Re: Employment with Synthesis Energy Systems, Inc. (the “Company”)

Dear Charlie,

This letter agreement confirms the terms of your employment to you effective September 3, 2013 (the “Effective Date”).

Title/Reporting Relationship

Your title is Chief Financial Officer and you report to the Company’s chief executive officer (the “CEO”).

Responsibilities

Your duties and responsibilities will be such as are reasonably assigned to you by the CEO. While employed by the Company, you will devote full time and attention during normal business hours to the affairs of the Company and use your best efforts to perform faithfully and efficiently your duties and responsibilities. You shall perform the services required by this letter agreement at the Company’s present principal place of business or at such other location(s) as may be mutually agreed by you and the Company; provided, however, that your responsibilities for the Company will require you to conduct temporary travel to other domestic and international locations (including without limitation countries in Asia and Europe) on business for the Company consistent with the business needs of the Company.

Compensation

Your base compensation will be $300,000 per year (the “Base Compensation”), $200,000 of which (the “Base Salary”) shall be payable in cash in equal semi-monthly installments of $8,333.33 or in accordance with the Company’s established policy, subject such payroll and withholding deductions as may be required by law and other deductions (consistent with the Company’s policy for all employees) relating to your election to participate in the Company’s incentive, savings, retirement and other employee benefit plans.

During the first twelve months of your employment (the “Initial Year”), the Company will grant you nonstatutory stock options subject to an agreement (an “Option Agreement”) to be entered into between the Company and you (with the approval of the Compensation Committee of the Company’s Board of the Directors (the “Board”)). The Company’s grant to you of nonstatutory stock options will be options to acquire whole shares of the Company’s common stock having a fair market value of $100,000 on the date of grant as determined under the Company’s Amended and Restated 2005 Incentive Plan, as amended (the “Plan”), vesting as to 25% on the date of grant and the remainder vesting in equal amounts quarterly over the subsequent twelve months. The nonstatutory stock options will be subject to the terms and conditions of the NSOA and the Plan.

For each twelve month period subsequent to the Initial Year, $100,000 of your Base Compensation shall either be paid in cash (and increasing the bi-monthly Base Salary from $8,333.33 to $12,500.00) or in lieu thereof shall be in the form of nonstatutory stock options, and subject to the terms and conditions, of an Option Agreement to be entered into between the Company and you (with the approval of the Compensation Committee of the Board), which shall reflect a number of shares of common stock of the Company with a fair market value of $100,000 on the date of grant as determined under the Plan. The determination of whether such amount shall be paid in cash or nonstatutory stock options shall be determined by the mutual agreement of you and the Compensation Committee of the Board fifteen (15) days prior to the expiration of the Initial Year and each succeeding twelve month period thereafter.

In addition, the Company will conduct an annual review of your compensation and may, in its sole discretion, increase the Base Compensation based upon relevant circumstances.

Vacation

During the term of your employment, you shall be entitled to annual paid vacation equal to twenty days during each one-year period commencing on the Effective Date. The use of any vacation time not taken during the applicable one-year period will be subject to the Company’s vacation policy as in effect from time to time.

Bonus Program

You will be eligible, as to each fiscal year until the termination of your employment, for an annual performance bonus (the “Annual Bonus”), with the amount and payment of such bonus to be determined by, and to be at the sole discretion of, the CEO, with approval of the Compensation Committee of the Board. The bonus amount will be based on achievement of certain annual Company and individual goals and objectives. Such bonus will be paid by no later than the later of 2 ½ months after the end of the calendar year in which it is earned or 2 ½ months after the end of the Company’s tax year in which it is earned. For the purposes of this Agreement, the term “Annual Bonus” will refer only to the cash bonus, and not to long-term equity incentives to be paid pursuant to any compensation plan then in effect.

Incentive Award

Subject to the terms and conditions of a Nonstatutory Stock Option Agreement to be entered into between the Company and you (with the approval of the Compensation Committee of the Board), the Company shall grant to you nonstatutory stock options to acquire 200,000 shares of the Company’s common stock at the fair market value of such shares on the date of grant as determined under the Plan, vesting as to 25% on the date of grant and the remainder vesting 25% annually over three years from the effective date of the grant.

Plans

You shall be eligible to participate in and shall receive all benefits under all incentive, savings and retirement plans and programs maintained or established by the Company for the benefit of our employees. Further, you and/or your family, as the case may be, shall be eligible to participate in and shall receive all benefits under each welfare benefit plan of the Company maintained or established by the Company for the benefit of its employees. The Company shall not be obligated to institute, maintain, or refrain from changing, amending, or discontinuing, any such program or plan.

Reimbursement of Business Expenses

You may from time to time during the term of your employment incur various business expenses customarily incurred by persons holding positions of like responsibility, including, without limitation, travel expenses incurred for the benefit of the Company. Subject to complying with the Company’s policy regarding the reimbursement of such expenses as in effect from time to time during the term of your employment, which does not necessarily allow reimbursement of all such expenses, the Company shall reimburse you for such expenses from time to time, at your request, and you shall account to the Company for all such expenses. Such expenses will be reimbursed no later than the later of 2½ months after the end of the calendar year in which it is incurred or the 2½ months after the end of the Company’s tax year in which it is incurred.

