Basis of Presentation

Note 1. Basis of Presentation

The accompanying unaudited interim financial statements of Opexa Therapeutics, Inc. (“Opexa”), a development stage company, have been prepared in accordance with accounting principles generally accepted in the United States of America and the rules of the Securities and Exchange Commission and should be read in conjunction with the audited financial statements and notes thereto contained in Opexa’s latest Annual Report on Form 10-K filed with the SEC. In the opinion of management, all adjustments, consisting of normal recurring adjustments, necessary for a fair presentation of financial position and the results of operations for the interim periods presented have been reflected herein. The results of operations for interim periods are not necessarily indicative of the results to be expected for the full year. Notes to the financial statements that would substantially duplicate the disclosure contained in the audited financial statements for the most recent fiscal year as reported in Form 10-K, have been omitted.

Recently Issued Accounting Pronouncements

From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board (FASB) or other standard setting bodies that are adopted by Opexa as of the specified effective date. Unless otherwise discussed, Opexa believes that the impact of recently issued accounting pronouncements that are not yet effective will not have a material impact on their financial position or results of operations upon adoption.

Cash and Cash Equivalents

Note 2. Cash and Cash Equivalents

Opexa considers all highly liquid investments with an original maturity of three months or less, when purchased, to be cash equivalents. Investments with maturities in excess of three months but less than one year are classified as short-term investments and are stated at fair market value.

At June 30, 2011, Opexa invested approximately $9.7 million in a money market fund investing exclusively in high-quality, short-term money market instruments consisting of U.S. government obligations and repurchase agreements collateralized by the U.S. Government. While this fund seeks current income while preserving capital and liquidity, the fund is subject to risk, including U.S. government obligations risk. For the six months ended June 30, 2011, the money market fund recognized an average market yield of 0.01%. Interest income of $471 was recognized for the six months ended June 30, 2011 in the statements of expenses.

Commitments and Contingencies

Note 3. Commitments and Contingencies

Stem Cell Technology Agreement

In 2009, Novartis Pharmaceuticals acquired Opexa’s stem cell technology platform, which had been in early preclinical development, and took over all future responsibilities and opportunities for this technology, although Opexa retains an option on certain manufacturing rights. As part of the transaction, Opexa was paid an upfront fee of $3 million and a milestone payment of $500,000 for certain technology transfer activities. Opexa remains eligible to receive a second technology transfer milestone fee in addition to potential clinical and commercial milestones and royalty payments from the sale of any products resulting from the use of the technology. However, there can be no assurance that Opexa will receive any future payments in respect of the stem cell technology.

Equity

Note 4. Equity

In January 2011, Opexa sold an aggregate of 384,759 shares of common stock under the Continuous Offering Program Agreement dated May 14, 2010 (the “ATM Agreement”) for net proceeds of $1,033,994. Opexa paid compensation and fees totaling $10,826 to the placement agent with respect to the shares sold. The ATM Agreement was subsequently terminated by Opexa on February 7, 2011.

In February 2011, Opexa sold an aggregate of 4,146,500 units in a public offering, with each unit consisting of one share of common stock and a warrant to purchase four-tenths (0.40) of a share of common stock, at a price to the public of $2.05 per unit, for gross proceeds of $8,500,325. The shares of common stock and warrants were immediately separable and were issued separately such that no units were issued. The warrants were exercisable immediately upon issuance, having a five-year term and an exercise price of $2.61 per share. The warrants have a fair value of $3,236,584 that was calculated using the Black-Scholes valuation model using the following assumptions: (1) discount rate of 2.38%, (2) term of 5 years, (3) expected volatility of 197.60% and (4) zero expected dividends. The net proceeds to Opexa from this offering were approximately $7,584,163, after deducting underwriting discounts and commissions and other offering expenses. The offering closed on February 11, 2011.

Stock-Based Compensation

Note 5. Stock-Based Compensation

Restricted Shares

Pursuant to an agreement with a consultant for professional services, Opexa granted 50,305 restricted shares of common stock which were accounted for on March 19, 2011 pursuant to the relevant accounting rules. These shares vested immediately and were issued on April 8, 2011 and have a fair value of $87,028 based on the share price at the grant date, which was recognized as share-based compensation expense for the six months ended June 30, 2011.

Stock Options

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 either 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 2,500,000 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, 2011, options to purchase an aggregate of 1,739,072 shares were issued and outstanding.

Opexa accounts for share-based compensation, including options and nonvested shares, according to the provisions of FASB ASC 718, "Share Based Payment.” During the six months ended June 30, 2011, Opexa recognized share-based compensation expense of $291,873. Unamortized stock compensation expense as of June 30, 2011 amounted to $549,350.
