F3 · kind: On March 13, 2020, the reporting person acquired 2,150 shares of PRIM Common Stock, as reported on a Form 4 filed on March 16, 2020. That transaction was matchable under Section 16(b) of the Securities Exchange Act of 1934 with the reporting person's sale of PRIM Common Stock on December 17, 2019. The reporting person's broker reversed the March 13, 2020 transaction by the sale reported herein, and the reporting person has paid to PRIM $24,904.84, representing the full amount of the profit realized in connection with the short-swing transaction (as calculated under Section 16 standards). The average sale price for the December 17, 2019 transaction was erroneously reported in the reporting person's January 3, 2020 Form 4 as $23.13 per share due to a broker reporting error; it was $23.09 per share, with multiple transactions at prices ranging from $23.0676 to $23.1001 per share, inclusive.
