         TransAmerican Energy Corporation, a Delaware corporation (the
"Company"), hereby offers (the "Exchange Offer"), upon the terms and subject to
the conditions set forth in this Prospectus and the accompanying Letter of
Transmittal (the "Letter of Transmittal"), to exchange (i) up to an aggregate
principal amount of $475,000,000 of its 11 1/2% Series B Senior Secured Notes
due 2002 (the "Senior Secured Exchange Notes") for an equal principal amount of
its 11 1/2% Senior Secured Notes due 2002 (the "Outstanding Senior Secured
Notes" and, together with the Senior Secured Exchange Notes, the "Senior
Secured Notes") and (ii) up to an aggregate principal amount of $1,130,000,000
(as shown on the face thereof) of its 13% Series B Senior Secured Discount
Notes due 2002 (the "Senior Secured Discount Exchange Notes" and, together with
the Senior Secured Exchange Notes, the "Exchange Notes") for an equal principal
amount (as shown on the face thereof) of its outstanding 13% Senior Secured
Discount Notes due 2002 (the "Outstanding Senior Secured Discount Notes,"
together with the Outstanding Senior Secured Notes, the "Outstanding Notes"
and, collectively with the Exchange Notes, the "Notes"), in integral multiples
of $1,000.  The Exchange Notes will be senior secured obligations of the
Company and are substantially identical (including principal amount, interest
rate, maturity and redemption rights) to the Outstanding Notes for which they
may be exchanged pursuant to this Exchange Offer, except for certain transfer
restrictions and registration rights relating to the Outstanding Notes and
except for certain interest provisions relating to such rights.  The
Outstanding Notes have been, and the Exchange Notes will be, issued under an
Indenture dated as of June 13, 1997 (the "Indenture" or "TEC Notes Indenture"),
among the Company and Firstar Bank of Minnesota, N.A., as trustee (the
"Trustee").  See "Description of the Exchange Notes." There will be no proceeds
to the Company from this offering; however, pursuant to a Registration Rights
Agreement dated as of June 5, 1997 (the "Registration Rights Agreement") among
the Company and the original purchaser of the Outstanding Notes (the "Initial
Purchaser"), the Company will bear certain offering expenses.

   THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES
    AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE
    SECURITIES AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION
        PASSED UPON THE ACCURACY OR ADEQUACY OF THIS PROSPECTUS.  ANY
            REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.

                             ----------------------

              The date of this Prospectus is              , 1997.
<PAGE>   4
     The Company will accept for exchange any and all Outstanding Notes
validly tendered on or prior to 5:00 p.m., New York City time on        , 1997,
unless extended (the "Expiration Date").  Tenders of Outstanding Notes may be
withdrawn at any time prior to 5:00 p.m., New York City time on the Expiration
Date; otherwise such tenders are irrevocable.  Firstar Bank of Minnesota, NA is
acting as Exchange Agent in connection with the Exchange Offer.  The Exchange
Offer is not conditioned upon any minimum principal amount of Outstanding Notes
being tendered for exchange, but is otherwise subject to certain customary
conditions.

     The Senior Secured Notes will bear interest at a rate of 11 1/2% per annum
payable semi-annually in cash in arrears on June 15 and December 15 of each
year, commencing December 15, 1997. Principal on the Senior Secured Discount
Notes will accrete to 100% of the face value thereof by June 15, 1999.
Commencing December 15, 1999, cash interest on the Senior Secured Discount
Notes will be payable semi-annually in arrears on June 15 and December 15 of
each year at a rate of 13% per annum. The Notes will mature on June 15, 2002.
The Notes are not redeemable prior to June 15, 2000, except that the Company
may redeem, at its option, prior to June 15, 2000, up to 35% of the original
aggregate principal amount of the Senior Secured Notes and up to 35% of the
Accreted Value (as defined) of the Outstanding Senior Secured Discount Notes
and the Senior Secured Discount Exchange Notes (together, the "Senior Secured
Discount Notes"), at the redemption prices set forth therein, plus accrued and
unpaid interest, if any, to and including the date of redemption, with the net
proceeds of any Equity Offering (as defined). On or after June 15, 2000, the
Notes will be redeemable at the option of the Company, in whole or in part, at
the redemption prices set forth therein, plus accrued and unpaid interest, if
any, to and including the date of redemption. Upon the occurrence of a Change
of Control (as defined), the Company will be required to make an offer to
purchase all of the outstanding Notes at a price equal to 101% of the principal
amount thereof, together with accrued and unpaid interest, if any, or, in the
case of any such offer to purchase Senior Secured Discount Notes prior to June
15, 1999, at a price equal to 101% of the Accreted Value thereof, in each case,
to and including the date of purchase. In addition, the Company will be
obligated, subject to certain conditions, to make an offer to purchase Notes
with Excess Cash (as defined) at a price equal to 105% of the principal amount
or Accreted Value thereof, as applicable, if such purchase occurs on or prior
to December 31, 1997, at a price equal to 108% of the principal amount or
Accreted Value thereof, as applicable, if such purchase occurs during the
period from January 1, 1998 through June 14, 2000, and thereafter at the
redemption prices set forth under "Description of the Exchange Notes --
Optional Redemption" herein, in each case, together with accrued and unpaid
interest, if any, to and including the date of purchase.

     The Exchange Notes will be senior obligations of the Company, secured by a
lien on substantially all existing and future assets of the Company, which
currently include (w) all of the capital stock of TransTexas Gas Corporation
("TransTexas") owned by the Company, (x) all of the outstanding common stock of
TransAmerican Refining Corporation ("TARC"), (y) a promissory note from
TransTexas to the Company in the principal amount of $450 million secured by a
mortgage on substantially all of TransTexas' assets, other than Inventory,
Receivables and Equipment (each as defined) and (z) a promissory note from TARC
to the Company in the principal amount of $920 million secured by a mortgage on
substantially all of TARC's assets, including all of the capital stock of
TransTexas owned by TARC, but excluding Inventory, Receivables and Equipment.
The liens on certain TEC assets securing the Notes and on the TARC assets
(other than the TARC Disbursement Account (as defined)) securing the promissory
notes to the Company will be subject to the liens securing the outstanding TARC
Notes (as defined) that were not retired pursuant to the TARC Notes Tender
Offer (as defined) until they are redeemed, repurchased or repaid.  Under
certain circumstances, Collateral (as defined) may be released from the liens
granted for the direct or indirect benefit of holders of the Notes and such
liens may be subordinated to liens granted to other creditors of the Company's
subsidiaries. See "Description of the Exchange Notes -- Collateral and
Security."

     The Outstanding Notes were sold by the Company on June 13, 1997 to the
Initial Purchaser in a transaction not registered under the Securities Act of
1933, as amended (the "Securities Act"), in reliance upon the exemption
provided by Section 4(2) of the Securities Act. The Initial Purchaser
subsequently placed the Outstanding Notes with qualified institutional buyers
in reliance upon Rule 144A under the Securities Act.   Accordingly, the
Outstanding Notes may not be reoffered, resold or otherwise transferred in the
United States unless so registered or unless an applicable exemption from the
registration requirements of the Securities Act is available.  The Exchange
Notes are being offered hereunder in order to satisfy the obligations of the
Company under the Registration Rights Agreement between the Company and the
Initial Purchaser.  See "The Exchange Offer."





                                       ii
<PAGE>   5
     Based on an interpretation by the staff of the Securities and Exchange
Commission (the "Commission") set forth in no-action letters issued to third
parties, the Company believes that Exchange Notes issued pursuant to this
Exchange Offer may be offered for resale, resold and otherwise transferred by a
holder who is not an affiliate of the Company without compliance with the
registration and prospectus delivery provisions of the Securities Act, provided
that the holder is acquiring the Exchange Notes in its ordinary course of
business and is not participating in and has no arrangement or understanding
with any person to participate in the distribution (within the meaning of the
Securities Act) of the Exchange Notes.  Persons wishing to exchange Outstanding
Notes in the Exchange Offer must represent to the Company that such conditions
have been met.

     Each broker-dealer that receives Exchange Notes for its own account
pursuant to the Exchange Offer (a "Participating Broker-Dealer") must
acknowledge that it will deliver a prospectus in connection with any resale of
Exchange Notes.  The Letter of Transmittal for the Exchange Offer states that
by so acknowledging and delivering a prospectus, a broker-dealer will not be
deemed to admit that it is an "underwriter" within the meaning of the
Securities Act.  This Prospectus, as it may be amended or supplemented from
time to time, may be used by a broker-dealer in connection with resales of
Exchange Notes received in exchange for Outstanding Notes where such
Outstanding Notes were acquired by such broker-dealer as a result of
market-making activities or other trading activities.  The Company has agreed
to make this Prospectus available to any Participating Broker-Dealer for use in
connection with any such resale for a period of up to 180 days from the date of
consummation of the Exchange Offer.  See "Plan of Distribution."

     The Company does not intend to list the Exchange Notes on any national
securities exchange or to seek the admission thereof to trading on The Nasdaq
Stock Market.  The Initial Purchaser has advised the Company that it intends to
make a market in the Exchange Notes; however, it is not obligated to do so and
any market-making activities may be discontinued at any time without notice.
Accordingly, no assurance can be given that an active public or other market
will develop for the Exchange Notes or as to the liquidity of or the trading
market for the Exchange Notes.

     Any Outstanding Notes not tendered and accepted in the Exchange Offer will
remain outstanding.  To the extent that any Outstanding Notes of other holders
are tendered and accepted in the Exchange Offer, a holder's ability to sell
untendered Outstanding Notes could be adversely affected.  Following
consummation of the Exchange Offer, the holders of Outstanding Notes will
continue to be subject to the existing restrictions upon transfer thereof.

                                  THE COMPANY

      As of September 15, 1997, the Company owned, directly or indirectly,
approximately 72% of the outstanding capital stock of TransTexas and all of the
outstanding common stock of TARC. The Company, through its subsidiaries,
conducts operations in two segments of the energy industry: exploration and
production of natural gas and petroleum refining.

                                   TRANSTEXAS

      TransTexas is engaged in the exploration for and development and
production of natural gas, primarily in South Texas. Since 1973, TransTexas has
drilled over 1,400 wells and discovered over 3.5 Tcfe of natural gas.
TransTexas' business strategy is to utilize its extensive experience gained
from over 20 years of drilling and operating wells in South Texas, to continue
to find, develop and produce reserves at a low cost. TransTexas has
traditionally performed most of its own well site preparation, drilling,
workover, completion, pipeline and production services.

      In 1994, as part of its strategy to expand its productive reserves beyond
the Lower Wilcox Lobo Trend (the "Lobo Trend") in Webb and Zapata counties in
South Texas, TransTexas began evaluating prospects that exhibited the potential
to add proved reserves of at least 50 Bcfe of natural gas per development area.
Since that time, TransTexas has evaluated over 300 potential areas and its
development of certain of these areas has resulted in substantial additions to
its reserves and production.

      In May 1997, TransTexas consummated a stock purchase agreement with an
unaffiliated buyer (the "Lobo Sale Agreement"), with an effective date of March
1, 1997, to effect the sale  (the "Lobo Sale") of the stock of TransTexas
Transmission Corporation ("TTC"), its subsidiary that owned substantially all
of TransTexas' Lobo Trend producing properties and related pipeline
transmission system, for a sales price of approximately $1.1 billion, subject
to adjustments as provided for in the Lobo Sale Agreement.  Purchase price
adjustments were made for, among other things: the value of certain NGLs and
stored hydrocarbons; the value of gas in TTC's pipeline; prepaid expenses
relating to post-effective date operations; post-closing expenses related to
pre-closing operations; the value of oil and gas produced and sold between the
effective date of the Lobo Sale Agreement and closing (approximately $44
million); property defects; and estimated costs associated with liabilities
incurred  before closing.  Purchase price adjustments made at the closing of
the Lobo Sale are subject to a review, reconciliation and resolution process.
With proceeds from the Lobo Sale, TransTexas repaid certain indebtedness and
other obligations, including production payments, in an aggregate amount of
approximately $84 million. The remaining net proceeds were used for the
repurchase or redemption of TransTexas' 11 1/2% Senior Secured Notes due 2002
(the "TransTexas Senior Secured Notes") and for general corporate purposes.





                                       1
<PAGE>   9
      As of February 1, 1997, TransTexas' net proved reserves in properties
remaining after the Lobo Sale (the "Continuing Operations"), as estimated by
Netherland, Sewell & Associates, Inc., were 404 Bcfe.  As of July 31, 1997,
after giving effect to the Lobo Sale, TransTexas owned approximately 650,000
gross (475,000 net) acres of mineral interests.

      TransTexas' average net daily natural gas production for the year ended
January 31, 1997, was approximately 420 MMcfd, for a total net production of
153.6 Bcf of natural gas. After giving effect to the Lobo Sale, TransTexas'
average net daily production  for the six months ended July 31, 1997 was
approximately 164 MMcfd of natural gas and 2,013 Bpd of crude oil and
condensate, for a total net production of 31.1 Bcfe.

      TransTexas' integrated drilling services division provides oil field
services including drilling, oil and natural gas well workover, stimulation and
completion, drilling fluids provision, pipeline construction and equipment
repair and maintenance to TransTexas. As of September 30, 1997, the assets of
this division included 25 land drilling rigs, nine workover rigs and two
fracture stimulation fleets. Complementary drilling, completion and workover
service equipment includes a ready-mix concrete plant, twin cementing trucks, a
coiled tubing unit, a snubbing unit, electric line and logging units, slickline
units, tag units and an extensive fleet of construction, inspection and other
rolling stock.

      TransTexas may contribute the assets of its drilling services division to
its wholly owned subsidiary, TransTexas Drilling Services, Inc. ("TTXD").
TransTexas is evaluating alternatives to maximize stockholder value with
respect to TTXD, including options such as a spin-off, a sale to a third party,
a merger or another business combination. In connection with the Lobo Sale,
TransTexas entered into a long-term agreement, which can be transferred to
TTXD, pursuant to which it will provide drilling and certain other services to
the new operator of the Lobo Trend properties divested in the Lobo Sale.
TransTexas has also recently begun to provide drilling services to other third
parties.

      The address of the Company's principal executive offices is 1300 North
Sam Houston Parkway East, Suite 200, Houston, Texas 77032-2949 and its
telephone number at that address is (281) 986-8822.

                                      TARC

      TARC owns a large petroleum refinery strategically located in the Gulf
Coast region along the Mississippi River, approximately 20 miles from New
Orleans, Louisiana. TARC's business strategy is to modify, expand and
reactivate its refinery and to maximize its gross refining margins by
converting low-cost, heavy, sour crude oils into high-value, light petroleum
products, including primarily gasoline and heating oil. In February 1995, TARC
began a construction and expansion program designed to reactivate the refinery
and increase its complexity. From February 1995 through April 1997, TARC spent
approximately $245 million on this program, procured a majority of the
essential equipment required and completed substantially all of the process
design engineering and a substantial portion of the remaining engineering
necessary to complete this project.

      The transactions described below in "--Recent Events" (the
"Transactions"), when completed, will result in proceeds to TARC in excess of
the $427 million estimated budget for a modified two-phase construction and
expansion program (the "Capital Improvement Program"), which is designed to
reactivate the refinery and increase its complexity.  Phase I of the Capital
Improvement Program includes the completion and start-up of several units,
including the Delayed Coking Unit, one of the refinery's major conversion
units. TARC estimates that Phase I will be completed at a cost of $223 million,
will be tested and operational by September 30, 1998, and will result in the
refinery having the capacity to process up to 200,000 Bpd of sour crude oil.
Phase II of the Capital Improvement Program includes the completion and
start-up of the Fluid Catalytic Cracking Unit utilizing state-of-the-art
milli-second catalytic cracking ("MSCC((SM))") technology and the installation
of additional equipment expected to further improve operating margins by
allowing for a significant increase in the refinery's capacity to produce
gasoline. TARC estimates that Phase II will be completed at a cost of $204
million and will be tested and operational by July 31, 1999.  After completion
of the Capital Improvement Program, TARC will own and operate one of the
largest independent refineries in the Gulf Coast region, with a replacement
cost estimated by management to be approximately $1.4 billion.

                                 RECENT EVENTS

      TEC NOTES OFFERING.  On June 13, 1997, TEC completed a private offering
(the "Original Notes Offering") of $475 million aggregate principal amount of
the Outstanding Senior Secured Notes and $1.13 billion aggregate principal
amount of the Outstanding Senior Secured Discount Notes for net proceeds of
approximately $1.3 billion.  The Outstanding Notes are senior obligations of
TEC, secured by a lien on substantially all of its existing and future assets,
including the intercompany loans described below.

      The Outstanding Senior Secured Notes bear interest at a rate of 11 1/2%
per annum payable semi-annually in cash in arrears on June 15 and December 15 of
each year, commencing December 15, 1997.  Principal on the Outstanding Senior
Secured Discount Notes will accrete to 100% of the face value thereof by June
15, 1999.  Commencing December 15, 1999, cash interest on the Outstanding Senior
Secured Discount Notes will be payable semi-annually in arrears on June 15 and
December 15 of each year at a rate of 13% per annum.  The Outstanding Notes will
mature on June 15, 2002.  The Outstanding Notes are not redeemable prior to June
15, 2000, except that the Company may redeem, at its option, prior to June 15,
2000, up to 35% of the original aggregate principal amount of the Outstanding
Senior Secured Notes and up to 35% of the accreted value of the Outstanding
Senior Secured Discount Notes, at the redemption prices set forth in the
Indenture, plus accrued and unpaid interest, if any, to and including the date
of redemption, with the net proceeds of any equity offering.  On or after June
15, 2000, the Outstanding Notes will be redeemable at the option of TEC, in
whole or in part, at the redemption prices set forth in the Indenture, plus
accrued and unpaid interest, if any, to and including the date of redemption.
Upon the occurrence of a Change of Control (as defined), TEC will be required to
make an offer to purchase all of the then outstanding Outstanding Notes at a
price equal to 101% of the principal amount thereof, together with accrued and
unpaid interest, if any, or, in the case of any such offer to purchase
Outstanding Senior Secured Discount Notes prior to June 15, 1999, at a price
equal to 101% of the accreted value thereof, in each case, to and including the
date of purchase.  In addition, TEC will be obligated, subject to certain
conditions, to make an offer to purchase Outstanding Notes with Excess Cash (as
defined) at a price equal to 105% of the principal amount of accreted value
thereof, as applicable, if such purchase occurs on or prior to December 31,
1997, at a price equal to 108% of the principal amount or accreted value
thereof, as applicable, if such purchase occurs during the period from January
1, 1998 through June 14, 2000, and thereafter at the redemption prices set forth
in the Indenture in each case, together with accrued and unpaid interest, if
any, to and including the date of purchase.  The Exchange Notes are
substantially identical to the Outstanding Notes in the above respects.

      INTERCOMPANY LOANS TO TRANSTEXAS AND TARC.  With the proceeds of the
Original Notes Offering, TEC made intercompany loans to TransTexas (the
"TransTexas Intercompany Loan") and TARC (the "TARC Intercompany Loan" and,
together with the TransTexas Intercompany Loan, the "Intercompany Loans").  The
TransTexas Intercompany Loan (i) is in the principal amount of $450 million,
(ii) bears interest at a rate of 10 7/8% per annum, payable semi-annually in
cash in arrears and (iii) is currently secured by a security interest in
substantially all of the assets of  TransTexas, excluding Inventory,
Receivables and Equipment.  The TARC Intercompany Loan (i) is in the original
amount of $676 million, (ii) accretes principal at 16% per annum, compounded
semi-annually, until June 15, 1999, to a final accreted value of $920 million,
and thereafter pays interest semi-annually in cash in arrears on the accreted
value thereof, at a rate of 16% per annum and (iii) is currently secured by a
security interest in substantially all of TARC's assets other than Inventory,
Receivables and Equipment.  The Intercompany Loans will mature on June 1, 2002.
The agreements governing the Intercompany Loans (the "Intercompany Loan
Agreements") contain certain restrictive covenants, including, among others,
limitations on incurring additional debt, asset sales, dividends and
transactions with affiliates.  TARC used approximately $103 million of the
proceeds of the TARC Intercompany Loan to repay certain indebtedness, including
$36 million of senior secured notes of TARC that were issued in March 1997 and
$66 million of advances and notes payable owed to an affiliate, and used
approximately $437 million to complete the TARC Notes Tender Offer (described
below).  Remaining proceeds will be used for the Capital Improvement Program
and for general corporate purposes.  Upon the occurrence of a Change of Control
(as defined), TEC will be required to make an offer to purchase all of the
outstanding Notes at a price equal to 101% of the principal amount thereof,
together with accrued and unpaid interest, if any, or, in the case of any such
offer to purchase the Senior Secured Discount Notes prior to June 15, 1999, at
a price equal to 101% of the accreted value thereof, in each case, to and
including the date of purchase.





                                       3
<PAGE>   11
Pursuant to the terms of the Intercompany Loans, TEC may require TransTexas and
TARC to pay a pro rata share of the purchase price paid by TEC.

      TARC WARRANTS TENDER OFFER.  On June 13, 1997, TEC completed a tender
offer for all of the outstanding common stock purchase warrants of TARC ("TARC
Warrants") at a price of $4.50 per warrant.  Pursuant to the tender offer, TEC
purchased 7,335,452 TARC Warrants for an aggregate purchase price of
approximately $33 million.  TEC or TARC may repurchase additional TARC
Warrants, and  TARC intends to enter into a merger with one of its affiliates
pursuant to which each remaining TARC Warrant would become exercisable (at an
exercise price of $.01) to receive $4.51 of cash instead of one share of common
stock of TARC.

      DIVIDEND TO TRANSAMERICAN.  TEC paid a dividend to TransAmerican in the
amount of $23 million.  A portion of the dividend was used to repay the debt of
an affiliate, which had been secured by a pledge of 3.7 million shares of
TransTexas common stock.  In connection with the TEC Notes Offering,
TransAmerican contributed the 3.7 million shares of TransTexas common stock to
TEC.

      TEC PREFERRED STOCK REDEMPTION.  On June 17, 1997, TEC redeemed all of
its outstanding preferred stock for an aggregate amount of $100,000, plus
accrued and unpaid dividends (the "TEC Preferred Stock Redemption").

      LOBO SALE.  On May 29, 1997, TransTexas entered into and consummated a
stock purchase agreement with an unaffiliated buyer (the "Lobo Sale
Agreement"), with an effective date of March 1, 1997, to effect the sale  (the
"Lobo Sale") of the stock of TransTexas Transmission Corporation ("TTC"), its
subsidiary that owned substantially all of TransTexas' Lobo Trend producing
properties and related pipeline transmission system, for a sales price of
approximately $1.1 billion, subject to adjustments as provided for in the Lobo
Sale Agreement.  Purchase price adjustments were made for, among other things:
the value of certain NGLs and stored hydrocarbons; the value of gas in TTC's
pipeline; prepaid expenses relating to post-effective date operations;
post-closing expenses related to pre-closing operations; the value of oil and
gas produced and sold between the effective date of the Lobo Sale Agreement and
closing (approximately $44 million);  property defects; and estimated costs
associated with liabilities incurred  before closing.    Purchase price
adjustments made at the closing of the Lobo Sale are subject to a review,
reconciliation and resolution process.   With proceeds from the Lobo Sale,
TransTexas repaid certain indebtedness and other obligations, including
production payments, in an aggregate amount of approximately $84 million.  The
remaining net proceeds were used for the repurchase or redemption of the
TransTexas Senior Secured Notes and for general corporate purposes.

      TRANSTEXAS SENIOR SECURED NOTES TENDER OFFER.  On June 13, 1997,
TransTexas completed the Tender Offer for the TransTexas Senior Secured Notes
for 111 1/2% of their principal amount (plus accrued and unpaid interest).
Approximately $785.4 million principal amount of TransTexas Senior Secured
Notes were tendered and accepted by TransTexas.   The TransTexas Senior Secured
Notes remaining outstanding were called for redemption on June 30, 1997
pursuant to the terms of the indenture governing such notes.

      TRANSTEXAS SUBORDINATED NOTES EXCHANGE OFFER.  On June 19, 1997,
TransTexas completed an exchange offer, pursuant to which it exchanged
approximately $115.8 million aggregate principal amount of its 13 3/4% Senior
Subordinated Notes due 2001 (the "TransTexas Subordinated Notes") for all of
its 13 1/4% Senior Subordinated Notes due 2003 (the "Old TransTexas
Subordinated Notes").  The indenture governing the TransTexas Subordinated
Notes includes certain restrictive covenants, including, among others,
limitations on incurring additional debt, asset sales, dividends and
transactions with affiliates.

      SHARE REPURCHASE PROGRAM.  TransTexas has implemented a share repurchase
program (the "Share Repurchase Program") pursuant to which it plans to
repurchase common stock from its public stockholders and from its affiliates,
including TEC and TARC, in an aggregate amount of approximately $399 million in
value of stock purchased.   It is anticipated that TransTexas will acquire four
times the number of shares from its affiliated stockholders that it acquires
from its public stockholders.  Shares may be purchased through open market
purchases, negotiated transactions or tender offers, or combination of the
above.   It is anticipated that the price paid to affiliated stockholders will
equal the





                                       4
<PAGE>   12
weighted average price paid to purchase shares from the public stockholders.
As of September 30, 1997, approximately 3.9 million shares had been repurchased
from public stockholders  for an aggregate purchase price of approximately
$61.4 million and approximately 12.6 million shares had been repurchased from
TARC and TEC for an aggregate purchase price of $201 million.

      TRANSTEXAS DISBURSEMENT ACCOUNT.   Pursuant to a disbursement agreement
(the "TransTexas Disbursement Agreement") among TransTexas, TEC, the Trustee,
and Firstar Bank of Minnesota, N.A. as disbursement agent (the "TransTexas
Disbursement Agent"), approximately $399 million of the proceeds of the
TransTexas Intercompany Loan was placed in an account (the "TransTexas
Disbursement Account") to be held and invested by the disbursement agent until
disbursed.  Funds in the TransTexas Disbursement Account have been and will be
disbursed to TransTexas as needed to fund the Share Repurchase  Program.
TransTexas may at any time request disbursement of interest earned on the funds
in the TransTexas Disbursement Account.

      TARC NOTES TENDER OFFER.  On June 13, 1997, TARC completed a tender offer
(the "TARC Notes Tender Offer") for its (i) Guaranteed First Mortgage Notes due
2002 (the "TARC Mortgage Notes") for 112% of their principal amount (plus
accrued and unpaid interest) and (ii) Guaranteed First Mortgage Discount Notes
due 2002 (the "TARC Discount Notes" and, together with the TARC Mortgage Notes,
the "TARC Notes") for 112% of their accreted value.  In connection with the
TARC Notes Tender Offer, TARC obtained consents from holders of the TARC Notes
to certain waivers under, and amendments to, the indenture governing the TARC
Notes (the "TARC Notes Indenture"), which eliminated or modified certain of the
covenants and other provisions contained in the TARC Notes Indenture.  TARC
Mortgage Notes and TARC Discount Notes with an aggregate carrying value of $423
million were tendered and accepted by TARC at a cost to TARC of approximately
$437 million (including accrued interest, premiums and other costs).  As of
July 31, 1997, TARC Mortgage Notes and TARC Discount Notes with an aggregate
carrying value of $15.7 million remained outstanding.

      DISBURSEMENT ACCOUNT.  Pursuant to a disbursement agreement (the "TARC
Disbursement Agreement") among TARC, TEC, the Trustee, Firstar Bank of
Minnesota, N.A. as disbursement agent (the "Disbursement Agent"), and Baker &
O'Brien, Inc., as construction supervisor (the "Construction Supervisor"), $208
million of the net proceeds from the sale of the Outstanding Notes was placed
into accounts in the name of TARC ($135 million) and TEC ($73 million)
(together, the "TARC Disbursement Account") to be held and invested by the
Disbursement Agent until disbursed.  In addition, anticipated proceeds to TEC
and TARC of approximately $300 million from the Share Repurchase Program have
been or will be deposited in the TARC Disbursement Account as purchases are
made.  All funds in the TARC Disbursement Account are pledged as security for
the repayment of the Notes.

      The Disbursement Agent will make disbursements for the Capital
Improvement Program out of the TARC Disbursement Account in accordance with
requests made by TARC and approved by the Construction Supervisor.  The
Construction Supervisor is required to review each such disbursement request by
TARC.  No disbursements may be made from the TARC Disbursement Account for
purposes other than the Capital Improvement Program other than (i) up to $1.5
million per month (except for December 1997, in which disbursements may be up
to $4.5 million) to fund administrative costs and certain taxes and insurance
payments, not in excess of $25.5 million in the aggregate; provided, that if
less than $1.5 million is spent in any month (or less than $4.5 million is
spent in December 1997) the amounts that may be disbursed in one or more
subsequent months will be increased by the amount of such difference, (ii) up
to $50 million for feedstock upon certification by the Construction Supervisor
of the Mechanical Completion (as defined) of the Delayed Coking Unit and
associated facilities, (iii) up to $19 million to pay interest on, and to
redeem, repurchase, defease, or otherwise retire the remaining TARC Notes and
(iv) up to $7.0 million for outstanding accounts payable.  In addition,
interest income from the Disbursement Account may be used for the Capital
Improvement Program or disbursed to fund administrative and other costs of TARC
and TEC.  As of July 31, 1997, $24.9 million had been disbursed to TARC out of
the Disbursement Account for use in the Capital Improvement Program and $7.0
million for general corporate purposes.

                                      applicable interpretations of the staff of the Commission do not permit the
                                      Company to effect the Exchange Offer, or if certain other conditions apply,  the
                                      Company has agreed to file a shelf registration statement (the "Shelf Registration
                                      Statement") covering resales of the Outstanding Notes.  See "The Exchange Offer --
                                      Shelf Registration Statement."

The Exchange Offer  . . . . . .       The Company is offering to exchange $1,000 principal amount (as shown on the face
                                      thereof) of the Exchange Notes for each $1,000 principal amount (as shown on the
                                      face thereof) of Outstanding Notes.  As of the date hereof, $475,000,000 aggregate
                                      principal amount of the Outstanding Senior Secured Notes are outstanding and
                                      $1,130,000,000 aggregate principal amount (as shown on the face thereof) of
                                      Outstanding Senior Secured Discount Notes are outstanding.  The Company will issue
                                      the Exchange Notes to holders of Outstanding Notes on                   , 1997
                                      (the "Exchange Date").

                                      Based on an interpretation of the staff of the Commission set forth in no-action
                                      letters issued to third parties, the Company believes that Exchange Notes issued
                                      pursuant to the Exchange Offer in exchange for Outstanding Notes may be offered
                                      for resale, resold and otherwise transferred by any holder thereof (other than any
                                      such holder which is an "affiliate" of the Company within the meaning of Rule 405
                                      under the Securities Act) without compliance with the registration and prospectus
                                      delivery provisions of the Securities Act, provided that such Exchange Notes are
                                      acquired in the ordinary course of such holder's business and that such holder
                                      does not intend to participate and has no arrangement or understanding with any
                                      person to participate in the distribution of such Exchange Notes.

                                      Each Participating Broker-Dealer must acknowledge that it will deliver a
                                      prospectus in connection with any resale of Exchange Notes.  The Letter of
                                      Transmittal for the Exchange Offer states that by so acknowledging and by
                                      delivering a prospectus, a broker-dealer will not be deemed to admit that it is an
                                      "underwriter" within the meaning of the Securities Act.  This Prospectus, as it
                                      may be amended or supplemented from time to time, may be used by a broker-dealer
                                      in connection with resales of Exchange Notes received in exchange for Outstanding
                                      Notes where such Outstanding Notes were acquired by such broker-dealer as a result
                                      of market-making activities or other trading activities.  The Company has agreed
                                      to make this Prospectus available to any Participating Broker-Dealer for use in
                                      connection with any such resale for a period of up to 180 days from the
                                      consummation of the Exchange Offer.  See "Plan of Distribution."

                                      Any holder who tenders in the Exchange Offer with the intention to participate, or
                                      for the purpose of participating, in a distribution of the Exchange Notes cannot
                                      rely on the position of the staff of the Commission enunciated in Exxon Capital
                                      Holdings Corporation (available April 13, 1989) or similar no-action letters and,
                                      in the absence of an exemption therefrom, must comply with the registration and
                                      prospectus delivery requirements of the Securities Act in connection with the
                                      resale transaction.  Failure to comply with such requirements in such instance may
                                      result in such holder incurring liability under the Securities Act for which the
                                      holder is not indemnified by the Company.

Expiration Date . . . . . . . .       5:00 p.m., New York City time on                  , 1997.

Procedures for Tendering

                                      complete, sign and date the accompanying Letter of Transmittal, or a facsimile
                                      thereof, in accordance with the instructions contained herein and therein, and
                                      mail or otherwise deliver such Letter of Transmittal, or such facsimile, together
                                      with the Outstanding Notes and any other required documentation to the Exchange
                                      Agent at the address set forth herein or otherwise comply with the procedures for
                                      tendering set forth in "The Exchange Offer -- Procedures for Tendering."  By
                                      tendering Outstanding Notes, each holder will represent to the Company that, among
                                      other things, the holder or the person receiving such Exchange Notes, whether or
                                      not such person is the holder, is acquiring the Exchange Notes in the ordinary
                                      course of business and that neither the holder nor any such other person has any
                                      arrangement or understanding with any person to participate in the distribution of
                                      such Exchange Notes.  In lieu of physical delivery of the certificates
                                      representing Outstanding Notes, tendering holders may transfer Outstanding Notes
                                      pursuant to the procedures for book-entry transfer as set forth under "The
                                      Exchange Offer--Procedures for Tendering."

Special Procedures for
  Beneficial Owners . . . . . .       Any beneficial owner whose Outstanding Notes are registered in the name of a
                                      broker-dealer, commercial bank, trust company or other nominee and who wishes to
                                      tender should contact such registered holder promptly and instruct such registered
                                      holder to tender on such beneficial owner's behalf.

                                      If such beneficial owner wishes to tender on such owner's own behalf, such owner
                                      must, prior to completing and executing the Letter of Transmittal and delivering
                                      its Outstanding Notes, either make appropriate arrangements to register ownership
                                      of the Outstanding Notes in such owner's name or obtain a properly completed bond
                                      power from the registered holder.  The transfer of registered ownership may take
                                      considerable time.

Guaranteed Delivery
  Procedures  . . . . . . . . .       Holders of Outstanding Notes who wish to tender their Outstanding Notes and whose
                                      Outstanding Notes are not immediately available or who cannot deliver their
                                      Outstanding Notes, the Letter of Transmittal or any other documents required by
                                      the Letter of Transmittal to the Exchange Agent (or comply with the procedures for
                                      book-entry transfer) prior to the Expiration Date must tender their Outstanding

                                      Expiration Date pursuant to the procedures described under "The Exchange Offer --
                                      Withdrawal of Tenders."

Acceptance of Outstanding
  Notes and Delivery of
  Exchange Notes  . . . . . . .       Subject to certain conditions, the Company will accept for exchange any and all
                                      Outstanding Notes that are properly tendered in the Exchange Offer prior to 5:00

                                      Exchange Offer -- Terms of the Exchange Offer."

Federal Income Tax
  Consequences  . . . . . . . .       The exchange pursuant to the Exchange Offer should not be a taxable event for
                                      federal income tax purposes.  See "Certain Federal Income Tax Consequences."

Effect on Holders of
  Outstanding Notes . . . . . .       As a result of the making of this Exchange Offer, the Company will have fulfilled
                                      one of its obligations under the Registration Rights Agreement, and, with certain
                                      exceptions noted below, holders of Outstanding Notes who do not tender their
                                      Outstanding Notes will not have any further registration rights under the
                                      Registration Rights Agreement or otherwise.  Such holders will continue to hold
                                      the untendered Outstanding Notes and will be entitled to all the rights and
                                      subject to all the limitations applicable thereto under the Indenture, except to
                                      the extent such rights or limitations, by their terms, terminate or cease to have
                                      further effectiveness as a result of the Exchange Offer.  All untendered
                                      Outstanding Notes will continue to be subject to certain restrictions on transfer.
                                      Accordingly, if any Outstanding Notes are tendered and accepted in the Exchange
                                      Offer, the trading market of the untendered Outstanding Notes could be adversely
                                      affected.  See "Risk Factors -- Exchange Offer Procedures."

Private Exchange Notes  . . . .       The Registration Rights Agreement provides that if, prior to consummation of the
                                      Exchange Offer, the Initial Purchaser holds any Outstanding Notes acquired by it
                                      and having the status of an unsold allotment in the initial distribution,  the
                                      Company upon the request of such Initial Purchaser shall, simultaneously with the
                                      delivery of the Exchange Notes in the Exchange Offer, issue and deliver to the
                                      Initial Purchaser, in exchange (the "Private Exchange") for such Outstanding Notes
                                      held by the Initial Purchaser a like principal amount of debt securities of the
                                      Company that are identical in all material respects to the Exchange Notes (the
                                      "Private Exchange Notes") (and which were issued pursuant to the same indenture as
                                      the Exchange Notes).  The Private Exchange Notes are not covered by the
                                      registration statement of which this Prospectus is a part and are not being
                                      offered hereby.  Any Private Exchange Notes will be entitled to all the rights and
                                      subject to all the limitations applicable thereto under the Indenture, and will be
                                      subject to the same restrictions on transfer applicable to untendered Outstanding
                                      Notes.  See "The Exchange Offer -- Consequences of Failure to Exchange." Pursuant
                                      to the Registration Rights Agreement, however, holders of Private Exchange Notes
                                      have certain rights to require the Company to file and maintain a shelf
                                      registration statement that would allow resale of such Private Exchange Notes.

<S>                                    <C>
Securities Offered  . . . . . .        $475,000,000 aggregate principal amount of 11 1/2% Series B Senior Secured Notes
                                       due 2002 and $1,130,000,000 aggregate principal amount (as shown on the face
                                       thereof) of 13% Series B Senior Secured Discount Notes due 2002.

Maturity Date . . . . . . . . .        June 15, 2002 (the "Maturity Date").

Interest on Senior Secured
Exchange Notes  . . . . . . . .        The Senior Secured Exchange Notes will bear interest at a rate of  11 1/2% per
                                       annum.  Interest will accrue from the most recent date on which interest has been
                                       paid or, if no interest has been paid, the issue date of the Outstanding Senior
                                       Secured Notes.  Interest on the Senior Secured Exchange Notes will be payable 
                                       semi-annually in cash in arrears on June 15 and December 15 of each year,
                                       commencing December 15, 1997.

Interest on Senior Secured
Discount Notes  . . . . . . . .        The Senior Secured Discount Exchange Notes will accrete at a rate of 13% per
annum                                  (compounded semi-annually on June 15 and December 15 of each year) to 100% of the
                                       face value thereof by June 15, 1999.  On their issue date the Senior Secured
                                       Discount Exchange Notes will have the same Accreted Value as the Outstanding
                                       Senior Secured Discount Notes on that date.  Cash interest on the Senior Secured
                                       Discount Exchange Notes will be payable semi-annually in arrears on June 15 and
                                       December 15 of each year, commencing December 15, 1999, at a rate of 13% per
                                       annum. For federal income tax purposes, the Senior Secured Discount Exchange
                                       Notes will be issued with original issue discount.  The amount of original issue
                                       discount will be equal to the difference between the issue price of the
                                       Outstanding Senior Secured Discount Notes and the sum of all payments provided
                                       for under the terms of the Senior Secured Discount Notes (whether denominated as
                                       principal or interest), less the amount of original issue discount that will have
                                       accrued on the Outstanding Senior Secured Discount Notes until the Exchange Date.
                                       Holders of Senior Secured Discount Exchange Notes generally will be required to
                                       include original issue discount in ordinary income over the period commencing
                                       upon the issuance of the Senior Secured Discount Exchange Notes until June 15,
                                       1999 that they hold the Senior Secured Discount Exchange Notes in advance of the
                                       receipt of cash attributable thereto. See "Certain Federal Income Tax
                                       Considerations--Taxation of the Notes."

Ranking . . . . . . . . . . . .        The Notes will be senior indebtedness of the Company. Immediately after
                                       consummation of the Exchange Offer, the Notes will be the only outstanding
                                       indebtedness of the Company, other than the Company's guaranty of the TARC Notes
                                       that remain outstanding.  The Indenture restricts the Company's and its
                                       subsidiaries' abilities to incur other indebtedness and restricts the Company's
                                       and its subsidiaries' abilities to grant additional liens on their assets except
                                       for Permitted Liens (as defined), in each case with certain exceptions. The Notes
                                       will be effectively subordinated to the indebtedness and other liabilities of the
                                       Company's subsidiaries, except to the extent that the Company is recognized as a
                                       creditor of such entity. As of July 31, 1997, TransTexas and TARC had
                                       approximately $159.4 million (excluding the TransTexas Intercompany Loan) and
                                       $16.6 million (excluding the TARC Intercompany Loan) of indebtedness and other
                                       liabilities, respectively, that ranked senior to the Notes. See "Description of
                                       the Exchange Notes--Covenants--Limitation on Incurrences of Additional Debt and
                                       Issuances of Disqualified Capital Stock" and "Description of the Exchange

Security  . . . . . . . . . . .        The Outstanding Notes are and the Exchange Notes will be senior obligations of
                                       the Company, secured by a lien on substantially all existing and future assets of
                                       the Company, which currently includes (w) all of the capital stock of TransTexas
                                       owned by the Company, (x) all of the outstanding common stock of TARC, (y) the
                                       TransTexas Intercompany Loan in the principal amount of $450 million, secured by

                                       excluding Inventory, Receivables and Equipment.  The liens on certain TEC assets
                                       securing the Notes and on the TARC assets (other than the TARC Disbursement
                                       Account) securing the TARC Intercompany Loan will be subject to the liens
                                       securing any outstanding TARC Notes until they are redeemed, repurchased,
                                       defeased or repaid. See "Description of the Exchange Notes--Collateral and
                                       Security." The Indenture prohibits the Company and certain of its subsidiaries
                                       from incurring or permitting any liens on their assets and properties other than
                                       Permitted Liens. See "Description of the Exchange Notes--Covenants--Limitation on
                                       Liens."

                                       payable semi-annually in cash in arrears. The TARC Intercompany Loan will accrete
                                       for two years from the date made and will thereafter bear cash interest, both at
                                       a rate of 16% per annum, compounded semi-annually. The Intercompany Loans each
                                       will mature on June 1, 2002.

                      SUMMARY FINANCIAL AND OPERATING DATA

         On January 30, 1996, TEC changed its fiscal year end for financial
reporting purposes from July 31 to January 31. The following table sets forth
selected financial and operating data of TEC and its predecessor for and at the
end of each of the four years ended July 31, 1995, the six months ended January
31, 1995 and 1996, the years ended January 31, 1996 and 1997 and the six months
ended July 31, 1996 and 1997.  The financial data for the years ended July 31,
1992, 1993, 1994 and 1995, the six months ended January 31, 1996 and the year
ended January 31, 1997, are derived from the audited financial statements of
TEC. The financial data for the six months ended January 31, 1995, the year
ended January 31, 1996 and the six months ended July 31, 1996 and 1997 are
derived from the unaudited financial statements of TEC and contain all
adjustments (consisting only of normal recurring accruals) necessary, in the
opinion of management of TEC, for a fair presentation thereof.  The financial
data for fiscal years ended July 31, 1992 and 1993 represent the results of
operations and financial position of TEC's predecessor prior to the reactivation
of the refinery. During these periods, TARC had only maintenance expenses and
lease income for storage facilities. The data for the year ended July 31, 1994
reflects the limited operations of the refinery commenced in March 1994 and
expenses related to reactivation of portions of the refinery. Subsequent to
March 1994, TARC has operated the No. 2 Vacuum Unit intermittently. TARC does
not consider its historical results to be indicative of future results.

(1)      Per share data for years prior to July 31, 1995 is omitted because
         TEC's predecessor was not a separate entity with its own capital
         structure.

(2)      Earnings were inadequate to cover fixed charges by $138.7 million,
         $26.9 million, $60.4 million, $172.5 million and $18.3 million for the
         year ended July 31, 1995, for the six months ended January 31, 1995
         and 1996 and the years ended January 31, 1996 and 1997, respectively.

(3)      Includes a 3.5 Bcf adjustment resulting from a favorable litigation
         settlement.

(4)      Sales volumes for the year ended January 31, 1997 and the six months
         ended July 31, 1997, include 32.0 Bcf and 7.3 Bcf, respectively,
         delivered pursuant to volumetric production payments

(5)      Average price calculations for the year ended January 31, 1997 and
         the six months ended July 31, 1997, include prices for amounts 
         delivered to third parties under volumetric production payments. The 
         average gas prices for TransTexas' undedicated production for these 
         periods were $2.39 per Mcf and $1.91 per Mcf, respectively. The gas 
         price does not include the effect of hedging.

(6)      These reserve data are estimates of TransTexas' proved reserves as of
         August 1, 1992, 1993, 1994 and 1995 and February 1, 1996 and 1997, as
         evaluated by Netherland Sewell & Associates, Inc. No reserve estimates
         were made for the six-month periods ended July 31, 1996 and 1997. See 
         "Risk Factors-- General Risk Factors -- Risks Related to Forward 
         Looking Statements and Estimates."

(7)      As of February 1, 1997, the sales price used for purposes of
         estimating TransTexas' proved reserves and the future net cash flow
         from those reserves was $3.17 Mcf of natural gas and $23.99 per Bbl of
         condensate and oil.

(8)      For all periods prior to the Asset Transfer (as defined), data
         excludes all cash and accounts receivable because those assets were
         not transferred to TransTexas in the Asset Transfer. Working capital
         at July 31, 1995 and 1996, and January 31, 1996 and 1997, includes 
         $44.7 million, $46.0 million, $46.0 million and $46.0 million, 
         respectively, in a restricted interest reserve account pursuant 
         to the Indenture governing the TransTexas Senior Secured Notes.

(9)      Net income (loss) is prior to the preferred stock dividends of
         $19,000 for the year ended January 31, 1997 and the six months
         ended July 31, 1996 and 1997.

                                  RISK FACTORS

         Prospective investors in the Exchange Notes should carefully consider
the risk factors set forth below as well as the other information contained in
this Prospectus or incorporated by reference herein.

GENERAL RISK FACTORS

         SIGNIFICANT LEVERAGE. At July 31, 1997, the Company's total short- and
long-term debt was approximately $1,529.7 million, which represented
approximately 86.2% of the total capitalization of the Company.  In addition,
the accretion of original issue discount on the Senior Secured Discount Notes
will increase the indebtedness represented by the Notes to approximately $1.6
billion by June 15, 1999.

         At July 31, 1997, the total short- and long-term debt of TransTexas
was approximately $596.1 million, which represented approximately 70.2% of the
total capitalization of TransTexas.  The total long-term debt of TARC was
approximately $705.7 million, which represented approximately 95.6% of the
total capitalization of TARC.  In addition, the accretion of value on the TARC
Intercompany Loan will increase the indebtedness represented thereby to $920
million by June 15, 1999. Further, earnings adjusted to eliminate certain
non-recurring gains of TransTexas and TARC for the year ended January 31, 1997,
after giving effect to the Transactions, would have been inadequate to cover
pro forma fixed charges by approximately $61.2 million and $123.6 million,
respectively. The high degree of leverage of TransTexas and TARC will have
significant consequences, including (i) a substantial portion of TransTexas'
and TARC's net cash provided by operations will be committed to the payment of
their interest expense and principal repayment obligations, (ii) TransTexas'
cash flow will be more sensitive to fluctuations in natural gas prices than
less highly leveraged companies, (iii) TARC's cash flow will be more sensitive
to fluctuations in feedstock costs and refined product prices than less highly
leveraged companies and (iv) TransTexas and TARC will be more highly leveraged
than other companies in their industries, which may place them at a competitive
disadvantage.

         The Company is the sole obligor with respect to the Outstanding Notes
and will be the sole obligor with respect to the Exchange Notes, and the Notes
are not obligations of, nor are they guaranteed by, any of the Company's
subsidiaries. The Company is a holding company with no business operations, and
its only sources of liquidity will be payments on the Intercompany Loans or
other loans to its subsidiaries, dividends on stock of its subsidiaries,
interest on funds in the TARC Disbursement Account and, in limited
circumstances as permitted by the Indenture, sales of stock of its
subsidiaries. The Company's holding company structure could adversely affect
the Company's ability to meet its obligations to the holders of the Notes.
There can be no assurance that TransTexas or TARC will generate sufficient cash
flow from operations to pay interest on or repay the principal amount of the
Intercompany Loans when such amounts become due. See "Management's Discussion
and Analysis of Financial Condition and Results of Operations--Liquidity and
Capital Resources."  In addition, any right of the Company to receive assets of
TransTexas, TARC, TTXD or any of their subsidiaries upon their liquidation or
recapitalization (and the consequent right of holders of the Notes to
participate in those assets) will be subordinate to the claims of creditors of
TransTexas, TARC, TTXD or any of their subsidiaries, as applicable, except to
the extent that the Company is itself recognized as a creditor of such entity.
TARC's ability to satisfy its principal and interest obligations on the TARC
Intercompany Loan from its cash flow from operations will depend on its ability
to complete its refinery and attain an adequate level of profitability.  There
can be no assurance that the Company's subsidiaries will be legally permitted
to pay dividends to the Company prior to the Maturity Date of the Notes.
Further, it is anticipated that any credit facility entered into by any of the
Company's subsidiaries will restrict such subsidiary's ability to pay dividends
to the Company. The Company, TransTexas and TARC may require sources of
liquidity other than cash flow from operations, including asset sales or equity
or debt financings, to retire or otherwise refinance the principal amount of
the Notes, the TransTexas Intercompany Loan and the TARC Intercompany Loan,
respectively, on or prior to maturity.

         ADEQUACY OF COLLATERAL; RISKS OF FORECLOSURE. The Company has granted
and pledged to the Trustee, for the ratable benefit of the holders of the
Notes, a security interest in substantially all of the assets of the Company,
including without limitation the Intercompany Loans and the stock of TransTexas
and TARC owned by the Company. The Intercompany Loans are secured obligations
of each obligor. The TransTexas Intercompany Loan is secured by a mortgage on
substantially all of TransTexas' assets, other than Inventory, Receivables and
Equipment and the TARC Intercompany Loan is secured by a mortgage on
substantially all of TARC's assets, other than Inventory, Receivables and
Equipment (collectively, with the assets of the Company, the "Collateral").





                                       15
<PAGE>   23
         There can be no assurance that the Trustee will be able to foreclose
on or dispose of any of the Collateral without substantial delays and other
risks, or that the proceeds obtained therefrom will be sufficient to pay all
amounts owing to holders of the Notes. TransTexas intends to file a shelf
registration statement and any of the Company's other subsidiaries whose stock
is pledged to the Trustee will be required to grant registration rights with
respect to such stock, in each case to allow the Trustee to be able to sell the
pledged shares of their common stock publicly. Circumstances beyond the control
of the Company, however, may delay the availability of a current prospectus.
There is currently no public market for the shares of TARC common stock and
there can be no assurance that there will be any public market for the common
stock of any other subsidiary of the Company. The market prices of the common
stock of the Company's subsidiaries for which there is a public market may be
influenced by many factors, including, among others, investor perception of the
subsidiary, conditions in the subsidiary's industry, fluctuations in quarterly
results, the potential public sale of the shares pledged to secure the Notes
and general economic and market conditions.  In addition, the stock market has
experienced substantial price and volume fluctuations in recent years. These
fluctuations have had a significant effect on the market price of the stock of
many companies, often unrelated to the operating performance of the companies.

         Upon completion of the Capital Improvement Program, management of TARC
estimates that TARC's refinery will have a replacement cost of approximately
$1.4 billion. However, if the Trustee forecloses on the refinery, the proceeds
from the sale of refinery assets may be significantly less than such
replacement cost. Although TARC and its predecessors have previously invested
in excess of $1.1 billion in capital improvements, if the refinery does not
achieve profitable operations, management of TARC estimates that the components
of the refinery, excluding land, would have a liquidation value of only $125
million to $200 million after expenditure of the funds budgeted for completion
of the Capital Improvement Program. Further, TARC may be subject to liability
under applicable Pollution Control Laws (as defined) and Hazardous Substance
Cleanup Laws (as defined). If the Trustee forecloses on the Collateral, it
could incur liability in certain circumstances for the environmental
liabilities of TARC. See "Business of TARC -- Environmental Matters."

         The Collateral will be subject to liens securing certain other
indebtedness and liens arising pursuant to certain other existing or future
obligations may be entitled to priority over the Trustee's lien thereon. See
"-- Lien Priority."

         TARC and TransAmerican are parties to tax benefit transfer ("TBT")
leases relating to certain items of property that are part of the refinery. If,
upon an Event of Default (as defined), the refinery were sold in lieu of
foreclosure and the transferee(s) of those items of property did not agree to
take those items of property subject to the TBT leases, TARC and TransAmerican
would be obligated to indemnify the lessors for the loss of related tax
benefits to the extent provided in the TBT leases. TARC estimates that the
aggregate indemnity obligations under the TBT leases in that event would be
approximately $39 million in September 1997 and would decrease by approximately
$6 million each year thereafter. If the refinery were sold in a
court-supervised foreclosure or transferred as a part of a bankruptcy
proceeding, the lessors could elect to continue the TBT leases in effect for
tax purposes. In that case, the transferee(s) of those items of property might
be required to amortize the purchase price of those items for tax purposes in a
manner that would be less advantageous than if the TBT leases were not deemed
to continue in effect for tax purposes. These adverse tax consequences may
result in a reduced price for the refinery if it were sold.

         In addition, if the Company becomes a debtor in a case under the
United States Bankruptcy Code (the "Bankruptcy Code"), the automatic stay
imposed by the Bankruptcy Code would prevent the Trustee from selling or
otherwise disposing of the Collateral without bankruptcy court authorization.
In that case, the foreclosure might be delayed indefinitely.  Moreover, the
bankruptcy of any entity related to the Company might result in a similar delay
if the Company were "substantively consolidated" with the related entity. See "
- -- Certain Bankruptcy Considerations."

         RISKS RELATED TO FORWARD LOOKING STATEMENTS AND ESTIMATES. This
Prospectus includes "forward-looking statements" as defined in Section 27A of
the Securities Act and Section 21E of the Exchange Act. All statements other
than statements of historical facts included in this Prospectus regarding the
Company's and its subsidiaries' financial positions, business strategies, plans
and objectives of management for future operations and indebtedness covenant
compliance, including but not limited to words such as "anticipates,"
"expects," "estimates," "believes" and "likely,"





                                       16
<PAGE>   24
are forward-looking statements. Management of the Company and its subsidiaries
believe that their current views and expectations are based on reasonable
assumptions; however, there are significant risks and uncertainties that could
significantly affect expected results. Important factors that could cause
actual results to differ materially from those in the forward-looking
statements are disclosed throughout this Prospectus and include, without
limitation, engineering problems, work stoppages, cost overruns, personnel or
materials shortages, fluctuations in the commodity prices for petroleum and
refined products, casualty losses, the success of TransTexas' exploration and
production activities, conditions in the capital markets and competition. The
Company does not intend to update or otherwise revise the forward-looking
statements contained herein to reflect events or circumstances after the date
hereof or to reflect the occurrence of unanticipated events.

         There are numerous uncertainties inherent in estimating quantities of
proved reserves, including many factors beyond the control of TransTexas. The
reserve data included in this Prospectus represent only estimates prepared by
Netherland, Sewell & Associates, Inc. ("Netherland Sewell"). Gas reserve
assessment is a subjective process of estimating the recovery from underground
accumulations of gas that cannot be measured in an exact way, and estimates by
other persons might differ materially from those of Netherland Sewell. Certain
events, including production, acquisitions and future drilling and development
could result in increases or decreases in estimated quantities of proved
reserves. In addition, estimates of TransTexas' future net revenues from proved
reserves and the present value thereof are based on certain assumptions
regarding future natural gas prices, production levels, production and ad
valorem taxes and operating and development costs that may not prove to be
correct over time.

         LIEN PRIORITY. The mortgage securing the TransTexas Intercompany Loan
creates a lien on substantially all of TransTexas' assets, other than
Inventory, Receivables and Equipment, subject to exceptions permitted under the
security documents relating thereto.   The mortgage securing the TARC
Intercompany Loan creates a lien on substantially all of TARC's assets, other
than Inventory, Receivables and Equipment, subject to exceptions permitted
under the security documents relating thereto, including the lien securing any
TARC Notes that remain outstanding after consummation of the TARC Notes Tender
Offer until they are redeemed, repurchased, defeased or repaid.

         Certain types of subsequent encumbrances (such as tax liens,
mechanics' and materialmen's liens, and environmental liens) are entitled to
priority over the liens of the mortgages as a matter of law. The title policy
insuring the lien of the mortgage on the refinery real property contains
exceptions from coverage for these and other matters. See "Business of TARC --
Title Insurance."  The Trustee has entered into an intercreditor agreement with
the trustee under the TARC Notes Indenture that provides among other things
that (i) the TARC Intercompany Loan will be subordinated in right of payment
(except regularly scheduled payments, provided no default under the TARC Notes
Indenture exists or would result therefrom) and lien priority to the TARC
Notes, (ii) (A) in the event of any liquidation or reorganization of TARC, any
cash or other assets paid or distributed on account of the TARC Intercompany
Loan will be applied, after payment of reasonable costs and expenses relating
to obtaining such proceeds, to the payment of the TARC Notes and, only after
the TARC Notes have been paid in full, to the payment of the TARC Intercompany
Loan, and (B) in any other event, any such proceeds will be applied so as not
to impair or affect the right of the holders of the TARC Notes to receive
payments as and when due (but nothing contained in the intercreditor agreement
shall be construed to prohibit, limit or otherwise affect the rights of TARC to
transfer, dispose of or otherwise deal with its properties and assets included
within the Collateral securing both the TARC Notes and the TARC Intercompany
Loan (the "TARC Shared Collateral"), and the proceeds thereof, in any manner
permitted under the TARC Notes Indenture or the security documents relating to
the TARC Intercompany Loan) and (iii) determinations regarding the exercise of
remedies against the TARC Shared Collateral will be made by a majority of the
outstanding principal amount of the TARC Notes and the TARC Intercompany Loan.
It is anticipated that the principal amount of the TARC Intercompany Loan will
remain such that determinations under the intercreditor agreement regarding
enforcement of remedies and dispositions of the TARC Shared Collateral will be
controlled by the Trustee, as the assignee of the TARC Intercompany Loan, and
thus, indirectly, by the holders of the Notes, except that, and the
intercreditor agreement so provides, nothing contained in the intercreditor
agreement will impair or affect the right of the holders of any TARC Notes,
respectively, to institute suit for the enforcement of any payment thereon as
and when due.





                                       17
<PAGE>   25
         The Indenture and the Security Documents (as defined) provide that the
security interest of the Trustee in the Collateral securing the TransTexas
Intercompany Loan will be subordinated to debt or other obligations secured by
(a) pledges of (i) assets or deposits of cash or cash equivalents to secure the
performance of bids, trade contracts (other than borrowed money), leases,
statutory obligations, surety bonds, performance bonds and other obligations of
a like nature in an aggregate amount outstanding at any time not in excess of a
certain percentage of TransTexas' SEC PV10 or (ii) assets, the fair market
value of which is not in excess of $40 million, or deposits of cash or cash
equivalents, in each case, to secure appeal or supersedeas bonds (or to secure
reimbursement obligations or letters of credit in support of such bonds); (b)
Liens encumbering initial deposits and margin deposits securing Swap
Obligations or Permitted Hedging Transactions (each as defined); (c) certain
pledges of assets to secure margin obligations, settlement obligations,
reimbursement obligations or letters of credit in connection with Permitted
Hedging Transactions; (d) encumbrances or title defects on real property which,
in the aggregate, are not material; (e) pledges or deposits in connection with
social security legislation, property insurance and liability insurance; (f)
certain Liens granted in connection with the Presale of Gas (as defined); (g)
certain Liens created on acreage drilled or to be drilled pursuant to Drilling
Programs (as defined), on Hydrocarbons (as defined) produced therefrom and on
the proceeds of such Hydrocarbons to secure TransTexas' obligations thereunder;
(h) Liens securing (i) Royalty Payment Obligations (as defined) and (ii)
Permitted Production Payment Obligations (as defined); (i) Liens that secure
certain Unrestricted Non-Recourse Debt (as defined); and in certain instances
(j) Liens on the proceeds of any property subject to a Permitted TransTexas
Lien or on deposit accounts containing any such proceeds. The Indenture and the
Security Documents further provide that the security interest of the Trustee in
the Collateral securing the TARC Intercompany Loan will be subordinated to debt
or other obligations secured by (a) deposits of cash or Cash Equivalents to
secure (i) the performance of bids, trade contracts (other than borrowed
money), leases, statutory obligations, surety bonds, performance bonds, and
other obligations of a like nature (or to secure reimbursement obligations or
letters of credit issued to secure such performance or other obligations) in an
aggregate amount outstanding at any one time not in excess of $5 million or
(ii) appeal or supersedeas bonds (or to secure reimbursement obligations or
letters of credit in support of such bonds); (b) encumbrances or title defects
on real property which, in the aggregate, are not material; (c) pledges or
deposits made in connection with social security legislation, property
insurance and liability insurance; (d) certain Liens on real or personal
property, acquired after the Issue Date (as defined); (e) non-material leases
or subleases granted to others; (f) certain Liens securing reimbursement
obligations with respect to letters of credit that encumber documents relating
to such letters of credit and the products and proceeds thereof; (g) Liens
encumbering initial deposits and margin deposits securing Swap Obligations or
Permitted Hedging Transactions; (h) Liens on cash deposits to secure
reimbursement obligations with respect to letters of credit after the Delayed
Coking Unit is completed; (i) Liens that secure certain Unrestricted
Non-Recourse Debt; and in certain instances (j) Liens on the proceeds of any
property subject to a Permitted TARC Lien or on deposit accounts containing any
such proceeds. In certain circumstances, the Indenture may require the Trustee
to release Collateral with respect to the foregoing clauses. See "Description
of the Exchange Notes -- Collateral and Security."

         POTENTIAL TAX LIABILITIES.  Part of the refinancing of TransAmerican's
debt in 1993 involved the cancellation of approximately $65.9 million of
accrued interest and of a contingent liability for interest of $102 million
owed by TransAmerican.  TransAmerican has taken the federal tax position that
the entire amount of this debt cancellation is excluded from its income under
the cancellation of indebtedness provisions  (the "COD Exclusion") of the
Internal Revenue Code of 1986, as amended, and has reduced its tax attributes
(including its net operating loss and credit carry forwards) as a consequence
of the COD Exclusion.  No federal tax opinion was rendered with respect to this
transaction, however, and TransAmerican has not obtained a ruling from the
Internal Revenue Service (the "IRS") regarding this transaction.  TransTexas
believes that there is substantial legal authority to support the position that
the COD Exclusion applies to the cancellation of TransAmerican's indebtedness.
However, due to factual and legal uncertainties, there can be no assurance that
the IRS will not challenge this position, or that such challenge would not be
upheld. Under an agreement between TransTexas, TransAmerican and certain of
TransAmerican's subsidiaries (the "Tax Allocation Agreement"), TransTexas has
agreed to pay an amount equal to any federal tax liability (which would be
approximately $25.4 million) attributable to the inapplicability of the COD
Exclusion.  Any such tax would be offset in future years by alternative minimum
tax credits and retained loss and credit carryforwards to the extent
recoverable from TransAmerican.  As a member of the TNGC Consolidated Group
(defined below), each of TransTexas, TEC and TARC will be severally liable for
any tax liability resulting from the above-described transactions.  The IRS has
commenced an audit of the consolidated federal income tax returns of the TNGC
Consolidated Group for its taxable years ended July 31, 1994 and 1995.  Because
the audit is in its initial stages, it is not possible to predict the scope of
the IRS' review or whether any tax deficiencies will be proposed by the IRS as
a result of its review.





                                       18
<PAGE>   26
         Based upon independent legal advice, TransTexas has determined that it
will not report any significant federal income tax liability as a result of the
Lobo Sale.  There are, however, significant uncertainties regarding TransTexas'
tax position and no assurance can be given that TransTexas' position will be
sustained if challenged by the IRS.  TransTexas is part of an affiliated group
for tax purposes (the "TNGC Consolidated Group"), which includes TNGC Holdings
Corporation, the sole stockholder of TransAmerican.  No letter ruling has been
or will be obtained from the IRS regarding the Lobo Sale by any member of the
TNGC Consolidated Group.  If the IRS were to successfully challenge TransTexas'
position, each member of the TNGC Consolidated Group would be severally liable
under the consolidated tax return regulations for the resulting taxes, in the
estimated amount of up to $250 million (assuming the use of existing tax
attributes of the TNGC Consolidated Group), possible penalties equal to 20% of
the amount of the tax, and interest at the statutory rate (currently 9%) on the
tax and penalties (if any).  The Tax Allocation Agreement has been amended so
that TransAmerican is obligated to fund the entire tax deficiency (if any)
resulting from the Lobo Sale.  There can be no assurance that TransAmerican
would be able to fund any such payment at the time due and the other members of
the TNGC Consolidated Group, thus, may be required to pay the tax.  TransTexas
has reserved approximately $75 million with respect to the potential tax
liability for financial reporting purposes to reflect a portion of the federal
tax liability that TransAmerican might not be able to pay.  If TransTexas or
any of the other related companies were required to pay this tax deficiency, it
is likely that it would be required to sell significant assets or raise
additional debt or equity capital to fund the payment.

         DECONSOLIDATION FOR FEDERAL INCOME TAX PURPOSES.  As of September 15,
1997, TEC and TARC, both subsidiaries of TransAmerican, owned approximately
68.9% and 3.4%, respectively, of the outstanding common stock of TransTexas.
These shares are pledged as collateral for TEC's outstanding debt securities.

         Under certain circumstances, TransAmerican, TARC or TEC may sell or
otherwise dispose of shares of  common stock  of  TransTexas.  If, as a result
of any sale or other disposition  of  TransTexas' common stock, the aggregate
ownership of TransTexas by members of the TNGC Consolidated Group (excluding
TransTexas) is less than 80% (measured by voting power and value), TransTexas
will no longer be a member of the TNGC Consolidated Group for federal tax
purposes ("Deconsolidation") and, with certain exceptions, will no longer be
obligated under the terms and conditions of, or entitled to the benefits of,
the Tax Allocation Agreement.   Further, if TEC or TARC sells or otherwise
transfers any stock of TARC, or issues any options, warrants  or  other similar
rights relating to such stock, outside of the TNGC Consolidated Group, which
represents more than 20% of the voting power or equity value of TARC, then a
Deconsolidation of TARC  would occur.   A Deconsolidation of TARC would result
in a Deconsolidation of TransTexas if members of the TNGC Consolidated Group,
excluding TARC, does not then own at least 80% of the voting power and equity
value of TransTexas.  Upon a Deconsolidation of TransTexas, members of the TNGC
Consolidated Group that own TransTexas common stock could incur a substantial
amount of federal income tax liability.  If such Deconsolidation occurred
during the fiscal year ending January 31, 1998, the aggregate amount of this
tax liability is estimated to be between $50 million and $100 million, assuming
no reduction for tax attributes of the TNGC Consolidated Group.  However, such
tax liability generally would be substantially reduced or eliminated in the
event that the IRS successfully challenged TransTexas' position on the Lobo
Sale.  Each member of a consolidated group filing a consolidated federal income
tax return is severally liable to the IRS for the consolidated federal income
tax liability of the consolidated group.  There can be no assurance that each
TNGC Consolidated Group member will have the ability to satisfy any tax
obligation attributable to the foregoing transactions at the time due and,
therefore, other members of the group, including TEC, TransTexas or TARC, may
be required to pay the tax.

         Generally, under the Tax Allocation Agreement, if net operating losses
of TransTexas or TARC are used by other members  of the TNGC Consolidated
Group, then TransTexas and TARC are entitled to the  benefit (through reduced
current taxes payable) of such losses in later years to the extent TransTexas
or TARC has taxable income, remains a member of the TNGC Consolidated Group and
the other group members have the ability to pay such taxes.  If TransAmerican,
TEC or TARC transfers shares of common stock of TransTexas or TARC (or
transfers options or other rights to acquire such shares) and, as a result of
such transfer, Deconsolidation of TransTexas or TARC occurs, TransTexas and
TARC would not thereafter receive any benefit pursuant to the Tax Allocation
Agreement for net operating losses of TransTexas and TARC used by other members
of the TNGC Consolidated Group prior to the Deconsolidation of TransTexas or
TARC.





                                       19
<PAGE>   27
          TransTexas is required, under the Tax Allocation Agreement, to pay
any Texas franchise tax (which is estimated not to exceed $11.4 million)
attributable to prior year transactions.  TransTexas paid approximately $5.4
million of such tax as of the closing of the Lobo Sale and will pay a
substantial amount of the remaining tax within the ensuing 12-month period.

         POTENTIAL EFFECTS OF A CHANGE OF CONTROL.  The TransTexas Subordinated
Notes Indenture provides that, upon the occurrence of a change of control (as
defined therein), each holder of the TransTexas Subordinated Notes will have
the right to require TransTexas to repurchase such holder's notes at 101% of
the principal amount thereof plus accrued and unpaid interest.  Pursuant to the
terms of the Intercompany Loans, upon the occurrence of a change of control,
TEC would have the right to require TransTexas and TARC to repay the principal
of the TransTexas Intercompany Loan in an amount equal to a pro rata share of
the amount TEC is required to pay under the Indenture.  Such pro rata share
would be calculated using the ratio of the outstanding principal amount of the
TransTexas Intercompany Loan (or, for TARC, the accreted value of the
outstanding principal amount of the TARC Intercompany Loan) to the sum of (i)
the outstanding principal amount of the TransTexas Intercompany Loan plus (ii)
the accreted value of the outstanding principal amount of the TARC Intercompany
Loan.  A change of control would be deemed to occur under the TransTexas
Subordinated Notes Indenture in the case of certain changes or other events in
respect of the ownership of TransTexas, including any circumstances pursuant to
which any person or group other than John R. Stanley (or his heirs, his estate
or any trust in which he or his immediate family members have, directly or
indirectly, a beneficial interest in excess of 50%) and his subsidiaries or the
Trustee is or become the beneficial owner of more than 50% of the total voting
power of TransTexas' then outstanding voting stock and during the 90-day period
thereafter the rating on the notes is downgraded or withdrawn.  A change of
control would be deemed to occur under the Indenture and the Intercompany Loans
in the case of certain changes or other events in respect of the ownership or
control of TEC, TransTexas, or TARC including any circumstance pursuant to
which (i) any person or group, other than John R. Stanley (or his heirs, his
estate or any trust in which he or his immediate family members have, directly
or indirectly, a beneficial interest in excess of 50%) and  his  subsidiaries
or the Trustee is or becomes the beneficial owner of more than 50% of the total
voting power of TEC's then outstanding voting stock or (ii) TEC or any of its
subsidiaries own some of TransTexas' or TARC's capital stock, respectively, but
less than 50% of the total voting stock or economic value of TransTexas or
TARC, respectively, unless the Notes have an investment grade rating for the
period of 120 days thereafter.  The term "person," as used in the definition of
change of control, means a natural person, company, government or political
subdivision, agency or instrumentality of a government and also includes a
"group," which is defined as two or more persons acting as a partnership,
limited partnership or other group.  In addition, certain changes or other
events in respect of the ownership or control of TransTexas that do not
constitute a "change of control" under the TransTexas Subordinated Notes
Indenture or the Indenture may result in a "change of control" of TransTexas
under the terms of TransTexas' credit facility (the "BNY Facility") and certain
equipment financing.  Such an occurrence could create an obligation for
TransTexas to repay such other indebtedness.  At July 31, 1997, TransTexas had
approximately $26.6 million of indebtedness (excluding the TransTexas
Intercompany Loan and the TransTexas Subordinated Notes) subject to such right
of repayment or repurchase.  In the event of a change of control under the
Indenture or a "change of control" under the terms of the TransTexas
Subordinated Notes Indenture or other outstanding indebtedness, there can be no
assurance that TransTexas or TARC will have sufficient funds to satisfy any
such payment obligations.

         A change of control or other event that results in Deconsolidation of
TransTexas and TransAmerican for federal income tax purposes could result in
acceleration of a substantial amount of federal income taxes.  See
"--Deconsolidation for Federal Income Tax Purposes."

         ORIGINAL ISSUE DISCOUNT. The Senior Secured Discount Exchange Notes
will be issued with original issue discount for federal income tax purposes
("OID"). Consequently, holders of the Senior Secured Discount Exchange Notes
generally will be required to include OID over the period commencing on the
issuance of the Senior Secured Discount Exchange Notes until June 15, 1999 that
they hold the Senior Secured Discount Notes in ordinary income for federal
income tax purposes in advance of the receipt of the cash attributable thereto.
See "Certain Federal Income Tax Considerations" for a more detailed discussion
of the federal income tax consequences of the purchase, ownership and
disposition of the Senior Secured Discount Notes.





