Rhea-AI Filing Summary

SPX Technologies, Inc. is presenting a shelf prospectus that describes its diversified industrial technology businesses serving HVAC and Detection & Measurement markets. The company operates in over 16 countries with more than 4,300 employees and reports 46,758,155 common shares outstanding as of July 25, 2025. Since 2018 SPX has completed 16 acquisitions, deploying approximately $2.1 billion, which the company says has expanded addressable markets and supported topline and earnings growth.

The prospectus registers multiple security types (common stock, preferred stock, debt securities, warrants, purchase contracts and units) for future offerings and explains risks that could affect operations and margins, including tariffs, raw material availability and costs, supply-chain and cybersecurity risks, and certain corporate governance provisions (e.g., classified board until 2027 and supermajority vote requirements) that may affect shareholder influence. The company’s common stock trades on the NYSE under SPXC and the last reported sale price noted in the prospectus was $201.57.

Positive

Shelf registration as a well-known seasoned issuer provides flexibility to raise capital by offering equity, debt or other securities when needed.
Scale and diversification: operations in over 16 countries, > 4,300 employees, and product lines across HVAC and Detection & Measurement.
Proven M&A activity: 16 acquisitions since 2018 with ~$2.1 billion deployed, which the company cites as expanding addressable markets.
No preferred stock outstanding as of July 25, 2025, reducing near-term preferred-share dilution risk.

Negative

Entrenchment provisions: classified board (until 2027), 80% supermajority removal/amendment thresholds and restrictions on written consents may limit shareholder influence.
Regulatory and trade risks: the prospectus specifically cites the impact of tariffs and retaliatory trade measures (including U.S. tariffs announced in 2025) which could raise costs or reduce demand.
Supply-chain and input cost risks: availability and rising costs of raw materials and components could compress margins and are highlighted as material risks.
Debt protections absent: debt securities described generally do not include change-in-control protections unless specified in a prospectus supplement, which could be unfavorable to bondholders.

Insights

TL;DR: Routine S-3 shelf gives SPX capital-raising flexibility; impact depends on if and how management taps the shelf.

SPX’s shelf registration is standard for a well-known seasoned issuer and enables issuance of equity, debt or hybrid securities to fund growth, M&A or refinance indebtedness. The prospectus highlights significant inorganic growth—16 acquisitions since 2018 totaling ~$2.1B—which supports revenue expansion but also implies integration and leverage considerations. Without pricing or offering terms the filing is neutral for valuation; material impact requires specifics on timing, sizes and use of proceeds.

TL;DR: Governance provisions in the charter and by-laws materially limit shareholder actions and could entrench management.

SPX’s certificate and by-laws include significant anti-takeover mechanisms—a classified board (until 2027), an 80% vote requirement to remove directors or amend core charter/by-law provisions, restrictions on action by written consent, and exclusive forum clauses. These provisions may reduce the ability of shareholders to effect change and could influence takeover dynamics and activist strategies. For investors focused on governance, these are noteworthy negatives that can affect control-related outcomes.

TABLE OF CONTENTS

THE COMPANY

Overview

We are a diversified, global supplier of industrial technology equipment serving the heating, ventilation, and cooling (“HVAC”) and detection and measurement markets. With operations in over 16 countries and over 4,300 employees, we offer a wide array of highly engineered industrial technology products with strong brands.

Our strategy is focused on driving organic and inorganic growth in the engineered niches of the HVAC and Detection and Measurement markets. Our organic growth strategy is focused on continued innovation of our technology-enabled products, with leading market positions and strong moats, and leverage of our business system to drive consistent margin execution and sustained growth. We further accelerate growth through a strategic, rigorous, and disciplined approach to acquisitions. Our 16 acquisitions since 2018, totaling approximately $2.1 billion in capital deployed, have significantly increased our addressable markets and further strengthened our competitive position in key end markets. Our value creation framework has resulted in strong topline and earnings growth.

HVAC solutions offered by our businesses include package and process cooling equipment, engineered air movement and handling solutions, hydronic and electrical heating, and ventilation products. Our market leading brands, coupled with our commitment to continuous innovation and focus on our customers’ needs, enables our HVAC cooling and heating businesses to serve an expanding number of industrial, institutional, commercial, data center, and residential customers. Growth for our HVAC businesses will be driven by innovation, increased scalability, and our ability to meet the needs of broader markets.

Our Detection and Measurement product lines encompass underground pipe and cable locators, inspection and rehabilitation equipment, robotic systems, transportation systems, communication technologies, and aids to navigation. Our detection and measurement solutions enable utilities, telecommunication providers and regulators, and municipalities and transit authorities to build, monitor and maintain vital infrastructure. Our technology and decades of experience have afforded us a strong position in specific detection and measurement markets. We intend to expand our portfolio of specialized products through new, innovative hardware and software solutions in an attempt to (i) further capitalize on the detection and measurement markets we currently serve and (ii) expand the number of markets that we serve.

Corporate Information

We are the successor registrant pursuant to Rule 12g-3(a) under the Exchange Act, to SPX Corporation (“Legacy SPX”) as a result of the completion on August 15, 2022 of a holding company reorganization (the “Holding Company Reorganization”) effected as a merger of Legacy SPX with and into SPX Merger, LLC, a subsidiary of the Company. Each share of Legacy SPX’s common stock, par value $0.01 per share, issued and outstanding immediately prior to the consummation of the Holding Company Reorganization was automatically converted into an equivalent corresponding share of the Company’s common stock having the same designations, rights, powers and preferences and the qualifications, limitations and restrictions as the corresponding share of Legacy SPX common stock being converted. Accordingly, upon consummation of the Holding Company Reorganization, Legacy SPX stockholders became stockholders of the Company. Legacy SPX was founded in Muskegon, Michigan in 1912 as the Piston Ring Company and adopted the name SPX Corporation in 1988. Our common stock had been listed on the NYSE since 1972.

