     OMAHA, NE — infoUSA Inc. (Nasdaq: IUSA) today announced that it has proposed to acquire Digital Impact, Inc. (Nasdaq: DIGI) for $2.00 per share in cash. infoUSA’s proposal has been communicated to the Digital Impact board of directors but has not yet resulted in a substantive discussion regarding the terms of a potential transaction.

     Vin Gupta, Chairman and Chief Executive Officer of infoUSA, commented, “A combination of infoUSA and Digital Impact would create a powerful leader in the fast-growing digital marketing space. I firmly believe that the critical mass that would be created by such a combination is necessary to generate respectable operating margins in a very fragmented industry. In addition, infoUSA will be able to offer an integrated suite of highest quality databases, data processing services, and digital marketing solutions to Digital Impact’s Global 2000 customer base. This transaction would enhance long-term value for the combined company by leveraging a unified technology platform to drive incremental cross-sell opportunities and greater operating margins.”
