EXECUTION COPY
                               SERVICES AGREEMENT

     The parties to this Services Agreement (this "Agreement"), dated as of
April 5, 2000, are ZD Inc., a Delaware corporation ("ZD"), and Ziff Davis
Publishing Inc., a Delaware corporation ("Buyer").

     Pursuant to the Purchase Agreement among ZD, ZD Holdings (Europe) Ltd. and
Buyer, dated December 6, 1999 (the "Purchase Agreement"), Buyer has purchased
certain print publications (the "Buyer Publications") and other assets as
described in the Purchase Agreement (the "Business"). The Buyer Publications and
the Business exclude the Computer Shopper print publication, its various special
editions, including the edition published under the name eShopper, and any
successor publication thereto (collectively, the "Publication").

     Prior to the purchase of assets pursuant to the Purchase Agreement, ZD
provided to the Publication certain services described in Section 1 below
(collectively, the "Services");

     ZD now desires to retain Buyer to provide the Services to ZD for the
Publication, as ZD may request from time to time, and Buyer desires to provide
such Services to ZD for the Publication.

     NOW, THEREFORE, in consideration of the premises and mutual covenants and
obligations set forth herein, the parties hereto agree as follows:

     SECTION 1. PERFORMANCE OF SERVICES; BUDGET.
                -------------------------------

     (a) Subject to the terms and conditions of this Agreement, Buyer shall
perform for ZD the Services described on Schedule 1(a) attached hereto. As part
of the Services, ZD shall be entitled to receive the benefit of all contractual
arrangements which Buyer has in effect from time to time with third parties
which relate to the functions described in Schedule 1(a) hereto, including,
without limitation, the arrangements with Warner Publisher Services, for
distribution; Centrobe, for fulfillment services; and Direct
<PAGE>

Media, for list rental. Buyer shall also manage ZD's relationships under the
arrangements with R.R. Donnelley & Sons, for printing and Bowater Newsprint for
paper.

     (b) At least ninety (90) days prior to the end of each calendar year during
the Term (as defined in Section 5), representatives of Buyer and ZD will meet to
discuss and agree upon a budget for the following year for the Services to be
performed by Buyer.  Attached as Exhibit A is the budget for calendar year 2000,
which has been agreed to by the parties. ZD will provide Buyer with reasonable
detail as to the expected nature and extent of the Services desired to be used
and Buyer will provide ZD with projected costs of such Services based on ZD's
stated needs.  ZD may notify Buyer of any changes to the nature or extent of the
Services it desires to obtain during any budgeted year and Buyer will use its
commercially reasonable efforts to accommodate ZD's request for increased or
decreased use of the Services as specified by ZD.  Buyer shall promptly (to the
extent practicable) notify ZD of any material deviation from the budget and
shall make any changes reasonably requested by ZD to remedy such deviation.

     SECTION 2. FEES; PAYMENT.
                -------------

     (a) ZD shall pay to Buyer in exchange for the Services, the cost, both out-
of-pocket and an allocable portion (based on the allocation method described in
the following sentence) of overhead of such Services (collectively, the "Usage
Fees"), plus an annual payment of $5 million (such annual payment the "Annual
Fee").  The allocation method will be specified in Schedule 2 but revised from
time to time so as to not be any less favorable than the allocation method used
to charge Buyer's Publications for such Services. Buyer shall provide to ZD all
benefits of Buyer's third party arrangements such that the out of pocket costs
charged to ZD shall be the same per unit (or other comparable metric) amounts as
those applicable to the Buyer Publications.

                                       2
<PAGE>

     (b) The amounts payable for Services under this Agreement do not include
any amounts for sales, use or similar taxes. If any such taxes are found at any
time to be required to be paid, they will be added to the amounts payable by ZD
pursuant to this Agreement.

     (c) Buyer shall send an itemized monthly invoice, in a format mutually
agreed to by Buyer and ZD, to ZD for the Usage Fees resulting from Services
provided by Buyer during the previous month and for one-twelfth of the Annual
Fee for the ensuing month. Payment terms are net cash payable in full by ZD
within the later of thirty (30) days after receipt of the invoice or forty-five
(45) days after the end of such previous month (the "Payment Due Date"). A late
charge will be charged each month for any payments received by Buyer later than
this Payment Due Date, except for payments which ZD disputes in good faith. The
late charge will be determined by multiplying the outstanding balance by X/12
where (X) is the prime rate announced from time to time by the Bank of New York.

