deliver their consents and whose Notes are accepted for purchase will receive payment promptly after the Expiration Time.

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. The consents are being solicited to eliminate substantially all of the restrictive covenants and certain events of default contained in the indentures governing the Notes. Holders may not tender their Notes without delivering consents or deliver consents without tendering their Notes. Quicksilver may waive any condition and amend, extend or terminate the tender offers in its sole discretion.

For each series of Notes, noteholders may withdraw tenders and revoke consents at any time prior to the earlier of (1) 5:00 P.M., Eastern Time, on June 6, 2013 and (2) the time and date on which a supplemental indenture is entered into with respect to such series of Notes (the “Withdrawal Deadline”), which is expected to promptly follow receipt of the consents of a majority the outstanding amount of such series. Following the Withdrawal Deadline applicable to a series of Notes, tendered Notes or delivered consents for each such series may not be withdrawn or revoked.
