1.     Operations and Organization
 
Operations
 
Rexahn Pharmaceuticals, Inc. (the “Company”, “Rexahn Pharmaceuticals”), a Delaware corporation, is a development stage biopharmaceutical company dedicated to the discovery, development and commercialization of innovative treatments for cancer and other medical needs.  The Company had an accumulated deficit of $67,950,138 at June 30, 2013 and anticipates incurring losses through the remainder of fiscal 2013 and beyond.  The Company has not yet generated commercial sales revenue and has been able to fund its operating losses to date through the sale of its common stock, warrants exercisable for common stock, issuance of long-term debt, and proceeds from reimbursed research and development costs.  The Company believes that its cash, cash equivalents, and marketable securities, including the proceeds received from the registered direct offering as described in Note 18, will be sufficient to cover its cash flow requirements into 2015.  Management has the capability of managing the Company’s operations within existing cash available by focusing on select research and development activities, selecting projects in conjunction with potential financings and milestones, and efficient management of its general and administrative affairs.
 
Basis of Presentation
 
The accompanying unaudited condensed financial statements of the Company have been prepared pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”) for interim financial information.  Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States for complete financial statements.  In the opinion of the Company’s management, all adjustments (consisting of only normal recurring accruals) considered necessary for a fair presentation of the Company’s financial position as of June 30, 2013 and December 31, 2012, the results of operations for the three and six months ended June 30, 2013 and 2012, and cash flows for the six months ended June 30, 2013 and 2012 have been included.  Operating results for the three and six months ended June 30, 2013 are not necessarily indicative of results that may be expected for any other interim period or the full fiscal year ending December 31, 2013. The accompanying unaudited financial statements should be read in conjunction with the audited financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2012 (“2012 Form 10-K”).  Information included in the condensed balance sheet as of December 31, 2012 has been derived from the Company’s audited financial statements for the year ended December 31, 2012 included in the 2012 Form 10-K.
 
Use of Estimates
 
The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period.  These estimates are based on management’s best knowledge of current events and actions the Company may undertake in the future.  Actual results may ultimately differ from those estimates.  These estimates are reviewed periodically and as adjustments become necessary, they are reported in earnings in the period in which they become available.

2.     Recent Accounting Pronouncement Affecting the Company

Comprehensive Income

In February, 2013 the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update 2013-02, “Comprehensive Income: Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income,” to improve the transparency of reporting reclassifications from comprehensive income to net income.  The new amendments require that a company must present the effects on line items of net income of significant amounts reclassified out of accumulated other comprehensive income, and additional referencing and disclosure regarding these items.  The guidance is effective for the Company for fiscal years and interim periods beginning on or after December 15, 2012.  The Company adopted this guidance during the quarter ended March 31, 2013.  There was no material impact on the Company’s financial statements due to the adoption of this guidance.

8.     Deferred Research and Development Arrangements
 
Rexgene Biotech Co., Ltd.
 
In 2003, the Company entered into a collaborative research agreement with Rexgene Biotech Co., Ltd. (“Rexgene”), a shareholder.  Rexgene is engaged in the development of pharmaceutical products in Asia and has agreed to assist the Company with the research, development and clinical trials necessary for registration of the Company’s drug candidate, Archexin, in Asia.  This agreement provides Rexgene with exclusive rights to license, sublicense, make, have made, use, sell and import Archexin in Asia.  In accordance with the agreement, Rexgene paid the Company a one-time fee of $1,500,000 in 2003.  The agreement terminates at the later of 20 years or the term of the patent.  The amortization reduces research and development expenses for the periods presented.

The Company is using 20 years as its basis for recognition and accordingly $18,750 and $37,500 reduced research and development expenses for the three and six months ended June 30, 2013 and 2012, respectively.  The remaining $712,500 and $750,000 at June 30, 2013 and December 31, 2012, respectively, is reflected as in deferred research and development arrangements on the balance sheet.  The contribution is being used in the cooperative funding of the costs of development of Archexin. Royalties of 3% of net sales of licensed products will become payable to the Company on a quarterly basis once commercial sales of Archexin begin in Asia.  The product is still under development and commercial sales in Asia are not expected to begin until at least 2014.  Under the terms of the agreement, Rexgene does not receive royalties on Company net sales outside of Asia.
 
Teva Pharmaceutical Industries, Ltd.
 
