DESCRIPTION OF THE DEBT SECURITIES
 
We have summarized certain general terms and provisions of the debt securities that we may offer under this prospectus below. The particular terms of a series of debt securities offered by a prospectus supplement will be described in that prospectus supplement.
 
The debt securities will be issued under, and entitled to the benefits of, an indenture dated as of November 1, 2006 between us and Wells Fargo Bank, National Association, as trustee, which we refer to as the indenture.
 
We have summarized the material provisions of the indenture below. The following summary does not purport to be a complete description of the indenture and is subject to the detailed provisions of, and qualified in its entirety by reference to, the indenture, including any terms deemed to be a part thereof by the Trust Indenture Act of 1939. Capitalized terms used herein without definition have the respective meanings given such terms in the indenture. You may obtain a copy of the indenture as described under the headings “Where You Can Find More Information” and “Incorporation by Reference of Certain Documents.”
 
As used under this heading “Description of the Debt Securities,” the words “company,” “we,” “our,” “ours” and “us” refer to USG Corporation, the issuer of the debt securities, and not to any of its consolidated subsidiaries.
 
General
 
The indenture does not limit the aggregate principal amount of debt securities that we may issue. We may issue our debt securities from time to time in one or more series with the same or different terms. All debt securities of any one series need not be issued at the same time, and unless otherwise provided, a series of debt securities may be reopened, without the consent of the holders of outstanding debt securities, for issuances of additional debt securities of that series or to establish additional terms of that series of debt securities (with such additional terms applicable only to unissued or additional debt securities of that series). The terms of each series of debt securities will be established by or pursuant to a resolution of our board of directors and set forth in an officers’ certificate or in a supplemental indenture.
 
We will set forth the particular terms of debt securities we offer, as well as any modifications or additions to the general terms of the indenture, in a prospectus supplement relating to the offer of those debt securities, including some or all of the following terms, to the extent required:
 
  •     the title of the debt securities;
 
  •     any limit upon the aggregate principal amount of the debt securities that may be issued;
 
  •     the percentage of the principal amount at which the debt securities will be offered, if other than 100%;
 
  •     the date or dates on which the principal of the debt securities is payable;
 
  •     the rate or rates, which may be fixed or variable, at which the debt securities will bear interest, if any, the date or dates from which such interest will accrue, the interest payment dates on which such interest will be payable and the record dates for the determination of holders of the debt securities to whom interest is payable;
 
  •     the place or places where the principal and interest on the debt securities will be payable;
 
  •     whether any of the debt securities are to be redeemable at our option and, if so, the price or prices at which, the period or periods within which and the terms and conditions upon which the debt securities may be so redeemed, in whole or in part, at our option, pursuant to any sinking fund or otherwise;
 
  •     if other than the principal amount, the portion of the principal amount of debt securities that will be payable upon declaration of acceleration of the maturity upon occurrence of an event of default under the indenture;
 
  •     our obligation, if any, to redeem, purchase or repay the debt securities pursuant to any sinking fund or analogous provisions or at the option of a holder of debt securities and the price or prices at

Table of Contents

which, process by which, period or periods within which and terms and conditions upon which the debt securities will be redeemed, purchased or repaid, in whole or in part, pursuant to such obligation;
 
  •     if other than denominations of $1,000 and any integral multiple of $1,000, the denominations, which may be in U.S. dollars or any foreign currency, in which the debt securities will be issuable;
 
  •     the form of the debt securities, including such legends as required by law or as we deem necessary or appropriate and the form of any coupons or temporary global security that may be issued;
 
  •     if other than U.S. dollars, the currency or currencies in which payments of principal of or interest on the debt securities will be made or in which the debt securities will be denominated and the particular provisions applicable thereto;
 
  •     whether the debt securities of the series are issuable in tranches;
 
  •     whether, and under what circumstances, the debt securities of the series may be convertible into debt securities of any other series;
 
