THIS AGREEMENT is made on February 26, 2004

BETWEEN:

(1)            DWEER TECHNOLOGY LTD., a Cayman Islands exempted company, the
               registered office of which is c/o Campbell Corporate Services
               Limited, 4th Floor, Scotiabank Building, P.O. Box 268GT, Grand

(2)            DESALCO LIMITED, a Cayman Islands company duly incorporated in
               the Cayman Islands, the registered office of which is Trafalgar
               Place, 1428A West Bay Road, Grand Cayman, Cayman Islands
               (hereinafter "DESALCO").

WHEREAS:

(A)            Pursuant to and upon the terms of a Distributorship Agreement
               dated 24 September 2002 between DWEER-Tech and DesalCo (the
               "DWEER-Tech Distributorship Agreement"), DWEER-Tech appointed
               DesalCo as its exclusive distributor for Products in the
               Territory (both terms as defined in the DWEER-Tech
               Distributorship Agreement) and gave DesalCo the exclusive right
               to sell and distribute the Products in the Territory.

(B)            Pursuant to and upon the terms of a Technology Licence relating
               to the manufacturing, marketing and sale of DWEER and LinX
               products, work exchangers and related products dated 30 April
               2003 ("the Technology Licence") between DWEER-Tech and Calder AG,
               a Swiss company, the registered office of which is
               Binzenholzstrasse 447, Industrie Nord, Ch-5704 Egliswil,
               Switzerland (hereinafter "Calder") DWEER-Tech granted Calder the
               exclusive right to, inter alia, design, manufacture and sell,
               inter alia, the Products worldwide, excluding the rights granted
               to DesalCo under the DWEER-Tech Distributorship Agreement which
               were reserved to DWEER-Tech.

(C)            By virtue of the fact that Calder has the exclusive right to
               manufacture the Products worldwide pursuant to the Technology
               Licence and will, during the term of the Technology Licence, be
               manufacturing and supplying Products on a worldwide basis, the
               parties hereto wish to suspend the DWEER-Tech Distributorship
               Agreement in order to allow Calder and DesalCo to enter into a
               new distribution agreement in the form of that attached at the
               Schedule hereto ("the Calder Distributorship Agreement"), in
               order to enable DesalCo to deal directly with Calder with respect
               to the

                                       1

               distribution of Products in the Territory so long as the
               Technology Licence is in effect.

(D)            Concurrent with the execution of this Agreement, the Technology
               Licence has been amended to remove the exclusion of rights
               mentioned in recital B above and so as to permit and enable
               Calder and DesalCo to enter into the Calder Distributorship
               Agreement.

(E)            Pursuant to this Agreement, the DWEER-Tech Distributorship
               Agreement is to be suspended for so long as the Technology
               Licence is in effect, on the basis that, inter alia, all clauses
               thereof that are intended to survive termination (e.g. 6.5 -
               Confidentiality) remain in effect, that DWEER-Tech undertakes to
               inform DesalCo of termination of the Technology Licence, and that
               the suspension is to be lifted immediately upon termination of
               the Technology Licence.

NOW IT IS HEREBY AGREED as follows:-

                  for so long as the Technology Licence remains in full force
                  and effect. In the event that the Technology Licence is

                  2.2.1    Neither party shall exercise any rights or perform
                           any obligations it has under the DWEER-Tech
                           Distributorship Agreement excepting only such rights
                           and obligations that have accrued or arisen prior to
                           the date of this Agreement; and

                  2.2.2    Notwithstanding the foregoing, the provisions of
                           clauses 6 and 10 of the DWEER-Tech Distributorship
                           Agreement shall continue to apply.

                           thereafter apply and continue in force and effect as
                           if this Agreement had not been entered into and

                                       3
<PAGE>

         2.4      In the event that the Technology Licence is terminated
                  DWEER-Tech shall give DesalCo notice in writing thereof within
                  14 days of such termination.

         2.5      DWEER-Tech hereby advises DesalCo that the Technology Licence
                  includes a provision that Calder may not amend, waive or vary
                  any of the provisions of the Calder Distributorship Agreement
                  without DWEER-Tech's prior written permission (which may be
                  given or withheld at its exclusive discretion). Any amendment
                  to the Calder Distributorship Agreement shall not in any way
                  be deemed to vary the DWEER Distributorship Agreement.

