Dear Ms. Hope Diaz:

I am pleased to extend this conditional offer of employment as Chief Marketing Officer with Fiesta Restaurant Group, Inc. {"Fiesta"), reporting to Rich Stockinger, President and Chief Executive Officer. Your new office will be located at 7255 Corporate Center Drive, Miami, Florida 33126. I propose a start date of September 14, 2019 and am excited to work with you.

The following is a brief outline of the major components of this conditional offer of employment:

Your annualized base salary will be $325,000. You will be paid biweekly.

You are eligible for a one-time special incentive bonus of $150,000 to be paid on or before March 15, 2020. In the event you voluntarily terminate from the Company other than for Good Reason (as defined in the Severance Agreement described below) within one year of the payment date of the sign on bonus, the sign on bonus must be refunded and you authorize the Company to deduct this obligation insofar as possible, from any salary, wages, accrued vacation, bonus or other payments or employee benefits to which you may be entitled or business expense reimbursement amounts that may be due to you. You agree that you remain liable for any amount that is not withheld from your wages. By signing this offer letter, you accept the terms of this agreement.

You are eligible for a one-time special incentive bonus of $375,000 to be paid over five (5) years in equal annual installments of $75,000 per year. The first payment will be on January 1, 2020. You will earn each installment 12 months after it is paid. In the event you voluntarily terminate from the Company prior to your final incentive payment you will forfeit any future payments and you will be required to refund any unearned payment to the Company. You authorize the Company to deduct this obligation insofar as possible, from any salary, wages, accrued vacation, bonus or other payments or employee benefits to which you may be entitled, or business expense reimbursement amounts that may be due to you. You agree that you remain liable for any amount that is not withheld from your wages. By signing this offer letter you accept the terms of this agreement.

Commencing in 2020, you will be eligible for annual equity grants of approximately $227,500, subject to the discretion of the Compensation Committee of the Board of Directors. The equity grants are currently expected to be comprised of 25% restricted stock awards, 25% stock options and 50% based on performance- based criteria to be determined prior to the date of grant.

Fiesta will enter into a separate agreement with you to provide certain severance payments upon termination of your employment by Fiesta without Cause and for reasons other than death or "permanent and total disability" (within the meaning Section 22(e)(3) of the Code) or by you voluntarily for Good Reason (to be defined in the agreement). The severance payments will include an amount equal to one

times your annual base salary in effect prior to the date employment is terminated and an amount equal to a pro rata portion of the aggregate bonus you would have been entitled to receive with respect to the fiscal year of termination had employment not been terminated. Such bonus shall be paid at the same time it would have been paid had your employment not been terminated.

Details regarding our comprehensive benefits package will be provided to you.

You are eligible for three weeks of vacation from date of hire through your ninth year. On your tenth year of employment, you will then be eligible for four weeks of vacation.