  •     if other than the Wells Fargo Bank, National Association, any trustees, authenticating or paying agents, transfer agents or registrars or any other agents with respect to the debt securities;
 
  •     any deletions from, modifications of or additions to the events of default or our covenants under the indenture;
 
  •     whether, under what circumstances and the currency in which we will pay additional amounts on the debt securities to non-U.S. holders of the debt securities in respect of any tax, assessment or governmental charge and, if so, whether we will have the option to redeem such debt securities rather than pay such additional amounts (and the terms of such option); and
 
  •     any other terms or conditions upon which the debt securities of the series are to be issued, which will not be inconsistent with the provisions of the indenture.
 
Unless otherwise indicated in the applicable prospectus supplement, we will issue debt securities in fully registered form without coupons and in denominations of $1,000 and in integral multiples of $1,000, and interest will be computed on the basis of a 360-day year of twelve 30-day months. If any interest payment date or the maturity date falls on a day that is not a Business Day, then the payment will be made on the next Business Day without additional interest and with the same effect as if it were made on the originally scheduled date. “Business Day” means any calendar day that is not a Saturday, Sunday or legal holiday in New York, New York, and on which commercial banks are open for business in New York, New York.
 
Unless otherwise indicated in the applicable prospectus supplement, principal of and interest and premium, if any, on the debt securities will be payable at the office of the trustee in Chicago, Illinois. Unless otherwise indicated in the applicable prospectus supplement, the trustee will act as paying agent and registrar under the indenture. We may act as paying agent or registrar under the indenture.
 
Covenants Contained in the Indenture
 
Limitation on Liens
 
The indenture provides that, so long as any of the debt securities remains outstanding, we will not and will not permit any Restricted Subsidiary to issue, assume or guarantee any indebtedness for money borrowed (“indebtedness”) that is secured by a mortgage, pledge, security interest or other lien or encumbrance (a “lien”) upon or with respect to any Principal Property or on the capital stock of any Restricted Subsidiary unless:
 
  •     we secure the debt securities equally and ratably with (or prior to) any and all other obligations and indebtedness secured by that lien; or
 
  •     the aggregate amount of all of our consolidated indebtedness secured by liens (other than permitted liens) on our Principal Properties or on the capital stock of our Restricted Subsidiaries, including all Attributable Debt in respect of sale and leaseback transactions existing at that time, would not exceed the greater of 15% of our Consolidated Net Tangible Assets and $200,000,000, with the exception of transactions that are not subject to the limitation described in “— Limitation on Sale and Leaseback Transactions” below.

Table of Contents

 
The above limitation will not apply to some types of permitted liens. Therefore, the indebtedness secured by those permitted liens is excluded in computing indebtedness for purposes of this limitation. These permitted liens include:
 
  •     liens existing as of the date of the indenture;
 
  •     liens on property or assets of, or any shares of stock or securing indebtedness of, any corporation existing at the time such corporation becomes a consolidated subsidiary;
 
  •     liens on property, assets, shares of stock or securing indebtedness existing at the time of an acquisition, including an acquisition through merger or consolidation, and liens to secure indebtedness incurred prior to, at the time of or within 180 days after the later of the completion of the acquisition, or the completion of the construction, improvement or renovation and commencement of the operation of, any such property, for the purpose of financing all or any part of the purchase price or construction cost of that property;
 
  •     liens to secure specified types of development, operation, construction, alteration, repair or improvement costs;

  •     certain types of liens in connection with legal proceedings and judgments;
 
  •     certain types of liens arising in the ordinary course of business and not in connection with the borrowing of money such as mechanics’, materialmen’s, carriers’, landlord’s or other similar liens;
 
  •     liens on property securing obligations issued by a domestic governmental issuer to finance the cost of an acquisition or construction of that property;
 
  •     extensions, substitutions, replacements or renewals of the foregoing if the principal amount of the indebtedness secured thereby is not increased and is not secured by any additional assets;
 
