1.	Operations and Organization

Operations

Rexahn Pharmaceuticals, Inc. (the “Company”, or “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 $87,411,206 at March 31, 2014 and anticipates incurring losses through fiscal year 2014 and beyond. The Company has not yet generated commercial revenues and has funded its operating losses to date through the sale of shares of its common stock and warrants to purchase shares of its common stock, convertible debt, financings, interest income from cash and cash equivalents, and proceeds from reimbursed research and development costs. The Company believes that its cash, cash equivalents, and marketable securities, will be sufficient to cover its cash flow requirements for at least the next 24 months. 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 efficiently managing 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 March 31, 2014 and December 31, 2013 and of the results of operations and cash flows for the three months ended March 31, 2014 and 2013 have been included. Operating results for the three months ended March 31, 2014 are not necessarily indicative of results that may be expected for any other interim period or the full fiscal year ending December 31, 2014. 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, 2013 (“2013 Form 10-K”). Information included in the condensed balance sheet as of December 31, 2013 has been derived from the Company’s audited financial statements for the year ended December 31, 2013 included in the 2013 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 these estimates. These estimates are reviewed periodically, and as adjustments become necessary, they are reported in earnings in the period in which they become available.

6.	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 research and development expenses were reduced by $18,750 for the three months ended March 31, 2014 and 2013. The remaining $656,250 and $675,000 to be amortized at March 31, 2014 and December 31, 2013, respectively, are reflected as deferred research and development arrangements on the balance sheet. The payment from Rexgene 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 by Rexgene 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 2015. Under the terms of the agreement, Rexgene does not receive royalties on the Company’s net sales outside of Asia.

Teva Pharmaceutical Industries, Ltd.

On September 21, 2009, the Company closed on a securities purchase agreement (the “Purchase Agreement”) with Teva Pharmaceutical Industries Limited (“Teva”), and contemporaneous with the execution and delivery of this agreement, the parties executed a research and exclusive license option agreement (the “RELO Agreement”) pursuant to which the Company agreed to use proceeds from the issuance and sale of shares to Teva to fund a research and development program for the pre-clinical development of RX-3117. 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. Costs incurred for the development of RX-3117 are paid from restricted cash, reduce the deferred research and development arrangement and therefore are not an expense in the Company’s statement of operations. As of March 31, 2014 and December 31, 2013, the Company had proceeds remaining of $126,030 and $158,630, respectively, which are included in restricted cash and deferred research and development arrangements on the balance sheet. During the three months ended March 31, 2014 and 2013, $32,600 and $134,621, respectively, were reduced from the deferred research and development arrangement for costs incurred for the development of RX-3117 or for amounts returned to Teva as funds not allocated to specific projects. On August 28, 2013, the Company announced that Teva had decided not to exercise its option to license RX-3117, and as a result the RELO Agreement was terminated. The proceeds remaining from the restricted cash will be used to pay for unbilled expenses.

7.	Other Liabilities

Deferred Lease Incentive

On June 29, 2009, the Company entered into a five-year office lease agreement as disclosed in Note 13. 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 accounted for the benefit of the leasehold improvement allowance as a reduction of rental expense over the five-year term of the office lease.

On June 7, 2013, the Company entered into the first amendment to the lease agreement, also disclosed in Note 13. According to the terms of the amendment, the Company extended the lease term until June 30, 2019, and the amendment term began on July 1, 2013. The lessor agreed to grant an additional leasehold improvement allowance of $54,660 to the Company to be used for further construction to the leased property, furniture and equipment. The Company accounts for this benefit, including the unamortized portion from the original lease agreement, as a reduction of rental expense over the six-year amended term of the lease.

The following table sets forth the cumulative deferred lease incentive:

	March 31,			December 31,
	2014			2013

Deferred lease incentive	$	154,660		$	154,660
Less accumulated amortization		(89,333	)		(86,222	)

Balance	$	65,327		$	68,438

Deferred Office Lease Expense

The lease agreement, as amended and disclosed above, requires an initial annual base rent with annual increases over the next six 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 $72,951 and $61,126 as of March 31, 2014 and December 31 2013, respectively.

8.	Net Loss per Common Share

Basic loss per common share is computed by dividing net loss by the weighted average number of shares of common stock outstanding for the period. Diluted loss per common share is computed by dividing net loss by the weighted average number of shares of common stock outstanding, plus the number of common share equivalents that would be dilutive. As of March 31, 2014 and December 31, 2013, there were stock options and warrants to acquire, in the aggregate, 29,167,196 and 34,325,663 shares of our common stock, respectively, that are potentially dilutive. However, diluted loss per share for the three months ended March 31, 2014 and 2013 is the same as basic loss per share because the inclusion of common share equivalents would be anti-dilutive.

