**Item 1.01 Entry into a Material Definitive Agreement**

On August 18, 2025, Centrus Energy Corp. (the "Company") issued to the several initial purchasers (the "Initial Purchasers") $805 million aggregate principal amount of the Company's 0% convertible senior notes due 2032 (the "Notes"), pursuant to a purchase agreement among the Company and BofA Securities, Inc. and J.P. Morgan Securities LLC, as representatives of the Initial Purchasers.

The Notes were offered in a private placement to persons reasonably believed to be qualified institutional buyers pursuant to Rule 144A promulgated under the Securities Act of 1933, as amended (the "Securities Act"). The offer and sale of the Notes and the shares of the Company's Class A common stock, par value $0.10 per share (the "Class A common stock"), of the Company issuable upon conversion of the Notes, if any, have not been, and will not be, registered under the Securities Act or the securities laws of any other jurisdiction, and unless so registered, the Notes and such shares, if any, may not be offered or sold in the United States except pursuant to an applicable exemption from such registration requirements. This Current Report on Form 8-K (this "Form 8-K") does not constitute an offer to sell or a solicitation of an offer to buy, nor shall there be any offer or sale of, the Notes (or any shares of Class A common stock of the Company issuable upon conversion of the Notes) in any state or jurisdiction in which the offer, solicitation, or sale would be unlawful prior to the registration or qualification thereof under the securities laws of any such state or jurisdiction.

In connection with the issuance of the Notes, the Company entered into an indenture, dated August 18, 2025 (the "Indenture"), between the Company and U.S. Bank Trust Company, National Association, as trustee (the "Trustee"). The terms of the Notes are governed by the Indenture. The Notes will not bear regular interest, and the principal amount of the notes will not accrete. Special interest will accrue on the notes in the circumstances and at the rates described in the Indenture. The Notes will mature on August 15, 2032, unless repurchased, redeemed or converted in accordance with their terms prior to such date.

The Notes are senior unsecured obligations of the Company and will rank senior in right of payment to any of the Company's unsecured indebtedness that is expressly subordinated in right of payment to the Notes; rank equal in right of payment to any of the Company's unsecured indebtedness that is not so subordinated, including the Company's 2.25% Notes due 2030; effectively rank 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 rank structurally junior to all indebtedness and other liabilities (including trade payables, but excluding intercompany obligations and liabilities of a type not required to be reflected on a balance sheet of such subsidiaries in accordance with GAAP) of the Company's existing and future subsidiaries.

The net proceeds from the offering of the Notes were approximately $782.1 million, after deducting Initial Purchasers' discounts and estimated offering expenses payable by the Company. The Company intends to use the net proceeds from the offering for general corporate purposes.

Holders may convert their Notes at their option at any time prior to the close of business on the business day immediately preceding May 15, 2032 in multiples of $1,000 principal amount, only under the following circumstances:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• during any calendar quarter commencing after the calendar quarter ending on December 31, 2025 (and only during such calendar quarter), if the last reported sale price of the Class A 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;

------

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• if the Company calls any or all of the Notes for redemption, at any time prior to the close of business on the second scheduled trading day immediately preceding the redemption date (as described in the Indenture); or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• upon the occurrence of specified corporate events.

Holders may convert their Notes, in multiples of $1,000 principal amount, at their option at any time beginning on or after May 15, 2032, and prior to the close of business on the second scheduled trading day immediately preceding the stated maturity date of the Notes, without regard to the foregoing circumstances. The initial conversion rate for the Notes is 4.3551 shares of Class A common stock per $1,000 principal amount of Notes, which is equivalent to an initial conversion price of approximately $229.62 per share of Class A common stock, subject to adjustment upon the occurrence of certain specified events as set forth in the Indenture. Upon conversion, the Company will pay cash up to the aggregate principal amount of the Notes to be converted and pay or deliver, as the case may be, cash, shares of Class A common stock or a combination of cash and shares of Class A common stock, at the Company's election, in respect of the remainder, if any, of the Company's conversion obligation in excess of the aggregate principal amount of the Notes being converted, as described in the Indenture.

In addition, upon the occurrence of a fundamental change (as defined in the Indenture), holders of the Notes may require the Company to repurchase for cash all or any portion of their Notes, in multiples of $1,000 principal amount, at a repurchase price of 100% of the principal amount of the Notes to be repurchased, *plus* any accrued and unpaid special interest, to, but excluding, the fundamental change repurchase date. If certain fundamental changes referred to as make-whole fundamental changes occur, the conversion rate for the Notes may be increased. The maximum number of shares of Class A common stock issuable per $1,000 aggregate principal amount of Notes, after the conversion rate has been increased in connection with a make-whole fundamental change or notice of redemption, is 5.3350, subject to adjustment as provided for in the Indenture.

The Notes are not redeemable prior to August 20, 2029. On or after August 20, 2029, the Company may redeem for cash all or any portion of the Notes at its option if the last reported sale price of the Class A common stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period (including the last trading day of such period) ending on, and including, the trading day immediately preceding the date on which the Company provides notice of redemption, at a redemption price equal to 100% of the principal amount of the Notes to be redeemed, *plus* any accrued and unpaid special interest to, but excluding, the redemption date.

The events of default, as set forth in the Indenture, include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• default in any payment of special interest on any Note when due and payable and the default continues for a period of 30 days;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• default in the payment of principal of any Note when due and payable at its stated maturity, upon optional redemption, upon any required repurchase, upon declaration of acceleration or otherwise;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• failure by the Company to comply with its obligation to convert the Notes in accordance with the Indenture upon exercise of a holder's conversion right and such failure continues for five (5) business days;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• failure by the Company to give a notice regarding a fundamental change, specified corporate transaction or make-whole fundamental change, in each case, when due and such failure continues for five (5) business days;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• failure by the Company to comply with its obligations under the Indenture in respect of certain merger, consolidation and asset sale transactions;

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• failure by the Company to comply with any of its other agreements contained in the provisions of the Notes or the Indenture for 60 days after receipt of written notice in accordance with the Indenture;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• default by the Company or certain of its subsidiaries with respect to indebtedness for money borrowed in excess of $60.0 million (or its foreign currency equivalent) in the aggregate of the Company and/or such subsidiaries; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• certain events of bankruptcy, insolvency or reorganization of the Company or any of the Company's significant subsidiaries.

If an event of default, other than an event of default involving certain events of bankruptcy, insolvency or reorganization of the Company or any of its significant subsidiaries, occurs and is continuing, either the Trustee or the holders of at least 25% in aggregate principal amount of the Notes then outstanding, by notice to the Company and the Trustee, may, and the trustee at the written request of such holders shall, declare 100% of the principal amount of, and accrued and unpaid special interest, if any, on, all the Notes then outstanding, to be due and payable immediately. If an event of default involving certain events of bankruptcy, insolvency or reorganization, involving the Company or any of its significant subsidiaries occurs, then 100% of the principal amount of, and all accrued and unpaid special interest, if any, on, all the Notes, will automatically become immediately due and payable without any notice or other action by the Trustee or any holder. Notwithstanding the foregoing, the Company may elect, at its option, that the sole remedy for an event of default relating to certain failures by the Company to comply with certain reporting covenants in the Indenture will consist exclusively of the right of the holders of the Notes to receive special interest on the Notes for up to 365 days following such failure.

The foregoing description of the Indenture and the Notes does not purport to be complete and is qualified in its entirety by reference to the full text of the Indenture and the form of Notes, which are attached as Exhibit 4.1 and Exhibit 4.2, respectively, to this Form 8-K and are incorporated herein by reference.

To the extent applicable, the Company and the Trustee, by their execution and delivery of this Indenture, expressly agree to such terms and provisions and to be bound thereby. In the case of any conflict between this Indenture and a Note, the provisions of this Indenture shall control and govern to the extent of such conflict. Any Global Note may be endorsed with or have incorporated in the text thereof such legends or recitals or changes not inconsistent with the provisions of this Indenture as may be required by the Custodian or the Depositary, or as may be required to comply with any applicable law or any regulation thereunder or with the rules and regulations of any securities exchange or automated quotation system upon which the Notes may be listed or traded or designated for issuance or to conform with any usage with respect thereto, or to indicate any special limitations or restrictions to which any particular Notes are subject.

Each Global Note shall represent such principal amount of the outstanding Notes as shall be specified therein and shall provide that it shall represent the aggregate principal amount of outstanding Notes from time to time endorsed thereon and that the aggregate principal amount of outstanding Notes represented thereby may from time to time be increased or reduced to reflect redemptions, repurchases, cancellations, conversions, transfers or exchanges permitted hereby.

