          Appendix A, and Rotem undertakes to sell the Product as defined in the
          Specification enclosed herewith as Appendix A, at a total annual
          quantity per Agreement Year that shall not be less than the Minimum
          Quantity or more than the Maximum Quantity.

     3.2  The annual consumption quantity per Agreement Year shall be divided
          and delivered by Rotem to HCS in roughly equal parts over the twelve
          months of the respective Agreement Year.


4.   Quantities of Delivery and Purchase of the Product
     Annual Consumption Report

     4.1  Notwithstanding the provisions of this Agreement with regard to the
          HCS annual consumption quantities, the total annual consumption
          quantity of the Product by HCS from Rotem during the First Agreement
          Period (and only during the First Agreement Period) shall be 100,000
          tons

     4.2  Not later than 90 days prior to the beginning of each Agreement Year,
          except the First Agreement Period, HCS shall submit an Annual
          Consumption Report to Rotem, indicating the annual quantity of the
          Product within a range of +/- 10% that HCS intends to buy during the

          purchase quantity (hereinafter: the Arranged Quantity) shall not be
          less than the Minimum Quantity and shall not exceed the Maximum
          Quantity. Rotem undertakes hereby to provide the Arranged Quantity to
          HCS, and HCS hereby undertakes to buy the Arranged Quantity from
          Rotem, during each Agreement Year.
   5
     4.3  If it shall have become evident during the last quarter of a given
          Agreement Year that even if HCS shall withdraw the Maximum Quantity of
          the Product as allowed (pursuant to subclause 4.4 hereinbelow) for the
          same quarter, then subject to the other provisions hereof Rotem shall
          enable HCS during the last quarter of the same Agreement Year to
          withdraw an additional quantity of Product that shall complement the
          annual quantity of Product supplied by Rotem to HCS during the same
          Agreement Year to the Minimum Quantity (as defined in subclause 2.1
          hereinabove) (hereinafter: the Complementary Quantity); this even if
          as a result of the delivery of the Complementary Quantity by Rotem to
          HCS as aforesaid the quantity of consumption of Product by HCS during
          the same quarter shall exceed the allowed variation per quarter (as
          provided in subclause 4.4 hereinbelow), ON THE CONDITION THAT as a
          result of the consumption by HCS of the Complementary Quantity HCS
          shall not deviate by 40% from the portion obtained by dividing the
          adjusted annual quantity for the same Agreement Year (as stated in the
          Annual Consumption Report for the respective Agreement Year) by four
          (4), and also ON THE CONDITION THAT such deviation shall not in any
          case exceed 18,000 tons.

     Quarterly Consumption Report

     4.4  Without prejudice to the generality of the foregoing clauses 4.3 and
          4.4, not later than 45 days before the beginning of every calendar
          quarter, starting from the Second Agreement Year, HCS shall submit a
          Quarterly Consumption Report in writing to Rotem, notifying Rotem of
          the quarterly quantity of Product HCS desires to buy during the next
          calendar quarter, including the requested quantity for every month of
          the said quarter, on the condition that the total quantity of purchase
          for the said quarter shall not be by 20% more or less than the portion
          obtained by dividing the annual quantity by for the same Agreement
          Year (as stated in the Annual Consumption Report) for the same
          Agreement Year) by four (4), and on the condition that such increase
          or decrease shall be by a maximum of 9,000 tons, as the case may be.

     Purchases Beyond the Adjusted Quantity in the Annual Consumption Report

     4.5  Notwithstanding anything herein, Rotem shall be under no obligation to
          supply to HCS a quantity of Product in excess of the Adjusted Quantity
          stated in the Annual Consumption Report by HCS for the same Agreement
          Year; this even if such quantity is less than the Maximum Quantity.
          However, if with regard to any Agreement Year Rotem shall have agreed
          retroactively to allow HCS to buy from Rotem a total quantity of
          Product that exceeds the Adjusted Quantity stated by HCS in the Annual
          Consumption Report, then HCS shall be bound to pay Rotem for the total
          annual quantity of Product actually bought by HCS.
   6
     Noncompliance with the Purchase Quantities

     4.6  If it shall have become evident at the end of any Agreement Year that
          the quantity of Product actually bought by HCS from Rotem is less than
          the Adjusted Quantity indicated in the Annual Consumption Report
          and/or less than the Minimum Quantity, HCS shall pay to Rotem, on
          first demand in writing by Rotem and with Rotem being under no
          obligation to prove any incurred losses, the full price that HCS would
          have been bound to pay to Rotem under this Agreement for the
          outstanding balance of quantities of Product that would have been
          delivered to HCS in accordance with the Adjusted Quantity in the
          Annual Consumption Report with respect to the same Agreement Year if
          HCS were in compliance with its purchasing obligations with regard to
          the same Agreement Year.

