                              EMPLOYMENT AGREEMENT


              THIS EMPLOYMENT AGREEMENT is made on August 7, 1998,1998
between Penton Media, Inc., a Delaware corporation (the "COMPANY"), and William
C. Donohue ("EXECUTIVE").

              This Employment Agreement is entered into as a condition precedent
to the consummation of the transactions contemplated in a Combination Agreement
dated as of May 21, 1998 by and among the Company, Executive and other parties
(the "COMBINATION AGREEMENT"). Pursuant to the Combination Agreement, Donohue
Meehan Publishing Company, an Illinois corporation, is being merged with and
into D-M Acquisition Corp., an Illinois corporation wholly-owned by the Company
that is changing its name to Donohue Meehan Publishing Company in connection
with the merger. The corporation surviving the merger as Donohue Meehan
Publishing Company is referred to herein as "D.M. PUB."; the original Donohue
Meehan Publishing Company is referred to herein as "D.M. PUB.'S PREDECESSOR".

              In consideration of the mutual covenants contained herein and
other good and valuable consideration, the receipt and sufficiency of which are
hereby acknowledged, the parties hereto agree as follows:

              1. EMPLOYMENT. The Company shall employ Executive, and Executive
accepts employment with the Company, upon the terms and conditions set forth in
this Agreement, for the period beginning at the Effective Time (as defined in
the Combination Agreement) and ending on the second anniversary of the Effective
Time (the "EMPLOYMENT PERIOD").

               2. POSITION AND DUTIES.

              (a) During the Employment Period, Executive shall serve as the
President of D.M. Pub., and shall have the normal duties, responsibilities and
authority of an executive serving in such position, under the direction of the
Board of Directors of the Company (the "BOARD"), the Chief Executive Officer and
the Chief Operating Officer of the Company and the Board of Directors of D.M.
Pub.

              (b) Until the Company's 2000 annual meeting of stockholders,
Executive shall serve as a director of the Company.

              (c) Executive shall report to the Chief Operating Officer of the
Company.

              (d) During the Employment Period, Executive shall devote his full
business time and attention (except for permitted vacation periods, reasonable
periods of illness or other incapacity and, provided such activities do not
exceed those in which Executive has engaged in the past while serving as the
President of D.M. Pub.'s predecessor, participation in charitable and civic
endeavors and management of Executive's personal investments and business
interests) to the business and affairs of D.M. Pub.; provided that the Company
may require Executive to devote up to 10% of his





<PAGE>   2



business time to the business and affairs of the Company and its other
subsidiaries and affiliates. Executive shall perform his duties and
responsibilities to the best of his abilities in a diligent, trustworthy,
businesslike and efficient manner.

              (e) Executive shall be based at a location in, and shall perform
his duties and responsibilities principally in, the Chicago metropolitan area,
and shall not be required to travel outside that area significantly more
extensively than he has done in the past in the ordinary course of the business
of D.M. Pub.'s predecessor.

              (f) Nothing contained in this Paragraph 2 shall constitute a
waiver by either the Company or Executive of any of the provisions of Section
2.4 (g)(iv) of the Combination Agreement.

              3.     COMPENSATION AND BENEFITS.

              (a) SALARY. The Company agrees to pay Executive a salary during
the Employment Period, in semimonthly installments. Executive's salary shall be
$250,000 per annum.

              (b) BONUS. If, based on the final determinations of the Surviving
Corporation's Pre- Tax Profits for 1998 and 1999 pursuant to Section 2.4 of the
Combination Agreement, the total Contingent Cash Payments which the D-M
Shareholders, in the aggregate, would have become entitled to receive pursuant
to Section 2.4(g)(i) of the Combination Agreement would have exceeded $4.0
million had there been no $4.0 million limitation on the total amount of such
Contingent Cash Payments, the Company shall pay to Executive, on the date on
which the Employment Period is scheduled to end, an amount equal to (x) one-half
of such excess divided by (y) four and one-half. Notwithstanding the foregoing:
(i) the amount of the bonus shall not exceed $114,000 and (ii) if any event
described in clause (B) of the final sentence of Section 2.4(g)(i) of the
Combination Agreement occurs, the amount of the bonus shall be $114,000. (Thus,
for example, if the total amount of Contingent Cash Payments which the D-M
Shareholders, in the aggregate, become entitled to receive is less than $4.0
million, the amount of the bonus will be zero dollars, and if the total amount
of Contingent Cash Payments which the D-M Shareholders, in the aggregate, become
entitled to receive is $4.0 million but such total amount would have been $5.026
million but for the $4.0 million limitation, the amount of the bonus will be
$114,000). For purposes of this Agreement, any bonus will be deemed earned on
(but not until) the date on which the Employment Period is scheduled to end.

