<PAGE>   12

     (c) PURCHASE PRICE. (i) (i) In full consideration for the transfer of
Duke's DII Shares and the Sellers' DCI partnership interests, Penton will
deliver and pay to Sellers a total purchase price of up to $150 million in cash
(the Purchase Price). The Purchase Price is payable in two parts as follows: (1)
at Closing, Penton will pay to the Sellers $100 million in cash, subject to the
adjustment provided in section 2(g)(i) below (the Cash Payment), by wire
transfer or delivery of other immediately available funds and (2) Contingent
Payments of up to $50 million, if earned, due over a period following Closing as
described in this section 2(c). The Contingent Payments consist of a Revenue
Contingent Payment and an EBITDA Contingent Payment, each defined below, to be
paid by Penton, if earned, on or before March 31 following the end of each of
the calendar years 2000, 2001 and 2002 (each, a "Yearly Contingent Payment
Period" and collectively the "Contingent Payment Period,") and in accordance
with the procedures set forth in this section 2(c). The Parties agree that the
consideration for the DII Shares consists solely of a portion of the Cash
Payment and none of the Contingent Payments. The consideration for the DCI
interests is the balance of the Cash Payment and all of the Contingent Payments.
The final allocation of the Purchase Price among the Sellers shall be determined
in a writing executed by all Sellers and Penton on or before two business days
before the Closing Date. The Sellers will, at Closing, assign their rights to
receive the Contingent Payments to a newly formed limited liability company (New
LLC) that will be wholly owned by Sellers. Penton shall pay all Contingent
Payments, if earned, by wire transfer to New LLC. Sellers acknowledge that
payment of the Contingent Payment to New LLC pursuant to this section 2(c) is in
complete satisfaction of Penton's obligations under this section 2(c) to pay the
Purchase Price to Sellers. Any Contingent Payment that is not paid when due
shall accrue interest from the due date until paid at the Applicable Rate;
PROVIDED, HOWEVER, that, if the amount of any Contingent Payment is in dispute,
it will not be

                                       8
<PAGE>   13

considered due until the later of March 31 of the year following the end of the
applicable Yearly Contingent Payment Period and five business days after
resolution of such dispute.

     (ii) (A) The "Revenue Contingent Payment" is equal to 24% of the amount by
which revenue (as adjusted as provided by section 2(c)(vi) hereof) generated by
the business of the Companies and the DCI Subsidiary (the Business) in respect
of such year exceeds $50 million; PROVIDED, HOWEVER, that the total cumulative
amount of the Revenue Contingent Payment that may be earned during the
Contingent Payment Period will not exceed $30 million; PROVIDED, FURTHER, that
if the total cumulative amount of the Revenue Contingent Payment earned during
the Contingent Payment Period does not equal at least $15 million, an additional
Yearly Contingent Payment Period, calendar year 2003, will be added to the
Contingent Payment Period to achieve up to, but not more than, a total
cumulative Revenue Contingent Payment of $15 million. For example, the annual
Revenue Contingent Payments for 2000, 2001, 2002 and, if applicable, 2003, would
be as follows if the revenues of the Business were in the amounts indicated
below (subject, however, to the $30 million maximum Revenue Contingent Payment
amount):

</TABLE>


     The amount of any Revenue Contingent Payment earned will be reduced by any
amounts that are due to Penton pursuant to section 2(f) or section 10(f) hereof.
Revenue, for purposes of this section 2(c), will be determined in accordance
with GAAP on an accrual basis, consistently applied by Penton from period to
period in a manner consistent with DCI's accounting practices as reflected in
the Financial Statements if DCI's accounting practices are consistent with GAAP.

     (B) The "EBITDA Contingent Payment" is equal to 56% of the amount by which
EBITDA (as adjusted as provided by section 2(c)(vi) hereof) of the Business in
respect of such year exceeds $8 million; PROVIDED, HOWEVER, that the total
cumulative amount of the EBITDA Contingent Payment that may be earned during the
Contingent Payment Period will not exceed $20 million. For example, the annual
EBITDA Contingent Payments for 2000, 2001 and 2002

                                       10

would be as follows if the EBITDA of the Business were in the amounts indicated
below (subject, however, to the $20 million maximum EBITDA Contingent Payment
amount):

