in Exhibit B  the following shall apply with respect to all shared services 
or facilities and all services provided pursuant to this agreement:

          a)   Exhibit C  attached hereto sets forth facilities which remain 
to be completed.  National shall complete construction of the new VOC 
incinerator on the Fairchild Site as provided in Exhibit B.  To the extent 
that such facilities are now under construction or otherwise incomplete, 
National shall, at its sole cost and expense, complete the facilities in 
accordance with existing plans and specs in a good and workmanlike manner, as 
modified from time to time by agreement among the parties, so that such 
facilities will be operational and functional for the purposes intended.

          b)   A party obligated to perform a service or provide a product 
under this Agreement shall do so using standards of care consistent with and 
the high quality of performance historically experienced at the South 
Portland Facility, substantially as now being provided, and with such 
quantities as the other party may reasonably request.  All facilities to be 
operated by either party shall be operated and maintained in a manner 
consistent with the obligations of that party to perform hereunder.  Unless 
otherwise agreed, all costs and expenses of operating and maintaining a 
facility shall be paid by the 


                                       3





party owning that facility, subject to allocations as herein provided or as 
provided in the leases referred to in paragraph 3 hereof.

          c)   To the extent that (i) there are physical connections between 
the two sites such as for piping, wiring, conduits and the like or (ii) there 
is a physical flow from one site to the other of any substance such as water, 
electricity, gas, stormwater, groundwater, or the like, each party grants to 
the other an easement over, under and across its site for such purpose.  Such 
easements shall initially be located at the present location thereof but may 
be relocated by the party whose site is affected thereby at such party's sole 
cost and expense so long as such relocation does not interrupt or adversely 
affect the service provided to the other party through such easement. The 
easements required by this subparagraph are set forth in the Declaration of 
Reciprocal Easements between Fairchild and National dated of even date 
herewith, which Declaration of Easements shall control in the event of any 
inconsistencies with this subparagraph.

          d)   Except as otherwise specifically provided herein or in the 
Exhibits hereto, whenever a service or product is to be provided at a party's 
cost of providing such service or product, all direct costs of providing that 
service which standard cost accounting practices require to be included and 
all depreciation costs shall be included in determining the cost, and such 
costs shall be allocated to the recipient of the product or service based 
upon actual usage.  If the cost of providing the product or service to the 
recipient cannot be separately determined, then the total cost to the 
provider in supplying such product or service to itself and to the recipient 
shall be allocated between the provider and the recipient based upon relative 
usage between the two parties.  Overhead 


                                       4





not directly associated with a service or product shall not be included in 
the allocated costs.

from the plant to all Fairchild buildings that require nitrogen
or oxygen.  Nitrogen will be supplied from the existing nitrogen
plant (#14 on Exhibit A) until the new nitrogen plant (#24 on
Exhibit A) is completed and operating.  Both plants are located
on the Fairchild site.  Fairchild will grant appropriate access
easements with respect to operation and maintenance of the
nitrogen facilities.  Nitrogen and oxygen will be piped from the
nitrogen plant to Buildings 10, 12 and 18 on the National
premises.  Each party will be responsible for supplying its own
argon and hydrogen.  Each party agrees to use good faith
commercially reasonable efforts to cause BOC to enter into an
agreement among BOC, Fairchild and National promptly after the
execution of this Agreement in which BOC acknowledges that
Fairchild is the owner of the sites on which the BOC plants are
located and that Fairchild is a third party beneficiary of the
On-Site Product Supply Agreement between National and BOC dated
as of August 1, 1996 and acknowledges that such agreement shall
remain in full force and effect.

     2)   Cost Allocation.  Initially nitrogen and oxygen shall
be provided to the parties at the following formula for
allocating fixed and operating costs:


                                       11





                 System                        National/Fairchild
                 ------                        ------------------  
             Nitrogen/Oxygen                         55%/45%

             LN2 Tanks                               50%/50%

             Red. Volt. Starter                      50%/50%

             On-Site Support                         75%/25%

     Notwithstanding the foregoing, Fairchild's aggregate share of the 
foregoing costs shall not exceed $77,150 per month.

     Once National's usage of the nitrogen plant is such that, if the 
parties' costs were determined by separate metering, Fairchild's total 
monthly costs for three (3) consecutive months would be equal to or less than 
$77,150, then all of the foregoing costs for gas usage shall thereafter be 
allocated to the parties on the basis of actual usage of the gases as 
determined by metering each party's usage, with fixed, electrical and other 
related costs to be allocated in the same ratio.  The cost of installing 
meters for this purpose shall be shared equally by the parties.

     Costs of any nitrogen plant expansion and/or costs of using liquid 
nitrogen shall be allocated between the parties in the same ratio as the 
average allocation of nitrogen/oxygen costs to each party over the six months 
prior to such expansion (the "usage ratio"), unless the reason for the 
expansion is an increase in one party's manufacturing capacity.  In such 
event, the estimated additional nitrogen/oxygen usage resulting from such 
increased capacity shall be added to the expanding party's actual usage over 
the previous six (6) months in calculating the usage ratio.

     3)   Duration.  This service shall continue until terminated by mutual 
agreement of the parties.