         2.6      DesalCo shall use its best endeavours to enable DWEER-Tech to
                  conduct testing and experimentation of Products on plants
                  owned or operated by DesalCo or its Affiliates at which
                  Products are installed provided that DWEER-Tech shall
                  indemnify and save harmless DesalCo from any costs, expenses,
                  loss or damage, of whatever type and howsoever caused arising
                  from or relating to such tests or experiments.

3.       TERMINATION

         The DWEER-Tech Distributorship Agreement shall terminate forthwith upon
         termination of the Calder Distributorship Agreement unless the latter
         is caused by the termination of the Technology Agreement, but, for the
         avoidance of doubt, such termination shall be without prejudice to any
         rights, remedies or obligations that have accrued or arisen under or
         pursuant to the DWEER-Tech Distributorship Agreement prior to
         termination thereof and any rights, remedies or obligations which are
         expressed or intended to continue after termination thereof. For the
         avoidance of doubt and notwithstanding the foregoing, in the event that
         the Technology Licence is terminated (following which the Calder
         Distributorship Agreement is terminated pursuant to clause 9.4
         thereof), the DWEER-Tech Distributorship Agreement shall revive in
         accordance with Clause 2.1 of this Agreement.

4.       MISCELLANEOUS PROVISIONS

         4.1      Nothing in this Agreement shall create or be deemed to create
                  a partnership or relationship of principal and agent or
                  employer and employee between the parties.

         4.2      This Agreement together with the DWEER-Tech Distributorship
                  Agreement contains the entire agreement between the parties
                  with respect to the subject

               right to sell and distribute the Products in the Territory.

(B)            Pursuant to and upon the terms of a Technology Licence relating
               to the manufacturing, marketing and sale of DWEER and LinX
               products, work exchangers and related products dated 30 April
               2003 between DWEER-Tech and Calder ("the Technology Licence")

               design, manufacture and sell, inter alia, the Products worldwide,
               excluding the rights granted to DesalCo under the Original
               Distributorship Agreement which were reserved to DWEER-Tech.

(C)            By virtue of the fact that Calder has the exclusive right to
               manufacture the Products worldwide pursuant to the Technology
               Licence and will, during the term of the Technology Licence, be
               manufacturing and supplying Products on a worldwide basis,
               DWEER-Tech and the parties hereto wish to suspend the Original
               Distributorship Agreement and enter into this Agreement, in order
               to enable DesalCo to deal directly with Calder with respect to
               the distribution of Products in the Territory so long as the
               Technology Licence is in effect.

               Licence has been amended to remove the exclusion of rights
               mentioned in recital B above and so as to permit and enable
               Calder and DesalCo to enter into this Agreement.

(E)            Concurrent with the execution of this Agreement, the Original
               Distributorship Agreement has been suspended for so long as the

               all clauses thereof that are intended to survive termination
               (e.g. 6.5 - Confidentiality) remain in effect, that DWEER-Tech
               undertakes to immediately inform DesalCo of termination of the
               Technology Licence, and that the suspension is to be lifted
               immediately upon termination of the Technology Licence.

                           pursuant to or in connection with this Agreement or
                           pursuant to or in connection with the Original
                           Distributorship Agreement, and the provisions of
                           clauses 5.4 5.5, 5.7 and 5.8 of this Agreement shall
                           also apply outside the Territory.

         2.5      Any energy-recovery devices (including pressure-exchangers or
                  work-exchangers) for water desalination using the reverse
                  osmosis process to be installed on reverse osmosis
                  desalination units with a brine flowrate of less than 880 US
                  gallons per minute (200 m3/hour) shall be deemed to be goods
                  which do not compete with the Products.

         2.6      DesalCo shall be entitled to describe itself as the
                  "authorised exclusive distributor" for the Products in the
                  Territory but it shall not hold itself out as DWEER-Tech's or
                  Calder's agent for sales of the Products or as being entitled
                  to bind DWEER-Tech or Calder in any way.

         2.7      DesalCo shall not without the express written permission of
                  Calder sell through a sales agent or to a sub-distributor any
                  Products which it purchases from Calder under this Agreement.