In addition, the Company shall reimburse you up to $150 per month for expenses associated with a cellular phone to the extent used for business of the Company. Subject to complying with the Company’s policy regarding the reimbursement of expenses as in effect from time to time during the term of your employment and your accounting to the Company for such expenses, the Company shall provide such reimbursement on a monthly basis through the bi-weekly cash payments of Base Salary.

(a) any “person” (as defined in section 3(a)(9) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and as such term is modified in sections 13(d) and 14(d) of the Exchange Act), excluding the Company or any of its subsidiaries, a trustee or any fiduciary holding securities under an employee benefit plan of the Company or any of its subsidiaries, an underwriter temporarily holding securities pursuant to an offering of such securities or a corporation owned, directly or indirectly, by stockholders of the Company in substantially the same proportions as their ownership of the Company, is or becomes the “beneficial owner” (as defined in Rule 13d-3 under the Exchange Act), directly or indirectly, of securities of the Company representing 50% or more of the combined voting power of the Company’s then outstanding securities; or

(b) during any period of not more than two consecutive years, individuals who at the beginning of such period constitute the Board and any new director (other than a director designated by a person who has entered into an agreement with the Company to effect a transaction described in clause (a), (c) or (d) of this definition) whose election by the Board or nomination for election by the Company’s stockholders was approved by a vote of at least two-thirds (2/3) of the directors then still in office who either were directors at the beginning of the period or whose election or nomination for election was previously so approved, cease for any reason to constitute a majority thereof; or

(c) the stockholders of the Company approve a merger or consolidation of the Company with any other corporation, other than (i) a merger or consolidation which would result in the voting securities of the Company outstanding immediately prior thereto continuing to represent (either by remaining outstanding or by being converted into voting securities of the surviving entity), in combination with the ownership of any trustee or other fiduciary holder of securities under an employee benefit plan of the Company, at least 50% of the combined voting power of the voting securities of the Company or such surviving entity outstanding immediately after such merger or consolidation, or (ii) a merger or consolidation effected to implement a recapitalization of the Company (or similar transaction) in which no person acquires more than 50% of the combined voting power of the Company’s then outstanding securities; or

(d) the stockholders of the Company approve a plan of complete liquidation of the Company or an agreement for the sale or disposition by the Company of all or substantially all of the Company’s assets.

Notwithstanding the foregoing, no Change in Control shall be deemed to have occurred if there is consummated any transaction or series of integrated transactions immediately following which, in the judgment of the Compensation Committee of the Board, the holders of the Company’s common stock, immediately prior to such transaction or series of transactions, continue to have the same proportionate ownership in an entity which owns all or substantially all of the assets of the Company immediately prior to such transaction or series of transactions. The Board may (i) deem any other corporate event affecting the Company (other than those described in clauses (a)-(d) of this definition) to be a “Change in Control,” and (ii) may amend this definition of “Change in Control” in connection with an identical amendment being made to employment agreements entered into by the Company and all of its executive officers.

Any question as to the existence of a Disability as to which you and the Company cannot agree shall be determined in writing by a qualified independent physician mutually acceptable to you and the Company.

“Without Cause” means a termination for any reason other than for Cause or Disability or on account of your death.

Continuation of Benefits

Such payments shall be paid by the Company according to a fixed schedule consisting of monthly installment payments. The foregoing payments by the Company shall not extend the applicable COBRA continuation period and the COBRA continuation period shall commence as required under COBRA on account of your termination of employment.

Benefits otherwise receivable by you pursuant to this section shall be reduced to the extent substantially similar benefits are actually received by or made available to you by any other employer during the same time period for which such benefits would be provided pursuant to this section at a cost to you that is commensurate with the cost incurred by you immediately prior to the date of termination; provided, however, that if you become employed by a new employer which maintains a medical plan that either (i) does not cover you or a family member or dependent with respect to a preexisting condition which was covered under the applicable Company medical plan, or (ii) does not cover you or a family member or dependent for a designated waiting period, your coverage under the applicable Company medical plan shall continue (but shall be limited in the event of noncoverage due to a preexisting condition, to such preexisting condition) until the earlier of the end of the applicable period of noncoverage under the new employer’s plan or the six-month anniversary of the date of termination. You agree to report to the Company any coverage and benefits actually received by you or made available to you from such other employer(s). You shall be entitled to elect to change your level of coverage and/or your choice of coverage options (such as for you only or family medical coverage) with respect to the benefits to be provided by the Company to you to the same extent that active employees of the Company are permitted to make such changes; provided, however, that in the event of any such changes you shall pay the amount of any cost increase that would actually be paid by an active employees of the Company by reason of making the same change in his level of coverage or coverage options.

To the extent any amount payable under “Severance” or “Continuation of Benefits” is deferred compensation subject to Section 409A of Internal Revenue Code of 1986, as amended (the “Code”), if the period during which you have discretion to execute or revoke the general release of claims straddles two of your taxable years, then the Company shall make the severance payments starting in the second of such taxable years, regardless of which taxable year you actually deliver the executed general release of claims to the Company. You may not, directly or indirectly, designate the calendar year or timing of payments.
