Proposed Waivers

The Proposed Waivers set forth in the Consent Solicitation Statement are not being amended in this Supplement and shall remain as set forth therein.

Additional Proposed Amendments to Section 4.07 (Restricted Payments) of the Indenture

The Consent Solicitation and related Consent Letter are hereby amended and supplemented to include the following additional proposed amendments, and the term “Proposed Amendments,” as defined in the Consent Solicitation Statement, is hereby amended to include the following additional proposed amendments:

Reduction in Restricted Payment Capacity Based on Consolidated Net Income

Clause (3) of Section 4.07(a) of the Indenture currently permits the Company and its Restricted Subsidiaries, subject to certain other conditions and adjustments, to make Restricted Payments in an aggregate amount not to exceed 50% of the cumulative Consolidated Net Income (or if cumulative Consolidated Net Income shall be a loss, minus 100% of such loss) of the Company and the Restricted Subsidiaries during the period (treating such period as a single accounting period) beginning on January 1, 2011 and ending on the last day of the most recent fiscal quarter of the Company ending immediately prior to the date of the making of such Restricted Payment for which internal financial statements are available, plus certain additional amounts since the Issue Date of the Notes (such date being April 14, 2011).

At the request and expense of Parent pursuant to the Merger Agreement, the Company is hereby seeking Consents from Holders to amend clause (3) of Section 4.07(a) of the Indenture to provide that, for purposes of determining the Restricted Payment capacity under such clause (3) immediately after the effective time of the Post-Effective Merger, the cumulative Consolidated Net Income of the Company and the Restricted Subsidiaries under paragraph (A) of such clause (3) shall be determined beginning on the effective date of the consummation of the Post-Effective Merger (and not on January 1, 2011), and the adjustments set forth in paragraphs (B) through (E) of such clause (3) applied to determine the Restricted Payment capacity under such clause (3), shall be determined with reference to the Merger Date (as defined below) (and not the Issue Date). This Proposed Amendment has the effect

2

of reducing the existing balance of the Restricted Payment capacity under such clause (3) to zero effective immediately after the effective time of the Post-Effective Merger. This Proposed Amendment only will become operative, if at all, immediately after the effective time of the Post-Effective Merger, but not before such effective time and not if the Planned Merger is consummated.

Reduction in General Restricted Payment Basket

Paragraph (15) under Section 4.07(b) of the Indenture currently permits the Company, subject to certain other conditions, to make Restricted Payments not to exceed $150 million in the aggregate made on or after the Issue Date; provided no Default or Event of Default then exists or would result therefrom.

At the request and expense of Parent pursuant to the Merger Agreement, the Company is hereby seeking Consents from Holders to amend paragraph (15) under Section 4.07(b) of the Indenture to reduce the capacity to make Restricted Payments thereunder from $150 million to $75 million in the aggregate made on or after the effective date of the consummation of the Post-Effective Merger; provided no Default or Event of Default then exists or would result therefrom. This Proposed Amendment only will become operative, if at all, immediately after the effective time of the Post-Effective Merger, but not before such effective time and not if the Planned Merger is consummated.

Operative Time of Amendments to Section 4.07 Relating to Payment Restrictions (Clarification)

As further described in the Consent Solicitation Statement, the Company, at the request and expense of Parent pursuant to the Merger Agreement, is seeking Consents from Holders to amend Section 4.07 of the Indenture to permit, effective only during the transitory period from the effective time of the Alternative Merger until the effective time of the Post-Effective Merger and the execution and delivery of the Assumption and Guarantee, the Company and its Restricted Subsidiaries to (i) pay dividends or make any other distribution on their respective shares of Capital Stock, (ii) make loans or advances to or pay any Indebtedness or other obligations owed to Parent or to any restricted subsidiary of Parent, and (iii) transfer any of their respective property or assets to Parent or any restricted subsidiary of Parent, so that Section 4.07 of the Indenture would not be deemed an impermissible “Payment Restriction” (as defined in the Parent Indentures) under each of the Parent Indentures during such transitory period.

