                                   SETTLEMENT
                     AND TERMINATION OF SERVICES AGREEMENT

         THIS SETTLEMENT AND TERMINATION OF SERVICES AGREEMENT  ("Agreement") is
made between Exodus Communications,  Inc. ("Exodus"), a Delaware Corporation, on
the one hand, and Commtouch Software ("Company"), on the other

         This Agreement is made in reference to the following facts:

         As of January 9, 2002, Exodus contends that Company owes an outstanding
debt to Exodus in the  amount of  $491,442  as  payment  for  services  provided
through January 1, 2002 by Exodus to Company in accordance with the terms of the
Master Services Agreement,  Professional  Services  Agreement,  or Internet Data
Center Services  Agreement  between Exodus and Company dated March 25, 1998 (the
"Contract"); and

         Company  disputes  its  obligation  to pay the full  amount that Exodus
contends it is owed under the Contract; and

         WHEREAS,  it is now the desire and  intention  of Exodus and Company to
settle and resolve all disputes, differences and claims relating to the Contract
which exist between them as of the date of this Agreement, with the exception of
obligations arising out of this Agreement.

         NOW,  THEREFORE,  AND IN  CONSIDERATION  OF  THE  MUTUAL  PROMISES  AND
RELEASES CONTAINED HEREIN, THE PARTIES DO HEREBY AGREE AS FOLLOWS:

         1. Unless  otherwise  stated in Exhibit A, Company agrees to pay Exodus
the sum of $300,000 on or before January 10, 2002 or the payment shall be deemed
untimely. All payments are to be made by via wire transfer to:

Wells Fargo Bank, Palo Alto, CA
ABA 121000248
ACCT# 4950037887
In the name of Exodus Communications, Inc.

         2. In the event of any  failure to make a timely  payment,  as required
under  Paragraph  1 of this  Agreement,  Company  agrees  to pay the  amount  in
Paragraph 1 as well as any and all reasonable attorneys' fees and costs incurred
by Exodus in collecting such payment balance from Company.

         3. Except for the promises or  obligations  made or  undertaken in this
Agreement,  upon Exodus' receipt of the last payment  required under Paragraph 1
of this  Agreement,  Exodus  and  Company,  on  behalf of  themselves  and their
respective  successors  and  assigns,  each  hereby  releases  the other and its
current and former officers,  directors,  shareholders,  employees,  affiliates,
representatives,  and agents  from any and all  claims,  demands,  and causes of
action of any kind whatsoever,  whether or not now known,  suspected or claimed,
which either ever had, now has, or claims to have had relating or connected  to,
or arising out of, the Contract.  These mutual  releases apply and extend to all
rights, causes of action, or claims asserted, or which could have been asserted,
by either party to this Agreement as of the date of this Agreement, irrespective
of the theory of recovery that could have been asserted provided,  however, that
nothing herein shall be deemed to release  extracontractual  claims or claims or
causes of action the Debtors could bring under chapter 5 of the Bankruptcy Code.

<PAGE>
         4.  It is the  intention  of  Exodus  and  Company  in  executing  this
Agreement and in rendering and  receiving the  consideration  called for by this
Agreement  that  this  Agreement  shall be and is a full and  final  accord  and
satisfaction  and mutual general release of and from all matters relating to the
Contract.

         5. Exodus and  Company  each  acknowledges  that it is aware of Section
1542 of the Civil Code of the State of California, which provides as follows:

     A general  release does not extend to claims  which the creditor  does
     not know or  suspect  to exist in his favor at the time of   executing
     the release,  which if known by him must have materially  affected his
     settlement with the debtor.

Exodus and Company each waives and  relinquishes  any right or benefit  which it
has or may have under Section 1542 of the Civil Code of the State of California.
Exodus  and  Company  each  acknowledge  that they are aware  that they or their
attorneys  or agents may  hereafter  discover  claims or facts in addition to or
different from those which they now know or believe to exist with respect to the
subject  matter  of the  Contract.  Nonetheless,  it is their  intention  fully,
finally, and forever to settle and release all disputes and differences relating
to the Contract,  known or unknown,  suspected or unsuspected,  which now exist,
may  exist,  or  heretofore  have  existed  between  them,  except as  otherwise
expressly  provided in this  Agreement.  In furtherance of this  intention,  the
releases  herein given shall be and remain in effect as full and complete mutual
releases, except as otherwise expressly provided,  notwithstanding the discovery
or existence of any such additional or different claim or fact.