     4.7  The foregoing subclause 4.7 shall apply also in case of any amendment
          of environmental laws. Without prejudice to the content of the
          foregoing subclause, however, if any change has to be made in the
          content of contaminants in the Product as a result of amendments of
          environmental laws, the parties shall discuss the prospects of
          altering the specification of the Product (Appendix A).


     Purchase of Product Beyond the Maximum Quantity
     4.8  Notwithstanding the content of the foregoing clause 4, in the event of
          HCS having requested during a given Agreement Year to buy an annual
          quantity of Product in excess of the Maximum Quantity as defined in
          the foregoing subclause 2.2 (hereinafter: the Surplus Quantity), Rotem
          shall have absolute and sole discretion as to whether to supply the
          Surplus Quantity to HCS, and if affirmative, at what price and on what
          terms.

     4.9  It is agreed and stipulated for the sake of clarity that no refusal by
          Rotem to deliver the Surplus Quantity as aforesaid shall be construed
          as breach of the contract, nor shall such refusal impair any of the
          obligations assumed by HCS under this Agreement and/or pursuant to any
          law.

5.   Transport and Unloading of the Product

          the transport of the Product from the Rotem plant at Zim to the Rotem
          plant at Oron, in a sum equal to the transport cost difference for HCS
          from Zin to Oron according to the transport tariffs payable by HCS to
          its carriers, shall be borne by HCS. Without prejudice to the
          foregoing, the expenses for transport of the Product from the Product
          Delivery Site to any other site or destination shall be under the sole
          responsibility of HCS and at the expense of HCS. The parties shall act
          in concert to cause that the main delivery site of the Product be at
          the Rotem plant at Zin, insofar as feasible.

     5.3  HCS shall submit the relevant freight differences of its carriers to
          Rotem in a regular and updated manner and/or on demand by Rotem,
          together with any changes in these tariffs.

6.   Product Quality

     6.1  Rotem undertakes that the Product quality shall be as stated in the
          specification enclosed herewith as Appendix A. Any change of the
          specification shall be subject to the written consent of Rotem and
          HCS.

     6.2  Any manipulation and/or change of the Product, of any kind whatsoever,
          regardless of whether for adjusting the Product to the needs of HCS or
          for any other purpose, shall be carried out at installations of HCS,
          under the sole responsibility of HCS and at the expense of HCS only.
          After the performance of such manipulation and/or change of the
          product, HCS shall not be entitled to make any claim whatsoever about
          unsuitability of the Product as delivered [in accordance with] the
          specification (Appendix A to this Agreement).

     6.3  The site of performance of the sample quality analyses of the Product
          and the manner and method of sampling, including the process and
          procedure of sampling and replacement of analyses, shall be as defined
          in the appendix entitled Quality Testing Analysis and enclosed
          herewith as Appendix C to this Agreement.

     6.4  No claim by HCS about the Product quality shall be considered unless
          submitted to Rotem in writing in a motivated form forthwith, and at
          any rate not later than seven days from receipt of the respective
          analysis by HCS.
   8
7.   The Price
     General
     7.1  It is agreed and declared between the parties that HCS shall pay the
          Product Price (as defined in the foregoing subclause 2.8) to Rotem for
          the quantity of Product delivered by Rotem to HCS during a given month
          of the Agreement Period (as defined in clause 10 hereinbelow), times
          the quantity of Product delivered to HCS during the same month.

     7.2  Within a maximum of 25 days from the end of each quarter, Rotem shall
          notify HCS in writing of the Product Price for quantities of Product
          to be delivered to HCS during the current quarter. Upon a written
          request by HCS and on the condition that such request is submitted to
          Rotem not more than once per Agreement Year, Rotem shall provide HCS
          with a certificate in writing by the certified public accountant of
          Rotem, certifying that the calculation of the Product Price for every
          quarter during the respective Agreement Year was done in a proper
          manner in accordance with the price formula given in subclause 2.8
          above.

8.   Terms of Payment
     8.1  The Product Price shall be determined by Rotem in US dollars and shall
          be payable by HCS in NIS at the representative exchange rate of the US
          dollar as of the time of the actual payment.

     8.2  The payment by HCS for the quantities of Product delivered (or
          scheduled to be delivered as provided in the foregoing subclause 4.6)
          by Rotem shall be based on the Product Price as determined by Rotem
          for the respective quarter, within a maximum of 30 days from the end
          of the calendar month during which the product is supplied by Rotem to
          HCS ("current plus 30").

