Frequently Asked Questions

1. What is the best estimate for the closing date? The transaction is expected to close in the second quarter of 2018. Completion of the transaction is subject to the approval of the Company’s stockholders, consent of a majority of the unaffiliated holders of the Company’s 7.50% Senior Secured Notes due 2022 and successful completion of an exchange of the Company’s notes for Talos notes, certain regulatory approvals and other customary conditions. Some of these conditions are not within our control and include interactions with various governmental agencies and, as such, we are unable to predict the timing of the closing with any greater certainty at this time.

2. After closing, am I eligible to receive severance payments and benefits under the Company’s Employee Severance Plan? Yes, if in general you are a regular employee of Stone who is normally scheduled to work 30 or more hours per week (other than certain executives) and you experience an “Involuntary Termination” at any time between closing and 12-months after closing. Under the Employee Severance Plan, an “Involuntary Termination” occurs if (i) your employment is terminated by Stone (or any other eligible entity designated as an “Employer” in accordance with the plan) other than for “Cause” (as defined in the plan), or (ii) if you voluntarily terminate your employment, during the 12-month period immediately following closing, because you have been asked in writing to move more than 50 miles to perform your job and you decline the relocation.

3. After closing, what severance payments and benefits are available under the Company’s Employee Severance Plan? If you are a participant in the plan and experience an “Involuntary Termination” (both, as discussed in 2 above) that occurs during the 12-month period immediately following closing, and you sign and deliver a release of claims that is not revoked within the time allowed under the release, the severance payments and benefits available under the Company’s Employee Severance Plan will include cash and employer-supplemented benefits described in more detail below:

a. A lump sum cash severance payment equal to the sum of the following:

i. (x) the dollar amount of one week’s pay based on your annual rate of base salary or annualized rate of base wages (whichever is applicable) in place immediately prior to your termination date (“Annual Pay”), multiplied by (y) the number of full years of continuous service you have had with the Company (to include the time you are employed by a Talos subsidiary); plus

ii. a dollar amount equal to one week’s pay based on your Annual Pay for each full $10,000 of Annual Pay; provided, however, that

iii. the sum of (i) and (ii) above will not be less than 12 weeks of your Annual Pay nor exceed 52 weeks of your Annual Pay.

b. A lump sum cash payment equal to 100% of your annual bonus opportunity, if any, at target, for the calendar year in which the Involuntary Termination occurs (or, if greater, your target bonus for the 2017 calendar year), pro-rated by the number of days that have elapsed from January 1 of that calendar year until the date of the Involuntary Termination.

c. Up to six (6) months of continued group health plan coverage for you and your eligible dependents at active employee rates, if following your termination date you timely elect to continue participating in some or all of the group health plans sponsored by the Company or Talos.

d. Certain outplacement services and any earned but unpaid portion of your Annual Pay as of the date of the Involuntary Termination.

4. Will my base salary or annual bonus opportunity change after the closing? For so long as you remain an employee during the 12-month period immediately following the closing, your annual base salary or base wage rate will be no less favorable than your annual base salary or base wage rate as in effect immediately prior to the closing. In addition, for such period, you will be provided with incentive compensation opportunities that are no less favorable than the incentive compensation opportunities provided to similarly situated employees of Talos. Subject to these two limitations, your salary and annual bonus opportunity may change after closing.

5. Will my health, welfare, retirement and other employee benefits change after the closing? For so long as you remain an employee during the period between closing and June 30, 2018, you will be provided with a package of employee benefits (excluding certain specified benefits) that is no less favorable in the aggregate, to the package of employee benefits made available to you immediately prior to the closing.

6. What will happen to my health and welfare benefits after June 30, 2018? The attached is a summary of some of the Talos health and welfare benefits. As further details regarding Talos’ health and welfare benefits are determined, they will be shared with you.

7. Will my medical deductible start over in the new benefit plan? No, any medical expenses that went to your deductible under the Stone plan will be honored and continue to count toward your deductible under the Talos plan.

8. After closing, how will my 401(k) change? After closing, and no later than July 1, 2018, it is anticipated that the Stone 401(k) plan and the Talos 401(k) plan will be combined into a single 401(k) plan at Fidelity, although the precise timing and details of the combined 401(k) plan are still not fully determined. Between closing and when the Stone 401(k) plan and the Talos 401(k) plan are combined, and provided you remain employed, you will have the option to continue to contribute to the Stone 401(k) plan at Fidelity; however, any such contributions will not be eligible for matching contributions. Beginning July 1, 2018, you will qualify for Talos’s 401(k) matching program – 50% of the employee contribution up to 12% of your income. That match is made with each payroll.

9. Will my Stone earned time off, or ETO, change under Talos’s personal time off, or PTO, policy? The Talos PTO policy is based on industry experience as follows. If you have more total ETO under Stone’s policy than the Talos PTO policy allows, Talos will honor that for 2018. Beginning in 2019, the Talos policy will apply, which PTO policy is as follows:

Industry Experience	Days of PTO
0-4		15 days (3 weeks)
5-9		20 days (4 weeks)
10+		25 days (5 weeks)

10. Am I an employee of Stone or Talos? Until the closing date, you will remain an employee of Stone Energy. After the closing date, you will be an employee of a subsidiary of Talos.

If the non-technical language in this communication and the technical, legal language of a plan document conflict, the plan document always governs.
