                                    SERVICES

         2.1      SERVICES.

                  (a)     INITIAL SERVICES. Except as otherwise provided herein,
for the term determined pursuant to Section 2.2 hereof, Providing Company shall
provide or cause to be provided to Receiving Company, in each case as identified
in the Exhibits attached hereto, the following "Initial Services":

                           (i) DATA PROCESSING SERVICES described in Exhibits
         DP-1 through DP-3;

                           (ii) TELECOMMUNICATIONS SERVICES described in
         Exhibits TC-1 through TC-32;

                           (iii) CORPORATE SUPPORT SERVICES described in
         Exhibits CS-1 (CFO) through CS-24 (CFO); CS-100 (HR) through CS-165
         (HR); CS-201 (GPO) through CS-202 (GPO); CS-301(GRE) through CS-303
         (GRE); CS-401 (L&GA) through CS- 411 (L&GA); CS-501 (CIO) through CS-
         543 (CIO); CS-701 (BL) through CS- 712 (BL); and CS-801 (GEN) through
         CS-802 (GEN), as more fully identified in the list preceding each
         series of Exhibits hereto; and

                           (iv) SYSTEMS REPLICATION AND TRANSFER SERVICES
         described in Exhibits SR-1 (CFO, CIO) through SR-8 (CFO, CIO).

                  (b)      ADDITIONAL SERVICES.

                           (i) From time to time after the Distribution Date,
         the parties may identify additional services that one party will
         provide to the other party in accordance with the terms of this
         Agreement (the "Additional Services" and, together with the Initial
         Services, the "Services"). The parties shall create an Exhibit for each
         Additional Service setting forth the identities of Providing Company
         and Receiving Company, a description of the Service, the time period
         during which the Service will be provided, the charge, if any, for the
         Service and any other terms applicable thereto and obtain the approval
         of each party's Representative. Except as set forth in Section
         2.1(b)(ii), the parties may, but shall not be required to, agree on
         Additional Services during the term of this Agreement.

                           (ii) Except as set forth in the next sentence,
         Providing Company shall be obligated to perform, at charges established
         pursuant to Section 2.3(b), any Additional Service that: (A) was
         provided by Providing Company immediately prior to the Effective Date
         and that Receiving Company reasonably believes was inadvertently or


                                      -3-
<PAGE>   6
         unintentionally omitted from the list of Initial Services or (B) is
         essential to effectuate an orderly transition under the Contribution
         and Distribution Agreement unless such performance would significantly
         disrupt Providing Company's operations or materially increase the scope
         of its responsibility under this Agreement. If Providing Company
         reasonably believes the performance of Additional Services required
         under (A) or (B) of the immediately preceding sentence would
         significantly disrupt its operations or materially increase the scope
         of its responsibility under this Agreement, Providing Company and
         Receiving Company shall negotiate in good faith to establish terms
         under which Providing Company can provide such Additional Services, but
         Providing Company shall not be obligated to provide such Additional
         Services if, the following good faith negotiation, it is unable to
         reach agreement on such terms.

                  (c)      SERVICES PERFORMED BY OTHERS. At its option,
Providing Company may cause any Service it is required to provide hereunder to
be provided by another member of its Group or by any other Person that is
providing, or may from time to time provide, the same or similar services for
Providing Company. Providing Company shall remain responsible, in accordance
with the terms of this Agreement, for performance of any Service it causes to be
so provided.

         2.2      TERM.

                  The term of this Agreement shall commence on the Effective
Date and shall remain in effect through March 31, 2001 ("Expiration Date"),
unless earlier terminated in accordance with Section 2.7 ("Termination Date").
This Agreement may be extended by the parties in writing either in whole or with
respect to one or more of the Services, provided, however, that such extension
shall only apply to the Service for which the Agreement was extended. The
parties shall be deemed to have extended this Agreement with respect to a
specific Service if the Exhibit for such Service specifies a completion date
beyond the Expiration Date. The parties may agree on an earlier expiration date
with respect to a specific Service by specifying such earlier date on the
Exhibit for that Service. Services shall be provided up to and including the
date set forth in the applicable Exhibit, subject to earlier termination as
provided herein.

