Note 10 — Commitments and Contingencies

We are named as a defendant in certain lawsuits and are a party to certain regulatory proceedings arising in the ordinary course of business. We do not expect that these matters, individually or in the aggregate, will have a material adverse effect on our financial condition.

In August 2013, Kimmeridge Energy Exploration Fund, L.P. (“Kimmeridge”) filed a lawsuit against Stone in the 15^th Judicial District Court in Lafayette Parish, Louisiana seeking damages in the amount of approximately $18.4 million plus interest, costs, and attorney fees. Kimmeridge alleges that (1) Stone was obligated by virtue of a letter of intent to negotiate in good faith and close an acquisition involving approximately 33,000 net mineral acres in the Illinois basin, and (2) Stone failed to pay brokerage costs incurred after December 31, 2012 pursuant to a separate letter of understanding between Stone and Kimmeridge. Stone denies Kimmeridge’s claims, as well as its damage calculations, and intends to vigorously defend against both claims. We cannot estimate the potential range of loss at this time.
