, then the last day on which the Notes are convertible pursuant to this Section 14.01(b)(iii) as a result of such Corporate Event shall be extended by the number of Business Days from, and including, the second Business Day after such effective date to, but excluding, the date on which the Company provides the notice.

(iv) Prior to the close of business on the Business Day immediately preceding October 1, 2028, a Holder may surrender all or any portion of its Notes for conversion at any time during any calendar quarter commencing after the calendar quarter ending on June 30, 2024 (and only during such calendar quarter), if the Last Reported Sale Price of the Common Stock for at least 20 Trading Days (whether or not consecutive) during the period of 30 consecutive Trading Days ending on, and including, the last Trading Day of the immediately preceding calendar quarter is greater than or equal to 130% of the Conversion Price on each applicable Trading Day. Neither the Trustee nor the Conversion Agent shall have any duty to determine or verify the Company’s

62

Exhibit 4.1

determination of whether the conditions to conversion set forth in this Section 14.01(b)(iv) have been met.

(v) If the Company calls any or all of the Notes for redemption pursuant to Article 16, Holders may surrender for conversion Notes that have been so called (or deemed called in accordance with the last sentence of this clause (v)) for redemption at any time prior to the close of business on the Scheduled Trading Day immediately prior to the Redemption Date, even if such Notes are not otherwise convertible at such time. After that time, the right to convert such Notes on account of such Redemption Notice shall expire, unless the Company defaults in the payment of the Redemption Price, in which case a Holder of Notes called (or deemed called in accordance with the last sentence of this clause (v)) for redemption may convert all or any portion of such Notes called (or deemed called in accordance with the last sentence of this clause (v)) for redemption until the Redemption Price has been paid or duly provided for. If the Company elects to redeem less than all of the outstanding Notes pursuant to Article 16, and the Holder of any Note (or any owner of a beneficial interest in any Global Note) is reasonably not able to determine, before the close of business on the 52nd Scheduled Trading Day immediately before the relevant Redemption Date, whether such Note or beneficial interest, as applicable, is to be redeemed pursuant to such redemption, then, notwithstanding anything to the contrary in this Indenture or the Notes, such Holder or owner, as applicable, shall be entitled to convert such Note or beneficial interest, as applicable, at any time before the close of business on the Scheduled Trading Day immediately prior to such Redemption Date, unless the Company defaults in the payment of the Redemption Price, in which case such Holder or owner, as applicable, shall be entitled to convert such Note or beneficial interest, as applicable, until the Redemption Price has been paid or duly provided for, and in each case each such conversion shall be deemed to be of a Note called for redemption (including, without limitation, for purposes of Section 14.03).

Section 14.02. Conversion Procedure; Settlement Upon Conversion.

(a) Subject to this Section 14.02, Section 14.03(b) and Section 14.07(a), upon conversion of any Note, the Company shall pay or deliver, as the case may be, to the converting Holder, in respect of each $1,000 principal amount of Notes being converted, solely cash (“Cash Settlement”), or a combination of cash and shares of Common Stock, together with cash, if applicable, in lieu of delivering any fractional share of Common Stock in accordance with subsection (j) of this Section 14.02 (“Combination Settlement”), at its election, as set forth in this Section 14.02.

(i) All conversions of Notes called for redemption (or deemed called for redemption pursuant to Section 14.01(b)(v)) for which the relevant Conversion Date occurs during the related Redemption Period, and all conversions for which the relevant Conversion Date occurs on or after October 1, 2028, shall be settled using the same Settlement Method.

63

Exhibit 4.1

(ii) Except for any conversions referred to in Section 14.02(a)(i) for which the relevant Conversion Date occurs during a Redemption Period, and any conversions for which the relevant Conversion Date occurs on or after October 1, 2028, the Company shall use the same Settlement Method for all conversions with the same Conversion Date, but the Company shall not have any obligation to use the same Settlement Method with respect to conversions with different Conversion Dates.

(iii) If, in respect of any Conversion Date (or the period described in the fourth immediately succeeding set of parentheses, as the case may be), the Company elects to deliver a notice (the “Settlement Notice”) of the relevant Settlement Method in respect of such Conversion Date (or such period, as the case may be), the Company shall deliver such Settlement Notice in writing to converting Holders (with a written copy to the Trustee and the Conversion Agent (if other than the Trustee)) no later than the close of business on the Trading Day immediately following the relevant Conversion Date (or, in the case of (x) any conversions of Notes called for redemption (or deemed called for redemption pursuant to Section 14.01(b)(v)) for which the relevant Conversion Date occurs during a related Redemption Period, in the relevant Redemption Notice, or (y) any conversions of Notes for which the relevant Conversion Date occurs on or after October 1, 2028, no later than October 1, 2028). If the Company calls all or any Notes for redemption and the related Redemption Date is on or after October 1, 2028, then the Settlement Method that the Company elects to apply for conversions pursuant to Section 14.01(b)(v) with a Conversion Date occurring during the related Redemption Period must be the same Settlement Method that applies to all conversions with a Conversion Date that occurs on or after October 1, 2028. If the Company does not elect a Settlement Method with respect to a conversion prior to the deadline set forth in the second immediately preceding sentence, then the Company shall no longer have the right to elect a Settlement Method for such conversion and the Company shall be deemed to have elected the Default Settlement Method in respect of its Conversion Obligation. Such Settlement Notice shall specify the relevant Settlement Method and in the case of an election of Combination Settlement, the relevant Settlement Notice shall indicate the Specified Dollar Amount per $1,000 principal amount of Notes. If the Company delivers a Settlement Notice to Holders (with a written copy to the Trustee and the Conversion Agent (if other than the Trustee)) electing Combination Settlement in respect of its Conversion Obligation but does not indicate a Specified Dollar Amount per $1,000 principal amount of Notes in such Settlement Notice, the Specified Dollar Amount per $1,000 principal amount of Notes shall be deemed to be $1,000.

The Company shall have the right, from time to time prior to October 1, 2028, to change the Default Settlement Method to any Settlement Method that the Company is then permitted to elect, by sending notice to the Holders of the new Default Settlement Method (and, in such case, the Company will simultaneously send a copy of such notice to the Trustee and the Conversion Agent (if other than the Trustee)). In addition, by notice to Holders of the Notes, the Trustee and the Conversion Agent (if other than the Trustee), the Company may, prior to October 1, 2028, at its option, elect to (1) irrevocably fix the Settlement Method or (2) irrevocably eliminate any one or more (but

64

Exhibit 4.1

not all) Settlement Methods (including eliminating Combination Settlement Method with a particular Specified Dollar Amount or range of Specified Dollar Amounts); provided the Company is then otherwise permitted to elect the applicable Settlement Method(s) so irrevocably elected or the Settlement Method(s) remaining after such irrevocable elimination, as applicable, and provided further, that in no event may the Company elect (whether directly or by eliminating all other Settlement Methods) Combination Settlement with a Specified Dollar Amount that is less than $1,000 per $1,000 principal amount of Notes. If the Company makes such an irrevocable election, then such election will apply to all conversions of Notes with a Conversion Date that is on or after the date the Company sends such notice and the Company shall, if needed, simultaneously change the Default Settlement Method to a Settlement Method that is consistent with such irrevocable election. Notwithstanding the foregoing, no such irrevocable election or change of Default Settlement Method, as applicable, shall affect any Settlement Method theretofore elected (or deemed to be elected) with respect to any Note pursuant to this Section 14.02. For the avoidance of doubt, such an irrevocable election, if made, shall be effective without the need to amend this Indenture or the Notes, including pursuant to Section 10.01(g). However, the Company may nonetheless choose to execute such an amendment at the Company’s option.

If the Company changes the Default Settlement Method or makes an irrevocable election, as applicable, pursuant to the immediately preceding paragraph, then, promptly, but in any event within two Business Days, the Company shall either post the Default Settlement Method or such irrevocable election, as applicable, on its website or disclose the same in a current report on Form 8-K (or any successor form) that is filed with, or furnished to, the Commission.

(iv) The cash or combination of cash and shares of Common Stock, if any, in respect of any conversion of Notes (the “Settlement Amount”) shall be computed as follows:

(A) if the Company elects to satisfy its Conversion Obligation in respect of such conversion by Cash Settlement, the Company shall pay to the converting Holder in respect of each $1,000 principal amount of Notes being converted cash in an amount equal to the sum of the Daily Conversion Values for each of the 50 consecutive Trading Days during the related Observation Period; and

(B) if the Company elects (or is deemed to have elected) to satisfy its Conversion Obligation in respect of such conversion by Combination Settlement, the Company shall pay or deliver, as the case may be, in respect of each $1,000 principal amount of Notes being converted, a Settlement Amount equal to the sum of the Daily Settlement Amounts for each of the 50 consecutive Trading Days during the related Observation Period.

65

Exhibit 4.1

(v) The Daily Settlement Amounts (if applicable) and the Daily Conversion Values (if applicable) shall be determined by the Company as soon as reasonably practicable following the last day of the Observation Period. Following such determination of the Daily Settlement Amounts or the Daily Conversion Values, as the case may be, and the amount of cash payable in lieu of delivering any fractional share of Common Stock, the Company shall notify the Trustee and the Conversion Agent (if other than the Trustee) of the Daily Settlement Amounts or the Daily Conversion Values, as the case may be, and the amount of cash payable in lieu of delivering fractional shares of Common Stock. The Trustee and the Conversion Agent (if other than the Trustee) shall have no responsibility for any such determination.

(b) Subject to Section 14.02(e), before any Holder of a Note shall be entitled to convert a Note as set forth above, such Holder shall (i) in the case of a Global Note, comply with the procedures of the Depositary in effect at that time and, if required, pay to the Company funds equal to interest payable on the next Interest Payment Date as set forth in Section 14.02(h) and (ii) in the case of a Physical Note (1) complete, manually sign and deliver a medallion-stamped guaranteed irrevocable notice to the Conversion Agent as set forth in the Form of Notice of Conversion (a “Notice of Conversion”) at the office of the Conversion Agent and state in writing therein the principal amount of Notes to be converted and the name or names (with addresses) in which such Holder wishes the certificate or certificates for any shares of Common Stock to be delivered upon settlement of the Conversion Obligation to be registered, (2) surrender such Notes, duly endorsed to the Company or in blank (and accompanied by appropriate endorsement and transfer documents), at the office of the Conversion Agent, (3) if required, furnish appropriate endorsements and transfer documents and (4) if required, pay to the Company funds equal to interest payable on the next Interest Payment Date as set forth in Section 14.02(h). The Trustee (and if different, the Conversion Agent) shall notify the Company of any conversion pursuant to this Article 14 on the Conversion Date for such conversion. No Notice of Conversion with respect to any Notes may be surrendered by a Holder thereof if such Holder has also delivered a Fundamental Change Repurchase Notice to the Company in respect of such Notes and has not validly withdrawn such Fundamental Change Repurchase Notice in accordance with Section 15.03.

Subject to any procedures or requirements of the applicable Depositary in the case of any Global Note, if more than one Note shall be surrendered for conversion at one time by the same Holder, the Conversion Obligation with respect to such Notes shall be computed on the basis of the aggregate principal amount of the Notes (or specified portions thereof to the extent permitted thereby) so surrendered.

(c) A Note shall be deemed to have been converted immediately prior to the close of business on the date (the “Conversion Date”) that the Holder has complied with the requirements set forth in subsection (b) above. Except as set forth in ‎Section 14.03(b) and Section 14.07(a), the Company shall pay or deliver, as the case may be, the consideration due in respect of the Conversion Obligation on the second Business Day immediately following the last Trading Day of the relevant Observation Period. If any shares of Common Stock are due to a converting Holder, the Company shall issue and deliver (or otherwise cause to be issued and

66

Exhibit 4.1

delivered) to such Holder, or such Holder’s nominee or nominees, the full number of shares of Common Stock to which such Holder shall be entitled, in book-entry format through the Depositary, in satisfaction of the Company’s Conversion Obligation.

(d) In case any Note shall be surrendered for partial conversion, the Company shall execute and the Trustee shall authenticate and deliver to or upon the written order of the Holder of the Note so surrendered a new Note or Notes in Authorized Denominations in an aggregate principal amount equal to the unconverted portion of the surrendered Note, without payment of any service charge by the converting Holder but, if required by the Company or Trustee, with payment of a sum sufficient to cover any documentary, stamp or similar issue or transfer tax or similar governmental charge required by law or that may be imposed in connection therewith as a result of the name of the Holder of the new Notes issued upon such conversion being different from the name of the Holder of the old Notes surrendered for such conversion.

(e) If a Holder submits a Note for conversion, the Company shall pay any documentary, stamp or similar issue or transfer tax due on the issue or delivery of any shares of Common Stock upon conversion, unless the tax is due because the Holder requests such shares to be issued in a name other than the Holder’s name, in which case the Holder shall pay that tax. The Company may refuse to deliver the certificates (or book-entry evidence) representing the shares of Common Stock being issued in a name other than the Holder’s name until the Company receives a sum sufficient to pay any tax that is due by such Holder in accordance with the immediately preceding sentence.

(f) Except as provided in Section 14.04, no adjustment shall be made for dividends on any shares of Common Stock issued upon the conversion of any Note as provided in this Article 14.

(g) Upon the conversion of an interest in a Global Note, the Trustee, or the Custodian at the direction of the Trustee, shall make a notation on such Global Note as to the reduction in the principal amount represented thereby. The Company shall notify the Trustee in writing of any conversion of Notes effected through any Conversion Agent other than the Trustee.

(h) Upon conversion, a Holder shall not receive any separate cash payment for accrued and unpaid interest, if any, except as set forth below. The Company’s settlement of the full Conversion Obligation shall be deemed to satisfy in full its obligation to pay the principal amount of the Note and accrued and unpaid interest, if any, to, but not including, the relevant Conversion Date. As a result, accrued and unpaid interest, if any, to, but not including, the relevant Conversion Date shall be deemed to be paid in full rather than cancelled, extinguished or forfeited. Upon a conversion of Notes into a combination of cash and shares of Common Stock, accrued and unpaid interest will be deemed to be paid first out of the cash paid upon such conversion. Notwithstanding the foregoing, if Notes are converted after the close of business on a Regular Record Date, Holders of such Notes as of the close of business on such Regular Record Date will receive the full amount of interest payable on such Notes on the corresponding Interest Payment Date notwithstanding the conversion. Notes surrendered for conversion during the period from the close of business on any Regular Record Date to the open of business on the

67

Exhibit 4.1

immediately following Interest Payment Date must be accompanied by funds equal to the amount of interest payable on the Notes so converted; provided, however, that no such payment shall be required (1) for conversions following the Regular Record Date immediately preceding the Maturity Date; (2) if the Company has specified a Redemption Date that is after a Regular Record Date and on or prior to the Business Day immediately following the corresponding Interest Payment Date; (3) if the Company has specified a Fundamental Change Repurchase Date that is after a Regular Record Date and on or prior to the Business Day immediately following the corresponding Interest Payment Date; or (4) to the extent of any Defaulted Amounts, if any Defaulted Amounts exists at the time of conversion with respect to such Note. Therefore, for the avoidance of doubt, all Holders of record as of the close of business on the Regular Record Date immediately preceding the Maturity Date shall receive the full interest payment due on the Maturity Date in cash regardless of whether their Notes have been converted following such Regular Record Date, and the converting Holder shall not be required to make a corresponding payment.

(i) The Person in whose name any shares of Common Stock shall be issuable upon conversion shall be treated as a stockholder of record of such shares as of the close of business on the last Trading Day of the relevant Observation Period. Upon a conversion of Notes, such Person shall no longer be a Holder of such Notes surrendered for conversion.

(j) The Company shall not issue any fractional share of Common Stock upon conversion of the Notes and shall instead pay cash in lieu of delivering any fractional share of Common Stock issuable upon conversion based on the Daily VWAP for the last Trading Day of the relevant Observation Period. Subject to any procedures or requirements of the applicable Depositary in the case of any Global Note, for each Note surrendered for conversion, if the Company has elected Combination Settlement, the full number of shares that shall be issued upon conversion thereof shall be computed on the basis of the aggregate Daily Settlement Amounts for the relevant Observation Period and any fractional shares remaining after such computation shall be paid in cash.

Section 14.03. Increased Conversion Rate Applicable to Certain Notes Surrendered in Connection with Make-Whole Fundamental Changes or Redemption Notice. (a) If (x) the Effective Date of a Make-Whole Fundamental Change occurs prior to the Maturity Date or (y) the Company gives a Redemption Notice with respect to any or all of the Notes in accordance with Section 16.02 and, in each case, a Holder elects to convert any Note in connection with such Make-Whole Fundamental Change or Redemption Notice, as the case may be, then the Company shall, under the circumstances set forth below, increase the Conversion Rate for the Notes so surrendered for conversion by a number of additional shares of Common Stock (the “Additional Shares”), as set forth below. A conversion of Notes shall be deemed for these purposes to be “in connection with” such Make-Whole Fundamental Change if the relevant Notice of Conversion is received by the Conversion Agent from, and including, the Effective Date of such Make-Whole Fundamental Change up to, and including, the Business Day immediately prior to the related Fundamental Change Repurchase Date (or, in the case of an Exempted Fundamental Change or a Make-Whole Fundamental Change that would have been a Fundamental Change but for the proviso in clause (b) of the definition thereof, the 35th Trading Day immediately following the

68

Exhibit 4.1

Effective Date of such Make-Whole Fundamental Change) (such period, the “Make-Whole Fundamental Change Period”). A conversion of Notes called for redemption (or deemed called for redemption pursuant to Section 14.01(b)(v)) shall be deemed for these purposes to be “in connection with” a Redemption Notice if the relevant Conversion Date occurs during the related Redemption Period. For the avoidance of doubt, the Company shall increase the Conversion Rate in connection with a Redemption Notice only with respect to conversions of Notes called (or deemed called) for redemption, and not for Notes not called (or deemed called) for redemption. Accordingly, if the Company elects to redeem less than all of the outstanding Notes pursuant to Article 16, Holders of the Notes not called for redemption shall not be entitled to convert such Notes on account of the Redemption Notice and shall not be entitled to an increased Conversion Rate for conversions of such Notes on account of the Redemption Notice during the related Redemption Period if such Notes are otherwise convertible, except in the limited circumstances set forth under Section 14.01(b)(v).

(b) Upon surrender of Notes for conversion in connection with a Make-Whole Fundamental Change or Redemption Notice, the Company shall, at its option, satisfy the related Conversion Obligation by Cash Settlement or Combination Settlement in accordance with Section 14.02; provided, however, that if, at the effective time of a Make-Whole Fundamental Change described in clause (b) of the definition of Fundamental Change that constitutes a Share Exchange Event, the Reference Property of which is composed entirely of cash, for any conversion of Notes following the Effective Date of such Make-Whole Fundamental Change, the Conversion Obligation shall be calculated based solely on the Stock Price for the transaction and shall be deemed to be an amount of cash per $1,000 principal amount of converted Notes equal to the Conversion Rate (including any adjustment for Additional Shares), multiplied by such Stock Price. In such event, the Conversion Obligation shall be paid to Holders in cash on the second Business Day following the Conversion Date. The Company shall notify the Holders, the Trustee and the Conversion Agent (if other than the Trustee) in writing of the Effective Date of any Make-Whole Fundamental Change no later than five Business Days after such Effective Date.

(c) The number of Additional Shares, if any, by which the Conversion Rate shall be increased shall be determined by reference to the table below, based on the date on which the Make-Whole Fundamental Change occurs or becomes effective or the date of the Redemption Notice, as the case may be (in each case, the “Effective Date”), and the price (the “Stock Price”) paid (or deemed to be paid) per share of the Common Stock in the Make-Whole Fundamental Change or with respect to the Optional Redemption, as the case may be. If the holders of the Common Stock receive in exchange for their Common Stock only cash in a Make-Whole Fundamental Change described in clause (b) of the definition of Fundamental Change, the Stock Price shall be the cash amount paid per share. Otherwise, the Stock Price shall be the average of the Last Reported Sale Prices of the Common Stock over the five Trading Day period ending on, and including, the Trading Day immediately preceding the Effective Date of the Make-Whole Fundamental Change or the date the Company sends the Redemption Notice, as the case may be. The Company shall make appropriate adjustments to the Stock Price, in its good faith determination and in a commercially reasonable manner, to account for any adjustment to the Conversion Rate that becomes effective, or any event requiring an adjustment to the

69

Exhibit 4.1

Conversion Rate where the Ex-Dividend Date, Effective Date (as such term is used in Section 14.04) or expiration date of the event occurs during such five consecutive Trading Day period.

