                   Not applicable.

ITEM 2.            ACQUISITION OR DISPOSITION OF ASSETS.

                   Prior to December 15, 1998, TransAmerican Refining
                   Corporation, a Texas corporation ("TARC" or the "Company")
                   owned a refinery located in the Gulf Coast region along the
                   Mississippi River approximately 20 miles from New Orleans,
                   Louisiana. As a result of the Transaction (described below),
                   the Company no longer owns the refinery, but maintains a
                   non-controlling equity interest in TCR Holding Corporation, a
                   Delaware corporation ("TCR Holding"). TCR Holding owns a
                   controlling interest in TransContinental Refining
                   Corporation, a Delaware corporation ("TransContinental"), the
                   corporation that owns the refinery. TransContinental intends
                   to operate existing units and to complete construction of 
                   additional units.

                   The following Transaction was consummated on December 15,
                   1998 in order to provide additional capital for construction
                   of the refinery. The Transaction included the following:

                   (i)   The issuance by TARC of $150 million aggregate
                         principal amount of its 15% Senior Secured Notes due

                         Lenders");

                   (ii)  the transfer by TARC to TCR Holding of substantially
                         all of its assets (the "Refinery Assets") in exchange
                         for (x) all of the capital stock of TCR Holding, which

                         debt secured by certain tank storage and terminaling

                         Notes due 2003 (the "TEC Notes") and certain of the
                         holders of the TARC Subordinated Notes (together with
                         the TEC Holders, the "Purchasers") of TCR Repurchasable
                         Preferred Stock representing 30.0% of the Residual
                         Equity of TCR Holding and TCR Non-Repurchasable
                         Preferred Stock representing 29.6% of the Residual
                         Equity of TCR Holding. Affiliates of Trust Company of

                         purchase warrants (the "TARC Warrants") in exchange for
                         such TARC Warrants. "Residual Equity" means the
                         interest of the indicated stockholders in the assets of
                         TCR Holding upon a liquidation or winding up of TCR
                         Holding, which interest is subject to the prior payment
                         of the liquidation preference of the TCR Voting
                         Preferred Stock and the TCR Non-Voting Preferred Stock;

                         interest by TEC to secure the TEC Notes, the grant by
                         TCR Holding to TEC of a security interest in the common
                         stock of TransContinental to secure the TARC Working
                         Capital Loan, the collateral assignment of such
                         security interest to secure the TEC Notes, and the
                         provision in the TCR Voting Preferred Stock of the
                         right of holders of such stock in certain circumstances
                         to require TCR Holding to sell common stock of
                         TransContinental held by TCR Holding, or any assets
                         received on exchange or sale therefor, and apply the
                         proceeds to reduce the liquidation preference and
                         certain accrued but unpaid dividend amounts on the TCR
                         Voting Preferred Stock; and

                   (vi)  the purchase from TransContinental by the New Lenders
                         of TransContinental's 6% Participating Preferred Stock
                         ("TransContinental Preferred Stock").

                   As part of the Transaction, (i) the holders of TCR Holding
                   capital stock entered into a stockholders agreement providing
                   for the election of two nominees of TARC, two nominees of the
                   TCW Affiliates and one nominee of an affiliate of one of the
                   Purchasers as directors of TCR Holding and the election of
                   two nominees of TARC and two nominees of the TCW Affiliates
                   as directors of TransContinental, (ii) the stockholders of

                   nominee of an affiliate of one of the Purchasers) and four
                   nominees of TCR Holding as directors of TransContinental,
                   (iii) the holders of the TransContinental Preferred Stock
                   would have the right to elect a majority of the directors of
                   TransContinental if either of such stockholders agreements
                   has been breached, is not being complied with or has been
                   adjudicated to be unenforceable, (iv) TransAmerican Natural
                   Gas Corporation ("TransAmerican"), as the sole stockholder of
                   TEC, and TEC, as the sole stockholder of TARC, would agree to
                   elect a representative of the TCW Affiliates as a director of
                   TEC and of TARC, respectively, (v) TCR Holding and
                   TransContinental would enter into registration rights

                   respective securities being issued to the New Lenders in the
                   Transaction, (vi) TCR Holding and TransContinental,
                   respectively, would enter into services agreements with
                   TransTexas Gas Corporation ("TransTexas") providing for

                   TransContinental by TransTexas and (vii) TEC or one of its
                   affiliates will be granted certain rights to repurchase
                   shares of the TCR Repurchasable Preferred Stock (which would
                   become voting stock upon exercise of such rights), which
                   could result in TEC and its affiliates owning a majority of
                   the capital stock of TCR Holding and being entitled to elect
                   a majority of the directors of TCR Holding and, indirectly,
                   TransContinental. Such repurchase rights would only be
                   exercisable after the Notes, the TEC Notes and the TARC
                   Subordinated Notes have been fully repaid and certain
                   financial performance tests have been met. In addition, TARC
                   would have the right to repurchase the shares of TCR
                   Non-Voting Common Stock issued to the TCW Affiliates pursuant
                   to the Transaction for $5 million at any time during the
                   two-year period commencing with the Issue Date (as defined);
                   provided, however, that if the TCR Voting Preferred Stock
                   remains outstanding after July 31, 1999, TARC will have the
                   option to repurchase such stock at a nominal cost.

                   All of the above transactions, as well as other agreements
                   and transactions necessary to facilitate or related to the
                   foregoing, are referred to as the "Transaction."

                  (i) The Indenture and the consummation of the transactions
contemplated thereby, including the issuance of the Notes, have been duly and
validly authorized by all necessary corporate action (including, without
limitation, required stockholder approvals, if any) of TARC, and when the

considered in a proceeding in equity or at law), and will be in sufficient form
for qualification under the Trust Indenture Act of 1939, as amended (the "TRUST
INDENTURE ACT") and the rules and regulations of the Commission promulgated
thereunder. When the TARC Assumption Agreement has been executed and delivered,
the Indenture will be a legal, valid and binding agreement of TCR Holding,
enforceable against TCR Holding in accordance with its terms, except as such

any officer, director, employee or holder of capital stock of TEC, TARC, TCR
Holding or TransContinental or any of their affiliates. Giving effect to the use
of proceeds substantially contemporaneously with the Closing, none of TEC, TARC,
TCR Holding or TransContinental is, or with the giving of notice or lapse of
time or both would be, in violation of or in default under, nor will the
execution or delivery of this Agreement or any of the other Transaction
Documents or the consummation of the transactions contemplated hereby or thereby
(including, without limitation, the issuance of the Securities and the
Reorganization) result in a violation of, or constitute a default under, the
Certificates or Articles of Incorporation, by-laws or other governing documents

