NEW YORK -- Advanstar, Inc. ("Advanstar") and Advanstar Communications Inc. ("Communications" and together with Advanstar, the "Issuers") announced as of 5:00 p.m., New York City time, today (the "Consent Date"), that Communications has received consents from holders of approximately 100% of its outstanding 10 3/4% Second Priority Senior Secured Notes due 2010 (CUSIP Nos. 00758RAM6 and 00758RAH7) (the "Senior Secured Notes") and 93.41% of its 12% Senior Subordinated Notes due 2011 (CUSIP No. 00758RAF1) (the "Senior Subordinated Notes") and that Advanstar has received 97.96% of its 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"). The consents are sufficient to effect all of the proposed amendments to the indentures governing each of the Notes as set forth in the Issuers' Offer to Purchase and Consent Solicitation Statement dated April 19, 2007 (the "Statement") and the related Consent and Letter of Transmittal, pursuant to which the tender offers and the consent solicitations are being made. The proposed amendments 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 also release the security interest in the collateral under that indenture and related security documents.

The tender offers and consent solicitations will expire at 5:00 p.m., New York City time, on May 18, 2007, unless extended. As previously announced, the Issuers intend to extend the Expiration Date until closing of the previously announced acquisition of the Issuers, which is expected to occur on or about May 31, 2007. The purchase price, assuming a settlement date of May 31, 2007, for each $1,000 principal amount outstanding of Senior Secured Notes is $1,057.53, 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, today, 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 is $1,013.50, and the purchase price for each $1,000 principal amount outstanding of Debentures is $1,012.50.

Holders who tendered their Notes and delivered their consents on or prior to the Consent Date will, in addition to the purchase price, receive a consent payment of $30 per $1,000 outstanding principal amount of Notes tendered and accepted in the tender 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.

Notes tendered and not validly withdrawn prior to the Consent Date may not be withdrawn except as may be required by law. Notes tendered after the Consent Date may not be withdrawn, except as may be required by law.

The Issuers will proceed to execute supplemental indentures effecting the proposed amendments to the indentures governing each series of Notes. The supplemental indentures will become operative only if the Issuers accept the Notes for payment pursuant to the terms of the tender offers. When the supplemental indentures become operative, they will be binding on the holders of Notes not purchased in the tender offers.

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