                           the  other as being  closer to the  Arbitrator's  own
                           assessment of what an independent vendor would charge
                           for services similar in nature and volume to those to

                           this Agreement as an Addendum hereto.

                  authority  against or upon the Services.  In the  alternative,
                  SAVVIS  shall  provide  Bridge with a  certificate  evidencing
                  SAVVIS' exemption from payment of or liability for such taxes.

         4.3.     Bona fide disputes  concerning  invoices  shall be referred to
                  the parties' respective Contract Managers for resolution.  Any
                  amount  to  which  SAVVIS  is  entitled  as a  result  of  the
                  resolution of a billing dispute shall be credited  promptly to

                  hereof.

6.       TERMINATION BY SAVVIS

         6.1.     SAVVIS shall have the right to terminate this Agreement,  with
                  no  liability  to  Bridge  other  than for  charges  (less any
                  applicable  credits)  for  Services  provided  prior  to  such
                  termination, if:

                  (a)      SAVVIS  provides 10 days written notice of its intent
                           to  terminate  in the event that Bridge has failed to
                           perform or comply with or has  violated  any material
                           representation,    warranty,   term,   condition   or
                           obligation of Bridge under this Agreement, and Bridge
                           has failed to cure such failure or  violation  within
                           60 days after  receiving  notice thereof from SAVVIS;
                           or

                  (b)      Bridge   becomes  the  subject  of  a  voluntary   or
                           involuntary bankruptcy, insolvency, reorganization or
                           liquidation  proceeding,  makes an assignment for the
                           benefit of creditors, admits in writing its inability
                           to pay debts when due.

         6.2.     In the event that SAVVIS  exercises  this option,  Bridge will
                  continue to provide the Services in accordance with the terms,
                  conditions  and rates  herein  for a period of up to 12 months
                  after the effective date of termination.  If the Services have
                  not  completely  transitioned  from  Bridge  after 12  months,
                  Bridge will provide the Services at Bridge's then current list
                  rates.  Bridge and its successor  will  cooperate  with SAVVIS
                  until  the  Services  are   completely   migrated  to  another
                  provider.

                           provided SAVVIS with written notice thereof, provided
                           that  SAVVIS  shall  have 30 days  from  the  time it

9.       RIGHTS AND OBLIGATIONS OF BRIDGE

         9.1.     PROVISION OF THE  SERVICES.  Bridge shall provide the Services
                  at the Service Sites  designated by SAVVIS in accordance  with
                  the  Quality  of  Service  Standards  and other  terms of this
                  Agreement.

         9.2.     ACCESS AND SECURITY.  Bridge  personnel shall have such access
                  to SAVVIS' premises as is reasonably  necessary to provide the

                  Bridge  personnel  shall  comply  at all  times  with  SAVVIS'
                  reasonable security requirements.  SAVVIS shall have the right
                  immediately  to  terminate  the right of access of any  Bridge
                  personnel to any or all Service Sites should SAVVIS  determine
                  in its sole  discretion  that such  termination  is in SAVVIS'
                  best  interest,  provided  that SAVVIS shall not exercise this
                  right on grounds  unrelated to job  performance or in a manner
                  that obliges  Bridge to commit an unlawful act.  Unless Bridge
                  knew or should  reasonably have known that  particular  Bridge
                  personnel  would  be  barred  from a  Service  Site,  the time
                  allowed for any installation,  repair,  maintenance or similar
                  action that such  personnel  were to perform shall be extended
                  for  the  period  reasonably  required  by  Bridge  to  deploy
                  substitute personnel,  provided that Bridge shall use its best
                  efforts  to deploy  such  substitute  personnel  as quickly as
                  possible.  For purposes of this Section,  any subcontractor or
                  other agent of Bridge shall be treated as Bridge personnel.

                           by SAVVIS at no additional charge.

                  9.3.2.   Bridge  shall be liable  for  damages  to the  SAVVIS
                           Equipment caused by the negligence or willful acts or
                           omissions of Bridge's officers,  employees, agents or
                           contractors,  and for  damages  to  SAVVIS  Equipment
                           caused  by  the  use of  equipment  or  supplies  not
                           authorized by SAVVIS.

                  9.3.3.   Bridge shall neither  permit nor assist others to use
                           the SAVVIS  Equipment for any purpose other than that
                           for which  they are  intended,  and  Bridge  shall be
                           liable to SAVVIS for any  direct  costs  incurred  by
                           SAVVIS as a result of such use.

         9.4.     INSURANCE.

                  9.4.1.   At all  times  during  the  term of  this  Agreement,
                           Bridge  shall  maintain  for  itself,  its  officers,
                           employees,  agents and  representatives  insurance as
                           shall be provided for in an Addendum  mutually agreed
                           upon  by the  parties  in the  manner  set  forth  in
                           Section 1.2 hereof.

                  9.4.2.   Bridge shall furnish to SAVVIS, upon written request,
                           certificates   of  insurance  or  other   appropriate
                           documentation   (including  evidence  of  renewal  of
                           insurance)    evidencing   the   insurance   coverage
                           referenced  above,  naming  SAVVIS  as an  additional
                           insured.  Such  certificates  or other  documentation
                           shall include a proviso whereby 15 days prior written

                           Bridge or the applicable  insurer.  Such cancellation
                           or material  alteration  shall not relieve  Bridge of
                           its  continuing   obligation  to  maintain  insurance
                           coverage in accordance with this Section.

                  9.4.3.   In  lieu of all or  part  of the  insurance  coverage
                           specified  in this  Section,  Bridge may  self-insure
                           with respect to any insurance coverage,  except where
                           expressly prohibited by law.

         9.5.     REPRESENTATIONS AND WARRANTIES.

                  9.5.1.   Bridge  hereby  warrants  that the  Services  will be
                           provided  in  accordance  with the Quality of Service
                           Standards  throughout the term of this Agreement.  In
                           the event that  Bridge  fails to  provide  any of the
                           Services  in  accordance  with the Quality of Service
                           Standards,  SAVVIS  shall be entitled to recover from
                           Bridge (i) a refund of all amounts  paid by SAVVIS to
                           Bridge,  if any, for the  performance of the specific
                           Service that fails to meet the applicable  Quality of
                           Service  Standards,  plus  (ii)  the  costs  actually

                           provided by a third  party,  to the extent such costs
                           are in excess of the  amounts  that  SAVVIS  actually
                           paid,   or  would  have  paid,   to  Bridge  for  the
                           performance  of the  specific  Service  that fails to

                           WARRANTIES, EXPRESS OR IMPLIED, INCLUDING THE IMPLIED
                           WARRANTIES  OF  MERCHANTABILITY  AND  FITNESS  FOR  A
                           PARTICULAR PURPOSE.

10.      LIMITATIONS OF LIABILITY

                  incidental,  consequential,  exemplary,  reliance  or  special
                  damages, including damages for lost profits, regardless of the
                  form of  action  whether  in  contract,  indemnity,  warranty,
                  strict  liability or tort,  including  negligence  of any kind
                  with  respect  to the  Services  or other  conduct  under this
                  Agreement.

         10.2.    Nothing  contained in this Section shall limit either  party's
                  liability  to  the  other  for  (a)  willful  or   intentional
                  misconduct, or (b) injury or death, or damage to tangible real

                  rights) to  Services  (including  associated  programming  and
                  software)  are and shall remain with Bridge.  SAVVIS shall not
                  attempt to examine, copy, alter, reverse engineer,  decompile,
                  disassemble,  tamper with or otherwise  misuse such  Services,
                  programming and software.