concurrently with, the Closing), except for such breaches or violations of or
such defaults under any such Contract as would not (after giving effect to the
use on the Closing Date of proceeds from the sale of the Securities),
individually or in the aggregate, have a Material Adverse Effect; nor will the
execution, delivery and performance by TEC, TARC, TCR Holding and
TransContinental of their respective obligations hereunder or thereunder cause a
material violation of any law, rule, administrative regulation, License (as
defined in paragraph (n) below) or decree of any court, governmental agency or
body having jurisdiction over TEC, TARC, TCR Holding or TransContinental or any
of their respective properties, or result in the creation or imposition of any
Lien (other than Permitted Liens) upon any property or asset of TEC, TARC, TCR
Holding or TransContinental, except, in each case, as would not, individually or
in the aggregate, have a Material Adverse Effect. TEC, after giving effect to
the use on the Closing Date of the proceeds from the sale of the Securities, is
not in default under any loan agreement.

                  (k) Other than a consent required for the assignment of the

consent, approval, authorization or order of, or filing or registration or
qualification with, any court or governmental agency or body or financial
institution, or any other party under any Contract will be required as of the
Closing Date on the part of any of them for the authorization, issuance, sale
and delivery of the Securities, or the execution, delivery and performance by
TEC, TARC, TCR Holding and TransContinental, of their respective obligations
under this Agreement or any of the other Transactions Document or the
consummation of the transactions contemplated hereby or thereby (including,
without limitation, the Reorganization), except (1) as have been obtained, (2)
as may be required under the "Blue Sky" laws of the various states in connection
with the offer and sale of the Securities and (3) as may be required by the
Securities Act, the "Blue Sky" laws of the various states, the Trust Indenture

Inc. ("NASD"), in conjunction with an exchange offer for, or registered resale
of, the Securities pursuant to the A/B Exchange Registration Rights Agreement,
the Registration Rights Agreements and the qualification of the Indenture and
the Trustee.

                  (l) Except for this Agreement, the A/B Exchange Registration
Rights Agreement, and the Registration Rights Agreements and registration rights
with respect to common stock purchase warrants of TARC and TARC's 16% Senior
Subordinated Notes due 2003, none of TARC, TCR Holding and TransContinental has
entered into any pending agreement (i) to register its securities under the
Securities Act or (ii) other than as contemplated herein, to purchase or offer
to purchase any securities of TARC, TCR Holding, TransContinental or any of
their respective affiliates.

                  (m) Upon execution and delivery thereof, the Security
Agreement will create, in favor of the Trustee (as defined therein), for the
benefit of the holders of the Notes, a valid grant of a first priority security
interest in the Personal Property Collateral and the proceeds thereof and, upon
the filings or the recording required by the Security Agreement, the Trustee
will have, other than with respect to Permitted Liens, a first priority
perfected security interest in the Personal Property Collateral. Upon execution
and delivery thereof, the Company Mortgage will create, in favor of the New
Lenders, a valid grant of a security interest in the Real Property Collateral
and the proceeds thereof and, upon the filings or the recording required by such
instrument, the New Lenders will have, other than with respect to Permitted
Liens, a valid first priority perfected security interest in such collateral.
Upon the execution and delivery thereof,



                                      -9-
<PAGE>   11

the Construction Collateral and Disbursement Agreement will create, in favor of
the Trustee (as defined therein), for the benefit of the holders of the Notes, a
valid grant of a first priority security interest in that portion of the
Personal Property Collateral that the agreement purports to cover and the
proceeds thereof and, when the Trustee becomes identified in the records of a
securities intermediary, the Trustee will have a first priority perfected
security interest in such Personal Property Collateral.

                  (n) Schedule 2(n) contains a true and complete list of all
licenses, certificates, permits, consents, orders, authorizations and approvals
(collectively, "LICENSES") used in and material, individually or in the
aggregate, to the Business or operations of TARC, and, following consummation of
the transactions contemplated by this Agreement and the other Transaction
Documents (including the Reorganization), TCR Holding or TransContinental. TARC,
TCR Holding and TransContinental hold and will hold, as the case may be, all
material Licenses from governmental authorities that are necessary to the
conduct of Businesses and to enable all Real Property and Improvements (as
described in the Company Mortgage and including the Tank Storage Facility) to be
lawfully occupied and used for all of the purposes for which they are currently
occupied and used and as expected to be occupied and used upon completion of the
Refinery; such Licenses are in full force and effect and no proceeding has been
instituted or, to the knowledge of TARC, TCR Holding or TransContinental, is
threatened, pending or contemplated which in any manner affects or draws into
question the validity or effectiveness thereof; such Licenses contain no
restrictions that are or could be reasonably be expected to be materially
burdensome to the conduct of the Business; and to the knowledge of TARC, TCR
Holding and TransContinental, no event has occurred that permits (nor has an
event occurred that with notice or lapse of time or both would permit) the
modification, revocation or termination of such Licenses or that might result in
any other material impairment of the rights of TARC, TCR Holding or
TransContinental therein other than modifications, revocations or terminations
that would not, individually or in the aggregate, have a Material Adverse
Effect.

                  (o) Schedule 2(o) contains a true and complete list of all the
patent rights, inventions, trademarks, service marks, trade names and copyrights
used in and material, individually or in the aggregate, to the Business or
operations of TARC and, following consummation of the transactions contemplated
by this Agreement and the other Transaction Documents (including the
Reorganization), TCR Holding and TransContinental (the "INTELLECTUAL PROPERTY").
No other Intellectual Property is used or is necessary to construct the Refinery
and to operate the Refinery and the other Transferred Assets, and none of TARC,
TCR Holding and TransContinental has received any written notice or is otherwise
aware of any infringement of or conflict with asserted rights of others with
respect to, any Intellectual Property which, individually or in the aggregate,
could reasonably be expected to have a Material Adverse Effect. There are no
restrictions on the direct or indirect transfer of any such Intellectual
Property or any Contract, or any interest therein, in respect of such
Intellectual Property held by TARC or to be held by TCR Holding or
TransContinental following consummation of the Reorganization.