         2.8      Nothing in this Agreement shall entitle DesalCo to;

                  (a)      any priority of supply in relation to the Products as
                           against Calder's other distributors or customers;

                                       6

                  (b)      any right or remedy against Calder if any Product
                           supplied by Calder or its Affiliates is sold,
                           installed, or used in the Territory by any person
                           other than DesalCo or its Affiliates, provided that
                           Calder can show that it has obtained the written
                           undertaking required by sub-clause 2.2(c) above from
                           the person to whom Calder supplied the Product and
                           further provided that Calder shall, at the request
                           and expense of DesalCo, take all such steps as
                           DesalCo may reasonably require to assist DesalCo in
                           preventing the installation, use or resale of such
                           Products in the Territory.

         2.9      Calder shall not have any right or remedy against DesalCo if
                  any Product supplied by DesalCo or its Affiliates is sold,
                  installed or used outside the Territory by any person other
                  than DesalCo or its Affiliates, provided that DesalCo can show
                  that it has obtained the written undertaking required by
                  clause 2.3(e) above from the person to whom DesalCo supplied
                  the Product and further provided that DesalCo shall, at the
                  request and expense of Calder, take all such steps as Calder
                  may reasonably require to assist Calder in preventing the
                  installation, use or resale of such Products outside the
                  Territory.

3.       SUPPLY OF PRODUCTS

         3.1      Calder shall use its reasonable endeavours to supply the
                  Products to DesalCo in accordance with DesalCo's orders from
                  time to time and to deliver the same in accordance with
                  DesalCo's directions.

         3.2      Calder shall not be under any obligation to continue the
                  manufacture of all or any of the Products, and shall be
                  entitled to make such alterations to the specifications of the
                  Products as it may think fit from time to time and may, as it
                  thinks fit from time to time, change, amend or replace any
                  trademark used in relation to the Products (including, without
                  limitation, the Trade Marks).

         3.3      The prices for each order of Products to be supplied under
                  this Agreement shall be at least as good as and shall not be
                  more than the lowest price charged by Calder for comparable
                  orders of Products by other persons.

         3.4      Each order for Products by DesalCo shall be in writing and
                  shall constitute a separate contract and payment for such
                  Products shall be made by DesalCo without deduction or
                  set-off. The standard terms and conditions of sale of Calder
                  from time to time shall apply to all sales of the Products to
                  DesalCo under this

                                       7
<PAGE>

                  Agreement except to the extent that any of the same is
                  inconsistent with any of the provisions of this Agreement, in
                  which case the latter shall prevail, and subject to any
                  modifications thereto agreed to in writing between DesalCo and
                  Calder.

         3.5      Prior to acceptance of an order, DesalCo shall provide Calder
                  with comprehensive accurate drawings and plans showing the
                  manner in which Products will be incorporated into and
                  installed in the relevant desalination plant. DesalCo shall
                  give due regard to any observations or comments made by Calder
                  in relation thereto provided that Calder shall not thereby
                  incur any liability to DesalCo. Calder's observations and
                  comments shall be limited to compatibility of the Products
                  with the relevant desalination plant. Save as agreed in
                  writing by Calder, Calder shall not be liable or responsible
                  for the design, operation or functioning of any desalination
                  plants.

4.       MARKETING AND USE OF THE PRODUCTS

         4.1      DesalCo shall use its best endeavours to promote the sale and
                  use of the Products throughout the Territory and to satisfy
                  market demand therefor.

         4.2      DesalCo shall be entitled, subject to the terms of this
                  Agreement, to promote and market the Products in the Territory
                  in such manner as it may think fit, and in particular shall be
                  entitled to resell the Products to its customers on such terms
                  and at such prices as it may determine.

         4.3      DesalCo shall maintain such stocks of parts for the Products
                  as may be necessary to meet its customers' requirements.

         4.4      In connection with the promotion, marketing and the sale of
                  the Products, DesalCo shall:

                  (a)      make clear, in all dealings with its customers and
                           prospective customers, that it is acting as
                           distributor of the Products and not as agent of
                           Calder or DWEER-Tech;

                  (b)      comply with all legal requirements from time to time
                           in force relating to the storage and sale of the
                           Products;

                  (c)      use only such advertising, promotional, and selling
                           materials as are approved in writing by Calder;

                                       8
<PAGE>

                  (d)      provide an after sale service for customers in
                           relation to the Products on terms to be agreed from
                           time to time between DesalCo and Calder; and

                  (e)      advise Calder of projected sales of Products as early
                           as reasonably possible.

