Compensation Summary



Compensation Philosophy and Objectives



Our philosophy in establishing
executive compensation policies and practices is to align each element of compensation with our short-term and long-term strategic
objectives, while providing competitive compensation that enables us to attract and retain top-quality executive talent



The primary objectives
of our compensation policies and practices for our named executive officers for the fiscal years ended June 30, 2017 and June 30,
2016 are to:



| | · | Attract, retain, motivate and reward highly qualified and competent executives who have extensive
industry experience through a mix of base salary, cash incentives and long-term equity incentives that recognize individual and
company performance; and
| | - | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | · | Provide incentives to increase and maximize stockholder value by emphasizing equity-based compensation
to more closely align the interests of executives with those of our stockholders.
| | - | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



5






We have adopted this
philosophy because we believe that it is critical to our continued success and the achievement of our short-term and long-term
goals and objectives as a company for our stockholders.



Administration



Our executive compensation
program is administered by the Compensation Committee in accordance with its charter and other corporate governance requirements
of the SEC and The NASDAQ Stock Market.



The Compensation Committee
has in the past engaged, and may in the future engage, compensation consultants familiar with our industry to advise the Compensation
Committee regarding certain compensation issues. The assignments of the consultants are determined by the Compensation Committee,
although management may have input into these assignments. In August 2015, the Compensation Committee retained Meridian Compensation
Partners LLC as its independent compensation consultant to assist and advise the Compensation Committee with respect to determinations
of future director compensation. The firm was selected by the Committee based on its reputation and expertise. In connection with
the appointment of MCP as the Compensation Committee’s compensation consultant, the Compensation Committee determined that
MCP was independent based on criteria prescribed by the NASDAQ Listing Rules. MCP reports directly to, and takes its direction
from, the Compensation Committee. However, the Compensation Committee does not specifically direct MCP on how to perform its scope
of services. MCP assisted the Compensation Committee by providing updates on relevant trends and developments in director compensation;
assessing the company’s peer group and the competitiveness of pay levels and practices for directors; and reviewing the compensation
of non-employee directors.



The Compensation Committee
determines the total compensation (including the nature and amount of each element of the compensation) of Ms. Fair (and prior
to February 2016, Mr. Rigdon), as our President and Chief Executive Officer. Ms. Fair (and prior to February 2016, Mr. Rigdon)
plays a key role in determining executive compensation for the other officers. Ms. Fair (and prior to February 2016, Mr. Rigdon)
attends the meetings of the Compensation Committee regarding executive compensation and discusses her recommendations with the
Compensation Committee, including the evaluation of the performance of the other named executive officers in arriving at her recommendations,
which are based on the direct evaluation of such executives by our President and Chief Executive Officer, after receiving input
from the peers of such executives and others, if necessary. These recommendations are considered by the Compensation Committee,
along with other relevant data, in determining the total compensation program for such executives.



Compensation Program



Based on and consistent
with the philosophy and objectives stated above, our current executive compensation program and its historical programs and practices
consist of the following elements:



·Base salary;



·Cash incentive awards;



·Long-term equity incentive awards;



·Post-employment benefits; and



·Benefits and perquisites.



We have chosen these
elements to remain competitive in attracting and retaining executive talent and to provide strong incentives for consistent high
performance with current and potential financial rewards. The compensation packages of the named executive officers are intended
to be evenly balanced among the various elements. The goal of this policy was and continues to be to attract and retain the executives
to ensure our long-term success. We also provide employee benefits such as health, dental and life insurance pursuant to plans
that are generally available to our employees. We think our mix of compensation instills in our executives the importance of achieving
our short-term and long-term business goals and objectives and thereby increasing stockholder value.



Consistent with our
total executive compensation philosophy set forth above, in setting executive compensation the Compensation Committee considers
the total compensation payable to a named executive officer and each form of compensation. The Compensation Committee seeks to
achieve a balance between immediate cash rewards for the achievement of company-wide objectives and individual objectives, and
long-term incentives that vest over time and that are designed to align the interests of our named executive officers with those
of our stockholders.