                  (p) Each of the Improvements listed on Schedule 2(p) have been
sufficiently constructed in accordance with the Plans (as defined in the
Indenture and existing on the date hereof and the Closing Date), and each of the
Improvements comprising the Tank Storage Facility have been sufficiently
constructed so that, in each case, it may be operated for its intended purpose.
All water, gas, electrical, steam, compressed air, telecommunications, sanitary



                                      -10-

and storm sewage lines and systems and other similar systems necessary for the
operation of the Real Property and Improvements are installed and operating and
are sufficient to enable the Real Property and Improvements to continue to be
used and operated in the manner currently being used and operated, such systems
as are anticipated to be installed and operated in accordance with the Plans
will, upon such installation in accordance with the Plans, be sufficient to
enable the Real Property and Improvements to be used and operated in the manner
currently contemplated upon completion of the Capital Improvement Program (as
defined in the Indenture, described in the Offering Circulars and existing on
the date hereof (the "CAPITAL IMPROVEMENT PROGRAM"), and none of TARC, TCR
Holding and TransContinental has any knowledge of any factor or condition that
could result in the termination or material impairment of the furnishing
thereof. No Improvement or portion thereof is or, upon consummation of the
Reorganization and completion of the Refinery in accordance with the Plans, will
be, dependent for its access, operation or utility on any land, building or
other Improvement not included in the Real Property or subject to easements,
servitudes or similar rights in favor of TARC.

                  (q) None of TARC, TCR Holding and TransContinental has
received any notice, or has any knowledge, of any pending, threatened or
contemplated condemnation proceeding affecting any Real Property or Improvements
or any part thereof or of any sale or other disposition of any Real Property or
Improvements or any part thereof in lieu of condemnation.

                  (r) No portion of any Real Property or Improvements has
suffered any material damage by fire or other casualty loss which has not
heretofore been completely repaired and restored to its original condition.

                  (s) As of the date hereof, no party to any reciprocal easement
agreement affecting any of the Real Property or Improvements is, and as of the
Closing Date, no such party will be, in material default thereunder and no event
has, or will have, occurred which, with the giving of notice or lapse of time or
both, would constitute a default thereunder. All maintenance payments with
respect to such reciprocal easement agreements which were due and payable prior
to the date hereof have been paid.

                  (t) TARC has provided the Beneficiary (as defined in the
Company Mortgage) a true, correct and complete listing of the real property tax
bills for the Real Property Collateral and all other real property owned by
TARC, TCR Holding or TransContinental for the current tax year and bills with
respect to any special assessments affecting any of such Real Property. All real
property taxes and special assessments with respect to such Real Property which
were due and payable prior to the date hereof have been paid in full. TARC has
not received any written notice of any special assessment action or proceeding
or real property tax reassessment with respect to the Real Property.

                  (u) The Real Property and Improvements are in compliance with
all building, fire, zoning, environmental and other ordinances and regulations
applicable thereto except to the extent that any failure to so comply could not
adversely affect the conduct of the Business or the completion or operation of
the Refinery.

<PAGE>   13

                  (v) Except as disclosed in Schedule 2(v), the Real Property
and Improvements and the present use and condition thereof do not violate, in
any material respect, any applicable deed restrictions or other covenants,
restrictions or agreements, site plan approvals, zoning or subdivision
regulations or urban redevelopment plans applicable thereto, as modified by any
duly issued variances. Except as disclosed in Schedule 2(v), no building or
Improvement which is part of any of the Real Property encroaches, in any
material respect, upon any property owned by any adjacent landowner or upon any
real property interest held by any other individual, corporation, partnership,
limited liability company or other legal entity or association ("PERSON") with
respect to any of such real property.

                  (w) No notices of violation of law or municipal ordinances or
of federal, state, county or municipal or other governmental agency regulations,
orders or requirements relating to any of the Real Property or Improvements that
have not been completely cured have been entered or received by TARC, TCR
Holding or TransContinental, and TARC, TCR Holding and TransContinental have no
reason to believe that any such notice may or will be entered.

                  (x) All water, sewer, gas, electricity or telephone and other
utilities serving the Real Property and Improvements are supplied directly to
the Real Property and Improvements by facilities of public utilities except as
set forth in Schedule 2(x).

                  (y) Except as disclosed in both the Disclosure Statements
hereto and except for ordinary course business lawsuits which could not
reasonably be expected to result in a Material Adverse Effect, there are no
actions or proceedings (zoning or otherwise) or governmental investigations
pending, or, to the knowledge of TARC, TCR Holding or TransContinental,
threatened against or relating to any of such Persons or the property of such
Persons, nor, to the knowledge of TARC, TCR Holding and TransContinental, is
there any basis for such action.

                  (z) None of TARC, TCR Holding and TransContinental has any
knowledge of any federal, state, county or municipal plans to change any
highways or road systems in the vicinity of any of the Real Property or to
restrict or change access from any such highway or road to any of the Real
Property or of any pending or threatened condemnation of any of the Real
Property or Improvements or any parts thereof or of any plans for improvements
which might result in a special assessment against any of the Real Property or
Improvements.

                  (aa) The foundation, structure and roof of each building and
improvement comprising a part of the Real Property and Improvements are sound in
all material respects.

                  (bb) The construction of the Refinery and the operation of the
other Transferred Assets has been and, assuming the Refinery is completed and
operated in accordance with the Plans, will be (giving effect to any waivers or
variances which have been obtained and remain in effect or the obtaining of
those Licenses that appear on Schedule 2(j) under the caption "Permits in
Progress" (the "PENDING PERMITS")) in compliance with all applicable state,
federal and local laws, regulations, ordinances, standards, statutes, orders,
rules and other regulations, where the failure to comply therewith could have a
Material Adverse Effect or materially impair operation of the Refinery as it is
contemplated to be operated as described in the Disclosure Statements. Neither
TARC, TCR Holding nor TransContinental has any reason to believe that



                                      -12-
<PAGE>   14

the Pending Permits will not be approved by the relevant licensing authority.
Under applicable zoning and use laws, ordinances, rules and regulations, all
necessary subdivision approvals have been obtained for the construction of the
Refinery, except to the extent the failure to have or obtain any such approval
would not have a Material Adverse Effect.

                  (cc) As of October 31, 1998, the Company did not have
obligations outstanding in excess of $59,000,000 consisting of accounts payable
and other short-term obligations incurred in connection with the Capital
Improvement Program. TARC, TCR Holding and TransContinental estimate that as of
October 31, 1998, additional construction costs of $138,000,000 to $159,000,000
(in addition to such accounts payable) were required to complete the Capital
Improvement Program. TARC, TCR Holding and TransContinental have no reason to
believe that such estimate is inaccurate.

