EXPLANATORY NOTES







Amendment No.1



This Amendment No. 1 to Form 10-K (this “Amendment No. 1”) amends the Annual Report on Form 10-K of Diffusion Pharmaceuticals Inc., a Delaware corporation (the “Company”) for the year ended December 31, 2016, filed with the Securities and Exchange Commission (the “SEC”) on March 31, 2017 (the “Original Filing”). This Amendment No. 1 is being filed to provide the information required by Items 10 through 14 of Part III. This information was previously omitted from the Original Filing in reliance on General Instruction G(3) to Form 10-K, which permits the information in the above-referenced items to be incorporated in the Form 10-K by reference from a definitive proxy statement involving the election of directors if such statement is filed no later than 120 days after our fiscal year end. We are filing this Amendment No.1 to include Part III information in our Form 10-K because we will not file our definitive proxy statement containing this information before that date.



In addition, pursuant to the rules and regulations promulgated by the SEC, we have also included as exhibits currently dated certifications of our principal executive officer and principal financial officer as required under Section 302 of the Sarbanes-Oxley Act of 2002.



Except as described above, no other changes have been made to the Original Filing. Except as otherwise explicitly stated herein, this Amendment No. 1 continues to speak as of the date of the Original Filing, and we have not updated the disclosures contained therein to reflect any events that occurred subsequent to the date of the Original Filing. The filing of this Amendment No. 1 is not a representation that any statements contained in items of our Original Filing other than Items 10 through 14 of Part III, and Part IV are true or complete as of any date subsequent to the Original Filing. This Amendment No. 1 should be read in conjunction with our other filings made with the SEC subsequent to the date of the Original Filing, including any amendments to those filings, as well as our Current Reports filed on Form 8-K subsequent to the date of the Original Filing.



Merger with Diffusion Pharmaceuticals LLC



As previously disclosed, on January 8, 2016, the Company (f/k/a RestorGenex Corporation) completed the merger (the “Merger”) of its wholly owned subsidiary, Arco Merger Sub, LLC (“Merger Sub”), with and into Diffusion Pharmaceuticals LLC, a Virginia limited liability company (“Diffusion LLC”), in accordance with the terms of the Agreement and Plan of Merger, dated as of December 15, 2015, among the Company, Merger Sub and Diffusion LLC (the “Merger Agreement”). As a result of the Merger, Diffusion LLC, the surviving company in the Merger, became a wholly owned subsidiary of the Company and, following the Merger, the Company changed its corporate name from RestorGenex Corporation (“RestorGenex”) to Diffusion Pharmaceuticals Inc.



For accounting purposes, the Merger is treated as a “reverse acquisition” under generally acceptable accounting practices in the United States (“U.S. GAAP”) and Diffusion LLC is considered the accounting acquirer. Accordingly, Diffusion LLC’s historical results of operations will replace the Company’s historical results of operations for all periods prior to the Merger.



Unless the context otherwise requires, references to “Diffusion,” the “Company,” “we,” “our” or “us” in this report refer to Diffusion Pharmaceuticals Inc. and its subsidiaries, following the completion of the Merger and Diffusion Pharmaceuticals LLC prior to the completion of the Merger, references to “RestorGenex” refer to the Company prior to the completion of the Merger and references to “Diffusion LLC” refer to Diffusion Pharmaceuticals LLC.



Except as otherwise noted, references to “common stock” in this report refer to common stock, par value $0.001 per share, of the Company.



This report contains the following trademarks, trade names and service marks of ours: RestorGenex and Diffusion. All other trade names, trademarks and service marks appearing in this Amendment No. 1 are the property of their respective owners. We have assumed that the reader understands that all such terms are source-indicating. Accordingly, such terms appear without the trade name, trademark or service mark notice for convenience only and should not be construed as being used in a descriptive or generic sense.

The paragraphs below provide information about each current director, including all positions he holds, his principal occupation and business experience for the past five years, and the names of other publicly held companies of which he currently serves as a director or served as a director during the past five years. We believe that all of our director nominees display personal and professional integrity; satisfactory levels of education and/or business experience; broad-based business acumen; an appropriate level of understanding of our business and its industry and other industries relevant to our business; the ability and willingness to devote adequate time to the work of the Board and its committees; a fit of skills and personality with those of our other directors that helps build a board of directors that is effective, collegial and responsive to the needs of our company; strategic thinking and a willingness to share ideas; a diversity of experiences, expertise and background; and the ability to represent the interests of all of our stockholders. The information presented below regarding each director also sets forth specific experience, qualifications, attributes and skills that led the Board to the conclusion that he or she should serve as a director in light of our business and structure.



David G. Kalergis – Mr. Kalergis has served as our Chairman of the Board and Chief Executive Officer since the completion of the Merger. Mr. Kalergis, along with Dr. Gainer, is the Company’s co-founder and has served as a director of Diffusion LLC since its inception in 2001 and as its Chief Executive Officer since 2004.

