RE:    Special Retention Award

Dear Jeff:

As we have discussed, in lieu of receiving a 2014 supplemental stock option
award and conditioned on your continued employment through the earlier of (a)
March 31, 2015 and (b) your employment termination by the Company not for Cause
or by you for Good Reason as defined in your Employment Agreement dated October
2, 2012 and amended January 8, 2013 (“Retention Date”), you are eligible for a
cash retention award in the amount of $100,000, before required withholdings, to
be paid as soon as reasonably practicable after the Retention Date.

Sincerely,
/s/ SANDRA PRICE