                                       20
<PAGE>   28
         If a bankruptcy case is commenced by or against the Company under the
Bankruptcy Code after the issuance of the Senior Secured Discount Notes, the
claim of a holder of Senior Secured Discount Notes with respect to the
principal amount thereof may be limited to an amount equal to the sum of (i)
the initial offering price and (ii) that portion of the OID (if any) that is
deemed not to constitute "unmatured interest" for purposes of the Bankruptcy
Code. Any OID that was not amortized as of any such bankruptcy filing would
constitute "unmatured interest."

         CERTAIN BANKRUPTCY CONSIDERATIONS. An investment in the Exchange Notes
involves certain risks in the event that the Company or any of its related
entities becomes the debtor in a case under the Bankruptcy Code, including
substantive consolidation and fraudulent transfer risks, as well as risks
discussed elsewhere herein. If any of John R. Stanley, TNGC, TransAmerican,
TransTexas, TARC, TTXD or any other related entity becomes a debtor in a case
under the Bankruptcy Code, and if the bankruptcy court enters an order
"substantively consolidating" the Company, TransTexas or TARC and the debtor in
that case, payment of the Notes could be delayed or impaired. In a substantive
consolidation, the assets and liabilities of the affected entities are
combined, so that the creditors of all entities share in the consolidated pool
of assets. Such a consolidation would expose the holders of the Notes not only
to the usual impairments resulting from bankruptcy, such as a stay of the
Trustee's right to foreclose, but also to potential dilution of the amount
recoverable because of the larger creditor base. See "-- Adequacy of
Collateral; Risks of Foreclosure" and "-- Original Issue Discount."

         It should be noted that TransAmerican and its affiliates filed a
voluntary bankruptcy petition in 1975 and began operating pursuant to a
confirmed plan of reorganization in May 1980. TransAmerican filed a voluntary
bankruptcy petition again in 1983 and emerged from bankruptcy in 1987. In both
of those cases, TransAmerican's creditors received less than the amounts to
which they were otherwise entitled.

         FRAUDULENT TRANSFER CONSIDERATIONS. The Company's obligations under
the Notes, TransTexas' obligations under the TransTexas Intercompany Loan,
TARC's obligations under the TARC Intercompany Loan, the security interests in
TransTexas' assets and TARC's assets to secure the TransTexas Intercompany Loan
and the TARC Intercompany Loan, respectively, and the obligations of any future
subsidiary of TransTexas or TARC as guarantors of the TransTexas Intercompany
Loan and the TARC Intercompany Loan, respectively, may in each case be subject
to review under state or federal fraudulent transfer laws in the event of the
bankruptcy or other financial difficulty of the Company, TransTexas, TARC or
any future subsidiary of TransTexas or TARC. The Company believes that the
Transactions will not constitute a fraudulent transfer; however, there can be
no assurance that a court would reach a similar conclusion.

         Under those laws, if a court, in a lawsuit by an unpaid creditor or
representative of creditors of a debtor, such as a trustee in bankruptcy or the
debtor as a Chapter 11 debtor in possession, were to find that at the time of a
transfer by the debtor (including the grant of a security interest in the
debtor's assets) or the incurrence of an obligation by the debtor, such debtor
(1) made the transfer or incurred the obligation with actual intent to hinder,
delay or defraud creditors or (2) (a) received less than fair consideration or
reasonably equivalent value for the transfer or the incurrence of the
obligation and (b) either (i) was or was rendered insolvent, (ii) was engaged
in a business or transaction for which its remaining unencumbered assets
constituted unreasonably small capital or (iii) intended to incur or believed
that it would incur debts beyond its ability to pay such debts as they mature,
the court could avoid the transfer or the obligation, as the case may be. In
the event of an avoided obligation, the court could direct the return of any
amounts paid thereunder to the debtor or to a fund for the benefit of its
creditors.

         A court is likely to hold that an obligor did not receive fair
consideration or reasonably equivalent value to the extent that the proceeds of
its borrowing were distributed by dividend or otherwise to its shareholders.
Thus, the Company will likely be deemed not to have received reasonably
equivalent value for its obligations under the Notes to the extent that the
proceeds were used for the TEC Preferred Stock Redemption. Similarly, a court
may hold that TransTexas did not receive reasonably equivalent value for its
obligations under the TransTexas Intercompany Loan to the extent that the
proceeds thereof are deemed to have been used in the Share Repurchase Program.





                                       21
<PAGE>   29
         The measure of insolvency for purposes of the foregoing will vary
depending on the law of the jurisdiction being applied. Generally, however, an
entity would be considered insolvent if the sum of its debts (including
contingent or unliquidated debts) is greater than all of its property at a fair
valuation or if the present fair salable value of its assets is less than the
amount that will be required to pay its probable liability on its existing
debts as they become absolute and matured.

         If a court found that at the time of the Transactions, clause (1) or
(2) above applied to the Company's obligations under the Notes, to TransTexas'
or TARC's respective obligations under the TransTexas Intercompany Loan or the
TARC Intercompany Loan, to the grant of the security interests securing the
TransTexas Intercompany Loan and the TARC Intercompany Loan, or to the
obligations of any guarantor of the TransTexas Intercompany Loan or the TARC
Intercompany Loan, the court could avoid the obligations or the grant of the
security interest, as the case may be.

         The liability of any future subsidiary of TransTexas and TARC under
their respective guarantees of the TransTexas Intercompany Loan and the TARC
Intercompany Loan will in each case be limited to the guarantor's "Adjusted Net
Assets," the maximum amount that the guarantor could pay without (among other
things) becoming insolvent. This limitation is intended to protect the
guarantees from avoidance as fraudulent transfers, although there can be no
assurance that it will successfully do so. There can also be no assurance that
such limited amounts will suffice to pay amounts owed under the Intercompany
Loans in full. As explained above, if any guarantor pays any amount under its
guarantee for the benefit of the holders of the Notes, and if a court
thereafter finds that the payment exceeded the guarantee's maximum amount, the
court could direct that the payment be repaid to the guarantor or to a fund for
the benefit of its creditors.

         CONTROL BY SOLE STOCKHOLDER; POTENTIAL CONFLICTS OF INTEREST.
TransAmerican is the sole holder of common stock of the Company. As a member of
the board of directors and chief executive officer of TransAmerican, the
Company, TransTexas and TARC, and sole stockholder, chairman of the board and
chief executive officer of TNGC, John R. Stanley is in a position to control or
significantly influence the management and operations of the Company,
TransTexas and TARC, including actions with respect to pending and future
litigation. The directors generally will have fiduciary obligations to
TransAmerican, the sole holder of common stock of the Company, and not to the
holders of the Notes. There can be no assurance that conflicts will not arise
between TNGC, TransAmerican, the Company, TransTexas, TARC, Mr. Stanley in his
various capacities and the holders of the Notes. In addition, Mr. Stanley has
guaranteed certain indemnity obligations of TransAmerican and TransTexas and
certain debt of TransTexas. The Company's, TransTexas' or TARC's response to
any litigation or any indemnification demand may be influenced by TransAmerican
or Mr. Stanley in a manner that could be adverse to the holders of the Notes.

         TNGC, TransAmerican and its existing subsidiaries, including the
Company, TransTexas and TARC, are parties to a tax allocation agreement, the
general terms of which will provide for TNGC and all of its subsidiaries to
file federal income tax returns as members of a consolidated group. The tax
allocation agreement requires the Company, TransTexas and TARC to make certain
payments to TNGC to enable TNGC to pay its federal or alternative minimum tax.
In the event of an IRS audit or examination, the tax allocation agreement gives
TNGC the authority to compromise or settle disputes and to control litigation,
subject to the approval of the Company, TransTexas or TARC, as the case may be,
where such compromise or settlement affects the determination of the separate
tax liability of that company. See "Certain Relationships and Related
Transactions."

         MATERIAL PROCEEDINGS. TransTexas and TARC have been and continue to be
involved in a number of legal proceedings. The adverse resolution in any
reporting period of one or more of any such matters could have a material
adverse impact on the results of operations of TransTexas or TARC and the
Company for that period. See "Business of TransTexas -- Legal Proceedings" and
"Business of TARC -- Legal Proceedings."

         ABSENCE OF PUBLIC MARKET FOR THE NOTES. The Outstanding Notes have not
been registered under the Securities Act, are subject to significant
restrictions on resale and have no established trading markets. The Company
does not intend to apply for listing of the Outstanding Notes or the Exchange
Notes on any securities exchange or to seek the admission thereof to trading in
The Nasdaq Stock Market.  The Initial Purchaser has informed the Company that
it currently intends to make a market in the Exchange Notes.  However, it is
not so obligated, and any such market making may be discontinued at any time
without notice.  In addition, such market making activity will be subject to
the limits imposed by the Securities Act and the Exchange Act and may be
limited during the Exchange Offer or the pendency of the Shelf Registration
Statement.  See "Description of the Exchange Notes -- Registration Rights."  
Accordingly, no assurance can be given that an active public or other market 
will develop for the Exchange Notes.

         If a market for the Exchange Notes does not develop, purchasers may
not be able to resell any of the Notes for an extended period of time, if at
all. If a market for the Exchange Notes does develop, the Exchange Notes may
trade at a discount from their initial offering price, depending upon
prevailing interest rates, results of operations of TransTexas or TARC, the
market for similar securities and other factors. There can be no assurance that
a holder of Notes will be able to sell such securities in the future or that
such sale will be at a price equal to or greater than the initial offering
price of the Outstanding Notes.

         EXCHANGE OFFER PROCEDURES.  Issuance of the Exchange Notes in exchange
for Outstanding Notes pursuant to the Exchange Offer will be made only after
timely receipt by the Company of such Outstanding Notes, a properly completed
and duly executed Letter of Transmittal and all other required documents.
Therefore, holders of the Outstanding Notes desiring to tender such Outstanding
Notes in exchange for Exchange Notes should allow sufficient time to ensure
timely delivery.  The Company is under no duty to give notification of defects
or irregularities with respect to the tenders of Outstanding Notes for
exchange.  Outstanding Notes that are not tendered or are tendered but not
accepted will, following the consummation of the Exchange Offer, continue to be
subject to the existing restrictions upon transfer thereof.  Upon consummation
of the Exchange Offer, the registration rights under the Registration Rights
Agreement will terminate except that if any holder notifies the Company within
six months of consummation of the Exchange Offer that (i) due to a change in
law or policy it was not entitled to participate in the Exchange Offer or (ii)
such holder received Exchange Notes that may not be sold without material
restriction under state and federal securities laws, then the Company has
agreed to file and maintain for a period of two years the Shelf Registration
Statement.  The Company has also agreed to file and maintain a Shelf
Registration Statement after consummation of a Private Exchange, if the Initial
Purchaser so requests within one year after the closing of the TEC Notes
Offering.  In addition, any holder of Outstanding Notes who tenders in the
Exchange Offer for the purpose of participating in a distribution of the
Exchange Notes may be deemed to have received restricted securities and, if so,
will be required to comply with the registration and prospectus delivery
requirements of the Securities Act in connection with any resale transaction.
Each broker-dealer that receives Exchange Notes for its own account in exchange
for Outstanding Notes, where such Outstanding Notes were acquired by such
broker-dealer as a result of market-making activities or other trading
activities, must acknowledge that it will deliver a prospectus in connection
with any resale of such Exchange Notes.  See "Plan of Distribution."  To the
extent that Outstanding Notes are tendered and accepted in the Exchange Offer,
the trading market for untendered and tendered but unaccepted Outstanding Notes
could be adversely affected.  See "The Exchange Offer."

RISK FACTORS RELATED TO TRANSTEXAS

         SUBSTANTIAL CAPITAL REQUIREMENTS. TransTexas makes substantial capital
expenditures for the exploration, development and production of its natural gas
reserves.  Historically, TransTexas has financed capital expenditures and
serviced its debt with cash from operations, public and private offerings of
debt and equity securities, the sale of production payments, asset sales and
other financings. TransTexas intends to use cash flow from operations, together
with the proceeds it received pursuant to the Transactions, to fund its cash
requirements in fiscal 1998. If capital expenditures are higher than
anticipated, cash flow from operations is lower than anticipated or certain
contingent obligations of TransTexas become fixed, TransTexas may not have
sufficient funds for capital expenditures necessary to replace its reserves, to
maintain production at current levels or to attain increased production levels
and, as a result, production from operations may decrease over time. No
assurance can be given that TransTexas' cash flow from





                                       23
<PAGE>   31
operating activities will be sufficient to meet actual capital expenditures,
contingent liabilities and debt service in the future.  TransTexas anticipates
that it will be required to supplement its cash flow from operations with asset
sales or other financings in order to meet its capital expenditure requirements
for fiscal 1998, although no assurance can be given that such sources of
capital will be available.

         LIMITED OPERATING HISTORY IN CONTINUING OPERATIONS. Prior to the Lobo
Sale, TransTexas derived a substantial amount of its revenues from gas produced
from its Lobo Trend producing properties. TransTexas' experience in the
drilling and operation of wells in areas outside of the Lobo Trend is limited,
its completion rate in such areas is substantially lower and its average
lifting costs in such areas are higher. Accordingly, results of operations from
the Continuing Operations or from properties acquired in the future might
differ materially from those in the Lobo Trend.

         ABILITY TO REPLACE SHORT-LIVED RESERVES. TransTexas' principal
producing properties are characterized by high initial production followed by a
steep decline in production rates, with wells typically having a half-life of
less than two years and an economic life of approximately ten years. As a
result, TransTexas must find and develop or acquire new natural gas reserves to
replace those being depleted by production. Without successful drilling and
exploration or acquisition activities, TransTexas' reserves and production will
decline rapidly. TransTexas' business strategy is to add reserves by pursuing
an active drilling program on its existing undeveloped properties and on
properties that it may acquire in the future. There can be no assurance that
production from new wells will be sufficient to replace production from
existing wells.

         NATURAL GAS PRICE FLUCTUATIONS AND MARKETS. TransTexas' results of
operations and the value of its gas and oil properties are highly dependent
upon the prices TransTexas receives for its natural gas. Substantially all of
TransTexas' sales of natural gas are made in the spot market, or pursuant to
contracts based on spot market prices, and not pursuant to long-term,
fixed-price contracts. Accordingly, the prices received by TransTexas for its
natural gas production are dependent upon numerous factors beyond the control
of TransTexas, including the level of consumer product demand, the North
American supply of natural gas, government regulations and taxes, the price and
availability of alternative fuels, the level of foreign imports of oil and
natural gas, and the overall economic environment. Demand for natural gas is
seasonal, with demand typically higher during the summer and winter, and lower
during the spring and fall, with concomitant changes in price. During the
quarter ended July 31, 1997, the average gas price for the Continuing
Operations was $2.04 per Mcf.

         Any significant decline in current prices for natural gas could have a
material adverse effect on TransTexas' financial condition, results of
operations and quantities of reserves recoverable on an economic basis. In
order to mitigate its vulnerability to natural gas price volatility, TransTexas
has entered into and may continue to enter into commodity price swap agreements
to reduce its exposure to price risk in the spot market for natural gas. See
"Business of TransTexas -- Hedging." However, all of TransTexas' current
production remains subject to natural gas price fluctuations. Based on an
assumed average daily net production level of 230 MMcfd (after giving effect to
the Lobo Sale), TransTexas estimates that a $0.10 per MMBtu change in average
gas prices received would change annual operating income by approximately $6.4
million.

         COMPETITION. TransTexas competes in the highly competitive areas of
natural gas exploration, development and production. Many of TransTexas'
competitors have substantially larger financial resources, staffs and
facilities than TransTexas.

         DRILLING RISKS. Drilling activities are subject to numerous risks,
including mechanical risk and the risk that no commercially productive
reservoirs will be encountered. There can be no assurance that new wells
drilled by TransTexas will be productive or that TransTexas will recover all or
any portion of its investment. The cost of drilling, completing and operating
wells is often uncertain. TransTexas' drilling operations may be curtailed,
delayed or canceled as a result of numerous factors, many of which are beyond
TransTexas' control, including title problems, weather conditions, compliance
with governmental requirements and shortages or delays in the delivery of
equipment and services.





                                       24
<PAGE>   32
         TRANSPORTATION. As a result of the Lobo Sale, TransTexas no longer
owns the pipeline assets held by TTC, which assets are used to transport
natural gas from certain of the Continuing Operations. Although TransTexas has
entered into a transportation agreement to provide it access to such pipeline,
there can be no assurance that this agreement will provide sufficient access or
capacity or that the terms thereof will remain competitive with market rates.

         RISKS RELATED TO LOBO SALE. The Lobo Sale Agreement contains
representations and warranties by TransTexas typical for the sale of an oil and
gas exploration, production and transmission company, including the following:
representations and warranties relating to the accuracy of financial
information; liabilities under employee benefit plans; payment of taxes;
existence of litigation or other claims; compliance with laws, including
environmental laws; condition of personal property; existence of contracts,
commitments and contingent liabilities; and title to properties.  TransTexas
has indemnified the buyer for certain liabilities related to the assets of TTC,
including judgment liens, costs to remediate conditions that may result in
environmental liability and liabilities and costs related to inaccuracies in
representations and warranties (without regard to TransTexas' knowledge of such
inaccuracy) with respect to which no purchase price adjustment was made at the
closing or as part of the post-closing reconciliation. TransTexas does not
anticipate that it will be responsible for any material amount of post-closing
indemnity obligations under the Lobo Sale Agreement, but there can be no
assurance that such liabilities will not significantly reduce the benefits to
be obtained by TransTexas from the Lobo Sale.

         OPERATING HAZARDS AND UNINSURED RISKS. TransTexas' operations are
subject to hazards and risks inherent in drilling for, and the production,
processing and transportation of, natural gas, such as fires, explosions,
encountering formations with abnormal pressures, blowouts, cratering, pipeline
ruptures and spills, any of which can result in loss of hydrocarbons,
environmental pollution, personal injury claims and other damage to properties
of TransTexas and others. TransTexas' insurance coverage includes, among other
things, operator's extra expense, physical damage on certain assets, employer's
liability, comprehensive general liability, automobile and workers'
compensation insurance.  TransTexas believes that its insurance is adequate and
customary for companies of a similar size engaged in operations similar to
those of TransTexas, but losses can occur for uninsurable or uninsured risks or
in amounts in excess of existing insurance coverage.

         GOVERNMENT REGULATIONS. TransTexas' business is subject to certain
federal, state and local laws and regulations relating to the exploration for
and the development, production and transportation of natural gas, as well as
environmental and safety matters. Many of these laws and regulations have
become more stringent in recent years, often imposing greater liability on a
larger number of potentially responsible parties. Because the requirements
imposed by such laws and regulations are frequently changed, TransTexas is
unable to predict the ultimate cost of compliance with these requirements or
their effect on its operations. See "Business of TransTexas -- Environmental
Matters."

RISK FACTORS RELATED TO TARC

         LIMITED OPERATING HISTORY. TARC has a limited operating history.
TARC's predecessor and indirect parent corporation, TransAmerican, acquired the
refining facility in 1971 and, between 1978 and 1983, invested approximately
$900 million in capital improvements to expand capacity and increase refining
complexity. The refinery operated at a loss in fiscal 1981 and 1982, and in
January 1983, financial difficulties prevented TransAmerican from completing
certain units of the refinery and forced a shutdown of operations. See "--
General Risk Factors -- Certain Bankruptcy Considerations." TARC recommenced
partial operations at the refinery in March 1994 and has operated the No. 2
Vacuum Unit intermittently since that time. TARC has incurred losses and
negative cash flows from operating activities as a result of limited refining
operations that did not cover the fixed costs of operating the refinery,
increased working capital requirements and losses on refined product sales due
to financing costs and low operating margins. TARC intends to commence
operation of the Delayed Coking Unit and certain supporting units once they are
mechanically complete. In addition, subject to certain exceptions, TARC could
operate the No. 2 Crude Unit and/or the No. 2 Vacuum Unit for a third party as
part of a processing arrangement that TARC reasonably believes will provide a
positive contribution to operating profit after recovering all direct operating
costs. TARC's decision to commence or suspend operations will be based on the
availability of financing, current operating margins and the need to tie-in
units as they are completed. No assurance can be given that such operations
prior to completion of Phase I will not generate losses and negative cash flow,
that the projections contained herein will prove accurate or that TARC will
ultimately achieve profitable operations at the refinery.





                                       25
<PAGE>   33
         CAPITAL IMPROVEMENT PROGRAM REQUIREMENTS; CONSTRUCTION RISKS. Major
construction projects, such as the Capital Improvement Program, entail
significant risks, including possible unanticipated shortages of materials or
skilled labor, unforeseen engineering or environmental problems, work
stoppages, weather interference, unanticipated cost increases and regulatory
problems. Adverse developments in any of these areas could delay the project or
increase its costs.  Expenditures necessary to complete the Capital Improvement
Program are budgeted at approximately $427 million. The Transactions are
expected to fully fund the budget for the Capital Improvement Program. If
engineering problems, cost overruns or delays occur, TARC may not be able to
complete the entire Capital Improvement Program without cash provided from
operations or the incurrence of additional indebtedness. Although TARC expects
to have a credit facility to meet its working capital needs in place by the
completion of Phase I, TARC currently does not have such facility in place.
See "Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Liquidity and Capital Resources."

         TARC has engaged a number of specialty consultants and engineering and
construction firms to assist it in completing the individual projects that
comprise the Capital Improvement Program. However, TARC will act as the general
contractor for the Capital Improvement Program, and TARC or one of its
affiliates will construct certain portions of the facilities. TARC's
predecessor commenced two major construction projects in the 1970s, one of
which involved the refinery, neither of which was completed. In addition,
expenditures incurred in connection with the construction and expansion program
begun in February 1995 substantially exceeded the budget therefor, partially
because of changes in the scope of such program.

         VOLATILITY OF GROSS REFINING MARGINS; CURRENT MARKET CONDITIONS.
TARC's income and cash flow will be derived from the difference between its
costs to obtain and refine crude oil and other feedstocks and the price for
which it can sell its refined products. TARC will buy crude oil and other
feedstocks and sell refined petroleum products on the spot market. TARC will
maintain inventories of crude oil, other feedstocks, intermediate products and
refined products, the values of which are subject to fluctuations in market
prices. Factors that are beyond the control of TARC may cause the cost of crude
oil and other feedstocks purchased by TARC and the price of refined products
sold by TARC to fluctuate widely. Although prices of crude oil and refined
petroleum products generally move in the same direction, prices of refined
products often do not respond immediately to changes in crude oil costs. An
increase in market prices for crude oil and other feedstocks, or a decrease in
market prices for refined products, could have an adverse impact on TARC's
income and cash flow.

         In order to manage its exposure to price risks in the marketing of its
refined products, TARC expects to enter into fixed price delivery contracts,
financial swaps and futures contracts as hedging devices. To ensure a fixed
price for its products, TARC may sell a futures contract and thereafter either
(i) make physical delivery of its product to comply with such contract or (ii)
buy a matching futures contract to unwind its futures position and sell its
products to a customer. Such contracts may restrict the ability of TARC to
benefit from unexpected increases in refined product prices. Hedging by TARC
has in the past resulted in financial losses and may in the future expose TARC
to the risk of financial loss in certain circumstances. There can be no
assurance that hedging devices utilized by TARC will protect against its
exposure to price risk.

         DEPENDENCE ON SINGLE SITE OF OPERATIONS. All of TARC's refining
activities are conducted at one location. The refining operations are subject
to inherent risks including fires, floods, accidents, explosions and chemical
releases into the air and water. As a result, the operations of TARC could be
subject to significant interruption if the refinery or the pipelines that it
utilizes were to experience a fire, flood, major accident, shutdown or
equipment failure, or if it were damaged by severe weather or other natural
disaster. Although TARC expects to have sufficient insurance at all times,
there can be no assurance that TARC can obtain increased coverage amounts in
the future at rates or on terms it considers reasonable or acceptable or that
all losses from business interruption and damages or liability for an accident
will be covered by insurance. The occurrence of significant events against
which TARC is not fully insured or of a number of lesser events against which
TARC is fully insured but subject to substantial deductibles could materially
and adversely affect TARC's operations and financial condition. See "Business
of TARC -- Insurance." In addition, the refinery will receive substantially all
of its crude oil and other feedstocks at its dock on the Mississippi River. The
weather or any obstruction of the river could interrupt supplies of crude oil
feedstock, shipments of refined products or otherwise materially affect
operations.





                                       26
<PAGE>   34
         COMPETITION.  The industry in which TARC operates is highly
competitive.  Since the United States imports significant quantities of refined
petroleum products, TARC views offshore refiners as its primary competition.
However, TARC also competes with refiners in the Gulf Coast region, many of
which are owned by large, integrated oil companies that because of their more
diverse operations, stronger capitalizations or crude oil supply arrangements,
are better able than TARC to withstand volatile industry conditions, including
shortages or excesses of crude oil or refined products or intense price
competition. The principal competitive factors affecting TARC's refining
operations are the quality, quantity and delivered costs of crude oil and other
refinery feedstocks, refinery processing efficiency, mix of refined products,
refined product prices and the cost of delivering refined products to markets.
Competition also exists between the petroleum refining industry and other
industries supplying energy and fuel to industrial, commercial and individual
consumers.  See "Business of TARC -- Competition."

         ENVIRONMENTAL MATTERS

         COMPLIANCE MATTERS. TARC is subject to federal, state and local laws,
regulations and ordinances ("Pollution Control Laws"), which regulate
activities such as discharges to air and water, as well as handling and
disposal practices for solid and hazardous wastes. TARC believes that it is in
substantial compliance with applicable Pollution Control Laws. However, newly
enacted Pollution Control Laws, as well as increasingly strict enforcement of
existing Pollution Control Laws, may require TARC to make additional capital
expenditures in order to comply with such laws and regulations. To ensure
continuing compliance, TARC has made environmental compliance and permitting
issues an integral part of its refinery's start-up plans and has budgeted for
such capital expenditures in the Capital Improvement Program.

         TARC uses (and in the past has used) certain materials, and generates
(and in the past has generated) certain substances or wastes that are or may be
deemed hazardous substances or wastes. In the past, the refinery has been the
subject of certain environmental enforcement actions, and incurred certain
fines, as a result of certain of TARC's operations. TARC also was previously
subject to enforcement proceedings relating to its prior production of leaded
gasoline and air emissions. TARC believes that, with minor exception, all of
these past matters were resolved prior to or in connection with the resolution
of the bankruptcy proceedings of its predecessor in interest, TransAmerican, or
are no longer applicable to TARC's operations. As a result, TARC believes that
such matters will not have a material adverse effect on TARC's future results
of operations, cash flow or financial position.

         REQUIREMENTS UNDER THE FEDERAL CLEAN AIR ACT. The National Emission
Standards for Hazardous Air Pollutants for Benzene Waste Operations (the
"Benzene Waste NESHAPS"), promulgated in January 1993 pursuant to the Clean Air
Act, regulate benzene emissions from numerous industries, including petroleum
refineries. The Benzene Waste NESHAPS require all existing, new, modified, or
reconstructed sources to reduce benzene emissions to a level that will provide
an ample margin of safety to protect public health. TARC will be required to
comply with the Benzene Waste NESHAPS as its refinery operations start up. TARC
believes that compliance with the Benzene Waste NESHAPS will not have a
material adverse effect on TARC's financial position, results of operations or
cash flows.  Until the refinery is in full operation, however, there can be no
assurance that the regulations will not have such an effect.

         In addition, the Environmental Protection Agency ("EPA") promulgated
National Emission Standards for Hazardous Air Pollutants for Hazardous Organics
(the "Hazardous Organics NESHAPS") regulations for petroleum refineries under
the Clean Air Act in 1995, and subsequently has amended such regulations. These
regulations set "Maximum Achievable Control Technology" ("MACT") standards for
petroleum refineries. The Louisiana Department of Environmental Quality (the
"LDEQ") has incorporated MACT standards into TARC's air permits under federal
and state air pollution prevention laws. TARC believes that compliance with the
Hazardous Organics NESHAPS will not have a material adverse effect on TARC's
financial position, results of operations or cash flow.  Until the refinery is
in full operation, however, there can be no assurance that the regulations will
not have such an effect.





                                       27
<PAGE>   35
         The EPA recently promulgated federal regulations pursuant to the Clean
Air Act to control fuels and fuel additives (the "Gasoline Standards") that
could have a material adverse effect on TARC. Under these regulations, only
reformulated gasoline can be sold in certain domestic geographic areas in which
the EPA has mandated or approved its use. Reformulated gasoline must contain a
minimum amount of oxygen, have a lower vapor pressure, and have reduced sulfur,
olefins, benzene and aromatics compared to the average 1990 gasoline. The EPA
recently promulgated final National Ambient Air Quality Standards ("NAAQS") that
revise the standards for particulate matter and ozone. The number and extent of
the areas subject to reformulated gasoline standards may increase in the future
after the NAAQS are implemented. Conventional gasoline may be used in all other
domestic markets; however, a refiner's post-1994 average conventional gasoline
must not be more polluting than it was in 1990. With limited exceptions, to
determine its compliance as of January 1, 1995, a refiner must compare its
post-1994 and 1990 average values of controlled fuel parameters and emissions.
The Gasoline Standards recognize that many gasoline refiners may not be able to
develop an individual 1990 baseline for a number of reasons, including, for
example, lack of adequate data or the absence or limited scope of operations in
1990. Under such circumstances, the refiner must use a statutory baseline
reflecting the 1990 industry average. The EPA has authority, upon a showing of
extenuating circumstances by a refiner, to grant an individual adjusted baseline
or other appropriate regulatory relief to that refiner.

         TARC filed a petition with the EPA requesting an individual baseline
adjustment or other appropriate regulatory relief based on extenuating
circumstances. The extenuating circumstances upon which TARC relied in its
petition include the fact that the refinery was not in operation in 1990 (and
thus there is no 1990 average for purposes of the necessary comparison) and the
fact that the start-up of the refinery is to occur on a phased-in basis. The
EPA has denied TARC's request for an individual baseline adjustment and other
regulatory relief. TARC will continue to pursue regulatory relief with the EPA.
There can be no assurance that any action taken by the EPA will not have a
material adverse effect on TARC's future results of operations, cash flows or
financial position.

         Title V of the Clean Air Act requires states to implement an Operating
Permit Program that codifies all federally enforceable limitations that are
applicable to a particular source. The EPA has approved Louisiana's Title V
Operating Permit Program. The deadline for a refinery to submit an Operating
Permit Application under the Louisiana program was October 12, 1996. TARC
timely submitted its Title V Operating Permit application and the LDEQ has
designated the application as being administratively complete. As yet, the LDEQ
has not responded further regarding the status of TARC's Title V Operating
Permit. TARC believes that its application will be approved. However, there can
be no assurance that it will be approved as submitted or that additional
expenditures required pursuant to Title V Operating Permit obligations will not
have a material adverse effect on TARC's financial position, results of
operations or cash flow.

         CLEANUP MATTERS. TARC also is subject to federal, state and local
laws, regulations and ordinances that impose liability for the costs of clean
up relating to, and certain damages resulting from, past spills, disposals or
other releases of hazardous substances ("Hazardous Substance Cleanup Laws").
Over the past several years, TARC has been, and to a limited extent continues
to be, engaged in environmental cleanup or remedial work relating to or arising
out of operations or activities at the refinery. In addition, TARC has been
engaged in upgrading its solid waste facilities, including the closure of
several waste management units. Similar to numerous other industrial sites in
the state, the refinery has been listed by the LDEQ on the Federal
Comprehensive Environmental Response, Compensation and Liability Information
System, as a result of TARC's prior waste management activities (as discussed
below).

         In 1991, the EPA performed a facility assessment at TARC's refinery
pursuant to the Federal Resource Conservation and Recovery Act ("RCRA"). The
EPA performed a follow up assessment in March 1996, but has not yet issued a
report of its investigations. In July 1996, the EPA and the LDEQ agreed that
the LDEQ would serve as the lead agency with respect to the investigation and
remediation of areas of concern identified in the investigations. TARC, under a
voluntary initiative approved by the LDEQ, has submitted a work plan to the
LDEQ to determine which areas may require further investigation and
remediation. The LDEQ has not yet responded to TARC's submission or issued any
further requests relating to this matter. As a result, TARC is unable at this
time to estimate what the costs, if any, will be if the LDEQ does require
further investigation or remediation of the areas identified.





                                       28
<PAGE>   36
         TARC has been identified as a potentially responsible party ("PRP")
under the Comprehensive Environmental Response, Compensation, and Liability Act
of 1980, as amended ("CERCLA" or "Superfund"), for the cleanup of contamination
from hazardous substances at three Superfund sites (i.e. sites on the National
Priorities List ("NPL")) to which it has been alleged that TARC, or its
predecessors, sent hazardous substances in the past. CERCLA requires cleanup of
sites from which there has been a "release" or threatened release of "hazardous
substances" (as such terms are defined under CERCLA). CERCLA requires the EPA
to include sites needing long-term study and cleanup on the NPL based on their
potential effect on public health or the environment. CERCLA authorizes the EPA
to take any necessary response actions at NPL sites and, in certain
circumstances, to order PRPs liable for the release to take such actions. PRPs
are broadly defined under CERCLA to include past and present owners and
operators of a site, as well as generators and transporters of wastes to a site
from which hazardous substances are released.

         The EPA may seek reimbursement of expenditures of federal funds from
PRPs under Superfund. Courts have interpreted CERCLA to impose strict, joint
and several liability upon all persons liable for the entire amount of
necessary cleanup costs. As a practical matter, at sites where there are
multiple PRPs for a cleanup, the costs of cleanup typically are allocated
according to a volumetric or other standard among the parties. CERCLA also
provides that responsible parties generally may recover a portion of the costs
of cleaning up a site from other responsible parties.  Thus, if one party is
required to clean up an entire site, that party can seek contribution or
recovery of such costs from other responsible parties. A number of states have
laws similar to Superfund, pursuant to which cleanup obligations, or the costs
thereof, also may be imposed.

         At one Superfund site, TARC has submitted information to the EPA
indicating that it should have no liability for this matter, and negotiations
with the EPA in this regard are continuing. With respect to the remaining two
sites, TARC's liability for each such matter has not been determined, and TARC
anticipates that it may incur costs related to the cleanup (and possibly
including additional costs arising in connection with any recovery or other
actions brought pursuant or relating to such matters) at each such site. After
a review of the data available to TARC regarding the basis of TARC's alleged
liability at each site, and based on various factors, which depend on the
circumstances of the particular Superfund site (including, for example, the
relationship of TARC to each such site, the volume of wastes TARC is alleged to
have contributed to each such site in comparison to other PRPs without giving
effect to the ability of any other PRPs to contribute to or pay for any
liabilities incurred, and the range of likely cleanup costs at each such site)
TARC does not believe its ultimate environmental liabilities will be
significant; however, it is not possible to determine the ultimate
environmental liabilities, if any, that may arise from the matters discussed
above.

                               THE EXCHANGE OFFER

PURPOSE AND EFFECT OF THE EXCHANGE OFFER

         The Outstanding Notes were sold by the Company on June 13, 1997 to the
Initial Purchaser pursuant to the Purchase Agreement.  As a condition of the
purchase of the Outstanding Notes by the Initial Purchaser, the Company entered
into the Registration Rights Agreement with the Initial Purchaser, which
requires, among other things, that the Company file with the Commission a
registration statement under the Securities Act with respect to an offer by the
Company to the holders of the Outstanding Notes to issue and deliver to such
holders, in exchange for Outstanding Notes, a like principal amount of Exchange
Notes.  The Company is required to use its best efforts to cause the
Registration Statement relating to the Exchange Offer to be declared effective
by the Commission under the Securities Act and commence the Exchange Offer.
The Exchange Notes are to be issued without a restrictive legend and may be
reoffered and resold by the holder without restrictions or limitations under
the Securities Act (other than any such holder that is an "affiliate" of the
Company within the meaning of Rule 405 under the Securities Act).  A copy of
the Registration Rights Agreement has been filed as an exhibit to the
Registration Statement of which this Prospectus is a part.  The term "Holder"
with respect to the Exchange Offer means any person in whose name the
Outstanding Notes are registered on the books of the Company or any other
person who has obtained a properly completed bond power from the registered
holder.

TERMS OF THE EXCHANGE OFFER

         Upon the terms and subject to the conditions set forth in this
Prospectus and in the Letter of Transmittal, the Company will accept any and
all Outstanding Notes validly tendered and not withdrawn prior to 5:00 p.m.,
New York City time, on the Expiration Date.  On the Exchange Date, the Company
will issue $1,000 principal amount of Exchange Notes in exchange for $1,000
principal amount of Outstanding Notes accepted in the Exchange Offer.  Holders
may tender some or all of their Outstanding Notes pursuant to the Exchange
Offer.  However, Outstanding Notes may be tendered only in integral multiples
of $1,000.

         The forms and terms of the Exchange Notes are substantially the same
as the form and terms of the Outstanding Notes except that (i) the Exchange
Notes have been registered under the Securities Act and hence will not bear
legends restricting the transfer thereof and (ii) the holders of the Exchange
Notes will not be entitled to certain rights under the Registration Rights
Agreement.  The Exchange Notes will evidence the same debt as the Outstanding
Notes and will be entitled to the benefits of the Indenture.

         The Company has fixed the close of business on                 , 1997
as the record date for the Exchange Offer for purposes of determining the
persons to whom this Prospectus and the Letter of Transmittal will be mailed
initially.

         Holders of Outstanding Notes do not have any appraisal or dissenters'
rights under the General Corporation Law of Delaware or the Indenture in
connection with the Exchange Offer.  The Company intends to conduct the
Exchange Offer in accordance with the applicable requirements of the Exchange
Act and the rules and regulations of the Commission thereunder, including Rule
14e-1 thereunder.

         The Company shall be deemed to have accepted validly tendered
Outstanding Notes when, as and if the Company has given oral or written notice
thereof to the Exchange Agent.  The Exchange Agent will act as agent for the
tendering Holders for the purpose of receiving the Exchange Notes from the
Company.

         If any tendered Outstanding Notes are not accepted for exchange
because of an invalid tender, the occurrence of certain other events set forth
herein or otherwise, the certificates for any such unaccepted Outstanding Notes
will be returned, without expense, to the tendering Holder thereof as promptly
as practicable after the Expiration Date.





                                       30
<PAGE>   38
         Holders who tender outstanding Notes in the Exchange Offer will not be
required to pay brokerage commissions or fees or, subject to the instructions
in the Letter of Transmittal, transfer taxes with respect to the exchange of
Outstanding Notes pursuant to the Exchange Offer.  The Company will pay all
charges and expenses, other than transfer taxes in certain circumstances, in
connection with the Exchange Offer.  See "-- Fees and Expenses."

INTEREST ON THE EXCHANGE NOTES

         The Senior Secured Notes bear interest at a rate of  11 1/2% per
annum.  Interest on the Senior Secured Exchange Notes will accrue from the most
recent date on which interest has been paid or, if no interest has been paid,
from the issue date of the Outstanding Senior Secured Notes.  Interest on the
Senior Secured Notes will be payable semi- annually in cash in arrears on June
15 and December 15 of each year, commencing December 15, 1997.  The Senior
Secured Discount Notes will accrete at a rate of 13% per annum (compounded
semi-annually on June 15 and December 15 of each year) to 100% of the face
value thereof by June 15, 1999.  On their issue date the Senior Secured
Discount Notes will have the same Accreted Value as the Outstanding Senior
Secured Discount Notes on that date.  Cash interest on the Senior Secured
Discount Notes will be payable semi-annually in arrears on June 15 and December
15 of each year, commencing December 15, 1999, at a rate of 13% per annum.

PROCEDURES FOR TENDERING

         Only a Holder of Outstanding Notes may tender such Outstanding Notes
in the Exchange Offer.  To tender in the Exchange Offer, a Holder must
complete, sign and date the Letter of Transmittal, or a facsimile thereof, have
the signatures thereon guaranteed if required by the Letter of Transmittal and
mail or otherwise deliver such Letter of Transmittal or such facsimile,
together with the Outstanding Notes and any other required documents, to the
Exchange Agent prior to 5:00 p.m., New York City time, on the Expiration Date.
The Company is not asking any Holder for a proxy, and no Holder is requested to
send the Company a proxy.  To be tendered effectively, the Outstanding Notes,
Letter of Transmittal and other required documents must be received by the
Exchange Agent at the address set forth below under "Exchange Agent" prior to
5:00 p.m., New York City time, on the Expiration Date.  Delivery of the
Outstanding Notes may be made by book-entry transfer in accordance with the
procedures described below.  Confirmation of such book-entry transfer must be
received by the Exchange Agent prior to the Expiration Date.

         By executing the Letter of Transmittal, each Holder will make to the
Company the representations set forth below in the second paragraph under the
heading "-- Resale of Exchange Notes."

         The tender by a Holder and the acceptance thereof by the Company will
constitute an agreement between such Holder and the Company in accordance with
the terms and subject to the conditions set forth herein and in the Letter of
Transmittal.

         THE METHOD OF DELIVERY OF OUTSTANDING NOTES AND THE LETTER OF
TRANSMITTAL AND ALL OTHER REQUIRED DOCUMENTS TO THE EXCHANGE AGENT IS AT THE
ELECTION AND RISK OF THE HOLDER.  INSTEAD OF DELIVERY BY MAIL, IT IS
RECOMMENDED THAT HOLDERS USE AN OVERNIGHT OR HAND DELIVERY SERVICE.  IN ALL
CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE DELIVERY TO THE EXCHANGE
AGENT BEFORE THE EXPIRATION DATE.  NO LETTER OF TRANSMITTAL OR OUTSTANDING
NOTES SHOULD BE SENT TO THE COMPANY.  HOLDERS MAY REQUEST THEIR RESPECTIVE
BROKERS, DEALERS, COMMERCIAL BANKS, TRUST COMPANIES OR NOMINEES TO EFFECT THE
ABOVE TRANSACTIONS FOR SUCH HOLDERS.

         Any beneficial owner whose Outstanding Notes are registered in the
name of a broker, dealer, commercial bank, trust company or other nominee and
who wishes to tender should contact the registered holder promptly and instruct
such registered Holder to tender on such beneficial owner's behalf.





                                       31
<PAGE>   39
         Signatures on the Letter of Transmittal or a notice of withdrawal, as
the case may be, must be by an Eligible Institution (as defined below) unless
the Outstanding Notes tendered pursuant thereto are tendered (i) by a
registered Holder who has not completed the box entitled "Special Registration
Instructions" or "Special Delivery Instructions" on the Letter of Transmittal
or (ii) for the account of an Eligible Institution.  In the event that
signatures on a Letter of Transmittal or a notice of withdrawal, as the case
may be, are required to be guaranteed, such guarantee must be by a member firm
of a registered national securities exchange or of the National Association of
Securities Dealers, Inc., a commercial bank or trust company having an office
or correspondent in the United States or an "eligible guarantor institution"
within the meaning of Rule 17Ad-15 under the Exchange Act (an "Eligible
Institution").

         If the Letter of Transmittal is signed by a person other than the
registered Holder of any Outstanding Notes listed therein, such Outstanding
Notes must be endorsed or accompanied by a properly completed bond power,
signed by such registered Holder as such registered Holder's name appears on
such Outstanding Notes with the signature thereon guaranteed by an Eligible
Institution.

         If the Letter of Transmittal or any Outstanding Notes or bond powers
are signed by trustees, executors, administrators, guardians,
attorneys-in-fact, officers of corporations or others acting in a fiduciary or
representative capacity, such persons should so indicate when signing, and
unless waived by the Company, evidence satisfactory to the Company of their
authority to so act must be submitted with the Letter of Transmittal.

         The Company understands that the Exchange Agent will make a request
promptly after the date of this Prospectus to establish accounts with respect
to the Exchange Notes at the DTC (the "Book-Entry Transfer Facility") for the
purpose of facilitating the Exchange Offer, and subject to the establishment
thereof, any financial institution that is a participant in the Book-Entry
Transfer Facility's system may make book-entry delivery of the Outstanding
Notes by causing such Book-Entry Transfer Facility to transfer such Outstanding
Notes into the Exchange Agent's account with respect to the Outstanding Notes
in accordance with the Book-Entry Transfer Facility's procedures for such
transfer.  Although delivery of the Outstanding Notes may be effected through
book-entry transfer into the Exchange Agent's account at the Book-Entry
Transfer Facility, an appropriate Letter of Transmittal properly completed and
duly executed with any required signature guarantee and all other required
documents must in each case be transmitted to and received or confirmed by the
Exchange Agent at its address set forth below on or prior to the Expiration
Date, or, if the guaranteed delivery procedures described below are complied
with, within the time period provided under such procedures; provided, however,
that a participant in DTC's book-entry system may, in accordance with DTC's
Automated Tender Offer Program procedures and in lieu of physical delivery to
the Exchange Agent of a Letter of Transmittal, electronically acknowledge its
receipt of, and agreement to be bound by, the terms of the Letter of
Transmittal.  Delivery of documents to the Book-Entry Transfer Facility does
not constitute delivery to the Exchange Agent.

         All questions as to the validity, form, eligibility (including time of
receipt), acceptance and withdrawal of tendered Outstanding Notes will be
determined by the Company in its sole discretion, which determination will be
final and binding.  The Company reserves the absolute right to reject any and
all Outstanding Notes not properly tendered or any Outstanding Notes the
Company's acceptance of which would, in the opinion of counsel for the Company,
be unlawful.  The Company also reserves the right to waive any defects,
irregularities or conditions of tender as to particular Outstanding Notes.  The
Company's interpretation of the terms and conditions of the Exchange Offer
(including the instructions in the Letter of Transmittal) will be final and
binding on all parties.  Unless waived, any defects or irregularities in
connection with tenders of Outstanding Notes must be cured within such time as
the Company shall determine.  Although the Company intends to notify Holders of
defects or irregularities with respect to tenders of Outstanding Notes, neither
the Company, the Exchange Agent nor any other person shall incur any liability
for failure to give such notification.  Tenders of Outstanding Notes will not
be deemed to have been made until such defects or irregularities have been
cured or waived.  Any Outstanding Notes received by the Exchange Agent that are
not properly tendered and as to which the defects or irregularities have not
been cured or waived will be returned by the Exchange Agent to the tendering
Holders, unless otherwise provided in the Letter of Transmittal, as soon as
practicable following the Expiration Date.

GUARANTEED DELIVERY PROCEDURES

         Holders who wish to tender their Outstanding Notes and (i) whose
Outstanding Notes are not immediately available, (ii) who cannot deliver their
Outstanding Notes, the Letter of Transmittal or any other required documents to
the Exchange Agent or (iii) who cannot complete the procedures for book-entry
transfer,  prior to the Expiration Date, may effect a tender if:

         (a)   the tender is made through an Eligible Institution;

         (b)   prior to the Expiration Date, the Exchange Agent receives from
               the Eligible Institution a properly completed and duly executed
               Notice of Guaranteed Delivery (by facsimile transmission, mail
               or hand delivery) setting forth the name and address of the
               Holder, the certificate number(s) of such Outstanding Note(s)
               tendered, stating that the tender is being made thereby and
               guaranteeing that, within three New York Stock Exchange trading
               days after the Expiration Date, the Letter of Transmittal (or
               facsimile thereof), together with the certificate(s)
               representing the Outstanding Notes (or a confirmation of book-
               entry transfer of such Outstanding Notes into the Exchange
               Agent's account at the Book-Entry Transfer Facility) and any
               other documents required by the Letter of Transmittal, will be
               deposited by the Eligible Institution with the Exchange Agent;
               and

         (c)   such properly completed and executed Letter of Transmittal (or
               facsimile thereof), as well as  the certificate(s) representing
               all tendered Outstanding Notes in proper form for transfer and
               all other documents required by the Letter of Transmittal, are
               received by the Exchange Agent within three New York Stock
               Exchange trading days after the Expiration Date.

         Upon request to the Exchange Agent, a Notice of Guaranteed Delivery
will be sent to Holders who wish to tender their Outstanding Notes according to
the guaranteed delivery procedures set forth above.

WITHDRAWAL OF TENDERS

         Except as otherwise provided herein, tenders of Outstanding Notes may
be withdrawn at any time prior to 5:00 P.M., New York City time, on the
Expiration Date.

         To withdraw a tender of Outstanding Notes in the Exchange Offer, a
written or facsimile transmission notice of withdrawal must be received by the
Exchange Agent at its address set forth herein prior to 5:00 p.m., New York
City time, on the Expiration Date.  Any such notice of withdrawal must (i)
specify the name of the person having deposited the Outstanding Notes to be
withdrawn (the "Depositor"), (ii) identify the Outstanding Notes to be
withdrawn (including the certificate number(s) and principal amount of such
Outstanding Notes or, in the case of Outstanding Notes transferred by
book-entry transfer, the name and number of the account at the Book-Entry
Transfer Facility to be credited), (iii) be signed by the Holder in the same
manner as the original signature on the Letter of Transmittal by which such
Outstanding Notes were tendered (including any required signature guarantees)
or be accompanied by documents of transfer sufficient to have the Trustee with
respect to the Outstanding Notes register the transfer of such Outstanding
Notes into the name of the person withdrawing the tender,  (iv) specify the
name in which any such Outstanding Notes are to be registered, if different
from that of the Depositor, and (v) if applicable because the Outstanding Notes
have been tendered pursuant to book-entry procedures, specify the name and
number of the participant's account at DTC to be credited, if different from
that of the Depositor.  All questions as to the validity, form and eligibility
(including time of receipt) of such notices will be determined by the Company,
whose determination shall be final and binding on all parties.  Any Outstanding
Notes so withdrawn will be deemed not to have been validly tendered for
purposes of the Exchange Offer and no Exchange Notes will be issued with
respect thereto unless the Outstanding Notes so withdrawn are validly
retendered.  Any Outstanding Notes which have been tendered but which are not
accepted for exchange will be returned to the Holder thereof without cost to
such Holder as soon as practicable after withdrawal, rejection of tender or
termination of the Exchange Offer.  Properly withdrawn Outstanding Notes may be
retendered by following one of the procedures described above under "Procedures
for Tendering" at any time prior to the Expiration Date.

</TABLE>

FEES AND EXPENSES

         The expenses of soliciting tenders pursuant to the Exchange Offer will
be borne by the Company.  The principal solicitation is being made by mail;
however, additional solicitation may be made by telegraph, telephone, facsimile
or in person by officers and regular employees of the Company and its
affiliates.

         The Company has not retained any dealer-manager in connection with the
Exchange Offer and will not make any payments to brokers or others soliciting
acceptances of the Exchange Offer.  The Company, however, will pay the Exchange
Agent reasonable and customary fees for its services and registration expenses,
including fees and expenses of the Trustee, filing fees, blue sky fees and
printing and distribution expenses.

         The Company will pay all transfer taxes, if any, applicable to the
exchange of the Outstanding Notes pursuant to the Exchange Offer.  If, however,
certificates representing the Exchange Notes or the Outstanding Notes for the
principal amounts not tendered or accepted for exchange are to be delivered to,
or are to be issued in the name of, any person other than the person signing
the Letter of Transmittal, or if a transfer tax is imposed for any reason other
than the exchange of the Outstanding Notes pursuant to the Exchange Offer, then
the amount of any such transfer taxes (whether imposed on the registered Holder
or any other person) will be payable by the tendering Holder.

ACCOUNTING TREATMENT

         The Exchange Notes will be recorded at the same carrying value as the
Outstanding Notes as reflected in the Company's accounting records on the date
of exchange.  Accordingly, no gain or loss for accounting purposes will be
recognized.  The expenses of the Exchange Offer will be amortized over the term
of the Exchange Notes.

RESALE OF EXCHANGE NOTES

         Based on an interpretation by the staff of the Commission set forth in
no-action letters issued to third parties, the Company believes that Exchange
Notes issued pursuant to the Exchange Offer in exchange for Outstanding Notes
may be offered for resale, resold and otherwise transferred by any holder of
such Exchange Notes (other than any such holder which is an "affiliate" of the
Company within the meaning of Rule 405 under the Securities Act) without
compliance with the registration and prospectus delivery provisions of the
Securities Act, provided that such Exchange Notes are acquired in the ordinary
course of such holder's business and such holder does not intend to participate
and has no arrangement or understanding with any person to participate in the
distribution of such Exchange Notes.  Any holder who tenders in the Exchange
Offer with the intention to participate, or for the purpose of participating,
in a distribution of the Exchange Notes may not rely on the position of the
staff of the Commission enunciated in Exxon Capital Holdings Corporation
(available April 13, 1989) and Morgan Stanley & Co., Incorporated (June 5,
1991), or similar no-action letters, but rather must comply with the
registration and prospectus delivery requirements of the Securities Act in
connection with any resale transaction.  In addition, any such resale
transaction should be covered by





                                       34
<PAGE>   42
an effective registration statement containing the selling security holders
information required by Item 507 of Regulation S-K of the Securities Act.  Each
broker-dealer that receives Exchange Notes for its own account in exchange for
Outstanding Notes, where such Outstanding Notes were acquired by such
broker-dealer as a result of market-making activities or other trading
activities, must acknowledge that it will deliver a prospectus in connection
with any resale of such Exchange Notes.  See "Plan of Distribution."

         By tendering in the Exchange Offer, each Holder will represent to the
Company that, among other things, (i) the Exchange Notes acquired pursuant to
the Exchange Offer are being obtained in the ordinary course of business of the
person receiving such Exchange Notes, whether or not such person is a Holder,
(ii) neither the Holder nor any such other person has an arrangement or
understanding with any person to participate in the distribution of such
Exchange Notes and (iii) the Holder and such other person acknowledge that if
they participate in the distribution of the Exchange Notes (a) they must, in
the absence of an exemption therefrom, comply with the registration and
prospectus delivery requirements of the Securities Act in connection with any
resale of the Exchange Notes and cannot rely on the no-action letters
referenced above and (b) failure to comply with such requirements in such
instance could result in such Holder incurring liability under the Securities
Act for which such Holder is not indemnified by the Company.  Further, by
tendering in the Exchange Offer, each Holder that may be deemed an "affiliate"
(as defined under Rule 405 of the Securities Act) of the Company will represent
to the Company that such Holder understands and acknowledges that the Exchange
Notes may not be offered for resale, resold or otherwise transferred by that
Holder without registration under the Securities Act or an exemption therefrom.

         As set forth above, affiliates of the Company are not entitled to rely
on the foregoing interpretations of the staff of the Commission with respect to
resales of the Exchange Notes without compliance with the registration and
prospectus delivery requirements of the Securities Act.

PRIVATE EXCHANGE NOTES

         The Registration Rights Agreement provides that if, prior to
consummation of the Exchange Offer, the Initial Purchaser holds any Outstanding
Notes acquired by it and having, or which are reasonably likely to be
determined to have, the status of an unsold allotment in the initial
distribution, or any other holder of Outstanding Notes is not entitled to
participate in the Exchange Offer, the Company upon the request of such Initial
Purchaser or any such holder shall, simultaneously with the delivery of the
Exchange Notes in the Exchange Offer, issue and deliver to such Initial
Purchaser and any such holder, in exchange (the "Private Exchange") for such
Outstanding Notes held by such Initial Purchaser and any such holder, Private
Exchange Notes.  Any Private Exchange Notes will be issued pursuant to the same
Indenture as the Exchange Notes.  The Private Exchange Notes are not covered by
the registration statement of which this Prospectus is a part and are not being
offered hereby.  Any Private Exchange Notes will be entitled to all the rights
and subject to all the limitations applicable thereto under the Indenture, and
will be subject to the same restrictions on transfer applicable to untendered
Outstanding Notes.  However, pursuant to the Registration Rights Agreement,
holders of Private Exchange Notes have certain rights to require the Company to
file and maintain a shelf registration statement that would allow resales of
such Private Exchange Notes owned by such holders.  See "-- Shelf Registration
Statement."

SHELF REGISTRATION STATEMENT

         If (i) prior to the consummation of the Exchange Offer, either the
Company or the holders of a majority in aggregate principal amount of
Outstanding Notes determines in its or their reasonable judgment that (A) the
Exchange Notes would not, upon receipt, be tradeable by the holders thereof
without restriction under the Securities Act and the Exchange Act and without
material restrictions under applicable Blue Sky or state securities laws, or
(B) the interests of the holders under the Registration Rights Agreement, taken
as a whole, would be materially adversely affected by the consummation of the
Exchange Offer, (ii) applicable interpretations of the staff of the Commission
would not permit the consummation of the Exchange Offer prior to 90 days after
the effectiveness date of this Registration Statement, (iii) subsequent to the
consummation of a Private Exchange but within one year of the closing date of
the Original Notes Offering, the Initial Purchaser so requests, (iv) the
Exchange Offer is not consummated within 270 days of the Original





                                       35
<PAGE>   43
Notes Offering for any reason or (v) in the case of any holder not permitted to
participate in the Exchange Offer or of any holder participating in the
Exchange Offer that receives Exchange Notes that may not be sold without
material restriction under state and federal securities laws (other than due
solely to the status of such holder as an affiliate of the Company within the
meaning of the Securities Act) and, in either case contemplated by this clause
(v), such holder notifies the Company within six months of consummation of the
Exchange Offer, then the Company has agreed to file and maintain a registration
statement that would allow resales of transfer restricted Outstanding Notes,
Exchange Notes or Private Exchange Notes owned by such holders.

OTHER

         Participation in the Exchange Offer is voluntary and Holders should
carefully consider whether to accept.  Holders of the Outstanding Notes are
urged to consult their financial and tax advisors in making their own decision
on what action to take.

         The Company may in the future seek to acquire untendered Outstanding
Notes in open market or privately negotiated transactions through subsequent
exchange offers or otherwise.  The Company has no present plans to acquire any
Outstanding Notes that are not tendered in the Exchange Offer or to file a
registration statement to permit resales of any untendered Outstanding Notes.


                                USE OF PROCEEDS

         This Exchange Offer is intended to satisfy certain of the Company's
obligations under the Purchase Agreement and the Registration Rights Agreement.
The Company will not receive any cash proceeds from the issuance of the
Exchange Notes offered hereby.  In consideration for issuing the Exchange Notes

                                  THE COMPANY

GENERAL

         TransAmerican Energy Corporation is a holding company formed in 1994
that conducts operations through its subsidiaries, TransTexas and TARC, in two
segments of the energy industry: exploration and production of natural gas and
petroleum refining. The Company, TransTexas and TARC are all direct or indirect
subsidiaries of TransAmerican and its parent company, TNGC. In August 1993,
TransAmerican and its subsidiaries transferred their natural gas exploration,
production and transmission businesses to TransTexas. In October 1987,
TransAmerican transferred its refinery's net assets to TARC. The address of the
Company's principal executive offices is 1300 North Sam Houston Parkway East,
Suite 200, Houston, Texas 77032, and its telephone number at that address is
(281) 986-8822.

BACKGROUND

         Founded in 1958 by John R. Stanley with a single gas station,
TransAmerican grew rapidly and by the mid-1970s had developed a chain of over
200 independent gasoline stations in New England and New York. In the early
1970s, TransAmerican sought to vertically integrate its retail gasoline
operations by purchasing a refinery in Louisiana. In a further effort to
vertically integrate during this period, TransAmerican also entered the
exploration and production business by acquiring certain oil and gas properties
in South Texas and becoming one of the earliest significant developers of the
Lobo Trend. As a result of its successful gas drilling program in South Texas,
in 1974 TransAmerican began constructing pipeline systems for gathering and
transmission of its natural gas.

TRANSTEXAS

         TransTexas is engaged in the exploration for and development and
production of natural gas, primarily in South Texas. Since 1973, TransTexas has
drilled over 1,400 wells and discovered over 3.5 Tcfe of natural gas.
TransTexas' business strategy is to utilize its extensive experience gained
from over 20 years of drilling and operating wells in South Texas, to continue
to find, develop and produce reserves at a low cost. TransTexas has
traditionally performed most of its own well site preparation, drilling,
workover, completion, pipeline and production services.

         In 1994, as part of its strategy to expand its productive reserves
beyond the Lower Wilcox Lobo Trend (the "Lobo Trend") in Webb and Zapata
counties in South Texas, TransTexas began evaluating prospects that exhibited
the potential to add proved reserves of at least 50 Bcfe of natural gas per
development area. Since that time, TransTexas has evaluated over 300 potential
areas and its development of certain of these areas has resulted in substantial
additions to its reserves and production.

         In May 1997, TransTexas consummated the sale of TransTexas
Transmission Corporation ("TTC"), its subsidiary that owned substantially all
of TransTexas' Lobo Trend producing properties and related pipeline
transmission system, for a sales price of approximately $1.1 billion (the "Lobo
Sale").  As of February 1, 1997, the Lobo Trend producing properties divested
by the sale of the stock of TTC had proved reserves of approximately 550 Bcfe.
As of February 1, 1997, TransTexas' net proved reserves in the Continuing
Operations, as estimated by Netherland, Sewell & Associates, Inc., were 404
Bcfe.  As of July 31, 1997, after giving effect to the Lobo Sale, TransTexas
owned approximately 650,000 gross (475,000 net) acres of mineral interests.

         TransTexas' average net daily natural gas production for the year
ended January 31, 1997, was approximately 420 MMcfd, for a total net production
of 153.6 Bcf of natural gas.  After giving effect to the Lobo Sale, TransTexas'
average daily net production for the six months ended July 31, 1997 was
approximately 164 MMcfd of natural gas and 2,013 Bpd of crude oil and
condensate, for a total net production of 31.14 Bcfe.

         TransTexas' integrated drilling services division provides oil field
services including drilling, oil and natural gas well workover, stimulation and
completion, drilling fluids provision, pipeline construction and equipment
repair and maintenance to TransTexas. As of September 30, 1997, the assets of
this division included 25 land drilling rigs, nine workover rigs and two
fracture stimulation fleets. Complementary drilling, completion and workover
service equipment includes a ready-mix concrete plant, twin cementing trucks, a
coiled tubing unit, a snubbing unit, electric line and logging units, slickline
units, tag units and an extensive fleet of construction, inspection and other
rolling stock.

         TransTexas may contribute the assets of its drilling services division
to its wholly owned subsidiary, TransTexas Drilling Services, Inc. ("TTXD").
TransTexas is evaluating alternatives to maximize stockholder value with
respect to TTXD, including options such as a spin-off, a sale to a third party,
a merger or another business combination. In connection with the Lobo Sale,
TransTexas has entered into a long-term agreement, which can be transferred to
TTXD, pursuant to which it will provide drilling and certain other services to
the new operator of the Lobo Trend properties divested in the Lobo Sale.
TransTexas has also recently begun to provide drilling services to other third
parties.

TARC

         TARC owns a large petroleum refinery strategically located in the Gulf
Coast region along the Mississippi River, approximately 20 miles from New
Orleans, Louisiana. TARC's business strategy is to modify, expand and
reactivate its refinery and to maximize its gross refining margins by
converting low-cost, heavy, sour crude oils into high-value, light petroleum
products, including primarily gasoline and heating oil. In February 1995, TARC
began a construction and expansion program designed to reactivate the refinery
and increase its complexity. From February 1995 through April 1997, TARC spent
approximately $245 million on this program, procured a majority of the
essential equipment required and completed substantially all of the process
design engineering and a substantial portion of the remaining engineering
necessary to complete this project.

         The Transactions, when completed, will result in proceeds to TARC in
excess of the $427 million estimated budget for the Capital Improvement
Program, which is designed to reactivate the refinery and increase its
complexity.  Phase I of the Capital Improvement Program includes the completion
and start-up of several units, including the Delayed Coking Unit, one of the
refinery's major conversion units. TARC estimates that Phase I will be
completed at a cost of $223 million, will be tested and operational by
September 30, 1998, and will result in the refinery having the capacity to
process up to 200,000 Bpd of sour crude oil.  Phase II of the Capital
Improvement Program includes the completion and start-up of the Fluid Catalytic
Cracking Unit utilizing state-of-the-art milli-second catalytic cracking
("MSCC(SM)") technology and the installation of additional equipment expected
to further improve operating margins by allowing for a significant increase in
the refinery's capacity to produce gasoline. TARC estimates that Phase II will
be completed at a cost of $204 million and will be tested and operational by
July 31, 1999.  After completion of the Capital Improvement Program, TARC will
own and operate one of the largest independent refineries in the Gulf Coast
region, with a replacement cost estimated by management to be approximately
$1.4 billion.

                     SELECTED FINANCIAL AND OPERATING DATA

         On January 30, 1996, TEC changed its fiscal year end for financial
reporting purposes from July 31 to January 31. The following table sets forth
selected financial and operating data of TEC and its predecessor for and at the
end of each of the four years ended July 31, 1995, the six months ended January
31, 1995 and 1996, the years ended January 31, 1996 and 1997 and the six months
ended July 31, 1996 and 1997.  The financial data for the years ended July 31,
1992, 1993, 1994 and 1995, the six months ended January 31, 1996 and the year
ended January 31, 1997, are derived from the audited financial statements of
TEC. The financial data for the six months ended January 31, 1995, the year
ended January 31, 1996 and the six months ended July 31, 1996 and 1997 are
derived from the unaudited financial statements of TEC and contain all
adjustments (consisting only of normal recurring accruals) necessary, in the
opinion of management of TEC, for a fair presentation thereof.  The financial
data for fiscal years ended July 31, 1992 and 1993 represent the results of
operations and financial position of TEC's predecessor prior to the reactivation
of the refinery. During these periods, TARC had only maintenance expenses and
lease income for storage facilities. The data for the year ended July 31, 1994
reflects the limited operations of the refinery commenced in March 1994 and
expenses related to reactivation of portions of the refinery. Subsequent to
March 1994, TARC has operated the No. 2 Vacuum Unit intermittently. TARC does
not consider its historical results to be indicative of future results.

- ----------

(1)      Per share data for years prior to July 31, 1995 is omitted because
         TEC's predecessor was not a separate entity with its own capital
         structure.

(2)      Earnings were inadequate to cover fixed charges by $138.7 million,
         $26.9 million, $60.4 million, $172.5 million and $18.3 million for the
         year ended July 31, 1995, for the six months ended January 31, 1995
         and 1996 and the years ended January 31, 1996 and 1997, respectively.

(3)      Includes a 3.5 Bcf adjustment resulting from a favorable litigation
         settlement.

(4)      Sales volumes for the year ended January 31, 1997 and the six months
         ended July 31, 1997, include 32.0 Bcf and 7.3 Bcf, respectively,
         delivered pursuant to volumetric production payments

(5)      Average price calculations for the year ended January 31, 1997 and
         the six months ended July 31, 1997, include prices for amounts 
         delivered to third parties under volumetric production payments. The 
         average gas prices for TransTexas' undedicated production for these 
         periods were $2.39 per Mcf and $1.91 per Mcf, respectively. The gas 
         price does not include the effect of hedging.

(6)      These reserve data are estimates of TransTexas' proved reserves as of
         August 1, 1992, 1993, 1994 and 1995 and February 1, 1996 and 1997, as
         evaluated by Netherland Sewell & Associates, Inc.. No reserve 
         estimates were made for the six-month periods ended July 31, 1996 and 
         1997. See "Risk Factors-- General Risk Factors -- Risks Related to 
         Forward Looking Statements and Estimates."

(7)      As of February 1, 1997, the sales price used for purposes of
         estimating TransTexas' proved reserves and the future net cash flow
         from those reserves was $3.17 Mcf of natural gas and $23.99 per Bbl of
         condensate and oil.

(8)      For all periods prior to the Asset Transfer (as defined), data
         excludes all cash and accounts receivable because those assets were
         not transferred to TransTexas in the Asset Transfer. Working capital
         at July 31, 1995 and 1996, and January 31, 1996 and 1997, includes 
         $44.7 million, $46.0 million, $46.0 million and $46.0 million, 
         respectively, in a restricted interest reserve account pursuant 
         to the Indenture governing the TransTexas Senior Secured Notes.

(9)      Net income (loss) is prior to the preferred stock dividends of
         $19,000 for the year ended January 31, 1997 and the six months
         ended July 31, 1996 and 1997.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS

         Historically, TEC has conducted its operations through its operating
subsidiaries in three segments of the energy industry: exploration and
production of natural gas, natural gas transportation and petroleum refining.
After consummation of the Lobo Sale, TEC no longer conducts operations in the
natural gas transportation segment. TEC's only sources of liquidity and cash
flow will be payments on the Intercompany Loans and other loans to TEC's
subsidiaries, and dividends from and sales of stock of its subsidiaries.  Until
March 1994, the exploration, production and transportation operations of
TransTexas constituted substantially all of the operations of the Company. This
discussion should be read in conjunction with the consolidated financial
statements of TEC and its predecessor included in this Prospectus. The
financial data for the six months ended January 31, 1995, the year ended
January 31, 1996, and the six months ended July 31, 1996 and 1997 are derived
from the unaudited financial statements of TEC.  All of TEC's operations are
conducted through TransTexas and TARC.

         Business segment information for TEC and its predecessor for the years
ended July 31, 1994 and 1995, the six months ended January 31, 1995 and 1996,
the years ended January 31, 1996 and 1997 and the six months ended July 31,
1996 and 1997 is as follows:

TRANSTEXAS

     RESULTS OF OPERATIONS

         TransTexas' results of operations are dependent upon natural gas
production volumes and unit prices from sales of natural gas, condensate and
NGLs. The profitability of TransTexas also depends on the volume of natural gas
it gathers and transports, its ability to minimize finding and lifting costs
and maintaining its reserve base while maximizing production. On May 29, 1997,
TransTexas entered into and consummated a stock purchase agreement with an
unaffiliated buyer (the "Lobo Sale Agreement"), with an effective date of March
1, 1997, to effect the sale (the "Lobo Sale") of the stock of TransTexas
Transmission Corporation ("TTC"), its subsidiary that owned substantially all
of TransTexas' Lobo Trend producing properties and related pipeline
transmission system, for a sales price of approximately $1.1 billion, subject
to adjustments as provided for in the Lobo Sale Agreement. Accordingly, the
Company's reported results for the six months ended July 31, 1997 include the
effect of reduced volumes attributable to the producing properties divested as 
part of the Lobo Sale.

         TransTexas' operating data for the years ended July 31 1994 and 1995,
the six months ended January 31, 1995 and 1996, the years ended January 31,
1996 and 1997 and the six months ended July 31, 1996 and 1997, is as follows:

</TABLE>


      SIX MONTHS ENDED JULY 31, 1997, COMPARED WITH THE SIX MONTHS ENDED JULY
31, 1996

         Gas, condensate and NGL revenues for the six months ended July 31,
1997 decreased by $45.5 million from the comparable period of the prior year,
due primarily to decreases in gas, condensate and NGLs sales prices and gas
sales volumes, offset in part by increases in condensate sales volumes. The
average monthly prices received per Mcf of gas, excluding amounts dedicated to
volumetric production payments, ranged from $1.49 to $2.29 in the six months
ended July 31, 1997, compared to a range of $2.02 to $2.45 in the same period
of the prior year. The increase in condensate sales volumes is due primarily to
increased production from TransTexas' new development areas, offset in part by
the normal decline in natural gas production from the TransTexas Lobo Trend
wells and the disposition of such wells as a result of the Lobo Sale. NGLs
sales volumes decreased as a result of decreases in the volumes of natural gas
processed. Transportation revenues decreased by $4.8 million for the six months
ended July 31, 1997, due primarily to decreases in volumes transported and the
disposition of the pipeline system as a result of the Lobo Sale.





                                       45
<PAGE>   53
         Lease operating expenses in the six months ended July 31, 1997
decreased by $0.1 million from the prior year period due primarily to decreases
in the number of producing wells during the second quarter offset partially by
an increase in salt water disposal expense and the initiation of a program to
increase flow rates on certain of TransTexas' wells through increased workovers
and the installation of leased wellhead compressors. Pipeline operating
expenses decreased by $4.9 due primarily to the disposition of the pipeline
system as a result of the Lobo Sale. NGLs cost decreased by $8.7 million from
the comparable period in the prior year due to increases in the cost of natural
gas used in NGL processing, offset by a decrease in volumes of natural gas
processed. Depreciation, depletion and amortization expense for the six months
ended July 31, 1997 decreased by $7.9 million due to the decrease in
TransTexas' undedicated natural gas production partially offset by a $0.12
increase in the depletion rate. General and administrative expenses increased
by $4.7 million due primarily to increases in wages and benefits and litigation
expense. Taxes other than income taxes decreased by $4.6 million over the
comparable prior year period due primarily to a decrease in ad valorem and
excise taxes.

         Interest income for the six months ended July 31, 1997 increased by
approximately $5.4 million over the comparable period of the prior year due to
increased average cash balances. Interest expense decreased by $4.8 million
primarily as a result of the retirement of the TransTexas Senior Secured Notes
offset in part by the accretion on the TransTexas Subordinated Notes.

         Cash flow from operating activities for the six months ended July 31,
1997 decreased by approximately $154.2 million from the prior-year period due
primarily to lower net income from gas and oil production activities and
repayment of production payments in connection with the Lobo Sale.

         Cash used in investing activities increased by $602.7 million due to
proceeds from the sale of certain TransTexas producing properties offset in
part by the increase in cash restricted for share repurchases.

         Cash flow from financing activities decreased by approximately $464.3
million due primarily to the retirement of the TransTexas Senior Secured Notes
offset in part by the TransTexas Intercompany Loan of $450 million.

