               event that title to the Building can be transferred before
               October 1, 2000, such date may be moved forward upon the written
               agreement of B.

          b.   In the event that B, or any third party designated by B to hold
               title in such party's name, borrows funds:

                         the land on which the Building shall be located [*] as
                         collateral, the parties shall apply in a single
                         application for the registration of title transfer for
                         the Building and the land on which the Building shall
                         be located, and the establishment and registration of
                         collateral rights for the bank loan.

Section 3: Construction Schedule

               documents required for the registration of the transfer of title
               of the Building. In the event that such official documents are
               incomplete or the procedure is not completed properly, so that
               the need arises for S to affix its seal to or procure additional
               official documents, S shall unconditionally cooperate in all
               respects, and may not take advantage of any such situation by
               rejecting a request for its cooperation or making any demands for
               compensation. Any

               violator of this clause shall be in breach of this Agreement and
               shall be liable to reimburse B for its losses.

          b.   When registration of the transfer of title takes place, the
               registration of such title transfer shall be in the name of B or
               any third party designee of B.

  2. In the event that B or the third-party registrant designated by B procures
     a bank loan:

          a.   Upon discussion between the parties, they may jointly authorize
               the firm of Land Registration Agent Lin Sheng-Yi (Land Scribe) to
               execute the registration of the Real Property. Related fees shall
               be borne by B.

          b.   The parties shall, within five (5) days following the completion
               by B of the procedures set forth in Section 2, Clauses 3, 4, 5, 6
               and 7, deliver to the Land Registration Agent (Land Scribe) the
               paperwork and official documents required for the registration of
               transfer of title, with their respective seals affixed thereto,
               for execution of the procedures for registration of the
               transferal of rights.

          c.   In the event that, due to the incompleteness of such official
               documents or the improper execution of such procedures, so that
               the need arises for S to affix its seal to or procure additional
               official documents, S shall unconditionally cooperate in all
               respects, and may not take advantage of any such situation by
               rejecting a request for its cooperation or making any demands for
               compensation. Any violator of this clause shall be in breach of
               this Agreement and shall be liable to reimburse B for its losses
               resulting from such violation.

          d.   Upon the execution of title transfer registration, title shall be
               registered in the name of B or such third party registrant that
               is designated by B. In the event that, for any reason
               attributable to B, it is not possible to cooperate with the Land
               Registration Agent (Land Scribe) and procure official documents
               required for the transfer of title, so that the tax payments or
               expenses of S are thereby increased, all such additional expenses
               shall be borne by B, except for the portions of such additional
               payments that are incurred before the delay and shall be payable
               by both parties.

Section 5: Liability for Warrantee of Title and Authorization
---------

  S hereby warrants that it possesses free and clear title to the Real Property,
  that the Real Property has not been previously sold to other buyers, and that
  that the Real Property does not encroach upon the land of any third parties.
  In the event that a third party alleges any rights or establishes additional
  rights or a lessee relationship, S shall assume responsibility for clearing
  title before B makes the final installment payment so that B may take title
  free and clear of any such claims.  In the event that B incurs any losses as a
  result of such third-party claims, S shall fully compensate B therefor.

Section 6: Assumption of Tax Payments
---------
<PAGE>

  1.  The parties hereby agree that payment of the building tax, utilities and
      other miscellaneous fees shall be borne by S before physical transfer of
      the Building, and shall be borne by B after physical transfer of the
      Building.

  2.  Payment of the registration fee for this transaction, the stamp tax, the
      deed tax (including notarization fees) and witness certification fees
      shall be borne by B. The land value increment tax and construction benefit
      fee shall be borne by S. Neither party may renege on its obligations
      hereunder, but in the event of an increase in the land value increment tax
      resulting from a delay caused by B, then B shall bear any resulting
      additional land value increment tax. (Land value increment tax paid
      pursuant to this Agreement shall be based upon the publicly announced fair
      market value of the Land applicable at such time.)

Section 7: Physical Transfer of Building
---------

  1.  The Building shall be transferred and taken possession of pursuant to a
      punch-list physical inspection. B shall, at the time of transfer of the
      building as notified by S, accept transfer and take possession after an
      on-site inspection.

  2.  Before the punch-list inspection and transfer of the Building, in the
      event of (a) occupation and use of the Building by a third party, (b) a
      natural disaster or major geological change, or (c) other majeure events
      resulting in damage or destruction, S shall assume responsibility for
      mitigation and restoration, and shall not cause B to bear any loss or
      liability, so that B takes the Building in a state of full completion.

