TPC GROUP

With an operating history of more than 68 years, TPC Group is proud to announce another great milestone for our Company.

In 2011, the Company announced its intentions to restart certain dehydrogenation assets at the Company’s Houston Operations upon completion of a detailed engineering study and receipt of a required air permit necessary for the planned refurbishment and upgrade to air emission controls for restart of these assets.

We are pleased to inform you that TPC Group announced its Board of Directors has approved this strategic growth project which will provide TPC with a secure and cost-effective source of isobutylene, a strategic feedstock, to enable profitable growth in our Performance Products and Fuels businesses.  We are proud of this project and the economic investment the Company will make by creating of both temporary contractor jobs during the construction phase, as well as full-time, permanent positions upon completion and start up.

A copy of the press release is also attached.  It is our commitment to be available to you should you have any questions, comments or concerns regarding this project.  In the meantime, we look forward to having an opportunity to visit with you further and provide updates throughout the construction phase.

Sincerely,

Kirk Johnson                                                                 Sara Cronin