&nbsp;&nbsp;&nbsp;&nbsp;16 (a) The Person in whose name any Note (or its Predecessor Note) is registered on the Note Register at the close of business on any Special Interest Record Date with respect to any Special Interest Payment Date shall be entitled to receive any Special Interest payable on such Special Interest Payment Date. The principal amount of any Note (x) in the case of any Physical Note, shall be payable at the corporate trust office or agency of the Company maintained by the Company for such purposes in the continental United States, which shall initially be the Corporate Trust Office and (y) in the case of any Global Note, shall be payable by wire transfer of immediately available funds to the account of the Depositary or its nominee. The Company shall pay, or cause the Paying Agent to pay, any Special Interest (i) on any Physical Notes (A) to Holders holding Physical Notes having an aggregate principal amount of $5,000,000 or less, by check mailed to the Holders of these Notes at their addresses as they appear in the Note Register and (B) to Holders holding Physical Notes having an aggregate principal amount of more than $5,000,000, either by check mailed to such a Holder or, upon written application by such a Holder to the Note Registrar not later than the relevant Special Interest Record Date, by wire transfer in immediately available funds to that Holder's account within the United States if such Holder has provided the Company, the Trustee or the Paying Agent with the requisite information necessary to make such wire transfer, which application shall remain in effect until the Holder notifies, in writing, the Note Registrar to the contrary or (ii) on any Global Note by wire transfer of immediately available funds to the account of the Depositary or its nominee. (b) Any Defaulted Amounts shall forthwith cease to be payable to the Holder on the relevant payment date and shall not accrue interest unless Special Interest was payable pursuant to this Indenture on the relevant payment date, in which case such Defaulted Amounts shall accrue interest per annum at the then-applicable Special Interest 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 any such interest thereon shall be paid by the Company, at its election in each case, as provided in clause (i) or (ii) below: (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 following manner. 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 as in this clause (i) provided. Thereupon the Company shall fix a special record date for the payment of such Defaulted Amounts which shall be not more than 15 days and not less than 10 days prior to the date of the proposed payment, and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment (unless the Trustee shall consent to an earlier date). The Company shall promptly notify the Trustee in writing of such special record date and the

------

![](projecttitan-2025convert023.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;17 Trustee, in the name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Amounts and the special record date therefor to be delivered to each Holder not less than 10 days prior to such special record date. Notice of the proposed payment of such Defaulted Amounts and the special record date therefor having been so delivered, such Defaulted Amounts shall be paid to the Persons in whose names the Notes (or their respective Predecessor Notes) are registered at the close of business on such special record date and shall no longer be payable pursuant to the following clause (ii) of this Section 2.03(c). (ii) The Company may make payment of any Defaulted Amounts in any other lawful manner not inconsistent with the requirements of any securities exchange or automated quotation system on which the Notes may be listed or designated for issuance, and upon such notice as may be required by such exchange or automated quotation system, if, after written notice given by the Company to the Trustee of the proposed payment pursuant to this clause (ii), such manner of payment shall be deemed practicable by the Trustee. (iii) The Trustee shall not at any time be under any duty or responsibility to any Holder of Notes (i) to determine the Defaulted Amounts, (ii) with respect to the nature, extent, or calculation of the amount of Defaulted Amounts owed or (iii) with respect to the method employed in such calculation of the Defaulted Amounts. (iv) For the avoidance of doubt, if any Defaulted Amounts, together, if applicable, with any interest thereon, are paid to Holders in accordance with the terms of this Indenture prior to (i) the expiration of any applicable grace period with respect to the Default in the relevant payment as set forth in Section 6.01 or (ii) the delivery of any notice of acceleration with respect to the Event of Default relating to such Default in the relevant payment, such Default or Event of Default shall be deemed cured and the Notes shall not be subject to acceleration pursuant to Section 6.02 on account of such Default or Event of Default. Section 2.04. Execution, Authentication and Delivery of Notes. The Notes shall be signed in the name and on behalf of the Company by the manual, facsimile or electronic signature of the President and Chief Executive Officer, the Chief Financial Officer, the General Counsel, the Treasurer, the Secretary, any Executive or Senior Vice President or any Vice President (whether or not designated by a number or numbers or word or words added before or after the title "Vice President"), in each case, of the Company. At any time and from time to time after the execution and delivery of this Indenture, the Company may deliver Notes executed by the Company to the Trustee for authentication, together with a Company Order for the authentication and delivery of such Notes, and the Trustee in accordance with such Company Order shall authenticate and deliver such Notes, without any further action by the Company hereunder; provided that the Trustee shall receive an Officer's Certificate and Opinion of Counsel of the Company with respect to the issuance, authentication and delivery of such Notes pursuant to Section 17.05.

------

![](projecttitan-2025convert024.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;18 Only such Notes as shall bear thereon a certificate of authentication substantially in the form set forth on the Form of Note, executed manually by an authorized signatory of the Trustee (or an authenticating agent appointed by the Trustee as provided by Section 17.10), shall be entitled to the benefits of this Indenture or be valid or obligatory for any purpose. 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. 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. The Trustee is hereby initially appointed the "Note Registrar" for the purpose of registering Notes and transfers of Notes as herein provided. The Company may appoint one or more co-Note Registrars in accordance with Section 4.02. Upon surrender for registration of transfer of any Note to the Note Registrar or any co- Note Registrar, and satisfaction of the requirements for such transfer set forth in this Section 2.05, the Company shall execute, and, upon receipt of a Company Order, the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Notes of any authorized denominations and of a like aggregate principal amount and bearing such restrictive legends as may be required by this Indenture. Notes may be exchanged for other Notes of any authorized denominations and of a like aggregate principal amount, upon surrender of the Notes to be exchanged at any such office or agency maintained by the Company pursuant to Section 4.02. Whenever any Notes are so surrendered for exchange, the Company shall execute, and, upon receipt of a Company Order, the Trustee shall authenticate and deliver, the Notes that the Holder making the exchange is entitled to receive, bearing registration numbers not contemporaneously outstanding. All Notes presented or surrendered for registration of transfer or for exchange, repurchase, redemption or conversion shall (if so required by the Company, the Trustee, the Note Registrar or any co-Note Registrar) be duly endorsed, or be accompanied by a written instrument

&nbsp;&nbsp;&nbsp;&nbsp;19 or instruments of transfer in form satisfactory to the Note Registrar and/or the Company and duly executed, by the Holder thereof or its attorney-in-fact duly authorized in writing. 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, the Trustee or the Note Registrar 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 Notes is surrendered for conversion, such portion thereof surrendered for conversion, (ii) any Notes, or a portion of any Notes, 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 Notes 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. (a) So long as the Notes are eligible for book-entry settlement with the Depositary, unless otherwise required by law, subject to the fifth 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. Each Global Note shall bear the legend required on a Global Note set forth in Exhibit A hereto. 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. (b) Every Note that bears or is required under this Section 2.05(c) to bear the legend set forth in this Section 2.05(c) (together with any Common Stock issued upon conversion of the Notes that is required to bear the legend set forth in Section 2.05(d), collectively, the "Restricted Securities") shall be subject to the restrictions on transfer set forth in this Section 2.05(c) (including those contained in the legend set forth below), unless such restrictions on transfer shall be eliminated or otherwise waived by written consent of the Company, and the Holder of each such Restricted Security, by such Holder's acceptance thereof, agrees to be bound by all such restrictions on transfer. 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.

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 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 restrictive legend set forth above and affixed on any Note will be deemed, in accordance with the terms of the certificate representing such Note, to be removed therefrom upon the Company's delivery to the Trustee of written notice to such effect, without further action by the Company, the Trustee, the Holder(s) thereof or any other Person other than as specified in Section 4.06(e); at such time, such Note will be deemed to be assigned an unrestricted CUSIP number as provided in the certificate representing such Note. 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; provided that the Depositary of any Global Note may require a mandatory exchange or other process to cause such Global Note to be identified by an unrestricted CUSIP number in the facilities of such Depositary.

![](projecttitan-2025convert028.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;22 promptly after a registration statement, if any, with respect to the Notes or any Common Stock issued upon conversion of the Notes has been declared effective under the Securities Act. 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 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 Global Notes to the Trustee such Global Notes shall be canceled. 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 in writing. 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

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 Holders (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 and the applicable rules and procedures of the Depositary. The Trustee and each agent 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.

&nbsp;&nbsp;&nbsp;&nbsp;25 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). (d) Any Note or Common Stock issued upon the conversion or exchange of a Note that is repurchased or owned by the Company or 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 the Company or 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). Any Notes resold, in accordance with this (e)Section 2.05(e), by the Company or any Affiliate of the Company (or any Person who was an Affiliate of the Company at any time during the three months immediately preceding) shall have one or more separate CUSIP numbers if any such Notes are not fungible with the Notes initially issued hereunder for U.S. federal income tax or securities law purposes. (e) 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 or have any obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this Indenture with respect to any transfer of any interest in any Note (including any transfers between or among Depositary participants or beneficial owners of interests in any Global 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. 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 its 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 and/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

------

![](projecttitan-2025convert032.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;26 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 a Company Order and of such security and/or indemnity as the Trustee, the Company and, 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, the Trustee, the Note Registrar, any co-Note Registrar or the Paying Agent 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 redemption 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 and/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 its 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

------

![](projecttitan-2025convert033.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;27 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, upon receipt of a Company Order, 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 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 may cause all Notes surrendered for the purpose of payment, repurchase, redemption, registration of transfer or exchange or conversion (other than Notes exchanged pursuant to Section 14.12), if surrendered to any Person other than the Trustee (including any of the Company's agents, Subsidiaries or Affiliates), to be surrendered to the Trustee for cancellation. All Notes so delivered to the Trustee shall be canceled promptly by it. Except for any Notes surrendered for registration of transfer or exchange, or as otherwise 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 evidence 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 Trustee shall use "CUSIP" numbers in all notices issued to Holders as a convenience to such Holders; provided that the Trustee shall have no liability for any defect in the "CUSIP" numbers as they appear on any Note, notice or elsewhere, and provided further 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, from time to time, without the consent of, or notice to, the Holders and notwithstanding Section 2.01, reopen this Indenture and issue additional Notes of the same series hereunder with the same terms as the Notes initially issued hereunder in all respects (or in all respects other than differences in the issue date, the issue price and, if applicable, the date of the first payment (if any) of Special Interest, the date from which Special Interest, if any, will accrue, the CUSIP or other securities numbers and, to the extent necessary, differences related to certain temporary securities laws restrictions) in an unlimited aggregate principal amount. Such additional Notes shall be consolidated and form a single series with the Notes initially issued hereunder; 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 one or more separate CUSIP numbers. 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,

------

![](projecttitan-2025convert034.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;28 such Officer's Certificate and Opinion of Counsel to cover such matters, in addition to those required by Section 17.05, as the Trustee shall reasonably request. 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 privately negotiated transaction or public tender or exchange offer or through counterparties to private agreements, including by cash-settled swaps or other derivatives, in each case, without the consent of, or prior notice to, the Holders of the Notes. The Company may, at its option and to the extent permitted by applicable law, reissue, resell or surrender to the Trustee for cancellation in accordance with Section 2.08 any Notes that the Company may repurchase other than Notes repurchased in connection with a Fundamental Change (and in the case of a reissuance or resale, so long as such Notes do not constitute "restricted securities" (as defined under Rule 144) upon such reissuance or resale; provided that if any such reissued Notes are not fungible with the Notes issued on the date hereof under this Indenture for U.S. federal income tax purposes, such reissued Notes shall have one or more separate CUSIP numbers). Any Notes that the Company may repurchase other than Notes repurchased in connection with a Fundamental Change shall be considered outstanding under this Indenture (except for voting purposes) unless and until such time the Company surrenders them to the Trustee for cancellation and, upon receipt of a Company Order, the Trustee shall cancel all Notes so surrendered in accordance with Section 2.08. 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 and upon the Trustee's receipt of a Company Order, shall execute such instruments reasonably requested by the Company acknowledging satisfaction and discharge of this Indenture, when (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 delivered to Holders, as applicable, after the Notes have become due and payable, whether on the Maturity Date, on any Redemption Date, on any Fundamental Change Repurchase Date, upon conversion or otherwise, cash or, solely to satisfy the Company's Conversion Obligation, cash and shares of Common Stock, if any, sufficient to pay all of the outstanding Notes and all other sums due and payable under this Indenture by the Company; and 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 Section 7.06 shall survive.

