This Employment Agreement (“Agreement”) is made and entered into as of February 3, 2012 (the
“Effective Date”), by and between Talos Energy Operating Company LLC, a Delaware limited liability company (the “Company”), and Stephen E. Heitzman (hereafter “Executive”).

 RECITALS 

WHEREAS, the Company is a wholly owned subsidiary of Talos Energy LLC, a Delaware limited liability company
(“Parent”); and 
 WHEREAS, the Executive and Parent have entered into a limited liability company agreement
of Parent, dated February 3, 2012 (the “LLC Agreement”); and 
 WHEREAS, the Executive and Parent have
entered into an Interest Award Agreement whereby the Executive shall be issued Series B Units in Parent (the “Interest Award Agreement”); and 

WHEREAS, the Company wishes to employ Executive, and Executive wishes to be employed by the Company on the terms and conditions
contained herein. 
 AGREEMENT 

NOW, THEREFORE, in consideration of the foregoing and of the respective covenants and agreements set forth below, the parties
hereto agree as follows: 
 1.    Employment. During the Employment Period (as defined in
Section 4 hereof), the Company shall employ Executive, and Executive shall serve, as Executive Vice President and Chief Operating Officer. Executive shall be appointed and shall serve as Executive Vice President and Chief
Operating Officer of the Parent. For the avoidance of doubt, Executive shall not be considered an employee of Parent. 

2.    Duties and Responsibilities of Executive. 

(a)    During the Employment Period, Executive shall devote his full time and attention to the business of the Company and
its Affiliates (as defined below), will act in the best interests of the Company and its Affiliates and will perform with due care his duties and responsibilities. Executive’s duties will include those normally incidental to the position(s) set
forth in Section 1 above of as well as whatever additional duties may be assigned to him by any senior officers or by the Board of Directors of the Company (the “Board”) from time to time. Executive
agrees to cooperate fully with any senior officers and the Board, and not to engage in any activity that interferes with the performance of Executive’s duties hereunder. During the Employment Period, Executive will not hold any type of outside
employment, engage in any type of consulting or otherwise render services to or for any other person, entity or business concern without the advance written approval of the Board; provided, that it shall not be a








 
violation of this Agreement for Executive to serve on corporate, civic, or charitable boards or committees described in Exhibit A (except for boards or committees of a
Competing Business (as defined in Section 10)) so long as such service does not interfere with the performance of Executive’s duties and responsibilities under this Agreement. 

For purposes of this Agreement, “Affiliate” means, with respect to any person, any other person directly or indirectly controlling,
controlled by, or under common control with such specified person. For purposes of the definition of “Affiliate”, “control” when used with respect to any person means the power to direct the management and policies of such
person, directly or indirectly, whether through the ownership of voting securities, by contract or otherwise, and the terms “controlling” and “controlled” have correlative meanings. For the sake of clarity, Parent and its
Subsidiaries and their affiliated entities are Affiliates of the Company. 
 (b)    Executive expressly represents and
covenants to the Company that, other than as set forth in that certain Non-Competition Agreement by and among Executive, Phoenix Exploration Company, LP, Apache Corporation and Castex Energy Inc attached
hereto as Annex 1, he is not subject or a party to any employment agreement, noncompetition covenant, nondisclosure agreement, or any other agreement, covenant, understanding, or restriction that would prohibit Executive
from executing this Agreement and fully performing his duties and responsibilities hereunder, or would in any manner, directly or indirectly, limit or affect the duties and responsibilities that may now or in the future be assigned to Executive
hereunder. 
 (c)    Executive acknowledges and agrees that Executive owes the Company a duty of loyalty as a fiduciary
of the Company, and that the obligations described in this Agreement are in addition to, and not in lieu of, the obligations Executive owes the Company under the common law. 

3.    Compensation. Any salary, bonus and other compensation payments hereunder shall be subject to all
applicable payroll and other taxes. 
 (a)    During the Employment Period the Company shall pay to Executive an
annualized base salary of $350,000 (the “Base Salary”) (less applicable taxes and withholdings) in consideration for Executive’s services under this Agreement, payable in accordance with the Company’s customary
payroll practices for executive salaries as in effect from time to time. 
 (b)    The Company shall establish, and
Executive shall be entitled to participate in, an annual performance bonus plan under which Executive will be eligible for an annual bonus (the “Annual Performance Bonus”) based on satisfaction of performance targets
established by the Board after consultation with Executive. Bonus determinations will be made by the Board within 60 calendar days of the end of each calendar year and any Annual Performance Bonus to which Executive is entitled for any calendar year
will be payable in accordance with the Company’s customary payroll practices for executive bonuses, but in no event later than March 15 of the year following the calendar year to which it relates. The Board may also award additional
bonuses or other compensation to Executive at any time in its sole and complete discretion.

