This prospectus provides you with a general description of the securities we or any selling securityholders may offer. You should assume that the information appearing in this prospectus is accurate only as of the date of this prospectus. This prospectus may be supplemented from time to time by one or more prospectus supplements. If there is any inconsistency between the information in this prospectus and any prospectus supplement, you should rely on the information contained in the prospectus supplement. Wherever references are made in this prospectus to information that will be included in a prospectus supplement, to the extent permitted by applicable law, rules, or regulations, we may instead include such information or add, update, or change the information contained in this prospectus by means of a post-effective amendment to the registration statement of which this prospectus is a part, through filings we make with the SEC that are incorporated by reference in this prospectus, or by any other method as may then be permitted under applicable law, rules, or regulations.

RISK FACTORS

An investment in our securities involves risks. Before deciding to purchase any of our securities, you should carefully consider the risks described in the documents incorporated by reference in this prospectus and, if applicable, in any prospectus supplement used in connection with an offering of securities, before making an investment decision, including those risks identified under “Part I—Item IA. Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2018, which is incorporated by reference in this prospectus and which may be amended, supplemented or superseded from time to time by other reports that we subsequently file with the SEC. The risks that we discuss in the documents incorporated by reference in this prospectus are those we currently believe may materially affect our company.

This prospectus and the documents incorporated by reference herein contain certain forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). The accompanying prospectus supplement and any applicable free writing prospectus may also contain these type of forward-looking statements.

Such forward-looking statements are subject to various risks and uncertainties and the Company claims the protection afforded by the safe harbor for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995. Actual results could differ materially from those currently anticipated due to a number of factors in addition to those discussed elsewhere herein, including in the “Risk Factors” section in this prospectus, and in the Company’s other public filings, press releases, and discussions with Company management, including:

The public can obtain any documents that we file or furnish with the SEC at www.sec.gov. The Company’s Annual Report on Form 10-K, Quarterly Reports on Form 10-Q, Current Reports on Form 8-K, and all amendments to those reports are made available free of charge through the Investor Relations section of the Company’s website at www.labcorp.com as soon as reasonably practicable after such material is electronically filed with, or furnished to, the SEC. The information contained on our website (other than the SEC filings expressly referred to below) is not incorporated by reference herein and does not form a part of this prospectus.

You may review a copy of the registration statement and all of its exhibits through the SEC’s website.

INCORPORATION OF CERTAIN INFORMATION BY REFERENCE

The SEC allows us to “incorporate by reference” in this prospectus certain information we file with the SEC, which means that we may disclose important information in this prospectus by referring you to the document that contains the information. The information incorporated by reference is deemed to be a part of this prospectus, except for any information superseded by information in this prospectus. The information incorporated by reference is an important part of this prospectus, and information we file later with the SEC will automatically update and supersede this information.

We also incorporate by reference any future filings we make with the SEC under Sections 13(a), 13(c), 14 or 15(d) of the Exchange Act until the offering of the securities covered by this prospectus is completed or the offering is otherwise terminated; provided, however, that we are not incorporating by reference any documents or information, including parts of documents that we file with the SEC, that are deemed to be furnished and not filed with the SEC. Unless specifically stated to the contrary, none of the information we disclose under Items 2.02 or 7.01 of any Current Report on Form 8-K that we may from time to time furnish to the SEC will be incorporated by reference into, or otherwise included in, this prospectus.

USE OF PROCEEDS

Unless we specify otherwise in a prospectus supplement, we intend to use the net proceeds from sales of securities by us to provide additional funds for general corporate purposes. These purposes may include the repayment of indebtedness, future acquisitions, capital expenditures, working capital, and any other corporate purpose. If net proceeds from a specific offering are intended to be used for the repayment of indebtedness, the applicable prospectus supplement will describe the relevant terms of the debt to be repaid. We will not receive proceeds from sales of securities by persons other than us except as may otherwise be stated in an applicable prospectus supplement.

DESCRIPTION OF DEBT SECURITIES

This prospectus may be used for an offering of any combination of our senior debt securities or subordinated debt securities. Senior debt securities will be issued under the indenture dated as of November 19, 2010 between us and U.S. Bank National Association, as the trustee. The indenture has been qualified under the Trust Indenture Act of 1939. The indenture has been incorporated by reference as an exhibit to the registration statement.

Subordinated debt securities will be issued under a separate indenture between us, as issuer, and the trustee identified in the prospectus supplement. Further information regarding the trustee for subordinated debt securities will be provided in the prospectus supplement. The form of indenture is filed as an exhibit to the registration statement of which this prospectus is a part and is available as described above under the heading “Where To Find Additional Information.” Any indenture for subordinated debt securities will be subject to and governed by the Trust Indenture Act of 1939.

Particular debt securities will be issued in one or more series that will be established by board resolution, officers’ certificate or supplemental indenture. Where we refer to either indenture below, we mean the indenture as well as any applicable board resolution, officers’ certificate or supplemental indenture.

The prospectus supplement will describe the particular terms of any debt securities that may be offered and may supplement the terms summarized below. The following summaries of the debt securities and the indentures are not complete. We urge you to read the indentures filed as exhibits to the registration statement that includes this prospectus and the description of the additional terms of the debt securities included in the applicable prospectus supplement.

