DESCRIPTION OF MATERIAL INDEBTEDNESS

We summarize below selected provisions of our material loan agreements, indentures and guarantees. The summary is not complete and does not describe every aspect of the loan agreements, indentures or guarantees. Copies of the credit agreements, indentures and guarantees are available upon request. You should read the credit agreements, indentures and the guarantees in their entirety, including the defined terms, for provisions that may be important to you.

Credit Facilities

2020 Credit Facility

On April 3, 2020, we entered into a credit agreement with the lenders party thereto, and JPMorgan Chase Bank, N.A., as administrative agent, that established a $500 million revolving credit facility (the “2020 Credit Facility”). The 2020 Credit Facility matures on April 2, 2021. As of September 30, 2020, no borrowings were outstanding under the 2020 Credit Facility.

Interest Rates. The 2020 Credit Facility has a variable interest rate on outstanding borrowings based on the London Interbank Offered Rate (“LIBOR”) plus a spread based upon our credit rating, which may vary between 2.00% and 2.375%. The revolving credit facility also has a commitment fee rate on the unutilized balance of 0.50%.

Covenants. The 2020 Credit Facility contains affirmative and negative covenants customary for an unsecured credit facility, as well as a financial covenant based on a maximum total leverage ratio. Each of our existing and future material wholly owned domestic subsidiaries, except those that are specifically designated as unrestricted subsidiaries or immaterial subsidiaries, are and will be guarantors under the 2020 Credit Facility.

Events of Default. Our 2020 Credit Facility contains customary events of default and remedies provisions.

2017 Credit Facility

On November 22, 2017, we entered into a credit agreement (the “2017 Credit Facility”) with the lenders party thereto, JPMorgan Chase Bank, N.A., as administrative agent and an issuing bank, and certain other issuing banks. Our 2017 Credit Facility is comprised of a revolving credit facility of $1.250 billion, which may be drawn upon during a period of five years from the date of the 2017 Credit Facility. Our 2017 Credit Facility includes a letter of credit subfacility of $500 million. In addition, our 2017 Credit Facility permits us to solicit lenders to provide incremental revolving loan commitments, up to two new tranches of revolving credit facilities and/or new tranches of term loans in an aggregate amount not to exceed $1.0 billion.

Interest Rates. The 2017 Credit Facility has a variable interest rate on outstanding borrowings, which is generally based on the LIBOR plus a spread based upon our credit rating, which may vary between 1.125% and 1.50%. The 2017 Credit Facility also has a commitment fee rate on the unutilized balance based upon our credit rating. The commitment fee rate as of September 30, 2020 was 0.25% and may vary between 0.20% and 0.30%. As of September 30, 2020, approximately $16 million in letters of credit were issued but undrawn, and the remaining $1.234 billion of the 2017 Credit Facility was unutilized.

Covenants. Our 2017 Credit Facility requires that we comply with customary affirmative covenants, including, but not limited to, those related to our maintaining our corporate existence, complying with applicable laws, payment of taxes, maintaining books and records, ownership of property, employee benefits, compliance with environmental laws, designation of subsidiaries and our maintaining a separate existence between us and our wholly owned subsidiary Titan II Inc., a Delaware corporation. Our 2017 Credit Facility also includes customary negative covenants, which include, but are not limited to, limitations on incurrence of indebtedness,

liens, sale and leaseback transactions, sales of assets, mergers, consolidations, liquidations and dissolutions, dividends and changes in lines of business. In addition, our 2017 Credit Facility requires that we not exceed a maximum total leverage ratio.

Events of Default. Our 2017 Credit Facility contains customary events of default and remedies provisions.

5.000% Senior Notes due 2025

In November 2015, we issued $600 million aggregate principal amount of 5.000% Senior Notes due 2025 (the “5.000% 2025 Notes”), all of which were outstanding as of September 30, 2020. On October 16, 2020, we called for redemption on November 15, 2020 all of the outstanding 5.000% 2025 Notes.

3.483% Senior Notes due 2027

In November 2017, we issued $600 million aggregate principal amount of 3.483% Senior Notes due 2027 (the “2027 Notes”).

Covenants. The terms of the 2027 Notes include limitations on the ability of us and certain of our subsidiaries to create liens, enter into certain sale and leaseback transactions or effect a consolidation or merger.

Guarantees. Performance of our obligations under the 2027 Notes, including any repurchase obligations resulting from a change of control, has been fully and unconditionally guaranteed, jointly and severally, on an unsecured basis, by each of our existing and future domestic subsidiaries that guarantees, and each of our wholly owned domestic subsidiaries that incurs, debt under our Credit Facilities, any credit facility that replaces the Credit Facilities, or any credit facility, note purchase agreement or indenture, or any agreement that refinances debt incurred under any of the foregoing, as will any wholly owned domestic subsidiary that guarantees or incurs debt in the future under any such credit facility, note purchase agreement, indenture or other agreement (the “Subsidiary Guarantors”). The guarantees rank equally in right of payment with all other unsecured and unsubordinated indebtedness of the Subsidiary Guarantors. The Subsidiary Guarantors are each directly or indirectly 100% owned by us. There are no significant restrictions on our ability or the ability of any Subsidiary Guarantor to obtain funds from their respective subsidiaries by dividend or loan.

Optional Redemption. At any time and from time to time prior to September 1, 2027, we may redeem, in whole or in part, the 2027 Notes at a price of 100% of the principal amount of the 2027 Notes redeemed, plus a “make-whole” premium, plus accrued and unpaid interest, if any, to, but excluding, the redemption date. On and after September 1, 2027, we may redeem some or all of the Notes at a price equal to 100% of the principal amounts of the Notes being redeemed, plus accrued and unpaid interest, if any, to, but excluding, the redemption date.

Change of Control. Upon the occurrence of certain events constituting a change of control, we are required, no later than 30 days following the change of control, to make an offer to purchase all of the outstanding 2027 Notes (unless otherwise redeemed or if a third party makes an offer to purchase the Notes contemporaneously with the change of control) at a purchase price equal to 101% of their principal amount, plus accrued and unpaid interest, if any, to, but excluding, the date of purchase.

Events of Default. The occurrence of an event of default under the 2027 Notes would permit or require the principal of and accrued and unpaid interest on the 2027 Notes to become or to be declared due and payable. Events of default under the indenture include nonpayment of principal or interest when due; violation of covenants and other agreements contained in the indenture governing the 2027 Notes; cross payment default and cross acceleration of certain material debt; certain bankruptcy and insolvency events and material judgment defaults, among others.

