RECITALS

WHEREAS, the Company and the Trustee are parties to that certain Indenture dated as of August 23, 2001 (the “Indenture,” all capitalized terms used and not otherwise defined herein shall have the meanings set forth in the Indenture) providing for the issuance by the Company of securities from time to time;

WHEREAS, the Company desires to issue a new series of Securities under the Indenture, and has duly authorized the creation and issuance of such Securities and the execution and delivery of this Fourth Supplemental Indenture to modify the Indenture and provide certain additional provisions as hereinafter described;

WHEREAS, the Company and the Trustee deem it advisable to enter into this Fourth Supplemental Indenture for the purposes of establishing the terms of such series of Securities;

WHEREAS, the execution and delivery of this Fourth Supplemental Indenture has been authorized by a Board Resolution;

WHEREAS, concurrent with the execution hereof, the Company has delivered an Officers’ Certificate and has caused its counsel to deliver to the Trustee an Opinion of Counsel; and

WHEREAS, all things necessary to make this Fourth Supplemental Indenture a valid agreement of the Company in accordance with its terms have been done, and the execution and delivery thereof have been in all respects duly authorized by the parties hereto.

NOW, THEREFORE, for and in consideration of the premises and the purchase of the Securities by the Holders thereof, it is mutually agreed, for the equal and proportionate benefit of all Holders of the Notes (as hereinafter defined), as follows:

ARTICLE 1

Creation Of The Notes

Section 1.01 Designation of Series. Pursuant to the terms hereof and Section 301 of the Indenture, the Company hereby creates a series of Securities designated as the “6.300% Senior Notes due 2019” (the “Notes”), which Notes shall be deemed “Securities” for all purposes under the Indenture.

Section 1.02 Form of Note; Denomination. The Notes shall be substantially in the form set forth in Exhibit A attached hereto, which is incorporated herein and made part hereof. The Stated Maturity of the principal amount of the Notes shall be November 15, 2019. The Company will issue the Notes in denominations of $2,000 and integral multiples of $1,000 in excess thereof.

Section 1.03 Limit on Amount of Series. The Notes shall not exceed U.S. $300,000,000 in aggregate principal amount, and may, upon the execution and delivery of this Fourth Supplemental Indenture or from time to time thereafter, be executed by the Company and delivered to the Trustee for authentication, and the Trustee shall thereupon authenticate and deliver said Notes upon a Company Order and delivery of an Officers’ Certificate and Opinion of Counsel as contemplated by Section 303 of the Indenture.

Section 1.04 Interest. The Company shall pay interest on the aggregate principal amount of the Notes at 6.300% per annum until the principal amount of the Notes is paid or made available for payment. The

Company shall pay interest, semi-annually in arrears on May 15 and November 15, of each year, or if any such day is not a Business Day, on the next succeeding Business Day, commencing on May 15, 2010 (each an “Interest Payment Date”) and such interest shall be paid to the Person in whose name the Note is registered at the close of business on the Regular Record Date (whether or not a Business Day) immediately preceding the Interest Payment Date. Interest on the Notes will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from November 16, 2009. The Company shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest (without regard to any applicable grace periods) from time to time on demand at the same rate to the extent lawful. Interest will be computed on the basis of a 360-day year of twelve 30-day months.

Interest, including interest payable at Stated Maturity, shall be payable at the office of the Company maintained by the Company for such purposes in the Borough of Manhattan, The City of New York, which shall initially be an office or agency of the Trustee, and may, as the Company shall specify to the Paying Agent in writing by each Regular Record Date, be paid either (i) by check mailed or delivered to the Holders of the Notes at their respective addresses set forth in the Security Register or (ii) by wire transfer of immediately available funds to an account previously specified in writing by the Holder to the Company and the Trustee; provided, however, that payments to the Depositary will be made by wire transfer of immediately available funds to the account of the Depositary or its nominee.

Maturity or redemption of a Note will cause interest to cease to accrue on such Note. The Company can not reissue a Note that has matured, redeemed or otherwise cancelled, except for registration of transfer, exchange or replacement of such Note.

Section 1.05 Certificate of Authentication. The Trustee’s certificate of authentication to be borne on the Notes shall be substantially as provided in the Form of Note attached hereto as Exhibit A.

Section 1.06 No Sinking Fund. No sinking fund will be provided with respect to the Notes.

