LOS ANGELES, CALIFORNIA – March 20, 2007 – Bull (Euronext Paris: BUL.PA) and Telemac Corporation, the global leader in network-edge real-time accounting and billing technologies for the wireless industry have entered into a multi-year teaming agreement pursuant to which Bull will participate in marketing, managing and supporting implementations of Telemac Prepaid Technology® in Europe, the Middle East and Africa. This strategic partnership is expected to offer Bull’s clients access to Telemac’s innovative solution for pre-paid billing and to offer Telemac’s licensees access to Bull’s full range of integration and support capabilities.

This strategic partnership agreement is expected to significantly extend the reach and appeal of Telemac’s products and services.

As a global integrator, we are very pleased to offer our clients access to the Telemac advanced technology.”
