                                 PURCHASE & SALE

                  2.1 Purchase and Sale of Purchased Assets;  Effective Time. On
and subject to the terms and  conditions  of this  Agreement,  the Buyer  hereby
purchases  from Seller (or shall cause the Buyer  Subsidiaries  to purchase from
the  appropriate  Seller  Subsidiaries),  and Seller  hereby  sells,  transfers,
conveys,  and delivers to the Buyer (or shall cause the Seller  Subsidiaries  to
sell, transfer,  convey and deliver to the appropriate Buyer Subsidiaries),  all
of the  Purchased  Assets at the  Closing  for the  consideration  specified  in
Section 2.3 hereof.  The Closing  shall be effective as of the close of business
on  _____________________________,  2000 ("Effective Time"); provided,  however,
that the  "Effective  Time" with respect to any Call Assets shall be as provided
in the respective Call Asset Transfer Agreement.

                  2.2 Assumption of Liabilities.

                  (a) On and  subject  to  the  terms  and  conditions  of  this
Agreement,  the Buyer hereby assumes and becomes responsible for (or shall cause
the Buyer  Subsidiaries to assume and become responsible for) all of the Assumed
Liabilities.

                  (b)  To  the  extent   that   Seller  or  any  of  the  Seller
Subsidiaries  makes  payment on any Assumed  Liabilities  which are comprised of
undisputed  liabilities  for payment of services  received  under the Contracts,
then  Buyer or a Buyer  Subsidiary  shall  reimburse  Seller  for  such  payment
promptly upon receipt of an appropriate  invoice from Seller.  Likewise,  to the
extent that Buyer or any of the Buyer Subsidiaries makes payment on any Retained
Liabilities  which are comprised of undisputed  liabilities  under the Contracts
for payment of services  received under the  Contracts,  then Seller or a Seller
Subsidiary  shall reimburse  Buyer for such payment  promptly upon receipt of an
appropriate invoice from Buyer.

                  2.3  Purchase  Price.  The Buyer agrees to pay to the Seller $
________, which shall be an amount equal to $150,000,000 less the net book value
of all the Call Assets and less the net present  value of the sublease  payments
to be made by Buyer related to the Leased Assets,  both of which amounts will be
determined by the parties at Closing (the "Purchase Price").  The Purchase Price
allocable to the Interest shall be paid partially with cash and partially with a
promissory  note  (the  "Note")  substantially  in the form  attached  hereto as
Exhibit I. The cash  portion of the  Purchase  Price is intended to be paid from
the net proceeds of the initial  public  offering by Buyer of its shares,  after
payment of all costs and expenses of such offering  including  fees and expenses
of legal  counsel,  investment  bankers,  accountants  and  other  professionals
directly engaged in connection with such public offering,  which public offering
is being made simultaneously with the Closing ("Public Offering Proceeds").  The
cash  portion  of the  Purchase  Price  shall be equal to an  amount  determined
according to the following formula:  One Hundred Million Dollars  ($100,000,000)
of the first Three Hundred  Million  Dollars  ($300,000,000)  of Public Offering
Proceeds and 50% of the remaining  Public  Offering  Proceeds in excess of Three
Hundred Million ($300,000,000),  up to the full payment of the Purchase Price in
cash.  The  principal  amount of the Note shall be the Purchase  Price less this
cash payment.  The Purchase Price allocable to the International  Network Assets
shall be allocated first from this cash amount.

                                       7
<PAGE>

The cash portion of the Purchase  Price shall be paid by the legal  entities set
forth on Schedule 2.3, or as otherwise agreed by the parties.

                  2.4  The  Closing.   The   consummation  of  the  transactions
contemplated by this Agreement (the  "Closing")  shall take place at the offices
of Bryan Cave LLP, 245 Park Avenue, New York, New York, commencing at 10:00 a.m.

                  2.5  Deliveries  at the  Closing.  The Parties  shall make the

                  (a) The  Seller  shall  execute  and  deliver to Buyer and the
Buyer shall cause Savvis Communications  Corporation, a Missouri corporation and

form of Exhibit A attached hereto,  (ii) the  Administrative  Services Agreement
substantially  in the form of Exhibit B  attached  hereto,  (iii) the  Technical
Services  Agreement  substantially  in the form of Exhibit C attached hereto and
(iv) the Bill of Sale  substantially  in the form of Exhibit D  attached  hereto
(collectively,  the agreements  listed in (a)(i)  through  (a)(iv) are sometimes
referred to herein as the "Global Operative Agreements").

                  (b) The Seller shall cause the appropriate Seller Subsidiaries
to execute and deliver, and Buyer shall cause the appropriate Buyer Subsidiaries
to execute and deliver each of the following agreements: (i) the Local Contracts
of Assignment  substantially in the form of Exhibit E attached hereto,  (ii) the
Local Asset Transfer Agreements  substantially in the form of Exhibit F attached
hereto, (iii) the Local Network Services Agreements substantially in the form of
Exhibit  G  attached  hereto  ("Local  Network  Services  Agreement"),  (iv) the
Equipment  Collocation  Permits  substantially in the form of Exhibit H attached
hereto, (v) the Local  Administrative  Services Agreements attached as Exhibit A
to the Administrative Services Agreement,  which is Exhibit B to this Agreement,
(vi) the sublease for the Leased Assets (the  "Sublease")  substantially  in the
form of Exhibit K attached hereto,  (vii) the Japanese Stock Purchase  Agreement
substantially in the form of Exhibit L attached hereto,  and (viii) the Telerate
Network Services Agreement substantially in the form of Exhibit B to the Network
Services  Agreement,  which is Exhibit A to this  Agreement  (collectively,  the
agreements listed in (b)(i) through  (b)(viii) are sometimes  referred to herein
as the "Local Operative Agreements").

                  (c) Seller and the Seller Subsidiaries shall have delivered to
the Buyer satisfactory evidence of consent of Goldman Sachs and the participants
in Seller's  lenders group,  consent to sublease of the Leased Assets,  and such
other  consents to  assignment  of the  Contracts  (as  described in Section 5.1
hereof)  and  attainment  of  governmental  approvals  as Seller  and the Seller
Subsidiaries shall have received as of the date hereof. To the extent Seller and
the Seller  Subsidiaries  shall not have received such consents or  governmental
approvals,  the rights and obligations of the parties with respect thereto shall
be governed by Section 5.1 hereof.

<PAGE>

                  (d) The Buyer will deliver to the Seller,  or Buyer will cause
the Buyer Subsidiaries to deliver to the Seller Subsidiaries, the Purchase Price
as specified in Section 2.3 above.

                  2.6      Purchase Price Allocation and Adjustment.

                  (a) Subject to adjustment as provided in Section  2.6(b),  the
Purchase  Price shall be allocated  among the Purchased  Assets as follows:  The
Purchase Price allocable to the  International  Network Assets shall be equal to
the sum of the agreed upon value of such assets,  as set forth on Schedule  1.10
("Original Asset Value").  The Purchase Price allocable to the Interest shall be
equal to the difference  between the Purchase Price and the Original Value.  The
Parties believe that the allocations in this Section 2.6(a) reflect that most of
the fair value of the  Purchased  Assets is  contained  in the assets of the LLC
because of the positive cash flows generated by the US Network Assets.

                  (b) Within fifteen days after the Closing, Seller shall update
Schedule 1.10 and Schedule 1.17 attached hereto to include all US Network Assets
and all International Network Assets owned by Seller and the Seller Subsidiaries
as of  the  Effective  Time.  If  the  sum  of  the  agreed  upon  value  of the
International  Network Assets shown on such revised  Schedule 1.10 (the "Revised
Asset Value") exceeds the Original Asset Value,  then the amount of the Purchase
Price allocable to the  International  Network Assets pursuant to Section 2.6(a)
above shall be  increased,  dollar for dollar,  by such excess and the amount of
the Purchase Price  allocable to the Interest shall be decreased by such excess.
Likewise, if the Revised Asset Value is less than the Original Asset Value, then
the amount of the Purchase Price allocable to the  International  Network Assets
pursuant to Section 2.6(a) above shall be decreased,  dollar for dollar, by such
amount and the amount of the Purchase  Price  allocable to the Interest shall be
increased by such amount.  In either event,  Seller shall  redistribute the cash
portion of the Purchase  Price paid by the Buyer  hereunder such that the Seller
Subsidiaries  are  compensated  for the  sale of  International  Network  Assets
entirely in cash. In the event  sufficient cash is not available in the Purchase
Price for this  purpose,  then the deficit  shall be funded by means of an early
prepayment under the Note.

                    REPRESENTATIONS AND WARRANTIES OF SELLER

good title to, or a valid leasehold interest in, the Purchased Assets and the US
Network Assets,  free and clear of all  Impermissible  Security  Interests,  and
there  exists no  restriction  on the  transfer  of such  property,  other  than

consummate the transactions contemplated by this Agreement, the Global Operative

of any party thereto or the creation of any Impermissible Security Interest upon
any US Network Assets or International Network Assets.

               ADDITIONAL AGREEMENTS AND COVENANTS OF THE PARTIES

                  5.1 Notices and Consents.  Except as set forth on Schedule 5.1
attached  hereto,  the  Seller  has given and  obtained  (or  caused  the Seller
Subsidiaries  to give or  obtain)  all  third-party  notices  and  consents  and
governmental  approvals necessary to effect the purchase of the Purchased Assets
and the assignment,  to the extent a replacement contract has not been executed,
of the Contracts and the assumption of the Assumed Liabilities  hereunder.  With
respect to any third party notices or consents or  governmental  approvals  that
have not been given or  obtained as of the date  hereof,  Seller  covenants  and
agrees to use its reasonable best efforts to give or obtain (or cause the Seller
Subsidiaries  to give or obtain) the same.  The Buyer agrees to fully  cooperate
with (and cause the Buyer  Subsidiaries  to fully cooperate with) the Seller and
the Seller Subsidiaries in such efforts. Until such time as Seller or the Seller
Subsidiaries   shall  have  obtained  all  necessary  third  party  consents  to
assignment  by  Buyer  or the  Buyer  Subsidiaries  of  the  Contracts  and  the
assumption by the Buyer or the Buyer  Subsidiaries  of the Assumed  Liabilities,
Seller shall  continue (or shall cause the Seller  Subsidiaries  to continue) to
discharge and perform when due all obligations  associated therewith,  and Buyer
shall reimburse Seller for any expenses directly attributable thereto.

                  5.2  Call   Right.   Seller,   for   itself   and  the  Seller
Subsidiaries,  hereby  grants to Buyer and the Buyer  Subsidiaries  the right to
purchase (the "Call Right") the following assets ("Call Assets"):

                  (a) in each of the  jurisdictions set forth on Schedule 5.2(a)
hereof and such other  jurisdictions as Buyer and Seller may, from time to time,
mutually agree (the "Call Jurisdictions"), all of the IP Network assets owned by
the Seller and/or the Seller  Subsidiaries in each Call Jurisdiction,  including
those assets set forth in Schedule  5.2(a),  subject to additions  and deletions
subsequent to the Closing  permitted under the terms of this Agreement,  and all
contract   rights   associated   therewith;   provided,   for  the   purpose  of
clarification,  that  telecommunications  circuits to  destinations  in any Call
Jurisdiction,  but originating  outside of such Call Jurisdiction,  shall not be
Call Assets and instead  shall be included in the  Acquired  Network  Facilities
transferred hereunder at the initial Closing; and

                  (b)  all  the  rights  and  obligations  with  respect  to the
satellite  communications  agreements and all rights and obligations in specific
countries  with respect  thereto,  as described

                                       13
<PAGE>

in Schedule 5.2(b), subject to additions and deletions subsequent to the Closing
permitted under the terms of this Agreement, (the "Satellite Rights").

Unless  earlier  terminated  pursuant to Section 5.6  hereunder,  the Call Right
granted  hereunder  shall  expire on the tenth  anniversary  of the date  hereof
("Expiration Date"); provided, however, that if the term of the Network Services
Agreement is extended beyond the Expiration Date, then the Expiration Date shall
be the date upon which the  Network  Services  Agreement,  attached as Exhibit A
hereto,  is  terminated.  Upon  the  exercise  of the  Call  Right  in any  Call
Jurisdiction  or with respect to the  Satellite  Rights,  Buyer shall assume all
liabilities and obligations of the Seller and/or the Seller Subsidiaries related
to the respective  Call Assets to the extent that such  liabilities  arise on or
after the date of exercise.

                  5.3  Exercise  of Call Right.  Buyer shall use its  reasonable
best efforts, from and after the Closing, to secure the consents,  licenses, and
other  authorizations,  whether  from  governments  or private  parties,  and to
establish such foreign legal presence and to fulfill such other  conditions,  as
are  necessary in order to permit  Buyer to acquire the Call  Assets;  provided,
however,  that this obligation shall not require that Buyer permit third parties
to own a portion of any  subsidiaries of Buyer unless Buyer otherwise  agrees to
such ownership.  Prior to the receipt of all such material  consents,  licenses,
and  authorizations  and the  establishment of any necessary  foreign  presence,
Buyer shall not be  obligated  to exercise the Call Right with respect to any or
all of the Call Jurisdictions or with respect to the Satellite Rights, nor shall
Buyer be obligated to exercise  all the Call Rights at one time;  rather,  Buyer
may  exercise the Call Right in each Call  Jurisdiction  and with respect to the
Satellite  Rights  separately,  from time to time,  and at any time prior to the
Expiration Date subject to the immediately following provision. Upon the receipt
of all material  consents,  licenses and authorizations and the establishment of
any necessary  foreign presence in any Call  Jurisdiction or with respect to all
the Satellite Rights connected with a particular third-party satellite contract,
Buyer shall be obligated to proceed  expeditiously with the exercise of the Call
Right with respect to such Call Jurisdiction or Satellite  Rights.  The exercise
price of the Call Right,  other than with respect to Satellite  Rights,  in each
Call  Jurisdiction  shall be $1.00 plus the net book value of the Call Assets in
the applicable  Call  Jurisdiction(s)  on the date of exercise of the Call Right
for such Call  Jurisdiction.  The exercise of the Call Right with respect to the
Satellite  Rights shall only be permitted if made with respect to all  Satellite
Rights under a  particular  global  satellite  contract as set forth on Schedule
5.2(b),  and  the  exercise  price  shall  be $1  plus  the  assumption  of  all
obligations  of Seller with respect to such  contract.  The Call Assets shall be
transferred  via a Call  Asset  Transfer  Agreement  in  substantially  the form
attached as Exhibit J hereto. Upon the exercise of a Call Right, a Local Network
Services  Agreement for the respective Call  Jurisdiction  substantially  in the
form of Exhibit G attached  hereto will be executed  by the  appropriate  Seller
Subsidiaries and Buyer Subsidiaries.

                  5.4 Seller's Obligation with Respect to Call Assets. Until the
earliest  of (a) the  Expiration  Date,  (b) the date upon which no Call  Assets
remain subject to the Call Right,  or (c) the Call Right is terminated  pursuant
to Section 5.6, and subject at all times to the rights and obligations set forth
in the Network  Services  Agreement  executed between the parties as of the same
date as the date of this Agreement:

                                       14
<PAGE>

                  (a) Seller  shall  maintain  and  operate (or cause the Seller
Subsidiaries  to maintain and operate) the Call Assets in the same manner and to
the same extent as Seller and the Seller Subsidiaries,  as the case may be, have
maintained  such assets to date.  Seller  shall take (and shall cause the Seller
Subsidiaries  to take) any and all actions  reasonably  necessary to fulfill its
obligations hereunder;

                  (b)  Seller   shall  not  (nor  shall  it  permit  the  Seller
Subsidiaries to) dispose of, encumber or otherwise  transfer any interest in, or
amend,  waive or modify any provision of or terminate any Contract  relating to,
the Call Assets  without the prior written  consent of Buyer which consent shall
not be unreasonably withheld; provided,  "unreasonable" shall be determined from
the perspective of Buyer and shall include all actions which may have a material
adverse effect if Buyer were to exercise the related Call Right;

                  (c)  Seller   shall   provide  (and  shall  cause  the  Seller
Subsidiaries to provide) Buyer with notice of any events that have, or may have,
a material  adverse  effect on the Call Assets or on Buyer's right or ability to
exercise the Call Right with respect to any of the Call Assets;

                  (d) If Buyer  chooses to exercise  any Call Right prior to the
receipt of all consents,  licenses and other  authorizations or establishment of
the appropriate  foreign legal  presence,  it does so with the assumption of all
risk or other liability arising from such absence of necessary consents, license
or other  authorizations  or legal  presence.  Upon  exercise of any Call Right,
Seller shall use its reasonable  best efforts to obtain any required  consent of
any other  contracting  parties to the  assignment  or novation of any agreement
pertaining to the  applicable  Call Assets,  and Buyer shall use its  reasonable
best  efforts  to assist  Seller in all such  endeavors.  Unless  and until such
consent  shall be  forthcoming  and any  relevant  agreements  shall  have  been
assigned or novated,  Buyer  shall at its own cost and expense  assume  Seller's
obligations under such agreements and Seller shall account to Buyer for all sums
received therefrom. Seller will at Buyer's request and expense give to Buyer all
assistance  in the  power  of  Seller  to  enable  Buyer to  enforce  any of the
agreements  so assigned  against  the other  contracting  party or parties  and,
without  prejudice to the  generality  of the  foregoing,  will provide all such
relevant books, documents and other information as Buyer may require in relation
thereto; and

                  (e) Buyer shall have no rights to use the Call Assets prior to
exercise of the Call Rights,  except as otherwise  consented to by Seller,  such
consent not to be unreasonably withheld.

