(the “Company”), certain subsidiary guarantors and The Bank of New York Mellon Trust Company N.A., as trustee, entered into the Twenty-first and Twenty-second Supplemental Indentures, each dated as of June 12, 2013 (the “Supplemental Indentures”), to the indentures governing the Company’s 81/4% Senior Notes due 2015 (the “2015 Senior Notes”) and its 113/4% Senior Notes due 2016 (the “2016 Senior Notes”), respectively. The Supplemental Indentures eliminate or modify certain restrictive covenants and other provisions contained in the indentures governing the 2015 Senior Notes and 2016 Senior Notes. The Supplemental Indentures will not become operative until the 2015 Senior Notes and 2016 Senior Notes which have been validly tendered pursuant to the Company’s tender offer and related consent solicitation with respect thereto have been accepted for purchase and paid for by the Company in accordance with the provisions of such tender offer and consent solicitation.

The foregoing description of the Supplemental Indentures and related matters is qualified in its entirety by reference to the Twenty-first and Twenty-second Supplemental Indentures, copies of which are attached hereto as Exhibits 4.1 and 4.2, respectively, and are incorporated herein by reference.

On June 12, 2013, the Company entered into the Twenty-third Supplemental Indenture, dated as of June 12, 2013 (the “2019 Senior Notes Supplemental Indenture”), among the Company, the subsidiary guarantors thereto and The Bank of New York Mellon Trust Company N.A., as trustee, to the indenture governing its 91/8% Senior Notes due 2019 (the “2019 Senior Notes”).

The 2019 Senior Notes Supplemental Indenture will not become operative until the Company accepts the requisite consents validly delivered and not validly revoked in the Company’s consent solicitation related to the 2019 Senior Notes and pays the related fees on the payment date, which is expected to be on June 21, 2013.

The foregoing description of the Twenty-third Supplemental Indenture and related matters is qualified in its entirety by reference to the Twenty-third Supplemental Indenture, a copy of which is attached hereto as Exhibit 4.3 and is incorporated herein by reference.

Item 7.01. Regulation FD Disclosure.

On June 12, 2013, the Company issued press releases announcing that it priced its previously announced private offerings of (i) its 11.00% senior notes due 2021 in an aggregate principal amount of $325 million and (ii) its second lien senior secured floating rate notes due 2019 in an aggregate principal amount of $200 million (together, the “New Notes”). Copies of the press releases are attached hereto as Exhibits 99.1 and 99.2, respectively, and are incorporated herein by reference.

The New Notes have not been registered under the U.S. Securities Act of 1933, as amended, and may not be offered or sold in the United States absent registration or an applicable exemption from the registration requirements of the U.S. Securities Act of 1933, as amended.  This Current Report on Form 8-K does not constitute an offer to sell or the solicitation of an offer to buy the New Notes, nor shall it constitute an offer, solicitation or sale in any jurisdiction in which such offer, solicitation or sale is unlawful.

The Company is furnishing the information in this Item 7.01, including Exhibits 99.1 and 99.2, to comply with Regulation FD. Such information shall not be deemed to be “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended, or otherwise subject to the liabilities of that section, and shall not be deemed to be incorporated by reference into any of the Company’s filings under the Securities Act of 1933, as amended, or the Securities Exchange Act of 1934, as amended, whether made before or after the date hereof and regardless of any general incorporation language in such filings, except to the extent expressly set forth by specific reference in such a filing.

Item 8.01. Other Events.

Tender Offers and Consent Solicitation

On June 12, 2013, the Company issued press releases announcing (i) the results of its previously announced cash tender offers for any and all of its 71/8% Senior Subordinated Notes due 2016 (the “2016 Subordinated Notes”), the 2015 Senior Notes and the 2016 Senior Notes, along with the related consent solicitations to adopt certain amendments to the indentures governing such notes and (ii) the results of its previously announced consent solicitation to certain amendments to the indenture governing the 2019 Senior Notes.