                  (dd) Except for matters specifically reasonably identifiable
in the Disclosure Documents or otherwise disclosed in writing to the TCW Funds
and the Purchaser as exceptions to this representation in this Agreement;

                          (i) each of TARC, TCR Holding and TransContinental
and, to the best knowledge of TARC, TCR Holding and TransContinental, any Person
for whom any of the foregoing are or may be 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 Licenses required under the Environmental Laws with respect to
the operation of the business, property and assets of TARC, TCR Holding and
TransContinental or any such Person, and compliance with the terms and
conditions thereof and (3) any federal, state, local or foreign approvals
pursuant to any Environmental Laws that pertain or relate to the transactions
contemplated by this Agreement (including, without limitation, the issuance of
the Securities and the Reorganization) except for such failures to comply as
could not reasonably be expected to result in costs, fines, penalties or other
losses in excess of $200,000 individually or $1 million in the aggregate;

                         (ii) none of TARC, TCR Holding and TransContinental has
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; none of TARC, TCR Holding and
TransContinental has any liability under any Environmental Law; and, to the best
knowledge of each of TARC, TCR Holding and TransContinental, there are no past
or present actions, activities, circumstances, conditions, events or incidents

TARC, TCR Holding and TransContinental (or any Person for whom TARC, TCR Holding
and TransContinental is or may be responsible by law or contract) with
applicable Environmental Laws in the future except for failures to comply (or
related notices of claims) as could not reasonably be expected to result in



                                      -13-

costs, fines, penalties or other losses in excess of $200,000 individually or
$1 million in the aggregate;

                         (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, 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 TARC, TCR Holding and TransContinental, threatened against

that could reasonably be expected to form the basis of any Environmental
Liability against TARC, TCR Holding and TransContinental exceeding, in the case
of Environmental Liabilities relating to violations of Environmental Laws or as
could not reasonably be expected to result in costs, fines, penalties or other
losses in excess of $200,000 individually or $1 million in the aggregate;

                         (v) no real property or facility owned, operated,

transactions are recorded as necessary to permit preparation of financial
statements in conformity with GAAP and to maintain accountability for assets;
(iii) access to assets is permitted only in accordance with management's general
or specific authorization; and (iv) the recorded accountability for assets is
compared with existing assets at reasonable intervals and appropriate action is
taken with respect to any differences.

                  (gg) Immediately following consummation of the transactions
contemplated by this Agreement and the other Transaction Documents (including
without limitation, the issuance and sale of the Securities and the
Reorganization), TransContinental will, in the opinion of each of TARC, TCR
Holding and TransContinental, be Solvent. As used herein, the term "SOLVENT"
means, with respect to TransContinental on such date (i) the fair value and
present fair saleable value of TransContinental's assets would exceed
TransContinental's known liabilities (including known contingent liabilities),
(ii) TransContinental should be able to pay its debts and liabilities as they
become absolute and mature and (iii) the capital remaining in TransContinental
would not be unreasonably small for the Business.

                  (hh) None of TARC, TCR Holding or TransContinental is in

to which it may be subject, which violation could have, individually or in the
aggregate, a Material Adverse Effect.

insurers of recognized financial responsibility against such losses and risks
and in such amounts as are prudent and customary in the businesses in which they
are engaged and the Contracts governing such insurance may be freely assigned to
each of TCR Holding and TransContinental pursuant to the Reorganization; since
1991, TARC has not failed to obtain insurance coverage of any nature by reason
of the refusal of insurers to provide such coverage; and TARC does not have any
reason to believe that it, TCR Holding or TransContinental would be unable to
renew existing insurance coverage from similar insurers as may be necessary to
continue the Business at a cost that would not have, individually or in the
aggregate, a Material Adverse Effect.

                  (jj) Except as disclosed in each of the Disclosure Statements
as of their respective dates, as of the date hereof and as of the Closing Date,
none of TARC, TCR Holding and TransContinental had, has or will have, as the
case may be, violated any Federal, state or local law relating to discrimination
in employment nor any applicable wage or hour laws, nor any provisions of the
Employee Retirement Income Security Act of 1974, as amended, or the rules and
regulations promulgated thereunder ("ERISA"), nor has TARC, TCR Holding or
TransContinental engaged in any unfair labor practice, which in each case could
reasonably be expected to result, individually or in the aggregate, in a
Material Adverse Effect. Except as disclosed in each of the Disclosure
Statements as of their respective dates, as of the date hereof and as of the
Closing Date, there was, is or will be, as the case may be (i) no unfair labor
practice complaint pending against TARC or, to the knowledge of TARC, TCR
Holding and TransContinental, threatened against any of them, before the
National Labor Relations Board or any state or local labor relations board and
neither TARC, TCR Holding nor TransContinental is party to any collective
bargaining agreement, (ii) no significant strike, labor dispute, slowdown

or stoppage pending against, TARC, TCR Holding or TransContinental, or, to the
knowledge of, TARC, TCR Holding and TransContinental, threatened against any of
them and (iii) to the knowledge of, TARC, TCR Holding and TransContinental, no
union representation question existing, with respect to employees of TARC, TCR
Holding or TransContinental, except (with respect to any matter specified in
clause (i), (ii) or (iii) above, individually or in the aggregate) such as would
not have a Material Adverse Effect, and, TARC, TCR Holding and TransContinental
have no reason to believe that the relationship of TARC, TCR Holding and
TransContinental with their employees is likely to have, individually or in the
aggregate, a Material Adverse Effect.

                  (kk) Subsequent to the respective dates as of which
information is given in each of the Disclosure Statements (i) TARC, TCR Holding
and TransContinental have not incurred any material liability or obligation,
direct or contingent, nor entered into any material transaction not in the
ordinary course of business except as described in or contemplated by this
Agreement or the Disclosure Statements; and (ii) there has not been any material
adverse change in the condition (financial or otherwise), results of operations,
business, prospects, net worth or assets of TARC, TCR Holding or
TransContinental, from the date as of which information is given in each of the
Disclosure Statements.

                  (ll) None of, TARC, TCR Holding, TransContinental and any of
their respective officers, directors or employees has employed any broker or
finder or incurred any liability for any brokerage fees, commissions or finders'
fees in connection with the issuance of the Securities or the consummation of
the Reorganization, other than to the New Lenders.

