Code of Ethics

We have adopted a code of conduct and ethics (the “Code of Ethics”) that applies to our principal executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions, in accordance with applicable federal securities laws and as required by The Nasdaq Stock Market (“Nasdaq”). The Code of Ethics is available on our corporate website at www.rexahn.com.

Audit Committee

The Board of Directors has a separately designated Audit Committee with a written charter that provides that the committee, among other things:

 

 

 

 

 

 

Mr. Rodgers, Dr. Cheong, and Mr. Beever serve as members of the Audit Committee. Mr. Rodgers serves as Chair of the Audit Committee. The Board of Directors has determined that both Mr. Rodgers and Dr. Cheong are audit committee financial experts within the meaning of applicable Securities and Exchange Commission (“SEC”) regulations. Each of the current members meets the criteria for independence required by Nasdaq and Rule 10A-3 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

 

Item 11.

Executive Compensation.

The following table sets forth the compensation for our named executive officers for services rendered in all capacities to the Company for the years ended December 31, 2019 and 2018. Our named executive officers include our current principal executive officer and financial officer and the two other former executive officers who served during 2019. The compensation described in this table does not include medical or other benefits that are available generally to all of our salaried employees.

 

Narrative Disclosure to Summary Compensation Table

 

Base Salary. The base salary payable to each named executive officer is intended to provide a fixed component of compensation reflecting the executive’s skill set, experience, roles and responsibilities.

 

Short-term Incentive Program. Our 2019 STI program was intended to provide a cash incentive to our named executive officers for achieving company-wide goals approved at the beginning of the year by the Compensation Committee. We believe that having an annual STI program provided an important and customary retention tool and motivated our executives to achieve the specific goals that were a part of the program. The Compensation Committee established a set bonus target expressed as a percentage of salary for each named executive officer and established goals for the STI program. After the conclusion of the year, the Compensation Committee determined at what level the goals were achieved.

 

Long-term Incentive Program. Our use of equity awards is intended to align our named executive officers’ interests with the interest of our shareholders by providing an incentive to our named executive officers to increase long-term shareholder value. Furthermore, we believe that in the biopharmaceutical industry, equity awards are a primary motivator to retain executives. We determine the size, mix and frequency of the awards based on numerous factors, including the executive’s skills and experience, the executive’s responsibilities, performance in the prior year and our approach to setting compensation. For 2019, we used stock options for equity awards. All of the stock options issued to the named executive officers vest over a four year-period, with the first installment vesting on the first anniversary of the award.

 

Employment Agreements. At the time each of our named executive officers joined the Company, we entered into employment agreements with them. Mr. Swirsky’s agreement was subsequently amended in 2018 to reflect his promotion to Chief Executive Officer, as described more fully below under “Employment Agreement with Mr. Swirsky.” These agreements were designed to be a part of a competitive compensation package for a publicly traded company and to keep our named executive officers focused on our business goals and objectives. In March 2019, Dr. Benaim informed us of his resignation from the Company. In August 2019, Dr. Nolan informed us of her resignation from the Company.

 

Payments on Termination. Pursuant to his employment agreement, Mr. Swirsky is entitled to specified benefits in the event of the termination of his employment under specified circumstances, including termination following a change of control of the Company. The terms of this arrangement is more fully described below under “Mr. Swirsky’s Employment Agreement.” We believe these protections are appropriate for the senior executives of a biopharmaceutical company such as the Company, including because of the level of acquisition activity in this industry. We believe that providing benefits in the event of a change of control of the Company allows our named executive officers to focus their attention on building our business rather than on the personal implications of a transaction. Under the terms of their former employment agreements, each of Dr. Benaim and Dr. Nolan were entitled upon their resignations only to the base salary to which they were entitled for the period ending on the resignation date and the base salary for accrued but unused vacation as of the resignation date.

