To Our Clients:

         Enclosed is a Prospectus, dated ________, 2001, of Advanstar
Communications Inc., a New York corporation (the "Company"), and a related
Letter of Transmittal (which together constitute the "Exchange Offer") relating
to the offer by the Company to exchange its 12% Series B Senior Subordinated
Notes due 2011 (the "New Securities"), pursuant to an offering registered under
the Securities Act of 1933, as amended (the "Securities Act"), for a like
principal amount of its issued and outstanding 12% Series A Senior Subordinated
Notes due 2011 (the "Old Securities") upon the terms and subject to the
conditions set forth in the Exchange Offer.

         PLEASE NOTE THAT THE EXCHANGE OFFER WILL EXPIRE AT 5:00 P.M., NEW YORK
CITY TIME, ON ________, 2001 UNLESS EXTENDED.

         The Exchange Offer is not conditioned upon any minimum number of Old
Securities being tendered.

         We are the holder of record and/or participant in the book-entry
transfer facility of Old Securities held by us for your account. A tender of
such Old Securities can be made only by us as the record holder and/or
participant in the book-entry transfer facility and pursuant to your
instructions. The Letter of Transmittal is furnished to you for your information
only and cannot be used by you to tender Old Securities held by us for your
account.

         We request instructions as to whether you wish to tender any or all of
the Old Securities held by us for your account pursuant to the terms and
conditions of the Exchange Offer. We also request that you confirm that we may
on your behalf make the representations contained in the Letter of Transmittal.




         Pursuant to the Letter of Transmittal, each holder of Old Securities
will represent to the Company that (i) the holder is not an "affiliate" of the
Company, (ii) any New Securities to be received by the holder are being acquired
in the ordinary course of its business, and (iii) the holder has no arrangement
or understanding with any person to participate, and is not engaged and does not
intend to engage in a distribution (within the meaning of the Securities Act) of
such New Securities. If the tendering holder is a broker-dealer that will
receive New Securities for its own account in exchange for Old Securities, we
will represent on behalf of such broker-dealer that the Old Securities to be
exchanged for the New Securities were acquired by it as a result of
market-making activities or other trading activities, and acknowledge on behalf
of such broker-dealer that it will deliver a prospectus meeting the requirements
of the Securities Act in connection with any resale of such New Securities. By
acknowledging that it will deliver and by delivering a prospectus meeting the
requirements of the Securities Act in connection with any resale of such New
Securities, such broker-dealer is not deemed to admit that it is an
"underwriter" within the meaning of the Securities Act.


                                    Very truly yours,




                                      2