                  5.5 Buyer's  Obligations  with  Respect to Call  Assets.  With
respect to those Call Assets in the Call Jurisdictions set forth on Schedule 5.5
("Short-Term  Call  Assets"),  Buyer and Seller  expect the exercise of the Call
Right to occur  within the  calendar  year  2000.  Regardless  if such  exercise
actually occurs in 2000,  with respect to the Short-Term  Call Assets,  Buyer or
the Buyer Subsidiaries shall reimburse the Seller or the Seller Subsidiaries for
all costs  requiring an expenditure of cash which are directly  associated  with
the use, maintenance and operation of the Short-Term Call Assets, including, but
not limited to, maintenance of leased lines.  Seller shall invoice Buyer monthly
for such  costs.  Likewise,  Seller  shall  compensate  Buyer for the use of the
Short-Term  Call Assets  pursuant to such Network  Services  Agreement

                                       15
<PAGE>

executed  between the parties as of the same date as the date of this Agreement.
Such  obligations of Buyer and Seller shall run  concurrently and shall continue
until the  Expiration  Date,  unless earlier  terminated by mutual  agreement of
Buyer and  Seller.  No similar  obligations  will exist for Buyer or Seller with
respect to the  remaining  Call Assets  prior to the exercise of the Call Rights
with respect thereto.

                  5.6 Termination of Call Right.  The Call Right shall terminate
automatically on the earlier of the Expiration Date or the date upon which Buyer
has  exercised  the Call Right in each of the Call  Jurisdictions.  Prior to the
Expiration  Date,  at any time and from  time to  time,  the Call  Right  may be
terminated with respect to any or all of the Call  Jurisdictions upon the mutual
agreement of the parties.

                  5.7 Employee  Services.  From and after the Closing until such
time as the  Employees  are  transferred  to the Buyer  pursuant to Section 5.8,
Seller shall make all of the Employees  available to Buyer on a full-time basis.
Buyer shall reimburse Seller, on a monthly basis, for all payroll costs directly
associated with such Employees.

                  5.8 Offers of Employment.

                  (a) As of December 31, 1999, Buyer has offered employment with
the Buyer to the Employees,  and Seller has released from their employment those
Employees  who  accepted  employment  with the Buyer to enable  them to commence
their employment with the Buyer.  Such Employees  commenced  employment with the
Buyer on January 1, 2000 (the "Employment Date").

                  (b) Seller shall  furnish  Buyer with all employee  data files
related to the  Employees.  The Seller makes no  representations  or  warranties
concerning such files, or the contents or sufficiency thereof.

                  5.9 Employee Benefits.

                  (a) Employees  shall  continue to participate in each Employee
Benefit  Plan  maintained  by Seller  until such time as Buyer  establishes  and
maintains a substantially  similar Employee  Benefit Plan;  provided that, as of
the  Employment  Date, an Employee  shall cease to be eligible to participate in
the Bridge Information Systems,  Inc. 401(k) Salary Savings Plan ("Bridge Plan")
and shall be eligible to  participate  in the Savvis  Communications  Co. 401(k)
Plan ("Savvis Plan"), in accordance with the terms of Section 5.9(b) and subject
to the terms of the  Savvis  Plan.  During  the  period in which  Employees  are
participating in Seller's  Employee Benefit Plans,  Buyer shall reimburse Seller
for any employer-paid amounts under such Employee Benefit Plans.

                  (b) As soon as practicable  after the Employment Date,  Seller
shall cause to be transferred from the Bridge Plan to the Savvis Plan all Bridge
Plan assets  representing  account  balances of Employees under the Bridge Plan.
Buyer and Seller  shall take all such  actions as are  necessary  to ensure that
such transfer complies with all relevant  provisions of Section 411(d)(6) of the
Code and the regulations  thereunder.  Buyer shall amend the Savvis Plan, to the
extent

                                       16
<PAGE>

necessary, to provide that each Employee is credited, for all purposes under the
Savvis Plan and subject to the other  provisions of such plan,  with all service
completed prior to the Employment Date with Seller.

                  (c) Buyer shall  assume the  obligations  in  connection  with
accrued but unused  vacation  and shall be  responsible  for vacation pay at and
after the Employment Date with respect to service (whether prior to or after the
Employment Date) of all Employees. Buyer shall afford Employees credit for their
period of  employment  with  Seller for  purposes of  determining  the amount of
vacation  to which the  Employees  are  entitled  each year and for  purposes of
determining all other seniority based benefits.

                  (d)  Buyer  and   Seller   acknowledge   and  agree  that  the
transactions  contemplated  by this Agreement shall not constitute a termination
of employment of any Employee.

                  (e)  No  provision  of  this  Agreement,   including   without
limitation this Section 5.9, shall create any third-party  beneficiary rights in
any person or organization,  including  without  limitation  employees or former
employees (including any beneficiary or dependent thereof) of Seller,  unions or
other  representatives  of such  employees  or former  employees,  or  trustees,
administrators, participants, or beneficiaries of any Employee Benefit Plan, and
no provision of this  Agreement,  including  this Section 5.9, shall create such
third-party  beneficiary rights in any such person or organization in respect of
any benefits that may be provided,  directly or  indirectly,  under any Employee
Benefit Plan.

                  (f) Seller and Buyer  shall  cooperate  as may  reasonably  be
required  with respect to each of the filings,  calculations,  and other actions
necessary  to effect the  transactions  contemplated  by this Section 5.9 and in
obtaining any government approvals as may be required hereunder.

                  5.10  Access  to  Employee  Information.  From and  after  the
Closing, the parties hereto will cooperate with each other in the administration
of any applicable  Employee Benefit Plans and programs.  To the extent permitted
by law, at the  Employment  Date or within a  reasonable  time  thereafter,  the
Seller will provide the Buyer the  necessary  employee  data or copies  thereof,
including  personnel  and benefit  information,  maintained  with respect to the
Employees  by the Seller or by its  independent  contractors,  such as insurance
companies and actuaries.

                  5.11 WARN Act  Indemnification.  The Buyer agrees to indemnify
the Seller and its directors,  officers, employees,  consultants and agents for,
and to hold the Seller and its directors,  officers, employees,  consultants and
agents  harmless from and against,  any and all losses arising or resulting,  or
alleged to arise or result from the  notification  or other  requirements of the
WARN Act.

                  5.12  Workers'   Compensation   Claims.  The  Seller  will  be
responsible  for any workers'  compensation  claims by any Employee for injuries
incurred prior to such Employee's Employment Date. The Buyer will be responsible
for any workers' compensation claims for injuries incurred by any Employee on or
after such Employee's Employment Date.

                                       17
<PAGE>

                  5.13 Employee Benefit Plans.  Except as expressly  provided in
this Article V, the Buyer will not adopt, assume or otherwise become responsible
for, either primarily or as a successor  employer,  any assets or liabilities of
any Employee  Benefit Plans,  arrangements,  commitments  or policies  currently
provided by the Seller or by any member of its controlled group of corporations.
In addition,  the Buyer will not assume Seller's  obligations under Code Section
4980B and ERISA Section 606 relating to  individuals  who are neither  Employees
nor  dependents  of  Employees.   Buyer  shall  be  responsible  for  satisfying
obligations   under  ERISA   Section  606  and  Code  Section  4980  to  provide
continuation  coverage to or with respect to any  Employees  with respect to any
"qualifying event" which occurs on or following the Employment Date.

                  5.14 Further Assurances.  From and after Closing,  the parties
shall  do such  acts  and  execute  such  documents  and  instruments  as may be
reasonably required to make effective the transactions  contemplated  hereby. In
the  event  that  consents,   approvals,  other  authorizations  or  other  acts
contemplated  by this Agreement have not been fully effected as of Closing,  the
parties will continue after Closing, without further consideration, to use their
reasonable best efforts to carry out such transactions;  provided,  however,  in
the event that  certain  approvals,  consents or other  necessary  documentation
cannot be secured,  then the party  having  legal  responsibility,  ownership or
control shall act on behalf of the other party,  without further  consideration,
to  effect  the  essential   intention  of  the  parties  with  respect  to  the
transactions contemplated by this Agreement.

                                   ARTICLE VI

                  6.1   Survival  of   Representations   and   Warranties.   The
representations  and  warranties of the Seller  contained in Article III of this
Agreement  and of the Buyer  contained  in  Article IV of this  Agreement  shall

                  6.2 Indemnification Provisions for Benefit of the Buyer.

                  (a)  Subject to the  limitations  set forth in Section  6.2(c)

representations, warranties, and covenants contained in this Agreement, provided
that the Buyer makes a written claim for indemnification against the Seller with
respect to its  representations  and warranties  within the survival  period set

Buyer Subsidiaries from and against the entirety of any Adverse Consequences the

liability, or otherwise by operation of law).

                  (c) Notwithstanding anything to the contrary, (i) Seller shall

(or group of  related  claims)  unless  such  claim or group of  related  claims

                  (d) Without  limitation,  Seller agrees to indemnify the Buyer
and the  Buyer  Subsidiaries  from  and  against  the  entirety  of any  Adverse
Consequences  the  Buyer  and  the  Buyer   Subsidiaries   shall  suffer  caused

or any Buyer Subsidiaries for transmission over the IP Network.

                  6.3 Indemnification Provisions for Benefit of Seller.

                  (a) In the event the  Buyer or any Buyer  Subsidiary  breaches
any  of  its  representations,  warranties,  and  covenants  contained  in  this
Agreement,  provided that the Seller makes a written  claim for  indemnification
against the Buyer within the survival period with respect to its representations
and  warranties,  then the Buyer agrees to  indemnify  the Seller and the Seller
Subsidiaries  from and against the  entirety  of any  Adverse  Consequences  the
Seller and the Seller  Subsidiaries  shall suffer  through and after the date of
the claim for indemnification (but excluding any Adverse Consequences the Seller

survival period) caused proximately by the breach.

                  (b) Buyer  agrees  to  indemnify  the  Seller  and the  Seller

                  6.4 Matters Involving Third Parties.

                  (a)  If  any  third   party   shall   notify  any  party  (the
"Indemnified  Party") with respect to any matter (a "Third Party  Claim")  which
may give rise to a claim  for  indemnification  against  the  other  party  (the
"Indemnifying  Party") under this Article VI, then the  Indemnified  Party shall
promptly (and in any event, if the matter concerns a legal proceeding, within 15
business days after receiving  notice of the Third Party Claim, and with respect
to any other  matter,  within 30 business  days) notify the  Indemnifying  Party
thereof in writing.

                                       19
<PAGE>

                  (b) The Indemnifying  Party will have the right at any time to
assume and thereafter  conduct the defense of the Third Party Claim with counsel
of its  choice  reasonably  satisfactory  to the  Indemnified  Party;  provided,
however, that

                           (i) if the Third Party  Claim falls  within the scope
         of  the   indemnification   set  forth  in  Section  6.2(d),  then  the
         Indemnified  Party  shall  have the  right to  refuse  to  accept  such
         assumption of defense by Indemnifying  Party unless and until such time
         as the Indemnifying  Party shall provide to the Indemnified  Party such
         assurances  of  payment  and   performance   of  such   indemnification
         obligation  as  shall be  reasonably  satisfactory  to the  Indemnified
         Party; and

                           (ii) the  Indemnifying  Party will not consent to the
         entry of any judgment or enter into any settlement  with respect to the
         Third Party Claim without the prior written  consent of the Indemnified
         Party (not to be withheld unreasonably) unless the judgment or proposed
         settlement  involves  only the  payment of money  damages  and does not
         impose an injunction  or other  equitable  relief upon the  Indemnified
         Party.

                  (c)  Unless  and  until the  Indemnifying  Party  assumes  the
defense of the Third Party Claim as provided in Section  6.4(b) above,  however,
the Indemnified  Party may defend against the Third Party Claim in any manner it
reasonably may deem appropriate,  including, without limitation,  consent to the
entry of any  judgment or enter into any  settlement  with  respect to the Third
Party Claim.

                  6.5 Call  Right  Remedies.  The  parties  agree  that the Call
Assets  and the Call  Right  are  unique  interests  and  that,  in the event of
Seller's  breach of its  obligations  with respect to the Call Assets,  monetary
damages will not fully compensate Buyer. Therefore, the parties agree that Buyer
shall  have the  remedies  which  are  available  to it for  Seller's  breach or
violation  of any of the  provisions  of this  Agreement  relating  to the  Call
Assets,  including,  but not limited to, the  equitable  remedies  for  specific
performance and injunctive relief.

                  6.6 Exclusive Remedy. The Buyer and the Seller acknowledge and
agree that,  subject to the other  remedies  granted to the Buyer in Section 6.5
hereof, the foregoing indemnification provisions in this Article VI shall be the
exclusive  remedy of the Buyer and the Seller with  respect to the  transactions
contemplated by this Agreement.

                                   ARTICLE VII

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;
provided,  however, Seller and Seller Subsidiaries shall have the right to grant
a security  interest or mortgage  with  respect to, or make any  assignment  for
security purposes or pledge of, Seller's and Seller  Subsidiaries'  rights under
this  Agreement  and  any of the  Global  Operative  Agreements  and  the  Local
Operative  Agreements,  to the extent  required by the senior  lending  group of

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.

                  (c) The  arbitration  shall be conducted by three  arbitrators
(the "Arbitrators"),  one of whom shall be selected by Seller, one by Buyer, 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.

                  (d)  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  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.

                  (e) 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.

                  (f) 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 7.7.

                  (g) 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.

                  7.8 Amendments  and Waivers.  No amendment of any provision of
this Agreement  shall be valid unless the same shall be in writing and signed by
the  Buyer   and  the   Seller.   No  waiver  by  any  party  of  any   default,
misrepresentation,   or  breach  of  warranty  or  covenant  hereunder,  whether
intentional  or not,  shall be  deemed  to  extend  to any  prior or  subsequent
default,  misrepresentation,  or breach of  warranty or  covenant  hereunder  or
affect in any way any rights  arising by virtue of any prior or subsequent  such
occurrence.

                  7.9 Severability. Any term or provision of this Agreement that
is invalid or  unenforceable  in any  situation  in any  jurisdiction  shall not
affect the validity or  enforceability  of the  remaining  terms and  provisions
hereof or the validity or  enforceability  of the offending term or provision in
any other situation or in any other jurisdiction.

                  7.10 Expenses.  Each of the Seller and the Buyer will bear its
own  costs  and  expenses  (including  legal  fees  and  expenses)  incurred  in
connection with this Agreement and the transactions contemplated hereby.

                  7.11 Construction. Any reference to any federal, state, local,
or  foreign  statute  or law  shall be  deemed  also to refer to all  rules  and
regulations promulgated thereunder,  unless the context requires otherwise.  The
word "including" shall mean including without limitation.

                  7.12 Incorporation of Exhibits and Schedules. The Exhibits and
Schedules  identified in this Agreement are incorporated herein by reference and
made a part hereof.

                  7.13  Bulk  Transfer  Laws.  The Buyer  acknowledges  that the
Seller does not believe that the  provisions  of any bulk  transfer  laws of any
jurisdiction  are  applicable to this  transaction  and will not comply with any
such laws in connection with the transactions contemplated by this Agreement.

2.       THE SERVICES

         2.2.    From time to time during the term of this Agreement, SAVVIS may
                 terminate  one  or  more  Services  being  provided  by  Bridge

<PAGE>

         2.4.    In addition to the Services  provided under this Agreement,  it
                 is expected  that  additional  administrative  services will be
                 provided  under  the  separate  Local  Administrative  Services
                 Agreements  between  certain  SAVVIS  Subsidiaries  and certain
                 Bridge  Subsidiaries,  substantially  in the form of  Exhibit A
                 attached  hereto.  Services  provided  under  each  such  Local
                 Administrative  Services Agreement shall be billed locally,  in
                 local currency.

3.       RATES AND CHARGES

         SAVVIS shall pay Bridge for the Services at rates to be mutually agreed
         by the parties;  provided,  however,  that such rates shall be based on
         the cost to Bridge of providing  the Services to SAVVIS,  except to the
         extent contrary to local law.