         4.5      Calder shall, from time to time, provide DesalCo with such
                  samples, catalogues, brochures, and up to date information
                  concerning the Products as Calder may consider reasonably
                  appropriate in connection with the sale of the Products in the
                  Territory, and Calder shall endeavour to answer as soon as
                  practicable any technical enquiries concerning the Products
                  which are made by DesalCo or its customers.

         4.6      DesalCo shall use its best endeavours to enable Calder to
                  conduct testing and experimentation of Products on plants
                  owned or operated by DesalCo or its Affiliates at which
                  Products are installed provided that Calder shall indemnify
                  and save harmless DesalCo from any costs, expenses, loss or
                  damage, of whatever type and howsoever caused arising from or
                  relating to such tests or experiments.

5.       INTELLECTUAL PROPERTY

         5.1      Calder hereby authorises DesalCo to use the Trade Marks in the
                  Territory on or in relation to the Products for the purposes
                  only of exercising its rights in performing its obligations
                  under this Agreement and Calder shall not so authorise any
                  other person, firm or company for such use provided that
                  Calder and/or DWEER-Tech may prohibit by notice in writing to
                  DesalCo any particular use of the Trade Marks which in the
                  opinion of Calder damages the goodwill of Calder or DWEER-Tech
                  in such Trade Marks.

         5.2      DesalCo shall ensure that each reference to and use of any of
                  the Trade Marks by DesalCo is in a manner, from time to time,
                  approved by Calder and, if requested, accompanied by an
                  acknowledgement, in a form approved by Calder, that the same
                  is a trade mark (or registered trade mark as the case may be)
                  of Calder or DWEER-Tech as the case may be.

         5.3      DesalCo shall not:

                  (a)      make any unauthorised modifications to the Products;

                                       9
<PAGE>

                  (b)      alter, remove, or tamper with any Trade Marks,
                           numbers or other means of identification used on or
                           in relation to the Products;

                  (c)      use any of the Trade Marks in any way that might
                           prejudice their distinctiveness or validity;

                  (d)      use in relation to the Products any trade marks other
                           than the Trade Marks without first obtaining the
                           prior written consent of Calder; or

                  (e)      use in the Territory any trade marks or trade names
                           so resembling any Trade Marks or the trade names of
                           DWEER-Tech or Calder as to be likely to cause
                           confusion or deception.

         5.4      Except as provided in clause 5.1, DesalCo shall have no rights
                  in relation to any of the Trade Marks or the goodwill
                  associated therewith, and DesalCo hereby acknowledges that,
                  except as expressly provided in this Agreement, it shall not
                  acquire any rights in respect thereof and that all such rights
                  and goodwill are, and shall remain, vested in DWEER-Tech or
                  Calder, as the case may be, and that all rights and benefits
                  arising from the use of the Trade Marks by DesalCo shall
                  accrue to and be for the benefit of Calder or DWEER-Tech as
                  the case may be.

         5.5      DesalCo shall, at the request and expense of Calder, take all
                  such reasonable steps as Calder may reasonably require to
                  assist Calder in maintaining the validity and enforceability
                  of any DWEER Intellectual Property during the term of this
                  Agreement.

         5.6      DesalCo shall, at the request and expense of Calder, execute
                  such agreements or licences in respect of the use of the Trade
                  Marks in the Territory as Calder may reasonably require,
                  provided that the provisions thereof shall not be more onerous
                  or restrictive than the provisions of this Agreement.

         5.7      DesalCo shall not, during the term of this Agreement,
                  challenge the validity of any DWEER Intellectual Property.

         5.8      DesalCo shall not do or authorise any third party to do any
                  act which would or might invalidate or be inconsistent with
                  any DWEER Intellectual Property and shall not omit or
                  authorise any third party to omit to do any act which, by its
                  omission, would have that effect or character.

                                       10
<PAGE>

         5.9      DesalCo shall promptly and fully notify Calder of any actual
                  threatened or suspected infringement in the Territory of any
                  DWEER Intellectual Property which comes to DesalCo's notice,
                  and of any claim by any third party so coming to its notice
                  that the importation of the Products into the Territory, or
                  their sale therein, infringes any rights of any other person,
                  and DesalCo shall at the request and expense of Calder do all
                  such things as may be reasonably required to assist Calder or
                  DWEER-Tech in taking or resisting any proceedings in relation
                  to any such infringement or claim.

