                                   CONFIDENTIAL             FINAL EXECUTION COPY

                               EXECUTIVE AGREEMENT

            THIS EXECUTIVE AGREEMENT (this "Agreement") is made as of September
17, 2003 (the "Effective Date"), by and between Ziff Davis Media Inc., a
Delaware corporation (the "Company") and Paul O'Reilly ("Executive"). Certain
definitions are set forth in the Appendix to this Agreement.

            In consideration of the representations and covenants set forth
herein, the parties hereby agree as follows:

      1. Employment. The Company shall employ Executive, and Executive hereby
accepts employment with the Company, upon the terms and conditions set forth in
this Agreement for the period beginning September 22, 2003 and ending December
31, 2008 or earlier pursuant to Section 4 hereof (the "Employment Period").

      2. Position and Duties.

      (a) During the Employment Period, Executive shall (subject to promotion)
serve as the Vice President, Ziff Davis Events, of the Company and shall have
the normal duties, responsibilities and authority implied by such positions.
Executive shall hold similar positions with any Affiliate of the Company to the
extent Executive may be so appointed by the Company in its sole discretion.

      (b) Executive shall report directly to the Company's Chief Operating
Officer ("COO"), the Company's President ("President") and the Company's Chief
Executive Officer ("CEO") or such other senior Company executive as the CEO may
direct, and shall devote his best efforts and substantially all of his business
time and attention to the business and affairs of the Company (and to the extent
applicable, its Affiliates). Executive shall perform Executive's duties and
responsibilities to the best of Executive's abilities in a diligent and
professional manner.

      3. Base Salary; Benefits and Bonuses.

      (a) During the Employment Period, Executive's base salary shall be
$225,000 per annum, or such higher rate as the Company may designate from time
to time (the "Base Salary"), which salary shall be payable by the Company in
regular installments in accordance with the Company's general payroll practices.

      (b) In addition to the Base Salary, during the Employment Period Executive
shall be eligible to receive an annual bonus (the "Bonus") calculated from an
annual bonus pool (the "Bonus Pool") allocated by the Company to the TM Media
Principals. On or prior to March 31 of each calendar year, beginning with the
calendar year beginning January 1, 2004, the Company's board of directors, CEO,
President or CFO, after consultation by the CEO, President or CFO with one or
more of the TM Media Principals, shall approve a budget for the Initial Events
and their development and implementation which shall include a reasonable target
(the "Budgeted TM EBITDA") for TM EBITDA for such year and, during the
Employment Period, the Company shall give written notice of Budgeted TM EBITDA
to Executive within ten (10) business days after it has been approved by the
CEO, President or CFO of the Company; provided, however, that Budgeted TM EBITDA
for any particular calendar year shall, without more and without prejudice to
any other target being deemed reasonable, automatically be deemed to be
reasonable if (A) Budgeted TM EBITDA does not exceed the sum of (x) actual TM
EBITDA with respect to the immediately preceding calendar year plus (y) an
amount of additional EBITDA that reasonably may be projected for such year
taking into account the Company's preceding or anticipated capital expenditures,
economies of scale and similar efficiencies) or (B) TM Media Principals then
employed by the Company
<PAGE>
                                  CONFIDENTIAL


and holding at least 60% (based upon Personal Share percentages) of the
aggregate Personal Shares do not deliver written notice that they believe that
such Budgeted TM EBITDA is not reasonable within fifteen (15) days after receipt
of written notice of Budgeted TM EBITDA from the Company. If, for any calendar
year, TM EBITDA for such calendar year exceeds Budgeted TM EBITDA (such excess,
the "Excess Amount"), then the Company will allocate to the Bonus Pool an amount
equal to the lesser of (i) 50% of the aggregate base salaries for the relevant
calendar year for the TM Media Principals continuously employed by the Company
throughout the entire relevant calendar year and (ii) the Excess Amount. The
percentage determined by dividing (x) the amount required to be allocated to the
Bonus Pool pursuant to the immediately foregoing sentence by (y) the aggregate
base salaries for the relevant calendar year for the TM Media Principals
continuously employed by the Company throughout the entire relevant calendar
year is referred to herein as the "Bonus Percentage." On or before April 15 of
each year during the Employment Period, beginning April 15, 2005, the Company
shall pay Executive (provided Executive is still employed as a full-time
employee by the Company or any of its Affiliates on the date such payment is
made) an amount in cash equal to the product of (A) the Bonus Percentage
multiplied by (B) the Base Salary of Executive during such prior calendar year.
For example and without limiting the foregoing, if (i) Budgeted TM EBITDA for a
calendar year is $2,000,000, (ii) actual TM EBITDA for such calendar year is
$3,000,000 and (iii) the aggregate base salaries for such calendar year of the
TM Media Principals (all of whom were continuously employed by the Company
throughout the entire calendar year) is $850,000, then (A) the Bonus Pool shall
be $425,000, and (B) the Bonus Percentage shall be 50%. For example and without
limiting the foregoing, if (i) Budgeted TM EBITDA for a calendar year is
$2,000,000, (ii) actual TM EBITDA for such calendar year (before reduction on
account of the Bonus Pool for such calendar year) is $2,250,000 and (iii) the
aggregate base salaries for such calendar year of the TM Media Principals (all
of whom were continuously employed by the Company throughout the entire calendar
year) is $850,000, then (A) the Bonus Pool shall be $250,000 and (B) the Bonus
Percentage shall be 29%.

