                  (or, at the option of the Purchaser, waived in writing) or if
                  the TCF/NAMF Agreement is validly rescinded in accordance with
                  the terms thereof by or on October

                  31, 2002, (or such later date as the parties may in writing
                  agree) this Agreement shall cease to have effect and each
                  party shall have no further claim under it against the other.

         4.3      If condition precedent (a) above is not fulfilled by or on

                  in writing) (1) the Purchaser may, provided the
                  non-fulfillment of such condition precedent is due to an act
                  or omission of the Vendors or TCP or NAMF and (2) the Vendors
                  may, provided the non-fulfillment of such condition precedent
                  is due to an act or omission of the Purchaser either:

                  (a)      defer Completion not more than 28 days after the due
                           date and the provisions of this clause 4.3, including

                  (b)      in the case of the Purchaser, waive condition
                           precedent (a) and pursue all remedies available to
                           it; or

                  (c)      in the case of the Vendors, proceed to Completion so
                           far as practicable (without prejudice to its rights
                           hereunder) and pursue all other remedies available to
                           it as if condition precedent (a) did not exist; or

                  (d)      rescind this Agreement in which case this Agreement
                           shall cease to have effect and each party shall have
                           no further claim under it against the other.

6.       WARRANTIES

         6.1      Subject to all matters or things disclosed in the Disclosure
                  Letter, the Vendors jointly and severally warrant to the
                  Purchaser that, as at the date hereof and, again, as at
                  Completion, the Warranties set out in Schedule 2 are true and
                  accurate in all respects.

         6.2      Each of the Warranties is without prejudice to any other
                  warranty or undertaking and, except where expressly stated, no
                  clause contained in this Agreement governs or limits the
                  extent or application of any other clause.

         6.3      The rights and remedies of the Purchaser in respect of any
                  breach of the Warranties pursuant to clause 6.1, clause 6.6 or
                  clause 6.8 shall not be affected by Completion, by any failure
                  to exercise or delay in exercising any right or remedy or by
                  any other event or matter whatsoever, except a specific and
                  duly authorised written waiver or release.

         6.4      The information in and incorporated in the Disclosure Letter
                  shall be deemed to be disclosed again at Completion.




                                       10

         6.5      The Vendors shall disclose in writing to the Purchaser any
                  matter or thing (other than those matters or things already
                  disclosed in the Disclosure Letter) which may to the knowledge
                  of the Vendors arise or, regardless of when they occurred,
                  become known to the Vendors after the date hereof and before
                  Completion which is inconsistent with any of the Warranties or
                  which might make any such Warranties inaccurate or misleading
                  at Completion.

         6.6      If the Vendors fail to disclose as required by clause 6.5, the
                  Purchaser's remedy shall be whatever remedies are available to
                  the Purchaser without limitation under this Agreement or
                  otherwise.

         6.7      In the event of any of such matters or things as are mentioned
                  in clause 6.5 above being disclosed to the Purchaser before
                  Completion then, if the aggregate effect of such matters or
                  things are such that the Business of the DesalCo Group is
                  materially and adversely affected, the Purchaser may, prior to
                  Completion, rescind this Agreement by notice in writing to the
                  Vendors. For the purposes of this clause 6.7, the Business of
                  the DesalCo Group shall be deemed to be materially and
                  adversely affected if the Purchaser, had it known of such
                  matters or things, might reasonably have been expected to
                  reduce the Purchase Price by US$2,360,000.00 (Two Million
                  Three Hundred and Sixty Thousand United States Dollars) or
                  more. Upon such rescission this Agreement shall cease to have
                  effect and each party shall have no further claim under it
                  against the other. Other than as provided for in this
                  Agreement, the Purchaser shall not be entitled to rescind this
                  Agreement.

         6.8      For the avoidance of doubt and notwithstanding the provisions
                  of clause 6.7 above, in the event of any such matters or
                  things as are mentioned in clause 6.5 being disclosed to the
                  Purchaser before Completion:

                  (i)      which do not give rise to the Purchaser's option of
                           recission pursuant to clause 6.7; or

                  (ii)     which do give rise to such option but the Purchaser
                           does not elect to exercise such option;

                  the Purchaser shall be entitled to claim damages for breach of
                  the terms of this Agreement.