Our principal executive offices are located at 6325 Ardrey Kell Road, Suite 400, Charlotte, North Carolina 28277, and our telephone number is (980) 474-3700. Our website is www.spx.com.

RISK FACTORS

Investment in any securities offered pursuant to this prospectus and the applicable prospectus supplement involves risks. Before deciding whether to invest in our securities, you should carefully consider the risk factors incorporated by reference to our most recent Annual Report on Form 10-K and any subsequent Quarterly Reports on Form 10-Q or Current Reports on Form 8-K, and all other information contained or incorporated by reference into this prospectus, as updated by our subsequent filings under the Exchange Act, and the risk factors and other information contained in the applicable prospectus supplement and any applicable free writing prospectus.

If any of these risks actually occurs, our business, financial condition, results of operations or cash flow could be seriously harmed. This could cause the trading price of our securities to decline, resulting in a loss of all or part of your investment. Please also carefully read the sections entitled “Special Note Regarding Forward-Looking Statements” included in this prospectus and “Forward-Looking Information” included in our most recent Annual Report on Form 10-K and any subsequent Quarterly Reports on Form 10-Q or Current Reports on Form 8-K.

See “Where You Can Find More Information; Incorporation by Reference.”

Our authorized capital stock consists of 200,000,000 shares of common stock, par value $0.01 per share, and 3,000,000 shares of preferred stock, without par value, of which 500,000 shares have been designated as Series A Preferred Stock.

The holders of our common stock are entitled to have dividends declared in cash, property, or other securities out of any of our net profits or net assets legally available therefor as and when declared by our board of directors. In the event of the liquidation or dissolution of our business, the holders of common stock will be entitled to receive ratably the balance of net assets available for distribution after payment of any liquidation or distribution preference payable with respect to any then outstanding shares of our preferred stock. Each share of common stock is entitled to one vote with respect to matters brought before the stockholders, except for the election of any directors who may be elected by vote of any outstanding shares of preferred stock voting as a class.

The payment of any dividends on our common stock is subject to the discretion of our board of directors. Any determination to pay any dividends on our common stock is subject to consideration of our financial performance and on-going capital needs, our ability to declare and pay dividends under the terms of our credit agreements and any indentures governing our debt securities, and other factors deemed relevant.

As of July 25, 2025, we had no shares of preferred stock outstanding.

The rights and privileges of our common stock may be subordinate to the rights and preferences of any of our preferred stock.

All shares of any series of preferred stock, as between themselves, are to rank equally and be identical; and all series of preferred stock, as between themselves, are to rank equally and are identical except as set forth in resolutions adopted by our board of directors in authorizing the issuance of a particular series.

Delaware Anti-Takeover Law and Certain Certificate of Incorporation and By-law Provisions

Certain provisions of Delaware law, our Certificate of Incorporation and our By-Laws may have the effect of delaying, deferring or discouraging another person from acquiring control of our Company, including takeover attempts that might result in a premium over the market price for the shares of common stock. These provisions are summarized below.

TABLE OF CONTENTS

Delaware Law

We are subject to the provisions of Section 203 of the Delaware General Corporation Law regulating certain corporate takeover transactions. In general, Section 203 prohibits a publicly held Delaware corporation from engaging in a “business combination” with an “interested stockholder” for a period of three years after the time that the person became an interested stockholder, unless:

•	before the person became an “interested stockholder,” the board of directors of the corporation approved the transaction in which the “interested stockholder” became an “interested stockholder” or approved the business combination;

•

upon consummation of the transaction that resulted in the stockholder becoming an “interested stockholder,” the “interested stockholder” owned at least 85% of the voting stock of the corporation that was outstanding at the time the transaction commenced. For purposes of determining the number of shares outstanding, shares owned by directors who are also officers of the corporation and shares owned by employee stock plans, in specified instances, are excluded; or

•

at or after the time the person became an “interested stockholder,” the business combination is approved by the board of directors of the corporation and authorized at an annual or special meeting of the stockholders by the affirmative vote of at least 66 2/3% of the outstanding voting stock which is not owned by the “interested stockholder.”

A “business combination” is defined generally to include mergers or consolidations between a Delaware corporation and an “interested stockholder,” transactions with an “interested stockholder” involving the assets or stock of the corporation or any majority-owned subsidiary, transactions which increase an “interested stockholder’s” percentage ownership of stock of the corporation or any majority-owned subsidiary, and receipt of various financial benefits from the corporation or any majority-owned subsidiary. In general, an “interested stockholder” is defined as any person or entity that is the beneficial owner of at least 15% of a corporation’s outstanding voting stock or is an affiliate or associate of the corporation and was the beneficial owner of 15% or more of the outstanding voting stock of the corporation at any time within the past three years.

A Delaware corporation may opt out of this provision with an express provision in its original certificate of incorporation or an express provision in its certificate of incorporation or by-laws resulting from a stockholders’ amendment approved by at least a majority of the outstanding voting shares. SPX has not opted out of this provision. The statute could prohibit or delay mergers or other takeover or change-in-control attempts and, accordingly, may discourage attempts to acquire us.