                  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.

                  Confidential  Information  of the  other  party  to:  (a)  its
                  employees  and the  employees,  directors  and officers of its
                  Affiliates  as  necessary  to implement  this  Agreement;  (b)
                  employees,  agents or  representatives  of the other party; or
                  (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) shall be made only upon  prior
                  written  approval  of  the  other  party  and  subject  to the
                  appropriate  assurances that the recipient of such information
                  shall hold it in strict confidence.

         12.3.    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
                  written  consent,  shall  promptly  destroy it and provide the
                  other party with written certification of such destruction.

         12.4.    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.

         12.5.    Bridge  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
                  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 any other remedy available in law or equity.

         12.6.    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  and,  absent  the  other

                                       11
<PAGE>

                  party's  consent to such  disclosure,  use its best efforts to
                  resist,  and to assist  the  other  party in  resisting,  such
                  disclosure.  A party providing  another  party's  Confidential
                  Information to a court or other  governmental  authority shall
                  use  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.

         12.7.    The  provisions  of  Section  12.1  above  shall  not apply to
                  reasonably  necessary  disclosures  in or in  connection  with
                  filings  under any  securities  laws,  regulatory  filings  or
                  proceedings,  financial  disclosures  which in the good  faith
                  judgment  of  the  disclosing   party  are  required  by  law,
                  disclosures   required  by  court  or  tribunal  or  competent
                  jurisdiction,  or disclosures that may be reasonably necessary
                  in connection  with the  performance  or  enforcement  of this
                  Agreement or any of the obligations hereof; provided, however,
                  that if the  receiving  party would  otherwise  be required to
                  refer to or describe  any aspect of this  Agreement  in any of
                  the preceding circumstances, the receiving party shall use its
                  reasonable  efforts to take such steps as are available  under
                  such  circumstances   (such  as  by  providing  a  summary  or
                  synopsis)  to avoid  disclosure  of the  financial  terms  and
                  conditions of this Agreement.  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 than such due diligence review.

13.      INDEMNIFICATIONS

         13.1.    Bridge shall defend,  settle,  or otherwise  manage at its own
                  cost and expense any claim or action  against SAVVIS or any of
                  its  directors,  officers,  employees or assigns for actual or
                  alleged  infringement  of any  patent,  copyright,  trademark,
                  trade secret or similar  proprietary  right to the extent that
                  such claim or action  arises from  Bridge's  provision  of the
                  Services.  SAVVIS shall notify  Bridge  promptly in writing of
                  any such claim or suit and shall  cooperate  with  Bridge in a
                  reasonable   way  to  facilitate  the  settlement  or  defense
                  thereof.  Bridge  further  agrees to indemnify and hold SAVVIS
                  harmless from and against any and all  liabilities and damages
                  (whether  incurred  as the  result of a  judicial  decree or a
                  settlement),  and the costs and expenses  associated  with any
                  claim  or  action  of the  type  identified  in  this  Section
                  (including reasonable attorneys' fees).

         13.2.    If,  as a  consequence  of a  claim  or  action  of  the  kind
                  described  in Section  13.1,  SAVVIS' or  Bridge's  use of any
                  Service or related documentation is enjoined, Bridge shall, at
                  its option and  expense,  either:  (a)  procure for SAVVIS the
                  right   to   continue   using   the   affected   Services   or
                  documentation;  (b) modify such  Service or  documentation  so
                  that it is  non-infringing,  provided  that such  modification
                  does  not  affect  the   intended   use  of  the   Service  or
                  documentation as contemplated  hereunder;  or (c) upon written
                  notice to SAVVIS, substitute for such Service or documentation

                                       12
<PAGE>

                  a   comparable,   non-infringing   product   or   service   or
                  documentation.  If  Bridge  does not  take any of the  actions
                  described  in  clauses  (a),  (b) and  (c),  then  SAVVIS  may
                  terminate  any  affected  Service  pursuant  to Section 5, and
                  Bridge shall refund to SAVVIS any prepaid charges therefor.

14.      DISPUTES

         14.1.    Resolution  of  any  and  all  disputes  arising  from  or  in
                  connection  with this  Agreement,  whether  based on contract,
                  tort,   statute  or   otherwise,   including   disputes   over
                  arbitrability  and disputes in connection with claims by third
                  persons  ("DISPUTES")  shall be  exclusively  governed  by and
                  settled in accordance  with the provisions of this Section 14.
                  The  foregoing   shall  not  preclude   recourse  to  judicial
                  proceedings to obtain injunctive, emergency or other equitable
                  relief to enforce the provisions of this Agreement,  including
                  specific  performance,  and  to  decide  such  issues  as  are
                  required to be resolved in  determining  whether to grant such
                  relief. Resolution of Disputes with respect to claims by third
                  persons shall be deferred until any judicial  proceedings with
                  respect thereto are concluded.

         14.2.    The parties  hereby  agree to submit all  Disputes to rules of
                  arbitration of the American  Arbitration  Association  and the
                  Missouri  Uniform  Arbitration  Act (the  "RULES")  under  the
                  following  provisions,  which shall be final and binding  upon
                  the  parties,  their  successors  and  assigns,  and  that the
                  following  provisions  constitute a binding arbitration clause
                  under applicable law. Either party may serve process or notice
                  on the other in any  arbitration  or  litigation in accordance
                  with the notice  provisions  hereof.  The parties agree not to
                  disclose any information  regarding any Dispute or the conduct
                  of any arbitration hereunder,  including the existence of such
                  Dispute or such  arbitration,  to any  person or entity  other
                  than such employees or representatives of such party as have a
                  need to know.

         14.3.    Either party may commence proceedings hereunder by delivery of
                  written  notice  providing  a  reasonable  description  of the
                  Dispute to the other,  including a reference to this provision
                  (the "DISPUTE NOTICE").  Either party may initiate arbitration
                  of  a  Dispute  by   delivery  of  a  demand   therefor   (the
                  "ARBITRATION  DEMAND")  to the other  party not sooner than 60
                  calendar days after the date of delivery of the Dispute Notice
                  but at any time thereafter. The arbitration shall be conducted
                  in St. Louis, Missouri.

         14.4.    The arbitration  shall be conducted by three  arbitrators (the
                  "ARBITRATORS"),  one of whom shall be selected by Bridge,  one
                  by  SAVVIS,  and the third by  agreement  of the other two not
                  later than 10 days  after  appointment  of the first two,  or,
                  failing such agreement, appointed pursuant to the Rules. If an
                  Arbitrator  becomes  unable to  serve,  a  successor  shall be
                  selected  or  appointed  in  the  same  manner  in  which  the
                  predecessor Arbitrator was appointed.

         14.5.    The arbitration shall be conducted pursuant to such procedures
                  as the parties may agree or, in the absence of or failing such
                  agreement,   pursuant  to  the  Rules.   Notwithstanding   the

                                       13
<PAGE>

                  foregoing,  each party  shall  have the right to  inspect  the
                  books and  records  of the  other  party  that are  reasonably
                  related to the  Dispute,  and each party shall  provide to the
                  other,  reasonably  in advance of any  hearing,  copies of all
                  documents  which such party intends to present in such hearing
                  and the names and addresses of all witnesses  whose  testimony
                  such party intends to present in such hearing.

