2.1 Filing of Registration Statement.

2.1.1 Pursuant to the Act. The Company has filed with the Securities and Exchange Commission (the “Commission”) a registration statement and an amendment or amendments thereto, on Form S-1 (File No. 333-204591), including any related prospectus or prospectuses, for the registration of the Public Securities under the Securities Act of 1933, as amended (the “Act”), which registration statement and amendment or amendments have been prepared by the Company in all material respects in conformity with the requirements of the Act and the rules and regulations of the Commission under the Act (the “Regulations”). Except as the context may otherwise require, such registration statement on file with the Commission at the time the registration statement becomes effective (the “Effective Date”) (including the prospectus, financial statements, schedules, exhibits and all other documents filed as a part thereof or incorporated therein and all information deemed to be a part thereof as of the Effective Date pursuant to paragraph (b) of Rule 430A of the Regulations), is referred to herein as the “Registration Statement.” The final prospectus in the form first furnished to the Underwriters for use in the Offering, is hereinafter called the “Prospectus.” The Registration Statement has been declared effective by the Commission. “Applicable Time” means 5:45 pm, Eastern time, on July 9, 2015, or such other time as agreed to by the Company and the Representatives.

2.2 No Stop Orders. Neither the Commission nor, to the best of the Company’s knowledge, any state regulatory authority has issued any order preventing or suspending the use of the Prospectus or the Registration Statement or has instituted or, to the best of the Company’s knowledge, threatened to institute any proceedings with respect to such an order.

2.3 Disclosures in Registration Statement.

2.3.1 10b-5 Representation. At the Applicable Time and at the respective times the Registration Statement, the Prospectus and any post-effective amendments thereto become effective (and at the Closing Date and the Option Closing Date, if any):

(i) The Registration Statement, the Prospectus and any post-effective amendments thereto did and will in all material respects conform to the requirements of the Act and the Regulations;

(ii) Neither the Registration Statement nor the Prospectus, nor any amendment or supplement thereto, on such dates, do or will contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading. The representation and warranty made in this Section 2.3.1(ii) does not apply to statements made or statements omitted in reliance upon and in conformity with written information furnished to the Company with respect to the Underwriters by the Representatives expressly for use in the Registration Statement or Prospectus or any amendment thereof or supplement thereto. The parties acknowledge and agree that such information provided by or on behalf of any Underwriters consists solely of the disclosure contained in the “Stabilization” paragraph under the caption “Underwriting (Conflicts of Interest)” of the Prospectus (the “Underwriters’ Information”).

2.3.2 Disclosure of Agreements. The agreements and documents described in the Prospectus and the Registration Statement conform to the descriptions thereof contained therein and there are no agreements or other documents required by the Act and the Regulations to be described in the Prospectus, the Registration Statement or to be filed with the Commission as exhibits to the Registration Statement, that have not been so described or filed. Each agreement or other instrument (however characterized or described) to which a Company Entity is a party or by which it is or may be bound or affected and (i) that is referred to in the Prospectus, or (ii) is material to such Company Entity’s business, has been duly authorized and validly executed by the applicable Company Entity, is in full force and effect in all material respects and is enforceable against the Company Entity and, to the Company’s knowledge, the other parties thereto, in accordance with its terms, except (x) as such enforceability may be limited by bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance or transfer or similar laws affecting creditors’ rights generally, (y) as enforceability of any indemnification or contribution provision may be limited under the federal and state securities laws, and (z) that the remedy of specific performance and injunctive and other forms of equitable relief may be subject to the equitable defenses and to the discretion of the court before which any proceeding therefore may be brought. None of such agreements or instruments has been assigned by a Company Entity, and no Company Entity nor, to the best of the Company’s knowledge, any other party is in default thereunder and, to the best of the Company’s knowledge, no event has occurred that, with the lapse of time or the giving of notice, or both, would constitute a default thereunder. To the best of the Company’s knowledge, performance by a Company Entity of the material provisions of such agreements or instruments will not result in a violation of any existing applicable law, rule, regulation, judgment, order or decree of any governmental agency or court, domestic or foreign, having jurisdiction over the Company Entity or any of its assets or businesses, including, without limitation, those relating to environmental laws and regulations.

2.3.3 Prior Securities Transaction. No securities of the Company have been sold by the Company or by or on behalf of, or for the benefit of, any person or persons controlling, controlled by, or under common control with the Company, except as disclosed in the Registration Statement.