         2.3      CHARGES AND PAYMENT.

                  (a)      CHARGES FOR INITIAL SERVICES. Receiving Company shall
pay Providing Company the charges, if any, set forth on the Exhibit for each of
the Services listed therein as adjusted, from time to time, in accordance with
the process and procedures established under Section 2.3(f) hereof. Wherever
practical, charges shall be based on the actual incurred costs, not budgeted or
estimated costs. The parties also intend for charges to be easy to administer
and justify and, therefore, they hereby acknowledge it may be counterproductive
to try to recover every cost, charge or expense particularly those that are
insignificant or de minimis. The parties shall use good faith efforts to discuss
any situation in which the actual charge for a Service is reasonably expected to
exceed the estimated charge, if any, set forth on an Exhibit for a particular
Service, provided, however, that the incurrence of charges in excess of any such


                                      -4-
<PAGE>   7
estimate shall not justify stopping the provision of, or payment for, Services
under this Agreement.

                           (i) In the case of Data Processing Services,
         Telecommunications Services or Common Support Services, except as
         otherwise set forth in an Exhibit for a specific Service, the parties
         intend for these charges to allow Providing Company to recover the
         fully allocated direct costs of providing such Services plus all
         out-of-pocket, third party costs, charges or expenses, but without any
         profit. Where the number of employees assigned by each party to jointly
         support an Initial Service is in proportion to the parties' historical
         or expected use of such Initial Service, and each party is responsible
         for the costs and expenses of its employees so assigned, recovery may
         be limited to other direct costs, such as data processing and software
         license fees.

                           (ii) In the case of Systems Replication and Transfer
         Services, except as otherwise set forth in an Exhibit for a specific
         Service, the parties intend that costs and expenses associated with
         isolating, separating or replicating a System be borne by the parties
         in proportion to their usage of the System prior to the Effective Date.
         To the extent not otherwise determined prior to the Effective Date, the
         parties shall determine the appropriate proportion of each party for
         each Systems Replication and Transfer Service prior to the Distribution
         Date. Where the number of employees assigned by each party to jointly
         replicate or transfer a System is in proportion to the parties'
         historical or expected use of such System, and each party is
         responsible for the costs of its employees so assigned, recovery may be
         limited to other direct costs such as third party contractor fees or
         extraordinary data processing or networking costs. For purposes of the
         foregoing, the parties acknowledge that, unless otherwise agreed in
         writing, the costs of buying new hardware or obtaining new software
         licenses shall be the responsibility of the party purchasing such
         hardware or licensing such software.

                  (b)      CHARGES FOR ADDITIONAL SERVICES. Receiving Company
shall pay Providing Company the charges, if any, set forth on each Exhibit
hereafter created for each of the Additional Services listed therein. Except for
Systems Replication and Transfer Services required by Section 2.1(b)(ii), costs
and expenses associated with System Replication and Transfer Additional Services
shall be borne by the party requesting such Additional Services. Charges, if
any, for other Additional Services, including those required by Section
2.1(b)(ii), shall be determined according to methods in use prior to the
Effective Date or such other method as may be mutually agreed that ensures that
Providing Company recovers costs and expenses, but without any profit, in
accordance with Section 2.3(a). Notwithstanding the foregoing, however, the
agreement of a party to provide or receive any Additional Service that is not
required pursuant to Section 2.1(b)(ii) at any given rate or charge shall be at
the sole discretion of such party.

                  (c)      PAYMENT TERMS. Providing Company shall bill Receiving
Company monthly for all charges pursuant to this Agreement. Such bills shall be
accompanied by reasonable documentation or other reasonable explanation
supporting such charges. Receiving Company shall pay Providing Company for all
Services provided hereunder within thirty (30)


                                      -5-
<PAGE>   8
days after receipt of an invoice therefor. Late payments shall bear interest at
the Prime Rate plus two percent (2%) per annum.