9.	Common Stock

The following transactions occurred from January 1, 2014 to March 31, 2014:

On January 21, 2014 the Company closed on a registered direct public offering to issue and sell 19,047,620 shares of common stock and warrants to purchase up to 4,761,905 shares of common stock. The common stock and warrants were sold in units, consisting of common stock and a warrant to purchase 0.25 shares of common stock, at a price of $1.05 per share, and the warrants have an exercise price of $1.28 per share. The total gross proceeds of the offering were $20,000,001. The warrants issued are exercisable beginning six months and one day after the closing date until the five-year anniversary of the closing date and were recorded as liabilities at fair value.

The total closing costs of the offering were $1,365,754, which consisted of placement agent and other professional fees. Based upon the estimated fair value of the stock and warrants in the units, the Company allocated $206,172 to financing expense and $1,159,582 as stock issuance costs.

A summary of the allocation of the proceeds of the offering is shown below:

Gross Proceeds:	$	20,000,001

Warrant liabilities		3,691,429

10.	Stock-Based Compensation

As of March 31, 2014, the Company had 10,245,294 options outstanding.

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 March 31, 2014, there were 1,425,999 options outstanding under the 2013 Plan, and 15,574,001 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 granted 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, but previously issued options under the 2003 Plan remain outstanding until their expiration. As of March 31, 2014, there were 8,819,295 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.

Accounting for Employee Awards

The Company’s results of operations for the three months ended March 31, 2014 and 2013 include share-based employee compensation expense totaling $109,442 and $366,111, respectively. Such amounts have been included in the statement of operations in general and administrative and research and development expenses. No income tax benefit has been recognized in the statement of operations for share-based compensation arrangements as the Company has provided for a 100% valuation allowance on its deferred tax assets.

Employee stock option compensation expense is the estimated fair value of options granted amortized on a straight-line basis over the requisite vesting service period for the entire portion of the award.

Accounting for Non-Employee Awards

Stock compensation expenses related to non-employee options were $18,908 and $5,840 for the three months ended March 31, 2014 and 2013, respectively. Such amounts have been included in the statement of operations in general and administrative and research and development expenses.

The warrants issued to investors in the 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. The warrants issued to investors in the July 2013, October 2013 and January 2014 offerings contain a fundamental transaction provision, but the warrant holders only have an option as to the type of consideration received if the holders of common stock receive an option as to their consideration. In addition, the warrants issued in the May 2009, October 2009, June 2010, March 2011, December 2012, July 2013, October 2013, and January 2014 offerings contain a cashless exercise provision that is exercisable only in the event that a registration statement is not effective. That provision may not be operative if an effective registration statement is not available because 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, and the warrants require liability classification.

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 that 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. Because 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 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.

12.	Income Taxes

No provision for federal and state income taxes was required for the three months ended March 31, 2014 and 2013 due to the Company’s operating losses and increased deferred tax asset valuation allowance. At March 31, 2014 and December 31, 2013, the Company had unused net operating loss carry-forwards of approximately $71,700,000 and $69,036,000, which expire at various dates through 2034. 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 March 31, 2014 and December 31, 2013, 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:

	March 31,			December 31,
	2014			2013

Net Operating Loss Carryforwards	$	27,963,000			26,924,000
Stock Compensation Expense		2,059,500			2,028,200
Book tax differences on assets and liabilities		321,000			424,000

The Company files income tax returns in the U.S. federal and Maryland state jurisdictions. Tax years for fiscal 2010 through 2014 are open and potentially subject to examination by the federal and Maryland state taxing authorities.

As of March 31, 2014, the total estimated cost to be incurred under these agreements was approximately $26,212,772, and the Company had made payments totaling $20,934,687 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.

The Company and four of its key executives currently have outstanding employment agreements. The agreements result in annual commitments for each key executive of $330,000, $285,000, $250,000 and $250,000, respectively.

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 March 31, 2014, the milestone has not occurred.

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 required 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 March 31, 2014 and 2013, including the amendment terms described below, was $25,053 and $40,199, respectively.

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 remaining term of the lease.

Future rental payments over the next five years are as follows:

For the remaining nine months ending December 31:	2014		114,622
For the year ending December 31:	2015		156,000
	2016		159,881
	2017		163,871
	2018		167,970
	2019		85,024

	Total	$	847,368

In connection with the lease agreement, the Company issued a letter of credit of $100,000 in favor of the lessor. On August 2, 2010, and July 1, 2011 the letter of credit was amended and reduced to $50,000 and $37,500, respectively. The Company has restricted cash equivalents of the same amount for the letter of credit.

On September 21, 2009, the Company closed on the Purchase Agreement with Teva, and contemporaneous with the execution and delivery of this agreement, the parties executed the RELO Agreement, pursuant to which the Company agreed to use proceeds from the issuance and sale of shares to Teva to fund a research and development program for the pre-clinical development of RX-3117. On December 27, 2012, the Company received $926,000 from Teva in accordance with a second amendment to the RELO Agreement, entered into on November 27, 2012. The Company did not issue equity for this transaction. On August 28, 2013, the Company announced that Teva had decided not to exercise its option to license RX-3117, and as a result the RELO Agreement was terminated. The remaining proceeds of $126,030, which is included in restricted cash equivalents at March 31, 2014 will be used to pay for unbilled expenses.