(d) The Stock Prices set forth in the column headings of the table below shall be adjusted as of any date on which the Conversion Rate of the Notes is otherwise adjusted. The adjusted Stock Prices shall equal the Stock Prices applicable immediately prior to such adjustment, multiplied by a fraction, the numerator of which is the Conversion Rate immediately prior to such adjustment giving rise to the Stock Price adjustment and the denominator of which is the Conversion Rate as so adjusted. The number of Additional Shares set forth in the table below shall be adjusted in the same manner and at the same time as the Conversion Rate as set forth in Section 14.04.

(e) The following table sets forth the number of Additional Shares of Common Stock by which the Conversion Rate shall be increased per $1,000 principal amount of Notes pursuant to this Section 14.03 for each Stock Price and Effective Date set forth below:

	Stock Price
Effective Date	$75.29	$80.00	$90.00	$94.11	$110.00	$122.35	$150.00	$200.00	$250.00	$300.00	$400.00	$550.00

The exact Stock Price and Effective Date may not be set forth in the table above, in which case:

(i) if the Stock Price is between two Stock Prices in the table above or the Effective Date is between two Effective Dates in the table, the number of Additional Shares by which the Conversion Rate will be increased shall be determined by a straight-line interpolation between the number of Additional Shares set forth for the higher and lower Stock Prices and the earlier and later Effective Dates, as applicable, based on a 365-day year;

(ii) if the Stock Price is greater than $550.00 per share (subject to adjustment in the same manner as the Stock Prices set forth in the column headings of the table above pursuant to subsection (d) above), no Additional Shares shall be added to the Conversion Rate; and

(iii) if the Stock Price is less than $75.29 per share (subject to adjustment in the same manner as the Stock Prices set forth in the column headings of the table above pursuant to subsection (d) above), no Additional Shares shall be added to the Conversion Rate.

70

Exhibit 4.1

Notwithstanding the foregoing, in no event shall the Conversion Rate per $1,000 principal amount of Notes exceed 13.2819 shares of Common Stock, subject to adjustment in the same manner as the Conversion Rate pursuant to Section 14.04.

(f) Nothing in this Section 14.03 shall prevent an adjustment to the Conversion Rate pursuant to Section 14.04 in respect of a Make-Whole Fundamental Change.

Section 14.04. Adjustment of Conversion Rate. The Conversion Rate shall be adjusted from time to time by the Company if any of the following events occurs, except that the Company shall not make any adjustments to the Conversion Rate if each Holder of the Notes participates (other than in the case of (x) a share split or share combination or (y) a tender or exchange offer), at the same time and upon the same terms as holders of the Common Stock and solely as a result of holding the Notes, in any of the transactions described in this Section 14.04, without having to convert such Holder’s Notes, as if such Holder held a number of shares of Common Stock equal to the Conversion Rate, multiplied by the principal amount (expressed in thousands) of Notes held by such Holder.

(a) If the Company exclusively issues shares of Common Stock as a dividend or distribution on all or substantially all outstanding shares of the Common Stock, or if the Company effects a share split or share combination, the Conversion Rate shall be adjusted based on the following formula:

 

where,

CR0 = the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date of such dividend or distribution, or immediately prior to the open of business on the Effective Date of such share split or share combination, as applicable;

CR' = the Conversion Rate in effect immediately after the open of business on such Ex-Dividend Date or Effective Date;

OS0 = the number of shares of Common Stock outstanding immediately prior to the open of business on such Ex-Dividend Date or Effective Date (before giving effect to such dividend, distribution, split or combination); and

OS' = the number of shares of Common Stock outstanding immediately after giving effect to such dividend, distribution, share split or share combination.

Any adjustment made under this Section 14.04(a) shall become effective immediately after the open of business on the Ex-Dividend Date for such dividend or distribution, or immediately after the open of business on the Effective Date for such share split or share combination, as

71

Exhibit 4.1

applicable. If any dividend or distribution of the type described in this Section 14.04(a) is declared but not so paid or made, the Conversion Rate shall be immediately readjusted, effective as of the date the Board of Directors determines not to pay such dividend or distribution, to the Conversion Rate that would then be in effect if such dividend or distribution had not been declared.

(b) If the Company issues to all or substantially all holders of the Common Stock any rights, options or warrants (other than in connection with a stockholders’ rights plan) entitling them, for a period of not more than 45 calendar days after the announcement date of such issuance, to subscribe for or purchase shares of the Common Stock at a price per share that is less than the average of the Last Reported Sale Prices of the Common Stock for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of such issuance, the Conversion Rate shall be increased based on the following formula:

 

where,

CR0 = the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such issuance;

CR' = the Conversion Rate in effect immediately after the open of business on such Ex-Dividend Date;

OS0 = the number of shares of Common Stock outstanding immediately prior to the open of business on such Ex-Dividend Date;

X = the total number of shares of Common Stock issuable pursuant to such rights, options or warrants; and

Y = the number of shares of Common Stock equal to the aggregate price payable to exercise such rights, options or warrants, divided by the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of the issuance of such rights, options or warrants.

Any increase made under this Section 14.04(b) shall be made successively whenever any such rights, options or warrants are issued and shall become effective immediately after the open of business on the Ex-Dividend Date for such issuance. To the extent that shares of the Common Stock are not delivered after the expiration of such rights, options or warrants, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect had the increase with respect to the issuance of such rights, options or warrants been made on the basis of delivery of only the number of shares of Common Stock actually delivered. If such rights, options or

72

Exhibit 4.1

warrants are not so issued, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect if such Ex-Dividend Date for such issuance had not occurred.

For purposes of this Section 14.04(b) and for the purpose of Section 14.01(b)(ii)(A), in determining whether any rights, options or warrants entitle the holders to subscribe for or purchase shares of the Common Stock at less than such average of the Last Reported Sale Prices of the Common Stock for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement for such issuance, and in determining the aggregate offering price of such shares of Common Stock, there shall be taken into account any consideration received by the Company for such rights, options or warrants and any amount payable on exercise or conversion thereof, the value of such consideration, if other than cash, to be determined by the Company in good faith and in a commercially reasonable manner.

(c) If the Company distributes shares of its Capital Stock, evidences of its indebtedness, other assets or property of the Company or rights, options or warrants to acquire its Capital Stock or other securities, to all or substantially all holders of the Common Stock, excluding (i) dividends, distributions or issuances as to which an adjustment was effected (or would have been effected but for the 1% Exception) pursuant to Section 14.04(a) or Section 14.04(b), (ii) dividends or distributions paid exclusively in cash as to which the provisions set forth in Section 14.04(d) shall apply, (iii) rights issued pursuant to a rights plan, except to the extent set forth in Section 14.11, (iv) any distributions of Reference Property in exchange for the Common Stock in connection with a Share Exchange Event, (v) tender offers and exchange offers as to which an adjustment is effected (or would have been effected but for the 1% Exception) pursuant to Section 14.04(e), and (vi) Spin-Offs as to which the provisions set forth below in this Section 14.04(c) shall apply (any of such shares of Capital Stock, evidences of indebtedness, other assets or property or rights, options or warrants to acquire Capital Stock or other securities, the “Distributed Property”), then the Conversion Rate shall be increased based on the following formula:

 

where,

CR0 = the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such distribution;

CR' = the Conversion Rate in effect immediately after the open of business on such Ex-Dividend Date;

SP0 = the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Ex-Dividend Date for such distribution; and

73

Exhibit 4.1

FMV = the fair market value (as determined by the Company in good faith and in a commercially reasonable manner) of the Distributed Property with respect to each outstanding share of the Common Stock on the Ex-Dividend Date for such distribution.

Any increase made under the portion of this Section 14.04(c) above shall become effective immediately after the open of business on the Ex-Dividend Date for such distribution. If such distribution is not so paid or made, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect if such distribution had not been declared. Notwithstanding the foregoing, if “FMV” (as defined above) is equal to or greater than “SP0” (as defined above), in lieu of the foregoing increase, each Holder of a Note shall receive, in respect of each $1,000 principal amount thereof, at the same time and upon the same terms as holders of the Common Stock receive the Distributed Property, the amount and kind of Distributed Property such Holder would have received if such Holder owned a number of shares of Common Stock equal to the Conversion Rate in effect on the Ex-Dividend Date for the distribution. If the Company determines the “FMV” (as defined above) of any distribution for purposes of this Section 14.04(c) by reference to the actual or when-issued trading market for any securities, it shall in doing so consider the prices in such market over the same period used in computing the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Ex-Dividend Date for such distribution.

With respect to an adjustment pursuant to this Section 14.04(c) where there has been a payment of a dividend or other distribution on the Common Stock of shares of Capital Stock of any class or series, or similar equity interest, of or relating to a Subsidiary or other business unit of the Company, that are, or, when issued, will be, listed or admitted for trading on a U.S. national securities exchange (a “Spin-Off”), the Conversion Rate shall be increased based on the following formula:

 

where,

CR0 = the Conversion Rate in effect immediately prior to the end of the Valuation Period;

CR' = the Conversion Rate in effect immediately after the end of the Valuation Period;

FMV0 = the average of the Last Reported Sale Prices of the Capital Stock or similar equity interest distributed to holders of the Common Stock applicable to one share of the Common Stock (determined by reference to the definitions of Last Reported Sale Price, Trading Day and Market Disruption Event as set forth in Section 1.01 as if references therein to Common Stock were to such Capital Stock

74

Exhibit 4.1

or similar equity interest) over the first 10 consecutive Trading Day period after, and including, the Ex-Dividend Date of the Spin-Off (the “Valuation Period”); and

MP0 = the average of the Last Reported Sale Prices of the Common Stock over the Valuation Period.

The increase to the Conversion Rate under the preceding paragraph shall occur at the close of business on the last Trading Day of the Valuation Period; provided that, in respect of any conversion of Notes, for any Trading Day that falls within the relevant Observation Period for such conversion and within the Valuation Period, references to “10” in the preceding paragraph shall be deemed to be replaced with such lesser number of Trading Days as have elapsed between the Ex-Dividend Date of such Spin-Off and such Trading Day in determining the Conversion Rate as of such Trading Day. In addition, if the Ex-Dividend Date of the Spin-Off is after the 10th Trading Day immediately preceding, and including, the end of any Observation Period in respect of a conversion of Notes, references to “10” or “10th” in the preceding paragraph and this paragraph shall be deemed to be replaced, solely in respect of that conversion of Notes, with such lesser number of Trading Days as have elapsed from, and including, the Ex-Dividend Date for the Spin-Off to, and including, the last Trading Day of such Observation Period.

For purposes of this Section 14.04(c) (and subject in all respect to Section 14.10), rights, options or warrants distributed by the Company to all holders of the Common Stock entitling them to subscribe for or purchase shares of the Company’s Capital Stock, including Common Stock (either initially or under certain circumstances), which rights, options or warrants, until the occurrence of a specified event or events (“Trigger Event”): (i) are deemed to be transferred with such shares of the Common Stock; (ii) are not exercisable; and (iii) are also issued in respect of future issuances of the Common Stock, shall be deemed not to have been distributed for purposes of this Section 14.04(c) (and no adjustment to the Conversion Rate under this Section 14.04(c) will be required) until the occurrence of the earliest Trigger Event, whereupon such rights, options or warrants shall be deemed to have been distributed and an appropriate adjustment (if any is required) to the Conversion Rate shall be made under this Section 14.04(c). If any such right, option or warrant, including any such existing rights, options or warrants distributed prior to the date of this Indenture, are subject to events, upon the occurrence of which such rights, options or warrants become exercisable to purchase different securities, evidences of indebtedness or other assets, then the date of the occurrence of any and each such event shall be deemed to be the date of distribution and Ex-Dividend Date with respect to new rights, options or warrants with such rights (in which case the existing rights, options or warrants shall be deemed to terminate and expire on such date without exercise by any of the holders thereof). In addition, in the event of any distribution (or deemed distribution) of rights, options or warrants, or any Trigger Event or other event (of the type described in the immediately preceding sentence) with respect thereto that was counted for purposes of calculating a distribution amount for which an adjustment to the Conversion Rate under this Section 14.04(c) was made, (1) in the case of any such rights, options or warrants that shall all have been redeemed or purchased without exercise by any holders thereof, upon such final redemption or purchase (x) the

75

Exhibit 4.1

Conversion Rate shall be readjusted as if such rights, options or warrants had not been issued and (y) the Conversion Rate shall then again be readjusted to give effect to such distribution, deemed distribution or Trigger Event, as the case may be, as though it were a cash distribution, equal to the per share redemption or purchase price received by a holder or holders of Common Stock with respect to such rights, options or warrants (assuming such holder had retained such rights, options or warrants), made to all holders of Common Stock as of the date of such redemption or purchase, and (2) in the case of such rights, options or warrants that shall have expired or been terminated without exercise by any holders thereof, the Conversion Rate shall be readjusted as if such rights, options and warrants had not been issued.

For purposes of Section 14.04(a), Section 14.04(b) and this Section 14.04(c), if any dividend or distribution to which this Section 14.04(c) is applicable also includes one or both of:

(A) a dividend or distribution of shares of Common Stock to which Section 14.04(a) is applicable (the “Clause A Distribution”); or

(B) a dividend or distribution of rights, options or warrants to which Section 14.04(b) is applicable (the “Clause B Distribution”),

then, in either case, (1) such dividend or distribution, other than the Clause A Distribution and the Clause B Distribution, shall be deemed to be a dividend or distribution to which this Section 14.04(c) is applicable (the “Clause C Distribution”) and any Conversion Rate adjustment required by this Section 14.04(c) with respect to such Clause C Distribution shall then be made, and (2) the Clause A Distribution and Clause B Distribution shall be deemed to immediately follow the Clause C Distribution and any Conversion Rate adjustment required by Section 14.04(a) and Section 14.04(b) with respect thereto shall then be made, except that, if determined by the Company (I) the “Ex-Dividend Date” of the Clause A Distribution and the Clause B Distribution shall be deemed to be the Ex-Dividend Date of the Clause C Distribution and (II) any shares of Common Stock included in the Clause A Distribution or Clause B Distribution shall be deemed not to be “outstanding immediately prior to the open of business on such Ex-Dividend Date or Effective Date” within the meaning of Section 14.04(a) or “outstanding immediately prior to the open of business on such Ex-Dividend Date” within the meaning of Section 14.04(b).

(d) If any cash dividend or distribution is made to all or substantially all holders of the Common Stock, the Conversion Rate shall be adjusted based on the following formula:

 

where,

CR0 = the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such dividend or distribution;

76

Exhibit 4.1

CR' = the Conversion Rate in effect immediately after the open of business on the Ex-Dividend Date for such dividend or distribution;

SP0 = the Last Reported Sale Price of the Common Stock on the Trading Day immediately preceding the Ex-Dividend Date for such dividend or distribution; and

C = the amount in cash per share the Company distributes to all or substantially all holders of the Common Stock.

Any increase pursuant to this Section 14.04(d) shall become effective immediately after the open of business on the Ex-Dividend Date for such dividend or distribution. If such dividend or distribution is not so paid, the Conversion Rate shall be decreased, effective as of the date the Board of Directors determines not to make or pay such dividend or distribution, to be the Conversion Rate that would then be in effect if such dividend or distribution had not been declared. Notwithstanding the foregoing, if “C” (as defined above) is equal to or greater than “SP0” (as defined above), then, in lieu of the foregoing increase, each Holder of a Note shall receive, for each $1,000 principal amount of Notes, at the same time and upon the same terms as holders of shares of the Common Stock, the amount of cash that such Holder would have received if such Holder owned a number of shares of Common Stock equal to the Conversion Rate on the Ex-Dividend Date for such cash dividend or distribution.

(e) If the Company or any of its Subsidiaries makes a payment in respect of a tender or exchange offer for the Common Stock (other than an odd-lot tender offer pursuant to Rule 13e-4(h)(5) under the Exchange Act or any successor rule), to the extent that the cash and value (determined as of the date of such tender or exchange offer expires by the Company in good faith and in a commercially reasonable manner) of any other consideration included in the payment per share of the Common Stock exceeds the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period commencing on, and including, the Trading Day next succeeding the last date on which tenders or exchanges may be made pursuant to such tender or exchange offer, the Conversion Rate shall be increased based on the following formula:

 

where,

CR0 = the Conversion Rate in effect immediately prior to the close of business on the 10th Trading Day immediately following, and including, the Trading Day next succeeding the date such tender or exchange offer expires;

CR' = the Conversion Rate in effect immediately after the close of business on the 10th Trading Day immediately following, and including, the Trading Day next succeeding the date such tender or exchange offer expires;

77

Exhibit 4.1

AC = the aggregate value of all cash and any other consideration (determined as of the date such tender or exchange offer expires by the Company in good faith and in a commercially reasonable manner) paid or payable for shares of Common Stock purchased in such tender or exchange offer;

OS0 = the number of shares of Common Stock outstanding immediately prior to the date such tender or exchange offer expires (prior to giving effect to the purchase of all shares of Common Stock accepted for purchase or exchange in such tender or exchange offer);

OS' = the number of shares of Common Stock outstanding immediately after the date such tender or exchange offer expires (after giving effect to the purchase of all shares of Common Stock accepted for purchase or exchange in such tender or exchange offer); and

SP' = the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period commencing on, and including, the Trading Day next succeeding the date such tender or exchange offer expires.

The increase to the Conversion Rate under this Section 14.04(e) shall occur at the close of business on the 10th Trading Day immediately following, and including, the Trading Day next succeeding the date such tender or exchange offer expires; provided that, in respect of any conversion of Notes, for any Trading Day that falls within the relevant Observation Period for such conversion and within the 10 Trading Days immediately following, and including, the Trading Day next succeeding the expiration date of any tender or exchange offer, references to “10” or “10th” in the preceding paragraph shall be deemed replaced with such lesser number of Trading Days as have elapsed between the expiration date of such tender or exchange offer and such Trading Day in determining the Conversion Rate as of such Trading Day. In addition, if the Trading Day next succeeding the date such tender or exchange offer expires is after the 10th Trading Day immediately preceding, and including, the end of any Observation Period in respect of a conversion of Notes, references to “10” or “10th” in the preceding paragraph and this paragraph shall be deemed to be replaced, solely in respect of that conversion of Notes, with such lesser number of Trading Days as have elapsed from, and including, the Trading Day next succeeding the date such tender or exchange offer expires to, and including, the last Trading Day of such Observation Period.

(f) Notwithstanding this Section 14.04 or any other provision of this Indenture or the Notes, if (i) a Conversion Rate adjustment for any dividend or distribution becomes effective on any Ex-Dividend Date pursuant to the provisions in this Section 14.04, (ii) a Note is to be converted pursuant to Combination Settlement, (iii) any Trading Day in the Observation Period for such conversion occurs on or after such Ex-Dividend Date and on or before the related Record Date, (iv) the consideration due in respect of such Trading Day includes any whole or fractional shares of Common Stock based on a Conversion Rate that is adjusted for such dividend or distribution, and (v) such shares of Common Stock would otherwise be entitled to participate in such dividend or distribution, then the Conversion Rate adjustment relating to such

78

Exhibit 4.1

Ex-Dividend Date shall be made for such conversion in respect of such Trading Day, provided that the shares of Common Stock issuable with respect to such Trading Day based on such adjusted Conversion Rate shall not be entitled to participate in such dividend or distribution.

(g) Except as stated herein, the Company shall not adjust the Conversion Rate for the issuance of shares of the Common Stock or any securities convertible into or exchangeable for shares of the Common Stock or the right to purchase shares of the Common Stock or such convertible or exchangeable securities.

