On June 18, 2018, the following communication was sent to the employees of EGC.

June 18, 2018

Dear Employees,

This morning we announced that EGC has entered into a definitive agreement to be acquired by an affiliate of Cox Oil. For those of you who are not familiar with Cox, they are an established, privately-owned independent oil and gas company, with a strong financial position and substantial assets in the Gulf of Mexico. This transaction has been unanimously approved by our Board of Directors as the best course of action for the company. I want to take a moment to describe what this news means for all of us at EGC.

As you know, we have been limited in our ability to develop our assets because of operational and financial constraints. Even after our bankruptcy, EGC emerged with a significant P&A liability that has hindered our cash flow and liquidity. We have explored opportunities for consolidation in the Gulf of Mexico for some time, and with Cox we believe we have found a partner that is well positioned to invest in the assets to achieve their full potential. While I am proud of what we have accomplished to date, I believe this transaction is in the best interests of EGC.

Cox has deep experience developing and producing assets in the Gulf of Mexico, Louisiana and Texas. Importantly, Cox also has a strong financial position, with greater financial flexibility to invest in the development of these assets. We are also confident that Cox shares our firm commitment to safe and responsible operations. Therefore, we believe this transaction makes sense not only for stockholders, but also for our employees.

Given this decision, we will no longer be pursuing the Orinoco Natural Resources (ONR) proposed transaction that we announced on May 10, 2018. While the proposed ONR transaction would have addressed some of the issues stemming from our P&A liability, it would have also involved multiple parties and required a subsequent capital raise to achieve the level of funds necessary to implement a proactive drilling program.

The proposed transaction is subject to approval by EGC’s stockholders, as well as regulators. It will likely take several months to secure the necessary approvals and complete the transaction. In the meantime, we will continue to operate our business as a separate entity. Please continue to work in a safe, efficient, and diligent manner – with the knowledge that both EGC’s and Cox’s leadership recognize your work is essential to our success.

I realize that you likely have questions related to this announcement, and we are committed to communicating developments related to this proposed transaction as they develop. We will also be holding a town hall meeting tomorrow to discuss this further.

On a personal note, let me take a moment to thank you for your hard work. I am proud of your tireless dedication to our business. Even when circumstances are challenging, your commitment has never wavered. For this, I am immensely grateful.

Sincerely,

/s/ Douglas E. Brooks

Douglas E. Brooks
Chief Executive Officer and President