4.       INVOICES

         4.1.    The amounts due to Bridge from SAVVIS for the Services shall be
                 billed  monthly  in  arrears.  All  items on  invoices  not the
                 subject  of a bona fide  dispute  shall be payable by SAVVIS in
                 United States  currency within 30 days from the date of receipt
                 of the  invoice.  All  amounts  not in dispute  are  subject to
                 interest charges of 1-1/2 percent that will accrue daily on all
                 amounts  not paid  within 30 days of the date of receipt of the
                 invoice.

         4.2.    SAVVIS shall pay any sales,  use, value added,  federal excise,
                 utility,  gross  receipts,  state  and  local  surcharges,  and
                 similar  taxes,  charges  or levies  lawfully  levied by a duly
                 constituted  taxing 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. As part of the Services, Bridge will administer the
                 payment of SAVVIS' payroll taxes.  SAVVIS will reimburse Bridge
                 for such payroll taxes as invoiced  under this  Agreement.  All
                 other  taxes,  charges  or  levies  related  to  the  Services,
                 including any income, franchise, privilege, or occupation taxes
                 of  Bridge  shall  be  paid  by  Bridge.  Except  as  otherwise
                 specifically  addressed in this  Agreement  or Addenda  hereto,
                 each party shall pay its own 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
                 SAVVIS'  account.  Any amount to which  Bridge is entitled as a
                 result of the  resolution  of a billing  dispute  shall be paid
                 promptly to Bridge.

5.       TERM AND EXTENSIONS

         5.1.    The  initial  term of this  Agreement  shall  be  three  years,
                 commencing on the Effective  Date,  and shall  continue in full
                 force  and  effect   unless   terminated  in  accord  with  the
                 provisions hereof.

         5.2.    The  term of this  Agreement  shall  automatically  extend  for
                 consecutive  one-year  periods  unless  either  party gives the
                 other party advance  written  notice of such party's intent not
                 to extend not less than 60 days before the scheduled expiration
                 of the then current term.

6.       TERMINATION BY BRIDGE

         Bridge shall have the right to terminate this Agreement if:

                  (a)      SAVVIS has failed to pay any invoice  that is not the
                           subject of a bona fide dispute  within 30 days of the
                           date on which  such  payment  is due and  Bridge  has
                           provided SAVVIS with written notice thereof, provided
                           that  SAVVIS  shall  have 10 days  from  the  time it
                           receives  such notice from  Bridge of  nonpayment  to

                         agents  and  representatives   insurance  as  shall  be
                         mutually agreed upon by the parties and set forth in an
                         Addendum  to this  Agreement  in the  manner  set forth
                         herein.

                 8.2.2.  Bridge shall furnish to SAVVIS,  upon written  request,

               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.

         9.2.  Nothing  contained  in this Section  shall limit  either  party's

               from the date of its  expiration or  termination  (including  all

               confidence  all  Confidential

                                       31
<PAGE>

                Information.  Neither party shall, without prior written consent
                of  the  other  party,   use  the  other  party's   Confidential
                Information  for any purpose other than for the  performance  of
                its duties and  obligations,  and the  exercise  of its  rights,
                under this Agreement.  Each party shall use, and shall cause all
                authorized   recipients  of  the  other   party's   Confidential
                Information to use, the same degree of care to protect the other
                party's  Confidential  Information as it uses to protect its own
                Confidential  Information,  but in any  event  not  less  than a
                reasonable degree of care.

         11.2.  Notwithstanding  Section  12.1,  either  party may  disclose the
                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.

         11.3.  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.

         11.4.  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.

         11.5.  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.

         11.6.  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 party's consent to
                such disclosure,  use its reasonable best efforts to resist, and
                to assist the other party in resisting, such disclosure. A party
                providing another

                                       32
<PAGE>

                party's   Confidential   Information   to  a  court   or   other
                governmental  authority shall use its reasonable 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.

         11.7.  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 such due diligence review.

12.      INDEMNIFICATIONS

         12.1.  SAVVIS shall indemnify,  defend,  and hold Bridge (including any
                of  its  directors,  officers,  employees,  agents  or  assigns)
                harmless  from any  claims,  actions or suits to the extent that
                such claim or action arises from Bridge's provision to SAVVIS of
                the Services  and to the extent that such claim,  action or suit
                does  not  arise  from  the  gross   negligence  or  intentional
                misconduct of Bridge.  SAVVIS may settle, or otherwise manage at
                its own cost and  expense  any such  claims,  actions  or suits.
                Bridge  shall  notify  SAVVIS  promptly  in  writing of any such
                claim,  action  or suit and  shall  cooperate  with  SAVVIS in a
                reasonable way to facilitate the settlement or defense thereof.

         12.2.  Bridge shall indemnify,  defend,  and hold SAVVIS (including any
                of  its  directors,  officers,  employees,  agents  or  assigns)
                harmless  from any  claims,  actions or suits to the extent that
                such claim or action  arises from Bridge's  gross  negligence or
                intentional  misconduct  in  the  provision  to  SAVVIS  of  the
                Services, unless such claim, action or suit also arises from the
                gross negligence or intentional misconduct of SAVVIS. Bridge may
                settle, or otherwise manage at its own cost and expense any such
                claims, actions or suits. SAVVIS shall notify Bridge promptly in
                writing of any such  claim,  action or suit and shall  cooperate
                with Bridge in a reasonable  way to facilitate the settlement or
                defense thereof.

         13.1.  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.

         13.2.  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.

         13.3.  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.

         13.4.  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.

         13.5.  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 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.

                                       34

         13.6.  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.

         13.7.  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.

         13.8.  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.

         13.9.  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.

14.      FORCE MAJEURE

         14.1.  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.

         14.2.  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 one
                or more third  parties for 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.

                                       35
<PAGE>

         14.3.    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.

15.      GENERAL PROVISIONS

         15.1.  NO THIRD-PARTY  BENEFICIARIES.  This Agreement  shall not confer

                 FORM OF LOCAL ADMINISTRATIVE SERVICES AGREEMENT

         This LOCAL  ADMINISTRATIVE  SERVICES  AGREEMENT  (the  "AGREEMENT")  is
effective as of  ______________,  2000 (the  "EFFECTIVE  DATE"),  between [local
SAVVIS entity], a company organized under the laws of [country] ("SAVVIS"),  and
[local Bridge/Telerate  entity], a company organized under the laws of [country]
("PROVIDER").

                                    RECITALS

         A. Provider is engaged in the business of collecting  and  distributing
various financial, news and other data in [country] (the "JURISDICTION").

         B. SAVVIS is engaged in the business of providing Internet backbone and
other data transport services in the Jurisdiction.

         C. SAVVIS Parent and Bridge Parent have entered into an  Administrative
Services  Agreement,  of  even  date  herewith  (the  "ADMINISTRATIVE   SERVICES
AGREEMENT")  for the provision  and receipt of similar  services on a world-wide
basis at the parent  level as are being  provided and received by the parties to
this Agreement within the Jurisdiction.

         D.  Together with this  Agreement,  the SAVVIS is entering into certain
other  agreements  with  Provider,  or Affiliates of Provider,  related to their
operations in the Jurisdiction,  including Local Transfer Agreements,  Equipment
Collocation Permits, and Local Network Services Agreements.

         NOW,  THEREFORE,  in  consideration  of the  premises,  and the  mutual
covenants  contained  herein and of other good and valuable  consideration,  the
receipt and  adequacy  of which are hereby  acknowledged,  the parties  agree as
follows:

1.       CONTRACT DOCUMENTS AND DEFINITIONS

         1.1.    This  Agreement  shall  consist  of this  Local  Administrative
                 Services   Agreement  by  and  between   SAVVIS  and  Provider,
                 including  all addenda to this  Agreement  entered  into in the
                 manner set forth herein (each an  "ADDENDUM"  and  collectively
                 the "ADDENDA").  This Agreement  shall be interpreted  wherever
                 possible to avoid conflicts between the Sections hereof and the
                 Attachments,  provided that if such a conflict shall arise, the
                 Attachments shall control.

         1.2.    Whenever it is provided  in this  Agreement  for a matter to be
                 mutually  agreed  upon  by the  parties  and  set  forth  in an
                 Addendum  to this  Agreement,  either  party may  initiate  the
                 process of  determining  such matter by  submitting  a proposed
                 outline or contents of such  Addendum to the other party.  Each
                 party shall appoint a primary  contact and a secondary  contact
                 for the completion of such  Addendum,  who shall be the contact
                 points for every issue  concerning  such Addendum and

                  who shall be informed  of the  progress  of the  project.  The
                  names of the  contacts  will be  exchanged  in  writing by the
                  parties.  Using the contacts,  the parties shall work together
                  in good faith  with such  diligence  as shall be  commercially
                  reasonable under the  circumstances to complete such Addendum,
                  provided,  however,  that neither  party shall be obligated to
                  enter  into  such an  Addendum.  Upon the  completion  of such
                  Addendum,  it shall be set  forth in a  written  document  and
                  executed  by the  parties  and  shall  become  a part  of this
                  Agreement  and shall be deemed  to be  incorporated  herein by
                  reference.

                  below shall have the  meanings  given  below,  and all defined
                  terms shall include the plural as well as the singular. Unless

                  similar words refer to this  Agreement as a whole and not to a
                  particular Section or other subdivision.  The words "included"
                  and "including" shall not be construed as terms of limitation.

                  regulations  promulgated under the Securities  Exchange Act of
                  1934, as amended.

                  the Effective Date and each subsequent anniversary thereof.

                  "BRIDGE  PARENT"  means Bridge  Information  Systems,  Inc., a

                  source (i) by Provider by virtue of its performance under this
                  Agreement  or  (ii)  by  SAVVIS  by  virtue  of its use of the
                  Services.  Such  information  shall also  include the terms of
                  this Agreement (and  negotiations and proposals from one party
                  to the other related  directly  thereto),  network designs and
                  design recommendations,  tools and programs, pricing, methods,
                  processes,  financial data, software,  research,  development,
                  strategic plans or related  information.  All such information
                  disclosed  prior to the execution of this Agreement shall also

         4.1.     The amounts due to Provider from SAVVIS for the Services shall

                  resolution of a billing dispute shall be credited  promptly to
                  SAVVIS' account. Any amount to which Provider is entitled as a

                         Provider  shall  maintain  for  itself,  its  officers,
                         employees,  agents  and  representatives  insurance  as
                         shall be  mutually  agreed  upon by the parties and set
                         forth in an  Addendum to this  Agreement  in the manner
                         set forth herein.

                  8.2.2. Provider shall furnish to SAVVIS, upon written request,

                         above,  naming  SAVVIS as an additional  insured.  Such

                         with this Section.

                  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

                  of their respective agents, subcontractors or employees.

10.      PROPRIETARY RIGHTS; LICENSE

         10.1.    Provider   hereby  grants  to  SAVVIS  a   non-exclusive   and
                  non-transferable  license to use all  programming and software
                  necessary  for  SAVVIS to use the  Services.  Such  license is
                  granted for the term of this Agreement for the sole purpose of
                  enabling SAVVIS to use the Services.

         10.2.    All title and property rights (including intellectual property
                  rights) to  Services  (including  associated  programming  and
                  software) are and shall remain with Provider. SAVVIS shall not
                  attempt  (except as permitted by  applicable  law) to examine,
                  copy, alter, reverse engineer, decompile,  disassemble, tamper
                  with  or  otherwise  misuse  such  Services,  programming  and

11.      CONFIDENTIALITY

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

         11.2.    Notwithstanding  Section  11.1,  either party may disclose the
                  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

                                       45
<PAGE>

                  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.

         11.3.    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.

         11.4.    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.

         11.5.    Provider  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.

         11.6.    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
                  party's  consent to such  disclosure,  use its reasonable 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  reasonable  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.

         11.7.    The  provisions  of  Section  11.1  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

                                       46
<PAGE>

                  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 such due diligence
                  review.

12.      INDEMNIFICATIONS

         12.1.    SAVVIS shall indemnify,  defend, and hold Provider  (including
                  any of its directors,  officers, employees, agents or assigns)
                  harmless from any claims,  actions or suits to the extent that
                  such  claim or action  arises  from  Provider's  provision  to
                  SAVVIS of the  Services  and to the  extent  that such  claim,
                  action  or suit does not arise  from the gross  negligence  or
                  intentional  misconduct  of  Provider.  SAVVIS may settle,  or
                  otherwise  manage at its own cost and expense any such claims,
                  actions or suits.  Provider  shall notify  SAVVIS  promptly in
                  writing of any such claim,  action or suit and shall cooperate
                  with SAVVIS in a reasonable  way to facilitate  the settlement
                  or defense thereof.

         12.2.    Provider shall indemnify,  defend,  and hold SAVVIS (including
                  any of its directors,  officers, employees, agents or assigns)
                  harmless from any claims,  actions or suits to the extent that
                  such claim or action arises from Provider's  gross  negligence
                  or  intentional  misconduct  in the provision to SAVVIS of the
                  Services,  unless such claim,  action or suit also arises from
                  the gross  negligence  or  intentional  misconduct  of SAVVIS.
                  Provider may settle,  or otherwise  manage at its own cost and
                  expense any such claims, actions or suits. SAVVIS shall notify
                  Provider promptly in writing of any such claim, action or suit
                  and shall  cooperate  with  Provider  in a  reasonable  way to
                  facilitate the settlement or defense thereof.

13.      DISPUTES

         13.1.    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 13.
                  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.

         13.2.    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

                                       47
<PAGE>

                  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.

         13.3.    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.

         13.4.    The arbitration  shall be conducted by three  arbitrators (the
                  "ARBITRATORS"), one of whom shall be selected by Provider, 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.

         13.5.    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
                  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.

         13.6.    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.

         13.7.    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 13.

                                       48
<PAGE>

         13.8.    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.

         13.9.    Pending the resolution of any dispute or  controversy  arising
                  under this  Agreement,  the parties shall  continue to perform
                  their respective obligations hereunder, and Provider 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.

14.      FORCE MAJEURE

         14.1.    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.

         14.2.    If  Provider  cannot  promptly  provide a  suitable  temporary
                  Provider  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
                  one or more third parties for any or all affected Services for
                  the shortest commercially available period likely to cover the
                  reasonably  expected  duration  of the  Interruption,  and may
                  suspend Provider's provision of such Services for such period.
                  Provider  shall  not  charge  SAVVIS  for  any  Services  thus
                  suspended  during the  period of  suspension.  Provider  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.

         14.3.    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 Provider other than for Services
                  received  by  SAVVIS  prior  to the  occurrence  of the  force
                  majeure condition.

15.      GENERAL PROVISIONS

         15.1.    NO THIRD-PARTY BENEFICIARIES. [This Agreement shall not confer

                  the  parties and their  respective  successors  and  permitted

                  to this Agreement whether pursuant to the Contracts (Rights of
                  Third Parties) Act, 1999 or otherwise.]

               FORM OF LOCAL CONTRACT OF ASSIGNMENT AND ASSUMPTION

                      CONTRACT OF ASSIGNMENT AND ASSUMPTION

                  This  Contract  is  entered  into  as  of  this  ____  day  of
_________,  2000 by and  between  SAVVIS  [______________],  a [private  limited
liability]  company  organized  under the laws of  [______________]  ("SAVVIS"),
[having  a  non-registered   __________   branch],   and   [______________],   a
[______________]   company   organized   under  the  laws  of   [______________]
("Assignor").

                  WHEREAS,  SAVVIS is acquiring  certain assets and  liabilities
from various  companies  affiliated  with Assignor,  such assets and liabilities
comprising  and  relating to the IP Network  that  Assignor  and its  affiliated
companies currently own and operate; and

                  WHEREAS,  Assignor  desires  to assign to  SAVVIS  and  SAVVIS
desires to assume  from  Assignor  certain  contracts  and  liabilities  as more
particularly  set forth at  Schedule  1 to this  Contract  (the  "Contracts  and
Liabilities").

                  NOW, THEREFORE, for good and valuable consideration, including
the provisions  and covenants  herein,  the receipt and  sufficiency of which is
hereby acknowledged, SAVVIS and Assignor agree as follows:

         1.  Assignor  hereby  assigns,  transfers  and  delivers  to SAVVIS the
Contracts and Liabilities and all of its right,  title and interest  therein and
delegates all of Assignor's duties and obligations  attached to the Contract and
Liabilities.

         2. SAVVIS  hereby  accepts  the  foregoing  assignment  and assumes and
agrees  to  keep,  observe,  perform,  pay and  discharge  when  due the  terms,
covenants,  conditions and obligations of Assignor  related to the Contracts and
Liabilities, and hereby releases Assignor from its obligations thereunder.