  •     liens currently or hereafter existing or arising securing indebtedness or any other obligations under the senior credit facility or any renewals, amendments, increases, extensions, replacements or refinancings thereof;
 
  •     liens arising from the granting of a license to any person in the ordinary course of business, provided that such liens attach only to the assets subject to such license;
 
  •     liens arising by operation of law or contract on insurance policies and the proceeds thereof to secure premiums thereunder;
 
  •     liens incurred with respect to rights of agents for collection for us under assignments of chattel paper, accounts, instruments or general intangibles for purposes of collection in the ordinary course of business;

  •     liens for taxes, assessments or other governmental charges; and
 
  •     easements, zoning restrictions, rights of way and similar encumbrances on real property that do not secure monetary obligations.
 
Limitation on Sale and Leaseback Transactions
 
The indenture provides that, so long as any of the debt securities remains outstanding, neither we nor any Restricted Subsidiary may enter into any arrangement with any person (other than among ourselves and/or our Restricted Subsidiaries) where we or a Restricted Subsidiary agree to lease any Principal Property which has


6


Table of Contents

been or is to be sold or transferred more than 180 days after the later of (1) such Principal Property has been acquired by us or a Restricted Subsidiary and (2) completion of construction and commencement of full operation thereof, by us or a Restricted Subsidiary to that person (a “Sale and Leaseback Transaction”). Sale and Leaseback Transactions with respect to facilities financed with specified tax exempt securities are excepted from the definition. This covenant does not apply to leases of a Principal Property for a term of less than three years.
 
This limitation also does not apply to any Sale and Lease-Back Transaction if:
 
  •     the net proceeds to us or a Restricted Subsidiary from the sale or transfer equal or exceed the fair value, as determined by our board of directors, of the Principal Property so leased;
 
  •     we or the Restricted Subsidiary could incur indebtedness secured by a lien on the Principal Property to be leased pursuant to the terms discussed in “— Limitation on Liens” above in an amount equal to the Attributable Debt with respect to the Sale and Leaseback Transaction without equally and ratably securing the senior debt securities; or
 
  •     we or our Restricted Subsidiaries within 180 days after the effective date of the Sale and Leaseback Transaction apply an amount equal to the fair value as determined by our board of directors of the Principal Property so leased to:
 
  •     the prepayment or retirement of our Funded Debt, which may include debt securities; provided, however, that in lieu of applying all or any part of such net proceeds or fair market value to such retirement, we may at our option (1) deliver to the Trustee debt securities previously purchased or otherwise acquired by us or (2) receive credit for debt securities previously redeemed by us, which, in either case, have not previously been applied by us in lieu of retiring Funded Debt as required pursuant to this restriction. If we shall so deliver such debt securities to the Trustee (or receive credit for debt securities so delivered), the amount of cash which we shall be required to apply to the retirement of Funded Debt pursuant to this restriction shall be reduced by an amount equal to the aggregate principal amount of such debt securities; or
 
  •     the acquisition of additional real property.
 
Certain Definitions
 
The terms set forth below are defined in the indenture as follows:
 
“Attributable Debt,” in respect of the Sale and Leaseback Transactions described above, means as of any particular time, the present value, calculated using a rate of interest implicit in such transaction determined in accordance with generally accepted accounting principles in the United States, of the obligation of a lessee for rental payments during the remaining term of any lease, including any period for which that lease has been extended or may, at the option of the lessor, be extended after excluding all amounts required to be paid in respect of maintenance and repairs, insurance, taxes, assessments, water and utility rates, management fees and similar charges.
 
“Consolidated Net Tangible Assets” means the aggregate amount of assets, reduced by applicable reserves and other properly deductible items, after deducting:
 
  •     all current liabilities, excluding the current portion of any Funded Debt and any other current liabilities constituting Funded Debt because it is extendible or renewable; and
 
  •     all goodwill, trade names, trademarks, patents, unamortized debt discount and expense and other similar intangibles,
 
all as set forth on our books and records and those of our consolidated subsidiaries and computed in accordance with generally accepted accounting principles in the United States.
 
