         On February 7, 2000 (the "Confirmation Date"), the United States
         Bankruptcy Court for the Southern District of Texas, Corpus Christi
         Division, signed and entered an order (the "Confirmation Order")
         confirming the Company's Second Amended, Modified and Restated
         Plan of Reorganization dated January 25, 2000 (the "Plan") under

         occur as soon as practicable. The following summary of the Plan is
         qualified by reference to the Plan, the Disclosure Statement and
         Confirmation Order. Copies of the Plan and Confirmation Order are
         attached hereto as Exhibits 2.1 and 2.2. Capitalized terms that are not
         defined herein shall have the meanings given them in the Plan.

         On the Effective Date, the Company's existing securities, including the
         $450 million TransTexas Senior Secured Note, $115.8 million of
         TransTexas Subordinated Notes, and all of the Company's issued and

otherwise provided in the Plan, any Plan Document or the Confirmation Order: (a)
each holder of (i) a Miscellaneous Secured Claim, (ii) a Bondholder DIP Secured
Claim, (iii) a Secured Claim other than the GMAC Secured Claim, (iv) a judgment,
and (v) a Mineral Interest Claim, shall on the Effective Date (x) turn over and
release to the Reorganized Debtor any and all Collateral that secures or
purportedly secures such Claim, as they pertain to the properties currently
owned or leased by the Debtor or such Lien shall automatically, and without
further action by the Debtor or Reorganized Debtor, be deemed released, and (y)
execute such documents and instruments as the Reorganized Debtor requests to
evidence such Claim holder's release of such property or Lien; and (b) on the
Effective Date, all right, title and interest in any and all property of the
Estate shall revert or be transferred to the Reorganized Debtor free and clear
of all Claims and Interests, including, without limitation, Liens, escrows,
charges, pledges, encumbrances and/or security interests of any kind (other than
the Liens in favor of GMAC provided for herein). No Distribution hereunder shall
be made to or on behalf of any Claim holder unless and until such holder
executes and delivers to the Debtor or Reorganized Debtor such release of Liens
or otherwise turns over and releases such Cash, pledge, or other possessory
Lien. Any such holder that fails to execute and deliver such release of Liens
within 120 days of the Effective Date shall be deemed to have no further Claim
against the Debtor, the Reorganized Debtor or its assets or property in respect
of such Claim and shall not participate in any Distribution hereunder.
Notwithstanding the immediately preceding sentence, any holder of a Disputed
Claim shall not be required to execute and deliver such release until such time
as the Claim is Allowed or Disallowed.

         Section 6.14 Election of Treatment in Class 8. Each holder of a Claim
in Class 8 may elect, in the Ballot/Election by which it votes to reduce the
amount of its Claim to $500 or less and thereby be deemed a holder of a Claim in
Class 10 for purposes of voting and payment under the Plan. Holders of Claims in
any other class shall not be entitled to make an election into Class

10 pursuant to this Plan. Any such election shall be effective only upon the
receipt thereof by the Debtor prior to the Confirmation Date. Once the election
is made, and received by the Debtor, such election shall be irrevocable and
binding on any successor-in-interest with respect to such Claim, but shall not
preclude the Debtor and/or other Entities from objecting to such Claim as
reduced.

         Section 6.15 Liens Securing New Senior Secured Notes; Further
Transactions. On the Effective Date, the Reorganized Debtor shall execute and
deliver to Firstar, in connection with the New Senior Secured Notes Indenture,
such documents, instruments and agreements as are necessary to confer the
priority of TEC with respect to its Liens under the TransTexas Senior Secured
Loan Agreement and the documents, instruments and agreements entered into in
connection therewith and to confer the priority of Firstar with respect to its
Liens under the TEC Senior Secured Notes Indenture and the documents,
instruments and agreements entered into in connection therewith. On the
Effective Date, the Reorganized Debtor shall execute and deliver such further
documents, instruments and agreements as are necessary to effectuate and further
evidence the terms and conditions of the Plan.

         Section 6.16 Payment of Fees.

         (a) All fees payable on or before the Effective Date (i) pursuant to
section 1930 of title 28 of the United States Code, as determined by the Court
at the Confirmation Hearing, and (ii) to the United States Trustee, shall be
paid by the Debtor on or before the Effective Date and all such fees payable
after the Effective Date shall be paid by the Reorganized Debtor.

         (b) All reasonable fees and expenses (including reasonable attorneys'
fees) incurred by Bank One, as Indenture Trustee, on or before the Effective
Date, in an estimated amount of $175,000, shall be paid by the Reorganized
Debtor on the Effective Date, or as soon thereafter as is practicable, without
prior approval of the Bankruptcy Court. The payment of such fees and costs shall
not reduce the Distributions to the holders of Allowed TransTexas Subordinated
Note Claims.

                                   ARTICLE VII

                  DISPUTED CLAIMS, DISPUTED INTERESTS, RESERVES
                    AND MISCELLANEOUS DISTRIBUTION PROVISIONS

         Section 7.01 Objections. An objection to the allowance of a Claim
(other than an Administrative Expense Claim) or Interest shall be in writing and
may be Filed by the Debtor or Reorganized Debtor, or any other party in
interest, at any time on or before the Objection Deadline. The "Objection
Deadline" is the later of (a) the 120th day following the Effective Date unless
such period is extended by order of the Bankruptcy Court, (b) sixty (60) days
after the Filing of the proof of such Claim or Interest or (c) such other date
set by order of the Bankruptcy Court (the application for which may be made on
an ex parte basis). The objecting party shall serve a copy of each such
Objection upon the holder of the Claim or Interest to which it pertains and upon
the Debtor or the Reorganized Debtor, as the case may be, and, prior to the
Effective Date, the Debtor or the Reorganized Debtor will prosecute each
Objection to a Claim or Interest until determined by a Final Order unless the
Debtor or the Reorganized Debtor (i) compromises and settles an Objection to a

<PAGE>   41


Claim or Interest by written stipulation, subject to Bankruptcy Court approval,
if necessary or (ii) withdraws an Objection to a Claim or Interest.

         Section 7.02 Amendments to Claims; Claims Filed After the Confirmation
Date. Except as otherwise provided in this Plan, after the Confirmation Date, a
Claim may not be Filed or amended without the authorization of the Bankruptcy
Court and, even with such Bankruptcy Court authorization, may be amended by the
holder of such Claim solely to decrease, but not to increase, the Face Amount
thereof. Except as otherwise provided in this Plan, any new or amended Claim
Filed after the Confirmation Date shall be deemed Disallowed in full and
expunged without any action by the Debtor or Reorganized Debtor.