6.       CONFIDENTIALITY

         6.1      Except as provided by clauses 6.3 and 6.4 below, DesalCo and
                  any Affiliate thereof shall at all times during the
                  continuance of this Agreement and thereafter:

                  (a)      use its best endeavours to keep all Restricted
                           Information (as defined below) confidential and
                           accordingly shall not disclose any Restricted
                           Information to any other person; and

                  (b)      not use any Restricted Information for any purpose
                           other than the performance of its obligations under
                           this Agreement or any other agreement for the sale of
                           the Products.

         6.2      "Restricted Information" means any information:

                  (a)      which is disclosed to DesalCo by Calder or DWEER-Tech
                           pursuant to or in connection with this Agreement or
                           the Original Distributorship Agreement or any other
                           agreement for the sale of the Products; (whether
                           orally or in writing); or

                  (b)      which relates to the Products and which comes into
                           the knowledge, possession or control of DesalCo
                           pursuant to this Agreement or the Original
                           Distributorship Agreement or any other agreement for
                           the sale of the Products;

                  regardless of whether or not such information is expressly
                  stated to be confidential or marked as such.

         6.3      Notwithstanding clauses 6.1 and 6.2 above, any Restricted
                  Information may be disclosed by DesalCo to:

                                       11
<PAGE>

                  (a)      any customers or prospective customers;

                  (b)      any governmental or other authority or regulatory
                           body;

                  (c)      any employees or Affiliates of DesalCo;

                  to the extent only as is required for the purposes
                  contemplated by this Agreement, or as is required by law and
                  subject in each case to DesalCo using its best endeavours to
                  ensure that the person in question keeps the same confidential
                  and does not use the same except for the purposes for which
                  the disclosure is made.

         6.4      Any Restricted Information may be used by DesalCo or its
                  Affiliates for any purpose, or disclosed by DesalCo to any
                  other person, to the extent only that it is, at the date
                  hereof, or hereafter, is or becomes public knowledge through
                  no fault of DesalCo or its Affiliates (provided that in doing
                  so DesalCo and its Affiliates shall not disclose any
                  Restricted Information which is not public knowledge).

         6.5      Any press releases, learned papers or similar publications
                  made by Calder that make reference to DesalCo or its
                  Affiliates or plants owned or operated by DesalCo or its
                  Affiliates shall be approved in advance by DesalCo provided
                  that such approval shall not be unreasonably withheld and
                  shall be given in a sufficiently timely manner.

7.       REPRESENTATIONS, WARRANTIES AND LIABILITY

         7.1      Subject as herein provided Calder warrants to DesalCo that:

                  (a)      all the Products supplied hereunder shall be of

                  DWEER-Tech and/or Calder shall not be liable to DesalCo by
                  reason of any representation or implied warranty, condition or
                  other term or any duty at common law, or under the express
                  terms of this Agreement, for any consequential loss or damage

                  Calder relating to the manufacture or supply of the Products,
                  their resale by DesalCo or their use by any customer.

                  (a)      It is a validly existing company in good standing
                           under the laws of its jurisdiction of incorporation
                           and is duly qualified as necessary to carry on its
                           business in the jurisdictions in which such business

                           delivered by it and is a valid and legally binding

                           terms.

8.       FORCE MAJEURE

         8.1      If either party's performance of this Agreement is affected by
                  Force Majeure (as defined below) it shall forthwith notify the
                  other party of the nature and extent thereof.

         8.2      Neither party shall be held to be in breach of this Agreement,
                  or otherwise be liable to the other, by reason of any delay in
                  its performance, or non performance, of any of its obligations
                  under this Agreement to the extent that such delay or non
                  performance is due to Force Majeure of which it is notified to
                  the other party, and the time for performance of such
                  obligations shall be extended accordingly.

         8.3      If the Force Majeure in question prevails for a continuous
                  period in excess of 180 days, the parties shall enter into
                  bona fide negotiations with a view to alleviating its effects,

                  reasonable, and if no agreement is reached between the parties
                  with respect thereto within 30 days, then either party may
                  upon giving written notice to the other, terminate this
                  Agreement without prejudice to any rights, remedies or
                  obligations which have accrued prior to termination.