     8.3  Money owed by one of the parties to the other party for any reason
          whatsoever shall not be offsettable.


9.   Weighing
     9.1  The consignments shall be weighed on scales installed at Rotem and
          scales installed at HCS. In the event of monthly deviations within
          0.5% (half of one percent) between the weighing at the Rotem scale and
          the weighing at the HCS scale, the reading obtained from the Rotem
          scale shall be binding on the parties.
   9
     9.2  If the monthly deviation referred to in the foregoing subclause 9.1
          exceeds 0.5%, the parties shall cooperate for testing the calibration
          of the scales by a method acceptable to both parties. If it becomes
          evident that the Rotem scale is not calibrated, the readings from the
          HCS scale shall be binding on the parties. If it becomes evident that
          the HCS scale is not calibrated, the readings from the Rotem scale
          shall be binding on the parties. If both scales are calibrated or of
          neither of them is calibrated, the mean value of the two readings
          shall be taken as the monthly quantity of Product supplied by Rotem to
          HCS, for the purposes of mutual accounting between the parties.

10.  Period of the Agreement
     10.1 This Agreement is made for a period starting on July 1, 1998, and it
          shall remain in force until December 31, 2001 (hereinafter: the Period
          of the Agreement). Upon a written request by one of the parties to the
          other party, the parties shall, during the last six months of the
          Period of the Agreement and without any obligation, examine the
          prospects for extending the Period of the Agreement (hereinafter: the
          Additional Period, or Additional Periods), which shall be regarded for
          all intents and purposes as part of the original Period of the
          Agreement; alternatively, the parties may execute a new agreement for
          the delivery of the Product.

     10.2 It is stipulated for the sake of clarity that nothing in the foregoing
          subclause 10.1 shall be construed as any undertaking by one of the
          parties to extend the Agreement or to enter into negotiation prior to
          and/or after the expiry of the Period of the Agreement for discussing
          an extension hereof.

11.  Breach
     11.1 The party that breaches this Agreement and/or any of the provisions
          hereof (hereinafter: the Breaching Party) shall compensate the other
          party (hereinafter: the Complying Party) for any damage and loss
          incurred by the Complying Party as a result of the breach hereof by
          the Breaching Party. This without prejudice to the rights of the
          Complying Party to seek and obtain any other relief available under
          law in addition to and/or in lieu of the payment of damages.

     11.2 It is stipulated for the sake of clarity that notwithstanding the
          provisions of the foregoing subclause 11.1, no party hereto shall be
          deemed to be in breach hereof if prevented from discharging its
          obligations hereunder by a force majeure as defined in clause 15
          below.
   10

     12.1 A party to this Agreement may terminate it forthwith by notice to the
          other party in one or more of the following cases:

          12.1.1 Issuance of a liquidation or receivership order, temporary or
                 permanent, against the other party hereto, unless the order is
                 rescinded within 120 days from issuance.

          12.1.2 Imposition of provisional or permanent attachment on the
                 majority of assets of the other party to this Agreement, unless

          this Agreement and Rotem may, at its sole discretion, without
          prejudice to any of its other rights hereunder or pursuant to any law
          and without placing itself in breach hereof, to discontinue the
          delivery of the Product to HCS forthwith on expiry of the Payment
          Deadline, or exercise any of its rights pursuant to any law for the
          fundamental breach hereof by HCS.

          After payment by HCS of the debt including arrears interest as
          stipulated in subclause 12.4 hereinbelow, Rotem shall resume the
          delivery of the Product in accordance with this Agreement on the
          condition that HCS shall have provided guarantees to the satisfaction
          of Rotem for the full payment of all subsequent moneys due to Rotem
          for future deliveries of the Product to HCS as provided in this
          Agreement.

     12.4 Any amount payable by one of the parties hereto to the other party
          hereunder and remaining in arrears shall bear arrears interest as

                 regular drawing account interest as applied at Bank Hapoalim BM
                 at the time;

          12.4.2 An arrears of payment by more than one week or a recurring
                 arrears in payment shall be charged with excess drawing account
                 interest as applied at Bank Hapoalim BM at the time.
   11
          It is stipulated for the sake of clarity that amounts in dispute
          between the parties, for whatever reason, shall be paid to Rotem at
          the times established herein, with the provision that any amount owed
          by Rotem to HCS after the settling of the dispute shall be repaid to
          HCS with interest as provided in the foregoing subclause 12.4, for the
          period from the actual payment to Rotem till the actual payment to
          HCS.

