Digital Impact Signs Definitive Agreement to Acquire Marketleap, Leading Search Engine Marketer.

SAN MATEO, Calif. -- Acquisition Expands Digital Impact's Integrated Digital Marketing Services Offering

Digital Impact, Inc. (Nasdaq:DIGI), a leading provider of integrated digital marketing solutions for Global 2000 enterprises, today announced that it has signed a definitive agreement to acquire Marketleap, a San Francisco-based Internet marketing firm specializing in search engine marketing services for clients such as Kaiser Permanente, Primedia, SBC's SMARTpages.com and Tyco Electronics. This acquisition will enable Digital Impact to enhance its robust integrated marketing solutions by offering clients industry-leading search engine optimization, paid inclusion and pay-for-placement solutions.

Under the terms of the agreement, Digital Impact will acquire all of the outstanding equity of Marketleap for $1.5 million in cash and 1.25 million of Digital Impact's shares and options. Additional contingent consideration of up to 200,000 common shares of Digital Impact stock will become issuable at the end of Digital Impact's 2005 fiscal year if certain revenue milestones are met.

While email marketing remains the primary online medium for customer retention, search engine marketing has rapidly evolved into the fastest growing online customer acquisition channel. The combination of Digital Impact's strengths in email marketing with Marketleap's expertise in search engine marketing will offer clients true closed loop online marketing. Digital Impact will be able to assist clients in managing their customers through the entire lifecycle of awareness-consideration-purchase-loyalty through a combination of email and search marketing strategy, analytics and campaign execution.

Marketleap was founded in 1999 and has developed into a recognized leader in search engine optimization and online acquisition solutions. Marketleap combines innovative technology, intellectual capital, and key industry relationships with expert campaign management to achieve client business objectives online. Under the leadership of co-founders Noel McMichael and Paul Owen, Marketleap has experienced rapid growth and established itself as an industry thought and tools leader. Additionally, Marketleap was a founding board member of the Search Engine Marketers Professional Organization, where McMichael is Vice President.

"This is a strategic acquisition for the Company," said William Park, Chairman and CEO of Digital Impact. "It reflects our strong commitment to broadening the digital marketing services and technologies we provide for our Global 2000 clients, and to integrating customer acquisition with retention, search with email marketing. Marketleap has delivered exceptional results for its clients in the hottest area of digital marketing and we look forward to making their technologies and expertise available to our clients."

"We are extremely pleased to be joining forces with Digital Impact," said Noel McMichael, President and co-founder of Marketleap. "We know our clients are eager to expand their use of email to retain and grow their online customer relationships. We are equally eager to offer our acquisition tools and services to Digital Impact's blue chip base of clients, many of whom are expected to expand their search strategies this year."

"As someone who's worked with Marketleap since 1999 and seen their growth and professionalism, the acquisition of Marketleap by Digital Impact is a good move for both companies," said Marshall Simmonds, Director of Search for Primedia. "Marketleap has provided About.com, MotorTrend, and other Primedia divisions reliable search marketing technology and service. Marketleap's expertise in search marketing is surpassed only by their passion and customer support. I look forward to seeing the results of this partnership."

Outlook

Digital Impact expects the acquisition to result in approximately $1.5 million in additional net revenues and approximately $300,000 in EBITDA(1) for fiscal 2005, before the impact of integration and transition costs. Due to non-cash charges, related to the amortization of intangible assets and stock based compensation, the transaction is not expected to be accretive in GAAP earnings per share for fiscal 2005. The Company is maintaining its fiscal first quarter guidance, provided in April, of $10.0 to $10.5 million in revenues and a loss of $0.02 to $0.04 per share. Going into the seasonally slow summer quarter, the Company expects consolidated fiscal second quarter revenues to be in the range of $10.0 to $10.5 million. The company will be providing more definitive EPS guidance during its quarterly earnings release and conference call on July 22.

(1) EBITDA, or earnings before other income and expense, taxes, depreciation, amortization, and stock-based compensation, is a non-GAAP financial measure. The company believes that EBITDA is a useful measure of our business's operations, and can be used to supplement GAAP financial measures in evaluating company performance. At this time we are not providing a detailed reconciliation of EBITDA to GAAP net income because we have not completed the purchase price allocation which will determine the value of the intangible assets, in-process R&D and goodwill.

Digital Impact will host a conference call to discuss the acquisition at 11:00 a.m. PT today. The call is open to everyone and those wishing to participate should call 973-935-2100 or access the web cast at www.digitalimpact.com or www.fulldisclosure.com approximately 10 minutes prior.