Certificate of Incorporation and By-Law Provisions

Together, our Certificate of Incorporation and By-Laws:

•	provide for a classified board of directors, although the board of directors will cease to be classified commencing with the 2027 annual meeting of stockholders;

•	require that a director may be removed only for cause and only upon the affirmative vote of holders of 80% of the outstanding shares of common stock (together with any other class of our outstanding voting stock voting together as a single class);

•	provide that vacancies on our board of directors, including vacancies resulting from an increase in the size of our board of directors, may be filled only by our board of directors;

•	permit our board of directors to issue, without stockholder approval, preferred stock with such terms as our board of directors may determine;

•	prohibit stockholder action through written consents;

•	require that special meetings of stockholders be called only by our Chairman, President and Chief Executive Officer or our board of directors;

•	include advance-notice requirements for stockholder proposals for a stockholder vote at, and for stockholder nominations for the election of directors at, annual meetings of the stockholders;

combinations involving an “Affiliate” of our Company, any person who beneficially owns, or within the prior two years beneficially owned, directly or indirectly, voting shares of our capital stock having more than 10% of the voting power of our outstanding voting stock, or any assignee of voting shares that had been held by such a beneficial owner (other than a purchaser of such shares in a public offering), unless such business combination transaction satisfies specified price and procedural requirements or is approved by two-thirds of the “Continuing Directors” of our Company (as such terms are defined in our Certificate of Incorporation);

•

permit our board of directors, in determining whether an “acquisition proposal” for our Company is in the best interests of our Company and our stockholders, to consider all factors it deems relevant including, without limitation, social, legal and economic effects upon employees, suppliers, customers and on the communities in which our Company is located, as well as on the long-term business prospects of our Company; and

•

require the affirmative vote of holders of 80% of the outstanding shares of common stock (together with any other class of our outstanding voting stock voting together as a single class) to amend, alter or repeal provisions of the Certificate of Incorporation and the By-Laws prohibiting stockholder action by written consent, the quorum requirements for stockholder meetings, establishing the means for calling special meetings of the stockholders, providing for the number, term, election and removal of directors and the filling of director vacancies, and providing for the supermajority stockholder approval requirement for certain business combination transactions involving substantial stockholders.

These provisions of our Certificate of Incorporation and By-Laws could prohibit or delay mergers or other takeover or change-in-control attempts and, accordingly, may discourage attempts to acquire us.

Exclusive Forum Provisions Applicable to Certain Legal Actions

Our Certificate of Incorporation includes provisions specifying the forum for certain legal actions, as described below.

Delaware Forum Provision

Our Certificate of Incorporation provides that, unless the Company consents in writing to the selection of an alternative forum, the sole and exclusive forum for certain legal actions would be the Court of Chancery of the State of Delaware (the “Delaware Court of Chancery”) or another state or federal court located within the State of Delaware if the Delaware Court of Chancery lacks jurisdiction. The following legal actions are subject to such provision:

•	any derivative action or proceeding brought on behalf of the Company;

•

any action or proceeding asserting a claim of breach of a fiduciary duty owed by any current or former director, officer, other employee or agent, or stockholder of the Company to the Company or the Company’s stockholders, creditors or other constituents, including a claim alleging the aiding and abetting of such a breach of fiduciary duty;

•

any action or proceeding asserting a claim against the Company or any current or former director, officer or other employee or agent of the Company arising pursuant to, or seeking to enforce any right, obligation or remedy under, any provision of the Delaware General Corporation Law (the “DGCL”), or our Certificate of Incorporation or By-Laws, as the foregoing may be amended from time to time;

•	any action or proceeding seeking to interpret, apply, enforce or determine the validity of any provision of our Certificate of Incorporation or By-Laws, as either may be amended from time to time;

•	any action or proceeding asserting a claim governed by the internal affairs doctrine of the State of Delaware;

•	any action asserting an “internal corporate claim” as that term is defined in Section 115 of the DGCL; and

•	any action or proceeding as to which the DGCL confers jurisdiction on the Delaware Court of Chancery.

TABLE OF CONTENTS

Such legal actions include claims that might be brought by stockholders as plaintiffs. Accordingly, this Delaware forum provision of our Certificate of Incorporation limits the ability of a stockholder to bring the specified claims (including a claim against directors, officers or employees) in a judicial forum other than the Delaware Court of Chancery.

Our Certificate of Incorporation provides that anyone who acquires or holds any interest in shares of capital stock of the Company will be deemed to consent to the terms of this Delaware forum provision.

Federal Forum Provision

Our Certificate of Incorporation provides that, unless the Company consents in writing to the selection of an alternative forum, the federal district courts of the United States shall be the exclusive forum for the resolution of any claim arising under the Securities Act. Accordingly, under this federal forum provision claims under the Securities Act could not be brought by a stockholder in a state court. This federal forum provision does not limit stockholders to filing such claims in a federal court located in any particular state. It is not certain whether a state court would enforce this federal forum provision if claims under the Securities Act were brought by a stockholder in a state court.

Our Certificate of Incorporation provides that anyone who acquires or holds any interest in securities of the Company may be deemed to consent to the terms of this federal forum provision.

We may issue debt securities either separately, or together with, or upon the conversion or exercise of or in exchange for, other securities described in this prospectus. Debt securities may be our senior, senior subordinated or subordinated obligations and, unless otherwise specified in a supplement to this prospectus, the debt securities will be our direct, unsecured obligations and may be issued in one or more series.

TABLE OF CONTENTS

Transfer and Exchange

Each debt security will be represented by either one or more global securities registered in the name of The Depository Trust Company (the “Depositary”), or a nominee of the Depositary (we will refer to any debt security represented by a global debt security as a “book-entry debt security”), or a certificate issued in definitive registered form (we will refer to any debt security represented by a certificated security as a “certificated debt security”) as set forth in the applicable prospectus supplement. Except as set forth under the heading “Global Debt Securities and Book-Entry System” below, book-entry debt securities will not be issuable in certificated form.

Certificated Debt Securities. You may transfer or exchange certificated debt securities at any office we maintain for this purpose in accordance with the terms of the indenture. (Section 2.4) No service charge will be made for any transfer or exchange of certificated debt securities, but we may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection with a transfer or exchange. (Section 2.7)

You may effect the transfer of certificated debt securities and the right to receive the principal of, premium and interest on certificated debt securities only by surrendering the certificate representing those certificated debt securities and either reissuance by us or the trustee of the certificate to the new holder or the issuance by us or the trustee of a new certificate to the new holder.