     YEAR ENDED JANUARY 31, 1997, COMPARED WITH THE YEAR ENDED JANUARY 31, 1996

         Gas, condensate and NGL revenues for the year ended January 31, 1997,
increased by $106.5 million from the year ended January 31, 1996, primarily due
to higher prices for and increased volumes of natural gas, condensate, oil and
NGLs, primarily in the fourth quarter. The average monthly prices received for
natural gas, excluding amounts delivered to third parties under volumetric
production payments, ranged from $1.71 to $3.74 per Mcf during the year ended
January 31, 1997, compared to prices ranging from $1.29 to $1.95 per Mcf in the
year ended January 31, 1996. The increase in natural gas sales volumes resulted
primarily from increased production from TransTexas' Bob West North development
area, offset in part by the normal decline in natural gas production from
TransTexas' Lobo Trend wells and the sale of approximately 207 Bcfe of
TransTexas' reserves in the Lobo Trend. NGLs sales volumes increased as a
result of increases in the volumes of natural gas processed. Transportation
revenues increased by $0.9 million for the year ended January 31, 1997,
primarily due to increased volumes of natural gas transported.

         Lease operating expenses for the year ended January 31, 1997 increased
by $8.8 million from the year ended January 31, 1996 primarily due to increases
in repairs and maintenance and workover expenses attributable to an increase in
the number of producing wells prior to the sale of certain of TransTexas' Lobo
Trend properties and the initiation in the first quarter of fiscal 1997 of a
program to increase flow rates on certain wells. This program included the
installation of leased wellhead compressors and additional workover projects.
Pipeline operating expenses increased by $12.8 million, primarily due to
increases in compressor fuel costs, compressor rentals, chemicals used in the
operation of TransTexas' amine plants and volumetric losses. NGLs cost
increased by $13.8 million from the year ended January 31, 1996 due to
increases in the cost of natural gas used in NGL processing. Depreciation,
depletion and amortization expense for the year ended January 31, 1997
increased by $11.9 million due to a $0.17 increase in the depletion rate,
offset in part by a decrease in TransTexas' undedicated natural gas production.
The depletion rate increased for the year ended January 31, 1997 primarily due
to higher costs associated with TransTexas' expanded





                                       46
<PAGE>   54
exploration activities. General and administrative expenses increased by $12.6
million in the year ended January 31, 1997, due primarily to increases in
litigation accruals and wages and benefits. Taxes other than income taxes
increased by $7.3 million over the year ended January 31, 1996 due primarily to
an increase in severance taxes, including an accrual of $2.7 million as a
result of a severance tax audit adjustment, offset in part by a reduction in ad
valorem taxes.

         Interest income for the year ended January 31, 1997, increased by
approximately $0.8 million from the year ended January 31, 1996 due to higher
average cash balances in fiscal 1997. Interest expense increased by $15.1
million primarily as a result of interest incurred on the TransTexas Senior
Secured Notes and the amortization of related debt issue costs, offset in part
by an increase of $7.6 million of interest capitalized in connection with the
acquisition of TransTexas' unevaluated gas and oil properties.

         Litigation settlements for the year ended January 31, 1997, increased
by $77.7 million as a result of the settlement with Tennessee Gas Pipeline
Company of which TransTexas' share of the proceeds was $96 million.

         Income tax expense for the year ended January 31, 1997, was $12.5
million compared to an income tax benefit of $4.2 million in the prior year.
Income tax expense for the year ended January 31, 1997 is net of a decrease in
a valuation allowance of $13.6 million relating to the utilization of net
operating loss carryforwards and tight sands credits of $7.4 million. Income
tax benefit for the year ended January 31, 1996 is net of a valuation allowance
of $13.6 million relating to net operating loss carryforwards and an adjustment
relating to tight sands credits of $7.8 million.

         Cash flow from operating activities for the year ended January 31,
1997, increased by approximately $148.9 million from the prior year primarily
due to increased net income, the settlement of take-or-pay litigation in the
second quarter of fiscal 1997 and proceeds from the sale of volumetric
production payments, partially offset by increases in working capital.

         Cash used in investing activities decreased by $67.9 million due to
the sale of approximately 207 Bcfe of TransTexas' reserves, offset in part by
advances to an affiliate and increased capital spending. Capital expenditures
for fiscal 1997 included $47.7 million for purchases of oil and gas properties
from TransAmerican.

         Cash flow from financing activities decreased by approximately $214.9
million from the year ended January 31, 1996 due primarily to the issuance of
the TransTexas Senior Secured Notes in June 1995, offset in part by the
issuance of the TransTexas Subordinated Notes in fiscal 1997.

     SIX MONTHS ENDED JANUARY 31, 1996, COMPARED WITH THE SIX MONTHS ENDED
JANUARY 31, 1995

         Gas, condensate and NGL revenues for the six months ended January 31,
1996, decreased by $18.6 million from the comparable period of the prior year,
due primarily to decreases in gas, condensate and NGL sales volumes, partly
offset by increases in gas, condensate and NGL prices. The decrease in gas
sales volumes reflects the normal decline in natural gas production from
TransTexas' Lobo Trend wells, offset in part by production from TransTexas' new
development areas. The average monthly prices received per Mcf of gas ranged
from $1.33 to $1.95 in the six months ended January 31, 1996, compared to a
range of $1.32 to $1.52 in the same period in the prior year. NGL sales volumes
decreased primarily due to the decrease in the volumes of natural gas
processed. Transportation revenues decreased by $3.3 million for the six months
ended January 31, 1996, due primarily to decreases in volumes transported.

         Lease operating expenses in the six months ended January 31, 1996,
decreased by $0.9 million from the prior year period as increases in repairs
and maintenance expenses attributable to the increase in the number of
producing wells were offset by a decrease in workover expense due to fewer
workovers performed. Pipeline operating expenses increased by $3.2 million due
primarily to increases in repairs and maintenance expenses, compressor fuel
costs and pipeline loss. Also contributing to the increase in pipeline
operating expenses were costs incurred by TransTexas to remove carbon dioxide
from natural gas produced from certain of TransTexas' new development areas.
NGL costs decreased by $8.9 million from the comparable period in the prior
year due to the decrease in volumes of natural gas processed. Depreciation,
depletion and amortization expense for the six months ended January 31, 1996,
decreased by





                                       47
<PAGE>   55
$9.4 million due to the decrease in natural gas production and a $0.02 decrease
in the depletion rate. General and administrative expenses increased by $1.1
million in the six months ended January 31, 1996, due primarily to costs
associated with the relocation of TransTexas' corporate offices, offset in part
by decreases in consulting and professional fees. The gain on litigation
settlement of $18.3 million represents the value of properties received in a
litigation settlement.

         Interest income for the six months ended January 31, 1996, increased
by approximately $2 million over the comparable period of the prior year due to
increased cash balances resulting from the issuance of the TransTexas Senior
Secured Notes. Interest expense increased by $13.4 million primarily as a
result of interest accrued on the TransTexas Senior Secured Notes and a
dollar-denominated production payment, offset in part by the capitalization of
approximately $7.4 million of interest in connection with the acquisition of
TransTexas' unevaluated gas and oil properties.

         Cash flow from operating activities for the six months ended January
31, 1996, decreased by approximately $21.2 million from the prior year period
primarily due to decreased production, offset in part by net proceeds of $32.9
million from the sale of a volumetric production payment.

         Cash used in investing activities increased by $31.4 million due to
increases in lease acquisitions and drilling activity, and the purchase and
installation of three amine plants to treat gas produced from certain of
TransTexas' new discovery areas. These increases were offset by cash proceeds
from the sale of a portion of TransTexas' Lodgepole properties and a
sale-leaseback of drilling equipment.

         Cash flow from financing activities decreased by approximately $5.2
million due primarily to repayments of TransTexas' dollar-denominated
production payment, offset in part by increases in long-term borrowings.

     YEAR ENDED JULY 31, 1995, COMPARED WITH THE YEAR ENDED JULY 31, 1994

         Gas, condensate and NGL revenues decreased by $26.9 million, due
primarily to the decline in prices for natural gas, offset in part by increases
in NGL and natural gas production. The average monthly prices received per Mcf
of gas ranged from a low of $1.29 to a high of $1.52 in the year ended July 31,
1995, compared to a low of $1.71 to a high of $2.21 in fiscal 1994. The
increase in gas sales volumes was due to a net increase in producing wells to
947 at July 31, 1995 from 865 at July 31, 1994. NGL production increased due to
increased volumes of TransTexas' natural gas processed at the Exxon King Ranch
Plant. Transportation revenues for the year ended July 31, 1995, increased by
$3.5 million compared to fiscal 1994 due primarily to increases in volumes
transported.

         Lease operating expenses decreased by $0.2 million, primarily as a
result of a decrease in operating materials and supplies expense. The decrease
in NGL cost of $0.4 million reflects the decrease in the cost of natural gas
used in NGL processing, offset in part by increased NGL production. Pipeline
operating expenses decreased by $4.3 million as increases in repair and
maintenance expenses associated with higher volumes transported were offset by
a decrease in compressor fuel costs. Depreciation, depletion and amortization
expenses increased by $16.1 million in the year ended July 31, 1995 over the
prior year due to the increase in natural gas production and a $0.01 increase
in the depletion rate. General and administrative expenses decreased by $8.4
million compared to the prior year due primarily to a $6.0 million decrease in
litigation accruals and a corresponding reduction in legal fees. Litigation
accruals totaled $7.0 million in the year ended July 31, 1995, compared to
$13.0 million in 1994.

         Interest expense for the year ended July 31, 1995, increased by $16.8
million over the prior year as a result of the increase in principal amount and
interest rate on the TransTexas Senior Secured Notes as compared to TransTexas'
previous indebtedness, along with interest accrued on TransTexas' production
payment, short-term borrowings and certain litigation settlements.





                                       48
<PAGE>   56
         Income tax benefit for the year ended July 31, 1995, is net of a
valuation allowance of $13.6 million relating to net operating loss
carryforwards and an adjustment relating to tight sands credits of $7.8
million. Income tax expense for the year ended July 31, 1994 includes $5.8
million of tax benefits that became available as a result of a change in tax
status of the TNGC Consolidated Group to an integrated oil company.

         TransTexas recorded an extraordinary loss of approximately $56.6
million, net of taxes, on the retirement of TransTexas' previous indebtedness.
This loss consists of $40.0 million in premium and consent fees paid to the
holders of TransTexas' previous indebtedness, $2.5 million in underwriting fees
and expenses and the recognition of approximately $15.6 million of unamortized
deferred financing costs, less a related income tax benefit of approximately
$1.5 million.

         Capital expenditures for the year ended July 31, 1995, increased by
$37.2 million to $278.5 million from $241.3 million for the prior year,
primarily due to an increase in lease acquisitions, offset in part by the
completion of a major pipeline expansion project in July 1994.

     INFLATION AND CHANGES IN PRICES

         TransTexas' results of operations and the value of its gas properties
are highly dependent upon the prices TransTexas receives for its natural gas.
Substantially all of TransTexas' sales of natural gas are made in the spot
market, or pursuant to contracts based on spot market prices, and not pursuant
to long-term, fixed-price contracts. Accordingly, the prices received by
TransTexas for its natural gas production are dependent upon numerous factors
beyond the control of TransTexas, including the level of consumer product
demand, the North American supply of natural gas, government regulations and
taxes, the price and availability of alternative fuels, the level of foreign
imports of oil and natural gas and the overall economic environment. Demand for
natural gas is seasonal, with demand typically higher during the summer and
winter, and lower during the spring and fall, with concomitant changes in
price. Although certain of TransTexas' costs and expenses are affected by the
level of inflation, inflation has not had a significant effect on TransTexas'
results of operations during the year ended January 31, 1997.

         Any significant decline in current prices for natural gas could have a
material adverse effect on TransTexas' financial condition, results of
operations and quantities of reserves recoverable on an economic basis. Based
on an assumed average net daily production level of 230 MMcfd (after giving
effect to the Lobo Sale), TransTexas estimates that a $0.10 per MMBtu change in
average gas prices received would change annual operating income by
approximately $6.4 million.

TARC

     RESULTS OF OPERATIONS

         TARC's refinery was inoperative from January 1983 through February
1994. During this period, TARC's revenues were derived primarily from tank
rentals and its expenses consisted of maintenance and repairs, tank rentals,
general and administrative expenses and property taxes. TARC commenced partial
operations at the refinery in March 1994 and has operated the No. 2 Vacuum Unit
intermittently since that time. TARC may operate the No. 2 Crude Unit and the
No. 2 Vacuum Unit if market conditions are favorable. TARC's decision to
commence or suspend operations is based on the availability of working capital,
current operating margins and the need to tie-in units as they are completed.
TARC does not consider its historical results to be indicative of future
results.

         TARC's results of operations are dependent on the operating status of
certain units within its refinery, which determines the types of feedstocks
processed and refined product yields. The results are also affected by the unit
costs of purchased feedstocks and the unit prices of refined products, which
can vary significantly. The Capital Improvement Program is designed to
significantly change TARC's throughput capacity, the feedstocks processed, and
refined product yields.





                                       49
<PAGE>   57
         TARC currently believes, based on estimates of refining margins and
current estimates for costs of the expansion and modification of the refinery,
that future undiscounted cash flows will be sufficient to recover the cost of
the refinery over its estimated useful life as well as the costs of related
identifiable intangible assets. Management believes there have been no events
or changes in circumstances that would require the recognition of an impairment
loss. However, due to the inherent uncertainties in estimating future refining
margins, and in constructing and operating a large scale refinery, there can be
no assurance that TARC will ultimately recover the cost of the refinery.
Management believes that the book value of the refinery is in excess of its
current estimated fair market value.

     SIX MONTHS ENDED JULY 31, 1997, COMPARED WITH THE SIX MONTHS ENDED JULY 31,
1996

         There were no revenues for the six months ended July 31, 1997 as
compared to $10.9 million for the same period in 1996, primarily as a result of
processing the majority of refinery throughput for the recent period under
processing agreements with third parties.

         There were no costs of products sold for the six months ended July 31,
1997 as compared to $12.4 million for the same period in 1996, due primarily to
TARC's use in 1997 of processing arrangements pursuant to which TARC
processed feedstock owned by third parties (as opposed to TARC's purchase of
feedstock and sale of product).

         Processing arrangements reflect income of $3.2 million and a loss of
$3.3 million for the six months ended July 31, 1997 and 1996, respectively.
Income and losses were primarily due to price management activities.

         Operations and maintenance expense for the six months ended July 31,
1997 increased $1.3 million to $7.9 million from $6.6 million for the same
period in 1996, primarily due to the increase of TARC's labor force in
connection with the Capital Improvement Program.

         Taxes other than income taxes for the six months ended July 31, 1997
decreased $1.1 million to $1.8 million from $2.9 million for the same period in
1996 primarily due to decreased property tax expense.

         Loss on purchase commitments for the six months ended July 31, 1997
consists of a $4.8 million loss related to a commitment to purchase 0.6 million
barrels of feedstock. These barrels have been sold to a third party and are now
subject to a processing agreement.

         Interest income for the six months ended July 31, 1997 increased $0.8
million as compared to the same period in 1996 primarily due to the investment
of proceeds from the TARC Intercompany Loan. Interest expense for the six
months ended July 31, 1997 increased $4.7 million, primarily due to interest on
promissory notes to TransAmerican and other long-term debt. During the six
months ended July 31, 1997, TARC capitalized approximately $41.6 million of
interest related to property and equipment additions at TARC's refinery
compared to $33.3 million for the six months ended July 31, 1996.

     Equity in income of TransTexas before extraordinary item for the six months
ended July 31, 1997 increased to $45.2 million as compared to $11.1 million for
the same period in 1996, due primarily to a $533 million gain on the sale by
TransTexas of a subsidiary. TARC recognized equity in an extraordinary item of
$(10.2) million for the six months ended July 31, 1997. The extraordinary loss
of TransTexas is attributable to a loss on the early extinguishment of debt as a
result of the repurchase by TransTexas of the TransTexas Senior Secured Notes
and the exchange of the TransTexas Subordinated Notes for the Old TransTexas
Subordinated Notes.

     YEAR ENDED JANUARY 31, 1997, COMPARED WITH THE YEAR ENDED JANUARY 31, 1996

         Total revenues for the year ended January 31, 1997, decreased to $10.9
million from $176.2 million for the same period in 1996, due primarily to a
significant drop in the processing of purchased feedstocks for sales to third
parties compared to the prior year.





                                       50
<PAGE>   58
         Cost of products sold for the year ended January 31, 1997, decreased
to $11.5 million from $185.3 million for the same period in 1996, due primarily
to a significant drop in the purchase of feedstocks for processing compared to
the prior year.

         Losses from processing arrangements of $7.1 million for the year ended
January 31, 1997, were primarily due to price management activities. See
"Business of TARC -- Financing Arrangements and Processing Agreements."

         Operations and maintenance expenses for the year ended January 31,
1997, increased to $23.9 million from $12.5 million for the same period in
1996, primarily due to a write-off of approximately $6.5 million for assets
included in construction work in process that will not be used in the overall
Capital Improvement Program, an increase in fuel costs during the first six
months of fiscal 1997, and higher contract labor costs.

         Depreciation and amortization expense for the year ended January 31,
1997, increased $0.9 million to $7.2 million from $6.3 million for the same
period in 1996, primarily due to the reclassification of construction work in
process to depreciable assets during 1997.

         Taxes other than income taxes for the year ended January 31, 1997,
increased to $4.2 million from $2.7 million for the same period in 1996,
primarily due to increased property tax expense.

         General and administrative expenses for the year ended January 31,
1997, decreased to $11.8 million from $12.6 million for the same period in
1996, primarily due to decreased litigation expense.

         Interest income for the year ended January 31, 1997, decreased by $6.1
million as compared to the same period in 1996, primarily due to interest
earned in 1996 on a higher balance held in the collateral account pursuant to
the TARC Notes Indenture. Interest expense, net, for the year ended January 31,
1997, decreased $13.8 million, primarily due to a larger portion of interest
being capitalized as well as a reduction of product financing costs in 1997
versus 1996 due to lower volumes of feedstock purchases. During the year ended
January 31, 1997, TARC capitalized approximately $68.8 million of interest
related to construction activities at TARC's refinery, compared to $41.5
million for the year ended January 31, 1996.

         The equity in income of TransTexas for the year ended January 31,
1997, of $12.3 million reflects TARC's 20.3% equity interest in TransTexas
until TARC's sale of 4.55 million shares of TransTexas common stock in March
1996 and its 14.1% interest thereafter. This compares to $2.6 million equity in
loss of TransTexas for the year ended January 31, 1996. The increase is a
result of higher gas prices and a favorable litigation settlement at
TransTexas.

         Other income for the year ended January 31, 1997, was $56.5 million,
which was primarily a result of the $56.2 million gain on the sale of 4.55
million shares of TransTexas common stock in March 1996. Other income for the
year ended January 31, 1996, was $2.1 million, primarily resulting from trading
gains on futures contracts.

     SIX MONTHS ENDED JANUARY 31, 1996, COMPARED WITH THE SIX MONTHS ENDED
JANUARY 31, 1995

         Total revenues for the six months ended January 31, 1996, increased
$35.6 million to $107.2 million from $71.6 million in the same period in 1995,
primarily due to an increase in the volume of products sold to 6.1 million
barrels in 1996 from 4.2 million barrels in 1995. In addition, $1.2 million of
the increase was due to an increase in the average product sales price of $0.19
per barrel in 1996 over 1995.

         Cost of products sold for the six months ended January 31, 1996,
increased $36.2 million to $110.1 million from $73.9 million for the same
period in 1995, primarily due to an increase in the volume of products sold,
partially offset by a decrease in the average price of feedstocks purchased.





                                       51
<PAGE>   59
         Operations and maintenance expenses for the six months ended January
31, 1996, increased $0.2 million to $7.9 million from $7.7 million for the same
period in 1995, primarily due to an increase in the number of days the No. 2
Vacuum Unit was operating.

         Depreciation and amortization expenses for the six months ended
January 31, 1996, increased $0.5 million to $3.2 million from $2.7 million for
the same period in 1995, primarily due to the transfer of certain terminal
facilities and tankage equipment from construction in progress to depreciable
assets during the 1996 period.

         General and administrative expenses for the six months ended January
31, 1996, decreased $1.0 million to $7.4 million from $8.4 million for the same
period in 1995, primarily as a result of a $2.5 million reduction in litigation
accruals, partially offset by an increase in payroll of $1.1 million arising
from operations support requirements.

         Taxes other than income taxes for the six months ended January 31,
1996, decreased $1.4 million to $0.7 million from $2.1 million for the same
period in 1995, primarily due to lower property tax expense for the six months
ended January 31, 1996.

         Interest income for the six-month period ended January 31, 1996,
increased $2.3 million compared to the same period in 1995 due primarily to
interest earned on long-term debt proceeds held in the collateral account under
the TARC Notes Indenture. Interest expense for the six-month period ended
January 31, 1996, increased $28.6 million due to interest accrued on long-term
debt issued in February 1995, amortization of debt issue costs and financing
costs associated with product purchases. During the six months ended January
31, 1996, TARC capitalized $26.2 million of interest related to property and
equipment associated with the construction and expansion program begun in 1995.

     YEAR ENDED JULY 31, 1995, COMPARED WITH THE YEAR ENDED JULY 31, 1994

         Total revenues for the year ended July 31, 1995, decreased $36.6
million to $140.6 million from $177.2 million in the same period in 1994,
primarily due to a decrease in the volume of products sold which was partially
offset by an increase in the average price of products sold.

         Cost of products sold for the year ended July 31, 1995, decreased
$19.8 million to $149.1 million from $168.9 million for the same period in
1994, primarily as a result of a decrease in volume of products sold, partially
offset by an increase in the average price of feedstocks purchased and a
contract cancellation loss of approximately $3.8 million.

         Operations and maintenance expenses for the year ended July 31, 1995,
increased $0.2 million to $12.3 million from $12.1 million for the same period
in 1994, primarily as a result of an increase in the number of days the No. 2
Vacuum Unit was operating.

         Depreciation and amortization expense for the year ended July 31,
1995, increased $3.3 million to $5.9 million from $2.6 million for the same
period in 1994, primarily as a result of increased depreciation expense being
recorded for refinery assets which were taken out of discontinued operations
during 1994.

         General and administrative expenses for the year ended July 31, 1995,
increased $9.1 million to $13.6 million from $4.5 million in the same period in
1994, primarily as a result of a litigation accrual of $4.5 million and
increases in legal and consulting fees and insurance costs as a result of
expanded refinery operations.

         Taxes other than income taxes for the year ended July 31, 1995,
increased $0.5 million to $4.2 million from $3.7 million for the same period in
1994, primarily as a result of an increase in property taxes assessed.

         Interest income for the year ended July 31, 1995, increased $4.1
million compared to the same period in 1994 due primarily to interest earned on
long-term debt proceeds held in the collateral account under the TARC Notes
Indenture. Interest expense for the year ended July 31, 1995, increased $31.3
million due to interest accrued on long- term debt issued during 1995,
amortization of debt issue costs and financing costs associated with product
purchases. During the year ended July 31, 1995, TARC capitalized $18.9 million
of interest related to construction activities associated with TARC's
construction and expansion program.





                                       52
<PAGE>   60
         Other income for the year ended July 31, 1995, was $2.5 million
compared to other expense of $2.9 million for the same period in 1994 primarily
as a result of trading gains on futures contracts in 1995.

         For the year ended July 31, 1995, the loss before an extraordinary
item increased $35.5 million over the same period in 1994, primarily due to
interest associated with TARC's long-term debt and amortization of debt issue
costs.

         In February 1995, TransAmerican contributed 55 million shares of
TransTexas common stock to TEC. TEC then contributed 15 million of these shares
of TransTexas common stock to TARC. The equity in the loss of TransTexas for
the year ended July 31, 1995, reflects TARC's 20.3% equity interest in
TransTexas' loss before an extraordinary item from the date of acquisition. The
equity in extraordinary loss of TransTexas represents TARC's equity in a charge
recorded by TransTexas in the fourth quarter for the early retirement of $500
million of its 10 1/2% Senior Secured Notes due 2000 from the proceeds of the
issuance by TransTexas in June 1995 of the TransTexas Senior Secured Notes.

     INFLATION AND CHANGES IN PRICES

         TARC's revenues and feedstock costs have been and will continue to be
affected by changes in the prices of petroleum and petroleum products. TARC's
ability to obtain additional capital is also substantially dependent on
refining margins, which are subject to significant seasonal, cyclical and other
fluctuations that are beyond TARC's control.

         From time to time, TARC enters into futures contracts, options on
futures, swap agreements and forward sale agreements for crude and refined
products intended to protect against a portion of the price risk associated
with price declines from holding inventory of feedstocks and refined products,
or for fixed price purchase commitments. TARC's policy is not to enter into
fixed price or other purchase commitments in excess of anticipated processing
requirements. TARC believes that these current and anticipated futures
transactions do not and will not constitute speculative trading as specified
under and prohibited by the Indenture.

RECENTLY ISSUED PRONOUNCEMENTS

         In June 1997, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards No. 131, "Disclosures about
Segments of an Enterprise and Related Information" ("SFAS 131"), which
establishes standards for reporting information about operating segments.  It
also establishes standards for related disclosures about products and services,
geographic areas and major customers.  This statement will be adopted by the
Company effective February 1, 1998.  The Company does not believe the effect of
adoption of this statement will have a material effect on its financial
position.

         In June 1997, the Financial Accounting Standards Board issued
Statement of Financial Accounting Standards No. 130, Reporting Comprehensive
Income, ("SFAS 130") which establishes standards for reporting and display of
comprehensive income and its components in financial statements. This statement
will be adopted by the Company effective February 1, 1998. The Company does not
believe the effect of adoption of this statement will have a material effect on
its financial statements.

         In February 1997, the Financial Accounting Standards Board issued
Statement of Financial Accounting Standards No. 128, Earnings per Share ("SFAS
128") and Statement of Financial Accounting Standards No. 129, Disclosure of
Information about Capital Structure ("SFAS 129"). These statements will be
adopted by TARC effective January 31, 1998. SFAS 128 simplifies the computation
of earnings per share by replacing primary and fully diluted presentations with
the new basic and diluted disclosures. SFAS 129 establishes standards for
disclosing information about an entity's capital structure. TARC has not
determined the impact of these pronouncements on its financial statements.

         In October 1996, the American Institute of Certified Public
Accountants issued Statement of Position 96-1, Environmental Remediation
Liabilities ("SOP 96-1"), which establishes new accounting and reporting
standards for the recognition and disclosure of environmental remediation
liabilities. TARC does not believe the effect of adoption of SOP 96-1 in 1998
will have a material impact on TARC's financial position, results of operations
or cash flows.

LIQUIDITY AND CAPITAL RESOURCES

         TEC completed the Original Notes Offering on June 13, 1997 of $475
million aggregate principal amount of Outstanding Senior Secured Notes and
$1.13 billion aggregate principal amount of Outstanding Senior Secured Discount
Notes for net proceeds of approximately $1.3 billion.





                                       53

         With the proceeds of the Original Notes Offering, TEC made the
TransTexas Intercompany Loan in the principal amount of $450 million and the
TARC Intercompany Loan in the original amount of $676 million. The promissory
note evidencing the TransTexas Intercompany Loan (i) bears interest at a rate
of 10 7/8% per annum, payable semi-annually in cash in arrears and (ii) is
currently secured by a security interest in substantially all of the assets of
TransTexas other than Inventory, Receivables and Equipment. The promissory note
evidencing the TARC Intercompany Loan (i) accretes principal at the rate of 16%
per annum, compounded semi-annually, until June 15, 1999 to a final accreted
value of $920 million, and thereafter pays interest semi-annually in cash in
arrears on the accreted value thereof, at a rate of 16% per annum and (ii) is
currently secured by a security interest in substantially all of TARC's assets,
including the shares of TransTexas stock owned by TARC, but excluding
Inventory, Receivables and Equipment. The Intercompany Loans will mature on
June 1, 2002. The Intercompany Loan Agreements contain certain restrictive
covenants including, among others, limitations on incurring additional debt,
asset sales, dividends and transactions with affiliates. Upon the occurrence of
a Change of Control (as defined), TEC will be required to make an offer to
purchase all of the outstanding Notes at a price equal to 101% of the principal
amount thereof, together with accrued and unpaid interest, if any, or, in the
case of any such offer to purchase the Senior Secured Discount Notes prior to
June 15, 1999, at a price equal to 101% of the accreted value thereof, in each
case, to and including the date of purchase. Pursuant to the terms of the
Intercompany Loans, TEC may require TransTexas and TARC to pay a pro rata share
of the purchase price paid by TEC. See "-- Potential Effects of a Change of
Control."

         On June 13, 1997, TEC completed a tender offer for all of the
outstanding common stock purchase warrants of TARC ("TARC Warrants") at a price
of $4.50 per warrant. Pursuant to the tender offer, TEC purchased 7,335,452
TARC Warrants for an aggregate purchase price of approximately $33 million. TEC
or TARC may repurchase additional TARC Warrants, and TARC intends to enter into
a merger with one of its affiliates pursuant to which each remaining TARC
Warrant would become exercisable (at an exercise price of $.01) to receive
$4.51 of cash instead of one share of common stock of TARC.

         TEC paid a dividend to TransAmerican in the amount of $23 million on
June 13, 1997. A portion of the dividend was used to repay the debt of an
affiliate, which had been secured by a pledge of 3.7 million shares of
TransTexas common stock. In connection with the Original Notes Offering,
TransAmerican contributed the 3.7 million shares of TransTexas common stock to
TEC.

         TEC's only source of funds for its holding company operations and debt
service will be payments on the Intercompany Loans and other loans to
subsidiaries, dividends from its subsidiaries, interest on funds in the TARC
Disbursement Account, payments made by TARC on behalf of TEC and, in limited
circumstances as permitted by the Indenture, sales of stock TEC holds in its
subsidiaries.

         During the two years following the Original Notes Offering, TEC
anticipates that its annual cash needs for holding company operations will be
approximately $2.0 million, which TEC expects to be paid on its behalf by TARC
pursuant to the Services Agreement, and TEC's annual cash interest expense will
be approximately $54.6 million. In addition, TEC and its subsidiaries will pay
$2.5 million in the aggregate per year to TransAmerican for advisory services
and other benefits provided by TransAmerican. TransTexas will be required to
pay TEC approximately $48.9 million in interest annually on the TransTexas
Intercompany Loan. TEC expects to use this interest income together with
working capital and interest income from other intercompany advances to satisfy
its cash needs, including its cash interest payments. If TEC incurs unforeseen
expenses, there is no assurance that its capital resources will be sufficient
to fund those expenses in addition to anticipated holding company expenses and
debt service.

         The Indenture prohibits TEC from selling stock of TransTexas and TARC
during the two years following consummation of the Original Notes Offering
unless the proceeds from such sales would be used to make an offer to purchase
the Notes. Consequently, during the two years following the consummation of the
Original Notes Offering, unless holders of the Notes rejected all or a portion
of any such offer to purchase, sales of such stock would not be a source of
funds to supplement TEC's other resources in order to pay unforeseen expenses.





                                       54

         On May 29, 1997, TransTexas consummated the Lobo Sale Agreement, with
an effective date of March 1, 1997, to effect the Lobo Sale, for a sales price
of approximately $1.1 billion, subject to adjustments as provided for in the
Lobo Sale Agreement. Purchase price adjustments were made for, among other
things: the value of certain NGLs and stored hydrocarbons; the value of gas in
TTC's pipeline; prepaid expenses relating to post-effective date operations;
post-closing expenses related to pre-closing operations; the value of oil and
gas produced and sold between the effective date of the Lobo Sale Agreement and
closing (approximately $44 million); property defects; and estimated costs
associated with liabilities discovered before closing. Purchase price
adjustments made at the closing of the Lobo Sale are subject to a review,
reconciliation and resolution process. With proceeds from the Lobo Sale,
TransTexas repaid certain indebtedness and other obligations, including
production payments, in an aggregate amount of approximately $84 million. The
remaining net proceeds have been or will be used for the redemption or
repurchase of the TransTexas Senior Secured Notes and for general corporate
purposes.

         On June 13, 1997, TransTexas completed a tender offer for the
TransTexas Senior Secured Notes for 111 1/2% of their principal amount (plus
accrued and unpaid interest). Approximately $785.4 million principal amount of
TransTexas Senior Secured Notes were tendered and accepted by TransTexas. The
TransTexas Senior Secured Notes remaining outstanding were called for
redemption on June 30, 1997 pursuant to the terms of the indenture governing
such notes.

         On June 19, 1997, TransTexas completed an exchange offer, pursuant to
which it exchanged approximately $115.8 million aggregate principal amount of
its 13 3/4% Senior Subordinated Notes due 2001 (the "TransTexas Subordinated
Notes") for all of the Old TransTexas Subordinated Notes. The TransTexas
Subordinated Notes pay interest in cash semi- annually in arrears on each June
30 and December 31 commencing December 31, 1997. The indenture governing the
TransTexas Subordinated Notes (the "TransTexas Subordinated Notes Indenture")
includes certain restrictive covenants, including, among others, limitations on
incurring additional debt, asset sales, dividends and transactions with
affiliates.

         TransTexas has implemented the Stock Repurchase Program pursuant to
which it plans to repurchase common stock from its public stockholders and from
its affiliates, including TEC and TARC, in an aggregate amount of approximately
$399 million in value of stock purchased. It is anticipated that TransTexas
will acquire four times the number of shares from its affiliated stockholders
that it acquires from its public stockholders. Shares may be purchased through
open market purchases, negotiated transactions or tender offers, or a
combination of the above. It is anticipated that the price paid to affiliated
stockholders will equal the weighted average price paid to purchase shares from
the public stockholders. As of September 30, 1997, approximately 3.9 million
shares had been repurchased from public stockholders for an aggregate purchase
price of approximately $61.4 million, and approximately 12.6 million shares had
been repurchased from TARC and TEC for an aggregate purchase price of
approximately $201 million.

         TransTexas and BNY Financial Corporation are parties to an Amended and
Restated Accounts Receivable Management and Security Agreement (the "BNY
Facility"), dated as of October 31, 1995 and amended in December 1996. In
connection with the Lobo Sale, the TEC Notes Offering and the Transactions
described in Note 2 of Notes to Condensed Consolidated Financial Statements,
TransTexas and BNY entered into a waiver of the BNY Facility, pursuant to which
advances under the BNY Facility are made at the sole discretion of the lender
and the lender may require repayment of principal and interest at any time. As
of July 31, 1997, outstanding advances under the BNY Facility totaled
approximately $6.2 million. Interest accrues on advances at the rate of (i) the
higher of (a) the prime rate of The Bank of New York or (b) the Federal Funds
Rate plus 1/2 of 1% plus (ii) 1/2 of 1%. Obligations under the BNY Facility are
secured by liens on TransTexas' receivables and inventory. TransTexas is
currently negotiating an amendment and restatement of the BNY Facility.

         During the months of April and May 1997, TransTexas obtained
additional financing in the aggregate amount of approximately $45.8 million, of
which approximately $21.0 million remains outstanding. Proceeds from these
transactions, net of current maturities, were used to pay certain short-term
obligations outstanding at January 31, 1997.





                                       55
<PAGE>   63
         TransTexas makes substantial capital expenditures for the exploration
for and development and production of natural gas. TransTexas historically has
financed its capital expenditures, debt service and working capital
requirements with cash from operations, public and private offerings of debt
and equity securities, the sale of production payments, asset sales, its
accounts receivable revolving credit facility and other financings. Cash flow
from operations is sensitive to the prices TransTexas receives for its natural
gas. TransTexas from time to time enters into commodity price swap agreements
to reduce its exposure to price risk in the spot market for natural gas. All of
its current production, however, remains subject to price risk. Proceeds from
natural gas sales are received at approximately the same time that
production-related burdens, such as royalties, production taxes and drilling
program obligations are payable. TransTexas' leverage and debt covenants may
limit its ability to obtain additional financings.

         For the six months ended July 31, 1997, total capital expenditures for
TransTexas were $206 million, including $41 million for lease acquisitions,
$129 million for drilling and development and $36 million for TransTexas' gas
gathering and pipeline system and other equipment and seismic acquisitions.
During this period, TransTexas accelerated its exploration and development
drilling program which included the successful exploration efforts in Galveston
Bay, Goliad County and Brazoria County and, as a result, its capital
expenditures for fiscal 1998 will significantly exceed its original anticipated
amount of $220 million. Anticipated capital expenditures in fiscal 1998,
including the development of the successful exploration areas will require
supplementing cash flow from operations with asset sales or financings.

         On June 13, 1997, TARC completed a tender offer (the "TARC Notes
Tender Offer") for the (i) TARC Mortgage Notes for 112% of their principal
amount (plus accrued and unpaid interest) and (ii) TARC Discount Notes for 112%
of their accreted value. TARC Mortgage Notes and TARC Discount Notes with an
aggregate carrying value of $423 million were tendered and accepted by TARC at
a cost to TARC of approximately $437 million (including accrued interest,
premiums and other costs). As a result of the TARC Notes Tender Offer, $17.2
million in debt issuance costs were written off and TARC recorded a total
extraordinary charge of approximately $84 million during the quarter ended July
31, 1997. As of July 31, 1997, TARC Mortgage Notes and TARC Discount Notes with
a carrying value of $15.7 million remained outstanding.

         The Indenture permits TARC to obtain a revolving credit facility but
places certain limitations on TARC's ability to incur other indebtedness. In
order to operate the refinery at expected levels after the completion of Phase
I of the Capital Improvement Program, TARC will require additional working
capital. Although TARC and a lender have engaged in discussions concerning the
terms of a revolving credit facility, there can be no assurance TARC will be
able to obtain such a facility.

         TARC intermittently operates certain completed units of the refinery
pursuant to certain processing agreements. TARC anticipates that, until
completion of the Delayed Coking Unit, its capital needs will be limited to
expenditures for the Capital Improvement Program, general and administrative
expenses and refinery maintenance costs.

         Following completion of the Transactions, TARC and TEC will have
deposited approximately $529 million into the TARC Disbursement Account from
which disbursements will be made pursuant to the TARC Disbursement Agreement.
See Note 4 to Notes to Condensed Financial Statements. Of these funds, $427
million will be available only for the Capital Improvement Program,
approximately $25.5 million will be available for general and administrative
expenses, $7 million will be available for outstanding accounts payable, $50
million will be available for working capital upon completion of the Delayed
Coking Unit and certain supporting units and $19 million will be available for
the payment of interest on, or the redemption, purchase, defeasance or other
retirement of, the outstanding TARC Notes. TARC's estimated capital
expenditures for the Capital Improvement Program are $201 million, $210
million, and $16 million, respectively, during the remainder of fiscal 1998,
and the fiscal years ending January 31, 1999 and 2000. If engineering problems,
cost overruns or delays occur and other financing sources are not available,
TARC may not be able to complete both phases of the Capital Improvement
Program. As of July 31, 1997, $24.9 million had been disbursed to TARC out of
the TARC Disbursement Account for use in the Capital Improvement Program and 
$7.0 million for general corporate purposes.





                                       56
<PAGE>   64
         In April 1996, TARC entered into a processing agreement with a third
party to process feedstocks. Under the terms of the agreement, the processing
fee earned by the third party is based on the margin earned by the third party,
if any, after deducting all of its related costs such as feedstock acquisition,
hedging, transportation, processing and inspections plus a commission for each
barrel processed. As of July 31, 1997, TARC has processed 6.4 million barrels
of feedstocks under this agreement. As of July 31, 1997 and January 31, 1997,
TARC was storing approximately 0.8 million and 1.0 million barrels,
respectively, of feedstock and intermediate or refined products. For the six
months ended July 31, 1997 and 1996, TARC recorded income (loss) from
processing agreements of $3.2 million and $(3.3) million, respectively.
Included in the 0.8 million barrels of product stored at the refinery as of
July 31, 1997, is approximately 0.6 million barrels of feedstock related to a
purchase commitment entered into in April 1997. The 0.6 million barrels have
been sold to the third party involved in the processing arrangement. For the
six months ended July 31, 1997, TARC incurred a loss of approximately $4.8
million related to this purchase commitment.

         TARC also entered into processing agreements with this third party to
process approximately 1.1 million barrels of the third party's feedstocks for a
fixed price per barrel. As of July 31, 1997, TARC recorded a net margin of
approximately $0.2 million related to these processing arrangements, primarily
as a result of income on the fixed fee processing agreement.

         In September 1997, TARC purchased a tank storage facility adjacent to
the refinery for a purchase price of $40 million.

         Environmental compliance and permitting issues are an integral part of
the capital expenditures anticipated in connection with the expansion and
modification of the refinery. TARC does not expect to incur any additional
significant expenses for environmental compliance during fiscal 1998 or fiscal
1999 other than those budgeted for the Capital Improvement Program. There is no
assurance, however, that costs incurred to comply with environmental laws will
not have a material adverse effect on TARC's future results of operations, cash
flows or financial condition. TARC also has contingent liabilities with respect
to litigation matters as more fully described in the Condensed Consolidated
Financial Statements included elsewhere in this Prospectus.

     CONTINGENT LIABILITIES

         TransTexas has significant contingent liabilities, including
liabilities with respect to litigation matters as described above. These
matters, individually and in the aggregate, amount to significant potential
liability which, if adjudicated in a manner adverse to TransTexas in one
reporting period, could have a material adverse effect on TransTexas' cash flow
or operations for that period. Although the outcome of these contingencies or
the probability of the occurrence of these contingencies cannot be predicted
with certainty, TransTexas does not expect these matters to have a material
adverse effect on its financial position. TransTexas has caused delivery of a
letter of credit to secure potential liabilities totaling approximately $20
million in connection with certain litigation described above.

         In January 1996, TransTexas entered into a reimbursement agreement
with an unaffiliated third party pursuant to which the third party caused a $20
million letter of credit to be issued to collateralize a supersedeas bond on
behalf of TransTexas. If there is a draw under the letter of credit, TransTexas
is required to reimburse the third party within 60 days. TransTexas has agreed
to issue up to 8.6 million shares of common stock of TransTexas to the third
party if this contingent obligation to such third party becomes fixed and
remains unpaid for 60 days. TransTexas does not believe that this contingency
will occur. If the obligation becomes fixed, and alternative sources of capital
are not available, TransTexas could elect to sell shares of TransTexas' common
stock prior to the maturity of the obligation and use the proceeds of such sale
to repay the third party. Based on TransTexas' current capitalization, the
issuance of shares of TransTexas' common stock to satisfy this obligation would
result in deconsolidation of TransTexas for federal income tax purposes.





                                       57
<PAGE>   65
         Pursuant to the Lobo Sale Agreement, TransTexas is required to
indemnify the buyer for certain liabilities related to the assets owned by TTC.
Although TransTexas does not anticipate that it will incur any material
indemnity liability, no assurance can be given that TransTexas will have
sufficient funds to satisfy any such indemnity obligation or that any payment
thereof will not have a material adverse effect on its ability to fund its debt
service, capital expenditure and working capital requirements.

     POTENTIAL TAX LIABILITY

         Part of the refinancing of TransAmerican's debt in 1993 involved the
cancellation of approximately $65.9 million of accrued interest and of a
contingent liability for interest of $102 million owed by TransAmerican.
TransAmerican has taken the federal tax position that the entire amount of this
debt cancellation is excluded from its income under the cancellation of
indebtedness provisions (the "COD Exclusion") of the Internal Revenue Code of
1986, as amended, and has reduced its tax attributes (including its net
operating loss and credit carryforwards) as a consequence of the COD Exclusion.
No federal tax opinion was rendered with respect to this transaction, however,
and TransAmerican has not obtained a ruling from the Internal Revenue Service
(the "IRS") regarding this transaction. TransTexas believes that there is
substantial legal authority to support the position that the COD Exclusion
applies to the cancellation of TransAmerican's indebtedness. However, due to
factual and legal uncertainties, there can be no assurance that the IRS will
not challenge this position, or that such challenge would not be upheld. Under
an agreement between TransTexas, TransAmerican and certain of TransAmerican's
subsidiaries (the "Tax Allocation Agreement"), TransTexas has agreed to pay an
amount equal to any federal tax liability (which would be approximately $25.4
million) attributable to the inapplicability of the COD Exclusion. Any such tax
would be offset in future years by alternative minimum tax credits and retained
loss and credit carryforwards to the extent recoverable from TransAmerican. As
a member of the TNGC Consolidated Group (defined below), each of TransTexas,
TEC and TARC will be severally liable for any tax liability resulting from the
above-described transactions. The IRS has commenced an audit of the
consolidated federal income tax returns of the TNGC Consolidated Group for its
taxable years ended July 31, 1994 and 1995. Because the audit is in its initial
stages, it is not possible to predict the scope of the IRS' review or whether
any tax deficiencies will be proposed by the IRS as a result of its review.

         Based upon independent legal advice, TransTexas has determined that it
will not report any significant federal income tax liability as a result of the
Lobo Sale. There are, however, significant uncertainties regarding TransTexas'
tax position and no assurance can be given that TransTexas' position will be
sustained if challenged by the IRS. TransTexas is part of an affiliated group
for tax purposes (the "TNGC Consolidated Group"), which includes TNGC Holdings
Corporation, the sole stockholder of TransAmerican. No letter ruling has been
or will be obtained from the IRS regarding the Lobo Sale by any member of the
TNGC Consolidated Group. If the IRS were to successfully challenge TransTexas'
position, each member of the TNGC Consolidated Group would be severally liable
under the consolidated tax return regulations for the resulting taxes, in the
estimated amount of up to $250 million (assuming the use of existing tax
attributes of the TNGC Consolidated Group), possible penalties equal to 20% of
the amount of the tax, and interest at the statutory rate (currently 9%) on the
tax and penalties (if any). The Tax Allocation Agreement has been amended so
that TransAmerican will become obligated to fund the entire tax deficiency (if
any) resulting from the Lobo Sale. There can be no assurance that TransAmerican
would be able to fund any such payment at the time due and the other members of
the TNGC Consolidated Group, thus, may be required to pay the tax. TransTexas
has reserved approximately $75 million with respect to the potential tax
liability for financial reporting purposes to reflect a portion of the federal
tax liability that TransAmerican might not be able to pay. If TransTexas were
required to pay this tax deficiency, it is likely that it would be required to
sell significant assets or raise additional debt or equity capital to fund the
payment.

         Under certain circumstances, TransAmerican or TEC may sell or
otherwise dispose of shares of common stock of the Company. If, as a result of
any sale or other disposition of the Company's common stock, the aggregate
ownership of TransTexas by members of the TNGC Consolidated Group (excluding
TransTexas) is less than 80% (measured by voting power and value), TransTexas
will no longer be a member of the TNGC Consolidated Group for federal tax
purposes ("Deconsolidation") and, with certain exceptions, will no longer be
obligated under the terms and conditions of, or entitled to the benefits of,
the Tax Allocation Agreement. Further, if TEC or TARC sells or otherwise





                                       58
<PAGE>   66
transfers any stock of TARC, or issues any options, warrants or other similar
rights relating to such stock, outside of the TNGC Consolidated Group, which
represents more than 20% of the voting power or equity value of TARC, then a
Deconsolidation of TARC would occur. A Deconsolidation of TARC would result in
a Deconsolidation of TransTexas if the TNGC Consolidated Group, excluding TARC,
does not then own at least 80% of the voting power and equity value of
TransTexas. Upon a Deconsolidation of TransTexas, members of the TNGC
Consolidated Group that own TransTexas' common stock could incur a substantial
amount of federal income tax liability. If such Deconsolidation occurred during
the fiscal year ending January 31, 1998, the aggregate amount of this tax
liability is estimated to be between $50 million and $100 million, assuming no
reduction for tax attributes of the TNGC Consolidated Group. However, such tax
liability generally would be substantially reduced or eliminated in the event
that the IRS successfully challenged TransTexas' position on the Lobo Sale.
Each member of a consolidated group filing a consolidated federal income tax
return is severally liable to the IRS for the consolidated federal income tax
liability of the consolidated group. There can be no assurance that each TNGC
Consolidated Group member will have the ability to satisfy any tax obligation
attributable to the Transactions at the time due and, therefore, other members
of the group, including TEC, TransTexas, or TARC, may be required to pay the
tax.

         Generally, under the Tax Allocation Agreement, if net operating losses
of TransTexas are used by other members of the TNGC Consolidated Group, then
TransTexas is entitled to the benefit (through reduced current taxes payable)
of such losses in later years to the extent TransTexas has taxable income,
remains a member of the TNGC Consolidated Group and the other group members
have the ability to pay such taxes. If TransAmerican, TEC, or TARC transfers
shares of common stock of TransTexas (or transfers options or other rights to
acquire such shares) and, as a result of such transfer, Deconsolidation of
TransTexas occurs, TransTexas would not thereafter receive any benefit pursuant
to the Tax Allocation Agreement for net operating losses of TransTexas used by
other members of the TNGC Consolidated Group prior to the Deconsolidation of
TransTexas.

         TransTexas is required, under the Tax Allocation Agreement, to pay any
Texas franchise tax (which is estimated not to exceed $11.4 million)
attributable to prior year transactions. TransTexas paid approximately $5.4
million of such tax as of the closing of the Lobo Sale and will pay a
substantial amount of the remaining tax within the ensuing 12-month period.

     POTENTIAL EFFECTS OF A CHANGE OF CONTROL

         The TransTexas Subordinated Notes Indenture provides that, upon the
occurrence of a Change of Control, each holder of the TransTexas Subordinated
Notes will have the right to require TransTexas to repurchase such holder's
notes at 101% of the principal amount thereof plus accrued and unpaid interest.
Pursuant to the terms of the TransTexas Intercompany Loan, upon the occurrence
of a Change of Control, TEC would have the right to require TransTexas to repay
the principal of the TransTexas Intercompany Loan in an amount equal to a pro
rata share of the amount TEC is required to pay under the Indenture. Such pro
rata share would be calculated using the ratio of the outstanding principal
amount of the TransTexas Intercompany Loan to the sum of (i) the outstanding
principal amount of the TransTexas Intercompany Loan plus (ii) the accreted
value of the outstanding principal amount of the TARC Intercompany Loan. A
Change of Control would be deemed to occur under the TransTexas Subordinated
Notes Indenture in the case of certain changes or other events in respect of
the ownership of TransTexas, including any circumstances pursuant to which any
person or group other than John R. Stanley (or his heirs, his estate or any
trust in which he or his immediate family members have, directly or indirectly,
a beneficial interest in excess of 50%) and his subsidiaries or the Trustee is
or become the beneficial owner of more than 50% of the total voting power of
TransTexas' then outstanding voting stock, and during the 90 days thereafter,
the rating of the notes is downgraded or withdrawn. A Change of Control would
be deemed to occur under the TransTexas Intercompany Loan in the case of
certain changes or other events in respect of the ownership or control of TEC,
TransTexas, or TARC including any circumstance pursuant to which (i) any person
or group, other than John R. Stanley (or his heirs, his estate or any trust in
which he or his immediate family members have, directly or indirectly, a
beneficial interest in excess of 50%) and his subsidiaries or the Trustee is or
becomes the beneficial owner of more than 50% of the total voting power of
TEC's then outstanding voting stock, or (ii) TEC or any of its subsidiaries own
some of TransTexas' or TARC's capital stock, respectively, but less than 50% of
the total voting stock or economic value of TransTexas or TARC, respectively,
unless the Notes have an investment





                                       59
<PAGE>   67
grade rating for the period of 120 days thereafter. The term "person," as used
in the definition of Change of Control, means a natural person, company,
government or political subdivision, agency or instrumentality of a government
and also includes a "group," which is defined as two or more persons acting as
a partnership, limited partnership or other group. In addition, certain changes
or other events in respect of the ownership or control of TransTexas that do
not constitute a Change of Control under the Indenture may result in a "change
of control" of TransTexas under the terms of TransTexas' credit facility (the
"BNY Facility") and certain equipment financing. Such an occurrence could
create an obligation for TransTexas to repay such other indebtedness. At July
31, 1997, TransTexas had approximately $26.6 million of indebtedness (excluding
the TransTexas Intercompany Loan and the TransTexas Subordinated Notes) subject
to such right of repayment or repurchase. In the event of a Change of Control
under the TransTexas Subordinated Notes Indenture or the Indenture or a "change
of control" under the terms of other outstanding indebtedness, there can be no
assurance that TransTexas will have sufficient funds to satisfy any such
payment obligations.

         A change of control or other event that results in deconsolidation of
TransTexas and TransAmerican for federal income tax purposes could result in
acceleration of a substantial amount of federal income taxes. These matters,
individually and in the aggregate, amount to significant potential liability
which, if adjudicated in a manner adverse to TransTexas in one reporting
period, could have a material adverse effect on TransTexas' cash flow or
operations for that period. Although the outcome of these contingencies or the
probability of the occurrence of these contingencies cannot be predicted with
certainty, TransTexas does not expect these matters to have a material adverse
effect on its financial position.

                             BUSINESS OF TRANSTEXAS

         TransTexas is engaged in the exploration for and development and
production of natural gas, primarily in South Texas. Since 1973, TransTexas has
drilled over 1,400 wells and discovered over 3.5 Tcfe of natural gas.
TransTexas' business strategy is to utilize its extensive experience gained
from over 20 years of drilling and operating wells in South Texas, to continue
to find, develop and produce reserves at a low cost. TransTexas has
traditionally performed most of its own well site preparation, drilling,
workover, completion, pipeline and production services.

         In 1994, as part of its strategy to expand its productive reserves
beyond the Lobo Trend, TransTexas began evaluating prospects that exhibited the
potential to add proved reserves of at least 50 Bcfe of natural gas per
development area. Since that time, TransTexas has evaluated over 300 potential
areas and its development of certain of these areas has resulted in substantial
additions to its reserves and production.

         In May 1997 TransTexas consummated the sale of TTC, its subsidiary
that owned substantially all of TransTexas' Lobo Trend producing properties and
related pipeline transmission system, for a sales price of approximately $1.1
billion. As of February 1, 1997, the Lobo Trend producing properties divested
by the sale of the stock of TTC had proved reserves of approximately 550 Bcfe.
As of February 1, 1997 TransTexas' net proved reserves for the Continuing
Operations, as estimated by Netherland, Sewell & Associates, were 404 Bcfe. As
of July 31, 1997, after giving effect to the Lobo Sale, TransTexas owned
approximately 650,000 gross (475,000 net) acres of mineral interests.

         TransTexas' average net daily natural gas production for the year
ended January 31, 1997, was approximately 420 MMcfd, for a total net production
of 153.6 Bcf of natural gas. After giving effect to the Lobo Sale, TransTexas'
average daily net production for the six months ended July 31, 1997 was
approximately 164 MMcfd of natural gas and 2,013 Bpd of crude oil and
condensate, for a total net production of 31.1 Bcfe.

OPERATING AREAS

         TransTexas' primary areas of operations are discussed below:

         BOB WEST NORTH. In late 1994, TransTexas made a natural gas discovery
in the Bob West North area of southern Zapata County, Texas. As of July 31,
1997, TransTexas has drilled 51 wells and completed 47 wells in the area.
TransTexas' mineral interests in Bob West North consist of a 98% working
interest in 17,700 gross (14,810 net) acres and a 90% net profits interest in
660 gross acres. The Bob West North area surpassed the Lobo Trend in net daily
natural gas production to TransTexas by the end of fiscal 1997. On July 31,
1997, TransTexas was drilling two wells in Bob West North and was in the
process of completing one well. For the six months ended July 31, 1997,
TransTexas produced 31.3 Bcf (22.7 net Bcf) from the Bob West North area for
average net daily production of 126 MMcfd. For the twelve months ended January
31, 1997, TransTexas produced 45.7 Bcf (32.6 net Bcf) from the Bob West North
area. Recent drilling results indicate the potential for a new productive fault
block of the structure that previously had not been drilled.

         FANDANGO SOUTH. TransTexas is developing an additional natural gas
discovery located in the Lower Wilcox sands in Jim Hogg County, Texas known as
the Fandango South area. As of July 31, 1997, TransTexas had drilled five
wells, and completed three wells in Fandango South. TransTexas was also
completing a fourth well and drilling 2 additional wells in the area.
TransTexas' Fandango South properties are currently producing primarily from
the Travis Ward sands of the Wilcox formation. As a result of carbon-dioxide
levels in the natural gas from this formation, production is currently
constrained by transmission pipeline carbon-dioxide standards. TransTexas is
installing amine treatment facilities to lower carbon-dioxide levels.
TransTexas is also drilling wells to the Hinnant sands of the Wilcox formation,
from which natural gas is of higher quality, and blending the production. For
the six months ended July 31, 1997, TransTexas produced 2.4 Bcf gross (1.7 Bcf
net) of natural gas from Fandango South, at an average net daily rate of 9.4
MMcfd. As of July 31, 1997, TransTexas held a 97% working interest in
approximately 5,430 gross (5,430 net) acres in Fandango South.

         GALVESTON BAY. In November 1996, TransTexas reached agreement with an
unaffiliated third party to jointly conduct exploration of geological
prospects. The parties have identified six prospects in Galveston Bay that they
intend to drill and have commenced drilling on two of these prospects.

         On September 16, 1997, TransTexas announced that it had concluded
drilling of the State Tract 331#1 well on the Eagle Point prospect in Galveston
Bay, located approximately one mile off the coast of San Leon, Texas, in a water
depth of less than ten feet. Electric logs indicated the presence of high
quality hydrocarbon-bearing pay. TransTexas had previously encountered
difficulties with controlling the wellbore pressure when drilling through the
potential pay zone, and recovered low gravity condensate in the drilling returns
from the zone. TransTexas intends to conduct a flow test of the State Tract
331#1 well as soon as practicable. TransTexas owns a 75% working interest
covering approximately 2,800 gross acres (2,640 net acres) in the area.

         TransTexas is also drilling a second well, the State Tract 88A#1, in
Galveston Bay on the Virginia Point Prospect. TransTexas owns a 75% working
interest in approximately 2,760 gross acres (2,490 net acres) in the Virginia
Point prospect.

         TransTexas owns a 75% working interest in a total of 9,430 gross acres
(6,890 net acres) in four other prospects in the Galveston Bay area that it
intends to drill.

         GOLIAD & VICTORIA COUNTIES. TransTexas entered into an agreement with
an unaffiliated third party to develop 3- D seismic prospects in Goliad and
Victoria Counties, Texas. The discovery well, the Strong #1, which logged 82
net feet of pay from five zones between the depths of 10,800 and 13,800 feet,
has been flowing into a third-party pipeline since August 16, 1997. The well,
which is temporarily constrained by pipeline capacity to 5 MMcfd, has flowed at
a rate of 7.6 MMcfd.

         Recently, drilling of a key delineation well, the Dorris #2, was
completed and electric logs have indicated the presence of multiple pay zones.
TransTexas expects to complete this well and commence production by early
October 1997. An earlier well, the Dorris #1, was lost due to mechanical
problems that resulted from a tubular failure. TransTexas expects to complete
two additional wells in Goliad County, the Strong #2 and Dorris #3, in October.
TransTexas is also drilling the Huber #1 in adjacent Victoria County, in what
is believed to be an extension of the prospect. TransTexas owns a 100% working
interest in approximately 4,240 gross acres (3,180 net acres) in Goliad and
Victoria Counties.

         WHARTON COUNTY. In 1995, TransTexas entered into an agreement with an
unaffiliated third party to jointly develop the mineral rights in Frio and
Miocene sands in Wharton County, Texas. TransTexas is not the operator of this
interest but interprets data from a dedicated 3-D seismic program to select
drilling locations in which prior production has not depleted the shallow
reservoirs. As of July 31, 1997, 51 wells had been drilled in shallow
formations in the area, 22 of which had been completed. For the six months
ended July 31, 1997, TransTexas' Wharton County properties produced 2.1 Bcf
(1.4 Bcf net) of natural gas at an average gross daily rate of 11.6 MMcfd (7.5
MMcfd net).

         TransTexas also acquired mineral rights covering deep prospective
production of the Wilcox formation in Wharton County. TransTexas has drilled and
completed two wells, the Joel Hudgins #1 and the Guenther #1, and is finalizing
pipeline transmission arrangements. The Joel Hudgins #1 well began production on
August 25, 1997 at a rate of 4.0 MMcfd. The Gunther #1, located three miles
northwest of the Joel Hudgins #1, has flow tested at a rate of 5.3 MMcfd from 65
feet of net pay and is awaiting a pipeline connection to a carbon-dioxide
treatment plant. A third well, the Rees-Gifford #1, is located approximately 14
miles southwest of the Joel Hudgins #1, and has logged a total of 75 feet of net
Wilcox pay. As of July 31, 1997, TransTexas held a 75% working interest in the
shallow mineral rights in approximately 43,110 gross (34,570 net) acres in
Wharton County and a 100% working interest in the deep mineral rights in
approximately 2,580 gross (2,570 net) acres.

         LODGEPOLE, NORTH DAKOTA. In late 1996, TransTexas announced the
discovery of a Lodgepole carbonate reef oil field in Dickinson, North Dakota
with the Heart River #1, which flow tested at a daily rate of 6,836 Bpd.
TransTexas has conducted or participated in a series of 3-D seismic surveys
covering more than 270 square miles in Stark and Dunn counties, North Dakota.
TransTexas holds an average working interest of 80% in approximately 198,800
gross (98,400 net) acres in the Lodgepole. As of July 31, 1997, TransTexas had
drilled a total of eleven wells in the Lodgepole, three of which had been
completed. Effective March 1997, all producing wells in the field are
restricted to a State-mandated allowable daily rate of approximately 500 Bpd
per well. In the six months ended July 31, 1997, TransTexas' Lodgepole
properties produced 481,450 barrels of crude oil (308,130 barrels net) at a
gross average daily rate of 2,660 Bpd (1,702 Bpd net).

         TransTexas believes that its interests in the Lodgepole do not fit its
long term strategic plan as a core producing property. In September 1997
TransTexas engaged First Union Corporation to solicit interest in its Lodgepole
properties, with the ultimate intent of divesting its producing properties in
North Dakota.

         OTHER AREAS. TransTexas has also made discoveries of natural gas and
oil in other prospects that, as of July 31, 1997, have undergone less
development drilling, but which management believes could add material reserves
and production.

         TransTexas has entered into a separate venture with its Galveston Bay
co-venturer covering prospects in South Louisiana. TransTexas owns a 25%
working interest in a discovery well in Vermillion Parish that is currently
being completed for production. TransTexas' strategy in South Louisiana is to
interpret 3-D seismic data and develop exploration prospects for drilling.
TransTexas expects eventually to participate in more than 350 square miles of
3-D data. As of September 25, 1997, TransTexas believes that it has identified
eight individual exploration prospects in South Louisiana that it intends to
drill and as of July 31, 1997, owned a 69% working interest in 13,180 gross
acres (9,840 net acres).

         TransTexas owns an 82% working interest in 1,320 gross acres (790 net
acres) in Brazoria County, Texas. As of July 31, 1997, TransTexas was drilling
a test well in an area adjacent to existing production areas.

         TransTexas owns a 100% working interest in 5,180 gross acres (2,690
net acres) in Chambers County. Texas. As of July 31, 1997, TransTexas had
drilled two wells in Chambers County that it was completing and was in the
process of drilling two additional wells.

         TransTexas owns a 94% working interest in approximately 6,960 gross
(3,190 net) acres in Wayne County, Mississippi, in which it has drilled and
completed two wells. As of July 31, 1997, TransTexas was completing a third
well. For the six months ended July 31, 1997, TransTexas' properties in
Mississippi produced 2,480 barrels of condensate (1,740 barrels net) at a gross
average daily rate of 14 Bpd (10 Bpd net).

         TransTexas holds a 92% working interest in approximately 35,270 gross
(32,370 net) acres in the Cuba Libre area of Webb County, Texas. For the six
months ended July 31, 1997, TransTexas produced 1.3 Bcf (.8 Bcf net) at an
average daily rate of 7.0 MMcfd (4.7 MMcfd net) from a total of 20 wells
drilled in Cuba Libre, of which 10 wells had been completed by TransTexas.

         In 1996 TransTexas implemented a strategy consisting of the evaluation
of the potential for horizontal drilling in the Austin Chalk Formation. As of
July 31, 1997, TransTexas had drilled two horizontal wells in Walker County,
Texas and held a 100% working interest in approximately 54,390 gross (52,210
net) acres in the Austin Chalk.

<PAGE>   71
         TransTexas holds a 95% working interest in approximately 103,460 gross
(81,890 net) acres in the La Grulla area of Starr County, Texas. As of July 31,
1997, TransTexas had drilled a total of 34 wells in La Grulla, of which 17
wells had been completed. For the six months ended July 31, 1997, TransTexas'
La Grulla properties produced 1.3 Bcf (1.0 Bcf net) at an average rate of 7.0
MMcfd (5.4 MMcfd net).

EXPLORATION AND PRODUCTION OPERATIONS

         The exploration and production activities of TransTexas consist of
geological evaluation of current and prospective leased properties, the
acquisition of mineral leases or other interests in prospects and the
development and operation of leased properties for the production and sale of
natural gas, condensate and crude oil. TransTexas focuses upon adding proved
reserves of at least 50 Bcfe per development area. TransTexas' technical staff
consists of geologists, geophysicists and engineers whose prognoses of drilling
locations may be enhanced with the use of 3-D seismic workstations, which
TransTexas owns and operates at its Houston headquarters. TransTexas' technical
staff selects drilling locations based on either 3-D or 2-D seismic data
interpretation and their knowledge of well control from drilling experience in
the area. TransTexas operates substantially all of its producing properties.
TransTexas believes that this experience is especially important in South
Texas, which is geologically complex.

         During the five years ended January 31, 1997, TransTexas completed
approximately 78% of 591 wells drilled at an average finding cost of
approximately $0.76 per Mcfe. As of September 25, 1997, TransTexas was drilling
13 gross wells (13 net wells). As of July 31, 1997, TransTexas had a total of
99 producing wells. TransTexas had a working interest in the following numbers
of wells that were drilled during the periods indicated:

(1)      Net gas production volume for the year ended January 31, 1997, and the
         six months ended July 31, 1997, includes 32.0 Bcf and 7.3 Bcf,
         respectively, delivered to third parties under volumetric production
         payments.

(2)      Average prices for the year ended January 31, 1997, and the six months
         ended July 31, 1997, includes prices for amounts delivered to third
         parties under volumetric production payments. The average gas price
         for TransTexas' undedicated production for these periods were $2.39
         and $1.91 per Mcf, respectively. The gas prices do not include the
         effect of hedging.

DRILLING SERVICES DIVISION

         TransTexas currently performs substantially all of its own drilling
and oil field services through its drilling services division, which has an
extensive operating history in South Texas and utilizes operating processes
developed as an integrated division of TransTexas for the past 12 years. During
the fiscal year ended January 31, 1997, TransTexas drilled 151 wells,
substantially all of which were drilled by this division. The activities that
this division performs for TransTexas include drilling, oil and natural gas
well workover and completion services, as well as a variety of other support
services required for the successful exploration and production of natural gas.

         As of September 30, 1997, the assets of this division included 25 land
drilling rigs, nine workover rigs and two fracture stimulation fleets.
Complementary drilling, completion and workover service equipment includes a
ready-mix concrete plant, twin cementing trucks, a coiled tubing unit, a
snubbing unit, electric line and logging units, slickline units, tag units and
an extensive fleet of construction, inspection and other rolling stock.





                                       65
<PAGE>   73
         Increased activity in the contract drilling industry and related oil
services businesses has led to improved market valuations for contract drilling
and oil services companies. To capitalize on these trends, TransTexas may
contribute the assets of its drilling services division to its wholly owned
subsidiary, TTXD. TTXD is expected to be an integrated provider of a broad
range of oil field services including contract drilling, oil and natural gas
well workover, stimulation and completion, drilling fluids provision, pipeline
construction, trucking services, equipment repair and rental, tubular
inspection, pumping services, snubbing services, open hole logging and
maintenance services. TransTexas is evaluating alternatives to maximize
stockholder value with respect to TTXD, including options such as a spin-off, a
sale to a third party, a merger or another business combination. In connection
with the Lobo Sale, TransTexas has entered into a long-term agreement, which
can be transferred to TTXD, pursuant to which it would provide drilling and
certain other services to the new operator of the Lobo Trend properties
divested in the Lobo Sale. TransTexas has also recently begun to provide
drilling services to other third parties.

NATURAL GAS TRANSPORTATION

         As part of the Lobo Sale, TransTexas divested the majority of its
pipeline assets. Effective March 1, 1997, TransTexas entered into two
agreements with Lobo Pipeline Company for intrastate and interstate gas
transportation from its Bob West North field to the Agua Dulce marketing hub or
to the Exxon King Ranch for gas processing. The agreements are for a term of
approximately ten years and allow for the transportation of up to a combined
total of 400 MMcf per day. TransTexas has retained ownership of its pipeline
systems within the Bob West North and Fandango South fields. TransTexas
believes that there is currently adequate pipeline transportation capacity for
TransTexas' hydrocarbon production in all of its operating areas. TransTexas
intends to build additional pipeline capacity as future needs require. However,
there can be no assurance that TransTexas will have funds available to build
additional pipeline capacity.

RESERVES

         The following table sets forth certain information with respect to
TransTexas' proved reserves and the present value (discounted at 10%) of
estimated future net revenues before income taxes, as estimated by Netherland
Sewell, TransTexas' independent petroleum engineers, as of the dates indicated.
For additional information regarding TransTexas' proved reserves at February 1,
1997, see the reports of Netherland Sewell attached as Annex B to this
Prospectus.

- --------------------

(1)      Excludes approximately 47 Bcf and 43 Bcf as of February 1, 1997 and
         1996, respectively, attributable to volumetric production payments.

(2)      Before income taxes.

(3)      Gives effect to the Lobo Sale.

         In accordance with applicable guidelines of the Commission, the
estimates of TransTexas' proved reserves and future net revenues therefrom set
forth herein are made using gas, condensate and oil sales prices in effect as
of the date of such reserve estimates and are held constant throughout the life
of the properties (except for fixed and determinable price escalations as
provided by contract). Estimated quantities of proved reserves and future net
revenues therefrom are affected by changes in gas, condensate and oil prices.
Prices have fluctuated widely in recent years. TransTexas has entered into
hedging transactions to mitigate a portion of such natural gas price
volatility. As of August 1, 1994 and 1995, February 1, 1996 and 1997, and as of
February 1, 1997 after giving effect to the Lobo Sale, the sales prices used
for purposes of estimating TransTexas' proved reserves and the future net
revenues from those reserves were $1.62, $1.37, $1.95, $3.17 and $3.03 per Mcf,
respectively, and $17.62, $16.27, $18.34, $23.99 and $24.13 per Bbl of
condensate and crude oil, respectively. During the quarter ended July 31, 1997,
average gas prices for the Continuing Operations were significantly lower than
$3.03.

         Proved reserves are the estimated quantities of natural gas,
condensate and oil that geological and engineering data demonstrate with
reasonable certainty to be recoverable in future years from known reservoirs
under existing economic and operating conditions. Proved developed reserves are
proved reserves that can be expected to be recovered through existing wells
with existing equipment and operating methods. The estimation of reserves
requires substantial judgment on the part of petroleum engineers, resulting in
imprecise determinations, particularly with respect to recent discoveries. The
accuracy of any reserve estimate depends on the quality of available data and
engineering and geological interpretation and judgment. Results of drilling,
testing and production after the date of the estimate may





                                       67
<PAGE>   75
result in revisions of the estimate. Accordingly, estimates of reserves are
often materially different from the quantities of natural gas, condensate and
oil that are ultimately recovered, and these estimates will change as future
production and development information becomes available. The reserve data
represent estimates only and should not be construed as being exact.

         The present value of estimated future net revenues relating to proved
reserves are presented in accordance with the provisions of Statement of
Financial Accounting Standards No. 69, "Disclosures about Oil and Gas Producing
Activities," except income taxes have been omitted. In computing these data,
assumptions and estimates have been used, and TransTexas cautions against
viewing this information as a forecast of future economic conditions. The
future net revenues are determined by using estimated quantities of proved
reserves and the periods in which they are expected to be developed and
produced based on economic conditions at the date of the estimates. The
estimated future production is based on prices in effect at the date of the
estimates, except where fixed and determinable price escalations are provided
by contract. The resulting estimated future gross revenues are reduced by
estimated future costs to develop and produce the proved reserves based on cost
levels in effect at the date of the estimates, but not for debt service, income
taxes and general and administrative expenses (except to the extent such
general and administrative expenses constitute overhead costs incurred at the
district or field level that are allowed under joint operating agreements). The
present value of proved reserves set forth herein should not be construed as
the current market value of the estimated proved reserves attributable to
TransTexas' properties.

TITLE TO PROPERTIES

         As is customary in the oil and gas industry, TransTexas performs only
a preliminary title investigation before leasing undeveloped properties.
Accordingly, working interest percentages and gross and net acreage set forth
herein for undeveloped properties are preliminary. However, a title opinion is
obtained before the commencement of drilling operations and any material
defects in title are remedied prior to the time actual drilling of a well on
the lease is commenced. TransTexas believes that it has satisfactory title to
developed properties in accordance with standards generally accepted in the oil
and gas industry. TransTexas' properties are subject to customary royalty
interests, liens incident to operating agreements, liens for current taxes and
other burdens which TransTexas believes do not materially interfere with the
use of or affect the value of such properties. In addition, several litigants
against TransTexas have filed claims that affect certain of TransTexas'
properties. TransTexas does not expect these claims to interfere with the use
of, or affect the value of, its properties in any material way.