(h) In addition to those adjustments required by clauses (a), (b), (c), (d) and (e) of this Section 14.04, and to the extent permitted by applicable law and subject to the applicable rules of any exchange on which any of the Company’s securities are then listed, the Company from time to time may increase the Conversion Rate by any amount for a period of at least 20 Business Days if the Board of Directors determines that such increase would be in the Company’s best interest. In addition, to the extent permitted by applicable law and subject to the applicable rules of any exchange on which any of the Company’s securities are then listed, the Company may (but is not required to) increase the Conversion Rate to avoid or diminish any income tax to holders of Common Stock or rights to purchase Common Stock in connection with a dividend or distribution of shares of Common Stock (or rights to acquire shares of Common Stock) or similar event. Whenever the Conversion Rate is increased pursuant to either of the preceding two sentences, the Company shall deliver to the Holder of each Note a notice of the increase at least 15 days prior to the date the increased Conversion Rate takes effect, and such notice shall state the increased Conversion Rate and the period during which it will be in effect.

(i) Notwithstanding anything to the contrary in this Article 14, the Conversion Rate shall not be adjusted:

(i) upon the issuance of any shares of Common Stock pursuant to any present or future plan providing for the reinvestment of dividends or interest payable on the Company’s securities and the investment of additional optional amounts in shares of Common Stock under any plan;

(ii) upon the issuance of any shares of Common Stock or options or rights to purchase those shares pursuant to any present or future employee, director or consultant benefit plan or program of or assumed by the Company or any of the Company’s Subsidiaries;

(iii) upon the issuance of any shares of the Common Stock pursuant to any option, warrant, right or exercisable, exchangeable or convertible security not described in clause (ii) of this subsection and outstanding as of the date the Notes were first issued;

(iv) upon the repurchase of any shares of Common Stock pursuant to an open market share repurchase program or other buy-back transaction that is not a tender offer or exchange offer of the nature described under Section 14.04(e);

(v) solely for a change in the par value of the Common Stock; or

79

Exhibit 4.1

(vi) for accrued and unpaid interest, if any.

(j) All calculations and other determinations under this Article 14 shall be made by the Company and shall be made to the nearest one-ten thousandth (1/10,000th) of a share.

(k) The Company shall not be required to make an adjustment to the Conversion Rate unless the adjustment would require a change of at least 1% in the Conversion Rate; provided that the Company shall carry forward any adjustments that are less than 1% of the Conversion Rate and make such carried-forward adjustments, regardless of whether the aggregate adjustment is at least 1%, (i) on the effective date for any Make-Whole Fundamental Change and/or Fundamental Change, (ii) prior to the close of business on the Conversion Date for any Note in respect of any conversion following a replacement of the Common Stock by Reference Property consisting solely of cash, (iii) prior to the open of business on each Trading Day of any Observation Period in respect of the conversion of any Note, (iv) on the date the Company sends a Redemption Notice for all or any Notes; (v) on the date on which all such deferred adjustments would result in an aggregate change to the Conversion Rate of at least 1% and (vi) on October 1, 2028.

(l) Whenever the Conversion Rate is adjusted as herein provided, the Company shall promptly file with the Trustee (and the Conversion Agent if not the Trustee) an Officer’s Certificate setting forth the Conversion Rate after such adjustment and setting forth a brief statement of the facts requiring such adjustment. Unless and until a Responsible Officer of the Trustee shall have received such Officer’s Certificate, the Trustee shall not be deemed to have knowledge of any adjustment of the Conversion Rate and may assume without inquiry that the last Conversion Rate of which it has knowledge is still in effect. Promptly after delivery of such certificate, the Company shall prepare a notice of such adjustment of the Conversion Rate setting forth the adjusted Conversion Rate and the date on which each adjustment becomes effective and shall deliver such notice of such adjustment of the Conversion Rate to each Holder. Failure to deliver such notice shall not affect the legality or validity of any such adjustment.

(m) For purposes of this Section 14.04, the number of shares of Common Stock at any time outstanding shall not include shares of Common Stock held in the treasury of the Company so long as the Company does not pay any dividend or make any distribution on shares of Common Stock held in the treasury of the Company, but shall include shares of Common Stock issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock.

Section 14.05. Adjustments of Prices. Whenever any provision of this Indenture requires the Company to calculate the Last Reported Sale Prices, the Daily VWAPs, the Daily Conversion Values or the Daily Settlement Amounts over a span of multiple days (including, without limitation, an Observation Period and the period for determining the Stock Price for purposes of a Make-Whole Fundamental Change or Optional Redemption), the Company shall make appropriate adjustments to each in good faith and in a commercially reasonable manner to account for any adjustment to the Conversion Rate that becomes effective, or any event requiring an adjustment to the Conversion Rate where the Ex-Dividend Date, Effective Date or expiration date, as the case may be, of the event occurs, at any time during the period when the Last

80

Exhibit 4.1

Reported Sale Prices, the Daily VWAPs, the Daily Conversion Values or the Daily Settlement Amounts are to be calculated.

Section 14.06. Shares to Be Fully Paid. The Company shall at all times reserve, free from preemptive rights, out of its authorized but unissued shares or shares held in treasury, a number of shares of Common Stock equal to the product of (i) the aggregate principal amount (expressed in thousands) of all then-outstanding Notes, divided by $1,000; and (ii) the Conversion Rate then in effect (assuming, for these purposes, that the Conversion Rate is increased by the maximum amount which the Conversion Rate may be increased pursuant to Section 14.03) to provide for conversion of the Notes from time to time as such Notes are presented for conversion.

Section 14.07. Effect of Recapitalizations, Reclassifications and Changes of the Common Stock.

(a) In the case of:

(i) any recapitalization, reclassification or change of the Common Stock (other than changes resulting from a subdivision or combination),

(ii) any consolidation, merger, combination or similar transaction involving the Company,

(iii) any sale, lease or other transfer to a third party of the consolidated assets of the Company and the Company’s Subsidiaries substantially as an entirety or

(iv) any statutory share exchange,

in each case, as a result of which the Common Stock would be converted into, or exchanged for, stock, other securities, other property or assets (including cash or any combination thereof) (any such event, a “Share Exchange Event”), then, at and after the effective time of such Share Exchange Event, the right to convert each $1,000 principal amount of Notes shall be changed into a right to convert such principal amount of Notes into the kind and amount of shares of stock, other securities or other property or assets (including cash or any combination thereof) that a holder of a number of shares of Common Stock equal to the Conversion Rate immediately prior to such Share Exchange Event would have owned or been entitled to receive (the “Reference Property,” with each “unit of Reference Property” meaning the kind and amount of Reference Property that a holder of one share of Common Stock is entitled to receive) upon such Share Exchange Event and, prior to or at the effective time of such Share Exchange Event, the Company or the successor or purchasing Person, as the case may be, shall execute with the Trustee a supplemental indenture permitted under Section 10.01(g) providing for such change in the right to convert each $1,000 principal amount of Notes; provided, however, that at and after the effective time of the Share Exchange Event (A) the Company shall continue to have the right to determine the form of consideration to be paid or delivered, as the case may be, upon conversion of Notes in accordance with Section 14.02 and (B) (I) any amount payable in cash upon conversion of the Notes in accordance with Section 14.02 shall continue to be payable in

81

Exhibit 4.1

cash, (II) any shares of Common Stock that the Company would have been required to deliver upon conversion of the Notes in accordance with Section 14.02 shall instead be deliverable in the amount and type of Reference Property that a holder of that number of shares of Common Stock would have been entitled to receive in such Share Exchange Event and (III) the Daily VWAP and the Last Reported Sale Price (including, without limitation, for purposes of Article 16) shall be calculated based on the value (as determined by, or in the manner proscribed by, the Board of Directors) of a unit of Reference Property.

If the Share Exchange Event causes the Common Stock to be converted into, or exchanged for, the right to receive more than a single type of consideration (determined based in part upon any form of stockholder election), then (i) the Reference Property into which the Notes will be convertible shall be deemed to be the types and amounts of consideration actually received by the holders of Common Stock, and (ii) the unit of Reference Property for purposes of the immediately preceding paragraph shall refer to the weighted average of the consideration referred to in clause (i) attributable to one share of Common Stock. If the holders of the Common Stock receive only cash in such Share Exchange Event, then for all conversions for which the relevant Conversion Date occurs after the effective date of such Share Exchange Event (A) the consideration due upon conversion of each $1,000 principal amount of Notes shall be solely cash in an amount equal to the Conversion Rate in effect on the Conversion Date (as may be increased by any Additional Shares pursuant to Section 14.03), multiplied by the price paid per share of Common Stock in such Share Exchange Event and (B) the Company shall satisfy the Conversion Obligation by paying cash to converting Holders on the second Business Day immediately following the relevant Conversion Date. The Company shall notify Holders, the Trustee and the Conversion Agent (if other than the Trustee) of such weighted average as soon as practicable after such determination is made.

Such supplemental indenture described in the second immediately preceding paragraph shall provide for anti-dilution and other adjustments that shall be as nearly equivalent as is possible to the adjustments provided for in this Article 14. If, in the case of any Share Exchange Event, the Reference Property includes shares of stock, securities or other property or assets (including cash or any combination thereof) of a Person other than the Company or the successor or purchasing entity, as the case may be, in such Share Exchange Event, then such supplemental indenture shall also be executed by such other Person, if an affiliate of the Company or the successor or purchasing entity, and shall contain such additional provisions to protect the interests of the Holders of the Notes as the Board of Directors shall consider in good faith necessary by reason of the foregoing, including the provisions providing for the purchase rights set forth in Article 15.

(b) When the Company executes a supplemental indenture pursuant to subsection (a) of this Section 14.07, the Company shall promptly file with the Trustee an Officer’s Certificate briefly stating the reasons therefor, the kind or amount of cash, securities or property or asset that will comprise a unit of Reference Property after any such Share Exchange Event, any adjustment to be made with respect thereto and that all conditions precedent have been complied with, and shall promptly deliver notice thereof to all Holders. The Company shall cause notice of the execution of such supplemental indenture to be delivered to each Holder within 20 days after

82

Exhibit 4.1

execution thereof. Failure to deliver such notice shall not affect the legality or validity of such supplemental indenture.

(c) The Company shall not become a party to any Share Exchange Event unless its terms are consistent with this Section 14.07. None of the foregoing provisions shall affect the right of a holder of Notes to convert its Notes, as set forth in Section 14.01 and Section 14.02 prior to the effective date of such Share Exchange Event.

(d) The above provisions of this Section shall similarly apply to successive Share Exchange Events.

Section 14.08. Certain Covenants. (a) The Company covenants that all shares of Common Stock issued upon conversion of Notes will be fully paid and non-assessable by the Company and free from all taxes, liens and charges with respect to the issue thereof.

(b) The Company further covenants that, if any shares of Common Stock to be provided for the purpose of conversion of Notes hereunder require registration with or approval of any governmental authority under any federal or state law before such shares of Common Stock may be validly issued upon conversion, the Company will, to the extent then permitted by the rules and interpretations of the Commission, secure such registration or approval, as the case may be.

(c) The Company further covenants that if at any time the Common Stock shall be listed on any national securities exchange or automated quotation system the Company will use its reasonable best efforts to list and keep listed, so long as the Common Stock shall be so listed on such exchange or automated quotation system, any Common Stock issuable upon conversion of the Notes.

Section 14.09. Responsibility of Trustee. The Trustee and any other Conversion Agent shall not at any time be under any duty or responsibility to any Holder to determine the Conversion Rate (or any adjustment thereto) or whether any facts exist that may require any adjustment (including any increase) of the Conversion Rate, or with respect to the nature or extent or calculation of any such adjustment when made, or with respect to the method employed, or herein or in any supplemental indenture provided to be employed, in making the same. The Trustee and any other Conversion Agent shall not be accountable with respect to the validity or value (or the kind or amount) of any shares of Common Stock, or of any securities, property or cash that may at any time be issued or delivered upon the conversion of any Note; and the Trustee and any other Conversion Agent make no representations with respect thereto. Neither the Trustee nor any Conversion Agent shall be responsible for any failure of the Company to issue, transfer or deliver any shares of Common Stock or stock certificates or other securities or property or cash upon the surrender of any Note for the purpose of conversion or to comply with any of the duties, responsibilities or covenants of the Company contained in this Article. Without limiting the generality of the foregoing, neither the Trustee nor any Conversion Agent shall be under any responsibility to determine the correctness of any provisions contained in any supplemental indenture entered into pursuant to Section 14.07 relating either to the kind or

83

Exhibit 4.1

amount of shares of stock or securities or property (including cash) receivable by Holders upon the conversion of their Notes after any event referred to in such Section 14.07 or to any adjustment to be made with respect thereto, but, subject to the provisions of Section 7.01, may accept (without any independent investigation) as conclusive evidence of the correctness of any such provisions, and shall be protected in relying upon, the Officer’s Certificate (which the Company shall be obligated to file with the Trustee prior to the execution of any such supplemental indenture) with respect thereto. Neither the Trustee nor the Conversion Agent shall be responsible for determining whether any event contemplated by Section 14.01(b) has occurred that makes the Notes eligible for conversion or no longer eligible therefor until the Company has delivered to the Trustee and the Conversion Agent the notices referred to in Section 14.01(b) with respect to the commencement or termination of such conversion rights, on which notices the Trustee and the Conversion Agent may conclusively rely, and the Company agrees to deliver such notices to the Trustee and the Conversion Agent immediately after the occurrence of any such event or at such other times as shall be provided for in Section 14.01(b). Except as otherwise expressly provided herein, neither the Trustee nor any other agent acting under this Indenture (other than the Company, if acting in such capacity) shall have any obligation to make any calculation or to determine whether the Notes may be surrendered for conversion pursuant to this Indenture, or to notify the Company or the Depositary or any of the Holders if the Notes have become convertible pursuant to the terms of this Indenture.

Section 14.10. [Reserved].

Section 14.11. Stockholder Rights Plans. If the Company has a stockholder rights plan in effect upon conversion of the Notes, each share of Common Stock, if any, issued upon such conversion shall be entitled to receive the appropriate number of rights, if any, and the certificates representing the Common Stock issued upon such conversion shall bear such legends, if any, in each case as may be provided by the terms of any such stockholder rights plan, as the same may be amended from time to time. However, if, prior to any conversion of Notes, the rights have separated from the shares of Common Stock in accordance with the provisions of the applicable stockholder rights plan, the Conversion Rate shall be adjusted at the time of separation as if the Company distributed to all or substantially all holders of the Common Stock Distributed Property as provided in Section 14.04(c), subject to readjustment in the event of the expiration, termination or redemption of such rights.

Section 14.12. Exchange in Lieu of Conversion. (a) When a Holder surrenders Notes for conversion, the Company may, at its election, direct the Conversion Agent to surrender, on or prior to the Scheduled Trading Day immediately preceding the first Trading Day of the applicable Observation Period, such Notes to a financial institution designated by the Company for exchange in lieu of conversion (each, an “Exchange in Lieu of Conversion”). The Conversion Agent shall be entitled to conclusively rely upon the Company’s instruction in connection with effecting such exchange election and shall have no liability in respect of such exchange election. In order to accept any Notes surrendered for conversion, the designated financial institution must agree to pay and, if applicable, deliver, in exchange for such Notes, all of the cash and shares of Common Stock, if any, due upon conversion, all in accordance with Section 14.02. By the close of business on the Scheduled Trading Day immediately preceding

84

Exhibit 4.1

the first Trading Day of the applicable Observation Period, the Company shall notify the Holder surrendering Notes for conversion, the Trustee and the Conversion Agent (if other than the Trustee) in writing that the Company has directed the designated financial institution to make an Exchange in Lieu of Conversion.

(b) If the designated financial institution accepts any such Notes, it shall pay and, if applicable, deliver, the cash and shares of Common Stock, if any, due upon conversion to such Holder on the second Business Day immediately following the last Trading Day of the applicable Observation Period. Any Notes exchanged by the designated institution shall remain outstanding. If the designated financial institution agrees to accept any Notes for exchange but does not timely pay and, if applicable, deliver the related cash and shares of Common Stock if any, or if such designated financial institution does not accept the Notes for exchange, the Company shall convert the Notes and pay and, if applicable, deliver, the cash and shares of Common Stock, if any, due upon conversion on the second Business Day immediately following the last Trading Day of the applicable Observation Period in accordance with Section 14.02.

(c) The Company’s designation of a financial institution to which the Notes may be submitted for exchange does not require the financial institution to accept any Notes (unless the financial institution has separately made an agreement with the Company). The Company may, but shall not be obligated to, enter into a separate agreement with any designated financial institution that would compensate the Company for any such transaction.

Article 15
Repurchase of Notes at Option of Holders

Section 15.01. [Intentionally Omitted].

Section 15.02. Repurchaseat Option of Holders Upon a Fundamental Change. (a) If a Fundamental Change (other than an Exempted Fundamental Change) occurs at any time, each Holder shall have the right, at such Holder’s option, to require the Company to repurchase for cash all of such Holder’s Notes, or any portion thereof that is equal to $1,000 or an integral multiple of $1,000, on the date (the “Fundamental Change Repurchase Date”) specified by the Company that is not less than 20 calendar days or more than 35 calendar days following the date of the Fundamental Change Company Notice at a repurchase price equal to 100% of the principal amount thereof, plus accrued and unpaid interest thereon to, but excluding, the Fundamental Change Repurchase Date (the “Fundamental Change Repurchase Price”), unless the Fundamental Change Repurchase Date falls after a Regular Record Date but on or prior to the Interest Payment Date to which such Regular Record Date relates, in which case the Company shall instead pay the full amount of accrued and unpaid interest to Holders of record as of such Regular Record Date, and the Fundamental Change Repurchase Price shall be equal to 100% of the principal amount of Notes to be repurchased pursuant to this Article 15. The Fundamental Change Repurchase Date shall be subject to postponement in order to allow the Company to comply with applicable law.

85

Exhibit 4.1

(b) Repurchases of Notes under this Section 15.02 shall be made, at the option of the Holder thereof, upon:

(i) delivery to the applicable Paying Agent by a Holder of a duly completed notice (the “Fundamental Change Repurchase Notice”) in the form set forth in Attachment 2 to the Form of Note attached hereto as Exhibit A, if the Notes are Physical Notes, or in compliance with the Depositary’s procedures for surrendering interests in Global Notes, if the Notes are Global Notes, in each case on or before the close of business on the Business Day immediately preceding the Fundamental Change Repurchase Date; and

(ii) delivery of the Notes, if the Notes are Physical Notes, to the applicable Paying Agent at any time after delivery of the Fundamental Change Repurchase Notice (together with all necessary endorsements for transfer) at the Corporate Trust Office of the applicable Paying Agent, or book-entry transfer of the Notes, if the Notes are Global Notes, in compliance with the procedures of the Depositary, in each case such delivery being a condition to receipt by the Holder of the Fundamental Change Repurchase Price therefor.

The Fundamental Change Repurchase Notice in respect of any Notes to be repurchased shall state:

(i) in the case of Physical Notes, the certificate numbers of the Notes to be delivered for repurchase;

(ii) the portion of the principal amount of Notes to be repurchased, which must be in an Authorized Denomination; and

(iii) that the Notes are to be repurchased by the Company pursuant to the applicable provisions of the Notes and this Indenture;

provided, however, that if the Notes are Global Notes, the Fundamental Change Repurchase Notice must comply with appropriate Depositary procedures.

Notwithstanding anything herein to the contrary, any Holder delivering to the applicable Paying Agent the Fundamental Change Repurchase Notice contemplated by this Section 15.02 shall have the right to withdraw, in whole or in part, such Fundamental Change Repurchase Notice at any time prior to the close of business on the Business Day immediately preceding the Fundamental Change Repurchase Date by delivery of a written notice of withdrawal to the applicable Paying Agent in accordance with Section 15.03.

The applicable Paying Agent shall promptly notify the Company of the receipt by it of any Fundamental Change Repurchase Notice or written notice of withdrawal thereof.

