Covenants of the Company

(i) Change of Control Offer

If a Change of Control Triggering Event (as defined below) occurs, unless the Company has exercised its option to redeem the Notes in accordance with Section 1.1(g) above, the Company shall be required to make an offer (a “Change of Control Offer”) to each Holder of the Notes to repurchase all or any part (equal to $2,000 or integral multiples of $1,000 in excess thereof) of that Holder’s Notes on the terms set forth in the Notes. In a Change of Control Offer, the Company shall be required to offer payment in cash equal to 101% of the aggregate principal amount of Notes repurchased, plus accrued and unpaid interest, if any, on the Notes repurchased to, but not including, the date of repurchase (a “Change of Control Payment”). Within 30 days following any Change of Control Triggering Event or, at the Company’s option, prior to any Change of Control (as defined below), but after public announcement of the transaction that constitutes or may constitute the Change of Control, a notice shall be mailed to Holders of the Notes describing the transaction that constitutes or may constitute the Change of Control Triggering Event and offering to repurchase such Notes on the date specified in the applicable notice, which date shall be no earlier than 30 days and no later than 60 days from the date such notice is mailed (a “Change of Control Payment Date”). The notice shall, if mailed prior to the date of consummation of the Change of Control, state that the Change of Control Offer is conditioned on the Change of Control Triggering Event occurring on or prior to the applicable Change of Control Payment Date.

On each Change of Control Payment Date, the Company shall, to the extent lawful:

(A) accept for payment all Notes or portions of Notes properly tendered pursuant to the applicable Change of Control Offer;

(B) deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all Notes or portions of Notes properly tendered; and

(C) deliver or cause to be delivered to the Trustee the Notes properly accepted together with an Officers’ Certificate stating the aggregate principal amount of Notes or portions of Notes being repurchased.

The Company shall not be required to make a Change of Control Offer upon the occurrence of a Change of Control Triggering Event if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for an offer made by the Company and the third party purchases all Notes properly tendered and not withdrawn under its offer. In addition, the Company shall not repurchase any Notes if there has occurred and is continuing on the Change of Control Payment Date an Event of Default, other than a default in the payment of the Change of Control Payment upon a Change of Control Triggering Event.

The Company shall comply with the requirements of Rule 14e-1 under the Exchange Act, and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control Triggering Event. To the extent that the provisions of any such securities laws or regulations conflict with the Change of Control Offer provisions of the Notes, the Company shall comply with those securities laws and regulations and shall not be deemed to have breached its obligations under the Change of Control Offer provisions herein by virtue of any such conflict.

(ii) Limitations on Liens

The Company will not at any time create, incur, assume or guarantee, and will not cause, suffer or permit a Restricted Subsidiary (as defined below) to create, incur, assume or guarantee, any Secured Debt (as defined below) without making effective provision (and the Company covenants that in such case it will make or cause to be made effective provision) whereby the Securities then outstanding and any other indebtedness of or guaranteed by the Company or such Restricted Subsidiary then entitled thereto, subject to applicable priorities of payment, shall be secured by the Security Interest (as defined below) or guaranty securing such Secured Debt equally and ratably with (or, at the Company’s option, prior to) any and all other obligations and indebtedness thereby secured, so long as any such Secured Debt remains outstanding, provided, however, that the foregoing covenants shall not be applicable to the following:

(A) (1) Any Security Interest upon any property hereafter acquired or constructed by the Company or a Restricted Subsidiary and created

contemporaneously with, or within 12 months after, such acquisition or construction to secure or provide for the payment of all or any part of the purchase price of such property or the cost of construction thereof, as the case may be; or (2) the acquisition of property subject to any Security Interest upon such property existing at the time of acquisitions thereof, whether or not the obligation secured thereby is assumed by the Company or such Restricted Subsidiary; or (3) any Security Interest existing on the property or on the outstanding shares of indebtedness of a corporation at the time such corporation shall become a Restricted Subsidiary or arising after such corporation becomes a Restricted Subsidiary pursuant to contractual commitments entered into prior to and not in contemplation of such corporation becoming a Restricted Subsidiary; or (4) any Security Interest on property of a corporation (x) existing at the time such corporation is merged into or consolidated with the Company or a Restricted Subsidiary, (y) existing at the time of a sale, lease or other disposition of the properties of a corporation or firm as an entirety or substantially as an entirety to the Company or a Restricted Subsidiary, or (z) arising after a transaction described in (x) or (y) of this clause (4) pursuant to contractual commitments entered into prior to and not in contemplation of such transaction; provided in each case that any such Security Interest does not attach to or affect property owned by the Company or a Restricted Subsidiary prior to such acquisition or construction (except the real property on which any property so constructed is physically located, in the case of any such construction) or to other property thereafter acquired or constructed other than additions to such acquired or constructed property; or

(B) Mechanics’, materialmen’s, carriers’ or other like liens, arising in the ordinary course of businesses; or

(C) Any Security Interest arising by reason of deposits with, or the giving of any form of security to, any governmental agency or any body created or approved by law or governmental regulations as a condition to the transaction of any business, or the exercise of any privilege or license; or

(D) Liens of taxes or assessments for the then current year not at the time due, or the liens of taxes or assessments already due but the validity of which is being contested in good faith and against which adequate reserves have been established; or

(E) Judgment liens, so long as the finality of such judgment is being contested in good faith and execution thereon is stayed; or

(F) Leases, and, so long as the rent secured thereby is not in default, landlords’ liens on fixtures and movable property located on premises leased in the ordinary course of business; or

