1. Officer Termination Date. Executive acknowledges and agrees that his status as an officer of the Company will end effective as of a
date between March 10, 2016 and March 15, 2016 determined by the Company in consultation with Executive (such determined date, the “Officer Termination Date”). Executive hereby agrees to execute such further document(s) as shall be
determined by the Company as necessary or desirable to give effect to the termination of Executive’s status as an officer of the Company and each of its subsidiaries; including a written resignation substantially in the form of Appendix A to

Company hereby agrees, subject to this Agreement becoming effective and irrevocable and Executive’s performance of his continuing obligations pursuant to this Agreement and the Continuing Obligations, to provide Executive the severance benefits
set forth below. Specifically, the Company and Executive agree as follows: 
 (a) Base Salary. From the period

base salary (such that Executive shall be eligible to be paid the aggregate amount of $457,500, which constitutes eighteen (18) months’ of Executive’s base salary), less applicable withholdings and deductions. Such continued payments of
the base salary shall be made in bi-weekly installments in accordance with the standard payroll procedures of the Company. Such payments will be contingent upon this Agreement becoming irrevocable as provided herein and upon Executive’s
continued performance of all obligations under this Agreement. 
 (b) Healthcare Continuation Coverage. If Executive
timely elects to receive continued healthcare coverage pursuant to the provisions of the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended (“COBRA”), the Company shall directly pay, or reimburse Executive for, the
COBRA premiums for Executive and Executive’s covered dependents through the earlier of (i) the last day of the month during which the Severance Period ends or (ii) the date on which Executive and/or Executive’s covered dependents, if any,
become eligible for healthcare coverage under another employer’s plan(s); provided, that after the Company ceases to directly pay or reimburse premiums pursuant to the preceding, Executive may, if eligible, elect to continue healthcare
coverage at Executive’s expense in accordance with the provisions of COBRA. After the Company ceases to reimburse premiums pursuant to the preceding sentence, Executive may, if eligible, elect to continue healthcare coverage at Executive’s
expense in accordance with the provisions of COBRA. Executive acknowledges that he shall be solely responsible for all matters relating to Executive’s continuation of coverage pursuant to COBRA, including, without limitation, Executive’s
election of such coverage, provided, that the Company shall be responsible for the timely payment of premiums once such a time election is made. 

(c) 2016 Pro-rated Bonus. Executive shall be entitled to receive a pro-rated 2016 annual target incentive bonus
determined using the financial performance of the Company in 2016 assuming 100% achievement of any individual performance goals. The 2016 annual target incentive bonus shall be pro-rated based upon the actual number of days Executive was employed
during 2016. Any pro rata bonus that becomes payable pursuant to this paragraph shall be paid at the same time 2016 annual target incentive bonuses are paid to continuing senior executives of the Company. Such payment will be contingent upon
this Agreement becoming irrevocable as provided herein and upon Executive’s continued performance of all obligations under this Agreement. 

(d) Additional Bonus. Executive shall be entitled to receive as severance an additional bonus in the amount of $343,125
(which constitutes 150% of Executives 2016 annual target incentive bonus), less applicable withholdings and deductions. Such additional bonus payment shall be made in substantially equal bi-weekly installments during the Severance Period in
accordance with the standard payroll procedures of the Company. Such payments will be contingent upon this Agreement becoming irrevocable as provided herein and upon Executive’s continued performance of all obligations under this Agreement.

 (e) Transaction Bonus. In the event that Fujian Thai Hot Investment
Co., Ltd. completes its purchase of approximately 5,537,945 shares of Company common stock (the “Stock Purchase”) on or prior to December 31, 2016, then Executive will be entitled to receive a transaction bonus in the amount of
$150,000, less applicable withholdings and deductions, pursuant to the terms of a transaction bonus plan (the “Transaction Bonus Plan”) to be adopted by the Company in connection with the Stock Purchase. It is anticipated that
the Transaction Bonus Plan will provide for payment to be made in substantially equal installments on each of the closing of the Stock Purchase, the three month anniversary of such closing and the six month anniversary of such closing. 

(f) Discretionary Payment. During the Severance Period, Executive shall be entitled to receive continued payments of
$350.00 (the “Discretionary Payment”). Such continued payments of the Discretionary Payment shall be made in bi-weekly installments in accordance with the Company’s standard payroll procedures. Such payments will be contingent
upon this Agreement becoming irrevocable as provided herein and upon Executive’s continued performance of all obligations under this Agreement. 

(g) Outplacement Services. The Company shall reimburse Executive’s actual costs up to $35,000 for an outplacement
firm of the Company’s choosing related to Executive’s search for new employment. Executive must begin and conclude Executive’s participation with such outplacement firm no later than eighteen (18) months after the Employment Period
End Date or at such time that Executive secures other full time employment, whichever is earlier. In addition, fees for outplacement services will be paid directly to the applicable agency by the Company. All outplacement services and expenses must
be reviewed and approved by the Company prior to payment. 
 (h) Taxes. Executive understands and agrees that all
payments under this Agreement will be subject to appropriate tax withholding and other deductions. To the extent any taxes may be payable by Executive for the benefits provided to him by this Agreement beyond those withheld by the Company, Executive
agrees to pay them himself and to indemnify and hold the Company and the other entities released herein harmless for any tax claims or penalties, and associated attorneys’ fees and costs, resulting from any failure by him to make required
payments. To the extent that any reimbursements payable pursuant to this Agreement are subject to the provisions of Section 409A of the Code, such reimbursements shall be paid to Executive no later than December 31 of the year following the year in
which the expense was incurred, the amount of expenses reimbursed in one year shall not affect the amount eligible for reimbursement in any subsequent year, and Executive’s right to reimbursement under this Agreement will not be subject to
liquidation or exchange for another benefit. 
 (i) Sole Separation Benefit. Executive agrees that the payments
provided by this Section 4 are not required under the Company’s normal policies and procedures and are provided as a severance solely in connection with this Agreement. Executive acknowledges and agrees that the payments referenced in this
Section 4 constitute adequate and valuable consideration, in and of themselves, for the promises contained in this Agreement. 
 5. Full
Payment. Executive acknowledges that the payment and arrangements herein shall constitute full and complete satisfaction of any and all amounts properly due and owing to Executive as a result of his employment with the Company and the
