         policies, judgments and rights thereunder, and tort claims; and

                  (r)  all Proceeds and products of any or all of the foregoing;

                         Representations and Warranties
                         ------------------------------

         To induce Secured Party to enter into this Agreement, Debtor represents
and warrants to Secured Party that:

         Section 3.1    Title. Debtor has rights in and the power to
transfer and grant a security interest in each item of the Collateral upon which
it purports to grant a Lien hereunder free and clear of any Lien or other
encumbrance, except for those Permitted Encumbrances (if any) which are
expressly permitted to attach to the Collateral in accordance with the Restated
Lease Agreement and Liens in favor of Secured Party, and provided, that this
Section 3.1 does not apply to Intellectual Property (which is addressed in
Section 3.8 below).

         Section 3.2    Accounts. Unless Debtor has given Secured Party
written notice to the contrary, whenever the security interest granted hereunder
attaches to an Account with a value in excess of $250,000, Debtor shall be
deemed to have represented and warranted to Secured Party as to each of such
Accounts at the time of its creation that (a) each such Account is genuine and
in all respects what it purports to be, (b) each such Account represents the
legal, valid and binding obligation of the account debtor evidencing
indebtedness unpaid and owed by such account debtor, (c) to the best knowledge
of Debtor, except for defenses and business disputes arising in the ordinary
course of business which in the aggregate are not material, the amount of each
Account represented as owing is the correct amount actually and unconditionally
owing except for normal trade discounts

SECURITY AGREEMENT (Savvis Communications International, Inc.) - Page 15
<PAGE>

granted in the ordinary course of business, (d) Debtor has not received any
notice of proceedings or actions which are threatened or pending against any
account debtor which might result in any adverse change in such account debtor's
financial condition, and (e) no Account is subject to any offset, counterclaim
or other defense (nor is it subject to any threatened counterclaim to the best
knowledge of Debtor) and, except to the extent otherwise provided in the
Restated Lease Agreement, Debtor has not made any agreement with any account
debtor for any extension of time for the payment thereof, any compromise or
settlement for less than the full amount thereof, any release of any account
debtor from liability therefor, or any deduction therefrom, except a discount or
allowance allowed by Debtor in the ordinary course of business for prompt
payment and disclosed to Secured Party.

         Section 3.3    Financing Statements. No financing statement,
security agreement or other Lien instrument covering all or any part of the
Collateral is on file in any public office, except as may have been filed in
favor of Secured Party pursuant to this Agreement and except for financing
statements evidencing Permitted Encumbrances. Except as otherwise disclosed on
Schedule 5, Debtor does not do business and has not done business within the
past five years under a trade name or any name other than its legal name set
forth at the beginning of this Agreement.

         Section 3.4    Principal Place of Business; Organization; Tax I.D.
The principal place of business and "chief executive office", as such term is
defined in Article or Chapter 9 of the UCC, of Debtor, and the office where
Debtor keeps its books and records, is located at the address of Debtor
designated in the introductory paragraph of this Agreement. In addition, each of
the "jurisdiction of organization," as such term is defined in Article or
Chapter 9 of the UCC, the name of Debtor as it appears in official filings in
its jurisdiction of organization, the United States Federal income tax
identification number of Debtor and the organizational identification number or
similar identification number assigned to Debtor by the jurisdiction of
organization of Debtor (if any) is as specified in the introductory paragraph of
this Agreement.

         Section 3.5    Location of Collateral. All Fixtures, Inventory
(except Inventory in transit) and Equipment (other than vehicles) of Debtor
constituting Collateral having a value in excess of $100,000 are located at the
places specified on Schedule 4, provided that pursuant to the terms of Section
6.26 of the Restated Lease Agreement, Debtor shall have 90 days after the
Execution Date of the Restated Lease Agreement to provide Secured Party with
such Schedule 4. Debtor shall give written notice to Secured Party at least 30
days prior to the date any such Inventory and/or Equipment is located at any
location other than as set forth on Schedule 4. Except for warehousing and
co-location arrangements, Debtor has exclusive possession and control of its
Inventory and Equipment. Debtor has good, indefeasible and merchantable title to
the Inventory and such Inventory is not subject to any Lien or security interest
or document whatsoever except for the Lien granted to Secured Party, and except
for Permitted Encumbrances. The Inventory is not subject to any licensing,
patent, royalty, trademark, trade name or copyright agreements with any third
parties which would require any consent of any third party upon sale or
disposition of that Inventory or the payment of any monies to any third party
upon such sale or other disposition. The completion of manufacture, sale or
other disposition of such Inventory by Secured Party following an Event of
Default shall not require the consent of any Person and shall not constitute a
breach or default under any contract or agreement to which Debtor is a party or
to which such property is subject. None of

such Inventory (other than Inventory as to which all Documents evidencing such
Inventory have been delivered to Secured Party) or Equipment (other than
vehicles) of Debtor constituting Collateral is evidenced by a Document
(including, without limitation, a negotiable document of title).

manners prescribed in Section 8-106 of the UCC) and all other Instruments,

of Secured Party created herein will constitute a valid and perfected Lien upon
and security interest in the Collateral (except for (a) vehicles covered by
certificates of title, and (b) other Property excluded from the application of
Article or Chapter 9 of the UCC by Section 9-109(c) and (d) of the UCC,
including, without limitation, fixtures and deposit accounts, and (c)
unregistered Intellectual Property in which a security interest cannot be
perfected by said method of filing with the United States Patent and Trademark
Office and the United States Copyright Office (it being understood that due to
uncertainty in the law a filing may also be required with the United States
Patent and Trademark Office and the United States Copyright Office, which filing
cannot be effected prior to registration of such Intellectual Property)),
subject to no equal or prior Liens except for those Liens (if any) which
constitute Permitted Encumbrances and which are, in accordance with the Restated
Lease Agreement permitted to have priority equal to or greater than the Liens
created pursuant to this Agreement. The Perfection Certificate has been
prepared, completed and executed, and the information set forth therein is
correct and complete.

         Intellectual Property set forth on Schedule 1 (consisting of Federally
         registered Trademarks, registered Copyrights and issued Patents) free
         and clear of any Liens, including, without limitation, any pledges,
         assignments, licenses, user agreements and covenants by Debtor not to
         sue third Persons, other than Permitted Encumbrances.

SECURITY AGREEMENT (Savvis Communications International, Inc.) - Page 17
<PAGE>


                  (c)        To Debtor's best knowledge, no claim has been made
         alleging that the use of any of the Intellectual Property set forth on
         Schedule 1 violates or may violate the rights of any third Person.

                  (d)        Each of the Patents and Trademarks identified on
         Schedule 1 as being registered has been properly registered with the
         United States Patent and Trademark Office and each of the Copyrights
         identified on Schedule 1 as being registered has been properly
         registered with the United States Copyright Office.

                  (e)        This Security Agreement is effective to create a
         valid and continuing Lien on and, upon filing of Financing Statements

         and recordation of the Patent Security Agreement and the Trademark
         Security Agreement with the United States Patent and Trademark Office,
         perfected Liens in favor of Secured Party on Debtor's Patents,
         Trademarks and Copyrights (it being understood that due to uncertainty
         in the law a filing may also be required with the United States
         Copyright Office, which filing may not be effective prior to
         registration of such Copyrights) and such perfected Liens are
         enforceable as such as against any and all creditors of and purchasers
         from Debtor.