(G) Security Interests arising in connection with contracts with or made at the request of the United States of America or any department or agency thereof, insofar as such Security Interests relate to property manufactured, installed or constructed by or to be supplied by, or property furnished to, the Company or a Restricted Subsidiary pursuant to, or to enable the performance of such contracts, or property the manufacture, installation, construction or acquisition of which is financed by the United States of America or any department or agency thereof pursuant to, or to enable the performance of, such contracts; or

(H) Security Interests in property of the Company or a Restricted Subsidiary in factor of the United States of America or any state thereof or any foreign government, or any department, agency or instrumentally or political subdivision of any thereof, to secure partial progress, advance or other payments pursuant to any contract or statute or to secure any indebtedness incurred for the purpose of financing all or any part of the purchase price or the cost of construction of the property subject to such Security Interests; or

(I) Any Security Interest in favor of the United States of America, or any state, country or local government, or to any agency thereof, in connection with the financing of a Principal Property (as defined below) (including without limitation, any such Principal Property designed primarily for the purpose of pollution control), and any transfers of title to any such Principal Property or Security Interest in any such Principal Property, in favor of such government or governmental agency in each case as are necessary or appropriate to permit the acquisition, construction, attachment or removal of such Principal Property; provided that such transfer of title and the lien of any such Security Interest does not apply to any other assets now or hereafter owned by the Company or any Restricted Subsidiary; or

(J) Any extension, renewal or replacement (or successive extensions, renewals or replacements) in whole or in part of any Security Interest referred to in the foregoing subparagraphs (A) through (I), inclusive, provided that the principal amount of Secured Debt secured thereby shall not exceed the principal amount outstanding at the time of such extension, renewal or replacement, and that such extension, renewal or replacement shall be limited to the property which secured the Security Interest so extended, renewed or replace and additions to such property.

Notwithstanding the foregoing provisions, the Company and any one or more Restricted Subsidiaries may issue, assume or guarantee Secured Debt which

would otherwise be subject to the foregoing restrictions in an aggregate amount which, together with all other Secured Debt of the Company and its Restricted Subsidiaries which would otherwise be subject to the foregoing restrictions (not including Secured Debt permitted to be secured under subparagraphs (A) through (I), inclusive, above) and the aggregate value of the Sale and Leaseback Transactions in existence at such time (not including Sale and Leaseback Transactions the proceeds of which have been or will be applied in accordance with subparagraph (B) of Section 1.1(q)(iii) below), does not at the time exceed 10% of Consolidated Net Tangible Assets (as defined below).

(iii) Limitations on Sale and Leaseback Transactions

The Company will not, and will not permit any Restricted Subsidiary to, engage in any Sale and Leaseback Transaction (as defined below), unless:

(A) the Company or such Restricted Subsidiary would be entitled, pursuant to the provisions of Section 1.1(q)(ii) hereof (without reference to subparagraphs (A) through (J) thereof), to incur Secured Debt equal in amount to the amount realized or to be realized upon such sale or transfer secured by a Security Interest on the property to be leased without equally and ratably securing the Securities; or

(B) the Company or a Restricted Subsidiary shall apply, within 120 days after such sale or transfer, an amount equal to the value of the property so leased to (1) the purchase or construction of properties, facilities or equipment used for operating purposes or (2) the retirement of other Funded Debt (as defined below) of the Company or of any Restricted Subsidiary (other than any Funded Debt owed to the Company or any Restricted Subsidiary); provided, however, that the amount to be applied to the retirement of Funded Debt of the Company shall be reduced by the sum of (x) the principal amount of any Securities delivered within 120 days after such sale or transfer to the Trustee for retirement and cancellation and (y) the principal amount of Funded Debt, other than Securities, voluntarily retired by the Company within 120 days after such sale or transfer. Notwithstanding the foregoing, no retirement of Funded Debt pursuant to clause (B)(2) of this Section 1.1(q)(iii) may be effected by payment at maturity or pursuant to any mandatory sinking fund payment or any mandatory prepayment provision.

The term “value” shall mean with respect to a Sale and Leaseback Transaction, as of any particular time, the amount equal to the greater of (x) the net proceeds of the sale of the property leased pursuant to such Sale and Leaseback Transaction or (y) the fair value of such property at the time of entering into such Sale and Leaseback Transaction, as determined by the Board of Directors, in either case divided first by the number of full years of such term remaining at the time of

determination, without regard to any renewal or extension options contained in the lease.

(iv) Limitations on Transfer of a Principal Property to an Unrestricted Subsidiary

The Company will not itself, and will not permit any Restricted Subsidiary to, transfer (whether by merger, consolidation or otherwise) any Principal Property to any Unrestricted Subsidiary (as defined below), unless it shall, within 120 days of the effective date of such transfer, apply an amount equal to the fair value of such property at the time of such transfer, as determined by the Board of Directors, to (A) the purchase or construction of properties, facilities or equipment used for operating purposes or (B) the retirement of other Funded Debt of the Company or of any Restricted Subsidiary (other than any Funded Debt owed to the Company or any Restricted Subsidiary); provided, however, that the amount to be applied to the retirement of Funded Debt of the Company shall be reduced by the sum of (x) the principal amount of any Securities delivered within 120 days after such sale or transfer to the Trustee for retirement and cancellation and (y) the principal amount of Funded Debt, other than Securities, voluntarily retired by the Company within 120 days after such sale or transfer. Notwithstanding the foregoing, no retirement of Funded Debt pursuant to clause (B) of this Section 1.1(q)(iv) may be effected by payment at maturity or pursuant to any mandatory sinking fund payment or any mandatory prepayment provisions.
