The change of control agreements provide for the following severance benefits: (1) a lump sum payment equal to one and one-half times the sum of (a) the higher of (i) the employee's annual base salary or (ii) the employee's base salary immediately prior to the change of control plus (b) the employee's average bonuses for the 3 most recently-ended fiscal years prior to the change of control; (2) the continuation of employee benefit programs (including medical and dental insurance, disability and life insurance benefits and car allowance programs) for a period of 18 months; (3) any compensation previously deferred by the employee; (4) accelerated vesting of all outstanding stock options held by the employee; and (5) the payment by the Company of up to $25,000 for placement services provided to the employee. In addition, if payments to the employee under his change of control agreement (together with any other payments or benefits) would trigger the provisions of Section 4999 of the Internal Revenue Code of 1986, as amended, the amount paid to the employee is increased so that the employee receives, net of excise taxes and any penalties, the amount he would have been entitled to receive in the absence of the excise tax. In the event Messrs. McLain, Farley and Muth and/or Dr. Naso are entitled to receive compensation and other benefits under their respective change of control agreements as well as severance or other benefits under an employment contract with the Company, they would be entitled to receive payment under whichever agreement would provide the greater value. Compensation Committee Report Executive compensation levels are based on a compensation program developed by the Compensation Committee in February 1993, which was modified in 1998 with respect to equity incentive compensation. Management Compensation Program. The Company's Management Compensation Program (the "Program") was developed by the Compensation Committee with the assistance of an outside compensation consultant and the Company's Vice President of Human Resources, and incorporates the results of a study undertaken by the American Compensation Association of executive compensation practices. The Program, which is based upon the compensation practices of comparable companies included in the study, is founded on the following principles. First, a strong link should be developed between planned organizational goals and individual compensation. Second, the Company should assure total compensation opportunities that are above comparable companies when the Company's performance is superior to theirs and below such comparators if the Company's performance is inferior to theirs. Third, the Company's compensation program should allow it to attract and retain individuals whose performance will enhance the profitability of the Company and, thus, stockholder value. The Company uses a comparator group of companies in the pharmaceutical/healthcare industry (the "Comparator Group") to serve as the basis for determining the appropriate cash element of the Program (base compensation and bonus). The companies in the Comparator Group are selected from the pharmaceutical/ healthcare industry based on their similarity to the Company as determined by total revenue. Base salary, annual bonus and equity incentive compensation, the three components of executive officers' compensation provided under the Program for 2000, are discussed below. Base salary and equity incentive compensation for 2000 were established by the Compensation Committee in early 2000 based on prior years' performance and the additional factors discussed below. Base Compensation. The Program is targeted to establish conservative base salaries set at 90% of the median salary levels of the Comparator Group. The Compensation Committee makes salary decisions based on a structured annual review with input from the Chief Executive Officer for the other executive officers as deemed appropriate. Three equally weighted 8

criteria, performance relative to corporate budgets, performance on specific projects and management attributes/skills performance, are the measurement factors used to make base salary decisions. Annual Bonus. Annual cash bonuses are provided to reward the attainment of planned operating goals based on revenue and profitability (pretax income as a percentage of revenue) and specified individual goals, with increased bonus amounts when performance is above the planned operating goals. For fiscal year 2000, if planned operating goals were attained or exceeded, the executives were eligible to receive cash bonuses ranging up to 125% of their base salaries. Equity Incentive Compensation. The long-term performance-based compensation of executive officers takes the form of option awards under the Company's stock option plans. The Compensation Committee believes that this equity-based compensation ensures that the Company's executive officers have a continuing stake in the long-term success of the Company. All options granted by the Company have been granted with an exercise price equal to or in excess of the market price of the Company's Common Stock at the time of the grant. Accordingly, stock options will have value only if the Company's stock price increases. Vesting is used to encourage employees to continue in the employ of the Company. In 2000, the Compensation Committee approved the issuance of options to these officers in order to provide them with a continuing incentive to perform and to further align their interests with those of the Company's stockholders. Other Compensation. The Compensation Committee is authorized to make discretionary compensation awards from time to time, including restricted stock awards. Chief Executive Officer Compensation. Mr. Gury's 2000 base salary was approximately 90% of the median level of the base salaries in the Comparator Group. In 1999, Mr. Gury's base salary also was approximately 90% of the median level.