                  (C) "EBITDA" means for any fiscal period, the sum of net
income determined in accordance with GAAP on an accrual basis, consistently
applied by Penton from period to period in a manner consistent with DCI's
accounting practices as reflected in the Financial Statements if DCI's
accounting practices are consistent with GAAP, plus, to the extent deducted in
computing net income, interest expense, income tax expense, all depreciation
and, without duplication, all amortization, plus or minus, as the case may be,
other extraordinary income or expense items, whether unrelated to the operation
of the Business or incurred in the usual and ordinary course of the operation of
the Business. The EBITDA of the Business will be determined initially by Penton.
Notwithstanding the foregoing, the calculation of EBITDA of the Business for
purposes of this subsection will not include allocations of Penton's general
corporate overhead costs except as provided herein, but will include (x)
operating expenses directly related to the Business including, without
limitation, (i) retirement and welfare plan contribution costs for employees
involved in management and operation of the Business, (ii) casualty and
liability insurance premiums allocable to operation of the Business, (iii)
employee costs for personnel whose work is principally related to operation of
the Business, and (iv) other charges incurred by Penton in the ordinary course
of business of operating the Business that may

                                       11
<PAGE>   16

differ in amount, nature and type from those previously incurred by DCI in
operating the Business, (y) general and administrative expenses directly related
to the Business, and (z) indirect services, including accounting and services
currently performed by third party vendors (other than those of the type set
forth in (x) and (y) above), to the extent such costs and expenses do not exceed
DCI's current cost for such services. Without limiting the generality of the
foregoing, EBITDA of the Business will account for any cost savings realized as
a result of the Business being operated by DII as a subsidiary of Penton,
including by using services provided by Penton.

         (iii) If additional working capital is required to expand the Business,
advances by Penton for such purposes will bear interest at the average borrowing
rate from time to time of Penton. Such interest charge will be deducted in
determining EBITDA.

         (iv) Penton shall provide its initial determination of revenue and
EBITDA of the Business for the previous Yearly Contingent Payment Period to DCI
within 60 days of the end of the previous Yearly Contingent Payment Period (the
Revenue/EBITDA Determination). Penton shall include in the Revenue/EBITDA
Determination an unaudited operating profit and loss statement of the Business
for the respective Contingent Payment Period, certified by the chief financial
officer of Penton as being in accordance with GAAP on an accrual basis,
consistently applied by Penton from period to period in a manner consistent with
DCI's accounting practices as reflected in the Financial Statements if DCI's
accounting practices are consistent with GAAP. Unless Duke, within fifteen
business days after receipt of the Revenue/EBITDA Determination, notifies Penton
that it objects to the computation of revenue and/or EBITDA as set forth in the
Revenue/EBITDA Determination, the Revenue/EBITDA Determination will be binding
upon the parties for such Yearly Contingent Payment Period. If

                                       12
<PAGE>   17

Duke objects to Penton's calculation of revenue and/or EBITDA as set forth in
the Revenue/EBITDA Determination, not later than fifteen business days following
delivery to Sellers of the Revenue/EBITDA Determination, Duke shall notify
Penton in writing of such objection (the Objection). The Objection must specify
(a) the amount of the proposed adjustment to revenue and/or EBITDA as set forth
in the Revenue/EBITDA Determination; (b) the item(s) to which such Objection
relates; and (c) the facts and circumstances supporting the Objection. During
the 10 business-day period following the delivery to Penton of any Objection,
Penton and Duke will discuss Duke's proposals in the Objection and endeavor in
good faith to reach agreement upon appropriate adjustments to the Revenue/EBITDA
Determination. If Penton and Duke are unable to agree upon the revenue and/or
the EBITDA for the previous Yearly Contingent Payment Period during such 10
business-day period, then Penton and Duke will jointly engage a mutually
acceptable, independent accounting firm to resolve the dispute in a manner
consistent with the procedures set forth in section 2(f)(ii).

         (v) Sellers acknowledge that Penton will own and control the Business
and that, after the Closing, Penton may operate the Business in such manner as
it determines to be in its best interest; PROVIDED, HOWEVER, that Penton shall
use its reasonable best efforts to maximize revenue and EBITDA of the Business.
Throughout the Contingent Payment Period, Penton will promptly provide to Duke
copies of all written reports, financial statements, projections, budgets,
studies and other similar analysis concerning DII, the DCI Subsidiary or the
Business made available to management of the Companies.

