Business Wire, June 05, 2009

OVERLAND PARK, Kan. -- Pursuant to its previously announced tender offer and consent solicitation, Compass Minerals International, Inc. (NYSE: CMP) received tenders and consents from the holders of $77,726,000, or approximately 86.75%, of its outstanding 12% Senior Subordinated Discount Notes due 2013 (the “2013 Notes”) by the expiration of the consent payment deadline, June 4, at 5:00 p.m. Eastern time (the “Consent Date”). The consents received exceeded the number needed to approve the proposed amendments to the indenture under which the 2013 Notes were issued. The terms of the tender offer and consent solicitation for the 2013 Notes are detailed in Compass Minerals’ Offer to Purchase and Consent Solicitation Statement dated May 21, 2009 (the “Offer to Purchase”).

Under the terms of the tender offer, holders who tendered on or prior to the Consent Date will receive $1,045.00 per $1,000 in principal amount of the 2013 Notes validly tendered. Holders who tender after the Consent Date will receive $1,025.00 per $1,000 in principal amount of the 2013 Notes validly tendered. The tender offer will expire at midnight, Eastern time, on June 18, 2009. Compass Minerals intends to redeem any 2013 Notes that remain outstanding after the expiration date of the tender offer.

Based on the consents received, Compass Minerals and the trustee under the indenture are expected to enter into a supplemental indenture that will, once operative, eliminate substantially all restrictive covenants and certain events of default, and reduce the required notice period with respect to redeeming the 2013 Notes pursuant to the terms of the indenture governing the 2013 Notes. The supplemental indenture will become operative today upon payment for 2013 Notes tendered on or prior to the consent date and accepted for purchase by Compass Minerals pursuant to the tender offer.