         Section 3.9         Pledged Shares and Instruments.

                  (a)        The Pledged Shares have been duly authorized and
         validly issued and are fully paid and nonassessable under the laws of
         the jurisdiction of incorporation or organization of the issuers

         duly authorized and validly issued by the obligor(s) thereunder and
         constitute legally enforceable  indebtedness of the obligor(s)
         thereunder.

                  (b)        Debtor is the legal and beneficial owner of the
         Pledged Shares and the Instruments, free and clear of any Lien (other
         than Permitted Encumbrances which are, in accordance with the Restated
         Lease Agreement, permitted to attach to the Pledged Shares), and Debtor
         has not sold, granted any option with respect to, assigned, transferred
         or otherwise disposed of any of its rights or interest in or to the
         Pledged Shares or the Instruments.

                  (c)        On the date hereof, the Pledged Shares constitute
         the percentage of the issued and outstanding Capital Stock of the
         issuers thereof indicated on Schedule 3, as such Schedule 3 may from
         time to time be supplemented, amended or modified.

         Section 3.10        Control Property. The information on Schedule 4 is
true, correct and complete. All Deposit Accounts, Electronic Chattel Paper,
Commercial Tort Claims and Investment Property, respectively, existing on the

                                    ARTICLE 4

                                    Covenants
                                    ---------

         Debtor covenants and agrees with Secured Party that until the
Obligations are paid and performed in full, the rights and obligations of
Secured Party and the Lessors under the Restated Lease Agreement and all
commitments of Secured Party to extend credit have expired or have been
terminated:

         Section 4.1         Encumbrances. Except as otherwise permitted by the
terms of the Restated Lease Agreement relating to the disposition of assets,
Debtor shall not create, permit or suffer to exist, and shall defend the
Collateral against, any Lien or other encumbrance on the Collateral except for
Permitted Encumbrances which are, in accordance with the Restated Lease
Agreement, permitted to attach to such Collateral, and shall defend Debtor's
rights in the Collateral and Secured Party's pledge and collateral assignment of
and security interest in the Collateral against the claims and demands of all
Persons. Subject to the creation or existence of Permitted Encumbrances under
the Restated Lease Agreement, Debtor shall do nothing to impair the rights of
Secured Party in the Collateral.

         Section 4.2         [INTENTIONALLY OMITTED]

         Section 4.3         Disposition of Collateral. Except as expressly
permitted by the terms of the Restated Lease Agreement, Debtor shall not sell,
lease, assign (by operation of law or otherwise) or otherwise dispose of, or
grant any option with respect to, the Collateral or any part thereof without the
prior written consent of Secured Party.

         Section 4.4         Further Assurances.

                  (a)        Generally; Control. At any time and from time to
         time, upon the request of Secured Party, and at the sole expense of
         Debtor, Debtor shall promptly execute and deliver all such further
         agreements, documents and instruments and take such further action as
         Secured Party may reasonably deem necessary or appropriate to preserve
         and perfect its security interest in and pledge and collateral
         assignment of the Collateral and the required priority of such security
         interest, to carry out the terms and provisions and purposes of this
         Agreement and to enable Secured Party to exercise and enforce its
         rights and remedies hereunder with respect to any of the Collateral,
         whether in anticipation of or following the effectiveness of Revised
         Article 9 in any jurisdiction, and, without limiting the generality of
         the foregoing, to the extent any of the Collateral at any time
         constitutes Investment Property, Deposit Accounts, Electronic Chattel
         Paper or Letter of Credit Rights, then Debtor shall

SECURITY AGREEMENT (Savvis Communications International, Inc.) - Page 19
<PAGE>

         cause Secured Party to obtain control of such Collateral in accordance
         with Section 9-314 of the UCC and the corresponding provisions in
         Sections 9-104, 9-105, 9-106 and 9-107 (as applicable) of the UCC,
         pursuant to agreements establishing such control in form and substance
         reasonably satisfactory to Secured Party.

                  (b)        Preservation; Assignments; Intellectual
         Property. Except as otherwise expressly permitted by the terms of the
         Restated Lease Agreement relating to disposition of assets and except
         for Permitted Encumbrances, Debtor agrees to defend the title to the
         Collateral and the Lien thereon of Secured Party against the claim of
         any other Person and to maintain and preserve such Lien. Without
         limiting the generality of the foregoing, Debtor shall (a) execute and
         deliver to Secured Party such financing statements, including
         transmitting utility filings, continuation statements and amendments
         thereto (collectively, "Financing Statements"), as Secured Party may
         from time to time require; (b) deliver and pledge to Secured Party all
         Documents (including, without limitation, all documents of title)
         evidencing Inventory or Equipment having a value in excess of $100,000
         (except for certificates of title covering vehicles unless otherwise
         required by Secured Party) and cause Secured Party to be named as
         lienholder on all such Documents; (c) deliver and pledge to Secured
         Party all Instruments and Chattel Paper of Debtor having a value in
         excess of $100,000 with any necessary endorsements; (d) if and to the
         extent required by the Restated Lease Agreement, execute and deliver to
         Secured Party an assignment (in form and substance satisfactory to
         Secured Party) of contract rights under any material Contract following
         (and in any event, within ten days after) the execution thereof and
         obtain from each of the parties to each of the material Contracts,
         other than Subsidiaries and affiliates of Savvis who grant security
         interests in such contracts to Secured Party, an agreement in writing,
         in form and substance satisfactory to Secured Party, pursuant to which,
         among other things, such parties consent to the grant of such security
         interests; (e) execute and deliver to Secured Party, at the request of
         Secured Party, all such agreements, documents, instruments and other
         items as may be reasonably necessary or appropriate for Secured Party
         to create and perfect its security interest in the Intellectual
         Property and to make all appropriate filings with respect thereto; and
         (f) execute and deliver to Secured Party such other agreements,
         documents and instruments as Secured Party may reasonably require to
         perfect and maintain the validity, effectiveness and priority of the
         Liens intended to be created by the Restated Lease Agreement.

                  (c)        Financing Statements. Debtor authorizes Secured
         Party to file one or more Financing Statements or continuation
         statements relating to all or any part of the Collateral without the
         signature of Debtor where permitted by law. A carbon, photographic or
         other reproduction of this Agreement or of any Financing Statement
         covering the Collateral or any part thereof shall be sufficient as a
         Financing Statement and may be filed as a Financing Statement. Secured
         Party may, at any time and from time to time, pursuant to the
         provisions of this Section 4.4, file Financing Statements that describe
         the Collateral as all assets and/or all personal Property of Debtor or
         words of similar effect and which contain any other information
         required by Part 5 of Revised Article 9 for the sufficiency or filing
         office acceptance of any Financing Statement, including whether Debtor
         is an organization, the type

SECURITY AGREEMENT (Savvis Communications International, Inc.) - Page 20
<PAGE>

         of organization and any organization identification number issued to
         Debtor. Debtor agrees to furnish any such information to Secured Party
         promptly upon request. Any such Financing Statements may be signed by
         Secured Party on behalf of Debtor and may be filed at any time in any
         jurisdiction whether or not Revised Article 9 is then in effect in
         that jurisdiction. Debtor acknowledges that it is not authorized to
         file any Financing Statement or amendment or termination statement
         with respect to any Financing Statement without the prior written
         consent of Secured Party and agrees that it will not do so without the
         prior written consent of Secured Party, subject to Debtor's rights
         under Section 9-509(d)(2) of the UCC.

