Please replace BW5434, (MA-UNICA) iDine Rewards Network Inc. Selects Unica Corporation's Affinium for Improved Effectiveness, with the following revised release.

The corrected release reads:

IDINE REWARDS NETWORK INC. SELECTS UNICA(R) CORPORATION'S AFFINIUM(TM) FOR IMPROVED EFFECTIVENESS AND TRACKING OF MARKETING CAMPAIGNS

Leading Enterprise Marketing Management Solution to Increase Revenue, ROI and Reduce Campaign Cycle Time

Unica Corporation, a worldwide provider of Enterprise Marketing Management (EMM) solutions proven to deliver reduced marketing costs and increased ROI, today announced that iDine Rewards Network Inc. (AMEX:IRN) has selected Unica Corporation's Affinium to improve the efficiency and effectiveness of their on- and off-line marketing initiatives. iDine, one of the nation's leading providers of loyalty and rewards programs, will take advantage of Affinium's predictive modeling and segmentation capabilities to produce more targeted marketing campaigns that are more strategically implemented and expected to result in higher response rates. iDine also will use Affinium to track and measure campaign effectiveness for rapid learning and continual strategic improvement.

"Over the past few years we have experienced substantial growth in the number of iDine members and merchants participating in our programs. We expect that growth to continue both within the dining category and to expand across to other new vertical initiatives, including our new hotel rewards category that we launched on May 1st," said George S. Wiedemann, president and CEO of iDine Rewards Network Inc. "To better serve our members and merchants today and to accommodate our forecasted growth, we needed to implement an enterprise marketing management solution that is not only flexible and scalable, but also can be quickly and easily deployed. Unica's Affinium offered the features and functionality that best meet our needs in a user-friendly interface."

iDine engaged with Unica in 1Q03 and fast-tracked the installation of the system in order to design Affinium-generated campaigns. Because of the thorough training and orientation that has been provided by numerous Unica professionals, iDine is currently ahead of its implementation schedule and has several campaigns in various stages of development and implementation. These campaigns have been designed to optimize iDine's marketing strategies and to provide measurable results. Affinium is being used both on the front-end for campaign segmentation and on the back-end to analyze and measure results within the existing dining platform and across other new vertical areas of interest such as new markets, new partner opportunities and new reward categories including hotels.

Affinium will replace an older system that has become too restrictive and limiting in light of the company's significant expansion in member and merchant areas. Now, by taking advantage of Affinium's ease-of-use and rich functionality, iDine's marketing professionals will be able to increase the number of effective campaigns that they conduct via various channels, including email, direct mail, PDA downloads and messaging AVR with minimal IT involvement. In addition, iDine will be able to leverage Affinium's robust architecture to communicate the most relevant information and offers to its more than 15 million accounts and 10,000+ merchants as well as potential members. These various campaigns will primarily be aimed at new member activation, increased usage, frequency and spending. Affinium also will enable iDine to quickly identify and eliminate ineffective campaigns allowing the company to maximize its marketing dollars.

iDine will take advantage of Affinium's Universal Dynamic Interconnect(TM) (UDI) technology to seamlessly connect to and interact with multiple data sources on various platforms as well as multiple member touchpoint systems, including the call center, sales force automation, and the Web. Using UDI, iDine Rewards Network, with partners including nine airlines, numerous Fortune 500 companies and several national private loyalty programs will be able to integrate its databases with its partners allowing iDine to build a 360-degree view of their members. This will enable them to create customized, consistent messaging that is relevant and timely across all member touchpoints.

"Both acquiring new members and increasing existing member loyalty is critical to iDine's continued growth and success," said Yuchun Lee, CEO and co-founder of Unica Corporation. "Taking advantage of Affinium's unique capabilities, iDine will be able to execute more sophisticated marketing programs faster and with greater flexibility. This will enable the company to provide new and existing members with the most relevant, timely offers, helping to build loyalty and increase customer retention."