         14.6.    All hearings shall be conducted on an expedited schedule,  and
                  all proceedings shall be confidential. Either party may at its
                  expense make a stenographic record thereof.

         14.7.    The Arbitrators  shall complete all hearings not later than 90
                  calendar days after the Arbitrators' selection or appointment,
                  and shall make a final award not later than 30  calendar  days
                  thereafter.  The  Arbitrators  shall  apportion  all costs and
                  expenses of the Arbitration,  including the Arbitrators'  fees
                  and  expenses  of experts  ("ARBITRATION  COSTS")  between the
                  prevailing and non-prevailing  parties as the Arbitrators deem
                  fair and reasonable. In circumstances where a Dispute has been
                  asserted or defended  against on grounds that the  Arbitrators
                  deem manifestly  unreasonable,  the Arbitrators may assess all
                  Arbitration  Costs  against the  non-prevailing  party and may
                  include in the award the prevailing  party's  attorneys'  fees
                  and expenses in connection with any and all proceedings  under
                  this Section 14.

         14.8.    Either party may assert appropriate  statutes of limitation as
                  a defense in  arbitration;  provided,  that upon delivery of a
                  Dispute  Notice  any  such  statute  shall be  tolled  pending
                  resolution hereunder.

         14.9.    Pending the resolution of any dispute or  controversy  arising
                  under this  Agreement,  the parties shall  continue to perform
                  their respective obligations  hereunder,  and Bridge shall not
                  discontinue,  disconnect  or in any  other  fashion  cease  to
                  provide  all or any  substantial  portion of the  Services  to
                  SAVVIS unless otherwise directed by SAVVIS. This Section shall
                  not apply where SAVVIS is in default under this Agreement.

15.      FORCE MAJEURE

         15.1.    In no event shall  either party be liable to the other for any
                  failure  to  perform  hereunder  that  is due to  war,  riots,
                  embargoes, strikes or other concerted acts of workers (whether
                  of a party  hereto or of  others),  casualties,  accidents  or
                  other   causes  to  the  extent  that  such  failure  and  the
                  consequences  thereof  are  reasonably  beyond the control and
                  without the fault or negligence of the party claiming  excuse.
                  Each party shall, with the cooperation of the other party, use
                  reasonable  efforts to  mitigate  the extent of any failure to
                  perform and the adverse consequences thereof.

         15.2.    If Bridge cannot promptly provide a suitable  temporary Bridge
                  alternative  to  a  Service  subject  to  an  Interruption  in
                  connection  with the existence or a force  majeure  condition,
                  SAVVIS may, at its option and at its own cost,  contract  with

                                       14
<PAGE>

                  one or more third  parties  for (or provide for itself) any or
                  all affected Services for the shortest commercially  available
                  period likely to cover the reasonably expected duration of the
                  Interruption,  and  may  suspend  Bridge's  provision  of such
                  Services for such period.  Bridge shall not charge  SAVVIS for
                  any Services thus  suspended  during the period of suspension.
                  Bridge shall resume  provision of the suspended  Services upon
                  the later of the  termination or expiration of SAVVIS' legally
                  binding  commitments  under  contracts  with third parties for
                  alternative  services or the  cessation or remedy of the force
                  majeure condition.

         15.3.    In the event that a force majeure condition shall continue for
                  more than 60 days,  SAVVIS may cancel  the  affected  Services
                  with no further  liability  to Bridge  other than for Services
                  received  by  SAVVIS  prior  to the  occurrence  of the  force
                  majeure condition.

16.      GENERAL PROVISIONS

         16.1.    NO THIRD-PARTY BENEFICIARIES.  This Agreement shall not confer
                  any rights or  remedies  upon any person or entity  other than
                  the  parties and their  respective  successors  and  permitted
                  assigns.

         16.2.    ENTIRE  AGREEMENT.  This  Agreement  (including  the documents
                  referred to herein)  constitutes the entire agreement  between
                  the  parties   and   supersedes   any  prior   understandings,
                  agreements,  or  representations  by or between  the  parties,
                  written or oral,  to the extent they related in any way to the
                  subject matter hereof.

         16.3.    SUCCESSION AND  ASSIGNMENT.  This  Agreement  shall be binding
                  upon and inure to the benefit of the parties  named herein and
                  their respective  successors and permitted  assigns.  No party
                  may  assign  either  this  Agreement  or any  of  its  rights,
                  interests,  or obligations hereunder without the prior written
                  approval  of the  other  party,  which  consent  shall  not be
                  unreasonably withheld.

         16.4.    COUNTERPARTS.  This  Agreement  may be executed in one or more
                  counterparts,  each of which shall be deemed an  original  but
                  all of  which  together  will  constitute  one  and  the  same
                  instrument.

         16.5.    HEADINGS. The Section headings contained in this Agreement are
                  inserted for convenience  only and shall not affect in any way

                  requested,  postage  prepaid,  and  addressed  to the intended

offering  of Savvis  Common  Stock for sale by itself and  Bridge,  as a selling
stockholder,  through  a  firm  commitment  underwritten  public  offering  (the

     WHEREAS, the purchase  contemplated by the Purchase Agreement will (i) help
to assure the  successful  completion of the Offering on a timely basis and (ii)
strengthen  Bridge  financially,  better  assuring  its  ability to perform  its
obligations under the network transfer  agreements to be entered into by Savvis,
Bridge  and  certain  of their  respective  subsidiaries  concurrently  with the

     WHEREAS,  in order to induce WCAS VIII to enter into the Purchase Agreement
and consummate the transactions  contemplated thereby, Bridge and Savvis wish to
grant to WCAS VIII  certain  registration  rights with  respect to the shares of
Savvis Common Stock purchased by WCAS VIII pursuant thereto;

     NOW, THEREFORE, the parties hereto agree as follows:

     1.  SECTION  Certain  Definitions.  For  purposes  of this  Agreement,  the

shares of Savvis  common  stock  issuable  upon or issuable  with respect to the
Savvis  Common  Shares by way of stock  dividend or stock split or in connection

     SECTION 2. TRANSFERS OF RESTRICTED STOCK.

     (a)  NOTICE OF  TRANSFER.  If any  Investor  shall  Transfer  any shares of
Restricted  Stock,  notice of which  Transfer  is not  otherwise  required to be
delivered to Savvis hereunder, then within three days following the consummation

satisfactory)  for the  transferring  Investor  stating that such transaction is
exempt from registration under all applicable laws; PROVIDED,  HOWEVER,  that no
such opinion  shall be required in the case of a transfer by any Investor to its
affiliates or, if any such entity is a partnership or limited liability company,
a transfer by any Investor or its affiliates to its partners or members.

     STATEMENT  WITH  RESPECT  THERETO  UNDER  SAID  ACT AND  LAWS  OR (B)  SUCH
     TRANSACTION IS EXEMPT FROM SUCH REGISTRATION."

     SECTION 3. Registration Rights.