Alan Levin – Mr. Levin has served as a director since the completion of the Merger in January 2016 and as a director of Diffusion LLC since June 2015. He previously served as Executive Vice President and Chief Financial Officer of Endo Health Solutions Inc. (“Endo”), a global specialty healthcare company, from June 2009 until his retirement in September 2013.

He is also a member of the Advisory Board of Auven Therapeutics, a private equity fund; and the Critical Path Institute, a nonprofit collaboration between the Food and Drug Administration and pharmaceutical industry participants focused on streamlining and accelerating the development and regulatory pathways for innovative medicines.



The Board believes that the combination of Mr. Levin’s perspective and experience as a director of Diffusion; his experience in financial reporting, treasury and corporate finance (including his prior positions as chief financial officer of Endo and Pfizer, Inc.); and his executive-level experience in the pharmaceutical industry all provide him with the qualifications and skills to serve as a director.

Director Independence



The Board has determined that four of our six current directors — Isaac Blech, Robert Adams, Mark T. Giles and Alan Levin — are “independent directors” under the Listing Rules of The NASDAQ Stock Market. The Listing Rules of The NASDAQ Stock Market provide a non-exclusive list of persons who are not considered independent. For example, under these rules, a director who is, or during the past three years was, employed by Diffusion or by any parent or subsidiary of Diffusion, other than prior employment as an interim chairman or Chief Executive Officer, would not be considered independent. No director qualifies as independent unless the Board affirmatively determines that the director does not have a material relationship with the listed company that would interfere with the exercise of independent judgment. In making an affirmative determination that a director is an “independent director,” the Board reviewed and discussed information provided by these individuals and by us with regard to each of their business and personal activities as they may relate to us and our management. Mr. Kalergis and Dr. Gainer are not considered independent due to their executive officer positions with the Company.








Board Leadership Structure



The Board believes that our stockholders are best served if the Board retains the flexibility to adapt its leadership structure to applicable facts and circumstances, which necessarily change over time. Accordingly, under our Corporate Governance Guidelines, the office of Chairman of the Board and Chief Executive Officer may or may not be held by one person. The Board believes it is best not to have a fixed policy on this issue and that it should be free to make this determination based on what it believes is best under the circumstances.



Currently, David G. Kalergis serves as both the Chairman of the Board and as our Chief Executive Officer. The Board believes that it is currently in the best interests of the Company's stockholders to combine these offices as it promotes information flow between management and the Board, effective decision making and an alignment of corporate strategy. However, the Board strongly endorses the concept of an independent director being in a position of leadership for the rest of the outside directors.  Under our Corporate Governance Guidelines, if at any time the Chief Executive Officer and Chairman of the Board positions are held by the same person, the Board, upon recommendation of the Nominating and Corporate Governance Committee, will elect an independent director as a lead independent director. Mark T. Giles currently serves as our lead independent director. In addition, Isaac Blech, also an independent director, serves as the Vice Chairman of the Board.



Executive Sessions



At each regular meeting of the Board, our independent directors meet in executive session with no company management present during a portion of the meeting. Mr. Giles as our lead independent director presides over these executive sessions and serves as a liaison between the independent directors and our Chief Executive Officer.



Board Meetings and Attendance



The Board held 11 meetings during 2016. Each of the directors on the Board during 2016 attended 75 percent or more of the aggregate meetings of the Board and all committees on which he served for the period during 2016 in which he served as a director. In addition, the Company's directors are expected to attend annual meetings of stockholders, and all of the Company's directors who were serving as directors at the time of the 2016 annual meeting attended the 2016 annual meeting of stockholders or participated telephonically.



Board Committees



The Board has three standing committees: Audit Committee, Compensation Committee and Nominating and Corporate Governance Committee. Each of these committees has the composition and responsibilities described below. The Board from time to time may establish other committees to facilitate the management of our company and may change the composition and the responsibilities of our existing committees. Each of our three standing committees has a charter which can be found on the Investor Relations—Corporate Governance section of our corporate website at www.diffusionpharma.com. Messrs. Adams, Giles and Levin currently serve as the members of all three of our standing committees. Mr. Adams is the chairman of the Compensation Committee, Mr. Giles is the chairman of the Nominating and Corporate Governance Committee and Mr. Levin is the chairman of the Audit Committee.

The Audit Committee has the authority to engage the services of outside experts and advisors as it deems necessary or appropriate to carry out its duties and responsibilities.



Composition and Audit Committee Financial Expert. The current members of the Audit Committee are Messrs. Adams, Giles and Levin.  Mr. Levin is the chair of the Audit Committee.



Each current member of the Audit Committee qualifies as “independent” for purposes of membership on audit committees under the Listing Rules of The NASDAQ Stock Market and the rules and regulations of the SEC and is “financially literate” under the Listing Rules of The NASDAQ Stock Market. In addition, the Board has determined that Mr. Levin qualifies as an “audit committee financial expert” as defined by the rules and regulations of the SEC and meets the qualifications of “financial sophistication” under the Listing Rules of The NASDAQ Stock Market as a result of his experience in senior financial positions. Stockholders should understand that these designations related to the Audit Committee members’ experience and understanding with respect to certain accounting and auditing matters are disclosure requirements of the SEC and The NASDAQ Stock Market and do not impose upon any of them any duties, obligations or liabilities that are greater than those generally imposed on a member of the Audit Committee or of the Board.