“Funded Debt” means all indebtedness (other than intercompany indebtedness among us and our subsidiaries) for the repayment of money borrowed, whether or not evidenced by a bond, debenture, note or similar instrument or agreement, having a final maturity of more than 12 months after the date of its creation or having a final maturity of less than 12 months after the date of its creation but by its terms being renewable or extendible beyond 12 months after such date at the option of the borrower (excluding obligations under Capital Leases). When determining “Funded Debt,” indebtedness will not be included if, on or prior to the final maturity

of that indebtedness, we have deposited the necessary funds for the payment, redemption or satisfaction of that indebtedness in trust with the proper depositary.
 
“Principal Property” means, as of any date any lien thereon is to become effective, any building, structure or other facility, together with the land upon which it is erected and any fixtures which are a part of the building, structure or other facility, used primarily for manufacturing, processing or production (other than any such land, building, structure or other facility or portion thereof which is a pollution control facility or sewage or waste disposal facility), in each case located in the United States, and owned or leased or to be owned or leased by us or any consolidated subsidiary, and in each case the net book value of which as of that date exceeds 1% of our Consolidated Net Tangible Assets as shown on the consolidated balance sheet contained in our then latest filing with the SEC, other than any such land, building, structure or other facility or portion thereof which is financed through the issuance of tax-exempt government obligations or which in the opinion of our board of directors, is not of material importance to the total business conducted by us and our consolidated subsidiaries, considered as one enterprise.
 
“Restricted Subsidiary” means a subsidiary of our company that owns a Principal Property.
 
Restrictions on Mergers and Sales of Assets
 
The indenture permits a consolidation or merger between us and another entity and/or the sale or transfer by us of all or substantially all of our property and assets, provided that:
 
  •     the resulting or acquiring entity, if other than us, is organized and existing under the laws of a U.S. jurisdiction and assumes all of our responsibilities and liabilities under the indenture, including the payment of all amounts due on the debt securities and performance of the covenants in the indenture;
 
  •     immediately after the transaction, and giving effect to the transaction, no event of default under the indenture exists;
 
  •     as a result of such transaction, our properties or assets or Restricted Subsidiaries’ properties or assets would become subject to a lien not permitted pursuant to the provisions discussed above under the heading “— Limitation on Liens” without equally and ratably securing the debt securities, steps shall have been taken to secure the debt securities equally and ratably with all indebtedness secured by such lien; and
 
  •     we have delivered to the trustee an officers’ certificate and an opinion of counsel, each stating that the transaction and, if a supplemental indenture is required in connection with the transaction, the supplemental indenture comply with the indenture and that all conditions precedent to the transaction contained in the indenture have been satisfied.
 
If we consolidate or merge with or into any other entity or sell or lease all or substantially all of our assets according to the terms and conditions of the indenture, the resulting or acquiring entity will be substituted for us in the indenture with the same effect as if it had been an original party to the indenture. As a result, such successor entity may exercise our rights and powers under the indenture, in our name and, except in the case of a lease, we will be released from all our liabilities and obligations under the indenture and under the debt securities.
 
Notwithstanding the foregoing provisions, we may transfer all of our property and assets to another corporation if, immediately after giving effect to the transfer, such corporation is our Wholly Owned Restricted Subsidiary (as defined below).
 
The term “Wholly Owned Restricted Subsidiary” means any Restricted Subsidiary in which we and/or our other wholly owned restricted subsidiaries own all of the outstanding capital stock (other than directors’ qualifying shares).