(c) On or before the 20th calendar day after the occurrence of the effective date of a Fundamental Change, the Company shall provide to all Holders of Notes, the Trustee, the

86

Exhibit 4.1

Conversion Agent (if other than the Trustee) and the applicable Paying Agent (in the case of a Paying Agent other than the Trustee or the Paying Agent for the Notes as defined in Section 4.02) a written notice (the “Fundamental Change Company Notice”) of the occurrence of the effective date of the Fundamental Change and of the repurchase right at the option of the Holders arising as a result thereof. In the case of Physical Notes, such notice shall be by first class mail, or, in the case of Global Notes, such notice shall be delivered in accordance with the applicable procedures of the Depositary. Each Fundamental Change Company Notice shall specify:

(i) the events causing the Fundamental Change;

(ii) the date of the Fundamental Change;

(iii) the last date on which a Holder may exercise the repurchase right pursuant to this Article 15;

(iv) the Fundamental Change Repurchase Price;

(v) the Fundamental Change Repurchase Date;

(vi) the name and address of the Paying Agent and the Conversion Agent, if applicable;

(vii) if applicable, the Conversion Rate and any adjustments to the Conversion Rate;

(viii) that the Notes with respect to which a Fundamental Change Repurchase Notice has been delivered by a Holder may be converted only if the Holder withdraws the Fundamental Change Repurchase Notice in accordance with the terms of this Indenture; and

(ix) the procedures that Holders must follow to require the Company to repurchase their Notes.

No failure of the Company to give the foregoing notices and no defect therein shall limit the Holders’ repurchase rights or affect the validity of the proceedings for the repurchase of the Notes pursuant to this Section 15.02.

At the Company’s request, given at least five days prior to the date the Fundamental Change Company Notice is to be sent to the Holders (or such shorter period as agreed by the Paying Agent), the Paying Agent shall give such notice in the Company’s name and at the Company’s expense; provided, however, that, in all cases, the text of such Fundamental Change Company Notice shall be prepared by the Company.

(d) Notwithstanding the foregoing, no Notes may be repurchased by the Company on any date at the option of the Holders upon a Fundamental Change if the principal amount of the Notes has been accelerated, and such acceleration has not been rescinded, on or prior to such

87

Exhibit 4.1

date (except in the case of an acceleration resulting from a Default by the Company in the payment of the Fundamental Change Repurchase Price with respect to such Notes). The applicable Paying Agent will promptly return to the respective Holders thereof any Physical Notes held by it during the acceleration of the Notes (except in the case of an acceleration resulting from a Default by the Company in the payment of the Fundamental Change Repurchase Price with respect to such Notes), or any instructions for book-entry transfer of the Notes in compliance with the procedures of the Depositary shall be deemed to have been cancelled, and, upon such return or cancellation, as the case may be, the Fundamental Change Repurchase Notice with respect thereto shall be deemed to have been withdrawn.

(e) Notwithstanding anything to the contrary in this Article 15, the Company shall not be required to repurchase or make an offer to repurchase Notes upon the occurrence of a Fundamental Change if a third party makes such an offer in the same manner, at the same time and otherwise in compliance with the requirements set forth in this Article 15, and such third party repurchases all Notes properly surrendered and not validly withdrawn upon such offer in compliance with the requirements set forth in this Article 15 for repurchase upon such Fundamental Change by the Company.

(f) For purposes of this Article 15, the Paying Agent may be any agent, depositary, tender agent, paying agent or other agent appointed by the Company to accomplish the purposes set forth herein.

(g) Notwithstanding anything to the contrary, the Company shall not be required to send a Fundamental Change Company Notice, or offer to repurchase any Notes, as set forth in this Article 15, in connection with a Fundamental Change occurring pursuant to clause (b)(B) of the definition thereof (or pursuant to clause (a) that also constitutes a Fundamental Change occurring pursuant to clause (b)(B) of the definition thereof), if: (1) such Fundamental Change constitutes a Share Exchange Event whose Reference Property consists entirely of cash in U.S. dollars; (2) immediately after such Fundamental Change, the Notes become convertible (pursuant to the provisions described in Section 14.07 and, if applicable, Section 14.03) into solely such cash in an amount per $1,000 principal amount of Notes that equals or exceeds the Fundamental Change Repurchase Price per $1,000 principal amount of Notes (calculated assuming that the same includes accrued interest to, but excluding, the latest possible Fundamental Change Repurchase Date for such Fundamental Change); and (3) the Company timely sends the notice relating to such Fundamental Change required pursuant to Section 14.01(b)(iii). Any Fundamental Change with respect to which, in accordance with the provisions described in this Section 15.02(g), the Company is not required to offer to repurchase any Notes is referred to as herein as an “Exempted Fundamental Change.”

Section 15.03. Withdrawal of Fundamental Change Repurchase Notice. (a) A Fundamental Change Repurchase Notice may be withdrawn (in whole or in part) by means of a written notice of withdrawal delivered to the Corporate Trust Office of the applicable Paying Agent in accordance with this Section 15.03 at any time prior to the close of business on the Business Day immediately preceding the Fundamental Change Repurchase Date, specifying:

88

Exhibit 4.1

(i) the aggregate principal amount of the Notes with respect to which such notice of withdrawal is being submitted,

(ii) if Physical Notes have been issued, the certificate number of the Note in respect of which such notice of withdrawal is being submitted, and

(iii) the aggregate principal amount, if any, of such Note that remains subject to the original Fundamental Change Repurchase Notice, which portion must be in an Authorized Denomination;

provided, however, that if the Notes are Global Notes, the notice must comply with appropriate procedures of the Depositary.

Section 16.02. Notice of Optional Redemption; Selection of Notes. (a) In case the Company exercises its Optional Redemption right to redeem all or, as the case may be, any part of the Notes pursuant to Section 16.01, it shall fix a date for redemption (each, a “Redemption Date”) and the Company (or, at the Company’s written request (with such request including an Officer’s Certificate requesting that the Trustee give such Redemption Notice, setting forth the information to be stated in such Redemption Notice as provided in Section 16.02(c), and stating that all conditions precedent to the delivery of such Redemption Notice have been or will be complied with) received by the Trustee at least five Business Days prior to the date of giving the Redemption Notice (or such shorter period of time as may be acceptable to the Trustee), the Trustee, in the name of and at the expense of the Company) shall deliver or cause to be delivered a written notice of such Optional Redemption (a “Redemption Notice”) not less than 55 nor more than 75 Scheduled Trading Days prior to the Redemption Date to the Trustee, the Conversion Agent (if other than the Trustee), the Paying Agent and each Holder of Notes so to be redeemed as a whole or in part.

Exhibit 4.1

Company shall not specify a Redemption Date that falls on or after the 51st Scheduled Trading Day immediately preceding the Maturity Date.

(b) The Redemption Notice, if delivered in the manner herein provided, shall be conclusively presumed to have been duly given, whether or not the Holder receives such notice. In any case, failure to duly give such Redemption Notice or any defect in the Redemption Notice to the Holder of any Note designated for redemption as a whole or in part shall not affect the validity of the proceedings for the redemption of any other Note.

(c) Each Redemption Notice shall specify:

(i) the Redemption Date;

(ii) the Redemption Price;

(iii) that on the Redemption Date, the Redemption Price will become due and payable upon each Note to be redeemed, and that interest thereon, if any, shall cease to accrue on and after the Redemption Date (except as provided in the parenthetical of the definition of Redemption Price);

(iv) the place or places where such Notes are to be surrendered for payment of the Redemption Price;

(v) that Holders may surrender their Notes called (or deemed called) for redemption for conversion at any time prior to the close of business on the Scheduled Trading Day immediately preceding the Redemption Date;

Each Redemption Notice shall be irrevocable.

(d) If the Company elects to redeem fewer than all of the outstanding Notes, at least $75.0 million aggregate principal amount of Notes must be outstanding and not subject to redemption as of the date of the relevant Redemption Notice (such requirement, the “Partial

91

Exhibit 4.1

Redemption Limitation”). If the Company decides to redeem fewer than all of the outstanding Notes and the Notes to be redeemed are Global Notes, the Notes to be redeemed shall be selected by the Depositary in accordance with the applicable procedures of the Depositary. If the Company decides to redeem fewer than all of the outstanding Notes and the Notes to be redeemed are not Global Notes then held by the Depositary, the Trustee shall select the Notes or portions thereof to be redeemed (in Authorized Denominations) by lot, on a pro rata basis or by another method the Trustee considers to be fair and appropriate. If any Note selected for partial redemption is submitted for conversion in part after such selection, the portion of the Note submitted for conversion shall be deemed (so far as may be possible) to be the portion selected for redemption.

Section 16.03. Payment of Notes Called for Redemption. (a) If any Redemption Notice has been given in respect of the Notes in accordance with Section 16.02, the Notes shall become due and payable on the Redemption Date at the place or places stated in the Redemption Notice and at the applicable Redemption Price.

Subject to receipt of funds by the Paying Agent, payment for the Notes to be redeemed shall be made on the Redemption Date for such Notes. The Paying Agent shall, promptly after such payment and upon written demand by the Company, return to the Company any funds in excess of the Redemption Price.

Section 16.04. Restrictions on Redemption. The Company may not redeem any Notes on any date if the principal amount of the Notes has been accelerated in accordance with the terms of this Indenture, and such acceleration has not been rescinded, on or prior to the Redemption Date (except in the case of an acceleration resulting from a Default by the Company in the payment of the Redemption Price with respect to such Notes).

Additional Notes may be issued in an unlimited aggregate principal amount, subject to certain conditions specified in the Indenture. Capitalized terms used in this Note and not defined in this Note shall have the respective meanings set forth in the Indenture.

In case certain Events of Default shall have occurred and be continuing, the principal of, and interest on, all Notes may be declared, by either the Trustee or Holders of at least 25% in aggregate principal amount of Notes then outstanding, and upon said declaration shall become, due and payable, in the manner, with the effect and subject to the conditions and certain exceptions set forth in the Indenture.

Subject to the terms and conditions of the Indenture, the Company will make all payments and deliveries in respect of the Fundamental Change Repurchase Price on the Fundamental Change Repurchase Date, the Redemption Price on any Redemption Date and the principal amount on the Maturity Date, as the case may be, to the Holder who surrenders a Note to a Paying Agent to collect such payments in respect of the Note. The Company will pay cash amounts in money of the United States that at the time of payment is legal tender for payment of public and private debts.

The Indenture contains provisions permitting the Company and the Trustee in certain circumstances, without the consent of the Holders of the Notes, and in certain other circumstances, with the consent of the Holders of not less than a majority in aggregate principal amount of the Notes at the time outstanding, evidenced as in the Indenture provided, to execute supplemental indentures modifying the terms of the Indenture and the Notes as described therein. It is also provided in the Indenture that, subject to certain exceptions, the Holders of a majority in aggregate principal amount of the Notes at the time outstanding may on behalf of the Holders of all of the Notes waive any past Default or Event of Default under the Indenture and its consequences.

Each Holder shall have the right to institute suit for the enforcement of its right to receive payment or delivery, as the case may be, of (x) the principal (including the Redemption Price and the Fundamental Change Repurchase Price, if applicable) of, (y) accrued and unpaid interest, if any, on, and (z) the consideration due upon conversion of, this Note at the place, at the respective

The Notes shall be redeemable at the Company’s option on or after March 8, 2027 in accordance with the terms and subject to the conditions specified in the Indenture. No sinking fund is provided for the Notes.

suspension or limitation imposed on trading (by reason of movements in price exceeding limits permitted by the relevant stock exchange or otherwise) in the Shares or in any options contracts or futures contracts relating to the Shares.”

Settlement Terms.

Settlement Method: For any Option, Net Share Settlement; provided that if the Relevant Settlement Method set forth below for such Option is not Net Share Settlement, then the Settlement Method for such Option shall be such Relevant Settlement Method, but only if Counterparty shall have delivered to Dealer a valid Notice of Final Settlement Method as set forth above for such Option.

Relevant Settlement Method: In respect of any Option:

(i) if Counterparty has elected, or is deemed to have elected, to settle its conversion obligations in respect of the related Convertible Note in a combination of cash and Shares pursuant to Section 14.02(a) of the Indenture with a Specified Cash Amount equal to USD 1,000, then the Relevant Settlement Method for such Option shall be Net Share Settlement;

Exhibit 10.1

Dealer will pay cash in lieu of delivering any fractional Shares to be delivered with respect to any Net Share Settlement Amount valued at the Relevant Price for the last Valid Day of the Settlement Averaging Period.

(i) cash (the “Combination Settlement Cash Amount”) equal to the sum, for each Valid Day during the Settlement Averaging Period for such Option, of (A) an amount (the “Daily Combination Settlement Cash Amount”) equal to the lesser of (1) the product of (x) the Applicable Percentage and (y) the Specified Cash Amount minus USD 1,000 and (2) the Daily Option Value, divided by (B) the number of Valid Days in the Settlement Averaging Period; provided that if the calculation in clause (A) above results in zero or a negative number for any Valid Day, the Daily Combination Settlement Cash Amount for such Valid Day shall be deemed to be zero; and

(ii) Shares (the “Combination Settlement Share Amount”) equal to the sum, for each Valid Day during the Settlement Averaging Period for such Option, of a number of Shares for such Valid Day (the “Daily Combination Settlement Share Amount”) equal to (A) (1) the Daily Option Value on such Valid Day minus the Daily Combination Settlement Cash Amount for such Valid Day, divided by (2) the Relevant Price on such Valid Day, divided by (B) the number of Valid Days in the Settlement Averaging Period; provided that if the calculation in sub-clause (A)(1) above results in zero or a negative number for any Valid Day, the Daily Combination Settlement Share Amount for such Valid Day shall be deemed to be zero;

provided that in no event shall the sum of (x) the Combination Settlement Cash Amount for any Option, (y) the Combination Settlement Share Amount (not including any such amount representing a fractional share) for such Option multiplied by the Applicable Limit Price on the Settlement Date for such Option and (z) the cash to be paid by Dealer in lieu of a fractional share, exceed the Applicable Limit for such Option.

Dealer will pay cash in lieu of delivering any fractional Shares to be delivered with respect to any Combination Settlement Share Amount valued at the Relevant Price for the last Valid Day of the Settlement Averaging Period.

Cash Settlement: If Cash Settlement is applicable to any Option exercised or deemed exercised hereunder, in lieu of Section 8.1 of the

7

Exhibit 10.1

Equity Definitions, Dealer will pay to Counterparty, on the relevant Settlement Date for each such Option, an amount of cash (the “Cash Settlement Amount”) equal to the sum, for each Valid Day during the Settlement Averaging Period for such Option, of (i) the Daily Option Value for such Valid Day, divided by (ii) the number of Valid Days in the Settlement Averaging Period; provided that in no event shall the Cash Settlement Amount for any Option exceed the Applicable Limit for such Option.

Daily Option Value: For any Valid Day, an amount equal to (i) the Option Entitlement on such Valid Day, multiplied by (ii) (A) the lesser of the Relevant Price on such Valid Day and the Cap Price, less (B) the Strike Price on such Valid Day; provided that if the calculation contained in clause (ii) above results in a negative number, the Daily Option Value for such Valid Day shall be deemed to be zero. In no event will the Daily Option Value be less than zero.

Applicable Limit: For any Option, an amount of cash equal to the Applicable Percentage multiplied by the excess of (i) the aggregate of (A) the amount of cash paid to the “Holder” (as such term is defined in the Indenture) of the related Convertible Note upon conversion of such Convertible Note and (B) the number of Shares, if any, delivered to the “Holder” (as such term is defined in the Indenture) of the related Convertible Note upon conversion of such Convertible Note multiplied by the Applicable Limit Price on the Settlement Date for such Option, over (ii) USD 1,000.

Applicable Limit Price: On any day, the opening price as displayed under the heading “Op” on Bloomberg page PSN<equity> (or any successor thereto).

Valid Day: Any day on which (i) trading in the Shares generally occurs on the Exchange or, if the Shares are not then listed on the Exchange, on the principal other U.S. national or regional securities exchange on which the Shares are then listed or, if the Shares are not then listed on a U.S. national or regional securities exchange, on the principal other market on which the Shares are then listed or admitted for trading; and (ii) there is no Market Disruption Event. If the Shares are not so listed or admitted for trading, then “Valid Day” means a Business Day.

Exhibit 10.1

on Bloomberg page “PSN <equity> AQR” (or its equivalent successor if such page is not available) in respect of the period from the scheduled open of trading until the scheduled close of trading of the primary trading session on such Valid Day (or if such volume-weighted average price is unavailable at such time, the market value of one Share on such Valid Day, as determined by the Calculation Agent in a commercially reasonable manner using, if practicable, a volume-weighted average method). The Relevant Price will be determined without regard to after-hours trading or any other trading outside of the regular trading session trading hours.

Representation and Agreement: Notwithstanding anything to the contrary in the Equity Definitions (including, but not limited to, Section 9.11 thereof), the parties acknowledge that (i) any Shares delivered to Counterparty shall be, upon delivery, subject to restrictions and limitations arising from Counterparty’s status as issuer of the Shares under applicable securities laws, (ii) Dealer may deliver any Shares required to be delivered hereunder in certificated form in lieu of delivery through the Clearance System and (iii) any Shares delivered to Counterparty may be “restricted securities” (as defined in Rule 144 under the Securities Act of 1933, as amended (the “Securities Act”)).

3.Additional Terms applicable to the Transaction.

Adjustments applicable to the Transaction:

Potential Adjustment Events: Notwithstanding Section 11.2(e) of the Equity Definitions, a “Potential Adjustment Event” means an occurrence of any event or condition, as set forth in any Dilution Adjustment Provision, that would result in an adjustment under the Indenture to the [“Conversion Rate” or the composition of a “unit of Reference Property” or to any “Last Reported Sale Price,” “Daily Measurement Value,” “Daily Conversion Value,” “Daily Settlement Amount” or “Daily VWAP”] (each such term as defined in the

9

Exhibit 10.1

Indenture). For the avoidance of doubt, Dealer shall not have any delivery or payment obligation hereunder, and except as set forth in Section 9(x), no adjustment shall be made to the terms of the Transaction, on account of (x) any distribution of cash, property or securities by Counterparty to “Holders” (as such term is defined in the Indenture) (upon conversion or otherwise) or (y) any other transaction in which “Holders” (as such term is defined in the Indenture) are entitled to participate, in each case, in lieu of an adjustment under the Indenture of the type referred to in the immediately preceding sentence (including, without limitation, pursuant to the fourth sentence of the first paragraph of Section 14.04(c) of the Indenture or the fourth sentence of Section 14.04(d) of the Indenture).

Method of Adjustment: Calculation Agent Adjustment, which means that, notwithstanding Section 11.2(c) of the Equity Definitions, upon any Potential Adjustment Event, the Calculation Agent shall make an adjustment to any one or more of the Strike Price, Number of Options, Option Entitlement and any other variable relevant to the exercise, settlement or payment for the Transaction that corresponds to the adjustments to the Convertible Notes under the Indenture; provided that the parties agree that (x) open market Share repurchases at prevailing market prices and (y) Share repurchases through a dealer pursuant to accelerated share repurchases, forward contracts or similar transactions that are entered into at prevailing market prices and in accordance with customary market terms for transactions of such type to repurchase the Shares shall not be considered Potential Adjustment Events, in each case, to the extent that, after giving effect to such transactions, the aggregate number of Shares repurchased during the term of the Transaction pursuant to all transactions described in this proviso would not reduce the number of Shares outstanding to be less than [ ] Shares, as determined by the Calculation Agent and as adjusted by the Calculation Agent to account for any subdivision or combination with respect to the Shares.

