THIRD SUPPLEMENTAL INDENTURE, dated June 9, 2026, between Arch Capital Group Ltd., a Bermuda company limited by shares (herein called the “Company”), and The Bank of New York Mellon, a New York banking corporation, as trustee hereunder (herein called the “Trustee”).

RECITALS OF THE COMPANY

The Company and the Trustee entered into an Indenture dated as of May 4, 2004 (the “Original Indenture”), pursuant to which senior unsecured debentures, notes or other evidences of indebtedness of the Company (the “Securities”), which may be convertible into or exchangeable for any securities of any Person (including the Company), may be issued in one or more series from time to time.

Section 301 of the Original Indenture permits the terms of any series of Securities to be established in an indenture supplemental to the Original Indenture.

Section 901 of the Original Indenture provides that a supplemental indenture may be entered into by the Company and the Trustee without the consent of any Holders of the Securities for certain purposes stated therein.

The Company has requested the Trustee to join with it in the execution and delivery of this Third Supplemental Indenture in order to supplement the Original Indenture by, among other things, establishing certain terms of two series of Securities to be known as the Company’s 5.250% Senior Notes due 2036 (the “2036 Notes”) and 5.950% Senior Notes due 2056 (the “2056 Notes” and, together with the 2036 Notes, the “Notes”) and adding certain provisions thereof for the benefit of the Holders of the Notes.

The Company has furnished the Trustee with a duly authorized and executed Company Order dated the date hereof authorizing the execution of this Third Supplemental Indenture and the issuance of the Notes.

All things necessary to make this Third Supplemental Indenture a valid agreement of the Company and the Trustee and a valid supplement to the Original Indenture have been done.

NOW, THEREFORE, THIS THIRD SUPPLEMENTAL INDENTURE WITNESSETH:

For and in consideration of the premises and the purchase of the Notes to be issued hereunder by Holders thereof, the Company and the Trustee mutually covenant and agree, for the equal and proportionate benefit of the respective Holders from time to time of the Notes, as follows:

(3)a banking moratorium shall have been declared by the federal or state authorities of Bermuda, the United Kingdom, the United States, and/or any member state of the European Economic Area (the “EEA”) and such moratorium materially disrupts or otherwise has a material adverse effect on trading in, or the issuance and sale of, Qualifying Securities for the purposes of satisfying the Replacement Capital Obligation;

(7)an event occurs and is continuing as a result of which the offering document for the offer and sale of Qualifying Securities would, in the Company’s reasonable judgment, contain an untrue statement of a material fact or omit to state a material fact required to be stated in that offering document or necessary to make the statements in that offering document not misleading and either (a) the disclosure of that event at such time, in the Company’s reasonable judgment, is not otherwise required by law and would have an adverse effect on its business in any material respect, (b) the disclosure relates to a previously undisclosed proposed or pending material business transaction, the disclosure of which would impede, delay or otherwise negatively effect the Company’s ability to consummate that transaction or (c) the event relates to a previously undisclosed material (re)insurance loss and the disclosure of that event at such time, in the Company’s reasonable judgment, is impeded by the current nature of such event and the extent of losses remain under consideration by the Company’s management pending further information from brokers, cedants or insureds, provided that no single suspension period described in this item 7 shall exceed 90 consecutive days and multiple suspension periods described in this item 7 shall not exceed an aggregate of 90 days in any 180-day period; or

(8)the Company reasonably believes that the offering document for the offer and the sale of Qualifying Securities would not be in compliance with a rule or regulation of the Commission or any other securities regulatory authority or exchange to which the Company is subject (for reasons other than those described in item 7 above) and it is unable to comply with such rule or regulation or such compliance is unduly burdensome, provided that no single suspension period described in this item 8 shall exceed 90 consecutive days and multiple suspension periods described in this item 8 shall not exceed an aggregate of 90 days in any 180-day period.

“material indebtedness” means any bond, debenture, note or other evidence of indebtedness of the Company, in each case for borrowed money, in an aggregate amount exceeding $200,000,000.

(iii)Securities which have been paid pursuant to Section 307 of the Original Indenture or in exchange for or in lieu of which other Securities have been authenticated and delivered pursuant to the Indenture, other than any such Securities in respect of which there shall have been presented to the Trustee proof satisfactory to it that such Securities are held by a bona fide purchaser in whose hands such Securities are valid obligations of the Company;

provided, however, that in determining whether the Holders of the requisite principal amount of the Outstanding Securities have given any request, demand, authorization, direction, notice, consent or waiver hereunder, Securities owned by the Company or any other obligor upon the Securities or any Affiliate of the Company or of such other obligor shall be disregarded and deemed not to be Outstanding, except that, in determining whether the Trustee shall be protected in relying upon any such request, demand, authorization, direction, notice, consent or waiver, only Securities which the Responsible Officer of the Trustee actually knows to be so owned shall be so disregarded. Securities so owned which have been pledged in good faith may be regarded as Outstanding if the pledgee establishes to the satisfaction of the Trustee the pledgee’s right so to act with respect to such Securities and that the pledgee is not the Company or any other obligor upon the Securities or any Affiliate of the Company or of such other obligor. In case of a dispute as to such right, any decision by the Trustee shall be full protection to the Trustee. Upon request of the Trustee, the Company shall furnish to the Trustee promptly an Officers’ Certificate listing and identifying all Securities, 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 601 of the Original Indenture, the Trustee shall be entitled to accept such Officers’ Certificate as conclusive

evidence of the facts therein set forth and of the fact that all Securities not listed therein are Outstanding for the purposes of any such determination.

“Par Call Date” means (1) with respect to the 2036 Notes, March 15, 2036 (the “2036 Notes Par Call Date”), and (2) with respect to the 2056 Notes, December 15, 2055 (the “2056 Notes Par Call Date”).

“Qualifying Securities” means any securities (other than the Company’s common shares, rights to purchase the Company’s common shares and securities convertible into or exchangeable for the Company’s common shares, such as preference shares that are convertible into the Company’s common shares) having equal or better capital treatment as the capital represented by the Notes under the Group Supervision Rules.

“Relevant Taxing Jurisdiction” means Bermuda or any political subdivision or taxing authority thereof or therein.