Modification and Waiver
 
Under the indenture, certain of our rights and obligations and certain of the rights of the holders of the debt securities may be modified or amended with the consent of the holders of not less than a majority of the total principal amount of the outstanding debt securities affected by the modification or amendment. However, the following modifications and amendments will not be effective against any holder without its consent:
 
  •     a change in the stated maturity date of any payment of principal or interest;
 
  •     a reduction in the principal amount of, or premium or interest on, any debt securities;
 
  •     a change in place of payment where, or the currency in which, any payment on the debt securities is payable;
 
  •     an impairment of a holder’s right to sue us for the enforcement of payments due on the debt securities; or
 
  •     a reduction in the percentage of outstanding debt securities required to consent to a modification or amendment of the indenture or required to consent to a waiver of compliance with certain provisions of the indenture or certain defaults under the indenture.
 
Under the indenture, the holders of at least a majority of the total principal amount of the outstanding debt securities may, on behalf of all holders of the debt securities:
 
  •     waive compliance by us with certain restrictive provisions of the indenture; and
 
  •     waive any past default under the indenture, except:
 
  •     a default in the payment of the principal of, or any premium or interest on, any debt securities; or
 
  •     a default under any provision of the indenture which itself cannot be modified or amended without the consent of the holders of each outstanding debt security.
 
Events of Default
 
“event of default,” when used in the indenture, means any of the following:
 
  •     failure to pay interest on any debt securities for 30 days after the payment is due;
 
  •     failure to pay the principal of, or any premium on, any debt security when due;
 
  •     failure to perform any other covenant in the indenture that applies to the debt securities for 60 days after we have received written notice of the failure to perform in the manner specified in the indenture;
 
  •     there occurs any default under any debt of the company having an outstanding principal amount in excess of $50 million in the aggregate which, as a result thereof, the holder(s) of such debt or a trustee or agent acting on their behalf have declared such debt to be due prior to its stated maturity date, or the company is required to repurchase or redeem such debt prior to its stated maturity and, in either case, such debt has not been discharged in full or such acceleration or redemption has not been rescinded or annulled within 30 days of the effectiveness thereof; or
 
  •     certain events in bankruptcy, insolvency or reorganization.
 
If an event of default occurs and continues, the trustee or the holders of at least 25% in aggregate principal amount of the outstanding debt securities may declare the entire principal of all the debt securities to be due and payable immediately, except that, if the event of default is caused by certain events in bankruptcy, insolvency or reorganization, the entire principal of all of the debt securities will become due and payable immediately without any act on the part of the trustee or holders of the debt securities. If such a declaration occurs, the holders of a majority of the aggregate principal amount of the outstanding debt securities can, subject to conditions, rescind the declaration.
 
The indenture requires us to file an officers’ certificate with the trustee each year that states, to the knowledge of the certifying officer, no defaults exist under the terms of the indenture. The trustee may withhold

Table of Contents

notice to the holders of debt securities of any default, except defaults in the payment of principal, premium, interest, if it considers the withholding of notice to be in the best interests of the holders. For purposes of this paragraph, “default” means any event which is, or after notice or lapse of time or both would become, an event of default under the indenture.
 
The trustee is not obligated to exercise any of its rights or powers under the indenture at the request, order or direction of any holders of debt securities, unless the holders offer the trustee reasonable indemnification. If reasonable indemnification is provided, then, subject to other rights of the trustee, the holders of a majority in aggregate principal amount of the outstanding debt securities 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 upon the trustee.
 
The holder of a debt security will have the right to begin any proceeding with respect to the indenture or for any remedy only if:
 
  •     the holder has previously given the trustee written notice of a continuing event of default;
 
  •     the holders of at least 25% in aggregate principal amount of the outstanding debt securities have made a written request of, and offered reasonable indemnification to, the trustee to begin such proceeding;
 
  •     the trustee has not started such proceeding within 60 days after receiving the request; and
 
  •     the trustee has not received directions inconsistent with such request from the holders of a majority in aggregate principal amount of the outstanding debt securities during those 60 days.
 