     (d) ZD shall have the right, on at least ten (10) days prior notice to
Buyer, to examine or appoint an independent certified public accountant, who
shall agree to hold all information confidential except in connection with any
claim for ZD reimbursement hereunder, to examine and audit, at its own expense,
not more than twice each calendar year, during normal business hours and for a
reasonable duration, the relevant records of Buyer relating to calculation of
the Usage Fees. If such audit uncovers an overpayment by ZD, Buyer shall
promptly reimburse ZD in the amount of such overpayment and if the overpayment
is five percent (5%) or greater of the amount that should properly have been
charge for such period, Buyer shall also promptly reimburse ZD for the
reasonable costs of such audit actually incurred by ZD.

     SECTION 3. DIRECTION AND CONTROL OF BUYER'S PERSONNEL.
                ------------------------------------------

     Buyer shall have the exclusive right to direct and control its employees
providing the Services under the terms of this Agreement, free of any
interference by

                                       3
<PAGE>

ZD (other than in respect of ZD's right, as the recipient of the Services, to
specify the nature of the Services desired to be performed and the right to
receive and approve strategies and materials created or to be distributed by
such employees, in each case, specifically for the Publication). All of Buyer's
personnel providing the Services herein shall be exclusively employees of Buyer
or its affiliates, and Buyer shall have the sole right to determine their
conditions of employment, their working hours, employment and vacation policies,
seniority, promotions and assignments. Buyer will be solely responsible for
compensation of such employees and for all withholding taxes, F.I.C.A. and
F.U.T.A. taxes, unemployment insurance, workmen's compensation, and any other
insurance and fringe benefits with respect to its employees. Buyer shall also
have the exclusive rights to hire and fire any such personnel.

     SECTION 4. SERVICES TO BE RENDERED CONSISTENT WITH PAST PRACTICES. During
                ------------------------------------------------------
the Term (as defined in Section 5), Buyer shall in all material respects render
the Services and otherwise assist ZD in connection with the Publication in a
manner and of a quality consistent with past practice prior to the closing under
the Purchase Agreement, including, among other things, providing the Services
for the Publication in all respects with the same level of care and expertise as
it provides similar service to the Buyer Publications.

     SECTION 5. TERM AND TERMINATION.
                --------------------

     (a) The term (the "Term") of this Agreement shall commence as of the date
hereof and, unless earlier terminated pursuant to this Section 5, shall end on
the third anniversary of the date hereof. Upon termination or expiration, all
rights and obligations of each party hereunder shall cease as of the date of
termination and any amounts owed by either party under this Agreement shall be
paid in full in accordance with Section 2(c).

     (b) ZD may terminate this Agreement on at least ninety (90) days prior
notice to Buyer for any reason or for no reason.

                                       4
<PAGE>

     (c) Either party may terminate this Agreement in the event that the other
party is in material breach of such other party's obligations under this
Agreement, unless such party is also in material breach of its obligations under
this Agreement, (i) if the defaulting party has not cured the breach within
fifteen (15) days after notice by the non-defaulting party specifying the nature
of the breach, or (ii) if the breach is not amenable to cure, then immediately
upon receipt of such notice by the defaulting party.

     (d) Either party may terminate this Agreement as permitted under Section 8
in the event of a force majeure that prevents or materially delays the
performance by the other party of its obligations under this Agreement.

     (e) Sections 6, 7, and 9 through 11 shall survive termination or expiration
of this Agreement. In addition, ZD's obligation to pay the Annual Fee until the
third anniversary of the date of the Agreement shall survive early termination
of this Agreement for any reason other than termination pursuant to Section 5(c)
due to a breach by Buyer.

     SECTION 6. INDEMNIFICATION.
                ---------------

     (a) Buyer, will, at its expense, promptly reform or correct any Services
which do not meet the requirements of this Agreement to the extent that such
errors were caused by Buyer, its equipment, its employees or agents. Buyer shall

requirements of this Agreement to the extent that such Services are due to
causes external to Buyer  or otherwise beyond Buyer's control.