                  (mm) None of, TARC, TCR Holding, TransContinental nor any
agent thereof acting on behalf of any of them has taken, and none of them will
take, any action that might cause this Agreement or the issuance or sale of the
Securities and the use of the proceeds therefrom to violate Section 7 of the
Securities Exchange Act of 1934, as amended (the "EXCHANGE ACT"), or any
regulation promulgated thereunder, 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, in
each case as in effect on the date hereof or as the same may hereafter be in
effect on the Closing Date.

                  (nn) Assuming that the representations, warranties and
covenants of the New Lenders and the Purchaser, respectively, contained in this
Agreement are true and correct and have been and will be complied with, no
registration of the Securities under the Securities Act or qualification of an
indenture under the Trust Indenture Act is required for the offer, sale and
delivery of any of the Securities to either the New Lenders or the Purchaser,
respectively, or the initial resale thereof in the manner contemplated by this
Agreement.

                  (oo) In connection with the offer and sale of the Securities,
none of TEC, TARC, TCR Holding or TransContinental have taken nor will take,
directly or indirectly, any action prohibited by Regulation M under the Exchange
Act.

                  (pp) The Securities satisfy the requirements set forth in Rule
144A(d)(3) under the Securities Act.

representation, warranty, covenant or agreement in this Agreement or (ii) any
action taken or inaction on the part of any of TEC, TARC, TCR Holding or
TransContinental in connection with the issuance and sale of the Securities or
the



                                      -32-

consummation of the Reorganization; provided that neither TEC's nor TARC's
indemnity shall extend to losses claims, damages and liabilities breaches caused
by, arising out of or based upon breaches by TCR Holding and TransContinental,
which occur as a result of action taken or inaction after the Closing Date).

                  (c) If any suit, action, proceeding (including any
governmental or regulatory investigation), claim or demand shall be instituted
or asserted against any person in respect of which indemnity may be sought
pursuant to either of paragraph (a) or (b) above, such person (hereinafter
called the "INDEMNIFIED PARTY") shall promptly notify the person against whom
such indemnity may be sought (hereinafter called the "INDEMNIFYING PARTY") in
writing; provided, however, that the failure to so notify the indemnifying party
shall not relieve it of any obligation or liability that it may have hereunder
or otherwise (unless and only to the extent that such failure directly results
in the loss or compromise of any material rights or defenses by the indemnifying
party and the indemnifying party was not otherwise aware of such action or
claim). The indemnifying party, upon request of the indemnified party, shall
assume the defense thereof, including the employment of counsel reasonably
satisfactory to the indemnified party to represent the indemnified party and any
others that the indemnifying party may designate in such proceeding and shall
pay the reasonable fees and disbursements of such counsel related to such
proceeding. In any such action or proceeding, any indemnified party shall have
the right to retain its own counsel, but the fees and expenses of such counsel
shall be at the expense of such indemnified party unless (i) the indemnifying
party and the indemnified party shall have mutually agreed in writing to the
contrary, (ii) the indemnifying party shall have failed within a reasonable
period of time to retain counsel reasonably satisfactory to the indemnified
party, or (iii) the named parties to any such proceeding (including any
impleaded parties) include both the indemnifying party and the indemnified party
or any affiliate of either and representation of both parties by the same
counsel would be inappropriate due to actual or potential differing interests
between them. It is understood that, unless there exists a conflict among
indemnified parties, the indemnifying party shall not, in connection with any
one such proceeding or separate but substantially similar related proceedings in
the same jurisdiction, be liable for the fees and expenses of more than one
separate firm (in addition to any appropriate local counsel) for all indemnified
parties, and that all such fees and expenses shall be reimbursed promptly after
the receipt of the invoice therefor as they are incurred. Any such separate firm
shall be designated in writing by (i) the TCW Funds, with respect to the New
Lenders, their affiliates and their respective successors and assigns and (ii)
the Purchaser, with respect to the Purchasers, its affiliates and their
respective successors and assigns. The indemnifying party shall not be liable
for any settlement of any proceeding effected without its prior written consent,
but if settled with such consent or if there be a final judgment for the
plaintiff for which the indemnified party is entitled to indemnification
pursuant to this Agreement, the indemnifying party agrees to indemnify and hold
harmless each indemnified party from and against any loss or liability by reason
of such settlement or judgment. No indemnifying party shall, without the prior
written consent of the indemnified party (which consent shall not be
unreasonably withheld), effect any settlement or compromise of any pending or
threatened proceeding in respect of which any indemnified party is or could have
been a party and indemnity could have been sought hereunder by such indemnified
party.

                  (d) To the extent the indemnification provided in paragraph
(a) or (b) of this Section 8 is for any reason unavailable to (other than by
reason of exceptions provided therein),



                                      -33-
<PAGE>   35

or insufficient to hold harmless, an indemnified party in respect of any losses,
claims, damages, liabilities or expenses (or actions in respect thereof)
referred to therein, then each indemnifying party under such paragraphs, in lieu
of indemnifying such indemnified party thereunder and in order to provide for
just and equitable contribution, shall contribute to the amount paid or payable
by such indemnified party as a result of such losses, claims, damages or
liabilities in such proportion as is appropriate to reflect (i) the relative
benefits received by TEC, TARC, TCR Holding and TransContinental on the one hand
and the New Lenders or the Purchaser on the other hand from the offering of the
Securities or (ii) if the allocation provided by clause (i) above is not
permitted by applicable law, not only such relative benefits but also the
relative fault of TEC, TARC, TCR Holding and TransContinental on the one hand
and the New Lenders or the Purchaser on the other hand in connection with the
statements or omissions or alleged statements or omissions that resulted in such
losses, claims, damages or liabilities (or actions in respect thereof), as well
as any other relevant equitable considerations. The relative benefits received
by TEC, TARC, TCR Holding and TransContinental on the one hand and the New
Lenders or the Purchaser on the other hand in connection with the offering of
the Securities shall be deemed to be in the same proportion as the total
proceeds from the offering of the Securities (net of discounts and commissions
but before deducting expenses) received by TARC, TCR Holding and
TransContinental bears to the fees received by the New Lenders or the Purchaser
who have received any such fees in respect thereof. The relative fault of TEC,
TARC, TCR Holding and TransContinental on the one hand and the New Lenders or
the Purchaser on the other hand shall be determined by reference to, among other
things, whether the untrue or alleged untrue statement of a material fact or the
omission or alleged omission to state a material fact relates to information
supplied by TEC, TARC, TCR Holding and TransContinental on the one hand or by
the New Lenders or the Purchaser on the other hand, the parties' relative
intent, knowledge, access to information and opportunity to correct or prevent
such statement or omission, and any other equitable considerations appropriate
in the circumstances.

