As a result of the transactions contemplated by the Merger Agreement, MCG was merged with and into PFLT Panama with MCG as the surviving corporation, following which MCG was merged with and into PFLT Funding II with PFLT Funding II as the surviving company.

Pursuant to the terms of the Merger Agreement, each outstanding share of MCG common stock (including shares of restricted stock) was converted into the right to receive (i) 0.32044 shares of PFLT common stock, resulting in the conversion to approximately 11,832,018 newly issued shares of PFLT common stock, subject to adjustment for fractional shares to be paid in cash, and (ii) $0.30595 per share in cash consideration.

PFLT Funding II, as the successor to MCG, intends to file with the SEC a certification on Form 15 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), requesting the deregistration of MCG’s common stock under Section 12(g) of the Exchange Act and suspension of MCG’s reporting obligations under Sections 13(a) and 15(d) of the Exchange Act.