         3. Notwithstanding the foregoing, if the assignment and transfer of any
of the Contracts and Liabilities would cause a breach thereof and if no required
consent to such assignment and transfer has been obtained from the third parties
involved,  then  such  Contracts  and  Liabilities  shall  not be  assigned  and
transferred, but, instead, Assignor shall continue to hold its interests in such
Contracts and  Liabilities in trust for the benefit of SAVVIS,  shall receive in
trust and remit as promptly as possible to SAVVIS any money paid  thereunder  to
Assignor and shall cooperate in any reasonable  arrangement or action  requested
by  SAVVIS  to  secure  for  SAVVIS  all  benefits   under  such  Contracts  and
Liabilities.

         4. From and after the date of this Contract,  Assignor and SAVVIS shall
do such acts and execute such  documents  and  instruments  as may be reasonably
required to make effective the transactions  contemplated  thereby. In the event
acts  contemplated by this Agreement have not been fully effected as of the date
of this  Contract,  SAVVIS and  Assignor  will  continue  after the

                                       56
<PAGE>

date of this Contract, without further consideration,  to use their best efforts
to carry out such transactions.

         5.  Assignor  and  SAVVIS  hereby  agree  that to the extent any of the
Contracts and Liabilities  are actually  assigned to SAVVIS prior to the date of
this Contract, Assignor shall indemnify SAVVIS for any losses due to obligations
that  arose  under  such  Contracts  and  Liabilities  prior to the date of this
Contract and to the extent any of the Contracts and Liabilities are not assigned
to SAVVIS until after the date of this Contract, SAVVIS shall indemnify Assignor
for  any  losses  due  to  obligations  that  arise  under  such  Contracts  and
Liabilities following the date of this Contract.

         6. Assignor hereby agrees, from time to time, at the reasonable request
of SAVVIS,  to execute and deliver  such other  instruments  of  conveyance  and
transfer and take such other actions as SAVVIS may  reasonably  request in order
to more effectively consummate the transactions contemplated by this Contract.

         7. This  agreement  shall be governed by, and  construed in  accordance
with  the laws of  [England]  [the  State of  Missouri]  without  regard  to its
conflict of laws principles.

         [8.  Except as expressly  provided in this  Agreement,  nothing in this
Agreement  will create or confer any rights or other  benefits on or in favor of
any  person  who is not a  party  to  this  Agreement  whether  pursuant  to the
Contracts (Rights of Third Parties) Act, 1999 or otherwise.]

                  IN WITNESS  WHEREOF,  the parties  hereto have  executed  this
Contract as of the date first above written.

                          EQUIPMENT COLLOCATION PERMIT

                  This EQUIPMENT COLLOCATION PERMIT (the "Agreement") is made as
of the ____ day of _________,  2000,  by and between  [Bridge  Subsidiary]  (the
"Company") and [Savvis Subsidiary] (the "Customer").

                  WHEREAS,  the Company  occupies  the  premises  identified  on
Exhibit A attached hereto and incorporated herein by reference (the "Premises"),
which are leased by the Company under the lease  described on Exhibit B attached
hereto,  including the lease term and renewal  options  specified  therein,  and
incorporated herein by reference (the "Lease"); and

                  WHEREAS,  the Customer and the Company desire to enter into an
arrangement  permitting  the  Customer  to locate  certain of its  equipment  in
certain portions of the Premises, on and subject to the terms and conditions set
forth herein related to the Customer's collocation of the equipment;

                  NOW,  THEREFORE,  for and in consideration of the premises and
the mutual agreements herein, the parties hereby agree as follows:

1.       SPACE.

(a) To the extent  permitted by this  Agreement,  the Customer may place certain
telecommunications  equipment (the  "Equipment")  within the Premises during the
Term  (hereinafter  defined)  of this  Agreement  and may use the  Equipment  in
accordance  with the terms and  conditions  of this  Agreement and in accordance
with  applicable  laws and code. The precise  locations (the "Space") within the
Premises  where the Equipment may be placed and used by the Customer shall be as
designated  by the Company in written  notice(s)  to the  Customer.  The Company
shall maintain exclusive control over the manner and method of the placement and
use of the  Equipment  within  the  Space.  In  connection  with the  permission
established  under this  Agreement,  the Customer  shall have no  possessory  or
occupancy  rights with respect to the Space or control over the Space, but shall
have only permission to place and use the Equipment  within the Space,  together
with unrestricted access to the Equipment  twenty-four hours a day, seven days a
week.

(b) The Customer  shall use its  reasonable  best efforts to abide by applicable
terms and conditions of the Lease and any other agreements or indentures binding
on the Company  with  respect to the  Premises,  upon notice from the Company of
such  terms and  conditions  from  time to time  throughout  the Term;  and this
Agreement  and the  rights  of the  Customer  hereunder  shall  be  subject  and
subordinate  to the terms and  conditions of the Lease and other  agreements and
indentures in all respects.  The Company shall  promptly give written  notice to
the Customer of any notice of default they may receive pursuant to the Lease. If
the  Customer  shall not abide by any such  terms or  conditions,  upon 15 days'
written  notice  to  the  Customer,   the  Company  may

                                       73
<PAGE>

revoke the  permission  established  under this  Agreement  with  respect to the
applicable  Space and Premises and the Company may  terminate  the rights of the
Customer under this Agreement with respect to such Space and Premises.

(c) The Equipment and its method of installation within the Space shall, in each
instance,  be approved in writing by the Company in advance.  The Customer shall
not place any additional  equipment in the Space and shall not move or alter the
location  of the  Equipment  within  the Space  without  having  received  prior
approval in writing from the Company.

(d) Upon 30 days' prior written notice or, in the event of an emergency,  within
such shorter time as may be reasonably  determined  appropriate  by the Company,
the  Company may require the  Customer  to  relocate  the  Equipment  within the
Premises and may  redesignate the Space for the relocated  Equipment;  provided,
however,  the site of relocation shall be prepared for installation prior to any
required  relocation  and shall afford  substantially  comparable  environmental
conditions for the Equipment and substantially  comparable  accessibility to the
Equipment. All costs of relocating the Equipment shall be borne by the Customer,
excluding, however, the cost, if any, of improving the redesignated Space.

(e) Upon  written  request of the Customer and at the  Customer's  expense,  the
Customer may require that fencing,  caging, cabinets or other similar protective
covering for the Equipment be installed if (i) there is  sufficient  room in the
applicable Space and Premises for such  installations,  (ii) such  installations
will not unreasonably  interfere with the Company's use,  occupancy or planning,
and  will  not  unreasonably  interfere  with  the  Company's  equipment  or the
equipment of other  collocators,  and (iii) with respect to any Premises subject
to the Lease or other agreements or indentures, such installations are permitted
under the terms and conditions of the Lease or other agreements or indentures.

(f)  If the  placement  or use of the  Equipment  in the  Space  results  in any
violation  or claim of  violation  of any of the  Lease or other  agreements  or
indentures,  then in the event the Company shall be unable, at a cost acceptable
to the  Company,  to cure such  violation  or  secure a waiver of such  claim of
violation,  the  Company  may  undertake  to find other  suitable  space for the
Equipment  within the applicable  Space and Premises and relocate such Equipment
to other suitable location for the balance of the Term of this Agreement.

2.       TERM.

(a) The initial term (the "Initial  Term") of the permission  established  under
this Agreement  pertaining to the placement and use of the Equipment  within the
Space shall commence on the date hereof and shall continue thereafter until such
time as the  applicable  Lease expires.  If the term of the applicable  Lease is
extended,  then the Customer shall have the option, upon prior written notice to
the  Company,  to renew this  Agreement  for an  additional  term (the  "Renewal
Term"), which Renewal Term shall be conterminous with the term of the applicable
extended term under the Lease,  on the terms and conditions  otherwise set forth
in  this  Agreement.  The  Initial  Term  and the  Renewal  Term  are  sometimes
collectively  referred  to as the  "Term."  Notwithstanding  anything  herein or
elsewhere  to the  contrary,  however,  the Term  shall be  subject  to  earlier
termination as may be provided herein.

                                       74
<PAGE>

(b) The option to renew this  Agreement  with respect to the  Premises  shall be
contingent on the Company's continued occupation and ownership or leasing of the
Premises and shall be contingent  upon the Customer's  compliance with the terms
and conditions of this Agreement. In the event the Company shall cease to occupy
any of the Premises or shall default under this  Agreement,  the option to renew
this  Agreement  shall  expire with  respect to the  applicable  Premises or the
entirety of the Premises, as the case may be.

(c)  Following the  expiration of the Term,  this  Agreement  shall  continue in
effect on a  month-to-month  basis upon the same terms and conditions  otherwise
set forth  herein,  unless and until  terminated  by either the  Customer or the
Company upon at least 30 days' prior written notice to the other.

(d)  Notwithstanding  anything herein or elsewhere to the contrary,  the Company
reserves the right,  in its  discretion,  to revoke the  permission  established
under this Agreement  with respect to the  applicable  Space within any Premises
and to terminate  the rights of Customer  under this  Agreement  with respect to
such Space and Premises  immediately  upon written notice in the event that, for
whatever reason,  the Company loses its right to occupy the applicable  Premises
or its right to permit the collocation of Equipment within such Premises. In the
event the  Company  elects to exercise  its right to  terminate  the Lease,  the
Company shall give the Customer 6 months  written  notice of its  termination of
the Lease and the intended resulting termination of this Agreement.

3. CONSIDERATION.  The Customer agrees to pay the Company such amounts as may be
set forth on the Collocate  Schedule for the permission  established  under this
Agreement with respect to the scheduled  Space and Premises.  Such amounts shall
be payable  in equal  monthly  installments  in advance on the first day of each
calendar month during the Term.

4.  CONDITION OF THE  PREMISES.  The  Customer  approves the Premises in "as is"
condition as of the date of this Agreement,  and  acknowledges  that the Company
has no obligation to make alterations, improvements or additions, decorations or
changes  within the  Premises or the Space.  The Company  acknowledges  that the
Equipment is personal  property of the Customer and not a fixture,  and that the
Company shall not have any lienable interest in the Equipment.

5. ASSIGNMENT. The Agreement is personal to the parties, and may not be assigned
by either party without the prior written consent of the other.

6.  TERMINATION  OR  EXPIRATION.  At the  expiration  of the  Term  (or  earlier
termination of this Agreement), the Customer shall remove the Equipment from the
Premises  at the  Customer's  expense,  and the Space  shall be  restored by the
Company,  at the Customer's  expense (such expense to be defrayed by reimbursing

[amount]                                                     St. Louis, Missouri
                                                             _____________, 2000

                  The undersigned, SAVVIS Communications Corporation, a Missouri
corporation,  (hereinafter referred to as "Maker"), for value received, promises
to pay to the order of Bridge Information  Systems,  Inc. (the "Payee"),  at its
office located at 717 Office  Parkway,  St. Louis,  Missouri  63141,  or at such
other  place as may be  designated  in writing by the holder  hereof,  in lawful
money of the United  States of  America  in  immediately  available  funds,  the
principal  sum  of   _______________________________   United   States   Dollars
(US$_________________),  together with interest thereon from the date hereof, at
the rate or rates hereinafter specified, as follows:

                   1.  Interest.  This Note shall bear interest on the aggregate
unpaid  principal  amount  thereof  from the date  hereof at the  fixed  rate of
interest equal to ten percent (10%) per annum.

                   2. Interest and Principal Payments; Maturity. This Note shall
be payable as  follows:

                           (a) Interest shall be payable  semi-annually  in cash
on each _____ and commencing on _______________, 2000.;

                           (b) On ________________, 2003, the Maker shall pay to
the Payee a final  installment  of principal  and interest in an amount equal to
the sum of the  principal  balance  of this  Note  together  with the  remaining
accrued and unpaid interest thereon.

                   3.  Calculation  of  Interest.   The  interest  rate  payable
hereunder shall be calculated on the basis of twelve (12) thirty (30) day months
over a year of 360 days.

                   4. Application of Payments.  All installments  paid hereunder
shall be in currently available funds.

                   5. Payments Due on Saturdays,  Sundays or Legal Holidays.  If
any payment of  principal or interest due on this Note is payable on a day which
is a  Saturday,  Sunday or legal  holiday  in the state of  Missouri,  then such
payment shall be due on the next  business  day, the amount of such payment,  in
such case, to include all interest accrued to the date of actual payment.

<PAGE>

                   6. Voluntary Prepayment.  The indebtedness  evidenced by this
Note may be  prepaid,  in whole or in part,  at any time  without  premium.  All
prepayments  shall be applied  first to accrued  interest and the balance to the
reduction of the principal. No prepayment shall obligate Payee to re-advance any
sums prepaid.

                   7. Mandatory  Prepayment.  If the Maker receives an "Infusion
of Capital" of three hundred million United States dollars (U.S.$300,000,000.00)
or more in the  aggregate,  then it shall reduce the  principal  balance of this
Note by an amount  equal to no less than  fifty  percent  (50%) of the excess of
such infusions above $300 million;  provided,  however,  if the Maker's board of
directors  reasonably  determine  that  Maker has  insufficient  funding to meet
estimated cash requirements for the ensuing 18 months,  then no prepayment shall
be required.  "Infusion of Capital" means any issuance of equity in exchange for
cash, and thus excluding acquisitions and stock options.

                   8. Default Rate of Interest.  After maturity, by acceleration
or otherwise,  this Note shall bear interest at a rate equal to fifteen  percent
(15%) per annum ("Default  Rate").  Should Maker fail to make any payment hereon
on the date on which it shall  fall due,  or should  any  default be made in the
performance by Maker or any affiliated entity of Maker of any of the agreements,
conditions,  covenants, provisions or stipulations contained in this Note or any
material agreements, conditions, covenants, provisions or stipulations contained
in any other  documents  securing or executed in connection with this Note, then
the holder of this Note, at its option and without notice or demand, may declare
immediately  due and payable the entire unpaid  balance of principal  under this
Note,  together  with all  accrued  interest  thereon and after the date of such
default  this Note shall bear  interest  at the Default  Rate.  In such case the
holder of this Note may also  recover  all costs of suit and other  expenses  in
connection with efforts to collect any of the aforesaid  amounts,  together with
attorneys' fees (including  attorneys'  fees for  representation  in proceedings
under the  Bankruptcy  Code),  regardless  of whether  litigation  is commenced,
together  with  interest on any judgment  obtained by the holder of this Note at
the Default Rate, including interest at the Default Rate from and after the date
of any foreclosure  sale until actual payment is made to the holder of this Note
of the full amount due such holder.

                   9. Oral  Agreements.  Oral  agreements or commitments to loan
money,  extend credit or to forbear from enforcing repayment of a debt including
promises  to  extend or renew  such debt are not  enforceable.  To  protect  you
(Maker) and us (Payee) from  misunderstanding or disappointment,  any agreements
we reach  covering  such  matters are  contained in this  writing,  which is the
complete and exclusive  statement of the agreement  between us, except as we may
later agree in writing to modify it.

                   10.   Governing  Law.  This  Agreement   shall  be  construed
according to and governed by the laws of the State of Missouri.

           Schedules 1 and 2 but before the Effective  Date which  comprise part

           specified  in  Schedule  3. To the  extent  the  Assets  are  revised
           pursuant to Clause  2.2,  the  Consideration  set forth in Schedule 3
           shall be adjusted  based on the net book value on the Effective  Date

           3  within  fifteen  days  after  the  Effective  Date,  or as soon as
           practical  thereafter.  The parties shall  negotiate in good faith to
           finalize  such revised  Schedule and shall  provide to each other any
           information  or  records   reasonably   necessary  to  finalize  such
           Schedule.

           3.2 The  Consideration  shall  be due and  payable  as set  forth  in
           Schedule 3.

           3.3 The amount set forth in Schedule 3 is  exclusive  of VAT, and any
           and  all  transfer  or  other  taxes  or  duties  applicable  to  the

           agrees to pay.

           Security  Interest  upon  any of the  Assets  and  except  where  the
           violation,  conflict,  breach,  default,  acceleration,  termination,
           modification,  cancellation,  failure to give notice, or a lien would
           not impair the value of use of the Assets or have a material  adverse
           effect on  ability  of the  parties to  consummate  the  transactions
           contemplated  by  this  Agreement,  neither  the  execution  and  the
           delivery of this Agreement nor the  consummation of the  transactions
           contemplated hereby by the Seller will:

                  (a)  violate  any  constitution,  statute,  regulation,  rule,
           injunction,   judgment,  order,  decree,  ruling,  charge,  or  other
           restriction of any government, governmental agency, or court to which
           the Seller is subject or any  provision  of the  charter or bylaws of
           the Seller,

           arrangement to which the Seller is a party or by which they are bound
           or to which any of the Assets are subject; or

                                       87
<PAGE>

                  (c)  require  Seller to give any  notice  to,  make any filing
           with, or obtain any authorization,  consent, or approval of any third

           commissions  to any  broker,  finder,  or agent  with  respect to the
           transactions contemplated by this Agreement for which the Buyer could
           become liable or obligated.