 4.    Term of Employment. The initial term of this Agreement
shall be for the period beginning on the Effective Date and ending at midnight (EST) on the second anniversary thereof (the “Initial Term”). On the last day of the Initial Term and each anniversary thereafter (each such date
being referred to as a “Renewal Date”), provided that this Agreement has not been earlier terminated, this Agreement shall automatically renew and extend for a period of 12 months (each a “Renewal
Term”) unless written notice of non-renewal and termination is delivered from one party to the other at least 30 days prior to the Renewal Date. Notwithstanding any other provision of this
Agreement, this Agreement may be terminated at any time during the Initial Term or the Renewal Term (if any) in accordance with Section 6. The period from the Effective Date through the date of termination of this
Agreement, regardless of the time or reason for such termination, shall be referred to herein as the “Employment Period.”

following benefits during the Employment Period:

agrees to reimburse Executive for reasonable documented business-related expenses incurred in the performance of Executive’s duties under this Agreement in accordance with the Company’s expense reimbursement policies as in effect from time
to time. 
 (b)    Benefit Plans and Programs. To the extent permitted by applicable law and subject to
the terms and eligibility requirements of any such plan or program, Executive will be invited to participate in all benefit plans and programs, including improvements or modifications of the same, that are maintained by the Company generally for
executive employees of the Company from time to time, subject to the eligibility requirements and other terms and conditions of those plans and programs. Such benefit plans and programs shall include, but are not limited to, plans and programs
related to medical and dental coverage. The Company will not, however, by reason of this Section 5(b) be obligated either (i) to institute, maintain, or refrain from changing, amending, or discontinuing any such

“Disability” if he is eligible for benefits under a long-term disability plan maintained by the Company or, in the absence of such a plan, Executive shall be considered to have a “Disability” if due to a mental or physical
impairment, Executive is incapable, after reasonable accommodation, of performing the essential duties and services required of Executive hereunder for a period of 90 consecutive calendar days or a total of 120 calendar days during any 12 month
period. 
 7.    Severance Payments.

(ii)    If Executive or any of Executive’s dependents was participating in any group health plans
maintained by the Company or Parent as of the Termination Date (the “Company Group Health Plans”), the Company shall reimburse Executive every 30 days for the duration of the Severance Period an amount equal to the employer

employer’s plan of Executive is made available to Executive, notwithstanding that Executive or such dependent may not in fact become covered under such other employer’s plan. Executive agrees to deliver prompt notice to the Company upon
the availability of such group health coverage. In addition, Executive agrees and understands that the election of such continuation coverage and the payment of any premium due with respect to such continuation coverage will remain Executive’s
sole responsibility, and the Company will assume no obligation for payment of any such premium relating to continuation coverage.

In any case involving the occurrence or existence of the events set forth in clauses (i) or (iii) of this definition, if the Company desires to

termination, the Board may determine after such termination that Executive shall not be entitled to any severance from the Company, and any and all severance payments from the Company to Executive in any form or amount shall cease and any such
payments or reimbursements already made to Executive must be returned to the Company; provided, however, that the provisions of this Section 7(j) shall not apply to the extent that (i) the Company had knowledge of such
Cause and did not terminate the employment of the Executive within 120 days of receiving notice thereof or (ii) in the event the Company did not have knowledge of such Cause prior to the termination of the employment of the Executive or the

Company and it may also provide Employee confidential information of third parties who have supplied such information to the Company. For purposes of this Section 9, the term “Company” shall include the Company
and its Affiliates. In consideration of such Confidential Information and other valuable consideration provided hereunder, Executive agrees to comply with this Section 9.