Global Debt Securities and Book-Entry System. Each global debt security representing book-entry debt securities will be deposited with, or on behalf of, the Depositary, and registered in the name of the Depositary or a nominee of the Depositary. Please see “Global Securities.”

Covenants

We will set forth in the applicable prospectus supplement any restrictive covenants applicable to any issue of debt securities.

No Protection in the Event of a Change of Control

Unless we state otherwise in the applicable prospectus supplement, the debt securities will not contain any provisions which may afford holders of the debt securities protection in the event we have a change in control or in the event of a highly leveraged transaction (whether or not such transaction results in a change in control) which could adversely affect holders of debt securities.

Consolidation, Merger and Sale of Assets

We may not consolidate with or merge with or into, or convey, transfer or lease all or substantially all of our properties and assets to any person (a “successor person”) unless:

•	we are the surviving entity or the successor person (if other than SPX) is a corporation, partnership, trust or other entity organized and validly existing under the laws of any U.S. domestic jurisdiction and expressly assumes our obligations on the debt securities and under the indenture; and

•	immediately after giving effect to the transaction, no Default or Event of Default, shall have occurred and be continuing.

Notwithstanding the above, any of our subsidiaries may consolidate with, merge into or transfer all or part of its properties to us. (Section 5.1)

Events of Default

“Event of Default” means with respect to any series of debt securities, any of the following:

•

default in the payment of any interest upon any debt security of that series when it becomes due and payable, and continuance of such default for a period of 30 days (unless the entire amount of the payment is deposited by us with the trustee or with a paying agent prior to the expiration of the 30-day period);

•	default in the payment of principal of any security of that series at its maturity;

•	default in the performance or breach of any other covenant or warranty by us in the indenture (other than a covenant or warranty that has been included in the indenture solely for the benefit of a series of debt

TABLE OF CONTENTS

securities other than that series), which default continues uncured for a period of 60 days after we receive written notice from the trustee or SPX and the trustee receive written notice from the holders of not less than 25% in principal amount of the outstanding debt securities of that series as provided in the indenture;

•	certain voluntary or involuntary events of bankruptcy, insolvency or reorganization of SPX;

•	any other Event of Default provided with respect to debt securities of that series that is described in the applicable prospectus supplement. (Section 6.1)

No Event of Default with respect to a particular series of debt securities (except as to certain events of bankruptcy, insolvency or reorganization) necessarily constitutes an Event of Default with respect to any other series of debt securities. (Section 6.1) The occurrence of certain Events of Default or an acceleration under the indenture may constitute an event of default under certain indebtedness of ours or our subsidiaries outstanding from time to time.

We will provide the trustee written notice of any Default or Event of Default within 30 days of becoming aware of the occurrence of such Default or Event of Default, which notice will describe in reasonable detail the status of such Default or Event of Default and what action we are taking or propose to take in respect thereof. (Section 6.1)

If an Event of Default with respect to debt securities of any series at the time outstanding occurs and is continuing, then the trustee or the holders of not less than 25% in principal amount of the outstanding debt securities of that series may, by a notice in writing to us (and to the trustee if given by the holders), declare to be due and payable immediately the principal of (or, if the debt securities of that series are discount securities, that portion of the principal amount as may be specified in the terms of that series) and accrued and unpaid interest, if any, on all debt securities of that series. In the case of an Event of Default resulting from certain events of bankruptcy, insolvency or reorganization, the principal (or such specified amount) of and accrued and unpaid interest, if any, on all outstanding debt securities will become and be immediately due and payable without any declaration or other act on the part of the trustee or any holder of outstanding debt securities. At any time after a declaration of acceleration with respect to debt securities of any series has been made, but before a judgment or decree for payment of the money due has been obtained by the trustee, the holders of a majority in principal amount of the outstanding debt securities of that series may rescind and annul the acceleration if all Events of Default, other than the non-payment of accelerated principal and interest, if any, with respect to debt securities of that series, have been cured or waived as provided in the indenture. (Section 6.2) We refer you to the prospectus supplement relating to any series of debt securities that are discount securities for the particular provisions relating to acceleration of a portion of the principal amount of such discount securities upon the occurrence of an Event of Default.

The indenture provides that the trustee may refuse to perform any duty or exercise any of its rights or powers under the indenture unless the trustee receives indemnity satisfactory to it against any cost, liability or expense which might be incurred by it in performing such duty or exercising such right or power. (Section 7.1(e)) Subject to certain rights of the trustee, the holders of a majority in principal amount of the outstanding debt securities of any series will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the trustee or exercising any trust or power conferred on the trustee with respect to the debt securities of that series. (Section 6.12)

No holder of any debt security of any series will have any right to institute any proceeding, judicial or otherwise, with respect to the indenture or for the appointment of a receiver or trustee, or for any remedy under the indenture, unless:

•	that holder has previously given to the trustee written notice of a continuing Event of Default with respect to debt securities of that series; and

•

the holders of not less than 25% in principal amount of the outstanding debt securities of that series have made written request, and offered indemnity or security satisfactory to the trustee, to the trustee to institute the proceeding as trustee, and the trustee has not received from the holders of not less than a majority in principal amount of the outstanding debt securities of that series a direction inconsistent with that request and has failed to institute the proceeding within 60 days. (Section 6.7)

Notwithstanding any other provision in the indenture, the holder of any debt security will have an absolute and unconditional right to receive payment of the principal of, premium and any interest on that debt security on or after the due dates expressed in that debt security and to institute suit for the enforcement of payment. (Section 6.8)

TABLE OF CONTENTS

The indenture requires us, within 120 days after the end of our fiscal year, to furnish to the trustee a statement as to compliance with the indenture. (Section 4.3) If a Default or Event of Default occurs and is continuing with respect to the securities of any series and if it is known to a responsible officer of the trustee, the trustee shall mail to each securityholder of the securities of that series notice of a Default or Event of Default within 90 days after it occurs or, if later, after a responsible officer of the trustee has knowledge of such Default or Event of Default. The indenture provides that the trustee may withhold notice to the holders of debt securities of any series of any Default or Event of Default (except in payment on any debt securities of that series) with respect to debt securities of that series if the trustee determines in good faith that withholding notice is in the interest of the holders of those debt securities. (Section 7.5)