              (c) EXPENSE REIMBURSEMENT. The Company shall reimburse Executive
for all reasonable expenses incurred by him in the course of performing his
duties under this Agreement which are consistent with the Company's policies in
effect from time to time with respect to travel, entertainment and other
business expenses, subject to the Company's requirements applicable generally
with respect to reporting and documentation of such expenses.

              (d) STANDARD BENEFITS PACKAGE. In addition to the salary and any
bonus earned, Executive shall be entitled during the Employment Period to
participate in the Company's standard benefits package in effect from time to
time, on the same basis (including sharing of costs) as other



                                       2

<PAGE>   3



executives of the Company having principal responsibility for magazines
comparable in profit contribution to those for which Executive has principal
responsibility; provided that (i) any awards made to Executive under the Penton
1998 Stock Awards Plan (as defined in the Combination Agreement) prior to
January 1, 2000 (or, if earlier, the occurrence of any event described in clause
(B) of the final sentence of Section 2.4(g)(i) of the Combination Agreement)
shall be limited to non-qualified options and (ii) Executive shall be entitled
to vacation at the rate of four weeks per calendar year. In order to be provided
such employee benefits (other than vacation), Executive shall satisfy such
requirements for eligibility and coverage as may be in force from time to time
during the Employment Period taking into account the provisions of the second
sentence of Section 7.8(i) of the Combination Agreement.

              4.    TERMINATION.

              (a) Notwithstanding Paragraph 1 hereof, the Employment Period
shall end early upon the first to occur of any of the following events:

                    (i)    Executive's death;

                    (ii)   the Company's termination of Executive's employment
                           on account of Executive's having become unable (as
                           determined by the Board in good faith) to regularly
                           perform his duties hereunder by reason of illness or
                           incapacity for a period of more than six (6)
                           consecutive months ("TERMINATION FOR DISABILITY");

                    (iii)  the Company's termination of Executive's employment
                           for Cause ("TERMINATION FOR CAUSE");

                    (iv)   the Company's termination of Executive's employment
                           other than a Termination for Disability or a
                           Termination for Cause ("TERMINATION WITHOUT CAUSE");
                           or

                    (v)    Executive's termination of Executive's employment for
                           Good Reason, by means of written notice to the
                           Company identifying such termination as a Termination
                           by Executive for Good Reason ("TERMINATION BY
                           EXECUTIVE FOR GOOD REASON").

              (b) For purposes of this Agreement, "CAUSE" shall mean:

                    (i)    the commission by Executive of a felony;

                    (ii)   the commission by Executive of any act involving
                           fraud or dishonesty with respect to the Company or
                           any of its subsidiaries or affiliates which causes
                           harm or damage material to them as a whole;




                                       3

<PAGE>   4



                    (iii)  gross negligence or willful misconduct by Executive
                           related to his duties and responsibilities hereunder
                           which causes harm or damage material to the Company
                           and its subsidiaries and affiliates as a whole;

                    (iv)   repudiation of this Agreement by Executive or
                           Executive's abandonment of his employment with the
                           Company (it being expressly understood that a
                           Termination by Executive for Good Reason shall not
                           constitute such repudiation or abandonment);

                    (v)    breach by Executive of any of the agreements in
                           Paragraph 7 hereof; or

                    (vi)   any other breach by Executive of this Agreement which
                           is material and which is not cured within thirty (30)
                           days after written notice thereof to Executive from
                           the Company.

              (c) For purposes of this Agreement, "GOOD REASON" shall mean any
breach by the Company of this Agreement which is material and which is not cured
within thirty (30) days after written notice thereof to the Company from
Executive.

              5.    POST-EMPLOYMENT PERIOD PAYMENTS.

              (a) If the Employment Period ends on the date on which it is
scheduled to end, or if the Employment Period ends early for any reason,
Executive shall thereafter be entitled to (and only to):

                    (i)    any salary or bonus which has been earned but is
                           unpaid, any reimbursable expenses which have been
                           incurred but are unpaid, and any vacation days which
                           have accrued but are unused and unexpired under the
                           Company's vacation policy, as of the end of the
                           Employment Period;

                    (ii)   any plan benefits which by their terms extend beyond
                           termination of Executive's employment;

                    (iii)  any benefits to which Executive is entitled under the
                           Consolidated Omnibus Budget Reconciliation Act of
                           1985, as amended ("COBRA"); and

                    (iv)   any other amount(s) payable pursuant to the
                           succeeding provisions of this Paragraph 5.

