1. Company Description and Summary of Significant Accounting Policies

Nature of Business

Ocuphire Pharma, Inc. (Ocuphire or the Company) was incorporated as a C-corporation in the state of Delaware on February 21, 2018.  On April 9, 2018, Ocularis Pharma, LLC, a Delaware limited liability company (LLC), and Ocularis Pharma, Inc., an Illinois Subchapter S-corporation (the S-Corp), entered into merger agreements with Ocuphire whereby the LLC and the S-Corp were merged with and into Ocuphire effective April 10, 2018 (the LLC Merger), with Ocuphire as the surviving entity. All outstanding membership interests of the LLC and all outstanding shares of capital stock of the S-Corp were exchanged for shares of Ocuphire common stock. One of the purposes of the LLC Merger was to convert the LLC to a C-corporation.  All financial results presented prior to April 10, 2018 are from the operations of the LLC. The S-Corp did not have an integrated set of activities that contained the required complement of inputs, processes and outputs to be considered a business. As such, the S-Corp with regard to the LLC Merger was accounted for as an asset acquisition as prescribed under Accounting Standards Codification (ASC) 805 – Business Combinations. The S-Corp was deemed to have nominal value on the date of the LLC Merger. Lastly, the LLC Merger was between entities under common control. As a result, the net assets assumed were at carrying value and therefore no gain (loss) was recognized upon completion of the LLC Merger.

The Company’s headquarters is located in Farmington Hills, Michigan. The Company is a clinical-stage ophthalmic biopharmaceutical company focused on developing and commercializing therapies for the treatment of several eye disorders. The Company’s pipeline currently includes two small molecule product candidates targeting front and back of the eye indications. The Company’s lead product candidate, Nyxol® Eye Drops (Nyxol), is a once-daily eye drop formulation of phentolamine mesylate designed to reduce pupil diameter and improve visual acuity. Nyxol has been studied across three Phase 1 and four Phase 2 trials totaling over 230 patients and has demonstrated promising clinical data for use in multiple ophthalmic indications. The Company plans to initiate a Phase 3 trial for the treatment of NVD and a Phase 3 trial for pharmacologically-induced mydriasis in the fourth quarter of 2020, and a Phase 2 trial in combination with low dose pilocarpine for presbyopia in the first quarter of 2021. The Company’s second product candidate, APX3330, is a twice-a-day oral tablet, designed to target multiple pathways relevant to retinal and choroidal vascular diseases, such as diabetic retinopathy (DR) and diabetic macular edema (DME). Prior to the Company’s in-licensing of the product candidate, APX3330 had been studied by third parties in six Phase 1 and five Phase 2 trials totaling over 440 patients, for inflammatory and oncology indications, and had demonstrated promising evidence of tolerability, pharmacokinetics, durability and target engagement. The Company plans to initiate a Phase 2 trial for APX3330 in the first quarter of 2021 for the treatment of moderately severe non-proliferative DR (NPDR) and mild proliferative DR (PDR), as well as patients with DME without loss of central vision. The Company has also in-licensed additional second generation product candidates, analogs of APX3330, including APX2009 and APX2014. As part of its strategy, Ocuphire will continue to explore opportunities to acquire additional ophthalmic assets and to seek strategic partners for late stage development, regulatory preparation and commercialization of drugs in key global markets.

1. Company Description and Summary of Significant Accounting Policies (continued)

The Company has sustained operating losses since inception and expects such losses to continue  indefinitely until a sustained revenue source is realized. Management plans to continue financing the operations through additional issuances of the Company’s equity and debt securities. If adequate funds are not available, the Company may be required to delay, reduce the scope of, or eliminate part or all of its research and development programs.

Reverse Merger with Rexahn

On June 17, 2020, Ocuphire, Rexahn Pharmaceuticals, Inc., a Delaware corporation (Rexahn), Razor Merger Sub, Inc., a Delaware corporation and wholly-owned subsidiary of Rexahn (Merger Sub), entered into an Agreement and Plan of Merger and Reorganization, as amended on June 29, 2020 (as amended, the Merger Agreement), pursuant to which, among other things, and subject to the satisfaction or waiver of certain conditions set forth in the Merger Agreement, Merger Sub would merge with and into Ocuphire, with Ocuphire continuing as a wholly-owned subsidiary of Rexahn and the surviving corporation of the merger (the Merger). The Merger closed on November 5, 2020.  Upon completion of the Merger, Rexahn changed its name to Ocuphire Pharma, Inc. and changed its ticker symbol on the Nasdaq Capital Market to “OCUP”.See Note 10 Subsequent Events.

Basis of Presentation

The accompanying condensed financial statements have been prepared by the Company, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission (SEC). Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (GAAP) have been condensed or omitted pursuant to such rules and regulations.

The December 31, 2019 condensed balance sheet was derived from audited financial statements, and may not include all disclosures required by GAAP; however, the Company believes that the disclosures are adequate to make the information presented not misleading. These unaudited condensed financial statements should be read in conjunction with the audited financial statements and the notes thereto for the fiscal year ended December 31, 2019.

In the opinion of management, all adjustments, consisting of only normal recurring adjustments that are necessary to present fairly the financial position, results of operations, and cash flows for the interim periods, have been made. The results of operations for the interim periods are not necessarily indicative of the operating results for the full fiscal year or any future periods.

Going Concern

The Company’s ability to continue operating as a going concern is contingent upon, among other things, its ability to secure additional financing and to achieve and maintain profitable operations. The Company plans to issue additional equity instruments to finance operating and working capital requirements. While the Company expects to obtain the additional financing that is needed, there is no assurance that the Company will be successful in obtaining the necessary funding for future operations. These factors raise substantial doubt as to the Company’s ability to continue as a going concern. The financial statements do not include any adjustments that might result from the outcome of these uncertainties.

Due to the absence of an active market for the Company’s common stock, the Company utilized methodologies in accordance with the framework of the American Institute of Certified Public Accountants’ Technical Practice Aid, Valuation of Privately-Held Company Equity Securities Issued as Compensation, to estimate the fair value of its common stock. The valuation methodology includes estimates and assumptions that require the Company’s judgment. These estimates and assumptions include a number of objective and subjective factors, including external market conditions affecting the biotechnology industry sector, and the likelihood of achieving a liquidity event, such as an initial public offering (IPO), reverse merger or sale. Significant changes to the key assumptions used in the valuations could result in different fair values of common stock at each valuation date.

For the valuation of equity awards granted in September 2020, the Company used a contemporaneous third-party valuation of $7.89 per share. For the valuation of equity awards granted in April 2020 and June 2020, the Company applied a straight-line calculation using the contemporaneous third-party valuations of $1.74 per share as of March 31, 2020 and $9.54 per share as of June 18, 2020 to determine the fair value of the Company’s common stock. Using the benefit of hindsight, the Company determined that the straight-line calculation would provide the most reasonable conclusion for the valuation of the Company’s common stock on these interim dates between valuations because the Company did not identify any single event or series of events that occurred during this interim period that would have caused a material change in fair value. Based on this calculation, the Company assessed the fair value of its common stock for awards granted in April 2020 and June 2020 at $2.33 and $8.65 per share, respectively.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.

Segment Information

Operating segments are components of an enterprise for which separate financial information is available and is evaluated regularly by the Company’s chief operating decision maker in deciding how to allocate resources and assessing performance. The Company’s chief operating decision maker is its Chief Executive Officer. The Company’s Chief Executive Officer views the Company’s operations and manages its business in one operating segment, which is the business of development and commercialization of products related to vision performance and health. Accordingly, the Company has a single reporting segment.

Cash and Cash Equivalents

The Company considers all highly liquid investments with an original maturity of 90 days or less at the time of deposit to be cash equivalents.

Concentration of Credit Risk

Financial instruments that potentially subject the Company to a concentration of credit risk consist of cash and cash equivalents. The Company’s cash is held by one financial institution in the United States. Amounts on deposit may at times exceed federally insured limits. Management believes that the financial institution is financially sound, and accordingly, minimal credit risk exists with respect to the financial institution. As of September 30, 2020, the Company had deposits that exceeded federally insured amounts by $472,258.

General and Administrative Expenses

General and administrative expenses (G&A) consist primarily of personnel-related costs, including salaries and stock-based compensation costs, for personnel in functions not directly associated with research and administrative activities. Other significant costs include legal fees relating to intellectual property and corporate matters, professional fees for accounting and tax services, and other services provided by business consultants.