AUDIT COMMITTEE REPORT The Audit Committee of the Board of Directors assists the Board of Directors in fulfilling its oversight responsibility to our shareholders with respect to Nabi's accounting functions and internal controls. The Audit Committee oversees our financial reporting process on behalf of our Board of Directors, reviews our financial disclosures, and meets privately, outside the presence of our management, with our independent public accountants to discuss the overall scope and plans for their audit, our internal accounting control policies, and procedures and the overall quality of the Company's financial reporting. In fulfilling its oversight responsibilities, the Audit Committee reviews the audited financial statements in the Annual Report on Form 10-K with management, including a discussion of the quality, not just the acceptability, of the accounting principles, the reasonableness of significant judgments, and the clarity of disclosures in the financial statements. The Audit Committee reports on its activities to our Board of Directors. The Audit Committee also considers and recommends the selection of our independent public accountants, reviews the performance of the independent public accountants in the annual audit and in assignments unrelated to the audit, and reviews the independent public accountants' fees. Nabi's Board of Directors has adopted a written charter for the Audit Committee, a copy of which is attached as Appendix A to this proxy statement. The Audit Committee is composed of three non-employee directors, each of whom is independent, as defined by the applicable listing standards of the National Association of Securities Dealers. During fiscal year 2000, the Audit Committee held six meetings. The meetings were designed to facilitate and encourage private communication between the members of the Audit Committee, our management, and our independent public accountants, Ernst & Young LLP. The Audit Committee reviewed with the independent public accountants, who are responsible for expressing an opinion on the conformity of its audited financial statements with generally accepted accounting principles, their judgments as to the quality, not just the acceptability of the Company's accounting principles and such matters as are required to be discussed with the Audit Committee under generally accepted auditing standards. In addition, the Audit Committee has discussed with the independent public accountants the independent public accountants' independence from Nabi and its management, including the matters in the written disclosures we received from the independent public accountants as required by Independence Standards Board Standard No. 1, "Independence Discussions with Audit Committees," and considered the compatibility of non-audit services with the independent public accountants' independence. Based on its review and discussions referred to above, the Audit Committee recommended to the Board of Directors that the audited financial statements be included in our Annual Report on Form 10-K for the fiscal year ended December 30, 2000. The Audit Committee recommended and the Board of Directors has appointed, Ernst & Young LLP to serve as the independent certified public accountants of the Company for the ensuing year. Respectfully submitted by, THE AUDIT COMMITTEE, David L. Castaldi, Chairman Geoffrey F. Cox, Ph.D. Linda Jenckes 10

Appendix A NABI AUDIT COMMITTEE CHARTER This Charter governs the operations of Nabi's (the "Company") Audit Committee of the Board of Directors (the "Committee"). The Committee will review the Charter at least annually and obtain the approval of the Charter by the Board of Directors. The Committee shall be appointed by the Board of Directors and shall be composed of three non-employee directors, each of whom is independent of management and the Company. A Chairman will be either designated by the Board of Directors or elected by the Committee by majority vote. For purposes of this Charter, independence has the same meaning as that in the National Association of Securities Dealers' listing standards. All Committee members will be financially literate, or will become financially literate within a reasonable period of time after appointment to the Committee, and at least one member will have accounting or related financial management expertise. The Committee will provide assistance to the Board of Directors in fulfilling its oversight responsibility to the shareholders relating to the Company's financial statements and the financial reporting process, the systems of internal accounting and financial controls, the internal audit function and the annual independent audit of the Company's financial statements. In so doing, it is the responsibility of the Committee to maintain free and open communication between the Committee, independent auditors, the internal auditor and management of the Company. In discharging its oversight role, the Committee is empowered to investigate any matter brought to its attention with full access to all books, records, facilities, and personnel of the Company and the power to retain outside counsel, or other experts for this purpose. The primary responsibility of the Committee is to oversee the Company's financial reporting process on behalf of the Board of Directors and report the results of their activities to the Board of Directors. Management is responsible for preparing the Company's financial statements, and the independent auditors are responsible for auditing those financial statements. The Committee, in carrying out its responsibilities, believes its policies and procedures should remain flexible, in order to best react to changing conditions and circumstances. The Committee should take the appropriate actions to set the overall corporate "tone" for quality financial reporting, sound business risk practices, and ethical behavior. The following shall be the principal recurring processes of the Committee in carrying out its oversight responsibilities. The processes are set forth as a guide with the understanding that the Committee may supplement them as appropriate. . The Committee shall have a clear understanding with management and the independent auditors that the independent auditors are ultimately accountable to the Board of Directors and the Committee, as representatives of the Company's shareholders. The Committee shall have the ultimate authority and responsibility to evaluate and, where appropriate, replace the independent auditors subject to stockholders' approval. The Committee shall review with the auditors their independence from management and the Company and the matters included in the written disclosures required by the Independence Standards Board. Annually, the Committee will review and recommend to the Board of Directors the selection of the Company's independent auditors. . The Committee shall annually inform the independent auditors, the Chief Financial Officer, the Controller, and the most senior person responsible for internal audit activities, that they should promptly contact the Committee or its Chairman about any significant issues or disagreements concerning the Company's accounting practices or financial statements that is not resolved to their satisfaction. . The Committee shall discuss with the internal auditor and the independent auditors the overall scope and plans for their respective audits, including the adequacy of staffing and compensation. Also, the A-1

Committee will discuss with management, the internal auditor, and the independent auditors the adequacy and effectiveness of the accounting and financial controls, including the Company's system to monitor and manage business risk. Further, the Committee will meet separately with the internal auditor and the independent auditors, with and without management present, to discuss the results of their examinations. . The Committee shall direct the independent auditor to use its best efforts to perform reviews of interim financial information prior to disclosure by the Company of such information. The Committee shall review the quarterly interim financial statements with management and the independent auditors prior to the filing of the Company's Quarterly Report on Form 10-Q. Also, the Committee will discuss the results of the quarterly review and any other matters required to be communicated to the Committee by the independent auditors under generally accepted auditing standards. The Chair of the Committee may represent the entire Committee for the purposes of this review. . The Committee shall review with management and the independent auditors the financial statements to be included in the Company's Annual Report on Form 10-K, including their judgment about the quality, not just acceptability, of accounting principles, the reasonableness of significant judgments, and the clarity of the disclosures in the financial statements. Also, the Committee will discuss the results of the annual audit and any other matters required to be communicated to the Committee by the independent auditors under generally accepted auditing standards and consider whether it will recommend to the Board of Directors that the Company's audited financial statements be included in the Company's Annual Reports of Form 10-K. . The Audit Committee shall prepare for inclusion where necessary in a proxy or information statement of the Company relating to an Annual Meeting of security holders at which directors are to be elected, the report described in Item 306 of Regulation S-K.