information or materials are expressly identified as confidential or proprietary, (i) any and all non-public, confidential or proprietary information or work product of the Company or its Affiliates,
(ii) any information that gives the Company or its Affiliates a competitive business advantage or the opportunity of obtaining such advantage, (iii) any

contracts, contractual relationships, organizational or personnel matters, policies or procedures, management or compensation matters, compliance or regulatory matters, as well as any technical, seismic, industry, market or other data, studies or
research, or any forecasts, projections, valuations, derivations or other analyses, performed, generated, collected, gathered, synthesized, purchased or owned by, or otherwise in the possession of, the Company or its Affiliates. Confidential
Information also includes any non-public, confidential or proprietary information about, or belonging to, any third party that has been entrusted to the Company or its Affiliates. Notwithstanding the

(iii) to return to the Company all Confidential Information in Executive’s possession upon completion of any work for the Company requiring Executive to have such Confidential Information or upon separation from the Company for any reason.
For the avoidance of doubt, Executive specifically acknowledges and agrees that any use by Executive of such Confidential Information other than as required in connection with fulfilling his duties as Executive for the benefit of the Company will be
a material breach of this Agreement. 
 (c)    Scope. Executive understands and agrees that all
Confidential Information, in whatever medium (verbal, written, electronic or other), is subject to this Agreement whether provided directly to Executive or not, whether provided to Executive prior to the Effective Date of this Agreement or not, and
whether inadvertently disclosed to Executive or not. Confidential Information that was or is available to Executive or to which Executive had or has access will be deemed to have been provided to Executive. Executive also hereby agrees that
Confidential Information shall be deemed to include information regarding the assets of the Company, even if such information was learned by Executive prior to formation of the Company. 

(d)    Value and Security. Executive understands and agrees that all Confidential Information, and every
portion thereof, constitutes the valuable intellectual property of the Company, its Affiliates, and/or third parties, and Executive further acknowledges the importance of maintaining the security and confidentiality of the Confidential Information
and of not misusing the Confidential Information. 
 (e)    Disclosure Required By Law. If Executive is
legally required to disclose any Confidential Information, Executive shall promptly notify the Company in writing of such 

  
 11 








 
request or requirement so that the Company may seek an appropriate protective order or other relief. Executive agrees to cooperate with and not to oppose any effort by the Company to resist or
narrow such request or to seek a protective order or other appropriate remedy. In any case, Executive will (A) disclose only that portion of the Confidential Information that, according to the advice of his or her counsel, is required to be
disclosed, (B) use his best efforts to obtain assurances that such Confidential Information will be treated confidentially, and (C) promptly notify the Company in writing of the items of Confidential Information so disclosed. 

(f)    Third-Party Confidentiality Agreements. To the extent that the Company possesses any confidential
information that is subject to any confidentiality agreements with, or obligations to, third parties, Executive will comply with all such agreements or obligations in full. 

(g)    Survival. The covenants made by Executive in this Section 9 will survive
termination of this Agreement indefinitely. 
 10.    Agreement Not to Compete. 

(a)    Covenants. In consideration of the Company’s providing Confidential Information as described in
Section 9 as well as Executive’s employment hereunder in which Executive will be associated with the goodwill of the Company, and to protect the trade secrets and Confidential Information of Company disclosed or
entrusted to Executive by Company or created or developed by Employee for Company and the goodwill developed by Executive on behalf of Company, and as an express incentive for Company to enter into this Agreement, Executive agrees that, except in
the ordinary course and scope of his employment hereunder, Executive shall not, either as principal, agent, independent contractor, consultant, director, officer, employee, employer, advisor, stockholder, partner, member, joint venturer, owner or in

relating to such Restricted Prospects (or attempt to do any of the foregoing); or 
 (v)    during the
Employment Period and the twelve (12) month period following the Termination Date, directly or indirectly, recruit or otherwise solicit or induce any employee, officer, consultant, contractor, or subscriber of the Company or its controlled

(vi)    at any time use the names of the Company or its Affiliates in connection with any business that is
or would be in competition in any manner whatsoever with the Company or any of its Affiliates. 

(b)    Disclosure and Authorization. In consideration of the Company’s promises herein, for a period of
24 months immediately following the termination of Executive’s employment for any reason, Executive promises to disclose to the Company any employment, consulting, or other service relationship Executive enters into after the termination of
Executive’s employment with the Company for any reason. Such disclosure shall be made within 7 days of Executive entering into such employment, consulting or other service relationship. Executive expressly consents to and authorizes the Company
to disclose both the existence and terms of this Agreement to any future employer or user of Executive’s services and to take any steps the Company deems necessary to enforce this Agreement. 