Mississippi Economic Development Revenue Bonds

As of September 30, 2020, we had $84 million outstanding under Industrial Revenue Bonds (the “Mississippi IRBs”) issued by the Mississippi Business Finance Corporation. These bonds accrue interest at a fixed rate of 7.81% and mature in 2024. While repayment of principal and interest is guaranteed by Northrop Grumman Systems Corporation, we have agreed to indemnify Northrop Grumman Systems Corporation for any losses related to the guaranty. In accordance with the terms of the bonds, the proceeds have been used to finance the construction, reconstruction, and renovation of our interest in certain ship manufacturing and repair facilities, or portions thereof, located in the state of Mississippi. The terms of the Mississippi IRBs contain customary affirmative and negative covenants, including those requiring that we: maintain our corporate existence, maintain and properly insure certain buildings and immovable equipment at our shipbuilding complex located in Jackson County, Mississippi (collectively, the “Ingalls Project”) and promptly pay when due all taxes and assessments related to the Ingalls Project.

Gulf Opportunity Zone Industrial Development Revenue Bonds

As of September 30, 2020, we had $21 million outstanding under Gulf Opportunity Zone Industrial Development Revenue Bonds (“Go Zone IRBs”) issued by the Mississippi Business Finance Corporation. These bonds accrue interest at a fixed rate of 4.55% and mature in 2028. The terms of the Go Zone IRBs include customary affirmative and negative covenants, including those requiring that we: maintain our corporate existence, maintain and properly insure certain buildings and immovable equipment at our shipbuilding complex located in Pascagoula and Gulfport, Mississippi (collectively, the “GO Zone Project”), promptly pay when due all taxes and assessments related to the Go Zone Project, and operate and maintain the GO Zone Project for so long as the GO Zone IRBs remain outstanding.

DESCRIPTION OF THE NOTES

The Old Notes were issued on March 30, 2020 in private offerings in the United States only to qualified institutional buyers under Rule 144A under the Securities Act and outside the United States to non-U.S. persons in compliance with Regulation S under the Securities Act.

In the exchange offer, we will issue up to $500,000,000 aggregate principal amount of New 2025 Notes and up to $500,000,000 aggregate principal amount of New 2030 Notes. The New Notes will be issued under the indenture dated March 30, 2020 by and among Huntington Ingalls Industries, Inc., the subsidiary guarantors party thereto and Wells Fargo Bank, National Association, as trustee (the “indenture”), under which the Old Notes were also issued. In this “Description of the Notes,” “HII” refers only to Huntington Ingalls Industries, Inc. and any successor obligor on the Old Notes and New Notes, and, unless the context otherwise requires, not to any of its subsidiaries. You can find the definitions of certain terms used in this description under “—Certain Definitions.” The term “Notes,” as used in this “Description of the Notes,” refers to both the Old Notes and the New Notes, and, as applicable, any Notes issued in the future under the indenture.

The New Notes of each series will be treated as a single class with the Old Notes of the corresponding series that remain outstanding after the completion of the exchange offer. If the exchange offer is consummated, holders of Old Notes of a series who do not exchange their Old Notes for New Notes will vote together with the holders of the New Notes of such series for all relevant purposes under the indenture. In that regard, the indenture requires that certain actions by the holders under the indenture (including acceleration after an Event of Default) must be taken, and certain rights must be exercised, by holders of specified minimum percentages of the aggregate principal amount of all outstanding Notes of a series issued under the indenture. In determining whether holders of the requisite percentage of aggregate principal amount of Notes of a series have given any notice, consent or waiver or taken any other action permitted under the indenture, any Old Notes of a series that remain outstanding after the exchange offer will be aggregated with the New Notes of that series, and the holders of these Old Notes and New Notes will vote together as a single class for all such purposes. Accordingly, all references in this “Description of the Notes” to specified percentages in aggregate principal amount of outstanding Notes mean, at any time after the exchange offer for the Old Notes is consummated, such percentage in aggregate principal amount of such Old Notes of a series and the New Notes of such series then outstanding.

The following is a summary of the material provisions of the indenture. Because this is a summary, it may not contain all the information that is important to you. You should read the indenture in its entirety. Copies of the indenture are available as described under “Where You Can Find More Information” and “Incorporation by Reference.”

Basic Terms of Notes

The New 2025 Notes will mature on May 1, 2025. The New 2030 Notes will mature on May 1, 2030. The Old Notes are, and the New Notes will be, unsecured unsubordinated obligations of HII, ranking equally in right of payment with all existing and future unsubordinated obligations of HII. The Old Notes bear interest from March 30, 2020 or the immediately preceding interest payment date to which interest has been paid or duly provided for, and the New Notes will bear interest from the date of issue at a rate of 3.844% per annum in the case of the New 2025 Notes and at a rate of 4.200% per annum in the case of the New 2030 Notes, payable in each case semiannually on each May 1 and November 1, to holders of record of the applicable series of New Notes on the April 15 or October 15 (whether or not a business day) immediately preceding the interest payment date. Interest will be computed on the basis of a 360-day year of twelve 30-day months.

Additional Notes

Subject to the covenants described below, HII may issue additional Notes under the indenture having the same terms in all respects as the Notes, or in all respects except with respect to interest paid or payable on or

- 30 -

prior to the first interest payment date after the issuance of additional Notes, and such additional Notes may have different issuance prices, initial interest accrual dates or initial interest payment dates and may not have the benefit of any registration rights. The Old Notes, the New Notes issued in the exchange offer and any additional Notes subsequently issued would be treated as a single class for all purposes under the indenture and will vote together as one class on all matters with respect to the Notes, provided that if the additional Notes are not fungible with the Notes offered hereby for United States federal income tax purposes, the additional Notes will have a separate CUSIP number.