     (b) Buyer agrees to indemnify and hold ZD and its affiliates, successors
and assigns harmless against and in respect of, and to pay any costs, damages,
claims, losses, settlements, deficiencies, expenses and liabilities arising from
(A) Buyer's failure to have all rights, licenses, and/or approvals necessary to
permit it to perform the Services and (B) the gross negligence or willful
misconduct of Buyer, its employees or its agents; and (ii) any breach by Buyer,
its employees or its agents of any of Buyer's

obligations hereunder.

     (c) ZD agrees to indemnify and hold Buyer and its affiliates, successors
and assigns harmless against and in respect of, and to pay any costs, damages,
claims, losses, settlements, deficiencies, expenses and liabilities arising from
(i) any breach by ZD, its employees or its agents of any of ZD's obligations
hereunder and (ii) any claims arising against Buyer relating to the Publication
provided such claims do not result from the negligence or willful misconduct of
Buyer, its employees or its agents.

     (d) The obligation of either party to provide indemnification under this
Agreement shall be contingent upon the party seeking indemnification (i)
providing the other party with prompt written notice of any claim for which
indemnification is sought and (ii) cooperating fully with the other party and,
so long as such other party acknowledges its obligations to indemnify the party
seeking indemnification for such claim, allowing the other party to control the
defense and settlement of such claim.  The party seeking indemnification may not
settle any such claim without the other party's prior consent, which consent
shall not be unreasonably withheld. The party seeking indemnification shall have
the right, at its own expense, to participate in the defense of any such claim.

its disclosure indicate that it is confidential or proprietary (which shall
include, without limitation, all circulation strategies and results for the
Publication) shall not be disclosed to any third party and shall be protected by
the recipient in the same manner and to the same degree that the recipient
protects its own confidential information. Such information will be disclosed
only to those employees of the recipient requiring access thereto in order to
perform the party's obligations under this Agreement (it being understood that
access in a manner consistent with past practice will be permitted) and

                                       6

Agreement.

of circumstances beyond its reasonable control including, but not limited to,
acts of God, fires, floods, wars, civil disturbances, sabotage, accidents, labor
disputes (whether or not the employees' demands are reasonable and within the
party's power to satisfy), governmental actions or transportation delays. Either
party may terminate this Agreement without any liability to the other party,
subject to Section 5(g), if such other party is substantially unable, as a
result of any circumstance set forth in this Section, to perform its obligations
under this Agreement for a continuous period of thirty (30) days or for thirty

                          TRANSITION SERVICES AGREEMENT

     This TRANSITION SERVICES AGREEMENT (this "Agreement") is made as of April
5, 2000, by and between Ziff Davis Media Inc., a Delaware corporation ("Buyer"),
and ZD Inc., a Delaware corporation ("Asset Seller").

                              W I T N E S S E T H:

     WHEREAS, pursuant to that certain Purchase Agreement, dated as of December
6, 1999 (the "Purchase Agreement"), by and among Asset Seller, Ziff-Davis
(Europe) Holdings, Inc. (the "Stock Seller," and together with the Asset Seller,
the "Sellers") and Buyer, Buyer purchased certain publishing assets and
companies of the Sellers;

     WHEREAS, in connection therewith, Buyer and Asset Seller desire that each
of Buyer and Asset Seller provide, or cause their respective wholly-owned direct
or indirect subsidiaries to provide, the other or such other's wholly-owned
direct or indirect subsidiaries, with certain transition services as set forth
herein (it being understood that the provision of certain other services by
Buyer on the one hand, and/or Asset Seller, on the other hand, is addressed in
other agreements executed and delivered as of the date hereof); and

     WHEREAS, capitalized terms used herein and not otherwise defined herein
have the meanings given to such terms in the Purchase Agreement;

     NOW, THEREFORE, in consideration of the premises and covenants set forth
herein and other good and valuable consideration, the receipt and sufficiency of
which is hereby acknowledged, Buyer and Asset Seller agree as follows:

     1.   Transition Services.

     (a) Subject to the other terms and conditions of this Agreement, each of
Buyer and Asset Seller shall provide, or shall cause its wholly-owned direct or
indirect subsidiaries to provide, to the other or wholly-owned direct or
indirect subsidiaries of the other, from the date of this Agreement and for the
period of time set forth on Attachment A with respect to each of the services,
the respective services set forth on Attachment A attached hereto and such other
transition assistance as may be mutually agreed by Buyer and Asset Seller
(collectively, the "Transition Services"). For purposes of this Agreement, each
party is referred to as a "Provider" in its capacity as the provider of a
Transition Service and as a "Recipient" in its capacity as the recipient of a
Transition Service.

