                                 DECEMBER 1999



1.   TransAmerican Energy Corporation's (the "Company") investment in TransTexas
     Gas Corporation ("TransTexas") and TransAmerican Refining Corporation

     value. The Company's investment in its subsidiaries is reflected in the
     Monthly Operating Report ("MOR") at cost.

2.   The secured note receivable from TransAmerican Refining Corporation was
     reflected in the Company's Schedules at its fully accreted balance of
     $920.0 million. The balance of this note receivable is reflected in the
     Company's MOR at its accreted balance as of April 20, 1999 and May 31, 1999
     of $899.2 million and $914.7 million, respectively. On June 15, 1999, this
     note receivable reached its fully accreted balance.

3.   During August 1999, the Company reversed the accrual of interest on the
     notes receivable from TransTexas and TARC in accordance with current
     accounting pronouncements applicable to companies operating under Chapter
     11.

4.   On June 15, 1999, the Company's senior secured discount notes reached their
     fully accreted balance of $1.13 billion.

5.   During August 1999, the Company reversed the accrual of interest and
     amortization of deferred debt issue costs related to its senior secured
     notes and senior secured discount notes in accordance with current
     accounting pronouncements applicable to companies operating under Chapter
     11.

6.   In December 1999, First Union National Bank ("First Union") disbursed $13.6
     million of funds held in trust for the benefit of TARC's subordinated
     noteholders to Firstar Bank, N.A. ("Firstar") for distribution to the
     holders of the Company's Senior Secured Notes, less reimbursement of
     reasonable fees and expenses, pursuant to a settlement agreement between
     First Union and Firstar dated December 2, 1999. This amount is reflected in
     the Company's December 1999 MOR as interest income from TARC with
     corresponding charges to interest expense on the Company's discount notes
     of $12.4 million and professional fees of $1.2 million.