                  (e) TEC, TARC, TCR Holding, TransContinental and the New
Lenders and the Purchaser agree that it would not be just and equitable if
contribution pursuant to Section 8(d) were determined by pro rata allocation or
by any other method of allocation that does not take account of the equitable
considerations referred to in Section 8(d). The amount paid or payable by an
indemnified party as a result of the losses, claims, damages or liabilities (or
actions in respect thereof) referred to in Section 8(d) shall be deemed to
include, subject to the limitations set forth above, any reasonable legal or
other expenses actually incurred by such indemnified party in connection with
defending or investigating any such action or claim. Notwithstanding the
provisions of Section 8(d), no New Lender or Purchaser shall be required to
contribute any amount in excess of the amount by which the total price at which
the Securities purchased and resold by it exceeds the amount of any damages that
the New Lender or the Purchaser has otherwise been required to pay or has paid
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.

                  The indemnity and contribution provisions contained in this
Section 8 and the representations and warranties of TEC, TARC, TCR Holding and
TransContinental contained in this Agreement shall remain operative and in full
force and effect regardless of (i) any termination of this Agreement, (ii) any
investigation made by or on behalf of the New Lenders or



                                      -34-
<PAGE>   36

the Purchaser or any person controlling the New Lenders or the Purchaser or
under common control with or controlled by the New Lenders or the Purchaser or
by or on behalf of TEC, TARC, TCR Holding and TransContinental and their
respective officers, authorized representatives or directors or any person
controlling TEC, TARC, TCR Holding and TransContinental and (iii) acceptance of
and payment for any of the Securities or consummation of the Reorganization.

                  The indemnity and contribution agreements contained in this
Section 8 will be in addition to any liability that the indemnifying party or
parties may otherwise have to the indemnified party or parties referred to
above.

                  9. Termination and Survival.

                  (a) This Agreement may be terminated for any reason at any
time prior to the delivery and payment of the Securities on the Closing Date, as
the case may be, by the New Lenders or the Purchaser upon written notice of such
termination to TARC, if prior to such time (i) there has been, since the
respective dates as of which information is given in either of the Disclosure
Statements, (A) any material adverse change in the condition, (financial or
otherwise), results of operations, business, prospects, net worth or assets of
TARC, TCR Holding or TransContinental, whether or not arising in the ordinary
course of business or (B) except as contemplated by this Agreement, any material
transaction entered into by TARC, TCR Holding or TransContinental other than in
the ordinary course of business, or (ii) there has occurred any outbreak or
escalation of hostilities or other calamity or crisis or material change in
existing national or international financial, political, economic or securities
market conditions, the effect of which is such as to make it, in the judgment of
the New Lenders or the Purchaser, impracticable or inadvisable to purchase the
Securities or enforce contracts for the resale of Securities, or (iii) trading
generally on the New York Stock Exchange or quotations on The Nasdaq Stock
Exchange, either has been suspended, or minimum or maximum prices for trading
have been fixed, or maximum ranges for prices for securities have been required
by either of said organizations or by order of the Commission or any other
governmental authority or, if a banking moratorium has been declared, by either
Federal or New York authorities, or (iv) any downgrading shall have occurred in
the rating accorded the securities of TEC or TARC by any "nationally recognized
statistical rating organization," as that term is defined by the Commission for
purposes of Rule 436(g)(2) under the Securities Act.

                  (b) Notwithstanding any other provision of this Agreement,
this Agreement shall terminate if not consummated on or prior to December 15,
1998 unless the time for consummation of this Agreement is extended in a writing
by each of the parties to this Agreement.

                  (c) In the event of any such termination, the provisions of
Section 7 hereof, the indemnity agreement and contribution provisions set forth
in Section 8 hereof, and the provisions of Sections 10 and 15 hereof shall
remain in effect.

                  10. Representations, Warranties and Agreements to Survive
Delivery. All representations, warranties and agreements contained in this
Agreement, or contained in certificates of officers of TARC, TCR Holding or
TransContinental submitted pursuant hereto,



                                      -35-

including indemnity and contribution agreements, shall remain operative and in
full force and effect, regardless of any termination of this Agreement, or any
investigation made by or on behalf of the New Lenders or the Purchaser or any
person controlling the New Lenders or the Purchaser or by or on behalf of TARC,
TCR Holding, TransContinental or their respective officers or directors, and
shall survive acceptance of and payment for the Securities hereunder and
consummation of the Reorganization.

and (ii) TCR Holding will assume the Assumed Liabilities pursuant to (X) an
Assumption Agreement in the form of Schedule C hereto (the "Assumption

Liabilities as and to the extent provided in Section 1.02 (the Assumption

                  1.04 Further Assurances; Post-Closing Cooperation.

                  (a) At any time or from time to time after the Closing, at TCR
Holding's request and without further consideration, TARC shall execute and
deliver to TCR Holding such other instruments of sale, transfer, conveyance,

such other actions as TCR Holding may reasonably deem necessary or desirable in
order more effectively to transfer, convey and assign to TCR Holding, and to
confirm TCR Holding's title to, all of the Assets, and, to the full extent
permitted by Law, to put TCR Holding in actual possession and operating control
of the Refinery and the Assets and to assist TCR Holding in exercising all
rights with respect thereto, and otherwise to cause TARC to fulfill its
obligations under this Agreement. 

                  (b) Effective on the Closing Date, TARC hereby constitutes and
appoints TCR Holding the true and lawful attorney of TARC, with full power of
substitution, in the name of TARC or TCR Holding, but on behalf of TARC and for
the benefit of TCR Holding: (i) to demand and receive from time to time any and
all of the Assets and to make endorsements and give receipts and releases for
and in respect of the same and any part thereof; (ii) to institute, prosecute,
compromise and settle any and all Actions or Proceedings that TCR Holding may
deem proper in order to collect, assert or enforce any claim, right or title of
any kind in or to the Assets; (iii) to defend or compromise any or all Actions
or Proceedings in respect of any of the Assets; and (iv) to do all such acts and
things in relation to the matters set forth in the preceding clauses (i) through

                                       2
<PAGE>   6

the appointment hereby made and the powers hereby granted are coupled with an
interest and are not and shall not be revocable by it in any manner or for any
reason. TARC shall execute and deliver to TCR Holding at the Closing an
acknowledged power of attorney to the foregoing effect.

counsel and accountants access to the books, records and other data relating to
the Assets in TARC's possession, if any, with respect to periods prior to the
Closing and the right to make copies and extracts therefrom. Further, TARC
agrees for a period extending six (6) years after the Closing Date not to
destroy or otherwise dispose of any books, records and other data without first
offering in writing to surrender such books, records and other data to TCR
Holding and TCR Holding shall not have agreed to take possession thereof within
thirty (30) days of such offer.