“Responsible Officer,” when used with respect to the Trustee, means any officer within the corporate trust department of the Trustee, including any vice president, assistant vice president, senior associate, assistant secretary, assistant treasurer, trust officer or any other officer of the Trustee who customarily performs functions similar to those performed by the Persons who at the time shall be such officers, respectively, or to whom any corporate trust matter is referred because of such person's knowledge of and familiarity with the particular subject and who shall have direct responsibility for the administration of the Indenture.

“Tax Event” means, with respect to a series of Notes, if at any time the Company receives an opinion of counsel that as a result of (i) any change in or amendment to the laws or treaties (or any regulations or rulings promulgated under these laws or treaties) of any Relevant Taxing Jurisdiction or any change in or amendment to the application or official interpretation of such laws, treaties, regulations or rulings, (ii) any action taken by a taxing authority of any Relevant Taxing Jurisdiction, or (iii) a decision rendered by a court of competent jurisdiction in any Relevant Taxing Jurisdiction whether or not such decision was rendered with respect to the Company, in each case, which change is formally announced after the Issue Date (or, in the case of a jurisdiction that first becomes a Relevant Taxing Jurisdiction at a later date, after such date), there is a substantial probability that the Company will be required at any time thereafter to pay Additional Amounts with respect to any Notes of such series as provided in Section 5.2 of the

Indenture and such requirement cannot be avoided by the use of reasonable measures then available.

“Tier 3 Capital” means “Tier 3 Ancillary Capital” as set out in the Group Supervision Rules (or, if the Group Supervision Rules are amended so as to no longer refer to Tier 3 Ancillary Capital in this respect, the nearest corresponding concept (if any) under the Group Supervision Rules, as amended).

“Treasury Rate” means, for any Redemption Date, yield determined by the Company in accordance with the following two paragraphs.

The Treasury Rate shall be determined by the Company after 4:15 p.m., New York City time (or after such time as yields on U.S. government securities are posted daily by the Board of Governors of the Federal Reserve System), on the third business day preceding the redemption date based upon the yield or yields for the most recent day that appear after such time on such day in the most recent statistical release published by the Board of Governors of the Federal Reserve System designated as “Selected Interest Rates (Daily) - H.15” (or any successor designation or publication) (“H.15”) under the caption “U.S. government securities-Treasury constant maturities-Nominal” (or any successor caption or heading) (“H.15 TCM”). In determining the Treasury Rate, the Company shall select, as applicable: (1) the yield for the Treasury constant maturity on H.15 exactly equal to the period from the redemption date to the applicable Par Call Date (the “Remaining Life”); or (2) if there is no such Treasury constant maturity on H.15 exactly equal to the Remaining Life, the two yields - one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the Treasury constant maturity on H.15 immediately longer than the Remaining Life - and shall interpolate to the applicable Par Call Date on a straight-line basis (using the actual number of days) using such yields and rounding the result to three decimal places; or (3) if there is no such Treasury constant maturity on H.15 shorter than or longer than the Remaining Life, the yield for the single Treasury constant maturity on H.15 closest to the Remaining Life. For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the redemption date.

of the preceding sentence, the Company shall select from among these two or more United States Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance with the terms of this paragraph, the semi-annual yield to maturity of the applicable United States Treasury security shall be based upon the average of the bid and asked prices (expressed as a percentage of principal amount) at 11:00 a.m., New York City time, of such United States Treasury security, and rounded to three decimal places.

“Winding-Up” will occur, with respect to any Person, if: (i) at any time an order is made, or an effective resolution is passed, for the winding-up of such Person (except, in any such case, a solvent winding-up solely for the purpose of a reorganization, merger or amalgamation or the substitution in place of such Person of a successor in business of such Person, the terms of which reorganization, merger, amalgamation or substitution (x) (A) have previously been approved in writing by the Trustee or by Holders of a majority in aggregate principal amount of the Outstanding Notes and (B) do not provide that the Notes or any amount in respect thereof shall thereby become payable) or (y) is permitted by the Indenture); or (ii) an administrator of such Person is appointed and such administrator gives notice that it intends to declare and distribute a dividend.

ARTICLE THREE

GENERAL TERMS AND CONDITIONS OF THE NOTES

SECTION 3.1. Title and Terms of Notes.

(a)The aggregate principal amount of the Notes which shall be authenticated and delivered on June 9, 2026 (the “Issue Date”) under the Indenture shall be $600,000,000 for the 2036 Notes and $1,400,000,000 for the 2056 Notes (and which shall initially be in the form of Global Notes); provided, however, that the Company from time to time, without giving notice to or seeking the consent of the Holders of the Notes, may issue additional senior notes in any amount having the same ranking and the same interest rate, interest payment dates, maturity and other terms as the Notes, except for the issue price, the issue date and, in some cases, the first interest payment date; any additional senior notes having such similar terms shall be authenticated by the Trustee upon receipt of a Company Order to that effect, and when so authenticated, will constitute “Notes” for all purposes of the Indenture and will (together with all other Notes of such series issued under the Indenture) constitute a single series of Securities under the Indenture. The Notes will be issued only in fully registered form without coupons in denominations of $2,000 and any whole multiple of $1,000 in excess of $2,000.

(b)The principal amount of the Notes of either series of Notes is due and payable in full on the Scheduled Maturity Date for such series of Notes, unless earlier redeemed, provided that the Conditions to Redemption for such series of Notes are met on such date, or, if the Conditions to Redemption of such series of Notes are not met on such date, on the Final Maturity Date for such series of Notes, subject to Section 4.1.

(c)The 2036 Notes shall bear interest at the rate of 5.250% per annum and the 2056 Notes shall bear interest at the rate of 5.950% per annum (each computed on the basis of a 360-day year comprised of twelve 30-day months) from the Issue Date or from the most recent Interest Payment Date to which interest has been paid or duly provided for to maturity or early redemption; and interest will be payable in each case, semi-annually on June 15 and December 15 of each year, commencing on December 15, 2026, to the Persons in whose name such Notes were registered at the close of business on the preceding June 1 or December 1, respectively.

(d)Principal of and interest on the Notes shall be payable in accordance with Sections 113, 307 and 1001 of the Original Indenture.

(e)Other than as provided in Article Four of this Third Supplemental Indenture, the Notes shall not be redeemable.

(f)The Notes shall not be entitled to the benefits of a sinking fund.