                  (d)      PERFORMANCE UNDER ANCILLARY AGREEMENTS.
Notwithstanding anything to the contrary contained herein, Receiving Company
shall not be charged under this Agreement for any Services that are specifically
required to be performed under the Contribution and Distribution Agreement or
any other Ancillary Agreement and any such other Services shall be performed and
charged for in accordance with the terms of the Contribution and Distribution
Agreement or such other Ancillary Agreement.

                  (e)      RECORDS. As needed from time to time during the
period during which Services are provided, and upon termination of the provision
of any Services, the parties agree to provide each other with records (in any
format, electronic or otherwise) related to the provision of Services under this
Agreement to the extent that (i) such records exist in the ordinary course, (ii)
do not involve the incurrence of any material expense and (iii) are reasonably
necessary by any such party to comply with its obligations hereunder or under
applicable law.

                  (f)      PRICING ADJUSTMENTS. In the even of a tax audit
adjustment relating to the pricing of any or all Services provided pursuant to
this Agreement in which it is determined by a taxing authority that any of the
charges, individually or in combination, did not result in an arm's-length
payment, as determined under internationally accepted arm's-length standards,
then the parties, including a Providing Company subcontractor or a member of
Providing Company's Group providing or receiving Services hereunder, may agree
to make corresponding adjustment to the charges in question for such period to
the extent necessary to achieve arm's-length pricing. Any adjustment made
pursuant to this Section 2.3(f) shall be reflected in the parties' official
books and records, and the resulting overpayment or underpayment shall create an
obligation to be paid in the manner specified in Section 2.3(c).

         2.4      GENERAL OBLIGATIONS; STANDARD OF CARE.

                  (a)      PERFORMANCE METRICS: PROVIDING COMPANY. Subject to
Section 2.5(c), Providing Company shall maintain sufficient resources to perform
its obligations hereunder. Specific performance metrics for Providing Company
may be set forth in Exhibits. Where none is set forth for Data Processing
Services, Telecommunications Services and Common Support Services, Providing
Company shall use reasonable efforts to provide Services in accordance with the
policies, procedures and practices in effect before the date hereof and shall
exercise the same care and skill as it exercises in performing similar services
for itself. Where none is set forth for System Replication and Transfer
Services, Providing Company will use reasonable efforts to replicate and
transfer each System so that is has substantially the same functionality for
Receiving Company as it did immediately before the date hereof taking into
account changes reasonably expected and customary in a new operating
environment.

                  (b)      PERFORMANCE METRICS: RECEIVING COMPANY. Specific
performance metrics for Receiving Company may be set forth in Exhibits. Where
none is set forth, Receiving Company shall use reasonable efforts, in connection
with receiving Services, to follow the


                                      -6-
<PAGE>   9
policies, procedures and practices in effect before the date hereof including
providing information and documentation sufficient for Providing Company to
perform the Services as they were performed before the date hereof and making
available, as reasonably requested by Providing Company, sufficient resources
and timely decisions, approvals and acceptances in order that Providing Company
may accomplish its obligations hereunder in a timely manner.

                  (c)      TRANSITIONAL NATURE OF SERVICES; CHANGES. The parties
acknowledge the transitional nature of the Services and that Providing Company
may make changes from time to time in the manner of performing the Services if
Providing Company is making similar changes in performing similar services for
members of its own Group and if Providing Company furnishes to Receiving Company
substantially the same notice Providing Company shall provide members of its own
Group respecting such changes. Notwithstanding the foregoing, between the date
hereof and March 31, 2001, Providing Company will not make any material change
to Systems affecting Receiving Company without first providing thirty (30) days
prior written notice and obtaining Receiving Company's prior written consent,
which consent shall not be unreasonably withheld or delayed.