Guarantees

The obligations of HII pursuant to the Notes, including any repurchase obligations resulting from a Change of Control Triggering Event, will be unconditionally guaranteed, jointly and severally, on an unsecured basis, by each of HII’s direct and indirect Domestic Subsidiaries that Guarantees Debt under the Credit Agreement. In addition, if any Wholly Owned Domestic Subsidiary Guarantees Debt under any Credit Facility or Capital Markets Debt after the Issue Date, such Wholly Owned Domestic Subsidiary must also Guarantee the Notes; provided that no Subsidiary that has been designated an Unrestricted Subsidiary for purposes of the Credit Agreement or is an Immaterial Subsidiary under the Credit Agreement shall be required to provide such Note Guaranty. Each of HII’s subsidiaries that is not a Guarantor is considered to be “minor” (as defined in Rule 3-10(h) of Regulation S-X), and HII, as parent company issuer, does not have independent assets or operations. There are no significant restrictions on the ability of HII and its Guarantor Subsidiaries to obtain funds from HII’s subsidiaries by dividend or loan, except those imposed by applicable law.

Each Note Guaranty will be limited to the maximum amount that would not render the applicable Guarantor’s obligations subject to avoidance under applicable fraudulent conveyance provisions of the United States Bankruptcy Code or any comparable provision of state law. By virtue of this limitation, a Guarantor’s obligation under its Note Guaranty could be significantly less than amounts payable with respect to the Notes, or a Guarantor may have effectively no obligation under its Note Guaranty. See “Risk Factors—Risks Relating to the Notes—Insolvency and fraudulent transfer laws and other limitations may preclude the recovery of payment under the Notes and the guarantees.”

The Note Guaranty of a Guarantor will terminate upon

(1) a sale or other disposition (including by way of consolidation or merger) of Capital Stock of the Guarantor if, as a result of such disposition, such Guarantor ceases to be a Subsidiary or the sale or disposition of all or substantially all the assets of the Guarantor (other than to HII or a Subsidiary) is otherwise permitted by the indenture,

(2) the release or discharge of the Guarantee by such Guarantor of Debt under each Credit Facility to which it is a party or becomes a party after the Issue Date, other than a discharge through payment under such Guarantee, or

(3) defeasance or discharge of the Notes, as provided in “—Defeasance and Discharge.”

Optional Redemption

The Notes will be redeemable, in whole or in part, at the option of HII, at any time and from time to time, with respect to the 2025 Notes, prior to April 1, 2025 (one month prior to the maturity of the New 2025 Notes) and, in the case of the 2030 Notes, at any time prior to February 1, 2030 (three months prior to the maturity of the New 2030 Notes) (each such date, a “Par Call Date”), upon not less than 15 nor more than 60 days’ notice, at a price equal to the greater of:

- 31 -

provided, that if HII redeems any Notes on or after the applicable Par Call Date, the redemption price for such Notes will equal 100% of the principal amount of the Notes to be redeemed.

The redemption price for the Notes will include, in each case, accrued and unpaid interest, if any, to, but excluding, the applicable redemption date on the principal amount of Notes to be redeemed (subject to the right of the holders of record on the relevant regular record date to receive interest due on an interest payment date that is on or prior to such redemption date).

HII may at any time, and from time to time, purchase Notes in the open market or otherwise.

Selection and Notice

If fewer than all of the Notes of a particular series are being redeemed, the trustee will select the Notes of that series to be redeemed, by lot or by any other method the trustee in its sole discretion deems appropriate, in denominations of $2,000 principal amount and integral multiples of $1,000 in excess thereof; provided, that if the Notes of a particular series are represented by one or more global notes, beneficial interests in the Notes of that series will be selected for redemption by DTC in accordance with its standard procedures therefor. Upon surrender of any Note redeemed in part, the holder will receive a new Note equal in principal amount to the unredeemed portion of the surrendered Note. Once notice of redemption is sent to the holders, Notes called for redemption become due and payable at the redemption price on the redemption date. Commencing on the redemption date, Notes redeemed will cease to accrue interest.

No Mandatory Redemption or Sinking Fund

There will be no mandatory redemption or sinking fund payments for the Notes.

Ranking

The New Notes of each series and the related Note Guarantees will rank equally to each other in right of payment with or senior to all Debt of HII and the Guarantors, but will be effectively junior to all secured Debt of HII and the Guarantors to the extent of the value of the assets securing such Debt. As of September 30, 2020, we had $2.278 billion of total debt, including the Old Notes, the 5.000% 2025 Notes, the 2027 Notes, and our outstanding Mississippi IRBs and GoZone IRBs. As of September 30, 2020, we also had $1.734 billion of unutilized borrowing capacity under our Credit Facilities. Subject to the limits described under “Limitation on Liens,” HII and its Subsidiaries may incur additional secured Debt.

None of HII’s current or future Foreign Subsidiaries, Subsidiaries that are not wholly owned, Subsidiaries that are Immaterial Subsidiaries under the Credit Agreement, or Subsidiaries that are designated as Unrestricted Subsidiaries under the Credit Agreement will guarantee the Notes. Claims of creditors of non-guarantor subsidiaries, including trade creditors, and claims of preferred stockholders (if any) of those subsidiaries generally will have priority with respect to the assets and earnings of those subsidiaries over the claims of creditors of HII, including holders of the Notes. The Notes and each Note Guaranty therefore will be effectively subordinated to creditors (including trade creditors) and preferred stockholders (if any) of subsidiaries of HII that are not Guarantors. As of September 30, 2020, HII’s non-Guarantor subsidiaries had no material assets or liabilities.

The indenture does not limit the Incurrence of Debt by HII or any of its Subsidiaries, and HII and its Subsidiaries may be able to Incur substantial amounts of additional Debt, including additional secured Debt.

- 32 -

Certain Covenants

The indenture contains covenants including, among others, the following:

Limitation on Liens

HII will not, and will not permit any Restricted Subsidiary to, directly or indirectly, incur or permit to exist any Liens of any nature whatsoever that secure Debt on any Principal Property of HII or any Restricted Subsidiary, or on shares of Capital Stock or Debt issued by any Restricted Subsidiary and owned by the Company or any Restricted Subsidiary, whether the Principal Property, shares of Capital Stock or Debt were owned at the Issue Date or thereafter acquired, other than Permitted Liens, without effectively providing, substantially concurrently with or prior to the creation of such Lien, that the Notes (or, in the case of a Restricted Subsidiary that is a Guarantor, its Note Guaranty) are secured equally and ratably with (or, if the obligation to be secured by the Lien is subordinated in right of payment to the Notes or any Note Guaranty, prior to) the obligations so secured for so long as such obligations are so secured.