(c)    Requests for Modification. Executive represents that Executive is willing and able to engage in other
employment not prohibited by this Agreement. In the event Executive subsequently decides that Executive would like to pursue an opportunity prohibited by the terms of this Agreement, Executive agrees to make written request to Company for a
modification of the restrictions contained in this Agreement prior to pursuing the opportunity, such request to include the name and address of the organization or entity involved (if any) and the title, nature, and duties of the activity Executive
wishes to pursue. Executive agrees and understands that the Company is under no obligation whatsoever to grant any such modification and will decide any such request in its sole and absolute discretion. 

(d)    Value and Reasonableness. Executive understands and acknowledges that the Company has made
substantial investments to develop its business interests, goodwill, 

  
 13 








 
and Confidential Information. Executive agrees that such investments are worthy of protection, and that the Company’s need for the protection afforded by this
Section 10 is greater than any hardship Executive might experience by complying with its terms and that the restrictions contained herein are necessary to protect the Company’s legitimate business interests. Executive
agrees that the limitations as to time, geographic area, and scope of activity to be restrained contained in this Agreement are reasonable and are not greater than necessary to protect the Confidential Information and/or the goodwill or other
business interests of the Company. 
 (e)    Reformation Requested. The Company and Executive believe the
limitations as to time, geographic area, and scope of activity contained in this Section 10 are reasonable and do not impose a greater restraint than necessary to protect Confidential Information, goodwill, and other
legitimate business interests of the Company. However, in the event an arbitrator or court of competent jurisdiction determines that the limitations agreed upon are not appropriate, the parties agree to, and hereby do, request that the court reform
the limitations to the satisfaction of the court. It is the express intent of the Company and Executive that the terms of this Competition Agreement be enforced to the full extent permitted by law and not to any greater extent. 

(f)    Right to Injunction. Executive acknowledges that Executive’s violation of
Sections 9 and/or 10 of this Agreement will cause irreparable harm to the Company for which damages cannot adequately be measured, and Executive agrees that the Company shall be entitled as a matter of right to
specific performance of Executive’s obligations under Sections 9 and 10 and an injunction, from any court of competent jurisdiction, restraining any violation or further violation of such agreements by
Executive or others acting on his/her behalf, without any showing of irreparable harm and without any showing that the Company does not have an adequate remedy at law. The Company’s right to injunctive relief shall be cumulative and in addition
to any other remedies provided by law or equity. 
 (g)    “Competing Business” means any
individual, sole proprietorship, business, firm, company, partnership, joint venture, organization, or other person, entity or arrangement that competes, or has plans to compete, or that owns or controls a significant interest in any entity that

(b)    Each side shall share equally the cost of the arbitrator and bear its own costs and attorneys’ fees incurred

breach of any provision of this Agreement by the other party, or of compliance with any condition or provision of this Agreement to be performed by such other party, will operate or be construed as a waiver of any subsequent breach by such other
party or any similar or dissimilar provision or condition at the same or any subsequent time. The failure of either party hereto to take any action by reason of any breach will not deprive such party of the right to take action at any time while
such breach continues.

the other party in writing in accordance with this Section 21. 

22.    Section 409A. 

(a)    General. The intent of the Parties is that the payments and benefits under this Agreement comply with
or be exempt from Section 409A of the Internal Revenue Code of 

  
 18 








 
1986, as amended, (the “Code”) and the regulations and guidance promulgated thereunder (collectively,
“Section 409A”) and, accordingly, to the maximum extent permitted, this Agreement shall be interpreted to be in compliance therewith. The Company and Executive shall take commercially
reasonable efforts to reform or amend any provision hereof to the extent that either of them reasonably determine that such provision would or could reasonably be expected to cause Executive to incur any additional tax or interest under
Section 409A to try to comply with or be exempt from Section 409A through good faith modifications, in any case, to the minimum extent reasonably appropriate to conform with Section 409A, provided that any such modifications shall not
increase the cost or liability to the Company. To the extent that any provision hereof is modified in order to comply with or be exempt from Section 409A, such modification shall be made in good faith and shall, to the maximum extent reasonably
possible, maintain the original intent and economic benefit to Executive and the Company of the applicable provision without violating the provisions of Section 409A. 

