Lightbridge Announces Definitive Agreement to Sell PrePay INS Business to VeriSign, Inc. and
Engages Investment Banker to Explore Strategic Alternatives
for Telecom Decisioning Services Business

Burlington, MA – April 25, 2005 –Lightbridge, Inc. (NASDAQ: LTBG), a leading analytics, decisioning and e-commerce company, today announced it has entered into a definitive agreement to sell its PrePay Intelligent Network Solutions (INS) business to VeriSign, Inc. (NASDAQ: VRSN) for $17.45 million in cash plus assumption of certain contractual liabilities. The acquisition is expected to close in the second quarter.

Lightbridge’s INS business develops, delivers and supports the Lightbridge PrePay IN product, a leading Intelligent Network (IN) solution for wireless operators, which delivers real-time rating for innovative voice and emerging data services.

“We believe the Lightbridge PrePay IN product is a great complement to VeriSign’s existing portfolio of intelligent infrastructure services,” said Robert Donahue, Chief Executive Officer at Lightbridge, Inc. “Although INS is a business with a robust product and significant distribution partnerships, we believe it is in the best interest of our shareholders, customers and employees to exit that business. We are pleased to be working with VeriSign and believe that this is a positive transaction for both companies.”

Lightbridge also announced today that it has engaged the investment banking firms of Needham & Company, Inc. and Gridley & Co. LLC., to advise the Company on strategic alternatives for its Telecom Decisioning Services (TDS) business. Lightbridge expects to investigate a range of possible alternatives. No assurance can be given that any transaction will result from the exploration process that Needham/Gridley has been retained to manage.

Commenting on the news, Bob Donahue, president and chief executive officer stated, “We continually look at ways to enhance shareholder value and, in doing so, we plan to consider all reasonable alternatives for the TDS business. Needham/Gridley will assist management and the Board in evaluating strategic alternatives for the TDS business that maximize the value to the Company. The sale of INS to VeriSign is an example of our commitment to execute on our strategic goals.”