“Principal Property” means any manufacturing plant or warehouse, together with the land upon which it is erected and fixtures comprising a part thereof, owned by the Company or any Restricted Subsidiary and located in the United States, the gross book value of which on the date as of which the determination is being made is an amount which exceeds 2% of Consolidated Net Tangible Assets, but not including any property financed through the issuance of any tax exempt governmental obligation, or any such manufacturing plant or warehouse or any portion thereof or any such fixture (together with the land upon which it is erected and fixtures comprising a part thereof) which, in the opinion of the board of directors of HII, is not of material importance to the total business conducted by the Company and its Subsidiaries, considered as a single enterprise.

For purposes of determining compliance with this covenant, (A) a Lien securing an item of Debt need not be permitted solely by reference to one category (or portion thereof) described in the definition of “Permitted Liens,” but may be permitted in part under any combination thereof and (B) in the event that a Lien securing an item of Debt (or any portion thereof) meets the criteria of one or more of the categories (or portions thereof) of Permitted Liens, HII shall, in its sole discretion, divide, classify or reclassify, or later divide, classify, or reclassify, such Lien securing such item of Debt (or any portion thereof) in any manner that complies (based on circumstances existing at the time of such division, classification or reclassification) with this covenant.

Limitation on Sale and Leaseback Transactions

HII will not, and will not permit any Restricted Subsidiary to, enter into any Sale and Leaseback Transaction with respect to any Principal Property unless:

(1) the Sale and Leaseback Transaction is solely with HII or a Guarantor;

(2) the lease is for a period not in excess of 36 months, including renewals;

(3) HII or such Subsidiary would (at the time of entering into such arrangement) be entitled as described in clauses (1) through (27) of the definition of “Permitted Liens,” without equally and ratably securing the Notes then outstanding under the indenture, to create, Incur, issue, assume or guarantee Debt secured by a Lien on such property in the amount of the Attributable Debt arising from such Sale and Leaseback Transaction;

(4) HII or such Subsidiary within 360 days after the sale of such property in connection with such Sale and Leaseback Transaction is completed, applies an amount equal to the greater of (a) the net proceeds of the sale of such property or (b) the fair market value of such property to (i) the permanent retirement of the Notes, other Debt of HII ranking equally in right of payment with the Notes or Debt of a non-Guarantor Subsidiary or (ii) the purchase of property; or

- 33 -

(5) the Attributable Debt of HII and its Subsidiaries in respect of such Sale and Leaseback Transaction and all other Sale and Leaseback Transactions entered into after the Issue Date (other than any such Sale and Leaseback Transaction as would be permitted as described in clauses (1) through (4) above), plus the aggregate principal amount of Debt secured by Liens on properties then outstanding (not including any such Debt secured by Liens described in clauses (1) through (26) of the definition of “Permitted Liens”) which do not equally and ratably secure such outstanding Notes (or secure such outstanding Notes on a basis that is prior to other Debt secured thereby), would not exceed 15% of Consolidated Net Tangible Assets.

Repurchase of Notes upon a Change of Control Triggering Event

Not later than 30 days following a Change of Control Triggering Event or, at our option, prior to the consummation of any Change of Control but after public announcement of the transaction that constitutes or may constitute the Change of Control, HII will make an Offer to Purchase all outstanding Notes of each series at a purchase price equal to 101% of the principal amount, plus accrued and unpaid interest to, but excluding, the date of purchase.

An “Offer to Purchase” must be made by written offer, which will specify the principal amount of Notes subject to the offer and the purchase price. The offer must specify an expiration date (the “expiration date”) not less than 15 days or more than 60 days after the date of the offer and a settlement date for purchase (the “purchase date”) not more than five business days after the expiration date. The offer must describe the transaction or transactions that constitute the Change of Control Triggering Event. The offer will also contain instructions and materials necessary to enable holders to tender Notes pursuant to the offer.

A holder may tender all or any portion of its Notes pursuant to an Offer to Purchase, subject to the requirement that any portion of a Note tendered must be equal to $2,000 principal amount or a higher multiple of $1,000, provided, that any unpurchased portion of a Note must be in a minimum principal amount of $2,000. Holders are entitled to withdraw Notes tendered up to the close of business on the expiration date. On the purchase date the purchase price will become due and payable on each Note accepted for purchase pursuant to the Offer to Purchase, and interest on Notes purchased will cease to accrue on and after the purchase date.

HII will not be required to make an Offer to Purchase upon a Change of Control Triggering Event if (i) a third party makes such Offer to Purchase contemporaneously with or upon a Change of Control Triggering Event in the manner, at the times and otherwise in compliance with the requirements of the indenture and purchases all Notes validly tendered and not withdrawn under such Offer to Purchase or (ii) a notice of redemption to the holders of the Notes has been given pursuant to the indenture as described under “—Optional Redemption.”

In the event that holders of not less than 90% of the aggregate principal amount of the outstanding Notes of the applicable series of Notes accept an Offer to Purchase following a Change of Control Triggering Event and HII purchases all of the Notes of such series held by such holders, HII will have the right, upon not less than 15 nor more than 60 days’ prior notice, given not more than 30 days following the purchase pursuant to the Offer to Purchase described above, to redeem all of the Notes of such series that remain outstanding following such purchase at a redemption price equal to 101% of the aggregate principal amount of Notes redeemed, plus accrued and unpaid interest, if any, thereon to, but excluding, the date of redemption, subject to the right of the holders of record on the relevant regular record date to receive interest due on an interest payment date that is on or prior to such date of redemption.

HII will comply with Rule 14e-1 under the Exchange Act and all other applicable laws in making any Offer to Purchase, and the above procedures will be deemed modified as necessary to permit such compliance.

The occurrence of certain change of control events with respect to HII would constitute a default under the Credit Agreement. In the event a Change of Control Triggering Event occurs, HII could attempt to seek a waiver from the requisite lenders under the Credit Agreement or refinance the Credit Agreement. If HII were not able to refinance or obtain the requisite consents for a waiver, it would constitute an Event of Default under the Credit Agreement.

- 34 -

Future debt of HII may prohibit HII from purchasing Notes in the event of a Change of Control Triggering Event, provide that a Change of Control Triggering Event is a default or require repurchase upon a Change of Control Triggering Event. In addition, the indenture governing the 5.000% 2025 Notes and the indenture governing the 2027 Notes require that we make an offer to repurchase the 5.000% 2025 Notes and the 2027 Notes, respectively, upon the occurrence of a change of control with respect to HII. Moreover, the exercise by the Noteholders of their right to require HII to purchase the Notes could cause a default under other debt, even if the Change of Control Triggering Event itself does not, due to the financial effect of the purchase on HII.

