Advanstar Announces Receipt of Consents from Holders of over 88.75% of Second Priority Senior Secured Floating Rate Notes Due 2008 and Payment of Total Consideration to All Holders Whose Tenders Are Accepted in the Tender Offer and Consent Solicitation.

NEW YORK -- Advanstar Communications Inc. ("Advanstar") announced that as of 5:00 p.m., New York City time, today (the "Consent Date") it has received consents from holders of approximately 88.75% of its outstanding Second Priority Senior Secured Floating Rate Notes due 2008 (CUSIP No. 00758RAL8) (the "Floating Rate Notes"). The consents are sufficient to effect all of the proposed amendments to the indenture governing the Floating Rate Notes as set forth in Advanstar's Offer to Purchase and Consent Solicitation Statement dated May 31, 2005 (the "Statement") and the related Consent and Letter of Transmittal, pursuant to which the tender offer and the consent solicitation are being made. The proposed amendments eliminate, with respect to the Floating Rate Notes only, substantially all of the restrictive covenants and certain default provisions in the indenture governing the Floating Rate Notes. The proposed amendments also release the security interest in the collateral under the indenture and security documents with respect to the Floating Rate Notes.

Advanstar also announced that, subject to the terms and conditions of the tender offer and consent solicitation, it will pay the total consideration, including the consent payment, to each holder who validly tenders Floating Rate Notes on or prior to 5:00 p.m., New York City time, on June 28, 2005, the currently scheduled expiration date for the tender offer and consent solicitation, provided such holder's Floating Rate Notes are accepted in the tender offer. The total consideration for the tender offer and consent solicitation is $1,073 for each $1,000 principal amount outstanding of Floating Rate Notes, which includes a $30 consent payment. Holders should note that, as a result of principal amortization, while each Floating Rate Note was issued in a face amount of $1,000, the outstanding principal amount of each Floating Rate Note is currently $982.50. Accordingly, a holder will not receive $1,073 as the total consideration in respect of each such Floating Rate Note, but rather an amount equal to 107.3% of the actual outstanding principal amount of such Note. Holders whose Floating Rate Notes are accepted for purchase in the tender offer will also receive accrued and unpaid interest to, but not including, the settlement date for the tender offer.

Floating Rate Notes tendered and not validly withdrawn prior to the Consent Date may not be withdrawn except as may be required by law. Floating Rate Notes tendered after the Consent Date may not be withdrawn, except as may be required by law.

Advanstar will proceed to execute a supplemental indenture effecting the proposed amendments to the indenture. The supplemental indenture will become operative only if Advanstar accepts the Floating Rate Notes for payment pursuant to the terms of the tender offer. When the supplemental indenture becomes operative, it will be binding on the holders of Floating Rate Notes not purchased in the tender offer.

The closing of the tender offer is subject to certain conditions set forth in the Statement.
