Provisions Applicable to All Notes

Events of Default. The Indenture provides that an Event of Default means that one or more of the following events has occurred and is continuing with respect to debt securities of a particular series:

failure for 90 days to pay interest on the debt securities of that series when due
 
failure to pay principal on the debt securities of that series when due and payable upon maturity, upon redemption or otherwise






failure to comply with any of our other agreements with respect to the debt securities or in the Indenture, which failure continues for 90 days after we receive notice from the Trustee or the holders of at least 25% of the aggregate principal amount of such series of debt securities then outstanding

occurrence of certain events relating to bankruptcy or insolvency with respect to the Company.

No Event of Default with respect to the debt securities of a particular series necessarily constitutes an Event of Default with respect to the debt securities of any other series issued under the Indenture.

If an Event of Default shall occur and be continuing with respect to any series and if it is known to the Trustee, the Trustee is required to mail to each holder of that series a notice of the Event of Default within 90 days of such default. The Trustee may withhold from holders notice of any continuing default (except a default in the payment of monies owed) if it determines that withholding notice is in their interests.

If an Event of Default with respect to a series of debt securities occurs and is continuing, the Trustee or the holders of at least 25% in aggregate principal amount of that series of debt securities then outstanding may declare the principal of that series of debt securities to be due and payable immediately. The holders of a majority in principal amount of a series of debt securities may rescind such declaration and its consequences if the rescission would not conflict with any judgment or decree and if all existing Events of Default have been cured or waived except nonpayment of principal or interest that has become due solely as a result of such acceleration.
 
Holders of debt securities may not enforce the Indenture, except as provided therein. Subject to the provisions of the Indenture relating to the duties of the Trustee, if an Event of Default occurs and is continuing the Trustee will be under no obligation to exercise any of the rights or powers under the Indenture at the request or direction of any holders of the affected series, unless, among other things, the holders shall have offered the Trustee indemnity reasonably satisfactory to it. Subject to certain limitations, the holders of a majority in aggregate principal amount of a series of debt securities then outstanding 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 holders of a majority in aggregate principal amount of the then outstanding debt securities of any series affected by a default may, in certain cases, waive such default except a default in payment of principal of, or any premium, if any, or interest on, the debt securities of that series or a call for redemption of the debt securities of that series.

Discharge and Defeasance. We may terminate all of our obligations with respect to any series of debt securities and the Indenture or any installment of principal (and premium, if any) or interest on any series of debt securities if we irrevocably deposit in trust with the Trustee money or U.S. government obligations sufficient to pay, when due, principal and interest on that series of debt securities to maturity or redemption or such installment of principal or interest, as the case may be, and if all other conditions set forth in the Indenture are met.

Merger and Consolidation. Under the Indenture, we may consolidate or merge with or transfer or lease our property and assets substantially as an entirety to another entity, provided that:

the successor entity is a corporation and assumes by supplemental indenture all of our obligations under each series of debt securities issued under the Indenture, and

after giving effect to the transaction, no default or Event of Default has occurred and is continuing.

Modification of Indenture. With the written consent of the holders of a majority in principal amount of the debt securities of each series issued under the Indenture then outstanding (with each series voting as a class), we and the Trustee may amend or supplement the Indenture or modify the rights of the holders of debt securities; provided that any such amendment that affects the terms of a series of debt securities as distinct from the other series of debt securities issued under the Indenture will require only the consent of at least a majority in aggregate principal amount of that series of debt securities then outstanding. Such majority holders may also waive compliance by us of any provision of the Indenture or any supplemental indenture, except a default in the payment of principal or interest. However, without the consent of the holder of each debt security affected, an amendment or waiver may not:

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

change the rate or the time for payment of interest,






change the principal or the fixed maturity,

waive a default in the payment of principal or interest,

make any series of debt securities payable in a different currency, or

make any change in the provisions of the Indenture concerning (a) waiver of existing defaults, (b) rights of holders of debt securities to receive payment or (c) amendments and waivers without the consent of the holder of each debt security affected.