Section 1.07 Issuance in Global Form. The Notes shall be issued as one or more Global Notes, representing the aggregate principal amount of the Notes, and shall be deposited with the Trustee as custodian for the Depositary. The Notes shall be registered in the name of Cede & Co., or other nominee of the Depositary.

Section 1.08 Other Terms Of Notes. The other terms of the Notes shall be as expressly set forth in Article 1, Article 2, Article 4 and Article 5 hereof and Exhibit A hereto.

The words “herein”, “hereof” and “hereunder” and other words of similar import refer to this Fourth Supplemental Indenture as a whole and not to any particular Article, Section or other subdivision.

Section 1.09 Additional Definitions. For purposes of this Fourth Supplemental Indenture, the following terms shall have the following definitions:

“Calculation Date” means, with respect to any Redemption Date, the third Business Day immediately preceding the Redemption Date.

“Comparable Treasury Issue” means the U.S. Treasury security selected by the Independent Investment Banker as having a maturity comparable to the remaining term (“Remaining Life”) of the Notes to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the Remaining Life.

“Comparable Treasury Price” means, with respect to any Redemption Date, (1) the average of five Reference Treasury Dealer Quotations for such Redemption Date, after excluding the highest and lowest Reference Treasury Dealer Quotations, or (2) if the Independent Investment Banker obtains fewer than four such Reference Treasury Dealer Quotations, the average of all such Reference Treasury Dealer Quotations.

“Depositary” means The Depository Trust Company, 00 Xxxxx Xxxxxx, Xxx Xxxx, Xxx Xxxx.

“Global Note” means a Security that evidences all or part of the Notes and bears the legend set forth in the Form of Note attached hereto as Exhibit A.

“Independent Investment Banker” means Banc of America Securities LLC, X.X. Xxxxxx Securities Inc. or Xxxxx Fargo Securities, LLC, as specified by the Company, or, if these firms are unwilling or unable to select the Comparable Treasury Issue, an independent investment banking institution of national standing appointed by the Company.

“Interest Payment Date” has the meaning set forth in Section 1 of the Form of Note attached hereto as Exhibit A.

“Reference Treasury Dealer” means (1) Banc of America Securities LLC, X.X. Xxxxxx Securities Inc. and a Primary Treasury Dealer selected by Xxxxx Fargo Securities, LLC and their respective successors, provided, however, that if any of the foregoing shall cease to be a primary U.S. government securities dealer in New York City (a “Primary Treasury Dealer”), the Company will substitute therefor another Primary Treasury Dealer and (2) any three other Primary Treasury Dealers selected by the Company after consultation with the Independent Investment Banker.

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any Redemption Date, the average, as determined by the Independent Investment Banker, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Independent Investment Banker at 5:00 p.m., New York City time, on the third Business Day preceding such Redemption Date.

“Regular Record Date” means the close of business on each of May 1, and November 1, of each year whether or not such day is a Business Day.

“Restricted Subsidiary” means each present or future Subsidiary of the Company, the consolidated total assets of which constitute at least fifteen percent of the Company’s total consolidated assets, together with each successor to any such Subsidiary; each such Subsidiary as of the date hereof being listed in Schedule 1 to this Fourth Supplemental Indenture.

“Treasury Rate” means, with respect to any Redemption Date, (i) the yield, under the heading which represents the average for the week immediately preceding the Calculation Date, appearing in the most recently published statistical release designated “H.15(519)” or any successor publication which is published weekly by the Board of Governors of the Federal Reserve System and which establishes yields on actively traded U.S. Treasury securities adjusted to constant maturity under the caption “Treasury Constant Maturities,” for the maturity corresponding to the Comparable Treasury Issue (if no maturity is within three months before or after the Remaining Life, yields for the two published maturities most closely corresponding to the Comparable Treasury Issue will be determined and the Treasury Rate will be interpolated or extrapolated from such yields on a straight line basis, rounding to the nearest month); or (ii) if such release (or any successor release) is not published during the week immediately preceding the Calculation Date or does not contain such yields, the rate per annum equal to the semiannual equivalent yield to maturity of the Comparable Treasury Issue, calculated using a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such Redemption Date.

“voting stock” has the meaning as that term is defined under the definition of “Subsidiary” under Section 101 of the Indenture.

ARTICLE 7

Defeasance and Covenant Defeasance

Section 7.01 Company’s Option to Effect Defeasance or Covenant Defeasance. The Company may elect, at its option at any time, to have Section 7.02 or Section 7.03 applied to the Notes (as a whole and not in part) upon compliance with the conditions set forth below in this Article. Any such election shall be evidenced by a Board Resolution.