(b)    Separation from Service. Notwithstanding anything in this Agreement to the contrary, any compensation
or benefits payable under this Agreement that is designated under this Agreement as payable upon Executive’s termination of employment shall be payable only upon Executive’s “separation from service” with the Company within the
meaning of Section 409A (a “Separation from Service”). 
 (c)    Specified
Employee. Notwithstanding anything in this Agreement to the contrary, if Executive is deemed by the Company at the time of Executive’s Separation from Service to be a “specified employee” for purposes of Section 409A, to
the extent delayed commencement of any portion of the benefits to which Executive is entitled under this Agreement is required in order to avoid a prohibited distribution under Section 409A, such portion of Executive’s benefits
shall not be provided to Executive prior to the earlier of (i) the expiration of the six-month period measured from the date of Executive’s Separation from Service or (ii) the date of
Executive’s death. Upon the first business day following the expiration of the delay period described in the preceding sentence, all payments deferred pursuant to the preceding sentence shall be paid in a lump sum to Executive (or
Executive’s estate or beneficiaries), and any remaining payments due to Executive under this Agreement shall be paid as otherwise provided herein. 

(d)    Expense Reimbursements. To the extent that any reimbursements under this Agreement are subject to
Section 409A, any such reimbursements payable to Executive shall be paid to Executive no later than December 31 of the year following the year in which the expense was incurred; provided, that Executive submits Executive’s
reimbursement request promptly following the date the expense is incurred, the amount of expenses reimbursed in one year shall not affect the amount eligible for reimbursement in any subsequent year, other than medical expenses referred to in
Section 105(b) of the Code, and Executive’s right to reimbursement under this Agreement will not be subject to liquidation or exchange for another benefit. 

(e)    Installments. Executive’s right to receive any installment payments under this Agreement,
including without limitation any continuation salary payments that are payable on Company payroll dates, shall be treated as a right to receive a series of separate payments and, accordingly, each such installment payment shall at all times be
considered a separate and 

  
 19 








 
distinct payment as permitted under Section 409A. Except as otherwise permitted under Section 409A, no payment hereunder shall be accelerated or deferred unless such acceleration or
deferral would not result in additional tax or interest pursuant to Section 409A. 
 23.    Executive
Acknowledgement. Executive acknowledges that Executive has read and understands this Agreement, is fully aware of its legal effect, has not acted in reliance upon any representations or promises made by the Company other than those contained
in writing herein, and has entered into this Agreement freely based on Executive’s own judgment. 

24.    Counterparts. This Agreement may be executed in any number of counterparts, each of which when so
executed and delivered shall be an original, but all such counterparts shall together constitute one and the same instrument. Each counterpart may consist of a copy hereof containing multiple signature pages, each signed by one party, but together
signed by both parties hereto.

Party permit any of its Affiliates to, directly or indirectly, for Restricted Party’s or its respective Affiliate’s account engage (or assist any other Person) in Competition with the Protected Parties or any Affiliate of the Protected
Parties or enter into discussions or negotiations to do any of the foregoing. Notwithstanding anything herein to the contrary, the Parties acknowledge and agree that the Restricted Party may own or hold, as a passive investment, not more than two

 ARTICLE IV 

RELIEF 

4.1    Restrictions Reasonable. Restricted Party acknowledges that the Term, the Protected Area, and the
nature of the restrictions agreed upon pursuant to this Agreement are reasonable and necessary for the protection of the Protected Parties and their Affiliates. It is expressly understood that if a court of competent jurisdiction shall find the
foregoing restrictive covenants to be invalid or unenforceable by reason of being too broad in scope, then any or all of such invalid or unenforceable provisions shall be amended by said court so as to cause said restrictive covenant to be valid and
enforceable to the fullest extent permitted by law. 
 4.2    Injunctive Relief. The Restricted Party
agrees and acknowledges that a remedy at law for any breach or attempted breach of this Agreement hereof will be inadequate and that any such breach or attempted breach will result in irreparable harm to the Protected Parties and their Affiliates
for which no adequate remedy at law exists. Accordingly, the Protected Parties shall, in addition to any other remedy that may be available, be entitled to obtain injunctive relief and specific performance, including temporary restraining orders,
preliminary injunctions and permanent injunctions, requiring compliance with the terms of this Agreement. 

4.3    Conveyance of Acquired Interests. The Restricted Party acknowledges that the granting of injunctive
relief may not adequately compensate the Protected Parties for damages resulting from any breach of Article II. Accordingly, the Protected Parties may seek actual damages from the Restricted Party for each and every breach by the Restricted
