Monument Announces Polyol Increases

September 13, 2017

Dear Monument Customer,

Effective with shipments on October 1, 2017, Monument Chemical will increase its off-list
prices of all Poly-G, Poly-Q, Poly-A and Poly-L polyols by $0.07 per pound. Poly-G®
HQEE is exempt from this increase.

The increase is being driven by the recent increase in propylene pricing which is one of our key
raw materials. Also, please be aware your purchases prior to October 1 may be limited
depending on available product inventories.

All other terms and conditions remain unchanged. If you have any questions, please
contact your local Monument Account Manager. We appreciate your continued business.