Section 7.02 Defeasance and Discharge. Upon the Company’s exercise of its option to have this Section applied to the Notes (as a whole and not in part), the Company shall be deemed to have been discharged from its obligations with respect to the Notes as provided in this Section on and after the date the conditions set forth in Section 7.04 are satisfied (hereinafter called “Defeasance”). For this purpose, such Defeasance means that the Company shall be deemed to have paid and discharged the entire indebtedness represented by the Notes and to have satisfied all its other obligations under the Notes, this Fourth Supplemental Indenture and the Indenture insofar as the Notes are concerned (and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging the same), subject to the following which shall survive until otherwise terminated or discharged hereunder: (1) the rights of Holders of Notes to receive, solely from the trust fund described in Section 7.04 and as more fully set forth in such Section, payments in respect of the principal of, premium, if any, and interest on the Notes when payments are due, (2) the Company’s obligations with respect to the Notes under Sections 304, 305, 306, 1002 and 1003 of the Indenture, (3) the rights, powers, trusts, duties and immunities of the Trustee hereunder and (4) this Article.

Upon the Company’s exercise of its option to have this Section applied to the Notes (as a whole and not in part), (i) the Company shall be released from its obligations under Section 3.01 of this Fourth Supplemental Indenture and any covenant provided pursuant to Section 901(2) of the Indenture for the benefit of the Holders of the Notes and (ii) the occurrence of any event specified in Section 501(4) of the Indenture (with respect to Section 3.01 of this Fourth Supplemental Indenture and any such covenants provided pursuant to Section 901(2) of the Indenture for the benefit of the Holders of the Notes) or Section 501(8) of the Indenture added by Section 5.02 of this Fourth Supplemental Indenture, shall be deemed not to be or result in an Event of Default, in each case with respect to the Notes as provided in this Section on and after the date the conditions set forth in Section 7.04 are satisfied (hereinafter called “Covenant Defeasance”). For this purpose, such Covenant Defeasance means that, with respect to the Notes, the Company may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such specified Section (to the extent so specified in the case of Section 501(4) or 501(8) of the Indenture), whether directly or indirectly, by reason of any reference elsewhere herein to any such Section or by reason of any reference in any such Section to any other provision herein or in any other document, but the remainder of the Indenture, this Fourth Supplemental Indenture and the Notes shall be unaffected thereby.

Section 7.04 Conditions to Defeasance or Covenant Defeasance. The following shall be the conditions to the application of Section 7.02 or Section 7.03 to the Notes:

(a) The Company shall irrevocably have deposited or caused to be deposited with the Trustee (or another trustee which satisfies the requirements contemplated by Section 609 of the Indenture and agrees to comply with the provisions of this Article applicable to it) as trust funds in trust for the purpose of making the following payments, specifically pledged as security for, and dedicated solely to, the benefits of the Holders of the Notes, (A) money in an amount, or (B) U.S. Government Obligations which through the scheduled payment of principal and interest in respect thereof in accordance with their terms will provide, not later than one day before the due date of any payment, money in an amount, or (C) a combination thereof, in each case sufficient, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, to pay and discharge, and which shall be applied by the Trustee (or any such other qualifying trustee) to pay and discharge, the principal of, premium, if any, and any installment of interest on the Notes on the respective Stated Maturities, in accordance with the terms of the Indenture, this Fourth Supplemental Indenture and the Notes. As used herein, “U.S. Government Obligation” means (x) any security which is (i) a direct obligation of the

United States of America for the payment of which the full faith and credit of the United States of America is pledged or (ii) an obligation of a Person controlled or supervised by and acting as an agency or instrumentality of the United States of America the payment of which is unconditionally guaranteed as a full faith and credit obligation by the United States of America, which, in either case (i) or (ii), is not callable or redeemable at the option of the issuer thereof, and (y) any depositary receipt issued by a bank (as defined in Section 3(a) (2) of the Securities Act) as custodian with respect to any U.S. Government Obligation which is specified in clause (x) above and held by such bank for the account of the holder of such depositary receipt, or with respect to any specific payment of principal of or interest on any U.S. Government Obligation which is so specified and held, provided that (except as required by law) such custodian is not authorized to make any deduction from the amount payable to the holder of such depositary receipt from any amount received by the custodian in respect of the U.S. Government Obligation or the specific payment of principal or interest evidenced by such depositary receipt.