7

General

We may issue an unlimited principal amount of debt securities in separate series. We may specify a maximum aggregate principal amount for the debt securities of any series. The debt securities will have terms that are consistent with the indentures. Senior debt securities will rank equal in right of payment with all our other unsecured and unsubordinated debt. Subordinated debt securities will be paid only if all payments due under our senior indebtedness, including any outstanding senior debt securities, have been made.

Because we are a holding company whose operations are mostly conducted through operating subsidiaries, the debt securities will be structurally subordinated to any and all existing and future indebtedness, whether or not secured, and other liabilities and claims of holders of preferred stock, of any of our subsidiaries. The indentures under which the debt securities will be issued do not restrict our subsidiaries from issuing additional indebtedness or preferred stock that would be structurally senior in right of payment to the subordinated debt securities, although certain limitations may be imposed under the terms of any such debt securities, which limitations will be set forth in a prospectus supplement.

The indentures do not limit the amount of other debt that we may incur or whether that debt is senior to the debt securities offered by this prospectus. Other than the restrictions on liens, sale and leaseback transactions and indebtedness and preferred stock issued by our subsidiaries that may be applicable to senior debt securities or any other restrictions described in any prospectus supplement, the indentures do not contain financial or similar restrictive covenants. The indentures do not contain any provision to protect holders of debt securities against a sudden or dramatic decline in our ability to pay our debt.

The prospectus supplement will describe the debt securities being offered and the price or prices at which debt securities will be offered. The description will include:

8

We may sell the debt securities at a substantial discount below their stated principal amount. We will describe U.S. federal income tax considerations, if any, applicable to debt securities sold at an original issue discount in the prospectus supplement. An “original issue discount security” is any debt security sold for less than its face value, and that provides that the holder cannot receive the full face value if the maturity of the security is accelerated. The prospectus supplement relating to any original issue discount securities will describe the particular provisions relating to acceleration of the maturity upon the occurrence of an event of default. In addition, we will describe U.S. federal income tax or other considerations applicable to any debt securities that are denominated in a currency or unit other than U.S. dollars in the prospectus supplement.

Conversion and Exchange Rights

The prospectus supplement will describe, if applicable, the terms on which you may convert debt securities into or exchange them for debt securities, preferred stock, common stock or other securities. The conversion or exchange may be mandatory or may be at your option. The prospectus supplement will describe how the amount of debt securities, number of shares of preferred stock or common stock, or the amount of other securities to be received upon conversion or exchange would be calculated.

Optional Redemption

The prospectus supplement will set forth whether we will have the right to redeem a series of debt securities before maturity. Unless the prospectus supplement provides otherwise, we will mail a notice of redemption to holders at least 30, but not more than 60 days, prior to the date of redemption. If we have the right to redeem less than all of a series of debt securities, the trustee shall select pro rata, by lot or in such other manner as it deems appropriate, the debt securities to be redeemed. If any debt securities of a series are to be redeemed only in part, the notice of redemption will state the portion of the principal amount of the debt security to be redeemed. Upon cancellation of a debt security surrendered for redemption in part, we will issue a new debt security in principal amount in multiples of $1,000 equal to the unredeemed portion of the surrendered note in the name of the holder thereof. Debt securities called for redemption will become due on the date fixed for redemption. On and after the redemption date, interest will cease to accrue on debt securities or portions of the debt securities called for redemption.

9

Make-Whole Redemption

The prospectus supplement will set forth whether we will have the right to redeem a series of debt securities in whole or in part at a price based on a Make-Whole Amount. Unless the prospectus supplement provides otherwise, the following terms shall apply to our right to redeem a series of debt securities based on a Make-Whole Amount. We may redeem all or part of the debt securities of the affected series at any time at our option at a redemption price equal to the greater of:

For purposes of a redemption at a price based on a Make-Whole Amount:

“Make-Whole Amount” means the sum, as determined by the Quotation Agent, of the present values of the scheduled payments of principal and interest (exclusive of interest to the redemption date) from the redemption date to the maturity date of the debt securities being redeemed, in each case discounted to the redemption date on a semi-annual basis, assuming a 360-day year consisting of twelve 30-day months, at the Adjusted Treasury Rate, plus accrued and unpaid interest on the principal amount of the debt securities being redeemed to the redemption date.

“Adjusted Treasury Rate” means, with respect to any redemption date, (1) the yield, under the heading that represents the average for the immediately preceding week, appearing in the most recently published statistical release designated “H.15(519)” or any successor publication that is published weekly by the Board of Governors of the Federal Reserve System and that establishes yields on actively traded United States Treasury securities adjusted to constant maturity under the caption “Treasury Constant Maturities,” for the maturity corresponding to the Comparable Treasury Issue (if no maturity is within three months before or after the remaining term of the securities of the series being redeemed, yields for the two published maturities most closely corresponding to the Comparable Treasury Issue shall be determined and the Adjusted Treasury Rate shall be interpolated or extrapolated from such yields on a straight line basis, rounding to the nearest month), or (2) if such release (or any successor release) is not published during the week preceding the calculation date or does not contain such yields, the rate per year equal to the semi-annual equivalent yield to maturity of the Comparable Treasury Issue (expressed as a percentage of its principal amount) assuming a price for the Comparable Treasury Issue equal to the Comparable Treasury Price for such redemption date, in each case calculated on the third business day preceding the redemption date, plus the spread (the “Make-Whole Spread”) specified in a prospectus supplement relating to the affected series of debt securities.