 

Employment Agreement with Mr. Swirsky

Effective January 2, 2018, we entered into an employment agreement with Mr. Swirsky to serve as our President and Chief Financial Officer, which was subsequently amended on November 14, 2018 upon Mr. Swirsky’s promotion to Chief Executive Officer. Pursuant to the amended employment agreement, we agreed to pay Mr. Swirsky a base salary of $425,000 with the option of a discretionary annual cash bonus of up to 40% of his base salary for 2018 and up to 50% of his base salary for subsequent years, as determined by performance against objectives and milestones set by the Board of Directors. Mr. Swirsky’s employment agreement provided for an initial grant of 20,833 options to purchase shares of our common stock, and the amended employment agreement entered into in connection with his promotion to Chief Executive Officer provided for an additional grant of 41,666 options to purchase shares of our common stock and that the Board of Directors may award him additional options each year. In the event Mr. Swirsky’s employment is terminated by reason of disability or for “Cause,” as defined in the employment agreement, we will pay Mr. Swirsky his base salary owed up to the termination date, including payment for any unused vacation days, and any earned but unpaid annual bonus for a year prior to the year in which the termination occurs. If we terminate Mr. Swirsky’s employment without Cause or Mr. Swirsky terminates his employment with “Good Reason,” as defined below, then Mr. Swirsky’s stock options will be subject to accelerated vesting to the extent to which they would have vested within the 12 months following termination and we will pay Mr. Swirsky his base salary owed up to the termination date, including payment for any unused vacation days, any earned but unpaid annual bonus for a year prior to the year which the termination occurs, a lump sum equal to his then-current annual base salary, an amount equal to the pro-rata portion of the bonus that he otherwise would have been entitled to, and COBRA premiums for 12 months if he makes a timely election and is eligible for coverage. In the event we terminate Mr. Swirsky’s employment without Cause or Mr. Swirsky terminates his employment with Good Reason within the two-year period following a “Change of Control,” as defined in the 2013 Stock Option Plan (the “2013 Plan”), we will pay Mr. Swirsky his base salary owed up to the termination date, including payment for any unused vacation days, any earned but unpaid annual bonus for a year prior in which the termination occurs, a lump sum equal to 150% of his current annual base salary and 150% of his target bonus, an amount equal to the bonus he would have otherwise been entitled to, assuming Mr. Swirsky would have received a bonus for the fiscal year equal to his target bonus if he had stayed employed with the company for the entire year, and COBRA premiums for 18 months if he makes a timely election. Mr. Swirsky’s equity awards would also vest and become exercisable in connection with the Change of Control. A resignation by Mr. Swirsky is deemed a resignation for “Good Reason” if he provides written notice to the Company of the specific circumstances alleged to constitute Good Reason within 90 days after any one or more of the following events and such Good Reason is not cured within 30 days of our receipt of such notice:

 

 

 

 

 

The employment agreement also contains a provision prohibiting Mr. Swirsky from soliciting our executives, employees, customers or clients for a period of 12 months following his termination.

Outstanding Equity Awards at Fiscal Year-End

 

The following table shows certain information regarding outstanding equity awards for the named executive officers as of December 31, 2019.

 

 

 

Director Compensation

The non-employee director cash compensation structure for 2019 was as follows:

*	Paid semi-annually.

As part of the director compensation structure, each incumbent non-employee director currently also receives an annual equity grant equal to 0.088% of the outstanding shares of the Company at the time of grant. The Company also has an informal policy to grant each incoming director an equity award equal to twice the annual grant.

The table below sets forth information concerning the compensation of our directors for the year ended December 31, 2019, except for Mr. Swirsky, whose compensation is disclosed above.

Item 13.

Certain Relationships and Related Transactions, and Director Independence.

Certain Relationships and Related Person Transactions

The Audit Committee charter requires that the Audit Committee review and approve all proposed transactions between the Company and any director, officer or other employee of the Company, and any holder of 5% or more of our voting capital stock, in order to ensure that any such transaction is on an arm’s length basis and in accordance with all applicable laws and regulations and the requirements of any exchange on which our securities may be listed from time to time. Based on our review of our transactions, there have been no transactions or proposed transactions considered to be related person transactions since January 1, 2018.

 

Director Independence

 

Our common stock is currently listed on the Nasdaq Capital Market. Our Corporate Governance Guidelines define an “independent” director for the purposes of the Board of Directors and its committees in accordance with the applicable provisions of the Exchange Act, the rules promulgated thereunder, and the applicable rules of Nasdaq. We currently have a total of seven directors, six of whom are independent. Our independent directors are Messrs. Brandt, Beever, and Rodgers and Drs. Cheong, Price and Sullivan. In making the independence determination with respect to Dr. Price, the Board considered that his employer provides pharmacovigilance services to the Company.
