Authorize.Net Enhances Automated Recurring Billing™

New Application Programming Interface Provides Merchants With More Flexibility for Managing Subscription-Based Transactions

LAS VEGAS, NV -- (MARKET WIRE) -- April 18, 2007 -- 2007 ETA Annual Meeting & Expo -- Authorize.Net Corp., a service of Lightbridge, Inc., (NASDAQ: LTBG), announced today the availability of an application programming interface (API) for its Automated Recurring Billing™ (ARB) service. ARB allows merchants to create "subscriptions" or recurring transactions as an additional payment option for customers. Merchants simply provide the customer's payment information, a payment schedule and the subscription duration, and ARB does the rest, generating subsequent transactions automatically.

The ARB API is a free enhancement for ARB subscribers that enables merchants integrated to Authorize.Net via the Advanced Integration Method (AIM) to create and submit recurring transactions to the payment gateway directly from a Web site or other proprietary billing application. The addition of the API significantly increases ARB's functionality, allowing merchants to:

--  Expedite the creation and management of large volume subscriptions.
--  Build subscription or installment-based payment options on their Web
    site payment form.
--  Eliminate the need to manually enter, update or cancel subscriptions
    in the Authorize.Net Merchant Interface.
    
Additionally, all ARB data is stored in Authorize.Net's highly secure data center, which complies with the Payment Card Industry (PCI) Data Security Standard, thereby providing merchants and their customers with an added level of security.

"Authorize.Net initially launched the ARB service in 2003," stated Roy Banks, president of Authorize.Net. "Since then, thousands of our merchants have used ARB to streamline their business, reduce transaction declines and potentially save money in transaction fees. With the addition of the API, we expect ARB's adoption to accelerate as more merchants take advantage of this new functionality. We're thrilled to be able to offer it to our merchants without any additional service fees."

Deepika Prakash, founder of PatternReview.com, was one of the first Authorize.Net merchants to implement the ARB API during its beta phase. "You cannot imagine how excited I was," stated Deepika. "Through the API, PatternReview.com now creates, cancels or modifies subscriptions automatically. I also created a program that sends e-mails to customers with upcoming credit card expirations which include a link to an update form all processed through the API. It's seamless."

Authorize.Net merchants already using ARB that are interested in implementing the API should contact their Web developer. A developer guide is available at http://www.authorize.net/support/ARB_guide.pdf. Merchants interested in activating ARB for their account can learn more in the Authorize.Net Merchant Toolbox at http://www.authorize.net/toolbox or can sign up in the Merchant Interface at https://secure.authorize.net.
