                       TEXAS PETROCHEMICAL HOLDINGS, INC.
                               $57,650,103.55 OF
                      13.5% SENIOR DISCOUNT NOTES DUE 2007
           FULLY AND UNCONDITIONALLY GUARANTEED BY TPC HOLDING CORP.

     The 13.5% Senior Discount Notes due 2007 (the "Discount Notes") were
issued by Texas Petrochemical Holdings, Inc. ("Holdings" and together with its
subsidiaries on a consolidated basis, the "Company") pursuant to the Discount
Notes Indenture (as defined under "Description of the Discount
Notes -- General"). As of the date of this Prospectus, there are $57,650,103.55
aggregate principal amount at final maturity of the Discount Notes outstanding.
   
     The Discount Notes are unsecured senior Indebtedness of Holdings ranking
PARI PASSU with other unsecured senior Indebtedness of Holdings. Holdings
conducts its operations through its subsidiaries and as a result is dependent
upon the transfer of funds by its subsidiaries to make payment on the Discount
Notes. The Discount Notes are guaranteed by Holdings' subsidiary, TPC Holding
Corp. ("TPC Holding"), which as a holding company is also dependent upon the
transfer of funds by its subsidiaries to make payment on the Discount Notes as
guarantor. The Discount Notes and TPC Holding's guarantee are effectively
subordinated to secured indebtedness of Holdings, including Holdings' guaranty
of the Indebtedness of its subsidiary, Texas Petrochemicals Corporation
("TPC"), under the Bank Credit Agreement (as defined under "Description of
the Bank Credit Agreement"), and to all indebtedness and other liabilities of
TPC and its subsidiaries. As of March 3, 1998, the aggregate amount of senior
Indebtedness of Holdings (other than the Discount Notes) was $96.0 million,
consisting of Holdings' guaranty of TPC's Indebtedness under the Bank Credit
Agreement, and the aggregate amount of Indebtedness and other obligations of
Holdings and its subsidiaries was approximately $363.3 million. Because the
Discount Notes do not accrue cash interest prior to July 1, 2001, the Discount
Notes are not suitable investments for investors seeking current income.
    
     The initial issue amount of each Discount Note was $520.38 per $1,000
principal amount at maturity (52% of the principal amount at maturity),
representing a yield to maturity of 13.5% (computed on a semi-annual bond
equivalent basis) calculated from July 1, 1996. Cash interest will not accrue on
the Discount Notes prior to July 1, 2001, at which time cash interest will
accrue on the Discount Notes at a rate of 13.5% PER ANNUM. Interest on the
Discount Notes is payable semi-annually on January 1 and July 1 of each year,
commencing January 1, 2002. Except as described below, the Discount Notes are
not redeemable at the option of Holdings prior to July 1, 2001. Thereafter, the
Discount Notes will be redeemable, in whole or in part, at the option of
Holdings, at the redemption prices set forth herein together with accrued and
unpaid interest, if any, to the date of redemption. In addition, up to 30% of
the aggregate Accreted Value (as defined under "Description of the Discount
Notes -- Certain Definitions") of the Discount Notes may be redeemed at any
time prior to July 1, 1998, at the option of Holdings, from the net proceeds of
any Public Equity Offering following which there is a Public Market (as such
terms are defined under "Description of the Discount Notes -- Certain
Definitions") at a redemption price equal to 113.5% of the Accreted Value
thereof, together with accrued and unpaid interest, if any, to the redemption
date. Upon the occurrence of a Change of Control (as defined under "Description
of the Discount Notes -- Certain Definitions"), each holder of Discount Notes
may require Holdings to purchase all or a portion of such holder's Discount
Notes at a purchase price in cash equal to 101% of the principal amount thereof,
together with accrued and unpaid interest, if any, to the date of purchase. For
a more complete description of the Discount Notes, see "Description of the
Discount Notes."
     This Prospectus is being used by The Huff Alternative Income Fund, L.P.
(the "Huff Fund") in connection with offers and sales of the Discount Notes in
the over-the-counter market, in private transactions, or otherwise at negotiated
prices related to prevailing market prices at the time of sale. The Company will
not receive any proceeds from the sale of the Discount Notes by the Huff Fund.
See "Plan of Distribution."
     Promptly following the Company's filing of quarterly reports or other

                                  THE COMPANY

     The Company is the largest producer of butadiene and butene-1, and the
third largest producer of methyl tertiary-butyl ether ("MTBE"), in North
America, in terms of production capacity. In addition, the Company is the sole
producer of diisobutylene and isobutylene concentrate in the United States and
the largest domestic merchant supplier of high purity isobutylene to the
chemical market. The Company's products include: (i) butadiene, primarily used
to produce synthetic rubber; (ii) MTBE, used as an oxygenate and octane enhancer
in gasoline; (iii) n-butylenes (butene-1 and butene-2), used in the manufacture
of plastic resins, fuel additives and synthetic alcohols; and (iv) specialty
isobutylenes, primarily used in the production of specialty rubbers, lubricant
additives, detergents and coatings. For the year ended June 30, 1997, and the
twelve months ended May 31, 1996, butadiene represented 27% and 25% of the
Company's total revenues, respectively, MTBE represented 47% and 41%,
respectively, n-butylenes 10% and 11%, respectively, specialty isobutylenes 13%
and 16%, respectively, and other revenues the remaining 3% and 7%, respectively.
The Company's revenues for the year ended June 30, 1997, the twelve months ended
May 31, 1996 and the one month ended June 30, 1996 were $490.2 million, $455.6
million and $41.4 million, respectively, and EBITDA (as defined) for the year
ended June 30, 1997, the twelve months ended May 31, 1996 and the one month
ended June 30, 1996 were $50.4 million, $57.0 million and $3.7 million,
respectively.

     Butadiene is the most widely used feedstock for synthetic rubber products
and is also used in the manufacture of engineered plastics, nylon fibers and
other products. The Company sells butadiene to a stable customer base ,
including The Goodyear Tire & Rubber Company, The Dow Chemical Company, American
Synthetic Rubber Inc. and Bridgestone/Firestone, Inc. As the largest producer of
butadiene in North America, the Company believes that many of its customers
place significant value on its ability to provide a reliable domestic supply of
butadiene and as a result have entered into long-term sales contracts with the
Company.

     The Company extracts butadiene from crude butadiene, which is generated
from the production of ethylene and is comprised of a number of valuable
components, including butadiene, isobutylene, n-butylenes, isobutane and
n-butane. Many U.S. ethylene producers rely on third parties such as the

                                       3
<PAGE>
Company to process their crude butadiene streams, as the crude butadiene volumes
they produce are not sufficient to justify the construction of on-site butadiene
recovery facilities. The Company estimates that producers accounting for 65% of
U.S. and Canadian ethylene production capacity do not internally process crude
butadiene by-product streams. The Company is the largest non-integrated crude
butadiene processorin North America and as a result of its strategic importance
to ethylene producers, the Company has been able to secure long-term supply
contracts covering the majority of its crude butadiene requirements. Such
contracts provide for a fixed profit based on the Company's selling prices for
butadiene, and account for the relatively stable profitability of the Company's
butadiene operations.

     MTBE is a blending stock which reduces carbon monoxide and volatile organic
compound emissions and enhances the octane content of gasoline, and has been one
of the fastest growing petrochemicals, in terms of volume, over the past fifteen
years. Today, MTBE is the preferred oxygenate for, and a major component of,
reformulated gasoline ("RFG") and is used in over 30% of the U.S. gasoline
pool. MTBE is produced by reacting methanol and isobutylene, and the Company's
ability to produce isobutylene by three alternative methods enables it to
produce MTBE by the most economical processes available to the Company. In
addition, the Company has the ability to add incremental capacity to capitalize
on expected future growth, at a significantly lower cost than the cost of adding
new capacity. The Company believes that this incremental capacity gives it a
competitive advantage over other producers who would have to incur greater cost
to increase capacity. The Company sells MTBE to oil refiners and gasoline
producers, including Mobil Oil Corporation, Lyondell Petrochemical Company and
CITGO Petroleum Corporation on both a contract and spot basis at prices linked
to prevailing market prices.

     The Company is the leading producer of high margin n-butylenes and
specialty isobutylenes in North America. In recent years, the Company has
increased its sales of these products by increasing its market share in
polyolefin applications and the development of new end-use applications. The
Company's principal customers for n-butylenes include Union Carbide Corporation,
The Dow Chemical Company, NOVA Chemicals Ltd., Shell Chemical Company and
Lyondell Petrochemical Company. The Company's principal customers for specialty
isobutylenes include Bayer Inc., Mobil Chemical Company Inc., Rhone-Poulenc
Inc., The Lubrizol Corporation and Schenectady International, Inc. Historically,
the profitability of the Company's n-butylenes sales has been relatively stable
as the majority of the sales of these products are made under contracts which
link their selling prices to the prices of products (principally gasoline and
butanes) whose prices fluctuate closely with those of the raw materials used to
manufacture n-butylenes and specialty isobutylenes.

     The Company's principal feedstocks are crude butadiene, isobutane and
methanol. One of the Company's intermediate feedstocks, isobutylene, is used in
the manufacture of MTBE and specialty isobutylenes. As part of its production
strategy, the Company uses its manufactured isobutylene first to maximize the
production of high margin specialty isobutylenes, second, to satisfy its
contractual MTBE requirements, and finally to produce MTBE for sale in the spot
market. The Company maintains the production flexibility to upgrade n-butylenes
contained in crude butadiene streams to either isobutylene or butene-1 using its
patented skeletal isomerization process ("SKIP"). This flexibility allows the
Company to meet its customers' needs through the most economical process, to
produce additional products and to capitalize on favorable market conditions.

     The Company's manufacturing facility, located approximately one mile from
the Houston Ship Channel, provides convenient access to other Gulf Coast
petrochemical producers and is connected to several of its customers and raw
materials suppliers through an extensive pipeline network. In addition, the
Company's facility is serviced by rail, tank truck and barge.

     The Company's principal executive offices are located at Three Riverway,
Suite 1500, Houston, Texas 77056. The Company's telephone number is (713)
627-7474.

                             BACKGROUND INFORMATION

     Holdings, TPC Holding, and TPC Finance Corp., a Texas corporation ("Finance
Co."), were organized in May 1996 to effect the acquisition (the "Acquisition")
of TOC and its subsidiaries, including TPC, and to assume a raw materials supply
contract from Clarkston. On July 1, 1996, Holdings issued and sold $43.8 million
of its common stock ("Common Stock") to an investor group led by Gordon A. Cain
and The Sterling Group, Inc. ("Sterling"), issued $6.2 million of its Common
Stock for the shares contributed by certain shareholders of TOC and TPC, sold a
sufficient amount of the Discount Notes and Common Stock, as an investment unit
(the "Units") to the Huff Fund to raise $30 million in gross proceeds, and
contributed the net proceeds thereof to TPC Holding. Finance Co. borrowed
approximately $140.0 million under the Bank Credit Agreement and received
approximately $169 million in net proceeds from the sale at such time of $175
million aggregate principal amount of 11 1/8% Senior Subordinated Notes due 2006
(the "Original Notes") and loaned the combined net proceeds to TPC Holding. TPC
Holding used the capital contributions received from Holdings, cash on hand and
the proceeds of the loan from Finance Co. to effect the Acquisition pursuant to
a stock purchase agreement dated as of May 14, 1996 (the "Stock Purchase
Agreement"), to fund the ESOP (as defined) and pay fees and expenses in
connection with the transactions associated with the Acquisition. TOC and
Finance Co. then merged into TPC.

     As a result of the foregoing, Holdings is the primary obligor on the
Discount Notes, and TPC is the primary obligor on the Original Notes and the
loans made pursuant to the Bank Credit Agreement, is a wholly-owned subsidiary
of TPC Holding (which in turn is wholly-owned by Holdings) and operates the
principal business of the Company. Holdings has guaranteed TPC's obligations
under the Bank Credit Agreement. The Discount Notes and the Common Stock which
constituted the Units became separately transferable immediately following the
Acquisition.

     On March 13, 1997, TPC issued and sold $50,000,000 aggregate principal
amount of 11 1/8% Series B Senior Subordinated Notes due 2006 (the "Notes"),
the proceeds of which were used to, among other things, reduce TPC's
indebtedness under the Bank Credit Agreement. The Original Notes and the Notes
were issued under indentures referred to herein collectively as the "Notes
Indenture."

     This prospectus has been prepared for use by the Huff Fund in connection
with offers and sales of the Discount Notes.

                                       of purchase. See "Description of the Discount Notes -- Change of
                                       Control."
Ranking..............................  The Discount Notes are senior unsecured obligations of Holdings, senior
                                       in right of payment to subordinated Indebtedness of Holdings, including
                                       Holdings' guarantee of the Notes. The Discount Notes rank PARI PASSU in
                                       right of payment with other senior unsecured Indebtedness of Holdings.
                                       The Discount Notes are effectively subordinated to secured indebtedness
                                       of Holdings, including Holdings' guarantee of Indebtedness of TPC under
                                       the Bank Credit Agreement, as to the assets of Holdings securing such
                                       Indebtedness, and to all Indebtedness and other liabilities and
                                       commitments (including trade payables and lease obligations) of
                                       Holdings' subsidiaries. As of March 3, 1998, (i) Holdings had
                                       approximately $96.0 million of secured senior Indebtedness outstanding
                                       (consisting of Holdings' guarantee of the Company's Indebtedness under
                                       the Bank Credit Agreement), $37.0 million of senior unsecured
                                       Indebtedness outstanding (consisting of the portion of the issue price
                                       of the Units allocated for accounting purposes to the Discount Notes)
                                       and (ii) Holdings' subsidiaries had approximately $326.3 million of
                                       Indebtedness outstanding (including the Notes). Substantially all of the
                                       operations of Holdings will be conducted through its subsidiaries and,
                                       therefore, Holdings will be dependent upon the cash flow of its
                                       subsidiaries to meet its obligations, including its obligations under
                                       the Discount Notes. See "Description of the Discount Notes."
Restrictive Covenants................  The Discount Notes Indenture (as defined under "Description of the
                                       Discount Notes -- General") contains certain covenants that, among
                                       other things, limit the ability of Holdings and/or its Restricted
                                       Subsidiaries (as defined) to (i) incur additional indebtedness, (ii) pay
                                       dividends or make certain other restricted payments, (iii) make
                                       investments, (iv) enter into transactions with affiliates, (v) make
                                       certain asset dispositions, and (vi) merge or consolidate with, or
                                       transfer substantially all of its assets to, another person. The
                                       Discount Notes Indenture also limits the ability of Holdings' Re-
                                       stricted Subsidiaries to issue Capital Stock (as defined) and to create
                                       restrictions on the ability of such Restricted Subsidiaries to pay
                                       dividends or make any other distributions. In addition, Holdings is
                                       obligated, under certain circumstances, to offer to repurchase the

<PAGE>
                                       Discount Notes at a purchase price equal to 100% of their Accreted Value
                                       (without premium), plus accrued and unpaid interest, if any, in
                                       accordance with the procedures set forth in the Discount Notes
                                       Indenture. However, all of these limitations and prohibitions will be
                                       subject to a number of important qualifications. See "Description of
                                       the Discount Notes -- Certain Covenants."
Tax Consequences.....................  Holdings has received an opinion of counsel regarding the material
                                       federal income tax consequences relevant to the purchase, ownership and
                                       disposition of the Discount Notes. See "Material Federal Income Tax
                                       Considerations."
Guarantee............................  TPC Holding fully and unconditionally guarantees the due and punctual
                                       payment of the principal of, interest on and all other amounts payable
                                       under the Discount Notes when they become due and payable, whether upon
                                       maturity, upon acceleration, by call for redemption, upon repurchase or
                                       purchase pursuant to a Change of Control or Asset Disposition or
                                       otherwise. The guarantee will not be discharged with respect to any
                                       Discount Note except by payment in full of principal, interest and all
                                       other amounts payable.
</TABLE>
    
                              RECENT DEVELOPMENTS
   
     Holdings requested and obtained from the current holder of the entire
principal amount of the Discount Notes a waiver, for a single transaction, of
the requirements under Section 10.09(a)(ii) and (iii) of the Discount Notes
Indenture to the extent such requirements would not be met by the investment by
a Restricted Subsidiary of Holdings of up to $1,000 for a 50% interest in a
corporation organized to conduct certain business in Venezuela. Section 10.09 of
the Discount Notes Indenture states that the Company shall not permit any
Restricted Subsidiary to make a Restricted Payment unless certain tests are met.
The proposed investment of up to $1,000 in a corporation organized to conduct
certain business in Venezuela would constitute a Restricted Payment and as a
result the tests under Section 10.09 must be met or an exemption must be
available. Because the Company could not meet the tests under Section 10.09 and
an exemption was not available, the Company sought and obtained a waiver of
Section 10.09(a)(ii) and (iii) of the Discount Notes Indenture. See
"Description of the Discount Notes -- Certain Covenants -- Limitation on
Restricted Payments" and "Description of the Discount Notes -- Certain
Definitions -- Restricted Payment."

(1) The Company classifies variable compensation paid to employees as cost of
    goods sold. Previously, the Company had classified this cost as selling,
    general and administrative expenses. The Company has made reclassifications
    to the prior periods in order to conform to the current period presentation.

(2) Includes dividend income, charitable contributions, gain (loss) on disposal
    of assets and investment securities, net, and other, net. For the twelve
    months ended May 31, 1996, other expense includes an impairment of
    investment in land of $12.6 million.

(3) Approximately 95% of the Company's butadiene sales are under fixed profit
    contracts with suppliers of crude butadiene.

(4) Includes Clarkston's trading revenues from third parties (for the periods
    prior to July 1, 1996), utility revenues, revenues realized from the
    Company's terminalling facilities and sales of chemical by-products.

(5) Volumes in millions of gallons.

(6) EBITDA represents income before income taxes, extraordinary loss and
    minority interest before taking into consideration interest expense,
    depreciation and amortization and certain other non-recurring charges.
    EBITDA is presented because it is a widely accepted financial indicator of a
    company's ability to incur and service debt. EBITDA should not be construed
    by an investor as an alternative to income from operations (as determined in
    accordance with generally accepted accounting principles), as an indicator
    of the operating performance of the Company or as an alternative to cash
    flows from operating activities (as determined in accordance with generally
    accepted accounting principles) as a measure of liquidity.

                                  RISK FACTORS

     IN ADDITION TO THE OTHER INFORMATION IN THIS PROSPECTUS, PURCHASERS OF THE
DISCOUNT NOTES OFFERED HEREBY SHOULD CONSIDER CAREFULLY THE RISK FACTORS SET
FORTH BELOW.

DEPENDENCE ON SUBSIDIARY CASH FLOW

     Holdings, through TPC Holding, owns all the outstanding common stock of
TPC. As a holding company without significant assets other than its indirect
ownership of all of the common stock of TPC, Holdings' ability to meet its cash
obligations, including debt service on the Discount Notes, is dependent upon the
cash flow of its subsidiaries and the transfer of funds by its subsidiaries in
the form of loans, dividends or otherwise. In addition, the Bank Credit
Agreement and the Notes Indenture contain limitations on the ability of such
subsidiaries to pay dividends or make loans or advances to Holdings. Similarly,
TPC Holding, guarantor of the Discount Notes, has no independent operations and
is dependent upon distributions from TPC. As a result, TPC Holding, as guarantor
of the Discount Notes, may not be able to make timely or sufficient payment upon
the Discount Notes.

EFFECTIVE SUBORDINATION

     Because Holdings is a holding company that conducts its business through
its subsidiaries, the Discount Notes will be effectively subordinated to all
existing and future liabilities of Holdings' subsidiaries, including trade
payables. Likewise, TPC Holding is a holding company and the guarantee will be
effectively subordinated to all existing and future liabilities of TPC Holding's
subsidiaries, including trade payables. The Discount Notes Indenture limits, but
does not prohibit, the incurrence of additional indebtedness by Holdings and
certain of its subsidiaries. See "Description of the Discount Notes -- Certain
Covenants."

     The Discount Notes will not be secured by any of Holdings' assets. Holdings
pledged all of the capital stock of the TPC Holding and TPC to secure borrowings
of TPC under the Bank Credit Agreement. If TPC becomes insolvent or is
liquidated, or if payment under the Bank Credit Agreement is accelerated, the
lenders under the Bank Credit Agreement would be entitled to exercise the
remedies available to a secured lender under applicable law and pursuant to the
Bank Credit Agreement. Accordingly, such lenders will have a prior claim on the
assets of Holdings.

SUBSTANTIAL LEVERAGE
   
     The Company has incurred a significant amount of indebtedness and has
significant debt service requirements. As of December 31, 1997, the Company had
outstanding indebtedness of $344.2 million and the Company's stockholders'
equity was $24.1 million. See "Capitalization" and "Selected Financial
Data." In addition, the Company may incur additional indebtedness in the
future, subject to limitations imposed by its debt instruments including,
without limitation, the Discount Notes Indenture and the Bank Credit Agreement.
TPC is the primary obligor under the Bank Credit Agreement. Holdings has
guaranteed TPC's obligations under the Bank Credit Agreement. TPC also has
additional borrowing capacity on a revolving credit basis under the Bank Credit
Agreement.
    
     The Company's high degree of leverage could have important consequences to
the holders of the Discount Notes, including but not limited to the following:
(i) the Company's ability to obtain additional financing for working capital,
capital expenditures, acquisitions, debt service requirements, general corporate
purposes or other purposes may be impaired in the future; (ii) a substantial
portion of the Company's cash flow from operations must be dedicated to the
payment of principal and interest on its indebtedness, thereby reducing the
funds available to the Company for other purposes, including its operations and
future business opportunities; (iii) certain of TPC's borrowings, including
certain borrowings under the Bank Credit Agreement, are at variable rates of
interest, which expose the Company to the risk of increased interest rates; (iv)
the indebtedness outstanding under the Bank Credit Agreement is secured by
substantially all the assets of the Company and will mature prior to the
maturity of the Discount Notes; and (v) the Company's flexibility to adjust to
changing market conditions and ability to withstand competitive pressures could
be limited by its leveraged position and the covenants contained in its debt
instruments, thus

                                       10
<PAGE>
putting the Company at a competitive disadvantage, and the Company may be more
vulnerable to a downturn in general economic conditions or in its business or be
unable to carry out capital spending that is important to its growth and
productivity improvement programs. See "Description of the Bank Credit
Agreement" and "Description of the Discount Notes."

     The Company began making scheduled principal payments under the Bank Credit
Agreement commencing on September 30, 1996. See "Description of the Bank Credit
Agreement." The Company's ability to make scheduled payments or to refinance
its obligations with respect to its indebtedness, including the Discount Notes,
will depend on its financial and operating performance, which is subject to
prevailing economic and competitive conditions and to certain financial,
business and other factors beyond its control, including interest rates,
unscheduled plant shutdowns, increased operating costs, raw material and product
prices, and regulatory developments. There can be no assurance that TPC will
maintain a level of cash flow from operations sufficient to permit it to make
payments or dividends to Holdings in order for Holdings to pay the scheduled
payments of interest on the Discount Notes.

     If the Company's cash flow and capital resources are insufficient to fund
its debt service obligations, the Company may be forced to reduce or delay
capital expenditures, sell assets, or seek to obtain additional equity capital
or restructure or refinance its debt (including the Discount Notes). There can
be no assurance that such alternative measures would be successful or would
permit the Company to meet its scheduled debt service obligations. In the
absence of such operating results and resources, the Company could face
substantial liquidity problems and might be required to dispose of material
assets or operations to meet its debt service and other obligations. The Bank
Credit Agreement, the Discount Notes Indenture and the Notes Indenture restrict
the Company's ability to sell assets and use the proceeds therefrom. See
"Description of the Bank Credit Agreement" and "Description of the Discount
Notes." There can be no assurance as to the ability of the Company to
consummate such sales or the proceeds which the Company could realize therefrom
or that such proceeds would be adequate to meet the obligations then due.

     In the event that the Company is unable to generate sufficient cash flow
and the Company is otherwise unable to obtain funds necessary to meet required
payments of principal, premium, if any, and interest on its indebtedness, or if
the Company otherwise fails to comply with the various covenants in the
instruments governing such indebtedness, the Company could be in default under
the terms of the agreements governing such indebtedness, including, without
limitation, each of the Discount Notes Indenture and the Bank Credit Agreement.
In the event of such default, the holders of such indebtedness could elect to
declare all of the funds borrowed thereunder to be due and payable together with
accrued and unpaid interest, the lenders under the Bank Credit Agreement could
elect to terminate their commitments thereunder and the Company could be forced
into bankruptcy or liquidation. Any default under the agreements governing the
indebtedness of the Company could have a significant adverse effect on the
Company's ability to pay principal, premium, if any, and interest on the
Discount Notes and on the market value of the Discount Notes. See "Description
of the Discount Notes" and "Description of the Bank Credit Agreement."

RESTRICTIVE FINANCING COVENANTS AND CROSS-DEFAULT RISKS

     The Bank Credit Agreement contains a number of significant covenants that,
among other things, restricts the ability of the Company to dispose of assets or
merge, incur additional indebtedness, incur guarantee obligations, repay certain
outstanding indebtedness or amend the Discount Notes Indenture or the Notes
Indenture, pay dividends, create liens on assets, enter into sale and leaseback
transactions, make investments, loans or advances, make acquisitions, engage in
mergers or consolidations, make capital expenditures or engage in certain
transactions with affiliates, and otherwise restrict corporate activities. The
Bank Credit Agreement allows, however, TPC to make payments or dividends to
Holdings commencing fiscal year 2002 to be used by Holdings solely for scheduled
payments of interest on the Discount Notes. In addition, under the Bank Credit
Agreement, the Company is required to comply with specified financial ratios and
tests, including a limitation on capital expenditures, an EBITDA to fixed
charges ratio, a minimum net worth test, a total debt to EBITDA ratio, and a
current ratio. The Company received waivers of compliance with its total debt to
EBITDA ratio as of December 31, 1996, March 31, 1997 and June 30, 1997. The
Company also obtained amendments to the Bank Credit Agreement as of March 31,
1997 and

                                       11
<PAGE>
June 30, 1997 to update these financial ratios. See "Description of the Bank
Credit Agreement." The Discount Notes Indenture also contains a number of
restrictive covenants. See "Description of the Discount Notes -- Certain
Covenants."

     The Company's ability to comply with the covenants and restrictions
contained in the Bank Credit Agreement, the Discount Notes Indenture, or the
Notes Indenture may be affected by events beyond its control, including
prevailing economic, financial and industry conditions. The breach of any such
covenants or restrictions could result in a default under the Bank Credit
Agreement, the Discount Notes Indenture, or the Notes Indenture, which would
permit the lenders under the Bank Credit Agreement or the holders of Original
Notes, Notes or the Discount Notes, as the case may be, to declare all amounts
outstanding thereunder to be due and payable, together with accrued and unpaid
interest, and the commitments of the lenders under the Bank Credit Agreement to
make further extensions of credit could be terminated. In addition, in the event
of a default under the Bank Credit Agreement, in certain circumstances the
lenders under the Bank Credit Agreement could elect to prevent the Company from
making any payments on the Discount Notes. See "Description of the Discount
Notes -- Ranking." If the Company were unable to repay its indebtedness to the
lenders under the Bank Credit Agreement, such lenders could proceed against the
collateral securing such indebtedness as described under "Description of the
Bank Credit Agreement." There can be no assurance that in the event of any such
default the Company will have adequate resources to repay in full principal,
premium, if any, and interest on the Discount Notes.

CHANGE OF CONTROL

     Upon the occurrence of a Change of Control (as defined under "Description
of the Discount Notes -- Certain Definitions"), the Company is required to
offer to purchase all of the outstanding Discount Notes at a price equal to 101%
of the principal amount thereof at the date of purchase plus accrued and unpaid
interest, if any, to the date of purchase. The occurrence of certain of the
events which would constitute a Change of Control constitutes a default under
the Bank Credit Agreement. In addition, the Bank Credit Agreement prohibits the
purchase of the Discount Notes by the Company in the event of a Change of
Control, unless and until such time as the indebtedness under the Bank Credit
Agreement is repaid in full. The Company's failure to purchase the Discount
Notes in such instance would result in a default under the Discount Notes
Indenture and the Bank Credit Agreement. The inability to repay the indebtedness
under the Bank Credit Agreement, if accelerated, would also constitute an event
of default under the Discount Notes Indenture, which could have materially
adverse consequences to the Company and to the holders of the Discount Notes. In
the event of a Change of Control, there can be no assurance that the Company
would have sufficient assets to satisfy all of its obligations under the Bank
Credit Agreement and the Discount Notes. See "Description of the Discount
Notes -- Change of Control" and "Description of the Bank Credit Agreement."

CYCLICAL INDUSTRIES

     The Company's primary business consists of the production of butadiene,
MTBE, n-butylenes and specialty isobutylenes. The prices of certain of these
products have historically been cyclical and have been sensitive to overall
production capacity relative to demand, the availability and price of feedstocks
and the level of general business activity. In the past, certain of these
products have experienced market shortages, accompanied by relatively high
prices, and periods of oversupply, accompanied by relatively low prices.

