1.2 The Employer employs the Executive, and the Executive accepts such employment, for a three year period commencing on the Effective Date

 2.2 Executive agrees to serve the Employer
faithfully and to the best of the Executive’s ability and to devote substantially all of the Executive’s business time, attention and efforts to the interests and business of the Employer.

3.1 Completion Bonus. On the Completion Date, with said Completion Date being on or before 90 days from the Effective Date,
Employer shall pay to Executive a one time cash bonus in the amount of $2,000,000.00 (the “Completion Bonus”). In the event that the Executive voluntarily resigns from his position with the Employer or the Employer terminates the
employment of the Executive and this Agreement for Cause (as defined below) on or before the second anniversary of the Effective Date, the Executive shall repay the Completion Bonus (in immediately available funds) to the Employer within two
business days following the date of such termination of employment. 
 3.2 Stock Grant. On the Effective Date, IBG shall grant
and issue to the Executive 60,000 restricted shares of its common stock. The grant and issuance of the restricted shares provided for in this Section 3.2 is subject to the terms and conditions of IBG’s 2013 Equity Incentive Plan (the
“Plan”), a copy of which has been provided to the Executive. Such grant of restricted shares shall be pursuant to, and evidenced by, a Restricted Stock Agreement as provided for in the Plan (the “Restricted Stock
Agreement”). 
 3.3 Salary. During the period from the Effective Date through the Term of this Agreement, the Employer shall
pay to Executive an annual base salary of $400,000.00 (the “Base Salary Amount”) in equal installments pursuant to the Employer’s standard payroll policies and subject to such withholding or deductions as may be mutually agreed
between the Employer and the Executive or required by law. Employer shall review Executive’s salary at the beginning of each calendar year but in no event shall the Base Salary Amount be reduced below $400,000.00. 

3.4 Annual Incentive Bonus. In addition to the Base Salary Amount, the Executive shall be eligible to receive an annual
incentive bonus, based upon the Executive’s and the Employer’s attainment of pre-established performance goals (the “Annual Incentive Bonus”). The performance goals upon which the Annual Incentive Bonus will be based shall
be adopted at the beginning of each year by the Board of Directors of the Employer (the “Board”). For each fiscal year during the Term of this Agreement, the Executive’s Annual Incentive Bonus amount shall be determined and

Incentive Bonus amount shall be completed no later than the 30th day after the end of each of the Employer’s fiscal year and shall be paid to the Executive within thirty (30) days after the amount has been approved by the Board. The Annual
Incentive Bonus shall be paid 65% in cash and 35% in restricted shares of IBG’s common stock granted pursuant to the Plan and a Restricted Stock Agreement as provided for in the Plan.

 3.5 Fringe Benefits. During the period of his employment, Executive shall be entitled to
participate in the Employer’s (i) group health plan, (ii) group disability insurance plan, (iii) life insurance benefits, (iv) 401(k) plan benefits, and (v) other benefits consistent with those provided by Employer to
other officers of similar positions with the Employer, including a car allowance, country club dues, cell phone allowance, etc. Executive will be entitled to four weeks of paid time off each year; no more than two consecutive weeks may be taken at
any given time in each fiscal year. 
 3.6 Expenses. During the Term of this Agreement, the Employer authorizes Executive to incur
reasonable and necessary out-of-pocket business expenses in the course of performing his duties and rendering services hereunder in accordance with Employer’s policies with respect thereto, and the Employer shall reimburse Executive for all
such expenses, provided (i) such expenses and the purpose for which they were incurred are in accordance with Employer’s policies, and (ii) the Executive timely submits to the Employer expense reports and substantiation of the
expenses in accordance with Employer’s policies. In such event, any such reimbursement shall be made as soon as practicable and in no event later than the end of the calendar month following the calendar month in which the expenses were
incurred and submitted for reimbursement. 
 3.7 280G Parachute Payments. Notwithstanding any other provision in this Agreement, if
(x) all or a portion of the Completion Bonus and the Restricted Stock Award to which the Executive is otherwise entitled to receive pursuant to Section 3.1 and Section 3.2 would constitute “parachute payments” as defined in
Section 280G(b)(2) of the Code with respect to the change in the ownership or effective control of BOHI as mutually determined by the Employer and Executive, and (y) the aggregate present value of such parachute payments and all other
parachute payments received by the Executive in connection with the Merger (taking into account the exclusion of the portion of any such payments that constitutes reasonable compensation for services to be rendered by the Executive on or after the
date of the Merger) is equal to or more than 3 times the Executive’s “base amount” as defined in Section 280G(b)(3) of the Code as mutually determined by the Employer and Executive, then the Completion Bonus and the Restricted
Stock Award will be reduced to an amount that, when combined with all other parachute payments received by the Executive in connection with the Merger (including parachute payments from BOHI), is equal to 2.99 times the Executive’s base amount.
In such case, the order of reduction pursuant to this Section shall apply first to the Completion Bonus until the portion of the Completion Bonus that constitutes parachute payment is reduced to zero, and then to the Restricted Stock Award to be
made last (i.e., in reverse order of time). 
 4.Termination. This Agreement shall terminate upon the death or disability of the Executive, the
voluntary resignation by the Executive, and the termination of employment by the Employer. The following sets forth the Employer’s obligations to the Executive upon each of these events. 

4.1 Termination Upon Death. Upon death of the Executive during the Term, the Employer shall pay to the Executive’s estate a lump
sum payment representing all compensation and benefits earned by the Executive and unpaid at the date of termination. Upon such payment, the Employer shall have no further obligation to the Executive or his estate under this Agreement. 

  
 3

required to make any payment to the Executive hereunder if such payment would be a “golden parachute payment” as defined in 12 CFR § 359 unless such payment can be made in compliance with such regulation. 

8.10 Injunctive Relief. In the event that Employer, IBG and/or the Executive violate any of the provisions set forth in this Agreement,
Employer, IBG, and the Executive acknowledge that the injured party would suffer immediate and irreparable harm and would not have an adequate remedy at law for money damages in the event that any of the covenants contained herein were not performed
in accordance with their terms or otherwise were materially breached. Accordingly, Employer, IBG, and the Executive agree that, without the necessity of proving actual damages or posting bond or other security, the parties hereto shall be entitled
to temporary or permanent injunction or injunctions to prevent breaches of such performance and to specific enforcement of such covenants in addition to any other remedy to which a party may be entitled, at law or in equity. In such a situation, the
parties agree that the injured party may pursue any remedy available, including declaratory relief, concurrently or consecutively in any order as to any breach, violation, or threatened breach or violation of this Agreement, and the pursuit of any
particular remedy or remedies shall not be deemed an election of remedies or waiver of the right to pursue any other remedy.

jurisdiction, the Participant or this Restricted Stock Agreement, and the remainder of this Restricted Stock Agreement shall remain in full force and effect.