Except as described in the Registration Statement, (x) there are no proceedings pending, or known to be contemplated, against the Company under Environmental Laws in which a governmental authority is also a party, other than any such proceedings with respect to which it is reasonably believed that no monetary sanctions of $50,000 or more will be imposed and (y) the Company does not anticipate material capital expenditures relating to Environmental Laws other than those incurred in the ordinary course of business for the purchase of equipment used in its business activities. The term “Hazardous Material” means (A) any “hazardous substance” as defined in the Comprehensive Environmental Response Compensation and Liability Act of 1980, as amended, (B) any “hazardous waste” as defined in the Resource Conservation and Recovery Act of 1976, as amended, (C) any petroleum or petroleum product, (D) any polychlorinated biphenyl and (E) any pollutant or contaminant or hazardous, dangerous or toxic chemical, material, waste or substance regulated under or within the meaning of any Environmental Law.

No “reportable event” (as defined in ERISA) has occurred or is reasonably expected to occur with respect to any “employee benefit plan” established or maintained by the Company or any of its ERISA Affiliates. No “employee benefit plan” established or maintained by the Company or any of its ERISA Affiliates, if such “employee benefit plan” were terminated, would have any “amount of unfunded benefit liabilities” (as defined in ERISA).

Each “employee benefit plan” established or maintained by the Company or any of its ERISA Affiliates that is intended to be qualified under Section 401(a) of the Code is so qualified and nothing has occurred, whether by action or failure to act, that would cause the loss of such qualification.

2.31 Insurance. The Company is insured by insurers of recognized financial responsibility against such losses and risks and in such amounts as are prudent and customary in the businesses in which it is engaged, and the Company does not have reason to believe that it will not be able to renew its existing insurance coverage as and when such coverage expires or to obtain similar coverage from similar insurers as may be necessary to continue its business at a comparable cost.

2.32 Forward-Looking Statements. Each statement (including the assumptions described therein) included in the Registration Statement that is within the coverage of Rule 175(b), including, but not limited to, any statements with respect to projected results of operations and any statements made in support thereof, was made or will be made by the Company with a reasonable basis and in good faith.

2.34 No Broker’s Fees. No Company Entity is a party to any contract, agreement or understanding with any person (other than this Agreement) that would give rise to a valid claim against a Company Entity or any Underwriter for a brokerage commission, finder’s fee or like payment in connection with the offering and sale of the Shares.

Such Underwriter or controlling person shall have the right to employ its or their own counsel in any such case, but the fees and expenses of such counsel shall be at the expense of such Underwriter or such controlling person unless the employment of such counsel shall have been authorized in writing by the Company in connection with the defense of such action, or the Company shall not have employed counsel to have charge of the defense of such action within a reasonable time or such indemnified party or parties shall have reasonably concluded (based on the advice of counsel) that there may be defenses available to it or them which are different from or additional to those available to the Company in which case the Company shall have the right to direct the defense of such action on behalf of the indemnified party or parties), in any of which events such fees and expenses shall be borne by the Company and paid as incurred (it being understood, however, that the Company shall not be liable for the expenses of more than one separate firm of attorneys for the Underwriters or controlling persons in any one action or series of related actions in the same jurisdiction (other than local counsel in any such jurisdiction) representing the indemnified parties who are parties to such action). Anything in this paragraph to the contrary notwithstanding, the Company shall not be liable for any settlement of any such claim or action effected without its consent.

5.3 Indemnity by the Underwriters. Each Underwriter, severally and not jointly, agrees to indemnify, defend and hold harmless the Company, the Company’s directors, the Company’s officers that signed the Registration Statement, and any person who controls the Company within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, from and against any loss, expense, liability, damage or claim (including the reasonable cost of investigation) which the Company or any such person may incur under the Act, the Exchange Act or otherwise, insofar as such loss, expense, liability, damage or claim arises out of or is based upon (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or any amendment), the Prospectus, or any Application, (ii) any omission or alleged omission to state a material fact required to be stated in any such Registration Statement, or necessary to make the statements made therein not misleading, or (iii) any omission or alleged omission from the Prospectus or any Application of a material fact necessary to make the statements made therein, in the light of the circumstances under which they were made, not misleading, but in each case only insofar as such untrue statement or alleged untrue statement or omission or alleged omission was made in such Registration Statement, Prospectus or Application in reliance upon and in conformity with information furnished in writing by the Representatives to the Company expressly for use therein. The Underwriters’ Information in the preliminary prospectus and the Prospectus (to the extent such statements relate to the Underwriters) constitute the only information furnished by or on behalf of any Underwriter through the Representatives to the Company for purposes of Section 2.3.1 and this Section 5.