(b) In the event of an election to have Section 7.02 apply to the Notes, the Company shall have delivered to the Trustee an Opinion of Counsel stating that (A) the Company has received from, or there has been published by, the Internal Revenue Service a ruling or (B) since the date of this instrument, there has been a change in the applicable federal income tax law, in either case to the effect that, and based thereon such opinion shall confirm that, the Holders of the Notes will not recognize gain or loss for federal income tax purposes as a result of the deposit, Defeasance and discharge to be effected with respect to the Notes and will be subject to federal income tax on the same amount, in the same manner and at the same times as would be the case if such deposit, Defeasance and discharge were not to occur.

(c) In the event of an election to have Section 7.03 apply to the Notes, the Company shall have delivered to the Trustee an Opinion of Counsel to the effect that the Holders of the Notes will not recognize gain or loss for federal income tax purposes as a result of the deposit and Covenant Defeasance to be effected with respect to the Notes and will be subject to federal income tax on the same amount, in the same manner and at the same times as would be the case if such deposit and Covenant Defeasance were not to occur.

(d) No event which is, or after notice or lapse of time or both would become, an Event of Default with respect to the Notes shall have occurred and be continuing at the time of such deposit or, with regard to any such event specified in Sections 501(5) and (6) of the Indenture, at any time on or prior to the 90th day after the date of such deposit (it being understood that this condition shall not be deemed satisfied until after such 90th day).

(e) Such Defeasance or Covenant Defeasance shall not cause the Trustee to have a conflicting interest within the meaning of the Trust Indenture Act with respect to any securities of the Company.

(f) Such Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a default under, any other agreement or instrument to which the Company is a party or by which it is bound.

(g) The Company shall have delivered to the Trustee an Opinion of Counsel (which opinion may be subject to customary assumptions and exceptions) to the effect that after the 91st day following the deposit, the trust funds will not be subject to the effect of any applicable bankruptcy, insolvency, reorganization or similar laws affecting creditors’ rights generally.

(h) The Company shall have delivered to the Trustee an Officer’s Certificate stating that the deposit was not made by the Company with the intent of preferring the Holders of the Notes over the other creditors of the Company with the intent of defeating, hindering, delaying or defrauding creditors of the Company or others.

(i) No event or condition shall exist that would prevent the Company from making payments of the principal of, premium, if any, and interest on the Notes on the date of such deposit or at any time ending on the 91st day after the date of such deposit.

(j) Such Defeasance or Covenant Defeasance shall not result in the trust arising from such deposit constituting an investment company within the meaning of the Investment Company Act of 1940, as amended, unless such trust shall be registered under such Act or exempt from registration thereunder.

(k) The Company shall have delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that all conditions precedent under this Fourth Supplemental Indenture to either Defeasance or Covenant Defeasance, as the case may be, have been complied with.

Section 7.05 Deposited Money and U.S. Government Obligations to Be Held in Trust; Miscellaneous Provisions. Subject to the provisions of the last paragraph of Section 1003 of the Indenture, all money and U.S. Government Obligations (including the proceeds thereof) deposited with the Trustee or other qualifying trustee (solely for purposes of this Section and Section 7.06, the Trustee and any such other trustee are referred to collectively as the “Trustee”) pursuant to Section 7.04 in respect of the Notes shall be held in trust and applied by the Trustee, in accordance with the provisions of the Notes, this Fourth Supplemental Indenture and the Indenture, to the payment, either directly or through any such Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may determine, to the Holders of the Notes, of all sums due and to become due thereon in respect of principal and any premium and interest, but money so held in trust need not be segregated from other funds except to the extent required by law.

The Company shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the U.S. Government Obligations deposited pursuant to Section 7.04 or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of Notes.

Anything in this Article to the contrary notwithstanding, the Trustee shall deliver or pay to the Company from time to time upon Company Request any money or U.S. Government Obligations held by it as provided in Section 7.04 with respect to the Notes which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, are in excess of the amount thereof which would then be required to be deposited to effect the Defeasance or Covenant Defeasance, as the case may be, with respect to the Notes.

Section 7.06 Reinstatement. If the Trustee or the Paying Agent is unable to apply any money in accordance with this Article with respect to any Note by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the obligations under the Indenture, this Fourth Supplemental Indenture and the Notes from which the Company has been discharged or released pursuant to Section 7.02 or 7.03 shall be revived and reinstated as though no deposit had occurred pursuant to this Article with respect to such Note, until such time as the Trustee or Paying Agent is permitted to apply all money held in trust pursuant to Section 7.05 with respect to such Note in accordance with this Article; provided, however, that if the Company makes any payment of principal of or any premium or interest on any such Note following such reinstatement of its obligations, the Company shall be subrogated to the rights (if any) of the Holders of such Note to receive such payment from the money so held in trust.

