Waltham, Mass. - July 9, 2007 - Unica Corporation (Nasdaq: UNCA), the leader in enterprise marketing management (EMM) solutions, today announced it has entered into a definitive agreement to acquire MarketingCentral, LLC., a privately-held provider of on-demand marketing resource management (MRM) solutions.

"Unica's proposed acquisition of MarketingCentral will expand our addressable market and increase the breath of our MRM solutions while firmly positioning Unica as a leading on-demand MRM provider," said Yuchun Lee, Unica co-founder and CEO. "Affinium® Plan™, Unica's existing MRM solution, provides enterprises with the capabilities they need to meet complex marketing operations challenges. The addition of MarketingCentral will give us a proven solution for agencies, workgroups within large companies and small and medium businesses. MarketingCentral addresses the needs of these customers by offering the easiest-to-use, fastest-to-deploy, on-demand MRM platform available on the market today."

Additionally, integrating MarketingCentral with Unica's Affinium Plan will enable the company to offer a 'best of both worlds' solution - an enterprise-class MRM system connected to a secure, on-demand collaboration space for working with dispersed project teams and outside partners.

"Enabling better collaboration between dispersed groups is often the most pressing need our customers face," continued Lee. "For fast-moving marketing teams, it's truly remarkable how quickly the MarketingCentral solution can get them managing their work more effectively. The on-demand approach lets marketers get started immediately without straining internal IT resources or building a business case for a broader, enterprise-wide MRM implementation."

MarketingCentral has hundreds of customers and thousands of total users, including corporations such as New Balance Athletic Shoe, Philips Medical, Eat'n Park Hospitality Group and Rydex Investments and agencies such as Saatchi & Saatchi, Barkley and Moroch. Its MRM solution helps agencies, workgroups within large companies and small and medium businesses increase their marketing productivity while reducing costs and increasing control. In choosing an MRM solution, these customers prioritize collaborative project management, fast deployment and require limited, if any, reliance on internal IT support. MarketingCentral was also one of the first to recognize the specialized needs of agencies and, through its AgencyCentral offering, has more agency customers than any other MRM provider.

"This acquisition confirms our continued focus on sustainable growth and product innovation," said David Ryan, co-founder and chief executive officer of MarketingCentral. "Our MRM solution is the launch point for many businesses and agencies on their EMM journey. Joining Unica ensures that after taking the first step with our own product, MarketingCentral customers can seamlessly expand their EMM footprint and address marketing challenges more holistically." Bill McInerny, MarketingCentral co-founder and president, added: "We're confident that as part of Unica, the leading EMM vendor, our customers and employees alike will benefit from the latest marketing technologies, a vast distribution network and the company's fervid commitment to customer success."

Unica and MarketingCentral already share several customers who will benefit from the acquisition and the combined solution. An example is Barkley, one of the largest independent full-service agencies in the US.

"We're excited about the acquisition of MarketingCentral, which will expand our value proposition and further position us to capture market share," said Ralph Goldwasser, senior vice president and CFO, Unica. "Unica views on-demand MRM as a strategic element of our business, and in order to realize the full potential of this purchase, we intend to continue investment in the MarketingCentral platform as well as integrate Affinium Plan and MarketingCentral to create a 'best of both worlds' solution for marketers across business categories."

The acquisition is expected to close later this month.
