                              EMPLOYMENT AGREEMENT
                              --------------------


     THIS EMPLOYMENT AGREEMENT (the "Agreement") is made and entered into as of
June 20, 2001 by and between Advanstar, Inc., a Delaware corporation (the
"Company"), and Joseph Loggia ("Executive"), with effectiveness from the
Effective Date (as defined below in Section 8).

     WHEREAS, the Company currently operates certain trade exposition and
publishing businesses; and

     WHEREAS, the Company wishes to continue to employ Executive and Executive
is prepared to continue to serve in those capacities required by the Company.

     NOW, THEREFORE, the parties agree as follows:

     1.   Position and Authority. The Company agrees to employ the Executive,
          ----------------------
and the Executive accepts such employment and agrees to serve the Company as
President and Chief Operating Officer of the Company, Advanstar Communications
Inc. ("ACI") and any of their respective Subsidiaries as may from time to time
be requested by the Company, for the compensation and benefits detailed in
Sections 3 and 4 hereof. The Executive will report to the Chairman and Chief
Executive Officer of the Company. A "Subsidiary" shall be any company in which
the Company beneficially owns more than 50% of the voting power of such
company's outstanding voting securities.

     2.   Duties and Privileges. Executive shall devote substantially all of his
          ---------------------
business time (subject to four weeks of vacation, or such greater amount as is
authorized by the Board of Directors) to the affairs of the Company during the
employment term, except as may be consented to by the Board of Directors.
Executive shall perform such duties and responsibilities and have such authority
as is consistent with the duties and responsibilities of a President and Chief
Operating Officer, including, without limitation, (a) create the operating plan
(including budget), strategic plan, and related organization for the Company and
ACI and submit such plans for approval by the CEO and the Board of Directors,
(b) implement the approved operating plan, strategic plan and related
organization of the Company and ACI, and (c) such other duties and
responsibilities as the Board of Directors or Chief Executive Officer of the
Company may determine from time to time. All senior management of the Company
and ACI shall report, directly or indirectly as determined by Executive, to
Executive, except for the Company's Chairman, Vice Chairman, Chief Financial
Officer (for his Company duties and responsibilities), and Executive Vice
President - Business Development. Subject to travel requirements from time to
time, Executive will report for work to the Company's offices in the greater Los
Angeles area. Executive will not be required to relocate his permanent residence
outside of greater Los Angeles, California; provided that, if Executive and the
Company agree that Executive will relocate his permanent residence to another
city (a "New Location") and perform his duties and responsibilities pursuant to
the terms of this contract at the Company's offices in the New


                                        1
<PAGE>

Location, then Executive will not be required to relocate his permanent
residence outside the New Location unless Executive and the Company agree.
Executive shall have the right to attend the regular and special meetings of the
Board of Directors as a non-voting observer. Executive shall receive notices of
such meetings at approximately the same time as the members of the Board of
Directors.

     3.   Base Compensation and Bonus.
          ---------------------------

          (a)  Base Compensation. Commencing as of the Effective Date, Executive
               -----------------
will be compensated at a base salary rate of $500,000.00 per year (or such
higher rate as may be set from time to time by the Chief Executive Officer in
his discretion) during the employment term ("Base Salary") Base compensation
will be paid in installments on the same schedule as the Company's Subsidiaries
generally pay their employees. All compensation and benefits will be subject to
reduction by all federal, state, local and other withholdings and similar taxes
and payments required by applicable law.

          (b)  Bonus for any Fiscal Year. Executive shall receive bonus
               -------------------------
compensation based on the relationship between the Company's actual earnings
before interest, taxes, depreciation and amortization and non-cash compensation
expense ("EBITDA") for each fiscal year starting with the fiscal year ending
December 31, 2001 (determined based on the Company's audited financial
statements for such fiscal year) and the EBITDA set for such year in the Company
"Adjusted Business Plan" (as defined below) as follows:

           Actual EBITDA                         Bonus
           as a Percentage                       as a Percentage
           of Plan                               of Base Salary
           -----------------------               --------------
           Less than 80%                         No bonus
           100%                                  50% of Base Salary
           120% or more                          100% of Base Salary


If actual EBITDA as a percentage of the Adjusted Business Plan falls between 80%
and 120%, the amount of bonus shall be pro rated on a straight-line basis. In no
case shall bonus payable under this Section 3(b) exceed 100% of Base Salary
unless agreed to by the Board of Directors in its absolute discretion.