     (a) DEMAND REGISTRATION  RIGHTS.  Subject to paragraph (j) below, if Savvis
shall at any time be requested  by  Investors  holding a majority in interest of
the  Restricted  Stock,  in a  writing  that  states  the  number  of  shares of
Restricted Stock to be sold and the intended method of disposition thereof (each
such written request,  a "DEMAND  NOTICE"),  to effect a registration  under the
Securities Act of all or any portion of the  Restricted  Stock then held by such
requesting  Investors,  Savvis shall  immediately  notify in writing  (each such
notice,  a  "DEMAND  FURTHER  NOTICE")  each  other  Investor  (other  than  the
requesting Investors) of such proposed registration and shall use its reasonable
best efforts to register  under the Securities  Act (each such  registration,  a
"DEMAND  REGISTRATION"),  for  public  sale in  accordance  with the  method  of
disposition  specified in such Demand Notice, the number of shares of Restricted
Stock  specified in such Demand  Notice (plus the number of shares of Restricted
Stock specified in any written requests for registration of shares of Restricted
Stock  that are  received  from  other  Investors  (other  than  the  requesting
Investors)  within 30 days after  receipt by such  other  Investors  of a Demand
Further Notice). Savvis shall not be obligated pursuant to this paragraph (a) to
file and cause to become effective more than two Demand Registrations.

     (b) ADDITIONAL  SHORT-FORM  REGISTRATION RIGHTS. If Savvis becomes eligible
to use Form S-3 or a  successor  form,  Savvis  shall  use its  reasonable  best
efforts to continue to qualify at all times for registration on Form S-3 or such
successor  form.  Subject to paragraph  (j) below,  if (x) Savvis is eligible to
register  shares of Savvis Common Stock on Form S-3 or a successor  form and (y)
it is requested by any  Investor,  in a writing that states the number of shares
of Restricted  Stock to be sold and the intended  method of disposition  thereof
(each such written request,  a "SHORT FORM  REGISTRATION  NOTICE"),  to effect a
registration on Form S-3 or such successor form (a "SHORT FORM REGISTRATION") of
all or any portion of the Restricted Stock

                                       3
<PAGE>

then  held by such  requesting  Investor,  Savvis  shall  immediately  notify in
writing (each such notice,  a "SHORT FORM FURTHER  NOTICE") each other  Investor
(other than the requesting Investor) of such proposed registration and shall use
its reasonable  best efforts to register on Form S-3 or such successor form, for
public sale in accordance with the method of disposition specified in such Short
Form Further Notice,  the number of shares of Restricted Stock specified in such
Short  Form  Further  Notice  (plus the  number of  shares of  Restricted  Stock
specified in any written requests for registration of shares of Restricted Stock
that are received  from other  Investors  (other than the  requesting  Investor)
within 30 days  after  receipt by such other  Investors  of a Savvis  Short Form
Registration Notice); provided, no Investor or group of Investors shall have the
right to request a Short Form  Registration  unless the proposed  aggregate  net
proceeds to the  requesting  Investor(s)  (which shall be specified in the Short
Form Registration Request delivered in connection therewith) exceeds $5,000,000.

     (c) CERTAIN PROVISIONS RELATING TO REQUIRED REGISTRATIONS.  Notwithstanding
anything  to the  contrary  contained  in this  Agreement,  Savvis  shall not be
obligated to effect any registration  under paragraph (a) or (b) above except in
accordance with the following provisions:

          (i) the obligations of Savvis under paragraph (a) or (b) above, as the
     case may be, to effect a registration shall be deemed satisfied only when a
     registration  statement  covering  all of the  shares of  Restricted  Stock
     specified  in the  applicable  Demand  Notice  or Short  Form  Registration
     Notice, as the case may be, for sale in accordance with the intended method
     of  disposition  specified by the requesting  Investors,  shall have become
     effective  and,  if  such  method  of  disposition  is  a  firm  commitment
     underwritten  public  offering,  all such shares of Restricted  Stock shall
     have been sold pursuant thereto;

          (ii)  so  long  as  Savvis  has  provided  written  notice  of a prior
     registration  statement to each Investor in compliance  with  paragraph (d)
     below,  Savvis shall not be obligated  under  paragraph (a) or (b) above to
     file and cause to become  effective any  registration  statement so long as
     such prior registration  statement (other than a registration  statement on
     Form S-4 or Form S-8 promulgated under the Securities Act (or any successor
     forms  thereto)  or any  other  form  not  available  for  registering  the
     Restricted Stock for sale to the public) pursuant to which shares of common
     stock of  Savvis  are to be (or were to be) sold to the  public  was  filed
     prior to the  delivery  of the  applicable  Demand  Notice  or  Short  Form
     Registration  Notice,  as the  case  may be (and  such  prior  registration
     statement has not been withdrawn);  PROVIDED, Savvis shall not be permitted
     to delay a  requested  registration  under  paragraph  (a) or (b)  above in
     reliance  on this  paragraph  (c)(ii)  more  than  180 days  following  the
     effective date of such prior registration statement;

          (iii)  if  the  proposed  method  of  disposition   specified  by  the
     requesting  Investors shall be an underwritten public offering,  the number
     of shares of  Restricted  Stock to be included  in such an offering  may be
     reduced (PRO RATA among the Investors  seeking to include  Restricted Stock
     in such offering based on the number of shares of

                                       4
<PAGE>

     Restricted Stock so requested to be registered by such Investors) if and to
     the extent that, in the good faith opinion of the managing  underwriter  of
     such offering, inclusion of all shares would adversely affect the marketing
     (including, without limitation, the offering price) of the Restricted Stock
     to be sold;

          (iv) in the event that the proposed method of disposition specified by
     the requesting  Investors shall be an underwritten public offering,  Savvis
     shall  choose  the  managing  underwriter  (which  shall  be  a  nationally
     recognized  investment  banking firm  reasonably  acceptable to the (A) the
     requesting Investors and (B) Investors holding a majority of the Restricted
     Stock being sold in such offering);

          (v) Savvis shall be entitled to include in any  registration  referred
     to in  paragraph  (a) or (b)  above,  as the  case  may  be,  for  sale  in
     accordance  with the  method of  disposition  specified  by the  requesting
     Investors,  shares of common  stock of Savvis to be sold by Savvis  for its
     own  account,  except as and to the  extent  that,  in the  opinion  of the
     managing  underwriter of such offering (if such method of disposition shall
     be an underwritten public offering),  such inclusion would adversely affect
     the marketing  (including,  without limitation,  the offering price) of the
     Restricted Stock to be sold;

          (vi) except as provided in  paragraph  (c)(v)  above,  Savvis will not
     effect any other  registration  of its common  stock,  whether  for its own
     account or that of other holder(s) of common stock of Savvis, from the date
     of  receipt  of a Demand  Notice  or the date of  receipt  of a Short  Form
     Registration Notice, as the case may be, until the completion of the period
     of distribution of the registration contemplated thereby;

          (vii) if any Investor (other than the requesting  Investors)  requests
     that some or all of such Investor's  shares of Restricted Stock be included
     in an offering  initiated  pursuant to paragraph (a) or (b) above,  and the
     registration is to be, in whole or in part, an underwritten public offering
     of common  stock,  such request by such other  Investor  shall specify that
     such Investor's  Restricted  Stock is to be included in the underwriting on
     the same terms and conditions as the shares of Restricted  Stock  otherwise
     being sold through the underwriter; and

          (viii) if, while a registration is pending,  Savvis determines in good
     faith  that the  filing  of a  registration  statement  would  require  the
     disclosure of a material  transaction  or another set of material facts and
     such  disclosure  would  either  have a  material  adverse  effect  on such
     material  transaction  or Savvis and its  subsidiaries  (taken as a whole),
     then  Savvis  shall not be required  to effect a  registration  pursuant to
     paragraph  (a) or (b) above,  as the case may be,  until the earlier of (A)
     the date upon which such material information is otherwise disclosed to the
     public or ceases to be  material  and (B) 90 days after  Savvis  makes such
     good faith determination;  PROVIDED, Savvis shall not be permitted to delay
     a requested  registration  under  paragraph (a) or (b) above in reliance on
     this  paragraph  (c)(viii) more than twice or for more than an aggregate of
     90 days in any consecutive twelve-month period.