“Comparable Treasury Issue” means the United States Treasury security selected by the Quotation Agent as having a maturity comparable to the remaining term from the redemption date to the maturity date of the debt securities being 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 the debt securities of a series.

“Comparable Treasury Price” means, with respect to any redemption date, if clause (2) of the Adjusted Treasury Rate is applicable, the average of three, or such lesser number as is obtained by the trustee, Reference Treasury Dealer Quotations for such redemption date.

“Quotation Agent” means a Reference Treasury Dealer selected by us.

“Reference Treasury Dealer” means Citigroup Global Markets Inc. and it successors and assigns, and two other nationally recognized investment banking firms selected by us that are primary U.S. government securities dealers.

10

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any redemption date, the average, as determined by the trustee, of the bid and asked prices for the Comparable Treasury Issue, expressed in each case as a percentage of its principal amount, quoted in writing to the trustee by such Reference Treasury Dealer at 5:00 p.m., New York City time, on the third business day preceding such redemption date.

Subordination of Subordinated Debt Securities

The indebtedness underlying any subordinated debt securities will be payable only if all payments due under our senior indebtedness, including any outstanding senior debt securities, have been made. Senior indebtedness includes the principal, premium (if any) and unpaid interest on all present and future:

in each case unless the instrument creating or evidencing the indebtedness or obligation or pursuant to which the same is outstanding provides that (x) such indebtedness or obligation is not senior in right of payment to the subordinated debt securities, or (y) such indebtedness or obligation is subordinated to any other obligation, unless such indebtedness or obligation expressly provides that such indebtedness or obligations be senior in right of payment to the subordinated debt securities.

If we distribute our assets to creditors upon any dissolution, winding-up, liquidation or reorganization or in bankruptcy, insolvency, receivership, or similar proceedings, we must first pay all amounts due or to become due on all senior indebtedness before we pay the principal of, or any premium or interest on, the subordinated debt securities. In the event the subordinated debt securities are accelerated because of an event of default, we may not make any payment on the subordinated debt securities until we have paid all senior indebtedness or the acceleration is rescinded. If the payment of subordinated debt securities accelerates because of an event of default, we must promptly notify holders of senior indebtedness of the acceleration.

If we experience a bankruptcy, dissolution or reorganization, holders of senior indebtedness may receive more, ratably, and holders of subordinated debt securities may receive less, ratably, than our other creditors. The indenture for subordinated debt securities will not limit our ability to incur additional senior indebtedness.

11

Form, Exchange and Transfer

Unless the prospectus supplement indicates otherwise, we will issue debt securities only in fully registered form, without coupons, and only in denominations of $1,000 and integral multiples thereof. The holder of a debt security may elect, subject to the terms of the indentures and the limitations applicable to global securities, to exchange them for other debt securities of the same series of any authorized denomination and of similar terms and aggregate principal amount.

Holders of debt securities may present them for exchange as provided above or for registration of transfer, duly endorsed or with the form of transfer duly executed, at the office of the transfer agent we designate for that purpose. We will not impose a service charge for any registration of transfer or exchange of debt securities, but we may require a payment sufficient to cover any tax or other governmental charge payable in connection with the transfer or exchange. Unless the prospectus supplement indicates otherwise, the corporate trust office of the trustee will be the transfer agent for the debt securities. We may designate additional transfer agents or rescind the designation of any transfer agent or approve a change in the office through which any transfer agent acts, but we must maintain a transfer agent in each place where we will make payment on debt securities.

Global Securities

The debt securities of a series may be represented by one or more global securities that will have an aggregate principal amount equal to that of all debt securities of that series, meaning that beneficial owners of the debt securities will not receive certificates representing their ownership interests in the debt securities, except in the event the book-entry system for the debt securities of that series is discontinued. Each global security will be registered in the name of a depository identified in the prospectus supplement. We will deposit the global security with the depository or a custodian, and the global security will bear a legend regarding the restrictions on exchanges and registration of transfer.

The Depository Trust Company is expected to serve as depository. Unless and until it is exchanged in whole or in part for the individual debt securities represented thereby, a global security may not be transferred except as a whole by the depository for the global security to a nominee of such depository or by a nominee of such depository to such depository or another nominee of such depository or by the depository or any nominee of such depository to a successor depository or a nominee of such successor. The specific terms of the depository arrangement with respect to a series of debt securities that differ from the terms described here will be described in the applicable prospectus supplement.

Unless otherwise indicated in the applicable prospectus supplement, we anticipate that the following provisions will apply to depository arrangements.