           4.5 The Seller has good title to, or a valid  leasehold  interest  in
           the Assets,  free and clear of all Impermissible  Security  Interest,
           and there  exists no  material  restriction  on the  transfer of such
           property.

           4.6 Each of the  Contracts  with respect to the Assets is a valid and
           binding obligation of the parties thereto,  enforceable in accordance
           with terms,  in full force and effect.  No party to any such contract
           is in material  breach or  violation  thereof or default  thereunder.
           Except for matters which would not, in the aggregate, have a material
           adverse effect on the Assets,  no event has occurred  which,  through
           the  passage  of  time  or the  giving  of  notice,  or  both,  would
           constitute,  and  neither the  execution  of this  Agreement  nor the
           consummation  of the  transactions  contemplated  hereby  do or  will
           constitute  or result in, a breach or violation  of or default  under
           any contract,  or would cause the  acceleration  of any obligation of
           any party  thereto  or the  creation  of any  Impermissible  Security
           Interest upon the Assets.

           4.7 EXCEPT AS EXPRESSLY  SET FORTH IN THIS CLAUSE 4, THE SELLER MAKES
           NO  REPRESENTATION  OR  WARRANTY,  EXPRESS OR  IMPLIED,  AT LAW OR IN

           SPECIFICALLY  SET FORTH IN THIS CLAUSE 4, THE BUYER IS PURCHASING THE
           ASSETS ON AN "AS-IS, WHERE-IS" BASIS. WITHOUT LIMITING THE GENERALITY
           OF THE  FOREGOING,  THE SELLER  MAKES NO  REPRESENTATION  OR WARRANTY
           REGARDING ANY ASSETS OTHER THAN THE ASSETS BEING PURCHASED  HEREUNDER
           OR ANY LIABILITIES OTHER THAN THE LIABILITIES ASSUMED HEREUNDER,  AND
           NONE SHALL BE IMPLIED AT LAW OR IN EQUITY.

                               SUBLEASE AGREEMENT

         THIS  SUBLEASE  AGREEMENT  ("Sublease")  is made as of the  ____ day of
January,  2000 (the "Effective Date"), by and between BRIDGE INFORMATION SYSTEMS
AMERICA,  INC., a Delaware corporation  ("Sublessor") and SAVVIS  COMMUNICATIONS
CORPORATION, a Missouri corporation ("Sublessee").

         WHEREAS,  Sublessor  entered into a Master Lease  Agreement,  a copy of
which is  attached  hereto  as  EXHIBIT A (the  "Master  Lease"),  with  General
Electric  Capital  Corporation for itself and as Agent for certain  Participants
(collectively, the "Lessor"); unless otherwise defined herein, capitalized terms
used as defined  terms  shall  have the  meaning  assigned  to such terms in the
Master Lease;

         WHEREAS,  in  conjunction  with the planned  spin-off of  Sublessee  by
Sublessor,  Sublessor  has  obtained  the consent of Lessor,  a copy of which is
attached hereto as EXHIBIT B, to enter into a sublease with Sublessor; and

         WHEREAS,  Sublessor and Sublessee  desire to set  forth  in writing the
terms and conditions of the sublease;

         NOW,  THEREFORE,  in  consideration  of the  recitals  and  the  mutual
covenants,  representations,  warranties,  conditions and  agreements  hereunder
expressed, Sublessor and Sublessee agree as follows:

I.       SUBLEASING ARRANGEMENT:

         Sublessor  agrees to lease to Sublessee,  and Sublessee agrees to lease
from  Sublessor,  the  equipment  (the  "Equipment")  described in the equipment
schedules attached hereto as EXHIBIT C (the "Equipment  Schedules"),  subject to
the terms set forth herein and in the Equipment Schedules.

II.      TERM, RENT AND PAYMENT:

         (a) The term of this  Sublease (the "Term") with respect to any item of
the Equipment shall be the remaining term for such Equipment as set forth in the
Master Lease and the Equipment Schedules; provided, however, that the Term shall
begin effective from and after the Effective Date hereof.

         (b) Rent  shall be paid  directly  to  Sublessor  by wire  transfer  of
immediately  available  funds to:  Bankers  Trust New York,  New York,  New York
10006, Account No. 50-202-962, ABA No. 021-001-033,  or to such other account as
Sublessor may direct in writing;  and shall be effective upon receipt.  Payments
of Rent shall be in the amount set forth in,  and due in  accordance  with,  the
provisions  of  the  applicable   Equipment  Schedules  and  the  other  related
provisions  contained in the  schedules to the Master Lease  (together  with the

                                       97
<PAGE>

Equipment Schedules, individually and collectively, the "Schedules"). If Rent is
not paid  within  ten (10)  days of its due  date,  Sublessee  agrees  to pay to
Sublessor a late charge of Five Cents ($0.05) per dollar on, and in addition to,
the amount of such Rent but not exceeding the lawful maximum, if any.

         (c) Except as provided for in (d) below,  Sublessee  shall pay Rent, as
provided for herein without deduction or set-off.  In the event of a non-payment
of Rent by  Sublessee,  Sublessor  may continue to make  payments to Lessor with
respect to the  Equipment,  with the right to set-off any such payments  against
amounts due by the Sublessor or any of its affiliates to Sublessee or any of its
affiliates under any agreement.

         (d) In the event of a default on the  Master  Lease by  Sublessor  with
respect to the Equipment, Sublessee shall have the right to act to cure any such
default,  with the right to set-off the costs associated with curing such breach
against  amounts  due to  Sublessor  under this  Sublease  or against  any other
amounts due by  Sublessee  or any of its  affiliates  to Sublessor or any of its
affiliates under any agreement.

III.     TAXES:

         Sublessee  shall  have no  liability  for taxes  imposed  by the United
States of America or any State or political  subdivision thereof which are on or
measured by the net income of Lessor or  Sublessor.  Sublessee  shall report (to
the extent that it is legally  permissible)  and pay  promptly  all other taxes,
fees and assessments due, imposed,  assessed or levied against any Equipment (or
the  purchase,  ownership,  delivery,  leasing,  possession,  use  or  operation
thereof),  this Agreement (or any rentals or receipts hereunder),  any Schedule,
Lessor,  Sublessor  or  Sublessee  by  any  foreign,  federal,  state  or  local
government or taxing  authority during or related to the term of this Agreement,
including, without limitation, all license and registration fees, and all sales,
use, personal property, excise, gross receipts, franchise, stamp or other taxes,
imposts,  duties and charges,  together  with any  penalties,  fines or interest
thereon (all hereinafter  called "Taxes").  Sublessee shall (i) reimburse Lessor
and/or  Sublessor,  as  appropriate  (on an  after-tax  basis),  upon receipt of
written request for  reimbursement  for any Taxes charged to or assessed against
Lessor or  Sublessor;  (ii) on request  of Lessor  and/or  Sublessor,  submit to
Lessor and/or Sublessor, as appropriate, written evidence of Sublessee's payment
of Taxes, (iii) on all reports or returns show the ownership of the Equipment by
Lessor, and (iv) send a copy thereof to Lessor and Sublessor.

IV.      REPORTS:

         (a) Sublessee  will notify  Sublessor in writing,  within ten (10) days
after  any  tax or  other  lien  shall  attach  to any  Equipment,  of the  full
particulars  thereof and of the  location of such  Equipment on the date of such
notification.

         (b) Sublessee will permit Lessor and Sublessor to inspect the Equipment
and all  maintenance  records with respect  thereto during normal business hours
upon reasonable notice.

         (c) Subject to the following  sentence,  Sublessee will ensure that the
Equipment is located at the  Equipment  Location  (specified  in the  applicable
Schedule) within the Continental United States. Sublessee may move the Equipment
from the  Equipment  Location to a new location  within the  Continental  United
States  provided  that,  within  five (5) days  after  the end of each  calendar
quarter: (i) Sublessee shall provide to Sublessor written notice identifying the
Equipment  which has been relocated  during the immediately  preceding  calendar
quarter,  the old Equipment  Location and the new Equipment  Location;  and (ii)
Sublessee   shall  deliver  to  Sublessor  such  documents  and  instruments  as
reasonably  may be  required  by Lessor or  Sublessor  in  connection  with such
relocation,  including  (without  limitation)  Uniform Commercial Code Financing
Statements and (if required by Lessor or Sublessor) Estoppel/Waiver  Agreements,
to be filed at  Sublessee's  expense.  Upon  Lessor's  or  Sublessor's  request,
Sublessee  promptly  will  notify  Lessor  and/or  Sublessor  in  writing of the
location of any Equipment as of the date of such notification.

         (d) Sublessee will promptly and fully report to Sublessor in writing if
any Equipment is lost or damaged (where the estimated  repair costs would exceed
ten percent (10%) of its then fair market value), or is otherwise involved in an
accident causing personal injury or property damage.

         (e) Within thirty (30) days after any request by Lessor and  Sublessor,
Sublessee  will furnish to Sublessor a certificate  of an authorized  officer of
Sublessee  stating that he has reviewed the activities of Sublessee and that, to
the best of his knowledge,  there exists no Default (as hereinafter  defined) or
event  which,  with the giving of notice or the lapse of time (or  both),  would
become a Default.

V.       USE AND MAINTENANCE:

         (a)  Sublessee  agrees  that the  Equipment  will be used by  Sublessee
solely  in the  conduct  of its  business  and in a  manner  complying  with all
applicable  Federal,  state and local laws and  regulations  and any  applicable
insurance policies, and Sublessee shall not discontinue use of the Equipment.

         (b) Sublessee  will keep the Equipment  free and clear of all liens and
encumbrances other than those which result from acts of Lessor or Sublessor.

VI.      SERVICE:

         (a)  Sublessee  will,  at its  sole  expense,  maintain  each  unit  of
Equipment  in  good  operating  order,  repair,   condition  and  appearance  in
accordance with  manufacturer's  recommendations,  normal wear and tear excepted
and  Sublessee's  standard  practices  (but  in  no  event  less  than  industry
practices).  Sublessee's  maintenance  programs  shall be  subject to review and
approval by Lessor and Sublessor.  Sublessee  shall,  if at any time  reasonably
requested by Lessor or Sublessor,  affix in a prominent position on each unit of
Equipment plates,  tags or other identifying labels showing the interest therein
of Lessor and Sublessor.

                                       99
<PAGE>

         (b) Sublessee will not,  without the prior consent of Sublessor,  affix
or install any accessory,  equipment or device on any Equipment if such addition
will impair the value,  originally  intended  function or use of such Equipment.
All additions,  repairs, parts, supplies,  accessories,  equipment,  and devices
furnished,  attached or affixed to any Equipment which are not readily removable
shall be made only in compliance with applicable law, including Internal Revenue
Service guidelines, shall be free and clear of all liens, encumbrances or rights
of others, and shall become the property of Lessor.  Sublessee will not, without
the prior written  consent of Sublessor and subject to such conditions as Lessor
or Sublessor may impose for its protection, affix or install any Equipment to or
in any other personal or real property.

         (c) Any alterations or  modifications to the Equipment that may, at any
time  during  the  term of this  Agreement,  be  required  to  comply  with  any
applicable law, rule or regulation shall be made at the expense of Sublessee.

VII.     STIPULATED LOSS VALUE:

         Sublessee  shall promptly and fully notify  Sublessor in writing if any
unit of  Equipment  shall  be or  become  worn  out,  lost,  stolen,  destroyed,
irreparably damaged in the reasonable determination of Sublessee, or permanently
rendered  unfit  for use  from  any  cause  whatsoever  (such  occurrence  being
hereinafter  called  "Casualty  Occurrences").  On the rental  payment date next
succeeding a Casualty  Occurrence  (the  "Payment  Date"),  Sublessee  shall pay
Sublessor the sum of (x) the  Stipulated  Loss Value of such unit  calculated in
accordance  with Annex D to the Master Lease,  which is  incorporated  herein by
reference as of the rental payment date next preceding such Casualty  Occurrence
("Calculation  Date");  and (y) all  rental  and  other  amounts  which  are due
hereunder as of the Payment Date. In addition to the amounts required to be paid
by Sublessee on any Rent Payment Date pursuant to the preceding  clauses (x) and
(y),  Sublessee shall also pay to Sublessor the amount of any swap breakage loss
incurred by Lessor and/or any Participant (as such term is hereinafter  defined)
as a result of or in connection  with such payment on such Rent Payment Date. As
used herein, "Swap Breakage Loss" shall include LIBOR and other funding breakage
costs,  if any, and may be determined by Lessor and any Participant by reference
to the Standard  International Swap Dealers Association  calculation for "Loss."
Upon  payment of all sums due  hereunder,  the term of this  Sublease as to such
unit shall  terminate  and  (except in the case of the loss,  theft or  complete
destruction of such unit) Lessor shall be entitled to recover possession of such
unit.

VIII.    LOSS OR DAMAGE:

         Sublessee  hereby  assumes  and shall bear the entire risk of any loss,
theft,  damage  to, or  destruction  of,  any unit of  Equipment  from any cause
whatsoever from the time the Equipment is shipped to Sublessee.

IX       INSURANCE.

         Sublessee agrees, at its own expense, to keep all Equipment insured for
such amounts as specified in the Equipment Schedules and against such hazards as
Lessor or Sublessor may

                                      100
<PAGE>

require,  including, but not limited to, insurance for damage to or loss of such
Equipment  and  liability  coverage  for  personal  injuries,  death or property
damage,  with Lessor named as additional  insured and with a loss payable clause
in favor of Lessor,  as its interest may appear,  irrespective  of any breach of
warranty or other act or omission of Sublessee.  All such policies shall be with
companies, and on terms, satisfactory to Lessor and Sublessor.  Sublessee agrees
to  deliver  to  Sublessor  evidence  of  insurance  satisfactory  to Lessor and
Sublessor.  No insurance shall be subject to any co-insurance clause.  Sublessee
hereby appoints Lessor as Sublessee's attorney-in-fact to make proof of loss and
claim for  insurance,  and to make  adjustments  with  insurers  and to  receive
payment of and execute or endorse all documents,  checks or drafts in connection
with payments made as a result of such insurance policies. Any expense of Lessor
and Sublessor in adjusting or collecting  insurance shall be borne by Sublessee.
Sublessee  will not make  adjustments  with insurers  except (i) with respect to
claims for damage to any unit of Equipment  where the repair costs do not exceed
ten percent  (10%) of such unit's fair market  value,  or (ii) with  Lessor's or
Sublessor's written consent.  Said policies shall provide that the insurance may
not be altered or canceled by the insurer  until after thirty (30) days' written
notice to Lessor and Sublessor.  Sublessee may, at its option, apply proceeds of
insurance,  in whole or in part,  to (i)  repair  or  replace  Equipment  or any
portion  thereof,  or (ii)  satisfy any  obligation  of  Sublessee  to Lessor or
Sublessor hereunder.

X.       RETURN OF EQUIPMENT:

         (a)  Upon  any  expiration  or  termination  of this  Agreement  or any
Schedule, Sublessee shall promptly, at its own cost and expense: (i) perform any
testing and repairs  required to place the  affected  units of  Equipment in the
same condition and appearance as when received by Sublessee (reasonable wear and
tear excepted) and in good working order for their originally  intended purpose;
(ii) if deinstallation,  disassembly or crating is required, cause such units to
be  deinstalled,   disassembled  and  crated  by  an  authorized  manufacturer's
representative  or such other service person as is satisfactory  to Lessor;  and
(iii)  return such  units,  free and clear of all liens and  encumbrances,  to a
location within the continental United States as Lessor shall direct.

         (b)  Until  Sublessee  fully  has  complied  with the  requirements  of
Paragraph  (a)  above,   Sublessee's  Rent  payment  obligation  and  all  other
obligations   under  this   Agreement   shall   continue  from  month  to  month
notwithstanding  any  expiration  or  termination  of the  Term.  Sublessor  may
terminate  such  continued  leasehold  interest  upon ten (10)  days'  notice to
Sublessee.  In addition to these  rents,  Sublessor  shall have all of its other
rights and remedies available as a result of this nonperformance.

