(c) Continued Compliance with Securities Laws. If, at any time when a prospectus relating to the Offered Securities is (or but for the exemption in Rule 172 would be) required to be delivered under the Act by the Underwriter or any dealer, any event occurs as a result of which the Final Prospectus as then amended or supplemented would include an untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, or if it is necessary at any time to amend the Registration Statement or supplement the Final Prospectus to comply with the Act, the Company will promptly notify the Underwriter of such event and will promptly prepare and file with the Commission and furnish, at its own expense, to the Underwriter and any dealers upon request of the Underwriter, an amendment or supplement which will correct such statement or omission or an amendment which will effect such compliance.

(b) Indemnification of the Company by the Underwriter. The Underwriter will indemnify and hold harmless the Company, each of its directors and each of its officers who signs the Registration Statement and each person, if any, who controls the Company within the meaning of Section 15 of the Act or Section 20 of the Exchange Act (each, an “Underwriter Indemnified Party”) against any losses, claims, damages or liabilities to which such Underwriter Indemnified Party may become subject, under the Act, the Exchange Act, or other federal or state statutory law or regulation or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in any part of any Registration Statement at any time, any Statutory Prospectus as of any time, the Final Prospectus or any Issuer Free Writing Prospectus or arise out of or are based upon the omission or the alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information furnished to the Company by or on behalf the Underwriter specifically for use therein, and will reimburse any legal or other expenses reasonably incurred by such Underwriter Indemnified Party in connection with investigating or defending against any such loss, claim, damage, liability, action, litigation, investigation or proceeding whatsoever (whether or not such Underwriter Indemnified Party is a party thereto), based upon any such untrue statement or omission, or any such alleged

(c) Actions against Parties; Notification. Promptly after receipt by an indemnified party under this Section of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against an indemnifying party under subsection (a) or (b) above, notify the indemnifying party of the commencement thereof; but the failure to notify the indemnifying party shall not relieve it from any liability that it may have under subsection (a) or (b) above except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided further that the failure to notify the indemnifying party shall not relieve it from any liability that it may have to an indemnified party otherwise than under subsection (a) or (b) above. In case any such action is brought against any indemnified party and it notifies an indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party will not be liable to such indemnified party under this Section for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened action in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party unless such settlement (i) includes an unconditional release of such indemnified party from all liability on any claims that are the subject matter of such action and (ii) does not include a statement as to, or an admission of, fault, culpability or a failure to act by or on behalf of an indemnified party.

(d) Contribution. If the indemnification provided for in this Section is unavailable or insufficient to hold harmless an indemnified party under subsection (a) or (b) above, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of the losses, claims, damages or liabilities referred to in subsection (a) or (b) above (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriter on the other from the offering of the Securities or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company on the one hand and the Underwriter on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriter on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company bear to the total underwriting discounts and commissions received by the Underwriter. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or the Underwriter and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The amount paid by an indemnified party as a result of the losses, claims, damages or liabilities referred to in the first sentence of this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any action or claim which is the subject of this subsection (d). Notwithstanding the provisions of this subsection (d), the Underwriter shall not be required to contribute any amount in excess of the amount by which the total price at which the Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which the Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Company and the Underwriter agree that it would not be just and equitable if contribution pursuant to this Section 8(d) were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to in this Section 8(d).

9. Survival of Certain Representations and Obligations. The respective indemnities, agreements, representations, warranties and other statements of the Company or its officers and of the Underwriter set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation, or statement as to the results thereof, made by or on behalf of the Underwriter, the Company or any of their respective representatives, officers or directors or any controlling person, and will survive delivery of and payment for the Offered Securities. If the purchase of the Offered Securities by the Underwriter is not consummated for any reason other than solely because of the termination of this Agreement pursuant to Section 9 or the occurrence of any event specified in clause (iv), (vi) or (vii) of Section 7(d) hereof, the Company will reimburse the Underwriter for all out-of-pocket expenses (including fees and disbursements of counsel) reasonably incurred by them in connection with the offering of the Offered Securities, and the respective obligations of the Company and the Underwriter pursuant to Section 8 hereof shall remain in effect.