         6.9      The Purchaser shall not be entitled to exercise its rights of
                  rescission under clause 6.7 without first giving the Vendors
                  seven days in which to remedy such matter or thing to the
                  reasonable satisfaction of the Purchaser and, if necessary,
                  the date set for Completion shall be deferred to such later
                  date (being no later than the later of (i) seven days from the
                  giving of notice by the Purchaser of his decision to rescind
                  and (ii) the date on which Completion would have taken place
                  had the right of rescission not arisen)





                                       11

                  as shall give the Vendors the opportunity to remedy the matter
                  or thing to the reasonable satisfaction of the Purchaser.

         6.10     The provisions of Schedule 4 shall operate to limit the
                  liability of the Vendors under and in respect of the
                  provisions of clauses 3.4 and 6 of this Agreement and the
                  Warranties set out in Schedule 2 of this Agreement; provided
                  that, such limitations shall in no way be exclusive
                  limitations and shall not prevent the Vendors or the Purchaser
                  from relying on any other provisions of this Agreement or any
                  legal principle with a view to limiting their liability
                  hereunder.

         6.11     The Purchaser hereby represents and warrants to the Vendors as
                  follows:

                  The Purchaser is a company duly organized, validly existing
                  and in good standing under the laws of the Cayman Islands. The
                  Purchaser has all requisite corporate power and authority to
                  enter into this Agreement, to perform its obligations
                  hereunder and thereunder and to consummate the transactions
                  contemplated hereby and thereby. All corporate acts and other
                  proceedings required to be taken by the Purchaser to authorize
                  the execution, delivery and performance of this Agreement and
                  the consummation of the transactions contemplated hereby have
                  been duly and properly taken. This Agreement has been duly
                  executed and delivered by the Purchaser and constitutes legal,
                  valid and binding obligations of the Purchaser, enforceable
                  against the Purchaser in accordance with its terms.

         6.12     The Purchaser acknowledges that it has not entered into this
                  Agreement in reliance upon any warranty, representation or
                  promise other than those set forth in this Agreement.

7.       RESTRICTIVE AGREEMENTS

         7.1      For the purpose of assuring to the Purchaser the full benefit
                  of the businesses and goodwill of the Company, each of the
                  Vendors undertakes by way of further consideration for the
                  obligations of the Purchaser under this Agreement as a
                  separate and independent agreement (which shall survive
                  Completion) that they will not, unless performing or required
                  under the Engineering Services Agreement or the DWEER
                  Distributorship Agreement, or acting as a director of the
                  Purchaser or otherwise with the consent of the Purchaser:

                           and, where the same is in his possession or control,
                           shall use his best endeavours to prevent the
                           publication or disclosure, without the prior written
                           consent of the Purchaser, such consent not to be
                           unreasonably withheld, of any information concerning
                           the business, accounts or finances of any Water
                           Supply Company or any of its clients' or




                                       12

                           customers' transactions or affairs, which may, or may
                           have, come to his knowledge;

                  7.1.2    for a period of seven years after Completion either
                           on his own account or for any other person directly
                           or indirectly endeavour to entice away from
                           employment with any Water Supply Company or the
                           Purchaser any person who to his knowledge is now or
                           has preceding the date of this Agreement been an
                           employee of any Water Supply Company or the Purchaser
                           save for Donna Stamper and Tina DeSilva whom the
                           Vendors may employ from a date no earlier than 6
                           months after Completion or such earlier date as the

         maintain the DWEER Transfer Agreement in full force and effect, and

         technology and fulfils its other obligations as set out therein. The
         Purchaser agrees that this Share Sale Agreement creates no relationship
         with DWEER-Tech and does not allow the Purchaser to make any claims
         against DWEER-Tech under this Share Sale Agreement.