Notwithstanding the foregoing and “Consequences of Merger Events / Tender Offers” below:

(i) if the Calculation Agent in good faith disagrees with any adjustment to the Convertible Notes that involves an exercise of discretion by Counterparty or its board of directors (including, without limitation, pursuant to Section 14.05 of the Indenture, Section 14.07(a) of the Indenture or any supplemental indenture entered into thereunder or in connection with any proportional adjustment or the determination of the fair value of any securities, property, rights or other assets), then in each such case, the Calculation Agent will, in good faith and in a commercially reasonable manner and, if applicable, consistent with the

10

Exhibit 10.1

methodology set forth in the Indenture, determine the adjustment to be made to any one or more of the Strike Price, Number of Options, Option Entitlement and any other variable relevant to the exercise, settlement or payment for the Transaction in a commercially reasonable manner;

(ii) in connection with any Potential Adjustment Event as a result of an event or condition set forth in Section 14.04(b) of the Indenture or Section 14.04(c) of the Indenture where, in either case, the period for determining “Y” (as such term is used in Section 14.04(b) of the Indenture) or “SP0” (as such term is used in Section 14.04(c) of the Indenture), as the case may be, begins before Counterparty has publicly announced the event or condition giving rise to such Potential Adjustment Event, then the Calculation Agent shall, in good faith and in a commercially reasonable manner, have the right to adjust any variable relevant to the exercise, settlement or payment for the Transaction as appropriate to reflect the costs (including, but not limited to, hedging mismatches and market losses) and expenses incurred by Dealer in connection with its hedging activities, with such adjustments made assuming that Dealer maintains commercially reasonable hedge positions, as a result of such event or condition not having been publicly announced prior to the beginning of such period; and

(iii) if any Potential Adjustment Event is declared and (a) the event or condition giving rise to such Potential Adjustment Event is subsequently amended, modified, cancelled or abandoned, (b) the “Conversion Rate” (as such term is defined in the Indenture) is otherwise not adjusted at the time or in the manner contemplated by the relevant Dilution Adjustment Provision based on such declaration or (c) the “Conversion Rate” (as such term is defined in the Indenture) is adjusted as a result of such Potential Adjustment Event and subsequently re-adjusted (each of clauses (a), (b) and (c), a “Potential Adjustment Event Change”) then, in each case, the Calculation Agent shall, in good faith and in a commercially reasonable manner, have the right to adjust any variable relevant to the exercise, settlement or payment for the Transaction as appropriate to reflect the costs (including, but not limited to, hedging mismatches and market losses) and expenses incurred by Dealer in connection with its hedging activities, with such adjustments made assuming that Dealer maintains commercially

11

Exhibit 10.1

reasonable hedge positions, as a result of such Potential Adjustment Event Change.

Dilution Adjustment Provisions: Sections 14.04(a), (b), (c), (d) and (e) and Section 14.05 of the Indenture.

Tender Offers: Notwithstanding Section 12.2 and Section 12.3 of the Equity Definitions, upon the occurrence of a Merger Event or a Tender Offer, the Calculation Agent shall make a corresponding adjustment in respect of any adjustment under the Indenture to any one or more of the nature of the Shares (in the case of a Merger Event), Strike Price, Number of Options, Option Entitlement and any other variable relevant to the exercise, settlement or payment for the Transaction, subject to the second paragraph under “Method of Adjustment”; provided, however, that such adjustment shall be made without regard to any adjustment to the “Conversion Rate” (as such term is defined in the Indenture) pursuant to any Excluded Provision; provided further that if, with respect to a Merger Event or a Tender Offer, (i) the consideration for the Shares includes (or, at the option of a holder of Shares, may include) shares of an entity or person that is not a corporation or is not organized under the laws of the United States, any State thereof or the District of Columbia or (ii) the Counterparty to the Transaction following such Merger Event or Tender Offer will not be a corporation organized under the laws of the United States, any State thereof or the District of Columbia, then, in either case, Cancellation and Payment (Calculation Agent Determination) may apply at Dealer’s reasonable election; provided further that, for the avoidance of doubt, adjustments shall be made pursuant to the provisions set forth above regardless of whether any Merger Event or Tender Offer gives rise to an Early Conversion.

For purposes of this definition of “Announcement Event,” (A) “Merger Event” shall mean

13

Exhibit 10.1

(b)Repurchase Notices. Counterparty shall, on any day on which Counterparty effects any repurchase of Shares, promptly give Dealer a written notice (which, for the avoidance of doubt may be by email) of such repurchase (a “Repurchase Notice”) on such day if following such repurchase, the number

Exhibit 10.1

of outstanding Shares as determined on such day is (i) less than [  ] million (in the case of the first such notice) or (ii) thereafter more than [  ] million less than the number of Shares included in the immediately preceding Repurchase Notice; provided that, with respect to any repurchase of Shares pursuant to a plan under Rule 10b5-1 under the Exchange Act (as defined below), Counterparty may elect to satisfy such requirement by promptly giving Dealer written notice of entry into such plan, the maximum number of Shares that may be purchased thereunder and the approximate dates or periods during which such repurchases may occur (with such maximum number of Shares deemed repurchased on the date of such notice for purposes of this Section 9(b)). Counterparty agrees to indemnify and hold harmless Dealer and its affiliates and their respective officers, directors, employees, affiliates, advisors, agents and controlling persons (each, an “Indemnified Person”) from and against any and all commercially reasonable losses (including losses relating to Dealer’s commercially reasonable hedging activities as a consequence of becoming, or of the risk of becoming, a Section 16 “insider”, including without limitation, any forbearance from hedging activities or cessation of hedging activities and any losses in connection therewith with respect to the Transaction), claims, damages, judgments, liabilities and reasonable and documented out-of-pocket expenses (including reasonable attorney’s fees), joint or several, which an Indemnified Person may become subject to, as a result of Counterparty’s failure to provide Dealer with a Repurchase Notice on the day and in the manner specified in this paragraph, and to reimburse, within 30 days, upon written request, each of such Indemnified Persons for any reasonable legal or other out-of-pocket expenses incurred in connection with investigating, preparing for, providing testimony or other evidence in connection with or defending any of the foregoing. If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted against the Indemnified Person as a result of Counterparty’s failure to provide Dealer with a Repurchase Notice in accordance with this paragraph, such Indemnified Person shall promptly notify Counterparty in writing, and Counterparty, upon request of the Indemnified Person, shall retain counsel reasonably satisfactory to the Indemnified Person to represent the Indemnified Person and any others Counterparty may designate in such proceeding and shall pay the reasonable fees and expenses of such counsel related to such proceeding. Counterparty shall not be liable for any settlement of any proceeding contemplated by this paragraph that is effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, Counterparty agrees to indemnify any Indemnified Person from and against any loss or liability by reason of such settlement or judgment. Counterparty shall not, without the prior written consent of the Indemnified Person, effect any settlement of any pending or threatened proceeding contemplated by this paragraph that is in respect of which any Indemnified Person is or could have been a party and indemnity could have been sought hereunder by such Indemnified Person, unless such settlement includes an unconditional release of such Indemnified Person from all liability on claims that are the subject matter of such proceeding on terms reasonably satisfactory to such Indemnified Person. If the indemnification provided for in this paragraph is unavailable to an Indemnified Person or insufficient in respect of any commercially reasonable losses, claims, damages or liabilities referred to therein, then Counterparty hereunder, in lieu of indemnifying such Indemnified Person thereunder, shall contribute to the amount paid or payable by such Indemnified Person as a result of such losses, claims, damages or liabilities. The remedies provided for in this paragraph ‎(b) are not exclusive and shall not limit any rights or remedies which may otherwise be available to any Indemnified Person at law or in equity.

(e)Transfer or Assignment.

(i)Counterparty shall have the right to transfer or assign its rights and obligations hereunder with respect to all, but not less than all, of the Options hereunder (such Options, the “Transfer Options”); provided that such transfer or assignment shall be subject to reasonable conditions that Dealer may impose, including but not limited, to the following conditions:

(A) With respect to any Transfer Options, Counterparty shall not be released from its notice and indemnification obligations pursuant to Section 9(b) or any obligations under Section 9(n) or 9(s) of this Confirmation;

(B) Any Transfer Options shall only be transferred or assigned to a third party that is a United States person (as defined in the Internal Revenue Code of 1986, as amended (the “Code”));

(C) Such transfer or assignment shall be effected on terms, including any reasonable undertakings by such third party (including, but not limited to, an undertaking with respect to compliance with applicable securities laws in a manner that, in the reasonable judgment of Dealer, will not expose Dealer to material risks under applicable securities laws) and execution of any documentation and delivery of legal opinions with respect to securities laws and other matters by such third party and Counterparty, as are requested and reasonably satisfactory to Dealer;

(D) Dealer will not, as a result of such transfer and assignment, be required to pay the transferee on any payment date an amount under Section 2(d)(i)(4) of the Agreement greater than an amount that Dealer would have been required to pay to Counterparty in the absence of such transfer and assignment;

(E) Dealer will not, as a result of such transfer or assignment, receive from the transferee or assignee on any payment date (after accounting for amounts paid by the transferee or assignee under Section 2(d)(i)(4) of the Agreement as well as any withholding or deduction of Tax from the payment) an amount less than it would have been entitled to receive from Counterparty in the absence of such transfer or assignment;

(F) An Event of Default, Potential Event of Default or Termination Event will not occur as a result of such transfer and assignment;

(G) Without limiting the generality of clause (B), the transferee or assignee shall make such Payee Tax Representations and provide such tax documentation as may be reasonably requested by Dealer to permit Dealer to determine that results described in clauses (D) and (E) will not occur upon or after such transfer and assignment; and

(H) Counterparty shall be responsible for all reasonable costs and expenses, including reasonable counsel fees, incurred by Dealer in connection with such transfer or assignment.

(ii)Dealer may transfer or assign all or any part of its rights or obligations under the Transaction (A) without Counterparty’s consent (but with prompt subsequent (but in no event more than two Exchange Business Days) written notice to Counterparty), to any affiliate of Dealer (1) that has a long-term issuer rating that is equal to or better than Dealer’s credit rating at the time of such transfer or assignment, or (2) whose obligations hereunder will be guaranteed, pursuant to the terms of a customary guarantee in a form used by Dealer generally for similar transactions, by Dealer or Dealer’s ultimate parent, as applicable (provided that in connection with any assignment or transfer pursuant to clause

21

Exhibit 10.1

(A)(2) hereof, the guarantee of any guarantor of the relevant transferee’s obligations under the Transaction shall constitute a Credit Support Document under the Agreement), or (B) with Counterparty’s consent (such consent not to be unreasonably withheld or delayed), to any other third party financial institution that is a recognized dealer in the market for U.S. corporate equity derivatives and that has a long-term issuer rating equal to or better than the lesser of (1) the credit rating of Dealer at the time of the transfer or assignment and (2) A- by S&P Global Ratings, a division of S&P Global Inc., or its successor (“S&P”), or A3 by Moody’s Investors Service, Inc. or its successor (“Moody’s”) or, if either S&P or Moody’s ceases to rate such debt, at least an equivalent rating or better by a substitute rating agency mutually agreed by Counterparty and Dealer; provided that, in the case of any transfer or assignment described in clause (A) or (B) above, (I) such a transfer or assignment shall not occur unless an Event of Default, Potential Event of Default or Termination Event will not occur as a result of such transfer and assignment; and (II) at the time of such transfer or assignment both the Dealer and transferee in any such transfer or assignment are “dealers in securities” within the meaning of Section 475(c)(1) of the Code or the transfer or assignment does not result in a deemed exchange by Counterparty within the meaning of Section 1001 of the Code. In addition, (A) the transferee or assignee shall agree that following such transfer or assignment, Counterparty will not (x) receive from the transferee or assignee on any payment date or delivery date (after accounting for amounts paid by the transferee or assignee under Section 2(d)(i)(4) of the Agreement as well as any withholding or deduction of Tax from the payment or delivery) an amount or a number of Shares, as applicable, lower than the amount or the number of Shares, as applicable, that Counterparty would have been entitled to receive from Dealer in the absence of such transfer or assignment, other than any difference arising from a change in law after the date of such transfer or assignment, or (y) be required to pay such assignee or transferee on any payment date an amount under Section 2(d)(i)(4) of the Agreement greater than an amount that Counterparty would have been required to pay to Dealer in the absence of such transfer or assignment and (B) the transferee or assignee shall make such Payee Tax Representations and shall provide such tax documentation as may be reasonably requested by Counterparty including in order to permit Counterparty to make any necessary determinations pursuant to clause (A) of this sentence. If at any time at which (A) the Section 16 Percentage exceeds 8.0%, (B) the Option Equity Percentage exceeds 14.5%, or (C) the Share Amount exceeds the Applicable Share Limit (if any applies) (any such condition described in clauses (A), (B) or (C), an “Excess Ownership Position”), Dealer is unable after using its commercially reasonable efforts to effect a transfer or assignment of Options to a third party on pricing terms reasonably acceptable to Dealer and within a time period reasonably acceptable to Dealer such that no Excess Ownership Position exists (after giving effect to such transfer or assignment and any resulting change in Dealer’s commercially reasonable Hedge Positions), then Dealer may designate any Exchange Business Day as an Early Termination Date with respect to a portion of the Transaction (the “Terminated Portion”), such that following such partial termination no Excess Ownership Position exists (after giving effect to such transfer or assignment and any resulting change in Dealer’s commercially reasonable Hedge Positions). In the event that Dealer so designates an Early Termination Date with respect to a portion of the Transaction, a payment shall be made pursuant to Section 6 of the Agreement as if (1) an Early Termination Date had been designated in respect of a Transaction having terms identical to the Transaction and a Number of Options equal to the number of Options underlying the Terminated Portion, (2) Counterparty were the sole Affected Party with respect to such partial termination and (3) the Terminated Portion were the sole Affected Transaction (and, for the avoidance of doubt, the provisions of Section ‎9(l) shall apply to any amount that is payable by Dealer to Counterparty pursuant to this sentence as if Counterparty was not the Affected Party). The “Section 16 Percentage” as of any day is the fraction, expressed as a percentage, (A) the numerator of which is the number of Shares that Dealer and any of its affiliates or any other person subject to aggregation with Dealer for purposes of the “beneficial ownership” test under Section 13 of the Exchange Act, or any “group” (within the meaning of Section 13 of the Exchange Act) of which Dealer is or

22

Exhibit 10.1

may be deemed to be a part beneficially owns (within the meaning of Section 13 of the Exchange Act), without duplication, on such day (or, to the extent that for any reason the equivalent calculation under Section 16 of the Exchange Act and the rules and regulations thereunder results in a higher number, such higher number) and (B) the denominator of which is the number of Shares outstanding on such day. The “Option Equity Percentage” as of any day is the fraction, expressed as a percentage, (A) the numerator of which is the sum of (1) the product of the Number of Options and the Option Entitlement and (2) the aggregate number of Shares underlying any other call option transaction sold by Dealer to Counterparty, and (B) the denominator of which is the number of Shares outstanding. The “Share Amount” as of any day is the number of Shares that Dealer and any person whose ownership position would be aggregated with that of Dealer (Dealer or any such person, a “Dealer Person”) under any law, rule, regulation, regulatory order or organizational documents or contracts of Counterparty that are, in each case, applicable to ownership of Shares (“Applicable Restrictions”), owns, beneficially owns, constructively owns, controls, holds the power to vote or otherwise meets a relevant definition of ownership under any Applicable Restriction, as determined by Dealer in its reasonable discretion. The “Applicable Share Limit” means a number of Shares equal to (A) the minimum number of Shares that could give rise to reporting or registration obligations (except for any filing requirements on Form 13F, Schedule 13D or Schedule 13G under the Exchange Act, in each case, as in effect on the Trade Date) or other requirements (including obtaining prior approval from any person or entity) of a Dealer Person, or could result in an adverse effect on a Dealer Person, under any Applicable Restriction, as determined by Dealer in its reasonable discretion, minus (B) 1% of the number of Shares outstanding.

(iii)Notwithstanding any other provision in this Confirmation to the contrary requiring or allowing Dealer to purchase, sell, receive or deliver any Shares or other securities, or make or receive any payment in cash, to or from Counterparty, Dealer may designate any of its affiliates (each, a “Dealer Designated Affiliate”) to purchase, sell, receive or deliver such Shares or other securities, or to make or receive such payment in cash, and otherwise to perform Dealer’s obligations in respect of the Transaction and any such designee may assume such obligations; provided that such Dealer Designated Affiliate shall comply with the provisions of the Transaction in the same manner as Dealer would have been required to comply. Dealer shall be discharged of its obligations to Counterparty to the extent of any such performance.

(f)Staggered Settlement. If upon advice of counsel with respect to applicable legal and regulatory requirements, including any requirements relating to Dealer’s commercially reasonable hedging activities hereunder, Dealer reasonably determines that it would not be practicable or advisable to deliver, or to acquire Shares to deliver, any or all of the Shares to be delivered by Dealer on any Settlement Date for the Transaction, Dealer may, by notice to Counterparty on or prior to any Settlement Date (a “Nominal Settlement Date”), elect to deliver the Shares on two or more dates (each, a “Staggered Settlement Date”) as follows:

(i)in such notice, Dealer will specify to Counterparty the related Staggered Settlement Dates (each of which shall occur on or prior to such Nominal Settlement Date) and the number of Shares that it will deliver on each Staggered Settlement Date;

(ii)the aggregate number of Shares that Dealer will deliver to Counterparty hereunder on all such Staggered Settlement Dates will equal the number of Shares that Dealer would otherwise be required to deliver on such Nominal Settlement Date; and

(iii)if the Net Share Settlement terms or the Combination Settlement terms set forth above were to apply on the Nominal Settlement Date, then the Net Share Settlement terms or the Combination Settlement terms, as the case may be, will apply on each Staggered Settlement Date, except that the Shares otherwise deliverable on such Nominal Settlement Date will be allocated among such Staggered Settlement Dates as specified by Dealer in the notice referred to in clause ‎(i) above.

(h)[Conduct Rules. Each party acknowledges and agrees to be bound by the Conduct Rules of the Financial Industry Regulatory Authority applicable to transactions in options, and further agrees not to violate the position and exercise limits set forth therein.][Reserved.]

(i)Additional Termination Events.

(i)Notwithstanding anything to the contrary in this Confirmation, upon any Early Conversion in respect of which a “Notice of Conversion” (as such term is defined in the Indenture) that is effective as to Counterparty has been delivered in accordance with the Indenture by the relevant converting “Holder” (as such term is defined in the Indenture):

(A) Counterparty shall, within five Scheduled Trading Days of the Conversion Date for such Early Conversion, provide written notice (an “Early Conversion Notice”) to Dealer specifying the number of Convertible Notes surrendered for conversion on such Conversion Date (such Convertible Notes, the “Affected Convertible Notes”), and the giving of such Early Conversion Notice shall constitute an Additional Termination Event as provided in this clause ‎(i);

(B) upon receipt of any such Early Conversion Notice, Dealer shall designate an Exchange Business Day as an Early Termination Date (which Exchange Business Day shall be on or as promptly as reasonably practicable after the related settlement date for such Affected Convertible Notes) with respect to the portion of the Transaction corresponding to a number of Options (the “Affected Number of Options”) equal to the lesser of (x) the number of Affected Convertible Notes [minus the “Affected Number of Options” (as defined in the Base Call Option Confirmation), if any, that relate to such Affected Convertible Notes] and (y) the Number of Options as of the Conversion Date for such Early Conversion;

(C) any payment hereunder with respect to such termination shall be calculated pursuant to Section 6 of the Agreement as if (x) an Early Termination Date had been designated in respect of a Transaction having terms identical to the Transaction and a Number of Options equal to the Affected Number of Options, (y) Counterparty were the sole Affected Party with respect to such Additional Termination Event and (z) the terminated portion of the Transaction were the sole Affected Transaction; provided that the amount payable with respect to such termination shall not be greater than (1) the Applicable Percentage, multiplied by (2) the Affected Number of Options, multiplied by (3) (x) the sum of (i) the amount of cash paid to the “Holder” (as such term is defined in the Indenture) of an Affected Convertible Note upon conversion of such Affected Convertible Note and (ii) the number of Shares delivered (if any) to the “Holder” (as such term is defined in the Indenture) of an Affected Convertible Note upon conversion of such Affected Convertible Note, multiplied by the Applicable Limit Price on the settlement date for the conversion of such Affected Convertible Note (the “Conversion Settlement Date”), minus (y) the Synthetic Instrument Adjusted Issue Price determined by the Calculation Agent by reference to the Conversion Settlement Date. “Synthetic Instrument Adjusted Issue Price” shall mean the amount determined by the Calculation Agent by reference to the table set forth below (the “Synthetic Instrument AIP Table”). If the relevant Conversion Settlement Date is not listed in the Synthetic Instrument AIP Table, the amount in the preceding sentence shall be determined by the Calculation Agent by reference to the Synthetic Instrument AIP Table, using a linear interpolation between the lower and higher Synthetic Instrument Adjusted Issue Prices for the Conversion Settlement Dates immediately preceding and immediately following the relevant Conversion Settlement Date.

