APTIMUS, INC. ACQUIRES HIGH VOLTAGE INTERACTIVE, A LEADING
ONLINE MARKETING FIRM SPECIALIZING IN RECRUITMENT
SOLUTIONS FOR THE EDUCATION MARKETPLACE

San Francisco, CA, August 22, 2006— Aptimus, Inc. (NASDAQ: APTM) the Point-of-Action^TM online advertising network today announced the acquisition of Sausalito, California-based High Voltage Interactive, Inc. The acquisition is a significant element of its strategy to bring a new class of transactional advertising to the world’s largest brands. High Voltage Interactive is a leading online marketing firm specializing in recruitment and enrollment solutions for the higher education marketplace.

This acquisition accelerates Aptimus’ presence in the education category and positions the combined entity as one of the top education lead providers on the Internet today. Aptimus brings extensive media reach to High Voltage through the growing base of leading Web publishers participating in the Aptimus Network. High Voltage brings deep knowledge and direct relationships in the education category and long term client relationships with all of today’s leading education marketers online.

“The acquisition of High Voltage Interactive launches Aptimus into a leadership position in our number one target category for lead generation,” said Rob Wrubel, CEO of Aptimus. “High Voltage’s total focus on the education category is a perfect match for our powerful and growing online advertising network that reaches a unique set of consumers by placing advertisements in active areas where most Web site publishers have not traditionally had advertising, including our new relationship with AOL,” added Wrubel.

High Voltage brings to Aptimus multiple years of experience working directly with top education companies, including University of Phoenix, American InterContinental University Online, Colorado Technical University Online, Kaplan University, ITT Technical Institute, and many others. High Voltage has a proven track record in performance marketing for education marketers, with direct selling experience, deep industry knowledge, and experience in converting online education leads. This expertise, combined with High Voltage’s solid existing direct relationships with schools, will enable Aptimus to significantly expand its education lead generation efforts, as well as offer new services such as school-specific hosted Web sites, unique lead follow up programs, and exclusive advertiser representation approaches.

The business will continue to operate as the High Voltage subsidiary of Aptimus, focused on the education category. Paul Epstein, the CEO of High Voltage Interactive, will continue to lead this business unit as a Senior Vice President of Aptimus and the COO of the company’s High Voltage subsidiary. Epstein is a recognized industry leader and regularly featured speaker at major education industry events such as the Career College Association’s Annual Convention, the Distance Education & Training Council Annual Conference, and the Council for Higher Education Accreditation Convention. He also

contributes frequent articles to industry publications such as “Career Education Review,” “The Greentree Gazette,” “The Link,” and more.

“Joining forces with Aptimus enables us to bring both our education clients and publishing partners a broader, richer level of service offerings,” said Epstein. “Our expertise in recruitment marketing combined with Aptimus’ technological capabilities and their extensive publisher relationships immediately makes us one of the top strategic recruitment marketers in the entire education space,” concluded Epstein.

The company anticipates the acquisition to add at least $1 million to Aptimus’ sales in the third quarter of 2006 and $2 million in fourth quarter sales. Aptimus also continues to expect organic growth of more than 10% during the third quarter. High Voltage is profitable and will add 17 employees to Aptimus. The acquisition price was $6.0 million in cash plus 200,000 shares of restricted Aptimus common stock, representing a highly accretive structure for Aptimus.

High Voltage Interactive is based in Sausalito, CA with plans to relocate to Aptimus’ San Francisco facility.