         (vi) If Penton, the Companies or the DCI Subsidiary sell or in anyway
transfer (i) control of any of the Companies and the DCI Subsidiary (a Sold
Company) or (ii) any asset or group of assets comprising a magazine, newsletter,
web site or other business unit of the

                                       13
<PAGE>   18

Business acquired from Sellers as the Business existed as of the Closing Date (a
Sold Business Unit) during the Contingent Payment Period to a Person that is not
controlled by, under common control with, or controlling Penton, then, in
calculating the Revenue Contingent Payment and the EBITDA Contingent Payment,
the actual revenue and EBITDA of the Business will be increased by the
annualized amount of revenue and EBITDA, respectively, contributed by the Sold
Company or Sold Business Unit to the Business during the most recent 12-month
period before completion of such sale or transfer multiplied by the average
annual growth rate of such Sold Company or Sold Business Unit during the most
recent 24-month period before completion of such sale or transfer. For example,
if (i) the Sold Company or Sold Business Unit contributed $10 million of revenue
and $1 million of EBITDA during the most recent 12-month period before the sale
is completed, (ii) the average annual growth rate for such Sold Company or Sold
Business Unit over the 24-month period before the sale is completed is 10% and
(iii) the sale is completed on September 30, 2001, then (x) the actual revenue
of the Business for the 2001 Yearly Contingent Period will be increased by $2.75
million ($10 million x 10% growth rate (1.1 factor) x 0.25 (3 mos/12 mos)) and
the actual revenue of the Business for the 2002 Yearly Contingent Period will be
increased by $11 million ($10 million x 10% x 1.0 (12 mos/12 mos)) and (y) the
actual EBITDA of the Business for the 2001 Yearly Contingent Period will be
increased by $275,000 ($1 million x 10% x .25) and the actual EBITDA of the
Business for the 2002 Yearly Contingent Period will be increased by $1.1 million
($1 million x 10% x 1.0). Any sales or transfers to a Person that is controlled
by, under common control with or controlling Penton will not affect the
calculation of revenue or EBITDA for purposes of calculating the Revenue
Contingent Payment or the EBITDA Contingent Payment.

     (d) THE CLOSING. The closing of the transactions contemplated by this
Agreement (the Closing) shall take place at the offices of Minor & Brown, P.C.
in Denver, Colorado commencing at 9:00 a.m. local time on the second business
day following the satisfaction or waiver of all conditions to the obligations of
the Parties to consummate the transactions contemplated hereby (other than
conditions with respect to actions the respective Parties will take at the
Closing itself) or such other date as the Parties may mutually determine (the
Closing Date).

     (e) DELIVERIES AT THE CLOSING. At the Closing, (i) Sellers will deliver to
Penton, or DII as its Subsidiary, the various certificates, instruments, and
documents referred to in section 7(a) below and such other duly executed
documents and certificates as may be reasonably requested to be delivered by
Penton pursuant to the terms of this Agreement; and (ii) Penton will deliver to
Sellers the Purchase Price as specified in section 2(c) above and the various
certificates, instruments, and documents referred to in section 7(b) below and
such other duly executed documents and certificates as may be reasonably
requested to be delivered by Sellers pursuant to the terms of this Agreement.

     (f) PURCHASE PRICE ADJUSTMENT. (i) (i) The Purchase Price will be increased
by the amount by which the Closing Working Capital exceeds zero or decreased by
the amount by which the Closing Working Capital is less than zero. An estimate
of Closing Working Capital shall be determined in good faith by Sellers
immediately prior to Closing (Estimated Closing Working Capital) and used in
determining the Purchase Price payable at Closing pending a final, post-Closing,
determination in accordance with this section 2(f).

         (ii) Within 90 calendar days after the Closing Date, Penton at its
expense, shall prepare and deliver to Sellers a balance sheet of DCI prepared in
accordance with GAAP,