&nbsp;&nbsp;&nbsp;&nbsp;29 ARTICLE 4 PARTICULAR COVENANTS OF THE COMPANY Section 4.01. Payment of Principal and Special 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 any accrued and unpaid Special 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, redemption 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 served. 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, redemption or repurchase or for conversion and where notices and demands to or upon the Company in respect of the Notes and this Indenture may be served; provided that the Corporate Trust Office shall not be a place for service of legal process for the Company. The Company may, however, change the Paying Agent, Note Registrar or the Conversion Agent without prior notice to the Holders of the Notes, and the Company may act as the Paying Agent, Note Registrar or Conversion Agent. In acting hereunder and in connection with the Notes, the Paying Agent, Conversion Agent and Note Registrar shall act solely as an agent of the Company and the Custodian shall act solely as an agent of the Depositary and will not assume any fiduciary duty or relationship of agency or trust for or with any of the beneficial owners or Holders.

&nbsp;&nbsp;&nbsp;&nbsp;30 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. 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: (i) that it will hold all sums held by it as such agent for the payment of the principal (including the Redemption Price and the Fundamental Change Repurchase Price, if applicable) of, and any accrued and unpaid Special Interest or interest payable pursuant to Section 2.03(c) on, the Notes in trust for the benefit of the Holders of the Notes; (ii) that it will give the Trustee prompt 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 any accrued and unpaid Special Interest on, the Notes when the same shall be due and payable; and (iii) that at any time during the continuance of an Event of Default, upon request of the Trustee, it will forthwith pay to the Trustee all sums so held in trust. 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 any accrued and unpaid Special Interest on, the Notes, deposit with the Paying Agent a sum sufficient to pay such principal (including the Redemption Price and the Fundamental Change Repurchase Price, if applicable) or any such accrued and unpaid Special Interest, and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee 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 12:00 p.m., New York City time, on such date; provided that to the extent such deposit is received by the Paying Agent after 12:00 p.m., New York City time, on any such due date, such deposit shall be deemed deposited on the next Business Day. (b) If the Company shall act as its own Paying Agent, it will, on or before each due date of the principal (including the Redemption Price and the Fundamental Change Repurchase Price, if applicable) of, and any accrued and unpaid Special Interest on, the Notes, set aside, segregate and hold in trust for the benefit of the Holders of the Notes a sum sufficient to pay such principal (including the Redemption Price and the Fundamental Change Repurchase Price, if applicable) and any such accrued and unpaid Special Interest so becoming due and will promptly notify the Trustee in writing of any failure to take such action and 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, or any accrued and unpaid Special Interest on, the Notes when the same shall become due and payable.

![](projecttitan-2025convert037.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;31 (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. (d) Subject to applicable escheatment laws, any money and shares of Common Stock deposited with the Trustee, the Conversion Agent or any Paying Agent, or 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, any accrued and unpaid Special Interest or interest payable pursuant to Section 2.03(c) on and the consideration due upon conversion of any Note and remaining unclaimed for two years after such principal (including the Redemption Price and the Fundamental Change Repurchase Price, if applicable), Special Interest or interest payable pursuant to Section 2.03(c), if any, or consideration due upon conversion has become due and payable shall be paid to the Company on request of the Company contained in an Officer's Certificate, or (if then held by the Company) shall be discharged from such trust and the Trustee, the Conversion Agent or such Paying Agent, as applicable, shall have no further liability with respect to such funds and/or shares of Common Stock, as the case may be; and the Holder of such Note shall thereafter, as an unsecured general creditor, look only to the Company for payment thereof, and all liability of the Trustee, the Conversion Agent or such Paying Agent with respect to such trust money and/or shares of Common Stock, as the case may be, and all liability of the Company as trustee thereof, shall thereupon cease. (e) Upon any Event of Default pursuant to Section 6.01(h) or (i) with respect to the Company, the Trustee shall automatically be Paying Agent for the Notes. 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 legal existence. Section 4.06. Rule 144A Information Requirement and Annual Reports. 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 of the Notes 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. (a) The Company shall file with the Trustee, within 15 days after the same are required to be filed with the Commission, copies of any documents or reports that the Company is required to file with the Commission pursuant to Section 13 or 15(d) of the Exchange Act

![](projecttitan-2025convert038.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;32 (giving effect to any grace period provided by Rule 12b-25 under the Exchange Act (or any successor rule) and excluding any such information, documents or reports, or portions thereof, subject to confidential treatment and any correspondence with the Commission). Any such document or report that the Company files with the Commission via the Commission's EDGAR system (or any successor system) shall be deemed to be filed with the Trustee for purposes of this Section 4.06(b) at the time such documents are filed via the EDGAR system, it being understood that the Trustee shall have no responsibility to determine if any documents have been filed. For the avoidance of doubt, any failure to comply with this Section 4.06(b) will not constitute an Event of Default pursuant to Section 6.01(f) unless (i) the Company has received written notice from the Trustee or the Holders of at least 25% in aggregate principal amount of the Notes then outstanding of such failure and (ii) the Company has not cured such failure during the 60 consecutive days after receipt of such notice. (b) Delivery of the reports, information and documents described in subsection (b) above to the Trustee is for informational purposes only, and the Trustee's receipt of such reports, information and documents shall not constitute actual or constructive notice or knowledge of any information contained therein or determinable from information contained therein, including the Company's or any other Person's compliance with any of its covenants under this Indenture or the Notes (as to which the Trustee is entitled to conclusively rely exclusively on Officer's Certificates). The Trustee shall not be obligated to monitor or confirm, on a continuing basis or otherwise, the Company's or any other Person's compliance with the covenants under this Indenture or with respect to any reports or other documents filed under this Indenture and the Trustee shall have no liability or responsibility for the filing, timeliness or content of any such reports or other documents required under or in connection with this Indenture or the Notes. (c) If, at any time during the six-month period beginning on, and including, the date that is six months after the last date of original issuance of the 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, including but not limited to any grace period provided by Rule 12b-25 under the Exchange Act, and other than reports on Form 8-K), or the 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 the Notes), the Company shall pay Special Interest on the Notes. Such Special Interest shall accrue on the Notes at the rate of (i) 0.25% per annum of the principal amount of the 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 the Notes are not otherwise freely tradable as described above 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) 0.50% per annum of the principal amount of the Notes outstanding for each day after the first 90 days of such period for which the Company's failure to file has occurred and is continuing or the Notes are not otherwise freely tradable as described above 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 used in this Section 4.06(d), documents or reports that the Company is required to "file" with

&nbsp;&nbsp;&nbsp;&nbsp;33 the Commission pursuant to Section 13 or 15(d) of the Exchange Act does not include documents or reports that the Company furnishes to the Commission pursuant to Section 13 or 15(d) of the Exchange Act. (d) If, and for so long as, the restrictive legend on the Notes specified in Section 2.05(c) has not been, or is not deemed (as provided below) to be, removed, the Notes are assigned a restricted CUSIP number or the 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 385th day after the last date of original issuance of the Notes, the Company shall pay Special Interest on the Notes at a rate equal to (i) 0.25% per annum of the principal amount of the Notes outstanding for the first 90 days after such 385th day until the restrictive legend has been, or is deemed to have been, removed in accordance with Section 2.05(c), the Notes are assigned an unrestricted CUSIP number and the Notes are freely tradable as described above 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) 0.50% per annum of the principal amount of the Notes outstanding after the first 90 days after such 385th day until the restrictive legend on the Notes has been, or is deemed to have been, removed in accordance with Section 2.05(c), the Notes are assigned an unrestricted CUSIP number and the 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; provided, however, that no Special Interest shall accrue or be owed pursuant to this Section 4.06(e) until the fifth Business Day following written notification to the Company by the Trustee or any Holder or beneficial owner of Notes (with a copy to the Trustee) requesting that the Company comply with its obligation to pay such Special Interest (which notification may be given at any time after the 330th day after the last date of original issuance of the Notes or any additional Notes, as the case may be), it being understood and agreed that in no event shall Special Interest accrue or be owed pursuant to this Section 4.06(e) for any period prior to the 385th day after the last date of original issuance of the Notes or any additional Notes, as the case may be. The Company shall provide the Holders, the Trustee and the Paying Agent written notice of any Special Interest on or before the Special Interest Record Date immediately preceding the first relevant Special Interest Payment Date for the payment of such Special Interest. The restrictive legend on the Notes shall be deemed removed pursuant to the terms of this Indenture as provided in Section 2.05(c), and, at such time, the Notes will, pursuant to, and subject to the provisions of, such Section, be deemed assigned an unrestricted CUSIP number. However, for the avoidance of doubt, Notes other than Physical Notes will continue to bear Special Interest pursuant to this Section 4.06(e) until such time as they are identified by an unrestricted CUSIP number in the facilities of the Depositary as a result of completion of the Depositary's mandatory exchange process or otherwise. (e) Special Interest will be payable in arrears on each Special Interest Payment Date following accrual as set forth in Section 2.03(b); provided, however, that if a failure to file giving

(f) The Special 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 Special Interest that may be payable as a result of the Company's election pursuant to Section 6.03; provided that in no event shall Special Interest payable as a result of the Company's failure to timely file any document or report that the Company 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, including but not limited to any grace period provided by Rule 12b-25 under the Exchange Act, and other than reports on Form 8-K) as set forth in Section 4.06(d), together with any Special Interest payable at the Company's election pursuant to Section 6.03 for failure to comply with the Company's 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 Special Interest. (g) If Special Interest is payable by the Company pursuant to Section 4.06(d) or Section 4.06(e), the Company shall deliver to the Trustee an Officer's Certificate to that effect on or before the Special Interest Record Date immediately preceding the first relevant Special Interest Payment Date for the payment of such Special Interest stating (i) the amount of such Special Interest that is payable and (ii) the date on which such Special 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 Special Interest is payable. If the Company has paid Special 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.