         Section 7.03 Reserves for Disputed Claims and Disputed Interests.

         (a) On the Effective Date, Reorganized Debtor shall reserve sufficient
shares of New Common Stock to be issued to the holders of Class 4 Claims and
other distributees as specified in Section 5.03.

         (b) On the Effective Date, the Reorganized Debtor shall transmit to the
Disbursing Agent, and the Disbursing Agent shall reserve for the account of each
holder of a Disputed Claim or Interest, (i) the property which would otherwise
be distributable to such holder on such date in accordance with the Plan were
such Disputed Claim or Disputed Interest an Allowed Claim or Allowed Interest,
as applicable, on such date, in the Face Amount thereof, or such other amount as
ordered or estimated by the Bankruptcy Court or (ii) such other property as such
holder and the Reorganized Debtor may agree; provided, however, in no event
shall the Cash reserve exceed the Maximum GUC Cash Amount as it relates to the
holders of Class 8 Claims. Property reserved under this Section 7.03(b) shall be
set aside and to the extent practicable, held by the Disbursing Agent in an
interest bearing account to be established and maintained by the Disbursing
Agent pending resolution of such Disputed Claim, provided, however, that Cash
shall be invested in a manner consistent with the requirements of Section 345 of
the Bankruptcy Code or otherwise ordered by the Bankruptcy Court. To the extent
such Disputed Claim or Disputed Interest becomes an Allowed Claim or Allowed
Interest, the property so reserved for the holder thereof, together with any
proceeds thereon, shall be distributed by the Disbursing Agent to such holder
pursuant to, and to the extent provided for in the Plan. To the extent an
objection to a Class 8 Claim is upheld or a Class 8 Claim is withdrawn or
reduced, the reserves held on account of such Disputed or withdrawn Claim shall
be reallocated and paid to the holders of Allowed Class 8 Claims at the time of
the next Quarterly Distribution Date.

         (c) Any voting rights of Reorganization Securities held in reserve in
respect of a Disputed Claim or Disputed Interest shall be suspended until such
securities are released from such reserve.

         Section 7.04 Fluctuation in Value of Securities. The value of the
Reorganization Securities held in reserve under Section 7.03 of the Plan is
likely to fluctuate. The Reorganized Debtor does not represent or warrant that
the value of any Reorganization Securities will not decline after the Effective
Date and they do not otherwise assume any liability or risk of loss which the
holder of a Disputed Claim or Disputed Interest which becomes an Allowed Claim
or Allowed

<PAGE>   42


Interest, as applicable, after the Effective Date may suffer by reason of any
decline in value of a reserved Reorganization Securities pending determination
of the amount of such Disputed Claim. The risk or benefit of any appreciation or
depreciation in the value of any reserved Reorganization Securities shall be
borne solely by the Entity to whom such Reorganization Securities is ultimately
distributed.

         Section 7.05 Distributions on Account of Disputed Claims. In
determining the amount of Distributions to be made under the Plan to the holders
of Allowed Claims on the Effective Date or a Quarterly Distribution Date, the
appropriate Distributions shall be made as if all the Disputed Claims as of such
Distribution Date were Allowed Claims in the full amount claimed by the holders
thereof, unless otherwise ordered or estimated by the Court. No Distributions
will be made on a Disputed Claim or Disputed Interest unless and until such
Disputed Claim or Disputed Interest becomes an Allowed Claim or Allowed
Interest.

         Section 7.06 Quarterly Distributions. On the Quarterly Distribution
Date, the Disbursing Agent shall make Ratable Proportion or other Distributions
of Cash or Reorganization Securities reserved for any Disputed Claim that has
become an Allowed Claim during the preceding quarterly period. Additionally, on
each Quarterly Distribution Date, the Reorganized Debtor, shall distribute to
holders of previously Allowed Class 8 Claims their Ratable Proportion of
distributable cash in the Cash Reserve Account less the total amount of any
Distribution previously received.

         Section 7.07 Excess Reserves. On the date on which all Class 8 Claims
and Class 10 Claims are either Allowed or Disallowed Claims and all payments
required to be made pursuant to the Plan to the holders of such Allowed Claims
shall have been made, all Cash and Reorganization Securities reserved for the
payment of, or Distribution on, the Disallowed portion of Disputed Claims and
Disputed Interests and not required to be otherwise Distributed pursuant to the
Plan, shall immediately and irrevocably vest in the Reorganized Debtor and the
Disbursing Agent shall transmit such property to the Reorganized Debtor,
whereupon the Reorganized Debtor shall thereafter be empowered to take whatever
steps may be necessary to exercise control over such property. Notwithstanding
the foregoing, the disallowed portion of any Disputed Claim in Class 8 shall
always be reallocated to the holders of Allowed Class 8 Claims with no portion
or amount returning or vesting in the Reorganized Debtor. Shares of New Common
Stock that are reserved pursuant to Section 7.03 for issuance but not issued
shall remain authorized but unissued New Common Stock.

         Section 7.08 Undeliverable or Unclaimed Distributions. Any Entity that
is entitled to receive a Cash Distribution under this Plan but that fails to
cash a check within 120 days of its issuance shall be entitled to receive a
reissued check from the Reorganized Debtor for the amount of the original check,
without any interest, if such Entity requests the Reorganized Debtor or its
designee to reissue such check and provides the Reorganized Debtor or its
designee, with such documentation as the Reorganized Debtor or its designee
requests to verify that such Entity is entitled to such check, prior to the
later of (a) the second anniversary of the Effective Date or (b) six (6) months
after such Claim becomes an Allowed Claim. If an Entity fails to cash a check
within 120 days of its issuance and fails to request reissuance of such check
prior to the later to occur of (a) the second anniversary of the Effective Date
or (b) six (6) months following the date such Entity's Claim becomes an Allowed
Claim, such Entity shall not be entitled to receive any

<PAGE>   43


Distribution under this Plan with respect to the amount of such check. If the
Distribution to any holder of an Allowed Claim or Interest is returned to the
Reorganized Debtor or its designee as undeliverable, no further Distributions
will be made to such holder unless and until the Reorganized Debtor or its
designee is notified in writing of such holder's then-current address.

         All Claims for undeliverable Distributions must be made on or before
the later to occur of (i) the second anniversary of the Effective Date and (ii)
six (6) months following the date such Entity's Claim becomes an Allowed Claim
or Allowed Interest. After such date, all unclaimed property shall revert to the
Firstar (except amounts payable to Class 8) for further Distribution to the TEC
Bondholders pursuant to the terms of the TEC Senior Secured Notes Indenture and
this Plan, and the Claim of any holder or successor to such holder with respect
to such property shall be discharged and forever barred notwithstanding any
federal or state escheatment laws to the contrary.

