WATERFORD, N.Y., (July 3, 2013) – Momentive Performance Materials Inc. (“Momentive Performance Materials” or the

“Company”) today announced that IUE-CWA-represented employees at its sites in Waterford, N.Y., and Willoughby, Ohio,

voted this week to ratify the tentative agreement on a new three-year national contract. Three local unions were involved

in the contract negotiations: Local 81359 and Local 81380 in Waterford, and Local 84707 in Willoughby. Contract

negotiations began on June 3, 2013 in Philadelphia and continued until an agreement was developed and ultimately

ratified by the union membership.

“I’m pleased that our employees voted to ratify the contract. IUE-CWA and MPM leadership worked hard during

negotiations to find a balance between what is competitive in the marketplace and what meets employee needs. We

believe the result was a fair and equitable agreement, and we now know that our employees agree,” said John C.

Dandolph, executive vice president and president of the Silicones and Quartz Division. “We look forward to continuing the

productive, decades-long working relationship we have had with our represented employees and with union leadership as

we continue to serve our customers."

The Company’s goal remains ensuring its competitiveness so current and future generations of employees can realize the

rewards of a career at the Waterford and Willoughby plants. The ratified contract preserves 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.