          The "Adjusted Business Plan" shall be the Company's business plan for
the fiscal year in question as approved by the Board of Directors, appropriately
adjusted for acquisitions or dispositions during the year as determined by the
Board of Directors. For greater certainty, the business plan for 2001 (off which
any adjustments for acquisitions and dispositions shall be made) shall be the
business plan for such year approved by the Board in December 2000.

          Any bonus payable under this Section 3(b) shall be paid not later than
90 days after the applicable fiscal year end.


                                        2

     4.   Benefits.
          --------

          (a)  During Executive's employment by the Company, Executive will
receive the same (or substantially similar) employee benefits to those provided
by the Company or its Subsidiaries to other members of senior management from
time to time.

          (b)  During and after the employment term the Company agrees that if
Executive is made a party, or compelled to testify or otherwise participate in,
any action, suit or proceeding (a "Proceeding"), by reason of the fact that he
is or was a director or officer of the Company or any of its Subsidiaries,
Executive shall be indemnified by the Company as provided in Section 145 of the
Delaware General Corporation Law or (but not to any lesser extent) as authorized
by the Company's certificate of incorporation or bylaws or resolutions of the
company's Board of Directors against all cost, expense, liability, damage and
loss reasonably incurred or suffered by Executive in connection therewith, and
such indemnification shall continue as to Executive even if he has ceased to be
a director or officer of the Company or Subsidiary for the period of any
applicable statute of limitations or, if longer, for the period in which any
such Proceeding which commenced within the period of any such statute of
limitations is pending. The Company shall advance to Executive all reasonable
costs and expenses incurred by him in connection with a Proceeding within 20
days after receipt by the Company of a written request for such advance. Such
request shall include an itemized list of the costs and expenses and an
undertaking by Executive to repay the amount of such advance if it shall
ultimately be determined, in a final judgment for which the time to appeal has
expired, that, pursuant to applicable law, he is not entitled to be indemnified
against such costs and expenses.

          (c)  The Company will reimburse Executive for his reasonable and
customary business expenses, including travel, accommodations and meals.

     5.   Stock Options. Subject to the terms, conditions and restrictions
          -------------
(including performance-based vesting) of the 2000 Management Incentive Plan of
Advanstar Holdings Corp. ("Parent"), and the option agreement with respect
                           ------
thereto, the Company will grant the Executive an option to purchase up to
400,000 shares of Parent's Common Stock at $10.00 per share.

     6.   Term. This Agreement shall have a term equal to the period from the
          ----
Effective Date through December 31, 2003 (the "Employment Term"), provided that
                                                                  --------
Sections 9 and 10 shall survive such expiration in accordance with their terms.
In addition, in the event that this Agreement is not renewed (or replaced by a
new agreement) after such expiration, Executive's employment with the Company
shall continue on no less favorable terms to Executive until terminated in
accordance with Section 7, which shall survive such expiration.

