Atos Origin Upgrades Alaska Communications Systems' mySAP(R) ERP 2005 SYSTEM

HOUSTON, TX -- (MARKET WIRE) -- November 15, 2006 -- Atos Origin, a leading international information technology (IT) services company, has completed a technical upgrade of the SAP system for Alaska Communications Systems (ACS) Group, Inc. (NASDAQ: ALSK). Under the contract, Atos Origin is also providing ACS, the leading integrated communications provider in Alaska, with ongoing system maintenance.

Atos Origin upgraded the ACS SAP 4.6b system to mySAP ERP (enterprise resource planning) 2005 (ECC 6.0). The eight-week upgrade followed the SAP Upgrade Roadmap, which includes the Blueprint, Realization, Final Preparation, and Go-live phases.

The transition to the new platform has been managed with the absolute minimum downtime and no unnecessary disruption to business. It represents one of the first upgrades of an SAP telecom customer to mySAP ERP 2005 since the software was generally released at the end of May.

"We are extremely excited to continue serving Alaska Communications Systems and fulfilling its SAP installation and support needs," said Angie Goodwin, vice president ERP services for Atos Origin North America. "The decision by ACS to again choose Atos Origin as its service provider clearly reflects the significant value that we bring to our clients across North America."

Powered by the NetWeaver® platform, mySAP ERP is a comprehensive software solution featuring leading analytics, financials, human capital management, operations and corporate services functionality. It provides ACS with a complete, reliable and flexible solution to improve internal processes, reporting, internal traceability, supply chain management and project management.

"We selected Atos Origin because of the wealth of previous experience that it is able to draw upon," said David Wilson, senior vice president and chief financial officer of ACS. "Their team understands the importance of migrating current functionality and customized features, especially those around FCC compliance, while enabling future functionality to support our business. Atos Origin is straightforward, easy to work with and conscientious -- we experienced that the first time we worked with them and are having the same positive experience this time."

In addition to the upgrade, ACS has signed an outsourcing agreement with Atos Origin. As part of the expanded relationship, Atos Origin is transitioning SAP support for ACS to the Atos Origin Application Value Management service delivered from its office in Toronto. Atos Origin will also provide Basis support from its Dallas location.

Earlier this year, Atos Origin was recognized by SAP for outstanding partnership, winning the SAP Pinnacle Award 2006 in the Global Hosting category. Atos Origin has 25 years of experience with SAP solutions and is an SAP global services partner, an SAP global hosting partner, a member of the SAP NetWeaver Partnership Initiative, a certified Powered by SAP NetWeaver solutions partner, and a leading member of the ESA Adoption program.