     While the Company has achieved relatively stable profitability on its sales
of butadiene due to the nature of the supply contracts under which it purchases
crude butadiene, industry profitability for MTBE has fluctuated considerably
over the past several years. In the early 1990s, considerable additional
production capacity was installed in the U.S. in anticipation of demand for MTBE
created by the Federal Clean Air Act Amendments of 1990 ("CAAA"). This demand
did not completely materialize due to states opting-out of the programs
promulgated by the CAAA as well as less than anticipated demand in states not
required to comply with such programs, resulting in an industry overcapacity
condition that has resulted in lower average selling prices and margins.

                                       12
<PAGE>
HIGHLY COMPETITIVE INDUSTRY

     The petrochemical businesses in which the Company operates are highly
competitive. Many of the Company's competitors are larger and have greater
financial resources than the Company. Among the Company's competitors are some
of the world's largest chemical companies and major integrated petroleum
companies that have their own raw material resources. In addition, a significant
portion of the Company's business is based upon widely available technology.
Accordingly, barriers to entry, apart from capital availability, may be low in
the commodity product section of the Company's business, and the entrance of new
competitors into the industry may reduce the Company's ability to capture
improving profit margins in circumstances where overcapacity in the industry is
diminishing. Furthermore, petroleum-rich countries have recently become more
significant participants in the petrochemical industry and may expand such role
significantly in the future. Any of these developments could have a negative
impact on the Company's financial position, results of operations and cash
flows. See "Business -- Competition."

DEPENDENCE ON KEY CUSTOMERS

     Certain of the Company's largest customers account for a significant
percentage of the Company's sales. In the year ended June 30, 1997 approximately
41% of the Company's sales were made to four customers. In addition, in the year
ended June 30, 1997 approximately 16.7% of the Company's total revenues were
derived from a single customer and 11.4% of the Company's total revenues were
derived from an additional single customer. Although the Company believes its
relationships with its largest customers are good, the loss of a significant
customer or a number of significant customers would have a material adverse
effect on the Company's financial condition, results of operations and cash
flows. There can be no assurance that the historic levels of business from these
customers or the Company's ability to replace a lost customer will be maintained
in the future.

ENVIRONMENTAL REGULATION

     The Company's operations are subject to extensive Federal, state and local
laws, regulations and decrees governing, among other things, emissions to air,
discharges to waters and the generation, handling, storage, transportation,
treatment and disposal of waste materials. The Company's production facilities
require operating permits that are subject to revocation, modification and
renewal, violations of which may provide for substantial fines and civil or
criminal sanctions. The operation of any chemical manufacturing plant entails
risk of adverse environmental effect, including exposure to chemical products
and by-products from the Company's operations, and there can be no assurance
that material costs or liabilities will not be incurred to rectify any such
damage. In addition, potentially significant expenditures could be required in
order to comply with environmental, health and safety laws and regulations that
may be adopted or imposed in the future. To meet changing licensing and
regulatory standards, the Company may be required to make additional significant
site or operational modifications, potentially involving substantial
expenditures or the reduction or suspension of certain operations. See
"-- Dependence on Single Facility" and "Business -- Environmental
Regulation."

PRICE VOLATILITY OF PETROCHEMICAL FEEDSTOCKS

     The Company uses large amounts of petrochemical feedstocks in the
manufacturing of its chemical products. While the Company tries to match cost
increases with corresponding price increases, there may be periods of time
during which increases in feedstock prices are not recovered by the Company due
to an inability to increase the selling prices of its products because of
weakness in demand for, or oversupply of, such products.

     The principal raw material feedstocks purchased by the Company are crude
butadiene, isobutane and methanol. A number of the Company's raw material
suppliers provide the Company with a significant amount of its raw materials,
and if one significant supplier or a number of significant suppliers were unable
to meet their obligations under present supply arrangements, or if such
arrangements could not be renewed upon expiration, the Company could be required
to incur increased costs for its raw materials. The ability to pass on increases
in raw material prices to the Company's customers is, to a large extent,
dependent on

                                       13
<PAGE>
market conditions. There may be periods of time in which increases in feedstock
prices are not recovered by the Company due to an inability to increase the
selling prices of its products because of weakness in demand for, or oversupply
of, such products, and therefore, certain increases in raw materials prices may
have a material adverse effect on the operations of the Company.

DEPENDENCE ON SINGLE FACILITY; LIMITED INSURANCE COVERAGE

     The Company has one major operating facility located approximately one mile
from the Houston Ship Channel. The loss or shutdown of operations over an
extended period of time at such facility would have a material adverse effect on
the Company. The Company's operations are subject to the usual hazards
associated with chemical manufacturing and the related storage and
transportation of feedstocks, products and wastes, including explosions, fires,
inclement weather and natural disasters, mechanical failure, unscheduled
downtime, transportation interruptions, chemical spills, discharges or releases
of toxic or hazardous substances or gases and other environmental risks, such as
required remediation of contamination. These hazards can cause personal injury
and loss of life, severe damage to or destruction of property and equipment and
environmental damage, and may result in suspension of operations and the
imposition of civil or criminal penalties. The Company maintains property,
business interruption and casualty insurance at levels which it believes are in
accordance with customary industry practice, but there can be no assurance that
the Company will not incur losses beyond the limits or outside the coverage of
its insurance.

FACTORS AFFECTING DEMAND FOR MTBE

     One of the Company's core products is MTBE, an oxygenate and octane
enhancer used in reformulated gasoline. The CAAA mandates numerous comprehensive
specifications for motor vehicle fuel, including minimum oxygen content and
reduced emissions of ozone precursors. Future demand for MTBE will depend on,
among other things, the degree to which the CAAA is implemented and enforced,
the possible adoption of additional legislation, the degree to which existing
ozone non-attainment areas come into compliance with air quality standards, the
degree to which gasoline suppliers can isolate ozone non-attainment areas where
the use of oxygenates is not required and the results of ongoing and any future
scientific studies regarding the health effects of oxygenates added to gasoline.
In addition, although the Company expects that there will be a continued market
preference and governmental support for MTBE, it is possible that alternative
oxygenates or octane enhancers could make inroads into MTBE's market share.
Recently there have been legislative initiatives to eliminate the use of MTBE as
a fuel additive in certain geographic areas. To date such initiatives have not
been successful. The Company cannot predict whether such legislation will be
reintroduced, or if it would be enacted if reintroduced; however, the
elimination of MTBE as a fuel additive in major markets could have a material
adverse effect on the Company. See "Business -- Industry Overview -- MTBE" and
"Business -- Environmental Regulation."

REGULATION OF EXPOSURE TO BUTADIENE

     Butadiene is a known carcinogen in laboratory animals at high doses and is
being studied for its potential adverse health effects. Effective February 1997,
the Occupational Safety and Health Administration lowered substantially the
employee permissible exposure limit for butadiene. Although the Company believes
that it is in compliance with the new regulatory limit and may maintain
compliance without incurring significant costs, there can be no assurance that
future scientific studies regarding the health effects of butadiene or any other
product handled by the Company will not result in more stringent regulations or
in restrictions on the use of, or exposure to, such products. See
"Business -- Environmental Regulation."

ORIGINAL ISSUE DISCOUNT OF DISCOUNT NOTES

     The Discount Notes were issued at a substantial discount from their
principal amount at final maturity. Consequently, although cash interest will
not accrue on the Discount Notes prior to July 1, 2001, and there will be no
periodic payments of cash interest on the Discount Notes prior to January 1,
2002, original issue discount will be included as interest on an accrual basis
in the gross income of a holder of Discount Notes, for federal income tax
purposes, in advance of the receipt of cash payments on the Discount Notes. See

                                       14
<PAGE>
"Material Federal Income Tax Considerations" for a more detailed discussion of
the federal income tax consequences to the holders of the Discount Notes
regarding the purchase, ownership and disposition of the Discount Notes.

     If a bankruptcy case is commenced by or against Holdings under the United
States Bankruptcy Code after the issuance of the Discount Notes, the claim of a
holder of Discount Notes with respect to the principal amount thereof may be
limited to an amount equal to the sum of (i) the portion of the initial issue
price of the Units allocated, for federal income tax purposes, to the Discount
Notes and (ii) that portion of the original issue discount which is not deemed
to constitute "unmatured interest" for purposes of the United States
Bankruptcy Code. Any original issue discount that was not amortized as of any
such bankruptcy filing would constitute "unmatured interest."

LACK OF PUBLIC MARKET FOR THE DISCOUNT NOTES

     There is no public market for the Discount Notes. Holdings does not expect
a trading market in the Discount Notes to develop. No broker-dealer presently
intends to make a market in the Discount Notes. No assurances can be given as to
the liquidity of or trading market for the Discount Notes.

                                USE OF PROCEEDS

     The Company will not receive any proceeds from the sale of the Discount
Notes by the selling security holder.

(1) The Company classifies variable compensation paid to employees as cost of
     goods sold. Previously, the Company has classified this cost as selling,
     general and administrative expenses. The Company has made reclassifications
     to the prior periods in order to conform to the current period 
     presentation.

(2) Includes dividend income, charitable contributions, gain (loss) on disposal
    of assets and investment securities, net, and other, net. For the twelve
    months ended May 31, 1996, other expense includes an impairment of
    investment in land of $12.6 million.

(3) Approximately 95% of the Company's butadiene sales are under fixed profit
    contracts with suppliers of crude butadiene.

(4) Includes Clarkston's trading revenues from third parties (for the periods
    prior to July 1, 1996), utility revenues, revenues realized from the
    Company's terminalling facilities and sales of chemical by-products.

(5) Volumes in millions of gallons.

(6) EBITDA represents income before income taxes, extraordinary loss and
    minority interest before taking into consideration interest expenses,
    depreciation and amortization and certain other non-recurring charges.
    EBITDA is presented because it is a widely accepted financial indicator of a
    company's ability to incur and service debt. EBITDA should not be construed
    by an investor as an alternative to income from operations (as determined in
    accordance with generally accepted accounting principles), as an indicator
    of the operating performance of the Company or as an alternative to cash
    flows from operating activities (as determined in accordance with generally
    accepted accounting principles) as a measure of liquidity.

(7) For purposes of this ratio, earnings consist of income before income taxes
    and minority interest. Fixed charges consist of interest expense and the
    portion of rents representative of an interest factor. For the twelve months
    ended May 31, 1996, income before taxes and minority interest includes a
    $12.6 million non-cash provision for the impairment of certain non-strategic
    properties which TPC intends to sell. For the year ended June 30, 1997 and
    the six months ended December 31, 1996, earnings were insufficient to cover
    fixed charges by the amount of $18.8 million and $7.8 million, respectively.

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

OVERVIEW

     The Company's revenues are derived primarily from merchant market sales of
butadiene, MTBE, n-butylenes (butene-1 and butene-2) and specialty isobutylenes
(isobutylene concentrate, high purity isobutylene, and diisobutylene). The
Company's results of operations are affected by a number of factors, including
variations in market demand, production volumes, and the pricing of its products
and primary raw materials. The Company believes that the pricing for its
principal products is primarily dependent on the balance between the global
supply and North American demand for each product, the cost structure of the
various global producers (including their cost of raw materials), and, from time
to time, other external factors, such as the implementation of the CAAA, which
has significantly increased the demand for MTBE. Historically, the Company has
successfully mitigated the cyclicality of the markets for certain of its end
products by entering into contracts with pricing which allows for a fixed profit
by linking prices directly or indirectly to raw material costs. In addition, the
Company has attempted to optimize the use of isobutylene, an intermediate
feedstock produced by the Company, to produce MTBE or higher margin, specialty
products depending on prevailing market conditions. The Company's margins in
fiscal 1997 were negatively impacted by the higher cost of raw materials. The
cost of raw materials moderated at the end of the fiscal year and returned to
more historical levels.

REVENUES
   
     The Company's revenues are primarily a function of the volume of products
sold by the Company and the prices for such products. The following tables set
forth the Company's: (i) historical revenues and the percentages of historical
revenues by product; (ii) volume of products sold; and (iii) average selling
prices for such products, exclusive of tolling fees, in each case for the year
ended May 31, 1995, the twelve-month period ended May 31, 1996, the one-month
period ended June 30, 1996, the year-ended June 30, 1997 and the six months
ended December 31, 1996 and 1997.

SIX MONTHS ENDED DECEMBER 31, 1997 COMPARED TO THE SIX MONTHS ENDED DECEMBER 31,
1996
    
  REVENUES
   
     The Company's revenues increased by approximately 12%, or $29.8 million, to
$276.5 million for the six months ended December 31, 1997 from $246.7 million
for the six months ended December 31, 1996. Butadiene sales revenues increased
approximately 16% as a result of higher sales volumes. Butadiene sales continue
to remain strong as a result of market demand and increased production levels.
MTBE sales revenues were lower as a result of lower sales volumes during the
current period partially offset by higher sales prices. Sales volumes of MTBE
are lower due to the shift in isobutylene production, an intermediate
    
                                       20
<PAGE>
feedstock, to the production of isobutylene concentrate. Sales volumes of
isobutylene concentrate have returned to more historical levels due to
improvements in market fundamentals. Sales of high-purity isobutylene and
diisobutylene were relatively unchanged. N-butylene sales revenue increased
significantly due to higher sales volumes. Sales volumes of butene-1 increased
due to an unplanned shutdown of a major competitor in the market. The Company
was able to successfully increase its butene-1 production rates to meet this
demand from customers. Sales volumes of butene-2 to the chemical market also
increased during the current year.

  GROSS PROFIT
     Gross profit increased by approximately 95%, or $12.3 million, to $25.2
million for the six months ended December 31, 1997 from $12.9 million for the
six months ended December 31, 1996. Gross margin during this period increased to
9.1% from 5.2%. This increase was primarily attributable to higher MTBE margins
and increased sales volumes of n-butylenes and specialty isobutylenes. MTBE
average sales prices were higher during the current period compared to the prior
period due to a shortage of prompt MTBE bbls. in the market and a strong driving
season. MTBE margins also improved as a result of lower feedstock costs.

  INCOME FROM OPERATIONS
     Income from operations increased by approximately 118%, or $11.9 million,
to $22.0 million for the six months ended December 31, 1997 from $10.1 million
for the six months ended December 31, 1996. Operating margin during this period
increased to 8.0% from 4.1%. This increase in income from operations and
operating margin was primarily due to the same factors contributing to the
increase in gross profit and gross margin described above.

  SELLING, GENERAL AND ADMINISTRATIVE EXPENSES
   
     Selling, general and administrative expenses increased approximately $0.4
million, to $3.2 million for the six months ended December 31, 1997 from $2.8
million for the six months ended December 31, 1996. The increase in selling,
general and administrative expenses was associated with increased business
development activity in the current period.
    
YEAR ENDED JUNE 30, 1997 COMPARED TO THE TWELVE MONTHS ENDED MAY 31, 1996

  REVENUES

     The Company's revenues increased by approximately 8%, or $34.6 million, to
$490.2 million for the year ended June 30, 1997 from $455.6 for the twelve
months ended May 31, 1996. The increase was primarily attributable to increased
sales volumes of MTBE and butadiene, partially offset by decreases in sales
volume of specialty isobutylenes.

     Butadiene revenues increased by approximately 16%, or $18.3 million, to
$130.9 for the year ended June 30, 1997 from $112.6 million for the twelve
months ended May 31, 1996. The increase was attributable to an increase in sales
volume of approximately 21%, or 127.7 million pounds, as a result of increased
production levels due to the availability of crude butadiene, processing
efficiencies and strong customer demand. The volume increase was partially
offset by a decline in butadiene sales prices. Prices declined slightly in the
current year as a result of the build up of U.S. tire inventory to record levels
in the prior year.

     MTBE revenues increased by approximately 23%, or $42.9 million, to $230.3
million for the year ended June 30, 1997 from $187.4 million for the twelve
months ended May 31, 1996. With the decrease in demand for isobutylene
concentrate for the first half of the fiscal year, the Company shifted its
isobutylene production, an intermediate feedstock, to the production of MTBE.
Demand for MBTE in the market remained strong, allowing the Company to supply
increased volumes to its customers.

     n-Butylenes revenues increased by approximately 2%, or $1.2 million, to
$49.4 million for the year ended June 30, 1997 from $48.2 million for the twelve
months ended May 31, 1996. Sales volumes and prices of butene-1 increased in the
current year compared to the prior. The increases were the result of

                                       21
<PAGE>
strong demand from polyethylene producers and successful marketing efforts by
the Company. Sales volumes of butene-2 decreased in the current year as a result
of alternative feedstocks entering the market.

     Specialty isobutylene revenues decreased by approximately 16%, or 12.2
million, to $62.3 million for the year ended June 30, 1997 from $74.5 million
for the twelve months ended May 31, 1996. The decrease was primarily
attributable to lower sales volumes of isobutylene concentrate. Product demand
was adversely affected in the first half of the year by high isobutane prices.
Significant improvements in isobutane pricing and demand occurred in the latter
half of the year. Sales revenues for high purity isobutylene and diisobutylene
decreased in the current year as a result of lower sales prices and slightly
lower sales volumes due to market competition.

     Other revenues decreased by approximately 47%, or $15.6 million, to $17.3
million for the year ended June 30, 1997 from $32.9 million for the twelve
months ended May 31, 1996. The decrease in revenues is due to the elimination of
a former affiliate's trading revenues from third parties. The affiliate was
dissolved in June 1996 as part of the Acquisition.

  GROSS PROFIT
   
     Gross profit decreased by approximately 51%, or $25.2 million, to $24.4
million for the year ended June 30, 1997 from $49.6 million for the twelve
months ended May 31, 1996. Gross margin during the period decreased to 5.0% from
10.9%. The decrease was primarily attributable to lower margins on MTBE and
specialty isobutylene sales. MTBE margins were adversely affected by higher
feedstock costs. Average isobutane and methanol prices were approximately 13%
and 25% higher, respectively, than in the prior year. In December 1996, as a
result of the decline in MTBE margins, the Company shut down for 52 days its
Dehydro-1 unit which has a production capacity of approximately 9,000 barrels
per day of isobutylene. Additionally, during October 1996, the Company
temporarily shut down Dehydro-1 for 21 days as a result of a scheduled
turnaround in order to install a new waste heat boiler. Higher natural gas
prices also contributed to a lower gross profit during fiscal 1997. Gross
profits from sales of butadiene and butene-1 increased over the prior year,
along with lower variable compensation paid to employees, and were used to
offset partially the above referenced decrease. Gross profit was also negatively
impacted by increased depreciation and amortization expense during fiscal 1997
as a result of the increased basis in fixed assets and goodwill from the
Acquisition.
    
  INCOME FROM OPERATIONS

     Income from operations decreased by approximately 56%, or $23.7 million, to
$18.3 million for the year ended June 30, 1997 from $42.0 million for the twelve
months ended May 31, 1996. Operating margin during the period decreased to 3.7%
from 9.2%. This decrease in income from operations and operating margin was
primarily due to the same factors contributing to the decrease in gross profit
and gross margin described above. The decrease was partially offset by a
decrease in selling, general and administrative costs as a result of cost
savings subsequent to the Acquisition.

  INTEREST EXPENSE

     Interest expense increased by approximately $37.8 million, to $39.4 million
for the year ended June 30, 1997 from $1.6 million for the twelve months ended
May 31, 1996. The increase in interest expense was associated with long-term
debt incurred by the Company as a result of the Acquisition.

ONE MONTH ENDED JUNE 30, 1996 COMPARED TO ONE MONTH ENDED JUNE 30, 1995

  REVENUES

     The Company's revenues increased by approximately 14%, or $5.2 million, to
$41.4 million for the one month ended June 30, 1996 from $36.2 million for the
one month ended June 30, 1995. This increase was attributable to increased
volumes for butadiene and MTBE. Volumes for n-butylenes and specialty
isobutylenes were down compared to the prior period. Prices for butadiene were
up slightly and MTBE prices were down. Other product prices remained constant
with the prior period.

                                       22
<PAGE>
  GROSS PROFIT
   
     Gross profit decreased by approximately 23%, or $1.1 million, to $3.7
million for the one month ended June 30, 1996 from $4.8 million for the one
month ended June 30, 1995. Gross margin during this period decreased slightly to
9.0% from 13.2%. The decline in gross profit was primarily attributable to the
decreased sales price of MTBE.
    
  INCOME FROM OPERATIONS

     Income from operations decreased by approximately 27%, or $0.9 million, to
$2.4 million for the one month ended June 30, 1996 from $3.3 million for the one
month ended June 30, 1995. Operating margin during this period declined to 5.9%
from 9.2%. This decrease in income from operations and operating margin was
primarily due to the same factors contributing to the decrease in gross profit
and gross margin described above.

TWELVE MONTHS ENDED MAY 31, 1996 COMPARED TO YEAR ENDED MAY 31, 1995

  REVENUES

     The Company's revenues decreased by approximately 4%, or $19.1 million, to
$455.6 million for the twelve months ended May 31, 1996 from $474.7 million for
the year ended May 31, 1995. This decrease was primarily attributable to
decreased selling prices for butadiene, MTBE and n-butylenes, as well as
decreased sales volumes for specialty isobutylenes and a decrease in other
revenues, partially offset by increased selling prices of specialty isobutylenes
as well as increased sales volumes of butadiene, MTBE and n-butylenes.

     Butadiene revenues increased by approximately 6%, or $6.4 million, to
$112.6 million for the twelve months ended May 31, 1996 from $106.2 million for
the year ended May 31, 1995. This increase was primarily attributable to an
increase in sales volumes of approximately 7%, or 41.8 million pounds, as a
result of increased contractual volumes sold at then current prices to a major
customer as the Company gained a larger share of this customer's business and as
this customer increased its requirements. In addition, sales prices decreased
slightly due to customers drawing down inventory thereby decreasing overall
product demand.

     MTBE revenues decreased by approximately 6%, or $11.7 million, to $187.4
million for the twelve months ended May 31, 1996 from $199.1 million for the
year ended May 31, 1995. This decrease was primarily attributable to a decrease
in selling prices due to the expiration of significant sales contracts in which
pricing was based on a fixed profit above cost, in accordance with industry
trends. In addition, sales volumes increased by approximately 4%, or 8.7 million
gallons, due to the full year implementation of mandated oxygenate requirements.

     n-Butylenes revenues increased by approximately 13%, or $5.5 million, to
$48.2 million for the twelve months ended May 31, 1996 from $42.7 million for
the year ended May 31, 1995. This increase was attributable to increased sales
volumes of approximately 16%, or 38.7 million pounds, as the Company expanded
its customer base and increased its contractual volumes to a significant
existing customer. A decrease in average selling prices resulted from the
Company matching competitors' pricing for certain products, which partially
offset the increase in sales volumes.

     Specialty isobutylenes revenues decreased by approximately 1%, or $1.0
million, to $74.5 million for the twelve months ended May 31, 1996 from $75.5
million for the year ended May 31, 1995. This decrease was the result of a major
specialty isobutylene customer increasing purchases of a low price specialty
isobutylene product from a competing supplier offering an alternate, lower
purity product during this period. The Company offset a portion of these lower
volumes by sales of higher priced specialty isobutylene products to other
customers at prices which were lower than prevailing contract prices.

     Other revenues decreased by approximately 36%, or $18.3 million, to $32.9
million for the twelve months ended May 31, 1996, from $51.2 million for the
year ended May 31, 1995. This decrease was primarily due to a $17.5 million
decrease in sales from Clarkston to third parties due to reduced n-butane and
isobutane trading activity.

<PAGE>
  GROSS PROFIT
   
     Gross profit decreased by approximately 11%, or $6.0 million, to $49.6
million for the twelve months ended May 31, 1996 from $55.6 million for the year
ended May 31, 1995. Gross margin during this period decreased slightly to 10.9%
from 11.7%. The decline in gross profit was primarily attributable to a one-time
10% salary increase for employees included in cost of goods sold, higher
variable compensation paid to employees, and to an additional $3 million
increase in cost of goods sold resulting from a scheduled maintenance shutdown
on one of the Company's dehydrogenation units and the write-off of capitalized
dehydrogenation catalyst costs, which resulted from an unscheduled shutdown. In
addition, depreciation and amortization increased slightly related to new
capital investments. These cost increases were partially offset by a decrease in
raw material methanol costs and a decrease in costs associated with Clarkston's
third party trading activities during this period.
    
  INCOME FROM OPERATIONS
   
     Income from operations decreased by approximately 12%, or $5.5 million, to
$42.0 million for the twelve months ended May 31, 1996 from $47.5 million for
the year ended May 31, 1995. Operating margin during this period declined to
9.2% from 10.0%. This decrease in income from operations and operating margin
was primarily due to the same factors contributing to the declines in gross
profit and gross margin described above. See "-- Liquidity and Capital
Resources."

the six months ended December 31, 1997 compared to $(0.1) million for the six
months ended December 31, 1996. The change of $21.8 million was attributable to
increased profitability offset by changes in working capital as a result of
timing differences in receipts and disbursements of cash. Net cash used in
investing activities was $3.4 million for the six months ended December 31, 1997
compared to $353.6 million for the six months ended December 31, 1996. The
decrease of $350.2 million was attributable to the Acquisition of the Company
during the prior year. Net cash provided by (used in) financing activities was
$(18.3) million for the six months ended December 31, 1997 compared to $353.9
million for the six months ended December 31, 1996. The change of $372.2 million
was attributable to the financing of the Acquisition of the Company during the
prior year.
    
YEAR ENDED JUNE 30, 1997 COMPARED TO THE TWELVE MONTHS ENDED MAY 31, 1996

     Net cash provided by (used in) operating activities was $(1.8) million for
the year ended June 30, 1997 compared to $44.5 million for the twelve months
ended May 31, 1996. The change of $46.3 million was primarily attributable to
the decrease in overall profitability and changes in working capital. Net cash
provided by (used in) investing activities was $(352.3) million for the year
ended June 30, 1997 compared to $8.2 million for the twelve months ended May 31,
1996. The change of $360.5 million was primarily attributable to the Acquisition
on July 1, 1996, partially offset by proceeds from the sale of non-plant assets
and Company assets and investments. Net cash provided by (used in) financing
activities was $354.2 million for the year ended June 30, 1997 compared to
$(69.0) million for the twelve months ended May 31, 1996. The change of $423.2
million was primarily attributable to the issuance of long-term debt and an
investment from Holdings, in order to finance the Acquisition.

ONE MONTH ENDED JUNE 30, 1996 COMPARED TO ONE MONTH ENDED JUNE 30, 1995

     Net cash provided by operating activities was $13.9 million for the one
month ended June 30, 1996 compared to $1.9 million for the one month ended June
30, 1995. This increase of $12.0 million was primarily attributable to changes
in working capital, partially offset by a decrease in net income. Net cash used
in investing activities was $1.3 million for the one month ended June 30, 1996
compared to net cash

provided by investing activities of $5.9 million for the one month ended June
30, 1995. This change of $7.2 million was due to an increase in capital
expenditures and a decrease in proceeds from sales of investment securities. Net
cash used in financing activities was $9.4 million for the one month ended June
30, 1996 compared to $4.5 million for the one month ended June 30, 1995. This
increase of $4.9 million was primarily due to a decrease in bank overdrafts
partially offset by an increase in borrowings under revolving credit lines, a
decrease in payments of notes payable and a decrease in dividends paid.

TWELVE MONTHS ENDED MAY 31, 1996 COMPARED TO YEAR ENDED MAY 31, 1995

     Net cash provided by operating activities was $44.5 million for the twelve
months ended May 31, 1996 compared to $50.3 million for the year ended May 31,
1995. This decrease of $5.8 million was primarily attributable to a decrease in
net income adjusted for non-cash items and a decrease in changes in working
capital. Net cash provided by investing activities was $8.2 million for the
twelve months ended May 31, 1996 compared to net cash used in investing
activities of $25.9 million for the year ended May 31, 1995. This change of
$34.1 million was due to decreases in capital expenditures, an increase in
proceeds from the sales of investment securities and a decrease in purchases of
investment securities. Net cash used in financing activities was $69.0 million
for the twelve months ended May 31, 1996 compared to $23.3 million for the year
ended May 31, 1995. This increase of $45.7 million was primarily due to the
purchase by the Company of common stock for a total consideration of $95.4
million in August 1995 and an increase in dividends and distributions paid,
partially offset by the sale by the Company of common stock to certain officers
of the Company for $22.6 million and decreased repayments under revolving credit
lines.

LIQUIDITY
   
     The Company's liquidity needs arise primarily from principal and interest
payments under the $140 million Bank Credit Agreement and $175 million principal
amount of Original Notes incurred in connection with the Acquisition, as well as
the $50 million principal amount of Notes, the net proceeds of which were used
to reduce indebtedness under the Bank Credit Agreement. The Company's primary
source of funds to meet debt service requirements is net cash flow provided by
operating activities. Operating cash flow is significantly impacted by raw
materials cost as well as the selling price and volume variances of finished
goods. The Company enters into supply contracts for certain of its products in
order to mitigate the impact of changing prices. Additionally, the Company has a
$40 million Revolving Credit Facility of which only $5 million was in use at
December 31, 1997, to provide adequate funds for ongoing operations, working
capital, planned capital expenditures and debt service during the terms of such
Revolving Credit Facility. The Company believes that the availability of funds
under the Revolving Credit Facility are sufficient to cover any current
liquidity needs which could arise as a result of negative working capital. The
Company's ability to borrow is limited by the terms of the Bank Credit Agreement
and the Notes Indenture and the Discount Notes Indenture. The Bank Credit
Agreement, the Original Notes, the Notes, and the Discount Notes include certain
restrictive covenants which include, but are not limited to, limitations on
capital expenditures, indebtedness, investments and sales of assets and
subsidiary stock. Additionally, the Bank Credit Agreement requires the Company
to maintain certain financial ratios. On July 31, 1997 the Company obtained an
amendment to the Bank Credit Agreement to waive the debt to EBITDA ratio at June
30, 1997 and to update the financial ratios relating to fixed charge coverage
and debt to EBITDA for fiscal 1998. See "Risk Factors -- "Restrictive
Financing Covenants," "Description of the Bank Credit Agreement" and
"Description of the Discount Notes."
    