On September 21, 2009, the Company closed on a securities purchase agreement with Teva Pharmaceutical Industries Limited (“Teva”), under which Teva purchased 3,102,837 shares of our common stock for $3.5 million. Contemporaneous with the execution and delivery of this agreement, the parties executed a research and exclusive license option agreement (“RELO”) pursuant to which the Company agreed to use $2,000,000 from the gross proceeds of the issuance and sale of shares to Teva to fund a research and development program for the pre-clinical development of RX-3117.  On January 19, 2011, the Company entered into a second amendment to the securities purchase agreement in which Teva purchased 2,334,515 shares of the common stock of the company for gross proceeds of $3.95 million.  On November 27, 2012, the Company and Teva entered into a second amendment to the RELO agreement, pursuant to which Teva provided the Company with an additional $926,000 of research funding for the development of RX-3117, which was recorded as restricted cash on the Company’s balance sheet.  The contribution from the second amendment was recorded in deferred research and development arrangements on the balance sheet, and costs incurred for the development of RX-3117 are paid from restricted cash, and reduce the deferred research and development arrangement and therefore, are not an expense in the Company’s statement of operations.  As of June 30, 2013 and December 31, 2012, the Company had proceeds remaining of $531,379, and $876,000, respectively, which is included in deferred research and development arrangements on the balance sheet.  During the three and six months ended June 30, 2013, $210,000 and $344,621 was reduced from the deferred research and development arrangement for costs incurred for the development of RX-3117, respectively.

9.    Other Liabilities

Deferred Lease Incentive

On June 29, 2009, the Company entered into a five year office lease agreement as disclosed in Note 16.  The lessor agreed to grant a leasehold improvement allowance of $100,000 to the Company to be used for the construction cost of improvements to the leased property, which included architectural and engineering fees, government agency plan check, permit and other fees, sales and use taxes, testing and inspection costs, and telephone and data cabling and wiring in the premises.  The Company accounts for the benefit of the leasehold improvement allowance as a reduction of rental expense over the five-year term of the office lease.
 
The following table sets forth the deferred lease incentive:

Deferred Office Lease Expense

The office lease agreement, disclosed above, requires an initial annual base rent with annual increases over the next five years.  The Company recognizes rental expense on a straight-line basis over the term of the lease, which resulted in a deferred rent liability of $24,951 and $35,417 as of June 30, 2013 and December 31, 2012, respectively.

10.  Net Loss per Common Share
 
Basic loss per common share is computed by dividing net loss by the weighted average number of common shares outstanding for the period.  Diluted loss per common share is also computed by dividing net loss by the weighted average number of common shares outstanding, but also reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted from the issuance of common stock that would then share in earnings, and such calculation excludes common shares in treasury.   As of June 30 2013 and December 31, 2012, there were stock options and warrants to acquire 31,641,287 and 29,397,937 shares of our common stock, respectively, which are the potentially dilutive securities of the Company.

12. Stock-Based Compensation
 
At the Company’s Annual Meeting of the Stockholders held on June 10, 2013, the Company’s stockholders voted to approve the Rexahn Pharmaceuticals, Inc. 2013 Stock Option Plan (the “2013 Plan”).  Under the 2013 Plan, the Company grants stock options to key employees, directors and consultants of the Company.  A total of 17,000,000 shares of common stock have been reserved for issuance pursuant to the 2013 Plan.  As of June 30, 2013, there were 300,000 options outstanding, and 16,700,000 shares were available for issuance from the 2013 Plan.
 
On August 5, 2003, the Company established a stock option plan (the “2003 Plan”).  Under the 2003 Plan, the Company grants stock options to key employees, directors and consultants of the Company.  With the adoption of the 2013 Plan, no new stock options may be issued under the 2003 Plan, however, previously issued options under the 2003 Plan remain outstanding until their expiration.  As of June 30, 2013, there were 9,741,795 outstanding options under the 2003 Plan.
  
For the majority of the grants to employees, the vesting period is 30% on the first anniversary of the grant date, an additional 30% on the second anniversary of the grant date, and the remaining 40% on the third anniversary.  Options expire between five and ten years from the date of grant. For grants to non-employee consultants of the Company, the vesting period is between one and three years, subject to the fulfillment of certain conditions in the individual stock agreements, or 100% upon the occurrence of certain events specified in the individual stock agreements.

Summary of Stock Option Transactions
 
There were 1,200,000 stock options granted at an exercise price of $0.37 with a fair value of $320,465, 550,000 stock options granted at an exercise price of $0.31 with a fair value of $122,497, 250,000 stock options granted at an exercise price of $0.39 and a fair value of $69,529, and 300,000 stock options granted at an exercise price of $0.50 and a fair value of $107,086 during the six months ended June 30, 2013.  The 1,200,000 options granted at an exercise price of $0.37 were awarded to our new Chief Executive Officer, who joined the Company in February 2013.  Per that employment agreement, these options vested immediately, and therefore, the entire fair value of those options were expensed upon grant. There were 75,000 stock options granted at an exercise price of $0.48 and a fair value of $26,835 and 170,000 stock options granted at an exercise price of $0.38 and a fair value of $47,589 during the six months ended June 30, 2012.
  