1. Company Description and Summary of Significant Accounting Policies (continued)

Research and Development

Research and development expenses (R&D) consist of costs incurred in performing research and development activities, including compensation for research and development employees and consultants, costs associated with preclinical studies and clinical trials, regulatory activities, manufacturing activities to support clinical activities, license fees, nonlegal patent costs, fees paid to external service providers that conduct certain research and development, and an allocation of overhead expenses.

Acquired In‑Process Research and Development Expenses

The Company includes costs to acquire or in‑license product candidates as acquired in‑process research and development expenses (IPR&D). These costs are immediately expensed provided that the payments do not also represent processes or activities that would constitute a “business” as defined under GAAP or provided that the product candidate has not achieved regulatory approval for marketing, and absent obtaining such approval, has no alternative future use. Royalties owed on future sales of any licensed product will be expensed in the period the related revenues are recognized. See Note 8 – Apexian Sublicense Agreement.

Other (Expense) Income, net

Other expense includes non-operating transaction costs, including legal and advisory fees, related principally to potential asset acquisitions when incurred. Other income represents interest income related to cash and cash equivalent investments and reimbursements from grants and other sources. The non-operating transaction costs, interest income and other reimbursements are included in the other (expense) income, net line item in the accompanying condensed statements of comprehensive loss.

Share‑Based Compensation

The Company accounts for share‑based compensation in accordance with the provisions of the Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC 718), Compensation — Stock Compensation. Accordingly, compensation costs related to equity instruments granted are recognized at the grant‑date fair value. The Company records forfeitures when they occur. Share‑based compensation arrangements to non‑employees are accounted for in accordance with the applicable provisions of ASC 718 using a fair value approach.

Premium Conversion Derivatives

The Company evaluates all conversion and redemption features contained in a debt instrument to determine if there are any embedded derivatives that require separation from the host debt instrument. An embedded derivative that requires separation is bifurcated from its host debt instrument and a corresponding discount to the host debt instrument is recorded. The discount is amortized and recorded to interest expense over the term of the host debt instrument using the straight-line method which approximates the effective interest method. The embedded derivative is accounted for separately on a fair market value basis. The Company records the fair value changes of a separated embedded derivative at each reporting period in the fair value change in premium conversion derivatives line item in the accompanying condensed statements of comprehensive loss. The Company determined that the redemption features under the convertible notes qualified as embedded derivatives and were separated from their debt hosts.

Fair Value Measurements

The Company follows accounting guidance that emphasizes that fair value is a market-based measurement, not an entity-specific measurement. Fair value is defined 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.” Fair value measurements are defined on a three-level hierarchy:

12

Ocuphire Pharma, Inc.

Notes to condensed financial statements (unaudited), continued

1. Company Description and Summary of Significant Accounting Policies (continued)

• Level 1 inputs: Unadjusted quoted prices for identical assets or liabilities in active markets;

• Level 2 inputs: Quoted prices for similar assets and liabilities in active markets, quoted prices in markets that are not active, or inputs which are observable, whether directly or indirectly, for substantially the full term of the asset or liability; and

• Level 3 inputs: Unobservable inputs that reflect the Company’s own assumptions about the assumptions market participants would use in pricing the asset or liability in which there is little, if any, market activity for the asset or liability at the measurement date.

As of September 30, 2020 and December 31, 2019, the fair values of cash, prepaid and other assets, deferred costs, accounts payable and accrued expenses approximated their carrying values because of the short-term nature of these assets or liabilities. The estimated fair value of the Company’s convertible notes was based on amortized cost which was deemed to approximate fair value. The fair value of the premium conversion derivatives was based on cash flow models discounted at current implied market rates evidenced in recent arms-length transactions representing expected returns by market participants for similar instruments and are based on Level 3 inputs. There were no transfers between fair value hierarchy levels during the three and nine months ended September 30, 2020 and 2019.

The fair value of financial instruments measured on a recurring basis is as follows:

	As of September 30, 2020
Description	Total		Level 1		Level 2		Level 3
Liabilities:
Premium conversion derivatives	$	300,378	$	—	$	—	$	300,378
Total liabilities at fair value	$	300,378	$	—	$	—	$	300,378

	As of December 31, 2019
Description	Total		Level 1		Level 2		Level 3
Liabilities:

Total liabilities at fair value	$	2,713,668	$	—	$	—	$	2,713,668

The following table provides a roll-forward of the premium conversion derivatives measured at fair value on a recurring basis using unobservable level 3 inputs for the nine months ended September 30, 2020 and 2019:

There were no financial instruments measured on a non-recurring basis for any of the periods presented.

Income Taxes

The Company utilizes the liability method of accounting for income taxes as required by ASC 740, Income Taxes. Under this method, deferred tax assets and liabilities are determined based on differences between financial reporting and the tax basis of assets and liabilities and are measured using enacted tax rates and laws that will be in effect when the differences are expected to reverse. Currently, there is no provision for income taxes, as the Company has incurred operating losses to date, and a full valuation allowance has been provided on its net deferred tax assets. The LLC was treated as a partnership for federal and state income tax purposes. Accordingly, no provision with regard to the LLC’s operations was made for income taxes for periods prior to the LLC Merger.

Property and Equipment, net

Property and equipment, net is recorded at cost and reduced by accumulated depreciation. Depreciation expense is recognized over the estimated useful lives of the assets using the straight-line method. Equipment and furniture is depreciated over a five year estimated useful life. Tangible assets acquired for research and development activities which have alternative use are capitalized and depreciated over the useful life of the acquired asset. Estimated useful lives are periodically reviewed, and when appropriate, changes are made prospectively. When certain events or changes in operating conditions occur, asset lives may be adjusted and an impairment assessment may be performed on the recoverability of the carrying amounts. Maintenance and repairs are charged directly to expense as incurred.

Recent Accounting Pronouncements

In May 2014, the FASB issued Accounting Standards Update (ASU) 2014‑09, Revenue from Contracts with Customers (Topic 606), which supersedes the revenue recognition requirements in FASB ASC 605. The new guidance primarily states that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods and services. The Company adopted this standard on January 1, 2019 and selected the modified retrospective transition method. The Company modified its accounting policies to reflect the requirements of this standard; however, the adoption did not affect the Company’s financial statements and related disclosures for the periods presented as the Company has yet to generate any revenues.

In January 2016, the FASB issued ASU No. 2016‑01, Financial Instruments — Overall: Recognition and Measurement of Financial Assets and Financial Liabilities. The guidance affects the accounting for equity investments, financial liabilities under the fair value option and the presentation and disclosure requirements of financial instruments. The guidance is effective in 2019 for private entities. The Company adopted this standard on January 1, 2019 and the standard did not have a material impact on the Company’s financial statements.

In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash. The objective of this ASU is to eliminate the diversity in practice related to the classification of restricted cash or restricted cash equivalents in the statement of cash flows. This ASU is effective for annual reporting periods beginning after December 15, 2018 for private entities, with early adoption permitted. The amendments in this update should be applied retrospectively to all periods presented. The Company adopted this standard on January 1, 2019 and the standard did not have a material impact on the Company’s financial statements.

In June 2018, the FASB issued ASU 2018-07, Compensation - Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting (ASU 2018-07), which expands the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from nonemployees. An entity should generally apply the requirements of Topic 718

to nonemployee awards except in circumstances where there is specific guidance on inputs to an option pricing model and the attribution of cost. ASU 2018-07 specifies that Topic 718 applies to all share-based payment transactions in which a grantor acquires goods or services to be used or

consumed in a grantor’s own operations by issuing share-based payment awards. This guidance is effective for annual reporting periods beginning after December 15, 2019, with early adoption permitted, but no earlier than an entity’s adoption date of ASC 606. The Company early adopted ASU 2018-07 effective January 1, 2019. The guidance did not have an impact to the Company’s financial statements.

In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement (ASU 2018-13). This new guidance modifies the disclosure requirements on fair value measurements, including removal and modifications of various current disclosures as well as some additional disclosure requirements for Level 3 fair value measurements. Some of these disclosure changes must be applied prospectively while others retrospectively depending on requirement. This guidance is required to be adopted by the Company beginning in fiscal year 2020 with early adoption permitted. The Company adopted the new guidance on January 1, 2020 and the adoption did not have an impact on its financial statements.

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) and subsequently amended the guidance relating largely to transition considerations under the standard in January 2017, July 2018 and March 2019. The objective of this update is to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. The Company adopted the new guidance on January 1, 2019 and the adoption did not have an impact on its financial statements.