CASH BONUS PLAN

     In connection with the Acquisition, the Company established the $35 million
Cash Bonus Plan covering substantially all employees of the Company (or certain
affiliates of the Company) and covering the employees of certain third-party
contractors who have contributed to the success of the Company. All participants
of the plan as of July 2, 1996 were distributed 10% of the cash bonus in August
1996, and the remaining amount is to be paid in sixteen quarterly installments
which began in October 1996.

CAPITAL EXPENDITURES
   
     Capital expenditures for the six months ended December 31, 1997 were $4.5
million. These expenditures relate principally to improving operating
efficiencies and maintaining environmental compliance. The Company is planning
capital projects for the remainder of fiscal 1998 in the areas of process
automation, operating efficiencies, system integration and environmental
compliance. The Company anticipates capital expenditures for fiscal 1998 to be
approximately $14 million. Capital expenditures for the year ended June 30, 1997
were $7.6 million, compared to $5.5 million for the twelve months ended May 31,
1996 and $8.7 million for the year ended May 31, 1995. The Company's capital
expenditures for fiscal 1997 related principally to improving operating
efficiencies and maintaining environmental compliance (including the
installation of an environmentally superior waste-heat boiler in one of the
Company's dehydrogenation units). The Company expenses approximately $20 million
annually for plant maintenance. These maintenance costs are not treated as
capital expenditures.
    
RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

     During 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards ("SFAS") No. 128 "Earnings per Share," SFAS
No. 129 "Disclosure of Information about Capital Structure," SFAS No. 130,
"Reporting Comprehensive Income," and SFAS No. 131, "Disclosures about
Segments of an Enterprise and Related Information." SFAS No. 128 is effective
for financial statements for both interim and annual periods ending after
December 15, 1997. SFAS No. 129 is effective for periods ending after December
15, 1997. SFAS No. 130 and SFAS 131 are effective for fiscal years beginning
after December 15, 1997. Adoption of these pronouncements is not expected to
have a material effect on the Company's financial position, results of
operations or cash flows.

OTHER

     In March 1995, the Financial Accounting Standards Board issued SFAS No.
121 -- "Accounting for the Impairment of Long-Lived Assets and for Long-Lived
Assets to be Disposed Of" (the "Standard"). The Standard requires, among
other things, that long-lived assets and certain identifiable intangibles to be
held and used by an entity be reviewed for impairment whenever events or changes
in circumstances indicate that the carrying amount of an asset may not be
recoverable. During 1996, the Company evaluated the carrying value of its
investments in land in light of the possible sale of these assets in the
foreseeable future and considering the criteria in the Standard, determined that
an impairment write-down was necessary. Prior to 1996, the Company did not
consider the decline in the fair value of those assets, which was below the
Company's cost, to be a permanent decline. During the twelve months ended May
31, 1996 the Company adopted the Standard and as a result recorded a provision
of $12,592,112, with an associated tax benefit of $4,660,000, to write down
certain properties to estimated fair market value. As of September 30, 1997 the
Company still holds two properties and is marketing these properties for sale.
The carrying value of the properties at September 30, 1997 was $2.6 million.
There have been no changes in the market to indicate that further revisions to
the carrying value of these assets is necessary.

                                    BUSINESS

GENERAL

     The Company is the largest producer of butadiene and butene-1, and the
third largest producer of MTBE, in North America, in terms of production
capacity. In addition, the Company is the sole producer of diisobutylene and
isobutylene concentrate in the United States and the largest domestic merchant
supplier of high purity isobutylene to the chemical market. The Company's
products include: (i) butadiene, primarily used to produce synthetic rubber;
(ii) MTBE, used as an oxygenate and octane enhancer in gasoline; (iii) n-
butylenes (butene-1 and butene-2), used in the manufacture of plastic resins,
fuel additives and synthetic alcohols; and (iv) specialty isobutylenes,
primarily used in the production of specialty rubbers, lubricant additives,
detergents and coatings. For the year ended June 30, 1997, and the twelve months
ended May 31, 1996, butadiene represented 27% and 25% of the Company's total
revenues, respectively, MTBE represented 47% and 41%, n-butylenes 10% and 11%,
respectively, specialty isobutylenes 13% and 16%, respectively and other
revenues the remaining 3% and 7%, respectively. The Company's revenues for the
year ended June 30, 1997, the twelve months ended May 31, 1996 and the one month
ended June 30, 1996 were $490.2 million, $455.6 million and $41.4 million,
respectively, and EBITDA (as defined) for the year ended June 30, 1997, the
twelve months ended May 31, 1996 and the one month ended June 30, 1996 were
$50.4 million, $57.0 million and $3.7 million, respectively.

     Butadiene is the most widely used feedstock for synthetic rubber products
and is also used in the manufacture of engineered plastics, nylon fibers and
other products. The Company sells butadiene to a stable customer base ,
including The Goodyear Tire & Rubber Company, The Dow Chemical Company, American
Synthetic Rubber Inc. and Bridgestone/Firestone, Inc. As the largest producer of
butadiene in North America, the Company believes that many of its customers
place significant value on its ability to provide a reliable domestic supply of
butadiene and as a result have entered into long-term sales contracts with the
Company.

     The Company extracts butadiene from crude butadiene, which is generated
from the production of ethylene and is comprised of a number of valuable
components, including butadiene, isobutylene, n-butylenes, isobutane and
n-butane. Many U.S. ethylene producers rely on third parties such as the Company
to process their crude butadiene streams, as the crude butadiene volumes they
produce are not sufficient to justify the construction of on-site butadiene
recovery facilities. The Company estimates that producers accounting for 65% of
U.S. and Canadian ethylene production capacity do not internally process crude
butadiene by-product streams. The Company is the largest non-integrated crude
butadiene processor in North America and as a result of its strategic importance
to ethylene producers, the Company has been able to secure long-term supply
contracts covering the majority of its crude butadiene requirements. Such
contracts provide for a fixed profit based on the Company's selling prices for
butadiene, and account for the relatively stable profitability of the Company's
butadiene operations.

     MTBE is a blending stock which reduces carbon monoxide and volatile organic
compound emissions and enhances the octane content of gasoline, and has been one
of the fastest growing petrochemicals, in terms of volume, over the past fifteen
years. Today, MTBE is the preferred oxygenate for, and a major component of, RFG
and is used in over 30% of the U.S. gasoline pool. MTBE is produced by reacting
methanol and isobutylene, and the Company's ability to produce isobutylene by
three alternative methods enables it to produce MTBE by the most economical
processes available to the Company. In addition, the Company has the ability to
add incremental isobutylene capacity to capitalize on expected future growth, at
a significantly lower cost than new grass root, on-purpose capacity. The Company
believes that this incremental capacity gives it a competitive advantage over
other producers who would have to incur greater cost to increase capacity. The
Company sells MTBE to oil refiners and gasoline producers, including Mobil Oil
Corporation, Lyondell Petrochemical Company and CITGO Petroleum Corporation on
both a contract and spot basis at prices linked to prevailing market prices.

     The Company is the leading producer of high margin n-butylenes and
specialty isobutylenes in North America. In recent years, the Company has
increased its sales of these products by increasing its market share in
polyolefin applications and the development of new end-use applications. The
Company's principal

                                       27
<PAGE>
customers for n-butylenes include Union Carbide Corporation, The Dow Chemical
Company, NOVA Chemicals Ltd., Shell Chemical Company and Lyondell Petrochemical
Company. The Company's principal customers for specialty isobutylenes include
Bayer Inc., Mobil Chemical Company Inc., Rhone-Poulenc Inc., The Lubrizol
Corporation and Schenectady International, Inc. Historically, the profitability
of the Company's n-butylenes sales has been relatively stable as the majority of
the sales of these products are made under contracts which link their selling
prices to the prices of products (principally gasoline and butanes) whose prices
fluctuate closely with those of the raw materials used to manufacture
n-butylenes and specialty isobutylenes.

     The Company's principal feedstocks are crude butadiene, isobutane and
methanol. One of the Company's intermediate feedstocks, isobutylene, is used in
the manufacture of MTBE and specialty isobutylenes. As part of its production
strategy, the Company uses its manufactured isobutylene first to maximize the
production of high margin specialty isobutylenes, second, to satisfy its
contractual MTBE requirements, and finally, to produce MTBE for sale in the spot
market. In addition, the Company maintains the production flexibility to upgrade
n-butylenes contained in crude butadiene streams to either isobutylene or
butene-1 using its patented SKIP process. This flexibility allows the Company to
meet its customers' needs through the most economical process, to produce
additional products and to capitalize on favorable market conditions.

     The Company's manufacturing facility, located approximately one mile from
the Houston Ship Channel, provides convenient access to other Gulf Coast
petrochemical producers and is connected to several of its customers and raw
materials suppliers through an extensive pipeline network. In addition, the
Company's facility is serviced by rail, tank truck and barge.

     The Company was founded in 1968, at which time the Company was principally
engaged in the installation of crude butadiene processing facilities. In 1984,
the Company acquired from Tenneco, Inc. the assets (principally comprised of the
Houston facility) of Petro-TexChemical Corporation ("Petro-Tex"), the prior
owner of the Company's manufacturing facility.

COMPANY STRATEGY

     The Company believes that it has become the industry leader in the
production of the majority of its products by capitalizing on its production
flexibility, its ability to add significant incremental capacity across its
product lines, the marketing experience of its management team, its competitive
cost position and its customer focus. The Company's strategy is to strengthen
its established presence in its selected markets by focusing on the following
factors:

     REDUCE EXPOSURE TO CYCLICAL END-MARKETS -- The markets in which the Company
competes are cyclical. The Company intends to mitigate the effects of this
cyclicality while benefiting from potential upturns in industry profitability by
optimizing the proportion of its sales made under contracts allowing for a fixed
profit or at prices linked directly or indirectly to raw material prices.

     CAPITALIZE ON PRODUCTION FLEXIBILITY -- The Company has the ability to
produce a number of its intermediate and finished products (I.E. crude
butadiene, isobutylene and butene-1) by a variety of processes. The Company
intends to capitalize on this ability by shifting production to the most
economical process and production level based upon market conditions, thus
ensuring a reliable source of supply for its customers.

     UTILIZE INCREMENTAL CAPACITY -- The Company can increase its capacity to
produce butadiene, isobutylene and its derivatives at significantly lower cost
than that of new construction. While the Company currently has no plans to
increase its production capacity, it continuously evaluates these strategic
options in light of prevailing market conditions. In addition, the Company
believes that its ability to add low-cost incremental capacity acts as a
deterrent to other producers and new entrants considering capacity expansions.

     The Company's ability to add incremental butadiene capacity and its
relationships with several North American ethylene producers are expected to
enable it to capture the benefit of increased U.S. crude

                                       28
<PAGE>
butadiene supply. In addition, announced butadiene capacity expansions by other
U.S. producers are minimal. The Company believes that growth in global demand
for butadiene will be consistent with gross domestic product growth based on
increased tire production and potential substitution of synthetic rubber for
natural rubber.

     RESPOND TO FAVORABLE INDUSTRY DYNAMICS -- The Company's production
flexibility and its ability to add low-cost capacity are crucial to its
capitalizing on the attractive demand/supply outlook for a number of its
products.

      o   BUTADIENE.  The U.S. supply of crude butadiene is increasing in line
          with domestic ethylene production, although it is currently
          insufficient to meet U.S. demand. Industry operating rates are
          expected to remain at current high levels as the increase in domestic
          crude butadiene production is expected to replace imports with
          butadiene demand remaining strong in support of derivative businesses.

      o   MTBE.  While the Company expects U.S. demand for MTBE to grow less
          quickly than it has over the past fifteen years, it believes that
          future growth in foreign demand may be considerable. In addition,
          recently announced U.S. MTBE capacity additions are minimal.

      o   BUTENE-1.  Demand for butene-1 is closely linked to polyethylene
          production growth. The Company expects global production of
          polyethylene to increase at higher than historical rates in the next
          four years. In addition, the Company expects demand for butene-1 used
          in other applications to be strong.

     SUSTAIN CUSTOMER FOCUS -- The Company believes that producing quality
products and providing quality service with dependable supply are key factors in
its ability to compete in the market place for its products. Management believes
that its focus on customer service has resulted in strong customer relationships
and a high degree of customer loyalty. This is evidenced by the fact that
approximately 60% of the Company's current customers have purchased products
from the Company for more than ten years.

INDUSTRY OVERVIEW

     BUTADIENE.  Butadiene is an important raw material used in the production
of a number of products, including styrene-butadiene rubber ("SBR"),
polybutadiene rubber, styrene-butadiene ("SB") latex, acrylonitrile butadiene
styrene ("ABS") and hexamethylenediamine ("HMDA"). These products are
utilized in the manufacture of tires and other rubber products, engineered
plastics, nylon fibers and other uses.

     Demand for butadiene depends to a large extent on trends in the housing and
automotive sectors, principally the replacement tire market. The tire
replacement market has historically been less cyclical than the market for
original equipment tires and accounts for approximately 75% of all U.S. car and
commercial vehicle tire production. The Company expects continued growth in
butadiene end-use demand over the next several years consistent with global
gross domestic product growth. The Company believes that U.S. tire production
could increase as a result of higher volumes of domestic automobile production
due to foreign "transplant" production.

     The most important butadiene derivative is SBR, which is primarily used in
the manufacture of tires, gaskets and hoses. Since 1990, the demand for SBR has
increased at a compound annual growth rate of approximately 3%. Although SBR
markets are mature, the Company expects that demand for higher performance tires
and truck tires may contribute to growth in demand for SBR at higher than
historical levels.

     Polybutadiene rubber provides higher abrasion resistance than other rubbers
which makes it preferential for high performance tires, plastics applications
and other heavy duty uses. Other types of synthetic rubber produced from
butadiene include polychloroprene rubber, used in wire and cable applications,
and nitrile rubber, which, due to its high tensile strength and abrasion
resistance, is used in specialty applications, such as hoses, tubes and belts.

     Butadiene derivatives which are not used to produce synthetic rubber
primarily consist of HMDA, SB latex and ABS. Historically, demand for these
products has generally reflected global gross domestic product growth. HMDA is
an intermediate in the production of nylon fiber. SB latex demand is driven by
its use in paints, adhesives and paper coatings. ABS resins are used in the
production of high-performance plastics with a wide range of applications in the
automotive, appliance and electronics industries.

     Butadiene producers are currently operating at historically high rates and
the Company believes that no new capacity is expected to come on-line in the
U.S. in the next five years. Management believes that the Company's existing
capacity and low-cost expansion alternatives act as an effective deterrent to
the construction of new facilities by others in the United States.

     The major source of supply for butadiene is extraction from crude
butadiene, a by-product of ethylene production. In the U.S., volumes of crude
butadiene from ethylene facilities are inadequate to meet domestic demand. The
U.S. imports a large portion of its requirements of butadiene and crude
butadiene, especially from Western Europe, where most ethylene facilities use
feedstocks which result in the production of proportionately more crude
butadiene than in the U.S. Historically, the price of butadiene has been
determined by supply, which is influenced by the amount of ethylene produced and
the availability of crude butadiene, and butadiene demand, which is determined
by demand for end-use products, such as tires, engineered plastics and nylon
fibers.

     MTBE.  MTBE has been one of the fastest growing petrochemicals, in terms of
volume, during the past fifteen years, with global production rising from
approximately 15,000 barrels per day in 1980 to approximately 382,000 barrels
per day in 1995. MTBE's dramatic growth has been a result of two significant
factors. First, MTBE has a high octane rating, which makes it a valuable
gasoline blendstock for adding octane to gasoline. Second, MTBE contains a high
percentage weight (approximately 18%) of oxygen. Its high oxygen level, which
results in improved combustion and reduces the level of carbon monoxide and
ozone-depleting emissions from automobile engines, contributes to MTBE's use as
a blending agent in oxygenated and reformulated gasolines. These properties and
its large scale global production capacity have made it the preferred oxygenate
and a major component of RFG in the U.S.

                                       31
<PAGE>
     The use of lead additives in gasoline declined dramatically during the
1980s as a result of environmental legislation. Following such legislation,
octane needs increased, which increased world MTBE use considerably. The passage
of the CAAA in 1990 in the U.S. has caused another round of MTBE production
capacity additions and blending use increases during the past four years.

     The two programs mandated by the CAAA which have the most significant
effect on the MTBE market are the oxygenated gasoline and the RFG programs. The
oxygenated gasoline program was initiated in 1992, with the goal of reducing
winter carbon monoxide emissions. With the implementation of the RFG program in
1995, the use of RFG was required in the nine major urban areas with the most
severe ozone pollution. High RFG prices and public health concerns, particularly
in cold weather climates, kept MTBE use below the levels that had been
anticipated in the industry at the time of the passage of the CAAA. Despite the
problems with the implementation of the CAAA, the Company expects continued
growth in the use of MTBE, although at slower rates than in the 1980s as the
regulations requiring "cleaner" gasoline have, in large measure, gone into
effect in the U.S. The Company anticipates that higher rates of growth in MTBE
use will continue to prevail in certain regions of the U.S. and internationally,
due to consumer preference or where RFG use is now optional but may be required
by state or local governments. For example, California has mandated greater
usage of oxygenates in a gasoline reformulated for use in that state, and the
use of lead in gasoline continues to decline in certain European, South American
and Far Eastern countries. The Company also expects new capacity expansions to
be minimal over the next several years due to current industry overcapacity as a
result of large increases in U.S. production capacity in the early 1990s in
anticipation of the implementation of the CAAA programs.

     MTBE pricing is primarily determined by the price of RFG due to its value
as an octane enhancer and as an oxygenate. The price difference between regular
unleaded and higher octane, premium unleaded gasoline provides a valuation for
octane from which the value of MTBE as an octane enhancer can be derived. At
various times, depending on the supply and demand for MTBE, MTBE pricing enjoys
a premium over this octane value, reflecting its value as an oxygenate. MTBE
pricing is relatively volatile. The MTBE market has experienced alternating
periods of tight supply and rising prices and profit margins, followed by
periods of capacity additions resulting in oversupply and declining prices and
margins. Historically, MTBE was sold in the U.S. under sales contracts which
allowed suppliers to recover raw material costs and earn a fixed profit. Sales
prices under these contracts were higher than the then prevailing spot prices.
Prices decreased substantially from 1985 to 1986 based on low gasoline prices.
As gasoline prices recovered in 1988 and 1989, MTBE prices followed. Prices
increased substantially prior to and during the Persian Gulf war beginning in
late 1990, although prices fell back sharply from 1991 to 1993 as supply
outpaced demand. MTBE prices increased in 1994 due to high methanol prices (that
were passed on to users) until methanol prices decreased significantly in the
first quarter of 1995. More recently, MTBE prices have rebounded from their 1995
lows as a result of much higher demands from the RFG program.

     There are a number of competing oxygenate products to MTBE, including
ethanol, ethyl TERTIARY-butyl ether (ETBE) and TERTIARY-amyl methyl ether
(TAME). However, management believes that MTBE will continue to be the U.S.
gasoline industry's oxygenate of choice due to a number of factors, including
price, available capacity, chemical properties and the EPA's CAAA rules
regarding minimum oxygen content in fuels.

     BUTENE-1.  Butene-1 is used as a comonomer in the production of high
density polyethylene ("HDPE") and linear low density polyethylene ("LLDPE").
Both HDPE and LLDPE are raw materials for the production of trash bags, film
wrap, pipe and plastic containers. Comonomers are added to polyethylene to
improve characteristics such as tear and crack resistance. The Company expects
global HDPE and LLDPE demand to increase at an annual compound growth rate of 6%
and 14%, between 1994 and 1999, respectively. In the U.S., butene-1 is facing
increased competition from other comonomers such as hexene-1 which, although
more expensive than butene-1, improves certain properties of polyethylene
resins. The Company believes that butene-1 demand for use in polyethylene will
continue to grow in line with demand for polyethylene. Historically, pricing of
butene-1 has been determined by demand based on its use as a polyethylene
comonomer, and its competitive position with other comonomers such as hexene-1.

                                       32
<PAGE>
     Butene-1 is also used to produce butylene oxide, a key component of
detergent additive packages used in many gasoline formulations.

     BUTENE-2.  Butene-2 is recovered as part of the crude butadiene stream that
remains after extraction of butadiene, isobutylene and butene-1. The Company
sells purified butene-2 primarily for use in the production of coatings and
plasticizers. Due to the high quality of the butene-2 produced by the Company,
it has historically received a higher than market price.

     ISOBUTYLENE CONCENTRATE.  Isobutylene concentrate is similar to high purity
isobutylene in composition, although its purity is 88% isobutylene compared to
99.9% in high purity isobutylene. The Company markets isobutylene concentrate
for use in the growing lubricant additives business as well as for use in the
production of butyl rubber. The Company is the sole U.S. producer of isobutylene
concentrate.

     HIGH PURITY ISOBUTYLENE.  High purity isobutylene is used in the production
of butyl rubber, which is used to produce tires and in specialty chemical
applications such as in the production of resins, antioxidants, paints and
coatings, synthetic lubricant oils and rubber chemicals. The Company is
currently the largest domestic merchant supplier of high purity isobutylene to
the chemical market and competes with ARCO Chemical Company and Exxon Chemical
Company.

     DIISOBUTYLENE.  Diisobutylene is used primarily as an intermediate in the
manufacturing of alkylphenols for the surfactant and phenolic resins markets.
Other uses include the production of tackifier and ink resins, dispersants for
lubricant oil additives, and rubber and processing chemicals. The Company is the
sole U.S. producer of diisobutylene.

PRODUCTION PROCESS

     The Company's production operations are based on a number of key factors:

      (i)  UPGRADING BY-PRODUCT STREAMS:  The Company has contracted to purchase
           certain volumes of crude butadiene from its suppliers. This volume
           determines the Company's ability to produce butadiene and n-butylenes
           and also provides some isobutylene (typically 10% of total
           isobutylene production) for the production of MTBE and specialty
           isobutylenes.

      (ii)  MAXIMIZING USE OF ISOBUTYLENE:  Under normal operating conditions,
            the Company maximizes isobutylene production from its
            dehydrogenation units. The isobutylene processed is first processed
            into specialty isobutylenes to satisfy customer demand, secondly
            used to produce MTBE to satisfy contractual demand and thirdly, used
            to produce MTBE for sale in the spot market.

     (iii)  INCREMENTAL PRODUCTION CAPABILITY:  The Company has the ability to
            augment its isobutylene and butene-1 production by the processing of
            butene-2 in its SKIP unit, depending on the relative profitability
            from additional isobutylene production (for use in either MTBE or
            specialty isobutylenes) or butene-1 sales. In addition, "on
            purpose" crude butadiene can be produced from butene-2 using the
            OXO-D process, as well as from n-butane using dehydrogenation.

BUTADIENE PRODUCTION PROCESS

     The Company has the largest butadiene production and finishing facilities
in North America and has an annual production capacity of 840 million pounds of
butadiene, representing approximately 18% of U.S. and Canadian production
capacity. In the year ended June 30, 1997, the Company sold and toll-processed
750 million pounds of butadiene.

                                       33
<PAGE>
                    [CHART SHOWING PRODUCTION OF BUTADIENE]

     The Company obtains crude butadiene from three different sources: (i)
purchasing crude butadiene from suppliers; (ii) Oxo-dehydrogenation of
n-butylenes using the Company's patented OXO-D process; and (iii)
dehydrogenation of n-butane.

     The Company primarily produces butadiene from purchased crude butadiene,
which is generally the lowest cost method of production. Such crude butadiene is
a by-product of ethylene production.

     "On-purpose" crude butadiene production involves the synthesis of crude
butadiene from n-butane and n-butylenes using the Company's OXO-D process and
the Houdry dehydrogenation process. The OXO-D process was developed by the
Company using a proprietary catalyst. The OXO-D unit has an annual capacity to
produce up to 400 million pounds of crude butadiene, which can be processed to
extract butadiene. The Company's dehydrogenation units can produce n-butylenes
(instead of isobutylenes under normal configuration) using the Houdry process,
by switching feedstock from isobutane to n-butane. Such n-butylenes can be used
to produce crude butadiene using the OXO-D process. As this method of production
is relatively expensive and reduces the volume of isobutylene available for MTBE
production, it is used only when butadiene pricing makes it economically
attractive.

     The OXO-D unit and its dehydrogenation capabilities give the Company the
only on-purpose butadiene production capability in the U.S. and reinforce the
Company's image with its customers as a reliable source of butadiene under a
wide variety of market conditions.

     The Company's manufacturing flexibility is advantageous for two reasons.
First, the Company is not dependent on any particular feedstock to produce
butadiene and it can therefore provide a reliable source of supply under a
variety of market conditions for its customers. Secondly, it permits the Company
to increase butadiene production in favorable market conditions, subject to the
capacity limitations of the Company's finishing facilities.

     The Company believes that it is currently the only butadiene producer in
North America with the ability to add significant incremental capacity with
minimal capital expenditures. The Company believes that this acts as a deterrent
to new entrants and other producers considering capacity expansions and will
enable the Company to process increased volumes of crude butadiene from new
ethylene facilities which are currently being built in North America.

     The Company also toll processes crude butadiene under contract on behalf of
third parties for a fee which allows the Company to recover its energy
production costs plus a fixed dollar amount. Typically, the Company delivers
finished butadiene to the customer and purchases the other butylenes contained
in the stream, which can be upgraded to higher value uses, such as specialty
isobutylenes, butadiene and n-butylenes.

                                       34
<PAGE>
MTBE PRODUCTION PROCESS

     The Company owns two MTBE units with a combined capacity to produce 25,000
barrels per day, which represents approximately 9% of North American production
capacity. The Company sold an average of 17,873 barrels per day in the year
ended June 30, 1997.

                       [CHART SHOWING PRODUCTION OF MTBE]

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

(1) Raffinate-1 is produced after butadiene has been extracted from purchased
    crude butadiene.

     MTBE is produced by reacting isobutylene and methanol. The Company produces
isobutylene, the principal raw material for MTBE, using any one of three
processes: (i) extraction from raffinate-1, which is produced after butadiene
has been extracted from crude butadiene; (ii) dehydrogenation of purchased
isobutane; and (iii) production from n-butylenes (predominantly butene-2) using
the Company's patented SKIP process. The other primary raw material, methanol,
is purchased from third parties in the spot market and under contract and is
transported to the Company's facility by barge.

     Isobutylene is removed from the raffinate-1 stream by processing
raffinate-1 through the Company's MTBE unit. The MTBE reaction is highly
selective and efficiently removes isobutylene from the stream. The stream
remaining is called raffinate-2.

     The Company has three dehydrogenation units, two of which have been
completely refurbished and are fully operational. Using these two units, the
Company has the ability to produce a total of 18,000 barrels per day of
isobutylene. The Company estimates that the third dehydrogenation unit, with an
additional capacity of 8,000 barrels per day, could be refurbished at a cost of
approximately $100 million, substantially less than the cost of a new
dehydrogenation unit. This refurbishment would increase the Company's capacity
to produce isobutylene for use either in MTBE or specialty isobutylenes by
approximately one third. The Company currently does not have any plans to
undertake this refurbishment, although this could change depending on market
conditions. The Company has fully paid-up rights to the technology used in its
dehydrogenation units and no royalty or other licensing payments are required.
Isobutane is purchased under long-term contract and supplemented with spot
purchases.

                                       35
<PAGE>
     The Company currently has sufficient additional MTBE capacity to enable it
to take advantage of future expected growth. The Company believes that this
additional capacity gives it a competitive advantage over other producers which
would have to incur greater cost to increase capacity.

     The Company's SKIP unit upgrades butene-2 to either butene-1 or isobutylene
depending on requirements. Isobutylene production is normally operated so that a
portion of the isobutylene produced by dehydrogenation is used in the production
of isobutylene concentrate and diisobutylene and the remainder is used to
produce MTBE. In addition, a small amount of MTBE production is used in the
production of high purity isobutylene. The configuration of the plant provides
the flexibility to vary the relative quantities of MTBE and isobutylene products
produced.

N-BUTYLENE PRODUCTION PROCESS

     The Company has the largest butene-1 processing capacity in North America
and has an annual production capacity of 275 million pounds of butene-1,
representing approximately 40% of North American production capacity. In the
year ended June 30, 1997 the Company sold 197 million pounds of butene-1 and 34
million pounds of butene-2.

          [CHART SHOWING PRODUCTION OF BUTANES, BUTENE-2 and BUTENE-1]

- ------------
(1) Raffinate-1 is produced after butadiene has been extracted from purchased
    crude butadiene.

     The Company has the ability to produce butene-1 using two different
processes: (i) fractionation from raffinate-2, which is produced after
isobutylene has been extracted from raffinate-1; and (ii) production from
n-butylenes (predominantly butene-2) using the Company's patented SKIP process.

     After the removal of butene-1, the remaining n-butylenes stream (containing
principally butene-2 and n-butane) is either: (i) further purified to butene-2
which the Company sells intermittently based on customer demand; (ii) used as a
feedstock in the Company's SKIP process to produce butene-1 or isobutylene; or
(iii) used as a feedstock in the OXO-D process to produce crude butadiene. The
remaining product stream, containing principally n-butane, is sold to third
parties as a chemical by-product.

