FOR IMMEDIATE RELEASE
September 7, 2017

Tropical Storm Harvey Update #4 - 5:00 pm

THE WOODLANDS, TX - As Huntsman's manufacturing sites in the regions affected by Tropical Storm Harvey and subsequent flooding continue preparations for safe start-up in the coming days, we remain focused on assisting our employees who suffered personal property damage resulting from flood waters.

Huntsman is providing financial support to approximately 100 associates whose primary residences have been damaged by the storm's flood waters. Additionally, Huntsman entities have contributed more than $10 million to relief efforts.

We are making good progress with the restart process, with some units now in full operation. The Huntsman manufacturing sites listed below are in various stages of startup and will resume full operations as engineering and pre-startup safety checks are completed, and raw materials become available:

• Chocolate Bayou
• Conroe
• Dayton
• Port Neches

Huntsman's manufacturing sites in Freeport and Houston, Texas, have resumed normal operations.

Our manufacturing site in Pensacola, Florida, continues to operate normally as it closely monitors Hurricane Irma's path.

We are communicating directly with our customers about their orders and deliveries through our dedicated customer service and commercial contacts.

Please check our website, www.Huntsman.com, for updates.
