March 11, 2019, Nanophase Technologies Corporation (the &ldquo;Company&rdquo;) and BASF Corporation (&ldquo;BASF&rdquo;) entered into
Amendment No. 4, effective as of January 1, 2019 (the &ldquo;Amendment&rdquo;), to the Zinc Oxide Supply Agreement originally dated
September 16, 1999 and subsequently amended during 2001, 2003 and 2012 (the &ldquo;Supply Agreement&rdquo;). The Amendment reduces
from $1,000,000 to $500,000 the amount of cash and cash equivalents (calculated in accordance with U.S. generally accepted accounting
practices (&ldquo;GAAP&rdquo;) that the Company must maintain to prevent a &ldquo;Triggering Event&rdquo; and consequent &ldquo;Technology
Transfer&rdquo; (as those terms as defined in the Supply Agreement) during a trailing 12-month period when the Company also reports
a net loss. The Amendment also provides that a Technology Transfer may be triggered if the Company&rsquo;s cash and cash equivalents,
using a broader, non-GAAP definition that includes the Company&rsquo;s aged receivables from BASF, zinc metal raw materials on
hand, and inventory of certain of the Company&rsquo;s zinc-based personal care ingredients, are less than $1,000,000. The Amendment
further changes certain requirements relating to the minimum inventory of certain zinc-based personal care ingredients that the
Company must maintain under the Supply Agreement.</FONT></P>