         Section 4.5         Insurance. Debtor shall maintain insurance in the
types and amounts, and under the terms and conditions, specified in Section
5.4(a) of the Restated Lease Agreement. If applicable, recoveries under any such
policy of insurance shall be paid as provided in Section 5.4(c) of the Restated
Lease Agreement.

         Section 4.6         Bailees. If any of the Collateral is at any time in
the possession or control of any warehouseman, bailee or any of Debtor's agents
or processors, Debtor shall, at the request of Secured Party, notify such
warehouseman, bailee, agent or processor of the security interest created
hereunder, shall instruct such Person to hold such Collateral for Secured
Party's account subject to Secured Party's instructions and shall cause such
Person to acknowledge in writing, in form and substance reasonably satisfactory
to Secured Party, that it holds such Collateral for the benefit of Secured
Party.

         Section 4.7         Inspection Rights. Debtor shall permit Secured
Party and its representatives and agents, during normal business hours and upon
reasonable notice to Debtor, to examine, copy and make extracts from its books
and records, to visit and inspect its Properties and to discuss its business,
operations and financial condition with its officers and independent certified
public accountants. Debtor will authorize its accountants in writing (with a
copy to Secured Party) to comply with this Section. Secured Party and/or its
representatives may, at any time and from time to time at Debtor's expense,
conduct field exams for such purposes as Secured Party may reasonably request
during normal business hours and upon reasonable notice to Debtor.

         Section 4.8         [INTENTIONALLY OMITTED]

         Section 4.9         Corporate Changes. Debtor shall not change its
name, identity, jurisdiction of organization or corporate structure in any
manner that might make any Financing Statement filed in connection with this
Agreement misleading or its United States Federal Tax I.D. Number, in each case
unless Debtor shall have given Secured Party 30 days prior written notice
thereof and shall have taken all action deemed necessary or appropriate by
Secured Party to protect its Liens and the perfection and priority thereof.
Debtor shall not change its principal place of business, chief executive office
or the place where it keeps its books and records unless it shall have given
Secured Party 30 days prior written notice thereof and shall have taken all
action deemed necessary or appropriate by Secured Party to cause its security
interest in the Collateral to be perfected with the priority required by the
Credit Documents.

         Section 4.10        Books and Records; Information. Debtor shall
maintain appropriate books of records and accounts in accordance with GAAP where
required by the Restated Lease Agreement consistently applied in which true,
full and correct entries will be made of its dealings and business affairs.
Debtor shall from time to time at the request of Secured Party deliver to
Secured Party such information regarding the Collateral and Debtor as Secured
Party may reasonably request, including, without limitation, lists and
descriptions of the Collateral and evidence of the identity and existence of the
Collateral. To the extent required by Section 4.4, Debtor shall mark its books
and records to reflect the security interest of Secured Party under this
Agreement.

         Section 4.11        Equipment, Fixtures and Inventory.

                  (a)        Debtor shall keep its Equipment (other than
         vehicles), Fixtures and Inventory (other than Inventory in transit)
         constituting Collateral and having a value in excess of $100,000 at the
         locations specified on Schedule 4 or at such other places within the
         U.S. where all action required to perfect Secured Party's security
         interest in any such Equipment, Fixtures and Inventory with the
         priority required by the Restated Lease Agreement shall have been
         taken; provided that if any such Equipment (other than vehicles),
         Fixtures or Inventory (other than Inventory in transit) is being
         relocated to any jurisdiction where the security interest of Secured
         Party under this Agreement has not been previously perfected, then in
         such case Debtor shall deliver prompt (and in any event within not less
         than 30 days) notice thereof to Secured Party.

                  (b)        Debtor shall maintain material Equipment,
         Fixtures and Inventory  constituting Collateral in good condition
         and repair (ordinary wear and tear excepted) and in accordance with the
         terms of the Restated Lease Agreement. Debtor shall not permit any
         waste or destruction of such Equipment, Fixtures or Inventory or any
         part thereof. Debtor shall not permit such Equipment, Fixtures or
         Inventory to be used in violation of any law, rule or regulation or the
         terms of any policy of insurance. Debtor shall not use or permit any of
         such Equipment, Fixtures or Inventory to be used in any manner or for
         any purpose that would impair its value or expose it to unusual risk.

                  (c)        Within 45 days of the end of each of Debtor's
         fiscal quarters, Debtor shall provide Secured Party with a report
         setting forth in reasonable detail any change during such preceding
         fiscal quarter of the location of any Equipment, Fixtures or Inventory
         (unless such location is one of the locations already specified on
         Schedule 4) constituting Collateral.

         Section 4.12        Warehouse Receipts Non-Negotiable. Debtor agrees
that if any warehouse receipt or receipt in the nature of a warehouse receipt is
issued in respect of any of the Collateral, such warehouse receipt or receipt in
the nature thereof shall not be "negotiable" (as such term is used in Section
7.104 of the UCC) unless such warehouse receipt or receipt in the nature thereof
is delivered to Secured Party; provided, however, that Debtor shall not be
required to deliver any warehouse receipt pursuant to this Section 4.12 unless
the fair market value of such warehouse receipt exceeds $100,000; provided,
further, however, the aggregate fair market value of all

warehouse receipts which have not been delivered to Secured Party pursuant to
this Section 4.12 shall not at any time exceed $250,000.

         Section 4.13        Notification. Debtor shall promptly notify Secured
Party of (a) any Lien, encumbrance or claim (other than Permitted Encumbrances)
that has attached to or been made or asserted against any of the Collateral, (b)
any material change in any of the Collateral, including, without limitation, any
material damage to or loss of Collateral, and (c) the occurrence of any other
event or condition (including, without limitation, matters as to Lien priority)
that could reasonably be expected to have a material adverse effect on the

         Section 4.14        [INTENTIONALLY OMITTED]

         Section 4.15        Intellectual Property.  Except with the written
         consent of Secured Party:

                  (a)        If Debtor shall obtain rights to or become entitled
         to the benefit of any Intellectual Property not identified on Schedule
         1, the provisions of this Agreement shall automatically apply thereto.
         Debtor shall undertake to modify or update Schedule 1 to include any
         such new Intellectual Property and hereby authorizes Secured Party to
         modify or update Schedule 1 to include any such new Intellectual
         Property in the event Debtor fails to timely modify or update Schedule
         1 upon written notice from Secured Party;

                  (b)        Upon the occurrence of any event that would require
         any addition to or modification of Schedule 1 or upon the request of
         Secured Party, Debtor shall furnish to Secured Party statements and
         schedules further identifying the Intellectual Property and such other
         items in connection with the Intellectual Property as Secured Party may
         request. Promptly upon the request of Secured Party, Debtor shall
         modify this Agreement by amending Schedule 1 to include any
         Intellectual Property that becomes part of the Collateral;

                  (c)        If an Event of Default shall have occurred and be
         continuing, Debtor shall use its best efforts to obtain any consents,
         waivers or agreements necessary to enable Secured Party to exercise its
         rights and remedies with respect to the Intellectual Property; and

                  (d)        Debtor shall, at the request of Secured Party,
         execute and deliver to Secured Party a Copyright Security Agreement, a
         Patent Security Agreement, a Trademark Security Agreement and all other
         agreements, documents, instruments and other items as may be necessary
         for Secured Party to file such agreements with the United States
         Copyright Office, the United States Patent and Trademark Office and any
         similar domestic or foreign office, department or agency. Debtor will,
         at any time and from time to time upon the request of Secured Party,
         execute and deliver to Secured Party all such other agreements,
         documents, instruments and other items as may be necessary or
         appropriate for Secured Party to create and perfect its security
         interest in the Intellectual Property and to make all appropriate
         filings with respect thereto.