         6.  Any  person  signing  this  Agreement  for a party  represents  and
warrants that he has express authority to sign this Agreement for that party and
agrees to hold the opposing party harmless for any costs or  consequences of the
absence of actual authority to sign.

         7. This  Agreement is made under and will be governed by and  construed
in accordance with the laws of the State of California  (except that body of law
controlling conflicts of law). The language of this Agreement shall be construed
as a whole according to its fair meaning, and not strictly for or against one of
the parties.

         8.  Following  Exodus'  receipt of the payment in  Paragraph 1, Company
agrees to remove its equipment in accordance  with the Contract  within five (5)
business days of such payment and if not, Exodus is hereby  authorized to remove
the Company's  equipment from the Customer Area (as defined in the Contract) for
storage and charge the Company  storage  fees until the  Company's  equipment is
removed.  Exodus shall not be  responsible  for any data stored in the Company's
equipment. Company also agrees that upon execution of this Agreement, (i) Exodus
may enter the Customer Area and take  possession of any and all Exodus  Supplied
Equipment,  Rental Equipment or Exodus equipment in accordance with the Contract
( the "Exodus  Equipment");  (ii) that the Exodus Equipment does not contain any
material  owned by anyone other than Exodus;  and (iii) to the extent the Exodus
Equipment contains any material,  Company agrees to irrevocably assign to Exodus
any such  material.  Equipment  removal by Company  will be  accomplished  under
Exodus-supervised access and in accordance  with the terms of the  Contract.  If
Company  agrees to transfer to Exodus any of Company's  equipment as part of the
terms  of  this  Agreement,  Company  agrees  (i)  to  execute  a Bill  of  Sale
contemporaneously  with this Agreement with the appropriate details; (ii) remove
any material  owned by anyone  other than  Exodus;  and (iii) to the extent such
equipment contains any material,  Company agrees to irrevocably assign to Exodus
any such material.

<PAGE>
         9. If it has not already  done so, upon  execution  of this  Agreement,
Exodus will immediately cease providing all services  purchased by Company under
the Contract.

         10.  Company  agrees not to (i) through oral or written  statements  or
otherwise,  disparage or defame Exodus,  Exodus'  services or products;  or (ii)
take any action,  directly or indirectly,  that may cause damage to or otherwise
impair the business of Exodus or Exodus' current or future customers.

         11.  This  Agreement  may be  executed  in  counterparts  which,  taken
together,  shall constitute one and the same Agreement and shall be effective as
of the date last written below.

         12. The  parties  agree that this  Agreement  and its  specific  terms,
including the existence of this Agreement, will be held in strictest confidence,
and will not be disclosed to anyone  except the parties to it, their  respective
counsel and their necessary agents, any and all policing or regulatory  agencies
and as required by law.

         13. This Agreement  constitutes the entire agreement between Exodus and
Company with respect to the Contract and supersedes all prior  negotiations  and
agreements,  whether  written  or oral.  This  Agreement  may not be  altered or
amended except by an instrument in writing executed by both parties.

         14.  The  parties  understand  and agree that they are  represented  by
counsel of their choice,  and that they  have not relied upon the  statements or
advice of the other party, its agents, counsel or employees.

         IN WITNESS WHEREOF,  Exodus and Company have executed this Agreement on
the dates indicated below.

                                    ARTICLE 2

           REPRESENTATIONS AND WARRANTIES OF COMMTOUCH AND ACQUISITION

Commtouch  and  Acquisition  hereby  represent and warrant to each of Parent and
Merger Sub that:

         SECTION 2.1. Organization and Qualification.

         (a)  Acquisition  is a  wholly-owned  subsidiary of Commtouch and it is
held  free and  clear of all  Liens (as  defined  herein).  Acquisition  is duly
organized,  validly  existing  and  in  good  standing  under  the  laws  of the
jurisdiction  of  organization,  and it has all requisite power and authority to
own, lease and operate its assets or properties and to carry on their businesses
as now being  conducted  and is qualified to do business and is in good standing
as a foreign  corporation in each jurisdiction  where the ownership or operation
of  its  assets  or  properties  or  conduct  of  its  business   requires  such
qualification, except in the case where the failure to be in such good standing,
have such power and authority or  qualification is not, when taken together with
such other failures, reasonably likely to have a Material Adverse Effect.

         SECTION 2.2. Capitalization of the Acquisition.