Additional details
regarding each element of our executive compensation program are as follows:



Base Salaries.
The base salary range for the named executive officers was established by the Compensation Committee. Base salary is viewed as
a less significant element of compensation than long-term equity, so the levels are less than those of peer companies. The Compensation
Committee approves all increases in base salary for our named executive officers in advance. The Compensation Committee reviews
salaries of executive officers at periodic intervals and awards increases, if appropriate. In assessing the amount and timing of
salary adjustments, if any, the Compensation Committee considers changes in functions and responsibilities, if any, competitive
salaries and peer comparisons, and relative employment positions. The Compensation Committee may also consider elements of individual
performance in future salary adjustments, but to this point, has not done so. Base salaries for all named executive officers for
the fiscal years ended June 30, 2015, 2016 and 2017, as applicable, are shown in the “Salary” column of the Summary
Compensation Table above.



Cash Incentive Compensation.
The named executive officers are each eligible for consideration for cash incentive compensation awards under the terms of their
employment agreements as described under “—Employment Agreements” below, within the discretion of the Compensation
Committee, which is common among the peer group noted above. The awards are intended to link cash incentive compensation to achievement
of our short-term business objectives and stockholders’ interests as a whole and would be based on objective performance
measures, thresholds and goals. In March 2017, Ms. Fair received a performance based bonus of $30,750. No performance based bonuses
were paid during fiscal years 2016 or 2015 were paid to named executive officers.



Long-Term Equity
Incentive Compensation. The Compensation Committee provides stock or equity incentives and rewards to executive officers in
order to link the executive’s long-term interests to those of our stockholders and to encourage stock ownership by executives
as a means of aligning the executives’ long-term interests with those of our stockholders. The analysis of awards by the
Compensation Committee is based upon an overall review of the performance of us and our management and the Compensation Committee’s
assessment of the appropriate level of long-term equity incentive compensation. The Compensation Committee does not follow a specific
process or necessarily consider objective or the same factors when making its overall review of our performance.



The 2015 Plan is maintained
with the objectives of (i) attracting and retaining selected key employees, consultants and outside directors; (ii) encouraging
their commitment; (iii) motivating superior performance; (iv) facilitating attainment of ownership interests in us; (v) aligning
personal interests with those of our stockholders; and (vi) enabling grantees to share in our long-term growth and success.



The Compensation Committee
exercises its discretion in determining the mix between and among awards of incentive stock options, non-qualified stock options
and restricted stock. To date, the only incentive awards granted to the named executive officers by the Compensation Committee
have been stock options. The exercise price of stock options is based on the fair market value of a share of our common stock on
the date of grant, which, under the 2015 Plan, is the closing sales price on that date of a share of our common stock as reported
on The NASDAQ Stock Market.



Currently, stock options
granted under the 2015 Plan vest ratably on the first, second, third and fourth anniversaries of the grant date so that the options
are fully vested after four years, except that in limited circumstances, we have granted stock options vesting in four quarterly
installments over twelve months to our directors and granted stock options with modified vesting to executive officers who elected
to exchange base salary for incentive compensation. Stock option grants are available for exercise for ten years from the date
of grant. Since stock options are priced at fair market value on the date of grant, the options will only have value to the grantee
if the market price of our common stock increases after the grant of the option.



Post-Employment
Benefits. We have entered into employment agreements with our executive officers which provide for the payment of severance
and other post-termination benefits depending on the nature of the termination, including, in some cases, severance payments in
the event of a termination following a “change in control.” The Compensation Committee believes that the terms and
conditions of these agreements are reasonable and assist us in retaining the executive talent needed to achieve our objectives.
In particular, the agreements, in the event of a “change in control,” help executives focus their attention on the
performance of their duties in the best interests of the stockholders without being concerned about the consequences to them of
a change in control and help promote continuity of senior management. Information regarding the specific payments that are applicable
to each termination event, as well as the effect on unvested equity awards, is provided under the heading “—Potential
Payments Upon Termination or Change of Control” below.



Benefits and Executive
Perquisites. As our executives and employees, the named executive officers are eligible to participate in the health, dental,
short-term disability and long-term disability insurance plans and programs provided to all company employees. Named executive
officers are also eligible to participate in our 401(k) plan, which is generally available to all of our employees.