     7.   Termination.
          -----------

          (a)  This Agreement may be terminated by the Company at any time for
Cause upon written notice to Executive, which notice shall specify the reason
for termination. Such notice shall be given at any time prior to termination in
the case of matters described in clauses (B) or (C), and shall be given not less
than 30 days prior to the date of termination, in the case of matters described
in clauses (A), (D) or (E), and in the case of matters described in clauses (A),
(D) or (E) shall be rescinded if the Executive cures any misconduct, negligent
act, breach or failure giving rise to such notice to the reasonable satisfaction
of the Board of Directors, including curing any damage suffered by the Company
as a result thereof. As used herein, "Cause" shall mean (A) willful misconduct
or gross negligence by Executive in respect of his material obligations under
this Agreement, (B) conviction of a felony involving moral turpitude, (C) theft
of Company property or other disloyal or dishonest conduct of the Executive that
materially harms the Company or its business or (in the case of dishonest
conduct) undermines the confidence of the Board or the Chief Executive Officer
in the Executive, (D) willful breach of this Agreement, or (E) willful failure
to observe Company policies or carry out the directives of the Board of
Directors or the Chief Executive Officer of the Company consistent with the
terms of this Agreement.

          (b)  Executive may terminate this Agreement for Good Reason by giving
sixty (60) days prior written notice to the Company specifying such Good Reason;
provided that the Company has not cured the condition giving rise to the
--------
Executive's right to terminate this Agreement pursuant to this Section 7(b)
within 30 days of the Company's receipt of the written notice in accordance with
this Section 7(b). "Good Reason" shall exist only if (i) Executive is removed or
is not re-appointed as President and Chief Operating Officer, except in
connection with termination of this Agreement by the Company for Cause or due to
death or Disability (as defined below) or (ii) breach by the Company of any
material obligation of the Company under this Agreement. Executive may terminate
this Agreement without Good Reason by giving sixty (60) days prior written
notice to the Company.

          (c)  Should the Executive terminate this Agreement for Good Reason, or
should the Company terminate this Agreement without Cause, then the Executive
shall be entitled to receive such bonus payable under Section 3(b) hereof,
provided that any bonus under Section 3(b) will be payable only with respect to
--------
that portion of the fiscal year in which Executive's employment was terminated
(or any prior fiscal year for which bonus remains unpaid)); bonus for any
partial fiscal year shall be determined by multiplying the bonus Executive would
have received had he continued to work for the Company during the entire fiscal
year by a fraction, the numerator of which is the number of days in the fiscal
year during which Executive was employed by the Company, and the denominator of
which is 365 (such amount the "Pro Rata Bonus Amount").

          (d)  This Agreement shall terminate automatically upon Executive's
death. This Agreement may be terminated by the Company upon written notice to
Executive, or by Executive upon written notice to the Company, upon Executive's
Disability. For purposes of this Agreement, "Disability" means the Executive's
suffering of a disability which shall have prevented him from performing his
obligations hereunder for a period of at least 90 consecutive

                                        4
<PAGE>

days or 120 non-consecutive days in any 365 day period. In the event of
termination of this Agreement due to Executive's death or Disability, in
addition to any salary due to Executive as of the date of death or Disability
and remaining unpaid, Executive shall be entitled to receive, at such time as
Executive would otherwise would have received such sum, the Pro Rata Bonus
Amount for the portion of the fiscal year in which Executive's death or
Disability occurred during which Executive was employed by the Company.

          (e)  If the Company terminates this Agreement with Cause or if the
Executive terminates this Agreement without Good Reason, or if this Agreement is
terminated under clause (d) above, then the Executive shall, from the date of
such termination, no longer be entitled to any compensation or any bonus under
Sections 3 or 4 (other than, (i) in the case of termination for Disability,
disability benefits as provided pursuant to Section 4; (ii) in the case of
termination for death or Disability, any bonus payable pursuant to clause (d)
above; and (iii) in the case of the Executive terminating without Good Reason,
as provided in the letter agreement referenced in Section 9). Nothing in this
clause (e) shall affect Executive's rights under Company health and disability
plans in which Executive participates to the extent such plans provide for
benefits to be paid following the termination of employment.

          (f)  Termination of this Agreement shall not discharge any liability
(of either the Company or the Executive) existing at the date of termination.
Further, notwithholding any termination, the provisions of Sections 9 and 10
shall survive in accordance with their terms.

     8.   Effective Date. This Agreement shall take effect as of June 20, 2001
          --------------
(the "Effective Date").


