 Schedule II

 Borrower, Administrative Agent, and Lender Information 








 Schedule 4.7 
 Litigation 
 On February 9, 2012, Borrower and two of its officers, Gary A.
Kolstad and Ernesto Bautista III, were named as defendants in a purported class-action lawsuit filed in the United States District Court for the Southern District of New York (the “February SDNY Lawsuit”), brought on behalf of shareholders
who purchased Borrower’s Common Stock between October 27, 2011 and January 26, 2012 (the “Relevant Time Period”). On April 10, 2012, a second purported class-action lawsuit was filed against the same defendants in the
United States District Court for the Southern District of New York, brought on behalf of shareholders who purchased or sold CARBO Ceramics Inc. option contracts during the Relevant Time Period (the “April SDNY Lawsuit”, and collectively
with the February SDNY Lawsuit, the “Federal Securities Lawsuit”). In June 2012, the February SNDY Lawsuit and the April SDNY Lawsuit were consolidated, and will now proceed as one lawsuit. The Federal Securities Lawsuit alleges violations
of the federal securities laws arising from statements concerning Borrower’s business operations and business prospects that were made during the Relevant Time Period and requests unspecified damages and costs. In September 2012, Borrower and
Messrs. Kolstad and Bautista filed a motion to dismiss this lawsuit. The motion to dismiss was granted, and the Federal Securities Lawsuit was dismissed without prejudice in June 2013. 

On June 13, 2012, the Directors of Borrower and Mr. Bautista were named as defendants in a purported derivative action lawsuit
brought on behalf of Borrower by a stockholder in District Court in Harris County, Texas. This lawsuit alleges various breaches of fiduciary duty and other duties by the defendants that generally are related to the Federal Securities Lawsuit, as
well as a breach of duty by certain defendants in connection with stock sales. The lawsuit requests unspecified damages and costs, and has been further stayed while it is determined whether the plaintiffs in the Federal Securities Lawsuit will
appeal the dismissal or seek leave to file a second amended complaint.