The Company has established a 401(k) plan for its employees. The Company has elected to match 100% of the first 3% of an employee’s compensation plus 50% of an additional 2% of the employee’s deferral. Expense related to this matching contribution aggregated to $20,700 and $17,716 for the three months ended March 31, 2014 and 2013, respectively.

On June 24, 2013 and May 30, 2012, the Company signed a one-year renewal to use laboratory space commencing on July 1, 2013 and 2012, respectively. The lease requires monthly rental payments of $4,554. Rent paid under the Company’s lease during the three months ended March 31, 2014 and 2013 was $13,662.

In July 2013, the Company entered into an exclusive license agreement with the University of Maryland, Baltimore for a novel drug delivery platform, Nano-Polymer Drug Conjugate Systems. RX-21101 is the Company’s first drug candidate utilizing this platform. The agreement requires the Company to make payments to the University of Maryland if RX-21101 or any products from the licensed delivery platform achieve development milestones. As of March 31, 2014, no development milestones have occurred.

In October 2013, the Company signed an exclusive license agreement with the Ohio State Innovation Foundation, for a novel oligonucleotide drug delivery platform, Lipid-Coated Albumin Nanoparticle (“LCAN”). The agreement requires the Company to make payments to the Ohio State Innovation Foundation or any products from the licensed delivery platform achieve development milestones. As of March 31, 2014, no development milestones have occurred.

14.	Fair Value Measurements

ASC 820 defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date, not adjusted for transaction costs. ASC 820 also establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three broad levels giving the highest priority to quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3).

The three levels are described below:

Level 1 Inputs	—	Unadjusted quoted prices in active markets for identical assets or liabilities that are accessible by the Company;

Level 2 Inputs	—	Quoted prices in markets that are not active or financial instruments for which all significant inputs are observable, either directly or indirectly;

Level 3 Inputs	—	Unobservable inputs for the asset or liability including significant assumptions of the Company and other market participants.

The following tables present assets and liabilities that are measured at fair value on a recurring basis and are categorized using the fair value hierarchy.

	Fair Value Measurements at March 31, 2014
	Total		Level 1		Level 2		Level 3
Assets:

As of March 31, 2014 and December 31, 2013, the Company’s restricted cash equivalents are comprised of the following:

Money market funds valued at the net asset value of shares held by the Company and classified within level 1 of the fair value hierarchy;

Certificate of deposit valued based upon the underlying terms of a letter of credit, as disclosed in Note 13 and classified within level 2 of the fair value hierarchy.

Marketable securities consist of state authority and municipal security fund bonds that are valued at fair value and classified within level 1 of the fair value hierarchy.

The fair value methodology for the warrant liabilities is disclosed in Note 11.

The carrying amounts reported in the financial statements for cash and cash equivalents (Level 1), prepaid expenses, and other current assets and accounts payable and accrued expenses approximate fair value because of the short term maturity of these financial instruments.

The following table sets forth a reconciliation of changes in the three months ended March 31, 2014 and 2013 in the fair value of the liabilities classified as level 3 in the fair value hierarchy:

	Warrant Liabilities
Balance at January 1, 2014	$	5,034,058
Additions		3,691,429
Unrealized losses, net		11,660,524
Unrealized gains on expiration		-
Transfers out of level 3		(9,095,445	)
Balance at March 31, 2014	$	11,290,566

	Warrant Liabilities
Balance at January 1, 2013	$	2,842,065
Additions		-
Unrealized gains, net		(368,902	)
Unrealized gains on expiration		-
Transfers out of level 3		-
Balance at March 31, 2013	$	2,473,163

Additions consist of the fair value of warrant liabilities upon issuance. Transfers out of Level 3 for warrant liabilities consist of warrant exercises, where the liability is converted to additional paid-in capital upon exercise. The Company’s policy is to recognize transfers in and transfers out as of the actual date of the event or change in circumstance that caused the transfer. There were no significant transfers in and out of Levels 1 and 2 for the three months ended March 31, 2014 and 2013.

Table of Contents

We are a clinical development stage biopharmaceutical company dedicated to the discovery, development and commercialization of innovative treatments for cancer patients that target specific proteins that are over expressed in cancer cells and not present in normal healthy tissues resulting in increased efficacy and reduced side effects. This approach differs from existing chemotherapeutic agents that inhibit the growth of both cancer cells and normal healthy tissues at similar doses. Our pipeline features one oncology candidate in Phase II clinical trials, two oncology candidates in Phase I clinical trials, two drug candidates not currently being actively developed and several other drug candidates in pre-clinical development. Our strategy is to continue building a significant product pipeline of innovative drug candidates that we will commercialize alone or with partners. We intend to initially develop drug candidates for cancers that are orphan indications and then expand into more highly prevalent cancers.