However, the holder of any debt security will have an absolute right to receive payment of principal of, and any premium and interest on, the debt security when due and to institute suit to enforce this payment.
 
Defeasance and Discharge
 
Defeasance and Discharge
 
We will be discharged from our obligations on the debt securities if:
 
  •     we deposit with the trustee, in trust, sufficient money or U.S. Government Obligations, or a combination, to pay the principal, any interest, any premium and any other sums due on the debt securities, on the dates the payments are due under the indenture and the terms of the debt securities;
 
  •     we deliver to the trustee an opinion of counsel that states that the holders of the debt securities will not recognize income, gain or loss for federal income tax purposes as a result of the deposit 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 no deposit had been made; and
 
  •     we deliver to the trustee an opinion of counsel that states that if the debt securities are listed on any domestic or foreign securities exchange, the debt securities will not be delisted as a result of the deposit.
 
The term “U.S. Government Obligations” means direct obligations of the United States of America backed by the full faith and credit of the United States.
 
In the event that we deposit money and/or U.S. Government Obligations in trust and discharge our obligations under debt securities as described above, then:
 
  •     the indenture will no longer apply to the debt securities; however, certain obligations to compensate, reimburse and indemnify the trustee, to register the transfer and exchange of debt securities, to replace lost, stolen or mutilated debt securities and to maintain paying agencies and the trust funds will continue to apply; and


10


Table of Contents

 
  •     holders of debt securities can only look to the trust fund for payment of principal of, or any premium or interest on, the debt securities.
 
Defeasance of Certain Covenants and Certain Events of Default
 
If we make the deposit and deliver the opinion of counsel described under the heading “— Defeasance and Discharge” above, we will not have to comply with the restrictive covenants contained in the indenture.
 
In the event of a defeasance, our obligations under the indenture and the debt securities, other than with respect to the restrictive covenants and related events of default specifically referred to above, will remain in effect.
 
If we exercise our option not to comply with the covenants listed above and the debt securities become immediately due and payable because an event of default has occurred, other than as a result of the event of default specifically referred to above, the amount of money and/or U.S. Government Obligations on deposit with the trustee will be sufficient to pay amounts due on the debt securities on the date the payments are due under the indenture and the terms of the debt securities, but may not be sufficient to pay amounts due at the time of acceleration. However, we would remain liable for the balance of the payments.
 
Substitution of Collateral
 
We can, at any time, withdraw any money or U.S. Government Obligations deposited pursuant to the defeasance provisions described above if we simultaneously substitute other money and/or U.S. Government Obligations which would satisfy our payment obligations on the debt securities pursuant to the defeasance provisions applicable to the debt securities.
 
Global Debt Securities and Book-Entry System
 
Unless otherwise indicated in the applicable prospectus supplement, debt securities issued will be in book-entry form and will be represented by one or more permanent global certificates in fully registered form without interest coupons (the “Global Debt Securities”) and will be deposited with the trustee as custodian for a depositary (the “Depositary”), which shall initially shall be DTC, and registered in the name of Cede & Co. as nominee of DTC or another nominee designated by DTC (such nominee being referred to herein as the “Global Debt Security Holder”).
 
Beneficial interests in the Global Debt Securities may not be exchanged for Certificated Debt Securities (as defined below) except in the circumstances described below.
 
DTC is a limited-purpose trust company that was created to hold securities for its participating organizations (“Participants”), and to facilitate the clearance and settlement of transactions in these securities between Participants through electronic book-entry changes in accounts of its Participants. The Participants include securities brokers and dealers, banks and trust companies, clearing corporations and certain other organizations. Access to DTC’s system is also available to other entities such as banks, brokers, dealers and trust companies (“Indirect Participants”) that clear through or maintain a custodial relationship with a Participant, either directly or indirectly. Persons who are not Participants may beneficially own securities held by or on behalf of DTC only through Participants or Indirect Participants. Pursuant to procedures established by DTC, ownership of the debt securities will be shown on, and the transfer of ownership of the debt securities will be effected only through, records maintained by DTC (with respect to the interests of Participants) and the records of Participants (with respect to the interests of Indirect Participants).
 