(g)The Notes shall not be convertible into any other securities.

(h)Section 404 of the Original Indenture shall apply to the Notes.

(i)The Company initially appoints the Trustee as Registrar and Paying Agent with respect to the Notes until such time as the Trustee has resigned or a successor has been appointed.

(j)The Company shall pay principal of, premium, if any, and interest on the Notes in money of the United States of America that at the time of payment is legal tender for payment of public and private debts.

(k)A Holder may transfer or exchange Notes only in accordance with the Indenture. Upon any transfer or exchange, the Registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements or transfer documents. No service charge shall be made for any registration of transfer or exchange, but the Company or the Trustee may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection therewith.

ARTICLE FOUR

OPTIONAL REDEMPTION; MATURITY

SECTION 4.1. Repayment at Final Maturity.

(a)Unless previously redeemed or purchased and cancelled, the Notes of either series of Notes will become finally due and payable, and will be repaid, on the Final Maturity Date for such series of Notes at a price equal to the principal amount thereof, together with accrued and unpaid interest on such series of Notes to, but excluding, the Final Maturity Date for such series of Notes.

For the avoidance of doubt, interest shall continue to accrue and be payable for so long as the principal amount of the Notes of such series remain Outstanding. In the event the Scheduled Maturity Date for such series of Notes and the Final Maturity Date for such series of Notes are not the same, the failure to repay such series of Notes on the Scheduled Maturity Date for such series of Notes will constitute neither an Event of Default under the Indenture nor a default of any kind and will not give Holders of such series of Notes or the Trustee any right to accelerate repayment of the Notes of such series or any other remedies (whether contractual, legal, equitable or otherwise).

(b)The Company will only be permitted to repay the principal amount of a series of Notes on the Scheduled Maturity Date for such series of Notes if the Conditions to Redemption for such series of Notes are satisfied on the Scheduled Maturity Date for such series of Notes.

(c)In the event that, with respect to a series of Notes:

(i)as of the Solvency Test Date for such series of Notes or any date thereafter and including on the Scheduled Maturity Date for such series of Notes or the Final Maturity Date for such series of Notes, as may be applicable, the Company (A) does not have sufficient capital to satisfy the Solvency Capital Requirement (the “First ECR Condition”) or (B) would not have sufficient capital to satisfy the Solvency Capital Requirement after giving effect to the repayment of the Notes of such series (the “Second ECR Condition” and, together with the First ECR Condition, each an “ECR Condition”), the Company will promptly begin using Commercially Reasonable Efforts, subject to the existence of a Market Disruption Event, to raise proceeds from the issuance of Qualifying Securities in an amount at least equal to the principal amount of the Notes of such series due to be repaid (the “Replacement Capital Obligation”);

(ii)on or after the Solvency Test Date for such series of Notes and prior to the Scheduled Maturity Date for such series of Notes, the Company is unable to satisfy any ECR Condition, the Company will, within 10 Business Days of the principal executive officer or the principal financial officer of the Company becoming aware of the Company’s inability to so satisfy such ECR Condition, notify the Trustee in writing of such inability (which the Trustee will promptly disseminate to the Holders of the Notes); provided, however, that the Company will provide any such notice no later than the Business Day immediately preceding the Scheduled Maturity Date for such series of Notes; and

(iii)the Scheduled Maturity Date for such series of Notes and Final Maturity Date for such series of Notes are not the same, after a Final Maturity Date for such series of Notes has been established:

then:

(A)the Company will promptly notify the Trustee in writing of such Final Maturity Date for such series of Notes (which the Trustee will promptly disseminate to the Holders of the Notes); and

(B)if the Company is then unable to satisfy any ECR Condition as of such Final Maturity Date for such series of Notes, the Company will, promptly after the principal executive officer or the principal financial officer of the Company becomes aware of the Company’s inability to so satisfy such ECR Condition, notify the Trustee in writing of such inability (which the Trustee will promptly disseminate to the Holders of the Notes for such series of Notes); provided, however, that the Company will provide any such notice no later than the Business Day immediately preceding such Final Maturity Date for such series of Notes.

If a successful issuance of Qualifying Securities satisfying the Replacement Capital Obligation occurs after the Solvency Test Date for such series of Notes, but prior to the Scheduled Maturity Date for such series of Notes or the Final Maturity Date for such series of Notes, as may be applicable (an “RCO Satisfying Issuance”), then (i) such RCO Satisfying Issuance will constitute an issuance of replacement capital in satisfaction of the Conditions to Redemption for a series of Notes for redemptions or repayments occurring prior to or on the Scheduled Maturity

Date for such series of Notes or the Final Maturity Date for such series of Notes, as may be applicable, and (ii) the Company will promptly notify the Trustee of such RCO Satisfying Issuance in writing (which the Trustee will promptly disseminate to the Holders of the Notes for such series of Notes). Subject to the prior sentence, the Replacement Capital Obligation will continue to apply until the earliest of (a) an RCO Satisfying Issuance, (b) the Conditions to Redemption for such series of Notes are satisfied by means other than an RCO Satisfying Issuance; provided that, if the Conditions to Redemption for such series of Notes cease to be satisfied prior to the Final Maturity Date for such series of Notes, the Replacement Capital Obligation will be reinstated or (c) an Event of Default occurs. Accordingly, the Replacement Capital Obligation will cease to apply if the Company is able to restore its compliance with the Solvency Capital Requirement, after giving effect to repayment of such series of Notes, by a means other than the issuance of Qualifying Securities or with an issuance of Qualifying Securities that is less than the principal amount of the Notes of such series, subject to the reinstatement of the Replacement Capital Obligation as described in the preceding sentence.

The Company’s failure to use Commercially Reasonable Efforts to raise sufficient proceeds from the issuance of Qualifying Securities to satisfy the Replacement Capital Obligation, where required hereunder and subject to the existence of a Market Disruption Event, will potentially constitute a breach hereunder (a “Replacement Capital Obligation Default”), but it will not in any case constitute a default or an Event of Default hereunder or give rise to a right of acceleration of payment of the Notes or any other remedy under the terms hereunder or the Notes. The sole remedy for a Replacement Capital Obligation Default is for the Trustee or the Holders of at least 25% in aggregate principal amount of the Notes (provided that no Holder of the Notes may pursue any such remedy hereunder unless the Trustee will have failed to act after, among other things, notice of a breach of such covenant and request by Holders of at least 25% in principal amount of the Notes has occurred and the offer to the Trustee of indemnity satisfactory to it) to bring suit for specific performance of the Company’s obligations with respect to such covenant to use such Commercially Reasonable Efforts with respect to the Replacement Capital Obligation.