Modification and Waiver

We and the trustee may modify, amend or supplement the indenture or the debt securities of any series without the consent of any holder of any debt security:

•	to cure any ambiguity, defect or inconsistency;

•	to comply with covenants in the indenture described above under the heading “Consolidation, Merger and Sale of Assets”;

•	to provide for uncertificated securities in addition to or in place of certificated securities;

•	to add guarantees with respect to debt securities of any series or secure debt securities of any series;

•	to surrender any of our rights or powers under the indenture;

•	to add covenants or events of default for the benefit of the holders of debt securities of any series;

•	to comply with the applicable procedures of the applicable depositary;

•	to make any change that does not adversely affect the rights of any holder of debt securities;

•	to provide for the issuance of and establish the form and terms and conditions of debt securities of any series as permitted by the indenture;

•	to effect the appointment of a successor trustee with respect to the debt securities of any series and to add to or change any of the provisions of the indenture to provide for or facilitate administration by more than one trustee; or

•	to comply with requirements of the SEC in order to effect or maintain the qualification of the indenture under the Trust Indenture Act. (Section 9.1)

We may also modify and amend the indenture with the consent of the holders of at least a majority in principal amount of the outstanding debt securities of each series affected by the modifications or amendments. We may not make any modification or amendment without the consent of the holders of each affected debt security then outstanding if that amendment will:

•	reduce the amount of debt securities whose holders must consent to an amendment, supplement or waiver;

•	reduce the rate of or extend the time for payment of interest (including default interest) on any debt security;

•	reduce the principal of or premium on or change the fixed maturity of any debt security or reduce the amount of, or postpone the date fixed for, the payment of any sinking fund or analogous obligation with respect to any series of debt securities;

•	reduce the principal amount of discount securities payable upon acceleration of maturity;

•

waive a default in the payment of the principal of, premium or interest on any debt security (except a rescission of acceleration of the debt securities of any series by the holders of at least a majority in aggregate principal amount of the then outstanding debt securities of that series and a waiver of the payment default that resulted from such acceleration);

•	make the principal of or premium or interest on any debt security payable in currency other than that stated in the debt security;

TABLE OF CONTENTS

•

make any change to certain provisions of the indenture relating to, among other things, the right of holders of debt securities to receive payment of the principal of, premium and interest on those debt securities and to institute suit for the enforcement of any such payment and to waivers or amendments; or

•	waive a redemption payment with respect to any debt security. (Section 9.3)

Except for certain specified provisions, the holders of at least a majority in principal amount of the outstanding debt securities of any series may on behalf of the holders of all debt securities of that series waive our compliance with provisions of the indenture. (Section 9.2) The holders of a majority in principal amount of the outstanding debt securities of any series may on behalf of the holders of all the debt securities of such series waive any past default under the indenture with respect to that series and its consequences, except a default in the payment of the principal of, premium or any interest on any debt security of that series; provided, however, that the holders of a majority in principal amount of the outstanding debt securities of any series may rescind an acceleration and its consequences, including any related payment default that resulted from the acceleration. (Section 6.13)

Defeasance of Debt Securities and Certain Covenants in Certain Circumstances

Legal Defeasance. The indenture provides that, unless otherwise provided by the terms of the applicable series of debt securities, we may be discharged from any and all obligations in respect of the debt securities of any series (subject to certain exceptions). We will be so discharged upon the irrevocable deposit with the trustee, in trust, of money and/or U.S. government obligations or, in the case of debt securities denominated in a single currency other than U.S. Dollars, government obligations of the government that issued or caused to be issued such currency, that, through the payment of interest and principal in accordance with their terms, will provide money or U.S. government obligations in an amount sufficient in the opinion of a nationally recognized firm of independent public accountants or investment bank to pay and discharge each installment of principal, premium and interest on and any mandatory sinking fund payments in respect of the debt securities of that series on the stated maturity of those payments in accordance with the terms of the indenture and those debt securities.

This discharge may occur only if, among other things, we have delivered to the trustee an opinion of counsel stating that we have received from, or there has been published by, the United States Internal Revenue Service a ruling or, since the date of execution of the indenture, there has been a change in the applicable United States federal income tax law, in either case to the effect that, and based thereon such opinion shall confirm that, the holders of the debt securities of that series will not recognize income, gain or loss for United States federal income tax purposes as a result of the deposit, defeasance and discharge and will be subject to United States federal income tax on the same amounts and in the same manner and at the same times as would have been the case if the deposit, defeasance and discharge had not occurred. (Section 8.3)

Defeasance of Certain Covenants. The indenture provides that, unless otherwise provided by the terms of the applicable series of debt securities, upon compliance with certain conditions:

•	we may omit to comply with the covenant described under the heading “Consolidation, Merger and Sale of Assets” and certain other covenants set forth in the indenture, as well as any additional covenants which may be set forth in the applicable prospectus supplement; and

•	any omission to comply with those covenants will not constitute a Default or an Event of Default with respect to the debt securities of that series (“covenant defeasance”).

