        <ExplanationTxt>GTI has a separate conflict of interest policy for its Board of Directors. Conflicts of interest must be reported immediately. If a conflict of interest is identified, it is discussed with the General Counsel to identify the proper course of remedial action. These actions may range from recusal in any business transactions involving GTI or the other interested organization, to withdrawing from involvement in the other organizations board of directors, to other actions that assure the conflict of interest, or even the appearance of a conflict of interest may be avoided. All GTI employees are covered by a separate written conflict of interest policy. Potential and actual employee conflicts of interest are reviewed by the General Counsel. All employees have the obligation to obtain the General Counsels prior written approval for all such activity. The failure to obtain the General Counsels prior written approval shall constitute grounds for immediate dismissal with cause. The directors annually complete a conflict of interest questionnaire. GTI employees annually complete a conflict of interest disclosure statement, and recertify compliance with the policy on a semi-monthly basis.</ExplanationTxt>

        <ExplanationTxt>The positions that were reviewed included the President and CEO, Chief Financial Officer, General Counsel and Secretary, Senior Vice President of Research Operations, and Senior Vice President of Corporate Development. Annually, an outside company, CBIZ, determines the appropriate total compensation ranges for the above positions. A recommendation for merit increases and bonuses is made to the Compensation Committee of the Board of Directors, annually, based on the external market study performed by CBIZ, the companys performance, and the individuals performance. The Compensation Committee determines the final merit increase and bonus amounts. Merit increases for both officers and managing directors are based on specific formulas which incorporate target amounts for each set of increases, and are increased or reduced companywide, based on the direction of the Compensation Committee. The Compensation Committee specifically approves compensation for officers and reviews all compensation for managing directors as well. Their actions are detailed in the Compensation Committee meeting minutes.</ExplanationTxt>
