PROPOSAL NO. 1 — APPROVAL OF AN AMENDMENT TO THE CERTIFICATE OF INCORPORATION TO INCREASE THE NUMBER OF AUTHORIZED SHARES OF
COMMON STOCK.
General
Our Board of Directors has approved, subject to stockholder approval, an amendment to our Certificate of Incorporation (the “Common Stock Increase Amendment”) to increase the number of authorized shares voted “for”, “against”, “abstaining” or “withheld from”of our common stock from 450,000,000 to 1,200,000,000 (“Proposal No. 1”). The Company’s Certificate of Incorporation currently authorizes the issuance of 450,000,000 shares of common stock, par value $0.001 per share (the “Common Stock”). As of March 23, 2018, we had 414,665,188 shares of Common Stock outstanding. The increase in our authorized shares of Common Stock will be effective upon the filing of the Common Stock Increase Amendment to the Certificate of Incorporation with respect to such non-routine matters.

Proposal 1: Electionthe Secretary of Dr. Alton L. BoyntonState of the State of Delaware.

Effects and Mr. Cofer BlackPurpose of the Increase in Authorized Common Stock
The additional shares of Common Stock will have the same rights as the Class Ipresently authorized shares, including the same voting rights, and rights to dividends and other distributions and will be identical in all other respects to our Common Stock now authorized.
As of March 23, 2018, the Company had 414,665,188 shares of Common Stock issued and outstanding. Given the Company’s need for additional available authorized shares of Common Stock to meet the Company’s capital needs, as well as the Company’s obligations in respect of its outstanding stock options, warrants and convertible securities, the Board of Directors

Under believes that the increase in the number of authorized shares of Common Stock is necessary and in the Company’s best interests.

Although the authorization of additional shares will not, in itself, have any effect on the rights of any holder of our bylaws,Common Stock, the Board of Directors may in the future issue the additional shares of Common Stock authorized by the Common Stock Increase Amendment to raise additional capital, to satisfy obligations in respect of its outstanding stock options, warrants and convertible securities, to provide equity incentives to employees, officers or directors or for other purposes.
If the Common Stock Increase Amendment is approved, the Company will have sufficient shares of Common Stock available to facilitate the following transactions on behalf of its investors:

the Company anticipates the conversion of all 3,486,302 outstanding shares of its Series A Preferred Stock and all 6,355,696 outstanding shares of its Series B Preferred Stock into shares of Common Stock, in each case at the rate of 10 shares of Common Stock for each share of Preferred Stock;

the Company can accommodate the exercise (which will be at the election of the holders) of any of the 333.7 million of outstanding warrants, most of which are currently subject to limitations on exercise related to the availability of common shares;

the 42,506,716 stock options which were awarded to directors requiresand officers as equity compensation and vested can become exercisable, and the 33,516,401 stock options which are vesting monthly over periods of up to 23 months can become exercisable after they have vested; and

holders of other convertible securities of the Company may convert such securities into common shares and warrants of the Company, as applicable.
In addition to the potential issuances listed above, which the Company anticipates may take place if the Common Stock Increase Amendment is approved, the Company also anticipates issuances in ongoing financings in connection with the Company’s clinical trial programs and operations. The Company does not currently have specific plans for a significant financing, but will need to raise further funding over the course of this year as it has done in preceding years.
Although the increased proportion of unissued authorized shares to issued shares could, under certain circumstances, have or be used for an anti-takeover effect, the Common Stock Increase Amendment is not being proposed in response to any effort of which the Company is aware to accumulate shares of our Common Stock or obtain control of the Company.

TABLE OF CONTENTS
Our Common Stock is currently registered under the Securities Exchange Act of 1934, as amended, and the Company is subject to the periodic reporting and other requirements of the Exchange Act. The Common Stock Increase Amendment will not affect the registration of the Company’s Common Stock under the Exchange Act.
No Appraisal Rights
No stockholder appraisal rights will be applicable in connection with the Common Stock Increase Amendment.
Implementation of the Common Stock Increase Amendment
If the Common Stock Increase Amendment is approved at the Special Meeting, our Board intends to implement the Common Stock Increase Amendment by filing an amendment to our Certificate of Incorporation with the Secretary of State of the State of Delaware as contemplated by the proposed form of  “Certificate of Amendment” attached hereto as Appendix A.