                    (b) In the event of Executive's death during the Employment
Period, the Company shall pay to Executive's estate (or such person or persons
as Executive may designate in a written instrument signed by him) amounts equal
to the amounts Executive would have received as salary and bonus had the
Employment Period remained in effect until the date on which it was scheduled to
end, at the times such amounts would have been paid.




                                       4

<PAGE>   5



                    (c) If the Employment Period ends early on account of
Termination for Cause: (i) the Company shall pay Executive an amount equal to
that Executive would have received as salary had the Employment Period remained
in effect until the later of the effective date of the Company's termination of
Executive's employment or the date thirty days after the Company's notice to
Executive of such termination; and (ii) the Company shall pay to Executive an
amount equal to any amount Executive would have received as bonus had the
Employment Period remained in effect until the date on which it was scheduled to
end, reduced to the fraction thereof of which the numerator is the number of
days during the Employment Period which have elapsed as of the end of the
Employment Period and the denominator is 731, at the time such amount would have
been paid.

                    (d) If the Employment Period ends early on account of a
Termination without Cause or a Termination by Executive for Good Reason, the
Company: (i) shall pay to Executive amounts equal to the amounts Executive would
have received as salary and bonus had the Employment Period remained in effect
until the date on which it was scheduled to end, at the times such amounts would
have been paid, less payments, if any, to which Executive is entitled during the
payment period under any disability benefit plan or the like in which Executive
has participated as an employee of the Company; and (ii) shall permit Executive
to participate, until the date on which the Employment Period was scheduled to
end, in any medical, dental and life insurance programs included in the
Company's standard benefits package in effect from time to time, on the same
basis (including sharing of costs) as other executives of the Company having
principal responsibility for magazines comparable in profit contribution to
those for which Executive had principal responsibility at the end of the
Employment Period, in the case of each of such programs to the extent
participation by a former employee is permitted by the terms thereof. It is
expressly understood that the Company's payment obligations under this (d) shall
cease in the event Executive breaches any of his agreements in Paragraph 6 or 7
hereof.

                    6. CONFIDENTIAL INFORMATION. Executive acknowledges that the
information, observations and data obtained by him while employed by the Company
pursuant to this Agreement, as well as those obtained by him while employed by
D.M. Pub.'s predecessor prior to the date of this Agreement, concerning the
business or affairs of the Company or any of its subsidiaries or affiliates or
any predecessor thereof (unless and except to the extent the foregoing become
generally known to and available for use by the public other than as a result of
Executive's acts or omissions to act, "CONFIDENTIAL INFORMATION") are the
property of the Company or such subsidiary or affiliate. Therefore, Executive
agrees that during the Employment Period and for three years thereafter he shall
not disclose any Confidential Information without the prior written consent of
the Chief Executive Officer of the Company unless and except to the extent that
such disclosure is (i) made in the ordinary course of Executive's performance of
his duties under this Agreement or (ii) required by any subpoena or other legal
process (in which event Executive will give the Company prompt notice of such
subpoena or other legal process in order to permit the Company to seek
appropriate protective orders), and that he shall not use any Confidential
Information for his own account without the prior written consent of the Chief
Executive Officer of the Company. Executive shall deliver to the Company at the
termination of the Employment Period, or at any other time the Company may
reasonably request, all memoranda, notes, plans, records, reports, computer
tapes and software and other documents and data (and copies thereof) relating
to the Confidential Information, 



                                       5

<PAGE>   6

or to the work product or the business of the Company or any of its subsidiaries
or affiliates, which he may then possess or have under his control.

                    7.     NON-COMPETE, NON-SOLICITATION.

                    (a) Executive acknowledges that in the course of his
employment with the Company he will become familiar, and during the course of
his employment by D.M. Pub.'s predecessor prior to the date of this Agreement he
has become familiar, with trade secrets and customer lists of and other
confidential information concerning the Company and its subsidiaries and
affiliates and predecessors thereof and that his services have been and will be
of special, unique and extraordinary value to the Company.

                    (b) Executive agrees that during the Employment Period and
for a period of three years after termination of his employment with the Company
he shall not in any manner, directly or indirectly, through any person, firm or
corporation, alone or as a member of a partnership or as an officer, director,
stockholder, investor or employee of or in any other corporation or enterprise
or otherwise, engage or be engaged in, or assist any other person, firm,
corporation or enterprise in engaging or being engaged in, anywhere in the
world, the publishing or production of any Business Information Product (as
defined in the Combination Agreement) that competes with a Business Information
Product being published or produced by the Company or any of its subsidiaries or
affiliates when the Employment Period ends.

                    (c) Executive further agrees that during the Employment
Period and for three years thereafter he shall not in any manner, directly or
indirectly, induce or attempt to induce any employee of the Company or of any of
its subsidiaries or affiliates to quit or abandon his/her employ.