Ladies and Gentlemen:

As an inducement to the underwriter to execute the Underwriting Agreement (the “Underwriting Agreement”), pursuant to which an offering (the “Offering”) will be made of shares of the common stock (the “Securities”) of Talos Energy Inc., and any successor (by merger or otherwise) thereto (the “Company”), the undersigned hereby agrees that during the period specified in the following paragraph (the “Lock-Up Period”), the undersigned will not offer, sell, contract to sell, pledge or otherwise dispose of, directly or indirectly, any Securities or securities convertible into or exchangeable or exercisable for any Securities, enter into a transaction that would have the same effect, or enter into any swap, hedge or other arrangement that transfers, in whole or in part, any of the economic consequences of ownership of the Securities, whether any such aforementioned transaction is to be settled by delivery of the Securities or such other securities, in cash or otherwise, or publicly disclose the intention to make any such offer, sale, pledge or disposition, or to enter into any such transaction, swap, hedge or other arrangement, without, in each case, the prior written consent of BMO Capital Markets Corp. (“BMO”). In addition, the undersigned agrees that, without the prior written consent of BMO, it will not, during the Lock-Up Period, make any demand for or exercise any right with respect to, the registration of any Securities or any security convertible into or exercisable or exchangeable for the Securities.

The Lock-Up Period will commence on the date of this Lock-Up Agreement and continue and include the date that is 60 days after the public offering date set forth on the final prospectus used to sell the Securities (the “Public Offering Date”) pursuant to the Underwriting Agreement, to which you are or expect to become parties.

Notwithstanding the foregoing, the restrictions in this Lock-Up Agreement shall not apply to: (i) transfers of Securities or any securities convertible into or exercisable or exchangeable for Securities (a) as a bona fide gift or gifts; (b) to a family member, trust or family partnership (for purposes of this Lock-Up Agreement, a “family member” shall mean any relationship by blood, marriage, domestic partnership or adoption, not more remote than first cousin); (c) to a corporation, partnership, limited liability company, trust or other entity of which the undersigned and the immediate family of the undersigned are the legal and beneficial owner of all of the outstanding equity securities or similar interests; or (d) to a nominee or custodian of a person or entity to whom a disposition or transfer would be permissible under the foregoing clauses (a) through (c); (ii) if the undersigned is a corporation, limited liability company or limited partnership, any transfer of Securities or any securities convertible into or exercisable or exchangeable for Securities to (a) its limited or general partners, members or stockholders or (b) its affiliates or other entities controlled or managed by the undersigned or any of its affiliates (other than the Company and its subsidiaries); (iii) the exercise of options or vesting or settlement of any other equity-based award, in each case, granted under the Talos Energy Inc. Long Term Incentive Plan, including any Securities withheld by the Company to pay the applicable exercise price or taxes associated with such awards, provided, however, that any Securities received upon such exercise, vesting or settlement, following any applicable net settlement or net withholding, will be subject to the restrictions of this Lock-Up Agreement; (iv) any Securities acquired by the undersigned in the open market after completion of the Offering; (v) the transfer or disposition of any Securities (a) as a result of the operation of law, or pursuant to an order of a court (including a domestic order, divorce settlement, divorce decree, or separation agreement) or regulatory agency or (b) by will, other testamentary document or intestate succession; (vi) the repurchase of Securities by the Company pursuant to equity award agreements or other contractual arrangements providing for the right of said