                                       15
<PAGE>   20

 as used for the Financial Statements as of the close of
business on the last business day immediately preceding the Closing Date;
PROVIDED, HOWEVER, that, if the Closing occurs within the first ten days of the
prior month end, then the balance sheet will be prepared as of the close of
business on the last business day of the month end prior to Closing (the Closing
Balance Sheet). Closing Working Capital will be the Working Capital reflected on
the Closing Balance Sheet. Working Capital means current assets minus current
liabilities, excluding (i) any deferred subscription revenue, (ii) any accrued
expense relative to the Duke Communications International, L.L.L.P. Equity
Rights Appreciation Plan, and (iii) any current liabilities of DCI or DII
retained by the Sellers or against which the Sellers are obligated to indemnify
Penton and DII in accordance with this Agreement, but including as a current
liability the long-term portion of the Promissory Notes dated April 7, 2000, and
August 15, 2000, payable to First National Bank. Within 45 calendar days after
Penton's delivery of the Closing Balance Sheet, Duke shall deliver to Penton a
written statement describing the objections (if any) to the Closing Balance
Sheet. If Duke does not deliver a written statement within those 45 days, the
Closing Working Capital reflected on the Closing Balance Sheet will be final and
binding. If Duke does deliver a written statement within those 45 calendar days,
Duke and Penton shall attempt to resolve any disputed items, but if within 60
calendar days of Duke's delivery of a statement of objections to Penton any
disputes remain open, Duke and Penton shall select a mutually acceptable
independent accounting firm to resolve said disputes. If Penton and Duke are
unable to mutually agree on such an accounting firm within ten calendar days, an
accounting firm will be selected by lot from among the "Big 5" after eliminating
any Big 5 firms representing a Party and after eliminating one firm designated
as objectionable by each of Duke on the one hand and Penton on the other hand.
The Parties shall cause said firm to resolve any disputed items as soon as

                                       16
<PAGE>   21

practicable and the determination of that firm shall be final and binding. Said
firm will make its determination in accordance with GAAP, as used in the Most
Recent Financial Statements based solely upon the presentations by Penton and
Duke and only with respect to the differences submitted by Penton and Duke. The
determination by said firm may not be for an amount that is outside of the range
of Penton's and Duke's disagreement or consider items that are not in dispute.
The costs and expenses incurred in connection with a determination by the
selected firm shall be allocated by that firm, in its discretion, in proportion
to the relative success of the Parties as to the dispute.

         (iii) As soon as practicable, but in no event later than five calendar
days, after the Closing Working Capital has been finally determined pursuant to
this section 2(f), the difference between Closing Working Capital and Estimated
Closing Working Capital, plus simple interest on that amount at the Applicable
Rate from Closing to the date of payment, shall be paid by Penton (in the case
of a positive difference) or by the Sellers (in the case of a negative
difference) to the other Party as the adjustment to the Cash Payment portion of
the Purchase Price

     3. REPRESENTATIONS AND WARRANTIES OF THE SELLERS. Each of the Sellers

the right to accelerate, terminate, modify, or cancel, or require any notice

Disclosure Schedule, free and clear of any restrictions on transfer (other than
any restrictions under the Securities Act and state securities laws), Taxes,
Security Interests, options, warrants, purchase rights, contracts, commitments,
equities, claims, and demands. None of the Sellers are party to any option,
warrant, purchase right, or other contract or commitment that could require a
Seller to sell, transfer, or otherwise dispose of any partnership interest,
capital stock, or other equity in either of the Companies (other than this
Agreement). None of the Sellers are party to any voting trust, proxy, or other

operations, or future prospects of the Companies, taken as a whole. Section 4(a)
of the Disclosure Schedule lists the directors and officers of each of the
Companies.

     (b) CAPITALIZATION. The entire authorized capital stock of the DII consists

of the partnership interests of DCI. DII owns the remaining ten percent (10%)
interest, consisting of nine percent (9%) as a limited partner and one percent
(1%) as the sole general partner. A true and correct copy of the Limited
Partnership Agreement of DCI has been provided or made available to Penton.

Interest upon any of the Companies' or the DCI Subsidiary's assets), except
(other than with respect to the Limited Partnership Agreement of DCI, the
Articles of Incorporation and Bylaws of DII and the constituent documents of the
DCI Subsidiary) where the violation, conflict, breach, default, acceleration,

Subsidiary or on the ability of the Parties to consummate the transactions

or obligation to pay any fees or commissions to any Person with respect to the

marketable title to, or a valid leasehold interest in, the properties and assets
used by it, located on its premises, or shown on the Most Recent Balance Sheet
or acquired after the date thereof, free and clear of all Security Interests,

since the date of the Most Recent Balance Sheet. The assets, properties, rights
and contracts of the Companies and the DCI Subsidiary include all of the assets,
properties, rights and contracts necessary for the conduct of the Business in
substantially the same manner as currently conducted.