Upon the issuance of a global security, the depository for the global security or its nominee will credit on its book-entry registration and transfer system the respective amounts of the individual debt securities represented by such global security to the accounts of persons that have accounts with such depository, who are called “participants.” Such accounts shall be designated by the underwriters, dealers, or agents with respect to the debt securities or by us if the securities are offered and sold directly by us. Ownership of beneficial interests in a global security will be limited to the depository’s participants or persons that may hold interests through such participants. Ownership of beneficial interests in the global security will be shown on, and the transfer of that ownership will be effected only through, records maintained by the applicable depository or its nominee (with respect to beneficial interests of participants) and records of the participants (with respect to beneficial interests of persons who hold through participants). The laws of some states require that certain purchasers of securities take physical delivery of such securities in definitive form. Such limits and laws may impair the ability to own, pledge, or transfer beneficial interest in a global security.

So long as the depository for a global security or its nominee is the registered owner of such global security, such depository or nominee, as the case may be, will be considered the sole owner or holder of the securities

12

represented by such global security for all purposes under the applicable indenture. Except as provided below or in the prospectus supplement, owners of beneficial interest in a global security will not be entitled to have any of the individual debt securities of the series represented by such global security registered in their names, will not receive or be entitled to receive physical delivery of any such debt securities in definitive form and will not be considered the owners or holders thereof under the applicable indenture.

Payments of amounts payable with respect to individual debt securities represented by a global security registered in the name of a depository or its nominee will be made to the depository or its nominee, as the case may be, as the registered owner of the global security representing such debt securities. None of us, our officers, board members, or any trustee, paying agent, or security registrar for an individual series of debt securities will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests in the global security for such securities or for maintaining, supervising, or reviewing any records relating to such beneficial ownership interests.

We expect that the depository for a series of debt securities offered by means of this prospectus or its nominee, upon receipt of any payment of principal, premium, interest, or other amount in respect of a permanent global security representing any of such debt securities, will immediately credit its participants’ accounts with payments in amounts proportionate to their respective beneficial interests in the principal amount of such global security as shown on the records of such depository or its nominee. We also expect that payments by participants to owners of beneficial interests in such global security held through such participants will be governed by standing instructions and customary practices, as is the case with securities held for the account of customers registered in “street name.” Such payments will be the responsibility of such participants.

If a depository for a series of debt securities is at any time unwilling, unable, or ineligible to continue as depository and a successor depository is not appointed by us within 90 days, we will issue individual debt securities of such series in exchange for the global security representing such series of debt securities. In addition, we may, at any time and in our sole discretion, subject to any limitations described in the applicable prospectus supplement relating to such debt securities, determine not to have any debt securities of such series represented by one or more global securities and, in such event, will issue individual debt securities of such series in exchange for the global security or securities representing such series of debt securities.

Payment and Paying Agents

We will pay principal and any premium or interest on a debt security to the person in whose name the debt security is registered at the close of business on the regular record date for such interest.

We will pay principal and any premium or interest on the debt securities at the office of our designated paying agent. Unless the prospectus supplement indicates otherwise, the trustee will act as our paying agent.

Any other paying agents we designate for the debt securities of a particular series will be named in the prospectus supplement. We may designate additional paying agents, rescind the designation of any paying agent or approve a change in the office through which any paying agent acts, but we must maintain a paying agent in each place of payment for the debt securities.

The paying agent will return to us all money we pay to it for the payment of the principal, premium or interest on any debt security that remains unclaimed for a specified period. Thereafter, the holder may look only to us for payment, as an unsecured general creditor.

13

Limitation on Mergers and Consolidations

So long as any debt securities of a series remain outstanding, we may not consolidate or merge with or into any Person, or sell, lease, convey or otherwise dispose of all or substantially all of our assets, or assign any of our obligations under an indenture or the debt securities, to any Person, unless:

The Successor shall be the successor to us and shall succeed to, and be substituted for, and may exercise every right and power of, us under the indenture, and we (except in the case of a lease) shall be released from the obligation to pay the principal of and interest on the debt securities.

Events of Default

Each of the following will constitute an Event of Default under each indenture with respect to each series of debt securities:

After the occurrence of an Event of Default, the trustee is required to transmit notice thereof to the holders of the debt securities within 60 days after it occurs or promptly upon the trustee attaining knowledge thereof, whichever is earlier. Except in the case of a default in the payment of the principal of or interest on the debt securities, the trustee may withhold such notice if and so long as the trustee, in good faith, determines that the withholding of such notice is in the interests of the holders of the debt securities. If an Event of Default (other than the bankruptcy provision) occurs and is continuing with respect to a series of debt securities, the trustee or the holders of at least 25% in aggregate principal amount of the outstanding debt securities of that series may declare

14

the principal of and accrued but unpaid interest on all the debt securities of that series immediately due and payable. If a bankruptcy event occurs, the principal of and accrued and unpaid interest on all the debt securities shall become immediately due and payable without any declaration or other act on the part of the trustee or any holders of such debt securities. However, if prior to the entry of any judgment or decree for the accelerated amount, we shall pay or deposit with the trustee all principal and interest in arrears, the holders of not less than a majority in aggregate principal amount of the outstanding debt securities of a series shall have the right to waive all defaults and the consequences of having all principal payments due. This waiver will not, however, be operative as against nor impair any rights arising as a result of any subsequent Event of Default. The trustee will not be charged with knowledge of any Event of Default other than our failure to make principal and interest payments unless actual written notice thereof is received by the trustee.