         9.1      Subject to the terms of any confidentiality agreements binding
                  on the Purchaser, except as provided herein, and where
                  necessary for Completion by disclosing the minimum amount of
                  information necessary, no announcement of any kind shall be
                  made with respect to the subject matter of this Agreement
                  unless specifically agreed in writing between the parties.

                  without any prior notice or consultation with the Vendors,
                  make such announcements and disclosures as may be required
                  pursuant to the relevant laws, rules or regulations relating
                  to the listing or offering of the Purchaser's shares on the

                  Agreement and will not use, disclose or make available to any
                  other person any information which it or its advisers have

         9.3      This Agreement shall be binding upon each party's successors
                  and assigns and personal representatives (as the case may be)
                  but, none of the rights of the parties under this Agreement or
                  the Warranties may be assigned or transferred. Notwithstanding
                  the aforesaid, the Vendors agree that, if they are requested
                  to do so by the Purchaser, they will procure that the Company
                  take title, at the expense of the Purchaser, to the shares
                  held by NAMF in OCBVI pursuant to the terms of the TCF/NAMF
                  Agreement, provided that the Company shall not incur any
                  liability from doing so and, in so far as the Company does

                  liability for so long as the Company is owned by the Vendors.

                  expenses incurred by or on behalf of the parties, including
                  all fees of agents, representatives, solicitors, accountants
                  and actuaries employed by any of them in connection with the
                  negotiation, preparation or execution of this Agreement shall
                  be borne solely by the party who incurred the liability.

         9.5      Time shall be of the essence of this Agreement, both as
                  regards the dates and periods specifically mentioned and as to
                  any dates and periods which may by agreement in writing
                  between or on behalf of the Vendors and the Purchaser be
                  substituted for them.

                  be given hereunder shall be in writing and shall be served by
                  delivering the same by hand or by sending the same by
                  facsimile or reputable courier service and shall be deemed
                  given, if sent by hand, when delivered, if sent by facsimile,
                  upon the date stated in the transmission report or, if sent by

                  address as is notified by the relevant person from time to
                  time, provided that a notice given in accordance with the
                  above but received on a non-working day or after business
                  hours in the place of receipt shall only be deemed to be given

         9.7      If any of the provisions of this Agreement is found by any
                  Court or any other competent authority to be void or
                  unenforceable, that provision shall be deemed to be deleted
                  from this Agreement and the remaining provisions of this
                  Agreement shall continue in full force and effect.
                  Notwithstanding the foregoing, the parties shall thereupon
                  negotiate in good faith in order to agree the terms of a
                  mutually satisfactory provision to be substituted for the
                  provision so found to be void or unenforceable.

                  parties with respect to the subject matter hereof, supersedes
                  all previous agreements and understandings between the parties

                  instrument in writing signed by the duly authorised
                  representatives of the parties.

         9.9      Each party acknowledges that in entering into this Agreement
                  it does not do so on the basis of, and does not rely on, any
                  representation, warranty or other provision except as
                  expressly provided herein, and all conditions, warranties, or
                  other terms implied by statute or common law are hereby

                  counterparts and by the parties to it on separate
                  counterparts, each of which when so executed and delivered
                  shall be an original, but all the counterparts shall together
                  constitute one and the same instrument.

10.      GOVERNING LAW AND JURISDICTION

         10.1     This Agreement is governed by and shall be construed in
                  accordance with the laws of the Cayman Islands.

         10.2     The parties hereto agree that the Courts of the Cayman Islands
                  shall have the jurisdiction to settle any disputes that may
                  arise in connection with this Agreement and that any judgement
                  or order of a Cayman Islands Court in connection with this
                  Agreement is conclusive and binding on them and may be
                  enforced against them in the courts of any other jurisdiction.
                  This clause shall not limit the right of either party hereto
                  to bring proceedings




                                       15

                  against the other party in connection with this Agreement in
                  any other court of competent jurisdiction or concurrently in
                  more than one jurisdiction.

         10.3     The parties hereto waive any objection which they may have to
                  the courts of the Cayman Islands on the grounds of venue or
                  forum non-conveniens or any similar grounds as regards
                  proceedings in connection with this Agreement and they consent
                  to service of process by mail or by any other manner permitted
                  by the relevant law.

         10.4     Without prejudice of the rights of the Purchaser to employ any
                  method of service permitted by Cayman Islands Law, the Vendors
                  hereby irrevocably appoint Campbells, Attorneys-at-Law, as
                  their authorised agent for service of process in the Cayman
                  Islands. Any claim, form, writ, summons, judgement or other
                  notice of legal process shall be sufficiently served on the
                  Vendors if delivered to that agent at its address for the time
                  being. The Vendors shall not revoke the authority of that
                  agent. If for any reason that such agent no longer serves as
                  agent of the Vendors to receive service of process, the
                  Vendors shall promptly appoint another such agent and
                  immediately advise the Purchaser of that appointment.