We and the Trustee may amend or supplement the Indenture without the consent of any holder of any of series of debt securities to:

cure any ambiguity, defect or inconsistency in the Indenture or any debt securities issued thereunder,

provide for the assumption of all of our obligations under the Indenture or any debt securities issued thereunder by any corporation in connection with a merger, consolidation or transfer or lease of our property and assets substantially as an entirety,

provide for uncertificated debt securities in addition to or instead of certificated debt securities,

add to the covenants made by us for the benefit of the holders of any series of debt securities (and if such covenants are to be for the benefit of less than all series of debt securities, stating that such covenants are included solely for the benefit of such series) or to surrender any right or power conferred upon us,

add to, delete from, or revise the conditions, limitations, and restrictions on the authorized amount, terms, or purposes of issue, authentication and delivery of the debt securities, as set forth in the Indenture

secure any debt securities pursuant to the covenant described below under “-Limitation on Liens,”

provide for the issuance of and establish the form and terms and conditions of a series of debt securities or to establish the form of any certifications required to be furnished pursuant to the terms of the Indenture or any series of debt securities or to add to the rights of the holders of any series of debt securities, or

make any change that does not adversely affect the rights of any holder of debt securities in any material respect.

Limitation on Liens. The Indenture contains a covenant that if we mortgage, pledge or otherwise subject to any Lien, as defined in the Indenture (other than Permitted Liens), all or some of our property or assets, we will secure any series of debt securities under the Indenture and any of our other obligations which may then be outstanding and entitled to the benefit of a covenant similar in effect to such covenant contained in the Indenture, equally and proportionally with the indebtedness or obligations secured by such Lien, for as long as any such indebtedness or obligation is so secured. “Permitted Liens,” as defined in the First Supplemental Indenture dated August 19, 2004 between the Company and the Trustee, means any of the following Liens permitted under the Indenture:

Liens existing on the date of the initial issuance of debt securities,

Liens on any asset existing at the time such asset is acquired, if not created in contemplation of such acquisition,

Liens on any asset (a) created within 180 days after such asset is acquired, or (b) securing the cost of acquisition, construction or improvement of such asset; provided, in either case, that such Lien extends to no property or asset other than the asset so acquired, constructed or improved and property incidental thereto,

(a) Liens incidental to the conduct of our business or the ownership of our properties or otherwise incurred in the ordinary course of business which (i) do not secure debt, and (ii) do not in the aggregate materially detract from the value of our assets taken as a whole or materially impair the use thereof in the operation of our business, and (b) Liens not described in clause (a) on cash, cash equivalents or securities that secure any obligation with respect to letters of credit or surety bonds or similar arrangements, which obligation in each case does not exceed $100 million,






any Lien to secure public or statutory obligations or with any governmental agency at any time required by law in order to qualify us to conduct all or some part of our business or in order to entitle us to maintain self-insurance or to obtain the benefits of any law relating to workmen’s compensation, unemployment insurance, old age pensions or other social security, or with any court, board, commission or governmental agency as security incident to the proper conduct of any proceeding before it,

any Liens for taxes, assessments, governmental charges, levies or claims and similar charges either (a) not delinquent or (b) being contested in good faith by appropriate proceedings and as to which a reserve or other appropriate provision, if any, as shall be required in conformity with generally accepted accounting principles shall have been made,

Liens securing the performance of bids, tenders, leases, contracts, sureties, stays, appeals, indemnities, performance or similar bonds or public or statutory obligations of like nature, incurred in the ordinary course of business,

materialmen’s, mechanics, repairmen’s, employees, operators’ or other similar Liens or charges arising in the ordinary course of business incidental to the acquisition, construction, maintenance or operation of any of our assets which have not at the time been filed pursuant to law and any such Liens and charges incidental to the acquisition, construction, maintenance or operation of any of our assets, which, although filed, relate to obligations not yet due or the payment of which is being withheld as provided by law, or to obligations the validity of which is being contested in good faith by appropriate proceedings,

zoning restrictions, servitudes, easements, licenses, reservations, provisions, covenants, conditions, waivers, restrictions on the use of property or minor irregularities of title (and with respect to leasehold interests, mortgages, obligations, Liens and other encumbrances incurred, created assumed or permitted to exist and arising by, through or under or asserted by a landlord or owner of the leased property, with or without consent of the lessee) and other similar charges or encumbrances, which will not individually or in the aggregate interfere materially and adversely with our business and subsidiaries taken as a whole Liens created by or resulting from any litigation or proceeding which is currently being contested in good faith by appropriate proceedings and as to which levy and execution have been stayed and continue to be stayed or for which we are maintaining adequate reserves or other provision in conformity with generally accepted accounting principles,

any interest or title of vendor or lessor in the property subject to any lease, conditional sale agreement or other title retention agreement,