13.  Liability and Indemnification
     13.1 It is agreed that Rotem shall not be liable in any way toward any
          customers of HCS and/or toward other third parties of any kind.

     13.2 HCS undertakes to indemnify Rotem and keep it harmless in full,
          including fees for legal advice, forthwith on first demand by Rotem in
          writing upon the handing down of any court ruling, order, or other
          decision by a competent judicial or quasi-judicial authority,
          including an arbitrator, ordering Rotem to pay compensation or any
          other sum to customers of HCS and/or to any other third parties in
          connection with any demand and/or claim related to the Product
          contemplated herein, delivered or intended to be delivered by Rotem to
          HCS, including, inter alia, in connection with the quality or delivery
          of the Product or the time of its delivery. The foregoing provisions
          of this subclause shall apply on the condition that Rotem shall notify
          HCS without delay of any such claim and/or demand and shall assist HCS
          as reasonably requested for the defense against such claim and/or
          demand.

     13.3 Notwithstanding anything herein, it is agreed that Rotem shall not be
          liable for any indirect or constructive losses incurred by HCS and/or
          by any entity related to HCS; this even if it shall have been proven
          by or on behalf of HCS in the course of a legal process or in any
          other manner that Rotem shall have breached one or more of its
          undertakings hereunder.

     13.4 The liability of Rotem shall be limited as aforesaid to the amount of
          proceeds due to Rotem under this Agreement, with regard to the
          specific quantity of the Product subject to a demand for damages by
          HCS.

14.  Settling of Disputes
     14.1 Any disputes between the parties in connection with this Agreement,
          its implementation or interpretation, shall be resolved by arbitration
          to be held before a single arbitrator to be appointed by joint
          agreement between the parties.

     14.2 In the absence of agreement between the parties about the identity of
          the arbitrator within 14 days from written request by one of the
          parties to the other party about the identity of the arbitrator,
          either party may approach the President of the Israel Bar with a
          request that he appoint a single arbitrator for resolving the dispute.
   12
     14.3 The arbitrator shall be bound to hand down his award according to
          substantive law and to present grounds for his ruling; however, he
          shall be exempt from the obligation to proceed in accordance with the
          law of evidence and the rules of court procedure.

     14.4 The award shall be final and binding. The losing party shall pay the
          arbitration costs, including the fees of the arbitrator.

     15.1 The parties hereto shall be temporarily released from their
          obligations hereunder upon the occurrence of unforeseeable
          circumstances caused by a force majeure; this for the duration of such
          circumstances that preclude the discharge hereof by one of the
          parties. The term force majeure is defined for the present purposes as
          the occurrence of circumstances that are beyond the control of the
          party claiming force majeure, and shall have been unknown to the said
          party at the time of signing this Agreement and could not have been
          prevented by the said party by reasonable means - including natural
          disaster, war, fire, partial or total strike or lockout, and other
          events that are beyond the control of the party prevented from
          discharging its obligations as aforesaid and preclude the discharge of
          the obligations by such party for the duration of the said
          circumstances.

     15.2 On being prevented from discharging its obligations hereunder under
          the circumstances referred to in the foregoing subclause, the party
          shall notify the other party thereof without delay; the said party
          shall also notify the other party upon the lifting of the said
          circumstances.

     15.3 Subject to the provisions of subclauses 15.4 and 15.5 hereinbelow, the
          parties shall resume their discharge of this Agreement upon the
          lifting of the circumstances of force majeure.

     15.4 It is agreed and stipulated for the sake of clarity that the
          quantities of Product remaining undelivered during the period of force
          majeure shall be deducted from the Minimum Annual Quantity and Rotem
          shall be under no obligation to complete or deliver them; nor shall
          HCS be under any obligation to buy them after the end of the period of
          force majeure as aforesaid.

     15.5 In the event of the circumstances of force majeure lasting for a
          consecutive period of more than five months, each party hereto shall
          be entitled to terminate this Agreement forthwith by a written notice
          to the other party.

     15.6 It is agreed and stipulated for the sake of clarity that
          notwithstanding anything herein, cash shortage and/or financial
          difficulties of any kind, including cash flow difficulties, regardless
          of whether temporary or permanent, of either party, shall not be
          deemed to constitute force majeure.
   13
16.  Jurisdiction
     Subject to the provisions of the foregoing clause 14 hereof, the competent
     courts of law of Tel-Aviv-Jaffa shall have sole jurisdiction over any
     matter related to and/or arising from this Agreement.

17   Miscellaneous
     17.1 This Agreement voids any previous agreement made between the parties
          orally or in writing or through their demeanor.