Meetings. The Audit Committee met 8 times during 2016.



Processes and Procedures for Complaints. The Audit Committee has established procedures for the receipt, retention and treatment of complaints received by us regarding accounting, internal accounting controls, or auditing matters, and the submission by our employees, on a confidential and anonymous basis, of concerns regarding questionable accounting or auditing matters. Our personnel with such concerns are encouraged to discuss their concerns with their supervisor first, who in turn will be responsible for informing our Chief Executive Officer of any concerns raised. If an employee prefers not to discuss a particular matter with his or her own supervisor, the employee may instead discuss such matter with our Chief Executive Officer. If an individual prefers not to discuss a matter with the Chief Executive Officer or if the Chief Executive Officer is unavailable and the matter is urgent, the individual is encouraged to contact the Chair of the Audit Committee, Alan Levin.



Compensation Committee



Responsibilities. The primary responsibilities of the Compensation Committee include:



| | ● | determining the annual salaries, incentive compensation, long-term incentive compensation, special or supplemental benefits or perquisites and any and all other compensation applicable to our Chief Executive Officer and other executive officers;
| | - | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------








| | ● | determining any revisions to corporate goals and objectives with respect to compensation for our Chief Executive Officer and other executive officers and establishing and leading a process for the full Board to evaluate the performance of our Chief Executive Officer and other executive officers in light of those goals and objectives;
| | - | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | ● | administering our equity-based compensation plans, including determining specific grants of options and other awards for executive officers and other employees under our equity-based compensation plans;
| | - | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | ● | reviewing and discussing with our Chief Executive Officer and reporting periodically to the Board plans for executive officer development and corporate succession plans for the Chief Executive Officer and other key executive officers and employees; and
| | - | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | ● | establishing and leading a process for determination of the compensation applicable to the non-employee directors on the Board.
| | - | -------------------------------------------------------------------------------------------------------------------------------



The Compensation Committee has the authority to engage the services of outside experts and advisors as it deems necessary or appropriate to carry out its duties and responsibilities.



Composition. The current members of the Compensation Committee are Messrs. Adams, Giles and Levin.  Mr. Adams is the chair of the Compensation Committee. Each of the three current members of the Compensation Committee is an “independent director” under the Listing Rules of The NASDAQ Stock Market and a “non-employee director” within the meaning of Rule 16b-3 under the Exchange Act.



Meetings. The Compensation Committee met 16 times during 2016.



Processes and Procedures for Consideration and Determination of Executive Compensation. As mentioned above, the Compensation Committee has authority to determine all compensation applicable to our executive officers. In setting executive compensation for our executive officers, the Compensation Committee considers, among other things, the following primary factors: each executive’s position within the company and the level of responsibility; the ability of the executive to affect key business initiatives; the executive’s individual experience and qualifications; compensation paid to executives of comparable positions by companies similar to our company; company and individual performance; the executive’s current and historical compensation levels; recommendations of our Chief Executive Officer and input from the Compensation Committee’s independent consulting firm, Radford.



In making decisions regarding the form and amount of compensation to be paid to our executive officers (other than our Chief Executive Officer), the Compensation Committee considers and gives weight to the recommendations of our Chief Executive Officer recognizing that due to his reporting and otherwise close relationship with each executive, the Chief Executive Officer often is in a better position than the Compensation Committee to evaluate the performance of each executive (other than himself). In making decisions regarding the form and amount of compensation to be paid to our Chief Executive Officer, the Compensation Committee considers the recommendation of the Chief Executive Officer with respect to his own compensation and the Compensation Committee’s own assessment of the Chief Executive Officer’s annual performance and input from other Board members. The Compensation Committee meets in executive session regularly and makes all executive compensation decisions without the presence of the Chief Executive Officer or any executive or employee of our company.



The Compensation Committee has retained the services of Radford to provide advice with respect to executive compensation. Radford was engaged directly by the Compensation Committee in 2016 and did not advise our management and only worked with management with the express permission of the Compensation Committee. Radford did not provide any services to our company in 2016 other than those for which it was retained by the Compensation Committee. Radford’s engagement by the Compensation Committee includes reviewing and advising on all significant aspects of executive compensation. This includes base salaries, short-term cash incentives and long-term equity incentives for our executives, and cash compensation and long-term equity incentives for our non-employee directors. In so doing, at the request of the Compensation Committee, Radford recommended a peer group of companies, collected relevant market data from these companies to allow the Compensation Committee to compare elements of our executive compensation program to those of our peers and made other recommendations to the Compensation Committee regarding certain aspects of our executive compensation program. In making decisions regarding the form and amount of compensation to be paid to our executives, the Compensation Committee considers the information gathered by, and the recommendations of, Radford.








