Subject: Important Company News

Dear Colleagues –

This morning we made the exciting announcement that we are combining with Stone Energy Corp., a publicly traded independent E&P company headquartered in Louisiana. This combination solidifies our strategy to become the premier offshore Deepwater E&P Company, while securing a platform for growth in the near term. The combination of Talos and Stone will create an even stronger company – with a large, high quality asset base and leading cost profile. The combined Company will have a significant acreage footprint in the Gulf of Mexico with over 1.2 million gross acres, of which approximately 160,000 acres is offshore Mexico, and pro forma estimated 2017 average daily production of 47 Mboe/d.

Stone is a Gulf of Mexico operator with over 100 employees in its Lafayette and New Orleans locations. Stone shares our belief that the well-being of employees is key to its success, and like Talos, is committed to a leading HSE (“Health, Safety and Environment”) track record. We are looking forward to taking this step with the Stone team.

Most importantly for you, this combination creates a premier offshore E&P Company. The pro forma portfolio will have proved reserves of 136 MMboe, as of June 30, 2017, based on SEC pricing, which are 69% oil and 74% located in the Deepwater Gulf of Mexico. We will be able to showcase our success in the Phoenix Field, including our recent Tornado II well and highlight Stone’s Pompano asset, including their recent discovery in Rampart. Of course our historic Zama discovery in Mexico will be a significant part of our long-term growth story. In summary, we will be a stronger company with more production and additional reserve development opportunities, ultimately helping Talos grow for the benefit of all of our stakeholders – including you, our valued employees.

Once this transaction is final, we will be a publically traded company on the New York Stock Exchange under the new ticker symbol “TALO,” which will offer us access to the public capital markets and enhance our growth trajectory. We will continue to be headquartered in Houston, Texas, and I will become the CEO of the combined company, with additional members of the Talos and Stone management teams serving in other key leadership roles.

That said, today’s announcement is just the first step in the process and I ask that you continue to focus on your daily responsibilities with the same sense of purpose and diligence that you always have. Until the transaction closes, which we anticipate will occur in the late first quarter or early second quarter of 2018, we will continue to operate business as usual. Additionally, because of legal restrictions related to the transaction process, I ask that you refrain from contacting any Stone employees, unless required as part of the process or in the ordinary course of business.

We are committed to open, transparent and timely communication and will update you as there is news to share. In the meantime, we will put a town hall meeting notification on the calendar so I can answer any questions you may have regarding this important milestone.

I hope you share my excitement for the opportunities that lie ahead. Thank you for your continued hard work.

Sincerely,

Tim Duncan

Chief Executive Officer