         (a) The  authorized  share capital of the  Acquisition  consists of one
share, par value $0.01,  which was issued and held solely by Commtouch as of the
business day  immediately  preceding the date of this  Agreement.  Except as set
forth above,  there are no  preemptive  or other  outstanding  rights,  options,
warrants,  conversion  rights,  stock  appreciation  rights,  redemption rights,
repurchase rights, agreements, arrangements, calls, commitments or rights of any
kind that obligate  Acquisition  to issue or sell any shares of capital stock or
other securities of Acquisition or any securities or obligations  convertible or
exchangeable  into or exercisable for, or giving any person a right to subscribe
for or acquire, any securities of Acquisition or any of its subsidiaries, and no
securities  or  obligations  evidencing  such rights are  authorized,  issued or
outstanding.  Acquisition does not have any outstanding bonds, debentures, notes
or other obligations the holders of which have the right to vote (or convertible
into  or  exercisable  for  securities  having  the  right  to  vote)  with  the
shareholders of Acquisition on any matter.

         (b) All issued and outstanding Shares and securities of Acquisition are
duly authorized, validly issued, fully paid and non-assessable.

<PAGE>

         (c) Without  limiting the  generality  of the  foregoing,  the Board of
Directors of  Acquisition  has  unanimously  (i) approved this Agreement and the
transactions  contemplated  hereby,  and  (ii)  as of the  date  hereof  has not
withdrawn or modified such approval or resolution to recommend.

         SECTION 2.3. No Violations.

         Neither the  execution,  delivery and  performance of this Agreement by
Commtouch and Acquisition  nor the  consummation by Commtouch and Acquisition of
the transactions contemplated hereby or thereby will (i) conflict with or result
in any breach of any provision of the  respective  articles of  association  and
other  charter  documents  (or similar  governing  documents)  of Commtouch  and
Acquisition, (ii) to the best of Commtouch's and Acquisition's knowledge, result
in a violation or breach of or  constitute  (with or without due notice or lapse
of time or both) a default (or give rise to any right of termination, amendment,
cancellation  or  acceleration  or Lien) under any of the terms,  conditions  or
provisions of any note, bond, mortgage,  indenture,  lease,  license,  contract,
agreement or other instrument or obligation to which Commtouch or Acquisition is
a party or by which any of them or any of their respective  properties or assets
may be bound,  or (iii)  violate  any  order,  writ,  injunction,  decree,  law,
statute,  rule or regulation  applicable to Commtouch or  Acquisition  or any of
their respective properties or assets.

         SECTION 2.4. No Undisclosed Liabilities.

         Acquisition  has no material  indebtedness,  liabilities or obligations
(whether  known or unknown,  absolute,  accrued,  contingent  or  otherwise  and
whether due or to become due)  arising out of or relating to the  businesses  of
Acquisition, except for normal and recurring liabilities that have been incurred
by Acquisition in the ordinary course of business in offering and supporting the
Business,  including  its  obligations  under  an  intercompany  agreement  with
Commtouch  and certain  subsidiaries  thereof  ("Intercompany  Agreement"),  and
liabilities that, in the aggregate, are not reasonably likely to have a Material
Adverse Effect on Acquisition.

         SECTION 2.5. Contracts.

         Attached  hereto as  Exhibit A is a complete  copy of the  Intercompany
Agreement,  including  an  attachment  containing  contracts,   commitments  and
agreements  relating  to the  Business  that have been or shall be  assigned  by
Commtouch and certain of its  subsidiary  companies to  Acquisition  by no later
than the Effective  Time  (hereinafter  "Business  Agreements").  To the best of
Acquisition's knowledge,  there are no liens or other such encumbrances over its
rights in the Business Agreements, there are no conditions, beyond normal market
factors,  that might negatively  affect the renewal or ongoing  viability of the
Business  Agreements  and there are no pending  legal  actions by any party with
respect thereto.  Additionally,  except for such Business Agreements, the rights
and obligations to which Surviving Corporation shall assume within the framework
of this Merger,  Acquisition possesses no other agreements or commitments of any
kind that obligate it to any other liabilities or payments of any kind.

<PAGE>

         SECTION 2.6. ZapZone Network(R).

         Commtouch is the sole owner of all assets,  rights and  obligations  in
and of the  Business  unit known as ZapZone  Network/ZZN  and, by the  Effective
Time,  it will have  transferred  all of such  assets,  rights  and  obligations
thereto to Acquisition  by way of and as more fully defined in the  Intercompany
Agreement.

