anniversary of the date hereof and (ii) one-year anniversary of the Termination
Date if Executive's employment is so terminated after the second anniversary of
the Employment Period and prior to the expiration of the Employment Period.
Each severance payment hereunder shall be payable in accordance with
Publishing's normal payroll procedures and cycles and shall be subject to
withholding of applicable taxes and governmental charges in accordance with
federal and state law. After payment of the severance amounts described in this
Section 4(d), Publishing shall have no obligation to make any further severance
or other payment to or on behalf of Executive except as otherwise expressly
contemplated hereby. Notwithstanding the foregoing, in the event that Executive
shall breach any of Executive's obligations under Sections 5, 6 or 7 of this
Agreement, then, in addition to any other rights that Publishing may have under
this Agreement or otherwise, Publishing 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.  Confidential Information.  Executive acknowledges that by reason of
Executive's duties to and association with the Publishing and its Affiliates,
Executive has had and will have access to and has and will

                                      2

<PAGE>

become informed of Confidential Information (as defined in Section 9 below)
which is a competitive asset of Publishing and/or its Affiliates. Executive
agrees to keep in strict confidence and not, directly or indirectly, make
known, disclose, furnish, make available or use, any Confidential Information,
except for use in Executive's regular authorized duties on behalf of Publishing
and its Affiliates. Executive acknowledges that all documents and other
property including or reflecting Confidential Information furnished to
Executive by Publishing or any of its Affiliates or otherwise acquired or
developed by Publishing or any of its Affiliates or Executive or known by
Executive shall at all times be the property of the Publishing and its
Affiliates. Executive shall take all necessary and appropriate steps to
safeguard Confidential Information and protect it against disclosure,
misappropriation, misuse, loss and theft. Executive shall deliver to Publishing
at the termination of the Employment Period, or at any other time Publishing
may request, all memoranda, notes, plans, records, reports, computer tapes,
printouts and software and other documents and data (and copies thereof)
relating to the Confidential Information, Work Product (as defined in Section 9
below) or the business of Publishing or any of its Affiliates which Executive
may then possess or have under Executive's control.

   6.   Inventions and Patents.

   (a) Executive acknowledges that all Work Product (as defined in Section 9
below) is the exclusive property of Publishing. Executive hereby assigns all
right, title and interest in and to all Work Product to Publishing. Any
copyrightable works that fall within the Work Product will be deemed "works
made for hire" under Section 201(b) of the 1976 Copyright Act, and Publishing
shall own all of the rights comprised in the copyright therein; provided,
however, that to the extent such works may not, by operation of law, constitute
"works made for hire," Executive hereby assigns to Publishing all right, title
and interest therein.

   (b) Executive shall promptly and fully disclose all Work Product to
Publishing and shall cooperate and perform all actions reasonably requested by
Publishing (whether during or after the Employment Period) to establish,
confirm and protect Publishing's right, title and interest in such Work
Product. Without limiting the generality of the foregoing, Executive agrees to
assist Publishing, at Publishing's expense, to secure Publishing's rights in
the Work Product in any and all countries, including the execution of all
applications and all other instruments and documents which Publishing shall
deem necessary in order to apply for and obtain rights in such Work Product and
in order to assign and convey to Publishing the sole and exclusive right, title
and interest in and to such Work Product. If Publishing is unable because of
Executive's mental or physical incapacity or for any other reason (including
Executive's refusal to do so after request therefor is made by Publishing) to
secure Executive's signature to apply for or to pursue any application for any
United States or foreign patents or copyright registrations covering Work
Product belonging to or assigned to Publishing pursuant to paragraph 6(a)
above, then Executive hereby irrevocably designates and appoints Publishing and
its duly authorized officers and agents as Executive's agent and
attorney-in-fact to act for and in Executive's behalf and stead to execute and
file any such applications and to do all other lawfully permitted acts to
further the prosecution and issuance of patents or copyright registrations
thereon with the same legal force and effect as if executed by Executive.
Executive agrees not to apply for or pursue any application for any United
States or foreign patents or copyright registrations covering any Work Product
other than pursuant to this paragraph in circumstances where such patents or
copyright registrations are or have been or are required to be assigned to
Publishing.

   7.  Non-Compete, Non-Solicitation.

   (a) In further consideration of the compensation to be paid to Executive
hereunder, Executive acknowledges that in the course of Executive's employment
with the Publishing and its Affiliates, he has prior to the date of this
Agreement, and will during the Employment Period, become familiar with
Publishing's and its Affiliates' (and their predecessors') trade secrets,
business plans and business strategies and with other Confidential Information
concerning Publishing and its predecessors and its Affiliates and that
Executive's services have been and shall be of special, unique and
extraordinary value to the Publishing and its Affiliates. Therefore, Executive
agrees that, during the Employment Period and for a period of 18 months
thereafter (such period, the "Noncompete Period"), Executive shall not directly
or indirectly own any interest in, manage, control, participate in (whether as
an officer, director, employee, partner, agent, representative or otherwise),
consult

                                      3

<PAGE>

with, render services for, or in any other manner engage in, any of the
businesses (i) of International Data Group, Inc., CMP Media, Inc. (a subsidiary
of United News & Media PLC), or CNET Networks, Inc. (the "Restricted Persons"),
(ii) of any successor, assignee, partner, joint venture or collaboration
partner, subsidiary, division or Affiliate of any of the Restricted Persons, or
(iii) in which any of the Restricted Persons owns an interest or participates,
which any of the Restricted Persons manages or controls (whether as an officer,
director, employee, partner, agent, representative or otherwise), or with which
any of the Restricted Persons consults or to which any of the Restricted
Persons otherwise provides management or financial support. 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 Executive has no
other participation in the business of any such corporation.

   (b) During the Employment Period and for a period of 18 months thereafter,
Executive shall not directly or indirectly through another Person (i) induce or
attempt to induce any employee of Publishing or any Affiliate to leave the
employ of Publishing or such Affiliate, or in any way interfere with the
relationship between Publishing or any Affiliate and any employee thereof, (ii)
hire any person who was an employee of Publishing or any Affiliate at any time
during the one year period prior to the termination of the Employment Period,
(iii) call on, solicit or service any customer, supplier, licensee, licensor,
franchisee or other business relation of Publishing or any Affiliate in order
to induce or attempt to induce such Person to cease or reduce doing business
with Publishing or such Affiliate, or in any way interfere with the
relationship between any such customer, supplier, licensee or business relation
and Publishing or any Affiliate (including, without limitation, making any
negative statements or communications about Publishing or its Affiliates) or
(iv) directly or indirectly acquire or attempt to acquire any business in the
United States of America to which Publishing or any of its Affiliates has made
an acquisition proposal prior to the Termination Date relating to the possible
acquisition of such business (an "Acquisition Target") by Publishing 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 Publishing or any of its Affiliates.

   8.  Enforcement.  If, at the time of enforcement of Sections 5, 6 or 7 of
this Agreement, a court shall hold that the duration, scope, or area
restrictions stated herein are unreasonable under circumstances then existing,
the parties hereto agree that the maximum period, scope or geographical area
reason-able under such circumstances shall be substituted for the stated
period, scope or area and that the court shall be allowed and directed to
revise the restrictions contained herein to cover the maximum period, scope and
area permitted by law. Because Executive's services are unique and because
Executive has access to Confidential Information and Work Product, 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, Publishing 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). In addition, in the event of an
alleged breach or violation by Executive of Section 7, the Period set forth in
such Section shall be tolled until such breach or violation has been duly
cured. Executive agrees that the restrictions contained in Section 7 are
reason-able and that Executive has received consideration in exchange therefor.