As of 5:00 P.M., Eastern Time, on June 6, 2013 (the “Early Tender Deadline”), $310,452,000 aggregate principal amount of the 2016 Subordinated Notes were tendered (representing approximately 88.7% of the outstanding 2016 Subordinated Notes), $423,964,000 aggregate principal amount of the 2015 Senior Notes were tendered (representing approximately 96.8% of the outstanding 2015 Senior Notes) and $582,237,000 aggregate principal amount of the 2016 Senior Notes were tendered (representing approximately 98.6% of the outstanding 2016 Senior Notes).

However, the Company determined that the terms and conditions set forth in the Offer to Purchase and Consent Solicitation Statement, dated May 23, 2013 (the “Offer to Purchase and Consent Solicitation Statement”) have not been fully met. As a result, the Company has terminated its tender offer and related consent solicitation with respect to the 2016 Subordinated Notes.

The tender offers with respect to the 2015 Senior Notes and the 2016 Senior Notes will expire at 11:59 P.M., Eastern Time, on June 20, 2013, unless extended or earlier terminated by the Company (such time and date, as the same may be extended, the “Expiration Time”). Subject to the terms and conditions set forth in the Offer to Purchase and Consent Solicitation Statement, the Company intends to accept for purchase all 2015 Senior Notes and all 2016 Senior Notes validly tendered and not withdrawn prior to the Early Tender Deadline and intends to accept for purchase all 2015 Senior Notes and all 2016 Senior Notes tendered after the Early Tender Deadline and prior to the Expiration Time.

On June 12, 2013, the Company also announced the receipt of the requisite consents to enter into the 2019 Senior Notes Supplemental Indenture.

The 2019 Senior Notes Supplemental Indenture will not become operative unless and until the Company accepts the requisite consents validly delivered and not validly revoked and pays the related fees on the payment date, which is expected to be on June 21, 2013, in accordance with the provisions of the Consent Solicitation Statement, dated May 23, 2013.

The information set forth above under Item 1.01 is incorporated in this Item 8.01 by reference. Copies of the press releases are attached hereto as Exhibit 99.3 and 99.4, respectively, and are incorporated herein by reference.

This list of factors is not exhaustive, and new factors may emerge or changes to these factors may occur that would impact our business. Additional information regarding these and other factors may be contained in our filings with the SEC, especially on Forms 10-K, 10-Q and 8-K.

FORT WORTH, TEXAS (June 12, 2013) – Quicksilver Resources Inc. (“Quicksilver”) (NYSE: KWK) announced today that $310,452,000 of the principal amount of its outstanding 71/8% Senior Subordinated Notes due 2016 (the “2016 Subordinated Notes”), $582,237,000 of the principal amount of its outstanding 113/4% Senior Notes due 2016 (the “2016 Senior Notes”) and $423,964,000 of the principal amount of its outstanding 81/4% Senior Notes due 2015 (the “2015 Senior Notes,” collectively with the 2016 Subordinated Notes and 2016 Senior Notes, the “Notes”) were validly tendered pursuant to its previously announced Tender Offers and Consent Solicitations (each as defined below).

As previously announced, on May 23, 2013, Quicksilver commenced tender offers to purchase for cash any and all of its outstanding $350,000,000 aggregate principal amount of 2016 Subordinated Notes, any and all of its outstanding $590,620,000 aggregate principal amount of 2016 Senior Notes and any and all of its outstanding $438,000,000 aggregate principal amount of 2015 Senior Notes (collectively, the “Tender Offers”). In connection with the Tender Offers, Quicksilver also solicited the consents of the holders of the 2016 Subordinated Notes, the 2016 Senior Notes and the 2015 Senior Notes to adopt certain amendments to the indentures governing the Notes (the “Consent Solicitations”) described in more detail in the Offer to Purchase and Consent Solicitation Statement (defined below).