                                       5
<PAGE>

     (d)  PIGGYBACK  REGISTRATION  RIGHTS.  If at any time  Savvis  proposes  to
register  any of its  common  stock  under  the  Securities  Act for sale to the
public, whether for its own account or for the account of other security holders
or both (other than a registration on Form S-4 or Form S-8 promulgated under the
Securities Act (or any successor  forms thereto) or any other form not available
for  registering  the  Restricted  Stock for sale to the  public),  it will give
written  notice  (each such  notice a  "PIGGYBACK  NOTICE") at such time to each
Investor of its  intention to do so.  Subject to paragraph  (j) below,  upon the
written  request of any  Investor,  given  within 30 days after  receipt by such
holder of the Piggyback  Notice,  to register any of its Restricted Stock (which
request shall state the amount of Restricted  Stock to be so registered  and the
intended  method of disposition  thereof),  Savvis will use its reasonable  best
efforts to cause the Restricted Stock, as to which  registration shall have been
so requested, to be included in the securities to be covered by the registration
statement  proposed to be filed by Savvis, all to the extent requisite to permit
the sale or other  disposition by such Investor (in accordance  with its written
request) of such Restricted Stock so registered;  PROVIDED, nothing herein shall
prevent Savvis from abandoning or delaying such registration at any time. In the
event that any registration referred to in this paragraph (d) shall be, in whole
or in part,  an  underwritten  public  offering of common  stock of Savvis,  any
request by an Investor  pursuant to this  paragraph  (d) to register  Restricted
Stock shall specify either that (i) such  Restricted  Stock is to be included in
the underwriting on the same terms and conditions as the shares of Savvis common
stock otherwise being sold through  underwriters under such registration or (ii)
such Restricted Stock is to be sold in the open market without any underwriting,
on terms and conditions  comparable to those normally applicable to offerings of
common  stock in  reasonably  similar  circumstances.  The  number  of shares of
Restricted Stock to be included in such an underwritten  offering may be reduced
(PRO RATA  among the  requesting  Investors  based  upon the number of shares of
Restricted  Stock  so  requested  to be  registered  or PRO RATA  among  all the
requesting  stockholders  based  upon the  number of  shares of common  stock of
Savvis so requested to be registered if  stockholders  other than Investors also
request to be included) if and to the extent that the  managing  underwriter  of
such  offering  shall be of the good faith  opinion  that such  inclusion  would
adversely  affect the marketing  (including,  without  limitation,  the offering
price) of the securities to be sold by Savvis therein,  or by the other security
holders for whose benefit the registration statements has been filed.

     (e) HOLDBACK AGREEMENT.  Notwithstanding anything to the contrary contained
in  this  Agreement,  (i) if  there  is a firm  commitment  underwritten  public
offering of securities of Savvis pursuant to a registration  covering Restricted
Stock  and an  Investor  does  not  elect to sell  his  Restricted  Stock to the
underwriters  of Savvis's  securities in  connection  with such  offering,  such
Investor shall refrain from selling such  Restricted  Stock during the period of
distribution of Savvis's securities by such underwriters and the period in which
the  underwriting  syndicate  participates in the after market;  PROVIDED,  such
Investor  shall,  in any  event,  be  entitled  to  sell  its  Restricted  Stock
commencing on the 180th day after the effective date of such registration

                                       6
<PAGE>

statement;  and (ii) if there is a firm commitment  underwritten public offering
of securities  of Savvis by Savvis,  each  Investor  agrees that,  except to the
extent otherwise permitted to participate in such offering pursuant to paragraph
(d) above, upon the request of the managing  underwriter in such offering,  such
Investor  shall not sell Savvis  Common Stock held by such Investor for a period
of 180 days  from the  effective  date of the  registration  statement  relating
thereto.

     (f) CERTAIN REGISTRATION PROCEDURES.  If and whenever Savvis is required by
the  provisions of this Section 3 to use its  reasonable  best efforts to effect
the  registration of Restricted  Stock under the Securities Act, Savvis will, as
expeditiously as possible:

          (i) prepare (and afford counsel for the selling  Investors  reasonable
     opportunity  to review and comment  thereon) and file with the Commission a
     registration  statement  with  respect  to  such  securities  and  use  its
     reasonable best efforts to cause such registration  statement to become and
     remain  effective for the period of the distribution  contemplated  thereby
     (determined as hereinafter provided);

          (ii) prepare (and afford counsel for the selling Investors  reasonable
     opportunity  to review and comment  thereon)  and file with the  Commission
     such  amendments  and  supplements to such  registration  statement and the
     prospectus  used in  connection  therewith as may be necessary to keep such
     registration   statement   effective   for  the   period  of   distribution
     contemplated  thereby  (determined as  hereinafter  provided) and as comply
     with the provisions of the  Securities Act with respect to the  disposition
     of  all  Restricted  Stock  covered  by  such  registration   statement  in
     accordance with the selling  Investors'  intended method of disposition set
     forth in such registration statement for such period;

          (iii) furnish to each selling  Investor and to each  underwriter  such
     number of copies of the registration  statement and the prospectus included
     therein  (including,  without limitation,  each preliminary  prospectus) as
     such persons may reasonably  request in order to facilitate the public sale
     or other  disposition of the Restricted Stock covered by such  registration
     statement;

          (iv) use its  reasonable  best  efforts to  register  or  qualify  the
     Restricted  Stock  covered  by  such   registration   statement  under  the
     securities  or blue  sky  laws  of such  jurisdictions  as the  sellers  of
     Restricted Stock or, in the case of an underwritten  public  offering,  the
     managing underwriter,  shall reasonably request;  PROVIDED, Savvis will not
     be  required to (x) qualify  generally  to do business in any  jurisdiction
     where it would not otherwise be required to qualify but for this  paragraph
     (iv),  (y)  subject  itself to  taxation  in any such  jurisdiction  or (z)
     consent to general service of process in any jurisdiction;

          (v) immediately  notify each selling Investor under such  registration
     statement  and each  underwriter,  at any time when a  prospectus  relating
     thereto is required to be

                                       7
<PAGE>

     delivered  under the  Securities  Act, of the  happening  of any event as a
     result of which the prospectus contained in such registration statement, as
     then in effect, includes an untrue statement of a material fact or omits to
     state any material fact required to be stated  therein or necessary to make
     the  statements  therein not  misleading in the light of the  circumstances
     then existing,  and each Investor agrees to refrain from further using such
     prospectus upon receipt of such notice;

