percent (100%) of DuPont's requirements for the Services described
herein for its Mypolex(R) industrial diamond business.  

     (b)  Forecast and Monthly Quantity.  It is anticipated that
          -----------------------------
DuPont will require Services for the following number of Assemblies:

          Year          Number of Assemblies (per month)
          ----          --------------------------------
          [                              
                                         
                                         
                                        ]*

The foregoing forecast is not binding and is merely intended to
provide the parties with general guidance as to DuPont's demand for
Services.  On request by Contractor, DuPont shall provide Contractor
with an updated forecast of DuPont's anticipated demand for Services. 


     Contractor acknowledges that Services are typically provided for
[            ]* per day. Notwithstanding the above, Contractor shall
not be obligated to provide Services for more than [                ]*
per month.  In the event DuPont's production forecast changes, DuPont
shall inform Contractor as soon as reasonably possible of such change. 
The parties agree to cooperate with each other in order to reasonably
satisfy both parties' production needs.

     DuPont is developing a process wherein Contractor will be able to
explosively

                                        omitted text has been made
                                        with the Commission as part of
                                        Registrant's application for
                                        confidential treatment.

                                          ]*  In the event both
parties mutually determine to use [            ]* Contractor and
DuPont shall modify the operating instructions attached hereto as
Exhibit 1 accordingly.  For purposes of calculating the quantity of
Services provided per month, [                                         
                               ]*  In no event shall Contractor be
obligated to perform [           ]* if in the parties' reasonable
opinions such services would [                                         
                                   ]*  In the event the parties cannot
agree on whether [                                                     
              ]* at the request of either party, an independent
consultant shall be engaged to evaluate the impact of [                
                            ]*  The parties shall mutually select the
independent consultant.  Such consultant shall be skilled in the field
of mining and the integrity of subterranean mines.  The parties shall
share the cost of such independent consultant, whose determination
shall be final and binding upon the parties.

     (c)  Rolling Monthly Forecast and Production Order.  DuPont shall
          ---------------------------------------------
also provide Contractor with rolling monthly forecasts of production
requirements hereunder. The monthly forecast shall state DuPont's
anticipated demand for the next six (6) months.  To the extent
possible, DuPont shall specify in such monthly forecast the amount of
Services DuPont anticipates for [            ]* and development
activities.  It is understood that all such forecasts are estimates
only and are not commitments, provided, however, DuPont will submit
written confirmation of its production orders for Services hereunder
at least two (2) months in advance of the month in which the Services
are required (the "Production Order").  The Production Order
represents DuPont's binding commitment to procure Services from
Contractor, subject to the provisions of this Agreement.  

     DuPont shall deliver Assemblies to Contractor no later than the
last business day of the prior calendar month.  The number of
Assemblies delivered to Contractor shall be consistent with the
Production Order provided by DuPont to Contractor two (2) months
earlier.  Contractor shall arrange for the delivery of the appropriate
number of culverts from DuPont's supplier, as a release against
DuPont's master purchase order for the supply of culverts.  Contractor
shall furnish the Services with respect to such Assemblies by the last
day of the calendar month for which the Services were requested in the
Production Order.  In the unforeseen event that Contractor does not
complete such Services by the end of any calendar month, then
Contractor shall provide such Services every normal business day until
the month's Production Order of Product has been completed, and
Contractor shall make such Product available for immediate shipment. 
DuPont's Industrial Diamonds Business may, at its option, waive this
requirement upon written notice to


                                        *  Indicates portions of text
                                        that have been omitted.  A
                                        separate filing of such
                                        omitted text has been made
                                        with the Commission as part of
                                        Registrant's application for
                                        confidential treatment.

                                   5
Contractor.

     In the event the Services result in one or more blown shots (as
defined in Exhibit 2 attached hereto), Contractor shall not be
required to furnish additional Services with respect to the affected
Assembly.

     (d)  Penalty for Delivery of Fewer Assemblies than Specified in
          ----------------------------------------------------------
the Production Order.  The parties acknowledge that Contractor must
- --------------------
schedule time in the Dunbar Facility in order to provide Services to
DuPont.  Therefore, in the event DuPont provides Contractor with fewer
Assemblies than specified in the Production Order, DuPont shall
compensate Contractor as follows:

     (i)  If DuPont provides Contractor with no more than one Assembly
          less than specified in the Production Order, DuPont shall
          pay no compensation to Contractor, but Contractor shall not
          be responsible to DuPont for not completing the Services for
          the Assembly which was not provided.

     (ii) If (for any reason including force majeure) DuPont provides
          Contractor with more than one Assembly less than specified
          in the Production Order (and further provided that
          Contractor is substantially in compliance with the terms and
          conditions of this Agreement and the Sublease (as defined in
          Paragraph 7 below), DuPont shall pay Contractor the Service
          Fee [                                                        
                                                                       
                                  ]* for each Assembly less than
          specified in the Production Order.

Contractor may, at its option, provide Services for more Assemblies
than specified in the Production Order, provided that such excess
Services shall be applied to current or subsequent quarterly take or
pay requirements, and may, at DuPont's option, be applied towards the
subsequent periods' Purchase Order requirements, .  Contractor may, at
its option, waive the penalty specified in this Paragraph.

     (e)  DuPont shall have the obligation to take or pay for
Assemblies as further set forth in Exhibit 2 attached hereto.

                                        omitted text has been made
                                        with the Commission as part of
                                        Registrant's application for
                                        confidential treatment.

     accordance with [                                                 
                                                                       
                                    ]*

     (b)  a raw material fee in the amount of Contractor's reasonable
     cost of the Explosive and other raw materials directly related to
     the Services (as set forth in Exhibit 1) provided on each
     Assembly (the "Raw Material Fee").

provided, however, that DuPont shall not be required to pay Contractor
for Services which result in an Assembly where the bottom end of the
Assembly does not remain intact ("blown shot").

     In 1996, DuPont shall take or pay Services for [                  
            ]*.  In 1997 and thereafter, DuPont shall take or pay
Services for [                                      ]*

     In the event DuPont is required to pay a penalty to Contractor
pursuant to Paragraph 5(d) of this Agreement, DuPont shall not be
required to pay Contractor twice for failure to take such Services. 
As such, if failure to take Services is subject to fees under both
Paragraph 5(d) and this Exhibit, only one such fee shall be paid to
Contractor, in order that duplication of fees be avoided.