The conditions include:

•

depositing with the trustee money and/or U.S. government obligations or, in the case of debt securities denominated in a single currency other than U.S. Dollars, government obligations of the government that issued or caused to be issued such currency, that, through the payment of interest and principal in accordance with their terms, will provide money in an amount sufficient in the opinion of a nationally recognized firm of independent public accountants or investment bank to pay and discharge each installment of principal of, premium and interest on and any mandatory sinking fund payments in respect of the debt securities of that series on the stated maturity of those payments in accordance with the terms of the indenture and those debt securities; and

•

delivering to the trustee an opinion of counsel to the effect that the holders of the debt securities of that series will not recognize income, gain or loss for United States federal income tax purposes as a result of the deposit and related covenant defeasance and will be subject to United States federal income tax on the same amounts and in the same manner and at the same times as would have been the case if the deposit and related covenant defeasance had not occurred. (Section 8.4)

TABLE OF CONTENTS

No Personal Liability of Directors, Officers, Employees or Securityholders

None of our past, present or future directors, officers, employees or securityholders, as such, will have any liability for any of our obligations under the debt securities or the indenture or for any claim based on, or in respect or by reason of, such obligations or their creation. By accepting a debt security, each holder waives and releases all such liability. This waiver and release is part of the consideration for the issue of the debt securities. However, this waiver and release may not be effective to waive liabilities under U.S. federal securities laws, and it is the view of the SEC that such a waiver is against public policy.

Governing Law

The indenture and the debt securities, including any claim or controversy arising out of or relating to the indenture or the securities, will be governed by the laws of the State of New York.

The indenture will provide that we, the trustee and the holders of the debt securities (by their acceptance of the debt securities) irrevocably waive, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to the indenture, the debt securities or the transactions contemplated thereby.

The indenture will provide that any legal suit, action or proceeding arising out of or based upon the indenture or the transactions contemplated thereby may be instituted in the federal courts of the United States of America located in the City of New York or the courts of the State of New York in each case located in the City of New York, and we, the trustee and the holder of the debt securities (by their acceptance of the debt securities) irrevocably submit to the non-exclusive jurisdiction of such courts in any such suit, action or proceeding. The indenture will further provide that service of any process, summons, notice or document by mail (to the extent allowed under any applicable statute or rule of court) to such party’s address set forth in the indenture will be effective service of process for any suit, action or other proceeding brought in any such court. The indenture will further provide that we, the trustee and the holders of the debt securities (by their acceptance of the debt securities) irrevocably and unconditionally waive any objection to the laying of venue of any suit, action or other proceeding in the courts specified above and irrevocably and unconditionally waive and agree not to plead or claim any such suit, action or other proceeding has been brought in an inconvenient forum. (Section 10.10)

DESCRIPTION OF OTHER SECURITIES

We will set forth in the applicable prospectus supplement a description of any warrants, purchase contracts or units issued by us that may be offered and sold pursuant to this prospectus.

TABLE OF CONTENTS

GLOBAL SECURITIES

Book-Entry, Delivery and Form

Unless we indicate differently in any applicable prospectus supplement or free writing prospectus, the securities initially will be issued in book-entry form and represented by one or more global notes or global securities, or, collectively, global securities. The global securities will be deposited with, or on behalf of, The Depository Trust Company, New York, New York, as depositary (“DTC”), and registered in the name of Cede & Co., the nominee of DTC. Unless and until it is exchanged for individual certificates evidencing securities under the limited circumstances described below, a global security may not be transferred except as a whole by the depositary to its nominee or by the nominee to the depositary, or by the depositary or its nominee to a successor depositary or to a nominee of the successor depositary.

DTC has advised us that it is:

•	a limited-purpose trust company organized under the New York Banking Law;

•	a “banking organization” within the meaning of the New York Banking Law;

•	a member of the Federal Reserve System;

•	a “clearing corporation” within the meaning of the New York Uniform Commercial Code; and

•	a “clearing agency” registered pursuant to the provisions of Section 17A of the Exchange Act.

DTC holds securities that its participants deposit with DTC. DTC also facilitates the settlement among its participants of securities transactions, such as transfers and pledges, in deposited securities through electronic computerized book-entry changes in participants’ accounts, thereby eliminating the need for physical movement of securities certificates. “Direct participants” in DTC include securities brokers and dealers, including underwriters, banks, trust companies, clearing corporations and other organizations. DTC is a wholly-owned subsidiary of The Depository Trust & Clearing Corporation (“DTCC”). DTCC is the holding company for DTC, National Securities Clearing Corporation and Fixed Income Clearing Corporation, all of which are registered clearing agencies. DTCC is owned by the users of its regulated subsidiaries. Access to the DTC system is also available to others, which we sometimes refer to as indirect participants, that clear through or maintain a custodial relationship with a direct participant, either directly or indirectly. The rules applicable to DTC and its participants are on file with the SEC.

Purchases of securities under the DTC system must be made by or through direct participants, which will receive a credit for the securities on DTC’s records. The ownership interest of the actual purchaser of a security, which we sometimes refer to as a beneficial owner, is in turn recorded on the direct and indirect participants’ records. Beneficial owners of securities will not receive written confirmation from DTC of their purchases. However, beneficial owners are expected to receive written confirmations providing details of their transactions, as well as periodic statements of their holdings, from the direct or indirect participants through which they purchased securities. Transfers of ownership interests in global securities are to be accomplished by entries made on the books of participants acting on behalf of beneficial owners. Beneficial owners will not receive certificates representing their ownership interests in the global securities, except under the limited circumstances described below.

To facilitate subsequent transfers, all global securities deposited by direct participants with DTC will be registered in the name of DTC’s partnership nominee, Cede & Co., or such other name as may be requested by an authorized representative of DTC. The deposit of securities with DTC and their registration in the name of Cede & Co. or such other nominee will not change the beneficial ownership of the securities. DTC has no knowledge of the actual beneficial owners of the securities. DTC’s records reflect only the identity of the direct participants to whose accounts the securities are credited, which may or may not be the beneficial owners. The participants are responsible for keeping account of their holdings on behalf of their customers.

So long as the securities are in book-entry form, you will receive payments and may transfer securities only through the facilities of the depositary and its direct and indirect participants. We will maintain an office or agency in the location specified in the prospectus supplement for the applicable securities, where notices and demands in respect of the securities and the indenture may be delivered to us and where certificated securities may be surrendered for payment, registration of transfer or exchange.

