WATERFORD, N.Y., (June 18, 2013) – Momentive Performance Materials Inc. (“Momentive Performance

Materials” or the “Company”) today announced reaching a tentative agreement for a new, three-year contract with

the IUE-CWA, the union that represents employees at two sites in the U.S., Local 81359 and Local 81380 in

Waterford, N.Y., and Local 84707 in Willoughby, Ohio. Contract negotiations began on June 3, 2013 in

Philadelphia and lasted two weeks, ending June 17, 2013. Union leadership will bring the contract back to

represented MPM employees seeking a ratification vote later this week.

“I’m pleased with the progress made in Philadelphia, and I'm impressed with the efforts made by IUE-CWA and

MPM leadership to reach a tentative agreement, which reflects a fair and equitable solution,” said John C. Dandolph,

executive vice president and president of the Silicones and Quartz Division. “Once employees have had time to

educate themselves on the different aspects of the tentative agreement, we are hopeful that they will vote to ratify

it.”

The Company’s goal is to ensure its competitiveness so current and future generations of employees can realize the

rewards of a career at the Waterford and Willoughby plants. The IUE-CWA represents approximately 700

employees in Waterford and 60 employees in Willoughby.

“We’re pleased to have reached a tentative agreement,” said Bob Santamoor, IUE-CWA Conference Board

Chairman. “The new landscape of retirement and health care for the American workforce has changed dramatically

over the past few years. The tentative agreement provides the necessary security to allow the members of IUECWA

to transition into these new realities.”

The tentative agreement delivers employment opportunities for the region, provides a market-competitive and

comprehensive wage and benefits package and promotes a safe work environment, while managing all of the

Company’s affairs with the highest level of respect and ethical behavior.