Processes and Procedures for Consideration and Determination of Director Compensation. The Board has delegated to the Compensation Committee the responsibility, among other things, to establish and lead a process for determination of compensation payable to our non-employee directors. The Compensation Committee makes recommendations regarding compensation payable to our non-employee directors to the entire Board, which then makes the final decisions.



In making decisions regarding compensation to be paid to our non-employee directors, the Board considers the recommendations of Radford, but also other factors, such as its own views as to the form and amount of compensation to be paid, the current and anticipated time demands placed on non-employee directors and other factors that may be relevant.



Nominating and Corporate Governance Committee



Responsibilities. The primary responsibilities of the Nominating and Corporate Governance Committee are:



| | ● | identifying individuals qualified to become Board members;
| | - | ----------------------------------------------------------



| | ● | recommending director nominees for each annual meeting of our stockholders and director nominees to fill any vacancies that may occur between meetings of stockholders;
| | - | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | ● | being aware of best practices in corporate governance and developing and recommending to the Board a set of corporate governance standards to govern the Board, its committees, our company and our employees in the conduct of our business and affairs; and
| | - | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | ● | developing and overseeing a Board and Board committee evaluation process.
| | - | -------------------------------------------------------------------------



The Nominating and Corporate Governance Committee has the authority to engage the services of outside experts and advisors as it deems necessary or appropriate to carry out its duties and responsibilities.



Composition. The current members of the Nominating and Corporate Governance Committee are Messrs. Adams, Giles and Levin. Mr. Giles is the chair of the Nominating and Corporate Governance Committee. Each of the three current members of the Nominating and Corporate Governance Committee is an “independent director” within the meaning of the Listing Rules of The NASDAQ Stock Market.



Meetings. The Nominating and Corporate Governance Committee met 6 times during 2016.



Director Nominations Process



In selecting nominees for the Board, the Nominating and Corporate Governance Committee first determines whether the incumbent directors are qualified to serve, and wish to continue to serve, on the Board. The Nominating and Corporate Governance Committee believes that our company and stockholders benefit from the continued service of qualified incumbent directors because those directors have familiarity with and insight into our company’s affairs that they have accumulated during their tenure with Diffusion. Appropriate continuity of Board membership also contributes to the Board’s ability to work as a collective body. Accordingly, it is the practice of the Nominating and Corporate Governance Committee, in general, to re-nominate an incumbent director at the upcoming annual meeting of stockholders if the director wishes to continue his or her service with the Board, the director continues to satisfy the Nominating and Corporate Governance Committee’s criteria for membership on the Board, the Nominating and Corporate Governance Committee believes the director continues to make important contributions to the Board and there are no special, countervailing considerations against re-nomination of the director.








In identifying and evaluating new candidates for election to the Board, the Nominating and Corporate Governance Committee intends to first solicit recommendations for nominees from persons whom the Nominating and Corporate Governance Committee believes are likely to be familiar qualified candidates having the qualifications, skills and characteristics required for Board nominees from time to time. Such persons may include members of the Board and senior management of Diffusion. In addition, the Nominating and Corporate Governance Committee may engage a search firm to assist it in identifying qualified candidates. The Nominating and Corporate Governance Committee then intends to review and evaluate each candidate whom it believes merits serious consideration, taking into account available information concerning the candidate, any qualifications or criteria for Board membership established by the Nominating and Corporate Governance Committee, the existing composition of the Board and other factors that it deems relevant. In conducting its review and evaluation, the Nominating and Corporate Governance Committee may solicit the views of our management, other Board members and any other individuals it believes may have insight into a candidate. The Nominating and Corporate Governance Committee may designate one or more of its members and/or other Board members to interview any proposed candidate.



The Nominating and Corporate Governance Committee will consider recommendations for the nomination of directors submitted by our stockholders. The Nominating and Corporate Governance Committee will evaluate candidates recommended by stockholders in the same manner as those recommended as stated above.



There are no formal requirements or minimum qualifications that a candidate must meet in order for the Nominating and Corporate Governance Committee to recommend the candidate to the Board. The Nominating and Corporate Governance Committee believes that each nominee should be evaluated based on his or her merits as an individual, taking into account the needs of the Company and the Board. However, in evaluating candidates, there are a number of criteria that the Nominating and Corporate Governance Committee generally views as relevant and is likely to consider. Some of these factors include:



| | ● | whether the candidate is an “independent director” under applicable independence tests under the federal securities laws and rules and regulations of the SEC;
| | - | --------------------------------------------------------------------------------------------------------------------------------------------------------------



| | ● | whether the candidate is “financially sophisticated” and otherwise meets the requirements for serving as a member of an audit committee;
| | - | ----------------------------------------------------------------------------------------------------------------------------------------



| | ● | whether the candidate is an “audit committee financial expert” under the rules and regulations of the SEC;
| | - | ----------------------------------------------------------------------------------------------------------



| | ● | the needs of the Company with respect to the particular talents and experience of our directors;
| | - | ------------------------------------------------------------------------------------------------



| | ● | the personal and professional integrity and reputation of the candidate;
| | - | ------------------------------------------------------------------------