Employment Agreements



On February 15, 2016,
we entered into an Amended and Restated Employment Agreement with Ms. Fair, which replaced her employment agreement dated
December 8, 2015. She is entitled to receive an annual base salary of up to $350,000 and a bonus targeted to $150,000 payable within
two and a half months after a given year based on achievement of certain annual performance goals and objectives approved by the
Compensation Committee. As part of the agreement Ms. Fair received stock options to acquire 300,000 shares of our common stock
vesting over four years in 25% increments on each anniversary date of the agreement. Ms. Fair is also eligible to receive additional
share based compensation awards at the sole discretion of the Compensation Committee. The employment agreement prohibits Ms. Fair
from competing with us during her employment and for a period of twenty-four months thereafter and is also prohibited from soliciting
our employees for a period of twenty-four months after the termination of her employment. Ms. Fair is also subject to confidentiality
and non-disparagement obligations. Payments under the agreement to Ms. Fair in connection with her termination or a change of control
are described below under “–Potential Payments Upon Termination or Change of Control.”



Effective May 9, 2017,
we entered into an employment letter with David Hiscocks our newly hired Corporate Controller and Corporate Secretary. Mr. Hiscocks’
employment is at-will and is terminable by either us or Mr. Hiscocks at any time with or without advanced notice. Mr. Hiscocks
is entitled to receive annual base compensation of $150,000. Mr. Hiscocks is also eligible for discretionary bonuses from time
to time in the Company’s sole discretion and based on achievement of individual and Company objectives. Mr. Hiscocks’
base compensation is subject to increase in the discretion of the Compensation Committee. The letter prohibits Mr. Hiscocks from
competing with us during his employment and for a period of six months thereafter and is also prohibited from soliciting our employees
for a period of six months after termination of his employment. Mr. Hiscocks received a grant of nonstatutory stock options to
acquire shares of the Company’s common stock with an aggregate value of $30,000 under the Plan, vesting as to 25% on each
anniversary of the date of the agreement. Mr. Hiscocks is also eligible to receive additional share based compensation awards at
the sole discretion of the Compensation Committee.



Effective January 3,
2017, we entered into an employment letter with Chris Raczkowski as our newly hired President – Asia. Under the employment
letter, he is entitled to receive an annual base salary of $139,000. Based on Mr. Raczkowski’s performance, the employment
letter contemplates the base salary can be increased to $200,000 after six months and $287,000 after twelve months. In June 2017,
his annual base salary was increased to $200,000. Upon signing the employment letter, Mr. Raczkowski received a $20,000 signing
bonus. He is also entitled to a performance bonus in the discretion of the Compensation Committee of the Board. Mr. Raczkowski’s
salary is subject to increase in the discretion of the Board. In connection with his appointment, Mr. Raczkowski also received
an award of an equivalent of $168,000 in options to acquire shares of the Company’s common stock vesting in four equal quarterly
installments with the first vesting occurring on March 31, 2017. The letter also includes non-competition, non-solicitation and
confidentiality covenants on Mr. Raczkowski. Mr. Raczkowski is also eligible for certain severance rights if he remains employed
on January 3, 2018.



Effective October 14,
2016, we entered into an amended employment letter with Scott Davis as our newly appointed Chief Accounting Officer, Corporate
Secretary, and Principal Financial Officer. Mr. Davis has previously served the Company as our Corporate Controller since May 2016.
Mr. Davis’ amended employment letter entitled him to receive an annual base salary of $200,000 and performance bonus at the
discretion of the Compensation Committee. In connection with his appointment, Mr. Davis also received a grant of restricted stock
to acquire 47,619 shares of our common stock vesting in four equal annual installments with the first vesting occurring on the
first anniversary of the date of the appointment. The amended letter also included non-competition, non-solicitation and confidentially
covenants on Mr. Davis. Mr. Davis announced his resignation from the Company effective May 22, 2017.



Potential Payments upon Termination
or Change of Control



Pursuant to the terms
of Ms. Fair’s employment agreement, upon a termination without cause (as defined in the employment agreement) or a voluntary
termination for good reason (as defined in the employment agreement), and provided that she executes a release, Ms. Fair is entitled
to receive (i) a severance payment of up to twelve months of base salary, (ii) continued health benefits through the earlier of
(a) twelve months after her termination or (b) until she is eligible to participate in the health insurance plan of another employer
(provided such benefits are substantially similar to what Ms. Fair received from us) and (iii) payment of any other salary or bonus
that she would have been otherwise entitled to receive under the employment agreement as of the date of the termination. In addition,
all unvested options shall automatically vest as of the termination date. If the employment agreement is terminated for any reason
(other than by Ms. Fair without good reason or by us for cause) within sixty days of a change of control (as defined in the employment
agreement), Ms. Fair is entitled to receive the same severance and benefits as she would receive if she was terminated without
cause by us.