     (f) SUBSIDIARIES. DCI has no Subsidiaries. Section 4(f) of the Disclosure
Schedule sets forth for each Subsidiary of DII (i) its name and jurisdiction of
incorporation, (ii) the number of shares of authorized capital stock of each
class of its capital stock, (iii) the number of issued and outstanding shares of
each class of its capital stock, the names of the holders thereof, and the
number of shares held by each such holder, (iv) the number of shares of its

operations of the Companies and the DCI Subsidiary. Each Subsidiary of DII has
full corporate power and authority to carry on the businesses in which it is
engaged and to own and use the properties owned and used by it. All of the
issued and outstanding shares of capital stock of each Subsidiary of DII have

Closing Balance Sheet. For purposes of this Section, in the case of any Taxes
that are imposed on a periodic basis and are payable for a Taxable period that
includes (but does not end on) the Closing Date, the portion of such Tax which
relates to the portion of such Taxable period ending on the Closing Date shall
(x) in the case of any Taxes other than Income Taxes, be deemed to be the amount
of such Tax for the entire Taxable period multiplied by a fraction, the
numerator of which is the number of days in the Taxable period ending on the
Closing Date and the denominator of which is the number of days in the entire
Taxable period, and (y) in the case of any Tax based upon or related to income
or receipts, be deemed equal to the amount which would be payable if the
relevant Taxable period ended on the Closing Date. Any credits relating to a
Taxable period that begins before

                                       54
<PAGE>   59

and ends after the Closing Date shall be taken into account as though the
relevant Taxable period ended on the Closing Date. All determinations necessary
to give effect to the foregoing allocations shall be made in a manner consistent
with prior practice of the Companies and the DCI Subsidiary.

         (iii) REFUNDS AND TAX BENEFITS. Any Tax refunds that are received by
Penton, the Companies or the DCI Subsidiary, and any amounts credited against
Tax to which Penton, the Companies or the DCI Subsidiary become entitled, that
relate to Tax periods or portions thereof ending on or before the Closing Date
shall be for the account of Sellers, and Penton shall pay over to the respective
Sellers any such refund or the amount of any such credit within 15 calendar days
after receipt or entitlement thereto. In addition, to the extent that a claim
for refund or a proceeding results in a payment or credit against Tax by a
taxing authority to Penton, the Companies or the DCI Subsidiary of any amount
accrued on the Closing Balance Sheet, Penton shall pay such amount to the
respective Sellers within 15 calendar days after receipt or entitlement thereto.

         (iv) COOPERATION ON TAX MATTERS. Penton, for itself and on behalf of
the Companies and the DCI Subsidiary, and Sellers shall cooperate fully, as and
to the extent reasonably requested by the other party, in connection with the
filing of Tax Returns of the Companies or the DCI Subsidiary pursuant to this
Section and any audit, litigation, or other proceeding with respect to Taxes of
the Companies or the DCI Subsidiary. Such cooperation shall include the
retention and (upon the other party's request) the provision of records and
information which are reasonably relevant to any such audit, litigation, or
other proceeding and making employees available on a mutually convenient basis
to provide additional information and explanation of any material provided
hereunder. Penton shall cause DII, DCI and the DCI

                                       55
<PAGE>   60

Subsidiary (A) to retain all books and records with respect to the DCI
Subsidiary relating to any Taxable period beginning before the Closing Date
until the expiration of the statute of limitations (and, to the extent notified
by Sellers, any extensions thereof) of the respective Taxable periods, and to
abide by all record retention agreements entered into with any Taxing Authority,
and (B) to give Sellers reasonable written notice prior to transferring,
destroying or discarding any such books and records and, if Sellers so requests,
Penton shall cause DCI, DII or the DCI Subsidiary, as the case may be, to allow
Sellers to take possession of such books and records. Penton and Sellers shall,
upon request, use reasonable efforts to obtain any certificate or other document
from any governmental authority or any other Person as may be necessary to
mitigate, reduce or eliminate any Tax that could be imposed (including, but not
limited to, with respect to the transactions contemplated hereby).

         (v) CERTAIN REIMBURSEMENTS BY PENTON. Penton will reimburse Sellers for
up to the first $500,000 of interest expense incurred by Sellers under section
453A of the Code with respect to the EBITDA Contingent Payments provided in the
Purchase Price. The Parties agree that the interest expense shall be determined
by Sellers in accordance with Code section 453A, and the regulations thereunder;
provided, however, that the "applicable percentage" defined in section 453A (c)
(4) shall be deemed to be 100%. Penton shall reimburse Sellers for such interest
charges within 15 calendar days after notice from Duke of the Sellers' payment
of such amounts, which notice shall contain Sellers' calculation of the interest
charges, including reasonable supporting documentation, and proof of payment.