Finally, HII’s ability to pay cash to the noteholders following the occurrence of a Change of Control Triggering Event may be limited by HII’s then-existing financial resources. There can be no assurance that sufficient funds will be available when necessary to make the required purchase of the Notes. See “Risk Factors—Risks Relating to the Notes—The Notes are subject to a change of control provision, and we may not have the ability to raise the funds necessary to fulfill our obligations under the Notes following a change of control triggering event.”

The phrase “all or substantially all,” as used with respect to the assets of HII in the definition of “Change of Control,” is subject to interpretation under applicable state law, and its applicability in a given instance would depend upon the facts and circumstances. As a result, there may be a degree of uncertainty in ascertaining whether a sale or transfer of “all or substantially all” the assets of HII has occurred in a particular instance, in which case a holder’s ability to obtain the benefit of these provisions could be unclear.

Except as described above with respect to a Change of Control Triggering Event, the indenture will not contain provisions that permit the holders of the Notes to require that HII purchase or redeem the Notes in the event of a takeover, recapitalization or similar transaction.

The provisions under the indenture relating to HII’s obligation to make an offer to repurchase each series of Notes as a result of a Change of Control Triggering Event may be waived or amended as described in “—Amendments and Waivers.”

Financial Reports

(a) HII shall deliver to the trustee, within 15 days after it files them with the SEC, copies of the annual reports and of the information, documents, and other reports (or copies of such portions of any of the foregoing as the SEC may by rules and regulations prescribe) which HII is required to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act. HII also shall comply with the other provisions of Section 314(a) of the Trust Indenture Act.

(b) For so long as any of the Notes remain outstanding and constitute “restricted securities” under Rule 144, HII will furnish to the holders of the Notes and prospective investors, upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act.

Reports to Trustee

HII will deliver to the trustee

(1) within 120 days after the end of each fiscal year a certificate stating that HII has fulfilled its obligations under the indenture or, if there has been a Default, specifying the Default and its nature and status; and

(2) as soon as possible and in any event within 30 days after HII becomes aware of the occurrence of a Default, an officers’ certificate setting forth the details of the Default, and the action which HII proposes to take with respect thereto.

- 35 -

Consolidation, Merger or Sale of Assets

Company

HII will not

unless:

(1) either (x) HII is the continuing Person or (y) the resulting, surviving or transferee Person is a corporation, limited liability company or partnership (provided that if the resulting, surviving or transferee Person is a limited liability company or partnership, a corporate Wholly Owned Subsidiary becomes a co-obligor at such time) organized and validly existing under the laws of the United States of America or any jurisdiction thereof and expressly assumes by supplemental indenture all of the obligations of HII under the indenture and the Notes and the registration rights agreement;

(2) immediately after giving effect to the transaction, no Default has occurred and is continuing; and

(3) HII delivers to the trustee an officers’ certificate and an opinion of counsel, each stating that the consolidation, merger or transfer and the supplemental indenture (if any) comply with the indenture;

provided, that clause (2) does not apply (i) to the consolidation or merger of HII with or into a Wholly Owned Subsidiary or the consolidation or merger of a Wholly Owned Subsidiary with or into HII, or to the sale, lease, conveyance, transfer, or other disposition of all or substantially all of its assets and the assets of its Subsidiaries, taken as a whole, as an entirety or substantially an entirety, to a Wholly Owned Subsidiary that is a Guarantor, or (ii) if the sole purpose of the transaction is to change the jurisdiction of incorporation of HII.

Upon the consummation of any transaction effected in accordance with the foregoing provisions, if HII is not the continuing Person, the resulting, surviving or transferee Person will succeed to, and be substituted for, and may exercise every right and power of, HII under the indenture and the Notes with the same effect as if such successor Person had been named as HII in the indenture. Upon such substitution, except in the case of a lease, HII will be released from its obligations under the indenture and the Notes.

Guarantors

No Guarantor may

unless:

(1) the other Person is HII or any Subsidiary that is a Guarantor or becomes a Guarantor concurrently with the transaction; or

(2) (A) either (x) the Guarantor is the continuing Person or (y) the resulting, surviving or transferee Person expressly assumes by supplemental indenture all of the obligations of the Guarantor under its Note Guaranty; and

(B) immediately after giving effect to the transaction, no Default has occurred and is continuing; or

(3) the transaction constitutes a sale or other disposition (including by way of consolidation or merger) of the Guarantor or the sale or disposition of all or substantially all the assets of the Guarantor (in each case other than to HII or a Subsidiary) otherwise permitted by the indenture.

Default and Remedies

Events of Default

An “Event of Default” will occur with respect to either series of the Notes if

(1) HII defaults in the payment of the principal of any Note when the same becomes due and payable at maturity, upon acceleration or redemption, or otherwise (other than pursuant to an Offer to Purchase pursuant to “—Repurchase of Notes upon a Change of Control Triggering Event”);

(2) HII defaults in the payment of interest (including any additional interest) on any Note when the same becomes due and payable, and the default continues for a period of 30 days;

(3) HII defaults in the performance of or breaches any other covenant or agreement of HII in the indenture or under the Notes and the default or breach continues for a period of 90 consecutive days after written notice thereof to HII by the trustee or to HII and the trustee by the holders of 25% or more in aggregate principal amount of the Notes (which notice requires that the default be remedied and states that it is a notice of default under the indenture);

(4) (i) any failure to pay indebtedness for money HII borrowed or guaranteed the payment of in an aggregate principal amount of at least $100 million at the later of Stated Maturity and the expiration of any related applicable grace period and such defaulted payment shall not have been made, waived or extended within 30 days or (ii) acceleration of the Stated Maturity of any indebtedness for money that HII borrowed or guaranteed the payment of in an aggregate principal amount of at least $100 million, if such indebtedness has not been discharged in full or such acceleration has not been rescinded or annulled within 30 days; provided, however, that, if the default under the instrument is cured by HII, or waived by the holders of the indebtedness, in each case as permitted by the governing instrument, then the event of default under the indenture governing the Notes caused by such default will be deemed likewise to be cured or waived;

(5) certain bankruptcy defaults occur with respect to HII; or

(6) any Note Guaranty of a Significant Subsidiary (or a group of Subsidiaries that would, taken together, be a Significant Subsidiary) ceases to be in full force and effect, other than in accordance the terms of the indenture, or a Guarantor that is a Significant Subsidiary (or a group of Subsidiaries that would, taken together, be a Significant Subsidiary) denies or disaffirms its obligations under its Note Guaranty.

