BMB Munai, Inc. Enters Agreement to Extend Noteholders' Redemption Rights

ALMATY, Kazakhstan, Jan. 28, 2011 /PRNewswire/ -- BMB Munai, Inc. (NYSE Amex: KAZ) today announced that in connection with its ongoing negotiations to restructure its U.S. $60,000,000 aggregate principal amount of 9.0% Convertible Senior Notes due 2012 (the "Notes"), it has entered into Supplemental Indenture No. 4 with The Bank of New York Mellon, as trustee for the holders of the Notes (the "Noteholders") extending the terms of the redemption rights available to the Noteholders.

Pursuant to the terms of the original Indenture, as amended and supplemented by Supplemental Indenture No. 1, Supplemental Indenture No. 2 and Supplemental Indenture No. 3, the Noteholders had the right to redeem the Notes between September 13, 2010 and January 31, 2011 by delivering notice on or prior to January 31, 2011. Supplemental Indenture No. 4 grants the Noteholders an additional right to require redemption of the Notes upon two days notice any time after January 31, 2011 but on or before February 28, 2011.

In exchange for the extension of the redemption right, the Company agreed to an increase in the put price associated with such a redemption from 104.88% of the principal amount together with accrued but unpaid interest as of the put exercise date to 105% of the principal amount together with accrued but unpaid interest as of the put exercise date. The Noteholders separately agreed they will not exercise any redemption right that would be effective prior to February 28, 2011, except in certain circumstances. The Noteholders also separately agreed to waive existing defaults under the Indenture until the earlier of February 28, 2011 or the date they may exercise the new redemption right.