                  (a)      So long as no Event of Default shall have occurred
                  and be continuing:

                           (i)      Debtor shall be entitled to exercise any
                  and all voting and other consensual rights (including, without
                  limitation, the right to give consents, waivers and
                  notifications in respect of any of the Pledged Collateral)
                  pertaining to any of the Pledged Collateral or any part
                  thereof; and

                           (ii)     Unless an Event of Default shall have
                  occurred and be continuing, Debtor shall be entitled to
                  receive and retain any and all dividends and interest paid in
                  respect of any of the Collateral to the extent permitted by
                  the Restated Lease Agreement; provided, however, that any and
                  all

                                    (A)     Restricted Payments  paid or payable
                           in  violation of the terms of the Restated Lease
                           Agreement,

                                    (B)      Restricted Payments paid or
                           payable other than in cash in respect of, and
                           instruments and other Property received, receivable
                           or otherwise distributed in respect of, or in
                           exchange for, any Collateral,

                                    (C)       Restricted Payments hereafter paid
                           or payable in cash in respect of any Collateral in
                           connection with a partial or total liquidation or
                           dissolution or in connection with a reduction of
                           capital, capital surplus or paid-in-surplus, and

                                    (D)     cash paid,  payable or otherwise
                           distributed  in redemption  of, or in exchange for,
                           any Collateral,

         shall be, and shall be forthwith delivered to Secured Party to hold as,
         Collateral and shall, if received by Debtor, be received in trust for
         the benefit of Secured Party, be segregated from the other Property or
         funds of Debtor and be forthwith delivered to Secured Party as
         Collateral in the same form as so received (with any necessary
         endorsement). All amounts (other than amounts described in clauses
         (ii)(A) through (D) above) received by Secured Party in respect of any
         Pledged Collateral shall be either (1) promptly released to Debtor, so
         long as no Default or Event of Default shall have occurred and be
         continuing or (2) if any Default or Event of Default shall have
         occurred and be continuing, held by Secured Party and (if an Event of
         Default shall have occurred and be continuing) applied as provided by
         the Credit Agreement. During the continuance of any Default, any
         dividends, interest or other distributions (whether in cash,
         securities, Property or otherwise) received by Debtor with respect to
         any Collateral shall be held by Debtor in trust for the benefit of
         Secured Party and during the continuance of any Event of Default, upon
         the request of Secured Party, shall be delivered promptly to Secured
         Party to hold as Collateral or shall be applied by Secured Party toward
         payment of the Obligations, as Secured Party may in its discretion
         determine. If such

SECURITY AGREEMENT (Savvis Communications International, Inc.) - Page 24
<PAGE>


         Event of Default is waived or cured to the satisfaction of Secured
         Party, any such distributions received by Secured Party (except those
         of the types described in clauses (ii)(A) through (D) above which
         shall not be released to Debtor) shall be returned promptly to Debtor
         (provided that no other Default or Event of Default exists).

                  (b)      Upon the occurrence and during the continuance of an
                  Event of Default:

                           (i)        Secured Party may, without notice to
                  Debtor, transfer or register in the name of Secured Party or
                  any of its nominees any or all of the Collateral described in
                  Section 2.1(k) or Section 2.1(o), the proceeds thereof (in
                  cash or otherwise) and all liens, security, rights, remedies
                  and claims of Debtor with respect thereto (collectively, the
                  "Pledged Collateral") held by Secured Party hereunder, and
                  Secured Party or its nominee may thereafter, after delivery of
                  notice to Debtor, exercise all voting and corporate rights at
                  any meeting of any corporation, partnership or other business
                  entity issuing any of the Pledged Collateral and any and all
                  rights of conversion, exchange, subscription or any other
                  rights, privileges or options pertaining to any of the Pledged
                  Collateral as if it were the absolute owner thereof,
                  including, without limitation, the right to exchange at its
                  discretion any and all of the Pledged Collateral upon the
                  merger, consolidation, reorganization, recapitalization or
                  other readjustment of any corporation, partnership or other
                  business entity issuing any of such Pledged Collateral or upon
                  the exercise by any such issuer or Secured Party of any right,
                  privilege or option pertaining to any of the Pledged
                  Collateral, and in connection therewith, to deposit and
                  deliver any and all of the Pledged Collateral with any
                  committee, depositary, transfer agent, registrar or other
                  designated agency upon such terms and conditions as it may
                  determine, all without liability except to account for
                  Property actually received by it, but Secured Party shall have
                  no duty to exercise any of the aforesaid rights, privileges or
                  options, and neither Secured Party nor any Lessor shall be
                  responsible for any failure to do so or delay in so doing;

                           (ii)       All rights of Debtor to exercise the
                  voting and other consensual rights which it would otherwise be
                  entitled to exercise pursuant to Section 4.16(a)(i) and to
                  receive the dividends, interest and other distributions which
                  it would otherwise be authorized to receive and retain
                  pursuant to Section 4.16(a)(ii) shall be suspended until such
                  Event of Default shall no longer exist, and all such rights
                  shall, until such Event of Default shall no longer exist,
                  thereupon become vested in Secured Party which shall thereupon
                  have the sole right to exercise such voting and other
                  consensual rights and to receive and hold as Pledged
                  Collateral such dividends, interest and other distributions;

                           (iii)      All dividends, interest and other
                  distributions which are received by Debtor contrary to the
                  provisions of this Section 4.16(b) shall be received in trust
                  for the benefit of Secured Party, shall be segregated from
                  other funds of Debtor and shall be forthwith paid over to
                  Secured Party as Collateral in the same form as so received
                  (with any necessary endorsement); and

<PAGE>

                           (iv)       Debtor shall execute and deliver (or cause
                  to be executed and delivered) to Secured Party all such
                  proxies and other instruments as Secured Party may request for
                  the purpose of enabling Secured Party to exercise the voting
                  and other rights which it is entitled to exercise pursuant to
                  this Section 4.16(b) and to receive the dividends, interest
                  and other distributions which it is entitled to receive and
                  retain pursuant to this Section 4.16(b). The foregoing shall
                  not in any way limit Secured Party's power and authority
                  granted pursuant to Section 5.1.

         Section 4.17        Transfers and Other Liens; Additional Investments.

                  (a)        Except as may be expressly permitted by the terms
         of the Restated Lease Agreement, Debtor shall not grant any option with
         respect to, exchange, sell or otherwise dispose of any of the
         Collateral or create or permit to exist any Lien upon or with respect
         to any of the Collateral except for the Liens created hereby and
         Permitted Encumbrances which are, in accordance with the Restated Lease
         Agreement, permitted to attach to such Collateral.