Since our inception, our efforts and resources have been focused primarily on developing our pharmaceutical technologies, raising capital and recruiting personnel. As a development stage company, we have no product sales to date, and we will not generate any product sales until we receive approval from the Food and Drug Administration (the “FDA”) or equivalent foreign regulatory bodies to begin selling our pharmaceutical candidates. Our major sources of working capital have been proceeds from various private financings, primarily private sales of common stock and debt securities and collaboration agreements with our strategic investors.

Results of Operations

Comparison of the Three Months Ended March 31, 2014 and March 31, 2013

Total Revenues

We had no revenues for the three months ended March 31, 2014 or 2013.

General and Administrative Expenses

General and administrative expenses consist primarily of salaries and related expenses for executive, finance and other administrative personnel, recruitment expenses, professional fees and other corporate expenses, including business development, investor relations, and general legal activities.

General and administrative expenses increased $202,704, or 16.7%, to $1,413,456 for the three months ended March 31, 2014 from $1,210,752 for the three months ended March 31, 2013. The increase is primarily attributable to increases in several expense categories, including investor relations and financial advisory services. During the three months ended March 31, 2014, we engaged multiple firms to provide investor relations and financial advisory services surrounding financing transactions, compared to one firm during the three months ended March 31, 2013, and some of these firms were compensated with compensatory stock in addition to cash payments. The increase in general and administrative expenses is also partially attributable to an increase in legal fees relating to corporate organizational matters. The overall increase in general and administrative expenses for the three months ended March 31, 2014 compared to the three months ended March 31, 2013 is offset by a decrease in stock based compensation and recruiting fees.

Research and Development Expenses

Research and development expenses consist primarily of salaries and related personnel costs, fees paid to consultants and outside service providers for laboratory development and other expenses relating to the design, development, testing, and enhancement of our drug candidates. We expense our research and development costs as they are incurred.

Research and development expenses increased $719,108, or 130.16%, to $1,271,574 for the three months ended March 31, 2014, from $552,466 for the three months ended March 31, 2013. The increase is primarily attributable to the clinical trials that were on-going during the three months ended March 31, 2014. During the three months ended March 31, 2014, one of our drug candidates, Archexin, entered a Phase IIa clinical trial to study its safety and efficacy in patients with metastatic renal cell carcinoma (“RCC”), and another drug candidate, RX-3117, entered a Phase Ib clinical trial to study its safety and efficacy in patients with solid tumors. During the three months ended March 31, 2014, we incurred expenses of approximately $450,000 and $275,000 related to the Archexin and RX-3117 clinical trials, respectively.

Table of Contents

Patent Fees

Our patent fees decreased $64,471, or 47.2%, to $72,020 for the three months ended March 31, 2014, from $136,491 for the three months ended March 31, 2013. The decrease is primarily attributable to a partial reduction of our patent fees related to our central nervous system patents, as well as translation fees associated with regionalizing patents in foreign jurisdictions during the three months ended March 31, 2013.

Depreciation and Amortization

Depreciation and amortization expense essentially remained flat for the three months ended March 31, 2014 compared to the three months ended March 31, 2013, decreasing $272, or 2.9%.

Interest Income

Interest income increased $22,273 or 222.3% to $32,291 for the three months ended March 31, 2014 from $10,018 for the three months ended March 31, 2013. The increase is due to an increase in interest rates and higher cash balances on our cash and cash equivalents for the three months ended March 31, 2014 compared to the three months ended March 31, 2013.

Unrealized (Loss)/Gain on Fair Value of Warrants

Our warrants are recorded as liabilities at fair value, and the warrants are valued using a lattice model. Changes in the fair value of warrants are recorded as an unrealized gain or loss in our statement of operations. During the three months ended March 31, 2014 and 2013, we recorded an unrealized (loss) gain on the fair value of our warrants of $(11,660,524) and $368,902, respectively. Estimating fair values of warrants requires the development of significant and subjective estimates that may, and are likely to, change over the duration of the warrant with related changes to external and internal market factors. The large unrealized loss for the three months ended March 31, 2014 primarily resulted from an increased stock price of the underlying common stock at March 31, 2014.

Financing Expense

We incurred $206,172 of financing expenses during the three months ended March 31, 2014, related to our registered direct offering in January 2014. We did not incur financing expenses during the three months ended March 31, 2013.

Net Loss

As a result of the above, net loss for the three months ended March, 31 2014 was $14,600,499, or $0.09 per share, compared to $1,530,105, or $0.01 per share, for the three months ended March 31, 2013.