24

Exhibit 10.1

Conversion Settlement Date	Synthetic Instrument Adjusted Issue Price
February 26, 2024	$889.50
September 1, 2024	$899.57

March 1, 2028	$975.65
September 1, 2028	$987.67
March 1, 2029	$1,000.00

(D) for the avoidance of doubt, in determining the amount payable in respect of such Affected Transaction pursuant to Section 6 of the Agreement, the Calculation Agent shall assume that (x) the relevant Early Conversion and any conversions, adjustments, agreements, payments, deliveries or acquisitions by or on behalf of Counterparty leading thereto had not occurred, (y) no adjustments to the “Conversion Rate” (as such term is defined in the Indenture) have occurred pursuant to any Excluded Provision and (z) the corresponding Convertible Notes remain outstanding as if the circumstances related to such Early Conversion had not occurred; and

(E) the Transaction shall remain in full force and effect, except that, as of the Conversion Date for such Early Conversion, the Number of Options shall be reduced by the Affected Number of Options.

(ii)Within five Scheduled Trading Days following any Repayment Event (as defined below), Counterparty may notify Dealer of such Repayment Event, in each case, including the number of Convertible Notes subject to such Repayment Event, or, if less, the number of Convertible Notes subject to such Repayment Event that Counterparty elects to be subject to the provisions of this Section 9(i)(ii) (any such notice, a “Repayment Notice”); provided that no such Repayment Notice shall be effective unless it contains the representation by Counterparty set forth in Section 8(f) hereunder as of the date of such Repayment Notice [; providedfurther that any “Repayment Notice” delivered to Dealer pursuant to the Base Call Option Confirmation shall be deemed to be a Repayment Notice pursuant to this Confirmation and the terms of such Repayment Notice shall apply, mutatis mutandis, to this Confirmation]. Notwithstanding anything to the contrary in this Confirmation, the receipt by Dealer from Counterparty of any Repayment Notice shall constitute an Additional Termination Event as provided in this Section 9(i)(ii). Upon receipt of any such Repayment Notice, Dealer shall promptly designate an Exchange Business Day following receipt of such Repayment Notice (which in no event shall be earlier than the related settlement date for the relevant Repayment Event) as an Early Termination Date with respect to the portion of the Transaction corresponding to a number of Options (the “Repayment Options”) equal to the lesser of (A) the number of such Convertible Notes specified in such Repayment Notice [minus the number of “Repayment Options” (as defined in the Base Call Option Confirmation), if any, that relate to such Convertible Notes (and for purposes of determining whether any Options under this Confirmation or under the Base Call Option Confirmation will be among the Repayment Options hereunder or under, and as defined in, the Base Call Option Confirmation, the Convertible Notes specified in such Repayment Notice shall be allocated first to the Base Call Option

25

Exhibit 10.1

Confirmation until all Options thereunder are exercised or terminated)] and (B) the Number of Options as of the date Dealer designates such Early Termination Date and, as of such date, the Number of Options shall be reduced by the number of Repayment Options. Any payment hereunder with respect to such termination (the “Repayment Unwind Payment”) shall be calculated pursuant to Section 6 of the Agreement as if (1) an Early Termination Date had been designated in respect of a Transaction having terms identical to the Transaction and a Number of Options equal to the number of Repayment Options, (2) Counterparty were the sole Affected Party with respect to such Additional Termination Event, (3) the terminated portion of the Transaction were the sole Affected Transaction, (4) the relevant Repayment Event and any conversions, adjustments, agreements, payments, deliveries or acquisitions by or on behalf of Counterparty leading thereto had not occurred, (5) no adjustments to the “Conversion Rate” (as such term is defined in the Indenture) have occurred pursuant to any Excluded Provision and (6) the corresponding Convertible Notes remain outstanding as if the circumstances related to such Repayment Event had not occurred. “Repayment Event” means that (i) any Convertible Notes are repurchased (whether pursuant to Section 15.02 of the Indenture or Article 16 of the Indenture or otherwise) by Counterparty or any of its subsidiaries (including in connection with, or as a result of, a “Fundamental Change” (as such term is defined in the Indenture), a redemption, a tender offer, exchange offer or similar transaction or for any other reason), (ii) any Convertible Notes are delivered to Counterparty in exchange for delivery of any property or assets of Counterparty or any of its subsidiaries (howsoever described), (iii) any principal of any of the Convertible Notes is repaid in full prior to the final maturity date of the Convertible Notes (other than upon acceleration of the Convertible Notes pursuant to Section 6.02 of the Indenture), or (iv) any Convertible Notes are exchanged by or for the benefit of the “Holders” (as such term is defined in the Indenture) thereof for any other securities of Counterparty or any of its affiliates (or any other property, or any combination thereof) pursuant to any exchange offer or similar transaction. For the avoidance of doubt, any conversion of Convertible Notes (whether into cash or a combination of cash and Shares or any “Reference Property” (as such term is defined in the Indenture)) pursuant to the terms of the Indenture shall not constitute a Repayment Event. Counterparty acknowledges and agrees that if an Additional Termination Event has occurred under this Section 9(i)(ii), then any related Convertible Notes subject to a Repayment Event will be deemed to be cancelled and disregarded and no longer outstanding for all purposes hereunder.

(iii)Notwithstanding anything to the contrary in this Confirmation, the occurrence of an event of default with respect to Counterparty under the terms of the Convertible Notes as set forth in Section 6.01 of the Indenture, which default has resulted in the Convertible Notes becoming due and payable under the terms thereof, shall constitute an Additional Termination Event applicable to the Transaction and, with respect to such Additional Termination Event, (A) Counterparty shall be deemed to be the sole Affected Party, (B) the Transaction shall be the sole Affected Transaction and (C) Dealer shall be the party entitled to designate an Early Termination Date pursuant to Section 6(b) of the Agreement.

(j)Amendments to Equity Definitions; Agreement.

(i)Section 11.2(e)(vii) of the Equity Definitions is hereby replaced in its entirety with the words “any other corporate event involving the Issuer that has a material effect on the theoretical value of the Shares or the Options.”

(ii)Section 12.6(a)(ii) of the Equity Definitions is hereby amended by (1) inserting “(1)” immediately following the word “means” in the first line thereof and (2) inserting immediately prior to the semi-colon at the end of subsection (B) thereof the following words: “or (2) the occurrence of any of the events specified in Section 5(a)(vii)(1) through (9) of the ISDA Master Agreement with respect to that Issuer”.

26

Exhibit 10.1

(iii)Section 12.9(b)(i) of the Equity Definitions is hereby amended by (1) replacing “either party may elect” with “Dealer may elect” and (2) replacing “notice to the other party” with “notice to Counterparty” in the first sentence of such section.

(iv)Section 12(a) of the Agreement is hereby amended by (1) deleting the phrase “or email” in the third line thereof and (2) deleting the phrase “or that communication is delivered (or attempted) or received, as applicable, after the close of business on a Local Business Day” in the final clause thereof.

(k)No Setoff. Each party waives any and all rights it may have to set off obligations arising under the Agreement and the Transaction against other obligations between the parties, whether arising under any other agreement, applicable law or otherwise.

(l)Alternative Calculations and Payment on Early Termination and on Certain Extraordinary Events. If (a) an Early Termination Date (whether as a result of an Event of Default or a Termination Event) occurs or is designated with respect to the Transaction or (b) the Transaction is cancelled or terminated upon the occurrence of an Extraordinary Event (except as a result of (i) a Nationalization, Insolvency or Merger Event in which the consideration to be paid to holders of Shares consists solely of cash, (ii) an Announcement Event, Merger Event or Tender Offer that is within Counterparty’s control, or (iii) an Event of Default in which Counterparty is the Defaulting Party or a Termination Event in which Counterparty is the Affected Party other than an Event of Default of the type described in Section 5(a)(iii), (v), (vi), (vii) or (viii) of the Agreement or a Termination Event of the type described in Section 5(b) of the Agreement, in each case that resulted from an event or events outside Counterparty’s control), and if Dealer would owe any amount to Counterparty pursuant to Section 6(d)(ii) of the Agreement or any Cancellation Amount pursuant to Article 12 of the Equity Definitions (any such amount, a “Payment Obligation”), then Dealer shall satisfy the Payment Obligation by the Share Termination Alternative (as defined below), unless (a) Counterparty gives irrevocable telephonic notice to Dealer, confirmed in writing within one Scheduled Trading Day, no later than 12:00 p.m. (New York City time) on the date of the Announcement Event, Merger Date, Tender Offer Date, Announcement Date (in the case of a Nationalization, Insolvency or Delisting), Early Termination Date or date of cancellation, as applicable, of its election that the Share Termination Alternative shall not apply, (b) Counterparty remakes the representation set forth in Section ‎8(f) as of the date of such election and (c) Dealer agrees, in its commercially reasonable discretion, to such election, in which case the provisions of Section 12.7 or Section 12.9 of the Equity Definitions, or the provisions of Section 6(d)(ii) of the Agreement, as the case may be, shall apply.

Share Termination Alternative: If applicable, Dealer shall deliver to Counterparty the Share Termination Delivery Property on, or within a commercially reasonable period of time after, the date when the relevant Payment Obligation would otherwise be due pursuant to Section 12.7 or 12.9 of the Equity Definitions or Section 6(d)(ii) and 6(e) of the Agreement, as applicable, in satisfaction of such Payment Obligation in the manner reasonably requested by Counterparty free of payment.

Share Termination Delivery Property: A number of Share Termination Delivery Units, as calculated by the Calculation Agent, equal to the Payment Obligation divided by the Share Termination Unit Price. The Calculation Agent shall adjust the Share Termination Delivery Property by replacing any fractional portion of a security therein with an amount of cash equal to the value of such fractional security based on the values used to calculate the Share Termination Unit Price.

27

Exhibit 10.1

Share Termination Unit Price: The value to Dealer of property contained in one Share Termination Delivery Unit, as determined by the Calculation Agent in its discretion by commercially reasonable means and notified by the Calculation Agent to Dealer at the time of notification of the Payment Obligation. For the avoidance of doubt, the parties agree that in determining the Share Termination Delivery Unit Price the Calculation Agent may consider the purchase price paid in connection with the purchase of Share Termination Delivery Property.

Share Termination Delivery Unit: One Share or, if the Shares have changed into cash or any other property or the right to receive cash or any other property as the result of a Nationalization, Insolvency or Merger Event (any such cash or other property, the “Exchange Property”), a unit consisting of the type and amount of such Exchange Property received by a holder of one Share (without consideration of any requirement to pay cash or other consideration in lieu of fractional amounts of any securities) in such Nationalization, Insolvency or Merger Event, as determined by the Calculation Agent.

Failure to Deliver: Applicable

Other Applicable Provisions: If Share Termination Alternative is applicable, the provisions of Sections 9.8, 9.9 and 9.11 (as modified above) of the Equity Definitions and the provisions set forth opposite the caption “Representation and Agreement” in Section 2 will be applicable, except that all references in such provisions to “Physically-settled” shall be read as references to “Share Termination Settled” and all references to “Shares” shall be read as references to “Share Termination Delivery Units”. “Share Termination Settled” in relation to the Transaction means that Share Termination Alternative is applicable to the Transaction.

(m)Waiver of Jury Trial. Each party waives, to the fullest extent permitted by applicable law, any right it may have to a trial by jury in respect of any suit, action or proceeding relating to the Transaction. Each party (i) certifies that no representative, agent or attorney of either party has represented, expressly or otherwise, that such other party would not, in the event of such a suit, action or proceeding, seek to enforce the foregoing waiver and (ii) acknowledges that it and the other party have been induced to enter into the Transaction, as applicable, by, among other things, the mutual waivers and certifications provided herein.

(n)Registration. Counterparty hereby agrees that if, in the good faith reasonable judgment of Dealer, based on advice of counsel, the Shares (“Hedge Shares”) acquired by Dealer for the purpose of hedging its obligations pursuant to the Transaction cannot be sold in the public market by Dealer without registration under the Securities Act, Counterparty shall, at its election, either (i) in order to allow Dealer to sell the Hedge Shares in a registered offering, make available to Dealer an effective registration statement under the Securities Act and enter into an agreement, in form and substance reasonably satisfactory to Dealer, substantially in the form of an underwriting agreement for a registered secondary offering by an issuer of comparable size in the same or in a similar industry;

28

Exhibit 10.1

provided, however, that if Dealer, in its sole reasonable discretion, is not satisfied with access to due diligence materials, the results of its due diligence investigation, or the procedures and documentation for the registered offering referred to above, then clause (ii) or clause (iii) of this paragraph shall apply at the election of Counterparty, (ii) in order to allow Dealer to sell the Hedge Shares in a private placement, enter into a private placement agreement substantially similar to private placement purchase agreements customary for private placements of equity securities by an issuer of comparable size in the same or in a similar industry, in form and substance reasonably satisfactory to Dealer (in which case, the Calculation Agent shall make any adjustments to the terms of the Transaction that are necessary, in its commercially reasonable judgment, to compensate Dealer for any discount from the public market price of the Shares incurred on the sale of Hedge Shares in a private placement), or (iii) purchase the Hedge Shares from Dealer at the then-current market price on such Exchange Business Days, and in the amounts and at such time(s), requested by Dealer.

(o)Tax Disclosure. Effective from the date of commencement of discussions concerning the Transaction, Counterparty and each of its employees, representatives, or other agents may disclose to any and all persons, without limitation of any kind, the tax treatment and tax structure of the Transaction and all materials of any kind (including opinions or other tax analyses) that are provided to Counterparty relating to such tax treatment and tax structure.

(p)Right to Extend. Dealer may postpone or add, in whole or in part, any Valid Day or Valid Days during the Settlement Averaging Period or any other date of valuation, payment or delivery by Dealer, with respect to some or all of the Options hereunder, if Dealer reasonably determines, in its commercially reasonable judgment (in the case of clause (i) below) or based on the advice of counsel (in the case of clause (ii) below), that such action is reasonably necessary or appropriate (i) to preserve Dealer’s commercially reasonable hedging or hedge unwind activity hereunder in light of existing liquidity conditions or (ii) to enable Dealer to effect transactions with respect to Shares in connection with its commercially reasonable hedging, hedge unwind or settlement activity hereunder in a manner that would, if Dealer were Counterparty or an affiliated purchaser of Counterparty, be in compliance with applicable legal, regulatory or self-regulatory requirements, or with related policies and procedures applicable to Dealer; provided that such policies and procedures have been adopted by Dealer in good faith and are generally applicable in similar situations and applied in a non-discriminatory manner; provided, further that no such Valid Day or any other date of valuation, payment or delivery may be postponed or added more than 100 Valid Days after the original Valid Day or any other date of valuation, payment or delivery, as the case may be.

(q)Status of Claims in Bankruptcy. Dealer acknowledges and agrees that this Confirmation is not intended to convey to Dealer rights against Counterparty with respect to the Transaction that are senior to the claims of common stockholders of Counterparty in any United States bankruptcy proceedings of Counterparty; provided that nothing herein shall limit or shall be deemed to limit Dealer’s right to pursue remedies in the event of a breach by Counterparty of its obligations and agreements with respect to the Transaction; provided, further that nothing herein shall limit or shall be deemed to limit Dealer’s rights in respect of any transactions other than the Transaction.

(r)Securities Contract; Swap Agreement. The parties hereto intend for (i) the Transaction to be a “securities contract” and a “swap agreement” as defined in the Bankruptcy Code, and the parties hereto to be entitled to the protections afforded by, among other Sections, Sections 362(b)(6), 362(b)(17), 546(e), 546(g), 555 and 560 of the Bankruptcy Code, (ii) a party’s right to liquidate the Transaction and to exercise any other remedies upon the occurrence of any Event of Default under the Agreement with respect to the other party to constitute a “contractual right” as described in the Bankruptcy Code, and (iii) each payment and delivery of cash, securities or other property hereunder to constitute a “margin payment” or “settlement payment” and a “transfer” as defined in the Bankruptcy Code.

(s)Notice of Certain Other Events. Counterparty covenants and agrees that:

29

Exhibit 10.1

(i)Promptly as reasonably practicable following the public announcement of the results of any election by the holders of Shares with respect to the consideration due upon consummation of any Merger Event, Counterparty shall give Dealer written notice of the weighted average of the types and amounts of consideration received by holders of Shares upon consummation of such Merger Event (the date of such notification, the “Consideration Notification Date”); provided that in no event shall the Consideration Notification Date be later than the date on which such Merger Event is consummated; and

(ii)(A) Counterparty shall give Dealer commercially reasonable advance (but in no event less than one Exchange Business Day) written notice of the section or sections of the Indenture and, if applicable, the formula therein, pursuant to which any adjustment will be made to the Convertible Notes in connection with any Potential Adjustment Event, Merger Event or Tender Offer and (B) promptly following any such adjustment, Counterparty shall give Dealer written notice of the details of such adjustment.

(t)Wall Street Transparency and Accountability Act.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Presentation and Principles of Consolidation

2.Basis of Presentation and Principles of Consolidation

The accompanying unaudited consolidated financial statements and related notes of the Company have been prepared in accordance with generally accepted accounting principles in the United States of America ("GAAP") and pursuant to the interim period reporting requirements of Form 10-Q. They do not include all of the information and footnotes required by GAAP for complete financial statements and, therefore, should be read in conjunction with our consolidated financial statements and the notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023.

In the opinion of management, the consolidated financial statements reflect all normal recurring adjustments necessary for a fair statement of the financial position, results of operations and cash flows for the interim periods presented. The results of operations and cash flows for any interim period are not necessarily indicative of results for the full year or for future years.

This Quarterly Report on Form 10-Q includes the accounts of Parsons Corporation and its subsidiaries and affiliates which it controls. Interests in joint ventures that are controlled by the Company, or for which the Company is otherwise deemed to be the primary beneficiary, are consolidated. For joint ventures in which the Company does not have a controlling interest, but exerts a significant influence, the Company applies the equity method of accounting (see “Note 14 – Investments in and Advances to Joint Ventures" for further discussion). Intercompany accounts and transactions are eliminated in consolidation. Certain amounts may not foot due to rounding.

Use of Estimates

The preparation of the consolidated financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual amounts could differ from those estimates. The Company’s most significant estimates and judgments involve revenue recognition with respect to the determination of the costs to complete contracts and transaction price; determination of self-insurance reserves; useful lives of property and equipment and intangible assets; valuation of deferred income tax assets and uncertain tax positions, among others. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Critical Accounting Policies and Estimates” and “Note 2—Summary of Significant Accounting Policies” in the notes to our consolidated financial statements included in the Company’s Form 10-K for the year ended December 31, 2023, for a discussion of the significant estimates and assumptions affecting our consolidated financial statements. Estimates of costs to complete contracts are continually evaluated as work progresses and are revised when necessary. When a change in estimate is determined to have an impact on contract profit, the Company records a positive or negative adjustment to the consolidated statement of income.

Acquisitions

4.Acquisitions

I.S. Engineers, LLC

On October 31, 2023, the Company entered into a Membership Interest Purchase Agreement to acquired a 100% ownership interest in I.S. Engineers, LLC (“I.S. Engineers”), a privately-owned company, for $12.2 million in cash. Headquartered in Texas, I.S. Engineers provides full service consulting specializing in transportation engineering, including roads and highways, and program management. The acquisition was entirely funded by cash on-hand. In connection with this acquisition, the Company recognized $0.3 million of acquisition related “Selling, general and administrative expense” in the consolidated statements of income for the year ended December 31, 2023, including legal fees, consulting fees, and other miscellaneous direct expenses associated with the acquisition. The Company allocated the purchase price to the appropriate classes of tangible assets and liabilities and assigned the excess of $11.9 million entirely to goodwill. The entire value of goodwill was assigned to the Critical Infrastructure reporting unit and represents synergies expected to be realized from this business combination. No goodwill is deductible for income tax purposes.

Sealing Technologies, Inc.

On August 23, 2023, the Company acquired a 100% ownership interest in Sealing Technologies, Inc (“SealingTech”), a privately-owned company, for $179.3 million in cash and up to an additional $25 million in the event an earn out revenue target is exceeded. The Company borrowed $175 million under the Credit Agreement to fund the acquisition. Headquartered in Maryland, SealingTech expands Parsons’ customer base across the Department of Defense and Intelligence Community, and further enhances the company’s capabilities in defensive cyber operations; integrated mission-solutions powered by artificial intelligence (AI) and machine learning (ML); edge computing and edge access modernization; critical infrastructure protection; and secure data management. In connection with this acquisition, the Company recognized $3.3 million of acquisition-related expenses in “Selling, general and administrative expense” in the consolidated statements of income for the year ended December 31, 2023, including legal fees, consulting fees, and other miscellaneous direct expenses associated with the acquisition.