The fair value of options at the date of grant was estimated using the Black-Scholes option pricing model.  The Company took into consideration guidance under ASC 718, “Compensation-Stock Compensation” and SAB 107 when reviewing and updating assumptions.  The expected volatility is based upon historical volatility of the Company’s stock.  The expected term is based upon the simplified method as allowed under SAB 107.

The assumptions made in calculating the fair values of options are as follows:

At June 30, 2013 and December 31, 2012, the average remaining contractual life of the outstanding warrants was 3.3 and 3.8 years, respectively.

The warrants, which were issued to investors in the December 2007, March 2008, May 2009, October 2009, June 2010, March 2011 and December 2012 offerings, contain a provision for net cash settlement in the event that there is a fundamental transaction (contractually defined as a merger, sale of substantially all assets, tender offer, or share exchange).   If a fundamental transaction occurs in which the consideration issued consists principally of cash or stock in a non-public company, then the warrant holder has the option to receive cash, equal to the fair value of the remaining unexercised portion of the warrant.  Due to this contingent redemption provision, the warrants require liability classification in accordance with ASC 480 and are recorded at fair value.  In addition, the warrants issued in the May 2009, October 2009, June 2010, March, 2011 and December 2012 offerings contain a cashless exercise provision that is exercisable only in the event that a registration statement is not effective, which provision may not be operative if an effective registration statement is not available because of an exemption under the U.S. Securities laws may not be available to issue unregistered shares.  As a result, net cash settlement may be required.
ASC 820 provides requirements for disclosure of liabilities that are measured at fair value on a recurring basis in periods subsequent to the initial recognition.  Fair values for warrants are determined using the Binomial Lattice (“Lattice”) valuation technique. The Lattice model provides for dynamic assumptions regarding volatility and risk-free interest rates within the total period to maturity. Accordingly, within the contractual term, the Company provided multiple date intervals over which multiple volatilities and risk free interest rates were used. These intervals allow the Lattice model to project outcomes along specific paths which consider volatilities and risk free rates that would be more likely in an early exercise scenario.

Significant assumptions are determined as follows:
Trading market values—published trading market values;
Exercise price—Stated exercise price;
Term—remaining contractual term of the warrant;
Volatility—Historical trading volatility for periods consistent with the remaining terms;
Risk-free rate—Yields on zero coupon government securities with remaining terms consistent with the remaining terms of the warrants.

Due to the fundamental transaction provision, which could provide for early redemption of the warrants, the model also considered the probability the Company would enter into a fundamental transaction during the remaining term of the warrant. Since the Company is still in its development stage and is not yet achieving positive cash flow, management believes the probability of a fundamental transaction occurring over the term of the warrant is unlikely and therefore estimates the probability of entering into a fundamental transaction to be 5%.  For valuation purposes, the Company also assumed that if such a transaction did occur, it was more likely to occur towards the end of the term of the warrants.

The warrants issued in December 2007 and March 2008 were not only subject to traditional anti-dilution protection, such as stock splits and dividends, but they were also subject to down-round anti-dilution protection. Accordingly, if the Company sold common stock or common stock indexed financial instruments below the stated exercise price, the exercise price related to these warrants will adjust to that lower amount.  The Lattice model used to value the warrants with down-round anti-dilution protection provides for multiple, probability-weighted scenarios at the stated exercise price and at five additional decrements/scenarios on each valuation date in order to encompass the value of the anti-dilution provisions in the estimate of fair value of the warrants. Calculations were performed at the stated exercise price and at five additional decrements/scenarios on each valuation date. The calculations provided for multiple, probability-weighted scenarios reflecting decrements that result from declines in the market prices. Decrements are predicated on the trading market prices in decreasing ranges below the contractual exercise price. For each valuation date, multiple Binomial Lattice calculations were performed which were probability weighted by considering both the Company’s (i) historical market pricing trends, and (ii) an outlook for whether or not the Company may need to issue equity or equity-indexed instruments in the future with a price less than the current exercise price.

The significant unobservable inputs used in the fair value measurement of the warrants include management’s estimate of the probability that a fundamental transaction may occur in the future.  Significant increases (decreases) in the probability of occurrence would result in a significantly higher (lower) fair value measurement.

14.  Put feature on Common Stock

The Anti-dilution provision extended in the December 2007 and March 2008 financings is a financial instrument separate and apart from the share. It is a freestanding written put (a put on the Company’s common stock).  As an enterprise value put, the contracts’ value moves inversely with the value of the underlying common stock which, under ASC 480, is not consistent with the general concepts or criterion for equity classified financial instruments. Accordingly, the written put was required to be classified as a liability under ASC 480 and recorded at fair value each reporting period, while the common stock achieved equity classification. Changes in the fair value of the anti-dilution make-whole provision are reported as “unrealized gain on fair value of put feature on common stock.”

