1. Senior Secured Credit Facilities

Overview

On July 29, 2010, in connection with the Merger, the Company entered into a credit agreement, and related security and other agreements, with Banc of America Securities LLC and UBS Securities LLC as joint lead arrangers, Banc of America Securities LLC, UBS Securities LLC, Barclays Capital Inc. and Credit Suisse Securities (USA) LLC as joint bookrunning managers, Bank of America, N.A., as administrative agent, UBS Securities LLC as syndication agent and Barclays Bank PLC and Credit Suisse Securities (USA) LLC as co-documentation agents, that provides senior secured financing of $1.490 billion, consisting of:

The Company will be the borrower under the senior secured credit facilities. The revolving credit facility will include borrowing capacity available for letters of credit and for borrowings on same-day notice, referred to as the swingline loans.

Interest Rate and Fees

Borrowings under the senior secured credit facilities will bear interest at a rate equal to, at the Company’s option, either (a) LIBOR plus an applicable margin or (b) the highest of (1) the prime commercial lending rate published by the Wall Street Journal as the “prime rate,” (2) the federal funds effective rate plus 0.50% and (3) the one-month LIBOR rate plus 1.00%, plus an applicable margin. The initial applicable margin for borrowings under the senior secured credit facilities will be 4.00% with respect to base rate borrowings and 5.00% with respect to LIBOR borrowings. The applicable margin under the revolving credit facility may be reduced subject to the Company attaining certain leverage ratios.

In addition to paying interest on outstanding principal under the senior secured credit facilities, the Company is required to pay a commitment fee of 0.75% per annum to the lenders under the revolving credit facility in respect of the unutilized commitments thereunder. The commitment fee rate may be reduced to 0.50% subject to the Company reducing its leverage to 5.00 to 1.00. The Company is also required to pay customary letter of credit fees.

Prepayments

The senior secured credit facilities will require the Company to prepay outstanding term loans, subject to certain exceptions, with:

2

The foregoing mandatory prepayments will be applied to the scheduled installments of principal of the term loan facility in direct order of maturity. Notwithstanding the foregoing, the Company will not be required to prepay loans under the term loan facility with net cash proceeds of asset sales or with excess cash flow in each case attributable to foreign subsidiaries to the extent that the repatriation of such amounts is prohibited or delayed by applicable local law or would result in material adverse tax consequences; provided that, if not previously repatriated and applied to such prepayment within 12 months, an amount equal to the affected portion of excess cash flow or asset sale proceeds will be applied to prepay the term loan facility or to other local indebtedness of restricted subsidiaries organized in the relevant jurisdiction.

The Company may voluntarily repay outstanding loans under the senior secured credit facilities at any time without premium or penalty, other than customary breakage costs with respect to LIBOR loans and other than a 1% premium in connection with certain repricing transactions consummated within the first year of the closing of the senior secured credit facilities.

Amortization

The term loan facility will amortize in equal quarterly installments in aggregate annual amounts equal to 1% of the original principal amount of the term loan facility, with the balance being payable on the date that is six and one half years after the closing of the senior secured credit facilities.

Principal amounts outstanding under the revolving credit facility are due and payable in full at maturity, five years from the date of the closing of the senior secured credit facilities.

Guarantee and Security

Pursuant to a Master Guarantee Agreement dated as of July 29, 2010, among Intermediate, the Company, substantially all U.S. subsidiary guarantors and Bank of America, N.A., as administrative agent, all obligations under the senior secured credit facilities are unconditionally guaranteed by Intermediate and each existing and subsequently acquired or organized direct or indirect wholly-owned domestic restricted subsidiary of the Company (subject to certain exceptions). Subject to certain requirements, the senior secured credit facilities will permit the Company to release subsidiary guarantors from their guarantees; provided that not more than 15% of consolidated EBITDA for the most recently ended four-quarter period is attributable to such non-guarantors on a pro forma basis.