Section 8: Liability for Breach
---------

  1.  In the event that either of the parties does not carry out its obligations
      pursuant to this Agreement, and fails to cure such breach within two (2)
      weeks after notification and request for cure from the non-breaching
      party, the non-breaching party may immediately terminate this Agreement.

  2.  Upon the execution of this Agreement, the parties may not renege on this
      Agreement or fail to execute their obligations hereunder; otherwise, such
      breaching party shall be found in breach of this Agreement and shall be
      dealt with accordingly.

  3.  In the event that B breaches this Agreement by refusing to purchase the
      Real Property or acts in any other way so as to breach this Agreement, S
      may, in addition to immediately terminating this Agreement, refuse to
      refund any and all payments made by B up to the time of the applicable
      breach. In the event that B makes any payment more than two (2) weeks
      after such payment is due, B shall pay S a late penalty after the
      expiration of such two-week cure period to be assessed in the amount of
      two hundredths of one percent (0.02%) of the Total Purchase Price per day.
      S may also terminate this Agreement, and may refuse to refund to B any and
      all payments made by B up to the time of such termination; provided,
      however, that in the event that title shall have already been transferred
      to B and the Real Property shall have been transferred to B for B's use, B
      shall unconditionally return the Real Property to S. B shall bear any
      related costs.
<PAGE>

  4.  In the event that S refuses to sell in violation of this Agreement, is
      unable to make any payment pursuant hereto, refuses to accept any payment
      made to it pursuant hereto, or commits any other act in breach of this
      Agreement, B may terminate this Agreement. In such event, S hereby agrees
      to immediately refund in full to B all payments made by B pursuant to this
      Agreement, and within five (5) days to return an amount to B equivalent to
      twice the amount of all payments made by B to S up to the time of such
      termination so as to compensate B for any losses due to the breach of this
      Agreement. The parties shall apply at the same time to cancel any title
      transfer that may be in progress at such time, and S shall bear any
      resultant taxes or fees.

  5.  In the event that S is unable to (a) complete the curtain wall of the
      Building within forty-five (45) days after the estimated completion date,
      (b) is unable to obtain a use permit within sixty (60) days after the
      estimated date for obtaining such use permit, or (c) is unable to execute
      the physical transfer of the Building within sixty (60) days of the
      estimated date for such physical transfer, each such estimated date being
      set forth in Section 3 of this Agreement, then S shall pay B a late
      penalty after the expiration of such relevant estimated date to be
      assessed in the amount of two hundredths of one percent (0.02%) of the
      Total Purchase Price per day. B may also terminate this Agreement, and
      following such termination S hereby agrees to immediately refund in full
      to B all payments made by B pursuant to this Agreement up to the date of
      such termination, plus interest calculated at an annual rate of eight
      percent (8%).

  6.  This Agreement shall become effective at the same time as the Real
      Property Building Sale and Purchase Agreement, and any failure to carry
      out obligations pursuant to one agreement shall be deemed a breach of both
      agreements.

  7.  S estimates that title to the Building will be transferred to B before
      October 15, 2000. In the event that S is unable to transfer title within
      sixty (60) days following such estimated date, then S shall pay B a late
      penalty after the expiration of such relevant estimated date to be
      assessed in the amount of two hundredths of one percent (0.02%) of the
      Total Purchase Price per day. B may also terminate this Agreement, and
      following such termination S hereby agrees to immediately refund in full
      to B all payments made by B pursuant to this Agreement up to the date of
      such termination, plus interest calculated at an annual rate of eight
      percent (8%).

  8.  In the event that B makes payment pursuant to this Agreement by sending
      wired funds, the date of payment shall be the date when B wires such
      funds, so that B shall be deemed to make payment in accordance with this
      Agreement if the date when such payment is wired is within the date
      specified herein. The date when S receives such wired funds shall not be
      deemed the date of payment of such funds.

Section 9: In regard to the rights and obligations related to the Building, B
---------
has already carefully read the Agreement over a period of seven (7) days and
agrees to act in accordance with the provisions of this Agreement.  In the event
that B transfers the rights and obligations pursuant to this Agreement to a
third party, B shall obtain the approval of S; provided, however, that such
approval shall not be required if B is acquired by or merges with a company
possessing comparable financial strength to that of B.