TABLE OF CONTENTS

Conveyance of notices and other communications by DTC to direct participants, by direct participants to indirect participants and by direct participants and indirect participants to beneficial owners will be governed by arrangements among them, subject to any legal requirements in effect from time to time.

Redemption notices will be sent to DTC. If less than all of the securities of a particular series are being redeemed, DTC’s practice is to determine by lot the amount of the interest of each direct participant in the securities of such series to be redeemed.

Neither DTC nor Cede & Co. (or such other DTC nominee) will consent or vote with respect to the securities. Under its usual procedures, DTC will mail an omnibus proxy to us as soon as possible after the record date. The omnibus proxy assigns the consenting or voting rights of Cede & Co. to those direct participants to whose accounts the securities of such series are credited on the record date, identified in a listing attached to the omnibus proxy.

So long as securities are in book-entry form, we will make payments on those securities to the depositary or its nominee, as the registered owner of such securities, by wire transfer of immediately available funds. If securities are issued in definitive certificated form under the limited circumstances described below and unless if otherwise provided in the description of the applicable securities herein or in the applicable prospectus supplement, we will have the option of making payments by check mailed to the addresses of the persons entitled to payment or by wire transfer to bank accounts in the United States designated in writing to the applicable trustee or other designated party at least 15 days before the applicable payment date by the persons entitled to payment, unless a shorter period is satisfactory to the applicable trustee or other designated party.

Redemption proceeds, distributions and dividend payments on the securities will be made to Cede & Co., or such other nominee as may be requested by an authorized representative of DTC. DTC’s practice is to credit direct participants’ accounts upon DTC’s receipt of funds and corresponding detail information from us on the payment date in accordance with their respective holdings shown on DTC records. Payments by participants to beneficial owners will be governed by standing instructions and customary practices, as is the case with securities held for the account of customers in bearer form or registered in “street name.” Those payments will be the responsibility of participants and not of DTC or us, subject to any statutory or regulatory requirements in effect from time to time. Payment of redemption proceeds, distributions and dividend payments to Cede & Co., or such other nominee as may be requested by an authorized representative of DTC, is our responsibility, disbursement of payments to direct participants is the responsibility of DTC, and disbursement of payments to the beneficial owners is the responsibility of direct and indirect participants.

Except under the limited circumstances described below, purchasers of securities will not be entitled to have securities registered in their names and will not receive physical delivery of securities. Accordingly, each beneficial owner must rely on the procedures of DTC and its participants to exercise any rights under the securities and the indenture.

The laws of some jurisdictions may require that some purchasers of securities take physical delivery of securities in definitive form. Those laws may impair the ability to transfer or pledge beneficial interests in securities.

DTC may discontinue providing its services as securities depositary with respect to the securities at any time by giving reasonable notice to us. Under such circumstances, in the event that a successor depositary is not obtained, securities certificates are required to be printed and delivered.

As noted above, beneficial owners of a particular series of securities generally will not receive certificates representing their ownership interests in those securities. However, if:

•

DTC notifies us that it is unwilling or unable to continue as a depositary for the global security or securities representing such series of securities or if DTC ceases to be a clearing agency registered under the Exchange Act at a time when it is required to be registered and a successor depositary is not appointed within 90 days of the notification to us or of our becoming aware of DTC’s ceasing to be so registered, as the case may be;

•	we determine, in our sole discretion, not to have such securities represented by one or more global securities; or

•	an Event of Default has occurred and is continuing with respect to such series of securities,

we will prepare and deliver certificates for such securities in exchange for beneficial interests in the global securities. Any beneficial interest in a global security that is exchangeable under the circumstances described in the preceding sentence will be exchangeable for securities in definitive certificated form registered in the names that the depositary directs. It is expected that these directions will be based upon directions received by the depositary from its participants with respect to ownership of beneficial interests in the global securities.

TABLE OF CONTENTS

Euroclear and Clearstream

If so provided in the applicable prospectus supplement, you may hold interests in a global security through Clearstream Banking S.A., which we refer to as “Clearstream,” or Euroclear Bank S.A./N.V., as operator of the Euroclear System, which we refer to as “Euroclear,” either directly if you are a participant in Clearstream or Euroclear or indirectly through organizations which are participants in Clearstream or Euroclear. Clearstream and Euroclear will hold interests on behalf of their respective participants through customers’ securities accounts in the names of Clearstream and Euroclear, respectively, on the books of their respective U.S. depositaries, which in turn will hold such interests in customers’ securities accounts in such depositaries’ names on DTC’s books.

Clearstream and Euroclear are securities clearance systems in Europe. Clearstream and Euroclear hold securities for their respective participating organizations and facilitate the clearance and settlement of securities transactions between those participants through electronic book-entry changes in their accounts, thereby eliminating the need for physical movement of certificates.

Payments, deliveries, transfers, exchanges, notices and other matters relating to beneficial interests in global securities owned through Euroclear or Clearstream must comply with the rules and procedures of those systems. Transactions between participants in Euroclear or Clearstream, on one hand, and other participants in DTC, on the other hand, are also subject to DTC’s rules and procedures.

Investors will be able to make and receive through Euroclear and Clearstream payments, deliveries, transfers and other transactions involving any beneficial interests in global 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.

Cross-market transfers between participants in DTC, on the one hand, and participants in Euroclear or Clearstream, on the other hand, will be effected through DTC in accordance with the DTC’s rules on behalf of Euroclear or Clearstream, as the case may be, by their respective U.S. depositaries; however, such cross-market transactions will require delivery of instructions to Euroclear or Clearstream, as the case may be, by the counterparty in such system in accordance with the rules and procedures and within the established deadlines (European time) of such system. Euroclear or Clearstream, as the case may be, will, if the transaction meets its settlement requirements, deliver instructions to its U.S. depositary to take action to effect final settlement on its behalf by delivering or receiving interests in the global securities through DTC, and making or receiving payment in accordance with normal procedures for same-day fund settlement. Participants in Euroclear or Clearstream may not deliver instructions directly to their respective U.S. depositaries.