     (e) EMPLOYEE BENEFITS MATTERS. Penton will ensure that any Employee Benefit
Plans it adopts with respect to the employees of DCI or the DCI Subsidiary treat
employment with any of the Companies and the DCI Subsidiary prior to the Closing
Date the same as employment with

                                       56
<PAGE>   61

any of Penton and the DCI Subsidiary from and after the Closing Date for
purposes of eligibility, vesting, and benefit accrual; PROVIDED, HOWEVER, that
there shall be no benefit accrual under the Penton Media, Inc. Retirement Plan
or any other "employee pension benefit plan" as defined in Section 3(2) of
ERISA.

     10. REMEDIES FOR BREACHES OF THIS AGREEMENT.

obligation of Sellers, DCI, DII or the DCI Subsidiary under this Agreement (or

Consulting Agreement, which will be governed by its terms), (5) any liability or
obligation of DCI, DII or the DCI Subsidiary arising under Environmental,

Subsidiary for all Pre-Closing Tax Periods and (7) any liability or obligation
of any of DCI, DII or the DCI Subsidiary that may arise out of the matters
described in Section 4(a)(1) of the Disclosure Schedule.

         (ii) In the event Sellers breach any of their representations,
warranties, and covenants contained in this Agreement (other than section 4 (i),
the breach of which is covered in (iii) below) or in any agreement or
certificate delivered at Closing in accordance with this Agreement, then Sellers
jointly and severally agree to indemnify and hold harmless Penton from and
against the entirety of any Adverse Consequences (except as limited in section
10(b)(iv)) Penton may suffer as a result of the breach through and after the
date of the claim for indemnification (including any Adverse Consequences Penton
may suffer after the end of eighteen months with respect to those
representations and warranties whose survival is limited to eighteen months);
PROVIDED, HOWEVER, that, for purposes of this provision, with respect to any
representation or warranty made by Sellers in section 3 or section 4, which by
its terms contains any qualification or limitation with respect to knowledge or
materiality, such misrepresentation or inaccuracy thereof will be deemed to have
occurred (and indemnification in respect thereof will be available hereunder) if
there would have

                                       58
<PAGE>   63

been a misrepresentation or inaccuracy in such representation or warranty absent
such qualification or limitation. Any written claim for indemnification made
under this section 10(b)(ii) shall be specific as to the representation,
warranty or covenant allegedly breached and shall include reasonable supporting
documentation.

         (iii) Sellers will also jointly and severally indemnify and hold
harmless Penton from and against Adverse Consequences Penton may suffer (A)
because of a breach of the representations and warranties contained in section

since the Most Recent Fiscal Month End in the Ordinary Course of Business, (2)
the liability of DCI to deliver the periodicals represented by the Deferred
Subscription Liability, (3) all contractual obligations of the Companies or the
DCI Subsidiary, (4) all liabilities and obligations of DCI under its Employee

profit sharing plan referenced in section 4(p)(vii)(6) of the Disclosure
Schedule, or any Adverse Consequences that arise as a result of a breach of a
representation or warranty of section 4(v)), and (5) all liabilities of the
Companies for transfer, sales, use, and other taxes arising in connection with
the consummation of the transactions contemplated hereby (the liabilities
described in clauses (1) through (5) being collectively referred to herein as
the Assumed Liabilities); PROVIDED, HOWEVER, that Penton may not seek indemnity
under both "10(b)(ii) hereof and this "10(b)(iii) for the same Adverse
Consequences if both provisions are applicable.

                                       59
<PAGE>   64

         (iv) Sellers shall have no obligation to indemnify Penton from and
against any Adverse Consequences under section 10(b)(ii) or (iii) until Penton
has suffered Adverse Consequences under one or both sections in excess of an
aggregate, combined deductible of $1,000,000 (in which event Sellers will be
obligated to indemnify Penton, and Penton may assert its right to
indemnification hereunder only with respect to Adverse Consequences that are
more than $1,000,000). Sellers obligation to indemnify Penton from and against
Adverse Consequences under section 10(b)(ii) is limited to $25,000,000. Sellers
obligation to indemnify Penton from and against Adverse Consequences under
section 10(b)(iii) is limited equal to $50,000,000. The caps described in the
preceding two sentences are separate and apply independently of each other.
Neither the basket nor the caps described in this section 10(b)(iv) will apply
to any claim made by Penton (1) under section 10 (b)(i), (2) for fraud, (3)
based on a misrepresentation or inaccuracy of the representations and warranties
contained in any of section 3 or section 4(a), (b), (d), (e), (f), (k), (v) or
(x), or (4) a breach of any covenant of Sellers contained in this Agreement.