Capitalized terms used herein shall have the meanings assigned to them in the Indenture referred to below unless otherwise indicated.

1. INTEREST. HCC Insurance Holdings, Inc., a Delaware corporation (the “Company”) promises to pay interest on the principal amount of the Notes at 6.300% per annum until the principal amount of the Notes is paid or made available for payment. The Company shall pay interest, semi-annually in arrears on May 15 and November 15, of each year, or if any such day is not a Business Day, on the next succeeding Business Day (each an “Interest Payment Date”), commencing on May 15, 2010. Interest on the Notes will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from November 16, 2009. The Company shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal from time to time on demand at a rate equal to the per annum rate on the Notes then in effect; it shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest (without regard to any applicable grace periods) from time to time on demand at the same rate to the extent lawful. Interest will be computed on the basis of a 360-day year of twelve 30-day months.

2. METHOD OF PAYMENT. Except as provided below, interest will be paid (i) on any Global Notes to DTC by wire transfer of immediately available funds to the account of DTC or its nominee and (ii) on any definitive Notes (A) by check mailed or delivered to the Holders of the Notes at their respective addresses set forth in the Security Register or (B) by wire transfer of immediately available funds to an account previous specified in writing by the Holder to the Company and the Trustee.

The Company may pay interest, including interest payable at Stated Maturity, on definitive Notes at the Company’s office or agency in the Borough of Manhattan, The City of New York, which initially will be the Corporate Trust Office of the Trustee in The City of New York.

Principal on definitive Notes will be payable, upon Stated Maturity or when due, at the office or agency of the Company in Borough of Manhattan, The City of New York, maintained for such purpose, initially the Corporate Trust Office of the Trustee in The City of New York.

Subject to the terms and conditions of the Indenture, the Company will make payments in cash in respect of Redemption Prices and at Stated Maturity to Holders who surrender Notes to a Paying Agent to collect such payments in respect of the Notes. The Company will pay cash amounts in money of the United States that at the time of payment is legal tender for payment of public and private debts.

3. PAYING AGENT AND SECURITY REGISTRAR. Initially, U.S. Bank National Association will act as Paying Agent and Security Registrar. The Company may appoint and change any Paying Agent, Security Registrar or co-registrar without notice, other than notice to the Trustee, except that the Company will maintain at least one Paying Agent in the State of New York, City of New York, Borough of Manhattan, which shall initially be an office or agency of the Trustee. The Company or any of its Subsidiaries or any of their Affiliates may act as Paying Agent, Conversion Agent, Security Registrar or co-registrar.

4. INDENTURE. The Company issued the Notes under an Indenture, dated as of August 23, 2001 (the “Base Indenture”), as supplemented by the Fourth Supplemental Indenture dated as of November 16, 2009 (the “Fourth Supplemental Indenture” and, together with the Base Indenture, the “Indenture”), between the Company and U.S. Bank National Association, as trustee (the “Trustee”). 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. The Notes are subject to all such terms, and Holders are referred to the Indenture and such Act for a statement of such terms. The Notes issued under the Indenture are general unsecured obligations of the Company limited to $300,000,000 in aggregate principal amount.

5. OPTIONAL REDEMPTION. At any time and from time to time, the Company may redeem in cash any portion of the Notes, in whole or in part, at a Redemption Price equal to the greater of (a) the principal amount of the Notes or (b) the sum of the present values of the remaining scheduled payments of principal

and interest on the Notes to be redeemed (not including any portion of such payments of interest accrued to the date of redemption) discounted to the date of redemption on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the applicable Treasury Rate plus 50 basis points, plus, in each case (a) and (b), accrued and unpaid interest on the principal amount of the Notes being redeemed to but excluding the date of redemption (the “Redemption Price”). The date of any such redemption is known as the “Redemption Date”. The Treasury Rate will be calculated on the third Business Day immediately preceding the Redemption Date.

As used in this Note the following terms have the definitions set forth herein:

“Calculation Date” means, with respect to any Redemption Date, the third Business Day immediately preceding the Redemption Date.

“Comparable Treasury Issue” means the U.S. Treasury security selected by the Independent Investment Banker as having a maturity comparable to the remaining term (“Remaining Life”) of the Notes to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the Remaining Life.