The anti-dilution make-whole provisions associated with the common stock, were valued using a probability-weighting of put values provided by the Lattice model.  Additional value would result from the put upon an increase in the exercise price or upon decrease of the trading market price in the future. Since the exercise price is based on the actual sales price of the stock issued, it is not subject to adjustment unless there is an actual dilutive event. Therefore, the mechanism for determining the value of the put was to adjust the stock price input into the Lattice model based on the Company’s estimated future stock price.  A Random Walk Brownian Motion Stochastic Process (“Brownian”) technique was used to estimate the market price at several points in the future (e.g. at inception, 6 months, 12 months, 18 months and 24 months) over the term of the put to determine if the stock price will be expected to decrease over the related interval of time. Brownian is a continuous stochastic process that is widely used in financing for modeling random behavior that evolves over time, and a stochastic process is a sequence of events or paths generated by probabilistic laws. At each interval, the Brownian technique was run and the simulation returned the mean stock price (the “expected stock price”).
 
Expected stock prices returned from the stochastic model were then input into the Lattice model to provide a put value at each of the expected prices and these values were probability weighted to determine the overall fair value of the anti-dilution make-whole provision. The term was based on the remaining term of the put (two years at inception) and the inputs for volatility and interest rate were based on projected volatility and interest rate in the future over the remaining term.
 The following table summarizes the fair value of the Anti-dilution provision recorded at fair value as liabilities:

15.  Income Taxes
 
No provision for Federal and State income taxes was required for the three and six months ended June 30, 2013 and 2012 due to the Company’s operating losses and increased deferred tax asset valuation allowance.  At June 30, 2013 and December 31, 2012, the Company had unused net operating loss carry-forwards of approximately $65,090,000 and $61,780,000 which expire at various dates through 2033.  Some of this amount may be subject to annual limitations under certain provisions of the Internal Revenue Code related to “changes in ownership.”
 
As of June 30, 2013 and December 31, 2012, the deferred tax assets related to the aforementioned carry-forwards have been fully offset by valuation allowances, since significant utilization of such amounts is not presently expected in the foreseeable future.
 
Deferred tax assets and valuation allowances consist of:

The Company files income tax returns in the U.S. Federal and Maryland state jurisdictions.  Tax years for fiscal 2009 through 2013 are open and potentially subject to examination by the Federal and Maryland state taxing authorities.
16.      Commitments and Contingencies
 
a) The Company has contracted with various vendors to provide research and development services. The terms of these agreements usually require an initial fee and monthly or periodic payments over the term of the agreement, ranging from 2 months to 36 months. The costs to be incurred are estimated and are subject to revision. As of June 30, 2013, the total estimated cost to be incurred under these agreements was approximately $20,888,410 and the Company had made payments totaling $19,066,863 since inception under the terms of the agreements.  All of these agreements may be terminated by either party upon appropriate notice as stipulated in the respective agreements.
 
b) The Company and four of its key executives currently have outstanding employment agreements,.  The agreements result in annual commitments for each key executive of $350,000, $285,000, $250,000, and $215,000, respectively.
 
c) On June 22, 2009, the Company entered into a License Agreement with Korea Research Institute of Chemical Technology (“KRICT”) to acquire the rights to all intellectual properties related to Quinoxaline-Piperazine derivatives that were synthesized under a Joint Research Agreement.  The initial license fee was $100,000, all of which was paid as of December 31, 2009.  The agreement with KRICT calls for a one-time milestone payment of $1,000,000 within 30 days after the first achievement of marketing approval of the first commercial product arising out of or in connection with the use of KRICT’s intellectual properties.  As of June 30, 2013, the milestone has not occurred.
 
d) On June 29, 2009, the Company signed a five year commercial lease agreement for 5,466 square feet of office space in Rockville, Maryland commencing on June 29, 2009.  The lease agreement requires annual base rent with increases over the next five years.  Under the lease agreement, the Company pays its allocable portion of real estate taxes and common area operating charges. Rent paid under the Company’s lease during the three months ended June 30, 2013 and 2012 was $40,199 and $39,219, respectively. Rent paid under the Company’s lease during the six months ended June 30, 2013 and 2012 was $80,398 and $78,437.
 
On June 7, 2013 the Company entered into the First Amendment to the lease agreement. According to the terms of this amendment, the Company extended the lease term until June 30, 2019.  The amendment term began on July 1, 2013 with a base rent of $100,210 and requires annual base rent increases over the next six years.