In July 2017, the FASB issued ASU No. 2017-11, Earnings Per Share, Distinguishing Liabilities from Equity and Derivatives and Hedging, which changes the accounting and earnings per share for certain instruments with down round features. The amendments in this ASU should be applied using a cumulative-effect adjustment as of the beginning of the fiscal year or retrospective adjustment to each period presented. The Company adopted the new guidance on January 1, 2020 and the adoption did not have an impact on its financial statements.

The FASB issued ASU 2019-12, Income Taxes (Topic 740) - Simplifying the Accounting for Income Taxes. The new guidance simplifies the accounting for income taxes by eliminating certain exceptions related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period, hybrid taxes and the recognition of deferred tax liabilities for outside basis differences. It also clarifies and simplifies other aspects of the accounting for income taxes. For private entities, the amendments in this ASU are effective for fiscal years beginning after December 15, 2021 and interim periods within those fiscal years. Early adoption is permitted in interim or annual periods with any adjustments reflected as of the beginning of the annual period that includes that interim period. Additionally, entities that elect early adoption must adopt all the amendments in the same period. Amendments are to be applied prospectively, except for certain amendments that are to be applied either retrospectively or with a modified retrospective approach through a cumulative effect adjustment recorded to retained earnings. The Company adopted the guidance effective April 1, 2020. The adoption of the guidance did not have a material impact on the Company’s financial statements.

In August 2020, FASB issued ASU 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity, which, among other things, provides guidance on how to account for contracts on an entity’s own equity. This ​ASU eliminates the beneficial conversion and cash conversion accounting models for convertible instruments. It also amends the accounting for certain contracts in an entity’s own equity that are currently accounted for as derivatives because of specific settlement provisions. In addition, this ASU modifies how particular convertible instruments and certain contracts that may be settled in cash or shares impact the diluted EPS computation. The amendments in this ASU are effective for private entities and smaller reporting companies (as defined by the SEC) for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years. Early adoption is permitted, but no earlier than fiscal years beginning after December 15, 2020. The Company is currently evaluating the impact of ASU 2020-06 on its  financial statements.

Apexian Sublicense Agreement

On January 21, 2020, the Company entered into a sublicense agreement with Apexian Pharmaceuticals, Inc., pursuant to which it obtained exclusive worldwide patent and other intellectual property rights. In exchange for the patent and other intellectual rights, the Company agreed to certain milestone and royalty payments on future sales (See Note 8 — Apexian Sublicense Agreement). As of September 30, 2020, there was sufficient uncertainty with regard to both the outcome of the clinical trials and the ability to obtain sufficient funding to support any of the cash milestone payments under the sublicense agreement, and as such, no liabilities were recorded related to the sublicense agreement.

Facility Lease

In May 2019, the Company entered into a short term non-cancellable facility lease (the Lease) for its operations and headquarters for a seven-month term beginning in June 2019. In October 2019, the Lease was amended to extend the term to December 31, 2020. The monthly base rent is approximately $2,975. See Note 10 – Subsequent Events.

The rent expense associated with the Lease amounted to $12,114 and $30,244 during the three and nine months ended September 30, 2020, respectively, and $8,502 and $10,783 during the three and nine months ended September 30, 2019.

Pre-Merger Financing

Securities Purchase Agreement

On June 17, 2020, Ocuphire, Rexahn and certain investors (the Investors) entered into a Securities Purchase Agreement (the Original Securities Purchase Agreement), which was amended and restated in its entirety on June 29, 2020 (as amended and restated, the Securities Purchase Agreement).  Pursuant to the Securities Purchase Agreement, the Investors agreed to invest a total of $21.15 million in cash, inclusive of the commitment by the Company’s directors to invest $1.15 million, (the Purchase Price and the financing arrangement described herein, the Pre-Merger Financing) to fund the combined company following the Merger (the Combined Company). In return, based on an agreed upon pre-money valuation of the Combined Company following the Merger of $120 million, Ocuphire agreed to issue an amount of shares (the Initial Shares) of Ocuphire common stock, par value $0.0001 (the Ocuphire Common Stock) to the Investors, which shares were to be exchangeable in the Merger for approximately 15% of the Pre-Merger Financing fully diluted shares. In addition, (i) Ocuphire agreed to deposit three times the number of Initial Shares of Ocuphire Common Stock (the Additional Shares, and together with the Initial Shares the Pre-Merger Financing Shares) into escrow with an escrow agent for the benefit of the Investors, to be exchanged for Rexahn common stock in the Merger, and to be delivered, in whole or in part, based on the formula set forth below, out of escrow to the Investors if 85% of the average of the five lowest volume-weighted average trading prices of a share of Rexahn common stock on the Nasdaq Capital Market (Nasdaq) during the first ten trading days (or earlier at the election of any Investor) immediately following the closing date of the Pre-Merger Financing (which closing date will be the same date as the Closing of the Merger) is lower than the effective price per share paid by the Investors for the number of shares of Rexahn common stock issued to the Investors at the Effective Time in exchange for the Initial Shares (the “Converted Initial Shares”), and (ii) on the tenth trading day following the closing date of the Pre-Merger Financing (the Warrant Closing Date), Rexahn will issue to the Investors (x) Series A warrants to purchase shares of Rexahn common stock, as further described below (the Series A Warrants) and (y) Series B warrants to purchase shares of Rexahn common stock, as further described below (the Series B Warrants, together with the Series A Warrants, the Investor Warrants”).

Series A Warrants

The Series A Warrants will be issued on the Warrant Closing Date, will have an initial exercise price per share equal to 120% of the per share Final Purchase Price, will be immediately exercisable and will have a term of five years from the date of issuance. The Series A Warrants issued to each Investor will initially be exercisable for an amount of Rexahn common stock equal to the sum of (i) the number of Converted Initial Shares issued to the Investor, (ii) the number of shares of Rexahn common stock issued to the escrow agent at such time in exchange for the Additional Shares (the Converted Additional Shares) delivered or deliverable to the Investor as of the Warrant Closing Date and (iii) the number of shares, if any, underlying the Series B Warrants held by the Investor as of the Warrant Closing Date.

The Series A Warrants provide that, until the second anniversary of the date on which all shares of Rexahn common stock issued and issuable to the Investors (including any shares underlying the Investor Warrants) (the Underlying Securities) may be sold without restriction or limitation pursuant to Rule 144 (provided that the combined company satisfies the current public information requirements under Rule 144(c), and if it does not satisfy such requirements (a Public Information Failure), the second anniversary of such later date on which the Public Information Failure is cured and no longer prevents the Investors from selling all of the Underlying Securities), if Rexahn publicly announces, issues or sells, enters into a definitive, binding agreement pursuant to which Rexahn is required to issue or sell or is deemed, pursuant to the provisions of the Series A Warrants, to have issued or sold, any shares of Rexahn common stock for a price per share lower than the exercise price then in effect, subject to certain limited exceptions, then the exercise price of the Series A Warrants will be reduced to such lower price per share. Further, on each Reset Date (as defined below) the Series A Warrants will be adjusted downward (but not increased) such that the exercise price thereof becomes 120% of the Reset Price (as defined below), and the number of shares underlying the Series A Warrants will be increased (but not decreased) to the quotient of (a) (i) the exercise price in effect prior to such Reset (as defined below) multiplied by (ii) the number of shares underlying the Series A Warrants prior to the Reset divided by (b) the resulting exercise price. In addition, the exercise price and the number of shares of Rexahn common stock issuable upon exercise of the Series A Warrants will also be subject to adjustment in the event of any stock splits, dividends or distributions or other similar transactions.

Other

In the ordinary course of business, from time to time, the Company may be subject to a broad range of claims and legal proceedings that relate to contractual allegations, patent infringement and other claims. In addition, the Company from time to time may be potentially committed to reimburse third parties for costs incurred associated with business development related transactions upon the achievement of certain milestones. The Company establishes accruals when applicable for matters and commitments which it believes losses are probable and can be reasonably estimated. To date, no loss contingency for such matters and potential commitments have been recorded. Although it is not possible to predict with certainty the outcome of these matters or potential commitments, the Company is of the opinion that the ultimate resolution of these matters and potential commitments will not have a material adverse effect on its results of operations or financial position.

4. Convertible Notes

The Company entered into a series of convertible note financings (the Convertible Notes) with certain investors beginning on May 25, 2018. The total issuance of Convertible Notes through September 30, 2020 amounted to $8,472,500 (see Note 5 – Related Party Transactions).

