         conditions contained herein, to use the Space in the Premises as
         delineated on Exhibit A attached hereto with respect to which Customer

         be utilized by the Customer only for location of the Customer
         Equipment, related activities and as agreed between the parties
         pursuant to this Agreement.

2.2      In connection with the Space made available hereunder, SAVVIS shall
         perform the Services at no additional charge to Customer, except as
         otherwise specifically provided on Exhibit B. However, Customer shall

         debris from the Space. In addition, Customer shall not cause the
         condition of the Space to become unsafe, as determined by any
         reasonable standards established by SAVVIS or as required by applicable
         law.

2.3      Customer shall have access to the Space at any time on any date;
         provided, however, Customer shall be required to comply with such
         reasonable security requirements as SAVVIS shall from time to time
         notify the Customer in advance with respect to entry on the Premises.
         SAVVIS shall provide Customer with any documents, cards or other items
         necessary to permit Customer unfettered access in compliance with any
         such security requirements.

2.4      Customer acknowledges that it has been granted only a license (subject
         to the terms and conditions contained herein) to occupy the Space and
         that Customer has not been granted any real property interest in the

2.5      Notwithstanding the provisions of Section 2.4 above, Customer shall,
         with SAVVIS' prior written consent, such consent not to be unreasonably
         withheld,


                                       3

         conditioned or delayed, be entitled to grant a sublicense of the Space
         to a third party on substantially the same terms and conditions as this
         Agreement, except that any fees collected by Customer from any
         sublicense of the Space to a third party shall not be materially
         different from the fees collected by SAVVIS from third parties for
         comparable volume and term. Customer acknowledges that SAVVIS may
         reasonably withhold consent to the sublicense by Customer of the Space
         to the direct competitors of SAVVIS listed on Exhibit C attached
         hereto, as such exhibit may be amended from time to time in accordance
         with the Change Control Procedure set forth in Schedule 7.3 to the
         Network Services Agreement. Customer may without limitation provide
         services to its customers, which services include the Space, bundled
         with Customer's own services.

3.       TERM OF AGREEMENT, RENEWAL, RIGHT OF FIRST REFUSAL

3.1      This Agreement shall take effect from the Effective Date and shall
         continue for a period of five (5) years (the "INITIAL TERM").
         Thereafter, this Agreement may be renewed by Reuters, in its sole
         discretion, for additional one year periods (each, a "RENEWAL TERM") by
         giving SAVVIS not less than one hundred and eighty (180) days prior
         written notice, to expire on the next anniversary of the Effective Date
         (together with the Initial Term, the "TERM"). Notwithstanding the
         foregoing, this Agreement shall terminate concurrently with the
         termination of the Network Services Agreement. This Section 3.1 shall
         be subject to the provisions of Section 6 hereof.

3.2      Notwithstanding anything to the contrary set forth in this Agreement
         (including, without limitation, Section 2.4 hereof), any purchaser or
         successor in interest to SAVVIS including, without limitation, SAVVIS
         itself, if any of the options under SAVVIS' lease for the Premises are
         exercised, of the Premises shall take the Premises subject to this
         Agreement and the rights and obligations hereunder.

3.3      Nothing contained in this Agreement shall prohibit Customer from
         seeking any relief or remedy against the condemning authority in the
         event of an eminent domain proceeding or condemnation that affects the
         Space.

3.4      At such times as SAVVIS has commitments for the purchase of 1000 racks
         and 1,500 racks respectively, including Customer's forecasted
         requirement for approximately [**] racks hereunder, SAVVIS shall notify
         Customer and Customer shall thereafter have forty-five (45) days from
         the date of receipt of SAVVIS' notice to purchase as many additional
         racks as Customer desires at SAVVIS' then current rates, as such rates
         are offered to other customers for comparable volume and term, or as
         otherwise may be mutually agreed between the parties, such racks to be
         installed in a commercially reasonable time frame. In the event that
         Customer determines to purchase additional racks pursuant to the terms
         of this Section 3.4, SAVVIS agrees that in accordance with the
         provisions of the last sentence of

         [**] CONFIDENTIAL TREATMENT REQUESTED

                                       4
<PAGE>

         Section 3.5 hereof, it will install such additional racks adjacent to
         the racks Customer currently has at the time Customer purchases such
         additional racks.