         8.4      "Force Majeure" means, in relation to either party, any
                  circumstances beyond the reasonable control of that party

                  out, go slow, work to rule or other form of industrial action,

                  (a)      DesalCo fails to diligently promote the sale of and
                           the use of the Products throughout the Territory
                           provided that DesalCo does not have to offer to sell
                           or sell the Products to competitors that are bidding
                           in connection with the construction or expansion of
                           desalination projects in the Territory in connection
                           with which DesalCo or any of its Affiliates is also
                           bidding (but DesalCo may do so at its sole and
                           absolute discretion); or

                  (b)      DesalCo at any time challenges the validity of all of
                           any of the DWEER Intellectual Property;

                  provided that DesalCo fails to remedy the same within 30 days
                  after receipt of written notice giving full particulars of the
                  breach and requiring it to be remedied.

         9.3      DesalCo may, at any time, terminate this Agreement upon one
                  (1) month's prior written notice to Calder.

                  of the Technology Licence.

         9.5      Either party shall be entitled forthwith to terminate this
                  Agreement by written notice to the other (provided that such
                  termination shall not affect any orders accepted by and
                  binding on Calder as provided in clause 3.4 above) if:

                  (a)      that other party commits any material breach of any
                           of the provisions of this Agreement and, in the case
                           of a breach capable of remedy, fails to remedy the
                           same within 30 days after receipt of a written notice
                           giving full particulars of the breach and requiring
                           it to be remedied;

                  (b)      an encumbrancer takes possession or a receiver is
                           appointed over any of the property or assets of that
                           other party;

                  (c)      that other party makes any voluntary arrangement with
                           its creditors or goes into winding up or liquidation
                           (except for the purposes of amalgamation or
                           reconstruction and in such manner that the company
                           resulting therefrom effectively agrees to be bound by
                           or assume the obligations imposed on that other party
                           under this Agreement);

                  (d)      anything analogous to any of the foregoing under the
                           law of any jurisdiction occurs in relation to that
                           other party; or

                  (e)      that other party ceases, or threatens to cease, to
                           carry on business.

         9.6      For the purposes of clause 9.5 above, a breach shall be
                  considered capable of remedy if the party in breach can comply
                  with the provision in question in all respects other than as
                  to the time of performance (provided that time of performance
                  is not of the essence).

         9.7      Any waiver by either party of a breach of any provision of
                  this Agreement shall not be considered as a waiver of any
                  subsequent breach of the same or any other provision thereof.

         9.8      The rights to terminate this Agreement given by this clause 9
                  shall be without prejudice to any other right or remedy of
                  either party in respect of the breach concerned (if any) or
                  any other breach.

                  so long as is required and to the extent and insofar as is
                  necessary to allow DesalCo to complete any binding contracts
                  for the sale of the Products in effect at the date of
                  termination and any bids, offers, quotations and/or proposals
                  made by DesalCo to other persons prior to termination of this
                  Agreement which have been accepted before termination of this
                  Agreement or are capable of being accepted after termination
                  of this Agreement provided that, for the avoidance of doubt
                  and notwithstanding the foregoing, the provisions of clauses
                  2.1, 2.2 and 2.6 above shall cease to apply forthwith upon
                  termination of this Agreement;

         10.2     DesalCo shall cease to promote, market or advertise the
                  Products or to make any use of the Trade Marks other than for

                  Products and for such purpose only and to such extent the
                  provisions of this Agreement shall continue in full force and
                  effect;

         10.3     the provisions of clause 6, and any other clauses which are
                  intended to survive the termination of this Agreement, shall
                  continue in force in accordance with their respective terms
                  notwithstanding termination of this Agreement;

         10.4     DesalCo shall have no claim against Calder for compensation
                  for loss of distribution rights, loss of goodwill or any
                  similar loss;

         10.5     subject to as otherwise provided herein and to any rights,
                  remedies or obligations which have accrued prior to
                  termination, neither party shall have any further obligation
                  to the other under this Agreement.

11.      MISCELLANEOUS PROVISIONS

         11.3     Nothing in this Agreement shall create or be deemed to create
