CONFIDENTIAL TREATMENT REQUESTED


                      EXHIBIT A--GOVERNMENTAL ACTION CLAUSE

5.2 Buyer and Sellers recognize that the prices set forth in Paragraph 5.1 may
require adjustment, either increase or decrease, because of the imposition of
federal or state legislation or regulation after July 1, 1996, or any changes in
the interpretation and enforcement of existing federal or state requirements
after July 1, 1996, that impose or change a tax, assessment or other
governmental charge based on the volume of tons produced or the price of coal
sold by Sellers under this Agreement. In the event of such an imposition, either
party may submit to the other party detailed documentation of the proposed price
adjustment, and Sellers and Buyer shall meet to discuss and attempt to agree
upon an adjustment to reflect the actual change in Sellers' costs.

         In the event that Sellers elect to supply coal from sources other than
         Marrowbone, the provisions of this Paragraph 5.2 shall only apply to
         the price of coal from such sources if (i) Sellers purchase such coal
         for resale to Buyer under a contract with a term of at least one (1)
         year, and (ii) the contract between Sellers and the supplier of such
         coal provides for the payment by Sellers to the supplier of the types
         of costs described in this Paragraph 5.2, including any such costs in
         effect at the time Sellers execute a contract for the purchase of coal
         from such sources.

         In the event that Sellers elect to blend coal subject to price
         adjustments pursuant to this Paragraph 5.2 with other coals, only the
         price for the percentage of such coal supplied to Sellers that is
         subject to this Paragraph 5.2 shall be adjusted.

         In the event Sellers and Buyer are unable to agree as to the amount the
         price per ton should be increased or decreased, then the matter shall
         be submitted to an independent third party experienced in the matters
         in question that is acceptable to both Sellers and Buyer. The cost of
         such third party shall be borne equally by Buyer and Sellers. The price
         increase or decrease per ton, as determined by the independent third
         party, shall be binding on both Sellers and Buyer; provided, however,
         that any increase shall not exceed the amount previously proposed by
         Sellers, and any decrease shall not exceed the amount previously
         proposed by Buyer. In the event a third party cannot be agreed upon,
         the provisions of Paragraph 18.0, Third Party Selection shall apply.

18.0     Third Party Selection. In the event that the parties are unable to
         agree upon an independent third party to resolve matters referenced in
         Paragraphs 5.2, 7.4, and/or 8.3, the Center for Public Resources, New
         York, shall appoint an independent third party qualified in such
         matters to render a binding decision regarding any such disagreement
         pursuant to these three Paragraphs.
