<p style="font-family:Times New Roman, Times, serif;font-size:10pt;margin:0pt;text-align:justify;text-indent:36pt;">On June 6, 2017, Milestone Scientific Inc. (the &ldquo;Company&rdquo;) entered into an agreement <font style="font-family:Times New Roman, Times, serif;font-size:10pt;">(the &ldquo;Agreement&rdquo;) in connection with the sale of its forty (40%) percent interest (the &ldquo;Shares&rdquo;) in Milestone China LTD (&ldquo;Milestone China&rdquo;) to an unaffiliated United States domiciled purchaser (the &ldquo;Purchaser&rdquo;). The purchase price for the Shares is $1.4 million (the &ldquo;Purchase Price&rdquo;), with $125,000 payable at closing and a non-interest bearing $1,275,000 promissory note (the &ldquo;Note&rdquo;) payable in quarterly installments of $125,000 until paid in full. The payment obligation of the Purchaser is secured by the Shares. The Note precludes the Purchaser from selling all or substantially all of its assets.</font></p>

<p style="font-family:Times New Roman, Times, serif;font-size:10pt;margin:0pt;text-align:justify;text-indent:36pt;">&nbsp;</p>

<p style="font-family:Times New Roman, Times, serif;font-size:10pt;margin:0pt;text-align:justify;text-indent:36pt;">In connection with the sale of the Shares, the Purchaser has granted the Company a ten (10) year option to repurchase the Share<font style="font-family:Times New Roman, Times, serif;font-size:10pt;">s for a price (i) during the initial two years equal to the Purchase Price, and (ii) thereafter at fair market value (the &ldquo;Option&rdquo;).</font></p>

<p style="font-family:Times New Roman, Times, serif;font-size:10pt;margin:0pt;text-align:justify;text-indent:36pt;">&nbsp;</p>

<p style="font-family:Times New Roman, Times, serif;font-size:10pt;margin:0pt;text-align:justify;text-indent:36pt;">The sale of the Shares allows the Company to continue to expand in the China market by suppl<font style="font-family:Times New Roman, Times, serif;font-size:10pt;">ying Milestone China with the Company&rsquo;s <i>STA Single Tooth Anesthesia System&reg;</i> and related hand pieces while eliminating the burden on the Company&#39;s management of an expanded role in the financial and business affairs of Milestone China. The Company believes that the sale will provide Milestone China with a new partner that may accelerate its penetration of the China market.</font></p>

<p style="font-family:Times New Roman, Times, serif;font-size:10pt;margin:0pt;text-align:justify;text-indent:36pt;">&nbsp;</p>

<p style="font-family:Times New Roman, Times, serif;font-size:10pt;margin:0pt;text-align:justify;text-indent:36pt;">The transaction will be accounted for as a secured financing. A Note Receivable will be presented on the Balance Sheet, along with a Deferred Gain on Disposition of Investment ($1,400,000). The carrying value of the forty (40%) percent investment at the transaction date was zero.</p>
