BANK ONE TO SEND BUSINESS ACCOUNT INFORMATION USING XPEDITE’S ENCRYPTED E-MAIL SOLUTION
Partners to develop first-of-its-kind e-mail service for business customers

CHICAGO and LOS ANGELES, April 10, 2000 -- Bank One Corporation and Xpedite a subsidiary of PTEK Holdings Inc., will test sending business customers account information via e-mail using a new encryption process that provides excellent security and does not require special software. Bank One’s automated service, Direct Delivery Business E-Mail, will allow its customers to receive and decrypt the bank’s messages on their personal computers just by using a unique pass phrase, which changes daily to provide added security.

The first bank in the U.S. to pilot the service, Bank One initially will distribute electronic data interchange (EDI) transactions. The bank will expand the service later this year to other transactional reports:

• ACH notifications
• money transfer advices
• periodic account statements
• daily positive pay reports

Through the unique pass phrase, the Bank One/Xpedite solution provides the same high level of security as PKI (public key infrastructure) encryption, which requires the distribution and use of public and private keys and special software.

"Direct Delivery Business E-Mail gives Bank One business customers information quickly" and safely," said Len Goodman, first vice president for channel management at Bank One. "Customers can receive transaction records through a secure, encrypted e-mail message instead of waiting for mailed statements. This will enable our customers to reconcile their accounts and close their books immediately after their statement accounting period ends."

How It Works

Bank One will send statements and advices to its customers via Xpedite. The statements and advices will be uniquely encrypted and addressed. Each e-mail is automatically sent to the recipient, who is required to type in the correct pass phrase in order to decrypt and read the document. To enhance the security, the pass phrase is comprised of unique variables that change daily. Additionally, the service will allow Bank One and its customers to use almost any computing format, including PDF, DOC, JPEG or TIFF.

Bank One can access the delivery status of e-mail jobs at Xpedite’s e-mail Web site MessageREACH (www.messagereach.com). Upon entering the specific job number, Bank One can view an audit trail of all distributed and undeliverable e-mails.

"We worked hand in hand with Bank One to develop a comprehensive e-mail management solution, allowing their customers to receive vital financial information both securely and quickly as soon as it is available without the need for additional software or hardware," said Max Slifer, CEO of Xpedite "By using Xpedite as an outsourced solution, Bank One will benefit from cost savings and will remain on the cutting-edge of electronic commerce, gaining increased functionality, reliability and accountability on an ongoing basis. This is truly a pioneering approach to banking."