XI.      DEFAULT:

         (a)  Lessor or  Sublessor  may in writing  declare  this  Agreement  in
default ("Default") if: (1) Sublessee breaches its obligation to pay Rent or any
other  sum when due and  fails to cure the  breach  within  ten (10)  days;  (2)
Sublessee breaches any of its insurance  obligations under SECTION IX hereof, or
Sublessee  fails to comply with the  provisions  of SECTION  XXIII of the Master
Lease; (3) Sublessee  breaches any of its other obligations  hereunder and fails
to cure that breach within thirty (30) days after written  notice  thereof;  (4)
any  representation  or  warranty

                                      101
<PAGE>

made by Sublessee in connection with this Agreement shall be false or misleading
in any  material  respect;  (5)  Sublessee  becomes  insolvent  or  ceases to do
business as a going concern; (6) any Equipment is illegally used; (7) a petition
is filed by or against Sublessee under any bankruptcy or insolvency laws and, if
such petition is filed against Sublessee,  such petition is not dismissed within
ninety (90) days; (8) Sublessee shall have  terminated its corporate  existence,
consolidated  with, merged into, or conveyed or leased  substantially all of its
assets as an  entirety  to any person  (such  actions  being  referred  to as an
"Event"),  unless not less than sixty  (60) days prior to such  Event:  (x) such
person is  organized  and  existing  under the laws of the United  States or any
state, and executes and delivers to Lessor and Sublessor an agreement containing
an effective  assumption by such person of the due and punctual  performance  of
this Sublease;  and (y) Lessor and Sublessor are reasonably  satisfied as to the
creditworthiness  of such person;  (9) effective  control of Sublessor's  voting
capital stock,  issued and outstanding from time to time, is not retained by the
present  stockholders  (unless  Sublessee  shall have provided  sixty (60) days'
prior  written  notice to  Sublessor of the  proposed  disposition  of stock and
Lessor and Sublessor shall have consented thereto in writing).  Any provision of
this  Agreement  to the  contrary  notwithstanding,  Lessor  and  Sublessor  may
exercise all rights and remedies  hereunder  independently  with respect to each
Schedule.

         (b) After  Default,  at the request of Lessor,  Sublessee  shall comply
with the provisions of SECTION X(A) hereof.  Sublessee hereby  authorizes Lessor
to enter,  with or without legal  process,  any premises  where any Equipment is
located and take possession  thereof.  Sublessee shall,  without further demand,
forthwith pay to Lessor (i) as liquidated  damages for loss of a bargain and not
as a  penalty,  the  Stipulated  Loss  Value  of the  Equipment  (calculated  in
accordance  with Annex D to the Master  Lease as of the Rent  Payment  date next
preceding the declaration of default), and (ii) all Rent and other sums then due
hereunder.  Lessor may,  but shall not be required  to,  sell the  Equipment  at
private or public  sale,  in bulk or in  parcels,  with or without  notice,  and
without  having the  Equipment  present at the place of sale; or Lessor may, but
shall not be required to, lease,  otherwise  dispose of or keep idle all or part
of the Equipment;  and Lessor may use Sublessee's premises for any or all of the
foregoing without liability for rent, costs, damages or otherwise.  The proceeds
of sale, lease or other  disposition,  if any, shall be applied in the following
order of  priorities:  (1) to pay all of Lessor's  costs,  charges and  expenses
incurred  in  taking,  removing,  holding,  repairing  and  selling,  leasing or
otherwise disposing of Equipment; then, (2) to the extent not previously paid by
Sublessee,  to pay Lessor  all sums due from  Sublessee  hereunder;  then (3) to
reimburse  to Sublessee  any sums  previously  paid by  Sublessee as  liquidated
damages; and (4) any surplus shall be remitted to Sublessee. Sublessee shall pay
any deficiency in clauses (1) and (2) forthwith.

         (c) In addition  to the  foregoing  rights,  after  Default,  Lessor or
Sublessor may terminate the lease as to any or all of the Equipment.

         (d) The foregoing  remedies are cumulative,  and any or all thereof may
be  exercised in lieu of or in addition to each other or any remedies at law, in
equity,  or under statute.  Sublessee waives notice of sale or other disposition
(and the time and place thereof),  and the manner and place of any  advertising.
If permitted by law,  Sublessee  shall pay reasonable  attorney's  fees actually
incurred by Lessor and  Sublessor in enforcing  the  provisions of this Sublease
and any

                                      102
<PAGE>

ancillary documents. Waiver of any Default shall not be a waiver of any other or
subsequent default.

         (e) Any default under the terms of any other material agreement between
Sublessor  and  Sublessee  or  any  of  their  affiliates  giving  rise  to  the
termination of such other agreement may be declared by Sublessor a default under
this agreement.

XII.     ASSIGNMENT:

         (a) SUBLESSEE  SHALL NOT ASSIGN,  MORTGAGE,  SUBLET OR HYPOTHECATE  ANY
EQUIPMENT  OR THE  INTEREST OF  SUBLESSEE  HEREUNDER  WITHOUT THE PRIOR  WRITTEN
CONSENT OF SUBLESSOR.

         (b)  Sublessor may not,  without the consent of Sublessee,  assign this
Agreement or any Schedule, or the right to enter into any Schedule, such consent
not  to be  unreasonably  withheld.  In the  event  of a  permitted  assignment,
Sublessee  agrees that it will pay all Rent and other amounts payable under each
Schedule  to the  Sublessor  named  therein;  provided,  however,  if  Sublessee
receives written notice of an assignment from Sublessor,  Sublessee will pay all
Rent and other amounts  payable under any assigned  Schedule to such assignee or
as instructed by Sublessor. Each Schedule,  incorporating by reference the terms
and conditions of this  Agreement,  constitutes a separate  instrument of lease,
and the  Sublessor  named  therein  or its  assignee  shall  have all  rights as
"Sublessor"  thereunder  separately  exercisable  by  such  named  Sublessor  or
assignee as the case may be,  exclusively and  independently of Sublessor or any
assignee with respect to other Schedules  executed  pursuant  hereto.  Sublessee
further  agrees to  confirm  in writing  receipt  of a notice of  assignment  as
reasonably may be requested by assignee.

         (c)  Sublessee  acknowledges  that it has  been  advised  that  General
Electric Capital  Corporation is acting under the Master Lease for itself and as
agent  for  certain  third   parties  (each  being  herein   referred  to  as  a
"Participant" and,  collectively,  as the "Participants");  that the interest of
the Lessor in the Master Lease, the Equipment Schedules, related instruments and
documents  and/or the Equipment may be conveyed to, in whole or in part, and may
be used as security  for  financing  obtained  from,  one or more third  parties
without  the  consent  of  Sublessee  (the   "Syndication").   Sublessee  agrees
reasonably  to  cooperate  with  Lessor and  Sublessor  in  connection  with the
Syndication,  including  the  execution  and  delivery of such other  documents,
instruments,  notices, opinions,  certificates and acknowledgments as reasonably
may be required by Lessor, Sublessor or such Participant;  provided,  however in
no event  shall  Sublessee  be  required  to consent  to any  change  that would
adversely  affect any of the  economic  terms of the  transactions  contemplated
herein.

         (d)  Subject  always to the  foregoing,  this  Agreement  inures to the
benefit  of, and is binding  upon,  the  successors  and  assigns of the parties
hereto.

XIII.    INDEMNIFICATION:

                                      103
<PAGE>

         (a)  Sublessee  hereby  agrees to  indemnify,  save and keep  harmless,
Lessor and Sublessor, their agents, employees,  successors and assigns, from and
against any and all losses, damages,  penalties,  injuries,  claims, actions and
suits,  including legal expenses,  of whatsoever kind and nature, in contract or
tort, whether caused by the active or passive negligence of Lessor or otherwise,
and including,  but not limited to, Lessor's strict  liability in tort,  arising
out of (i) the  selection,  manufacture,  purchase,  acceptance  or rejection of
Equipment, the ownership of Equipment during the Term, and the delivery,  lease,
possession,  maintenance,  uses, condition, return or operation of the Equipment
(including,  without  limitation,  latent  and  other  defects,  whether  or not
discoverable  by Sublessor or Sublessee  and any claim for patent,  trademark or
copyright  infringement  or  environmental  damage),  or (ii) the  condition  of
Equipment sold or disposed of after use by Sublessee, any sublessee or employees
of Sublessee.  Sublessee  shall,  upon request,  defend any actions based on, or
arising out of, any of the foregoing.

         (b) All of Lessor's and Sublessor's rights,  privileges and indemnities
contained in this Section shall survive the  expiration or other  termination of
this Sublease and the Master Lease and the rights,  privileges  and  indemnities
contained herein are expressly made for the benefit of, and shall be enforceable
by Lessor, Sublessor and their successors and assigns.

XIV.     DISCLAIMER:

         SUBLESSEE  ACKNOWLEDGES  THAT IT HAS SELECTED THE EQUIPMENT WITHOUT ANY
ASSISTANCE  FROM LESSOR,  ITS AGENTS OR EMPLOYEES.  Except as may be provided in
the  Master  Establishment  and  Transition  Agreement,  between  Sublessor  and
Sublessee dated _____________, 2000 ("MEAT Agreement"), SUBLESSOR DOES NOT MAKE,
HAS NOT  MADE,  NOR  SHALL BE  DEEMED  TO MAKE OR HAVE  MADE,  ANY  WARRANTY  OR
REPRESENTATION,  EITHER EXPRESS OR IMPLIED, WRITTEN OR ORAL, WITH RESPECT TO THE
EQUIPMENT  LEASED  HEREUNDER  OR  ANY  COMPONENT  THEREOF,  INCLUDING,   WITHOUT
LIMITATION,  ANY WARRANTY AS TO DESIGN, COMPLIANCE WITH SPECIFICATIONS,  QUALITY
OF MATERIALS OR WORKMANSHIP,  MERCHANTABILITY,  FITNESS FOR ANY PURPOSE,  USE OR
OPERATION,  SAFETY, PATENT,  TRADEMARK OR COPYRIGHT INFRINGEMENT,  OR TITLE. All
such risks, as between Sublessor and Sublessee, or between Lessor and Sublessee,
are to be borne by Sublessee.  Without limiting the foregoing, and except as may
be provided in the MEAT  Agreement,  Sublessor shall have no  responsibility  or
liability to Sublessee or any other person with respect to any of the following:
(i) any  liability,  loss or damage  caused or alleged to be caused  directly or
indirectly by any Equipment,  any inadequacy  thereof,  any deficiency or defect
(latent  or  otherwise)   therein,  or  any  other  circumstance  in  connection
therewith;  (ii) the use, operation or performance of any Equipment or any risks
relating  thereto;  (iii) any  interruption  of  service,  loss of  business  or
anticipated profits or consequential  damages; or (iv) the delivery,  operation,
servicing, maintenance, repair, improvement or replacement of any Equipment. If,
and so long as, no default exists under this Sublease,  Sublessee  shall be, and
hereby is,  authorized  during the term of this Lease to assert and enforce,  at
Sublessee's sole cost and expense, from time to time, in the name of and for the
account of Lessor,  Sublessor and/or

                                      104
<PAGE>

Sublessee,  as their interests may appear,  whatever claims and rights Sublessor
or Lessor may have against any Supplier of the Equipment.

XV.      REPRESENTATIONS AND WARRANTIES OF SUBLESSEE:

         Sublessee represents and warrants to Sublessor that on the date hereof:

         (a)  Sublessee  has  adequate  power and  capacity to enter  into,  and
perform  under,  this  Agreement  and  all  related  documents  (together,   the
"Documents") and is duly qualified to do business wherever necessary to carry on
its present  business and operations,  including the  jurisdiction(s)  where the
Equipment is or is to be located.

         (b) The Documents have been duly authorized,  executed and delivered by
Sublessee and constitute  valid,  legal and binding  agreements,  enforceable in
accordance  with their  terms,  except to the  extent  that the  enforcement  of
remedies  therein  provided  may be  limited  under  applicable  bankruptcy  and
insolvency laws.

         (c) No approval,  consent or withholding of objections is required from
any governmental  authority or instrumentality with respect to the entry into or
performance  by  Sublessee  of the  Documents  except such as have  already been
obtained.

         (d) The entry into and  performance  by Sublessee of the Documents will
not: (i) violate any judgment,  order, law or regulation applicable to Sublessee
or any provision of Sublessee's  articles of incorporation,  charter or by-laws;
or (ii)  result in any breach of,  constitute  a default  under or result in the
creation of any lien,  charge,  security  interest or other encumbrance upon any
Equipment  pursuant  to any  indenture,  mortgage,  deed of trust,  bank loan or
credit  agreement  or other  instrument  (other  than this  Agreement)  to which
Sublessee is a party.

         (e) There are no suits or proceedings pending or threatened in court or
before any commission, board or other administrative agency against or affecting
Sublessee, which will have a material adverse effect on the ability of Sublessee
to fulfill its obligations under this Agreement.

be located and (ii) in such jurisdictions  where Sublessee's  ownership or lease
of property or the conduct of its business requires it to be so qualified.

XVI.     COVENANTS OF SUBLESSEE:

         Sublessee covenants and agrees as follows:

         (a)  Promptly  upon any  officer or  director  of  Sublessee  obtaining
knowledge of any  condition or event which  constitutes a default or a potential
default  hereunder,  Sublessee  shall

                                      105
<PAGE>

provide prompt written  notice to Sublessor  specifying  such condition and what
action Sublessee is taking or proposes to take with respect thereto.

         (b)  Sublessee  will  promptly  execute and deliver to  Sublessor  such
further  documents,  instruments  and assurances and take such further action as
Lessor or Sublessor from time to time may  reasonably  request in order to carry
out the intent and purpose of this  Sublease  and to  establish  and protect the
rights and  remedies  created or intended to be created in favor of Sublessor or
Lessor hereunder.

         (c) Sublessee will comply with all affirmative  and negative  covenants
set forth in Exhibits M and N to the Master Lease,  to the same extent as if set
forth herein.

         (d) Sublessee will not attach or  incorporate  any item of Equipment to
or in any other item of  equipment  or  personal  property  or to or in any real
property  in a manner  that gives rise to the  assertion  of any lien,  claim or
encumbrance  on such  item of  Equipment  by reason  of such  attachment  or the
assertion of a claim that such item of Equipment has become a fixture. Sublessee
hereby agrees that it will  purchase any such item of Equipment  which Lessor or
Sublessor  notifies Sublessee in writing is subject to the assertion of any such
lien, claim or encumbrance within [ten (10)] days of such notice.

         (e) The Equipment  will at all times be used for commercial or business
purposes.

         (f)  Sublessee  shall not take any action  that  would  cause a default
under this Sublease or the Master Lease or omit to take any action  necessary to
prevent a breach of this Sublease or the Master Lease.

XVII.    REPRESENTATIONS AND WARRANTIES OF SUBLESSOR:

         (a)  Sublessor  has  adequate  power and  capacity to enter  into,  and
perform  under,  this  Agreement  and  all  related  documents  (together,   the
"Documents") and is duly qualified to do business wherever necessary to carry on
its present  business and operations,  including the  jurisdiction(s)  where the
Equipment is or is to be located.

         (b) The Documents have been duly authorized,  executed and delivered by
Sublessor and constitute  valid,  legal and binding  agreements,  enforceable in
accordance  with their  terms,  except to the  extent  that the  enforcement  of
remedies  therein  provided  may be  limited  under  applicable  bankruptcy  and
insolvency laws.

         (c) No approval,  consent or withholding of objections is required from
any governmental  authority or instrumentality with respect to the entry into or
performance  by  Sublessor  of the  Documents  except such as have  already been
obtained.

         (d) There are no suits or proceedings pending or threatened in court or
before any commission, board or other administrative agency against or affecting
Sublessor, which will have a material adverse effect on the ability of Sublessor
to fulfill its obligations under this Agreement.

                                      106
<PAGE>

         (e)  Sublessor has not received a Notice of Default on the Master Lease
from Lessor and, to  Sublessor's  knowledge  after the  exercise of  Sublessor's
commercially  reasonable  best  efforts to  investigate  the same,  no  material
default has  occurred on the Master Lease with  respect to the  Equipment  which
could not be cured by the giving of notice or  undertaking  of other actions not
material to the market value of the Equipment taken as a whole.

XVIII.   COVENANTS OF SUBLESSOR:

         Sublessor covenants and agrees as follows:

         (a)  Sublessor  shall at all time  perform  its  obligations  under the
Master Lease with respect to the Equipment, except such covenant shall not apply
to the extent such default is due to actions or failure to act by Sublessee.

         (b)  Sublessor  shall  notify  Sublessee  in  writing  of any notice of
default which it receives from the Lessor with respect to the Equipment:  (1) if
with respect to a failure to pay rent or any other sum when due,  such notice to
be delivered  to  Sublessee no later than 2 days after  receipt of the notice of
default  received by  Sublessor,  and (2) if with respect to any other notice of
default,  such notice to be  delivered  to Sublessee no later than 10 days after
receipt of the notice of default received by Sublessor

XIX.     OWNERSHIP FOR TAX PURPOSES, GRANT OF SECURITY INTEREST; USURY SAVINGS:

         (a) For income tax purposes,  Lessor and Sublessor will treat Sublessee
as the owner of the Equipment.  Accordingly, Lessor and Sublessor will not claim
any tax benefits available to an owner of the Equipment.

         (b)  Sublessee  hereby  acknowledges  that Lessor has a first  security
interest in the Equipment, together with all additions, attachments, accessions,
accessories  and accessions  thereto whether or not furnished by the Supplier of
the Equipment and any and all substitutions, replacements or exchanges therefor,
and any and all insurance  and/or other  proceeds of the property in and against
which a security interest is granted hereunder.