For the avoidance of doubt, the Replacement Capital Obligation will not apply at any time while the Solvency Capital Requirement is satisfied, and if the Company continues to satisfy the Solvency Capital Requirement after giving effect to a redemption or repayment of the Notes on the Scheduled Maturity Date for such series of Notes or the Final Maturity Date for such series of Notes, as may be applicable.

(d)If the Company is subject to a Replacement Capital Obligation, it may provide written certification to the Trustee (which the Trustee will promptly disseminate to the Holders of the Notes) within ten (10) Business Days of the later of (i) the occurrence of a Market Disruption Event and (ii) the beginning of the period of the Replacement Capital Obligation (if such Market Disruption Event occurred prior to the Replacement Capital Obligation period beginning and is continuing) certifying that a Market Disruption Event has occurred and is continuing, if such notice is provided the Company will be excused from its obligation to use Commercially Reasonable Efforts to issue Qualifying Securities pursuant to the Replacement Capital Obligation for an initial suspension period of 90 consecutive days following such

certification. The Company may extend a suspension period by providing written certification to the Trustee (which the Trustee will promptly disseminate to the Holders of the Notes) on or prior to the expiration of such suspension period, certifying that the applicable Market Disruption Event is continuing, in which case, the Company’s obligation to use Commercially Reasonable Efforts to issue Qualifying Securities pursuant to the Replacement Capital Obligation will be excused for an additional 60 consecutive days following such further certification. Following the expiration of the applicable suspension period, the Company’s obligation to use Commercially Reasonable Efforts to issue Qualifying Securities pursuant to the Replacement Capital Obligation will be reinstated. The Company’s ability to initiate or extend a suspension period in connection with a Market Disruption Event will also be subject to the limits on suspension periods provided for in the definition of Market Disruption Event (if applicable). Notwithstanding the foregoing time limitations as to suspension in connection with a particular Market Disruption Event, the suspension of the Company’s obligations pursuant to the foregoing will not prohibit the further suspension of obligations in connection with, and the Company will be entitled to provide separate notices with respect to, any separate and distinct Market Disruption Event(s). In addition, for the avoidance of doubt, the Company will not be prohibited during any suspension of the requirements to use Commercially Reasonable Efforts during a Market Disruption Event from issuing any Qualifying Securities.

For the avoidance of doubt, the Trustee shall have no responsibility to make any determinations or calculations with respect to (i) the Replacement Capital Obligation or any terms thereof, which collectively will be the responsibility of the Company, (ii) the occurrence or continuation of any Market Disruption Event, which will be determined by the Company, or (iii) the occurrence or continuation of any Replacement Capital Obligation Default, which will be made by the Holders of the Notes.

SECTION 4.2. Optional Redemption.

(a)Subject to the Conditions to Redemption for a series of Notes, the Notes of such series will be redeemable, in whole at any time or in part from time to time before the applicable Par Call Date, at the Company’s option, at a Redemption Price equal to accrued and unpaid interest on the principal amount being redeemed to, but not including, the Redemption Date plus the greater of: (1) (A) the sum of the present values of the remaining scheduled payments of principal and interest on the Notes to be redeemed thereon discounted to the date of redemption (assuming, in the case of the 2036 Notes, the 2036 Notes matured on the 2036 Par Call Date, and in the case of the 2056 Notes, the 2056 Notes matured on the 2056 Notes Par Call Date) on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate, plus (i) in the case of the 2036 Notes, 15 basis points, and (ii) in the case of the 2056 Notes, 15 basis points, in each case, less (B) interest accrued to the date of the redemption and (2) 100% of the principal amount of the Notes of such series to be redeemed, plus, in either case, accrued and unpaid interest thereon to, but excluding, the Redemption Date. Subject to the Conditions to Redemption for a series of Notes, the Notes of such series will be redeemable, in whole at any time or in part from time to time on or after the applicable Par Call Date, at the Company’s option, at a Redemption Price equal to accrued and unpaid interest on the principal amount being redeemed to, but not including, the Redemption Date plus 100% of the

principal amount of the Notes of such series to be redeemed. Interest on the Notes of such series for which the Redemption Date is after a Regular Record Date and before the following Interest Payment Date, shall be payable to the holder of such series of Notes at the close of business on the Regular Record Date. Unless the Company defaults in payment of the Redemption Price, on and after the Redemption Date, interest will cease to accrue on the Notes of such series or portions of the Notes of a series called for redemption.

Notwithstanding the foregoing, the Company may, at its sole option, subject to the Conditions to Redemption for a series of Notes, redeem such series of Notes, at any time, in whole but not in part, following the occurrence of a Tax Event, at a Redemption Price equal to 100% of the principal amount of such series of Notes, plus accrued and unpaid interest on such series of Notes to, but excluding, the Redemption Date, subject to the right of a holder on the relevant Regular Record Date to receive accrued and unpaid interest on such series of Notes due on the relevant Interest Payment Date.

The Company’s actions and determinations in determining the Redemption Price shall be conclusive and binding for all purposes, absent manifest error. For the avoidance of doubt, the Trustee shall have no responsibility to determine (or to verify or review the Company’s determination of) the Redemption Price or the Treasury Rate.

SECTION 4.3. Redemption Procedures.

(a)The provisions of Article Eleven of the Original Indenture shall apply in the case of a redemption pursuant to a notice of redemption pursuant to Section 4.2; provided, that notice of redemption shall be given by first-class mail, postage prepaid, mailed, electronically delivered (or, in the case of Global Notes, delivered in accordance with the Depositary’s applicable procedures) not less than 10 nor more than 60 days prior to the Redemption Date, to each Holder of Notes to be redeemed, at his address appearing in the Security Register. Any redemption of Global Notes shall be done in accordance with the procedures of the Depositary. In the event that fewer than all the Notes of a particular series will be redeemed, the Notes of such series will be selected for redemption, if the Notes of such series are Global Notes, in accordance with the applicable procedures of the depository or, if the Notes of such series are in certificated form, by lot.

