Acceptance of similar terms and conditions by GDCL as outlined above with respect to a credit facility extended to GDCL by the Bank's office in London, England, including a reduction in said facility to a maximum of (pound)2,500,000. 7. Payment of a risk premium of US $25,000 commencing April 1, 1997 and monthly thereafter.