PROPOSAL NO. 2 — APPROVAL OF AN AMENDMENT TO THE CERTIFICATE OF INCORPORATION TO INCREASE THE NUMBER OF AUTHORIZED SHARES OF
PREFERRED STOCK.
General
Our Board of Directors has approved, subject to stockholder approval, an amendment to our Certificate of Incorporation (the “Preferred Stock Increase Amendment”) to increase the number of authorized shares of our preferred stock from 40,000,000 to 100,000,000 (“Proposal No. 2”). The Company’s Certificate of Incorporation currently authorizes the issuance of 40,000,000 shares of Preferred Stock, par value $0.001 per share (the “Preferred Stock”). As of March 23, 2018, we had 3,486,302 shares of Series A Preferred Stock outstanding and 6,355,696 shares of Series B Preferred Stock outstanding. The increase in our authorized shares of Preferred Stock will be effective upon the filing of the Preferred Stock Increase Amendment to the Certificate of Incorporation with the Secretary of State of the State of Delaware.
Effects and Purpose of the Increase in Authorized Preferred Stock
The additional shares of authorized Preferred Stock would be able to be issued with such designations, preferences and relative, participating, optional, conversion or absenceother special rights (if any) of such series and the qualifications, limitations or restrictions (if any) thereof, as the Board of Directors may in the future establish by resolution or resolutions and by filing a certificate pursuant to the Delaware General Corporation Law (a “Preferred Stock Designation”), from time to time providing for the issuance of such Preferred Stock. No vote of the holders of the Common Stock or the Preferred Stock, unless otherwise expressly provided in a Preferred Stock Designation creating any series of Preferred Stock, will be a prerequisite to the issuance of any shares of any series of the Preferred Stock authorized by and complying with the conditions of the Certificate of Incorporation.
The Board’s objective in approving the Preferred Stock Increase Amendment to increase the authorized shares of Preferred Stock is to provide maximum flexibility with respect to future financing transactions. Preferred Stock is commonly authorized by publicly traded companies and is sometimes used as a preferred means of raising capital. In some circumstances, companies, including us, have been required to utilize senior classes of securities to raise capital, with the terms of those securities being negotiated and tailored to meet the needs of both investors and issuing companies. Such senior securities often include liquidation preferences and dividend rights, conversion privileges and other rights not found in Common Stock.
If the Preferred Stock Increase Amendment is approved, the Company anticipates issuances in ongoing financings in connection with the Company’s clinical trial programs and operations. The Company does not currently have specific plans for a significant financing, but will need to raise further funding over the course of this year as it has done in preceding years.
No Appraisal Rights
No stockholder appraisal rights will be applicable in connection with the Preferred Stock Increase Amendment.
Implementation of the Preferred Stock Increase Amendment
If the Preferred Stock Increase Amendment is approved at the Special Meeting, our Board intends to implement the Preferred Stock Increase Amendment by filing an amendment to our Certificate of Incorporation with the Secretary of State of the State of Delaware as contemplated by the proposed form of  “Certificate of Amendment” attached hereto as Appendix A.

PROPOSAL NO. 3 — APPROVAL OF OPTION AWARDS TO THE INDEPENDENT DIRECTORS OF THE BOARD OF DIRECTORS OF THE COMPANY
General
The Company’s compensation philosophy is to ensure that the Company’s compensation and benefits policies attract and retain the key employees and independent directors necessary to support the Company’s growth and success, both operationally and strategically, and motivate its key employees and independent directors to achieve short- and long-term goals to help build stockholder value.
At present, two of our five Board members are drawn from Company management and serve ex officio, and three of our Board members are “independent” as that term is defined within the meaning of Section 5605(a)(2) of the NASDAQ Marketplace Rules.
The Company’s ex officio Directors do not receive any compensation for their service on the Board. The Company’s independent directors are supposed to receive a combination of cash and equity compensation. However, to date the independent directors have received no equity compensation, and the cash portion of their compensation has been delayed for months and in some cases years (and is currently substantially in arrears).
Two of the independent directors, Mr. Jasinowski and Dr. Malik, have now been serving on the Company’s Board for approximately 6 years. The third independent director, Ambassador Black, has been serving for approximately 2 years. The Company promised equity compensation when they joined the Board years ago, and the Company has continued to promise equity compensation throughout their years of service.
In determining the independent directors’ compensation, we take into account market data and practices, and we evaluate and compare the nature and scope of responsibilities undertaken and contributions made by our independent directors in helping to support the Company and its operations. We reviewed information about director compensation arrangements at a number of other biotech and pharmaceutical companies in our peer group, and information about the extent of the directors’ activities in those companies, based upon the companies’ public filings. We also compared the nature and extent of those directors’ involvement with the involvement of the independent directors in our Company.
Determination of Our Directors’ Equity Compensation
On February 26, 2018, the disinterested members of the Company’s Board of Directors approved option awards for the independent directors, subject to shareholder approval at the Special Meeting (the “Options”).
The Option awards were based on a number of factors and considerations. One consideration was the extraordinarily long period that the independent directors have been serving without having received any equity compensation, despite the Company’s promises to make such awards. The awards being made now are taking account of the independent directors’ years of service to date, as well as the continuation of their service going forward.
Another set of considerations in determining the Option awards was the extraordinary amount time, effort and support contributed by the independent directors throughout their respective periods of service, going far beyond the activities typically involved in Board service. For example, while an average board of directors might meet four to six times a year, our Board meets on average at least two dozen times per year, sometimes more. In addition, the independent directors have provided active support and assistance to management in a variety of areas, including financing.
A further set of considerations in regard to the Option awards involves the extent of personal and professional risk our independent directors have endured in serving on our Board. Our Company has experienced ongoing attacks from short sellers and from bloggers, whom the Company believes may be connected with short sellers. The attacks have also gone beyond the Company itself: aggressive personalized attacks have been made against our directors individually, on a personalized basis, in blogs, social media and message boards. Further, our Company has been subjected to multiple lawsuits which we believe were