Pursuant to a Collateral Agreement dated as of July 29, 1010, among Intermediate, the Company, substantially all U.S. subsidiary guarantors and Bank of America, N.A., as administrative agent, all obligations under the senior secured credit facilities, and the guarantees of such obligations, are secured, subject to permitted liens and other exceptions, by substantially all of the assets of the Company and each subsidiary guarantor, including but not limited to: (i) a perfected pledge of all the equity interests of the Company and each wholly-owned subsidiary of the Company directly held by the Company or a subsidiary guarantor (limited to 65% of voting stock in the case of foreign subsidiaries) and (ii) perfected security interests in and mortgages on substantially all tangible and intangible personal property and material fee-owned real property of the Company and the subsidiary guarantors (subject to certain exclusions).

2. Indenture and Senior Notes due 2018

Overview

On July 29, 2010, the Company issued $700,000,000 aggregate principal amount of 10.25% senior notes due 2018 (the “notes”) which mature on August 1, 2018, pursuant to an indenture, dated as of July 29, 2010 (the “Indenture”), among the Company, the guarantors party thereto and The Bank of New York Mellon Trust Company, N.A., as trustee.

The following is a brief description of the terms of the notes and the Indenture.

Ranking

The notes are the Company’s senior unsecured obligations and rank senior in right of payment to any future subordinated indebtedness; rank equally in right of payment with all of the Company’s existing and future senior indebtedness; are effectively subordinated in right of payment to the Company’s existing and future secured obligations, including indebtedness under the Company’s senior secured credit facilities, to the extent of the value of the assets securing such obligations; and are effectively subordinated in right of payment to all existing and future indebtedness and other liabilities of the Company’s non-guarantor subsidiaries (other than indebtedness and liabilities owed to the Company or one of the Company’s guarantor subsidiaries).

Guarantees

The notes are fully and unconditionally guaranteed on a senior unsecured basis by each of the Company’s existing and future direct or indirect wholly owned domestic subsidiaries that guarantees the Company’s obligations under its senior secured credit facilities. Such subsidiary guarantors are collectively referred to herein as the “subsidiary guarantors,” and such subsidiary guarantees are collectively referred to herein as the “subsidiary guarantees.” Each subsidiary guarantee will rank senior in right of payment to all future subordinated indebtedness of the subsidiary guarantor; rank equally in right of payment with all existing and future senior indebtedness of the subsidiary guarantor; be effectively subordinated in right of payment to all existing and future secured obligations of the subsidiary guarantors, including their guarantee of indebtedness under the Company’s senior secured credit facilities, to the extent of the value of the assets securing such indebtedness; and be effectively subordinated in right

4

of payment to all existing and future indebtedness and other liabilities, including trade payables, of any subsidiary that is not also a guarantor of the notes. Any subsidiary guarantee of the notes will be released in the event such guarantee is released under the senior secured credit facilities.

Optional Redemption

At any time prior to August 1, 2014, the Company may redeem all or a part of the notes, at a redemption price equal to 100% of the principal amount of the notes redeemed plus the greater of (1) 1.0% of the principal amount of the notes; and (2) the excess, if any, of (a) the present value at such redemption date of (i) the redemption price of the notes at August 1, 2014 (as set forth in the table appearing below), plus (ii) all required interest payments due on the notes through August 1, 2014 (excluding accrued but unpaid interest to such redemption date), computed using a discount rate equal to the applicable treasury rate as of such redemption date plus 50 basis points; over (b) the then outstanding principal amount of the notes (as of, and accrued and unpaid interest and additional interest, if any, to the date of redemption), subject to the rights of holders of notes on the relevant record date to receive interest due on the relevant interest payment date.