Consequences of an Event of Default

If an Event of Default, other than a bankruptcy default with respect to HII, occurs and is continuing under the indenture, the trustee or the holders of at least 25% in aggregate principal amount of the Notes then outstanding, by written notice to HII (and to the trustee if the notice is given by the holders), may, and the trustee at the request of such holders shall, declare the principal of and accrued and unpaid interest on the Notes to be immediately due and payable. Upon a declaration of acceleration, such principal and interest will become immediately due and payable. If a bankruptcy default occurs with respect to HII, the principal of and accrued and

- 37 -

unpaid interest on such series of Notes then outstanding will become immediately due and payable without any declaration or other act on the part of the trustee or any holder.

In the event of a declaration of acceleration of the Notes solely because an Event of Default described in clause (4) above has occurred and is continuing, the declaration of acceleration of the Notes shall be automatically rescinded and annulled if the event of default or payment default triggering such Event of Default pursuant to clause (4) shall be remedied or cured by HII or a Significant Subsidiary of HII or waived (and the related declaration of acceleration rescinded or annulled) by the holders of the relevant Debt within 20 business days after the declaration of acceleration with respect thereto and if the rescission and annulment of the acceleration of such series of Notes would not conflict with any judgment or decree of a court of competent jurisdiction obtained by the trustee for the payment of amounts due on the Notes.

The holders of a majority in principal amount of the outstanding Notes by written notice to HII and to the trustee may waive all past defaults and rescind and annul a declaration of acceleration and its consequences if

(1) all existing Events of Default, other than the nonpayment of the principal of, premium, if any, and interest on the Notes that have become due solely by the declaration of acceleration, have been cured or waived,

(2) the rescission would not conflict with any judgment or decree of a court of competent jurisdiction, and

(3) all sums paid or advanced by the trustee under the indenture and the reasonable fees, expenses and disbursements of the trustee, its agents and counsel have been paid.

Except as otherwise provided in “—Consequences of an Event of Default” or “—Amendments and Waivers—Amendments with Consent of Holders,” the holders of a majority in principal amount of the outstanding Notes may, by notice to the trustee, waive an existing Default and its consequences. Upon such waiver, the Default will cease to exist, and any Event of Default arising therefrom will be deemed to have been cured, but no such waiver will extend to any subsequent or other Default or impair any right consequent thereon.

The holders of a majority in principal amount of the outstanding Notes may direct the time, method and place of conducting any proceeding for any remedy available to the trustee or exercising any trust or power conferred on the trustee with respect to the Notes. However, the trustee may refuse to follow any direction that conflicts with law or the indenture, that may involve the trustee in personal liability, or that the trustee determines in good faith may be unduly prejudicial to the rights of holders of Notes not joining in the giving of such direction, and may take any other action it deems proper that is not inconsistent with any such direction received from holders of the Notes.

A holder of Notes may not institute any proceeding, judicial or otherwise, with respect to the indenture or the Notes, or for the appointment of a receiver or trustee, or for any other remedy under the indenture or the Notes, unless:

(1) the holder has previously given to the trustee written notice of a continuing Event of Default with respect to the Notes;

(2) holders of at least 25% in aggregate principal amount of outstanding Notes have made written request to the trustee to institute proceedings in respect of the Event of Default in its own name as trustee under the indenture;

(3) holders have offered to the trustee indemnity reasonably satisfactory to the trustee against any costs, liabilities or expenses to be incurred in compliance with such request;

- 38 -

(4) the trustee for 60 days after its receipt of such notice, request and offer of indemnity has failed to institute any such proceeding; and

(5) during such 60-day period, the holders of a majority in aggregate principal amount of the outstanding Notes have not given the trustee a direction that is inconsistent with such written request.

Notwithstanding anything to the contrary, the right of a holder of a Note to receive payment of principal of or interest on its Note on or after the Stated Maturities thereof or after a redemption or repurchase date therefor, or to bring suit for the enforcement of any such payment on or after such dates, may not be impaired or affected without the consent of that holder.

If any Default occurs and is continuing and is known to the trustee, the trustee will send notice of the Default to each holder within 90 days after it occurs, unless the Default has been cured; provided that, except in the case of a default in the payment of the principal of or interest on any Note, the trustee may withhold the notice if and so long as the board of directors, the executive committee or a trust committee of directors of the trustee in good faith determine that withholding the notice is in the interest of the holders.

No Liability of Directors, Officers, Employees, Incorporators, Members and Stockholders

No director, officer, employee, incorporator, manager, member, general or limited partner or stockholder, past, present and future, of HII or any of its Subsidiaries, as such, will have any liability for any obligations of HII or any Guarantor under the Notes, any Note Guaranty or the indenture or for any claim based on, in respect of, or by reason of, such obligations. Each holder of Notes by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes. This waiver may not be effective to waive liabilities under the federal securities laws and it is the view of the SEC that such a waiver is against public policy.

Amendments and Waivers

Amendments without Consent of Holders

HII and the trustee may amend or supplement the indenture or the Notes without notice to or the consent of any noteholder

(1) to cure any ambiguity, defect or inconsistency in the indenture or the Notes;

(3) to comply with any requirements of the SEC in connection with the qualification of the indenture under the Trust Indenture Act;

(6) to provide for any Guarantee of the Notes, to secure the Notes or to confirm and evidence the release, termination or discharge of any Guarantee of or Lien securing the Notes when such release, termination or discharge is permitted by the indenture;

(7) to provide for or confirm the issuance of additional Notes;

- 39 -

Amendments with Consent of Holders

(a) Except as otherwise provided in “—Default and Remedies—Consequences of an Event of Default” or paragraph (b), HII and the trustee may amend the indenture and the Notes with the written consent of the holders of a majority in principal amount of the outstanding Notes and the holders of a majority in principal amount of outstanding Notes may waive future compliance by HII with any provision of the indenture or the Notes.