without merit, which we fought vigorously and settled favorably — but which named our directors personally and put them at personal risk. To our knowledge, virtually no directors of other companies in our peer group have had to put up with anything like these personalized attacks and lawsuits, as our directors have.
Of special note, in addition to undertaking far more activities in support of the Company’s operations than would normally be expected of directors, enduring attacks and lawsuits, tolerating long delays in their cash compensation and waiting for as long as 6 years for the Company to implement their equity compensation, the directors have also provided personal loans to the Company to help it survive, on terms far more favorable to the Company than market based terms, and allowed such loans to remain outstanding and unpaid long after they were due.
For all of the above reasons, the disinterested directors approved the Options, subject to shareholder approval, and our management also strongly supports the Option awards.
Summary of the Stock Option Awards
The Options are not currently exercisable and will become exercisable only when shares of Common Stock are available for issuance. The Options will be exercisable for Common Stock of the Company at the same price per share as the Common Stock into which the Series B Preferred Stock is convertible, which the Company has sold to investors: $0.23 per share of Common Stock. The Options will have an exercise period of ten years from the time they become exercisable. Half of the Options are vested at the time of issuance and half will vest monthly over the course of 24 months after issuance, subject to acceleration in certain circumstances.
The Options awarded to Mr. Jerry Jasinowski will be exercisable for up to 4,900,000 shares of Common Stock. The Options awarded to Dr. Navid Malik will be exercisable for up to 9,065,000 shares of Common Stock. The Options awarded to Ambassador J. Cofer Black will be exercisable for up to 1,715,000 shares of Common Stock.
Shareholder Action
We are asking stockholders to consider and approve the stock option awards to the independent members of the Company’s Board of Directors as described above in this Proposal No. 3.

No stockholder appraisal rights will be applicable in connection with the approval of the stock option awards to our independent directors.

Ms. Powers serves on the boards of several private biotechnology companies. Ms. Powers holds a B.A. from Princeton University, where she graduated magna cum laude and Phi Beta Kappa. She also earned a J.D., magna cum laude, from Harvard Law School. We believe Ms. Powers’ background and experience make her well qualified to serve as a Director.

Dr. Boynton also served as Director of the Department of Molecular Medicine of Northwest Hospital from 1995 to 2003 where he coordinated the establishment of a program centered on carcinogenesis.

Dr. Boynton received his Ph.D. in Radiation Biology from the University of Iowa in 1972. We believe Dr. Boynton’s background and experience make him well qualified to serve as a Director.

Robert A. Farmer.  Mr. Farmer was appointed to the Board of Directors in December 2009. Currently, and during the past five years, Mr. Farmer has served on the boards of directors of International Data Group, Dale Carnegie Associates, Sober Steering Sensors, LLC, Charlesbridge Publishing, and Haute Living.