     9.   Non-Competition and Confidentiality. Executive shall execute and
          -----------------------------------
deliver a letter agreement in the form of Exhibit A hereto.

     10.  Arbitration. Any claim arising out of or relating to this Agreement
          -----------
(including disputes regarding the presence or absence of "Cause" or "Good
Reason" in the event of a termination), or otherwise arising out of or relating
to the Executive's employment by the Company, will be subject to arbitration in
New York, New York, in accordance with the Federal Arbitration Act and the rules
of the American Arbitration Association relating to commercial disputes. The
prevailing party in any such arbitration shall be entitled to recover from the
other party its reasonable expenses incurred in connection with such
arbitration, including the reasonable fees and expenses of counsel.

     11.  Severability. If any provision of this Agreement is determined to be
          ------------
invalid or unenforceable, it shall be adjusted rather than voided, to achieve
the intent of the parties to the extent possible, and the remainder of the
Agreement shall be enforced to the maximum extent possible.

     12.  Entire Agreement. This Agreement (along with the letter agreement
          ----------------
referenced in Section 9) constitutes the entire agreement between Executive and
the Company with respect to the terms and conditions of the employment of
Executive by the Company, and supersedes all

                                        5
<PAGE>

prior or concurrent arrangements, discussions, agreements or understandings with
respect to your employment.

     13.  Governing Law. This Agreement shall be governed by the laws of the
          -------------
state in which Executive has his principal residence at the time an enforcement
action is initiated without regard to principles of conflicts of law.

     14.  Notice. Any notice, or other written communication to be given
          ------
pursuant to this Agreement for whatever reason shall be deemed duly given and

Dear Mr. Loggia:

     You are to be employed by Advanstar, Inc. (the "Company" and, together with
its subsidiaries "Advanstar") pursuant to an Employment Agreement of even date
herewith (the "Employment Agreement"). In consideration of your employment with
the Company, you and the Company agree as follows:

     1.   Non-Competition. You agree that you will not, during the course of
          ---------------
your employment with the Company or for the one year period following the
termination of such employment (the "Non-Compete Period"), compete with
Advanstar, as defined in paragraph 4 below. If there is any conflict between the
provisions of this letter agreement and the provisions of any other agreement
between you and the Company in respect of the subject matter hereof, the
provisions of this agreement shall govern.

     2.   Confidentiality. You acknowledge that your association with Advanstar
          ---------------
will bring you into close contact with many confidential affairs of Advanstar,
including information about costs, profits, markets, sales, publications, key
personnel, pricing policies, operational methods, other business affairs,
methods and other information not readily available to the public, and plans for
future development. In recognition of the foregoing, you covenant and agree that
you will keep confidential all material confidential to Advanstar that is not
otherwise in the public domain and that you will not intentionally disclose any
such information to anyone outside Advanstar or make any use thereof for your
own benefit or for any purpose other than the advancement of the business of
Advanstar at any time except with the prior written consent of Advanstar as
evidenced by a certified resolution of the Chief Executive Officer or the Board
of Directors of the Company. For purposes of this Agreement, the following
information shall be deemed not to constitute confidential information of
Advanstar:

          (a)  Any information developed independently by you;


                                        7
<PAGE>

          (b)  Information that was received by you from a third-party, which,
               to your knowledge, is not bound by an agreement of
               confidentiality with Advanstar; or

          (c)  Any information that is in the public domain or generally
               available to the public.

     3.   No Solicitation of Employees. You covenant that, for the duration of
          ----------------------------
the Non-Compete Period, you will not, and no person, corporation, partnership,
or other entity over which you exercise control (whether as an officer,
director, sole proprietor, holder, debt or equity securities, consultant,
partner, or otherwise) will, directly or indirectly (a) enter into any written
or oral agreement or understanding relating to the services of any person who is
then employed by Advanstar or, in the case of any employee other than
secretaries, clerks and similar employees fulfilling merely clerical functions,
who has been so employed within the preceding six months, or (b) solicit, or bid
against Advanstar in an attempt to be awarded, any trade show or exposition
business, or any publishing contract, from any party sponsoring or arranging any
trade show or exposition, or publishing or sponsoring any publication, in either
case with which Advanstar then has such a relationship or contract. If there is
any conflict between the provisions of this letter agreement and the provisions
of any other agreement between you and the Company in respect of the subject
matter hereof, the provisions of this agreement shall govern.