     (c) INDEMNIFICATION PROVISIONS FOR BENEFIT OF SELLERS.

         (i) In the event Penton breaches any of its representations,
warranties, and covenants contained in this Agreement or in any agreement or
certificate delivered at Closing in accordance with this Agreement, then Penton
agrees to indemnify and hold harmless all Sellers from and against the entirety
of any Adverse Consequences any Seller may suffer as a result of the breach
through and after the date of the claim for indemnification (including any
Adverse Consequences Sellers may suffer after the end of eighteen months with
respect to those representations and warranties whose survival is limited to
eighteen months). Any written claim for indemnification made under this section
10(c)(i) shall be specific as to the representation, warranty or covenant
allegedly breached and shall include reasonable supporting documentation.

                                       60
<PAGE>   65

         (ii) Penton agrees to indemnify and hold harmless Sellers from and
against any Adverse Consequences they may suffer by the failure of Penton to
honor any Assumed Liability.

         (iii) Penton further agrees to indemnify and hold harmless the Sellers
from and against any Adverse Consequence resulting from Penton's operation of
the business of DCI, DII or the DCI Subsidiary after the Closing Date.

     (d) MATTERS INVOLVING THIRD PARTIES.

         (i) If any third party shall notify any Party (the Indemnified Party)
with respect to any matter (a Third Party Claim) which may give rise to a claim
for indemnification against the other Party (the Indemnifying Party) under this
section 10, then the Indemnified Party shall promptly notify each Indemnifying
Party thereof in writing; provided, however, that no delay on the part of the
Indemnified Party in notifying any Indemnifying Party shall relieve the
Indemnifying Party from any obligation hereunder unless (and then solely to the
extent) the Indemnifying Party thereby is prejudiced.

         (ii) Any Indemnifying Party will have the right to assume the defense
of the Third Party Claim with counsel of its choice reasonably satisfactory to
the Indemnified Party at any time within 30 days after the Indemnified Party has
given notice of the Third Party Claim; provided, however, that the Indemnifying
Party must conduct the defense of the Third Party Claim actively and diligently
thereafter in order to preserve its rights in this regard; and provided further
that the Indemnified Party may retain separate co-counsel at its sole cost and
expense and participate in the defense of the Third Party Claim.

         (iii) So long as the Indemnifying Party has assumed and is conducting
the defense of the Third Party Claim in accordance with section 10(d)(ii) above,
(A) the Indemnifying

                                       61
<PAGE>   66

Party will not consent to the entry of any judgment or enter into any settlement
with respect to the Third Party Claim without the prior written consent of the
Indemnified Party (not to be withheld unreasonably) unless the judgment or
proposed settlement involves only the payment of money damages by the
Indemnifying Party and does not impose an injunction or other equitable relief
upon the Indemnified Party and (B) the Indemnified Party will not consent to the
entry of any judgment or enter into any settlement with respect to the Third
Party Claim without the prior written consent of the Indemnifying Party (not to
be withheld unreasonably).

         (iv) In the event the Indemnifying Party does not assume and conduct
the defense of the Third Party Claim in accordance with section 10(d)(ii) above,
however, (A) the Indemnified Party may defend against, and consent to the entry
of any judgment or enter into any settlement with respect to, the Third Party
Claim in any manner it reasonably may deem appropriate (and the Indemnified
Party need not consult with, or obtain any consent from, any Indemnifying Party
in connection therewith) and (B) the Indemnifying Party will remain responsible
for any Adverse Consequences the Indemnified Party may suffer resulting from,
arising out of, relating to, in the nature of, or caused by the Third Party
Claim to the fullest extent provided in this section 10.

     (e) ADJUSTMENT TO PURCHASE PRICE. All indemnification payments under this
section 10 shall be deemed adjustments to the Purchase Price.

     (f) DETERMINATION OF ADVERSE CONSEQUENCES. The amount of any Adverse
Consequence subject to indemnification hereunder or any claim therefore shall be
calculated net of any insurance proceeds (net of direct collection expenses and
taxes with respect thereto) received or receivable by Penton, the Companies or a
DCI Subsidiary on account of such loss if such proceeds are payable with respect
to a policy, and during a policy period, for which the

                                       62
<PAGE>   67

premiums were paid by the Sellers, the Companies or the DCI Subsidiary before
the Closing Date.