      (c) During the Employment Period, (i) Executive shall be entitled to
participate in all of the Company's employee benefit plans and programs for
which senior executive employees of the Company are generally eligible, which
currently include, but shall not be limited to, health insurance, dental
insurance, life insurance, short-term and long-term disability insurance and
participation in the Company's 401(k) plan and (ii) Executive shall be eligible
for three (3) weeks of paid vacation in accordance with the policies of the
Company. Executive's right to participate in any employee benefit plans or
programs of the Company shall be subject to the Company's right to amend, modify
or terminate any such plan or program in accordance with its terms and
applicable law and subject in each case to any applicable waiting periods or
other restrictions contained in such benefit plans or programs.

      (d) The Company shall reimburse Executive for all reasonable business
expenses incurred by Executive in the course of performing Executive's duties
under this Agreement which are consistent with the Company's policies in effect
from time to time for senior executive employees of the Company with respect to
travel, entertainment and other business expenses, subject to the Company's
requirements with respect to reporting and documentation of such expenses as per
Company policies.

      (e) All payments to Executive shall be subject to customary withholding as
may be required by law.

      4. Termination; Severance.

      (a) The Employment Period (i) shall terminate upon Executive's death; (ii)
may be terminated by the Company upon delivery of written notice to Executive at
any time with Cause or without Cause; (iii) may be terminated by Company for
Incapacity upon delivery of written notice to Executive within 30 days following
the end of the relevant Incapacity or while the relevant Incapacity is
continuing; and (iv)


                                       2
<PAGE>
                                  CONFIDENTIAL


may be terminated by Executive at any time upon delivery of written notice to
Company for Good Reason or other than for Good Reason. Executive acknowledges
and agrees that nothing contained herein or in any other agreement or document
shall entitle Executive to remain in the employment of the Company or any of its
Affiliates. "Termination" means such time as of which Executive ceases to be
employed by the Company, for any reason, whether on account of termination by
the Company, resignation by Executive, Executive's death or otherwise and
"Termination Date" means the date on which Termination occurs.

      (b) Upon any Termination, Executive shall be entitled to receive
Executive's Base Salary earned through the Termination Date, prorated on a daily
basis together with all accrued but unpaid vacation time earned by Executive
during the calendar year in which such Termination occurs, reimbursements of
expenses incurred during the Employment Period and reimbursable in accordance
with and after compliance with Company policies, and any Bonus in respect of a
prior, completed calendar year which is then due and owing and has not been
paid. Except as set forth in Section 4(d) or as required by applicable law,
Executive shall not be entitled to receive Executive's Base Salary or any
bonuses or other benefits from the Company in respect of any period after the
Termination Date.

      (c) In the event Executive's employment is terminated (i) by the Company
with Cause or for Incapacity, (ii) by Executive other than for Good Reason, or
(iii) upon Executive's death or upon any Termination on or after December 31,
2008, the Company shall have no obligation to make any severance or other
similar payment to or on behalf of Executive.