         Section 7.09 Allocation of Consideration. The aggregate consideration
to be distributed to the holders of Allowed Claims in each Class under this Plan
shall be treated as first satisfying an amount equal to the stated principal
amount of the Allowed Claim for such holders and any remaining consideration as
satisfying accrued, but unpaid, interest through the Effective Date, if any.

         Section 7.10 Distributions to the Holders of General Unsecured Claims.
For purposes of formulating this Plan, the Debtor has estimated the aggregate
total of Allowed General Unsecured Claims, after the resolution of all disputes,
to be approximately $100 million. In connection with the process of resolution
of Disputed Claims, the Bankruptcy Court will determine the amount of ultimately
Allowed General Unsecured Claims and consequently, the final Distributions to
holders of Allowed General Unsecured Claims pursuant to this Plan.

         Section 7.11 Transmittal of Distributions and Notices.

         (a) Any property or notice other than Cash Distributions made through
Section 7.14 which an Entity is or becomes entitled to receive pursuant to the
Plan shall be delivered by regular mail, postage prepaid, in an envelope
addressed to that Entity at the address indicated on any notice of appearance
Filed by that Entity or his authorized agent prior to the Effective Date. If no
notice of appearance has been Filed, notice shall be sent to the address
indicated on a properly Filed proof of Claim or Interest or, absent such a proof
of Claim or Interest, the address that is Scheduled for that Entity or register
maintained for register securities. The date of Distribution shall be the date
of mailing, and property distributed in accordance with this Section shall be
deemed delivered to such Entity regardless of whether such property is actually
received by that Entity.

         (b) A holder of a Claim or Interest may designate a different address
for notices and Distributions by notifying the Debtor or the Reorganized Debtor,
or with respect to the holder of a TransTexas Senior Secured Note Claims,
Firstar, or with respect to a holder of a TransTexas Subordinated Note Claim,
Bank One, of that address in writing. The new address shall be effective upon
receipt by the Debtor or the Reorganized Debtor, as the case may be.

<PAGE>   44


         (c) Notwithstanding anything to the contrary herein and above, to the
extent that a Distribution is required to be made to a Paying Agent, the address
for the relevant Claim or Interest shall be the address of the relevant Paying
Agent.

         Section 7.12 Distribution Record Date. As of the close of business on
the Distribution Record Date, the transfer register for the TransTexas
Subordinated Notes will be closed, and the Disbursing Agent, Bank One, and their
respective agents will have no obligation to recognize the transfer of any
TransTexas Subordinated Notes occurring after such time and will be entitled for
all purposes herein to recognize and deal only with those holders of record as
of such time.

         Section 7.13 Method of Cash Distributions. Any Cash payment to be made
pursuant to this Plan may be made by draft, check, wire transfer, or as
otherwise required or provided in any relevant agreement or applicable law.

         Section 7.14 Distributions on Non-Business Days. Any Distribution due
on a day other than a Business Day shall be made, without interest, on the next
Business Day.

         Section 7.15 Rounding. Notwithstanding any other provision of the Plan,
only whole numbers of shares of New Senior Preferred Stock, New Junior Preferred
Stock and New Common Stock and whole numbers of New Warrants will be issued and
distributed. When any Distribution on account of an Allowed Claim would
otherwise result in the issuance of a number of shares of New Senior Preferred
Stock, New Junior Preferred Stock and New Common Stock or a number of New
Warrants that is not a whole number, the actual Distribution of shares of such
stock or warrants will be rounded to the next higher or lower whole number as
follows: (i) fractions equal to or greater than 1/2 will be rounded to the next
higher whole number and (ii) fractions less than 1/2 will be rounded to the next
lower number. The total number of shares of New Senior Preferred Stock, New
Junior Preferred Stock and New Common Stock and New Warrants to be distributed
to a Class of Claims or Interests will be adjusted as necessary to account for
the rounding provided for herein. If, as a result of such rounding, the amount
of shares of New Senior Preferred Stock, New Junior Preferred Stock and New
Common Stock or the amount of New Warrants to be distributed to a particular
Class differs from the aggregate number of shares of New Senior Preferred Stock,
New Junior Preferred Stock and New Common Stock or New Warrants to be
distributed pursuant to the Plan to that Class, the aggregate number of shares
of New Senior Preferred Stock, New Junior Preferred Stock and New Common Stock
or the amount of New Warrants specified with respect to such Class will be
adjusted upward or downward to provide for the Distribution of New Senior
Preferred Stock, New Junior Preferred Stock and New Common Stock or New
Warrants, as the case may be, in an aggregate number of shares or New Warrants
equal to such sum. No consideration will be provided in lieu of fractional
shares or warrants that are rounded down.

         Section 7.16 Withholding Taxes. Any federal, state or local withholding
taxes or other amounts required to be withheld under applicable law shall be
deducted from Distributions hereunder. All Entities holding Claims shall be
required to provide any information necessary to effect the withholding of such
taxes.

<PAGE>   45


         Section 7.17 Disputed Distributions. If any dispute arises as to the
identity of a holder of an Allowed Claim or an Allowed Interest who is to
receive any Distribution, the Disbursing Agent, Firstar, or Bank One may, in
lieu of making such Distribution to such Entity, make such Distribution into an
escrow account until the disposition thereof shall be determined by Final Order
of the Bankruptcy Court or by written agreement among the interested parties to
such dispute.

         Section 7.18 Retention of Rights to Pursue Causes of Action. Pursuant
to Section 1123(b)(3) of the Bankruptcy Code, the Reorganized Debtor (as
representatives of the Debtor's estate) will retain and have the exclusive right
to enforce against any Entity any and all Causes of Action (including, without
limitation, all Causes of Action arising under Sections 510, 544 through 550 and
553 of the Bankruptcy Code or otherwise arising under the Bankruptcy Code and/or
those arising under other applicable law) that arose before the Effective Date,
including all Causes of Action of a trustee and debtor-in-possession under the
Bankruptcy Code, other than those expressly released or compromised as part of
or pursuant to this Plan (including those specified under the GMAC Waiver and
Injunction); provided, however, that all Causes of Action that arose before the
Effective Date relating to any of the Distributions received by the holder of
the TransTexas Senior Secured Note Claims pursuant to Section 5.03(a) and not
reallocated pursuant to Section 5.03(b) are hereby assigned to Firstar on behalf
of the TEC Bondholders.