3.5      Customer may, at any time during the Term, submit a written request to
         SAVVIS requesting additional space ("ADDITIONAL SPACE") in the
         Premises. SAVVIS shall reasonably consider any such request in good
         faith and shall promptly notify Customer of its decision and in any
         event within thirty (30) days of Customer's request. SAVVIS shall
         consider any such request no less favorably than any request submitted
         by a third party. The parties shall agree in good faith the price for
         any such Additional Space which shall not be more than the price
         calculated on a per square foot basis being paid for the Space at the
         time of the Customer's request. Any Additional Space shall be provided
         in accordance with the provisions of this Agreement and shall be
         adjacent to the Space currently occupied by Customer at the time of
         Customers' request, unless the parties agree to the contrary. SAVVIS
         agrees that in order to provide Customer Additional Space which is
         adjacent to the Space currently occupied by Customer at the time of
         Customer's request, SAVVIS will first use all space that is not
         adjacent to the Space occupied by Customer for any purpose other than
         as required by Customer.

4.       PRICES AND PAYMENT TERMS

4.1      Customer shall pay SAVVIS a monthly fee equal to [**] (the "Monthly
         Fee"), for twenty five percent (25%) of the building space or 27,250
         square feet, which area constitutes the Space as described on Exhibit A
         attached hereto. Billing for the Space shall commence on the Effective
         Date. All payments are due within thirty (30) days after the date of
         receipt by Reuters of such invoice. In no event shall Customer be
         obligated to pay for any real estate taxes, assessments or any other
         government imposition on the Premises or the underlying land. SAVVIS
         may charge Customer an interest rate equal to the lesser of [**] for
         any monthly fee not paid within such thirty-day period. All payments
         required by this Agreement are exclusive of any national, state,
         municipal or other governmental excise, sales, value-added and
         occupational taxes and other levies, all of which Customer shall be
         responsible for, and will pay in full, other than taxes based on
         SAVVIS' net income.

4.2      The Monthly Fee payable hereunder shall remain the same during the
         Initial Term of this Agreement. Prior to the end of the Initial Term
         and at the end of each subsequent Renewal Term, the Monthly Fee payable
         shall be reviewed by SAVVIS and adjusted effective on and from the
         fifth anniversary of the Effective Date ("ADJUSTMENT DATE"), to an
         amount equal to the lesser of (i) the product obtained by multiplying
         the then current Monthly Fee by a fraction, the numerator of which is
         the Consumer Price Index For All Urban Consumers, All Items for the St.
         Louis metropolitan area (1982-1984 = 100), published monthly or
         otherwise in the "Monthly Labor Review" of the Bureau of Labor
         Statistics of the United States Department of Labor ("CPI"), for the
         month preceding the month in which the

         [**] CONFIDENTIAL TREATMENT REQUESTED

                                       5
<PAGE>

         Adjustment Date falls, and the denominator of which is the CPI for the
         calendar month in which the Commencement Date occurs, and (ii) [**]. In
         no event shall the Monthly Fee as adjusted be less than the Monthly Fee
         for the previous twelve month period.

4.3      SAVVIS shall, within one hundred and twenty (120) days prior to the
         Adjustment Date, give Customer written notice of any such adjustment,
         and Customer shall commence paying the Monthly Fee as adjusted from the
         Adjustment Date.

4.4      In the event the CPI is discontinued and not replaced by a successor
         index by the Bureau of Labor Statistics, the adjustments to be made
         hereunder shall be made based upon a nationally recognized and accepted
         comparable statistical index meaning the cost of living for the City of
         St. Louis in order to carry out the intent of Section 4.2 hereof.

