NEW YORK -- In the release dated April 19, 2007, the dates indicated in the fourth graph should read: May 2, 2007 (sted May 3, 2007).

The corrected release reads: ADVANSTAR, INC. AND ADVANSTAR COMMUNICATIONS INC. ANNOUNCE TENDER OFFERS AND CONSENT SOLICITATIONS FOR 10 3/4% SECOND PRIORITY SENIOR SECURED NOTES, 12% SENIOR SUBORDINATED NOTES AND 15.0% SENIOR DISCOUNT DEBENTURES

Advanstar, Inc. ("Advanstar") and Advanstar Communications Inc. ("Communications" and together with Advanstar, the "Issuers") today announced that they have commenced a cash tender offer for Communications' 10 3/4% Second Priority Senior Secured Notes due 2010 (CUSIP Nos. 00758RAM6 and 00758RAH7) (the "Senior Secured Notes") and 12% Senior Subordinated Notes due 2011 (CUSIP No. 00758RAF1) (the "Senior Subordinated Notes") and Advanstar's 15.0% Senior Discount Debentures due 2011 (CUSIP No. 00759JAE1) (the "Debentures", and, together with the Senior Secured Notes and the Senior Subordinated Notes, the "Notes"). Pursuant to the terms and conditions of the offers, Communications will purchase any and all of its Senior Secured Notes and Senior Subordinated Notes and Advanstar will purchase any and all of its Debentures. Advanstar and Communications are also soliciting consents to proposed amendments to the indentures governing each of the Notes that would eliminate substantially all of the restrictive covenants and eliminate or modify certain default provisions in the indentures. The proposed amendments to the indenture governing the Senior Secured Notes would also release the security interest in the collateral under that indenture and related security documents. The tender offer will expire at 5 p.m., New York City time, on May 18, 2007, unless extended or terminated (the "Expiration Date").

The tender offers and consent solicitations are being conducted in connection with the previously announced pending acquisition of all of the outstanding stock of Advanstar Holdings Corp., the holding company for Advanstar and Communications, by an investor group led by Veronis Suhler Stevenson (the "Acquisition Transaction"). The consummation of the tender offers is conditioned upon, and is expected to occur simultaneously with, the closing of the Acquisition Transaction, but satisfactory completion of the tender offers is not a condition to closing of the Acquisition Transaction. The Expiration Date will be extended to coincide with closing of the Acquisition Transaction, which is not expected to close before May 31, 2007.

The tender offers and consent solicitations are being made solely pursuant to an Offer to Purchase and Consent Solicitation Statement dated April 19, 2007 (the "Statement") and the related Consent and Letter of Transmittal, which include a more comprehensive description of the terms and conditions thereof.

Subject to the terms and conditions of the tender offers, the purchase price for each $1,000 principal amount outstanding of Senior Secured Notes validly tendered and accepted for purchase by Communications will be the price calculated from the yield to maturity on the applicable reference United States Treasury, as of 10:00 a.m., New York City time, on May 2, 2007 plus a fixed spread of 0.50% less the consent payment referred to below. The purchase price for each $1,000 principal amount outstanding of Senior Subordinated Notes validly tendered and accepted for purchase by Communications will be $1,013.50 and the purchase price for each $1,000 principal amount outstanding of Debentures validly tendered and accepted for purchase by Advanstar will be $1,012.50. Holders who tender their Notes and deliver their consents prior to 5:00 p.m., New York City time, on May 2, 2007 (as such date may be extended, the "Consent Date") will also receive a consent payment of $30.00 per $1,000 outstanding principal amount of Notes tendered and accepted in the offers. Holders whose Notes are accepted for purchase in the tender offers will also receive accrued and unpaid interest to, but not including, the settlement date for the tender offers.

The principal purpose of the tender offers and the consent solicitations is to acquire the outstanding Notes and eliminate substantially all of the restrictive and reporting covenants, eliminate or modify certain events of default and certain other related provisions contained in the indentures with respect to the Notes so that any non-tendered Notes do not restrict the future financial and operating flexibility of Advanstar and Communications. The proposed amendments to the indenture governing the Senior Secured Notes would also release the security interest in the collateral under that indenture and related security documents. The tender offers and consent solicitations are conditioned upon certain general conditions described in the Statement. The proposed amendments to an indenture governing a series of Notes will only become operative if the holders of at least a majority of the aggregate principal amount of such series of Notes validly consent to such amendments. Certain of the proposed amendments to the indentures governing the Senior Secured Notes and the Debentures will not become operative unless the consent of holders of at least two-thirds of the outstanding aggregate principal amount of such Notes are received.

Holders who desire to tender their Notes must consent to all the proposed amendments and may not deliver a consent without tendering their Notes. Any Notes tendered before the Consent Date may be withdrawn at any time on or prior to the Consent Date, but not thereafter, except as required by law. Any Notes tendered after the Consent Date may not be withdrawn, except as may be required by law. While the Issuers will extend the Expiration Date until the date of the closing of the Acquisition Transaction, they do not expect to extend withdrawal rights beyond the Consent Date.