         SECTION 2.7. Litigation.

         Except as would not  reasonably be expected to have a Material  Adverse
Effect or to materially  delay or interfere with the consummation of the Merger,
there  is  no  civil,  criminal  or  administrative   suits,  claims,   actions,
grievances, arbitrations,  proceedings or investigations pending or, to the best
knowledge  of  Acquisition,   threatened  against  Acquisition  or  any  of  its
respective properties or assets.

         SECTION 2.8. Compliance with Applicable Law.

         Acquisition is in compliance  with the terms of all permits,  licenses,
variances,  exemptions, orders and approvals necessary for the lawful conduct of
the  Business of  Acquisition  (the  "Acquisition  Permits"),  except  where the
failure to hold such Acquisition Permits has not had and would not reasonably be
expected to have a Material Adverse Effect. The business of Acquisition has been
and is being conducted in compliance with all Applicable Laws,  except where the
failure to comply has not had and would not  reasonably  be  expected  to have a
Material Adverse Effect. To the best knowledge of Commtouch and Acquisition,  no
investigation or review by any  Governmental  Entity with respect to Acquisition
is pending or, to the best knowledge of Commtouch and Acquisition, threatened in
writing.

         SECTION 2.9. ZZN Intellectual Property and Software Licenses.

         (a) Definition. For purposes of this Agreement, "Intellectual Property"
means:  (A) the  ZapZone  Network  and ZZN  (together  "ZZN")  related  computer
software,  databases, works of authorship, mask works, technology, trade secrets
and other confidential information,  know-how,  proprietary processes, formulae,
algorithms,  models, user interfaces,  customer lists, inventions,  discoveries,
concepts,   ideas,   techniques,   methods,   source  codes,  object  codes  and
methodologies,  all as relating to ZZN only;  and (B) with respect to all of the
foregoing,  related  confidential  data  or  information  (collectively,  "Trade
Secrets").

         (b) Trade Secrets.  Commtouch and/or  Acquisition have taken reasonable
steps in accordance with normal industry practice to protect its Trade Secrets.

         (c) Ownership; Sufficiency of IP Assets. To Commtouch's best knowledge,

         obligations under the email service  agreements  described in Exhibit A
         ("Business Agreement(s)").  The Commtouch Group represents and declares
         that, to the best of its knowledge,  the Business Agreements  represent
         all of the consumer-class  email services  agreements that it possesses
         as  of  the  Effective  Date  hereof,   apart  from  select  agreements
         previously identified to Consumer Corp.

2.2      The  assignment  shall  be  effective  as of the  Effective  Date.  The
         preceding  notwithstanding,  the  Commtouch  Group  shall  continue  to
         provide the services  under said  agreements  until  December 31, 2001,
         23:59 pm Greenwich Mean Time ("Service  Termination Date"), at no extra
         charge. Upon the Service Termination Date, Consumer Corp, including any
         successor(s)  thereto,  shall be solely  responsible  for providing and
         maintaining the service, as required under each individual agreement of
         Exhibit A.

2.3      Consumer Corp agrees to make best efforts in providing and  maintaining
         the service to the customers under each such email service agreement at
         the  levels  required  by  the  applicable  service  level  commitments
         included in each agreement.

3.  ROYALTY PAYMENTS

3.1      As from the Effective Date until the Service Termination Date, Consumer
         Corp shall pay to CTLTD,  on behalf of the Commtouch  Group,  royalties
         equal to 100% of the cash revenues of any kind earned  and/or  received
         by Consumer Corp during said period.

3.2      As from the Service Termination Date, Consumer Corp shall pay to CTLTD,
         on behalf of the Commtouch Group, a royalty as follows:

------------------------------------------------------- -----------------------------------------------------
<S>                                                     <C>
January through March 2002                              70% of cash revenues described below
------------------------------------------------------- -----------------------------------------------------
April through June 2002                                 50% of cash revenues described below
------------------------------------------------------- -----------------------------------------------------
July through September 2002                             50% of cash revenues described below
------------------------------------------------------- -----------------------------------------------------
October through December 2002                           25% of cash revenues described below
------------------------------------------------------- -----------------------------------------------------
</TABLE>

         (a)      Consumer  Corp shall retain for its own use the first $200K of
                  royalty,  which would be otherwise payable to CTLTD,  provided
                  however that Consumer Corp shall retain not more than $150K of
                  royalty for the period January through March 2002.