                  1.05 Third-Party Consents. To the extent that any Contract is
not assignable without the consent of another party, this Agreement shall not
constitute an assignment or an attempted assignment thereof if such assignment
or attempted assignment would constitute a breach of or a default under any
contract either constituting or governing Contract. TARC shall use its best
efforts to obtain the consent of such other party to the assignment of any
Contract in all cases in which such consent is or may be required for such
assignment. If any such consent shall not be obtained, TARC shall cooperate with
TCR Holding in any arrangement designed to provide TCR Holding with the benefits
intended to be assigned to TCR Holding under or pursuant to such Asset,
including enforcement at the cost and for the account of TARC of any and all
rights of TARC against the other party thereto arising out of the breach or
cancellation thereof by such other party or otherwise.

                  1.06 Agreed Value. The parties agree that for purposes of all
federal and state income tax filings the agreed upon value of the Assets will be
$1,100,000,000 as of October 31, 1998.

                  3.01 Indemnification.

                  (a) Each of TARC and TEC shall, jointly and severally, to the

                  3.02 Survival of Indemnity and Representations and Warranties.
The indemnity provisions contained in this Article III and the representations
and warranties of TARC and TEC contained in this Agreement (including those made
by reference to the Securities Purchase Agreement) shall survive indefinitely
regardless of (i) any investigation made at any time by or on behalf of any TCR
Party, (ii) any termination of this Agreement or the Securities Purchase
Agreement or (iii) acceptance of the Assets by TCR Holding.

                  3.03 General Indemnification Procedures. Any party claiming
entitlement to indemnification pursuant to Section 3.01 (the "Indemnified
Party"), shall give the party obligated to provide indemnification under Section
3.01 (the "Indemnifying Party") notice of any matter which an Indemnified Party
has determined has given or could give rise to a right of indemnification under
this Agreement, within 90 days of such determination, stating the amount of the
Loss, if known, and method of computation thereof, and containing a reference to
the provisions of this Agreement in respect of which such right of
indemnification is claimed or arises; provided, however, that the failure to
provide such notice shall not release the Indemnifying Party from any of its
obligations under this Article III, except to the extent the Indemnifying Party
is materially prejudiced by such failure, and shall not relieve the Indemnifying
Party from any other obligation or liability that it may have to any Indemnified
Party otherwise than under this Article III.

                  3.04 Indemnification of Third Party Claims.

                  (a) The obligations and Liabilities of an Indemnifying Party
under this Article III with respect to Losses arising from claims of any third
party which are subject to the indemnification provided for in this Article III
("Third Party Claims") shall be governed by and contingent upon the following
additional terms and conditions:

                  (1) If an Indemnified Party shall receive notice of any Third
                  Party Claim, the Indemnified Party shall give the Indemnifying
                  Party notice of such Third Party Claim within 30 days of the
                  receipt by the Indemnified Party of such notice; provided,
                  however, that the failure to provide such notice shall not
                  release the Indemnifying Party from any of its obligations
                  under this Article III, except to the extent the Indemnifying
                  Party is materially prejudiced by such failure, and shall not
                  relieve the Indemnifying Party from any other obligation or
                  liability that it may have to any Indemnified Party otherwise
                  than under this Article III.

                  (2) If the Indemnifying Party acknowledges in writing its
                  obligation to indemnify the Indemnified Party hereunder
                  against any Losses that may result from such Third Party
                  Claim, then the Indemnifying Party shall be entitled to assume
                  and control the defense of such Third Party Claim at its
                  expense and through counsel of its choice if it gives notice
                  of its intention to do so to the Indemnified Party; provided,
                  however, that if there exists or is reasonably likely to exist
                  a conflict of interest that would make it inappropriate for
                  the same counsel to represent both the Indemnified Party and
                  the Indemnifying Party, then the Indemnified Party shall be
                  entitled, upon obtaining the prior written approval of the
                  Indemnifying Party, to retain its own counsel, in each
                  jurisdiction for which 




                                       6
<PAGE>   10

                  the Indemnified Party determines counsel is required, at the
                  expense of the Indemnifying Party; provided further, that in
                  no event shall the Indemnifying Party be obligated to pay the
                  fees and expenses of more than one counsel for all Indemnified
                  Parties in each such jurisdiction.

                  (3) In the event the Indemnifying Party exercises the right to
                  undertake any such defense against any such Third Party Claim,
                  as provided above, the Indemnified Party shall cooperate with
                  the Indemnifying Party in such defense and make available to
                  the Indemnifying Party, without further cost or expense to the
                  Indemnifying Party, all witnesses, pertinent records,
                  materials and information in the Indemnified Party's
                  possession or under the Indemnified Party's control relating
                  thereto as is reasonably required by the Indemnifying Party.

                  (4) In the event the Indemnified Party is, directly or
                  indirectly, conducting the defense against any such Third
                  Party Claim, the Indemnifying Party shall cooperate with the
                  Indemnified Party in such defense and make available to the
                  Indemnified Party, without further cost or expense to the
                  Indemnified Party, all such witnesses, records, materials and
                  information in the Indemnifying Party's possession or under
                  the Indemnifying Party's control relating thereto as is
                  reasonably required by the Indemnified Party.

                  (5) No Third Party Claim may be settled without the prior
                  written consent of the Indemnifying Party, unless such
                  settlement (i) includes an unconditional release of both the
                  Indemnifying Party and each Indemnified Party from all
                  liability arising out of such Third Party claim and (ii) does
                  not include a statement as to or an admission of fault,
                  culpability or a failure to act by or on behalf of either the
                  Indemnifying Party or any Indemnified Party.

                  (6) The Indemnified Party agrees to repay to the Indemnifying
                  Party all amounts advanced to the Indemnified Party or
                  expended on Indemnified Party's behalf pursuant to this
                  Article III in the event that a court of competent
                  jurisdiction subsequently determines that the Indemnified
                  Party was not entitled to be indemnified pursuant to the terms
                  of this Article III.

                  (b) Subject to the foregoing conditions and obligations and
the conditions set forth below, TCR Holding has agreed to provide the TARC
Parties with limited indemnification with respect to the proceeding commenced by
the New Orleans District Office of the U.S. Equal Employment Opportunity
Commission ("EEOC"), which proceeding is captioned, "Commissioner Joyce E.