President Clinton appointed Mr. Farmer as the United States Consul General to Bermuda, where he served from 1994 to 1999. Mr. Farmer also had a successful career as an entrepreneur, including building his own publishing company, which he sold in 1983. Mr. Farmer


is a graduate of Dartmouth College and Harvard Law School. We believe Mr. Farmer’s background and experiences in finance and as an entrepreneur, as well as his service on other boards of directors, make him well qualified to serve as a Director.

Jerry Jasinowski.  Mr. Jasinowski was appointed to the Board of Directors in April 2012. Mr. Jasinowski retired in 2007.

Mr. Jasinowski holds an A.B. in Economics from Indiana University and an M.A. in Economics from Columbia University. We believe that Mr. Jasinowski’s extensive experience across a wide range of manufacturing, technology, and financial firms, including Fortune 1000 and Fortune 500 companies, make him well qualified to serve as a Director.

CORPORATE GOVERNANCE MATTERS

Board Leadership Structure

The Board believes that Ms. Powers’ service as both ChairpersonPercentage represents beneficial ownership percentage of the Board and Chief Executive Officer is in the Company’s best interest and our stockholders’ best interests. Ms. Powers possesses detailed and in-depth knowledge of the issues, opportunities, and challenges facing us, and is thus, we believe, best positioned to develop Company strategies, business plans and priorities, and corresponding Board agendas that ensure that the Board’s time and attention are focused on the most critical matters. The Company has multiple major programs under way, with operations and infrastructure on two continents, which we believe is unusual for a small biotech company and requires heightened efficiency and involvement between the Board and management. Ms. Powers’ combined role enables decisive leadership, and, we believe, facilitates this efficiency and involvement. The Board has not appointed a lead independent director.

Board of Directors’ Role in Risk Oversight

The Board plays an active role in risk oversight of our Company. The Board does not have a formal risk management committee, but administers this oversight function through various standing committees of the Board of Directors. The Audit Committee maintains responsibility for oversight of financial reporting-related risks, including those related to our accounting, auditing and financial reporting practices. The Audit Committee also reviews reports and considers any material allegations regarding potential violations of our Company’s Code of Ethics. The Compensation Committee oversees risks arising from our compensation policies and programs. This Committee has responsibility for evaluating and approving our executive compensation and benefit plans, policies and programs.

Director Independence

Our Board of Directors has undertaken a review of the independence of our directors and has determined that a majority of the Board consists of members who are currently “independent” as that term is defined within the meaning of Section 5605(a)(2) of the NASDAQ Marketplace Rules. The Board of Directors has determined that each of Messrs. Farmer, Malik, Jasinowski, Black and Ms. Bayh is independent.

Audit Committee

The Audit Committee has responsibility for recommending the appointment of our independent accountants, supervising our finance function (which includes, among other matters, our investment activities), reviewing our internal accounting control policies and procedures, and providing the Board such additional information and materials as it may deem necessary to make the Board aware of significant financial matters which require the attention of the Board. The Audit Committee acts under a written charter.

The Audit Committee currently consists of Messrs. Farmer, Malik and Jasinowski. Our Board of Directors has determined that Jerry Jasinowski, the Chairman of the Audit Committee, qualifies as an “audit committee financial expert” as defined by the SEC. Our Board has undertaken a review of the independence of our directors and has determined that Messrs. Farmer, Malik and Jasinowski are independent within the meaning of Section 5605(a)(2) of the NASDAQ Marketplace Rules as well as pursuant to the additional test for independence for audit committee members imposed by SEC regulation and Section 5605(c)(2)(A) of the NASDAQ Marketplace Rules. The Audit Committee is establishedCommon Stock calculated in accordance with Section 3(a)(58)(A)SEC rules and does not equate to voting percentages. Percentage is based upon 414,665,188 shares of Common Stock issued and outstanding as of March 23, 2018. Beneficial ownership is determined in accordance with the rules of the Securities and Exchange Act. Mr. Jasinowski serves as financial expert on the Audit Committee.

Compensation Committee

The Compensation Committee is responsible for determining the overall compensation levels of our executive officers and administering our stock option plans. Ms. Powers, our Chairperson, President and Chief Executive Officer, participated in discussions regarding salaries and incentive compensation for all of our executive officers, except that she was and is excluded from discussions regarding her own salary and incentive compensation. The Board has adopted a written charter for the Compensation Committee and its current members are Messrs. Farmer, Malik and Jasinowski. The Compensation Committee does not delegate its authority pursuant to its written charter. Our Board of Directors has determined that all of the members are “independent” under the current listing standards of NASDAQ.