------

![](projecttitan-2025convert043.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;37 (i) an involuntary case or other proceeding shall be commenced against the Company or any Significant Subsidiary seeking liquidation, reorganization or other relief with respect to the Company or such Significant Subsidiary or its respective 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 Significant Subsidiary or any substantial part of its respective property, and such involuntary case or other proceeding shall remain undismissed and unstayed for a period of 60 consecutive days. The Trustee shall not be deemed to have notice of any Default or Event of Default (other than a payment Default) unless written notice of any event which is in fact such Default or Event of Default is received by a Responsible Officer of the Trustee at the Corporate Trust Office of the Trustee and such notice references the Notes, the Company and this Indenture and such notice is described as a "Notice of Default." 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(h) or Section 6.01(i) with respect to the Company or a Significant Subsidiary), 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 (and the Trustee, at the written request of such Holders, shall) declare 100% of the principal of, and accrued and unpaid Special Interest on, all the outstanding 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(h) or Section 6.01(i) with respect to the Company or a Significant Subsidiary occurs and is continuing, 100% of the principal of, and accrued and unpaid Special 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 (or have become immediately 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 Special Interest, if any, upon all Notes and the principal of any and all Notes that shall have become due otherwise than by acceleration (with no interest accruing on such overdue principal or installments of accrued and unpaid Special Interest unless Special Interest was payable pursuant to this Indenture on the required payment date, in which case such overdue amounts shall accrue interest per annum at the then-applicable Special Interest rate borne by the Notes, to the extent that payment of such interest is enforceable under applicable law, from, and including such required payment date) 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,

![](projecttitan-2025convert044.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;38 (2) any and all existing Events of Default under this Indenture, other than the nonpayment of the principal of and accrued and unpaid Special Interest, if any, on Notes that shall have become due solely by such acceleration, shall have been cured, remedied or waived pursuant to Section 6.09 and (3) the Company has paid to the Trustee a sum sufficient to pay for all sums paid or advanced by the Trustee and the compensation and reasonable expenses, disbursements and advances of the Trustee, its agents and its counsel incurred in connection with such Default or Event of Default, 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 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 Special Interest, if any, on, any Notes, (ii) a failure to repurchase any Notes when required, (iii) a failure to pay or deliver, as the case may be, the consideration due upon conversion of the Notes or (iv) a Default or Event of Default in respect of any provision of this Indenture, the modification of which requires the consent of each Holder of a Note. For the avoidance of doubt, and without limiting the manner in which any Default can be cured: (i) a failure by the Company to provide any notice (other than a notice referred to in Section 6.01(d)) in accordance with this Indenture shall be subject to Section 6.01(f) (including the 60-day cure period contained therein), and any related Default shall be deemed cured upon the sending of such notice whether or not the events or circumstances that are the subject of such notice have already occurred at the time such notice is given; (ii) a Default by the Company in making any payment on (or delivering other consideration in respect of) any Note shall be cured upon the delivery, in accordance with the terms of this Indenture, of such payment (or other consideration) together, if applicable, with any interest thereon, and (iii) a Default that is (or, after notice or passage of time or both, would be) an Event of Default relating to the failure by the Company to comply with the Company's reporting obligations in accordance with Section 4.06(b) shall be cured upon the filing of the relevant report(s) that were required to be filed and gave rise to such Default. In addition, for the avoidance of doubt, (i) if a Default that is not an Event of Default is cured or waived before such Default would have constituted an Event of Default, then no Event of Default shall result from such Default, and (ii) if an Event of Default is cured or waived before any related notice of acceleration is delivered, such Event of Default shall be deemed cured and the Notes shall not be subject to acceleration on account of such Default. Section 6.03. Special 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 for the first 365 days after the occurrence of such an Event of Default (which, for the

![](projecttitan-2025convert045.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;39 avoidance of doubt, shall not commence until the notice described in Section 6.01(f) has been given and the related 60-day period described in Section 6.01(f) has passed) consist exclusively of the right to receive Special 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 on which such Event of Default is continuing during the 180-day period beginning on, and including, the date on which such Event of Default first occurs and (ii) 0.50% per annum of the principal amount of the Notes outstanding for each day on which such Event of Default is continuing from the 181st day until the 365th day after the occurrence of such Event of Default; provided that in no event shall Special Interest payable at the Company's election pursuant to this Section 6.03 for failure to comply with the Company's obligations set forth in Section 4.06(b), together with any Special Interest payable as a result of the Company's failure to timely file any document or report that the Company 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, including but not limited to any grace period provided by Rule 12b-25 under the Exchange Act, and other than reports on Form 8-K) as set forth in 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 Special Interest. Special Interest payable pursuant to this Section 6.03 shall be in addition to, not in lieu of, any Special Interest payable pursuant to Section 4.06(d) or Section 4.06(e). If the Company so elects, such Special Interest shall be payable as set forth in Section 2.03(b). On the 366th day after such Event of Default (if the Event of Default relating to the Company's failure to comply with its obligations as set forth in Section 4.06(d) is not cured or waived prior to such 366th day), the Notes shall be immediately subject to acceleration as provided in Section 6.02. The provisions of this Section 6.03 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 Special 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 Special Interest when due, the Notes shall be immediately subject to acceleration as provided in Section 6.02. In order to elect to pay Special Interest as the sole remedy during the first 365 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 of such election prior to the beginning of such 365-day period. Upon the failure to timely give such notice, the Notes shall be immediately subject to acceleration as provided in Section 6.02. 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 and is continuing, 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 Special Interest, if any (with no interest accruing on any overdue principal or Special Interest unless Special Interest was payable pursuant to this Indenture on the required payment date, in which case such overdue amounts shall accrue interest per annum at the then-applicable Special Interest rate borne by the Notes, subject to the enforceability thereof under applicable law, from, and including, such required payment date) and, in addition thereto, such further amount as shall be sufficient to

![](projecttitan-2025convert046.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;40 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 Special 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 and reasonable 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 in each of its capacities hereunder 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 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 in each of its capacities hereunder any amount due it for compensation and reasonable expenses, advances and disbursements, including 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 and reasonable 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.

&nbsp;&nbsp;&nbsp;&nbsp;41 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 compensation and reasonable expenses, disbursements and advances of the Trustee in each of its capacities hereunder, 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 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, upon presentation of the several Notes, and, with respect to any Physical Notes, stamping thereon the payment, if only partially paid, and upon surrender thereof, if fully paid: First, to the payment of all amounts due to the Trustee in each of its capacities hereunder and including its agents and counsel under Section 7.06; Second, in case the principal of the outstanding Notes shall not have become due and be unpaid, to the payment of any Special 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 Special Interest and cash due upon conversion, as the case may be, with interest (to the extent that any such interest is payable on such Notes and has been collected by the Trustee) upon such overdue payments at the rate of Special Interest then payable on such Notes, if any, 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, the Fundamental Change Repurchase Price and any cash due upon conversion) then owing and unpaid upon the Notes for principal and Special Interest, if any, with interest (to the extent that any such interest is payable on such Notes and has been collected by the Trustee) on the overdue principal and Special Interest, if any, at the rate of

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 any Special 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 and/or indemnity satisfactory to it against any loss, liability or expense to be incurred therein or thereby; (d) the Trustee has not complied with such request for 60 days after its receipt of such notice, request and offer of such security and/or indemnity; and (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 whatsoever 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 does

Notwithstanding any other provision of this Indenture and any provision of any Note, each Holder shall have the 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 Special 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, or to institute suit for the enforcement of any such payment or delivery, as the case may be. Section 6.07. Proceedings by Trustee. In case of an Event of Default, the Trustee may 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.

