ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS

        Advanstar Communications Inc. (the "Company") is a New York Corporation. Section 402(b) of the New York Business Corporation ("NYBCL") statute generally provides that a company's certificate of incorporation may set forth a provision eliminating or limiting the personal liability of its directors for damages for any breach of duty in such capacity, provided that no such provision shall eliminate or limit the liability of any director if a judgment or other final adjudication adverse to him establishes (i) that his acts or omissions were in bad faith or involved intentional misconduct or a knowing violation of law; or (ii) that he personally gained in fact a financial profit or other advantage to which he was not legally entitled; or (iii) that his acts violated section 719 of the NYBCL.

        In addition, section 722(a) of the NYBCL generally provides that a corporation may indemnify officers made, or threatened to be made, a party to an action or proceeding, other than one by or in the right of the corporation to procure a judgment in its favor, including an action by or in the right of any other corporation, or other enterprise, which any director or officer of the corporation served in any capacity at the request of the corporation, by reason of the fact that he was a director or officer of the corporation, or served such other corporation, or other enterprise in any capacity, against judgments, fines, amounts paid in settlement and reasonable expenses, including attorneys fees, if such director or officer acted in good faith.

        Section 722(c), in general, further provides that a corporation may indemnify any person made, or threatened to be made, a party to an action by or in the right of the corporation to procure a judgment in its favor by reason of the fact that he is or was a director or officer of the corporation, or is or was serving at the request of the corporation as a director or officer of any other corporation, or other enterprise, against amounts paid in settlement and reasonable expenses, including attorneys fees in connection with the defense or settlement of such action if such director or officer acted in good faith.

        Generally, the Company's certificate of incorporation eliminates the personal liability of its directors to the fullest extent permitted by the provisions of paragraph (b) of section 402 of the NYBCL. In addition, the Company's bylaws indemnify its directors and officers in connection with any

II-1

proceeding, including an action by or in the right of the corporation, by reason of the fact that such person is or was a director or officer of the Company, or is or was serving at the request of the Company as a director, officer, trustee, employee or agent of another corporation or other enterprise, except in relation to matters as to which a director or officer is adjudged to have breached his duty of care or to have acted in bad faith.

ITEM 17. UNDERTAKINGS

        (a) The undersigned hereby undertakes:

(1)

To file during any period in which offers or sales are being made, a post-effective amendment to this registration statement:



(i)

to include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;



(ii)

to reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in the volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20 percent change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration statement; and



(iii)

to include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;



(2)

That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

II-6

(3)

To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.



(b)

Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to our directors, officers and controlling persons pursuant to the foregoing provisions, or otherwise, we have been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by us of expenses incurred or paid by one of our directors, officers or controlling persons in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, we will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.