Upon a voluntary termination
without good reason, termination for cause, death or disability, Ms. Fair would not be entitled to receive benefits from us except
that in the case of the death or disability of any of Ms. Fair, all unvested options shall automatically vest as of the termination
date.

The following tables
further describe the potential payments upon termination or a change in control for Ms. Fair. Because (i) Mr. Davis resigned effective
May 22, 2017, (ii) Mr. Hiscocks’ employment letter does not include provisions for payments in connection with a termination
or change of control, and (iii) the severance provisions in Mr. Raczkowski’s employment letter are not triggered until January
3, 2018, we do not present information on potential payments any of them.

________________

| | (1) | For purposes of this analysis, we assumed that the effective date of termination is June 30,
2017 and that the executive’s compensation is as follows: Ms Fair’s base salary is equal to $350,000. We have also
assumed no performance bonus for Ms. Fair due to the fact that the payment of such bonus is solely within the discretion of the
Compensation Committee and that there were no non-contractual performance bonuses paid during fiscal year 2017.
| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (2) | “After a Change in Control” means a termination for any reason (other than by us for
cause) within 60 days of a change in control.
| | --- | ----------------------------------------------------------------------------------------------------------------------------------



| | (3) | Under “Voluntary Termination for Good Reason,” “Involuntary Not for Cause Termination”
and “After a Change in Control,” severance under Ms. Fair’s agreement is one year of base salary as in effect
at the time of termination unless sooner hired by another employer.
| | --- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (4) | Pursuant to the terms of Ms. Fair’s employment agreement, under “Voluntary Termination
for Good Reason,” “Involuntary Not for Cause Termination” or “After a Change in Control”, the vesting
of all outstanding stock options will be accelerated and all stock options shall be 100% vested on the date of termination of employment
or on the effective date of the “change in control,” as applicable.
| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (7) | Health and Welfare Benefits Continuation is calculated as 12 months
of reimbursement of COBRA premiums under “Involuntary Not for Cause Termination,” “Voluntary Termination for
Good Reason” and “After a Change in Control.” Such benefits payable will cease prior to the end of 12 months
if the executive is eligible to participate in the health insurance plan of another employer, provided that such benefits
are substantially similar to what was received from us.

Director Compensation



In March 2017, the
Board approved compensation for calendar year 2017 for our directors. Non-executive directors who served as chair of a Board committee
received an annual grant of stock options with an aggregate value of $110,000 and all other non-executive directors received an
annual grant of stock options with an aggregate value of $100,000, in each case based on a fair market valuation and the exercise
price in the grant, while non-independent, executive directors received no compensation for their service on the Board. The options
vest as to 25% of the shares on each of March 31, June 30, September 30 and December 31 of 2017.
The exercise price was determined based on the closing price on the date of the grant. Mr. Lamadrid also was awarded $60,000 for
compensation as the Chairman of the Board with the cash compensation will be paid quarterly beginning with the quarter ended March
31, 2017.

Policy on Audit Committee Pre-Approval
of Audit and Non-Audit Services of Independent Registered Public Accountants



The Audit Committee’s
policy is to pre-approve all audit and non-audit services provided by the independent registered public accountants. These services
may include audit services, audit-related services, tax services and other services subject to the de minimis exceptions for non-audit
services described in Section 10A(i)(1)(B) of the Exchange Act which are approved by the Audit Committee prior to the completion
of the audit. Alternatively, the engagement of the independent registered public accountants may be entered into pursuant to pre-approval
policies and procedures established by the Audit Committee, provided that the policies and procedures are detailed as to the particular
services and the Audit Committee is informed of each service. The Audit Committee may form and delegate authority to subcommittees
consisting of one or more members when appropriate, including the authority to grant pre-approvals of audit and permitted non-audit
services, provided that decisions of such subcommittee to grant pre-approvals shall be presented to the full Audit Committee at
its next scheduled meeting.