      (d) In the event that Executive's employment is terminated (i) by the
Company without Cause or (ii) by Executive for Good Reason (in either case prior
to December 31, 2008), following such Termination and upon execution and
delivery by Executive within thirty (30) calendar days after the Termination
Date of a general release in favor of the Company and its Affiliates and its and
their respective officers, directors, employees, representatives, agents and
attorneys, and the successors and assigns of each of the foregoing, in form and
substance satisfactory to the Company (provided, however, that the Company shall
not require such general release to include any claim alleging a right to
receive indemnification from the Company related to any action, suit or
proceeding that may be brought against Executive by any third party in
connection with Executive's status as an executive of the Company or any
payments or other rights to which Executive may be entitled under the Stock
Purchase Agreement), the Company shall, through the first (1st) anniversary of
the Termination Date, (x) pay Executive his annual Base Salary (as in effect on
the Termination Date) in regular installments in accordance with the Company's
general payroll practices and (y) if Executive elects under COBRA to maintain
health insurance benefits through the Company's group plan (if any), pay that
portion of the premium for such benefits that the Company would have paid had
Executive remained an employee of the Company for such period. After payment of
the severance amounts described in this Section 4(d), the Company shall have no
obligation to make any further severance or other payment or provide any other
benefit to or on behalf of Executive, other than payments that may become due
and owing to Executive in accordance with the terms of the Stock Purchase
Agreement. Notwithstanding the foregoing, in the event that Executive shall
breach any of Executive's obligations under Section 5 of this Agreement (except
any breach which Executive carries the burden of proving is solely of a
technical nature, is immaterial and was inadvertent) or Executive's obligations
pursuant to Section 5(a) of this Agreement are terminated as determined in
accordance with the terms hereof, then, in addition to any other rights that the
Company may have under this Agreement or otherwise, the Company shall be
relieved from and shall have no further obligation to pay Executive any amounts
to which Executive would otherwise be entitled pursuant to this Section 4.

      5. Noncompete, Non-Solicitation.

                                  CONFIDENTIAL


      (a) Noncompete. In further consideration of the compensation to be paid to
Executive hereunder, Executive acknowledges that in the course of Executive's
employment with the Company and any applicable Affiliate thereof, Executive will
during the Employment Period become familiar with the trade secrets, business
plans and business strategies and with other Confidential Information (as
defined on the Appendix hereto) concerning each of the Company and any
applicable Affiliate of the Company (and their respective predecessors,
successors and assigns) and that Executive's services have been and shall be of
special, unique and extraordinary value to the Company and any applicable
Affiliate of the Company. Therefore, Executive agrees that, during the period
from the beginning of the Employment Period through and including the date that
is the one-year anniversary of the last day of the Employment Period (such
period, the "Noncompete Period"), Executive shall not directly or indirectly
(whether for Executive or for any other Person) own any interest in, operate,
manage, control, engage in, participate in (whether as an officer, director,
employee, partner, agent, representative or otherwise), invest in, permit
Executive's name to be used by, consult with, advise, render services for (alone
or in association with any other Person), or otherwise assist in any manner (i)
any of International Data Group, Inc.; CMP Media, Inc. (a subsidiary of United
Business Media PLC); The Future Network Plc; CNET Networks, Inc.; MediaLive
International, Inc.; Penton Media, Inc.; Jupitermedia Corporation; Deutsche
Messe AG; or DMG World Media, (ii) any Person that engages in, or owns, invests
in, operates, manages or controls any venture or enterprise which directly or
indirectly engages or proposes to engage in, any business or enterprise which
manufactures, designs, produces, renders or sells products or services which
compete with the products and services of the Company and its Affiliates
(including, but not limited to, the Initial Events, Other Events, other events,
conferences or businesses of the Company or any of its Subsidiaries from which
TM Media Revenues are to be calculated, or any products, services, or events the
Company is in the process of developing), as the Company's and its Affiliates'
businesses existed at or at any time during the Employment Period and prior to
termination of the Noncompete Period (the "Restricted Enterprises"), or (iii)
any successor, assignee, subsidiary, division or Affiliate of any Listed Person
or Restricted Person, or (iv) any Person in which, to the Knowledge of
Executive, any Person listed in clause (i) or clause (ii) of this Section 5(a)
owns an interest or participates, which any Person listed in clause (i) or
clause (ii) of this Section 5(a) manages or controls (whether as an officer,
director, employee, partner, agent, representative or otherwise), or to which
any Person listed in clause (i) or clause (ii) of this Section 5(a) otherwise
provides management or financial support. Any Person listed in clause (i) of
this Section 5(a), or clause (iii) or clause (iv) of this Section 5(a) by virtue
of its relationship with a Person listed in clause (i) of this Section 5(a),
shall be referred to as a "Listed Person." Any Person listed in clause (ii) of
this Section 5(a), or clause (iii) or clause (iv) of this Section 5(a) by virtue
of its relationship with a Person listed in clause (ii) of this Section 5(a),
shall be referred to as a "Restricted Person." Notwithstanding the foregoing,
Executive may provide advice, services or assistance otherwise prohibited by
this Section 5(a) to a Restricted Person that is not a Listed Person, but solely
to the extent that any advice, services or assistance that Executive provides
for such Restricted Person that is not a Listed Person is not for the benefit
of, does not relate to, and is not in respect of, any of the Restricted
Enterprises of such Restricted Person that is not a Listed Person. Nothing
herein shall prohibit Executive from being an owner, indirectly through a mutual
fund or other similar pooled investment vehicle, of a passive investment in the
stock of a corporation which is publicly traded, so long as no TM Media
Principal has any other participation in the business of any such corporation.
The Company and Executive expressly acknowledge and agree that each and every
restriction imposed by this Section 5(a) is reasonable with respect to subject
matter, time period and geographical area.

