Audit Committee and Audit Committee Financial Expert

      We have a separately designated standing Audit Committee established in accordance with section 3(a)(58)(A) of the Securities Exchange Act of 1934, as amended (“Exchange Act”). During the fiscal year ended December 31, 2003, the Audit Committee was comprised of William Cunningham, Ph.D., Charles E. Long and Robert L. Moore. In February 2004, S. Malcolm Gillis, Ph.D. filled the vacancy left by Mr. Moore when he resigned as a member of the Board of Directors. The Board of Directors has determined that each of the members of the Audit Committee is independent as defined by the listing standards of the Nasdaq National Market and Section 10A(m)(3) of the Exchange Act. In addition, the Board of Directors has determined that Dr. Gillis is an “audit committee financial expert,” as that term is defined in Item 401(h) of Regulation S-K of the Exchange Act.

Section 16(a) Beneficial Ownership Reporting Compliance

      Section 16(a) of the Exchange Act of 1934, as amended, requires our officers and directors, and persons who own more than 10% of a registered class of our equity securities, to file reports of ownership on Form 3 and changes in ownership on Form 4 or Form 5 with the Securities and Exchange Commission. Such officers, directors and 10% stockholders are also required by the Securities and Exchange Commission rules to furnish us with copies of all Section 16(a) forms they file. Based solely on our review of the copies of such forms we received, we believe that, during the fiscal year ended December 31, 2003, all Section 16(a) filing requirements applicable to our officers, directors and 10% stockholders were satisfied.

Code of Ethics

      On February 18, 2004, the Company adopted a Corporate Code of Ethics for All Employees and Directors. At the same time, the Company adopted a Corporate Code of Ethics for Financial Officers, which specifically applies to the Company’s Chief Executive Officer, Chief Financial Officer and persons performing similar functions. We plan to make each of the codes of ethics available on our website at www.introgen.com. A copy of the full text of each of our codes of ethics may be obtained by any of our stockholders by writing to our Corporate Secretary at Introgen Therapeutics, Inc., 301 Congress Avenue, Suite 1850, Austin, Texas 78701.

      We intend to post on our website any amendment to, or waiver from, a provision of our codes of ethics within five business days following the date of such amendment or waiver.

Board Compensation

      Each non-employee director is granted an option to purchase 33,600 shares of our common stock (exercisable at the fair market value on the date of grant) upon first becoming a director. The option vests ratably each month after the date of grant of such option, so that the entire option is fully vested three years after the date of grant. Each incumbent director is annually granted an option to purchase 20,000 shares of our

common stock (exercisable at the fair market value on the date of grant) on the date of each annual meeting of stockholders. That option vests ratably each month after the date of grant of such option, so that the entire option is fully vested one year after the date of grant. In addition, the chairman of each of the Audit Committee, Compensation Committee and the designated “audit committee financial expert” on the Audit Committee are all granted annually a fully-vested option to purchase 5,000 shares of our common stock. Directors do not receive any cash or other additional compensation, other than reimbursement of their out-of-pocket expenses, for services provided as a director.

Employment Contracts and Change-In-Control Arrangements

      We have an employment agreement with David G. Nance, entered into on August 1, 2003, under which Mr. Nance serves as our President and Chief Executive Officer. Under Mr. Nance’s prior employment agreement with us, which was entered into on August 1, 1996, his base salary was $302,500 per annum effective August 1, 2000, $332,750 per annum effective August 1, 2001, $366,025 per annum effective August 1, 2002. The prior employment agreement provided that Mr. Nance would receive an option to purchase 50,000 shares of our common stock on each of August 1, 2000, August 1, 2001, and August 1, 2002 (for a total of 150,000 shares through August 1, 2002). According to the foregoing terms, he was granted an option to purchase 50,000 shares of our common stock upon the completion of our initial public offering in October 2000; he was granted an option to purchase an additional 50,000 shares of our common stock on August 1, 2001 and he was granted an option to purchase an additional 60,000 shares of our common stock on August 1, 2002. The Compensation Committee granted Mr. Nance the option to purchase 60,000 shares of our common stock on August 1, 2002, rather than an option to purchase 50,000 shares of common stock as required under his employment agreement, due to its decision to discontinue option grants to directors who are also employees. Accordingly, the Compensation Committee granted the 60,000 options to Mr. Nance with the understanding that he would not receive options in his capacity as director.

      The current employment agreement with Mr. Nance, which was entered into on August 1, 2003, continues through July 31, 2006, and thereafter renews automatically for one-year terms until either party gives timely written notice of non-renewal. Mr. Nance’s base salary under the current employment agreement is $476,000 per annum effective August 1, 2003. His compensation under the current employment agreement is subject to review annually. Under the terms of his prior and current employment agreements with us, Mr. Nance may receive bonuses in the form of cash, stock options, restricted stock or other consideration as determined by our Compensation Committee, which reviews his compensation annually. Mr. Nance has also received bonuses from time to time in the form of options to purchase our common stock, as contemplated in each of his prior and current employment agreements with us. Such options are exercisable at a price determined by the administrator of our 2000 Stock Option Plan and are fully vested when granted.

      All of the options granted under our 1995 Stock Plan and the 2000 Stock Option Plan shall immediately vest and become exercisable upon our merger with or into another corporation, entity or person, or the sale of all or substantially all our assets to another corporation, entity or person, unless such options are assumed or an equivalent option or right substituted by the successor corporation or a parent or subsidiary of the successor corporation.

Compensation Committee Interlocks and Insider Participation

      We have a Compensation Committee, which currently consists of directors William H. Cunningham, Ph.D. and Charles E. Long (Chairman). The Compensation Committee administers our 1995 Stock Plan and 2000 Stock Option Plan, reviews compensation to be provided to our officers, employees and consultants, including stock compensation, grants options to purchase our common stock to our employees, executive officers, directors and consultants, and reviews and makes recommendations to the Board of Directors regarding all forms of compensation to be provided to the members of the Board of Directors, including stock compensation.

      None of the members of the Compensation Committee is currently, or has ever been at any time since our formation, one of our officers or employees. No member of the Compensation Committee serves as a member of the board of directors or compensation committee of any entity that has one or more officers serving as a member of our Board of Directors or Compensation Committee.

      David Parker, Ph.D., J.D., our Vice President, Intellectual Property, is a partner with the law firm Fulbright & Jaworski LLP, which provides legal services to us as our primary outside counsel for intellectual property matters.

      We are in negotiations with Dr. Robert Sobol, our Senior Vice President, Medical and Scientific Affairs, to acquire a company of which he is the sole shareholder. The terms of the proposed transaction have not been determined, but the purchase price is likely to be between $1 million and $2 million and to be paid in shares of our common stock. We believe the technology which is owned by Dr. Sobol’s company will be a valuable addition to our intellectual property portfolio. We have endeavored to conduct the negotiations at arms’ length, and any transaction would be subject to the approval of our Audit Committee.