4.5      If Customer in good faith disputes the accuracy or legitimacy of any
         SAVVIS charge or invoice, Customer shall promptly notify SAVVIS of such
         dispute and pay any undisputed amount by the due date. The parties
         shall resolve any such dispute in accordance with the provisions of
         Section 14 below. Customer shall not be deemed to be in breach of this
         Agreement for non-payment if it is withholding payment of any amounts
         that are disputed in good faith and Customer has promptly provided a
         written statement to SAVVIS describing the basis of the dispute and the
         amount being withheld. SAVVIS shall not deny, suspend or restrict any
         Service pending the outcome of any billing dispute. Where resolution of
         any such dispute determines that Customer should pay the disputed
         amount, SAVVIS may charge Customer interest on such disputed amount
         from the due date to the dates such sum is actually paid at the then
         current LIBOR rate.

4.6      No more than once in any twelve (12) month period, Customer shall have
         the right (either itself and/or through its third party contractors) to
         conduct an audit to verify that Fees for the Services are being charged
         by SAVVIS in accordance with the terms of this Agreement (an "AUDIT");
         provided that the compensation of any third party contractor performing
         an Audit shall not be contingent upon the results of such Audit. SAVVIS
         shall provide to Customer and its third party contractor reasonable
         facilities and access to the Premises during normal office hours, and
         such documents and information as Customer shall reasonably require for
         the purposes of the Audit, but in no event shall SAVVIS be required to
         provide Customer or its third party contractor with any Confidential
         Information of SAVVIS that is not necessary to properly conduct such
         Audit. Customer shall ensure that any third party contractor hired by
         Customer to perform an Audit shall execute a confidentiality agreement
         which protects the Confidential Information of each party to no lesser
         extent than as set out in Section 13 prior to the start of any Audit.
         If any Audit shows that Customer was actually charged Fees for the
         Services by SAVVIS that were more than [**] above what should have been

         [**] CONFIDENTIAL TREATMENT REQUESTED

                                       6
<PAGE>

         charged Customer by SAVVIS in accordance with the terms of this
         Agreement, then SAVVIS shall reimburse Customer for any reasonable fees
         paid by Customer for such Audit.

4.7      The Space is being provided to Customer in accordance with the
         description set out in Exhibit B. Customer, at its own cost and
         expense, shall have the right to install racks and such other equipment
         as is necessary to install the Customer Equipment, with the prior
         written consent of SAVVIS, which consent shall not be unreasonably
         withheld, conditioned or delayed. Customer shall be responsible for
         connecting electrical power to the Customer Equipment, which electrical
         power shall be separately metered. The parties shall mutually agree on
         the method to be used for measuring and metering the power.

4.8      Customer shall connect the Customer Equipment at the Premises to its
         carrier services by ordering such services through SAVVIS and the rates
         Customer shall pay to SAVVIS for such services shall in no event be
         greater than the actual amount of the rates charged to SAVVIS by its
         carriers, plus the cost of the administrative fees, as set forth on
         Exhibit B.

4.9      Customer agrees to reimburse SAVVIS for all reasonable repair or
         restoration costs associated with damage or destruction caused by
         Customer's personnel, its agents or its suppliers/contractors or
         Customer's visitors during the Term or as a consequence of its removal
         of the Customer Equipment or property installed in the Space. Customer
         shall not make any construction changes or material alterations to the
         interior or exterior portions of the Space, without obtaining SAVVIS'
         written approval for Customer to have the work performed or have SAVVIS
         perform the work, such approval not to be unreasonably withheld,
         conditioned or delayed. SAVVIS shall have the right to bid for
         construction or material alterations within the Premises and Space
         areas at rates to be negotiated between the parties hereto.

4.10     Customer's use of the Space, installation of Customer Equipment and
         access to the Premises shall at all times be subject to Customer's
         adherence to the reasonable security rules and rules of conduct
         notified by SAVVIS in advance to Customer in writing for the Premises.
         SAVVIS shall provide Customer with any documents, cards or other items
         necessary to permit Customer to have unfettered access in compliance
         with any such security requirements. Customer agrees not to erect any
         signs or devices to the exterior portion of the Space without
         submitting the request to SAVVIS and obtaining SAVVIS' written
         approval, such approval not to be unreasonably withheld, conditioned or
         delayed.