                       International Services Agreement

THIS INTERNATIONAL SERVICES AGREEMENT (the "Agreement") is entered into as of

Suite 1200, San Francisco, California 94105.

WHEREAS, Digital Island desires to transmit Internet traffic over iAsiaWorks'
telecommunications network in Asia, the Philippines and New Zealand (the

iAsiaWorks will provide to Client Internet Protocol ("IP")-capable services as
described in Attachment I, including its Exhibit A, attached hereto and
             ------------                ---------
incorporated herein by this reference (collectively, the "Services") to transmit
Client's Internet traffic over iAsiaWorks' backbone network (the "Network")
and/or other networks in the Territory with which iAsiaWorks maintains direct
connections from time to time. If necessary, the Network will support Client's
use of Border Gate Protocol routing to reach the Network.

2.     Clients' Obligations. iAsiaWorks' performance hereunder is conditioned
upon Client's performance of or compliance with the following:

2.1  Client shall provide Domain Name Server ("DNS") registrations and all DNS
name service functions for itself and its customers. Client shall give
iAsiaWorks reasonable prior written notice of (i) Client's need for additional
IP network numbers or (ii) changes in existing routing information.

2.2  At Client's sole expense, Client will connect its own computer hardware and
other telecommunications equipment (collectively, the "Equipment") directly to
the Network and, as between the parties hereto, shall be fully and solely
responsible for the Equipment and any damage thereto and the installation and
maintenance of full connectivity between the Equipment and the Network,
including the addition from time to time of any and all Equipment required to
support the then-current volume of Client's Internet traffic over the Network.
At Client's request, iAsiaWorks will assist Client in the maintenance and repair
of its Equipment for fees to be mutually agreed or as otherwise set forth in

---------    ------------
for any damage to the Equipment other than to the extent arising out of
iAsiaWorks gross negligence or misconduct.

2.3  The Client may only use the Services and/or access the Network for the
purposes expressly identified herein. Any other use or access is expressly
prohibited, including but not limited to any unlawful or illegal use by Client
in any jurisdiction where a transmission commences, transits or is terminated or

prorated payments and deposits returned to iAsiaWorks by any third party, if
any. In addition, on one party's material breach of this Agreement, the other

be obligated to remit the Termination Payment.

       On any termination of this Agreement, Client shall pay iAsiaWorks all

following provisions will survive termination, cancellation or expiration of
this Agreement: 2.3, 2.4, 2.4.1, 4.5, 6.2 through 6.5 and 7 through 9.

ORAL OR WRITTEN, WITH RESPECT TO THE NETWORK, THE OPERATION OR MAINTENANCE
THEREOF OR THE SERVICES PROVIDED HEREUNDER AT ANY TIME AND FROM TIME TO TIME,
iASIAWORKS DISCLAIMS (1) ANY WARRANTY OF MERCHANTABILITY OR FITNESS FOR A

(3) ANY WARRANTY THAT THE NETWORK WILL OPERATE WITHOUT INTERRUPTION.

       4.1.1  iASIAWORKS WILL NOT BE RESPONSIBLE OR LIABLE FOR ANY INDIRECT,
INCIDENTAL, SPECIAL OR CONSEQUENTIAL DAMAGES, INCLUDING, WITHOUT LIMITATION, (1)
THE LOSS OF PROFITS OR REVENUE (2) THE LOSS OF DATA OR INFORMATION, (3) THE COST
OF PROCUREMENT OF SUBSTITUTE SERVICES , AND (4) COSTS OR DAMAGES RESULTING FROM
DELAY, NON-DELIVERIES, MISDELIVERIES, SERVICE INTERRUPTIONS OR OTHER LOSS OF
ACCESS TO OR USE OF THE NETWORK, INCURRED BY EITHER PARTY OR ANY THIRD PARTY IN
CONNECTION WITH THIS AGREEMENT AND CLIENT'S USE OF AND ACCESS TO THE NETWORK,
WHETHER IN AN ACTION IN CONTRACT, TORT, BASED ON A WARRANTY OR OTHERWISE, EVEN
IF THE OTHER PARTY OR ANY OTHER PERSON HAS BEEN ADVISED OF THE POSSIBILITY OF
SUCH DAMAGES. IN NO EVENT SHALL iASIAWORKS' LIABILITY HEREUNDER EXCEED THE
AGGREGATE FEES PAID BY CLIENT HEREUNDER IN THE CALENDAR QUARTER IMMEDIATELY
PRECEDING THE DATE OF ANY CLAIM MADE BY CLIENT HEREUNDER.