(b)Notices of redemption may, in the Company’s sole discretion, be subject to one or more conditions precedent, including, but not limited to, the consummation of a financing transaction, equity offering, asset disposition or other corporate transaction (or a series of such transactions) or the satisfaction of the Conditions to Redemption for a series of Notes. In addition, if such redemption is subject to satisfaction of any such condition, the notice of redemption may state that, in the Company’s discretion, the Redemption Date may be delayed until such time as such condition shall be satisfied, or such redemption may not occur and such notice may be rescinded in the event that such condition shall not have been satisfied by the Redemption Date, or the Redemption Date so delayed.

ARTICLE FIVE

COVENANTS

SECTION 5.1. Covenants.

(a)Each series of Notes shall be entitled to the benefit of each of the covenants in Article Ten of the Original Indenture and the following additional covenants (which shall be deemed to be provisions of the Original Indenture and made subject to the provisions of Section 1006 of the Original Indenture and, when referred to as a provision of the Original Indenture, shall be identified by reference to the Section number that is set forth immediately preceding the covenant):

SECTION 1007. Limitation on Liens on Stock of Designated Subsidiaries.

The Company shall not, and shall not permit any Designated Subsidiary to, create, assume, incur or guarantee any indebtedness for borrowed money if that indebtedness is evidenced by notes, debentures, bonds or similar negotiable instruments, which is secured by any mortgage, pledge, lien, security interest or other encumbrance (each, a “Lien”) upon any shares of Capital Stock of any Designated Subsidiary owned by the Company or such Designated Subsidiary (whether such shares of stock are now owned or hereafter acquired) without effectively providing concurrently that the Notes (and, if the Company so elects, any other indebtedness of the Company that is not subordinated to the Notes and with respect to which the governing instruments require, or pursuant to which we are otherwise obligated, to provide such security) will be secured equally and ratably with such indebtedness for at least the time period such other indebtedness is so secured. This restriction will not apply to indebtedness secured by (i) Liens on any shares of stock or indebtedness of or acquired from a Person that is merged or consolidated with or into, or is otherwise acquired by, the Company or any Designated Subsidiary, (ii) Liens to secure indebtedness of a Designated Subsidiary to the Company or another Designated Subsidiary (but only for so long as such indebtedness is owned or held by the Company or another Designated Subsidiary), (iii) Liens existing at the time a Subsidiary becomes a Designated Subsidiary; and (iv) any extension, renewal or replacement (or successive extensions, renewals or replacements), in whole or in part, of any Lien referred to in clauses (i) through (iii) above.

SECTION 1008. Limitation on the Disposition of Stock of Designated Subsidiaries.

So long as any Notes are Outstanding, the Company will not, nor will the Company permit any Designated Subsidiary to issue, sell, assign, transfer or otherwise dispose of any shares of Capital Stock of any Designated Subsidiary; provided, however, that the foregoing shall not apply to any issuance, sale, assignment, transfer or disposition of Capital Stock (i) required by any law, regulation or order of any court, or governmental or insurance regulatory authority, unless any such order was requested by the Company or any of the Designated Subsidiaries, (ii) for fair market value, as determined in good faith by the Company’s Board of Directors or (iii) to the Company or any of its Subsidiaries.”

(b)For purposes only of the Notes and Sections 1007 and 1008 of the Indenture, the following terms shall have the following meanings:

“Capital Stock” of any Person means any and all shares, interests, rights to purchase, warrants, options, participations or other equivalents of or interests in (however designated) equity of such person, including preferred stock, in each case, which are entitled to vote in the election of directors, member or general partners or other similar managing body, as applicable, but excluding any debt securities convertible into or other securities convertible into such equity; provided, however, that preferred shares or other similar securities issued in the ordinary course of business by any of the Company’s Subsidiaries in connection with their “rent-a-captive” business shall not be deemed capital stock for purposes of the covenants described herein.

“Designated Subsidiary” means any present or future consolidated Subsidiary of the Company, (a) the assets of which constitute at least 20% of the Company’s consolidated assets and (b) in which the Company holds, directly or indirectly, equity interests entitled to more than 50% of the profits thereof; provided, however, that (i) in the event Liens of the type described in Section 1007 are placed on the Capital Stock of more than one of the Company’s Subsidiaries in one transaction or in a series of related transactions and such Subsidiaries, when taken together as a whole, constitute at least 20% of the Company’s consolidated assets, each such Subsidiary shall be deemed to be a “Designated Subsidiary” for purposes of such transaction or transactions, as the case may be, and (ii) in the event of a sale, transfer or other disposition of the type described in Section 1008 of any shares of Capital Stock of more than one of the Company’s Subsidiaries in one transaction or in a series of related transactions and such Subsidiaries, when taken together as a whole, constitute at least 20% of the Company’s consolidated assets, each such Subsidiary shall be deemed to be a “Designated Subsidiary” for purposes of such transaction or transactions, as the case may be.

“Lien” shall have the meaning set forth in Section 1007 hereof.

(c)For purposes of the Indenture and the Notes, the first paragraph of Section 1003 of the Original Indenture is hereby amended in its entirety and replaced with the following:

If the Company shall at any time act as its own Paying Agent with respect to any series of Securities, it will, immediately prior to such due date of the principal of (and premium, if any) or interest on any of the Securities of that series, segregate and hold in trust for the benefit of the Persons entitled thereto a sum (in the currency in which the Securities of such series are payable) sufficient to pay the principal (and premium, if any) or interest so becoming due until such sums shall be paid to such Persons or otherwise disposed of as herein provided and will promptly notify the Trustee of its action or failure so to act.

(d)For purposes of the Indenture and the Notes, Section 1004 of the Original Indenture is hereby amended in its entirety and replaced with the following:

“SECTION 1004. Corporate Existence.

Except as otherwise permitted under Article Eight and Section 1008, the Company will do or cause to be done all things necessary to preserve and keep in full force and effect its corporate existence and material rights (charter and statutory) and franchises; provided, however, that the Company will not be required to preserve any such right or franchise if the Board of Directors or senior management of the Company determines that the preservation thereof is no longer desirable in the conduct of the business of the Company and that the loss thereof is not disadvantageous in any material respect to the Holders.”