5.4 Underwriters’ Indemnification Procedures. If any action is brought against the Company, or any such person in respect of which indemnity may be sought against any Underwriter pursuant to Section 5.3, the Company, or such person shall promptly notify the Representatives in writing of the institution of such action and the Representatives, on behalf of the Underwriters, shall assume the defense of such action, including the employment of counsel and payment of expenses. The Company, or such person shall have the right to employ its own counsel in any such case, but the fees and expenses of such counsel shall be at the expense of the Company, or such person unless the employment of such counsel shall have been authorized in writing by the Representatives in connection with the defense of such action or the Representatives shall not have employed counsel to have charge of the defense of such action within a reasonable time or such indemnified party or parties shall have reasonably concluded (based on the advice of counsel) that there may be defenses available to it or them which are different from or additional to those available to the Underwriters (in which case the Representatives shall not have the right to direct the defense of such action on behalf of the indemnified party or parties), in any of which events such fees and expenses shall be borne by the Underwriters and paid as incurred (it being understood, however, that the Underwriters shall not be liable for the expenses of more than one separate firm of attorneys in any one action or series of related actions in the same jurisdiction (other than local counsel in any such jurisdiction) representing the indemnified parties who are parties to such action). Anything in this paragraph to the contrary notwithstanding, no Underwriter shall be liable for any settlement of any such claim or action effected without the written consent of the Representatives.

5.5 Contribution. If the indemnification provided for in this Section 5 is unavailable or insufficient to hold harmless an indemnified party under Sections 5.1 or 5.3 in respect of any losses, expenses, liabilities, damages or claims referred to therein, then each applicable indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, expenses, liabilities, damages or claims (i) in such proportion as is appropriate to reflect the relative benefits received by the Company, and the Underwriters from the offering of the Shares or (ii) if (but only 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, and of the Underwriters in connection with the statements or omissions which resulted in such losses, expenses, liabilities, damages or claims, as well as any other relevant equitable considerations. The relative benefits received by the Company, and the Underwriters shall be deemed to be in the same proportion as the total proceeds from the offering (net of underwriting discounts and commissions but before deducting expenses) received by the Company bear to the underwriting discounts and commissions received by the Underwriters. The relative fault of the Company, and of the Underwriters shall be determined by reference to, among other things, whether the untrue statement or alleged untrue statement of a material fact or omission or alleged omission relates to information supplied by the Company, or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The amount paid or payable by a party as a result of the losses, claims, damages and liabilities referred to above shall be deemed to include any legal or other fees or expenses reasonably incurred by such party in connection with investigating or defending any claim or action.

5.6 Limitation of Liability. The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 5 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to in Section 5.5. Notwithstanding the provisions of this Section 5, no Underwriter shall be required to contribute any amount in excess of the underwriting discounts and commissions applicable to the Shares purchased by such Underwriter. 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 Underwriters’ obligations to contribute pursuant to this Section 5 are several in proportion to their respective underwriting commitments and not joint.

6. Default by an Underwriter.

6.1 Default Not Exceeding 10% of Firm Shares or Option Shares. If any Underwriter or Underwriters shall default in its or their obligations to purchase the Firm Shares or the Option Shares, if the Option is exercised, hereunder, and if the number of the Firm Shares or Option Shares with respect to which such default relates does not exceed in the aggregate 10% of the number of Firm Shares or Option Shares that all Underwriters have agreed to purchase hereunder, then such Firm Shares or Option Shares to which the default relates shall be purchased by the non-defaulting Underwriters in proportion to their respective commitments hereunder.

6.2 Default Exceeding 10% of Firm Shares or Option Shares. In the event that the default addressed in Section 6.1 relates to more than 10% of the Firm Shares or Option Shares, you may in your discretion arrange for yourself or for another party or parties to purchase such Firm Shares or Option Shares to which such default relates on the terms contained herein. If, within one (1) Business Day after such default relating to more than 10% of the Firm Shares or Option Shares, you do not arrange for the purchase of such Firm Shares or Option Shares, then the Company shall be entitled to a further period of one (1) Business Day within which to procure another party or parties satisfactory to you to purchase said Firm Shares or Option Shares on such terms. In the event that neither the Underwriters nor the Company arrange for the purchase of the Firm Shares or Option Shares to which a default relates as provided in this Section 6, this Agreement will automatically be terminated by you or the Company without liability on the part of the Company (except as provided in Section 5 hereof) or the several Underwriters (except as provided in Section 5 hereof); provided, however, that if such default occurs with respect to the Option Shares, this Agreement will not terminate as to the Firm Shares; and provided further that nothing herein shall relieve a defaulting Underwriter of its liability, if any, to the other Underwriters and to the Company for damages occasioned by its default hereunder.