     (b) Unless otherwise agreed, the Transition Services shall be provided at
Vendor Cost. For purposes of this Agreement, "Vendor Cost" means the amount
specified on Attachment A. In addition, "Vendor Cost" shall include the direct
out-of-pocket costs incurred by the Provider in providing the services, but only
to the extent that such direct out-of-pocket costs have not been
<PAGE>

included by the Provider in the amounts set forth on Attachment A. In addition,
unless otherwise specified on Attachment A, Asset Seller shall also pay to Buyer
any amounts that are required to be paid to any licensors of software that is
used in connection with the provision of any services hereunder, and any amounts
that are required to be paid to any such licensors to obtain the consent of such
licensors to provide any of the services hereunder. Subject to the immediately
preceding sentence, Buyer shall use reasonable efforts to obtain any consents
that may be required from such licensors in order to provide any of the services
hereunder.

     (c) Each Provider of Transition Services shall perform such Transition
Services exercising the same degree of care as it exercises in performing the
same or similar services for its own account, with priority equal to that
provided to its own businesses or those of any of its affiliates, subsidiaries
or divisions.

     2. Billing and Payment. With respect to each of the Transition Services,
the Recipient shall pay to the Provider the monthly charge or other charge
specified on Attachment A for each Transition Service by the last day of each
calendar month during the Transition Period. The Recipient shall promptly pay

any third party for any special, consequential or exemplary damages (including
lost or anticipated revenues or profits relating to the same) arising from any

the person of such parties and over the subject matter of such dispute and agree

other manner as may be permitted by law, shall be valid and sufficient service

     (b) Each party hereto hereby acknowledges and agrees that any controversy
which may arise under this agreement is likely to involve complicated and
difficult issues, and therefore each such party hereby irrevocably and
unconditionally waives any right such party may have to a trial by jury in
respect of any litigation directly or indirectly arising out of or relating to

certifies and acknowledges that (i) no representative, agent or attorney of any

          compensate the applicable Provider for the benefits and other costs
          incurred by such Provider with respect to such persons. The Recipient
          shall have no liability with respect to any severance, vacation,
          termination, pension, profit sharing or other employee benefits that
          may be payable to any Covered Person of the Provider.

     C.   Duration. Each Provider shall use commercially reasonable efforts to
          have available the Covered Persons to continue providing the
          applicable services to the Recipient until December 31, 2000, or such
          earlier date as the Recipient may specify in writing to the applicable
          Provider with respect to each Covered Person with 30 days prior
          written notice.

8.   Continued Health Insurance Coverage.

     A.   Services; Duration; Charges. For the period beginning on the Closing
          Date and continuing for the remainder of the calendar month in which

          Buyer provides Asset Seller with notice by April 14 of an earlier
          termination in which case it shall be until April 30, 2000), Asset
          Seller shall provide to the Transferred Employees the same medical
          coverage under Asset Seller's Aetna's ASA medical plan that was
          provided to such employees by Asset Seller immediately before Closing.
          Buyer shall pay Asset Seller the amount of $220,000 per month for each
          month as total compensation for such coverage, payable promptly after
          this date with respect to April and on May 1 if not cancelled as

                                   Schedule 1

Accounts Receivable

Cash receipts into the lockbox accounts maintained by Asset Seller will be
posted to the Accounts Receivable ledger by the A/R department of Buyer (led by
Beverly Lewis). Once Asset Seller has established its own A/R department,
Buyer's team will provide reasonable assistance in transitioning to Asset Seller
the process of monitoring Asset Seller's lockbox accounts and posting receipts
to Asset Seller's Accounts Receivable ledger. Such transition shall occur as
soon as practicable, but in any event no later than June 1, 2000.

The majority of the existing lockbox accounts of Asset Seller will remain with
Asset Seller. Buyer's A/R department will continue to process receivables
ensuring the appropriate split between Asset Seller and Buyer. The cash received
in the lockbox accounts will be distributed to the appropriate bank accounts
(i.e., Asset Seller or Buyer).

Once Asset Seller's personnel have taken over receivable management and review
of the daily lockbox receipts for Asset Seller's lockbox accounts, Asset Seller
shall promptly remit (within 1 business day of receipt) all collections in
respect of payments made to Buyer.