On June 8, 2020, the Company amended the Convertible Notes (the Conversion Agreement). Under the Conversion Agreement, upon such date selected by the Company following Rexahn’s receipt of the required Rexahn stockholder vote and prior to the effectiveness of the Merger, each Convertible Note shall automatically and without any action required by any purchaser or the Company be cancelled and, simultaneously with such cancellation, convert into that number of fully paid and non-assessable shares of the Company’s common stock that is equal to 175% times  the outstanding principal and accrued but unpaid interest (Note Value) divided by the conversion price (the Conversion Price), rounded to the nearest whole share. The Conversion Price has the meaning of the per share price resulting from the quotient of (1) $100,000,000 less the aggregate amount of 175% times the Note Value of all of the Convertible Notes divided by (2) the fully diluted shares (the Fully Diluted Shares). Fully Diluted Shares has the meaning of: (1) all of the issued outstanding shares of the Company’s common stock; and (2) the aggregate number of shares of the Company’s common stock reserved for issuance under all outstanding options or other awards under equity incentive plans of the Company in effect as of such date of determination.

The addition of the new conversion feature under the Conversion Agreement represented a substantial modification to the Convertible Notes, and as such, the Company recorded the modification as a note extinguishment. On the modification date, the fair value of the Convertible Notes (inclusive of the embedded features) was $1,260,350 lower upon modification than the aggregate of the carrying value of the Convertible Notes and the fair value of the embedded features; the difference was recorded as a gain on note extinguishment in the accompanying condensed statements of comprehensive loss for the nine months ended September 30, 2020.

4. Convertible Notes (continued)

Lastly, an increase to additional paid-in capital in the amount of $970,628 was recorded in connection with the Conversion Agreement to account for the excess of the Convertible Notes’ fair value over the aggregate value of outstanding note principal, accrued interest and fair value of the premium conversion derivatives upon execution of the Conversion Agreement. See Note 10 – Subsequent Events.

Previous to the Conversion Agreement, the Convertible Notes were amended on January 22, 2019 and again on November 20, 2019. The January 2019 amendment was accounted for as a note modification for financial accounting purposes. The modification resulted in an additional discount to the Convertible Notes in the amount of $58,837 with a corresponding increase to the premium conversion derivative liability.

The Convertible Notes accrue interest at a rate of 8% per annum, calculated on a 365-day year basis. Interest expense on principal during the three and nine months ended September 30, 2020 was $170,843 and $477,427, respectively, and $104,000 and $189,790 during the three and nine months ended September 30, 2019, respectively.

The outstanding principal of, and accrued interest on the Convertible Notes were payable on demand, in the absence of the Merger closing discussed above, at any time as of the first to occur of (i) September 30, 2020 or (ii) an event of default (each defined by the Convertible Notes as a Payoff Event). If, prior to a Payoff Event, the Company (i) completed an initial public offering (IPO), (ii) completed a change in control (CIC), (iii) completed a sale and issuance of its capital stock resulting in gross proceeds to the Company of at least $5 million (Qualified Financing), or (iv) completed a reverse merger transaction (Reverse Merger), then the outstanding principal of, and accrued but unpaid interest on the Convertible Notes would have automatically converted upon the earliest of such events to occur as follows:

• IPO: The Convertible Notes would have automatically converted into the number of fully paid and non-assessable shares of the Company’s common stock equal to One Hundred and Seventy-Five Percent (175%) times Note Value divided by the per share price such shares were issued to purchasers of the Company’s equity securities in the IPO rounded to the nearest whole share.

• CIC: The Convertible Notes would have automatically converted  prior to the effectiveness of such CIC into that number of fully paid and non-assessable shares of the Company’s common stock equal to Two Hundred Percent (200%) of the Note Value divided by the per share price of the Company’s common stock at which the Company’s common stock was valued in such CIC (after giving effect to such conversion). The Convertible Note holder would have been entitled to the same contractual rights and would have been bound by the same restrictions and obligations as the other stockholders of the Company in such CIC.

4. Convertible Notes (continued)

• Qualified Financing: The Convertible Notes would have automatically converted into that number of fully paid and non-assessable shares of the Company that were issued by the Company in the Qualified Financing, determined by dividing an amount equal to One Hundred and Seventy-Five Percent (175%) times the Note Value by the per share price such shares of the Company were issued to purchasers of the Company’s equity securities in the Qualified Financing, rounded to the nearest whole share. The Convertible Note holder would have been  entitled to the same contractual rights and would have been bound by the same restrictions and obligations as the other purchasers of shares in the Qualified Financing. A Qualified Financing was defined as a sale and issuance of capital stock of the Company (or its successor) in a single transaction or series of related transactions resulting in gross proceeds to the Company of not less than $5,000,000 (including new equity investment of at least $1,000,000 plus the sum of the outstanding principal amount of the Convertible Notes being so converted under this provision).

• Reverse Merger (excluding close of Merger with Rexahn): The Convertible Notes would have automatically converted into that number of fully paid and non-assessable shares of the Combined Company whose shares were publicly traded in the United States or other jurisdiction following the completion of the Reverse Merger (the Reverse Merger Parent), determined by dividing an amount equal to One Hundred and Seventy-Five Percent (175%) times the Note Value divided by the per share price at which such shares were issued by the Reverse Merger Parent in such Reverse Merger, rounded to the nearest whole share. The Convertible Note holder would have been entitled to the same contractual rights and would have been bound by the same restrictions and obligations as the other stockholders of the Company in the Reverse Merger.

The Company was not permitted to prepay the Convertible Notes prior to a Payoff Event. The Convertible Notes contained default provisions, and when triggered, the holders of the Convertible Notes could have immediately accelerated payment of the Convertible Notes and the outstanding principal and interest would have become payable immediately. During a period of default, interest would have been assessed at a 12% per annum rate.

Redemption Features

The Company determined that all of the conversion provisions, except for the conversion provision upon Merger close, were redemption features that qualified as embedded derivatives. The qualifying embedded derivatives were collectively separated from their debt host upon the issuance of the Convertible Notes. The bifurcation of the embedded derivatives from the debt host resulted in a discount to the Convertible Notes in the amount of zero and $831,172 during the three and nine months ended September 30, 2020, respectively, and zero and $1,099,609 during the three and nine month periods ended September 30, 2019, respectively. The embedded derivatives were accounted for separately on a fair market value basis. The fair value of the derivatives was $300,378 and $2,713,668 at September 30, 2020 and December 31, 2019, respectively, and was included in the premium conversion derivatives line item on the accompanying condensed balance sheets. The Company recorded the fair value changes of the premium conversion derivatives to the fair value change line item in the accompanying condensed statements of comprehensive loss which amounted to a benefit of  $(879,386) and $(157,942) during the three and nine months ended September 30, 2020, respectively, and an expense of $29,592 and $161,675 during the three and nine months ended September 30, 2019, respectively.

4. Convertible Notes (continued)

The Company recorded a discount to the Convertible Notes, attributed to both third party costs in connection with the note extinguishment and note issuance costs, of zero and $10,495 during the three and nine months ended September 30, 2020, respectively, and zero and $1,698 associated with note issuance costs during the three and nine month periods ended September 30, 2019, respectively.

The note discounts were amortized to interest expense over the term of the Convertible Notes using the straight-line method which approximates the effective interest method and amounted to $8,205 and $944,245 during the three and nine months ended September 30, 2020, respectively, and $514,692 and $748,771 during the three and nine months ended September 30, 2019, respectively.

5. Related Party Transactions

The Company incurred consulting expenses from one officer who is also a board member in the amount of zero and $29,222 during the three and nine months ended September 30, 2019, respectively. There were no consulting expenses from any officer during the three and nine month period ended September 30, 2020. None of the consulting expenses to the officer were unpaid as of September 30, 2020 and December 31, 2019.

Convertible Notes with Related Parties

The Company entered into Convertible Notes with certain investors beginning on May 25, 2018. Through September 30, 2020, Convertible Notes in the principal aggregate amount equal to $747,086 were issued to four board members and to two officers, one of which was also a board member of the Company. See Note 4 – Convertible Notes.

Apexian Sublicense Agreement

The Company entered into a sublicense agreement with Apexian Pharmaceuticals, Inc. (Apexian) and issued a total of 843,751 shares of common stock to Apexian and to certain affiliates of Apexian.  See Note 8 – Apexian Sublicense Agreement.