Research and Development Projects

Research and development costs are expensed as incurred. Research and development costs consist primarily of salaries and related personnel costs, costs to acquire pharmaceutical products and product rights for development and amounts paid to contract research organizations, hospitals and laboratories for the provision of services and materials for drug development and clinical trials. Costs incurred in obtaining the license rights to technology in the research and development stage that have no alternative future uses are expensed as incurred. Our research and development programs are related to our oncology clinical stage drug candidates, Archexin, RX-3117 and Supinoxin, and our pre-clinical stage drug candidates, RX-0047-Nano, Archexin-Nano and RX-21101. Each of our drug candidates is in a different stage of completion as described below. As we expand our clinical studies, we will enter into additional development agreements. Significant additional expenditures will be required if we complete our clinical trials, start new trials, apply for regulatory approvals, continue development of our technologies, expand our operations and bring our products to market. The eventual total cost of each clinical trial is dependent on a number of uncertainties such as trial design, the length of the trial, the number of clinical sites and the number of patients. The process of obtaining and maintaining regulatory approvals for new therapeutic products is lengthy, expensive and uncertain. Because the successful development of our most advanced drug candidates, Archexin, RX-3117 and Supinoxin, is uncertain, and because RX-0047-Nano, Archexin-Nano, and RX-21101 are in early-stage development, we are unable to estimate the costs of completing our research and development programs, the timing of bringing such programs to market and, therefore, when material cash inflows could commence from the sale of these drug candidates, if any. If these projects are not completed as planned, our results of operations and financial condition would be negatively affected.

Archexin^®

Archexin is a potential best-in-class, potent inhibitor of the protein kinase phosphorylated Akt-1, which is over expressed in cancer cells and which we believe plays a critical role in cancer cell proliferation, survival, angiogenesis, metastasis and drug resistance. Archexin has received “orphan drug” designation from the FDA, for renal cell carcinoma, (“RCC”), glioblastoma, ovarian cancer, stomach cancer and pancreatic cancer. That designation provides tax incentives for clinical research and a waiver of user fees. In addition, a drug that is approved for its orphan-designated use receives seven years of exclusivity after approval, during which the FDA generally cannot approve another product with the same active moiety for the same indication.

In August 2012, we announced top line results of an open label 2-stage Phase IIa clinical trial for Archexin that was designed to assess the safety and efficacy of Archexin in combination with gemcitabine. Gemcitabine is used to treat pancreatic, breast, ovarian and lung cancers. Gemcitabine is a member of a group of chemotherapy drugs known as anti-metabolites. It prevents cells from making DNA and RNA, which stops cell growth and causes cells to die. Stage 1 was the dose-finding portion of the study, and Stage 2 was the dose-expansion portion of the study using the dose identified in Stage 1 administered with gemcitabine. The study enrolled 31 subjects aged 18 to 65 with metastatic pancreatic cancer at nine centers in the United States and India. The primary endpoint was overall survival following four cycles of therapy with a six month follow-up. For those evaluable patients, the study demonstrated that treatment with Archexin in combination with gemcitabine provided a median survival rate of 9.1 months compared to the historical survival data of 5.65 months for standard single agent gemcitabine therapy. The most frequent reported adverse events were constipation, nausea, abdominal pain and pyrexia, regardless of relatedness.

We initiated a Phase IIa clinical proof-of-concept clinical trial of Archexin in January 2014 to study its safety and efficacy in patients with metastatic RCC. In the trial, Archexin will be administered in combination with everolimus (Afinitor®), and will be conducted in two stages. The first stage will be dose ranging, with up to three cohorts of three RCC patients to determine its maximal tolerated dose (“MTD”) in combination with everolimus. Once the MTD has been determined, thirty RCC patients will be randomized to either Archexin in combination with everolimus or everolimus alone, in a ratio of 2:1. Rexahn plans to complete the initial safety component of this study in the fourth quarter of 2014. We estimate the costs of that study to be approximately $5,000,000. We own one issued U.S. patent for Archexin.

Table of Contents

As of March, 31, 2014, we have spent approximately $7,229,000 for the development of Archexin. The Phase IIa trial for pancreatic cancer was completed in the third quarter of 2012, and we estimate that we have approximately an additional $95,000 of costs yet to be billed by vendors for this trial.

RX-3117

RX-3117 is a small molecule nucleoside compound with an anti-metabolite mechanism of action, and we believe it has therapeutic potential in a broad range of cancers including colon, lung, and pancreatic cancer. RX-3117 has also been shown to be effective in inhibiting the growth of gemcitabine-resistant human cancers and in improving overall survival in pre-clinical animal models. We completed an exploratory Phase I clinical study of RX-3117 in 2012 that demonstrated the oral bioavailability of RX-3117 in humans with no adverse effects reported in the study. In January 2014, we initiated a Phase Ib clinical trial to study the safety, tolerability, dose-limiting toxicities and MTD of RX-3117 in patients with solid tumors. Secondary endpoints will include characterizing the pharmacokinetic profile of RX-3117 and evaluating the preliminary anti-tumor effects of RX-3117. Rexahn has completed one dose cycle (30mg) and is in the middle of the second dose cycle (100mg). We estimate the costs of that Phase Ib clinical study to be approximately $5,100,000. As of March 31, 2014, we have spent approximately $4,940,000 for the development of RX-3117.