3.3      The  royalty  shall be  calculated  on all cash  revenue  collected  by
         Consumer  Corp  from  any  Business  Agreement,  or  any  follow-on  or
         replacement   contract   executed   by   Consumer   Corp   relating  to
         consumer-class email services, including any form of outsource services
         or licensing of email software, and excluding revenue from Professional
         Services.   Advertising  revenue  generated  in  conjunction  with  the
         Business  Agreements shall be included after  subtracting any royalties
         or other payments due to third  parties.  The above  quarterly  periods
         reflect the periods during which revenues are earned for consumer-class
         email  services  provided  during  those  periods,  and the  fact  that
         payments are received in  subsequent  periods  shall not  prejudice the
         Commtouch  Group's  right to earn  royalties  for the prior  period(s).
         Payments from a customer  shall always be applied  initially to amounts
         outstanding under any period reflecting the highest  percentage revenue
         split to the  Commtouch  Group.  For purpose of  clarification,  should
         Consumer  Corp  transfer  or refer any  customer to any entity and such
         entity collects email related revenues from the customer, such revenues
         shall be included in the royalty schedule hereunder.

3.4      Royalty payments to Commtouch will be made monthly by Consumer Corp, in
         arrears in the month  following  each  calendar  month based on revenue
         collected in the preceding month.  Revenues  collected for the 12 month
         period after the Service  Termination  Date shall be  deposited  into a
         bank  lock-box  account in which  CTLTD and  Consumer  Corp will have a
         joint security interest. Transfers from this account will be based upon
         the royalty schedule included  hereinabove and will require  signatures
         from CTLTD and  Consumer  Corp.  For purposes of  clarification,  it is
         understood  and agreed that said account  will  continue to exist until
         the  amounts to be paid to CTLTD are  received  by it free and clear of
         all liens or other encumbrances.

3.5      Consumer Corp will ensure that all email related revenue collected,  as
         described above, is transferred by the customers of the  consumer-class
         email  services  or  Business  Agreements  directly  into the  lock-box
         account described above.

<PAGE>

3.6      Should any revenue be otherwise due under the Business  Agreements,  or
         follow-on or replacement contracts thereto, which is not collectable by
         reason of a failure  by  Consumer  Corp to provide  the  consumer-class
         email  services  in  accordance  with the  terms of the  Service  Level
         Agreements  contained  in  the  Business  Agreements  or  follow-on  or
         replacement  contracts  and remains  uncollected  for a period of sixty
         (60) days after it would normally be due, such revenue will be included
         for  purposes of  calculating  the royalty due to the  Commtouch  Group
         under Article 3.2 above (and the royalty shall be calculated  such that
         any  prior  quarterly  period(s)  outstanding  royalties  are  computed
         first). If such revenue is subsequently  collected it will not be taken
         into account in calculating future royalty payments.

3.7      If any  payments  from  customers  under the  Business  Agreements  for
         services  performed by the Commtouch  Group prior to the Effective Time
         are received into the lock-box account,  Consumer Corp will immediately
         release them to CTLTD.

3.8      Consumer Corp  represents and warrants that it will take all reasonable
         action, in a timely manner, to collect outstanding receivables from the
         relevant customers.

3.9      CTLTD agrees to transfer royalties received hereunder to the applicable
         Commtouch  entity  to the  extent  that such  entity  has  assigned  an
         agreement(s) on behalf of which the royalties have been earned.

4.  TRANSFERENCE OF ADDITIONAL MATERIALS

4.1      The Commtouch  Group shall provide to Consumer Corp all  agreements and
         related  customer   correspondence  relating  to  customers  that  have
         terminated  since June 30, 2001 and that are related to  consumer-class
         email  services,  and make available for copying by Consumer Corp other
         terminated  agreements that are reasonably  accessible to the Commtouch
         Group. For purposes of clarification,  those services provided directly
         to  enterprises  or  through  channel  partners  or  in  Japan  through
         Commtouch   KK  shall  not  be  included   within  the  scope  of  this
         sub-paragraph.

4.2      The  Commtouch   Group  shall  also  provide  i)  copies  of  available
         correspondence  that  relates  to the  transferred  agreements  and ii)
         copies of  available  correspondence  that  relate  to the  transferred
         agreements.

