San Juan Basin Royalty Trust

Declares Monthly Cash Distribution

FORT WORTH, Texas, August 20, 2013 – Compass Bank, as Trustee of the San Juan Basin Royalty Trust (NYSE:SJT), today declared a monthly cash distribution to the holders of its Units of beneficial interest of $4,202,508.59 or $0.090166 per Unit, based principally upon production during the month of June 2013. The distribution is payable September 16, 2013, to Unit holders of record as of August 30, 2013.

Gas production for the properties from which the royalty was carved (the “Underlying Properties”) totaled approximately 2,887,968 Mcf (3,186,342 MMBtu). Dividing revenues by production volume yielded an average gas price for June 2013 of $3.72 per Mcf ($3.37 per MMBtu) as compared to $3.75 per Mcf ($3.42 per MMBtu) for May 2013. The average gas price may vary from the posted index price for the San Juan Basin. The index price is a gross sales price, and the revenues used in the calculation of average gas prices are net of transportation, processing and gathering costs. Furthermore, the distribution to the Trust in any given month may include significant volume adjustments for sales in prior months that reflect pricing for those prior months. Capital costs for the month were $757,031. Lease operating expenses were $3,391,942 and taxes were $1,171,547.