6. Share-based Compensation

Share-based compensation expense was included in general and administrative and research and development costs as follows in the accompanying condensed statements of comprehensive loss for the periods indicated below:

	Three Months Ended September 30,				Nine Months Ended September 30,
	2020		2019		2020		2019
General and administrative	$	224,120	$	42,735	$	425,581	$	132,960

Total share-based compensation	$	615,358	$	73,305	$	993,146	$	229,791

Stock Options

In April 2018, the Company adopted a 2018 Equity Incentive Plan (the 2018 Plan) under which 1,175,000 shares of the Company’s common stock were reserved for issuance to employees, directors, and consultants upon the amendment of the 2018 Plan in December 2019. The 2018 Plan permits the grant of incentive and non‑statutory stock options, appreciation rights, restricted stock, restricted stock units, performance stock and cash awards, and other share‑based awards. During the three and nine months ended September 30, 2020, 21,200 and 221,481 stock options to consultants and employees were granted, respectively, generally vesting over a twelve (12) to twenty-eight (28) month period. During the three and nine month periods ended September 30, 2019, 29,000 and 76,500 stock options to consultants were granted, respectively, generally vesting over a twelve (12) month period. The share-based compensation expense attributed to the stock options during the three and nine months ended September 30, 2020 was $615,358 and $993,146, respectively. The share-based compensation expense attributed to the stock options during the three and nine month periods ended September 30, 2019 was $73,305 and $206,152, respectively.

The weighted average fair value per share of options granted during the three and nine months ended September 30, 2020 was $6.63 and $6.35, respectively. The weighted average fair value per share of options granted during the three and nine month periods ended September 30, 2019 was $0.89 and $0.81, respectively. The Company measures the fair value of stock options with service‑based and performance‑based vesting criteria to employees, consultants and directors on the date of grant using the Black‑Scholes option pricing model. The Company does not have history to support a calculation of volatility and expected term. As such, the Company has used a weighted‑average volatility considering the volatilities of several guideline companies.

For purposes of identifying similar entities, the Company considered characteristics such as industry, length of trading history, and stage of life cycle. The assumed dividend yield was based on the Company’s expectation of not paying dividends in the foreseeable future. The average expected life of the options was determined in accordance with the “simplified method” as described in SEC Staff Accounting Bulletin 110, where appropriate, or based on the contractual term of the grant agreement. The risk‑free interest rate is determined by reference to implied yields available from U.S. Treasury securities with a remaining term equal to the expected life assumed at the date of grant. The Company records forfeitures when they occur.

6. Share-based Compensation (continued)

The weighted‑average assumptions used in the Black‑Scholes option‑pricing model are as follows during the three and nine months ended September 30:

	Three Months Ended						Nine Months Ended
	September 30,						September 30,
	2020			2019			2020			2019
Expected stock price volatility		87.6	%		87.2	%		94.8	%		86.0	%
Expected life of options (years)		10.0			5.3			10.0			5.3
Expected dividend yield		0	%		0	%		0	%		0	%
Risk free interest rate		0.7	%		1.6	%		0.7	%		1.9	%

During the three and nine months ended September 30, 2020, 178,175 and 255,031 stock options vested, respectively. During the three and nine months ended September 30, 2019, 108,736 and 309,108 stock options vested, respectively. During the three and nine months ended September 30, 2020, 21,200 and 28,700 were forfeited, respectively.  No stock options were forfeited during the three and nine month period ended September 30, 2019.

Restricted Stock Awards

The Company did not grant any restricted stock awards (RSAs) during the three and nine months ended September 30, 2020 and 2019. The RSAs granted in fiscal 2018 were subject to various vesting schedules. A portion of the RSAs vested immediately upon issue with the remainder of shares generally vested ratably over a two (2) to twelve (12) month period coinciding with their respective service period requirements.  During the three and nine month periods ending September 30, 2019, zero and 61,100 RSAs vested, respectively. The RSAs were all fully vested as of September 30, 2019. No RSAs were forfeited during the periods presented. The share-based compensation expense attributed to the RSAs during the three and nine months ended September 30, 2019 was zero and $23,639, respectively.

As of September 30, 2020, no shares were available for future issuance under the 2018 Plan. Unrecognized share‑based compensation cost was $1,139,222 as of September 30, 2020. The unrecognized share‑based expense is expected to be recognized over a weighted average period of 0.8 years.

7. Income Taxes

The effective tax rate for the three and nine months ended September 30, 2020 and 2019 was zero percent.

As of September 30, 2020 and December 31, 2019, a full valuation allowance has been established to reduce the Company’s net deferred income tax assets. As such, no tax benefit related to the Company’s pre-tax loss was recognized for any of the periods presented.

The Company’s corporate returns are subject to examination for the 2018 tax years for federal income tax purposes and subject to examination for the 2018 tax years in one state jurisdiction. Prior to these periods, the Company filed partnership returns, resulting in its income being passed through to its members. The Company does not have any reserves for income taxes that represent the Company’s potential liability for uncertain tax positions.

8.  Apexian Sublicense Agreement

On January 21, 2020, as amended on June 4, 2020, the Company entered into a sublicense agreement (the Sublicense Agreement) with Apexian, a related party, pursuant to which it obtained exclusive worldwide patent and other intellectual property rights that constitute a Ref-1 Inhibitor program relating to therapeutic applications to treat disorders related to ophthalmic and diabetes mellitus conditions. The lead compound in the Ref-1 Inhibitor program is APX3330, which the Company intends to develop as an oral pill therapeutic to treat diabetic retinopathy and diabetic macular edema initially, and potentially later to treat wet age-related macular degeneration.

In connection with the Sublicense Agreement, the Company issued a total of 843,751 shares of its common stock to Apexian, a related party, and to certain affiliates of Apexian. The share issuance transaction was recorded in the amount of $2,126,253 as IPR&D expense based on the fair market value of the common shares issued since no processes or activities that would constitute a “business” were acquired and none of the rights and underlying assets acquired had alternative future uses or reached a stage of technological feasibility. In addition, the Company shall pay any balance remaining of $400,000 of Ref-1 Inhibitor program costs to Apexian following the Company’s listing on a major stock exchange.

The Company also agreed to make one-time milestone payments under the Sublicense Agreement for each of the first ophthalmic indication and the first diabetes mellitus indication for the Development and Regulatory milestones, and once for each of the Sales milestones. These milestone payments include (i) payments for specified developmental and regulatory milestones (including completion of the first Phase 2 trial and the first Phase 3 pivotal trial in the United States, and filing and achieving regulatory approval from the FDA for the first New Drug Application for a compound) totaling up to $11 million in the aggregate and (ii) payments for specified sales milestones of up to $20 million in the aggregate, which net sales milestone payments are payable once, upon the first achievement of such milestone. Lastly, the Company also agreed to make a royalty payment equal to a single-digit percentage of its net sales of products associated with the covered patents under the Sublicense Agreement.

8.  Apexian Sublicense Agreement (continued)

Beginning on December 31, 2020, if the Company has not (i) listed shares of its capital stock on a major stock exchange or (ii) completed a reverse merger or similar transaction with a corporation whose securities are listed on a major stock exchange, either the Company or Apexian may terminate the Sublicense Agreement. In the event of such termination, Apexian and its affiliates would forfeit their shares of the Company’s common stock and the Company’s intellectual property rights under the Sublicense Agreement would terminate. If it is not terminated pursuant to its terms, the Sublicense Agreement shall remain in effect until expiration of the last to expire of the covered patents.

None of the milestone or royalty payments were triggered as of September 30, 2020. See Note 10 – Subsequent Events.

9. Net loss per share

Basic loss per share of common stock is computed by dividing net loss by the weighted average number of shares of common stock outstanding during the period. Diluted earnings or loss per share of common stock is computed similarly to basic earnings or loss per share except the weighted average shares outstanding are increased to include additional shares from the assumed exercise of any common stock equivalents, if dilutive. The Company’s convertible notes, restricted stock awards and stock options, while outstanding, are considered common stock equivalents for this purpose. Diluted earnings is computed utilizing the treasury method for the restricted stock awards and stock options. Diluted earnings with respect to the convertible notes utilizing the if-converted method was not applicable during the periods presented as no conditions required for conversion had occurred. No incremental common stock equivalents were included in calculating diluted loss per share because such inclusion would be anti-dilutive given the net loss reported for the periods presented.