Supinoxin (RX-5902)

Supinoxin is a potential first-in-class small molecule that inhibits the phosphorylation of p68 RNA helicase, a protein that we believe plays a key role in cancer growth, progression and metastasis. Phosphorylated p68, which is highly expressed in cancer cells, but not in normal cells, results in up-regulation of cancer-related genes and a subsequent proliferation or tumor growth of cancer cells. Supinoxin selectively blocks phosphorylated p68, thereby decreasing the proliferation or growth of cancer cells. In pre-clinical tissue culture models and in-vivo xenograft models, Supinoxin has demonstrated synergism with cytotoxic agents and activity against drug resistant cancer cells. In particular, in in-vivo xenograft models of human renal cell carcinoma and pancreatic cancer, treatment with Supinoxin on days 1 to 20 in mouse models produced a survival benefit beyond 65 days. In July 2012, we submitted an investigational new drug (“IND”) application to the FDA for Supinoxin. We initiated a Phase I clinical trial in August 2013 to study Supinoxin’s safety and efficacy in patients with solid tumors. The MTD of Supinoxin has not yet been achieved. Three dosing cycles (25mg, 50mg, 100mg) and no drug related adverse events have been reported. The fourth dosing cycle is ongoing. We estimate the costs of that study to be approximately $2,700,000.

As of March 31, 2014, we have incurred approximately $2,059,000 for the development of Supinoxin.

Pre-clinical Pipeline

Archexin-Nano, RX-0047-Nano and RX-21101 are all in a pre-clinical stage of development. Through March 31, 2014, the costs incurred for development of these compounds to date have been approximately $2,650,000. The estimated cost to complete pre-clinical toxicology and Phase I clinical trials is estimated to be approximately $1,500,000 for each compound.

Research and Development Process

We have engaged third-party contract research organizations and other investigators and collaborators, such as universities and medical institutions, to conduct our pre-clinical studies, toxicology studies and clinical trials. For example, for the development of Archexin, we have engaged multiple third-parties, including the Lombardi Comprehensive Cancer Center of Georgetown Medical Center and the University of Alabama at Birmingham, where Phase I clinical trials were conducted, and Amarex, LLC, a pharmaceutical clinical research service provider.

Engaging third-party contract research organizations is typical practice in our industry. However, relying on such organizations means that the clinical trials and other studies described above are being conducted at external locations and that the completion of these trials and studies is not within our direct control. Trials and studies may be delayed due to circumstances outside our control, and such delays may result in additional expenses for us.

Collaboration and License Agreements

In July 2013, we entered into an exclusive license agreement with the University of Maryland, Baltimore for a novel drug delivery platform, Nano-Polymer-Drug Conjugate Systems. This platform combines existing chemotherapeutic agents with a proprietary polymer carrier that contains a signaling moiety to direct the agents into a tumor. RX-21101 is our first drug candidate utilizing this platform and is a conjugated form of docetaxel, a common chemotherapy agent.

In October 2013, we entered into an exclusive license agreement with the Ohio State Innovation Foundation, an affiliate of the Ohio State University, for a novel oligonucleotide drug delivery platform, Lipid-Coated Albumin Nanoparticle (“LCAN”). The LCAN platform incorporates both cationic lipid and cationized albumin that can form an electrostatic complex with oligonucleotides and be co-encapsulated by lipids. Archexin-Nano is our first drug candidate to be developed with this platform.

Liquidity and Capital Resources

Operating Activities

Cash used in operating activities was $2,576,607 for the three months ended March 31, 2014. The operating cash flows during the three months ended March 31, 2014 reflect our net loss of $14,600,499, which includes an unrealized loss on fair value of warrants of $11,660,524 and a net increase of cash components of working capital and other non-cash charges totaling $363,368. Cash used in operating activities was $1,551,527 for the three months ended March 31, 2014.

Cash provided by investing activities was $28,829 for the three months ended March 31, 2014, which consisted of a decrease in restricted cash of $32,600 offset by $3,771 for the purchase of equipment. Cash provided by investing activities for the three months ended March 31, 2013 was $134,012.

Cash provided by financing activities was $23,932,765 for the three months ended March 31, 2014, which consisted of net proceeds of $18,634,247 from our registered direct public offering in January 2014, $70,000 from the exercise of stock options and $5,228,518 from the exercise of stock warrants. There was no cash provided by financing activities for the three months ended March 31, 2013.

We will need to raise additional capital through public or private equity or debt offerings or through arrangements with strategic partners or other sources in order to continue to develop our drug candidates. There can be no assurance that additional capital will be available when needed or on terms satisfactory to us, if at all. If we are not able to raise sufficient additional capital, we will have to reduce our research and development activities. We will first reduce research and development activities associated with our pre-clinical compounds. To the extent necessary, we will then reduce our research and development activities related to some or all of our clinical drugs.

Contractual Obligations

We have contracted with various vendors for research and development services. The terms of these agreements usually require an initiation fee and monthly or periodic payments over the term of the agreement, ranging from two months to 36 months. The costs to be incurred are estimated and are subject to revision. As of March 31, 2014, the total contract value of these agreements was approximately $26,212,772 and we had made payments totaling $20,934,687 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.

