2010 Stock Incentive Plan (the “2010 Plan”) provides
for the grant of equity incentive awards to employees, directors
and consultants of Opexa in the form of incentive stock options or
nonqualified stock options, as well as restricted stock, stock
appreciation rights, restricted stock units and performance awards
that may be settled in cash, stock or other
property.  The 2010 Plan is the successor to and
continuation of Opexa’s June 2004 Compensatory Stock Option
Plan (the “2004 Plan”). A total of 625,000 shares of
common stock are authorized to be issued for awards made under the
2010 Plan through September 2020, plus (i) the number of shares
subject to stock options outstanding under the 2004 Plan that are
forfeited or terminate prior to exercise and would otherwise be
returned to the share reserves under the 2004 Plan and (ii) any
reserved shares under the 2004 Plan that were not issued or subject
to outstanding grants.  In addition, shares subject to
awards granted under the 2010 Plan that terminate or expire before
being exercised or settled will become available for grant under
the 2010 Plan. As of June 30, 2013, options to purchase an
aggregate of 1,089,500 shares were issued and
outstanding.</font></div>

connection with the January 2013 Notes, investors were issued

243,750 shares of common stock, at an exercise price of $1.24

warrants was $195,969 and was calculated using the Black-Scholes
valuation model. The following assumptions were used: (1) no
expected dividends, (2) risk free interest rate of 0.76%,
(3) expected volatility of 191% and (4) expected life of
five years. Opexa can redeem the warrants at $0.01 per share if the

to a waiver executed by the holders of in excess of two-thirds

Notes and accepted by Opexa, the amount of the cash subject to the

2013.  In exchange for such waiver, the Company issued
warrants to the holders of the July 2012 Notes to purchase an
aggregate of 187,500 shares of the Company’s common
stock.  The warrants have an exercise price of $1.21
per share and a five-year term.  The estimated fair value
of the warrants was $219,553 and was calculated using the
Black-Scholes valuation model.  The following assumptions
were used: (1) no expected dividends, (2) risk free interest rate
of 0.90%, (3) expected volatility of 191% and (4) expected life of
five years.  Opexa can redeem the warrants at $0.01 per
underlying share of common stock if the common stock closes at or
above $10.00 per share for 20 consecutive trading
days.  The fair value of the warrants was recognized as
additional interest expense during the six months ended June 30,