                    (d) Nothing in this Paragraph shall prohibit Executive from
being: (i) a stockholder in a mutual fund or a diversified investment company or
(ii) a passive owner of not more than 5% of the outstanding equity securities of
any class of a corporation or other entity which is publicly traded, so long as
Executive has no active participation in the business of such corporation or
other entity.

                    (e) If, at the time of enforcement of this Paragraph, a
court holds that the restrictions stated herein are unreasonable under
circumstances then existing, the parties hereto agree that the maximum period,
scope or geographical area reasonable under such circumstances shall be
substituted for the stated period, scope or area and that the court shall be
allowed to revise the restrictions contained herein to cover the maximum period,
scope and area permitted by law.

                    (f) The provisions of (b) of this Paragraph shall not apply
following a Termination without Cause or a Termination by Executive for Good
Reason.

                    8. ENFORCEMENT. Because Executive's services are unique and
because Executive has access to Confidential Information and work product, the
parties hereto agree that the Company would be damaged irreparably in the event
any of the provisions of Paragraph 6 or 7 hereof were not performed in
accordance with their specific terms or were otherwise breached and that money


                                       6

<PAGE>   7



damages would be an inadequate remedy for any such non-performance or breach.
Therefore, the Company or its permitted successors or assigns shall be entitled,
in addition to other rights and remedies existing in their favor, to an
injunction or injunctions to prevent any breach or threatened breach of any of
such provisions and to enforce such provisions specifically (without posting a
bond or other security).

                    9. EXECUTIVE REPRESENTATIONS. Executive represents and
warrants to the Company that (i) the execution, delivery and performance of this
Agreement by Executive does not and will not conflict with, breach, violate or
cause a default under any contract, agreement, instrument, order, judgment or
decree to which Executive is a party or by which he is bound, (ii) with the
exception of the Combination Agreement, Executive is not a party to or bound by
any employment agreement, noncompete agreement or confidentiality agreement with
any other person or entity and (iii) upon the execution and delivery of this
Agreement by the Company, this Agreement shall be the valid and binding
obligation of Executive, enforceable in accordance with its terms.

                    10. SURVIVAL. Subject to any limits on applicability
contained therein, Paragraphs 6, 7 and 8 hereof shall survive and continue in
full force in accordance with their terms notwithstanding any termination of the
Employment Period.

                    11. NOTICES. Any notice provided for in this Agreement shall
be in writing and shall be either personally delivered, sent by reputable
overnight carrier or mailed by first class mail, return receipt requested, to

sent or mailed.

                    12. SEVERABILITY. Whenever possible, each provision of this
Agreement shall be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Agreement is held to be invalid,
illegal or unenforceable in any respect under any applicable law

                                       7
<PAGE>   8


or rule in any jurisdiction, such invalidity, illegality or unenforceability
shall not affect any other provision or any other jurisdiction, but this
Agreement shall be reformed, construed and enforced in such jurisdiction as if
such invalid, illegal or unenforceable provision had never been contained
herein.

                    13. COMPLETE AGREEMENT. This Agreement embodies the complete
agreement and understanding between the parties with respect to the subject
matter hereof and effective upon the commencement of the Employment Period
supersedes and preempts any prior understandings, agreements or representations
by or between the parties, written or oral, which may have related to the
subject matter hereof in any way.

                    14. COUNTERPARTS. This Agreement may be executed in separate

inure to the benefit of and be enforceable by Executive, the Company and their
respective heirs, executors, personal representatives, successors and assigns,
except that neither party may assign any of his or its rights or delegate any of
his or its obligations hereunder without the prior written consent of the other
party. Executive hereby consents to the assignment by the Company of all of its
rights and obligations hereunder to: (i) any subsidiary or affiliate of the
Company in the event all or any substantial part of the business to which
Executive's duties under this Agreement relate are transferred thereto on or
after January 1, 2000 and (ii) any successor to the Company by merger or
consolidation or purchase of all or substantially all of the Company's assets;
in each case provided such transferee or successor assumes the liabilities of
the Company hereunder.

                    16. CHOICE OF LAW. This Agreement shall be governed by the
internal law, and not the laws of conflicts, of the State of Ohio.

                    17. AMENDMENT AND WAIVER. The provisions of this Agreement
may be amended or waived only with the prior written consent of the Company and
Executive, and no course of conduct or failure or delay in enforcing the
provisions of this Agreement shall affect the validity, binding effect or
enforceability of this Agreement.

IN WITNESS WHEREOF, the parties hereto have executed this Agreement on the date
first written above.