         Section 7.19 Reviewer Proceedings. All Disputed Secured Claims of a M&M
Lien Claimant, other than the Excluded M&M Lien Claimants, shall be referred to
the Reviewer. The Reviewer shall make findings of fact and shall refer all
questions of law to the Bankruptcy Court. The Reviewer shall enter findings and
conclusions as to the allowance of a Disputed Secured Claim of a M&M Lien
Claimant; provided, however, that any party may obtain a trial de novo before
the Bankruptcy Court by appealing the Reviewer's finding and conclusions within
10 days of the Reviewer's Filing of his report to the Bankruptcy Court.

         Section 7.20 Instructions Regarding Sale of New Senior Preferred Stock.
Subsequent to the Effective Date or as soon thereafter as practicable, the
Debtor will deliver to the Disbursing Agent five million shares of New Senior
Preferred Stock. The Executive Committee will instruct the Disbursing Agent when
to sell the shares of the New Senior Preferred Stock. The Executive Committee
intends to sell the stock as soon as commercially practicable.

         Section 7.21 Payment of Allowed Class 8 Claims. On the Effective Date,
the Debtor will transmit to the Disbursing Agent the Maximum GUC Cash Amount and
five million shares of the New Senior Preferred Stock. The Disbursing Agent will
keep the proceeds received on account of Class 8 Claims in a segregated account
strictly and solely for the benefit of Class 8 Claimants and neither the Debtor
nor Reorganized TransTexas shall retain any interest in such segregated account.
The Disbursing Agent shall account to the Executive Committee with respect to
any Distribution made from these segregated funds.

                                  ARTICLE VIII

              TREATMENT OF EXECUTORY CONTRACTS AND UNEXPIRED LEASES

         Section 8.01 Assumption Generally. Except as otherwise provided in this
Plan or in any order of the Bankruptcy Court, subject to the occurrence of the
Effective Date, on the Effective Date, pursuant to Section 365 of the Bankruptcy
Code, all executory contracts and unexpired leases not listed on the Schedule of
Rejected Contracts to be served and Filed by the Debtor at least five (5) days
before the Confirmation Hearing (the "Schedule of Rejected Contracts"), or which
is not the subject of a motion to reject as of the Confirmation Date, and is not
rejected under Section 8.06 hereof, are assumed, subject to the same rights that
the Debtor or the Reorganized Debtor held or holds at, on, or after the Petition
Date to modify or terminate such agreements under applicable nonbankruptcy law.
Each contract and lease assumed under this Section shall be assumed only to the
extent, if any, that it constitutes an executory contract or unexpired lease,
and nothing contained herein shall constitute an admission by the Debtor or the
Reorganized Debtor that such contract or lease is an executory contract or
unexpired lease or that the Debtor or the Reorganized Debtor has any liability
thereunder. To the extent the Bankruptcy Court, or any other court of competent
jurisdiction, determines, either before, on, or after the Effective Date, that
any agreement in the form of a lease of real or personal property identified for
assumption in this Article VIII of the Plan, is, in fact, a secured transaction,
the resulting secured indebtedness arising from such determination shall be
treated in accordance with the applicable section of the Plan. Each executory
contract and unexpired lease assumed pursuant to this Article VIII shall revest
in and be fully enforceable by the Reorganized Debtor in accordance with its
terms, except as modified by the provisions of the Plan, any order of the
Bankruptcy Court authorizing and providing for its assumption, or applicable
federal law.

         Section 8.02 Approval of Assumptions. Subject to the occurrence of the
Effective Date, the Confirmation Order (except as otherwise provided therein)
shall constitute an order of the Bankruptcy Court approving the assumptions,
revestments and, to the extent not subject to dispute as set forth in Section
8.04, of the "cure" amounts described in this Article VIII and the Cure Amount
Schedule attached to the Schedule of Rejected Contracts pursuant to Section 365
of the Bankruptcy Code effective as of the Effective Date.

         Section 8.03 Objections to Assumption of Executory Contracts and
Unexpired Leases.

         (a) Any Entity objecting to the Debtor's proposed assumption of an
executory contract or unexpired lease based on a lack of adequate assurance of
future performance or on any ground other than the adequacy of the "cure" amount
set forth in the Cure Amount Schedule, shall have Filed and served a written
objection to the assumption of such contract or lease on or before 4:30 p.m.
Central Standard Time on November 4, 1999. Failure to File an objection within
the time period set forth above shall constitute consent to the assumption and
revestment of those contracts and leases, including an acknowledgment that the
proposed assumption provides adequate assurance of future performance.

         (b) If any Entity Files an objection to assumption based on any ground
other than the adequacy of the "cure" amount set forth in the Cure Amount
Schedule, and the Bankruptcy Court ultimately determines that the Debtor cannot
assume the executory contract or lease or that the Debtor cannot provide
adequate assurance of future performance as proposed or in any modified

proposal submitted by the Debtor or the Reorganized Debtor, then the unexpired
lease or executory contract shall automatically thereupon be deemed to have been
included on the Schedule of Rejected Contracts and shall be rejected pursuant to
Section 8.06 hereof.

         Section 8.04 Objections to Proposed "Cure" Amounts.

         (a) The Debtor believes that any executory contract of the Debtor that
is not listed on the Schedule of Rejected Contracts or in the Cure Amount
Schedule may be assumed by the Debtor without the payment of any monetary cure
amount. Any party to an executory contract or unexpired lease to be assumed that
asserts arrearages or damages pursuant to Section 365(b)(1) of the Bankruptcy
Code that exceeds the amount set forth in the Cure Amount Schedule, or which is
not listed therein and pertains to an executory contract not listed in the
Schedule of Rejected Contracts must have Filed and served an objection to the
proposed cure amount on or before 4:30 p.m. Central Standard Time on November 4,
1999. Failure to assert arrearages different from the amount set forth on the
Cure Amount Schedule or which pertains to an executory contract not listed in
the Schedule of Rejected Contracts or the Cure Amount Schedule within the time
period set forth above shall constitute consent to the cure amount set forth in
the Cure Amount Schedule or to the Debtor's position that no cure amount must be
paid and an acknowledgment that the amount identified for "cure" on the Cure
Amount Schedule is the only amount necessary to cover any and all outstanding
defaults under the respective executory contract or unexpired lease to be
assumed and an acknowledgment that no other defaults exist under said contract
or lease.