SECTION 5.2. Payment of Additional Amounts

(a)The Company will make all payments under the Notes without withholding or deduction at source for, or on account of, any present or future taxes, duties, assessments or similar governmental charges (“Taxes”) unless such Taxes are required to be withheld or deducted by (i) the laws (or any regulations or rulings promulgated thereunder) of any taxing jurisdiction or (ii) any official position regarding the application, administration, interpretation or enforcement of any such laws, regulations or rulings (including, without limitation, a holding by a court of competent jurisdiction or by a taxing authority in a taxing jurisdiction). If any such withholding or deduction at source is required with respect to any Tax imposed or levied by any Relevant Taxing Jurisdiction, the Company will, subject to certain limitations and exceptions described below, pay to each holder of any Notes such additional amounts as may be necessary, if any, so that every net payment of principal, premium, if any, interest or any other amount made to such holder under the Notes, after such withholding or deduction, will equal the amount provided for in the Indenture to be then due and payable (any such additional amounts, “Additional Amounts”).

(b)Notwithstanding the foregoing, the Company will not be required to pay any Additional Amounts for or on account of:

(i)any Tax which would not have been imposed but for the fact that the applicable holder or beneficial owner of a Note (1) is or was a resident, domiciliary or national of, engages or engaged in business in, maintains or maintained a permanent establishment in, or is or was physically present in, the Relevant Taxing Jurisdiction or had some other present or former connection with the Relevant Taxing Jurisdiction other than by reason of the mere ownership of, or receipt of payment under, such Note, (2) presented such Note for payment in the Relevant Taxing Jurisdiction, unless such Note could not have been presented for payment elsewhere, or (3) presented such Note for payment more than 30 days after the date on which the payment in respect of such Note became due and payable or provided for, whichever is later, except to the extent that the holder would have been entitled to such Additional Amounts if it had presented such Note for payment on any day within that 30-day period;

(ii)any estate, inheritance, gift, net worth, wealth, sale, use, gains, excise, value added transfer, personal property or similar Tax;

(iii)any Tax that is imposed or withheld by reason of the failure by the holder or beneficial owner of such Note to comply with any reasonable request by the Company addressed to the holder or beneficial owner within 90 days of such request (1) to provide

information concerning the nationality, residence or identity of such holder or such beneficial owner or (2) to make any declaration or other similar claim or satisfy any information or reporting requirement, which is required or imposed by statute, treaty, regulation or administrative practice of the Relevant Taxing Jurisdiction as a precondition to an exemption from, or reduction in, such Tax;

(iv)any Tax that is imposed other than by means of withholding in respect of payments made under a Note;

(v)any Taxes imposed on or measured by overall net income (however denominated) or any branch profits tax;

(vi)any withholding or deduction imposed pursuant to current Sections 1471 through 1474 of the Internal Revenue Code of 1986, as amended (or any amended or successor version thereof), any current or future regulations promulgated thereunder or official interpretations thereof, any intergovernmental agreements, treaties or conventions in connection therewith (or any laws, regulations or official administrative guidance implementing such agreements, treaties or conventions), and any agreements entered into pursuant to Section 1471(b)(1) of the Internal Revenue Code of 1986, as amended (or any amended or successor version thereof); or

(vii)any combination of items (i), (ii), (iii), (iv), (v) and (vi) above.

In addition, the Company will not pay Additional Amounts with respect to any holder who is a fiduciary or partnership or otherwise not the sole beneficial owner of such Note to the extent that a beneficiary, partner or settlor with respect to such fiduciary or a member of such partnership or a beneficial owner would not have been entitled to such Additional Amounts had it been the holder of such Note.

In order to comply with applicable tax laws (inclusive of rules, regulations and interpretations promulgated by competent authorities) related to the Indenture in effect from time to time (“Applicable Law”) that a foreign financial institution, issuer, trustee, paying agent or other party is or has agreed to be subject to, the Company agrees to provide to the Trustee and the Paying Agent information about the parties and/or transactions (including any modification to the terms of such transactions) reasonably requested by the Trustee to allow the Trustee or the Paying Agent to determine whether it has Tax-related obligations under Applicable Law.

The obligations described in this Section 5.2 will survive any termination, defeasance or discharge of the Indenture.

Prior to the date on which the payment of any Additional Amounts are due, the Company will deliver to the Trustee an Officer’s Certificate stating that such Additional Amounts will be payable on the applicable Payment Date and setting forth the amounts so payable and any other information necessary to enable the Trustee (or applicable Paying Agent) to pay such Additional Amounts to holders on the Payment Date. Any such Officer’s Certificate will be delivered at least two Business Days in advance of when the payments in question are

required to be made (unless a shorter period of time is acceptable to the Trustee in its reasonable discretion).

SECTION 7.6. Conflict.

In the event that there is a conflict or inconsistency between the Original Indenture and this Third Supplemental Indenture, the provisions of this Third Supplemental Indenture shall control; provided, however, if any provision hereof limits, qualifies or conflicts with another provision herein or in the Original Indenture, in either case, which is required or deemed to be included in this Indenture by any of the provisions of the Trust Indenture Act, such required or deemed provision shall control.

SECTION 7.7. Governing Law.

THIS THIRD SUPPLEMENTAL INDENTURE AND THE NOTES SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

The Trustee shall not be responsible in any manner whatsoever for or in respect of the validity or sufficiency of this Third Supplemental Indenture or for or in respect of the recitals contained herein, all of which are made solely by the Company.

This instrument may be executed in any number of counterparts, each of which so executed shall be deemed to be an original, but all such counterparts shall together constitute but one and the same instrument. Signatures to this Third Supplemental Indenture transmitted by electronic mail (including any electronic signature complying with the U.S. federal ESIGN Act

of 2000, Uniform Electronic Transactions Act or other applicable law, e.g., www. Docusign.com) in “portable document format” (“.pdf”) form, or by any other electronic means intended to preserve the original graphic and pictorial appearance of a document, will have the same effect as physical delivery of the paper document bearing the original signature.

In no event shall the Trustee be responsible or liable for special, indirect, punitive or consequential loss or damage of any kind whatsoever (including, but not limited to, loss of profit) irrespective of whether the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action.