Exhibit B-1

repurchase in connection with the termination of the undersigned’s employment or service with the Company; (vii) the entering into by the undersigned of a written trading plan (“Rule 10b5-1 Plan”) pursuant to Rule 10b5-1 of the Exchange Act of 1934, as amended (the “Exchange Act”) during the Lock-Up Period, provided that no sales or transfers of Securities shall be made pursuant to such Rule 10b5-1 Plan prior to the expiration of the Lock-Up Period and no filing under the Exchange Act or other public announcement shall be required or voluntarily made by the undersigned or any other person in connection therewith without the permission of BMO, prior to the expiration of the Lock-Up Period; and (viii) transfers or sales of Securities pursuant to any Rule 10b5-1 Plan that has been entered into by the undersigned prior to the date of this Letter Agreement, provided that any filing required to be made under Section 16(a) of the Exchange Act as a result of such transfer or sale shall state that such transfer or sale is pursuant to a trading plan pursuant to Rule 10b5-1; provided that in the case of any transfer or distribution pursuant to clause (i), (1) each donee, distributee or transferee shall agree to be bound in writing by the restrictions set forth herein, (2) such transfer or distribution shall not involve a disposition for value and (3) no filing by the undersigned or any party (donor, donee, transferor or transferee) under the Exchange Act, or other public announcement, shall be voluntarily made in connection with any such transfer, and if the undersigned is required to file a report under the Exchange Act in connection with such transfer during the Lock-Up Period, the undersigned shall include a statement in such report to the effect that the filing relates to a bona fide gift or that such transfer or other disposition of Securities, as applicable, or any security convertible into Securities, is to an immediate family member, an entity of which the undersigned and the immediate family of the undersigned are the legal and beneficial owner of all of the outstanding equity securities or similar interests, or a nominee or custodian of an immediately family member or such entity, and not a disposition for value; and provided, further, that in the case of any transfer pursuant to clause (ii), (1) that the transferee agrees to be bound in writing by the terms of this Lock-Up Agreement prior to such transfer, (2) such transfer does not involve a disposition for value and (3) no filing or public announcement by any party (transferor or transferee) under the Exchange Act, or other public announcement, shall be voluntarily made in connection with any such transfer, and if the undersigned is required to file a report under the Exchange Act in connection with such transfer during the Lock-Up Period, the undersigned shall include a statement in such report to the effect that the filing relates to a transfer or other disposition of Securities, as applicable, or any security convertible into Securities, to such entity’s limited or general partners, members or stockholders or its affiliates or other entities controlled or managed by the undersigned; and provided, further, that in the case of any transfer pursuant to clause (v), no filing by the undersigned or any party (transferor or transferee) under the Exchange Act, or other public announcement, shall be voluntarily made in connection with any such transfer, and if the undersigned is required to file a report under the Exchange Act related thereto during the Lock-Up Period, such report shall disclose that such transfer was as a result of the operation of law, or pursuant to an order of a court or regulatory agency or by will, other testamentary document or intestate succession; and provided, further, that in the case of any transfer pursuant to clause (vi), no filing by the undersigned under the Exchange Act, or other public announcement, shall be voluntarily made in connection with any such transfer, and if the undersigned is required to file a report under the Exchange Act related thereto during the Lock-Up Period, such report shall disclose that such transfer was a result of the repurchase of Securities by the Company pursuant to equity award agreements or other contractual arrangements in connection with the termination of the undersigned’s employment or service with the Company. The Company and BMO acknowledge and agree that any other Lock-Up Agreement executed in connection with the Offering shall contain the same terms as provided herein and to the extent any person is released or otherwise granted a waiver or modification of its Lock-Up Agreement executed in connection with the Offering, the undersigned shall be simultaneously granted the same release, waiver of modification with respect to this Lock-Up Agreement.

In furtherance of the foregoing, the Company and its transfer agent and registrar are hereby authorized to decline to make any transfer of Securities if such transfer would constitute a violation or breach of this Lock-Up Agreement.

This Lock-Up Agreement shall be binding on the undersigned and the successors, heirs, personal representatives and assigns of the undersigned. This Lock-Up Agreement shall lapse and become null and void if the Public Offering Date shall not have occurred on or before January 31, 2020, or upon notification by the Company to the Underwriter that it does not intend to proceed with the Offering. This agreement shall be governed by, and construed in accordance with, the laws of the State of New York.