         (c) It is the  intention  of the  parties  hereto  to  comply  with any
applicable usury laws to the extent that any Equipment Schedule is determined to
be subject to such laws;  accordingly,  it is agreed that,  notwithstanding  any
provision  to the contrary in any  Equipment  Schedule or this  Sublease,  in no
event shall any Equipment  Schedule require the payment or permit the collection
of interest in excess of the maximum amount  permitted by applicable law. If any
such excess interest is contracted for,  charged or received under any Equipment
Schedule or this  Sublease,  or in the event that all of the  principal  balance
shall be prepaid, so that under any of such circumstances the amount of interest
contracted for, charged or received under any Equipment Schedule or the Sublease
shall exceed the maximum amount of interest permitted by applicable

                                      107
<PAGE>

law, then in such event:  (i) the provisions of this paragraph  shall govern and
control,  (ii) neither Sublessee nor any other person or entity now or hereafter
liable  for the  payment  hereof  shall be  obligated  to pay the amount of such
interest to the extent  that it is in excess of the  maximum  amount of interest
permitted by applicable law, (iii) any such excess which may have been collected
shall be either applied as a credit against the then unpaid principal balance or
refunded to Sublessee,  at the option of the  Sublessor,  and (iv) the effective
rate of interest shall be  automatically  reduced to the maximum lawful contract
rate allowed under  applicable  law as now or hereafter  construed by the courts
having jurisdiction thereof. It is further agreed that without limitation of the
foregoing,  all calculations of the rate of interest  contracted for, charged or
received  under any  Equipment  Schedule or the Sublease  which are made for the
purpose of  determining  whether such rate exceeds the maximum  lawful  contract
rate,  shall be made, to the extent  permitted by applicable law, by amortizing,
prorating, allocating and spreading in equal parts during the period of the full
stated  term of the  indebtedness  evidenced  hereby,  all  interest at any time
contracted for,  charged or received from Sublessee or otherwise by Sublessor in
connection with such  indebtedness;  provided,  however,  that if any applicable
state law is  amended or the law of the United  States of America  preempts  any
applicable  state law,  so that it becomes  lawful  for  Sublessor  to receive a
greater interest per annum rate than is presently allowed,  the Sublessee agrees
that, on the effective date of such amendment or preemption, as the case may be,
the lawful  maximum  hereunder  shall be increased  to the maximum  interest per
annum rate allowed by the amended  state law or the law of the United  States of
America.

XX.      END OF SUBLEASE PURCHASE OPTION:

         So long as (i) no default exists under the Sublease or the Master Lease
and (ii) the Term of the  Sublease  and the  Master  Lease has not been  earlier
terminated,  Sublessee may at the  expiration of the Term of the Sublease,  upon
one hundred eighty (180) days' prior written  notice to Sublessor,  purchase all
(but not less than all) of the Equipment  described in any Schedule on an AS IS,
WHERE IS BASIS without recourse to or warranty from Sublessor or lessor, express
or implied, for a purchase price of $1.00 payable to Lessor (plus all applicable
sales taxes). The payment shall be due and payable on the expiration of the Term
of the Sublease and the Master Lease.

XXI.     MISCELLANEOUS:

         (a) SUBLESSEE HEREBY  UNCONDITIONALLY WAIVES ITS RIGHTS TO A JURY TRIAL
OF ANY  CLAIM OR CAUSE OF ACTION  BASED  UPON OR  ARISING  OUT OF,  DIRECTLY  OR
INDIRECTLY,  THIS SUBLEASE,  ANY OF THE RELATED DOCUMENTS,  ANY DEALINGS BETWEEN
SUBLESSEE  AND  SUBLESSOR OR THE LESSOR  RELATING TO THE SUBJECT  MATTER OF THIS
TRANSACTION OR ANY RELATED  TRANSACTIONS,  AND/OR THE RELATIONSHIP THAT IS BEING
ESTABLISHED  BETWEEN  SUBLESSEE  AND  SUBLESSOR.  The  scope of this  waiver  is
intended to be all encompassing of any and all disputes that may be filed in any
court (including,  without limitation,  contract claims, tort claims,  breach of
duty claims,  and all other  common law and  statutory  claims).  THIS WAIVER IS
IRREVOCABLE MEANING THAT IT MAY NOT BE MODIFIED EITHER ORALLY OR IN WRITING, AND
THE WAIVER SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS, RENEWALS, SUPPLEMENTS OR

                                      108
<PAGE>

MODIFICATIONS TO THIS SUBLEASE, ANY RELATED DOCUMENTS, OR TO ANY OTHER DOCUMENTS
OR AGREEMENTS  RELATING TO THIS TRANSACTION OR ANY RELATED  TRANSACTION.  In the
event of litigation, this Agreement may be filed as a written consent to a trial
by the court.

         (b) Any  cancellation  or  termination  by  Sublessor,  pursuant to the
provision of this Sublease, any Schedule, supplement or amendment hereto, or the
sublease of any Equipment  hereunder,  shall not release Sublessee from any then
outstanding obligations to Sublessor hereunder.

         (c) All Equipment shall at all times remain personal property of Lessor
regardless of the degree of its annexation to any real property and shall not by
reason of any  installation  in, or  affixation  to, real or  personal  property
become a part  thereof.  Sublessee  shall obtain and deliver to Sublessor (to be
recorded at Lessee's expense) from any person having an interest in the property
where the  Equipment  is to be  located,  waivers  of any lien,  encumbrance  or
interest which such person might have or hereafter  obtain or claim with respect
to the Equipment.

         (d) Time is of the essence of this  Agreement.  Sublessor's  failure at
any time to require  strict  performance  by Sublessee of any of the  provisions
hereof shall not waive or diminish Sublessor's right thereafter to demand strict
compliance therewith.

         (e)  Sublessee  agrees,  upon  Sublessor's   request,  to  execute  any
instrument  necessary  or expedient  for filing,  recording  or  perfecting  the
interest of Sublessor or Lessor.

personally delivered,  delivered by overnight courier service, sent by facsimile
transmission (with  confirmation of receipt),  or sent by certified mail, return
receipt requested, addressed to the other party at its respective address stated
above or,  with  respect to the  Lessor,  in the  Master  Lease or at such other
address as such party shall from time to time  designate in writing to the other
party, and shall be effective from the date of receipt.

         (g) This Sublease and the Schedule,  including the Equipment  Schedules
and the  schedules  to the  Master  Lease,  which  are  incorporated  herein  by
reference,  constitute the entire agreement  between the parties with respect to
the  subject  matter  hereof  and shall not be  amended or altered in any manner
except by a document  in writing  executed  by both  parties.  NO  VARIATION  OR
MODIFICATION  OF  THIS  AGREEMENT  OR ANY  WAIVER  OF ANY OF ITS  PROVISIONS  OR
CONDITIONS,  SHALL BE VALID  UNLESS  IN  WRITING  AND  SIGNED  BY AN  AUTHORIZED
REPRESENTATIVE  OF THE PARTIES HERETO.  Any provision of this Agreement which is
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  hereof,  and any such  prohibition  or
unenforceability   in  any   jurisdiction   shall  not   invalidate   or  render
unenforceable such provision in any other jurisdiction.

                                      109
<PAGE>

         (h) The  representations,  warranties and covenants of Sublessee herein
shall be deemed to survive the closing  hereunder.  The obligations of Sublessee
which accrue during the term of this  Agreement and  obligations  which by their
express  terms  survive the  termination  of this  Agreement,  shall survive the
termination of this Agreement.

         (i) In case of a failure of Sublessee  to comply with any  provision of
this Agreement,  Sublessor shall have the right, but shall not be obligated,  to
effect such  compliance,  in whole or in part; and all moneys spent and expenses
and  obligations  incurred or assumed by Sublessor in effecting such  compliance
(together  with interest  thereon at the rate specified in Paragraph (j) of this
Section) shall constitute  additional Rent due to Sublessor within five (5) days
after  the  date  Sublessor  sends  notice  to  Sublessee   requesting  payment.
Sublessor's  effecting  such  compliance  shall not be a waiver  of  Sublessee's
default.

         (j) Any Rent or other  amount  not paid to  lessor  when due  hereunder
shall bear interest,  both before and after any judgment or termination  hereof,
at the lesser of eighteen percent (18%) per annum or the maximum rate allowed by
law.

         (k) Any  provisions  in this  Agreement  and any Schedule  which are in
conflict  with any  statute,  law or  applicable  rule shall be deemed  omitted,
modified or altered to conform thereto.

         (l) So  long  as no  Default  shall  have  occurred  and be  continuing
hereunder,  and conditioned  upon Sublessee  performing all of the covenants and
conditions  hereof,  as  to  claims  of  Sublessor  or  persons  claiming  under
Sublessor,  Sublessee  shall  peaceably  and quietly  hold,  possess and use the
Equipment during the Term of this Agreement  subject to the terms and conditions
hereof.

         (m) Whether or not any Equipment is leased  hereunder,  Sublessee shall
pay upon demand as  additional  Rent  hereunder  all  reasonable  and  necessary
documented  transaction  expenses  including,  but not limited  to,  expenses of
counsel,  due diligence,  appraisals,  lien searches,  Uniform  Commercial  Code
and/or Estoppel/Waiver Agreement filing fees, and field audits.

XXII.    CHOICE OF LAW; JURISDICTION:

         THIS AGREEMENT AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES  HEREUNDER
SHALL IN ALL RESPECTS BE GOVERNED  BY, AND  CONSTRUED IN  ACCORDANCE  WITH,  THE
INTERNAL LAWS OF THE STATE OF NEW YORK  (WITHOUT  REGARD TO THE CONFLICT OF LAWS
PRINCIPLES OF SUCH STATE),  INCLUDING ALL MATTERS OF CONSTRUCTION,  VALIDITY AND
PERFORMANCE, REGARDLESS OF THE LOCATION OF THE EQUIPMENT. The parties agree that
any action or  proceeding  arising out of or relating to this  Agreement  may be
commenced in the United States  District Court for the Southern  District of New
York.

XXIII.   CHATTEL PAPER:

         To the extent that any Schedule would constitute chattel paper, as such
term is defined in the Uniform  Commercial  Code as in effect in any  applicable
jurisdiction,  no security  interest therein may be created through the transfer
or  possession  of this  Agreement  in and of itself  without  the  transfer  or
possession of the original of a Schedule executed pursuant to this Agreement and
incorporating  this  Agreement by  reference;  and no security  interest in this
Agreement  and a Schedule  may be created by the transfer or  possession  of any
counterpart  of the  Schedule  other than the original  thereof,  which shall be

           all of the property and property rights owned and ------------ leased
           by the Company and all of the property  and  property  rights that in

                     --------------------
Plan shall be administered by (A) the Board or (B) a Committee, which committee
shall be constituted to satisfy Applicable Laws.

          (b)  Powers of the Administrator.  Subject to the provisions of the
               ---------------------------
Plan, and in the case of a Committee, subject to the specific duties delegated
by the Board to such Committee, the Administrator shall have the authority, in
its discretion:

               (i)   to determine the Fair Market Value;

               (ii)  to select the Service Providers to whom Options and Stock
Purchase Rights may be granted hereunder;

               (iii) to determine the number of shares of Common Stock to be
covered by each Option and Stock Purchase Right granted hereunder;

               (iv)  to approve forms of agreement for use under the Plan;

               (v)   to determine the terms and conditions, not inconsistent
with the terms of the Plan, of any Option or Stock Purchase Right granted
hereunder. Such terms and conditions include, but are not limited to, the
exercise price, the time or times when Options or Stock Purchase Rights may be
exercised (which may be based on performance criteria), any vesting acceleration
or waiver of forfeiture restrictions, and any restriction or limitation
regarding any Option or Stock Purchase Right or the shares of Common Stock
relating thereto, based in each case on such factors as the Administrator, in
its sole discretion, shall determine;

                                      -5-
<PAGE>

               (vi)   to reduce the exercise price of any Option or Stock
Purchase Right to the then current Fair Market Value if the Fair Market Value of
the Common Stock covered by such Option or Stock Purchase Right shall have
declined since the date the Option or Stock Purchase Right was granted;

               (vii)  to institute an Option Exchange Program;

               (viii) to construe and interpret the terms of the Plan and
awards granted pursuant to the Plan;

               (ix)   to prescribe, amend and rescind rules and regulations
relating to the Plan, including rules and regulations relating to sub-plans
established for the purpose of qualifying for preferred tax treatment under
foreign tax laws;

               (x)    to modify or amend each Option or Stock Purchase Right
(subject to Section 16(c) of the Plan), including the discretionary authority to
extend the post-termination exercisability period of Options longer than is
otherwise provided for in the Plan;

               (xi)   to allow Optionees to satisfy withholding tax obligations
by electing to have the Company withhold from the Shares to be issued upon
exercise of an Option or Stock Purchase Right that number of Shares having a
Fair Market Value equal to the amount required to be withheld. The Fair Market
Value of the Shares to be withheld shall be determined on the date that the
amount of tax to be withheld is to be determined. All elections by an Optionee
to have Shares withheld for this purpose shall be made in such form and under
such conditions as the Administrator may deem necessary or advisable;

               (xii)  to authorize any person to execute on behalf of the
Company any instrument required to effect the grant of an Option or Stock
Purchase Right previously granted by the Administrator;

               (xiii) to make all other determinations deemed necessary or
advisable for administering the Plan.

          (c)  Effect of Administrator's Decision.  The Administrator's
               ----------------------------------
decisions, determinations and interpretations shall be final and binding on all
Optionees and any other holders of Options or Stock Purchase Rights.

     5.   Eligibility.  Nonstatutory Stock Options and Stock Purchase Rights may
          -----------
be granted to Service Providers.  Incentive Stock Options may be granted only to
Employees.

     6.   Limitations.
          -----------

          (a) Each Option shall be designated in the Option Agreement as either
an Incentive Stock Option or a Nonstatutory Stock Option.  However,
notwithstanding such designation, to the extent that the aggregate Fair Market
Value of the Shares with respect to which

                                      -6-
<PAGE>

Incentive Stock Options are exercisable for the first time by the Optionee
during any calendar year (under all plans of the Company and any Parent or
Subsidiary) exceeds $100,000, such Options shall be treated as Nonstatutory
Stock Options. For purposes of this Section 6(a), Incentive Stock Options shall
be taken into account in the order in which they were granted. The Fair Market
Value of the Shares shall be determined as of the time the Option with respect
to such Shares is granted.

          (b)   Neither the Plan nor any Option or Stock Purchase Right shall
confer upon an Optionee any right with respect to continuing the Optionee's
relationship as a Service Provider with the Company, nor shall they interfere in
any way with the Optionee's right or the Company's right to terminate such
relationship at any time, with or without Cause.

          (c)   The following limitations shall apply to grants of Options:

          (i)   No Service Provider shall be granted, in any fiscal year of the
Company, Options to purchase more than 1,000,000 Shares.

          (ii)  In connection with his or her initial service, a Service
Provider may be granted Options to purchase up to an additional 2,000,000
Shares, which shall not count against the limit, set forth in subsection (i)
above.

          (iii) The foregoing limitations shall be adjusted proportionately
in connection with any change in the Company's capitalization as described in
Section 14.

          (iv)  If an Option is cancelled in the same fiscal year of the Company
in which it was granted (other than in connection with a transaction described
in Section 14), the cancelled Option will be counted against the limits set
forth in subsections (i) and (ii) above.  For this purpose, if the exercise
price of an Option is reduced, the transaction will be treated as a cancellation
of the Option and the grant of a new Option.

     7.   Term of Plan.  Subject to Section 20 of the Plan, the Plan shall
          ------------
become effective upon its adoption by the Board.  It shall continue in effect
for a term of ten (10) years unless terminated earlier under Section 16 of the
Plan.

     8.   Term of Option.  The term of each Option shall be stated in the Option
          --------------
Agreement. In the case of an Incentive Stock Option, the term shall be ten (10)
years from the date of grant or such shorter term as may be provided in the
Option Agreement. Moreover, in the case of an Incentive Stock Option granted to
an Optionee who, at the time the Incentive Stock Option is granted, owns stock
representing more than ten percent (10%) of the total combined voting power of
all classes of stock of the Company or any Parent or Subsidiary, the term of the
Incentive Stock Option shall be five (5) years from the date of grant or such
shorter term as may be provided in the Option Agreement.

                                      -7-

     9.   Option Exercise Price and Consideration.
          ---------------------------------------

          (a) Exercise Price. The per share exercise price for the Shares to be
              --------------
issued pursuant to exercise of an Option shall be determined by the
Administrator, subject to the following:

              (i)  In the case of an Incentive Stock Option

                   (A) granted to an Employee who, at the time the Incentive
Stock Option is granted, owns stock representing more than ten percent (10%) of
the voting power of all classes of stock of the Company or any Parent or
Subsidiary, the per Share exercise price shall be no less than 110% of the Fair
Market Value per Share on the date of grant.