(b) Notwithstanding the provisions of paragraph (a), without the consent of each holder affected, an amendment or waiver may not

(1) reduce the principal amount of or change the Stated Maturity of any installment of principal of any Note,

(2) reduce the rate of interest or change the Stated Maturity of any interest payment on any Note,

(3) reduce the amount payable upon the redemption of any Note or change the time of any mandatory redemption or, in respect of an optional redemption, the times at which any Note may be redeemed or, once notice of redemption has been given, the time at which it must thereupon be redeemed,

(4) after the time an Offer to Purchase is required to have been made, reduce the purchase amount or purchase price, or extend the latest expiration date or purchase date thereunder,

(5) make any Note payable in money other than that stated in the Note,

(6) impair the right of any holder of Notes to receive any principal payment or interest payment on such holder’s Notes, on or after the Stated Maturity thereof or any redemption or repurchase date therefor, or to institute suit for the enforcement of any such payment,

(7) make any change in the percentage of the principal amount of the Notes required for amendments or waivers,

(8) modify or change any provision of the indenture affecting the ranking of the Notes or any Note Guaranty in a manner adverse to the holders of the Notes, or

(9) make any change in any Note Guaranty that would adversely affect the noteholders in any material respect.

It is not necessary for noteholders to approve the particular form of any proposed amendment, supplement or waiver, but is sufficient if their consent approves the substance thereof.

- 40 -

Defeasance and Discharge

HII may discharge its obligations under either series of Notes and the indenture with respect to such series of Notes by irrevocably depositing in trust with the trustee money sufficient or U.S. Government Obligations the principal of and interest on which will be sufficient, or a combination thereof sufficient, to pay principal of and interest on such series of Notes to maturity or redemption within one year, subject to meeting certain other conditions.

HII may also elect to

(1) discharge most of its obligations in respect of such series of Notes and the indenture, not including obligations related to the defeasance trust or to the replacement, transfer or exchange of such Notes or its obligations to the trustee (“legal defeasance”) or

(2) discharge its obligations under most of the covenants with respect to such series of Notes (and the events listed in clauses (3) (solely with respect to the covenants being defeased), (4) and (6) under “—Default and Remedies—Events of Default” will no longer constitute Events of Default) (“covenant defeasance”)

by irrevocably depositing in trust with the trustee money sufficient or U.S. Government Obligations the principal of and interest on which will be sufficient, or a combination thereof sufficient, to pay principal of and interest on such series of Notes to maturity or redemption and by meeting certain other conditions, including delivery to the trustee of either a ruling received from the Internal Revenue Service or an opinion of counsel to the effect that the holders will not recognize income, gain or loss for federal income tax purposes as a result of the defeasance and will be subject to federal income tax on the same amount and in the same manner and at the same times as would otherwise have been the case. In the case of legal defeasance, such an opinion could not be given absent a change of law after the Issue Date.

In the case of either discharge or defeasance, the related Note Guarantees, if any, will terminate with respect to such series of Notes.

Concerning the Trustee

Wells Fargo Bank, National Association is the trustee under the indenture.

Except during the continuance of an Event of Default, the trustee need perform only those duties that are specifically set forth in the indenture and no others, and no implied covenants or obligations will be read into the indenture against the trustee. In case an Event of Default has occurred and is continuing, the trustee shall exercise those rights and powers vested in it by the indenture, and use the same degree of care and skill in their exercise, as a prudent person would exercise or use under the circumstances in the conduct of his or her own affairs. No provision of the indenture will require the trustee to expend or risk its own funds or otherwise incur any financial liability in the performance of its duties thereunder, or in the exercise of its rights or powers, unless it receives indemnity satisfactory to it against any loss, liability or expense.

The indenture and provisions of the Trust Indenture Act incorporated by reference therein contain limitations on the rights of the trustee, should it become a creditor of any obligor on the Notes, to obtain payment of claims in certain cases, or to realize on certain property received in respect of any such claim as security or otherwise. The trustee is permitted to engage in other transactions with HII and its affiliates; provided that if it acquires any conflicting interest as defined under the Trust Indenture Act, it must either eliminate the conflict within 90 days or resign.

- 41 -

Form, Denomination and Registration of Notes

The Old Notes were, and the New Notes will be, issued in registered form, without interest coupons, in denominations of $2,000 and integral multiples of $1,000 in excess thereof, initially in the form of global notes, as further provided below.

The trustee is not required (i) to issue, register the transfer of or exchange any Note for a period of 15 days before a selection of Notes to be redeemed or purchased pursuant to an Offer to Purchase, (ii) to register the transfer of or exchange any Note so selected for redemption or purchase in whole or in part, except, in the case of a partial redemption or purchase, that portion of the Note not being redeemed or purchased, or (iii) if a redemption or a purchase pursuant to an Offer to Purchase is to occur after a regular record date but on or before the corresponding interest payment date, to register the transfer or exchange of any Note on or after the regular record date and before the date of redemption or purchase. See “—Global Notes,” “—Certificated Notes,” and “Notice to Investors” for a description of additional transfer restrictions applicable to the Notes.

No service charge will be imposed in connection with any transfer or exchange of any Note, but HII may in general require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith.

Global Notes

Global notes evidencing the New Notes will be deposited with the trustee as custodian for DTC and registered in the name of a nominee of DTC. Beneficial interests in the global notes will be shown on records maintained by DTC and its direct and indirect participants. So long as DTC or its nominee is the registered owner or holder of a global note, DTC or such nominee will be considered the sole owner or holder of the Notes represented by such global note for all purposes under the indenture and the Notes. No owner of a beneficial interest in a global note will be able to transfer such interest except in accordance with DTC’s applicable procedures and the applicable procedures of its direct and indirect participants.

Investors may hold their beneficial interests in the global notes directly through DTC if they are participants in DTC, or indirectly through organizations which are participants in DTC.

Payments of principal and interest under each global note will be made to DTC’s nominee as the registered owner of such global note. HII expects that the nominee, upon receipt of any such payment, will immediately credit DTC participants’ accounts with payments proportional to their respective beneficial interests in the principal amount of the relevant global note as shown on the records of DTC. HII also expects that payments by DTC participants to owners of beneficial interests will be governed by standing instructions and customary practices, as is now the case with securities held for the accounts of customers registered in the names of nominees for such customers. Such payments will be the responsibility of such participants, and none of HII, the trustee, the custodian or any paying agent or registrar will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial interests in any global note or for maintaining or reviewing any records relating to such beneficial interests.

