Spectra Systems Corporation

("Spectra Systems" or the "Company")

Exercise of Options

Spectra Systems announces that employees have recently exercised options over 36,000 shares of common stock of $0.01 each in the Company ("Shares"). The Shares are restricted securities as defined in Rule 144 of the US Securities Act of 1933 and have been or will be issued pursuant to an exemption from registration under Rule701 promulgated under the US Securities Act of 1933.

Accordingly the Company will apply for 36,000 Shares to be admitted to trading on AIM and it is anticipated that trading in such shares will commence on 23 November 2018 ("Admission").

Following Admission the Company's issued share capital will comprise:

573,690 shares in the Regulation S stock line ISIN number USU8457D1091 (AIM:SPSC); and

44,930,933 shares in the unrestricted line ISIN number US84756T1060 (AIM:SPSY).

Spectra Systems has no Shares in treasury, therefore 45,504,623 may be used by shareholders, from Admission, as the denominator for the calculations by which they will determine if they are required to notify their interest in, or a change in their interest in, the share capital of the Company under the FCA's Disclosure and Transparency Rules.