       4.1.2  THE USE OF ANY INFORMATION OBTAINED VIA iASIAWORKS' NETWORK OR
SERVICES IS AND WILL BE AT THE SOLE RISK OF CLIENT AND ITS USERS AND OTHER
CUSTOMERS. CLIENT EXPRESSLY ACKNOWLEDGES AND AGREES THAT (I) IASIAWORKS

                                                                               2
<PAGE>

EXERCISES NO CONTROL WHATSOEVER OVER THE CONTENT, NATURE OR SCOPE OF THE
INFORMATION PASSING OVER ITS NETWORK AND (II) IASIAWORKS WILL NOT BE RESPONSIBLE
IN ANY WAY FOR THE ACCURACY, COMPLETENESS OR QUALITY OF INFORMATION OBTAINED
OVER THE NETWORK OR OTHERWISE THROUGH ITS SERVICES. CLIENT SHALL INDEMNIFY AND
DEFEND IASIANETWORKS AGAINST ANY CLAIMS BROUGHT AGAINST IASIAWORKS BY ANY OF
CLIENT'S USERS OR CUSTOMERS WITH RESPECT TO ANY INFORMATION OBTAINED OVER THE
NETWORK OR THROUGH THE SERVICES.

4.2  In addition to, and without limitation of, the indemnities set forth in
Sections 2.4.1, 2.5, 4.1.2 and 6.4.2 above, Client will indemnify, defend and
hold iAsiaWorks harmless from and against any and all claims, losses,
liabilities and actions to the extent arising out of (i) the Client's breach of
this Agreement, (ii) Client's business operations, including the provision of
Internet services to its own users and customers and the operation of a
telecommunications network, and (iii) any unlawful or illegal use of the Network
or related Services by Client's users or customers.

4.3  iAsiaWorks will defend, indemnify and hold Client and its directors,
officers, employees, agents and subcontractors harmless from and against any and
all third party suits, actions and proceedings, claims, liabilities, losses,
expenses (including reasonable attorney's fees), damages and costs (collectively

extent that (i) Client is obligated to indemnify iAsiaWorks from and against any
such Claim hereunder and/or (ii) such Claim arises out of Client's negligent or
intentional acts or omissions.

5.     Scheduled Interruptions in Service.
Although, as clearly set forth in Section 4 above, iAsiaWorks provides Client
with Services and use of and access to the Network on an "as is" basis without
warranty of any kind, iAsiaWorks will use reasonable commercial efforts to
maintain the Network in a manner that minimizes errors and interruptions in the
course of providing the Services. Client acknowledges that, in the ordinary
course of business, the Network or related Services may be temporarily
unavailable due to scheduled maintenance, either by iAsiaWorks or by a third
party provider or for any other reason. However, iAsiaWorks will use reasonable
commercial efforts to provide seven days prior written notice of any scheduled
Network or Services disruption. Should such a disruption arise out of the
failure of any equipment or services wholly or majority owned and operated by
iAsiaWorks and continue for more than 24 hours, Client may immediately terminate
this Agreement without any Termination Payment; provided that Client will remit
payment to iAsiaWorks for Services rendered through the termination date and
further provided that, on such a termination, iAsiaWorks will refund to Client
prorated payments and deposits returned to iAsiaWorks by any third party, if
any.

6.     Payments; Taxes.
6.1  iAsiaWorks shall assist Client in the connection of the Equipment to the
Network at the sites listed in Attachment I. Excluding amounts previously
                               ------------
remitted by Client to iAsiaWorks hereunder, applicable per-installation charges
will be payable upon completion of each installation. iAsiaWorks will invoice
Client for such charges within three business days after the completion of each
installation hereunder with payment due net 30 days thereafter.

6.2  Monthly Service fees (the "Service Fees") will be invoiced in advance on
the first of each month in which Services will be rendered, commencing in the
first month after an iAsiaWorks hub and functioning circuit have been connected
to the Equipment and are operational. If Client fails to notify iAsiaWorks
within three business days after installation that the connection is non-
operational, iAsiaWorks may commence invoicing for its Service Fees. The first
month of operation will be billed in arrears on a pro rata basis with the
                                                  --------
Service Fees therefor included in iAsiaWorks' invoice for the Service Fees for
the next month.