In the event the Company redeems less than all of the outstanding Notes, the Notes to be redeemed shall be selected by the Trustee in accordance with Section 1103 of the Indenture. The Company may not give notice of any redemption if the Company has defaulted in payment of interest and the default is continuing.

6. NOTICE OF REDEMPTION. Notice of redemption will be mailed at least 30 days but not more than 60 days before the Redemption Date to each Holder of the Notes to be redeemed at such Holder’s address of record. The Notes in denominations larger than $1,000 may be redeemed in part but only in integral multiples of $1,000. On and after redemption of a Note pursuant to Section 5 and 6, interest shall cease to accrue on such Note.

7. NO MANDATORY REDEMPTION. The Company shall not be required to make mandatory redemption payments with respect to the Notes. There are no sinking fund payments with respect to the Notes.

8. DENOMINATIONS; TRANSFER; EXCHANGE. The Notes are in registered form without coupons in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof. The transfer of Notes may be registered and Notes may be exchanged as provided in the Indenture. The Security Registrar may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay any taxes and fees required by law or permitted by the Indenture.

9. PERSONS DEEMED OWNERS. The registered Holder of this Note may be treated as its owner for all purposes.

10. AMENDMENT, SUPPLEMENT AND WAIVER. Subject to certain exceptions set forth in the Indenture, (i) the Fourth Supplemental Indenture or the Notes may be amended with the written consent of the Holders of a majority in aggregate principal amount of the Notes at the time outstanding and (ii) certain defaults under the Fourth Supplemental Indenture or the Notes may be waived with the written consent of the Holders of a majority in aggregate principal amount of the Notes at the time outstanding. Without the consent of any Holder of the Notes, the Fourth Supplemental Indenture or the Notes may be amended or supplemented, in addition to other events more fully described in the Indenture, to cure any ambiguity, defect or inconsistency, to establish the form or terms of the Securities, to evidence the succession of another corporation to the Company and the assumption by any such successor of the covenants of the Company contained in the Indenture, to secure the Securities, and to make any change that does not materially adversely affect the interests of any Holder under the Indenture.

11. DEFAULTS AND REMEDIES. If any Event of Default with respect to the Notes shall occur and be continuing, the principal of all the Notes may be declared due and payable in the manner and with the effect provided in the Indenture.

12. TRUSTEE DEALINGS WITH COMPANY. Subject to certain limitations imposed by the Trust Indenture Act, the Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Notes and may otherwise deal with and collect obligations owed to it by the Company or its Affiliates and may otherwise deal with the Company or its Affiliates with the same rights it would have if it were not Trustee.

13. NO RECOURSE AGAINST OTHERS. A director, officer, employee, incorporator or shareholder of the Company, as such, shall not have any liability for any obligations of the Company under the Notes or the Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder by accepting a Note waives and releases all such liability including any rights against any such person in its capacity relating to the Company. The waiver and release are part of the consideration for the issuance of the Notes.

14. AUTHENTICATION. This Security shall not be valid until authenticated by the manual signature of the Trustee or an authenticating agent.

15. ABBREVIATIONS. Customary abbreviations may be used in the name of a Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT (= tenants by the entireties), JT TEN (= joint tenants with right of survivorship and not as tenants in common), CUST (= Custodian), and U/G/M/A (=Uniform Gifts to Minors Act).

16. CUSIP NUMBERS. Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Company has caused CUSIP numbers to be printed on the Notes and the Trustee may use CUSIP numbers in notices of redemption as a convenience to Holders. No representation is made as to the accuracy of such numbers either as printed on the Notes or as contained in any notice of redemption and reliance may be placed only on the other identification numbers placed thereon.

17. UNCLAIMED MONEY OR SECURITIES. The Trustee and the Paying Agent shall return to the Company upon written request any money or securities held by them for the payment of any amount with respect to the Notes that remains unclaimed for three years, subject to applicable laws. After return to the Company, Holders entitled to the money or securities must look to the Company for payment as general creditors, subject to applicable laws.

18. DEFEASANCE. Subject to certain conditions set forth in the Indenture, the Company at any time may terminate some or all of its obligations under the Notes and the Fourth Supplemental Indenture if the Company deposits with the Trustee money or U.S. Government Obligations for payment of principal and interest on the Notes to the Stated Maturity.

19. GOVERNING LAW. THE INDENTURE AND THE NOTES WILL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.
