Nuclear engineering leader AECL selects Bottomline's PayBase(R)to

improve finance operation

Atomic Energy of Canada Limited (AECL) has been awarded and recognized for its technological innovations and accomplishments in nuclear engineering. Incorporated in 1952, AECL is a world-class nuclear technology and engineering company providing customers with a full range of advanced nuclear products and services. Its CANDU(R) reactor was ranked one of Canada's top 10 engineering achievements. Wholly owned by the Government of Canada, AECL seeks to put technology to work in its product design and throughout its operations.

For the past five years, AECL has employed Bottomline Technologies' (Nasdaq: EPAY) payment management software, helping to streamline its payments by eliminating manual processing and enabling the organization to save nearly $300,000 in payment-related hardware and processing costs. AECL recently took steps to improve its accounts payable capability by adopting an enhanced payment system.

The new system, Bottomline's PayBase, provides AECL with a modular, scalable platform from which to generate and manage vendor payments, as well as employee travel and expense reimbursements.

"We rely on an extensive roster of vendors and trading partners, as well as 4,000 employees that work hard to ensure that we maintain our leadership in a highly competitive industry," said Doug Mills, manager of financial services for AECL. "It's imperative that we have a payment system to consistently meet partner and employee obligations, and by moving to the new platform we will have a solution that will grow with us, facilitating the transition to more cost effective, paper-free electronic payment delivery."

"The nuclear power industry by default demands strict standards to meet operating, security and environmental objectives," remarked Joe Mullen, president of Bottomline Technologies. "We are delighted that Atomic Energy of Canada Limited, a company driven by technology and innovation, has again selected Bottomline and PayBase as part of its critical financial operations."

PayBase, the payment component of Bottomline's Financial Resource Management (FRM) solution offerings, features a fully integrated suite of modules including ACH standardized electronic payments and Internet-enabled remittance delivery, LaserCheck(R) printing, fraud avoidance, electronic document archival and a centralized payments database. The system integrates within existing technology infrastructures, consolidates processing of multiple payment types from multiple bank accounts, and expands the capabilities of ERP or host accounting systems. PayBase can be licensed as a desktop, enterprise-wide or Web-based solution.