The indenture contains provisions regarding limitations on the right to institute legal proceedings. No holder of debt securities of a series shall have the right to institute an action or proceeding for rights arising under the indenture unless:

Notwithstanding the foregoing, subject to applicable law, nothing shall prevent the holders of debt securities of a series from enforcing payment of the principal of or interest on their debt securities.

The holders of a majority in aggregate principal amount of the outstanding debt securities of a series 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 debt securities of that series. The trustee, however, may refuse to follow such direction if the trustee determines that the action so directed may not lawfully be taken, or that the action so directed would be unduly prejudicial to the holders of the debt securities of a series not taking part in such action or that such action would involve the trustee in personal liability.

The indenture provides that, in case an Event of Default shall occur (which shall not have been cured or waived), the trustee will be required to use the degree of care a prudent person would use in the conduct of their own affairs. Subject to such provisions, the trustee will be under no obligation to exercise any of its rights or powers under the indenture at the request of any of the holders of the debt securities of a series unless they shall have offered the trustee security or indemnity satisfactory to it.

We will be required to furnish to the trustee annually a statement as to the fulfillment by us of all our obligations under the indenture. In addition, we are required to notify the trustee of the occurrence of certain events of default in accordance with the indenture.

Supplemental Indentures

We and the trustee may enter into supplemental indentures and indentures without the consent of any holders of debt securities with respect to specific matters, including:

15

In addition, under the indentures, the rights of holders of a series of debt securities may be changed by us and the trustee with the written consent of the holders of at least a majority in aggregate principal amount of the outstanding debt securities of each series that is affected. However, we and the trustee may only make the following changes with the consent of the holder of each debt security affected:

The holders of a majority in principal amount of the outstanding debt securities of any series may waive any past default under the indenture with respect to debt securities of that series, except a default in the payment of principal, premium or interest on any debt security of that series or in respect of a covenant or provision of the indenture that cannot be amended without each holder’s consent.

Except in limited circumstances, we may set any day as a record date for the purpose of determining the holders of outstanding debt securities of any series entitled to give or take any direction, notice, consent, waiver, or other action under the indentures. In limited circumstances, the trustee may set a record date. To be effective, the action must be taken by holders of the requisite principal amount of such debt securities within a specified period following the record date.

Defeasance; Satisfaction and Discharge

Unless otherwise provided in the prospectus supplement, at any time, we may terminate all of our obligations under a series of debt securities and our obligations under an indenture with respect to that series of debt securities, or “legal defeasance,” except for certain obligations, including those respecting the defeasance trust and obligations to register the transfer or exchange of the debt securities of a series, to replace mutilated, destroyed, lost, or stolen debt securities and to maintain a registrar and paying agent in respect of the debt securities.

In addition, unless otherwise provided in the prospectus supplement, at any time we may terminate with respect to any series of senior debt securities our and our Subsidiaries’ obligations under certain covenants as described in any prospectus supplement.

16

We may exercise our legal defeasance option with respect to a series of senior debt securities notwithstanding the prior exercise of our covenant defeasance option. If we exercise our legal defeasance option, payment of the debt securities of a series may not be accelerated because of an event of default with respect thereto. If we exercise our covenant defeasance option with respect to a series of senior debt securities, payment of the debt securities may not be accelerated because of an event of default specified in clause (4) under “—Events of Default” above due to a violation of covenants.

In order to exercise either of our defeasance options as to debt securities of a series, we must irrevocably deposit in trust (the “defeasance trust”) with the trustee money or Governmental Obligations sufficient to pay all remaining principal and interest on the debt securities, and must comply with certain other conditions, including delivery to the trustee of an opinion of counsel to the effect that holders of the debt securities of such series will not recognize income, gain, or loss for Federal income tax purposes as a result of such deposit and defeasance and will be subject to Federal income tax on the same amounts and in the same manner and at the same times as would have been the case if such deposit and defeasance had not occurred (and, in the case of legal defeasance only, such opinion of counsel must be based on a ruling received from or published by the Internal Revenue Service or other change in applicable Federal income tax law).

Our obligations under the applicable indenture will cease to be of further effect with respect to a series of debt securities when either (1) all securities of that series have been delivered (except lost, stolen, or destroyed securities that have been replaced or paid and the securities for whose payment money or noncallable government obligations has theretofore been deposited in trust or segregated and held in trust by the company and thereafter repaid to us or discharged from such trust in accordance with the indenture) to the trustee for cancellation, or (2) all such securities not theretofore delivered to the trustee for cancellation have become due and payable, will become due and payable within one year or are to be called for redemption within one year under arrangements satisfactory to the trustee for the giving of notice of redemption and we have deposited or caused to be deposited with the trustee, in trust, money, noncallable government obligations or a combination thereof, in an amount sufficient in the opinion of a nationally recognized firm of independent public accountants to pay and discharge the entire indebtedness on such debt securities not theretofore delivered to the trustee for cancellation, for principal (and premium, if any) and interest, to the date of maturity or date of redemption, as the case may be;