| | ● | the candidate’s level of education and business experience;
| | - | -----------------------------------------------------------



| | ● | the candidate’s business acumen;
| | - | --------------------------------



| | ● | the candidate’s level of understanding of our business and industry and other industries relevant to our business;
| | - | ------------------------------------------------------------------------------------------------------------------



| | ● | the candidate’s ability and willingness to devote adequate time to the work of the Board and its committees;
| | - | ------------------------------------------------------------------------------------------------------------



| | ● | the fit of the candidate’s skills and personality with those of other directors and potential directors in building a board of directors that is effective, collegial and responsive to the needs of our company;
| | - | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | ● | whether the candidate possesses strategic thinking and a willingness to share ideas;
| | - | ------------------------------------------------------------------------------------








| | ● | the candidate’s diversity of experiences, expertise and background; and
| | - | -----------------------------------------------------------------------



| | ● | the candidate’s ability to represent the interests of all stockholders and not a particular interest group.
| | - | -----------------------------------------------------------------------------------------------------------



While we do not have a stand-alone diversity policy, in considering whether to recommend any director nominee, including candidates recommended by stockholders, the Nominating and Corporate Governance Committee will consider the factors above, including the candidate’s diversity of experiences, expertise and background. The Nominating and Corporate Governance Committee seeks nominees with a broad diversity of experience, expertise and backgrounds. The Nominating and Corporate Governance Committee does not assign specific weights to particular criteria and no particular criterion is necessarily applicable to all prospective nominees. We believe that the backgrounds and qualifications of the directors, considered as a group, should provide a significant mix of experience, knowledge and abilities that will allow the Board to fulfill its responsibilities.



Board Oversight of Risk



The Board as a whole has responsibility for risk oversight, with more in-depth reviews of certain areas of risk being conducted by the relevant Board committees that report on their deliberations to the full Board. The oversight responsibility of the Board and its committees is enabled by management reporting processes that are designed to provide information to the Board about the identification, assessment and management of critical risks and management’s risk mitigation strategies. The areas of risk that we focus on include regulatory, operational, financial (accounting, credit, liquidity and tax), legal, compensation, competitive, health, safety and environment, economic, political and reputational risks.



The standing committees of the Board oversee risks associated with their respective principal areas of focus. The Audit Committee’s role includes a particular focus on the qualitative aspects of financial reporting to stockholders, on our processes for the management of business and financial risk, our financial reporting obligations and for compliance with significant applicable legal, ethical and regulatory requirements. The Audit Committee, along with management, is also responsible for developing and participating in a process for review of important financial and operating topics that present potential significant risk to our company. The Compensation Committee is responsible for overseeing risks and exposures associated with our compensation programs and arrangements, including our executive and director compensation programs and arrangements, and management succession planning. The Nominating and Corporate Governance Committee oversees risks relating to our corporate governance matters and policies and director succession planning.



We recognize that a fundamental part of risk management is understanding not only the risks a company faces and what steps management is taking to manage those risks, but also understanding what level of risk is appropriate for our company. The involvement of the full Board in setting our business strategy is a key part of the Board’s assessment of management’s appetite for risk and also a determination of what constitutes an appropriate level of risk for our company.



We believe our current Board leadership structure is appropriate and helps ensure proper risk oversight for our company for a number of reasons, including: (1) general risk oversight by the full Board in connection with its role in reviewing our key long-term and short-term business strategies and monitoring on an on-going basis the implementation of our key business strategies; (2) more detailed oversight by our standing Board committees that are currently comprised of and chaired by our independent directors and (3) the focus of our Chairman of the Board on allocating appropriate Board agenda time for discussion regarding the implementation of our key business strategies and specifically risk management.



Code of Business Conduct and Ethics



Our Code of Business Conduct and Ethics applies to all of our directors, executive officers and other employees, and meets the requirements of the SEC. A copy of our Code of Business Conduct and Ethics will be available on the Investor Relations—Corporate Governance—Code of Business Conduct and Ethics section of our corporate website at www.diffusionpharma.com.








Process Regarding Stockholder Communications with Board of Directors



Stockholders may communicate with the Board or any one particular director by sending correspondence, addressed to our Secretary, Diffusion Pharmaceuticals Inc., 2020 Avon Court, Suite 4, Charlottesville, Virginia 22902, with an instruction to forward the communication to the Board or one or more particular directors. Our Secretary will forward promptly all such stockholder communications to the Board of Directors or the one or more particular directors, with the exception of any advertisements, solicitations for periodical or other subscriptions and other similar communications.

401(k) Retirement Plan



We maintain the Diffusion Pharmaceuticals Inc. 401(k) plan pursuant to which all eligible employees are entitled to make pre-tax and after-tax contributions of their compensation. In addition, the Company makes discretionary matching contributions at the rate of 100% for contributions up to 3% of the participant’s eligible compensation and 50% for any additional contributions up to 5% of the participant’s eligible compensation.