6.3  Payment of all Service Fees and, except as set forth above, other amounts,
if any, due hereunder, is due in U.S. dollars net 30 days after date of invoice,
payable via wire transfer or other mutually agreed upon method in accordance
with instructions provided by iAsiaWorks. iAsiaWorks may charge a late fee equal
to the lesser of 12% per annum or the maximum interest rate permitted by law on
undisputed amounts not paid when due for as long as such amount remains unpaid.
However, if Client disputes any invoiced amount in good faith, it must submit to
iAsiaWorks, within 45 days following the date of invoice (the "Challenge
Period"), full payment of the undisputed

                                                                               3
<PAGE>

portion of the invoice and written documentation identifying and substantiating
the disputed amount. Any amount not disputed in writing within the Challenge
Period will be deemed accepted for payment in full by Client.

6.4  Notwithstanding anything set forth above or in Attachment 1, Client
                                                    ------------
acknowledges and agrees that China Telecom or any successor entity and any third
party in the PRC or any successor entity (the "Third Party") through which
iAsiaWorks obtains access to telecommunications circuits in the People's
Republic of China ("PRC") require monthly deposits against future service.
Accordingly, within 10 business days of the Effective Date, Client will remit
the amount set forth in Attachment I (the "PRC Funds") in payment of the first
                        ------------
month's Services in the PRC and two separate one-month security deposits in the
amounts set forth therein. iAsiaWorks will promptly remit the PRC Funds to the
Third Party for disbursement as appropriate to China Telecom.*

     6.4.1  At such time as Client elects to terminate the services provided by
China Telecom for any reason Client will promptly notify iAsiaWorks in writing
and iAsiaWorks will take the actions necessary to terminate such services.
Following termination of the services, assuming that Client is current in the
payment of all Service Fees and in compliance with all rules and regulations
imposed by China Telecom, the Third Party or any other successor or replacement
entity, iAsiaWorks will refund to Client all PRC Funds, including any prorated
payments and deposits, returned to iAsiaWorks, if any, or, at Client's option,
apply those Funds to future Service Fees.

     6.4.2  Client acknowledges and agrees that, with respect to the payment of
the PRC Funds and the arranging for telecommunications services to be provided
in the PRC, iAsiaWorks is acting solely as Client's agent and will bear no
liability or responsibility for the PRC Funds (other than on iAsiaWorks'
misappropriation thereof), China Telecom's provision of telecommunications
services and circuits in the PRC, the repayment of each of the two separate
security deposits by the PRC and the Third Party, respectively, or any other
related matter. Client will indemnify and defend iAsiaWorks against any claims
arising out iAsiaWorks' acts or omissions on Client's behalf under this Section
6.4 and acknowledges that it is fully liable therefor.

6.5  All Service Fees and other amounts quoted to the Client herein are
exclusive of any federal, state, municipal or other governmental taxes, duties,
fees, tariffs or withholding obligations now or hereafter imposed on Client's
use of the Network and related Services. Such taxes, if any, other than taxes
assessed against iAsiaWorks' net income, will be invoiced separately by
iAsiaWorks and paid by Client or Client shall provide iAsiaWorks and/or the
appropriate authority with proof of exemption. If, in any international
jurisdiction, taxes must be withheld on any amounts to be paid by Client to
iAsiaWorks, the Client shall promptly notify iAsiaWorks, and, unless instructed
otherwise by iAsiaWorks, may deduct such taxes from the amount due and remit the
taxes to the appropriate authority.

7.     Assignment

Neither party may assign this Agreement or any of its rights or obligations
hereunder without the other party's prior written consent other than to an
affiliated entity or upon the merger, acquisition or sale of all or
substantially all the assets of the assigning party; provided that the assigning
party will promptly notify the other party of such an assignment and further
provided that provided that each and every assignee hereunder must agree in
writing to be bound by all the terms and conditions hereof.

8.     Confidential Information; Publicity.

Each party acknowledges that (i) all information relating to the business and
operations of the other party which it learns or has learned during or prior to
the term of this Agreement, including all operation data pertaining to the
Client's use of the access to the Network and the Services, including routing
data and outage information, (ii) the terms and conditions of this Agreement and
(iii) all information disclosed in or arising out of any dispute or arbitration
between the parties, including the outcome thereof, is and will be the valuable,
confidential and proprietary information of the disclosing party. The receiving
party will maintain all confidential information disclosed hereunder by the
disclosing party in confidence and will not disclose such information to any
third party other than those of its employees, contractors, agents or
representatives with a need to know such information; provided that each such
employee or contractor must have executed a confidentiality agreement or be
otherwise bound by the obligations of the receiving party hereunder. The
receiving party will safeguard the confidential information with the same degree
of care which it uses to protect its own confidential information.