     (g) SETOFF. If, after following the procedures set forth in this section
10, it has been determined that either party is entitled to an indemnification
payment from the other party with respect to a Third Party Claim, and the
Indemnifying Party fails to make such payment within five business days of such
determination, in addition to any and all other remedies under this Agreement or
at law or in equity, the Indemnified Party shall be entitled to recover any such
indemnification payment (whether or not such amount is liquidated or reduced to
judgment) by retaining and setting off such amounts against any amounts due or
to become due from the Indemnifying Party under this Agreement, including,
without limitation, any purchase price adjustment pursuant to section 2(f)
hereof. If any claim for indemnification other than with respect to a Third
Party Claim is made and the claim is not settled or the Parties are unable to
reach an agreement for the settlement of the claim within 90 days of the written
claim for indemnification, then the indemnified party will be entitled to direct
payment of any amounts due or to become due from the indemnified party to the
indemnifying party, in an amount not to exceed the amount in controversy, to an
escrow agent to be held by such agent pending the resolution of the dispute
among the Parties. The Parties shall, in such event, enter into an escrow
agreement in substantially the form attached as Exhibit E to establish the
escrow contemplated by this Section.

                                       63
<PAGE>   68

     11. MISCELLANEOUS.

     (a) EXCLUSIVE REMEDY. No remedy conferred by any of the specific provisions
of this Agreement is intended to be exclusive of any other remedy and each
remedy will be cumulative and will be in addition to every other remedy given
hereunder or hereafter existing at law or in equity or by statute or otherwise.
No remedy will be deemed to be a limitation on the amount or measure of damages
resulting from any breach of this Agreement. The election of any one or more
remedies will not constitute a waiver of the right to pursue other available
remedies. Notwithstanding the foregoing and except as provided in section 10
hereof, no claim shall be brought or maintained by Penton or any of the
Companies or the DCI Subsidiary against Duke in his capacity other than as a
shareholder of DII or the DCI Subsidiary or as a limited partner of DCI by
virtue of or based upon any alleged misrepresentation or inaccuracy in or breach
of any of the representations, warranties or covenants of Sellers set forth in
this Agreement or any certificate delivered hereunder.

     (b) PRESS RELEASES AND PUBLIC ANNOUNCEMENTS. No Party shall issue any press
release or make any public announcement relating to the subject matter of this
Agreement prior to the Closing without the prior written approval of the other
Party; provided, however, that any Party may make any public disclosure it
believes in good faith is required by applicable law or any listing or trading
agreement concerning its publicly-traded securities (in which case the
disclosing Party will use its reasonable best efforts to advise the other Party
prior to making the disclosure).

     (c) NO THIRD-PARTY BENEFICIARIES. This Agreement shall not confer any
rights or remedies upon any Person other than the Parties and their respective
successors and permitted assigns.

                                       64
<PAGE>   69

     (d) ENTIRE AGREEMENT. This Agreement (including the documents referred to
herein) constitutes the entire agreement between the Parties and supersedes any
prior understandings, agreements, or representations by or between the Parties,
written or oral, to the extent they related in any way to the subject matter
hereof.

     (e) SUCCESSION AND ASSIGNMENT. This Agreement shall be binding upon and
inure to the benefit of the Parties named herein and their respective successors
and permitted assigns. The rights of the Sellers to receive the Purchase Price,
including the contingent portions thereof, are freely transferable by the
Sellers after prior written notice to Penton; otherwise, no Party may assign
either this Agreement or any of its rights, interests, or obligations hereunder
without the prior written approval of the other Party; provided, however, that
Penton may (i) assign any or all of its rights and interests hereunder to one or
more of its Affiliates and (ii) designate one or more of its Affiliates to
perform its obligations hereunder (in any or all of which cases Penton
nonetheless shall remain responsible for the performance of all of its
obligations hereunder).

     (f) COUNTERPARTS. This Agreement may be executed in one or more
counterparts, each of which shall be deemed an original but all of which
together will constitute one and the same instrument.

     (g) HEADINGS. The section headings contained in this Agreement are inserted
for convenience only and shall not affect in any way the meaning or
interpretation of this Agreement.

     (h) NOTICES. All notices, requests, demands, claims, and other

of any jurisdiction other than the State of Colorado.

     (k) AMENDMENTS AND WAIVERS. No amendment of any provision of this Agreement

Sellers. No waiver by any Party of any default, misrepresentation, or breach of
warranty or covenant hereunder, whether intentional or not, shall be deemed to
