AT&T Enters into Global Agreement with Omron

Providing integrated management of Omron's global network in Japan to support optimal IT resources allocation

San Antonio, Texas, April 25, 2007

Tokyo, Japan — AT&T Inc. (NYSE: T) announced today that AT&T had entered into a global agreement with Omron Corporation, (TSE:6645; ADR: OMRNY), a worldwide leader in automation, sensing and control technologies, to optimize the performance of Omron's global network. The agreement covers three years from April 2007.

Omron chose AT&T as a global network partner because of its excellent track record as a provider of networks between Omron's locations in the U.S., Europe and Asia Pacific and its ability to optimize the operation of a global network.

In the first stage of the agreement AT&T will integrate all of Omron's networks in various regions, including Japan, into a single VPN network provided by AT&T. This will establish a single network infrastructure that underpins all of Omron's global IT systems.

In the second stage, the two companies will consider moving internet connections, security, Internet Data Centers, operations management services, and other operations in various regions over to solutions provided by AT&T. By strengthening this relationship, Omron will be able to improve network quality and cost performance substantially, while establishing a global IT system, which is operated and managed from Japan in a unified manner.

As part of the agreement AT&T has also secured an order for consulting services concerning the performance of networks in India and Vietnam.

"We have been very impressed by AT&T's WAN at our overseas locations," said Michiyasu Takata, Director of Omron Network Applications Corporation. "We have chosen AT&T as an essential, mid-term partner for our shift to WAN-centered networks, which is part of a global overhaul of our IT architecture. In the future, we will consider expanding the scope of this partnership to include other areas, such as security and Internet data centers."

According to Norihiko Minato, President of AT&T Japan, Omron based its decision to enter the agreement on three areas, "AT&T's track record for the design, development, and operations of networks in Japan; our global networks, which are continuing to expand through strategic investments; and the support AT&T provides to many global corporations in realizing the optimal allocation of IT resources."

He added, "As Japanese businesses face many problems concerning the optimal allocation of IT resources, AT&T will continue investments in global networks and establish a Japan-led global account management system, thereby working with customers to support problem-solving."
