CLST Holdings, Inc. Announces Amendment of Rights Plan and Plan of Dissolution

DALLAS, June 18, 2010 — CLST Holdings, Inc. (Pink Sheets: CLHI.PK) announced today that on June 17, 2010, the Board of Directors of the Company approved amendments to its stockholder rights plan (the “Rights Plan”) and its Plan of Dissolution.

The amendment to the Rights Plan allows the Board, in the event that rights under the Rights Plan are triggered and are not exercisable for any reason, including the closing of the Company’s stock transfer records on June 24, 2010 pursuant to the Company’s Plan of Dissolution, to make adjustments to liquidating distributions payable to the Company’s stockholders, as would have been appropriate had an exchange of rights been effected under the Rights Plan.

In addition, consistent with the Board’s amendment to the Rights Plan, the Board also approved an amendment to the Company’s Plan of Dissolution which allows the Board to adjust liquidating distributions to the Company’s stockholders in accordance with the Rights Plan.