The Consent Solicitation Statement (including the discussion under “Purposes and Effects of the Consent Solicitation – Purposes and Effects of Proposed Waivers and Amendments – Proposed Amendments – Section 4.07 (Restricted Payments) Amendments”) and the Consent Letter are hereby supplemented, at the request and expense of Parent pursuant to the Merger Agreement, to clarify that the Proposed Amendments described in the immediately preceding paragraph shall not be operative until the effective time of the Alternative Merger and shall cease to be operative upon the effective time of the Post-Effective Merger and the execution and delivery of the Assumption and Guarantee. An amended and restated form of Supplemental Indenture incorporating the foregoing amendment, and the other amendments described in this Supplement, is attached as Appendix I hereto.

Calculation of Certain Permitted Indebtedness

As described in the Consent Solicitation Statement, clause (3) of the Permitted Indebtedness definition under Section 4.09(b) of the Indenture provides that the aggregate principal amount of Indebtedness Incurred by the Company or any Restricted Subsidiary pursuant to the Bank Credit Agreement or other Credit Facilities shall not exceed the greater of (i) $1.8 billion and (ii) 3.50x Consolidated EBITDA of the Company and its Restricted Subsidiaries for the twelve month period ended at the end of the most recent fiscal quarter for which financial statements are available (including pro forma adjustments to Consolidated EBITDA set forth in the definition of “Consolidated Coverage Ratio”), to be reduced dollar-for-dollar by the aggregate amount of all Net Cash Proceeds of Asset Sales applied by an Obligor to repay Indebtedness under the Credit Facilities pursuant to Section 4.10 (Asset Sales) of the Indenture.

At the request and expense of Parent pursuant to the Merger Agreement, the Company is seeking Consents in the Consent Solicitation Statement to amend clause (3) of Section 4.09(b) of the Indenture to provide that to the

3

extent that the Net Cash Proceeds of any Asset Sale completed to satisfy regulatory requirements in respect of either Merger or the Post-Effective Merger are used to repay Indebtedness under the Credit Facilities, such repayment shall reduce dollar-for-dollar the $1.8 billion amount (subclause (i) of clause (3)) only but not the 3.50x Consolidated EBITDA amount (subclause (ii) of clause (3)), in determining the amount of Permitted Indebtedness under the Bank Credit Agreement or other Credit Facilities permitted by clause (3) of Section 4.09(b) of the Indenture. Notwithstanding the foregoing, pro forma adjustments to Consolidated EBITDA set forth in the definition of “Consolidated Coverage Ratio” resulting from any such Asset Sales on or prior to any Determination Date shall be included in any calculation of Consolidated EBITDA pursuant to subclause (ii) of such clause (3). The form of Supplemental Indenture has been further amended to include the foregoing clarification.

DESCRIPTION OF THE ADDITIONAL AND REVISED PROPOSED AMENDMENTS

Set forth below are the additional provisions of the Indenture that would be amended by the additional and revised Proposed Amendments described in this Supplement.

The following is qualified in its entirety by reference to the form of the Supplemental Indenture. An amended and restated form of the Supplemental Indenture (which may be modified or supplemented prior to the execution thereof in a manner that would not require additional Consents under the Indenture) to implement the Proposed Waivers and Amendments contemplated by the Consent Solicitation Statement, as amended and supplemented by this Supplement, is attached hereto as Annex I. Capitalized terms not otherwise defined in the Consent Solicitation Statement or this Supplement shall, unless the context otherwise requires, have the meanings ascribed to them in the Indenture. As presented below, where applicable, new text is indicated in bold underline text and deleted text is indicated by a strikethrough (new text / deletion).

Proposed Amendments – Definitions

Section 1.01 of the Indenture is amended to add the following additional definition:

““Merger Date” means the effective date of the consummation of the Post-Effective Merger.”