The following potential common shares were not considered in the computation of diluted net loss per share as their effect would have been anti-dilutive for the three and nine month periods ended September 30 presented below:

10. Subsequent Events

Ocuphire evaluated the impact of subsequent events through December 30, 2020, which is the date the financial statements were available to be issued.

Merger

On November 5, 2020, the Company completed its business combination with Rexahn in accordance with the terms of the Merger Agreement. Immediately after the Merger, there were approximately 7,091,878 shares of the Company’s common stock, par value $0.0001 per share (the Common Stock), outstanding (not including 3,749,992 Additional Shares under the Securities Purchase Agreement that were held in escrow subject to final adjustment). The former stockholders and optionholders of Ocuphire (including the Investors under the Securities Purchase Agreement) owned, or held rights to acquire, in the aggregate approximately 86.6% of the fully-diluted Common Stock, which for these purposes is defined as the outstanding Common Stock, plus outstanding options of the Company, and not including any Additional Shares (the Fully-Diluted Common Stock), with the former Rexahn stockholders immediately prior to the Merger owning approximately 13.4% of the Fully-Diluted Common Stock. Pursuant to the Merger Agreement, the number of shares of Common Stock issued to Ocuphire’s stockholders for each share of Ocuphire’s common stock outstanding immediately prior to the Merger was calculated using an Exchange Ratio of approximately 1.0565 shares of Common Stock for each share of Ocuphire common stock.

Contingent Value Rights Agreement

On November 5, 2020, in connection with the Merger, the Company, Shareholder Representatives Services LLC, as representative of the Rexahn stockholders prior to the Merger, and Olde Monmouth Stock Transfer Co., Inc., as the rights agent, entered into a Contingent Value Rights Agreement (the CVR Agreement).

Pursuant to the Merger Agreement and the CVR Agreement, Rexahn stockholders of record as of immediately prior to the Effective Time received one contingent value right (CVR) for each share of Rexahn Common Stock held.

Each CVR entitles such holders to receive, for each calendar quarter (each, a CVR Payment Period) during the 15-year period after the Closing (the CVR Term), an amount equal to the following:

10. Subsequent Events (continued)

• 90% of all payments received by Rexahn or its affiliates during such CVR Payment Period from or on behalf of BioSense Global LLC (BioSense) pursuant to that certain License and Assignment Agreement, dated as of February 25, 2019, by and between BioSense and Rexahn, as amended by Amendment No. 1, dated August 24, 2019, and as further amended by Amendment No. 2, dated March 10, 2020, minus certain permitted deductions;

• 90% of all payments received by Rexahn or its affiliates during such CVR Payment Period from or on behalf of Zhejiang HaiChang Biotechnology Co., Ltd. (HaiChang) pursuant to that certain Exclusive License Agreement, dated as of February 8, 2020, by and between HaiChang and Rexahn, minus certain permitted deductions; and

• 75% of the sum of (i) all cash consideration paid by a third party to Rexahn or its affiliates during the applicable CVR Payment Period in connection with the grant, sale or transfer of rights to Rexahn’s pre-Closing intellectual property (other than a grant, sale or transfer of rights involving a sale or disposition of the post-Merger combined company) that is entered into during the 10-year period after the Closing (Parent IP Deal), plus (ii) with respect to any non-cash consideration received by Rexahn or its affiliates from a third party during the applicable CVR Payment Period in connection with any Parent IP Deal, all amounts received by Rexahn and its affiliates for such non-cash consideration at the time such non-cash consideration is monetized by Rexahn or its affiliates, minus (iii) certain permitted deductions.

The CVRs are not transferable, except in certain limited circumstances, will not be certificated or evidenced by any instrument, will not accrue interest and will not be registered with the SEC or listed for trading on any exchange. The CVR Agreement will continue in effect until the later of the end of the CVR Term and the payment of all amounts payable thereunder.

Pre-Merger Financing

On November 5, 2020, the Company completed the previously announced Pre-Merger Financing and received gross proceeds of approximately $21,150,000.  At the closing of the Pre-Merger Financing, (i) Ocuphire issued to the Investors shares of Ocuphire common stock (the “Initial Shares” and, as converted pursuant to the Exchange Ratio in the Merger into the right to receive approximately 1,249,996 shares of common stock, the “Converted Initial Shares”) and (ii) Ocuphire deposited into an escrow account three times the number of Initial Shares of Ocuphire common stock (the Additional Shares), and, as converted pursuant to the Exchange Ratio in the Merger into the right to receive approximately 3,749,992 shares of Common Stock for the benefit of the Investors if 85% of the average of the five lowest volume-weighted average trading prices of a share of Common Stock as quoted on the Nasdaq Capital Market during the first ten trading days (or such shorter period elected by an Investor) immediately following the closing date of the Pre-Merger Financing is lower than the effective price per share paid by the Investors for the Converted Initial Shares.  The 3,749,992 Additional Shares were delivered (or became deliverable) to the Investors on November 19, 2020.

EX-99.4

Exhibit 99.4

UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

The unaudited pro forma condensed combined financial information gives effect to the Rexahn Reverse Stock Split.

On November 5, 2020,  Ocuphire Pharma, Inc., formerly known as  Rexahn Pharmaceuticals, Inc. (“Rexahn” and combined with Ocuphire on a post-closing basis, the “Company”),  completed its business combination with the private entity formally known as Ocuphire Pharma, Inc. (“Ocuphire”), in accordance with the terms of the Agreement and Plan of Merger and Reorganization, as amended on June 29, 2020 (the “Merger Agreement”) by and among Rexahn, Ocuphire and Razor Merger Sub, Inc., a Delaware corporation and wholly-owned subsidiary of Rexahn (“Merger Sub”), pursuant to which, among other things, Merger Sub merged with and into Ocuphire, with Ocuphire continuing as a wholly-owned subsidiary of the Company and the surviving corporation of the merger (the “Merger”).

The following unaudited pro forma condensed combined financial information was prepared using the acquisition method of accounting under U.S. generally accepted accounting principles (“GAAP”). For accounting purposes, Ocuphire is considered to be the acquirer of Rexahn and the Merger is expected to be accounted for as an asset acquisition. Ocuphire is considered the accounting acquirer even though Rexahn was the issuer of the common stock in the merger. To determine the accounting for this transaction under GAAP, a company must assess whether an integrated set of assets and activities should be accounted for as an acquisition of a business or as an asset acquisition. The guidance requires an initial screen test to determine if substantially all of the fair value of the gross assets acquired is concentrated in a single asset or group of similar assets. If that screen is met, the assets are not a business. In connection with the acquisition of Rexahn, substantially all of the fair value is concentrated in IPR&D and, as such, the acquisition is expected to be treated as an asset acquisition.

The unaudited pro forma condensed combined balance sheet data assume that the Merger took place on September 30, 2020 and combine the historical balance sheets of Rexahn and Ocuphire as of such date. The unaudited pro forma condensed combined statement of operations for the year ended December 31, 2019 and the nine months ended September 30, 2020 assumes that the Merger took place as of January 1, 2019 and combines the historical results of Rexahn and Ocuphire for the year ended December 31, 2019 and the nine months ended September 30, 2020. The unaudited pro forma condensed combined financial information was prepared in accordance with GAAP and pursuant to the rules and regulations of Article 11 of SEC Regulation S-X. The historical financial statements of Rexahn and Ocuphire have been adjusted to give pro forma effect to events that are (i) directly attributable to the transaction, (ii) factually supportable, and (iii) with respect to the unaudited pro forma condensed combined statements of operations, expected to have a continuing impact on the combined company’s results.

Rexahn’s assets and liabilities will be measured and recognized at their relative fair values allocation as of the transaction date with any value associated with IPR&D being expensed as there is no alternative future use, and combined with the assets, liabilities and results of operations of Ocuphire after the consummation of the merger.

The unaudited pro forma condensed combined financial information is based on the assumptions and adjustments that are described in the accompanying notes. The accounting for the transaction as an asset acquisition is dependent upon the valuation of the IPR&D and the final calculation of net working capital for Rexahn. Accordingly, the pro forma adjustments are preliminary, subject to further revision as additional information becomes available and additional analyses are performed and have been made solely for the purpose of providing unaudited pro forma condensed combined financial information. Differences between these preliminary estimates and the final accounting, to be completed after the Closing, will occur and these differences could have a material impact on the accompanying unaudited pro forma condensed combined financial information and the combined company’s future results of operations and financial position. In addition, differences between the preliminary and final amounts will likely occur as a result of the amount of cash used for Rexahn’s operations and other changes in Rexahn’s assets and liabilities between September 30, 2020 and the actual closing.