If the depositary for a global security is DTC, a Person may hold interests in the global notes through Clearstream Banking S.A. (“Clearstream”), or Euroclear Bank SA/NV, as operator of the Euroclear System (“Euroclear”), in each case, as a participant in DTC. Euroclear and Clearstream will hold interests, in each case, on behalf of their participants through customers’ securities accounts in the names of Euroclear and Clearstream on the books of their respective depositaries, which in turn will hold such interests in customers’ securities in the depositaries’ names on DTC’s books.

Payments, deliveries, transfers, exchanges, notices and other matters relating to the Notes made through Euroclear or Clearstream must comply with the rules and procedures of those systems. Those systems could

- 42 -

change their rules and procedures at any time. HII has no control over those systems or their participants, and HII takes no responsibility for their activities. Transactions between participants in Euroclear or Clearstream, on the one hand, and other participants in DTC, on the other hand, would also be subject to DTC’s rules and procedures.

Investors will be able to make and receive through Euroclear and Clearstream payments, deliveries, transfers, exchanges, notices and other transactions involving any securities held through those systems only on days when those systems are open for business. Those systems may not be open for business on days when banks, brokers and other institutions are open for business in the United States.

In addition, because of time-zone differences, U.S. investors who hold their interests in the Notes through these systems and wish, on a particular day, to transfer their interests, or to receive or make a payment or delivery or exercise any other right with respect to their interests, may find that the transaction will not be effected until the next business day in Luxembourg or Brussels, as applicable. Thus, investors who wish to exercise rights that expire on a particular day may need to act before the expiration date. In addition, investors who hold their interests through both DTC and Euroclear or Clearstream may need to make special arrangements to finance any purchase or sales of their interests between the U.S. and European clearing systems, and those transactions may settle later than transactions within one clearing system.

Certificated Notes

The New Notes will not bear any restricted legend.

A certificated Old Note not exchanged in the exchange offer may be transferred to a Person who wishes to hold a beneficial interest in the U.S. global note only upon receipt by the trustee of a Rule 144A certificate of the transferee. A certificated Old Note may be transferred to a Person who wishes to hold a beneficial interest in the offshore global note only upon receipt by the trustee of a Regulation S certificate of the transferor. A certificated Old Note may be transferred to a Person who wishes to hold a certificated Note only upon receipt by the trustee of (x) a Rule 144A certificate of the transferee, (y) a Regulation S certificate of the transferor or (z) an institutional accredited investor certificate of the transferee, and/or an opinion of counsel and such other certifications and evidence as HII may reasonably require in order to determine that the proposed transfer is being made in compliance with the Securities Act. Any such transfer of certificated Old Notes to an institutional accredited investor must involve Old Notes having a principal amount of not less than $250,000. The restrictions on transfer described in this paragraph will not apply (1) to Notes sold pursuant to a registration statement under the Securities Act or to the New Notes or (2) after such time (if any) as HII determines and instructs the trustee that the Old Notes are eligible for resale pursuant to Rule 144 under the Securities Act without the need for current public information. There is no assurance that the Old Notes will become eligible for resale pursuant to Rule 144. Notwithstanding the foregoing, certificated Notes that do not bear the restricted legend set forth in the section “Notice to Investors” in the offering memorandum pursuant to which the Old Notes were originally issued will not be subject to transfer restrictions.

If DTC notifies HII that it is unwilling or unable to continue as depositary for a global note and a successor depositary is not appointed by HII within 90 days of such notice, or an Event of Default has occurred and the trustee has received a request from DTC, the trustee will exchange each beneficial interest in that global note for one or more certificated Notes registered in the name of the owner of such beneficial interest, as identified by DTC. Any such certificated note issued in exchange for a beneficial interest in the U.S. global note will bear the restricted legend set forth under “Notice to Investors” in the offering memorandum pursuant to which the Old Notes were originally issued and accordingly will be subject to the restrictions on transfer applicable to certificated Old Notes bearing such restricted legend.

- 43 -

Same Day Settlement and Payment

The indenture will require that payments in respect of the Notes represented by the global notes be made by wire transfer of immediately available funds to DTC for transfer to the accounts of its participants. With respect to Notes in certificated form, HII will make all payments by wire transfer of immediately available funds to the accounts specified by the holders thereof or, if no such account is specified, by mailing a check to each holder’s registered address.

The New Notes represented by global notes are expected to be eligible to trade in DTC’s Same-Day Funds Settlement System, and any permitted secondary market trading activity in such Notes will, therefore, be required by DTC to be settled in immediately available funds. HII expects that secondary trading in any certificated Notes will also be settled in immediately available funds.

Governing Law

The indenture, the Old Notes, including any Note Guarantees, and the New Notes and related Note Guarantees shall be governed by, and construed in accordance with, the laws of the State of New York.

Certain Definitions

In the case of any lease which is terminable by the lessee upon payment of a penalty, the Attributable Debt shall be the lesser of:

(1) the Attributable Debt determined assuming termination upon the first date such lease may be terminated (in which case the Attributable Debt shall also include the amount of the penalty, but no rent shall be considered as required to be paid under such lease subsequent to the first date upon which it may be so terminated); and

(2) any “person” or “group” (as such terms are used for purposes of Sections 13(d) and 14(d) of the Exchange Act) is or becomes the “beneficial owner” (as such term is used in Rules 13d-3 under the Exchange Act), directly or indirectly, of more than 50% of the total voting power of the Voting Stock of HII; or

(3) the adoption of a plan relating to the liquidation or dissolution of HII.

Notwithstanding the foregoing, a transaction will not be deemed to involve a Change of Control if (a) HII becomes a direct or indirect wholly owned subsidiary of a holding company (which shall include a parent company) and (b)(i) the holders of the Voting Stock of such holding company immediately following that transaction are substantially the same as the holders of our Voting Stock immediately prior to that transaction or (ii) no “person” (as that term is used in Section 13(d)(3) of the Exchange Act) (other than a holding company satisfying the requirements of this sentence) becomes the “beneficial owner” (as defined in Rules 13d-3 and 13d-5 under the Exchange Act), directly or indirectly, of more than 50% of the voting power of the Voting Stock of such holding company immediately following such transaction.

“Change of Control Triggering Event” means, with respect to either series of Notes, the occurrence of both a Change of Control and a Ratings Decline.

“Comparable Treasury Issue” means the United States Treasury security selected by an Independent Investment Banker as having a maturity comparable to the remaining term of the Notes (assuming, for this purpose, that the Notes matured on the Par Call Date) 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 term of such Notes (assuming, for this purpose, that the Notes matured on the Par Call Date).