On September 9, 2010, we and three of our key executives entered into Amended and Restated Employment Agreements. The Amended and Restated Employment Agreements replace the prior employment contracts entered into on August 10, 2009. We entered into the Amended and Restated Employment Agreements in order to provide each of the key executives with: (i) an automatic one-year renewal upon the expiration of the initial three-year term and upon each consecutive year term unless such employment with us is terminated earlier by us or the executive; (ii) an annual base salary adjustment for inflation as determined by the Consumer Price Index subject to review by our Compensation Committee; (iii) an increase in the life insurance coverage from an amount equal to two times the executive’s annual base salary to an amount equal to four times the executive’s annual base salary; and (iv) a one-time cash payment, subject to applicable withholding requirements under applicable state and federal law, in an amount equal to the executive’s increased income tax costs as a result of payments made to the executive by us under the change of control provisions of the Amended and Restated Employment Agreement. Other than these changes, the new contracts have substantially similar terms to the executives’ prior employment agreements. The agreements resulted in annual commitments of $350,000 to Dr. Chang H. Ahn, our former Chief Executive Officer and current Chief Scientist, $250,000, to Mr. Rakesh (Rick) Soni, our President and Chief Operating Officer, and $250,000 to Dr. Tae Heum Jeong, our Chief Financial Officer.

Effective as of February 4, 2013, we entered into an employment agreement with Dr. Peter Suzdak to serve as our Chief Executive Officer for a term of two years with the option to renew the employment agreement for additional one-year periods thereafter until terminated. Pursuant to that employment agreement, we agreed to pay Dr. Suzdak an annual base salary of $330,000, with the option of a discretionary annual cash bonus of up to 40% of his base salary, as determined by performance objectives and milestones set by the Board of Directors.

On March 25, 2013, we entered into a new employment agreement with Dr. Ahn to serve as our Chief Scientist. This employment agreement replaces and supersedes Dr. Ahn’s prior Amended and Restated Employment Agreement, dated as of September 9, 2010. The employment agreement has a one-year term with an automatic renewal option for additional one-year periods thereafter until terminated. Pursuant to the employment agreement, we agreed to pay Dr. Ahn an annual base salary of $285,000 with the option of a discretionary annual cash bonus as determined by our Compensation Committee based on performance objectives and milestones set by the Board of Directors. The employment agreement also provides for a discretionary stock option award to purchase shares of our common stock on each anniversary of the employment agreement as determined by the Board of Directors. Any such stock option awards are to be granted in accordance with the terms of the 2013 Plan.

On June 22, 2009, we 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 March 31, 2014, this milestone has not occurred.

On June 29, 2009, we signed a five year lease for 5,466 square feet of office space in Rockville, Maryland commencing on June 29, 2009. Under the lease agreement, we pay our allocable portion of real estate taxes and common area operating charges in addition to annual base rent. We paid $25,053 and $40,199, for rent under this lease, including the amended terms described below, during the three months ended March 31, 2014 and 2013, respectively. On June 7, 2013, we entered into the first amendment to the lease agreement. According to the terms of the amendment, we extended our lease term until June 30, 2019. The amendment term begins on July 1, 2013 with an annual base rent of $100,210 and requires annual base rent increases over the remaining term of the lease.

In connection with the lease agreement, we issued a letter of credit of $100,000 in favor of the lessor. On August 2, 2010 and July 1, 2011, the letter of credit was reduced to $50,000 and $37,500 respectively. We have restricted cash equivalents of the same amount for the letter of credit.

On September 21, 2009, we closed on a securities purchase agreement with Teva Pharmaceutical Industries Limited (“Teva”), and contemporaneous with the execution and delivery of this agreement, the parties executed a research and exclusive license option agreement (the “RELO Agreement”), pursuant to which we agreed to use proceeds from the issuance and sale of shares to Teva to fund a research and development program for the pre-clinical development of RX-3117. On December 27, 2012, we received $926,000 of research funding for the development of RX-3117 from Teva in accordance with a second amendment to the RELO Agreement, entered into on November 27, 2012. We did not issue equity for this transaction. On August 28, 2013, we announced that Teva had decided not to exercise its option to license RX-3117, and as a result, the RELO Agreement was terminated. The remaining proceeds of $126,030, which is included in restricted cash equivalents at March 31, 2014, will be used to pay for unbilled expenses.

On June 24, 2013 and May 30, 2012, we signed a one-year renewal to use lab space commencing on July 1, 2013 and 2012, respectively. The lease requires monthly rental payments of $4,554. Rent paid under the lease during the three months ended March 31, 2014 and 2013 was $13,662.

We have established a 401(k) plan for our employees under which we match 100% of the first 3% of an employee’s deferral plus 50% of an additional 2% of the employee’s deferral. Expense related to this matching contribution aggregated to $20,700 and $17,716 for the three months ended March 31, 2014 and 2013, respectively.