The Company has agreed to pay the selling shareholders up to an additional $25 million in the event an earn out revenue target of $110 million is exceeded during the fiscal year ended December 31, 2024. The earn out payment due and payable by the Company to the selling shareholders shall be equal to (i) five-tenths (0.5), multiplied by (ii) the difference of (A) the actual earn out revenue minus (B) the earn out revenue target; provided, however, that in no event shall the earn out payment exceed $25 million. In the event that the earn out revenue is less than or equal to the earn out revenue target, the earn out payment shall be zero. The earn out payment, if any, shall be paid by the Company to the selling shareholders within 15 days following the date the earn out statement becomes final and binding on both parties. The fair value of the earn out (contingent consideration in the table below) was calculated using a Black-Scholes model. See “Note 2—Summary of Significant Accounting Policies” in the notes to our consolidated financial statements included in the Company’s Form 10-K for the year ended December 31, 2023 for further information on how the fair value of contingent consideration is determined.

The following table summarizes the acquisition date fair value of the purchase consideration transferred (in thousands):

	Amount
Cash paid at closing	$	179,259
Fair value of contingent consideration to be achieved		3,231
Total purchase price	$	182,490

The estimated fair value of the SealingTech contingent consideration as of March 31, 2024 was $4.1 million, a $1.8 million increase from the estimated fair value as of December 31, 2023. The change in the estimated fair value was recorded to "other income (expense), net" in the consolidated financial statements.

The entire value of goodwill is deductible for tax purposes.

The amount of revenue generated by SealingTech and included within consolidated revenue is $16.9 million for the three months ended March 31, 2024. The Company has determined that the presentation of net income from the date of acquisition is impracticable due to the integration of general corporate functions upon acquisition.

Contract assets at March 31, 2024 and December 31, 2023 include $101.5 million and $109.5 million, respectively, related to net claim recoveries. For the three months ended March 31, 2024 and March 31, 2023, there were no material losses recognized related to the collectability of claims, unapproved change orders, and requests for equitable adjustment.

During the three months ended March 31, 2024 and March 31, 2023, the Company recognized revenue of $138.3 million and $78.1 million, respectively, that was included in the corresponding contract liability balances at December 31, 2023 and December 31, 2022, respectively.

The allowance for doubtful accounts was determined based on consideration of trends in actual and forecasted credit quality of clients, including delinquency and payment history, type of client, such as a government agency or commercial sector client, and general economic conditions and particular industry conditions that may affect a client’s ability to pay.

Transaction Price Allocated to the Remaining Unsatisfied Performance Obligations

The Company’s remaining unsatisfied performance obligations (“RUPO”) as of March 31, 2024 represent a measure of the total dollar value of work to be performed on contracts awarded and in-progress. The Company had $6.3 billion in RUPO as of March 31, 2024.

RUPO will increase with awards of new contracts and decrease as the Company performs work and recognizes revenue on existing contracts. Projects are included within RUPO at such time the project is awarded and agreement on contract terms has been reached. The difference between RUPO and backlog relates to unexercised option years that are included within backlog and the value of Indefinite Delivery/Indefinite Quantity (“IDIQ”) contracts included in backlog for which delivery orders have not been issued.

RUPO is comprised of: (a) original transaction price, (b) change orders for which written confirmations from our customers have been received, (c) pending change orders for which the Company expects to receive confirmations in the ordinary course of business, and (d) claim amounts that the Company has made against customers for which it has determined that it has a legal basis under existing contractual arrangements and a significant reversal of revenue is not probable, less revenue recognized to-date.

Delayed Draw Term Loan

In September 2022, the Company entered into a $350 million unsecured Delayed Draw Term Loan with an increase option of up to $150 million (the “2022 Delayed Draw Term Loan”). Proceeds of the 2022 Delayed Draw Term Loan Agreement may be used (a) to pay off in full, or partially payoff, the Company’s existing Senior Notes, (b) to prepay revolving loans outstanding under the Revolving Credit Agreement (as defined below), or (c) for working capital, capital expenditures and other lawful corporate purposes. The Company drew $350.0 million from the 2022 Delayed Draw Term Loan in November 2022. The Company incurred $0.9 million of debt issuance costs in connection with the delayed draw term loan. These costs are presented as a direct deduction from long-term debt on the face of the balance sheet. Interest expense related to the Delayed Draw Term Loan for the three months ended March 31, 2024 and March 31, 2023 were $6.0 million and $5.1 million, respectively. The amortization of debt issuance costs and interest expense is recorded in “Interest expense” on the consolidated statements of income. As of March 31, 2024 and December 31, 2023, there was $350.0 million outstanding under the Delayed Draw Term Loan.

The 2022 Delayed Draw Term Loan has a three-year maturity and permits the Company to borrow in U.S. dollars. The 2022 Delayed Draw Term Loan does not require any amortization payments by the Company. Depending on the Company’s consolidated leverage ratio (or debt rating after such time as the Company has such rating), borrowings under the 2022 Delayed Draw Term Loan Agreement will bear interest at either an adjusted Term SOFR benchmark rate plus a margin between 0.875% and 1.500% or a base rate plus a margin of between 0% and 0.500% and will initially bear interest at the middle of this range. The Company will pay a ticking fee on unused term loan commitments at a rate of 0.175% commencing with the date that is ninety (90) days after the Closing Date. Amounts outstanding under the 2022 Delayed Draw Term Loan Agreement may be prepaid at the option of the Company without premium or penalty, subject to customary breakage fees in connection with the prepayment of benchmark rate loans. The interest rates on March 31, 2024 and December 31, 2023 were 6.4% and 6.6%, respectively.

Convertible Senior Notes due 2025

In August 2020, the Company issued an aggregate $400.0 million of 0.25% Convertible Senior Notes due 2025, including the exercise of a $50.0 million initial purchasers’ option. The Company received proceeds from the issuance and sale of the Convertible Senior Notes of $389.7 million, net of $10.3 million of transaction fees and other third-party offering expenses. The Convertible Senior Notes accrue interest at a rate of 0.25% per annum, payable semi-annually on February 15 and August 15 of each year beginning on February 15, 2021, and will mature on August 15, 2025, unless earlier repurchased, redeemed or converted.

The Convertible Senior Notes are the Company’s senior unsecured obligations and will rank senior in right of payment to any of the Company’s indebtedness that is expressly subordinated in right of payment to the Notes; equal in right of payment to any of the Company’s unsecured indebtedness that is not so subordinated; effectively junior in right of payment to any of the Company’s secured indebtedness, to the extent of the value of the assets securing such indebtedness; and structurally junior to all indebtedness and other liabilities (including trade payables) of the Company’s subsidiaries

Each $1,000 of principal of the Notes will initially be convertible into 22.2913 shares of our common stock, which is equivalent to an initial conversion price of $44.86 per share, subject to adjustment upon the occurrence of specified events. On or after March 15, 2025 until the close of business on the second scheduled trading day immediately preceding the maturity date of the Convertible Senior Notes, holders may convert all or a portion of their Convertible Senior Notes, regardless of the conditions below.

Prior to the close of business on the business day immediately preceding March 15, 2025, the Notes will be convertible at the option of the holders thereof only under the following circumstances:

•during any calendar quarter commencing after the calendar quarter ending on December 31, 2021, if the last reported sale price of the Company’s common stock for at least 20 trading days, whether or not consecutive, during a period of 30 consecutive trading days ending on, and including the last trading day of the immediately preceding calendar quarter, is greater than or equal to 130% of the conversion price on each applicable trading day;

•during the five business day period after any five consecutive trading day period in which, for each trading day of that period, the trading price per $1,000 principal amount of Convertible Senior Notes for such trading day was less than 98% of the product of the last reported sale price of the Company’s common stock and the conversion rate on each such trading day;

•if the Company calls such Convertible Senior Notes for redemption; or

•upon the occurrence of specified corporate events described in the Indenture.

The Company may redeem all or any portion of the Convertible Senior Notes for cash, at its option, on or after August 21, 2023 and before the 51st scheduled trading day immediately before the maturity date at a redemption price equal to 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest, but only if the last reported sale price per share of the Company’s common stock exceeds 130% of the conversion price for a specified period of time. In addition, calling any Convertible Senior Note for redemption will constitute a Make-Whole Fundamental Change with respect to that Convertible Senior Note, in which case the conversion rate applicable to the conversion of that Convertible Senior Note will be increased in certain circumstances if it is converted after it is called for redemption.

Upon the occurrence of a fundamental change prior to the maturity date of the Convertible Senior Notes, holders of the Convertible Senior Notes may require the Company to repurchase all or a portion of the Convertible Senior Notes for cash at a price equal to 100% of the principal amount of the Convertible Senior Notes to be repurchased, plus any accrued and unpaid interest to, but excluding, the fundamental change repurchase date.

Upon conversion, the Company may settle the Convertible Senior Notes for cash, shares of the Company’s common stock, or a combination thereof, at the Company’s option. If the Company satisfies its conversion obligation solely in cash or through payment and delivery of a combination of cash and shares of the Company’s common stock, the amount of cash and shares of common stock due upon conversion will be based on a daily conversion value calculated on a proportionate basis for each trading day in a 50-trading day observation period.

The Company recognized interest expense of $3.7 million and $0.8 million for the three months ended March 31, 2024 and March 31, 2023, respectively. The net, carrying value of the Convertible Senior Notes were $115.4 million and $396.5 million as of March 31, 2024 and December 31, 2023, respectively.

See the discussion of the partial repurchase of Convertible Senior Notes due 2025 and the unwind of the related note hedge and warrants below.

Note Hedge and Warrant - Convertible Senior Notes due 2025

In connection with the sale of the Convertible Senior Notes, the Company purchased a bond hedge designed to mitigate the potential dilution from the conversion of the Convertible Senior Notes. Under the five-year term of the bond hedge, upon a conversion of the bonds, the Company will receive the number of shares of common stock equal to the remaining common stock deliverable upon conversion of the Convertible Senior Notes if the conversion value exceeds the principal amount of the Notes. The aggregate number of shares that the Company could be obligated to issue upon conversion of the Convertible Senior Notes is approximately 8.9 million shares. The cost of the convertible note hedge transactions was $55.0 million.

The cost of the convertible note hedge was partially offset by the Company’s sale of warrants to acquire approximately 8.9 million shares of the Company’s common stock. The warrants were initially exercisable at a price of at least $66.46 per share and are subject to customary adjustments upon the occurrence of certain events, such as the payment of dividends. The Company received $13.8 million in cash proceeds from the sales of these warrants.

The bond hedge and warrant transactions effectively increased the conversion price associated with the Convertible Senior Notes during the term of these transactions from 35%, or $44.86, to 100%, or $66.46, at their issuance, thereby reducing the dilutive economic effect to shareholders upon actual conversion.

The bond hedges and warrants are indexed to, and potentially settled in, shares of the Company’s common stock. The net cost of $41.2 million for the purchase of the bond hedges and sale of the warrants was recorded as a reduction to additional paid-in capital in the consolidated balance sheets.

At issuance, the Company recorded a deferred tax liability of $16.2 million related to the Convertible Senior Notes debt discount and the capitalized debt issuance costs. The Company also recorded a deferred tax asset of $16.5 million related to the convertible note hedge transactions and the tax basis of the capitalized debt issuance costs through additional paid-in capital. The deferred tax liability and deferred tax asset were included net in “Deferred tax assets” on the consolidated balance sheets. Upon adoption of ASU 2020-06, the Company reversed the deferred tax liability of $13.9 million that the Company had recorded at issuance related to the Convertible Senior Note debt discount and recorded an additional deferred tax liability of $0.4 million related to the capitalized debt issuance costs. In addition, the Company recorded a $0.9 million adjustment to the deferred tax asset through retained earnings related to the tax effect of book accretion recorded in 2020 and reversed upon adoption.

Convertible Senior Notes due 2029

In February 2024, the Company issued an aggregate $800.0 million of 2.625% Convertible Senior Notes due 2029 (the “2029 Convertible Notes”), including the exercise of a $100.0 million initial purchasers’ option in full. The Company received proceeds from the issuance and sale of the 2029 Convertible Notes of $781.1 million, net of $18.9 million of transaction fees and other third-party offering expenses. The 2029 Convertible Notes accrue interest at a rate of 2.625% per annum, payable semi-annually on March 1 and September 1 of each year beginning on September 1, 2024, and will mature on March 1, 2029, unless earlier repurchased, redeemed or converted.

The 2029 Convertible Notes are the Company’s senior unsecured obligations and will rank senior in right of payment to any of the Company’s indebtedness that is expressly subordinated in right of payment to the 2029 Convertible Notes; equal in right of payment to any of the Company’s unsecured indebtedness that is not so subordinated; effectively junior in right of payment to any of the Company’s secured indebtedness, including borrowings under the Company’s revolving credit facility and delayed draw term loan credit facility, to the extent of the value of the assets securing such indebtedness; and structurally junior to all indebtedness and other liabilities (including trade payables) of the Company’s subsidiaries.

Each $1,000 of principal of the 2029 Convertible Notes will initially be convertible into 10.6256 shares of our common stock, which is equivalent to an initial conversion price of approximately $94.11 per share, subject to adjustment upon the occurrence of specified events. On or after October 1, 2028 until the close of business on the second scheduled trading day immediately preceding the maturity date of the 2029 Convertible Notes, holders may convert all or a portion of their 2029 Convertible Notes, regardless of the conditions below.

Prior to the close of business on the business day immediately preceding October 1, 2028, the 2029 Convertible Notes will be convertible at the option of the holders thereof only under the following circumstances:

•during any calendar quarter commencing after the calendar quarter ending on June 30, 2024, if the last reported sale price of the Company’s common stock for at least 20 trading days, whether or not consecutive, during a period of 30 consecutive trading days ending on, and including the last trading day of the immediately preceding calendar quarter, is greater than or equal to 130% of the conversion price on each applicable trading day;

•during the five business day period after any ten consecutive trading day period in which, for each trading day of that period, the trading price per $1,000 principal amount of 2029 Convertible Notes for such trading day was less than 98% of the product of the last reported sale price of the Company’s common stock and the conversion rate on each such trading day;

•if the Company calls such 2029 Convertible Notes for redemption; or

•upon the occurrence of specified corporate events described in the Indenture.

The Company may redeem all or any portion of the 2029 Convertible Notes for cash, at its option, on or after March 8, 2027 and before the 51st scheduled trading day immediately before the maturity date at a redemption price equal to 100% of the principal amount of the 2029 Convertible Notes to be redeemed, plus accrued and unpaid interest, but only if the last reported sale price per share of the Company’s common stock exceeds 130% of the conversion price for a specified period of time. In addition, calling any 2029 Convertible Notes for redemption will constitute a Make-Whole Fundamental Change with respect to that 2029 Convertible Note, in which case the conversion rate applicable to the conversion of that 2029 Convertible Notes will be increased in certain circumstances if it is converted after it is called for redemption.

Upon the occurrence of a fundamental change prior to the maturity date of the 2029 Convertible Notes, holders of the 2029 Convertible Notes may require the Company to repurchase all or a portion of the 2029 Convertible Notes for cash at a price equal to 100% of the principal amount of the 2029 Convertible Notes to be repurchased, plus any accrued and unpaid interest to, but excluding, the fundamental change repurchase date.

Upon conversion, the Company will settle the principal amount of the 2029 Convertible Notes converted in cash and will settle the remainder of the consideration owed upon conversion in cash, shares of the Company’s common stock, or a combination thereof, at the Company’s option, with such amount of cash and, if applicable, shares of common stock

due upon conversion based on a daily conversion value calculated on a proportionate basis for each trading day in a 50-trading day observation period.

The Company recognized interest expense with respect to the 2029 Convertible Notes of $2.4 million for the three months ended March 31, 2024. As of March 31, 2024, the net, carrying value of the 2029 Convertible Notes was $781.5 million.

Capped Call Transactions - Convertible Senior Notes due 2029

In February 2024, in connection with the offering of the 2029 Convertible Notes, the Company entered into capped call transactions (the “Capped Call Transactions”) with certain financial institutions. The Capped Call Transactions are expected generally to reduce the potential dilution to the Company’s common stock upon any conversion of the Convertible Senior Notes due 2029 and/or offset any cash payments the Company is required to make in excess of the principal amount of any converted Convertible Senior Notes due 2029, as the case may be. If, however, the market price per share of the Company’s common stock, as measured under the terms of the Capped Call Transactions, exceeds the cap price of the Capped Call Transactions, there would nevertheless be dilution and/or there would not be an offset of such cash payments, in each case, to the extent that such market price exceeds the cap price of the Capped Call Transactions.

The cap price of the Capped Call Transactions is initially $131.7575 per share, which represents a premium of 75% over the last reported sale price of the Company’s common stock of $75.29 per share on the New York Stock Exchange on February 21, 2024, and is subject to certain adjustments under the terms of the Capped Call Transactions. The cost of $88.4 million for the Capped Call Transactions was recorded as a reduction to additional paid-in capital in the consolidated balance sheets.

At issuance, the Company recorded a deferred tax asset of $22.3 million related to the Capped Call Transactions costs through additional paid-in capital. The deferred tax asset was included in Deferred tax assets in the consolidated balance sheets.

Convertible Senior Notes due 2025 Partial Repurchase and Note Hedge and Warrants Partial Unwind

In connection with the issuance of the Convertible Senior Notes due 2029, we used $391.8 million of the net proceeds to purchase approximately $228.1 million aggregate principal amount of our Convertible Senior Notes due 2025 concurrently with the offering in separate and individually negotiated transactions. In addition, we used $103.8 million to settle the repurchase of approximately $56.5 million aggregate principal amount of our Convertible Senior Notes due 2025 in a separately negotiated transaction that settled in March 2024. We also received approximately $90.6 million in cash from the note hedge counterparties for the partial termination of the existing bond hedge relating to the Convertible Senior Notes due 2025 repurchased, net of our obligations to the counterparties in connection with the partial termination of the related warrant transactions. The tax effect of $46.2 million from the partial unwind of the existing bond hedge was recognized as a reduction in additional paid-in capital in the consolidated balance sheets. The income tax payable was included in Income taxes payable in the consolidated balance sheets.

The partial repurchase resulted in a $214.2 million loss on debt extinguishment which includes a $3.2 million charge to interest expense for the acceleration of the amortization of debt issuance costs associated with the 0.25% Convertible Senior Notes due 2025. The tax effect of the debt extinguishment, excluding the interest expense, was recognized as a discrete event to the quarter giving rise to an increase in the effective tax rate and tax benefit of $49.9 million recognized in the income statement.

Revolving Credit Facility

In June 2021, the Company entered into a $650 million unsecured revolving credit facility (the “Credit Agreement”). The Company incurred $1.9 million of costs in connection with this Credit Agreement. The 2021 Credit Agreement replaced an existing Fifth Amended and Restated Credit Agreement dated as of November 15, 2017. Under the new agreement, the Company’s revolving credit facility was increased from $550 million to $650 million. The credit facility has a five-year maturity, which may be extended up to two times for periods determined by the Company and the applicable extending lenders, and permits the Company to borrow in U.S. dollars, certain specified foreign currencies, and each other currency that may be approved in accordance with the 2021 Facility. The borrowings under the Credit Agreement bear interest at either the Term SOFR rate plus a margin between 1.0% and 1.625% or a base rate (as defined in the Credit Agreement) plus a margin of between 0% and 0.625%. The rates on March 31, 2024 and December 31, 2023 were 6.6% and 6.7%, respectively. Borrowings under this Credit Agreement are guaranteed by certain Company operating

subsidiaries. Letters of credit commitments outstanding under this agreement aggregated to $42.1 million and $43.8 million at March 31, 2024 and December 31, 2023, respectively, which reduced borrowing limits available to the Company. Interest expense related to the Credit Agreement was $0.3 million and $0.1 million for the three months ended March 31, 2024 and March 31, 2023, respectively. There were no loan amounts outstanding under the Credit Agreement at March 31, 2024.

