impact upon nuclei of substances  within defined  enclosures in said Secure Area
for observation of characteristic  photon,  gamma ray,  distributions  emanating
from said  neutron  nuclear  impact to yield a  definitive  photon  spectrum and
thereby determine a chemical composition of substances within said enclosures.

WHEREAS,  Lessor is willing to lease for a  temporary  period (not to exceed six
[6] months) a defined secure area (40' x 60') of the Del Mar Avionics Technology
parking area for a period not to exceed six (6) months to Lessee, said protected