The Trustee shall not be deemed to have notice of any default or Event of Default (other than with respect to an Event of Default arising out of the failure to pay interest or principal on the Notes) unless written notice of any event which is in fact such a default is received by a Responsible Officer of the Trustee at the Corporate Trust Office of the Trustee, and such notice references the Securities and this Indenture.

SECTION 7.9. Amendments.

(a)The following new paragraphs are hereby added to Section 105 of the Indenture:

The Trustee shall have the right to accept and act upon instructions, including funds transfer instructions (“Instructions”) given pursuant to this Indenture and delivered using Electronic Means; provided, however, that the Company shall provide to the Trustee an incumbency certificate listing officers with the authority to provide such Instructions (“Authorized Officers”) and containing specimen signatures of such Authorized Officers, which incumbency certificate shall be amended by the Company whenever a person is to be added or deleted from the listing. If the Company elects to give the Trustee Instructions using Electronic Means and the Trustee in its discretion elects to act upon such Instructions, the Trustee’s understanding of such Instructions shall be deemed controlling. The Company understands and agrees that the Trustee cannot determine the identity of the actual sender of such Instructions and that the Trustee shall conclusively presume that directions that purport to have been sent by an Authorized Officer listed on the incumbency certificate provided to the Trustee have been sent by such Authorized Officer. The Company shall be responsible for ensuring that only Authorized Officers transmit such Instructions to the Trustee and that the Company and all Authorized Officers are solely responsible to safeguard the use and confidentiality of applicable user and authorization codes, passwords and/or authentication keys upon receipt by the Company. The Trustee shall not be liable for any losses, costs or expenses arising directly or indirectly from the Trustee’s reliance upon and compliance with such Instructions notwithstanding such directions conflict or are inconsistent with a subsequent written instruction. The Company agrees: (i) to assume all risks arising out of the use of Electronic Means to submit Instructions to the Trustee, including without limitation the risk of the Trustee acting on unauthorized Instructions, and the risk of interception and misuse by third parties; (ii) that it is fully informed of the protections and risks associated with the various methods of transmitting Instructions to the Trustee and that there may be more secure methods of transmitting Instructions than the method(s) selected by the Company; (iii) that the security procedures (if

any) to be followed in connection with its transmission of Instructions provide to it a commercially reasonable degree of protection in light of its particular needs and circumstances; and (iv) to notify the Trustee immediately upon learning of any compromise or unauthorized use of the security procedures.

Notwithstanding any other provision of this Indenture or any Security, where this Indenture or any Security provides for notice of any event or any other communication (including any notice of redemption or repurchase) to a Holder of a Global Security (whether by mail or otherwise), such notice shall be sufficiently given if given to the Depositary (or its designee) pursuant to the standing instructions from the Depositary or its designee, including by electronic mail in accordance with accepted practices at the Depositary.

(b)The first sentence of Section 202 of the Indenture is hereby deleted in its entirety and replaced with following:

The Trustee’s certificate of authentication required by this article shall be in substantially the form set forth below and executed by the Trustee by manual or electronic signature.

(c)The last sentence of Section 303 of the Indenture is hereby deleted in its entirety and replaced with following:

No Security shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose unless there appears on such Security a certificate of authentication substantially in the form provided for herein executed by the Trustee by manual or electronic signature, and such certificate upon any Security shall be conclusive evidence, and the only evidence, that such Security has been duly authenticated and delivered hereunder and is entitled to the benefits of this Indenture.

(d)The first sentence of Section 901 of the Indenture is hereby deleted in its entirety and replaced with the following:

The Company and the Trustee, at any time and from time to time, may amend or supplement this Indenture or the Securities without the consent of any Holder, so long as such changes (other than those in clauses (1), (2) or (7)) do not materially and adversely affect the interests of the Holder:

(e)The first sentence of Section 902 of the Indenture is hereby deleted in its entirety and replaced with the following:

With the written consent of the Holders of not less than a majority in aggregate principal amount of the Securities of such series affected by such amendment or supplement at the time Outstanding, the Company and the Trustee, at any time and from time to time, may amend or supplement this Indenture or such series of Securities.

SECTION 7.10. Force Majeure.

In no event shall the Trustee be responsible or liable for any failure or delay in the performance of its obligations hereunder arising out of or caused by, directly or indirectly, forces beyond its control, including, without limitation, strikes, work stoppages, accidents, acts of war or terrorism, civil or military disturbances, epidemics or pandemics, nuclear or natural catastrophes or acts of God, and interruptions, loss or malfunctions of utilities, communications or computer (software and hardware) services; it being understood that the Trustee shall use reasonable efforts which are consistent with accepted practices in the banking industry to resume performance as soon as practicable under the circumstances.

SECTION 7.11. Waiver of Jury Trial.

EACH OF THE COMPANY, THE HOLDERS BY THEIR ACCEPTANCE OF THE NOTES, AND THE TRUSTEE HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS THIRD SUPPLEMENTAL INDENTURE, THE ORIGINAL INDENTURE, THE NOTES OR THE TRANSACTION CONTEMPLATED HEREBY.

5.250% Senior Note due 2036

1.Interest

Arch Capital Group Ltd., a Bermuda company limited by shares (such company, and its successors and assigns under the Indenture hereinafter referred to, being herein called the “Company”), for value received, promises to pay interest on the principal amount of this Note (the “Note”) at the rate of 5.250% per annum. The Company shall pay interest semiannually, in arrears, on June 15th and December 15th of each year, commencing December 15, 2026. Interest on the Note shall accrue from the most recent date to which interest has been paid or duly provided for or, if no interest has been paid or duly provided for, from June 9, 2026 until the principal hereof is due. Interest shall be computed on the basis of a 360-day year comprised of twelve 30-day months. The Company shall pay interest on overdue principal at the rate borne by the Note, and it shall pay interest on overdue installments of interest at the same rate to the extent lawful.