Proposed Amendments – Additional Proposed Amendments to Section 4.07 (Restricted Payments)

(a) Clause (3) of Section 4.07(a) of the Indenture is amended as follows:

“(3) the aggregate amount of Restricted Payments (the amount expended for such purposes, if other than in cash, being the fair market value of such property as determined in the good faith reasonable judgment of the Company) exceeds or would exceed the sum, without duplication, of:

(A) 50% of the cumulative Consolidated Net Income (or if cumulative Consolidated Net Income shall be a loss, minus 100% of such loss) of the Company and the Restricted Subsidiaries during the period (treating such period as a single accounting period) beginning on January 1, 2011 the Merger Date and ending on the last day of the most recent fiscal quarter of the Company ending immediately prior to the date of the making of such Restricted Payment for which internal financial statements are available, plus

(B) 100% of the fair market value of the aggregate net proceeds received by the Company from any Person (other than from a Subsidiary of the Company) from the issuance and sale of Qualified Capital Stock of the Company or the amount by which Indebtedness of the Company or any Restricted Subsidiary is reduced by the conversion or exchange of debt securities or Disqualified Capital Stock into or for Qualified Capital Stock of the Company (to the extent that proceeds of the issuance of such Qualified Capital Stock would have been includable in this clause if such Qualified Capital Stock had been initially issued for cash) subsequent to the Issue Date Merger Date and on or prior to the date of the making of such Restricted Payment (excluding any Qualified Capital Stock of the Company the purchase price of which has been financed directly or indirectly using funds (i) borrowed from the Company or any Restricted Subsidiary, unless and until and to the extent such borrowing is repaid, or (ii) contributed, extended, guaranteed or advanced by the Company or

4

any Restricted Subsidiary (including, without limitation, in respect of any employee stock ownership or benefit plan)); provided that such aggregate net proceeds are limited to cash, Cash Equivalents and other Productive Assets, plus

(C) 100% of the aggregate cash received by the Company subsequent to the Issue Date Merger Date and on or prior to the date of the making of such Restricted Payment upon the exercise of options or warrants (whether issued prior to or after the Issue Date Merger Date) to purchase Qualified Capital Stock of the Company, plus

(D) to the extent that any Restricted Investment that was made after the Issue Date Merger Date is sold for cash or Cash Equivalents or otherwise liquidated or repaid for cash or Cash Equivalents, or any dividends, distributions, interest payments, principal repayments or returns of capital are received by the Company or any Restricted Subsidiary in respect of any Restricted Investment, the proceeds of such sale, liquidation, repayment, dividend, distribution, principal repayment or return of capital, in each such case (i) reduced by the amount of any Amount Limitation Restoration (as defined below) for such Restricted Investment and (ii) valued at the cash or fair market value of Cash Equivalents received with respect to such Restricted Investment (less the cost of disposition, if any), and to the extent that any Restricted Investment consisting of a guarantee or other contingent obligation that was made after the Issue Date Merger Date is terminated or cancelled, the excess, if any, of (x) the amount by which such Restricted Investment reduced the sum otherwise available for making Restricted Payments under this Section 4.07(a), over (y) the aggregate amount of payments made (including costs incurred) in respect of such guarantee or other contingent obligation, plus

(E) to the extent that any Person becomes a Restricted Subsidiary or an Unrestricted Subsidiary is redesignated as a Restricted Subsidiary after the Issue Date Merger Date, the lesser of (i) the fair market value of the Restricted Investment of the Company and its Restricted Subsidiaries in such Person as of the date it becomes a Restricted Subsidiary or in such Unrestricted Subsidiary on the date of redesignation as a Restricted Subsidiary or (ii) the fair market value of such Restricted Investment as of the date such Restricted Investment was originally made in such Person or, in the case of the redesignation of an Unrestricted Subsidiary into a Restricted Subsidiary which Subsidiary was designated as an Unrestricted Subsidiary after the Issue Date Merger Date, the amount of the Company and its Restricted Subsidiaries’ Restricted Investment therein as determined under Section 4.18 hereof, plus the aggregate fair market value of any additional Restricted Investments (each valued as of the date made) by the Company and its Restricted Subsidiaries in such Unrestricted Subsidiary after the Issue Date Merger Date; provided that any amount so determined in (i) or (ii) shall be reduced to the extent that such Restricted Investment shall have been recouped as an Amount Limitation Restoration to the Amount Limitation of clause (5) below.”

