eFax Business to Address Both Small Business and Enterprise Needs with Blocks of eFax Numbers using Centralized Administration and Billing

---

MENLO PARK, CA (October 6, 1999) - eFax.com (NASDAQ: EFAX), the world's leading Internet provider of fax-to-email services, today announced an outsourced development and co-marketing partnership with FaxBack, Inc., a leading provider of fax server and fax-on-demand software, to offer eFax Business services to small businesses and corporate entities. This announcement stems from an increasing demand for blocks of eFax numbers that can be controlled by a single company administrator. As part of the new service anticipated for launch in Q4 '99, eFax.com will charge companies centrally for multiple eFax accounts and offer volume discounts based on numbers of users and usage.

"Businesses often have special requirements and need to manage and control their eFax accounts centrally," said Gary Kapner, vice president of sales. "This partnership allows us to build the software tools required to manage these business accounts while making it easy for businesses to update and control their eFax directories and services. As businesses are starting to find many of their employees using eFax services on a regular basis, they are frequently coming to us for company programs and volume discounts. This is the opportunity eFax Business will address."

eFax Business will provide small businesses and corporate entities with the option to purchase blocks of eFax numbers in quantities ranging from as few as five to a thousand or more. For large quantities and high usage, volume discounts will be made available. Using eFax Business, each eFax number and its destination address will be under the control of a designated company administrator. eFax Business is anticipated to be available in Q4 '99.

"For nearly a decade, we've developed business fax messaging solutions for such companies as Symantec (WinFax PRO for Networks), Intel (NET SatisFAXtion) and AT&T IP Services," said Jim Mueller, president of FaxBack, Inc. "Our new relationship with eFax.com teams together our leading fax software technologies with the clear leader in Internet fax services to provide the most comprehensive messaging solution on the Internet for businesses of all sizes. We are excited to be providing marketing and development efforts to support eFax Business users."