ACREAGE

(1)      Productive wells consist of producing wells and wells capable of
         production, including gas wells awaiting pipeline connection. Of the
         total productive wells, 96 gross (94 net) were gas wells and three
         gross (two net) were oil wells. Wells that are completed in more than
         one producing zone are counted as one well. As of July 31, 1997,
         TransTexas had interests in a total of 99 productive wells, six of
         which had multiple completions.





                                       68
<PAGE>   76
NATURAL GAS MARKETING

         TransTexas sells its natural gas on the spot market on an
interruptible basis or pursuant to long-term contracts at market prices.

         TransTexas and MidCon Texas Pipeline Corp. ("MidCon") entered into a
long-term gas purchase contract on January 10, 1996, under which TransTexas is
required to deliver a total of 100,000 MMBtu per day to four specified delivery
points for a period of five years. The purchase price is determined by an
industry index less $0.09 per MMBtu. Deliveries commenced on September 1, 1996.
In connection with this transaction, TransTexas built a 24-inch pipeline for
MidCon that spans approximately 68 miles from the Bob West North field to
MidCon's 30-inch pipeline in Webb County, Texas. Pursuant to a related
agreement, TransTexas will earn a 50% interest in a 28-mile segment of the new
pipeline after five years.

HEDGING

         From time to time, TransTexas has entered into commodity price swap
agreements (the "Hedge Agreements") to reduce its exposure to price risk in the
spot market for natural gas. For the fiscal year ended January 31, 1997, and
six months ended July 31, 1997, TransTexas made net settlement payments
totaling approximately $37 million and $7.4 million, respectively, to the
counterparty pursuant to the Hedge Agreements. As of July 31, 1997, TransTexas
had no active Hedge Agreements. The Hedge Agreements are accounted for as
hedges and, accordingly, any gains and losses are deferred and recognized in
the respective month as physical volumes are sold.

COMPETITION

         TransTexas encounters intense competition from major oil and gas
companies and independent operators in the acquisition of desirable undeveloped
natural gas leases and in the sale of natural gas. Many of its competitors are
large, well-established companies with substantially larger operating staffs
and greater capital resources than TransTexas' and which, in many instances,
have been engaged in the energy business for a much longer time than
TransTexas.

         The primary bases for competition in the natural gas and oil
exploration and production businesses are the costs involved in the finding and
development of such resources combined with commodity sales prices and market
access. TransTexas places considerable emphasis upon the expertise of its
exploration personnel and believes that its strategy of seeking undeveloped
acreage that it believes holds exploration and production potential allows it
to leverage this expertise into low finding and development costs.

EMPLOYEES

         As of September 30, 1997, TransTexas had approximately 2,660
employees, including approximately 2,200 field employees related to its natural
gas exploration, production and service businesses. TransTexas will employ
additional personnel as required by its operations and may engage the services
of independent geological, engineering, land and other consultants from time to
time. None of TransTexas' employees are parties to a collective bargaining
agreement.

GOVERNMENTAL REGULATION

         TransTexas' gas exploration, production and related operations are
subject to extensive rules and regulations promulgated by federal and state
agencies. Failure to comply with such rules and regulations can result in
substantial penalties. The regulatory burden on the gas industry increases
TransTexas' cost of doing business and affects its profitability. Because such
rules and regulations are frequently amended or reinterpreted, TransTexas is
unable to predict the future cost or impact of complying with such laws.





                                       69
<PAGE>   77
         The State of Texas (through the Texas Railroad Commission) and many
other states, including North Dakota, require permits for drilling operations,
drilling bonds and reports concerning operations, and impose other requirements
related to the exploration and production of gas. Such states also have
statutes or regulations addressing conservation matters, including provisions
for the unitization or pooling of gas properties, the establishment of maximum
rates of production from oil or gas wells and the regulation of spacing,
plugging and abandonment of such wells. The statutes and regulations of the
State of Texas limit the rate at which gas can be produced from TransTexas'
properties. However, these statutes and regulations have not materially
impacted TransTexas' results of operations; however, there can be no assurance
that such statutes and regulations will not affect TransTexas' operating
results in the future.

         Several major regulatory changes have been implemented by the Federal
Energy Regulatory Commission ("FERC") since 1985 that affect the economics of
natural gas production, transportation and sales. In addition, the FERC
continues to promulgate revisions to various aspects of the rules and
regulations affecting those segments of the natural gas industry, most notably
interstate natural gas transmission companies, that remain subject to the
FERC's jurisdiction. These initiatives may also affect the intrastate
transportation of gas under certain circumstances. The stated purpose of many
of these regulatory changes is to promote competition among the various sectors
of the gas industry. The ultimate impact on TransTexas of these complex and
overlapping rules and regulations, many of which are repeatedly subjected to
judicial challenge and interpretation, cannot be predicted.

ENVIRONMENTAL MATTERS

         TransTexas' operations and properties are subject to extensive
federal, state and local laws and regulations relating to the generation,
storage, handling, emission, transportation and discharge of materials into the
environment. Permits are required for various of TransTexas' operations, and
these permits are subject to revocation, modification and renewal by issuing
authorities. TransTexas also is subject to federal, state and local laws and
regulations that impose liability for the cleanup or remediation of property
that has been contaminated by the discharge or release of hazardous materials
or wastes into the environment. Governmental authorities have the power to
enforce compliance with their regulations, and violations are subject to fines
or injunctions, or both. Certain aspects of TransTexas' operations may not be
in compliance with applicable environmental laws and regulations, and such
noncompliance may give rise to compliance costs and administrative penalties.
It is not anticipated that TransTexas will be required in the near future to
expend amounts that are material to the financial condition or operations of
TransTexas by reason of environmental laws and regulations, but because such
laws and regulations are frequently changed and, as a result, may impose
increasingly strict requirements, TransTexas is unable to predict the ultimate
cost of complying with such laws and regulations.

LEGAL PROCEEDINGS

         ALAMEDA. On May 22, 1993, Alameda Corporation ("Alameda") sued
TransAmerican in the 234th Judicial District Court, Harris County, Texas,
claiming that TransAmerican failed to account to Alameda for a share of the
proceeds TransAmerican received in a 1990 settlement of litigation with El Paso
Natural Gas Company ("El Paso"), and that TransAmerican has been unjustly
enriched by its failure to share such proceeds with Alameda. On September 20,
1995, the jury rendered a verdict in favor of TransAmerican. Alameda appealed
to the Fourteenth Court of Appeals, which affirmed the trial court judgment in
favor of TransAmerican. Alameda filed a motion for rehearing on April 10, 1997
and TransAmerican responded. The court denied Alameda's motion, and Alameda has
appealed to the Texas Supreme Court.

         ASPEN. TransAmerican brought suit on September 29, 1993 against Aspen
Services, Inc. ("Aspen"), seeking an audit and accounting of drilling costs
that Aspen had charged while providing drilling services to TransAmerican. This
suit is pending in the 215th Judicial District Court, Harris County, Texas. The
parties' drilling agreement provided, among other things, that Aspen would
receive payment for its drilling-related costs from the production and sale of
gas from the wells that were drilled, and that the revenues that TransAmerican
would otherwise receive from the wells would be reduced by the amounts received
by Aspen. On July 19, 1995, Aspen filed a counterclaim and third party claim
against TransAmerican, TransTexas, and affiliated entities, asserting, among
other things, that these entities failed





                                       70
<PAGE>   78
to make certain payments and properly market the gas from these wells. Aspen
sought damages in an unspecified amount, as well as certain equitable claims.
In April 1997, the trial court ruled against Aspen on all of its claims and
counterclaims.

         BRIONES. In an arbitration proceeding, Jesus Briones, a lessor,
claimed that one of TransTexas' wells on adjacent lands had been draining
natural gas from a portion of his acreage leased to TransTexas on which no well
had been drilled. On October 31, 1995, the arbitrator decided that drainage had
occurred. On June 3, 1996, the arbitrator issued a letter indicating that
drainage damages would be awarded to Briones in the amount of approximately
$1.4 million. The arbitrator entered his award of damages on June 27, 1996. On
July 3, 1996, TransTexas filed a petition in the 49th Judicial District Court,
Zapata County, Texas, to vacate the arbitrator's award. Briones also filed a
petition to confirm the arbitrator's award. In April 1997, the court granted
Briones' motion for summary judgment. In August 1997, the court entered a final
judgment for Briones in the amount of approximately $1.6 million. TransTexas
has filed a motion for new trial.

         FINKELSTEIN. On April 15, 1990, H.S. Finkelstein filed suit against
TransAmerican in the 49th Judicial District Court, Zapata County, Texas,
alleging that TransAmerican failed to pay royalties and improperly marketed oil
and gas produced from certain leases. On September 27, 1994, the plaintiff
added TransTexas as an additional defendant. On January 6, 1995, a judgment
against TransAmerican and TransTexas was entered for approximately $18 million
in damages, interest and attorneys' fees. TransTexas and TransAmerican appealed
the judgment to the Fourth Court of Appeals, San Antonio, Texas, which affirmed
the judgment on April 3, 1996. TransTexas and TransAmerican filed a motion for
rehearing. On August 14, 1996, the Fourth Court of Appeals reversed the trial
court judgment and rendered judgment in favor of TransAmerican and TransTexas.
On August 29, 1996, Finkelstein filed a motion for stay and a motion for
rehearing with the court. On October 9, 1996, the court denied Finkelstein's
rehearing request. In November 1996, Finkelstein filed an application for writ
of error with the Supreme Court of Texas.

         On April 22, 1991, Finkelstein filed a separate suit against
TransAmerican and various affiliates in the 49th Judicial District Court,
Zapata County, Texas, alleging an improper calculation of overriding royalties
allegedly owed to the plaintiff and seeking damages and attorneys' fees in
excess of $33.7 million. On November 18, 1993, the plaintiff added TransTexas
as an additional defendant. The parties arbitrated this matter in January 1997.
A partial decision from the arbitration panel has been rendered in favor of
Finkelstein. Although the amount of damages has yet to be determined under the
panel's decision, such amount will be substantially less than that sought by
plaintiff.

         ARABIAN OFFSHORE PARTNERS. On June 27, 1997, Arabian Offshore Partners
filed a lawsuit against TransTexas in the 14th Judicial District Court, Dallas
County, Texas, seeking $20 million in damages in connection with TransTexas'
refusal to proceed with the acquisition of two jack-up drilling rigs.
TransTexas has filed its answer and is preparing a motion for summary judgment.

         GENERAL. TransTexas is also a named defendant in other ordinary
course, routine litigation incidental to its business. Although the outcome of
these other lawsuits cannot be predicted with certainty, TransTexas does not
expect these matters to have a material adverse effect on its financial
position. At July 31, 1997, the possible range of estimated losses related to
all of the aforementioned claims, in addition to the estimates accrued by
TransTexas is $0 to $36 million. The resolution in any reporting period of one
or more of these matters in a manner adverse to TransTexas could have a
material impact on TransTexas' results of operations and cash flows for that
period. Litigation expense, including legal fees, totaled approximately $9.4
million and $7.3 million for the six months ended July 31, 1997 and 1996.

                                BUSINESS OF TARC

GENERAL

         TARC was formed in 1987 to hold and operate the refinery assets of
TransAmerican and is engaged in the refining and storage of crude oil and
petroleum products. TransAmerican acquired the refining facility in 1971 and,
between 1978 and 1983, invested approximately $900 million in capital
improvements to expand capacity and increase refining complexity. In January
1983, financial difficulties prevented TransAmerican from completing certain
units of the refinery and forced a shutdown of operations. From 1983 to August
1993, TransAmerican and TARC spent approximately $125 million on maintenance
and capital expenditures at the refinery.

         TARC's business strategy is to modify, expand and reactivate its
refinery and to maximize its gross refining margins by converting low-cost,
heavy, sour crude oils into high-value, light petroleum products, including
primarily gasoline and heating oil. In February 1995, TARC began a construction
and expansion program designed to reactivate the refinery and increase its
complexity. From February 1, 1995 through April, 1997, TARC spent approximately
$245 million on this program, procured a majority of the essential equipment
required and completed substantially all of the process design engineering and a
substantial portion of the remaining engineering necessary to complete this
project.

         TARC will receive approximately $427 million in proceeds pursuant to
the Transactions to pursue the Capital Improvement Program, which is designed
to reactivate the refinery and increase its complexity. The design and
estimated timing and cost of the Capital Improvement Program are based on
substantial input from several prominent engineering and construction firms
(including ABB Lummus Crest, Inc., Belco Technologies Corporation, Fluor
Daniel, Inc., Black & Veatch Pritchard Inc., Stratco Inc., Raytheon Engineers &
Constructors and PCI Engineers, Inc.). TARC has contracted with these firms
during the past two years to perform design engineering and construction
management services. Phase I of the Capital Improvement Program includes the
completion and start-up of several units, including the Delayed Coking Unit,
one of the refinery's major conversion units. TARC estimates that Phase I will
be completed at a cost of $223 million, will be tested and operational by
September 30, 1998 and will result in the refinery having the capacity to
process up to 200,000 Bpd of sour crude oil. Phase II of the Capital
Improvement Program includes the completion and start-up of the Fluid Catalytic
Cracking Unit utilizing state-of-the-art MSCC(SM) technology and the
installation of additional equipment expected to further improve operating
margins by allowing for a significant increase in the refinery's capacity to
produce gasoline. TARC estimates that Phase II will be completed at a cost of
$204 million and will be tested and operational by July 31, 1999. After
completion of the Capital Improvement Program, TARC will own and operate one of
the largest independent refineries in the Gulf Coast region, with a replacement
cost estimated by management to be approximately $1.4 billion. The foregoing
estimates, as well as other estimates and projections herein, are subject to
substantial revision upon the occurrence of future events, such as
unavailability of financing, engineering problems, work stoppages and cost
overruns, over which TARC may not have any control, and there can be no
assurance that any such projections or estimates will prove accurate.

INDUSTRY OVERVIEW

         Total growth in United States refining capacity has remained very low
over the past several years. Over the same period, however, demand for refined
products has substantially increased. As a result, capacity utilization has
increased to approximately 93.5% in 1996 from approximately 77.6% in 1985,
reflecting the significant increase in demand for refined products. The
refinery utilization rate is an important factor in achieving and maintaining
refining profitability. Management of TARC believes that over the next several
years domestic demand for refined products will continue to increase while
refining capacity growth will remain slow, causing United States refining
utilization rates to remain high. In addition, management of TARC believes that
increased foreign demand, particularly in the Far East, combined with more
stringent domestic product specifications, should limit the availability of
imported refined products. Management believes that these factors, together
with relatively low prices expected by it for heavy, sour crude oil, should
have a positive effect on TARC's refining margins.

BACKGROUND OF THE REFINERY

         Operations at TARC's refining site began in 1967 with the installation
of a 7,000 Bpd "topping" facility to process light crude and condensate
available in South Louisiana. A few years later, a 4,000 Bpd naphtha reformer
was added and crude processing capacity was increased to 10,000 Bpd of light,
sweet crude. In 1971, TransAmerican purchased the refinery and over the next
eight years expanded it to 100,000 Bpd of medium, sour crude capacity, and
added significant additional downstream processing. In 1979, TransAmerican
began an expansion and modernization program in response to a need for
additional United States refining capacity. This program was designed to permit
the refinery to process up to 300,000 Bpd of heavy, sour crude oil into a high
proportion of high-value, light petroleum products.

         In 1982, high oil prices and a general economic recession led to
reduced product demand and a large surplus of refining capacity, which in turn
caused a significant drop in refining margins. In addition, TransAmerican's
cash flow was adversely affected by reduced sales to natural gas customers due
to proration and by the interest expense on its floating rate debt, which
exceeded 20%. As a result, in January 1983, before completion of the
construction program and after expenditures of approximately $900 million,
these financial difficulties prevented completion of a delayed coking unit and
certain other units of the refinery necessary to economically process heavy,
sour crude oil, and forced a shutdown of operations.

CURRENT OPERATIONS

         In March 1994, TARC commenced partial operations at the refinery with
the start-up of the No. 2 Vacuum Unit. This unit has been operating
intermittently since that time. Modifications and tie-ins to the No. 2 Crude
Unit have been completed. Although both units are operational, TARC is not
currently operating these units due to the low level of operating margins
obtainable for these units on a stand-alone basis. TARC currently has one cargo
in its inventory.

         The following is a brief description of TARC's No. 2 Vacuum Unit and
No. 2 Crude Unit:

         NO. 2 VACUUM UNIT. TARC believes that the No. 2 Vacuum Unit has a
capacity in excess of 200,000 Bpd. TARC reactivated the No. 2 Vacuum Unit in
March 1994. The No. 2 Vacuum Unit is designed to process atmospheric tower
bottoms into VGO and, with the addition of cutterstocks, into No. 6 residual
fuel oil. When the No. 2 Crude Unit is placed into operation, the No. 2 Vacuum
Unit will process bottoms from the No. 2 Crude Unit. When the Delayed Coking
Unit is complete, the No. 2 Vacuum Unit tower bottoms are expected to be
processed through the Delayed Coking Unit into lighter, more valuable products.
Upon completion of Phase II, VGO is expected to be upgraded in the Fluid
Catalytic Cracking Unit to gasoline and No. 2 fuel oil.

         NO. 2 CRUDE UNIT. The No. 2 Crude Unit was designed to process heavy,
sour crude oil and, prior to the 1983 shutdown, demonstrated a capacity of
175,000 Bpd. Upon completion of the Capital Improvement Program, the No. 2
Crude Unit is expected to process up to 200,000 Bpd of a mix of crude oils into
naphtha, kerosene, No. 2 fuel oil, atmospheric gas oil and atmospheric residual
oil.

CAPITAL IMPROVEMENT PROGRAM

         The Capital Improvement Program is designed to increase the capacity
and complexity of the refinery. The most significant projects include: (i)
conversion of the visbreaker unit to a delayed coking unit to process vacuum
tower bottoms into lighter petroleum products, (ii) modernization and upgrade
of a fluid catalytic cracking unit to increase gasoline production capacity and
allow the direct processing of low cost atmospheric residual feedstocks and
(iii) upgrading and expanding hydrotreating, alkylation and sulfur recovery
units to increase sour crude processing capacity. In addition, TARC plans to
expand, modify and add other processing units, tankage and offsite facilities
as part of the Capital Improvement Program. The Capital Improvement Program
includes expenditures necessary to ensure that the refinery is in compliance
with certain existing air and water discharge regulations and that gasoline
produced will comply with federal standards. TARC will act as general
contractor, but has engaged a number of specialty consultants and engineering
and construction firms to assist TARC in completing the individual projects
that comprise the Capital Improvement Program. Each of these firms was selected
because of its specialized expertise in a particular process or unit integral
to the Capital Improvement Program.

         The Capital Improvement Program will be executed in two phases,
described as follows:

PHASE I

         Phase I includes the Delayed Coking Unit, the HDS Unit, the Naphtha
Pretreater, the No. 2 Reformer, both Sulfur Plants and the supporting Offsite
Facilities. Completion of Phase I, along with the Crude and Vacuum Units, will
enable the refinery to process heavy crude and purchased feedstocks into
finished and intermediate products. Products from this phase are expected to
include NGLs, naphtha, conventional gasoline, No. 2 fuel oil, VGO, sulfur and
petroleum coke. The following is a brief description of the units and offsite
facilities that are scheduled to be added or improved during Phase I and TARC's
plans and expectations therefor:

         DELAYED COKING UNIT. TARC's Visbreaking Unit is being converted to a
Delayed Coking Unit. The process engineering for this conversion has been
completed by ABB Lummus Crest Inc. Detailed design engineering has been
substantially completed by INDTECH INC., and all major equipment has been
purchased and installed. Fluor Daniel, Inc. will manage the remaining
construction, which will consist primarily of the installation of piping and
instrumentation systems. Field construction is approximately 55% complete. The
Delayed Coking Unit is expected to be able to process approximately 75,000 Bpd
of vacuum tower bottoms produced from the No. 2 Vacuum Unit. Products from this
unit will include light gas, naphtha, coker distillate, and coker gas oil,
which can all be further upgraded by TARC's refinery or sold to other refiners
for upgrading.

         NAPHTHA PRETREATER. TARC has purchased a used naphtha pretreater,
which it has disassembled and moved to the refinery site. The process
engineering for this unit has been completed by PCI Engineers Inc., and total
engineering is approximately 50% complete. Construction has commenced with the
installation of piling and foundations. Upon re- assembly, this unit will
produce desulfurized heavy naphtha, to be processed by the No. 2 Reformer into
reformate for blending into gasoline, and light naphtha for gasoline blending
or sales. The Naphtha Pretreater is designed to process up to 30,000 Bpd of
naphtha feedstock produced by the No. 2 Crude Unit and the Delayed Coking Unit.

         NO. 2 REFORMER. The No. 2 Reformer was purchased by TARC's predecessor
and relocated to the refinery during the 1980s expansion. Although re-assembly
is not complete, all major equipment is installed. PCI Engineers Inc. is
performing the process and detailed design engineering. Field construction will
include reconditioning of equipment plus installation of piping and
instrumentation systems. The No. 2 Reformer will process desulfurized heavy
naphtha to raise its octane level to that suitable for gasoline blending. The
unit is designed to process up to 12,000 Bpd of feedstock to produce high
octane reformate for gasoline blending. This unit will also provide a portion
of the hydrogen required for operation of the Naphtha Pretreater and the HDS
Unit.





                                       74
<PAGE>   82
         HYDRODESULFURIZATION (HDS) UNIT. In the early 1980s, TARC's
predecessor designed and commenced construction of a two-train distillate HDS
Unit with a common fractionation section. During Phase I, TARC will install two
new reactors, both of which have been purchased and fabricated, and add another
fractionation section to permit independent operation of both trains. Other
major equipment required is in place. When completed, each train will be
capable of treating either distillate or VGO depending on unit or product
requirements.

         SULFUR RECOVERY SYSTEM. Sulfur is captured in various refining
processes, primarily cracking and hydrodesulfurization, in the form of hydrogen
sulfide which is absorbed into an amine solution or into sour water streams.
The hydrogen sulfide is stripped from these streams and processed in a series
of reactors into elemental sulfur. TARC will reactivate and expand an existing
sulfur unit to a capacity of 150 LT/D and construct a 220 LT/D unit, and
construct ancillary facilities to support these units. These plants will have a
combined base capacity of 370 LT/D of sulfur, which can be increased to 510
LT/D of sulfur with oxygen enrichment.

         ADDITIONAL TANK STORAGE CAPACITY. TARC will require additional tankage
to store crude oil and refined products in connection with the refinery's
increased throughput after completion of Phase I. TARC has purchased an
adjacent storage terminal and also plans to construct or lease additional
storage facilities in order to conduct refinery operations at expected levels.
Pressurized tanks with a storage capacity of 127,500 barrels will be
constructed for LPG and butane.

         OFFSITE FACILITIES. TARC will add steam-generating capacity, air
compression equipment and new electrical equipment during Phase I. A marine
vapor recovery system will also be installed at the terminal docks. TARC is
adding equipment necessary to load petroleum coke at the GATX No. 2 dock. TARC
is performing the engineering on these facilities with support from specialty
engineering firms such as River Consulting Inc., Lanier and Associates, ABB
Combustion Engineering Systems and RPM Engineering Inc.

         OTHER. Additional equipment will be installed to enhance waste water
treatment and reduce the generation of solid waste. TARC is required to perform
Hazardous Operation ("HAZOP") analysis of the refinery process units as
required by Occupational Safety and Health Administration ("OSHA") regulations.

PHASE II

         Phase II includes the FCC Unit, FCC Upgrades, Alkylation Unit and some
additional Offsite Facilities. Startup of these facilities will increase the
refinery's output of higher margin finished products, primarily gasoline and
No. 2 fuel oil. TARC anticipates that, following completion of Phase II, it
will have the capacity to process in excess of 200,000 Bpd of combined heavy,
sour crude oil and atmospheric residual oil. The following is a brief
description of the units and offsite facilities that are scheduled to be added
or improved during Phase II and TARC's plans and expectations therefor:

         FLUID CATALYTIC CRACKING (FCC) UNIT. TARC's FCC Unit will process gas
oil feedstocks directly from the No. 2 Crude Unit, the No. 2 Vacuum Unit, the
Delayed Coking Unit, or from outside purchases of VGO or atmospheric residual
oil. Before being fed to the FCC Unit, some of the VGO will be desulfurized in
the HDS Unit in order to meet environmental guidelines and improve product
quality from the FCC Unit. Modernization of the FCC Unit includes
reconfiguration of the fractionation plant.

         The FCC Unit will have an initial capacity of 100,000 Bpd and will
incorporate the state-of-the-art MSCC(SM) technology licensed by UOP, formerly
Universal Oil Products ("UOP"). The MSCC(SM) technology is currently being used
at a major U.S. refinery. TARC believes that this technology will improve
product yields and quality in comparison to conventional catalytic cracking
processes. TARC also plans to add a catalyst cooler, which will make the unit
capable of processing significant quantities of atmospheric residual
feedstocks.





                                       75
<PAGE>   83
         The FCC Unit produces refinery fuel, propane, butane, light olefins,
gasoline blendstock, No. 2 fuel oil, and a residual product (decant/slurry
oil). Light olefins will be processed in the Alkylation Unit for further
upgrade. Other materials will be blended to finished products or consumed in
the refinery.

         Process engineering for the MSCC(SM) technology has been completed by
UOP. Raytheon Engineers and Constructors Inc. ("Raytheon") is providing
detailed design engineering. Most major equipment has been procured and is
being fabricated by a number of major pressure vessel fabricators. Raytheon has
commenced the process engineering of the gas recovery section, and field
inspection and testing of the existing equipment is underway. Raytheon is
providing construction management services for the FCC Unit.

         FCC FLUE GAS SCRUBBER. TARC plans to install a scrubber for the FCC
flue gases to reduce particulate and sulfur dioxide emissions. The flue gas
scrubber has been designed and fabricated by Belco Technologies Inc., and will
be erected under a fixed price contract.

         ALKYLATION UNIT. Light olefins from the FCC Unit are converted to high
octane gasoline blendstock (alkylate) in the Alkylation Unit. Alkylate is a
relatively clean burning fuel component important in the production of
environmentally sensitive gasolines. The Alkylation Unit will be reactivated
and expanded to an ultimate capacity of approximately 26,000 Bpd of alkylate
product by installing four new contactors and two new settlers designed by
Stratco Inc. Remaining work includes inspection and testing of the equipment in
the existing unit and installation of a new electronic instrumentation system.
Raytheon is providing engineering and construction management services for this
work.

         OFFSITE FACILITIES/TANKAGE. Additional capacity will be installed for
cooling water, steam, plant air, instrument air and electrical distribution.
Construction of nine tanks, with aggregate capacity of one million barrels,
will be completed. Other piping, electrical and instrumentation equipment will
be installed to connect the Phase II process units with the refinery and new
storage tanks.

         OTHER. TARC is required to perform HAZOP analysis of the refinery
process units added during Phase II as required by OSHA regulations.

PORT COMMISSION BONDS

         TARC and the Port Commission have entered into a preliminary agreement
for the issuance of revenue bonds, which, if issued, are expected to provide
proceeds to TARC of approximately $50 million. Proceeds of such bonds would be
used to construct tank storage facilities, docks, and air and waste water
treatment facilities included in the Capital Improvement Program budget. The
Port Commission would own the facilities built with the proceeds of the bonds,
and TARC would operate the facilities pursuant to a long-term (25-year) lease.
TARC is currently working with an underwriter to structure an offering of
revenue bonds pursuant to this preliminary agreement. There can be no
assurance, however, that the issuance of any such tax-exempt bonds will occur.

FINANCING ARRANGEMENTS AND PROCESSING AGREEMENTS

         TARC historically has entered into financing arrangements in order to
maintain an available supply of feedstocks. Typically, TARC enters into an
agreement with a third party to acquire a cargo of feedstock which is scheduled
for delivery to TARC's refinery. TARC pays through the third party all
transportation costs, related taxes and duties and letter of credit fees for
the cargo, plus a negotiated commission. Prior to arrival at the refinery,
another third party purchases the cargo, and TARC commits to purchase, at a
later date, the cargo at an agreed price plus commission and costs. TARC also
places margin deposits with the third party to permit the third party to hedge
its price risk. TARC purchases these cargos in quantities sufficient to
maintain expected operations and is obligated to purchase all of the cargos
delivered pursuant to these arrangements. In the event the refinery is not
operating, these cargos may be sold on the spot market.

         In April 1996, TARC entered into a processing agreement with a third
party to process feedstocks. Under the terms of the agreement, the processing
fee earned by TARC is based on the margin, if any, earned by the third party
from product sales, after deducting all of its related costs such as feedstock
acquisition, hedging, transportation, processing and inspections plus a
commission for each barrel processed. As of July 31, 1997, TARC has processed
6.4 million barrels of feedstocks under this agreement. As of July 31, 1997 and
January 31, 1997, TARC was storing approximately 0.8 million and 1.0 million
barrels, respectively, of feedstock and intermediate or refined products. For
the six months ended July 31, 1997 and 1996, TARC recorded income (loss) from
processing agreements of $3.2 million and $(3.3) million, respectively.
Included in the 0.8 million barrels of product stored at the refinery as of
July 31, 1997, is approximately 0.6 million barrels of feedstock related to a
purchase commitment entered into in April 1997. The 0.6 million barrels have
been sold to the third party involved in the processing arrangement. For the
six months ended July 31, 1997, TARC incurred a loss of approximately $4.8
million related to this purchase commitment.

         TARC also entered into processing agreements with this third party to
process approximately 1.1 million barrels of the third party's feedstocks for a
fixed price per barrel. As of July 31, 1997, TARC recorded a net margin of
approximately $0.2 million related to these processing arrangements, primarily
as a result of income on the fixed fee processing agreement.

PRICE MANAGEMENT ACTIVITIES

         In order to mitigate the commodity price risks associated with the
refining business, TARC has previously entered, and may in the future enter,
into futures contracts, options on futures, swap agreements and forward sale
agreements commensurate with its inventory levels and feedstock requirements
and as permitted under the Indenture. If TARC believes it can capitalize on
favorable market conditions, it will attempt to utilize the futures market to
fix a portion of its crude oil costs and refined products values. This hedging
strategy is designed to retain the value of a portion of its work-in-process
inventory.





                                       78
<PAGE>   86
CRUDE OIL AND FEEDSTOCK SUPPLY

         TARC purchases feedstocks on the spot market but has no long-term
supply contracts. TARC believes that it will have access to adequate supplies
of the crude oil it intends to process. Upon completion of the Capital
Improvement Program, TARC expects to purchase heavy, sour crude oil produced in
countries such as Venezuela and Mexico. In addition, TARC expects to be able to
take advantage of anticipated increases in production of sour crude oil from
the Gulf of Mexico or the Persian Gulf.

         The refinery has a variety of supply channels. The Mississippi River
permits delivery of feedstocks from both barge and ocean-going vessels. With
the purchase of the adjacent terminal, TARC has four ship docks and a barge
dock. TARC's title to and continued use of these facilities is subject to the
rights of the government and public use. TARC's ship dock can accommodate
100,000 deadweight ton ("dwt") tankers that draw less than 45 feet of water, or
up to 200,000 dwt tankers that have been partially offloaded and draw less than
45 feet of water. The barge dock provides access to smaller cargos of
intermediate feedstocks such as VGOs or atmospheric residuals. Additionally,
TARC is connected to a Shell Oil Company ("Shell") crude pipeline that provides
access to Louisiana Offshore Oil Port's 24-inch pipeline network, thereby
permitting TARC to receive large quantities of foreign crude oil. This pipeline
also provides access to Louisiana and other domestic crudes. See "-- Title
Insurance."

         TARC has no crude oil reserves and is not engaged in the exploration
for crude oil and plans to obtain all its crude oil requirements from
unaffiliated sources. TARC believes that it will be able to obtain adequate
supplies of crude oil and feedstocks at generally competitive prices for the
foreseeable future. Crude oil prices are affected by a variety of factors that
are beyond the control of TARC. The principal factors currently influencing
prices include the pricing and production policies of members of the
Organization of Petroleum Exporting Countries, the availability to world
markets of production from Kuwait, Iraq and Russia and the worldwide and
domestic demand for oil and refined products. Oil pricing will continue to be
unpredictable and greatly influenced by governmental and political forces.

PRODUCT DISTRIBUTION

         TARC previously sold its refined products pursuant to a processing
agreement with a third party, but currently has no long-term sales contracts.
Major market areas for TARC's refined products will include the Gulf Coast
region, the Mississippi River Valley and the East Coast of the United States,
as well as foreign markets. TARC's refined products will be transported by
pipeline, rail tanker, ocean-going vessel and tank truck. TARC's refinery is
connected, through third-party pipelines, to two major Gulf Coast common
carrier pipelines, the Colonial and the Plantation, which will permit
transportation of the refinery's products to East Coast markets. Products can
be discharged into these pipelines at rates of up to 15,000 Bbls per hour. TARC
is also connected to several pipelines designed to transfer refined products to
a nearby refinery operated by Shell. Railroad lines serve the refinery and
adjacent industries. TARC's barge and ship docks provide access to the
Mississippi River and the intracoastal waterway.

FOREIGN TRADE ZONE

         The refinery is approved for purposes of processing foreign crude to
operate as a foreign trade zone. This allows the refinery to realize the
benefits of processing foreign crude and exporting the products duty free or
deferring the duty on products sold domestically.

INSURANCE

         TARC maintains insurance in accordance with customary industry
practices to cover some, but not all, risks. TARC currently maintains property
insurance for the refinery in an amount and with deductibles that management
believes will allow TARC to survive damage to the refinery. TARC plans to
increase insurance coverage amounts from time to time as it completes certain
portions of the Capital Improvement Program.





                                       79
<PAGE>   87
SEASONALITY

         TARC anticipates that its operations will be subject to significant
fluctuations in seasonal demand. In TARC's markets, demand for gasoline is
typically higher during the first and second quarters of TARC's fiscal year.
During winter months, demand for heating oil increases. The refinery is
designed, upon completion of the Capital Improvement Program, to change its
product yields to take advantage of seasonal demands.

FLUCTUATION IN PRICES

         Factors that are beyond the control of TARC may cause the cost of
crude oil purchased by TARC and the price of refined products sold by TARC to
fluctuate widely. Although prices of crude oil and refined petroleum products
generally move in the same direction, prices of refined products often do not
respond immediately to changes in crude oil costs. An increase in market prices
for crude oil or a decrease in market prices for refined products could have an
adverse impact on TARC's earnings and cash flow.

COMPETITION

         The industry in which TARC operates is highly competitive. Since the
United States imports significant quantities of refined petroleum products,
TARC views offshore refiners as its primary competition. However, TARC also
competes with refiners in the Gulf Coast region, many of which are owned by
large, integrated oil companies that because of their more diverse operations,
stronger capitalizations or crude oil supply arrangements, are better able than
TARC to withstand volatile industry conditions, including shortages or excesses
of crude oil or refined products or intense price competition. The principal
competitive factors affecting TARC's refining operations are the quality,
quantity and delivered costs of crude oil and other refinery feedstocks,
refinery processing efficiency, mix of refined products, refined product prices
and the cost of delivering refined products to markets. Competition also exists
between the petroleum refining industry and other industries supplying energy
and fuel to industrial, commercial and individual consumers.

EMPLOYEES

         As of September 30, 1997, TARC had approximately 270 employees and
will employ additional personnel as required by its operations and may engage
the services of engineering and other consultants from time to time. Currently,
none of TARC's employees is a party to a collective bargaining agreement. The
Equal Employment Opportunity Commission (the "EEOC") has initiated an
investigation into the employment practices of TARC and Southeast Louisiana
Contractors of Norco, Inc. ("Southeast Contractors"), a subsidiary of
TransAmerican, alleging discriminatory hiring and promotion practices. See "--
Legal Proceedings."

         Since July 1994, Southeast Contractors has provided construction
personnel to TARC in connection with construction at the refinery. Southeast
Contractors will provide construction personnel to TARC as required to
implement the Capital Improvement Program. These construction workers are
temporary employees, and the number and composition of the workforce will vary
throughout the reactivation of the refinery during the Capital Improvement
Program. Southeast Contractors charges TARC for the direct costs it incurs,
which consist solely of employee payroll and benefits plus administrative costs
and fees; such administrative costs and fees charged to TARC may be up to $2
million per year.

ENVIRONMENTAL MATTERS

         COMPLIANCE MATTERS. TARC is subject to federal, state and local laws,
regulations and ordinances ("Pollution Control Laws"), which regulate
activities such as discharges to air and water, as well as handling and
disposal practices for solid and hazardous wastes. TARC believes that it is
now, and has included in the Capital Improvement Program sufficient capital
additions to remain, in substantial compliance with applicable Pollution
Control Laws. However, Pollution Control Laws that may be enacted in the
future, as well as increasingly strict enforcement of existing Pollution





                                       80
<PAGE>   88
Control Laws, may require TARC to make additional capital expenditures in order
to comply with such laws and regulations. To ensure continuing compliance, TARC
has made environmental compliance and permitting issues an integral part of its
refinery's start-up plans and has budgeted for such capital expenditures in the
Capital Improvement Program. However, there is no assurance that TARC will
remain in compliance with environmental regulations.

         TARC uses (and in the past has used) certain materials, and generates
(and in the past has generated) certain substances or wastes, that are or may
be deemed hazardous substances or wastes. In the past, the refinery has been
the subject of certain environmental enforcement actions, and has incurred
certain fines, as a result of certain of TARC's operations. TARC also was
previously subject to enforcement proceedings relating to its prior production
of leaded gasoline and air emissions. TARC believes that, with minor exception,
all of these past matters were resolved prior to or in connection with the
resolution of the bankruptcy proceedings of its predecessor in interest,
TransAmerican, or are no longer applicable to TARC's operations. As a result,
TARC believes that such matters will not have a material adverse effect on
TARC's future results of operations, cash flow or financial position.

         REQUIREMENTS UNDER THE FEDERAL CLEAN AIR ACT. The National Emission
Standards for Hazardous Air Pollutants for Benzene Waste Operations (the
"Benzene Waste NESHAPS"), promulgated in January 1993 pursuant to the Clean Air
Act, regulate benzene emissions from numerous industries, including petroleum
refineries. The Benzene Waste NESHAPS require all existing, new, modified, or
reconstructed sources to reduce benzene emissions to a level that will provide
an ample margin of safety to protect public health. TARC will be required to
comply with the Benzene Waste NESHAPS as its refinery operations start up. TARC
believes that compliance with the Benzene Waste NESHAPS will not have a
material adverse effect on TARC's financial position, results of operations or
cash flows. Until the refinery is in full operation, however, there can be no
assurance that the regulations will not have such an effect.

         In addition, the EPA promulgated National Emission Standards for
Hazardous Air Pollutants for Hazardous Organics (the "Hazardous Organic
NESHAPS") regulations for petroleum refineries under the Clean Air Act in 1995,
and subsequently has amended such regulations. These regulations set "Maximum
Achievable Control Technology" ("MACT") standards for petroleum refineries. The
Louisiana Department of Environmental Quality (the "LDEQ") has incorporated
MACT standards into TARC's air permits under federal and state air pollution
prevention laws. TARC believes that compliance with the Hazardous Organics
NESHAPS will not have a material adverse effect on TARC's financial position,
results of operations or cash flow. Until the refinery is in full operation,
however, there can be no assurance that the regulations will not have such an
effect.

         The EPA promulgated federal regulations pursuant to the Clean Air Act
to control fuels and fuel additives (the "Gasoline Standards") that could have
a material adverse effect on TARC. Under these regulations, only reformulated
gasoline can be sold in certain domestic geographic areas in which the EPA has
mandated or approved its use. Reformulated gasoline must contain a minimum
amount of oxygen, have a lower vapor pressure, and have reduced sulfur,
olefins, benzene and aromatics compared to the average 1990 gasoline. The EPA
recently promulgated final National Ambient Air Quality Standards ("NAAQS")
that revise the standards for particulate matter and ozone. The number and
extent of the areas subject to reformulated gasoline standards may increase in
the future after the NAAQS are implemented. Conventional gasoline may be used
in all other domestic markets; however, a refiner's post-1994 average
conventional gasoline must not be more polluting than it was in 1990. With
limited exceptions, to determine its compliance as of January 1, 1995, a
refiner must compare its post-1994 and 1990 average values of controlled fuel
parameters and emissions. The Gasoline Standards recognize that many gasoline
refiners may not be able to develop an individual 1990 baseline for a number of
reasons, including, for example, lack of adequate data or the absence or
limited scope of operations in 1990. Under such circumstances, the refiner must
use a statutory baseline reflecting the 1990 industry average. The EPA has
authority, upon a showing of extenuating circumstances by a refiner, to grant
an individual adjusted baseline or other appropriate regulatory relief to that
refiner.

         TARC filed a petition with the EPA requesting an individual baseline
adjustment or other appropriate regulatory relief based on extenuating
circumstances. The extenuating circumstances upon which TARC relied in its
petition include the fact that the refinery was not in operation in 1990 (and
thus there is no 1990 average for purposes of the necessary comparison) and the
fact that the start-up of the refinery is to occur on a phased-in basis. The
EPA has





                                       81
<PAGE>   89
denied TARC's request for an individual baseline adjustment and other
regulatory relief. TARC will continue to pursue regulatory relief with the EPA.
However, the projections included herein assume that regulatory relief will not
be granted. There can be no assurance that any action taken by the EPA will not
have a material adverse effect on TARC's future results of operations, cash
flows or financial position.

         Title V of the Clean Air Act requires states to implement an Operating
Permit Program that codifies all federally enforceable limitations that are
applicable to a particular source. The EPA has approved Louisiana's Title V
Operating Permit Program. The deadline for a refinery to submit an Operating
Permit Application under the Louisiana program was October 12, 1996. TARC
timely submitted its Title V Operating Permit application and the LDEQ has
designated the application as being administratively complete. As yet, the LDEQ
has not responded further regarding the status of TARC's Title V Operating
Permit. TARC believes that its application will be approved. However, there can
be no assurance that it will be approved as submitted or that additional
expenditures required pursuant to Title V Operating Permit obligations will not
have a material adverse effect on TARC's financial position, results of
operations or cash flow.

         CLEANUP MATTERS. TARC also is subject to federal, state and local
laws, regulations and ordinances that impose liability for the costs of clean
up related to, and certain damages resulting from, past spills, disposals or
other releases of hazardous substances ("Hazardous Substance Cleanup Laws").
Over the past several years, TARC has been, and to a limited extent continues
to be, engaged in environmental cleanup or remedial work relating to or arising
out of operations or activities at the refinery. In addition, TARC has been
engaged in upgrading its solid waste facilities, including the closure of
several waste management units. Similar to numerous other industrial sites in
the state, the refinery has been listed by the LDEQ on the Federal
Comprehensive Environmental Response, Compensation and Liability Information
System, as a result of TARC's prior waste management activities (as discussed
below).

         In 1991, the EPA performed a facility assessment at the refinery
pursuant to the Federal Resource Conservation and Recovery Act ("RCRA"). The
EPA performed a follow up assessment in March 1996, but has not yet issued a
report of its investigations. In July 1996, the EPA and the LDEQ agreed that
the LDEQ would serve as the lead agency with respect to the investigation and
remediation of areas of concern identified in the investigations. TARC, under a
voluntary initiative approved by the LDEQ, has submitted a work plan to the
LDEQ to determine which areas may require further investigation and
remediation. The LDEQ has not yet responded to TARC's submission or issued any
further requests relating to this matter. As a result, TARC is unable at this
time to estimate what the costs, if any, will be if the LDEQ does require
further investigation or remediation of the areas identified.

         TARC has been identified as a potentially responsible party ("PRP")
under the Comprehensive Environmental Response, Compensation, and Liability Act
of 1980, as amended ("CERCLA" or "Superfund"), for the cleanup of contamination
from hazardous substances at three Superfund sites (i.e. sites on the National
Priorities List ("NPL")) to which it has been alleged that TARC, or its
predecessors, sent hazardous substances in the past. CERCLA requires cleanup of
sites from which there has been a "release" or threatened release of "hazardous
substances" (as such terms are defined under CERCLA). CERCLA requires the EPA
to include sites needing long-term study and cleanup on the NPL based on their
potential effect on public health or the environment. CERCLA authorizes the EPA
to take any necessary response actions at NPL sites and, in certain
circumstances, to order PRPs liable for the release to take such actions. PRPs
are broadly defined under CERCLA to include past and present owners and
operators of a site, as well as generators and transporters of wastes to a site
from which hazardous substances are released.

         The EPA may seek reimbursement of expenditures of federal funds from
PRPs under Superfund. Courts have interpreted CERCLA to impose strict, joint
and several liability upon all persons liable for the entire amount of
necessary cleanup costs. As a practical matter, at sites where there are
multiple PRPs for a cleanup, the costs of cleanup typically are allocated
according to a volumetric or other standard among the parties. CERCLA also
provides that responsible parties generally may recover a portion of the costs
of cleaning up a site from other responsible parties. Thus, if one party is
required to clean up an entire site, that party can seek contribution or
recovery of such costs from other responsible parties. A number of states have
laws similar to Superfund, pursuant to which cleanup obligations, or the costs
thereof, also may be imposed.





                                       82
<PAGE>   90
         At one Superfund site, TARC has submitted information to the EPA
indicating that it should have no liability for this matter, and negotiations
with the EPA in this regard are continuing. With respect to the remaining two
sites, TARC's liability for each such matter has not been determined, and TARC
anticipates that it may incur costs related to the cleanup (and possibly
including additional costs arising in connection with any recovery or other
actions brought pursuant or relating to such matters) at each such site. After
a review of the data available to TARC regarding the basis of TARC's alleged
liability at each site, and based on various factors, which depend on the
circumstances of the particular Superfund site (including, for example, the
relationship of TARC to each such site, the volume of wastes TARC is alleged to
have contributed to each such site in comparison to other PRPs without giving
effect to the ability of any other PRPs to contribute to or pay for any
liabilities incurred, and the range of likely cleanup costs at each such site)
TARC does not believe its ultimate environmental liabilities will be
significant; however, it is not possible to determine the ultimate
environmental liabilities, if any, that may arise from the matters discussed
above.

OTHER GOVERNMENTAL REGULATIONS

         TARC must also comply with federal and state laws and regulations
promulgated by the Department of Transportation for the movement of volatile
and flammable materials, the U.S. Coast Guard for marine operations and oil
spill prevention and OSHA for worker and job site safety. To comply with OSHA
regulations, TARC must conduct extensive Process Safety Management and
Hazardous Operations reviews prior to placing units into service. TARC has
budgeted funds in the Capital Improvement Program to comply with all of these
requirements.

PROPERTIES

         With the purchase of the adjacent terminal facility, TARC owns the
approximately 457-acre site on which the refinery and terminal are located.
TARC also owns approximately 500 acres of wetlands adjacent to the refinery
site. TARC leases office space in Houston, Texas from TransTexas.

TITLE INSURANCE

         TARC has obtained a lender's title insurance policy in the amount of
approximately $840 million for the benefit of the Trustee to insure against
certain claims made against title to the refinery parcel site. The title
insurance policy is expected to be reinsured through various title insurance
companies in the United States. The ability to successfully recover under the
policy is dependent on the creditworthiness of the title company and its
reinsurers at the time of the claim and any defenses that the title insurers
and its reinsurers may have. The title insurance policy will not insure TARC or
the Trustee for defects, liens, encumbrances, adverse claims or other matters
known to TARC that affect the validity of the mortgage or title to the
refinery. There can be no assurance that the amount of title insurance will be
sufficient to cover any losses incurred by TARC or the Trustee as a result of a
title defect impairing the ability to use the refinery site or that the title
insurers will be able to fulfill their financial obligations under the title
insurance policy. The title insurance policy contains customary exceptions to
coverage, including taxes not yet due and payable, riparian rights and numerous
servitudes, rights of way, rights of access and other encroachments in favor of
utilities, railroads, pipelines and adjacent refineries and tank farms, as well
as exceptions for (i) government claims with respect to, and public rights to
use, TARC's property located between the Mississippi River and the road upon
which pipe racks and TARC's docking facilities are located, (ii) a right of
first refusal in favor of an adjacent landowner with respect to a certain
portion of property which, in the event exercised, may require TARC to relocate
at its expense certain pipelines that connect various refinery parcels, (iii)
tax benefits that have been conveyed to certain tax lessors, (iv) the priority
of liens that may be filed by materialmen and mechanics in connection with the
Capital Improvement Program and (v) any rights of creditors pursuant to federal
or state bankruptcy and insolvency laws, which rights may affect the
enforceability of the mortgage securing the TARC Intercompany Loan.

LEGAL PROCEEDINGS

         EEOC. On August 31, 1995, the U.S. Equal Employment Opportunity
Commission ("EEOC") issued a Commissioner's Charge against TARC and Southeast
Louisiana Contractors of Norco, Inc. (the "Commissioners Charge") pursuant to
Sections 706 and 707 of Title VII of the Civil Rights Act of 1964, as amended,
42 U.S.C. Section 2000e et seq. ("Title VII"). In the Commissioner's Charge,
the EEOC charged TARC and Southeast Louisiana Contractors of Norco, Inc.
("Southeast Contractors"), a subsidiary of TransAmerican, with engaging in
unlawful discriminatory hiring and promotion practices based on race and
gender. Each violation of Title VII, if proven, potentially could subject TARC
and/or Southeast Contractors to liability for (i) monetary damages for backpay
and/or front pay in an undetermined amount, and for compensatory damages and/or
punitive damages in an amount that should not exceed $300,000, (ii) injunctive
relief, (iii) attorney's fees, and/or (iv) interest. During the period covered
by the Commissioner's Charge, TARC and Southeast Contractors estimate that they
received a combined total of approximately 15,000 to 22,000 employment
applications and hired (or rehired) a combined total of approximately 1,500 to
2,200 workers. TARC and Southeast Contractors have responded to the
Commissioner's Charge and have denied engaging in any unlawful employment
practices. TARC and Southeast Contractors have been cooperating fully with the
EEOC in connection with its investigation. TARC and Southeast Contractors
intend to vigorously defend against the allegations contained in the
Commissioner's Charge in all proceedings before the EEOC and in any subsequent
litigation. If TARC and/or Southeast Contractors are found liable for
violations of Title VII based on the matters asserted in the Commissioner's
Charge, TARC can make no assurance that such liability would not have a
material adverse effect on the financial condition, results of operations and
cash flows of TARC or TARC's ability to pay interest or principal on its debt.

         RINEHEART. On October 8, 1996, Carlton Gene Rineheart, et al., and as
representative of a class of persons similarly situated, filed suit against 84
individuals and corporations, including TARC, in the U.S. District Court,
Middle District of Louisiana alleging negligent and improper storage, handling,
treatment, and disposal of hazardous materials from 1976 to the present at two
sites in Iberville Parish, Louisiana. The suit claims damages for physical,
mental, and property damage in the communities of Bayou Sorrel, Bayou Pigeon
and Indian Village. TARC intends to vigorously defend this claim.

         SHELL OIL. On September 27, 1996, Shell Oil filed a third party suit
against TARC in the U.S. District Court, Eastern District of Louisiana for
contribution and/or indemnity relating to alleged environmental contamination
of Bayou Trapagnier and surrounding lands near Norco, Louisiana. In March 1997,
TARC obtained a voluntary dismissal from Shell. Shell proceeded to trial on the
main case and settled with the plaintiffs during trial by purchasing their land
for $5 million. On June 27, 1997, Shell amended its third party action to bring
TARC back into the case. Shell has demanded $400,000 from TARC. TARC has
refused to pay such amount and is defending the case vigorously.

         GENERAL. TARC is also a named defendant in other ordinary course,
routine litigation incidental to its business. While the outcome of these other
lawsuits cannot be predicted with certainty, TARC does not expect these matters
to have a material adverse effect on its financial position, results of
operations or cash flow.

SAVINGS PLAN

      The Company maintains a long-term savings plan (the "Savings Plan") in
which eligible employees of the Company and certain of its affiliates may elect
to participate. Each employee becomes eligible to participate in the Savings
Plan on January 1 or July 1 following the completion of one year of service
with the Company or its participating affiliates and attainment of age 21. The
Savings Plan is intended to constitute a qualified plan under Section 401(a) of
the Internal Revenue Code of 1986, as amended (the "Code") and contains a
salary reduction arrangement described in Section 401(k) of the Code.

      Each participant may elect to reduce his compensation by a percentage
equal to 2% to 15% and the Company will contribute that amount to the Savings
Plan on a pre-tax basis on behalf of the participant. The Code limits the
annual amount that a participant may elect to have contributed on his behalf on
a pre-tax basis to the Savings Plan. For 1997, this limit is $9,500. The
Company presently makes a matching contribution in an amount equal to 10%, 20%,
or 50% of the amount elected to be contributed by each participant on a pre-tax
basis, up to a maximum of 3% of each participant's compensation, depending on
whether the employee has been a participant in the Savings Plan for one year,
two years, or three years. Each participant also may elect to contribute up to
10% of his compensation to the Savings Plan on an after-tax basis. The Code
imposes nondiscrimination tests on contributions made to the Savings Plan
pursuant to participant elections and on the Company's matching contributions,
and limits amounts which may be allocated to a participant's Savings Plan
account each year. In order to satisfy the nondiscrimination tests,
contributions made on behalf of certain highly compensated employees (as
defined in the Code) may be limited. Contributions made to the Savings Plan
pursuant to participant elections and matching contributions are at all times
100% vested. Contributions to the Savings Plan are invested, according to
specified investment options selected by the participants, in investment funds
maintained by the trustee of the Savings Plan. Generally, a participant's
vested benefits will be distributed from the Savings Plan as soon as
administratively practicable following a participant's retirement, death,
disability, or other termination of employment. In addition, a participant may
elect to withdraw his after-tax contributions from the Savings Plan prior to
his termination of employment, and subject to strict limitations and
exceptions, the Savings Plan provides for withdrawals of a participant's
pre-tax contributions prior to a participant's termination of employment, in
the event of the participant's severe financial hardship or attainment of age
59 1/2. The Savings Plan may be amended or terminated by the Board of Directors
of the Company. As of September 30, 1997, approximately 1,590 employees were
eligible to participate in the Savings Plan, including Messrs.
Stanley, Brackenridge, Donahue, Bianchi and McGinnis.

DIRECTOR COMPENSATION

      Each director of the Company is paid an annual director's fee of $75,000
plus $750 for each board meeting and committee meeting attended (excluding
committee meetings occurring on the same day as board meetings).

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

      The Company does not directly compensate any of its executive officers.
The Company does not have a Compensation Committee. During the fiscal year
ended January 31, 1997, none of the members of the compensation committees of
TransTexas or TARC was an officer or employee of the Company or any of its
subsidiaries, and none had any relationship with the Company requiring
disclosure under Item 404 of Regulation S-K. See "Certain Relationships and
Related Transactions."

                             SECURITY OWNERSHIP OF
                    CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

      The Company's common stock is owned 100% by TransAmerican. TransAmerican
is owned 100% by TNGC, and TNGC is owned 100% by John R. Stanley. No other
officer or director of the Company owns any common stock of the Company. As of
July 31, 1997, there were 9,000 shares of common stock outstanding and no
shares of preferred stock outstanding.


                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

      Pursuant to the asset transfer agreement (the "Asset Transfer Agreement")
among TransAmerican, TransTexas, TTC and Mr. Stanley, TransAmerican assigned
and transferred to TransTexas (the "Asset Transfer") all operating assets
relating to its natural gas exploration, production and transportation
business, subject to the existing liens on those assets, other than (i) certain
mineral interests that were subject to restriction on transfer pursuant to the
terms of the instruments evidencing those interests, (ii) capital stock of any
of its subsidiaries and (iii) cash and accounts receivable in the amount of $37
million.

      TransTexas assumed substantially all liabilities relating to
TransAmerican's natural gas exploration, production and transportation
business. On June 13, 1997, the Asset Transfer Agreement was amended to
eliminate any indemnity obligations of TransAmerican to TransTexas with respect
to such liabilities.

      TransTexas has provided accounting and legal services to TARC and TEC and
drilling and workover, administrative and procurement, accounting, legal, lease
operating, and gas marketing services to TransAmerican pursuant to a services
agreement. TransTexas has provided general commercial legal services and
certain accounting services (including payroll, tax, and treasury services) to
TARC and TEC for a fee of $26,000 per month. TARC expects its general and
administrative expenses to increase significantly when the refinery commences
more complex operations. At TransAmerican's request, TransTexas, at its
election, has provided drilling and workover services. In June 1997, the
receivable from TransAmerican under the services agreement was paid and the
services agreement was terminated.

      On June 13, 1997, a new services agreement was entered into among
TransAmerican, TEC, TARC and TransTexas. Under the new services agreement,
TransTexas will provide accounting, legal, administrative and other services to
TARC, TEC and TransAmerican and its affiliates. TransAmerican will provide
advisory services to TransTexas, TARC and TEC. TARC will pay to TransTexas
approximately $300,000 per month for services rendered to, and for allocated
expenses paid by TransTexas on behalf of, TARC and TEC. TEC and its
subsidiaries will pay $2.5 million in the aggregate per year to TransAmerican
for advisory services and benefits provided by TransAmerican.

      In December 1994, TransTexas entered into an interruptible gas sales
agreement with TransAmerican, revenues from which totaled approximately $14.8
million, $11.1 million, $11.7 million, and $11.7 million for the year ended
July 31, 1995, the six months ended January 31, 1996, the year ended July 31,
1997 and the six months ended July 31, 1996 and 1997, respectively.
TransAmerican did not purchase any gas from TransTexas for the six months ended
July 31, 1997. All amounts owed under the agreement were paid on June 13, 1997.

      In July 1995, TransTexas acquired certain oil leases in the Lodgepole
Prospect in North Dakota from TransAmerican for approximately $6.3 million,
which amount represented TransAmerican's cost for such leases. TransTexas
continued to acquire additional leases in the area. In October 1995, TransTexas
sold an undivided interest in its Lodgepole leases to TransDakota Oil
Corporation ("TDOC"), a subsidiary of TransAmerican. The sales price was
approximately $16.1, which amount represented the cost to TransTexas of the
interest sold. In September 1996, TransTexas purchased these and other oil and
gas leasehold interests in the Lodgepole area from TDOC for approximately $20.0
million. TransTexas believes that the combination of these interests, together
with TransTexas'





                                       89
<PAGE>   97
other interests in the Lodgepole area, will produce a more marketable property
package. The purchase price was $3.9 million greater than TDOC's basis in the
properties.

      In September 1995, TransTexas made advances to TransAmerican in the
aggregate amount of $4.7 million. In October 1995, TransAmerican repaid the
full amount of these advances with interest at an annualized rate of 13%.

      In October 1995, Mr. Stanley guaranteed TransTexas' $40 million line of
credit with BNY Financial Corporation.

      As of January 1996, TransTexas and TransTexas Exploration Corporation, a
wholly owned subsidiary of TransTexas ("TTEX"), entered into a Drilling
Program, as defined in the TransTexas Senior Secured Notes Indenture. Pursuant
to the Drilling Program, TTEX received a portion of revenues, in the form of a
production payment, from certain of TransTexas' wells. The production payment
was transferred in consideration of a note payable in the amount of $23.7
million issued by TTEX. In July 1996, TTEX transferred this production payment
to TransTexas in the form of a dividend, and TransTexas forgave the $13.2
million remaining balance of the note payable.

      Since July 1996, TTEX has made advances to TransAmerican pursuant to the
terms of a $25 million promissory note due July 31, 1998 that bears interest,
payable quarterly, at 15% per annum. This note was repaid on June 13, 1997.

      During 1995, TransAmerican acquired an office building which it
subsequently sold to TransTexas in February 1996 for $4 million. In February
1996, TransAmerican advanced $4 million of the proceeds from this sale to TARC
for working capital.

      In order to facilitate the settlement of certain litigation in May 1996,
TransTexas advanced to TransAmerican $16.4 million of the settlement amount in
exchange for a note receivable. All amounts outstanding under this note were
repaid on June 13, 1997.

      In September 1996, TransTexas and TransAmerican entered into an agreement
pursuant to which TransTexas obtained an $11.5 million dollar-denominated
production payment, subsequently increased to $19 million, bearing interest at
17% per annum, burdening certain oil and gas interests owned by TransAmerican
as a source of repayment for certain of the receivables from TransAmerican
discussed above. At January 31, 1997, $59 million of remaining related-party
receivables has been recorded as a contra-stockholder equity account due to
uncertainties regarding the repayment terms for such receivables. TransTexas
has agreed to defer any interest payments due from TransAmerican until 1998. On
January 31, 1997, TransAmerican conveyed at historical cost certain oil and gas
properties to TransTexas for a purchase price of $31.6 million. A portion of
the purchase price was used to offset obligations under the September 1996
production payment.

      TransTexas has made various advances to TransAmerican in an aggregate
amount of approximately $7 million for lease purchases and other corporate
expenses. This amount was repaid on June 13, 1997.

      In January 1997, an affiliate of TransTexas contributed all of the
outstanding common stock of Signal Capital Holdings Corporation ("SCHC"), with
a book value of $6 million, to TransTexas. In the same month, TransTexas
contributed the stock of SCHC to TTC. Also in January 1997, TransTexas
contributed substantially all of its Lobo Trend properties to TTC.

      Certain refinery assets held by TransAmerican or its subsidiaries,
including the real property on which TARC's refinery is located, were
transferred to TARC in fiscal 1994 at TransAmerican's net book value of
approximately $25 million.

      In July 1994, JRS Ventures, Inc. ("JRS"), owned by John R. Stanley,
conveyed to TARC a portion of the real property on which TARC's refinery is
located. TARC paid JRS $25,000 in October 1997, which is the amount for which
JRS purchased the land in August 1993 from Lynn (as defined).

      A former affiliate of TransAmerican owed $205,000 to Lynn Petroleum
Storage and Transport Co., Inc. ("Lynn"), a company owned by Mr. Stanley's
children. This liability was assumed by TARC in conjunction with the transfer
of refinery assets described above. In May 1995, TARC paid this obligation and
an obligation arising from the purchase





                                       90
<PAGE>   98
of a cryogenic gas processing unit and butane tanks from Lynn at Lynn's
undepreciated book value of such assets of $492,200. TARC believes that the
purchase price for the cryogenic gas processing unit is fair and reasonable to
TARC and on terms no less favorable than could be obtained from an unrelated
third party.

      Pursuant to the stock transfer agreement (the "Stock Transfer Agreement")
among TransAmerican, the Company and TARC, TransAmerican contributed to the
capital of the Company (the "Stock Transfer") (i) all of the outstanding
capital stock of TARC, and (ii) 55 million shares of common stock of
TransTexas; and the Company then contributed 15 million of these shares of
TransTexas common stock to TARC.

      Prior to the sale of the TARC Notes, TARC participated in TransAmerican's
centralized cash management program. Funds required by TARC for daily
operations and capital expenditures were advanced by TransAmerican. In October
1994, TransAmerican sold 5.25 million shares of TransAmerican common stock.
TransAmerican advanced approximately $50 million of the proceeds from these
stock sales to TARC, of which approximately $20 million was used by TARC to
repay a portion of the intercompany debt owed to TransAmerican, and the
remaining $30 million of the net proceeds was used for working capital and
general corporate purposes. TARC used approximately $30 million of the net
proceeds of the sale of the TARC Notes to repay additional intercompany debt to
TransAmerican. TransAmerican contributed to the capital of TARC (through TEC)
all but $10 million of the remainder of TARC's intercompany debt owed to
TransAmerican. In April 1995, TARC repaid the remaining $10 million of
intercompany indebtedness owed to TransAmerican. In August 1995, TARC received
an advance of $3 million from TransTexas which TARC used to settle its
remaining portion of certain litigation. In September 1995, TARC received an
advance of $1.7 million from TransAmerican which TARC used to purchase
feedstock. In October 1995, TARC repaid these advances without interest.
Additionally in October 1995, TARC received an advance of approximately $4
million from TransAmerican for working capital which it repaid in June 1997.

      Southeast Contractors provides construction personnel to TARC in
connection with TARC's expansion and construction program. These construction
workers are temporary employees, and the number and composition of the
workforce will vary throughout TARC's expansion and construction program.
Southeast Contractors charges TARC for the direct costs it incurs (which
consist solely of employee payroll and benefits) plus administrative costs and
fees of up to $2.2 million per year. Total labor costs charged by Southeast
Contractors for the six months ended July 31, 1997 and 1996 were $9.7 million
and $4.4 million, respectively, of which $2.4 million and $1.8 million was
payable at July 31, 1997, respectively.

      TransTexas sells natural gas to TARC under an interruptible long-term
sales contract. Revenues from TARC under this contract totaled approximately
$0.3 million and $1.5 million for the six months ended July 31, 1997 and 1996,
respectively. The receivable from TARC for natural gas sales totaled
approximately $3.0 million at July 31, 1997.

      In September 1995, TARC received an advance of $1 million from TransTexas
which TARC used to purchase feedstock. This advance was repaid by TARC without
interest. In December 1995, TARC advanced $1 million to TransTexas. This
advance was repaid to TARC with interest in December 1995.

      In July 1996, TARC executed a promissory note to TransAmerican for up to
$25 million. The note bore interest at a rate of 15% per annum, payable
quarterly beginning October 31, 1996. On November 1, 1996, TARC executed an
additional $25 million promissory note to TransAmerican which bore interest at
15% per annum, payable quarterly beginning December 31, 1996 (together with the
first promissory note, the "TransAmerican Notes"). In February 1997, the
November 1996 promissory note was replaced with a $50 million note bearing
interest at an annual rate of 15%. TransAmerican waived any default occurring
as a result of TARC's failure to make the scheduled interest payment provided
for in the notes. All amounts outstanding under the TransAmerican Notes were
repaid on June 13, 1997.

     In July 1997, TEC advanced $5 million to TARC. TEC advanced an additional
$41 million in September 1997. All of the advances will be governed by the
terms of a promissory note due June 14, 2002 bearing interest at a rate that,
when added to the interest paid by TransTexas on the TransTexas Intercompany
Loan, will equal the amount of interest payable on the Notes.

     TransAmerican, its existing subsidiaries, including TARC, TEC and
TransTexas, entered into a tax allocation agreement (the "Tax Allocation
Agreement"), the general terms of which require TransAmerican and all of its
subsidiaries to file federal income tax returns as members of a consolidated
group to the extent permitted by law. Filing on a consolidated basis allows
income and tax of one member to be offset by losses and credits of another and
allows deferral of certain intercompany gains; however, each member is
severally liable for the consolidated federal income tax liability of the
consolidated group.

     The Tax Allocation Agreement requires each of TransAmerican's subsidiaries
to pay to TransAmerican each year its allocable share of the federal income tax
liabilities of the consolidated group ("Allocable Share"). The Tax Allocation
Agreement provides for a reallocation of the group's consolidated federal
income tax liabilities among the members if the IRS or the courts ultimately
re-determine the group's regular tax or alternative minimum tax liability. In
the event of an IRS audit or examination, the Tax Allocation Agreement
generally gives TransAmerican the authority to compromise or settle disputes
and to control litigation, subject to the approval of TARC, TEC or TransTexas,
as the case may be, where such compromise or settlement affects the
determination of the separate tax liability of that company.

     Under the Tax Allocation Agreement, each subsidiary's Allocable Share for
each tax year will generally equal the amount of federal income tax it would
have owed had it filed a separate federal income tax return for each year
except that each subsidiary will be able to utilize net operating losses and
credits of TransAmerican and the other members of the consolidated group
effectively to defer payment of tax liabilities that it would have otherwise
owed had it filed a separate federal income tax return. Each subsidiary will
essentially pay the deferred taxes at the time TransAmerican (or the member
whose losses or credits are utilized by such subsidiary) begins generating
taxable income or tax. This will have the effect of deferring a portion of such
subsidiary's tax liability to future years. The parties to the Tax Allocation
Agreement amended such agreement in connection with the Lobo Sale to include
additional affiliates as parties, and further amended the Tax Allocation
Agreement, in connection with the Transactions, to allocate to TransAmerican,
as among the parties, any tax liability associated with the Lobo Sale.

                   CERTAIN FEDERAL INCOME TAX CONSIDERATIONS

       The following discussion sets forth the anticipated material United
States federal income tax consequences of the exchange of Outstanding Notes for
Exchange Notes issued pursuant to the Exchange Offer. This discussion is based
upon the Code, its legislative history, existing and proposed regulations
thereunder, published rulings and court decisions, all as in effect and
existing on the date hereof and all of which are subject to change at any time,
which change may be retroactive. This discussion applies only to those persons
who purchased their Outstanding Notes from the Initial Purchaser and hold the
Notes as capital assets and does not address the tax consequences to taxpayers
who are subject to special rules (such as financial institutions, tax-exempt
organizations and insurance companies) or aspects of federal income taxation
that may be relevant to a prospective investor based upon such investor's
particular tax situation. Accordingly, holders of the Outstanding Notes should
consult their tax advisors with respect to the particular consequences to them
of the acquisition, ownership and disposition of the Exchange Notes including
the applicability of any state, local or foreign tax laws to which they may be
subject as well as with respect to the possible effects of changes in federal
and other tax laws.

ISSUANCE OF EXCHANGE NOTES

       The issuance of the Exchange Notes to Holders of the Outstanding Notes
pursuant to the terms set forth in this Prospectus should not constitute a
recognition event for federal income tax purposes.  Consequently, no gain or
loss should be recognized by Holders of the Outstanding Notes upon receipt of
the Exchange Notes.  For purposes of determining gain or loss upon the
subsequent sale or exchange of the Exchange Notes, a Holder's basis in the
Exchange Notes should be the same as such Holder's basis in the Outstanding
Notes exchanged therefor.  Holders should be considered to have held the
Exchange Notes from the time of their original acquisition of the Outstanding
Notes.

       Treasury regulations relating to the tax treatment of debt instruments
with original discount contain provisions for determining the yield and
maturity of debt instruments having one or more contingencies that could result
in the acceleration or deferral of amounts due under the debt (including
optional redemption).  The Company will follow the general rule of these
provisions, which is to ignore contingencies, as it is more likely than not
that payments will be made under the Exchange Notes under the stated payment
schedule, and thus plans to accrue and report interest on the Exchange Notes
under the stated payment schedule.

       A holder who does not tender his Outstanding Notes will not recognize
any gain or loss for United States Federal income tax purposes from the
Exchange Offer.

TAXATION OF THE NOTES

       ORIGINAL ISSUE DISCOUNT.  During the period that a holder owns a Senior
Secured Discount Exchange Note, the holder will be required to include OID in
income as if such holder continued to own the Outstanding Senior Secured
Discount Note that was exchanged therefor.  Because the Outstanding Senior
Secured Discount Notes were issued at a discount from their "stated redemption
price at maturity," the Senior Secured Discount Notes had OID for federal income
tax purposes. No OID  exists with respect to the Senior Secured Notes and, thus,
the Senior Secured Exchange Notes will not be issued with OID. The amount of OID
attributable to each Outstanding Senior Secured Discount Note  equals the excess
of the "stated redemption price at maturity" over its "issue price." The issue
price of the Outstanding Senior Secured Discount Notes was the first price at
which a substantial amount of such notes were initially sold. The stated
redemption price at maturity of an Outstanding Senior Secured Discount Note is
the sum of all payments to be made on such Outstanding Senior Secured Discount
Note, including the amount of all stated interest payments. Although the
Outstanding Senior Secured Discount Notes do not provide for the payment of
interest in cash until 1999, a holder of an Outstanding Senior Secured Discount
Note will be required to include OID in gross income in advance of the receipt
of cash attributable to such income during the initial approximate two-year
period during which the Outstanding Senior Secured Discount Notes are
outstanding. The amount and timing of such OID during this period should
correspond to the increase in the Accreted Value of the Outstanding Senior
Secured Discount Note, which is based on the semi-annual interest rate of 13%
per annum. Subsequent to the initial approximate two-year period of the





                                       93
<PAGE>   101
Outstanding Senior Secured Discount Notes, the amount of OID required to be
included by the holder of an Outstanding Senior Secured Discount Note should be
equal to the amount of scheduled interest payments received. Outstanding Senior
Secured Discount Notes issued in certificated form contain a legend that sets
forth various information concerning OID.

       More specifically, a holder of an Outstanding Senior Secured Discount
Note with OID must include in gross income for federal income tax purposes the
sum of the daily portions of OID with respect to the Outstanding Senior Secured
Discount Note for each day during the taxable year or portion of a taxable year
on which such holder holds the Outstanding Senior Secured Discount Note (such
sum, "Accrued OID"). The daily portion is determined by allocating to each day
of any accrual period within a taxable year a pro rata portion of an amount
equal to the adjusted issue price of the Outstanding Senior Secured Discount
Note at the beginning of the accrual period multiplied by the yield to maturity
of the Outstanding Senior Secured Discount Note. For purposes of computing OID,
the Company will use six-month accrual periods that end on the days in the
calendar year corresponding to the maturity date of the Outstanding Senior
Secured Discount Notes and the date six months prior to such maturity date,
with the possible exception of the initial accrual period for the Outstanding
Senior Secured Discount Notes. The adjusted issue price of an Outstanding
Senior Secured Discount Note at the beginning of any accrual period is the
issue price of the Outstanding Senior Secured Discount Note increased by the
Accrued OID for all prior accrual periods (less all payments of stated
principal and interest made on the Outstanding Senior Secured Discount Notes).

