What does it mean for me? Continued opportunities for exciting and rewarding careers within a larger specialty chemicals business To the extent that Huntsman has an agreement with a labor union, that agreement will continue in effect as to the employees covered by that agreement. For all other employees, the merger agreement provides that, for at least one year following the closing, Hexion will provide compensation and employee benefits which, in the aggregate, are no less favorable than those made available to us immediately prior to the sale Your service credit, as currently recognized by Huntsman, for determining your benefits eligibility, vesting, and benefit calculation will be honored as a part of this transaction For those considering retirement, assuming that you meet the respective plan eligibility requirements, you can retire any time before or after the closing

Business as usual Continue to work safely Reassure our customers, suppliers and others with whom you have a relationship that they can expect the same integrity, quality of product, commitment to service and innovation that have defined our company Customers who source from both Huntsman and Hexion will be advised that it’s ‘business as usual’ (i.e., separate, standalone companies) until closing, and advised of any future change thereafter Continue to move forward on the plans and projects that have been approved for your division Until closing occurs, there should be no unauthorized contact between Hexion and Huntsman associates other than in the ordinary course of business