         (b) To the extent that any objections to the amounts set forth in the
Cure Amount Schedule are timely Filed and served and such objections are not
resolved between the Debtor and the objecting Entities, the Bankruptcy Court
shall resolve such disputes at a hearing to be held at a date to be determined
by the Bankruptcy Court at the Confirmation Hearing. The resolution of such
disputes shall not affect the Debtor's assumption of the contracts or leases
that are subject of such a dispute, but rather shall affect only the "cure"
amount the Debtor must pay in order to assume such contract or lease.
Notwithstanding the immediately preceding sentence, if the Debtor in its
discretion determines that the amount asserted to be the necessary "cure" amount
would, if ordered by the Bankruptcy Court, make the assumption of the contract
or lease imprudent, then the Debtor may, prior to or at the Confirmation
Hearing, elect to (1) reject the contract or lease pursuant to Section 8.06
hereof, or (2) request an expedited hearing on the resolution of the "cure"
dispute, exclude assumption or rejection of the contract or lease from the scope
of the Confirmation Order, and retain the right to reject the contract or lease
pursuant to Section 8.06 hereof pending the outcome of such dispute.

         Section 8.05 Payment Related to Assumption of Executory Contracts and
Unexpired Leases. If not the subject of dispute pursuant to Section 8.04 hereof
as of Confirmation Date, any monetary defaults under each executory contract and
unexpired lease to be assumed under the Plan shall be satisfied by the Debtor,
pursuant to Section 365(b)(1) of the Bankruptcy Code, by payment of the amount
set forth in the Cure Amount Schedule or such other amount as ordered by the
Bankruptcy Court or agreed upon by the Debtor in Cash within 60 days following
the Effective Date or on such other terms as agreed to by the parties to such
executory contract or unexpired lease. In the event of a dispute pursuant to
Section 8.04, payment of the amount otherwise payable

hereunder shall be made following entry of a Final Order or agreement by the
Debtor or the Reorganized Debtor, as the case may be, and the party to the
contract or lease.

         Section 8.06 Executory Contracts and Unexpired Leases to be Rejected.

         (a) Effective as of, and subject to the occurrence of, the Effective
Date, the executory contracts and unexpired leases listed on the Schedule of
Rejected Contracts shall be rejected as of the Effective Date. The Debtor may
amend the Schedule of Rejected Contracts at any time prior to the Confirmation
Hearing (i) by Filing such amendment with the Bankruptcy Court and serving it on
parties directly affected by the amendment; or (ii) with Bankruptcy Court
approval after a hearing on notice to the Creditors' Committee and the affected
parties. Listing a contract or lease by category above or on the Schedule of
Rejected Contracts shall not constitute an admission by the Debtor or the
Reorganized Debtor that such contract or lease, including related agreements, is
an executory contract or unexpired lease or that the Debtor or the Reorganized
Debtor have any liability thereunder.

         (b) The Confirmation Order shall constitute an order of the Bankruptcy
Court approving such rejections on the Confirmation Date, pursuant to Section
365 of the Bankruptcy Code, effective as of the Effective Date. Any party to an
executory contract or unexpired lease identified for rejection as provided
herein may, within the same deadline and in the same manner established for
Filing objections to Confirmation, file any objection thereto. Failure to file
any such objection within the time period set forth above shall constitute
consent and agreement to the rejection.

         Section 8.07 Bar Date for Rejection Damages. If the rejection of an
executory contract or unexpired lease pursuant to Section 8.06 above gives rise
to a Claim by the other party or parties to such contract or lease, such Claim,
to the extent that it is timely Filed and is a Miscellaneous Secured Claim,
shall be classified in Class 6, and to the extent that it is timely Filed and is
a General Unsecured Claim, shall be classified in Class 8 or Class 10, as the
case may be; provided, however, that in either event any Claim arising from the
rejection shall be forever barred and shall not be enforceable against the
Debtor, the Reorganized Debtor, their affiliates, their successors, estates, or
their properties, unless a proof of Claim is Filed and served on the Debtor or
the Reorganized Debtor within thirty days after the earlier of (a) the date of
entry of the first order of the Bankruptcy Court rejecting the executory
contract or unexpired lease, or (b) the Confirmation Date.

         Section 8.08 Contracts Entered Into on or After the Petition Date. On
the Effective Date, all contracts, leases, and other agreements entered into by
the Debtor on or after the Petition Date, which agreements have not been
terminated in accordance with their terms on or before the Confirmation Date
shall revest in and remain in full force and effect as against the Reorganized
Debtor and the other parties to such contracts, leases and other agreements.

with respect to the Claim, before any Distribution is made on account of such
Claim, any and all of the Claims, rights and causes of action of any nature that
the Debtor or the Reorganized Debtor may hold against the holder of such Claim;
provided, however, that neither the failure to effect such a setoff, the
allowance of any Claim hereunder, any other action or omission of the Debtor or
the Reorganized Debtor, nor any provision of this Plan shall constitute a waiver
or release by the Debtor or the Reorganized Debtor of any such Claims, rights
and causes of action that the Debtor or the Reorganized Debtor may possess
against such holder. To the extent the Reorganized Debtor fails to set off
against a holder of a Claim or Interest and seek to collect a Claim from the
holder of such Claim or Interest after a Distribution to the holder of such
Claim or Interest pursuant to the Plan, the Reorganized Debtor shall be entitled
to full recovery on its Claim against the holder of such Claim or Interest.

proper pursuant to 28 U.S.C. Sections 1408 and 1409.

         B. Solicitation. In accordance with the Disclosure Statement Order and
as evidenced by the Ballot Certification, the Debtor caused (1) the Solicitation
Materials to have been distributed to all known holders of Claims (including the
beneficial holders of the TEC Senior Secured Notes with respect to Class 3)
and/or Interests entitled to vote on the Second Amended Plan, (2) the Second
Amended Plan to have been distributed to each holder of a Claim and/or an
Interest not entitled to vote on the Second Amended Plan and (3) notice of the
Confirmation Hearing and the deadline for voting on Filing objections to the
Second Amended Plan to have been duly given. Such actions constitute due,
sufficient and adequate notice to all known holders of Claims and Interests of
the Plan, the Confirmation Hearing and the deadlines for submitting votes on,
and Filing objections to the confirmation of, the Plan.

         C. Procedures for Voting. As evidenced by the Ballot Certification,
the procedures by which ballots for voting on the Plan were received and
tabulated were fair, properly conducted and

in accordance with the Bankruptcy Code, the Bankruptcy Rules, the local rules
of this Court and the Disclosure Statement Order.