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 such direction shall not be in conflict with any rule of law or with this Indenture, the Trustee may take any other action deemed proper by the Trustee that is not inconsistent with such direction and the Trustee will be under no obligation to exercise any of the rights or powers under this Indenture at the written request or direction of any Holders unless such Holders have offered and if requested, provided to the Trustee security and/or indemnity satisfactory to the Trustee against any loss, liability or expense that might be incurred by it in compliance with such request or

&nbsp;&nbsp;&nbsp;&nbsp;44 direction. The Trustee may refuse to follow any direction that it determines is unduly prejudicial to the rights of any other Holder (it being understood that the Trustee shall have no obligation to determine if any such direction is unduly prejudicial to the rights of a Holder) or that would involve the Trustee in personal liability. 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 (including consents to such waiver obtained in connection with a repurchase of, or tender or exchange offer for, Notes) any or all existing or past Defaults or Events of Default hereunder and its consequences except (i) a continuing default in the payment of accrued and unpaid Special 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 continuing failure by the Company to pay or deliver, as the case may be, the consideration due upon conversion of the Notes or 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 a Responsible Officer of the Trustee has received written notice of the occurrence and continuance of a Default or Event of Default, or, if earlier, the Trustee otherwise is deemed to have knowledge of such Default or Event of Default, in accordance with the terms of this Indenture, deliver to all Holders notice of such Defaults and Events of Default known to a Responsible Officer of the Trustee, unless such Defaults or Events of Default shall have been cured or waived before the giving of such notice; provided that, except in the case of a Default or Event of Default in the payment of the principal of (including the Redemption Price and the Fundamental Change Repurchase Price, if applicable), or any accrued and unpaid Special Interest on, any of the Notes or a Default or Event of Default in the payment or delivery of the consideration due upon conversion, the Trustee shall be protected in withholding (but the Trustee shall not be obligated to withhold) such notice if, and so long as, it 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 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

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: (a) prior to the occurrence of an Event of Default and after the curing or waiving of all Events of Default that may have occurred: (i) the duties and obligations of the Trustee shall be determined solely by the express provisions of this Indenture, and the Trustee shall not be liable except for the performance of such duties and obligations as are specifically set forth in this Indenture and no implied covenants or obligations shall be read into this Indenture against the Trustee; and (ii) in the absence of gross negligence or willful misconduct on the part of the Trustee, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon any certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture; but, in the case of any such certificates or opinions that by any provisions hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine the same to determine whether or not they conform to the requirements of this Indenture (but need

Section 7.08. Eligibility of Trustee. There shall at all times be a Trustee hereunder which 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 7.08, 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 7.08, it shall resign immediately in the manner and with the effect hereinafter specified in this Article. Section 7.09. Resignation or Removal of Trustee. The Trustee may at any time resign by giving 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.

(a) 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 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. (b) 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 at any time 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, in which case the Trustee so removed (at the expense of the Company) 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. (c) 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 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

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.

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.

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 amending this Indenture or any supplemental indenture or the Notes; provided, however, that, without the consent of each Holder of an outstanding Note affected, no such supplemental indenture shall: (a) reduce the principal amount of Notes whose Holders must consent to an amendment;

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 deliver to the Holders 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.

The Trustee shall have no responsibility for determining whether any amendment or supplemental indenture will or may have an adverse effect on any Holder.

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 (provided that this Article 11 shall not apply to a sale, conveyance, transfer or lease of property or assets between or among the Company and its Subsidiaries), unless: (a) the resulting, surviving or transferee Person (the "Successor Company"), if not the Company, shall be a corporation organized and existing under the laws of the United States of America, any State thereof or the District of Columbia, and the Successor Company (if not the Company) shall expressly assume, by supplemental indenture all of the obligations of the Company under the Notes and this Indenture; (b) immediately after giving effect to such transaction, no Default or Event of Default shall have occurred and be continuing under this Indenture; and (c) if the Company is not the Successor Company, the Successor Company shall have delivered to the Trustee an Officer's Certificate and Opinion of Counsel in accordance with Section 11.03.

&nbsp;&nbsp;&nbsp;&nbsp;61 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 Company to Be Substituted. In case of any such consolidation, merger, sale, conveyance, transfer or lease and upon the assumption by the Successor Company, by supplemental indenture, executed and delivered to the Trustee and satisfactory in form to the Trustee, of the due and punctual payment of the principal of and interest, if any, 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 Company (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, may exercise every right and power of and 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 Company 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 which theretofore shall not have been signed by the Company and delivered to the Trustee; and, upon the written order of such Successor Company 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 Company 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. No such consolidation, merger, sale, conveyance, transfer or lease (other than any consolidation or merger where the Company is the surviving entity) shall be effective unless the Trustee shall receive an Officer's Certificate and an Opinion of Counsel as conclusive evidence, and each stating, 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, and is authorized or permitted by, the provisions of this Indenture and with such Opinion of Counsel stating that the supplemental indenture is the valid

&nbsp;&nbsp;&nbsp;&nbsp;62 and binding obligation of the Successor Company, subject to customary exceptions and qualifications. 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 any accrued and unpaid interest on 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. ARTICLE 13 [INTENTIONALLY OMITTED] ARTICLE 14 CONVERSION OF NOTES Section 14.01. Conversion Privilege. 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 $1,000 in 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 May 15, 2032 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 May 15, 2032 and prior to the close of business on the second Scheduled Trading Day immediately preceding the Maturity Date, in each case, at an initial conversion rate of 4.3551 shares of Common Stock (subject to adjustment as provided in this Article 14, the "Conversion Rate") per $1,000 in principal amount of Notes (subject to, and in accordance with, the settlement provisions of Section 14.02, the "Conversion Obligation"). (a) Prior to the close of business on the Business Day immediately preceding May 15, 2032, 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 in principal amount of Notes, as determined by the Bid Solicitation Agent 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 on each such Trading Day

------

![](projecttitan-2025convert069.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;63 and the Conversion Rate on each such Trading Day (the "Trading Price Condition"). 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 this Indenture. 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. The Bid Solicitation Agent (if other than the Company) shall have no obligation to determine the Trading Price per $1,000 in principal amount of Notes unless the Company has requested such determination, 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 in principal amount of Notes) unless Holders of at least $5,000,000 in aggregate principal amount of Notes provide the Company with a written request and reasonable evidence that the Trading Price per $1,000 in 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 in principal amount of Notes (in accordance with the procedures described above) beginning on the next Trading Day and on each successive Trading Day until the Trading Price per $1,000 in 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 to determine the Trading Price per $1,000 in principal amount of Notes when obligated as provided in the preceding sentence, or if the Company instructs the Bid Solicitation Agent 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 in 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. Any such determination shall be conclusive absent manifest error. If, at any time after the Trading Price Condition set forth above has been met, the Trading Price per $1,000 in 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 that the Trading Price Condition is no longer met and, thereafter, neither the Company nor the Bid Solicitation Agent (if other than the Company) shall be required to solicit bids pursuant to this clause (i) again until another request is made as provided for in this clause (i). The Company may replace the Bid Solicitation Agent with any Person by written notice to the Trustee and the Holders. Neither the Trustee nor the Conversion Agent shall have any duty to determine or verify the Company's determination of whether the Trading Price Condition has been met. (i) If, prior to the close of business on the Business Day immediately preceding May 15, 2032, the Company elects to:

&nbsp;&nbsp;&nbsp;&nbsp;64 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 the separation of such rights from the Common Stock) entitling them, for a period of not more than 60 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 distribute to all or substantially all holders of the Common Stock the Company's assets, securities or rights to purchase securities of the Company (other than in connection with a stockholder rights plan prior to the separation of such rights from the Common Stock), which distribution has a per share value, as reasonably determined by the Company in good faith, exceeding 10% of the Last Reported Sale Price of the Common Stock on the Trading Day 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) at least 50 Scheduled Trading Days prior to the Ex- Dividend Date for such issuance or distribution (or, if later in the case of any such separation of rights issued pursuant to a stockholder rights plan, as soon as reasonably practicable after the Company becomes aware that such separation or relevant triggering event has occurred or will occur). Once the Company has given such notice, a Holder may surrender all or any portion of its Notes 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. A Holder of the Notes may not exercise its conversion right under this Section 14.01(b)(ii) if such Holder participates, 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 such issuance or distribution without having to convert its 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. Neither the Trustee nor the Conversion Agent shall have any duty to determine or verify the Company's determination of whether an issuance or distribution described in this clause (ii) has occurred. (ii) 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 May 15, 2032, 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 consolidation, merger, binding share exchange, or transfer or lease of all or substantially all of its assets (other than a transaction that is solely for the purpose of changing the Company's jurisdiction of organization that (1) does not

The Company shall notify in writing the Holders, the Trustee and the Conversion Agent (if other than the Trustee) as promptly as practicable but in any event no later than two Business Days after the effective date of such transaction or event, as applicable. Neither the Trustee nor the Conversion Agent shall have any duty to determine or verify the Company's determination of whether a Fundamental Change or a Make-Whole Fundamental Change has occurred. (iii) Prior to the close of business on the Business Day immediately preceding May 15, 2032, 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 December 31, 2025 (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 as determined by the Company. The Company shall determine at the beginning of each calendar quarter commencing after December 31, 2025 whether the Notes may be surrendered for conversion in accordance with this clause (iv) and shall notify in writing the Holders, the Trustee and the Conversion Agent (if other than the Trustee) if the Notes become convertible in accordance with this clause (iv). Neither the Trustee nor the Conversion Agent shall have any duty to determine or verify the Company's determination of whether the condition set forth in this clause (iv) has been met. (iv) If the Company calls any or all of the Notes for redemption pursuant to Article 16, then a Holder may surrender all or any portion of its Notes for conversion at any time prior to the close of business on the second Scheduled Trading Day prior to the Redemption Date, even if the Notes are not otherwise convertible at such time. After that time, the right to convert shall expire, unless the Company defaults in the payment of the Redemption Price, in which case a Holder of Notes may convert its Notes until the date on which the Redemption Price has been paid or duly provided for.