Regarding the Trustee

The trustee for the senior debt securities is U.S. Bank National Association, which maintains its corporate trust offices at 214 N. Tryon Street, 26th Floor, Charlotte, North Carolina 28202. The trustee provides certain corporate trust services to us in the ordinary course of business and may provide such services in the future. In addition, the trustee serves as the trustee with respect to numerous other notes, including notes issued pursuant to the senior debt securities. The indenture for the senior debt securities and provisions of the Trust Indenture Act contain limitations on the rights of the trustee, should it become one of our creditors, to obtain payment of claims in certain cases, or to realize on certain property received by it in respect of any such claims as security or otherwise. The trustee is permitted to engage in other transactions. However, if the trustee acquires any conflicting interest it must either eliminate such conflict, apply to the SEC for permission to continue or resign. Further information regarding the trustee for senior debt securities may be provided in an applicable prospectus supplement.

17

Further information regarding the trustee for subordinated debt securities will be provided in an applicable prospectus supplement.

Governing Law

The indentures and the debt securities will be governed by and construed in accordance with the laws of the State of New York.

Limitations of Director Liability

Delaware law authorizes corporations to limit or eliminate the personal liability of directors to corporations and their stockholders for monetary damages for breach of directors’ fiduciary duty of care. Although Delaware law does not change directors’ duty of care, it enables corporations to limit available relief to equitable remedies such as injunction or rescission. Our certificate of incorporation limits the liability of directors to us and our stockholders to the full extent permitted by Delaware law. Specifically, directors are not personally liable for monetary damages to us or our stockholders for breach of the director’s fiduciary duty as a director, except for liability for:

Indemnification

To the maximum extent permitted by law, our certificate of incorporation provides for mandatory indemnification of directors and officers against any expense, liability or loss to which they may become subject, or which they may incur as a result of being or having been a director or officer. In addition, we must advance or reimburse directors and officers for expenses they incur in connection with indemnifiable claims. We also maintain directors’ and officers’ liability insurance.

We will file a copy of the certificate of designations that contains the terms of each new series of preferred stock with the SEC each time we issue a new series of preferred stock, and these certificates of designations will be incorporated by reference into the registration statement of which this prospectus is a part. Each certificate of designation will establish the number of shares included in a designated series and fix the designations, powers, privileges, preferences, and rights of the shares of each series as well as any applicable qualifications, limitations, or restrictions. For the complete terms of our preferred stock, in addition to the applicable certificate of designations, please refer to our certificate of incorporation and bylaws that are filed as exhibits to our reports incorporated by reference into the registration statement that includes this prospectus. The General Corporation Law of Delaware, as amended, may also affect the terms of our preferred stock.

20

Other

DESCRIPTION OF WARRANTS

The following description, together with the additional information we may include in any applicable prospectus supplement, summarizes the material terms and provisions of the warrants that may be offered under this prospectus and the related warrant agreements and warrant certificates. While the terms summarized below will apply generally to any warrants we may offer, we will describe the particular terms of any series of warrants in more detail in the applicable prospectus supplement.

General

We may issue warrants for the purchase of our senior or subordinated debt securities, common stock or preferred stock, or any combination of those securities in the form of units. We may issue warrants independently or together with other securities, and they may be attached to or separate from the other securities. Each series of warrants may be issued under a separate warrant agreement that we will enter into with a bank or trust company, as warrant agent, as detailed in the applicable prospectus supplement. The warrant agent will act solely as our agent in connection with the warrants and will not assume any obligation, or agency or trust relationship, with you. We will file a copy of the warrant and warrant agreement with the SEC each time we issue a series of warrants, and these warrants and warrant agreements will be incorporated by reference into the registration statement of which this prospectus is a part. You should refer to the provisions of the applicable warrant agreement and prospectus supplement for more specific information.

The prospectus supplement relating to a particular issue of warrants will describe the terms of those warrants, including, where applicable:

21

Before exercising our warrants, a holder of our warrants will not have any of the rights of holders of the securities purchasable upon such exercise, including the right to receive dividends, if any, or payments upon our liquidation, dissolution or winding up or to exercise voting rights, if any.

Exercise of Warrants

Each warrant will entitle the holder thereof to purchase for cash or other consideration specified in an applicable prospectus supplement the amount of debt securities, the number of shares of preferred stock and the number of shares of common stock at the exercise price as shall in each case be set forth in, or be determinable as set forth in, the applicable prospectus supplement. Warrants may be exercised at any time up to the close of business on the expiration date set forth in the applicable prospectus supplement. After the close of business on the expiration date, unexercised warrants will become void.

Warrants may be exercised as set forth in the applicable prospectus supplement relating to the warrants offered thereby. Upon receipt of payment and the warrant certificate properly completed and duly executed at the corporate trust office of the warrant agent or any other office indicated in the applicable prospectus supplement, we will, as soon as practicable, forward the purchased securities. If less than all of the warrants represented by the warrant certificate are exercised, a new warrant certificate will be issued for the remaining warrants. Holders of warrants will be required to pay any tax or governmental charge that may be imposed in connection with transferring the underlying securities in connection with the exercise of the warrants.