6.3 Postponement of Closing Date. In the event that the Firm Shares or Option Shares to which the default relates are to be purchased by the non-defaulting Underwriters, or are to be purchased by another party or parties as aforesaid, you or the Company shall have the right to postpone the Closing Date or Option Closing Date for a reasonable period, but not in any event exceeding five (5) Business Days, in order to effect whatever changes may thereby be made necessary in the Registration Statement or the Prospectus or in any other documents and arrangements, and the Company agrees to file promptly any amendment to the Registration Statement or the Prospectus that in the opinion of AK may thereby be made necessary. The term “Underwriter” as used in this Agreement shall include any party substituted under this Section 6 with like effect as if it had originally been a party to this Agreement with respect to such Public Securities.

7. Effective Date of this Agreement and Termination Thereof.

7.1 Effective Date. This Agreement shall become effective when both the Company and the Representatives have executed the same and delivered counterparts of such signatures to the other party.

7.2 Termination. You shall have the right to terminate this Agreement at any time prior to any Closing Date, (i) if any domestic or international event or act or occurrence has materially disrupted, or in your opinion will in the immediate future materially disrupt, general securities markets in the United States; or (ii) if trading on the New York Stock Exchange, the NASDAQ, the NASDAQ Global Market or the NASDAQ Capital Market shall have been suspended or materially limited, or minimum or maximum prices for trading shall have been fixed, or maximum ranges for prices for securities shall have been required by FINRA or by order of the Commission or any other government authority having jurisdiction, or (iii) if the United States shall have become involved in a new war or an increase in major hostilities, or (iv) if a banking moratorium has been declared by a New York State or federal authority, or (v) if a moratorium on foreign exchange trading has been declared which materially adversely impacts the United States securities markets, or (vi) if the Company shall have sustained a material loss by fire, flood, accident, hurricane, earthquake, theft, sabotage or other calamity or malicious act which, whether or not such loss shall have been insured, will, in your opinion, make it inadvisable to proceed with the delivery of the Firm Shares or Option Shares, or (vii) if the Company is in material breach of any of its representations, warranties or covenants hereunder, or (viii) if the Representatives shall have become aware after the date hereof of such a material adverse change in the conditions or prospects of the Company, or such adverse material change in general market conditions as in the Representatives’ judgment would make it impracticable to proceed with the offering, sale and/or delivery of the securities or to enforce contracts made by the Underwriters for the sale of the securities.

7.3 Expenses. In the event that this Agreement shall not be carried out for any reason whatsoever, within the time specified herein or any extensions thereof pursuant to the terms herein, the Company shall be obligated to pay to the Underwriters their actual and accountable and reasonable out of pocket expenses related to the transactions contemplated herein then due and payable (including the fees and disbursements of AK up to $125,000; provided, however, that such expense cap in no way limits or impairs the indemnification and contribution provisions of this Agreement).

7.4 Indemnification. Notwithstanding any contrary provision contained in this Agreement, any election hereunder or any termination of this Agreement, and whether or not this Agreement is otherwise carried out, the provisions of Section 5 shall not be in any way effected by, such election or termination or failure to carry out the terms of this Agreement or any part hereof.

8. Miscellaneous.

8.1 Notices. All communications hereunder, except as herein otherwise specifically provided, shall be in writing and shall be mailed (registered or certified mail, return receipt requested), personally delivered or sent by facsimile transmission and confirmed and shall be deemed given when so delivered or faxed and confirmed or if mailed, two (2) days after such mailing.

Ladies and Gentlemen:

The undersigned understands that FBR Capital Markets & Co. and Xxxx Capital Partners, LLC (each a “Representative” and together, the “Representatives”) propose to enter into an Underwriting Agreement (the “Underwriting Agreement”) with Eco-Stim Energy Solutions, Inc., a Nevada corporation (the “Company”), providing for the public offering (the “Public Offering”) by the Underwriters named on Schedule I thereto (the “Underwriters”) of __________ shares of common stock (“Firm Shares”), par value $0.001 per share, of the Company (the “Shares”).