The Credit Agreement includes various covenants, including restrictions on indebtedness, liens, acquisitions, investments or dispositions, payment of dividends and maintenance of certain financial ratios and conditions. The Company was in compliance with these covenants at March 31, 2024 and December 31, 2023.

Letters of Credit

The Company also has in place several secondary bank credit lines for issuing letters of credit, principally for foreign contracts, to support performance and completion guarantees. Letters of credit commitments outstanding under these bank lines aggregated approximately $281.0 million and $320.7 million at March 31, 2024 and December 31, 2023, respectively.

11.Income Taxes

In 2021 the Organization for Economic Co-operation and Development (OECD) announced an inclusive Framework on Base Erosion and Profit Shifting (BEPS) including Pillar Two Model Rules defining the global minimum tax, also known as the Global Anti-Base Erosion (GloBE), which aims to ensure that multinational enterprises (MNEs) pay a 15% minimum level of tax regardless of where the MNE operates. Subsequently, multiple sets of administrative guidance have been issued. Many non-US tax jurisdictions have either recently enacted legislation to adopt components of the Pillar Two Model Rules beginning in 2024 and/or have announced their plans to enact legislation in future years. At this time, we do not expect Pillar Two to result in any material impact to the Company’s income tax provision. We are continuing to evaluate the potential impact on future periods of the Pillar Two Framework, pending enactment of legislation by individual countries.

The Company’s effective tax rate was 25.9% and 24.6% for the three months ended March 31, 2024 and March 31, 2023, respectively. The increase in the effective tax rate was due primarily to a change in jurisdictional mix of earnings, the foreign-derived intangible income (FDII) deduction, and equity-based compensation, partially offset by executive compensation subject to Section 162(m). The difference between the effective tax rate and the statutory U.S. Federal income tax rate of 21% for the three months ended March 31, 2024 primarily relates to a change in jurisdictional earnings partially resulting from a loss in partially unwinding Convertible Senior Notes, the FDII deduction, equity based compensation, and untaxed income attributable to noncontrolling interests, partially offset by rate impacts related to state income taxes and foreign withholding taxes.

As of March 31, 2024, the Company’s deferred tax assets were subject to a valuation allowance of $36.1 million primarily related to foreign net operating loss carryforwards, foreign tax credit carryforwards, and capital losses that the Company has determined are not more-likely-than-not to be realized. The factors used to assess the likelihood of realization include: the past performance of the entities, forecasts of future taxable income, future reversals of existing taxable temporary differences, and available tax planning strategies that could be implemented to realize the deferred tax assets. The ability or failure to achieve the forecasted taxable income in these entities could affect the ultimate realization of deferred tax assets.

As of March 31, 2024 and December 31, 2023, the liability for income taxes associated with uncertain tax positions was $26.7 million and $25.5 million, respectively. It is reasonably possible that the Company may realize a decrease in our uncertain tax positions of approximately $7.2 million during the next 12 months as a result of concluding various tax audits and closing tax years.

Although the Company believes its reserves for its tax positions are reasonable, the final outcome of tax audits could be materially different, both favorably and unfavorably. It is reasonably possible that certain audits may conclude in the next 12 months and that the unrecognized tax benefits the Company has recorded in relation to these tax years may change compared to the liabilities recorded for these periods.

The Company is subject to certain lawsuits, claims and assessments that arise in the ordinary course of business. Additionally, the Company has been named as a defendant in lawsuits alleging personal injuries as a result of contact with asbestos products at various project sites. Management believes that any significant costs relating to these claims will be reimbursed by applicable insurance and, although there can be no assurance that these matters will be resolved favorably, management believes that the ultimate resolution of any of these claims will not have a material adverse effect on our consolidated financial position, results of operations, or cash flows. A liability is recorded when it is both probable that a loss has been incurred and the amount of loss or range of loss can be reasonably estimated. When using a range of loss estimate, the Company records the liability using the low end of the range unless some amount within the range of loss appears at that time to be a better estimate than any other amount in the range. The Company records a corresponding receivable for costs covered under its insurance policies. Management judgment is required to determine the outcome and the estimated amount of a loss related to such matters. Management believes that there are no claims or assessments outstanding which would materially affect the consolidated results of operations or the Company’s financial position.

In September 2015, a former Parsons employee filed an action in the United States District Court for the Northern District of Alabama against us as a qui tam relator on behalf of the United States (the “Relator”) alleging violation of the False Claims Act. The plaintiff alleges that, as a result of these actions, the United States paid in excess of $1 million per month between February and September 2006 that it should have paid to another contractor, plus $2.9 million to acquire vehicles for the contractor defendant to perform its security services. The lawsuit sought (i) that we cease and desist from violating the False Claims Act, (ii) monetary damages equal to three times the amount of damages that the United States has sustained because of our alleged violations, plus a civil penalty of not less than $5,500 and not more than $11,000 for each alleged violation of the False Claims Act, (iii) monetary damages equal to the maximum amount allowed pursuant to §3730(d) of the False Claims Act, and (iv) Relator’s costs for this action, including recovery of attorneys’ fees and costs incurred in the lawsuit. The United States government did not intervene in this matter as it is allowed to do so under the statute. The court heard dispositive motions in 2023, including Parsons’ motion for summary judgment. We are awaiting the court’s rulings upon such motions, which will determine whether a trial will be necessary for this matter in 2024.

On November 28, 2023, a Proposed Statement of Decision was filed with the clerk of the Superior Court of the State of California In and For the County of San Mateo proposing an award of damages in the total amount of approximately $102.5 million in favor of Parsons Transportation Group, Inc. and against Alstom Signaling Operations LLC (Alstom") (including approximately $62.5 million relating to claims assigned to Parsons pursuant to a prior settlement with the Peninsula Corridor Joint Powers Board and approximately $40 million attributable to Parsons’ contractual and indemnification claims). This proposed award relates back to a lawsuit Parsons initially filed against the Peninsula Corridor Joint Powers Board for breach of contract and wrongful termination in February 2017 (which was settled between Parsons and the Joint Powers Board in 2021) and a cross-complaint filed against Alstom Signaling Operations LLC in November 2017, as subsequently amended, for breach of contract, negligence and intentional misrepresentation. Alstom filed objections to the Proposed Statement of Decision, and Parsons has filed its responses to the objections. The Court has scheduled a hearing upon the Objections and post-trial motions filed by Alstom in the second quarter of 2024.

At this time, the Company is unable to determine the probability of the outcome of the litigation.

Federal government contracts are subject to audits, which are performed for the most part by the Defense Contract Audit Agency (“DCAA”). Audits by the DCAA and other agencies consist of reviews of our overhead rates, operating systems and cost proposals to ensure that we account for such costs in accordance with the Cost Accounting Standards (“CAS”). If the DCAA determines we have not accounted for such costs in accordance with the CAS, the DCAA may disallow these costs. The disallowance of such costs may result in a reduction of revenue and additional liability for the Company. Historically, the Company has not experienced any material disallowed costs as a result of government audits. However, the Company can provide no assurance that the DCAA or other government audits will not result in

material disallowances for incurred costs in the future. All audits of costs incurred on work performed through 2018 have been closed, and years thereafter remain open.

Although there can be no assurance that these matters will be resolved favorably, management believes that their ultimate resolution will not have a material adverse impact on the Company’s consolidated financial position, results of operations, or cash flows.

Retirement Benefits [Abstract]

Retirement Benefit Plan

13.Retirement Benefit Plan

The Company’s principal retirement benefit plan is the Parsons Employee Stock Ownership Plan (“ESOP”), a stock bonus plan, established in 1975 to cover eligible employees of the Company and certain affiliated companies. Contributions of treasury stock to the ESOP are made annually in amounts determined by the Company’s board of directors and are held in trust for the sole benefit of the participants. Shares allocated to a participant’s account are fully vested after three years of credited service, or in the event(s) of reaching age 65, death or disability while an active employee of the Company. As of March 31, 2024 and December 31, 2023, total shares of the Company’s common stock outstanding were 106,203,479 and 105,839,978, respectively, of which 57,998,295 and 59,879,857, respectively, were held by the ESOP.

A participant’s interest in their ESOP account is redeemable upon certain events, including retirement, death, termination due to permanent disability, a severe financial hardship following termination of employment, certain conflicts of interest following termination of employment, or the exercise of diversification rights. Distributions from the ESOP of participants’ interests are made in the Company’s common stock based on quoted prices of a share of the Company’s common stock on the NYSE. A participant will be able to sell such shares of common stock in the market, subject to any requirements of the federal securities laws.

Total ESOP contribution expense was $15.0 million and $14.4 million for the three months ended March 31, 2024 and March 31, 2023, respectively. The expense is recorded in “Direct costs of contracts” and “Selling, general and administrative expense” in the consolidated statements of income. The fiscal 2024 ESOP contribution has not yet been made. The amount is currently included in accrued liabilities.

Equity Method Investments and Joint Ventures [Abstract]

Investments in and Advances to Joint Ventures

14.Investments in and Advances to Joint Ventures

The Company participates in joint ventures to bid, negotiate and complete specific projects. The Company is required to consolidate these joint ventures if it holds the majority voting interest or if the Company meets the criteria under the consolidation model, as described below.

The Company performs an analysis to determine whether its variable interests give the Company a controlling financial interest in a Variable Interest Entity (“VIE”) for which the Company is the primary beneficiary and should, therefore, be consolidated. Such analysis requires the Company to assess whether it has the power to direct the activities of the VIE and the obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIE.

The Company analyzed all of its joint ventures and classified them into two groups: (1) joint ventures that must be consolidated because they are either not VIEs and the Company holds the majority voting interest, or because they are VIEs and the Company is the primary beneficiary; and (2) joint ventures that do not need to be consolidated because they are either not VIEs and the Company holds a minority voting interest, or because they are VIEs and the Company is not the primary beneficiary.

Many of the Company’s joint venture agreements provide for capital calls to fund operations, as necessary; however, such funding is infrequent and is not anticipated to be material.

Letters of credit outstanding described in “Note 10 – Debt and Credit Facilities” that relate to project ventures are $149.9 million and $147.7 million at March 31, 2024 and December 31, 2023.

In the table below, aggregated financial information relating to the Company’s joint ventures is provided because their nature, risk and reward characteristics are similar. None of the Company’s current joint ventures that meet the characteristics of a VIE are individually significant to the consolidated financial statements.

Unconsolidated Joint Ventures

The Company accounts for its unconsolidated joint ventures using the equity method of accounting. Under this method, the Company recognizes its proportionate share of the net earnings of these joint ventures as “Equity in (losses) earnings of unconsolidated joint ventures” in the consolidated statements of income. The Company’s maximum exposure to loss as a result of its investments in unconsolidated joint ventures is typically limited to the aggregate of the carrying value of the investment and future funding commitments.

Fair Value of Financial Instruments

Fair Value Disclosures [Abstract]

Fair Value of Financial Instruments

16.Fair Value of Financial Instruments

The authoritative guidance on fair value measurement defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (referred to as an “exit price”). At March 31, 2024 and December 31, 2023, the Company’s financial instruments include cash, cash equivalents, accounts receivable, accounts payable, and other liabilities. The fair values of these financial instruments approximate their carrying values due to their short-term maturities.

Investments measured at fair value are based on one or more of the following three valuation techniques:

•Market approach—Prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities;

•Cost approach—Amount that would be required to replace the service capacity of an asset (i.e., replacement cost); and

•Income approach—Techniques to convert future amounts to a single present amount based on market expectations (including present value techniques, option-pricing models and lattice models).

In addition, the guidance establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted market prices in active markets for identical assets and liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are:

Level 1 Unadjusted quoted prices in active markets that are accessible at the measurement date for identical assets and liabilities;

Level 2 Pricing inputs that include quoted prices for similar assets and liabilities in active markets and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the instrument; and

Level 3 Prices or valuations that require inputs that are both significant to the fair value measurements and unobservable.

The methods described above may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. Furthermore, while the Company believes its valuation methods are appropriate

and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date.

Financial assets and liabilities measured at fair value on a quarterly basis are as follows:

Fair value as of March 31, 2024 (in thousands):

Earnings Per Share

Earnings Per Share [Abstract]

Earnings Per Share

17.Earnings Per Share

Basic earnings per share (“EPS”) is computed using the weighted average number of shares outstanding during the period and income available to shareholders. Diluted EPS includes additional common shares that would have been outstanding if potential common shares with a dilutive effect had been issued using the if-converted method for Convertible Debt and the treasury stock method for all other instruments.

Under the treasury stock method, the weighted average number of shares outstanding is adjusted to reflect the dilutive effects of stock-based awards.

Under the if-converted method:

1.Convertible Senior Notes due 2025:

a.Income available to shareholders is adjusted to add back interest expense, after tax (unless antidilutive).

b.Weighted average number of shares outstanding is adjusted to include the shares underlying the convertible debt (unless antidilutive).

c.Shares underlying the bond hedge (unless antidilutive).

d.Shares underlying the warrants (unless antidilutive).

2.Convertible Senior Notes due 2029:

a.Interest has been excluded from the numerator and no shares have been included in the denominator of diluted EPS, as the principal amount of convertible debt will be settled in cash with any excess conversion value settled in cash or shares of common stock.

b.Excludes shares underlying the capped call as the shares are antidilutive.

The following tables reconcile the denominator and numerator used to compute basic EPS to the denominator and numerator used to compute diluted EPS for the three months ended March 31, 2024 and March 31, 2023 (in thousands):

	Three Months Ended

Convertible senior notes if-converted method interest adjustment		-			551

Denominator for Basic and Diluted EPS:
Basic weighted average number of shares outstanding		106,037			104,805
Dilutive effect of stock-based awards		-			1,032
Dilutive effect of convertible senior notes due 2025		-			8,917

Earnings per share:
Basic	$	(1.01	)	$	0.24
Diluted	$	(1.01	)	$	0.23

Due to the loss for the three months ended March 31, 2024, stock based awards of 1.5 million shares, the potential dilution from convertible senior notes due 2025 of 6.8 million shares and convertible senior notes due 2025 interest expense of $2.8 million have been excluded from the calculation of diluted earnings per share, as their inclusion would have been antidilutive.

Anti-dilutive stock-based awards excluded from the calculation of earnings per share for the three months ended March 31, 2023 were 8,831.

Share Repurchases

On August 9, 2021, the Company’s Board of Directors authorized the Company to acquire a number of shares of Common Stock having an aggregate market value of not greater than $100 million from time to time, commencing on August 12, 2021. The Board further amended this authorization in August 2022 to remove the prior expiration date and grant executive leadership the discretion to determine the price for such share repurchases. The Board further amended this authorization in February 2024 to restore the repurchase capacity to $100 million and removed the $25 million quarterly cap on such repurchases.

At the time of the February 2024 authorization, the Company had repurchased shares with an aggregated market value (including fees) of $54.7 million. As of March 31, 2024, the Company has $100 million remaining under the stock repurchase program. The aggregate market value of shares of Common Stock the Company is authorized to acquire is now not greater than $154.7 million.

Repurchased shares of common stock are retired and included in “Repurchases of common stock” in cash flows from financing activities in the Consolidated Statements of Cash Flows. The primary purpose of the Company’s share repurchase program is to reduce the dilutive effect of shares issued under the Company’s ESOP and other stock benefit plans. The timing, amount and manner of share repurchases may depend upon market conditions and economic circumstances, availability of investment opportunities, the availability and costs of financing, the market price of the Company's common stock, other uses of capital and other factors.

There were no share repurchases during the three months ended March 31, 2024.

Segment Information

18.Segment Information

The Company operates in two reportable segments: Federal Solutions and Critical Infrastructure.

The Federal Solutions segment provides advanced technical solutions to the U.S. government, delivering timely, cost-effective hardware, software and services for mission-critical projects. The segment provides advanced technologies, supporting national security missions in cybersecurity, missile defense, and military facility modernization, logistics support, hazardous material remediation and engineering services.

The Critical Infrastructure segment provides integrated engineering and management services for complex physical and digital infrastructure around the globe. The Critical Infrastructure segment is a technology innovator focused on next generation digital systems and complex structures. Industry leading capabilities in engineering and project management allow the Company to deliver significant value to customers by employing cutting-edge technologies, improving timelines and reducing costs.

The Company defines its reportable segments based on the way the chief operating decision maker (“CODM”), its Chief Executive Officer, evaluates the performance of each segment and manages the operations of the Company for purposes of allocating resources among the segments. The CODM evaluates segment operating performance using segment Revenue and segment Adjusted EBITDA attributable to Parsons Corporation.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Presentation and Principles of Consolidation

The accompanying unaudited consolidated financial statements and related notes of the Company have been prepared in accordance with generally accepted accounting principles in the United States of America ("GAAP") and pursuant to the interim period reporting requirements of Form 10-Q. They do not include all of the information and footnotes required by GAAP for complete financial statements and, therefore, should be read in conjunction with our consolidated financial statements and the notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023.

In the opinion of management, the consolidated financial statements reflect all normal recurring adjustments necessary for a fair statement of the financial position, results of operations and cash flows for the interim periods presented. The results of operations and cash flows for any interim period are not necessarily indicative of results for the full year or for future years.

This Quarterly Report on Form 10-Q includes the accounts of Parsons Corporation and its subsidiaries and affiliates which it controls. Interests in joint ventures that are controlled by the Company, or for which the Company is otherwise deemed to be the primary beneficiary, are consolidated. For joint ventures in which the Company does not have a controlling interest, but exerts a significant influence, the Company applies the equity method of accounting (see “Note 14 – Investments in and Advances to Joint Ventures" for further discussion). Intercompany accounts and transactions are eliminated in consolidation. Certain amounts may not foot due to rounding.

Use of Estimates

Use of Estimates

The preparation of the consolidated financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual amounts could differ from those estimates. The Company’s most significant estimates and judgments involve revenue recognition with respect to the determination of the costs to complete contracts and transaction price; determination of self-insurance reserves; useful lives of property and equipment and intangible assets; valuation of deferred income tax assets and uncertain tax positions, among others. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Critical Accounting Policies and Estimates” and “Note 2—Summary of Significant Accounting Policies” in the notes to our consolidated financial statements included in the Company’s Form 10-K for the year ended December 31, 2023, for a discussion of the significant estimates and assumptions affecting our consolidated financial statements. Estimates of costs to complete contracts are continually evaluated as work progresses and are revised when necessary. When a change in estimate is determined to have an impact on contract profit, the Company records a positive or negative adjustment to the consolidated statement of income.

New Accounting Pronouncements

In the fourth quarter of 2023, The Financial Accounting Standards Board ("FASB") Issued Accounting Standards Update (“ASU”) 2023-09, "Income Taxes (Topic 740)" ("ASU 2023-09"). ASU 2023-09 enhances the transparency and decision usefulness of income tax disclosures. The amendments in ASU 2023-09 addresses investor requests for more transparency about income tax information through improvements to income tax disclosures primarily related to the rate reconciliation and income taxes paid information. ASU 2023-09 also includes certain other amendments to improve the effectiveness of income tax disclosures. ASU 2023-09 is effective for fiscal years beginning after December 15, 2024.

Early adoption is permitted. The adoption of this ASU will not have a material impact on the Company's consolidated financial statements.

In the fourth quarter of 2023, the FASB Issued ASU 2023-07, "Segment Reporting (Topic 280)". ASU 2023-07 introduces enhanced disclosures about significant segment expenses along with other enhanced segment disclosures. ASU 2023-07 is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. The adoption of this ASU will not have a material impact on the Company's consolidated financial statements.

During July 2023, the FASB Issued ASU 2023-03. ASU 2023-03 incorporates, into certain accounting standards, amendments to SEC paragraphs pursuant to SEC Staff Accounting Bulletin No. 120, SEC Staff Announcement at the March 24, 2022 EITF meeting, and Staff Accounting Bulletin Topic 6.B, Accounting Series Release 280—General Revisions of Regulation S-X: Income or Loss Applicable to Common Stock. These rules are effective immediately. The adoption of this ASU did not have a material impact on the Company's consolidated financial statements.

Leases

The Company has operating and finance leases for corporate and project office spaces, vehicles, heavy machinery and office equipment. Our leases have remaining lease terms of one year to eight years, some of which may include options to extend the leases for up to five years, and some of which may include options to terminate the leases after the third year.