         D. Satisfaction of Confirmation Requirements. Section 1129(a)(1) of
the Bankruptcy Code is satisfied because the Plan complies with all the
applicable provisions of the Bankruptcy Code, including the provisions of
Sections 1122 and 1123 of the Bankruptcy Code:


            (1) Proper Classification of Claims and Interests. Section 1122(a)
and 1123(a)(1) of the Bankruptcy Code are satisfied because the Plan properly
designates separate Classes of Claims and Interests, each of which contains
only Claims or Interests that are substantially similar to the other Claims or
Interests within that Class.



            (2) Specification of Unimpaired Classes. Section 1123(a)(2) of the
Bankruptcy Code is satisfied because the Plan properly designates Classes of
Claims and Interests as impaired or unimpaired.


            (3) Specification of Treatment of Impaired Classes. Section 1123
(a)(3) of the Bankruptcy Code is satisfied because the Plan specifies the
treatment of each Class of Claims and Interests that is impaired under the
Plan, to the extent that the Claims or Interests within such Class are Allowed
Claims or Allowed Interests, respectively.


            (4) Equal Treatment Within Classes. Section 1123(a)(4) of the
Bankruptcy Code is satisfied because the Plan provides the same treatment for
each Allowed Claim or Allowed Interest within a particular Class or the holder
of a particular Allowed Claim or Allowed Interest has agreed to a less
favorable treatment of such Claim or Interest.

MODIFIED AND RESTATED PLAN OF REORGANIZATION                           Page 6




<PAGE>   7

            (5) Implementation of Plan. Section 1123(a)(5) of the Bankruptcy
Code is satisfied because the Plan provides adequate means for its
implementation.

            (6) Charter Provisions. Section 1123(a)(6) of the Bankruptcy Code is
satisfied because the Amended Certificate of Incorporation of Reorganized
TransTexas prohibits the issuance of nonvoting equity securities to the extent
prohibited by that Section.

            (7) Selection of Officers and Directors. Section 1123(a)(7) of the
Bankruptcy Code is satisfied because the Plan contains only provisions that are
consistent with the interests of holders of Claims and Interests and with
public policy with respect to the manner of selection of the Reorganized
TransTexas' officers and directors, and any successor to such officers and
directors.

            (8) Bankruptcy Rule 3016(a). Rule 3016(a) of the Bankruptcy Rules is
satisfied because the Plan is dated and identifies the entity submitting it.


         E. Debtor's Compliance with the Applicable Provisions of the
Bankruptcy Code. Section 1129(a)(2) of the Bankruptcy Code is satisfied because
the Debtor has complied with all applicable provisions of the Bankruptcy Code.


         F. Plan Proposed in Good Faith. Section 1129(a)(3) of the Bankruptcy
Code is satisfied because the Plan was proposed in good faith and not by any
means forbidden by law. In determining that the Plan has been proposed in good
faith, the Court has examined the totality of circumstances surrounding the
filing of the Chapter 11 Case and the formulation of the Plan. The Chapter 11
Case was filed, the Plan was proposed with the legitimate and honest purposes
of reorganizing the Debtor and expeditiously distributing Cash and securities
in Reorganized TransTexas to the Debtor's creditors and equity security
holders. Further, the Plan is the product of months of extensive, arms'

MODIFIED AND RESTATED PLAN OF REORGANIZATION                              Page 7

length negotiations among the Debtor, the Bondholder Committee, the Creditors'
Committee, the SubDebt Committee, GMAC and the Post Confirmation Credit
Facility Lenders and their respective counsel and financial advisors.


         G. Payment for Services and Expenses. Section 1129(a)(4) of the
Bankruptcy Code is satisfied because, to the extent required by that Section,
any payment made or to be made by the Debtor for services or for costs and
expenses in, or in connection with, the Chapter 11 Case, or in connection with
the Plan and incident to the Chapter 11 Case, has been approved by, or is
subject to the approval of, the Bankruptcy Court as reasonable.


         H. Directors, Officers and Insiders. Section 1129(a)(5) of the
Bankruptcy Code is satisfied because the Debtor has disclosed the identities
and affiliations of all Persons proposed to serve as a director or officer of
Reorganized TransTexas; and the appointment of such Persons to, or the
continuance of such Persons in, such offices is consistent with the interests
of the holders of Claims and Interests and with public policy; and the Debtor
has disclosed the identity of any insider who will be employed or retained by
Reorganized TransTexas, and the nature of any compensation for such insider. As
provided at page 111 of the Disclosure Statement, the executive officers of
TransTexas immediately before confirmation of the Plan shall continue to serve
in their respective capacities at Reorganized TransTexas immediately after
confirmation of the Plan. That is, John R. Stanley shall serve as chief
executive officer, Ronald P. Nowak shall serve as president and chief operating
officer, Edwin B. Donahue shall serve as vice president, chief financial
officer and secretary, Simon Ward shall serve as vice president and treasurer,
and George Wright shall serve as vice president of accounting. As provided at
page 111 of the Disclosure Statement, on the

MODIFIED AND RESTATED PLAN OF REORGANIZATION                              Page 8

<PAGE>   9




Effective Date, each of the existing members of the board of directors or the
Debtor, other than Mr. John R. Stanley, will be deemed to have resigned. John
R. Stanley shall serve on the board of directors of Reorganized TransTexas. The
names and affiliations of each of the remaining four directors John Whitmire,
Walter Piontek, Gerald Bennett and Ronald Benson were disclosed at or before
the Confirmation Hearing.

         I. No Rate Changes. Section 1129(a)(6) of the Bankruptcy Code is
inapplicable because there is no governmental regulatory commission with
jurisdiction, after confirmation of the Plan, over rates of the Debtor.

         J. Best Interests of Creditors Test. Section 1129(a)(7) of the
Bankruptcy Code is satisfied. The liquidation analysis contained in Appendix 6
of the Disclosure Statement and other evidence proffered or adduced at the
Confirmation Hearing, including the testimony of Loretta Cross of
Pricewaterhouse Coopers, L.L.P., the Debtor's financial advisors, and David
Heather of The Scotia Group, Inc., the Debtor's valuation expert, are (i)
persuasive and credible, (ii) have not been controverted by other evidence, and
(iii) established that each holder of an impaired Claim or Interest either (x)
has accepted the Plan or (y) will receive or retain under the Plan, on account
of such Claim or Interest, property of a value, as of the Effective Date, that
is not less than the amount that such holder would so receive or retain if the
Debtor was liquidated under Chapter 7 of the Bankruptcy Code.