The unaudited pro forma condensed combined financial information does not give effect to the potential impact of current financial conditions, regulatory matters, operating efficiencies or other savings or expenses that may be associated with the integration of the two companies. The unaudited pro forma condensed combined financial information is preliminary and has been prepared for illustrative purposes only and is not necessarily indicative of the financial position or results of operations in future periods or the results that actually would have been realized had Rexahn and Ocuphire been a combined company during the specified periods. The actual results reported in periods following the merger may differ significantly from those reflected in the unaudited pro forma condensed combined financial information presented herein for a number of reasons, including, but not limited to, differences in the assumptions used to prepare this pro forma financial information.

The unaudited pro forma condensed combined financial information, including the notes thereto, should be read in conjunction with the separate historical financial statements of Rexahn and Ocuphire, and their respective management’s discussion and analysis of financial condition and results of operations included in Rexahn’s proxy statement/prospectus/information statement filed on October 2, 2020 with the Securities and Exchange Commission (“SEC”). Rexahn’s audited statement of operations for the year ended December 31, 2019 is derived from Rexahn’s Annual Report on Form 10-K for the year ended December 31, 2019. Rexahn’s unaudited financial statements for the nine months ended September 30, 2020 are derived from Rexahn’s Quarterly Report on Form 10-Q for the nine months ended September 30, 2020.

Accounting rules require evaluation of certain assumptions, estimates, or determination of financial statement classifications which are completed during the measurement period as defined in current accounting standards. The accounting policies of Rexahn may materially vary from those of Ocuphire. During preparation of the unaudited pro forma condensed combined financial information, management has performed a preliminary analysis and is not aware of any material differences, and accordingly, this unaudited pro forma condensed combined financial information assumes no material differences in accounting policies. Following the acquisition, management will conduct a final review of Rexahn’s accounting policies in order to determine if differences in accounting policies require adjustment or reclassification of Rexahn’s results of operations or reclassification of assets or liabilities to conform to Ocuphire’s accounting policies and classifications. As a result of this review, management may identify differences that, when conformed, could have a material impact on these unaudited pro forma condensed combined financial statements.

NOTES TO THE UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

1. Description of Transaction

On June 17, 2020, Rexahn entered into an Agreement and Plan of Merger and Reorganization, as amended on June 29, 2020 (the “Merger Agreement”) with Ocuphire pursuant to which Rexahn’s wholly owned subsidiary, Merger Sub, agreed to merge with and into Ocuphire, with Ocuphire surviving as a wholly owned subsidiary of Rexahn, in an all-stock transaction. Subject to the terms and conditions of the Merger Agreement, on November 5, 2020, (a) each share of Ocuphire common stock outstanding immediately prior to the Effective Time was converted into the right to receive shares of Rexahn common stock equal to the Exchange Ratio described below; and (b) each outstanding Ocuphire Option that was not previously been exercised prior to the Effective Time was assumed by Rexahn.

The calculation of the Exchange Ratio under the Merger Agreement and post-closing ownership of Rexahn Stockholders was subject to adjustment based on an assumed value of Rexahn at Closing, including Rexahn’s Parent Cash Amount. To the extent the Parent Cash Amount falls below $3.2 million or exceeds $6.0 million, Rexahn’s assumed value would be reduced or increased by $150,000 for every $100,000 below or above the thresholds referenced. For pro forma purposes, the Parent Cash Amount is assumed to be $2.3 million as of September 30, 2020 based on Rexahn’s then current estimates of such amount on the Anticipated Closing Date. In the event of a Parent Cash Amount of $2.3 million, Rexahn Stockholders would own approximately 13.5% of the combined company’s common stock, and the Ocuphire Securityholders would own, or hold rights to acquire, approximately 86.5% of the combined company’s common stock, in each case calculated on a fully-diluted basis. Under the terms of the Merger Agreement, Rexahn Stockholders’ ownership percentage in the combined company was subject to a floor of approximately 9.1% regardless of Rexahn’s actual Parent Cash Amount at Closing, which assumed Ocuphire waives the minimum requirement at Closing.

5

Consummation of the merger was subject to certain closing conditions, including, among other things, approval by the Rexahn Stockholders and Ocuphire Stockholders, consummation of the Pre-Merger Financing, the continued listing of the Rexahn common stock on the Nasdaq Capital Market, the conversion of all Ocuphire convertible notes into Ocuphire common stock and satisfaction by Rexahn of a Parent Cash Amount of at least $0 as of the Anticipated Closing Date.

In June 2020, certain accredited investors, including certain Ocuphire directors and executives, entered into the Securities Purchase Agreement with Ocuphire and Rexahn, pursuant to which Ocuphire will receive gross proceeds of $21.15 million, which will close immediately prior to the Closing, assuming the satisfaction or waiver of customary closing conditions. Investors in the Pre-Merger Financing will receive certain initial shares of the Company (the “Initial Shares”), which will convert into Company common stock upon Closing. Additionally, following the Closing, the Company is to issue certain warrants (the “Investor Warrants”) to these investors, as well as any additional shares (“Converted Additional Shares”) owed to such Investors based on the final purchase price. The accompanying unaudited pro forma condensed combined financial statements reflect the receipt by Ocuphire of the total $21.15 million in gross proceeds, as well as the issuance of the Initial Shares of Company common stock to investors prior to the Closing, but do not account for any Converted Additional Shares of Company common stock that may be issued or the Investor Warrants issuable to the Investors after the Closing because the amount and timing of these issuances was not yet known as of September 30, 2020.

At the Effective Time, Rexahn was also to enter into the CVR Agreement. Pursuant to the Merger Agreement and the CVR Agreement, for each share of Rexahn common stock held after giving effect to the Rexahn Reverse Stock Split, Rexahn Stockholders of record as of immediately prior to the Effective Time were to receive one CVR. Each CVR entitles such holders to receive, for each calendar quarter during the 15-year period after the Closing, an amount equal to (i) 90% of all payments received by Rexahn pursuant to its licensing agreements with BioSense Global LLC and Zhejiang HaiChang Biotechnology Co., Ltd.; and (ii) 75% of the proceeds from any future monetization of Rexahn’s intellectual property that is entered into during the 10-year period after the Closing, in each case, less certain permitted deductions. The CVRs are not transferable, except in certain limited circumstances, will not be certificated or evidenced by any instrument, will not accrue interest and will not be registered with the SEC or listed for trading on any exchange. The CVR Agreement will be effective prior to the Closing and will continue in effect until the later of the end of the CVR Term and the payment of all amounts payable thereunder.

2. Estimated Purchase Price

The accompanying unaudited pro forma condensed combined financial statements reflect an estimated reverse asset acquisition price of approximately $11.3 million. Given that the estimated purchase price is variable depending upon the price of Rexahn common stock acquired upon consummation of the merger, management performed a sensitivity analysis over the change in purchase consideration based on +/– 10% volatility in Rexahn common stock price. An increase or decrease in the Rexahn common stock price by 10% would increase or decrease the purchase consideration by approximately $0.9 million with an offsetting adjustment to IPR&D. Under certain circumstances further described in the Merger Agreement, the ownership percentages are subject to adjustment to the extent that Rexahn’s Parent Cash Amount as of the Anticipated Closing Date is below $3.2 million or above $6.0 million.

6

The total estimated purchase price and allocated purchase price is summarized as follows:

Estimated number of shares of the combined company to be owned by Rexahn’s stockholders(i)		1,120,800
Multiplied by the fair value per share of Rexahn’s common stock(ii)	$	8.32
​Total		​9,325,056
Rexahn warrants assumed in merger		191,332
Rexahn stock options assumed in merger		27
Estimated transaction costs		1,780,907
Total estimated purchase price	$	11,297,322

For purposes of this pro forma analysis, the above estimated purchase price has been allocated based on a preliminary estimate of the fair value of assets and liabilities to be acquired.

Net assets as of September 30, 2020	$	6,343,058
In process research and development(iii)		4,954,264
Total estimated purchase price	$	11,297,322

(i) The final purchase price is be determined based in part on the number of shares of Rexahn common stock and the value of Rexahn Warrants and Rexahn Options outstanding immediately prior to the merger. For purposes of this unaudited pro forma condensed combined financial information, the estimated number of shares represents 1,120,800 shares of Rexahn common stock outstanding as adjusted for a 1-for-4 Rexahn Reverse Stock Split that is to be effected prior to consummation of the merger.