                                       36

SPECIALTY ISOBUTYLENE PRODUCTION PROCESSES

             [CHART SHOWING PRODUCTION OF HIGH PURITY ISOBUTYLENE,

                  ISOBUTYLENE CONCENTRATE AND DITOSOBUTYLENE]

     The Company takes advantage of its isobutylene production and extraction
capabilities to produce high purity isobutylene, isobutylene concentrate and
diisobutylene. The Company is currently the only U.S. producer of isobutylene
concentrate and diisobutylene and it is the largest of three U.S. producers of
high purity isobutylene.

     High purity isobutylene is manufactured by "back-cracking" a small
portion of the MTBE product stream into its components, isobutylene and
methanol. The isobutylene produced by this method is of extremely high purity
and the methanol is recycled and used in subsequent MTBE production. The Company
has an annual capacity to convert MTBE into 100 million pounds of high purity
isobutylene, and in the twelve months ended June 30, 1997, it sold 68 million
pounds principally on a contractual basis.

     The Company uses its patented dimerization process to produce diisobutylene
and has an annual production capacity of 50 million pounds. In the year ended
June 30, 1997 the Company sold 37 million pounds of diisobutylene principally on
a contractual basis.

     Some of the isobutylene produced by the Company is sold as concentrate. The
Company has an annual production capacity of 380 million pounds of isobutylene
concentrate and, in the year ended June 30, 1997, it sold 170 million pounds of
isobutylene concentrate. The Company has been successful in working with
customers to demonstrate the viability of concentrate as an alternative to high
purity isobutylene or lower purity raffinate-1 feedstock. The Company sells
isobutylene concentrate under contracts at prices linked to the cost of
isobutane feedstock and including energy costs and other components of
isobutylene concentrate, plus a fixed profit, as well as on the spot market.
While produced in smaller volumes than the Company's more commodity-type
products, specialty isobutylenes have historically had high margins due to the
niche sales markets for their end-use products.

OTHER OPERATIONS

     The Company operates a large scale cogeneration power plant that supplies
electricity and processes steam to the facility's chemical processing
operations. Excess capacity of this power plant, as well as steam and boiler
feed water are currently sold to neighboring facilities under contracts at a
price equal to the cost of fuel plus a fixed profit. In addition, the Company
generates revenues from its terminals in Baytown, Texas and Lake Charles,
Louisiana and from chemical by-product sales to third parties.

CONTRACTS

     The Company enters into three general types of contracts in connection with
its production processes: feedstock supply contracts, product sales contracts
and, to a lesser extent, toll manufacturing agreements. The majority of these
contracts have terms of two to three years and provide for successive one-year
renewals unless either party objects to such renewal in a timely manner. There
can be no assurance that

                                       37
<PAGE>
these agreements will remain in effect beyond their current terms or, if
extended, that the same provisions would continue to apply.

     FEEDSTOCK SUPPLY.  The Company typically purchases its principal feedstock,
crude butadiene, under contracts which require suppliers to deliver a percentage
(varying from 50% to 100%) of their total crude butadiene production. The price
of crude butadiene to the Company is typically based on the price of its
principal components: butadiene, n-butylenes, isobutylene and n-butane. The
price for the butadiene component of crude butadiene is generally set at the
Company's average selling price for butadiene less a fixed dollar amount, which
includes a variable component for energy costs. The prices for the n-butylene
and isobutylene components of crude butadiene are linked to spot gasoline prices
and the n-butane and isobutane components are linked to spot n-butane prices.

     The Company typically purchases methanol under contracts which require the
supplier to deliver minimum volumes of methanol. Methanol is generally purchased
at a discount to the prevailing market price, subject to specified minimum and
maximum price ranges.

     The majority of the Company's isobutane is purchased under contract from
EPC Venture, Inc. which provides 450,000 barrels per month. This supplier also
provides storage and pipeline transportation. Isobutane is purchased at the
prevailing average market price for each month.

     PRODUCT SALES.  The Company's sales contracts typically require customers
to purchase minimum volumes expressed either in absolute terms or as a
percentage of the customer's product needs. Pricing for butadiene is generally
set at a small discount to the recognized U.S. Gulf Coast contract market price,
while MTBE pricing is typically based on the average U.S. Gulf Coast spot market
price. Butene-1 is sold under contracts at prices based on formulae which links
the butene-1 selling price to the price of gasoline. Butene-1 is also sold on
the spot market at prevailing prices. Butene-2 is sold at negotiated market
prices. Pricing for isobutylene concentrate is generally linked to the cost of
its principal raw material, isobutane, and fuel plus a transportation fee and
other components, which are linked to relevant average spot market prices.
Pricing for high purity isobutylene and diisobutylene is typically based on
market prices.

     TOLL MANUFACTURING AGREEMENTS.  The Company toll processes crude butadiene
under contracts on behalf of third parties, including The Dow Chemical Company,
The Goodyear Tire & Rubber Company and Phillips 66 Company. Typically, the
Company returns butadiene to the customer and purchases the other butylenes and
butanes contained in the crude butadiene stream. The toll process fees allow the
Company to recover its energy production costs plus a fixed dollar amount. In
addition, the Company returns purified butene-1 to certain of its crude
butadiene suppliers under similar arrangements.

     OTHER.  The Company also provides storage and terminalling services under
contract to certain of its customers at its Baytown and Lake Charles facilities.

COMPETITION

     The petrochemical businesses in which the Company operates are highly
competitive. Many of the Company's competitors, particularly in the
petrochemical industry, are larger and have greater financial resources than the
Company. Among the Company's competitors are some of the world's largest
chemical companies and major integrated petroleum companies that have their own
raw material resources. In addition, a significant portion of the Company's
business is based upon widely available technology. Accordingly, barriers to
entry, apart from capital availability, may be low in the commodity product
section of the Company's business, and the entrance of new competitors into the
industry may reduce the Company's ability to capture improving profit margins in
circumstances where overcapacity in the industry is diminishing. Further,
petroleum-rich countries have recently become more significant participants in
the petrochemical industry and may continue to expand their role in this
industry in the future. Any of these developments would have a negative impact
on the Company's financial position, results of operations and cash flows.

     Given the nature of the markets in which it competes, the Company believes
it has two primary competitive advantages over its competitors. First, the
Company's position as the most significant merchant

                                       38
<PAGE>
crude butadiene processor in the U.S. has allowed it to secure supply
arrangements for crude butadiene, which provide for a fixed profit based on the
Company's selling prices for the finished product. The Company believes that
this partially limits its exposure to fluctuations in raw materials prices.
Secondly, the Company's flexible production processes enable it to take
advantage of increases in demand for its products at a lower cost than its
competitors, thus allowing the Company to meet its customers' needs through the
most economic processes.

     The Company's primary competitors in the sales of butadiene in the U.S. are
Exxon Chemical Company, Shell Chemical Company, Lyondell Petrochemical Company
and the Huntsman Group. With respect to MTBE, the Company competes primarily
with ARCO Chemical Company, Exxon Chemical Company, Valero Energy Corporation,
Texaco Inc. and Enron Corp. For sales of butene-1 the Company competes primarily
with Exxon Chemical Company, Chevron Chemical Company, Amoco Chemical Company,
Shell Chemical Company and Huls AG. For high purity isobutylene, the Company
competes in the U.S. with ARCO Chemical Company and Exxon Chemical Company.
Although the Company is the only North American producer of isobutylene
concentrate and diisobutylene, diisobutylene is also imported from Japan and
Europe.

SALES AND MARKETING

     The majority of the Company's sales are made pursuant to long-term sales
contracts with initial terms ranging from one to five years. The Company enjoys
long-standing relationships with its customers and approximately 85% of its
total sales over each of the last three years were made to the same customers.
The Company believes that its ability to maintain long-term customer contracts
has been facilitated by the extensive market knowledge and experience in the
petrochemical industry of its sales executives as well as the Company's emphasis
on customer relationships. The Company's strategy is to continue to increase
sales to existing customers and to attract new customers by providing
reliability of supply, competitive prices and superior customer service.

CUSTOMERS

     The Company's products are generally sold to major refining, chemical and
end-user corporations primarily located in the United States and Canada. The
Company believes that its butadiene customers place significant value on its
ability to provide a reliable domestic supply of butadiene due to its raw
material purchase contracts and its ability to produce butadiene through two
alternative methods. As a result, some of the largest and most established users
of butadiene in the industry have contracted to purchase butadiene from the
Company. Typically, the Company's butadiene sales contracts require these
customers to purchase a percentage of their total requirements from the Company
subject to a minimum volume. Pricing is based on prevailing market prices.

     The Company's principal butadiene customers include American Synthetic
Rubber Inc., The Dow Chemical Company, The Goodyear Tire & Rubber Company,
Enichem Elastomers Inc., E.I. du Pont de Nemours and Company and
Bridgestone/Firestone, Inc. In the year ended June 30, 1997, The Goodyear Tire &
Rubber Company accounted for approximately 11.4% of the Company's total
revenues.

     The Company's principal MTBE customers include Lyondell Petrochemical
Company, CITGO Petroleum Corporation and Mobil Oil Corporation. In the year
ended June 30, 1997, the Mobil Oil Corporation accounted for approximately 16.7%
of the Company's total revenues.

     The Company's principal butene-1 customers include Union Carbide
Corporation, Shell Chemical Company, Lyondell Petrochemical Company, NOVA
Chemicals Ltd. and The Dow Chemical Company. The Company's principal butene-2
customers include Shell Chemical Company.

     The Company's principal specialty isobutylene customers include Bayer Inc.,
The Lubrizol Corporation, Schenectady International, Inc., Rhone-Poulenc Inc.
and Mobil Chemical Company Inc.

PATENTS AND LICENSES

     The Company presently owns, controls or holds rights to approximately 21
patents. The Company believes that its patents, particularly its patents
relating to the SKIP, OXO-D and diisobutylene production processes, are
important to its business and provide the Company with certain competitive
advantages.

                                       39
<PAGE>
Accordingly, the Company actively protects existing production process
technologies. The Company's patents relating to (i) the SKIP production
processes expire September 21, 2002, and August 27, 2008; (ii) the OXO-D

ENVIRONMENTAL REGULATION

     The Company's policy is to be in compliance with all applicable
environmental laws. The Company is also committed to Responsible CareT, a
chemical industry initiative to enhance the industry's responsible management of
chemicals. The Company's operations are subject to federal, state, and local
laws and regulations administered by the EPA, the U.S. Coast Guard, the Army
Corps of Engineers, the TNRCC, the Texas General Land Office, the Texas
Department of Health and various local regulatory agencies. The Company holds
all required permits and registrations necessary to comply substantially with
all applicable environmental laws and regulations, including permits and
registrations for wastewater discharges, solid and hazardous waste disposal and
air emissions, and management believes that the Company is in substantial
compliance with all such laws and regulations. While management does not expect
that compliance with existing environmental laws will have a material adverse
effect on the Company's financial condition or results of operations, there can
be no assurance that future legislation, regulation or judicial or
administrative decisions will not have such an effect.

     Under federal and state environmental laws, companies may be liable for
remediation of contamination at on-site and off-site waste management and
disposal areas. Management believes that the Company is not likely to be
required to incur remediation costs related to its management, transportation
and disposal of solid and hazardous materials and wastes, or to its pipeline
operations. If the Company were to be required to incur such costs, however,
management believes that such costs would not have a material adverse effect on
the Company's results of operations. In addition, under the terms of the 1984
purchase agreement, the prior owner of the Houston facility, Petro-Tex, has
indemnified the Company for liability arising from off-site disposal of any
materials prior to June 1984. Notwithstanding the terms of the indemnity, in
July 1994 Petro-Tex filed a claim for indemnity against the Company for any
costs that may be attributable to Petro-Tex for the cleanup of the Malone
Service Company ("Malone") site in Texas City, Texas. Petro-Tex and many other
companies along the Gulf Coast allegedly sent wastes to the Malone site for
disposal in the 1970s and possibly the early 1980s. Malone has been subject to
several state enforcement actions regarding its waste disposal practices, and
TNRCC has revoked Malone's permits to operate its facilities. It is not known
whether the site will require remediation or at what cost. The Company believes
that it has meritorious defenses to Petro-Tex's claim and intends to contest the
claim vigorously. Although no on-site contamination has been identified as
requiring remediation, management believes that certain areas of the Houston
facility were historically used for waste disposal. Based on limited, currently
available information about these waste disposal areas and their contents, the
Company believes that, if such remediation becomes necessary, any remediation
costs would not have a material adverse effect on the Company's financial
condition or results of operations. The Petro-Tex indemnity does not extend to
these on-site waste disposal areas or their contents.

     The day-to-day operations of the Company are subject to extensive
regulation under the Resource Conservation and Recovery Act, the Federal Clean
Water Act, the CAAA and similar requirements of state law. In particular, under
the CAAA, the EPA and TNRCC have promulgated, or are required to promulgate,
numerous regulations which affect or will affect the operations of the Company.
The most significant of these are the so-called Hazardous Organics National
Emission Standard for Hazardous Air Pollutants or HON Rule, the requirements of
Title V of the CAAA and rules relating to the controls of oxides of nitrogen,
which are known as the Nitrogen Oxides Reasonably Available Control Technology
rules ("NOx RACT Rules").

                                       40
<PAGE>
     The HON Rule requires additional controls on emissions of certain listed
hazardous air pollutants ("HAPs"). Butadiene, methanol, dimethyl formamide and
MTBE, which are manufactured, used and/or processed by the Company, have been
identified as HAPs for purposes of regulation under the CAAA. Areas of concern
in the Company's operations for HAPs emissions include equipment leaks, process
vents, product storage, transfer operations and emissions from wastewater
streams. The Company has examined each of these areas and believes that it is in
substantial compliance with the HON Rule.

     The NOx RACT Rules require compliance by May 1999. The Company has examined
the rules and believes that the main expenditure required to achieve compliance
will involve purchase and installation of monitoring equipment for NOx
emissions, which can be either continuous emission monitors, predictive emission
monitors or other approved monitoring methods. Based on its preliminary study,
management estimates that the cost to comply with the NOx RACT Rules will be $2
million over the next three years.

     The Company's Houston facility is located in Harris County, Texas, which
has been designated as a non-attainment area for ozone under the CAAA.
Accordingly, the State of Texas has developed a State Implementation Plan
("SIP") which requires reductions in emissions of ozone precursors, including
volatile organic compounds and NOx, as well as carbon monoxide, in Harris
County. To comply with the SIP, the Company installed new controls at a cost of
approximately $7.8 million. The Company anticipates that, at some time in the
future, the State of Texas may promulgate rules which will require the Company
to modify existing controls or to install additional controls for fugitive air
emissions. The Company estimates that, if these rules are promulgated, it will
incur costs of between $1 million and $2 million in order to modify or install
such controls over a five- or six-year period.

     EPA has recently finalized more stringent standards for ozone and
particulate matter. Moreover, the Texas Legislature recently passed legislation
directing TNRCC to develop a plan to address the permitting of so-called
"grandfathered" emissions sources which are unpermitted sources constructed
prior to promulgation of permitting regulations. Because implementing
regulations for these standards have not yet been proposed, the Company cannot
predict whether their impact on the Company's operations will be material.

     Title III of the CAAA requires prevention of accidental releases of certain
listed extremely hazardous substances. The EPA's rules implementing portions of
Title III, promulgated on June 20, 1996, will require the Company to conduct a
hazards assessment and develop a risk management plan by June 1999 for each
extremely hazardous substance that the facility manufactures, uses, generates or
processes.

     The regulations under Title V of the CAAA, which will require a
facility-wide inventory of emissions sources at the Houston facility and a
single operating permit for the facility's air emissions, have not been
promulgated. Based on a preliminary review of the draft requirements, however,
the Company believes that it will have to undertake substantial efforts to
conduct an emissions source inventory. It may also be required to upgrade its
on-going monitoring program once it has received its operating permit; however,
the Company does not expect any costs associated therewith to be significant. It
is also possible that the Company may be required to make modifications to some
of its equipment in order to comply with the terms of the facility-wide permit.

     The Company has an active program to manage asbestos-containing material at
its Houston facility in accordance with federal and state environmental, health
and safety regulations. The Company does not believe that these materials pose a
hazard to the health of its employees. There is no requirement to remove these
materials, provided they are properly managed. As the plant is reconfigured or
additions are made, asbestos-containing materials are removed or encapsulated by
a certified contractor.

     The wastewater treatment system for the Houston facility is 75% owned by
the Company and 25% owned by Bayer Corporation ("Bayer"), the owner of an
adjacent facility. Bayer operates the treatment system, but the federal and
state discharge permits are held jointly by the Company and Bayer. The Company
believes that the system has sufficient capacity for the Company's projected
needs.

     In February 1996, the EPA issued an order to the Company and Bayer
requiring the companies to resolve the exceedances of their discharge permit
limits for copper and total suspended solids that had occurred since 1992. The
Company believes that these issues have been resolved by raising the limits in
the new discharge permit and by other corrective actions. No penalties were
assessed.

                                       41
<PAGE>
     To meet rules expected to be promulgated concerning stormwater runoff, the
Company has budgeted to spend approximately $500,000 by 2000 for additional
stormwater control and collection. The Company has also budgeted $600,000
through fiscal 1999 to purchase noise barriers for certain equipment.

     The terminals in Baytown and Lake Charles are in substantial compliance
with applicable environmental laws and regulations, and management believes that
no significant expenditures will be required at these facilities to allow them
to continue to comply with such laws and regulations.
   
     MTBE and butadiene are the subject of continuing health effects studies.
While there have been some questions about the health effects of MTBE, a
multi-agency review, released June 30, 1997 by the White House's Office of
Science and Technology Policy ("OSTP"), concluded that health studies have
shown that "persons are not at increased risk of experiencing acute health
effects due to the use of fuels blended with oxygenates like MTBE." In
addition, a study by the Health Effects Institute, commissioned by the EPA and
the Centers for Disease Control and Prevention, reported that adding oxygenates,
including MTBE, to gasoline reduces emissions of carbon monoxide and benzene and
is unlikely to increase substantially the health risks associated with fuel used
in motor vehicles. While the EPA, California and other states are expected to
adopt limits for MTBE levels in drinking water, these limits are not expected to
be overly restrictive since that same OSTP report concluded that drinking water
is "not a major route of exposure" for MTBE. Recently there have been
legislative initiatives to eliminate the use of MTBE as a fuel additive in
certain geographic areas. To date such initiatives have not been successful. The
Company cannot predict whether such legislation will be reintroduced, or if it
would be enacted if reintroduced; however, the elimination of MTBE as a fuel
additive in major markets could have a material adverse effect on the Company.
The EPA has also determined that butadiene is a probable human carcinogen.
Effective February 1997, the Occupational Safety and Health Administration
lowered the employee permissible exposure limit ("PEL") over an 8-hour
time-weighted average for butadiene from 1000 parts per million ("ppm") to 1
ppm. The Company has conducted employee exposure monitoring and believes that it
already meets the PEL at most of its operations. For some operations, the
Company anticipates that affected employees will need to use respirators and
that additional emissions controls may be necessary. The Company does not
expect, however, that the current health concerns regarding butadiene will have
a material adverse effect on the Company's financial condition or results of
operations, although no assurances can be given that future studies will not
result in more stringent regulation of butadiene.
    
EMPLOYEES

     As of June 30, 1997, the Company had approximately 319 full-time employees,
all of whom were salaried employees. In addition, the Company contracts with a
third party to provide approximately 145 contract employees to perform routine
maintenance on and around its Houston facility. The Company believes its
relationship with its employees is satisfactory.

SAFETY RECORD

     The Company maintains one of the best workman's compensation records in
Texas, equivalent to most clerical operations. Over the last seven years, the
Company has experienced only three lost time injuries. The Company believes this
record is accomplished through extensive classroom and on-the-job training as
well as the efforts of its highly trained, 67-member volunteer emergency
response team.

PROPERTIES

     The Company's plant is located on a 257-acre tract approximately one mile
from the Houston Ship Channel and near one of the chemical industry's largest
domestic processing facilities. Approximately 230 acres is owned by the Company,
and 25% of the remaining 27 acres is owned by Bayer. The Company leases from the
Port of Houston two ship docks which accommodate barge and ocean-going vessels,
and has the facilities to be served by rail and by truck. In addition, the
facility is connected by pipeline to customers and suppliers of raw materials,
directly and through other major pipelines in the immediate area as well as in
Texas City, and with salt dome storage facilities of other companies located at
both Mont Belvieu and Pierce Junction, Texas. The Company's facility also has a
laboratory for sampling and testing. The Company owns and operates a storage and
terminal facility at Baytown, Texas, leases a storage and terminal facility in
Lake Charles, Louisiana and Linden, New Jersey, and leases tank storage capacity
in

                                       42
<PAGE>
Bayonne, New Jersey. The Company also leases office space in Three Riverway
Plaza, Houston, Texas as its principal executive offices. The Company believes
that is has adequate facilities for the conduct of its current and planned
operations.

LEGAL PROCEEDINGS

     In addition to the matters disclosed under "-- Environmental Regulation,"
the Company is a party to various claims and litigation arising in the ordinary
course of its business. Management recognizes the uncertainties of litigation
and the possibility that one or more adverse rulings could materially impact
operating results. However, although no assurances can be given, management
believes that other than as disclosed, based on the nature of and its
understanding of the facts and circumstances which give rise to such claims and
litigation, and after considering appropriate reserves that have been
established, that the ultimate resolution of such issues, individually and in
the aggregate, will not have a material adverse effect on the Company's
statements.

(2) Includes 401(k) contributions in 1996 and 1995 of $21,035 and $24,618,
    respectively, for Mr. Manning and $21,149 and $24,440, respectively, for Mr.
    McNeese.

EMPLOYMENT AND OTHER AGREEMENTS

     In 1992, Mr. Waycaster entered into an employment agreement with TOC and
TPC which provided for an annual base salary of $300,000 and a minimum annual
cash bonus of $300,000. The agreement expired on April 1, 1997. Mr. Waycaster
remains employed with the Company without an employment agreement. In addition,
Mr. Waycaster has entered into a non-competition agreement with TOC and TPC
covering the three-year period following the last date he receives compensation
from the Company.

     In connection with his employment, Mr. Waycaster also received a grant of
options to purchase up to 50,000 shares of TPC common stock at a purchase price
of $40 per share. The options were cancelled in connection with the Acquisition.

     In 1994, TPC entered into an agreement with each of Mr. Shelton, a director
of the Company, and Mr. Woliver which provides a benefit in the event of death
while an employee of TPC. Provided the individual is survived by his wife, the
death benefit continues monthly for the shorter of the life of the wife (or in
the case of Mr. Woliver, so long as he also has minor children) or 60 months,
and is $10,000 per month with respect to Mr. Shelton and $10,000 per month with
respect to Mr. Woliver. Each agreement terminates on termination of employment
for any reason other than death or disability of the individual.

EMPLOYEE STOCK OWNERSHIP PLAN

     In connection with the Acquisition, Finance Co. established an Employee
Stock Ownership Plan (the "ESOP"), covering substantially all full-time
employees, including executive officers, of the Company who satisfy the
requirements described below. The ESOP, which invests primarily in shares of
Common Stock, borrowed $10.0 million from Finance Co. pursuant to a loan (the
"Company ESOP Loan") to

                                       46
<PAGE>
purchase 100,000 shares of Common Stock. Finance Co. funded the Company ESOP
Loan from the ESOP Term Loan. The Company ESOP Loan matures on June 30, 2001,
and bears interest at interest rates based on the Alternative Base Rate (as
defined) or the LIBOR Rate (as defined). The outstanding principal of the
Company ESOP Loan is payable in twenty equal quarterly installments of $500,000
during the period beginning September 30, 1996 and ending June 30, 2001. The
shares of Common Stock purchased by the ESOP were pledged (the "ESOP Pledge")
as security for the Company ESOP Loan, and such shares will be released and
allocated to ESOP participants' accounts as the Company ESOP Loan is discharged.
The Company may make contributions to the ESOP as determined by the Board of
Directors in an amount anticipated to be equal to a certain percentage of the
total annual earnings of all ESOP participants (the "Discretionary
Contributions"). The Company intends to make Discretionary Contributions in
amounts sufficient to enable the ESOP to discharge its indebtedness under the
Company ESOP Loan; however, the Company has no legal obligation to make
Discretionary Contributions. Shares released under the ESOP Pledge are allocated
to each participant based on such participant's base compensation relative to
total base compensation for all ESOP participants. Until the Company ESOP Loan
is paid in full, Discretionary Contributions will be used to pay the outstanding
principal and interest on the Company ESOP Loan. For employees whose employment
commenced prior to October 1, 1996 and who have attained the age of 21 years,
participation begins as of the later to occur of July 1, 1996 or the date of
commencement of the participant's employment. A participant's ESOP account vests
at the rate of 20% per year. Distributions from the ESOP are made in cash or
Common Stock upon a participant's retirement, death, disability or termination
of employment. In the event of retirement, death or disability, the entire
balance of a participant's ESOP account will become distributable without regard
to the ordinary vesting schedule. In the event of termination of employment for
any other reason, the vested portion of a participant's ESOP account will become
distributable and the remaining portion, if any, will be forfeited. If Common
Stock is distributed to a participant, the participant may, within two 60-day
periods, require the Company to purchase all or a portion of such Common Stock
at the fair market value of the Common Stock as determined under the ESOP (the
"Put Options"). The first 60-day period commences on the date the participant
receives a distribution of Common Stock and the second 60-day period commences a
year from such date. If a participant fails to exercise either of the two Put
Options, the participant may transfer the shares of Common Stock only upon
receipt of a bona fide third party offer and only after first offering the
shares to the ESOP and then to the Company. Employees of the Company own
approximately 20% of the outstanding Common Stock through the ESOP after the
Acquisition.

PROFIT SHARING PLAN

     Prior to the date of the Acquisition, TPC maintained a Profit Sharing Plan
(the "Profit Sharing Plan") covering substantially all of its employees,
including executive officers. The Profit Sharing Plan is designed to qualify
under Section 401(k) of the Internal Revenue Code of 1986, as amended (the
"Internal Revenue Code"). Each participant has the option to defer taxation of
a portion of such participant's earnings by directing TPC to contribute a
percentage of such earnings to the Profit Sharing Plan. A participant may direct
a minimum of 1% and a maximum of 10% of eligible earnings to the Profit Sharing
Plan, subject to certain limitations set forth in the Internal Revenue Code. TPC
currently makes a matching contribution monthly equal to 25% of the amount of
compensation deferred by each participant in such month, up to 6% of the
participant's base compensation for such month. TPC may also make a
discretionary contribution to the Profit Sharing Plan. Participants' Profit
Sharing Plan accounts become distributable at retirement, upon disability, death
or termination of employment, or under certain circumstances, upon attainment of
age 59. Participants are fully vested at all times in all amounts deferred by
them to the Profit Sharing Plan, and they become vested in the Company's
matching and discretionary contributions under a five-year graded vesting
schedule.

     TPC is continuing the Profit Sharing Plan in substantially the same form as
TPC maintained such plan prior to the Acquisition, provided that the
discretionary contribution will be made only if certain levels of earnings
before interest, taxes, depreciation and amortization are satisfied by the
Company in accordance with the Nonqualified Profit Sharing Incentive Plan (as
described below).

                                       47
<PAGE>
CASH BONUS PLAN

     Prior to the date of the Acquisition, TPC established the Cash Bonus Plan
covering substantially all employees of TPC (or certain affiliates of TPC) and
covering the employees of certain third-party contractors who have contributed
to the success of TPC (or certain affiliates thereof). Upon the occurrence of a
Change of Control (as defined below), an employee participant as of July 2, 1996
will be distributed a portion of $3,200,000 within forty-five days of the date
of the Change of Control and will be distributed a portion of $1,800,000 plus
interest in each of sixteen quarterly installments following the date of the
Change of Control so long as the employee is an employee of TPC (or certain
successors or affiliates of TPC) on the corresponding quarterly installment
date. Upon the occurrence of a Change of Control, an eligible employee of a
third-party contractor who is providing services to TPC (or certain successors
or affiliates thereof) on July 2, 1996 will be distributed a portion of $300,000
within forty-five days of the date of the Change of Control, and will be
distributed a portion of $168,750 plus interest in each of sixteen quarterly
installments following the date of the Change of Control so long as the employee
of the third-party contractor is providing services to TPC on the corresponding
quarterly installment date. Each participant's allocable share of the bonus
payments to be made under the Cash Bonus Plan is based on a formula which
considers a participant's compensation and length of service with TPC. If a
participant retires, dies, becomes disabled, or whose employment is terminated
without cause after July 2, 1996, such participant's beneficiary or
representative will continue to receive a portion of the bonus payments through
the sixteenth installment payment even though such participant is no longer
employed by TPC or the third-party contractor which is providing services to
TPC. Under the Cash Bonus Plan, a "Change of Control" is deemed to occur when
the outstanding stock of TOC is acquired, or more than 50% of the shares of
TPC's common stock is sold, in a cash tender offer, exchange offer, merger,
third-party private purchase or other means of acquisition, or when
substantially all of the assets of TPC are sold to an unrelated third party. The
Acquisition effected a Change of Control and distributions from the Cash Bonus
Plan have commenced.