On and after August 1, 2014, the Company may redeem the notes, in whole or in part, at the redemption prices (expressed as percentages of the principal amount of the notes to be redeemed) set forth below, plus accrued and unpaid interest thereon and additional interest, if any, to the applicable redemption date, subject to the right of holders of notes of record on the relevant record date to receive interest due on the relevant interest payment date, if redeemed during the twelve month period beginning on August 1 of each of the years indicated below:

In addition, prior to August 1, 2013, the Company may, at its option, on one or more occasions redeem up to 35% of the aggregate principal amount of notes at a redemption price equal to 110.250% of the aggregate principal amount thereof, plus accrued and unpaid interest thereon and additional interest, if any, to the applicable redemption date, subject to the right of holders of notes of record on the relevant record date to receive interest due on the relevant interest payment date, with the net cash proceeds of one or more equity offerings; provided that at least 50% of the sum of the aggregate principal amount of notes issued under the Indenture and the original principal amount of any additional notes that are notes issued under the Indenture after the issue date remains outstanding immediately after the occurrence of each such redemption; provided further that each such redemption occurs within 90 days of the date of closing of each such equity offering.

Change of Control

Upon the occurrence of a change of control, which is defined in the Indenture, each holder of the notes has the right to require the Company to repurchase some or all of such holder’s notes at a purchase price in cash equal to 101% of the principal amount thereof, plus accrued and unpaid interest, if any, to the repurchase date.

Covenants

The Indenture contains covenants limiting the Company’s ability and the ability of its restricted subsidiaries to:

Events of Default

The Indenture also provides for events of default which, if any of them occurs, would permit or require the principal of and accrued interest on the notes to become or to be declared due and payable.

3. Registration Rights Agreement with Respect to the Notes

On July 29, 2010, the Company entered into a registration rights agreement with respect to the notes. In the registration rights agreement, the Company has agreed that it will use its commercially reasonable efforts to register with the Securities and Exchange Commission notes having substantially identical terms as the notes as part of offers to exchange freely tradable exchange notes for the notes.

The Company is required to use its commercially reasonable efforts to cause the exchange offer to be completed or, if required, to have one or more shelf registration statements declared effective, within 360 days after the issue date of the notes.

If the Company fails to meet this target (a “registration default”), the annual interest rate on the applicable series of notes will increase by 0.25%. The annual interest rate on the applicable series of notes will increase by an additional 0.25% for each subsequent 90-day period during which the registration default continues, up to a maximum additional interest rate of 1.0% per year over the applicable interest rate described above. If the registration default is corrected, the applicable interest rate on such notes will revert to the original level.

4. Registration Rights Agreement

On July 29, 2010, in connection with the consummation of the Merger, the Company entered into a Registration Rights Agreement (the “Registration Rights Agreement”) with Intermediate, Holdings, the Sponsors and certain other indirect investors in Holdings.

Pursuant to the terms of the Management Agreement, such affiliates will provide monitoring, advisory and consulting services to the Company and its subsidiaries. Pursuant to the Management Agreement, such affiliates are entitled to receive an aggregate annual

management fee of $3 million, which amount may increase in the event that the Company or any of its subsidiaries enter into any business combination with another entity that is large enough to constitute a “significant subsidiary” of the Company under Regulation S-X as promulgated by the Securities and Exchange Commission (the “SEC”). The Management Agreement also provides for the reimbursement of out-of-pocket expenses incurred by the Sponsors and their affiliates in connection with the provision of services pursuant to the Management Agreement, the making or any regulatory filings related to the ownership, directly or indirectly, of the Company’s and its subsidiaries’ equity securities and the ownership or sale of such equity securities. The Management Agreement has an initial term expiring on the eight year anniversary of the Management Agreement, provided that the term will be extended for successive one-year terms unless the Company or each affiliate of the Sponsors provides notice to the other of their desire not to automatically extend the term. In addition, pursuant to the Management Agreement, such affiliates of the Sponsors also received aggregate transaction fees of $50 million at the closing of the Merger in connection with certain services provided in connection with the Merger and related transactions. In the event of an initial public offering or certain other circumstances, including a change of control transaction and other financing, acquisition and disposition transactions, such affiliates may also receive certain additional fees in amounts to be agreed. The Management Agreement also contains customary exculpation and indemnification provisions in favor of the Sponsors and their affiliates.