         K. Acceptance by Certain Classes. Section 1129(a)(8)(A) of the
Bankruptcy Code is satisfied with respect to Classes 2, 3, 4, 5, 6A (124 of 166
separate 6A Classes), 6B (14 of the 26 separate 6B Classes), and 10, which are
Classes of Claims impaired by the Plan, because such




ORDER CONFIRMING DEBTOR'S SECOND AMENDED,
MODIFIED AND RESTATED PLAN OF REORGANIZATION                           Page 9


<PAGE>   10



Classes have accepted the Plan pursuant to Section 1126(c) of the Bankruptcy
Code. Section 1129(a)(8)(B) of the Bankruptcy Code is satisfied with respect to
Classes 1 and 11, because such Classes are not impaired by the Plan and are
therefore conclusively deemed to have accepted the Plan under Section 1126(f) of
the Bankruptcy Code.


         L. Best Interests of Non-Accepting Classes. Section 1129(a)(8) of the
Bankruptcy Code has not been satisfied with respect to Classes 7, 8, 9 and 12
because these Classes are deemed not to have accepted the Plan pursuant to
Section 1126(g) of the Bankruptcy Code. Under the Plan, no holder of a Claim or
Interest that is junior to the Claims in Class 3 will receive or retain any
property under the Plan on account of such junior Claim or Interest; however,
the holder of the Class 3 Claims, subject to the occurrence of the Effective
Date, shall reallocate and direct the Reorganized Debtor to distribute certain
of the Distributions such holder is entitled to receive to the holders of
Claims and/or Interests in Classes 8, 9 and 12. The Claims and/or Interests in
Classes 7, 8, 9 and 12 are junior to Class 3 Claims and the holders of such
Claims and/or Interests will receive or retain under the Plan, on account of
such Claim and/or Interest, property of a value, as of the Effective Date, that
is not less than the amount that such holder would so receive or retain if the
Debtor was liquidated under Chapter 7 of the Bankruptcy Code. The Plan
therefore satisfies the requirements of Section 1129(b) of the Bankruptcy Code
and thus may be confirmed without compliance with Section 1129(a)(8) of the
Bankruptcy Code with respect to Classes 7, 8, 9 and 12. That is, the Plan (i)
does not discriminate unfairly against these Classes and (ii) is fair and
equitable with respect to these Classes. Section 1129(a)(8) has not been
satisfied with respect to 42 of the 166 separate 6A Classes and 12 of the
separate 6B Classes because such claimants in such Classes, as determined





ORDER CONFIRMING DEBTOR'S SECOND AMENDED,
MODIFIED AND RESTATED PLAN OF REORGANIZATION                           Page 10



<PAGE>   11



by the Court at the Confirmation Hearing, are deemed not to have accepted the
Plan. The Plan satisfies the requirements of Section 1129(b) of the Bankruptcy
Code and thus may be confirmed without compliance with Section 1129(a)(8) of
the Bankruptcy Code with respect to 42 of the 166 separate 6A Classes and 12 of
the separate 6B Classes. That is, the Plan (a) does not discriminate unfairly
against such Claimants in such Classes and (b) is fair and equitable with
respect to these Classes.


         M. Treatment of Priority Administrative Expense Claims. Section
1129(a)(9)(A) of the Bankruptcy Code is satisfied because the Plan provides
that (i) there are no Claims of a kind specified in Section 507(a)(2) of the
Bankruptcy Code and (ii)(a) Allowed Administrative Expense Claims arising from
liabilities incurred in the ordinary course of the Debtor's businesses shall be
assumed and paid by Reorganized TransTexas pursuant to the terms and conditions
of the particular transactions giving rise to such Administrative Expense
Claims and (b) Allowed Administrative Expense Claims of Professionals shall be
paid by Reorganized TransTexas upon submission of (or as otherwise agreed to
among the parties) applications for compensation and reimbursement of expenses
and allowance of the amounts sought in such applications by the Bankruptcy
Court.


         N. Treatment of Other Priority Claims. Section 1129(a)(9)(B) of the
Bankruptcy Code is satisfied because the Plan provides that each holder of an
Allowed Administrative Expense shall be entitled to receive the Allowed amount
of such Claim in full in Cash on or as soon as practicable after the later of
(i) the Effective Date and (ii) the date that such Claim becomes an Allowed
Administrative Expense.

MODIFIED AND RESTATED PLAN OF REORGANIZATION                           Page 11


<PAGE>   12



         O. Treatment of Priority Tax Claims. Section 1129(a)(9)(C) of the
Bankruptcy Code is satisfied because the Plan provides that, unless otherwise
agreed by the holder of an Allowed Priority Tax Claim and Reorganized
TransTexas, each holder of an Allowed Priority Tax Claim shall receive, at
Reorganized TransTexas' option, either (a) equal Cash payments made on the last
Business Day of every three (3) month period following the Effective Date, over
a period not exceeding six (6) years after the assessment of the tax on which
such Claim is based, totaling the principal amount of such Claim plus simple
interest on any outstanding balance from the Effective Date calculated at an
interest rate of 10% per annum with respect to all Priority Tax Claims; (b)
such other treatment agreed to by the holder of such Allowed Priority Tax Claim
and Reorganized TransTexas, provided such treatment is on more favorable terms
to Reorganized TransTexas than the treatment set forth in clause (a); or (c)
the full amount in Cash of such Allowed Priority Tax Claim or as soon as
practicable after the later of (i) the Effective Date or (ii) the date on which
such Priority Tax Claim becomes an Allowed Priority Tax Claim.

         P. Acceptance of at Least One Impaired Class. Section 1129(a)(10) of
the Bankruptcy Code is satisfied because at least one Class of Claims that is
impaired under the Plan has accepted the Plan, determined without including any
acceptance by an insider. Impaired Classes 2, 3, 4, 5, 6A (124 of such separate
6A Classes), 6B (12 of such separate 6B Classes) and 10 have so accepted the
Plan.

         Q. Feasibility. Section 1129(a)(11) of the Bankruptcy Code is
satisfied because confirmation of the Plan is not likely to be followed by the
need for further financial reorganization or liquidation of the Debtor or
Reorganized TransTexas. As part of an analysis to determine whether




ORDER CONFIRMING DEBTOR'S SECOND AMENDED,
MODIFIED AND RESTATED PLAN OF REORGANIZATION                            Page 12

<PAGE>   13





the Debtor has the ability to meet its obligations under the Plan, the Debtor,
with the assistance of Pricewaterhouse Coopers, L.L.P., prepared projections of
its financial performance for the six fiscal years through January 31, 2006.
These projections and the assumptions upon which they are based, are included
in the Financial Projections attached to the Disclosure Statement as Appendix
2. Based on such projections, the Debtor believes that Reorganized TransTexas
will be able to make all payments required to be made pursuant to the Plan.