![](projecttitan-2025convert072.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;66 (a) Subject to this Section 14.02, Section 14.03(b), Section 14.07(a) and Section 14.13, upon conversion of any Note, the Company shall pay and, if applicable, deliver, as the case may be, to the converting Holder, in respect of each $1,000 in principal amount of Notes being converted, a "Settlement Amount" equal to the sum of the Daily Settlement Amounts for each of the 40 Trading Days during the relevant Observation Period, 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. (i) All conversions for which the relevant Conversion Date occurs after the Company's issuance of a Notice of Redemption with respect to the Notes and prior to the close of business on the second Scheduled Trading Day prior to the related Redemption Date, and all conversions for which the relevant Conversion Date occurs on or after May 15, 2032, shall be settled using the same Cash Percentage. Except for any conversions for which the relevant Conversion Date occurs after the Company's issuance of a Notice of Redemption with respect to the Notes but prior to the close of business on the second Scheduled Trading Day prior to the related Redemption Date and any conversions for which the relevant Conversion Date occurs on or after May 15, 2032, the Company shall use the same Cash Percentage for all conversions with the same Conversion Date, but the Company shall not have any obligation to use the same Cash Percentage with respect to conversions with different Conversion Dates. If, in respect of any Conversion Date (or one of the periods described in the third immediately succeeding set of parentheses, as the case may be), the Company elects to settle all or a portion of its Conversion Obligation in excess of the principal amount of the Notes being converted in cash in respect of such Conversion Date (or such period, as the case may be), the Company shall inform converting Holders of such election (the "Settlement Notice") no later than the close of business on the Trading Day immediately following the related Conversion Date (or, in the case of any conversions for which the relevant Conversion Date occurs (i) after the date of issuance of a Notice of Redemption with respect to the Notes and prior to the close of business on the second Scheduled Trading Day prior to the related Redemption Date, in such Notice of Redemption or (ii) on or after May 15, 2032, no later than May 15, 2032) and the Company shall indicate in such Settlement Notice the percentage of the consideration due upon conversion in excess of the principal portion of the Notes being converted that will be paid in cash (the "Cash Percentage"). If the relevant Holders are not informed of a Cash Percentage prior to the deadline set forth in the immediately preceding sentence, the Company shall no longer have the right to elect a Cash Percentage, the Company shall be deemed to have elected a Cash Percentage of 0% and the Company shall settle its Conversion Obligation by paying cash in respect of the principal portion of the converted Notes and delivering shares of Common Stock in respect of the remainder, if any, of its Conversion Obligation in excess of the aggregate principal portion of the Notes being converted as set forth herein (subject to Section 14.02(j)). At the time that the Company informs the Holders of any election pursuant to the second immediately preceding sentence, the Company shall send a copy of the Settlement Notice to the Trustee and the Conversion Agent (if other than the Trustee). For the avoidance of doubt, failure to deliver a Settlement Notice to the Trustee or the Conversion Agent (if other than the Trustee) shall not affect the right of the Company to

(ii) For any conversion of Notes, the Daily Settlement Amounts, the Daily Net Settlement Amounts, the Daily Conversion Values and the Settlement Amount shall be determined by the Company promptly following the last day of the relevant Observation Period. Promptly after such determination of the Daily Settlement Amounts, the Daily Net Settlement Amounts, the Daily Conversion Values and the Settlement Amount, 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, the Daily Net Settlement Amounts, the Daily Conversion Values and the Settlement Amount, 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 funds equal to any Special Interest payable on the next Special Interest Payment Date to which such Holder is not entitled as set forth in Error! Reference source not found. and, if required, all transfer or similar taxes, if any, pursuant to Section 14.02(e) and (ii) in the case of a Physical Note (1) complete, manually sign and deliver an irrevocable notice to the Conversion Agent as set forth in the Form of Notice of Conversion (or a facsimile, PDF or other electronic transmission thereof) (a notice pursuant to the applicable procedures of the Depositary or a notice 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 corporate trust office of the Conversion Agent, (3) if required, furnish appropriate endorsements and transfer documents, (4) if required, pay funds equal to any Special Interest payable on the next Special Interest Payment Date to which such Holder is not entitled as set forth in Error! Reference source not found., and (5) if required, pay all transfer or similar taxes, if any, pursuant to Section 14.02(e). 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. 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

Except as set forth in Section 14.03(b) and Section 14.07(a), the Company shall pay and 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 or cause to be issued, and deliver (if applicable) to the Conversion Agent or 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, upon receipt of a Company Order, 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, the Conversion Agent 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 Conversion Agent may refuse to deliver or refuse to instruct the stock transfer agent to deliver the certificates representing the shares of Common Stock being issued in a name other than the Holder's name until the Trustee 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 or shares of Common Stock for accrued and unpaid Special Interest, if any, except as set forth below and the

------

![](projecttitan-2025convert075.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;69 Company shall not adjust the Conversion Rate for accrued and unpaid Special Interest, if any, on the Notes. 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 Special Interest, if any, to, but not including, the relevant Conversion Date. As a result, accrued and unpaid Special Interest, if any, to, but not including, the relevant Conversion Date shall be deemed to be paid in full rather than canceled, extinguished or forfeited. Upon a conversion of Notes, any accrued and unpaid Special 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 Special Interest Record Date and prior to the open of business on the corresponding Special Interest Payment Date, Holders of such Notes as of the close of business on such Special Interest Record Date will receive the full amount of any Special Interest payable on such Notes on such Special Interest Payment Date notwithstanding the conversion. Notes surrendered for conversion during the period from the close of business on any Special Interest Record Date to the open of business on the immediately following Special Interest Payment Date must be accompanied by funds equal to the amount of any Special Interest payable on the Notes so converted on the corresponding Special Interest Payment Date; provided that no such payment shall be required (1) for conversions following August 1, 2032, if Special Interest is payable on the Maturity Date; (2) if the Company has specified a Redemption Date that is after a Special Interest Record Date and on or prior to the second Scheduled Trading Day immediately following the corresponding Special Interest Payment Date; (3) if the Company has specified a Fundamental Change Repurchase Date that is after a Special Interest Record Date and on or prior to the Business Day immediately following the corresponding Special 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 on August 1, 2032 (if and to the extent Special Interest is payable on the Maturity Date), any Redemption Date described in clause (2) above or any Fundamental Change Repurchase Date described in clause (3) above shall, in each case, receive the full Special Interest payment due on the Maturity Date or the applicable Special Interest Payment Date, as the case may be, in cash regardless of whether their Notes have been converted following August 1, 2032 or such Special Interest Record Date. (i) The Person in whose name the shares of Common Stock shall be issuable upon conversion shall be treated as a stockholder of record as of the close of business on the last Trading Day of the related 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. For each Note surrendered for conversion, the full number of shares of Common Stock 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 of Common Stock remaining after such computation shall be paid in cash.

&nbsp;&nbsp;&nbsp;&nbsp;70 Section 14.03. Increased Conversion Rate Applicable to Certain Notes Surrendered in Connection with Make-Whole Fundamental Changes or a Notice of Redemption. If (x) the Effective Date of a Make-Whole Fundamental Change occurs prior to the Maturity Date or (y) the Company gives a Notice of Redemption to the Holders of the Notes with respect to any or all of the Notes in accordance with Section 16.02 and, in each case, a Holder elects to convert its Notes in connection with such Make-Whole Fundamental Change or Notice of Redemption, as the case may be, the Company shall, under the circumstances described 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 described 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 during the related Make- Whole Fundamental Change Period. A conversion of Notes shall be deemed for these purposes to be "in connection with" a Notice of Redemption if the relevant Conversion Date occurs during the period from, and including, the date of the Notice of Redemption with respect to such Notes until the close of business on the second Scheduled Trading Day immediately preceding the Redemption Date. (a) Upon surrender of Notes for conversion in connection with a Make-Whole Fundamental Change or Notice of Redemption, the Company shall satisfy the related Conversion Obligation in accordance with Section 14.02 based on the Conversion Rate as increased to reflect the Additional Shares pursuant to the table set forth in Section 14.03(e) below; provided, however, that if, at the effective time of a Make-Whole Fundamental Change described in clause (b) of the definition of Fundamental Change, the Reference Property following such Make- Whole Fundamental Change 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 in 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 will be determined and paid to Holders in cash on the second Business Day following the Conversion Date. The Company shall notify the Holders of Notes, the Trustee and the Conversion Agent (if other than the Trustee) of the Effective Date of any Make-Whole Fundamental Change no later than five Business Days after such Effective Date. If a conversion of Notes "in connection with" a Notice of Redemption shall also be deemed to be a conversion "in connection with" a Make-Whole Fundamental Change, a Holder of any such Notes to be converted shall be entitled to a single increase to the Conversion Rate with respect to the first to occur of the Effective Date of the Notice of Redemption and the Effective Date of the Make-Whole Fundamental Change, as applicable, and the later event shall be deemed not to have occurred. (b) The number of Additional Shares, if any, by which the Conversion Rate shall be increased for conversions "in connection with" a Make-Whole Fundamental Change or a Notice of Redemption 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 Notice of Redemption, 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

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 of the Notice of Redemption, as the case may be. The Company shall, in good faith, make appropriate adjustments to the Stock Price, in its good faith determination, 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 (as such term is used in Section 14.04) or expiration date of the event occurs during such five consecutive Trading Day period. (c) 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. (d) The following table sets forth the number of Additional Shares of Common Stock by which the Conversion Rate shall be increased per $1,000 in principal amount of Notes pursuant to this Section 14.03 for each Stock Price and Effective Date set forth below: Stock Price Effective Date $187.44 $200.00 $210.00 $220.00 $229.62 $250.00 $275.00 $298.50 $400.00 $500.00 $600.00 $700.00 $800.00 $1,000.00 August 18, 2025 .......... 0.9799 0.8665 0.7883 0.7189 0.6594 0.5526 0.4492 0.3726 0.1754 0.0860 0.0409 0.0175 0.0059 0.0000 August 15, 2026 .......... 0.9799 0.8665 0.7883 0.7189 0.6594 0.5526 0.4492 0.3726 0.1754 0.0860 0.0409 0.0175 0.0059 0.0000 August 15, 2027 .......... 0.9799 0.8665 0.7883 0.7189 0.6594 0.5526 0.4492 0.3726 0.1754 0.0860 0.0398 0.0163 0.0050 0.0000 August 15, 2028 .......... 0.9799 0.8665 0.7883 0.7189 0.6594 0.5526 0.4492 0.3726 0.1737 0.0781 0.0336 0.0124 0.0031 0.0000 August 15, 2029 .......... 0.9799 0.8665 0.7883 0.7189 0.6594 0.5526 0.4492 0.3726 0.1515 0.0621 0.0234 0.0069 0.0008 0.0000 August 15, 2030 .......... 0.9799 0.8665 0.7883 0.7189 0.6594 0.5526 0.4233 0.3262 0.1108 0.0374 0.0103 0.0013 0.0000 0.0000 August 15, 2031 .......... 0.9799 0.8665 0.7883 0.6863 0.5909 0.4322 0.2968 0.2101 0.0487 0.0095 0.0005 0.0000 0.0000 0.0000 August 15, 2032 .......... 0.9799 0.6449 0.4068 0.1903 0.0000 0.0000 0.0000 0.0000 0.0000 0.0000 0.0000 0.0000 0.0000 0.0000 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 above, the number of Additional Shares by which the Conversion Rate shall be increased shall be determined by a straight-line interpolation between the number of Additional Shares set forth for the