     17.2 No waiver, extension or amendment whatsoever in this Agreement or in
          the Appendices hereto or in any part hereof shall be valid unless made
          in writing and signed by the parties, everything in accordance with
          the law. No delay in the exercise of the rights of any party hereto
          shall be deemed as waiver, and the said party shall be entitled to
          exercise all or any part of its rights hereunder or according to law
          at any time it deems fit.

     17.3 The parties declare that the undersigned persons are competent to sign
          on behalf of Rotem and HCS respectively.

     17.4 Notices sent by one of the parties to the other party shall be deemed
          to have reached their destination as follows: (a) 72 hours from the
          time of mailing by registered mail to the address indicated in the
          Preamble hereto, unless actually received before that; (b) forthwith
          if delivered in person at the address indicated in the Preamble hereto
          or if transmitted by fax to a number indicated in the preamble hereto
          (with certified receipt) not later than 16:00 hrs on a business day;
          if transmitted by fax after 16:00 hrs or on a nonbusiness day - the
          notice shall be deemed to have been received on the next business day.

               In witness thereof the parties have set their hand:

                             Appendix B - Logistics

1.   The Product shall be loaded on trucks and/or wagons from the Rotem loading
     facilities at Zafir - Zin and Oron.

2.   For the purpose of loading the Product at Zin only:
     2.1  HCS shall submit a daily notice in writing about the total quantity
          HCS wants to load with details on loading to Haifa and to HC South on
          wagons and trucks. The notice shall be transmitted by fax.

     2.2  HCS shall coordinate the arrival in a mutually arranged manner to the
          loading point of the wagons, and all the trucks shall be loaded within
          the same time interval on the same day.

3.   HCS shall hand over to the Rotem liaison persons a detailed weekly delivery
     plan in writing three weeks in advance, to fax No. 07 6564717.

4.   Loading of wagons on Sunday through Friday (and loading of trucks at Zin)

     week in advance.

5.   Loading of trucks not in accordance with the above shall only be allowed
     with the approval of the liaison persons at the loading site, in accordance
     with a special tariff, subject to prior coordination and without safety
     screening (the loading shall be done by means of a loader directly from the
     open storage heaps). Loading during the second or third shift shall be
     subject to the payment of a price supplement at the rate of $ 0.20 and $
     0.30 per ton respectively.

                          Appendix C - Quality Testing

1.   A sample shall be taken from every shipment by means of an automatic
     sampler installed on the silo.

2.   Daily Analysis
     2.1  The following parameters shall be determined:
               %   . . .           dry basis
               %  moisture
               %  CO(2)

     2.2  Submission of information by fax on the analysis:
          shipments until 11:30 hrs - on the same day till 16:00 hrs;
          shipments after 11:30 hrs - on the following day till 13:00 hrs.

     2.3  Sample of 500 gr shall be preserved for two weeks.

     daily analysis according to (2.1))
               %  C(2)O
               %  O. M.
               Granulometric distribution within the ranges of the 
               specification.

4.   Monthly analysis representative of the monthly quality
     4.1  A representative quantity shall be withdrawn from every daily sample
          for the preparation of a binding monthly sample for determining the
          quality of the delivered Product.

     4.2  The monthly analysis shall include all the elements of the
          specification (except arsenic and lead, which shall be tested for once
          in three months).

5.   The following rules shall apply in case of discrepancies between the
     results of analysis between the two companies:

     5.1       Discrepancy of up to
               %  ...           0.5 %
               %CaO             2.0 %
               % CO(2)          1.0 %
               Granulometric distribution - up to one standard deviation as 
               indicated in the specification
   17
          The results of the Rotem laboratory shall govern.

     5.2  With regard to discrepancies in excess of the foregoing ranges, the
          samples of each of the two companies for a decision on a repeated
          sampling shall be handed over to a neutral laboratory acceptable to
          both parties.

     5.3  The implementation of this clause is subject to a sampling method at
          HCS that is acceptable to Rotem. Alternatively, HCS shall carry out a
          periodic inspection of the testing and calibration procedures at the
          Rotem laboratory and the results of the latter laboratory shall be
          acceptable to HCS.

6.   In case of a substantial deviation from the specification, HCS shall be
     entitled to return the defective Product to Rotem on trucks. The freight
     for the returned Product in both ways shall be at the expense of Rotem.

     A substantial deviation from the specification means a deviation persisting
     for at least three consecutive delivery days with regard to critical items
     of the Product specification, so that even a corrective action by Rotem
     with regard to the regular shipments shall not have allowed compliance with
     the specification in terms of a monthly average.