The laws of some states require that certain persons take physical delivery in definitive form of securities that they own. Consequently, the ability to transfer the debt securities will be limited to such extent.
 
So long as the Global Debt Security Holder is the registered owner of any debt securities, the Global Debt Security Holder will be considered the sole Holder of outstanding debt securities represented by such Global Debt Securities under the indenture. Except as provided below, owners of debt securities will not be entitled to have the debt securities registered in their names and will not be considered the owners or holders there of those debt securities under the indenture for any purpose, including with respect to the giving of any directions, instructions or approvals to the trustee thereunder. Neither we nor the trustee will have any


11


Table of Contents

responsibility or liability for any aspect of the records relating to or payments made on account of debt securities by DTC, or for maintaining, supervising or reviewing any records of DTC relating to those debt securities.
 
Payments in respect of the principal of, premium, if any, and interest on any debt securities registered in the name of a Global Debt Security Holder on the applicable record date will be payable by the trustee to or at the direction of such Global Debt Security Holder in its capacity as the registered holder under the indenture. Under the terms of the indenture, we and the trustee may treat the persons in whose names any debt securities, including the Global Debt Securities, are registered as the owners thereof for the purpose of receiving such payments and for any and all other purposes whatsoever. Consequently, neither we nor the trustee has or will have any responsibility or liability for the payment of such amounts to beneficial owners of the debt securities (including principal, premium, if any, and interest). We believe, however, that it is currently the policy of DTC to immediately credit the accounts of the relevant Participants with such payments, in amounts proportionate to their respective beneficial interests in the relevant security as shown on the records of DTC. Payments by Participants and Indirect Participants to the beneficial owners of the debt securities will be governed by standing instructions and customary practice and will be the responsibility of Participants or Indirect Participants.
 
Subject to certain conditions, any person having a beneficial interest in the Global Debt Securities may, upon request to the trustee and confirmation of that beneficial interest by the Depositary or its Participants or Indirect Participants, exchange such beneficial interest for debt securities in definitive form (“Certificated Debt Securities”). Upon any such issuance, the trustee is required to register these debt securities in the name of and cause the same to be delivered to, such person or persons (or the nominee of any thereof). These debt securities would be issued in fully registered form and be subject to any transfer restrictions and other procedures applicable to beneficial interests in such other Global Debt Securities for as long as it remains a beneficial interest.
 
If the Depositary for the debt securities represented by a Global Debt Security is at any time unwilling or unable to continue as depositary or ceases to be a clearing agency registered under the Exchange Act, and a successor depositary registered as a clearing agency under the Exchange Act is not appointed by us within 90 days, we will issue securities in definitive form in exchange for the Global Debt Security that had been held by the Depositary. In addition, the indenture permits us at any time and in our sole discretion to decide not to have the debt securities represented by one or more Global Debt Securities. DTC has advised us that, under its current practices, it would notify its Participants of our request, but will only withdraw beneficial interest from the Global Debt Securities at the request of each Participant. We would issue definitive certificates in exchange for any such interests withdrawn. Any debt securities issued in definitive form in exchange for the Global Debt Securities will be registered in the name or names that the Depositary gives to the trustee or other relevant agent of ours or theirs. It is expected that the Depositary’s instructions will be based upon directions received by the Depositary from Participants with respect to ownership of beneficial interests in the Global Debt Security that had been held by the Depositary.
 
Neither we nor the trustee will be liable for any delay by the Global Debt Security Holder or DTC in identifying the beneficial owners of the debt securities and we and the trustee may conclusively rely on, and will be protected in relying on, instructions from the Global Debt Security Holder or DTC for all purposes.
 