The early tender deadline relating to the Tender Offers and the Consent Solicitations occurred at 5:00 P.M., Eastern Time, on Thursday, June 6, 2013 (the “Early Tender Deadline”). Notes previously tendered and Notes that are tendered after the Early Tender Deadline may not be withdrawn or revoked, except as required by law. As of the Early Tender Deadline, Quicksilver has been advised by D.F. King & Co., Inc., as tender agent and information agent for the Tender Offers and Consent Solicitations, that the notes were validly tendered and not withdrawn and consents were delivered and not revoked, with respect to (i) $310,452,000 of the outstanding $350,000,000 aggregate principal amount of 2016 Subordinated Notes (representing approximately 88.7% of the outstanding 2016 Subordinated Notes), (ii) $582,237,000 of the outstanding $590,620,000 aggregate principal amount of 2016 Senior Notes (representing approximately 98.6% of the outstanding 2016 Senior Notes) and (iii) $423,964,000 of the outstanding $438,000,000 aggregate principal amount of 2015 Senior Notes (representing approximately 96.8% of the outstanding 2015 Senior Notes).

The Tender Offers and Consent Solicitations are subject to the terms and conditions set forth in the Offer to Purchase and Consent Solicitation Statement, dated May 23, 2013, relating thereto (the “Offer to Purchase and Consent Solicitation Statement”). In particular, the Tender Offers are subject to the satisfaction or waiver of certain conditions, including a financing condition, a consent condition and general conditions. If any conditions to the Tender Offers are not satisfied, Quicksilver is not obligated to accept for payment, purchase or pay for, and may delay the acceptance for payment of, any tendered Notes and may even terminate the Tender Offers with respect to any or all series of Notes.

Quicksilver has determined that the financing condition for the Tender Offer and related Consent Solicitation with respect to the 2016 Subordinated Notes will not be fully met. As a result, Quicksilver has terminated its Tender Offer and Consent Solicitation with respect to the 2016 Subordinated Notes. All 2016 Subordinated Notes tendered in the Tender Offer with respect thereto will be returned promptly to the respective holders thereof without any action required on the part of the holders. No consideration will be paid in the Tender Offer and Consent Solicitation with respect to the 2016 Subordinated Notes. This press release confirms the formal termination of the Tender Offer and Consent Solicitations with respect to the 2016 Subordinated Notes. Quicksilver reserves the right to make a new tender offer at a later date, but is under no obligation to do so.

The Tender Offers and Consent Solicitations with respect to the 2016 Senior Notes and the 2015 Senior Notes are scheduled to expire at 11:59 P.M. Eastern Time, on Thursday, June 20, 2013, unless extended or earlier terminated by Quicksilver (such time and date, as the same may be extended, the “Expiration Time”). Subject to the terms and conditions set forth in the Offer to Purchase and Consent Solicitation Statement, Quicksilver intends to accept for purchase all 2016 Senior Notes and all 2015 Senior Notes validly tendered and not withdrawn prior to the Early Tender Deadline and intends to accept for purchase all 2016 Senior Notes and all 2015 Senior Notes tendered after the Early Tender Deadline and prior to the Expiration Time.

As a result of receiving the requisite consents to adopt certain amendments to the indentures governing the 2016 Senior Notes and 2015 Senior Notes, on June 12, 2013, the Company, certain subsidiary guarantors and The Bank of New York Mellon Trust Company N.A., as trustee (the “Trustee”) under the indentures governing the 2016 Senior Notes and 2015 Senior Notes (the “Base Indentures”), entered into supplemental indentures (the “Supplemental Indentures”), to the Base Indentures. The Supplemental Indentures eliminate or modify certain restrictive covenants and other provisions contained in the Base Indentures. The Supplemental Indentures became effective immediately upon execution but will not become operative until the 2016 Senior Notes and 2015 Senior Notes with respect to which consents have been delivered are accepted for purchase and paid for promptly following the Expiration Time in accordance with the provisions of the Offer to Purchase and Consent Solicitation Statement.