STOCK OPTION PLAN

     Holdings has established a stock option plan (the "Option Plan"). The
Option Plan is administered by a committee (the "Committee") of the Board of
Directors of Holdings. Option grants under the Option Plan will be permitted to
be made to directors and key employees of Holdings and its subsidiaries,
including the Company, selected by the Committee. The Committee may grant
"incentive stock options" within the meaning of Section 422 of the Internal
Revenue Code and also will be permitted to grant "nonstatutory options," which
are not intended to conform to Section 422 of the Internal Revenue Code. The
Option Plan will provide for the discretionary grant of options to purchase
shares of Common Stock. The exercise price of incentive stock options shall not
be less than the fair market value of a share of Common Stock on the date of
grant, and the exercise price of nonstatutory options shall not be less than 85%
of the fair market value of a share of Common Stock on the date of grant. The
Committee will be permitted to provide that the options will vest immediately or
in increments. No option will be transferable by a grantee other than upon
death. On the termination of employment or disability of any grantee, any
unvested options will either expire or continue to be exercisable as determined
by the Committee, in its sole discretion. The Option Plan will terminate no
later than 10 years after its adoption; however, any options outstanding upon
termination of the Option Plan will remain in effect until exercised or
terminated pursuant to the terms of the agreement under which they were granted.
A participant in the Option Plan may, upon receiving approval from the
Committee, relinquish all or a portion of such participant's options for an
amount in cash equal to the difference between the fair market value of the
Common Stock corresponding to the options being relinquished on the day of
relinquishment, less the total option price for such corresponding shares.

(1)  The options reported in this column consist of Non-Qualified Options
     granted under Option Agreements between the Company and each of the Named
     Executive Officers. The options will become exercisable on each of the
     first, second and third anniversaries of the date of grant with respect to
     one-third of the shares subject to the option.

(2)  Based on outstanding options to purchase an aggregate of 27,778 shares of
     Common Stock.

(3)  The dollar amounts under these columns are the result of calculations at
     the 5% and 10% appreciation rates set by the Commission and, therefore, are
     not intended to forecast possible future appreciation, if any, in the price
     of the Common Stock. In order to realize the potential values set forth in
     the 5% and 10% columns of this table, the per share price of the Common
     Stock would be $163 and $259, respectively, or 63% and 159% respectively,
     above the base exercise price. Because the Common Stock is not currently
     publicly traded, these amounts were calculated based on the assumption that
     the fair market value of one share of Common Stock on the date of grant was
     equal to the exercise price.

Common Stock held as of June 30, 1997, by the Named Executive Officers.

NONQUALIFIED PROFIT SHARING INCENTIVE PLAN

     The Company has established two separate Nonqualified Profit Sharing
Incentive Plans, both of which will be administered by the Committee. Amounts
paid to employees in cash under the Nonqualified Profit Sharing Incentive Plans
will constitute taxable income in the year received and will be based on the
Company's financial performance for the period commencing on the first day of
the Company's fiscal year and ending on the last day of each fiscal quarter
during such year. One of the Nonqualified Profit Sharing Incentive Plans is only
for officers of the Company who are selected by the Committee (the "Officers'
Plan"). If the Company's EBITDA exceeds certain prescribed levels, the officers
participating in the Officers' Plan will receive distributions in cash from the
Company equal to a certain percentage of EBITDA recommended by the Chief
Executive Officer of the Company and approved by the Committee. Under the other
Nonqualified Profit Sharing Incentive Plan which is for all employees not
participating in the Officers' Plan, if EBITDA exceeds certain prescribed
levels, a percentage of EBITDA will be used: first, to satisfy any required
contributions to the ESOP; second, to satisfy any required matching
contributions to the

                                       49
<PAGE>
Profit Sharing Plan; third, to contribute annually to the Profit Sharing Plan
for the benefit of its participants up to the maximum amount allowable under the
Internal Revenue Code for qualification and deduction purposes; fourth, to
distribute cash to employees in an amount equal to $1.00 multiplied by the
number of base hours an employee worked during a fiscal quarter (up to a maximum
of 520 hours); and fifth, to distribute any remaining excess in cash to
employees based on their base compensation for such period. The Nonqualified
Profit Sharing Incentive Plans will not be qualified under Section 401(a) of the
Internal Revenue Code.

                          THE SELLING SECURITY HOLDER

     The Discount Notes are offered for the account of the Huff Fund. The Huff
Fund owns 10.9% of the Common Stock of Holdings. The Huff Fund is a party to a
Voting Agreement with certain other stockholders of Holdings which results in
the Huff Fund controlling one seat on the Board of Directors of the Company. See
"Related Transactions." Mr. William R. Huff is a Director of the Company, as
the designee of the Huff Fund. Mr. Huff is also President of the General Manager
of WRH Partners, L.L.C., the General Partner of the Huff Fund. See
"Management." The Huff Fund is the holder of the entire principal amount of
the Discount Notes. The Huff Fund will sell the Discount Notes for its own
account from time to time pursuant to this Prospectus as it deems appropriate.

                              RELATED TRANSACTIONS

     TPC historically engaged in certain raw material purchase transactions with
Clarkston, which prior to the consummation of the Acquisition was owned by
several of the same individuals who were stockholders of TOC and/or TPC. In the
twelve months ended May 31, 1996, TPC made purchases of raw materials from
Clarkston of approximately $113.4 million. As part of the Acquisition, TPC
assumed from Clarkston a contract between Clarkston and a certain supplier for
the purchase of isobutane. In connection with the Acquisition, Clarkston was
dissolved and 80% of the outstanding capital stock owned by TOC of The Texas
Falls Corporation was sold to a prior stockholder of TOC and/or TPC. Messrs.
Shelton, Woliver, Waycaster and a prior stockholder of TOC and/or TPC
collectively own the remaining 20% of the outstanding capital stock of The Texas
Falls Corporation.

     Sterling entered into an agreement with Holdings and TPC Holding pursuant
to which Sterling provided consulting and advisory services with respect to the
organization of Holdings, TPC Holding and Finance Co., the structuring of the
transactions associated with the Acquisition, employee benefit and compensation
arrangements and other matters. The agreement also provides that Holdings and
TPC Holding, jointly and severally, indemnify Sterling against liabilities
relating to its services. TPC paid Sterling a one-time transaction fee of
approximately $4.0 million for these services, and reimbursed Sterling for its
expenses. In addition, each of Holdings, TPC Holding and TPC has agreed that if
it or any of its subsidiaries determines within two years of the date of the
agreement to dispose of or acquire any assets or business, to offer its
securities for sale or to raise any debt or equity, either Holdings, TPC
Holding, TPC or the relevant subsidiary will retain Sterling as a consultant
with respect to the transaction, provided that Sterling's fees are on terms no
less favorable to Holdings, TPC Holding, TPC or the relevant subsidiary than
would be available from unaffiliated third parties.

     Holdings, TPC Holding and Finance Co. were organized by Sterling for the
purpose of effecting the Acquisition. Ms. Susan Rheney, a principal of Sterling,
and Mr. Gordon A. Cain, are directors of Holdings, TPC Holding and TPC. See
"Management." Mr. Cain and Ms. Rheney purchased 76,150 and 5,000 shares of
Common Stock, respectively, in connection with the Acquisition at a price of
$100 per share, the same price at which all shares were sold in connection with
the Acquisition.

     As a matter of policy, the agreement between the Company and Sterling is,
and all future transactions between the Company and its respective directors,
officers and affiliates will be, on terms no less favorable to the Company than
those available from unaffiliated third parties.

     Certain stockholders of Holdings, representing a majority of the
outstanding capital stock of Holdings entitled to vote for the election of
directors of Holdings, have entered into a Voting Agreement with Holdings
pursuant to which they have agreed to vote for a designee nominated by the Huff
Fund and a designee nominated by Chase Venture for election to the Board of
Directors of Holdings. As a result of the Voting Agreement, each of the Huff
Fund and Chase Venture have the right to control one seat on the Board of
Directors of the Company.

     Chase Securities, an affiliate of Chase Venture, acted as the Initial
Purchaser of the Notes, receiving customary fees.

     See "-- Employment and Other Agreements" for a description of Mr.
Waycaster's employment agreement.

                    DESCRIPTION OF THE BANK CREDIT AGREEMENT

GENERAL

     Finance Co. and TPC entered into the Bank Credit Agreement (the "Bank
Credit Agreement") with a syndicate of lenders (the "Lenders"), and Texas
Commerce Bank National Association, as Agent for such Lenders (the "Agent")
and effected the initial borrowings described below on July 1, 1996. The
following description summarizes the material provisions of the Bank Credit
Agreement, but such description does not purport to be complete and is subject
to, and is qualified in its entirety by reference to, the provisions of the Bank
Credit Agreement, a copy of which is filed as an exhibit to the Registration
Statement. All capitalized terms in this "Description of the Bank Credit
Agreement" section not defined in this Prospectus have the meanings assigned
thereto in the Bank Credit Agreement. Holdings has guaranteed the obligations of
TPC under the Bank Credit Agreement.

     The Bank Credit Agreement provides for secured facilities consisting of (i)
a six and one-half year revolving credit facility providing for up to $40.0
million in revolving loans, a specified portion of which was used for letters of
credit (the "Revolving Credit Facility") and (ii) a term loan facility
providing for $140.0 million in term loans consisting of (x) a six and one-half
year term loan of $85.0 million (the "Tranche A Term Loan"), (y) an eight-year
term loan of $45.0 million (the "Tranche B Term Loan," and, together with the
Tranche A Term Loan, the "Senior Term Loans") and (z) a five-year term loan of
$10.0 million (the "ESOP Term Loan," and, together with the Senior Term Loans,
the "Term Loans").

     The Revolving Credit Facility permits, at the option of TPC, the issuance
of letters of credit in principal amounts to be determined thereunder. Loans and
letters of credit under the Revolving Credit Facility are subject to a borrowing
base consisting of 85% of Eligible Accounts and 65% of Eligible Inventory
(collectively, the "Borrowing Base"), provided that at no time shall more than
50% of the Borrowing Base be comprised of 65% of Eligible Inventory.

AMORTIZATION; PREPAYMENTS

     The Bank Credit Agreement requires the principal amount of the Senior Term
Loans to be reduced in twelve quarterly principal installments of $2.75 million
beginning on September 30, 1996, four quarterly principal installments of $3.25
million beginning on September 30, 1999, four quarterly principal installments
of $4.0 million beginning on September 30, 2000, four quarterly principal
installments of $4.75 million beginning on September 30, 2001, four quarterly
principal installments of $6.0 million beginning on September 30, 2002, and four
quarterly principal installments of $6.25 million beginning on September 30,
2003. The ESOP Term Loan will be amortized in 20 equal quarterly installment
amounts of $0.5 million during its five-year term.

     The Senior Term Loans are subject to mandatory prepayment prior to
September 30 of each fiscal year (commencing in fiscal 1997) in which more than
$75.0 million is outstanding on the Senior Term Loans on or before June 30 of
any year, of an amount equal to 75% of the difference between EBITDA (as
defined) for the prior fiscal year and the sum of certain capital expenditures,
taxes, dividends, interest expense, and principal payments made on the Senior
Term Loans during such prior year, and certain distributions made to TPC Holding
for certain expenses (such difference being the "Excess Cash Flow"), and prior
to September 30 of each year after the Senior Term Loans are reduced to $75.0
million or less, a payment in the amount of 50% of the Excess Cash Flow
generated during the prior fiscal year. All mandatory prepayments are required
to be applied pro rata to each Senior Term Loan based on the outstanding
principal amount of the Senior Terms Loans and pro rata to future scheduled
principal installments. In addition, the Senior Term Loans are further subject
to mandatory prepayment in the amount of any cash proceeds received by the
Company from an offering of its Capital Stock.

     The Senior Term Loans may be prepaid on notice at any time without premium
or penalty in a minimum amount of $1.0 million. All optional prepayments of the
Term Loans will be applied pro rata to each Senior Term Loan based on the
outstanding principal amount of the Senior Term Loans unless, at the Company's
option, lenders of the Tranche B Term Loan decline to accept such prepayment, in
which case the amount of prepayment declined shall be applied pro rata to the
Tranche A Term Loan and will be applied pro rata to future scheduled principal
installments.

                                       53
<PAGE>
     The amount available under the Revolving Credit Facility is payable in full
on its maturity date. Additionally, if the aggregate amount of borrowings
outstanding under the Revolving Credit Facility, plus the undrawn face amount of
letters of credit plus unreimbursed drawings on letters of credit, exceeds the
Borrowing Base, an immediate prepayment in an amount to eliminate such excess
will be payable.

     Prepayments of Eurodollar borrowings on any day other than the last day of
an interest period will be required to be accompanied by a payment to the
Lenders of all costs, expenses or losses, if any, incurred as a result of such
prepayment.

SECURITY; GUARANTEES

     Borrowings under the Revolving Credit Facility and the Term Loans are
guaranteed by Holdings and TPC Holding. The obligations of TPC under the
Revolving Credit Facility and the Term Loans and the obligations under the
guarantees are secured by a first priority lien on the capital stock of TPC
Holding and TPC and on substantially all of the assets of TPC.

INTEREST RATES; LETTER OF CREDIT FEES

     The Term Loans and the Revolving Credit Facility bear interest at a rate
per annum, at TPC's option, within the range of either (i) the Alternate Base
Rate to the Alternate Base Rate plus 1.5% or (ii) the LIBOR Rate plus .625% to
the LIBOR Rate plus 2.5%, in each case based upon the ratio of Total Debt (as
defined) to EBITDA for the most recent four-quarter period.

     Under the Revolving Credit Facility, fees will be charged for letters of
credit as follows: (i) a fronting fee of 1/8% per annum on the undrawn face
amount of the letters of credit plus (ii) the greater of (x) for each letter of
credit outstanding, the applicable margin for LIBOR Rate Loans, and (y) $500.

FEES, EXPENSES AND COSTS; REVOLVING CREDIT FACILITIES

     The terms of the Bank Credit Agreement require the Company to pay the
following fees in connection with the maintenance of borrowings under the
Revolving Credit Facility: (i) commitment fees to be paid to the Lenders in
amounts equal to 1/2% per annum, if the Company's ratio of Total Debt to EBITDA
for the most recent four-quarter period is greater than or equal to 3.0 to 1.0,
and 3/8% if the Company's ratio of Total Debt to EBITDA for the most recent
four-quarter period is less than 3.0 to 1.0, in each case with respect to the
unused commitment under the Revolving Credit Facility payable quarterly in
arrears until such time as it is terminated; and (ii) administration fees
payable annually to the Agent. In addition, the Company paid various
underwriting and arrangement fees and closing costs on July 1, 1996 in
connection with the origination and syndication of the Term Loans and the
Revolving Credit Facility.

     The Company also is required to reimburse the Agent for all reasonable
out-of-pocket costs and expenses incurred in the preparation, documentation,
syndication and administration of the Bank Credit Agreement and to reimburse the
Lenders for all reasonable costs and expenses incurred in connection with the
enforcement of their rights in connection with a default or the enforcement of
the Bank Credit Agreement. The Company agreed to indemnify the Agent and the
Lenders and their respective officers, directors, shareholders, employees,
agents and attorneys against certain costs, expenses (including fees and
disbursements of counsel) and liabilities arising out of or relating to the Bank
Credit Agreement, the Stock Purchase Agreement and the transactions contemplated
thereby. Furthermore, the Lenders are entitled to be reimbursed for increases in
reserve requirements, changes in law and circumstances, possible future
illegality of interest options, taxes (other than on gross receipts or income),
possible inability to determine market rate, capital adequacy, and consequential
costs.

                       DESCRIPTION OF THE DISCOUNT NOTES

GENERAL

     The Discount Notes were issued under an Indenture dated as of July 1, 1996
(the "Discount Notes Indenture"), between the Company and Fleet National Bank,
as Trustee (the "Trustee").

     The following is a summary of the material provisions of the Discount Notes
Indenture and the Discount Notes. Upon effectiveness of the Registration
Statement, the Discount Notes Indenture will be subject to the Trust Indenture
Act of 1939, as amended (the "Trust Indenture Act"). The following summary of
certain provisions of the Discount Notes Indenture and the Discount Notes (i) is
a description of such provisions after giving effect to the consummation of the
transactions associated with the Acquisition, and (ii) does not purport to be
complete and is subject to, and is qualified in its entirety by reference to,
all the provisions of the Discount Notes Indenture and the Discount Notes,
including the definitions of certain terms therein and those terms made a part
thereof by the Trust IndentureAct. The Discount Notes Indenture is filed as an
exhibit to the Registration Statement of which this Prospectus is a part. Any
reference to a "Holder" or a "Noteholder" or a "Securityholder" means the
Holders of the Discount Notes.

     Principal of, premium, if any, and interest on the Discount Notes are
payable, and the Discount Notes may be exchanged or transferred, at the office
or agency of the Company in the Borough of Manhattan, The City of New York or
the State of Connecticut (which initially shall be the offices of the Trustee,
at Shawmut Trust Company of New York, c/o First Chicago Trust Co. of N.Y., 14
Wall Street, 8th Floor / Window #2, New York, New York 10005 or at 777 Main
Street, Hartford, Connecticut 06115, respectively), except that, at the option
of Holdings, payment of interest may be made by check mailed to the address of
the Holders as such address appears in the Note register.

     The Discount Notes are issuable only in fully registered form, without
coupons, in denominations of $1,000 at final maturity and any integral multiple
thereof. No service charge shall be made for any registration of transfer or
exchange of the Discount Notes, but the Company may require payment of a sum
sufficient to cover any transfer tax or other similar governmental charge
payable in connection therewith.
   
     The Discount Notes will mature on July 1, 2007 and will be limited to
$57,650,103.55 aggregate principal amount at maturity. The Discount Notes are
senior unsecured obligations of Holdings, ranking PARI PASSU in right of payment
with other senior unsecured Indebtedness of Holdings. The Discount Notes are
senior in right of payment to subordinated Indebtedness of Holdings, including
Holdings' guarantee of the Notes. The Discount Notes and TPC Holding's guarantee
are effectively subordinated to secured indebtedness of Holdings, including
Holdings' guarantee of Indebtedness of TPC under the Bank Credit Agreement, as
to the assets of Holdings securing such Indebtedness, and to all Indebtedness
and other liabilities and commitments (including trade payables and lease
obligations) of Holdings' Subsidiaries permitted under the Limitation on
Indebtedness covenant described below. Any right of Holdings to receive assets
of any of its Subsidiaries upon the latter's liquidation or reorganization (and
the consequent right of the Discount Note holders to participate in those
assets) will be effectively subordinated to the claims of that Subsidiary's
creditors, except to the extent that Holdings is itself recognized as a creditor
of such Subsidiary, in which case the claims of Holdings or the Discount Note
Holders would still be subordinated to any Indebtedness secured by the assets of
such Subsidiary and to any Indebtedness of such Subsidiary senior to that held
by Holdings. See "Risk Factors-Effective Subordination," "Description of the
Discount Notes" and "Description of the Bank Credit Agreement." As of March
3, 1998, (i) Holdings had approximately $96.0 million of secured senior
Indebtedness outstanding (consisting of Holdings' guarantee of the Company's
Indebtedness under the Bank Credit Agreement), $37.0 million of senior unsecured
Indebtedness outstanding (consisting of the portion of the issue price of the
Units allocated for accounting purposes to the Discount Notes) and (ii)
Holdings' Subsidiaries would have had approximately $326.3 million of
Indebtedness outstanding (including the Notes). Substantially all of the
operations of Holdings will be conducted through its Subsidiaries and,
therefore, Holdings will be dependent upon the cash flow of its Subsidiaries to
meet its obligations, including its obligations under the Discount Notes. See
"Risk Factors -- Dependence on Subsidiary Cash Flow."
    
                                       56
<PAGE>
   
     The Discount Notes are being offered at a substantial discount from their
principal amount at maturity. Cash interest will not accrue on the Discount
Notes prior to July 1, 2001. Thereafter, except as otherwise described below,
cash interest on the Discount Notes will be payable at the applicable rate set
forth on the front cover of this Prospectus, semiannually on each January 1 and
July 1, commencing January 1, 2002, to the Person in whose name the Discount
Notes (or any predecessor Discount Note) are registered at the close of business
on the December 15 and June 15 next preceding such interest payment date. Cash
interest will accrue from the most recent interest payment date to which
interest has been paid or duly provided for or, if no interest has been paid or
provided for, from July 1, 2001. TPC Holding fully and unconditionally
guarantees the due and punctual payment of the principal of, interest on and all
other amounts payable under the Discount Notes when they become due and payable,
whether upon maturity, upon acceleration, by call for redemption, upon
repurchase or purchase pursuant to a Change of Control or Asset Disposition or
otherwise. The guarantee will not be discharged with respect to any Discount
Note except by payment in full of principal, interest and all other amounts
payable.
    
     Under the terms of the guarantee executed by Holdings in connection with
the Bank Credit Agreement as in effect on the date of the Discount Notes
Indenture, no payment or distribution of any assets of Holdings of any kind or
character, whether in cash, property or securities (other than Permitted
Securities), may be made by Holdings on account of principal (or premium, if
any) of the Discount Notes or on account of the purchase or redemption or other
acquisition of the Discount Notes prior to the Stated Maturity of the principal
of the Discount Notes until payment in full in cash of all amounts owned under
the Bank Credit Agreement; PROVIDED, HOWEVER,that prior to such payment in full
of all such amounts owed under the Bank Credit Agreement, up to 30% of the
aggregate Accreted Value of the Discount Notes may be redeemed by Holdings on or
prior to July 1, 1998, at the option of Holdings, from the net proceeds of a
Public Equity Offering following which there is a Public Market. See
" -- Redemption -- OPTIONAL REDEMPTION."

REDEMPTION

     OPTIONAL REDEMPTION.  The Discount Notes are subject to redemption at any
time on or after July 1, 2001, at the option of Holdings, in whole or in part,
upon not less than 30 nor more than 60 days' prior notice in amounts of $1,000
principal amount at final Maturity or an integral multiple thereof at the
following redemption prices (expressed as percentages of the Accreted Value), if
redeemed during the 12-month period beginning July 1 of the year indicated
below:

                                        REDEMPTION
YEAR                                       PRICE

2002.................................      105.75
2003.................................      104.75
2004.................................      103.75
2005 and thereafter..................      100.00

and thereafter at 100% of the principal amount at final Maturity, in each case
together with accrued and unpaid interest, if any, to the redemption date
(subject to the right of Discount Note Holders on the relevant record dates to
receive interest due on relevant interest payment dates).

     Notwithstanding the foregoing, up to 30% of the aggregate Accreted Value of
the Discount Notes are redeemable, at any time, on or prior to July 1, 1998 at
the option of Holdings, within 45 days of the notice of the sale of Qualified
Capital Stock of Holdings or the Company in a Public Equity Offering from the
net proceeds of such sale, following which there is a Public Market, upon not
less than 30 nor more than 60 days' prior notice in amounts of $1,000 principal
amount at final Maturity or an integral multiple thereof at a redemption price
equal to 113.5% of the Accreted Value thereof, together with accrued and unpaid
interest, if any, to the redemption date (subject to the right of Discount Note
Holders on the relevant record date to receive interest due on interest payment
dates). If less than all of the Discount Notes are to be

                                       57
<PAGE>
redeemed, the Discount Notes Trustee shall select the Discount Notes or the
portion thereof to be redeemed pro rata.

     The Bank Credit Agreement prohibits Holdings from making any optional or
mandatory payment of principal, or redemption of, the Discount Notes without the
consent of the Banks, other than the redemption of all of the Discount Notes
from the net proceeds of a Public Equity Offering as described above.

     PURCHASE OF DISCOUNT NOTES UPON CHANGE IN CONTROL OR HOLDINGS ASSET SALE.
Each Discount Note Holder will have certain rights to require Holdings to
purchase such Discount Note Holder's Discount Notes upon the occurrence of a
Change in Control. See " -- Purchase of Discount Notes upon a Change in
Control" below. Under certain circumstances, Holdings shall be required to make
an offer to purchase all or a portion of the Discount Notes with proceeds
received in connection with an Asset Sale. See " -- Certain
Covenants -- DISPOSITION OF PROCEEDS OF ASSET SALES" below.

SINKING FUND

     The Discount Notes are not entitled to the benefit of any sinking fund.

CHANGE OF CONTROL

     Upon the occurrence of any of the following events (each a "Change of
Control"), each Holder shall have the right to require that the Company
repurchase such Holder's Securities at a purchase price in cash equal to 101% of
the Accreted Value thereof plus accrued and unpaid interest, if any, to the date
of purchase (subject to the right of holders of record on the relevant record
date to receive interest due on the relevant interest payment date):

          (i) any "person" (as such term is used in Sections 13(d) and 14(d)
     of the Exchange Act), other than one or more Permitted Holders, is or
     becomes the beneficial owner (as defined in Rules 13d-3 and 13d-5 under the
     Exchange Act, except that for purposes of this clause (i) such person shall
     be deemed to have "beneficial ownership" of all shares that any such
     person has the right to acquire, whether such right is exercisable
     immediately or only after the passage of time), directly or indirectly, of
     more than 35% of the total voting power of the then outstanding Voting
     Stock of Holdings; PROVIDED, HOWEVER, that the Permitted Holders
     beneficially own (for purposes of this clause (i), the Permitted Holders
     shall be deemed to beneficially own any Voting Stock of a corporation (the
     "specified corporation") held by any other corporation (the "parent
     corporation") so long as the Permitted Holders beneficially own (as so
     defined), directly or indirectly, in the aggregate a majority of the voting
     power of the Voting Stock of the parent corporation), directly or
     indirectly, in the aggregate a lesser percentage of the total voting power
     of the then outstanding Voting Stock of Holdings than such other person and
     do not have the right or ability by voting power, contract or otherwise to
     elect or designate for election a majority of the Board of Directors (for
     the purposes of this clause (i), such other person shall be deemed to
     beneficially own any Voting Stock of a specified corporation held by a
     parent corporation, if such other person is the beneficial owner (as
     defined in this clause (i)), directly or indirectly, of more than 35% of
     the voting power of the Voting Stock of such parent corporation and the
     Permitted Holders beneficially own (as defined above), directly or
     indirectly, in the aggregate a lesser percentage of the voting power of the
     Voting Stock of such parent corporation and do not have the right or
     ability by voting power, contract or otherwise to elect or designate for
     election a majority of the board of directors of such parent corporation);

          (ii) during any period of two consecutive years, individuals who at
     the beginning of such period constituted the Board of Directors of
     Holdings, TPC Holding or TPC (together with any new directors whose
     election by such Board of Directors or whose nomination for election by the
     shareholders of Holdings, TPC Holding or TPC, as the case may be, was
     approved by a vote of 66 2/3% of the directors of Holdings, TPC Holding or
     TPC, as the case may be, then still in office who were either directors at
     the beginning of such period or whose election or nomination for election
     was previously so approved) cease for any reason to constitute a majority
     of the Board of Directors of Holdings, TPC Holding or TPC, as the case may
     be, then in office;

                                       58
<PAGE>
          (iii) the merger or consolidation of Holdings, TPC Holding or the
     Company with or into another Person or the merger of another Person with or
     into Holdings, TPC Holding or the Company, or the sale of all or
     substantially all the assets of Holdings, TPC Holding or the Company to
     another Person (in each case other than a Person that is controlled by the
     Permitted Holders), and, in the case of any such merger or consolidation,
     the securities of Holdings, TPC Holding or the Company, as applicable, that
     are outstanding immediately prior to such transaction and which represent
     100% of the aggregate voting power of the Voting Stock of Holdings, TPC
     Holding or the Company, as applicable, are changed into or exchanged for
     cash, securities or property, unless pursuant to such transaction such
     securities are changed into or exchanged for, in addition to any other
     consideration, securities of the surviving corporation or a parent
     corporation that owns all of the capital stock of such corporation that
     represent immediately after such transaction, at least 35% of the aggregate
     voting power of the Voting Stock of the surviving corporation or such
     parent corporation, as the case may be; or

          (iv) Holdings directly or indirectly ceases to own 100% of the Capital
     Stock of TPC.

     Within 30 days following any Change of Control, the Company shall mail a
notice to the Trustee and to each Holder stating: (1) that a Change of Control
has occurred and that such Holder has the right to require the Company to
purchase such Holder's Discount Notes at a purchase price in cash equal to 101%
of the Accreted Value thereof plus accrued and unpaid interest, if any, to the
date of purchase (subject to the right of holders of record on the relevant
record date to receive interest on the relevant interest payment date); (2) the
circumstances and relevant facts regarding such Change of Control (including
information with respect to pro forma historical income, cash flow and
capitalization after giving effect to such Change of Control); (3) the
repurchase date (which shall be no earlier than 45 days nor later than 60 days
from the date such notice is mailed); and (4) the instructions determined by the
Company, consistent with the covenant described hereunder, that a Holder must
follow in order to have its Discount Notes purchased.

     The Company shall comply, to the extent applicable, with the requirements
of Section 14(e) of the Exchange Act and any other securities laws or
regulations in connection with the repurchase of Discount Notes pursuant to this
covenant described hereunder. To the extent that the provisions of any
securities laws or regulations conflict with the provisions of the covenant
described hereunder, the Company shall comply with the applicable securities
laws and regulations and shall not be deemed to have breached its obligations
under the covenant described hereunder by virtue thereof.

