(b) In the Change of Control Offer, the Issuer will offer a payment in cash equal to 101% of the aggregate principal amount of the Notes, plus accrued and unpaid interest, if any, on the Notes to the date of purchase (the “Change of Control Payment”), subject to the rights of Holders on the relevant record date to receive interest due on the relevant

EXHIBIT 10.2 -4- Interest Payment Date. Within 30 days following any Change of Control, the Issuer will deliver a notice to each Holder (with a copy to the Trustee) describing the transaction or transactions that constitute the Change of Control and offering to repurchase Notes on the date (the “Change of Control Payment Date”) specified in the notice, which date will be no earlier than 30 days and no later than 60 days from the date such notice is given, pursuant to the procedures required by this Indenture and described in such notice. The Issuer will 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 Offer. To the extent that the provisions of any securities laws or regulations conflict with this Section 4.09, the Issuer will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Section 4.09 by virtue of such compliance. (c) On the Change of Control Payment Date, the Issuer will, to the extent lawful: (1) accept for payment all Notes or portions of Notes properly tendered pursuant to the Change of Control Offer; (2) 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 (3) deliver or cause to be delivered to the Trustee the Notes properly accepted together with an Officer’s Certificate stating the aggregate principal amount of Notes or portions of Notes being purchased by the Issuer. The Paying Agent will promptly deliver to each Holder properly tendered the Change of Control Payment for the Notes, and the Trustee will promptly authenticate and deliver (or cause to be transferred by book-entry) to each Holder a new Note equal in principal amount to any unpurchased portion of the Notes surrendered, if any; provided that each new Note will be in a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof, the Issuer will publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Payment Date. (d) (i) Upon the occurrence of a Qualifying Acquisition, the Issuer will be required to make an offer (a “Qualifying Acquisition Offer”) to each Holder to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of that Holder’s Notes at a purchase price in cash equal to 101% of the aggregate principal amount of such Notes repurchased, plus accrued and unpaid interest, if any, on such Notes repurchased to the date of repurchase (the “Qualifying Acquisition Payment”), subject to the rights of such Holder on the relevant record date to receive interest due on the relevant Interest Payment Date, by delivering a notice to each Holder (with a copy to the Trustee), within 90 days following the occurrence of such Qualifying Acquisition, describing the transaction or transactions that constitute such Qualifying Acquisition and offering to repurchase the Notes on the date of repurchase specified in the notice (the

EXHIBIT 10.2 -5- “Qualifying Acquisition Payment Date,” which payment date shall be no earlier than 30 days and no later than 60 days from the date such notice is given); provided, however, that no such notice or offer will be required to the extent the Issuer, on or prior to the 90th day following the occurrence of such Qualifying Acquisition, delivers a notice to each Holder (with a copy to the Trustee) that the interest rate applicable to the Notes will be permanently increased from 6.625% per annum to 7.625% per annum, effective as of such 90th day (it being understood that, upon such increase in the interest rate, the Issuer shall no longer be required to make any such Qualifying Acquisition Offer). (ii) The Issuer will comply with the requirements of Rule 14e-1 under the Exchange Act and any other applicable securities laws and regulations to the extent those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Qualifying Acquisition Offer (if any). To the extent that the provisions of any securities laws or regulations conflict with this Section 4.09, the Issuer will comply with any applicable securities laws and regulations and will not be deemed to have breached its obligations under this Indenture by virtue of such compliance. (iii) To the extent the Issuer makes a Qualifying Acquisition Offer pursuant to this Section 4.09, on the Qualifying Acquisition Payment Date, the Issuer will, to the extent lawful: (1) accept for payment all Notes or portions of Notes properly tendered pursuant to the Qualifying Acquisition Offer; (2) deposit with the Paying Agent an amount equal to the Qualifying Acquisition Payment in respect of all Notes or portions of Notes properly tendered; and (3) deliver or cause to be delivered to the Trustee the Notes properly accepted together with an Officer’s Certificate stating the aggregate principal amount of Notes or portions of Notes being purchased by the Issuer. The Paying Agent will promptly cause to be delivered to each Holder properly tendered the Qualifying Acquisition Payment for such Notes, and the Trustee (or its authenticating agent) will, upon receipt of an Authentication Order, promptly authenticate and deliver (or cause to be transferred by book-entry) to each Holder a new Note equal in principal amount to any unpurchased portion of the Notes surrendered, if any. The Issuer will publicly announce the results of the Qualifying Acquisition Offer on or as soon as practicable after the Qualifying Acquisition Payment Date. (e) The provisions described above that require the Issuer to make a Change of Control Offer following a Change of Control, or to make a Qualifying Acquisition Offer following a Qualifying Acquisition (to the extent required under this Section 4.09(d)(i)), will be applicable whether or not any other provisions of this Indenture are applicable. Except as described above with respect to a Change of Control or a Qualifying Acquisition Offer, this Indenture does not contain provisions that permit the Holders to

EXHIBIT 10.2 -6- require that the Issuer repurchase or redeem the Notes in the event of a takeover, recapitalization or similar transaction. (f) The Issuer will not be required to make a Change of Control Offer upon a Change of Control, or to make a Qualifying Acquisition Offer following a Qualifying Acquisition (to the extent required under this Section 4.09(d)(i)), if: (1) a third party makes the Change of Control Offer or the Qualifying Acquisition Offer, as the case may be, in the manner, at the times and otherwise in compliance with the requirements set forth in this Indenture applicable to a Change of Control Offer or a Qualifying Acquisition Offer, as the case may be, made by the Issuer and purchases all Notes properly tendered and not withdrawn under the Change of Control Offer or the Qualifying Acquisition Offer, as the case may be; or (2) notice of redemption has been given pursuant to the Indenture as described under Section 3.07, unless and until there is a default in payment of the applicable redemption price. A Change of Control Offer may be made in advance of a Change of Control, with the obligation to pay and the timing of payment conditioned upon the occurrence of a Change of Control, if a definitive agreement to effect a Change of Control is in place at the time the Change of Control Offer is made, and a Qualifying Acquisition Offer may be made in advance of a Qualifying Acquisition, conditional upon the consummation of such Qualifying Acquisition, if a definitive agreement is in place for the Qualifying Acquisition at the time the Qualifying Acquisition Offer is made. (g) If holders of not less than 90% in aggregate principal amount of the outstanding Notes properly tender such Notes pursuant to the Change of Control Offer, and the Issuer, or any third party making a Change of Control Offer, in lieu of the Issuer as described above, purchases all of the Notes properly tendered by such Holders, the Issuer or such third party will have the right, upon notice given not more than 60 days following such purchase pursuant to the Change of Control Offer, described above (and not less than 15 days prior to the date fixed for redemption), to redeem all notes that remain outstanding following such purchase at a price in cash equal to 101% of the aggregate principal amount of Notes to be redeemed plus accrued and unpaid interest, if any, to the redemption date. (h) The provisions under this Section 4.09 may be waived or modified with the consent of the Holders of a majority in principal amount of the Notes.” ARTICLE II. NEW GUARANTORS SECTION 2.1.