Post-Termination Severance and Change in Control Arrangements



Current Named Executive Officers



As described under the heading “—Employment Agreements,” we have entered into employment agreements with each of Messrs. Kalergis and Shealy and Dr. Gainer that provide for certain severance and change of control benefits, subject to the execution and non-revocation of a release of claims by the executive or his estate (as applicable). Under Mr. Kalergis’ employment agreement, if his employment is terminated by us other than for “cause,” death or “disability,” or by Mr. Kalergis for “good reason” (as such terms are defined in the employment agreement), Mr. Kalergis will be entitled to any unpaid bonus earned in the year prior to the termination, a pro-rata portion of the bonus earned during the year of termination, continuation of base salary for 12 months, plus 12 months of COBRA premium reimbursement, provided that if such termination occurs within 60 days before or within 24 months following a “change of control” (as defined in the employment agreement), then Mr. Kalergis will be entitled to receive the same severance benefits as provided above, except that he will receive (a) a payment equal to two times the sum of his base salary and the higher of his target annual bonus opportunity and the bonus payment he received for the year immediately preceding the year in which the termination occurred instead of 12 months of base salary continuation, and (b) a payment equal to 36 times the monthly COBRA premium for him and his eligible dependents instead of 12 months of COBRA reimbursements (the payments in clauses (a) and (b) are paid in a lump sum in some cases and partly in a lump sum and partly in installments over 12 months in other cases). In addition, if Mr. Kalergis’ employment is terminated by us without cause or by Mr. Kalergis for good reason, in either case, upon or within 24 months following a change of control, then Mr. Kalergis will be entitled to full vesting of all equity awards received by him from us (with any equity awards that are subject to the satisfaction of performance goals deemed earned at not less than target performance, and with any equity award that is in the form of a stock option or stock appreciation right to remain outstanding and exercisable for 24 months following the termination date (but in no event beyond the expiration date of the applicable option or stock appreciation right)).



Under the employment agreements for Mr. Shealy and Dr. Gainer, in the event that the executive’s employment is terminated by us other than for “cause”, death or "disability” or upon his resignation for “good reason” (as such terms are defined in the applicable employment agreement), the executive will be entitled to any unpaid bonus earned in the year prior to the termination, a pro-rata portion of the bonus earned during the year of termination, continuation of base salary for 9 months, plus 12 months of COBRA premium reimbursement, provided that if such termination occurs within 60 days before or within 24 months following a “change of control” (as defined in the applicable employment agreement), then the executive will be entitled to receive the same severance benefits as provided above, except that he will receive (a) a payment equal to 1.5 times the sum of his base salary and the higher of his target annual bonus opportunity and the bonus payment he received for the year immediately preceding the year in which the termination occurred instead of 9 months of base salary continuation and (b) a payment equal to 18 times the monthly COBRA premium for the executive and his eligible dependents instead of 12 months of COBRA reimbursements (the payments in clauses (a) and (b) are paid in a lump sum in some cases and in installments over 9 or 12 months in other cases). In addition, if the executive’s employment is terminated by the Company without cause or by the executive for good reason, in either case, upon or within 24 months following a change of control, then the executive will be entitled to full vesting of all equity awards received by the executive from us (with any equity awards that are subject to the satisfaction of performance goals deemed earned at not less than target performance, and with any equity award that is in the form of a stock option or stock appreciation right to remain outstanding and exercisable for 24 months following the termination date (but in no event beyond the expiration date of the applicable option or stock appreciation right)).



Under the employment agreements for each of Messrs. Kalergis and Shealy and Dr. Gainer, in the event that the executive’s employment is terminated due to his death or disability, he (or his estate) will be entitled to any unpaid bonus earned in the year prior to the termination, a pro-rata portion of the bonus earned during the year of termination, 12 months of COBRA premium reimbursement and accelerated vesting of (a) all equity awards received in payment of base salary or an annual bonus and (b) with respect to any other equity award, the greater of the portion of the unvested equity award that would have become vested within 12 months after the termination date had no termination occurred and the portion of the unvested equity award that is subject to accelerated vesting (if any) upon such termination under the applicable equity plan or award agreement (with performance goals deemed earned at not less than target performance, and with any equity award that is in the form of a stock option or stock appreciation right to remain outstanding and exercisable for 12 months following the termination date or, if longer, such period as provided under the applicable equity plan or award agreement (but in no event beyond the expiration date of the applicable option or stock appreciation right)).








Further, under the terms of the stock option agreements with our executives, upon a completion of a “change of control” (as defined in the Diffusion Pharmaceuticals Inc. 2015 Equity Incentive Plan), options held by our executives will become immediately vested and remain exercisable through their expiration date regardless of whether the holder remains in the employment or service of the Company. Alternatively, in connection with a change of control, the Compensation Committee may, in its sole discretion, cash out the options.



