WILLIAMS COAL SEAM GAS ROYALTY TRUST

PRESS RELEASE

Williams Coal Seam Gas Royalty Trust Announces Quarterly Cash Distribution

     DALLAS, TEXAS, August 4, 2006 — Bank of America, N.A., as trustee of Williams Coal Seam Gas Royalty Trust, today announced a quarterly cash distribution to the holders of its units of beneficial interest of $0.231941 per unit, payable August 29, 2006 to unitholders of record on August 14, 2006.

     The Trust owns net profits interests in certain proved coal seam gas properties owned by Williams Production Company (WPC) and located in the San Juan Basin of northwestern New Mexico (the “Working Interest Properties”) and southwestern Colorado, including WPC’s 35 percent net profits interest in 5,348 gross acres in La Plata County, Colorado (the “Farmout Properties”). The distribution per unit decreased from $0.266448 to $0.231941 primarily as a result of a decline in natural gas prices.

     WPC reported that production attributable to its gross interests in the properties burdened by the Trust’s net profits interests was 3.4 trillion British thermal units (TBtu) during the period associated with this quarterly cash distribution compared to 3.4 TBtu during the preceding period. When prior period adjustments are excluded, production in the current quarter was 3.4 TBtu compared to a similar 3.5 TBtu in the preceding quarter. The net contract price per MMBtu for this quarter was $2.24 per MMBtu as compared to $3.13 per MMBtu for previous quarter. WPC also reported approximately 379 infill wells have been drilled and of those, 351 wells are producing as of 6/30/2006, but are not yet in “pay” status to the Trust. This will occur after payout has been reached which should occur during the calendar year 2006.

     WPC has informed the Trust that it expects to reach a settlement with the MMS in 2006, regarding an audit issue covering time periods dating back to the inception of the Trust. Accordingly, distributions to the Trust will likely begin to be affected by withholding, as early as the fourth quarter 2006 distribution, an estimated $1.3 million recoupment on a quarterly basis in 2007 and continue until the Trust’s share (currently estimated to be under $5 million) has been recovered. (See 10-Q for the quarterly period ended March 31, 2006 — Contingencies).

     The Trust is a grantor trust formed by The Williams Companies, Inc., parent company of WPC, and was designed to provide unitholders with quarterly cash distributions and tax credits under Section 29 of the Internal Revenue Code, which has expired as of 12/31/2002, from certain coal seam gas properties. The units are listed on The New York Stock Exchange under the symbol “WTU”.