       DISPOSITION OF EXCHANGE NOTES.  Generally, any sale, redemption or other
disposition of Exchange Notes will result in taxable gain or loss equal to the
difference between (i) the amount of cash and the fair market value of other
property received and (ii) the holder's adjusted tax basis in the Exchange
Note. In the case of a holder who purchased an Outstanding Note from the
Initial Purchaser, the adjusted tax basis of an Exchange Note will initially
equal the purchase price of the Outstanding Note and in the case of a  Senior
Secured Discount Exchange Note will be increased by any Accrued OID includable
in such holder's gross income and decreased by all payments (including stated
principal and interest) received by such holder on the Exchange Note. Any gain
or loss upon a sale or other disposition of an Exchange Note will generally be
capital gain or loss, which will be long-term if the Exchange Note has been
held by the holder for more than eighteen months.
        
       SUBSEQUENT PURCHASERS.  The foregoing does not discuss special rules
which may affect the treatment of purchasers that acquire Exchange Notes other
than from a seller who did not initially acquire an Outstanding Note from the
Initial Purchaser, including those provisions of the Code relating to the
treatment of "market discount," "acquisition premium" and "amortizable bond
premium." For example, the market discount provisions of the Code may require a
subsequent purchaser of an Exchange Note at a market discount to treat all or a
portion of any gain recognized upon sale or other disposition of the Exchange
Notes as ordinary income and to defer a portion of any interest expense that
would otherwise be deductible on any indebtedness incurred or maintained to
purchase or carry such Exchange Notes until the holder disposes of the Exchange
Notes in a taxable transaction.

       FOREIGN HOLDERS.  The following discussion is a summary of certain
United States federal income tax consequences to a Foreign Person that holds an
Exchange Note. The term "Foreign Person" means a nonresident alien individual
or foreign corporation, but only if the income or gain on the Exchange Note is
not "effectively connected with the conduct of a trade or business within the
United States." If the income or gain on the Exchange Note is "effectively
connected with the conduct of a trade or business within the United States,"
then the nonresident alien individual or foreign corporation will be subject to
tax on such income or gain in essentially the same manner as a United States
citizen or resident or a domestic corporation, as discussed above, and in the
case of a foreign corporation, may also be subject to the branch profits tax.

       Under the "portfolio interest" exception to the general rules for the
withholding of tax on interest and original issue discount paid to a Foreign
Person, a Foreign Person will not be subject to United States tax (or to
withholding) on interest or original issue discount on an Exchange Note,
provided that (i) the Foreign Person does not actually or constructively own
10% or more of the total combined voting power of all classes of stock of the
Company entitled to vote and is not a controlled foreign corporation with
respect to the United States that is related to the Company through





                                       94
<PAGE>   102
stock ownership, and (ii) the Company, its paying agent or the person who would
otherwise be required to withhold tax receives either (A) a statement (an
"Owner's Statement") signed under penalties of perjury by the beneficial owner
of the Exchange Note in which the owner certifies that the owner is not a
United States person and which provides the owner's name and address, or (B) a
statement signed under penalties of perjury by the Financial Institution
holding the Exchange Note on behalf of the beneficial owner, together with a
copy of the Owner's Statement. The term "Financial Institution" means a
securities clearing organization, bank or other financial institution that
holds customers' securities in the ordinary course of its trade or business and
that holds an Exchange Note on behalf of the owner of the Exchange Note. A
Foreign Person who does not qualify for the "portfolio interest" exception
would, under current law, generally be subject to United States withholding tax
at a flat rate of 30% (or a lower applicable treaty rate) on interest payments
and payments (including redemption proceeds) attributable to original issue
discount on the Exchange Notes.

       In general, gain recognized by a Foreign Person upon the redemption,
sale or exchange of an Exchange Note (including any gain representing accrued
market discount) will not be subject to United States tax. However, a Foreign
Person may be subject to United States tax at a flat rate of 30% (unless exempt
by applicable treaty) on any such gain if the Foreign Person is an individual
present in the United States for 183 days or more during the taxable year in
which the Exchange Note is redeemed, sold or exchanged, and certain other
requirements are met.

BACKUP WITHHOLDING

       A holder may be subject, under certain circumstances, to backup
withholding at a 31% rate with respect to payments received with respect to the
Exchange Notes. This withholding generally applies only if the holder (i) fails
to furnish his or her social security or other taxpayer identification number
("TIN"), (ii) furnishes an incorrect TIN, (iii) is notified by the IRS that he
or she has failed to report properly payments of interest and dividends and the
IRS has notified the Company that he or she is subject to backup withholding or
(iv) fails, under certain circumstances, to provide a certified statement,
signed under penalty of perjury, that the TIN provided is his or her correct
number and that he or she is not subject to backup withholding. Any amount
withheld from a payment to a holder under the backup withholding rules is
allowable as a credit against such holder's federal income tax liability,
provided that the required information is furnished to the IRS. Certain holders
(including, among others, corporations and foreign individuals who comply with
certain certification requirements described above under "Foreign Holders") are
not subject to backup withholding. Holders should consult their tax advisors as
to their qualification for exemption from backup withholding and the procedure
for obtaining such an exemption.


                          CERTAIN LEGAL CONSIDERATIONS

CANCELLATION OF DEBT ISSUES

       Part of the refinancing of TransAmerican's debt in 1993 involved the
cancellation of approximately $65.9 million of accrued interest and of a
contingent liability for interest of $102 million owed by TransAmerican.
TransAmerican has taken the federal tax position that the entire amount of this
debt cancellation is excluded from its income under the COD Exclusion.
TransAmerican has reduced its tax attributes (including its net operating loss
and credit carryforwards) as a consequence of the COD Exclusion. Although
TransTexas believes that there is substantial legal authority to support the
position that the COD Exclusion applies to the cancellation of TransAmerican's
indebtedness due to factual and legal uncertainties, there can be no assurance
that the IRS will not challenge this position, or that any such challenge would
not be upheld. Under the Tax Allocation Agreement, TransTexas has agreed to pay
an amount equal to any federal tax liability (which would be approximately
$25.4 million) attributable to the inapplicability of the COD Exclusion. Any
such tax would be offset in future years by alternative minimum tax credits and
retained loss and credit carryforwards to the extent recoverable from
TransAmerican. The IRS has commenced an audit of the consolidated federal
income tax returns of the TNGC Consolidated Group for its taxable years ended
July 31, 1994, and July 31, 1995. Because the audit is in its initial stages,
it is not possible to predict the scope of the IRS' review and whether any tax
deficiencies will be proposed by the IRS as a result of its review.





                                       95
<PAGE>   103
RECOGNITION OF GAIN AND DEDUCTION OF COSTS

       If a transfer or other disposition occurs of an amount of TransTexas
common stock that results in the members of the TNGC Consolidated Group
(excluding TransTexas) in the aggregate owning less than 80% of the voting power
and 80% of the stock value of TransTexas, then a Deconsolidation of TransTexas
would occur. Upon a Deconsolidation of TransTexas, members of the TNGC
Consolidated Group that own TransTexas common stock could incur a substantial
amount of federal income tax liability. If such Deconsolidation occurred during
the fiscal year ending January 31, 1998, the aggregate amount of this tax
liability is estimated to be between $50 million and $100 million, assuming no
reduction for tax attributes of the TNGC Consolidated Group. However, such tax
liability generally would be substantially reduced or eliminated in the event
that the IRS successfully challenged TransTexas' position on the Lobo Sale. If
TARC were no longer a member of the TNGC Consolidated Group, TransTexas would
also no longer be a member of the TNGC Consolidated Group based on the Company's
anticipated level of ownership of TransTexas stock. Further, if a spin-off of
TTXD occurs and is a taxable event, TransTexas would recognize a significant
deferred gain, which TransTexas would include in income upon a Deconsolidation
of TransTexas or upon a disposition outside the TNGC Consolidated Group of the
TTXD stock that initially was distributed to group members, and the tax
liability resulting from a Deconsolidation of TransTexas of TNGC Consolidated
Group members also would be increased. Moreover, a distribution of TransTexas
common stock by TARC would create gain to TARC that would not be taken into
income until either a Deconsolidation of TARC or upon a disposition of the
distributed common stock outside of the TNGC Consolidated Group.

       Likewise, if TransAmerican, the Company or TARC sells or otherwise
disposes of stock of TransTexas outside of the TNGC Consolidated Group, the
selling corporation will recognize gain (which would not be deferred under the
consolidated return regulations) equal to the excess (if any) of the fair
market value of the TransTexas stock disposed of over the seller's basis (if
any) in such stock. It is possible that any shares of TransTexas stock sold by
the TNGC Consolidated Group will have no basis.

       The Tax Allocation Agreement has been revised to require TNGC,
TransAmerican, the Company, TransTexas and TARC to file federal income tax
returns as members of the TNGC Consolidated Group. Corporations that are
members of a federal consolidated group are generally severally liable for the
federal tax of the entire group.

       TransTexas and TARC intend to deduct currently the excess of the price
paid to redeem the TransTexas Senior Secured Notes and the TARC Discount Notes,
respectively, over the principal amount and the accreted amount (as applicable)
of such notes as redemption premium. If the IRS were to argue successfully
that, taking into account the issuance of the Outstanding Senior Secured
Discount Notes and the Outstanding Senior Secured Notes, the redemption of the
TransTexas Senior Secured Notes and the TARC Discount Notes should be treated
as a debt for debt exchange, it is possible that TransTexas and TARC would be
required to amortize and deduct the applicable redemption premiums ratably over
the terms of the Outstanding Notes. Moreover, deductibility of the redemption
premiums may be subject to other limitations. TEC believes, however, that the
redemption of the TransTexas Senior Secured Notes and the TARC Discount Notes
should be treated as a cash redemption rather than a debt for debt exchange and
that the redemption premiums constitute deductible interest, thereby entitling
TransTexas and TARC to deduct the redemption premium in the year the redemption
occurs.

STATE TAX

       Under the Tax Allocation Agreement, TransTexas is required to pay Texas
franchise tax (which is estimated not to exceed $11.4 million) attributable to
prior year transactions. TransTexas paid approximately $5.4 million of such tax
as of the closing date of the Lobo Sale and will pay a substantial amount of
the remaining tax within the ensuing twelve-month period.

                      DESCRIPTION OF EXISTING INDEBTEDNESS

TRANSTEXAS

       TRANSTEXAS SUBORDINATED NOTES. TransTexas has outstanding approximately
$116 million in principal amount of TransTexas Subordinated Notes.  TransTexas
has filed a registration statement to register the exchange of the TransTexas
Subordinated Notes for subordinated notes with terms substantially identical to
the TransTexas Subordinated Notes.  The TransTexas Subordinated Notes bear cash
interest at the rate of 13  3/4% per annum, payable semi-annually in arrears on
June 30 and December 31 of each year, commencing December 31, 1997. Upon the
occurrence of a TTXD Spinoff (as defined in the Indenture) through a pro rata
distribution or dividend to TransTexas' common stockholders, the interest rate
on the TransTexas Subordinated Notes would increase to 14 1/8% and TransTexas
will issue to each holder of TransTexas Subordinated Notes in principal amount
equal to 1 1/2% of the aggregate principal amount of TransTexas Subordinated
Notes held by such holder.  The Subordinated Notes Indenture contains
restrictive covenants including, among others, limitations on incurring
additional debt, asset sales, dividends and transactions with affiliates.

       TRANSTEXAS RECEIVABLES FACILITY.  TransTexas and BNY Financial
Corporation are parties to an Amended and Restated Accounts Receivable
Management and Security Agreement (the "BNY Facility"), dated as of October 31,
1995 and amended in December 1996.  In connection with the Lobo Sale, the TEC
Notes Offering and the Transactions,  TransTexas and BNY entered into a waiver
of the BNY Facility, pursuant to which advances under the BNY Facility are made
at the sole discretion of the lender and the lender may require repayment of
principal and interest at any time.  As of July 31, 1997, outstanding advances
under the BNY Facility totaled approximately $6.2 million.  Interest accrues on
advances at the rate of (i) the higher of (a) the prime rate of The Bank of New
York or (b) the Federal Funds Rate plus  1/2 of 1% plus (ii)  1/2 of 1%.
Obligations under the BNY Facility are secured by liens on TransTexas'
receivables and inventory.  TransTexas is currently negotiating an amendment
and restatement of the BNY Facility.

TARC

       TARC NOTES. As of July 31, 1997, TARC has outstanding $15.7 million in
aggregate carrying value of the TARC Notes.  Cash interest does not accrue on
the TARC Discount Notes prior to February 15, 1998. Commencing August 15, 1998,
cash interest on the TARC Discount Notes is payable semi-annually on February
15 and August 15 at a rate of 18  1/2% per annum, subject to adjustment. The
TARC Mortgage Notes bear interest at the rate of 16  1/2% per annum, subject to
adjustment, payable semi-annually on February 15 and August 15. Upon payment in
full in cash of the interest payment due on August 15, 1998, in respect of the
TARC Discount Notes, the TARC Discount Notes and the TARC Mortgage Notes will
thereafter bear interest at the respective rates per annum set forth above less
50 basis points. The TARC Notes will mature on February 15, 2002.  The TARC
Notes Indenture contains restrictive covenants, including limitations on TARC's
ability to transfer or sell assets or consummate a merger, consolidation or
sale of all or substantially all of its assets.

                       DESCRIPTION OF THE EXCHANGE NOTES

       The Exchange Notes will be issued as a separate series of notes pursuant
to an indenture, dated as of June 13, 1997 (the "Indenture" or "TEC Notes
Indenture"), by and between the Company and Firstar Bank of Minnesota, N.A., as
trustee (the "Trustee"). The Exchange Notes are substantially identical
(including principal amount, interest rate, maturity and redemption rights) to
the Outstanding Notes for which they may be exchanged pursuant to this offer,
except for certain transfer restrictions and registration rights relating the
Outstanding Notes and except for certain interest provisions relating to such
rights.  Under the terms of the Indenture, the covenants and events of default
will apply equally to the Exchange Notes and the Outstanding Notes, and the
Exchange Notes and the Outstanding Notes will be treated as one class for all
actions to be taken by the holders thereof and for determining their respective
rights under the Indenture.  References to the Notes include the Exchanges
Notes and the Outstanding Notes unless the context otherwise requires.  The
terms of the Indenture are also governed by certain provisions contained in the
Trust Indenture Act of 1939, as amended. The following summaries of certain
provisions of the Indenture, the Disbursement Agreement (as defined) and the
Security Documents (as defined) are summaries only, do not purport to be
complete, and are





                                       97
<PAGE>   105
qualified in their entirety by reference to all of the provisions of the
Indenture, the Disbursement Agreement or the Security Documents, as applicable.
A copy of the Indenture, Disbursement Agreement and Security Documents have
been filed as exhibits to the Registration Statement of which this Prospectus
is a part. Capitalized terms used herein and not otherwise defined shall have
the meanings assigned to them in the Indenture. References to the "Company" as
used in this "Description of the Notes" are to TransAmerican Energy
Corporation.

GENERAL

       The Notes are senior secured obligations of the Company and will rank
pari passu in right of payment to any future senior indebtedness and are senior
in right of payment to any subordinated indebtedness of the Company. The Notes
will be issued only in fully registered form, without coupons, in denominations
of $1,000 and integral multiples thereof.

       The Notes will mature on June 15, 2002. The Senior Secured Exchange
Notes will bear interest at the rate of 11 1/2% per annum from the date of
issuance of the Outstanding Senior Secured Notes or from the most recent
Interest Payment Date to which interest has been paid or provided for, payable
semi-annually in cash in arrears on June 15 and December 15 of each year,
commencing December 15, 1997, to the persons in whose names such Senior Secured
Exchange Notes are registered at the close of business on the June 1 or
December 1 preceding such Interest Payment Date. The Outstanding Senior Secured
Discount Notes were issued at a substantial discount from their principal
amount.  The Senior Secured Discount Notes will accrete from the date of their
original issuance (June 13, 1997 for the Outstanding Senior Secured Discount
Notes and the Exchange Date for the Senior Secured Discount Exchanges Notes)
until June 15, 1999.  On their issue date, the Senior Secured Discount Exchange
Notes will have the same Accreted Value per $1,000 face amount as the
Outstanding Senior Secured Discount Notes on such date.  After June 15, 1999
the Senior Secured Discount Notes will bear cash interest at the rate of 13%
per annum, payable semi-annually on June 15 and December 15 of each year,
commencing December 15, 1999, to the persons in whose names such Senior Secured
Discount Notes are registered at the close of business on the June 1 or
December 1 preceding such Interest Payment Date. Interest on the Notes will be
paid on the basis of a 360-day year consisting of twelve 30-day months.

       Principal of, premium, if any, and interest on the Notes will be
payable, and the Notes may be presented for registration of transfer or
exchange, at the office or agency of the Company maintained for such purpose in
New York, New York, and such other office or agency of the Company as may be
maintained for such purpose. At the option of the Company, payment of interest
may be made by check mailed to the Holders of the Notes at the addresses set
forth upon the registry books of the Company. No service charge will be made
for any registration of transfer or exchange of the Notes, but the Company may
require payment of a sum sufficient to cover any tax or other governmental
charge payable in connection therewith. Until otherwise designated by the
Company, the Company's office or agency will be the principal corporate trust
office of the Indenture Trustee presently located in New York, New York.

       The Company's operations are, or are expected to be, conducted through
TransTexas, TARC and TTXD. Any right of the Company to receive assets of
TransTexas, TARC, TTXD or any of their Subsidiaries upon their liquidation or
recapitalization (and the consequent right of holders of the Notes to
participate in those assets) will be subordinate to the claims of creditors of
TransTexas, TARC, TTXD or any of their Subsidiaries, as applicable, except to
the extent that the Company is itself recognized as a creditor of such entity.
The ability of the Company to pay principal of and interest on the Notes is
dependent upon the earnings of TransTexas, TARC, TTXD and their Subsidiaries
and the distribution of those earnings to the Company, the payment of
obligations under the TransTexas Intercompany Loan and the TARC Intercompany
Loan or upon loans or advances made by TransTexas, TARC, TTXD or any of their
Subsidiaries to the Company or by sale of the stock of the Company's
Subsidiaries. See "Risk Factors -- General Risk Factors -- Holding Company
Structure."

DISBURSEMENT OF FUNDS; DISBURSEMENT ACCOUNTS

       Pursuant to a disbursement agreement (the "Disbursement Agreement")
among TARC, the Company, Firstar Bank of Minnesota, N.A., as disbursement agent
(the "Disbursement Agent"), the Trustee and Baker & O'Brien, Inc., as
construction supervisor (the "Construction Supervisor"), approximately $284
million from the Transactions was or will be placed in an account (the "TARC
Disbursement Account"), to be held and invested by the Disbursement Agent until
satisfaction of the disbursement conditions set forth in the Disbursement
Agreement. In addition, TARC deposited the unused portion of funds allocated to
the repurchase of the TARC Notes (the "TARC Note Funds") in the TARC
Disbursement Account. Pursuant to the Disbursement Agreement, the Company also
will deposit approximately $226 million in an account (the "TEC Disbursement
Account" and together with the TARC Disbursement Account, the "Disbursement
Accounts"). The Disbursement Agent will invest the assets of the Disbursement
Accounts in cash or Cash Equivalents (as defined) as specifically directed in
writing by the Company. Interest income, if any, earned on the invested
proceeds will be added to the balance of the Disbursement Accounts. The
Disbursement Agent will disburse funds from the Disbursement Accounts only upon
satisfaction of the disbursement conditions set forth in the Disbursement
Agreement. All funds in the TARC Disbursement Account and the TEC Disbursement
Account will be pledged as security for the repayment of the TARC Intercompany
Loan and the Notes, respectively.

       Baker & O'Brien is a professional consulting firm serving the energy,
chemical, and related industries. Although Baker & O'Brien has performed and is
currently performing consulting services for TARC and affiliates of TARC, it is
an independent consultant and has no affiliation with TARC. Baker & O'Brien was
retained by the Initial Purchaser to provide an independent review of the plans
of TARC to reactivate and upgrade its petroleum refinery.

       The Disbursement Agent will make disbursements out of the Disbursement
Accounts in accordance with a budget prepared by TARC and approved by the
Construction Supervisor. The budget consists of an itemized schedule setting
forth the additional expenditures estimated to be incurred in connection with
the Capital Improvement Program. TARC may reallocate expenditures to line items
within Phase I or line items within Phase II or may reallocate from Phase II to
Phase I but may not reallocate expenditures budgeted for Phase I to Phase II
until Phase I is completed.

       Under the Disbursement Agreement, the Construction Supervisor is
responsible for review and approval of TARC's plans and specifications and
budget for the Capital Improvement Program. In addition, the Construction
Supervisor is required to review each request by TARC for a disbursement from
the Disbursement Accounts. No disbursements may be made from either
Disbursement Account to fund the Capital Improvement Program unless the
Construction Supervisor determines (i) that the disbursement has been requested
to pay for expenses that are in accordance with the plans and specifications
approved by the Construction Supervisor, pursuant to the terms of the budget,
and (ii) that transactions for which a disbursement has been requested were
made on an arm's length basis or on a basis at least as favorable to TARC as
could have been obtained on an arm's length basis, as represented by TARC. No
disbursements may be made from either Disbursement Account for purposes other
than the Capital Improvement Program other than (i) up to $1.5 million per
month (except for December 1997, in which disbursements may be up to $4.5
million) to fund administrative costs and certain taxes and insurance payments,
not in excess of $25.5 million in the aggregate; provided, that if less than
$1.5 million is spent in any month (or less than $4.5 million is spent in
December 1997) the amounts which may be disbursed in one or more subsequent
months will be increased by the amount of such difference, (ii) up to $50
million for feedstock upon certification by the Construction Supervisor of the
Mechanical Completion of the Delayed Coking Unit and associated facilities,
(iii) the TARC Note Funds to redeem or otherwise retire the TARC Notes and (iv)
up to $7.0 million for outstanding accounts payable. In addition, interest
income from the Disbursement Accounts may be used for the Capital Improvement
Program or disbursed to fund administrative and other costs of TARC or the
Company including, without limitation, costs incurred pursuant to the Services
Agreement.

       Pursuant to a disbursement agreement (the "TransTexas Disbursement
Agreement") among TransTexas, the Company and Firstar Bank of Minnesota, N.A.,
as disbursement agent (the "TransTexas Disbursement Agent"), approximately $399
million was placed in an account (the "TransTexas Disbursement Account"), to be
held and invested by the TransTexas Disbursement Agent for use by TransTexas
solely to make share repurchases pursuant to





                                       99
<PAGE>   107
the TransTexas Share Repurchase Program. Any funds remaining in the TransTexas
Disbursement Account after the Phase II Completion Date may be used by
TransTexas for general corporate purposes. The TransTexas Disbursement Agent
will invest the assets of the TransTexas Disbursement Account in cash or Cash
Equivalents (as defined) as specifically directed in writing by TransTexas.
Interest income, if any, earned on the invested proceeds will be added to the
balance of the TransTexas Disbursement Account but may be disbursed to
TransTexas at any time and used by TransTexas for general corporate purposes.
The TransTexas Disbursement Agent will disburse funds from the TransTexas
Disbursement Account only upon satisfaction of the disbursement conditions set
forth in the TransTexas Disbursement Agreement. As of September 15, 1997,
approximately $262.4 million had been disbursed from the TransTexas
Disbursement Account.  All funds in the TransTexas Disbursement Account are
pledged as security for the repayment of the TransTexas Intercompany Loan.

       In the case of a partial redemption, the Company may elect to redeem
from either the Senior Secured Notes or the Senior Secured Discount Notes or a
combination thereof, and the Indenture Trustee shall select the Notes to be
redeemed from within the Senior Secured Notes or the Senior Secured Discount
Notes pro rata or by lot or in such other manner as in its sole discretion it
deems appropriate and fair. The Notes may be redeemed in part in multiples of
$1,000 principal amount only.

       Notice of any redemption will be sent, by first class mail at least 15
days and not more than 60 days prior to the date fixed for redemption, to the
Holder of each Note to be redeemed to such Holder's last address as then shown
upon the registry books of the Registrar. Any notice which relates to a Note to
be redeemed in part only must state the portion of the principal amount equal
to the unredeemed portion thereof and must state that on and after the date
fixed for redemption, upon surrender of such Note, a new Note, or Notes in a
principal amount equal to the unredeemed portion thereof will be issued. The
date fixed for redemption contained in any notice of redemption and the
obligation of the Company to redeem any Notes upon such date may be subject to
the satisfaction or waiver of conditions determined by the Company in its sole
discretion. On and after the date fixed for redemption, unless the Company
defaults on its payment obligations or any conditions contained in the notice
of redemption are not satisfied or waived, interest will cease to accrue and/or
the original issue discount will cease to accrete on the Notes or portions
thereof called for redemption.

       the lesser of (x) the principal amount of the Debt being extended,
       renewed, replaced, or refunded plus Refinancing Fees, or (y) if such
       Debt being extended, renewed, replaced, or refunded was issued at an
       original issue discount, the original issue price, plus amortization of
       the original issue discount as of the time of the Incurrence of the TEC

Disqualified Capital Stock if, at the time such Senior Debt is Incurred or such
Disqualified Capital Stock is Issued, (i) no Default or Event of Default shall

to such transaction on a pro forma basis, and (ii) immediately after giving
effect to

of any Subsidiary which was formerly designated as an Unrestricted Subsidiary).

       Notwithstanding the foregoing provisions of this covenant, (a) TARC may
Incur Senior Debt and TARC may issue Disqualified Capital Stock if, at the time
such Senior Debt is Incurred or such Disqualified Capital Stock is issued, (i)
no Default or Event of Default shall have occurred and be continuing at the

       Debt Incurred and Disqualified Capital Stock issued by any Person that
is not a Subsidiary of TransTexas or TARC, as the case may be, which Debt or
Disqualified Capital Stock is outstanding at the time such Person becomes a
Subsidiary of, or is merged into, or consolidated with TransTexas or TARC or
one of their Subsidiaries, as the case may be, shall be deemed to have been
Incurred or issued, as the case may be, at the time such Person becomes a
Subsidiary of, or is merged into, or consolidated with TransTexas or TARC,
respectively, or one of their respective Subsidiaries.

       For the purpose of determining compliance with this covenant, (A) if an
item of Debt meets the criteria of more than one of the types of Debt described
in the above clauses, the Company or the Subsidiary in question shall have the
right to determine in its sole discretion the category to which such Debt
applies and shall not be required to include the amount and type of such Debt
in more than one of such categories and may elect to apportion such item of
Debt between or among any two or more of such categories otherwise applicable,
and (B) the amount of any Debt which does not pay interest in cash or which was
issued at a discount to face value shall be deemed to be equal to the amount of
the liability in respect thereof determined in accordance with GAAP.

       Limitation on Restricted Payments. The Indenture provides that the
Company will not, and will not permit any of its Subsidiaries (other than any
of the TTXD Entities after the TTXD Spin-off) to, directly or indirectly, make
any dividend or other distribution on shares of Capital Stock of the Company or
any Subsidiary of the Company or make any payment on account of the purchase,
redemption, or other acquisition or retirement for value of any such shares of
Capital Stock (except (x) to TransTexas by any of its Subsidiaries or (y) to
TARC by any of its Subsidiaries) unless such dividends, distributions, or
payments are made in cash or Capital Stock or a combination thereof (other than
the TTXD Spin-off or a dividend of the common stock of TransTexas by TARC to
the Company). In addition, the Indenture provides that the Company will not,
and will not permit any of its Subsidiaries (other than any of the TTXD
Entities after the TTXD Spin-off) to, directly or indirectly, make any
Restricted Payment; provided, however, that TransTexas





                                      133
<PAGE>   141
or TARC may make a Restricted Payment if, at the time or after giving effect
thereto on a pro forma basis no Default or Event of Default would occur or be
continuing, and:

       (i)    in the case of Restricted Payments by TransTexas:

              (a) the Consolidated Fixed Charge Coverage Ratio of TransTexas

       Subsidiaries (excluding, for purposes of the calculation of Debt, any
       Swap Obligations); and

              (c) the aggregate amount of all Restricted Payments made by
       TransTexas and its Subsidiaries, including such proposed Restricted
       Payment and all payments that may be made pursuant to the proviso at the
       end of this sentence (if not made in cash, then the fair market value of
       any property used therefor) from and after the Issue Date and on or
       prior to the date of such Restricted Payment, would not exceed the sum
       of (x) 25% of Adjusted Consolidated Net Income of TransTexas accrued for
       the period (taken as one accounting period), commencing with the first
       full fiscal quarter that commenced after the Issue Date, to and
       including the fiscal quarter ended immediately prior to the date of each
       calculation (or, in the event Adjusted Consolidated Net Income for such
       period is a deficit, then minus 100% of such deficit), minus (y) 100% of
       the amount of any write-downs, write-offs, other negative revaluations,
       and other negative extraordinary charges not otherwise reflected in
       Adjusted Consolidated Net Income of TransTexas during such period, plus
       (z) the aggregate Net Proceeds received by TransTexas from the issuance
       or sale (other than to the Company or a Subsidiary of the Company) of
       its Qualified Capital Stock from and after the Issue Date and on or
       prior to the date of such Restricted Payment); or

       (ii)   in the case of Restricted Payments by TARC:

              (a) TARC's Consolidated Fixed Charge Coverage Ratio exceeds 2.25
       to 1; and

              (b) the aggregate amount of all Restricted Payments made by all
       of the TARC Entities, including such proposed Restricted Payment and all
       payments that may be made pursuant to the proviso at the end of this
       sentence (if not made in cash, then the fair market value of any
       property used therefor), from and after the Issue Date and on or prior
       to the date of such Restricted Payment, would not exceed an amount equal
       to (x) 25% of Adjusted Consolidated Net Income of TARC accrued for the
       period (taken as one accounting period) from the first full fiscal
       quarter that commenced after the Issue Date to and including the fiscal
       quarter ended immediately prior to the date of each calculation for
       which financial statements are available (or, if TARC's Adjusted
       Consolidated Net Income for such period is a deficit, then minus 100% of
       such deficit), plus (y) the aggregate Net Proceeds received by TARC from
       the issuance or sale (other than to the Company or a Subsidiary of the
       Company) of its Qualified Capital Stock from and after the Issue Date
       and on or prior to the date of such Restricted Payment, minus (z) 100%
       of the amount of any write-downs, write-offs, other negative
       revaluations, and other negative extraordinary charges not otherwise
       reflected in TARC's Adjusted Consolidated Net Income during such period;
       and

provided, that the foregoing clauses will not prohibit the payment of any
dividend within 60 days after the date of its declaration if such dividend
could have been made on the date of its declaration in compliance with the
foregoing provisions.

       Subsidiaries to, make Investments in an Accounts Receivable Subsidiary
       (i) the proceeds of which are applied within five Business Days of the
       making thereof solely to finance the





                                      134
<PAGE>   142
       purchase of accounts receivable of TARC and its Subsidiaries and (ii) in
       the form of Accounts Receivable Subsidiary Notes to the extent permitted

       Investments shall not exceed the greater of $20 million or 20% of the
       TARC Borrowing Base at any time;

              (b) TARC may not, nor may it permit any of its Subsidiaries to,
       sell accounts receivable to an Accounts Receivable Subsidiary except for
       consideration in an amount not less than that which would be obtained in
       an arm's length transaction and solely in the form of cash or Cash
       Equivalents; provided that an Accounts Receivable Subsidiary may pay the
       purchase price for any such accounts receivable in the form of Accounts
       Receivable Subsidiary Notes so long as, after giving effect to the
       issuance of any such Accounts Receivable Subsidiary Notes, the aggregate
       principal amount of all Accounts Receivable Subsidiary Notes outstanding
       shall not exceed the greater of $20 million or 20% of the aggregate
       purchase price paid for all outstanding accounts receivable purchased by
       an Accounts Receivable Subsidiary since the date of this Indenture (and
       not written off or required to be written off in accordance with the
       normal business practice of an Accounts Receivable Subsidiary);

              (c) The Company shall not permit an Accounts Receivable
       Subsidiary to sell any accounts receivable purchased from TARC and its
       Subsidiaries or participation interests therein to any other Person
       except on an arm's length basis and solely for consideration in the form
       of cash or Cash Equivalents;

              (d) The Company may not, nor may it permit any of its
       Subsidiaries to, enter into any guarantee, subject any of their
       respective properties or assets (other than the accounts receivable sold
       by them to an Accounts Receivable Subsidiary or a guarantee limited in
       recourse solely to the stock of an Accounts Receivable Subsidiary) to
       the satisfaction of any liability or obligation or otherwise incur any
       liability or obligation (contingent or otherwise), in each case, on
       behalf of an Accounts Receivable Subsidiary or in connection with any
       sale of accounts receivable or participation interests therein by or to
       an Accounts Receivable Subsidiary, other than obligations relating to
       breaches of representations, warranties, covenants, and other agreements

       therein of TARC and its Subsidiaries and activities incidental thereto,
       including incurring Debt pursuant to clause (f) below;

              (f) The Company shall not permit an Accounts Receivable
       Subsidiary to incur any Debt other than the Accounts Receivable
       Subsidiary Notes, Debt owed to TARC, and Non-Recourse Debt; provided
       that the aggregate principal amount of all such Debt of an Accounts
       Receivable Subsidiary shall not exceed the book value of its total
       assets as determined in accordance with GAAP;

              (g) The Company shall cause any Accounts Receivable Subsidiary to

       cash and Cash Equivalents not held in a collection account pledged to
       lenders, acquirors of accounts receivable or participation interests
       therein, to the extent not applied to (i) pay interest or principal on

       Receivable Subsidiary permitted by clause (f) above, (ii) pay or
       maintain reserves for reasonable operating expenses of such Accounts

                                      135
<PAGE>   143
                 (h) TARC may not, nor may it permit any of its Subsidiaries
         to, sell accounts receivable to, or enter into any such transaction
         with or for the benefit of, an Accounts Receivable Subsidiary (i) if
         such Accounts Receivable Subsidiary pursuant to or within the meaning
         of any Bankruptcy Law (A) commences a voluntary case, (B) consents to
         the entry of an order for relief against it in an involuntary case,
         (C) consents to the appointment of a Custodian of it or for all or
         substantially all of its property, (D) makes general assignment for
         the benefit of its creditors, or (E) generally is not paying its debts
         as they become due; or (ii) if a court of competent jurisdiction
         enters an order or decree under any Bankruptcy Law that (A) is for
         relief against such Accounts Receivable Subsidiary in an involuntary
         case, (B) appoints a Custodian of such Accounts Receivable Subsidiary
         or for all or substantially all of the property of such Accounts
         Receivable Subsidiary, or (C) orders the liquidation of such Accounts
         Receivable Subsidiary, and, with respect to clause (ii) hereof, the
         order or decree remains unstayed and in effect for 60 consecutive
         days.

         Limitation on Restricting Subsidiary Dividends. The Indenture provides
that the Company may not, and may not permit any of its Subsidiaries (other
than TARC, TransTexas or any of the TTXD Entities) to, directly or indirectly,
create, assume, or suffer to exist any consensual encumbrance or restriction on
the ability of any Subsidiary of the Company (other than TARC, TransTexas or
any of the TTXD Entities) to pay dividends or make other distributions on the
Capital Stock of any Subsidiary of the Company, except encumbrances and
restrictions existing under this Indenture and any agreement of a Person
acquired by the Company or a Subsidiary of the Company, which restrictions
existed at the time of acquisition, were not put in place in anticipation of
such acquisition and are not applicable to any Person or property, other than
the Person or any property of the Person so acquired. Notwithstanding anything
contained herein to the contrary, neither TARC nor TransTexas may create an
encumbrance or restriction on their ability to pay premium, if any, principal
of, or interest on, the Intercompany Loans.

         Guarantee by Subsidiaries. The Indenture provides that if TARC or
TransTexas or any of their respective Subsidiaries shall make Investments in an
aggregate amount, or otherwise transfer (including by capital contribution) or
cause to be transferred, in a manner otherwise permitted pursuant to the
Indenture, any assets (tangible or intangible), businesses, divisions, real
property, or equipment having a book value as shown in the Company's most
recent consolidated balance sheet or the notes thereto (or if greater, a fair
market value at the time of transfer) in excess of $1 million in or to any
Subsidiary that is not a Guarantor or an obligor on either the TransTexas
Intercompany Loan or the TARC Intercompany Loan, other than TTXD or any
Subsidiary of TTXD after the TTXD Spin-off, the Company shall (a) cause such
transferee Subsidiary to (x) guarantee payment of the TransTexas Intercompany
Loan, in the case of Subsidiaries of TransTexas, or the TARC Intercompany Loan
in the case of Subsidiaries of TARC, by executing a Guarantee and (y) execute
the appropriate security document, in substantially the form of the relevant
Security Document, necessary to grant a security interest in all of the assets
of such Subsidiary (other than Equipment, Inventory and Receivables) to secure
such Guarantee and (b) deliver to the Indenture Trustee an Opinion of Counsel,
in form reasonably satisfactory to the Indenture Trustee, that such Guarantee
is a valid, binding and enforceable obligation of such Subsidiary, subject to
customary exceptions for bankruptcy, fraudulent transfer and equitable
principles. If TARC or TransTexas or any of their Subsidiaries shall
subsequently sell or otherwise transfer all of the Capital Stock of such
Subsidiary held by TARC, TransTexas or any of their Subsidiaries, the Guarantee
required hereby shall be withdrawn or canceled. In addition, if the TTXD
Spin-off has occurred the Guarantee by TTXD or any of its Subsidiaries shall be
withdrawn or cancelled.

         The liability of each Guarantor under its Guarantee will be limited to
the amount of its Adjusted Net Assets.  The limitation is intended to protect
the Guarantees from avoidance as fraudulent transfers, although there can be no
assurance that the limitation will successfully do so. See "Risk Factors --
General Risk Factors -- Fraudulent Transfer Considerations." Each Guarantor
that makes a payment under its Guarantee of the TARC Intercompany Loan or the
TransTexas Intercompany Loan shall be entitled to assert a claim for
reimbursement from each other Guarantor of the respective Intercompany Loan, in

tendered are purchased and paid for in accordance with the Indenture, which
date shall be no later than 25 Business Days after the first date on which the

<PAGE>   148
Business Days prior to the close of business on the third Business Day prior to
the Excess Cash Purchase Date (the "Final Put Date"), by first-class mail, by
the Company to each Holder at the address on the books of the Note Registrar,
with a copy to the Indenture Trustee. The notice to the Holders will contain
all information, instructions, and materials required by applicable law or
otherwise material to such Holders' decision to tender Notes pursuant to the
Excess Cash Offer. An amount equal to the aggregate of all Excess Cash received
by the Company is referred to as the "Accumulated Amount." Prior to making any
Excess Cash Offer, the Company shall invest the Accumulated Amount only in cash
and Cash Equivalents. The Company may, at its option, elect to make an Excess
Cash Offer in the manner specified herein prior to the time that the
Accumulated Amount exceeds $50 million.

         To the extent applicable and if required by law, the Company shall
comply with Section 14 of the Exchange Act and the provisions of Regulation 14E
and any other tender offer rules under the Exchange Act and other securities
laws, rules, and regulations which may then be applicable to any Excess Cash
Offer by the Company to purchase the Notes. The Company shall give the
Indenture Trustee prompt notice if the Accumulated Amount exceeds $50 million.

         On or before an Excess Cash Purchase Date, the Company shall (a)
accept for payment Notes or portions thereof properly tendered pursuant to the

Value of the Notes actually tendered if Notes with a Value in excess of the
Value of Notes to be acquired are tendered and not withdrawn), (b) deposit with
the Paying Agent U.S. Legal Tender sufficient to pay the Excess Cash Offer
Price through the Excess Cash Purchase Date of all Notes or portions thereof so
accepted, and (c) deliver to the Indenture Trustee Notes so accepted together
with an Officers' Certificate stating the Notes or portions thereof being
purchased by the Company. The Paying Agent shall promptly mail or deliver to
Holders of Notes so accepted, payment in an amount equal to the Excess Cash
Offer Price through the Excess Cash Purchase Date for such Notes. The Indenture
Trustee shall promptly cancel all Notes accepted by the Company pursuant to the
Excess Cash Offer and authenticate and mail or deliver to the Holders of Notes
so accepted a new Note equal in Value to any unpurchased portion of the Note
surrendered. Any Notes not so accepted shall be promptly mailed or delivered by
the Company to the Holder thereof. The Company will publicly announce the
results of the Excess Cash Offer on or as soon as practicable after the Excess
Cash Payment Date.

         If the amount required to acquire all Notes tendered by Holders
pursuant to the Excess Cash Offer (the "Excess Cash Acceptance Amount") shall
be less than the aggregate Excess Cash Offer Amount, the excess of the Excess
Cash Offer Amount over the Excess Cash Acceptance Amount may be (i) invested in
cash or Cash Equivalents, (ii) used by the Company to make a Note Repurchase or
(iii) used by the Company to make loans to its Subsidiaries, provided that such
loans (x) are on terms no less favorable to the Company than the economic terms
described to the Holders of Notes in the Excess Cash Offer, (y) are made to the
parties described in the Excess Cash Offer, and (z) have a maturity date which
is not after the maturity date of the Notes. Upon consummation of any Excess
Cash Offer made in accordance with the terms of the Indenture, the Accumulated
Amount will be reduced to zero.

         Notwithstanding anything contained in the foregoing to the contrary,
the Company shall immediately deposit any cash received by it that the Company
has allocated to the Interest Reserve Amount or the provision for income taxes,
in each case in the manner contemplated by the definition of "Excess Cash"
contained herein, into a segregated cash collateral account in which the
Indenture Trustee has a perfected first priority security interest pending such
uses.

         Notwithstanding anything contained in the foregoing to the contrary,
at any time after June 15, 2000, the Company may elect to make an optional
redemption at the prices and in the manner described herein under the heading
"Optional Redemption" in lieu of making an Excess Cash Offer. In the event that
the Company makes an Optional Redemption, the Accumulated Amount shall be
reduced by an amount equal to the redemption price actually paid in connection
with such Optional Redemption.

         Additional Interest Excess Cash Offer. Upon the occurrence of a TARC
Interest Increase or a TransTexas Interest Increase the Company shall be
obligated to make an offer to purchase the Notes upon the terms and subject to

the maximum amount of Notes which could be acquired by application of the
Additional Interest Accumulated Amount as defined below (the "Additional

Interest Excess Cash Offer Price") equal to 101% of the Accreted Value of the
Senior Secured Discount Notes and the principal amount of the Senior Secured
Notes, in each case, plus accrued and unpaid interest, if any, to and including
the date the Notes tendered are purchased and paid for in accordance with the
Indenture, which date shall be no later than 25 Business Days after the first
date on which the Additional Interest Excess Cash Offer is required to be made
(the "Additional Interest Excess Cash Purchase Date"). The Company shall send
notice of an Additional Interest Excess Cash Offer at least 20 Business Days
prior to the close of business on the third Business Day prior to the
Additional Interest Excess Cash Purchase Date (the "Additional Interest Final
Put Date"), by first-class mail, to each Holder at his address set forth upon
the registry of the Company, with a copy to the Trustee. The notice to the
Holders will contain all information, instructions, and materials required by
applicable law or otherwise material to such Holders' decision to tender Notes
pursuant to the Additional Interest Excess Cash Offer. An amount equal to the
aggregate of all Additional Interest Excess Cash received by the Company is
referred to as the "Additional Interest Accumulated Amount." Prior to making
any Additional Interest Excess Cash Offer, the Company shall invest the
Additional Interest Accumulated Amount only in cash and Cash Equivalents. The
Company may, at its option, elect to make an Additional Interest Excess Cash
Offer in the manner specified herein prior to the time that the Additional
Interest Accumulated Amount exceeds $10,000,000.

         To the extent applicable and if required by law, the Company shall
comply with Section 14 of the Exchange Act and the provisions of Regulation 14E
and any other tender offer rules under the Exchange Act and other securities
laws, rules, and regulations which may then be applicable to any Additional
Interest Excess Cash Offer by the Company to purchase the Notes. The Company
shall give the Trustee prompt notice if the Additional Interest Accumulated
Amount exceeds $10,000,000.

         On or before an Additional Interest Excess Cash Purchase Date, the
Company shall (a) accept for payment Notes or portions thereof properly
tendered pursuant to the Additional Interest Excess Cash Offer prior to the
close of business on the Additional Interest Final Put Date (on a pro rata
basis between the issues (to the maximum extent possible) based on the Value of
the Notes actually tendered if Notes with a Value in excess of the Value of
Notes to be acquired are tendered and not withdrawn), (b) deposit with the
Paying Agent U.S. Legal Tender sufficient to pay the Additional Interest Excess
Cash Offer Price through the Additional Interest Excess Cash Purchase Date of
all Notes or portions thereof so accepted, and (c) deliver to the Trustee Notes

portions thereof being purchased by the Company. The Paying Agent shall
promptly mail or deliver to Holders of Notes so accepted, payment in an amount
equal to the Additional Interest Excess Cash Offer Price through the Additional
Interest Excess Cash Purchase Date for such Notes. The Trustee shall promptly
cancel all Notes accepted by the Company pursuant to the Additional Interest
Excess Cash Offer and authenticate and mail or deliver to the Holders of Notes
so accepted a new Note equal in Value to any unpurchased portion of the Note
surrendered. Any Notes not so accepted shall be promptly mailed or delivered by
the Company to the Holder thereof. The Company shall publicly announce the
results of the Additional Interest Excess Cash Offer on or as soon as
practicable after the Additional Interest Excess Cash Payment Date.

         If the amount required to acquire all Notes tendered by Holders
pursuant to the Additional Interest Excess Cash Offer (the "Additional Interest
Excess Cash Acceptance Amount") shall be less than the aggregate Additional
Interest Excess Cash Offer Amount, the excess of the Additional Interest Excess
Cash Acceptance Amount shall be (i) invested in cash or Cash Equivalents, (ii)
used by the Company to make a Note Repurchase or (iii) used by the Company to
make loans to its Subsidiaries, provided that such loans (x) are on terms no
less favorable to the Company than the economic terms described to the Holders
in the Additional Interest Excess Cash Offer, (y) are made to the parties
described in the Excess Cash Offer and (z) have a maturity date which is not
after the maturity date of the Notes. Upon consummation of any Additional
Interest Excess Cash Offer made in accordance with the terms of the Indenture,
the Additional Interest Accumulated Amount will be reduced to zero.

<PAGE>   150
         Notwithstanding anything contained in the foregoing to the contrary,
the Company shall immediately deposit any cash received by it that the Company
has allocated to the Additional Interest Reserve Amount into a segregated cash
collateral account in which the Trustee has a perfected first priority security
interest pending such uses.

         Third Party Consents. TransTexas shall use its best efforts to obtain,
as soon as reasonably practicable, all consents and approvals that may be
required under any Third Party Consent Agreement (i) for the creation,
perfection, maintenance or protection of a valid security interest in, or lien
against, any of the Collateral in favor of the Indenture Trustee or (ii) upon
foreclosure of the Indenture Trustee's lien, for the Indenture Trustee to
acquire or sell, assign, dispose of or otherwise transfer such Third Party
Consent Agreement, or any right or interest of the Company or any of its
Subsidiaries thereunder, or for the Indenture Trustee to exercise any or all of
its rights or remedies under any of the Security Documents. The use of its
"best efforts" shall not require TransTexas to pay consideration for such
consents or approvals or to take actions other than use its good faith efforts
to request such consents and approvals. TransTexas shall not, and shall not
permit any of its Subsidiaries to, permit to exist as of the end of any fiscal
quarter, any Third Party Consent Agreement if, after giving effect to such
Third Party Consent Agreement, the aggregate of all Third Party Consent
Agreements entered into after the date of the Indenture includes or relates to
properties constituting more than 25% of the net acreage owned or leased by
TransTexas or any of its Subsidiaries or Nominees after the date of the
Indenture.

         Limitation on Assets Held by Nominees. Within 270 days of the
acquisition of any Nominee Property by any Nominee (to the extent the aggregate
expenditures for all then existing Nominee Property exceeds $10 million),
TransTexas and its Subsidiaries shall cause such Nominee to assign and transfer
to TransTexas, or such of its Subsidiaries, as the case may be, all of such
Nominee's right, title and interest in and to such Nominee Property.

         Maintenance of Properties and Insurance. Each of the Company and its
Subsidiaries will cause the properties used or useful to the conduct of its
business and the business of itself and each of its Subsidiaries to be
maintained and kept in good condition, repair, and working order (reasonable
wear and tear excepted) and supplied with all necessary equipment and will
cause to be made all necessary repairs, renewals, replacements, betterments,
and improvements thereof, all as in its reasonable judgment may be necessary,
so that the business carried on in connection therewith may be properly and
advantageously conducted at all times.

         Each of the Company and its Subsidiaries will provide, or cause to be
provided, for itself and each of its Subsidiaries, insurance (including
appropriate self-insurance) against loss or damage of the kinds that, in its
reasonable, good faith opinion, are adequate and appropriate for the conduct of
its business and the business of such Subsidiaries in a prudent manner, with
reputable insurers or with the government of the United States of America or an
agency or instrumentality thereof, in such amounts, with such deductibles, and
by such methods as is customary, in its reasonable, good faith opinion, and
adequate and appropriate for the conduct of its business and the business of
its Subsidiaries in a prudent manner for companies engaged in a similar
business.

LIMITATION ON MERGER, SALE OR CONSOLIDATION

         The Indenture provides that the Company will not, and will not permit
TARC or TransTexas to, consolidate with or merge with or into any other Person
or, directly or indirectly, sell, lease, assign, transfer, or convey all or
substantially all of its assets (computed on a consolidated basis), to another
Person or group of Persons acting in concert, whether in a single transaction
or through a series of related transactions, unless (i) either (a) the Company,
TARC or TransTexas as the case may be, is the continuing Person or (b) the
resulting, surviving, or transferee entity is a corporation or partnership
organized under the laws of the United States, any state thereof, or the
District of Columbia, and shall expressly assume all of the obligations of the
Company, TARC or TransTexas, as the case may be, under the Notes, the
Intercompany Loans, the Security Documents, the Registration Rights Agreements
and the Indenture by a supplemental indenture or other appropriate document
supplemental thereto, and execute and deliver to the Indenture Trustee on or
prior to the consummation of such transaction, in form satisfactory to the
Indenture Trustee, any supplements to any Security Documents as the Indenture
Trustee, in its sole discretion, may require; (ii) no Default or Event of
Default shall exist or shall occur immediately after giving effect to such
transaction; (iii) immediately after





                                      143
<PAGE>   151
giving effect to such transaction on a pro forma basis, the Net Worth of the
surviving or transferee entity is at least equal to the Net Worth of such
predecessor or transferring entity immediately prior to such transaction; (iv)
except for a merger of TARC into a wholly owned Subsidiary of the Company or
its wholly owned Subsidiary incorporated in the State of Delaware solely for
the purpose of facilitating a reincorporation in Delaware or a repurchase of
the TARC Warrants, the surviving or transferee entity would immediately
thereafter be permitted to Incur at least $1.00 of additional Senior Debt
pursuant to the third or fourth paragraph of the covenant described herein
under the caption "Limitation on Incurrences of Additional Debt and Issuances
of Disqualified Capital Stock," as applicable (in all cases for this purpose
only, as if the Phase I Completion Date has occurred), and (v) except for a
merger of TARC into a wholly owned Subsidiary of the Company or its wholly
owned Subsidiary incorporated in the State of Delaware solely for the purpose
of facilitating a reincorporation in Delaware or a repurchase of the TARC
Warrants, at the time of or within 120 days after the occurrence of the event
specified above, the Notes have not been or are not downgraded by Standard &
Poor's Corporation, Inc., Moody's Investors Services, Inc., or any successor
rating agencies to either entity to a rating below that which existed
immediately prior to the time the event specified above is first publicly
announced. For purposes of this covenant, the Consolidated Fixed Charge
Coverage Ratio shall be determined on a pro forma consolidated basis (giving
effect to the transaction) for the four fiscal quarters immediately preceding
such transaction.

         Upon any consolidation or merger or any transfer of all or
substantially all of the assets of the Company, TARC or TransTexas in
accordance with the foregoing, the successor Person formed by such
consolidation or into which the Company, is merged or to which such transfer is
made, shall succeed to, and be substituted for, and may exercise every right
and power of, the Company, TARC or TransTexas under the Indenture, any
applicable Intercompany Loan or the Security Documents with the same effect as
if such successor corporation had been named as the Company, TARC or TransTexas
therein.

         Notwithstanding the foregoing, any Subsidiary of TARC or TransTexas
with a Net Worth greater than zero, may merge into TARC or TransTexas,
respectively (or a wholly owned Subsidiary of TARC or TransTexas, respectively)
at any time, provided, that TARC or TransTexas, as the case may be, shall have
delivered to the Indenture Trustee an Officers' Certificate stating that such
Subsidiary has a Net Worth greater than zero and such merger does not result in
a Default or an Event of Default hereunder. Notwithstanding anything contained
in the foregoing to the contrary, an Accounts Receivable Subsidiary may merge
into TARC, provided, that such merger does not result in a Default or Event of
Default hereunder.

         Notwithstanding anything contained in this covenant to the contrary,
none of TARC or TransTexas may merge into the Company or any of its
Subsidiaries.

COLLATERAL AND SECURITY

         The Notes are secured by (x) a pledge of all of the Capital Stock of
TransTexas and TARC owned by the Company and the Capital Stock of any
Subsidiaries of the Company acquired after the date hereof (the "Stock
Pledge"), which initially constituted approximately 70% of the outstanding
common stock of TransTexas and 100% of the outstanding common stock of TARC,
(y) an assignment by the Company to the Indenture Trustee, for the ratable
benefit of the holders of the Notes, of (a) the TARC Intercompany Loan, (b) the
TARC Mortgage (as defined), (c) the TransTexas Intercompany Loan and (d) the
TransTexas Mortgage (as defined) and (z) a pledge of the Company's interest in
the TEC Disbursement Account. The TARC Intercompany Loan will be secured by the
TARC Mortgage and will be guaranteed by each of the TARC Entities other than
TARC (the "TARC Entities Guarantees"). The TransTexas Intercompany Loan is
secured by the TransTexas Mortgage and will be guaranteed by each of the
TransTexas Entities other than TransTexas (the "TransTexas Entities Guarantees"
and, together with the TARC Entities Guarantees, the "Guarantees"). The TARC
Intercompany Loan, the TARC Mortgage, the TransTexas Intercompany Loan, the
TransTexas Mortgage, the Guarantees and the Stock Pledge and any ancillary
documents executed by the Company, TARC, TransTexas or their Subsidiaries or
the Indenture Trustee for purposes of providing security for the benefit of the
holders of the Notes are referred to herein as the "Security Documents"), which
encompasses a lien on (i) the Capital Stock of TARC and TransTexas owned by the
Company and any other Subsidiaries which may be acquired by the Company after
the date hereof (the "Pledged Stock"), (ii) the TARC Intercompany Loan and the
TransTexas





                                      144
<PAGE>   152
Intercompany Loan, (iii) substantially all the assets of the TARC and
substantially all of the assets of TransTexas (other than Equipment, Inventory
and Receivables and the assets used in or comprising the TTXD Related
Business), in each case, whether now owned or hereafter acquired and (iv) the
Company's interest in the TEC Disbursement Account (collectively, the
"Collateral").

         TARC has executed a recourse promissory note in the principal amount
of $920 million in favor of the Company.  TransTexas has executed a recourse
promissory note in the principal amount of $450 million in favor of the
Company.  Each of the TARC Intercompany Loan and the TransTexas Intercompany
Loan contains redemption and default terms which are substantially similar to
those of the Notes. Each Intercompany Loan will mature on June 1, 2002. The
TARC Intercompany Loan will accrete principal at 16% per annum semi-annually
until June 15, 1999. Thereafter cash interest will accrue at 16% per annum and
be payable semi-annually in arrears on June 15 and December 15 of each year
commencing on December 15, 1999. If the cost to complete Phase I is in excess
of $245 million, the interest rate borne by the TARC Intercompany Loan after
June 15, 1999 will increase from 16% to 16.25% per annum. The TransTexas
Intercompany Loan bears interest at 10 7/8% per annum payable semi-annually in
arrears on June 15 and December 15 of each year commencing on December 15,
1997. The interest rate borne on the TransTexas Intercompany Loan will increase
from 10 7/8% to 12 7/8% per annum during any TransTexas Interest Increase
Quarter. The funds received by the Company from any increase in the interest
rate payable on the TARC Intercompany Loan or the TransTexas Intercompany Loan
pursuant to the above provisions shall constitute Additional Interest Excess
Cash to be applied in accordance with the covenant described herein under the
heading " -- Additional Interest Excess Cash Offer." TARC has entered into a
mortgage (the "TARC Mortgage") which encumbers substantially all of the assets
and properties of TARC other than Equipment, Inventory and Receivables, and the
CATOFIN(R) Unit. TransTexas has also entered into a mortgage (the "TransTexas
Mortgage") which encumbers substantially all of the assets and properties of
TransTexas other than Equipment, Inventory and Receivables.

         Shares of Pledged Stock may be released from the Stock Pledge for sale
by the Company if (i) the Net Cash Proceeds of such sale are immediately
deposited in a segregated cash collateral account in which the Indenture
Trustee has a perfected first priority security interest, and (ii) funds in
such account are released only to permit the Company to fund an Excess Cash
Offer in the manner described herein under the heading "-- Excess Cash Offer."

         Notwithstanding the foregoing, no shares of Pledged Stock may be
released from the pledge pursuant to the foregoing if at the time of such
proposed release, a Default or Event of Default has occurred and is continuing
or would occur as a result of such release.

         The Company shall give written notice to the holders of Notes within
10 days of any release of Pledged Stock pursuant to the foregoing. Such notice
shall set forth the date of such release, the number of shares released, and
the provision of the Indenture pursuant to which such shares were released.

         Concurrently with any Asset Sale, the Collateral that is the subject
of such Asset Sale may be released from the security interest created by the
Security Documents.

         Upon satisfaction and discharge of the TARC Intercompany Loan, the
Indenture Trustee's lien on the TARC Collateral will be released and upon
satisfaction and discharge of the TransTexas Intercompany Loan the Indenture
Trustee's lien on the TransTexas Collateral will be released.

         Each of TARC and TransTexas will have the right, at its option, to
redeem all or a portion of the accreted value or principal amount, as the case
may be, then outstanding under the TARC Intercompany Loan or the TransTexas
Intercompany Loan, respectively, in cash at a redemption price equal to (a)
105% of the accreted value of the TARC Intercompany Loan and the principal
amount of the TransTexas Intercompany Loan for redemptions made on or prior to
December 31, 1997, (b) 108% of the accreted value of the TARC Intercompany Loan
and the principal amount of the TransTexas Intercompany Loan for redemptions
made during the period from January 1, 1998 through June 14, 2000, (c) at a
price equal to 105.750% of the accreted value of the TARC Intercompany Loan and
the principal amount of the TransTexas Intercompany Loan for redemptions made
during the period from June 15, 2000 through June 14,





                                      145
<PAGE>   153
2001 and (d) 100.000% of the accreted value of the TARC Intercompany Loan and
the principal amount of the TransTexas Intercompany Loan, for redemptions made
on or after June 15, 2001, in each case, plus accrued and unpaid interest, if
any, to and including the redemption date.

         TransTexas has secured certain supersedeas bonds and its
indemnification obligations, including pursuant to the Reimbursement and Credit
Facility, with letters of credit and escrowed cash totaling approximately $21.1
million at January 31, 1997. These parties will therefore have a claim on such
assets prior to that of the holders of the Notes.  The Indenture and the
Security Documents provide that the security interest of the Indenture Trustee
(as assignee of the Company) in the Collateral may be subordinated to First
Lien Debt. In certain circumstances, the Indenture may require the Indenture
Trustee to release Collateral with respect to First Lien Debt. In addition, the
Indenture Trustee has entered into an intercreditor and collateral agency
agreement (the "Intercreditor Agreement") with the trustees under the indenture
for the Senior TARC Mortgage Notes and the Senior TARC Discount Notes (the
"Prior TARC Notes") and Firstar Bank of Minnesota, NA, as collateral agent (the
"Collateral Agent"), that provide (i) that the TARC Intercompany Loan is
subordinated in right of payment (except regularly scheduled payments, provided
no default under the indenture governing the Prior TARC Notes exists or would
result therefrom) and lien priority to the Prior TARC Notes,  (ii) that (a) in
the event of any liquidation or reorganization of TARC any cash or other assets
paid or distributed on account of the TARC Intercompany Loan will be applied,
after payment of reasonable costs and expenses relating to obtaining such
proceeds, to the payment of the Prior TARC Notes and only after the Prior TARC
Notes have been paid in full, to the payment of the TARC Intercompany Loan and
(b) in any other event, any such proceeds will be applied so as not to impair
or affect the right of the holders of the Prior TARC Notes to receive payments
as and when due (but nothing contained in this intercreditor agreement shall be
construed to prohibit, limit or otherwise affect the rights of TARC to
transfer, dispose of or otherwise deal with its properties and assets included
within the TARC Shared Collateral securing both the Prior TARC Notes and the
TARC Intercompany Loan and the proceeds thereof, in any manner permitted under
the indenture for the Prior TARC Notes and the TARC Intercompany Loan or the
security documents relating thereto) and (iii) that determinations regarding
the exercise of remedies against the TARC Shared Collateral, as the case may
be, will be made by a majority of the outstanding principal amount of the Prior
TARC Notes and the TARC Intercompany Loan.  The principal amount of the TARC
Intercompany Loan is such that determinations under the Intercreditor Agreement
regarding enforcement of remedies and dispositions of the TARC Shared
Collateral will be controlled by the Indenture Trustee, as the holder of the
TARC Intercompany Loan, and thus, indirectly, by the holders of the Notes,
except that, and the Intercreditor Agreement so provides, nothing contained in
the Intercreditor Agreements will impair or affect the right of the holders of
any prior TARC Notes, to institute suit for the enforcement of any payment
thereon as and when due.

         If the Notes become due and payable prior to the stated maturity
thereof or are not paid in full at the stated maturity thereof, the Indenture
Trustee may take all actions it deems necessary or appropriate, including, but
not limited to, foreclosing upon the Pledged Stock in accordance with
applicable law. If such event occurs and either the TARC Intercompany Loan or
the TransTexas Intercompany Loan is due and payable prior to the stated
maturity thereof or is not paid in full at the stated maturity thereof, the
Indenture Trustee may foreclose upon the TARC Collateral or the TransTexas
Collateral, as applicable. If the Indenture Trustee takes possession of or
otherwise acquires TARC's refinery or TransTexas' natural gas reserves, the
Indenture Trustee may retain one or more experienced operators of refineries or
managers of natural gas reserves to manage the refinery or natural gas reserves
on behalf of the holders of the Notes.  The proceeds received from the sale of
any Collateral that is the subject of a foreclosure shall be applied first to
pay the expenses of such foreclosure and amounts then payable to the Indenture
Trustee and thereafter to pay (subject to any prior liens on the Collateral)
the principal of and interest on the Notes. The Indenture Trustee has the power
to institute and maintain such suits and proceedings as it may deem expedient
to prevent impairment of, or to preserve or protect its and the Holders'
interest in, the Collateral.

         Consents or approvals will be required from third parties in order to
permit the Indenture Trustee to exercise all of its rights and remedies under
the Security Documents with respect to a portion of the Collateral. Without
these consents and approvals, the Indenture Trustee may not be able to
foreclose or otherwise acquire, sell, assign or otherwise transfer, all rights
in and to this portion of the Collateral. The Indenture obligates the Company
to use its best efforts to obtain such consents and approvals and limits the
Company's ability to acquire additional Collateral subject to such





                                      146
<PAGE>   154
consent or approval requirements. However, there can be no assurance that all
such consents and approvals will be obtained.

         There can be no assurance that the Collateral Agent or the Indenture
Trustee will be able to sell the Collateral without substantial delays or that
the proceeds obtained will be sufficient to pay all amounts owing to Holders of
the Notes. See "Risk Factors -- General Risk Factors -- Adequacy of Collateral;
Risks of Foreclosure," "-- General Risk Factors -- Fraudulent Conveyance
Considerations," and "-- General Risk Factors -- Certain Bankruptcy
Considerations."

EVENTS OF DEFAULT AND REMEDIES

         The Indenture defines an Event of Default as (i) the failure by the
Company to pay installments of interest on the Notes as and when the same
become due and payable and the continuance of any such failure for 30 days,
(ii) the failure by the Company to pay all or any part of the principal or
premium, if any, on the Notes when and as the same become due and payable at
maturity, redemption, by acceleration, or otherwise, including payment of the
Excess Cash Offer Price, Additional Interest Excess Cash Offer Price or Change
of Control Purchase Price, (iii) the failure by the Company or any of its
Subsidiaries to observe or perform any other covenant, agreement, or warranty
contained in the Security Documents, the Notes or the Indenture and, subject to
certain exceptions, the continuance of such failure for a period of 30 days
after written notice is given to the Company by the Indenture Trustee or the
Company and the Indenture Trustee by the Holders of at least 25% in aggregate
Value of the Notes outstanding, (iv) certain events of bankruptcy, insolvency,
or reorganization in respect of the Company or any of its Subsidiaries, (v) a
default which extends beyond any stated period of grace applicable thereto
(including any extension thereof) under any mortgage, indenture, or instrument
under which there is outstanding any Debt of the Company or any of its
Subsidiaries aggregating in excess of $25 million or a failure to pay such Debt
at its stated maturity, provided that a waiver by all of the lenders of such
debt of such default shall constitute a waiver hereunder for the same period,
(vi) final judgments not covered by insurance aggregating at least $25 million
at any one time rendered against the Company or any of its Subsidiaries and not
stayed or discharged within 60 days, (vii) any of the Security Documents not
being in full force and effect (except where no material adverse effect to the
holders of the Notes would result) or ceasing to give the Indenture Trustee a
perfected security interest in, and Lien on, the Collateral, (viii) Independent
Directors not constituting a majority of the board of directors of the Company
for a period of 90 days in any twelve-month period, (ix) if the Phase I
Completion Date has not occurred by the Required Phase I Completion Date, or
(x) if the Phase II Completion Date has not occurred by January 31, 2000. The
Indenture provides that if a default occurs and is continuing and if it is
known to the Indenture Trustee, the Indenture Trustee must, within 90 days
after the occurrence of such default, give to the Holders notice of such
default; provided, that, except in the case of default in payment of principal
of, premium, if any, or interest on the Notes, including a default in the
payment of the Excess Cash Offer Price, Additional Interest Excess Cash Offer
Price or Change of Control Purchase Price as required by the Indenture, the
Indenture Trustee will be protected in withholding such notice if it in good
faith determines that the withholding of such notice is in the interest of the
holders of the Notes.

         If an Event of Default occurs and is continuing (other than an Event
of Default specified in clause (iv), above, relating to the Company or its
Subsidiaries), then in every such case, unless the principal of all of the
Notes shall have already become due and payable, either the Indenture Trustee
or the Holders of 25% in aggregate Value of Notes then outstanding, by notice
in writing to the Company (and to the Indenture Trustee if given by Holders)
(an "Acceleration Notice"), may declare all principal of the Notes, determined
as set forth below, and accrued interest thereon or, as appropriate, the Change
of Control Purchase Price, to be due and payable immediately. If an Event of
Default specified in clause (iv), above, relating to the Company or its
Subsidiaries occurs, all principal and accrued interest thereon will be
immediately due and payable on all outstanding Notes without any declaration or
other act on the part of the Indenture Trustee or the Holders. The Holders of
no less than a majority in aggregate Value of Notes generally are authorized to
rescind such acceleration if all existing Events of Default, other than the
non-payment of the principal of, premium, if any, and interest on the Notes
which have become due solely by such acceleration, have been cured or waived.





                                      147
<PAGE>   155
         Prior to the declaration of acceleration of the Notes, the Holders of
a majority in aggregate Value of the Notes at the time outstanding may waive on
behalf of all the Holders any default or potential default, except a default or
potential default in the payment of principal of, premium, if any, or interest
on any Note not yet cured, or a default or potential default with respect to
any covenant or provision which cannot be modified or amended without the
consent of the Holder of each outstanding Note affected. Subject to the
provisions of the Indenture relating to the duties of the Indenture Trustee,
the Indenture Trustee is under no obligation to exercise any of its rights or
powers under the Indenture at the request, order, or direction of any of the
Holders, unless such Holders have offered to the Indenture Trustee reasonable
security or indemnity. Subject to all provisions of the Indenture and
applicable law, the Holders of a majority in aggregate Value of the Notes at
the time outstanding have the right to direct the time, method, and place of
conducting any proceeding for any remedy available to the Indenture Trustee, or
exercising any trust or power conferred on the Indenture Trustee.

COVENANT DEFEASANCE; SATISFACTION AND DISCHARGE OF THE INDENTURE

         The Indenture ceases to be of further effect as to all outstanding
Notes (except as to (i) rights of registration of transfer, substitution, and
exchange of Notes and the Company's right of optional redemption, (ii) rights
of Holders to receive payments of principal of, premium, if any, and interest
on the Notes (but not the Change of Control Purchase Price of the Notes, Excess
Cash Offer Price or Additional Interest Excess Cash Offer Price) and any other
rights of the Holders with respect to such amounts, (iii) the rights,
obligations, and immunities of the Indenture Trustee under the Indenture, and
(iv) certain other specified provisions in the Indenture (the foregoing
exceptions (i) through (iv) are collectively referred to as the "Reserved
Rights")) on the 91st day (or one day after such other greater period of time
in which any such deposit of trust funds may remain subject to set aside or
avoidance under bankruptcy or insolvency laws, e.g., one year after any such
deposit) after the irrevocable deposit by the Company with the Indenture
Trustee, in trust for the benefit of the Holders, of (i) money in an amount,
(ii) U.S. Government Obligations which through the payment of interest and
principal will provide, not later than one day before the due date of payment
in respect of the Notes, money in an amount, or (iii) a combination thereof,
sufficient to pay and discharge the principal of, premium, if any, and interest
on the Notes then outstanding on the stated maturity or on the applicable
redemption date, as the case may be, and the Company must specify whether the
Notes are being defeased to maturity or to a particular redemption date. Such a
trust may be established only if certain conditions are satisfied, including
delivery by the Company to the Indenture Trustee of an opinion of outside
counsel acceptable to the Indenture Trustee (who may be outside counsel to the
Company) to the effect that (i) the defeasance and discharge will not be
deemed, or result in, a taxable event for Federal income tax purposes, with
respect to the Holders, (ii) the Company's deposit will not result in the
Company, the trust, or the Indenture Trustee being subject to regulation under
the Investment Company Act of 1940 and (iii) after the passage of 90 days (or
any greater period of time in which any such deposit of trust funds may remain
subject to bankruptcy or insolvency laws insofar as those laws apply to the
Company) following the deposit of the trust funds, such funds will not be
subject to set aside or avoidance under any bankruptcy, insolvency, or other
similar laws affecting creditors' rights generally. The Indenture will not be
discharged if, among other things, an Event of Default relating to certain
events of bankruptcy, insolvency or reorganization of the Company shall have
occurred and be continuing on the date of such deposit. The Company will be
deemed to have paid and discharged the entire indebtedness on all of the
outstanding Notes when (i) all outstanding Notes have been delivered to the
Indenture Trustee for cancellation, or (ii) the Company has paid or caused to
be paid the principal of and interest on the Notes.

REPORTS

         The Company is required to furnish to the Indenture Trustee, within 60
days after the end of each fiscal quarter or 90 days after the end of a fiscal
quarter that is also the end of a fiscal year, an officers' certificate to the
effect that such officers have conducted or supervised a review of the
activities of the Company and its Subsidiaries and of performance under the
Indenture and that, to the best of such officers' knowledge, based on their
review, the Company has fulfilled all of its obligations under the Indenture
or, if there has been a default, specifying each default known to them, its
nature and its status. The Company is also required to notify the Indenture
Trustee of any changes in the composition of the Board of Directors of the
Company or any of its Subsidiaries or of any amendment to the charter or bylaws
of the Company or any of its Subsidiaries.





                                      148
<PAGE>   156
         The Company and each of its Subsidiaries, where applicable, shall
deliver to the Indenture Trustee and to each Holder, within 15 days after it
files them with the Commission, copies of all reports and information that the
Company is required to file with the Commission pursuant to Section 13 or 15(d)
of the Exchange Act. The Company shall, or shall cause TARC to, include in all
reports required to be filed with the Commission pursuant to Section 13 or
15(d) of the Exchange Act a summary of the status of the TARC's Capital
Improvement Program, including a description of sources of funds available for
the completion of the Capital Improvement Program. The Company agrees to
continue to be subject to the filing and reporting requirements of the
Commission as long as any of the Notes are outstanding.

         Concurrently with the reports delivered pursuant to the preceding
paragraph, the Company shall deliver to the Indenture Trustee and to each
Holder annual and quarterly financial statements with appropriate footnotes of
the Company and its Subsidiaries, all prepared and presented in a manner
substantially consistent with those of the Company required by the preceding
paragraph.