     The use of the terms "all or substantially all" and "substantially as an
entirety" in provisions of the Discount Notes Indenture such as clause (iii) of
the definition of "Change in Control" and under "-- Merger and
Consolidation" has no clearly established meaning under New York law (which
governs the Discount Notes Indenture) and has been the subject of limited
judicial interpretation in few jurisdictions. Accordingly, there may be a degree
of uncertainty in ascertaining whether a particular transaction would involve a
disposition of "all or substantially all" of the assets of a person, or a
disposition of such assets "substantially as an entirety," which uncertainty
should be considered by prospective investors in the Discount Notes.

     Subject to the limitations discussed below, TPC, TPC Holding or Holdings
could, in the future, enter into certain transactions, including acquisitions,
refinancings or other recapitalizations, that would not constitute a Change of
Control under the Discount Notes Indenture, but that could increase the amount
of indebtedness outstanding at such time or otherwise affect TPC's, TPC
Holding's or Holdings' capital structure or credit ratings. Restrictions on the
ability of Holdings to incur additional Indebtedness are contained in the
covenants described under "-- Certain Covenants -- Limitation on Indebtedness"
and "-- Limitation on Indebtedness and Preferred Stock of Restricted
Subsidiaries." Such restrictions can only be waived with the consent of the
holders of a majority in principal amount of the Discount Notes, as the case may
be, then outstanding. Except for the limitations contained in such covenants,
however, the Discount Notes Indenture does not contain any covenants or
provisions that may afford holders of the Discount Notes protection in the event
of a highly leveraged transaction.

     If a Change of Control offer is made, there can be no assurance that
Holdings will have available funds sufficient to pay the purchase price for all
of the Discount Notes that might be delivered by holders of the

                                       59
<PAGE>
Discount Notes seeking to accept the Change of Control offer. The failure of
Holdings to make or consummate the Change of Control offer or pay the purchase
price when due will give the Discount Notes Trustee and the holders of the
Discount Notes the rights described under "-- Events of Default."

     The existence of a holder's right to require Holdings to offer to
repurchase such holder's Discount Notes upon a Change of Control may deter a
third party from acquiring Holdings in a transaction which constitutes a Change
of Control.

     Holdings' guarantee of TPC's obligations under the Bank Credit Agreement,
under certain circumstances, prohibits Holdings from purchasing any Discount
Notes prior to June 30, 2004, and also provides that the occurrence of certain
change of control events with respect to TPC, TPC Holding and Holdings
constitutes a default thereunder. In the event a Change of Control occurs at a
time when Holdings is prohibited from purchasing Discount Notes, Holdings could
seek the consent of its lenders to the purchase of Discount Notes or could
attempt to refinance the borrowings that contain such prohibition. If Holdings
does not obtain such a consent or repay such borrowings, Holdings will remain
prohibited from purchasing Discount Notes. In such case, Holdings' failure to
purchase tendered Discount Notes would constitute an Event of Default under the
Discount Notes Indenture which would, in turn, constitute a default under the
Bank Credit Agreement.

     Future indebtedness of Holdings may contain prohibitions on the occurrence
of certain events that would constitute a Change of Control or require such
indebtedness to be repaid or repurchased upon a Change of Control. Moreover, the
exercise by the holders of their right to require Holdings to repurchase the
Discount Notes could cause a default under such indebtedness, even if the Change
of Control itself does not, due to the financial effect of such repurchase on
Holdings. Finally, Holdings' ability to pay cash to the holders of Discount
Notes following the occurrence of a Change of Control may be limited by
Holdings' then existing financial resources. There can be no assurance that
sufficient funds will be available when necessary to make any required
repurchases. The provisions under the Discount Notes Indenture relating to
Holdings' obligation to make an offer to repurchase the Discount Notes as a
result of a Change of Control may be waived or modified with the written consent
of the holders of a majority in principal amount of the Discount Notes.

(other than Indebtedness permitted by clauses (1) through (9) above or paragraph

     (d)  For purposes of determining compliance with the covenant entitled

above, Holdings, in its sole discretion, will classify such item of Indebtedness

any consensual encumbrance or restriction on the ability of any Restricted

purchase of Indebtedness (other than any Disqualified Stock) of Holdings (other
than Indebtedness owed to an Affiliate of Holdings) or Indebtedness of any
Subsidiary (other than Indebtedness owed to Holdings or an

                                       64
<PAGE>
Affiliate of Holdings other than the Huff Alternative Income Fund, L.P., or any
Affiliate thereof), in each case within one year from the later of the receipt
of such Net Available Cash and the date the offer described in clause (b) below
is consummated; PROVIDED, HOWEVER, that in connection with any prepayment,
repayment or purchase of Indebtedness pursuant to clause (A), (C) or (D) above,
Holdings or such Restricted Subsidiary shall retire such Indebtedness and shall
cause the related loan commitment (if any) to be permanently reduced in an
amount equal to the principal amount so prepaid, repaid or purchased.
Notwithstanding the foregoing provisions of this paragraph, Holdings and its
Restricted Subsidiaries shall not be required to apply any Net Available Cash in
accordance with this paragraph except to the extent that the aggregate Net
Available Cash from all Asset Dispositions which are not applied in accordance
with this paragraph exceeds $3.5 million. Pending application of Net Available
Cash pursuant to this covenant, such Net Available Cash shall be invested in
Temporary Cash Investments. Notwithstanding the foregoing, any Asset Disposition
which is also an Asset Disposition governed by the Notes Indenture shall satisfy
this convenant if such Asset Disposition is made, and the Net Available Cash
therefrom applied, in accordance with the terms of the Notes Indenture.
Notwithstanding anything contained in this "-- Certain Covenants" section to
the contrary, the Company shall not sell, convey, pledge, hypothecate or
otherwise transfer the Houston Facility substantially as an entirety in one
transaction or a series of related transactions to any Person (other than a
Restricted Subsidiary), except for (i) pledges or security interests granted in
connection with securing Indebtedness borrowed under the Bank Credit Agreement,
and (ii) transactions that comply with the "-- Merger and Consolidation"
covenant described below.

     For the purposes of this covenant, the following are deemed to be cash or
cash equivalents: (x) the express assumption of any Indebtedness of a Restricted
Subsidiary other than TPC Holding and the release of Holdings or such Restricted
Subsidiary from all liability on such Indebtedness in connection with such Asset
Disposition and (y) securities received by Holdings or any Restricted Subsidiary
from the transferee that are converted by the Company or such Restricted
Subsidiary into cash within 90 days of closing the transaction.

     (b)  In the event of an Asset Disposition that requires the purchase of the
Discount Notes pursuant to clause (a)(ii)(A) or (C) above, Holdings will be
required to purchase Discount Notes tendered pursuant to an offer by Holdings
for the Discount Notes at a purchase price of 100% of their Accreted Value
(without premium) plus accrued but unpaid interest in accordance with the
procedures (including prorating in the event of oversubscription) set forth in
the Discount Notes Indenture. If the aggregate purchase price of the Discount
Notes tendered pursuant to such offer is less than the Net Available Cash
allotted to the purchase thereof, Holdings will be required to apply the
remaining Net Available Cash in accordance with clause (a)(ii)(D) above.

     (c)  Holdings shall comply, to the extent applicable, with the requirements
of Section 14(e) of the Exchange Act and any other securities laws or
regulations in connection with the repurchase of Discount Notes pursuant to this
covenant. To the extent that the provisions of any securities laws or
regulations conflict with provisions of this covenant, Holdings shall comply
with the applicable securities laws and regulations and shall not be deemed to
have breached its obligations under this clause by virtue thereof.

     LIMITATION ON AFFILIATE TRANSACTIONS.  (a)  Holdings shall not, and shall
not permit any Restricted Subsidiary to, enter into any transaction (including
the purchase, sale, lease or exchange of any property or the rendering of any
service) with any Affiliate of Holdings (an "Affiliate Transaction") unless
the terms thereof (1) are no less favorable to the Company or such Restricted
Subsidiary than those that could be obtained at the time of such transaction in
a comparable transaction on arm's-length dealings with a Person who is not such
an Affiliate, (2) if such Affiliate Transaction involves an amount in excess of
$2.5 million, (i) are set forth in writing and (ii) have been approved by a
majority of the members of the Board of Directors of Holdings having no material
personal financial stake in such Affiliate Transaction and (3) if such Affiliate
Transaction involves an amount in excess of $5 million, have been determined by
a nationally recognized investment banking firm to be fair, from a financial
standpoint, to Holdings or its Restricted Subsidiary, as the case may be.

                                       65
<PAGE>
     (b)  The provisions of the foregoing paragraph (a) shall not prohibit (i)
any Restricted Payment permitted to be paid pursuant to the covenant described
under "-- Limitation on Restricted Payments," or any payment or transaction
specifically excepted from the definition of Restricted Payment, (ii) any
issuance of securities, or other payments, awards or grants in cash, securities
or otherwise pursuant to, or the funding of, employment arrangements, stock
options and stock ownership plans approved by the Board of Directors of Holdings
or the board of directors of the relevant Restricted Subsidiary, (iii) the grant
of stock options or similar rights to employees and directors of Holdings
pursuant to plans approved by the Board of Directors of Holdings or the board of
directors of the relevant Restricted Subsidiary, (iv) loans or advances to
officers, directors or employees in the ordinary course of business, (v) the
payment of reasonable fees to directors of Holdings and its Restricted
Subsidiaries who are not employees of Holdings or its Restricted Subsidiaries,
(vi) any Affiliate Transaction between Holdings and a Wholly Owned Subsidiary or
between Wholly Owned Subsidiaries, (vii) the purchase of or the payment of
Indebtedness of or monies owed by Holdings or any of its Restricted Subsidiaries
for goods or materials purchased, or services received, in the ordinary course
of business, (viii) the purchase of or payment of Indebtedness of or monies owed
by Holdings or any of its Restricted Subsidiaries or fees to be paid to Sterling
or any Affiliate of Sterling, in each case pursuant to a written agreement in
existence on the Issue Date, and (ix) the Tax Sharing Agreement and any payments
thereunder, and (x) any Affiliate Transaction among Holdings or any Subsidiary
and The Huff Alternative Income Fund, L.P. or any of its Affiliates pursuant to
agreements in existence on the Issue Date.

     LIMITATION ON THE SALE OR ISSUANCE OF CAPITAL STOCK OF RESTRICTED
SUBSIDIARIES.  Holdings shall not sell or otherwise dispose of any shares of
Capital Stock of a Restricted Subsidiary, and shall not permit any Restricted
Subsidiary, directly or indirectly, to issue or sell or otherwise dispose of any
shares of its Capital Stock except (i) to Holdings or a Wholly Owned Subsidiary
or (ii) if, immediately after giving effect to such issuance, sale or other
disposition, such Restricted Subsidiary remains a Restricted Subsidiary;
PROVIDED, HOWEVER, that in connection with any such sale or disposition of
Capital Stock Holdings or any such Restricted Subsidiary complies with the
covenant described under "-- Limitation on Sales of Assets and Subsidiary
Stock"; PROVIDED, FURTHER, HOWEVER,that in no event may TPC Holding, Holdings
or any Restricted Subsidiary that owns the Houston Facility dispose of its
Capital Stock pursuant to clause (ii).

     MERGER AND CONSOLIDATION.  Holdings shall not consolidate with or merge
with or into any other corporation or sell, convey, transfer or lease its
properties and assets, in one transaction or a series of transactions,
substantially as an entirety to any Person or group of affiliated Persons or
permit any of its Restricted Subsidiaries to enter into any such transaction or
series of transactions if such transaction or series of transactions would
result in a sale, conveyance, transfer, or lease substantially as an entirety of
the properties and assets of Holdings and its Restricted Subsidiaries on a
consolidated basis to any Person or any group of affiliated Persons, unless: (i)
the resulting, surviving or transferee Person or Persons (the "Successor
Company") shall be in the case of a transaction in which Holdings is a party, a
corporation and, in the case of a transaction in which any Restricted Subsidiary
is a party, a Person organized and existing under the laws of the United States
of America, any State thereof or the District of Columbia and the Successor
Company in the case of a transaction in which Holdings is a party (if not
Holdings) shall expressly assume, by an indenture supplemental thereto, executed
and delivered to the Discount Notes Trustee, in form satisfactory to the
Discount Notes Trustee, all the obligations of Holdings under the Discount Notes
and the Discount Notes Indenture; (ii) immediately after giving effect to such
transaction on a pro forma basis (and treating any Indebtedness which becomes an
obligation of the Successor Company or any Subsidiary as a result of such
transaction as having been Incurred by such Successor Company or such Subsidiary
at the time of such transaction), no Default shall have occurred and be
continuing; (iii) immediately after giving effect to such transaction, in the
case of a sale, conveyance, transfer, or lease pursuant to which Holdings or any
of its Restricted Subsidiaries other than TPC and its Restricted Subsidiaries is
a party, the Successor Company would be able to Incur an additional $1.00 of
Indebtedness pursuant to the first sentence of paragraph (a) of the covenant
described under " -- Certain Covenants -- Limitation on Indebtedness" or, in
the case of a sale, conveyance, transfer, or lease pursuant to which TPC or any
of its Restricted Subsidiaries is a party, the Successor Company would be able
to Incur an additional

                                       66
<PAGE>
$1.00 of Indebtedness pursuant to the first sentence of paragraph (b) of the
covenant described under " -- Certain Covenants -- Limitation on Indebtedness"
(and in each such case treating any Indebtedness not previously an obligation of
Holdings or any Subsidiary which becomes an obligation of the Successor Company
or any Subsidiary in connection with or as a result of such transaction as
having been Incurred by such Successor Company or such Subsidiary at the time of
such transaction); (iv) immediately after giving effect to such transaction, the

Notwithstanding the foregoing clauses (ii), (iii) and (iv), any Restricted
Subsidiary may consolidate with, merge into or transfer all or part of its
properties and assets to TPC and TPC Holding may merge with and into TPC.

     TPC Holding shall not consolidate with or merge with or into any other
Person or convey, transfer or lease its properties and assets, in one
transaction or a series of transactions, substantially as an entirety to any
Person or group of affiliated Persons, unless: (i) The resulting, surviving or
transferee Person (the "TPC Holding Successor Company") shall be a corporation
organized and existing under the laws of the United States of America, any State
thereof or the District of Columbia and the Successor Company (if not TPC
Holding) shall expressly assume, by an indenture supplemental thereto, executed
and delivered to the Discount Notes Trustee, in form satisfactory to the
Discount Notes Trustee, all the obligations of TPC Holding under its Guarantee
of the Discount Notes and the Discount Notes Indenture; (ii) immediately after
giving effect to such transaction (and treating any Indebtedness which becomes
an obligation of the TPC Holding Successor Company or any Subsidiary as a result
of such transaction as having been incurred by such Successor Company or such
Subsidiary at the time of such transaction), no Default shall have occurred and
be continuing; and (iii) TPC Holding shall have delivered to the Discount Notes
Trustee an officers' certificate and an Opinion of Counsel, each stating that
such consolidation, merger or transfer and such supplemental indenture (if any)
comply with the Discount Notes Indenture. Notwithstanding the foregoing, TPC
Holding may merge with and into either TPC or Holdings.

     SEC REPORTS.  Notwithstanding that the Company may not be required to
remain subject to the reporting requirements of Section 13 or 15(d) of the
Exchange Act, Holdings shall provide the Trustee and Discount Notes Holders with
such annual reports and such information, documents and other reports as are
specified in Sections 13 and 15(d) of the Exchange Act and applicable to a U.S.
corporation subject to such Sections, such information, documents and other
reports to be so filed and provided at the times specified for the filing of
such information, documents and reports under such Sections.

DEFAULTS

     An Event of Default is defined in the Discount Notes Indenture as (i) a
default in the payment of interest on any Discount Note, when due, continued for
30 days, (ii) a default in the payment of principal of any Discount Note, when
due at its Stated Maturity, upon optional redemption, upon required repurchase,
upon declaration or otherwise, (iii) the failure by the Company to comply with
its obligations under "-- Certain Covenants  -- Merger and Consolidation"
above, (iv) the failure by the Company to comply for 30 days after notice with
any of its obligations in the covenants described above under "Change of
Control" (other than a failure to purchase Discount Notes) or under
"-- Certain Covenants" under "-- Limitation on Indebtedness,"
"-- Limitation on Indebtedness and Preferred Stock of Restricted
Subsidiaries," "-- Limitation on Restricted Payments," "-- Limitation on
Restrictions on Distributions from Restricted Subsidiaries," -- "Limitation on
Sales of Assets and Subsidiary Stock," " -- Limitation on Affiliate
Transactions," "Limitation on the Sale or Issuance of Capital Stock of
Restricted Subsidiaries," or "-- SEC Reports," (v) the failure by Holdings to
comply for 60 days after notice with its other agreements contained in the
Discount Notes Indenture, (vi) Indebtedness of Holdings or any Significant
Subsidiary is not paid within any applicable grace period after final maturity
or is accelerated by the holders thereof because of a default and the total
amount of such Indebtedness unpaid or accelerated exceeds $5 million (the
"cross acceleration provision"), (vii) certain events of bankruptcy,
insolvency or

                                       67
<PAGE>
reorganization of Holdings, or any Significant Subsidiary (the "bankruptcy
provisions") (viii) any judgment or decree for the payment of money in excess
of $5 million is entered against the Company or any Significant Subsidiary,
remains outstanding for a period of 60 days following such judgment and is not
discharged, waived or stayed within 10 days after notice (the "judgment default
provision") or (ix) the Security Guarantee shall cease to be, or be asserted in
writing by Holdings or TPC Holding not to be, in effect. However, a default
under clause (iv) or (v) will not constitute an Event of Default until the
Discount Notes Trustee or the holders of 25% in principal amount at final
maturity of the outstanding Discount Notes notify Holdings of the default and
Holdings does not cure such default within the time specified after receipt of
such notice.

     If an Event of Default (other than the bankruptcy provisions relating to
Holdings) occurs and is continuing, the applicable Trustee or the holders of at
least 25% in principal amount at final maturity of the outstanding Discount
Notes may declare the principal of and accrued but unpaid interest on all the
Discount Notes to be due and payable. Upon such a declaration, such principal
and interest shall be due and payable immediately. If an Event of Default
relating to the bankruptcy provisions relating to Holdings occurs and is
continuing, the principal of and interest on all the Discount Notes will IPSO
FACTO become and be immediately due and payable without any declaration or other
act on the part of the Discount Notes Trustee or any holders of the Discount
Notes. Under certain circumstances, the holders of a majority in principal
amount of the outstanding Discount Notes may rescind any such acceleration with
respect to the Discount Notes and its consequences.

     Subject to the provisions of the Discount Notes Indenture relating to the
duties of the Discount Notes Trustee, in case an Event of Default occurs and is
continuing, such Discount Notes Trustee will be under no obligation to exercise
any of the rights or powers under the applicable Indenture at the request or
direction of any of the holders of the Discount Notes unless such holders have
offered to the Discount Notes Trustee reasonable indemnity or security against
any loss, liability or expense. Except to enforce the right to receive payment
of principal, premium (if any) or interest when due, no holder of a Discount
Note may pursue any remedy with respect to the Discount Notes Indenture or the
Discount Notes unless (i) such holder has previously given the Discount Notes
Trustee notice that an Event of Default is continuing, (ii) holders of at least
25% in principal amount at final maturity of the outstanding Discount Notes have
requested the Discount Notes Trustee to pursue the remedy, (iii) such holders
have offered the Discount Notes Trustee reasonable security or indemnity against
any loss, liability or expense, (iv) the Discount Notes Trustee has not complied
with such request within 60 days after the receipt thereof and the offer of
security or indemnity and (v) the holders of a majority in principal amount at
final maturity of the outstanding Discount Notes have not given the Discount
Notes Trustee a direction inconsistent with such request within such 60-day
period. Subject to certain restrictions, the holders of a majority in principal
amount at final maturity of the outstanding Discount Notes are given the right
to direct the time, method and place of conducting any proceeding for any remedy
available to the Discount Notes Trustee or of exercising any trust or power
conferred on the Discount Notes Trustee. The Discount Notes Trustee, however,
may refuse to follow any direction that conflicts with law or the Discount Notes
Indenture or that the Discount Notes Trustee determines is unduly prejudicial to
the rights of any other holder of a Discount Notes, or that would involve the
Discount Notes Trustee in personal liability. A holder's right to individually
institute a suit for enforcement of the payment of principal or interest,
however, is not impaired by the Event of Default provisions.

     The Discount Notes Indenture provides that if a Default occurs and is
continuing and is known to the Discount Notes Trustee, such Trustee must mail to
each holder of the Discount Notes notice of the Default within 90 days after it
occurs. Except in the case of a Default in the payment of principal of or
interest on any Discount Notes, the Discount Notes Trustee may withhold notice
if and so long as the board of directors, the executive committee or a committee
of its trust officers determines that withholding notice is not opposed to the
interest of the holders of the Discount Notes. In addition, Holdings is required
to deliver to the Discount Notes Trustee, within 120 days after the end of each
fiscal year, a certificate indicating whether the signers thereof know of any
Default that occurred during the previous year. Holdings also is required to
deliver to the Discount Notes Trustee, within 30 days after the occurrence
thereof, written notice

                                       68
<PAGE>
of any event which would constitute certain Defaults, their status and what
action Holdings is taking or proposes to take in respect thereof.

AMENDMENTS AND WAIVERS

     Subject to certain exceptions, the Discount Notes Indenture may be amended
with the consent of the holders of a majority in principal amount at final
maturity of the Discount Notes then outstanding (including consents obtained in
connection with a tender offer or exchange for the Discount Notes) and any past
default or compliance with any provisions may also be waived with the consent of
the holders of a majority in principal amount at final maturity of the Discount
Notes then outstanding.

     Without the consent of each holder of an outstanding Discount Note affected
thereby, no amendment may (i) reduce the amount of Discount Notes whose holders
must consent to an amendment, (ii) reduce the rate of or extend the time for
payment of interest on any Discount Note, (iii) reduce the principal of or
extend the Stated Maturity of any Discount Note, (iv) reduce the premium payable
upon the redemption of any Discount Note or change the time at which any
Discount Note may be redeemed as described under "-- Optional Redemption"
above, (v) make any Discount Note payable in money other than that stated in the
Discount Note, (vi) impair the right of any holder of the Discount Notes to
receive payment of principal of and interest on such holder's Discount Notes on
or after the due dates therefor or to institute suit for the enforcement of any
payment on or with respect to such holder's Discount Notes, (vii) make any
change in the amendment provisions which require each holder's consent or in the
waiver provisions or (viii) make any change to the subordination provisions of
the Discount Notes Indenture that would adversely affect the holders of the
Discount Notes.

     Without the consent of any holder of the Discount Notes, Holdings and the
Discount Notes Trustee may amend the Discount Notes Indenture to cure any
ambiguity, omission, defect or inconsistency, to provide for the assumption by a
successor corporation of the obligations of Holdings under the Discount Notes
Indenture, to provide for uncertificated Discount Notes in addition to or in
place of certificated Discount Notes (provided that the uncertificated Discount
Notes are issued in registered form for purposes of Section 163(f) of the Code,
or in a manner such that the uncertificated Discount Notes are described in
Section 163(f)(2)(B) of the Code), to add guarantees with respect to the
Discount Notes, to secure the Discount Notes, to add to the covenants of
Holdings for the benefit of the holders of the Discount Notes or to surrender
any right or power conferred upon Holdings, to make any change that does not
adversely affect the rights of any holder of the Discount Notes or to comply
with any requirement of the SEC in connection with the qualification of the
Discount Notes Indenture under the Trust Indenture Act.

     The consent of the holders of the Discount Notes is not necessary under the
Discount Notes Indenture to approve the particular form of any proposed
amendment. It is sufficient if such consent approves the substance of the
proposed amendment.

     After an amendment under the Discount Notes Indenture becomes effective,
the Company is required to mail to holders of the Discount Note a notice briefly
describing such amendment. However, the failure to give such notice to all
holders of the Discount Notes, or any defect therein, will not impair or affect
the validity of the amendment.

TRANSFER

     The Discount Notes were issued in registered form and will be transferable
only upon the surrender of the Discount Notes being transferred for registration
of transfer. Holdings may require payment of a sum sufficient to cover any tax,
assessment or other governmental charge payable in connection with certain
transfers and exchanges.

DEFEASANCE

     Holdings at its option at any time may terminate all its obligations under
the Discount Notes, and the Discount Notes Indenture ("legal defeasance"),
except for certain obligations, including those respecting the defeasance trust
and obligations to register the transfer or exchange of the Discount Notes to
replace

                                       69
<PAGE>
mutilated, destroyed, lost or stolen Discount Notes, and to maintain a registrar
and paying agent in respect of the Discount Notes. In addition, Holdings at its
option at any time may terminate its obligations under "Change of Control" and
under the covenants described under "-- Certain Covenants" (other than the
covenant described under "-- Merger and Consolidation") (and any omission to
comply with such obligations shall not constitute a Default or Event of Default
with respect to the Discount Notes), the operation of the cross acceleration
provision, the bankruptcy provisions with respect to Significant Subsidiaries
and the judgment default provision described under "-- Defaults" above and the
limitations contained in clauses (iii) and (iv) of the first paragraph under,
"-- Certain Covenants -- Merger and Consolidation" above ("covenant
defeasance").

     Holdings may exercise its legal defeasance option notwithstanding its prior
exercise of its covenant defeasance option. If Holdings exercises its legal
defeasance option, payment of the Discount Notes may not be accelerated because
of an Event of Default with respect thereto. If Holdings exercises its covenant
defeasance option, payment of the Discount Notes may not be accelerated because
of an Event of Default specified in clause (iv), (vi), (vii) (with respect only
to Significant Subsidiaries) or (viii) under "-- Defaults" above or because of
the failure of Holdings to comply with clause (iii) or (iv) of the first
paragraph under "-- Certain Covenants -- Merger and Consolidation" above.

     In order to exercise either defeasance option, Holdings must irrevocably
deposit in trust (the "defeasance trust") with the Discount Notes Trustee
money or U.S. Government Obligations for the payment of principal of and
interest on the Discount Notes to redemption or maturity, as the case may be,
and must comply with certain other conditions, including delivery to the
Discount Notes Trustee of an Opinion of Counsel to the effect that holders of
the Discount Notes will not recognize income, gain or loss for Federal income
tax purposes as a result of such deposit and defeasance and will be subject to
Federal income tax on the same amount and in the same manner and at the same
times as would have been the case if such deposit and defeasance had not
occurred (and, in the case of legal defeasance only, such Opinion of Counsel
must be based on a ruling of the Internal Revenue Service or other change in
applicable Federal income tax law).

CONCERNING THE TRUSTEE

     Fleet National Bank is the Trustee under the Discount Notes Indenture and
has been appointed by Holdings as Registrar and Paying Agent with regard to the
Discount Notes. Such bank may also act as a depository of funds for or makes
loans to, and performs other services for, Holdings or its affiliates in the
ordinary course of business in the future. The corporate trust office of the
Discount Notes Trustee is located at 777 Main Street, Hartford, Connecticut
06115.

     The Holders of a majority in aggregate principal amount at final maturity
of the outstanding Discount Notes have the right to direct the time, method and
place of conducting any proceeding for exercising any remedy available to the
Discount Notes Trustee, or exercising any trust or power conferred on the
Trustee, provided that in each case (i) such direction shall not be in conflict
with any rule of law or with the Discount Notes Indenture, (ii) the Discount
Notes Trustee may take any other action deemed proper by the Trustee which is
not inconsistent with such direction, and (iii) the Trustee need not take any
action which might involve it in personal liability or be unjustly prejudicial
to the Holders not joining in such direction. The Discount Notes Indenture
provides that if an Event of Default occurs (and is not cured), the Discount
Notes Trustee will be required, in the exercise of its power, to use the degree
of care of a prudent man in the conduct of his own affairs. Subject to such
provisions, the Discount Notes Trustee will be under no obligation to exercise
any of its rights or powers under the Discount Notes Indenture at the request of
any Holder of Discount Notes, unless such Holder shall have offered to the
Discount Notes Trustee security and indemnity satisfactory to it against any
loss, liability or expense and then only to the extent required by the terms of
the the Discount Notes Indenture. The Discount Notes Trustee may resign from its
duties with respect to the Discount Notes at any time or may be removed by
Holdings. If the Discount Notes Trustee resigns, is removed or becomes incapable
of acting as Discount Notes Trustee or if a vacancy occurs in the office of the
Discount Notes Trustee for any cause, a successor Trustee shall be appointed in
accordance with the provisions of the Discount Notes Indenture.

                                       70
<PAGE>
     If the Discount Notes Trustee has or shall acquire a conflicting interest
within the meaning of the Trust Indenture Act, the Discount Notes Trustee shall
either eliminate such interest or resign, to the extent and in the manner
provided by, and subject to the provisions of, the Trust Indenture Act and the
Discount Notes Indenture. The Discount Notes Indenture also contains certain
limitations on the right of the Discount Notes Trustee, as a creditor of
Holdings, to obtain payment of claims in certain cases, or to realize on certain
property received by it in respect of any such claims, as security or otherwise.

