<font style="FONT-FAMILY: Times New Roman" size="2">The 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 March 31, 2013,
options to purchase an aggregate of 903,289 shares were issued and
outstanding.</font></p>

with the January 2013 Notes (see Note 7), investors were issued
five-year warrants to purchase up to an aggregate of
243,750 shares of common stock, at an exercise price of $1.24

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

In exchange for such waiver, the Company issued warrants to the
holders of the July 2012 Notes to purchase an aggregate of 187,500

an exercise price of $1.21 per share and a five-year term. The

(2) risk free interest rate of 0.90%, (3) expected

<font style="FONT-FAMILY: Times New Roman" size="2">On
September 2, 2010, the Board adopted the Opexa Therapeutics,
Inc. 2010 Stock Incentive Plan (“the 2010 Plan”) for
the granting of equity incentive awards to employees, directors and
consultants of Opexa. The 2010 Plan was approved by the
Company’s stockholders on October 19, 2010. The 2010
Plan is the successor to and continuation of Opexa’s June
2004 Compensatory Stock Option Plan (the “2004 Plan”).
The 2004 Plan reserved a maximum of 575,000 shares of common stock
for issuance pursuant to incentive stock options and nonqualified
stock options granted to employees, directors and consultants.
Awards were made as either incentive stock options or nonqualified
stock options, with the Board having discretion to determine the
number, term, exercise price and vesting of grants made under the
2004 Plan. All outstanding equity awards granted under the 2004
Plan continue to be subject to the terms and conditions as set
forth in the agreements evidencing such stock awards and the terms
of the 2004 Plan, but no additional awards will be granted under
the 2004 Plan subsequent to approval of the 2010 Plan. Under the
2010 Plan, the total number of shares of common stock reserved for
issuance consists of 625,000 shares plus 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 any reserved
shares not issued or subject to outstanding grants, up to a maximum
of 793,204 shares. The 2010 Plan provides for the grant 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 Board of Directors or Compensation Committee, as
applicable, administers the 2010 Plan and has discretion to
determine the recipients, the number and types of stock awards to
be granted and the terms and conditions of the stock awards,
including the period of their exercisability and vesting. Subject
to a limitation on repricing without stockholder approval, the
Board or Compensation Committee, as applicable, may also determine
the exercise price of options granted under the 2010
Plan.</font></p>