(b) Clause (15) of Section 4.07(b) is amended as follows:

“(15) other Restricted Payments not to exceed $150 $75 million in the aggregate made on or after the Issue Date Merger Date; provided no Default or Event of Default then exists or would result therefrom;”

(c) The second and third paragraphs of Section 4.07(b) are amended as follows:

“In determining the aggregate amount of Restricted Payments made subsequent to the Issue Merger Date, Restricted Payments made pursuant to clauses 3(a)(ii), 3(b)(ii), (5), (6), (7), (8), (9), (10), (11), (12), (13), (14), (16) or (1417) of the immediately preceding paragraph shall, in each case, be excluded from such calculation; provided, that any amounts expended or liabilities incurred in respect of fees, premiums or similar payments in connection therewith shall be included in such calculation. Restricted Payments under clause (15) shall be limited to the amount of $15075 million set forth in such clause (an “Amount Limitation”). The Amount Limitation shall be permanently reduced at the time of any Restricted Payment made under such clause; provided, however, that to the extent that a Restricted Investment made under such clause is sold for cash or Cash Equivalents or otherwise liquidated or repaid for cash or Cash Equivalents, interest payments, principal repayments or returns of capital are received by the Company or any Restricted Subsidiary in respect of such Restricted Investment, valued, in each such case at the cash or marked-to-

5

market value of Cash Equivalents received with respect to such Restricted Investment (less the cost of disposition, if any), or to the extent that any Restricted Investment consisting of a guarantee or other contingent obligation that was made after the IssueMerger Date is terminated or cancelled, the excess, if any of (x) the amount by which such Restricted Investment counted toward the Amount Limitation, over (y) the aggregate amount of payments made (including costs incurred) in respect of such guarantee or other contingent obligation, then the Amount Limitation for such clause shall be increased by the amount so received by the Company or a Restricted Subsidiary or the amount of such excess of (x) over (y) (an “Amount Limitation Restoration”). In no event shall the aggregate Amount Limitation Restoration for a Restricted Investment exceed the original amount of such Restricted Investment.

With respect to clause (15) above, the Amount Limitation under such clause shall also be increased when any Person becomes a Restricted Subsidiary or an Unrestricted Subsidiary is redesignated as a Restricted Subsidiary (each such increase also referred to as an “Amount Limitation Restoration”) by the lesser of (i) the fair market value of the Restricted Investment made under clause (15) above in such Person as of the date it becomes a Restricted Subsidiary or in such Unrestricted Subsidiary as of the date of redesignation, as the case may be, or (ii) the fair market value of such Restricted Investment as of the date such Restricted Investment was originally made in such Person or, in the case of the redesignation of an Unrestricted Subsidiary into a Restricted Subsidiary which Subsidiary was designated as an Unrestricted Subsidiary after the IssueMerger Date, the amount of the Company’s Restricted Investment therein as determined under Section 4.18 hereof, plus the aggregate fair market value of any additional Investments (each valued as of the date made) made under clause (15) above in such Unrestricted Subsidiary after the IssueMerger Date.”

Each of the additional Proposed Amendments to Section 4.07 (Restricted Payments) described above will become operative, if at all, immediately after the effective time of the Post-Effective Merger, but not before such effective time and not if the Planned Merger is consummated.

Proposed Amendments – Amendments to Section 4.09 (Incurrence of Indebtedness and Issuance of Preferred Stock).