If during the period that Buyer's personnel are managing Asset Seller's lockbox
accounts or the period that Asset Seller's personnel are managing such lockbox
accounts, any payment is received from a customer who purchases products or
services from both Buyer and Asset Seller without specification as to which
invoice such payment relates, the following procedures shall be implemented to
determine which party (Buyer or Asset Seller) is entitled to the benefit of such
payment:

     o    Contact the customer for specifics as to what invoices and what
          company is being paid (this should be performed by the personnel
          managing the lockbox (i.e. Buyer in the early transition and Asset
          Seller in the later transition). A written indication (fax or e-mail)
          should be requested from the customer to alleviate potential future
          collection issues.

     o    If specifics are not available from the customer, the cash should be
          applied to the oldest invoices of Buyer or Asset Seller and ratably to
          any invoices which are the same aging.

Cash Disbursements

Cash disbursements are made primarily through accounts payable processing and
wire transfers. Wire transfers are discussed under Management of Daily Cash
Position.

Buyer shall continue to process Asset Seller's accounts payable through April
30, 2000, at which time Asset Seller's personnel will take over the processing
of Asset Seller's accounts payables. Accounts payable for Asset Seller will
continue to be processed out of the Delaware checking
<PAGE>

account. Buyer will be permitted to continue to use Asset Seller's Delaware
checking account to process its disbursements on a transitional basis until
April 30, 2000. During the period that Buyer and Asset Seller are using the same
Delaware checking account for accounts payable processing, the account will be
funded by Asset Seller's concentration account (this is how the "mechanics" are
set at the bank) and Buyer will reimburse Asset Seller's concentration account
(from Buyer's concentration account).

Such reimbursement will be done at the time of a check run. A separate business
unit A/P will be set up to process Buyer's A/P. In this manner at the time of
cutting checks, the parties will know which checks relate to Buyer and which
relate to Asset Seller. Before checks are mailed in respect of Buyer's A/P,
Buyer will fund Asset Seller's concentration account in respect of such
payments.

Management of Daily Cash Position

Managing the daily cash position includes, managing overnight investing of cash
and repayment of debt with excess cash.

Wire transfers are currently processed by Val Estrada and approved by either
Mark Moyer or Tom Wright. Prior to Closing, Asset Seller needs to set up
authorization for wire approval with an authorized representative of Asset
Seller. Such wires are processed out of Asset Seller's concentration account and
primarily relate to debt payments. Wires are currently approved through the Bank
of NY software system installed at Buyer. On a daily basis, Val Estrada prepares
a G/L upload file to record the day's wire activities in the G/L.

While Asset Seller works to train new users and to have the software installed
locally, Buyer will continue to provide this service. The parties may establish
a system of e-mail authorization to indicate wire transfers are made in
accordance with Asset Seller's instructions. Once Asset Seller has the software
installed and employees trained, it will take over the process of setting up the
wires for approval and preparing the G/L upload file (until 6/30/00, the file
will be uploaded to Buyer's PeopleSoft system). Such takeover of the process
shall occur no later than June 30, 2000.

Timing

Based on the above, Asset Seller's and Buyer's banking systems should be
operating separately no later than May 1, 2000. Asset Seller may continue to use
the links to Buyer's PeopleSoft system so accounting services can be provided
(i.e. ensure proper G/L posting of all cash transactions) through June 30, 2000
(in accordance with paragraph 2A of Attachment A).

                                   Schedule 2

Buyer agrees to provide continued support for users from each of the
organizations listed below of infrastructure, core business applications, and
departmental systems, being acquired by Buyer pursuant to the Purchase
Agreement, for the periods listed below. Services will be rendered on a monthly
charge-back basis (where applicable) throughout the transition period.
Charge-back fees will be calculated as described on the schedule included below.
The following sections outline the support to be provided for each organization.
In all cases the dates provided are projected based on requirements expressed by
the supported organizations. In each case the purpose of this service agreement
is to facilitate the smooth transition of existing Ziff-Davis Inc.
organizational components from an integrated centrally serviced group to
autonomous businesses each capable of sustaining operations independently. As
each business unit is able to transition to its own information systems
infrastructure the services provided by Buyer will be terminated. Accordingly,
the contents of this Schedule 2 form a framework that will be used to guide
activities between Buyer and other business components throughout the transition
period. Modifications will be negotiated as required due to operational
considerations within the spirit of this Schedule 2.