                  (b)        Debtor agrees that it will (i) cause its U.S.
         Subsidiaries not to issue any Capital Stock, notes or other securities
         or instruments in addition to or in substitution for any of the Pledged
         Shares, except (A) with prior written notice to Secured Party, to
         Debtor or (B) with the written consent of Secured Party, to any Person
         other than Debtor, (ii) pledge hereunder, immediately upon its
         acquisition (directly or indirectly) thereof, any and all such Capital
         Stock, notes or other securities or instruments, issued to Debtor or
         received in addition to or substituted for any of the Pledged
         Collateral, and (iii) promptly (and in any event within three Business
         Days) deliver to Secured Party an Amendment, duly executed by Debtor,
         in substantially the form of Exhibit D (an "Amendment"), in respect of
         such Capital Stock, notes or other securities or instruments, and
         deliver all certificates, notes or other securities or instruments
         representing or evidencing the same to Secured Party. Debtor hereby (1)
         authorizes Secured Party to attach each Amendment to this Agreement,
         and (2) agrees that all such Capital Stock, notes or other securities
         or instruments listed on any Amendment delivered to Secured Party shall
         for all purposes hereunder constitute Pledged Collateral.

         Section 4.18        Possession; Reasonable Care. Regardless of whether
a Default or an Event of Default has occurred or is continuing, Secured Party
shall have the right to hold in its possession all Instruments, Chattel Paper,
Pledged Collateral and other Collateral as to which possession thereof by
Secured Party is necessary or appropriate to perfect its Lien therein. Secured
Party may, from time to time, in its sole discretion, appoint one or more agents
(which in no case shall be Debtor or an Affiliate of Debtor) to hold physical
custody, for the account of Secured Party, of any or all of the Collateral.
Secured Party shall be deemed to have exercised reasonable care in the custody
and preservation of the Collateral in its possession if the Collateral is
accorded treatment substantially equal to that which Secured Party accords its
own Property, it being understood that Secured Party shall not have any
responsibility for (a) ascertaining or taking action with respect to calls,
conversions, exchanges, maturities, tenders or other matters relative to any
Collateral, whether or not

<PAGE>

Secured Party has or is deemed to have knowledge of such matters, or (b) taking
any necessary steps to preserve rights against any parties with respect to any
Collateral. Following the occurrence and during the continuation of an Event of
Default, Secured Party shall be entitled to take possession of all of the
Collateral.

         Section 4.19        Acknowledgment of Collateral Assignment of Deposit
Accounts. Debtor shall deliver to Secured Party, within 45 days of the execution
hereof and at any time as Secured Party may request thereafter, acknowledgment
by each financial institution in which any Deposit Account is held or maintained
that the collateral assignment of such Deposit Account has been recorded in the
books and records of such financial institution, and that Secured Party shall
have dominion and control over such Deposit Account, such acknowledgment to
be in form and substance satisfactory to Secured Party.

         Section 4.20        Statement of Account on Deposit Accounts. Debtor
shall, from time to time upon written request of Secured Party, provide to
Secured Party a copy of any requested statement of account on any Deposit
Account received by Debtor from the financial institution in which a Deposit
Account is held or maintained. At Secured Party's request, Debtor will use its
reasonable efforts to make such arrangements as are necessary or appropriate in
order to enable Secured Party to access such information by inquiry of an
officer or other representative of any such financial institution or via any
automated information system which may be maintained by such financial
institution.

         Section 4.21        Commercial Tort Claims. If any responsible officer
of Debtor shall at any time, whether or not Revised Article 9 is in effect in
any particular jurisdiction, become aware that Debtor has acquired (a) a
Commercial Tort Claim, as defined in Revised Article 9, in an amount greater
than $100,000 or (b) if and to the extent necessary to comply with the
succeeding proviso, other commercial tort claims, as defined in Revised Article
9, Debtor shall immediately notify Secured Party in a writing signed by Debtor
of the details thereof and grant to Secured Party in such writing a security
interest therein and in the proceeds thereof, all upon the terms of this
Agreement, with such writing to be in form and substance satisfactory to Secured
Party; provided, however, that the aggregate amount of Commercial Tort Claims in
which Secured Party shall not have a perfected security interest shall not at
any time exceed $250,000.

         Section 4.22        Letter-of-Credit Rights. If Debtor becomes the
beneficiary of a Letter of Credit, Debtor shall promptly, and in any event
within two (2) Business Days after becoming a beneficiary, notify Secured Party
thereof and enter into a tri-party agreement with Secured Party and the issuer
and/or confirmation bank with respect to Letter-of-Credit Rights assigning such
Letter-of-Credit Rights to Secured Party and directing all payment thereunder to
the Collection Account, all in form and substance reasonably satisfactory to
Secured Party.

         Section 4.23        Indemnification. In any suit, proceeding or action
brought by Secured Party relating to any Collateral for any sum owing with
respect thereto or to enforce any rights or claims with respect thereto, Debtor
will save, indemnify and keep Secured Party harmless from and against all
expense (including reasonable attorneys' fees and expenses), loss or damage
suffered by reason of any defense, setoff, counterclaim, recoupment or reduction
of liability whatsoever of the account

debtor or other Person obligated on the Collateral, arising out of a breach by
Debtor of any obligation thereunder or arising out of any other agreement,
indebtedness or liability at any time owing to, or in favor of, such obligor or
its successors from Debtor, except in the case of Secured Party, to the extent
such expense, loss, or damage is attributable solely to the gross negligence or
willful misconduct of Secured Party as finally determined by a court of
competent jurisdiction. All such obligations of Debtor shall be and remain
enforceable against and only against Debtor and shall not be enforceable against
Secured Party.

irrevocable power and authority in the name of Debtor or in its own name, to
take, after the occurrence and during the continuance of an Event of Default,

Secured Party at any time and from time to time deems necessary or desirable to
accomplish the purposes of this Agreement and, without limiting the generality
of the foregoing, Debtor hereby gives Secured Party the power and right on
behalf of Debtor and in its own name to do any of the following after the

                  (d)        (i) to direct account debtors and any other parties
         liable for any payment under any of the Collateral to make payment of
         any and all monies due and to become due thereunder directly to Secured
         Party or as Secured Party shall direct, provided, that Secured Party
         shall use reasonable efforts to give Debtor prior notice of the form of
         any such communication and Debtor shall have one (1) business day from
         receipt of such notice to provide input as to the form of such

         documents relating to the Collateral; (iv) to commence and prosecute
         any suit, action or proceeding at law or in equity in any court of
         competent jurisdiction to collect the Collateral or any part thereof

         defend any suit, action or proceeding brought against Debtor with
         respect to any Collateral; (vi) to settle, compromise or adjust any

         therewith, to give such discharges or releases as Secured Party may
         deem appropriate; (vii) to exchange any of the Collateral for other
         Property upon any merger, consolidation, reorganization,
         recapitalization or other readjustment of the issuer thereof and, in
         connection therewith, deposit any of the Collateral with any committee,
         depositary, transfer agent, registrar or other designated agency upon
         such terms as Secured Party may determine; (viii) to add or release any
         guarantor, indorser, surety or other party to any of the Collateral;

         compromise or adjust any claims under or pertaining to any of the
         Collateral (including, without limitation, claims under any policy of
         insurance); and (xiii) to sell, transfer, pledge, convey, make any
         agreement with respect to or otherwise deal with any of the Collateral
         as fully and completely as though Secured Party were the absolute owner
         thereof for all purposes, and to do, at Secured Party's option and
         Debtor's expense, at any time, or from time to time, all acts and
         things which Secured Party deems necessary to protect, preserve,
         maintain or realize upon the Collateral and Secured Party's security
         interest therein.

