Series A warrants 3,550
Net proceeds $ 15,457 (c) Stock incentive plan The Company has
a stock incentive plan, the 2002 Stock Incentive Plan (the Stock Incentive Plan), under which up to 7,200,000 options
are available for grant to employees, directors and consultants. Options granted under the Stock Incentive Plan may be either incentive
stock options or non-statutory stock options. Under the terms of the Stock Incentive Plan, the exercise price per share for an
incentive stock option shall not be less than the fair market value of a share of stock on the effective date of grant and the
exercise price per share for non-statutory stock options shall not be less than 85% of the fair market value of a share of stock
on the date of grant. No option granted to a holder of more than 10% of the Companys common stock shall have an exercise
price per share less than 110% of the fair market value of a share of stock on the effective date of grant. Options granted
are typically service-based options. Generally, options expire 10 years after the date of grant. No incentive stock options granted
to a 10% owner optionee shall be exercisable after the expiration of five years after the effective date of grant of such option,
no option has been granted to a prospective employee, prospective consultant or prospective director prior to the date on which
such person commences service, and with the exception of an option granted to an officer, director or consultant, no incentive
option shall become exercisable at a rate less than 20% per annum over a period of five years from the effective date of grant
of such option unless otherwise approved by the Board. The Company accounts
for stock-based compensation under the authoritative guidance which requires that share-based payment transactions with employees
be recognized in the financial statements based on their fair value and recognized as compensation expense over the vesting period.
The amount of expense recognized during the period is affected by subjective assumptions, including: estimates of the Companys
future volatility, the expected term for its stock options, option exercise behavior, the number of options expected to ultimately
vest, and the timing of vesting for the Companys share-based awards. The following table
sets forth the total stock-based compensation expense resulting from stock options and the employee stock purchase plan included
in the Companys condensed consolidated statements of operations and comprehensive loss (in thousands):

as part of the second amendment to the Term Loan Agreement and funding of the $10,000 tranche, CRG received warrants to purchase
350,000 common shares in the Company at a price of $5.00 per share (the CRG Warrants). The CRG Warrants are exercisable
any time prior to October 8, 2020. The CRG Warrants are classified as equity on the Consolidated Balance Sheets as of December
31, 2015 and June 30, 2016. The CRG Warrants were valued at $290 upon issuance using the Black-Scholes Merton model assuming volatility
of 73%, an expected life of 5.0 years, a risk-free interest rate of 1.71%, and 0% dividend yield. No CRG Warrants were exercised
during the six months ended June 30, 2016. On April 8, 2016,
the Company further amended its Term Loan Agreement. As part of the amendment, the exercise price of the CRG Warrants was changed
to allow the holder to purchase 350,000 common shares in the Company at a price of $1.50 per share and CRG was issued an additional
350,000 warrants to purchase common shares at an exercise price of $1.50 (the 2016 CRG Warrants). The modification
to the terms of the CRG Warrants resulted in a change in fair value of $54 which was included as interest expense for the three
and six months ended June 30, 2016. The change in fair value was calculated using the Black-Scholes Merton model with both exercise
prices, assuming volatility of 76%, an expected life of 4.5 years, a risk-free interest rate of 1.06%, and 0% dividend yield. The
2016 CRG Warrants were valued at $106 upon issuance using the Black-Scholes Merton model assuming volatility of 76%, an expected
life of 5.0 years, a risk-free interest rate of 1.30% and 0% dividend yield. On May 9, 2016,
the Company issued Series A Warrants to purchase 11,500,000 shares of common stock for $1.125 per common share attached to shares
of common and Series A Convertible Preferred Stock issued on the same date. The Series A Warrants can be exercised after May 9,
2017 (the Initial Exercise Date) and expire 5 years after the Initial Exercise Date. Fair value of the Series A Warrants,
for purposes of allocating the net proceeds of the equity offering, was determined using the Black-Scholes Merton model assuming
volatility of 76%, an expected life of 6.0 years, a risk-free interest rate of 1.30%, and 0% dividend yield. (e) Exchange Right In August 2014,
the Company sold membership units in OcuHub LLC, a Delaware limited liability company, which was a wholly owned subsidiary of
