Item 1.01. Entry into a Material Definitive Agreement.

Indenture Governing CHS/Community Health Systems, Inc.’s 7.125% Senior Notes due 2020

On July 18, 2012, CHS/Community Health Systems, Inc. (the “Issuer”), a wholly-owned subsidiary of Community Health Systems, Inc. (the “Company”), issued $1,200,000,000 aggregate principal amount of its 7.125% Senior Notes due 2020 (the “2020 Notes”). The terms of the 2020 Notes are governed by an indenture, dated July 18, 2012, between the Issuer, the Company, the other guarantors party thereto and Regions Bank, as trustee (the “2020 Notes Indenture”). The 2020 Notes Indenture is being filed as Exhibit 4.1 to this Current Report on Form 8-K.

The 2020 Notes bear interest at a rate of 7.125% per year payable semi-annually in arrears on January 15 and July 15 of each year, commencing January 15, 2013.

The Issuer may redeem some or all of the 2020 Notes at any time prior to July 15, 2016 at a price equal to 100% of the principal amount of the 2020 Notes redeemed plus accrued and unpaid interest, if any, plus a “make-whole” premium, as described in the 2020 Notes Indenture. The Issuer may redeem some or all of the 2020 Notes at any time on or after July 15, 2016 at the redemption prices set forth in the 2020 Notes Indenture, plus accrued and unpaid interest, if any. In addition, the Issuer may redeem up to 35% of the aggregate principal amount of the 2020 Notes at any time prior to July 15, 2015 using the net proceeds from certain equity offerings at the redemption price set forth in the 2020 Notes Indenture, plus accrued and unpaid interest, if any.

If the Company or the Issuer experience a Change of Control (as defined in the 2020 Notes Indenture), the Issuer is required to offer to repurchase the 2020 Notes at 101% of their principal amount plus accrued and unpaid interest, if any, to the date of purchase.

The 2020 Notes Indenture provides for customary events of default which include (subject in certain cases to customary grace and cure periods), among others, nonpayment of principal or interest, breach of other agreements in the 2020 Notes Indenture, failure to pay certain other indebtedness, failure to pay certain final judgments, failure of certain guarantees to be enforceable and certain events of bankruptcy or insolvency. The 2020 Notes Indenture contains covenants that, among other things, limit the Company’s ability and the ability of its restricted subsidiaries to incur or guarantee additional indebtedness, pay dividends or make other restricted payments, make certain investments, create or incur certain liens, sell assets and subsidiary stock, transfer all or substantially all of the Company’s assets or enter into merger or consolidation transactions and enter into transactions with affiliates.

A copy of the press release announcing the completion of the offering of the 2020 Notes is being filed as Exhibit 99.1 to this Current Report on Form 8-K.

Supplemental Indenture to the Indenture Governing CHS/Community Health Systems, Inc.’s 8 ⁷/₈% Senior Notes due 2015

On July 18, 2012, the Company announced the results of the Issuer’s previously-announced tender offer and consent solicitation relating to its 8 ⁷/₈% Senior Notes due 2015 (the “2015 Notes”). As of 5:00 p.m., New York City time, on July 17, 2012, which was the consent expiration and withdrawal time specified in the Offer to Purchase and Consent Solicitation Statement (“the Statement”), holders of an aggregate principal amount of $639,705,000 of 2015 Notes tendered their notes and consented to the proposed amendments contained in the Statement. Such tenders and consents have been accepted by the Issuer and have not been withdrawn.

On July 18, 2012, the Issuer paid $1,026.00 in total consideration per $1,000 of 2015 Notes that had been accepted by the Issuer. The Issuer paid the tender and consent consideration with a portion of the proceeds from the 2020 Notes.

On July 18, 2012, pursuant to the terms of the Statement, and having received consents to the proposed amendments from holders of approximately 68.5% of the outstanding aggregate principal amount of 2015 Notes, the Issuer and U.S. Bank National Association, as trustee, entered into a supplemental indenture (the “Fifteenth Supplemental Indenture”) to the Indenture, dated July 25, 2007, governing the 2015 Notes (the “2015 Notes Indenture”). The Fifteenth Supplemental Indenture amends the 2015 Notes Indenture to eliminate substantially all of the restrictive covenants imposed upon the Issuer and the Company. The Fifteenth Supplemental Indenture is being filed as Exhibit 4.4 to this Current Report on Form 8-K.

A copy of the press release announcing the results of the tender offer and consent solicitation is being filed as Exhibit 99.2 to this Current Report on Form 8-K.