         This power of attorney is a power coupled with an interest and shall be
irrevocable until this Agreement is terminated in accordance with its terms.
Secured Party shall be under no duty to exercise or withhold the exercise of any
of the rights, powers, privileges and options expressly or implicitly granted to
Secured Party in this Agreement, and shall not be liable for any failure to do
so or any delay in doing so. Neither Secured Party nor any Person designated by
Secured Party shall be liable for any act or omission or for any error of
judgment or any mistake of fact or law except for gross negligence or willful
misconduct or as set forth in Section 4.18. This power of attorney is conferred
on Secured Party solely to protect, preserve, maintain and realize upon its
security interest in the Collateral. Secured Party shall not be responsible for
any decline in the value of the Collateral and shall not be required to take any
steps to preserve rights against prior parties or to protect, preserve or
maintain any Lien given to secure the Collateral.

         Section 5.2         Set-off. The Secured Party shall, after the
occurrence and during the continuation of an Event of Default, have the right to
set off and apply against the Obligations, at any time and without notice to
Debtor or Savvis, any and all deposits (general or special, time or demand,
provisional or final) or other sums at any time credited by or owing from the
Secured Party to Debtor and although such Obligations may be unmatured. The
rights and remedies of Secured Party and the

SECURITY AGREEMENT (Savvis Communications International, Inc.) - Page 29

Lessors hereunder are in addition to other rights and remedies (including,
without limitation, other rights of setoff) that Secured Party may have.

         Section 5.3         [INTENTIONALLY OMITTED]

         Section 5.4         Performance by Secured Party. If Debtor shall fail
to perform any covenant or agreement contained in this Agreement, Secured Party
may perform or attempt to perform such covenant or agreement on behalf of
Debtor. In such event, Debtor shall, at the request of Secured Party, promptly
pay any amount expended by Secured Party in connection with such performance or
attempted performance to Secured Party, together with interest thereon at the
default rate as described in Section 1.3 of the Restated Lease Agreement from
and including the date of such expenditure to but excluding the date such
expenditure is paid in full. Notwithstanding the foregoing, it is expressly
agreed that Secured Party shall not have any liability or responsibility for the
performance of any indebtedness, liability or obligation of Debtor under this
Agreement.

         Section 5.5         License. If no Event of Default shall have occurred
and be continuing, Debtor shall have the exclusive, non-transferable right and
license to use the Intellectual Property in the ordinary course of business and
the exclusive right to grant to other Persons licenses and sublicenses with
respect to the Intellectual Property for full and fair consideration. Debtor
agrees not to sell or assign its interest in, or grant any sublicense under, the
license granted under this Section 5.5 without the prior written consent of
Secured Party.

         Section 5.6         Change of Depository. In the event of the
termination by any financial institution in which any Deposit Account is
maintained of any agreement with or for the benefit of Secured Party, or if any
such financial institution shall fail to comply with any material provisions of
any such agreement or any instructions of Secured Party in accordance with any
such agreement or this Agreement, or if Secured Party determines in its
reasonable discretion that the financial condition of any such financial
institution has materially deteriorated, Debtor agrees to transfer the affected
Deposit Account(s) to another financial institution reasonably acceptable to
Secured Party and cause such substitute financial institution to execute such
agreements as Secured Party may require, in form and substance acceptable to
Secured Party, to ensure that Secured Party has a perfected, first priority
collateral assignment of or security interest in the Deposit Account(s) held
with such substitute financial institution. If any affected Deposit Account is a
lockbox account, Debtor agrees to notify its account debtors promptly to remit
all payments which were being sent to the terminated Deposit Account directly to
the substitute Deposit Account.

         Section 5.7         Collection of Deposit Accounts. After the
occurrence and during the continuation of an Event of Default, upon written
demand from Secured Party to any financial institution in which any of the
Deposit Accounts are maintained, each such financial institution is hereby
authorized and directed by Debtor to make payment directly to Secured Party of
the funds in or credited to the Deposit Accounts, or such part thereof as
Secured Party may request, and each such financial institution shall be fully
protected in relying upon the written statement of Secured Party that an Event
of Default has occurred and is continuing and that the Deposit Accounts are at
the time of such demand assigned hereunder and that Secured Party is entitled to
payment of the Obligations

SECURITY AGREEMENT (Savvis Communications International, Inc.) - Page 30
<PAGE>

therefrom. Secured Party's receipt for sums paid to it pursuant to such demand
shall be a full and complete release, discharge and acquittance to the
depository or other financial institution making such payment to the extent of
the amount so paid. Debtor hereby authorizes Secured Party, upon (a) the
occurrence and during the continuation of an Event of Default consisting of
Debtor's failure to make payment of any of the Obligations, or any part thereof,
or (b) any acceleration of the maturity of the Obligations upon the occurrence
of any Event of Default, each as provided in the Restated Lease Agreement, (i)
to withdraw, collect and receipt for any and all funds, securities or other
investments on deposit in or payable on the Deposit Accounts, (ii) on behalf of
Debtor to endorse the name of Debtor upon any checks, drafts or other
instruments payable to Debtor evidencing payment on the Deposit Accounts, and
(iii) to surrender or present for notation of withdrawal the passbook,
certificate or other documents issued to Debtor in connection with the Deposit
Accounts. No power granted herein to Secured Party by Debtor shall terminate
upon any disability of Debtor.

                                     -------

         Section 6.1         Rights and Remedies. If an Event of Default shall
have occurred and be continuing, Secured Party shall have the following rights
and remedies (subject to Section 6.3):

                  (a)        In addition to all other rights and remedies
         granted to Secured Party in this Agreement or in the Restated Lease
         Agreement or by applicable law, Secured Party shall have all of the
         rights and remedies of a secured party under the UCC (whether or not
         the UCC applies to the affected Collateral) and Secured Party may also,
         without notice except as specified below, sell the Collateral or any
         part thereof in one or more parcels at public or private sale, at any
         exchange, broker's board or at any of Secured Party's offices or
         elsewhere, for cash, on credit or for future delivery, and upon such
         other terms as Secured Party may deem commercially reasonable or
         otherwise as may be permitted by law. Without limiting the generality
         of the foregoing, Secured Party may (i) without demand or notice to
         Debtor, collect, receive or take possession of the Collateral or any
         part thereof and for that purpose Secured Party may enter upon any
         premises on which the Collateral is located and remove the Collateral
         therefrom or render it inoperable, and/or (ii) sell, lease or otherwise
         dispose of the Collateral, or any part thereof, in one or more parcels
         at a public or private sale or sales, at Secured Party's offices or
         elsewhere, for cash, on credit or for future delivery, and upon such
         other terms as Secured Party may deem commercially reasonable or
         otherwise as may be permitted by law. Secured Party shall have the
         right at any public sale or sales, and, to the extent permitted by
         applicable law, at any private sale or sales, to bid (which bid may be,
         in whole or in part, in the form of cancellation of indebtedness) and
         become a purchaser of the Collateral or any part thereof free of any
         right or equity of redemption on the part of Debtor, which right or
         equity of redemption is hereby expressly waived and released by Debtor.
         Upon the request of Secured Party, Debtor shall assemble the Collateral
         and make it available to Secured Party at any place designated by
         Secured Party that is reasonably convenient to Debtor and Secured
         Party. If and to the extent that Secured Party is required by
         applicable law to give prior written notice of the time and/or place of
         any such sale,