      (b) Non-Solicitation. Executive agrees that during the Noncompete Period,
Executive shall not, and shall not permit any of his or her Affiliates to,
directly or indirectly through another Person (a) induce or attempt to induce
any employee of the Company or any Affiliate of the Company to leave the employ
of the Company or such Affiliate, or in any way interfere with the relationship
between the Company or any Affiliate of the Company and any employee thereof,
(b) hire any person who was an employee of the Company or any Affiliate of the
Company at any time during the 24 month period immediately preceding


                                       4
<PAGE>
                                  CONFIDENTIAL


the termination of the employment of Executive with the Company, (c) call on,
solicit or service any customer, supplier, licensee, licensor, franchisee or
other business relation of the Company or any Affiliate of the Company in order
to induce or attempt to induce such Person to cease or reduce doing business
with the Company or such Affiliate, or in any way interfere with the
relationship between any such customer, supplier, licensee or business relation
and the Company or any Affiliate of the Company, including, without limitation,
making any negative statements or communications about the Company or any of its
Affiliates, or (d) directly or indirectly acquire or attempt to acquire any
operating business in the United States of America to which the Company or any
of its Affiliates has made an acquisition proposal prior to the Termination Date
of Executive relating to the possible acquisition of such business (an
"Acquisition Target") by the Company or any of its Affiliates, or take any
action to induce or attempt to induce any Acquisition Target to consummate any
acquisition, investment or other similar transaction with any Person other than
the Company or any of the Company's Affiliates.

      (c) General. If the final judgment of a court of competent jurisdiction
declares that any term or provision of this Section 5 is invalid or
unenforceable, Executive agrees that the court making the determination of
invalidity or unenforceability shall have the power to reduce the scope,
duration, or area of the term or provision, to delete specific words or phrases,
or to replace any invalid or unenforceable term or provision with a term or
provision that is valid and enforceable and that comes closest to expressing the
intention of the invalid or unenforceable term or provision, and this Agreement
shall be enforceable as so modified after the expiration of the time within
which the judgment may be appealed. Because Executive's services are unique and
because Executive has access to Confidential Information and Work Product (as
defined on the Appendix hereto), the parties hereto agree that money damages
would not be an adequate remedy for any breach of this Agreement. Therefore, in
the event a breach or threatened breach of this Agreement, the Company or its
successors or assigns may, in addition to other rights and remedies existing in
their favor, apply to any court of competent jurisdiction for specific
performance and/or injunctive or other relief in order to enforce, or prevent
any violations of, the provisions hereof (without posting a bond or other
security). Executive agrees that the restrictions contained in Section 5 are
reasonable and that Executive has received consideration in exchange therefor.

      (d) Additional Services for the Company. In the event that, following
termination of the Employment Period, the Company or any of its Subsidiaries
engages Executive as an employee, consultant or advisor to the Company or any of
its Subsidiaries, no violation of Section 5(a) shall be deemed to result from
any post-termination employment, consulting or advisory services provided by the
Executive to or on behalf of the Company and its Subsidiaries in accordance with
the written instructions of, or the written employment, consulting or advisory
duties of Executive to, the Company or any of its Subsidiaries.