Enforceability of Rights of Holders of Warrants

Each warrant agent will act solely as our agent under the applicable warrant agreement and will not assume any obligation or relationship of agency or trust with any holder of any warrant. A single bank or trust company may act as a warrant agent for more than one series of warrants. A warrant agent will have no duty or responsibility in case of any default by us under the applicable warrant agreement or warrant, including any duty or responsibility to initiate any proceedings at law or otherwise, or to make any demand upon us. Any holder of a warrant may, without the consent of the related warrant agent or the holder of any other warrant, enforce by appropriate legal action its right to exercise, and receive the securities purchasable upon exercise of, that holder’s warrants.

DESCRIPTION OF UNITS

We may issue units comprising one or more of the other securities described in this prospectus in any combination. The unit agreement under which a unit is issued may provide that the securities included in the unit may not be held or transferred separately at any time or at any time before a specified date.

PART II

INFORMATION NOT REQUIRED IN PROSPECTUS

The following table sets forth an estimate, subject to future contingencies, of the fees and expenses to be incurred in connection with the issuance and distribution of the securities being registered, other than underwriting discounts and commissions, if any.

As authorized by Section 145 of the General Corporation Law of the State of Delaware (“Delaware Corporation Law”), each director and officer of the registrant may be indemnified by the registrant against expenses (including attorney’s fees), judgments, fines, and amounts paid in settlement actually and reasonably incurred in connection with the defense or settlement of any threatened, pending, or completed legal proceedings in which he/she is involved by reason of the fact that he/she is or was a director or officer of the registrant; provided that he/she acted in good faith and in a manner that he/she reasonably believed to be in or not opposed to the best interest of the registrant; and, with respect to any criminal action or proceeding, that he/she had no reasonable cause to believe that his/her conduct was unlawful. If the legal proceeding, however, is by or in the right of the registrant, the director or officer may not be indemnified in respect of any claim, issue, or matter as to which he shall have adjudged to be liable for negligence or misconduct in the performance of his duty to the registrant unless a court determines otherwise.

Section 102(b)(7) of the Delaware Corporation Law provides that a corporation may eliminate or limit 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) for willful or negligent conduct in paying dividends or repurchasing or redeeming stock out of other than lawfully available funds (pursuant to Section 174 of the Delaware Corporation Law), or (iv) for any transaction from which the director derived an improper personal benefit. No such provision shall eliminate or limit the liability of a director for any act or omission occurring prior to the date when such provision becomes effective.

Article Five of the restated certificate of incorporation of the registrant provides that no director of the registrant shall be personally liable to the registrant or its stockholders for monetary damages for any breach of his/her fiduciary duty as director; provided, however, that such clause shall not apply to any liability of a director (i) for

II-1

any breach of such director’s duty of loyalty to the registrant or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) pursuant to Section 174 of the Delaware Corporation Law, or (iv) for any transaction from which the director derived an improper personal benefit. In addition, the provisions of Article VII of the registrant’s amended and restated by-laws provide that the registrant shall indemnify persons entitled to be indemnified to the fullest extent permitted by the Delaware Corporation Law.

The registrant maintains policies of officers’ and directors’ liability insurance in respect of acts or omissions of current and former officers and directors of the registrant, its subsidiaries, and “constituent” companies that have been merged with the registrant.

II-2

(a) The undersigned registrant hereby undertakes:

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i) to include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;

(ii) to reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated

II-3

maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20 percent change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and

(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), (ii) and (iii) do not apply if the registration statement is on Form S-3 and 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 Securities Exchange Act of 1934 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 part of the registration statement.

(2) That, for the purpose of determining any liability under the Securities Act of 1933, 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.

(4) [Reserved]

(5) That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser:

(i) if the registrant is relying on Rule 430B:

(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 of 1933 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 the 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 of 1933 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

II-4

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;

(ii) Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

(iii) The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

(iv) Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

(b) The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant’s annual report pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in this registration statement 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.

(h) Insofar as indemnification for liabilities arising under the Securities Act of 1933 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 of 1933 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 of 1933 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 of 1939 in accordance with the rules and regulations prescribed by the SEC under Section 305(b)(2) of the Trust Indenture Act of 1939.

committee of such board (“Board Action”) consistent with the procedures and terms described in the Registration Statement and in accordance with the Company’s charter and bylaws and applicable Delaware corporate law, in a manner that does not violate any law, government or court-imposed order or restriction or agreement or instrument then binding on the Company or otherwise impair the legal or binding nature of the obligations represented by the applicable Securities; (ii) at the time of offer, issuance and sale of any Securities, the Registration Statement will have been declared effective under the Securities Act of 1933, as amended (the “Act”), and no stop order suspending its effectiveness will have been issued and remain in effect; (iii) any senior Debt Securities will be issued pursuant to the indenture filed as Exhibit 4.04 to the Registration Statement, and any subordinated Debt Securities will be issued pursuant to a subordinated indenture, substantially in the form of such indenture filed as Exhibit 4.16 to the Registration Statement, with items shown in such exhibit as subject to completion completed in a satisfactory manner; (iv) the indentures under which any Debt Securities are issued will be qualified under the Trust Indenture Act of 1939, as amended; (v) any Warrants will be issued under one or more warrant agreements, each to be between the Company and a financial institution identified therein as a warrant agent; (vi) prior to any issuance of Preferred Shares, appropriate certificates of designation will be accepted for record by the Secretary of State of the State of Delaware; (vii) any Units will be issued under one or more unit agreements, each to be between the Company and the financial institution identified therein as unit agent, (viii) if being sold by the issuer thereof, the Securities will be delivered against payment of valid consideration therefor and in accordance with the terms of the applicable Board Action authorizing such sale and any applicable underwriting agreement or purchase agreement and as contemplated by the Registration Statement and/or the applicable prospectus supplement; (ix) the Company will remain a Delaware corporation; and (x) the Securities will not be issued in violation of the ownership limit contained in the Company’s charter.

