About GTT
Formed in October 2006, following the acquisition by Mercator Partners
Acquisition Corp. of Global Internetworking Inc and European
Telecommunications & Technology Limited, Global Telecom & Technology, Inc.
(“GTT”) (OTCBB: GTLT) is a new type of service provider: a Multi-Network
Operator (“MNO”).

As a Multi-Network Operator, GTT does not own the infrastructure upon which its
services are provided. Instead, GTT designs solutions based on its customer’s
requirements, using a combination of telecommunications networks and
technologies. Unlike traditional network centric carriers, GTT provides best-of-
breed solutions by procuring, integrating and managing components of these
various networks on its customers’ behalf. GTT has taken the inherent
advantages of the Multi-Network Operator approach to a new level through a
combination of powerful network design and pricing tools; a global service
footprint; a deep and broad set of strategic vendor relationships; and above all,
an expert team committed to delivering outstanding end-to-end customer service.

Headquartered in McLean, Virginia and with offices in London, Paris, Dusseldorf,
New Delhi, and New York, GTT provides a global service footprint covering more
than 50 countries, and it has more than 200 customers and in excess of 100
carrier partnerships around the world. For more information visit the GTT web