      (e) Termination of Non-Compete Obligations. Notwithstanding anything
herein to the contrary, the obligations of Executive pursuant to Section 5(a)
shall be terminated in the event that Executive is no longer employed by the
Company or any of its Affiliates and (i) any payment by the Company of any
portion of the Subsequent Purchase Price (as defined in the Stock Purchase
Agreement) then due and owing as determined pursuant to the Stock Purchase
Agreement is not paid when due and such default is not cured on or prior to the
30th day after written notice of such default is delivered by the Executive to
the Company, or (ii) in the event that any liquidation, dissolution or winding
up of Buyer, or any bankruptcy proceeding to which Buyer is party as debtor, is
consummated and, with respect to bankruptcy proceedings only, the obligations of
Buyer to pay any portion of the Subsequent Purchase Price are rejected or
reduced in connection therewith.

      6. Other Terms and Conditions. The terms and conditions set forth on the
Appendix attached hereto are incorporated herein by reference as if fully set
forth herein and constitute an integral part of this Agreement.

      3. General Provisions.

      (a) 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 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.

      (b) Complete Agreement. This Agreement constitutes the complete agreement
and understanding among the parties with respect to the subject matter hereof
and supersedes and preempts
<PAGE>
                                  CONFIDENTIAL


any prior understandings, agreements or representations by or among the parties,
written or oral, which relate to the subject matter hereof; provided that in no
event shall the Stock Purchase Agreement be deemed superseded or preempted by
this Agreement.

      (c) Counterparts; Signatures Received via Facsimile. This Agreement may be
executed in separate counterparts, each of which is deemed to be an original and
all of which taken together constitute one and the same agreement. Signatures
received via facsimile shall be deemed originals for all purposes.

      (d) Successors and Assigns. Except as otherwise provided herein, this
Agreement shall bind and inure to the benefit of and be enforceable by
Executive, the Company and their respective successors and assigns; provided
that the rights and obligations of the parties under this Agreement shall not be

      (e) GOVERNING LAW. THE CORPORATE LAW OF THE STATE OF DELAWARE WILL GOVERN
ALL ISSUES CONCERNING THE RELATIVE RIGHTS OF THE COMPANY AND ITS STOCKHOLDERS.
ALL OTHER ISSUES CONCERNING THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT GIVING EFFECT TO ANY
CHOICE OF LAW OR CONFLICT OF LAW PROVISION OR RULE (WHETHER OF THE STATE OF NEW
YORK OR ANY OTHER JURISDICTION) THAT WOULD CAUSE THE APPLICATION OF THE LAW OF
ANY JURISDICTION OTHER THAN THE STATE OF NEW YORK.

      (f) Jurisdiction. The state and federal courts located in New York County,
New York (the "Permitted Courts"), shall have sole and exclusive jurisdiction of
any dispute arising out of or related to this Agreement (including without
limitation allegations of the breach or attempted breach thereof) (a
"Proceeding"). Notwithstanding the foregoing, nothing in this paragraph alters
any agreement the parties may previously have made or may in the future make to
arbitrate disputes. Each of the parties hereby expressly consents to the
personal jurisdiction of each of the Permitted Courts with respect to any
Proceeding and waives any objection, whether on the grounds of venue, residence
or domicile or on the ground that the Proceeding has been brought in an
inconvenient forum, to any Proceeding brought in a Permitted Court. Executive
agrees that a final judgment of a Permitted Court in any Proceeding shall be
conclusive and binding upon Executive and may be enforced in other courts to
whose jurisdiction Executive or his or her assets is or may be subject, by suit
upon such judgment.

      (g) Remedies. Each of the parties to this Agreement shall be entitled to
enforce its rights under this Agreement specifically, to recover damages and
costs (including reasonable attorney's fees) caused by any breach of any
provision of this Agreement and to exercise all other rights existing in its
favor. The parties hereto agree and acknowledge that money damages would not be
an adequate remedy for any breach of the provisions of this Agreement and that
any party may in its sole discretion apply to any court of law or equity of
competent jurisdiction (without posting any bond or deposit) for specific
performance and/or other injunctive relief in order to enforce or prevent any
violations of the provisions of this Agreement.

      (h) Interpretation. The Article and Section headings used herein are for
convenience only and do not define, limit or construe the content of such
sections. The parties acknowledge that they are entering into this Agreement
after consulting with counsel and based upon equal bargaining power, with each
party having the ability to participate in its preparation. The terms of this
Agreement shall not be interpreted in favor of or against any party on account
of the draftsperson, but shall be interpreted solely for the purpose of fairly
effectuating the intent of the parties hereto.

      (i) Survival. The provisions set forth in Section 3(b), Section 4 and
Section 5 of the Agreement and the provisions set forth in this Appendix shall
survive and continue in full force and effect in accordance with their terms