Liens in connection with the securitization or factoring of our or any of our subsidiaries’ receivables in a transaction intended to be a “true sale,” or

any Lien securing a refinancing, replacement, extension, renewal or refunding of any debt secured by a Lien permitted by any of the foregoing clauses of this definition of “Permitted Liens” to the extent secured in all material respects by the same asset or assets.

Notwithstanding the foregoing, “Permitted Liens” shall not include any Lien to secure Debt that is required to be granted on an equal and ratable basis under the “negative pledge,” or equivalent, provisions of a Debt instrument (including outstanding debt securities) as a result of the creation of a Lien that itself would constitute a “Permitted Lien.”

“Debt” of any person means, at any date, without duplication:

all obligations of such person for borrowed money,

all obligations of such person evidenced by bonds, debentures, notes or other similar instruments,

all obligations of such person as lessee which are capitalized in accordance with generally accepted accounting principles, and






all Debt secured by a Lien on any asset of such person, whether or not such Debt is otherwise an obligation of such person, all Debt of others guaranteed by such person.

The restrictions in the Indenture described above would not protect the debt holders in the event of a highly leveraged transaction in which unsecured indebtedness was incurred or in which the Liens arising in connection therewith were freely permitted under the Indenture, nor would it afford protection in the event of one or more highly leveraged transactions in which secured indebtedness was incurred by our subsidiaries.

Concerning the Trustee. The Trustee, prior to the occurrence of an Event of Default, undertakes to perform only such duties as are specifically set forth in the Indenture and, after the occurrence of an Event of Default, shall exercise the same degree of care as a prudent person would exercise in the conduct of such person’s own affairs. Subject to such provision, the Trustee may refuse to perform any duty or exercise any right or power unless it receives indemnity satisfactory to it against any loss, liability or expense. We will pay the Trustee reasonable compensation and reimburse it for reasonable expenses incurred in accordance with the Indenture.

A Trustee may resign with respect to one or more series and a successor trustee may be appointed to act with respect to such series.

U.S. Bank National Association and certain of its affiliates serve as trustee, authenticating agent, or paying agent with respect to certain other of the debt securities of the Company and its affiliates. In addition, the Company and certain of its affiliates maintain banking and other business relationships in the ordinary course of business with U.S. Bank National Association.

Additional Indebtedness. The Indenture does not limit the aggregate principal amount of senior debt securities that we may issue thereunder and provides that debt securities may be issued thereunder from time to time in one or more series.

Interest Payment Determinations. With respect to any Interest Payment Date arising while the Notes remain in book-entry form, the record date will be one business day prior to the relevant Interest Payment Date. The amount of interest payable for any period will be computed on the basis of twelve 30-day months and a 360-day year. The amount of interest payable for any period shorter than a full quarterly interest period will be computed on the basis of the number of days elapsed in a 90-day quarter of three 30-day months. If any Interest Payment Date is a legal holiday in New York, New York, the required payment will be made on the next succeeding day that is not a legal holiday as if it were made on the date such payment was due and no interest will accrue on the amount so payable for the period from and after such Interest Payment Date to such next succeeding day. “Legal holiday” means a Saturday, a Sunday or a day on which banking institutions in New York, New York are not required to be open.

Purchase and Repayment. We or our affiliates may at any time repurchase any of the outstanding Notes at any price by tender, in the open market or by private agreements, and may hold, resell or surrender such Notes to the Trustee for cancellation. The holders of the Notes do not have the right to require us to repay the Notes prior to maturity. We are not required to establish a sinking fund to retire the Notes prior to maturity.

Book-Entry Notes. All of the Notes were issued in book-entry form and are represented by global notes deposited with a nominee of The Depository Trust Company. Except in the limited circumstances described in the Indenture, certificated notes will not be issued in exchange for beneficial interests in the global notes.