          (vi) use its reasonable best efforts (if the offering is underwritten)
     to  furnish,  at the  request  of any  selling  Investor,  on the date that
     Restricted Stock is delivered to the underwriters for sale pursuant to such
     registration: (A) an opinion dated such date of counsel representing Savvis
     for the purposes of such registration, addressed to the underwriters and to
     such selling Investor,  stating that such registration statement has become
     effective  under the  Securities  Act and that (1) to the best knowledge of
     such counsel,  no stop order suspending the effectiveness  thereof has been
     issued and no  proceedings  for that  purpose have been  instituted  or are
     pending or  contemplated  under the  Securities  Act, (2) the  registration
     statement,  the  related  prospectus,  and  each  amendment  or  supplement
     thereof,  comply as to form in all material  respects with the requirements
     of the  Securities  Act and the  applicable  rules and  regulations  of the
     Commission  thereunder (except that such counsel need express no opinion as
     to financial statements, the notes thereto, and the financial schedules and
     other  financial and  statistical  data contained  therein) and (3) to such
     other   effects  as  may   reasonably  be  requested  by  counsel  for  the
     underwriters or by such selling  Investor or its counsel,  and (B) a letter
     dated such date from the independent public accountants retained by Savvis,
     addressed to the  underwriters,  stating that they are  independent  public
     accountants  within the  meaning  of the  Securities  Act and that,  in the
     opinion of such accountants, the financial statements of Savvis included in
     the  registration  statement  or  the  prospectus,   or  any  amendment  or
     supplement  thereof,  comply as to form in all material  respects  with the
     applicable  accounting  requirements of the Securities Act, and such letter
     shall additionally cover such other financial matters  (including,  without
     limitation,  information as to the period ending no more than five business
     days prior to the date of such letter) with respect to the  registration in
     respect of which such  letter is being given as such  underwriters  or such
     selling Investor may reasonably request; and

          (vii) make  available  for  inspection by each selling  Investor,  any
     underwriter participating in any distribution pursuant to such registration
     statement,  and any attorney,  accountant  or other agent  retained by such
     selling Investor or underwriter, all financial and other records, pertinent
     corporate  documents and properties of Savvis, and cause Savvis's officers,
     directors and employees to supply all information  reasonably  requested by
     any such selling Investor,  underwriter,  attorney,  accountant or agent in
     connection  with  such  registration  statement  and  permit  such  selling
     Investor,  attorney,  accountant or agent to participate in the preparation
     of such registration statement.

For  purposes  of  paragraphs  (f)(i) and (f)(ii)  above (as well as  paragraphs
(c)(vi) and(e) above),  the "PERIOD OF  DISTRIBUTION"  of Restricted  Stock in a
firm  commitment  underwritten  public  offering shall be deemed to extend until
each underwriter has completed the  distribution of all securities  purchased by
it, and the period of distribution of Restricted Stock in any other registration
shall be  deemed  to  extend  until  the sale of all  Restricted  Stock  covered
thereby,  but in either case,  such period shall not extend beyond the 180th day
(or, in the case of paragraph  (c)(vi) above,  the 90th day) after the effective
date of the registration statement filed in connection therewith.

     (g)   INFORMATION   FROM  SELLING   INVESTORS.   In  connection  with  each
registration  hereunder,  Investors  selling  Restricted  Stock will  furnish to
Savvis in writing such  information  with respect to themselves and the proposed
distribution  by them as  shall be  reasonably  necessary  in  order  to  assure
compliance with federal and applicable state securities laws.

     (h) UNDERWRITING AGREEMENT. In connection with any registration pursuant to
this Section 3 that covers an underwritten public offering, Savvis and Investors
selling  Restricted  Stock (and Bridge,  to the extent requested by the managing
underwriter)  each agree to enter  into a written  agreement  with the  managing
underwriter  selected in the manner herein  provided in such form and containing
such  provisions  as are  customary  in the  securities  business  for  such  an
arrangement  between major underwriters,  selling  stockholders and companies of
Savvis' and Bridge's size and investment stature;  PROVIDED,  (i) such agreement
shall not contain any such provision  applicable to Savvis which is inconsistent
with the provisions hereof and (ii) the time and place of the closing under said
agreement   shall  be  as  mutually  agreed  upon  among  Savvis  such  managing
underwriter and, except in the case of a registration  pursuant to paragraph (d)
above,  Investors  holding a majority of the Restricted Stock being sold in such
offering.

     (i)  EXPENSES.  Bridge  will  pay all  Registration  Expenses  incurred  in
complying with Section 3 of this  Agreement.  All Selling  Expenses  incurred in
connection  with any registered  offering of securities  that,  pursuant to this
Section  3,  includes  Restricted  Stock,  shall be  borne by the  participating
sellers in  proportion  to the number of shares sold by each, or by such persons
other than Savvis  (except to the extent  Savvis  shall be a seller) as they may
agree.  All expenses  incident to  performance  of or  compliance by Savvis with
Section 3 hereof, including,  without limitation, all Commission, stock exchange
or National  Association of Securities Dealers,  Inc. ("NASD")  registration and
filing  fees  (including,  without  limitation,  fees and  expenses  incurred in
connection  with the  listing  of the common  stock of Savvis on any  securities
exchange or exchanges),  printing,  distribution and related expenses,  fees and
disbursements of counsel and independent public accountants for Savvis, all fees
and expenses  incurred in connection with  compliance  with state  securities or
blue sky laws and the  rules of the NASD or any  securities  exchange,  transfer
taxes and fees of transfer  agents and  registrars,  but  excluding  any Selling
Expenses, are herein called "REGISTRATION  EXPENSES". All underwriting discounts
and selling  commissions  applicable to the sale of Restricted  Stock are herein
called "SELLING EXPENSES".

     (j)  AVAILABILITY  OF RULE  144(d).  Each  Investor  agrees that during any
period  in  which  such  Investor  is  eligible  to sell  all of its  shares  of
Restricted Stock pursuant to Rule 144(k), such Investor shall not be entitled to
invoke or otherwise  participate with respect to the registration rights granted
pursuant to paragraphs (a), (b) and (d) above.

     SECTION 4. INDEMNIFICATION  RIGHTS AND OBLIGATIONS IN RESPECT OF REGISTERED
OFFERINGS OF RESTRICTED STOCK.

     (a)  SAVVIS  INDEMNIFICATION  OF  SELLING  INVESTORS.  In  the  event  of a
registration of any of the Restricted Stock under the Securities Act pursuant to
Section 3 of this Agreement, Savvis will indemnify and hold harmless each seller
of Restricted Stock thereunder and each other person,  if any, who controls such
seller within the meaning of the  Securities  Act,  against any losses,  claims,
damages or  liabilities,  joint or several,  (or actions in respect  thereof) to
which such seller or controlling  person may become subject under the Securities
Act or otherwise,  insofar as such losses,  claims,  damages or liabilities  (or
actions in respect  thereof) arise out of or are based upon any untrue statement
or alleged untrue  statement of any material fact contained in any  registration
statement under which such Restricted  Stock was registered under the Securities
Act, any preliminary  prospectus or final prospectus  contained therein,  or any
amendment or supplement  thereof, or arise out of or are based upon the omission
or alleged  omission  to state  therein a material  fact  required  to be stated
therein or necessary to make the  statements  therein not  misleading,  and will
reimburse  each such  seller and each such  controlling  person for any legal or
other expenses  reasonably  incurred by them in connection with investigating or
defending any such loss, claim, damage,  liability or action;  PROVIDED,  Savvis
will not be  liable in any such case if and to the  extent  that any such  loss,
claim,  damage,  liability  or action  arises  out of or is based upon an untrue
statement or alleged untrue statement or omission or alleged omission so made in
conformity with information  furnished by such seller or such controlling person
in writing specifically for use in such registration statement or prospectus.