                  (d)      RESPONSIBILITY FOR ERRORS; DELAYS. Providing
Company's sole responsibility to Receiving Company:

                           (i) for errors or omissions in Data Processing
         Services, Telecommunications Services and Common Support Services,
         shall be to furnish correct information, payment and/or adjustment in
         the Services, at no additional cost or expense to Receiving Company;
         provided, Receiving Company must promptly advise Providing Company of
         any such error or omission of which it becomes aware after having used
         reasonable efforts to detect any such errors or omissions in accordance
         with the standard of care set forth in Section 2.4(b);

                           (ii) for failure to deliver any Data Processing
         Service, Telecommunications Service or Common Support Service because
         of Impracticability, shall be to use reasonable efforts, subject to
         Section 2.5(c), to make the Services available and/or to resume
         performing the Services as promptly as reasonably practicable;

                           (iii) for an error, bug, fault or deficiency in a
         replicated or transferred System (a "System Error") shall be to use
         reasonable efforts, subject to Section 2.5(c) and taking into account
         the importance of the affected System to Receiving Company's business
         operations, to cooperate with Receiving Company to correct such System
         Error at no additional cost or expense to Receiving Company (such
         correction may take the form of new or revised software or an
         appropriate work-around); provided, Receiving Company must advise
         Providing Company of any such System Error within sixty (60) days after
         completion of the activities set forth in (A) the Exhibit for the
         System containing a System Error or (B) the Exhibit for any feeder
         System that caused the System Error, whichever is later;

                           (iv) for failure to complete any of the Systems
         Replication or Transfer Services because of Impracticability, shall be
         to use reasonable efforts, subject to Section 2.5(c), to make the
         Systems available to Receiving Company from a Providing Company
         facility until Providing Company can resume replication or transfer
         activities or until the parties devise an appropriate alternative
         approach pursuant to Section 2.4(f).

                  (e)      GOOD FAITH COOPERATION; CONSENTS. The parties will
use good faith efforts to cooperate with each other in all matters relating to
the provision and receipt of Services. Such cooperation shall include exchanging
information, providing electronic access to Systems used in connection with
Services, performing true-ups and adjustments and obtaining all consents,
licenses, sublicenses or approvals necessary to permit each party to perform its
obligations hereunder. The costs of obtaining such consents, licenses,
sublicenses or approvals shall be allocated in accordance with Section 2.3(a).
The parties will maintain documentation supporting the information contained in
the Exhibits and cooperate with each other in making such information available
as needed in the event of a tax audit, whether in the United States or any other
country.

                  (f)      ALTERNATIVES. If Providing Company reasonably
believes it is unable to provide any Service because of a failure to obtain
necessary consents, licenses, sublicenses or approvals pursuant to Section
2.4(e) or because of Impracticability, the parties shall cooperate to determine
the best alternative approach. Until such alternative approach is found or the
problem otherwise resolved to the satisfaction of the parties, the Providing
party shall use reasonable efforts, subject to Sections 2.5(b) and 2.5(c), to
continue providing the Service or, in the case of Systems, to support the
function to which the System relates or permit Receiving Company to have access
to the System so Receiving Company can support the function itself. To the
extent an agreed upon alternative approach requires payment above and beyond
that which is included in Providing Company's charge for the Services in
question, the parties shall share equally in making any such payment unless they
otherwise agree in writing.

         2.5      CERTAIN LIMITATIONS.

                  (a)      SERVICE BOUNDARIES. Except as provided in an Exhibit
for a specific Service: (i) Providing Company shall be required to provide the
Services only to the extent and only at the locations such Services are being
provided by Providing Company for the members of Receiving Company's Group

only for purposes of conducting the business of Receiving Company substantially
in the manner it was conducted prior to the Effective Date.

                  (b)      IMPRACTICABILITY. Providing Company shall not be
required to provide any Service to the extent the performance of such Service
becomes "Impracticable" as a result of a cause or causes outside the reasonable
control of Providing Company including unfeasible technological requirements, or
to the extent the performance of such Services would require Providing Company
to violate any applicable laws, rules or regulations or would result in the
breach of any software license or other applicable contract.

Affiliates), relating to ownership of copyrights, and the Patent and Technology

         Receiving Company shall return to Providing Company, as soon as
         practicable, any equipment or other property of Providing Company
         relating to the Services which is owned or leased by it and is or was

terminate this Agreement either with respect to all, or with respect to any one
or more, of the Data Processing Services, Telecommunications Services or Common
Support Services provided hereunder at any time and from time to time, for any

the date on which Providing Party receives written notice of Receiving Company's
termination.

