Global Telecom & Technology Appoints Chief Financial Officer




MCLEAN, Va., January 24, 2007 – Global Telecom & Technology, Inc. (“GTT”),
(OTCBB: GTLT), a global Multi-Network Operator (MNO), today announced the
appointment of Kevin J. Welch as its Chief Financial Officer.

As CFO of GTT, Mr. Welch will oversee all global finance functions and have
direct responsibility for leading all corporate accounting, tax, treasury and
Sarbanes-Oxley compliance activities. In addition to managing the company’s
anticipated financial growth, GTT expects that Mr. Welch will play a principal role
in the company’s potential M&A activities, help develop new and value-added
services, and direct GTT’s global human resources.

The position had been previously held by David Ballarini. Mr. Ballarini had served
as CFO of Mercator Partners Acquisition Corp. which acquired Global
Internetworking and European Telecommunications & Technology in October
2006. Following the closing of that transaction, Mercator Partners Acquisition
Corp. changed its name to GTT, and Mr. Ballarini continued to serve as CFO for
GTT on an interim basis.

“We are very pleased to have Kevin join the GTT team,” said Mike Keenan,
Chief Executive Officer, GTT. “Kevin has a great deal of experience working with
fast-growing companies like GTT. His deep knowledge of global finance,
strategy, and the telecommunications industry will be invaluable to GTT. Our
plans for future growth make him the ideal person to oversee the company’s
financial operations and support our efforts to deliver value for our shareholders.”

Mr. Welch brings to GTT over 16 years of financial and operation experience,
primarily in the telecommunications industry. Mr. Welch served in various
capacities at LCI International, Inc., from 1995 until its acquisition by Qwest
Communications in June 1998. Mr. Welch worked for Qwest Communications
from 1998 until 2003, holding various positions including Vice President of
Investor Relations and Vice President, Finance and Assistant Treasurer. As
Assistant Treasurer, Mr. Welch played a significant role in the renegotiation and
restructuring of a major portion of Qwest’s public debt. Prior to joining LCI
International, Mr. Welch worked for MCI Telecommunications from 1990 until
1995.

Most recently Mr. Welch served as Meristar Hospitality Corporation’s Senior Vice
President and Treasurer from December 2004 until the company was acquired in
May 2006. At Meristar, Mr. Welch was responsible for the company’s treasury,
financial planning and analysis, and investor relations as well as managed
strategic financing activities for the company.

Prior to joining Meristar, Mr. Welch served as CFO of Landmat International, a
privately-held mobile communications applications developer.

Mr. Welch holds a Masters in Business Administration from Georgetown
University and received his Bachelor of Science from the Colorado School of
Mines.

“I am very excited to join GTT at this time of growth and opportunity,” said Mr.
Welch. “I am impressed with GTT’s global approach, market position, strong
management team and commitment to customer satisfaction. I look forward to
contributing to our anticipated growth and continued success as a Multi-Network
Operator.”

European Telecommunications & Technology Limited, Global Telecom &
Technology, Inc. (“GTT”) (OTCBB: GTLT) is a new type of service provider: a
Multi-Network Operator (“MNO”).

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