AMENDMENTS AND SUPPLEMENTS

         The Indenture contains provisions permitting the Company and the
Indenture Trustee to enter into a supplemental indenture or amend the Security
Documents for certain limited purposes without the consent of the Holders. With
the consent of the Holders of not less than a majority in aggregate Value of
the Notes at the time outstanding, the Company and the Indenture Trustee are
permitted to amend or supplement the Indenture or any supplemental indenture or
modify the rights of the Holders; provided, that no such modification may,
without the consent of the Holders of not less than 66 2/3 in aggregate Value

the Change of Control Purchase Price or alter the provisions of the covenant
described herein under the heading "Repurchase of Notes at the Option of the
Holder Upon a Change of Control", (ii) prior to the date upon which an Excess
Cash Offer is required to be made, reduce the Excess Cash Offer Price or alter

covenant described herein under the heading "Additional Interest Excess Cash
Offer," in a manner adverse to the Holders; provided further, that no such
modification may, without the consent of each Holder affected thereby; (i)
change the Stated Maturity of the principal of, or any installment of principal
of, or any installment of interest on, any Note, or reduce the principal amount
thereof or the rate of interest thereon or any premium payable upon the
redemption thereof, or change the place of payment where, or the coin or
currency in which, any Note or any premium or the interest thereon is payable,
or impair the right to institute suit for the enforcement of any such payment
on or after the Stated Maturity thereof (or, in the case of redemption, on or
after the Redemption Date), or, (x) after the date upon which a Change of
Control Offer is required to be made, reduce the Change of Control Purchase
Price or alter the provisions of the covenant described herein under the
heading "Repurchase of Notes at the Option of the Holder upon a Change of
Control", (y) after the date upon which an Excess Cash Offer is required to be
made, reduce the Excess Cash Offer Price or alter the provisions of the
covenant described herein under the heading "Excess Cash" in a manner adverse
to the Holders or (z) after the date upon which an Additional Interest Excess
Cash Offer is required to be made, reduce the Additional Interest Excess Cash

the waiver provisions, except to increase any required percentage or to provide
that certain other provisions of the Indenture cannot be modified or waived
without the consent of the Holder of each Outstanding Note affected thereby.

NO PERSONAL LIABILITY OF STOCKHOLDERS, OFFICERS, DIRECTORS

         No stockholder, officer, or director, as such, past, present, or
future of the Company or any of its Subsidiaries or any successor corporation
or any of them shall have any personal liability in respect of the obligations
of the Company or such Subsidiary under the Indenture or the Notes by reason of
his or its status as such stockholder, officer, or director.

REGISTRATION RIGHTS

         The Company and the Initial Purchaser entered into the Registration
Rights Agreement pursuant to which the Company agreed to file with the
Commission promptly (but in any event on or prior to 120 days) after the
Closing Date, a registration statement on the appropriate form (the "Exchange
Offer Registration Statement"), relating to a registered exchange offer for the
Notes under the Securities Act and to use its best efforts to have such
Exchange offer Registration Statement declared effective by the Commission
within 180 days after the Closing Date.  Upon the effectiveness of the Exchange
Offer Registration Statement, the Company will offer to the holders of Notes
who are not prohibited by any law or policy of the Commission from
participating in the Exchange Offer the opportunity to exchange their
Outstanding Notes for the Exchange Notes.  In the event that applicable law or
interpretations of the staff of the Commission do not permit the Company to
effect the Exchange Offer or, in the case of any holder of Notes that
participates in the Exchange Offer, such holder does not receive freely
tradeable Exchange Notes on the date of the exchange for tendered Outstanding
Notes, or if for some reason the Exchange Offer is not consummated within 270
days after the Closing Date, or under certain circumstances upon the request of
the Initial Purchaser, the Company will, at its cost, file with the Commission
a shelf registration statement (the "Shelf Registration Statement"), to cover
resales of Outstanding Notes by the holders thereof who satisfy certain
conditions relating to the provision of information in connection with the
Shelf Registration Statement.  The Company will use its best efforts to cause
the applicable registration statement to be declared effective by the
Commission as promptly as practicable after the date of filing.

         Based on an interpretation of the staff of the Commission set forth in
several no-action letters to third parties, the Company believes that the
Exchange Notes issued pursuant to the Exchange Offer may be offered for resale,
resold and otherwise transferred by holders thereof without compliance with the
registration and prospectus delivery provisions of the Securities Act.
However, any purchaser of Notes who is an "affiliate" of the Company or who
intends to participate in the Exchange Offer for the purpose of distributing
the Exchange Notes (i) will not be able to rely on the interpretation of the
staff of the Commission set forth in the above referenced no-action letters,
(ii) will not be able to tender its Notes in the Exchange Offer and (iii) must
comply with the registration and prospectus delivery requirements of the
Securities Act in connection with any sale or transfer of the Notes unless such
sale or transfer is made pursuant to an exemption from such requirements.

         The Registration Rights Agreement provides that unless the Exchange
Offer would not be permitted by a policy of the Commission, the Company will
commence the Exchange Offer and will use its best efforts to issue, on or prior
to 30 business days after the date on which the Exchange Offer Registration
Statement is declared effective by the Commission, Exchange Notes in exchange
for all Outstanding Notes tendered prior thereto in the Exchange Offer.  Upon
the occurrence of certain Registration Defaults (as defined in the Registration
Rights Agreement), the Company will be obligated, jointly and severally, to pay
liquidated damages to each holder of Registrable Securities (as defined in the
Registration Rights Agreement), during the first 120-day period immediately
following the occurrence of such Registration Default in an amount equal to
$0.05 per week per $1,000 principal amount of Registrable Securities held by
such Holder.  Thereafter, the weekly liquidated damages amount will be $0.15
per week per $1,000 principal amount of Registrable Securities held by such
Holder, until the Registration Default is cured.  All accrued liquidated
damages will be paid in the same manner as interest payments on the Notes on
semi-annual damages payment dates that correspond to interest payment dates for
the Notes.  Following the cure of a Registration Default, the accrual of
liquidated damages will cease.

         Holders of Notes will be required to make certain representations to
the Company (as described in the Registration Rights Agreement) in order to
participate in the Exchange Offer and will be required to deliver information
to be used in connection with the Shelf Registration Statement and to provide
comments on the Shelf Registration Statement within the time periods set forth
in the Registration Rights Agreement in order to have their Notes included in
the Shelf Registration Statement.  A holder of Notes that sells such Notes
pursuant to the Shelf Registration Statement generally would be required to be
named as a selling security holder in the related prospectus and to deliver a
prospectus to purchasers, will be subject to certain of the civil liability
provisions under the Securities Act in connection with such sales and will be
bound by the provisions of the Registration Rights Agreement which are
applicable to such a holder





                                      150

(including certain indemnification obligations).  The Company will provide a
copy of the Registration Rights Agreement to prospective investors upon
request.


GLOBAL EXCHANGE NOTE; BOOK-ENTRY FORM

         The Exchange Notes initially exchanged by Qualified Institutional
Buyers (as defined in Rule 144A under the Securities Act) are represented by a
Global Exchange Note.  The Global Exchange Note will be deposited on the
Exchange Date with DTC and registered in the name of DTC or its nominee (the
"Global Exchange Note Registered Owner").  Except as set forth below, the
Global Exchange Note may be transferred, in whole and not in part, only to
another nominee of DTC or to a successor of DTC or its nominee.

         DTC is a limited-purpose trust company created to hold securities for
its participating organizations (collectively, the "Participants") and to
facilitate the clearance and settlement of transactions in those securities
between Participants through electronic book-entry changes in accounts of its
Participants.  The Participants include securities brokers and dealers, banks,
trust companies, clearing corporations and certain other organizations.  Access
to DTC's system is also available to other entities such as banks, brokers,
dealers and trust companies that clear through or maintain a custodial
relationship with a Participant, either directly or indirectly (collectively,
the "Indirect Participants").  Persons who are not Participants may
beneficially own securities held by or on behalf of DTC only through the
Participants or the Indirect Participants.  The ownership interest and transfer
of ownership interest of each actual purchaser of each security held by or on
behalf of DTC are recorded on the records of the Participants and Indirect
Participants.

         Pursuant to procedures established by DTC, (i) upon deposit of the
Global Exchange Note, DTC will credit, on its internal system, the principal
amounts of the Exchange Notes of the individual beneficial interests
represented by such Global Exchange Note to the respective accounts of
exchanging Holders who have accounts with DTC and (ii) ownership of such
interests in the Global Exchange Note will be shown on, and the transfer of
ownership thereof will be effected only through, records maintained by DTC
(with respect to the Participants) or by the Participants and the Indirect
Participants (with respect to other owners of beneficial interests in the
Global Exchange Note).  The laws of some states require that certain persons
take physical delivery in definitive form of securities that they own.
Consequently, the ability to transfer Exchange Notes will be limited to that
extent.

         Except as described below, owners of interests in the Global Exchange
Note will not have Exchange Notes registered in their names, will not receive
physical delivery of Exchange Notes in definitive form and will not be
considered the registered owners thereof under the Indenture for any purpose.

         None of the Company, the Trustee, nor any agent of the Company or the
Trustee will have any responsibility or liability for (i) any aspect of DTC's
records or any Participant's or Indirect Participant's records relating to or
payments made on account of beneficial ownership interests in the Global
Exchange Note, or for maintaining, supervising or reviewing any of DTC's
records or any Participant's or Indirect Participant's records relating to the
beneficial ownership interests in the Global Exchange Note or (ii) any other
matter relating to the actions and practices of DTC or any of its Participants
or Indirect Participants.

         Payments in respect of the principal of, premium, if any, and interest
on any Exchange Notes registered in the name of the Global Exchange Note
Registered Owner on any relevant record date will be payable by the Trustee to
the Global Exchange Note Registered Owner in its capacity as the registered
holder under the Indenture.  Under the terms of the Indenture, the Company and
the Trustee will treat the persons in whose names the Exchange Notes, including
the Global Exchange Note, are registered as the owners thereof for the purpose
of receiving such payments and for any and all other purposes whatsoever.
Consequently, neither the Company, the Trustee, nor any agent of the Company or
the Trustee has or will have any responsibility or liability for the payment of
such amounts to beneficial owners of the Exchange Notes or for any other matter
relating to actions or practices of DTC or any of its Participants or Indirect
Participants.  The Company understands that DTC's current practice, upon
receipt of any payment in respect of





                                      151
<PAGE>   159
securities such as the Exchange Notes (including principal and interest), is to
credit the accounts of the relevant Participants with the payment on the
payment date, in amounts proportionate to their respective holdings in
principal amount of beneficial interests in the relevant security as shown on
the records of DTC (unless DTC has reason to believe it will not receive
payment on such payment date).  Payments by the Participants and the Indirect
Participants to the beneficial owners of Exchange Notes will be governed by
standing instructions and customary practices and will not be the
responsibility of DTC, the Trustee or the Company.  Neither the Company nor the
Trustee will be liable for any delay by DTC or any of its Participants or
Indirect Participants in identifying the beneficial owners of the Exchange
Notes, and the Company and the Trustee may conclusively rely on and will be
protected in relying on instructions from the Global Exchange Note Registered
Owner for all purposes.

         The Global Exchange Note is exchangeable for definitive certificated
Exchange Notes if (i) DTC notifies the Company that it is unwilling or unable
to continue as depositary for the Global Exchange Note or if the Company
determines that DTC is unable to continue as depositary and the Company
thereupon fails to appoint a successor depositary, (ii) the Company, at its
option, notifies the Trustee in writing that it elects to cause the issuance of
the Exchange Notes in definitive certificated form, (iii) there shall have
occurred and be continuing an Event of Default or an event which after notice
or lapse of time would be an Event of Default with respect to the Exchange
Notes, or (iv) as provided in the last paragraph hereunder.  Such definitive
certificated Exchange Notes shall be registered in the names of the owners of
the beneficial interests in the Global Exchange Note as provided by the
Participants.  Exchange Notes in definitive certificated form will be fully
registered, without coupons, in minimum denominations of $1,000 and integral
multiples of $1,000 above the amount.  Upon issuance of Exchange Notes in
definitive certificated form, the Trustee is required to register the Exchange
Notes in the name of, and cause the Exchange Notes to be delivered to, the
person or persons (or the nominee thereof) identified as the beneficial owner
as DTC shall direct.

         Although DTC has agreed to the foregoing procedures to facilitate
transfers of interest in the Global Exchange Note among Participants of DTC, it
is under no obligation to perform or continue to perform such procedures, and
such procedures may be discontinued at any time.  Neither the Company nor the
Trustee will have any responsibility for the performance by DTC or its
Participants or Indirect Participants of their respective obligations under the
rules and procedures governing their operations.

         The information in this section concerning DTC and DTC's book-entry
system has been obtained from sources that the Company believes to be reliable,
but the Company takes no responsibility for the accuracy thereof.

         Subject to the restrictions on the transferability of the Outstanding
Notes, an Outstanding Note in definitive form will be issued upon the resale,
pledge or other transfer of any Outstanding Note or interest therein to any
person or entity that is not a Qualified Institutional Buyer or that does not
participate in DTC.  Outstanding Notes sold to Accredited Investors within the
meaning of Rule 501(a)(1), (2), (3) or (7) of Regulation D under the Securities
Act will be issued in registered, certified form without interest coupons.
Such Outstanding Notes will be subject to certain restrictions on transfer.


                              PLAN OF DISTRIBUTION

         Each broker-dealer that receives Exchange Notes for its own account
pursuant to the Exchange Offer must acknowledge that it will deliver a
Prospectus in connection with any resale of such Exchange Notes.  The
Prospectus, as it may be amended or supplemented from time to time, may be used
by a broker-dealer in connection with resales of Exchange Notes received in
exchange for Outstanding Notes where such Outstanding Notes were acquired as a
result of market-making activities or other trading activities.  The Company
has agreed that for a period not to exceed 180 days after consummation of the
Exchange Offer, it will make this Prospectus, as amended or supplemented, 
available to any broker-dealer for use in connection with any such resale.
        




                                      152
<PAGE>   160
         The Company will not receive any proceeds from any sales of the
Exchange Notes by broker-dealers.  Exchange Notes received by broker-dealers
for their own account pursuant to the Exchange Offer may be sold from time to
time in one or more transactions in the over-the-counter market, in negotiated
transactions, through the writing of options on the Exchange Notes or a
combination of such methods of resale, at market prices prevailing at the time
of resale, at prices related to such prevailing market prices or negotiated
prices.  Any such resale may be made directly to purchase or to or through
brokers or dealers who may receive compensation in the form of commissions or
concessions from any such broker-dealer and/or the purchasers of any such
Exchange Notes.  Any broker-dealer that resells the Exchange Notes that were
received by it for its own account pursuant to the Exchange Offer and any
broker or dealer that participates in a distribution of such Exchange Notes may
be deemed to be an "underwriter" within the meaning of the Securities Act, and
any profit on any such resale of Exchange Notes and any commissions or
concessions received by any such persons may be deemed to be underwriting
compensation under the Securities Act.  The Letter of Transmittal for the
Exchange Offer states that by so acknowledging and by delivering a prospectus,
a broker-dealer will not be deemed to admit that it is an "underwriter" within
the meaning of the Securities Act.

         For a period of 90 days after the Expiration Date, the Company will
promptly send additional copies of this Prospectus and any amendment or
supplement to this Prospectus to any broker-dealer that requests such documents
in the Letter of Transmittal.  The Company has agreed to pay certain expenses
incident to the Exchange Offer, other than commissions or concession of any
brokers or dealers, and will indemnify the holders of the Securities (including
any broker-dealers) against certain liabilities, including liabilities under
the Securities Act.

         By acceptance of this Exchange Offer, each broker-dealer that receives
Exchange Notes for its own account pursuant to the Exchange Offer agrees that,
upon receipt of notice from the Company of the happening of any event which
makes any statement in the Prospectus untrue in any material respect or which
request the making of any changes in the Prospectus in order to make the
statements therein not misleading (which notice the Company agrees to deliver
promptly to such broker-dealer), such broker-dealer will suspend use of the
Prospectus until the Company has amended or supplemented the Prospectus to
correct such misstatement or omission and has furnished copies of the amended
or supplemental Prospectus to such broker-dealer.  If the Company shall give
any such notice to suspend the use of the Prospectus, it shall extend the
90-day period referred to above by the number of days during the period from
and including the date of the giving of such notice to and including when
broker-dealers shall have received copies of the supplemented or amended
Prospectus necessary to permit resales of the Exchange Notes.

                                 LEGAL MATTERS

         The validity of the issuance of the Notes offered hereby will be
passed upon for the Company by Gardere & Wynne, L.L.P., Dallas, Texas.

deficit for the  two years ended July 31, 1995, the six months ended January
31, 1996 and the  year ended January 31, 1997.  These financial statements are
the responsibility of the Company's management.  Our responsibility is to

standards.  Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement.  An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements.  An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation.  We believe that our audits provide a reasonable basis
for our opinion.

    In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position
of TransAmerican Energy Corporation (and predecessor) as of  January 31, 1996
and 1997, and the results of their operations and cash flows for each of the
two years in the period ended July 31, 1995, the six months ended January 31,
1996, and the year ended January 31, 1997 in conformity with generally accepted
accounting principles.

    The accompanying consolidated financial statements have been prepared 
assuming that the Company and its wholly-owned subsidiary, TransAmerican
Refining Corporation ("TARC"), will continue as going concerns. In our prior
opinion dated May 1, 1997 we referenced uncertainty regarding TARC's ability to
amend or refinance the TARC Notes, obtain the necessary additional funds to
complete its refinery expansion and fund its ongoing working capital
requirements. As described in Note 2, in June 1997 TARC completed a tender offer
for the TARC Notes and obtained funds for its refinery expansion with proceeds
from an intercompany loan from the Company. There is no assurance that the
refinery expansion can be completed, that the funds obtained will be adequate or
that profitable operations will be ultimately achieved. As a result, there is
substantial doubt about TARC's ability to continue as a going concern.
Additionally, the Company has pledged its ownership interest in TransTexas Gas
Corporation ("TransTexas") as collateral on the Company's Senior Discount Notes,
the repayment of which is substantially dependent on TARC's ability to provide
cash flow from operations or otherwise provide funds for debt repayment. In the
event TARC does not provide adequate funds to the Company, the Company may not
be able to recover its investment in TARC and could lose its ownership interest
in TransTexas. Therefore, there is substantial doubt about the Company's ability
to continue as a going concern. The consolidated financial statements do not
include any adjustments that might result from the outcome of this uncertainty.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                (Information With Respect to the Interim Periods
                   Ended July 31, 1996 and 1997 is Unaudited)


 1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    Organization

       The consolidated financial statements include the following subsidiaries
of TransAmerican Energy Corporation (the "Company" or "TEC"), a wholly owned
subsidiary of TransAmerican Natural Gas Corporation ("TransAmerican"):

       TransTexas Gas Corporation and subsidiary and its combined predecessors
       ("TransTexas") and TransAmerican Refining Corporation ("TARC")

       For the periods prior to the formation of the Company, the combined
operations of TransTexas and TARC are referred to herein as "the predecessor."
The Company was formed on July 12, 1994 to hold 55 million shares of common
stock (74.3% of the then outstanding shares) of TransTexas and all of the
outstanding capital stock of TARC.  TransAmerican contributed 55 million shares
(74.3% of the total then outstanding) of TransTexas common stock to the Company
(the "Stock Transfer") in connection with the public offering of  TARC's senior
secured notes (the "TARC Notes").  The Company then contributed 15 million of
these shares (20.3% of the total then outstanding) of TransTexas common stock
to TARC.   In March 1996, TARC sold 4.55 million shares (6.2% of the total then
outstanding) of TransTexas common stock in public offerings.  The consolidated
financial statements include the financial statements of TransTexas and TARC on
a wholly-owned basis.  Prior to the Stock Transfer, the financial statements of
the predecessor were presented on a combined basis.

       The consolidated financial statements reflect all adjustments,
consisting of normal recurring accruals, which are, in the opinion of
management, necessary for a fair presentation of the results for the interim
periods.  Interim results of operations are not necessarily indicative of the
results that may be expected for the year ending January 31, 1998.  TransTexas
and TARC do not operate as an integrated entity.  Thus, the financial
information presented herein should be read in conjunction with the separate
financial statements of TransTexas and TARC filed on their respective Annual
Reports on Form 10-K for the fiscal year ended January 31, 1997.

       TransAmerican and certain subsidiaries emerged from a proceeding under
Chapter 11 of the Bankruptcy Code on October 19, 1987, pursuant to a confirmed
plan of reorganization.  With the proceeds of the public offering of
TransTexas' 10 1/2% senior secured notes (the "Prior Notes"), TransTexas paid
all allowed claims under TransAmerican's plan of reorganization as well as
certain other debts of TransAmerican.  During 1996, TransTexas reclassified
approximately $21.6 million of deferred tax liability to capital to properly
reflect liabilities of TransAmerican.

       TransTexas Transmission Corporation was incorporated in June 1993 as a
wholly owned subsidiary of TransTexas.  In December 1995, TransTexas
Exploration Corporation ("TTEX") was incorporated as a wholly owned subsidiary
of TransTexas and is an Unrestricted Subsidiary, as defined in the TEC Notes
Indenture (as defined in  Note 2).  TransTexas Drilling Services, Inc. was
incorporated in January 1997 as a wholly owned subsidiary of TransTexas.

       All significant intercompany transactions between the consolidated
entities have been eliminated.  All significant intercompany transactions and
balances with TransAmerican prior to the Stock Transfer are recorded in
TransAmerican's equity investment.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS   (CONTINUED)
                (Information With Respect to the Interim Periods
                   Ended July 31, 1996 and 1997 is Unaudited)


       The results of operations and cash flows for the years ended July 31,
1994, represent that of the predecessor.  Included in the results of operations
and cash flows for the year ended July 31, 1995, are the activities of the
predecessor through February 23, 1995.

    Change in Fiscal Year

       On January 30, 1996, the Board of Directors approved a change in the
Company's fiscal year end for financial reporting purposes to January 31 from
July 31.

    Management Estimates

       The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities, the
disclosure of contingent assets and liabilities at the date(s) of the financial
statements, and the reported amounts of revenues and expenses during the
reporting period(s).   Actual results could differ from these estimates.

    Cash Equivalents

       The Company considers all highly liquid investments purchased with an
original maturity of three months or less to be cash equivalents.

    Inventories

       The Company's inventories, consisting primarily of tubular goods,
refinery feedstocks and refined products, are stated at the lower of average
cost or market.  At July 31, 1995 and January 31, 1996, TARC wrote down the
value of its inventories by approximately $1.3 million and $4.4 million,
respectively,  to reflect existing market prices.

    Gas and Oil Properties

       The Company uses the full cost method of accounting for exploration and
development costs.  Under this method of accounting, the cost for successful,
as well as unsuccessful, exploration and development activities are
capitalized.  Such capitalized costs and estimated future development and
reclamation costs are amortized on a unit-of-production method.  Net
capitalized costs of gas and oil properties are limited to the lower of
unamortized cost or the cost center ceiling, defined as the sum of the present
value (10% discount rate) of estimated unescalated future net revenues from
proved reserves; plus the cost of properties not being amortized, if any; plus
the lower of cost or estimated fair value of unproved properties included in
the costs being amortized, if any; less related income tax effects.

       Proceeds from the sale of gas and oil properties are applied to reduce
the costs in the cost center unless the sale involves a significant quantity of
reserves in relation to the cost center, in which case a gain or loss is
recognized.

       Unevaluated properties and associated costs not currently being
amortized and included in gas and oil properties were $136 million, $159
million and $147 million at January 31, 1996 and 1997 and July 31, 1997,
respectively.  The properties represented by these costs were undergoing
exploration at such dates, or are properties on which the Company intends to
commence such activities in the future.  The Company believes that the
unevaluated properties at July 31, 1997 will be substantially evaluated in 12
to 24 months and it will begin to amortize these costs at such time.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS   (CONTINUED)
                (Information With Respect to the Interim Periods
                   Ended July 31, 1996 and 1997 is Unaudited)



    Refining Properties

       Property and equipment acquired subsequent to 1983, including assets
transferred from TransAmerican in 1994, are stated at TransAmerican's or TARC's
historical cost.  During the period from 1987 through August 1993, property and
equipment acquired prior to 1983 were carried at estimated net realizable value
and no depreciation expense was charged.  New or refurbished units are
depreciated as placed in service.  Depreciation of refinery equipment and other
buildings and equipment is computed by the straight-line method at rates that
will amortize the unrecovered cost of depreciable property and equipment,
including assets acquired under capital leases, over their estimated useful
lives.  Costs of improving leased property are amortized over the estimated
useful lives of the assets or the terms of the leases, whichever is shorter.

    Other Property and Equipment

       Other property and equipment are stated at cost.  The cost of repairs
and minor replacements is charged to operating expense while the cost of
renewals and betterments is capitalized.  At the time depreciable assets other
than gas and oil properties are retired, or otherwise disposed of, the cost and
related accumulated depreciation or amortization are removed from the accounts.
Gains or losses on dispositions in the ordinary course of business are included
in the consolidated statement of operations.  Impairment of other property and
equipment is reviewed whenever events or changes in circumstances indicate that
the carrying amount of assets may not be recoverable.

       Depreciation of pipeline and transmission facilities, oil field services
equipment and other buildings and equipment is computed by the straight-line
method at rates that will amortize the unrecovered cost of depreciable property
and equipment, including assets acquired under capital leases, over their
estimated useful lives.

       Costs of improving leased property are amortized over the estimated
useful lives of the assets or the terms of the leases, whichever is shorter.

    Turnarounds

       A turnaround consists of a complete shutdown, inspection and maintenance
of a unit.  The estimated costs of turnarounds are accrued over the period to
the next scheduled turnaround, which is generally greater than one year.

    Environmental Remediation Costs

       Environmental expenditures are expensed or capitalized as appropriate,
depending on their future economic benefit.  Expenditures that relate to an
existing condition caused by past operations and that do not have future
economic benefits are expensed.  Liabilities for these expenditures are
provided when the responsibility to remediate is probable and the amount of
associated cost is reasonably estimable.

    Debt Issue Costs

       Costs related to the issuance of long-term debt are classified as "Other
Assets."   Capitalized debt costs are amortized to interest expense over the
scheduled maturity of the debt utilizing the interest method.  In the event of
a redemption of long-term debt, the related debt issue costs are charged to
income in the period of redemption.

    Costs in Excess of Net Assets of Subsidiaries

       Costs in excess of net assets of subsidiaries relates to (i) the
Company's acquisition of TARC warrants of approximately $33 million and (ii)
TransTexas' purchase of its treasury stock from nonaffiliates of approximately

               TRANSAMERICAN ENERGY CORPORATION (AND PREDECESSOR)

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS   (CONTINUED)
                (Information With Respect to the Interim Periods
                   Ended July 31, 1996 and 1997 is Unaudited)


$50 million.  The Company amortizes these costs using the straight-line method
over a period of 40 years.  The Company periodically reviews the costs in
excess of net assets of subsidiaries to determine whether any impairment of
these assets has occurred.  In making such determination, the Company evaluates
the performance, on an undiscounted basis, of the underlying subsidiaries'
expected future operating cash flows in relation to the Company's net
investment in the subsidiaries.  Based on its review as of July 31, 1997, the
Company does not believe that an impairment of its costs in excess of net
assets of subsidiaries has occurred.

    Defined Contribution Plan

       The Company, through its parent company, TransAmerican, maintains a
defined contribution plan, which incorporates a "401(k) feature" as allowed
under the Internal Revenue Code.  All investments are made through
Massachusetts Mutual Life Insurance Company.  Employees who are at least 21
years of age and have completed one year of credited service are eligible to
participate on the next semiannual entry date.  The Company matches 10%, 20%,
or 50% of employee contributions up to a maximum of 3% of the participant's
compensation, based on years of plan participation.  The Company and its
predecessor's contributions with respect to this plan totaled approximately
$0.2 million, $0.3 million, $0.2 million and $0.6 million for the years ended
July 31, 1994 and 1995, the six months ended January 31, 1996 and the year ended
January 31, 1997, respectively.  All contributions are currently funded.

    Fair Value of Financial Instruments

       The Company includes fair value information in the notes to consolidated
financial statements when the fair value of its financial instruments is
different from the book value.  The Company believes the book value of those
financial instruments that are classified as current approximate fair value
because of the short maturity of these instruments.  For noncurrent financial
instruments, the Company uses quoted market prices or, to the extent that there
are no available quoted market prices, market prices for similar instruments.

    Revenue Recognition

       The Company recognizes revenues from the sales of refined products,
natural gas, condensate, oil and natural gas liquids in the period of delivery.
Revenues were recognized from transportation of natural gas in the period the
service was provided.  The sales method is used for natural gas imbalances that
arise from jointly produced properties.

    Price Management Activities

       TARC's revenues and feedstock costs have been and will continue to be
affected by changes in the prices of petroleum and petroleum products.  TARC's
ability to obtain additional capital is also substantially dependent on refined
product prices and refining margins, which are subject to significant seasonal,
cyclical and other fluctuations that are beyond TARC's control.

       From time to time, TARC enters into commonly traded refinery feedstock
and finished goods related futures contracts, options on futures, swap
agreements and forward sale agreements with the intent to protect against a
portion of the price risk associated with price declines from holding
inventory, or fixed price purchase commitments.  Commitments involving future
settlement give rise to market risk, which represents the potential loss that
can be caused by a change in the market value of a particular instrument, and
to credit risk, which represents the potential loss if a counterparty is unable
to perform.  Under the guidelines of Statement of Financial Accounting
Standards No. 80, "Accounting for Futures Contracts" ("SFAS 80"), gains and
losses associated with such transactions that meet the hedge criteria in SFAS
80 will be deferred until realized.  Those transactions that do not meet the
hedging criteria in SFAS 80 are recorded at market value resulting in a gain or
a loss that is recorded in other income in the period in which a change in
market value occurs.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS   (CONTINUED)
                (Information With Respect to the Interim Periods
                   Ended July 31, 1996 and 1997 is Unaudited)


       TransTexas' results of operations and the value of its gas and oil
properties are highly dependent upon the prices TransTexas receives for its
natural gas.  Substantially all of TransTexas' sales of natural gas are made in
the spot market, or pursuant to contracts based on spot market prices, and not
pursuant to long-term, fixed-price contracts.  Accordingly, the prices received
by TransTexas for its natural gas production are dependent upon numerous
factors beyond the control of TransTexas, including the level of consumer
product demand, the North American supply of natural gas, government
regulations and taxes, the price and availability of alternative fuels, the
level of foreign imports of oil and natural gas and the overall economic
environment.  Demand for natural gas is seasonal, with demand typically higher
during the summer and winter, and lower during the spring and fall, with
concomitant changes in price.

       From time to time, TransTexas has entered into commodity price swap
agreements (the "Hedge Agreements") to reduce its exposure to price risk in the
spot market for natural gas.  The Hedge Agreements are accounted for as hedges
if the price of the hedge agreement correlates with the price of the natural
gas production hedged.  Accordingly, gains or losses are deferred and recorded
as assets or liabilities and subsequently recognized as an increase or decrease
in revenues in the respective month the physical volumes are sold.

    Concentration of Credit Risk

       Financial instruments that potentially expose the Company to credit risk
consist principally of cash, trade receivables, commodity price swap agreements
and forward contracts.  The Company selects depository banks based upon
management's review of the financial stability of the institution.  Balances
periodically exceed the $100,000 level covered by federal deposit insurance.
To date, there have been no losses incurred due to excess deposits in any
financial institution. Trade accounts receivable are generally from companies
with significant natural gas marketing and petroleum activities, who would be
impacted by conditions or occurrences affecting those industries.  All futures
contracts have been with major brokerage firms, and in the opinion of
management, did not expose the Company to any undue credit risks.  In addition,
as of January  31, 1996, TARC had deposited cash totaling $5.1 million with two
third parties to permit the third parties to hedge their price risk in
connection with TARC's product financing arrangements.

    Income Taxes

       The Company, TARC and TransTexas file a consolidated tax return with
TransAmerican.  Income taxes  are due from or payable to TransAmerican in
accordance with a tax allocation agreement (the "Tax Allocation Agreement").
It is each company's policy to record income tax expense as though such company
had filed separately.  Deferred income taxes are recognized, at enacted tax
rates, to reflect the future effects of tax carryforwards and temporary
differences arising between the tax bases of assets and liabilities and their
financial reporting amounts in accordance with Statement of Financial
Accounting Standards No. 109 and the Tax Allocation Agreement between the
Company, TransAmerican and TransAmerican's other subsidiaries.  Income taxes
include federal and state income taxes.  The Company could not file a
consolidated return as it owns less than 80% of TransTexas and, therefore,
income taxes are presented on a combined basis.

    Recently Issued Pronouncements

       In June 1997, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards No. 131, "Disclosures about
Segments of an Enterprise and Related Information" ("SFAS 131"), which
establishes standards for reporting information about operating segments.  It
also establishes standards for related disclosures about products and services,
geographic areas and major customers.  This statement will be adopted by the
Company effective February 1, 1998.  The Company does not believe the effect of
adoption of this statement will have a material effect on its financial
position.

       In June 1997, the FASB issued Statement of Financial Accounting
Standards No. 130, "Reporting Comprehensive Income" ("SFAS 130"), which
establishes standards for reporting and display of comprehensive income and its
components in financial statements.  This statement will be adopted by the
Company effective February 1, 1998.  The Company does not believe the effect of
adoption of this statement will have a material effect on its financial
statements.

       In February 1997, the FASB issued Statement of Financial Accounting
Standards No. 128, "Earnings per Share" ("SFAS 128") and Statement of Financial
Accounting Standards No. 129, "Disclosure of Information about Capital
Structure" ("SFAS 129").  These statements will be adopted by the Company
effective January 31, 1998.  SFAS 128 simplifies the computation of earnings
per share by replacing primary and fully diluted presentations with the new
basic and diluted disclosures.  SFAS 129 establishes standards for disclosing
information about an entity's capital structure.  The Company does not believe
the effect of adoption of these statements will have a material impact on its
financial statements.

       In October 1996, the American Institute of Certified Public Accountants
issued Statement of Position 96-1, "Environmental Remediation Liabilities"
("SOP 96-1"), which establishes new accounting and reporting standards for the
recognition and disclosure of environmental remediation liabilities.  SOP 96-1
was adopted by the Company effective February 1, 1997.  The Company does not
believe the effect of adoption of SOP 96-1 will have a material impact on its
financial position, results of operations or cash flows.


 2. RECENT EVENTS

       TEC NOTES OFFERING.  On June 13, 1997, TEC completed a private offering
(the "TEC Notes Offering") of $475 million aggregate principal amount of 11
1/2% Senior Secured Notes due 2002 (the "TEC Senior Secured Notes") and $1.13
billion aggregate principal amount of 13% Senior Secured Discount Notes due
2002 (the "TEC Senior Secured Discount Notes" and, together with the TEC Senior
Secured Notes, the "TEC Notes") for net proceeds of approximately $1.3 billion.
The TEC Notes are senior obligations of TEC, secured by a lien on substantially
all its existing and future assets, including the intercompany loans described
below.  The indenture governing the TEC Notes (the "TEC Notes Indenture")
contains certain restrictive covenants, including, among others, limitations on
incurring additional debt, asset sales, dividends and transactions with
affiliates.

       The TEC Senior Secured Notes bear interest at a rate of 11 1/2% per
annum payable semi-annually in cash in arrears on June 15 and December 15 of
each year, commencing December 15, 1997.  Principal on the TEC Senior Secured
Discount Notes will accrete to 100% of the face value thereof by June 15, 1999.
Commencing December 15, 1999, cash interest on the TEC Senior Secured Discount
Notes will be payable semi-annually in arrears on June 15 and December 15 of
each year at a rate of 13% per annum.  The TEC Notes will mature on June 15,
2002.  The TEC Notes are not redeemable prior to June 15, 2000, except that the
Company may redeem, at its option, prior to June 15, 2000, up to 35% of the
original aggregate principal amount of the TEC Senior Secured Notes and up to
35% of the accreted value of the TEC Senior Secured Discount Notes, at the
redemption prices set forth in the TEC Notes Indenture, plus accrued and unpaid
interest, if any, to and including the date of redemption, with the net
proceeds of any equity offering.  On or after June 15, 2000, the TEC Notes will
be redeemable at the option of TEC, in whole or in part, at the redemption
prices set forth in the TEC Notes Indenture, plus accrued and unpaid interest,
if any, to and including the date of redemption.  Upon the occurrence of a
Change of Control (as defined), TEC will be required to make an offer to
purchase all of the outstanding TEC Notes at a price equal to 101% of the
principal amount thereof, together with accrued and unpaid interest, if any,
or, in the case of any such offer to purchase TEC Senior Secured Discount Notes
prior to June 15, 1999, at a price equal to 101% of the accreted value thereof,

case, to and including the date of purchase.  In addition, TEC will be
obligated, subject to certain conditions, to make an offer to purchase TEC
Notes with Excess Cash (as defined) at a price equal to 105% of the principal
amount of accreted value thereof, as applicable, if such purchase occurs on or
prior to December 31, 1997, at a price equal to 108% of the principal amount or
accreted value thereof, as applicable, if such purchase occurs during the
period from January 1, 1998 through June 14, 2000, and thereafter at the
redemption prices set forth in the TEC Notes Indenture in each case, together
with accrued and unpaid interest, if any, to and including the date of
purchase.

       INTERCOMPANY LOANS TO TRANSTEXAS AND TARC.  With the proceeds of the TEC
Notes Offering, TEC made intercompany loans to TransTexas in the principal
amount of $450 million  (the "TransTexas Intercompany Loan") and to TARC in the
original amount of $676 million (the "TARC Intercompany Loan" and, together
with the TransTexas Intercompany Loan, the "Intercompany Loans").  The
promissory note evidencing the TransTexas Intercompany Loan (i) bears interest
at a rate of 10 7/8% per annum, payable semi-annually in cash in arrears and
(ii) is currently secured by a security interest in substantially all of the
assets of TransTexas other than inventory, receivables and equipment.  The
promissory note evidencing the TARC Intercompany Loan (i) accretes principal at
a rate of 16% per annum, compounded semi-annually, until June 15, 1999 to a
final accreted value of $920 million, and thereafter pays interest
semi-annually in cash in arrears on the accreted value thereof, at a rate of
16% per annum and (ii) is currently secured by a security interest in
substantially all of TARC's assets other than inventory, receivables and
equipment.   The Intercompany Loan agreements contain certain restrictive
covenants, including, among others, limitations on incurring additional debt,
asset sales, dividends and transactions with affiliates.  Each Intercompany
Loan will mature on June 1, 2002.  TARC used approximately $103 million of the
proceeds of the TARC Intercompany Loan to repay certain indebtedness, including
$36 million of senior secured notes of TARC that were issued in March 1997 and
$66 million of advances and notes payable owed to an affiliate, and used
approximately $437 million to complete the TARC Notes Tender Offer (described
below).  Remaining proceeds will be used for the Capital Improvement Program
(described below) and for general corporate purposes.

       Upon the occurrence of a Change of Control (as defined in the TEC Notes
Indenture), TEC will be required to make an offer to purchase all of the
outstanding TEC Notes at a price equal to 101% of the principal amount thereof,
together with accrued and unpaid interest, if any, or, in the case of any such
offer to purchase TEC Senior Secured Discount Notes prior to June 15, 1999, at
a price equal to 101% of the accreted value thereof, in each case, to and
including the date of purchase.  Pursuant to the terms of the Intercompany
Loans, TEC may require TARC and TransTexas to pay a pro rata share of the
purchase price paid by TEC.  See "Potential Effects of a Change of Control" in
Note 18.

       TARC WARRANTS TENDER OFFER.  On June 13, 1997, TEC completed a tender
offer for the outstanding common stock purchase warrants of TARC ("TARC
Warrants") at a price of $4.50 per warrant.  Pursuant to the tender offer, TEC
purchased 7,335,452 TARC Warrants for an aggregate purchase price of
approximately $33 million.  TARC intends to enter into a merger with one of its
affiliates pursuant to which each remaining warrant, 159,861 at July 31, 1997,
would become exercisable (at an exercise price of $.01) to receive $4.51 of
cash instead of one share of common stock of TARC.

       TARC EQUITY CONTRIBUTION.  TEC intends to make a capital contribution to
TARC in the aggregate amount of $226 million from the proceeds of the
TransTexas share repurchase program (discussed below).  The amount of this
capital contribution will be retained initially in the Disbursement Account and
contributed to TARC pursuant to the terms of the Disbursement Agreement.  See
Note 4.

       DIVIDEND TO TRANSAMERICAN.  TEC paid a dividend to TransAmerican in the
amount of $23 million.  A portion of the dividend was used to repay the debt of
an affiliate, which had been secured by a pledge of 3.7 million shares of
TransTexas common stock.  In connection with the TEC Notes Offering,
TransAmerican contributed the 3.7 million shares of TransTexas common stock to
TEC.

                   Ended July 31, 1996 and 1997 is Unaudited)


       TEC PREFERRED STOCK REDEMPTION.  On June 17, 1997, TEC redeemed all of
its outstanding preferred stock for an aggregate amount of $100,000, plus
accrued and unpaid dividends.

       LOBO SALE.  On May 29, 1997, TransTexas entered into and consummated a
stock purchase agreement with an unaffiliated buyer (the "Lobo Sale
Agreement"), with an effective date of March 1, 1997, to effect the sale (the
"Lobo Sale") of the stock of TransTexas Transmission Corporation ("TTC"), its
subsidiary that owned substantially all of TransTexas' Lobo Trend producing
properties and related pipeline transmission system, for a sales price of
approximately $1.1 billion, subject to adjustments as provided for in the Lobo
Sale Agreement.  Purchase price adjustments were made for, among other things:
the value of certain NGLs and stored hydrocarbons; the value of gas in TTC's
pipeline; prepaid expenses relating to post-effective date operations;
post-closing expenses related to  pre-closing operations; the value of oil and
gas produced and sold between the effective date of the Lobo Sale Agreement and
closing (approximately $44 million); property defects; and estimated costs
associated with liabilities incurred before closing.  Purchase price
adjustments made at the closing of the Lobo Sale are subject to a review,
reconciliation and resolution process.  With proceeds from the Lobo Sale,
TransTexas repaid certain indebtedness and other obligations, including
production payments, in an aggregate amount of approximately $84 million.  The
remaining net proceeds have been or will be used for the repurchase or
redemption of the Senior Secured Notes and for general corporate purposes.

       Pursuant to the Lobo Sale, TransTexas is required to indemnify the buyer
for certain liabilities related to the assets owned by TTC.  Although
TransTexas does not anticipate that it will incur any material indemnity
liability, no assurance can be given that TransTexas will have sufficient funds
to satisfy any such indemnity obligation or that any payment thereof will not
have a material adverse effect on its ability to fund its debt service, capital
expenditure and working capital requirements.

       TRANSTEXAS SENIOR SECURED NOTES TENDER OFFER.  On June 13, 1997,
TransTexas completed a tender offer (the "TransTexas Senior Secured Notes
Tender Offer") for its 11 1/2% Senior Secured Notes due 2002 (the "TransTexas
Senior Secured Notes") for 111 1/2% of their principal amount (plus accrued and
unpaid interest).  Approximately $785.4 million principal amount of TransTexas
Senior Secured Notes were tendered and accepted by TransTexas.  The TransTexas
Senior Secured Notes remaining outstanding were called for redemption on June
30, 1997 pursuant to the terms of the indenture governing the TransTexas Senior
Secured Notes (the "TransTexas Senior Secured Notes Indenture").

       TRANSTEXAS SUBORDINATED NOTES EXCHANGE OFFER.  On June 19, 1997,
TransTexas completed an exchange offer (the "TransTexas Subordinated Notes
Exchange Offer") pursuant to which it exchanged approximately $115.8 million
aggregate principal amount of its 13 3/4% Senior Subordinated Notes due 2001
(the "TransTexas Subordinated Notes") for all of its outstanding 13 1/4% Senior
Subordinated Notes due 2003 (the "Old TransTexas Subordinated Notes").  The
indenture governing the TransTexas Subordinated Notes (the "TransTexas
Subordinated Notes Indenture") includes certain restrictive covenants,
including, among others, limitations on incurring additional debt, asset sales,
dividends and transactions with affiliates.

       As a result of the Lobo Sale, the TransTexas Senior Secured Notes Tender
Offer and the TransTexas Subordinated Notes Exchange Offer, TransTexas has
recorded a $533 million pretax gain and a $72 million after  tax  extraordinary
charge  during  the  quarter ended  July 31, 1997.

       TRANSTEXAS SHARE REPURCHASE PROGRAM.  TransTexas has implemented a share
repurchase program (the "Share Repurchase Program") pursuant to which it plans
to repurchase common stock from its public stockholders and from its
affiliates, including TEC and TARC, in an aggregate amount of approximately
$399 million in value of stock purchased.  It is anticipated that TransTexas
will acquire four times the number of shares from its affiliated stockholders
that it acquires from its public stockholders.  Shares may be purchased through
open market purchases,

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS   (CONTINUED)

                   Ended July 31, 1996 and 1997 is Unaudited)


negotiated transactions or tender offers, or a combination of the above.  It is
anticipated that the price paid to affiliated stockholders will equal the
weighted average price paid to purchase shares from the public stockholders.
As of July 31, 1997, TransTexas had repurchased 3.1 million shares of common
stock from public stockholders for an aggregate purchase price of approximately
$49.6 million.  As of September 15, 1997, approximately 0.8 million additional
shares had been purchased from public stockholders for an aggregate purchase
price of approximately $11.8 million, and approximately 12.6 million shares had
been purchased from TARC  and  TEC for  an aggregate  purchase  price  of
approximately  $201 million.

       TARC NOTES TENDER OFFER.  On June 13, 1997, TARC completed a tender
offer (the "TARC Notes Tender Offer") for its (i) Guaranteed First Mortgage
Notes due 2002 (the "TARC Mortgage Notes") for 112% of their principal amount
(plus accrued and unpaid interest), and (ii) Guaranteed First Mortgage Discount
Notes due 2002 (the "TARC Discount Notes" and, together with the TARC Mortgage
Notes, the "TARC Notes") for 112% of their accreted value.  In connection with
the TARC Notes Tender Offer, TARC obtained consents from holders of the TARC
Notes to certain waivers under, and amendments to the indenture governing the
TARC Notes (the "TARC Notes Indenture"), which eliminate or modify certain of
the covenants and other provisions contained in the TARC Notes Indenture.  TARC
Mortgage Notes and TARC Discount Notes with an aggregate carrying value of $423
million were tendered and accepted by TARC at a cost to TARC of approximately
$437 million (including accrued interest, premiums and other costs).   As a
result of the TARC Notes Tender Offer, $17.2 million in debt issuance costs
were written off and TARC recorded a total extraordinary charge of
approximately $84 million during the quarter ended July 31, 1997.  As of July
31, 1997,  TARC Mortgage Notes and TARC Discount Notes with a carrying value of
$15.7 million remained outstanding.

       GENERAL.  Following consummation of the TEC Notes Offering and the
transactions described above, TEC's only source of funds for its holding
company operations and debt service will be from payments on the Intercompany
Loans or other loans to its subsidiaries, dividends from its subsidiaries,
interest on funds in the Disbursement Account (as defined), payments made by
TARC on behalf of TEC pursuant to the Services Agreement (as defined) and, in
limited circumstances as permitted by the TEC Notes Indenture, sales of stock
TEC holds in its subsidiaries.

       During the two years following the TEC Notes Offering, TEC anticipates
that its annual cash needs for holding company operations will be approximately
$2.0 million, which TEC expects to be paid on its behalf by TARC pursuant to
the Services Agreement, and TEC's annual cash interest expense will be
approximately $54.6 million.  In addition, TEC and its subsidiaries will pay
$2.5 million in the aggregate per year to TransAmerican for advisory services
and other benefits provided by TransAmerican.  TransTexas will be required to
pay TEC approximately $48.9 million in interest annually on the TransTexas
Intercompany Loan.  TEC expects to use this interest income together with
income generated from its working capital and, to the extent necessary, its
working capital to satisfy its cash needs, including its cash interest
payments.  If TEC incurs unforeseen expenses, there is no assurance that its
capital resources will be sufficient to fund those expenses in addition to
anticipated holding company expenses and debt service.

       The TEC Notes Indenture prohibits TEC from selling stock of TransTexas
and TARC during the two years following consummation of the TEC Notes Offering
unless the proceeds from such sales would be used to make an offer to purchase
the TEC Notes.  Consequently, during the two years following the consummation of
the TEC Notes Offering, unless holders of the TEC Notes rejected all or a
portion of any such offer to purchase, sales of such stock would not be a source
of funds to supplement TEC's other resources in order to pay unforeseen
expenses.  As of July 31, 1997, the TEC Notes Indenture contained restrictions
that could substantially limit the Company's ability to use the assets of one
subsidiary to satisfy the liabilities of the other.

        TARC has incurred losses and negative cash flow from operations as a
result of limited refinery operations which did not cover the fixed costs of
maintaining the refinery, increased working capital requirements including debt
service and losses on refined product sales due to financing costs and low
margins. Based on recent refining margins and projected levels of operations,
such negative cash flows are likely to continue. If TARC does not complete the
Capital Improvement Program without significant cost overruns or does not
ultimately achieve profitable operations, TARC's investment in the refinery may
not be recovered. The financial statements do not include any adjustments as a
result of such uncertainties. Additionally, the Company has pledged its entire
ownership interest of the common stock of TransTexas as collateral on the
Company's Notes. The repayment of the notes and related interest is dependent
on TARC's ability to provide cash flow. In the event TARC does not continue as 
a going concern, it is likely that the Company will lose its entire investment 
in TransTexas. Therefore, if the Company is unable to recover its investment 
in TARC, and loses its investment in TransTexas, there is substantial doubt in
the Company's ability to continue as a going concern.

                   Ended July 31, 1996 and 1997 is Unaudited)


 3. CAPITAL IMPROVEMENT PROGRAM

       TARC's refinery is located in the Gulf Coast region along the
Mississippi River, approximately 20 miles from New Orleans, Louisiana.  TARC's
business strategy is to modify, expand and reactivate its refinery and to
maximize refining margins by converting low-cost, heavy, sour crude oils into
high-value, light petroleum products including primarily gasoline and heating
oil.

       In February 1995, TARC began a construction and expansion program
designed to reactivate the refinery and increase its complexity.  From February
1995 through April 1997, TARC spent approximately $245 million on the
construction and expansion program, procured a majority of the equipment
required and completed substantially all of the process design engineering and
a substantial portion of the remaining engineering necessary to complete this
project.

       In connection with the TEC Notes Offering, the TARC Intercompany Loan
and the TARC Notes Tender Offer, TARC has adopted a revised capital improvement
program designed to increase the capacity and complexity of the refinery
("Capital Improvement Program").  The most significant projects include: (i)
conversion of the visbreaker unit to a delayed coking unit to process vacuum
tower bottoms into lighter petroleum products, (ii) modernization and upgrade
of a fluid catalytic cracking unit to increase gasoline production capacity and
allow the direct processing of low cost atmospheric residual feedstocks and
(iii) upgrading and expanding hydrotreating, alkylation and sulfur recovery
units to increase sour crude processing capacity.  In addition, TARC plans to
expand, modify and add other processing units, tankage and offsite facilities
as part of the Capital Improvement Program.  The Capital Improvement Program
includes expenditures necessary to ensure that the refinery is in compliance
with certain existing air and water discharge regulations and that gasoline
produced will comply with federal standards.  TARC will act as general
contractor, but has engaged a number of specialty consultants and engineering
and construction  firms  to  assist  TARC  in  completing  the individual
projects  that  comprise the Capital Improvement Program.  Each of these firms
was selected because of its specialized expertise in a particular process or
unit integral to the Capital Improvement Program.

       The Capital Improvement Program will be executed in two phases.  TARC
estimates that Phase I will be completed at a cost of $223 million, will be
tested and operational by September 30, 1998 and will result in the refinery
having the capacity to process up to 200,000 BPD of sour crude oil.  Phase II
of the Capital Improvement Program includes the completion and start-up of the
Fluid Catalytic Cracking Unit utilizing state-of-the-art MSCC(SM) technology and
the installation of additional equipment expected to further improve operating
margins by allowing for a significant increase in the refinery's capacity to
produce gasoline.  TARC estimates that Phase II will be completed at a cost of
$204 million and will be tested and operational by July 31, 1999.  The proceeds
received or to be received by TARC from the TARC Intercompany Loan, the
TransTexas share repurchase program and the equity contribution from TEC will
include $427 million designated for use in the Capital Improvement Program,
which TARC believes is adequate to fund the completion of the project.  As of
July 31, 1997, TARC had spent approximately $24.1 million on the Capital
Improvement Program with commitments for another approximately $56.1 million.
The foregoing estimates, as well as other estimates and projections herein, are
subject to substantial revision upon the occurrence of future events, such as
unavailability of financing, engineering problems, work stoppages and cost
overruns over which TARC may not have any control, and there can be no
assurance that any such projections or estimates will prove accurate.

4.  DISBURSEMENT ACCOUNTS

       Pursuant to a disbursement agreement (the "Disbursement Agreement")
among TARC, TEC, the Trustee under the TEC Notes Indenture (the "TEC Indenture
Trustee"), Firstar Bank of Minnesota, as disbursement agent (the "Disbursement
Agent"), and Baker & O'Brien, Inc., as construction supervisor (the
"Construction Supervisor"), $208 million of the net proceeds from the sale of
the TEC Notes was placed into accounts in the name of TARC ($135 million) and
TEC ($73 million) (together, the "Disbursement Account") to be held and
invested by the Disbursement Agent until disbursed.  In addition, anticipated
proceeds to TEC and TARC of approximately $300 million from the TransTexas
share repurchase program have been or will be deposited in the Disbursement
Account as purchases are made.  All funds in the Disbursement Account are
pledged as security for the repayment of the TEC Notes.

       The Disbursement Agent will make disbursements for the Capital
Improvement Program out of the Disbursement Account in accordance with requests
made by TARC and approved by the Construction Supervisor.  The Construction
Supervisor is required to review each such disbursement request by TARC.  No
disbursements may be made from the Disbursement Account for purposes other than
the Capital Improvement Program other than (i) up to $1.5 million per month
(except for December 1997, in which disbursements may be up to $4.5 million) to
fund administrative costs and certain taxes and insurance payments, not in
excess of $25.5 million in the aggregate; provided, that if less than $1.5
million is spent in any month (or less than $4.5 million is spent in December
1997) the amounts that may be disbursed in one or more subsequent months will
be increased by the amount of such difference, (ii) up to $50 million for
feedstock upon certification by the Construction Supervisor of the Mechanical
Completion (as defined) of the Delayed Coking Unit and associated facilities,
(iii) up to $19 million to pay interest on,  and to redeem, repurchase, defease
or otherwise retire the remaining TARC Notes and (iv) up to $7.0 million for
outstanding accounts payable.  In addition, interest income from the
Disbursement Account may be used for the Capital Improvement Program or
disbursed to fund administrative and other costs of TARC and TEC.  As of July
31, 1997, $24.9 million had been disbursed to TARC out of the Disbursement
Account for use in the Capital Improvement Program and $7.0 million for general
corporate purposes.

       Pursuant to a disbursement agreement (the "TransTexas Disbursement
Agreement") among TransTexas, TEC, the TEC Indenture Trustee, and the Firstar
Bank of Minnesota, N.A. as disbursement agent, approximately $399 million of
the proceeds of the TransTexas Intercompany Loan was placed in an account (the
"TransTexas Disbursement Account") to be held and invested by the disbursement
agent until disbursed.  Funds in the TransTexas Disbursement Account will be
disbursed to TransTexas as needed to fund the Share Repurchase Program.
TransTexas may at any time request disbursement of interest earned on the funds
in the TransTexas Disbursement Account.  The TransTexas Disbursement Account is
classified as "cash restricted for share repurchases" in the accompanying
condensed consolidated balance sheet.  As of July 31, 1997, approximately $49.6
million had been disbursed for use in the Share Repurchase Program.

       In March 1997, TARC issued $36 million of 15% senior secured notes due
March 1998 to unaffiliated third parties.  These notes were collateralized by a
pledge of 5 million shares of TransTexas common stock.  Proceeds from the
issuance of these notes were deposited in a cash collateral account and used
for refinery construction and general corporate purposes.  These notes were
repaid  in June 1997.


5.  ADDITIONAL FINANCING AND WORKING CAPITAL REQUIREMENTS

       TARC has incurred losses and negative cash flow from operations as a
result of limited refinery operations which did not cover the fixed costs of
maintaining the refinery, increased working capital requirements including debt
service and losses on refined product sales and processing arrangements.  In
order to operate the refinery at expected levels after completion of expansion
and modification of the refinery, TARC will require additional working capital
and ultimately must achieve profitable operations.

       A primary source of funds to meet TransTexas' debt service and capital
requirements is net cash flow provided by operating activities, which is
extremely sensitive to the prices TransTexas receives for its natural gas.
TransTexas entered into Hedge Agreements to reduce its exposure to price risk
in the spot market for natural gas.  Additionally, significant capital
expenditures are required for drilling and development, lease acquisitions,
pipeline and other equipment additions.  Since July 1995, TransTexas has relied
on assets sales and various financings, in addition to cash flow from operating
activities to meet its working capital requirements, including maintenance of
Working Capital as defined in the TransTexas Indenture.  TransTexas anticipates
that it will require additional financing or sales of assets to fund planned
levels of operations through at least January 1998.

 6.  PREFERRED STOCK

       In February 1995, the Company's Board of Directors established one
series of preferred stock, designated "Series A Preferred Stock", consisting of
an aggregate of 1,000 shares.  In connection with the offering of TARC Notes,
the Company sold 1,000 shares of Preferred Stock realizing net proceeds of
$95,600.  On June 17, 1997, TEC redeemed all of its outstanding preferred stock
for an aggregate amount of $100,000, plus accrued and unpaid dividends.

       On July 2, 1996, TransTexas consummated the sale, effective as of May 1,
1996, of producing properties in Zapata County, Texas for consideration of
approximately $62 million.  On June 17 and August 13, 1996, TransTexas
consummated the sales, effective as of February 1, 1996, of certain other
producing properties in Webb County, Texas for consideration of approximately
$9.95 million and $21.5 million, respectively.  The purchase price for each of
the properties discussed above was subject to adjustment for gas sales between
the effective date and the closing date.  TransTexas retained the proceeds of
such gas sales.

       In March 1996, TransTexas sold its 41.67% interest in the 76-mile,
24-inch MidCon pipeline that runs from TransTexas' previously owned
Thompsonville compressor station to Agua Dulce for $7.5 million.

       Approximately $45 million of refinery assets were being depreciated at
January 31, 1996 and 1997, respectively.  Approximately $60 million of refinery
assets were being depreciated at July 31, 1997.   The remaining refinery and
other assets are considered construction process.  Approximately $90.4 million
of property, plant and equipment represents assets transferred by TransAmerican
at net realizable value and $553.8 million represents additions recorded at
historical cost.  As of January 31, 1997, the Company changed the estimated
useful lives of the refinery equipment currently under construction from 10
years to a range of 20 to 30 years.  The change in estimate was not material to
1997 net income.  TARC recognized $2.7 million, $5.9 million, $2.9 million,
$6.7 million and $3.2 million in depreciation expense for the years ended July
31, 1994 and 1995, the six months ended January 31, 1996, the year ended
January 31, 1997 and the six months ended July 31, 1997, respectively.

       In September 1997, TARC purchased a tank storage facility adjacent to
the refinery for a purchase price of $40 million.

       In March 1995, the FASB issued Statement of Financial Accounting
Standards No. 121, "Accounting for the Impairment of Long-Lived Assets and for
Long-Lived Assets to Be Disposed Of" ("SFAS 121").  As of February 1, 1996,
TARC adopted the requirements of SFAS 121.  TARC currently believes, based on
estimates of refining margins and current estimates for costs of the expansion
and modification program, that future undiscounted cash flows will be
sufficient to recover the cost of the refinery over its estimated useful life
as well as the costs of related identifiable intangible assets.  Management
believes there have been no events or changes in circumstances that would
require the recognition of an impairment loss.  However, due to the inherent
uncertainties in estimating future refining margins, in constructing and
operating a large scale refinery and the uncertainty regarding TARC's ability
to complete the Capital Improvement Program, there can be no assurance that
TARC will ultimately recover

the cost of the refinery.  Management believes that the book value of the
refinery is in excess of its current estimated fair market value.

      On June 20, 1995, TransTexas issued $800 million aggregate principal
amount of the TransTexas Senior Secured Notes.  TransTexas received net
proceeds of approximately $787 million from the sale of the TransTexas Senior
Secured Notes after deducting underwriting discounts, fees and expenses.
TransTexas used approximately $556 million of the net proceeds to retire or
defease the entire principal amount of the Prior Notes, including premium and
consent fees and accrued and unpaid interest, and approximately $46 million to
establish an interest reserve account.  TransTexas recorded an extraordinary
loss on the extinguishment of the Prior Notes of approximately $56.6 million.
In connection with the TransTexas Senior Secured Notes Tender Offer, TransTexas
repurchased or redeemed all of the TransTexas Senior Secured Notes.

       In December 1996, TransTexas issued $189 million in face amount of Old
TransTexas Subordinated Notes to unaffiliated third parties.  The Old
TransTexas Subordinated Notes were sold with original issue discount at a price
equal to 52.6166% of the principal amount shown on the face thereof, for gross
proceeds of approximately $99.45 million.  The Old TransTexas Subordinated
Notes accreted at a rate of 13 1/4% compounded semi-annually.  Proceeds from
the issuance of the Old TransTexas Subordinated Notes were used for working
capital and general corporate purposes.  As discussed in Note 2, in June 1997,
TransTexas exchanged approximately $115.8 million aggregate principal amount of
its TransTexas Subordinated Notes for all of its outstanding Old TransTexas
Subordinated Notes.

       On February 23, 1995, TARC issued 340,000 A Units consisting of $340
million aggregate principal amount of TARC Discount Notes and 5,811,773 of TARC
Warrants and 100,000 B Units consisting of $100 million aggregate principal
amount of TARC Mortgage Notes and 1,683,540 TARC Warrants.  TARC received
approximately $301 million from the sale of A Units and B Units.  Net proceeds
received by TARC approximated $92 million after deducting approximately $16
million for underwriting discounts, commissions, fees and expenses,
approximately $20 million for the repayment of the balance of a loan from
TransAmerican ("TransAmerican Loan"), and $173 million which was deposited into
a cash collateral account to fund the expansion and upgrading of TARC's
refinery.  As discussed in Note 2, in connection with the TARC Notes Tender
Offer, TARC Notes with an aggregate carrying value of $423 million were
tendered and accepted by TARC.  In connection with the TARC Warrants Tender
Offer, TEC purchased 7,335,452 TARC Warrants.

       In March 1997, TARC issued $36 million principal amount of 15% senior
secured notes due 1998 to unaffiliated third parties.  These notes were secured
by a pledge of the 5 million shares of TransTexas common stock.  Proceeds from
the issuance of these notes were deposited in a cash collateral account to be
used for refinery construction and general corporate purposes.  This note was
repaid in June 1997.

       TransTexas' notes payable bear interest at rates ranging from 9.25% to
12.9% per annum and mature at various dates  through  2001.   These  notes
payable  are  collateralized  by  certain  of  TransTexas'  operating
equipment.  Aggregate principal payments on TransTexas' notes payable at
January 31, 1997 total $5.2 million, $5.6 million and $0.7 million for fiscal
years ending January 31, 1998, 1999 and 2000, respectively.

       TARC's capitalized lease obligations were approximately $2.4 million and
$1.3 million at January 31, 1996 and 1997, respectively.  Maturities of such
obligations are approximately $0.8 million, $0.3 million and $0.2 million in
the years ending January 31, 1998, 1999 and 2000, respectively.

       The fair value of the TEC Notes, based on quoted market prices of
similar instruments, was approximately $1.4 billion as of July 31, 1997.  The
fair value of the TransTexas Notes, based on quoted market prices, was
approximately $818 million and $880 million as January 31, 1996 and 1997,
respectively.  The fair value of the TransTexas Subordinated Notes, based on
quoted market prices of similar instruments, was approximately $104 million as
January 31, 1997 and the fair value of the TransTexas Subordinated Exchange
Notes was approximately $131 million as of July 31, 1997.  The fair value of
the TARC Notes, based on quoted market prices, was approximately $295 million
and $404 million as January 31, 1996 and 1997, respectively.

12. CREDIT AGREEMENTS

       TransTexas and BNY Financial Corporation are parties to an Amended and
Restated Accounts Receivable Management and Security Agreement (the "BNY
Facility"), dated as of October 31, 1995 and amended in December 1996.  In
connection with the Lobo Sale, TEC Notes Offering and the transactions
described in Note 2, TransTexas and BNY entered into a waiver of the BNY
Facility, pursuant to which advances under the BNY Facility are made at the
sole discretion of the lender and the lender may require repayment of principal
and interest at any time.  Outstanding advances under the BNY Facility totaled
approximately $26.3 million and $6.2 million at January 31, 1997 and July 31,
1997, respectively.  Interest accrues on advances at the rate of (i) the
higher of (a) the prime rate of The Bank of New York or (b) the Federal Funds
Rate plus  1/2 of 1% plus (ii)  1/2 of 1%.  Obligations under the BNY Facility
are secured by liens on TransTexas' receivables and inventory.  TransTexas is
currently negotiating an amendment and restatement of the BNY Facility.

       In May 1996, TransTexas entered into a Note Purchase Agreement pursuant
to which TransTexas issued notes in the aggregate principal amount of $15.75
million, for aggregate proceeds of $15 million.  The notes, which bore interest
at 13 1/3% per annum, were paid in full in July 1996.  The notes were
guaranteed on a senior secured basis by TransAmerican.

things, increased the maximum corporate marginal federal income tax rate to 35%
from 34% effective January 1, 1993.  Deferred income taxes as of July 31, 1994
include an adjustment of approximately $2.7 million related to this increase in
corporate tax rates.  Included in "Payable to affiliates" at January 31, 1996
and 1997 are income taxes payable to TransAmerican totaling approximately $3.0
million and $14.4 million, respectively.

       During the third quarter of 1994, TARC reached a level of operations,
which, for federal income tax purposes, changed the tax status of
TransAmerican's consolidated group to an integrated oil company from an
independent producer.  As a result of this change in tax status, TransTexas was
able to utilize a greater portion of its available tight sands credits, thereby
reducing its effective tax rate for 1994.  TransTexas was unable to utilize any
tight sands credits during the six months ended January 31, 1996 or during the
year ended July 31, 1995 due to it net loss position.  Total income tax expense
differs from amounts computed by applying the statutory federal income tax rate
to income before income taxes.  The items accounting for this difference are as
follows (in thousands of dollars):

       On a separate return basis, TARC and TransTexas have a total of
approximately $379.0 million of regular tax net operating loss ("NOL")
carryforwards at July 31, 1997 which would expire from 2004 through 2013.
Under the tax allocation agreement with TransAmerican and TransAmerican's other
subsidiaries, as long as TARC and TransTexas remain in the consolidated group
for tax purposes, TARC and TransTexas will receive benefits in the future for
loss carryforwards in the form of reduced current tax payable to the extent (i)
their loss carryforwards are

ability to pay tax then due.  The Company can only use alternative minimum tax
credit carryforwards to the extent it is a regular federal income tax payer.
At July 31, 1997, TARC and TransTexas had NOL carryforwards of approximately
$203.6 million which have not been used by TransAmerican and would expire in
2013.

       TransTexas is required, under the Tax Allocation Agreement, to pay any
Texas franchise tax (which is estimated not to exceed $11.4 million)
attributable to prior year transactions.  TransTexas paid approximately $5.4
million of such tax as of the closing of the Lobo Sale and will pay a
substantial amount of the remaining tax within the ensuing 12-month period.

       TransTexas incurred approximately $69.4 million, $50.8 million, $112.9
million, $59.6 million and $56.4 million of interest charges of which
approximately $0.9 million, $7.4 million, $15.9 million, $7.5 million and $9.2
million was capitalized for the year ended July 31, 1995, the six months ended
January 31, 1996, the year ended January 31, 1997 and the six months ended July
31, 1996 and 1997, respectively, in connection with the acquisition of certain
of TransTexas' unevaluated gas and oil properties.  During 1994, TransTexas
capitalized a total of approximately $0.7 million of interest in connection
with the expansion of TransTexas' pipeline system.  TARC capitalized interest
$68.8 million for the year ended January 31, 1997 in connection with the
Capital Improvement Program.  Total interest charges incurred by TARC were
$73.5 million for the year ended January 31, 1997.


16.  TRANSACTIONS WITH AFFILIATES

       On June 13, 1997, the Transfer Agreement was amended to eliminate
TransAmerican's indemnification obligations to TransTexas other than for tax
liabilities.

       In July 1995, TransTexas acquired certain oil leases in the Lodgepole
Prospect in North Dakota from TransAmerican for approximately $6.3 million,
which amount represented TransAmerican's cost for such leases. TransTexas
continued to acquire additional leases in the area. In October 1995, TransTexas
sold an undivided interest in its Lodgepole leases to TransDakota Oil
Corporation ("TDOC"), a subsidiary of TransAmerican. The sales price was
approximately $16.1, which amount represented the cost to TransTexas of the
interest sold. In September 1996, TransTexas purchased these and other oil and
gas leasehold interests in the Lodgepole area from TDOC for approximately $20.0
million. TransTexas believes that the combination of these interests, together
with TransTexas' other interests in the Lodgepole area, will produce a more
marketable property package. The purchase price was $3.9 million greater than
TDOC's basis in the properties.  The properties have been recorded in
TransTexas' financial statements at the carryover basis and the $3.9 million
has been classified as a reduction of retained earnings.

       In June 1997, a services agreement was entered into among TransAmerican,
TransTexas, TARC and TEC.  Under the agreement, TransTexas will provide
accounting, legal administrative and other services to TARC, TEC and
TransAmerican and its affiliates.  TransAmerican will provide advisory services
to TransTexas, TARC and TEC.  TARC will pay to TransTexas approximately
$300,000 per month for services rendered to, and for allocated expenses paid by
TransTexas on behalf of TARC and TEC.  TEC and its subsidiaries will pay $2.5
million in the aggregate per year to TransAmerican for advisory services and
benefits provided by TransAmerican.  As of July 31, 1997, $0.4 million and $0.3
million was payable by TARC to TransTexas and TransAmerican, respectively,
pursuant to the services agreement.

               TRANSAMERICAN ENERGY CORPORATION (AND PREDECESSOR)

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS   (CONTINUED)
                (Information With Respect to the Interim Periods
                   Ended July 31, 1996 and 1997 is Unaudited)


       In December 1994, TransTexas entered into an interruptible gas sales
agreement with TransAmerican, revenues from which totaled approximately $14.8
million, $11.1 million, $11.7 million and $11.7 million for the six months
ended July 31, 1996, the year ended July 31, 1995, the six months ended January
31, 1996 and the year ended July 31, 1997, respectively.  The receivable from
TransAmerican for natural gas sales was paid in full in June 1997.

       TransTexas has provided accounting and legal services to TARC and TEC
and drilling and workover, administrative and procurement, accounting, legal,
lease operating, and gas marketing services to TransAmerican pursuant to a
services agreement.  TransTexas has provided general commercial legal  services
and certain accounting services (including payroll, tax, and treasury services)
to TARC and TEC for a fee of $26,000 per month.  TARC expects its general and
administrative expenses to increase significantly when the refinery commences
more complex operations.  At TransAmerican's request, TransTexas, at its
election, has provided drilling and workover services.  In June 1997, the
receivable from TransAmerican under the services agreement was paid and the
services agreement was terminated.

       In September 1995, TransTexas made advances to TransAmerican in the
aggregate amount of $4.7 million.  In October 1995, TransAmerican repaid the
full amount of these advances with interest at an annualized rate of 13%.

       In October 1995, Mr. Stanley guaranteed TransTexas' $40 million line of
credit with BNY Financial Corporation.

       As of January 1996, TransTexas and TTEX entered into a drilling program
pursuant to which TTEX received a portion of revenues, in the form of a
production payment, from certain of TransTexas' wells.  The production payment
was transferred in consideration of a note payable in the amount of $23.7
million issued by TTEX.  In July 1996, TTEX transferred this production payment
to the Company  in the form of a dividend, and TransTexas forgave the $13.2
million remaining balance of the note payable.

       In July 1996, TTEX loaned $9.5 million to TransAmerican pursuant to the
terms of a $25 million promissory note due July 31, 1998 that bore interest,
payable quarterly, at 15% per annum. TTEX made further  advances pursuant to
the note, subject to the same terms.  This note was paid in full in June 1997.

       During 1995, TransAmerican acquired an office building which it
subsequently sold to TransTexas in February 1996 for $4 million.  In February
1996, TransAmerican advanced $4 million of the proceeds from this sale to TARC
for working capital.

       In order to facilitate the settlement of certain litigation in May 1996,
TransTexas advanced to TransAmerican $16.4 million of the settlement amount in
exchange for a note receivable.  Amounts outstanding under this note were paid
in June 1997.