Pre-Merger Officers



Pursuant to their employment agreements, upon the termination of their employment in connection with the Merger, each of Messrs. Simes and Donenberg received 24 months of base salary, plus two times the executive’s target annual bonus, and Dr. Weinberg received 18 months of base salary. In addition, each of these three executives were entitled to up to 18 months of COBRA premium reimbursement. Pursuant to their employment agreements, each of these executives are subject to certain confidentiality and assignment of inventions provisions. Furthermore, under the terms of their stock option agreements, options held by these executives became immediately vested in connection with the Merger and remain exercisable through their applicable expiration date. The total severance amounts paid to each of Messrs. Simes and Donenberg and Dr. Weinberg upon their termination of employment in connection with the Merger are reported in the Summary Compensation Table above.








DIRECTOR COMPENSATION



Overview of Director Compensation Program



As described in more detail under the heading “The Board, Its Committees and Corporate Governance—Compensation Committee—Responsibilities,” the Board has delegated to the Compensation Committee the responsibility, among other things, to establish and lead a process for the determination of compensation payable to our non-employee directors. The Compensation Committee makes recommendations regarding compensation payable to our non-employee directors to the entire Board, which then makes final decisions regarding such compensation.



The principal elements of our director compensation program for 2016 included:



| | ● | cash compensation in the form of annual cash retainers; and
| | - | -----------------------------------------------------------



| | ● | long-term equity-based incentive compensation, in the form of stock options.
| | - | ----------------------------------------------------------------------------



We do not compensate our employee directors, Mr. Kalergis and Dr. Gainer, separately for serving on the Board. In addition, pursuant to the option agreement between the Company and Mr. Blech described below, Mr. Blech also does not receive the long-term incentive compensation and annual retainers otherwise payable to our non-employee directors.



Cash Compensation



The non-employee members of the Board were entitled to the following cash retainers for services in 2016:



|Description                                                             |  | AnnualCash Retainer |

|Board Member                                                            |  | $                   | 32,500
|Lead Independent Director of the Board                                  |  | $                   | 3,000 
|Audit Committee Chair                                                   |  | $                   | 15,000
|Compensation Committee Chair                                            |  | $                   | 10,000
|Nominating and Corporate Governance Committee Chair                     |  | $                   | 7,000 
|Audit Committee Member (other than Chair)                               |  | $                   | 6,000 
|Compensation Committee Member (other than Chair)                        |  | $                   | 5,000 
|Nominating and Corporate Governance Committee Member (other than Chair) |  | $                   | 3,000 



The annual cash retainers are paid on a quarterly basis in arrears at the end of each calendar quarter. For example, the retainers paid at the end of the first calendar quarter are for the period from January 1 through March 31. The Compensation Committee has also reserved the right to make all or a portion of such payments in the form of equity rather than cash under certain conditions. During the fiscal year 2016, all retainers were paid in options to purchase shares of our common stock. The shares underlying such option grants are scheduled to vest in equal parts each month over the 36 month period following the grant date.



Long-Term Equity-Based Incentive Compensation



In addition to cash compensation, our non-employee directors receive long-term equity-based incentive compensation in the form of options to purchase shares of our common stock. Upon a non-employee director’s initial appointment to the Board, he or she shall receive a stock option award valued at $100,000 vesting in equal annual installments over three years. In addition, each non-employee director receives annually a stock option award valued at $50,000 vesting in equal monthly installments over three years (unless otherwise provided by the Compensation Committee). All such options have a ten-year term and an exercise price equal to the fair market value of our common stock on the grant date.








See the Director Compensation Table under the heading “—Summary Director Compensation Table for Fiscal 2016” for a summary of all options granted to our non-employee directors during the year ended December 31, 2016. See note 3 to the Director Compensation Table under the heading “—Summary Director Compensation Table for Fiscal 2016” for a summary of all options to purchase shares of our common stock held by our non-employee directors as of December 31, 2016.



Blech Option Agreement



In connection with his appointment to the Board on August 11, 2016 and in lieu of the compensation otherwise payable to our non-employee directors as described above, Mr. Blech was granted on August 31, 2016 a one-time stock option grant to purchase 204,907 shares of our common stock, which shares shall vest in equal quarterly installments over 10 years beginning September 30, 2016 (the “Blech Option Grant”). Mr. Blech generally has agreed not to sell any of the shares issuable upon exercise of the Blech Option Grant until August 11, 2021.



Indemnification Agreements



We have entered into agreements with each of the members of the Board under which we are required to indemnify them against expenses, judgments, penalties, fines, settlements and other amounts actually and reasonably incurred, including expenses of a derivative action, in connection with an actual or threatened proceeding if any of them may be made a party because he or she is or was one of our directors. We will be obligated to pay these amounts only if the director acted in good faith and in a manner that he or she reasonably believed to be in or not opposed to our best interests. With respect to any criminal proceeding, we will be obligated to pay these amounts only if the director had no reasonable cause to believe his or her conduct was unlawful. The indemnification agreements also set forth procedures that will apply in the event of a claim for indemnification.

