SAN DIEGO--(BUSINESS WIRE)--Oct. 17, 2001

Claritas Inc., the premier provider of intelligent marketing information and target marketing services, announced today the launch of MyBestB2B, the fifth Web site in its ongoing MyBest... series of sites designed to provide instant access to the most current and accurate marketing information.

The other four sites are MyBestProspects, MyBestCustomers and MyBestLists and MyBestProfiles.

The series, which is a major component of ClaritasExpress.com, debuted in July 2000 and in that time has played a key role in establishing the Claritas portal site as a leader within the market research industry.

"The MyBest... series is specifically structured so that clients can append data to their customer file, easily define a trade area, order demographic reports and pull consumer and business lists instantaneously via the Internet," said Steven Egge, Claritas senior vice president of business development and marketing.

With the addition of MyBestB2B, (presently, it can be accessed at www.claritasexpress.com) Claritas provides business market evaluation and analysis and the ability for companies to identify business prospects. "Once this analysis is completed, MyBestB2B users then have the ability to use this knowledge to create very targeted business lists directly from the site via the Claritas Business Facts database of more than 11 million business records," explained Egge.

Through a series of new modules that will be available by year-end, MyBestB2B will have the capability to:

-- Match a businesses' customer lists to the Business Facts database to obtain
additional information, check for and correct mailing information, and remove
duplicate records.

-- Once matched, conduct market penetration studies to uncover the extent to
which they have penetrated current and new markets.

-- Screen on a large variety of variables, including SIC categories, local and
national employee and sales levels, business affiliation and other company
variables.

-- Output one or more of 8 standard reports, or create a custom report using
variables of your choice.

Two more sites for specific marketing and real estate applications are in development. They are MyBestData and MyBestSegments.