        In September 1996, TransTexas and TransAmerican entered into an
agreement pursuant to which TransTexas obtained an $11.5 million
dollar-denominated production payment, subsequently increased to $19 million,
bearing interest at 17% per annum, burdening certain oil and gas interests
owned by TransAmerican as a source of repayment for certain of the receivables
from TransAmerican discussed above.  On January 31, 1997, TransAmerican
conveyed, at historical cost, certain oil and gas properties to TransTexas for
a purchase price of $31.6 million.  A portion of the purchase price was used to
offset obligations under the September 1996 production payment.  At January 31,
1997, $59 million of related- party receivables were reclassified as a
reduction of stockholder's equity due to uncertainties regarding the repayment
terms for such receivables.

       TransTexas has made various advances to TransAmerican in an aggregate of
approximately $7 million for

               TRANSAMERICAN ENERGY CORPORATION (AND PREDECESSOR)

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS   (CONTINUED)
                (Information With Respect to the Interim Periods
                   Ended July 31, 1996 and 1997 is Unaudited)


lease purchases and other corporate expenses.  These advances were repaid in
June 1997.

       In January 1997, an affiliate of the Company contributed all of the
outstanding common stock of Signal Capital Holdings Corporation ("SCHC"), with
a book value of $6 million, to TransTexas.   In the same month, TransTexas
contributed the stock of SCHC to TTC.  Also in January 1997, TransTexas
contributed substantially all of its Lobo Trend properties to TTC.

       Certain refinery assets held by TransAmerican or its subsidiaries,
including the real property on which TARC's refinery is located, were
transferred to TARC in fiscal 1994 at TransAmerican's net book value of
approximately $25 million.

       In July 1994, JRS Ventures, Inc. ("JRS"), owned by John R. Stanley,
conveyed to TARC a portion of the real property on which TARC's refinery is
located. TARC paid JRS $25,000 in October 1997, which is the amount for which
JRS purchased the land in August 1993 from Lynn (as defined).

       A former affiliate of TransAmerican owed $205,000 to Lynn Petroleum
Storage and Transport Co., Inc. ("Lynn"), a company owned by Mr. Stanley's
children. This liability was assumed by TARC in conjunction with the transfer
of refinery assets described above. In May 1995, TARC paid this obligation and
an obligation arising from the purchase of a cryogenic gas processing unit and
butane tanks from Lynn at Lynn's undepreciated book value of such assets of
$492,200.  TARC believes that the purchase price for the cryogenic gas
processing unit is fair and reasonable to TARC and on terms no less favorable
than could be obtained from an unrelated third party.

       Pursuant to the stock transfer agreement (the "Stock Transfer
Agreement") among TransAmerican, the Company and TARC, TransAmerican
contributed to the capital of the Company (the "Stock Transfer") (i) all of the
outstanding capital stock of TARC, and (ii) 55 million shares of common stock
of TransTexas; and the Company then contributed 15 million of these shares of
TransTexas common stock to TARC.

       Prior to the sale of the TARC Notes, TARC participated in
TransAmerican's centralized cash management program.  Funds required by TARC
for daily operations and capital expenditures were advanced by TransAmerican.
In October 1994, TransAmerican sold 5.25 million shares of TransTexas common
stock.  TransAmerican advanced approximately $50 million of the proceeds from
these stock sales to TARC, of which approximately $20 million was used by TARC
to repay a portion of the intercompany debt owed to TransAmerican, and the
remaining $30 million of the net proceeds was used for working capital and
general corporate purposes.  TARC used approximately $30 million of the net
proceeds of the sale of the TARC Notes to repay additional intercompany debt to
TransAmerican.  TransAmerican contributed to the capital of TARC (through TEC)
all but $10 million of the remainder of TARC's intercompany debt owed to
TransAmerican.  In April 1995, TARC repaid the remaining $10 million of
intercompany indebtedness owed to TransAmerican.  In August 1995, TARC received
an advance of $3 million from TransTexas which TARC used to settle its
remaining portion of certain litigation.  In September 1995, TARC received an
advance of $1.7 million from TransAmerican which TARC used to purchase
feedstock.  In October 1995, TARC repaid these advances without interest.
Additionally in October 1995, TARC received an advance of approximately $4
million from TransAmerican for working capital which it repaid in June 1997.

       Southeast Louisiana Contractors of Norco, Inc. ("Southeast
Contractors"), a subsidiary of TransAmerican, provides construction personnel
to TARC in connection with TARC's expansion and construction program.  These
construction workers are temporary employees, and the number and composition of
the workforce will vary throughout TARC's expansion and construction program.
Southeast Contractors charges TARC for the direct costs it incurs (which
consist solely of employee payroll and benefits) plus administrative costs and
fees of up to $2.2 million per year.  Total labor costs charged by Southeast
Contractors were approximately $15.5 million, $20.2 million, $14.1 million,
$4.4 million and $9.7 million for the year ended July 31, 1995, the six months
ended

January 31, 1996, the year ended January 31, 1997 and the six months ended July
31, 1996 and 1997, respectively.  Amounts payable to Southeast Contractors were
$2.4 million at July 31, 1997.  No labor costs were charged by Southeast
Contractors in prior years.

       TransTexas sells natural gas to TARC under an interruptible long-term
sales contract.  Revenues from TARC under this contract totaled approximately
$2.3 million and $2.5 million, respectively,  for the years  ended July 31,
1994 and 1995, $2.2 million for the six months ended January 31, 1996, $2.7
million for the year ended January 31, 1997 and $1.5 million and $0.3 million,
respectively, for the six months ended July 31, 1996 and 1997.  The receivable
from TARC for natural gas sales totaled approximately $3.0 million at July 31,
1997.

       In September 1995, TARC received an advance of $1 million from
TransTexas which TARC used to purchase feedstock.  This advance was repaid by
TARC without interest.  In December 1995, TARC advanced $1 million to
TransTexas.  This advance was repaid to TARC with interest.

       In July 1996, TARC executed a promissory note to TransAmerican for up to
$25 million.  The note bore interest at a rate of 15% per annum, payable
quarterly beginning October 31, 1996, with a scheduled maturity on July 31,
1998.  As of January 31, 1997, the entire $25 million was outstanding under the
note.  On November 1, 1996, TARC executed an additional $25 million promissory
note to TransAmerican which bore interest at 15% per annum, payable quarterly
beginning December 31, 1996, with a scheduled maturity on September 30, 1998
(together with the promissory note, the "TransAmerican Notes").  At January 31,
1997, TARC had approximately $44.4 million outstanding under both of these
notes.   In February 1997, the November 1996 promissory note was replaced with
a $50 million note which bore interest at an annual rate of 15% with a
scheduled maturity on July 31, 2002. In June 1997, TARC repaid the
TransAmerican Notes.

       In July 1997, TEC advanced $5 million to TARC.  In September 1997, TEC
advanced TARC approximately $41 million.  All of the advances are governed by
the terms of a promissory note that is due June 14, 2002 bearing interest at a
rate that, when added to the interest paid by TransTexas on the TransTexas
Intercompany Loan, will equal the amount of interest payable on the TEC Notes.

       TransAmerican, its existing subsidiaries, including TARC, the Company,
and TransTexas, entered into a Tax Allocation Agreement, the general terms of
which require TransAmerican and all of its subsidiaries to file federal income
tax returns as members of a consolidated group to the extent permitted by law.
Filing on a consolidated basis allows income and tax of one member to be offset
by losses and credits of another and allows deferral of certain intercompany
gains; however, each member is severally liable for the consolidated federal
income tax liability of the consolidated group.

       The Tax Allocation Agreement requires each of TransAmerican's
subsidiaries to pay to TransAmerican each year its allocable share of the
federal income tax liabilities of the consolidated group ("Allocable Share").
The Tax Allocation Agreement provides for a reallocation of the group's
consolidated federal income tax liabilities among the members if the IRS or the
courts ultimately redetermine the group's regular tax or alternative minimum
tax liability.  In the event of an IRS audit or examination, the Tax Allocation
Agreement generally gives TransAmerican the authority to compromise or settle
disputes and to control litigation, subject to the approval of TARC, the
Company or TransTexas, as the case may be, where such compromise or settlement
affects the determination of the separate tax liability of that company.

       Under the Tax Allocation Agreement, each subsidiary's Allocable Share
for each tax year will generally equal the amount of federal income tax it
would have owed had it filed a separate federal income tax return for each year
except that each subsidiary will be able to utilize net operating losses and
credits of TransAmerican and the other members of the TransAmerican
consolidated group effectively to defer payment of tax liabilities that it
would have

otherwise owed had it filed a separate federal income tax return.  Each
subsidiary will essentially pay the deferred taxes at the time TransAmerican
(or the member whose losses or credits are utilized by such subsidiary) begins
generating taxable income or tax.  This will have the effect of deferring a
portion of such subsidiary's tax liability to future years.

       As a result of the $23 million dividend to TransAmerican described in
Note 2, the assumption of net tax liabilities of $126 million described in Note
17 and certain other transfers of assets between the Company and TransAmerican
totaling $8.0 million, additional paid-in capital increased from $158.6 million
as of January 31, 1997 to $269.6 million as of July 31, 1997.

       The TEC Notes Indenture, and previously the TARC Notes Indenture and
TransTexas Notes Indenture, requires that, with certain exceptions,
transactions between the Company and certain related parties be on terms no
less favorable to the Company than would be available from an unrelated party
and that are fair and reasonable to the Company.  This standard will apply to
future transactions, if any, with entities in which Mr. Stanley or members of
his family may have an interest.  Before the issuance of the TransTexas Notes,
TransAmerican regularly acquired products and services from suppliers owned in
whole or in part by adult children of Mr. Stanley.


17. BUSINESS SEGMENTS

       As of July 31, 1997, the Company conducts its operations through two
industry segments: exploration and production ("E&P"), and refining operations
("Refining").  Prior to the Lobo Sale, the Company also conducted operations
through its gas transportation segment ("Transportation").  The E&P segment
explores for, develops, produces and markets natural gas, condensate, crude oil
and natural gas liquids.  The Refining segment is engaged in refining and
storage operations.  The Transportation segment was engaged in intrastate
natural gas transportation and marketing. The Company's significant gas and oil
operations are located in Texas and North Dakota.  The Company's refinery is
located in Norco, Louisiana, approximately 20 miles from New Orleans,
Louisiana.  Segment income excludes interest income, interest expense and
unallocated general corporate expenses.  Identifiable assets are those assets
used in the operations of the segment.  Other assets consist primarily of
deferred financing costs, escrowed funds, certain receivables and other
property and equipment.  The Company's revenues are derived principally from
sales to interstate and intrastate gas pipelines, direct end users, industrial
companies, marketers, and refiners located in the United States.  As a general
policy,  collateral is not required  for  receivables, but  customers'
financial condition and credit worthiness are regularly evaluated.  The Company
is not aware of any significant credit risk relating to its customers and has
not experienced significant credit losses associated with such receivables.

       In 1994, one customer provided approximately $51 million in E&P and
Transportation revenues.  For the year ended July 31, 1995, two customers
provided approximately $73 million and $41 million, respectively, in E&P and
Transportation revenues.  For the Transition Period ended January 31, 1996,
three customers provided approximately $25 million, $22 million and $14
million, respectively, in E&P and Transportation revenues.  For the year ended
January 31, 1997, three customers provided approximately $70 million, $59
million and $48 million, respectively, in E&P and Transportation revenues.

       For the year ended July 31, 1994, Refining had two customers that
accounted for 46% of total revenues.  For the year ended July 31, 1995,
Refining had two customers that accounted for 56% of total revenues.  For the
six months ended January 31, 1996, Refining had three customers that accounted
for 41% of total revenues.  For the year ended January 31, 1997, Refining had
two customers that accounted for 96% of total revenues.

18.  COMMITMENTS AND CONTINGENCIES

 LEGAL PROCEEDINGS

       As part of the Transfer, TransTexas succeeded to the potential
liability, if any, of TransAmerican and certain subsidiaries in connection with
the lawsuits described below.  TransTexas assumed liability for litigation up
to $15 million plus the difference, if any, between $10 million and the costs
(if less than $10 million) incurred to resolve the disputed claims.  Pursuant
to an agreement among TransTexas, TransAmerican and certain of its
subsidiaries, as amended (the "Transfer Agreement"), TransAmerican agreed to
indemnify TransTexas against all losses incurred by TransTexas in excess of $25
million in connection with (a) disputed claims in TransAmerican's bankruptcy
and (b) other litigation assumed by TransTexas and other agreements related to
TransAmerican's  plan of reorganization (other than settlements and judgments
paid from escrowed cash established in connection with TransAmerican's plan of
reorganization).  On June 13, 1997, the Transfer Agreement was amended to
eliminate TransAmerican's indemnity obligations to TransTexas other than for
tax liabilities.

       ALAMEDA.  On May 22, 1993, Alameda Corporation ("Alameda") sued
TransAmerican in the 234th Judicial District Court, Harris County, Texas,
claiming that TransAmerican failed to account to Alameda  for a share of the
proceeds TransAmerican received in a 1990 settlement of litigation with El Paso
Natural Gas  Company  ("El Paso"),  and that TransAmerican has been unjustly
enriched by its failure to share such proceeds with Alameda. On September 20,
1995, the jury rendered a verdict in favor of TransAmerican.  Alameda appealed
to the Fourteenth Court of Appeals, which affirmed the trial court judgment in
favor of TransAmerican.  Alameda filed a motion for rehearing on April 10, 1997
and TransAmerican responded.  The court denied Alameda's motion,  and Alameda
has appealed to the Texas Supreme Court.

       ASPEN.  TransAmerican brought suit on September 29, 1993 against Aspen
Services, Inc. ("Aspen"), seeking an audit and accounting of drilling costs
that Aspen had charged while providing drilling services to TransAmerican.
This suit is pending in the 215th Judicial District Court, Harris County,
Texas.  The parties' drilling agreement provided, among other things, that
Aspen would receive payment for its drilling-related costs from the production
and sale of gas from the wells that were drilled, and that the revenues that
TransAmerican would otherwise receive from the wells would be reduced by the
amounts received by Aspen.  On July 19, 1995, Aspen filed a counterclaim and
third party claim against TransAmerican, TransTexas, and affiliated entities,
asserting, among other things, that these entities failed to make certain
payments and properly market the gas from these wells.   Aspen sought damages
in an unspecified amount, as well as certain equitable claims.  In April 1997,
the trial court ruled against Aspen on all of its claims and counterclaims.

       BRIONES.  In an arbitration proceeding, Jesus Briones, a lessor, claimed
that one of TransTexas' wells on adjacent lands had been draining natural gas
from a portion of his acreage leased to TransTexas on which no well had been
drilled.  On October 31, 1995, the arbitrator decided that drainage had
occurred.  On June 3, 1996, the arbitrator issued a letter indicating that
drainage damages would be awarded to Briones in the amount of approximately
$1.4 million.  The arbitrator entered his award of damages on June 27, 1996.
On July 3, 1996, TransTexas filed a petition in the 49th Judicial District
Court, Zapata County, Texas, to vacate the arbitrator's award.  Briones also
filed a petition to confirm the arbitrator's award.  In April 1997, the court
granted Briones' motion for summary judgment.  In August 1997, the court
entered a final judgment for Briones in the amount of approximately $1.6
million.  TransTexas intends to file a motion for new trial.

       FINKELSTEIN.   On  April  15,  1990,  H.S. Finkelstein filed suit
against TransAmerican in the 49th Judicial District Court, Zapata County,
Texas, alleging that TransAmerican failed to pay royalties and improperly
marketed oil and gas produced from certain leases.  On September 27, 1994, the
plaintiff added TransTexas as an additional defendant.  On January 6, 1995, a
judgment against TransAmerican and TransTexas was entered for approximately $18
million in damages, interest and attorneys' fees.  TransTexas and TransAmerican
appealed the judgment to the Fourth Court of Appeals, San Antonio, Texas, which
affirmed the judgment on April 3, 1996.  TransTexas and TransAmerican filed a
motion for rehearing.  On August 14, 1996, the Fourth Court of Appeals reversed
the trial court judgment and rendered judgment in favor of TransAmerican and
TransTexas.  On August 29, 1996, Finkelstein filed a motion for stay and a
motion for rehearing with the court.  On October 9, 1996, the court denied
Finkelstein's rehearing request.  In November 1996, Finkelstein filed an
application for writ of error with the Supreme Court of Texas.

       On April 22, 1991, Finkelstein filed a separate suit against
TransAmerican and various affiliates in the 49th Judicial District Court,
Zapata County, Texas, alleging an improper calculation of overriding royalties
allegedly owed to the plaintiff and seeking damages and attorneys' fees in
excess of $33.7 million.   On November 18, 1993, the plaintiff added TransTexas
as an additional defendant.  The parties arbitrated this matter in January
1997.  A partial decision from the arbitration panel has been rendered in favor
of Finkelstein.  Although the amount of damages has yet to be determined under
the panel's decision, such amount will be substantially less than that sought
by plaintiff.

       ARABIAN OFFSHORE PARTNERS.  On June 27, 1997, Arabian Offshore Partners
filed a lawsuit against TransTexas in the 14th Judicial District Court, Dallas
County, Texas, seeking $20 million in damages in connection with TransTexas'
refusal to proceed with the acquisition of two jack-up drilling rigs.
TransTexas has filed its answer and is preparing a motion for summary judgment.

       EEOC.  On August 31, 1995, the U.S. Equal Employment Opportunity
Commission ("EEOC") issued a Commissioner's Charge against TARC and Southeast
Louisiana Contractors of Norco, Inc. (the "Commissioners Charge") pursuant to
Sections 706 and 707 of Title VII of the Civil Rights Act of 1964, as amended,
42 U.S.C. Section  2000e et seq. ("Title VII").  In the Commissioner's Charge,
the EEOC charged TARC and Southeast Louisiana Contractors of Norco, Inc.
("Southeast Contractors"), a subsidiary of TransAmerican, with engaging in
unlawful discriminatory hiring and promotion practices based on race and
gender.  Each violation of Title VII, if proven, potentially could subject TARC
and/or Southeast Contractors to liability for (i) monetary damages for back pay
and/or front pay in an undetermined amount, and for compensatory damages and/or
punitive damages in an amount that should not exceed $300,000, (ii) injunctive
relief, (iii) attorney's fees, and/or (iv) interest.  During the period covered
by the Commissioner's Charge, TARC and Southeast Contractors estimate that they
received a combined total of approximately 15,000 to 22,000 employment
applications and hired (or rehired) a combined total of approximately 1,500 to
2,200 workers.  TARC and Southeast Contractors have responded to the
Commissioner's Charge and have denied engaging in any unlawful employment
practices.  TARC and Southeast Contractors have been cooperating fully with the
EEOC in connection with its investigation.  TARC and Southeast Contractors
intend to vigorously defend against the allegations contained in the
Commissioner's Charge in all proceedings before the EEOC and in any subsequent
litigation.  If TARC and/or Southeast Contractors are found liable for
violations of Title VII based on the matters asserted in the Commissioner's
Charge, TARC can make no assurance that such liability would not have a
material adverse effect on the financial condition, results of operations and
cash flows of TARC or TARC's ability to pay interest or principal on its debt.

       RINEHEART.  On October 8, 1996, Carlton Gene Rineheart, et al., and as
representative of a class of persons similarly situated, filed suit against 84
individuals and corporations, including TARC, in the U.S. District Court,
Middle District of Louisiana alleging negligent and improper storage, handling,
treatment, and disposal of hazardous materials from 1976 to the present at two
sites in Iberville Parish, Louisiana.  The suit claims damages for physical,
mental, and property damage in the communities of Bayou Sorrel, Bayou Pigeon
and Indian Village.  TARC intends to vigorously defend this claim.

       SHELL OIL.  On September 27, 1996, Shell Oil filed a third party suit
against TARC in the U.S. District Court, Eastern District of Louisiana for
contribution and/or indemnity relating to alleged environmental contamination
of Bayou Trapagnier and surrounding lands near Norco, Louisiana.    In March
1997, TARC obtained a voluntary dismissal from Shell.  Shell proceeded to trial
on the main case and settled with the plaintiffs during trial by purchasing
their land for $5 million.  On June 27, 1997, Shell amended its third party
action to bring TARC back into the case.  Shell has demanded $400,000 from
TARC.  TARC has refused to pay such amount and is defending the case
vigorously.

       GENERAL.  TransTexas and TARC are also named defendants in other
ordinary course, routine litigation incidental to their businesses.  While the
outcome of these other lawsuits cannot be predicted with certainty, the Company
does not expect these matters to have a material adverse effect on its
financial position.  At July 31, 1997, the possible range of estimated losses
related to all of the aforementioned claims in addition to the estimates
accrued by TransTexas and TARC is $0 to $36 million.  The resolution in any
reporting period of one or more of these matters in a manner adverse to TARC or
TransTexas could have a material adverse impact on the Company's results of
operations or cash flows for that period.

                   Ended July 31, 1996 and 1997 is Unaudited)


    ENVIRONMENTAL MATTERS

       TransTexas' operations and properties are subject to extensive federal,
state, and local laws and regulations relating to the generation, storage,
handling, emission, transportation, and discharge of materials into the
environment.  Permits are required for various of TransTexas' operations, and
these permits are subject to revocation, modification, and renewal by issuing
authorities.  TransTexas also is subject to federal, state, and local laws and
regulations that impose liability for the cleanup or remediation of property
which has been contaminated by the discharge or release of hazardous materials
or wastes into the environment.  Governmental authorities have the power to
enforce compliance with their regulations, and violations are subject to fines
or injunctions, or both.  It is not anticipated that TransTexas will be
required in the near future to expend amounts that are material to the
financial condition or operations of TransTexas by reason of environmental laws
and regulations, but because such laws and regulations are frequently changed
and, as a result, may impose increasingly strict requirements, TransTexas is
unable to predict the ultimate cost of complying with such laws and
regulations.

       COMPLIANCE MATTERS.  TARC is subject to federal, state, and local laws,
regulations, and ordinances  ("Pollution Control Laws"), which regulate
activities such as discharges to air and water, as well as handling and
disposal practices for solid and hazardous wastes.  TARC believes that it is in
substantial compliance with applicable Pollution Control Laws.  However, newly
enacted Pollution Control Laws, as well as increasingly strict enforcement of
existing Pollution Control Laws, will require TARC to  make  capital
expenditures in  order  to  comply with  such laws  and regulations.  To
ensure  continuing compliance, TARC has made environmental compliance and
permitting issues an integral part of its refinery's start-up plans and has
budgeted for such capital expenditures in the Capital Improvement Program.

       TARC uses (and in the past has used) certain materials, and generates
(and in the past has generated) certain substances or wastes, that are or may
be deemed hazardous substances or wastes.  In the past, the refinery has been
the subject of certain environmental enforcement actions, and has incurred
certain fines, as a result of certain of TARC's operations.  TARC also was
previously subject to enforcement proceedings relating to its prior production
of leaded gasoline and air emissions.  TARC believes that, with minor
exception, all of these past matters were resolved prior to or in connection
with the resolution of the bankruptcy proceedings of its predecessor in
interest, TransAmerican, or are no longer applicable to TARC's operations.  As
a result, TARC believes that such matters will not have a material adverse
effect on TARC's future results of operations, cash flow or financial position.

       REQUIREMENTS UNDER THE FEDERAL CLEAN AIR ACT.  The National Emission
Standards for Hazardous Air Pollutants for Benzene Waste Operations (the
"Benzene Waste NESHAPS"), promulgated in January 1993 pursuant to the Clean Air
Act, regulate benzene emissions from numerous industries, including petroleum
refineries.  The Benzene Waste NESHAPS require all existing, new, modified, or
reconstructed sources to reduce benzene emissions to a level that will provide
an ample margin of safety to protect public health.  TARC will be required to
comply with the Benzene Waste NESHAPS as its refinery operations start up.  At
this time, TARC cannot estimate the costs of such compliance.  TARC believes
that compliance with the Benzene Waste NESHAPS will not have a material adverse
effect on its financial position, results of operations or cash flow.  Until
the refinery is in full operation, however, there can be no assurance that the
regulations will not have such an effect.

       In addition, the Environmental Protection Agency ("EPA") promulgated
National Emission Standards for Hazardous Air Pollutants for Hazardous Organics
(the "Hazardous Organics NESHAPS") regulations for petroleum refineries under
the Clean Air Act in 1995, and subsequently has amended such regulations.
These regulations set "Maximum Achievable Control Technology ("MACT") standards
for petroleum refineries.  The Louisiana Department of Environmental Quality
(the "LDEQ") has incorporated MACT standards into TARC's air permits under
federal and state air pollution prevention laws.  TARC believes that compliance
with the Hazardous Organics NESHAPS will not have a material adverse effect on
TARC's financial position, results of operations or cash flow.

               TRANSAMERICAN ENERGY CORPORATION (AND PREDECESSOR)

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS   (CONTINUED)
                (Information With Respect to the Interim Periods
                   Ended July 31, 1996 and 1997 is Unaudited)


Until the refinery is in full operation, however, there can be no assurance
that the regulations will not have such an effect.

       The EPA recently promulgated federal regulations pursuant to the Clean
Air Act to control fuels and fuel additives (the "Gasoline Standards") that
could have a material adverse effect on TARC.  Under the new regulations, only
reformulated gasoline can be sold in certain domestic geographic areas in which
the EPA has mandated or approved its use.  Reformulated gasoline must contain a
minimum amount of oxygen, have a lower vapor pressure, and have reduced sulfur,
olefins, benzene and aromatics compared to the average 1990 gasoline.  The
number and extent of the areas subject to reformulated gasoline standards may
increase in the future if the EPA's National Ambient Air Quality Standards
("NAAQS") proposals for particulate matter and ozone are implemented.
Conventional gasoline may be used in all other domestic markets; however, a
refiner's post-1994 average conventional gasoline must not be more polluting
than it was in 1990.  With limited exceptions, to determine its compliance as
of January 1, 1995, a refiner must compare its post-1994 and 1990 average
values of controlled fuel parameters and emissions.  The Gasoline Standards
recognize that many gasoline refiners may not be able to develop an individual
1990 baseline for a number of reasons, including, for example, lack of adequate
data or the absence or limited scope of operations in 1990.  Under such
circumstances, the refiner must use a statutory baseline reflecting the 1990
industry average.  The EPA has authority, upon a showing of extenuating
circumstances by a refiner, to grant an individual adjusted baseline or other
appropriate regulatory relief to that refiner.

       TARC filed a petition with the EPA requesting an individual baseline
adjustment or other appropriate regulatory relief based on extenuating
circumstances.  The extenuating circumstances upon which TARC relied in its
petition include the fact that the refinery was not in operation in 1990 (and
thus there is no 1990 average for purposes of the necessary comparison) and the
fact that the start-up of the refinery is to occur on a phased-in basis.  The
EPA has denied TARC's request for an individual baseline adjustment and other
appropriate regulatory relief.  TARC will continue to pursue regulatory relief
with the EPA.  There can be no assurance that any action taken by the EPA will
not have a material adverse effect on TARC's future results of operations, cash
flows or financial position.

       Title V of the Clean Air Act requires states to implement an Operating
Permit Program that codifies all federally enforceable limitations that are
applicable to a particular source.  The EPA has approved Louisiana's Title V
Operating Permit Program.  The deadline for a refinery to submit an Operating
Permit Application under the Louisiana program was October 12, 1996.  TARC
timely submitted its Title V Operating Permit application and the LDEQ has
designated the application as being administratively complete.  As yet, the
LDEQ has not responded further regarding the status of TARC's Title V Operating
Permit.  TARC believes that its application will be approved.  However, there
can be no assurance that additional expenditures required pursuant to Title V
Operating Permit obligations will not have a material adverse effect on TARC's
financial position, results of operations or cash flow.

       CLEANUP MATTERS.  TARC also is subject to federal, state, and local
laws, regulations, and ordinances that impose liability for the costs of clean
up relating to, and certain damages resulting from, past spills, disposals, or
other releases of hazardous substances ("Hazardous Substance Cleanup Laws").
Over the past several years, TARC has been, and to a limited extent continues
to be, engaged in environmental cleanup or remedial work relating to or arising
out of operations or activities at the refinery.  In addition, TARC has been
engaged in upgrading its solid waste facilities, including the closure of
several waste management units.  Similar to numerous other industrial sites in
the state, the refinery has been listed by the LDEQ on the Federal
Comprehensive Environmental Response, Compensation and Liability Information
System, as a result of TARC's prior waste management activities (as discussed
below).

       In 1991, the EPA performed a  facility assessment at TARC's refinery
pursuant to the Federal Resource Conservation and Recovery Act ("RCRA"). The
EPA performed a follow up assessment in March 1996, but has not yet  issued a
report of its investigations.  In July 1996, the EPA and LDEQ agreed that the
LDEQ would serve as the

               TRANSAMERICAN ENERGY CORPORATION (AND PREDECESSOR)

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS   (CONTINUED)
                (Information With Respect to the Interim Periods
                   Ended July 31, 1996 and 1997 is Unaudited)


lead agency with respect to the investigation and remediation of areas of
concern identified in the investigation.  TARC, under a voluntary initiative
approved by the LDEQ, has submitted a work plan to the LDEQ to determine which
areas may require further investigation and remediation.  The LDEQ has not yet
responded to TARC's submission or issued any further requests relating to this
matter.  As a result, TARC is unable at this time to estimate what the costs,
if any, will be if the LDEQ does require further investigation or remediation
of the areas identified.

       TARC has been identified as a potentially responsible party ("PRP")
under the Comprehensive Environmental Response, Compensation, and Liability Act
of 1980, as amended ("CERCLA" or "Superfund"), for the cleanup of contamination
from hazardous substances at three Superfund sites (i.e. sites on the National
Priorities List ("NPL")) to which it has been alleged that TARC, or its
predecessors, sent hazardous substances in the past.  CERCLA requires cleanup
of sites from which there has been a "release" or threatened release of
"hazardous substances" (as such terms are defined under CERCLA).  CERCLA
requires the EPA to include sites needing long-term study and cleanup on the
NPL based on their potential effect on public health or the environment.
CERCLA authorizes the EPA to take any necessary response actions at NPL sites
and, in certain circumstances, to order PRPs liable for the release to take
such actions.  PRPs are broadly defined under CERCLA to include past and
present owners and operators of a site, as well as generators and transporters
of wastes to a site from which hazardous substances are released.

       The EPA may seek reimbursement of expenditures of federal funds from
PRPs under Superfund.  Courts have interpreted CERCLA to impose strict, joint
and several liability upon all persons liable for the entire amount of
necessary cleanup costs.  As a practical matter, at sites where there are
multiple PRPs for a cleanup, the costs of cleanup typically are allocated
according to a volumetric or other standard among the parties.  CERCLA also
provides that responsible parties generally may recover a portion of the costs
of cleaning up a site from other responsible parties.  Thus, if one party is
required to clean up an entire site, that party can seek contribution or
recovery of such costs from other responsible parties.  A number of states have
laws similar to Superfund, pursuant to which cleanup obligations, or the costs
thereof, also may be imposed.

       At one Superfund site, TARC has submitted information to the EPA
indicating that it should have no liability for this matter, and negotiations
are continuing.  With respect to the remaining two sites, TARC's liability for
each such matter has not been determined, and TARC anticipates that it may
incur costs related to the cleanup (and possibly including additional costs
arising in connection with any recovery action brought pursuant to such
matters) at each such site.  After a review of the data available to TARC
regarding the basis of TARC's alleged liability at each site, and based on
various factors, which depend on the circumstances of the particular Superfund
site (including, for example, the relationship of TARC to each such site, the
volume of wastes TARC is alleged to have contributed to each such site in
comparison to other PRPs without giving effect to the ability of any other PRPs
to contribute to or pay for any liabilities incurred, and the range of likely
cleanup costs at each such site), TARC does not believe its ultimate
environmental liabilities will be significant; however, it is not possible to
determine the ultimate environmental liabilities, if any, that may arise from
the matters discussed above.

    POTENTIAL EFFECTS OF A CHANGE OF CONTROL

       The Subordinated Notes Indenture provides that, upon the occurrence of a
Change of Control, each holder of the TransTexas Subordinated Exchange Notes
will have the right to require TransTexas to repurchase such holder's notes at
101% of the principal amount thereof plus accrued and unpaid interest.
Pursuant to the terms of the TransTexas Intercompany Loan, upon the occurrence
of a Change of Control, TEC would have the right to require TransTexas and TARC
to repay the principal of the TransTexas Intercompany Loan in an amount equal
to a pro rata share of the amount TEC is required to pay under the TEC Notes
Indenture.  Such pro rata share would be calculated using the ratio of the
outstanding principal amount of the TransTexas Intercompany Loan (or, for TARC,
the accreted value of the outstanding principal amount of the TARC Intercompany
Loan) to the sum of (i) the outstanding principal amount of the TransTexas
Intercompany Loan plus (ii) the accreted value of the outstanding principal
amount of the

TARC Intercompany Loan.  A Change of Control would be deemed to occur under the
Subordinated Notes Indenture in the case of certain changes or other events in
respect of the ownership of TransTexas, including any circumstances pursuant to
which any person or group other than John R. Stanley and his subsidiaries or
the TEC Indenture Trustee is or becomes the beneficial owner of more than 50%
of the total voting power of TransTexas' then outstanding voting stock and
during the 90-day period thereafter the rating on the notes is downgraded or
withdrawn.  A Change of Control would be deemed to occur under the TEC Notes
Indenture, the TransTexas Intercompany Loan and the TARC Intercompany Loan in
the case of certain changes or other events in respect of the ownership or
control of TEC, TransTexas, or TARC including any circumstance pursuant to
which (i) any person or group, other than John R. Stanley and  his
subsidiaries or the TEC Indenture Trustee is or becomes the beneficial owner of
more than 50% of the total voting power of TEC's then outstanding voting stock,
or (iii) TEC or any of its subsidiaries own some of TransTexas' or TARC's
capital stock, respectively, but less than 50% of the total voting stock or
economic value of TransTexas or TARC, respectively, unless the TEC Notes have
an investment grade rating for the period of 120 days thereafter.  The term
"person," as used in the definition of Change of Control, means a natural
person, company, government or political subdivision, agency or instrumentality
of a government and also includes a "group," which is defined as two or more
persons acting as a partnership, limited partnership or other group.  In
addition, certain changes or other events in respect of the ownership or
control of TransTexas that do not constitute a Change of Control under the
Subordinated Notes Indenture or the TEC Notes Indenture may result in a "change
of control" of TransTexas under the terms of TransTexas' credit facility (the
"BNY Facility") and certain equipment financing.  Such an occurrence could
create an obligation for TransTexas to repay such other indebtedness.  At July
31, 1997, TransTexas had approximately $26.6 million of indebtedness (excluding
the Senior Secured Notes and the TransTexas Subordinated Exchange Notes)
subject to such right of repayment or repurchase.  In the event of a Change of
Control under the TEC Notes Indenture or a "change of control" under the terms
of other outstanding indebtedness, there can be no assurance that TransTexas or
TARC will have sufficient funds to satisfy any such payment obligations.

       A change of control or other event that results in deconsolidation of
TransTexas and TransAmerican for federal income tax purposes could result in
acceleration of a substantial amount of federal income taxes.  These matters,
individually and in the aggregate, amount to significant potential liability
which, if adjudicated in a manner adverse to TransTexas in one reporting
period, could have a material adverse effect on TransTexas' cash flow or
operations for that period.  Although the outcome of these contingencies or the
probability of the occurrence of these contingencies cannot be predicted with
certainty, TransTexas does not expect these matters to have a material adverse
effect on its financial position.

    PURCHASE COMMITMENTS

       TARC has various purchase commitments for materials, supplies and
services incidental to the ordinary course of business and for the Capital
Improvement Program.   As of July 31, 1997, TARC had commitments for refinery
construction and maintenance of approximately $56 million.  TARC is acting as
general contractor and can generally cancel or postpone capital projects.

       In September 1997, TARC acquired a tank storage facility adjacent to the
refinery for a purchase price of $40 million.

    LETTER OF CREDIT

       In January 1996, TransTexas entered into a reimbursement agreement with
an unaffiliated third party pursuant to which the third party caused a $20
million letter of credit to be issued to collateralize a supersedeas bond on
behalf of TransTexas.  If there is a draw under the letter of credit,
TransTexas is required to reimburse the third party within

60 days.  TransTexas has agreed to issue up to 8.6 million shares of its common
stock to the third party if this contingent obligation to such third party
becomes fixed and remains unpaid for 60 days.  TransTexas does not believe that
this contingency will occur.  If the obligation becomes fixed, and alternative
sources of capital are not available, TransTexas could elect to sell shares of
TransTexas common stock prior to the maturity of the obligation and use the
proceeds of such sale to repay the third party.  Based on TransTexas' current
capitalization, the issuance of shares of TransTexas' common stock to satisfy
this obligation would result in deconsolidation of TransTexas for federal
income tax purposes.

    PRODUCTION PAYMENTS

       On February 28, 1995, TransTexas sold to an unaffiliated third party a
term royalty in the form of a dollar- denominated production payment in certain
of TransTexas' properties for proceeds of $49.5 million, less closing costs of
approximately $2 million.  This production payment was paid in full in May 1996
with a portion of the proceeds of the volumetric production payment described
below.

       In January 1996, TransTexas sold to an unaffiliated third party a term
overriding royalty interest in the form of a volumetric production payment
carved out of its interests in certain of its producing properties.  For net
proceeds of approximately $33 million, TransTexas conveyed to the third party a
term overriding royalty equivalent to a base volume of approximately 29 Bcf of
natural gas, subject to certain increases in the base volume and in the
percentage interest dedicated if certain minimum performance and delivery
requirements are not met. In February 1996, in consideration for additional net
proceeds of approximately $16 million, TransTexas supplemented the production
payment to subject a percentage of its interests in certain additional
producing properties to the production payment and to include additional
volumes of approximately 14 Bcf of natural gas within the base volume subject
to the production payment.  At January 31, 1997, approximately 23 Bcf of
natural gas remained subject to this production payment.  In May 1996,
TransTexas sold to two unaffiliated third parties a volumetric production
payment for net proceeds of approximately $43 million.  TransTexas conveyed to
the third parties a term overriding royalty equivalent to a base volume of
approximately 37 Bcf of natural gas, subject to certain increases in the base
volume and in the percentage interest dedicated if certain minimum performance
and delivery requirements are not met. Concurrently with the closing of that
transaction, TransTexas and one of the unaffiliated third parties terminated,
prior to the expiration of its stated term, a dollar-denominated term
overriding royalty interest previously sold by TransTexas to that unaffiliated
third party for a payment by TransTexas of approximately $25 million.  As a
result of such termination, the remaining base volume from the previously sold
overriding royalty interest was conveyed to TransTexas.  In connection with the
Lobo Sale, volumes remaining to be delivered under these production payments
were settled for payments by TransTexas of approximately $68 million.

       In September 1996, TransTexas sold to an unaffiliated third party a term
royalty in the form of a dollar- denominated production payment in certain of
TransTexas' properties for proceeds of $13.5 million.  The production payment
called for the repayment of the primary sum plus an amount equivalent to a 16%
annual interest rate on the unpaid portion of such primary sum.   In connection
with the Lobo Sale, this production payment was paid in full.

       In September 1996, TransTexas entered into a drilling program agreement
with an unaffiliated third party for the reimbursement of certain drilling
costs with respect to wells drilled by TransTexas.  Pursuant to the agreement,
upon the approval of the third party of a well for inclusion in the program,
the third party committed to the reimbursement of all or a portion of the cost
of such well, up to an aggregate maximum for all such wells of $16.5 million.
The program wells were subject to a dollar-denominated production payment equal
to the principal amount of such reimbursed costs, plus an amount equivalent to
a 17.5% annual interest rate on the unpaid portion of such principal amount.
In April 1997, this production was paid in full.

                   Ended July 31, 1996 and 1997 is Unaudited)


       In April 1997, TransTexas sold to an unaffiliated third party a term
overriding royalty in the form of a  dollar- denominated production payment in
certain of TransTexas' producing properties for net proceeds of $20 million.
The production payment calls for the repayment of the primary sum plus an
amount equivalent to a 16% annual interest rate on the unpaid portion of such
primary sum.

    POTENTIAL TAX LIABILITY

       Part of the refinancing of TransAmerican's debt in 1993 involved the
cancellation of approximately $65.9 million of accrued interest and of a
contingent liability for interest of $102 million owed by TransAmerican.
TransAmerican has taken the federal tax position that the entire amount of this
debt cancellation is excluded from its income under the cancellation of
indebtedness provisions  (the "COD Exclusion") of the Internal Revenue Code of
1986, as amended, and has reduced its tax attributes (including its net
operating loss and credit carryforwards) as a consequence of the COD Exclusion.
No federal tax opinion was rendered with respect to this transaction, however,
and TransAmerican has not obtained a ruling from the Internal Revenue Service
(the "IRS") regarding this transaction.  TransTexas believes that there is
substantial legal authority to support the position that the COD Exclusion
applies to the cancellation of TransAmerican's indebtedness.   However, due to
factual and legal uncertainties, there can be no assurance that the IRS will
not challenge this position, or that such challenge would not be upheld. Under
an agreement between TransTexas, TransAmerican and certain of TransAmerican's
subsidiaries (the "Tax Allocation Agreement"), TransTexas has agreed to pay an
amount equal to any federal tax liability (which would be approximately $25.4
million) attributable to the inapplicability of the COD Exclusion.  Any such
tax would be offset in future years by alternative minimum tax credits and
retained loss and credit carryforwards to the extent recoverable from
TransAmerican.  As a member of the TNGC Consolidated Group (defined below),
each of TransTexas, TEC and TARC will be severally liable for any tax liability
resulting from the above-described transactions.  The IRS has commenced an
audit of the consolidated federal income tax returns of the TNGC Consolidated
Group for its taxable years ended July 31, 1994 and 1995.  Because the audit is
in its initial stages, it is not possible to predict the scope of the IRS'
review or whether any tax deficiencies will be proposed by the IRS as a result
of its review.

       Based upon independent legal advice, TransTexas has determined that it
will not report any significant federal income tax liability as a result of the
Lobo Sale.  There are, however, significant uncertainties regarding TransTexas'
tax position and no assurance can be given that TransTexas' position will be
sustained if challenged by the IRS.  TransTexas is part of an affiliated group
for tax purposes (the "TNGC Consolidated Group"), which includes TNGC Holdings
Corporation, the sole stockholder of TransAmerican.  No letter ruling has been
or will be obtained from the IRS regarding the Lobo Sale by any member of the
TNGC Consolidated Group.  If the IRS were to successfully challenge TransTexas'
position, each member of the TNGC Consolidated Group would be severally liable
under the consolidated tax return regulations for the resulting taxes, in the
estimated amount of up to $250 million (assuming the use of existing tax
attributes of the TNGC Consolidated Group), possible penalties equal to 20% of
the amount of the tax, and interest at the statutory rate (currently 9%) on the
tax and penalties (if any).  The Tax Allocation Agreement has been amended so
that TransAmerican will become obligated to fund the entire tax deficiency (if
any) resulting from the Lobo Sale.  There can be no assurance that
TransAmerican would be able to fund any such payment at the time due and the
other members of the TNGC Consolidated Group, thus, may be required to pay the
tax.  TransTexas has reserved approximately $75 million with respect to the
potential tax liability for financial reporting purposes to reflect a portion
of the federal tax liability that TransAmerican might not be able to pay.  If
TransTexas

were required to pay this tax deficiency, it  is  likely  that  it  would  be
required to sell significant assets or raise additional debt or equity capital
to fund the payment.

       Under certain circumstances, TransAmerican, the Company or TARC may sell
or otherwise dispose of shares of common  stock  of  the  Company.   If, as a
result of any sale or other disposition  of  the  Company's  common stock, the
aggregate ownership of TransTexas by members of the TNGC Consolidated Group
(excluding TransTexas) is less than 80% (measured by voting power and value),
TransTexas will no longer be a member of the TNGC Consolidated Group for
federal tax purposes ("Deconsolidation") and, with certain exceptions, will no
longer be obligated under the terms and conditions of, or entitled to the
benefits of, the Tax Allocation Agreement.   Further, if the Company or TARC
sells or otherwise transfers any stock of TARC, or issues any options, warrants
or  other similar rights relating to such stock, outside of the TNGC
Consolidated Group, which represents more than 20% of the voting power or
equity value of TARC, then a Deconsolidation of TARC  would occur.   A
Deconsolidation of TARC would result in a Deconsolidation of TransTexas if the
TNGC Consolidated Group, excluding TARC, does not then own at least 80% of the
voting power and equity value of TransTexas.  Upon a Deconsolidation of
TransTexas, members of the TNGC Consolidated Group that own TransTexas' common
stock could incur a substantial amount of federal income tax liability.  If
such Deconsolidation occurred during the fiscal year ending January 31, 1998,
the aggregate amount of this tax liability is estimated to be between $50
million and $100 million, assuming no reduction for tax attributes of the TNGC
Consolidated Group.  However, such tax liability generally would be
substantially reduced or eliminated in the event that the IRS successfully
challenged TransTexas' position on the Lobo Sale.  Each member of a
consolidated group filing a consolidated federal income tax return is severally
liable to the IRS for the consolidated federal income tax liability of the
consolidated group.  There can be no assurance that each TNGC Consolidated
Group member will have the ability to satisfy any tax obligation attributable
to the Transactions at the time due and, therefore, other members of the group,
including the Company, TransTexas or TARC, may be required to pay the tax.

       TransTexas has significant contingent liabilities, including liabilities
with respect to litigation matters and other obligations assumed in the
Transfer.  In addition, a change of control or other event that results in
deconsolidation of TransTexas and TransAmerican for federal income tax purposes
could result in acceleration of a substantial amount of federal income taxes.
These matters, individually and in the aggregate, amount to significant
potential liability which, if adjudicated in a manner adverse to TransTexas in
one reporting period, could have a material adverse effect on TransTexas' cash
flow or operations for that period.  Although the outcome of these
contingencies or the probability of the occurrence of these contingencies
cannot be predicted with certainty, TransTexas does not expect these matters to
have a material adverse effect on its financial position.

    PRICE MANAGEMENT ACTIVITIES

       TARC enters into futures contracts, options on futures, swap agreements,
and forward sale agreements with the intent to protect against a portion of the
price risk associated with price declines from holding inventory of feedstocks
and refined products or fixed price purchase commitments.   At January 31,
1997, TARC's position in open futures contracts, options on futures, and swap
agreements was not significant.  A net trading gain of approximately $3.1
million and a trading loss of approximately $2.3 million were reflected in
other income (expense) for the years ended July 31, 1994 and 1995,
respectively.  These transactions do not qualify for hedge accounting treatment
under the guidelines of SFAS 80; therefore, gains or losses associated with
these futures contracts are recognized currently in other income.

    FINANCING ARRANGEMENTS AND PROCESSING AGREEMENTS

       TARC enters into financing arrangements in order to maintain an
available supply of feedstocks.  Typically, TARC enters into an agreement with
a third party to acquire a cargo of feedstock which is scheduled for delivery
to

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS   (CONTINUED)

                   Ended July 31, 1996 and 1997 is Unaudited)


TARC's refinery.  TARC pays through the third party all transportation costs,
related taxes and duties and letter of credit fees for the cargo, plus a
negotiated commission.  Prior to arrival at the refinery, another third party
purchases the cargo, and TARC commits to purchase, at a later date, the cargo
at an agreed price plus commission and costs.  TARC also places margin deposits
with the third party to permit the third party to hedge its price risk.  TARC
purchases these cargos in quantities sufficient to maintain expected operations
and is obligated to purchase all of the cargos delivered pursuant to these
arrangements.  In the event the refinery is not operating, these cargos may be
sold on the spot market.  During the year ended January 31, 1997, approximately
1.1 million barrels of feedstocks with a cost of $23 million were sold by a
third party on the spot market prior to delivery to TARC without a material
gain or loss to TARC.

       In March 1996, TARC entered into a processing agreement with a third
party for the processing of various feedstocks at the refinery.  Under the
terms of the agreement, the processing fee earned by TARC is based on the
margin earned by the third party, if any, after deducting all of its related
costs such as feedstock acquisition, hedging, transportation, processing and
inspections plus a commission for each barrel processed.  For the year ended
January 31, 1997, TARC processed approximately 1.1 million barrels of feedstock
pursuant to this agreement.  TARC incurred a loss of approximately $2.6 million
related to this processing agreement primarily as a result of low margins and
price management activities.

       In April 1996, TARC entered into a similar processing agreement with
another third party to process feedstocks.  As of July 31, 1997, TARC had
processed approximately 6.4 million barrels of feedstocks under this agreement.
TARC also entered into a processing agreement with this third party to process
approximately 0.6 million barrels of the third party's feedstocks for a fixed
price per barrel.  Under the terms of this fixed price agreement, TARC met all
quantity and quality yields earning the full price per barrel.  For the year
ended January 31, 1997, TARC recorded a net loss of approximately $4.5 million
related to these processing arrangements primarily as a result of low margins
and price management activities. As of January 31, 1997 and July 31, 1997, TARC
was storing approximately 1.0 million and 0.8 million barrels, respectively, of
feedstock and intermediate or refined products.  For the six months ended July
31, 1996 and 1997, TARC recorded income (loss) from processing agreements of
$(3.3) million and $3.2 million, respectively.  Included in the 0.8 million
barrels of product stored at the refinery as of July 31, 1997, is approximately
0.6 million barrels of feedstock related to a purchase commitment entered into
in April 1997.  The 0.6 million barrels have been sold to the third party
involved in the processing arrangement.  For the six months ended July 31,
1997, TARC incurred a loss of approximately $4.8 million related to this
purchase commitment.

       TARC also entered into processing agreements with this third party to
process approximately 1.1 million barrels of the third party's feedstocks for a
fixed price per barrel.  As of July 31, 1997, TARC recorded a net margin of
approximately $0.2 million related to these processing arrangements, primarily
as a result of income on the fixed fee processing agreement.

    HEDGING AGREEMENTS

       Beginning in April 1995, TransTexas entered into Hedge Agreements to
reduce its exposure to price risk in the spot market for natural gas.  Pursuant
to the Hedge Agreements, either TransTexas or the counterparty thereto was
required to make a payment to the other at the end of each month (the
"Settlement Date").  The payments equaled the product of a notional quantity
("Base Quantity") of natural gas and the difference between a specified fixed
price ("Fixed Price") and a market price ("Floating Price") for natural gas.
The Floating Price was determined by reference to natural gas futures contracts
traded on the New York Mercantile Exchange ("NYMEX").  The Hedge Agreements
provided for TransTexas to make payments to the counterparty to the extent that
the Floating Price exceeded the Fixed Price, up to a maximum ("Maximum Floating
Price") and for the counterparty to make payments to TransTexas to the extent
that the Floating Price was less than the Fixed Price.   For the year ended

January 31, 1997, TransTexas made net settlement payments totaling
approximately $37 million to the counterparty pursuant to the Hedge Agreements.
As of January 31, 1997, TransTexas had Hedge Agreements with Settlement Dates
ranging from February 1997 through April 1997 involving total Base Quantities
aggregating approximately 20.4 TBtu of natural gas.   Fixed Prices for these
agreements ranged from $1.70 to $1.78 per MMBtu ($1.76 to $1.84 per Mcf) up to
Maximum Floating Prices ranging from $2.00 to $2.20 per MMBtu ($2.07 to $2.28
per Mcf).  In addition, one agreement had a Fixed Price of $2.48 per MMBtu
($2.57 per Mcf) with no Maximum Floating Price.  Under the terms of this
agreement, the counterparty advanced $5 million to TransTexas.  For the six
months ended July 31, 1997, TransTexas incurred net settlement losses pursuant
to the Hedge Agreements of approximately $7.4 million.  As of July 31, 1997,
TransTexas had no Hedge Agreements outstanding.

    OPERATING LEASES

       As of July 31, 1997, the Company has long-term leases covering land and
other property and equipment.  Rental expense was approximately $7 million and
$9 million for the years ended July 31, 1994 and 1995, respectively, $5 million
for the six months ended January 31, 1996, $10 million for the year ended
January 31, 1997 and $5 million for the six months ended July 31, 1997.  Future
minimum rental payments required under operating leases that have initial or
remaining noncancellable lease terms in excess of one year as of January 31,
1997, including the sale-leaseback transaction described below, are as follows
(in thousands of dollars):

18.  LITIGATION SETTLEMENTS

       BENTSEN.  On August 13, 1990, Calvin R. Bentsen, et al. filed suit
against TransAmerican and Mr. Stanley in the 139th Judicial District Court,
Hidalgo County, Texas, seeking a portion of the El Paso settlement proceeds,
and an accounting of monies allegedly owed to them, claiming that TransAmerican
produced gas that belonged to them without their knowledge and that
TransAmerican entered into an oral agreement with them which entitled them to
receive a portion of the El Paso settlement proceeds.  This case was settled in
April 1997.

       COASTAL.  On October 28, 1991, The Coastal Corporation ("Coastal") filed
an action against TransAmerican that was consolidated in the 49th Judicial
District Court, Webb County, Texas, alleging breach of contract and tortious
interference related to two gas sales contracts and a transportation agreement,
seeking unspecified actual and punitive damages and injunctive relief.  On
April 22, 1994, the court entered a judgment adverse to TransAmerican and
TransTexas requiring them to pay $1.3 million plus $0.7 million in attorneys'
fees to Coastal.  On May 29, 1996, the Court of Appeals affirmed the judgment.
In December 1996, the Supreme Court of Texas declined to hear the appeal.  The
judgment was paid on May 27, 1997.  Coastal executed a Release of Judgment and
Judgment Lien which has  been recorded in Webb and Zapata Counties.

       FROST.  On November 10, 1994, Frost National Bank filed suit against
TransTexas in the 111th Judicial District

Court, Webb County, Texas, seeking a declaratory judgment determination that
TransTexas failed to properly and accurately calculate royalties under a lease.
The plaintiff had demanded $10 million plus interest.  This  case was settled
in May 1997.

       FARIAS.  On February 15, 1996, Celita Suzana Farias filed a wrongful
death action in the 93rd District Court, Hidalgo County, Texas, against
TransTexas and one of its contractors for fatal injuries suffered by the
plaintiff's husband at the Yzaguirre Heirs #3 Well on February 13, 1996.  The
plaintiff alleges the defendants operated a crane in such  a manner  that  they
were  negligent  and  grossly  negligent.  The plaintiff seeks unspecified
damages.  On March 7, 1996, the mother of the deceased TransTexas employee
filed a petition in intervention also alleging negligence, gross negligence and
malice and seeking unspecified damages.  This litigation was settled in August
1997.

       MCNAMARA.  On June 28, 1996, TransTexas consummated a settlement of
litigation with Tennessee Gas Pipeline Company ("Tennessee") that was filed on
October 14, 1993 in the 244th Judicial District Court,  Ector County, Texas
pursuant to which TransTexas and another plaintiff  received approximately $125
million from Tennessee.  TransTexas' share of the settlement proceeds was $96
million.  On July 2, 1996, John McNamara, Jr. et al. ("The Hubberd Trusts")
filed a new suit against TransTexas in the 241st District Court, Webb County,
Texas asserting that TransTexas had breached its duties to The Hubberd Trusts
under certain oil and gas leases and that TransTexas owed The Hubberd Trusts
25% of the gross settlement proceeds, or approximately $31.25 million.  This
litigation was settled in December 1996.

       KATHRYN M. On June 8, 1995, Kathryn M., Inc., et al., filed suit against
TransAmerican in the 333rd Judicial District Court (subsequently transferred to
the 334th Judicial District Court), Harris County, Texas, alleging that the
plaintiffs, as nonparticipating royalty interest owners in certain leases, are
entitled to receive a portion of the settlement proceeds received  by
TransAmerican from El Paso.   On April 16, 1996, additional nonparticipating
royalty interest owners intervened, making the same claims as the plaintiffs.
In June 1996, TransAmerican  filed its motion for summary judgment.
Plaintiffs also filed a motion for partial summary judgment.  On August 2,
1996, the court denied TransAmerican's motion and plaintiffs' motion.  The
plaintiffs and intervenors agreed on November 15, 1996 to dismiss their claims
without prejudice.

       TERRY/PENROD.  TransAmerican and a group of TransAmerican's former bank
lenders (the "Bank Group") were parties to a consolidated suit filed December
6, 1991, in the United States District Court for the Southern District of
Texas, Houston Division, relating to the interpretation of two third-party
drilling agreements.  Plaintiffs Ensco Offshore Company, f/k/a Penrod Drilling
Corporation, Terry Oil field Supply Co., Inc. and Terry Resources, Inc.
("Terry") sued TransAmerican for approximately $50 million in actual damages
and punitive damages of not less than five times actual damages.   On April 5,
1996, the court entered a final judgment against TransAmerican, TransTexas and
several of their affiliates, in the amount of approximately $43 million, plus
interest.  On April 18, 1996, the court entered a separate judgment against the
same parties for Terry's attorneys' fees of $2 million.  In May 1996,
TransTexas paid Terry approximately $19 million and caused escrowed funds held
for the benefit of the Bank Group of  approximately  $22
 million  to be paid to Terry.  Upon payment of the settlement amount, Terry
released the judgments, released all liens and reassigned to TransTexas a
production payment in certain properties. Terry dismissed an unrelated
administrative proceeding upon payment of the settlement amount described
above.

       GINTHER/WARREN.  Wilbur L. Ginther and Howard C. Warren conveyed a
portion of a lease to Henry J. N. Taub. Taub "farmed out" certain interests to
TransAmerican, and TransAmerican paid royalties to Taub.  The Texas Supreme
Court upheld a judgment in favor of Messrs.  Ginther and Warren against Taub's
interest in the lease.  The lower court judgment had awarded a portion of the
lease to Messrs. Ginther and Warren because Taub's attorney had defrauded
Messrs.  Ginther and Warren with respect to their interest in the lease.  On
November 26, 1986, the estates of Messrs. Ginther and Warren filed an adversary
proceeding in the United States Bankruptcy Court for the Southern District of
Texas, Houston Division (the "Bankruptcy Court") against

TransAmerican seeking damages and claiming that TransAmerican had constructive
notice of their disputes but continued to pay royalties and proceeds of
production to Taub.  TransAmerican filed an interpleader action in the
Bankruptcy Court and deposited the disputed funds accruing from and after
November 1984 into the registry of the court.  On September 30, 1993, the
Bankruptcy Court entered a judgment against TransAmerican in the amount of $6.3
million plus post judgment interest.  On September 15, 1995, the U.S. District
Court for the Southern District of Texas entered an order reversing an award of
interest to Taub and affirming the final judgment in all other respects.
TransTexas appealed the judgment to the Fifth Circuit Court of Appeals.  On
July 2, 1996, TransTexas and the estates of Messrs. Ginther and Warren entered
into a settlement pursuant to which such estates received $3.5 million and a
promissory note for $2.8 million.  The promissory note is payable in 36 equal
monthly installments commencing August 1, 1996, and bears no interest unless an
installment payment is not made.  In addition, TransTexas transferred to such
estates an additional overriding royalty interest in a portion of the lease and
agreed to drill additional wells on the lease.  In conjunction with the
settlement, the estates of Messrs. Ginther and Warren agreed to farm out to
TransTexas an additional working interest in the lease.  In May 1977, the
outstanding balance of the promissory note was paid in full.

       GATX.  On May 14, 1996, GATX Terminals Corporation ("GATX") filed suit
against TARC in the U.S. District Court, Eastern District of Louisiana alleging
breach of an operating agreement to pay GATX $122,500 per month during 1996.
TARC settled this litigation in November 1996.

       NLRB PROCEEDING.  On July 13, 1994, the Oil, Chemical and Atomic Workers
International Union ("OCAW") filed unfair labor practices charges against TARC
with the New Orleans Regional Office of the National Labor Relations Board
("NLRB").  These charges alleged that TARC refused to reinstate 22 former
employees because of their union membership.  The NLRB refused to issue a
complaint and the OCAW appealed the decision to the NLRB General Counsel.  The
decision of the NLRB was upheld in November 1996.


19.  SUPPLEMENTAL GAS AND OIL DISCLOSURE (UNAUDITED)

       The accompanying tables present information concerning TransTexas' gas
and oil producing activities and are prepared in accordance with Statement of
Financial Accounting Standards No. 69, "Disclosures about Oil and Gas Producing
Activities."  Estimates of TransTexas' proved reserves and proved developed
reserves were prepared by Netherland, Sewell & Associates, Inc., an independent
firm of petroleum engineers, based on data supplied to them by TransTexas.
Such estimates are inherently imprecise and may be subject to substantial
revisions as additional information such as reservoir performance, additional
drilling, technological advancements and other factors become available.

       Capitalized costs relating to gas and oil producing activities are as
follows (in thousands of dollars):

    Reserve Quantity Information

       Proved reserves are estimated quantities of natural gas, condensate and
natural gas liquids that geological and engineering data demonstrate with
reasonable certainty to be recoverable in future years from known reservoirs
under existing economic and operating conditions.  Proved developed reserves
are those proved reserves that can be expected to be recovered through existing
wells with existing equipment and operating conditions.  Natural gas quantities
represent wet gas volumes, which include amounts that will be extracted as
natural gas liquids.  TransTexas' estimated

  Standardized Measure Information

       The calculation of estimated future net cash flows in the following
table assumed the continuation of existing economic conditions and applied
year-end prices (except for future price changes as allowed by contract) of gas
and condensate to the expected future production of such reserves, less
estimated future expenditures (based on current costs) to be incurred in
developing and producing those proved reserves.

       The standardized measure of discounted future net cash flows does not
purport, nor should it be interpreted, to present the fair market value of
TransTexas' gas and oil reserves.  These estimates reflect proved reserves only
and ignore, among other things, changes in prices and costs, revenues that
could result from probable reserves which could become proved reserves in
fiscal 1998 or  later  years,  and  the risks  inherent  in reserve  estimates.
The standardized measure of discounted future net cash flows relating to proved
gas and oil reserves is as follows (in thousands of dollars):

         Unless otherwise indicated in this Prospectus, natural gas volumes are
stated at the legal pressure base of the state or area in which the reserves
are located and at 60 degrees Fahrenheit. Natural gas equivalents and crude oil
equivalents are determined using the ratio of six Mcf of natural gas to one
barrel of crude oil, condensate or natural gas liquids.

REFINING TERMS

         "Alkylation" is a process of combining light hydrocarbon molecules to
form high-octane gasoline using a catalyst. Propane and butane by-products are
sold or used as refinery fuel depending on economics.

         "API Gravity" is an indication of density of crude oil or other liquid
hydrocarbons as measured by a system recommended by the American Petroleum
Institute (API), measured in degrees. The lower the API Gravity, the heavier
the compound. For example, asphalt has an API Gravity of 8 degrees and gasoline
has an API Gravity of 50 degrees.

         "Atmospheric residual oil" is the residual from the atmospheric
distillation of crude oil, which can also be used as a refinery feedstock.

raise the temperature of one pound of water by one degree Fahrenheit.

         "Catalytic reforming" is a process which produces high-octane blending
stock for the manufacture of gasoline.

         "Coking" means the thermal destruction of vacuum tower bottoms to
provide lighter hydrocarbons, leaving behind a carbonaceous material called
"coke."

         "Complexity" is a measure of a refinery's downstream processing and
upgrading capacity. A higher complexity rating indicates a greater ability to
upgrade crude oil into higher valued products.

         "Crude oil" means the oil as produced from the well; unrefined
petroleum.

         "Crude oil capacity" means the crude oil processing capacity of the
refinery.

         "dwt" means deadweight-ton; a designation for the size or displacement
of a ship.

         "Feedstocks" are hydrocarbons such as crude oil and natural gas
liquids, that are processed in a refinery or blended directly into refined
products.

         "Fluid catalytic cracking" or "FCC" is a refinery process for
converting vacuum gas oils or other intermediate feedstocks at high temperature
in the presence of a catalyst to produce lighter products such as gasoline and
blend stocks for home heating oil and fuel oil. Catalytic cracking greatly
enhances the efficiency of a refinery by converting a greater percentage of
hydrocarbon compounds to gasoline and other light distillates.

         "Gross refining margin" is the difference between the value of refined
products and the cost of feedstocks expressed in dollars per barrel of crude
oil processed.

         "Hydrodesulfurization" ("HDS") or "Hydrotreating" is the process of
removing sulfur from a hydrocarbon stream in the presence of hydrogen and a
catalyst.

Gentlemen:

         In accordance with your request, we have estimated the proved reserves
and future revenue, as of February 1, 1997, to the TransTexas Gas Corporation
(TransTexas) interest in certain oil and gas properties located in Mississippi,
North Dakota, and Texas. This letter summarizes the results of our report dated
March 26, 1997. This report has been prepared using constant prices and costs
and conforms to the guidelines of the Securities and Exchange Commission (SEC).

         We estimate the net reserves and future net revenue to the TransTexas
interest, as of February 1, 1997, to be:

         Gas volumes are expressed in thousands of standard cubic feet (Mcf) at
the contract temperature and pressure bases. The oil reserves shown include
crude oil and condensate. Oil volumes are expressed in barrels which are
equivalent to 42 United States gallons.

         The estimated reserves and future revenue shown are for proved
developed producing, proved developed non- producing, and proved undeveloped
reserves. In accordance with SEC guidelines, our estimates do not include any
value for probable or possible reserves which may exist for these properties.
Our estimates do not include any value which could be attributed to interests
in undeveloped acreage beyond those tracts for which undeveloped reserves have
been estimated.

         The proved undeveloped category includes 4 wells that were drilled and
logged after February 1, 1997, and 298 identified undrilled locations projected
to be successful wells for which proved reserves have been estimated. The
proved undeveloped locations are projected to be drilled by TransTexas over the
next 4.5 years. The undeveloped wells drilled by TransTexas are projected to
cost an average of approximately $1,421,000 per successful well. These
estimated well costs are held constant in accordance with SEC guidelines.

         Future gross revenue to the TransTexas interest is prior to deducting
state production taxes and ad valorem taxes. Future net revenue is after
deducting these taxes, future capital costs, and operating expenses, but before




                                      B-1

consideration of federal income taxes. Also included in the proved developed
producing reserve category is a gas revenue deduction for the payment of
$13,750 per day to Coastal Oil and Gas Corporation through June 1997. In
addition, we have deducted 2 production payments totaling approximately 47 BCF
carved out of the revenue interest for certain producing wells. These
production payments are projected to be satisfied in May 1999. In accordance
with SEC guidelines, the future net revenue has been discounted at an annual
rate of 10 percent to determine its "present worth." These present worth is
shown to indicate the effect of time on the value of money and should not be
construed as being the fair market value of the properties.

         Gas and oil prices used in the report have been provided by TransTexas
and are based on actual prices received in January 1997. As requested, the gas
price is based on a January 31, 1997 price of $3.09 per MMBtu which includes
allocated natural gas liquids revenue. This price is decreased to reflect
hedged volumes of 100,000 MMBtu per day at $1.71 per MMBtu and 100,000 MMBtu
per day at $1.70 per MMBtu through May 1997. For the purposes of this report,
no value has been included for transportation revenues generated by TransTexas
pipelines. Oil prices used are $24.28 per barrel for North Dakota and $23.61
per barrel for all other areas. Gas and oil prices are held constant in
accordance with SEC guidelines.

         Lease and well operating costs are based on data provided by
TransTexas. These costs include only those direct costs estimated to be
incurred at and below the district and field levels. As requested, these costs
do not include the per-well overhead charges allowed under joint operating
agreements nor do they include the headquarters general and administrative
overhead expenses of TransTexas. Lease and well operating costs are held
constant in accordance with SEC guidelines. Capital costs are included as
required for workovers, new development wells, and production equipment.

         We have made no investigation of potential gas volume and value
imbalances which may have resulted from over delivery or under delivery to the
TransTexas interest. Therefore, our estimates of reserves and future revenue do
not include adjustments for the settlement of any such imbalances; our
projections are based on TransTexas receiving its net revenue interest share of
estimated future gross gas production.

         For the purposes of the report, a field inspection of the properties
has not been performed nor has the mechanical operation or condition of the
wells and their related facilities been examined. We have not investigated
possible environmental liability related to the properties; therefore, our
estimates do not include any costs which may be incurred due to such possible
liability. Also, our estimates do not include any salvage value for the lease
and well equipment nor the cost of abandoning the properties.

         The reserves included in this letter are estimates only and should not
be construed as exact quantities. They may or may not be recovered; if
recovered, the revenues therefrom and the costs related thereto could be more
or less than the estimated amounts. A substantial portion of these reserves are
for undeveloped locations. Reserves for these locations are based on estimates
of reservoir volumes and recovery efficiencies along with analogies to similar
production. As such reserve estimates are usually subject to greater revision
than those based on substantial production and pressure data, it may be
necessary to revise these estimates up or down in the future as additional
wells are drilled and performance data become available. The sales rates,
prices received for the reserves, and costs incurred in recovering such
reserves may vary from assumptions included in this report due to governmental
policies and uncertainties of supply and demand. Also, estimates of reserves
may increase or decrease as a result of future operations.

         In evaluating the information at our disposal concerning the report,
we have excluded from our consideration all matters as to which legal or
accounting, rather than engineering and geological, interpretation may be
controlling.  As in all aspects of oil and gas evaluation, there are
uncertainties inherent in the interpretation of engineering and geological
data; therefore, our conclusions necessarily represent only informed
professional judgments.

TransTexas Gas Corporation
1300 East North Belt
Houston, Texas 77032-2949

Gentlemen:

         In accordance with your request, we have estimated the proved reserves
and future revenue, as of February 1, 1997, to the TransTexas Gas Corporation
(TransTexas) interest in certain oil and gas properties located in Mississippi,
North Dakota, and Texas excluding properties in the Lobo Trend Area being
offered for sale. This letter summarizes the results of the net reserves and
future net revenue presented in our report dated March 26, 1997, excluding the
above sale properties. This report has been prepared using constant prices and
costs and conforms to the guidelines of the Securities and Exchange Commission
(SEC).

         We estimate the net reserves and future net revenue to the TransTexas
interest, as of February 1, 1997, to be:

         Gas volumes are expressed in thousands of standard cubic feet (Mcf) at
the contract temperature and pressure bases. The oil reserves shown include
crude oil and condensate. Oil volumes are expressed in barrels which are
equivalent to 42 United States gallons.

         The estimated reserves and future revenue shown are for proved
developed producing, proved developed non- producing, and proved undeveloped
reserves. In accordance with SEC guidelines, our estimates do not include any
value for probable or possible reserves which may exist for these properties.
Our estimates do not include any value which could be attributed to interests
in undeveloped acreage beyond those tracts for which undeveloped reserves have
been estimated.

         The proved undeveloped category includes 4 wells that were drilled and
logged after February 1, 1997, and 111 identified undrilled locations projected
to be successful wells for which proved reserves have been estimated. The
proved undeveloped locations are projected to be drilled by TransTexas over the
next 4.2 years. The undeveloped wells drilled by TransTexas are projected to
cost an average of approximately $1,780,000 per successful well. These
estimated well costs are held constant in accordance with SEC guidelines.

         Future gross revenue to the TransTexas interest is prior to deducting
state production taxes and ad valorem taxes. Future net revenue is after
deducting these taxes, future capital costs, and operating expenses, but before
consideration of federal income taxes. Also included in the proved developed
producing reserve category is a gas revenue deduction for the payment of
$13,750 per day to Coastal Oil and Gas Corporation through June 1997. In
accordance with SEC guidelines, the future net revenue has been discounted at
an annual rate of 10 percent to determine its "present worth." The present
worth is shown to indicate the effect of time on the value of money and should
not be construed as being the fair market value of the properties.

         Gas and oil prices used in the report have been provided by TransTexas
and are based on actual prices received in January 1997. As requested, the gas
price is based on a January 31, 1997 price of $3.09 per MMBtu which includes
allocated natural gas liquids revenue. This price is decreased to reflect
hedged volumes for all properties including those offered for sale of 100,000
MMBtu per day at $1.71 per MMBtu and 100,000 MMBtu per day at $1.70 per MMBtu
through May 1997. For the purposes of this report, no value has been included
for transportation revenues generated by TransTexas pipelines. Oil prices used
are $24.28 per barrel for North Dakota and $23.61 per barrel for all other
areas.  Gas and oil prices are held constant in accordance with SEC guidelines.

         Lease and well operating costs are based on data provided by
TransTexas. These costs include only those direct costs estimated to be

                                    PART II

                     INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

         The Company is a Delaware corporation.  Section 145 of the Delaware
General Corporation Law (the "DGCL") provides that any person may be
indemnified by a Delaware corporation against expenses (including attorneys'
fees), judgments, fines and amounts paid in settlement actually and reasonably
incurred by him in connection with any threatened, pending or completed action,
suit or proceeding in which such person is made a party by reason of his being
or having been a director, officer, employee or agent of the Company.  The
statute provides that indemnification pursuant to its provisions is not
exclusive of other rights of indemnification to which a person may be entitled
under any bylaw, agreement, vote of stockholders or disinterested directors or
otherwise.

         Section nine of the Company's Certificate of Incorporation provides
that directors of the Company shall not, to the fullest extent permitted by the
DGCL, as amended from time to time, be liable to the Company or its
stockholders for monetary damages for breach of their fiduciary duty to the
Company or the Company's stockholders.