Notwithstanding the foregoing, in no event shall the Conversion Rate per $1,000 in principal amount of Notes exceed 5.3350 shares of Common Stock, subject to adjustment in the same manner as the Conversion Rate pursuant to Section 14.04 (the "Maximum Conversion Rate"). (e) 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 Holders of the Notes participate (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 their Notes, as if they 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 shares of the Common Stock, or if the Company effects a share split or share combination in respect of the Common Stock, the Conversion Rate shall be adjusted based on the following formula: 0 0 OS OS'CRCR' ×= 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;

------

![](projecttitan-2025convert079.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;73 CR' = the Conversion Rate in effect immediately after the open of business on such Ex- Dividend Date or Effective Date, as applicable; 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 any such dividend, distribution, share split or share 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 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 pursuant to a stockholder rights plan) entitling them, for a period of not more than 60 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: YOS XOSCRCR' 0 0 0 + + ×= 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

&nbsp;&nbsp;&nbsp;&nbsp;74 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 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 of the Common Stock to subscribe for or purchase shares of the Common Stock at a price per share this is 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. (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) Spin-Offs as to which the provisions set forth below in this Section 14.04(c) shall apply, (iv) except as otherwise provided in Section 14.11, rights issued pursuant to any of the Company's stockholder rights plans then in effect and (v) distributions of Reference Property in exchange for, or upon conversion of, the Common Stock in a Merger Event (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: FMVSP SPCRCR' 0 0 0 - ×=

&nbsp;&nbsp;&nbsp;&nbsp;75 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 FMV = the fair market value (as determined by the Company in good faith) 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 in principal amount thereof, at the same time and upon the same terms as holders of the Common Stock and without having to convert its Notes, 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: 0 00 0 MP MPFMVCRCR' + ×= where,

![](projecttitan-2025convert082.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;76 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 definition of Last Reported Sale Price as set forth in Section 1.01 as if references therein to Common Stock were to such Capital Stock 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 for any Trading Day that falls within the relevant Observation Period for such conversion and within the Valuation Period, the references to "10" in the preceding paragraph shall be deemed to be replaced with such lesser number of Trading Days as have elapsed from, and including, the Ex- Dividend Date of such Spin-Off to, and including, such Trading Day in determining the Conversion Rate as of such Trading Day of such Observation Period. If any dividend or distribution that constitutes a Spin-Off 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. For purposes of this Section 14.04(c) (and subject in all respects to Section 14.11), 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).

&nbsp;&nbsp;&nbsp;&nbsp;77 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 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:

![](projecttitan-2025convert084.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;78 CR' = CR0 × SP0 SP0 - C where, CR0 = the Conversion Rate in effect immediately prior to the open of business on the Ex- Dividend Date for such dividend or distribution; 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), in lieu of the foregoing increase, each Holder of a Note shall receive, for each $1,000 in principal amount of Notes, at the same time and upon the same terms as holders of shares of the Common Stock and without having to convert its Notes, 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 make a payment in respect of a tender or exchange offer for the Common Stock that is subject to then-applicable tender offer rules under the Exchange Act (other than any odd-lot tender offer), to the extent that the cash and value 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: () SP'OS OS'SP' ACCRCR' 0 0 × ×+ ×= where,

&nbsp;&nbsp;&nbsp;&nbsp;79 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; AC = the aggregate value of all cash and any other consideration (as determined by the Company in good faith) 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 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 from, and including, the Trading Day next succeeding the expiration date of such tender or exchange offer to, and including, such Trading Day in determining the Conversion Rate as of such Trading Day of such Observation Period. If the Company is obligated to purchase shares of Common Stock pursuant to any such tender or exchange offer described in Section 14.04(e) but is permanently prevented by applicable law from effecting any such purchase or all such purchases are rescinded, the applicable Conversion Rate will be readjusted to be the Conversion Rate that would then be in effect if such tender or exchange offer had not been made or had been made only in respect of the purchases that have been made. (f) 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

&nbsp;&nbsp;&nbsp;&nbsp;80 shares of the Common Stock or the right to purchase shares of the Common Stock or such convertible or exchangeable securities. (g) 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 law and the rules of The New York Stock Exchange American and any other securities 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 Company 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 The New York Stock Exchange American and any other securities 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. (h) 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 at a price per share below the Conversion Price or otherwise, other than as described in Sections 14.04 (a), (b) and (c); (ii) 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; (iii) upon the repurchase of any shares of the Common Stock pursuant to an open-market share repurchase program or other buy-back transaction, including structured or derivative transactions, that is not a tender offer or exchange offer of the kind described in Section 14.04(e); (iv) upon the issuance of any shares of Common Stock, restricted stock units or options or rights to purchase those shares pursuant to any present or future employee, director or consultant benefit plan, incentive plan or program of or assumed by the Company or any of the Company's Subsidiaries or in connection with any such shares withheld by the Company for tax withholding purposes; (v) 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 (iv) of this subsection and outstanding as of the date the Notes were first issued (other than a rights plan as described in Section 14.11); (vi) for a third-party tender offer by any party other than a tender offer by one or more of the Subsidiaries of the Company;

&nbsp;&nbsp;&nbsp;&nbsp;81 (vii) solely for a change in the par value of the Common Stock or a change in the Company's jurisdiction of incorporation; or (viii) for accrued and unpaid Special Interest, if any. (i) 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. If an adjustment to the Conversion Rate otherwise required by the provisions described above would result in a change of less than 1% to the Conversion Rate, then, notwithstanding the foregoing, the Company may, at its election by written notice to the Holders, the Trustee and the Conversion Agent (if other than the Trustee) promptly after the date such adjustment is otherwise required to be made, defer and carry forward such adjustment, except that all such deferred adjustments must be given effect immediately upon the earliest to occur of the following: (i) when all such deferred adjustments would result in an aggregate change of at least 1% to the Conversion Rate, (ii) the Conversion Date for any Notes (in the case of any conversion following a replacement of the Common Stock by Reference Property solely consisting of cash), (iii) each Trading Day of any Observation Period related to any conversion of Notes (other than as described in clause (ii)), (iv) the effective date of any Fundamental Change or the Effective Date of any Make-Whole Fundamental Change, (v) on the date the Company sends a Notice of Redemption to the Holders of the Notes for all or any of the Notes and (vi) May 15, 2032, in each case, unless the adjustment has already been made or is no longer required under this Indenture. The provisions described in the preceding sentence are referred to as the "1% Exception." (j) 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, the date on which each adjustment becomes effective and, in the case of an increase pursuant to Section 14.04(g), the period during which the adjusted Conversion Rate will be in effect 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. (k) 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.

&nbsp;&nbsp;&nbsp;&nbsp;82 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, the Daily Net Settlement Amounts 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 any conversion in connection with a Make-Whole Fundamental Change or Notice of Redemption), the Company shall, in good faith, make appropriate adjustments without duplication in respect of any adjustment made pursuant to Section 14.04 to each 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 Reported Sale Prices, the Daily VWAPs, the Daily Conversion Values, the Daily Net Settlement Amounts or the Daily Settlement Amounts are to be calculated. Section 14.06. Shares to Be Fully Paid. The Company shall provide, free from preemptive rights, out of its authorized but unissued shares or shares held in treasury, sufficient shares of Common Stock to provide for conversion of the Notes from time to time as such Notes are presented for conversion (assuming delivery upon conversion of the Notes of a number of shares of Common Stock per $1,000 in principal amount of Notes equal to the Maximum Conversion Rate). 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 or a change solely in par value), (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 "Merger Event"), then, at and after the effective time of such Merger Event, the right to convert each $1,000 in 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 Merger 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

&nbsp;&nbsp;&nbsp;&nbsp;83 share of Common Stock is entitled to receive) upon such Merger Event and, prior to or at the effective time of such Merger 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 in principal amount of Notes; provided, however, that at and after the effective time of the Merger Event, the Conversion Obligation shall be determined and conversions shall be settled in accordance with Section 14.02 such that (A) the amount otherwise payable in cash upon conversion of the Notes as set forth under Section 14.02 shall continue to be payable in cash, (B) the Company (or the successor or purchasing Person, as the case may be) shall continue to have the right to determine the form of consideration to be paid or delivered, as the case may be, in respect of the remainder, if any, of the Conversion Obligation in excess of the principal amount of the Notes being converted as set forth under Section 14.02, (C) the number of shares of Common Stock, if any, otherwise deliverable 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 received in such Merger Event and (D) the Daily VWAP shall be calculated based on the value of a unit of Reference Property that a holder of one share of Common Stock would have received in such Merger Event. If the Merger 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 weighted average of 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 consideration referred to in clause (i) attributable to one share of Common Stock. The Company shall notify in writing the 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. If the holders of the Common Stock receive only cash in such Merger Event, then for all conversions for which the relevant Conversion Date occurs after the effective date of such Merger Event (A) the consideration due upon conversion of each $1,000 in 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 Merger 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 supplemental indenture described in the second immediately preceding paragraph providing that the Notes will be convertible into Reference Property (other than cash and/or cash equivalents) shall also 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 Merger Event, the Reference Property includes shares of stock, securities or other property or assets (other than cash and/or cash equivalents) of a Person other than the Company or the successor or purchasing corporation, as the case may be, in such Merger Event, then such supplemental indenture shall also be executed by such other Person and shall contain such additional provisions to protect the interests of the Holders of the Notes as the Company shall in