     (b)  SELLING  INVESTOR  INDEMNIFICATION  OF SAVVIS  AND THE  OTHER  SELLING
STOCKHOLDERS.  In the event of a  registration  of any of the  Restricted  Stock
under the Securities Act pursuant to Section 3 of this Agreement, each seller of
such Restricted Stock thereunder,  severally and not jointly, will indemnify and
hold  harmless  Savvis and each person,  if any, who controls  Savvis within the
meaning of the Securities Act, each officer of Savvis who signs the registration
statement,  each  director  of  Savvis,  each  underwriter  and each  person who
controls  any  underwriter  within the meaning of the  Securities  Act, and each
other  seller of  Restricted  Stock and each person who  controls any such other
seller of Restricted Stock, against all losses,  claims, damages or liabilities,
joint or  several,  (or  actions in  respect  thereof)  to which  Savvis or such
officer or director or  underwriter  or other seller or  controlling  person may
become subject under the  Securities  Act or otherwise,  insofar as such losses,
claims,  damages or liabilities (or actions in respect  thereof) arise out of or
are based upon any untrue  statement or alleged untrue statement of any material
fact contained in the  registration  statement under which such Restricted Stock
was registered  under the Securities  Act, any  preliminary  prospectus or final
prospectus  contained therein,  or any amendment or supplement thereof, or arise
out of or are based upon the

                                       10
<PAGE>

omission or alleged  omission to state  therein a material  fact  required to be
stated therein or necessary to make the statements  therein not misleading,  and
will reimburse Savvis and each such officer, director, underwriter, other seller
of  Restricted  Stock and  controlling  person  for any legal or other  expenses
reasonably  incurred by them in connection with  investigating  or defending any
such loss, claim,  damage,  liability or action;  PROVIDED,  such seller will be
liable  hereunder in any such case if and only to the extent that any such loss,
claim,  damage,  liability  or action  arises  out of or is based upon an untrue
statement or alleged  untrue  statement or omission or alleged  omission made in
reliance upon and in conformity with information  pertaining to such seller,  as
such, furnished in writing to Savvis by such seller specifically for use in such
registration statement or prospectus;  PROVIDED,  FURTHER, the liability of each
seller  hereunder  shall be limited to the  proportion of any such loss,  claim,
damage,  liability or expense which is equal to the  proportion  that the public
offering price of shares sold by such seller under such  registration  statement
bears to the total public offering price of all securities sold thereunder,  but
not to exceed the  proceeds  (net of  underwriting  discounts  and  commissions)
received  by such  seller  from the sale of  Restricted  Stock  covered  by such
registration statement.

     (c)  INDEMNIFICATION  PROCEDURES.  Promptly after receipt by an indemnified
party hereunder of notice of the  commencement of any action,  such  indemnified
party  shall,  if a  claim  in  respect  thereof  is  to  be  made  against  the
indemnifying party hereunder,  notify the indemnifying party in writing thereof,
but the omission so to notify the  indemnifying  party shall not relieve it from
any liability which it may have to any  indemnified  party other than under this
Section 4. In case any such  action  shall be brought  against  any  indemnified
party and it shall notify the indemnifying  party of the  commencement  thereof,
the indemnifying party shall be entitled to participate in and, to the extent it
shall  wish,  to  assume  and   undertake  the  defense   thereof  with  counsel
satisfactory to such indemnified  party, and, after notice from the indemnifying
party to such  indemnified  party of its election so to assume and undertake the
defense thereof,  the indemnifying party shall not be liable to such indemnified
party under this Section 4 for any legal expenses  subsequently incurred by such
indemnified  party in connection  with the defense thereof other than reasonable
costs of investigation and of liaison with counsel so selected; PROVIDED, if the
defendants  in any such  action  include  both  the  indemnified  party  and the
indemnifying  party and the indemnified  party shall have  reasonably  concluded
that there may be reasonable  defenses  available to it which are different from
or additional to those available to the indemnifying  party, or if the interests
of the indemnified party reasonably may be deemed to conflict with the interests
of the indemnifying  party, the indemnified party shall have the right to select
a  separate  counsel  and  to  assume  such  legal  defenses  and  otherwise  to
participate  in the defense of such  action,  with the expenses and fees of such
separate  counsel  and  other  expenses  related  to  such  participation  to be
reimbursed by the indemnifying party as incurred. Notwithstanding the foregoing,
any indemnified party shall have the right to retain its own counsel in any such
action,  but the fees and  disbursements of such counsel shall be at the expense
of such indemnified party unless (i) the indemnifying party shall have failed to
retain counsel for the indemnified  person as aforesaid or (ii) the indemnifying
party and such indemnified  party shall have mutually agreed to the retention of
such  counsel.  It is  understood  that the  indemnifying  party  shall not,  in
connection  with any action or  related  actions  in the same  jurisdiction,  be
liable for the fees and

                                       11
<PAGE>

disbursements  of more than one separate firm qualified in such  jurisdiction to
act as counsel for the indemnified  party. The  indemnifying  party shall not be
liable  for any  settlement  of any  proceeding  effected  without  its  written
consent,  but if settled with such  consent or if there be a final  judgment for
the plaintiff,  the indemnifying party agrees to indemnify the indemnified party
from and against any loss or liability by reason of such settlement or judgment.
The  indemnification of underwriters  provided for in this Section 4 shall be on
such other terms and  conditions  as are at the time  customary  and  reasonably
required by such underwriters.  In that event the indemnification of the sellers
of  Restricted  Stock in such  underwriting  shall at the  sellers'  request  be
modified to conform to such terms and conditions.

     (d) CONTRIBUTION. If the indemnification provided for in paragraphs (a) and
(b) of this  Section  4 is  unavailable  or  insufficient  to hold  harmless  an
indemnified  party  under such  paragraphs  in respect  of any  losses,  claims,
damages or liabilities or actions in respect thereof  referred to therein,  then
each  indemnifying  party shall in lieu of indemnifying  such indemnified  party
contribute to the amount paid or payable by such  indemnified  party as a result
of such losses,  claims,  damages,  liabilities or actions in such proportion as
appropriate to reflect the relative fault of Savvis and Bridge, on the one hand,
and the underwriters and the sellers of such Restricted  Stock, on the other, in
connection  with the  statements  or  omissions  which  resulted in such losses,
claims, damages,  liabilities or actions as well as any other relevant equitable
considerations,  including,  without limitation,  the failure to give any notice
under  paragraph (c) above.  The relative fault shall be determined by reference
to,  among other  things,  whether the untrue or alleged  untrue  statement of a
material fact relates to  information  supplied by Savvis or Bridge,  on the one
hand,  or the  underwriters  and the sellers of such  Restricted  Stock,  on the
other, and to the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission. Savvis, Bridge and
each of you  agree  that it would  not be just and  equitable  if  contributions
pursuant to this paragraph were determined by pro rata  allocation  (even if all
of the  sellers of such  Restricted  Stock  were  treated as one entity for such
purpose) or by any other method of allocation  which did not take account of the
equitable considerations referred to above in this paragraph. The amount paid or
payable by an  indemnified  party as a result of the  losses,  claims,  damages,
liabilities or action in respect  thereof,  referred to above in this paragraph,
shall be deemed to include any legal or other  expenses  reasonably  incurred by
such  indemnified  party in connection with  investigating or defending any such
action or claim.  Notwithstanding the provisions of this paragraph,  the sellers
of such  Restricted  Stock  shall not be required  to  contribute  any amount in
excess of the amount,  if any, by which the total price at which the  Restricted
Stock sold by each of them was  offered to the public  exceeds the amount of any
damages which they would have  otherwise  been required to pay by reason of such
untrue or alleged untrue  statement or omission.  No person guilty of fraudulent
misrepresentations  (within the meaning of Section 11(f) of the Securities Act),
shall be  entitled  to  contribution  from any  person who is not guilty of such
fraudulent misrepresentation.