In July 2013, we entered into an exclusive license agreement with the University of Maryland, Baltimore for a novel drug delivery platform, Nano-Polymer Drug Conjugate Systems. The agreement requires us to make payments to the University of Maryland if RX-21101 or any products from the licensed delivery platform achieve development milestones. As of March 31, 2014, no development milestones have occurred

In October 2013, we entered into an exclusive license agreement with the Ohio State Innovation Foundation, for a novel oligonucleotide drug delivery platform. The agreement requires us to make payments to the Ohio State Innovation Foundation or any products from the licensed delivery platform achieve development milestones. As of March 31, 2014, no development milestones have occurred.

Current and Future Financing Needs

We have incurred negative cash flow from operations since we started our business. We have spent, and expect to continue to spend, substantial amounts in connection with implementing our business strategy, including our planned product development efforts, our clinical trials and our research and development efforts. Total cash, including restricted cash, and marketable securities, was $40,336,548 as of March 31, 2014. Based on our current plans and our capital resources, we believe that our cash, restricted cash and marketable securities will be sufficient to enable us to meet our minimum planned operating needs over the next 24 months, which would entail focusing our resources on Phase IIa clinical trials of Archexin, Phase I clinical trials of RX-3117 and Supinoxin and the further development of our pre-clinical pipeline. Over the next 12 months, we expect to spend a minimum of approximately $2.1 million for Phase IIa clinical trials of Archexin. We also expect to pay $2.9 million for the Phase Ib clinical trials of RX-3117, $1.4 million on the development of Supinoxin, $3.3 million for the development of our pre-clinical pipeline and general research and development costs, and $3.8 million on general corporate expenses. These figures include our commitments described earlier under “Contractual Obligations” under this Item 2. We will need to raise additional capital through public or private equity or debt offerings or through arrangements with strategic partners or other sources in order to continue to develop our drug candidates. There can be no assurance that additional capital will be available when needed or on terms satisfactory to us, if at all. If we are not able to raise sufficient additional capital, we will have to reduce our research and development activities.

However, the actual amount of funds we will need to operate is subject to many factors, some of which are beyond our control. These factors include the following:

the progress of our product development activities;

the number and scope of our product development programs;

the progress of our pre-clinical and clinical trial activities;

the progress of the development efforts of parties with whom we have entered into collaboration agreements;

our ability to maintain current collaboration programs and to establish new collaboration arrangements;

Item 4.

Controls and Procedures.

Disclosure Controls and Procedures

As of the end of the period covered by this Quarterly Report on Form 10-Q, we carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer (“CEO”) along with our Chief Financial Officer (“CFO”), of the effectiveness of our disclosure controls and procedures (as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)). Based on that evaluation, the CEO along with the CFO concluded that our disclosure controls and procedures were effective as of the end of the period covered by this report.

Our management, including the CEO and CFO, does not expect that our disclosure controls and internal controls will prevent all errors and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, have been detected. These inherent limitations include the realities that judgments in decision making can be faulty and that breakdowns can occur because of simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people or by management override of the controls.

Changes in Internal Control Over Financial Reporting

There have not been any changes in our internal controls over financial reporting (as such term is defined in Rule 13a-15(f) under the Exchange Act) during the quarter ended March 31, 2014 that have materially affected, or are reasonably likely to materially affect, our internal controls over financial reporting.

Risk Factors.

Please refer to our Annual Report on Form 10-K for the year ended December 31, 2013 (the “2013 Form 10-K”) for disclosures with respect to our risk factors, which could materially affect our business, financial condition, or future results. The risks described in the 2013 Form 10-K are not the only risks we face. Additional risks and uncertainties not currently known to us or that we currently deem immaterial may also adversely affect our business, financial condition or future results.

Item 2.

Unregistered Sales of Equity Securities and Use of Proceeds.

Pursuant to a consulting agreement, we issued 100,000 shares of common stock on February 10, 2014, to a privately held investor relations firm in consideration for investor relations services. The shares of common stock were not registered under the Securities Act of 1933, as amended (the “Securities Act”) pursuant to the exemptions from registration requirements provided by Section 4(a)(2) of the Securities Act, as a transaction not involving a public offering.

Pursuant to an advisory service agreement, we issued 200,000 shares of common stock on February 10, 2014, to a privately held financial advisory firm in consideration for financial advisory services. The shares of common stock were not registered under the Securities Act pursuant to the exemption from registration requirements provided by Section 4(a)(2) of the Securities Act, as a transaction not involving a public offering.

During the three months ended March 31, 2014, the Company issued 519,349 shares of common stock to warrant holders upon exercise of unregistered warrants that were issued pursuant to an underwriting agreement, dated November 29, 2012 between the Company, Maxim Group LLC and Burrill LLC. The warrants were not registered under the Securities Act of 1933, as amended pursuant to the exemption from registration requirements provided by Section 4(a)(2) of the Securities Act, as a transaction not involving a public offering.
