Compensation Program, a copy of a description of which has been furnished to you (the "Program Description.")
The shares and restricted stock units referred to in this Agreement are issued under the Company's Stock Incentive Plan, which
is incorporated into this Agreement by this reference. In the event of a conflict between the terms of this Agreement and the Program

Plan, and that you accept this award.



In consideration of the foregoing recitals
and the covenants made in this Agreement, you and the Company agree as follows:



| | 1. | The «First_Year» Long-Term Incentive Compensation Program. On «CC_Vote_Date»,
the Compensation Committee of the Board of Directors of the Company (the "Committee") approved your participation
in the «First_Year» Long-Term Incentive Compensation Program (the "2015 LTIP Program") which gives
you and other participants the opportunity to earn shares of common stock of the Company. References in this Agreement to "common
stock" mean the Company's common stock, $0.01 par value per share. The «First_Year» LTIP Program begins on January
1, «First_Year» and ends on December 31, «Last_Year». That period is referred to in this Agreement as the
"Program Cycle."
| | -- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 2. | Time-Based Shares. The Company hereby awards to you under the terms and conditions of this
Agreement «TB_Shares» shares of common stock. These shares are referred to in this Agreement as the "Time-Based
Shares."
| | -- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (a) | Restrictions on Transfer. You may not sell, assign, transfer, pledge or otherwise dispose of,
or encumber any of the Time-Based Shares, or any of your rights or interests in them except by your will, or according to the laws
of descent and distribution (the "Restrictions.")
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (b) | Vesting. If you are an employee of the Company on December 31, «Last_Year», the
Restrictions will expire, and the Time-Based Shares will vest. If you are not an employee on December 31, «Last_Year»,
your Time-Based Shares will be automatically forfeited except as otherwise provided below in Section 5 of this Agreement.
| | --- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (c) | Rights as a Stockholder. Subject to the Restrictions and the other limitations and conditions
set forth in this Agreement, while you are the owner of the Time-Based Shares, you will have all of the rights of a stockholder
of the Company, including the right to vote the shares.
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 3. | Restricted Stock Units.
| | -- | -----------------------



| | (a) | RSU's. The Company hereby also awards to you under the terms and conditions of this Agreement«RSUs» restricted stock units (the "Target RSU's.") Each of the Target RSU's is an unfunded and
unsecured, non-transferable promise, subject to the vesting and other terms and conditions of this Agreement, to issue to you one
share of common stock if the Target RSU vests.
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------










| | (b) | Restrictions on Transfer. The Target RSU's are subject to the same restrictions on transfer
as are described above in Section 2(a) for the Time-Based Shares.
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (c) | Vesting — Performance Levels.
| | --- | -----------------------------



| | (i) | Target RSU's are eligible to be converted into shares of common stock and to vest depending on the
ranking of the total shareholder return ("TSR") of the Company at the end of the Program Cycle compared to the
TSR at the end of the Program Cycle of each company listed in Appendix A to this Agreement (the "Peer Group.")
| | --- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (ii) | TSR is the percentage change in a company's stock price (plus dividends paid) over a period of time.
For the 2015 LTIP Program, it is the change in the Company's stock price over the course of the Program Cycle.
| | ---- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (iii) | For purposes of computing the Company's TSR, the beginning stock price will be the simple average
of the closing stock prices on the Nasdaq Stock Market during the month of December 2014 ($6.296) and the ending stock price will
be the simple average in December 2017.
| | ----- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (iv) | The following table shows possible percentage rankings of the Company's TSR and the corresponding
number, if any, of your Target RSU's that would vest. A ranking that falls between the ranking percentages in the table will be
determined by lineal interpolation. Any fractional share that results from the calculations will be rounded up to the next whole
share. As can be seen in the table, it is possible for more RSU's to vest than the number of your Target RSU's.
| | ---- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|The Company's TSR Percentile Ranking | Percentage of Target RSU's that Vest
|------------------------------------ | ------------------------------------
|80% or higher                        | 150%                                
|50%                                  | 100%                                
|25%                                  | 25%                                 
|Below 25%                            | 0%

the Program Cycle, will be multiplied by a fraction, the numerator of which is the number of whole calendar months in the Program
Cycle that you were an employee of the Company, and the denominator of which is 36. The resulting number of Time-Based Shares and
RSU's, if any, will vest at the end of the Program Cycle.

the Program Cycle equal to the taxes required to be withheld.