Section 4.09(b) paragraph (3) of the Indenture is amended as follows (with the addition of the last sentence at the end of paragraph (3) to incorporate the Proposed Amendment described in “Detailed Description of the Amendments –Calculation of Certain Permitted Indebtedness”):

“(3) Indebtedness Incurred by the Company or any Restricted Subsidiary pursuant to the Bank Credit Agreement or other Credit Facilities; provided that the aggregate principal amount of all such Indebtedness outstanding under this clause (3) as of any date of Incurrence (after giving pro forma effect to the application of the proceeds of such Incurrence), including all Permitted Refinancing Indebtedness Incurred to repay, redeem, extend, refinance, renew, replace, defease or refund any Indebtedness Incurred pursuant to this clause (3), shall not exceed the greater of

(i) $1.8 billion, and

(ii) 3.50x Consolidated EBITDA of the Company and its Restricted Subsidiaries for the twelve month period ended at the end of the most recent fiscal quarter for which financial statements are available (including pro forma adjustments to Consolidated EBITDA set forth in the definition of “Consolidated Coverage Ratio”),

to be reduced dollar-for-dollar by the aggregate amount of all Net Cash Proceeds of Asset Sales applied by an Obligor to repay Indebtedness under the Credit Facilities pursuant to Section 4.10 hereof; provided, however, that the aggregate amount of all Net Cash Proceeds of any Asset Sale completed to satisfy regulatory requirements in respect of the Planned Merger, the Alternative Merger or the Post-Effective Merger that are applied by an Obligor to repay Indebtedness under the Bank Credit Agreement or other Credit Facilities pursuant to Section 4.10 shall reduce dollar-for-dollar the amount set forth in the immediately preceding subclause (i) but not subclause (ii) of this clause (3) for purposes of determining the amount of Indebtedness permitted to be

6

Incurred by the Company or any Restricted Subsidiary under this clause (3). Notwithstanding the foregoing, pro forma adjustments to Consolidated EBITDA set forth in the definition of “Consolidated Coverage Ratio” resulting from any such Asset Sales on or prior to any Determination Date shall be included in any calculation of Consolidated EBITDA pursuant to subclause (ii) of this clause (3).”

The Proposed Amendments to Section 4.09 (Incurrence of Indebtedness and Issuance of Preferred Stock) described above will become operative, if at all, immediately prior to the effective time of the Alternative Merger or the Planned Merger.

DISCLOSURE REGARDING FORWARD-LOOKING STATEMENTS

Certain statements set forth or incorporated by reference in this Supplement constitute “forward-looking statements” as that term is defined under Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended.

Forward-looking statements include information concerning possible or assumed future results of operations, descriptions of our business plans and strategies and the effect of the Proposed Waivers and Amendments and the Merger (including the Planned Merger and the Alternative Merger and the Post-Effective Merger) on the Notes or on the Company or Parent after the Merger. These statements often include words such as “anticipate,” “expect,” “suggest,” “plan,” “believe,” “intend,” “estimate,” “target,” “project,” “forecast,” “should,” “could,” “would,” “may,” “will” and other similar expressions. The Company and Parent have based these forward-looking statements on their respective current expectations, plans and assumptions that they have made in light of their respective experience in the industry, as well as their perceptions of historical trends, current conditions, expected future developments and other factors they believe are appropriate under the circumstances and at the time such statements were made. Although the Company and Parent believe that these forward-looking statements are based on reasonable assumptions, you should be aware that many important factors could affect the Company’s, Parent’s and/or the combined company’s actual financial results, results of operations, the Proposed Waivers and Amendments, the Merger and the Post-Effective Merger or the Notes, and could cause actual results to differ materially from those expressed in the forward-looking statements. Such factors include, but are not limited to, those set forth under the heading “Solicitation Considerations” in the Consent Solicitation Statement, in the Annual Reports on Form 10-K of the Company and Parent for the fiscal year ended December 31, 2012 and in any report, statement or other information of the Company or Parent that is incorporated by reference in the Consent Solicitation Statement.