Notices
 
We will give notices by mail to holders at the addresses listed in the security register.
 
Replacement of Securities
 
We will replace any mutilated security at the holder’s expense upon surrender of the security to the trustee. We will replace securities that become destroyed, stolen or lost at the holder’s expense upon delivery to the trustee of the security or evidence of the destruction, loss or theft satisfactory to us and the trustee. In the case of a destroyed, lost or stolen security, an indemnity satisfactory to the trustee and us may be required at the holder’s expense before we will issue a replacement security.
 
Governing Law
 
The indenture and the debt securities will be governed by, and construed in accordance with, the laws of the State of New York.

ITEM 15.   INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
Section 145 of the Delaware General Corporation Law, as amended, or the DGCL, gives Delaware corporations broad powers to indemnify their present and former directors and officers and those of affiliated corporations against expenses incurred in the defense of any lawsuit to which they are made parties by reason of being or having been such directors or officers, subject to specified conditions and exclusions, gives a director or officer who successfully defends an action the right to be so indemnified and authorizes the corporation to buy directors’ and officers’ liability insurance. Such indemnification is not exclusive of any other right to which those indemnified may be entitled under any bylaw, agreement, vote of stockholders or otherwise.
 
Article VII of the registrant’s By-Laws provides that the registrant (1) shall indemnify every person who is or was a director or officer of the registrant or is or was serving at the registrant’s request as a director or officer of another corporation, partnership, joint venture, trust or other enterprise and (2) shall, if the board of directors so directs, indemnify any person who is or was an employee or agent of the registrant or is or was serving at the registrant’s request as an employee or agent of another corporation, partnership, joint venture, trust or other enterprise, to the extent, in the manner and subject to compliance with the applicable standards of conduct, provided by Section 145 of the DGCL as the same (or any substitute provision therefor) may be in effect from time to time. Any such indemnification shall continue as to a person who has ceased to be a director, officer, employee or agent and shall inure to the benefit of the heirs, executors and administrators of such a person.
 
The registrant has procured insurance for the purpose of substantially covering its future potential liability for indemnification under Section 145 of the DGCL as discussed above and certain future potential liability of individual directors or officers incurred in their capacity as such which is not subject to indemnification.

Table of Contents

The registrant has entered into Indemnification Agreements with each of its directors and officers. The Indemnification Agreements provide that the registrant shall indemnify and keep indemnified the indemnitee to the fullest extent authorized by Section 145 of the DGCL as it may be in effect from time to time from and against any expenses (including expenses of investigation and preparation and reasonable fees and disbursements of legal counsel, accountants and other experts), judgments, fines and amounts paid in settlement by the indemnitee in connection with any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative, and whether or not the cause of action, suit or proceeding incurred before or after the date of the Indemnification Agreements. The Indemnification Agreements further provide for advancement of amounts to cover expenses incurred by the indemnitee in defending any such action, suit or proceeding subject to an undertaking by the indemnitee to repay any expenses advanced which it is later determined he or she was not entitled to receive.
 
Article Eleven of the registrant’s Restated Certificate of Incorporation eliminates the personal liability of the registrant’s directors to the registrant or its stockholders for monetary damages for breach of fiduciary duty as a director, except (1) for any breach of the director’s duty of loyalty to the registrant or its stockholders, (2) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (3) under Section 174 of the DGCL (which addresses director liability for unlawful payment of a dividend or unlawful stock purchase or redemption) or (4) for any transaction from which the director derived an improper personal benefit.

ITEM 17.   UNDERTAKINGS.
 
(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 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 a 20%


II-2


Table of Contents

change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement;
 
(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 (i), (ii) and (iii) 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 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) That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser:
 
(A)    Each prospectus filed by the registrant pursuant to 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 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.
 
(5)    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 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.

Table of Contents

 
(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 Section 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 the 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.
 
(c)    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.