SECURITY AGREEMENT (Savvis Communications International, Inc.) - Page 31
<PAGE>


         Debtor agrees that Secured Party shall not be obligated to give more
         than five days prior written notice of the time and place of any public
         sale or of the time after which any private sale may take place and
         that such notice shall constitute reasonable notice of such matters.
         Secured Party shall not be obligated to make any sale of Collateral if
         it shall determine not to do so, regardless of the fact that notice of
         sale of Collateral may have been given. Secured Party may, without
         notice or publication, adjourn any public or private sale or cause the
         same to be adjourned from time to time by announcement at the time and
         place fixed for sale, and such sale may, without further notice, be
         made at the time and place to which the same was so adjourned. Debtor
         shall be liable for all expenses of retaking, holding, preparing for
         sale or the like, and all attorneys' fees, legal expenses and other
         costs and expenses incurred by Secured Party in connection with the
         collection of the Obligations and the enforcement of Secured Party's
         rights under this Agreement. Debtor shall remain liable for any
         deficiency if the Proceeds of any sale or other disposition of the
         Collateral applied to the Obligations are insufficient to pay the
         Obligations in full. Secured Party may apply the Collateral against the
         Obligations in such order and manner as Secured Party may elect in its
         sole discretion. Debtor waives all rights of marshaling, valuation and
         appraisal in respect of the Collateral. Any cash held by Secured Party
         as Collateral and all cash proceeds received by Secured Party in
         respect of any sale of, collection from or other realization upon all
         or any part of the Collateral may, in the discretion of Secured Party,
         be held by Secured Party as collateral for, and then or at any time
         thereafter applied in whole or in part by Secured Party against, the
         Obligations in such order as Secured Party shall select. Any surplus of
         such cash or cash proceeds and interest accrued thereon, if any, held
         by Secured Party and remaining after payment in full of all the
         Obligations shall be paid over to Debtor or to whomsoever may be
         lawfully entitled to receive such surplus; provided that Secured Party
         shall have no obligation to invest or otherwise pay interest on any
         amounts held by it in connection with or pursuant to this Agreement.

                  (b)        Secured Party may cause any or all of the
         Collateral held by it to be transferred into the name of Secured Party
         or the name or names of Secured Party's nominee or nominees.

                  (c)        Secured Party may exercise any and all rights and
         remedies of Debtor under or in respect of the Collateral, including,
         without limitation, any and all rights of Debtor to demand or otherwise
         require payment of any amount under, or performance of any provision
         of, any of the Collateral and any and all voting rights and corporate
         powers in respect of the Collateral.

                  (d)        Secured Party may collect or receive all money or
         Property at any time payable or receivable on account of or in exchange
         for any of the Collateral, but shall be under no obligation to do so.

                  (e)        On any sale of the Collateral, Secured Party is
         hereby authorized to comply with any limitation or restriction with
         which compliance is necessary, in the view of Secured

         Party's counsel, in order to avoid any violation of applicable law or
         in order to obtain any required approval of the purchaser or purchasers
         by any applicable Governmental Authority.

                  (f)        For purposes of enabling Secured Party to exercise
         its rights and remedies under this Section 6.1 and enabling Secured
         Party and its successors and assigns to enjoy the full benefits of the
         Collateral, Debtor hereby grants to Secured Party an irrevocable,
         nonexclusive license (exercisable without payment of royalty or other
         compensation to Debtor) to use, assign, license or sublicense any of
         the Intellectual Property that constitutes a part of the Collateral,
         including in such license reasonable access to all media in which any
         of the licensed items may be recorded or stored and all computer
         programs used for the completion or printout thereof. This license
         shall also inure to the benefit of all successors, assigns and
         transferees of Secured Party.

                  (g)        Secured Party may require that Debtor assign all of
         its right, title and interest in and to the Intellectual Property or
         any part thereof to Secured Party or such other Person as Secured Party
         may designate pursuant to documents satisfactory to Secured Party.

         Section 6.2         Registration Rights, Private Sales, Etc.

                  (a)        If Secured Party shall determine to exercise its
         right to sell all or any of the Pledged Shares pursuant to Section 6.1,
         Debtor agrees that, upon the request of Secured Party (which request
         may be made by Secured Party in its sole discretion), Debtor will, at
         its own expense:

                           (i)        execute and deliver, and use its best
                  efforts to cause each issuer of any of the Pledged Shares
                  contemplated to be sold and the directors and officers thereof
                  to execute and deliver, all such agreements, documents and
                  instruments, and do or cause to be done all such other acts
                  and things, as may be reasonably necessary or, in the
                  reasonable opinion of Secured Party, advisable to register
                  such Pledged Shares under the provisions of the Securities Act
                  (as hereinafter defined) and to cause the registration
                  statement relating thereto to become effective and to remain
                  effective for such period as prospectuses are required by law
                  to be furnished and to make all amendments and supplements
                  thereto and to the related prospectus which, in the opinion of
                  Secured Party, are necessary or advisable, all in conformity
                  with the requirements of the Securities Act of 1933, as
                  amended from time to time (the "Securities Act") and the rules
                  and regulations of the Securities and Exchange Commission
                  applicable thereto;

                           (ii)       if reasonably necessary or, in the
                  reasonable opinion of Secured Party, advisable, use its best
                  efforts to qualify such Pledged Shares under all applicable
                  state securities or "Blue Sky" laws and to obtain all
                  necessary governmental approvals for the sale of such Pledged
                  Shares, as requested by Secured Party;

SECURITY AGREEMENT (Savvis Communications International, Inc.) - Page 33
<PAGE>


                           (iii)      if reasonably necessary or, in the
                  reasonable opinion of Secured Party, advisable, cause each
                  such issuer to make available to its security holders, as soon
                  as practicable, an earnings statement which will satisfy the
                  provisions of Section 11(a) of the Securities Act;

                           (iv)       do or cause to be done all such other acts
                  and things as may be reasonably necessary or appropriate to
                  make such sale of the Pledged Shares or any part thereof valid
                  and binding and in compliance with applicable law; and

                           (v)        bear all reasonable costs and expenses,
                  including reasonable attorneys' fees, of carrying out its
                  obligations under this Section 6.2.

                  (b)        Debtor recognizes that Secured Party may be unable
         to effect a public sale of any or all of the Pledged Shares by reason
         of certain prohibitions contained in the Securities Act and applicable
         state securities laws but may be compelled to resort to one or more
         private sales thereof to a restricted group of purchasers who will be
         obliged to agree, among other things, to acquire such Pledged Shares
         for their own account for investment and not with a view to the
         distribution or resale thereof. Debtor acknowledges and agrees that any
         such private sale may result in prices and other terms less favorable
         to the seller than if such sale were a public sale and, notwithstanding
         such circumstances, agrees that any such private sale shall, to the
         extent permitted by law, be deemed to have been made in a commercially
         reasonable manner. Neither the Secured Party nor the Lessors shall be
         under any obligation to delay a sale of any of the Pledged Shares for
         the period of time necessary to permit the issuer of such securities to
         register such securities under the Securities Act or under any
         applicable state securities laws, even if such issuer would agree to do
         so.