The information systems strategy for Buyer consists of migration of applications
from their current operational environment. The current applications platform
will remain in place (supported by Buyer) through the periods described below.
Supported organizations will require no change to their existing client
environment throughout this period. In any case where an organization requires
support after the dates provided, such support will be provided, however
additional costs may be incurred associated with changes in technology required
within the new applications environment of Buyer. These additional costs would
be passed directly through to the organizations(s) receiving such services.

Lotus Notes Environment

Ziff Davis Publishing has begun the process of transitioning support for Lotus
Notes to Interliant, an external service provider. This transition project
involves an overall upgrade and consolidation of Publishing Lotus Notes servers,
upgrade of the Lotus Notes server software to version 5.0, and implementation of
a hierarchical addressing scheme. A copy of the Interliant project proposal has
been provided to ZDNet, ZDTV, and ZD Events for review. The primary Lotus Notes
asset acquired by Buyer in this area is the Lotus Notes Certificate (i.e. naming
convention) for the current Notes implementation. Accordingly, each separate
business entity (ZDNet, ZDTV, etc.) will be required to procure their own Lotus
Notes Certificate to continue operating Lotus Notes following the transition
period. However, the application implementations that have been developed with
Lotus Notes (Sales Territory Database etc.) are not controlled by any license
agreement and are considered shared. Accordingly, copies of the required
applications with associated data will be provided to each business organization
as part of their transition to their own Lotus Notes environment.

In regards to Lotus Notes Mail each organization will be developing an
addressing scheme independent of the current shared FirstName_LastName@ZD.COM
convention. For a period of time following separation, the service of forwarding
Internet e-mail addressed via ZD.COM will be required. During the transition
period continued routing of this e-mail will be maintained as is by the
Publishing Notes service provider. However, the ZD.COM domain name has not been
acquired by Buyer. Consequently, the service of providing internet e-mail
forwarding via this address, and related "new address notification", will
necessarily revert to the remaining company following the transition of
Publishing on or before June 30, 2000.

Throughout the transition period (projected through 30 June 2000) there will be
no charges for continued use of the existing Lotus Notes Certificate, e-mail, or
applications. In addition, Publishing will continue to share all information
regarding Interliant and the outsourcing of Notes support as an alternative to
be considered by each organization.

Charge-back Schedules

Wide Area Network -- Charges are based on connections supported and the number
of users within each organization. As each organization migrates to their own
WAN network charges for remaining organizations will not change. All charges
computed for WAN usage will be handled as a direct pass through and will be
reviewed with representatives of Asset Seller.

Core Business Applications -- Charge-back for core business applications
(PeopleSoft HR, PeopleSoft Accounting, ADSCOPE and ADMARC) will be based on the
following criteria. In each

                                       -2-
<PAGE>

case the schedule reflects only that cost associated with continued support of
these applications in their current configuration through the transition period.
On a monthly basis a detailed breakdown of operating cost for each application
will be provided in support of the charge-back fee. In addition, services
provided by the ZDNet and the ZD Inc. transition team that support the
Publishing transition will be deducted from monthly charge-back fees.

PeopleSoft Accounting - Charge-back for this application will be calculated
based on the percentage of the total number of AP invoices/GL line item
transactions processed by each user organization during a given month and
therefore will vary according to actual use.

PeopleSoft HR - Charge-back for this application will be calculated based on the
percentage of the total number of employees actively supported within the
application represented by each user organization during a given month and
therefore will vary according to employee count.

ADMARC - Charge-back for this application will be calculated based on the number
of ZDNet Active users as a percentage of the total actively supported users
within the application. The only organization affected is ZDNet with
approximately five current users as compared to approximately eighty for
Publishing. The Product Index application is considered a part of ADMARC within
this agreement.

ADSCOPE - Charge-back for this application will be calculated based on the
number of ZDNet Active users as a percentage of the total actively supported
users within the application. The only organization affected is ZDNet. These
calculations will take into account any external costs for licensing as well as
internal costs for support personnel as required.

Transition Support

The Publishing division has initiated projects to migrate all of these
applications to a new platform supported by an external service provider (Ciber,
Inc.). The cost of this transition project will not be included in calculations
of charge-back to supported organizations. In addition, Publishing will provide
all information related to Ciber for consideration by supported organizations,
as a possible service provider for their long term needs.