                                                                               4
<PAGE>

This Section will not apply to any information which (i) is already lawfully in
the receiving party's possession (unless received pursuant to a nondisclosure
agreement); (ii) is or becomes generally available to the public through no
fault of the receiving party; (iii) is disclosed to the receiving party by a
third party who may transfer or disclose such information without restriction;
(iv) is required to be disclosed by the receiving party as a matter of law or
judicial or governmental order; provided that the receiving party will use all
reasonable efforts to provide the disclosing party with prior notice of such
disclosure so that the disclosing party may seek a protective order therefor;
and (v) is independently developed by the receiving party without any use of
confidential information. Each party acknowledges that any breach of this
Section by a receiving party will irreparably harm the disclosing party and on
any such breach, the disclosing party shall be entitled to promptly seek
injunctive relief in addition to any other remedies which it may have at law or
in equity.

Further to the foregoing, other than Client's right to identify iAsiaWorks to
Client's users and customers as an Internet service provider providing Services,
neither party shall publicize the existence of this Agreement without the other
party's prior written consent except as required by law. All press releases and
related marketing materials and other communications relating to this Agreement
or the Services provided hereunder shall be subject to the reasonable and timely
pre-approval of each party.

9.     General

9.1  Client and iAsiaWorks are entering into this Agreement as independent
parties and nothing herein shall be construed to create a partnership, joint
venture or agency relationship between the parties except as expressly set forth
in Section 6.4 with respect to matters concerning the PRC. Neither party will
have any authority to enter into agreements of any kind on behalf of the other
party or to bind or obligate the other party in any manner to any third party.

9.2  Notices required to be given pursuant to this Agreement shall be effective
when received, and shall be sufficient if given in writing, hand-delivered, sent
by telefax with confirmation of receipt, sent by First Class Mail, return
receipt requested (for all types of correspondence), postage prepaid, or sent by
overnight courier service and addressed as first set forth above.

9.3  This Agreement and the rights of the parties hereunder will be governed by
and interpreted in accordance with the laws of the State of California, without
reference to its conflict of law rules, and applicable federal law. The United
Nations Convention On Contracts For The International Sale Of Goods will not
govern or apply to this Agreement. All disputes arising out of or in connection
with this Agreement will be referred to and finally resolved by binding
arbitration in accordance with the rules of the International Chamber of
Commerce consistent with California and federal law. The arbitration proceedings
will be conducted in San Francisco, California in English before a three-person
panel knowledgeable about telecommunications, consisting of one arbitrator
selected by Client, one selected by iAsiaWorks and one arbitrator selected by
the other two arbitrators. The arbitrator may award any legal or equitable
remedy and may, in his discretion, require one party to pay the costs of the
arbitration as well as the fees and expenses, including reasonable attorneys'
fees, of the other party. In the absence of any such ruling, each party shall
bear its own costs in connection with an arbitration proceeding hereunder and
the parties shall share the costs of the arbitration equally.

9.4  Neither party shall be in default hereunder if its failure to perform any
of its obligations, excluding all payment obligations, is caused solely by
supervening conditions beyond that party's control, including acts of God, civil
commotion, strikes, labor disputes, third party telecommunications network
problems or down-time and governmental demands or requirements.

9.5  This Agreement including Attachment 1, (i) embodies the final, complete and
exclusive understanding between the parties, (ii) replaces and supercedes all
previous oral or written agreements, understandings or arrangements between the
parties, (iii) may be signed in counterparts, each of which shall be an original
and all of which shall constitute one and the same document and (d) may only be
amended in a writing signed by an authorized officer of each party hereto. The
failure of either party to enforce the provisions of this Agreement shall not be

                                                                               5
<PAGE>

deemed a waiver of such provisions or of the right of such party thereafter to
enforce such provisions or any other provisions hereof. If any provision of this
Agreement is held invalid or unenforceable by a court of competent jurisdiction,
the remaining provisions will remain in full force and effect and the parties
shall negotiate in good faith a substitute a valid and enforceable provision
which most nearly effects the parties' intent in entering into this Agreement

IN WITNESS WHEREOF, the parties have entered into this Agreement as of the
Effective Date.