         The Company has purchased customary directors' and officers' liability
insurance policies for its directors and officers.  The Bylaws of the Company
and agreements with directors and officers also provide for indemnification for
amounts (i) in respect of the deductibles for such insurance policies and (ii)
that exceed the liability limits of such insurance policies.  Such
indemnification may be made even though directors and officers would not
otherwise be entitled to indemnification under other provisions of the Bylaws
or such agreements.

ITEM 22.     UNDERTAKINGS.

             The undersigned registrant hereby undertakes:

             (1)          That, for purposes of determining any liability under
the Act, the information omitted from the form of prospectus filed as part of
this registration statement in reliance upon Rule 430A and contained in a form
of prospectus filed by the registrant pursuant to rule 424(b)(1) or (4) or
497(h) under the Act shall be deemed to be part of this registration statement
as of the time it was declared effective.

             (2)          That, for the purpose of determining any liability
under the Act, each post-effective amendment that contains a form of prospectus
shall be deemed to be a new registration statement relating to the securities
offered therein, and the offering of such securities at that time shall be
deemed to be the initial bona fide offering thereof.

             (3)          That, insofar as indemnification for liabilities
arising under the Act may be permitted to directors, officers and controlling
persons of the registrant pursuant to the foregoing provisions, or otherwise,
the registrant has been informed that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Act and is, therefore, unenforceable.  In the event that a claim for
indemnification against such liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer or controlling
person of the registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the registrant will, unless in
the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the Act and
will be governed by the final adjudication of such issue.

             (4)          To respond to requests for information that is
incorporated by reference into the prospectus pursuant to Items 4, 10(b), 11,
or 13 of this Form, within one business day of receipt of such request, and to
send the incorporated documents by first class mail or other equally prompt
means.  This includes information contained in documents filed subsequent to
the effective date of the registration statement through the date of responding
to the request.

             (5)          To supply by means of a post-effective amendment all
information concerning a transaction, and the company being acquired involved
therein, that was not the subject of and included in the registration statement
when it became effective.

       6.     Representations and Warranties of the Issuer.  The Issuer
represents and warrants to the Purchaser that:

              (a)    Each of the Preliminary Offering Circular and the Offering
       Circular, both including the Annual Reports on Form 10-K for the fiscal
       year ended January 31, 1997 of each of the TransAmerican Entities, as of
       its respective date does not, and the Offering Circular as of the
       Closing Date will not, and each supplement or amendment thereto as of
       its date will not, contain any untrue statement of a material fact or
       omit to state any material fact (except, in the case of the Preliminary
       Offering Circular, for pricing terms and other financial terms
       intentionally left blank) required to be stated therein or necessary in
       order to make the statements therein, in the light of the circumstances
       under which they were made, not misleading.  Any reference herein to the
       Preliminary Offering Circular or the Offering Circular shall be deemed
       to refer to and include the most recent Annual Reports on Form 10-K of
       each of the TransAmerican Entities and all subsequent documents filed by
       any of the TransAmerican Entities with the Commission pursuant to
       Section 13(a), 13(c) or 15(d) of the Exchange Act on or prior to the
       date of the Preliminary Offering Circular or the Offering Circular, as
       the case may be, and any reference herein to the Preliminary Offering
       Circular or the Offering Circular, as the case may be, as amended or
       supplemented, as of any specified date, shall be deemed to include (i)
       any documents filed by any of the TransAmerican Entities with the
       Commission pursuant to Section 13(a), 13(c) or 15(d) of the Exchange Act
       after the date of the Preliminary Offering Circular or the Offering
       Circular, as the case may be, and prior to such specified date; and all
       documents filed under the Exchange Act (the "Exchange Act Reports") are
       so deemed to be included in the Preliminary Offering Circular or the
       Offering Circular, as the case may be, or any amendment or supplement
       thereto.  The Exchange Act Reports, when they were or are filed with the
       Commission, conformed or will conform in all material respects to the
       applicable requirements of the Exchange Act and the applicable rules and
       regulations of the Commission thereunder.  No injunction or order has
       been issued that either (i) asserts that any of the Transactions is
       subject to the registration requirements of the Securities Act or (ii)
       would prevent or suspend the issuance or sale of the Notes or the use of
       the Preliminary Offering Circular, the Offering Circular, or any
       amendment or supplement thereto, in any jurisdiction.  Each of the
       Preliminary Offering Circular and the Offering Circular, as of their
       respective dates contained, and the Offering Circular as amended or
       supplemented as of the Closing Date will contain, all the information
       specified in, and meet the requirements of, Rule 144A(d)(4) under the
       Securities Act.

              (b)    Each of the Issuer and each Subsidiary (as defined below)
       (i) has been duly incorporated, is validly existing and is in good
       standing under the laws of its jurisdiction of organization, (ii) has
       full corporate power and authority to conduct its business and to own,
       lease and operate its properties and assets as described in the Offering
       Circular and (iii) is duly registered and qualified to conduct its
       business and is in good standing as a foreign corporation authorized to
       do business in each jurisdiction or place in which the nature of such
       businesses or the ownership or leasing of such properties requires such
       registration or qualification, except where the failure to be so
       registered or qualified would not have a Material Adverse Effect (as
       defined below in Section 6(d)).

              (c)    Immediately following the Closing, the only direct or
       indirect subsidiaries of the Issuer (collectively, the "Subsidiaries")
       will be TARC, TransTexas and the other corporations identified on
       Schedule 6(c).  There are no outstanding (x) securities convertible into
       or





                                       9
<PAGE>   10
       exchangeable for any capital stock of the Issuer or any of the
       Subsidiaries, (y) options, warrants or other rights to purchase or
       subscribe to capital stock of the Issuer or any of the Subsidiaries or
       securities convertible into or exchangeable for capital stock of the
       Issuer or any of the Subsidiaries (other than the TARC Warrants (as
       defined in below in Section 9(a)(vii))) or (z) contracts, commitments,
       agreements, understandings, arrangements, calls or claims of any kind
       relating to the issuance of any capital stock of the Issuer or any of
       the Subsidiaries, any such convertible or exchangeable securities or any
       such options, warrants or rights (other than the Reimbursement and
       Credit Agreement dated as of January 25, 1996, as amended, between
       TransTexas and SunAmerica, Inc.).  Immediately following the Closing,
       the Issuer will not directly or indirectly own any capital stock or
       other equity interest in any person other than the Subsidiaries.

              (d)    Immediately following the Closing, the total authorized
       capital stock of the Issuer shall consist of (i) 100,000 shares of
       common stock, $0.01 par value, of which 9,000 shares shall be issued and
       outstanding and (ii) 1,000 shares of preferred stock, $0.01 par value.
       All of the outstanding shares of capital stock of the Issuer have been
       duly authorized and validly issued, and all of the outstanding shares of
       common stock of the Issuer are owned beneficially and of record by
       TransAmerican Natural Gas Corporation, a Texas corporation.  Immediately
       following the Closing, the total authorized capital stock of TransTexas
       shall consist of 100,000,000 shares of common stock, $0.01 par value, of
       which 74,000,000 shares shall be issued and outstanding.  All of the
       outstanding shares of capital stock of TransTexas have been duly
       authorized and validly issued, are fully paid and nonassessable, and
       were not issued in violation of, and are not subject to, any preemptive
       or similar rights.  The Issuer owns 40,000,000 of such shares
       beneficially, free and clear of Liens (except for Liens securing the
       Notes and Liens securing the TARC Notes).  Immediately following the
       Closing, the total authorized capital stock of TARC shall consist of
       100,000,000 shares of common stock, $0.01 par value, of which 30,000,000
       shares shall be issued and outstanding.  All of the outstanding shares
       of capital stock of TARC have been duly authorized and validly issued,
       are owned beneficially and of record by the Issuer, free and clear of
       Liens (except Liens securing the Notes and Liens securing the TARC
       Notes), are fully paid and nonassessable, and were not issued in
       violation of, and are not subject to, any preemptive or similar rights.
       The table under the caption "Capitalization of TEC" in the Offering
       Circular (including the footnotes thereto) sets forth, as of its date,
       (i) the capitalization of the Issuer and its Subsidiaries on a
       consolidated basis and (ii) the pro forma capitalization of the Issuer
       and its subsidiaries on a consolidated basis after giving effect to the
       transactions described in the Offering Circular.  The table under the
       caption "Capitalization of TransTexas" in the Offering Circular
       (including the footnotes thereto) sets forth, as of its date, (i) the
       capitalization of TransTexas and its Subsidiaries on a consolidated
       basis and (ii) the pro forma capitalization of TransTexas and its
       Subsidiaries on a consolidated basis after giving effect to the
       transactions described in the Offering Circular.  The table under the
       caption "Capitalization of TARC" in the Offering Circular (including the
       footnotes thereto) sets forth, as of its date, (i) the capitalization of
       TARC and its subsidiaries on a consolidated basis and (ii) the pro forma
       capitalization of TARC and its Subsidiaries on a consolidated basis
       after giving effect to the transactions described in the Offering
       Circular.  Except as set forth in such tables, immediately following the
       Closing, neither the Issuer nor any of the Subsidiaries shall have any
       liabilities, absolute, accrued, contingent or otherwise other than (x)
       liabilities that are recorded or disclosed in the Financial Statements
       (defined below), or (y) liabilities incurred subsequent to the date
       thereof in the ordinary course of business, consistent with past
       practice, that would not, singly or in the aggregate, reasonably be
       expected to have a material adverse effect (a "Material Adverse Effect")
       on (i) the properties, business, prospects, operations,





                                       10
<PAGE>   11
       earnings, assets, liabilities or condition (financial or otherwise) of
       any of the TransAmerican Entities and its Subsidiaries, taken as a
       whole, (ii) the ability of any TransAmerican Entity to perform its
       obligations under any of the Documents or (iii) the perfection or
       priority of any Security Interest in any portion of the Collateral.

              (e)    Except for this Agreement, the Registration Rights
       Agreement, the other Documents and agreements previously disclosed in
       documents filed by any of the TransAmerican Entities with the
       Commission, neither the Issuer nor any of the Subsidiaries has entered
       into any pending agreement (i) to register its securities under the
       Securities Act or (ii) other than as contemplated by the Offering
       Circular, to purchase or offer to purchase any securities of the Issuer,
       any of the Subsidiaries or any of their respective affiliates.

              (f)    Each TransAmerican Entity has all requisite power and
       authority to enter into, deliver and perform its obligations under the
       Documents to which it is a party and to consummate the Transactions.
       Each of the Documents has been duly and validly authorized by each
       TransAmerican Entity that is, or will be, a party thereto, and this
       Agreement is, and when executed and delivered on the Closing Date
       (assuming the due authorization, execution and delivery thereof by the
       other parties thereto) each other Document will be, a legal, valid and
       binding obligation of each TransAmerican Entity that is a party hereto
       or thereto, enforceable against each such person in accordance with its
       terms, subject to (i) any applicable bankruptcy, insolvency,
       reorganization, moratorium and similar laws relating to or affecting
       creditor's rights and remedies generally and (ii) general principles of
       equity (regardless of whether enforcement is sought in a proceeding at
       equity or at law).  When executed and delivered, each Document will
       conform in all material respects to the description thereof in the
       Offering Circular.  On the Closing Date, the Indenture will conform to
       the requirements of the Trust Indenture Act of 1939, as amended (the
       "TIA"), applicable to an indenture that is required to be qualified
       under the TIA.

              (g)    The Series A Notes have been duly and validly authorized
       by the Issuer for issuance and sale to the Purchaser pursuant to this
       Agreement and, when executed and authenticated in accordance with the
       terms of the Indenture and delivered to and paid for by the Purchaser in
       accordance with the terms hereof, will be legal, valid and binding
       obligations of the Issuer, enforceable against the Issuer in accordance
       with their terms, subject to (i) any applicable bankruptcy, insolvency,
       reorganization, moratorium and similar laws relating to or affecting
       creditor's rights and remedies generally, and (ii) general principles of
       equity (regardless of whether enforcement is sought in a proceeding at
       equity or at law).  The Series B Senior Secured Notes and the Series B
       Senior Secured Discount Notes have been duly and validly authorized by
       the Issuer and, when executed, authenticated and delivered in accordance
       with the terms of the Indenture and the Registration Rights Agreement,
       will be legal, valid and binding obligations of the Issuer, enforceable
       against the Issuer in accordance with their terms, subject to (i) any
       applicable bankruptcy, insolvency, reorganization, moratorium and
       similar laws relating to or affecting creditors' rights and remedies
       generally and (ii) general principles of equity (regardless of whether
       enforcement is sought in a proceeding at equity or at law).

              (h)    Neither the Issuer nor any of the Subsidiaries is (i) in
       violation of its respective charter or by-laws or similar organizational
       documents, each as amended to the Closing Date (collectively, "Charter
       Documents"), other than violations that would not, singly or in the
       aggregate, result in a Material Adverse Effect, (ii) in violation of any
       Federal, state, local or





                                       11
<PAGE>   12
       foreign statute, law (including, without limitation, common law) or
       ordinance, or any judgment, decree, rule, regulation or order
       (collectively, "Applicable Law") of any government, governmental or
       regulatory agency or body, court or arbitrator, domestic or foreign
       (each, a "Governmental Authority"), other than violations that would
       not, singly or in the aggregate, result in a Material Adverse Effect or
       (iii) other than breaches or defaults that would not, singly or in the
       aggregate, result in a Material Adverse Effect, in breach of or default
       under (with the passage of time or otherwise) any bond, debenture, note
       or other evidence of indebtedness, indenture, mortgage, deed of trust,
       lease or any other agreement or instrument to which any such person is a
       party or by which any of them or their respective property is bound
       (collectively, "Applicable Agreements").  There exists no condition
       that, with the passage of time or otherwise, would constitute a
       violation of such Charter Documents or Applicable Laws or a breach of or
       default under any Applicable Agreement or result in the imposition of
       any penalty or the acceleration of any indebtedness, other than
       breaches, violations, penalties, defaults or conditions that shall have
       been waived prior to Closing or that would not, singly or in the
       aggregate, result in a Material Adverse Effect.

              (i)    Neither the execution, delivery or performance of the
       Documents nor the consummation of the Transactions will conflict with,
       violate, constitute a breach of or a default (with the passage of time
       or otherwise) under, require the consent of any person (other than
       consents obtained prior to Closing) under, result in the imposition of a
       Lien on any assets of the Issuer or any of the Subsidiaries (except
       pursuant to the Documents), or result in an acceleration of indebtedness
       pursuant to (i) the Charter Documents of the Issuer or any of the
       Subsidiaries, (ii) any Applicable Agreement, other than such breaches,
       violations or defaults that shall have been waived prior to Closing or
       would not, singly or in the aggregate, result in a Material Adverse
       Effect or (iii) any Applicable Law.  After giving effect to the
       Transactions, no Default or Event of Default (as defined in the
       Indenture) will exist.

              (j)    No permit, authorization, approval, consent, certificate,
       license or order of, or filing, registration or qualification with, any
       Governmental Authority (collectively, "Permits") and no approval or
       consent of any other person, is required in connection with, or as a
       condition to, the execution, delivery or performance of any of the
       Documents or the consummation of any of the Transactions, other than
       such Permits (i) as have been made or obtained on or prior to the
       Closing Date, (ii) as are not required to be made or obtained on or
       prior to the Closing Date that will be made or obtained when required or
       (iii) the failure of which to make or obtain would not, singly or in the
       aggregate, result in a Material Adverse Effect.

              (k)    Except as adequately disclosed in the Offering Circular,
       (A) there is no action, claim, suit or proceeding (including, without
       limitation, an investigation or partial proceeding, such as a
       deposition), domestic or foreign (collectively, "Proceedings"), pending
       or, to the knowledge of the Issuer or the Subsidiaries, threatened
       against the Issuer or the Subsidiaries, that (i) would be required to be
       described in the Offering Circular or Preliminary Offering Circular, if
       Item 103 of Regulation S-K under the Securities Act were to apply to the
       Offering Circular, (ii) seek to restrain, enjoin, prevent the
       consummation of, or otherwise challenges any of the Documents or any of
       the Transactions or (iii) could, singly or in the aggregate, reasonably
       be expected to have a Material Adverse Effect and (B) neither the Issuer
       nor any of the Subsidiaries is subject to any judgment, order, decree,
       rule or regulation of any Governmental Authority that could, singly or
       in the aggregate, have a Material Adverse Effect.





                                       12
<PAGE>   13
              (l)    Each of the Issuer and the Subsidiaries has such Permits
       as are necessary to own, lease and operate the properties and to conduct
       the businesses described in the Offering Circular other than those the
       failure of which to have could not, singly or in the aggregate,
       reasonably be expected to result in a Material Adverse Effect.  All such
       Permits are in full force and effect.  None of the Issuer and the
       Subsidiaries has received any notice or threat of Proceedings relating
       to the revocation or modification of any such Permits.  Each of the
       Issuer and the Subsidiaries has fulfilled and performed in all material
       respects all of its current obligations with respect to such Permits,
       subject to such qualifications as may be set forth in the Offering
       Circular.  The property and business of the Issuer and the Subsidiaries
       conform in all material respects to the descriptions thereof contained
       in the Offering Circular and Preliminary Offering Circular.  No event
       has occurred that allows, or after notice or lapse of time would allow,
       the revocation or termination by the issuer of any such Permits or which
       results in any material impairment of the rights of the holder of any
       such Permits.  Neither the Issuer nor any of the Subsidiaries has any
       reason to believe that any issuer is considering limiting, suspending or
       revoking any such Permit.

              (m)    Except as would not have a Material Adverse Effect,
       immediately following the Closing, the Issuer and the Subsidiaries (i)
       will have good, valid and defensible title, free and clear of all Liens
       (except for Permitted Liens (as defined below)), to substantially all
       property and assets described in the Offering Circular as being owned by
       them after the Lobo Sale (as defined in the Offering Circular),
       including, without limitation, the assets described in the reserve
       report of Netherland, Sewell & Associates, Inc., dated April 28, 1997
       (the "Reserve Report"), which report is included as Annex C to the
       Preliminary Offering Circular and (ii) will be entitled to enjoy
       peaceful and undisturbed possession under all leases to which any of
       them is a party as lessee.  "Permitted Liens" means, collectively, (i)
       Permitted Liens as defined in the Indenture, (ii) Liens on assets
       securing Indebtedness outstanding under the Notes and (iii) Purchase
       Money Liens as defined in the Indenture.  All Applicable Agreements are
       in full force and effect and are legal, valid and binding obligations of
       the Issuer or the Subsidiaries party to such agreement, and no default
       has occurred or is continuing thereunder, other than such defaults that
       would not, singly or in the aggregate, have a Material Adverse Effect.
       TransTexas and its subsidiaries own, in the aggregate, respective
       undivided working interests and net revenue interests in the leases upon
       which the Reserve Report is based of not materially less, in the
       aggregate, than those set forth in the Reserve Report.  Except as
       described in the Offering Circular, with respect to the leases covering
       all wells and lands to which value has been ascribed in the Reserve
       Report, TransTexas and its subsidiaries have valid, subsisting and
       enforceable leases, superior and paramount to all other leases
       respecting the properties to which they pertain, and all rentals,
       royalties and other amounts due and payable in accordance with the terms
       of the leases have been duly paid or provided for, and such leases are
       in full force and effect, except, in each case, for any inaccuracies in
       the foregoing that would not, singly or in the aggregate, result in a
       Material Adverse Effect.  The Issuer and the Subsidiaries maintain
       insurance covering their properties, operations, personnel and
       businesses against such losses and risks as they reasonably deem
       adequate in accordance with customary industry practice.  Any such
       insurance is outstanding and duly in force.

              (n)    Upon execution and delivery thereof, the Issuer Pledge
       Agreement will create, in favor of the Collateral Agent, for the benefit
       of the holders of the Notes, a valid grant of a security interest in the
       Collateral and the proceeds thereof and, upon the filings or the
       recording required by the Issuer Pledge Agreement, the Collateral Agent
       will have, other than with respect to Permitted Liens, a first priority
       perfected security interest in the Collateral, subject to the prior





                                       13
<PAGE>   14
       liens securing the TARC Notes and the prior liens securing the
       TransTexas Senior Notes (as defined below in Section 9(a)(vii)).  Upon
       execution and delivery thereof, each of the TARC Mortgage, the TARC
       Pledge, the TransTexas Texas Mortgage, the TransTexas Louisiana
       Mortgage, the TransTexas Mississippi Mortgage, the TransTexas Alabama
       Mortgage, the TransTexas North Dakota Mortgage and the TransTexas Pledge
       will create, in favor of the Issuer, a valid grant of a security
       interest in the collateral described in such instrument and the proceeds
       thereof and, upon the filings or the recording required by such
       instrument, the Issuer will have, other than with respect to Permitted
       Liens, a first priority perfected security interest in such collateral,
       subject to the prior liens securing the TARC Notes and the prior liens
       securing the TransTexas Senior Notes (as defined below in Section
       9(a)(vii)).

              (o)    All tax returns required to be filed by the Issuer and the
       Subsidiaries in any jurisdiction (including foreign jurisdictions) have
       been filed (other than Forms 5500 or state tax returns, the failure of
       which to timely file cannot result in any material penalty) and, when
       filed, all such returns were accurate in all material respects, and all
       taxes, assessments, fees and other charges (including, without
       limitation, withholding taxes, penalties and interest) due or claimed to
       be due from such entities have been paid, other than those being
       contested in good faith by appropriate proceedings, or those that are
       currently payable without penalty or interest and, in each case, for
       which an adequate reserve or accrual has been established on the books
       and records of the Issuer or the Subsidiary, as applicable, in
       accordance with generally accepted accounting principles of the United
       States of America, consistently applied ("GAAP").  There are no actual
       or, to the knowledge any of the TransAmerican Entities, proposed
       additional tax assessments for any fiscal period against the Issuer or
       any of the Subsidiaries that could, singly or in the aggregate, have a
       Material Adverse Effect.  Other than as disclosed in the Offering
       Circular, the charges, accruals and reserves on the books of each of the
       Issuer and the Subsidiaries in respect of any income and tax liability
       for any years not finally determined are adequate to meet any
       assessments or re-assessments for additional income tax for any years
       not finally determined.

              (p)    The Issuer and the Subsidiaries own, or are licensed
       under, and have the right to use, all patents, patent rights, licenses,
       inventions, copyrights, know-how (including trade secrets and other
       unpatented and/or unpatentable proprietary or confidential information,
       systems or procedures), trademarks, service marks and trade names
       (collectively, "Intellectual Property") currently used in, or necessary
       for the conduct of, their businesses as set forth in the Offering
       Circular, other than failures to own or be licensed under or have the
       rights to use, patents, patent rights, licenses, inventions, copyrights,
       know-how, trademarks, service marks and trade names, which failures
       would not, singly or in the aggregate have a Material Adverse Effect.
       No claims have been asserted by any person challenging the use of any
       such Intellectual Property by the Issuer or any of the Subsidiaries or
       questioning the validity or effectiveness of any license or agreement
       related thereto, to the knowledge of the Issuer and the Subsidiaries,
       there is no valid basis for any such claim (other than any claims that
       would not, singly or in the aggregate, have a Material Adverse Effect),
       and to the knowledge of the Issuer, the use of such Intellectual
       Property by the Issuer and the Subsidiaries will not infringe on the
       Intellectual Property rights of any other person.

              (q)    Each of the Issuer and the Subsidiaries maintains a system
       of internal accounting controls sufficient to provide reasonable
       assurance that (i) material transactions are executed in accordance with
       management's general or specific authorization, (ii) material
       transactions are





                                       14
<PAGE>   15
       recorded as necessary to permit preparation of financial statements in
       conformity with GAAP, and to maintain asset accountability and (iii) the
       recorded accountability for assets is compared with the existing assets
       at reasonable intervals and appropriate action is taken with respect to
       any material differences.

              (r)    Each of the audited consolidated financial statements of
       the Issuer and related notes contained or incorporated by reference in
       the Offering Circular (the "Financial Statements") present fairly in all
       material respects the consolidated financial position, results of
       operations and cash flows of the Issuer and its Subsidiaries, as of the
       respective dates and for the respective periods to which they apply, and
       have been prepared in accordance with GAAP and the requirements of
       Regulation S-X that would be applicable if the Offering Circular were a
       prospectus included in a registration statement on Form S-1 filed under
       the Securities Act.  The summary historical financial data included in
       the Offering Circular have been derived accurately from the Financial
       Statements.  The pro forma consolidated financial statements and related
       notes for the year ended January 31, 1997 included in the Offering
       Circular (i) comply with the rules and guidelines of the Commission with
       respect to pro forma financial statements, (ii) have been prepared on a
       basis consistent with the Financial Statements, except for the pro forma
       adjustments specified therein, and (iii) are based on good faith,
       reasonable estimates and assumptions of the Issuer.  The summary pro
       forma financial information included in the Offering Circular have been
       derived from such pro forma financial statements.  All other financial
       and statistical data included in the Offering Circular are fairly and
       accurately presented.

              (s)    Subsequent to the respective dates as of which information
       is given in the Offering Circular, except as adequately disclosed in the
       Offering Circular, (i) neither the Issuer nor any of the Subsidiaries
       has issued any securities, or incurred any material liabilities or
       obligations, direct or contingent, for borrowed money, or entered into
       any transaction, not in the ordinary course of business, or entered into
       any transaction with any Affiliate that would otherwise be required to
       be disclosed in the Offering Circular, (ii) there has not been any
       material change in the capital stock or other equity or any material
       increase in long-term indebtedness or short-term indebtedness of any of
       them, or any payment of or declaration to pay any dividends or any other
       distribution with respect to any of them, and (iii) there has not been
       any change or development, regardless of whether arising in the ordinary
       course of business, involving or which may reasonably be expected to
       involve a material adverse change in the properties, business,
       prospects, operations, earnings, assets, liabilities or condition
       (financial or otherwise) of any of the TransAmerican Entities and its
       Subsidiaries taken as a whole (each of clauses (i), (ii) and (iii), a
       "Material Adverse Change").  There is no event that is reasonably likely
       to occur, which if it were to occur, could reasonably be expected to,
       singly or in the aggregate, have a Material Adverse Effect, except such
       events that have been adequately disclosed in the Offering Circular.

              (t)    Immediately following the Closing, and after giving pro
       forma effect to the Transactions, (i) the present fair salable value of
       the assets of each TransAmerican Entity will exceed the amount that will
       be required to pay its probable liability on its existing debts
       (including contingent and unliquidated debts) as they become absolute
       and matured, (ii) the sum of the debts of each TransAmerican Entity
       (including contingent and unliquidated debts) will be less than all of
       its assets at a fair valuation, and (iii) no TransAmerican Entity will
       be engaged in a business or intend to engage in a business for which its
       remaining unencumbered assets constitute unreasonably





                                       15
<PAGE>   16
       small capital.  Neither the Issuer nor any of its Subsidiaries intends
       to incur or believes that it will incur debts beyond its ability to pay
       as they mature.

              (u)    Except as contemplated by this Agreement, neither the
       Issuer nor any of its Affiliates has (i) taken, directly or indirectly,
       any action designed to cause or to result in, or that has constituted or
       which might reasonably be expected to constitute, the stabilization or
       manipulation of the price of any security of any of them to facilitate
       the sale or resale of any of the Notes or (ii) except as disclosed in
       the Offering Circular, (A) sold, bid for, purchased, or paid anyone any
       compensation for soliciting purchases of, any of the Notes or (B) paid
       or agreed to pay to any person any compensation for soliciting another
       to purchase any other securities of any of them.  Neither the Issuer nor
       any of its Affiliates has distributed and, prior to the later to occur
       of (A) the Closing Date or (B) completion of the distribution of the
       Notes, will distribute without your prior written consent any offering
       material in connection with the offering and sale of the Notes other
       than the Offering Circular, the Preliminary Offering Circular or other
       materials, if any, permitted by the Securities Act.

              (v)    To the knowledge of the Issuer and its Subsidiaries,
       neither the Issuer or any Subsidiary nor any of their respective
       subsidiaries, predecessors, employees or agents has made any payment of
       funds of the Issuer or any Subsidiary or any of their respective
       subsidiaries or predecessors, or has received any funds, in violation of
       any law or rule or regulation, which payment, receipt or retention of
       funds is of a character required to be disclosed in the Offering
       Circular.

              (w)    No registration under the Securities Act, and no
       qualification of the Indenture under the TIA is required for the sale of
       the Series A Notes to the Purchaser as contemplated hereby or for the
       Exempt Resales, assuming (i) that the Eligible Purchasers who buy the
       Series A Notes in the Exempt Resales are QIBs and (ii) the accuracy of
       the Purchaser's representations contained herein regarding the absence
       of general solicitation in connection with the sale of the Series A
       Notes to the Purchaser and the Exempt Resales.  No form of general
       solicitation or general advertising was used by the Issuer or any of its
       Affiliates or any of their representatives (other than the Purchaser,
       with respect to which the TransAmerican Entities make no representation)
       in connection with the offer and sale of any of the Series A Notes or in
       connection with Exempt Resales.  No securities of the same class as any
       of the Notes have been offered, issued or sold by the Issuer or any of
       its Affiliates within the six-month period immediately prior to the date
       hereof.

              (x)    When the Notes are issued and delivered pursuant to this
       Agreement, the Notes will not be of the same class (within the meaning
       of Rule 144A under the Securities Act) as securities that are listed on
       a national securities exchange registered under Section 6 of the
       Exchange Act or quoted in a U.S. automated inter-dealer quotation
       system.

              (y)    Neither the Issuer nor any of its "Affiliates" is a "party
       in interest" or a "disqualified person" with respect to any employee
       benefit plans except for those described in the Offering Circular.  No
       condition exists or event or transaction has occurred in connection with
       any employee benefit plan that could result in the Issuer or any such
       "Affiliate" incurring any liability, fine or penalty that could, singly
       or in the aggregate, have a Material Adverse Effect.  With respect to
       any employee pension benefit plan that is subject to Title IV of ERISA,
       (i) the fair market value





                                       16
<PAGE>   17
       of the assets of such employee pension benefit plan equals or exceeds
       the present value of the liabilities of such pension plan (as determined
       in accordance with the actuarial methods and assumptions set forth in
       the latest actuarial report for such employee pension benefit plan),
       except where the failure to so equal or exceed would not, singly or in
       the aggregate, have a Material Adverse Effect and (ii) there exists no
       accumulated funding deficiency which could, singly or in the aggregate,
       have a Material Adverse Effect.  The terms "employee benefit plan,"
       "employee pension benefit plan," and "party in interest" shall have the
       meanings assigned to such terms in Section 3 of the Employee Retirement
       Income Act of 1974, as amended, or the rules and regulations promulgated
       thereunder ("ERISA"), the term "Affiliate" shall have the meaning
       assigned to such term in Section 407(d)(7) of ERISA, and the term
       "disqualified person" shall have the meaning assigned to such term in
       section 4975 of the Internal Revenue Code of 1986, as amended, or the
       rules, regulations and published interpretations promulgated thereunder
       the ("Code").

              (z)    None of the Transactions will violate or result in a
       violation of Section 7 of the Exchange Act (including, without
       limitation, Regulation T (12 C.F.R. Part 220), Regulation U (12 C.F.R.
       Part 221) or Regulation X (12 C.F.R. Part 224) of the Board of Governors
       of the Federal Reserve System).

              (aa)   Neither the Issuer nor any of the Subsidiaries has dealt
       with any broker, finder, commission agent or other person (other than
       the Purchaser) in connection with the Transactions (other than the Lobo
       Sale) and neither the Issuer nor any of the Subsidiaries is under any
       obligation to pay any broker's fee or commission in connection with such
       transactions (other than with respect to the Lobo Sale and commissions
       and fees to the Purchaser as set forth in the Offering Circular).

              (bb)   Neither the Issuer nor any Subsidiary is engaged in any
       unfair labor practice.  Except as adequately disclosed in the Offering
       Circular, there is (i) no unfair labor practice complaint or other
       proceeding pending or, to the knowledge of the Issuer, threatened
       against the Issuer or any of the Subsidiaries before the National Labor
       Relations Board or any state, local or foreign labor relations board or
       any industrial tribunal, and to the knowledge of the Issuer, no
       grievance or arbitration proceeding arising out of or under any
       collective bargaining agreement is so pending or threatened, (ii) no
       strike, labor dispute, slowdown or stoppage pending or, to the knowledge
       of the Issuer after due inquiry, threatened against the Issuer or any of
       the Subsidiaries, and (iii) no union representation question existing
       with respect to the employees of the Issuer or any of the Subsidiaries,
       and to the knowledge of the Issuer, no union organizing activities are
       taking place that, singly or in the aggregate, could reasonably be
       expected to have a Material Adverse Effect.

              (cc)   Except as adequately disclosed in the Offering Circular,
       neither the Issuer nor any Subsidiary is involved in any labor dispute
       nor, to the knowledge of the Issuer or any Subsidiary, is any such
       dispute threatened.

              (dd)   Except as set forth in the Offering Circular, or as could
       not reasonably be expected to have a Material Adverse Effect:

                     (i)    each of the Issuer and its Subsidiaries and, to the
              best knowledge of the Issuer and its Subsidiaries, any Person for
              whom any of the foregoing are or may be





                                       17

              responsible by law or contract, is in compliance with all
              federal, state, local and foreign laws and regulations relating
              to pollution or protection of human health or the environment
              (including, without limitation, ambient air, surface water,
              ground water, land surface or subsurface strata), including,
              without limitation, laws and regulations relating to emissions,
              discharges, releases or threatened releases of Materials of
              Environmental Concern (as defined below), or otherwise relating
              to the manufacture, processing, distribution, use, treatment,
              storage, disposal, transport or handling of Materials of
              Environmental Concern (collectively, "Environmental Laws"), which
              compliance includes, but is not limited to, (1) compliance with
              all standards, schedules and timetables therein, and (2) the
              possession of all permits, licenses, approvals and other
              authorizations required under the Environmental Laws with respect
              to the operation of the business, property and assets of the
              Issuer or any of its Subsidiaries or any such Person, and
              compliance with the terms and conditions thereof and (3) any
              federal, state, local or foreign approvals required pursuant to
              any Environmental Laws that pertain or relate to the transactions
              contemplated by this Agreement;

                     (ii)   each of the Issuer and its Subsidiaries has not
              received any notice or claim (written or oral), whether from a
              governmental authority, citizens group, employee or otherwise,
              that alleges that it is in violation of any Environmental Law;
              each of the Issuer and its Subsidiaries has no liability under
              any Environmental Law; and, to the best knowledge of each of the
              Issuer and its Subsidiaries, there are no past or present
              actions, activities, circumstances, conditions, events or
              incidents that may be expected to prevent or interfere with full
              compliance by each of the Issuer and its Subsidiaries (or any
              Person for whom the Issuer or any of its Subsidiaries is or may
              be responsible by law or contract) with applicable Environmental
              Laws in the future;

                     (iii)  there is no claim, action, cause of action,
              investigation or notice (written or oral) by any Person alleging
              potential or actual liability (including, without limitation,
              potential or actual liability for investigating costs, clean up
              costs, governmental response costs, natural resources damages,
              property damages, personal injuries or penalties) arising out of,
              based upon, resulting from or relating to or under any
              Environmental Law, including, without limitation, any such
              liability relating to the presence, or release into the
              environment of any Material of Environmental Concern (as defined
              below), or circumstances forming the basis of any violation, or
              alleged violation, of any Environmental Law (collectively,
              "Environmental Liability") pending or, to the best knowledge of
              the Issuer, threatened against the Issuer or any of its
              Subsidiaries;

                     (iv)   there are no past or present actions, activities,
              circumstances, conditions, events or incidents, including,
              without limitation, the release, emission, discharge, presence or
              disposal of any pollutants, contaminants, chemicals, industrial,
              toxic or hazardous wastes, substances or constituents, petroleum
              and petroleum products (or any by-product or constituent
              thereof), asbestos or asbestos-containing materials, or
              polychlorinated biphenyls (collectively, "Materials of
              Environmental Concern"), that could reasonably be expected to
              form the basis of any Environmental Liability against the Issuer
              or any of its Subsidiaries;

                     (v)    no real property or facility owned, used, operated,
              leased, managed or controlled by the Issuer or any of its
              Subsidiaries, or, to the best knowledge of each of the Issuer and
              its Subsidiaries, any predecessor in interest for which the
              Issuer or any of its Subsidiaries could be responsible, is listed
              or proposed for listing on the National Priorities List or the
              Comprehensive Environmental Response, Compensation, and Liability
              Information System pursuant to the Comprehensive Environmental
              Response, Compensation, and Liability Act, as amended, or on any
              comparable state or local lists established pursuant to any
              Environmental Law;

                     (vi)   there have been no releases (including, without
              limitation, any past or present releasing, spilling, leaking,
              pumping, pouring, emitting, emptying, discharging, injecting,
              escaping, leaching, disposing or dumping, on-site or off-site) of
              Materials of Environmental Concern by the Issuer or any of its
              Subsidiaries or, to the best knowledge of each of the Issuer and
              its Subsidiaries, any predecessor in interest, for which the
              Issuer or any of its Subsidiaries could reasonably be expected to
              incur liability under or pursuant to any Environmental Law, at,
              on, under, from or into any facility or real property owned,
              operated, leased, managed or controlled by the Issuer or any of
              its Subsidiaries, and each of the Issuer and its Subsidiaries has
              not incurred or reasonably could be expected to incur any
              Environmental Liability for contamination at, on, under, from or
              into any on-site or off-site locations where the Issuer or any of
              its Subsidiaries has stored, disposed or arranged for the
              disposal of Materials of Environmental Concern;

                     (vii)  the condition of all underground storage tanks or
              other underground storage receptacles, or related piping, that
              are located on a facility or property owned, operated, leased,
              managed or controlled by the Issuer or any of its Subsidiaries is

       of the Securities Act or Section 20 of the Exchange Act) the Purchaser
       (any of such persons being hereinafter referenced as a "controlling
       person"), and the respective officers, directors, partners, employees,
       representatives and agents of the Purchaser and any such controlling
       person (collectively, the "Indemnified Parties"), to the fullest extent
       lawful, from and against any and all losses, claims, damages,
       liabilities, costs (including, without limitation, costs of preparation
       and reasonable attorneys' fees) and expenses (including, without
       limitation, costs and expenses incurred in connection with
       investigating, preparing, pursuing or defending against any of the
       foregoing) (collectively, "Losses"), as incurred, directly or indirectly
       caused by, related to, based upon, arising out of or in connection with
       any untrue statement or alleged untrue statement of a material fact
       contained in the Preliminary Offering Circular or the Offering Circular
       (or any amendment or supplement thereto), or any omission or alleged
       omission to state therein a material fact required to be stated therein
       or necessary to make the statements therein, in the light of the
       circumstances under which they were made, not misleading, except insofar
       as any such Loss arises out of or is based upon any untrue statement or
       omission or alleged untrue statement or omission that has been made
       therein or omitted therefrom in reliance upon and in conformity with the
       information provided in writing to the Issuer by or on behalf of the
       Purchaser, expressly for use in the Registration Statement or the
       Offering Circular, and the TransAmerican Entities agree that the only
       such information provided in writing by or on behalf of the Purchaser,
       expressly for use in the Preliminary Offering Circular or the Offering
       Circular is that information contained in the section of the Preliminary
       Offering Circular or the Offering Circular entitled "Plan of
       Distribution" and the last paragraph of text on the cover page of the
       Preliminary Offering Circular and the Offering Circular; provided, that
       the indemnity agreement contained in this Section 8(a) with respect to
       any Preliminary Offering Circular or amended Preliminary Offering
       Circular shall not inure to the benefit of the Indemnified Party from
       whom the person asserting any such loss, expense, liability or claim
       purchased the Securities which is the subject thereof, if the Offering
       Circular corrected any such alleged untrue statement or omission and if
       the Purchaser failed to deliver or have delivered on its behalf a copy
       of the Offering Circular, excluding any documents incorporated by
       reference, to such person at or prior to the written confirmation of the
       sale of Securities to such person, provided that the Issuer has
       delivered the Offering Circular to the Purchaser in sufficient quantity
       not less than one full business day prior to the written confirmation of
       the sale to the person asserting such claim.  Notwithstanding any
       provision hereof to the contrary, the liability of each of TARC and
       TransTexas pursuant to this Section 8(a) shall be limited to the amount
       of proceeds of the Offering received directly or indirectly by such
       corporation, including without limitation pursuant to the transactions
       contemplated hereby or by the Offering Circular.

              If any action is brought against the Purchaser or any of its
       affiliates or any of their respective officers, shareholders, counsel,
       agents, employees, directors or any person who controls the Purchaser
       (as described above) in respect of which indemnity may be sought against
       any of the TransAmerican Entities pursuant to the foregoing paragraph,
       the Purchaser shall promptly notify the TransAmerican Entities in
       writing of the institution of such action (provided, that the failure to
       give such notice shall not relieve any of the TransAmerican Entities of
       any liability which it may have pursuant to this Agreement, unless it
       shall have been determined by a court of competent jurisdiction by final
       judgment that such failure has resulted in the forfeiture of substantive
       rights or defenses by the indemnifying party) and the TransAmerican
       Entities shall assume the defense of such action, including the
       employment of counsel and payment of reasonable expenses.  The Purchaser
       or such affiliate, officer, shareholder, counsel, agent, employee,
       director or person who controls the Purchaser (as described) shall have
       the right to employ its or their own counsel in any such case and to
       participate in the defense thereof, but the fees and expenses of such
       counsel shall be at the expense of the Purchaser or such other person
       unless: (i) the TransAmerican Entities shall have failed to assume the
       defense of such action or the TransAmerican Entities shall have failed
       to employ counsel reasonably satisfactory to the Purchaser or such other
       person in any such action; or (ii) such indemnified party shall have
       been advised by counsel that there may be one or more defenses available
       to it that are different from or additional to those available to the
       TransAmerican Entities (in which case, if such indemnified party
       notifies the TransAmerican Entities in writing that it elects to employ
       separate counsel at the expense of the TransAmerican Entities, the
       TransAmerican Entities shall not have the right to assume the defense of
       such action on behalf of such indemnified party), in any of which events
       such fees and expenses shall be borne by the TransAmerican Entities and
       paid as incurred; provided, that the TransAmerican Entities shall be
       responsible for the fees and expenses of only one counsel (in addition
       to any reasonably required local counsel) for all indemnified parties
       hereunder.  Anything in this paragraph to the contrary notwithstanding,
       the TransAmerican Entities shall not be liable for any settlement of any
       such claim or action effected without its written consent, which consent
       shall not be unreasonably withheld.

              (b)    The Purchaser agrees to indemnify, defend and hold
       harmless each of the TransAmerican Entities, their respective affiliates
       and their respective directors, officers, shareholders, counsel, agents
       and employees and any person who controls any of the TransAmerican
       Entities or any of its affiliates within the meaning of Section 15 of
       the Act or Section 20 of the Exchange Act from and against any Losses
       incurred insofar as such Loss is caused by, related to, based upon,
       arises out of or is in connection with any untrue statement or omission
       or alleged untrue statement or omission which has been made in or
       omitted from the Preliminary Offering Circular or the Offering Circular
       in reliance upon and in conformity with the information relating to the
       Purchaser furnished in writing by or on behalf of the Purchaser to the
       Issuer expressly for use in the Preliminary Offering Circular or the
       Offering Circular.  The TransAmerican Entities agree that the only
       information provided in writing by or on behalf of the Purchaser to the
       Issuer, expressly for use in the Preliminary Offering Circular or the
       Offering Circular, is that information contained in the section of the
       Preliminary Offering Circular or the Offering Circular entitled "Plan of
       Distribution" and the last paragraph of text on the cover page of the
       Preliminary Offering Circular or the Offering Circular.

              If any action is brought against any of the TransAmerican
       Entities or any of its affiliates or any other such person in respect of
       which indemnity may be sought against the Purchaser





                                       22
<PAGE>   23
       pursuant to the foregoing paragraph, the TransAmerican Entities, such
       affiliate or such other person shall promptly notify the Purchaser in
       writing of the institution of such action (provided, that the failure to
       give such notice shall not relieve the Purchaser of any liability which
       it may have pursuant to this Agreement, unless it shall have been
       determined by a court of competent jurisdiction by final judgment that
       such failure has resulted in the forfeiture of substantive rights or
       defenses by the indemnifying party) and the Purchaser shall assume the
       defense of such action, including the employment of counsel and payment
       of reasonable expenses.  The TransAmerican Entities, such affiliate or
       such other person shall have the right to employ its or their own
       counsel in any such case and to participate in the defense thereof, but
       the fees and expenses of such counsel shall be at the expense of the
       TransAmerican Entities, such affiliate or such other person unless: (i)
       the Purchaser shall have failed to assume the defense of the action or
       shall have failed to employ counsel reasonably satisfactory to the
       TransAmerican Entities or such other person in any such action; or (ii)
       such indemnified party shall have been advised by counsel that there may
       be one or more defenses available to it that are different from or
       additional to those available to the Purchaser (in which case, if such
       indemnified party notifies the Purchaser in writing that it elects to
       employ separate counsel at the expense of the Purchaser, the Purchaser
       shall not have the right to assume the defense of such action on behalf
       of the indemnified party), in any of which events such fees and expenses
       shall be borne by the Purchaser and paid as incurred; provided, that the
       Purchaser shall be responsible for the fees and expenses of only one
       counsel (in addition to any reasonably required local counsel) for all
       indemnified parties.  Anything in this paragraph to the contrary
       notwithstanding, the Purchaser shall not be liable for any settlement of
       any such claim or action effected without the written consent of the
       Purchaser, which consent shall not be unreasonably withheld.

              The Issuer shall notify the Purchaser promptly of the
       institution, threat or assertion of any Proceeding of which the Issuer
       or any Subsidiary is aware in connection with the matters addressed by
       this Agreement which involves the Issuer, any of the Subsidiaries or any
       of the indemnified parties.

              (c)    If the indemnification provided for in this Section 8 is
       unavailable to an indemnified party or is insufficient to hold such
       indemnified party harmless for any Losses in respect of which this
       Section 8 would otherwise apply by its terms (other than by reason of
       exceptions provided in this Section 8), then each indemnifying party, in
       lieu of indemnifying such indemnified party, shall contribute to the
       amount paid or payable by such indemnified party as a result of such
       Losses (i) in such proportion as is appropriate to reflect the relative
       benefits received by the TransAmerican Entities, on the one hand, and
       the Purchaser, on the other hand, from the offering of the Series A
       Notes or (ii) if the allocation provided by clause (i) above is not
       permitted by applicable law, in such proportion as is appropriate to
       reflect not only the relative benefits referenced in clause (i) above
       but also the relative fault of the TransAmerican Entities, on the one
       hand, and the Purchaser, on the other hand, in connection with the
       actions, statements or omissions that resulted in such Losses, as well
       as any other relevant equitable considerations.  The relative benefits
       received by the TransAmerican Entities, on the one hand, and the
       Purchaser, on the other





                                       23
<PAGE>   24
       hand, shall be deemed to be in the same proportion as the total net
       proceeds from the offering (before deducting expenses) received by the
       TransAmerican Entities, and the total discounts and commissions received
       by the Purchaser, bear to the total price of the Series A Notes in
       Exempt Resales in each case as set forth in the table on the cover page
       of the Offering Circular.  The relative fault of the TransAmerican
       Entities, on the one hand, and the Purchaser, on the other hand, shall
       be determined by reference to, among other things, whether any untrue or
       alleged untrue statement of a material fact or omission or alleged
       omission to state a material fact relates to information supplied by the
       TransAmerican Entities, on the one hand, or the Purchaser, on the other
       hand, and the parties' relative intent, knowledge, access to information
       and opportunity to correct or prevent such statement or omission.  The
       amount paid or payable by an indemnified party as a result of any Losses
       shall be deemed to include any legal or other fees or expenses incurred
       by such party in connection with any Proceeding, to the extent such
       party would have been indemnified for such fees or expenses if the
       indemnification provided for in this Section 8 was available to such
       party.

                     Each party hereto agrees that it would not be just and
       equitable if contribution pursuant to this Section 8(c) were determined
       by pro rata allocation or by any other method of allocation which does
       not take account of the equitable considerations referenced in the
       immediately preceding paragraph. Notwithstanding the provisions of this
       Section 8(c), the Purchaser shall not be required to contribute, in the
       aggregate, any amount in excess of the amount by which the total
       discounts and commissions received by it with respect to the Series A
       Notes exceeds the amount of any damages that the Purchaser has otherwise
       been required to pay by reason of such untrue or alleged untrue
       statement or omission or alleged omission.  No person guilty of
       fraudulent misrepresentation (within the meaning of Section 11(f) of the
       Securities Act) shall be entitled to contribution from any person who
       was not guilty of such fraudulent misrepresentation.

              (d)    The indemnity and contribution agreements contained in
       this Section 8 are in addition to any liability that the TransAmerican
       Entities or the Purchaser may otherwise have to the indemnified parties.

       9.     Conditions.

              (a)    The obligation of the Purchaser to purchase the Series A
       Notes under this Agreement is subject to the satisfaction or waiver of
       each of the following conditions:

              than representations and warranties with a materiality qualifier,
              which shall be true and correct as written) at and as of the
              Closing Date after giving effect to the Transactions with the
              same force and effect as if made on and as of such date.  On or
              prior to the Closing Date, each of the TransAmerican Entities
              and, to the knowledge of each of the TransAmerican Entities after
              due inquiry, each other party to the Documents (other than the
              Purchaser) shall have performed or complied in all material
              respects with all of the agreements and satisfied in all material
              respects all conditions on their respective parts to be
              performed, complied with or satisfied pursuant to the Documents.

                     (ii)   The Offering Circular shall have been printed and
              copies made available to the Purchaser not later than 12:00 noon,

              of this Agreement or at such later date and time as the Purchaser
              may approve.

              consummation of any of the Transactions; and no stop order
              suspending the qualification or exemption from qualification of
              any of the Series A Notes in any jurisdiction shall have been
              issued and no Proceeding for that purpose shall have been
              commenced or be pending or contemplated.

              the Closing Date, prevent the consummation of any of the
              Transactions.  No Proceeding shall be pending or threatened other
              than Proceedings that (A) if adversely determined could not,
              singly or in the aggregate, adversely affect the issuance or
              marketability of the Series A Notes and (B) could not reasonably
              be expected to have a Material Adverse Effect.

                     (v)    Since the date as of which information is given in
              the Offering Circular, there shall not have been any Material

       prospects, operations, earnings, assets, liabilities or condition

       whether arising in the ordinary course of business, that could, in the
       Purchaser's judgment, (i) make it impracticable or inadvisable to

       calamity, crisis or material adverse change in the economic conditions
       in or in the financial markets of the United States of America or
       elsewhere make it, in the Purchaser's judgment, impracticable or
       inadvisable to market or proceed with the offering or delivery of the
       Series A Notes on the terms and in the manner contemplated in the
       Offering Circular or to enforce contracts for the sale of any of the
       Series A Notes;

       adversely affect, the properties, business, prospects, operations,
       earnings, assets, liabilities or condition (financial or otherwise) of
       the Issuer or any Subsidiary;

              (f)    any securities of any TransAmerican Entity shall have been
       downgraded or placed on any "watch list" for possible downgrading by any

              (g)    the declaration of a banking moratorium by any
       Governmental Authority or the taking of any Governmental Authority after
       the date hereof in respect of its monetary or fiscal affairs that in the
       Purchaser's opinion could have a material adverse effect on the
       financial markets in the United States of America or elsewhere.

              The indemnities and contribution and expense reimbursement
provisions and other agreements, representations and warranties of the
TransAmerican Entities and the Purchaser set forth in or made pursuant to this
Agreement shall remain operative and in full force and effect, and will
survive, regardless of (i) any investigation, or statement as to the results
thereof, made by or on behalf of the Purchaser, (ii) acceptance of the Notes,
and payment for them hereunder, and (iii) any termination of this Agreement.
Without limiting the foregoing, notwithstanding any termination of this
Agreement, each of the TransAmerican Entities shall be liable (i) for all
expenses that it has agreed to pay pursuant to Section 5(g) hereof, and (ii)

such Series A Notes are not made within 36 hours after such default, this
Agreement shall terminate without liability on the part of the Issuer, except
as otherwise provided in Section 10 hereof.  Nothing herein shall relieve the
Purchaser from liability for its default.

       have the right to take action against the Issuer to enforce, and obtain
       damages for any breach of, those covenants.

       SUCH MAILING.  NOTHING HEREIN SHALL AFFECT THE RIGHT OF THE PURCHASER TO

       together shall constitute one and the same instrument.

              (e)    The headings in this Agreement are for convenience of
       reference only and shall not limit or otherwise affect the meaning
       hereof.

              (f)    If any term, provision, covenant or restriction of this
       Agreement is held by a court of competent jurisdiction to be invalid,
       illegal, void or unenforceable, the remainder of the terms, provisions,
       covenants and restrictions set forth herein shall remain in full force
       and effect and shall in no way be affected, impaired or invalidated, and
       the parties hereto shall use their best efforts to find and employ an
       alternative means to achieve the same or substantially the same result
       as that contemplated by such term, provision, covenant or restriction.
       It is hereby stipulated and declared to be the intention of the parties
       that they would have executed the remaining terms, provisions, covenants
       and restrictions without including any of such that may be hereafter
       declared invalid, illegal, void or unenforceable.

              (g)    This Agreement may be amended, modified or supplemented,
       and waivers or consents to departures from the provisions hereof may be
       given, provided that the same are in writing and signed by each of the
       signatories hereto.

              (h)    The indemnities and contribution and expense reimbursement
       provisions set forth in or made pursuant to this Agreement shall remain
       operative and in full force and effect, and will survive delivery and
       payment for the Series A Notes, regardless of (i) any investigation, or
       statement as to the results thereof, made by or on behalf of any party
       hereto, (ii) acceptance of the Series A Notes, and payment for them
       hereunder, and (iii) any termination of this Agreement.

     The undersigned hereby acknowledges receipt and review of the Prospectus
dated                , 1997 (the "Prospectus") of TransAmerican Energy
Corporation, a Delaware corporation (the "Company") and this Letter of
Transmittal (the "Letter of Transmittal"), which together describe the Company's
offer (the "Exchange Offer") to exchange its 11 1/2% Series B Senior Secured
Notes due 2002 and 13% Series B Senior Secured Discount Notes due 2002 (the
"Exchange Notes"), which have been registered under the Securities Act of 1933,
as amended (the "Securities Act"), pursuant to a Registration Statement of which
the Prospectus is a part, for a like principal amount of its issued and
outstanding 11 1/2% Senior Secured Notes due 2002 and 13% Senior Secured
Discount Notes due 2002 (the "Outstanding Notes"), respectively. Capitalized
terms used but not defined herein have the respective meaning given to them in
the Prospectus.
 
     The Company reserves the right, at any time or from time to time, to extend
the Exchange Offer at its discretion, in which event the term "Expiration Date"
shall mean the latest date to which the Exchange Offer is extended. The Company
shall notify the holders of the Outstanding Notes of any extension by
announcement thereof, prior to 9:00 a.m., New York City time, on the next
business day after the previously scheduled Expiration Date.
 
     This Letter of Transmittal is to be used by a holder of Outstanding Notes
if original Outstanding Notes, if available, are to be forwarded herewith or an
Agent's Message is to be used if delivery of Outstanding Notes is to be made by

procedures set forth in the Prospectus under the caption "The Exchange Offer --
Procedures for Tendering." Holders of Outstanding Notes whose Outstanding Notes

Outstanding Notes according to the guaranteed delivery procedures set forth in
the Prospectus under the caption "The Exchange Offer -- Guaranteed Delivery
Procedures." See Instructions 1 and 2. Delivery of documents to the Book-Entry
Transfer Facility does not constitute delivery to the Exchange Agent.

     The term "holder" with respect to the Exchange Offer means any person in
whose name Outstanding Notes are registered on the books of the Company or any
other person who has obtained a properly completed bond power from the

              PLEASE READ THE ACCOMPANYING INSTRUCTIONS CAREFULLY
 
Ladies and Gentlemen:
 
     Subject to the terms and conditions of the Exchange Offer, the undersigned
hereby tenders to the Company for exchange the principal amount of Outstanding
Notes indicated above. Subject to and effective upon the acceptance for exchange
of the principal amount of Outstanding Notes tendered in accordance with this
Letter of Transmittal, the undersigned hereby exchanges, assigns and transfers
to the Company all right, title and interest in and to the Outstanding Notes
tendered for exchange hereby. The undersigned hereby irrevocably constitutes and
appoints the Exchange Agent, the agent and attorney-in-fact of the undersigned
(with full knowledge that the Exchange Agent also acts as the agent of the
Company in connection with the Exchange Offer) with respect to the tendered
Outstanding Notes with full power of substitution to (i) deliver such
Outstanding Notes, or transfer ownership of such Outstanding Notes on the
account books maintained by the Book-Entry Transfer Facility, to the Company and
deliver all accompanying evidences of transfer and authenticity, and (ii)
present such Outstanding Notes for transfer on the books of the Company and
receive all benefits and otherwise exercise all rights of beneficial ownership
of such Outstanding Notes, all in accordance with the terms of the Exchange
Offer. The power of attorney granted in this paragraph shall be deemed to be
irrevocable and coupled with an interest.
 
     The undersigned hereby represents and warrants that the undersigned has
full power and authority to tender, exchange, assign and transfer the
Outstanding Notes tendered hereby and to acquire the Exchange Notes issuable
upon the exchange of such tendered Outstanding Notes, and that the Company will
acquire good and unencumbered title thereto, free and clear of all liens,
restrictions, charges and encumbrances and not subject to any adverse claim,
when the same are accepted for exchange by the Company.
 
     The undersigned acknowledge(s) that this Exchange Offer is being made in
reliance upon interpretations contained in no-action letters issued to third
parties by the staff of the Securities and Exchange Commission (the "SEC"),
including Exxon Capital Holdings Corporation, SEC No-Action Letter (available
April 13, 1989), Morgan Stanley & Co. Inc., SEC No-Action Letter (available June
5, 1991) (the "Morgan Stanley Letter") and Mary Kay Cosmetics, Inc., SEC
No-Action Letter (available June 5, 1991), that the Exchange Notes issued in
exchange for the Outstanding Notes pursuant to the Exchange Offer may be offered
for resale, resold and otherwise transferred by holders thereof (other than (i)
a broker-dealer who purchased Outstanding Notes exchanged for such Exchange
Notes directly from the Company to resell pursuant to Rule 144A or any other
available exemption under the Securities Act and (ii) an affiliate of the
Company), without compliance with the registration and prospectus delivery
provisions of the Securities Act, provided that such Exchange Notes are acquired
in the ordinary course of such holders' business and such holders are not
participating in, and have no arrangement with any person to participate in, the
distribution of such Exchange Notes. The undersigned specifically represent(s)
to the Company that (i) any Exchange Notes acquired in exchange for Outstanding
Notes tendered hereby are being acquired in the ordinary course of business of
the person receiving such Exchange Notes, whether or not the undersigned, (ii)
the undersigned is not participating in, and has no arrangement with any person
to participate in, the distribution of Exchange Notes, and (iii) neither the
undersigned nor any such other person is an "affiliate" (as defined in Rule 405
under the Securities Act) of the Company or a broker-dealer tendering
Outstanding Notes acquired directly from the Company for its own account.
 
     If the undersigned or the person receiving the Exchange Notes is a
broker-dealer that is receiving Exchange Notes for its own account pursuant to
the Exchange Offer, the undersigned acknowledges that it or such other person
will deliver a prospectus in connection with any resale of such Exchange Notes.
The undersigned acknowledges that if the undersigned is participating in the
Exchange Offer for the purpose of distributing the Exchange Notes (i) the
undersigned cannot rely on the position of the staff of the SEC in the Morgan
Stanley Letter and similar SEC no-action letters, and, in the absence of an
exemption therefrom, must comply with the registration and prospectus delivery
requirements of the Securities Act in connection with a secondary resale
transaction of the Exchange Notes, in which case the registration statement must
contain the selling security holder information required by Item 507 or Item
508, as applicable, of Regulation S-K of the SEC, and (ii) a broker-dealer that
delivers such a prospectus to purchasers in connection with such resales will be
subject to certain of the civil liability provisions under the Securities Act
and will be bound by the provisions of the Registration Rights Agreement
(including certain indemnification rights and obligations).
 
     The undersigned will, upon request, execute and deliver any additional
documents deemed by the Exchange Agent or the Company to be necessary or
desirable to complete the exchange, assignment and transfer of the Outstanding
Notes tendered hereby, including the transfer of such Outstanding Notes on the
account books maintained by the Book-Entry Transfer Facility.
 
     For purposes of the Exchange Offer, the Company shall be deemed to have
accepted for exchange validly tendered Outstanding Notes when, as and if the
Company gives oral or written notice thereof to the Exchange Agent. Any tendered
Outstanding Notes that are not accepted for exchange pursuant to the Exchange
Offer for any reason will be returned, without expense, to the undersigned at
the address shown below or at a different address as may be indicated herein
under "Special Delivery Instructions" as promptly as practicable after the
Expiration Date.
<PAGE>   5
 
     All authority conferred or agreed to be conferred by this Letter of
Transmittal shall survive the death, incapacity or dissolution of the
undersigned, and every obligation of the undersigned under this Letter of
Transmittal shall be binding upon the undersigned's heirs, personal
representatives, successors and assigns.
 
     The undersigned acknowledges that the Company's acceptance of properly
tendered Outstanding Notes pursuant to the procedures described under the
caption "The Exchange Offer -- Procedures for Tendering" in the Prospectus and
in the instructions hereto will constitute a binding agreement between the
undersigned and the Company upon the terms and subject to the conditions of the
Exchange Offer. The undersigned further acknowledges its obligations under the
Registration Rights Agreement as applicable to the Exchange Offer and the
Registration Statement of which the Prospectus is a part.
 
     Unless otherwise indicated under "Special Issuance Instructions," please
issue the Exchange Notes issued in exchange for the Outstanding Notes accepted
for exchange and return any Outstanding Notes not tendered or not exchanged, in
the name(s) of the undersigned. Similarly, unless otherwise indicated under
"Special Delivery Instructions," please mail or deliver the Exchange Notes
issued in exchange for the Outstanding Notes accepted for exchange and any
Outstanding Notes not tendered or not exchanged (and accompanying documents, as
appropriate) to the undersigned at the address shown below the undersigned's
signature(s). In the event that both the "Special Issuance Instructions" and
"Special Delivery Instructions" are completed, please issue the Exchange Notes
issued in exchange for the Outstanding Notes accepted for exchange in the
name(s) of, and return any Outstanding Notes not tendered or not exchanged to,
the person(s) so indicated. The undersigned recognizes that the Company has no
obligation pursuant to the "Special Issuance Instructions" and "Special Delivery
Instructions" to transfer any Outstanding Notes from the name of the registered
holder(s) thereof if the Company does not accept for exchange any of the
Outstanding Notes so tendered for exchange.

York Stock Exchange trading days after the Expiration Date; and (iii) the
certificates for all physically tendered shares of Outstanding Notes, in proper
form for transfer (or a Book-Entry Confirmation, as the case may be) and all
other documents required hereby are received by the Exchange Agent within three
New York Stock Exchange trading days after the Expiration Date.
 
     Any holder of Outstanding Notes who wishes to tender Outstanding Notes
pursuant to the guaranteed delivery procedures described above must ensure that
the Exchange Agent receives the Notice of Guaranteed Delivery prior to 5:00
p.m., New York City time, on the Expiration Date. Upon request of the Exchange
Agent, a Notice of Guaranteed Delivery will be sent to holders who wish to

set forth above.
 
     See "The Exchange Offer -- Guaranteed Delivery Procedures" section of the
Prospectus.
 
     3. Tender of Holder. Only a holder of Outstanding Notes may tender such
Outstanding Notes in the Exchange Offer. Any beneficial holder of Outstanding
Notes who is not the registered holder and who wishes to tender should arrange
with the registered holder to execute and deliver this Letter of Transmittal on
his behalf or must, prior to completing and executing this Letter of Transmittal
and delivering his Outstanding Notes, either make appropriate arrangements to
register ownership of the Outstanding Notes in such holder's name or obtain a
properly completed bond power from the registered holder.
 
     4. Partial Tenders. Tenders of Outstanding Notes will be accepted only in
integral multiples of $1,000. If less than the entire principal amount of any
Outstanding Notes is tendered, the tendering holder should fill in the principal
amount tendered in the third column of the box entitled "Description of
Outstanding Notes Tendered" above. The entire principal amount of Outstanding
Notes delivered to the Exchange Agent will be deemed to have been tendered
unless otherwise indicated. If the entire principal amount of all Outstanding
Notes is not tendered, then Outstanding Notes for the principal amount of
Outstanding Notes not tendered and Exchange Notes issued in exchange for any
Outstanding Notes accepted will be sent to the holder at his or her registered
address, unless a different address is provided in the appropriate box on this
Letter of Transmittal, promptly after the Outstanding Notes are accepted for
exchange.
 
     5. Signatures on this Letter of Transmittal; Bond Powers and Endorsements;
Medallion Guarantee of Signatures. If this Letter of Transmittal (or facsimile
hereof) is signed by the record holder(s) of the Outstanding Notes tendered
hereby, the signature must correspond with the name(s) as written on the face of
the Outstanding Notes without alteration, enlargement or any change whatsoever.
If this Letter of Transmittal (or facsimile hereof) is signed by a participant
in the Book-Entry Transfer Facility, the signature must correspond with the name

Notes.
<PAGE>   9
 
     If this Letter of Transmittal (or facsimile hereof) is signed by the
registered holder or holders of Outstanding Notes listed and tendered hereby and
the Exchange Notes issued in exchange therefor are to be issued (or any
untendered principal amount of Outstanding Notes is to be reissued) to the
registered holder, the holder need not and should not endorse any tendered
Outstanding Notes, nor provide a separate bond power. In any other case, such
holder must either properly endorse the Outstanding Notes tendered or transmit a
properly completed separate bond power with this Letter of Transmittal, with the
signatures on the endorsement or bond power guaranteed by an Eligible
Institution.
 
     If this Letter of Transmittal (or facsimile hereof) is signed by a person
other than the registered holder or holders of any Outstanding Notes listed,
such Outstanding Notes must be endorsed or accompanied by appropriate bond
powers, in each case signed as the name of the registered holder or holders
appears on the Outstanding Notes.
 
     If this Letter of Transmittal (or facsimile hereof) or any Outstanding
Notes or bond powers are signed by trustees, executors, administrators,
guardians, attorneys-in-fact, officers of corporations or others acting in a
fiduciary or representative capacity, such persons should so indicate when
signing, and, unless waived by the Company, evidence satisfactory to the Company
of their authority to act must be submitted with this Letter of Transmittal.
 
     Endorsements on Outstanding Notes or signatures on bond powers required by
this Instruction 5 must be guaranteed by an Eligible Institution.
 
     No signature guarantee is required if (i) this Letter of Transmittal (or
facsimile hereof) is signed by the registered holder(s) of the Outstanding Notes
tendered herein (or by a participant in the Book-Entry Transfer Facility whose
name appears on a security position listing as the owner of the tendered
Outstanding Notes) and the Exchange Notes are to be issued directly to such
registered holder(s) (or, if signed by a participant in the Book-Entry Transfer
Facility, deposited to such participant's account at such Book-Entry Transfer
Facility) and neither the box entitled "Special Delivery Instructions" nor the
box entitled "Special Registration Instructions" has been completed, or (ii)
such Outstanding Notes are tendered for the account of an Eligible Institution.
In all other cases, all signatures on this Letter of Transmittal (or facsimile
hereof) must be guaranteed by an Eligible Institution.
 
     6. Special Registration and Delivery Instructions. Tendering holders should
indicate, in the applicable box or boxes, the name and address (or account at
the Book-Entry Transfer Facility) to which Exchange Notes or substitute
Outstanding Notes for principal amounts not tendered or not accepted for
exchange are to be issued or sent, if different from the name and address of the
person signing this Letter of Transmittal. In the case of issuance in a
different name, the taxpayer identification or social security number of the
person named must also be indicated.
 
     7. Transfer Taxes. The Company will pay all transfer taxes, if any,
applicable to the exchange of Outstanding Notes pursuant to the Exchange Offer.
If, however, Exchange Notes or Outstanding Notes for principal amounts not
tendered or accepted for exchange are to be delivered to, or are to be
registered or issued in the name of, any person other than the registered holder
of the Outstanding Notes tendered hereby, or if tendered Outstanding Notes are
registered in the name of any person other than the person signing this Letter
of Transmittal, or if a transfer tax is imposed for any reason other than the
exchange of Outstanding Notes pursuant to the Exchange Offer, then the amount of
any such transfer taxes (whether imposed on the registered holder or any other
persons) will be payable by the tendering holder. If satisfactory evidence of
payment of such taxes or exemption therefrom is not submitted with this Letter
of Transmittal, the amount of such transfer taxes will be billed directly to
such tendering holder.
 
     EXCEPT AS PROVIDED IN THIS INSTRUCTION 7, IT WILL NOT BE NECESSARY FOR
TRANSFER TAX STAMPS TO BE AFFIXED TO THE OUTSTANDING NOTES LISTED IN THIS LETTER
OF TRANSMITTAL.
 
     8. Tax Identification Number. Federal income tax law requires that a holder
of any Outstanding Notes which are accepted for exchange must provide the
Company (as payor) with its correct taxpayer identification number ("TIN"),
which, in the case of a holder who is an individual is his or her social
security number. If the Company is not provided with the correct TIN, the holder
may be subject to a $50 penalty imposed by Internal Revenue Service. (If
withholding results in an over-payment of taxes, a refund may be obtained).
Certain holders (including, among others, all corporations and certain foreign
individuals) are not subject to these backup withholding and reporting
requirements. See the enclosed "Guidelines for Certification of Taxpayer
Identification Number on Substitute Form W-9" for additional instructions.
 
     To prevent backup withholding, each tendering holder must provide such
holder's correct TIN by completing the Substitute Form W-9 set forth herein,
certifying that the TIN provided is correct (or that such holder is awaiting a
TIN), and that (i) the holder has not been notified by the Internal Revenue
Service that such holder is subject to backup withholding as a result of failure
to report all interest or dividends or (ii) the Internal Revenue Service has
notified the holder that such holder is no longer subject to backup withholding.
If the Outstanding Notes are registered in more than one name or are not in the
name of the actual owner, see the enclosed "Guidelines for Certification of
Taxpayer Identification Number of Substitute Form W-9" for information on which
TIN to report.
 
     The Company reserves the right in its sole discretion to take whatever
steps are necessary to comply with the Company's obligations regarding backup
withholding.
<PAGE>   10
 
     9.  Validity of Tenders. All questions as to the validity, form,
eligibility (including time of receipt), acceptance and withdrawal of tendered
Outstanding Notes will be determined by the Company in its sole discretion,
which determination will be final and binding. The Company reserves the absolute
right to reject any and all Outstanding Notes not properly tendered or any
Outstanding Notes the Company's acceptance of which would, in the opinion of the
Company or its counsel, be unlawful. The Company also reserves the absolute
right to waive any conditions of the Exchange Offer or defects or irregularities
in tenders as to particular Outstanding Notes. The Company's interpretation of
the terms and conditions of the Exchange Offer (including this Letter of
Transmittal and the instructions hereto) shall be final and binding on all
parties. Unless waived, any defects or irregularities in connection with tenders
of Outstanding Notes must be cured within such time as the Company shall
determine. Neither the Company, the Exchange Agent nor any person shall be under
any duty to give notification of defects or irregularities with regard to
tenders of Outstanding Notes nor shall any of them incur any liability for
failure to give such notification.
 
     10. Waiver of Conditions. The Company reserves the absolute right to waive,
in whole or part, any of the conditions to the Exchange Offer set forth in the
Prospectus.
 
     11. No Conditional Tender. No alternative, conditional, irregular, or
contingent tender of Outstanding Notes on transmittal of this Letter of
Transmittal will be accepted.
 
     12. Mutilated, Lost, Stolen or Destroyed Outstanding Notes. Any holder
whose Outstanding Notes have been mutilated, lost, stolen or destroyed should
contact the Exchange Agent at the address indicated above for further
instructions.
 
     13. Requests for Assistance or Additional Copies. Requests for assistance
or for additional copies of the Prospectus or this Letter of Transmittal may be
directed to the Exchange Agent at the address or telephone number set forth on
the cover page of this Letter of Transmittal. Holders may also contact their
broker, dealer, commercial bank, trust company or other nominee for assistance
concerning the Exchange Offer.
 
     14. Withdrawal. Tenders may be withdrawn only pursuant to the limited
withdrawal rights set forth in the Prospectus under the caption "The Exchange
Offer -- Withdrawal of Tenders."
 
IMPORTANT:  THIS LETTER OF TRANSMITTAL OR A MANUALLY SIGNED FACSIMILE HEREOF
(TOGETHER WITH THE OUTSTANDING NOTES DELIVERED BY BOOK-ENTRY TRANSFER OR IN
ORIGINAL HARD COPY FORM) MUST BE RECEIVED BY THE EXCHANGE AGENT, OR THE NOTICE
OF GUARANTEED DELIVERY MUST BE RECEIVED BY THE EXCHANGE AGENT, PRIOR TO THE