To the extent that the obligations of the Company with respect to the Securities may be dependent upon such matters, we assume for purposes of this opinion that the other party under the indenture for any Debt Securities, under the warrant agreement for any Warrants and under the unit agreement for any Units, namely, the trustee, the warrant agent or the unit agent, respectively, is duly organized, validly existing and in good standing under the laws of its jurisdiction of organization; that such other party is duly qualified to engage in the activities contemplated by such indenture, warrant agreement or unit agreement, as applicable; that such indenture, warrant agreement or unit agreement, as applicable, has been duly authorized, executed and delivered by the other party and constitutes the legal, valid and binding obligation of the other party enforceable against the other party in accordance with its terms; that such other party is in compliance with respect to performance of its obligations under such indenture, warrant agreement or unit agreement, as applicable, with all applicable laws, rules and regulations; and that such other party has the requisite organizational and legal power and authority to perform its obligations under such indenture, warrant agreement or unit agreement, as applicable.

This opinion letter is based as to matters of law solely on the applicable provisions of the following, as currently in effect: (i) as to the opinions given in paragraphs (b), (c) and (d), the Delaware General Corporation Law, as amended, and (ii) as to the opinions given in paragraphs (a), (d) and (e), the laws of the State of New York (but not including any laws, statutes, ordinances, administrative decisions, rules or regulations of any political subdivision below the state level). We express no opinion herein as to any other statutes, rules or regulations (and in particular, we express no opinion as to any effect that such other statutes, rules or regulations may have on the opinions

expressed herein). As used herein, the term “Delaware General Corporation Law, as amended” includes the statutory provisions contained therein, all applicable provisions of the Delaware Constitution and reported judicial decisions interpreting these laws.

Based upon, subject to and limited by the foregoing, we are of the opinion that:

(a) The Debt Securities (including any Debt Securities duly issued as part of any Units or upon the exercise of Warrants), upon due execution and delivery of an indenture relating thereto on behalf of the Company and the trustee named therein, and upon authentication by such trustee and due execution and delivery on behalf of the Company in accordance with the indenture and any supplemental indenture relating thereto, will constitute valid and binding obligations of the Company.

(b) The Preferred Shares (including any Preferred Shares duly issued as part of any Units or upon the exercise of Warrants and receipt by the Company of any additional consideration payable upon such exercise), upon due execution and delivery on behalf of the Company of certificates therefor, will be validly issued, fully paid and nonassessable.

(c) The Common Shares (including any Common Shares duly issued as part of any Units or upon the exchange or conversion of Debt Securities or Preferred Shares that are exchangeable for or convertible into Common Shares or upon the exercise of Warrants and receipt by the Company of any additional consideration payable upon such conversion, exchange or exercise), upon due execution and delivery on behalf of the Company of certificates for Common Shares, will be validly issued, fully paid and nonassessable.

(d) The Warrants, upon due execution and delivery of a warrant agreement relating thereto on behalf of the Company and the warrant agent named therein and due authentication of the Warrants by such warrant agent, and upon due execution and delivery of the Warrants on behalf of the Company, will constitute valid and binding obligations of the Company.

(e) The Units, upon due execution and delivery of a unit agreement relating thereto on behalf of the Company and the unit agent named therein, upon due authentication of the Units by such unit agent and upon due execution and delivery of the underlying Securities that are components of the Units in accordance with the applicable unit agreement and the applicable indenture (in the case of underlying Debt Securities), certificates of designation (in the case of underlying Preferred Shares), or warrant agreement (in the case of underlying Warrants), will constitute valid and binding obligations of the Company.

The opinions expressed in Paragraphs (a), (d) and (e) above with respect to the valid and binding nature of obligations may be limited by bankruptcy, insolvency, reorganization, receivership, moratorium or other laws affecting creditors’ rights (including, without limitation, the effect of statutory and other law regarding fraudulent conveyances, fraudulent transfers and preferential transfers) and by the exercise of judicial discretion and the application of principles of equity, good faith, fair dealing, reasonableness, conscionability and materiality (regardless of whether the Securities are considered in a proceeding in equity or at law).

This opinion letter has been prepared for use in connection with the Registration Statement. We assume no obligation to advise of any changes in the foregoing subsequent to the effective date of the Registration Statement.

We hereby consent to the filing of this opinion letter as Exhibit 5.01 to the Registration Statement and to the reference to this firm under the caption “Legal Matters” in the prospectus constituting a part of the Registration Statement. In giving this consent, we do not thereby admit that we are an “expert” within the meaning of the Act.