                  (c)        Debtor further agrees to do or cause to be done, to
         the extent that Debtor may do so under applicable law, all such other
         acts and things as may be necessary to make such sales or resales of
         any portion or all of the Pledged Shares valid and binding and in
         compliance with any and all applicable laws, regulations, orders,
         writs, injunctions, decrees or awards of any and all courts,
         arbitrators or governmental instrumentalities, domestic or foreign,
         having jurisdiction over any such sale or sales, all at Debtor's
         expense. Debtor further agrees that a breach of any of the covenants
         contained in this Section 6.2 will cause irreparable injury to Secured
         Party and that Secured Party has no adequate remedy at law in respect
         of such breach and, as a consequence, agrees that each and every
         covenant contained in this Section 6.2 shall be specifically
         enforceable against Debtor, and Debtor hereby waives and agrees, to the
         fullest extent permitted by law, not to assert as a defense against an
         action for specific performance of such covenants that (i) Debtor's
         failure to perform such covenants will not cause irreparable injury to
         Secured Party or (ii) Secured Party has an adequate remedy at law in
         respect of such breach. Debtor further acknowledges the impossibility
         of ascertaining the amount of damages which would be suffered by
         Secured Party by reason of a breach of any of the covenants contained
         in this Section 6.2 and, consequently, agrees that, if Debtor shall
         breach any of such covenants and Secured Party shall sue for damages
         for such breach, Debtor shall pay to Secured Party, as liquidated
         damages and not as a penalty, an

SECURITY AGREEMENT (Savvis Communications International, Inc.) - Page 34
<PAGE>


         aggregate amount equal to the value of the Pledged Shares on the date
         Secured Party shall demand compliance with this Section 6.2.

                  (d)        DEBTOR HEREBY AGREES TO INDEMNIFY, PROTECT AND SAVE
         HARMLESS SECURED PARTY AND ANY CONTROLLING PERSONS THEREOF WITHIN THE
         MEANING OF THE SECURITIES ACT FROM AND AGAINST ANY AND ALL LIABILITIES,
         SUITS, CLAIMS, COSTS AND EXPENSES (INCLUDING REASONABLE COUNSEL FEES
         AND DISBURSEMENTS) ARISING UNDER THE SECURITIES ACT, THE SECURITIES AND
         EXCHANGE ACT OF 1934, AS AMENDED, ANY APPLICABLE STATE SECURITIES
         STATUTE, OR AT COMMON LAW, OR PURSUANT TO ANY OTHER APPLICABLE LAW IN
         CONNECTION WITH THE SALE OF ANY SECURITIES OR THE EXERCISE OF ANY OTHER
         RIGHT OR REMEDY OF SECURED PARTY, INSOFAR AS SUCH LIABILITIES, SUITS,
         CLAIMS, COSTS AND EXPENSES ARISE OUT OF, OR ARE BASED UPON, ANY UNTRUE
         STATEMENT OR ALLEGED UNTRUE STATEMENT OF A MATERIAL FACT MADE BY DEBTOR
         OR SAVVIS IN CONNECTION WITH THE SALE OR PROPOSED SALE OF ANY PART OF
         THE COLLATERAL, OR ARISES OUT OF, OR IS BASED UPON, THE OMISSION OR
         ALLEGED OMISSION BY DEBTOR OR SAVVIS TO STATE A MATERIAL FACT REQUIRED
         TO BE STATED IN CONNECTION THEREWITH OR NECESSARY TO MAKE THE
         STATEMENTS MADE NOT MISLEADING; PROVIDED, HOWEVER, THAT DEBTOR SHALL
         NOT BE LIABLE IN ANY SUCH CASE TO THE EXTENT THAT ANY SUCH LIABILITIES,
         SUITS, CLAIMS, COSTS AND EXPENSES ARISE OUT OF, OR ARE BASED UPON, ANY
         UNTRUE STATEMENT OR ALLEGED UNTRUE STATEMENT OR OMISSION OR ALLEGED
         OMISSION MADE IN RELIANCE UPON AND IN CONFORMITY WITH WRITTEN
         INFORMATION FURNISHED TO DEBTOR BY SECURED PARTY SPECIFICALLY FOR
         INCLUSION IN CONNECTION THEREWITH. THE FOREGOING INDEMNITY AGREEMENT IS
         IN ADDITION TO ANY INDEBTEDNESS, LIABILITY OR OBLIGATION THAT DEBTOR
         MAY OTHERWISE HAVE TO SECURED PARTY OR ANY CONTROLLING PERSON THEREOF.

         Section 6.3         Compliance with Laws. Notwithstanding anything to
the contrary contained in the Restated Lease Agreement or in any other
agreement, instrument or document executed by Debtor and delivered to Secured
Party, Secured Party will not take any action pursuant to this Agreement or any
document referred to herein which would constitute or result in any assignment
of any FCC License or any change of control (whether de jure or de facto) of
Debtor if such assignment of any FCC License or change of control would require,
under then existing law, the prior approval of the FCC or any other Governmental
Authority without first obtaining such prior approval of the FCC or other
Governmental Authority. Upon the occurrence of an Event of Default or at any
time thereafter during the continuance thereof, subject to the terms and
conditions of this Agreement, Debtor agrees to take any action which Secured
Party may request in order to obtain from the FCC or such other Governmental
Authority such approval as may be necessary to enable Secured Party to

exercise and enjoy the full rights and benefits granted to Secured Party by this
Agreement and the other documents referred to above, including specifically, at
the cost and expense of Debtor, the use of Debtor's best efforts to assist in
obtaining approval of the FCC or such other Governmental Authority for any
action or transaction contemplated by this Agreement for which such approval is
or shall be required by law, and specifically, without limitation, upon request,
to prepare, sign and file with the FCC or such other Governmental Authority the
assignor's or transferor's portion of any application or applications for
consent to the assignment of License or transfer of control necessary or
appropriate under the FCC's or such other Governmental Authority's rules and
regulations for approval of (a) any sale or other disposition of the Collateral
by or on behalf of Secured Party, or (b) any assumption by Secured Party of
voting rights in the Collateral effected in accordance with the terms of this
Agreement.

part of Secured Party to exercise and no delay in exercising, and no course of

any right, power or privilege under this Agreement preclude any other or further

rely upon them.

         Section 7.8         Counterparts. This Agreement may be executed in any
number of counterparts, each of which shall be deemed an original, but all of

hereby irrevocably waives any bonds and any surety or security relating thereto
that may be required by applicable law as an incident to such possession, and
waives any demand for possession prior to the commencement of any such suit or
action.

         Section 7.10        Severability. Any provision of this Agreement which
is determined by a court of competent jurisdiction to be prohibited or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent of such prohibition or unenforceability without invalidating the
remaining provisions of this Agreement, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.

         Section 7.11       Construction. Debtor and Secured Party acknowledge

warranty except as may be set forth in Section 4.18 and Section 5.1) such of the

PERMITTED BY APPLICABLE LAW, EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY AND
EXPRESSLY WAIVES ALL RIGHT TO A TRIAL BY JURY IN ANY ACTION, PROCEEDING OR

         THIS COPYRIGHT SECURITY AGREEMENT ("Agreement") is between Savvis

                                R E C I T A L S:
                                ---------------

         A.       Debtor and Secured Party have entered into that certain
Security Agreement dated as of March __, 2002 (as the same may be amended,

Lease Agreement:

                  (1)       each Copyright, each registration of a Copyright
         ("Copyright Registration"), and each application for registration of a
         Copyright ("Copyright Application"), including, without limitation,

                  (3)        all products and Proceeds of the foregoing,
         including, without limitation, any claim by Debtor against third
         parties for past, present, or future infringement or breach of any
         Copyright, Copyright Registration, Copyright Application, or Copyright
         License, including, without limitation, any Copyright, Copyright
         Registration, or Copyright License listed in Schedule 1 annexed hereto,