&nbsp;&nbsp;&nbsp;&nbsp;84 good faith reasonably consider 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 Merger 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 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 Merger Event unless its terms are consistent with this Section 14.07. None of the foregoing provisions shall affect the right of a Holder to convert its Notes into cash and shares of Common Stock, if any, as set forth in Section 14.01 and Section 14.02 prior to the effective date of such Merger Event. (d) The provisions of this Section 14.07 shall similarly apply to successive Merger Events. Section 14.08. Certain Covenants. 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. (a) The Company 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. (b) 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 list and use commercially reasonable efforts to 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, nor shall the Trustee and any other Conversion Agent have any liability, to any Holder to calculate or 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

![](projecttitan-2025convert091.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;85 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 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 the absence of gross negligence or willful misconduct on its part, in conclusively 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). In no event shall the Trustee nor the Conversion Agent be charged with knowledge of or have any duty to monitor the Stock Price or the Measurement Period. The parties agree that all notices to the Trustee or the Conversion Agent under this Article 14 shall be in writing. Section 14.10. [Reserved]. Section 14.11. Stockholder Rights Plans. To the extent 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. When a Holder surrenders its Notes for conversion, the Company may, at its election (an "Exchange Election"), direct in writing the Conversion Agent to deliver, on or prior to the Trading Day immediately following the

------

![](projecttitan-2025convert092.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;86 Conversion Date, such Notes to one or more financial institutions designated by the Company (each, a "Designated Financial Institution") for exchange in lieu of conversion. In order to accept any Notes surrendered for conversion, the Designated Financial Institution(s) must agree to timely pay and deliver, as the case may be, in exchange for such Notes, cash up to the aggregate principal amount of converted Notes and cash, shares of Common Stock or a combination of cash and shares of Common Stock, at the Company's election, in respect of the remainder, if any, of the Conversion Obligation in excess of the aggregate principal amount of such Notes, that would otherwise be due upon conversion pursuant to Section 14.02 (the "Conversion Consideration"). If the Company makes an Exchange Election, the Company shall, by the close of business on the Trading Day immediately following the relevant Conversion Date, notify in writing the Trustee, the Conversion Agent (if other than the Trustee) and the Holder surrendering its Notes for conversion that the Company has made the Exchange Election, and the Company shall notify the Designated Financial Institution(s) of the relevant deadline for delivery of the Conversion Consideration and the relevant Cash Percentage, as the case may be. (a) Any Notes delivered to the Designated Financial Institution(s) shall remain outstanding, subject to applicable procedures of the Depositary. If the Designated Financial Institution(s) agree(s) to accept any Notes for exchange but does/do not timely pay and deliver, as the case may be, the related Conversion Consideration to the Holder surrendering any such Note for conversion, or if such Designated Financial Institution does not accept the Notes for exchange pursuant to this Section 14.12, the Company shall pay and deliver, as the case may be, the relevant Conversion Consideration as, and at the time, required pursuant to this Indenture as if the Company had not made the Exchange Election. (b) The Company's designation of any Designated Financial Institution(s) to which the Notes may be submitted for exchange does not require such Designated Financial Institution(s) to accept any Notes (unless such Designated Financial Institution(s) has/have 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. Section 14.13. Limitation on Conversions. Notwithstanding anything to the contrary in this Indenture, the Company shall not give effect to the conversion of any Notes, Holders shall not have the right to convert any Notes pursuant to the terms and conditions of this Indenture and any such conversion shall be null and void and treated as if never made, to the extent that after giving effect to such conversion, the converting Holder of, or owner of a beneficial interest in, the Notes to be converted, together with the all Affiliated Parties and Associates collectively, would Beneficially Own in excess of 4.99% (the "Maximum Percentage") of the shares of Common Stock then outstanding immediately after giving effect to such conversion (assuming that, upon conversion of Notes, the Company will deliver the full number of shares of Common Stock underlying the Notes to be converted), unless such Holder of, or owner of a beneficial interest in, the Notes to be converted has received prior approval of the Board of Directors. For purposes of determining the number of outstanding shares of Common Stock such Holder (or such owner of a beneficial interest) may acquire upon the conversion of Notes without exceeding

------

![](projecttitan-2025convert093.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;87 the Maximum Percentage, such Holder (or such owner of a beneficial interest) may rely on the number of outstanding shares of Common Stock as reflected in the most recent of (x) the Company's most recent Annual Report on Form 10-K, Quarterly Report on Form 10-Q, Current Report on Form 8-K or other public filing with the Commission, as the case may be, (y) a more recent public announcement by the Company or (z) any other written notice delivered by the Company to all Holders setting forth the number of shares of Common Stock outstanding (the "Reported Outstanding Share Number"). If the Company receives a Notice of Conversion from a Holder at a time when the actual number of outstanding shares of Common Stock is less than the Reported Outstanding Share Number, the Company shall notify such Holder in writing of the number of shares of Common Stock then outstanding and, to the extent that such Notice of Conversion would otherwise cause the Beneficial Ownership of such holder (or such owner of a beneficial interest) calculated as described above to exceed the Maximum Percentage, such Holder (or such owner of a beneficial interest) shall notify the Company of a reduced aggregate principal amount of Notes to be converted pursuant to such Notice of Conversion. For any reason at any time, upon the written request of a Holder of, or an owner of a beneficial interest in, Notes, the Company shall within one (1) Business Day confirm in writing or by electronic mail to any Holder (or owner of a beneficial interest) the number of shares of Common Stock then outstanding. No prior inability to convert Notes pursuant to this Section 14.13 shall have any effect on the applicability of the provisions of this Section 14.13 with respect to any subsequent determination of convertibility. The limitation contained in this Section 14.13 may not be waived and shall apply to all successor Holders. Neither the Trustee nor the Conversion Agent shall have any obligation to monitor whether any conversion is in compliance with the foregoing provisions or the requirements of the Exchange Act, and shall have no obligation to monitor the shares of Common Stock held or to be held by any Holder. ARTICLE 15 REPURCHASE OF NOTES AT OPTION OF HOLDERS Section 15.01. [Intentionally Omitted]. Section 15.02. Repurchase at Option of Holders Upon a Fundamental Change. If a Fundamental Change occurs at any time, each Holder shall have the right (the "Fundamental Change Repurchase Right"), at such Holder's option, to require the Company to repurchase for cash all of such Holder's Notes, or any portion of the principal amount thereof properly surrendered and not validly withdrawn pursuant to Section 15.03 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 Business Days or more than 35 Business Days following the date of the Fundamental Change Company Notice at a repurchase price equal to 100% of the principal amount thereof, plus any accrued and unpaid Special Interest thereon to, but excluding, the Fundamental Change Repurchase Date (the "Fundamental Change Repurchase Price"), unless the Fundamental Change Repurchase Date falls after a Special Interest Record Date but on or prior to the Special Interest Payment Date to which such Special Interest Record Date relates, in which case the Company shall instead pay the full amount of accrued and unpaid Special Interest to Holders of record as of such Special Interest Record Date, and the Fundamental Change Repurchase Price shall be equal to 100% of the principal amount of

![](projecttitan-2025convert094.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;88 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 as a result of changes to such applicable law occurring after the date of this Indenture. (a) Repurchases of Notes under this Section 15.02 shall be made, at the option of the Holder thereof, upon: (i) delivery to the 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 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 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 or transfer being a condition to receipt by the Holder of the Fundamental Change Repurchase Price therefor. The Fundamental Change Repurchase Notice in respect of any Physical Notes to be repurchased shall state: (i) 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 $1,000 or an integral multiple thereof; and (iii) that the Notes are to be repurchased by the Company pursuant to the applicable provisions of the Notes and this Indenture. If the Notes are Global Notes, in order to exercise the Fundamental Change Repurchase Right, Holders must surrender their Notes in accordance with applicable Depositary procedures. Notwithstanding anything herein to the contrary, any Holder exercising the Fundamental Change Repurchase Right contemplated by this Section 15.02 shall have the right to withdraw, in whole or in part, its election to exercise the Fundamental Change Repurchase Right at any time prior to the close of business on the Business Day immediately preceding the Fundamental Change Repurchase Date by, in the case of Physical Notes, delivery of a written notice of withdrawal to the Paying Agent in accordance with Section 15.03, or in accordance with the applicable procedures of the Depositary in the case of Global Notes. The Paying Agent shall promptly notify the Company of the receipt by it of any Fundamental Change Repurchase Notice or written notice of withdrawal thereof.

![](projecttitan-2025convert095.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;89 (b) On or before the 20th Business Day after (i) the date that the Company knew or reasonably should have known that the Fundamental Change occurred, in the case of a Fundamental Change described in clause (a) of the Fundamental Change definition in Section 1.01, or (ii) the date the Fundamental Change occurred, in the case of any other Fundamental Change, the Company shall provide to all Holders of Notes, the Conversion Agent (in the case of a Conversion Agent other than the Trustee) and the Trustee and the Paying Agent (in the case of a Paying Agent other than the Trustee) a written notice (the "Fundamental Change Company Notice") of the occurrence of the effective date of the Fundamental Change and of the Fundamental Change 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 as a result of a Fundamental Change; (viii) that the Notes with respect to which a Holder has elected to exercise the Fundamental Change Repurchase Right may be converted only if the Holder withdraws its election to exercise the Fundamental Change Repurchase Right in accordance with the terms of this Indenture; and (ix) the procedures that Holders must follow to require the Company to repurchase their Notes. Notwithstanding anything to the contrary above, the Company shall not be required to repurchase or make an offer to repurchase the Notes upon 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 for an offer made by the Company as set forth in this Indenture and such third party purchases all Notes properly surrendered and not validly withdrawn under its offer in the same manner, at the same time and otherwise in compliance with the requirements for an offer made by the Company as set forth in this Indenture.

![](projecttitan-2025convert096.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;90 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 written request, given at least two (2) Business Days before such notice is to be sent (or such shorter period as shall be acceptable to the Trustee), the Trustee 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.