                  (1) TCR Holding shall, to the fullest extent permitted by
                  applicable law, indemnify and hold the TARC Parties harmless
                  against all judgments, fines and amounts paid in settlement,
                  to the extent actually and reasonably incurred by the TARC
                  Parties in connection with the EEOC Charge or any EEOC
                  Litigation (as 




                                       7
<PAGE>   11

                  such term is defined below), but excluding all expenses
                  (including reasonable attorneys' fees and disbursements)
                  incurred by the TARC Parties in connection therewith, to a
                  maximum amount of $1,000,000 (the "Indemnification Amount").

                  (2) TARC shall keep TCR Holding apprised of all activities
                  regarding the EEOC Charge, including, without limitation, all
                  communications from the EEOC, whether written or oral, any
                  attempt by the EEOC to engage in conciliation with respect to
                  the EEOC Charge and any actual or threatened court action
                  based on or arising out of the EEOC Charge (the "EEOC
                  Litigation");

                  (3) TCR Holding, at its option, shall be permitted to
                  participate in any activity relating to the EEOC Charge,
                  including any conciliation or other discussions with the EEOC,
                  and/or any EEOC Litigation and to assume the defense of
                  thereof, in whole or in part;

                  (4) TARC must cooperate fully in the defense of the EEOC
                  Charge and any EEOC Litigation; and

                  (5) TARC must refrain from settling or otherwise disposing of
                  the EEOC Charge and/or any EEOC Litigation, or having any
                  discussions in connection therewith, without obtaining TCR
                  Holding's prior written consent. In addition, TARC may not
                  enter into a settlement agreement with respect to the EEOC
                  Charge and/or any EEOC Litigation unless such settlement
                  agreement (i) includes an unconditional release of TCR
                  Holding, as a third party beneficiary, and (ii) does not
                  include a statement as to or any admission of fault,
                  culpability or a failure to act by or on behalf of either TARC
                  or TCR Holding.

                  (6) The Indemnification Amount shall be reduced by the

                  its successors or assigns, or John R. Stanley, or anyone
                  acting on his behalf, in connection with the action captioned

successors and assigns (collectively, the "TCR Parties") in respect of, and
hold TCR Holding harmless from and against, any and all Losses suffered,
incurred or sustained by any of them or to which any of them becomes subject,
resulting from, arising out of or relating to the Assets or the Assumed
Liabilities except to the extent that any such loss arises out of any Loss
giving rise to indemnification under Section 2.01(a).

                  2.02 Survival of Indemnity and Representations and Warranties.
The indemnity provisions contained in this Article II shall survive indefinitely
regardless of (i) any investigation made at any time by or on behalf of any
TransContinental Party, (ii) any termination of this Agreement or the Securities
Purchase Agreement or (iii) acceptance of the Assets by TransContinental.

                  2.03 Indemnification Procedures. An Indemnified Party shall
give the party obligated to provide indemnification under Section 2.01 (the
"Indemnified Party") notice of any matter which an Indemnified Party has
determined has given or could give rise to a right of indemnification under this
Agreement, within 90 days of such determination, stating the amount of the Loss,
if known, and method of computation thereof, and containing a reference to the
provisions of this Agreement in respect of which such right of indemnification
is claimed or arises; provided, however, that the failure to provide such notice
shall not release the Indemnifying Party from any of its obligations under this
Article II except to the extent the Indemnifying Party is materially prejudiced
by such failure and shall not relieve the Indemnifying Party from any other
obligation or liability that it may have to any Indemnified Party otherwise than
under this Article II. The obligations and Liabilities of an Indemnifying Party
under this Article II with respect to Losses arising from claims of any third
party which are subject to the indemnification provided for in this Article II
("Third Party Claims") shall be governed by and contingent upon the following
additional terms and conditions: if an Indemnified Party shall receive notice of
any Third Party Claim, the Indemnified Party shall give the Indemnifying Party
notice of such Third Party Claim within 30 days of the receipt by the
Indemnified Party of such notice; provided, however, that the failure to provide
such notice shall 

<PAGE>   7

not release the Indemnifying Party from any of its obligations under this
Article II except to the extent the Indemnifying Party is materially prejudiced
by such failure and shall not relieve the Indemnifying Party from any other
obligation or liability that it may have to any Indemnified Party otherwise than
under this Article II. If the Indemnifying Party acknowledges in writing its
obligation to indemnify the Indemnified Party hereunder against any Losses that
may result from such Third Party Claim, then the Indemnifying Party shall be
entitled to assume and control the defense of such Third Party Claim at its
expense and through counsel of its choice if it gives notice of its intention to
do so to the Indemnified Party; provided, however, that if there exists or is
reasonably likely to exist a conflict of interest that would make it
inappropriate in the judgment of the Indemnified Party, in its sole and absolute
discretion, for the same counsel to represent both the Indemnified Party and the
Indemnifying Party, then the Indemnified Party shall be entitled to retain its
own counsel, in each jurisdiction for which the Indemnified Party determines
counsel is required, at the expense of the Indemnifying Party; provided further,
that in no event shall the Indemnifying Party be obligated to pay the fees and
expenses of more than one independent counsel for all Indemnified Parties in
each such jurisdiction. In the event the Indemnifying Party exercises the right
to undertake any such defense against any such Third Party Claim as provided
above, the Indemnified Party shall cooperate with the Indemnifying Party in such
defense and make available to the Indemnifying Party, at the Indemnifying
Party's expense, all witnesses, pertinent records, materials and information in
the Indemnified Party's possession or under the Indemnified Party's control
relating thereto as is reasonably required by the Indemnifying Party. Similarly,
in the event the Indemnified Party is, directly or indirectly, conducting the
defense against any such Third Party Claim, the Indemnifying Party shall
cooperate with the Indemnified Party in such defense and make available to the
Indemnified Party, at the Indemnifying Party's expense, all such witnesses,
records, materials and information in the Indemnifying Party's possession or
under the Indemnifying Party's control relating thereto as is reasonably
required by the Indemnified Party. No such Third Party Claim may be settled
without the prior written consent of each Indemnified Party subject to such
Third Party Claim unless such settlement (i) includes an unconditional release
of both the Indemnifying Party and each Indemnified Party from all liability
arising out of such Third Party claim and (ii) does not include a statement as
to or an admission of fault, culpability or a failure to act by or on behalf of
either the Indemnifying Party or any Indemnified Party.