     4.   Certain Definitions. For purposes of this Letter Agreement,
          -------------------
competition with Advanstar shall include carrying on any business that is
competitive with the business of Advanstar's Fashion Group of trade exhibitions
(including without limitation, MAGIC International, WWD MAGIC, MAGIC Kids, the
Edge and the former Larkin events). Nothing in this Letter Agreement shall
prohibit you from being a passive owner of not more than 2% of the outstanding
stock of any class or a corporation which is publicly traded, so long as you
have no active participation in the management or business of such corporation.

     5.   Consideration. As consideration for the continued fulfillment of your
          -------------
covenants under this Letter Agreement, you shall be entitled to continue during
the Non-Compete Period to receive (in the normal bi-weekly course in accordance
with the Company's standard payroll practices) your base salary as provided in
Section 3(a) of the Employment Agreement; provided that (a) no such payments
shall be due to you or made by the Company if your employment was terminated (i)
by the Company for Cause (as defined in Section 7(a) of the Employment
Agreement) or (ii) due to your death or Disability (as defined in Section 7(d)
of the Employment Agreement); and (b) your entitlement to receive such payments
and the Company's obligation to make such payments shall cease upon your failure
to comply with any of your covenants under this Letter Agreement; provided that
in the case of clause (b) the Company shall give you written notice describing
such failure not less than ten business days prior to the proposed date of
cessation of payments, and such notice shall be rescinded (and the payments
shall not cease) if you reasonably cure such failure prior to the conclusion of
the notice period. The termination of the payment obligation pursuant to clause
(a) or (b) of the foregoing sentence shall not release you from your covenants
under this Letter Agreement.


                                        8
<PAGE>

     6.   Severability. The scope and effect of the terms and provisions
          ------------
contained in this Letter Agreement (including the noncompetition covenant
contained in Section 1) will be as broad in time (but not beyond the time
periods specified herein), geography, and all other respects as is permitted by
applicable law. If arbitrators, a court, or another body of competent
jurisdiction determine that any term or provision of this Agreement is excessive
in scope, then if possible such term or provision will be adjusted (rather than
voided) in accordance with the purpose stated in the preceding sentence and with
applicable law, but in such a manner as to minimize the change in the provision.
If such term or provision cannot be so adjusted, then it will be struck. All
other terms and provisions of this Letter Agreement will be deemed valid and
enforceable to the full extent possible. The provisions of Section 5(b) shall
continue to remain applicable (based on compliance with the terms of this Letter
Agreement) regardless of whether any such terms are adjusted or struck in regard
to legal enforceability.

     7.   Remedies. If any of the covenants or agreements in Sections 1, 2 or 3
          --------
are violated or threatened to be violated, you agree and acknowledge that such
violation or threatened violation will cause irreparable injury to Advanstar,
and that the remedy at law of Advanstar for any such violation or threatened
violation will be inadequate and that Advanstar will be entitled to obtain any
injunction prohibiting a continuance or occurrence of such violations or
threatened violations in addition to (not in limitation of) any other rights or
remedies available at law or in equity. Your services hereunder are of a
special, unique, unusual, extraordinary character which gives them peculiar
value, the loss of which cannot be reasonably or adequately computed in damages.

     The provisions of this Letter Agreement will be binding upon and inure to
the benefit of our respective heirs, executives, administrators, successors and
assigns. This Letter Agreement will be governed by and construed in accordance
with the laws of the state in which you have your principal residence at the
time an enforcement action is initiated without regard to principles of
conflicts of law.

                                     Very truly yours,

                                     ADVANSTAR, INC.