5.       INSURANCE

5.1      Customer agrees to maintain, at its expense, during the Term (i)

         SAVVIS' reasonable written request, furnish SAVVIS with certificates of
         insurance and evidence of property which evidence the minimum levels of
         insurance set forth herein.

6.       TERMINATION

                  Agreement (including Services provided hereunder, which shall
                  be provided in accordance with Exhibit B attached hereto), and
                  SAVVIS has failed to cure such failure or violation within

6.2      Customer shall have the right to terminate this Agreement, with no
         liability to SAVVIS other than for charges (less any applicable
         credits) for the Services provided prior to such termination, if (i)
         Customer provides ten (10) days prior written notice of its intent to

         Network Services Agreement otherwise terminates in accordance with its
         terms.

                  Customer with written notice thereof; provided, that Customer

         taking by eminent domain by any authority having such power or a
         transfer in lieu thereof (a "Condemnation"), then Customer may
         terminate this Agreement. If the Condemnation is temporary and Customer
         does not terminate this Agreement, then Monthly Fees shall be abated.
         If a condemnation does not affect the entire Premises and Customer does
         not terminate this Agreement, then SAVVIS shall be obligated to restore
         the remainder of the Premises and Monthly Fees shall be reduced to
         reflect the loss of square footage.

6.5      Upon termination or expiration of the Term, Customer agrees to remove
         within ninety (90) days the Customer Equipment and other property that
         has been installed by Customer or its agents. If this Agreement is
         terminated pursuant to Sections 6.1, 6.3 or 6.4 hereof prior to the end
         of a monthly period covered by the Monthly Fee, SAVVIS shall promptly
         refund to Customer a pro-rata portion of such Monthly Fee.

         all claims that the Space used by Customer hereunder infringes on any

         proprietary rights. SAVVIS shall, at SAVVIS' sole option, either (i)
         settle any such claim, (ii) secure valid rights for Customer's

         Customer provides SAVVIS with all pertinent information in Customer's
         possession relative to such claim and (iii) SAVVIS shall have sole

                  for the Space. The Customer Equipment shall not be deemed or
                  become a fixture in the Premises;

         (b)      the Services will be performed in a competent manner by

         WARRANTIES SET FORTH IN THIS ARTICLE, THERE ARE NO WARRANTIES, WHETHER

         claim, action or proceeding by a third party alleging that the Services
         or the use thereof as permitted in this Agreement directly caused any
         bodily injury or damage to tangible property by a third party and
         SAVVIS agrees to pay all damages costs, liabilities or expenses
         incurred by the Customer resulting from such claim, action or
         proceeding (or settlements thereof), including reasonable attorney's

         such claim; and (ii) reasonable assistance to defend or settle such
         claim at the Indemnitor's expense. The Indemnitee agrees that the

13.      CONFIDENTIALITY

13.1     During the Term and for a period of five (5) years from the date of its
         expiration or termination (including all extensions thereof), each
         party agrees to maintain in strict confidence all Confidential
         Information received by it from the other party. Neither party shall,
         without prior written consent of the other party, use the other party's
         Confidential Information for any purpose other than for the performance
         of its duties and obligations, and the exercise of its rights, under
         this Agreement. Each party shall use, and shall cause all authorized
         recipients of the other party's Confidential Information to use, the
         same degree of care to protect the other party's Confidential
         Information as it uses to protect its own Confidential Information, but
         in any event not less than a reasonable degree of care.

13.2     Notwithstanding Section 13.1 hereof, either party may disclose the
         Confidential Information of the other party to: (a) in the case of
         Customer, its employees and the employees, directors and officers of
         the Customer Group solely as necessary to implement this Agreement; or
         (b) in the case of SAVVIS, its employees and the employees, directors
         and officers of the SAVVIS Group solely as necessary to implement this
         Agreement and (c) other persons (including counsel, consultants,
         lessors or managers of facilities or equipment used by such party) in
         need of access to such information for purposes specifically related to
         either party's responsibilities under this Agreement, provided that any
         disclosure of Confidential Information under clause (c) of this Section
         13.2 shall be made only subject to the appropriate assurances that the
         recipient of such information shall hold in strict confidence.