2.Method of Payment

The Company shall pay interest on the Note (except defaulted interest, which shall be paid pursuant to Section 307 of the Original Indenture) to the Persons who are registered Holders at the close of business on the June 1 or December 1 next preceding the Interest Payment Date even if Notes are canceled after the record date and on or before the Interest Payment Date. The Company shall pay principal, premium, if any, and interest in money of the United States of America that at the time of payment is legal tender for payment of public and private debts. Payment of principal (and premium, if any) and interest in respect of Notes represented by a Global Security will be made by wire transfer of immediately available funds to the accounts specified by the Depository. Payments of principal (and premium, if any) and interest in respect of a certificated Note may be made, at the option of the Company, either by wire transfer in immediately available funds to the accounts specified by registered Holders as of the relevant record dates or (subject to collection) by check mailed to the address of the registered Holders as of the relevant record dates or at the specified offices of any Paying Agent. Payment of principal in respect of a certificated Note will only be made against presentation and, provided that payment is made in full, surrender of the appropriate certificate at the specified offices of any Paying Agent.

3.Repayment at Final Maturity

(a) Unless previously redeemed or purchased and cancelled, the Notes will become finally due and payable, and will be repaid, on the Final Maturity Date at a price equal to the principal amount thereof, together with accrued and unpaid interest on the Notes to, but excluding, the Final Maturity Date.

For the avoidance of doubt, interest shall continue to accrue and be payable for so long as the principal amount of the Notes remain Outstanding. In the event the Scheduled Maturity Date and the Final Maturity Date are not the same, the failure to repay the Notes on the

Exhibit I - 4

Scheduled Maturity Date will constitute neither an Event of Default under the Indenture nor a default of any kind and will not give Holders of the Notes or the Trustee any right to accelerate repayment of the Notes or any other remedies (whether contractual, legal, equitable or otherwise).

(b) The Company will only be permitted to repay the principal amount of the Notes on the Scheduled Maturity Date if the Conditions to Redemption are satisfied on the Scheduled Maturity Date.

“Final Maturity Date” means with respect to the Notes, a date after the Scheduled Maturity Date that is the earlier of (i) 10 Business Days after the applicable Conditions to Redemption become satisfied and would continue to be satisfied if the final redemption payment were made on such date (so long as such requirements continue to be so satisfied on such 10th Business Day), and (ii) the date on which a Winding-Up occurs with respect to the Company.

4.Paying Agent and Registrar

Initially, THE BANK OF NEW YORK MELLON, a New York banking corporation (the “Trustee”), will act as Paying Agent and Registrar with respect to the Notes. The Company may appoint and change any Paying Agent or Registrar without notice. The Company may act as Paying Agent or Registrar.

5.Indenture

The Company issued the Notes under an Indenture dated as of May 4, 2004, by and between the Company and the Trustee (the “Original Indenture”), as supplemented by a Third Supplemental Indenture dated June 9, 2026, by and between the Company and the Trustee (the “Third Supplemental Indenture”), which collectively constitutes the indenture governing the Securities (the “Indenture”). The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended as in effect on the date of the Indenture (the “TIA”). The Notes include all terms and provisions of the Indenture, and Holders are referred to the Indenture and the TIA for a statement of such terms and provisions. This Security is one of a series of Securities designated as the 5.250% Senior Notes due 2036 of the Company (the “Notes”). Capitalized terms used herein have the same meanings given in the Indenture unless otherwise indicated.

The aggregate principal amount at maturity of the Notes which may be authenticated and delivered under the Indenture shall be unlimited. In addition, the aggregate principal amount of Securities of any class or series which may be authenticated and delivered under the Indenture shall be unlimited, provided that such Securities shall rank equally with the Notes.

The Indenture imposes certain limitations on the ability of each of the Company and the Designated Subsidiaries to, among other things, create or incur Liens and to sell or

Exhibit I - 5

otherwise dispose of Designated Subsidiaries. The Indenture also imposes limitations on the ability of the Company to consolidate or amalgamate with or merge into any other Person or convey, transfer, sell or lease its property or assets substantially as an entirety to any Person.

Subject to the Conditions to Redemption, the Notes will be redeemable, in whole at any time or in part from time to time on or after the Par Call Date, at the Company’s option, at a Redemption Price equal to accrued and unpaid interest on the principal amount being redeemed to, but not including, the Redemption Date plus 100% of the principal amount of the Notes to be redeemed Interest on the Notes for which the Redemption Date is after a Regular Record Date and before the following Interest Payment Date, shall be payable to the Holder of such Notes at the close of business on the Regular Record Date. Unless the Company defaults in payment of the Redemption Price, on and after the Redemption Date, interest will cease to accrue on the Notes or portions of the Notes called for redemption.

Notwithstanding the foregoing, the Company may, at its sole option, subject to the Conditions to Redemption, redeem the Notes, at any time, in whole but not in part, following the occurrence of a Tax Event at a Redemption Price equal to 100% of the principal amount of the Notes, plus accrued and unpaid interest on the Notes to, but excluding, the Redemption Date, subject to the right of a Holder on the relevant Regular Record Date to receive accrued and unpaid interest on the Notes due on the relevant Interest Payment Date.

As used in this Section 7, the following terms shall have the respective meanings set forth below:

Exhibit I - 6

“Conditions to Redemption” are satisfied in relation to any redemption on any day, including with respect to a scheduled redemption of or planned purchase of the Notes, if:

(i)the Solvency Capital Requirement is complied with immediately before and after the repayment or purchase of the Notes unless the capital represented by the Notes to be redeemed or repaid is replaced without delay with the issuance of capital having equal or better treatment as the Notes under the Group Rules, approved by the BMA; and

(ii) with regard to redemptions occurring prior to June 9, 2029, the BMA has given, and not withdrawn by such date, its prior consent to the redemption of the Notes and the payment of accrued and unpaid interest or to the purchase of the Notes; provided, that if under the Applicable Supervisory Regulations no such consent is required at the time in order for Notes to qualify or continue to qualify, as applicable, as Tier 3 Capital of the Company or the Insurance Group, this clause (ii) shall not apply.

If there are two or more United States Treasury securities maturing on the applicable Par Call Date or two or more United States Treasury securities meeting the criteria of the preceding sentence, the Company shall select from among these two or more United States Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance with the terms of this paragraph, the semi-annual yield to maturity of the applicable United States Treasury security shall be based upon the average of the bid and asked prices (expressed as a percentage of principal amount) at 11:00 a.m., New York City time, of such United States Treasury security, and rounded to three decimal places. The Company’s actions and determination in determining the Redemption Price shall be conclusive and binding for all purposes, absent manifest error.