You should consider these areas of risk in connection with considering any forward-looking statements that may be made by the Company and Parent generally. The forward-looking statements contained or incorporated by reference in the Consent Solicitation Statement speak only as of the date of the Consent Solicitation Statement or the date of such report, statement or other information incorporated by reference in the Consent Solicitation Statement. Except as may be required by the federal securities laws, the Company and Parent undertake no obligation to revise these forward-looking statements to reflect events or circumstances arising after the date of the Consent Solicitation Statement or to reflect the occurrence of unanticipated events.

Restricted Investment was originally made in such Person or, in the case of the redesignation of an Unrestricted Subsidiary into a Restricted Subsidiary which Subsidiary was designated as an Unrestricted Subsidiary after the Merger Date, the amount of the Company and its Restricted Subsidiaries’ Restricted Investment therein as determined under Section 4.18 hereof, plus the aggregate fair market value of any additional Restricted Investments (each valued as of the date made) by the Company and its Restricted Subsidiaries in such Unrestricted Subsidiary after the Merger Date; provided that any amount so determined in (i) or (ii) shall be reduced to the extent that such Restricted Investment shall have been recouped as an Amount Limitation Restoration to the Amount Limitation of clause (5) below.

“In determining the aggregate amount of Restricted Payments made subsequent to the Merger Date, Restricted Payments made pursuant to clauses 3(a)(ii), 3(b)(ii), (5), (6), (7), (8), (9), (10), (11), (12), (13), (14), (16) or (17) of the immediately preceding paragraph shall, in each case, be excluded from such calculation; provided, that any amounts expended or liabilities incurred in respect of fees, premiums or similar payments in connection therewith shall be included in such calculation. Restricted Payments under clause (15) shall be limited to the amount of $75 million set forth in such clause (an “Amount Limitation”). The Amount Limitation shall be permanently reduced at the time of any Restricted Payment made under such clause; provided, however, that to the extent that a Restricted Investment made under such clause is sold for cash or Cash Equivalents or otherwise liquidated or repaid for cash or Cash Equivalents, interest payments, principal repayments or returns of capital are received by the Company or any Restricted Subsidiary in respect of such Restricted Investment, valued, in each such case at the cash or marked-to-market value of Cash Equivalents received with respect to such Restricted Investment (less the cost of disposition, if any), or to the extent that any Restricted Investment consisting of a guarantee or other contingent obligation that was made after the Merger Date is terminated or cancelled, the excess, if any of (x) the amount by which such Restricted Investment counted toward the Amount Limitation, over (y) the aggregate amount of payments made (including costs incurred) in respect of such guarantee or other contingent obligation, then the Amount Limitation for such clause shall be increased by the amount so received by the Company or a Restricted Subsidiary or the amount of such excess of (x) over (y) (an “Amount Limitation Restoration”). In no event shall the aggregate Amount Limitation Restoration for a Restricted Investment exceed the original amount of such Restricted Investment.

With respect to clause (15) above, the Amount Limitation under such clause shall also be increased when any Person becomes a Restricted Subsidiary or an Unrestricted Subsidiary is redesignated as a Restricted Subsidiary (each such increase also referred to as an “Amount Limitation Restoration”) by the lesser of (i) the fair market value of the Restricted Investment made under clause (15) above in such Person as of the date it becomes a Restricted Subsidiary or in such Unrestricted Subsidiary as of the date of redesignation, as the case may be, or (ii) the fair market value of such Restricted Investment as of the date such Restricted Investment was originally made in such Person or, in the case of the redesignation of an Unrestricted Subsidiary into a Restricted Subsidiary which Subsidiary was designated as an Unrestricted Subsidiary after the Merger Date, the amount of the Company’s Restricted Investment therein as determined under Section 4.18 hereof, plus the aggregate fair market value of any additional Investments (each valued as of the date made) made under clause (15) above in such Unrestricted Subsidiary after the Merger Date.”