Due to time zone differences, the securities accounts of a participant in Euroclear or Clearstream purchasing an interest in a global security from a direct participant in DTC will be credited, and any such crediting will be reported to the relevant participant in Euroclear or Clearstream, during the securities settlement processing day (which must be a business day for Euroclear or Clearstream) immediately following the settlement date of DTC. Cash received in Euroclear or Clearstream as a result of sales of interests in a global security by or through a participant in Euroclear or Clearstream to a direct participant in DTC will be received with value on the settlement date of DTC but will be available in the relevant Euroclear or Clearstream cash account only as of the business day for Euroclear or Clearstream following DTC’s settlement date.

You are urged to contact DTC, Clearstream and Euroclear or their respective participants directly to discuss those matters.

Neither we nor any agent of ours will have any responsibility for the performance or nonperformance by DTC, Clearstream and Euroclear or their respective participants of these or any other rules or procedures governing their respective operations.

Indemnification of Directors and Officers

Subsection (a) of Section 145 of the General Corporation Law of the State of Delaware, or the DGCL, empowers a corporation to indemnify any person who was or is a party or who is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation) by reason of the fact that the person is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by the person in connection with such action, suit or proceeding if the person acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe the person’s conduct was unlawful.

Subsection (b) of Section 145 empowers a corporation to indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the corporation to procure a judgment in its favor by reason of the fact that the person acted in any of the capacities set forth above, against expenses (including attorneys’ fees) actually and reasonably incurred by the person in connection with the defense or settlement of such action or suit if the person acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of the corporation, except that no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to the corporation unless and only to the extent that the Court of Chancery or the court in which such action or suit was brought shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the Court of Chancery or such other court shall deem proper.

Section 145 further provides that to the extent a director or officer of a corporation has been successful on the merits or otherwise in the defense of any action, suit or proceeding referred to in subsections (a) and (b) of Section 145, or in defense of any claim, issue or matter therein, such person shall be indemnified against expenses (including attorneys’ fees) actually and reasonably incurred by such person in connection therewith; that indemnification provided for by Section 145 shall not be deemed exclusive of any other rights to which the indemnified party may be entitled; and the indemnification provided for by Section 145 shall, unless otherwise provided when authorized or ratified, continue as to a person who has ceased to be a director, officer, employee or

TABLE OF CONTENTS

agent and shall inure to the benefit of such person’s heirs, executors and administrators. Section 145 also empowers the corporation to purchase and maintain insurance on behalf of any person who is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against any liability asserted against such person and incurred by such person in any such capacity, or arising out of his status as such, whether or not the corporation would have the power to indemnify such person against such liabilities under Section 145.

Section 102(b)(7) of the DGCL provides that a corporation’s certificate of incorporation may contain a provision eliminating or limiting the personal liability of a director to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director, provided that such provision shall not eliminate or limit the liability of a director (i) for any breach of the director’s duty of loyalty to the corporation or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) under Section 174 of the DGCL, or (iv) for any transaction from which the director derived an improper personal benefit.

Our Certificate of Incorporation provides that we will indemnify each person who was or is made a party or is threatened to be made a party to or is involved in any action, suit or proceeding, whether civil, criminal, administrative or investigative (hereinafter a “proceeding”), by reason of the fact that he or she or a person of whom he or she is the legal representative is or was a director or officer or is or was serving at our request as a director, officer or employee or agent of another corporation or of a partnership, joint venture, trust or other enterprise, including service with respect to employee benefit plans, whether the basis of such proceeding is alleged action in an official capacity as a director, officer, employee or agent or in any other capacity while serving as a director, officer, employee or agent, against all expenses, liability and loss (including attorneys’ fees, judgments, fines, ERISA excise taxes or penalties and amounts paid or to be paid in settlement) reasonably incurred or suffered by such person in connection therewith, except for liability (i) for any breach of the director’s duty of loyalty to us or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) under Section 174 of the DGCL, or (iv) for any transaction from which the director derived an improper personal benefit. No indemnification shall be made with respect to proceedings seeking to enforce rights to indemnification unless such proceeding (or part thereof) was authorized by the board of directors. The right to indemnification conferred above shall be a contract right and shall include the right to be paid the expenses incurred in defending any such proceeding in advance of its final disposition. Expenses must be advanced to an indemnitee under certain circumstances.

Any underwriting agreement or distribution agreement that the registrant enters into with any underwriters or agents involved in the offering or sale of any securities registered hereby may require such underwriters or dealers to indemnify the registrant, some or all of its directors and officers and its controlling persons, if any, for specified liabilities, which may include liabilities under the Securities Act.

II-3

TABLE OF CONTENTS

(iii)

To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

provided, however, that paragraphs (a)(1)(i), (a)(1)(ii), and (a)(1)(iii) above do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the registrant pursuant to section 13 or section 15(d) of the Exchange Act that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is a part of the registration statement.

(2)

That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3)	To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(5)	That, for the purpose of determining liability under the Securities Act to any purchaser:

(A)	Each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

(B)

Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x) for the purpose of providing the information required by section 10(a) of the Securities Act shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.

(6)	That, for the purpose of determining liability of the registrant under the Securities Act to any purchaser in the initial distribution of the securities:

The undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

(i)	Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

(c)-(g)

[Reserved]

(h)

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

(j)

The undersigned registrant hereby undertakes to file an application for the purpose of determining the eligibility of the trustee to act under subsection (a) of Section 310 of the Trust Indenture Act (the “Act”) in accordance with the rules and regulations prescribed by the SEC under section 305(b)(2) of the Act.