                  (b)      PROVIDING COMPANY TERMINATION. Except where a longer
term is set forth in an Exhibit for any particular Service, Providing Company

                  (b)      LIMITATION OF LIABILITY; INDEMNIFICATION OF RECEIVING
COMPANY. Providing Company shall have no Liability to Receiving Company with
respect to its furnishing any of the Services hereunder except for Liabilities
arising out of the willful misconduct occurring after the Effective Date of
Providing Company or any member of Providing Company's Group. Providing Company
will indemnify, defend and hold harmless Receiving Company Indemnitees in
respect of all Liabilities related to, arising from, asserted against or
associated with such willful misconduct. Such indemnification obligation shall
be a Liability of Providing Company for purposes of the Contribution and
Distribution Agreement and the provisions of Article V thereof with respect to
indemnification shall govern with respect thereto. In no event shall Providing
Company or any member of Providing Company's Group have any Liability for any
incidental, indirect, special or consequential damages, whether or not caused by
or resulting from negligence or breach of obligations hereunder and whether or
not informed of the possibility of the existence of such damages.

                  (c)      LIMITATION OF LIABILITY; INDEMNIFICATION OF PROVIDING
COMPANY. Receiving Company shall indemnify and hold harmless Providing Company's
Indemnitees in respect of all Liabilities related to, arising from asserted
against or associated with Providing Company' furnishing or failing to furnish
the Services provided for in this Agreement, other than Liabilities arising out
of the willful misconduct following the Effective Date of Providing Company or
any member of Providing Company's Group. The provisions of this indemnity shall
apply only to losses which relate directly to the provision of Services. Such
indemnification obligation shall be a Liability of Receiving Company for
purposes of the Contribution and Distribution Agreement and the provisions of
Article V thereof with respect to indemnification shall govern with respect
thereto. In no event shall Receiving Company or any member of Receiving
Company's Group have any Liability for any incidental, indirect, special or
consequential damages, whether or not caused by or resulting from negligence or
breach of obligations hereunder and whether or not informed of the possibility
of the existence of such damages.

                  (d)      SUBROGATION OF RIGHTS VIS-A-VIS THIRD PARTY
CONTRACTORS. In the event any Liability arises from the performance of Services
hereunder by a third party contractor, Receiving Company shall be subrogated to
such rights, if any, as Providing Company may have against such third party
contractor with respect to the Services provided by such third party contractor
to or on behalf of Receiving Company.

its receipt of Services under this Agreement, including any tax which Receiving
Company is required to withhold or deduct from payments to


                                      -11-
<PAGE>   14
Providing Company, except (a) any tax allowable as a credit against the U.S.
Federal income tax of Providing Company, and (b) any net income tax imposed upon
Providing Company by the country of its incorporation or any governmental entity
within its country of incorporation. To assist Providing Company in obtaining

         3.2      LAW AND GOVERNMENTAL REGULATIONS.

                  Receiving Company shall be responsible for (a) compliance with
all laws and governmental regulations affecting its business and (b) any use
Receiving Company may make of the Services to assist it in complying with such
laws and governmental regulations. While Providing Company shall not have any
responsibility for Receiving Company's compliance with the laws and regulations
referred to above, Providing Company agrees to use reasonable efforts, subject
to Section 2.5(c), to (i) provide the Services in a manner that complies with
applicable laws and regulations and (ii) cause the Services to be designated in
such manner that such Services shall be able to assist Receiving Company in
complying with applicable legal and regulatory responsibilities. Providing
Company's charge, if any, for such Service may reflect its efforts under this
Section 3.2. In no event, however, shall Receiving Company rely solely on its
use of the Services in complying with any laws and governmental regulations.

         3.3      RELATIONSHIP OF PARTIES.

                  Nothing in this Agreement shall be deemed or construed by the

partnership or joint venture between the parties, it being understood and agreed
that no provision contained herein, and no act of the parties, shall be deemed
to create any relationship between the parties other than the relationship of
independent contractor nor be deemed to vest any rights, interest or claims in
any third parties.