13.3     Upon the request of the party having proprietary rights to Confidential
         Information, the party in possession of such information shall promptly
         return it (including any copies, extracts, and summaries thereof, in
         whatever form and medium recorded) to the requesting party or, with the
         other party's prior written consent, shall promptly destroy it and
         provide the other party with written certification of such destruction.

13.4     Either party may request in writing that the other party waive all or
         any portion of the requesting party's responsibilities relative to the
         other party's Confidential Information. Such waiver request shall
         identify the affected information and the nature of the proposed
         waiver. The recipient of the request shall respond within a reasonable
         time and, if it determines, in its sole discretion, to grant the
         requested waiver, it will do so in writing over the signature of an
         employee authorized to grant such request. Any failure by a party not
         to respond to such request will not be deemed approval of such request.

13.5     Reuters and SAVVIS acknowledge that any disclosure or misappropriation
         of Confidential Information in violation of this Agreement could cause
         irreparable harm, the amount of which may be difficult to determine,
         thus potentially making


                                       13
<PAGE>

         any remedy at law or in damages inadequate. Each party, therefore,
         agrees that the other party shall have the right to apply to any court
         of competent jurisdiction for an order restraining any breach or
         threatened breach of this Section and for any other appropriate relief.
         This right shall be in addition to, and not in lieu of, any other
         remedy available in law or equity.

13.6     Notwithstanding the foregoing, this Section will not apply to any
         information which a party can demonstrate was:

         (a)      at the time of disclosure to it, in the public domain;

         (b)      after disclosure to it, published or otherwise became part of
                  the public domain through no fault of the party;

         (c)      in the possession of the receiving Party at the time of
                  disclosure to it;

         (d)      received after disclosure to it from a third party who had a
                  lawful right to disclose such information to it; or

         (e)      independently developed by it without reference to
                  Confidential Information of the other party.

13.7     A party requested or ordered by a court or other governmental authority
         of competent jurisdiction to disclose another party's Confidential
         Information shall notify the other party in advance of any such
         disclosure to afford the other party the opportunity to seek any
         protections against such disclosure as may be available. Absent the
         other party's consent to such disclosure, such party will use its best
         efforts to resist, and to assist the other party in resisting, such
         disclosure, including without limitation using its best efforts to
         obtain a protective order or comparable assurance that the Confidential
         Information so provided will be held in confidence and not further
         disclosed to any other person, absent the owner's prior consent. Any
         Confidential Information that may be required to be disclosed shall
         remain Confidential Information as between the parties hereto.

13.8     Notwithstanding any provisions of this Agreement to the contrary,
         either party may disclose the terms and conditions of this Agreement in
         the course of a due diligence review performed in connection with
         prospective debt financing or equity investment by, or a sale to, a
         third party, so long as the persons conducting such due diligence
         review have agreed to maintain the confidentiality of such disclosure
         and not to use such disclosure for any purpose other such due diligence
         review.

14.      DISPUTE RESOLUTION

14.1     In the event that any dispute between SAVVIS and Reuters arises from or
concerns in any manner the subject matter of this Agreement, each party will

<PAGE>


to resolve such dispute through discussion between its employees in the
following order: first, within five (5) days following receipt of any written
request by a member of the Reuters Group or SAVVIS, as the case may be, of a

the Relationship Managers are unable to resolve such dispute within ten (10)

Reuters Global Operations and the comparative executive of SAVVIS shall meet in
person to resolve such dispute; and finally in the event the respective managers
of Reuters Global Operations and the comparative-level executive at SAVVIS are
unable to resolve such dispute within twenty-five (25) days following receipt of
a Dispute Notice, then the Chief Operating Officer of the Reuters Group and the
Chief Operating Officer of SAVVIS shall meet in person or by other agreed means
to resolve such dispute. If the respective Chief Operating Officers cannot

unresolved dispute as provided under this Agreement. Any meetings between the
employees set forth above may occur in New York, New York, if such meeting is to