                   (B) granted to any Employee other than an Employee described
in paragraph (A) immediately above, the per Share exercise price shall be no
less than 100% of the Fair Market Value per Share on the date of grant.

              (ii) In the case of a Nonstatutory Stock Option, the per Share
exercise price shall be determined by the Administrator.  In the case of a
Nonstatutory Stock Option intended to qualify as "performance-based
compensation" within the meaning of Section 162(m) of the Code, the per Share
exercise price shall be no less than 100% of the Fair Market Value per Share on
the date of grant.

              (iii) Notwithstanding the foregoing, Options may be granted with a
per Share exercise price of less than 100% of the Fair Market Value per Share on
the date of grant pursuant to a merger or other corporate transaction.

          (b) Waiting Period and Exercise Dates.  At the time an Option is
              ---------------------------------
granted, the Administrator shall fix the period within which the Option may be
exercised and shall determine any conditions that must be satisfied before the
Option may be exercised.

          (c) Form of Consideration.  The Administrator shall determine the
              ---------------------
acceptable form of consideration for exercising an Option, including the method
of payment.  In the case of an Incentive Stock Option, the Administrator shall
determine the acceptable form of consideration at the time of grant.  Such
consideration may consist entirely of:

              (i)    cash;

              (ii)   check;

              (iii)  promissory note;

              (iv)   other Shares which (A) in the case of Shares acquired upon
exercise of an option, have been owned by the Optionee for more than six months
on the date of surrender, and (B) have a Fair Market Value on the date of
surrender equal to the aggregate exercise price of the Shares as to which said
Option shall be exercised;

                                      -8-
<PAGE>

          (v)    consideration received by the Company under a cashless exercise
program implemented by the Company in connection with the Plan;

          (vi)   a reduction in the amount of any Company liability to the
Optionee, including any liability attributable to the Optionee's participation
in any Company-sponsored deferred compensation program or arrangement;

          (vii)  any combination of the foregoing methods of payment; or

          (viii) such other consideration and method of payment for the
issuance of Shares to the extent permitted by Applicable Laws.

     10.  Exercise of Option.
          ------------------

          (a)    Procedure for Exercise; Rights as a Shareholder.  Any Option
                 -----------------------------------------------
granted hereunder shall be exercisable according to the terms of the Plan and at
such times and under such conditions as determined by the Administrator and set
forth in the Option Agreement.  Unless the Administrator provides otherwise,
vesting of Options granted hereunder shall be tolled during any unpaid leave of
absence.  An Option may not be exercised for a fraction of a Share.

                 An Option shall be deemed exercised when the Company receives:
(i) written or electronic notice of exercise (in accordance with the Option
Agreement) from the person entitled to exercise the Option, and (ii) full
payment for the Shares with respect to which the Option is exercised. Full
payment may consist of any consideration and method of payment authorized by the
Administrator and permitted by the Option Agreement and the Plan. Shares issued
upon exercise of an Option shall be issued in the name of the Optionee or, if
requested by the Optionee, in the name of the Optionee and his or her spouse.
Until the Shares are issued (as evidenced by the appropriate entry on the books
of the Company or of a duly authorized transfer agent of the Company), no right
to vote or receive dividends or any other rights as a shareholder shall exist
with respect to the Optioned Stock, notwithstanding the exercise of the Option.
The Company shall issue (or cause to be issued) such Shares promptly after the
Option is exercised. No adjustment will be made for a dividend or other right
for which the record date is prior to the date the Shares are issued, except as
provided in Section 14 of the Plan.

                 Exercising an Option in any manner shall decrease the number of
Shares thereafter available, both for purposes of the Plan and for sale under
the Option, by the number of Shares as to which the Option is exercised.

          (b)    Termination of Relationship as a Service Provider.  Subject to
                 -------------------------------------------------
Section 14, if an Optionee ceases to be a Service Provider (but not in the event
of an Optionee's change of status from Employee to Consultant (in which case an
Employee's Incentive Stock Option shall automatically convert to a Nonstatutory
Stock Option on the ninety-first (91/st/) day following such change of status)
or from Consultant to Employee), such Optionee may, but only within such period
of time as is specified in the Option Agreement (but in no event later than the
expiration date of the term of such Option as set forth in the Option
Agreement), exercise his or her Option to the extent

                                      -9-
<PAGE>

that Optionee was entitled to exercise it at the date of such termination. In
the absence of a specified time in the Option Agreement, the Option shall remain
exercisable for three (3) months following the Optionee's termination. If, on
the date of termination, the Optionee is not vested as to his or her entire
Option, the Shares covered by the unvested portion of the Option shall revert to
the Plan. If, after termination, the Optionee does not exercise his or her
Option within the time specified by the Administrator, the Option shall
terminate, and the Shares covered by such Option shall revert to the Plan.

          (c) Disability of Optionee.  If an Optionee ceases to be a Service
              ----------------------
Provider as a result of the Optionee's Disability, the Optionee may, but only
within twelve (12) months from the date of such termination (and in no event
later than the expiration date of the term of such Option as set forth in the
Option Agreement), exercise his or her Option to the extent that the Option is
vested on the date of termination.  If, on the date of termination, the Optionee
is not vested as to his or her entire Option, the Shares covered by the unvested
portion of the Option shall revert to the Plan.  If, after termination, the
Optionee does not exercise his or her Option within the time specified herein,
the Option shall terminate, and the Shares covered by such Option shall revert
to the Plan.

          (d) Death of Optionee.  If an Optionee dies while a Service Provider,
              -----------------
the Option may be exercised at any time within twelve (12) months following the
date of death (but in no event later than the expiration of the term of such
Option as set forth in the Notice of Grant), by the Optionee's estate or by a
person who acquires the right to exercise the Option by bequest or inheritance,
but only to the extent that the Option is vested on the date of death. If, at
the time of death, the Optionee is not vested as to his or her entire Option,
the Shares covered by the unvested portion of the Option shall immediately
revert to the Plan.  The Option may be exercised by the executor or
administrator of the Optionee's estate or, if none, by the person(s) entitled to
exercise the Option under the Optionee's will or the laws of descent or
distribution.  If the Option is not so exercised within the time specified
herein, the Option shall terminate, and the Shares covered by such Option shall
revert to the Plan.

          (e) Buyout Provisions.  The Administrator may at any time offer to buy
              -----------------
out for a payment in cash or Shares an Option previously granted based on such
terms and conditions as the Administrator shall establish and communicate to the
Optionee at the time that such offer is made.

     11.  Stock Purchase Rights.
          ---------------------

          (a) Rights to Purchase.  Stock Purchase Rights may be issued either
              ------------------
alone, in addition to, or in tandem with other awards granted under the Plan
and/or cash awards made outside of the Plan.  After the Administrator determines
that it will offer Stock Purchase Rights under the Plan, it shall advise the
offeree in writing or electronically, by means of a Notice of Grant, of the
terms, conditions and restrictions related to the offer, including the number of
Shares that the offeree shall be entitled to purchase, the price to be paid, and
the time within which the offeree must accept such offer.  The offer shall be
accepted by execution of a Restricted Stock Purchase Agreement in the form
determined by the Administrator.

                                      -10-
<PAGE>

          (b) Repurchase Option.  Unless the Administrator determines otherwise,
              -----------------
the Restricted Stock Purchase Agreement shall grant the Company a repurchase
option exercisable upon the voluntary or involuntary termination of the
purchaser's service with the Company for any reason (including death or
Disability).  The purchase price for Shares repurchased pursuant to the
Restricted Stock Purchase Agreement shall be the original price paid by the
purchaser and may be paid by cancellation of any indebtedness of the purchaser
to the Company.  The repurchase option shall lapse at a rate determined by the
Administrator.

          (c) Other Provisions.  The Restricted Stock Purchase Agreement shall
              ----------------
contain such other terms, provisions and conditions not inconsistent with the
Plan as may be determined by the Administrator in its sole discretion.

          (d) Rights as a Shareholder.  Once the Stock Purchase Right is
              -----------------------
exercised, the purchaser shall have the rights equivalent to those of a
shareholder, and shall be a shareholder when his or her purchase is entered upon
the records of the duly authorized transfer agent of the Company.  No adjustment
will be made for a dividend or other right for which the record date is prior to
the date the Stock Purchase Right is exercised, except as provided in Section 14
of the Plan.

     12.  Non-Transferability of Options and Stock Purchase Rights.  Unless
          --------------------------------------------------------
determined otherwise by the Administrator, an Option or Stock Purchase Right may
not be sold, pledged, assigned, hypothecated, transferred, or disposed of in any
manner other than by will or by the laws of descent or distribution and may be
exercised, during the lifetime of the Optionee, only by the Optionee.  If the
Administrator makes an Option or Stock Purchase Right transferable, such Option
or Stock Purchase Right shall contain such additional terms and conditions as
the Administrator deems appropriate.

     13.  Formula Option Grants to Outside Directors. Outside Directors shall be
          ------------------------------------------
granted Options in accordance with the following provisions:

          (a) All Options granted pursuant to this Section shall be Nonstatutory
Stock Options and, except as otherwise provided herein, shall be subject to the
other terms and conditions of the Plan.

          (b) Except as provided in subsection (d) below, each person who first
becomes an Outside Director on or after the IPO Effective Date, whether through
election by the stockholders of the Company or appointment by the Board to fill
a vacancy shall be automatically granted an Option to purchase up to 25,000
Shares (the "First Option") on the date he or she first becomes an Outside
Director; provided, however, that an Inside Director who ceases to be an Inside
Director but who remains a Director shall not receive a First Option.

          (c) Except as provided in subsection (d) below, each Outside Director
shall be automatically granted an Option to purchase up to 6,250 Shares (a
"Subsequent Option") following each annual meeting of the stockholders of the
Company occurring after the end of the Company's fiscal year 2000, if
immediately after such meeting, he or she shall continue to serve on the Board
and shall have served on the Board for at least the preceding six (6) months.

                                      -11-
<PAGE>

          (d)  Notwithstanding the provisions of subsections (b) and (c)
hereof, any exercise of an Option granted before the Company has obtained
stockholder approval of the Plan in accordance with Section 20 hereof shall be
conditioned upon obtaining such stockholder approval of the Plan in accordance
with Section 20 hereof.

          (e)  The terms of each First Option granted pursuant to this Section
shall be as follows:

               (i)    the term of the Option shall be ten (10) years.

               (ii)   the exercise price per Share shall be 100% of the Fair
Market Value per Share on the date of grant of the Option.

               (iii)  25% of the Shares subject to the Option shall vest twelve
months after the date of grant and 1/16 of the Shares subject to the Option
shall vest each quarter thereafter. provided that the Outside Director shall
continue to serve on the Board on such dates.

          (f)  The terms of each Subsequent Option granted pursuant to this
Section shall be as follows:

               (i)    the term of the Option shall be ten (10) years.

               (ii)   the exercise price per Share shall be 100% of the Fair
Market Value per Share on the date of grant of the Option.

               (iii)  the Option shall vest and become exercisable in full on
the fourth anniversary after the date of grant provided that in each case the
Outside Director shall continue to serve on the Board on such date.

     14.  Adjustments Upon Changes in Capitalization, Merger or Asset Sale.
          ----------------------------------------------------------------

          (a)  Changes in Capitalization.  Subject to any required action by the
               -------------------------
stockholders of the Company, the number of shares of Common Stock covered by
each outstanding Option or Stock Purchase Right, and the number of shares of
Common Stock which have been authorized for issuance under the Plan but as to
which no Options or Stock Purchase Rights have yet been granted or which have
been returned to the Plan upon cancellation or expiration of an Option or Stock
Purchase Right, as well as the price per share of Common Stock covered by each
such outstanding Option or Stock Purchase Right, shall be proportionately
adjusted for any increase or decrease in the number of issued shares of Common
Stock resulting from a stock split, reverse stock split, stock dividend,
combination or reclassification of the Common Stock, or any other increase or
decrease in the number of issued shares of Common Stock effected without receipt
of consideration by the Company.  The conversion of any convertible securities
of the Company shall not be deemed to have been "effected without receipt of
consideration."  Such adjustment shall be made by the Board, whose determination
in that respect shall be final, binding and conclusive.  Except as expressly
provided herein, no issuance by the Company of shares of stock of any class, or
securities

                                      -12-
<PAGE>

convertible into shares of stock of any class, shall affect, and no adjustment
by reason thereof shall be made with respect to, the number or price of shares
of Common Stock subject to an Option or Stock Purchase Right.

          (b) Dissolution or Liquidation.  In the event of the proposed
              --------------------------
dissolution or liquidation of the Company, the Administrator shall notify each
Optionee as soon as practicable prior to the effective date of such proposed
transaction.  The Administrator in its discretion may provide for an Optionee to
have the right to exercise his or her Option or Stock Purchase Right until
fifteen (15) days prior to such transaction as to all of the Optioned Stock
covered thereby, including Shares as to which the Option or Stock Purchase Right
would not otherwise be exercisable.  In addition, the Administrator may provide
that any Company repurchase option applicable to any Shares purchased upon
exercise of an Option or Stock Purchase Right shall lapse as to all such Shares,
provided the proposed dissolution or liquidation takes place at the time and in
the manner contemplated.  To the extent it has not been previously exercised, an
Option or Stock Purchase Right will terminate immediately prior to the
consummation of such proposed action.

          (c) Merger or Asset Sale. Subject to Section 15 below, in the event of
              --------------------
a merger of the Company with or into another corporation, or the sale of
substantially all of the assets of the Company (a "Merger"), each outstanding
Option and Stock Purchase Right shall be assumed or an equivalent option or
right substituted by the successor corporation or a Parent or Subsidiary of the
successor corporation (the "Successor Corporation").  In the event that the
Successor Corporation refuses to assume or substitute for the Option or Stock
Purchase Right, the Optionee shall fully vest in and have the right to exercise
the Option or Stock Purchase Right as to all of the Optioned Stock, including
Shares as to which it would not otherwise be vested or exercisable.  If an
Option or Stock Purchase Right becomes fully vested and exercisable in lieu of
assumption or substitution in the event of a Merger, the Administrator shall
notify the Optionee in writing or electronically that the Option or Stock
Purchase Right shall be fully vested and exercisable for a period of fifteen
(15) days from the date of such notice, and the Option or Stock Purchase Right
shall terminate upon the expiration of such period.  For the purposes of this
Section 14(c), the Option or Stock Purchase Right shall be considered assumed
if, following the Merger, the option or right confers the right to purchase or
receive, for each Share of Optioned Stock subject to the Option or Stock
Purchase Right immediately prior to the Merger, the consideration (whether
stock, cash, or other securities or property) received in the Merger by holders
of Common Stock for each Share held on the effective date of the transaction
(and if holders were offered a choice of consideration, the type of
consideration chosen by the holders of a majority of the outstanding Shares);
provided, however, that if such consideration received in the Merger is not
solely common stock of the Successor Corporation or its Parent, the
Administrator may, with the consent of the Successor Corporation, provide for
the consideration to be received upon the exercise of the Option or Stock
Purchase Right, for each Share of Optioned Stock subject to the Option or Stock
Purchase Right, to be solely common stock of the Successor Corporation or its
Parent equal in fair market value to the per share consideration received by
holders of Common Stock in the Merger.

     15.  Change of Control.  In the event of a Change of Control, each
          -----------------
outstanding Option held by an Outside Director shall vest and become exercisable
in full as to all of the Optioned Stock,

                                      -13-
<PAGE>

including Shares as to which the Outside Director would not otherwise be vested
or exercisable. If an Option becomes fully vested and exercisable as provided in
this paragraph, the Administrator shall notify the Optionee in writing or
electronically that the Option shall be fully vested and exercisable for a
period of fifteen (15) days from the date of such notice, and the Option shall
terminate upon the expiration of such period.

     16.  Date of Grant.  The date of grant of an Option or Stock Purchase Right
          -------------
shall be, for all purposes, the date on which the Administrator makes the
determination granting such Option or Stock Purchase Right, or such other later
date as is determined by the Administrator.  Notice of the determination shall
be provided to each Optionee within a reasonable time after the date of such
grant.

     17.  Amendment and Termination of the Plan.
          -------------------------------------

          (a) Amendment and Termination.  The Board may at any time amend,
              -------------------------
alter, suspend or terminate the Plan.

          (b) Shareholder Approval.  The Company shall obtain shareholder
              --------------------
approval of any Plan amendment to the extent necessary and desirable to comply
with Applicable Laws.

          (c) Effect of Amendment or Termination.  No amendment, alteration,
              ----------------------------------
suspension or termination of the Plan shall impair the rights of any Optionee,
unless mutually agreed otherwise between the Optionee and the Administrator,
which agreement must be in writing and signed by the Optionee and the Company.