     SECTION 5. RULE 144.  Savvis agrees with the Investors  that from and after
the  consummation of the Offering it shall file any and all reports  required to
be filed by it under the

                                       12
<PAGE>

Securities Act and the Exchange Act and the rules and regulations adopted by the
Commission  thereunder,  or, if Savvis is not required to file any such reports,
it shall, upon the written request of any Investor, make publicly available such
information  as is  necessary  to permit  sales  pursuant  to Rule 144 under the
Securities Act. Upon the written request of any Investor,  Savvis shall promptly
furnish to such Investor a written statement by Savvis as to its compliance with
the reporting requirements set forth in this Section 5.

     SECTION  6. DURATION OF AGREEMENT.  This Agreement shall survive so long as
any Investor owns Restricted Stock.

     SECTION 7. REPRESENTATIONS AND WARRANTIES. Each party hereto, severally and
not jointly, represents and warrants to the other parties hereto as follows:

          (i) such party has the corporate or  partnership  power and authority,
     as the case may be, to execute and deliver  this  Agreement  and to perform
     its obligations hereunder. The execution,  delivery and performance by such
     party  of  this  Agreement  have  been  duly  authorized  by all  requisite
     corporate or  partnership  action,  as the case may be, on the part of such
     party and will not (i) violate any provision of law, any order of any court
     or other  agency  of  government,  the  charter  and  other  organizational
     documents of such party,  or any provision of any  indenture,  agreement or
     other  instrument by which such party or any of such party's  properties or
     assets is bound;  (ii) conflict  with,  result in a breach of or constitute
     (with  due  notice  or  lapse  of time or both) a  default  under  any such
     indenture,  agreement or other instrument;  or (iii) result in the creation
     or imposition of any lien,  charge or encumbrance of any nature upon any of
     the properties or assets of such party; and

          (ii) this Agreement has been duly executed and delivered by such party
     and  constitutes  a legal,  valid  and  binding  agreement  of such  party,
     enforceable against such party in accordance with its terms, subject, as to
     enforcement   of   remedies,   to   applicable   bankruptcy,    insolvency,
     reorganization,  moratorium  and  similar  laws from time to time in effect
     affecting the  enforcement  of creditors'  rights  generally and to general
     principles of equity.

          SECTION 8. Miscellaneous.

     (a)  ADDITIONAL  REGISTRATION  RIGHTS.  Without  the  consent of  Investors
holding at least a majority of the shares of Restricted Stock then  outstanding,
Savvis  shall not grant any  registration  rights to any other  person  that are
inconsistent or conflict with the registration rights granted hereunder.

     (b) HEADINGS.  Headings of sections and  paragraphs  of this  Agreement are
inserted  for   convenience   of  reference   only  and  shall  not  affect  the
interpretation or be deemed to constitute a part hereof.

                                       13
<PAGE>

     (c)  SEVERABILITY.  In the  event  that  any one or more of the  provisions
contained in this Agreement or in any other instrument referred to herein shall,
for  any  reason,  be  held  to  be  invalid,  illegal  or  unenforceable,  such
invalidity, illegality or unenforceability shall not affect any other provisions
of this Agreement.

     (d) BENEFITS OF AGREEMENT. All covenants and agreements contained herein by
or on behalf of any of the  parties  hereto  shall  bind and  inure  solely  and
exclusively to the benefit of the respective successors and permitted assigns of
the parties hereto.  Except as expressly  permitted hereby,  each party's rights
and  obligations  under this  Agreement  shall not be subject to  assignment  or
delegation  by any party hereto,  and any attempted  assignment or delegation in
violation hereof shall be null and void.

     (e)  ENTIRE  AGREEMENT;  MODIFICATION.  This  Agreement  and  the  Purchase
Agreement  constitute  the entire  agreement  of the parties with respect to the
subject matter hereof. This Agreement may not be modified or amended except by a
writing  signed by Savvis,  Bridge and Investors  holding at least a majority of
the shares of Restricted Stock then outstanding.  Any waiver of any provision of
this Agreement must be in a writing signed by the party against whom enforcement
of such waiver is sought.

     (f)  NOTICES.  Any notice or other  communications  required  or  permitted
hereunder shall be deemed to be sufficient if contained in a written  instrument
delivered in person or duly sent by national overnight courier service, by first
class certified mail, postage prepaid,  or by facsimile (followed by delivery by
overnight  courier)  addressed to such party at the address or facsimile  number
set forth below:

          (i) if to  Savvis,  WCAS  VIII  or  Bridge,  to it at the  address  or
     facsimile number set forth for such party on the signature page hereto: and

          (ii) if to any subsequent  Investor,  to such Investor at such address
     or facsimile  number as may have been furnished to the other parties hereto
     in writing by such holder;

or, in any case,  at such other  address or facsimile  number as shall have been
furnished  in  writing  by such  party to the  other  parties  hereto.  All such
notices,  requests,  consents and other  communications  shall be deemed to have
been  received (1) in the case of personal or courier  delivery,  on the date of
such delivery,  (2) in the case of mailing,  on the fifth business day following
the date of such mailing and (3) in the case of facsimile, when received.

     (g)  COUNTERPARTS.  This  Agreement  may  be  executed  in  any  number  of
counterparts, and each such counterpart hereof shall be deemed to be an original
instrument,  but  all  such  counterparts  together  shall  constitute  but  one
agreement.

     (h) CHANGES IN COMMON  STOCK OF SAVVIS.  If, and as often as, there are any
changes in the common  stock of Savvis by way of stock  split,  stock  dividend,
combination or

                                       14
<PAGE>

reclassification,   or  through   merger,   consolidation,   reorganization   or
recapitalization, or by any other means, appropriate adjustment shall be made in
the  provisions  hereof as may be  required  so that the rights  and  privileges
granted  hereby  shall  continue  with  respect  to the  Restricted  Stock as so
changed.

     (i) SPECIFIC PERFORMANCE. Each party hereto agrees that a remedy at law for
any  breach  or  threatened  breach  by such  party of this  Agreement  would be
inadequate and therefore agrees that any other party hereto shall be entitled to
specific performance of this Agreement in addition to any other available rights
and remedies in case of any such breach or threatened breach.

     (j)  GOVERNING  LAW. THIS  AGREEMENT  SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE  WITH  THE LAWS OF THE  STATE  OF NEW  YORK,  WITHOUT  REGARD  TO THE
CONFLICTS OF LAWS PROVISIONS THEREOF.

     IN  WITNESS  WHEREOF,  each of the  parties  hereto has duly  executed  and
delivered this Agreement as of the day and year first above written.