To induce the Representatives to continue its efforts in connection with the Public Offering, the undersigned hereby agrees that, without the prior written consent of the Representatives, it will not, during the period commencing on the date hereof and ending 90 days after the date of the final prospectus (the “Prospectus”) relating to the Public Offering (the “Lock-Up Period”), (1) offer, pledge, sell, contract to sell, grant, lend, or otherwise transfer or dispose of, directly or indirectly, any Shares or any securities convertible into or exercisable or exchangeable for Shares, or (2) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of the Shares, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Shares or such other securities, in cash or otherwise. Notwithstanding the foregoing, the undersigned may transfer Shares without the prior consent of the Representatives in connection with (a) transactions relating to Shares or other securities acquired in open market transactions after the completion of the Public Offering; provided that, no filing under Section 16(a) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), shall be required or shall be voluntarily made in connection with subsequent sales of Shares or other securities acquired in such open market transactions, (b) if the undersigned is an individual, transfers of Shares or any security convertible into Shares as a bona fide gift, by will or intestacy or to a family member or trust for the benefit of a family member; provided that, in the case of any transfer or distribution pursuant to clause (b), (i) each donee or distributee shall sign and deliver a lock-up letter substantially in the form of this letter agreement and (ii) no filing under Section 16(a) of the Exchange Act, reporting a reduction in beneficial ownership of Shares, shall be required or shall be voluntarily made during the Lock-up Period, (c) transfer of Shares to a charity or educational institution, (d) if the undersigned is, or directly or indirectly controls, a corporation, partnership, limited liability company or other business entity, any transfers of Shares to any shareholder, partner or member of, or owner of similar equity interests in, the undersigned, as the case may be, if, in any such case, such transfer is not for value, (e) Shares disposed of to satisfy federal income tax and tax withholding obligations in conjunction with the issuance or vesting of equity incentive awards in accordance with the terms of any plan or award agreement relating to such equity incentive awards or (f) if the undersigned is a corporation, partnership, limited liability company or other business entity, any transfer of Shares made by the undersigned (i) in connection with the sale or other bona fide transfer in a single transaction of all or substantially all of the undersigned’s capital stock, partnership interests, membership interests or other similar equity interests, as the case may be, or all or substantially all of the undersigned’s assets, in any such case not undertaken for the purpose of avoiding the restrictions imposed by this agreement or (ii) to another corporation, partnership, limited liability company or other business entity so long as the transferee is an affiliate of the undersigned and such transfer is not for value. In addition, the undersigned agrees that during the Lock-Up Period, without the prior written consent of the Representatives, it will not make any demand for or exercise any right with respect to the registration of any Shares or any security convertible into or exercisable or exchangeable for Shares. The undersigned also agrees and consents to the entry of stop transfer instructions with the Company’s transfer agent and registrar against the transfer of the undersigned’s Shares except in compliance with this Agreement.

A-1

No provision in this agreement shall be deemed to restrict or prohibit the exercise or exchange by the undersigned of any option or warrant to acquire Shares, or securities exchangeable or exercisable for or convertible into Shares; provided that, the undersigned does not transfer the Shares acquired on such exercise or exchange during the Lock-Up Period, unless otherwise permitted pursuant to the terms of this letter agreement. In addition, no provision herein shall be deemed to restrict or prohibit the entry into or modification of a so-called “10b5-1” plan at any time (other than the entry into or modification of such a plan in such a manner as to cause the sale of any Shares or any securities convertible into or exercisable or exchangeable for Shares within the Lock-Up Period).

The undersigned understands that the Company and the Representatives are relying upon this letter agreement in proceeding toward consummation of the Public Offering. The undersigned further understands that this agreement is irrevocable and shall be binding upon the undersigned’s heirs, legal representatives, successors and assigns.

The undersigned understands that, if the Underwriting Agreement is not executed by ____________, or if the Underwriting Agreement (other than the provisions thereof which survive termination) shall terminate or be terminated prior to payment for and delivery of the Shares to be sold thereunder this agreement shall be void and of no further force or effect.

Whether or not the Public Offering actually occurs depends on a number of factors, including market conditions. Any Public Offering will only be made pursuant to an Underwriting Agreement, the terms of which are subject to negotiation between the Company and the Representatives.

	Very truly yours,