4.3      Furthermore,  the Commtouch Group shall make available to Consumer Corp
         copies of any reasonably available promotional  literature,  offerings,
         price lists,  etc. that might be reasonably useful to Consumer Corp. in
         the operation of the service.

5.  AUDIT RIGHTS

<PAGE>

Consumer  Corp agrees to prepare and maintain  complete  and accurate  books and
records  relating to its collection of fees relating to the Business  Agreement,
including follow-on or replacement  contracts thereto.  The Commtouch Group will
have the right to  personally  examine on a recurring  basis (once per  calendar
quarter), at the Commtouch Group's own expense, the relevant records of Consumer
Corp in order to verify  that the  Commtouch  Group  has been paid the  accurate
royalties,  as described  above. The Commtouch Group shall provide Consumer Corp
with advance  notice of its intention to audit.  The audit shall take place at a
time mutually agreeable but not later than fifteen (15) days following notice by
Commtouch Group. Consumer Corp shall provide all information that may reasonably
be required to  substantiate  the  royalty  calculation.  To the extent that the
audit reveals an  underpayment to the Commtouch Group of greater than five (5%),
in addition to paying such underpayment and any legal interest thereon, Consumer
Corp shall pay for the costs of the audit.

6.  LIMITATION ON CONTACT WITH FORMER CUSTOMERS

For a  period  of two (2)  years  as from  the  Service  Termination  Date,  the
Commtouch Group  undertakes not to offer any services that compete with Consumer
Corp's  consumer-class  email  services to be provided to any  customer  under a
Business Agreement.

7. ASSIGNMENT OF ZAPZONE NETWORK

As from the Effective Date, CTLTD hereby assigns to Consumer Corp all rights and
title in and to the goodwill and user accounts relating to its proprietary, free
consumer  email service known as ZAPZONE  NETWORK  ("ZZN").  Furthermore,  CTLTD
hereby  provides to Consumer Corp a  royalty-free,  perpetual,  non-transferable
(except to affiliated  companies) license to use the CTLTD software necessary in
running ZZN, and only for the purpose of running ZZN.

CTLTD  shall have the right to  designate  to  Consumer  Corp  during the twelve
months following the Effective Date, the name of a single, qualified third-party
with whom  Consumer  Corp will  negotiate  in good faith a  marketing  agreement
whereby the designated third party may offer domain registration  service to the
ZZN  customers.  The  agreement  shall be based upon  terms  that are  generally
reasonable in the industry  including  compensation to Consumer Corp but, in any
case,  will include an initial term not to exceed twelve  months,  an option for
renewal based upon mutual agreement,  the right for Consumer Corp to approve the
form and  substance  of any  promotion or offer and a  prohibition  on the third
party  from  offering  services  to ZZN  customers  which are in the  opinion of
Consumer Corp competitive with the Business.

8.  REFERRALS

<PAGE>

CTLTD or CTINC may refer  leads for  consumer-class  Email  Services to Consumer
Corp, and Consumer Corp may refer leads for  enterprise  email services to CTINC
or CTLTD.  For such referred  accounts,  the referring party will receive 15% of
the first six (6) months'  revenue  collected  from the referred  customer.  Any
Business Agreement which has terminated as of the Effective Date and provided by
CTLTD or CTINC  pursuant to Section 4 shall be treated as  referrals  under this
section and shall be subject  only to the royalty as set forth in this  Section.
In the event that one of the members of the Commtouch Group assigns and Consumer
Corp.  accepts an executed agreement that is not listed on Exhibit A to Consumer
Corp  subsequent  to the  Effective  Date,  Consumer  Corp  shall pay to CTLTD a
royalty  based on the  terms set forth in  Article 3 above,  with the  Quarterly
Period  commencing  with the first month during which  Consumer Corp earns a fee
under the agreement  and the royalty  obligation  lasting for the  equivalent of
four Quarterly Periods.

9.  BREACH

A party  shall  be  considered  in  breach  by the  other  party(ies)  if it has
materially failed to perform any material representation,  covenant, warranty or
term of this  Agreement  and said  failure is not cured by the  breaching  party
within  thirty  (30) days after  delivery to it of written  notice  thereof by a
non-breaching  party. Should said failure not be cured within the stated period,
the  non-breaching  party(ies)  shall have all rights  available at law. For the
failure to make any payment as and when due,  without  derogating from any other
rights of the non-breaching party(ies),  the breaching party shall be liable for
interest at the maximum lawful rate.
