Pursuant to the Issuer's Articles of Incorporation (as amended, the Articles), effective as of 11:59pm, Eastern time, on the date set by resolution of the board of directors of EQT as the record date for distribution of shares of common stock of the Issuer (Common Stock) to holders of shares of EQT's common stock (such time, the Effective Time),
(2) the total number of shares of Common Stock issued and outstanding immediately prior to the Effective Time shall, automatically by operation of law and without any further action on the part of the Issuer or any holders of shares of capital stock of the Issuer, each be subdivided and converted into a number of shares of validly issued, fully paid and non-assessable shares of Common Stock authorized for issuance pursuant to the Articles equal to the quotient obtained by dividing (a) the product of (i) the number of shares of common stock of EQT, issued and outstanding as of the Effective Time, multiplied by (ii) the quotient obtained by dividing one (1) by eight hundred and one thousandths (0.801), multiplied by (iii) eight-tenths (0.80), by (b) one hundred (100).