GOVERNING LAW

     The Discount Notes Indenture provides that it and the Discount Notes will
be governed by, and construed in accordance with, the laws of the State of New
York without giving effect to applicable principles of conflicts of law to the
extent that the application of the law of another jurisdiction would be required
thereby.

outstanding or if the transaction giving rise to the need to calculate the
Consolidated Coverage Ratio is an Incurrence of Indebtedness, or both, EBITDA

any such Restricted Subsidiary for such period shall be included in such
Consolidated Net Income up to the aggregate amount of cash actually distributed
by such Restricted Subsidiary during such period to TPC or another Restricted
Subsidiary as a dividend or other distribution (subject, in the case of a
dividend or other distribution paid to another Restricted Subsidiary, to the
limitation contained in this clause) and (B) TPC's equity in a net loss of any
such Restricted Subsidiary for such period shall be included in determining such

                   MATERIAL FEDERAL INCOME TAX CONSIDERATIONS

     The following discussion represents the opinion of Bracewell & Patterson,
L.L.P., counsel to the Company, insofar as it relates to law and legal
conclusions concerning the material United States federal income tax
consequences relevant to the purchase, ownership and disposition of the Discount
Notes. This discussion does not address all aspects of federal income taxation
that may be relevant to particular investors in light of their personal
investment circumstances, nor does it address the federal income tax
consequences which may be relevant to certain types of investors subject to
special treatment under the federal income tax laws (for example, certain
financial institutions, insurance companies, tax-exempt entities,
broker-dealers, and taxpayers subject to the alternative minimum tax). In
addition, this discussion

                                       82
<PAGE>
does not discuss any aspects of state, local, or foreign tax laws. This
discussion assumes that investors will hold their Discount Notes as "capital
assets" (generally, property held for investment), within the meaning of
Section 1221 of the Code.

     No ruling from the Internal Revenue Service (the "IRS") will be requested
with respect to any of the matters discussed herein. There can be no assurance
that the IRS will not take a different position concerning the matters discussed
below and that such positions would not be sustained. BECAUSE INDIVIDUAL
CIRCUMSTANCES MAY DIFFER, EACH HOLDER OF DISCOUNT NOTES SHOULD CONSULT HIS OR
HER OWN TAX ADVISOR WITH RESPECT TO HIS OR HER PARTICULAR TAX SITUATION AND AS
TO ANY FEDERAL, FOREIGN, STATE, LOCAL OR OTHER TAX CONSIDERATIONS (INCLUDING ANY
POSSIBLE CHANGES IN TAX LAW) AFFECTING THE PURCHASE, OWNERSHIP AND DISPOSITION
OF THE DISCOUNT NOTES.

     This discussion is based on the provisions of the Code, existing and
proposed Treasury regulations promulgated thereunder (the "Regulations"),
judicial authority interpreting the Code, and current administrative rulings and
pronouncements of the IRS now in effect, all of which are subject to change at
any time by legislative, judicial or administrative action. Any such changes may
be retroactively applied in a manner that could result in federal income tax
consequences different from those discussed below and could adversely affect a
holder of Discount Notes.

UNITED STATES FEDERAL INCOME TAXATION OF UNITED STATES HOLDERS

     As used herein, the term "United States Holder" means a holder of
Discount Notes that is for United States federal income tax purposes (a) a
citizen or resident of the United States, (b) a corporation, partnership or
other entity created or organized in or under the laws of the United States or
of any political subdivision thereof, or (c) an estate or trust the income of
which is subject to United States federal income taxation regardless of source.

     CLASSIFICATION OF DISCOUNT NOTES.  The Discount Notes will be treated as
indebtedness for tax purposes. Set forth below is the expected federal income
tax treatment of the Discount Notes. The IRS, however, could assert that the
positions set forth below are improper. If so, a substantial portion of the
discussion set forth below would be inapplicable, and the tax consequences to
the holders of the Discount Notes would change, possibly with adverse tax
consequences.

     Pursuant to Section 385(c) of the Code, a United States Holder of a
Discount Note is required to treat such note as indebtedness for all United
States federal tax purposes unless such holder discloses any such inconsistent
treatment on his or her tax return. Section 385(c) is not binding on the IRS.

     AMOUNT OF ORIGINAL ISSUE DISCOUNT.  The Discount Notes were issued with
original issue discount within the meaning of Section 1273 of the Code. As a
result, a United States Holder of a Discount Note generally is required to
include such original issue discount in his or her gross income as interest
income on a constant yield to maturity basis, in advance of the receipt of cash
payments to which such income is attributable (regardless of whether the United
States Holder is a cash or accrual taxpayer) and generally in increasing amounts
over the life of the Discount Notes.

     The total amount of original issue discount with respect to a Discount Note
will be equal to the excess of the "stated redemption price at maturity" of
such Discount Note over the "issue price" of such Discount Note. The "issue
price" of the Discount Note is discussed in detail below. The "stated
redemption price at maturity" of a Discount Note will be equal to the sum of
all payments, whether denominated as interest or principal, required to be made
on such Discount Note other than payments of "qualified stated interest." A
qualified stated interest payment is generally any one of a series of stated
interest payments that are unconditionally payable at least annually at a single
fixed rate (with certain exceptions for lower rates paid during some periods)
applied to the outstanding principal amount of the debt instrument. Because
interest is not payable on the Discount Notes until January 1, 2002, none of the
interest payments will be payments of qualified stated interest and all such
payments will be included in the stated redemption price at maturity.

                                       83
<PAGE>
     Because the initial purchaser of the Discount Notes acquired these
securities only by purchasing Units (which included Common Stock), the Discount
Notes were treated as having been issued as an investment unit for federal
income tax purposes. The issue price of a Unit was equal to the first price at
which a substantial amount of Units was sold for money (excluding sales to bond
houses, brokers or similar persons or organizations acting in the capacity of
underwriters or wholesalers). The issue price for a Unit as so determined was
allocated between the Discount Note and the Common Stock that comprised the Unit
based on their relative fair market values at the time of issuance. Pursuant to
these rules, of the purchase price for each Unit, Holdings allocated $520.38 to
each Discount Note. This allocation, however, is not binding on the IRS, and
there can be no assurance that the IRS will not challenge Holding's
determination of the issue price of the Discount Notes. In addition, Holdings
determination of the issue price of the Discount Notes is not necessarily
indicative of the prices at which the Discount Notes may actually trade.

     TAXATION OF ORIGINAL ISSUE DISCOUNT.  The amount of original issue discount
to be included in a holder's gross income for any taxable year (regardless of
whether the holder uses the cash or accrual method of accounting) is the sum of
the "daily portions" of original issue discount with respect to the Discount
Notes for each day during the taxable year or portion of the taxable year in
which the holder holds such Discount Note ("accrued original issue discount").
The daily portion is determined by allocating to each day in any "accrual
period" a pro rata portion of the original issue discount allocable to that
accrual period. Accrual periods with respect to a Discount Note may be of any
length selected by the holder and may vary in length over the term of the
Discount Note as long as (i) no accrual period is longer than one year and (ii)
each scheduled payment of interest or principal on the Discount Note occurs on
either the first or final day of an accrual period. The amount of original issue
discount allocable to each accrual period will be equal to the excess of (a) the
product of the "adjusted issue price" of the Discount Note at the beginning of
an accrual period and the yield to maturity of such Discount Note (determined on
the basis of a compounding assumption that reflects the length of the accrual
period) over (b) the sum of the payments of qualified stated interest on the
Discount Note allocable to the accrual period. The "adjusted issue price" of a
Discount Note at the beginning of an accrual period will be equal to its
original issue price increased by all previously accrued original issue discount
(disregarding any reduction on account of acquisition premium described below)
and reduced by the amount of all previous cash payments on the Discount Note.
The yield to maturity is the interest rate, expressed as a constant annual
interest rate, that when used in computing the present value of all payments of
principal and interest to be paid in connection with the Discount Notes produces
an amount equal to the issue price of the Discount Notes.

     Holdings will provide certain information to the IRS, and will furnish
annually to record holders of the Discount Notes information with respect to
original issue discount during the calendar year. Because this information is
based upon the adjusted issue price of the Discount Note as if the holder were
the original holder of the instrument, subsequent holders who purchase the
Discount Notes for an amount other than the adjusted issue price and/or on a
date other than the end of an accrual period will be required to determine for
themselves the amount of original issue discount.

     A subsequent purchaser of a Discount Note having original issue discount
also will be required to include annual accruals of original issue discount in
gross income, for United States federal income tax purposes, in accordance with
the rules described above, but the amount of the original issue discount may
vary depending upon the amount paid for the debt instrument by the subsequent
purchasers.

     In the event of a Change in Control, Holdings will be required to offer to
redeem all of the Discount Notes. Based on the Regulations, the right of holders
of the Discount Notes to require redemption of the Discount Notes upon the
occurrence of a Change in Control will not affect the yield to maturity or the
accrual of original issue discount of the Discount Notes unless, based on all
the facts and circumstances as of the issue date, it is more likely than not
that a Change in Control giving rise to the redemption will occur. Holdings has
no present intention to treat the redemption provisions of the Discount Notes as
affecting the computation of the yield to maturity or the accrual of original
issue discount of any Discount Notes.

     ACQUISITION PREMIUM ON DISCOUNT NOTES.  If a United States Holder purchases
a Discount Note for an amount that is greater than its adjusted issue price as
of the purchase date but less than its stated redemption

                                       84
<PAGE>
price at maturity, the holder will be considered to have purchased such Discount
Note at an "acquisition premium." Under the acquisition premium rules of the
Code and Regulations promulgated thereunder, the amount of original issue
discount that such holder must include in its gross income with respect to such
Discount Note for any taxable year is generally reduced by the portion of such
acquisition premium properly allocable to such year.

     MARKET DISCOUNT.  If a United States Holder purchases a Discount Note,
subsequent to its initial issuance, for an amount that is less than the
"revised issue price" of the Discount Note as of the time of acquisition, the
amount of such difference will generally be treated as "market discount" for
United States federal income tax purposes, unless such difference is less than a
specified de minimis amount. The Code provides that the "revised issue price"
is the original issue price of a Discount Note plus the aggregate amount of
previously accrued original issue discount, without regard to any reductions for
acquisition premium, less payments other than qualified stated interest. Under
the market discount rules, a holder will be required to treat any principal
payment on, or any gain on the sale, exchange, retirement or other disposition
of Discount Notes as ordinary income to the extent of the accrued market
discount that has accrued while the instrument was held by such holder and that
has not previously been included in income. In addition, the holder may be
required to defer, until the maturity date of the Discount Note or its earlier
disposition in a taxable transaction, the deduction of all or a portion of the
interest expense on any indebtedness incurred or maintained to purchase or carry
such Discount Note.

     The Discount Notes provide for optional redemption and (in the case of a
Change in Control) mandatory offers to purchase, in whole or in part, prior to
maturity. If the Discount Notes were redeemed, a United States Holder generally
would be required to include in gross income as ordinary income the portion of
the gain recognized on the redemption attributable to accrued market discount,
if any.

     Any market discount will be considered to accrue ratably during the period
from the date of acquisition to the maturity date of the Discount Note, unless
the holder elects to accrue market discount on a constant yield basis. In
addition, a holder of a Discount Note may elect to include market discount in
income currently as it accrues (under either a ratable or constant yield
method). This election to include currently, once made, applies to all market
discount obligations acquired in or after the first taxable year to which the
election applies and may not be revoked without the consent of the IRS. If a
holder of Discount Notes makes such an election, the foregoing rules with
respect to the recognition of ordinary income on sales and other dispositions of
instruments, and with respect to the deferral of interest deductions incurred or
maintained to purchase or carry such debt instruments, would not apply.

     AMORTIZABLE BOND PREMIUM.  If a United States Holder purchases a Discount
Note for an amount that is greater than the sum of all payments payable on the
Discount Note after the purchase date, other than qualified stated interest,
such holder will be considered to have purchased such Discount Note with
"amortizable bond premium" equal in amount to such excess, and may elect to
amortize such premium, using a constant yield method, over the remaining term of
the Discount Note. The amount amortized in any year will be treated as a
reduction of the United States Holder's interest income (including original
issue discount) from the Discount Note in such year. An election to amortize
bond premium applies to all taxable debt obligations then owned and thereafter
acquired by the United States Holder and may be revoked only with the consent of
the IRS. The holder should consult with his or her tax advisor with respect to
the general applicability of the amortizable bond premium rules of Section 171
of the Code to such holder, and whether the holder should make an election under
these rules.

     ELECTION TO TREAT ALL INTEREST AS ORIGINAL ISSUE DISCOUNT.  A holder of a
Discount Note may elect to include all interest that accrues on the Discount
Note in gross income on a constant yield basis. For purposes of this election,
interest includes stated interest, original issue discount, market discount, de
minimis market discount and unstated interest, as adjusted by any amortizable
bond premium or acquisition premium.

     In applying the constant yield method to a Discount Note with respect to
which this election has been made, the issue price of the Discount Note will
equal the holder's basis in the Discount Note immediately after its acquisition,
the issue date of the Discount Note will be the date of its acquisition by the
holder, and

                                       85
<PAGE>
no payments on the Discount Note will be treated as payments of qualified stated
interest. The election will generally apply only to the Discount Note with
respect to which it is made and may not be revoked without the consent of the
IRS.

     If this election is made with respect to a Discount Note with amortizable
bond premium, the electing holder will be deemed to have elected to apply
amortizable bond premium against interest with respect to all debt instruments
with amortizable bond premium (other than debt instruments the interest on which
is excludable from gross income) held by the electing holder as of the beginning
of the taxable year in which the Discount Note with respect to which the
election is made is acquired. The deemed election with respect to amortizable
bond premium may not be revoked without the consent of the IRS.

     If the election to apply the constant yield method to all interest on a
Discount Note is made with respect to a Discount Note on which there is market
discount, the electing holder will be treated as having made the election
described above under "-- Market Discount" to include market discount in
income currently over the life of all debt instruments held or thereafter
acquired by such holder.

     SALE, EXCHANGE, REDEMPTION, RETIREMENT, OR OTHER DISPOSITION.  In general,
the United States Holder of a Discount Note will recognize gain or loss upon the
sale, exchange, redemption, retirement, or other disposition of such debt
instrument measured by the difference between (i) the amount of cash and the
fair market value of property received in exchange therefor (less any portion of
such amount that is allocable to accrued interest or original issue discount,
which amount generally will be taxable as ordinary income) and (ii) the United
States Holder's adjusted tax basis in such debt instrument.

     The initial tax basis in a Discount Note purchased by a United States
Holder on the original issuance of such security will be equal to the portion of
the issue price paid for the Unit allocable to the Discount Note, as discussed
in "-- Amount of Original Issue Discount." The United States Holder's initial
tax basis in the Discount Note will be increased by any accrued original issue
discount (net of all amortized acquisition premium) and any market discount
includable in such United States Holder's gross income, and decreased by the
amount of any cash payments received by such United States Holder, regardless of
whether such payments are denominated as principal or interest (other than
payments of qualified stated interest), and amortizable bond premium, if any,
deducted over the term of the Discount Notes.

     Any gain or loss on the sale, exchange, redemption, retirement, or other
disposition of a Discount Note should generally be capital gain or loss (except
as discussed in "-- Market Discount"), provided the Discount Note was a
capital asset in the hands of the United States Holder. Any capital gain or loss
will be long-term capital gain or loss or short-term capital gain or loss
depending on the amount of time the debt instrument has been held.

     CLASSIFICATION OF DISCOUNT NOTES AND APPLICABLE HIGH YIELD DISCOUNT
OBLIGATIONS.  Section 163 of the Code provides that all of the original issue
discount with respect to certain "applicable high yield discount obligations"
will be bifurcated into two elements -- (i) an interest element that is
deductible by the issuer only when paid and (ii) a disqualified portion for
which the issuer receives no deduction (the "disqualified portion"). The
United States Holder of an applicable high yield discount obligation must
continue to include original issue discount on the obligation as it accrues. A
corporate United States Holder of an applicable high yield discount obligation,
however, is allowed a dividends-received deduction for the part of the
disqualified portion of the original issue discount that would have been treated
as a dividend had it been distributed by the issuing corporation with respect to
its stock.

     The deduction by Holdings of original issue discount on the Discount Notes
will be limited because the Discount Notes constitute applicable high yield
discount obligations. Further, since the Discount Notes are applicable high
yield debt obligations, the disqualified portion of original issue discount will
equal the lesser of such original issue discount or the product of the total
original issue discount under the Discount Notes times the ratio of (a) the
excess of the yield to maturity over the sum of the applicable federal rate plus
six percentage points to (b) the yield to maturity.

     Corporate United States Holders will generally be eligible for the 70%
dividends received deduction with respect to the disqualified portion of
original issue discount on a Discount Note to the extent of

                                       86
<PAGE>
Holdings' accumulated or current earnings and profits. There can be no assurance
that Holdings will have any earnings and profits. In any year in which Holdings
has no earnings and profits, the disqualified portion of any original issue
discount would not be eligible for the dividends received deduction.

BACKUP WITHHOLDING

     Certain non-corporate United States Holders of Discount Notes may be
subject to backup withholding at the rate of 31% with respect to interest
(including original issue discount) and cash received in certain circumstances
upon the disposition of such securities. Generally, backup withholding is
applied only when the taxpayer (i) fails to furnish or certify its correct
taxpayer identification number to the payor in the manner required, (ii) is
notified by the IRS that it has failed to report payments of interest and
dividends properly, or (iii) under certain circumstances, fails to certify that
it has not been notified by the IRS that it is subject to backup withholding for
failure to report interest and dividend payments. Any amounts withheld under the
backup withholding rules will be allowed as a refund or credit against a United
States Holders's United States federal income tax liability, provided that such
United States Holder furnished the required information to the IRS.

UNITED STATES FEDERAL TAXATION OF NON-UNITED STATES HOLDERS

     This section discusses certain special rules applicable to a holder of
Discount Notes that is a Non-United States Holder. For purposes of this
discussion, a "Non-United States Holder" means a holder of Discount Notes that
is not (i) an individual who is a citizen or resident of the United States; (ii)
a corporation or partnership created or organized in the United States or under
the laws of the United States or any political subdivision thereof; or (iii) an
estate or trust whose income is includable in gross income for United States
federal income tax purposes regardless of its source.

     INTEREST AND ORIGINAL ISSUE DISCOUNT ATTRIBUTABLE TO THE DISCOUNT
NOTES.  Subject to the discussion of backup withholding set forth below,
payments of interest (including original issue discount) on the Discount Notes
to a Non-United States Holder who is the beneficial owner of a Discount Note
generally will not be subject to the 30% U.S. withholding tax under the
portfolio interest exemption of the Code; provided, that (i) the beneficial
owner of the Discount Note does not actually or constructively own 10% or more
of the total combined voting power of all classes of stock of Holdings entitled
to vote within the meaning of Section 871(h)(3) of the Code and the regulations
thereunder; (ii) such beneficial owner is not a controlled foreign corporation
that is related to Holdings through stock ownership; (iii) such beneficial owner
is not a bank whose receipt of interest on a Discount Note is described in
Section 881(c)(3)(A) of the Code; and (iv) such beneficial owner satisfies the
certification requirement (described generally below) set forth in Section
871(h) (in the case of individuals) or Section 881(c) (in the case of foreign
corporations) of the Code and the Regulations thereunder.

     To satisfy the certification requirement referred to in (iv) above, the
beneficial owner of a Discount Note, or a financial institution holding the
Discount Note on behalf of such owner, must provide, in accordance with
specified procedures, Holdings or its paying agent, as the case may be, with a
statement to the effect that the beneficial owner is a Non-United States Holder.
Such requirement generally will be met if (1) the beneficial owner provides his
name and address, signs under penalties of perjury, and certifies that he is
Non-United States Holder (which certification may be made on IRS Form W-8 (or
substitute Form W-8)) or (2) a securities clearing organization, a bank or other
financial institution holding the Discount Note on behalf of the beneficial
owner certifies, under penalties of perjury, that such statement has been
received by it and furnishes Holdings or its paying agent, as the case may be,
with a copy thereof.

     Certain Regulations provide alternative methods for satisfying the
certification requirement described above. The Regulations also require, in the
case of Discount Notes held by a foreign partnership, that (i) the certification
be provided by the partners rather than by the foreign partnership, and (ii) the
partnership provide certain information, including a United States taxpayer
identification number. The Regulations are effective for payments made after
December 31, 1997.

                                       87
<PAGE>
     If the Non-United States Holder cannot satisfy the requirements of the
"portfolio interest" exception described above, payments of premium, if any,
and interest (including original issue discount) made to Non-United States
Holders with respect to the Discount Notes will be subject to a 30% United
States withholding tax unless the beneficial owner of the Discount Note provides
Holdings or its paying agent, as the case may be, with, and keeps current (i) a
properly executed IRS Form 1001 (or successor form) claiming an exemption from
United States withholding tax under a United States income tax treaty, or (ii) a
properly executed IRS Form 4224 (or successor form) claiming such premium and/or
interest is exempt from United States withholding tax because such premium
and/or interest is effectively connected with the conduct of a United States
trade or business by the Non-United States Holder, in which case the premium
and/or interest will be subject to the United States federal income tax on net
income at the rates applicable to United States persons generally (and with
respect to corporate holders and under certain circumstances, the 30% branch
profits tax).

     INFORMATION REPORTING AND BACKUP WITHHOLDING.  In general, there is no
United States information reporting or backup withholding tax on payments to
Non-United States Holders who provide the appropriate certification described
above regarding qualifying for the portfolio interest exemption from United
States federal income tax for payments of principal or interest (including
original issue discount) on the Discount Notes.

     Payment by Holdings of principal on the Discount Notes or payment by a
United States office of a broker of the proceeds of a sale of the Discount Notes
is subject to both backup withholding and information reporting unless the
beneficial owner provides a completed IRS Form W-8 which certifies under
penalties of perjury that such owner is a Non-United States Holder who meets all
of the requirements for exemption from United States federal income tax on any
gain from the sale, exchange, or retirement of the Discount Notes.

     In general, backup withholding and information reporting will not apply to
a payment of the gross proceeds of a sale of Discount Notes effected at the
foreign office of a broker. If, however, such broker is, for United States
federal income tax purposes a United States person, or a foreign controlled
corporation, or a foreign person 50% or more of whose gross income for certain
periods is derived from activities that are effectively connected with the
conduct of a trade or business in the United States, such payments will not be
subject to backup withholding, but will be subject to information reporting
unless (i) such broker has documentary evidence in its records that the
beneficial owner is a Non-United States Holder and certain other conditions are
met, or (ii) the beneficial owner otherwise established an exemption, provided
such broker does not have actual knowledge that the payee is a United States
person. Non-United States Holders should consult their tax advisors regarding
the application of these rules to their particular situations, the availability
of an exemption therefrom and the procedure for obtaining such an exemption, if
available.

     Any amounts withheld under backup withholding will be allowed as a credit
against such holder's United States federal income tax liability and may entitle
such holder to a refund, provided the required information is furnished to the
IRS.

     GAIN ON DISPOSITION OF DISCOUNT NOTES.  A Non-United States Holder will
generally not be subject to United States federal income tax with respect to
gain recognized on disposition of the Discount Notes unless (i) the gain is
effectively connected with a trade or business of the Non-United States Holder
in the United States, or (ii) in the case of a Non-United States Holder that is
an individual, such holder is present in the United States for 183 or more days
in the taxable year of the disposition and certain other requirements are met.

     UNITED STATES FEDERAL ESTATE TAXES.  Subject to applicable treaty
provisions, the Discount Notes held at the time of death (or theretofore
transferred subject to certain retained rights or powers) by an individual who
at the time of death is not a United States citizen or domiciliary of the United
States at the date of death generally will not be included in such person's
gross estate for United States federal estate tax purposes provided that (a) the
decedent is not a 10% shareholder of Holdings, and (b) the decedent does not
hold the Discount Notes in connection with a trade or business within the United
States.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1.  THE ACQUISITION

     On July 1, 1996, Texas Olefins Company ("TOC") and a raw material supply
contract of Clarkston Corporation (defined within these financial statements and
related notes as the "Affiliate") were acquired for approximately $371 million
in a series of transactions in connection with the Acquisition. After the
transactions, TOC was merged with and into Texas Petrochemicals Corporation
becoming a 100% owned subsidiary of Texas Petrochemical Holdings, Inc. In
connection with the Acquisition, the Texas Petrochemicals Corporation issued
$175 million aggregate principal amount of Original Notes and borrowed $140
million under the Bank Credit Agreement. Texas Petrochemical Holdings, Inc.
issued $57.7 million in Discount Notes due 2007 (the "Discount Notes") for net
proceeds of $30 million and sold $43.8 million in common stock, $10 million of
which was financed under the Bank Credit Agreement. The combined proceeds from
the issuance of debt and common stock were used to finance the Acquisition. On
the closing date of the Acquisition, prior to closing, TOC sold to the previous
majority shareholder of TOC for $7.8 million in cash a ranch of approximately
1,900 acres and the livestock and personalty thereon (the "Ranch") and 80% of
the outstanding capital stock of Texas Falls Corporation ("The Falls") owned
by TOC. In June 1996, the Affiliate was dissolved and a $677,000 liquidating
dividend was declared to its shareholders.

     The sources and applications of funds required to consummate the
Acquisition are summarized below.

(1) Acquisition cost is net of cash received from the sale of The Falls and the
    Ranch for combined proceeds of $7.8 million.

(2) Represents underwriting fees, legal, accounting and other professional fees
    payable in connection with the financing of the Acquisition.

     The Acquisition was accounted for using the purchase method of accounting
and, therefore, the consolidated financial statements for the year ended June
30, 1997 reflect the purchase price allocated to the net assets acquired based
on their estimated fair values as of July 1, 1996. The fair value of tangible
assets acquired, net of liabilities assumed, was $179 million. The balance of
the purchase price, $184 million, was recorded as goodwill and is being
amortized over 40 years utilizing the straight-line method.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

     The following unaudited pro forma combined statement of income assumes the
Acquisition occurred on June 1, 1995. The pro forma combined statement of income
reflects several adjusting entries, including but not limited to, increased
depreciation and amortization as a result of the increased basis in fixed assets
and goodwill and increased interest expense from the incurrance of additional
debt. The results are not necessarily indicative of the results which would
actually have occurred if the purchase had taken place at June 1, 1995. Amounts
are in millions, except share amounts.

2.  NATURE OF OPERATIONS

     The Company through its facility in Houston, Texas is the largest producer
of butadiene and butene-1, and the third largest producer of MTBE, in North
America, in terms of production capacity. In addition, the Company is the sole
producer of diisobutylene and isobutylene concentrate in the United States and
is the largest domestic merchant supplier of high purity isobutylene to the
chemical market. The Company's products include: (i) butadiene, primarily used
to produce synthetic rubber; (ii) MTBE, used as an oxygenate and octane enhancer
in gasoline; (iii) n-butylenes (butene-1 and butene-2), used in the manufacture
of plastic resins, fuel additives and synthetic alcohols; and (iv) specialty
isobutylenes, primarily used in the production of specialty rubbers, lubricant
additives, detergents and coatings.

     The Company's principal feedstocks are crude butadiene, isobutane and
methanol. The Company purchases a significant portion of its crude butadiene
requirements at prices, which are adjusted based on the Company's selling price
of butadiene as well as the cost of natural gas used to produce butadiene,
thereby providing the Company with a fixed profit on such sales. Methanol and
isobutane are purchased at prices linked to prevailing market prices.

     In June 1996 the Company's Board of Directors approved a change in the
Company's fiscal year end to June 30 from May 31. Accordingly, the accompanying
combined financial statements include results of operations and cash flows for
the one month transition period.

  CASH AND CASH EQUIVALENTS

     The Company considers all highly liquid investments with a maturity of
three months or less at the date of purchase to be cash equivalents.

  INVESTMENT SECURITIES

     The Company accounts for investment securities in accordance with Statement
of Financial Accounting Standards No. 115, "Accounting for Certain Investments
in Debt and Equity Securities," (SFAS 115). Management has classified all
investments as available-for-sale. Cost is determined by specific
identification. Purchases and sales are reflected on a trade date basis.
Investment securities are carried at fair value with any unrealized gains or
losses reported as a component of stockholders' equity, net of tax.

  INVENTORIES

     Inventories consist of raw materials, finished goods and chemicals used in
processing and are valued at the lower of average cost or market.

     The Company may enter into product exchange agreements with suppliers
whereby certain inventories are exchanged for raw materials. These exchanges are
recorded at the lower of cost or market. Any resulting gains or losses from the
utilization of these exchanges are reflected in cost of chemical products sold.
Balances related to quantities due to or payable by the Company are included in
inventory.

  PROPERTY, PLANT AND EQUIPMENT

     Property, plant and equipment are recorded at cost. Turnaround costs and
other maintenance and repairs are charged to expense as incurred while
significant improvements are capitalized. Upon retirement or sale of an asset,
the asset and the related accumulated depreciation are removed from the accounts
and any resulting gain or loss is reflected in operations.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

  DEPRECIATION

     Depreciation of property, plant and equipment is computed using the
straight-line method over their estimated useful lives ranging from 3 to 31
years, with the plants being depreciated over 10 years.

  DEBT ISSUE COSTS AND OTHER

     Debt issue costs relating to the Company's long-term debt are amortized to
interest expense over the scheduled maturity of debt utilizing the interest
method. Unamortized debt issue costs relating to long-term debt retired prior to
its scheduled maturity are charged off as an extraordinary item. Other assets
include patents and catalysts, which are amortized using the straight-line
method over their useful lives ranging from 2 to 7 years.