         R. Payment of Certain Fees. Section 1129(a)(12) of the Bankruptcy Code
is satisfied because pursuant to Section 6.16 of the Plan, all fees payable
under 28 U.S.C.ss. 1930 shall be paid on or before the Effective Date.


         S. Continuation of Retirement Benefits. Section 1129(a)(13) of the
Bankruptcy Code is satisfied because Section 6.08 of the Plan provides that
Reorganized TransTexas shall, to the extent and for the duration required by
such Section, continue to pay all retiree benefits (if any), as that term is
defined in Section 1114 of the Bankruptcy Code, maintained or established by
the Debtor prior to the Confirmation Date.


         T. Only One Plan. The Plan is the only plan of reorganization of the
Debtor pending before this Court or any other court.

         U. No Tax Avoidance. The primary purpose of the Plan is not the
avoidance of taxes or the application of Section 5 of the Securities Act of
1933, as amended.

         V. Assumed Executory Contracts and Unexpired Leases. With respect to
each executory contract and unexpired lease of the Debtor that is being assumed
by Reorganized TransTexas pursuant to Section 8.01 of the Plan, either (i)
there have been no defaults under such executory




ORDER CONFIRMING DEBTOR'S SECOND AMENDED,
MODIFIED AND RESTATED PLAN OF REORGANIZATION                             Page 13

contract or unexpired lease, other than defaults of the nature set forth in
Section 365(b)(2) of the Bankruptcy Code or (ii) with respect to defaults other
than those specified in such Section, the Debtor (a) has cured, or provided
adequate assurance that Reorganized TransTexas will cure, such defaults on or
as soon as practicable after the Effective Date, and (b) has compensated, or
provided adequate assurance that Reorganized TransTexas will compensate, on or
as soon as practicable after the Effective Date, parties to such executory
contracts or unexpired leases for any actual pecuniary loss resulting from such
default, and the reorganization of the Debtor pursuant to the Plan and this
Court's finding in Paragraph Q above provide adequate assurance of future
performance under the applicable executory contract or unexpired lease.


         W. Releases and Indemnifications. The provisions of the Plan and other
provisions in the Confirmation Order dealing with releases, injunctions and
indemnification, specifically Sections 5.04, 9.01, 9.02, 11.04 and 12.15 are in
the best interest of the Debtor, Reorganized TransTexas and all of the holders
of Claims and Interests receiving a Distribution in that, among other things,
such provisions have reduced the expenses of Reorganized TransTexas by allowing
it to reduce the cost and expense it would otherwise incur in connection with
providing insurance coverage to its officers and directors.


         X. Modification to Plan. The modifications to the Plan set forth in
the Debtor's Second Amended, Modified and Restated Plan of Reorganization and
blacklined against the Debtor's Second Amended Plan of Reorganization and Filed
by the Debtor on February 2, 2000, and the Notice of Technical Modifications,
Filed by the Debtor on February 2, 2000, as amended or modified prior to the
entry of this Confirmation Order, complied in all respects with Section 1127(a)




ORDER CONFIRMING DEBTOR'S SECOND AMENDED,

of the Bankruptcy Code and, in accordance with Bankruptcy Rule 3019, do not
adversely change the treatment of the Claim of any Creditor or the Interest of
any equity security holder who has not accepted in writing such amendments. The
notice of such amendments was due and adequate under the circumstances of the
Chapter 11 Case and such modifications do not require additional disclosure
under Section 1125 of the Bankruptcy Code or the resolicitation of acceptances
or rejections under Section 1126 of the Bankruptcy Code, nor do they require
that the holders of Claims or Interests be afforded an opportunity to change
previously cast acceptances or rejections of the Plan.


         Y. Good Faith Solicitation. Based upon the record before the Court,
the Debtor, the Creditors' Committee, the Entities serving on the Bondholder
Committee at any time during the Chapter 11 Case, the Bondholder Lenders, the
SubDebt Committee, GMAC, Firstar, Bank One, the Production Payment Holder, the
Post Confirmation Credit Facility Lenders and any of their respective officers,
directors, partners, employees, members, agents, advisors, affiliates,
underwriters or investment bankers, and any other professional persons employed
by any of them (the "Exculpated Persons") have acted in good faith in
connection with and relating to the formulation, negotiation, solicitation,
implementation, confirmation and consummation of the Plan, the Disclosure
Statement and any Plan Related Documents, and have acted in compliance with the
applicable provisions of the Bankruptcy Code and are entitled to the
protections afforded by Section 1125(e) of the Bankruptcy Code and the
exculpatory and injunctive provisions in Article IX of the Plan (to the extent
provided therein).

         Z. Retention of Jurisdiction. The Court may properly retain
jurisdiction over the matters set forth in Article XII of the Plan.
Notwithstanding anything in the Plan to the contrary, the Court shall not
retain jurisdiction with respect to Priority Tax Claims or Administrative
Expense Tax Claims except for: (i) resolving the amount of any Tax Claims
arising prior to Confirmation, and (ii) enforcing the discharge provisions of
the Plan after Confirmation.


         FINDING THAT THE PLAN IS CONFIRMABLE BASED UPON, AMONG OTHER THINGS,
ALL OF THE ABOVE-STATED FINDINGS OF FACT AND CONCLUSIONS OF LAW, AND GOOD CAUSE
APPEARING THEREFOR, THE COURT HEREBY ORDERS THAT:

         5. Plan Related Documents Approved. The form, terms and provisions of

and whether such Claim is known, unknown, fixed, contingent, matured,
unmatured, liquidated or unliquidated.


         7. Authorizations Under Delaware Law. Subject to the provisions of the

alter or terminate its existence (whether by merger or otherwise) as provided
by, and in conformity with, applicable state law.


         8. Binding Effect. The provisions of the Plan and this Confirmation

on or before the Effective Date (other than those Claims, Interests and
Encumbrances of the Bondholder Lenders under the Extended DIP Facility and GMAC
under the GMAC Post Confirmation Agreement), and (b) from and after the
Effective Date, Reorganized TransTexas may operate its business free from any
restrictions imposed by the Bankruptcy Code or by prior orders of this Court.


         10. Survival of Provisions of Final Financing Order Until Effective

Confirmation Order pursuant to Section 1142(a) of the Bankruptcy Code, the
Obligations under and as defined in the Bondholders DIP Facility (the "DIP
Obligations") and the rights, liens, priorities and other protections provided
to the Bondholder Lenders under and as defined in the Bondholder DIP Facility
and the Final Order Pursuant to 11 U.S.C. sections 364(c) and (d) of the