Security Ownership of Certain Beneficial Owners and Management



Based on information available to us and filings with the SEC, the following table sets forth certain information regarding the beneficial ownership (as defined by Rule 13d-3 under the Exchange Act) of our outstanding common stock and Series A convertible preferred stock (the “Series A Preferred Stock”) as of April 17, 2017 for (i) each person who beneficially owns 5% or more of the shares of common stock or Series A Preferred Stock then outstanding; (ii) each of our current directors and nominees; (iii) each of our current named executive officers (as defined in Item 402(a)(3) of Regulation S-K under the Exchange Act); and (iv) all of our current directors and executive officers as a group.



Beneficial ownership and percentage ownership are determined in accordance with the rules of the SEC and include voting or investment power with respect to shares of stock. This information does not necessarily indicate beneficial ownership for any other purpose. Under these rules, shares of common stock issuable under stock options, the Series A Preferred Stock, our convertible debt instruments or warrants that are exercisable or convertible within 60 days of April 17, 2017 are deemed outstanding for the purpose of computing the beneficial ownership percentage of the holder thereof, but are not deemed outstanding for the purpose of computing the beneficial ownership percentage of any other person. Ownership is based upon information provided by each respective director and officer, Forms 4, Schedules 13D and 13G and other public documents filed with the SEC for some of the stockholders.



Unless otherwise indicated and subject to applicable community property laws, to our knowledge, each stockholder named in the following table possesses sole voting and investment power over their shares of common stock, except for those jointly owned with that person’s spouse. Unless otherwise indicated below, the address of each person listed on the table is c/o Diffusion Pharmaceuticals Inc. 2020 Avon Court, Suite 4, Charlottesville Virginia 22902.

Item 14.Principal Accountant Fees and Services



Change and Selection of Independent Registered Public Accounting Firm



On January 8, 2016, after the completion of the Merger, the Audit Committee of the Board (i) approved the dismissal of Deloitte & Touche LLP (“Deloitte”) as the Company’s independent registered public accounting firm effective as of the date of Deloitte’s completion of the audit services for the year ended December 31, 2015 and the filing of the Company’s annual report on Form 10-K for the year ended December 31, 2015 and (ii) appointed KPMG LLP (“KPMG”) as the Company’s independent registered public accounting firm for the year ending December 31, 2016. On March 25, 2016, the Company filed its annual report on Form 10-K for the year ended December 31, 2015.



Deloitte was initially engaged by the Company on November 20, 2014 and served as the Company’s independent registered public accounting firm for the year ended December 31, 2015. Deloitte’s report on the Company’s consolidated financial statements for the fiscal year ended December 31, 2015 did not contain an adverse opinion or disclaimer of opinion, nor was the report qualified or modified as to uncertainty, audit scope or accounting principles, except that Deloitte’s report includes explanatory paragraphs relating to the ability of the Company to continue as a going concern and the acquisition of Diffusion LLC pursuant to the Merger in January 2016.



During the fiscal year ended December 31, 2015 and the subsequent interim period prior to the Company’s dismissal of Deloitte on March 25, 2016, there were no: (i) disagreements with Deloitte on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedure which, if not resolved to the satisfaction of Deloitte, would have caused Deloitte to make reference to the matter in their report, or (ii) reportable events as defined in Item 304(a)(1)(v) of Regulation S-K.



During the fiscal year ended December 31, 2015 and the subsequent interim period prior to the Company’s engagement of KPMG, neither the Company nor anyone acting on its behalf consulted KPMG regarding either: (i) the application of accounting principles to a specific transaction, either completed or proposed, or the type of audit opinion that might be rendered on the Company’s consolidated financial statements, and either a written report was provided to the Company or oral advice was provided that KPMG concluded was an important factor considered by the Company in reaching a decision as to the accounting, auditing or financial reporting issue; or (ii) any matter that was either the subject of a disagreement (as defined in Item 304(a)(1)(iv) of Regulation S-K) or a reportable event (as described in Item 304(a)(1)(v) of Regulation S-K).



Independent Auditor’s Fees



As we did not engage KPMG as our independent registered public accounting firm until after the completion of the Merger in January 2016, KPMG did not bill us for professional services during the year ended December 31, 2015. Accordingly, the table below presents fees billed to us for professional services rendered by KPMG, our current independent registered public accounting firm, for the year ended December 31, 2016 and by Deloitte, our former independent registered public accounting firm, for the year ended December 31, 2015.

|Audit Fees(1)      |  | $                       | 605,146
|Audit-Related Fees |  | $                       | 0      
|Tax Fees(2)        |  | $                       | 22,997

Audit fees for 2015 consisted of fees payable to Deloitte for the audit of our annual financial statements and the review of our quarterly financial information for the year ended December 31, 2015.

|--- | ---------------------------------------------------------------------------------------------------------



Pre-Approval Policies and Procedures



The Audit Committee has adopted procedures pursuant to which all audit, audit-related and tax services and all permissible non-audit services provided by our independent registered public accounting firm must be pre-approved by the Audit Committee. All services rendered by KPMG during 2016 were permissible under applicable laws and regulations and were approved in advance by the former Audit Committee in accordance with the rules adopted by the SEC in order to implement requirements of the Sarbanes-Oxley Act of 2002 other than de minimis non-audit services allowed under applicable law.