  IMPAIRMENT OF ASSETS

     Prior to June 1, 1995, the Company recognized impairment of investments in
land and property, plant and equipment at the time when a decline in value of an
asset was determined to be permanent. Effective June 1, 1995, the Company
adopted SFAS No. 121, "Impairment of Long-Lived Assets and Assets to be
Disposed of." During the twelve months ended May 31, 1996, the Company
evaluated the carrying value of its investment in land in light of the possible
sale of these assets in the foreseeable future and considering the criteria of
SFAS No. 121, determined that an impairment write-down was necessary. As a
result, the Company recorded a provision for estimated impairment of $12.6
million, with an associated tax benefit of $4.7 million, to write-down certain
investments in land to estimated fair market value. Actual sales proceeds from
investments in land may differ from the carrying amounts.

  REVENUE RECOGNITION

     The Company recognizes revenue from sales of refined products in the period
of delivery.

  INCOME TAXES

     The Company accounts for income taxes in accordance with SFAS No. 109,
"Accounting for Income Taxes," which requires that deferred taxes be provided
at enacted tax rates on temporary differences between the carrying amounts of
assets and liabilities for financial and tax reporting purposes.

     The Affiliate of the Predecessor has elected for federal tax purposes to be
taxed under provisions of Subchapter S of the Internal Revenue Code. This
election requires the stockholders to include the Affiliate's net earnings,
losses and credits in their own income for tax purposes. Accordingly, the
Affiliate generally is not liable for federal income taxes and no provision for
federal income taxes is included in the accompanying financial statements. For
the periods prior to July 1, 1996, pro forma net income reflects the effect on
the combined company as if the Affiliate was a taxable entity for income tax
purposes. The Affiliate's articles of incorporation require its board of
directors to declare a payment of a cash dividend to its shareholders of no less
than 110% of the maximum individual federal income tax rate under the Internal
Revenue Code for each calendar year, payable within 30 days after the Affiliate
files its tax return.

  EMPLOYEE STOCK OWNERSHIP PLAN

     The balance of the note receivable from the Employee Stock Ownership Plan
(see Note 11), is recorded as a contra account in the stockholder's equity
section of the balance sheet.

  MANAGEMENT ESTIMATES

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

  RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

     During 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards ("SFAS") No. 128 "Earnings per Share," SFAS
No. 129 "Disclosure of Information about Capital Structure," SFAS No. 130,
"Reporting Comprehensive Income," and SFAS No. 131, "Disclosures about
Segments of an Enterprise and Related Information." SFAS No. 128 is effective
for financial statements for both interim and annual periods ending after
December 15, 1997. SFAS No. 129 is effective for periods ending after December
15, 1997. SFAS No. 130 and SFAS 131 are effective for fiscal years beginning
after December 15, 1997. Adoption of these pronouncements is not expected to
have a material effect on the Company's financial position, results of
operations or cash flows.

  RECLASSIFICATIONS

     Certain reclassifications have been made to previously issued financial
statements to conform to the current presentation. There is no resulting impact
on stockholders' equity or net income (loss). The Company classifies variable
compensation paid to employees as cost of goods sold. Previously, the Company
had classified this cost as selling, general and administrative expenses. The
Company has made reclassifications to the prior periods in order to conform to
the current period presentation.

4.  INVESTMENT SECURITIES

     On July 1, 1996 in connection with the Acquisition, all of the
Predecessor's equity securities were sold at their unamortized cost. As of June
30, 1996 the Predecessor held $6.8 million of equity securities with an
unamortized cost of $9.0 million and gross unrealized losses of $2.2 million.
Unrealized losses of $0.6 million and $1.4 million (net of deferred tax) related
to these securities is recorded as a component of stockholders' equity for the
twelve months ended May 31, 1996 and the one month ended June 30, 1996,
respectively. During the twelve months ended May 31, 1996 and the one month
ended June 30, 1996, gross realized gains of approximately $1.9 million and $0,
respectively, and gross realized losses of approximately $5.0 million and $0.3
million, respectively, were recognized on the sale of securities.

     The Predecessor held $3.7 million of bankers acceptance notes at May 31,
1995, with scheduled maturities of less than one year. The Predecessor also held
approximately $17.4 million of equity securities at May 31, 1995. Unrealized
losses of $3.6 million (net of deferred tax) related to these securities are
recorded as a component of stockholders' equity for the year ended May 31, 1995.
During the year ended May 31, 1995, gross realized gains of approximately $1.2
million and gross realized losses of approximately $0.05 million were recognized
on the sale of securities.

     The Bank Credit Agreement provided for term loans in the amount of $130
million, an ESOP loan of $10 million, and a revolving credit facility of up to
$40 million. Quarterly principal and interest payments are made under the Bank
Credit Agreement. The final payments under the ESOP Loan, Term A Loan and Term B
Loan are due on June 30, 2001, December 31, 2002 and June 30, 2004,
respectively. The Revolving Credit Loan Facility is currently scheduled to
expire on December 31, 2002. The debt under the Bank Credit Agreement bears
interest, at the option of the borrower, based on the LIBOR rate plus a margin
(2.5% and 3% at June 30, 1997) or the greater of the prime rate and the federal
funds rate plus 1/2% plus a margin (1.5% at June 30, 1997). Substantially all
assets of the Company are pledged as collateral under the Bank Credit Agreement.
The Original Notes and Notes are due 2006 and bear interest at 11 1/8% payable
semiannually on January 1 and July 1. The Discount Notes are due 2007 and bear
interest at 13 1/2% payable semi-annually on January 1 and July 1, beginning in
2002. The Bank Credit Agreement and the Indentures include certain restrictive
covenants, which include but are not limited to, limitations on capital
expenditures, indebtedness, investments and sales of assets and subsidiary
stock. Additionally, the Bank Credit Agreement requires the Company to maintain
certain financial ratios. As of June 30, 1997 the Company obtained an amendment
to the Bank Credit Agreement to waive the debt to EBITDA ratio at June 30, 1997
and to update the financial ratios relating to fixed charge coverage and debt to
EBITDA for fiscal 1998.

     On March 13, 1997 the Company closed on the sale of $50 million aggregate
principal amount of Notes in a Rule 144A offering. The terms of the Notes were
identical, except as to the offering price, to the terms of the Original Notes
issued by the Company in July 1996. The Company applied the net proceeds
received from the offering to reduce the Term A Loan. The Company subsequently
completed an exchange offer to exchange the unregistered securities for
identical securities, which have been registered under the Securities Act.

     The fair value of the Original Notes and Notes in the aggregate, based on
quoted market prices, was approximately $242 million as of June 30, 1997. The
long-term debt under the Bank Credit Agreement carries a floating interest rate,
therefore, the Company estimates that the carrying amount of such debt was not
materially different from its fair value as of June 30, 1997. There currently is
not an active market for the Discount Notes, therefore, the Company estimates
that the fair value, based on current interest rates available to the Company
for similar debt instruments, was approximately $37 million as of June 30, 1997.

     Pro Forma income tax provision assumes that the income of the Affiliate,
which is a Subchapter S Corporation and accordingly pays no federal income tax,
was taxable to the Predecessor based on the Predecessor's effective tax rate.

     The provision for income taxes differs from the amount computed by applying
the statutory federal income tax rate to income from continuing operations. The
reasons for this difference are as follows:

     The Company and Hollywood Marine, Inc. formed a limited partnership,
Hollywood/Texas Olefins, Ltd., to operate four barges capable of transporting
chemicals. The Company is a 50% limited partner in the limited partnership. The
Company accounts for this investment under the equity method and records its
portion of the limited partnership's net income as other income in the
accompanying statement of operations. Summarized financial information of the
partnership has not been presented because the Company's investment in and its
proportionate share of the partnership's operations are not material.

  LEASE COMMITMENTS

     The Company leases tank cars under noncancelable operating leases. Under
the terms of the lease agreements, the Company is reimbursed by customers at a
fixed rate per mile, based on the distance the tank cars travel. Reimbursements
were approximately $0.8 million, $0.04 million, $0.8 million and $0.7 million,
for the year ended June 30, 1997, for the one month period ended June 30, 1996,
for the twelve months ended May 31, 1996 and for the year ended May 31, 1995,
respectively. The Company is also obligated under an operating lease to
Hollywood/Texas Olefins, Ltd. for the rental of two barges.

     Total rent expense was approximately $3.9 million, $0.4 million, $4.8
million and $4.4 million (net of reimbursements described above and including
$1.8 million, $0.2 million, $2.0 million and $2.0 million for

  PURCHASE COMMITMENTS

     The Company has purchase commitments incident to the ordinary conduct of
business. The prices of such purchase commitments are based on formulas, which
are determined from the prevailing market rate for such products. These
commitments generally have cancellation provisions given proper notification.

  LITIGATION

     The Company is involved in various routine legal proceedings which are
incidental to the business. Management of the Company is vigorously defending
such matters and is of the opinion that their ultimate resolution will not have
a material adverse impact on the Company.

  STOCKHOLDER ACTION

     Effective July 28, 1995 the Predecessor's Board of Directors approved the
redemption of 25,000 shares of Class A common stock and 1,565,670 shares of
Class B common stock from certain stockholders for total consideration of
approximately $95,000,000. The redemption was paid with cash of approximately
$80,000,000 and with the issuance to a former stockholder of a $15,000,000
promissory note due November 1, 1995 collateralized by 915,000 shares of Class B
common stock and the personal guarantee of an officer of the Predecessor. In
connection with the above redemption the Predecessor's Board of Directors
approved the sale of (1) 351,670 shares of Class B treasury stock to certain
officers of the Predecessor and to a trust at the price of $60 per share, and
(2) 25,000 shares to Class A treasury stock to an officer of the Predecessor at
a price of $60 per share. On September 12, 1995, the Predecessor's stockholders
did not ratify the stock redemption and other transactions described above.
These items were not ratified due to the abstention of the trustee representing
a majority of Class B common stock. The abstaining stockholder has the right,
for up to two years from September 12, 1995, to vote in favor of or against the
aforementioned transaction or take other action on behalf of the trust
beneficiaries. The Company cannot predict what action the abstaining stockholder
will take. Accordingly, the Company cannot determine the effect, if any, of this
uncertainty on its financial position, results of operations or cash flows.

  ENVIRONMENTAL REGULATION

     The Company's operations are subject to federal, state and local laws and
regulations administered by the U.S. Environmental Protection Agency, the U.S.
Coast Guard, the Army Corps of engineers, the Texas Natural Resource
Conservation Commission, the Texas General Land Office, the Texas Department of
Health and various local regulatory agencies. The Company holds all required
permits and registrations necessary to comply substantially with all applicable
environmental laws and regulations, including permits and registrations for
wastewater discharges, solid and hazardous waste disposal and air emissions, and
management believes that the Company is in substantial compliance with all such
laws and regulations. While management does not expect the cost of compliance
with existing environmental laws will have a material adverse effect on the
Company's financial condition, results of operations or cash flows, there can

                                      F-17
<PAGE>
              TEXAS PETROCHEMICAL HOLDINGS, INC. (AND PREDECESSOR)
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
be no assurance that future legislation, regulation or judicial or
administrative decisions will not have such an effect.

     Under federal and state environmental laws, companies may be liable for
remediation of contamination at on-site and off-site waste management and
disposal areas. Management believes that the Company is not likely to be
required to incur remediation costs related to its management, transportation
and disposal of solid and hazardous materials and wastes, or to its pipeline
operations. If the Company were to be required to incur such costs, however,
management believes that such costs would not have a material adverse effect on
the Company's results of operations. In addition, under the terms of the 1984
purchase agreement, the prior owner of the Houston facility, Petro-Tex, has
indemnified the Company for liability arising from off-site disposal of any
materials prior to June 1984. Notwithstanding the terms of the indemnity, in
July 1994 Petro-Tex filed a claim for indemnity against the Company for any
costs that may be attributable to Petro-Tex for the cleanup of the Malone site
in Texas City, Texas. Petro-Tex and many other companies along the Gulf Coast
allegedly sent wastes to the Malone site for disposal in the 1970s and possibly
the early 1980s. Malone has been subject to several state enforcement actions
regarding its waste disposal practices, and TNRCC has revoked Malone's permits
to operate its facilities. It is not known whether the site will require
remediation or at what cost. The Company believes that it has meritorious
defenses to Petro-Tex's claim and intends to contest the claim vigorously.
Although no on-site contamination has been identified as requiring remediation,
management believes that certain areas of the Houston facility were historically
used for waste disposal. Based on limited, currently available information about
these waste disposal areas and their contents, the Company believes that, if
such remediation becomes necessary, any remediation costs would not have a
material adverse effect on the Company's financial condition or results of
operations. The Petro-Tex indemnity does not extend to these on-site waste
disposal areas or their contents.

  PREDECESSOR COMMITMENTS

     During 1996, the Predecessor's Board of Directors approved the cancellation
of all of the following stock purchase agreements, stock option agreements and
salary continuation agreements in anticipation of the Acquisition.

  STOCK PURCHASE AGREEMENTS

     The Predecessor's Board of Directors approved a stock purchase agreement
with certain officers who own 185,000 shares of the Predecessor's outstanding
Class A common stock and 1,081,670 shares of the Predecessor's outstanding Class
B common stock. Under the terms of this agreement in the event any of these
officers ceases full time employment with the Predecessor or in the event of the
stockholder's death, the Predecessor must redeem all of the stockholder's shares
at a redemption price of $60 per share. This agreement superseded the previous
stock purchase agreements of the Predecessor which are described in the
following paragraphs.

     The Predecessor entered into a stock purchase agreement with a certain
minority stockholder who owns 20,000 shares of the Predecessor's outstanding
Class A common stock and 80,000 shares of the Predecessor's outstanding Class B
common stock. Under the terms of this agreement, in the event of the
stockholder's death, the Predecessor must redeem all shares owned by the
deceased stockholder at a formula price, which is adjusted annually. At May 31,
1995, the formula price per share was approximately $58.

     The Predecessor entered into a death benefit agreement with an officer of
the Predecessor who owns 660,000 shares of Class B common stock of the
Predecessor. This agreement provides that in the event of the death of the
officer, the Predecessor is obligated to redeem the shares at a price of $60 per
share with twenty-five percent of the purchase price payable at closing and the
balance payable in five equal annual installments plus interest at the rate of
eight percent per annum. This agreement replaces a previous

                                      F-18
<PAGE>
              TEXAS PETROCHEMICAL HOLDINGS, INC. (AND PREDECESSOR)
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
agreement that obligated the Predecessor to redeem the shares in the event of
the death of the officer at a price of $80 per share.

     The Predecessor entered into a stock purchase agreement with certain of its
minority stockholders who own 171,000 shares of the Predecessor's outstanding
common stock. Under the terms of this agreement, such stockholders may sell
their shares to the Predecessor at a formula price, which is adjusted annually.
Under this agreement, the Predecessor is obligated to redeem the shares in the
event of the death of the stockholder at the formula price. At May 31, 1995, the
formula price per share was approximately $54.

     The Predecessor also entered into a Section 303 stock purchase agreement
with an officer of the Predecessor who owns 85,000 shares of the Predecessor's
outstanding common stock. This agreement allows for the officer's estate to
require the Predecessor to redeem the necessary shares so as to pay estate taxes
and funeral and administrative expenses upon the death of the officer. Under the
terms of this agreement, the redemption price per share will be based upon the
value of the shares as reflected on the federal estate tax return.

     Additionally, the Predecessor entered into separate stock purchase
agreements with an officer of the Predecessor and his spouse who own 500,000
shares of the Predecessor's outstanding common stock as part of a community
estate. The agreement with the officer requires the Predecessor to redeem
250,000 shares from the community estate upon the officer's death at a price of
$90 per share with twenty five percent of the redemption price payable at
closing and the balance payable in five annual installments plus interest at the
rate of eight percent per annum. The agreement with the officer's spouse allows
her to require the Predecessor to redeem the 250,000 shares from the community
estate not redeemed as part of the officer's agreement for a period of one year
subsequent to the officer's death at the same price and payable in the same
manner as set forth in the officer's agreement. Additionally, the spouse's
agreement requires the Predecessor to redeem 250,000 shares of the stock from
the community estate in the event that she predeceases the officer at a price of
$90 per share with sixty percent of the redemption price payable at closing and
the balance payable in thirty-six equal monthly installments plus interest at
the rate of eight percent per annum.

     All of the Affiliate's common stock is subject to a stock purchase
agreement. Under the terms of the stock purchase agreement, the Affiliate is
obligated to redeem all of a stockholder's shares in the event of death and has
an option to redeem all of a stockholder's shares in certain other instances.
The redemption price is equal to the Affiliate's adjusted book value, as defined
in the agreement, divided by the number of outstanding shares. At May 31, 1995,
the redemption price per share was $8.15. Of the total redemption amount, 25% is
to be paid in cash with the remaining balance to be paid in 42 equal monthly
installments as evidenced by an interest bearing promissory note.

  STOCK OPTION AGREEMENTS

     The Predecessor entered into stock option agreements with two of its
officers, which granted them the option to purchase 100,000 shares of common
stock. The option purchase price for the shares is $40 per share. At May 31,
1995, 30,000 shares were exercisable. During the fiscal year ended May 31, 1994,
one of the officers forfeited his option to purchase 50,000 shares of common
stock. In the event the option is exercised, the Predecessor and the officers
will enter into stock purchase agreements. Under the terms of the agreement,
transfer of the stock is restricted and only the Predecessor, at its option, may
redeem the stock. However, upon death of the officer, the Predecessor is
obligated to redeem the officer's shares. In all instances the redemption price
will be the greater of the formula price in the agreement or $40 per share. At
May 31, 1995 the formula price was approximately $54 per share.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

  SALARY CONTINUATION AGREEMENTS

     The Predecessor entered into salary continuation agreements with three of
its officers. The agreements provide that if the officer is an employee of the
Predecessor upon death, an amount ranging from $10,000 to $25,000 would be
payable monthly to his estate for a period of five years.

11.  EMPLOYEE BENEFITS

  PROFIT SHARING PLAN

     The Company has a noncontributory profit sharing plan that covers all
full-time employees that have completed one year or more of service. Employees
can contribute up to 10% of their base compensation to a tax deferred fund which
is matched by the Company at the rate of $.25 per one dollar contributed by the
employee up to 6% of the employee's base compensation. The Company's expense to
match employee contributions was $169,591, $14,786, $195,627 and $180,000 for
the year ended June 30, 1997, for the one month period ended June 30, 1996, for
the twelve month period ended May 31, 1996 and for the year ended May 31, 1995,
respectively. Additionally, the Company made additional discretionary
contributions to the plan which amounted to approximately $1.1 million, $0.2
million, $2.4 million and $2.6 million for the year ended June 30, 1997, for the
one month period ended June 30, 1996, for the twelve month period ended May 31,
1996 and for the year ended May 31, 1995, respectively. The Company's
contributions vest with the employee at a rate of 20% per year.

  EMPLOYEE STOCK OWNERSHIP PLAN

     In connection with the Acquisition, the Company established an Employee
Stock Ownership Plan (the "ESOP"), covering substantially all full-time
employees of the Company. The ESOP borrowed $10 million under the Bank Credit
Agreement to purchase 100,000 shares of the Company's Common Stock at the
closing of the Acquisition. The shares of Common Stock purchased by the ESOP
were pledged as security for the ESOP Loan, and such shares will be released and
allocated to ESOP participants' accounts as the ESOP Loan is discharged. For
employees whose employment commenced prior to October 1, 1996 and who have
attained 21 years, participation begins as of the Acquisition date or the date
of commencement of the participant's employment. A participant's ESOP account
vests at the rate of 20% per year. The Company's contributions to the ESOP,
which are used to retire principal and interest on the loan is reported as
compensation expense. Principal and interest payments made for the year ended
June 30, 1997 amounted to $2.7 million.

  CASH BONUS PLAN LIABILITY

     In connection with the Acquisition, the Predecessor established the $35
million Cash Bonus Plan covering substantially all employees of the Predecessor
(or certain affiliates of the Predecessor) and covering the employees of certain
third-party contractors who have contributed to the success of the Predecessor.
All participants of the plan as of July 2, 1996 were distributed 10% of the cash
bonus in August 1996, and the remaining amount is to be paid in sixteen
quarterly installments which began in October 1996.

12.  RELATED PARTY TRANSACTIONS

     Prior to the Acquisition, the Predecessor made contributions from time to
time to a charitable organization that is an affiliate of the Predecessor.

13.  CONCENTRATION OF CREDIT RISK

     The Company sells its products primarily to chemical and petroleum based
companies in North America. For the year ended June 30, 1997, the one month
period ended June 30, 1996, the twelve month period ended May 31, 1996 and the
year ended May 31, 1995 approximately 41%, 46%, 50%, and 35%,

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
respectively, of the Company's sales were to four customers. The Company had two
customers, which represented 11% and 17% of sales during the year ended June 30,
1997, 14% and 16% of sales during the one month period ended June 30, 1996, and
16% and 19% of sales during the twelve months ended May 31, 1996. The Company
had one customer, which represented 12% of sales during the year ended May 31,
1995. The Company performs ongoing credit evaluations of its customers and
generally does not require collateral for accounts receivable. The Company's
credit losses have been minimal.

     The Company maintains its cash deposits and short-term investments with a
major bank and a financial services company which at certain times exceed the
federally insured limits. Management assesses the financial condition of these
institutions and believes that any possible credit loss is minimal.

14.  FINANCIAL INSTRUMENTS

     At June 30, 1997 the Company estimated that the carrying value and fair
value of its financial instruments, other than long-term debt (See Note 6), were
approximately equal due to the short-term nature of the instruments. Such
instruments include cash and cash equivalents, accounts receivable and accounts
payable.

ITEM 14.  INDEMNIFICATION OF OFFICERS AND DIRECTORS.

     Holding's Certificate of Incorporation, as amended, and Bylaws incorporate
substantially the provisions of the Delaware General Corporation Law ("DGCL")
providing for indemnification of directors and officers of Holdings against
expenses, judgments, fines, settlements and other amounts actually and
reasonably incurred in connection with any proceeding arising by reason of the
fact that such person is or was an officer or director of Holdings or is or was
serving at the request of Holdings as a director, officer or employee of another
corporation, partnership, joint venture, trust, employee benefit plan or other
enterprise.

     As permitted by Section 102 of the DGCL, Holding's Certificate of
Incorporation, as amended, contains provisions eliminating a director's personal
liability for monetary damages to Holdings and its stockholders arising from a
breach of a director's fiduciary duty except for liability (a) for any breach of
the director's duty of loyalty to Holdings or its stockholders, (b) for acts or
omissions not in good faith or which involve intentional misconduct or a knowing
violation of law, (c) under Section 174 of the DGCL, or (d) for any transaction
from which the director derived an improper personal benefit.

     Section 145 of the DGCL provides generally that a person sued as a
director, officer, employee or agent of a corporation may be indemnified by the
corporation for reasonable expenses, including attorneys' fees, if in the case
of other than derivative suits such person has acted in good faith and in a
manner such person reasonably believed to be in or not opposed to the best
interests of the corporation (and, in the case of a criminal proceeding, had no
reasonable cause to believe that such person's conduct was unlawful). In the
case of a derivative suit, an officer, employee or agent of the corporation
which is not protected by the Certificate of Incorporation may be indemnifed by
the corporation for reasonable expenses, including attorneys' fees, if such
person has acted in good faith and in a manner such person reasonably believed
to be in or not opposed to the best interests of the corporation, except that no
indemnification shall be made in the case of a derivative suit in respect of any
claim as to which an officer, employee or agent has been adjudged to be liable
to the corporation unless that person is fairly and reasonably entitled to
indemnity for proper expenses. Indemnification is mandatory in the case of a
director or officer who is successful on the merits in defense of a suit against
such person.

     Pursuant to policies of Directors and Officers Liability and Company
Reimbursement insurance with total limits of $10,000,000, the Directors and
Officers of Holdings are insured, subject to the limits, retention, exceptions
and other terms and conditions of such policies, against liability for any
actual or alleged error or misstatement or misleading statement or act or
omission or neglect or breach of duty while acting in their capacities as
Directors or Officers of Holdings.

                                      II-1
<PAGE>
     Holdings has entered into Indemnity Agreements with its directors and
certain officers pursuant to which Holdings generally is obligated to indemnify
its directors and such officers to the full extent permitted by the DGCL, as
described above.

ITEM 15.  SALE OF UNREGISTERED SECURITIES.

     In connection with the Acquisition, on July 1, 1996 Holdings (i) sold
$57,650,103.55 principal amount of Discount Notes for $30,000,000 cash to the
Huff Fund, (ii) sold $43.8 million of its Common Stock for cash to an investor
group led by Gordon A. Cain and Sterling, and (iii) issued $6.2 million of its
Common Stock for the shares contributed by certain shareholders of TOC and TPC

and sale of the Discount Notes and Common Stock for cash were exempt from
registration pursuant to Section 4(2) of the Securities Act. The offer and sale
of $6.2 million in Common Stock in a share exchange was exempt from registration
pursuant to Section 4(2) of the Securities Act.

ITEM 17.  UNDERTAKINGS.

     (a)  The undersigned Company hereby undertakes:

          (1)  To file, during any period in which offers or sales are being
     made, a post-effective amendment to this registration statement:

             (i)  To include any prospectus required by section 10(a)(3) of the
        Securities Act of 1933.

             (ii)  To reflect in the prospectus any facts or events arising
        after the effective date of the registration statement (or the most
        recent post-effective amendment thereof) which, individually or in the
        aggregate, represent a fundamental change in the information set forth
        in the registration

                                      II-3
<PAGE>
        statement. Notwithstanding the foregoing, any increase or decease in
        volume of securities offered (if the total dollar value of securities
        offered would not exceed that which was registered) and any deviation
        from the low or high end of the estimated maximum offering range may be
        reflected in the form of prospectus filed with the Commission pursuant
        to Rule 424(b) if, in the aggregate, the changes in volume and price
        represent no more than a 20% change in the maximum aggregate offering
        price set forth in the "Calculation of Registration Fee" table in the
        effective registration statement.

             (iii)  To include any material information with respect to the plan
        of distribution not previously disclosed in the registration statement
        or any material change to such information in the registration
        statement.

          (2)  That, for the purpose of determining any liability under the
     Securities Act of 1933, each such post-effective amendment shall be deemed
     to be a new registration statement relating to the securities offered
     therein, and the offering of such securities at that time shall be deemed
     to be the initial bona fide offering thereof.

          (3)  To remove from registration by means of a post-effective
     amendment any of the securities being registered which remain unsold at the
     termination of the offering.

     (b)  Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers and controlling
persons of the registrant pursuant to the foregoing provisions, or otherwise,
the registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than payment by the registrant
of expenses incurred or paid by a director, officer or controlling person of the
registrant in the successful defense of any action, suit or proceeding) is
asserted by such director, officer of controlling person in connection with the
securities being registered, the registrant will, unless in the opinion of its
counsel the matter has been settled by controlling precedent, submit to a court
of appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the Act and will be governed by the final
adjudication of such issue.

                                     WAIVER

      This Waiver dated as of March 3, 1998 ("Waiver"), is made by The Huff
Alternative Income Fund, L.P., the sole holder of the Securities (as defined in
the Indenture referred to below) ("Holder"), in favor of Texas Petrochemical
Holdings, Inc., the issuer of such Securities ("Company").

                                  INTRODUCTION

      Reference is made to the Indenture dated as of July 1, 1996 (the
"Indenture") among the Company, TPC Holding Corporation, and Fleet National
Bank, as trustee. Capitalized terms used in this Waiver and not otherwise
defined shall have the respective meanings given those terms in the Indenture.
The Holder is the holder of the Senior Discount Notes due 2007 represented by
certificate No. 1 (CUSIP No. 882649 AA 4) in the original principal amount of
$57,650,103.55, which are the sole Securities issued under the Indenture as of
the date hereof. The Company has requested that the Holder waive, and the Holder
has agreed to waive, the requirements of Section 10.09(a)(ii) and (iii) of the
Indenture to the extent such requirements would not be met by the Investment (as
defined below).

      Therefore, on the terms and conditions of this Waiver:

      1. The Holder hereby (a) waives, for a single transaction, the
requirements of Sections 10.09(a)(ii) and (iii) of the Indenture to the extent,
if any, such requirements would not be met by the investment by a Restricted
Subsidiary of Holdings of up to $1,000 for a 50% interest in a corporation
organized to conduct certain business in Venezuela (the "Investment") and (b)
provided that the Investment complies with the terms of the Indenture other than
Sections 10.09(a)(ii) and (iii), consents to the Investment.

      2. This Waiver shall be effective as of the date hereof when delivered to
the Trustee.

      3. This Waiver is limited solely to the purposes and to the extent
provided herein and shall not be construed to be a waiver of, except as
specifically provided in Section 1 of this Waiver, (a) any term, condition, or
provision of the Indenture or (b) any Default or Event of Default that has or
may have occurred or occurs after the date hereof. Except as specifically
provided herein, the Indenture will continue in full force and effect.

                                       -1-
<PAGE>
      4. The Company agrees to notify the Holder within three Business Days
after the closing of the Investment.

      5. This Waiver (a) shall be binding on the parties hereto and their
respective successors and assigns and shall inure to the benefit of the parties
hereto and their respective successors and assigns, (b) may be executed in
multiple counterparts and may be delivered by telecopier transmission, (c)
constitutes the entire agreement among the parties hereto with respect to the
matters addressed herein, and (d) shall be governed by, and construed in
accordance with, the laws of the State of New York.