(ii) The estimated purchase price was based on the Rexahn September 30, 2020 closing price as reported on the Nasdaq Capital Market as adjusted for a 1-for-4 Rexahn Reverse Stock Split that was effected prior to consummation of the merger. The final purchase price arising from the actual transaction costs, the number of shares and fair value of Rexahn common stock as well as the fair value of Rexahn Warrants and Rexahn Options outstanding immediately prior to the Closing could result in a total purchase price different from that assumed in this unaudited pro forma condensed combined financial information, and that difference may be material. Therefore, the estimated consideration expected to be transferred reflected in this unaudited pro forma condensed combined financial information does not purport to represent what the actual consideration transferred will be upon completion of the merger. The actual purchase price will fluctuate until the Closing, and the final valuation of the purchase consideration could differ significantly from the current estimate.

(iii) IPR&D represents the research and development projects of Rexahn which were in-process, but not yet completed, and which Ocuphire plans to advance. This includes the development of RX-3117, RX-0301 and RX-0047. Current accounting standards require that the fair value of IPR&D projects acquired in an asset acquisition with no alternative future use be allocated a portion of the consideration transferred and charged to expense at the acquisition date. The acquired assets did not have outputs or employees. The actual purchase price allocated to IPR&D will fluctuate until the Closing, and the final valuation of the IPR&D consideration could differ significantly from the current estimate.

Contingent consideration with respect to the CVRs has not been recorded in the accompanying unaudited pro forma condensed combined financial statements as the CVRs are not subject to derivative liability treatment given a scope exception to such treatment under GAAP. The Company will record a liability for the CVRs once payment under the CVR Agreement is determined to be both  probable and estimable, which is not expected to occur until the contingencies under the CVR Agreement are resolved. Upon recognition, the amounts pursuant to the CVR Agreement will be included in the cost of IPR&D and expensed at such time.   

3. Pro Forma Adjustments

Adjustments included in the column under the heading “Pro Forma Adjustments” are primarily based on information contained within the Merger Agreement. Further analysis will be performed after the completion of the merger to confirm the necessity of these estimates.

Given Ocuphire’s history of net losses and valuation allowance, management assumed a statutory tax rate of 0%. Therefore the pro forma adjustments to the statement of operations resulted in no additional income tax adjustment to the pro forma financials.

7

The pro forma adjustments relate to the following:

A. To reflect the conversion of the Ocuphire convertible notes (principal and accrued interest) and the application of premium conversion derivatives into shares of Rexahn common stock prior to the merger, in accordance with the terms of the Note Conversion Agreement.

B. To record the remaining debt discount amortization expense on the Ocuphire convertible notes. The accelerated debt discount amortization expense is not reflected in the pro forma statements of operations because it does not have a continuing impact. Adjustments to convertible notes are as follows:

	September 30, 2020
Conversion of Ocuphire’s convertible notes principal and interest (A)	$	(9,299,876	)
Debt discount amortization expense on Ocuphire’s convertible notes payable (B)		—
Total	$	(9,299,876	)

C. To reflect accounting treatment of Ocuphire convertible notes conversion into common stock as a loss on extinguishment in connection with the merger. The loss on extinguishment is not reflected in the pro forma statements of operations because it does not have a continuing impact.

D. To record the estimated fully vested fair value of Rexahn Options assumed in connection with the merger.

E. To reflect the estimated fair value of Rexahn Warrants assumed in connection with the merger (including both liability and equity classified portions), and assuming holders of Rexahn Warrants do not exercise their right to exchange their Rexahn Warrants for cash in an amount equal to the Black-Scholes value of such warrants calculated as set forth therein and in accordance with the terms of such Rexahn Warrants.

F. To record Rexahn’s estimated transaction costs, such as severance and benefits, advisory fees and transactional fees, that were not incurred as of September 30, 2020. The Rexahn transaction costs are not reflected in the pro forma statements of operations because they do not have a continuing impact.

G. To record Ocuphire’s estimated transaction costs, such as legal, accounting, advisory and other transactional fees, that were not incurred as of September 30, 2020. The Ocuphire transaction costs are not reflected in the pro forma statements of operations because they do not have a continuing impact.

Adjustments to accrued expenses are as follows:

	September 30, 2020
Rexahn’s estimated transaction costs (F)	$	3,965,228
Ocuphire’s estimated transaction costs (G)		313,257
Total	$	4,278,485

8

H. To reclassify proceeds receivable from convertible notes to other current assets as a result of the note conversions into Ocuphire common stock in connection with the merger.

I. To reflect the Pre-Merger Financing upon Closing for a total of $21.15 million in gross proceeds, less issuance costs of approximately $1.6 million. The accounting treatment under Accounting Standards Codification (ASC) 480 – Distinguishing Liabilities from Equity and ASC 815 – Derivatives and Hedging is in process related to the Pre-Merger Financing, including the accounting classification of the Investor Warrants and Converted Additional Shares. For purposes of these pro formas, the Pre-Merger Financing has been classified as equity. Upon close of the Pre-Merger Financing, certain cash settlement provisions, registration requirements, or other adjustments not afforded to other stockholders, may result in the Investor Warrants and Converted Additional Shares being accounted for as a liability on the balance sheet until all of the settlement contingencies are resolved for those instruments.  The liability accounting impact would result in some of the Pre-Merger Financing, currently classified in the pro formas as equity, to be reclassified as a liability on the condensed combined balance sheet.  In addition, any liability recognized for the Pre-Merger Financing would be subject to remeasurement at fair value as of each reporting period with offsetting impacts of the fair value changes to the statement of operations.

J. To adjust Rexahn’s historical financial statements to give pro forma effect to events in connection with the merger that include: 1) the elimination of Rexahn’s historical common stock, paid-in-capital and accumulated deficit balances; 2) the elimination of Rexahn’s deferred revenue liability given the non-assumption of the obligation post-merger; and 3) the write-down of Rexahn’s facility lease and property and equipment reported values to reflect their fair value based on their anticipated non-usage post-merger.

K. To reflect the following impacts to the historical financial statements to give pro forma effect to events in connection with the merger that include: 1) the expensing of Rexahn’s IPR&D; 2) the capitalization of the fair value of the estimated number of common shares, warrants and stock options of the combined company to be owned by Rexahn Stockholders as adjusted for the 1-for-4 Rexahn Reverse Stock Split; 3) the impact of transaction costs impacting the estimated purchase price of the merger; and 4) to reflect the impact of the Exchange Ratio to the outstanding common shares of the combined company. The IPR&D expense is not reflected in the pro forma statements of operations because it does not have a continuing impact.

L. To reflect milestone payments due to Apexian upon Closing.

9

M. Adjustments to additional-paid-in-capital are as follows:

	September 30, 2020
Conversion of Ocuphire’s convertible notes and accrued interest (A)		$	9,299,784

Total	$	(93	)

P. The pro forma combined basic and diluted net loss per share calculations have been adjusted to reflect the pro forma net loss for the nine months ended September 30, 2020 and for the year ended December 31, 2019. In addition, the number of shares used in calculating the pro forma combined basic and diluted net loss per share has been adjusted to reflect the estimated total number of shares of common stock of the combined company that would be outstanding on a weighted-average basis as of the closing of the merger. The following table is a reconciliation of the Company’s historical basic and diluted loss per share to its pro forma basic and diluted loss per share for the nine months ended September 30, 2020 and for the year ended December 31, 2019.

The pro forma adjustments to the Ocuphire convertible notes and accrued interest as set forth in the table above assume a conversion date as of the beginning of the period presented.

The application of the estimated exchange ratio of 1.0579 to Ocuphire’s weighted-average common shares outstanding as set forth in the table above is based on the pro forma post-closing capitalization as of September 30, 2020 and assumes (i) the Ocuphire convertible notes and accrued interest are converted as of the beginning of the period presented, and (ii) Rexahn’s Parent Cash Amount is $2.3 million on the Anticipated Closing Date.

Accordingly, pro forma combined basic and diluted net loss per share reflects the pro forma combined net loss for the period presented over the pro forma combined weighted-average common shares outstanding for the period presented as reflected on the unaudited pro forma condensed combined statement of operations for such period. Given the expected pro forma net losses of the combined company, the Investor Warrants, Converted Additional Shares, stock options and other warrants were not considered given their antidilutive effect.
