     Service(s) during the Initial Term and for any Renewal Term, as specified
     in paragraph 2.2(b) below.

     ("Supplemental Services") where such services are not included within the

     that Supplemental Services are required on an emergency basis. Exodus may
     provide such services without the consent of Customer, thereafter provide
     notice of the services to Customer and bill Customer a reasonable fee for
     such services. Customer agrees to pay Exodus the fees charged by Exodus for
     Supplemental Services. Customer will be charged for Supplemental Services
     in the invoices issued the month following delivery of the services. Exodus
     will use commercially reasonable efforts to provide

          (b) Renewal Term(s). Each Service will continue automatically for
     additional terms equal to the Initial Term ("Renewal Term") unless Customer
     notifies Exodus in writing at least thirty (30) days prior to the end of
     the Initial Term or a Renewal Term, as applicable, that it has elected to
     terminate such Service, in which case such Service shall terminate at the
     end of such term. The termination of any Service will not affect Customer's
     obligations to pay for other Service(s). Notwithstanding the foregoing,
     Exodus may change or increase the prices it charges Customer for any
     Service at any time after the Initial Term effective thirty (30) days after
     providing notice to Customer. This paragraph 2.2(b) does not apply to

                    Exodus will remedy the Performance Problem within two (2)
                    hours of determining the source of the Performance Problem.
                    If the source of and remedy to the Performance Problem
                    reside outside of the Exodus LAN or WAN, Exodus will use

                    responsible for the source of the Performance Problem and

                    Performance Problem within the time periods described in
                    subsection (i) and/or (B) Exodus is the sole source of the
                    Performance Problem and is unable to remedy such Performance
                    Problem within the time period described in subsection (ii)
                    above, Exodus will deliver a Service Credit to Customer for
                    such two (2) hour period in excess of the time periods for
                    identification and resolution described above.

     the Service Credits described in this Section 5.2, Customer must notify
     Exodus within seven (7) days from the time Customer becomes eligible to
     receive a Service Credit. Failure to comply with the requirement will
     forfeit Customer's right to receive a Service Credit.

ORDER FORM

ORDER FORM TERMS AND CONDITIONS:

(1)  Customer hereby orders and SAVVIS Communications Corporation ("SAVVIS")
     hereby agrees to provide the services, hardware and/or software described
     in this Order Form (also known as a "Service Order") (collectively, "the
     Services").

(2)  THE SERVICES ARE PROVIDED PURSUANT TO THE TERMS AND CONDITIONS OF THIS
     ORDER FORM AND THE TERMS AND CONDITIONS OF THE FOLLOWING SAVVIS DOCUMENTS:

     a) Service Schedule(s), SAVVIS Service Guide, Service Addenda including any
     applicable Specification Sheet(s), SLA(s), and/or Statement(s) of work
     signed by Customer and SAVVIS.

     b) The appropriate services agreement between Customer and SAVVIS whether
     it be a Master Services Agreement or any predecessor agreement under which
     services are still currently being provided. A service order does not
     constitute a predecessor agreement for purposes of this section.

(3)  The Customer representative signing below hereby acknowledges and agrees
     that in the event that Customer does not issue a purchase order prior to
     the requested service date, this Order Form shall serve as Customer's
     purchase order. Customer further acknowledges that any additional or
     conflicting terms and conditions contained in Customer's purchase order
     shall not be applicable to the services to be provided hereunder, even if
     SAVVIS uses such purchase order for invoicing purposes.

(4)  Unless this Order Form is executed by Customer and accepted by SAVVIS (i)
     within thirty (30) days after its creation date (as indicated herein) or
     (ii) after the time period for which this Order Form is valid; this Order
     Form shall automatically expire and be rendered void. Without limiting any
     other SAVVIS right, acceptance of this Order Form is subject to SAVVIS
     credit approval.

(5)  If the Customer and/or its end users delay the Installation Date for the
     Services beyond ninety (90) days of Customer's signature of this Order Form
     and the parties have not agreed in writing to extend the Installation Date,
     then SAVVIS has the right to charge Customer a fee equivalent to one (1)
     month recurring charges as set forth in this Order Form (or  *  percent
     (*%) of the aggregate annualized value of the Order Form in the event a
     material portion of the Services do not contain monthly recurring charges).

(6)  Customer shall have the right to terminate this Service Order at any time,
     with or without casue, upon thirty (30) days prior written notice, provided
     that in the event Customer terminates this Service Order during the first *
     (*) months of the Initial Term (i.e. *), Customer shall be liable for the
     cumulative total of the balance of *% of all monthly charges remaining
     through the end of the Initial Term plus any charges accrued but unpaid as
     of the effective date of termination. In the event Customer terminates this
     Service Order during the remainder of the Initial Term (i.e. effective on
     or after *), Customer shall not be liable for any early termination charge
     except that Customer shall pay for charges accrued but unpaid as of the
     effective date of termination. Notwithstanding anything to the contrary,
     the effective date of this Service Order shall be March 30, 2007.

     The provisions of this Item 6 shall supersede any conflicting items and
     conditions in a prior Order Form and the applicable services agreement.

ORDER FORM

(7)  Customer shall have ten (10) calendar days from the date SAVVIS notifies
     Customer that the applicable services are installed and operational
     ("Installation Date") to confirm acceptance of such services via an
     executed Customer Acceptance Form ("CAF"). In the event Customer does not
     return the CAF to SAVVIS in accordance with this paragraph at SAVVIS' sole
     option, either (i) the CAF will be deemed accepted or (ii) SAVVIS may
     terminate the applicable Services without liability or further obligation,
     and Customer will be charged, and Customer agrees to pay for, any and all
     set-up fees, de-installation fees or charges for Services terminated.

(8)  SAVVIS may increase the rates associated with existing co-location facility
     services at any time after twelve months of the initial Installation Date
     for such Service in order to pass through increases in such Service's
     underlying power facility costs by notifying Customer at least thirty (30)
     days prior to the effective date of such rate change. For Services where
     the price stated on the Service Order includes charges for both space and
     power, forty-five percent (45%) of the aggregate charges will be considered
     power charges for purposes of calculating any such rate increase.

(9)  THERE ARE IMPORTANT TERMS AND CONDITIONS, WARRANTY DISCLAIMERS, LIABILITY
     LIMITATIONS AND SERVICES DESCRIPTIONS CONTAINED IN THE APPLICABLE SERVICES
     AGREEMENTS, SERVICE SCHEDULES, AND SERVICE ADDENDA (INCLUDING SPECIFICATION
     SHEETS AND/OR STATEMENTS OF WORK) ("CONTRACT DOCUMENTS"). DO NOT SIGN THIS
     ORDER FORM UNTIL YOU HAVE READ ALL THE TERMS OF THE CONTRACT DOCUMENTS THAT
     PERTAIN TO THIS ORDER. YOUR SIGNATURE BELOW INDICATES YOU HAVE READ THE
     TERMS OF THIS ORDER FORM AND THE ADDITIONAL TERMS IN THE CONTRACT DOCUMENTS
     AND AGREE TO BE BOUND BY THEM.
