DG COMPLETES TENDER OFFER FOR MEDIAMIND

Acquisition Expected to Close in Coming Days

DALLAS, TX, July 25, 2011 — DG® (NASDAQ: DGIT), a leading provider of digital media services to the advertising, entertainment and broadcast industries, today announced the successful completion of the cash tender offer by DG Acquisition Corp. VII, a wholly owned subsidiary of DG, for all outstanding shares of common stock of MediaMind Technologies, Inc. (NASDAQ: MDMD) for $22.00 per share in cash, without interest.  The tender offer and withdrawal rights expired at 12:00 midnight, New York City time, on Friday, July 22, 2011.

The depositary for the tender offer has advised DG that, as of the expiration time, an aggregate of 18,168,978 MediaMind shares (including approximately 3,055,756 shares subject to guarantees of delivery), representing approximately 93.4 percent of MediaMind’s total outstanding shares as of the close of business on July 22, 2011, were validly tendered and not validly withdrawn in the tender offer.  All shares that were

validly tendered and not properly withdrawn in the tender offer have been accepted for payment.

Pursuant to the terms of the previously announced merger agreement entered into between DG and MediaMind, DG intends to complete the acquisition by effecting a “short-form” merger under Delaware law and MediaMind will become a direct, wholly-owned subsidiary of DG.  As a result of the merger, any shares of MediaMind common stock not tendered will be cancelled and (other than shares, if any, owned by MediaMind, DG, DG Acquisition Corp. VII, or their subsidiaries or affiliates, or by MediaMind’s stockholders who are entitled to and properly exercise their appraisal rights under Delaware law) converted into the right to receive $22.00 in cash, without interest, the same price that was paid in the tender offer.  The acquisition is expected to close in the coming days.  Following the merger, MediaMind’s common stock will cease to trade on NASDAQ.

Goldman Sachs & Co. and Bank of America Merrill Lynch acted as financial advisors and Latham & Watkins LLP provided legal advice to DG.
